PMID- 29166589 TI - Granulocyte-Monocyte Progenitors and Monocyte-Dendritic Cell Progenitors Independently Produce Functionally Distinct Monocytes. AB - Granulocyte-monocyte progenitors (GMPs) and monocyte-dendritic cell progenitors (MDPs) produce monocytes during homeostasis and in response to increased demand during infection. Both progenitor populations are thought to derive from common myeloid progenitors (CMPs), and a hierarchical relationship (CMP-GMP-MDP monocyte) is presumed to underlie monocyte differentiation. Here, however, we demonstrate that mouse MDPs arose from CMPs independently of GMPs, and that GMPs and MDPs produced monocytes via similar but distinct monocyte-committed progenitors. GMPs and MDPs yielded classical (Ly6Chi) monocytes with gene expression signatures that were defined by their origins and impacted their function. GMPs produced a subset of "neutrophil-like" monocytes, whereas MDPs gave rise to a subset of monocytes that yielded monocyte-derived dendritic cells. GMPs and MDPs were also independently mobilized to produce specific combinations of myeloid cell types following the injection of microbial components. Thus, the balance of GMP and MDP differentiation shapes the myeloid cell repertoire during homeostasis and following infection.

AB - Pancreatic-islet inflammation contributes to the failure of beta cell insulin secretion during obesity and type 2 diabetes. However, little is known about the nature and function of resident immune cells in this context or in homeostasis. Here we show that interleukin (IL)-33 was produced by islet mesenchymal cells and enhanced by a diabetes milieu (glucose, IL-1beta, and palmitate). IL-33 promoted beta cell function through islet-resident group 2 innate lymphoid cells (ILC2s) that elicited retinoic acid (RA)-producing capacities in macrophages and dendritic cells via the secretion of IL-13 and colony-stimulating factor 2. In turn, local RA signaled to the beta cells to increase insulin secretion. This IL 33-ILC2 axis was activated after acute beta cell stress but was defective during chronic obesity. Accordingly, IL-33 injections rescued islet function in obese mice. Our findings provide evidence that an immunometabolic crosstalk between islet-derived IL-33, ILC2s, and myeloid cells fosters insulin secretion. PMID- 29166591 TI - A CD103+ Conventional Dendritic Cell Surveillance System Prevents Development of Overt Heart Failure during Subclinical Viral Myocarditis. AB - Innate and adaptive immune cells modulate heart failure pathogenesis during viral myocarditis, yet their identities and functions remain poorly defined. We utilized a combination of genetic fate mapping, parabiotic, transcriptional, and functional analyses and demonstrated that the heart contained two major conventional dendritic cell (cDC) subsets, CD103+ and CD11b+, which differentially relied on local proliferation and precursor recruitment to maintain their tissue residency. Following viral infection of the myocardium, cDCs accumulated in the heart coincident with monocyte infiltration and loss of resident reparative embryonic-derived cardiac macrophages. cDC depletion abrogated antigen-specific CD8+ T cell proliferative expansion, transforming subclinical cardiac injury to overt heart failure. These effects were mediated by CD103+ cDCs, which are dependent on the transcription factor BATF3 for their development. Collectively, our findings identified resident cardiac cDC subsets, defined their origins, and revealed an essential role for CD103+ cDCs in antigen specific T cell responses during subclinical viral myocarditis. PMID- 29166593 TI - Neural correlates of improvements in personality and behavior following a neurological event. AB - Research on changes in personality and behavior following brain damage has focused largely on negative outcomes, such as increased irritability, moodiness, and social inappropriateness. However, clinical observations suggest that some patients may actually show positive personality and behavioral changes following a neurological event. In the current work, we investigated neuroanatomical correlates of positive personality and behavioral changes following a discrete neurological event (e.g., stroke, benign tumor resection). Patients (N = 97) were rated by a well-known family member or friend on five domains of personality and behavior: social behavior, irascibility, hypo-emotionality, distress, and executive functioning. Ratings were acquired during the chronic epoch of recovery, when psychological status was stabilized. We identified patients who showed positive changes in personality and behavior in one or more domains of functioning. Lesion analyses indicated that positive changes in personality and behavior were most consistently related to damage to the bilateral frontal polar regions and the right anterior dorsolateral prefrontal region. These findings support the conclusion that improvements in personality and behavior can occur after a neurological event, and that such changes have systematic neuroanatomical correlates. Patients who showed positive changes in personality and behavior following a neurological event were rated as having more disturbed functioning prior to the event. Our study may be taken as preliminary evidence that improvements in personality and behavior following a neurological event may involve dampening of (premorbidly) more extreme expressions of emotion. PMID- 29166592 TI - HIV Envelope Glycoform Heterogeneity and Localized Diversity Govern the Initiation and Maturation of a V2 Apex Broadly Neutralizing Antibody Lineage. AB - Understanding how broadly neutralizing antibodies (bnAbs) to HIV envelope (Env) develop during natural infection can help guide the rational design of an HIV vaccine. Here, we described a bnAb lineage targeting the Env V2 apex and the Ab Env co-evolution that led to development of neutralization breadth. The lineage Abs bore an anionic heavy chain complementarity-determining region 3 (CDRH3) of 25 amino acids, among the shortest known for this class of Abs, and achieved breadth with only 10% nucleotide somatic hypermutation and no insertions or deletions. The data suggested a role for Env glycoform heterogeneity in the activation of the lineage germline B cell. Finally, we showed that localized diversity at key V2 epitope residues drove bnAb maturation toward breadth, mirroring the Env evolution pattern described for another donor who developed V2 apex targeting bnAbs. Overall, these findings suggest potential strategies for vaccine approaches based on germline-targeting and serial immunogen design. PMID- 29166594 TI - Individual differences in processing emotional images after reading disgusting and neutral sentences. AB - The present study examined the extent to which Event Related Potentials (ERPs) evoked by disgusting, threatening and neutral photographic images were influenced by disgust propensity, disgust sensitivity and attentional control following exposure to disgusting information. Emotional cognition was manipulated by instructing participants to remember either disgusting or neutral sentences; participants in both groups then viewed emotional images while ERPs were recorded. Disgust propensity was associated with a reduced Late Positive Potential (LPP) gap between threatening and neutral stimuli (an effect driven by a rise in the LPP for neutral images) but only amongst individuals who were exposed to disgusting sentences. The typical LPP increase for disgust over neutral was reduced by attentional shifting capacity but only for individuals who were not previously exposed to disgust. There was also a persistent occipital shifted late positivity that was enhanced for disgust for the entire LPP window and was independent of exposure. Results suggest that emotion specific ERP effects can emerge within the broad unpleasant emotional category in conjunction with individual differences and prior emotional exposure. These results have important implications for the ways in which the perception of emotion is impacted by short term cognitive influences and longer term individual differences. PMID- 29166595 TI - Positive and Negative Regulation of the Master Metabolic Regulator mTORC1 by Two Families of Legionella pneumophila Effectors. AB - All pathogens must acquire nutrients from their hosts. The intracellular bacterial pathogen Legionella pneumophila, the etiological agent of Legionnaires' disease, requires host amino acids for growth within cells. The mechanistic target of rapamycin complex 1 (mTORC1) is an evolutionarily conserved master regulator of host amino acid metabolism. Here, we identify two families of translocated L. pneumophila effector proteins that exhibit opposing effects on mTORC1 activity. The Legionella glucosyltransferase (Lgt) effector family activates mTORC1, through inhibition of host translation, whereas the SidE/SdeABC (SidE) effector family acts as mTORC1 inhibitors. We demonstrate that a common activity of both effector families is to inhibit host translation. We propose that the Lgt and SidE families of effectors work in concert to liberate host amino acids for consumption by L. pneumophila. PMID- 29166596 TI - The GCN2-ATF4 Signaling Pathway Induces 4E-BP to Bias Translation and Boost Antimicrobial Peptide Synthesis in Response to Bacterial Infection. AB - Bacterial infection often leads to suppression of mRNA translation, but hosts are nonetheless able to express immune response genes through as yet unknown mechanisms. Here, we use a Drosophila model to demonstrate that antimicrobial peptide (AMP) production during infection is paradoxically stimulated by the inhibitor of cap-dependent translation, 4E-BP (eIF4E-binding protein; encoded by the Thor gene). We found that 4E-BP is induced upon infection with pathogenic bacteria by the stress-response transcription factor ATF4 and its upstream kinase, GCN2. Loss of gcn2, atf4, or 4e-bp compromised immunity. While AMP transcription is unaffected in 4e-bp mutants, AMP protein levels are substantially reduced. The 5' UTRs of AMPs score positive in cap-independent translation assays, and this cap-independent activity is enhanced by 4E-BP. These results are corroborated in vivo using transgenic 5' UTR reporters. These observations indicate that ATF4-induced 4e-bp contributes to innate immunity by biasing mRNA translation toward cap-independent mechanisms, thus enhancing AMP synthesis. PMID- 29166597 TI - Mammalian HP1 Isoforms Have Specific Roles in Heterochromatin Structure and Organization. AB - HP1 is a structural component of heterochromatin. Mammalian HP1 isoforms HP1alpha, HP1beta, and HP1gamma play different roles in genome stability, but their precise role in heterochromatin structure is unclear. Analysis of Hp1alpha /-, Hp1beta-/-, and Hp1gamma-/- MEFs show that HP1 proteins have both redundant and unique functions within pericentric heterochromatin (PCH) and also act globally throughout the genome. HP1alpha confines H4K20me3 and H3K27me3 to regions within PCH, while its absence results in a global hyper-compaction of chromatin associated with a specific pattern of mitotic defects. In contrast, HP1beta is functionally associated with Suv4-20h2 and H4K20me3, and its loss induces global chromatin decompaction and an abnormal enrichment of CTCF in PCH and other genomic regions. Our work provides insight into the roles of HP1 proteins in heterochromatin structure and genome stability. PMID- 29166598 TI - Biological Significance of the Suppression of Oxidative Phosphorylation in Induced Pluripotent Stem Cells. AB - We discovered that induced pluripotent stem cell (iPSC) clones generated from aged tissue donors (A-iPSCs) fail to suppress oxidative phosphorylation. Compared to embryonic stem cells (ESCs) and iPSCs generated from young donors (Y-iPSCs), A iPSCs show poor expression of the pluripotent stem cell-specific glucose transporter 3 (GLUT3) and impaired glucose uptake, making them unable to support the high glucose demands of glycolysis. Persistent oxidative phosphorylation in A iPSCs generates higher levels of reactive oxygen species (ROS), which leads to excessive elevation of glutathione (a ROS-scavenging metabolite) and a blunted DNA damage response. These phenotypes were recapitulated in Y-iPSCs by inhibiting pyruvate dehydrogenase kinase (PDK) or supplying citrate to activate oxidative phosphorylation. In addition, oxidative phosphorylation in A-iPSC clones depletes citrate, a nuclear source of acetyl group donors for histone acetylation; this consequently alters histone acetylation status. Expression of GLUT3 in A-iPSCs recovers the metabolic defect, DNA damage response, and histone acetylation status. PMID- 29166599 TI - Maturation of Cerebellar Purkinje Cell Population Activity during Postnatal Refinement of Climbing Fiber Network. AB - Neural circuits undergo massive refinements during postnatal development. In the developing cerebellum, the climbing fiber (CF) to Purkinje cell (PC) network is drastically reshaped by eliminating early-formed redundant CF to PC synapses. To investigate the impact of CF network refinement on PC population activity during postnatal development, we monitored spontaneous CF responses in neighboring PCs and the activity of populations of nearby CF terminals using in vivo two-photon calcium imaging. Population activity is highly synchronized in newborn mice, and the degree of synchrony gradually declines during the first postnatal week in PCs and, to a lesser extent, in CF terminals. Knockout mice lacking P/Q-type voltage gated calcium channel or glutamate receptor delta2, in which CF network refinement is severely impaired, exhibit an abnormally high level of synchrony in PC population activity. These results suggest that CF network refinement is a structural basis for developmental desynchronization and maturation of PC population activity. PMID- 29166600 TI - Dopamine Receptor DAMB Signals via Gq to Mediate Forgetting in Drosophila. AB - Prior studies have shown that aversive olfactory memory is acquired by dopamine acting on a specific receptor, dDA1, expressed by mushroom body neurons. Active forgetting is mediated by dopamine acting on another receptor, Damb, expressed by the same neurons. Surprisingly, prior studies have shown that both receptors stimulate cyclic AMP (cAMP) accumulation, presenting an enigma of how mushroom body neurons distinguish between acquisition and forgetting signals. Here, we surveyed the spectrum of G protein coupling of dDA1 and Damb, and we confirmed that both receptors can couple to Gs to stimulate cAMP synthesis. However, the Damb receptor uniquely activates Gq to mobilize Ca2+ signaling with greater efficiency and dopamine sensitivity. The knockdown of Galphaq with RNAi in the mushroom bodies inhibits forgetting but has no effect on acquisition. Our findings identify a Damb/Gq-signaling pathway that stimulates forgetting and resolves the opposing effects of dopamine on acquisition and forgetting. PMID- 29166601 TI - Triple Function of Synaptotagmin 7 Ensures Efficiency of High-Frequency Transmission at Central GABAergic Synapses. AB - Synaptotagmin 7 (Syt7) is thought to be a Ca2+ sensor that mediates asynchronous transmitter release and facilitation at synapses. However, Syt7 is strongly expressed in fast-spiking, parvalbumin-expressing GABAergic interneurons, and the output synapses of these neurons produce only minimal asynchronous release and show depression rather than facilitation. To resolve this apparent contradiction, we examined the effects of genetic elimination of Syt7 on synaptic transmission at the GABAergic basket cell (BC)-Purkinje cell (PC) synapse in cerebellum. Our results indicate that at the BC-PC synapse, Syt7 contributes to asynchronous release, pool replenishment, and facilitation. In combination, these three effects ensure efficient transmitter release during high-frequency activity and guarantee frequency independence of inhibition. Our results identify a distinct function of Syt7: ensuring the efficiency of high-frequency inhibitory synaptic transmission. PMID- 29166602 TI - Mucus Detachment by Host Metalloprotease Meprin beta Requires Shedding of Its Inactive Pro-form, which Is Abrogated by the Pathogenic Protease RgpB. AB - The host metalloprotease meprin beta is required for mucin 2 (MUC2) cleavage, which drives intestinal mucus detachment and prevents bacterial overgrowth. To gain access to the cleavage site in MUC2, meprin beta must be proteolytically shed from epithelial cells. Hence, regulation of meprin beta shedding and activation is important for physiological and pathophysiological conditions. Here, we demonstrate that meprin beta activation and shedding are mutually exclusive events. Employing ex vivo small intestinal organoid and cell culture experiments, we found that ADAM-mediated shedding is restricted to the inactive pro-form of meprin beta and is completely inhibited upon its conversion to the active form at the cell surface. This strict regulation of meprin beta activity can be overridden by pathogens, as demonstrated for the bacterial protease Arg gingipain (RgpB). This secreted cysteine protease potently converts membrane bound meprin beta into its active form, impairing meprin beta shedding and its function as a mucus-detaching protease. PMID- 29166603 TI - Caveolin1 Is Required for Th1 Cell Infiltration, but Not Tight Junction Remodeling, at the Blood-Brain Barrier in Autoimmune Neuroinflammation. AB - Lymphocytes cross vascular boundaries via either disrupted tight junctions (TJs) or caveolae to induce tissue inflammation. In the CNS, Th17 lymphocytes cross the blood-brain barrier (BBB) before Th1 cells; yet this differential crossing is poorly understood. We have used intravital two-photon imaging of the spinal cord in wild-type and caveolae-deficient mice with fluorescently labeled endothelial tight junctions to determine how tight junction remodeling and caveolae regulate CNS entry of lymphocytes during the experimental autoimmune encephalomyelitis (EAE) model for multiple sclerosis. We find that dynamic tight junction remodeling occurs early in EAE but does not depend upon caveolar transport. Moreover, Th1, but not Th17, lymphocytes are significantly reduced in the inflamed CNS of mice lacking caveolae. Therefore, tight junction remodeling facilitates Th17 migration across the BBB, whereas caveolae promote Th1 entry into the CNS. Moreover, therapies that target both tight junction degradation and caveolar transcytosis may limit lymphocyte infiltration during inflammation. PMID- 29166604 TI - Capture of Dense Core Vesicles at Synapses by JNK-Dependent Phosphorylation of Synaptotagmin-4. AB - Delivery of neurotrophins and neuropeptides via long-range trafficking of dense core vesicles (DCVs) from the cell soma to nerve terminals is essential for synapse modulation and circuit function. But the mechanism by which transiting DCVs are captured at specific sites is unknown. Here, we discovered that Synaptotagmin-4 (Syt4) regulates the capture and spatial distribution of DCVs in hippocampal neurons. We found that DCVs are highly mobile and undergo long-range translocation but switch directions only at the distal ends of axons, revealing a circular trafficking pattern. Phosphorylation of serine 135 of Syt4 by JNK steers DCV trafficking by destabilizing Syt4-Kif1A interaction, leading to a transition from microtubule-dependent DCV trafficking to capture at en passant presynaptic boutons by actin. Furthermore, neuronal activity increased DCV capture via JNK dependent phosphorylation of the S135 site of Syt4. Our data reveal a mechanism that ensures rapid, site-specific delivery of DCVs to synapses. PMID- 29166605 TI - L-Type Voltage-Gated Ca2+ Channels Regulate Synaptic-Activity-Triggered Recycling Endosome Fusion in Neuronal Dendrites. AB - The repertoire and abundance of proteins displayed on the surface of neuronal dendrites are tuned by regulated fusion of recycling endosomes (REs) with the dendritic plasma membrane. While this process is critical for neuronal function and plasticity, how synaptic activity drives RE fusion remains unexplored. We demonstrate a multistep fusion mechanism that requires Ca2+ from distinct sources. NMDA receptor Ca2+ initiates RE fusion with the plasma membrane, while L type voltage-gated Ca2+ channels (L-VGCCs) regulate whether fused REs collapse into the membrane or reform without transferring their cargo to the cell surface. Accordingly, NMDA receptor activation triggered AMPA-type glutamate receptor trafficking to the dendritic surface in an L-VGCC-dependent manner. Conversely, potentiating L-VGCCs enhanced AMPA receptor surface expression only when NMDA receptors were also active. Thus L-VGCCs play a role in tuning activity-triggered surface expression of key synaptic proteins by gating the mode of RE fusion. PMID- 29166606 TI - SUMOylation Promotes Nuclear Import and Stabilization of Polo-like Kinase 1 to Support Its Mitotic Function. AB - As a pivotal mitotic regulator, polo-like kinase 1 (PLK1) is under highly coordinated and multi-layered regulation. However, the pathways that control PLK1's activity and function have just begun to be elucidated. PLK1 has recently been shown to be functionally modulated by post-translational modifications (PTMs), including phosphorylation and ubiquitination. Herein, we report that SUMOylation plays an essential role in regulating PLK1's mitotic function. We found that Ubc9 was recruited to PLK1 upon initial phosphorylation and activation by CDK1/cyclin B. By in vivo and in vitro SUMOylation assays, PLK1 was identified as a physiologically relevant small ubiquitin-related modifier (SUMO)-targeted protein, preferentially modified by SUMO-1. We further showed that K492 on PLK1 is essential for SUMOylation. SUMOylation causes PLK1's nuclear import and significantly increases its protein stability, both of which are critical for normal mitotic progression and genomic integrity. Our findings suggest that SUMOylation is an important regulatory mechanism governing PLK1's mitotic function. PMID- 29166607 TI - Kdm2b Regulates Somatic Reprogramming through Variant PRC1 Complex-Dependent Function. AB - Polycomb repressive complex 1 (PRC1) plays essential roles in cell-fate determination. Recent studies have found that the composition of mammalian PRC1 is particularly varied and complex; however, little is known about the functional consequences of these variant PRC1 complexes on cell-fate determination. Here, we show that Kdm2b promotes Oct4-induced somatic reprogramming through recruitment of a variant PRC1 complex (PRC1.1) to CpG islands (CGIs). Furthermore, we find that bone morphogenetic protein (BMP) represses Oct4/Kdm2b-induced somatic reprogramming selectively. Mechanistically, BMP-SMAD pathway attenuates PRC1.1 occupation and H2AK119 ubiquitination at genes linked to development, resulting in the expression of mesendodermal factors such as Sox17 and a consequent suppression of somatic reprogramming. These observations reveal that PRC1.1 participates in the establishment of pluripotency and identify BMP4 signaling as a modulator of PRC1.1 function. PMID- 29166608 TI - S-Nitrosylation of PINK1 Attenuates PINK1/Parkin-Dependent Mitophagy in hiPSC Based Parkinson's Disease Models. AB - Mutations in PARK6 (PINK1) and PARK2 (Parkin) are linked to rare familial cases of Parkinson's disease (PD). Mutations in these genes result in pathological dysregulation of mitophagy, contributing to neurodegeneration. Here, we report that environmental factors causing a specific posttranslational modification on PINK1 can mimic these genetic mutations. We describe a molecular mechanism for impairment of mitophagy via formation of S-nitrosylated PINK1 (SNO-PINK1). Mitochondrial insults simulating age- or environmental-related stress lead to increased SNO-PINK1, inhibiting its kinase activity. SNO-PINK1 decreases Parkin translocation to mitochondrial membranes, disrupting mitophagy in cell lines and human-iPSC-derived neurons. We find levels of SNO-PINK1 in brains of alpha synuclein transgenic PD mice similar to those in cell-based models, indicating the pathophysiological relevance of our findings. Importantly, SNO-PINK1-mediated deficits in mitophagy contribute to neuronal cell death. These results reveal a direct molecular link between nitrosative stress, SNO-PINK1 formation, and mitophagic dysfunction that contributes to the pathogenesis of PD. PMID- 29166609 TI - GPR56/ADGRG1 Inhibits Mesenchymal Differentiation and Radioresistance in Glioblastoma. AB - A mesenchymal transition occurs both during the natural evolution of glioblastoma (GBM) and in response to therapy. Here, we report that the adhesion G-protein coupled receptor, GPR56/ADGRG1, inhibits GBM mesenchymal differentiation and radioresistance. GPR56 is enriched in proneural and classical GBMs and is lost during their transition toward a mesenchymal subtype. GPR56 loss of function promotes mesenchymal differentiation and radioresistance of glioma initiating cells both in vitro and in vivo. Accordingly, a low GPR56-associated signature is prognostic of a poor outcome in GBM patients even within non-G-CIMP GBMs. Mechanistically, we reveal GPR56 as an inhibitor of the nuclear factor kappa B (NF-kappaB) signaling pathway, thereby providing the rationale by which this receptor prevents mesenchymal differentiation and radioresistance. A pan-cancer analysis suggests that GPR56 might be an inhibitor of the mesenchymal transition across multiple tumor types beyond GBM. PMID- 29166610 TI - CISD2 Haploinsufficiency Disrupts Calcium Homeostasis, Causes Nonalcoholic Fatty Liver Disease, and Promotes Hepatocellular Carcinoma. AB - CISD2 is located within the chromosome 4q region frequently deleted in hepatocellular carcinoma (HCC). Mice with Cisd2 heterozygous deficiency develop a phenotype similar to the clinical manifestation of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). Cisd2 haploinsufficiency causes a low incidence (20%) of spontaneous HCC and promotes HBV-associated and DEN-induced HCC; conversely, 2-fold overexpression of Cisd2 suppresses HCC in these models. Mechanistically, Cisd2 interacts with Serca2b and mediates its Ca2+ pump activity via modulation of Serca2b oxidative modification, which regulates ER Ca2+ uptake and maintains intracellular Ca2+ homeostasis in the hepatocyte. CISD2 haploinsufficiency disrupts calcium homeostasis, causing ER stress and subsequent NAFLD and NASH. Hemizygous deletion and decreased expression of CISD2 are detectable in a substantial fraction of human HCC specimens. These findings substantiate CISD2 as a haploinsufficient tumor suppressor and highlights Cisd2 as a drug target when developing therapies to treat NAFLD/NASH and prevent HCC. PMID- 29166611 TI - CCR5 Directs the Mobilization of CD11b+Gr1+Ly6Clow Polymorphonuclear Myeloid Cells from the Bone Marrow to the Blood to Support Tumor Development. AB - Cells of hematopoietic origin can be subdivided into cells of the lymphoid lineage and those of the myeloid lineage, among which are myeloid-derived suppressor cells (MDSCs). The MDSCs can be further divided into CD11b+Ly6G-Ly6Chi monocytic (Mo) MDSCs and CD11b+Ly6G+Ly6Clow polymorphonuclear (PMN) MDSCs. Both subtypes support tumor growth and suppress anti-tumor immunity. Their accumulation at the tumor site includes mobilization from the bone marrow to the blood followed by colonization at the tumor site. The present study examines the mechanism by which PMN-MDSCs are mobilized from the BM to the blood to later accumulate at the tumor site. We show that the chemokine receptor CCR5 is a key driver of this event. We also show that, beyond chemoattraction, the interaction between CCR5 and its ligands promotes the proliferation of CCR5+ PMN-MDSCs at the BM and, later, potentiates their immune-suppressive activities at the tumor site in part by inducing arginase-1. PMID- 29166612 TI - Impediment of Replication Forks by Long Non-coding RNA Provokes Chromosomal Rearrangements by Error-Prone Restart. AB - Naturally stalled replication forks are considered to cause structurally abnormal chromosomes in tumor cells. However, underlying mechanisms remain speculative, as capturing naturally stalled forks has been a challenge. Here, we captured naturally stalled forks in tumor cells and delineated molecular processes underlying the structural evolution of circular mini-chromosomes (double-minute chromosomes; DMs). Replication forks stalled on the DM by the co-directional collision with the transcription machinery for long non-coding RNA. RPA, BRCA2, and DNA polymerase eta (Poleta) were recruited to the stalled forks. The recruitment of Poleta was critical for replication to continue, as Poleta knockdown resulted in DM loss. Rescued stalled forks were error-prone and switched replication templates repeatedly to create complex fusions of multiple short genomic segments. In mice, such complex fusions circularized the genomic region surrounding MYC to create a DM during tumorigenesis. Our results define a molecular path that guides stalled replication forks to complex chromosomal rearrangements. PMID- 29166613 TI - Niche Cadherins Control the Quiescence-to-Activation Transition in Muscle Stem Cells. AB - Many adult stem cells display prolonged quiescence, promoted by cues from their niche. Upon tissue damage, a coordinated transition to the activated state is required because non-physiological breaks in quiescence often lead to stem cell depletion and impaired regeneration. Here, we identify cadherin-mediated adhesion and signaling between muscle stem cells (satellite cells [SCs]) and their myofiber niche as a mechanism that orchestrates the quiescence-to-activation transition. Conditional removal of N-cadherin and M-cadherin in mice leads to a break in SC quiescence, with long-term expansion of a regeneration-proficient SC pool. These SCs have an incomplete disruption of the myofiber-SC adhesive junction and maintain niche residence and cell polarity, yet show properties of SCs in a state of transition from quiescence toward full activation. Among these is nuclear localization of beta-catenin, which is necessary for this phenotype. Injury-induced perturbation of niche adhesive junctions is therefore a likely first step in the quiescence-to-activation transition. PMID- 29166614 TI - Critical Modulation of Hematopoietic Lineage Fate by Hepatic Leukemia Factor. AB - A gradual restriction in lineage potential of multipotent stem/progenitor cells is a hallmark of adult hematopoiesis, but the underlying molecular events governing these processes remain incompletely understood. Here, we identified robust expression of the leukemia-associated transcription factor hepatic leukemia factor (Hlf) in normal multipotent hematopoietic progenitors, which was rapidly downregulated upon differentiation. Interference with its normal downregulation revealed Hlf as a strong negative regulator of lymphoid development, while remaining compatible with myeloid fates. Reciprocally, we observed rapid lymphoid commitment upon reduced Hlf activity. The arising phenotypes resulted from Hlf binding to active enhancers of myeloid-competent cells, transcriptional induction of myeloid, and ablation of lymphoid gene programs, with Hlf induction of nuclear factor I C (Nfic) as a functionally relevant target gene. Thereby, our studies establish Hlf as a key regulator of the earliest lineage-commitment events at the transition from multipotency to lineage-restricted progeny, with implications for both normal and malignant hematopoiesis. PMID- 29166615 TI - Olfactory-Experience- and Developmental-Stage-Dependent Control of CPEB4 Regulates c-Fos mRNA Translation for Granule Cell Survival. AB - Mammalian olfactory bulbs (OBs) require continuous replenishment of interneurons (mainly granule cells [GCs]) to support local circuits throughout life. Two spatiotemporally distinct waves of postnatal neurogenesis contribute to expanding and maintaining the GC pool. Although neonate-born GCs have a higher survival rate than adult-born GCs, the molecular mechanism underlying this survival remains unclear. Here, we find that cytoplasmic polyadenylation element-binding protein 4 (CPEB4) acts as a survival factor exclusively for early postnatal GCs. In mice, during the first 2 postnatal weeks, olfactory experience initiated CPEB4 activated c-Fos mRNA translation. In CPEB4-knockout mice, c-FOS insufficiency reduced neurotrophic signaling to impair GC survival and cause OB hypoplasia. Both cyclic AMP responsive element binding protein (CREB)-dependent transcription and CPEB4-promoted translation support c-FOS expression early postnatal OBs but disengage in adult OBs. Activity-related c-FOS synthesis and GC survival are thus developmentally controlled by distinct molecular mechanisms to govern OB growth. PMID- 29166616 TI - The Aryl Hydrocarbon Receptor Preferentially Marks and Promotes Gut Regulatory T Cells. AB - The local environment may affect the development and function of tissue-resident T regulatory cells (Tregs), which are crucial for controlling inflammation. Although the aryl hydrocarbon receptor (Ahr), an environmental sensor, is expressed by Tregs, its role in Treg cell development and/or function remains elusive. Here, we generated mouse genetic models to ablate or activate Ahr expression specifically in Tregs. We showed that Ahr was expressed more abundantly by peripherally induced Tregs (pTregs) in the gut and that its expression was independent of microbiota. Ahr was important for Treg gut homing and function. Ahr inhibited pro-inflammatory cytokines produced by Tregs but was dispensable for Treg stability. Furthermore, Ahr-expressing Tregs had enhanced in vivo suppressive activity compared with Tregs lacking Ahr expression in a T cell transfer model of colitis. Our data suggest that Ahr signaling in Tregs may be important for gut immune homeostasis. PMID- 29166617 TI - Spatiotemporal Proteomic Profiling of Huntington's Disease Inclusions Reveals Widespread Loss of Protein Function. AB - Aggregation of polyglutamine-expanded huntingtin exon 1 (HttEx1) in Huntington's disease (HD) proceeds from soluble oligomers to late-stage inclusions. The nature of the aggregates and how they lead to neuronal dysfunction is not well understood. We employed mass spectrometry (MS)-based quantitative proteomics to dissect spatiotemporal mechanisms of neurodegeneration using the R6/2 mouse model of HD. Extensive remodeling of the soluble brain proteome correlated with insoluble aggregate formation during disease progression. In-depth and quantitative characterization of the aggregates uncovered an unprecedented complexity of several hundred proteins. Sequestration to aggregates depended on protein expression levels and sequence features such as low-complexity regions or coiled-coil domains. In a cell-based HD model, overexpression of a subset of the sequestered proteins in most cases rescued viability and reduced aggregate size. Our spatiotemporally resolved proteome resource of HD progression indicates that widespread loss of cellular protein function contributes to aggregate-mediated toxicity. PMID- 29166618 TI - iPSC-Based Compound Screening and In Vitro Trials Identify a Synergistic Anti amyloid beta Combination for Alzheimer's Disease. AB - In the process of drug development, in vitro studies do not always adequately predict human-specific drug responsiveness in clinical trials. Here, we applied the advantage of human iPSC-derived neurons, which offer human-specific drug responsiveness, to screen and evaluate therapeutic candidates for Alzheimer's disease (AD). Using AD patient neurons with nearly 100% purity from iPSCs, we established a robust and reproducible assay for amyloid beta peptide (Abeta), a pathogenic molecule in AD, and screened a pharmaceutical compound library. We acquired 27 Abeta-lowering screen hits, prioritized hits by chemical structure based clustering, and selected 6 leading compounds. Next, to maximize the anti Abeta effect, we selected a synergistic combination of bromocriptine, cromolyn, and topiramate as an anti-Abeta cocktail. Finally, using neurons from familial and sporadic AD patients, we found that the cocktail showed a significant and potent anti-Abeta effect on patient cells. This human iPSC-based platform promises to be useful for AD drug development. PMID- 29166619 TI - Extensive Homeostatic T Cell Phenotypic Variation within the Collaborative Cross. AB - The Collaborative Cross (CC) is a panel of reproducible recombinant inbred mouse strains with high levels of standing genetic variation, affording an unprecedented opportunity to perform experiments in a small animal model containing controlled genetic diversity while allowing for genetic replicates. Here, we advance the utility of this unique mouse resource for immunology research because it allows for both examination and genetic dissection of mechanisms behind adaptive immune states in mice with distinct and defined genetic makeups. This approach is based on quantitative trait locus mapping: identifying genetically variant genome regions associated with phenotypic variance in traits of interest. Furthermore, the CC can be utilized for mouse model development; distinct strains have unique immunophenotypes and immune properties, making them suitable for research on particular diseases and infections. Here, we describe variations in cellular immune phenotypes across F1 crosses of CC strains and reveal quantitative trait loci responsible for several immune phenotypes.

AB - PARP1 plays a critical role in regulating many biological processes linked to cellular stress responses. Although DNA strand breaks are potent stimuli of PARP1 enzymatic activity, the context-dependent mechanism regulating PARP1 activation and signaling is poorly understood. We performed global characterization of the PARP1-dependent, Asp/Glu-ADP-ribosylated proteome in a panel of cell lines originating from benign breast epithelial cells, as well as common subtypes of breast cancer. From these analyses, we identified 503 specific ADP-ribosylation sites on 322 proteins. Despite similar expression levels, PARP1 is differentially activated in these cell lines under genotoxic conditions, which generates signaling outputs with substantial heterogeneity. By comparing protein abundances and ADP-ribosylation levels, we could dissect cell-specific PARP1 targets that are driven by unique expression patterns versus cell-specific regulatory mechanisms of PARylation. Intriguingly, PARP1 modifies many proteins in a cell specific manner, including those involved in transcriptional regulation, mRNA metabolism, and protein translation. PMID- 29166621 TI - Lifestyle transitions and adaptive pathogenesis of Pseudomonas aeruginosa. AB - Pseudomonas aeruginosa acute and chronic infections are of great concern to human health, especially in hospital settings. It is currently assumed that P. aeruginosa has two antagonistic pathogenic strategies that parallel two different lifestyles; free-living cells are predominantly cytotoxic and induce an acute inflammatory reaction, while biofilm-forming communities cause refractory chronic infections. Recent findings suggest that the planktonic-to-sessile transition is a complex, reversible and overall dynamic differentiation process. Here, we examine how the Gac/Rsm regulatory cascade, a key player in this lifestyle switch, endows P. aeruginosa with both a permissive lifecycle in nature and flexible virulence strategy during infection. PMID- 29166622 TI - Morphological characteristics and variations of the human quadratus plantae muscle. AB - The quadratus plantae (QP) is a highly variable structure. A number of partly inexact descriptions of this entity have been provided in textbooks of anatomy. Although several authors have examined the QP, its exact site of origin and type of insertion have hitherto not been specified. The aim of this study has been to provide detailed qualitative and quantitative data about the number of heads, points of origin, and type of insertion of the QP. The QP in both feet of 50 formalin-fixed specimens of body donors (25 men and women) were analyzed by gross anatomical dissection. It was composed of one (34%), two (57%) or three heads (9%). The latter condition was observed only in men. The lateral head was absent in 31 feet, and the medial head only in one right foot of a man. The medial head arose, amongst others, in 100% of the examined cases from the medial calcaneal surface, in 93% from the long plantar ligament and in 80% from the plantar calcaneocuboid ligament. The lateral head arose, amongst others, from the long plantar ligament in 90%, and from the lateral process of the calcaneal tuberosity in 64% of the examined feet. The type of insertion was always a mixture of at least two of three types; i.e. muscular (84%), tendinous (89%) and aponeurotic (45%). As additional findings, the flexor digitorum accessorius longus (FDAL) and the peroneocalcaneus internus (PCI) were observed in 12% of all individuals and in 20% of men. The present investigation revealed that the QP may be classified according to the number of heads, but no classification can be given for its points of origin or type of insertion. The present data are mandatory for anatomical and surgical practice and will hopefully lead to further imaging and biomechanical studies.

AB - Drawbacks and limitations of recently available therapies to hepatocellular cancer (HCC) devoted the scientist to focus on emerging new strategies. ZnO nanoparticles (ZnONPs) based chemotherapeutics has been emanating as a promising approach to maximize therapeutic synergy facilitating the discovery of novel multitargeted combinations. In the present study we conjugated ZnONPs with ferulic acid (ZnONPs-FAC) characterized by computational, spectroscopic and microscopic techniques. In vitro anticancer potential has been evaluated by assessing cell viability, morphology, ROS generation, mitochondrial membrane permeability, comet assay, immunofluorescent staining of 8-OHdG, Ki67 and gamma H2AX, cell cycle analysis and western blot analysis and in vivo anticancer potential against DEN induced HCC was analyzed by histopathological and immunohistochemical methods. The results revealed that ZnONPs-FAC induces cell death through apoptosis and can suppress the DEN-induced HCC. Our study documents therapeutic potential of nanoparticle conjugated with phytochemicals, suggesting a new platform for combinatorial chemotherapy. PMID- 29166624 TI - Impact of processing methods on the dissolution of artemether from two non ordered mesoporous silicas. AB - Poor aqueous solubility is often linked with a poor dissolution rate and ultimately, limited bioavailability of pharmaceutical compounds. This study describes the application of mesoporous materials (Syloid 244 and Syloid AL1) in improving the dissolution rate of a drug with poor aqueous solubility, namely artemether, utilising different processing methods including physical mixing, co grinding and solid dispersions prepared by solvent evaporation and the lyophilisation technique. The prepared formulations were extensively characterised for their solid-state properties and the drug release attributes were studied. Differential scanning calorimetry and X-ray diffraction confirmed conversion of crystalline artemether into a disordered and amorphous form, whilst no intermolecular interactions were detected between artemether and silica. Both silica grades enhanced the dissolution rate of artemether in comparison with drug alone, for example from 17.43% (+/-0.87%) to 71.55% (+/-3.57%) after 120mins with lyophilisation and Syloid 244 at a 1:3 ratio. This enhancement was also dependant on the choice of processing method, for example, co-ground and lyophilised formulations prepared with Syloid 244 at 1:3 ratio produced the most extensive dissolution, thus endorsing the importance of materials as well as choice of formulation method. PMID- 29166625 TI - Ambient surface mass spectrometry-ion mobility spectrometry of intact proteins. AB - Ambient surface mass spectrometry encompasses a broad range of sampling and ionization techniques. To date, only a small subset of these, based on liquid microjunction extraction, have proven suitable for intact protein analysis from thin tissue sections. Liquid extraction surface analysis shows particular promise for this application. Recently, a range of ion mobility spectrometry approaches have been coupled with ambient mass spectrometry. Improvements in signal-to-noise ratios, decreased chemical noise and separation of molecular classes have been described for the analysis of various biological substrates. Similar benefits have been described for ambient mass spectrometry imaging studies. In this review, we discuss the application of ambient mass spectrometry and ion mobility spectrometry to the analysis of intact proteins, and discuss opportunities and challenges for the field. PMID- 29166626 TI - Non-covalent interactions between thio-caffeine derivatives and water-soluble porphyrin in ethanol-water environment. AB - To determine the binding interactions and ability to form the non-covalent systems, the association process between 5,10,15,20-tetrakis[4 (trimethylammonio)phenyl]-21H,23H-porphine tetra-p-tosylate (H2TTMePP) and a series of five structurally diverse thio-caffeine analogues has been studied in ethanol and ethanol-water solutions, analyzing its absorption and steady-state fluorescence spectra. The porphyrin fluorescence lifetimes in the systems studied were established as well. During the titration with thio-caffeine compounds the slight bathochromic effect and considerable hypochromicity of the porphyrin Soret band maximum can be noted. The fluorescence quenching effect observed for interactions in H2TTMePP - thio-caffeine derivative systems, as well as the order of binding and fluorescence quenching constants (of 105-103mol-1) suggest the existence of the mechanism of static quenching due to the formation of non covalent and non-fluorescent stacking complexes. In all the systems studied the phenomenon of the fractional accessibility of the fluorophore for the quencher was observed as well. Additionally, the specific binding interactions, due to the changes in reaction environment polarity, can be observed. It was found that thio caffeine compounds can quench the porphyrin fluorescence according to the structure of thio-substituent in caffeine molecule. The obtained results can be potentially useful from scientific, therapeutic or environmental points of view. PMID- 29166627 TI - 1,4-Dioxane pollution at contaminated groundwater sites in western Germany and its distribution within a TCE plume. AB - An effective and sensitive method for the analysis of 1,4-dioxane in water has been available since 2008 (EPA 522). This method is increasingly being applied to investigate the distribution of 1,4-dioxane in the aquatic environment. However, there is a need for more information about the possible occurrence of 1,4-dioxane in groundwater in Europe in general, and in Germany in particular, where virtually no data have been collected so far. The possible contamination of groundwater with 1,4-dioxane is of relevance to Germany because up to 70% of Germany's drinking water is obtained from groundwater and about 17% from river bank filtrate, which contains variable proportions of groundwater. The aim of the present study is to investigate selected and representative groundwater sites in Germany that have suspected occurrences of 1,4-dioxane. Five of the sites are well known for their volatile chlorinated hydrocarbon contamination, two sites have representative landfill leachate characteristics, and one site is negatively impacted by a detergent manufacturing plant. The presence of 1,4-dioxane was observed at each of these sites. Measured maximum concentration values ranged from 0.15MUg/L to 152MUg/L. An aquifer containing a trichloroethylene (TCE) plume with 1,4-dioxane as a co-contaminant was investigated in more detail. A perfect match was found between the concentrations of 1,4-dioxane and TCE in the vertical and horizontal distribution profiles. The results indicate the necessity for investigating groundwater contamination by 1,4-dioxane at sites with known 1,1,1 trichloroethane (TCA) and TCE contaminations, in landfill leachates, and at sites of detergent production. PMID- 29166628 TI - Biochar application for the remediation of heavy metal polluted land: A review of in situ field trials. AB - Polluted land is a global issue, especially for developing countries. It has been reported that soil amendment with biochar may reduce the bioavailability of a wide range of contaminants, including heavy metal(loids), potentially reclaiming contaminated soils for agricultural use. However, there have been only limited reports on the in situ application of biochar at the field scale. This review was devoted to providing preliminary scientific evidence from these field trials, based on a review of 29 publications involving field applications of biochar in 8 different countries. The data show that biochar's effectiveness in reducing the impacts of pollution depends on a myriad of factors in the field, including the application time period, site-specific factors (e.g. climate, biochar dosage rate, and mixing depth), biochar feedstock type, and biochar properties. The results of this review indicate that biochar application can potentially reduce contaminant bioavailability in the field; for instance, a significant decrease (control normalized mean value=0.55) in the Cd enrichment of rice crops was observed. It was found that the use of biochar may help increase crop yields on polluted land, and thus reduce the amount of mineral fertilizer used in the field. However, in order to maximize the benefits of biochar addition, farmers need to accept that the dosage rates of mineral fertilizers should be reduced. This review also revealed that the effectiveness of biochar in mitigating pollution may decrease with time due to ageing factors, such as leaching of biochar alkalinity. PMID- 29166632 TI - How Old Are You? It's on Your Face! PMID- 29166633 TI - Range Extension and Behavioural Observations of the Recently Described Sheth's Dwarf Lemur (Cheirogaleus shethi). AB - Sheth's dwarf lemur, Cheirogaleus shethi, is a small, recently discovered nocturnal primate endemic to northern Madagascar. Unlike many other nocturnal lemurs, C. shethi lives sympatrically with morphologically similar species of its cryptic genus, making it difficult for biologists to determine its population density and distribution. Here, we present new data and observations of this species. During a series of rapid biodiversity assessments in the SAVA region of north-eastern Madagascar, we observed C. shethi in 10 different sites, 9 of which were not previously known to harbour C. shethi populations. More significantly, 2 of these sites, in Analamanara, were situated approximately 20 km south of the previously known southern extremity of this species' distribution. This represents a large increase in the previously limited geographic range of this species. Moreover, our relatively high encounter rates at these sites suggest that C. shethi population densities may be high. We also observed C. shethi in human-altered (e.g., vanilla plantations) and non-forest, savannah environments, suggesting that this species can tolerate disturbed habitats. Our findings therefore provide important additional information on the distribution of C. shethi populations and highlight the necessity of further study for the conservation of this species. PMID- 29166634 TI - Sodium Prescription in the Prevention of Intradialytic Hypotension: New Insights into an Old Concept. AB - BACKGROUND: Sodium prescription in patients with intradialytic hypotension remains a challenge for the attending nephrologist, as it increases dialysate conductivity in hypotension-prone patients, thereby adding to dietary sodium levels. METHODS: New sodium prescription strategies are now available, including the use of a mathematical model to compute the sodium mass to be removed during dialysis as a physiological controller. RESULTS: This review describes the sodium load of patients with end-stage renal disease on chronic hemodialysis (HD) and discusses 2 strategies to remove excess sodium in patients prone to intradialytic hypotension, namely, Profiled HD and the hemodiafiltration Aequilibrium System. CONCLUSION: The Profiled HD and Aequilibrium System trial both proved effective in counteracting intradialytic hypotension. PMID- 29166635 TI - The Protean Neuropsychiatric and Vestibuloauditory Manifestations of Neurosarcoidosis. AB - BACKGROUND: A rare subset of sarcoidosis, neurosarcoidosis, is reported to occur in 5-7% of sarcoid patients and can manifest in a variety of ways. The most common are facial paralysis and optic neuritis, less commonly causing cochleovestibulopathy, blindness, anosmia, and other cranial nerve (CN) palsies. The sensory deficit may be severe and psychiatric symptoms may result from the effects of the disease or steroid treatment. Although MRI-compatible cochlear implants are now available, concerns about the feasibility of recoverable hearing with cochlear implantation in these patients as well as the practical difficulty of disease monitoring due to implant artifact must be considered. RESULTS: We present 3 recent cases from different institutions. The first is a 39-year-old man with a history of progressively worsening hearing loss, followed by visual loss, delusions, agitation, ataxia, and musical auditory hallucinations, diffuse leptomeningeal enhancement on MRI with a normal serum angiotensin-converting enzyme (ACE) level but elevated cerebrospinal fluid (CSF) ACE levels, suggesting neurosarcoidosis, was treated with corticosteroids, and underwent successful cochlear implantation. The second is a 36-year-old woman with rapid-onset horizontal diplopia, left mixed severe sensorineural hearing loss (SNHL) and tinnitus, diffuse leptomeningeal enhancement on MRI, and progressive palsy of the left CNs IV, VI, VII, IX, X and XI, with altered mental status requiring admission following high-dose intravenous corticosteroids. The third is a 15-year old boy who presented with sudden, bilateral, profound SNHL, recurrent headaches, and left facial weakness refractory to antivirals, ultimately diagnosed with neurosarcoidosis following an aborted cochlear implantation where diffuse inflammation was found, and histopathology revealed Schaumann bodies; he was treated with methotrexate and later underwent successful cochlear implantation. CONCLUSIONS: Neurosarcoidosis is an elusive diagnosis and can cause hearing loss and psychiatric symptoms. Cochlear implantation for patients with severe hearing loss should be considered once the diagnosis is confirmed, as it is possible to achieve a successful level of hearing. Psychiatric symptoms can manifest with the onset of neurosarcoidosis, result from CN deficits, or develop as a side effect from long-term, high-dose corticosteroids, and should be monitored carefully in patients with neurosarcoidosis. PMID- 29166636 TI - RegentK and Physiotherapy Support Knee Function after Anterior Cruciate Ligament Rupture without Surgery after 1 Year: A Randomized Controlled Trial. AB - BACKGROUND: Recent data have opened the debate on whether conservative treatment of anterior cruciate ligament (ACL) rupture might be an alternative treatment option to surgery. In a previous study, such a conservative treatment, i.e. 'Regenerative Therapy According to Mohammed Khalifa' (RegentK), had shown good effects over physiotherapy. METHODS: This was a randomized controlled trial assessing the efficacy of 1 session of RegentK compared to the myofascial mobilization technique (MMT), another type of intensive physiotherapy, in 20 patients with fresh ACL rupture during the previous 4 weeks. The International Knee Documentation Committee (IKDC) 2000 score was measured before, immediately after, and 3 months after treatment, and 1 year later; magnetic resonance imaging (MRI) data were taken before treatment and 1 year after treatment. RESULTS: Both groups were comparable at baseline. A repeated measures analysis of variance showed a strong effect of time (p < 0.0001; partial eta2 = 0.81) and no significant interaction or group effect. Both groups reached near full function after 1 year. The IKDC score was 90.9 (standard deviation (SD) 6.7; 95% confidence interval (CI) 86.2-95.6) for the RegentK group and 93.3 (SD 3.1; 95% CI 91.1-95.5) for the MMT group. CONCLUSION: One treatment session of enhanced MMT physiotherapy or RegentK can lead to nearly full function and thus recovery of a ruptured ACL after 1 year. PMID- 29166637 TI - Assessing Vessel Tone during Coronary Artery Spasm by Dual-Acquisition Multidetector Computed Tomography Angiography. AB - BACKGROUND: Diminished vascular tone is an established biomarker of heart damage. Little is known about the extent of coronary vessel tone (CVT) with spasm as assessed by dual-acquisition multidetector computed tomography angiography (MCTA) in patients with vasospastic angina (VSA). OBJECTIVE: We evaluated the CVT modulated by intravenous nitrate injection (INI) using MCTA imaging in VSA patients. METHODS: Twenty-one VSA patients (60 +/- 9 years; 76% males) who underwent initial MCTA (without morning vasodilation), followed by an intracoronary ergonovine provocation test were included. Within 3 days after the initial MCTA patients received INI followed by 28-vessel segment spasm analyzed by MCTA 3D software, applying the following formula as the definition of CVT index (CVTI): (CSAIV nitrate - CSAinitial/CSAIV nitrate) *100 %, where CSA is the cross-sectional area. RESULTS: Compared to the initial MCTA measures, the INI provocation resulted in the significant increase of average diameter and CSA at the spasm site (2.60 mm [2.11-3.16] vs. 1.42 mm [1.13-2.13]; 5.37 mm2 [3.67-7.54] vs. 1.62 mm2 [1.02-3.02]; p < 0.001). The CVTI at the spastic segments was higher than at the proximal reference segments (41.0% [21.8-52.3] vs. 18.8% [5.9-26.6] for CVTI diameter; 65.1% [38.6-77.0] vs. 33.9% [5.2-48.1] for CVTI CSA, respectively). To predict VSA, the cut-off value for CVTI diameter was 38.6% (AUC 0.777; 95% CI 0.653-0.901) and 62.5% (AUC 0.779; 95% CI 0.657-0.902) for CVTI CSA in a receiver-operating characteristic curve analysis, with 57.1% sensitivity and 92.9% specificity. CONCLUSIONS: This novel imaging technique for assessing CVT by dual-acquisition MCTA after applying INI provocation is suitable for the detection of coronary artery spasm in patients with VSA. PMID- 29166638 TI - Predictors of Surgical Outcomes of Traumatic Peripheral Nerve Injuries in Children: An Institutional Experience. AB - AIM: This study was undertaken to address the epidemiological characteristics, operative details, and surgical outcome of peripheral nerve injuries in children treated in a tertiary hospital in India (NIMHANS, Bangalore). MATERIALS AND METHODS: This is a retrospective study of epidemiology, operative findings, and surgical outcomes over the period of 2000-2016. Our series includes 102 children with peripheral nerve injuries of various causes. RESULTS: Intramuscular injections were the most common cause (52.9%), followed by entrapment (15.6%). The most common nerve involved was the sciatic nerve (54.9%), followed by the common peroneal nerve (13.7%), the ulnar nerve (10.8%), and the radial nerve (10.8%). Perineural adhesion was the most common intraoperative finding (74.5%), followed by a neuroma in continuity (14.7%) and gap (10.8%). Most of the children with peripheral adhesion underwent external and internal neurolysis (75.5%). Follow-up was available for 67 children. The median follow-up period was 7 months (range 3-36). The outcome was assessed according to MRC grading. Favorable functional improvement was noted in 76.1% of the children. Age less than 10 years (p = 0. 06), injury before 6 months (p = 0.03), and MRC motor grade (<3) (p = 0. 01) were positive predictive factors related to the final outcome. CONCLUSION: Early surgical intervention, age less than 10 years, and incomplete motor palsy were the best predictors of a superior functional outcome. This study can serve as a guide to determine the epidemiology, duration of intervention, and surgical outcome of traumatic peripheral nerve injuries in the pediatric population. PMID- 29166639 TI - APOBEC3A Expression in Penile Squamous Cell Carcinoma. AB - BACKGROUND: APOBECs (apolipoprotein B mRNA-editing catalytic polypeptides) are cytidine deaminases that have been implicated in the host defense against viruses by blocking viral replication. They have also been shown to play a role in genome hypermutation in several human cancers. An APOBEC3 hypermutation signature has been discovered in cervical cancer, which is intimately associated with infection by high-risk human papillomaviruses (HPVs). At the same time, HPV genomes themselves are subject to DNA editing by APOBECs. Similar to cervical cancer, a proportion of penile squamous cell carcinomas (SCCs) is etiologically driven by high-risk HPVs, but very little is known about the role of APOBECs in penile SCC development and progression. METHODS: A series of 34 penile SCCs was analyzed for the expression of APOBEC3A protein by immunohistochemistry. HPV genotyping was carried out using a bead-based multiplex hybridization assay preceded by BSGP5+6+ primer-based amplification. RESULTS: We found a frequent reduction of APOBEC3A protein expression in the invasive parts of the majority of HPV-negative penile SCCs. In contrast, the majority of HPV-positive penile SCCs retained APOBEC3A expression during malignant progression. CONCLUSION: Our results suggest that APOBEC3A expression is downregulated during progression towards invasiveness in HPV-negative penile SCC, but maintained in HPV-positive penile SCC. How high-risk HPV-infected tumor cells tolerate high APOBEC3A, which appears to exert tumor suppressive functions in HPV-negative penile SCCs, remains to be elucidated. PMID- 29166640 TI - Lactic Acid Bacteria from Andean Grain Amaranth: A Source of Vitamins and Functional Value Enzymes. AB - Amaranth is a rediscovered pseudocereal with high nutritional properties. Lactic acid fermentation can increase the functional and nutritional value of foods. The aims of this study were to isolate and evaluate the functionality of lactic acid bacteria (LAB) from amaranth. LAB strains (n = 29) isolated from amaranth sourdough and grains included Lactobacillus (L.) plantarum (n = 8), L. rhamnosus (n = 6), Enterococcus (E.) mundtii (n = 4), E. hermanniensis (n = 3), E. durans (n = 1), Enterococcus sp. (n = 1), Leuconostoc (Lc.) mesenteroides (n = 3), and Lc. mesenteroides subsp. mesenteroides (n = 3). Only 21% of the strains showed the ability to synthesize capsular exopolysaccharides or display ropiness and only 8 strains showed amylolytic activity. L. plantarum CRL 2106 and E. durans CRL 2122 showed the highest phytase activity, which is of importance for mineral bioavailability. L. plantarum CRL 2106 and CRL 2107 and Lc. mesenteroides subsp. mesenteroides CRL 2131 synthesized the highest concentrations of B2 and B9 vitamin (140-250 ng/mL). This study demonstrates the potential of LAB to improve the nutritional and functional values of pseudocereal-derived foods. PMID- 29166641 TI - Agrowastes as Feedstock for the Production of Endo-beta-Xylanase from Cohnella sp. Strain AR92. AB - Members of Cohnella sp. isolated from a variety of environments have been shown to be glycoside hydrolase producers. Nevertheless, most evaluations of members of this genus are limited to their taxonomic description. The strain AR92, previously identified as belonging to the genus Cohnella, formed a well-supported cluster with C. thailandensis and C. formosensis (>80% bootstrap confidence). Its growth and xylanase production were approached by using a mineral-based medium containing alkali-pretreated sugarcane bagasse as the main carbon source, which was assayed as a convenient source to produce biocatalysts potentially fitting its degradation. By means of a two-step statistical approach, the production of endoxylanase was moderately improved (20%). However, a far more significant improvement was observed (145%), by increasing the inoculum size and lowering the fermentation temperature to 25 degrees C, which is below the optimal growth temperature of the strain AR92 (37 degrees C). The xylanolytic preparation produced by Cohnella sp. AR92 contained mild temperature-active endoxylanase (identified as redundant GH10 family) for the main activity which resulted in xylobiose and xylo-oligosaccharides as the main products from birchwood xylan. PMID- 29166642 TI - Effect of Calcium-Infiltrated Hydroxyapatite Scaffolds on the Hematopoietic Fate of Human Umbilical Vein Endothelial Cells. AB - Foamed hydroxyapatite offers a three-dimensional scaffold for the development of bone constructs, mimicking perfectly the in vivo bone structure. In vivo, calcium release at the surface is assumed to provide a locally increased gradient supporting the maintenance of the hematopoietic stem cells niche. We fabricated hydroxyapatite scaffolds with high surface calcium concentration by infiltration, and used human umbilical vein endothelial cells (HUVECs) as a model to study the effects on hematopoietic lineage direction. HUVECs are umbilical vein-derived and thus possess progenitor characteristics, with a prospective potential to give rise to hematopoietic lineages. HUVECs were cultured for long term on three dimensional porous hydroxyapatite scaffolds, which were either infiltrated biphasic foams or untreated. Controls were cultured in two-dimensional dishes. The release of calcium into culture medium was determined, and cells were analyzed for typical hematopoietic and endothelial gene expressions, surface markers by flow cytometry, and hematopoietic potential using colony-forming unit assays. Our results indicate that the biphasic foams promoted a hematopoietic lineage direction of HUVECs, suggesting an improved in vivo-like scaffold for hematopoietic bone tissue engineering. PMID- 29166643 TI - Effects of L- and N-Type Ca Channel Blocker Cilnidipine on Changes in Heart Rate and QT Interval During Dialysis. AB - BACKGROUND/AIMS: Hemodialysis patients have poor prognosis due to increased prevalence of cardiovascular diseases. Treatment to suppress increases in sympathetic nerve activity and QT prolongation may have the potential to reduce the occurrence of these events. The L/N-type Calcium (Ca) channel blocker cilnidipine has unique inhibitory action to inhibit sympathetic nerve activity and in a canine model ameliorates QT prolongation. In this study, we investigated whether cilnidipine has inhibitory effects on heart rate, an index of sympathetic nerve activity, and QT prolongation in patients undergoing dialysis. METHODS: An L-type Ca channel blocker amlodipine was administered for 4 weeks followed by cilnidipine treatment for 4 weeks. On the last day of each period, heart rate and corrected QT interval were estimated and compared between the two periods. RESULTS: Cilnidipine showed greater suppression of heart rate during dialysis than did amlodipine. The corrected QT interval in one dialysis session was significantly increased, and 3 of 17 patients showed prominent QT prolongation during administration of amlodipine but not cilnidipine. CONCLUSION: These data suggested that cilnidipine may inhibit increases in heart rate and QT interval. Cilnidipine may have beneficial effects in reducing cardiovascular events, resulting from increased sympathetic nerve activity and lethal arrhythmias in hemodialysis patients. PMID- 29166644 TI - Cylindromatosis (CYLD), a Deubiquitinase, Attenuates Inflammatory Signaling Pathways by Activating Toll-Like Receptor 3 in Human Mesangial Cells. AB - BACKGROUND/AIMS: Cylindromatosis (CYLD), a deubiquitinase, negatively regulates nuclear factor-kappaB in various cells. However, its potential roles in glomerular inflammation remain unclear. Because the activation of the Toll-like receptor 3 (TLR3)/type I interferon (IFN) pathways plays a pivotal role in chronic kidney diseases (CKD), we examined the role of CYLD in the TLR3 signaling in cultured human mesangial cells (MCs). METHODS: We stimulated CYLD-silenced MCs with polyinosinic-polycytidylic acid (poly IC), a synthetic analogue of dsRNA, and studied representative TLR3/IFN-beta pathways (i.e., TLR3/IFN-beta/retinoic acid-inducible gene-I (RIG-I)/CCL5, and TLR3/IFN-beta/melanoma differentiation associated gene 5 (MDA5)/CXCL10 axes) using RT-PCR, western blotting, and ELISA. We also used immunofluorescence staining and microscopy to examine mesangial CYLD expression in biopsied specimens from patients with CKD. RESULTS: CYLD silencing resulted in an increase of poly IC-induced RIG-I and MDA5 protein levels and increased CCL5 and CXCL10 mRNA and protein expression, but unexpectedly decreased mRNA expressions of RIG-I and MDA5. Interestingly, CYLD silencing did not affect IFN-beta or the phosphorylated STAT1 (signal transducers and activator of transcription protein 1). CYLD was highly expressed in biopsied specimens from patients with proliferative lupus nephritis (LN). CONCLUSION: CYLD inhibits post transcriptional regulation of RIG-I and MDA5 expression following TLR3 activation in MCs. CYLD may be involved in the pathogenesis of CKD, especially pathogenesis of LN. PMID- 29166646 TI - Reconstruction of membrane current by deconvolution and its application to membrane capacitance measurements in cardiac myocytes. AB - Correct detection of membrane currents under whole-cell patch-clamp conditions is limited by the transfer function of a recording system. The low-pass output filter of a recording amplifier alters the time course of membrane current and causes errors in relevant descriptors. To solve these problems, we developed a practical procedure for reconstruction of the time course of membrane currents based on deconvolution of recorded currents in frequency domain. The procedure was tested on membrane capacitance estimates from current responses to step voltage pulses. The reconstructed current responses, in contrast to original current records, could be described exactly by an adequate impedance model of a recorded cell. The reconstruction allowed to increase the accuracy and reliability of membrane capacitance measurements in wide range of cell sizes and to suppress the cross-talk errors well below the noise. Moreover, it allowed resolving the instabilities in recording conditions arising from parasitic capacitance and seal resistance variation. Complex tests on hardware models, on simulated data sets, and on living cells confirmed robustness and reliability of the deconvolution procedure. The aptitude of the method was demonstrated in isolated rat cardiac myocytes by recording of spontaneous vesicular events, by discerning the formation of a fusion pore, and by revealing artefacts due to unstable seal resistance. PMID- 29166645 TI - Angiotensin II Infusion Does Not Cause Abdominal Aortic Aneurysms in Apolipoprotein E-Deficient Rats. AB - The apolipoprotein E-deficient (apoE-/-) mouse model has advanced our understanding of cardiovascular disease mechanisms and experimental therapeutics. This spontaneous model recapitulates aspects of human atherosclerosis, and allows for the development of dissecting abdominal aortic aneurysms (AAAs) when combined with angiotensin II. We characterized apoE-/- rats and hypothesized that, similar to mice, they would develop dissecting AAAs. We created rats with a 16-bp deletion of the apoE gene using transcription activator-like effector nucleases. We imaged the suprarenal aorta for 28 days after implantation of miniosmotic pumps that infuse angiotensin II (AngII, 200 ng/kg/min). Blood pressure (BP), serum lipids and lipoproteins, and histology were also analyzed. These rats did not develop pathological aortic dissection, but we did observe a decrease in circumferential cyclic strain, a rise in BP, and microstructural changes in the aortic medial layer. We also measured increased serum lipids with and without administration of a high-fat diet, but did not detect atherosclerotic plaques. Chronic infusion of AngII did not lead to the formation of dissecting AAAs or atherosclerosis in the rats used in this study. While reduced amounts of atherosclerosis may explain this resistance to dissecting aneurysms, further investigation is needed to fully characterize species-specific differences. PMID- 29166647 TI - The reciprocal relations between experiential avoidance, school stressor, and psychological stress response among Japanese adolescents. AB - The present study aimed to investigate the reciprocal relations between experiential avoidance, stressor, and psychological stress response (which consist of anger, depression, anxiety, helplessness, and physical complaints). In this study, 688 Japanese junior high school students (353 boys, 334 girls, 1 unidentified; mean age 13.28 years) completed three waves of questionnaires on experiential avoidance, stressor, and psychological stress response, with one week intervals between measurement waves. Results from cross-lagged panel analyses showed that experiential avoidance predicted subsequent stressor and psychological stress response. Furthermore, the stressor and psychological stress response influenced by prior experiential avoidance affected subsequent occurrence of experiential avoidance. The findings suggest that reciprocal relations exist among the variables, and that the interaction between experiential avoidance and psychological stress was possible in adolescents. PMID- 29166648 TI - Different response to hypoxia of adipose-derived multipotent cells from obese subjects with and without metabolic syndrome. AB - BACKGROUND/OBJECTIVES: Multiple studies suggest that hypoxia, together with inflammation, could be one of the phenomena involved in the onset and progression of obesity-related insulin resistance. In addition, dysfunction of adipose tissue in obese subjects with metabolic syndrome is associated with decreased angiogenesis. However, some subjects with a high body mass index do not develop metabolic abnormalities associated with obesity. The aim of the current study was to examine the neovascular properties of visceral adipose tissue-derived multipotent mesenchymal cells subjected to hypoxia (hypox-visASCs) from normal weight subjects (Nw) and obese patients with metabolic syndrome (MS) and without metabolic syndrome (NonMS). METHODS: This was a 2-year study to enroll subjects who underwent bariatric surgery or cholecystectomy. Eight patients who underwent either bariatric surgery or cholecystectomy (27 patients) participated in the study. Visceral adipose tissue samples from Nw, MS and NonMS subjects were processed by enzymatic digestion. VisASCs cultured under hypoxic conditions were characterized by tubule formation assay, ELISA, flow cytometry, migration rate, and qRT-PCR, and the effects of visASCs-conditioned medium on survival and endothelial cell tubule formation were evaluated. RESULTS: Hypox-visASCs from NonMS subjects showed a greater capacity for tubule formation than hypox-visASCs from Nw and MS subjects. The lower percentage of CD140b+/CD44+ and CD140b+/CD184+ cells observed in hypox-visASCs from NonMS subjects compared to MS subjects was accompanied not only by a lower migration rate from the chemotactic effects of stromal cell derived factor 1alpha, but also by lower levels of NOX5 mRNA expression. While the levels of monocyte chemoattractant protein 1 mRNA expressed by hypox-visASCs correlated positively with the body mass index and waist circumference of the subjects, the concentration of vascular endothelial growth factor present in hypox-visASC-conditioned culture medium decreased significantly with increasing plasma glucose. The survival rate and tubules formed by endothelial cells cultured in hypox-visASC-conditioned medium decreased significantly with increasing homeostasis model assessment to quantify insulin resistance. CONCLUSIONS: Our results suggest that hypox-visASCs from NonMS subjects could promote healthy adipose tissue expansion, while hypox-visASCs from MS subjects appear to contribute to the decreased angiogenic potential and increased inflammation underlying adipose tissue dysfunction in obesity. Our results emphasize the importance of taking into account not only the BMI but also the metabolic profile of the subjects during the implementation of ASCs-based therapy to promote neovascularization. PMID- 29166649 TI - Extended light exposure increases stem digestibility and biomass production of switchgrass. AB - Switchgrass is a photoperiod-sensitive energy grass suitable for growing in the marginal lands of China. We explored the effects of extended photoperiods of low irradiance light (7 MUmol.m-2.s-1, no effective photosynthesis) on the growth, the biomass dry weight, the biomass allocation, and, especially, the stem digestibility and cell wall characteristics of switchgrass. Two extended photoperiods (i.e., 18 and 24 h) were applied over Alamo. Extended light exposure (18 and 24 h) resulted in delayed heading and higher dry weights of vegetative organs (by 32.87 and 35.94%, respectively) at the expense of reducing the amount of sexual organs (by 40.05 and 50.87%, respectively). Compared to the control group (i.e., natural photoperiod), the yield of hexoses (% dry matter) in the stems after a direct enzymatic hydrolysis (DEH) treatment significantly increased (by 44.02 and 46.10%) for those groups irradiated during 18 and 24 h, respectively. Moreover, the yield of hexoses obtained via enzymatic hydrolysis increased after both basic (1% NaOH) and acid (1% H2SO4) pretreatments for the groups irradiated during 18 and 24 h. Additionally, low-irradiance light extension (LILE) significantly increased the content of non-structural carbohydrates (NSCs) while notably reducing the lignin content and the syringyl to guaiacyl (S/G) ratio. These structural changes were in part responsible for the observed improved stem digestibility. Remarkably, LILE significantly decreased the cellulose crystallinity index (CrI) of switchgrass by significantly increasing both the arabinose substitution degree in xylan and the content of ammonium oxalate-extractable uronic acids, both favoring cellulose digestibility. Despite this LILE technology is not applied to the cultivation of switchgrass on a large scale yet, we believe that the present work is important in that it reveals important relationships between extended day length irradiations and biomass production and quality. Additionally, this study paves the way for improving biomass production and digestibility via genetic modification of day length sensitive transcription factors or key structural genes in switchgrass leaves. PMID- 29166650 TI - Feeding-induced changes in allatostatin-A and short neuropeptide F in the antennal lobes affect odor-mediated host seeking in the yellow fever mosquito, Aedes aegypti. AB - Aedes aegypti is a model species in which the endogenous regulation of odor mediated host seeking behavior has received some attention. Sugar feeding and host seeking in female A. aegypti are transiently inhibited following a blood meal. This inhibition is partially mediated by short neuropeptide F (sNPF). The paired antennal lobes (ALs), as the first processing centers for olfactory information, has been shown to play a significant role in the neuropeptidergic regulation of odor-mediated behaviors in insects. The expression of sNPF, along with other peptides in the ALs of A. aegypti, indicate parallel neuromodulatory systems that may affect olfactory processing. To identify neuropeptides involved in regulating the odor-mediated host seeking behavior in A. aegypti, we use a semi-quantitative neuropeptidomic analysis of single ALs to analyze changes in the levels of five individual neuropeptides in response to different feeding regimes. Our results show that the level of sNPF-2, allatostatin-A-5 (AstA-5) and neuropeptide-like precursor-1-5 (NPLP-1-5), but not of tachykinin-related peptides and SIFamide (SIFa), in the AL of female mosquitoes, changes 24 h and 48 h post-blood meal, and are dependent on prior access to sugar. To assess the role of these neuropeptides in modulating host seeking behavior, when systemically injected individually, sNPF-2 and AstA-5 significantly reduced host seeking behavior. However, only the injection of the binary mixture of the two neuropeptides lead to a host seeking inhibition similar to that observed in blood fed females. We conclude that modulation of the odor mediated host seeking behavior of A. aegypti is likely regulated by a dual neuropeptidergic pathway acting in concert in the ALs. PMID- 29166652 TI - Do patients' faces influence General Practitioners' cancer suspicions? A test of automatic processing of sociodemographic information. AB - BACKGROUND: Delayed cancer diagnosis leads to poorer patient outcomes. During short consultations, General Practitioners (GPs) make quick decisions about likelihood of cancer. Patients' facial cues are processed rapidly and may influence diagnosis. AIM: To investigate whether patients' facial characteristics influence immediate perception of cancer risk by GPs. DESIGN AND SETTING: Web based binary forced choice experiment with GPs from Northeast Scotland. METHOD: GPs were presented with a series of pairs of face prototypes and asked to quickly select the patient more likely to have cancer. Faces were modified with respect to age, gender, and ethnicity. Choices were analysed using Chi-squared goodness of-fit statistics with Bonferroni corrections. RESULTS: Eighty-two GPs participated. GPs were significantly more likely to suspect cancer in older patients. Gender influenced GP cancer suspicion, but this was modified by age: the male face was chosen as more likely to have cancer than the female face for young (72% of GPs;95% CI 61.0-87.0) and middle-aged faces (65.9%; 95% CI 54.7 75.5); but 63.4% (95% CI 52.2-73.3) decided the older female was more likely to have cancer than the older male (p = 0.015). GPs were significantly more likely to suspect cancer in the young Caucasian male (65.9% (95% CI 54.7, 75.5)) compared to the young Asian male (p = 0.004). CONCLUSION: GPs' first impressions about cancer risk are influenced by patient age, gender, and ethnicity. Tackling GP cognitive biases could be a promising way of reducing cancer diagnostic delays, particularly for younger patients. PMID- 29166651 TI - Stiffness analysis of 3D spheroids using microtweezers. AB - We describe a novel mechanical characterization method that has directly measured the stiffness of cancer spheroids for the first time to our knowledge. Stiffness is known to be a key parameter that characterizes cancerous and normal cells. Atomic force microscopy or optical tweezers have been typically used for characterization of single cells with the measurable forces ranging from sub pN to a few hundred nN, which are not suitable for measurement of larger 3D cellular structures such as spheroids, whose mechanical characteristics have not been fully studied. Here, we developed microtweezers that measure forces from sub hundred nN to mN. The wide force range was achieved by the use of replaceable cantilevers fabricated from SU8, and brass. The chopstick-like motion of the two cantilevers facilitates easy handling of samples and microscopic observation for mechanical characterization. The cantilever bending was optically tracked to find the applied force and sample stiffness. The efficacy of the method was demonstrated through stiffness measurement of agarose pillars with known concentrations. Following the initial system evaluation with agarose, two cancerous (T47D and BT474) and one normal epithelial (MCF 10A) breast cell lines were used to conduct multi-cellular spheroid measurements to find Young's moduli of 230, 420 and 1250 Pa for BT474, T47D, and MCF 10A, respectively. The results showed that BT474 and T47D spheroids are six and three times softer than epithelial MCF10A spheroids, respectively. Our method successfully characterized samples with wide range of Young's modulus including agarose (25-100 kPa), spheroids of cancerous and non-malignant cells (190-200 MUm, 230-1250 Pa) and collagenase-treated spheroids (215 MUm, 130 Pa). PMID- 29166653 TI - Testing the applicability of a benthic foraminiferal-based transfer function for the reconstruction of paleowater depth changes in Rhodes (Greece) during the early Pleistocene. AB - We present paleo-water depth reconstructions for the Pefka E section deposited on the island of Rhodes (Greece) during the early Pleistocene. For these reconstructions, a transfer function (TF) using modern benthic foraminifera surface samples from the Adriatic and Western Mediterranean Seas has been developed. The TF model gives an overall predictive accuracy of ~50 m over a water depth range of ~1200 m. Two separate TF models for shallower and deeper water depth ranges indicate a good predictive accuracy of 9 m for shallower water depths (0-200 m) but far less accuracy of 130 m for deeper water depths (200-1200 m) due to uneven sampling along the water depth gradient. To test the robustness of the TF, we randomly selected modern samples to develop random TFs, showing that the model is robust for water depths between 20 and 850 m while greater water depths are underestimated. We applied the TF to the Pefka E fossil data set. The goodness-of-fit statistics showed that most fossil samples have a poor to extremely poor fit to water depth. We interpret this as a consequence of a lack of modern analogues for the fossil samples and removed all samples with extremely poor fit. To test the robustness and significance of the reconstructions, we compared them to reconstructions from an alternative TF model based on the modern analogue technique and applied the randomization TF test. We found our estimates to be robust and significant at the 95% confidence level, but we also observed that our estimates are strongly overprinted by orbital, precession-driven changes in paleo-productivity and corrected our estimates by filtering out the precession-related component. We compared our corrected record to reconstructions based on a modified plankton/benthos (P/B) ratio, excluding infaunal species, and to stable oxygen isotope data from the same section, as well as to paleo-water depth estimates for the Lindos Bay Formation of other sediment sections of Rhodes. These comparisons indicate that our orbital corrected reconstructions are reasonable and reflect major tectonic movements of Rhodes during the early Pleistocene. PMID- 29166654 TI - Therapeutic efficacy of equine botulism antitoxin in Rhesus macaques. AB - BACKGROUND: There are currently no licensed vaccines available for prevention of botulism in humans. The vaccination is not desirable due to expanding therapeutic indications of botulinum toxins. The only available specific treatment for botulism is antitoxin to remove circulating toxin, thus, preventing further neuronal damage. BAT(r) (Botulism Antitoxin Heptavalent (A, B, C, D, E, F, G) (Equine)) has been developed and its therapeutic efficacy evaluated against botulinum neurotoxin serotype A (BoNT/A) in Rhesus macaques. METHODS AND FINDINGS: In a post-exposure prophylaxis (PEP) study, animals were exposed to 4x LD50/kg of BoNT/A and administered intravenously with either BAT (1x or 0.1x scaled human dose), or placebo at 4 hours post-exposure. The animals were monitored for 14 days. For the therapeutic intervention studies, animals were exposed to a 1.7x LD50/kg of BoNT/A and treated intravenously with either placebo or BAT at a 1x scaled human dose at the onset of clinical signs. Animals were monitored on an hourly basis for 14 or 21 days. In the PEP study, all animals tolerated equine based antitoxin without any adverse clinical signs. A 100% survival was observed in groups treated with the BAT compared to 0% survival in those treated with the placebo (p<0.001, Fisher's exact test). BAT antitoxin prevented the development of signs of neurotoxicity of botulinum toxin. In a therapeutic study, treatment with the BAT at scaled 1x human dose after the onset of clinical signs significantly enhanced survival compared to the placebo (46.6% vs. 0%, p<0.0001, Fisher's exact test). Additionally, treatment with the BAT delayed the progression of signs (muscular weakness, respiratory distress, oral/nasal discharge) of toxin intoxication and reduced the severity of the disease. CONCLUSIONS: A single dose of BAT, when administered to symptomatic monkeys, resulted in a statistically significant survival benefit compared to the placebo. Additionally, BAT completely protected monkeys from the clinical signs of intoxication and subsequent death when administered as PEP treatment. These data in part supported the licensure of BAT under the Animal Rule in the United States by the Food and Drug Administration. PMID- 29166655 TI - How well do you know your mutation? Complex effects of genetic background on expressivity, complementation, and ordering of allelic effects. AB - For a given gene, different mutations influence organismal phenotypes to varying degrees. However, the expressivity of these variants not only depends on the DNA lesion associated with the mutation, but also on factors including the genetic background and rearing environment. The degree to which these factors influence related alleles, genes, or pathways similarly, and whether similar developmental mechanisms underlie variation in the expressivity of a single allele across conditions and among alleles is poorly understood. Besides their fundamental biological significance, these questions have important implications for the interpretation of functional genetic analyses, for example, if these factors alter the ordering of allelic series or patterns of complementation. We examined the impact of genetic background and rearing environment for a series of mutations spanning the range of phenotypic effects for both the scalloped and vestigial genes, which influence wing development in Drosophila melanogaster. Genetic background and rearing environment influenced the phenotypic outcome of mutations, including intra-genic interactions, particularly for mutations of moderate expressivity. We examined whether cellular correlates (such as cell proliferation during development) of these phenotypic effects matched the observed phenotypic outcome. While cell proliferation decreased with mutations of increasingly severe effects, surprisingly it did not co-vary strongly with the degree of background dependence. We discuss these findings and propose a phenomenological model to aid in understanding the biology of genes, and how this influences our interpretation of allelic effects in genetic analysis. PMID- 29166656 TI - Fragmentation modes and the evolution of life cycles. AB - Reproduction is a defining feature of living systems. To reproduce, aggregates of biological units (e.g., multicellular organisms or colonial bacteria) must fragment into smaller parts. Fragmentation modes in nature range from binary fission in bacteria to collective-level fragmentation and the production of unicellular propagules in multicellular organisms. Despite this apparent ubiquity, the adaptive significance of fragmentation modes has received little attention. Here, we develop a model in which groups arise from the division of single cells that do not separate but stay together until the moment of group fragmentation. We allow for all possible fragmentation patterns and calculate the population growth rate of each associated life cycle. Fragmentation modes that maximise growth rate comprise a restrictive set of patterns that include production of unicellular propagules and division into two similar size groups. Life cycles marked by single-cell bottlenecks maximise population growth rate under a wide range of conditions. This surprising result offers a new evolutionary explanation for the widespread occurrence of this mode of reproduction. All in all, our model provides a framework for exploring the adaptive significance of fragmentation modes and their associated life cycles. PMID- 29166657 TI - The effects of Kinesio Taping on the trajectory of the forelimb and the muscle activity of the Musculus brachiocephalicus and the Musculus extensor carpi radialis in horses. AB - BACKGROUND INFORMATION: The present study aimed to investigate the effects of Kinesio Taping on the trajectory of the forelimb and the muscle activity of the M. brachiocephalicus and the M. extensor carpi radialis in horses. 19 horses and ponies of different breeds (body weight: 496+/-117 kg), gender (8 mares, 10 geldings and 3 stallions) and ages (14.9+/-6.9 years old) were analysed without Kinesio Tape ("no tape"), with Kinesio Tape (muscle facilitation application on both muscles of both sides, "with tape") and immediately after Kinesio Taping ("post tape") through kinematic motion analysis and surface electromyography on a treadmill at the walk (speed: 1.5+/-0.1 m/s) and trot (speed: 3.1+/-0.3 m/s). RESULTS: The results of the surface electromyography (maximum muscle activity at the walk and trot) and the kinematic motion analysis (maximum stride length and maximum height of the forelimbs flight arc at the walk and trot) showed that there were no significant differences between "no tape", "with tape" and "post tape". CONCLUSION: To sum up, Kinesio Taping on the M. brachiocephalicus and the M. extensor carpi radialis does not affect (in a positive or negative manner) the trajectory of the forelimb or the muscle activity of the M. brachiocephalicus and the M. extensor carpi radialis in horses. PMID- 29166658 TI - Episodic future thinking reduces temporal discounting in healthy adolescents. AB - Episodic Future Thinking has proven efficient in reducing impulsive behavior in several adult populations. Whether it also has a beneficial impact on decision making in adolescents is not known. Here the impact of episodic future thinking on discounting behavior was investigated in a sample of healthy adolescents (n = 44, age range 13-16 years). Discounting behavior in trials including episodic future thinking was significantly less impulsive than in control trials (t = 2.74, p = .009, dz = .44). In a subsample we controlled for executive function, alcohol use and developmental measures. Neither executive function nor alcohol use but developmental measures explained variability in the effect of episodic future thinking. These findings reveal that episodic future thinking can improve adolescent decision making while the effect is to some degree modulated by developmental measures. PMID- 29166659 TI - Sex-specific influences of mtDNA mitotype and diet on mitochondrial functions and physiological traits in Drosophila melanogaster. AB - Here we determine the sex-specific influence of mtDNA type (mitotype) and diet on mitochondrial functions and physiology in two Drosophila melanogaster lines. In many species, males and females differ in aspects of their energy production. These sex-specific influences may be caused by differences in evolutionary history and physiological functions. We predicted the influence of mtDNA mutations should be stronger in males than females as a result of the organelle's maternal mode of inheritance in the majority of metazoans. In contrast, we predicted the influence of diet would be greater in females due to higher metabolic flexibility. We included four diets that differed in their protein: carbohydrate (P:C) ratios as they are the two-major energy-yielding macronutrients in the fly diet. We assayed four mitochondrial function traits (Complex I oxidative phosphorylation, reactive oxygen species production, superoxide dismutase activity, and mtDNA copy number) and four physiological traits (fecundity, longevity, lipid content, and starvation resistance). Traits were assayed at 11 d and 25 d of age. Consistent with predictions we observe that the mitotype influenced males more than females supporting the hypothesis of a sex-specific selective sieve in the mitochondrial genome caused by the maternal inheritance of mitochondria. Also, consistent with predictions, we found that the diet influenced females more than males. PMID- 29166660 TI - Great apes are sensitive to prior reliability of an informant in a gaze following task. AB - Social animals frequently rely on information from other individuals. This can be costly in case the other individual is mistaken or even deceptive. Human infants below 4 years of age show proficiency in their reliance on differently reliable informants. They can infer the reliability of an informant from few interactions and use that assessment in later interactions with the same informant in a different context. To explore whether great apes share that ability, in our study we confronted great apes with a reliable or unreliable informant in an object choice task, to see whether that would in a subsequent task affect their gaze following behaviour in response to the same informant. In our study, prior reliability of the informant and habituation during the gaze following task affected both great apes' automatic gaze following response and their more deliberate response of gaze following behind barriers. As habituation is very context specific, it is unlikely that habituation in the reliability task affected the gaze following task. Rather it seems that apes employ a reliability tracking strategy that results in a general avoidance of additional information from an unreliable informant. PMID- 29166661 TI - Ultraconserved elements (UCEs) resolve the phylogeny of Australasian smurf weevils. AB - Weevils (Curculionoidea) comprise one of the most diverse groups of organisms on earth. There is hardly a vascular plant or plant part without its own species of weevil feeding on it and weevil species diversity is greater than the number of fishes, birds, reptiles, amphibians and mammals combined. Here, we employ ultraconserved elements (UCEs) designed for beetles and a novel partitioning strategy of loci to help resolve phylogenetic relationships within the radiation of Australasian smurf-weevils (Eupholini). Despite being emblematic of the New Guinea fauna, no previous phylogenetic studies have been conducted on the Eupholini. In addition to a comprehensive collection of fresh specimens, we supplement our taxon sampling with museum specimens, and this study is the first target enrichment phylogenomic dataset incorporating beetle specimens from museum collections. We use both concatenated and species tree analyses to examine the relationships and taxonomy of this group. For species tree analyses we present a novel partitioning strategy to better model the molecular evolutionary process in UCEs. We found that the current taxonomy is problematic, largely grouping species on the basis of similar color patterns. Finally, our results show that most loci required multiple partitions for nucleotide rate substitution, suggesting that single partitions may not be the optimal partitioning strategy to accommodate rate heterogeneity for UCE loci. PMID- 29166662 TI - Detection of HBsAg mutants in the blood donor population of Pakistan. AB - BACKGROUND: Infection with the Hepatitis B virus (HBV) continues to be one of the leading healthcare issues in Pakistan, affecting over 6 million people. The existence of HBsAg mutants is well documented in many countries. In Pakistan, HBV screening in the majority of the blood banks is performed by Rapid Detection Devices or ELISA tests. These tests are designed to detect HBsAg, but may not detect the mutant HBsAg. Failure to detect the HBsAg mutant may result in the transmission of HBV infection from donor to recipient. Hence, there is a need to identify a HBsAg assay which can detect mutants in a country where simple and conventional HBsAg assays with varying sensitivity and specificity are used to detect HBV infections. MATERIAL AND METHODS: Three routinely used diagnostic tests (Rapid Detection Devices, ELISA and CLIA) for HBsAg were compared with the LIAISON(r) XL Murex HBsAg Quant Assay to determine the prevalence of HBV mutants in the Pakistani blood donor population. The samples of blood donors from different cities of Pakistan were collected. The testing was performed using SD Bioline rapid assay (n = 1500), ELISA (n = 1500), and Abbott ARCHITECT(r)CLIA system (n = 1500) at the centers where the donations were collected. All samples (n = 4500) were re-tested for comparative analysis on the LIAISON(r) XL Murex HBsAg Quant assay (DiaSorin S.p.A.). PCR testing was performed as a gold standard on all discordant samples. RESULTS: 119/4500 (2.64%) of the samples were positive for antibodies against HBsAg. The sensitivity of SD Bioline Rapid, GB HBsAg ELISA, Abbott ARCHITECT(r) and LIAISON(r) XL Murex HBsAg Quant assay was 17.24%, 43.75%, 90.91%and 100% respectively. The specificity of SD Bioline Rapid, GB HBsAg ELISA, Abbott ARCHITECT(r) and LIAISON(r) XL Murex HBsAg Quant Assay was 98.82%, 99.59%, 100% and 100%, respectively. CONCLUSION: LIAISON(r) XL Murex HBsAg Quant assay is a highly sensitive, specific and accurate screening assay for detecting wild type as well as mutant HBsAg. PMID- 29166663 TI - A general model for predicting the binding affinity of reversibly and irreversibly dimerized ligands. AB - Empirical data has shown that bivalent inhibitors can bind a given target protein significantly better than their monomeric counterparts. However, predicting the corresponding theoretical fold improvements has been challenging. The current work builds off the reacted-site probability approach to provide a straightforward baseline reference model for predicting fold-improvements in effective affinity of dimerized ligands over their monomeric counterparts. For the more familiar irreversibly linked bivalents, the model predicts a weak dependence on tether length and a scaling of the effective affinity with the 3/2 power of the monomer's affinity. For the previously untreated case of the emerging technology of reversibly linking dimers, the effective affinity is also significantly improved over the affinity of the non-dimerizing monomers. The model is related back to experimental quantities, such as EC50s, and the approaches to fully characterize the system given the assumptions of the model. Because of the predicted significant potency gains, both irreversibly and reversibly linked bivalent ligands offer the potential to be a disruptive technology in pharmaceutical research. PMID- 29166664 TI - Is there a reasonable excuse for not providing post-operative analgesia when using animal models of peripheral neuropathic pain for research purposes? AB - INTRODUCTION: The induction of neuropathic pain-like behaviors in rodents often requires surgical intervention. This engages acute nociceptive signaling events that contribute to pain and stress post-operatively that from a welfare perspective demands peri-operative analgesic treatment. However, a large number of researchers avoid providing such care based largely on anecdotal opinions that it might interfere with model pathophysiology in the longer term. OBJECTIVES: To investigate effects of various peri-operative analgesic regimens encapsulating different mechanisms and duration of action, on the development of post-operative stress/welfare and pain-like behaviors in the Spared Nerve Injury (SNI)-model of neuropathic pain. METHODS: Starting on the day of surgery, male Sprague-Dawley rats were administered either vehicle (s.c.), carprofen (5.0mg/kg, s.c.), buprenorphine (0.1mg/kg s.c. or 1.0mg/kg p.o. in Nutella(r)), lidocaine/bupivacaine mixture (local irrigation) or a combination of all analgesics, with coverage from a single administration, and up to 72 hours. Post operative stress and recovery were assessed using welfare parameters, bodyweight, food-consumption, and fecal corticosterone, and hindpaw mechanical allodynia was tested for assessing development of neuropathic pain for 28 days. RESULTS: None of the analgesic regimes compromised the development of mechanical allodynia. Unexpectedly, the combined treatment with 0.1mg/kg s.c. buprenorphine and carprofen for 72 hours and local irrigation with lidocaine/bupivacaine, caused severe adverse effects with peritonitis. This was not observed when the combination included a lower dose of buprenorphine (0.05mg/kg, s.c.), or when buprenorphine was administered alone (0.1mg/kg s.c. or 1.0mg/kg p.o.) for 72 hours. An elevated rate of wound dehiscence was observed especially in the combined treatment groups, underlining the need for balanced analgesia. Repeated buprenorphine injections had positive effects on body weight the first day after surgery, but depressive effects on food intake and body weight later during the first week. CONCLUSION: Post-operative analgesia does not appear to affect established neuropathic hypersensitivity outcome in the SNI model. PMID- 29166665 TI - Meditation experts try Virtual Reality Mindfulness: A pilot study evaluation of the feasibility and acceptability of Virtual Reality to facilitate mindfulness practice in people attending a Mindfulness conference. AB - Regular mindfulness practice benefits people both mentally and physically, but many populations who could benefit do not practice mindfulness. Virtual Reality (VR) is a new technology that helps capture participants' attention and gives users the illusion of "being there" in the 3D computer generated environment, facilitating sense of presence. By limiting distractions from the real world, increasing sense of presence and giving people an interesting place to go to practice mindfulness, Virtual Reality may facilitate mindfulness practice. Traditional Dialectical Behavioral Therapy (DBT(r)) mindfulness skills training was specifically designed for clinical treatment of people who have trouble focusing attention, however severe patients often show difficulties or lack of motivation to practice mindfulness during the training. The present pilot study explored whether a sample of mindfulness experts would find useful and recommend a new VR Dialectical Behavioral Therapy (DBT(r)) mindfulness skills training technique and whether they would show any benefit. Forty four participants attending a mindfulness conference put on an Oculus Rift DK2 Virtual Reality helmet and floated down a calm 3D computer generated virtual river while listening to digitized DBT(r) mindfulness skills training instructions. On subjective questionnaires completed by the participants before and after the VR DBT(r) mindfulness skills training session, participants reported increases/improvements in state of mindfulness, and reductions in negative emotional states. After VR, participants reported significantly less sadness, anger, and anxiety, and reported being significantly more relaxed. Participants reported a moderate to strong illusion of going inside the 3D computer generated world (i.e., moderate to high "presence" in VR) and showed high acceptance of VR as a technique to practice mindfulness. These results show encouraging preliminary evidence of the feasibility and acceptability of using VR to practice mindfulness based on clinical expert feedback. VR is a technology with potential to increase computerized dissemination of DBT(r) skills training modules. Future research is warranted. PMID- 29166666 TI - Evaluating the efficacy of an active compression brace on orthostatic cardiovascular responses. AB - Orthostatic intolerance, one of the principle causes of syncope, can occur secondary to concomitant venous pooling and enhanced capillary filtration. We aimed to evaluate a prototype portable calf active compression brace (ACB) designed to improve orthostatic haemodynamic control. Fourteen healthy volunteers participated in a randomized, placebo controlled, cross-over, double-blind study. Testing consisted of head-upright tilting and walking on a treadmill conducted on two consecutive days with a pair of ACBs wrapped around both calves. The ACB was actuated on one test day, but not on the other (placebo). Wearability, comfort, and ambulatory use of the ACB were assessed using questionnaires. The average calf pressure exerted by the ACB was 46.3+/-2.2 mmHg and the actuation pressure was 20.7+/-1.7 mmHg. When considering the differences between ACB actuation and placebo during tilt after supine rest there were trends for a larger stroke volume (+5.20+/-2.34%, p = 0.05) and lower heart rate (-5.12+/-2.41%, p = 0.06) with ACB actuation, with no effect on systolic arterial pressure (+4.86+/-3.41%, p = 0.18). The decrease in stroke volume after ten minutes of tilting was positively correlated with the height:calf circumference (r = 0.464; p = 0.029; n = 22; both conditions combined). The increase in heart rate after ten minutes of tilting was negatively correlated with the height:calf circumference (r = -0.485; p = 0.022; n = 22; both conditions combined) and was positively correlated with the average calf circumference (r = 0.539; p = 0.009; n = 22; both conditions combined). Participants reported good ACB wearability and comfort during ambulatory use. These data verify that the ACB increased stroke volume during tilting in healthy controls. Active calf compression garments may be a viable option for the management of orthostatic intolerance.

AB - Pseudomonas aeruginosa is a Gram-negative pathogen that can lead to severe infection associated with lung injury and high mortality. The interleukin (IL)-36 cytokines (IL-36alpha, IL-36beta and IL-36gamma) are newly described IL-1 like family cytokines that promote inflammatory response via binding to the IL-36 receptor (IL-36R). Here we investigated the functional role of IL-36 cytokines in the modulating of innate immune response against P. aeruginosa pulmonary infection. The intratracheal administration of flagellated cytotoxic P. aeruginosa (ATCC 19660) upregulated IL-36alpha and IL-36gamma, but not IL-36beta, in the lungs. IL-36alpha and IL-36gamma were expressed in pulmonary macrophages (PMs) and alveolar epithelial cells in response to P. aeruginosa in vitro. Mortality after bacterial challenge in IL-36 receptor deficient (IL-36R-/-) mice and IL-36gamma deficient (IL-36gamma-/-) mice, but not IL-36alpha deficient mice, was significantly lower than that of wild type mice. Decreased mortality in IL 36R-/- mice and IL-36gamma-/- mice was associated with reduction in bacterial burden in the alveolar space, bacterial dissemination, production of inflammatory cytokines and lung injury, without changes in lung leukocyte influx. Interestingly, IL-36gamma enhanced the production of prostaglandin E2 (PGE2) during P. aeruginosa infection in vivo and in vitro. Treatment of PMs with recombinant IL-36gamma resulted in impaired bacterial killing via PGE2 and its receptor; EP2. P. aeruginosa infected EP2 deficient mice or WT mice treated with a COX-2-specific inhibitor showed decreased bacterial burden and dissemination, but no change in lung injury. Finally, we observed an increase in IL-36gamma, but not IL-36alpha, in the airspace and plasma of patients with P. aeruginosa-induced acute respiratory distress syndrome. Thus, IL-36gamma and its receptor signal not only impaired bacterial clearance in a possible PGE2 dependent fashion but also mediated lung injury during P. aeruginosa infection. PMID- 29166667 TI - Flotillin scaffold activity contributes to type VII secretion system assembly in Staphylococcus aureus. AB - Scaffold proteins are ubiquitous chaperones that promote efficient interactions between partners of multi-enzymatic protein complexes; although they are well studied in eukaryotes, their role in prokaryotic systems is poorly understood. Bacterial membranes have functional membrane microdomains (FMM), a structure homologous to eukaryotic lipid rafts. Similar to their eukaryotic counterparts, bacterial FMM harbor a scaffold protein termed flotillin that is thought to promote interactions between proteins spatially confined to the FMM. Here we used biochemical approaches to define the scaffold activity of the flotillin homolog FloA of the human pathogen Staphylococcus aureus, using assembly of interacting protein partners of the type VII secretion system (T7SS) as a case study. Staphylococcus aureus cells that lacked FloA showed reduced T7SS function, and thus reduced secretion of T7SS-related effectors, probably due to the supporting scaffold activity of flotillin. We found that the presence of flotillin mediates intermolecular interactions of T7SS proteins. We tested several small molecules that interfere with flotillin scaffold activity, which perturbed T7SS activity in vitro and in vivo. Our results suggest that flotillin assists in the assembly of S. aureus membrane components that participate in infection and influences the infective potential of this pathogen. PMID- 29166669 TI - Frequency of five disease-causing genetic mutations in a large mixed-breed dog population (2011-2012). AB - BACKGROUND: A large and growing number of inherited genetic disease mutations are now known in the dog. Frequencies of these mutations are typically examined within the breed of discovery, possibly in related breeds, but nearly always in purebred dogs. No report to date has examined the frequencies of specific genetic disease mutations in a large population of mixed-breed dogs. Further, veterinarians and dog owners typically dismiss inherited/genetic diseases as possibilities for health problems in mixed-breed dogs, assuming hybrid vigor will guarantee that single-gene disease mutations are not a cause for concern. Therefore, the objective of this study was to screen a large mixed-breed canine population for the presence of mutant alleles associated with five autosomal recessive disorders: hyperuricosuria and hyperuricemia (HUU), cystinuria (CYST), factor VII deficiency (FVIID), myotonia congenita (MYC) and phosphofructokinase deficiency (PKFD). Genetic testing was performed in conjunction with breed determination via the commercially-available Wisdom PanelTM test. RESULTS: From a population of nearly 35,000 dogs, homozygous mutant dogs were identified for HUU (n = 57) and FVIID (n = 65). Homozygotes for HUU and FVIID were identified even among dogs with highly mixed breed ancestry. Carriers were identified for all disorders except MYC. HUU and FVIID were of high enough frequency to merit consideration in any mixed-breed dog, while CYST, MYC, and PKFD are vanishingly rare. CONCLUSIONS: The assumption that mixed-breed dogs do not suffer from single gene genetic disorders is shown here to be false. Within the diseases examined, HUU and FVIID should remain on any practitioner's rule-out list, when clinically appropriate, for all mixed-breed dogs, and judicious genetic testing should be performed for diagnosis or screening. Future testing of large mixed-breed dog populations that include additional known canine genetic mutations will refine our knowledge of which genetic diseases can strike mixed-breed dogs. PMID- 29166670 TI - Age-related differences in the respiratory microbiota of chickens. AB - In this era of next generation sequencing technologies it is now possible to characterise the chicken respiratory microbiota without the biases inherent to traditional culturing techniques. However, little research has been performed in this area. In this study we characterise and compare buccal, nasal and lung microbiota samples from chickens in three different age groups using 16S rRNA gene analysis. Buccal and nasal swabs were taken from birds aged 2 days (n = 5), 3 weeks (n = 5) and 30 months (n = 6). Bronchoalveolar lavage (BAL) samples were also collected alongside reagent only controls. DNA was extracted from these samples and the V2-V3 region of the 16S rRNA gene was amplified and sequenced. Quality control and OTU clustering were performed in mothur. Bacterial DNA was quantified using qPCR, amplifying the V3 region of the 16S rRNA gene. We found significant differences between the quantity and types of bacteria sampled at the three different respiratory sites. We also found significant differences in the composition, richness and diversity of the bacterial communities in buccal, nasal and BAL fluid samples between age groups. We identified several bacteria which had previously been isolated from the chicken respiratory tract in culture based studies, including lactobacilli and staphylococci. However, we also identified bacteria which have not previously been cultured from the respiratory tract of the healthy chicken. We conclude that our study can be used as a baseline that future chicken respiratory microbiota studies can build upon. PMID- 29166671 TI - The 15N-leucine single-injection method allows for determining endogenous losses and true digestibility of amino acids in cecectomized roosters. AB - This study was conducted to assess the influence of dietary protein content in poultry when using the 15N-leucine single-injection method to determine endogenous amino acid losses (EAALs) in poultry. Forty-eight cecectomized roosters (2.39 +/- 0.23 kg) were randomly allocated to eight dietary treatments containing protein levels of 0, 3%, 6%, 9%, 12%, 15%, 18% and 21%. Each bird was precisely fed an experimental diet of 25 g/kg of body weight. After feeding, all roosters were subcutaneously injected with a 15N-leucine solution at a dose of 20 mg/kg of body weight. Blood was sampled 23 h after the injection, and excreta samples were continuously collected during the course of the 48-h experiment. The ratio of 15N-enrichment of leucine in crude mucin to free leucine in plasma ranged from 0.664 to 0.763 and remained relatively consistent (P > 0.05) across all treatments. The amino acid (AA) profiles of total endogenous AAs, except isoleucine, alanine, aspartic acid, cysteine, proline and serine, were not influenced (P > 0.05) by dietary protein contents. The predominant endogenous AAs in the excreta were glutamic acid, aspartic acid, threonine, serine and proline. The order of the relative proportions of these predominant AAs also remained relatively constant (P > 0.05). The endogenous losses of total AAs determined with the 15N-leucine single-injection method increased curvilinearly with the dietary protein contents. The true digestibility of most AAs and total AAs was independent of their respective dietary protein levels. Collectively, the 15N leucine single-injection method is appropriate for determining EAALs and the true digestibility of AAs in poultry fed varying levels of protein-containing ingredients. PMID- 29166672 TI - Increased risk of dementia following herpes zoster ophthalmicus. AB - This retrospective cohort study aimed to examine the relationship between herpes zoster ophthalmicus (HZO) and the subsequent risk of dementia using a population based database. We retrieved the study sample from the Taiwan Longitudinal Health Insurance Database 2005. The study group included 846 patients with HZO, and the comparison group included 2538 patients without HZO. Each patient was individually followed for a 5-year period to identify those patients who subsequently received a diagnosis of dementia. We performed a Cox proportional hazards regression to calculate the hazard ratios (HRs) along with 95% confidence intervals (CIs) for dementia during the follow-up period between patients with HZO and comparison patients. The respective incidence rates of dementia per 1000 person-years were 10.15 (95% CI: 7.22~13.87) and 3.61 (95% CI: 2.61~4.89) for patients with HZO and comparison patients. The Cox proportional analysis showed that the crude HR of dementia during the 5-year follow-up period was 2.83 (95% CI: 1.83-4.37) for patients with HZO than comparison patients. After adjusting for patients' characteristics and comorbidities, HZO patients were still at a 2.97-fold greater risk than comparison patients for developing dementia. Furthermore, we found that of sampled male patients, the crude HR of dementia for patients with HZO was as high as 3.35 (95% CI = 1.79-6.28) compared to comparison patients. This study demonstrated an association between HZO and dementia. Clinicians must be alert to suspect dementia in patients with cognitive impairment who had prior HZO. PMID- 29166673 TI - Factors related to acupuncture response in patients with chronic severe functional constipation: Secondary analysis of a randomized controlled trial. AB - BACKGROUND: Acupuncture has been demonstrated to be effective and safe for chronic severe functional constipation (CSFC). However, which patients with CSFC will have a better response to acupuncture remains unclear. OBJECTIVE: To explore factors related to acupuncture response in patients with CSFC. METHODS: We performed a secondary analysis of a previous multicenter randomized controlled trial consisting of a 2-week run-in period, 8-week treatment, and 12-week follow up without treatment in which patients with CSFC were randomly allocated to an electroacupuncture group or a sham electroacupuncture group. Responders were defined as participants with an increase of at least one complete spontaneous bowel movement (CSBM) in week 20 compared with the baseline period. The CSBM responder rate in both groups was described, and the baseline characteristics of participants potentially related to acupuncture response were mainly analyzed using logistic regression analysis with bootstrapping techniques. RESULTS: A total of 1021 participants were analyzed in this study, of whom 516 (50.5%) were classified as responders. The CSBM responder rate in week 20 was significantly greater in the electroacupuncture group than in the sham electroacupuncture group (62.9% vs. 37.9%, respectively; P<0.001). Both age and comorbidity were negatively associated with clinical response: with every one-year increase in age, the likelihood of clinical response was reduced by 1.2% (OR 0.988, 95%CI 0.980 to 0.996; P = 0.005), and patients with comorbidities were approximately 42% less likely to respond to treatment (OR 0.581, 95%CI 0.248 to 0.914; P = 0.001). CONCLUSION: CSFC patients with increasing age and comorbidity may be less likely to respond to acupuncture. These findings contribute to guiding clinical practice in terms of pretreatment patient selection. Further research is needed to confirm the association. PMID- 29166675 TI - Perianal Dermatitis, Its Incidence, and Patterns of Topical Therapies in a Level IV Neonatal Intensive Care Unit. AB - OBJECTIVE: To define the incidence of perianal dermatitis (PD) and determine the usage pattern and cost efficacy of diaper products among neonates admitted to a level IV neonatal intensive care unit (NICU) including those with a diagnosis of neonatal abstinence syndrome (NAS). METHODS: A retrospective cohort study to evaluate neonates with PD based on number of orders for Aquaphor, Bagbalm, Desitin, Flanders, or Nystatin. Various demographic and clinical parameters were recorded. Usage patterns of these five products were analyzed, and their costs estimated. Subgroup analysis was performed among infants with NAS. RESULTS: Of 1,241 admissions, 56.2% had at least one diaper product ordered during their NICU stay, while 52.6% had multiple products ordered. Only 23.0% of all neonates had appropriate documentation of PD. The most common product ordered first was Aquaphor (64.3%), followed by Desitin (19.2%). Note that 86% term NAS infants had PD compared with 28% term non-NAS infants. The estimated product cost was $14,139 over 2 years, averaging $20 per patient. CONCLUSION: Over half of NICU neonates were exposed to one or more diaper products, usually without documented PD diagnosis. Term NAS infants had three times higher incidence of PD than term non NAS infants. The cost of diaper product use was significant, and possibly underestimated due to lack of documentation. PMID- 29166674 TI - Unpredictable chronic mild stress differentially impairs social and contextual discrimination learning in two inbred mouse strains. AB - Alterations in the social and cognitive domain are considered important indicators for increased disability in many stress-related disorders. Similar impairments have been observed in rodents chronically exposed to stress, mimicking potential endophenotypes of stress-related psychopathologies such as major depression disorder (MDD), anxiety, conduct disorder, and posttraumatic stress disorder (PTSD). Data from numerous studies suggest that deficient plasticity mechanisms in hippocampus (HC) and prefrontal cortex (PFC) might underlie these social and cognitive deficits. Specifically, stress-induced deficiencies in neural plasticity have been associated with a hypodopaminergic state and reduced neural plasticity persistence. Here we assessed the effects of unpredictable chronic mild stress (UCMS) on exploratory, social and cognitive behavior of females of two inbred mouse strains (C57BL/6J and DBA/2J) that differ in their dopaminergic profile. Exposure to chronic stress resulted in impaired circadian rhythmicity, sociability and social cognition in both inbred strains, but differentially affected activity patterns and contextual discrimination performance. These stress-induced behavioral impairments were accompanied by reduced expression levels of brain derived neurotrophic factor (BDNF) in the prefrontal cortex. The strain-specific cognitive impairment was coexistent with enhanced plasma corticosterone levels and reduced expression of genes related to dopamine signaling in hippocampus. These results underline the importance of assessing different strains with multiple test batteries to elucidate the neural and genetic basis of social and cognitive impairments related to chronic stress. PMID- 29166676 TI - Comparison of Melatonin Levels in the Colostrum between Vaginal Delivery and Cesarean Delivery. AB - OBJECTIVE: This study aims to compare melatonin levels in colostrum between vaginal and cesarean delivery. STUDY DESIGN: This cross-sectional study was conducted with 139 mothers who gave live births between February 2016 and December 2016. The mothers were divided into three groups according to the mode of delivery: 60 mothers (43.2%) in the vaginal delivery group, 47 mothers (33.8%) in the elective cesarean delivery, and 32 mothers (23.0%) in the emergency cesarean delivery group. Colostrum of the mothers was taken between 01:00 and 03:00 a.m. within 48 to 72 hours following the delivery, and the melatonin levels were measured using the enzyme-linked immunosorbent assay (ELISA) and compared between the groups. RESULTS: The melatonin levels in the colostrum were the highest in the vaginal delivery group, lower in the elective cesarean section group, and the lowest in the emergency cesarean group (265.7 +/- 74.3, 204.9 +/- 55.6, and 167.1 +/- 48.1, respectively; p < 0.001). The melatonin levels in the colostrum did not differ according to the demographic characteristics of the mothers, gestational age, birth weight, newborn sex, the Appearance, Pulse, Grimace, Activity, and Respiration (APGAR) scores, and for the requirement for neonatal intensive care. CONCLUSION: Our study results showed that melatonin levels in the colostrum of the mothers who delivered vaginally were higher than those who delivered by cesarean section. Considering the known benefits of melatonin for the newborns, we believe that vaginal delivery poses an advantage. PMID- 29166677 TI - Severe Trampoline Injuries: Incidence and Risk Factors in Children and Adolescents. AB - INTRODUCTION: Severe trampoline injuries in children and adolescents are rare; however, minor injuries are common and their incidence is increasing. Severe injuries are most commonly head and neck injuries. They may result in long-term morbidity. This study aimed to illustrate these severe injuries and to find out their incidence and risk factors. MATERIALS AND METHODS: This is a population based, prospective study in the Oulu region of Finland completed over 2 years (May 1, 2015 to April 31, 2017). All children (<16 years of age) with severe trampoline injuries were included. Cervical spine fractures, chest wall and skull fractures, lesions of internal organs, hip and knee dislocations, and permanent disorders of the peripheral veins or nerves were in prior defined as severe. Multiple jumpers, stunts, younger age, previous injuries, insufficient use of safety equipment, and lack of supervision were hypothesized as risk factors. RESULTS: There were 11 injured patients (10 boys). The annual incidence was 6.28/100,000 children <16 years of age. Mean age was 11.5 years. Severe injuries included five ligamentous cervical spine injuries and two sternal bone fractures. In addition, there were one lumbar spine ligament injury, two hip dislocations, and one severe axillary plexus nerve lesion. Eight out of 11 accidents were not seen by any adult and none of them happened under professional supervision. Most injuries (N = 8) happened by failed backflips. CONCLUSION: Most severe injuries happened in unsuccessful flips. Children should have an adult supervisor and flips should not be attempted.

PMID- 29166679 TI - Work-Related Musculoskeletal Disorders among Plastic Surgeons: A Systematic Review. AB - BACKGROUND: To date, no review has been conducted on the growing body of literature describing various work-related musculoskeletal disorders (MSDs), ergonomic hazards, and potential interventions relevant to plastic surgeons. This systematic review sought to (1) define the scope of coverage of this important issue in the peer-reviewed literature; (2) critically assess the evidence; and (3) provide recommendations for future directions. METHODS: We conducted a literature search of MEDLINE, Embase, Web of Science, and PubMed from the inception of each database until 2016. All articles reporting on work-related MSDs or ergonomics among plastic surgeons were reviewed, summarized, and assessed for trends. RESULTS: Sixteen articles met our inclusion criteria including five expert opinions, four cross-sectional studies and case reports/series, one review, and six experimental studies. Four articles presented evidence on disease burden. The most commonly described work-related MSD was cervical spine disease, for which one study reported a career prevalence of 24.7% (point prevalence in the general population: 0.1-0.4%); three studies reported 64 cases of surgeon work-related MSD resulting in surgical intervention, decreased productivity, or involuntary early retirement. Eight studies described interventions, most of which aimed to improve the ergonomics of microsurgery. CONCLUSION: This review found low-level evidence of plastic surgeons' vulnerability to a work-related MSD at times severe enough to end careers. Further investigation is needed to clearly define this important problem in plastic surgery. Specifically, future directions should include more methodologically rigorous epidemiologic studies evaluating disease burden. PMID- 29166680 TI - Knee Position during Surgical Wound Closure in Total Knee Arthroplasty: A Review. AB - Study areas concerning maximizing knee range of motion (ROM) following total knee arthroplasty (TKA) have come under focus by surgeons. Among the perioperative factors that were identified to affect ROM after TKAs is knee position during surgical wound closure. Therefore, the aim of this study was to review the impact of knee position during TKA wound closure on: (1) postoperative ROM, (2) wound related complications, (3) Knee Society Score (KSS), (4) postoperative pain, and (5) muscle strength and home functional recovery. A literature search was performed using PubMed, Ovid, and Google Scholar using various combinations of the following search terms: "wound closure," "knee position," "surgical closure," and "knee arthroplasty." The studies were evaluated for outcomes after TKA and stratified based on the knee position at surgical closure. After application of inclusion and exclusion criteria, seven studies were analyzed. The total number of patients included was 516 patients (259 patients in the flexion group and 257 patients in the full extension group). Based on the reviewed literature, wound closure in flexion was associated with significant improvement in ROM recovery at earlier follow-ups after TKA (four positive and three neutral studies), better early postoperative pain scores (two positive and one neutral study), and faster physical recovery (two positive studies) (better muscle strength and early achievement of physical therapy milestones) compared with wound closure in extension. No difference was found between wound closure in flexion compared with closure in extension in terms of long-term ROM recovery, long-term postoperative pain scores, wound-related complications (seven neutral studies), knee function measured by KSS (five neutral studies), or patient satisfactions after TKA. Although the current review is limited by the number of studies that are available in the literature, it demonstrates that overall, compared with extension, surgical wound closure in flexion may provide better ROM, faster recovery, comparable patient satisfaction, and no risk of higher wound complications. PMID- 29166681 TI - Difficult Cases in Robotic Arm-Assisted Total Knee Arthroplasty: A Case Series. AB - Sagittal deformity of the knee is commonly corrected to neutral biomechanical axis (+/-3 degrees) during total knee arthroplasty (TKA), which is a widely accepted goal. Recent advances in surgical technology have made it possible to accurately plan and fulfill these goals. One of these is robotic-assisted TKA, which has been noted to help increase accuracy and precision of restoring a neutral mechanical axis. While there are data confirming the ability of robotic devices to better correct knee alignment than the manual technique, there is a lack of data concerning the use of the robotic devices in more complex cases, such as those in patients with severe varus or valgus deformity, as well as in flexion contractures. Therefore, the purpose of this case study is to present three cases in which the robotic-assisted TKA device was used to correct a severe varus and severe valgus deformities. Based on this case series, it should be noted that the robotic device can also help correct severe varus/valgus deformities and flexion contractures. PMID- 29166682 TI - Bone Marrow Cellular Therapies: Novel Therapy for Knee Osteoarthritis. AB - Cellular therapies are emerging as potentially promising treatments for numerous musculoskeletal conditions, such as knee osteoarthritis (OA). As orthopaedic surgeons represent a sizable portion of the providers who deliver these therapies, it is particularly essential for them to understand their fundamental principles. One major principle is to identify the appropriate sources for obtaining these cells, with bone marrow being most common. Therefore, the purpose of this review was to provide an overview of cell-based therapies available for the treatment of knee OA with a focus on bone marrow-derived cellular therapies. Specifically, we discuss (1) bone marrow aspiration technique, (2) processing to bone marrow aspirate concentrate, and (3) the rational and clinical evidence for the use of bone marrow cellular therapies for the treatment of knee OA. PMID- 29166683 TI - The Learning Curve Associated with Robotic Total Knee Arthroplasty. AB - As with most new surgical technologies, there is an associated learning curve with robotic-assisted total knee arthroplasty (TKA) before surgeons can expect ease of use to be similar to that of manual cases. Therefore, the purpose of this study was to (1) assess robotic-assisted versus manual operative times of two joint reconstructive surgeons separately as well as (2) find an overall learning curve. A total of 240 robotic-assisted TKAs performed by two board-certified surgeons were analyzed. The cases were sequentially grouped into 20 cases and a learning curve was created based on mean operative times. For each surgeon, mean operative times for their first 20 and last 20 robotic-assisted cases were compared with 20 randomly selected manual cases performed by that surgeon as controls prior to the initiation of the robotic-assisted cases. Each of the surgeons first 20 robotic assisted, last 20 robotic assisted, and 20 controls were then combined to create 3 cohorts of 40 cases for analysis. Surgeon 1: First and last robotic cohort operative times were 81 and 70 minutes (p < 0.05). Mean operative times for the first 20 robotic-assisted cases and manual cases were 81 versus 68 minutes (p < 0.05). Mean operative times for the last 20 robotic assisted cases and manual cases were 70 versus 68 minutes (p > 0.05). Surgeon 2: First and last robotic cohort operative times were 117 and 98 minutes (p < 0.05). Mean operative times for the first 20 robotic-assisted cases and manual cases were 117 versus 95 (p < 0.05). Mean operative times for the last 20 robotic cohort cases and manual cases were 98 versus 95 (p > 0.05). A similar trend occurred when the times of two surgeons were combined. The data from this study effectively create a learning curve for the use of robotic-assisted TKA. As both surgeons completed their total cases numbers within similar time frames, these data imply that within a few months, a board-certified orthopaedic joint arthroplasty surgeon should be able to adequately perform robotic TKA without adding any operative times. PMID- 29166684 TI - [Implantation of a Modular Distal Femoral Replacement with Compressive Osseointegration as a Salvage Procedure in a Complex Femoral Posttraumatic Setting]. AB - BACKGROUND: Large bone defects and losses play a crucial role in both tumour surgery and in complex primary and revision total knee replacement. The established options of cemented or uncemented long intramedullary stems are limited by large bone defects and are at risk from relatively high exposure to aseptic loosening. There is no general valid agreement on implant fixation of the distal femur. A further option is the cementless fixation method with compressive osseointegration, based on the so-called Wolff law of bone remodelling. This method was developed in order to reduce the high loosening rates in revision arthroplasty due to intense stress shielding and is intended to be applied in patients with huge bone losses. The so-called Compress(r) system (or CPS) allows such a distal femur reconstruction. It has mainly been applied and evaluated in tumor endoprosthetics. There are currently few data on the application of this system in complex distal femoral posttraumatic deformity or revision arthroplasty. PATIENTS: A case report of two male patients aged 59/56 years with a 1-year follow-up is presented. Both patients had a complex post-traumatic femoral deformity with bone loss, prior surgery and an ipsilateral hip replacement. Implantation was performed of a modular total knee replacement, consisting of a cemented modular tibia base plate and distal femoral replacement with cementless implant fixation by compressive osseointegration. Both patients were clinically and radiologically evaluated prospectively. RESULTS: Good clinical and radiological results were demonstrated in both patients after distal femoral replacement by compressive osseointegration. There was no need for further or revision surgery. Both patients were rapidly able to resume their jobs. The survival rates for CPS were comparable to published values with conventional procedures. There are yet no long-term results or extensive data for revision arthroplasty or posttraumatic cases. CONCLUSIONS: Besides distal femoral replacement with compressive osseointegration in oncological arthroplasty, the indication of complex distal femoral settings with large bone defects can be evaluated for daily clinical routine. Especially if there is ipsilateral total hip replacement, this option might be used to avoid interprosthetic stress risers. PMID- 29166685 TI - [Evaluation of Inpatient Conservative Management of Acute, Subacute, and Chronic Back Pain]. AB - BACKGROUND: Backache is very common in the German population. It is a common reason for people to seek medical advice and specific back pain programs have been developed. The intention of this study is to evaluate the short and long term effects of conservative management of back pain in a German general hospital. Outcomes of interest were pain intensity, interference in daily functions, physical functioning and health related quality of life. PATIENTS AND METHODS: We examined 1010 patients with acute, subacute and chronic back pain, admitted to inpatient nonsurgical interventional therapy in a German hospital between July 2013 and July 2015. Outcomes were assessed at the end of the inpatient treatment and at 3, 6 and 12 months follow-up, using Numerical Rating Scales (NRS) for pain and daily function, the Hannover Ability Questionnaire for Measuring Back Pain-Related Functional Limitations (FFbH - R) and the German Version of the EuroQol Questionnaire (EQ-5D) for measuring health-related quality of life. The baseline questionnaire also included questions on the risk of developing long-term disability following back pain (HKF-R 10) for acute and subacute cases and the Mainz Pain Staging System (MPSS) for patients with chronic back pain. The return rate was 54% after 3 months, 38% after 6 months and 27% at 12 months follow-up. The results from the follow-up measurements (T2 - T5) were compared to the pre-treatment results (T1). Because of missing or insufficiently normal distributions nonparametric paired Wilcoxon tests were used to test differences over time for each variable. Level of significance was adjusted for multiple testing. In addition, effect sizes were computed to estimate the clinical relevance of statistically significant results. RESULTS: Pain intensity and impact of pain on daily function were significantly lower at the end of the inpatient treatment (T2). The results remained largely stable at the 3, 6 and 12 month follow-ups. Significant improvements were found in physical functioning and health-related quality of life. These improvements were maintained equally at the 3, 6 and 12 month follow-ups. In consequence, working ability increased during the follow-up period. Calculated effect sizes showed large effects for pain intensity, interference and quality of life (r = 0.51 to 0.85) and predominately moderate effects (r = 0.45 to 0.62) for physical functioning at all measurement points. The percentage of patients who had an operation due to continuing back pain after conservative treatment was 7.8, 9.9, and 12.3 at the 3, 6, and 12 month follow-ups, respectively. CONCLUSION: Persistent effects of inpatient conservative treatment of back pain were found for all outcome variables. The specific approach appears to be effective in conservative treatment programs of back pain. In the end, it's not about the alternative of surgery or conservative treatment for back pain. Treatment has to be coordinated with the patient in terms of participative decisions.

AB - AIM: CoCrMo alloys are contraindicated for sufferers from allergy. For these patients, uncemented and cemented prostheses made of non-allergenic titanium alloy are indicated. Knee prostheses machined from that alloy, however, may have poor tribological behaviour, especially in contact to UHMWPE inlays. Therefore, high-strength oxide ceramics may be especially suitable for knee replacement in allergy patients with mobile bearing prostheses. For adhesion to bone cement, the ceramic surface only exhibits mechanical retention spots that are less adequate than those with a textured metal surface. Generating undercuts by corundum blasting is highly efficient for mechanical adhesion to a CoCrMo surface, but is not possible on a ceramic surface, due to the brittleness of ceramics. Lack of retention of bone cement promotes micromotions of the prostheses. As a consequence of micromotions, early aseptic loosening is predictable. Silicoating (silicate and silane layering) of the ceramic surface would allow specific adhesion and hence would result in increased and hydrolytically more stable bonding between the bone cement and the prosthesis surface - thereby preventing early aseptic loosening. Silicoating, however, presupposes a chemically active surface that is not blocked by a layer of chemisorbed molecules, e.g. water. Desorption of this chemisorbed layer is mandatory and can be attained by baking out the surface. METHOD: In order to evaluate the effectiveness of surface activation via thermal treatment by baking out, with subsequent silicoating of the surface, the bond strengths of thermally treated and silicate layered ZPTA samples were compared with thermally treated surfaces that had not been silicoated. In our study of thermal surface treatment for baking out the surface, we focused on the question of whether there is a minimal "critical" temperature Ts for effective desorption of a chemisorbed water layer. The samples were prepared for the traction-adhesive strength test (sequence: ceramic disc, silicate and silane layering, protective lacquer ("PolyMA" layer), bone cement, TiAlV probes for the traction-adhesive strength test) and their traction-adhesive strengths were then measured. RESULTS: The bond strength was measured as a function of temperature for ceramic discs that had been baked out and subsequently silicoated. This was graduated, exhibits with a pronounced increase in the bond strength at a baking temperature of Ts ~ 350 degrees C. The observed bond strengths before the step are <= 20 MPa and after the step >= 30 MPa. CONCLUSION: Silicoating is effective in achieving high bond strength of bone cement on surfaces of oxide ceramics and can also stabilise the long term behaviour of the bond strength, provided the surface has been thermally treated prior to silicoating. Because of the proposed migration of the silicoating layer, micromotions and debonding should be widely reduced or even eliminated.

AB - BACKGROUND: In Germany there are more than 70 million bicycles. Because of technical progress, over 200,000 electro-assisted bikes were sold in Germany in 2010 alone. In 2013, the number increased to 410,000. Currently more than 1.6 million electric bicycles are used here. One of the largest user groups are seniors. Accident researchers fear an increased risk of accidents/injuries. METHODS: For one year, all cycling accidents involving electric bicycles and senior citizens were collected and analysed in 23 hospitals of the TraumaNetwork NorthWest and by the local police authorities. RESULTS: A comparison of the senior and younger electro-assisted cyclists showed a higher risk of injury for seniors in the initial analysis. A further comparative analysis of severely injured seniors who were riding an electro-assisted bike with those who used a conventional bicycle contradicted this. There was no statistical significance. The risk of an accident increased with age, but not with bicycle type. CONCLUSION: To reduce accidents, driving training and medical precautionary examinations could be used to detect losses of performance, cognitive processing and balance. In the future, they should become an integral part of the health care system and the services of practicing physicians. PMID- 29166688 TI - [Perioperative Management in Total Knee Arthroplasty]. AB - The themes of this paper are the clinical relevance and technique of perioperative management in total knee arthroplasty. Due to the number of unsatisfied patients after knee arthroplasty, optimisation of processes seems to be necessary. Beside patient preparation and rehabilitation, the surgical technique and implant choice in perioperative management are important. This means the use of tourniquet and drains, the application of tranexamic acid and pain management. These items are presented and discussed in detail in this paper.

AB - Multiple sclerosis (MS), a chronic progressive inflammatory disease of the central nervous system, causes frequent disability, mood disorders, fatigue, and cognitive dysfunction. As a part of the last, social cognition is frequently disturbed in MS patients. It comprises empathy and social perception of emotions from facial, bodily and vocal cues. Social cognitive deficits worsen affect decoding, interpersonal relationship, and quality of life. Despite the impact of these deficits on global functioning, only a small number of studies have investigated its correlations and overlaps with MS symptoms. This review focuses on the definition and anatomy of social cognition and draws attention to findings of neuropsychological and neuroimaging studies on social cognitive performance in MS.Results of the available studies show that social cognitive deficits are already measurable in early stages of MS. Over time course of the disease, neuropsychological and neuroimaging studies show an increase of disease burden and social and non-social cognitive impairment following the hypothesis of a disconnection syndrome resulting from gray and white matters lesions. These structural changes might exceed a threshold of compensatory restorative and neuroplasticity mechanisms and finally lead to deficits in social cognition. Considering this burden in social functioning, a further assessment of sociocognitive deficits in MS is urgently needed to provide specific therapeutic approaches and to improve quality of life.

This study discusses whether it was his period in the Russian Empire in the years 1886 to 1891 when he worked at Dorpat University (today Tartu, Estonia) that raised his popularity in Russia. Our research shows that all of his writings which had been translated into Russian language derive from a period much later than Dorpat. Moreover, none of his students has ever reached a scientific position which would have enabled him to become a proponent of Kraepelin's ideas in Russia. Despite his stay at Dorpat was important for Kraepelin's scientific development, it had no major impact on Russian psychiatry.The later perception of Kraepelin in Russia and in the Soviet Union is quite inconsistent. At some point of time, his works on experimental psychology were appreciated, which was probably connected with the rise of reflexology in Russian and, especially, Soviet psychiatry. On the other hand, it was Kraepelin's merits in the classification of psychiatric diseases that have mainly been acknowledged. PMID- 29166693 TI - [The biased expert: An unknown quantity]. AB - Academic publications have so far hardly paid any attention to the topic of biased medical experts or expert opinions. This is the first attempt to systematically describe and analyze the issue, drawing on the author's many years of giving expert opinions as a neuropsychiatrist on matters relating to social legislation and civil law. In addition to dealing with questions of definition, this article outlines the features of biased expert opinions, particularly focusing on the role of insurance and private experts. Finally, proposals are made to initiate a discussion on how to prevent biased expert opinions and improve their registration.

AB - The aim of this study was to compare the satisfaction and success of treatment for pain patients who were interdisciplinary (anaesthesiological, psychosomatic, neurological, orthopedic) treated or underwent neurological care alone. Methods We selected 183 patients who were treated in our neurological clinic and in our interdisciplinary pain management center (IST). Of these, 142 patients having polyneuropathy, headache or muskuloskelettal pain were included in the final analysis. 39 patients (27.5 %) were treated in the IST and 103 patients were treated exclusively by a neurologist. These patients were asked to complete a questionnaire, and were queried about the satisfaction and pain parameters. Results The neurological and multidisciplinary pain treatment led to a similar improvement in pain (p < 0.001). This effect was independent of the underlying disease. The interdisciplinary outpatient treatment resulted not primarily in an increased patient satisfaction. Conclusions The reduction of pain and patient satisfaction of neurological outpatient pain treatment were comparable with those of a multidisciplinary outpatient therapy. The only significant advantage of the interdisciplinary treatment was lower hospitalization rate after therapy. This result cannot evaluate the efficiency of inpatient or day hospital pain management, but suggests that in many cases a neurological outpatient pain therapy is sufficient, so that neurological outpatient care should be promoted.

AB - Summary Umbilical hernia occur in both adults and children. For over 100 years, umbilical hernia in children has been treated surgically by the Spitzy method. With adult patients, meshes are being increasingly used. The purpose of our study was to analyse Spitzy herniotomy with respect to the recurrence rate in children and adults. Material and Methods Over a period of 7 years, 383 children (age < 16 years) with umbilical hernia were treated surgically; after applying the exclusion criteria, 370 patients were evaluated. At the same time, 106 adult patients (age > 16 years) were operated for an umbilical hernia: 31 patients were treated with direct suture and thus are included in our study as comparison group. Results The young patients had an average age of 33.81 months and were 44% female and 56% male. After direct Spitzy suture, a low recurrence rate of 1.1% (n = 4) in infancy could be achieved. The average age of the adult patients was 54.55 years; 32% were female, 68% male. In comparison to the group of children, the recurrence rate in adult surgery was 12.9% (n = 4) after direct suture. Conclusion As confirmed in our study, umbilical herniotomy by direct suture in childhood has been the method of choice and gold standard for more than 100 years. Mesh implantation is still not necessary in childhood. PMID- 29166696 TI - [Fluorescence Cholangiography in Comparison to Radiographic Cholangiography During Laparoscopic Cholecystectomy]. AB - BACKGROUND: The reported incidence rate of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is 0.3%. However, routine use of intraoperative cholangiography (IOC) is a controversial, due to the additional cost and radiation exposure. The aim of this study was to assess the application of fluorescence cholangiography (FC) in comparison to IOC and to LC without any intraoperative imaging. MATERIALS AND METHODS: This prospective study included 230 patients undergoing LC in our institution. The subjects were divided into two groups. In the first group, with 170 patients, both FC and IOC were performed following a standardised protocol. In second group, with 60 patients, FC was compared to LC without any intraoperative imaging. The data were then analysed with respect to procedure time and identification of predefined anatomical structures. RESULTS: The mean age and body mass index in the first group were 54.4 +/- 15.7 years and 27.9 +/- 5.7 kg/m2, respectively. The mean operative time was 67.6 +/- 23.3 min. FC was performed more rapidly than IOC (1.5 +/- 0.9 vs.7.3 +/- 5.0 min) and visualised the cystic duct (DC) in 67.5% of patients and the common bile duct (DHC) in 66.2% of patients before dissection of Calot's triangle. During dissection, DC and DHC were detected in 95.9% and 71.2% of patients, respectively. BMI > 25 kg/m2 and male gender significantly reduced the identification rate of DC before dissection of Calot's triangle. Bile leakage from the liver bed after cholecystectomy was found in 3 cases (1.8%) by FC. In 2 patients (1.2%), IOC visualised the DC joining directly to the right hepatic duct. In 1 of these 2 cases (0.6%), the anatomical variation was identified first by FC. Intraductal filling defects were detected in 9 patients (5.3%) using IOC, compared to 1 patient (0.6%) using FC. In the second group, the visualisation rates of DC and DHC were 80.0 and 53.3%, respectively, with FC and 60.0 and 43.3%, respectively, during LC without any imaging. Surgeons confirmed an increase in safety in 70.0% of patients using FC. CONCLUSION: FC is a simple procedure for non-invasive real-time visualisation of bile duct anatomy during LC. Earlier identification of biliary anomalies and bile leakage increases the operative safety and enables immediate care. In obese patients, FC has limited validity.

AB - BACKGROUND: There are numerous published studies on patient-related risk factors for the development of anastomotic failure. We therefore investigated the influence of patient-unrelated risk factors for the development and course of treatment of anastomotic failure in colorectal surgery. PATIENT SAMPLE: From May 1, 2015, until December, 31, 2016, n = 179 post-colorectal surgery patients were analysed. Overall, n = 14 patients suffered from anastomotic failure. These patients' course of treatment was analysed in a Morbidity and Mortality Conference (M+M conference) structured according to the London Protocol. RESULTS: Irregularities in process quality were the most frequent analysis result (n = 8/14), followed by irregularities in post-treatment (n = 6/14). Irregularities in surgical technique (n = 2/14) and surgery procedure (n = 3/14) were less frequent. Future treatment approaches were identified for most patients (n = 11/14). On the basis of the analysis of data from four of these eleven patients, the strategy for future treatment was modified. CONCLUSION: Therapist- and environment-specific irregularities can be systematically identified in M+M conferences structured according to the London Protocol. This analysis is the prerequisite for quality improvement and must systematically complement the analysis of patient-related risk factors. PMID- 29166698 TI - [The Value of Endoscopic Decompression in Surgical Therapy of Carpal Tunnel Syndrome]. AB - Carpal tunnel syndrome is one of the most common diseases in hand surgery. The gold standard in therapy is the surgical release of the carpal tunnel. We provide a brief update on the relevant pathogenesis, diagnosis and therapy and discuss questions related to minimal invasive decompression of the median nerve. Together with a review of the current literature, we report on our experiences in minimally invasive carpal tunnel release via a monoportal endoscopic access in over 700 cases. In conclusion, the endoscopic technique provides superior convalescence and patient safety is comparable to open methods. In addition, advantages and disadvantages of the various techniques are discussed. PMID- 29166699 TI - Comparison of clinical outcomes of coronary artery stent implantation in patients with end-stage chronic kidney disease including hemodialysis for three everolimus eluting (EES) stent designs: Bioresorbable polymer-EES, platinum chromium-EES, and cobalt chrome-EES. AB - BACKGROUNDS: New-generation bioresorbable polymer-everolimus eluting stents (BP EES) are available. This study aimed to compare the clinical outcomes for BP-EES compared to more established stent designs, namely the platinum chromium-EES (PtCr-EES) and cobalt chrome-EES(CoCr-EES) in patients with the end-stage chronic kidney disease (CKD) including hemodialysis (HD). METHODS: One-hundred-forty-one consecutive stents (BP-EES [n = 44], PtCr-EES [n = 45], and CoCr-EES [n = 52]) were implanted in 104 patients with CKD. All patients underwent a follow-up coronary angiography at 12 months after implantation. End-stage CKD was defined as an estimated glomerular filtration rate (eGFR) <30 mL/min/1.73 m2 , or the need for HD. The following outcome variables were compared among the three stent groups after implantation and the 12-month follow-up: target lesion revascularization (TLR), stent thrombosis (ST), and major adverse cardiac event (MACE). Minimal stent diameter (MSD) and %diameter-stenosis (%DS) were measured using quantitative coronary angiography. RESULTS: The overall rate of TLR and MACE was 14.6% and 30.8%, respectively, with no incidence of ST. Immediately after implantation, the MSD (P = 0.22) and %DS (P = 0.42) were equivalent among the three groups. However, at the 12-month follow-up, a tendency towards higher TLR was observed for the BP-EES group (22.7%) compared with the PtCr-EES (8.8%) and CoCr-EES (9.6%) groups (P = 0.07). Late loss in lumen diameter was also significantly greater for the BP-EES (0.51 +/- 0.64 mm) group than either the PtCr-EES (0.20 +/- 0.61 mm) and CoCr-EES (0.25 +/- 0.70 mm) groups (P = 0.03). CONCLUSIONS: BP-EES might increase the risk of in-stent restenosis in patients with end-stage of CKD or the need for HD. PMID- 29166700 TI - DLP1-dependent mitochondrial fragmentation and redistribution mediate prion associated mitochondrial dysfunction and neuronal death. AB - Mitochondrial malfunction is a universal and critical step in the pathogenesis of many neurodegenerative diseases including prion diseases. Dynamin-like protein 1 (DLP1) is one of the key regulators of mitochondrial fission. In this study, we investigated the role of DLP1 in mitochondrial fragmentation and dysfunction in neurons using in vitro and in vivo prion disease models. Mitochondria became fragmented and redistributed from axons to soma, correlated with increased mitochondrial DLP1 expression in murine primary neurons (N2a cells) treated with the prion peptide PrP106-126 in vitro as well as in prion strain-infected hamster brain in vivo. Suppression of DLP1 expression by DPL1 RNAi inhibited prion induced mitochondrial fragmentation and dysfunction (measured by ADP/ATP ratio, mitochondrial membrane potential, and mitochondrial integrity). We also demonstrated that DLP1 RNAi is neuroprotective against prion peptide in N2a cells as shown by improved cell viability and decreased apoptosis markers, caspase 3 induced by PrP106-126 . On the contrary, overexpression of DLP1 exacerbated mitochondrial dysfunction and cell death. Moreover, inhibition of DLP1 expression ameliorated PrP106-126 -induced neurite loss and synaptic abnormalities (i.e., loss of dendritic spine and PSD-95, a postsynaptic scaffolding protein as a marker of synaptic plasticity) in primary neurons, suggesting that altered DLP1 expression and mitochondrial fragmentation are upstream events that mediate PrP106-126 -induced neuron loss and degeneration. Our findings suggest that DLP1 dependent mitochondrial fragmentation and redistribution plays a pivotal role in PrPSc -associated mitochondria dysfunction and neuron apoptosis. Inhibition of DLP1 may be a novel and effective strategy in the prevention and treatment of prion diseases. PMID- 29166701 TI - When is protection from impact needed for the face as well as the eyes in occupational environments? AB - BACKGROUND: The most commonly identified reason for requiring or using occupational eye and face protection is for protection against flying objects. Standards vary on what risk may require protection of the eyes alone and what requires protection for the whole face. Information on the minimum energy transfer for face damage to occur is not well-established. METHODS: The heads of pigs were used as the common model for human skin. A 6 mm steel ball projected at velocities between 45 and 135 m/s was directed at the face area. Examples of impacts were filmed with a high-speed camera and the resulting damage was rated visually on a scale from 1 (no visible damage) to 5 (penetrated the skin and embedded in the flesh). RESULTS: The results for the cheek area indicate that 85 m/s is the velocity above which damage is more likely to occur unless the skin near the lip is included. For damage to the lip area to be avoided, the velocity needs to be 60 m/s or less. CONCLUSION: The present data support a maximum impact velocity of 85 m/s, provided the thinner and more vulnerable skin of the lids and orbital adnexa is protected. If the coverage area does not extend to the orbital adnexa, then the absolute upper limit for the velocity is 60 m/s. At this stage, eye-only protection, as represented by the lowest level of impact test in the standards in the form of a drop ball test, is not in question. PMID- 29166702 TI - Impact of active cancer disease on the outcome of patients undergoing transcatheter aortic valve replacement. AB - BACKGROUND: Patients undergoing transcatheter aortic valve replacement (TAVR) are often characterized by risk factors not reflected in conventional risk scores. In this context, little is known about the outcome of patients suffering from an active cancer disease (ACD). The objective was to determine the prevalence, clinical characteristics, perioperative outcomes, and mortality of patients with ACD undergoing TAVR compared to those with a history of cancer (HCD) and controls without known tumor disease. METHODS: TAVR patients between 02/2006 and 09/2014 were stratified according to the presence of ACD, HCD, and control. All-cause mortality at 1-year was the primary end point. All end point definitions were subject to the Valve Academic Research Consortium II definitions. RESULTS: Overall, 1821 patients were included: 99 patients (5.4%) suffered from ACD and 251 patients (13.8%) had HCD. ACD was related to a solid organ or hematological source in 72.7% and 27.3%, respectively. Patients with ACD were more often male (P = 0.004) and had a lower logisticEuroScore I (P = 0.033). Overall rates of VARC-II defined periprocedural myocardial infarction, stroke, bleeding, access site complications, and acute kidney injury were not different between groups. Thirty-day mortality did not differ between patients with ACD, HCD, and controls (6.1% vs 4.4% vs 7.6%, P = 0.176). All-cause 1-year mortality was higher in patients with ACD compared HCD and controls (37.4% vs 16.4% vs 20.8%, P < 0.001). ACD was an independent predictor of all-cause 1-year mortality (HR 2.10, 95%-CI 1.41-3.13, P < 0.001). CONCLUSION: The presence of ACD in patients undergoing TAVR is associated with significantly higher 1-year mortality. PMID- 29166703 TI - In-hospital outcomes in invasively managed acute myocardial infarction patients who receive morphine. AB - OBJECTIVE: We aimed to analyze the association between morphine and in-hospital outcomes in invasively managed ST elevation myocardial infarction (STEMI) and non ST elevation acute coronary syndrome (NSTE-ACS) patients. BACKGROUND: Morphine is commonly used for analgesia in the setting of acute coronary syndromes (ACS); however, recently its utility in ACS has come under closer scrutiny. METHODS: We identified all STEMI and NSTE-ACS patients undergoing coronary angiogram +/- percutaneous intervention between January 2009 and July 2016 in our center and recorded patient characteristics and inpatient outcomes. RESULTS: Overall, 3027 patients were examined. Overall, STEMI patients who received morphine had no difference in in-hospital mortality [4.18% vs. 7.54%, odds ratio (OR): 0.36, P = 0.19], infarct size (mean troponin level 0.75 ng/mL vs. 1.29 ng/mL, P = 0.32) or length of hospital stay (P = 0.61). The NSTE-ACS patients who received morphine had a longer hospital stay (mean 6.58 days vs. 4.78 days, P < 0.0001) and larger infarct size (mean troponin 1.16 ng/mL vs. 0.90 ng/mL, P = 0.02). Comparing matched patients, the use of morphine was associated with larger infarct size (mean troponin 1.14 +/- 1.92 ng/mL vs. 0.83 +/- 1.49 ng/mL, P = 0.01), longer hospital stay (6.5 +/- 6.82 days vs. 4.89 +/- 5.36 days, P = 0.004) and a trend towards increased mortality (5% vs. 2%, OR: 2.55, P = 0.06) in NSTE-ACS patients but morphine did not affect outcomes in the propensity matched STEMI patients. CONCLUSION: In a large retrospective study, morphine was associated with larger infarct size, a longer hospital stay and a trend towards increased mortality in invasively managed NSTE-ACS patients even after adjustment for clinical characteristics. PMID- 29166704 TI - The prevalence and causes of visual impairment in seven-year-old children. AB - BACKGROUND: To report the prevalence and causes of visual impairment in seven year-old children in Iran and its relationship with socio-economic conditions. METHODS: In a cross-sectional population-based study, first-grade students in the primary schools of eight cities in the country were randomly selected from different geographic locations using multistage cluster sampling. The examinations included visual acuity measurement, ocular motility evaluation, and cycloplegic and non-cycloplegic refraction. Using the definitions of the World Health Organization (presenting visual acuity less than or equal to 6/18 in the better eye) to estimate the prevalence of vision impairment, the present study reported presenting visual impairment in seven-year-old children. RESULTS: Of 4,614 selected students, 4,106 students participated in the study (response rate 89 per cent), of whom 2,127 (51.8 per cent) were male. The prevalence of visual impairment according to a visual acuity of 6/18 was 0.341 per cent (95 per cent confidence interval 0.187-0.571); 1.34 per cent (95 per cent confidence interval 1.011-1.74) of children had visual impairment according to a visual acuity of 6/18 in at least one eye. Sixty-six (1.6 per cent) and 23 (0.24 per cent) children had visual impairment according to a visual acuity of 6/12 in the worse and better eye, respectively. The most common causes of visual impairment were refractive errors (81.8 per cent) and amblyopia (14.5 per cent). Among different types of refractive errors, astigmatism was the main refractive error leading to visual impairment. According to the concentration index, the distribution of visual impairment in children from low-income families was higher. CONCLUSION: This study revealed a high prevalence of visual impairment in a representative sample of seven-year-old Iranian children. Astigmatism and amblyopia were the most common causes of visual impairment. The distribution of visual impairment was higher in children from low-income families. Cost-effective strategies are needed to address these easily treatable causes of visual impairment.

AB - Monoamines, acting as hormones and neurotransmitters, play a critical role in multiple physiological processes ranging from cognitive function and mood to sympathetic nervous system activity, fight-or-flight response and glucose homeostasis. In addition to brain and blood, monoamines are abundant in several tissues, and dysfunction in their synthesis or signaling is associated with various pathological conditions. It was our goal to develop a method to detect these compounds in peripheral murine tissues. In this study, we employed a high performance liquid chromatography method using electrochemical detection that allows not only detection of catecholamines but also a detailed analysis of nine monoamines and metabolites in murine tissues. Simple tissue extraction procedures were optimized for muscle (gastrocnemius, extensor digitorum longus and soleus), liver, pancreas and white adipose tissue in the range of weight 10-200 mg. The system allowed a limit of detection between 0.625 and 2.5 pg MUL-1 for monoamine analytes and their metabolites, including dopamine, 3,4-dihydroxyphenylacetic acid, 3-methoxytyramine, homovanillic acid, norepinephrine, epinephrine, 3 methoxy-4-hydroxyphenylglycol, serotonin and 5-hydroxyindoleacetic acid. Typical concentrations for different monoamines and their metabolization products in these tissues are presented for C57Bl/6 J mice fed a high-fat diet.

AB - Objective: To establish 3-{4-[2-hydroxyl-(1-methylethylamino) propoxy] phenyl} propionic acid cetylesters (PAC) modified nanoparticles, and preliminarily explore its cardiomyocyte-targeting function and protection effects on myocardium. Methods: (1) HL-1 myocardial cells were divided into cyanidin-3 (Cy3) marked non-targeted small interference RNA (Cy3-siNC) group and Cy3 marked small interference RNA designed for the nuclear factor kappa B (NF-kappaB)-p65 gene (Cy3-si435) group according to the random number table, with 3 wells in each group. Cells in Cy3-siNC group were transfected with Cy3-siNC, while cells in Cy3 si435 group were transfected with Cy3-si435. At transfection hour 24, the mRNA expression of NF-kappaB-p65 of cells was determined by real-time fluorescent quantitative polymerase chain reaction. (2) Multiple emulsificating solvent evaporating method was adopted to prepare PAC modified nanoparticles carried with Cy3-siNC (Cy3-siNC-PAC) and PAC modified nanoparticles carried with Cy3-si435 (Cy3-si435-PAC). The morphology of Cy3-si435-PAC nanoparticles was observed with scanning electron microscope, and the size and potential of Cy3-si435-PAC nanoparticles were detected by nanometer particle size and zeta potential analyzer. The entrapment efficiency and drug loadings of Cy3-si435-PAC nanoparticle were determined with ultraviolet spectrophotometer. The release of Cy3-si435 of Cy3-si435-PAC nanoparticles was determined by dialysis method. (3) Another batch of HL-1 cells were divided into 4 groups according to the random number table, with 9 wells in each group. Cells in negative control group were added with 5 MUL phosphate buffer. Cells in 25, 50, and 100 mg/mL Cy3-si435-PAC nanoparticles groups were added with 5 MUL 25, 50, and 100 mg/mL Cy3-si435-PAC nanoparticles, respectively. At transfection hour 6, 12, and 24, proliferation activity of cells in 3 wells of each group was detected by methyl thiazolyl tetrazolium method, respectively. (4) Another batch of HL-1 cells were cultured for 24 h, and then treated with 100 MUL Cy3-si435-PAC nanoparticles. At transfection hour 0, 4, 8, 12, and 24, the percentage of cells uptaking Cy3-si435 PAC nanoparticles in 3 wells were detected by flow cytometry, respectively. (5) Another batch of HL-1 cells were divided into 2 groups according to the random number table, with 3 wells in each group. Cells in Cy3-siNC-PAC group were added with 100 MUL Cy3-siNC-PAC nanoparticles, while cells in Cy3-si435-PAC group were added with 100 MUL Cy3-si435-PAC nanoparticles. At transfection hour 24, the mRNA expression of NF-kappaB-p65 of cells was determined by real-time fluorescent quantitative polymerase chain reaction. (6) Six male C57BL/6J mice were divided into 2 groups according to the random number table, with 3 mice in each group. Mice in Cy3-siNC-lipopolysaccharide (LPS) group and Cy3-si435-LPS group were respectively injected with 500 MUL Cy3-siNC-PAC nanoparticles and Cy3-si435-PAC nanoparticles (50 mg/mL) in the tail vein. At injection hour 24, mice in the two groups were intraperitoneally injected with 10 mg/kg LPS to induce myocardial injury. At post injury hour 24, the distribution of nanoparticles in mice was detected with small animal imager. (7) Another 9 male C57BL/6J mice were divided into 3 groups according to the random number table, with 3 mice in each group. Mice in Cy3-siNC-normal saline (NS) group and Cy3-siNC-LPS group were injected with 500 MUL 50 mg/mL Cy3-siNC-PAC nanoparticles in the tail vein, while mice in Cy3-si435-LPS group were injected with 500 MUL 50 mg/mL Cy3-si435-PAC nanoparticles. At injection hour 24, mice in Cy3-siNC-NS group were intraperitoneally injected with NS, while mice in Cy3-siNC-LPS group and Cy3 si435-LPS group were injected with 10 mg/kg LPS to induce myocardial injury. At post injury hour 24, pathological changes of myocardium of mice in each group were observed with HE staining. Data were processed with t test and one-way analysis of variance. Results: (1) The mRNA expression of NF-kappaB-p65 of cells in Cy3-si435 group was 0.183+/-0.004, significantly lower than 1.003+/-0.092 in Cy3-siNC group (t=15.46, P<0.01). (2) The form of prepared Cy3-si435-PAC nanoparticles was good, with particle size of 146.0 nm, potential of -29.2 mV, entrapment efficiency of (86.9+/-1.1) %, drug loadings of (25.4+/-0.9) %, and stable Cy3-si435 release. (3) At transfection hour 6, 12, and 24, there were no statistically significant differences in proliferation activity of cells in the 4 groups (with F values from 0.129 to 2.512, P values above 0.05). (4) At transfection hour 0, 4, 8, 12, and 24, the percentages of cells uptaking Cy3 si435-PAC nanoparticles were (0.79+/-0.06)%, (31.04+/-1.59)%, (51.64+/-2.67)%, (68.15+/-2.60)%, and (83.68+/-4.67)%, respectively. (5) The mRNA expression of NF kappaB-p65 of cells in Cy3-si435-PAC group was 0.286+/-0.015, significantly lower than 1.002+/-0.073 in Cy3-siNC-PAC group (t=16.62, P<0.01). (6) At post injury hour 24, uniform distribution of nanoparticles could be observed in cardiomyocytes of mice in Cy3-siNC-LPS group and Cy3-si435-LPS group. (7) The structure of myocardial fibers of mice in Cy3-siNC-NS group was dense, with no inflammatory cells infiltration and uniform distribution of cytoplasm. The structure of myocardial fibers of mice in Cy3-siNC-LPS group were loose, with inflammatory cells infiltration and scattered distribution of cytoplasm. The structure of myocardial fibers of mice in Cy3-si435-LPS group was denser, with no obvious inflammatory cells infiltration and uniform distribution of cytoplasm. Conclusions: Cy3-si435-PAC nanoparticles have good morphology, uniform particle size, normal potential distribution, and no cell cytotoxicity. Cy3-si435-PAC nanoparticles can be effectively uptaked by HL-1 cells and suppress NF-kappaB-p65 mRNA expression. They also can effectively target to mice cardiomyocytes to reduce inflammatory cells infiltration and alleviate the myocardial injury of mice induced by LPS.

AB - Objective: To investigate the effects of astragalus polysaccharide (AP) on cardiac dysfunction in rabbits with severe scald injury. Methods: Sixty-four New Zealand white rabbits were divided into pure scald group and AP group according to the random number table, with 32 rabbits in each group. Rabbits in the two groups were all inflicted with 30% total body surface area full-thickness scald on the back. Immediately after injury, rabbits in two groups were intraperitoneally injected with lactated Ringer's solution once for antishock. Rabbits in AP group were intraperitoneally injected with 10 mL AP solution with the dosage of 200 mg/kg 10 min after injury and the following 6 days respectively, once a day. Rabbits in pure scald group were injected with 10 mL normal saline instead. Eight rabbits of each group were respectively selected before injury hour (BIH) 1 and on post injury day(PID) 1, 3, 7, and 14 to collect blood samples from ear marginal vein, and then sacrificed immediately to collect hearts at each time point post injury. The morphology of myocardium was observed after HE staining. The serum content of cardiac troponin I (cTnI) was detected by enzyme-linked immunosorbent assay (ELISA). The serum content of aspartate transaminase (AST), creatine kinase (CK), CK isoenzyme-MB (CK-MB), lactate dehydrogenase (LDH) was detected by fully automatic chemistry analyzer. The content of angiotensin II (Ang II) in serum and myocardium was detected with radioimmunoassay and the content of endothelin 1 (ET-1) in serum and myocardium was detected by ELISA. Another 8 normal rabbits were sacrificed to detect the content of Ang II and ET-1 in the myocardium as the value of the two groups of scalded rabbits at BIH 1. The serum content of superoxide dismutase (SOD) and malondialdehyde (MDA) was detected by ELISA. The values of whole blood viscosity (etab), reductive viscosity of whole blood (etar), plasma viscosity (etap), hematocrit (HCT), erythrocyte rigidity index (TK), erythrocyte aggregation index (EAI), and erythrocyte sedimentation rate (ESR) were detected by fully automatic hematology analyzer.

PMID- 29166709 TI - [Effects of dexmedetomidine on myocardium of rats with severe burn at early stage]. AB - Objective: To investigate the effects of dexmedetomidine on myocardium of rats at early stage after severe burn. Methods: Twenty specific pathogen free male SD rats were immersed in 90 C hot water for 20 s, causing 30% total body surface area (TBSA) full-thickness scald (hereafter referred to as burn) on the back. And then they were divided into burn resuscitation group (BR) and burn resuscitation+ dexmedetomidine group (BRD) according to the random number table, with 10 rats in each group. Sodium lactate Ringer's solution (2 mL.kg(-1).%TBSA(-1)) were intraperitoneally injected into rats of both groups after burn. Dexmedetomidine with dose of 1 MUg/kg was intraperitoneally injected into rats of group BRD at the same time point. Another 5 rats in sham injury group (SI) were immersed in 37 C water bath causing sham injury, and fluid resuscitation of rats in group SI was the same as that in group BR. Five rats of group BR and BRD were respectively selected at post burn hour (PBH) 6 and 24. And then left ventricular end-systolic internal diameter (LVIDs), left ventricular end-diastolic internal diameter (LVIDd), ejection fraction (EF), and cardiac output (CO) were determined with small animal ultrasonic imaging system. Plasma levels of cardiac troponin (cTn) I and cTnT were detected by enzyme-linked immunosorbent assay, and morphological changes of myocardium were observed under optical microscope and transmission electron microscope (observed only at PBH 24). In rats of group SI, morphological change of myocardium was observed at PBH 24, and the other indexes were detected as above. Data were processed with one-way analysis of variance and SNK test. Results: At PBH 6, EF value of rats in group BR [(98.0+/-2.8) %] was obviously higher than that in group SI [(91.0+/-0.4)%, P<0.05]. The other 3 cardiac ultrasound indexes of rats in group BR were close to those in group SI (with P values above 0.05). Each cardiac ultrasound index of rats between groups BRD and SI was close at PBH 6 (with P values above 0.05). At PBH 24, LVIDs levels of rats in group BR [(0.66+/-0.59) mm] and group BRD[(0.69+/-0.27) mm] were obviously lower than LVIDs level of rats in group SI [(1.65+/-0.33) mm, with P values below 0.05]. LVIDd, EF, and CO levels of rats were close among 3 groups at PBH 24 (with P values above 0.05). At PBH 6, the plasma levels of cTnI [(17.40+/-1.59) ng/mL] and cTnT [(1 488+/-229) pg/mL] of rats in group BR were significantly higher than those in group SI [(1.84+/-0.92) ng/mL and (169+/-12) pg/mL, with P values below 0.01]. At PBH 6 in group BRD, the plasma level of cTnI of rats [(2.58+/-0.60) ng/mL] was close to that in group SI (P>0.05), and the plasma level of cTnT [(649+/-190) pg/mL] was higher than that in group SI (P<0.01). At PBH 24, the plasma levels of cTnI and cTnT of rats in group SI were close to those in groups BR and BRD (with P values above 0.05). At PBH 24, the plasma level of cTnI of rats in group BRD was obviously lower than that in group BR (P<0.01). At PBH 6, the myocardial structures of rats in group BR and group BRD were normal, which were close to myocardial structure of rats in group SI at PBH 24. At PBH 24, obviously damaged myocardial tissue, disorderly arrangement of myofilament, and seriously damaged mitochondria were observed in rats of group BR, which were significantly ameliorated in rats of group BRD. Conclusions: Dexmedetomidine can protect the myocardium of rats with severe burn at early stage. PMID- 29166711 TI - [Effects of caspase-1 inhibitor VX765 on cold-restraint stress-induced acute gastric ulcer in mice]. AB - Objective: To investigate the protective effects of caspase-1 inhibitor VX765 on gastric mucosa of mice with cold-restraint stress-induced acute gastric ulcer. Methods: Twenty-four specific pathogen free male C57BL/6J mice were divided into normal control group (NC), cold restrain group (CR), VX765 pre-treatment+ cold restrain group (VCR), and rabeprazole pre-treatment+ cold restrain group (RCR) according to the random number table, with 6 mice in each group. Mice in group NC were injected intraperitoneally with solution of 10 mL/kg dimethylsulfoxide (DMSO) and phosphate buffer solution (PBS). Mice in group CR were inflicted with acute gastric ulcer induced by cold-restraint stress 30 minutes after intraperitoneal injection of solution of DMSO and PBS. Mice in groups VCR and RCR were inflicted with acute gastric ulcer as above 30 minutes after intraperitoneal injection of solution of DMSO and PBS with dose of 12.5 MUmol/kg containing 10 mg VX765 and 40 mg/kg containing 20 mg rabeprazole, respectively. Four hour after cold-restraint stress, serum content of tumor necrosis factor alpha (TNF-alpha) and interleukin 6 (IL-6)was determined by enzyme-linked immunosorbent assay. Gross condition of gastric tissue was observed. Ulcer index was evaluated. Pathological change of gastric tissue was observed with HE staining. The relative expression of IL-1beta, IL-18, and cleaved-caspase-1 in gastric tissue were detected by Western blotting. Mice in group NC were detected as above at the same time point. Data were processed with one-way analysis of variance and Bonferroni test. Results: The serum content of TNF-alpha and IL-6 and the relative expression of cleaved-caspase-1, IL-1beta, and IL-18 in gastric tissue of mice in group NC were significantly lower than those in group CR (with P values below 0.01). The content of the above-mentioned inflammatory indexes in serum and gastric tissue of mice in group VCR was significantly lower than that in group CR (with P values below 0.01). There were no statistically significant differences in content of the above-mentioned inflammatory indexes in serum and gastric tissue of mice between groups RCR and CR (with P values above 0.05). The content of the above-mentioned inflammatory indexes in serum and gastric tissue of mice in group VCR was significantly lower than that in group RCR (with P values below 0.01). Surface of gastric mucosa was smooth and morphology of mucosal cells was normal with clear structure of mice in group NC. Multiple hemorrhage of gastric mucosa, disorderly arrangement of mucosal cells, and large number of inflammatory cell infiltration around necrotic tissue were observed in mice of group CR. Decreased number of gastric mucosa bleeding, intact mucosal structure, and small amount of inflammatory cell infiltration around necrotic tissue were observed in mice of groups VCR and RCR. The ulcer indexes of mice in groups NC, CR, VCR, and RCR were 0, 18.7+/-1.1, 6.3+/-1.5, and 8.2+/-1.3, respectively. The ulcer index of mice in group NC was significantly lower than that in the other 3 groups (with P values below 0.05). The ulcer indexes of mice in groups VCR and RCR were close (P>0.05), which were significantly lower than ulcer index of mice in group CR (with P values below 0.05). Conclusions: VX765 can effectively inhibit the activation of caspase-1, reduce production of inflammatory factor, and alleviate inflammatory response, which have protective effects on gastric mucosa of mice with cold-restraint stress-induced acute gastric ulcer. PMID- 29166710 TI - [Effects of hydrogen on the lung damage of mice at early stage of severe burn]. AB - Objective: To investigate the effects of hydrogen on the lung damage of mice at early stage of severe burn. Methods: One hundred and sixty ICR mice were divided into sham injury, hydrogen, pure burn, and burn+ hydrogen groups according to the random number table, with 40 mice in each group. Mice in pure burn group and burn+ hydrogen group were inflicted with 40% total body surface area full thickness scald (hereafter referred to as burn) on the back, while mice in sham injury group and hydrogen group were sham injured. Mice in hydrogen group and burn+ hydrogen group inhaled 2% hydrogen for 1 h at post injury hour (PIH) 1 and 6, respectively, while mice in sham injury group and pure burn group inhaled air for 1 h. At PIH 24, lung tissue of six mice in each group was harvested, and then pathological changes of lung tissue were observed by HE staining and the lung tissue injury pathological score was calculated. Inferior vena cava blood and lung tissue of other eight mice in each group were obtained, and then content of high mobility group box 1 (HMGB1) and interleukin-6 (IL-6) in serum and lung tissue was determined by enzyme-linked immunosorbent assay. Activity of superoxide dismutase (SOD) in serum and lung tissue was detected by spectrophotometry. After arterial blood of other six mice in each group was collected for detection of arterial partial pressure of oxygen (PaO(2)), the wet and dry weight of lung tissue were weighted to calculate lung wet to dry weight ratio. The survival rates of the other twenty mice in each group during post injury days 7 were calculated. Data were processed with one-way analysis of variance, LSD test and log-rank test. Results: (1) At PIH 24, lung tissue of mice in sham injury group and hydrogen group showed no abnormality. Mice in pure burn group were with pulmonary interstitial edema, serious rupture of alveolar capillary wall, and infiltration of a large number of inflammatory cells. Mice in burn+ hydrogen group were with mild pulmonary interstitial edema, alveolar capillary congestion accompanied by slight rupture and bleeding, and the number of infiltration of inflammatory cells was smaller than that in pure burn group. The lung tissue injury pathological scores of mice in sham injury group, hydrogen group, pure burn group, and burn+ hydrogen group were (0.7+/-0.5), (0.8+/-0.5), (6.1+/-1.0), and (2.8+/-0.8) points, respectively. The lung tissue injury pathological score of mice in pure burn group was significantly higher than that in sham injury group (P<0.001). The lung tissue injury pathological score of mice in burn+ hydrogen group was significantly lower than that in pure burn group (P<0.001). (2) At PIH 24, the content of HMGB1 and IL-6 in serum and lung tissue of mice in hydrogen group was close to that in sham injury group (with P values above 0.05). The content of HMGB1 and IL-6 in serum and lung tissue of mice in pure burn group was significantly higher than that in sham injury group (with P values below 0.001). The content of HMGB1 and IL-6 in serum and lung tissue of mice in burn+ hydrogen group was significantly lower than that in pure burn group (with P values below 0.001). (3) At PIH 24, the activity of SOD in serum and lung tissue of mice in hydrogen group was close to that in sham injury group (with P values above 0.05). The activity of SOD in serum and lung tissue of mice in pure burn group was significantly lower than that in sham injury group (with P values below 0.001). The activity of SOD in serum and lung tissue of mice in burn+ hydrogen group was significantly higher than that in pure burn group (with P values below 0.001). (4) At PIH 24, there was no statistically significant difference in PaO(2) among the mice in four groups (F=0.04, P>0.05). (5) At PIH 24, the ratios of lung wet to dry weight of mice in sham injury, hydrogen, pure burn, and burn+ hydrogen groups were 3.52+/-0.22, 3.61+/-0.24, 7.24+/-0.32, and 5.21+/-0.41, respectively. The ratio of lung wet to dry weight of mice in pure burn group was significantly higher than that in sham injury group (P<0.001). The ratio of lung wet to dry weight of mice in burn+ hydrogen group was significantly lower than that in pure burn group (P<0.001). (6) The survival rates of mice in sham injury group and hydrogen group during post injury days 7 were 100%. Compared with those in sham injury group, survival rates of mice in pure burn group from post injury days 3 to 7 were significantly decreased (with P values below 0.05). Compared with those in pure burn group, survival rates of mice in burn+ hydrogen group from post injury days 5 to 7 were significantly increased (with P values below 0.05). Conclusions: Hydrogen can significantly alleviate the infiltration of inflammatory cells and improve the pathological lesions of lung tissue of mice with severe burn. It has the effects of reducing inflammatory reaction and inhibiting oxidative stress, further showing the protective effect on the lung of burn mice. PMID- 29166712 TI - [Effects of endostatin pretreatment on fibrosis of human skin fibroblasts and the mechanisms]. AB - Objective: To explore the effects of endostatin pretreatment on fibrosis of human skin fibroblasts and the mechanisms. Methods: Human skin fibroblasts were routinely cultured in vitro, and then the cells of passage 3 to 5 were used in the following experiments. The cells were divided into blank control, endostatin, platelet-derived growth factor-BB (PDGF-BB), endostatin+ PDGF-BB, transforming growth factor-beta(1) (TGF-beta(1)), and endostatin+ TGF-beta(1) groups according to the random number table, with 3 wells in each group. Cells in blank control group were cultured with DMEM medium for 24 h. Cells in endostatin group were cultured with DMEM medium containing 5 MUg/mL endostatin for 24 h. Cells in PDGF BB group and TGF-beta(1) group were cultured with DMEM medium containing 200 ng/mL PDGF-BB and 10 ng/mL TGF-beta(1) for 24 h, respectively. Cells in endostatin+ PDGF-BB group were pretreated with DMEM medium containing 5 MUg/mL endostatin for 48 h and then cultured with DMEM medium containing 200 ng/mL PDGF BB for 24 h. Cells in endostatin+ TGF-beta(1) group were pretreated with DMEM medium containing 5 MUg/mL endostatin for 48 h and then cultured with DMEM medium containing 10 ng/mL TGF-beta(1) for 24 h. The content of type I collagen in the cell culture supernatant of three wells in each group was determined by enzyme linked immunosorbent assay. The protein expression levels of alpha-smooth muscle actin (alpha-SMA), PDGF receptor beta (PDGFRbeta), phosphorylated PDGFRbeta (p PDGFRbeta), and phosphorylated extracellular signal-regulated protein kinases 1/2 (p-ERK1/2) of three wells in each group were detected by Western blotting. Data were processed with one-way analysis of variance and SNK test. Results: (1) Compared with (5.05+/-0.29) pg/mL in blank control group, content of type I collagen in the cell culture supernatant of endostatin group [(4.72+/-0.37) pg/mL] was close to it (P>0.05), content of type I collagen in the cell culture supernatant of PDGF-BB group and TGF-beta(1) group [(8.60+/-0.57) and (9.20+/ 0.64) pg/mL, respectively] was higher (with P values below 0.05). Content of type I collagen in the cell culture supernatant of endostatin+ PDGF-BB group [(5.32+/ 0.17) pg/mL] was lower than that of PDGF-BB group (P<0.05), and content of type I collagen in the cell culture supernatant of endostatin+ TGF-beta(1) group [(5.41+/-0.20) pg/mL] was lower than that of TGF-beta(1) group (P<0.05). (2) Compared with those in blank control group, protein expression levels of alpha SMA, PDGFRbeta, p-PDGFRbeta, and p-ERK1/2 of cells in endostatin group showed no obvious differences (with P values above 0.05), while those in PDGF-BB and TGF beta(1) group were significantly higher (with P values below 0.01). Protein expression levels of alpha-SMA, PDGFRbeta, p-PDGFRbeta, and p-ERK1/2 of cells in endostatin+ PDGF-BB group and endostatin+ TGF-beta(1) group were significantly lower than those in PDGF-BB group and TGF-beta(1) group, respectively (with P values below 0.05). Conclusions: Pretreatment of endostatin can inhibit the fibrosis of human skin fibroblast and its transformation into myofibroblast, which may be related to the down-regulation of protein expression of p-PDGFRbeta, PDGFRbeta, and p-ERK.

PMID- 29166713 TI - [Advances in the research of molecular mechanism of negative pressure wound therapy in improving wound healing]. AB - Recently, negative pressure wound therapy (NPWT) is a rising technology to improve wound healing. In clinical application, it benefits fast debridement and wound close, limits infection, and promotes wound healing. It is an effective therapy for all kinds of acute or chronic wound. Currently, researches demonstrate that NPWT promotes angiogenesis, granulation tissue growth, and extracellular matrix remodeling through regulating the signaling of anti inflammatory cytokines, mechanicalreceptor and chemoreceptor, which is related to several growth factors and inflammatory factors. Here we focus on the recent advances in the mechanism of NPWT in promoting wound healing, looking forward to providing a review of NPWT and related researches.

PMID- 29166716 TI - [Current status of the long-term adherence to warfarin anticoagulation therapy in patients with non-valvular atrial fibrillation]. PMID- 29166717 TI - [Left atrial appendage volume is a valuable predictor of atrial fibrillation recurrence after radiofrequency catheter ablation]. AB - Objective: To investigate the association between the left atrial appendage (LAA) volume and atrial fibrillation (AF) recurrence after radiofrequency catheter ablation. Methods: We prospectively enrolled sixty-two patients with AF (40 cases with paroxysmal AF, 22 cases with persistent AF) who successfully underwent a first AF catheter ablation and had performed contrast-enhanced cardiac computed tomography (CT) prior to the procedure to measure LAA volumes in our hospital from January 2012 to August 2015. Circumferential pulmonary vein isolation was performed under the guidance of three-dimension mapping system (CARTO system). Linear ablation or ablation of complex fractioned atrial electrograms was also undertaken if necessary. All patients were followed up at the 3rd, 6th and 12th months after ablation by 24-hour ambulatory Holter monitoring, and were divided into the non-recurrence group (n=42) and the AF recurrence group (n=20). Univariate and multivariate Cox proportional hazards regression analysis were used to assess the factors related to AF recurrence. The receiver operating characteristic (ROC) curve was calculated to assess the best cut-off value of LAA volume to predict AF recurrence. Kaplan-Meier method was used to evaluate the rate of freedom from AF recurrence. Results: Mean LAA volume in all patients was (9.5+/-3.6)ml. AF recurrence occurred in 20 patients (32%) during the follow-up period. The LAA volume was significantly larger in the AF recurrence group than in the non-recurrence group ((11.5+/-3.8)ml vs. (8.3+/-3.1)ml, P=0.002). In the univariate regression analysis, LAA volume (HR=1.36, 95%CI 1.14-1.82, P<0.001), persistent AF (HR=4.43, 95%CI 1.52-12.06, P<0.001) and hypertension (HR=1.61, 95%CI 1.13-2.04, P=0.041) were risk factors of AF recurrence. However, multivariate regression analysis revealed that LAA volume (HR=1.32, 95%CI 1.12 1.51, P<0.001) and persistent AF (HR=4.22, 95% CI 1.48-11.05, P<0.001) were independent predictors for AF recurrence after ablation. The receiver operating characteristic (ROC) curve analysis revealed that a LAA volume >8.80 ml was associated with AF recurrence after ablation (sensitivity: 94% and specificity: 66%, area under the curve=0.76). Kaplan-Meier analysis showed a lower rate free from AF recurrence in the group with LAA volume >8.80 ml (P<0.001). Conclusion: Larger LAA volume is associated with AF recurrence after catheter ablation in patients with AF. A LAA volume greater than 8.80 ml could be used to predict AF recurrence after ablation.

AB - Objective: To compare the value of two 3D imaging reconstruction methods for left atria and pulmonary vein on guiding the catheter ablation for atrial fibrillation (AF). Methods: From January 2014 to January 2017, a total of 100 drug refractory paroxysmal AF patients were divided into left atria direct angiography group (n=50), and indirect angiography group (n=50). 3D CARTO system was applied for mapping and guiding the ablation procedure. Patients assigned to direct angiography group were treated as follows: intraoperative puncture of atrial septum, inject contrast agent directly into the left atrium, conduct left atrial and pulmonary venous rotation angiography, reconstruct three-dimensional image, integrate the image into real-time X-ray system to facilitate circumferential pulmonary vein isolation. Patients assigned into the indirect angiography group were treated as follows: inject contrast agent through the right ventricle, conduct delayed rotation angiography of the left atria and pulmonary vein to guide circumferential pulmonary vein fixation and ablation. The left atrial and pulmonary venous image acquisition, the operation and X-ray exposure time, the success rate and the incidence of complication of the two groups were compared. The patients were followed up for 3-6 months. Results: General clinical characteristics of the two groups were similar(all P>0.05). Ablation was successful in all 100 patients. The operation time[(112.0+/-21.4)min vs. (134.0+/ 24.3)min]and X-ray exposure time((10.7+/-4.7)min vs. (15.8+/-5.2)min)were significantly lower in direct angiography group than in indirect angiography group (both P<0.01). There was no significant difference between the two groups in the immediate (86%(43/50) vs. 82%(41/50), P=0.59) and short-term (76%(38/50) vs. 72%(36/50), P=0.65) success rate and complication rate (1 aneurysm in the direct angiography group, 1 pericardial tamponade in the indirect angiography group). In-hospital mortality was zero percent. Conclusion: It is safe and effective method to guide the radiofrequency catheter ablation of paroxysmal atrial fibrillation by reconstruction 3D image of left atrium and pulmonary vein. Compared with indirect angiography group, direct angiography group can improve the imaging quality of left atrium and pulmonary vein, decrease the X-ray exposure time of the ablation procedure. PMID- 29166719 TI - [Clinical characteristics and outcome comparison between atrial fibrillation patients underwent catheter ablation under general aesthesia or local anesthesia and sedation]. AB - Objective: To compare the outcome of radiofrequency catheter ablation under local anesthesia/sedation (S) or general anesthesia(GA) in atrial fibrillation patients. Methods: Data of 498 patients with atrial fibrillation undergoing radiofrequency catheter ablation in our departmentfrom January 2014 to December 2015 were retrospectively analyzed. Two hundred and twenty patients assigned to the GA group, the other 278 patients to the S group. Patients were followed clinically every 3 months within one year after procedure. Immediate electrocardiogram was performed in patients with palpitation or choking sensation in chest. The end point of the study was recurrence of any atrial tachyarrhythmia lasting >30 seconds in device interrogation, 24-hour Holter monitoring or 12-lead electrocardiogram after a single procedure. After the ablation procedure, a blanking period of 3 months was allowed according to the guidelines. Procedure time, radiofrequency time, fluoroscopy time, the detection of paroxysmal supraventricular tachycardia, the success rate and the complications were compared between the two groups. Results: There was no difference in the baseline characteristics between the two groups, such as age, gender, BMI, complications, LVEF, LAD (all P>0.05). The duration of procedure ((117.8+/-51.7)minutes vs.(115.4+/-36.9)minutes, P=0.79), duration of fluoroscopy((12.5+/-11.2)minutes vs. (10.4+/-10.2)minutes, P=0.35), duration of radiofrequency((40.1+/ 12.9)minutes vs. (48.6+/-44.3)minutes, P=0.48) were similar between the two groups (P>0.05). Compared with S group, discovery of the frequency of atrioventricular node reentrant tachycardia (AVNRT) was significantly lower in GA group (0 vs. 3.6%(10/278), P<0.01), but the difference disappeared with repeat electrophysiological examination when patients become conscious from GA(3.2%(7/220) vs. 3.6%(10/278), P=0.311). The difference of atrioventricular reentrant tachycardia (AVRT) was similar between the two groups(0.9%(2/220) vs. 0.7%(2/278), P=0.841). Compared with S group, reflection of vagus nerve was less in GA group (1.4%(3/220) vs. 8.6%(24/278), P=0.026). After following up of (356+/ 92) days, freedom from atrial fibrillation/atrial flutter/atrial tachyarrhythmia was similar between the two groups(77.9%(162/208) vs. 79.9%(215/269), P=0.818). Conclusion: General anesthesia is a promising method to atrial fibrillation ablation, in view of stable patient status and safety for the procedure. There is no difference in complications, recurrence of arrhythmia between the two groups, but detection rate of AVNRT is lower in GA group.

AB - Objective: To compare the long term safety and efficacy of the novel abluminal groove-filled biodegradable polymer sirolimus-eluting stent(Firehawk stent) and permanent polymer coating everolimus eluting stent(Xience V stent) for the treatment of coronary de novo lesions. Methods: This prospective, multi-center, non-inferiority, randomized control trial(TARGETI trial) was performed between August 2010 and April 2011, a total of 460 patients with primary, de novo, single vessel and single coronary lesion from 16 medical centers were enrolled. The diameter stenosis of target lesion was >=70%, and lesion length was<=24 mm. The patients were randomly assigned to treatment with Firehawk stent (Firehawk stent group) or Xience V stent (Xience V stent group) groups by a web-based allocation system and was stratified by center. The late lumen loss after 9 months, target lesion failure (TLF) which was a composite of cardiac death, target vessel myocardial infarction, or ischemia driven target lesion revascularization, patient-oriented composite endpoint (PoCE) which was a composite of all cause death, all cause myocardial infarction, or any revascularization, and stent thrombosis after 5 years were compared between the two groups. Results: (1) There were 2 patients without stent implantation dropped out of this trial. There were 227 patients in Firehawk stent group, and 231 patients in Xience V stent group. The baseline characteristics were similar between the two groups(all P>0.05). (2) The 9 months late lumen loss in Firehawk stent group was non-inferior to that in Xience V stent group ((0.13+/-0.24)mm vs. (0.13+/-0.18)mm, P=0.94). (3) A total of 442 (96.5%) patients completed 5 years clinical follow-up. There were no significant differences on 5-year TLF rate (6.0%(13/217) vs. 6.7% (15/225), P=0.77) and PoCE rate (12.0%(26/217) vs. 17.8% (40/225), P=0.09) between the Firehawk stent group and Xience V stent group. (4) Kaplan-Meier analysis showed that TLF rates between 1-5 years were similar in Firehawk stent group and Xience V stent group (5.7% and 6.6% respectively, HR=0.88, 95%CI 0.42-1.84, P=0.72). Land-Mark analysis showed that TLF rates bewteen 1-5 years were similar in Firehawk stent group and Xience V stent group (3.6% and 4.4% respectively, HR=0.83, 95%CI 0.34-2.00, P=0.67). Kaplan-Meier analysis showed that PoCE rates between 1-5 years were also similar in Firehawk stent group and Xience V stent group (11.4% and 17.3% respectively, HR=0.64, 95%CI 0.39-1.04, P=0.07). Land-Mark analysis showed that PoCE rates after 5 years were similar in Firehawk stent group and Xience V stent group (8.4% and 10.0% respectively, HR=0.66, 95%CI 0.40 1.10, P=0.11). (5) No stent thrombosis was documented in Firehawk stent group during the 5 years follow-up period, and there was 1 case of stent thrombosis in Xience V stent group after 3 years of stent implantation. Conclusion: TARGETI trial results of 5 years follow up indicate the novel Firehawk stent have a durable safety and efficacy profile which is comparable to the Xience V stent in treating patients with single de novo coronary lesion.

PMID- 29166721 TI - [A preliminary study on the relationship between idiopathic arrhythmia and cardiac magnetic resonance imaging defined cardiac features in patients with straight back syndrome]. AB - Objective: To retrospectively analyze the potential correlation between cardiac magnetic resonance (CMR) imaging and clinical features and idiopathic arrhythmia in patients with straight back syndrome (SBS). Methods: Patients receiving CMR imaging examination from April 2015 to March 2016 at our department (n=1 432) were screened, 76 patients met the diagnosis criteria of flat chest (anteroposterior diameter/transthoracic diameter (APD/TTD) ratio<0.37 at the T8 vertebra). After excluding 33 patients with structural heart disease, 43 SBS patients were divided into two groups: SBS without obvious morphological change in the heart (group A, n=19) and SBS with morphological change of the heart (group B, n=24). CMR images were analyzed, focusing the heart morphological changes induced by SBS. The clinical data were collected to comprehensively analyze the medical history, electrocardiogram and electrophysiological examination in order to observe the relationship between SBS induced heart morphological change and the arrhythmia type and origin. Results: There were 21 male patients in this cohort, mean age was (28.5+/-11.5) years (13-58 years). APD/TTD ratio was similar between the two groups (0.30+/-0.03 vs. 0.29+/-0.04, P>0.05). LVEF tended to be lower in group B than in group A ((47.48+/-12.77)%vs. (59.31+/-9.04)%, P>0.05) . In group B, there were 15 patients with left ventricular enlargement, 2 with left ventricular wall thickening, 5 with uncoordinated ventricular wall motion, 5 with tricuspid regurgitation, 3 with mitral regurgitation, 2 with myocardial fibrosis, 5 with increased trabecular and 16 with decreased left ventricular function. Direct compression sign of right ventricle (disappeared precordial fat tissue space, secondary right atria enlargement and tricuspid regurgitation) and left atria (with or without secondary left ventricular enlargement and mitral regurgitation) were evidenced in patients of group B. CMR revealed that the arrhythmia origin corresponded the compression site of the heart in 8 cases (42.1%) in group A and 13 cases (54.2%) in group B, not corresponded to the compression site in 6 patients (31.6%) in group A and in 7 patients (29.2%) in group B, not attributable in 5 patients (26.3%) in group A and 4 patients (16.7%) in group B. The percent of arrhythmia origin corresponded the compression site of the heart tended to be higher in group B as compared to group A (P>0.05). Conclusion: SBS can induce changes of cardiac morphology and cardiac function. SBS induced cardiac compression is linked with the development of arrhythmias and might be one of the reasons of arrhythmias in these patients. PMID- 29166722 TI - [Value of bedside echocardiography in diagnosis and risk assessment of in hospital death for patients with Stanford type A aortic dissection]. AB - Objective: To investigate the value of bedside echocardiography in diagnosis and risk assessment of in-hospital death of patients with Stanford type A aortic dissection. Methods: The clinical data of 229 patients with Stanford type A aortic dissection diagnosed by CT angiography in Zhongshan Hospital affiliated to Fudan University between January 2009 and January 2016 were retrospectively analyzed. The patients were divided into survival group(191 cases)and non survival group(38 cases)according to presence or absence of in-hospital death. The bedside echocardiography features were analyzed, and influence factors of in hospital death were determined by multivariate logistic regression analysis. Results: (1) Compared with the survival group, the non-survival group had lower surgery rate (60.52%(23/38) vs. 85.34%(163/191), P<0.01). Age, gender and Debakey classification were similar between survival group and death group (all P>0.05). (2) The bedside echocardiography results showed that prevalence of aortic valve involvement(65.79%(25/38) vs.34.03%(65/191), P<0.01) and severe aortic regurgitation (44.74%(17/38) vs. 14.14%(27/191), P<0.01) were significantly higher in non-survival group than in survival group. The non-survival group had larger aortic root diameter than the survival group ((55.5+/-6.4)mm vs. (42.3+/ 7.8)mm, P<0.01). There were no significant differences in pericardial effusion, expansion of aortic sinus, and left ventricular ejection fraction between survival group and non-survival group (all P>0.05). (3) The multivariate logistic regression analysis showed that aortic valve involvement(OR=3.275, 95%CI 1.290 8.313, P<0.05), aortic root diameter(OR=1.202, 95%CI 1.134-1.275, P<0.01), and surgery (OR=0.224, 95%CI 0.079-0.629, P<0.01) were independent risk factors for in-hospital death in patients with Stanford type A aortic dissection. Conclusions: Bedside echocardiography has significant diagnostic value for Stanford type A aortic dissection. Aortic valve involvement, enlargement of aortic root diameter and without surgery are independent risk factors for patients with Stanford type A aortic dissection.

AB - Objective: To observe the correlation between Nepsilon-carboxymethyl-Lysine (CML), the main component of advanced glycation end products and the calcification of the anterior tibial artery plaque in patients with diabetic foot post foot amputation. Methods: Sixty patients hospitalized for foot amputation operation due to diabetic foot from June 2012 to June 2016 in the Department of Orthopedics, Affiliated Hospital of Jiangsu University were prospectively recruited.The patients were categorized into mild stenosis (00.05). Compared with the NCM group, the early apoptosis rates were remarkably increased ((79.07+/-5.75)% vs.(4.57+/-3.45)%, P<0.05) in NCM+ H(2)O(2) group. Compared with the mimics group, the early apoptosis was significantly up-regulated in the mimics+ H(2)O(2) group ((30.27+/ 1.36)% vs.(5.13+/-3.21)%, P<0.05), which were further down-regulated in mimics+ H(2)O(2) group compared with the NCM+ H(2)O(2) group ((30.27+/-1.36)% vs.(79.07+/ 5.75)%, P<0.05). (3) Western blot results showed similar protein expression of Caspase-3, Bax and Bcl-2 between NCM group and mimics group(all P>0.05). Compared with the NCM group, the Caspase-3 and Bax protein expression was significantly increased in NCM+ H(2)O(2) group (all P<0.05), but the protein expression level of Bcl-2 was similar between the 2 groups(P>0.05). The Caspase-3 and Bax protein expression was markedly decreased, while Bcl-2 apparently increased in the mimics+ H(2)O(2) group compared with the NCM+ H(2)O(2) group(all P<0.05). Conclusion: Overexpression of miRNA-21 protects the C-kit(+) cardiac stem cells from apoptosis caused by oxidative stress through downregulating proapoptotic and upregulating the antiapoptotic proteins. PMID- 29166726 TI - [Interaction between TRPC1 and STIM1 in calcium sensing receptor mediated calcium influx and nitric oxide production in human umbilical vein endothelial cells]. AB - Objective: To investigate the interaction of Ca(2+) protein TRPC1 and STIM1 in extracellular Ca(2+) -sensing receptor (CaR)-induced extracellular Ca(2+) influx and the production of nitric oxide (NO). Methods: Human umbilical vein endothelial cells (HUVECs) were cultured and incubated with CaR agonist spermine (activating store-operates cation channels (SOC) and receptor-operated channels (ROC)), CaR negative allosteric modulator Calhex231 (blocking SOC, activating ROC) and ROC analogue TPA (activating ROC, blocking SOC), protein kinase C (PKC) inhibitor Ro31-8220, PKCs and PKCMU inhibitor Go6967(activate SOC, blocking ROC), respectively. The interaction of TRPC1 and STIM1 was determined using the immunofluorescence methods. The interaction between TRPC1 and STIM1 were examined by Co-immuno precipitation. The HUVECs were divided into: TRPC1 and STIM1 short hairpin RNA group (shTRPC1+ shSTIM1 group), vehicle-TRPC1+ vehicle-STIM1 group and control group. The cells were incubated with four different treatments under the action of above mentioned interventions, intracellular Ca(2+) concentration ([Ca(2+) ](i)) was detected using the fluorescence Ca(2+) indicator Fura-2/AM, the production of NO was determined by DAF-FM. Results: (1) The expression of TRPC1 and STIM1 proteins levels in HUVECs: Under the confocal microscope, TRPC1 and STIM1 protein expression showed masculine gender, both located in cytoplasm in the normal control group. Post incubation with Calhex231+ TPA, Ro31-8220 and Go6967, TRPC1 and STIM1 positioned in cytoplasm was significantly reduced, and the combined TRPC1 and STIM1 was also significantly reduced. (2) The interaction of TRPC1 and STIM1 in HUVECs: The relative ratios of Calhex231+ TPA+ Spermine+ Ca(2+) group, Ro31-8220+ Spermine+ Ca(2+) group and Go6976+ Spermine+ Ca(2+) group STIM1/TRPC1 and TRPC1/STIM1 were as follows: (25.98+/-2.17)% and (44.10+/ 4.01)%, (20.85+/-1.01)% and (46.31+/-3.47)%, (23.88+/-2.05)% and (39.65+/-2.91)%, which were significantly lower than those in the control group (100.00+/-4.66)% and (100.00+/-6.40)% and in the Spermine+ Ca(2+) group (106.04+/-2.45)% and (107.78+/-2.66)% (all P<0.05). (3) The influence of joint TRPC1 and STIM1 transfection to four different drugs treated HUVECs on [Ca(2+) ](i) and NO generation: The changes of two excitation fluorescence intensity ratio and NO net fluorescence intensity values were consistent, [Ca(2+) ](i) and NO net fluorescence intensity values were significantly lower in the experimental group than the control group and the vehicle group (all P<0.05), while which were similar between the vehicle group and control group (all P>0.05). Conclusions: Our results indicate that TRPC1 and STIM1 jointly regulate CaR-mediated Ca(2+) influx and nitric oxide generation in HUVECs in the form of binary complex. PMID- 29166727 TI - [Analysis on the trends in mortality following acute myocardial infarction from 1999 to 2015 in Tianjin of China]. AB - Objective: To explore the trends change in mortality following acute myocardial infarction (AMI) from 1999 to 2015 in Tianjin, China. Methods: AMI mortality data from 1999 to 2015 were obtained from Tianjin population based mortality surveillance system operated by the Tianjin Centers for Disease Control and Prevention (CDC), and population data of permanent residents were obtained from Tianjin Municipal Public Security Bureau. The trends change and affecting factors including gender, age, and geographic distribution on mortality following AMI were analyzed. Results: (1)The standardized mortality rate of AMI in Tianjin from 1999 to 2015 was 52.32/100 000 to 48.62/100 000. Adjusted AMI mortality rate from 1999 to 2013 was 52.32/100 000 to 73.72/100 000, indicating an increased trend(Z=32.15, P<0.001)with an annual percent change (APC) of 2.53%. Adjusted AMI mortality rate was decreased from 2013 to 2015: 73.72/100 000 to 48.62/100 000 (Z=-22.80, P<0.001), and APC was -19.07%. Above trends change was similar for male and female residents (all P<0.001). (2)The AMI standardized mortality rate of male was significantly higher than that of female during the 17 years. The AMI standardized mortality of male was significantly higher than that of female in<35, 35-44, 45-54, 55-64 and >=65 years old group, respectively. AMI mortality rate increased with age. (3)Except in the year of 2002 and 2003, the AMI mortality rate were significantly higher in rural residents than in urban residents during this study period (P<0.001). Adjusted AMI mortality in urban residents increased from 1999 to 2009(Z=8.05, P<0.001, APC=1.43%), and decreased in the year from 2009 to 2015 (Z=-18.71, P<0.001, APC=-6.32%). Adjusted AMI mortality in rural residents increased in the year of 1999 to 2013(Z=56.05, P<0.001, APC=5.84%), and decreased in the year of 2013 to 2015 (Z=-24.40, P<0.001, APC=-21.35%). Conclusions: Our results suggest that AMI mortality in Tianjin increased from 1999 to 2013, and decreased from 2013 to 2015, and male and rural residents have higher AMI mortality. Related prevention and intervention measures should be taken to decrease AMI mortality, especially for male and rural residents.

AB - Objective: To evaluate the efficacy and safety of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in prophylaxis neutropenia after chemotherapy in patients with lymphoma. Methods: This was a multicenter, single arm, open, phase IV clinical trial. Included 410 patients with lymphoma received multiple cycles of chemotherapy and PEG-rhG-CSF was administrated as prophylactic. The primary endpoint was the incidence of III/IV grade neutropenia and febrile neutropenia (FN) after each chemotherapy cycle. Meanwhile the rate of antibiotics application during the whole period of chemotherapy was observed. Results: 1Among the 410 patients, 8 cases (1.95%) were contrary to the selected criteria, 35 cases (8.54%) lost, 19 cases (4.63%) experienced adverse events, 12 cases (2.93%) were eligible for the termination criteria, 15 cases (3.66%) develpoed disease progression or recurrence, thus the rest 321 cases (78.29%) were into the Per Protocol Set. 2During the first to fourth treatment cycles, the incidences of grade IV neutropenia after prophylactic use of PEG-rhG-CSF were 19.14% (49/256) , 12.5% (32/256) , 12.18% (24/197) , 13.61% (20/147) , respectively. The incidences of FN were 3.52% (9/256) , 0.39% (1/256) , 2.54% (5/197) , 2.04% (3/147) , respectively. After secondary prophylactic use of PEG rhG-CSF, the incidences of IV grade neutropenia decreased from 61.54% (40/65) in the screening cycle to 16.92% (11/65) , 18.46% (12/65) and 20.75% (11/53) in 1-3 cycles, respectively. The incidences of FN decreased from 16.92% (11/65) in the screening cycle to 1.54% (1/65) , 4.62% (3/65) , 3.77% (2/53) in 1-3 cycles, respectively. 3The proportion of patients who received antibiotic therapy during the whole period of chemotherapy was 34.39% (141/410) . 4The incidence of adverse events associated with PEG-rhG-CSF was 4.63% (19/410) . The most common adverse events were bone pain[3.90% (16/410) ], fatigue (0.49%) and fever (0.24%) . Conclusion: During the chemotherapy in patients with lymphoma, the prophylactic use of PEG-rhG-CSF could effectively reduce the incidences of grade III/IV neutropenia and FN, which ensures that patients with lymphoma receive standard dose chemotherapy to improve its cure rate.

AB - Objective: To observe the efficacy and safety between Pegfilgrastim (PEG-rhG-CSF) and Recombinant human granulocyte colony stimulating factor (rhG-CSF) in hematological malignancy after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: 157 patients after allo-HSCT were enrolled in this study from June 2015 to November 2016. Two agents of G-CSF were used to stimulate hematopoietic recovery after transplantation. There were 65 cases in PEG-rhG-CSF and 92 cases in rhG-CSF groups. Patients in PEG-rhG-CSF group were given a single subcutaneous dose of 6 mg on the first day and +8 d, while cases in rhG-CSF group were given in dose of 5 MUg.kg(-1).d(-1) by subcutaneous injection from +1 d continuing to neutrophils more than 1.5*10(9)/L, and then the indicators and survival rates in two groups after transplantation were compared. Results: 1There were no significant differences of the neutrophil implantation time[13.5 (8-12) d vs 13 (9-24) d, P=0.393] and platelet implantation time [14 (9-160) d vs 14 (9 92) d, P=0.094] between PEG-rhG-CSF and rhG-CSF groups respectively. There were no significant differences in terms of neutropenia period (P=0.435) , number of cases who got fever during neutropenia (P=0.622) , and the median time of fever in neutropenia period (P=0.460) , respectively between the two groups. There were no significant differences of erythrocyte and platelet transfusions (P=0.074, P=0.059) within 1 month after transplantation. 2There were no significant differences with regard to the incidences of acute GVHD[23.1% (15/65) vs 34.8% (32/92) , P=0.115], chronic GVHD[20.0% (13/65) vs 32.6% (32/92) , P=0.081], II IVdegree of acute GVHD[30.0% (13/65) vs 30.4% (30/92) , P=0.287] and extensive chronic GVHD[9.2% (6/65) vs 20.7% (19/92) , P=0.135] between PEG-rhG-CSF and rhG CSF groups. 3There were no significant differences in terms of disease free survival (DFS) (62.5% vs 61.4%, P=0.478) and overall survival (OS) (67.4% vs 67.3%, P=0.718) between PEG-rhG-CSF and rhG-CSF groups. 4There was no significant difference of the non-relapse mortality (NRM) between PEG-rhG-CSF and rhG-CSF groups[20.5% (95%CI 11.4%-37.0%) vs 32.6% (95%CI 22.2%-47.9%) , P=0.141]. The relapse rate was not statistically significant[14.9% (95%CI 7.4%-29.8%) vs 10.0% (95%CI 5.0%-20.0%) , P=0.299]. Conclusion: Compared with rhG-CSF, PEG-rhG-CSF could reduce the times of injection. There were no differences in terms of hematopoietic recovery, the incidence of GVHD, relapse rate, DFS and OS rates after allo-HSCT between two groups.

AB - Objective: To evaluate efficacy of the BiRd regimen, a combination of clarithromycin, lenalidomide, and dexamethasone, in the treatment of patients with relapsed/refractory multiple myeloma (RRMM) . Methods: Patients with RRMM treated with BiRd between September 11, 2013 and August 1, 2016 at six centers were included to evaluate overall survival rate (ORR) , clinical benefit rate (CBR) , progression-free survival (PFS) , overall survival (OS) , as well as adverse events. Results: Of 30 patients with RRMM, 27 patients were evaluable, and ORR and CBR were 51.9% (14/27) and 66.7% (18/27) respectively, including 1 sCR (3.7%) , 3 CR (11.1%) , 3 VGPR (11.1%) , and 7 PR (25.6%) . In 13 patients with prior Rd, ORR and CBR were 38.5% (5/13) and 61.5% (8/13) respectively, of which 5 patients with >=MR carried high-risk cytogenetic[ (e.g.17p- or t (4;14) ] together with at least one of other adverse-prognostic cytogenetic (e.g.13q- and/or 1q21+) . In 24 patients with prior bortezomib-based therapy, ORR and CBR were 45.8 and 62.5%, respectively. With a median follow-up time of 14.9 (range 1.0-33.8) months, the median PFS and OS were 12.0 (95%CI 11.6-12.4) and 27.6 (95%CI 15.1-40.1) months, respectively. The BiRd regimen was well tolerated. Conclusion: The BiRd regimen is an effective and safety protocol for RRMM, including those carrying high-risk cytogenetic markers. PMID- 29166735 TI - [The specific cytotoxicities of chimeric antigen receptor-engineered T cells on different lymphomas]. AB - Objective: To investigate the specific cytotoxicities of the second and third generations of chimeric antigen receptor (CAR) -engineered T cells (CAR-T) on different lymphomas. Methods: CAR-Ts were prepared by lentivirus packaging and infection of T cells. CCK-8, ELISA and Lactate dehydrogenase cytotoxicity assay were applied to detect the proliferation capacity, the secretion level of inflammatory factor and the specific cytotoxicity. Flow cytometry assay showed the specific cytotoxicity and residual level of CAR-T in lymphomas of treated mice. Results: The results showed that the third generation CAR-T had greater capacity of the specific cytotoxicity and proliferation capacity than of the second generation CAR-T. But there was no prominent change of the secretion level of inflammatory factor. The specific cytotoxicity of the second generation CAR-T on highly aggressive lymphomas Raji was more prominent than in inert EHEB, but also could achieve satisfactory effect. The tumor burden in the mice injected with Raji was lower than in the mice injected with EHEB from nude mice experiment. But the residual level of CAR-T in the EHEB-injected mice was higher than in the Raji-injected ones. So the second generation CAR-T was more suitable for the treatment of indolent lymphoma. Conclusion: The second generation CD19 CAR-T could treat aggressive lymphoma in a relatively short period, while the second generation CD19 CAR-T need a longer time in vivo to achieve satisfactory curative effect on the noble lymphoma.

AB - Objective: To investigate the characteristics and prognostic factor of central nervous system (CNS) involvement in patients with hemophagocytic lymphohistiocytosis (HLH) . Methods: From January 2006 to October 2015, 152 patients with HLH, 88 patients had CNS involvement, their clinical data were collected, and survival was analyzed using the Kaplan-Meier life table method, univariate and multivariate Cox regression model analyses were applied to identify the risk factors of prognosis. Results: 157.9% patients complicated with neurological symptoms, cerebrospinal fluid abnormalities were observed in 37.0% patients, 57.5% patients had abnormal neuroradiology. 236 patients survived well, 3 patients lost to follow-up, 49 dead, 1 survival patient had epilepsy. 3The 3 year overall survival rate of 88 patients was 44%. 4abnormal CSF and unreceived IT bore a significant, independent adverse prognostic value (P<0.05) . Conclusion: CNS involvement in HLH has a high frequency and poor prognosis, few patients remained neurologic sequelae; abnormal CSF related to poor prognosis, positive intrathecal injections could improve the prognosis. PMID- 29166737 TI - [Clinical analysis of patients with hemophagocytic lymphohistiocytosis complicated with gastrointestinal bleeding]. AB - Objective: To explore the clinical features of patients with hemophagocytic lymphohistiocytosis (HLH) complicated with gastrointestinal bleeding. Methods: The clinical data of 52 patients with HLH diagnosed from January 2015 to February 2017 were analyzed retrospectively. Results: 1Of the 52 patients[including 36 cases of EBV related (69.2%) , 5 cases of lymphoma related (9.6%) , 3 cases of primary HLH (5.8%) , 3 cases of rheumatism related (5.8%) , 2 cases of tuberculosis related (3.8%) , 3 cases of unknown causes (3.8%) ], 32 cases were male (61.5%) and 20 cases female (38.5%) with a median age of 26 (6-64) years old. 2The overall survival rates at 1, 3, 6 and 12 months were 74.7%, 53.8%, 32.9% and 23.3% respectively. 3Multivariate analysis (logistic regression) showed thrombocytopenia (P=0.036) and other sites of hemorrhage (P=0.030) were risk factors of poor prognosis, and allogeneic hematopoietic stem cell transplantation (allo-HSCT, P=0.026) was the influence of good prognostic factor. Conclusion: HLH combined with gastrointestinal bleeding was an entity of disease with poor prognosis. Thrombocytopenia and other sites of bleeding had a significant negative impact on patients, allo-HSCT produced a significant positive impact on patients. PMID- 29166738 TI - [Expression characteristics and prognosis significance of miRNA-181a in acute myeloid leukemia with normal karyotype]. AB - Objective: To study the expression of miRNA-181a in acute myeloid leukemia (AML) patients with normal karyotype to probe its prognosis significance. Methods: The expression level of miRNA-181a in bone marrow mononuclear cells of 120 de novo AML patients with normal karyotype was detected by real time fluorescence quantitative PCR. The direct sequencing method was used to detect IDH1, IDH2, NPM1, FLT3-ITD, DNMT3A and CEBPalpha mutations in CN-AML patients after PCR. The relationship between miRNA-181a expression and gene mutation, the clinical parameters and prognosis were analyzed. Results: The rates of overall surviva1 (OS) in high expression and low expression groups were 25.0 months and 15.0 months, respectively (P<0.05) . Relapse free survival (RFS) in high expression and low expression groups were 21.4 months and 11.2 months, respectively (P<0.05) . Significantly higher level hemoglobin, complete remission rate and proportion of wild type NPM1 expression in the high expression of miRNA-181a group were observed when compared with the lower expression of miRNA-181a group (P<0.05) . Multivariate Cox regression analysis showed miRNA-181a overexpression was an independent prognostic factor for CN-AML (HR=2.219, 95%CI 1.601~2.432, P=0.018) . Conclusion: Higher expression of miRNA-181a was a good prognostic factor independent of clinical parameters and high frequency gene mutations, which implicated that the miRNA-181a expression level could be used as an important prognostic indicator of AML patients with normal karyotype. PMID- 29166739 TI - [Study of the effects and mechanism of all-trans retinoic acid on leukemic cell line U937 cells with NPM1 mutation]. AB - Objective: To investigate the effect and mechanism of all-trans retinoic acid (ATRA) on leukemic cell line U937 cells with NPM1 mutation. Methods: Human acute myeloid leukemia cell line U937 was explored, NPM1 mutated (A type) plasmids were transfected into U937 to form stable clones A1 and A2, which were identified by Western blot and Co-immunoprecipitation. The cell proliferation was measured by methylthiazolyl tetrazolium bromide (MTT) ; cell cycle and cell apoptosis were explored by flow cytometric; cell colony formation was measured by microscope count, the molecular pathways related to cell proliferation were measured by Western blot. Results: 1The cell proliferations of mutant A1 and A2 were inhibited significantly by 52.6% and 35.8% (P<0.05) , respectively under ATRA exposure. 2The percentages of G(0)/G(1) stage of mutant A1 and A2 increased by 20.1% and 35.8%, respectively under ATRA exposure. 3All the U937 leukemic cells were inhibited under ATRA exposure; the decreased percentages of vector, wild type and mutant NPM1 cells were 32.7%, 57.9% and 90.9% respectively. 4p-ERK decreased obviously after ATRA exposure in NPM1 mutated leukemic cells. 5More mutant NPM1 cells inclined to apoptosis under the exposure of ATRA and cytotoxic drugs than cytotoxic drugs alone, meanwhile more cells apoptosis occurred when ATRA was administrated after cytotoxic drugs exposure. Conclusions: ATRA could inhibit cell proliferation and colony formation, blocked the cell cycle in the G(0)/G(1) stage accompanied by the significant reduction of p-ERK in U937 leukemic cells with NPM1 mutation. Besides, ATRA could synergize with drugs to suppress the leukemic cells survival more effectively when ATRA was administered after the cytotoxic drugs exposure in U937 leukemic cells with NPM1 mutation. PMID- 29166740 TI - [Factors associated with early treatment response in adults with acute myeloid leukemia]. AB - Objective: To explore the factors influencing early treatment responses in adult with de novo acute myeloid leukemia (AML) . Methods: Data of consecutive newly diagnosed AML (non-acute promyelocytic leukemia) adults were analyzed retrospectively. To assess the impact of clinical characteristics at diagnosis and induction regimen on achieving morphologic leukemia-free state (MLFS) , blood counts and minimal residual leukemia (MRD, positive MRD defined as RQ-PCR WT1 mRNA >=0.6% and/or any level of abnormal blast population detected by flow cytometry) at the time of achieving MLFS. Results: 739 patients were included in this study. 406 (54.9%) patients were male, with a median age of 42 years (range, 18-65 years) . In the 721 evaluable patients, MLFS was achieved in 477 (66.2%) patients after the first induction regimen and 592 (82.1%) within two cycles. A total of 634 patients (87.9%) achieved MLFS, including 534 (84.2%) achieving a complete remission (CR, defined as MLFS with ANC >= 1*10(9)/L and PLT >= 100*10(9)/L) , 100 (15.8%) achieving a CRi (defined as MLFS with incomplete ANC or PLT recovery) , respectively. 260 (45.9%) patients of 566 (89.3%) who detected MRD at the time of achieving MLFS had positive MRD. Multivariate analyses showed that female gender, favorable-risk of SWOG criteria, IA10 and HAA/HAD as induction regimen were factors associated with achieving early MLFS. In addition, low bone marrow blasts, HGB >= 80 g/L, PLT counts<30*10(9)/L and mutated NPM1 without FLT3-ITD were factors associated with achieving MLFS after the first induction regimen; Negative FLT3-ITD mutation was factor associated with achieving MLFS within two cycles. PLT counts >=30*10(9)/L and IA10, IA8 or HAA/HAD as induction chemotherapy were factors associated with achieving CR. Female gender, favorable-risk of SWOG criteria, FLT3-ITD mutation negative, mutated NPM1 without FLT3-ITD were factors associated with negative MRD. Conclusions: Female gender, favorable molecular markers or cytogenetics, and standard-dose induction regimen were key factors associated with higher probability of early and deep responses in adults with AML. PMID- 29166741 TI - [The study of expression and prognostic value of CD123 in acute myeloid leukemia bone marrow blasts]. AB - Objective: To study the expression of CD123 in bone marrow (BM) blasts of acute myeloid leukemia (AML) patients to explore the relationship between CD123 expression and therapeutic response and prognosis. Methods: This study retrospectively analyzed expression and distribution of CD123 in BM blasts in 137 cases of newly diagnosed AML (excluded M(3)) , CD123 detected by flow cytometry>=20% was defined as positive, including 84 CD123(+) AML and 53 CD123(-) AML, efficacy and prognosis were compared between the two groups. Results: 1 Among 137 patients, 84 were in group CD123(+) (61.3%) , and 53 in group CD123(-) (38.7%) . All 137 patients were classified into risk groups based on cytogenetic and molecular biology abnormalities. No significant differences were seen between the three risk groups with regard to their CD123 levels (chi(2)=0.861, P=0.650) . Compared with CD123(-) group, the CD123(+) group had higher WBC[47.7 (1.0-264.0) vs 22.4 (0.7-211.0) , z=-2.592, P=0.010]. 2 The rates of first complete remission (CR1) and recurrence of CD123(+) group were 54.8% (46/84) and 50.8% (32/63) , respectively; and CD123(-) group were 73.6% (39/53) and 41.7% (20/48) , respectively. There was significant difference of CR1 between the two groups (chi(2)=5.121, P=0.027) , whereas no significant difference of the recurrence rate (chi(2)=0.911, P=0.340) . 3 The median dutations of OS between CD123(+) group and CD123(-) group were 20.0 (95%CI 13.1-26.9) months vs 44.0 (95%CI 23.6 47.3) months, respectively (chi(2)=5.874, P=0.015) ; The median durations of DFS were 7.8 (95%CI 1.4-14.1) months vs 18.6 (95%CI 0-39.7) months, respectively, no differences were observed between the two groups (chi(2)=2.939, P=0.086) . 4 CD123 retained an adverse prognosis value on DFS and OS within the intermediate group and patients <= 50 years older. Conclusions: CD123 widely expressed in AML patients, which was an independent risk factor for CR1 and OS, which implicating its important role in evaluating the induction chemotherapy response and prognosis of AML. PMID- 29166742 TI - [Allogeneic hematopoietic stem cell transplantation for the treatment of acute myeloid leukemia with primary thrombocytosis: three cases report and literatures review]. AB - Objective: To investigate the characteristics of the essential thrombocythemia (ET) cases transformed to the acute myeloid leukemia (AML) and the role of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of this disease. Methods: The clinical and laboratory characteristics of 3 ET cases before and after transformation and after allo-HSCT were retrospectively analyzed, meanwhile the related literatures were reviewed and discussed. Results: Case 1 was a male patient of 44 years old, whose PLT was 500*10(9)/L when firstly diagnosed ET. After 3 years the disease progressed into myelodysplastic syndrome (MDS) while WT1 expression increased from 77 (first visit) to 13 171 copies/10 000 ABL copies, at the same time chromosome changed dramatically. During the period of decitabine treatment the disease processed into AML. Case 2 was a male of 58 years old whose PLT was 2 100*10(9)/L when firstly diagnosed ET. The disease progressed to AML after 9 years, whose WT1 expression increased from 130 (first visit) to 3 222 copies/10 000 ABL copies, and he relapsed shortly after intensive chemotherapy. Case 3 was a male of 60 years old whose PLT was 900*10(9)/L when firstly diagnosed ET. The disease progressed to AML after 5 years, whose WT1 increased from 56 (first visit) to3 696 copies/10 000 ABL copies. Moreover leukemia spread to central nervous system (CNS) during chemotherapy. Before allo-HSCT, cases 1 did not achieve remission; case 2 relapsed after a short time of remission and case 3 transferred to CNS leukemia. All of the 3 cases underwent allo-HSCT successfully, and they all achieved completely remission, whose chromosome and gene mutation recovered negative. At the same time, CNS leukemia of case 3 disappeared. The median WT1 decreased to 50 copies/10 000 ABL copies. There was no severe complication during the median time of 5 months after allo-HSCT. Conclusions: The patients transformed to AML had poor prognosis, allo-HSCT was the only method that can cure the disease now.

PMID- 29166751 TI - Is there a glucose metabolic signature of spreading TDP-43 pathology in Amyotrophic Lateral Sclerosis? AB - BACKGROUND: Recently, four neuropathological stages of amyotrophic lateral sclerosis (ALS) with spreading of transactive response DNA-Binding Protein-43 pathology were described. Although 18F-FDG PET has been useful in diagnosis and prognosis of ALS patients, in vivo disease staging using glucose metabolic patterns across the different ALS stages have not been attempted so far. In this study, we investigated whether the discriminant brain regions of the neuropathological stage model can be translated to metabolic patterns for in vivo staging of ALS. Furthermore, we examined the correlation of these metabolic patterns with disease duration, the Revised ALS Functional Rating Scale (ALSFRS R) and the Forced Vital Capacity (FVC). METHODS: 146 ALS patients (age 66.0 +/- 11.0 y; 86M/60F) were divided into four metabolic stages depending on glucose metabolism in discriminant regions of neuropathological stages. 18F-FDG data were analysed voxel-based to compare local metabolic patterns between different stages. Additionally, correlation analyses were performed between pathologic stage and clinical parameters. RESULTS: Relative hypometabolism was present in regions known to be affected from the post- mortem pathological spread model, but relative hypermetabolism was also observed across the different ALS stages. In particular, stage 4 reflected a different frontotemporal pattern discordant with mere progression of stage 1-3, which may point to a potential different subgroup in ALS. Furthermore, metabolic stage correlated with disease duration (Spearman rho = -0.21, p = 0.01) and FVC (Spearman rho = -0.24, p = 0.04). CONCLUSIONS: The neuropathological ALS stages correspond to discriminative regional brain glucose metabolism patterns correlating with disease duration and forced vital capacity. Furthermore, metabolic stage 4 may represents a separate group of ALS progression towards frontotemporal dementia. PMID- 29166752 TI - Immunotherapy treatment: an issue for metabolic response. AB - Since the beginning of second decade of last century, when it was introduced in many oncologic scenarios, immunotherapy has become an important tool in the management of a growing number of cancers. Immunotherapy for cancer appears to be useful, improving not only progression free survival but also overall survival, thus achieving the goal that many advanced cancers, previously considered without effective treatment options, have now become successfully treatable. However, considering the relatively recent introduction of these drugs in clinical scenarios and the continuous release of new drugs, there is a lack of large validated clinical experiences and many issues are today debated amongst which the evaluation of the response to immune-therapy. Engaging the host immune system in fighting against cancer is an energy-consuming process, requiring T-cell recruiting; this process, named "pseudo-progression," sometimes produces an increase of both dimensional and metabolic ratio of the lesions, as well as the appearance of "new lesions." This behavior, always considered as undisputed progressive disease when traditional chemotherapy is employed, should be carefully considered in the field of immunotherapy, where the phenomenon of "flare" followed by regression of the disease can occur. In this paper, Authors analyzed the best available evidence in this field, reviewed the most important issues concerning the development of immunotherapy, and addressed evidence and concerns about the evaluation of response when using immunotherapy drugs, in terms of both radiological and nuclear medicine criteria. PMID- 29166753 TI - Interventional locoregional treatment and metabolic response: advantages of using PET/CT in the evaluation of response to treatment. AB - INTRODUCTION: Interventional oncology locoregional therapies are validated treatment modalities for primary and secondary tumors in liver, lung, kidney and bone. At this time, there is no accordance in the choice of imaging modality to assess treatment response. Morphological imaging and RECIST 1.1 criteria based on size variation are limited by several critical points. On the other hand the role of functional imaging, in particular by [18F]-fluorodeoxyglucose ([18F]-FDG) positron emission tomography (PET), in both staging and response evaluation of locoregional treatments remains unclear because of the heterogeneous nature of available data. The aim of this paper was to summarize the available literature illustrating the state of art of metabolic evaluation of response after locoregional therapies in the three major organs of interest: liver, lung and bone. EVIDENCE ACQUISITION: Medline database was searched for relevant original paper evaluating the role of [18F]-FDG PET in interventional oncology treatment published up to June 2017 excluding case reports. EVIDENCE SYNTHESIS: Finally 41 studies papers evaluating the role of [18F]-FDG PET in both staging and in response evaluation of locoregional treatments focused on liver tumoral lesions (N.=29), on lung lesions (N.=10) and on bone lesions (N.=2) were considered for this review. CONCLUSIONS: PET/CT appears to perform well in the assessment of response to interventional therapies compared to conventional imaging, not only in terms of response evaluation but also as a possible prognostic tool. Nevertheless further prospective, homogenous studies are required to confirm these data, in particular for lung and bone lesions. PMID- 29166754 TI - Advances in oncological treatment: limitations of RECIST 1.1 criteria. AB - RECIST 1.1 criteria are the standard for the response assessment of most solid tumors on computed tomography (CT). Nevertheless, the emergence of new classes of treatment in the lasts decades has brought new challenges in the evaluation of response. A PubMed online database literature search was performed in order to identify papers in English with full text available published up to September 2017. Some oncologic treatments, such as antiangiogenic agents, immunotherapy and local treatments, have proven to be effective despite atypical patterns of response. In patients undergoing these treatments, size-based evaluations, such as RECIST1.1, show some limitations, since they often underestimate the response. Some modified criteria have been proposed to improve the response assessment in several specific settings, such in gastrointestinal stromal tumors treated by antiangiogenic agents, hepatocellular carcinoma treated by local ablation or solid tumors treated by immunotherapy. New techniques of image analysis and imaging modalities other than CT, such as magnetic resonance imaging and positron emission tomography, may provide additional information and amend some of the limitations of size-based criteria. The emergence of new treatment paradigms and the increasing trend toward personalizing treatment should be associated with a concomitant evolution of response assessment, in both research and clinical settings.

AB - Giant cell arteritis (GCA) and Takayasu's arteritis (TA) are large vessel vasculitis (LVV) primarily affecting the aorta and its major branches, mainly differentiated by the onset age (>50 years GCA and <40 years TA). In addition, temporal artery involvement and polymyalgia rheumatica are typical features of GCA, but not TA. Imaging techniques are required to secure the diagnosis of large vessel vasculitides, and to monitor the disease course. Both morphological and metabolic imaging are involved. Morphological imaging is represented mainly by computerized tomography (CT), CT angiography, magnetic resonance (MR), MR angiography, color-Doppler sonography (CDS) and high-resolution CDS. Metabolic aspects of inflammatory process in LVV can be well studied by positron emission tomography/computed tomography with [18F]deoxyglucose ([18F]FDG PET/CT). It has an important increasing role in diagnosis, extent assessment and disease activity and therapy response evaluation. In the near future the concomitant development of increasingly powerful PET/CT scanners, of new radiopharmaceuticals more specific for inflammation, and of new PET/MRI hybrid scanners probably will lead to a further new step forward in the diagnosis and clinical management of LVV.

PMID- 29166758 TI - Clinical significance of anti-dense fine speckled 70 antibody in patients with fibromyalgia. AB - Background/Aims: Fibromyalgia (FM) is a common rheumatologic disease characterized by chronic widespread pain, along with various clinical manifestations including atypical autoimmune characteristics. Despite its high prevalence, there remain no approved laboratory tests to identify specific manifestations of FM, or to rule out FM from other rheumatic diseases. Anti-dense fine speckled 70 (anti-DFS70) antibodies were initially identified as a form of anti-nuclear antibodies in a patient with interstitial cystitis. Anti-DFS70 antibodies are found in <= 10% of healthy individuals, but have suggestive negative association with autoimmune diseases; however, the clinical significance of these autoantibodies in FM patients remains poorly understood. Methods: We examined 39 patients with FM, along with 17 patients with systemic lupus erythematosus (SLE), and 19 healthy individuals (HI). Patients were compared based on physical measurements, disease duration, tender point counts, FM Impact Questionnaire (FIQ) scores, visual analog scale (VAS) for pain, somatic symptoms, and anti-DFS70 antibodies. Results: Levels of anti-DFS70 antibodies were significantly higher in the FM and HI groups than in those with SLE. Both anti DFS70 antibodies and VAS scores were positively correlated with FM. Within the FM group, patients with arthralgia had higher anti-DFS70 antibody values compared to those without arthralgia (p = 0.024); antibody levels were also higher in patients with sleep disturbances relative to those without sleep issues (p = 0.024). In contrast, there were no correlations between anti-DFS70 antibodies and age, body mass index, disease duration, tender point counts, FIQ, short-form health survey results, or other clinical manifestations. Conclusions: Anti-DFS70 antibodies may represent a useful biomarker for differentiating between FM and other autoimmune diseases. The levels of anti-DFS70 antibodies were also significantly higher among patients with arthralgia and sleep disturbances. Further investigations are necessary to evaluate the relationships between anti DFS70 antibodies and other cytokines as a predictive marker for pain. PMID- 29166759 TI - Magnetic resonance imaging-assessed synovial and bone changes in hand and wrist joints of rheumatoid arthritis patients. AB - Background/Aims: Magnetic resonance imaging (MRI) is a sensitive and useful method for the detection of synovitis and joint destruction in rheumatoid arthritis (RA) patients. However, the patterns of MRI-detected bone erosion, bone marrow edema (BME), synovitis, and tenosynovitis have received insufficient attention. Therefore, this study evaluated the patterns of bone erosion, BME, synovitis, and tenosynovitis, and calculated the RA-MRI score (RAMRIS) of patients with RA at the carpal and metacarpophalangeal (MCP) joints using MRI. Methods: MRI datasets from 43 RA patients were analyzed. All patients had undergone MRI of one wrist. In addition, 36 patients had MCP joint images taken, and three had also received MRI of the contralateral wrist and MCP joints. The MR images were evaluated for bone erosion, BME, and synovitis in consensus by two blinded readers according to the Outcome Measures in Rheumatology Clinical Trials (OMERACT) RAMRIS. The MRI-detected tenosynovitis was evaluated based on Haavardsholm's tenosynovitis score. Results: The capitate, lunate, triquetrum, and hamate bones were the most common sites of erosion and BME and showed the highest RAMRIS erosion and BME scores. Moreover, MRI-detected tenosynovitis was present in 78.3% of all patients with RA, and the extensor compartment 4 and flexor digitorum profundus and superficialis were frequently affected. Conclusions: This study identified the distribution and prevalence of MRI detected bone erosion, BME, synovitis, and tenosynovitis of the wrist and MCP joints in RA patients. The patterns of the MRI-detected abnormalities may help to select sites for the application of MRI protocols in clinical trials and practice.

AB - BACKGROUND/AIMS: Elderly patients (>= 80 years) with colorectal cancer (CRC) tend to avoid active treatment at the time of diagnosis despite of recent advances in treatment. The aim of this study was to determine treatment propensity of elderly patients aged >= 80 years with CRC in clinical practice and the impact of anticancer treatment on overall survival (OS). METHODS: Medical charts of 152 elderly patients (aged >= 80 years) diagnosed with CRC between 1998 and 2012 were retrospectively reviewed. Patients' clinical characteristics, treatment modalities received, and clinical outcome were analyzed. RESULTS: Their median age was 82 years (range, 80 to 98). Of 152 patients, 148 were assessable for the extent of the disease. Eighty-two of 98 patients with localized disease and 28 of 50 patients with metastatic disease had received surgery or chemotherapy or both. Surgery was performed in 79 of 98 patients with localized disease and 15 of 50 patients with metastatic disease. Chemotherapy was administered in only 24 of 50 patients with metastatic disease. Patients who received anticancer treatment according to disease extent showed significantly longer OS compared to untreated patients (localized disease, 76.2 months vs. 15.4 months, p = 0.000; metastatic disease, 9.9 months vs. 2.6 months, p = 0.001). Along with anticancer treatment, favorable performance status (PS) was associated with longer OS in multivariate analysis of clinical outcome. CONCLUSION: Elderly patients aged >= 80 years with CRC tended to receive less treatment for metastatic disease. Nevertheless, anticancer treatment in patients with favorable PS was effective in prolonging OS regardless of disease extent. PMID- 29166761 TI - Full-blown hyperparathyroidism. PMID- 29166762 TI - A portable high-intensity focused ultrasound system for the pancreas with 3D electronic steering: a preclinical study in a swine model. AB - PURPOSE: The aim of this animal study was to evaluate the safety and feasibility of a portable, ultrasonography-guided, high-intensity focused ultrasound (USg HIFU) system to treat the pancreas. METHODS: Eight swine were included. Using a portable HIFU device (ALPIUS 900, Alpinion Medical Systems), ablations were performed on the pancreas in vivo. Different acoustic intensities were applied (1.7 kW/cm2 or 1.5 kW/cm2 , n=2 [group A for a pilot study]; 1.5 kW/ cm2 , n=3 [group B]; and 1.2 kW/cm2 , n=3 [group C]). Magnetic resonance imaging (MRI) was performed immediately (group A) or 7 days (groups B and C) after HIFU treatment. In groups B and C, serum amylase and lipase levels were measured on days 0 and 7, and performance status was observed every day. Necropsy was performed on days 0 (group A) or 7 (groups B and C) to assess the presence of unintended injuries and to obtain pancreatic and peripancreatic tissue for histological analysis. RESULTS: Ablation was noted in the pancreas in all swine on MRI, and all pathologic specimens showed coagulation necrosis in the treated area. The mean ablation areas on MRI were 85.3+/-38.1 mm2, 90.7+/-21.2 mm2, and 54.4+/-30.6 mm2 in groups A, B, and C, respectively (P>0.05). No animals showed evidence of complications, except for one case of a pseudocyst in group B. CONCLUSION: This study showed that pancreas ablation using a portable USg-HIFU system may be safe and feasible, and that coagulation necrosis of the pancreas was successfully achieved with a range of acoustic intensities.

PMID- 29166764 TI - Merkel Cell Carcinoma Metastatic to Pleural Fluid: A Case Report. AB - Merkel cell carcinoma (MCC) is a rare aggressive neuroendocrine carcinoma of the skin that shows locoregional or distant metastasis. Metastasis of MCC to body cavity effusion is extremely rare; only three cases have been reported so far. Metastatic MCC in effusion cytology shows small blue round cells with fine stippled chromatin like other small blue round cell tumors such as small cell lung carcinoma or lymphoma. The diagnosis of metastatic MCC can grant patients good chances at recently advanced therapeutic options. Here, we present a case of metastatic MCC to pleural effusion with characteristic single file-like pattern. PMID- 29166765 TI - Metal-free, Regio-, and Stereo-Controlled Hydrochlorination and Hydrobromination of Ynones and Ynamides. AB - We developed an atom-economical and metal-free method for the regio- and stereo selective hydrohalogenation of ynones and ynamides using easy to handle DMPU/HX (X = Br or Cl) reagents. The reaction operates under mild conditions and a range of functional groups is well tolerated. We propose that the hydrohalogenation of ynones gives the anti-addition products via a concerted multimolecular AdE3 mechanism and that the hydrohalogenation of ynamides produces the syn-addition products via a cationic keteniminium intermediate. PMID- 29166766 TI - Highly Active Graphene Oxide-Supported Cobalt Single-Ion Catalyst for Chemiluminescence Reaction. AB - Graphene- or graphene oxide (GO)-supported metallic nanoparticles and single metal atom as potentially effective catalysts for chemical reactions have recently received extensive research interests. However, metal utilization in nanoparticle catalysts is limited and metal atoms readily drift on the graphene surface and consequently form aggregated large particles, making practical applications limited. Here, we report metal ions directly immobilized on GO as a novel GO-supported single-ion catalyst for chemiluminecence (CL) reactions. It is found that GO-supported cobalt ions with good stability could catalyze strongly luminol-H2O2 and lucigenin-H2O2 CL reactions, accompanied by dramatically enhanced CL emission. Theoretical studies reveal that the coupling between Co2+ and GO induces effective polarization charges, improving chemical activity of the reaction site, which promotes the generation of intermediate radicals and accelerates the CL reactions. This work may be generalized to other GO-supported metal ions as catalysts for a wide range of chemical reactions. The developed GO supported cobalt single-ion nanocomposites as nanointerfaces may find future applications in CL bioassays. PMID- 29166767 TI - Effectiveness of Oral Rinsing Solutions on Mucus, Odor, and Plaque in the Hospitalized Elderly in Taiwan. AB - This quasi-experimental and pretest-posttest study was conducted in Taiwan. The effectiveness of three types of oral rinsing solutions (normal saline, 0.2% chlorhexidine [CHX], and boiled water) was compared among 120 elderly patients (40 patients per group). Data on oral mucus, odor, and plaque were collected at admission on Day 1 (Time [T] 0), Day 4 (T1), Day 7 (T2), and Day 10 (T3). The results showed that the oral health condition in terms of mucus, plaque, and odor improved significantly over time. The effect for the oral condition did not differ significantly among the three groups, except for oral odor. At T2, the CHX group experienced higher oral odor than did the boiled water group (Solutions * Time interaction, F = 3.967, p = .002). Boiled water appears to be a safe and effective oral rinsing solution for hospitalized elderly patients. PMID- 29166768 TI - Active parents, active children: The importance of parental organized physical activity in children's extracurricular sport participation. AB - This study investigated whether parental participation in organized and unorganized physical activity (PA) was associated with children's participation in extracurricular sport. The sample comprised 834 parents and their children (aged 6-10 years), living in central Portugal. Questionnaires assessed parental PA (organized and unorganized) and extracurricular sport participation in children (number of sports and frequency of participation). Multinomial logistic regression was applied to assess associations between parental and child physical behaviors. Having both parents active was significantly associated with frequent participation in more sports both in girls and boys but a strong relation according to gender was found. The odds of boys practicing more than one sport and more times per week were higher if they had an active father. Girls with physically active mothers, particularly with mothers practicing organized PA in a regular way, were engaged in more sports and practiced sport more times per week. The type of PA practiced by the parents was not related to boys' participation in sport. Future interventions should be family-based and focus on the promotion of higher levels of parental PA, including organized, in order to improve their children's active behaviors. PMID- 29166769 TI - Economic evaluation of a nurse-led home and clinic-based secondary prevention programme to prevent progressive cardiac dysfunction in high-risk individuals: The Nurse-led Intervention for Less Chronic Heart Failure (NIL-CHF) randomized controlled study. AB - OBJECTIVE: The objective of this study was to assess the cost-effectiveness of a long-term, nurse-led, multidisciplinary programme of home/clinic visits in preventing progressive cardiac dysfunction in patients at risk of developing de novo chronic heart failure (CHF). METHODS: A trial-based analysis was conducted alongside a pragmatic, single-centre, open-label, randomized controlled trial of 611 patients (mean age: 66 years) with subclinical cardiovascular diseases (without CHF) discharged to home from an Australian tertiary referral hospital. A nurse-led home and clinic-based programme (NIL-CHF intervention, n = 301) was compared with standard care ( n=310) in terms of life-years, quality-adjusted life-years (QALYs) and healthcare costs. The uncertainty around the incremental cost and QALYs was quantified by bootstrap simulations and displayed on a cost effectiveness plane. RESULTS: During a median follow-up of 4.2 years, there were no significant between-group differences in life-years (-0.056, p=0.488) and QALYs (-0.072, p=0.399), which were lower in the NIL-CHF group. The NIL-CHF group had slightly lower all-cause hospitalization costs (AUD$2943 per person; p=0.219), cardiovascular-related hospitalization costs (AUD$1142; p=0.592) and a more pronounced reduction in emergency/unplanned hospitalization costs (AUD$4194 per person; p=0.024). When the cost of intervention was added to all-cause, cardiovascular and emergency-related readmissions, the reductions in the NIL-CHF group were AUD$2742 ( p=0.313), AUD$941 ( p=0.719) and AUD$3993 ( p=0.046), respectively. At a willingness-to-pay threshold of AUD$50,000/QALY, the probability of the NIL-CHF intervention being better-valued was 19%. CONCLUSIONS: Compared with standard care, the NIL-CHF intervention was not a cost-effective strategy as life-years and QALYs were slightly lower in the NIL-CHF group. However, it was associated with modest reductions in emergency/unplanned readmission costs. PMID- 29166770 TI - Maltreatment, Coping, and Substance Use in Youth in Foster Care: Examination of Moderation Models. AB - Child maltreatment is associated with negative outcomes such as substance use (SU). This study tested relations among maltreatment history, coping behavior, and SU behavior in youth residing in foster care. Participants were 210 youth ( Mage = 12.71 years; SD = 2.95) in foster care who completed self-report measures through an audio computer-assisted self-interview program. Using a structural equation modeling framework and latent measurement constructs, positive associations were identified between maltreatment at baseline and coping behavior outcomes as well as SU behavior outcome approximately 4.5 months later. Specifically, greater severity and chronicity of maltreatment was associated with greater SU behavior as well as indirect action, prosocial, and asocial coping behavior. Maltreatment was not significantly related to direct action coping behavior. In moderation tests, only asocial coping provided a significant interaction effect for SU behavior outcomes; SU behavior did not moderate pathways between maltreatment and coping behavior. For youth in foster care, the coping approach may be varied and relate differentially to SU behavior outcomes, with asocial approaches to coping acting as a buffer for the maltreatment/SU relation. Additionally, SU remains an important target for intervention and prevention in youth residing in foster care. PMID- 29166771 TI - The effects of yoga on stress and psychological health among employees: an 8- and 16-week intervention study. AB - BACKGROUND: The stresses of modern work life necessitate effective coping strategies that are accessible and affordable to the general public. Yoga has been found to reduce stress in clinical samples, but studies are needed to examine standard gym yoga classes among functional individuals. OBJECTIVES: This study investigated the effects of 8- and 16-week gym yoga on stress and psychological health. DESIGN AND METHOD: Ninety individuals reporting moderate-to high stress were randomly assigned to 16 consecutive weeks of yoga, or to a waitlist crossover group who did not practice yoga for 8 weeks then practiced yoga for 8 weeks. Stress and psychological health variables were assessed at baseline, 8 weeks, and 16 weeks. RESULTS: Significant reductions in stress and all psychological health measures were found within the Yoga group over 16 weeks. When compared to the control group, yoga practitioners showed significant decreases in stress, anxiety, and general psychological health, and significant increases in well-being. The group who did not practice yoga showed significant decreases in stress, anxiety, depression, and insomnia after they crossed over and practiced yoga for 8 weeks. CONCLUSIONS: Gym yoga appears to be effective for stress amelioration and promotion of psychological health among workers experiencing stress.

AB - The objective of this study was to investigate the biological activities of Algerian algae, Sargassum vulgare, Cladostephus hirsutus and Rissoella verruculosa. Antimicrobial activity of the crude extracts and their fractions was assessed using the disc diffusion assay, the minimum inhibitory concentration and the minimum bactericidal concentration. Antiparasitic activity was studied in vitro against the blood stream forms of Trypanosoma brucei brucei and the intraerythrocytic stages of Plasmodium falciparum. Ethyl acetate (EA) fractions of the three tested algae showed more potent antimicrobial activity against S. aureus (7-14.5 mm) and B. cereus (7-10.75 mm), MIC values ranged from 0.9375 to 7.5 mg mL-1 and MBC values > 15 mg mL-1. Concerning the antiparasitic activity, EA factions of S. vulgare (IC50 = 9.3 MUg mL-1) and R. verruculosa (IC50 = 11.0 MUg mL-1) were found to be more effective against T. brucei brucei, whereas the three EA fractions were little active against P. falciparum. PMID- 29166773 TI - A simple polymer electrolyte membrane system for enrichment of low-level tritium (3H) in environmental water samples. AB - Tritium (3H) is an essential tracer of the Earth's water cycle; yet widespread adoption of tritium in hydrologic studies remains a challenge because of analytical barriers to quantification and detection of 3H by electrolytic pre concentration. Here, we propose a simple tritium electrolytic enrichment system based on the use of solid polymer electrolyte membranes (PEMs) that can be used to enrich 3H in 250-3000 mL environmental water samples to a 10-mL final volume. The IAEA PEM-3H system reported here can produce high enrichment factors (>70 fold) and, importantly, removes some of the deterrents to conventional 3H enrichments methods, including the use of toxic electrolysis and neutralization chemicals, spike standards, a complex electrolysis apparatus that requires extensive cooling and temperature controls, and improves precision by eliminating the need for tracking recovery gravimetrics. Preliminary results with varying operating conditions show 3H enrichments to 70-fold and higher are feasible, spanning a wide range of tritium activities from 5 to 150 TU with a precision of ~4.5 %. Further work is needed to quantify inter-sample memory and to establish lower 3H detection limits. The IAEA PEM-3H system is open source, with 3-D CAD and design files made freely available for adoption and improvement by others. PMID- 29166774 TI - A syringic acid derivative and two iridoid glycosides from the roots of Stachys geobombycis and their antioxidant properties. AB - A new derivative of syringic acid, stageobester A (1) and two iridoid glycosides which including a new one, stageoboside A (2), were isolated from the roots of Stachys geobombycis. Their structures were elucidated on the basis of spectroscopic methods, including extensive NMR and MS spectra. In addition, all the isolates were tested for their antioxidant capacity. Compounds 1 and 2 showed moderate antioxidant activities against DPPH radical, with IC50 values of 113.33 +/- 1.53 and 40.33 +/- 2.08 mg/L, respectively. PMID- 29166775 TI - Individualized Levels System and Systematic Stimulus Pairing to Reduce Multiply Controlled Aggression of a Child With Autism Spectrum Disorder. AB - Research has shown that physical aggression is common in individuals with autism spectrum disorder (ASD). Interventions for multiply controlled aggression may be complex and difficult to implement with fidelity. As a result, the probability of treatment efficacy for this class of behavior may suffer. We designed an individualized levels system to reduce the physical aggression of an 11-year-old female with ASD. We then employed a systematic stimulus pairing procedure to facilitate generalization. Results suggest individualized levels systems can suppress multiply controlled aggression and that systematic stimulus pairing is an effective way to transfer treatment effects from trained therapists to caregivers. PMID- 29166776 TI - The polysaccharide extracts from the fungi Coprinus comatus and Coprinellus truncorum do exhibit AChE inhibitory activity. AB - The polysaccharide (PSH) extracts from the edible mushroom species Coprinus comatus and Coprinellus truncorum were screened in liquid for their acetylcholinesterase inhibitory (AChE) activity. Both extracts were found to display inhibition of the aforementioned enzyme reaching similar IC50 values of 0.62 +/- 0.07 and 0.61 +/- 0.03 mg/mL, respectively. According to the means of FTIR spectroscopy, these PSH extracts mostly contained beta-glucans. However, the presence of some proteins and polyphenolics as minor ingredients were also detected. Compared with existing literature data for anti-AChE activity of the sugar samples, the findings within this study may be treated as a profound bioactivity. Consequently, this study puts some light on the possible use of the screened macrofungi in the palliative treatment of Alzheimer's disease.

AB - Pre-exposure prophylaxis (PrEP) with TDF/FTC significantly reduces the risk for HIV-1 transmission, but, to date, nobody knows if PrEP can still be useful in case of viruses harboring resistances to TDF/FTC or if alternative antiretroviral drugs might be rather proposed in selected cases. We promote the debate by describing a case of an acute infection with multiresistant HIV that occurred in a young girl who started a relationship with an HIV-infected partner who had a known multiresistant HIV. PMID- 29166778 TI - A pilot randomized controlled trial of self-help relaxation to reduce post-stroke depression. AB - OBJECTIVE: To consider the potential of self-help relaxation training to treat depression after stroke. DESIGN: Randomized controlled trial with cross-over at three months. SETTING: Community. PARTICIPANTS: In total, 21 people with stroke, aged 49-82 years. INTERVENTION: Autogenic relaxation CD. MAIN MEASURE: Hospital Anxiety and Depression Scale-Depression (HADS-D) subscale. RESULTS: No difference in depression change scores was identified between the treatment and control groups; however, on two follow-ups, significant positive differences relative to screening were found for the treatment group (at 2 months Z = -2.55, P = .011 and 12 months Z = -2.44, P = .015). A partial eta2 = .07 was identified. CONCLUSION: Self-help relaxation holds promise as a self-help treatment for depression after stroke. Findings from this trial, considered with others of relaxation for depression, suggest that a study including a total of 80 participants would likely be sufficient to establish efficacy of the treatment, relative to controls, in those with stroke. PMID- 29166779 TI - Perceived Neighborhood Environmental Factors That Maximize the Effectiveness of a Multilevel Intervention Promoting Physical Activity Among Latinas. AB - PURPOSE: This study tested whether a multilevel physical activity (PA) intervention had differential effects on PA according to participants' perceptions of their neighborhood environment. DESIGN: Two-group cluster randomized controlled trial. SETTING: San Diego, California. SUBJECTS: Analytical sample included 319 Latinas (18-65 years) from churches randomized to the following conditions: PA (n = 8 churches, n = 157 participants) or attention control (n = 8 churches, n = 162 participants). INTERVENTION: Over 12 months, PA participants were offered free PA classes (6/wk), while attention control participants were offered cancer prevention workshops. MEASURES: Baseline and 12 month follow-up measures included self-report and accelerometer-based moderate to vigorous physical activity (MVPA), sociodemographics, and perceived neighborhood environment variables. ANALYSIS: Mixed-effects models examined each PA outcome at 12-month follow-up, adjusted for church clustering, baseline PA, and sociodemographics. We tested interactions between 7 baseline perceived environment variables and study condition. RESULTS: Neighborhood esthetics was the only significant moderator of intervention effects on accelerometer-based MVPA and self-report leisure-time MVPA. Participants in the PA intervention had significantly higher PA at follow-up than attention control participants, only when participants evaluated their neighborhood esthetics favorably. CONCLUSION: Perceived neighborhood esthetics appeared to maximize the effectiveness of a multilevel PA intervention among Latinas. For sustainable PA behavior change, the environments in which Latinas are encouraged to be active may need to be evaluated prior to implementing an intervention to ensure they support active lifestyles. PMID- 29166780 TI - What Influences Parents' Fear about Children's Independent Mobility? Evidence from a State-Wide Survey of Australian Parents. AB - PURPOSE: To identify factors associated with generalized and stranger-specific parental fear (PF) about children's independent mobility (CIM), a critical aspect of physical activity. DESIGN: Cross-sectional survey; random sampling frame, minimum quotas of fathers, rural residents. SETTING: State of Victoria, Australia. SUBJECTS: Parents of children aged 9 to 15 years (n = 1779), 71% response rate. MEASURES: Validated measures of PF and fear of strangers (FoS); parent, child, social, and environmental factors. ANALYSIS: Unadjusted and adjusted linear regression stratified by child age (9-10; 11-13; 14-15). RESULTS: Adjusted models explained a substantial proportion of variance across all age groups (PF: 33.6%-36.7%; FoS: 39.1%-44.0%). Perceived disapproval from others was consistently associated with both outcomes (PF: beta =.11 to 23, p <= .05; FoS: beta =.17-.21, p <= .001) as was parents' perception of children's competence to travel safely (PF: beta = -.24 to -.11, p <= .05; FoS: beta = -.16 to -.13, p <= .01). Factors associated with FoS included having a female child (beta = -.21 to .13, p <= .001), language other than English (beta = .09 to.11, p <= .01), and low levels of parent education (beta = -.14 to -08, p <= .05). CONCLUSION: The current study suggests that social norms, child competence, and perceptions about the benefits of CIM underpin PF. This evidence informs the development of interventions to reduce PF and promote CIM and children's physical activity. PMID- 29166781 TI - Being an optimist or a pessimist and its relationship with morning cortisol release and past life review in healthy older people. AB - OBJECTIVE: Investigate the relationship between optimism and pessimism and the cortisol awakening response (CAR) and past life review in healthy older people. DESIGN: 76 older volunteers summarised their lives, highlighting the most important events, impressions and experiences. Cortisol saliva samples were collected on two consecutive weekdays. High and low optimism and pessimism groups were computed by mean split. MAIN OUTCOME MEASURES: Percentages of positive (PE) and negative events (NE) and positive (PCE) and negative cognitions and emotions (NCE) were obtained. Optimism and pessimism were measured with the Life Orientation Test Revised. The areas under the curve with respect to the ground and with respect to the increase were computed, with the latter understood as the CAR. RESULTS: The high pessimism group reported more NE and NCE and less PE and PCE (p's < 0.041). No significant differences in CAR were found between high and low optimism and pessimism groups after removing suspected non-adherent participants (p's > 0.116). Higher CAR was related to lower PCE, but higher NCE (both p < 0.008). CONCLUSION: Pessimism seems to increase the focus on negative aspects of the past, which may lead to a worse perception of life in ageing, whereas optimism contributes to a healthier CAR. PMID- 29166782 TI - Screening for the C9ORF72 repeat expansion in a greek frontotemporal dementia cohort. AB - The C9orf72 repeat expansion is a common genetic cause of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) in European populations. A previous study has reported a high frequency of the expansion in Greek ALS. However, no data have been reported on the frequency of the expansion in Greek FTD. Currently, we investigated the frequency of the C9orfF72 expansion in a well characterized cohort of 64 Greek FTD patients. We detected the C9orf72 repeat expansion in 9.3% of cases. Overall, 27.7% of familial and 2.2% of sporadic cases were expansion-positive. Five out of 6 cases had a diagnosis of behavioral variant FTD. All expansion-positive cases had fairly typical FTD presentations. Clinical features included motor neuron disease, Parkinsonism and hallucinations. We conclude that the overall frequency of C9orf72-positive cases in Greek FTD is high, comparable to Greek ALS, similar to some Western European, but significantly higher than some Mediterranean FTD populations. PMID- 29166783 TI - Improving Asthma-Related Outcomes Among Children Participating in the Head-Off Environmental Asthma in Louisiana (HEAL), Phase II Study. AB - PURPOSE: Pediatric asthma disproportionately affects low-income and minority children. The HEAL (Head-Off Environmental Asthma in Louisiana), Phase II Project was a collaborative effort with a primary focus to improve pediatric asthma management in New Orleans, Louisiana. The purpose of this article is to report clinical outcomes captured at baseline and 12-month follow-up. METHOD: HEAL (Head off Environmental Asthma in Louisiana), Phase II was a pre-post intervention study that enrolled children ages 2 to 18 years of age with a diagnosis of asthma to receive asthma education within the clinic setting. Enrollees received an asthma education intervention, an environmental evaluation, and a 12-month follow up session. Endpoints included symptom days, level of asthma control, asthma exacerbations, emergency room visits, hospitalizations, and missed school days. RESULTS: The majority of participants were aged 5 years and older, male, Black, and persistent asthmatics. Emergency room visits decreased from 41% to 20% ( p < .001). Improvements in coughing (83% to 62%, p < .001), wheezing (50% to 26%, p < .001), and chest tightness (29% to 18%, p < .001) were also seen. CONCLUSION: The novel intervention was associated with improved asthma outcomes among pediatric patients receiving care at the clinical sites in the Greater New Orleans area. PMID- 29166784 TI - Performance of the simplified acute physiology score III in acute organophosphate poisoning: A retrospective observational study. AB - The performances of acute physiology and chronic health evaluation (APACHE) II and simplified acute physiology score (SAPS) II have previously been evaluated in acute organophosphate poisoning. We aimed to compare the performance of the SAPS III with those of the APACHE II and SAPS II, as well as to identify the best tool for predicting case fatality using the standardized mortality ratios (SMRs) in acute organophosphate poisoning. A retrospective analysis of organophosphate poisoning was conducted. The APACHE II, SAPS II, and SAPS III were calculated within 24 h of admission. Discrimination was evaluated by calculating the area under the receiver operating characteristic curve (AUROC). The SMRs were calculated as 95% confidence intervals (CIs). In total, 100 cases of organophosphate poisoning were included. The in-hospital case fatality was 19%. The median scores of the APACHE II, SAPS II, and SAPS III were 20.0 (10.0-27.0), 41.0 (28.0-54.8), and 53.0 (36.3-68.8), respectively. The AUROCs were not significantly different among the APACHE II (0.815; 95% CI, 0.712-0.919), SAPS II (0.820; 95% CI, 0.719-0.912), and SAPS III (0.850; 95% CI, 0.763-0.936). Based on these scores and in-hospital case fatality, the SMRs for the APACHE II, SAPS II, and SAPS III were 1.01 (95% CI, 0.50-2.72), 1.01 (95% CI, 0.54 -2.78), and 0.98 (95% CI, 0.33-1.99), respectively. The SAPS III provided a good discrimination and satisfactory calibration in acute organophosphate poisoning. It was therefore a useful tool in predicting case fatality in acute organophosphate poisoning, similar to the APACHE II and SAPS II. PMID- 29166785 TI - Elevated Radiation Exposure Associated With Above Surface Flat Detector Mini C Arm Use. AB - BACKGROUND: This study aims to test the hypothesis that: (1) radiation exposure is increased with the intended use of Flat Surface Image Intensifier (FSII) units above the operative surface compared with the traditional below-table configuration; (2) this differential increases in a dose-dependent manner; and (3) radiation exposure varies with body part and proximity to the radiation source. METHODS: A surgeon mannequin was seated at a radiolucent hand table, positioned for volar distal radius plating. Thermoluminescent dosimeters measured exposure to the eyes, thyroid, chest, hand, and groin, for 1- and 15-minute trials from a mini C-arm FSII unit positioned above and below the operating surface. Background radiation was measured by control dosimeters placed within the operating theater. RESULTS: At 1-minute of exposure, hand and eye dosages were significantly greater with the flat detector positioned above the table. At 15-minutes of exposure, hand radiation dosage exceeded that of all other anatomic sites with the FSII in both positions. Hand exposure was increased in a dose dependent manner with the flat detector in either position, whereas groin exposure saw a dose-dependent only with the flat detector beneath the operating table. CONCLUSIONS: These findings suggest that the surgeon's hands and eyes may incur greater radiation exposure compared with other body parts, during routine mini C-arm FSII utilization in its intended position above the operating table. The clinical impact of these findings remains unclear, and future long-term radiation safety investigation is warranted. Surgeons should take precautions to protect critical body parts, particularly when using FSII technology above the operating with prolonged exposure time. PMID- 29166786 TI - Understanding concentrated insulins: a systematic review of randomized controlled trials. AB - OBJECTIVE: To compile, analyze, and summarize the literature on concentrated insulins (i.e. concentrations >100 units/mL) from randomized controlled trials and derive guidance on appropriate use of these agents. METHODS: Searches were conducted in Medline, Embase, the Cochrane Central Register of Controlled Trials, Trialtrove (through April 2016) and ClinicalTrials.gov (through April 2017) for phase 1-4 clinical studies using concentrated insulins. Selected studies included multiple-arm, randomized controlled trials evaluating subcutaneously administered concentrated insulins. Trial registration numbers (selected studies) were searched in Medline, Embase and Google Scholar (through April 2017). Late-phase studies were graded using guidance from the Agency for Healthcare Research and Quality. RESULTS: Thirty-eight completed trials (7900 participants) and 34 qualifying publications were identified. Four marketed concentrated insulins were evaluated: two long-acting basal (insulin glargine 300 units/mL and insulin degludec 200 units/mL [IDeg200]), one rapid-acting prandial (insulin lispro 200 units/mL [ILis200]), and one prandial/basal (human regular insulin 500 units/mL). Early-phase trials established bioequivalence for IDeg200 and ILis200 with the corresponding 100 units/mL formulations. Efficacy studies showed noninferior glycemic control between comparators for long-acting basal and prandial/basal products with generally low severe hypoglycemia. Six additional concentrated insulins with completed early-phase development were also identified. CONCLUSION: Concentrated-insulin products demonstrated efficacious and safe outcomes in appropriate patients. Clinical findings (HbA1c and hypoglycemia) and methodology (initiation and titration), patient factors (insulin experience and dosing requirements) and treatment characteristics (bioequivalence, potency and device features) are important considerations. This overview of these and other factors provides essential information and guidance for using concentrated insulins in clinical practice. PMID- 29166787 TI - Analysis of Expected Costs of Carpal Tunnel Syndrome Treatment Strategies. AB - BACKGROUND: Over 500 000 carpal tunnel releases costing over $2 billion are performed each year in the United States. The study's purpose is to perform a cost-minimizing analysis to identify the least costly strategy for carpal tunnel syndrome treatment utilizing existing success rates based on previously reported literature. METHODS: We evaluate the expected cost of various treatment strategies based on the likelihood of further treatments: (1) a single steroid injection followed by surgical release; (2) up to 2 steroid injections before surgical release; (3) 3 steroid injections before surgery, and (4) immediate surgical release. To reflect costs, we use our institution's billing charges to private payers and reimbursements from Medicare. A range of expected steroid injection success rates are employed based on previously published literature. RESULTS: Immediate surgical release is the costliest treatment with an expected cost of $2149 to $9927 per patient. For immediate surgical release to cost less than a single injection attempt, the probability of surgery after injection would need to exceed 80% in the Medicare reimbursement model and 87% in the institutional billing model. A single steroid injection with subsequent surgery, if needed, amounts to a direct cost savings of $359 million annually compared with immediate surgical release. Three injections before surgery, with "high" expected success rates, represent the cost-minimizing scenario. CONCLUSIONS: Although many factors must be considered when deciding upon treatment for carpal tunnel syndrome, direct payer cost is an important component, and the initial management with steroid injections minimizes these direct payer costs.

AB - BACKGROUND: Histopathological assessments approaches in bivalves have become an important tool in environmental toxicology. This study seeks to develop a quantitative histopathological index (Ih) and inflammation score as biomarkers in the aim to assess the health status of nanoparticles exposed mussels. METHODS: Digestive gland hematoxylin and eosin (H&E) stained sections from Mytilus galloprovincialis were assessed after in vivo exposure (for 3, 6 and 12 h) to silver nanoparticles (Ag-NPs < 50 nm and Ag-NPs < 100 nm) prior and after manipulating the potential uptake pathways (clathrin- and caveolae-mediated endocytosis) using amantadine and nystatin as blockers. Quantitative models evaluate the impacts of nanoparticles size, as well as their uptake routes within different time of exposure on the inflammation intensity, the digestive tubules histomorphometry and the histopathological indices. RESULTS: Silver nanoparticles clearly induced histopathological alterations in digestive gland (maximum inflammation 2.75 with AgNP < 100 nm [p < 0.05]; significant Ih with AgNP < 50 nm and AgNP < 100 nm at different time-points [p < 0.05]). Significant Ih were recorded after uptake routes were blockade: AgNP < 50 nm + nystatin and AgNP < 100 nm + amantadine; [p < 0.05] all time-points. CONCLUSIONS: Histopathological assessments showed to be promising tool in nanotoxicity which seems to depend on nanoparticles size, exposure time and interestingly to uptake routes. It was not clear: is it the length of exposure or the size of particles is more impactful. PMID- 29166789 TI - A novel approach to infertility treatment of advance-age patient with prominent intramural fibroid. AB - We report for the first time on a case of infertile advance-age patient with large intramural fibroid, who conceived following a course of Ulipristal. The patient underwent two fresh fertility preserving IVF cycles, with cryopreservation of 9 day-3 embryos, followed by a 12 weeks course of Ulipristal (5 mg per day) and a subsequent frozen-thawed embryo transfer with her own previously cryopreserved embryos. We, therefore, believe that Ulipristal is a valuable addition to treatment armamentarium of advance-age infertile patient with prominent intramural fibroid.

AB - INTRODUCTION: There are considerable interests in the development of novel small molecule CD73 inhibitors for the treatment of cancers, autoimmune diseases, precancerous syndromes, and other diseases associated with CD73 activity. Areas covered: The application claims novel substituted benzothiadiazine derivatives as CD73 inhibitors for the treatment of cancer, precancerous syndromes, AIDS, autoimmune diseases, infections, atherosclerosis, and ischemia-reperfusion injury. Many of the exemplified compounds have pIC50 values between 5 to 8.4 against CD73. Expert Opinion: These benzothiadiazine derivatives provide good leads for the discovery of potent CD73 inhibitors for the treatment of cancer and other diseases mediated by adenosine and its action on adenosine receptors. PMID- 29166792 TI - Staff views on supporting evidence based practice for children with ASD. AB - PURPOSE: A variety of empirically supported interventions are available for children with autism spectrum disorder (ASD), but previous research suggests that their selection and use within an evidence-based practice (EBP) framework in clinical settings is challenging. To date, research has primarily focused on identifying individual, organisational, and contextual barriers to EBP rather than identifying collaborative solutions to these barriers through consultation with staff. The aim of our study was to explore staff views on supporting EBP in their work with children with ASD. MATERIALS AND METHODS: We conducted five focus groups involving 29 professional (e.g., speech pathologists, teachers), paraprofessional (e.g., childcare workers), and managerial staff to explore their views. Audio recordings were transcribed verbatim and analysed using thematic analysis. RESULTS: Two central themes, comprising six categories, emerged to account for the participants' views. Initiative and Effort accounted for the range of creative strategies staff had developed to support their engagement in EBP. They also expressed the need for A Better Way involving organisational-wide support such as this engagement, including peer-to-peer mentoring. CONCLUSIONS: The findings suggest that an organisational-wide model to support engagement in EBP, with peer-to-peer mentoring at its foundation, may provide a desirable, ecologically valid, and acceptable model. Implications for Rehabilitation Clinicians and educators recognise the importance of evidence-based practice. Efforts to support evidence-based practice have focused mostly on access to research evidence. Clinicians and educators in this study were developing their own strategies based on intuition. They identified a need for organisation-wide approaches to supporting evidence-based practice. Peer-to-peer mentoring appears to be an acceptable and viable strategy. PMID- 29166793 TI - The use and discontinuation of hormone replacement therapy in women in South China. AB - OBJECTIVE: The use of hormone replacement therapy (HRT) started later in China than in European countries. The purpose of the present study was to investigate HRT patterns and reasons for the initiation and discontinuation of HRT among women in South China. METHODS: A telephone survey about menopausal status, the use of HRT, reasons for HRT discontinuation and duration of HRT treatment was conducted in 2014. RESULTS: A total of 825 telephone surveys were carried out, and 217 previous HRT users and 390 current users were recruited for this study. Among these 607 subjects, 50.7% of the women sought out HRT for hot flushes, 41.6% for fatigue and 41.5% for sleeplessness. Approximately one-third (35.9%) of the patients abandoned HRT during the following year. The reasons for stopping HRT were mainly fear of breast and uterine cancer (28.4%), reduced menopausal symptoms (22.9%) and the inconvenience of taking pills or seeing a doctor (17.9%). The factors related to HRT discontinuation were the age when HRT was initiated (odds ratio 1.59, 95% confidence interval 1.19-2.13) and education level (odds ratio 0.78, 95% confidence interval 0.62-0.98). CONCLUSIONS: The duration of HRT use in women in south China was short, and a high proportion of the women discontinued HRT. Given the high discontinuation rate and the low medical compliance, Chinese health-care providers still have much to do to let women know about the advantages and disadvantages of HRT and to encourage the use of HRT appropriately. PMID- 29166794 TI - Evaluation of liposomal behavior in the gastrointestinal tract after oral administration using real-time in vivo imaging. AB - Liposomes are regarded as promising drug carriers for enhancing the pharmacological effects of poorly absorbed drugs, such as peptides, following oral administration. Liposomal surface modifications by mucoadhesive polymers could improve drug absorption through interactions with the mucus layer. The main purpose of this study was to establish a method of monitoring the behavior of liposomes within the body after oral administration, particularly in the gastrointestinal (GI) tract, using a real-time in vivo imaging system (IVIS) to elucidate the behavior of surface-modified liposomes. Indocyanine green (ICG) was used as a near-infrared dye to label chitosan (CS) or glycol CS (GCS)-modified liposomes, and to observe the dynamic behavior of the liposomes in rats by noninvasive IVIS after oral administration. First, we validated IVIS results of the rat abdomens by comparing them to quantitative measurements of ICG fluorescence intensity in tissue homogenates. Nano-sized small unilamellar vesicles were retained longer than micro-sized multilamellar vesicles in the GI tract. Furthermore, surface-modified liposomes showed longer-term retention in the GI tract than unmodified liposomes in fasted rats. Moreover, surface modification by CS or GCS effectively prevented the excretion of liposomes from the GI tract and prolonged retention in fed rats. PMID- 29166795 TI - Pharmacological interventions for preventing acute mountain sickness: a network meta-analysis and trial sequential analysis of randomized clinical trials. AB - BACKGROUND: Individuals ascending to high altitude are at a risk of getting acute mountain sickness (AMS). The present study is a network meta-analysis comparing all the interventions available to prevent AMS. METHODS: Electronic databases were searched for randomized clinical trials evaluating the use of drugs to prevent AMS. Incidence of AMS was the primary outcome and incidence of severe AMS, paraesthesia (as side effect of acetazolamide use), headache and severe headache, and oxygen saturation were the secondary outcomes. Odds ratio [95% confidence interval] was the effect estimate for categorical outcomes and weighted mean difference for oxygen saturation. Random effects model was used to derive the direct and mixed treatment comparison pooled estimates. Trial sequential analysis and grading of the evidence for key comparisons were carried out. RESULTS: A total of 24 studies were included. Acetazolamide at 125, 250 and 375 mg twice daily, dexamethasone and ibuprofen had statistically significant lower incidence of AMS compared to placebo. All the above agents except ibuprofen were also observed to significantly reduce the incidence of severe AMS. Acetazolamide alone or in combination with Ginkgo biloba were associated with lower incidence of headache, but higher risk of paraesthesia. Acetazolamide at 125 mg and 375 mg twice daily significantly reduce the incidence of severe headache as like ibuprofen. Trial sequential analysis indicates that the current evidence is adequate for the incidence of AMS only for acetazolamide 125 and 250 mg twice daily. Similarly, the strength of evidence for acetazolamide 125 and 250 mg twice daily was moderate while it was either low or very low for all other comparisons. CONCLUSIONS: Acetazolamide at 125, 250 and 375 mg twice daily, ibuprofen and dexamethasone significantly reduce the incidence of AMS of which adequate evidence exists only for acetazolamide 125 and 250 mg twice daily therapy. Acetazolamide 125 mg twice daily could be the best in the pool considering the presence of enough evidence for preventing AMS and associated with lower incidence of paraesthesia. Key messages Acetazolamide 125, 250 and 375 mg twice daily, dexamethasone and ibuprofen reduce the incidence of AMS in high altitudes. Adequate evidence exists supporting the use of acetazolamide 125 mg and 250 mg twice daily for preventing AMS of which acetazolamide 125 mg twice daily could be the best. PMID- 29166796 TI - Structure-activity relationship investigation of benzamide and picolinamide derivatives containing dimethylamine side chain as acetylcholinesterase inhibitors. AB - A series of benzamide and picolinamide derivatives containing dimethylamine side chain (4a-4c and 7a-7i) were synthesised and evaluated for acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activity in vitro. Structure activity relationship investigation revealed that the substituted position of dimethylamine side chain markedly influenced the inhibitory activity and selectivity against AChE and BChE. In addition, it seemed that the bioactivity of picolinamide amide derivatives was stronger than that of benzamide derivatives. Among them, compound 7a revealed the most potent AChE inhibitory activity (IC50: 2.49 +/- 0.19 MUM) and the highest selectivity against AChE over BChE (Ratio: 99.40). Enzyme kinetic study indicated that compound 7a show a mixed-type inhibition against AChE. The molecular docking study revealed that this compound can bind with both the catalytic site and the peripheral site of AChE. PMID- 29166797 TI - Application of dynamic thermal imaging in a photocarcinogenesis mouse model. AB - INTRODUCTION: In clinical practice and experimental settings, cutaneous premalignant and malignant lesions are commonly diagnosed by histopathological biopsy. However, this technique is invasive and results in functional or cosmetic defects. Dynamic thermal imaging is a non-invasive technique that quantifies the infra-red (IR) radiation emitted by a subject after the introduction of external thermal stimuli (such as heat or cold). METHODS: Forty hairless albino (Crl:SKH1 hr) mice were randomised to the control group or the experimental group. The experimental group was regularly irradiated with artificial ultraviolet. Clinical photographs, immunohistochemical staining and dynamic thermal imaging results of both groups were obtained. RESULTS: As photocarcinogenesis proceeded, faster thermal recovery to basal temperature after heat stimuli was significant on dynamic thermal imaging. With histopathological correlations, it was possible to differentiate normal, premalignant and malignant cutaneous lesions according to thermal imaging results. CD 31 staining analysis showed that increased vasculature was the key change responsible for different thermal imaging results among photocarcinogenesis steps. CONCLUSIONS: Dynamic thermal imaging is useful to differentiate normal, premalignant and malignant cutaneous lesions. Increased vasculature is the key change responsible for different thermal imaging results. PMID- 29166798 TI - GRK2 as a therapeutic target for heart failure. AB - INTRODUCTION: G protein-coupled receptor (GPCR) kinase-2 (GRK2) is a regulator of GPCRs, in particular beta-adrenergic receptors (ARs), and as demonstrated by decades of investigation, it has a pivotal role in the development and progression of cardiovascular disease, like heart failure (HF). Indeed elevated levels and activity of this kinase are able to promote the dysfunction of both cardiac and adrenal alpha- and beta-ARs and to dysregulate other protective signaling pathway, such as sphingosine 1-phospate and insulin. Moreover, recent discoveries suggest that GRK2 can signal independently from GPCRs, in a 'non canonical' manner, via interaction with non-GPCR molecule or via its mitochondrial localization. Areas covered: Based on this premise, GRK2 inhibition or its genetic deletion has been tested in several disparate animal models of cardiovascular disease, showing to protect the heart from adverse remodeling and dysfunction. Expert opinion: HF is one of the leading cause of death worldwide with enormous health care costs. For this reason, the identification of new therapeutic targets like GRK2 and strategies such as its inhibition represents a new hope in the fight against HF development and progression. Herein, we will update the readers about the 'state-of-art' of GRK2 inhibition as a potent therapeutic strategy in HF. PMID- 29166799 TI - Awareness of hormone replacement therapy in medical care personnel in Jiaxing, China: a questionnaire survey. AB - This study was aimed to investigate the attitudes and knowledge of medical personnel on hormone replacement therapy (HRT) in treating perimenopausal syndrome. A total of 2580 self-administered questionnaire forms were sent to medical care professionals and the responses collected were anonymous. The questionnaire included information on levels of awareness, benefits, and potential risks of HRT. A total of 2158 questionnaire forms were filled and used for statistical analysis; 61.4% of gynecologists believed that it was necessary to conduct HRT in suitable patients, 89.1% would like to recommend the therapy to patients with perimenopausal syndrome, and 83.2% of the participants were willing to take training on HRT. The mean score of awareness of HRT among the respondents was 3.14 out of 10. The main reason for them to avoid HRT was fear of cancer (43.8%), weight gain (30.4%), addiction (21.9%), and thrombus (3.9%). These results indicated that a large proportion of gynecologists are willing to recommend HRT to a woman complaining of climacteric disorders. However, awareness of HRT among the health workers (including gynecologists) is relatively low. They are also worried about the risks. A more concerted effort should be made to better disseminate information on HRT. PMID- 29166800 TI - Comparison of all-cause costs and healthcare resource use among patients with newly-diagnosed non-valvular atrial fibrillation newly treated with oral anticoagulants. AB - OBJECTIVES: Compare costs and healthcare resource utilization (HCRU) among newly diagnosed non-valvular atrial fibrillation (NVAF) patients newly treated with dabigatran vs apixaban, rivaroxaban, or warfarin. METHODS: Newly-diagnosed adult NVAF patients initiating dabigatran, apixaban, rivaroxaban, or warfarin (index event) between October 1, 2010-December 31, 2014 were identified using MarketScan claims data, and followed until medication discontinuation, switch, inpatient death, enrollment end, or study end (December 31, 2015). Dabigatran patients were propensity-score matched 1:1 separately with apixaban, rivaroxaban, and warfarin patients. Per-patient-per-month (PPPM) all-cause cost, HCRU, and 30-day re admissions were reported. Costs were analyzed using generalized linear models. RESULTS: Final cohorts, each matched with dabigatran patients, included 8,857 apixaban patients, 26,592 rivaroxaban patients, and 33,046 warfarin patients. Dabigatran patients had lower adjusted PPPM total healthcare, inpatient, and outpatient costs compared to rivaroxaban ($4,093 vs $4,636, $1,476 vs $1,862, and $2,016 vs $2,121, respectively, all p <= .001) and warfarin ($4,199 vs $4,872, $1,505 vs $1,851, and $2,049 vs $2,514, respectively, all p < .001). Adjusted costs were similar for dabigatran and apixaban. Dabigatran patients had significantly fewer hospitalizations, outpatient visits, and pharmacy claims than rivaroxaban patients (0.06 vs 0.07, 4.84 vs 4.96 and 4.80 vs 4.93, respectively, all p < .020) and warfarin patients (0.06 vs 0.07, 4.77 vs 6.88, and 4.76 vs 5.89, respectively, all p < .001). Dabigatran patients had similar hospitalizations to apixaban, but higher outpatient visits (4.70 vs 4.31) and pharmacy claims (4.86 vs 4.61), both p < .001. CONCLUSIONS: This real-world study found adjusted all-cause costs were lower for dabigatran compared to rivaroxaban and warfarin patients and similar to apixaban patients. PMID- 29166801 TI - Endometriosis resembling endometrial cancer in a postmenopausal patient. AB - Endometriosis occurs in 2-4% of postmenopausal women. There have been a few reports of endometriosis in women in whom neither history nor diagnostic imaging indicated the presence of this disease, either at reproductive age or after menopause. A case is described of an 84-year-old patient with extensive deep pelvic endometriosis imitating advanced neoplastic process.

PMID- 29166803 TI - Oxidative stress in cerebral small vessel disease. Role of reactive species. AB - Cerebral small vessel disease (CSVD) is a wide term describing the condition affecting perforating arterial branches as well as arterioles, venules, and capillaries. Cerebral vascular net is one of the main targets of localised oxidative stress processes causing damage to vasculature, changes in the blood flow and blood-brain barrier and, in consequence, promoting neurodegenerative alterations in the brain tissue. Numerous studies report the fact of oxidation to proteins, sugars, lipids and nucleic acids, occurring in most neurodegenerative diseases mainly in the earliest stages and correlations with the development of cognitive and motor disturbances. The dysfunction of endothelium can be caused by oxidative stress and inflammatory mechanisms as a result of reactions and processes generating extensive reactive oxygen species (ROS) production such as high blood pressure, oxidised low density lipoproteins (oxLDL), very low density lipoproteins (vLDL), diabetes, homocysteinaemia, smoking, and infections. Several animal studies show positive aspects of ROS, especially within cerebral vasculature. PMID- 29166804 TI - Adolescence and risk of preterm birth in multifetal gestations. AB - OBJECTIVE: The objective of this study is to evaluate if adolescence confers additional risk for preterm delivery in multifetal gestations. METHODS: This is a retrospective review of all twin and triplet deliveries from 8/2008 to 12/2012 at two Detroit Hospitals. Outcomes in adolescent mothers aged 19 or younger (n = 59) were compared with adult controls aged 20-34 (n = 350). RESULTS: Mean gestational age at delivery in adolescents was 31.3 (SD: 5.8) weeks versus 34.2 (SD: 4.3) weeks in adults (p < .001). On multivariable analysis, adolescence was associated with preterm delivery (adjusted odds ratio [aOR], 2.3; 95% confidence intervals [95% CI], 1.1-4.7, p = .02) and early-preterm delivery (aOR, 2.2; 95% CI 1.2-4; p = .01). Adjusted rates of preterm and early-preterm delivery were markedly higher in adolescents compared with controls. Being an adolescent was also a significant risk factor for iatrogenic preterm delivery (aOR, 2.4; 95% CI 1.1-5.5; p = .04). CONCLUSIONS: Adolescents pregnant with twins or triplets deliver 3 weeks, on average, before adults and are at markedly increased risk of preterm and early preterm delivery. PMID- 29166805 TI - A case of repeated mixed mood episodes with psychotic symptoms associated with the premenstrual period in a patient with polycystic ovarian syndrome. AB - Studies have demonstrated that estrogen plays an important role in psychotic and mood disorders in women. Estrogens have a protective effect against the development of these disorders, while hypoestrogenic states may be a risk factor for the development or exacerbation of mental illness. Additionally, women with menstrual cycle abnormalities such as those with a history of anovulation may be more susceptible to monthly estrogen level fluctuation-related mood and psychotic symptoms. We present the case of a young woman with polycystic ovarian syndrome, who experienced three episodes of premenstrual mixed mood and psychotic symptoms. PMID- 29166806 TI - Regulation of stressed-induced cell death by the Bcl-2 family of apoptotic proteins. AB - Apoptosis is often deregulated in a number of human diseases. Heat-induced apoptosis is a model system for studying the consequences of protein misfolding and is mediated by the Bcl-2 family of proteins. This family consists of both pro apoptotic and anti-apoptotic members that control mitochondrial integrity. The BH3-only pro-apoptotic members are strong inducers of apoptotic cell death. Protein damaging stress can activate a process of cellular destruction known as apoptosis. The pro-apoptotic BH3-only proteins and transcription factors activate this death pathway by inhibiting the anti-apoptotic Bcl-2 family proteins eliminating cancer cells in a short period of time. PMID- 29166807 TI - Secondary Malignancies of the Bladder: Avoiding the Diagnostic Pitfall. AB - Although rare, secondary tumors of the bladder can present a diagnostic dilemma to pathologists considering a differential diagnosis of primary bladder cancer. We investigated the clinicopathologic and imaging characteristics of metastatic tumors to the bladder. We retrospectively reviewed the surgical pathology databases from 2 sites from 2013 to 2016, identifying 66 cases of secondary bladder tumors. Clinical, pathologic, and imaging findings were reviewed. Mean age at diagnosis was 63 years (range = 25-87). Females had a significantly higher proportion (44/66, 66.7%) of secondary bladder tumors compared with males (22/66, 33.3%; P = .007). In total, 56/66 (84.8%) patients had a clinical history of an in situ or invasive malignancy in another organ, and 54/66 (81.8%) patients had imaging supporting a metastatic tumor. Only 2/66 (3.0%) patients had a prior history of urothelial carcinoma. In total, 4/66 (6.1%) cases (all females) were originally misdiagnosed as primary bladder malignancies and were corrected after clinicoradiologic correlation. Overall, colorectal origin was most common (15/66, 22.7%), followed by cervical and ovarian primaries (10/66, 15.2% each). Cervical and ovarian origins predominated in the female cohort (10/44, 22.7% each), followed by endometrial (8/44, 18.2%). Colorectal and prostate primaries were the most common among males (10/22, 45.5%, and 7/22, 31.8%, respectively). Secondary bladder tumors can mimic urothelial carcinomas. In our cohort, gynecological, colorectal, and prostatic origins were most common. Clinical history, imaging, and immunohistochemical studies can be useful in avoiding this diagnostic pitfall. PMID- 29166808 TI - Mechanism of NF-kappaB signaling pathway and autophagy in the regulation of osteoblast differentiation. AB - OBJECTIVE: The objective of the present work was to investigate a possible mechanism of NF-kappaB signaling pathway and autophagy in the regulation of osteoblast differentiation, and provide experimental basis for the study of tooth eruption disorder. METHODS: Mouse osteoblast-like (MC3T3-E1) cells were inoculated with a cell density of 70%. According to the grouping experimental design, Western blot and monodansylcadaverine (MDC) detection were conducted after dosing for 24 h. The cells were divided into the following five groups: blank control group; 6.25 ug/mL SN50 group; 12.5 ug/mL SN50 group; 25 ug/mL SN50 group and 50 ug/mL SN50 group. RESULTS: Western blot analysis revealed that the expression of LC3 protein was present in the blank control group; 6.25 ug/mL SN50 group; 12.5 ug/mL SN50 group and 50 ug/mL SN50 group, with no significant differences among these groups. However, the expression of LC3 protein was significantly lower in the 25 ug/mL SN50 group. MDC detection showed that, in the blank control group; 6.25 ug/mL SN50 group; 12.5 ug/mL SN50 group and 50 ug/mL SN50 group, there was obvious green fluorescence in the cytoplasm of the osteoblasts. However, in the 25 ug/mL SN50 group, it was found that there were significantly fewer green fluorescent particles. CONCLUSION: The osteoblast itself had a strong function of autophagy. The appropriate concentration of SN50 in blocking the NF-kappaB pathway of the osteoblast was associated with the obvious inhibition of autophagy. However, the relationship between NF-kappaB signaling pathway and autophagy in the process of tooth eruption requires further study. PMID- 29166809 TI - The relationship of obesity to the timing of permanent tooth emergence in Czech children. AB - BACKGROUND: The aim of this study was to investigate the influence of BMI on the timing of permanent tooth emergence in Czech children. OBJECTIVES: In this cross sectional study, 1370 Czech children were examined. The age, gender, weight, height, all emerged permanent teeth (except third molars) of each child were all recorded. A tooth is defined as having emerged when at least any part of it has penetrated the gingiva. METHODS: A logistic regression model was used to calculate the median emergence age per tooth for both genders separately and BMI was used as a factor variable to detect statistically significant differences in the times of tooth emergence within pairs of BMI groups. The data were statistically processed using IBM SPSS Statistics 23 (SPSS Inc., Chicago, IL). RESULTS: Statistically significant differences were found for the following permanent teeth (using the FDI two-digit system): 13, 14, 15, 16, 17, 41, 44, 45, 46, 47, 33, 35, 37, 21, 24, 25, 26, 27 for girls and 12, 13, 14, 15, 16, 41, 43, 44, 45, 22, 25, 32, 34, 35, 36 for boys. These teeth were observed to emerge earlier in obese children. A similar correlation (although not statistically significant) was observed between the time of emergence of the remaining teeth and the BMI of the child. CONCLUSION: The data in this research highlight significant differences in emergence times of permanent teeth due to the influence of BMI in Czech children. These findings are important for dental treatment planning. PMID- 29166810 TI - Anesthetic management of amniotic fluid embolism -- a multi-center, retrospective, cohort study. AB - INTRODUCTION: Amniotic fluid embolism (AFE) is a rare and potentially lethal obstetric complication, commonly occurring during labor, delivery, or immediately postpartum. There is a paucity of data regarding incidence, risk factors, and clinical management. Our primary objective in this study was to evaluate clinical presentation of AFE and delineate anesthesia management of these cases. METHODS: This 10 years retrospective multi-center cohort study was performed in five tertiary university-affiliated medical centers, between the years 2005 and 2015. All documented cases of AFE identified according to the ICD guidelines were reviewed manually to determine eligibility for AFE according to Clark's criteria. All cases confirming Clark's diagnosis were included in the cohort. RESULTS: Throughout the study period, 20 cases of AFE were identified, with an incidence of 4.1 per 100,000 births. Average age at presentation was 35 +/- 5 years. Seventy percent of cases presented during vaginal delivery, 20% occurred throughout a cesarean delivery, and 10% occurred during a dilation and evacuation procedure. The most common presenting symptom was sudden loss of consciousness in 12 parturients (66.7%), fetal bradycardia in 11 parturients (55%), and shortness of breath in 10 parturients (50%). Perimortem cesarean section was performed in 55% of cases, although only one case was performed in the delivery suite, while all others were performed in the operating room. Echocardiography was performed in 60% of the cases and all were pathological. Furthermore, 20% of cases were connected to an extracorporeal membrane oxygenation machine. There was a 15% mortality rate of 15%. A further 15% suffered major neurological disability, 25% suffered minor neurological morbidity, and 45% survived without severe complications. CONCLUSION: AFE is associated with significant maternal morbidity. This study highlights the importance of providing advanced training for the delivery suite staff for cases of maternal cardiovascular collapse secondary to AFE and increasing awareness for this rare and devastating obstetric condition. PMID- 29166811 TI - Adolescent environmental enrichment prevents behavioral and physiological sequelae of adolescent chronic stress in female (but not male) rats. AB - The late adolescent period is characterized by marked neurodevelopmental and endocrine fluctuations in the transition to early adulthood. Adolescents are highly responsive to the external environment, which enhances their ability to adapt and recover from challenges when given nurturing influences, but also makes them vulnerable to aberrant development when exposed to prolonged adverse situations. Female rats are particularly sensitive to the effects of chronic stress in adolescence, which manifests as passive coping strategies and blunted hypothalamo-pituitary adrenocortical (HPA) stress responses in adulthood. We sought to intervene by exposing adolescent rats to environmental enrichment (EE) immediately prior to and during chronic stress, hypothesizing that EE would minimize or prevent the long-term effects of stress that emerge in adult females. To test this, we exposed male and female rats to EE on postnatal days (PND) 33-60 and implemented chronic variable stress (CVS) on PND 40-60. CVS consisted of twice-daily unpredictable stressors. Experimental groups included: CVS/unenriched, unstressed/EE, CVS/EE and unstressed/unenriched (n = 10 of each sex/group). In adulthood, we measured behavior in the open field test and forced swim test (FST) and collected blood samples following the FST. We found that environmental enrichment given during the adolescent period prevented the chronic stress-induced transition to passive coping in the FST and reversed decreases in peak adrenocortical responsiveness observed in adult females. Adolescent enrichment had little to no effect on males or unstressed females tested in adulthood, indicating that beneficial effects are specific to females that were exposed to chronic stress.

AB - The objective of this study was to assess trends in health insurance coverage, health service utilization, and health care access among working-age adults with and without disabilities before and after full implementation of the Affordable Care Act (ACA), and to identify current disability-based disparities following full implementation of the ACA. The ACA was expected to have a disproportionate impact on working-age adults with disabilities, because of their high health care usage as well as their previously limited insurance options. However, most published research on this population does not systematically look at effects before and after full implementation of the ACA. As the US Congress considers new health policy reforms, current and accurate data on this vulnerable population are essential. Weighted estimates, trend analyses and analytic models were conducted using the 1998-2016 National Health Interview Surveys (NHIS) and the 2014 Medical Expenditure Panel Survey. Compared with working-age adults without disabilities, those with disabilities are less likely to work, more likely to earn below the federal poverty level, and more likely to use public insurance. Average health costs for this population are 3 to 7 times higher, and access problems are far more common. Repeal of key features of the ACA, like Medicaid expansion and marketplace subsidies, would likely diminish health care access for working-age adults with disabilities.

AB - Brain glioma is one of the most common and devastating intracranial malignancies with a high mortality. Chemotherapy for brain glioma is not ideal due to blood brain barrier (BBB) and multidrug resistance (MDR). The objectives of the present study were to develop a kind of RGD (Arg-Gly-Asp) tripeptide modified vinorelbine plus tetrandrine liposomes to achieve BBB transportation, MDR reversion and glioma cell targeting simultaneously. The studies were performed on glioma cells, resistant glioma cells and glioma-bearing mice. Results showed that the constructed liposomes with suitable physicochemical properties could significantly enhance the transport across BBB, obviously accumulate in glioma cells, and exhibit evident capabilities in diminishing brain glioma in mice. Action mechanism studies indicated that the enhanced anticancer efficacy could be attribute to the follows: prolonged elimination half-life (7.093 +/- 1.311 h); increased AUC0-24 h (28.92 +/- 2.66 mg/L*h); transporting across BBB; enhanced cellular uptake; down-regulation on P-gp (0.49 +/- 0.06 fold); inducing apoptosis via activating caspase 8, 9, and 3 (2.40 +/- 0.22, 3.57 +/- 0.29, and 4.33 +/- 0.30 folds, respectively). In conclusion, the RGD modified vinorelbine plus tetrandrine liposomes may offer a promising therapeutic strategy for treatment of brain glioma. PMID- 29166815 TI - Disposition of [14C]hydroquinone in Harlan Sprague-Dawley rats and B6C3F1/N mice: species and route comparison. AB - 1. Hydroquinone (HQ) is present in some foods and has varied industrial, medical and consumer uses. These studies were undertaken to investigate the disposition of HQ in rats and mice following gavage, intravenous (IV) and dermal exposure. 2. [14 C]HQ administered (0.5, 5 or 50 mg/kg) by gavage or IV routes to male and female Harlan Sprague-Dawley (HSD) rats and B6C3F1/N mice was well absorbed and rapidly excreted primarily in urine. Radioactivity remaining in tissues at 72 h was <1% for both species at all dose levels and routes. No sex, species or route related differences in disposition were found. 3. With dermal application of 2, 10 or 20% [14 C]HQ, mice absorbed higher percentages of the dose than rats (37, 12, 12% versus 18.6, 4.43 and 1.79%, respectively). The HQ mass absorbed by mice increased with dose, while in rats it was more constant over the dose range. Absorbed HQ was rapidly excreted in urine of both species and urinary excretion indicated continued absorption over the exposure period. No sex differences in disposition were found. 4. The oral bioavailability of HQ at 5 mg/kg was low in both rats (1.6%) and mice (3.9%) demonstrating significant first pass metabolism. Dermal bioavailability in mice was 9.4% following application of 2% formulation. 5. Urinary metabolites for both species and all routes included the glucuronide and sulfate conjugates; no parent was found in urine. PMID- 29166817 TI - Ambiguities in the taxonomic assignment and species delineation of botryllid ascidians from the Israeli Mediterranean and other coastlines. AB - Based on mtCOI sequences comparisons, recent studies reassigned the 'dwarf Botrylloides leachii' from the Levant as Botrylloides nigrum. Here we conducted a survey of the literature and of deposited mtCOI sequences of botryllid ascidians, elucidating ambiguities in their taxonomy. We found that the species, dwarf morph of Botrylloides leachii, Botrylloides nigrum, Botryllus aster and Botryllus arenaceus are grouped together on a single molecular taxon. Then, results of three additional markers (18S, 28S, H3) contradicted literature suggestions, revealing minute distances between Botrylloides leachii and the 'dwarf Botrylloides leachii'. Moreover, only Botrylloides leachii and the 'dwarf Botrylloides leachii' develop giant ampullae as an allorecognition response. Our results raise the possibility that inadequate identification, together with faults in molecular assignment, including queries regarding the efficacy of the mtCOI as the exclusive barcoding tool in botryllid ascidians, is the major culprits responsible for the emerged inconsistencies between the mtCOI sequences and traditional taxonomy. Thus, we assign the Levantine dwarf form as Botrylloides aff. leachii. PMID- 29166816 TI - Tobacco exposure-related alterations in DNA methylation and gene expression in human monocytes: the Multi-Ethnic Study of Atherosclerosis (MESA). AB - Alterations in DNA methylation and gene expression in blood leukocytes are potential biomarkers of harm and mediators of the deleterious effects of tobacco exposure. However, methodological issues, including the use of self-reported smoking status and mixed cell types have made previously identified alterations in DNA methylation and gene expression difficult to interpret. In this study, we examined associations of tobacco exposure with DNA methylation and gene expression, utilizing a biomarker of tobacco exposure (urine cotinine) and CD14+ purified monocyte samples from 934 participants of the community-based Multi Ethnic Study of Atherosclerosis (MESA). Urine cotinine levels were measured using an immunoassay. DNA methylation and gene expression were measured with microarrays. Multivariate linear regression was used to test for associations adjusting for age, sex, race/ethnicity, education, and study site. Urine cotinine levels were associated with methylation of 176 CpGs [false discovery rate (FDR)<0.01]. Four CpGs not previously identified by studies of non-purified blood samples nominally replicated (P value<0.05) with plasma cotinine-associated methylation in 128 independent monocyte samples. Urine cotinine levels associated with expression of 12 genes (FDR<0.01), including increased expression of P2RY6 (Beta +/- standard error = 0.078 +/- 0.008, P = 1.99 * 10-22), a gene previously identified to be involved in the release of pro-inflammatory cytokines. No cotinine-associated (FDR<0.01) methylation profiles significantly (FDR<0.01) correlated with cotinine-associated (FDR<0.01) gene expression profiles. In conclusion, our findings i) identify potential monocyte-specific smoking associated methylation patterns and ii) suggest that alterations in methylation may not be a main mechanism regulating gene expression in monocytes in response to cigarette smoking. PMID- 29166818 TI - Can Digital Technology Enhance Social Connectedness Among Older Adults? A Feasibility Study. AB - This study examined the feasibility of a novel communication technology to enhance social connectedness among older adults in residential care. Research suggests that technology can create opportunities for social connectedness, helping alleviate social isolation and loneliness. Studies on implementation and feasibility of such technological interventions, particularly among frail and institutionalized older adults, are scant. Data were gathered in a 3-month deployment with 12 older adults, including semistructured interviews with participants and relatives/friends, psychometric scales, field observations, and usability tests. Data were analyzed with qualitative profiling, thematic analysis, and Friedman tests. The technology was a feasible communication tool, although requiring an adaptation period. Use increased perceived social interaction with ties, but increased social connectedness (meaningful social interaction) was only reported by participants with geographically distant relatives. Sense of well-being and confidence with technology was enhanced, but negative effects were also observed. Findings are useful for researchers and practitioners interested in technological interventions. PMID- 29166819 TI - Pregnancy outcomes among women with asthma. AB - PURPOSE: The purpose of this study is to examine the association between maternal asthma and pregnancy, delivery and neonatal outcomes. MATERIALS AND METHODS: We carried out a retrospective cohort study using the Health Care Cost and Utilization Project-Nationwide Inpatient Sample (HCUP-NIS) database from 2003 to 2011. Among women who delivered during this time period, we compared pregnancy, delivery, and neonatal outcomes in asthmatics versus non-asthmatics. Multivariate logistic regression was used to estimate adjusted odds ratios and 95% confidence intervals. RESULTS: In a cohort of 7,772,999 pregnant women, 223,236 (2.9%) had asthma. The prevalence of asthma-complicated pregnancies rose over the study period from 1.9% in 2003 to 3.7% in 2011 (p < .001). Pregnant asthmatics had more pre-existing health conditions, such as diabetes, chronic hypertension, obesity, and thyroid disease, and were more likely to smoke. Even after adjustment for these comorbidities, and other covariates, within statistical models, asthma was found to be associated with greater risk of several pregnancy complications: gestational hypertension, preeclampsia, gestational diabetes, placenta previa, preterm premature rupture of membranes, placental abruption, chorioamnionitis, preterm delivery, postpartum hemorrhage, venous thromboembolism, caesarean section delivery, and maternal mortality. Neonates born to asthmatics had greater risk of being small for gestational age and for having congenital anomalies, and lower risk of intrauterine fetal death. CONCLUSIONS: Asthma is associated with an increase in adverse pregnancy, labor, and neonatal outcomes. Close surveillance of asthmatic patients during the prenatal period is warranted and care in a tertiary hospital is advised. PMID- 29166820 TI - Sinonasal SMARCB1 (INI1) Deficient Carcinoma With Yolk Sac Tumor Differentiation: Report of a Case and Comparison With INI1 Expression in Gonadal Germ Cell Tumors. AB - SMARCB1 (INI1) deficient sinonasal carcinoma is a recently recognized entity with wide histomorphologic spectrum. We present a case of this carcinoma that contained, in addition to a "common" morphology, scattered foci of yolk sac tumor differentiation. The tumor occurred in paranasal sinuses in a 44-year-old woman. Immunohistochemically, it was diffusely negative for INI1, whereas an expression of yolk sac tumor markers (alpha-fetoprotein, glypican-3, CDX2) was limited to the yolk sac tumor component. For comparison with the present case, we performed INI1 immunostaining on a series of 11 gonadal germ cell tumors with yolk sac tumor differentiation. All of these cases showed strong and diffuse expression of INI1, in contrast with the present sinonasal tumor. Our findings expand the morphologic spectrum of SMARCB1 (INI1) deficient sinonasal carcinoma. In addition, we show preliminarily that gonadal germ cell tumors with yolk sac tumor differentiation are not SMARCB1/INI1-deficient. PMID- 29166821 TI - The ribosomal DNA metaphase loop of Saccharomyces cerevisiae gets condensed upon heat stress in a Cdc14-independent TORC1-dependent manner. AB - Chromosome morphology in Saccharomyces cerevisiae is only visible at the microscopic level in the ribosomal DNA array (rDNA). The rDNA has been thus used as a model to characterize condensation and segregation of sister chromatids in mitosis. It has been established that the metaphase structure ("loop") depends, among others, on the condensin complex; whereas its segregation also depends on that complex, the Polo-like kinase Cdc5 and the cell cycle master phosphatase Cdc14. In addition, Cdc14 also drives rDNA hypercondensation in telophase. Remarkably, since all these components are essential for cell survival, their role on rDNA condensation and segregation was established by temperature sensitive (ts) alleles. Here, we show that the heat stress (HS) used to inactivate ts alleles (25 oC to 37 oC shift) causes rDNA loop condensation in metaphase-arrested wild type cells, a result that can also be mimicked by other stresses that inhibit the TORC1 pathway. Because this condensation might challenge previous findings with ts alleles, we have repeated classical experiments of rDNA condensation and segregation, yet using instead auxin-driven degradation alleles (aid alleles). We have undertaken the protein degradation at lower temperatures (25 oC) and concluded that the classical roles for condensin, Cdc5, Cdc14 and Cdc15 still prevailed. Thus, condensin degradation disrupts rDNA higher organization, Cdc14 and Cdc5 degradation precludes rDNA segregation and Cdc15 degradation still allows rDNA hypercompaction in telophase. Finally, we provide direct genetic evidence that this HS-mediated rDNA condensation is dependent on TORC1 but, unlike the one observed in anaphase, is independent of Cdc14. PMID- 29166822 TI - Myeloid cell leukemia 1 (MCL-1), an unexpected modulator of protein kinase signaling during invasion. AB - Myeloid cell leukemia-1 (MCL-1), closely related to B-cell lymphoma 2 (BCL-2), has a well-established role in cell survival and has emerged as an important target for cancer therapeutics. We have demonstrated that inhibiting MCL-1 is efficacious in suppressing tumour progression in pre-clinical models of breast cancer and revealed that in addition to its role in cell survival, MCL-1 modulated cellular invasion. Utilizing a MCL-1-specific genetic antagonist, we found two possible mechanisms; firstly MCL-1 directly binds to and alters the phosphorylation of the cytoskeletal remodeling protein, Cofilin, a protein important for cytoskeletal remodeling during invasion, and secondly MCL-1 modulates the levels SRC family kinases (SFKs) and their targets. These data provide evidence that MCL-1 activities are not limited to endpoints of extracellular and intracellular signaling culminating in cell survival as previously thought, but can directly modulate the output of SRC family kinases signaling during cellular invasion. Here we review the pleotropic roles of MCL-1 and discuss the implications of this newly discovered effect on protein kinase signaling for the development of cancer therapeutics. PMID- 29166823 TI - Foot-and-mouth disease virus capsid protein VP2 activates the cellular EIF2S1 ATF4 pathway and induces autophagy via HSPB1. AB - Foot-and-mouth disease virus (FMDV) can result in economical destruction of cloven-hoofed animals. FMDV infection has been reported to induce macroautophagy/autophagy; however, the precise molecular mechanisms of autophagy induction and effect of FMDV capsid protein on autophagy remain unknown. In the present study, we report that FMDV infection induced a complete autophagy process in the natural host cells of FMDV, and inhibition of autophagy significantly decreased FMDV production, suggesting that FMDV-induced autophagy facilitates viral replication. We found that the EIF2S1-ATF4 pathway was activated and the AKT-MTOR signaling pathway was inhibited by FMDV infection. We also observed that ultraviolet (UV)-inactivated FMDV can induce autophagy. Importantly, our work provides the first piece of evidence that expression of FMDV capsid protein VP2 can induce autophagy through the EIF2S1-ATF4-AKT-MTOR cascade, and we found that VP2 interacted with HSPB1 (heat shock protein family B [small] member 1) and activated the EIF2S1-ATF4 pathway, resulting in autophagy and enhanced FMDV replication. In addition, we show that VP2 induced autophagy in a variety of mammalian cell lines and decreased aggregates of a model mutant HTT (huntingtin) polyglutamine expansion protein (HTT103Q). Overall, our results demonstrate that FMDV capsid protein VP2 induces autophagy through interaction with HSPB1 and activation of the EIF2S1-ATF4 pathway. PMID- 29166824 TI - Increased visceral adiposity index associated with sexual dysfunction in men. AB - OBJECTIVE: Visceral adipose index (VAI) is a novel parameter for the evaluation of visceral obesity. As we know that obesity is a risk factor for erectile dysfunction (ED). So, in this study, we compared the VAI levels between the men with ED and without ED. MATERIALS AND METHOD: A total of 177 men were included in the study. Ninety-five men with ED and 82 men without ED (control). All men were evaluated for ED by Index of Erectile Function-5 items (IIEF-5). VAI levels were calculated using body mass index, high density lipoprotein and tryglyceride levels. RESULTS: Mean age was 53.5 (38-69) in men who have ED and 53.1 (34-69) in control. The men with ED had higher body mass index (BMI), triglyceride (TG) levels, higher waist circumference (WC) and lower high-density lipoprotein cholesterol (HDL-C) levels. Mean VAI level was 5.18 +/- 2.50 in study group and 3.47 +/- 1.76 in control goup, respectively. VAI levels were statistically higher in men with ED (p < .001). DISCUSSION: The simplicity of WC and BMI measurement and TG and HDL assessment, make VAI an easily applicable index for the evaluation of visceral fat dysfunction. VAI can be useful index for the evaluation and calculation of erectile dysfunction risk. PMID- 29166825 TI - Lifetime Consequences of Early-Life and Midlife Access to Health Insurance: A Review. AB - Over the past decade, the number of studies examining the effects of health insurance has grown rapidly, along with the breadth of outcomes considered. In light of growing research in this area and the intense policy focus on coverage expansions in the United States, there is need for an up-to-date and comprehensive literature review and synthesis of lessons learned. We reviewed 112 experimental or quasi-experimental studies on the effects of health insurance prior to people becoming eligible for Medicare on a broad set of outcomes. Over the past decade, evidence related to the effect of increased access to health insurance has strengthened, illuminating that children and vulnerable adults are most likely to see health and economic benefits. We identified promising areas for future study in this active and burgeoning research area, noting benefit design of health insurance and outcomes such as government program participation and self-reported health status as targets. PMID- 29166826 TI - Polychlorinated biphenyls (PCBs) in River Niger, Nigeria: Occurrence, distribution and composition profiles. AB - Contamination of rivers with persistent organic pollutants (POPs) is an issue of current global concern. Polychlorinated biphenyls (PCBs) are POPs with origin from commercial, incineration and industrial sources. Hence, there is a need for monitoring their occurrence and distribution in the environment. This study assessed the occurrence, distribution and composition profiles of PCBs in River Niger, Nigeria. Surface and bottom water samples were collected in consecutive quarters for a period of 2 years, covering the beginning and end of the rainy seasons and the dry seasons, from five locations (Gurara, Lokoja, Onitsha, Brass and Nicolas) along River Niger. A total of 240 water samples were collected using a Van Dorn water sampler. EPA method 3510c was used with slight modifications for sample preparation and analysis. The PCBs were analysed using a Hewlett Packard GC 5890 Series 11 with electron capture detection, and confirmation was made using a Shimadzu GCMS QP2010. The higher molecular weight marker PCBs (?CB 138, 153 and 180) were more dominant than the lighter homologues (?CB 28, 52 and 101), while commercial sources Co-PCBs (80.8 +/- 61.7 to 288.3 +/- 102.0 ng L-1) were more dominant than the incineration sources (34.9 +/- 3.82 to 75.5 +/- 65.2 ng L 1). The POPs load in River Niger water varied in both time and space. In surface water of the River Niger, ?PCBs were higher during the rainy season, as a result of storm run-off from land-based sources. In the Brass and Nicolas Rivers during the dry season, the ?PCBs were higher during low tide. There was no noticeable pattern during the rainy season. It may be concluded from this study that the water of River Niger is not good for human consumption or abstraction of water from the river for drinking water treatment. PMID- 29166827 TI - Exposure to 835 MHz radiofrequency electromagnetic field induces autophagy in hippocampus but not in brain stem of mice. AB - The exploding popularity of mobile phones and their close proximity to the brain when in use has raised public concern regarding possible adverse effects from exposure to radiofrequency electromagnetic fields (RF-EMF) on the central nervous system. Numerous studies have suggested that RF-EMF emitted by mobile phones can influence neuronal functions in the brain. Currently, there is still very limited information on what biological mechanisms influence neuronal cells of the brain. In the present study, we explored whether autophagy is triggered in the hippocampus or brain stem after RF-EMF exposure. C57BL/6 mice were exposed to 835 MHz RF-EMF with specific absorption rates (SAR) of 4.0 W/kg for 12 weeks; afterward, the hippocampus and brain stem of mice were dissected and analyzed. Quantitative real-time polymerase chain reaction (qRT-PCR) analysis demonstrated that several autophagic genes, which play key roles in autophagy regulation, were significantly upregulated only in the hippocampus and not in the brain stem. Expression levels of LC3B-II protein and p62, crucial autophagic regulatory proteins, were significantly changed only in the hippocampus. In parallel, transmission electron microscopy (TEM) revealed an increase in the number of autophagosomes and autolysosomes in the hippocampal neurons of RF-EMF-exposed mice. The present study revealed that autophagy was induced in the hippocampus, not in the brain stem, in 835 MHz RF-EMF with an SAR of 4.0 W/kg for 12 weeks. These results could suggest that among the various adaptation processes to the RF EMF exposure environment, autophagic degradation is one possible mechanism in specific brain regions. PMID- 29166828 TI - Nurses' systems thinking competency, medical error reporting, and the occurrence of adverse events: a cross-sectional study. AB - BACKGROUND: Healthcare professionals' systems thinking is emphasized for patient safety. AIMS: To report nurses' systems thinking competency, and its relationship with medical error reporting and the occurrence of adverse events. DESIGN: A cross-sectional survey using a previously validated Systems Thinking Scale (STS), was conducted. METHODS: Nurses from two teaching hospitals were invited to participate in the survey. There were 407 (60.3%) completed surveys. RESULTS: The mean STS score was 54.5 (SD 7.3) out of 80. Nurses with higher STS scores were more likely to report medical errors (odds ratio (OR) = 1.05; 95% confidence interval (CI) = 1.02-1.08) and were less likely to be involved in the occurrence of adverse events (OR = 0.96; 95% CI = 0.93-0.98). CONCLUSIONS: Nurses showed moderate systems thinking competency. Systems thinking was a significant factor associated with patient safety. Impact Statement: The findings of this study highlight the importance of enhancing nurses' systems thinking capacity to promote patient safety. PMID- 29166829 TI - Rucaparib: A Poly(ADP-Ribose) Polymerase Inhibitor for BRCA-Mutated Relapsed Ovarian Cancer. AB - OBJECTIVE: To review the pharmacology, safety, efficacy, and the role of rucaparib in the treatment of relapsed, advanced ovarian cancer. SUMMARY: A total of 2 phase I/II trials and 1 phase II trial have evaluated the safety and efficacy of oral rucaparib in ovarian cancer. In patients with deleterious BRCA1/2 mutation, an overall response rate of 80% was achieved in the phase II trial Assessment of Rucaparib in Ovarian CancEr Trial 2 (ARIEL2). In the same trial, progression-free survival was higher in patients with BRCA1/2 mutation and BRCA wild types with high loss of heterozygosity (LOH) than BRCA wild types with low LOH. Rucaparib was found to be relatively well tolerated in clinical trials, with the most common adverse events being anemia, fatigue, and nausea. CONCLUSION: Rucaparib appears to be a safe and effective new option in the treatment of relapsed, advanced BRCA1/2 mutant ovarian cancer. The role of rucaparib in this setting will likely expand and be further elucidated as results from several ongoing studies become available. PMID- 29166830 TI - The Role of Cefepime in the Treatment of Extended-Spectrum Beta-Lactamase Infections. AB - OBJECTIVE: To review the efficacy of cefepime for use in infections caused by extended-spectrum beta-lactamase (ESBL)-producing organisms. DATA SOURCES: A PubMed literature search (May 2000 to June 2017) was performed using the keyword cefepime and the MeSH terms beta-lactamases, cephalosporinases, and Enterobacteriaceae infections. STUDY SELECTION AND DATA EXTRACTION: All human, English language studies evaluating cefepime use for the treatment of ESBL producing Escherichia coli and Klebsiella pneumoniae infections were included. DATA SYNTHESIS: Studies assessing the use of cefepime for ESBL infections are few, and clinical studies are limited by design and sample size. The largest pharmacokinetic/pharmacodynamic study, a Monte Carlo simulation using data from the U.S. SENTRY antimicrobial surveillance program, evaluating cefepime use for infections due to ESBL-producing organisms found a 95% to 100% probability of target attainment with traditional cefepime dosing regimens. Most clinical studies found that patients treated with cefepime empirically and definitively had higher rates of mortality than those treated with carbapenems. However, in concordance with other studies reporting minimum inhibitory concentration (MIC) data, lower MICs were associated with lower mortality. CONCLUSIONS: Cefepime should be avoided for empiric treatment of suspected ESBL infections and should only be considered for definitive treatment if the MIC <=1 ug/mL. However, the site and severity of infection, local resistance patterns, and patient-specific risk factors should also help guide antimicrobial selection. PMID- 29166831 TI - Removal of organic matter and ammoniacal nitrogen from landfill leachate using the UV/H2O2 photochemical process. AB - This study investigates the effects of pH, H2O2 concentration and reaction time of the UV/H2O2 photochemical process on the removal of organic matter and ammonia from biologically pre-treated landfill leachates in anaerobic stabilization ponds. The results show that the concentration of H2O2 and the initial pH are significant factors, with no significant interaction between them. A pH of 3 is the optimum value for the UV/H2O2 process for the removal of organic matter, resulting in 51.63% chemical oxygen demand (COD) removal in addition to the removal of aromatic compounds. The N-NH3 removal showed little variation between pH values of 1, 5, 7, 11 and 13; the removal was on the order of 16.43 +/- 2.00%. The consumption of H2O2 was elevated at pH 9, 11 and 13; at these pH values, the average removal was 94.56 +/- 0.43%, compared to 43.07% at pH 3. First-order polynomial models and reaction times on the order of 15 min are sufficient for optimization studies and for evaluation of the effects of the studied parameters. The results of this study support the optimization of the UV/H2O2 process for the removal of organic matter and ammonia from landfill leachates. PMID- 29166832 TI - Conditioning exercises in ski jumping: biomechanical relationship of squat jumps, imitation jumps, and hill jumps. AB - As hill jumps are very time-consuming, ski jumping athletes often perform various imitation jumps during training. The performed jumps should be similar to hill jumps, but a direct comparison of the kinetic and kinematic parameters has not been performed yet. Therefore, this study aimed to correlate 11 common parameters during hill jumps (Oberstdorf Germany), squat jumps (wearing indoor shoes), and various imitation jumps (rolling 4 degrees , rolling flat, static; jumping equipment or indoor shoes) on a custom-built instrumented vehicle with a catch by the coach. During the performed jumps, force and video data of the take-off of 10 athletes were measured. The imitation and squat jumps were then ranked. The main difference between the hill jumps and the imitation and squat jumps is the higher maximal force loading rate during the hill jumps. Imitation jumps performed on a rolling platform, on flat ground were the most similar to hill jumps in terms of the force-time, and leg joint kinematic properties. Thus, non-hill jumps with a technical focus should be performed from a rolling platform with a flat inrun with normal indoor shoes or jumping equipment, and high normal force loading rates should be the main focus of imitation training. PMID- 29166833 TI - Backward bifurcation and oscillations in a nested immuno-eco-epidemiological model. AB - This paper introduces a novel partial differential equation immuno-eco epidemiological model of competition in which one species is affected by a disease while another can compete with it directly and by lowering the first species' immune response to the infection, a mode of competition termed stress induced competition. When the disease is chronic, and the within-host dynamics are rapid, we reduce the partial differential equation model (PDE) to a three dimensional ordinary differential equation (ODE) model. The ODE model exhibits backward bifurcation and sustained oscillations caused by the stress-induced competition. Furthermore, the ODE model, although not a special case of the PDE model, is useful for detecting backward bifurcation and oscillations in the PDE model. Backward bifurcation related to stress-induced competition allows the second species to persist for values of its invasion number below one. Furthermore, stress-induced competition leads to destabilization of the coexistence equilibrium and sustained oscillations in the PDE model. We suggest that complex systems such as this one may be studied by appropriately designed simple ODE models. PMID- 29166834 TI - The entomopathogenic fungus Metarhizium robertsii communicates with the insect host Galleria mellonella during infection. AB - Parasitic fungi are the only pathogens that can infect insect hosts directly through their proteinaceous exoskeleton. Penetration of the cuticle requires the release of fungal enzymes, including proteinases, which act as virulence factors. Insects can sense fungal infections and activate innate immune responses, including the synthesis of antifungal peptides and proteinase inhibitors that neutralize the incoming proteinases. This well-studied host response is epigenetically regulated by histone acetylation/deacetylation. Here we show that entomopathogenic fungi can in turn sense the presence of insect-derived antifungal peptides and proteinase inhibitors, and respond by inducing the synthesis of chymotrypsin-like proteinases and metalloproteinases that degrade the host-derived defense molecules. The rapidity of this response is dependent on the virulence of the fungal strain. We confirmed the specificity of the pathogen response to host-derived defense molecules by LC/MS and RT-PCR analysis, and correlated this process with the epigenetic regulation of histone acetylation/deacetylation. This cascade of responses reveals that the coevolution of pathogens and hosts can involve a complex series of attacks and counterattacks based on communication between the invading fungal pathogen and its insect host. The resolution of this process determines whether or not pathogenesis is successful. PMID- 29166835 TI - Activation of STAT3-mediated CXCL12 up-regulation in the dorsal root ganglion contributes to oxaliplatin-induced chronic pain. AB - Oxaliplatin-induced chronic painful neuropathy is the most common dose-limiting adverse event that negatively affects cancer patients' quality of life. However, the underlying molecular mechanisms are still unclear. In the present study, we found that the intraperitoneal administration of oxaliplatin at 4 mg/kg for five consecutive days noticeably upregulated the expression of CXC motif ligand 12 (CXCL12) in the dorsal root ganglion, and the intrathecal injection of an anti CXCL12 neutralizing antibody or CXCL12 siRNA attenuated the mechanical allodynia and thermal hyperalgesia induced by oxaliplatin. We also found that the signal transducers and transcription activator 3 (STAT3) was activated in the dorsal root ganglion, and inhibition of STAT3 with S3I-201 or the injection of AAV-Cre GFP into STAT3flox/flox mice prevented the upregulation of CXCL12 expression in the dorsal root ganglion and chronic pain following oxaliplatin administration. Double-label fluorescent immunohistochemistry findings also showed that p-STAT3 was mainly localized in CXCL12-positive cells in the dorsal root ganglion. Furthermore, the results of a chromatin immunoprecipitation assay revealed that p STAT3 might be essential for oxaliplatin-induced CXCL12 upregulation via binding directly to the specific position of the CXCL12 gene promoter. Finally, we found that cytokine TNF-alpha and IL-1beta increases mediated the STAT3 activation following oxaliplatin treatment. Taken together, these findings suggested that the upregulation of CXCL12 via TNF-alpha/IL-1beta-dependent STAT3 activation contributes to oxaliplatin-induced chronic pain.

AB - Background The Nav1.7 subtype of voltage-gated sodium channels is specifically expressed in sensory and sympathetic ganglia neurons where it plays an important role in the generation and transmission of information related to pain sensation. Human loss or gain-of-function mutations in the gene encoding Nav1.7 channels (SCN9A) are associated with either absence of pain, as reported for congenital insensitivity to pain, or with exacerbation of pain, as reported for primary erythromelalgia and paroxysmal extreme pain disorder. Based on this important human genetic evidence, numerous drug discovery efforts are ongoing in search for Nav1.7 blockers as a novel therapeutic strategy to treat pain conditions. Results We are reporting here a novel approach to study Nav1.7 function in cultured rat sensory neurons. We used live cell imaging combined with electrical field stimulation to evoke and record action potential-driven calcium transients in the neurons. We have shown that the tarantula venom peptide Protoxin-II, a known Nav1.7 subtype selective blocker, inhibited electrical field stimulation-evoked calcium responses in dorsal root ganglia neurons with an IC50 of 72 nM, while it had no activity in embryonic hippocampal neurons. The results obtained in the live cell imaging assay were supported by patch-clamp studies as well as by quantitative PCR and Western blotting experiments that confirmed the presence of Nav1.7 mRNA and protein in dorsal root ganglia but not in embryonic hippocampal neurons. Conclusions The findings presented here point to a selective effect of Protoxin-II in sensory neurons and helped to validate a new method for investigating and comparing Nav1.7 pharmacology in sensory versus central nervous system neurons. This will help in the characterisation of the selectivity of novel Nav1.7 modulators using native ion channels and will provide the basis for the development of higher throughput models for enabling pain-relevant phenotypic screening. PMID- 29166837 TI - Cisplatin alters the function and expression of N-type voltage-gated calcium channels in the absence of morphological damage of sensory neurons. AB - Platinum-based chemotherapeutic agents, such as cisplatin, are still frequently used for treating various types of cancer. Besides its high effectiveness, cisplatin has several serious side effects. One of the most common side effects is dorsal root ganglion (DRG) neurotoxicity. However, the mechanisms underlying this neurotoxicity are still unclear and controversially discussed. Cisplatin mediated modulation of voltage-gated calcium channels (VGCCs) in the DRG neurons has been shown to alter intracellular calcium homeostasis, a process critical for the induction of neurotoxicity. Using the whole-cell patch-clamp technique, immunostaining, behavioural experiments and electron microscopy (EM) of rat DRGs, we here demonstrate that cisplatin-induced neurotoxicity is due to functional alteration of VGCC, but not due to morphological damage. In vitro application of cisplatin (0.5 uM) increased N-type VGCC currents ( ICa(V)) in small DRG neurons. Repetitive in vivo administration of cisplatin (1.5 mg/kg, cumulative 12 mg/kg) increased the protein level of N-type VGCC over 26 days, with the protein level being increased for at least 14 days after the final cisplatin administration. Behavioural studies revealed that N-type VGCCs are crucial for inducing symptoms of cisplatin-related neuropathic pain, such as thermal and mechanical hyperalgesia. EM and histology showed no evidence of any structural damage, apoptosis or necrosis in DRG cells after cisplatin exposure for 26 days. Furthermore, no nuclear DNA damage in sensory neurons was observed. Here, we provide evidence for a mainly functionally driven induction of neuropathic pain by cisplatin. PMID- 29166838 TI - Immunohistochemical localization of nerve growth factor, tropomyosin receptor kinase A, and p75 in the bone and articular cartilage of the mouse femur. AB - Sequestration of nerve growth factor (NGF) significantly attenuates skeletal pain in both animals and humans. However, relatively little is known about the specific cell types that express NGF or its cognate receptors tropomyosin receptor kinase A (TrkA) and p75 in the intact bone and articular cartilage. In the present study, antibodies raised against NGF, TrkA, and p75 (also known as CD271) were used to explore the expression of these antigens in the non decalcified young mouse femur. In general, all three antigens displayed a remarkably restricted expression in bone and cartilage with less than 2% of all DAPI+ cells in the femur displaying expression of any one of the three antigens. Robust NGF immunoreactivity was found in mostly CD-31- blood vessel-associated cells, a small subset of CD-31+ endothelial cells, an unidentified group of cells located at the subchondral bone/articular cartilage interface, and a few isolated, single cells in the bone marrow. In contrast, p75 and TrkA were almost exclusively expressed by nerve fibers located nearby NGF+ blood vessels. The only non-neuronal expression of either p75 or TrkA in the femur was the expression of p75 by a subset of cells located in the deep and middle zone of the articular cartilage. Understanding the factors that tightly regulate the basal level of expression in normal bone and how the expression of NGF, TrkA, and p75 change in injury, disease, and aging may provide insights into novel therapies that can reduce skeletal pain and improve skeletal health. PMID- 29166840 TI - Ethics in nursing: A systematic review of the framework of evidence perspective. AB - AIM: To determine the current state of knowledge on nursing and ethics and to assess the knowledge and experience based on the evidence in this regard. BACKGROUND: Although ethics is at the center of the nursing profession and the ethical issues affecting nurses are given much importance, few studies have focused on professional ethics in nursing. In this respect, ethics has become a concept that contains controversial and ambiguous situations. DESIGN: The Preferred Reporting Items for Systematic Reviews and Meta-analyses guide, a basic search algorithm, was taken. DATA SOURCES: Cochrane, PubMed, CINAHL Complete, PsycINFO, and ULAKBIM from 2012 to 2016. REVIEW METHODS: Following a systematic search strategy, all papers were assessed in relation to inclusion criteria and type of study. When sufficient information was not available in the title and summary of the works, the necessary data were evaluated in full texts. RESULTS: This review was completed with 27 articles meeting the research criteria. The evaluation identified six themes: (1) ethics and nursing, (2) ethical difficulties/ethical dilemmas and nursing, (3) ethical competence and nursing, (4) professional ethics and nursing, (5) ethics, education, and nursing, and (6) ethics in health research. CONCLUSION: As a result of the review, a synthesis of high evidence-level research relating to nursing ethics was obtained. The emphasis was on the importance of further research and education so that the ethical aspects of nursing can be better understood throughout the studies. Nursing researchers' level of evidence on ethics and their orientation to high research design will shed light on uncertain and controversial aspects of the subject. Ethical consideration: Since this was a systematic review, no ethical approval was required. There is no conflict of interest in this literature review. PMID- 29166839 TI - The synergistic effect of treatment with triptolide and MK-801 in the rat neuropathic pain model. AB - Triptolide (T10), an active component of Tripterygium wilfordii Hook F, is reported to have potent anti-inflammatory and analgesic effects. Additionally, MK 801, a noncompetitive N-methyl-D-aspartate receptor antagonist, can reduce glutamate toxicity and has a significant analgesic effect on chronic pain. In this study, we tested the possible synergistic analgesic ability by intrathecal administration of T10 and MK-801 for the treatment of neuropathic pain. Single T10 (3, 10, or 30 ug/kg), MK-801 (10, 30, or 90 ug/kg), or a combination of them were intrathecally administrated in rats with spinal nerve ligation. We found that single administration of T10 caused a slow-acting but long-term analgesic effect, while single administration of MK-801 caused a fast-acting but short-term effect. Administration of their combination showed obviously synergic analgesia and the 1:3 ratio of T10 to MK-801 reached the peak effect. Furthermore, application of T10 and/or MK-801 significantly inhibited the activation of microglia and astrocyte and phosphorylation of STAT3 and NR2B in the spinal dorsal horn induced by chronic neuropathic pain. Our data suggest that the combination of T10 and MK-801 may be a potentially novel strategy for treatment of neuropathic pain. PMID- 29166841 TI - Noninvasive optical and nuclear imaging of Staphylococcus-specific infection with a human monoclonal antibody-based probe. AB - Staphylococcus aureus infections are a major threat in healthcare, requiring adequate early-stage diagnosis and treatment. This calls for novel diagnostic tools that allow noninvasive in vivo detection of staphylococci. Here we performed a preclinical study to investigate a novel fully-human monoclonal antibody 1D9 that specifically targets the immunodominant staphylococcal antigen A (IsaA). We show that 1D9 binds invariantly to S. aureus cells and may further target other staphylococcal species. Importantly, using a human post-mortem implant model and an in vivo murine skin infection model, preclinical feasibility was demonstrated for 1D9 labeled with the near-infrared fluorophore IRDye800CW to be applied for direct optical imaging of in vivo S. aureus infections. Additionally, 89Zirconium-labeled 1D9 could be used for positron emission tomography imaging of an in vivo S. aureus thigh infection model. Our findings pave the way towards clinical implementation of targeted imaging of staphylococcal infections using the human monoclonal antibody 1D9. PMID- 29166842 TI - Measurement error correction in the least absolute shrinkage and selection operator model when validation data are available. AB - Measurement of serum biomarkers by multiplex assays may be more variable as compared to single biomarker assays. Measurement error in these data may bias parameter estimates in regression analysis, which could mask true associations of serum biomarkers with an outcome. The Least Absolute Shrinkage and Selection Operator (LASSO) can be used for variable selection in these high-dimensional data. Furthermore, when the distribution of measurement error is assumed to be known or estimated with replication data, a simple measurement error correction method can be applied to the LASSO method. However, in practice the distribution of the measurement error is unknown and is expensive to estimate through replication both in monetary cost and need for greater amount of sample which is often limited in quantity. We adapt an existing bias correction approach by estimating the measurement error using validation data in which a subset of serum biomarkers are re-measured on a random subset of the study sample. We evaluate this method using simulated data and data from the Tucson Epidemiological Study of Airway Obstructive Disease (TESAOD). We show that the bias in parameter estimation is reduced and variable selection is improved. PMID- 29166843 TI - Stagnant contraceptive sales after the Zika epidemic in Brazil. AB - OBJECTIVES: Our aim was to assess national hormonal and non-hormonal contraceptive sales in Brazil after the Zika virus outbreak. METHODS: Pharmaceutical companies based in Brazil provided data on monthly sales from September 2016 to June 2017. Data from both the public and private sectors were obtained about sales of registered, available modern contraceptive methods: combined oral contraceptive pill; progestin-only pill; vaginal and transdermal contraceptives; injectable contraceptives; long-acting reversible contraceptive (LARC) methods, including the copper-releasing intrauterine device, the levonorgestrel-releasing intrauterine system and the etonogestrel-releasing subdermal implant; and emergency contraceptive pills. RESULTS: Seventy-eight percent of sales comprised pills, patches and vaginal rings (11.1-13.8 million cycles/units per month), followed by emergency contraceptive pills (1.8-2.6 million pills), injectables (1.2-1.4 million ampoules) and LARC methods (6500 17,000 devices). CONCLUSIONS: The data showed much higher sales of short-acting methods compared with more effective LARC methods. The public sector needs to strengthen its focus on ensuring better access to LARC methods through a systematic approach ensuring regular supply, improved professional skills and better demand generation to couples wishing to avoid or delay pregnancy. In Zika virus-affected areas, many women of reproductive age may want to delay or postpone pregnancy by using an effective LARC method. The public sector should review its policies on LARC, as the need for these methods especially in Zika virus endemic areas may increase. A clear emphasis on quality in services, access and use is warranted. PMID- 29166844 TI - The phase model of psychotherapy outcome: Domain-specific trajectories of change in outpatient treatment. AB - OBJECTIVE: The Phase model of psychotherapy outcome assumes a log-linear trajectory of change and allows predictions about the three outcome domains of Well-being, Symptoms, and Interpersonal functioning. Although the model has been partly validated, little is known about the types of trajectories in the specific domains and about the transferability of the model to treatments of longer duration. This study tested whether the domain-specific change trajectories followed a log-linear curve as postulated by the Phase model. Furthermore, it was examined whether the speed of change differed between the domains. METHOD: Growth curves were modeled using hierarchical linear modeling on an outpatient sample (N = 351), with treatment duration averaging 52 sessions. RESULTS: A log-linear curve best explained the change trajectories of the domains Well-being and Symptoms as well as the Global score of psychopathology, whereas Interpersonal functioning tends to improve in a linear pattern. Estimated slopes were biggest for Well-being and smallest for Interpersonal functioning. CONCLUSIONS: In the present study, the predictions of the Phase model concerning multidimensional phases were validated. The finding that trajectories of change are not uniformly log-linear, but either log-linear or linear in a domain-specific manner, is partly inconsistent with the model. PMID- 29166845 TI - Identifying the minimum number of microsatellite loci needed to assess population genetic structure: A case study in fly culturing. AB - Small, isolated populations are constantly threatened by loss of genetic diversity due to drift. Such situations are found, for instance, in laboratory culturing. In guarding against diversity loss, monitoring of potential changes in population structure is paramount; this monitoring is most often achieved using microsatellite markers, which can be costly in terms of time and money when many loci are scored in large numbers of individuals. Here, we present a case study reducing the number of microsatellites to the minimum necessary to correctly detect the population structure of two Drosophila nigrosparsa populations. The number of loci was gradually reduced from 11 to 1, using the Allelic Richness (AR) and Private Allelic Richness (PAR) as criteria for locus removal. The effect of each reduction step was evaluated by the number of genetic clusters detectable from the data and by the allocation of individuals to the clusters; in the latter, excluding ambiguous individuals was tested to reduce the rate of incorrect assignments. We demonstrate that more than 95% of the individuals can still be correctly assigned when using eight loci and that the major population structure is still visible when using two highly polymorphic loci. The differences between sorting the loci by AR and PAR were negligible. The method presented here will most efficiently reduce genotyping costs when small sets of loci ("core sets") for long-time use in large-scale population screenings are compiled. PMID- 29166846 TI - Recurrent cerebral infarction in anterior and posterior circulation territories associated with persistent primitive hypoglossal artery and carotid artery dissection: a case report. AB - The persistent primitive hypoglossal artery (PPHA) is the second most common persistent carotid-vertebrobasilar anastomosis. We present a rare case of an 82 year-old woman who diagnosed as acute cerebral infarction three times in both the anterior and posterior circulation territories with a right-sided PPHA and ipsilateral carotid artery dissection (CAD). Microembolus monitoring results suggested that microembolic caused by CAD associated with PPHA should be recognized as a possible cause of multiple infarctions in both the anterior and posterior circulation territories. For these patients, appropriate treatment measures should be taken for prevention of stroke recurrence.

PMID- 29166850 TI - Fishes in the desert: mitochondrial variation and phylogeography of Danakilia (Actinopterygii: Cichlidae) and Aphanius (Actinopterygii: Cyprinodontidae) in the Danakil Depression of northeastern Africa. AB - The Danakil Depression in northeastern Africa represents one of the harshest arid environments on Earth, yet two genera of fishes, Danakilia (Cichlidae) and Aphanius (Cyprinodontidae), share its sparse aquatic habitats. The evolutionary history of these fishes is investigated here in the context of genetic, geological and paleoenvironmental information. We collected samples from seven sites and assessed phylogeographic relationships using concatenated COI and cytb mtDNA genes. Danakilia morphospecies show low differentiation at mitochondrial markers, but variation is partitioned between a northern cluster containing D. dinicolai plus three undescribed riverine populations, and a southern cluster including two creek populations of D. franchettii separated by the hypersaline waters of Lake Afrera. Aphanius displayed four genetically distinct clades (A. stiassnyae in Lake Afrera; one distributed across the entire area; one in Lake Abaeded; and one in the Shukoray River), but without clear large-scale geographic structure. However, Danakil Aphanius are clearly differentiated from A. dispar sensu stricto from the Sinai Peninsula. Geological evidence suggests that after the Late Pleistocene closure of the Danakil-Red Sea connection, increased post glacial groundwater availability caused the formation of a brackish paleo-lake flooding the entire region below the -50 m contour. Fish populations previously isolated in coastal oases during glaciation were able to mix in the paleo-lake. Subsequently, in a more arid phase starting ~7300 BP, paleo-lake regression isolated fishes in separate drainages, triggering their still ongoing diversification. PMID- 29166851 TI - Novel mathematical model to estimate ball impact force in soccer. AB - To assess ball impact force during soccer kicking is important to quantify from both performance and chronic injury prevention perspectives. We aimed to verify the appropriateness of previous models used to estimate ball impact force and to propose an improved model to better capture the time history of ball impact force. A soccer ball was fired directly onto a force platform (10 kHz) at five realistic kicking ball velocities and ball behaviour was captured by a high-speed camera (5,000 Hz). The time history of ball impact force was estimated using three existing models and two new models. A new mathematical model that took into account a rapid change in ball surface area and heterogeneous ball deformation showed a distinctive advantage to estimate the peak forces and its occurrence times and to reproduce time history of ball impact forces more precisely, thereby reinforcing the possible mechanics of 'footballer's ankle'. Ball impact time was also systematically shortened when ball velocity increases in contrast to practical understanding for producing faster ball velocity, however, the aspect of ball contact time must be considered carefully from practical point of view. PMID- 29166852 TI - Unsupervised gene selection using biological knowledge : application in sample clustering. AB - BACKGROUND: Classification of biological samples of gene expression data is a basic building block in solving several problems in the field of bioinformatics like cancer and other disease diagnosis and making a proper treatment plan. One big challenge in sample classification is handling large dimensional and redundant gene expression data. To reduce the complexity of handling this high dimensional data, gene/feature selection plays a major role. RESULTS: The current paper explores the use of biological knowledge acquired from Gene Ontology database in selecting the proper subset of genes which can further participate in clustering of samples. The proposed feature selection technique is unsupervised in nature as it does not utilize any class label information in the process of gene selection. At the end, a multi-objective clustering approach is deployed to cluster the available set of samples in the reduced gene space. CONCLUSIONS: Reported results show that consideration of biological knowledge in gene selection technique not only reduces the feature space dimensionality in great extent but also improves the accuracy of sample classification. The obtained reduced gene space is validated using strong biological significance tests. In order to prove the supremacy of our proposed gene selection based sample clustering technique, a thorough comparative analysis has also been performed with state-of-the-art techniques. PMID- 29166853 TI - Proteomic insight into fruit set of cucumber (Cucumis sativus L.) suggests the cues of hormone-independent parthenocarpy. AB - BACKGROUND: Parthenocarpy is an excellent agronomic trait that enables crops to set fruit in the absence of pollination and fertilization, and therefore to produce seedless fruit. Although parthenocarpy is widely recognized as a hormone dependent process, hormone-insensitive parthenocarpy can also be observed in cucumber; however, its mechanism is poorly understood. To improve the global understanding of parthenocarpy and address the hormone-insensitive parthenocarpy shown in cucumber, we conducted a physiological and proteomic analysis of differently developed fruits. RESULTS: Physiological analysis indicated that the natural hormone-insensitive parthenocarpy of 'EC1' has broad hormone-inhibitor resistance, and the endogenous hormones in the natural parthenocarpy (NP) fruits were stable and relatively lower than those of the non-parthenocarpic cultivar '8419 s-1.' Based on the iTRAQ technique, 683 fruit developmental proteins were identified from NP, cytokinin-induced parthenocarpic (CP), pollinated and unpollinated fruits. Gene Ontology (GO) analysis showed that proteins detected from both set and aborted fruits were involved in similar biological processes, such as cell growth, the cell cycle, cell death and communication. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed that 'protein synthesis' was the major biological process that differed between fruit set and fruit abortion. Clustering analysis revealed that different protein expression patterns were involved in CP and NP fruits. Forty-one parthenocarpy-specialized DEPs (differentially expressed proteins) were screened and divided into two distinctive groups: NP-specialized proteins and CP-specialized proteins. Furthermore, qRT-PCR and western blot analysis indicated that NP-specialized proteins showed hormone- or hormone-inhibitor insensitive expression patterns in both ovaries and seedlings. CONCLUSIONS: In this study, the global molecular regulation of fruit development in cucumber was revealed at the protein level. Physiological and proteomic comparisons indicated the presence of hormone independent parthenocarpy and suppression of fruit abortion in cucumber. The proteomic analysis suggested that hormone-independent parthenocarpy is regulated by hormone-insensitive proteins such as the NP-specialized proteins. Moreover, the regulation of fruit abortion suppression may be closely related to protein synthesis pathways. PMID- 29166854 TI - A single dose of dezocine suppresses emergence agitation in preschool children anesthetized with sevoflurane-remifentanil. AB - BACKGROUND: Emergence agitation (EA) is a common phenomenon in preschool children during emergence from general anesthesia. This study evaluated the safety and efficacy of dezocine for emergence agitation in preschool children anesthetized with sevoflurane-remifentanil. METHODS: A total of 100 preschool children, scheduled for elective laparoscopic repair of an inguinal hernia by high ligation of the hernia sac under sevoflurane-remifentanil anesthesia were randomized into two groups: Group C (n = 50) received Ringer's lactate 10 mL and Group D received Ringer's lactate 10 mL containing dezocine 0.1 mg/kg, postoperatively. RESULTS: Incidence of EA, defined as a score >= 3 on Aono's four point scale or Pediatric Anesthesia Emergence Delirium (PAED) score >= 10 in the PACU (10% vs. 76%) and the percentage of patients with severe EA (PAED score >= 13) (12% vs. 76%) were significantly lower in Group D compared to Group C (P < 0.05). Mean Children and Infants Postoperative Pain Scale (CHIPPS) score was significantly lower in Group D compared to Group C (1.2 +/- 0.5 vs. 5.2 +/- 0.6; P < 0.05). Patients need for fentanyl (18% vs. 4%) or propofol rescue (20% vs. 0) was significantly greater in Group C compared to Group D. No significant differences in other relative aspects after surgery between groups. CONCLUSION: Administration of dezocine 0.1 mg/kg decreased the incidence and severity of EA in preschool children that had undergone laparoscopic repair of an inguinal hernia by high ligation of the hernia sac under sevoflurane-remifentanil anesthesia.

PMID- 29166855 TI - Identification of differentially expressed genes in flower, leaf and bulb scale of Lilium oriental hybrid 'Sorbonne' and putative control network for scent genes. AB - BACKGROUND: Lily is an economically important plant, with leaves and bulbs consisting of overlapping scales, large ornamental flowers and a very large genome. Although it is recognized that flowers and bulb scales are modified leaves, very little is known about the genetic control and biochemical differentiation underlying lily organogenesis and development. Here we examined the differentially expressed genes in flower, leaf and scale of lily, using RNA sequencing, and identified organ-specific genes, including transcription factors, genes involved in photosynthesis in leaves, carbohydrate metabolism in bulb scales and scent and color production in flowers. RESULTS: Over 11Gb data were obtained and 2685, 2296, and 1709 differentially expressed genes were identified in the three organs, with 581, 662 and 977 unique DEGs in F-vs-S, L-vs-S and L-vs F comparisons. By functional enrichment analysis, genes likely to be involved in biosynthetic pathways leading to floral scent production, such as 1-deoxy-D xylulose-5-phosphate synthase (DXS), 3-ketoacyl-CoA thiolase (KAT), hydroperoxide lyase (HPL), geranylgeranyl pyrophosphate (GGPP) 4-hydroxy-3-methylbut-2-en-1-yl diphosphate (HDS) and terpene synthase (TPS), and floral color genes, such as dihydroflavonol 4-reductase (DFR), chalcone synthase (CHS), chalcone isomerase (CHI), flavonol synthase (FLS) were identified. Distinct groups of genes that participate in starch and sucrose metabolism, such as sucrose synthase (SS), invertase (INV), sucrose phosphate synthase (SPS), starch synthase (SSS), starch branching enzyme (SBE), ADP-glucose pyrophosphorylase (AGP) andbeta-amylase (BAM) and photosynthesis genes (Psa, Psb, Pet and ATP) were also identified. The expression of six floral fragrance-related DGEs showed agreement between qRT-PCR results and RPKM values, confirming the value of the data obtained by RNA-seq. We obtained the open reading frame of the terpene synthase gene from Lilium 'Sorbonne', designated LsTPS, which had 99.55% homology to transcript CL4520.Contig5_All. In addition, 54, 48 and 50 differently expressed transcription factor were identified by pairwise comparisons between the three organs and a regulatory network for monoterpene biosynthesis was constructed. CONCLUSIONS: Analysis of differentially expressed genes in flower, leaf and bulb scale of lily, using second generation sequencing technology, yielded detailed information on lily metabolic differentiation in three organs. Analysis of the expression of flower scent biosynthesis genes has provided a model for the regulation of the pathway and identified a candidate gene encoding an enzyme catalyzing the final step in scent production. These digital gene expression profiles provide a valuable and informative database for the further identification and analysis of structural genes and transcription factors in different lily organs and elucidation of their function. PMID- 29166856 TI - Glycyl-alanyl-histidine protects PC12 cells against hydrogen peroxide toxicity. AB - BACKGROUND: Peptides with cytoprotective functions, including antioxidants and anti-infectives, could be useful therapeutics. Carnosine, beta-alanine-histidine, is a dipeptide with anti-oxidant properties. Tripeptides of Ala-His-Lys, Pro-His His, or Tyr-His-Tyr are also of interest in this respect. RESULTS: We synthesized several histidine-containing peptides including glycine or alanine, and tested their cytoprotective effects on hydrogen peroxide toxicity for PC12 cells. Of all these peptides (Gly-His-His, Ala-His-His, Ala-His-Ala, Ala-Ala-His, Ala-Gly-His, Gly-Ala-His (GAH), Ala-His-Gly, His-Ala-Gly, His-His-His, Gly-His-Ala, and Gly Gly-His), GAH was found to have the strongest cytoprotective activity. GAH decreased lactate dehydrogenase (LDH) leakage, apoptosis, morphological changes, and nuclear membrane permeability changes against hydrogen peroxide toxicity in PC12 cells. The cytoprotective activity of GAH was superior to that of carnosine against hydrogen peroxide toxicity in PC12 cells. GAH also protected PC12 cells against damage caused by actinomycin D and staurosporine. Additionally, it was found that GAH also protected SH-SY5Y and Jurkat cells from damage caused by hydrogen peroxide, as assessed by LDH leakage. CONCLUSION: Thus, a novel tripeptide, GAH, has been identified as having broad cytoprotective effects against hydrogen peroxide-induced cell damage. PMID- 29166857 TI - Genome analysis of the foxtail millet pathogen Sclerospora graminicola reveals the complex effector repertoire of graminicolous downy mildews. AB - BACKGROUND: Downy mildew, caused by the oomycete pathogen Sclerospora graminicola, is an economically important disease of Gramineae crops including foxtail millet (Setaria italica). Plants infected with S. graminicola are generally stunted and often undergo a transformation of flower organs into leaves (phyllody or witches' broom), resulting in serious yield loss. To establish the molecular basis of downy mildew disease in foxtail millet, we carried out whole genome sequencing and an RNA-seq analysis of S. graminicola. RESULTS: Sequence reads were generated from S. graminicola using an Illumina sequencing platform and assembled de novo into a draft genome sequence comprising approximately 360 Mbp. Of this sequence, 73% comprised repetitive elements, and a total of 16,736 genes were predicted from the RNA-seq data. The predicted genes included those encoding effector-like proteins with high sequence similarity to those previously identified in other oomycete pathogens. Genes encoding jacalin-like lectin-domain containing secreted proteins were enriched in S. graminicola compared to other oomycetes. Of a total of 1220 genes encoding putative secreted proteins, 91 significantly changed their expression levels during the infection of plant tissues compared to the sporangia and zoospore stages of the S. graminicola lifecycle. CONCLUSIONS: We established the draft genome sequence of a downy mildew pathogen that infects Gramineae plants. Based on this sequence and our transcriptome analysis, we generated a catalog of in planta-induced candidate effector genes, providing a solid foundation from which to identify the effectors causing phyllody. PMID- 29166858 TI - ADAGE signature analysis: differential expression analysis with data-defined gene sets. AB - BACKGROUND: Gene set enrichment analysis and overrepresentation analyses are commonly used methods to determine the biological processes affected by a differential expression experiment. This approach requires biologically relevant gene sets, which are currently curated manually, limiting their availability and accuracy in many organisms without extensively curated resources. New feature learning approaches can now be paired with existing data collections to directly extract functional gene sets from big data. RESULTS: Here we introduce a method to identify perturbed processes. In contrast with methods that use curated gene sets, this approach uses signatures extracted from public expression data. We first extract expression signatures from public data using ADAGE, a neural network-based feature extraction approach. We next identify signatures that are differentially active under a given treatment. Our results demonstrate that these signatures represent biological processes that are perturbed by the experiment. Because these signatures are directly learned from data without supervision, they can identify uncurated or novel biological processes. We implemented ADAGE signature analysis for the bacterial pathogen Pseudomonas aeruginosa. For the convenience of different user groups, we implemented both an R package (ADAGEpath) and a web server ( http://adage.greenelab.com ) to run these analyses. Both are open-source to allow easy expansion to other organisms or signature generation methods. We applied ADAGE signature analysis to an example dataset in which wild-type and ?anr mutant cells were grown as biofilms on the Cystic Fibrosis genotype bronchial epithelial cells. We mapped active signatures in the dataset to KEGG pathways and compared with pathways identified using GSEA. The two approaches generally return consistent results; however, ADAGE signature analysis also identified a signature that revealed the molecularly supported link between the MexT regulon and Anr. CONCLUSIONS: We designed ADAGE signature analysis to perform gene set analysis using data-defined functional gene signatures. This approach addresses an important gap for biologists studying non traditional model organisms and those without extensive curated resources available. We built both an R package and web server to provide ADAGE signature analysis to the community. PMID- 29166859 TI - Divergent clades or cryptic species? Mito-nuclear discordance in a Daphnia species complex. AB - BACKGROUND: Genetically divergent cryptic species are frequently detected by molecular methods. These discoveries are often a byproduct of molecular barcoding studies in which fragments of a selected marker are used for species identification. Highly divergent mitochondrial lineages and putative cryptic species are even detected in intensively studied animal taxa, such as the crustacean genus Daphnia. Recently, eleven such lineages, exhibiting genetic distances comparable to levels observed among well-defined species, were recorded in the D. longispina species complex, a group that contains several key taxa of freshwater ecosystems. We tested if three of those lineages represent indeed distinct species, by analyzing patterns of variation of ten nuclear microsatellite markers in six populations. RESULTS: We observed a discordant pattern between mitochondrial and nuclear DNA, as all individuals carrying one of the divergent mitochondrial lineages grouped at the nuclear level with widespread, well-recognized species coexisting at the same localities (Daphnia galeata, D. longispina, and D. cucullata). CONCLUSIONS: A likely explanation for this pattern is the introgression of the mitochondrial genome of undescribed taxa into the common species, either in the distant past or after long-distance dispersal. The occurrence of highly divergent but rare mtDNA lineages in the gene pool of widespread species would suggest that hybridization and introgression in the D. longispina species complex is frequent even across large phylogenetic distances, and that discoveries of such distinct clades must be interpreted with caution. However, maintenance of ancient polymorphisms through selection is another plausible alternative that may cause the observed discordance and cannot be entirely excluded. PMID- 29166860 TI - msaABCR operon is involved in persister cell formation in Staphylococcus aureus. AB - BACKGROUND: Persister cells comprise a phenotypic variant that shows extreme antibiotic tolerance resulting in treatment failures of bacterial infections. While this phenomenon has posed a great threat in public health, mechanisms underlying their formation in Staphylococcus aureus remain largely unknown. Increasing evidences of the presence of persister cells in recalcitrant infections underscores the great urgency to unravel the mechanism by which these cells develop. Previously, we characterized msaABCR operon that plays roles in regulation of virulence, biofilm development and antibiotic resistance. We also characterized the function of MsaB protein and showed that MsaB is a putative transcription factor that binds target DNA in response to nutrients availability. RESULTS: In this study, we compared the number of persister cell in wild type, msaABCR deletion mutant and the complemented strain in two backgrounds USA300 LAC and Mu50. Herein, we report that msaABCR deletion mutant forms significantly less number of persister cells relative to wild type after challenge with various antibiotics in planktonic and biofilm growth conditions. Complementation of the msaABCR operon restored wild type phenotype. Combined antibiotic therapy along with msaABCR deletion significantly improves the killing kinetics of stationary phase and biofilm S. aureus cells. Transcriptomics analysis showed that msaABCR regulates several metabolic genes, transcription factors, transporters and enzymes that may play role in persister cells formation, which we seek to define in the future. CONCLUSIONS: This study presented a new regulator, msaABCR operon, that is involved in the persister cells formation, which is a poorly understood in S. aureus. Indeed, we showed that msaABCR deletion significantly reduces the persister cells formation in all growth phases tested. Although, we have not yet defined the mechanism, we have shown that msaABCR regulates several metabolic, transporters, and extracellular proteases genes that have been previously linked with persister cells formation in other bacterial systems. Taken together, this study showed that inactivation of the msaABCR operon enhances the effectiveness of antibiotics for the treatment of S. aureus infections, especially in context of persister cells. PMID- 29166861 TI - Comprehensive transcriptome analysis reveals distinct regulatory programs during vernalization and floral bud development of orchardgrass (Dactylis glomerata L.). AB - BACKGROUND: Vernalization and the transition from vegetative to reproductive growth involve multiple pathways, vital for controlling floral organ formation and flowering time. However, little transcription information is available about the mechanisms behind environmental adaption and growth regulation. Here, we used high-throughput sequencing to analyze the comprehensive transcriptome of Dactylis glomerata L. during six different growth periods. RESULTS: During vernalization, 4689 differentially expressed genes (DEGs) significantly increased in abundance, while 3841 decreased. Furthermore, 12,967 DEGs were identified during booting stage and flowering stage, including 7750 up-regulated and 5219 down-regulated DEGs. Pathway analysis indicated that transcripts related to circadian rhythm, photoperiod, photosynthesis, flavonoid biosynthesis, starch, and sucrose metabolism changed significantly at different stages. Coexpression and weighted correlation network analysis (WGCNA) analysis linked different stages to transcriptional changes and provided evidence of inner relation modules associated with signal transduction, stress responses, cell division, and hormonal transport. CONCLUSIONS: We found enrichment in transcription factors (TFs) related to WRKY, NAC, AP2/EREBP, AUX/IAA, MADS-BOX, ABI3/VP1, bHLH, and the CCAAT family during vernalization and floral bud development. TFs expression patterns revealed intricate temporal variations, suggesting relatively separate regulatory programs of TF modules. Further study will unlock insights into the ability of the circadian rhythm and photoperiod to regulate vernalization and flowering time in perennial grass. PMID- 29166862 TI - Gastric stump carcinoma as a long-term complication of pancreaticoduodenectomy: report of two cases and review of the English literature. AB - BACKGROUND: Gastric stump carcinoma is an exceptional and poorly known long-term complication after pancreaticoduodenectomy. CASES PRESENTATION: Two patients developed gastric stump carcinoma 19 and 10 years after pancreaticoduodenectomy for malignant ampulloma and total pancreaticoduodenectomy for pancreatic adenocarcinoma, respectively. Both patients had pT4 signet-ring cell carcinoma involving the gastrojejunostomy site that was revealed by bleeding or obstruction. Patient 1 is alive and remains disease-free 36 months after completion gastrectomy. Patient 2 presented with peritoneal carcinomatosis and died after palliative surgery. We identified only 3 others cases in the English literature. CONCLUSIONS: Prolonged biliary reflux might be the most important risk factor of gastric stump carcinoma following pancreaticoduodenectomy. Its incidence might increase in the future due to prolonged survival observed after pancreaticoduodenectomy for benign and premalignant lesions. PMID- 29166863 TI - Characterization of the inner membrane protein BB0173 from Borrelia burgdorferi. AB - BACKGROUND: The bacterial spirochete Borrelia burgdorferi is the causative agent of the most commonly reported arthropod-borne illness in the United States, Lyme disease. A family of proteins containing von Willebrand Factor A (VWFA) domains adjacent to a MoxR AAA+ ATPase have been found to be highly conserved in the genus Borrelia. Previously, a VWFA domain containing protein of B. burgdorferi, BB0172, was determined to be an outer membrane protein capable of binding integrin alpha3beta1. In this study, the characterization of a new VWFA domain containing membrane protein, BB0173, is evaluated in order to define the location and topology of this multi-spanning membrane protein. In addition, functional predictions are made. RESULTS: Our results show that BB0173, in contrast to BB0172, is an inner membrane protein, in which the VWFA domain is exposed to the periplasmic space. Further, BB0173 was predicted to have an aerotolerance regulator domain, and expression of BB0173 and the surrounding genes was evaluated under aerobic and microaerophilic conditions, revealing that these genes are downregulated under aerobic conditions. Since the VWFA domain containing proteins of B. burgdorferi are highly conserved, they are likely required for survival of the pathogen through sensing diverse environmental oxygen conditions. CONCLUSIONS: Presently, the complex mechanisms that B. burgdorferi uses to detect and respond to environmental changes are not completely understood. However, studying the mechanisms that allow B. burgdorferi to survive in the highly disparate environments of the tick vector and mammalian host could allow for the development of novel methods of preventing acquisition, survival, or transmission of the spirochete. In this regard, a putative membrane protein, BB0173, was characterized. BB0173 was found to be highly conserved across pathogenic Borrelia, and additionally contains several truly transmembrane domains, and a Bacteroides aerotolerance-like domain. The presence of these functional domains and the highly conserved nature of this protein, strongly suggests a required function of BB0173 in the survival of B. burgdorferi. PMID- 29166864 TI - Prevalence and risk factors for depression and anxiety in Chinese patients with Parkinson disease. AB - BACKGROUND: Anxiety and depression are common in Parkinson disease and both are important determinants of quality of life in patients. Several risk factors are identified but few research have investigated general and Parkinson's disease (PD)-specific factors comprehensively. The aim of this work was to explore PD specific and -non-specific risk factors for PD with depression or anxiety. METHODS: A cross-sectional survey was performed in 403 patients with PD. Multivariate logistic analysis was used to investigate the prevalence and risk factors for the depression and anxiety in PD. The data of patients included demographic information, medicine history, disease duration, age at onset (AAO), family history, anti-parkinsonism drug, modified Hoehn and Yahr staging (H-Y) stage, scales of motor and non-motor symptoms and substantia nigra (SN) echogenic areas. RESULTS: 403 PD patients were recruited in the study. Depression and anxiety were present in 11.17% and 25.81% respectively. Marital status, tumor, higher Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) II score, dyskinesia, higher Hamilton Anxiety Rating Scale (HARS) score and lower the Parkinson's disease sleep scale (PDSS) score were associated with depression in PD. female gender, higher rapid eye movement behavior disorder Questionnaire-Hong Kong (RBD-HK) score, higher Hamilton Deprssion Rating Scale (HAMD) score, higher the scale for outcomes in PD for autonomic symptoms (SCOPA-AUT)score and larger SN echogenic areas were associated with anxiety. Neither depression nor anxiety was related to any anti parkinsonism drugs. CONCLUSIONS: The prevalence of depression and anxiety in the current PD patients was 11.17% and 25.81% respectively. Disease of tumor, currently having no partner, severer motor function, dyskinesia, poorer sleep quality and anxiety were risk factors for PD with depression. Female, depression, rapid eye movement behavior disorder (RBD), autonomic dysfunction and larger SN area were risk factors for PD with anxiety. PMID- 29166865 TI - King's Health Partners' Prostate Cancer Biobank (KHP PCaBB). AB - The KHP PCaBB was established in 2013 and recruits donors from the Urology or Oncology Departments at Guy's Hospital in London (UK). Prostate cancer patients may be approached to give their consent for biobanking at any point in their treatment pathway, which allows residual material from their earlier diagnosis to be transferred and used by the Biobank. Currently, patients are specifically asked to donate samples of blood and surplus prostate tissue as well as permitting access to their clinical and pathological data that continues to be added throughout the course of their disease. Between 2013 and 2015, 549 prostate cancer patients gave their consent to the biobank and, the tissue repository collected 489 blood samples, 120 frozen prostate tissue samples and 1064 formalin fixed paraffin embedded diagnostic blocks.Prostate cancer has become a chronic disease in a large proportion of men, with many men receiving multiple subsequent treatments, and their treatment trajectory often spanning over decades. Therefore, this resource aims to provide an ideal research platform to explore potential variations in treatment response as well as disease markers in the different risk categories for prostate cancer.A recent audit of the KHP PCaBB revealed that between 2013 and 2015, 1796 patients were diagnosed with prostate cancer at King's Health Partners (KHP), out of which 549 (30.6%) gave their consent to KHP PCaBB. Comparisons between demographic and clinical characteristics of patients who had consented compared to the total patient population revealed that the KHP PCaBB is demographically representative of the total prostate cancer patient population seen in Guy's and St Thomas' NHS Foundation Trust (GSTT). We observed no differences in distribution of ethnicity (p = 0.507) and socioeconomic status (p = 0.097). Some differences were observed in clinical characteristics, specifically with treatment type - which differed significantly between the patients who had given consent and total patient population.The KHP PCaBB has thereby amassed a rich data and tissue repository that is largely reflective of both the demographic and clinical diversity within the total prostate cancer patient population seen at KHP, making it an ideal platform for prostate cancer research. PMID- 29166866 TI - The risk and survival outcome of subsequent primary colorectal cancer after the first primary colorectal cancer: cases from 1973 to 2012. AB - BACKGROUND: Among colorectal cancer (CRC) survivors, how the prior tumor location affects the risk of subsequent primary colorectal cancer (SPCRC) and the outcome of those suffering from SPCRC remain unknown. METHODS: CRC cases diagnosed from 1973 to 2012 were screened for SPCRC development using the Surveillance, Epidemiology, and End Results database. The relative risk of SPCRC was estimated using the standardized incidence ratio. Survivals were analyzed using the Kaplan Meier and Cox regression model. RESULTS: The overall risk of SPCRC increased by 27% in CRC survivors compared to that of the general population. The risk increased in patients with both prior right colon cancer (RCC) and left colon cancer (LCC), and was concentrated in the first 5 years after the prior diagnosis, and among young patients. Among the 6701 SPCRC patients identified, patients with prior RCC were more likely to be elderly, female, and with more low or undifferentiated disease than those with prior LCC or rectal cancer (ReC). The overall survivals differed by both prior tumor location (P < 0.0001) and age (P < 0.0001), and the difference by tumor location remained significant when adjusted or stratified by any other potential prognostic factor except age. The cancer specific survivals differed by age (P < 0.0001) rather than by prior tumor location (P = 0.455). CONCLUSIONS: The overall risk of SPCRC increased among patients with both prior RCC and LCC, but not among those with ReC. The different survival outcomes in CRC survivors suffering from SPCRC were largely explained by the patient age but not by the prior tumor location. PMID- 29166867 TI - Clinical and virological factors associated with gastrointestinal symptoms in patients with acute respiratory infection: a two-year prospective study in general practice medicine. AB - BACKGROUND: Gastrointestinal (GI) symptoms, such as diarrhea, vomiting, abdominal pain and nausea are not an uncommon manifestation of an acute respiratory infection (ARI). We therefore evaluated clinical and microbiological factors associated with the presence of GI symptoms in patients consulting a general practitioner (GP) for ARI. METHODS: Nasopharyngeal swabs, stool specimens and clinical data from patients presenting to GPs with an ARI were prospectively collected during two winter seasons (2014-2016). Samples were tested by quantitative real-time PCR for 12 respiratory pathogen groups and for 12 enteric pathogens. RESULTS: Two hundred and four of 331 included patients (61.6%) were positive for at least one respiratory pathogen. Sixty-nine stools (20.8%) were positive for at least one pathogen (respiratory and/or enteric). GI symptoms were more likely declared in case of laboratory confirmed-enteric infection (adjusted odds ratio (aOR) = 3.2; 95% confidence interval [CI] [1.2-9.9]; p = 0.02) or human coronavirus (HCoV) infection (aOR = 2.7; [1.2-6.8]; p = 0.02). Consumption of antipyretic medication before the consultation seemed to reduce the risk of developing GI symptoms for patients with laboratory-confirmed influenza (aOR = 0.3; [0.1-0.6]; p = 0.002). CONCLUSIONS: The presence of GI symptoms in ARI patients could not be explained by the detection of respiratory pathogens in stools. However, the detection of enteric pathogens in stool samples could explained by the presence of GI symptoms in some of ARI cases. The biological mechanisms explaining the association between the presence of HCoVs in nasopharynx and GI symptoms need to be explored. PMID- 29166868 TI - Prevalence of ESR1 E380Q mutation in tumor tissue and plasma from Japanese breast cancer patients. AB - BACKGROUND: ESR1 mutations have attracted attention as a potentially important marker and treatment target in endocrine therapy-resistant breast cancer patients. The E380Q mutation, which is one of the ESR1 mutations, is associated with estradiol (E2) hypersensitivity, increased DNA binding to the estrogen response element, and E2-independent constitutive trans-activation activity, but its frequency in ESR1 mutations remains unknown. The present study aimed to investigate the E380Q mutation in comparison with the other representative ESR1 mutations. METHODS: We screened a total of 62 patients (66 tumor tissues and 69 plasma cell-free DNA (cfDNA)) to detect ESR1 mutations (E380Q, Y537S, Y537N, Y537C, and D538G) using droplet-digital polymerase chain reaction. Plasma was collected at more than two points of the clinical course, in whom changes of ESR1 mutations under treatment were investigated. RESULTS: We detected ESR1 mutations in 21% (12/57) of MBCs. The E380Q ESR1 mutation was found in 16% (2/12) and the other ESR1 LBD mutations were five (41.6%) of Y537S, and four each (33.3%) of D538G, Y537N, and Y537C, in 12 ESR1 mutant breast cancer patients. Five tumors had multiple ESR1 mutations: three had double ESR1 mutations; Y537S/E380Q, Y37S/Y537C, and Y537S/D538G, and two had triple ESR1 mutations; Y537S/Y537N/D538G. In plasma cfDNA analysis, the E380Q mutation was not detected, but increases in other ESR1 mutations were detected in 46.2% (6/13) of MBC patients under treatment. CONCLUSIONS: We have shown that there are distinct populations of ESR1 mutations in metastatic tissue and plasma. Each ESR1 mutation may have different clinical significance, and it will be necessary to investigate them all. PMID- 29166869 TI - Multimodal imaging of retinal pigment epithelial detachments in patients with C3 glomerulopathy: case report and review of the literature. AB - BACKGROUND: To describe the optical coherence tomography angiograhy (OCTA) of drusenoid pigment epithelial detachments (PEDs) in a woman affected by Complement 3 (C3) glomerulopathy, which represents a spectrum of glomerular diseases characterized on fluorescent microscopy by C3 accumulation with absent, or scanty, immunoglobulin deposits. It is due to acquired or genetically defective alternative pathway control and is generally associated with drusen-like deposits in Bruch's membrane, as well as choriocapillaris. These retinal lesions can be associated with choroidal neovascularization and central serous chorioretinopathy (CSCR). OCTA is useful to detect neovascularization without injecting a contrast product, particularly in these patients who may have renal insufficiency. CASE PRESENTATION: A 28-year-old woman affected by C3 glomerulpathy was diagnosed with asymptomatic multiple bilateral PEDs during a routine ophthalmologic consultation. To better characterize the lesions, multimodal imaging was performed and included: optic coherence tomography (OCT), en-face OCT, OCTA, fluorescence and indocyanine angiography. The OCTA clearly identified vascular network rarefaction with decreased choriocapillary vascularization. It confirmed that PEDs associated with C3 glomerulonephritis are not vascularized, but rather of serous type. CONCLUSIONS: Patients affected by C3 glomerulopathy can develop neovascular membranes as retinal complications of pigment epithelial detachments. Optical coherence angiography may be indicated to identify this complication, without injecting any contrast product that could produce further kidney damage. PMID- 29166870 TI - Recruiting former melanoma patients via hospitals in comparison to office-based dermatologists in a register-based cohort study that required indirect contact. AB - BACKGROUND: There are detailed reviews about different recruitment strategies, but not with regard to differences between recruitment of hospital-based versus office-based physicians. Within this study, the two different recruitment schemes are compared. Advantages and disadvantages of different ways of recruitment in registry-based studies are discussed. METHODS: In a cross-sectional cancer registry-based study, long-term melanoma patients were contacted by dermatologists rather than directly by the registry on the basis of the legal situation. Logistic regression models and generalized estimating equations were used to assess effects of various patient and physician characteristics on participation and data quality. Especially differences between hospital-based versus office-based dermatologists are evaluated. RESULTS: Seventy two out of 112 contacted dermatologists took part in the study (64.3%). The cooperation proportion was 52.2% (689 participants/1320 contacted patients). Participants and non-participants differed regarding age and sex, but not regarding other social demographic factors and cancer stage. We did not observe a difference in patient participation between hospital-based versus office-based dermatologists (OR 1.08 [CI 0.84-1.39]; p = 0.57). However, medical data provided by the cancer registry were better for participants registered and recruited by hospitals. CONCLUSIONS: In cohort studies with epidemiological cancer registries, recruitment via physicians has potential disadvantages and is more complex. If this indirect way of contact is mandatory, we recommend recruitment procedures including hospital based rather than office-based physicians. However, physician characteristics were not associated with outcome. PMID- 29166871 TI - Contribution of diffusion-weighted imaging to conventional MRI for detection of haemorrhagic infarction in ovary torsion. AB - BACKGROUND: To assess the role of DWI in differentiation haemorrhagic ovary infarction from non-haemorrhagic one. METHODS: For this prospectively designed study, of 117 female patients who presented with acute lower quadrant pain and underwent MRI for suspicion of ovary torsion, results of only 29 patients (mean age, 24.7; SD, +/-5.7; age range, 18-37), with surgical and pathological confirmation of adnexal torsion, were included to the study. All patients underwent DWI after conventional MRI. Quantitative and qualitative analysis of both the torsed and contralateral normal ovary were performed. Results of conventional MRI and DWI were noted. RESULTS: At operation 15 patients were found to have haemorrhagic infarction while 14 had non-haemorrhagic infarction. Of the 29 patients, 17 torsed ovaries could be salvaged in a viable state. We found statistically significant correlation of the ADC values, between haemorrhagic and non-haemorrhagic ovary infarction. The ADC values were significantly lower in patients with haemorrhagic infarction than non-haemorrhagic ones (p < 0.001). Using an ADC threshold of 1.27, the sensitivity of DWI for haemorrhagic infarction was 0.93 and specificity 0.85. CONCLUSION: DWI may be used with a significant success for the preoperative diagnosis of haemorrhagic infarction. This may be alerting for pre-emptive surgery in avoiding serious complications and preventing irreversible structural damage of the ovary. PMID- 29166872 TI - Experiences of adult patients using primary care services in Poland - a cross sectional study in QUALICOPC study framework. AB - BACKGROUND: Patients as real healthcare system users are important observers of primary care and are able to provide reliable information about the quality of care. The aim of this study was to explore the patients' experiences and their level of satisfaction with the process and outcomes of care provided by primary care physicians in Poland and to identify the characteristics of the patients, their physicians, and facilities associated with patient satisfaction. METHODS: The study is based on data from the Polish part of the Quality and Costs of Primary Care in Europe (QUALICOPC) cross-sectional, questionnaire-based study. In Poland, a nationally representative sample of 220 PC physicians and 1980 of their patients were recruited to take part in the study. As a study tool we used 3 out of 4 QUALICOPC questionnaires: "Patient Experience", "PC Physician" and "Fieldworker" questionnaires. RESULTS: The areas of the best quality perceived by Polish PC patients are: equity, accessibility of care and quality of service. Coordination and comprehensiveness of care are evaluated relatively worse. The patients' and their physicians' characteristics have a limited influence on patient satisfaction and experiences with Polish primary care. CONCLUSIONS: Primary health care in Poland is of good overall quality as perceived by the patients. Study participants were at most satisfied with accessibility and equity of care and less satisfied with coordination and comprehensiveness of care. Longer patient-doctor relationship and older age of patients were found as the most influential determinants of higher satisfaction. However, variables used in this study poorly explain the overall level of satisfaction. Further research is needed to identify the other determinants of patient satisfaction in the Polish population. Rural practices deserve additional attention due to highest proportions of both extremely satisfied and dissatisfied patients. PMID- 29166873 TI - Mortality patterns and risk among older men and women with intellectual disability: a Swedish national retrospective cohort study. AB - BACKGROUND: Sweden has closed all institutions and imposed legislation to ensure service and support for individuals with intellectual disability (ID). Understanding mortality among older individuals with ID is essential to inform development of health promotion and disease control strategies. We investigated patterns and risk of mortality among older adults with ID in Sweden. METHODS: This retrospective cohort study compared older adults aged 55 years and older with ID with a control population. Participants were followed during 2002-2015 or death, and censored if they moved out of Sweden. Individuals with ID were identified from two national registers: one covering all specialist health-care visits (out-patient visits and hospitalisation) and the other covering people accessing social/support services. Individuals with ID (n = 15,289) were matched with a control population by sex, birth year, and year of first hospitalisation/out-patient visit/access to LSS services. Cause-of-death data were recorded using International Classification of Diseases, Tenth Revision. Cox proportional hazards regression were conducted to assess if overall and cause specific mortality rate among individuals with ID was higher than in the Swedish population. RESULTS: The overall mortality rate among individuals with ID was 2483 per 100,000 people compared with 810 in the control population. Among those who died, more individuals with ID were younger than 75 years and unmarried. Leading causes of death among individuals with ID were circulatory diseases (34%), respiratory diseases (17%) and neoplasms (15%). Leading causes of death in a sub-sample with Down syndrome (DS) were respiratory diseases (37%), circulatory diseases (26%) and mental/behavioural disorders (11%). Epilepsy and pneumonitis were more common among individuals with ID than controls. Alzheimer's disease was common in the control population and individuals with DS, but not among those with ID when DS was excluded. Individuals with ID had a higher overall mortality risk (hazard ratio [HR] 4.1, 95% confidence interval [CI] 4.0-4.3) and respiratory disease death risk (HR 12.5, 95% CI 10.9-14.2) than controls. CONCLUSION: Older adults with ID in Sweden carry a higher mortality risk compared with the general population, mainly attributable to respiratory, nervous and circulatory diseases. Care for this group, particularly during the terminal stage of illness, needs to be tailored based on understanding of their main health problem. PMID- 29166874 TI - Efficacy and safety of pertussis vaccination for pregnant women - a systematic review of randomised controlled trials and observational studies. AB - BACKGROUND: Worldwide, pertussis remains a major health problem among children. During the recent outbreaks of pertussis, maternal antenatal immunisation was introduced in several industrial countries. This systematic review aimed to synthesize evidence for the efficacy and safety of the pertussis vaccination that was given to pregnant women to protect infants from pertussis infection. METHODS: We searched literature in the Cochrane Central Register of Controlled Trials, Medline, Embase, and OpenGrey between inception of the various databases and 16 May 2016. The search terms included 'pertussis', 'whooping cough', 'pertussis vaccine,' 'tetanus, diphtheria and pertussis vaccines' and 'pregnancy' and 'perinatal'. RESULTS: We included 15 articles in this review, which represented 12 study populations, involving a total of 203,835 mother-infant pairs from the US, the UK, Belgium, Israel, and Vietnam. Of the included studies, there were two randomised controlled trials (RCTs) and the rest were observational studies. Existing evidence suggests that vaccinations administered during 19-37 weeks of gestation are associated with significantly increased antibody levels in the blood of both mothers and their newborns at birth compared to placebo or no vaccination. However, there is a lack of robust evidence to suggest whether these increased antibodies can also reduce the incidence of pertussis (one RCT, n = 48, no incidence in either group) and pertussis-related severe complications (one observational study) or mortality (no study) in infants. Meanwhile, there is no evidence of increased risk of serious complications such as stillbirth (e.g. one RCT, n = 103, RR = 0, meaning no case in the vaccine group), or preterm birth (two RCTs, n = 151, RR = 0.86, 95%CI: 0.14-5.21) related to administration of the vaccine during pregnancy. CONCLUSION: Given that pertussis infection is increasing in many countries and that newborn babies are at greatest risk of developing severe complications from pertussis, maternal vaccination in the later stages of pregnancy should continue to be supported while further research should fill knowledge gaps and strengthen evidence of its efficacy and safety. PMID- 29166875 TI - Associations of childhood maltreatment with pre-pregnancy obesity and maternal postpartum mental health: a cross-sectional study. PMID- 29166876 TI - Gastroesophageal flap valve reflected EGJ morphology and correlated to acid reflux. AB - OBJECTIVE: The anatomy of esophagogastric junction (EGJ) serves as the anti reflux barrier. The gastroesophageal flap valve (GEFV) is a component of EGJ. The aim of the current study was to assess its correlation with the esophageal acid exposure and the impact on anti-reflux barrier function by using the metrics of EGJ contraction. METHODS: Eighty three patients with typical GERD symptoms were included in the study. Upper endoscopy, high-resolution manometry (HRM) and 24 h multichannel intraluminal impedance-pH (MII-pH) monitoring were performed in all patients. GEFV was determined as four grades during endoscopic examination based on the Hill classification. The esophageal pressure topography (EPT) metrics defined in the updated Chicago Classification were measured by HRM, including integrated relaxation pressure (IRP), EGJ contractile index (EGJ-CI),expiratory EGJ pressure(EGJP-exp) and inspiratory EGJ pressure (EGJP-insp). RESULTS: The GEFV grade III and IV was more commonly found in patients with esophagitits (p < 0.05). The acid exposure time (AET%) and supine AET% were lower in patients with GEFV grade I (p < 0.01). There was weak correlation between AET% and GEFV grades (r = 0.27, p = 0.013). There were more EGJ morphology type III in patients with GEFV grade IV (p < 0.05).There were no significant differences on the values of four HRM metrics among the patients with different GEFV grades (p > 0.05). CONCLUSION: The GEFV grades were associated with acid reflux positively and could be a good reflection of EGJ morphology in HRM. But it had no impact on the four HRM metrics. Our research revealed that GEFV may play an assistant role in the anti-reflux barrier. PMID- 29166877 TI - A prospective study examining the role of myocardial Fibrosis in outcome following mitral valve repair IN DEgenerative mitral Regurgitation: rationale and design of the mitral FINDER study. AB - BACKGROUND: The optimal management of chronic severe primary degenerative mitral regurgitation (MR) is to repair the valve but identification of the optimal timing of surgery remains challenging. Current guidelines suggest 'watchful waiting' until the onset of symptoms or left ventricular (LV) dysfunction but these have been challenged as promoting 'rescue surgery'. Better predictors are required to inform decision-making in relation to the necessity and timing of surgery. Chronic volume overload is a stimulus for adverse adaptive LV remodelling. Subclinical reduction in LV strain before mitral repair predicts a fall in LV ejection fraction following surgery and is thought to reflect the development of myocardial fibrosis in response to chronic volume overload. Myocardial fibrosis can be detected non-invasively using cardiac magnetic resonance (CMR) imaging techniques as an expansion of the extracellular volume (ECV). METHODS/DESIGN: This study investigates whether: 1) patients with above median ECV will have smaller reduction in end-systolic volume index (as a measure of the degree of reverse LV remodelling) on CMR following mitral valve repair, compared to those with below median ECV; and 2) higher ECV on CMR, validated through histology, adversely impacts upon post-operative complications and symptomatic improvement following surgery. This is a multi-centre, prospective, cross-sectional comparison of patients prior to and 9 months following surgery for chronic severe primary degenerative MR. To establish the natural history of ECV in MR, an additional cohort of patients with asymptomatic MR who do not wish to consider early repair will be followed. Investigations include CMR, cardiopulmonary exercise test, stress echocardiography, signal-averaged electrocardiogram, 24-h electrocardiogram monitoring, laboratory tests and patient-reported outcome measures. Patients undergoing surgery will have cardiac biopsies performed at the time of mitral valve repair for histological quantification of fibrosis. DISCUSSION: This study will advance our understanding of ventricular remodelling in MR, its impact on patient symptoms and ventricular response following surgery. Establishing the link between myocardial fibrosis (measured on CMR and validated through histology), with early ventricular dysfunction, will offer physicians a novel non-invasive biomarker that can further inform the timing of surgery. TRIAL REGISTRATION: This trial was registered at ClinicalTrials.gov ( NCT02355418 ) on 30th November 2015. PMID- 29166878 TI - The ANDROMEDA prospective cohort study: predictive value of combined criteria to tailor breast cancer screening and new opportunities from circulating markers: study protocol. AB - BACKGROUND: In recent years growing interest has been posed on alternative ways to screen women for breast cancer involving different imaging techniques or adjusting screening interval by breast cancer risk estimates. A new research area is studying circulating microRNAs as molecular biomarkers potentially useful for non invasive early detection together with the analysis of single-nucleotide polymorphisms (SNPs). The Andromeda study is a prospective cohort study on women attending breast cancer screening in a northern Italian area. The aims of the study are: 1) to define appropriate women risk-based stratifications for personalized screening considering different factors (reproductive, family and biopsy history, breast density, lifestyle habits); 2) to evaluate the diagnostic accuracy of selected circulating microRNAs in a case-control study nested within the above mentioned cohort. METHODS: About 21,000 women aged 46-67 years compliant to screening mammography are expected to be enrolled. At enrolment, information on well-known breast cancer risk factors and life-styles habits are collected through self-admistered questionnaires. Information on breast density and anthropometric measurements (height, weight, body composition, and waist circumference) are recorded. In addition, women are requested to provide a blood sample for serum, plasma and buffy-coat storing for subsequent molecular analyses within the nested case-control study. This investigation will be performed on approximately 233 cases (screen-detected) and 699 matched controls to evaluate SNPs and circulating microRNAs. The whole study will last three years and the cohort will be followed up for ten years to observe the onset of new breast cancer cases. DISCUSSION: Nowadays women undergo the same screening protocol, independently of their breast density and their individual risk to develop breast cancer. New criteria to better stratify women in risk groups could enable the screening strategies to target high-risk women while reducing interventions in those at low-risk. In this frame the present study will contribute in identifying the feasibility and impact of implementing personalized breast cancer screening.

Walp.) is the most important food and forage legume in the semi-arid tropics of sub-Saharan Africa where approximately 80% of worldwide production takes place primarily on low-input, subsistence farm sites. Among the major goals of cowpea breeding and improvement programs are the rapid manipulation of agronomic traits for seed size and quality and improved resistance to abiotic and biotic stresses to enhance productivity. Knowing the suite of transcription factors (TFs) and transcriptionally active proteins (TAPs) that control various critical plant cellular processes would contribute tremendously to these improvement aims. RESULTS: We used a computational approach that employed three different predictive pipelines to data mine the cowpea genome and identified over 4400 genes representing 136 different TF and TAP families. We compare the information content of cowpea to two evolutionarily close species common bean (Phaseolus vulgaris), and soybean (Glycine max) to gauge the relative informational content. Our data indicate that correcting for genome size cowpea has fewer TF and TAP genes than common bean (4408 / 5291) and soybean (4408/ 11,065). Members of the GROWTH-REGULATING FACTOR (GRF) and Auxin/indole-3-acetic acid (Aux/IAA) gene families appear to be over-represented in the genome relative to common bean and soybean, whereas members of the MADS (Minichromosome maintenance deficient 1 (MCM1), AGAMOUS, DEFICIENS, and serum response factor (SRF)) and C2C2-YABBY appear to be under-represented. Analysis of the AP2-EREBP APETALA2-Ethylene Responsive Element Binding Protein (AP2-EREBP), NAC (NAM (no apical meristem), ATAF1, 2 (Arabidopsis transcription activation factor), CUC (cup-shaped cotyledon)), and WRKY families, known to be important in defense signaling, revealed changes and phylogenetic rearrangements relative to common bean and soybean that suggest these groups may have evolved different functions. CONCLUSIONS: The availability of detailed information on the coding capacity of the cowpea genome and in particular the various TF and TAP gene families will facilitate future comparative analysis and development of strategies for controlling growth, differentiation, and abiotic and biotic stress resistances of cowpea. PMID- 29166880 TI - Is the policy of allowing a female labor companion feasible in developing countries? Results from a cross sectional study among Sri Lankan practitioners. AB - BACKGROUND: Companionship during labor is known to have both physical and psychosocial benefits to mother and baby. Sri Lanka made a policy decision to allow a labour companion in 2011. However, implementation has been unsatisfactory. Given the leading role Obstetricians play in the implementation of policy, a study was undertaken to assess the knowledge, attitudes and practices among them. METHOD: A descriptive cross sectional study was conducted among consultant obstetricians working in the state hospitals using the platform 'Survey Monkey'. RESULTS: Out of the 140 consultant obstetricians invited, 68(48.5%) participated. Among the study participants, 40 (58.8%) did not allow labour companions in their wards. Lack of space (n = 32; 80%) and the volume of work in the labor wards (n = 22; 55%) were the commonest reasons for not allowing a companion. Only 16.7% (n = 5) of the obstetricians handling more than 300 deliveries per month allowed a companion (p = 0.001). Less than 50% of the obstetricians were aware of the advantages associated with the practice such as shorter labor, lesser analgesic requirement, higher chances of a normal birth, improved neonatal outcome and reduced requirements for labor augmentation for slow progress of labor. Knowledge on advantages on breast feeding and reduced need of instrumental delivery also remained low. CONCLUSION: In an individual unit, the consultant often decides policy. The study points out the need to improve awareness among the practitioners. PMID- 29166881 TI - Mitochondrial pyruvate carrier 1 mediates abscisic acid-regulated stomatal closure and the drought response by affecting cellular pyruvate content in Arabidopsis thaliana. AB - BACKGROUND: Stomata are micropores surrounded by pairs of guard cells, and their opening is finely controlled to balance water vapor loss as transpiration and CO2 absorption for photosynthesis. The regulatory signaling network for stomatal movement is complicated, and increasing numbers of new genes have been shown to be involved in this process. Our previous study indicated that a member of the plant putative mitochondrial pyruvate carrier (MPC) family, NRGA1, is a negative regulator of guard cell abscisic acid (ABA) signaling. In this study, we identified novel physiological roles of pyruvate and MPC1, another member of the MPC family, in the regulation of stomatal closure in Arabidopsis. RESULTS: Loss of-function mutants of MPC1 (mpc1) were hypersensitive to ABA-induced stomatal closure and ABA-activated guard cell slow-type anion currents, and showed a reduced rate of water loss upon drought treatment compared with wild-type plants. In contrast, plants overexpressing MPC1 showed a hyposensitive ABA response and increased sensitivity to drought stress. In addition, mpc1 mutants accumulated more pyruvate after drought or ABA treatment. The increased pyruvate content also induced stomatal closure and activated the slow-type anion channels of guard cells, and this process was dependent on the function of RbohD/F NADPH oxidases and reactive oxygen species concentrations in guard cells. CONCLUSIONS: Our findings revealed the essential roles of MPC1 and pyruvate in stomatal movement and plant drought resistance. PMID- 29166882 TI - Polymorphisms in ADH1B and ALDH2 genes associated with the increased risk of gastric cancer in West Bengal, India. AB - BACKGROUND: Gastric cancer (GC) is one of the most frequently diagnosed digestive tract cancers and carries a high risk of mortality. Acetaldehyde (AA), a carcinogenic intermediate of ethanol metabolism contributes to the risk of GC. The accumulation of AA largely depends on the activity of the major metabolic enzymes, alcohol dehydrogenase and aldehyde dehydrogenase encoded by the ADH (ADH1 gene cluster: ADH1A, ADH1B and ADH1C) and ALDH2 genes, respectively. This study aimed to evaluate the association between genetic variants in these genes and GC risk in West Bengal, India. METHODS: We enrolled 105 GC patients (cases), and their corresponding sex, age and ethnicity was matched to 108 normal individuals (controls). Genotyping for ADH1A (rs1230025), ADH1B (rs3811802, rs1229982, rs1229984, rs6413413, rs4147536, rs2066702 and rs17033), ADH1C (rs698) and ALDH2 (rs886205, rs968529, rs16941667 and rs671) was performed using DNA sequencing and RFLP. RESULTS: Genotype and allele frequency analysis of these SNPs revealed that G allele of rs17033 is a risk allele (A vs G: OR = 3.67, 95% CI = 1.54-8.75, p = 0.002) for GC. Significant association was also observed between rs671 and incidence of GC (p = 0.003). Moreover, smokers having the Lys allele of rs671 had a 7-fold increased risk of acquiring the disease (OR = 7.58, 95% CI = 1.34-42.78, p = 0.009). CONCLUSION: In conclusion, rs17033 of ADH1B and rs671 of ALDH2 SNPs were associated with GC risk and smoking habit may further modify the effect of rs671. Conversely, rs4147536 of ADH1B might have a protective role in our study population. Additional studies with a larger patient population are needed to confirm our results. PMID- 29166883 TI - The humanistic burden of Pompe disease: are there still unmet needs? A systematic review. AB - BACKGROUND: Humanistic burden considers the impact of an illness on a patient's health-related quality of life (HRQoL), activities of daily living (ADL), caregiver health, and caregiver QoL. Humanistic burden also considers treatment satisfaction and adherence to treatment regimens. Pompe disease is an autosomal recessive, progressive, multisystemic neuromuscular disease. Approval of enzyme replacement therapy (ERT) markedly improved prognosis for patients, but considerable morbidity and a substantial humanistic burden remain. This article characterizes the humanistic burden of Pompe disease through a systematic literature review. METHODS: A systematic search of MEDLINE(r) and Embase(r) with back-referencing and supplementary literature searches was performed to retrieve data from interventional and non-interventional studies on the humanistic burden of Pompe disease. Publications were screened according to predefined criteria, extracted, and assessed for quality. Extracted data were narratively synthesized. RESULTS: No publications on the humanistic burden of infantile-onset Pompe disease (IOPD) were identified. As such, of 17 publications included here, all are in patients with late-onset Pompe disease (LOPD). Thirteen publications were initiated after approval of ERT, two were initiated before, and two overlapped the approval of ERT. The review shows that LOPD patients have a significantly lower HRQoL than the general population, even if treated with ERT. On transitioning to ERT, treatment was associated with improvement in the physical component score of the SF-36 and fatigue, although the SF-36 mental component score remained stable. Physical HRQoL remained below population norms after 4 years of ERT. Significantly more ERT-treated patients reported pain than controls, and bodily pain worsened in later years following ERT initiation. Treatment-naive LOPD patients had significantly poorer ADL functioning compared with the general population, although ERT stabilized deteriorating functioning impairment. ERT studies showed caregivers provide 17.7 h/week informal care on average. Fifty percent, 40% and <20% of caregivers reported mental health, physical health, and financial/relational problems, respectively. In ERT-naive patients, wheelchair use and home ventilatory support was associated with lower physical HRQoL and ADL functioning. In ERT-treated patients, key factors predicting worse HRQoL and ADL functioning were higher respiratory distress, poorer sleep quality, greater pain, and more fatigue. CONCLUSIONS: Pompe disease has a substantial humanistic burden, with strong inter-relationships among and between humanistic burden parameters and clinical progression. PMID- 29166884 TI - Gray matter morphological anomalies in the cerebellar vermis in first-episode schizophrenia patients with cognitive deficits. AB - BACKGROUND: Cognitive deficits are a core feature of early schizophrenia. However, the pathological foundations underlying cognitive deficits are still unknown. The present study examined the association between gray matter density and cognitive deficits in first-episode schizophrenia. METHOD: Structural magnetic resonance imaging of the brain was performed in 34 first-episode schizophrenia patients and 21 healthy controls. Patients were divided into two subgroups according to working memory task performance. The three groups were well matched for age, gender, and education, and the two patient groups were also further matched for diagnosis, duration of illness, and antipsychotic treatment. Voxel-based morphometric analysis was performed to estimate changes in gray matter density in first-episode schizophrenia patients with cognitive deficits. The relationships between gray matter density and clinical outcomes were explored. RESULTS: Patients with cognitive deficits were found to have reduced gray matter density in the vermis and tonsil of cerebellum compared with patients without cognitive deficits and healthy controls, decreased gray matter density in left supplementary motor area, bilateral precentral gyrus compared with patients without cognitive deficits. Classifier results showed GMD in cerebellar vermis tonsil cluster could differentiate SZ-CD from controls, left supplementary motor area cluster could differentiate SZ-CD from SZ-NCD. Gray matter density values of the cerebellar vermis cluster in patients groups were positively correlated with cognitive severity. CONCLUSIONS: Decreased gray matter density in the vermis and tonsil of cerebellum may underlie early psychosis and serve as a candidate biomarker for schizophrenia with cognitive deficits. PMID- 29166885 TI - The impact of rheumatologist-performed ultrasound on diagnosis and management of inflammatory arthritis in routine clinical practice. AB - BACKGROUND: Rheumatologists increasingly perform ultrasound (US) imaging to aid diagnosis and management decisions. There is a need to determine the role of US in facilitating early diagnosis of inflammatory arthritis. This study describes the impact of US use by rheumatologists on diagnosis and management of inflammatory arthritis in routine UK clinical practice. METHODS: We conducted a prospective study in four secondary care rheumatology clinics, each with one consultant who routinely used US and one who did not. Consenting patients aged > 18, newly referred with suspected inflammatory arthritis were included. Data were collected both retrospectively from medical records and via a prospectively completed physician questionnaire on US use. Analyses were stratified by US/non US groups and by sub-population of rheumatoid arthritis (RA)-diagnosed patients. RESULTS: 258 patients were included; 134 US and 124 non-US. 42% (56/134) of US and 47% (58/124) of non-US were diagnosed with RA. Results described for US and non-US cohorts, respectively as follows. The proportion of patients diagnosed at their first clinic visit was 37% vs 19% overall (p = 0.004) and 41% vs 19% in RA diagnosed patients (p = 0.01). The median time to diagnosis (months) was 0.85 vs 2.00 (overall, p = 0.0046) and 0.23 vs 1.38 (RA-diagnosed, p = 0.0016). Median time (months) to initiation on a DMARD (where initiated) was 0.62 vs 1.41 (overall, p = 0.0048) and 0.46 vs 1.81 (RA-diagnosed, p = 0.0007). CONCLUSION: In patients with suspected inflammatory arthritis, routine US use in newly referred patients seems to be associated with significantly earlier diagnosis and DMARD initiation. PMID- 29166886 TI - Trends in cardiovascular risk factors among U.S. men and women with and without diabetes, 1988-2014. AB - BACKGROUND: Studies evidenced that reduction in cardiovascular disease (CVD) mortality in diabetic patients can be attributed to improvements in major CVD risk factors and evidence-based treatments. Furthermore, studies showed that the relative risk of CVD mortality associated with diabetes compared with non diabetes is stronger in women than in men. Hence, we aimed to examine trends in CVD risk factors and intervention measures by sex and diabetic status. METHODS: Analysis of 5 distinct cross-sectional National Health and Nutrition Examination Surveys, 1988-1994, 1999-2002, 2003-2006, 2007-2010, and 2010-2014. Since detailed information on nontraditional risk factors such as sleep apnea was not available in each NHANES survey, traditional CVD risk factors including obesity, hypertension, and dyslipidemia were assessed in the study. To assess whether changes throughout the 27-year period differed by diabetes status, a logistic regression analysis was utilized to examine potential interaction effects between survey and diabetes. The similar process was repeated for sex. RESULTS: Means of all risk factors except body mass index and waist circumference decreased and the prevalence of antihypertensive and lipid-lowering medication use increased over time among diabetic and non-diabetic men and women. For both men and women, survey * diabetes status interaction terms for changes in HDL-cholesterol and triglyceride levels were not statistically significant, while the prevalence of antihypertensive and lipid-lowering medication use increased more in diabetic than in non-diabetic persons (all P < 0.001). For women, survey * diabetes status interaction terms indicated that compared with the first survey, total cholesterol, LDL-cholesterol, and non-HDL-cholesterol fallen more in diabetic than in non-diabetic persons (all P < 0.001). In the diabetic state, men experienced similar changes in means of all CVD risk factors and the prevalence of antihypertensive and lipid-lowering medication use as women (all P for interactions between survey and sex were >0.01). CONCLUSIONS: The major traditional CVD risk factors in diabetic men decreased to the same extent that they did for non-diabetic men. The magnitude of changes in the favorable trends in diabetic women was of similar or greater compared with those among non diabetic women. Diabetic women had as good an improvement in CVD risk factors as diabetic men. PMID- 29166887 TI - Self-confidence and knowledge of German ICU physicians in palliative care - a multicentre prospective study. AB - BACKGROUND: Little is known about ICU physicians' self-confidence and knowledge related to palliative care. Our objective was to investigate self-confidence and knowledge of German ICU physicians related to palliative care, and to assess the impact of work experience, gender, specialty and additional certifications in pain or palliative medicine. METHODS: In a multicentre prospective observational study ICU physicians of ten hospitals were asked to rate their self-confidence and to complete a multiple choice questionnaire for the assessment of knowledge. Beyond descriptive statistics and non-parametric tests for group comparisons, linear regression analysis was used to assess the impact of independent variable on self-confidence and knowledge. Spearman's rank test was calculated. RESULTS: 55% of answers in the knowledge test were correct and more than half of the participants rated themselves as "rather confident" or "confident". Linear regression analysis revealed that an additional certificate in either pain or palliative medicine significantly increased both knowledge and self-confidence, but only 15 out of 137 participants had at least one of those certificates. Relation between self-confidence and the results of the knowledge test was weak (r = 0.270 in female) and very weak (r = -0.007 in male). CONCLUSIONS: Although the questionnaire needs improvement according to the item analysis, it appears that, with respect to palliative care, ICU Physicians' self-confidence is not related to their knowledge. An additional certificate in either pain or palliative medicine was positively correlated to both self-confidence and knowledge. However, only a minority of the participants were qualified through such a certificate. PMID- 29166888 TI - Cyclic stretch induced-retinal pigment epithelial cell apoptosis and cytokine changes. AB - BACKGROUND: The pathogenesis of age-related macular degeneration (AMD) is complex. It has been shown that vitreomacular traction (VMT) plays a role in the pathogenesis of AMD. We speculate that the continuous stretch induced by VMT might impair the function of retinal pigment epithelium (RPE) cells and it might also be involved in the progression of AMD. METHODS: Cultured ARPE-19 cells were subjected to cyclic stretch on the Flexcell Strain system at a level of 25% increment on the surface area for 8 h, 14 h, 20 h, 24 h. In another group, the stretch was withdrawn at 14 h and the cell cultured for another 6 h. Then, we observed the changes in morphology, apoptosis and expression of interleukin 6 (IL6) and vascular endothelial growth factor (VEGF) in RPE cells under stretch. RESULTS: We found that stretch induced the RPE cells to change from a spreading shape into a rounded shape, and that the morphological changes were positively correlated with the duration of the stretch. The expression of pFAK397 and pRac1/cdc42 were elevated in a time-dependent fashion. The stretch resulted in an increase in the apoptosis ratio, with Bcl2, Bax and p53 also showing time dependent changes. In addition, up-regulation of IL6 and VEGF expression levels was also observed. After withdrawal of the stretch, all of these changes were significantly diminished. CONCLUSION: Stretch may induce morphological, cell apoptosis, and up-regulation of cytokines changes in RPE cells, indicating that cyclic stretching may participate in the progression of AMD by impeding the functions of the RPE. PMID- 29166889 TI - Overweight and obesity prevalence among Cree youth of Eeyou Istchee according to three body mass index classification systems. AB - BACKGROUND: Little is known about the suitability of three commonly used body mass index (BMI) classification systems for Indigenous youth. We estimated overweight and obesity prevalence among Cree youth of Eeyou Istchee according to three BMI classification systems, assessed the level of agreement between them, and evaluated their accuracy through body fat and cardiometabolic risk factors. METHODS: Data on 288 youth (aged 8-17 years) were collected. Overweight and obesity prevalence were estimated with Centers for Disease Control and Prevention (CDC), International Obesity Task Force (IOTF) and World Health Organization (WHO) criteria. Agreement was measured with weighted kappa (kappaw). Associations with body fat and cardiometabolic risk factors were evaluated by analysis of variance. RESULTS: Obesity prevalence was 42.7% with IOTF, 47.2% with CDC, and 49.3% with WHO criteria. Agreement was almost perfect between IOTF and CDC (kappaw = 0.93), IOTF and WHO (kappaw = 0.91), and WHO and CDC (kappaw = 0.94). Means of body fat and cardiometabolic risk factors were significantly higher (P trend < 0.001) from normal weight to obesity, regardless of the system used. Youth considered overweight by IOTF but obese by CDC or WHO exhibited less severe clinical obesity. CONCLUSIONS: IOTF seems to be more accurate in identifying obesity in Cree youth. PMID- 29166890 TI - Continuous passive motion and physical therapy (CPM) versus physical therapy (PT) versus delayed physical therapy (DPT) after surgical release for elbow contractures; a study protocol for a prospective randomized controlled trial. AB - BACKGROUND: The elbow is prone to stiffness after trauma. To regain functional elbow motion several conservative- and surgical treatment options are available. Conservative treatment includes physical therapy, intra-articular injections with corticosteroids and a static progressive or dynamic splinting program. If conservative treatment fails, an operative release of the posttraumatic stiff elbow is often performed. The best Evidence-Based rehabilitation protocol for patients after an operative release is unknown to date and differs per surgeon, hospital and country. Options include early- or delayed motion supervised by a physical therapist, immediate continuous passive motion (CPM), (night) splinting and a static progressive or dynamic splinting program. METHODS/DESIGN: The SET Study (Stiff Elbow Trial) is a single-centre, prospective, randomized controlled trial. The primary objective of this study is to compare the active Range of Motion (ROM) (flexion arc and rotational arc) twelve months after surgery between three groups. The first group will receive in-hospital CPM in combination with early motion Physical Therapy (PT) supervised by a physical therapist, the second group will receive only in-hospital early motion PT supervised by a physical therapist and the third group will receive outpatient supervised PT from postoperative day seven till ten. Secondary outcome measures will be Patient Reported Outcome Measures (PROMs) including the Mayo Elbow Performance Score (MEPS), the Oxford Elbow Score (OES), the quick Disabilities of Arm, Shoulder and Hand (qDASH) score, Visual Analogue pain Scale in rest and activity (VAS), Pain Catastrophizing Scale (PCS), the Short Form (SF)-36, the Centre for Epidemiological Studies Depression Scale Revised (CESD-R) and the Work Rehabilitation Questionnaire (WORQ) for the upper limb. DISCUSSION: A successful completion of this trial will provide evidence on the best rehabilitation protocol in order to (re)gain optimal motion after surgical release of the stiff elbow. TRIAL REGISTRATION: The trial is registered at the Dutch Trial Register: NTR6067 , 31-8-2016. PMID- 29166891 TI - Pediatric hospital admissions in Indigenous children: a population-based study in remote Australia. AB - BACKGROUND: We analysed hospital admissions of a predominantly Aboriginal cohort of children in the remote Fitzroy Valley in Western Australia during the first 7 years of life. METHODS: All children born between January 1, 2002 and December 31, 2003 and living in the Fitzroy Valley in 2009-2010 were eligible to participate in the Lililwan Project. Of 134 eligible children, 127 (95%) completed Stage 1 (interviews of caregivers and medical record review) in 2011 and comprised our cohort. Lifetime (0-7 years) hospital admission data were available and included the dates, and reasons for admission, and comorbidities. Conditions were coded using ICD-10-AM discharge codes. RESULTS: Of the 127 children, 95.3% were Indigenous and 52.8% male. There were 314 admissions for 424 conditions in 89 (70.0%) of 127 children. The 89 children admitted had a median of five admissions (range 1-12). Hospitalization rates were similar for both genders (p = 0.4). Of the admissions, 108 (38.6%) were for 56 infants aged <12 months (median = 2.5, range = 1-8). Twelve of these admissions were in neonates (aged 0-28 days). Primary reasons for admission (0-7 years) were infections of the lower respiratory tract (27.4%), gastrointestinal system (22.7%), and upper respiratory tract (11.4%), injury (7.0%), and failure to thrive (5.4%). Comorbidities, particularly upper respiratory tract infections (18.1%), failure to thrive (13.6%), and anaemia (12.7%), were common. In infancy, primary cause for admission were infections of the lower respiratory tract (40.8%), gastrointestinal (25.9%) and upper respiratory tract (9.3%). Comorbidities included upper respiratory tract infections (33.3%), failure to thrive (18.5%) and anaemia (18.5%). CONCLUSION: In the Fitzroy Valley 70.0% of children were hospitalised at least once before age 7 years and over one third of admissions were in infants. Infections were the most common reason for admission in all age groups but comorbidities were common and may contribute to need for admission. Many hospitalizations were feasibly preventable. High admission rates reflect disadvantage, remote location and limited access to primary healthcare and outpatient services. Ongoing public health prevention initiatives including breast feeding, vaccination, healthy diet, hygiene and housing improvements are crucial, as is training of Aboriginal Health Workers to increase services in remote communities. PMID- 29166892 TI - In vitro cytotoxic activity of medicinal plants from Nigeria ethnomedicine on Rhabdomyosarcoma cancer cell line and HPLC analysis of active extracts. AB - BACKGROUND: Cancer is a leading cause of death world-wide, with approximately 17.5 million new cases and 8.7 million cancer related deaths in 2015. The problems of poor selectivity and severe side effects of the available anticancer drugs, have demanded the need for the development of safer and more effective chemotherapeutic agents. The present study was aimed at determining the cytotoxicities of 31 medicinal plants extracts, used in Nigerian ethnomedicine for the treatment of cancer. METHODS: The plant extracts were screened for cytotoxicity, using the brine shrimp lethality assay (BSLA) and MTT cytotoxicity assay. Rhabdomyosarcoma (RD) cell line, normal Vero cell line and the normal prostate (PNT2) cell line were used for the MTT assay, while Artemia salina nauplii was used for the BSLA. The phytochemical composition of the active plant extracts was determined by high performance liquid chromatography (HPLC) analysis. RESULTS: The extract of Eluesine indica (L.) Gaertn (Poaceae), with a LC50 value of 76.3 MUg/mL, had the highest cytotoxicity on the brine shrimp larvae compared to cyclophosphamide (LC50 = 101.3 MUg/mL). Two plants extracts, Macaranga barteri Mull. Arg. (Euphorbiaceae) and Calliandra portoricensis (Jacq.) Benth (Leguminosae) exhibited significant cytotoxic activity against the RD cell line and had comparable lethal activity on the brine shrimps. Further cytotoxic investigation showed that the dichloromethane fraction of Macaranga barteri (DMB) and the ethyl acetate fraction of Calliandra portoricensis (ECP), exhibited approximately 6-fold and 4-fold activity, respectively, compared to cyclophosphamide on RD cell line. Determination of selective index (SI) using Vero and PNT2 cell line indicated that DMB and ECP displayed a high degree of selectivity against the cancer cell under investigation. HPLC analysis showed that 3,5dicaffeoylquinic acid, acteoside, kampferol-7-O-glucoside and bastadin 11 were the major components of DMB while the major components of ECP were neurolenin B, nigrosporolide and trans-geranic acid. CONCLUSION: The results demonstrate the cytotoxicity of Macaranga barteri and Calliandra portoricensis extracts, which are used in Nigerian folklore for cancer treatment. PMID- 29166893 TI - The effectiveness of interventions aimed at increasing physical activity in adults with persistent musculoskeletal pain: a systematic review and meta analysis. AB - BACKGROUND: Individuals with persistent musculoskeletal pain (PMP) have an increased risk of developing co-morbid health conditions and for early-mortality compared to those without pain. Despite irrefutable evidence supporting the role of physical activity in reducing these risks; there has been limited synthesis of the evidence, potentially impacting the optimisation of these forms of interventions. This review examines the effectiveness of interventions in improving levels of physical activity and the components of these interventions. METHODS: Randomised and quasi-randomised controlled trials were included in this review. The following databases were searched from inception to March 2016: CENTRAL in the Cochrane Library, Cochrane Database of Systematic Reviews (CDSR), MEDLINE, Embase, CINAHL, PsycINFO and AMED. Two reviewers independently screened citations, assessed eligibility, extracted data, assessed risk of bias and coded intervention content using the behaviour change taxonomy (BCTTv1) of 93 hierarchically clustered techniques. GRADE was used to rate the quality of the evidence. RESULTS: The full text of 276 articles were assessed for eligibility, twenty studies involving 3441 participants were included in the review. Across the studies the mean number of BCTs coded was eight (range 0-16); with 'goal setting' and 'instruction on how to perform the behaviour' most frequently coded. For measures of subjective physical activity: interventions were ineffective in the short term, based on very low quality evidence; had a small effect in the medium term based on low quality evidence (SMD 0.25, 95% CI 0.01 to 0.48) and had a small effect in the longer term (SMD 0.21 95% CI 0.08 to 0.33) based on moderate quality evidence. For measures of objective physical activity: interventions were ineffective - based on very low to low quality evidence. CONCLUSIONS: There is some evidence supporting the effectiveness of interventions in improving subjectively measured physical activity however, the evidence is mostly based on low quality studies and the effects are small. Given the quality of the evidence, further research is likely/very likely to have an important impact on our confidence in effect estimates and is likely to change the estimates. Future studies should provide details on intervention components and incorporate objective measures of physical activity. PMID- 29166894 TI - How do public health professionals view and engage with research? A qualitative interview study and stakeholder workshop engaging public health professionals and researchers. AB - BACKGROUND: With increasing financial pressures on public health in England, the need for evidence of high relevance to policy is now stronger than ever. However, the ways in which public health professionals (PHPs) and researchers relate to one another are not necessarily conducive to effective knowledge translation. This study explores the perspectives of PHPs and researchers when interacting, with a view to identifying barriers to and opportunities for developing practice that is effectively informed by research. METHODS: This research focused on examples from two responsive research schemes, which provide university-based support for research-related enquiries from PHPs: the NIHR SPHR Public Health Practitioner Evaluation Scheme1 and the responsive research service AskFuse2. We examined enquiries that were submitted to both between 2013 and 2015, and purposively selected eight enquiries for further investigation by interviewing the PHPs and researchers involved in these requests. We also identified individuals who were eligible to make requests to the schemes but chose not to do so. In-depth interviews were conducted with six people in relation to the PHPES scheme, and 12 in relation to AskFuse. The interviews were transcribed and analysed using thematic framework analysis. Verification and extension of the findings were sought in a stakeholder workshop. RESULTS: PHPs recognised the importance of research findings for informing their practice. However, they identified three main barriers when trying to engage with researchers: 1) differences in timescales; 2) limited budgets; and 3) difficulties in identifying appropriate researchers. The two responsive schemes addressed some of these barriers, particularly finding the right researchers to work with and securing funding for local evaluations. The schemes also supported the development of new types of evidence. However, other barriers remained, such as differences in timescales and the resources needed to scale-up research. CONCLUSIONS: An increased mutual awareness of the structures and challenges under which PHPs and researchers work is required. Opportunities for frequent and meaningful engagement between PHPs and researchers can help to overcome additional barriers to co-production of evidence. Collaborative models, such as the use of researchers embedded in practice might facilitate this; however, flexible research funding schemes are needed to support these models. PMID- 29166895 TI - Retrospective data on causes of childhood vision impairment in Eritrea. AB - BACKGROUND: Proper information on causes of childhood vision loss is essential in developing appropriate strategies and programs to address such causes. This study aimed at identifying the causes of vision loss in children attending the national referral eye hospital with the only pediatric ophthalmology service in Eritrea. METHODS: A retrospective data review was conducted for all the children (< 16 years of age) who attended Berhan Aiyni National Referral Eye Hospital in five years period from January 2011 to December 2015. Causes of vision loss for children with vision impairment (recorded visual acuity less than 6/18 for distance in the better eye) was classified by the anatomical site affected and by underlying etiology based on the timing of the insult and causal factor. RESULTS: The medical record cards of 22,509 children were reviewed, of whom 249 (1.1%) were visually impaired. The mean age of the participants was 7.82 +/- 5.43 years (range: one month to 16 years) and male to female ratio was 1:0.65. The leading causes of vision loss were cataract (19.7%), corneal scars (15.7%), refractive error and amblyopia (12.1%), optic atrophy (6.4%), phthisis bulbi (6.4%), aphakia (5.6%) and glaucoma (5.2%). Childhood factors including trauma were the leading causes identified (34.5%) whereas other causes included hereditary factors (4%), intrauterine factors (2.0%) and perinatal factors (4.4%). In 55.0% of the children, the underlying etiology could not be attributed. Over two-thirds (69.9%) of vision loss was potentially avoidable in nature. CONCLUSION: This study explored the causes of vision loss in Eritrean children using hospital based data. Cataract corneal opacities, refractive error and amblyopia, globe damage due to trauma, infection and nutritional deficiency, retinal disorders, and other congenital abnormalities were the leading causes of childhood vision impairment in children attending the tertiary eye hospital in Eritrea. As majority of the causes of vision loss was due to avoidable causes, we recommended primary level public health strategies to prevent ocular injuries, vitamin A deficiency, perinatal infections and retinopathy of prematurity as well as specialist pediatric eye care facilities for cataract, refractive errors, glaucoma and rehabilitative services to address childhood vision loss in Eritrea. PMID- 29166896 TI - Graph-theoretical comparison of normal and tumor networks in identifying BRCA genes. AB - BACKGROUND: Identification of driver genes related to certain types of cancer is an important research topic. Several systems biology approaches have been suggested, in particular for the identification of breast cancer (BRCA) related genes. Such approaches usually rely on differential gene expression and/or mutational landscape data. In some cases interaction network data is also integrated to identify cancer-related modules computationally. RESULTS: We provide a framework for the comparative graph-theoretical analysis of networks integrating the relevant gene expression, mutations, and potein-protein interaction network data. The comparisons involve a graph-theoretical analysis of normal and tumor network pairs across all instances of a given set of breast cancer samples. The network measures under consideration are based on appropriate formulations of various centrality measures: betweenness, clustering coefficients, degree centrality, random walk distances, graph-theoretical distances, and Jaccard index centrality. CONCLUSIONS: Among all the studied centrality-based graph-theoretical properties, we show that a betweenness-based measure differentiates BRCA genes across all normal versus tumor network pairs, than the rest of the popular centrality-based measures. The AUROC and AUPR values of the gene lists ordered with respect to the measures under study as compared to NCBI BioSystems pathway and the COSMIC database of cancer genes are the largest with the betweenness-based differentiation, followed by the measure based on degree centrality. In order to test the robustness of the suggested measures in prioritizing cancer genes, we further tested the two most promising measures, those based on betweenness and degree centralities, on randomly rewired networks. We show that both measures are quite resilient to noise in the input interaction network. We also compared the same measures against a state-of-the-art alternative disease gene prioritization method, MUFFFINN. We show that both our graph-theoretical measures outperform MUFFINN prioritizations in terms of ROC and precions/recall analysis. Finally, we filter the ordered list of the best measure, the betweenness-based differentiation, via a maximum-weight independent set formulation and investigate the top 50 genes in regards to literature verification. We show that almost all genes in the list are verified by the breast cancer literature and three genes are presented as novel genes that may potentialy be BRCA-related but missing in literature. PMID- 29166897 TI - Do effects of common case-mix adjusters on patient experiences vary across patient groups? AB - BACKGROUND: Many survey studies in health care adjust for demographic characteristics such as age, gender, educational attainment and general health when performing statistical analyses. Whether the effects of these demographic characteristics are consistent between patient groups remains to be determined. This is important as the rationale for adjustment is often that demographic sub groups differ in their so-called 'response tendency'. This rationale may be less convincing if the effects of response tendencies vary across patient groups. The present paper examines whether the impact of these characteristics on patients' global rating of care varies across patient groups. METHODS: Secondary analyses using multi-level regression models were performed on a dataset including 32 different patient groups and 145,578 observations. For each demographic variable, the 95% expected range of case-mix coefficients across patient groups is presented. In addition, we report whether the variance of coefficients for demographic variables across patient groups is significant. RESULTS: Overall, men, elderly, lower educated people and people in good health tend to give higher global ratings. However, these effects varied significantly across patient groups and included the possibility of no effect or an opposite effect in some patient groups. CONCLUSION: The response tendency attributed to demographic characteristics - such as older respondents being milder, or higher educated respondents being more critical - is not general or universal. As such, the mechanism linking demographic characteristics to survey results on patient experiences with quality of care is more complicated than a general response tendency. It is possible that the response tendency interacts with patient group, but it is also possible that other mechanisms are at play. PMID- 29166898 TI - Stakeholders perspectives on the key components of community-based interventions coordinating care in dementia: a qualitative systematic review. AB - BACKGROUND: Interventions aiming to coordinate services for the community-based dementia population vary in components, organisation and implementation. In this review we aimed to investigate the views of stakeholders on the key components of community-based interventions coordinating care in dementia. METHODS: We searched four databases from inception to June 2015; Medline, The Cochrane Library, EMBASE and PsycINFO, this was aided by a search of four grey literature databases, and backward and forward citation tracking of included papers. Title and abstract screening was followed by a full text screen by two independent reviewers, and quality was assessed using the CASP appraisal tool. We then conducted thematic synthesis on extracted data. RESULTS: A total of seven papers from five independent studies were included in the review, and encompassed the views of over 100 participants from three countries. Through thematic synthesis we identified 32 initial codes that were grouped into 5 second-order themes: (1) case manager had four associated codes and described preferences for the case manager personal and professional attributes, including a sound knowledge in dementia and availability of local services; (2) communication had five associated codes and emphasized the importance stakeholders placed on multichannel communication with service users, as well as between multidisciplinary teams and across organisations; (3) intervention had 11 associated codes which focused primarily on the practicalities of implementation such as the contact type and frequency between case managers and service users, and the importance of case manager training and service evaluation; (4) resources had five associated codes which outlined stakeholder views on the required resources for coordinating interventions and potential overlap with existing resources, as well as arising issues when available resources do not meet those required for successful implementation; and (5) support had seven associated codes that reflect the importance that was placed on the support network around the case manager and the investment of professionals involved directly in care as well as the wider professional network. CONCLUSION: The synthesis of relevant qualitative studies has shown how various stakeholder groups considered dementia care coordination interventions to be acceptable, useful and appropriate for dementia care, and have clear preferences for components, implementation methods and settings of these interventions. By incorporating stakeholders' perspectives and preferences when planning and developing coordinating interventions we may increase the likelihood of successful implementation and patient benefits. PMID- 29166899 TI - Medical thoracoscopy for exudative pleural effusion: an eight-year experience from a country with a young population. AB - BACKGROUND: With the exception of areas with high prevalence of tuberculosis, medical thoracoscopy is becoming the diagnostic modality of choice for exudative pleural effusions. The aims of this study were to determine the diagnostic yield and safety of medical thoracoscopy for exudative pleural effusions and ascertain the etiology of such effusions in Qatar. METHODS: This is a retrospective descriptive study of 407 patients who underwent diagnostic medical thoracoscopy for exudative pleural effusions from January, 2008 till December, 2015 at the only tertiary referral center performing this procedure in Qatar. RESULTS: Tuberculosis was the most common etiology of exudative pleural effusions in Qatar accounting for 84.5% of all causes. Around 85% of patients were young males (mean age of 33 +/- 12.1 years). The diagnostic yield of medical thoracoscopy for tuberculous pleural effusion was 91.4%. Malignant pleural effusions accounted for 5.2% of cases. Minor bleeding occurred in 1.2% of cases with no procedure-related mortality observed. CONCLUSION: Medical thoracoscopy is a very safe procedure. Tuberculous pleuritis is by far the most common etiology of exudative pleural effusions in Qatar. Closed needle biopsy is a worth consideration as an initial safe, easy and low-cost diagnostic modality for exudative pleural effusions in this country. PMID- 29166900 TI - Association between borderline dysnatremia and mortality insight into a new data mining approach. AB - BACKGROUND: Even small variations of serum sodium concentration may be associated with mortality. Our objective was to confirm the impact of borderline dysnatremia for patients admitted to hospital on in-hospital mortality using real life care data from our electronic health record (EHR) and a phenome-wide association analysis (PheWAS). METHODS: Retrospective observational study based on patient data admitted to Hopital Europeen George Pompidou, between 01/01/2008 and 31/06/2014; including 45,834 patients with serum sodium determinations on admission. We analyzed the association between dysnatremia and in-hospital mortality, using a multivariate logistic regression model to adjust for classical potential confounders. We performed a PheWAS to identify new potential confounders. RESULTS: Hyponatremia and hypernatremia were recorded for 12.0% and 1.0% of hospital stays, respectively. Adjusted odds ratios (ORa) for severe, moderate and borderline hyponatremia were 3.44 (95% CI, 2.41-4.86), 2.48 (95% CI, 1.96-3.13) and 1.98 (95% CI, 1.73-2.28), respectively. ORa for severe, moderate and borderline hypernatremia were 4.07 (95% CI, 2.92-5.62), 4.42 (95% CI, 2.04 9.20) and 3.72 (95% CI, 1.53-8.45), respectively. Borderline hyponatremia (ORa = 1.57 95% CI, 1.35-1.81) and borderline hypernatremia (ORa = 3.47 95% CI, 2.43 4.90) were still associated with in-hospital mortality after adjustment for classical and new confounding factors identified through the PheWAS analysis. CONCLUSION: Borderline dysnatremia on admission are independently associated with a higher risk of in-hospital mortality. By using medical data automatically collected in EHR and a new data mining approach, we identified new potential confounding factors that were highly associated with both mortality and dysnatremia. PMID- 29166901 TI - Tracking dyspnea up to supplemental oxygen prescription among patients with pulmonary fibrosis. AB - BACKGROUND: Dyspnea is the hallmark symptom of pulmonary fibrosis. Supplemental oxygen (O2) is prescribed to many patients with pulmonary fibrosis in hopes of alleviating dyspnea and improving physical functioning. We used response data from the University of California San Diego Shortness of Breath Questionnaire (UCSD) which was administered monthly in the context of a longitudinal, observational study to plot a rich trajectory for dyspnea over time in patients with pulmonary fibrosis. We used other data from that study to identify clinical predictors of being prescribed O2 and to provide additional information for how UCSD scores could be used for clinical purposes. METHODS: We used linear mixed effects models and multivariate Cox proportional hazards to model change in dyspnea scores over time and to identify significant predictors of time-to-O2 prescription among a pool of clinically-meaningful candidate variables. In the longitudinal study, all decisions, including whether or not to prescribe O2, were made by subjects' treating physicians, not members of the research team. RESULTS: One-hundred ninety-four subjects with pulmonary fibrosis completed more than one UCSD or were prescribed O2 at some point during the follow-up period (N = 43). Twenty-eight of the 43 had analyzable, longitudinal data and contribute data to the longitudinal UCSD analyses. All 43 were included in the time-to-O2 prescription analyses. Subjects prescribed O2 had more severe dyspnea at enrollment (38.4 +/- 19.6 vs. 22.6 +/- 18.7, p < 0.0001) and a steeper increase in UCSD scores over time (slope = 1.18 +/- 0.53 vs. 0.24 +/- 0.09 points per month, p = 0.02) than subjects not prescribed O2. Controlling for baseline UCSD score and FVC%, subjects with a clinical summary diagnosis of idiopathic pulmonary fibrosis (IPF) were far more likely to be prescribed O2 than subjects with other forms of pulmonary fibrosis (hazard ratio = 4.85, (2.19, 10.74), p < 0.0001). CONCLUSIONS: Baseline dyspnea and rise in dyspnea over time predict timing of O2 prescription. Accounting for disease severity, patients with IPF are more likely than patients with other forms of pulmonary fibrosis to be prescribed O2. UCSD scores provide clinically useful information; frequent administration could yield timely data on changes in disease status in patients with pulmonary fibrosis. TRIAL REGISTRATION: The longitudinal study is registered on ClinicalTrials.gov ( NCT01961362 ). Registered October 9, 2013. PMID- 29166902 TI - A national stakeholder consensus study of challenges and priorities for clinical learning environments in postgraduate medical education. AB - BACKGROUND: High quality clinical learning environments (CLE) are critical to postgraduate medical education (PGME). The understaffed and overcrowded environments in which many residents work present a significant challenge to learning. The purpose of this study was to develop a national expert group consensus amongst stakeholders in PGME to; (i) identify important barriers and facilitators of learning in CLEs and (ii) indicate priority areas for improvement. Our objective was to provide information to focus efforts to provide high quality CLEs. METHODS: Group Concept Mapping (GCM) is an integrated mixed methods approach to generating expert group consensus. A multi-disciplinary group of experts were invited to participate in the GCM process via an online platform. Multi-dimensional scaling and hierarchical cluster analysis were used to analyse participant inputs in regard to barriers, facilitators and priorities. RESULTS: Participants identified facilitators and barriers in ten domains within clinical learning environments. Domains rated most important were those which related to residents' connection to and engagement with more senior doctors. Organisation and conditions of work and Time to learn with senior doctors during patient care were rated as the most difficult areas in which to make improvements. CONCLUSIONS: High quality PGME requires that residents engage and connect with senior doctors during patient care, and that they are valued and supported both as learners and service providers. Academic medicine and health service managers must work together to protect these elements of CLEs, which not only shape learning, but impact quality of care and patient safety. PMID- 29166903 TI - Evaluation of microRNA expression in plasma and skeletal muscle of thoroughbred racehorses in training. AB - BACKGROUND: Circulating miRNAs (ci-miRNAs) are endogenous, non-coding RNAs emerging as potential diagnostic biomarkers. Equine miRNAs have been previously identified including subsets of tissue-specific miRNAs. In order to investigate ci-miRNAs as diagnostic tools, normal patterns of expression for different scenarios including responses to exercise need to be identified. Human studies have demonstrated that many ci-miRNAs are up-regulated following exercise with changes in expression patterns in skeletal muscle. However, technical challenges such as haemolysis impact on accurate plasma ci-miRNA quantification, with haemolysis often occurring naturally in horses following moderate-to-intense exercise. The objectives of this study were to identify plasma ci-miRNA profiles and skeletal muscle miRNAs before and after exercise in Thoroughbreds (Tb), and to evaluate for the presence and effect of haemolysis on plasma ci-miRNA determination. Resting and post-exercise plasma ci-miRNA profiles and haemolysis were evaluated in twenty 3 year-old Tbs in sprint training. Resting and post exercise skeletal muscle miRNA abundance was evaluated in a second cohort of eleven 2 year-old Tbs just entering sprint training. Haemolysis was further quantified in resting blood samples from twelve Tbs in sprint training. A human plasma panel containing 179 miRNAs was used for profiling, with haemolysis assessed spectrophotometrically. Data was analysed using a paired Student's t test and Pearson's rank correlation. RESULTS: Plasma ci-miRNA data for 13/20 horses and all skeletal muscle miRNA data passed quality control. From plasma, 52/179 miRNAs were detected at both time-points. Haemolysis levels were greater than the threshold for accurate quantification of ci-miRNAs in 18/25 resting and all post-exercise plasma samples. Positive correlations (P < 0.05) between haemolysis and miRNA abundance were detected for all but 4 miRNAs, so exercise induced changes in plasma ci-miRNA expression could not be quantified. In skeletal muscle samples, 97/179 miRNAs were detected with 5 miRNAs (miR-21-5p, let-7d-3p, let-7d-5p, miR-30b-5p, miR-30e-5p) differentially expressed (DE, P < 0.05) between time-points. CONCLUSIONS: The degree of haemolysis needs to be determined prior to quantifying plasma ci-miRNA expression from horses in high intensity exercise training. Identification of DE miRNAs in skeletal muscle indicates modification of miRNA expression may contribute to adaptive training responses in Tbs. Using a human plasma panel likely limited detection of equine specific miRNAs. PMID- 29166904 TI - Behaviors in Advance Care Planning and ACtions Survey (BACPACS): development and validation part 1. AB - BACKGROUND: Although advance care planning (ACP) is fairly well understood, significant barriers to patient participation remain. As a result, tools to assess patient behaviour are required. The objective of this study was to improve the measurement of patient engagement in ACP by detecting existing survey design issues and establishing content and response process validity for a new survey entitled Behaviours in Advance Care Planning and ACtions Survey (BACPACS). METHODS: We based our new tool on that of an existing ACP engagement survey. Initial item reduction was carried out using behavior change theories by content and design experts to help reduce response burden and clarify questions. Thirty two patients with chronic diseases (cancer, heart failure or renal failure) were recruited for the think aloud cognitive interviewing with the new, shortened survey evaluating patient engagement with ACP. Of these, n = 27 had data eligible for analysis (n = 8 in round 1 and n = 19 in rounds 2 and 3). Interviews were audio-recorded and analyzed using the constant comparison method. Three reviewers independently listened to the interviews, summarized findings and discussed discrepancies until consensus was achieved. RESULTS: Item reduction from key content expert review and conversation analysis helped decrease number of items from 116 in the original ACP Engagement Survey to 24-38 in the new BACPACS depending on branching of responses. For the think aloud study, three rounds of interviews were needed until saturation for patient clarity was achieved. The understanding of ACP as a construct, survey response options, instructions and terminology pertaining to patient engagement in ACP warranted further clarification. CONCLUSIONS: Conversation analysis, content expert review and think aloud cognitive interviewing were useful in refining the new survey instrument entitled BACPACS. We found evidence for both content and response process validity for this new tool. PMID- 29166905 TI - Barriers to data quality resulting from the process of coding health information to administrative data: a qualitative study. AB - BACKGROUND: Administrative health data are increasingly used for research and surveillance to inform decision-making because of its large sample sizes, geographic coverage, comprehensivity, and possibility for longitudinal follow-up. Within Canadian provinces, individuals are assigned unique personal health numbers that allow for linkage of administrative health records in that jurisdiction. It is therefore necessary to ensure that these data are of high quality, and that chart information is accurately coded to meet this end. Our objective is to explore the potential barriers that exist for high quality data coding through qualitative inquiry into the roles and responsibilities of medical chart coders. METHODS: We conducted semi-structured interviews with 28 medical chart coders from Alberta, Canada. We used thematic analysis and open-coded each transcript to understand the process of administrative health data generation and identify barriers to its quality. RESULTS: The process of generating administrative health data is highly complex and involves a diverse workforce. As such, there are multiple points in this process that introduce challenges for high quality data. For coders, the main barriers to data quality occurred around chart documentation, variability in the interpretation of chart information, and high quota expectations. CONCLUSIONS: This study illustrates the complex nature of barriers to high quality coding, in the context of administrative data generation. The findings from this study may be of use to data users, researchers, and decision-makers who wish to better understand the limitations of their data or pursue interventions to improve data quality. PMID- 29166906 TI - Anaphylaxis in an emergency care setting: a one year prospective study in children and adults. AB - BACKGROUND: Current data on anaphylaxis is based on retrospective and register based studies. The objective of this study was to describe the epidemiology of anaphylaxis in a 1 year prospective study at the emergency care setting, Odense University Hospital, Denmark (2013-2014). METHODS: Prospective study at the emergency care setting, Odense University Hospital, Denmark (2013-2014). To identify anaphylaxis cases, records from all patients with clinical suspicion on anaphylaxis or a related diagnosis according to the International Classification of Diseases 10 and from patients treated at the emergency care setting or at prehospital level with adrenaline, antihistamines or glucocorticoids were reviewed daily. The identified cases were referred to the Allergy Center, where a standardized interview regarding the anaphylactic reaction was conducted. International guidelines were applied for the assessment of anaphylaxis and its pharmacological treatment. Severity of the anaphylactic reaction was evaluated according to Sampson's severity score. RESULTS: We identified 180 anaphylactic patients. Anaphylaxis represented 0.3%-0.4% of all contacts in the emergency care setting with an incidence rate of 26.8 cases per 100,000 person years (95% CI: 14.3-45.8) in children and 40.4 cases per 100,000 person years (95% CI: 32.8 49.3) in adults. Moderate to severe anaphylaxis was registered in 96% of the cases. Skin (96%) and respiratory (79%) symptoms were the most frequent registered, but 7% of cases in adults occurred without skin manifestations. The most common elicitor in children was food (61%), while drugs (48%) and venom (24%) were the main suspected elicitors in adults. Adrenaline was administered in 25% of the cases and it was significantly less administered than glucocorticoids (83%) and antihistamines (91%). The mortality rate during our study period was 0.3 cases per 100,000 person years. DISCUSSION: This is one of the first prospective studies on the epidemiology of anaphylaxis in children and adults, where the patients are identified not only based on diagnosis codes but also on history, symptoms and treatment and thereafter classified according to international diagnosis criteria for anaphylaxis. A limitation of this study is that only patients who gave consent to participate in the study were included. Furthermore, patients may have attended other hospitals during the study period. Therefore, the estimates are minimum figures. CONCLUSION: The prospective study design with a broad search profile yield a higher incidence than previously reported. Adrenaline was administered in a low proportion of the patients with moderate to severe anaphylaxis. Standardized diagnosis criteria among physicians treating anaphylaxis are needed. PMID- 29166907 TI - Quantifying seasonal and diel variation in Anopheline and Culex human biting rates in Southern Ecuador. AB - BACKGROUND: Quantifying mosquito biting rates for specific locations enables estimation of mosquito-borne disease risk, and can inform intervention efforts. Measuring biting itself is fraught with ethical concerns, so the landing rate of mosquitoes on humans is often used as a proxy measure. Southern coastal Ecuador was historically endemic for malaria (Plasmodium falciparum and Plasmodium vivax), although successful control efforts in the 2000s eliminated autochthonous transmission (since 2011). This study presents an analysis of data collected during the elimination period. METHODS: Human landing catch (HLC) data for three mosquito taxa: two malaria vectors, Anopheles albimanus and Anopheles punctimacula, and grouped Culex spp. were examined for this study. These data were collected by the National Vector Control Service of the Ministry of Health over a 5-year time span (2007-2012) in five cities in southern coastal Ecuador, at multiple households, in all months of the year, during dusk-dawn (18:00-6:00) hours, often at both indoor and outdoor locations. Hurdle models were used to determine if biting activity was fundamentally different for the three taxa, and to identify spatial and temporal factors influencing bite rate. Due to the many different approaches to studying and quantifying bite rates in the literature, a glossary of terms was created, to facilitate comparative studies in the future. RESULTS: Biting trends varied significantly with species and time. All taxa exhibited exophagic feeding behavior, and outdoor locations increased both the odds and incidence of bites across taxa. Anopheles albimanus was most frequently observed biting, with an average of 4.7 bites/h. The highest and lowest respective months for significant biting activity were March and July for An. albimanus, July and August for An. punctimacula, and February and July for Culex spp. CONCLUSIONS: Fine-scale differences in endophagy and exophagy, and temporal differences among months and hours exist in biting patterns among mosquito taxa in southern coastal Ecuador. This analysis provides detailed information for targeting vector control activities, and household level vector prevention strategies. These data were collected as part of routine vector surveillance conducted by the Ministry of Health, and such data have not been collected since. Reinstating such surveillance measures would provide important information to aid in preventing malaria re-emergence. PMID- 29166908 TI - Mathematical models for predicting human mobility in the context of infectious disease spread: introducing the impedance model. AB - BACKGROUND: Mathematical models of human mobility have demonstrated a great potential for infectious disease epidemiology in contexts of data scarcity. While the commonly used gravity model involves parameter tuning and is thus difficult to implement without reference data, the more recent radiation model based on population densities is parameter-free, but biased. In this study we introduce the new impedance model, by analogy with electricity. Previous research has compared models on the basis of a few specific available spatial patterns. In this study, we use a systematic simulation-based approach to assess the performances. METHODS: Five hundred spatial patterns were generated using various area sizes and location coordinates. Model performances were evaluated based on these patterns. For simulated data, comparison measures were average root mean square error (aRMSE) and bias criteria. Modeling of the 2010 Haiti cholera epidemic with a basic susceptible-infected-recovered (SIR) framework allowed an empirical evaluation through assessing the goodness-of-fit of the observed epidemic curve. RESULTS: The new, parameter-free impedance model outperformed previous models on simulated data according to average aRMSE and bias criteria. The impedance model achieved better performances with heterogeneous population densities and small destination populations. As a proof of concept, the basic compartmental SIR framework was used to confirm the results obtained with the impedance model in predicting the spread of cholera in Haiti in 2010. CONCLUSIONS: The proposed new impedance model provides accurate estimations of human mobility, especially when the population distribution is highly heterogeneous. This model can therefore help to achieve more accurate predictions of disease spread in the context of an epidemic. PMID- 29166909 TI - Multiscale positive feedbacks contribute to unidirectional gastric disease progression induced by helicobacter pylori infection. AB - BACKGROUND: Helicobacter Pylori (HP) is the most common risk factor for gastric cancer. Nearly half the world's population is infected with HP, but only a small percentage of those develop significant pathology. The bacteria itself does not directly cause cancer; rather it promotes an environment that is conducive to tumor formation. Upon infection, HP induces transcriptional changes in the host, leading to enhanced proliferation and host immune response. In addition, HP causes direct damage to gastric epithelial cells. RESULTS: We present a multiscale mechanistic model of HP induced changes. The model includes four modules representing the host transcriptional changes in response to infection, gastric atrophy, the Hedgehog pathway response, and the restriction point that controls cell cycle. This model was able to recapture a number of literature reported observations and was used as an "in silico" representation of the biological system for further analysis. Dynamical analysis of the model revealed that HP might induce the activation of multiple interplayed positive feedbacks, which in turn might result in a "ratchet ladder" system that promotes a unidirectional progression of gastric disease. CONCLUSIONS: The current multiscale model is able to recapitulate the observed experimental features of HP host interactions and provides dynamic insights on the epidemiologically observed heterogeneity in disease progression. This model provides a solid framework that can be further expanded and validated to include additional experimental evidence, to understand the complex multi-pathway interactions characterizing HP infection, and to design novel treatment protocols for HP induced diseases. PMID- 29166910 TI - Prevalence and genetic diversity analysis of human coronaviruses among cross border children. AB - BACKGROUND: More than a decade after the outbreak of human coronaviruses (HCoVs) SARS in Guangdong province and Hong Kong SAR of China in 2002, there is still no reoccurrence, but the evolution and recombination of the coronaviruses in this region are still unknown. Therefore, surveillance on the prevalence and the virus variation of HCoVs circulation in this region is conducted. METHODS: A total of 3298 nasopharyngeal swabs samples were collected from cross-border children (<6 years, crossing border between Southern China and Hong Kong SAR) showing symptoms of respiratory tract infection, such as fever (body temperature > 37.5 degrees C), from 2014 May to 2015 Dec. Viral nucleic acids were analyzed and sequenced to study the prevalence and genetic diversity of the four human coronaviruses. The statistical significance of the data was evaluated with Fisher chi-square test. RESULTS: 78 (2.37%; 95%CI 1.8-2.8%) out of 3298 nasopharyngeal swabs specimens were found to be positive for OC43 (36;1.09%), HKU1 (34; 1.03%), NL63 (6; 0.18%) and 229E (2;0.01%). None of SARS or MERS was detected. The HCoVs predominant circulating season was in transition of winter to spring, especially January and February and NL63 detected only in summer and fall. Complex population with an abundant genetic diversity of coronaviruses was circulating and they shared homology with the published strains (99-100%). Besides, phylogenetic evolutionary analysis indicated that OC43 coronaviruses were clustered into three clades (B,D,E), HKU1 clustered into two clades(A,B) and NL63 clustered into two clades(A,B). Moreover, several novel mutations including nucleotides substitution and the insertion of spike of the glycoprotein on the viral surface were discovered. CONCLUSIONS: The detection rate and epidemic trend of coronaviruses were stable and no obvious fluctuations were found. The detected coronaviruses shared a conserved gene sequences in S and RdRp. However, mutants of the epidemic strains were detected, suggesting continuous monitoring of the human coronaviruses is in need among cross-border children, who are more likely to get infected and transmit the viruses across the border easily, in addition to the general public. PMID- 29166911 TI - Effective strategies for scaling up evidence-based practices in primary care: a systematic review. AB - BACKGROUND: While an extensive array of existing evidence-based practices (EBPs) have the potential to improve patient outcomes, little is known about how to implement EBPs on a larger scale. Therefore, we sought to identify effective strategies for scaling up EBPs in primary care. METHODS: We conducted a systematic review with the following inclusion criteria: (i) study design: randomized and non-randomized controlled trials, before-and-after (with/without control), and interrupted time series; (ii) participants: primary care-related units (e.g., clinical sites, patients); (iii) intervention: any strategy used to scale up an EBP; (iv) comparator: no restrictions; and (v) outcomes: no restrictions. We searched MEDLINE, Embase, PsycINFO, Web of Science, CINAHL, and the Cochrane Library from database inception to August 2016 and consulted clinical trial registries and gray literature. Two reviewers independently selected eligible studies, then extracted and analyzed data following the Cochrane methodology. We extracted components of scaling-up strategies and classified them into five categories: infrastructure, policy/regulation, financial, human resources-related, and patient involvement. We extracted scaling up process outcomes, such as coverage, and provider/patient outcomes. We validated data extraction with study authors. RESULTS: We included 14 studies. They were published since 2003 and primarily conducted in low-/middle-income countries (n = 11). Most were funded by governmental organizations (n = 8). The clinical area most represented was infectious diseases (HIV, tuberculosis, and malaria, n = 8), followed by newborn/child care (n = 4), depression (n = 1), and preventing seniors' falls (n = 1). Study designs were mostly before-and-after (without control, n = 8). The most frequently targeted unit of scaling up was the clinical site (n = 11). The component of a scaling-up strategy most frequently mentioned was human resource-related (n = 12). All studies reported patient/provider outcomes. Three studies reported scaling-up coverage, but no study quantitatively reported achieving a coverage of 80% in combination with a favorable impact. CONCLUSIONS: We found few studies assessing strategies for scaling up EBPs in primary care settings. It is uncertain whether any strategies were effective as most studies focused more on patient/provider outcomes and less on scaling-up process outcomes. Minimal consensus on the metrics of scaling up are needed for assessing the scaling up of EBPs in primary care. TRIAL REGISTRATION: This review is registered as PROSPERO CRD42016041461 . PMID- 29166912 TI - Neurofilament distribution in the superior labrum and the long head of the biceps tendon. AB - BACKGROUND: The postoperative course after arthroscopic superior labrum anterior to posterior (SLAP) repair using suture anchors is accompanied by a prolonged period of pain, which might be caused by constriction of nerve fibres. The purpose was to histologically investigate the distribution of neurofilament in the superior labrum and the long head of the biceps tendon (LHBT), i.e. the location of type II SLAP lesions. METHODS: Ten LHBTs including the superior labrum were dissected from fresh human specimen and immunohistochemically stained against neurofilament (NF). All slides were scanned at high resolution and converted into tagged image file format, and regions of interest (ROIs) were defined as follows: ROI I-superior labrum anterior to the LHBT origin, ROI II-mid portion of the superior labrum at the origin of the LHBT, ROI III-superior labrum posterior to the LHBT origin and ROI IV-the most proximal part of the LHBT before its attachment to the superior labrum. The entire images were automatically segmented according to the defined ROIs and measured using a programmed algorithm specifically created for this purpose. The NF-positive cells were counted, and their total size and the area of other tissue were measured separately for the different ROIs. RESULTS: Distribution of NF-positive cells in absolute numbers revealed a clear but insignificantly higher amount in favour of ROI I, representing the superior labrum anterior to the LHBT origin. Setting ROI I at 100%, a significant difference could be seen compared to ROI III, representing the superior labrum posterior to the LHBT origin (ROI I vs. ROI III with a p value < 0.05). CONCLUSIONS: Summarizing, the density of neurofilament is inhomogeneously distributed throughout the superior labrum with the highest number of neurofilament in the anterior superior labrum. Thus, suture placement in type II SLAP repair could play an important role for the postoperative pain related outcome. PMID- 29166913 TI - Socioeconomic disadvantage, fetal environment and child development: linked Scottish administrative records based study. AB - BACKGROUND: Cognitive development in childhood is negatively affected by socioeconomic disadvantage. This study examined whether differences in fetal environment might mediate the association between family socioeconomic position and child development. METHODS: Data were linked from the Scottish Longitudinal Study, maternity inpatient records and the Child Health Surveillance Programme - Pre School for 32,238 children. The outcome variables were based on health visitor assessment of gross motor, hearing and language, vision and fine motor, and social development. Socioeconomic position was measured using parental social class and highest qualification attained. Random-effects logistic regression models were estimated to account for multiple reviews and familial clustering. Mediation analysis was conducted using the Karlson-Holm-Breen method. RESULTS: Hearing and language, vision and fine motor, and social development were associated with lower parental social class and lower parental educational qualifications after adjustment for fetal environment. Fetal environment partially mediated the estimated effect of having parents without educational qualifications for hearing and language (beta = 0.15; 95% confidence interval (CI) = 0.07, 0.23), vision and fine motor (beta = 0.19; CI = 0.10, 0.28) and social development (beta = 0.14; CI = 0.03 to 0.25). CONCLUSIONS: Socioeconomic position predicted hearing and language, vision and fine motor, and social development but not gross motor development. For children of parents without educational qualifications, fetal environment appears to contribute to a part of the socioeconomic gradient in child development abnormalities but post-natal environment appears to still explain the majority of the gradient and for other children most of it. PMID- 29166914 TI - COGNAT: a web server for comparative analysis of genomic neighborhoods. AB - BACKGROUND: In prokaryotic genomes, functionally coupled genes can be organized in conserved gene clusters enabling their coordinated regulation. Such clusters could contain one or several operons, which are groups of co-transcribed genes. Those genes that evolved from a common ancestral gene by speciation (i.e. orthologs) are expected to have similar genomic neighborhoods in different organisms, whereas those copies of the gene that are responsible for dissimilar functions (i.e. paralogs) could be found in dissimilar genomic contexts. Comparative analysis of genomic neighborhoods facilitates the prediction of co regulated genes and helps to discern different functions in large protein families. AIM: We intended, building on the attribution of gene sequences to the clusters of orthologous groups of proteins (COGs), to provide a method for visualization and comparative analysis of genomic neighborhoods of evolutionary related genes, as well as a respective web server. RESULTS: Here we introduce the COmparative Gene Neighborhoods Analysis Tool (COGNAT), a web server for comparative analysis of genomic neighborhoods. The tool is based on the COG database, as well as the Pfam protein families database. As an example, we show the utility of COGNAT in identifying a new type of membrane protein complex that is formed by paralog(s) of one of the membrane subunits of the NADH:quinone oxidoreductase of type 1 (COG1009) and a cytoplasmic protein of unknown function (COG3002).

PMID- 29166915 TI - Serum connective tissue growth factor is a highly discriminatory biomarker for the diagnosis of rheumatoid arthritis. AB - BACKGROUND: Our previous proteomic study indicated that connective tissue growth factor (CTGF) may be a potential biomarker for rheumatoid arthritis (RA) diagnosis. The aim was to assess the performance of CTGF as a biomarker of RA. METHOD: Serum and synovial fluid CTGF was detected using a direct high sensitivity sandwich ELISA kit. Serum CTGF levels were tested for discriminatory capacity and optimal assay cutoffs determined in a training cohort of 98 cases of RA with 103 healthy controls. The assay performance was then validated in a further cohort of 572 patients (with RA (n = 217), ankylosing spondylitis (n = 92), gout (n = 74), osteoarthritis (n = 52), systemic lupus erythematosus (n = 72), or primary Sjogren's syndrome (pSS) (n = 65)). RESULTS: Significant elevation of synovial fluid CTGF concentration was found in RA patients, demonstrating excellent diagnostic ability to predict RA (area under the curve (AUC) = 0.97). Similar results were found in serum CTGF detection. At the optimal cutoff value 88.66 pg/mL, the sensitivity, specificity, and the AUC was 0.86, 0.92, and 0.92, respectively, in the training cohort. Similar performance was observed in the validation cohort, with sensitivity, specificity, positive likelihood, and negative likelihood of 0.82, 0.91, 5.74, and 0.12, respectively. Stronger discriminatory capacity was seen with the combination of CTGF and anti citrullinated protein antibody (ACPA) (AUC = 0.96) than with either ACPA or rheumatoid factor (RF) alone (AUC = 0.80 or 0.79, respectively). The discriminatory performance of serum CTGF was consistent across all inflammatory conditions tested (AUC >0.92 in all cases), with the sole exception of pSS. Serum CTGF did not vary with symptom duration or disease activity. CONCLUSIONS: Serum CTGF is a promising diagnostic biomarker for RA, with performance in the current study better than either ACPA or RF. PMID- 29166916 TI - Process optimization for enhancing production of cis-4-hydroxy-L-proline by engineered Escherichia coli. AB - BACKGROUND: Understanding the bioprocess limitations is critical for the efficient design of biocatalysts to facilitate process feasibility and improve process economics. In this study, a proline hydroxylation process with recombinant Escherichia coli expressing L-proline cis-4-hydroxylase (SmP4H) was investigated. The factors that influencing the metabolism of microbial hosts and process economics were focused on for the optimization of cis-4-hydroxy-L-proline (CHOP) production. RESULTS: In recombinant E. coli, SmP4H synthesis limitation was observed. After the optimization of expression system, CHOP production was improved in accordance with the enhanced SmP4H synthesis. Furthermore, the effects of the regulation of proline uptake and metabolism on whole-cell catalytic activity were investigated. The improved CHOP production by repressing putA gene responsible for L-proline degradation or overexpressing L-proline transporter putP on CHOP production suggested the important role of substrate uptake and metabolism on the whole-cell biocatalyst efficiency. Through genetically modifying these factors, the biocatalyst activity was significantly improved, and CHOP production was increased by twofold. Meanwhile, to further improve process economics, a two-strain coupling whole-cell system was established to supply co-substrate (alpha-ketoglutarate, alpha-KG) with a cheaper chemical L-glutamate as a starting material, and 13.5 g/L of CHOP was successfully produced. CONCLUSIONS: In this study, SmP4H expression, and L proline uptake and degradation, were uncovered as the hurdles for microbial production of CHOP. Accordingly, the whole-cell biocatalysts were metabolically engineered for enhancing CHOP production. Meanwhile, a two-strain biotransformation system for CHOP biosynthesis was developed aiming at supplying alpha-KG more economically. Our work provided valuable insights into the design of recombinant microorganism to improve the biotransformation efficiency that catalyzed by Fe(II)/alpha-KG-dependent dioxygenase. PMID- 29166917 TI - Collaborative action for person-centred coordinated care (P3C): an approach to support the development of a comprehensive system-wide solution to fragmented care. AB - BACKGROUND: Fragmented care results in poor outcomes for individuals with complexity of need. Person-centred coordinated care (P3C) is perceived to be a potential solution, but an absence of accessible evidence and the lack of a scalable 'blue print' mean that services are 'experimenting' with new models of care with little guidance and support. This paper presents an approach to the implementation of P3C using collaborative action, providing examples of early developments across this programme of work, the core aim of which is to accelerate the spread and adoption of P3C in United Kingdom primary care settings. METHODS: Two centrally funded United Kingdom organisations (South West Collaboration for Leadership in Applied Health Research and Care and South West Academic Health Science Network) are leading this initiative to narrow the gap between research and practice in this urgent area of improvement through a programme of service change, evaluation and research. Multi-stakeholder engagement and co-design are core to the approach. A whole system measurement framework combines outcomes of importance to patients, practitioners and health organisations. Iterative and multi-level feedback helps to shape service change while collecting practice-based data to generate implementation knowledge for the delivery of P3C. The role of the research team is proving vital to support informed change and challenge organisational practice. The bidirectional flow of knowledge and evidence relies on the transitional positioning of researchers and research organisations. RESULTS: Extensive engagement and embedded researchers have led to strong collaborations across the region. Practice is beginning to show signs of change and data flow and exchange is taking place. However, working in this way is not without its challenges; progress has been slow in the development of a linked data set to allow us to assess impact innovations from a cost perspective. Trust is vital, takes time to establish and is dependent on the exchange of services and interactions. If collaborative action can foster P3C it will require sustained commitment from both research and practice. This approach is a radical departure from how policy, research and practice traditionally work, but one that we argue is now necessary to deal with the most complex health and social problems. PMID- 29166918 TI - Engineering Bacillus megaterium for production of functional intracellular materials. AB - BACKGROUND: Over the last 10-15 years, a technology has been developed to engineer bacterial poly(3-hydroxybutyrate) (PHB) inclusions as functionalized beads, for applications such as vaccines, diagnostics and enzyme immobilization. This has been achieved by translational fusion of foreign proteins to the PHB synthase (PhaC). The respective fusion protein mediates self-assembly of PHB inclusions displaying the desired protein function. So far, beads have mainly been produced in recombinant Escherichia coli, which is problematic for some applications as the lipopolysaccharides (LPS) co-purified with such inclusions are toxic to humans and animals. RESULTS: In this study, we have bioengineered the formation of functional PHB inclusions in the Gram-positive bacterium Bacillus megaterium, an LPS-free and established industrial production host. As B. megaterium is a natural PHB producer, the PHB-negative strain PHA05 was used to avoid any background PHB production. Plasmid-mediated T7 promoter-driven expression of the genes encoding beta-ketothiolase (phaA), acetoacetyl-CoA reductase (phaB) and PHB synthase (phaC) enabled PHB production in B. megaterium PHA05. To produce functionalized PHB inclusions, the N- and C-terminus of PhaC was fused to four and two IgG binding Z-domains from Staphylococcus aureus, respectively. The ZZ-domain PhaC fusion protein was strongly overproduced at the surface of the PHB inclusions and the corresponding isolated ZZ-domain displaying PHB beads were found to purify IgG with a binding capacity of 40-50 mg IgG/g beads. As B. megaterium has the ability to sporulate and respective endospores could co-purify with cellular inclusions, a sporulation negative production strain was generated by disrupting the spoIIE gene in PHA05. This strain did not produce spores when tested under sporulation inducing conditions and it was still able to synthesize ZZ-domain displaying PHB beads. CONCLUSIONS: This study provides proof of concept for the successful genetic engineering of B. megaterium as a host for the production of functionalized PHB beads. Disruption of the spoIIE gene rendered B. megaterium incapable of sporulation but particularly suitable for production of functionalized PHB beads. This sporulation-negative mutant represents an improved industrial production strain for biotechnological processes otherwise impaired by the possibility of endospore formation. PMID- 29166919 TI - Similar short-term clinical response to high-dose versus low-dose methotrexate in monotherapy and combination therapy in patients with rheumatoid arthritis. AB - BACKGROUND: Aiming at rapid decrease of disease activity, there has been a trend to start with higher doses of methotrexate (MTX) in patients newly diagnosed with rheumatoid arthritis (RA), both as monotherapy and in combination with other antirheumatic drugs. We aimed to study the relationship between clinical response and MTX dose as monotherapy or combination therapy in patients with early RA. METHODS: Disease-modifying anti-rheumatic drug (DMARD)-naive patients with early RA, from a large international observational database, the METEOR database, were selected if MTX was part of their initial treatment. Patients were divided into four groups: MTX monotherapy, MTX + convention synthetic (cs)DMARDs, MTX + glucocorticoids or MTX + biologic (b)DMARDs. MTX dose was dichotomized: low dose <=10 mg/week; high dose >=15 mg/week. Linear mixed model analyses for the Disease Activity Score (DAS), DAS in 28 joints (DAS28) and Health Assessment Questionnaire (HAQ) were performed in each medication group, with MTX dose and time as covariates. Outcomes were assessed from baseline until 3-6 months follow up. Associations were adjusted for potential confounding by indication using propensity score (PS) modelling. RESULTS: For patients starting MTX monotherapy (n = 523), MTX + csDMARDs (n = 266) or MTX + glucocorticoids (n = 615), the PS adjusted effects of MTX dose (high versus low) on the DAS, DAS28 and HAQ were small and not clinically meaningful. Patients starting MTX + bDMARDs were disregarded due to low numbers (n =11). CONCLUSIONS: In patients newly diagnosed with RA, no clinical benefit of high compared to low initial MTX doses was found for MTX monotherapy or for MTX combination therapy with csDMARDs or glucocorticoids. PMID- 29166920 TI - A 3D epithelial-mesenchymal co-culture model of human bronchial tissue recapitulates multiple features of airway tissue remodeling by TGF-beta1 treatment. AB - BACKGROUND: The collagen gel contraction assay measures gel size to assess the contraction of cells embedded in collagen gel matrices. Using the assay with lung fibroblasts is useful in studying the lung tissue remodeling process in wound healing and disease development. However, the involvement of bronchial epithelial cells in this process should also be investigated. METHODS: We applied a layer of mucociliary differentiated bronchial epithelial cells onto collagen gel matrices with lung fibroblasts. This co-culture model enables direct contact between epithelial and mesenchymal cells. We stimulated the culture with transforming growth factor (TGF) beta1 as an inducer of tissue remodeling for 21 days, and measured gel size, histological changes, and expression of factors related to extracellular matrix homeostasis. RESULTS: TGF-beta1 exerted a concentration dependent effect on collagen gel contraction and on contractile myofibroblasts in the mesenchymal collagen layer. TGF-beta1 also induced expression of the mesenchymal marker vimentin in the basal layer of the epithelium, suggesting the induction of epithelial-mesenchymal transition. In addition, the expression of various genes encoding extracellular matrix proteins was upregulated. Fibrotic tenascin-C accumulated in the sub-epithelial region of the co-culture model. CONCLUSION: Our findings indicate that TGF-beta1 can affect both epithelial and mesenchymal cells, and induce gel contraction and structural changes. Our novel in vitro co-culture model will be a useful tool for investigating the roles of epithelial cells, fibroblasts, and their interactions in the airway remodeling process. PMID- 29166921 TI - Identification of epidermal growth factor receptor-positive glioblastoma using lipid-encapsulated targeted superparamagnetic iron oxide nanoparticles in vitro. AB - BACKGROUND: Targeted superparamagnetic iron oxide (SPIO) nanoparticles have emerged as a promising biomarker detection tool for molecular magnetic resonance (MR) image diagnosis. To identify patients who could benefit from Epidermal growth factor receptor (EGFR)-targeted therapies, we introduce lipid-encapsulated SPIO nanoparticles and hypothesized that anti-EGFR antibody cetuximab conjugated of such nanoparticles can be used to identify EGFR-positive glioblastomas in non invasive T2 MR image assays. The newly introduced lipid-coated SPIOs, which imitate biological cell surface and thus inherited innate nonfouling property, were utilized to reduce nonspecific binding to off-targeted cells and prevent agglomeration that commonly occurs in nanoparticles. RESULTS: The synthesized targeted EGFR-antibody-conjugated SPIO (EGFR-SPIO) nanoparticles were characterized using dynamic light scattering, zeta potential assays, gel electrophoresis mobility shift assays, transmission electron microscopy (TEM) images, and cell line affinity assays, and the results showed that the conjugation was successful. The targeting efficiency of the synthesized EGFR-SPIO nanoparticles was confirmed through Prussian blue staining and TEM images by using glioblastoma cell lines with high or low EGFR expression levels. The EGFR SPIO nanoparticles preferentially targeted U-251 cells, which have high EGFR expression, and were internalized by cells in a prolonged incubation condition. Moreover, the T2 MR relaxation time of EGFR-SPIO nanoparticles could be used for successfully identifying glioblastoma cells with elevated EGFR expression in vitro and distinguishing U-251 cells from U-87MG cells, which have low EFGR expression. CONCLUSION: These findings reveal that the lipid-encapsulated EGFR SPIO nanoparticles can specifically target cells with elevated EGFR expression in the three tested human glioblastoma cell lines. The results of this study can be used for noninvasive molecular MR image diagnosis in the future. PMID- 29166922 TI - Herpes simplex type 1 pneumonitis and acute respiratory distress syndrome in a patient with chronic lymphatic leukemia: a case report. AB - BACKGROUND: Pulmonary pathogenicity of herpes simplex virus type 1 in patients in intensive care without classic immunosuppression as well as the necessity of antiviral treatment in the case of herpes simplex virus detection in respiratory specimens in these patients is controversial. We present a case of acute respiratory distress syndrome in a patient with stable chronic lymphatic leukemia not requiring treatment, in whom we diagnosed herpes simplex virus type 1 bronchopneumonitis based on herpes simplex virus type 1 detection in bronchoalveolar lavage fluid and clinical response to antiviral treatment. CASE PRESENTATION: A 72-year-old white man presented with symptoms of lower respiratory tract infection. His medical history was significant for chronic lymphatic leukemia, which had been stable without treatment, arterial hypertension, multiple squamous cell carcinomas of the scalp, and alcohol overuse. Community-acquired pneumonia was suspected and appropriate broad spectrum antibacterial treatment was initiated. Within a few hours, rapid respiratory deterioration led to cardiac arrest. He was successfully resuscitated, but developed acute respiratory distress syndrome. Furthermore, he remained febrile and inflammation markers remained elevated despite antibacterial treatment. Polymerase chain reaction from bronchoalveolar lavage fluid and viral culture from tracheobronchial secretions tested positive for herpes simplex virus type 1. We initiated antiviral treatment with acyclovir. Concomitantly we further escalated the antibacterial treatment, although no bacterial pathogen had been isolated at any point. Defervescence occurred rapidly and his C-reactive protein and leukocyte levels decreased. He was successfully weaned from mechanical ventilation, transferred to the ward, and eventually discharged to home. CONCLUSIONS: Herpes simplex virus should be considered a cause for lower respiratory tract infection in critically ill patients, especially in the setting of an underlying disease. PMID- 29166923 TI - Childhood Takayasu arteritis: disease course and response to therapy. AB - BACKGROUND: Takayasu arteritis (TAK) is a large vessel vasculitis that rarely affects children. Data on childhood TAK are scarce. The aim of this study was to analyze the presenting features, course and outcome of children with TAK, compare efficacy of treatment regimens and identify high-risk factors for adverse outcome. METHODS: A single-center cohort study of consecutive children fulfilling the EULAR/PRINTO/PReS criteria for childhood TAK between 1986 and 2015 was performed. Clinical phenotypes, laboratory markers, imaging features, disease course and treatment were documented. Disease activity was assessed using the Pediatric Vasculitis Disease Activity Score at each visit. OUTCOME: disease flare defined as new symptoms and/or increased inflammatory markers necessitating therapy escalation and/or new angiographic lesions, or death. ANALYSIS: logistic regression tested relevant variables for flare. Kaplan-Meier analyses compared treatment regimens. RESULTS: Twenty-seven children were included; 74% were female, median age at diagnosis was 12.4 years. Twenty-two (81%) children presented with active disease at diagnosis. Treatment regimens included corticosteroids alone (15%), corticosteroids plus methotrexate (37%), cyclophosphamide (19%), or a biologic agent (11%). Adverse outcomes were documented in 14/27 (52%) children: two (7%) died within 6 months of diagnosis, and 13 (48%) experienced disease flares. The 2-year flare-free survival was 80% with biologic treatments compared to 43% in non-biologic therapies (p = 0.03); at last follow-up, biologic therapies resulted in significantly higher rates of inactive disease (p = 0.02). No additional outcome predictor was identified. CONCLUSIONS: Childhood TAK carries a high disease burden; half of the children experienced flares and 7% died. Biologic therapies were associated with better control of disease activity. PMID- 29166924 TI - Experience with etanercept, tocilizumab and interleukin-1 inhibitors in systemic onset juvenile idiopathic arthritis patients from the BIKER registry. AB - BACKGROUND: Treatment of systemic onset juvenile idiopathic arthritis JIA (sJIA), although dramatically improved, remains a challenge. Experience from clinical practice will be presented using data from the German Biologics register (BiKeR) for evaluation of efficacy and safety of treatment with etanercept (ETA), tocilizumab (TOC) and the interleukin-1 inhibitors anakinra and canakinumab (IL 1i) in sJIA. METHODS: Patients with sJIA documented in the BIKeR register, who were exposed to ETA, TOC or IL-1i were identified. Baseline demographics, clinical characteristics and disease activity parameters have been documented. Efficacy was determined using the JIA-American College of Rheumatology (ACR) response criteria and the Juvenile Disease Activity Score 10 (JADAS10). An intention-to-treat analysis was performed and patients who discontinued due to inefficacy or intolerance were analysed as non-responders. Safety assessments were based on adverse events (AEs) reports. RESULTS: Since 2000, 245 sJIA patients (50.3% male) exposed to biologic agents have been identified: 143 patients treated with ETA, 71 with TOC and 60 with IL-1i (anakinra 38, canakinumab 22). All patients received systemic steroids for pre-treatment but less frequently with TOC and IL-1i than with ETA for concomitant treatment. At baseline, the ETA cohort had fewer systemic disease manifestations but more active joints. The JIA-ACR 30/50/70/90 response over a period of 24 months was reached more often in the IL-1i and TOC cohort than with ETA. ETA/TOC/IL1i JADAS remission (JADAS <=1) was reached in 20%/37%/52%, minimal disease activity (JADAS <=3.8 in 35%/61%/68% and ACR inactive disease in 24%/33%/56%). As compared to ETA, rates of AEs were significantly higher in the TOC cohort (risk ratio (RR) 5.3/patient-year; p < 0.0001) and serious AE were observed more frequently with TOC (RR 2.5; p < 0.5) and IL1i (2.9; p < 0.01). CONCLUSIONS: A large proportion of patients gained significant response to treatment especially with TOC or IL 1is. After 6 months on treatment, JADAS remission was reached by up to half of patients while up to two thirds reached JADAS minimal disease activity. ETA has been used in the past but it is clearly less effective and its use in systemic JIA has markedly decreased in Germany. PMID- 29166925 TI - The effects of chemoradiotherapy on recurrence and survival in locally advanced rectal cancers with curative total mesorectal excision: a prospective, nonrandomized study. AB - BACKGROUND: There are only two prospective, randomized studies comparing preoperative long-term chemoradiotherapy and postoperative chemoradiotherapy in locally advanced rectal cancer (LARC); however, conflicting results in terms of locoregional recurrence (LR) and survival rates have been reported. This prospective study aims to compare the effects of preoperative versus postoperative chemoradiotherapy on recurrence and survival rates in LARC patients. METHODS: From January 2003 to January 2016, a total of 336 eligible patients who were clinically diagnosed with LARC (T3-T4 tm or node-positive disease) were prospectively assigned into preoperative chemoradiotherapy (n = 177) and postoperative chemoradiotherapy (n = 159) groups. The preoperative treatment consisted of 50.4 Gy total dose of radiotherapy (delivered in fractions of 1.8 Gy) and concomitant two cycles chemotherapy of 5-fluorouracil and leucovorin. The patients in the preoperative group underwent curative total mesorectal excision (TME) following long-term chemoradiotherapy. Surgery was performed 8 (range 4-12) median weeks after the completion of the chemoradiotherapy. Similar protocol was administered to the postoperative group 4 weeks after the operation. Four cycles of adjuvant chemotherapy were added to the groups. The primary end points were locoregional recurrences and 5-year cancer specific, overall, and disease-free survivals. RESULTS: The mean follow-up period was 60.4 (range 12 to 168) months. Five-year cumulative incidence of locoregional recurrence (LR) was 7.4% in the preoperative group and 13.4% in the postoperative group (p = 0.021). Five-year cancer-specific survival (CSS) was 87.5% in the preoperative group and 80% in the postoperative group (p = 0.022). Overall survival (OS) was 79.8 versus 74.7% (p = 0.064), disease-free survival (DFS) was 75.2 versus 64.8% (p = 0.062), and severe late toxicity was 7.4 versus 13.2% (p = 0.002), respectively. The rate of patient compliance was higher in the preoperative group (p < 0.001). CONCLUSIONS: Preoperative chemoradiotherapy, as compared with postoperative chemoradiotherapy, significantly improved local control, patient compliance, CSS, and late toxicity and suggested a trend toward improved overall and disease-free survival. PMID- 29166926 TI - Protocol for a systematic review and meta-analysis on the clinical outcomes and cost of deep inferior epigastric perforator (DIEP) flap versus implants for breast reconstruction. AB - BACKGROUND: Mastectomy in the context of breast malignancy can have a profoundly negative impact on a woman's self-image, impairing personal, sexual and social relationships. The deep inferior epigastric perforator (DIEP) flap and implants are the two commonest reconstructive modalities that can potentially overcome this psychological trauma. The comparative data on clinical outcomes and costs of the two modalities is limited. We aim to synthesise the current evidence on DIEP versus implants to establish which is the superior technique for breast reconstruction, in terms of clinical outcomes and cost-effectiveness. METHODS: A comprehensive search will be undertaken of EMBASE, MEDLINE, Google Scholar, CENTRAL and Science citation index databases (1994 up to August 2017) to identify studies relevant for the review. Primary human studies evaluating clinical outcomes and cost of DIEP and implant-based reconstruction in context of breast malignancy will be included. Primary outcomes will be patient satisfaction and cosmetic outcome from patient-reported outcome measures (scores from validated tools, e.g. BREAST-Q tool), complications and cost-analysis. The secondary outcomes will be duration of surgery, number of surgical revisions, length of stay, availability of procedures and total number of clinic visits. DISCUSSION: This will be the first systematic review and meta-analysis in available literature comparing the clinical outcomes and cost-effectiveness of DIEP and implants for breast reconstruction. This review is expected to guide worldwide clinical practice for breast reconstruction. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42017072557 . PMID- 29166927 TI - Safety of transtympanic application of probiotics in a chinchilla animal model. AB - BACKGROUND: Chronic suppurative otitis media can be recalcitrant and difficult to treat, particularly with the increasing occurrence of antibiotic resistance. Lactobacillus plantarum is a probiotic that has been shown to decrease S. aureus and P. aeruginosa growth in wounds, making it a good candidate for the treatment of chronic suppurative otitis media. However, before it can be applied in the ear, its ototoxicity potential must be evaluated. METHODS: A prospective controlled trial was conducted in a chinchilla animal model at the Animal care research facilities of the Montreal Children's Hospital Research Institute to determine whether Lactobacillus plantarum is ototoxic when applied transtympanically. Ten chinchillas each had one ear randomly assigned to receive 109 CFU/mL of Lactobacillus plantarum solution, while the contralateral ear received saline. Auditory brainstem responses were measured bilaterally at 8, 20, 25 kHz before, at 7-10 days after application, and at 28 days after application of probiotic or saline. Facial nerve and vestibular function were assessed clinically. RESULTS: There were no statistically significant differences in hearing thresholds between control and experimental ears at 28 days after application. A difference of 11 dB was noted in the 25 kHz range at day 7-10, but resolved by day 28. No animals receiving probiotics developed vestibular nerve dysfunction. There was no histologic evidence of auditory hair cell damaged evidenced by scanning electron microscopy. CONCLUSION: Our study suggests that a single application of Lactobacillus plantarum at 109 CFU/mL does not cause ototoxicity in a chinchilla animal model. These preliminary safety evaluations and the pathogen inhibitory effects of L. plantarum demonstrated by previous studies present this probiotic as a candidate of interest for further investigation. PMID- 29166928 TI - Effects of long-term weekly iron and folic acid supplementation on lower genital tract infection - a double blind, randomised controlled trial in Burkina Faso. AB - BACKGROUND: Provision of routine iron supplements to prevent anaemia could increase the risk for lower genital tract infections as virulence of some pathogens depends on iron availability. This trial in Burkina Faso assessed whether weekly periconceptional iron supplementation increased the risk of lower genital tract infection in young non-pregnant and pregnant women. METHODS: Genital tract infections were assessed within a double blind, controlled, non inferiority trial of malaria risk among nulliparous women, randomised to receive either iron and folic acid or folic acid alone, weekly, under direct observation for 18 months. Women conceiving during this period entered the pregnancy cohort. End assessment (FIN) for women remaining non-pregnant was at 18 months. For the pregnancy cohort, end assessment was at the first scheduled antenatal visit (ANC1). Infection markers included Nugent scores for abnormal flora and bacterial vaginosis (BV), T. vaginalis PCR, vaginal microbiota, reported signs and symptoms, and antibiotic and anti-fungal prescriptions. Iron biomarkers were assessed at baseline, FIN and ANC1. Analysis compared outcomes by intention to treat and in iron replete/deficient categories. RESULTS: A total of 1954 women (mean 16.8 years) were followed and 478 (24.5%) became pregnant. Median supplement adherence was 79% (IQR 59-90%). Baseline BV prevalence was 12.3%. At FIN and ANC1 prevalence was 12.8% and 7.0%, respectively (P < 0.011). T. vaginalis prevalence was 4.9% at FIN and 12.9% at ANC1 (P < 0.001). BV and T. vaginalis prevalence and microbiota profiles did not differ at trial end-points. Iron-supplemented non-pregnant women received more antibiotic treatments for non genital infections (P = 0.014; mainly gastrointestinal infections (P = 0.005), anti-fungal treatments for genital infections (P = 0.014) and analgesics (P = 0.008). Weekly iron did not significantly reduce iron deficiency prevalence. At baseline, iron-deficient women were more likely to have normal vaginal flora (P = 0.016). CONCLUSIONS: Periconceptional weekly iron supplementation of young women did not increase the risk of lower genital tract infections but did increase general morbidity in the non-pregnant cohort. Unabsorbed gut iron due to malaria could induce enteric infections, accounting for the increased administration of antibiotics and antifungals in the iron-supplemented arm. This finding reinforces concerns about routine iron supplementation in highly malarious areas. TRIAL REGISTRATION: Trial registration number NCT01210040 . Registered with Clinicaltrials.gov on 27 September 2010. PMID- 29166929 TI - Prevalence of dietary supplement use and associated factors among female college students in Saudi Arabia. AB - BACKGROUND: The economic boom in Saudi Arabia indirectly prompted the use of dietary supplements in the last two decades. Our aim is to investigate the prevalence of dietary supplement use and its association with sociodemographic/lifestyle characteristics among Saudi female students. METHODS: In this cross-sectional study, 534 female participants (>=19 years of age) completed a self-administered questionnaire that include sociodemographic and lifestyle characteristics, perceived health status, dietary supplement use, general awareness, attitudes and behavior. RESULTS: In all participants, the prevalence of dietary supplement use was 76.6% (n = 409). High level of education (p = 0.002) and more physical activity (p = 0.008) exhibited a significant positive association with users than to non-users. The frequency showed that beta carotene (54.2%), chamomile (54.2%), and glucosamine (53.8%) were the most preferred diet supplements under the category "when needed". Cod liver oil (71.3%), omega 3 (68.3%), multi-vitamins (61.5%), ginseng (60%), and vitamin A (60%), were mostly used "from time to time". Multi-minerals (34.4%) were the preferred choice when it comes to daily use. The main reasons for supplement use were to "maintain healthy hair" and "injury and illness" (both 26.2%). About 38.4% were not aware and 30.3% disagree on differences taking supplements with or without consulting a medical professional. About 36.7% lack information about side effects while, 35.0% were unaware about any health effect of dietary supplements. CONCLUSION: The prevalence of dietary supplement use was high in Saudi female students and was significantly associated with sociodemographic and lifestyle factors. PMID- 29166930 TI - A prospective cohort study identifying risk factors for shoulder injuries in adolescent elite handball players: the Karolinska Handball Study (KHAST) study protocol. AB - BACKGROUND: Handball is a physical contact sport that includes frequent overhead throwing, and this combination leads to a high rate of shoulder injuries. Several factors have been associated with shoulder injuries in overhead athletes, but strong scientific evidence is lacking for most suggested risk factors. We therefore designed the Karolinska Handball Study (KHAST) with the aim to identify risk factors for shoulder injuries in adolescent male and female elite handball players studying at handball-profiled secondary schools in Sweden. Secondary objectives are to investigate whether shoulder function changes during the competition season and whether the physical profile of the players changes during their time in secondary school. METHODS: Players aged 15 to 19 years were included during the pre-season period of the 2014-2015 and the 2015-2016 seasons. At inclusion, players signed informed consent and filled in a questionnaire regarding playing position, playing level, previous handball experience, history of shoulder problems and athletic identity. Players also completed a detailed test battery at baseline evaluating the shoulder, neck and trunk. Players were then prospectively monitored weekly during the 2014-2015 and/or 2015-2016 competitive seasons regarding injuries and training/match workload. Results from the annual routine physical tests in the secondary school curriculum including bench press, deep squat, hand grip strength, clean lifts, squat jumps, counter movement jumps, <30 m sprints, chins, dips and Cooper's test will be collected until the end of the competitive season 2017-2018. The primary outcome is the incidence of shoulder injuries and shoulder problems. The secondary outcome is the prevalence of shoulder injuries and shoulder problems. DISCUSSION: Shoulder problems are frequent among handball players and a reduction of these injuries is therefore warranted. However, in order to introduce appropriate preventive measures, a detailed understanding of the underlying risk factors is needed. Our study has a high potential to identify important risk factors for shoulder injuries in adolescent elite handball players owing to a large study sample, a high response rate, data collection during consecutive seasons, and recording of potential confounding factors. PMID- 29166931 TI - Elevated LRRK2 autophosphorylation in brain-derived and peripheral exosomes in LRRK2 mutation carriers. AB - Missense mutations in the leucine-rich repeat kinase 2 (LRRK2) gene can cause late-onset Parkinson disease (PD). LRRK2 mutations increase LRRK2 kinase activities that may increase levels of LRRK2 autophosphorylation at serine 1292 (pS1292) and neurotoxicity in model systems. pS1292-LRRK2 protein can be packaged into exosomes and measured in biobanked urine. Herein we provide evidence that pS1292-LRRK2 protein is robustly expressed in cerebral spinal fluid (CSF) exosomes. In a novel cohort of Norwegian subjects with and without the G2019S LRRK2 mutation, with and without PD, we quantified levels of pS1292-LRRK2, total LRRK2, and other exosome proteins in urine from 132 subjects and in CSF from 82 subjects. CSF and urine were collected from the same morning clinic visit in 55 of the participants. We found that total LRRK2 protein concentration was similar in exosomes purified from either CSF or urine but the levels did not correlate. pS1292-LRRK2 levels were higher in urinary exosomes from male and female subjects with a LRRK2 mutation. Male LRRK2 mutation carriers without PD had intermediate pS1292-LRRK2 levels compared to male carriers with PD and controls. However, female LRRK2 mutation carriers without PD had the same pS1292-LRRK2 levels compared to female carriers with PD. pS1292-LRRK2 levels in CSF exosomes were near saturated in most subjects, ten-fold higher on average than pS1292-LRRK2 levels in urinary exosomes, irrespective of LRRK2 mutation status or PD diagnosis. These results provide insights into the effects of LRRK2 mutations in both the periphery and brain in a well-characterized clinical population and show that LRRK2 protein in brain exosomes may be much more active than in the periphery in most subjects. PMID- 29166932 TI - BAP1: case report and insight into a novel tumor suppressor. AB - BACKGROUND: BRCA1-Associated-Protein 1 (BAP1) is a dynamic tumor suppressor which, when mutated, has been associated with an increased risk of uveal melanoma, cutaneous melanoma, mesothelioma, and several other cancers. Germline BAP1 mutations have been extensively studied, where they have been found to cause hereditary cancer susceptibility. However, their sporadic counterparts, tumors that display a loss of BAP1 expression due to somatically arising mutations in the BAP1 gene, remain a poorly described entity. CASE PRESENTATION: Here we present the case of a 49-year-old female who presented with an asymptomatic dome shaped pink papule on the dorsal foot which was found on biopsy to be deficient in the BAP1 tumor suppressor. While the patient's family history did not suggest the presence of a familial cancer syndrome, germline genetic testing was performed and was negative. The patient underwent surgical excision of this sporadically appearing "BAPoma" by Mohs surgery. CONCLUSIONS: Given the relatively banal clinical appearance of these dome-shaped neoplasms, sporadic BAPomas may often be overlooked by clinicians and dermatologists. In addition to providing a representative case, here we also provide a synopsis of the current understanding of these neoplasms, both in terms of the histopathological features, as well as the molecular mechanisms underlying BAP1 function and its ability to prevent tumorigenesis. PMID- 29166933 TI - Correlation between facet tropism and lumbar degenerative disease: a retrospective analysis. AB - BACKGROUND: The aim of this study was to investigate the correlation between facet tropism and spinal degenerative diseases, such as degenerative lumbar spondylolisthesis, degenerative lumbar scoliosis, and lumbar disc herniation. METHODS: This study retrospectively analysed clinical data from the Department of Orthopaedics at The First Affiliated Hospital of Nanchang University. Ninety-two patients were diagnosed with lumbar spondylolisthesis, 64 patients with degenerative scoliosis, and 86 patients with lumbar disc herniation between 1 October 2014 and 1 October 2016. All patients were diagnosed using 3.0 T magnetic resonance imaging and underwent conservative or operative treatment. Facet tropism was defined as greater than a ten degree between the facet joint angles on both sides. RESULTS: For L3-L4 degenerative lumbar spondylolisthesis, one out of six cases had tropism compared to seven out of the 86 controls (p = 0.474). At the L4-L5 level, 17/50 cases had tropism compared to 4/42 cases in the control group (p = 0.013). At the L5-S1 level, 18/36 cases had tropism compared to 7/56 controls (p = 0.000). For degenerative lumbar scoliosis at the L1-L5 level, 83/256 cases had tropism as compared to 36/256 controls (p = 0.000). For L3-L4 lumbar disc herniation two out of eight cases had tropism compared to 14/78 controls (p = 0.625). At the L4-L5 level, 19/44 cases had tropism compared to four out of 42 controls (p = 0.001). At the L5-S1 level, 24/34 cases had tropism compared to 10/52 controls (p = 0.000). CONCLUSION: At the L4-5 and L5-S1 levels, facet tropism is associated with degenerative spondylolisthesis. In the degenerative lumbar scoliosis group, the number of case with facet tropism was significantly higher than that of the control group. Facet tropism was associated with lumbar disc herniation at the L4-5 and L5-S1 levels. Overall, in these three lumbar degenerative diseases, facet tropism is a common phenomenon. PMID- 29166934 TI - Arthroscopic patellar release for treatment of chronic symptomatic patellar tendinopathy: long-term outcome and influential factors in an athletic population. AB - BACKGROUND: Arthroscopic patellar release (APR) is utilized for minimally invasive surgical treatment of patellar tendinopathy. Evidence regarding long term success following the procedure is limited. Also, the influence of age and preoperative performance level, are incompletely understood. The aim of this study was to investigate whether APR translates into sustained pain relief over a long-term follow-up in athletes undergoing APR. Furthermore, we analyzed if age influences clinical and functional outcome measures in APR. METHODS: Between 1998 and 2010, 30 competitive and recreational athletes were treated with APR due to chronic refractory patellar tendinopathy. All data were analyzed retrospectively. Demographic data, such as age or level of performance prior to injury were extracted. Clinical as well as functional outcome measures (Swedish Victorian Institute of sport assessment for patella (VISA-P), the modified Blazina score, pain level following exercise, return to sports, and subjective knee function were assessed pre- and postoperatively. RESULTS: In total, 30 athletes were included in this study. At follow-up (8.8 +/- 2.82 years), clinical and functional outcome measures such as the mean Blazina score, VISA-P, VAS, and subjective knee function revealed significant improvement compared to before surgery (P < 0.001). The mean time required for return to sports was 4.03 +/- 3.18 months. After stratification by age, patients younger than 30 years of age yielded superior outcome in the mean Blazina score and pain level when compared to patients >=30 years (P = 0.0448). At 8 years of follow-up, patients yielded equivalent clinical and functional outcome scores compared to our previous investigation after four years following APR. CONCLUSION: In summary, APR can be regarded a successful, minimally invasive, and sustained surgical technique for the treatment of patella tendinopathy in athletes. Younger age at surgery may be associated with improved clinical and functional outcome following APR. PMID- 29166935 TI - Phytochemical and pharmacological evaluation of ethanolic extract of Lepisanthes rubiginosa L. leaves. AB - BACKGROUND: The current study was conducted to evaluate the antioxidant, analgesic, antihyperglycemic, neuropharmacological and antidiarrheal activities of ethanolic extract of Lepisanthes rubiginosa L. leaves in different experimental models. METHODS: Quantitative and qualitative analysis were done by TLC (thin layer chromatography) and DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging assay. Analgesic, antihyperglycemic and antidiarrheal activities were evaluated using acetic acid induced writhing in mice, oral glucose tolerance test and castor oil induced diarrhea, respectively. Neuropharmacological activity was investigated in mice using both Open Field and Hole Board methods. RESULTS: TLC analysis indicated the presence of antioxidant compounds in the extract we used. The extract showed IC50 value was 31.62 MUg/mL whereas the standard ascorbic acid showed 12.02 MUg/mL. In acetic acid induced writhing assay, the extract showed 46.07% and 58.43% writhing inhibition at the doses of 250 mg/kg and 500 mg/kg body weight, respectively whereas standard diclofenac-Na (25 mg/kg) showed 86.52% writhing inhibition. The plant extract showed significant (p < 0.05) antihyperglycemic activity on mice as compared to control groups. In neuropharmacological activity assay the experimental animal showed a noticeable decrease in locomotion by showing a decrease in number of square crossed and head dipping at both doses (250 mg/kg & 500 mg/kg). In antidiarrheal activity test, the plant extract at the doses of 250 mg/kg and 500 mg/kg showed percent inhibition of defecation 57.89 and 77.19 respectively, whereas standard loperamide (3 mg/kg) showed percent inhibition of defecation 88.59. CONCLUSION: The results demonstrated that the extract has potential antioxidant, analgesic, antihyperglycemic, neuropharmacological and antidiarrheal activity. PMID- 29166936 TI - Detection of pathogens by real-time PCR in adult patients with acute exacerbation of bronchial asthma. AB - BACKGROUND: Respiratory tract infection is a major cause of acute exacerbation of bronchial asthma (AEBA). Although recent findings suggest that common bacteria are causally associated with AEBA, a comprehensive epidemiologic analysis of infectious pathogens including common/atypical bacteria and viruses in AEBA has not been performed. Accordingly, we attempted to detect pathogens during AEBA by using real-time polymerase chain reaction (PCR) in comparison to conventional methods. METHODS: We prospectively enroled adult patients with AEBA from August 2012 to March 2014. Infectious pathogens collected in nasopharyngeal swab and sputum samples were examined in each patient by conventional methods and real time PCR, which can detect 6 bacterial and 11 viral pathogens. The causal association of these pathogens with AEBA severity and their frequency of monthly distribution were also examined. RESULTS: Among the 64 enroled patients, infectious pathogens were detected in 49 patients (76.6%) using real-time PCR and in 14 patients (21.9%) using conventional methods (p < 0.001). Real-time PCR detected bacteria in 29 patients (45.3%) and respiratory viruses in 28 patients (43.8%). Haemophilus influenzae was the most frequently detected microorganism (26.6%), followed by rhinovirus (15.6%). Influenza virus was the significant pathogen associated with severe AEBA. Moreover, AEBA occurred most frequently during November to January. CONCLUSIONS: Real-time PCR was more useful than conventional methods to detect infectious pathogens in patients with AEBA. Accurate detection of pathogens with real-time PCR may enable the selection of appropriate anti-bacterial/viral agents as a part of the treatment for AEBA. PMID- 29166937 TI - A putative Chondroprotective role for IL-1beta and MPO in herbal treatment of experimental osteoarthritis. AB - BACKGROUND: Herbal treatment may have a chondroprotective and therapeutic effect on Osteoarthritis (OA). We investigated the mechanism of action of ginger and curcumin rhizomes cultivated in Egypt in treatment of OA in rat model. METHODS: Thirty-five albino rats were intra-articularly injected with Monosodium Iodoacetate in the knee joint. Ginger and curcumin was orally administered at doses of 200 and 400 mg/kg (F200 and F400). Serum levels of cartilage oligomeric matrix protein (COMP), hyaluronic acid (HA), malondialdehyde (MDA), myeloperoxidase (MPO), Interleukin-1 beta (IL-1beta) and superoxide dismutase activity (SOD) were measured using ELISA. The composition of the herbal formula hydro-ethanolic extract was characterized using UPLC-ESI-MS. Histopathological changes in injected joints was examined using routine histopathology. Statistical analysis was performed using one-way ANOVA. RESULTS: Serum levels of COMP, HA, MPO, MDA, and IL-1beta were significantly decreased in F 200, F 400 and V groups when compared to OA group (P value <0.0001). On the other hand SOD levels were significantly elevated in treated groups compared to OA groups (P value <0.0001). CONCLUSIONS: The ginger/curcumin at 1:1 had chondroprotective effect via anti inflammatory and antioxidant effect in rat OA model. Further pharmacological and clinical studies are needed to evaluate this effect. PMID- 29166938 TI - A case of blunt thoracic aortic injury requiring ECMO for acute malperfusion before TEVAR. AB - BACKGROUND: Blunt thoracic aortic injury (BTAI) is associated with a high mortality rate and the paradigm of treating patients with BTAI currently favours thoracic endovascular aneurysm repair (TEVAR) if possible. In BTAI, lethal malperfusion caused by a pseudoaneurysm has rarely been reported. We present the first report of a successful case in which a pseudoaneurysm causing the infrequent occurrence of lethal malperfusion and subsequent acute severe ischaemia in the distal portion of the thoracic descending aorta was overcome by veno-arterial extracorporeal membrane oxygenation (VA ECMO) as a bridging therapy until the initiation of TEVAR. CASE PRESENTATION: An adult woman was transferred to our emergency room after injuries sustained by falling from height. Her vital signs were unstable on admission. CT examination revealed the multiple injuries: traumatic subarachnoid haemorrhage, severe unstable pelvic fracture, and a grade III injury of the thoracic aorta. We made the decision to perform TEVAR after external fixation and transcatheter arterial embolization (TAE) for the pelvic injury. During preparations for TEVAR, her lower limbs rapidly felt cold, and her blood lactate level and serum potassium rapidly increased. By the clinical data and ultrasonography and lower extremity Doppler, we diagnosed severe ischaemia in distal portion of the descending aorta caused by a pseudoaneurysm proximal to the descending thoracic aorta. Because we still had not prepared for TEVAR, we immediately started VA ECMO until TEVAR could begin. After the initiation of VA ECMO, her lactate and potassium levels could be controlled. Under VA ECMO support, she underwent TEVAR. After inpatient rehabilitation, she was discharged home without neurologic sequelae. CONCLUSIONS: VA ECMO could be an important, less-invasive treatment as a bridging therapy for acute severe malperfusion syndrome until TEVAR is initiated for BTAI. PMID- 29166939 TI - Acute cerebellitis in adults: a case report and review of the literature. AB - BACKGROUND: Acute cerebellitis is a rare disease with the majority of cases described in children. Little is known about the clinical characteristics and outcome in adults. CASE PRESENTATION: A 37-year-old Caucasian woman presented with headache, nausea, and photophobia, and was diagnosed as having a migraine attack. Two days later, she subsequently returned with aggravated headache, dysarthria and horizontal nystagmus. Magnetic resonance imaging (MRI) showed a swollen cerebellum and hydrocephalus and the patient was diagnosed with acute cerebellitis. Cerebrospinal fluid (CSF) examination showed an elevated leukocyte count and protein. Blood serology showed the presence of immunoglobulin M and immunoglobulin G for both Epstein-Barr virus and cytomegalovirus. The patient was treated with dexamethasone and discharged to a rehabilitation center, where she fully recovered. We searched the literature for adult cases of acute cerebellitis. Including our patient, we identified 35 patients with a median age of 36 years. The etiology was unknown in 34% of cases. The most common clinical presentation consisted of headache, nausea/vomiting and ataxia. Six patients presented with only headache and nausea and subsequently returned with cerebellar signs. In 9 cases, the cerebellitis was complicated by hydrocephalus. Half of the patients ended up with neurological sequelae, while follow-up MRI was abnormal in 71%. CONCLUSION: Acute cerebellitis in adults is a rare disorder which mainly presents with headache, nausea/vomiting and ataxia. To diagnose cerebellitis, imaging of the brain (preferably MRI) is required and CSF examination may be necessary to narrow the differential diagnosis. The treatment depends on the widely diverse etiology, and treatment with steroids is recommended in the case of cerebellar oedema and hydrocephalus. Neurosurgical intervention may be necessary to prevent brain herniation. PMID- 29166940 TI - Effects of urban coarse particles inhalation on oxidative and inflammatory parameters in the mouse lung and colon. AB - BACKGROUND: Air pollution is a recognized aggravating factor for pulmonary diseases and has notably deleterious effects on asthma, bronchitis and pneumonia. Recent studies suggest that air pollution may also cause adverse effects in the gastrointestinal tract. Accumulating experimental evidence shows that immune responses in the pulmonary and intestinal mucosae are closely interrelated, and that gut-lung crosstalk controls pathophysiological processes such as responses to cigarette smoke and influenza virus infection. Our first aim was to collect urban coarse particulate matter (PM) and to characterize them for elemental content, gastric bioaccessibility, and oxidative potential; our second aim was to determine the short-term effects of urban coarse PM inhalation on pulmonary and colonic mucosae in mice, and to test the hypothesis that the well-known antioxidant N-acetyl-L-cysteine (NAC) reverses the effects of PM inhalation. RESULTS: The collected PM had classical features of urban particles and possessed oxidative potential partly attributable to their metal fraction. Bioaccessibility study confirmed the high solubility of some metals at the gastric level. Male mice were exposed to urban coarse PM in a ventilated inhalation chamber for 15 days at a concentration relevant to episodic elevation peak of air pollution. Coarse PM inhalation induced systemic oxidative stress, recruited immune cells to the lung, and increased cytokine levels in the lung and colon. Concomitant oral administration of NAC reversed all the observed effects relative to the inhalation of coarse PM. CONCLUSIONS: Coarse PM-induced low-grade inflammation in the lung and colon is mediated by oxidative stress and deserves more investigation as potentiating factor for inflammatory diseases. PMID- 29166941 TI - Are there differences in treatment effects between labial and lingual fixed orthodontic appliances? A systematic review and meta-analysis. AB - BACKGROUND: An evaluation is made of possible differences in treatment effects between labial and lingual fixed appliances. METHODS: A comprehensive search was made of the PubMed-Medline, Cochrane Library and LILACS databases, with an additional manual search covering the period up until April 2017. There were no restrictions in terms of year of publication or language. Agreement between the authors was quantified by the Cohen kappa statistic. A random-effect model was applied to calculate weighted mean differences with 95% confidence intervals. RESULTS: A total of 249 patients corresponding to four eligible studies were included in the systematic review. Among the six angles and distances entered in the meta-analysis, a tendency was observed in lingual appliances to increase the interincisal angle (95% CI -0.80-8.99; p = 0.101) and reduce the angle between the major axis of upper central incisor and the sellar-nasion plane - though statistical significance was not reached (95% CI -5.75-0.32; p = 0.079). CONCLUSION: The results obtained indicate that treatment with lingual appliances favors incisor tipping by exerting lingual crown torque, but there are no differences in cephalometric values between labial and lingual fixed appliances. Because of the small number of included studies, the results of this meta analysis should be interpreted with caution. Future research should focus on the generation of a consensus document allowing selection of the type of orthodontic approach not only conditioned to the esthetic requirements of the patient but also considering the characteristics of the malocclusion. On the other hand, standardized international guidelines are lacking; the measurements of angles and distances therefore have to be unified with a view to future investigations. PMID- 29166942 TI - Postoperative radiotherapy with or without concurrent chemotherapy for oral squamous cell carcinoma in patients with three or more minor risk factors: a propensity score matching analysis. AB - BACKGROUND: To investigate the advantage of concurrent chemotherapy with postoperative radiotherapy (RT) of oral squamous cell carcinoma (OSCC) in patients with three or more minor risk factors. METHODS: Minor risk factors included pT4 disease, pN1 disease, margin <= 4 mm, poor differentiation, perineural invasion, vessel or lymphatic invasion, and tumor invasion depth >= 11 mm. Surgery was the primary treatment, followed by RT or concurrent chemoradiation (CCRT). After propensity score matching, 34 patients in each treatment group were selected for comparison. RESULTS: The median follow-up for living patients was 86.4 months (range: 47-189 months). The 5-year overall survival of the RT and CCRT groups was 35.3% and 67.2% (p = 0.018), respectively. The 5-year recurrence-free survival of the RT group and CCRT group was 42.6% and 75.4% (p < 0.01). CONCLUSION: Postoperative CCRT for patients with three or more minor risk factors increased recurrence-free and overall survival.

PMID- 29166944 TI - Targeting of vascular adhesion protein-1 by positron emission tomography visualizes sites of inflammation in Borrelia burgdorferi-infected mice. AB - BACKGROUND: In the present study, we sought to evaluate the feasibility of targeting vascular adhesion protein-1 (VAP-1) by positron emission tomography (PET) for the longitudinal quantitative assessment of Borrelia burgdorferi infection-induced inflammation in mice. METHODS: Mice with B. burgdorferi infection-induced arthritis were studied. During a 7-week follow-up period, the progression of arthritis was monitored weekly with 68Ga-DOTA-Siglec-9 PET/computed tomography (CT) and measurement of tibiotarsal joint swellings. A subgroup of infected mice was treated with ceftriaxone. Finally, histopathological assessment of joint inflammation was performed and VAP-1 expression in joints were determined. RESULTS: Explicit joint swelling and 68Ga DOTA-Siglec-9 uptake could be demonstrated in the affected joints from B. burgdorferi-infected mice. By contrast, no obvious accumulation of 68Ga-DOTA Siglec-9 was detected in joints of uninfected mice. The maximum swelling and highest uptake in the affected joints were observed 4 weeks after the infection. 68Ga-DOTA-Siglec-9 uptake in joints correlated with joint swelling (P < 0.0001) and histopathological scoring of inflammation (P = 0.020). Despite short-term antibiotic treatment, the arthritis persisted, and the PET signal remained as high as in nontreated mice. Immunohistochemistry revealed strong-to-moderate expression of VAP-1 in the synovium of B. burgdorferi-infected mice, while only weak expression of VAP-1 was detected in uninfected mice. CONCLUSIONS: The present study showed that 68Ga-DOTA-Siglec-9 can detect B. burgdorferi infection induced arthritis in mice. Furthermore, longitudinal PET/CT imaging allowed monitoring of arthritis development over time. PMID- 29166946 TI - Noise exposure while commuting in Toronto - a study of personal and public transportation in Toronto. AB - BACKGROUND: With an increasing proportion of the population living in cities, mass transportation has been rapidly expanding to facilitate the demand, yet there is a concern that mass transit has the potential to result in excessive exposure to noise, and subsequently noise-induced hearing loss. METHODS: Noise dosimetry was used to measure time-integrated noise levels in a representative sample of the Toronto Mass Transit system (subway, streetcar, and buses) both aboard moving transit vehicles and on boarding platforms from April - August 2016. 210 measurements were conducted with multiple measurements approximating 2 min on platforms, 4 min within a vehicle in motion, and 10 min while in a car, on a bike or on foot. Descriptive statistics for each type of transportation, and measurement location (platform vs. vehicle) was computed, with measurement locations compared using 1-way analysis of variance. RESULTS: On average, there are 1.69 million riders per day, who are serviced by 69 subway stations, and 154 streetcar or subway routes. Average noise level was greater in the subway and bus than in the streetcar (79.8 +/- 4.0 dBA, 78.1 +/- 4.9 dBA, vs 71.5 +/-1.8 dBA, p < 0.0001). Furthermore, average noise measured on subway platforms were higher than within vehicles (80.9 +/- 3.9 dBA vs 76.8 +/- 2.6 dBA, p < 0.0001). Peak noise exposures on subway, bus and streetcar routes had an average of 109.8 +/- 4.9 dBA and range of 90.4-123.4 dBA, 112.3 +/- 6.0 dBA and 89.4-128.1 dBA, and 108.6 +/- 8.1 dBA and 103.5-125.2 dBA respectively. Peak noise exposures exceeded 115 dBA on 19.9%, 85.0%, and 20.0% of measurements in the subway, bus and streetcar respectively. CONCLUSIONS: Although the mean average noise levels on the Toronto transit system are within the recommended level of safe noise exposure, cumulative intermittent bursts of impulse noise (peak noise exposures) particularly on bus routes have the potential to place individuals at risk for noise induced hearing loss. PMID- 29166945 TI - Predictive factors of acute skin reactions to carbon ion radiotherapy for the treatment of malignant bone and soft tissue tumors. AB - BACKGROUND: The skin is considered a critical organ at risk in carbon ion radiotherapy (CIRT) for locally advanced malignant bone and soft tissue tumors (MBSTs). The predictive factors for acute skin reactions after CIRT have not been investigated. The present study aimed to identify these factors and evaluate the correlation between the severity of acute skin reactions and skin dose parameters. METHODS: CIRT with total doses of 64.0-70.4 Gy (relative biological effectiveness [RBE]) was administered to 22 patients with MBSTs. The skin-tumor distance (STD), maximum skin total dose (Dmax), and area of the skin receiving a total dose of X Gy (RBE) were evaluated. RESULTS: All patients developed acute skin reactions after CIRT, including Grades 1 and 2 dermatitis in 15 (71%) and 6 (29%) patients, respectively. There was a significant difference in the STD between the two groups (P = 0.007), and the cut-off value of STD for predicting Grade 2 acute skin reactions was 11 mm. There was a significant difference in Dmax between the groups (P < 0.001), and the cut-off value of Dmax for predicting Grade 2 acute skin reactions was 52 Gy (RBE). Significant differences between the two groups were observed in terms of the area irradiated with 40 Gy (RBE) (S40), and the cut-off value of S40 for predicting Grade 2 acute skin reactions was 25 cm2. CONCLUSIONS: In acute skin reactions after CIRT for MBSTs, STD, Dmax, and S40 were found to be significant predictive factors for acute skin reactions.

AB - BACKGROUND: Evidence-based clinical practice is challenging in all fields, but poses special barriers in the field of rare diseases. The present paper summarises the main barriers faced by clinical research in rare diseases, and highlights opportunities for improvement. METHODS: Systematic literature searches without meta-analyses and internal European Clinical Research Infrastructure Network (ECRIN) communications during face-to-face meetings and telephone conferences from 2013 to 2017 within the context of the ECRIN Integrating Activity (ECRIN-IA) project. RESULTS: Barriers specific to rare diseases comprise the difficulty to recruit participants because of rarity, scattering of patients, limited knowledge on natural history of diseases, difficulties to achieve accurate diagnosis and identify patients in health information systems, and difficulties choosing clinically relevant outcomes. CONCLUSIONS: Evidence-based clinical practice for rare diseases should start by collecting clinical data in databases and registries; defining measurable patient-centred outcomes; and selecting appropriate study designs adapted to small study populations. Rare diseases constitute one of the most paradigmatic fields in which multi stakeholder engagement, especially from patients, is needed for success. Clinical research infrastructures and expertise networks offer opportunities for establishing evidence-based clinical practice within rare diseases. PMID- 29166949 TI - The 23-year tracking of blood lipids from adolescence to adulthood in Korea: the Kangwha study. AB - BACKGROUND: Several studies have examined tracking pattern of blood lipids level during long follow-up periods in Western countries. However, there have been few such studies in Asian populations. METHODS: The Kangwha Study is a community based prospective cohort study that started in 1986 on Kangwha Island, South Korea. A total of 432 participants (47% men) were enrolled in the study, during which serum total cholesterol, triglycerides, and high-density lipoprotein (HDL) cholesterol levels were measured for each participant at least once during adolescence (12-16 years of age) and again at least once during adulthood (25-35 years of age). The tracking patterns of the blood lipid levels were determined using Spearman correlation coefficients and tracking coefficients from generalized estimating equations. RESULTS: The Spearman correlation coefficients between lipid measurements ranged from 0.12 to 0.73 depending on the lipid profile and measurement time interval; all were significant (p < 0.05). The magnitude of the coefficients tended to decrease as the time interval increased. When adjusted for age, sex, body mass index, and blood pressure, the tracking coefficients were 0.58 (95% confidence interval [CI]: 0.54-0.63) for total cholesterol, 0.39 (95% CI: 0.31-0.48) for triglycerides, and 0.51 (95% CI: 0.47 0.56) for HDL cholesterol. In a subgroup analysis by sex, the tracking coefficients were higher for women than for men, except for HDL cholesterol. CONCLUSIONS: The tracking patterns of blood lipids from adolescence to adulthood were notable. This study supports the importance of measuring lipids during adolescence for identifying high-risk individuals.

This insular-like habitat system is known to support a mixture of sedentary and migratory bird species originating from different areas. However, little is known about the interactions between these birds and parasites. In this study, we investigated the diversity, prevalence and host specificity of avian haemosporidian parasites in southern Tunisian oases in two sedentary and common bird species, the laughing dove Spilopelia senegalensis and hybrid sparrow Passer domesticus * hispaniolensis, in six sites that differ regarding vegetation structure and distance to the coast. Two new Haemoproteus lineages, related to other Haemoproteus transmitted by biting midges, were detected in doves. With regard to sparrows, all detected parasites have previously been reported in other sparrow populations, except for one new Haemoproteus lineage. Our results also showed that densely vegetated sites were characterized by the higher prevalence of Plasmodium but a lower prevalence of Haemoproteus compared with less-vegetated sites. This is the first study aiming to explore avian parasites in the oasis habitat. Gathering data on a larger sample of oases with different sizes and isolation levels will be the next step to better understand factors shaping the transmission dynamics of avian parasites in such ecosystems. PMID- 29166950 TI - Global phylogenetic analysis of contemporary aleutian mink disease viruses (AMDVs). AB - BACKGROUND: Aleutian mink disease has major economic consequences on the mink farming industry worldwide, as it causes a disease that affects both the fur quality and the health and welfare of the mink. The virus causing this disease is a single-stranded DNA virus of the genus Amdoparvovirus belonging to the family of Parvoviridae. In Denmark, infection with AMDV has largely been restricted to a region in the northern part of the country since 2001, affecting only 5% of the total Danish mink farms. However, in 2015 outbreaks of AMDV were diagnosed in all parts of the country. Initial analyses revealed that the out breaks were caused by two different strains of AMDV that were significant different from the circulating Danish strains. To track the source of these outbreaks, a major investigation of global AMDV strains was initiated. METHODS: Samples from 13 different countries were collected and partial NS1 gene was sequenced and subjected to phylogenetic analyses. RESULTS: The analyses revealed that AMDV exhibited substantial genetic diversity. No clear country wise clustering was evident, but exchange of viruses between countries was revealed. One of the Danish outbreaks was caused by a strain of AMDV that closely resembled a strain originating from Sweden. In contrast, we did not identify any potential source for the other and more widespread outbreak strain. CONCLUSION: To the authors knowledge this is the first major global phylogenetic study of contemporary AMDV partial NS1 sequences. The study proved that partial NS1 sequencing can be used to distinguish virus strains belonging to major clusters. The partial NS1 sequencing can therefore be a helpful tool in combination with epidemiological data, in relation to outbreak tracking. However detailed information on farm to farm transmission requires full genome sequencing. PMID- 29166948 TI - Cause-specific mortality for 249 causes in Brazil and states during 1990-2015: a systematic analysis for the global burden of disease study 2015. AB - BACKGROUND: Reliable data on cause of death (COD) are fundamental for planning and resource allocation priorities. We used GBD 2015 estimates to examine levels and trends for the leading causes of death in Brazil from 1990 to 2015. METHODS: We describe the main analytical approaches focused on both overall and specific causes of death for Brazil and Brazilian states. RESULTS: There was an overall improvement in life expectancy at birth from 1990 to 2015, but with important heterogeneity among states. Reduced mortality due to diarrhea, lower respiratory infections, and other infectious diseases contributed the most for increasing life expectancy in most states from the North and Northeast regions. Reduced mortality due to cardiovascular diseases was the highest contributor in the South, Southeast, and Center West regions. However, among men, intentional injuries reduced life expectancy in 17 out of 27 states. Although age standardized rates due to ischemic heart disease (IHD) and cerebrovascular disease declined over time, these remained the leading CODs in the country and states. In contrast, leading causes of premature mortality changed substantially e.g., diarrheal diseases moved from 1st to 13th and then the 36th position in 1990, 2005, and 2015, respectively, while violence moved from 7th to 1st and to 2nd. Overall, the total age-standardized years of life lost (YLL) rate was reduced from 1990 to 2015, bringing the burden of premature deaths closer to expected rates given the country's Socio-demographic Index (SDI). In 1990, IHD, stroke, diarrhea, neonatal preterm birth complications, road injury, and violence had ratios higher than the expected, while in 2015 only violence was higher, overall and in all states, according to the SDI. CONCLUSIONS: A widespread reduction of mortality levels occurred in Brazil from 1990 to 2015, particularly among children under 5 years old. Major shifts in mortality rates took place among communicable, maternal, neonatal, and nutritional disorders. The mortality profile has shifted to older ages with increases in non-communicable diseases as well as premature deaths due to violence. Policymakers should address health interventions accordingly. PMID- 29166952 TI - Effects of dietary live yeast supplementation on growth performance, diarrhoea severity, intestinal permeability and immunological parameters of weaned piglets challenged with enterotoxigenic Escherichia coli K88. AB - This study aimed to investigate the effects of dietary live yeast (LY) supplementation on growth, intestinal permeability and immunological parameters of piglets challenged with enterotoxigenic Escherichia coli K88 (ETEC). Piglets weaned at 21 d were allocated into three treatments with six pens and six piglets per pen, receiving the control diet (CON), diets supplemented with antibiotics plus zinc oxide (ANT-ZnO) and LY (Saccharomyces cerevisiae strain CNCM I-4407), respectively, for a period of 2 weeks. On day 8, thirty-six piglets were selected as control without ETEC (CON), CON-ETEC, ANT-ZnO-ETEC and LY-ETEC groups challenged with ETEC until day 10 for sample collections. Piglets fed ANT-ZnO diet had the highest average daily gain and average daily feed intake (P<0.05) during the 1st week, but ADG of piglets fed the ANT-ZnO diet was similar as piglets fed LY diet during the second week. Piglets with LY-ETEC or ANT-ZnO-ETEC had markedly lower diarrhoea score (P<0.05) than piglets with CON-ETEC during the 24 h after ETEC challenge. Relative to piglets with CON, the counts of E. coli, urinary ratio of lactulose to mannitol, plasma IL-6 concentration, mRNA abundances of innate immunity-related genes in ileum and mesenteric lymph node tissues were increased (P<0.05), whereas the villous height of jejunum and relative protein expression of ileum claudin-1 were decreased (P<0.05) in piglets with CON-ETEC; however, these parameters did not markedly change in piglets with LY-ETEC or ANT-ZnO-ETEC. In summary, dietary LY supplementation could alleviate the severity of diarrhoea in piglets with ETEC, which may be associated with the improved permeability, innate immunity and bacterial profile. PMID- 29166953 TI - Mating system, age, and reproductive performance in Tenuisvalvae notata, a long lived ladybird beetle. AB - The long-lived polygynandrous ladybird beetle Tenuisvalvae notata (Mulsant) found in Brazil was evaluated in the laboratory for the effects of multiple mating and aging on its reproductive performance. This species is native to South America and is an important predator of mealybugs. Specifically studied were partner choice, female reproductive success, adult longevity, male virility, and offspring development. Young (5-10 days old) and older virgin females (95-100 days old) were subjected to either a single mate or multiple mating with the same or different males of various mating status (virgin or previously mated once, twice, and thrice). Results revealed a preference in both genders to mate with previously known partners. Additionally, younger females had higher fecundity and greater longevity when mated only once in comparison to those mated multiple times. Fecundity, fertility, and offspring development were similar across the treatments regardless of the number of mating or male mating history. Fecundity and fertility decreased throughout the oviposition period regardless of mating treatment. PMID- 29166954 TI - State-of-the-art for food taxes to promote public health. AB - The use of taxes to promote healthy nutritional behaviour has gained ground in the past decade. The present paper reviews existing applications of fiscal instruments in nutrition policy and derives some perspectives and recommendations from the experiences gained with these instruments. Many countries in different parts of the world have experiences with the taxation of sugar-sweetened beverages, in some cases in combination with taxes on unhealthy food commodities such as confectionery or high-fat foods. These tax schemes have many similarities, but also differ in their definitions of tax objects and in the applied tax rates. Denmark has been the only country in the world to operate a tax on saturated fat content in foods, from 2011 to 2012. Most of the existing food tax schemes have been introduced from fiscal motivations, with health promotion as a secondary objective, but a few have been introduced with health promotion as the primary objective. The diversity in experiences from existing tax schemes can provide valuable insights for future use of fiscal instruments to promote healthy nutrition, in terms of designing effective and efficient tax or subsidy instruments, and in terms of smooth and politically viable implementation of the instruments. PMID- 29166956 TI - Systematic review of infant and young child complementary feeding practices in South Asian families: the India perspective. AB - OBJECTIVE: Suboptimal nutrition among children remains a problem among South Asian (SA) families. Appropriate complementary feeding (CF) practices can greatly reduce this risk. Thus, we undertook a systematic review of studies assessing CF (timing, dietary diversity, meal frequency and influencing factors) in children aged <2 years in India. DESIGN: Searches between January 2000 and June 2016 in MEDLINE, EMBASE, Global Health, Web of Science, OVID Maternity & Infant Care, CINAHL, Cochrane Library, BanglaJOL, POPLINE and WHO Global Health Library. Eligibility criteria: primary research on CF practices in SA children aged 0-2 years and/or their families. Search terms: 'children', 'feeding' and 'Asians' and derivatives. Two researchers undertook study selection, data extraction and quality appraisal (EPPI-Centre Weight of Evidence). RESULTS: From 45 712 abstracts screened, sixty-four cross-sectional, seven cohort, one qualitative and one case-control studies were included. Despite adopting the WHO Infant and Young Child Feeding guidelines, suboptimal CF practices were found in all studies. In twenty-nine of fifty-nine studies, CF was introduced between 6 and 9 months, with eight studies finding minimum dietary diversity was achieved in 6-33 %, and ten of seventeen studies noting minimum meal frequency in only 25-50 % of the study populations. Influencing factors included cultural influences, poor knowledge on appropriate CF practices and parental educational status. CONCLUSIONS: This is the first systematic review to evaluate CF practices in SA in India. Campaigns to change health and nutrition behaviour and revision of nationwide child health nutrition programmes are needed to meet the substantial unmet needs of these children. PMID- 29166957 TI - DHA supplementation during pregnancy as phospholipids or TAG produces different placental uptake but similar fetal brain accretion in neonatal piglets. AB - The great variety of n-3 long-chain PUFA sources raises the question of the most adequate for using as a DHA supplement during pregnancy. Placental and fetal availability of different DHA sources remains unclear. We investigated DHA availability in maternal lipoproteins, placenta and fetal tissues in pregnant sows fed DHA as phospholipid (PL) or TAG to identify the best DHA source during this period. Pregnant Iberian sows were fed diets containing 0.8 % DHA of total fatty acids as PL from egg yolk or TAG from algae oil during the last third of gestation (40 d). Maternal tissues, placentas and fetal tissues were obtained at delivery and DHA quantified by GC. Major Facilitator Superfamily Domain Containing 2a (MFSD2a) carrier expression was analysed in both placenta and fetal brain by Western blotting. Sows fed the DHA-PL diet showed higher DHA incorporation in plasma LDL but not in plasma total lipids. No differences were found in DHA content between groups in maternal liver, adipose tissue or brain. Placental tissue incorporated more DHA in both total lipids and PL fraction in sows fed DHA-PL. However, this did not lead to an enhanced DHA accretion either in fetal plasma, fetal liver or fetal brain. MFSD2a expression was similar between both experimental groups. Maternal DHA supplementation during pregnancy in sow either as PL or TAG produces similar DHA accretion in fetal tissues but not in placenta. Both fat sources are equally available for fetal brain. PMID- 29166955 TI - Brain Arterial Diameters and Cognitive Performance: The Northern Manhattan Study. AB - OBJECTIVES: To test the hypothesis that brain arterial diameters are associated with cognitive performance, particularly in arteries supplying domain-specific territories. METHODS: Stroke-free participants in the Northern Manhattan Study were invited to have a brain MRI from 2003-2008. The luminal diameters of 13 intracranial arterial segments were obtained using time-of-flight magnetic resonance angiogram (MRA), and then averaged and normalized into a global score and region-specific arterial diameters. Z-Scores for executive function, semantic memory, episodic memory and processing speed were obtained at MRI and during follow-up. Adjusted generalized additive models were used to assess for associations. RESULTS: Among the 1034 participants with neurocognitive testing and brain MRI, there were non-linear relationships between left anterior (ACA) and middle cerebral artery (MCA) diameter and semantic memory Z-scores (chi2=10.00; DF=3; p=.019), and left posterior cerebral artery (PCA) and posterior communicating artery (Pcomm) mean diameter and episodic memory Z-scores (chi2=9.88; DF=3; p=.020). Among the 745 participants who returned for 2nd neuropsychological testing, on average 5.0+/-0.4 years after their MRI, semantic memory change was associated non-linearly with the left PCA/Pcomm mean diameter (chi2=13.09; DF=3; p=.004) and with the right MCA/ACA mean diameter (chi2=8.43; DF=3; p=.03). In both cross-sectional and longitudinal analyses, participants with the larger brain arterial diameters had more consistently lower Z-scores and greater decline than the rest of the participants. CONCLUSIONS: Brain arterial diameters may have downstream effects in brain function presenting as poorer cognition. Identifying the mechanisms and the directionality of such interactions may increase the understanding of the vascular contribution to cognitive impairment and dementia. (JINS, 2018, 24, 335-346). PMID- 29166958 TI - Insights into the factors associated with achieving the preference of home death in terminal cancer: A national population-based study. AB - OBJECTIVES: Most terminally ill cancer patients prefer to die at home, yet only a minority are able to achieve this. Our aim was to investigate the factors associated with cancer patients achieving their preference to die at home. METHODS: This study took the form of a mortality followback, population-based, observational survey of the relatives of deceased cancer patients in Northern Ireland. Individuals who registered the death of a friend or relative (aged >= 18 years) between 1 December 2011 and 31 May 2012, where the primary cause of death was cancer (ICD10: C00-D48), who were invited to take part. Preferred and actual place of death, and patient, service, and clinical data were collected using the QUALYCARE postal questionnaire. Multivariable logistic regression was employed to investigate the factors associated with achieving a home death when preferred. RESULTS: Some 467 of 1,493 invited informants completed the survey. The 362 (77.5%) who expressed a preference for dying at home and spent time at home in their final 3 months were included in our analysis. Of these, 53.4% achieved their preference of a home death. Factors positively associated with achieving a home death were: living in an affluent area, receipt of good and satisfactory district nurse care, discussing place of death with health professionals, and the caregiver's preference for a home death. Being older than 80 years of age, being a Presbyterian, and being unconscious most of the time during their final week were negatively associated with achieving a home death. SIGNIFICANCE OF RESULTS: Communication, care satisfaction, and caregiver preferences were all associated with home death. Our findings will help inform the design of future interventions aimed at increasing the proportion of patients achieving their preferred place of death at home, for example, by targeting interventions toward older patients and those from the most deprived communities. PMID- 29166959 TI - Short-distance dispersal of Hypothenemus hampei (Ferrari) females (Coleoptera: Curculionidae: Scolytidae) during the coffee tree fruiting period. AB - The coffee berry borer (CBB), Hypothenemus hampei (Ferrari), is a multivoltine species closely associated with coffee crops worldwide, causing severe damage to the bean. In Mexico, as in all tropical regions, CBB survives during the inter harvest period in residual berries on the ground or in dry berries remaining on the branches, and then disperses in search of the first suitable berries. In this study, we investigated how CBB dispersed from the first infested nodes during the fruiting period of Coffea canephora Pierre, which provides a favourable trophic level for this insect. Forty-five branches equally distributed in 15 coffee trees, with one infested node and four uninfested nodes, were selected. The branches were subjected to three treatments over nine weeks: 1) glue between nodes with full protection, 2) glue between nodes without protection, and 3) no glue and no protection. In addition, 45 CBB-free branches were selected and subjected to the same three treatments. CBB colonization can occur in three ways: 1) from an infested node to an uninfested node on the same branch, 2) from infested berries to uninfested berries within the nodes, 3) from branches to other branches. We also found that CBB dispersal between nodes of the same branches never occurred by walking but by flying. Thus, in this context of coffee berry development and ripening, and unlike the phenological situation of the inter-harvest period, CBB continuously travels very short distances, thus limiting its control.

PMID- 29166961 TI - Antibiotic resistance trends and mechanisms in the foodborne pathogen, Campylobacter. AB - Campylobacter is a major foodborne pathogen and is commonly present in food producing animals. This pathogenic organism is highly adaptable and has become increasingly resistant to various antibiotics. Recently, both the Centers for Disease Control and Prevention and the World Health Organization have designated antibiotic-resistant Campylobacter as a serious threat to public health. For the past decade, multiple mechanisms conferring resistance to clinically important antibiotics have been described in Campylobacter, and new resistance mechanisms constantly emerge in the pathogen. Some of the recent examples include the erm(B) gene conferring macrolide resistance, the cfr(C) genes mediating resistance to florfenicol and other antimicrobials, and a functionally enhanced variant of the multidrug resistance efflux pump, CmeABC. The continued emergence of new resistance mechanisms illustrates the extraordinary adaptability of Campylobacter to antibiotic selection pressure and demonstrate the need for innovative strategies to control antibiotic-resistant Campylobacter. In this review, we will briefly summarize the trends of antibiotic resistance in Campylobacter and discuss the mechanisms of resistance to antibiotics used for animal production and important for clinical therapy in humans. A special emphasis will be given to the newly discovered antibiotic resistance. PMID- 29166962 TI - Biology of two larval morphological phenotypes of Aedes aegypti in Abidjan, Cote d'Ivoire. AB - Since 2008, several outbreaks of yellow fever and dengue occurred in Abidjan, the economic capital of Cote d'Ivoire. A better knowledge of the biology of Aedes aegypti populations, the main vector of yellow fever and dengue viruses, is necessary to tailor vector control strategies implemented in the city. This study was designed to determine some biological parameters, occurring during the life cycle of two morphological phenotypes of Ae. aegypti larvae. Mosquitoes were sampled in a suburb of Abidjan (Treichville) using the WHO layer-traps technique. Biological parameters were studied in laboratory under standard conditions of temperature (27 degrees C +/- 2 degrees C) and relative humidity (80% +/- 10%). Our results indicated that the mean eggs laid by females from 'brown larvae' (BL) (85.95, 95% confidence interval (CI 95%) 78.87-93.02) was higher than those from 'white larvae' (WL) (64.40%, CI 95% 55.27-73.54). The gonotrophic cycle was 3 and 4 days in females from BL and WL, respectively. The overall yield of breeding mosquitoes from BL (63.88%, CI 95% 62.61-65.14) was higher compared with those of mosquitoes from WL (59.73%, CI 95% 58.35-61.12). The sex ratio (male/female) was 0.95 and 1.68 in Ae. aegypti populations from BL and WL, respectively. Females from BL lived slightly longer than those from WL (t = -2.332; P = 0.021). This study shows that Ae. Aegypti populations from BL and WL present different biological parameters during their life cycle. This could have an implication on their ability to transmit human disease viruses such as dengue and yellow fever. Further molecular studies are needed to determine genetic divergence between these Ae. aegypti populations. PMID- 29166963 TI - Anatomical, morphological, and physiological responses of two sugarcane genotypes of contrasting susceptibility to Mahanarva fimbriolata (Hemiptera: Cercopidae). AB - The purpose of this study was to investigate and compare root morpho-anatomical traits and physiological responses of susceptible (SP81-3250) and resistant (H. Kawandang) sugarcane genotypes exposed to the attack by nymphs of spittlebug Mahanarva fimbriolata (Stal) (Hemiptera: Cercopidae). Two experiments were conducted to compare the damage caused by spittlebug nymphs on fresh and dry biomass weight; lignin content in stalks; root anatomy; chlorophyll content; photosynthetic rate (A); carboxylation efficiency (A/Ci); stomatal conductance (gS) and transpiration rate (E) of these genotypes. SP81-3250 consistently obtained significantly higher damage scores than H. Kawandang in both experiments, confirming the previously observed level of resistance in each genotype. Attack by spittlebug nymphs had a much higher effect on both fresh and dry biomass weight, chlorophyll content, A, A/Ci, gs and E of SP81-3250, than that on H. Kawandang. Anatomical studies indicated the presence of aerenchyma tissue in the root cortex of SP81-3250, a feature which may facilitate penetration of the nymph's stylet into the vascular cylinder. In contrast, roots of H. Kawandang are characterized by having more dense and compact parenchyma cells. In addition, infested plants of this genotype contained an unidentified mucilaginous compound in the vascular cylinder of the roots. We conclude that resistance of H. Kawandang to spittlebug is related to the ability of this genotype to maintain normal chlorophyll content, as well as stomatal conductance and photosynthesis, thus, allowing for biomass accumulation under spittlebug attack, in contrast to SP81-3250. In addition, the presence of more compact and denser parenchymal cells, as well as that of an induced mucilaginous compound in the root's vascular cylinder, are likely to hinder host-feeding activity in nymphs, causing higher nymph mortality and therefore, reduced damage in plants of this genotype. PMID- 29166964 TI - How do childhood intelligence and early psychosocial adversity influence income attainment among adult extremely low birth weight survivors? A test of the cognitive reserve hypothesis. AB - Perinatal and later postnatal adversities have been shown to adversely affect socioeconomic trajectories, while enhanced early cognitive abilities improve them. However, little is known about the combined influence of these exposures on social mobility. In this study, we examined if childhood IQ moderated the association between four different types of postnatal adversity (childhood socioeconomic disadvantage, childhood sexual abuse, lifetime psychiatric disorder, and trait neuroticism) and annual earnings at 30-35 years of age in a sample of 88 extremely low birth weight survivors. Our results suggested that higher childhood IQ was associated with greater personal income at age 30-35. Extremely low birth weight survivors who did not face psychological adversities and who had higher childhood IQ reported higher income in adulthood. However, those who faced psychological adversity and had higher childhood IQ generally reported lower income in adulthood. Our findings suggest that cognitive reserve may not protect preterm survivors against the complex web of risk factors affecting their later socioeconomic attainment. PMID- 29166965 TI - Environmental determinants of haemosporidian parasite prevalence in a declining population of Tree swallows. AB - The prevalence of vector-borne parasites such as haemosporidian species is influenced by several environmental factors. While the negative effects of parasitism on hosts are well documented, these can also be amplified by interactions with environmental stressors, many of which are anthropogenic. Yet, we know little about the possible effects of anthropogenic perturbations on parasite prevalence. The goals of this study were to assess the prevalence and environmental determinants of haemosporidian parasites in a declining population of Tree swallows (Tachycineta bicolor) living in an agricultural landscape in southern Quebec, Canada. Overall, a low prevalence and a moderate lineage diversity were identified in both adults and nestlings, confirming that transmission can occur during the breeding period. Anthropic areas, extensive cultures (hayfields and pastures) and forest cover within 500 km of nest boxes, as well as daily temperature fluctuations, were all related to infection by haemosporidian parasites. These findings suggest that anthropogenic alterations of landscape composition can modulate the prevalence of haemosporidian parasites in Tree swallows. Our results represent a baseline for future comparative studies assessing haemosporidian parasite prevalence in human-modified landscapes. PMID- 29166966 TI - The feeding system impacts relationships between calving interval and economic results of dairy farms. AB - The calving interval (CI) can potentially impact the economic results of dairy farms. This study highlighted the most profitable CI and innovated by describing this optimum as a function of the feeding system of the farm. On-farm data were used to represent real farm conditions. A total of 1832 accounts of farms recorded from 2007 to 2014 provided economic, technical and feeding information per herd and per year. A multiple correspondence analysis created four feeding groups: extensive, low intensive, intensive and very intensive herds. The gross margin and some of its components were corrected to account for the effect of factors external to the farm, such as the market, biological status, etc. Then the corrected gross margin (cGMc) and its components were modelled by CI parameters in each feeding system by use of GLM. The relationship between cGMc and the proportion of cows with CI<380 days in each feeding group showed that keeping most of the cows in the herd with CI near to 1 year was not profitable for most farms (for the very intensive farms there was no effect of the proportion). Moreover, a low proportion of cows (0% to 20%) with a near-to-1-year CI was not profitable for the extensive and low intensive farms. Extending the proportion of cows with CI beyond 459 days until 635 days (i.e. data limitation) caused no significant economic loss for the extensive and low intensive farms, but was not profitable for the intensive and very intensive farms. Variations of the milk and feeding components explained mainly these significant differences of gross margin. A link between the feeding system and persistency, perceptible in the milk production and CI shown by the herd, could explain the different relationships observed between the extent of CI and the economic results in the feeding groups. This herd-level study tended to show different economic optima of CI as a function of the feeding system. A cow-level study would specify these tendencies to give CI objectives to dairy breeders as a function of their farm characteristics.

PMID- 29166968 TI - Infant feeding practices and dietary consumption of US infants and toddlers: National Health and Nutrition Examination Survey (NHANES) 2003-2012. AB - OBJECTIVE: To compare infant and toddler anthropometric measurements, feeding practices and mean nutrient intakes by race/ethnicity and income. DESIGN: Cross sectional analysis using general linear modelling. Ten years of survey data (2003 2012) were combined to compare anthropometric measurements, feeding practices and mean nutrient intakes from a nationally representative US sample. SETTING: The 2003-2012 National Health and Nutrition Examination Survey (NHANES). SUBJECTS: Infants and toddlers (n 3669) aged 0-24 months. RESULTS: Rates of overweight were higher among Mexican-American infants and toddlers (P=0.002). There were also several differences in feeding practices among groups based on race/ethnicity. Cessation of breast-feeding occurred earlier for non-Hispanic black and Mexican American v. non-Hispanic white infants (3.6 and 4.2 v. 5.3 months; P<0.0001; P=0.001). Age at first feeding of solids was earlier for white than Mexican American infants (5.3 v. 5.7 months; P=0.02). There were differences in almost all feeding practices based on income, including the lowest-income infants stopped breast-feeding earlier than the highest-income infants (3.2 v. 5.8 months, P<0.0001). Several differences in mean nutrient intakes by both race/ethnicity and income were also identified. CONCLUSIONS: Our study indicates that disparities in overweight, feeding practices and mean nutrient intakes exist among infants and toddlers according to race/ethnicity, which cannot be disentangled from income. PMID- 29166969 TI - HOW TO AVOID GIVING THE RIGHT ANSWERS TO THE WRONG QUESTIONS: THE NEED FOR INTEGRATED ASSESSMENTS OF COMPLEX HEALTH TECHNOLOGIES. AB - Health technologies are becoming increasingly complex and contemporary health technology assessment (HTA) is only partly equipped to address this complexity. The project "Integrated assessments of complex health technologies" (INTEGRATE HTA), funded by the European Commission, was initiated with the overall objective to develop concepts and methods to enable patient-centered, integrated assessments of the effectiveness, and the economic, social, cultural, and ethical issues of complex technologies that take context and implementation issues into account. The project resulted in a series of guidances that should support the work of HTA scientists and decision makers alike. PMID- 29166970 TI - The role of low-calorie sweeteners in the prevention and management of overweight and obesity: evidence v. conjecture. AB - By virtue of reducing dietary energy density, low-calorie sweeteners (LCS) can be expected to decrease overall energy intake and thereby decrease body weight. Such effects will be limited by the amount of sugar replaced by LCS, and the dynamics of appetite and weight control (e.g., acute compensatory eating, and an increase in appetite and decrease in energy expenditure accompanying weight loss). Consistent with these predictions, short-term intervention studies show incomplete compensation for the consumption of LCS v. sugar, and longer-term intervention studies (from 4 weeks to 40 months duration) show small decreases in energy intake and body weight with LCS v. sugar. Despite this evidence, there are claims that LCS undermine weight management. Three claims are that: (1) LCS disrupt the learned control of energy intake (sweet taste confusion hypothesis); (2) exposure to sweetness increases desire for sweetness (sweet tooth hypothesis); (3) consumers might consciously overcompensate for 'calories saved' when they know they are consuming LCS (conscious overcompensation hypothesis). None of these claims stands up to close examination. In any case, the results of the intervention studies comparing LCS v. sugar indicate that the effect of energy dilution outweighs any tendency LCS might conceivably have to increase energy intake. PMID- 29166971 TI - A review on metronidazole: an old warhorse in antimicrobial chemotherapy. AB - The 5-nitroimidazole drug metronidazole has remained the drug of choice in the treatment of anaerobic infections, parasitic as well as bacterial, ever since its development in 1959. In contrast to most other antimicrobials, it has a pleiotropic mode of action and reacts with a large number of molecules. Importantly, metronidazole, which is strictly speaking a prodrug, needs to be reduced at its nitro group in order to become toxic. Reduction of metronidazole, however, only takes place under very low concentrations of oxygen, explaining why metronidazole is exclusively toxic to microaerophilic and anaerobic microorganisms. In general, resistance rates amongst the pathogens treated with metronidazole have remained low until the present day. Nevertheless, metronidazole resistance does occur, and for the treatment of some pathogens, especially Helicobacter pylori, metronidazole has become almost useless in some parts of the world. This review will give an account on the current status of research on metronidazole's mode of action, metronidazole resistance in eukaryotes and prokaryotes, and on other 5-nitroimidazoles in use.

AB - High-dose vitamin A supplementation (VAS) may affect mortality to infectious diseases in a sex-differential manner. Here, we analysed the long-term immunological effects of neonatal vitamin A supplementation (NVAS) in 247 children, who had been randomly allocated to 50 000 or 25 000 IU vitamin A (15mg and 7.5mg retinol equivalents, respectively) or placebo at birth. At 4-6 months of age, we assessed bacille Calmette-Guerin (BCG) scarification, and we analysed in vitro responses of TNF-alpha, IL-5, IL-10, IL-13 and IFN-gamma in whole blood stimulations to phytohaemagglutinin (PHA), purified protein derivative (PPD), tetanus toxoid and lipopolysaccharide. There were no differences between the two doses of NVAS, and thus they were analysed combined as NVAS (any dose) v. placebo. All analyses were performed unstratified and by sex. NVAS increased the chance of having a scar after BCG vaccination in females (NVAS v. placebo: 96 v. 71 %, proportion ratio: 1.24; 95 % CI 1.09, 1.42), but not in males (P for interaction=0.012). NVAS was associated with significant sex-differential effects on the pro- to anti-inflammatory cytokine ratios (TNF-alpha:IL-10) to PPD, tetanus toxoid and medium alone, which were increased in females but decreased in males. In addition, IL-17 responses tended to be increased in NVAS v. placebo recipients in males but not in females, significantly so for the PHA stimulation. The study corroborates sex-differential effects of VAS on the immune system, emphasising the importance of analysing VAS effects by sex. PMID- 29166973 TI - Effectiveness of a Behavioral Approach to Improve Healthcare Worker Compliance With Hospital Dress Code. AB - BACKGROUND The VU University Medical Center, a tertiary-care hospital in the Netherlands, has adopted a dress code based on national guidelines. It includes uniforms provided by the hospital and a 'bare-below-the-elbow' policy for all healthcare workers (HCWs) in direct patient care. Because compliance was poor, we sought to improve adherence by interventions targeted at the main causes of noncompliance. OBJECTIVE To measure compliance with the dress code, to assess causes of noncompliance and to assess whether a behavioral approach (combing a nominal group technique with participatory action) is effective in improving compliance METHODS Between March 2014 and June 2016, a total of 1,920 HCWs were observed in hospital hallways for adherence to the policy, at baseline, and at follow-up measurements. Based on the outcome of the baseline measurement, a nominal group technique was applied to assess causes of noncompliance. The causes revealed served as input for interventions that were developed, prioritized, and tailored to specific groups of HCWs and specific departments through participatory action. RESULTS We identified lack of knowledge, lack of facilities, and negative attitudes as the main causes of noncompliance. The importance of each cause varied for different groups of HCWs. Tailored interventions targeted at these causes increased overall compliance by 39.6% (95% CI, 31.7-47.5). CONCLUSION The combination of a nominal group technique and participatory action approach is an effective method to increase and sustain compliance with hospital dress code. This combined approach may also be useful to improve adherence to other guidelines. Infect Control Hosp Epidemiol 2017;38:1435 1440. PMID- 29166974 TI - A first qualitative snapshot: cardiac surgery and recovery in 10 children in the Red Cross War Memorial Children's Hospital, Cape Town, South Africa (2011-2016). AB - This article describes our qualitative research on the follow-up of 10 children, 5 years into recovery after cardiac surgery. The research was driven by a multi disciplinary team of medical anthropologists, cardiologists, and an intensive care specialist and was based at the Red Cross War Memorial Children's Hospital where they underwent surgeries. The research sought to answer two questions; first, could we successfully maintain contact with and follow up the children; the second - which will be answered in future papers - asked what life was like for them and their families during surgery and later recovery. The results are presented as a discussion on the themes that arose in our engagement and analysis and not as clinical evidence. These showed that elective surgery although significantly delayed was successful, and all children were followed up at their medical appointments. The researchers, however, were unable to establish follow up with all families over the duration of the study. In the final round of interviews in the respondents' homes, of 10 children, we remained in contact with seven. The discussion argues that effective communication and access to these children was often compromised by their coming from the poorer communities in the Cape Town metropolitan region, making them even more vulnerable during their recovery periods. PMID- 29166975 TI - In vitro and in vivo efficacy of diamidines against Trypanosoma equiperdum strains. AB - Trypanosoma equiperdum is a protozoan parasite responsible for causing Dourine, a debilitating neglected veterinary disease, found worldwide affecting equids. It is the only pathogenic trypanosome species that does not require an invertebrate vector for transmission, thus being passed from animal to animal via coitus. At present, there is no officially recognized form of chemotherapeutic treatment and therefore all confirmed (or suspected) cases of infected animals must be slaughtered immediately. For many global communities and farming populations, which rely heavily on their animals for their livelihood, such stringent regulations can seriously enhance the socio-economic problems attributing to poverty. Two reference drugs, together with 37 novel diamidine compounds were tested in vitro using a 72 h drug sensitivity assay to determine their efficacy against two axenically adapted T. equiperdum strains. Further in vivo investigations in mouse models of infection against 4 'true' T. equiperdum strains were performed using the 17 most active diamidines. Single bolus doses of 10 mg kg-1, given i.p. were administered to NMRI mice infected with one of the 4 T. equiperdum strains. The results obtained from this study show that experimentally T. equiperdum can indeed be effectively treated with chemotherapy using in vivo mouse models of infection. PMID- 29166976 TI - Clinical, laboratory and epidemiological aspects of HPV infection in a low-income population from South Bahia, Brazil. AB - The aim of this study was to determine the prevalence and risk factors for human papillomavirus (HPV) infection in the Southern region of the State of Bahia, evaluating the performance of alternative complementary methods for cervical lesion detection. Cervical samples from women who attended healthcare units were collected and diagnosed by visual inspection, cervical cytology and nested polymerase chain reaction (PCR). Moreover, hemi-nested PCR was performed to detect different HPV genotypes. The prevalence of HPV infection was 47.7%, with genotype 16 detected in most cases. Infection was associated with dyspareunia and bleeding (P < 0.001, odds ratio (OR) 5.6, 95% confidence interval (CI) 2.815 11.14) and hormonal contraceptive use (P = 0.007, OR 2.33, 95% CI 1.25-4.34). There was a positive correlation between positive PCR and positive visual inspection, cervical cytology and symptoms reported. Furthermore, visual inspection was twice as specific, and had a greater positive predictive value than cytology. We showed a high prevalence of HPV infection in Southern Bahia, with HPV 16 being the most common type, and visual inspection being most effective at detecting HPV lesions, corroborating the suggestion that it can be applied in routine gynecologic examinations for low-income populations. PMID- 29166977 TI - Analysis of pre-weaning feeding policies and other risk factors influencing growth rates in calves on 11 commercial dairy farms. AB - Growth rates in pre-weaned calves influence their health, age at first calving and lifetime productivity. Many farms restrict milk rations to encourage solid feed intake and facilitate early weaning, but this can compromise growth. This study determined the milk feeding policies and associated growth rates on 11 commercial dairy farms in South East England, each following their normal management regime. Between 26 and 54 heifers were recruited per farm, providing a final cohort of 492, of which 71% were pure Holstein. Information on calf rearing practices (feeding, weaning, housing) and health was collected via questionnaires and weekly observations. Estimates of actual milk fed (kg solids) between 1 and 63 days were calculated for individual calves. Morphometric data (weight, height, length) were taken at weeks 1, 5 and 9 and at a median age of 7.5 months and growth rates were calculated. Most calves were fed milk replacer via automated feeders (four farms), teat feeder (one) or buckets (four) whereas two farms provided drums of acidified waste milk. Farms fed between 4 and 6 l/day of milk at mixing rates of 10% to 15%, providing 400 to 900 g/day of milk solids. Both skeletal growth rates and average daily weight gain (ADG) increased in the second month of life compared with the first: height growth from 0.17+/-0.14 to 0.25+/ 0.16 cm/day and ADG from 0.48+/-0.25 to 0.71+/-0.28 kg/day. Post-weaning heifers up to 7.5 months had height increases of 0.16+/-0.035 cm/day and ADG of 0.83+/ 0.16 kg/day. From 1 to 63 days 70% of calves had growth rates <0.7 kg/day and of these 19.6% gained <0.5 kg/day. Mean ADG before 9 weeks varied between farms from 0.52+/-0.30 to 0.75+/-0.20 kg/day. This was related to the amount of milk fed at both a farm and individual calf level. Increasing the total milk solids fed between 1 and 63 days from 20.4 to 46.3 kg (the 10th to 90th percentile observed) was associated with an increase of 0.11 kg/day ADG. All farms had a wide variation in growth rates despite single feeding policies. Higher circulating immunoglobulin G and IGF1 concentrations were associated with better growth, whereas low temperatures in month of birth, high scores for diarrhoea, respiratory and umbilical disease and large birth size reduced growth. Many commercially grown dairy heifers therefore experienced growth restriction in the pre-weaned period, potentially reducing their health, welfare and productivity. PMID- 29166978 TI - Molecular detection of influenza A(H1N1)pdm09 viruses with M genes from human pandemic strains among Nigerian pigs, 2013-2015: implications and associated risk factors. AB - In the post-pandemic period, influenza A(H1N1)pdm09 virus has been detected in swine populations in different parts of the world. This study was conducted to determine the presence and spatial patterns of this human pandemic virus among Nigerian pigs and identify associated risk factors. Using a two-stage stratified random sampling method, nasal swab specimens were obtained from pigs in Ibadan, Nigeria during the 2013-2014 and 2014-2015 influenza seasons, and the virus was detected by reverse transcriptase-polymerase chain reaction (RT-PCR). Purified RT PCR products were sequenced in both directions, and sequences were aligned using MUSCLE. Phylogenetic analysis was conducted in MEGA6. Purely spatial scan statistics and a spatial lag regression model were used to identify spatial clusters and associated risk factors. The virus was detected in both seasons, with an overall prevalence of 8.7%. Phylogenetic analyses revealed that the M genes were similar to those of pandemic strains which circulated in humans prior to and during the study. Cluster analysis revealed a significant primary spatial cluster (RR = 4.71, LLR = 5.66, P = 0.0046), while 'hours spent with pigs (R 2 = 0.90, P = 0.0018)' and 'hours spent with pigs from different farms (R 2 = 0.91, P = 0.0001)' were identified as significant risk factors (P < 0.05). These findings reveal that there is considerable risk of transmission of the pandemic virus, either directly from pig handlers or through fomites, to swine herds in Ibadan, Nigeria. Active circulation of the virus among Nigerian pigs could enhance its reassortment with endemic swine influenza viruses. Campaigns for adoption of biosecurity measures in West African piggeries and abattoirs should be introduced and sustained in order to prevent the emergence of a new influenza epicentre in the sub-region. PMID- 29166979 TI - Explaining variations in the diversity of parasitoid assemblages in a biosphere reserve of Mexico: evidence from vegetation, land management and seasonality. AB - Insect fauna biodiversity in natural protected areas has not been thoroughly studied. Therefore, the aim of this work was to assess whether and how vegetation types, land management and seasonality influence the diversity of Ichneumonidae (Hymenoptera) in the Ria Lagartos Biosphere Reserve (Mexico). A sampling programme was conducted using Malaise traps from 2008 to 2009 in three vegetation types, each with two conservation zones (core and buffer zones). Three seasons were considered: rainy, dry and north-winds (isolated storms from November to February). A total of 336 species were identified. Rarefaction and Generalized Linear Model indicated higher species richness and abundance, respectively, in the buffer zone of the dry forest; possible explanations for this finding include the intermediate disturbance hypothesis, wherein diversity can be higher in sites where disturbance is not very frequent or very intense, and the 'enemies hypothesis', wherein structural complexity and high plant diversity favour increased predators or, in this case, parasitoids. Diversity was higher during the rainy season, which may have been due to the higher availability of resources. Vegetation and management had a positive impact on the Coc (attack cocoons and pupae) and Myc (attack concealed larvae living in the fruiting bodies of mushrooms) parasitoid guilds. Members of the Coc guild are generalist parasitoids, which may be favoured in complex vegetation with a high richness of potential hosts and non-hosts. The Myc guild requires certain environmental conditions that promote fungal growth, such as humidity, that is absent in the other vegetation types of savannah and coastal dune scrubland. PMID- 29166980 TI - Determination of the efficiency of diets for larval development in mass rearing Aedes aegypti (Diptera: Culicidae). AB - Larval diet quality and rearing conditions have a direct and irreversible effect on adult traits. Therefore, the current study was carried out to optimize the larval diet for mass rearing of Aedes aegypti, for Sterile Insect Technique (SIT) based applications in Sri Lanka. Five batches of 750 first instar larvae (L1) of Ae. aegypti were exposed to five different concentrations (2-10%) of International Atomic Energy Agency (IAEA) recommended the larval diet. Morphological development parameters of larva, pupa, and adult were detected at 24 h intervals along with selected growth parameters. Each experiment was replicated five times. General Linear Modeling along with Pearson's correlation analysis were used for statistical treatments. Significant differences (P < 0.05) among the larvae treated with different concentrations were found using General Linear Modeling in all the stages namely: total body length and the thoracic length of larvae; cephalothoracic length and width of pupae; thoracic length, thoracic width, abdominal length and the wing length of adults; along with pupation rate and success, sex ratio, adult success, fecundity and hatching rate of Ae. aegypti. The best quality adults can be produced at larval diet concentration of 10%. However, the 8% larval diet concentration was most suitable for adult male survival.

PMID- 29166981 TI - Organic vs. organic - soil arthropods as bioindicators of ecological sustainability in greenhouse system experiment under Mediterranean conditions. AB - Organic greenhouse (OGH) production is characterized by different systems and agricultural practices with diverse environmental impact. Soil arthropods are widely used as bioindicators of ecological sustainability in open field studies, while there is a lack of research on organic production for protected systems. This study assessed the soil arthropod abundance and diversity over a 2-year crop rotation in three systems of OGH production in the Mediterranean. The systems under assessment differed in soil fertility management: SUBST - a simplified system of organic production, based on an input substitution approach (use of guano and organic liquid fertilizers), AGROCOM - soil fertility mainly based on compost application and agroecological services crops (ASC) cultivation (tailored use of cover crops) as part of crop rotation, and AGROMAN - animal manure and ASC cultivation as part of crop rotation. Monitoring of soil fauna was performed by using pitfall traps and seven taxa were considered: Carabidae, Staphylinidae, Araneae, Opiliones, Isopoda, Myriapoda, and Collembola. Results demonstrated high potential of ASC cultivation as a technique for beneficial soil arthropod conservation in OGH conditions. SUBST system was dominated by Collembola in all crops, while AGROMAN and AGROCOM had more balanced relative abundance of Isopoda, Staphylinidae, and Aranea. Opiliones and Myriapoda were more affected by season, while Carabidae were poorly represented in the whole monitoring period. Despite the fact that all three production systems are in accordance with the European Union regulation on organic farming, findings of this study displayed significant differences among them and confirmed the suitability of soil arthropods as bioindicators in protected systems of organic farming. PMID- 29166983 TI - Comparison Study of Body Image Satisfaction Between Beginning- and Advanced-Level Female Ballet Students. AB - This mixed methods study compares the level of satisfaction with one's body image between beginning- and advanced-level female collegiate ballet students. Thirty six beginning-level students were enrolled in two ballet classes, and a second group of 16 advanced-level students was enrolled in a third class. A mirror was used in the teaching of both groups. During the first and thirteenth week of a 14 week semester, students completed the Cash 69-item Body Self-Relations Questionnaire. In addition, five students from each group were randomly selected to participate in semi-structured interviews during the second and last week of the semester. Researchers asked students questions about their kinesthetic experience and the mirror's role in the studio. The quantitative results indicated that over the course of the semester the beginning dancers decreased in feeling physically fit, while the advanced dancers felt more in shape. For both beginning and advanced dancers there was a decrease in body image satisfaction. By semester's end, the advanced dancers were more preoccupied with weight and exercised more than the beginning dancers. The interviews revealed that four out of the five beginning ballet students discussed the use of the mirror in class and reported experiencing thoughts and sensations characteristic of the objective self-awareness state, such as heightened self-consciousness, comparison of self to others, or negative self-evaluation. The advanced dancers, on the other hand, focused on developing ways to avoid the mirror and preferred to "feel" movements muscularly before using the mirror for feedback. Even though the advanced dancers had more knowledge of how to use a mirror beneficially in class, their body image scores were equally as compromised as the beginning students'. These results suggest that both beginning- and advanced-level ballet students experience a decrease in body image satisfaction in a mirrored studio environment. PMID- 29166984 TI - A Comparison of Musculo-Articular Stiffness and Maximal Isometric Plantar Flexion and Knee Extension Force in Dancers and Untrained Individuals. AB - Dance involves a high volume of aesthetic, stretch-shortening cycle (SSC) actions, which may cause unique adaptations to performance. The strength dancers possess to withstand such frequency of SSCs remains elusive. The extensive training that dancers experience from a young age, however, yields anatomical and strength development that may contrast with that of untrained individuals. Therefore, the purpose of this study was to investigate differences in musculo articular stiffness and maximal isometric plantar flexion and knee extension force between dancers and untrained individuals. A total of 16 females volunteered to participate in the study (N = 8 dancers; N = 8 untrained individuals). Dancers had a minimum of 10 years of dance experience and were currently training at the collegiate dance level three or more times per week. Untrained individuals had no dance background, nor were they currently involved in any form of regularized physical activity. All subjects completed a series of lower leg measurements and strength tests. This included a musculo-articular stiffness measurement using a free-oscillation technique, along with maximal isometric plantar flexion (MIP) and maximal isometric knee extension (MIKE) testing. The data indicate that dancers had a significantly greater rate of force development and peak force during MIP and rate of force development during MIKE in comparison to untrained individuals. Dancers also possessed significantly greater musculo-articular stiffness. Hence, the data provide some evidence that involvement in dance can result in greater muscle force generating capacity and musculo-articular stiffness due to the SSC mechanisms involved in dance movements. PMID- 29166985 TI - Postural Control During Different Unipodal Positions in Professional Ballet Dancers. AB - Classical ballet involves the performance of complex movements that require high level motor skills and good postural control. This study explored postural sway in passe en demi-pointe position in dancers and compared single-leg standing sway (with and without visual restriction) between dancers and non-dancers. Fourteen professional dancers and 14 sex- and age-matched volunteers who were not ballet dancers participated in the study. Participants stood on a force plate on the dominant leg in the following positions: 1. single-leg stance with eyes open (reference task) and with eyes closed and blindfolded for 35 seconds; and 2. passe en demi-pointe position with eyes open for 20 seconds (dancers only). The center of pressure signal was used to calculate the following variables: average velocity; anteroposterior and mediolateral velocity peaks; anteroposterior and mediolateral displacement ranges; average displacement; and ellipse area. Significant interaction effects (p < 0.001, eta2 = 0.419) were observed between groups and postural tasks, with higher stabilometric values for the dancer group during the single-leg stance with eyes closed and blindfolded task, as evidenced by the average displacement of 241.0 cm in dancers and 147.1 cm in non-dancers (p = 0.025), and by the ellipse area of 9.5 cm2 for dancers and 4.9 cm2 for non dancers (p = 0.001). In regard to the positions with eyes open, an increase was noted only in the average sway velocity and mediolateral velocity in passe en demi-pointe position compared with the single-leg stance with eyes open (p < 0.001). Greater postural sway might be interpreted as the result of either inadequate postural stability or exploratory behavior to maintain postural stability in more challenging tasks. It is concluded that professional ballet dancers show greater visual dependency for balance adjustment with reduced influence of the supporting base on postural sway. PMID- 29166986 TI - A Retrospective Assessment of Return to Function in Dance After Physical Therapy for Common Dance Injuries. AB - An injury that causes a dancer to take time away from training or performance can be career ending, and thus it is important for dancers to have accurate expectations when considering treatment options. Thus far, few studies have reported functional outcomes after injury in dancers, which may be different than for the general athletic population. Therefore, our study sought to determine functional outcomes in dancers after operative and non-operative treatment for common dance injuries. Our outcome measures included a subjective assessment of the degree to which a dancer had returned to his or her previous level of dance, the SF-12 survey, and the WHO functional outcome scale modified for dance. We also compared these as outcome measurement tools for return to full function in dance. Secondarily, we sought to assess factors that may have contributed to poorer functional outcomes. We reviewed the charts of 675 dancers seen at our physical therapy facilities between 2006 and 2010 and identified 416 adult dancers who had experienced a dance-related injury that we categorized as "common," based on surveys of injuries among dancers (with back injuries excluded). One hundred and sixty-four dancers completed a tele- phone survey about their recovery after injury. Descriptive statistics, correlation, and linear regression were then used to identify factors associated with poor functional outcomes. Sixty-three percent of the participants had a full return to their pre-injury level. No variables were found to be significantly correlated (p < 0.05) with poorer outcomes by linear re- gression. However, there was a trend to- ward better outcomes when dancers were younger, their injuries were not chronic, and their recovery was not limited by fear. The three measurement tools were all highly correlated with one another (p = 0.000) and found to be useful determinants of functional return to dance. Given that there were few strongly correlated outcome factors, we concluded that poorer functional outcomes in dance resulted from a combination of many factors, including those of a psychosocial nature. We believe these results can be used to better advise dancers who are considering treatment options, provide better estimates of possible limitations and time needed to return to dance, and potentially promote easier recoveries and better functional outcomes. PMID- 29166987 TI - Turnout in Classical Dance: Is It Possible to Enhance the External Rotation of the Lower Limb by a Myofascial Manipulation? A Pilot Study. AB - Turnout in classical dance refers to the external rotation of the lower extremities so that the longitudinal axes of the feet form an angle of up to 180 degrees . To what extent a myofascial manipulation (myofascial release, MFR) could enhance this external rotation is as yet unknown. In this pilot study, 16 students of dance and 3 dance instructors were randomly assigned to an intervention group (IG; N = 10) and a group of controls (CG; N = 9). Isolated external hip rotation (EHR) and functional turnout (TO) were evaluated three times (pre-, post-, and follow-up measurement) using a plurimeter and Functional Footprints(r) rotation discs. In addition, subjectively perceived physical flexibility (PPF) was determined by means of a written survey. The interval between pre- and post-measurement and between post- and follow-up measurement was 4 weeks. Only the IG received four 20-minute MFR treatments of the lower limb at weekly intervals between pre- and post-measurement. In both the post-measurement (pre- versus post-: p = 0.038, d = 0.77) and the follow-up measurement (pre- versus follow-up: p < 0.001, d = 1.66) the IG showed a significantly improved isolated EHR of the right hip and a significantly increased PPF (pre- versus post : p = 0.047, d = 0.73; pre- versus follow-up: p = 0.012, d = 1.00). The left EHR as well as the right and left TO were not affected by the intervention. It was demonstrated that four sessions of MFR of the lower limb can induce an improvement in the isolated external hip rotation (right hip). The beneficial effects of the treatment regarding an improvement of functional turnout could not be entirely verified in this pilot study. However, the significant increase in the participants' subjective flexibility supports the promising trend in the objective parameters and emphasizes the need to undertake further research. PMID- 29166988 TI - External Focus of Attention Enhances Children's Learning of a Classical Ballet Pirouette. AB - The purpose of the present study was to investigate the influence of instructions promoting an external versus internal focus of attention on the learning of a specific balance task, the pirouette en dehors (from fourth position), in 10-year old novice ballet students. In addition, we sought to gain insight into learners' motivation and subjective learning experience as a function of different focus conditions. Thirty-eight children were randomly assigned to one of two groups. In the external focus (EF) group, participants were asked to focus on a spotting point on the wall in front of them for as long as possible. In the internal focus (IF) group, participants were asked to focus on the initial position of their head relative to the wall in front of them and on keeping it in that position for as long as possible. The task goal was to rotate as far as possible, and the dependent variable was the number of degrees rotated. All participants performed 15 practice trials of a (right) pirouette. Two days later, participants completed retention and transfer (left pirouette) tests without attentional focus reminders. After the practice phase, participants were asked what they thought about while practicing the pirouette and completed self-rating scales related to their perceived competence, effort, and sense of the importance of doing well. The EF group demonstrated superior performance relative to the IF group during practice, retention, and transfer phases. In addition, EF participants' responses indicated higher perceived competence and greater satisfaction with their performance, as well as greater importance of performing well. In contrast, IF participants reported more nervousness and fear of losing balance and not doing well. Overall, the findings demonstrate that external relative to internal focus instructions enhanced the students' learning of the pirouette en dehors and had positive motivational consequences. PMID- 29166992 TI - Use of Alum for Odor Reduction in Sludge and Biosolids from Different Wastewater Treatment Processes. AB - Applicability of alum addition to wastewater sludge and biosolids produced from different treatment processes was evaluated as a means of odor reduction. Four water resource recovery facilities (WRRFs) were chosen for this study: two used mesophilic anaerobic digestion and two used oxidation ditch processes. The experiments were conducted on a laboratory scale and in all cases the alum was added prior to dewatering. This is the first report of the application of alum for odor reduction in oxidation ditch processes. Alum addition was effective in reducing odors in anaerobically digested biosolids. Addition of 4% alum to anaerobically digested liquid biosolids prior to dewatering resulted in a 60% reduction in the peak odor concentration in the laboratory dewatered cake, relative to the control sample. Alum addition did not reduce odors in dewatered sludge from oxidation ditch processes. PMID- 29166989 TI - Use of a Patient-Specific Outcome Measure and a Movement Classification System to Guide Nonsurgical Management of a Circus Performer with Low Back Pain: A Case Report. AB - Low back pain (LBP) can be detrimental to the career of a circus arts performer, yet there is minimal population-specific literature to guide care. Moreover, reluctance to discontinue training and the need to resume end-range lumbar motion can impede the success of conservative care. The purpose of this case report is to describe the use of a patient-specific outcome measure and a movement classification system to structure a home exercise program (HEP) for an adolescent training to be a circus performer. The patient was a 16-year-old female with a 10-month history of LBP. A Movement System Impairment examination indicated that she had lower abdominal weakness, gluteal weakness, and hip flexors that were short and stiff; hence, extension and rotation were repeated patterns of lumbopelvic movement associated with her LBP symptoms. The patient was seen for 16 visits over 16 weeks. The HEP focused on minimizing lumbopelvic extension and rotation movements while improving abdominal and gluteal strength and hip flexor flexibility. Resumption of acrobatic activities was guided by the Patient-Specific Functional Scale. As measured by this scale, her difficulty with five functional and acrobatic activities decreased from 4/10 at initial evaluation to less than or equal to 1/10 by discharge. It is concluded that using an outcome measure to assess difficulty of activities chosen by the patient and education on how to avoid movement patterns associated with LBP symptoms can help facilitate return to performance. PMID- 29166993 TI - Aerobic Biodegradation of OCDD by P. Mendocina NSYSU: Effectiveness and Gene Inducement Studies. AB - The goals of this study were to assess the effectiveness of (1) enhancing octachlorinated dibenzo-p-dioxin (OCDD) biodegradation under aerobic conditions by Pseudomonas mendocina NSYSU (P. Mendocina NSYSU) with the addition of lecithin, and (2) inducing OCDD ring-cleavage genes by pentachlorophenol (PCP) and OCDD addition. P. Mendocina NSYSU could biodegrade OCDD via aerobic cometabolism and lecithin was used as a primary substrate. Approximately 74 and 67% of OCDD biodegradation was observed after 60 days of incubation with lecithin and glucose supplement, respectively. Lecithin was also used as the solubilization additive resulting in OCDD solubilization and enhanced bioavailability of OCDD to P. Mendocina NSYSU. Two intradiol and extradiol ring cleavage dioxygenase genes (Pmen_0474 and Pmen_2526) were identified from gene analyses. Gene concentration was significantly enhanced after the inducement by PCP and OCDD. Higher gene inducement efficiency was obtained using PCP as the inducer, and Pmen_2526 played a more important role in OCDD biodegradation. PMID- 29166995 TI - Single-Laboratory Validation of a Method for the Determination of Vitamin D3 in Dietary Supplements by Liquid Chromatography with Tandem Mass Spectrometry (LC MS/MS). AB - A single-laboratory validation (SLV) for the analysis of vitamin D3 was performed in four types of dietary supplements (capsules, soft gels, syrups, and tablets) using LC-MS/MS. Samples were treated by alkaline saponification for oil-based soft gels and utilized EDTA solution for capsules, syrups, and tablets prior to n hexane extraction. Vitamin D3 in sample extracts was separated on a reversed phase C18 column (100 * 2.1 mm, 2.7 MUm) using a mobile phase of a 95 + 5 (v/v) mixture of 5 mM ammonium formate in methanol containing 0.1% formic acid and 5 mM ammonium formate in 0.1% formic acid running at a flow rate of 0.2 mL/min. Vitamin D3 was confirmed by the presence of three fragment ions at m/z 107, 159, and 259 within a defined retention time window from the precursor ion at m/z 385. Quantitation was based on the peak area at m/z 367 to that of the internal standard (d3-vitamin D3) at m/z 370 with reference to the respective response ratios of the calibration standards. The linear response of vitamin D3 ranged from 0.10 to 6.29 mg/L and the correlation coefficient (r) of the six-point calibration curves was >0.999. Accuracy, in terms of the spiked recoveries from blank syrup and starch powder at three different concentration levels, was 101 103%. Precision, determined by two different analysts over a period of 5 weeks, ranged from 2.7 to 7.0% for the four preparations. The SLV demonstrates the present LC-MS/MS method is reliable and robust for the determination of vitamin D3 in the studied dietary supplements. Considering the attainment of satisfactory SLV results, further validation through intra-laboratory collaborative study is recommended. PMID- 29166994 TI - Biological Phosphorus Recovery: Review of Current Progress and Future Needs. AB - This review summarizes the main species of polyphosphate accumulating organisms (PAOs) and algae, illustrates their pathways and key enzymes, discusses biological phosphorous (P) recovery from dilute waters, and identifies research avenues to encourage adoption and implementation. Phylogenic analysis indicates that the Proteobacteria phylum plays an important role in enhanced biological phosphorus removal (EBPR). The use of meta-transcriptome analysis and single cell based techniques to help overcome the challenges associated with non-PAO competition was discussed. For algae capable of luxury phosphorus uptake, fundamental research is needed to illustrate the phosphorus regulation process and key proteins involved. Emerging technologies and processes have great potential to further advance phosphorus recovery, including combined PAO/algae reactors, bioelectrochemical systems, and biosorption by phosphorus binding proteins. As the paradigm shifts toward holistic resource recovery, research is needed to explore P+ recovery with other resources (e.g., metals from sludge), using a combination of biological and chemical approaches. PMID- 29166996 TI - Validation of the MicroSnap Coliform and E. coli Test System for Enumeration and Detection of Coliforms and E. coli in a Variety of Foods. AB - The MicroSnap Coliform and E. coli system was devised to give rapid enumeration and detection of coliforms and/or Escherichia coli strains in a sample of food within an 8 h working shift. The method measures beta-galactosidase and beta glucuronidase enzymes using novel bioluminogenic substrates which develop an output light signal proportional to the concentration of enzyme discovered. The assay uses two different phases to determine the enzyme concentration. The first phase is an enrichment of the sample in a nutrient-rich broth device at 37 +/- 0.5 degrees C. After 6 or 8 h, an aliquot is taken from the enrichment device and injected into the Coliform Detection Device, which is assayed in a luminometer after 10 min of incubation at 37 +/- 0.5 degrees C. Samples testing positive in the Coliform Detection Device can be subsequently assayed specifically for E. coli using the E. coli Detection Device. The relative light unit output from the detection device is proportional to the bacterial concentration when the incubation was initiated, which is proportional to the contamination level in the matrix being assessed. The MicroSnap Coliform and E. coli system was evaluated for both quantitative and qualitative analysis of coliforms and E. coli in a variety of foods. Three different luminometers were used in the analysis, each of which has different functionalities and different sensitivities. The MicroSnap method showed good correlation with the appropriate corresponding reference method for enumeration of coliforms and E. coli. A statistically significant difference was seen in detection of E. coli in milk, as reported by the independent laboratory. The reference method reported higher mean Log10 CFU counts than the MicroSnap method; however, no significant differences were seen between the MicroSnap system and reference methods for any of the other matrixes. Inclusivity testing was conducted on 25 different non-E. coli coliforms and 25 different E. coli strains, and exclusivity testing was conducted on 30 different species of nontarget organisms. Two E. coli strains were not detected in the Coliform Detection Device after 8 h on one of the instruments. All other inclusivity strains tested were detected after 8 h of incubation. None of the exclusivity strains were detected. The lot-to-lot and kit stability studies showed no statistical differences between lots or over the term of the shelf life. Robustness studies indicate that the timing of incubation for the detection phase is critical for correct system functioning.

AB - The Thermo ScientificTM SureTectTM Listeria species Assay is a new real-time PCR assay for the detection of all species of Listeria in food and environmental samples. This validation study was conducted using the AOAC Research Institute (RI) Performance Tested MethodsSM program to validate the SureTect Listeria species Assay in comparison to the reference method detailed in International Organization for Standardization 11290-1:1996 including amendment 1:2004 in a variety of foods plus plastic and stainless steel. The food matrixes validated were smoked salmon, processed cheese, fresh bagged spinach, cantaloupe, cooked prawns, cooked sliced turkey meat, cooked sliced ham, salami, pork frankfurters, and raw ground beef. All matrixes were tested by Thermo Fisher Scientific, Microbiology Division, Basingstoke, UK. In addition, three matrixes (pork frankfurters, fresh bagged spinach, and stainless steel surface samples) were analyzed independently as part of the AOAC-RI-controlled independent laboratory study by the University of Guelph, Canada. Using probability of detection statistical analysis, a significant difference in favour of the SureTect assay was demonstrated between the SureTect and reference method for high level spiked samples of pork frankfurters, smoked salmon, cooked prawns, stainless steel, and low-spiked samples of salami. For all other matrixes, no significant difference was seen between the two methods during the study. Inclusivity testing was conducted with 68 different isolates of Listeria species, all of which were detected by the SureTect Listeria species Assay. None of the 33 exclusivity isolates were detected by the SureTect Listeria species Assay. Ruggedness testing was conducted to evaluate the performance of the assay with specific method deviations outside of the recommended parameters open to variation, which demonstrated that the assay gave reliable performance. Accelerated stability testing was additionally conducted, validating the assay shelf life. PMID- 29166999 TI - Evaluation of the Thermo ScientificTM SureTectTM Salmonella species Assay.

PMID- 29167000 TI - [Study on Genetype in Lung Squamous Carcinoma by High-throughput of ?Transcriptome Sequence]. AB - BACKGROUND: Recently, there is no effective targeted drug for to the lung squamous carcinoma, the targeted drug for the adenocarcinoma does not benefit for the patients with squamous lung cancer, and researchers have known less targets for this type of patients. The main study herein is to screen and identify the specific key genes for the lung squamous carcinoma that will provide potential novel targets to describe pathogenesis of lung cancer. METHODS: Transcript sequence was used to detect the five pairs lung squamous carcinoma and normal lung tissues and bioinformatics was performed to investigate the differential coding genes between them and quantitative PCR was done to validate the key genes expression in lung cancer cell lines. RESULTS: The results of transcriptome sequence showed that 534 genes were up-regulated in the tumor tissues compared with the corresponding normal tissues. The top ten increased genes in the tumors were GAGE12J, SPRR3, PRAME, SPRR1A, SPRR2E, MAGEA3, SPRR1B, IL36G and TMPRSS11D. Next, we identified expression of SPRR family in lung cancer cell lines H520, GLC82, A549, H1299 and PC9. And we found higher expression of SPRR family genes in H1299 cells which metastasized to the lymph node. CONCLUSIONS: SPRR family genes are identified to be highly expressed in the lung squamous carcinoma by high throughput transcript sequencing. This SPRR family genes are associated with lymph node metastasis that provide novel idea for lung cancer therapy.?. PMID- 29167001 TI - [Association between the ALK Gene Status and the Efficacy of First-line ?Pemetrexed Chemotherapy in Patients with Advanced Lung Adenocarcinoma]. AB - BACKGROUND: Anaplastic lymphoma kinase (ALK) is one of the major driver genes of non-small cell lung cancer (NSCLC). Several studies have shown that the efficacy of pemetrexed in ALK-positive lung cancer is controversial. The aim of this study is to explore the efficacy of pemetrexed-based chemotherapy in patients with ALK positive and negative lung adenocarcinoma. METHODS: The clinical data of 98 cases of epidermal growth factor receptor (EGFR), kirsten rat sarcoma viral oncogene (KRAS), V-rafmurine sarcoma viral oncogene homolog B1 (BRAF)-negative patients with advanced lung adenocarcinoma patients who diagnosed by histopathology from January 2015 to April 2016 in the First Affiliated Hospital of Zhengzhou University were collected. The relationships between ALK gene status, clinical characteristics and response and progression-free survival (PFS) were analyzed. RESULTS: All of the 98 patients' ALK status were determined. ALK gene fracture fusion occured in 34 cases (34.7%), no fracture fusion in 64 cases (65.3%). All patients underwent first-line pemetrexed and platinum-based chemotherapy, the objective response rate (ORR) was 21.4% and the disease control rate (DCR) was 84.7%. The ORR and DCR of patients with ALK fracture fusion were higher than those without fracture fusion (41.2% vs 10.9%, chi2=23.389, P<0.001; 91.2% vs 81.3%, chi2=4.153, P=0.042), the difference was statistically significant. ALK gene status was not related to age, gender, smoking history and clinical stage. The median PFS of ALK-positive lung adenocarcinoma was 7.1 months (95%CI: 6.1 8.1) and negative was 4.7 months (95%CI: 3.818-5.582), and the difference was statistically significant (chi2=13.269, P<0.001). Cox multivariate analysis indicates that PFS of pemetrexed combined with platinum chemotherapy was independent of gender, age, smoking, staging and platinum. ALK gene fracture fusion is an independent factor affecting PFS (HR=0.392, 95%CI: 0.243-0.634, P<0.001). CONCLUSIONS: ALK-positive lung adenocarcinoma patients with first-line pemetrexed-based chemotherapy have greater clinical benefit than ALK-negative patients. PMID- 29167002 TI - [Efficacy and Toxicity of Metronomic Oral Vinorelbinen in Advanced Non-small Cell Lung Cancer after Failure to Multiple-lines Treatments]. AB - BACKGROUND: The development of new treatments beyond first-line in metastatic non small cell lung cancer (NSCLC) contributed to the increase in overall survival. Metronomic chemotherapy involves several mechanisms of anti-tumor with less toxicity. Oral vinorelbine has paved the way for innovative treatment strategies through metronomic regimens. Therefore, this study assessed the efficacy and safety of metronomic oral vinorelbinen in advanced NSCLC after failure to multiple-lines treatments. METHODS: Our retrospective study enrolled 26 patients who received metronomic oral vinorelbinen. Survival factors were evaluated by univariate regression analysis. RESULTS: The median follow-up time was 4 months (range 2-12). The median number of treatment cycles was 2 (range 1-8). No patient achieved complete remission, 2 cases (8%) partial remission, 11 cases (42%) stable disease, 13 cases (50%) progression disease. Overall response rate was 8% and disease control rate was 50%. The median progression-free survival (PFS) was 2 months. In univariate analysis, patients with performance status (PS)=1 had a statistically significantly longer PFS than patients with PS=2. Gender, age, smoking status and histology were not prognostic factors according to PFS. Treatment was well tolerated with rare serious toxicity. No grade 4 adverse events (AEs) or occurrences of intolerable toxicity were observed. There was no treatment-related death and none of the study patients required hospitalization for treatment-related adverse events. CONCLUSIONS: Metronomic oral vinorelbinen is effective in advanced NSCLC after the failure of multiple lines treatments with an acceptable AE profile, especially in patients with high PS.?. PMID- 29167003 TI - [Prognostic Analysis of Patients with Advanced Non-small Cell Lung Cancer ?in Different Genotypes]. AB - BACKGROUND: Non-small cell lung cancer (NSCLC) has been transformed from the treatment according to histological type to genotype treatment model. The epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) genes are the most important drivers in lung cancer. The aim of this study is to explore the clinical characteristics and prognostic factors of patients with advanced NSCLC with different genotypes. METHODS: We retrospectively reviewed the clinical data of 553 advanced NSCLC patients with EGFR mutations and ALK positive who were hospitalized in the Beijing Chest Hospital from July 2004 to December 2015, and the independent prognostic factors of patients were analyzed by Cox proportional hazards regression model. RESULTS: The clinical data of 553 patients (227 with EGFR mutations, 58 with ALK positive, 2 with EGFR and ALK co-mutation and 266 with wild-type) with advanced NSCLC were enrolled in this study. The median survival time of 227 patients with EGFR mutations was 28.7 mo (95%CI: 22.160-35.240), and the performance status (PS) score (0-1) (HR=4.451; 95%CI: 2.112-9.382; P<0.001) and EGFR-tyrosine kinase inhibitors (TKIs) targeted therapy (HR=2.785; 95%CI: 1.871-4.145; P<0.001) were the independent prognostic factors for the survival of patients harboring EGFR mutations. The median survival time of 58 patients with ALK positive was 15.5 mo (95%CI: 10.991-20.009), and treatment with crizotinib (P=0.022) was the independent influence factor for the survival of ALK positive patients. The median survival time of 266 patients with wild-type was 12.1 mo (95%CI: 10.660-13.540), and the PS score (0-1) (HR=2.313; 95%CI: 1.380-3.877; P=0.001) and treatment with chemotherapy (HR=1.911; 95%CI: 1.396-2.616; P<0.001) were the independent prognostic factors for the survival of wild-type patients CONCLUSIONS: The prognosis of patients with advanced NSCLC is associated with genetic mutation, and targeted therapy has a improvement on survival for patients with EGFR mutations or ALK rearrangement. PMID- 29167004 TI - [A Programmed Procedure of Prosthetic Reconstruction of the Superior Vena Cava ?for Thoracic Tumors via Median Thoracotomy]. AB - BACKGROUND: The involvement of superior vena cava is a common condition in locally advanced thoracic tumors. Patients may benefit from the high risk operation. This study proposed a programmed procedure to optimize surgical techniques, which can facilitate the safety of operation via median thoracotomy. METHODS: A total of 35 patients with thoracic disease involved superior vena cava underwent prosthetic vascular reconstruction via median thoracotomy. All patients were confirmed locally advanced without distant metastasis including 16 pulmonary neoplasm and 19 mediastinal disease. The operations proceed from left to right with one direction manner. The initial part of the left innominate vein was dissected, then cut off, so as to lift tumor, the pericardium was opened, and the left innominate vein and the right artrium were bridged with prosthetic vascular. The proximal end of the superior vena cava which not invaded was dissected and the tumor was pulled to the caudal side, the right mediastinal pleura was opened and the right inner mammary vascular was ligated and the right innominate vein was fully revealed. Stretch the tumor to left top, cut azygos vein on above the hilum, then block the right innominate vein and superior vena cava, removed involved part of blood vessels, the right innominate vein and superior vena cava was connected with prosthetic vascular. With these procedures the superior vena cava was reconstructed completely. RESULTS: The operation was completed successfully in all cases. Postoperative complications included 6 cases with arrhythmia, 5 cases with hypoxemia, 1 case with myasthenia crisis, 1 case with cardiac hernia, and 2 cases with fungal infection. 2 patients died of myocardial infarction and lung infection respectively with a mortality rate of 5.12%. The remaining 33 cases were discharged successfully. The average postoperative hospital stay was 15 days. Of the 10 patients with superior vena cava syndrome preoperatively, 8 patients had symptoms relief except 2 cases with intraoperative intravascular thrombosis. CONCLUSIONS: We recommended the programmed procedure of prosthetic reconstruction of the superior vena cava, standardize the details of treatment, and minimize the risk during operation. The safe surgical procedures of this group of cases confirm this practice. PMID- 29167005 TI - [Distribution and Clinical Significance of CTLA-4, PD-1 and PD-L1 in Peripheral Blood of Patients with Small Cell Lung Cancer]. AB - BACKGROUND: The aim of this study is to explore cytotoxic T lymphocyte associated antigen 4 (CTLA-4), programmed death 1 (PD-1) and programmed death ligand 1 (PD L1) distribution and clinical value in liquid biopsy (such as blood) of small cell lung cancer (SCLC) patients. METHODS: A total of 60 healthy and 290 chemotherapy-naive patients with SCLC were recruited. Venous blood samples were collected prior to chemotherapy (baseline) and after the second cycle of chemotherapy (2nd cycle), and flow cytometry was used to analyze the level of CTLA-4, PD-1 or PD-L1 with or without CD3, CD4, CD8 or CD25. Immunocytochemical method was used to detect PD-L1 expression in SCLC cell line H446. RESULTS: Cells of CTLA-4+ and PD-1+ in SCLC peripheral blood were (1.56+/-1.24)% and (8.07+/ 3.97)%; there is no significant difference between CD3+CTLA-4+ and CD4+CTLA-4+, (4.87+/-5.18)% and (3.85+/-2.60)%, but show lower expression than CD3+PD-1+ and CD4+PD-1+ (26.63+/-9.04)% and (20.79+/-9.41)%, respectively. However, the level of CD4+CD25+CTLA-4+ cells were remarkably higher in SCLC than that in control, (7.09+/-5.09)% vs (1.91+/-1.27)%, P<0.001 and CD8+PD-1+ cells were less in SCLC than that in control, (11.47+/-5.85)% vs (22.56+/-4.21)%, P<0.001, both of which were not associated with age, sex, smoke or disease stage. Level of CD4+CD25+CTLA 4+ cells and CD8+PD-1+ cells was dropped (5.11+/-2.60)% vs (6.94+/-4.91)% and (8.74+/-3.39)% vs (11.48+/-5.91)% after 2nd cycle compare to that at baseline (P<0.000,1). Neither the level of CD4+CD25+CTLA-4+ nor CD8+PD-1+ cells before or after treatment was related to progression-free disease or overall survival of patients. Although PD-L1 was highly expressed in H446 cell cytoplasm and membrane, it was rarely found in peripheral blood. CONCLUSIONS: The data we presented here showed that CTLA-4 was highly expressed in regulatory T cells and PD-1 decreased in CD8+ T cells in peripheral blood of SCLC patients, suggesting their unique mechanisms involved in immune regulation. CD4+CD25+CTLA-4+ level changed after treatment implies its potential role in predicting treatment efficacy.?. PMID- 29167006 TI - [Efficacy and Survival Analysis of Apatinib in Patients with Advanced Nonsquamous Non-small Cell Lung Cancer after Failure of First-line Treatment]. AB - BACKGROUND: The efficacy of second or third-line chemotherapy in advanced non small cell lung cancer (NSCLC) patients is low. The use of targeted drugs brings survival benefit for some patients. Apatinib, as a novel small molecule antiangiogenic drug, has demonstrated satisfactory anticancer activity across a broad range of malignancies. The aim of this study is to evaluate the efficacy and safety of apatinib in patients with advanced NSCLC after first-line treatment failure. METHODS: A retrospective study of 128 patients was conducted to evaluate the safety, short-term efficacy and survival status with different regimens. Kaplan-Meier method and Cox regression model were used for analysis. RESULTS: Compared with chemotherapy alone, the median progression free survival (PFS) in apatinib monotherapy, chemotherapy alone and apatinib combined with chemotherapy were 3.0 (P=0.381), 3.7 and 6.0 months (P<0.001), respectively. The median overall survival (OS) were 6.0 (P=0.494), 6.5 and 9.0 months (P=0.001), respectively. The incidence of adverse events in grades 3-4 were 18.5%, 15.8% and 16.0%, respectively (P=0.947). Different treatment regimens (P=0.018) and performance status (PS)(P<0.001) were the independent factors of PFS. The smoking history (P=0.014), treatment regimens (P=0.002) and PS (P<0.001) were independent influencing factors of OS. CONCLUSIONS: Apatinib has a good security. After first line treatment failure of lung cancer, chemotherapy combined with apatinib in second or third-line is beneficial in PFS and OS when compared with chemotherapy alone. But when making comparison between apatinib monotherapy and chemotherapy alone, there is no significant difference in PFS and OS. Patients who never smoke or has a better PS or use combination therapy have longer survival time.?. PMID- 29167007 TI - [MicroRNA-26a and Tumor].

PMID- 29167008 TI - [New Progress in the Relationship between Immune Cells, PD-1 ?in Tumor Microenvironment and the Efficacy of EGFR-TKIs]. AB - In recent years, targeted therapy of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKIs) is the leading treatment modality for patients with advanced non-small cell lung cancer (NSCLC) and EGFR gene mutation. However, with the prolongation of the medication time, most of the patients appeared drug resistance. Tumor microenvironment is the internal environment for the survival and development of tumor cells. The immune response which mediated by immune cells, like regulatory T (Treg), dendritic cells, macrophages, fibroblasts, etc. And the programmed cell death receptor 1 (PD-1) with its ligand PD-1L/PD-2L may participate in the drug resistance of EGFR-TKIs. This review will elaborate the possible mechanism of the interaction of immune cells on EGFR-TKIs in the tumor microenvironment, in order to seek new targets, and further improve the anti tumor efficacy and prolong the effective time of EGFR-TKIs.

AB - We present a case of two-year old boy with solitary atypical adenomatous hyperplasia (AAH) in extralobar sequestration (ELS), which was misdiagnosed as diaphragmatic hernia before surgery. Review of AAH and pulmonary sequestration (PS) revealed that the present case is the youngest of solitary AAH and also the first report of solitary AAH arising in ELS without a primary lung cancer. In a sense, the present case firstly supports the hypothesis that ELS may be an underlying cancer predisposition syndrome, so aggressive surgical therapy should be recommended for ELS.

AB - Programmed death 1 (PD-1) and programmed death 1 ligand (PD-L1) pathway is a key mechanism of immune regulation, and its abnormal activation in tumor tissues suggests that PD-1/PD-L1 pathway may participate in the regulation of tumor immune escape. Driver gene mutation which is known as a key factor in the tumorigenesis of non-small cell lung cancer (NSCLC), was also reported to play a important role in the process of tumor immune escape. It indicates that there is an interaction between driver gene and PD-1/PD-L1 pathway. The purpose of this paper is to review the relationship between PD-1/PD-L1 pathway and lung cancer driver gene, such as epidermal growth factor receptor (EGFR), Kirsten rate sarcoma viral oncogene homolog (KRAS) and echinoderm microtubuleassociated protein-like 4 - anaplastic lymphoma kinase (EML4-ALK) and to summarize the role of lung cancer driver gene and PD-1/PD-L1 pathway interaction in the tumorigenesis and progression of NSCLC.

PMID- 29167011 TI - [Four Cases Report on Primary Lung Adenoid Cystic Carcinoma]. AB - BACKGROUND: Lung adenoid cystic carcinoma is a kind of rare lung cancer. Diagnosis and treatment is not enough understandable for them. We collected and analyzed 4 cases of lung adenoid cystic carcinoma for broadening the sight of this disease. METHODS: Retrospectively analysed the 4 cases we collected from Hunan Cancer Hospital Between January 2012 and December 2016. We depicted the pathology, immunohistochemical, epidermal growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) arrangement in these cases. And the methods of the diagnosis and treatment were analyzed. RESULTS: Lung adenoid cystic carcinoma is usually located in the airway, EGFR mutation and ALK arrangement is rare in this disease. Generally the metastasis of the lung cancer occurred in the advanced stage. The prognosis is good if the mass could be resected completely. CONCLUSIONS: Diagnosis of the lung adenoid cystic carcinoma depends on pathological experiments, surgery is the main treatment in the early stage, radiotherapy and chemotherapy is an advisable therapy in the advanced stage. And the prognosis of this kind of lung cancer is better than small cell lung cancer and non-small cell lung cancer.

AB - In order to mimic the maternal oviductal environment, we evaluated the effect of oviductal fluid (OF) and/or uterine fluid (UF) supplementation on in vitro embryo development and quality. In vitro-produced zygotes were cultured with 1.25% OF from Day 1 to Day 4 after insemination (OF group), 1.25% OF from Day 1 to Day 4 followed by 1.25% UF from Day 4 to Day 9 (OF+UF group) or 1.25% UF only from Day 4 to Day 9 (UF group). Control groups were cultured in the presence of synthetic oviduct fluid (SOF) supplemented with 3mgmL-1 bovine serum albumin (BSA) or 5% fetal calf serum (FCS). Supplementation of the culture medium with OF and/or UF (both at 1.25%) supported embryo development (Day 9 blastocyst rate 28.2-30.6%). At 72h after vitrification-warming, the survival of blastocysts from the OF and OF+UF groups was similar to that of blastocysts in the SOF+BSA group (61.0+/-5.7% and 62.8+/-6.4% vs 64.8+/-6.4% respectively), but significantly higher than that of blastocysts from the SOF+FCS group (31.6+/-4.9%; P<0.001). Blastocysts from the OF group exhibited upregulation of epigenetic genes (i.e. DNA methyltransferase 3alpha (DNMT3A) and insulin-like growth factor 2 receptor (IGF2R)), compared with expression in the SOF+FCS group (P<0.05). Whereas those from OF+UF and UF groups exhibited downregulation of oxidative stress genes compared to SOF+BSA and OF groups for glutathione peroxidase (GPX1) and to SOF+FCS, SOF+BSA and OF groups for chloride intracellular channel 1 (CLIC1) (P<0.05). In addition, accumulation of reactive oxygen species was lower in blastocysts from the OF, OF+UF and UF groups. In conclusion, the use of low concentrations of OF and UF in in vitro serum-free culture supports embryo development, with OF providing a better control of embryo methylation, whereas UF may have antioxidant activity. PMID- 29167014 TI - The effect of age and body composition on body mass estimation of males using the stature/bi-iliac method. AB - The stature/bi-iliac breadth method provides reasonably precise, skeletal frame size (SFS) based body mass (BM) estimations across adults as a whole. In this study, we examine the potential effects of age changes in anthropometric dimensions on the estimation accuracy of SFS-based body mass estimation. We use anthropometric data from the literature and our own skeletal data from two osteological collections to study effects of age on stature, bi-iliac breadth, body mass, and body composition, as they are major components behind body size and body size estimations. We focus on males, as relevant longitudinal data are based on male study samples. As a general rule, lean body mass (LBM) increases through adolescence and early adulthood until people are aged in their 30s or 40s, and starts to decline in the late 40s or early 50s. Fat mass (FM) tends to increase until the mid-50s and declines thereafter, but in more mobile traditional societies it may decline throughout adult life. Because BM is the sum of LBM and FM, it exhibits a curvilinear age-related pattern in all societies. Skeletal frame size is based on stature and bi-iliac breadth, and both of those dimensions are affected by age. Skeletal frame size based body mass estimation tends to increase throughout adult life in both skeletal and anthropometric samples because an age-related increase in bi-iliac breadth more than compensates for an age-related stature decline commencing in the 30s or 40s. Combined with the above-mentioned curvilinear BM change, this results in curvilinear estimation bias. However, for simulations involving low to moderate percent body fat, the stature/bi-iliac method works well in predicting body mass in younger and middle aged adults. Such conditions are likely to have applied to most human paleontological and archaeological samples. PMID- 29167015 TI - Quantification of fat infiltration in the sacroiliac joints with ankylosing spondylitis using IDEAL sequence. AB - AIM: To quantitatively assess fat infiltration in the sacroiliac joints (SIJs) of patients with ankylosing spondylitis (AS) by measuring the fat/water signal ratios of periarticular bone marrow with iterative decomposition of water and fat with echo asymmetry and least square estimation (IDEAL). MATERIALS AND METHODS: Routine SIJ magnetic resonance imaging (MRI) and IDEAL were performed on 40 patients with AS and 30 healthy subjects. The fat infiltration regions (FIRs) and normal-appearing regions (NARs) of patients were measured based on the fat/water signal intensity on IDEAL. RESULTS: AS patients had higher fat/water signal ratios on FIRs and NARs (65.4-85.4%, p<0.05, and 44.1-70.7%, p<0.05, respectively) compared to healthy controls (38.3-43.3%). After treatment, the fat/water signal ratios of FIRs and NARs decreased (42.1-53.7% and 41.5-50.3%, respectively), but they remained higher than in the healthy controls (p<0.05). The fat infiltration was detected more effectively with a fat fraction map of the IDEAL sequence (95%) than other sequences, including the T1-weighted sequence (65%), and the fat/water signal ratios of the sacrum and ilium between the left and right sides of SIJs were approximately the same. CONCLUSION: The findings of this study suggest that IDEAL may be useful as a quantitative and objective method for evaluating the fat infiltration in the periarticular bone marrow of SIJs with AS; additionally, the sensitivity of IDEAL is better than that of routine sequences in detecting micro-fat infiltration of SIJs, and IDEAL can be used to quantitatively measure the adipose content and monitor patient follow-up after AS treatment.

PMID- 29167018 TI - Impact of statin use on the prognosis of patients with hepatocellular carcinoma undergoing liver resection: a subgroup analysis of patients without chronic hepatitis viral infection. AB - BACKGROUND: Statins have been reported to reduce the risk of hepatocellular carcinoma (HCC). The effect of perioperative statin use on the prognosis of HCC patients undergoing liver resection remains unclear. METHODS: We retrospectively analyzed 643 patients who underwent curative liver resection for HCC. Patients negative for hepatitis B surface antigen and hepatitis C antibody were classified as the non-B non-C HCC subgroup (n = 204). Perioperative statin users were defined as patients preoperatively receiving statin medications and maintaining > 28 cumulative defined daily doses after liver resection. The recurrence-free survival (RFS) and overall survival (OS) according to statin use were analyzed in the overall HCC cohort or in the non-B non-C HCC subgroup. RESULTS: Among a total of 643 (HCC) patients, 43 patients (6.7%) received perioperative statin medications. In statin users, the proportion of non-B non-C HCC patients was significantly higher than in nonstatin users. Statin users had a high prevalence of obesity and diabetes, as well as dyslipidemia. The liver function of statin users was better than that of nonstatin users. The multivariate survival analysis revealed that use of statins was significantly associated with improvement of RFS (hazard ratio [HR], .42; 95% confidence interval [CI], 0.25-0.71; P = .001), but not with OS (HR, 0.62; 95% CI, 0.30-1.27; P = .19). In the subgroup analysis of the non-B non-C HCC cohort, statin use was significantly associated with improvement of RFS (HR, 0.47; 95% CI, 0.22-0.99; P = .04). CONCLUSION: Perioperative statin use was associated with an improvement of RFS in HCC patients undergoing curative liver resection. PMID- 29167019 TI - Reassessing the utility of CT angiograms in penetrating injuries to the extremities. AB - BACKGROUND: Computed tomography angiography has become routine in the management of penetrating trauma to the extremity. Our objective was to evaluate the efficacy of physical examination findings compared with computed tomography angiography for detection of clinically significant vascular injuries associated with penetrating trauma to the extremity. METHODS: This was a retrospective chart review of patients presenting to a single level 1 trauma center from January 2013 June 2016. Patients with penetrating trauma to the extremity and no hard signs of vascular injury were included. Physical examination and computed tomography angiography findings were analyzed, with particular focus given to missed injuries. RESULTS: We identified 393 patients with penetrating trauma to the extremity without hard signs of vascular injury. Computed tomography angiography was performed in 114 patients (29%). Four patients with distal pulses documented on their initial trauma surveys were found to have vascular injuries on computed tomography angiography, although 3 of these injuries were identified on repeat physical examination. One additional patient had a delayed presentation of a pseudoaneurysm. No mortality or limb loss resulted from these injuries. Total hospital charges for computed tomography angiography amounted to over $700,000. CONCLUSION: Patients with penetrating trauma to the extremity and no hard signs of vascular injury do not require computed tomography angiography for identification of clinically relevant vascular injuries that require emergent operative repair. Serial physical examination appears to provide accurate detection of vascular injury requiring procedural intervention. PMID- 29167020 TI - Laboratory validation of a point velocity probe for measuring horizontal flow from any direction. AB - The point-velocity probe (PVP) quantifies groundwater speed and flow direction, i.e., velocity, at the centimeter scale. The first probe designs required that the flow direction be known a priori, within about 100 degrees in order to position the probe during installation. This study introduces and assesses a '360 degrees PVP' that measures flow from any direction without foreknowledge of the groundwater velocity. In tests conducted in a Nested Storage Tank (NeST) aquifer simulator packed with sand, PVP-measured velocities matched expected velocities within +/-9 degrees in direction and +/-15% in magnitude, on average, consistent with previously reported PVP performances in laboratory studies. In tests involving 17 repacked NeSTs, the measured and expected velocities were within +/ 30 degrees and +/-30% on average, illustrating the sensitivity of flow to porous medium packing, and the probes' ability to sense these changes; the porosity was found to vary considerably between packings i.e., n=0.34+/-0.2. For flow directions between 0 degrees and 80 degrees of an injection port, the experimental error on velocity magnitude was within the ranges reported above. At higher flow angles, experimental sources of error contributed to greater uncertainties. Fortunately, in these cases there were always alternative injection ports (with lower angles to flow) that could be used to circumvent any biases. At low experimental flow angles (<10 degrees ) the calculated values tended to overestimate the actual flow angles. Fortunately, these cases were identifiable by the detection of tracer at detectors on either side of the active injection port. In several tests designed with an expected flow direction of 0 degrees , averaging the calculated directions from each side of the injection port resulted in improved matches to the expected flow direction. PMID- 29167021 TI - Diffuse large B-cell lymphoma. AB - Diffuse large B cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma worldwide, representing approximately 30-40% of all cases in different geographic regions. Patients most often present with a rapidly growing tumour mass in single or multiple, nodal or extranodal sites. The most common type of DLBCL, designated as not otherwise specified, represents 80-85% of all cases and is the focus of this review. There are also rare types of lymphoma composed of large B-cells, in aggregate about 15-20% of all neoplasms that are sufficiently distinctive to recognise separately. DLBCL not otherwise specified (referred to henceforth as DLBCL) is a heterogeneous entity in terms of clinical presentation, genetic findings, response to therapy, and prognosis. A major advance was the application of gene expression profiling (GEP) to the study of DLBCL which further clarified this heterogeneity and provided a rationale for subdividing cases into groups. The most popular system divides cases of DLBCL according to cell-of-origin into germinal centre B-cell like (GCB) and activated B-cell like (ABC) subtypes, with about 10-15% of cases being unclassifiable. Patients with the GCB subtype usually have better prognosis than patients with the ABC subtype. Although cell-of-origin is useful for predicting outcome, the GCB and ABC subtypes remain heterogeneous, with better and worse prognostic subsets within each group. Next generation sequencing (NGS) analysis of DLBCL has facilitated global identification of numerous and diverse genetic abnormalities in these neoplasms and has shown that GCB and ABC tumours have different mutation profiles. Although the therapy of patients with DLBCL is an active area of research, the current 5-year overall survival rate is 60-70% using standard-of care frontline therapy. A precision medicine approach for the design of new therapies based on molecular findings in DLBCL is likely the best path forward. As pathologists, our role has expanded beyond diagnosis. We must perform a complete work-up of DLBCL cases. In addition to our traditional role in establishing the diagnosis, we need to analyse markers that provide information regarding prognosis and potential therapeutic targets. We also must ensure that adequate tissue is triaged for molecular studies which are essential for designing therapy regimens, particularly in the setting of disease relapse.

PMID- 29167023 TI - Underlying mechanisms of mistreatment in the surgical learning environment: A thematic analysis of medical student perceptions. AB - BACKGROUND: Medical students experience more psychological distress than the general population. One contributing factor is mistreatment. This study aims to understand the mechanisms of mistreatment as perceived by medical students. METHODS: Students completed anonymous surveys during the first and last didactic session of their surgery clerkship in which they defined and gave examples of mistreatment. Team-based thematic analysis was performed on responses. RESULTS: Between January 2014 and June 2016, 240 students participated in the surgery clerkship. Eighty-nine percent of students completed a survey. Themes observed included (1) Obstruction of Students' Learning, (2) Exploitation of Student Vulnerability, (3) Exclusion from the Medical Team, and (4) Contextual Amplifiers of Mistreatment Severity. CONCLUSION: The themes observed in this study improve our understanding of the students' perspective on mistreatment as it relates to their role in the clinical learning context, which can serve as a starting point for interventions that ultimately improve students' experiences in the clinical setting. PMID- 29167024 TI - Evolving treatment of necrotizing pancreatitis. AB - BACKGROUND: Over the past decade, the treatment of necrotizing pancreatitis (NP) has incorporated greater use of minimally invasive techniques, including percutaneous drainage and endoscopic debridement. No study has yet compared outcomes of patients treated with all available techniques. We sought to evaluate the evolution of NP treatment at our high volume pancreas center. We hypothesized that minimally invasive techniques (medical only, percutaneous, and endoscopic) were used more frequently in later years. METHODS: Treatment strategy of NP patients at a single academic medical center between 2005 and 2014 was reviewed. Definitive management of pancreatic necrosis was categorized as: 1) medical treatment only; 2) surgical only; 3) percutaneous (interventional radiology - IR) only; 4) endoscopic only; and 5) combination (Surgery +/- IR +/- Endoscopy). RESULTS: 526 NP patients included biliary (45%), alcoholic (17%), and idiopathic (20%) etiology. Select patients were managed exclusively by medical, IR, or endoscopic treatment; use of these therapies remained relatively consistent over time. A combination of therapies was used in about 30% of patients. Over time, the percentage of NP patients managed without operation increased from 28% to 41%. 247 (47%) of patients had operation as the only NP treatment; an additional 143 (27%) required surgery as part of a multidisciplinary management. CONCLUSION: Select NP patients may be managed exclusively by medical, IR, or endoscopic treatment. Combination treatment is necessary in many NP patients, and surgical treatment continues to play an important role in the definitive therapy of necrotizing pancreatitis patients. PMID- 29167025 TI - Decrease of galectin-3 in keratinocytes: A potential diagnostic marker and a critical contributor to the pathogenesis of psoriasis. AB - Psoriasis-specific proteins dysregulated in keratinocytes and involved in the pathophysiological process of psoriasis remains elusive. We report here that epidermal galectin-3 expression is significantly downregulated in lesional skin, but not in non-lesional skin in psoriasis patients, nor in a group of diseases known as psoriasiform dermatitis clinically and histologically similar to psoriasis. The deficiency of epidermal galectin-3 is sufficient to promote development of psoriatic lesions, as evidenced by more severe skin inflammation in galectin-3 knockout (gal3-/-) mice, compared to wild-type mice, after imiquimod treatment, and in skin from gal3-/- mice grafted onto wildtype mice. The development of psoriatic-like lesions is attributable to 1) the spontaneously tuning up of psoriasis signatures in keratinocytes through JNK pathway; and 2) neutrophil accumulation caused by the enhanced leukocyte-recruiting capacity associated with overexpression of S100A7-9 and CXCL-1, 8 in keratinocytes with impaired galectin-3 expression. Psoriasis-like skin inflammation is significantly improved in gal-3-/- mice both by inhibition of neutrophils accumulation with a selective CXCR2 antagonist of SB225002, and by intracutaneous injection of recombinant galectin-3. Overall, these findings offer promising galectin-3 related diagnostic and therapeutic resolutions of psoriasis. PMID- 29167026 TI - Safety of Moderate Hypothermia With Antegrade Cerebral Perfusion in Total Aortic Arch Replacement. AB - BACKGROUND: Total aortic arch replacement (TOTAL) is a complicated operation and has traditionally required deep hypothermic circulatory arrest. In this study, the impact of moderate hypothermic circulatory arrest (MHCA) and antegrade cerebral perfusion (ACP) for TOTAL were examined. METHODS: The ARCH International aortic database was queried and 3,265 patients undergoing TOTAL using ACP were identified. Patients were divided into groups based on lowest cooling temperature: MHCA (20 degrees to 28 degrees C) or deep hypothermia (DHCA) (12 degrees to 20 degrees C). Propensity-matched scoring using 15 variables was used in 669 matched pairs. Multivariable analyses were performed. RESULTS: In the unmatched cohort, more patients underwent MHCA (2,586; 79.2%) who were also younger (p < 0.001) and more frequently underwent emergent operations (p < 0.001) than DHCA patients. For the propensity-matched patients, there were significant differences in cardiopulmonary bypass (CPB) time (MHCA 200 minutes versus DHCA 243 minutes, p < 0.001), aortic crossclamp time (MHCA 120 minutes versus DHCA 142 minutes, p < 0.001), and cerebral perfusion time (MHCA 63 minutes versus DHCA 58 minutes, p < 0.001). Of note, there was no difference in neurologic outcomes nor in-hospital mortality for the two temperature groups. Multivariable analysis of risk factors for mortality included CPB time (odds ratio [OR] 1.006; p < 0.001), concomitant mitral valve surgery (OR 3.070; p = 0.003), emergent operation (OR 2.924; p < 0.001), and poor ejection fraction (OR 3.133; p = 0.011). Independent risk factors for stroke included coronary artery disease (OR 1.856; p < 0.001), cerebral vascular disease (OR 2.172; p < 0.001), emergent operation (OR 2.109; p < 0.001), and CPB time (OR 1.004; p < 0.001). CONCLUSIONS: In this series, TOTAL with MHCA and ACP can be safely performed with acceptable operative risk. MHCA and ACP represent an effective strategy for TOTAL and may obviate the need for DHCA.

PMID- 29167029 TI - Intervention studies to foster resilience - A systematic review and proposal for a resilience framework in future intervention studies. AB - Psychological resilience refers to the phenomenon that many people are able to adapt to the challenges of life and maintain mental health despite exposure to adversity. This has stimulated research on training programs to foster psychological resilience. We evaluated concepts, methods and designs of 43 randomized controlled trials published between 1979 and 2014 which assessed the efficacy of such training programs and propose standards for future intervention research based on recent developments in the field. We found that concepts, methods and designs in current resilience intervention studies are of limited use to properly assess efficacy of interventions to foster resilience. Major problems are the use of definitions of resilience as trait or a composite of resilience factors, the use of unsuited assessment instruments, and inappropriate study designs. To overcome these challenges, we propose 1) an outcome-oriented definition of resilience, 2) an outcome-oriented assessment of resilience as change in mental health in relation to stressor load, and 3) methodological standards for suitable study designs of future intervention studies. Our proposals may contribute to an improved quality of resilience intervention studies and may stimulate further progress in this growing research field. PMID- 29167030 TI - Comparison of bronchodilator administration with vibrating mesh nebulizer and standard jet nebulizer in the emergency department. AB - INTRODUCTION: Projects comparing bronchodilator response by aerosol devices in the ED are limited. Evidence suggests that the vibrating mesh nebulizer (VMN) provides 5-fold greater aerosol delivery to the lung as compared to a jet nebulizer (JN). The aim of this project was to evaluate a new nebulizer deployed in an Emergency Department. METHODS: A quality improvement evaluation using a prospectively identified data set from the electronic medical record comparing all ED patients receiving aerosolized bronchodilators with the JN during September 2015 to those receiving aerosolized bronchodilators with the VMN during October 2015. RESULTS: 1594 records were extracted, 879 patients received bronchodilators via JN and 715 patients via the VMN. Admission rates in the VMN group were 28.1% and in the JN group at 41.4%. The total albuterol dose administered was significantly lower in the VMN group compared to the JN (p<0.001). No patient in the VMN group required >5mg albuterol to control symptoms (85% of the VMN group received only 2.5mg) whereas dosing in the JN group was higher in some patients (with 47% receiving only 2.5mg). The use of VMN was also associated with a 13% (37min) reduction in median length of stay in the ED. CONCLUSIONS: The VMN was associated with fewer admissions to the hospital, shorter length of stay in the ED and a reduction in albuterol dose. The device type was a predictor of discharge, disposition and amount of drug used. Randomized controlled studies are needed to corroborate these findings. PMID- 29167031 TI - Vaccination coverage in patients affected by chronic diseases: A 2014 cross sectional study among subjects hospitalized at Bari Policlinico General Hospital. AB - Subjects affected by at least 1 chronic disease are the target of influenza vaccination strategies because they are at high risk of influenza complications or death. The aim of this cross-sectional study is to evaluate flu and pneumococcal vaccination coverage (VC) in a sample of patients hospitalized at Bari Policlinico General Hospital (South Italy). According to national public health guidelines, these patients should have been vaccinated at hospital discharge by general practitioners. There were 540 patients involved in the study, and the average age was of 46.9 +/- 13.4 years (range, 0-64 years). We assessed the vaccination status of 412 of 540 (76.3%) patients. The overall VC was 22.8% (94/412) for influenza and 7.2% (30/412) for pneumococcal vaccine. Doctor recommendation has a pivotal importance in vaccine acceptance, and recent experiences seem to show a high efficacy of the vaccination offer during hospitalization. This model could be helpful to improve influenza and pneumococcal vaccination offers to patient with underlying chronic conditions. PMID- 29167032 TI - Using the Evidence-Based Practice Service Nursing Bundle to Increase Patient Satisfaction. AB - ABSTRACTINTRODUCTION: Patient satisfaction and patient experience goals are often linked to financial consequences. Although the link does exist, the bottom line is not only about money; it's about providing a quality experience for ED patients and creating an environment that engages staff. Evidence-based practice (EBP) strategies that have positive impact on patient perceptions of their ED care and increased satisfaction ratings include AIDET, Hourly Rounding, and Bedside Shift Report, which incorporate updates of test results and explanations of events occurring during a patient's visit. In addition to these outcomes, Hourly Rounding and Bedside Shift Report have been linked to patient safety improvements. Combining these strategies, our team created and implemented the service nursing bundle as a quality improvement (QI) initiative, with the goal of having a positive effect on patient experiences in emergency departments, represented by at least a 5% increase in overall quality-of-care ranking and ratings. METHODS: This QI project involved comparing professional research consultant (PRC) patient- satisfaction phone survey ratings from patients before and after ED staff members completed a 1-hour service nursing bundle class. In addition to the patient-satisfaction ratings, 1,104 audits evaluating staff use of the service bundle implementation were collected over an 8-week period.reading document: RESULTS: The random observational audits showed the adoption of the service nursing bundle as staff compliance started at 65% in week 1 compared with 100% by week 8. Before intervention (July 2015): 50% of patients rated their overall quality of care as excellent, yielding a benchmark ranking of 42.5 percentile. Postservice bundle education implementation (September 2015): 60% of patients rated their overall quality of care as excellent, increasing our ranking to the 85.5 percentile. The postservice bundle group was 1.5 times more likely to respond "excellent" to all 5 survey questions, which was statistically significant (z =2.82, P = 0.004). The patients' perceptions of total time spent in the emergency department and ratings of "excellent" revealed a significant statistical difference (before: 35.0%, after: 49.5%, X2 (1) = 4.24, P < 0.05). DISCUSSION: With the implementation of the bundle, our emergency department experienced an 11.8% increase in the number of patients rating their overall quality of care as excellent. This upsurge resulted in a 40% increase in overall quality of care, propelling our emergency department's ranking to the 85th percentile. PMID- 29167033 TI - Nursing Perceptions of the Emergency Severity Index as a Triage Tool in the United Arab Emirates: A Qualitative Analysis. AB - INTRODUCTION: With emergency department crowding becoming an increasing problem across the globe, nursing triage to prioritize patients receiving care is ever more important. ESI is the most common triage system used in the United States and is increasingly used worldwide. This qualitative study that explores emergency nursing perceptions of the ESI identifies strengths, weaknesses, and barriers to implementation of the ESI internationally. METHODS: We conducted a cross-sectional qualitative analysis using semistructured interviews of 27 emergency triage nurses. Content analysis was performed by 2 independent coders, using NVivo software to identify and analyze important themes. RESULTS: Interview coding revealed 7 core themes related to use of the ESI (frequencies indicated in parentheses): ease of use (90), speed and efficiency (135), patient safety (12), accuracy and reliability (30), challenging patient characteristics (123), subjectivity and variability (173), and effect of triage system on team dynamics (100). Intercoder agreement was excellent (Cohen's unweighted kappa = 0.84). Subjectivity and variability in ESI score assignment consistently emerged in all interviews and included variability in number and use of resources, definition of "high risk," nursing experience, and subjectivity in pain assessment. DISCUSSION: Although emergency nurses perceive the ESI as easy to use, there are concerns about the subjectivity and variability inherent in the ESI that can lead to a functional lack of triage and a burden of undifferentiated ESI level 3 patients. These limitations in separating critically ill patients and in stratifying patients based on anticipated required resources points to the need for improvement in the ESI algorithm or a more objective triage system that can predict patient outcomes. PMID- 29167034 TI - Body awareness training in the treatment of wearing-off related anxiety in patients with Parkinson's disease: Results from a pilot randomized controlled trial. AB - BACKGROUND: In Parkinson's disease (PD) patients, fluctuations in symptoms commonly occur after many years of dopamine replacement therapy. The so-called wearing-off phenomenon exists of both motor and non-motor symptoms, such as rigidity and anxiety. Current treatment options are limited and an integrated approach is needed to address the complex interactions between motor and non motor symptoms. Since wearing-off is eventually inevitable, treatment needs to focus on coping, acceptance and self-efficacy. We developed the body awareness training, named BEWARE, combining physical therapy with acceptance and commitment therapy to help PD patients deal better with wearing-off related anxiety (WRA). METHODS: This was an investigator-blinded randomized controlled trial. Forty PD patients with WRA were randomly assigned to the BEWARE or to the treatment as usual (TAU) condition. Assessments were performed prior to and immediately after the treatment period, and at 3-months follow up. The primary outcome was self efficacy, secondary outcomes focused on mobility, daily functioning, anxiety, depression and quality of life. RESULTS: There was no significant improvement in self-efficacy in the BEWARE treatment condition when compared to TAU. However, standing balance and emotional wellbeing showed a significant improvement, and feelings of stigmatization showed a trend-significant decrease in the BEWARE condition. CONCLUSIONS: We consider the BEWARE training to be a promising therapeutic approach to address WRA. Improvement points from the participants included 1) less frequent but longer therapy sessions; 2) active involvement of caregivers; and 3) the development of a supportive workbook. The optimized treatment protocol needs further evaluation in a phase III RCT. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02054845. PMID- 29167035 TI - Promoting empathy among medical students: A two-site randomized controlled study. AB - OBJECTIVE: To assess the effects of Balint groups on empathy measured by the Consultation And Relational Empathy Measure (CARE) scale rated by standardized patients during objective structured clinical examination and self-rated Jefferson's School Empathy Scale - Medical Student (JSPE-MS(c)) among fourth-year medical students. METHODS: A two-site randomized controlled trial were planned, from October 2015 to December 2015 at Paris Diderot and Paris Descartes University, France. Eligible students were fourth-year students who gave their consent to participate. Participants were allocated in equal proportion to the intervention group or to the control group. Participants in the intervention group received a training of 7 sessions of 1.5-hour Balint groups, over 3months. The main outcomes were CARE and the JSPE-MS(c) scores at follow-up. RESULTS: Data from 299 out of 352 randomized participants were analyzed: 155 in the intervention group and 144 in the control group, with no differences in baseline measures. There was no significant difference in CARE score at follow-up between the two groups (P=0.49). The intervention group displayed significantly higher JSPE-MS(c) score at follow-up than the control group [Mean (SD): 111.9 (10.6) versus 107.7 (12.7), P=0.002]. The JSPE-MS(c) score increased from baseline to follow-up in the intervention group, whereas it decreased in the control group [1.5 (9.1) versus -1.8 (10.8), P=0.006]. CONCLUSIONS: Balint groups may contribute to promote clinical empathy among medical students. TRIAL REGISTRATION: NCT02681380. PMID- 29167036 TI - Inverse association between hyperthymic affective temperament and coronary atherosclerosis: A coronary computed tomography angiography study. AB - OBJECTIVE: A bidirectional relationship exists between psychiatric disorders and cardiovascular diseases, however less is known with regards to personality traits. Accumulating data suggest that affective temperaments are both associated with psychiatric and somatic diseases. The aim of our study was to evaluate the associations between different affective temperaments and the presence of coronary atherosclerosis. METHODS: 200 consecutive patients referred to coronary computed tomography angiography (CCTA) due to suspected coronary artery disease (CAD) were included in our study. Medical history and demographic parameters were recorded and all patients completed the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) and the Beck Depression Inventory (BDI). The presence of coronary artery disease was evaluated based on the CCTA images. RESULTS: 39 patients were free of any coronary atherosclerosis (CCTA-) and 161 had coronary atherosclerosis (CCTA+). Hyperthymic affective temperament score was higher in CCTA- subjects as compared to CCTA+ (13.1+/-3.0 vs 11.5+/-4.6, p=0.010, respectively). Hyperthymic affective temperament score showed a significant independent, inverse relationship with coronary atherosclerosis (OR: 0.91 CI: 0.82-0.99, p=0.04). CONCLUSION: Our results suggest that hyperthymic affective temperament is independently associated with the absence of CAD. It requires further research to delineate the mechanism mediating the effect of hyperthymia on better coronary artery health and establishing potential biochemical or behavioral factors, both of which could be exploited for prevention and treatment purposes. But it is plausible, that the evaluation of affective temperaments have importance both in relation with psychiatric and cardiovascular disorders. PMID- 29167037 TI - The burden of suicidal ideation among persons with type II diabetes: A scoping review. AB - OBJECTIVE: Diabetes is a major global health concern. People with diabetes have worse mental health outcomes than those without diabetes. Researchers have recently sought to examine the relationship between diabetes and suicidal ideation. The aim of this study is to determine the burden of suicidal ideation among adults with type II diabetes from existing literature. METHODS: We conducted a scoping review of published literature in PubMed, PsycINFO, CINAHL, Web of Science, and Google Scholar published before March 2017. To identify relevant literature, search terms included suicidal ideation and type II diabetes. The search was limited to English language peer-reviewed journal articles. The main outcome of interest was suicidal ideation captured on a validated scale in a population with type II diabetes. RESULTS: This review resulted in 10 relevant studies, which reported the prevalence of suicidal ideation ranging from 2.5-51.4% with a median prevalence of 18.6% among adults with diabetes. Across the five studies reporting the associated risks, all but one study found a significant risk for persons with diabetes to endorse suicidal ideation and only three studies adjusted for depression. CONCLUSIONS: This review demonstrates the need for future studies to investigate potential mechanistic pathways of suicidality among persons with diabetes. PMID- 29167038 TI - Oral contraceptives positively affect mood in healthy PMS-free women: A longitudinal study. AB - OBJECTIVE: Menstrual cycle phase and oral contraceptives (OC) use influence mood and cognition and these effects may be moderated by the mineralocorticoid receptor (MR) genotype. The effect of menstrual cycle phase on mood may be increased if participants know that this is the focus of study. We assessed aspects associated with reproductive depression such as mood, interpersonal sensitivity, affect lability and depressive cognitions in MR-genotyped OC-users and naturally cycling (NC) women in a carefully masked design. METHODS: A homogenous sample of healthy, PMS-free, pre-menopausal MR-genotyped women (n=92) completed online questionnaires eight times during two consecutive cycles. RESULTS: The masking of the research question was successful. OC-users did not differ significantly from NC women in positive and negative affect at the time of assessment, personality characteristics (e.g. neuroticism) or mental and physical health. Both groups reported more shifts in anger in the first cycle week (p<0.001; etap2=0.08). Compared to NC women, OC-users reported fewer mood-shifts between depression and elation in the mid-luteal phase of the menstrual cycle (p=0.002; etap2=0.10) and had fewer ruminating thoughts at all phases (p=0.003; etap2=0.11). Effects of MR-genotype were not significant after correction for multiple comparisons. CONCLUSION: OC users scored more favorably on measures associated with reproductive depression. OC users also showed a decreased affect variability possibly indicating an emotional blunting effect, which is in line with previous reports on affect-stabilizing effects of OC. Limitations were loss of cases due to irregularities in the menstrual cycle length and possible confounding by the 'survivor effect', since almost all OC-users took OC for more than a year. PMID- 29167039 TI - Psychological and psychiatric symptoms of terminally ill patients with cancer and their family caregivers in the home-care setting: A nation-wide survey from the perspective of bereaved family members in Japan. AB - OBJECTIVE: The psychological and psychiatric symptoms of terminally ill cancer patients are highly problematic and have been associated with greater burden among caregivers. Until now, the extent of these problems in the home care setting was unclear. METHODS: This retrospective study was conducted as part of a nationwide survey from the perspective of bereaved family members in Japan (J HOPE3). The bereaved family members rated the symptoms of delirium and suicidal ideation of patients with cancer, and the sleeplessness and depressed mood of family caregivers utilizing home care services in the one month before the patients' deaths. Regression analyses were performed to identify factors associated with caregivers' sleeplessness or depressed mood. RESULTS: Of the 532 subjects analyzed, between 17% and 65% of patients experienced various symptoms of delirium, and 27% suicidal ideation. Among family caregivers, 60% experienced sleeplessness and 35% experienced depressed mood at least once during the week. Caregivers' psychological symptoms were associated with their own poor health status, being the spouse of the patient, and the patients' psychological or psychiatric symptoms. To manage patients' symptoms, 11% of caregivers had consulted psychiatrists or psychologists while another 11% wanted to do so. CONCLUSION: Psychological problems assessed were common among patients with cancer and their family caregivers in the one month of home care prior to the patient's death. An effective complementary care system, run by home-visit physicians, nurses, and experts in mental disorders, is needed. PMID- 29167040 TI - Delirium in the intensive care setting and the Richmond Agitation and Sedation Scale (RASS): Drowsiness increases the risk and is subthreshold for delirium. AB - INTRODUCTION: Sedation is a core concept in the intensive care setting, however, the impact of sedation on delirium has not yet been studied to date. METHODS: In this prospective cohort study, 225 patients with Richmond Agitation and Sedation (RASS) scores of -1 - drowsiness and 0 - alert- and calmness were assessed with the Delirium Rating Scale-Revised 1998 (DRS-R-98) and DSM-IV-TR-determined diagnosis of delirium assessing drowsiness versus alertness. RESULTS: By itself, drowsiness increased the odds for developing delirium eightfold (OR 7.88 p<0.001) and rates of delirium were 68.2 and 21.4%, respectively. Further, in the drowsy patient, delirium was more severe. In the presence of drowsiness, delirium was characterized by sleep-wake cycle disturbances and language abnormalities. These two features, in addition to psychomotor retardation, allowed the correct classification of delirium at RASS-1. The same features, in addition to thought abnormalities and the impairment in the cognitive domain, orientation, attention, short- and long-term memory representing the core domains of delirium, or the temporal onset were very sensitive towards delirium, however lacked specificity. Conversely, delusions, perceptual abnormalities and lability of affect representing the non-core domain were very specific for delirium in the drowsy, however, not very sensitive. In the absence of delirium, drowsiness caused attentional impairment and language abnormalities. CONCLUSION: Drowsiness increased the odds for developing delirium eightfold and caused more severe delirium, which was characterized by sleep-wake cycle and language abnormalities. Further, drowsiness by itself caused attentional impairment and language abnormalities, thus, with its disturbance in consciousness was subthreshold for delirium. PMID- 29167041 TI - Efficacy of an internet-based cognitive behavioral stress management training in women with idiopathic preterm labor: A randomized controlled intervention study. AB - OBJECTIVE: This randomized controlled trial aimed at evaluating the efficacy of an internet-based cognitive behavioral stress management program (IB-CBSM) for pregnant women with preterm labor (PTL) on birth outcome and stress-related psychological and biological parameters. METHODS: 93 pregnant women with PTL (gestational age 18-32) were assigned to either the IB-CBSM (n=50) or a control group (CG) based on distraction (n=43). Participants in both groups worked through six weekly modules. Birth outcome measures included gestational age, neonatal weight and length at birth and the rate of preterm birth (PTB). Questionnaires assessed psychological wellbeing and the activity of the HPA-axis was measured with the cortisol awakening reaction (CAR), both before (T1) and after the intervention (T2). RESULTS: Birth outcome and psychological wellbeing did not differ between IB-CBSM and CG. However, psychological wellbeing was higher after both interventions (PSS: etap2=0.455, STAIX1: etap2=0.455, STAIX2: etap2=0.936, PRAT: etap2=0.465, EPDS: etap2=0.856). Cortisol levels were stable and did not alter differently between groups from T1 to T2. Higher cortisol levels were associated with lower gestational age at birth, whereas no significant correlations were found between weight and length at birth. CONCLUSIONS: Although there were no significant differences between the two groups and birth outcome, psychological and biological parameters, both interventions (CBSM and CG) showed equivalent effects and proved to be beneficial with regard to psychosocial distress and well-being. Further research is needed to investigate CBSM and distraction interventions for pregnant women at risk for PTB together with a non-intervention control condition. PMID- 29167042 TI - Classifying post-stroke fatigue: Optimal cut-off on the Fatigue Assessment Scale. AB - OBJECTIVE: Post-stroke fatigue is common and has debilitating effects on independence and quality of life. The Fatigue Assessment Scale (FAS) is a valid screening tool for fatigue after stroke, but there is no established cut-off. We sought to identify the optimal cut-off for classifying post-stroke fatigue on the FAS. METHODS: In retrospective analysis of two independent datasets (the '2015' and '2007' studies), we evaluated the predictive validity of FAS score against a case definition of fatigue (the criterion standard). Area under the curve (AUC) and sensitivity and specificity at the optimal cut-off were established in the larger 2015 dataset (n=126), and then independently validated in the 2007 dataset (n=52). RESULTS: In the 2015 dataset, AUC was 0.78 (95% CI 0.70-0.86), with the optimal >=24 cut-off giving a sensitivity of 0.82 and specificity of 0.66. The 2007 dataset had an AUC of 0.83 (95% CI 0.71-0.94), and applying the >=24 cut-off gave a sensitivity of 0.84 and specificity of 0.67. Post-hoc analysis of the 2015 dataset revealed that using only the 3 most predictive FAS items together ('FAS 3') also yielded good validity: AUC 0.81 (95% CI 0.73-0.89), with sensitivity of 0.83 and specificity of 0.75 at the optimal >=8 cut-off. CONCLUSION: We propose >=24 as a cut-off for classifying post-stroke fatigue on the FAS. While further validation work is needed, this is a positive step towards a coherent approach to reporting fatigue prevalence using the FAS. PMID- 29167043 TI - Exposure to teasing on popular television shows and associations with adolescent body satisfaction. AB - OBJECTIVE: This study uses a novel mixed methods design to examine the relationship between incidents of teasing in popular television shows and body satisfaction of adolescent viewers. METHODS: Survey data were used to identify 25 favorite television shows in a large population-based sample of Minnesota adolescents (N=2793, age=14.4years). Data from content analysis of teasing incidents in popular shows were linked to adolescent survey data. Linear regression models examined associations between exposure to on-screen teasing in adolescents' own favorite shows and their body satisfaction. Effect modification by adolescent weight status was tested using interaction terms. RESULTS: Teasing on TV was common, with 3.3 incidents per episode; over one-quarter of teasing was weight/shape-related. Exposure to weight/shape-related teasing (beta=-0.43, p=0.008) and teasing with overweight targets (beta=-0.03, p=0.02) was inversely associated with girls' body satisfaction; no associations were found for boys. Findings were similar regardless of the adolescent viewer's weight status. CONCLUSIONS: Families, health care providers, media literacy programs and the entertainment industry are encouraged to consider the negative effects exposure to weight stigmatization can have on adolescent girls. PMID- 29167044 TI - Psychological stress declines rapidly from age 50 in the United States: Yet another well-being paradox. AB - OBJECTIVES: Although there is evidence that evaluative subjective well-being (e.g., life satisfaction) shows a U-shaped pattern with highest satisfaction in the youngest and oldest years and lowest in the middle years of adulthood, much less is known about experiential well-being. We explore a negative indicator of experiential well-being (perceived stress), examine its association with age, and explore possible determinants of the age pattern. METHODS: Using Gallup Healthways survey data of over 1.5 million U.S. respondents, we analyzed a question asking about stress yesterday and demographic determinants of the pattern. To confirm this pattern, data on stress was analyzed from the American Time Use Survey and data on distress was analyzed from the Health and Retirement Survey. RESULTS: We show that ratings of daily, perceived stressfulness yield a paradox, with high levels from the 20's through about age 50, followed by a precipitous decline through the 70's. Data from the other two surveys confirmed the age pattern for stress. Regressions with the Gallup-Healthways data statistically controlled several third-variables, yet none substantially altered the pattern. CONCLUSION: We argue that this new experiential well-being pattern informs us about aging in the US and the "paradox" calls out for explanation. PMID- 29167045 TI - Long-term caregiving is associated with impaired cardiovagal baroreflex. AB - OBJECTIVE: Caregiving stress is associated with increased risk of cardiovascular disease (CVD). Inability to adequately regulate blood pressure is a possible underlying mechanism explaining this risk. We examined the relationship between length of caregiving and cardiovagal baroreflex sensitivity (cBRS) to better understand the link between caregiving and CVD risk. METHODS: A total of 146 elderly individuals (>=55years) participated in this study, of whom 96 were providing in-home care to a spouse with dementia and 50 were healthy controls married to a non-demented spouse (i.e., non-caregivers). Among the caregivers, 56 were short-term caregivers (caring<4years) and 40 were long-term caregivers (caring>=4years). A multiple linear regression model, with contrast codes comparing short and long-term caregivers with non-caregivers was used to understand relationships between chronic caregiving and cBRS. RESULTS: After controlling for relevant demographic and health characteristics, mean+/-SE log transformed cBRS for non-caregivers was 0.971+/-0.029. Relative to non caregivers, the long-term caregivers had significantly impaired cBRS (0.860+/ 0.033; p=0.013). However, mean cBRS for short-term caregivers did not significant differ from non-caregivers (0.911+/-0.028; p=0.144). CONCLUSION: These results suggest that long-term caregiving stress is associated with an impaired cBRS. Accumulation of stress from years of caregiving could result in worse cBRS function, which could be a mechanistic explanation for the correlation between caregiving stress and the increased risk of CVD. PMID- 29167046 TI - Changes in Allostatic Load during workplace reorganization. AB - OBJECTIVE: Allostatic Load (AL) represents the strain on the body produced by repeated physiologic or allostatic responses activated during stressful situations. Several cross-sectional studies have found empirical substantiation for the relationship between impaired psychosocial work environment and high AL. The aim of this longitudinal study is to investigate changes in AL during workplace reorganization that has been shown to cause impaired psychosocial work environment. Moreover, we aim to investigate the association between changes in AL and changes in psychosocial work environment (job strain, effort-reward imbalance) and psychological distress (stress symptoms and perceived stress). METHODS: A major reorganization of non-state public offices was effectuated in Denmark on 1 January 2007. In 2006 and 2008, we collected clinical and questionnaire data from 359 participants, 265 women and 94 men, employed in seven municipality or county administrations. Four municipalities and one county merged with others, while one municipality and one county remained unmerged. We calculated the AL score based on 13 physiological markers reflecting stress responses of the cardiovascular, metabolic, neuroendocrine and immune systems. We analysed changes in AL from 2006 to 2008. RESULTS: AL increased significantly during workplace reorganization in the whole study group but we observed only a tendency of significant increase in AL in the merger group compared with the control group. Moreover, we observed no association between the changes in AL and changes in psychosocial work environment and psychological distress. CONCLUSIONS: This result leaves the conclusion unclear but contributes to the limited research in this area with a longitudinal design and focus on low-risk levels and small changes in AL in healthy people as predictor of future disease. PMID- 29167047 TI - Systematic review of measurement properties of questionnaires measuring somatization in primary care patients. AB - OBJECTIVE: The aim of this review is to critically appraise the evidence on measurement properties of self-report questionnaires measuring somatization in adult primary care patients and to provide recommendations about which questionnaires are most useful for this purpose. METHODS: We assessed the methodological quality of included studies using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. To draw overall conclusions about the quality of the questionnaires, we conducted an evidence synthesis using predefined criteria for judging the measurement properties. RESULTS: We found 24 articles on 9 questionnaires. Studies on the Patient Health Questionnaire-15 (PHQ-15) and the Four-Dimensional Symptom Questionnaire (4DSQ) somatization subscale prevailed and covered the broadest range of measurement properties. These questionnaires had the best internal consistency, test-retest reliability, structural validity, and construct validity. The PHQ-15 also had good criterion validity, whereas the 4DSQ somatization subscale was validated in several languages. The Bodily Distress Syndrome (BDS) checklist had good internal consistency and structural validity. Some evidence was found for good construct validity and criterion validity of the Physical Symptom Checklist (PSC-51) and good construct validity of the Symptom Check-List (SCL-90-R) somatization subscale. However, these three questionnaires were only studied in a small number of primary care studies. CONCLUSION: Based on our findings, we recommend the use of either the PHQ-15 or 4DSQ somatization subscale for somatization in primary care. Other questionnaires, such as the BDS checklist, PSC-51 and the SCL-90-R somatization subscale show promising results but have not been studied extensively in primary care. PMID- 29167048 TI - Prevalence and risk factors of excessive daytime sleepiness in insomnia sufferers: A study with 1311 individuals. AB - BACKGROUND: Several studies have investigated the prevalence and risk factors of excessive daytime sleepiness in the general population. However, few studies have investigated these in the particular subpopulation of insomnia sufferers. Thus, the aim of this study was to examine the prevalence and risk factors of excessive daytime sleepiness in a large sample of insomnia sufferers. METHODS: Data from 1311 insomnia sufferers with age>=18years and recruited from the research database of the sleep laboratory of the Erasme Hospital were analysed. A score>10 on the Epworth scale was used as the cut-off score for excessive daytime sleepiness. Logistic regression analyses were conducted to examine clinical and demographic risk factors of excessive daytime sleepiness in insomnia sufferers. RESULTS: The prevalence of excessive daytime sleepiness in our sample was 45.61%. Multivariate logistic regression analysis revealed that non-use of Z-drugs, non use of Trazodone alone or in combination, body mass index>=25 & <30kg/m2, body mass index>=30kg/m2, age>=18 & <40years, age>=40 & <65years, Beck depression inventory score>=5 & <16, Beck depression inventory score>=16, apnea-hypopnea index>=15/h, and use of selective serotonin reuptake inhibitors were significant risk factors of excessive daytime sleepiness in the subpopulation of insomnia sufferers. CONCLUSION: Excessive daytime sleepiness is a common complaint for individuals with insomnia. In this subpopulation, most of the risk factors for excessive daytime sleepiness are reversible, which justifies better management of this complaint to avoid its negative consequences. PMID- 29167049 TI - Does the presence of multiple sclerosis impact on symptom profile in depressed patients? AB - OBJECTIVE: Major depressive disorder (MDD) is common in patients with multiple sclerosis (MS) but may remain unrecognized because of overlapping symptoms and different presentation due to its specific MS-related neurobiological aetiology. We aimed to investigate the clinical profile of MDD in MS. METHODS: In a sample of MDD patients with MS (n=83) and without MS (n=782), MDD characteristics, 30 depressive symptoms, and sum scores of cognitive, somatic, atypical and melancholic symptom clusters were compared using logistic regression analyses and analysis of co-variance. RESULTS: MDD in MS was characterized by older age of onset (p<0.001), and fewer comorbid anxiety disorders (37% versus 72%; p<0.001). The symptom 'future pessimism' was more common in MS patients (OR=1.62; 95%CI=1.02-2.59). 'Diminished capacity for pleasure/enjoyment' (OR=0.44; 95%CI=0.24-0.78), 'increased appetite' (OR=0.40; 95%CI=0.19-0.85), 'arousal symptoms' (OR=0.49; 95%CI=0.28-0.84), and 'panic/phobic symptoms' (OR=0.49; 95%CI=0.29-0.84) were less common in MS patients. Twenty-five symptoms (83%) out of 30, including depression's core symptoms (sadness and loss of interest) were not differentially associated with MS and no differences existed for the symptom clusters. CONCLUSION: Only subtle differences in depressive symptom profiles existed between MDD patients with and without MS. The clinical profile of depression remains valid among MS patients, although it presents with diminished anxiety distress and comorbidity. PMID- 29167050 TI - Insecure attachment style and cumulative traumatic life events in patients with somatoform pain disorder: A cross-sectional study. AB - OBJECTIVE: Current models assume somatoform pain disorder (SPD) to be the result of a complex interaction between bio- and psychosocial factors, but the etiology is still not well understood. This study aimed to investigate the distribution of attachment style and the frequency of traumatic life events, especially childhood adversities, in patients with SPD compared to healthy controls. METHODS: We compared 65 patients with SPD (confirmed by Structured Clinical Interview, SCID I) to 65 age- and gender-matched healthy controls. The following questionnaires were employed: Relationship Scale Questionnaire (RSQ), Essen Trauma Inventory (ETI), Childhood Trauma Questionnaire (CTQ) and Patient Health Questionnaire (PHQ 15). A logistic regression analysis was used to identify the association between SPD and psychological factors. RESULTS: Insecure attachment was significantly more prevalent (60%) in patients with SPD compared to healthy subjects (14%; p<0.001). Overall, 70.4% of patients with SPD reported three or more traumatic events in their life, compared with healthy subjects who reported predominantly one (40%). Patients with SPD scored significantly higher in all CTQ subscales compared to the healthy controls. The factor most strongly related with SPD was the insecure attachment style (OR=11.20, 95% CI: 1.32-94.86). Other significant predictive factors were depression (OR=3.35, 95% CI: 1.84-6.11) and number of traumatic events (OR=2.04, 95% CI: 1.06-3.92). Insecure attachment, depression symptoms and the number of traumatic events explained 86.2% of the variance. CONCLUSIONS: The high predictive value of insecure attachment style and cumulative traumatic events emphasize their importance as risk factors of SPD. PMID- 29167051 TI - Discrimination and anger control as pathways linking socioeconomic disadvantage to allostatic load in midlife. AB - OBJECTIVE: Recent evidence suggests that experiences of discrimination contribute to socioeconomic status health disparities. The current study examined if the experience and regulation of anger-an expected emotional response to discrimination-serves as an explanatory factor for the previously documented links between socioeconomic disadvantage (SED), discrimination, and allostatic load. METHODS: Data were drawn from the second wave of the Midlife in the United States (MIDUS) study and included 909 adults who participated in the biomarkers subproject. RESULTS: Results revealed that perceived discrimination was associated with higher levels of allostatic load. Furthermore, we found evidence that perceived discrimination and anger control sequentially explained the relationship between SED and allostatic load, such that greater discrimination was associated with lower levels of anger control, which, in turn accounted for the effects of discrimination on allostatic load. These results remained significant after controlling for negative affect, positive affect, other forms of anger expression, as well as demographic covariates. CONCLUSIONS: Our findings suggest that low anger control may be an important psychological pathway through which experiences of discrimination influence health. PMID- 29167052 TI - The impact of exposure-based cognitive behavior therapy for severe health anxiety on self-rated health: Results from a randomized trial. AB - OBJECTIVE: Self-rated health (SRH) has been shown to be a stable predictor of illness and mortality. Improvement in SRH, even in the absence of change in objective health, predicts better health and reduced mortality. Severe health anxiety (SHA) is characterized by fear of illness and distorted health perception. The objective of the present study was to investigate if exposure based cognitive behavior therapy (CBT) for SHA can lead to improvement in SRH and whether this improvement is mediated by reduced health anxiety. METHODS: Data were collected from a randomized controlled trial where participants with SHA were allocated to 12weeks of exposure-based CBT (n=99) for SHA or to a no treatment control condition (n=33). The mediation analysis was based on SRH- and health anxiety data collected weekly during the treatment phase. RESULTS: Linear mixed effects models analysis showed a significant interaction effect of group and time indicating superior improvements in SRH in exposure-based CBT compared to the control condition (Z=2.69, p=0.007). The controlled effect size was moderately large (d=0.64) and improvements were stable at 1-year follow-up. Reduced health anxiety was a significant mediator of improvement in SRH. CONCLUSIONS: 12weeks of exposure-based CBT for SHA can lead to significant improvements in SRH. Considering the previously established importance of SRH as a predictor for disease and mortality, exposure-based CBT for severe health anxiety may lead to improvements on several important health parameters, possibly even increasing the likelihood of longevity. PMID- 29167053 TI - Autonomic nervous system function, activity patterns, and sleep after physical or cognitive challenge in people with chronic fatigue syndrome. AB - OBJECTIVE: To explore changes in autonomic functioning, sleep, and physical activity during a post-exertional symptom exacerbation induced by physical or cognitive challenge in participants with chronic fatigue syndrome (CFS). METHODS: Thirty-five participants with CFS reported fatigue levels 24-h before, immediately before, immediately after, and 24-h after the completion of previously characterised physical (stationary cycling) or cognitive (simulated driving) challenges. Participants also provided ratings of their sleep quality and sleep duration for the night before, and after, the challenge. Continuous ambulatory electrocardiography (ECG) and physical activity was recorded from 24-h prior, until 24-h after, the challenge. Heart rate (HR) and HR variability (HRV, as high frequency power in normalized units) was derived from the ECG trace for periods of wake and sleep. RESULTS: Both physical and cognitive challenges induced an immediate exacerbation of the fatigue state (p<0.001), which remained elevated 24-h post-challenge. After completing the challenges, participants spent a greater proportion of wakeful hours lying down (p=0.024), but did not experience significant changes in sleep quality or sleep duration. Although the normal changes in HR and HRV during the transition from wakefulness to sleep were evident, the magnitude of the increase in HRV was significantly lower after completing the challenge (p=0.016). CONCLUSION: Preliminary evidence of reduced nocturnal parasympathetic activity, and increased periods of inactivity, were found during post-exertional fatigue in a well-defined group of participants with CFS. Larger studies employing challenge paradigms are warranted to further explore the underlying pathophysiological mechanisms of post-exertional fatigue in CFS. PMID- 29167054 TI - Cerebral gray matter changes in persistent postural perceptual dizziness. AB - BACKGROUND: Persistent postural perceptual dizziness (PPPD) is the most common vestibular syndrome in middle-aged patients. Multisensory maladjustment involving alterations of sensory response pattern including vestibular, visual and motion stimuli is thought to be a key pathophysiological correlate of this disorder. OBJECTIVE: We aimed to identify regional gray matter changes in PPPD patients that might be involved in the underlying pathophysiology of this disorder. METHODS: 42 PPPD patients and healthy age and gender matched controls were investigated using magnetic resonance imaging-based voxel-based morphometry. All patients fulfilled the current diagnostic criteria for PPPD, established by the Barany-Society based on previous criteria for chronic subjective dizziness and phobic postural vertigo. RESULTS: PPPD patients showed gray matter volume decrease in the temporal cortex, cingulate cortex, precentral gyrus, hippocampus, dorsolateral prefrontal cortex, caudate nucleus and the cerebellum. A negative correlation of disease duration and gray matter volume was observed in the visual cortex, supplementary motor area and somatosensory processing structures. CONCLUSIONS: In patients with PPPD areas involved in multisensory vestibular processing show gray matter volume decrease. These brain regions resemble those previously described for other vestibular disorders. Longer duration of disease leads to a more pronounced gray matter alteration, which might represent maladaptive mechanisms within the course of disease.

PMID- 29167056 TI - Diffusion Tensor Imaging as a Biomarker to Differentiate Acute Disseminated Encephalomyelitis From Multiple Sclerosis at First Demyelination. AB - BACKGROUND: There are no clinical features or biomarkers that can reliably differentiate acute disseminated encephalomyelitis from multiple sclerosis at the first demyelination attack. Consequently, a final diagnosis is sometimes delayed by months and years of follow-up. Early treatment for multiple sclerosis is recommended to reduce long-term disability. Therefore, we intend to explore neuroimaging biomarkers that can reliably distinguish between the two diagnoses. METHODS: We reviewed prospectively collected clinical, standard MRI and diffusion tensor imaging data from 12 pediatric patients who presented with acute demyelination with and without encephalopathy. Patients were followed for an average of 6.5 years to determine the accuracy of final diagnosis. Final diagnosis was determined using 2013 International Pediatric MS Study Group criteria. Control subjects consisted of four age-matched healthy individuals for each patient. RESULTS: The study population consisted of six patients with central nervous system demyelination with encephalopathy with a presumed diagnosis of acute disseminated encephalomyelitis and six without encephalopathy with a presumed diagnosis of multiple sclerosis or clinically isolated syndrome at high risk for multiple sclerosis. During follow-up, two patients with initial diagnosis of acute disseminated encephalomyelitis were later diagnosed with multiple sclerosis. Diffusion tensor imaging region of interest analysis of baseline scans showed differences between final diagnosis of multiple sclerosis and acute disseminated encephalomyelitis patients, whereby low fractional anisotropy and high radial diffusivity occurred in multiple sclerosis patients compared with acute disseminated encephalomyelitis patients and the age-matched controls. CONCLUSIONS: Fractional anisotropy and radial diffusivity measures may have the potential to serve as biomarkers for distinguishing acute disseminated encephalomyelitis from multiple sclerosis at the onset.

PMID- 29167058 TI - Neuroimaging Findings in Normocephalic Newborns With Intrauterine Zika Virus Exposure. AB - BACKGROUND: Congenital Zika infection can result in a spectrum of neurological abnormalities in the newborn. Newborns exposed to Zika virus in utero often have neuroimaging as part of their clinical evaluation. METHODS: Through the Congenital Zika Program at Children's National Health System in Washington DC, we performed fetal or neonatal neuroimaging, including magnetic resonance imaging and ultrasound, on over 70 fetuses or neonates with intrauterine Zika exposure. Novel findings on neonatal brain magnetic resonance imaging were observed in two instances. RESULTS: Gadolinium-contrast magnetic resonance imaging showed enhancement of multiple cranial nerves at three days of age on one infant. Another infant underwent magnetic resonance imaging at 16 days of age and was shown to have a chronic ischemic cerebral infarction. This infant had previously normal fetal magnetic resonance imaging. CONCLUSION: Cranial nerve enhancement and cerebral infarction may be among the expanding list of neurological findings in congenital Zika infection. Postnatal brain magnetic resonance imaging should be considered for newborns exposed to Zika virus in utero. PMID- 29167060 TI - Aging process, adherence to Mediterranean diet and nutritional status in a large cohort of nonagenarians: Effects on endothelial progenitor cells. AB - BACKGROUND AND AIM: Adherence to the Mediterranean Diet (MD) has been associated with a longer and better life. The aim of this study was to examine the effects of adherence to the MD, and of nutritional habits on endothelial progenitor (EPCs) and circulating progenitor (CPCs) cells in a cohort of nonagenarians enrolled within the Mugello Study, an epidemiological study aimed at investigating both clinically relevant geriatric items and various health issues, including those related to nutritional status. METHODS AND RESULTS: Four hundred twenty-one nonagenarians (306 F, 115 M, mean age: 93.1 +/- 3.2 years) were evaluated. Adherence to MD was assessed through the Mediterranean Diet Score. Elderly subjects who were in the fourth quartile of the Mediterranean diet score showed significantly higher EPCs than subjects grouped into the other three quartiles. After adjustment for confounders, elderly subjects who were in the highest quartile of adherence to the MD score reported to have EPCs' levels significantly higher than those who reported lower values of adherence to the MD. Furthermore, by analyzing different food categories, it was reported that daily consumption of olive oil and a higher consumption of fruit and vegetables showed higher CPCs CD34+ and EPCs CD34+/KDR+ than subjects with not daily or lower consumption. CONCLUSION: Our results support the hypothesis that the adherence to MD, as well as a daily consumption of olive oil and fruit and vegetables, characteristics of MD, may protect against the development of endothelial dysfunction through increasing EPCs and CPCs in older age. PMID- 29167059 TI - Dietary total, animal, vegetable calcium and type 2 diabetes incidence among Korean adults: The Korean Multi-Rural Communities Cohort (MRCohort). AB - BACKGROUND AND AIMS: Although a possible mechanism for developing type 2 diabetes in relation to calcium intake has been suggested, there is currently little epidemiological evidence on the association between dietary calcium and type 2 diabetes (T2D). This study aimed to evaluate the prospective association between dietary calcium and T2D incidence among adults 40 years of age or over, from the Multi-rural Communities Cohort (MRCohort), South Korea. METHODS AND RESULTS: In total, 8313 participants (3033 men and 5280 women) who did not have diabetes at baseline were recruited between 2005 and 2013. The incidence rate ratio (IRR) was estimated using a modified Poisson regression model with a robust error estimator. During follow-up (31,570 person-years), 322 T2D cases were newly diagnosed. Dietary calcium (total and vegetable calcium) were inversely associated with the risk of T2D incidence among women (IRR = 0.61, 95% CI = 0.43 0.86, P for trend = 0.007 in third tertile of baseline total calcium intake comparing to the first tertile; IRR = 0.57, 95% CI = 0.39-0.84, P for trend = 0.006 for baseline vegetable calcium intake), not for men. The tendency of those inverse associations remained in both the normal fasting blood glucose group and the impaired fasting blood glucose group and were independent of obesity, smoking, and magnesium intake. CONCLUSIONS: Total and vegetable calcium may be inversely associated with T2D incidence among women, regardless of impaired fasting blood glucose group or normal group. The associations may be potentially dose-responsive. Moderate dietary calcium may be related to lower risk of T2D incidence comparing to low intake group among women. PMID- 29167061 TI - Implementation and outcomes of hospital-wide computerized antimicrobial approval system and on-the-spot education in a traumatic intensive care unit in Taiwan. AB - BACKGROUND/PURPOSE: Inappropriate prescribing of antibiotics is a major health care problem in intensive care units (ICUs). This study evaluates the impact of a direct hospital-wide computerized antimicrobial approval system (HCAAS) and on the-spot education for practitioners in a neurosurgical ICU in Taiwan. METHODS: We retrospectively analyzed the medical records monthly of patients who were admitted to the neurosurgical ICU during a period of 7 years and 7 months. A pretest-post-test time series analysis, comparing the three periods: period I (no infectious disease (ID) physician), period II (part-time ID physicians), and period III (full-time ID physician). Antimicrobial consumption and expenditure, incidence of hospital-associated infections, prevalence of healthcare-associated bacterial isolates, in-hospital mortality rates, and indication of antibiotics usage were analyzed. RESULTS: Full-time ID physician can increase the consumption of narrow-spectrum antimicrobials (cefazolin, and cefuroxime), and decrease the consumptions of broad-spectrum antimicrobials (ceftazidime, cefepime, and vancomycin) compared to part-time ID physicians. From period I to period III, the expenditure of antimicrobials, incidence of hospital-associated pneumonia, and the in-hospital mortality rates (crude, sepsis-related, and overall infection related mortality) decreased statistically. The prevalence of extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae, and Carbapenems-resistant Pseudomonas aeruginosa remained at low level after HCAAS implementation. From 2007 to 2009, the rational antibiotics usage continued to increase, resulting from to more prophylaxis and appropriate microbiologic proof, but less empiric antimicrobial therapy. CONCLUSION: Implementation of HCAAS and long-term on-the-spot education by full-time ID physician can reduce antimicrobial consumption, cost, and improve inappropriate antibiotic usage whilst not compromising healthcare quality. PMID- 29167062 TI - Mechanistic insights into the detection of free fatty and bile acids by ileal glucagon-like peptide-1 secreting cells. AB - OBJECTIVES: The aim of this study was to investigate the electrical properties of ileal Glucagon-like peptide 1 (GLP-1) secreting L-cells using murine organoid cultures and the electrophysiological and intracellular signaling pathways recruited following activation of the Galphaq-coupled free fatty acid receptors FFA1 and Galphas-coupled bile acid receptors GPBAR1. METHODS: Experiments were performed using ileal organoids generated from mice transgenically expressing fluorescent reporters (Epac2-camps and GCaMP3) under control of the proglucagon promoter. Electrophysiology and single cell imaging were performed on identified L-cells in organoids, and GLP-1 secretion from cultured organoids was measured by immunoassay. RESULTS: The FFA1 ligand TAK-875 triggered L-cell electrical activity, increased intracellular calcium, and activated a depolarizing current that was blocked by the TRPC3 inhibitor Pyr3. TAK-875 triggered GLP-1 secretion was Pyr3 sensitive, suggesting that the TRPC3 channel links FFA1 activation to calcium elevation and GLP-1 release in L-cells. GPBAR1 agonist triggered PKA dependent L-type Ca2+ current activation and action potential firing in L-cells. The combination of TAK-875 and a GPBAR1 agonist triggered synergistic calcium elevation and GLP-1 secretory responses. CONCLUSIONS: FFA1 and GPBAR1 activation individually increased electrical activity in L-cells by recruiting pathways that include activation of TRPC3 and L-type voltage-gated Ca2+ channels. Synergy between the pathways activated downstream of these receptors was observed both at the level of Ca2+ elevation and GLP-1 secretion. PMID- 29167063 TI - Intramuscular administration potentiates extended dwell time of mesenchymal stromal cells compared to other routes. AB - BACKGROUND: Mesenchymal stromal cells (MSCs) offer great potential for diverse clinical applications. However, conventional systemic infusion of MSCs limits their therapeutic benefit, since intravenously (IV) infused cells become entrapped in the lungs where their dwell time is short. METHODS: To explore possible alternatives to IV infusion, we used in vivo optical imaging to track the bio-distribution and survival of 1 million bioluminescent MSCs administered IV, intraperitoneally (IP), subcutaneously (SC) and intramuscularly (IM) in healthy athymic mice. RESULTS: IV-infused MSCs were undetectable within days of administration, whereas MSCs implanted IP or SC were only detected for 3 to 4 weeks. In contrast, MSCs sourced from human umbilical cord matrix or bone marrow survived more than 5 months in situ when administered IM. Long-term survival was optimally achieved using low passage cells delivered IM. However, MSCs could undergo approximately 30 doublings before their dwell time was compromised. Cryo preserved MSCs administered IM promptly after thaw were predominantly cleared after 3 days, whereas equivalent cells cultured overnight prior to implantation survived more than 3 months. DISCUSSION: The IM route supports prolonged cell survival of both neo-natal and adult-derived MSCs, although short-term MSC survival was comparable between all tested routes up to day 3. IM implantation presents a useful alternative to achieve clinical benefits from prolonged MSC dwell time at a homeostatic implant site and is a minimally invasive delivery route suitable for many applications. However, optimized thaw protocols that restore full biological potential of cryo-preserved MSC therapies prior to implantation must be developed. PMID- 29167064 TI - The effect of adjuvant chemotherapy on symptom burden and quality of life over time; a preliminary prospective observational study using individual data of patients aged >=70 with early stage invasive breast cancer. AB - OBJECTIVES: We aim to assess short and long term effects of chemotherapy on patient-reported quality of life (QOL) and patient versus clinician symptom reporting in older patients with breast cancer adjusted for tumour and aging parameters. MATERIAL AND METHODS: In this prospective, multicentre, non interventional, observational study, women aged >=70years were enrolled after surgery and assigned to a TC chemotherapy (docetaxel and cyclophosphamide) group or a control group depending on their planned adjuvant treatment. Longitudinal multivariate models were used to assess the statistical and minimal clinically important difference (MCID) in the impact of TC chemotherapy over time on QOL and symptom burden adjusted for baseline aging and tumour parameters. Statistical significance was set at 5% and MCID at 10 points. RESULTS: In total, 57 patients were enrolled in the chemotherapy and 52 patients in the control group. Within the chemotherapy group, clinical deterioration was reported at 3months for Fatigue (17.73), Dyspnoea (17.05), Diarrhoea (12.06) and Appetite Loss (17.05) scores (all p<0.001). However, the scores had returned to baseline (or even better for Role Functioning) at year 1. No clinical deterioration was reported in the control group. Symptom scores as reported by patients were significantly (p<0.05) higher than those reported by the clinicians, even more so for Fatigue, Dyspnoea, and Pain. CONCLUSION: Our results show that symptom burden and diminished QOL in an older breast cancer population receiving adjuvant TC chemotherapy are short-lived and disappear after a while with no long-term differences compared to a similar population not receiving chemotherapy. PMID- 29167066 TI - Method for quantitative detection of FAM19A4 by flow cytometry using latex beads as solid carrier. AB - FAM19A4 (family with sequence similarity 19 member A4; also TAFA4) is a classical secretory protein expressed mainly in the central nervous system and upregulated significantly in lipopolysaccharide (LPS)-stimulated monocytes and macrophages. It is a novel cytokine ligand of formyl peptide receptor 1 (FPR1), showing chemotactic activities on macrophages and promoting the phagocytosis capacity and the release of reactive oxygen species (ROS) by macrophages upon zymosan stimulation. Based on the same detection principle as enzyme-linked immunosorbent assay (ELISA), we developed a sandwich immunoassay for quantitative detection of FAM19A4 in biological fluids by flow cytometry, with latex beads as solid carrier. The method showed good performance in a wide range of 39-10,000 pg/mL and possessed excellent specificity, good precision, and favorable recovery in several different matrices. Native FAM19A4 secreted by phorblo 12-myristate 13 acetate (PMA) and LPS stimulated THP-1 cells could also be detected by this method. This method will be much helpful to FAM19A4 studies. PMID- 29167065 TI - A Systematic Review of Practice Guidelines and Recommendations for Discontinuation of Cholinesterase Inhibitors in Dementia. AB - Cholinesterase inhibitors (ChEIs) are the primary pharmacological treatment for symptom management of Alzheimer disease (AD), but they carry known risks during long-term use, and do not guarantee clinical effects over time. The balance of risks and benefits may warrant discontinuation at different points during the disease course. Indeed, although there is limited scientific study of deprescribing ChEIs, clinicians routinely face practical decisions about whether to continue or stop medications. This review examined published practice recommendations for discontinuation of ChEIs in AD. To characterize the scientific basis for recommendations, we first summarized randomized controlled trials of ChEI discontinuation. We then identified practice guidelines by professional societies and in textbooks and classified them according to 1) whether they made a recommendation about discontinuation, 2) what the recommendation was, and 3) the proposed grounds for discontinuation. There was no consensus in guidelines and textbooks about discontinuation. Most recommended individualized discontinuation decisions, but there was essentially no agreement about what findings or situations would warrant discontinuation, or even about what domains to consider in this process. The only relevant domain identified by most guidelines and textbooks was a lack of response or a loss of effectiveness, both of which can be difficult to ascertain in the course of a progressive condition. Well-designed, long-term studies of discontinuation have not been conducted; such evidence is needed to provide a scientific basis for practice guidelines. It seems reasonable to apply an individualized approach to discontinuation while engaging patients and families in treatment decisions. . PMID- 29167067 TI - Autoclavable physically-crosslinked chitosan cryogel as a wound dressing. AB - Moist wounds were known to heal more rapidly than dry wounds. Hydrogel wound dressings were suitable for the moist wound healing because of their hyperhydrous structure. Chitosan was a strong candidate as a base material for hydrogel wound dressings because the polymer had excellent biological properties that promoted wound healing. We previously developed physically-crosslinked chitosan cryogels, which were prepared solely by freeze-thawing of a chitosan-gluconic acid conjugate (CG) aqueous solution, for wound treatment. The CG cryogels were disinfected by immersing in 70% ethanol before applying to wounds in our previous study. In the present study, we examined the influence of autoclave sterilization (121 degrees C, 20 min) on the characteristics of CG cryogel because complete sterilization was one of the fundamental requirements for medical devices. We found that optimum value of gluconic acid content of CG, defined as the number of the incorporated gluconic acid units per 100 glucosamine units of chitosan, was 11 for autoclaving. An increased crosslinking level of CG cryogel on autoclaving enhanced resistance of the gels to enzymatic degradation. Furthermore, the autoclaved CG cryogels retained favorable biological properties of the pre autoclaved CG cryogels in that they showed the same hemostatic activity and efficacy in repairing full-thickness skin wounds as the pre-autoclaved CG cryogels. These results showed the great potential of autoclavable CG cryogels as a practical wound dressing. PMID- 29167068 TI - Three-dimensional morphology of lunate surface in hip dysplasia: Theoretical implications for periacetabular osteotomy. AB - BACKGROUND: The objective of this study was to evaluate three-dimensional morphology of acetabular lunate surface in patients with dysplastic hip using three-dimensional computed tomography (CT), and to compare the lunate surface morphology between the normal and dysplastic hips. METHODS: Sixty seven dysplastic hips in symptomatic patients and 61 normal hips in healthy volunteers who underwent three-dimensional CT scanning were included in this study. The size and shape of the lunate surface was measured with a fully automated imaging technique using Mimics16.0 software; lunate surface morphology was compared between the normal and dysplastic hips on the radial spherical coordinate system. RESULTS: A general trend of inferomedial rotation of the lunate surface was observed in dysplastic hips. Dysplastic hips showed a remarkable decrease in total absolute and relative size of the lunate surface as compared to that in normal hips. The dysplastic hips were divided into four groups: superior area decrease group (SD); anterosuperior area decrease group (ASD); global area decrease group (GD); global area increase group (GI). The arc of the global increase (GI) subgroup (26.86%) was increased, while that of the remaining three subgroups was decreased as compared to that in the normal acetabulum group. CONCLUSION: Three-dimensional information and fundamental morphological features of the lunate surface in dysplastic hips were significantly different from those in the normal group. These findings may aid precise computational biomechanical analysis, preoperative planning for periacetabular osteotomy (PAO), achievement of satisfactory cartilaginous congruency, and judgment of postoperative prognosis in addition to postoperative treatment evaluation. PMID- 29167069 TI - Association between brain and low back pain. AB - Most chronic low back pain includes elements of nociceptive pain, neuropathic pain, and nonorganic pain. We conducted screening for nonorganic pain with use of the Brief Scale for Psychiatric Problems in Orthopaedic Patients (BS-POP), which is simple and can be used for multidimensional assessment. Research on pain areas using functional magnetic resonance imaging (fMRI) and positron emission tomography has shown that the dopamine system contributes to the pathology of chronic low back pain. Chronic low back pain patients show decreased activation of the anterior cingulate cortex, prefrontal cortex, and nucleus accumbens. Given that both the anterior cingulate cortex and prefrontal cortex belong to the descending inhibitory system, and that the nucleus accumbens, which is involved in the dopamine system, releases MU-opioids that act to relieve pain, decreased activation in these three brain regions may be related to decreased function of the descending inhibitory system. A pathological condition that can be explained at the molecular biological level clearly exists between chronic low back pain and psychosocial factors, and investigations of a pathological condition of chronic low back pain including brain function are needed. PMID- 29167070 TI - Performance of Ultrafast DCE-MRI for Diagnosis of Prostate Cancer. AB - RATIONALE AND OBJECTIVES: This study aimed to test high temporal resolution dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) for different zones of the prostate and evaluate its performance in the diagnosis of prostate cancer (PCa). Determine whether the addition of ultrafast DCE-MRI improves the performance of multiparametric MRI. MATERIALS AND METHODS: Patients (n = 20) with pathologically confirmed PCa underwent preoperative 3T MRI with T2-weighted, diffusion-weighted, and high temporal resolution (~2.2 seconds) DCE-MRI using gadoterate meglumine (Guerbet, Bloomington, IN) without an endorectal coil. DCE MRI data were analyzed by fitting signal intensity with an empirical mathematical model to obtain parameters: percent signal enhancement, enhancement rate (alpha), washout rate (beta), initial enhancement slope, and enhancement start time along with apparent diffusion coefficient (ADC) and T2 values. Regions of interests were placed on sites of prostatectomy verified malignancy (n = 46) and normal tissue (n = 71) from different zones. RESULTS: Cancer (alpha = 6.45 +/- 4.71 s-1, beta = 0.067 +/- 0.042 s-1, slope = 3.78 +/- 1.90 s-1) showed significantly (P <.05) faster signal enhancement and washout rates than normal tissue (alpha = 3.0 +/- 2.1 s-1, beta = 0.034 +/- 0.050 s-1, slope = 1.9 +/- 1.4 s-1), but showed similar percentage signal enhancement and enhancement start time. Receiver operating characteristic analysis showed area under the curve for DCE parameters was comparable to ADC and T2 in the peripheral (DCE 0.67-0.82, ADC 0.80, T2 0.89) and transition zones (DCE 0.61-0.72, ADC 0.69, T2 0.75), but higher in the central zone (DCE 0.79-0.88, ADC 0.45, T2 0.45) and anterior fibromuscular stroma (DCE 0.86-0.89, ADC 0.35, T2 0.12). Importantly, combining DCE with ADC and T2 increased area under the curve by ~30%, further improving the diagnostic accuracy of PCa detection. CONCLUSION: Quantitative parameters from empirical mathematical model fits to ultrafast DCE-MRI improve diagnosis of PCa. DCE-MRI with higher temporal resolution may capture clinically useful information for PCa diagnosis that would be missed by low temporal resolution DCE-MRI. This new information could improve the performance of multiparametric MRI in PCa detection. PMID- 29167071 TI - Therapeutic response analysis in dogs with naturally occurring osteoarthritis. AB - OBJECTIVE: Reporting the rate of positive (+) and negative (-) responders based on an objective outcome measure of pain-related functional disability/lameness in dogs with naturally occurring osteoarthritis (OA), and the relationship between initial lameness severity and the odds of being a (+) responder. STUDY DESIGN: Retrospective analysis of published peer-reviewed clinical trials in dogs with naturally occurring OA. ANIMALS: Dogs (n = 213) with hip and/or stifle afflicted joints. METHODS: A responder analysis was undertaken using a previously determined cut-off value of +/-2.0% of body weight using the peak of vertical force (PVF). Among the selected trials, PVF was acquired under similar conditions. Therapeutic approaches were therapeutic diets, natural health products and nonsteroidal anti-inflammatory drugs. RESULTS: Among dogs receiving a therapeutic approach as described above (n = 121), 62.8% [95% confidence interval, 53.9-70.9] were defined as (+) responders, whereas 11.6% [7.0-18.5] were (-) responders, accounting for a net (+) response rate by 51.2% [42.0-60.4]. In dogs receiving a negative control (n = 92), the net (+) response rate was 1.1% [0.0-5.9]. The number needed to treat was 4, and the effect size 0.7 [0.4-1.0]. The odds ratio of being a (+) responder under the therapeutic approaches was 2.85 [1.57-5.17] (p < 0.001). For every less severe lameness manifested with an increment in PVF by 1% body weight, the chance of being a (+) responder following treatment decreased by 9% (odds ratio 0.91 [0.86-0.97], p = 0.006). CONCLUSION AND CLINICAL RELEVANCE: The rate of (+) responder optimizes decision making for the management of pain-related clinical signs of OA. Evidence-based medicine was further supported by clinical metrics based on an objective outcome measure of pain-related functional disability/lameness. This study also revealed that dogs with a mild lameness are less prone to be improved, emphasizing the need to carefully manage OA dogs in spite of a more subtle affliction. PMID- 29167072 TI - Induction of anaesthesia with remifentanil after bolus midazolam administration in Landrace/Large White swine. AB - OBJECTIVE: To investigate an alternative combination for anaesthesia induction in swine. STUDY DESIGN: Randomized, 'blinded' experimental study. ANIMALS: Forty five Landrace/Large White swine weighing 20.0+/-1.5 kg. METHODS: Pulse oximetry, heart rate (HR) and blood pressure were measured after premedication with ketamine, midazolam and atropine as well as after intubation following induction with a fixed dose of 0.2 mg kg-1 midazolam combined with 1, 2, 3, 4 or 5 MUg kg-1 remifentanil (groups R1, R2, R3, R4 and R5, respectively). Intubation was evaluated using a numerical scoring system assessing jaw relaxation, resistance to the laryngoscope, vocal cord position, vocal cord movement and response to intubation. The time required to intubate and necessity for an additional midazolam dose were recorded. Baseline and post-intubation variables were compared with paired t tests, whereas for differences between the remifentanil groups the Spearman's rank correlation coefficient was estimated. Multivariate regression analysis was performed to disentangle the effect of remifentanil dose and the additional midazolam. RESULTS: Higher dose of remifentanil was associated with better vocal cord position (p<0.001), better response to intubation (p<0.001), shorter time required for intubation (p=0.030) and less frequent necessity for additional administration of midazolam (p=0.004). In total, 39.5% of the animals required additional midazolam. In groups R1, R4 and R5, there were decreases in HRs (p=0.009, p=0.008 and p=0.032, respectively) between baseline and post-intubation phase; in groups R3 and R4, there were decreases in systolic blood pressure (p=0.040 and p=0.019, respectively). In the multivariate analysis, remifentanil dose was not associated with the observed changes in haemodynamic variables. One animal developed apnoea and four electrocardiographic anomalies; all resolved without pharmaceutical interventions. CONCLUSIONS AND CLINICAL RELEVANCE: A combination of 0.2 mg kg-1 midazolam with 4 or 5 MUg kg-1 remifentanil may provide an alternative method of anaesthesia induction for swine.

PMID- 29167074 TI - Effects of Thermomechanical Stimulation during Vaccination on Anxiety, Pain, and Satisfaction in Pediatric Patients: A Randomized Controlled Trial. AB - PURPOSE: Vaccination can be a significant source of pain for pediatric patients, which could result in fear of medical procedures and future reluctance to seek medical care. It is important for nurses to provide pain prevention during these procedures. This study sought to measure the impact of an intervention combining cold and vibration on pain scores during routine pediatric immunization. DESIGN AND METHODS: A prospective, open-label, randomized controlled trial to examine the effectiveness of the Buzzy device (thermomechanical stimulation) compared to no intervention (control group) in reducing child-reported pain during routine immunization. The Wong Baker Faces scale was used to collect child, parent, and observer reported anxiety and pain. Parents reported satisfaction with the procedure and overall office visit. RESULTS: Fifty children between the ages of 3 and 18 were included in the present analysis. Mean child-reported pain scores were significantly lower in the group receiving thermomechanical stimulation compared to control (3.56 vs 5.92, p=0.015). Buzzy did not impact child-reported anxiety or how much pain the child expected. Parent-reported satisfaction did not vary significantly between groups, but was strongly associated with parent reported pain scores. CONCLUSIONS: Thermomechanical stimulation with the Buzzy device significantly reduced pain during pediatric immunization over a wide range of ages compared to control, but did not impact pre-procedure anxiety. PRACTICE IMPLICATIONS: The Buzzy device is an easy to implement intervention to reduce pediatric pain during vaccination. It may have the greatest impact in younger children but could be offered during all immunizations. PMID- 29167075 TI - Provider Beliefs Regarding Early Mobilization in the Pediatric Intensive Care Unit. AB - PURPOSE: Critically ill patients are at risk for short and long term morbidity. Early mobilization (EM) of critically ill adults is safe and feasible, with improvement in outcomes. There are limited studies evaluating EM in pediatric critical care patients. Provider beliefs and concerns must be evaluated prior to EM implementation in the pediatric intensive care unit (PICU). DESIGN AND METHODS: A survey was distributed to PICU providers assessing beliefs and concerns with regards to EM of PICU patients. RESULTS: Seventy-one providers responded. Most staff believed EM would be beneficial. The largest perceived benefits were decreased length of both stay and mechanical ventilation. The largest perceived concerns were risk of both endotracheal tube and central venous catheter dislodgement. Surveyed clinicians felt significantly more comfortable mobilizing the oldest as compared to the youngest patients (p<0.0001). Clinicians also felt significantly more comfortable mobilizing patients receiving invasive mechanical ventilation in the oldest as compared to the youngest patients (p<0.0001). CONCLUSION: There is clear benefit to the EM of adult ICU patients, with evidence supporting its safety and feasibility. As pediatric patients pose different challenges, it is imperative to understand provider concerns prior to the implementation of EM. Our research demonstrates similar concerns between adult and pediatric programs, with the addition of significant concern surrounding EM in very young children. PRACTICE IMPLICATIONS: Understanding pediatric specific concerns with regards to EM will allow for the proper development and implementation of pediatric EM programs, allowing us to assess safety, feasibility, and ultimately outcomes. PMID- 29167076 TI - The Convergence of Two Epidemics: Vitamin D Deficiency in Obese School-aged Children. AB - PROBLEM: Vitamin D deficiency (VDD) and obesity are two interrelated global epidemics that affect school-aged children. This article will review the relationship between VDD and obesity in school-aged children and implications it has for the pediatric nurse (PN). ELIGIBILITY CRITERIA: Original articles of studies, review articles and meta-analyses were selected from the past 5years and pooled for review. These included obese school-aged children who had vitamin D insufficiency. The latest guidelines concerning the issue were also included. SAMPLE: Children 6-12years of age with obesity and vitamin D insufficiency. RESULTS: This review strongly implies obesity in children being a strong risk factor for VDD. Prevention of VDD starts with lifestyle changes and adequate dietary intake of fortified foods and current screening recommendations for VDD are inconsistent. Vitamin D supplementation is recommended with inadequate intake or deficient serum 25-hydroxyvitamin D levels or signs of hypocalcemia. Supplementation doses differ based on whether VDD is being prevented or being treated and in obese children, the Endocrine Society recommends a dose that is two to three times higher than for normal weight children. Subclinical signs and symptoms of VDD include musculoskeletal pain, fractures, reduced bone density and reduced immunity. CONCLUSIONS: Whereas obesity is a strong risk factor for VDD, more research is needed to clarify the role of VDD as a risk factor for obesity. IMPLICATIONS: The PN plays an essential role in preventing, screening for, assessing for, treating and counseling on VDD in obese school-aged children. PMID- 29167077 TI - The Effects of Breastfeeding in Infants With Phenylketonuria. AB - PURPOSE: In the early years of phenylketonuria (PKU) treatment, mothers and healthcare professionals often decide to discontinue breastfeeding after the diagnosis of PKU in infants. It was believed to be the only effective way to monitor the infant's intake and allow for precise titration and measurement of the intake of phenylalanine (Phe). In the early 1980s, with the determination of low concentration of Phe in breast milk, breast milk supplemented with Phe-free formula has become an acceptable dietary treatment for infants with PKU. Today, breastfeeding is encouraged and well established in PKU patients. The aim of the present study is to investigate the prevalence and duration of breastfeeding, the effect of breastfeeding on serum Phe levels, and weight gain in infants with PKU. DESIGN AND METHODS: Data were collected from chart reviews. Medical records of 142 children with PKU diagnosed via the national neonatal screening program were analyzed retrospectively. RESULTS: Of the 41 infants with complete medical records, 40 (97.6%) were breastfed following delivery whereas only one (2.4%) was bottle fed. After the diagnosis, breastfeeding was continued in 25 (61%) infants with phenylalanine-free amino acid based protein substitute. The mean duration of breastfeeding was 7.4+/-4.0 (1-15) months. Serum Phe concentration of breastfed infants (280+/-163 MUmol/L) was significantly lower than non-breastfed infants (490+/-199 MUmol/L) (p<0.001). Mean monthly weight gain in the first year of life was significantly higher in breastfed patients (493+/-159 g/month) compared to non-breastfed patients (399+/-116 g/month) (p=0.046). CONCLUSION: In the first year of life, weight gain and serum Phe levels were more favorable in breastfed infants with PKU compared to non-breastfed infants with PKU. PMID- 29167078 TI - Implementation of Pediatric Early Warning Score; Adherence to Guidelines and Influence of Context. AB - PURPOSE: To describe data of Pediatric Early Warning Score (PEWS) registrations and to evaluate the implementation of PEWS by examining adherence to clinical guidelines based on measured PEWS, and to relate findings to work context. DESIGN AND METHODS: PEWS, as a part of a concept called Early Detection and Treatment Children (EDT-C) was implemented at three wards at a Children's Hospital in Sweden. Data were collected from the Electronic Patient Record (EPR) retrospectively to assess adherence to guidelines. The Alberta Context Tool (ACT) was used to assess work context among healthcare professionals (n=109) before implementation of EDT-C. RESULTS: The majority of PEWS registrations in EPR were low whereas 10% were moderate to high. Adherences to ward-specific guidelines at admission and for saturation in respiratory distress were high whereas adherence to pain assessment was low. There were significant differences in documented recommended actions between wards. Some differences in leadership and evaluation between wards were identified. CONCLUSIONS: Evaluation of PEWS implementation indicated frequent use of the tool despite most scores being low. High scores (5 9) occurred 28 times, which may indicate that patients with a high risk of clinical deterioration were identified. Documentation of the consequent recommended actions was however incomplete and there was a large variation in adherence to guidelines. Contextual factors may have an impact on adherence. PRACTICE IMPLICATIONS: EDT-C can lead to increased knowledge about early detection of deterioration, strengthen nurses as professionals, optimize treatment and teamwork and thereby increase patient safety for children treated in hospitals. PMID- 29167079 TI - Use of Theory to Examine Health Responsibility in Urban Adolescents. AB - : The study's purpose was to examine the factors that may influence health responsibility among adolescents. More specifically, this study examined relationships among health responsibility, resilience, neighborhood perception, social support, and health promoting behaviors in adolescents, between the ages of 13 and 18years old. The Health Promotion Model was used as the theoretical framework. This study empirically tested theoretical relationships postulated in the literature between health responsibility and the variables: (a) resilience (b) social support (c) neighborhood perception (d) social support and (e) health promoting behaviors. DESIGN/METHODS: A correlational study design was used. A convenience sample of 122 adolescents in an urban setting completed questionnaires assessing health responsibility, resilience, social support, neighborhood perception, health promoting behaviors, and a demographic questionnaire. Pearson correlations were used to examine relationships among variables. RESULTS: A statistically significant relationship was found between health responsibility and healthy promoting behaviors (r=0.733, p<0.001) and between health responsibility and neighborhood perception (r=0.163, p<0.01). No relationships were found between the dependent variable of health responsibility and the independent variables of resilience and social support in this population. CONCLUSIONS: Study findings help contribute to the body of knowledge regarding the factors that influence health responsibility among urban adolescents to promote adoption and maintenance of healthy behaviors among this population. PRACTICE IMPLICATIONS: Nurses need to educate adolescents to provide them with a good understanding of the consequences of health behaviors so that they can assess their own risk and make responsible, healthy choices. PMID- 29167080 TI - Psychosocial Care Models for Families of Critically Ill Children in Pediatric Emergency Department Settings: A Scoping Review. AB - PROBLEM: Critical illness in children is a significant and stressful life event for families. Within pediatric emergency department (ED) settings it is acknowledged that these crises are challenging for both the families of these children, and for the clinical staff treating the child. Literature recommends routine care should include an offer to the family to be present with their critically ill child, however there is a lack of clarity regarding specific family care models or evidence-based interventions to guide clinical practice. ELIGIBILITY CRITERIA: Peer reviewed articles written in English, published between 2006 and 2016, proposing or testing psychosocial care models in pediatric (or mixed) emergency settings. SAMPLE: Nine articles met inclusion criteria. RESULTS: Search results showed limited evidence available in the literature at this time. Thematic analysis of article content and proposed model showed strong support for the benefit of family presence, including shifting the family role from passive to active, needing to be inclusive of the psychological impact of critical health events, importance of multidisciplinary education, and the need for additional exploratory and empirical research to evaluate and refine proposed care models. CONCLUSIONS: Pediatric emergency health events are challenging for both families and staff, and care models provide staff with a consistent, evidence-informed approach to caring for families in challenging situations. IMPLICATIONS: There is a need to find common ground from specific discipline guidelines into a multidisciplinary team approach for the care of families within emergency care. PMID- 29167081 TI - Randomized Trial Evaluating the Effectiveness of a Leg Crossing and Muscle Tensing Technique on Decreasing Vasovagal Symptoms Among Pediatric and Young Adult Patients Undergoing Peripheral IV Catheter Insertion. AB - : Peripheral intravenous (PIV) catheter insertion is a common procedure that can cause vasovagal symptoms. Lower extremity muscle tensing techniques decrease these symptoms in adults. However, there are no studies examining this technique in the pediatric population. OBJECTIVE: This study aims to determine whether pediatric patients are able to perform the technique and to determine the effects of this technique on vasovagal symptoms in a pediatric population. DESIGN, SETTING, PARTICIPANTS: A parallel-group randomized controlled trial was conducted with 28 patients cared for in a pediatric surgery unit. INTERVENTION: Patients randomized to the experimental group performed the leg crossing and muscle tensing technique during PIV placement. Patients in the control group received standard care during PIV placement. PRIMARY OUTCOME MEASURE: The primary outcome measure was the frequency of experiencing at least one vasovagal sign or symptom which included nausea, vomiting, dizziness, pallor, sweating/diaphoresis, and fainting. RESULTS: Patients randomized to perform the technique were able to perform it without difficulty. There was a lower frequency of experiencing vasovagal symptoms among patients in the experimental group (15%) compared to patients in the control group (62.5%) (Fisher's exact test, p=0.02). The number of vasovagal symptoms experienced by patients in the experimental group (M=0.3) was significantly lower than the number of vasovagal symptoms experienced by patients in the control group (M=1.13), t(26)=2.302, p=0.03. CONCLUSION: A leg crossing technique is a low cost, low risk, and effective strategy to teach to pediatric patients resulting in reducing vasovagal symptoms. PMID- 29167082 TI - Disparities in Health Literacy and Healthcare Utilization among Adolescents and Young Adults with Chronic or End-stage Kidney Disease. AB - PURPOSE: Low health literacy adversely affects health outcomes in adults with chronic kidney disease. The current study examined associations between limited/inadequate health literacy and health services utilization among adolescents and young adults (AYA) with chronic or end-stage kidney disease (CKD or ESKD). DESIGN AND METHODS: This was a retrospective cohort study that enrolled patients from both the pediatric- and adult-focused nephrology clinics of a major university hospital. Demographic information, patients' health literacy and numeracy skills (Newest Vital Sign), and health services utilization (emergency department visits, preventable hospitalizations, total hospitalizations, and length of stay in the hospital) were evaluated. A negative binomial regression model for counts tested the association between AYA patients' literacy/numeracy skills and health services utilization. RESULTS: The study enrolled 142 participants, 66 (46.5%) patients from adult nephrology and 76 (53.5%) from pediatric nephrology clinics, with a mean age of 20.8+/-5.60years (range 12-31). Half of the sample (n=72, 51%) had limited health literacy skills. Health literacy/numeracy level was not significantly associated with total hospitalizations, preventable hospitalizations, emergency department (ED) visits, or length of hospital stay. However, public insurance/self-pay, minority race, and kidney transplant/dialysis diagnoses were associated with more preventable hospitalizations. CONCLUSIONS: Among AYA with CKD/ESKD, there were no differences between the low and adequate health literacy groups on health care utilization outcomes when modeling clinical outcomes (total hospitalizations, preventable hospitalizations, ED visits, and length of hospital stay) after adjusting for demographics and disease type. This suggests that other factors warrant consideration in healthcare utilization rates. PMID- 29167083 TI - The Effect of Diagnostic Blood Loss on Anemia and Transfusion Among Postoperative Patients With Congenital Heart Disease in a Pediatric Intensive Care Unit. AB - PURPOSE: To evaluate whether diagnostic blood loss can lead to anemia and consequent blood transfusion among postoperative patients with congenital heart disease (CHD) in the pediatric intensive care unit (PICU). DESIGN AND METHODS: This prospective observational study was conducted in a university-affiliated tertiary hospital between January and August 2016. CHD patients aged <12years, undergoing cardiac surgery, with a PICU stay >48h were included (n=205). Multivariate logistic regression analyses were used to determine the effect of diagnostic blood loss on anemia and transfusion. RESULTS: The mean daily phlebotomy volume was 5.40+/-1.94mL/d during the PICU stay (adjusted for body weight, 0.63+/-0.36mL/kg/d). Daily volume/kg was associated with cyanotic CHD, Pediatric Risk of Mortality III score, and Pediatric Logistic Organ Dysfunction (PELOD)-2 score. In total, 101 (49.3%) patients presented with new or more severe anemia after admission to PICU, which was not associated with phlebotomy volume. Forty-one (20.0%) children received one or more RBC transfusions during their PICU stay. Multivariate analysis indicated that PELOD-2 score>5, new or more severe anemia, and daily volume/kg of phlebotomy >0.63mL/kg/d were significantly associated with transfusion after 48h of admission to PICU. CONCLUSIONS: Our findings indicate that diagnostic blood loss is not related to postoperative anemia in children with CHD; however, this factor does correlate with blood transfusion, since it somewhat reflects the severity of illness. PRACTICE IMPLICATIONS: Strategies should be applied to reduce diagnostic blood loss, as appropriate. PMID- 29167084 TI - Parent's Experiences of Their Children Suffering Febrile Seizures. AB - PURPOSE: To explore parents' experiences of their child suffering febrile seizures. DESIGN AND METHOD: Seven mothers and four fathers with experience of one or several febrile seizures in their children were interviewed. A qualitative content analysis with an inductive approach was performed. RESULT: Five themes emerged; emotional experiences, in terms of anxiety and fear, and need for control, need for support, need for acknowledgement and need for comfort. Professional assurance and support from healthcare staff was considered important to help parents handle the situation. CONCLUSION: Febrile seizure caused anxiety due to parents' lack of comprehension about the event and how to act during the seizure. PRACTICE IMPLICATIONS: The pediatric nurse plays an important role in gaining the trust of and supporting parents whose children have suffered febrile seizures. They can alleviate concerns that arise, and also generate assured and well informed parents, who are better prepared to deal with recurrent febrile seizures. PMID- 29167085 TI - Factors Leading to Persistent Postsurgical Pain in Adolescents Undergoing Spinal Fusion: An Integrative Literature Review. AB - PROBLEM: Adolescent idiopathic scoliosis (AIS) is the most common spinal deformity among children and adolescents and the most frequent reason for corrective spinal fusion (SF). Of the children and adolescents who undergo SF, a significant number will experience persistent postoperative pain (PPP). This integrative literature review was conducted to identify and synthesize perioperative factors that may contribute to risk of developing PPP. ELIGIBILITY CRITERIA: Articles which addressed PPP within the last 10years and primary research on postoperative pain outcomes in adolescents after SF were selected for review. SAMPLE: 15 articles which met eligibility criteria were included. RESULTS: Preoperative pain intensity was the most significant factor identified in the development of PPP and increased postoperative pain. Social function and psychological factors also have role in the development of PPP. There were no theoretical models or frameworks for evaluating PPP incidence in adolescent with AIS after SF. CONCLUSIONS: Perioperative factors such as, preoperative pain, correction magnitude, pain coping, anxiety and social functioning are vital to understanding a child's risk of PPP following SF. There is a need for theoretically-based studies to assess PPP among children and adolescents with AIS after SF surgery. IMPLICATIONS: The Biobehavioral Pain Network (BPN) model was proposed, to encompass biological, social and psychological domains which may be responsible for incidence of PPP in children undergoing SF. Such a model can be used to systematically develop and evaluate personalized postoperative pain management strategies for this patient population. PMID- 29167086 TI - Outcomes of Depression Screening Among Adolescents Accessing School-based Pediatric Primary Care Clinic Services. AB - PURPOSE: Implementation of routine Patient Health Questionnaires (PHQ-9) screening among adolescents aged 12-18year, accessing school-based pediatric primary care clinic services for identification of adolescents at potential risk for Major Depressive disorder (MDD). DESIGN AND METHODS: Retrospective chart review (N=256 cases) documented PHQ-9 depression screening outcomes among adolescents accessing school-based pediatric primary care clinic services for episodic illness and wellness visits. Data analyses included descriptive statistical methods. RESULTS: Chart review included 137 (53.5%) females and 119 (46.5%) males. PHQ-9 depression screening was identified for 56.3% (n=144) of charts with scores >=10 for 12.5% (n=18) among those screened. Mental health referrals were made for 83.3% (n=15) with PHQ-9 scores >=10. Dysthymia related concerns were reported among 20.1% (n=29) of which 55.2% (n=16) received mental health referrals. Female adolescents reported more sleep problems (chi2=9.174, p=0.002) and tiredness (chi2=6.165, p=0.013) than males. The 15-18year age group (chi2=5.443, p=0.020) was more likely to experience sleep problem and low self esteem than 12-14year age group (chi2=5.143, p=0.023). CONCLUSION: Implementation of PHQ-9 depression screening protocol identified MDD among adolescent accessing pediatric school-based primary care clinic services facilitating referrals to mental health providers, potentially improving morbidity and mortality among adolescents. PRACTICE IMPLICATIONS: MDD is common among adolescents and associated with functional impairments and increased morbidity and mortality. Due to its high prevalence, it is imperative to improve screening and treatment access in this population via school-based clinics. PMID- 29167088 TI - Network Neuroscience Theory of Human Intelligence. AB - An enduring aim of research in the psychological and brain sciences is to understand the nature of individual differences in human intelligence, examining the stunning breadth and diversity of intellectual abilities and the remarkable neurobiological mechanisms from which they arise. This Opinion article surveys recent neuroscience evidence to elucidate how general intelligence, g, emerges from individual differences in the network architecture of the human brain. The reviewed findings motivate new insights about how network topology and dynamics account for individual differences in g, represented by the Network Neuroscience Theory. According to this framework, g emerges from the small-world topology of brain networks and the dynamic reorganization of its community structure in the service of system-wide flexibility and adaptation. PMID- 29167087 TI - Eating Behaviors, Weight Bias, and Psychological Functioning in Multi-ethnic Low income Adolescents. AB - PURPOSE: The purposes of this study were to: 1) Describe the incidence of disordered eating, weight bias, body dissatisfaction, and psychological distress, 2) Examine the relationship between sociodemographic variables (gender, ethnicity, and income) and disordered eating, weight bias, body dissatisfaction, and psychological distress in a sample of low-income adolescents. DESIGN AND METHODS: A cross-sectional study was conducted with 105 adolescents from low income neighborhoods. Participants completed self-report questionnaires to assess eating behaviors, weight bias, body dissatisfaction, and psychological functioning. Height and weight were measured, and information on household income was collected. RESULTS: The participant's mean age was 16.31 (SD=2.8) years, 66% female, 47% Hispanic, and 46% African American. The mean annual income was $17,018 (SD=11,355). Twenty-eight percent self-reported having some form of disordered eating, and 15% reported an eating disorder. The group with eating disorder reported the highest levels of weight bias (M=93.4, SD=109.6), body dissatisfaction (M=94.6, SD=47.6), and psychological distress (M=1.4, SD=0.97). CONCLUSION: This study found a high prevalence of eating disorders with eating disorder participants experiencing the highest levels of weight bias and psychological distress. Future studies are needed to identify and evaluate community and school-based interventions to minimize weight bias and disordered eating. PRACTICE IMPLICATIONS: Nurses are at the forefront of healthcare and should collaborate with educators, school counselors, administrators, coaches, parents, and students, to address weight bias and disordered eating in schools by implementing school-based curriculum and policies. PMID- 29167089 TI - Predicting Unplanned Transfers to the Intensive Care Unit: A Machine Learning Approach Leveraging Diverse Clinical Elements. AB - BACKGROUND: Early warning scores aid in the detection of pediatric clinical deteriorations but include limited data inputs, rarely include data trends over time, and have limited validation. OBJECTIVE: Machine learning methods that make use of large numbers of predictor variables are now commonplace. This work examines how different types of predictor variables derived from the electronic health record affect the performance of predicting unplanned transfers to the intensive care unit (ICU) at three large children's hospitals. METHODS: We trained separate models with data from three different institutions from 2011 through 2013 and evaluated models with 2014 data. Cases consisted of patients who transferred from the floor to the ICU and met one or more of 5 different priori defined criteria for suspected unplanned transfers. Controls were patients who were never transferred to the ICU. Predictor variables for the models were derived from vitals, labs, acuity scores, and nursing assessments. Classification models consisted of L1 and L2 regularized logistic regression and neural network models. We evaluated model performance over prediction horizons ranging from 1 to 16 hours. RESULTS: Across the three institutions, the c-statistic values for our best models were 0.892 (95% CI 0.875-0.904), 0.902 (95% CI 0.880-0.923), and 0.899 (95% CI 0.879-0.919) for the task of identifying unplanned ICU transfer 6 hours before its occurrence and achieved 0.871 (95% CI 0.855-0.888), 0.872 (95% CI 0.850-0.895), and 0.850 (95% CI 0.825-0.875) for a prediction horizon of 16 hours. For our first model at 80% sensitivity, this resulted in a specificity of 80.5% (95% CI 77.4-83.7) and a positive predictive value of 5.2% (95% CI 4.5 6.2). CONCLUSIONS: Feature-rich models with many predictor variables allow for patient deterioration to be predicted accurately, even up to 16 hours in advance. PMID- 29167090 TI - Attrition from Web-Based Cognitive Testing: A Repeated Measures Comparison of Gamification Techniques. AB - BACKGROUND: The prospect of assessing cognition longitudinally and remotely is attractive to researchers, health practitioners, and pharmaceutical companies alike. However, such repeated testing regimes place a considerable burden on participants, and with cognitive tasks typically being regarded as effortful and unengaging, these studies may experience high levels of participant attrition. One potential solution is to gamify these tasks to make them more engaging: increasing participant willingness to take part and reducing attrition. However, such an approach must balance task validity with the introduction of entertaining gamelike elements. OBJECTIVE: This study aims to investigate the effects of gamelike features on participant attrition using a between-subjects, longitudinal Web-based testing study. METHODS: We used three variants of a common cognitive task, the Stop Signal Task (SST), with a single gamelike feature in each: one variant where points were rewarded for performing optimally; another where the task was given a graphical theme; and a third variant, which was a standard SST and served as a control condition. Participants completed four compulsory test sessions over 4 consecutive days before entering a 6-day voluntary testing period where they faced a daily decision to either drop out or continue taking part. Participants were paid for each session they completed. RESULTS: A total of 482 participants signed up to take part in the study, with 265 completing the requisite four consecutive test sessions. No evidence of an effect of gamification on attrition was observed. A log-rank test showed no evidence of a difference in dropout rates between task variants (chi22=3.0, P=.22), and a one way analysis of variance of the mean number of sessions completed per participant in each variant also showed no evidence of a difference (F2,262=1.534, P=.21, partial eta2=0.012). CONCLUSIONS: Our findings raise doubts about the ability of gamification to reduce attrition from longitudinal cognitive testing studies. PMID- 29167091 TI - The Effect of Aging on Physical Performance Among Elderly Manual Workers: Protocol of a Cross-Sectional Study. AB - BACKGROUND: In 2012, the Danish Parliament decided to increase retirement age. Unfortunately, elderly people working in a physically demanding environment may be rendered unable to retain the ability to adequately perform the physical requirements of their jobs, due to age-related decreases in physical performance. Therefore, increasing the retirement age may not necessarily lead to the goal of keeping everybody in the labor market for a longer time. To date, our knowledge about the variations in physical performance of the elderly workforce is limited. OBJECTIVE: In this cross-sectional study we seek to investigate the effects of aging on physical performance among elderly manual workers. METHODS: Approximately 100 Danish manual workers between 50 and 70 years of age will be recruited. The main measurement outcomes include: (1) inflammatory status from blood samples; (2) body composition; (3) lung function; (4) static and dynamic balance; (5) reaction time, precision, and movement variability during a hammering task; (6) handgrip strength, rate of force development, and force tracking; (7) estimated maximal rate of oxygen consumption; and (8) back mobility. Additionally, information regarding working conditions, physical activity levels, and health status will be assessed with a questionnaire. RESULTS: Data collection is expected to take place between autumn 2017 and spring 2018. CONCLUSIONS: This study will increase the knowledge regarding variations in physical performance in the elderly workforce and may identify potential workplace hazards. Moreover, this study might shed light on the potentially problematic decision to increase retirement age for all Danish citizens. PMID- 29167093 TI - Challenging assumptions in obesity research.

PMID- 29167092 TI - Dry Needling for Patients With Neck Pain: Protocol of a Randomized Clinical Trial. AB - BACKGROUND: Neck pain is a costly and common problem. Current treatments are not adequately effective for a large proportion of patients who continue to experience recurrent pain. Therefore, new treatment strategies should be investigated in an attempt to reduce the disability and high costs associated with neck pain. Dry needling is a technique in which a fine needle is used to penetrate the skin, subcutaneous tissues, and muscle with the intent to mechanically disrupt tissue without the use of an anesthetic. Dry needling is emerging as a treatment modality that is widely used clinically to address a variety of musculoskeletal conditions. Recent studies of dry needling in mechanical neck pain suggest potential benefits, but do not utilize methods typical to clinical practice and lack long-term follow-up. Therefore, a clinical trial with realistic treatment time frames and methods consistent with clinical practice is needed to examine the effectiveness of dry needling on reducing pain and enhancing function in patients presenting to physical therapy with mechanical neck pain. OBJECTIVE: The aim of this trial will be to examine the short- and long-term effectiveness of dry needling delivered by a physical therapist on pain, disability, and patient-perceived improvements in patients with mechanical neck pain. METHODS: We will conduct a randomized, double-blind, placebo controlled trial in accordance with the CONSORT guidelines. A total of 76 patients over the age of 18 with acute or chronic mechanical neck pain resulting from postural dysfunction, trauma, or insidious onset who are referred to physical therapy will be enrolled after meeting the eligibility criteria. Subjects will be excluded if they have previous history of surgery, whiplash in the last 6 weeks, nerve root compression, red flags, or contraindications to dry needling or manual therapy. Participants will be randomized to receive (1) dry needling, manual therapy, and exercise or (2) sham dry needling, manual therapy, and exercise. Participants will receive seven physical therapy treatments lasting 45 minutes each over a maximum of 4 weeks. The primary outcome will be disability as measured by the Neck Disability Index. Secondary outcomes include the following: pain, patient-perceived improvement, patient expectations, and successful blinding to the needling intervention. Outcome measures will be assessed at 4 weeks, 6 months, and 12 months by an assessor who is blind to the group allocation of the participants to determine the short- and long-term treatment effects. We will examine the primary aim with a two-way, repeated measures analysis of variance with treatment group as the between-subjects variable and time as the within-subjects variable. The hypothesis of interest will be the two-way group by time interaction. An a priori alpha level of .05 will be used for all analyses. RESULTS: Recruitment is currently underway and is expected to be completed by the end of 2017. Data collection for long-term outcomes will occur throughout 2017 and 2018. Data analysis, preparation, and publication submission is expected to occur throughout the final three quarters of 2018. CONCLUSIONS: The successful completion of this trial will provide evidence to demonstrate whether dry needling is effective for the management of mechanical neck pain when used in a combined treatment approach, as is the common clinical practice.

PMID- 29167102 TI - Coffee consumption and health: umbrella review of meta-analyses of multiple health outcomes. AB - Objectives To evaluate the existing evidence for associations between coffee consumption and multiple health outcomes.Design Umbrella review of the evidence across meta-analyses of observational and interventional studies of coffee consumption and any health outcome.Data sources PubMed, Embase, CINAHL, Cochrane Database of Systematic Reviews, and screening of references.Eligibility criteria for selecting studies Meta-analyses of both observational and interventional studies that examined the associations between coffee consumption and any health outcome in any adult population in all countries and all settings. Studies of genetic polymorphisms for coffee metabolism were excluded.Results The umbrella review identified 201 meta-analyses of observational research with 67 unique health outcomes and 17 meta-analyses of interventional research with nine unique outcomes. Coffee consumption was more often associated with benefit than harm for a range of health outcomes across exposures including high versus low, any versus none, and one extra cup a day. There was evidence of a non-linear association between consumption and some outcomes, with summary estimates indicating largest relative risk reduction at intakes of three to four cups a day versus none, including all cause mortality (relative risk 0.83 (95% confidence interval 0.79 to 0.88), cardiovascular mortality (0.81, 0.72 to 0.90), and cardiovascular disease (0.85, 0.80 to 0.90). High versus low consumption was associated with an 18% lower risk of incident cancer (0.82, 0.74 to 0.89). Consumption was also associated with a lower risk of several specific cancers and neurological, metabolic, and liver conditions. Harmful associations were largely nullified by adequate adjustment for smoking, except in pregnancy, where high versus low/no consumption was associated with low birth weight (odds ratio 1.31, 95% confidence interval 1.03 to 1.67), preterm birth in the first (1.22, 1.00 to 1.49) and second (1.12, 1.02 to 1.22) trimester, and pregnancy loss (1.46, 1.06 to 1.99). There was also an association between coffee drinking and risk of fracture in women but not in men.Conclusion Coffee consumption seems generally safe within usual levels of intake, with summary estimates indicating largest risk reduction for various health outcomes at three to four cups a day, and more likely to benefit health than harm. Robust randomised controlled trials are needed to understand whether the observed associations are causal. Importantly, outside of pregnancy, existing evidence suggests that coffee could be tested as an intervention without significant risk of causing harm. Women at increased risk of fracture should possibly be excluded. PMID- 29167110 TI - Blocking IDO1 Helps Shrink Bladder, Cervical Tumors.

PMID- 29167106 TI - Use of a primary care online consultation system, by whom, when and why: evaluation of a pilot observational study in 36 general practices in South West England. AB - OBJECTIVES: Evaluation of a pilot study of an online consultation system in primary care. We describe who used the system, when and why, and the National Health Service costs associated with its use. DESIGN: 15-month observational study. SETTING: Primary care practices in South West England. RESULTS: 36 General practices covering 396 828 patients took part in the pilot. The online consultation website was viewed 35 981 times over the pilot period (mean 9.11 visits per 1000 patients per month). 7472 patients went on to complete an 'e consultation' (mean 2.00 online consultations per 1000 patients per month). E consultations were mainly performed on weekdays and during normal working hours. Patient records (n=485) were abstracted for eight practices and showed that women were more likely to use e-consultations than men (64.7% vs 35.3%) and users had a median age of 39 years (IQR 30-50). The most common reason for an e-consultation was an administrative request (eg, test results, letters and repeat prescriptions (22.5%)) followed by infections/immunological issues (14.4%). The majority of patients (65.2%) received a response within 2 days. The most common outcome was a face-to-face (38%) or telephone consultation (32%). The former were more often needed for patients consulting about new conditions (OR 1.56, 95% CI 1.05 to 2.27, p=0.049). The average cost of a practice's response to an e-consultation was L36.28, primarily triage time and resulting face-to-face/telephone consultations needed. CONCLUSIONS: Use of e-consultations is very low, particularly at weekends. Unless this can be improved, any impact on staff workload and patient waiting times is likely to be negligible. It is possible that use of e-consultations increases primary care workload and costs. Online consultation systems could be developed to improve efficiency both for staff and patients. These findings have implications for software developers as well as primary care services and policy-makers who are considering investing in online consultation systems.

PMID- 29167114 TI - Exocrine pancreas glutamate secretion help to sustain enterocyte nutritional needs under protein restriction. AB - Glutamine (Gln) is the most concentrated amino acid in blood and considered conditionally essential. Its requirement is increased during physiological stress, such as malnutrition or illness, despite its production by muscle and other organs. In the malnourished state, Gln has been suggested to have a trophic effect on the exocrine pancreas and small intestine. However, the Gln transport capacity, the functional relationship of these two organs, and the potential role of the Gln-glutamate (Glu) cycle are unknown. We observed that pancreatic acinar cells express lower levels of Glu than Gln transporters. Consistent with this expression pattern, the rate of Glu influx into acinar cells was approximately sixfold lower than that of Gln. During protein restriction, acinar cell glutaminase expression was increased and Gln accumulation was maintained. Moreover, Glu secretion by acinar cells into pancreatic juice and thus into the lumen of the small intestine was maintained. In the intestinal lumen, Glu absorption was preserved and Glu dehydrogenase expression was augmented, potentially providing the substrates for increasing energy production via the TCA cycle. Our findings suggest that one mechanism by which Gln exerts a positive effect on exocrine pancreas and small intestine involves the Gln metabolism in acinar cells and the secretion of Glu into the small intestine lumen. The exocrine pancreas acinar cells not only avidly accumulate Gln but metabolize Gln to generate energy and to synthesize Glu for secretion in the pancreatic juice. Secreted Glu is suggested to play an important role during malnourishment in sustaining small intestinal homeostasis. NEW & NOTEWORTHY Glutamine (Gln) has been suggested to have a trophic effect on exocrine pancreas and small intestine in malnourished states, but the mechanism is unknown. In this study, we suggest that this trophic effect derives from an interorgan relationship between exocrine pancreas and small intestine for Gln-glutamate (Glu) utilization involving the uptake and metabolism of Gln in acinar cells and secretion of Glu into the lumen of the small intestine. PMID- 29167113 TI - Irritable bowel syndrome patients have SCN5A channelopathies that lead to decreased NaV1.5 current and mechanosensitivity. AB - The SCN5A-encoded voltage-gated mechanosensitive Na+ channel NaV1.5 is expressed in human gastrointestinal smooth muscle cells and interstitial cells of Cajal. NaV1.5 contributes to smooth muscle electrical slow waves and mechanical sensitivity. In predominantly Caucasian irritable bowel syndrome (IBS) patient cohorts, 2-3% of patients have SCN5A missense mutations that alter NaV1.5 function and may contribute to IBS pathophysiology. In this study we examined a racially and ethnically diverse cohort of IBS patients for SCN5A missense mutations, compared them with IBS-negative controls, and determined the resulting NaV1.5 voltage-dependent and mechanosensitive properties. All SCN5A exons were sequenced from somatic DNA of 252 Rome III IBS patients with diverse ethnic and racial backgrounds. Missense mutations were introduced into wild-type SCN5A by site-directed mutagenesis and cotransfected with green fluorescent protein into HEK-293 cells. NaV1.5 voltage-dependent and mechanosensitive functions were studied by whole cell electrophysiology with and without shear force. Five of 252 (2.0%) IBS patients had six rare SCN5A mutations that were absent in 377 IBS negative controls. Six of six (100%) IBS-associated NaV1.5 mutations had voltage dependent gating abnormalities [current density reduction (R225W, R433C, R986Q, and F1293S) and altered voltage dependence (R225W, R433C, R986Q, G1037V, and F1293S)], and at least one kinetic parameter was altered in all mutations. Four of six (67%) IBS-associated SCN5A mutations (R225W, R433C, R986Q, and F1293S) resulted in altered NaV1.5 mechanosensitivity. In this racially and ethnically diverse cohort of IBS patients, we show that 2% of IBS patients harbor SCN5A mutations that are absent in IBS-negative controls and result in NaV1.5 channels with abnormal voltage-dependent and mechanosensitive function. NEW & NOTEWORTHY The voltage-gated Na+ channel NaV1.5 contributes to smooth muscle physiology and electrical slow waves. In a racially and ethnically mixed irritable bowel syndrome cohort, 2% had mutations in the NaV1.5 gene SCN5A. These mutations were absent in irritable bowel syndrome-negative controls. Most mutant NaV1.5 channels were loss of function in voltage dependence or mechanosensitivity. PMID- 29167115 TI - Epigenetic modulation of intestinal Na+/H+ exchanger-3 expression. AB - Na+/H+ exchanger-3 (NHE3) is crucial for intestinal Na+ absorption, and its reduction has been implicated in infectious and inflammatory bowel diseases (IBD) associated diarrhea. Epigenetic mechanisms such as DNA methylation are involved in the pathophysiology of IBD. Whether changes in DNA methylation are involved in modulating intestinal NHE3 gene expression is not known. Caco-2 and HuTu 80 cells were used as models of human intestinal epithelial cells. Normal C57/BL6, wild type, or growth arrest and DNA damage-inducible 45b (GADD45b) knockout (KO) mice were used as in vivo models. NHE3 gene DNA methylation levels were assessed by MBDCap (MethyMiner) assays. Results demonstrated that in vitro methylation of NHE3 promoter construct (p-1509/+127) cloned into a cytosine guanine dinucleotide free lucia vector decreased the promoter activity in Caco-2 cells. DNA methyltransferase inhibitor 5-azacytidine (10 MUM, 24 h) caused a significant decrease in DNA methylation of the NHE3 gene and concomitantly increased NHE3 expression in Caco-2 cells. Similarly, 5-azacytidine treatment increased NHE3 mRNA levels in HuTu 80 cells. 5-Azacytidine treatment for 3 wk (10 mg/kg body wt ip, 3 times/wk) also resulted in an increase in NHE3 expression in the mouse ileum and colon. Small-interfering RNA knockdown of GADD45b (protein involved in DNA demethylation) in Caco-2 cells decreased NHE3 mRNA expression. Furthermore, there was a significant decrease in NHE3 mRNA and protein expression in the ileum and colon of GADD45b KO mice. Our findings demonstrate that NHE3 gene expression is regulated by changes in its DNA methylation. NEW & NOTEWORTHY Our studies for the first time demonstrate that Na+/H+ exchanger-3 gene expression is regulated by an epigenetic mechanism involving DNA methylation. PMID- 29167116 TI - Medullary raphe nuclei activate the lumbosacral defecation center through the descending serotonergic pathway to regulate colorectal motility in rats. AB - Colorectal motility is regulated by two defecation centers located in the brain and spinal cord. In previous studies, we have shown that administration of serotonin (5-HT) in the lumbosacral spinal cord causes enhancement of colorectal motility. Because spinal 5-HT is derived from neurons of the medullary raphe nuclei, including the raphe magnus, raphe obscurus, and raphe pallidus, we examined whether stimulation of the medullary raphe nuclei enhances colorectal motility via the lumbosacral defecation center. Colorectal pressure was recorded with a balloon in vivo in anesthetized rats. Electrical stimulation of the medullary raphe nuclei failed to enhance colorectal motility. Because GABAergic neurons can be simultaneously activated by the raphe stimulation and released GABA masks accelerating actions of the raphe nuclei on the lumbosacral defecation center, a GABAA receptor antagonist was preinjected intrathecally to manifest excitatory responses. When spinal GABAA receptors were blocked by the antagonist, electrical stimulation of the medullary raphe nuclei increased colorectal contractions. This effect of the raphe nuclei was inhibited by intrathecal injection of 5-hydroxytryptamine type 2 (5-HT2) and type 3 (5-HT3) receptor antagonists. In addition, injection of a selective 5-HT reuptake inhibitor in the lumbosacral spinal cord augmented the raphe stimulation-induced enhancement of colorectal motility. Transection of the pelvic nerves, but not transection of the colonic nerves, prevented the effect of the raphe nuclei on colorectal motility. These results demonstrate that activation of the medullary raphe nuclei causes augmented contractions of the colorectum via 5-HT2 and 5-HT3 receptors in the lumbosacral defecation center. NEW & NOTEWORTHY We have shown that electrical stimulation of the medullary raphe nuclei causes augmented contractions of the colorectum via pelvic nerves in rats. The effect of the medullary raphe nuclei on colorectal motility is exerted through activation of 5-hydroxytryptamine type 2 and type 3 receptors in the lumbosacral defecation center. The descending serotoninergic raphespinal tract represents new potential therapeutic targets against colorectal dysmotility such as irritable bowel syndrome. PMID- 29167117 TI - Effect of 6 wk of high-intensity one-legged cycling on functional sympatholysis and ATP signaling in patients with heart failure. AB - Breathlessness during daily activities is the primary symptom in patients with heart failure (HF). Poor correlation between the hemodynamic parameters of left ventricular performance and perceived symptoms suggests that other factors, such as skeletal muscle function, play a role in determining exercise capacity. We investigated the effect of 6 wk of high-intensity, one-legged cycling (HIC; 8 * 4 at 90% one-legged cycling max) on 1) the ability to override sympathetic vasoconstriction (arterial infusion of tyramine) during one-legged knee-extensor exercise (KEE), 2) vascular function (arterial infusion of ACh, sodium nitroprusside, tyramine, and ATP), and 3) exercise capacity in HF patients with reduced ejection fraction ( n = 8) compared with healthy individuals ( n = 6). Arterial tyramine infusion lowered leg blood flow and leg vascular conductance at rest and during KEE before the training intervention in both groups ( P < 0.05) but not during KEE after the training intervention. There was no difference between groups. The peak vasodilatory response to ATP was blunted in HF patients ( P < 0.05), whereas there was no difference in ACh- and sodium nitroprusside induced vasodilation between HF patients and healthy individuals. ACh-induced vasodilation increased in HF patients after the training intervention ( P < 0.05). HIC improved aerobic capacity in both groups ( P < 0.05), whereas only HF patients made improvements in the 6-min walking distance ( P < 0.05). These results suggest that exercise hyperemia and functional sympatholysis are not altered in HF patients and that functional sympatholysis is improved with HIC in both HF patients and healthy individuals. Moreover, these results suggest that the peak vasodilatory response to ATP is blunted in HF. NEW & NOTEWORTHY The ability to override sympathetic vasoconstrictor activity (by arterial tyramine infusion) during exercise is not different between heart failure patients and healthy individuals and is improved by high-intensity, one-legged cycling training. The peak vasodilatory response to ATP is reduced in heart failure patients. PMID- 29167118 TI - Exercise facilitates early recognition of cardiac and vascular remodeling in chronic thromboembolic pulmonary hypertension in swine. AB - Chronic thromboembolic pulmonary hypertension (CTEPH) develops in 4% of patients after pulmonary embolism and is accompanied by an impaired exercise tolerance, which is ascribed to the increased right ventricular (RV) afterload in combination with a ventilation/perfusion (V/Q) mismatch in the lungs. The present study aimed to investigate changes in arterial Po2 and hemodynamics in response to graded treadmill exercise during development and progression of CTEPH in a novel swine model. Swine were chronically instrumented and received multiple pulmonary embolisms by 1) microsphere infusion (Spheres) over 5 wk, 2) endothelial dysfunction by administration of the endothelial nitric oxide synthase inhibitor Nomega-nitro-l-arginine methyl ester (L-NAME) for 7 wk, 3) combined pulmonary embolisms and endothelial dysfunction (L-NAME + Spheres), or 4) served as sham-operated controls (sham). After a 9 wk followup, embolization combined with endothelial dysfunction resulted in CTEPH, as evidenced by mean pulmonary artery pressures of 39.5 +/- 5.1 vs. 19.1 +/- 1.5 mmHg (Spheres, P < 0.001), 22.7 +/- 2.0 mmHg (L-NAME, P < 0.001), and 20.1 +/- 1.5 mmHg (sham, P < 0.001), and a decrease in arterial Po2 that was exacerbated during exercise, indicating V/Q mismatch. RV dysfunction was present after 5 wk of embolization, both at rest (trend toward increased RV end-systolic lumen area, P = 0.085, and decreased stroke volume index, P = 0.042) and during exercise (decreased stroke volume index vs. control, P = 0.040). With sustained pulmonary hypertension, RV hypertrophy (Fulton index P = 0.022) improved RV function at rest and during exercise, but this improvement was insufficient in CTEPH swine to result in an exercise-induced increase in cardiac index. In conclusion, embolization in combination with endothelial dysfunction results in CTEPH in swine. Exercise increased RV afterload, exacerbated the V/Q mismatch, and unmasked RV dysfunction. NEW & NOTEWORTHY Here, we present the first double-hit chronic thromboembolic pulmonary hypertension swine model. We show that embolization as well as endothelial dysfunction is required to induce sustained pulmonary hypertension, which is accompanied by altered exercise hemodynamics and an exacerbated ventilation/perfusion mismatch during exercise. PMID- 29167119 TI - Revisiting the physiological effects of exercise training on autonomic regulation and chemoreflex control in heart failure: does ejection fraction matter? AB - Heart failure (HF) is a global public health problem that, independent of its etiology [reduced (HFrEF) or preserved ejection fraction (HFpEF)], is characterized by functional impairments of cardiac function, chemoreflex hypersensitivity, baroreflex sensitivity (BRS) impairment, and abnormal autonomic regulation, all of which contribute to increased morbidity and mortality. Exercise training (ExT) has been identified as a nonpharmacological therapy capable of restoring normal autonomic function and improving survival in patients with HFrEF. Improvements in autonomic function after ExT are correlated with restoration of normal peripheral chemoreflex sensitivity and BRS in HFrEF. To date, few studies have addressed the effects of ExT on chemoreflex control, BRS, and cardiac autonomic control in HFpEF; however, there are some studies that have suggested that ExT has a beneficial effect on cardiac autonomic control. The beneficial effects of ExT on cardiac function and autonomic control in HF may have important implications for functional capacity in addition to their obvious importance to survival. Recent studies have suggested that the peripheral chemoreflex may also play an important role in attenuating exercise intolerance in HFrEF patients. The role of the central/peripheral chemoreflex, if any, in mediating exercise intolerance in HFpEF has not been investigated. The present review focuses on recent studies that address primary pathophysiological mechanisms of HF (HFrEF and HFpEF) and the potential avenues by which ExT exerts its beneficial effects. PMID- 29167120 TI - Acute lysyl oxidase inhibition alters microvascular function in normotensive but not hypertensive men and women. AB - The lysyl oxidase (LOX) family of enzymes regulates collagen cross-linking. LOX is upregulated in hypertension, increasing vascular stiffness. In vivo human research is sparse, as long-term LOX inhibition in animals causes vascular instability. Our aim was to evaluate the effects of LOX inhibition on cutaneous microvascular function to determine whether LOX function was upregulated in hypertensive humans. Four intradermal microdialysis fibers were placed in the forearm of 10 young [age: 24 +/- 1 yr, mean arterial pressure (MAP): 87 +/- 2 mmHg], 10 normotensive (age: 50 +/- 2 yr, MAP: 84 +/- 1 mmHg), and 10 hypertensive (age: 53 +/- 2 yr, MAP: 112 +/- 2 mmHg) subjects. Two sites were perfused with 10 mM beta-aminopropionitrile (BAPN) to inhibit LOX. The remaining two sites were perfused with lactated Ringer solution (control). A norepinephrine dose response (10-12-10-2 M) was performed to examine receptor-mediated vasoconstrictor function. A sodium nitroprusside dose response (10-8-10-1.3 M) was performed to examine vascular smooth muscle vasodilator function. Red blood cell flux was measured via laser-Doppler flowmetry and normalized to cutaneous vascular conductance (flux/MAP). LogEC50 values were calculated to determine changes in vasosensitivity. Skin tissue samples were analyzed for both extracellular matrix-bound and soluble LOX. LOX inhibition augmented vasoconstrictor sensitivity in young (control: -6.0 and BAPN: -7.1, P = 0.03) and normotensive (control: -4.8 and BAPN: -7.0, P = 0.01) but not hypertensive (control: -6.0 and BAPN: -6.1, P = 0.79) men and women. Relative to young subjects, extracellular matrix-bound LOX expression was higher in hypertensive subjects (young: 100 +/- 8 and hypertensive: 162 +/- 8, P = 0.002). These results suggest that upregulated LOX may contribute to the vascular stiffness and microvascular dysfunction characteristic in hypertension. NEW & NOTEWORTHY Matrix bound lysyl oxidase (LOX) and LOX-like 2 expression are upregulated in the microvasculature of hypertensive men and women. Microvascular responsiveness to exogenous stimuli is altered with localized LOX inhibition in healthy men and women but not hypertensive adults. The LOX family differentially affects microvascular function in hypertensive and normotensive men and women. PMID- 29167121 TI - Flow-mediated dilation stimulated by sustained increases in shear stress: a useful tool for assessing endothelial function in humans? AB - Investigations of human conduit artery endothelial function via flow-mediated vasodilation (FMD) have largely been restricted to the reactive hyperemia (RH) technique, wherein a transient increase in shear stress after the release of limb occlusion stimulates upstream conduit artery vasodilation (RH-FMD). FMD can also be assessed in response to sustained increases in shear stress [sustained stimulus (SS)-FMD], most often created with limb heating or exercise. Exercise in particular creates a physiologically relevant stimulus because shear stress increases, and FMD occurs, during typical day-to-day activity. Several studies have identified that various conditions and acute interventions have a disparate impact on RH-FMD versus SS-FMD, sometimes with only the latter demonstrating impairment. Indeed, evidence suggests that transient (RH) and sustained (SS) shear stress stimuli may be transduced via different signaling pathways, and, as such, SS-FMD and RH-FMD appear to offer unique insights regarding endothelial function. The present review describes the techniques used to assess SS-FMD and summarizes the evidence regarding 1) SS-FMD as an index of endothelial function in humans, highlighting comparisons with RH-FMD, and 2) potential differences in shear stress transduction and vasodilator production stimulated by transient versus sustained shear stress stimuli. The evidence suggests that SS-FMD is a useful tool to assess endothelial function and that further research is required to characterize the mechanisms involved and its association with long-term cardiovascular outcomes. NEW & NOTEWORTHY Sustained increases in peripheral conduit artery shear stress, created via distal skin heating or exercise, provide a physiologically relevant stimulus for flow-mediated dilation (FMD). Sustained stimulus FMD and FMD stimulated by transient, reactive hyperemia-induced increases in shear stress provide distinct assessments of conduit artery endothelial function. PMID- 29167122 TI - Burst patterning of hypothalamic paraventricular nucleus-driven sympathetic nerve activity in ANG II-salt hypertension. AB - ANG II-salt hypertension selectively increases splanchnic sympathetic nerve activity (sSNA), but the extent to which this reflects increased respiratory versus cardiac rhythmic bursting is unknown. Here, integrated sSNA was elevated in ANG II-infused rats fed a high-salt (2% NaCl) diet (ANG II-HSD) compared with vehicle-infused rats fed a normal-salt (0.4% NaCl) diet (Veh-NSD; P < 0.01). Increased sSNA was not accompanied by increased inspiratory or expiratory bursting, consistent with no group difference in central inspiratory drive. Consistent with preserved inhibitory baroreflex entrainment of elevated sSNA in ANG II-HSD rats, the time integral ( P < 0.05) and amplitude ( P < 0.01) of cardiac rhythmic sSNA were increased. Consistent with activity of hypothalamic paraventricular nucleus (PVN) neurons supporting basal SNA in ANG II-salt hypertension, inhibition of PVN with the GABA-A receptor agonist muscimol reduced mean arterial pressure (MAP) and integrated sSNA only in the ANG II-HSD group ( P < 0.001). PVN inhibition had no effect on respiratory rhythmic sSNA bursting in either group but reduced cardiac rhythmic sSNA in ANG II-HSD rats only ( P < 0.01). The latter likely reflected reduced inhibitory baroreflex entrainment subsequent to the fall of MAP. Of note is that MAP as well as integrated and rhythmic burst patterns of sSNA were similar in vehicle-infused rats whether they were fed a normal or high-salt diet. Findings indicate that PVN neurons support elevated sSNA in ANG II-HSD rats by driving a tonic component of activity without altering respiratory or cardiac rhythmic bursting. Because sSNA was unchanged in Veh-HSD rats, activation of PVN-driven tonic sSNA appears to require central actions of ANG II. NEW & NOTEWORTHY ANG II-salt hypertension is strongly neurogenic and depends on hypothalamic paraventricular nucleus (PVN)-driven splanchnic sympathetic nerve activity (sSNA). Here, respiratory and cardiac bursts of sSNA were preserved in ANG II-salt rats and unaltered by PVN inhibition, suggesting that PVN neurons drive a tonic component of sSNA rather than modulating dominant patterns of burst discharge. PMID- 29167123 TI - Lower resting and exercise-induced circulating angiogenic progenitors and angiogenic T cells in older men. AB - Aging is associated with a dysfunctional endothelial phenotype as well as reduced angiogenic capabilities. Exercise exerts beneficial effects on the cardiovascular system, possibly by increasing/maintaining the number and/or function of circulating angiogenic cells (CACs), which are known to decline with age. However, the relationship between cardiorespiratory fitness (CRF) and age-related changes in the frequency of CACs, as well as the exercise-induced responsiveness of CACs in older individuals, has not yet been determined. One-hundred seven healthy male volunteers, aged 18-75 yr, participated in study 1. CRF was estimated using a submaximal cycling ergometer test. Circulating endothelial progenitor cells (EPCs), angiogenic T cells (TANG), and their chemokine (C-X-C motif) receptor 4 (CXCR4) cell surface receptor expression were enumerated by flow cytometry using peripheral blood samples obtained under resting conditions before the exercise test. In study 2, 17 healthy men (8 young men, 18-25 yr; 9 older men, 60-75 yr) were recruited, and these participants undertook a 30-min cycling exercise bout at 70% maximal O2 consumption, with CACs enumerated before and immediately after exercise. Age was inversely associated with both CD34+ progenitor cells ( r2 = -0.140, P = 0.000) and TANG ( r2 = -0.176, P = 0.000) cells as well as CXCR4-expressing CACs (CD34+: r2 = -0.167, P = 0.000; EPCs: r2 = -0.098, P = 0.001; TANG: r2 = -0.053, P = 0.015). However, after correcting for age, CRF had no relationship with either CAC subset. In addition, older individuals displayed attenuated exercise-induced increases in CD34+ progenitor cells, TANG, CD4+, TANG, and CD8+CXCR4+ TANG cells. Older men display lower CAC levels, which may contribute to increased risk of cardiovascular disease, and older adults display an impaired exercise-induced responsiveness of these cells. NEW & NOTEWORTHY Older adults display lower circulating progenitor cell and angiogenic T cell counts compared with younger individuals independently of cardiometabolic risk factors and cardiorespiratory fitness. Older adults also display impaired exercise-induced mobilization of these vasculogenic cells. PMID- 29167124 TI - Micro-RNA-1 is decreased by hypoxia and contributes to the development of pulmonary vascular remodeling via regulation of sphingosine kinase 1. AB - Sphingosine kinase 1 (SphK1) upregulation is associated with pathologic pulmonary vascular remodeling in pulmonary arterial hypertension (PAH), but the mechanisms controlling its expression are undefined. In this study, we sought to characterize the regulation of SphK1 expression by micro-RNAs (miRs). In silico analysis of the SphK1 3'-untranslated region identified several putative miR binding sites, with miR-1-3p (miR-1) being the most highly predicted target. Therefore we further investigated the role of miR-1 in modulating SphK1 expression and characterized its effects on the phenotype of pulmonary artery smooth muscle cells (PASMCs) and the development of experimental pulmonary hypertension in vivo. Our results demonstrate that miR-1 is downregulated by hypoxia in PASMCs and can directly inhibit SphK1 expression. Overexpression of miR-1 in human PASMCs inhibits basal and hypoxia-induced proliferation and migration. Human PASMCs isolated from PAH patients exhibit reduced miR-1 expression. We also demonstrate that miR-1 is downregulated in mouse lung tissues during experimental hypoxia-mediated pulmonary hypertension (HPH), consistent with upregulation of SphK1. Furthermore, administration of miR-1 mimics in vivo prevented the development of HPH in mice and attenuated induction of SphK1 in PASMCs. These data reveal the importance of miR-1 in regulating SphK1 expression during hypoxia in PASMCs. A pivotal role is played by miR-1 in pulmonary vascular remodeling, including PASMC proliferation and migration, and its overexpression protects from the development of HPH in vivo. These studies improve our understanding of the molecular mechanisms underlying the pathogenesis of pulmonary hypertension. PMID- 29167125 TI - Mesenchymal stem cells reduce hypoxia-induced apoptosis in alveolar epithelial cells by modulating HIF and ROS hypoxic signaling. AB - Distal lung diseases, such as pulmonary fibrosis or acute lung injury, are commonly associated with local alveolar hypoxia that may be deleterious through the stimulation of alveolar epithelial cell (AEC) apoptosis. In various murine models of alveolar injury, administration of allogenic human mesenchymal stem cells (hMSCs) exerts an overall protective paracrine effect, limiting lung inflammation and fibrosis. However, the precise mechanisms on lung cells themselves remain poorly understood. Here, we investigated whether hMSC conditioned medium (hMSC-CM) would protect AECs from hypoxia-induced apoptosis and explored the mechanisms involved in this cytoprotective effect. Exposure of rat primary AECs to hypoxia (1.5% O2 for 24 h) resulted in hypoxia-inducible factor (HIF)-1alpha protein stabilization, partly dependent on reactive oxygen species (ROS) accumulation, and in a twofold increase in AEC apoptosis that was prevented by the HIF inhibitor 3-(5'-hydroxymethyl-2'-furyl)-1-benzyl-indazole and the antioxidant drug N-acetyl cysteine. Incubation of AECs with hMSC-CM significantly reduced hypoxia-induced apoptosis. hMSC-CM decreased HIF-1alpha protein expression, as well as ROS accumulation through an increase in antioxidant enzyme activities. Expression of Bnip3 and CHOP, two proapoptotic targets of HIF-1alpha and ROS pathways, respectively, was suppressed by hMSC-CM, while Bcl-2 expression was restored. The paracrine protective effect of hMSC was partly dependent on keratinocyte growth factor and hepatocyte growth factor secretion, preventing ROS and HIF-1alpha accumulation. PMID- 29167127 TI - HCAHPS survey to measure pain communication, not management. PMID- 29167126 TI - Chronic lung injury and impaired pulmonary function in a mouse model of acid ceramidase deficiency. AB - Farber disease (FD) is a debilitating lysosomal storage disorder (LSD) caused by a deficiency of acid ceramidase (ACDase) activity due to mutations in the gene ASAH1. Patients with ACDase deficiency may develop a spectrum of clinical phenotypes. Severe cases of FD are frequently associated with neurological involvement, failure to thrive, and respiratory complications. Mice homozygous ( Asah1P361R/P361R) for an orthologous patient mutation in Asah1 recapitulate human FD. In this study, we show significant impairment in lung function, including low compliance and increased airway resistance in a mouse model of ACDase deficiency. Impaired lung mechanics in Farber mice resulted in decreased blood oxygenation and increased red blood cell production. Inflammatory cells were recruited to both perivascular and peribronchial areas of the lung. We observed large vacuolated foamy histiocytes that were full of storage material. An increase in vascular permeability led to protein leakage, edema, and impacted surfactant homeostasis in the lungs of Asah1P361R/P361R mice. Bronchial alveolar lavage fluid (BALF) extraction and analysis revealed accumulation of a highly turbid lipoprotein-like substance that was composed in part of surfactants, phospholipids, and ceramides. The phospholipid composition of BALF from Asah1P361R/P361R mice was severely altered, with an increase in both phosphatidylethanolamine (PE) and sphingomyelin (SM). Ceramides were also found at significantly higher levels in both BALF and lung tissue from Asah1P361R/P361R mice when compared with levels from wild-type animals. We demonstrate that a deficiency in ACDase leads to sphingolipid and phospholipid imbalance, chronic lung injury caused by significant inflammation, and increased vascular permeability, leading to impaired lung function.

AB - PURPOSE: Promising developments in the search for effective pharmacotherapies for autosomal-dominant polycystic kidney disease (ADPKD) are reviewed. SUMMARY: The formation and development of cysts characteristic of ADPKD result in inexorable renal and extrarenal manifestations that give rise to more rapid disease progression and more widespread complications than are seen with other forms of chronic kidney disease. To date, no agent has gained Food and Drug Administration marketing approval for use in patients with ADPKD, complicating efforts to meet the medical needs of this population. Although definitive ultrasonographic diagnostic strategies are available, molecular screening approaches lack sufficient evidence and patient outcomes data to support broad clinical application. Recently completed and ongoing clinical trials point to a number of encouraging platforms for evidence-based ADPKD management. Tolvaptan therapy significantly improved cyst burden and slowed disease progression among patients with early-stage ADPKD in a large-scale trial, while somatostatin therapies may also be useful in halting disease progression and managing comorbid polycystic liver disease. Stem cell research and nanomedicine might represent novel approaches to gaining comprehensive insights on ADPKD and, ultimately, to targeting the disease's origins, thereby making restoration of kidney function possible. CONCLUSION: A number of pharmacotherapy approaches to ADPKD management show promise but are unlikely to be curative, fueling interest among researchers in finding new applications for nanomedicine and stem cell technologies that can slow ADPKD progression and better control complications of the disease. PMID- 29167139 TI - Development and validation of a complexity score to rank hospitalized patients at risk for preventable adverse drug events. AB - PURPOSE: The development of risk models for 16 preventable adverse drug events (pADEs) and their aggregation into the final complexity score (C-score) are described. METHODS: Using data from 2 tertiary care facilities, logistic regression models were constructed for the first 5 hospital days that admissions were at risk for each of 16 pADEs. The best model for each pADE was validated in 100 bootstrap samples. The C-score was then aggregated and predicted individual pADE risk as the probability to develop at least 1 pADE. Using the 100 bootstrap samples for each pADE, 100 C-scores for validation were generated. RESULTS: We utilized electronic health records (EHR) data from 65,518 admissions to UF Health Shands and 18,269 admissions to UF Health Jacksonville to develop risk models for 16 pADEs. Most models had very strong discriminant validity (C-statistic > 0.8), with the highest predicted decile representing about half of manifest pADEs. Among admissions in the highest C-score decile, about two thirds experienced at least 1 pADE (C-statistic, 0.838; 95% confidence interval, 0.838-0.839). C-score precision, defined as the percentage of patients consistently (i.e., at least 95 of 100 samples) ranked in the 90th percentile, was 80-84%. CONCLUSION: The C score was developed and validated for the identification of hospitalized patients at highest risk for pADEs. Aggregation of individual prediction models into a single score reduced its predictive power for most pADEs, compared with the individual risk models, but concentrated in the highest C-score decile a patient group more than two thirds of whom experienced at least 1 pADE. PMID- 29167140 TI - Needs assessment for developing a program to help train advanced-practice pharmacists for research. AB - PURPOSE: Results of a needs assessment to determine priority topics and preferred formats for research training in pharmacy residency programs are reported. SUMMARY: For pharmacists seeking advanced-practice positions in academia, the ability to conduct practice-based research is expected. Pharmacy residency programs are a primary recruitment source for these positions, but research training varies by residency site and available expertise. To help define the optimal content and format of resident research training, ASHP and the ASHP Research and Education Foundation conducted a needs assessment targeting postgraduate year 1 (PGY1) pharmacy residency directors (RPDs). The response rate was 36.5% (271 of 743 invitees); the information obtained was used to guide development of a Web-based training series. Only 12% of the RPDs who participated in the survey indicated that currently available research training resources within their residency programs were sufficient. Sixty-seven percent of surveyed RPDs agreed that a Web-based training program would be a useful resource, and 81% agreed that the target audience should be pharmacy residents. Training topics of greatest interest to RPDs included (1) components of a resident research plan, (2) identifying research questions, (3) study design and sample selection, (4) project management, (5) data acquisition, cleaning, management, and analysis, and (6) presenting and publishing project results. CONCLUSION: This needs assessment clearly identified opportunities for improving the infrastructure and content of PGY1 residency research training. At a minimum, training programs should focus on practice-based research concepts using readily accessible health-system data systems and provide universal accessibility and sufficient flexibility to allow residency programs to integrate the training in a manner that works best for the program. PMID- 29167141 TI - Impact of automatic infectious diseases consultation on the management of fungemia at a large academic medical center. AB - PURPOSE: The impact of automatic infectious diseases (ID) consultation for inpatients with fungemia at a large academic medical center was studied. METHODS: In this single-center, retrospective study, the time to appropriate antifungal therapy before and after implementing a policy requiring automatic ID consultation for the management of fungemia for all patients with an inpatient positive blood culture for fungus was examined. The rates of ID consultation; the likelihood of receiving appropriate antifungal therapy; central venous catheter (CVC) removal rates; performance of ophthalmologic examinations; infection related length of stay (LOS); rates of all-cause inhospital mortality, death, or transfer to an intensive care unit within 7 days of first culture; and inpatient cost of antifungals were also evaluated. RESULTS: A total of 173 unique episodes (94 and 79 in the control and intervention groups, respectively) were included. Candida species were the most frequently cultured organisms, isolated from over 90% of patients in both groups. No differences were observed between the control and intervention groups in time to appropriate therapy, infection-related LOS, or time to CVC removal. However, patients in the intervention group were more likely than those in the control group to receive appropriate antifungal therapy (p = 0.0392), undergo ophthalmologic examination (p = 0.003), have their CVC removed (p = 0.0038), and receive ID consultation (p = 0.0123). Inpatient antifungal costs were significantly higher in the intervention group (p = 0.0177). CONCLUSION: While automatic ID consultation for inpatients with fungemia did not affect the time to administration of appropriate therapy, improvement was observed for several process indicators, including rates of appropriate antifungal therapy selection, time to removal of CVCs, and performance of ophthalmologic examinations.

AB - PURPOSE: An innovative certificate program aimed at expanding the rural pharmacy workforce, increasing the number of pharmacists with expertise in rural practice, and improving healthcare outcomes in rural North Carolina is described. SUMMARY: Predicted shortages of primary care physicians and closures of critical access hospitals are expected to worsen existing health disparities. Experiential education in schools and colleges of pharmacy primarily takes place in academic medical centers and, unlike experiential education in medical schools, rarely emphasizes the provision of patient care in rural U.S. communities, where chronic diseases are prevalent and many residents struggle with poverty and poor access to healthcare. To help address these issues, UNC Eshelman School of Pharmacy developed the 3-year Rural Pharmacy Health Certificate program. The program curriculum includes 4 seminar courses, interprofessional education and interaction with medical students, embedding of each pharmacy student into a specific rural community for the duration of training, longitudinal ambulatory care practice experiences, community engagement initiatives, leadership training, development and implementation of a population health project, and 5 pharmacy practice experiences in rural settings. CONCLUSION: The Rural Pharmacy Health Certificate program at UNC Eshelman School of Pharmacy seeks to transform rural pharmacy practice by creating a pipeline of rural pharmacy leaders and teaching a unique skillset that will be beneficial to healthcare systems, communities, and patients.

PMID- 29167144 TI - Efficiency analysis of a barcode-enabled and integrated medication-tracking system. AB - PURPOSE: Operational efficiency improvements for pharmacy workflow processes were evaluated using a barcode-enabled and integrated medication-tracking system for medications dispensed from the pharmacy to the emergency department (ED). METHODS: The preimplementation study period (Period 1) was defined as November 17 December 16, 2015; system implementation and training, were defined as December 17, 2015-January 18, 2016; and postimplementation (Period 2) was defined as January 19-February 17, 2016. Periods 1 and 2 were compared to (1) quantify the number and type of phone calls received related to medication inquiries, (2) evaluate the percentage of redispensed doses per total dispensed doses, and (3) assess the rate of medication administration record (MAR) messages received per total dispensed doses. RESULTS: A reduction in the total number of phone calls by 77% was observed (from 125 to 29 calls). A 0.7% difference was detected for re dispensed doses as well as MAR messages (0.009% difference in rate) between the 2 study periods. This difference was observed despite an increase in the total amount of dispensed doses that occurred for both redispensed doses (936) and MAR messages (920) during Period 2. CONCLUSION: A barcode-enabled and integrated medication-tracking system was successfully implemented into the medication distribution process in the ED. The process change increased operational pharmacy efficiencies by decreasing medication status phone calls, redispensed doses, and MAR messages. PMID- 29167145 TI - Impact of pharmacist intervention on influenza vaccine assessment and documentation in hospitalized psychiatric patients. AB - PURPOSE: Results of an initiative to improve assessment and documentation of the influenza vaccination status of adult psychiatric inpatients are reported. METHODS: A prospective quality-improvement study was conducted at a large, tertiary care academic medical center with the aim of improving compliance with the Influenza Immunization (IMM-2) quality measure, which was added to the Inpatient Psychiatric Facility Quality Reporting (IPFQR) program in 2015 and requires assessment and documentation of influenza vaccination status in specified groups of psychiatric inpatients. The primary objective was to improve the IMM-2 IPFQR compliance rate to 100% during the 2015-16 influenza season from a rate of 55% during the 2014-15 influenza season through pharmacist interventions; secondary objectives included analysis of types of pharmacist interventions, rates of influenza vaccination status assessment and ordering, and rates of vaccine refusal by psychiatric disease state. RESULTS: With pharmacist interventions, the IMM-2 IPFQR compliance rate was increased to 99% during the 2015-16 influenza season. Of the 1,413 patients included in the study population, 45% (n = 646) were targeted for pharmacist intervention. Influenza vaccine was ordered for 61% of the study population (n = 867 patients), with an overall refusal rate of 74% (n = 642). Differences in refusal rates by psychiatric diagnosis were not significant. CONCLUSION: Pharmacist-conducted education of nurses and interventions to ensure completion of influenza vaccine assessments and documentation led to an improved IMM-2 IPFQR compliance rate at the study site. PMID- 29167146 TI - Impact of educational intervention on management of periprocedural anticoagulation. AB - PURPOSE: The effect of education regarding new evidence in periprocedural anticoagulation, with a focus on reducing use in patients at only moderate thromboembolic risk, is presented. METHODS: A retrospective cohort analysis and quasiexperimental design were used. The initial review identified the current state of practice regarding bridging anticoagulation. Education was then provided to primary care providers and pharmacists on recent evidence. A subsequent review was completed to assess the impact of this education on clinical decision-making. Inclusion criteria were adults taking warfarin for an indication of mechanical heart valve, atrial fibrillation (AF), or history of venous thromboembolism (VTE) and required interruption of warfarin therapy to undergo a planned procedure. Patients were excluded if their anticoagulation was managed outside of the Minneapolis Veterans Affairs Anticoagulation Clinic. RESULTS: The overall rate of bridging decreased from 38.8% to 24.8% (14% decrease; 95% confidence interval [CI], 2-26%; p = 0.028) confidence interval [CI], 0.02-0.26; p = 0.026) after educational intervention. This decrease occurred in the moderate thromboembolic risk group, in which the bridging rate decreased from 63.8% to 30.2% (33.6% decrease; 95% CI, 14-53%; p = 0.001). Bleeding complications occurred more frequently in patients who received bridging. There were no thromboembolic complications. CONCLUSION: The majority of patients at moderate thromboembolic risk were previously receiving bridging until new evidence was released indicating that the risks may outweigh any benefits. The provision of education to primary care physicians and pharmacy staff regarding this new evidence in the area of periprocedural anticoagulation management significantly reduced the amount of bridging used for patients on warfarin for AF or a history of VTE who were at moderate thromboembolic risk. PMID- 29167147 TI - Medication errors resulting in harm: Using chargemaster data to determine association with cost of hospitalization and length of stay. AB - PURPOSE: Results of an analysis of the economic impact of adverse drug events (ADEs) resulting in patient harm on hospitalization costs and length of stay (LOS) are reported. METHODS: In a retrospective single-site study, medication errors among patients admitted to an academic medical center during the period April 2014-May 2015 were identified using voluntary event reporting system data and diagnosis codes. Hospitalization cases involving documented ADEs resulting in harm, as defined on a widely used medication error classification index, were matched with control cases by admission period, diagnosis-related group, and patient age and sex. Total hospitalization costs and LOS in the study groups were analyzed using an independent 2-sample Mann-Whitney U test. RESULTS: Among 416 hospitalization cases evaluated for inclusion in the study, 242 were matched with 3,279 control cases for analysis. The primary drug classes implicated in the evaluated medication errors included chemotherapy agents (38%), corticosteroids (14%), and opioids (11%). Total hospitalization costs differed significantly (p = 0.044) between patients who experienced ADEs resulting in harm (median, $19,444; interquartile range [IQR], $13,481-$40,580) and those who did not (median, $17,173; IQR, $12,500-$27,125); the former group also had a significantly (p = 0.005) longer median LOS. CONCLUSION: Chargemaster data for an academic medical center revealed that the median total hospitalization cost and LOS were significantly greater for hospitalizations during which a harm-causing medication error was recorded versus hospitalizations during which harm-causing medication errors were not recorded. PMID- 29167148 TI - Neonatal cardiomyocyte hypertrophy induced by endothelin-1 is blocked by estradiol acting on GPER. AB - Estradiol (E2) prevents cardiac hypertrophy, and these protective actions are mediated by estrogen receptor (ER)alpha and ERbeta. The G protein-coupled estrogen receptor (GPER) mediates many estrogenic effects, and its activation in the heart has been observed in ischemia and reperfusion injury or hypertension models; however, the underlying mechanisms need to be fully elucidated. Herein, we investigated whether the protective effect of E2 against cardiomyocyte hypertrophy induced by endothelin-1 (ET-1) is mediated by GPER and the signaling pathways involved. Isolated neonatal female rat cardiomyocytes were treated with ET-1 (100 nmol/l) for 48 h in the presence or absence of E2 (10 nmol/l) or GPER agonist G-1 (10 nmol/l) and GPER antagonist G-15 (10 nmol/l). ET-1 increased the surface area of cardiomyocytes, and this was associated with increased expression of atrial and brain natriuretic peptides. Additionally, ET-1 increased the phosphorylation of extracellular signal-related protein kinases-1/2 (ERK1/2). Notably, E2 or G-1 abolished the hypertrophic actions of ET-1, and that was reversed by G-15. Likewise, E2 reversed the ET-1-mediated increase of ERK1/2 phosphorylation as well as the decrease of phosphorylated Akt and its upstream activator 3-phosphoinositide-dependent protein kinase-1 (PDK1). These effects were inhibited by G-15, indicating that they are GPER dependent. Confirming the participation of GPER, siRNA silencing of GPER inhibited the antihypertrophic effect of E2. In conclusion, E2 plays a key role in antagonizing ET-1-induced hypertrophy in cultured neonatal cardiomyocytes through GPER signaling by a mechanism involving activation of the PDK1 pathway, which would prevent the increase of ERK1/2 activity and consequently the development of hypertrophy. PMID- 29167149 TI - Three-dimensional imaging reveals endo(sarco)plasmic reticulum-containing invaginations within the nucleoplasm of muscle. AB - The mammalian nucleus has invaginations from the cytoplasm, termed nucleoplasmic reticulum (NR). With increased resolution of cellular imaging, progress has been made in understanding the formation and function of NR. In fact, nucleoplasmic Ca2+ homeostasis has been implicated in the regulation of gene expression, DNA repair, and cell death. However, the majority of studies focus on cross-sectional or single-plane analyses of NR invaginations, providing an incomplete assessment of its distribution and content. Here, we provided advanced imaging and three dimensional reconstructive analyses characterizing the molecular constituents of nuclear invaginations in the nucleoplasm in HEK293 cells, murine C2C12 muscle cells, and cardiac myocytes. We demonstrated the presence of critical Ca2+ regulatory channels, including sarco(endo)plasmic reticulum Ca2+-ATPase 2a (SERCA2a), stromal interaction molecule 1 (STIM1), and Ca2+ release-activated Ca2+ channel protein 1 (ORAI1), in the nucleoplasm in isolated primary mouse cardiomyocytes. We have shown for the first time the presence of STIM1 and ORAI1 in the nucleoplasm, suggesting the presence of store-operated calcium entry (SOCE) mechanism in nucleoplasmic Ca2+ regulation. These results show that nucleoplasmic invaginations contain continuous endoplasmic reticulum components, mitochondria, and intact nuclear membranes, highlighting the extremely detailed and complex nature of this organellar structure. PMID- 29167150 TI - The dawn of succinylation: a posttranslational modification. AB - Posttranslational modifications affect almost all proteins and are critical to a well-functioning and diverse proteome; however, many modifications remain relatively unknown and unstudied. This paper will give a perspective on the rapidly developing, novel posttranslational modification called succinylation. This modification may be implicated in numerous diseases, such as hepatic, cardiac, and pulmonary diseases. Although the influences of this modification still remain poorly understood, we are confident that further research into succinylation will provide an enhanced understanding of the complex machinery within the mitochondria, as well as the imposing consequences associated with its dysfunction. PMID- 29167151 TI - Substituted-cysteine accessibility and cross-linking identify an exofacial cleft in the 7th and 8th helices of the proton-coupled folate transporter (SLC46A1). AB - The proton-coupled folate transporter (PCFT-SLC46A1) is required for folate transport across the apical membrane of the small intestine and across the choroid plexus. This study focuses on the structure/function of the 7th transmembrane domain (TMD), and its relationship to the 8th TMD as assessed by the substituted cysteine accessibility method (SCAM) and dicysteine cross linking. Nine exofacial residues (I278C; H281C-L288C) of 23 residues in the 7th TMD were accessible to 2-((biotinoyl)amino)ethyl methanethiosulfonate (MTSEA biotin). Pemetrexed, a high-affinity substrate for PCFT, decreased or abolished biotinylation of seven of these residues consistent with their location in or near the folate binding pocket. Homology models of PCFT based on Glut5 fructose transporter structures in both inward- and outward- open conformations were constructed and predicted that two pairs of residues (T289-I304C and Q285-Q311C) from the 7th and 8th TMDs should be in sufficiently close proximity to form a disulfide bond when substituted with cysteines. The single Cys-substituted mutants were accessible to MTSEA-biotin and functional with and without pretreatment with dithiotreitol. However, the double mutants were either not accessible at all, or accessibility was markedly reduced and function markedly impaired. This occurred spontaneously without inclusion of an oxidizing agent. Dithiotreitol restored accessibility and function consistent with disulfide bond disruption. The data establish the proximity of exofacial regions of the 7th and 8th TMDs and their role in defining the aqueous translocation pathway and suggest that these helices may be a component of an exofacial cleft through which substrates enter the protein binding pocket in its outward-open conformation. PMID- 29167152 TI - RAB27B requirement for stretch-induced exocytosis in bladder umbrella cells. AB - Umbrella cells, which must maintain a tight barrier, modulate their apical surface area during bladder filling by exocytosis of an abundant, subapical pool of discoidal- and/or fusiform-shaped vesicles (DFVs). Despite the importance of this trafficking event for bladder function, the pathways that promote DFV exocytosis remain to be identified. We previously showed that DFV exocytosis depends in part on a RAB11A-RAB8A-MYO5B network, but RAB27B is also reported to be associated with DFVs, and knockout mice lacking RAB27B have fewer DFVs. However, the RAB27B requirements for DFV exocytosis and the relationship between RAB27B and the other umbrella cell-expressed RABs remains unclear. Using a whole bladder preparation, we observed that filling-induced exocytosis of human growth hormone-loaded DFVs was significantly inhibited when RAB27B expression was downregulated using shRNA. RAB27A was also expressed in rat urothelium; however, RAB27A-specific shRNAs did not inhibit exocytosis, and the combination of RAB27A and RAB27B shRNAs did not significantly affect DFV exocytosis more than treatment with RAB27B shRNA alone. RAB27B and RAB11A showed a small degree of overlap when quantified using Squassh segmentation software, and expression of dominant-active or dominant-negative mutants of RAB11A or RAB8A, or expression of a RAB11A specific shRNA, had no significant effect on the size, number, or intensity of RAB27B-positive DFVs. Likewise, treatment with RAB27B-specific shRNA had no effect on RAB11A-positive DFV parameters. We conclude that RAB27B, but not RAB27A, regulates DFV exocytosis in bladder umbrella cells in a manner that may be parallel to the previously described RAB11A-RAB8A-MYO5B pathway.

PMID- 29167154 TI - Implementation of the EULAR cardiovascular risk management guideline in patients with rheumatoid arthritis: results of a successful collaboration between primary and secondary care. AB - The updated European League Against Rheumatism (EULAR) guideline recommends cardiovascular disease (CVD) risk assessment at least once every 5 years in all patients with rheumatoid arthritis (RA). This viewpoint starts with a literature overview of studies that investigated the level of CVD risk factor (CVD-RF) screening in patients with RA in general practices or in outpatient clinics. These studies indicate that CVD-RF screening in patients with RA is marginally applied in clinical practice, in primary as well as secondary care. Therefore, the second part of this viewpoint describes an example of the successful implementation of the EULAR cardiovascular disease risk management (CVRM) guideline in patients with RA in a region in the south of the Netherlands where rheumatologists and general practitioners (GPs) closely collaborate to manage the cardiovascular risk of patients with RA. The different components of this collaboration and the responsibilities of respectively primary and secondary care professionals are described. Within this collaboration, lipid profile was used as an indicator to assess whether CVD-RF screening was performed in the previous 5 years. In 72% (n=454) of the 628 patients with RA, a lipid profile was determined in the previous 5 years. As part of routine quality control, a reminder was sent to the GP in case a patient with RA was not screened. After sending the reminder letter, in 88% of all patients with RA, CVD risk assessment was performed. This collaboration can be seen as good practice to provide care in line with the EULAR guideline.

AB - PREMISE OF THE STUDY: Mediterranean-type climate ecosystems experience significant variability in precipitation within and across years and may be characterized by periods of extreme drought followed by a brief, high-intensity precipitation pulse. Rapid root growth could be a key factor in effective utilization of precipitation pulses, leading to higher rates of seedling establishment. Changes in root growth rate are rarely studied, however, and patterns in seedling root traits are not well explored. We investigated the influence of an extreme postdrought precipitation event on seedlings that occur in southern California coastal sage scrub. METHODS: We measured root elongation rate, root tip appearance rate, new leaf appearance rate, and canopy growth rate on 18 mediterranean species from three growth forms. KEY RESULTS: Root elongation rate responded more strongly to the precipitation pulse than did root tip appearance rate and either metric of aboveground growth. The majority of species exhibited a significant change in root growth rate within 1 week of the pulse. Responses varied in rapidity and magnitude across species, however, and were not generally predictable based on growth form. CONCLUSIONS: While the majority of species exhibited shifts in belowground growth following the pulse, the direction and magnitude of these morphological responses were highly variable within growth form. Understanding the implications of these different response strategies for plant fitness is a crucial next step to forecasting community dynamics within ecosystems characterized by resource pulses. PMID- 29167157 TI - Bipolar distributions in vascular plants: A review. AB - Bipolar disjunct distributions are a fascinating biogeographic pattern exhibited by about 30 vascular plants, whose populations reach very high latitudes in the northern and southern hemispheres. In this review, we first propose a new framework for the definition of bipolar disjunctions and then reformulate a list of guiding principles to consider how to study bipolar species. Vicariance and convergent evolution hypotheses have been argued to explain the origin of this fragmented distribution pattern, but we show here that they can be rejected for all bipolar species, except for Carex microglochin Instead, human introduction and dispersal (either direct or by mountain-hopping)-facilitated by standard and nonstandard vectors-are the most likely explanations for the origin of bipolar plant disjunctions. Successful establishment after dispersal is key for colonization of the disjunct areas and appear to be related to both intrinsic (e.g., self-compatibility) and extrinsic (mutualistic and antagonistic interactions) characteristics. Most studies on plant bipolar disjunctions have been conducted in Carex (Cyperaceae), the genus of vascular plants with the largest number of bipolar species. We found a predominant north-to-south direction of dispersal, with an estimated time of diversification in agreement with major cooling events during the Pliocene and Pleistocene. Bipolar Carex species do not seem to depend on specialized traits for long-distance dispersal and could have dispersed through one or multiple stochastic events, with birds as the most likely dispersal vector. PMID- 29167158 TI - Observations on bipolar disjunctions of moonwort ferns (Botrychium, Ophioglossaceae). AB - Peter Raven, in 1963, included two fern taxa of the genus Botrychium in his list of plant species exhibiting American amphitropical bipolar disjunctions. He attributed the southern hemisphere occurrences to post-Pleistocene long-distance dispersal from counterparts in the northern hemisphere, probably assisted by annual bird migrations between the disjunct areas. Using genetic evidence gathered through worldwide analyses of phylogenetic relationship in Botrychium, we now review and reconsider Raven's conclusions. Genetic similarities indicate that South American Botrychium dusenii is an allotetraploid taxon closely related to B. spathulatum, a North American endemic, and that B. lunaria in New Zealand possesses a genotype identical to that of a taxon in North America derived through introgressive hybridization between B. lunaria and an endemic North American species, B. neolunaria Both North American counterparts exhibit Raven's characteristics of bipolar disjuncts in their occurrence in mountain and coastal meadows, copious production of small propagules (spores in Botrychium), occurrence in habitats frequented by transpolar bird migrants, and ability to found new colonies through inbreeding. We discuss these characteristics in Botrychium and relative to other ferns and suggest further studies on Botrychium and related taxa to address questions of time, number, and mode of bipolar dispersals. PMID- 29167159 TI - Niche shifts after long-distance dispersal events in bipolar sedges (Carex, Cyperaceae). AB - PREMISE OF THE STUDY: Bipolar species represent the greatest biogeographical disjunction on Earth, raising many questions about the colonization and adaptive processes behind such striking distribution. We investigated climatic niche differences of five Carex bipolar species in North and South America to assess niche shifts between these two regions. Moreover, we assessed potential distribution changes with future climate change. METHODS: We used 1202 presence data points from herbarium specimens and 19 bioclimatic variables to assess climatic niche differences and potential distributions among the five species using ordination methods and Maxent. KEY RESULTS: The niche overlap analyses showed low levels of niche filling and high climatic niche expansion between North and South America. Carex macloviana and C. maritima showed the greatest niche expansion (60% and 96%, respectively), followed by C. magellanica (45%) and C. microglochin (39%). Only C. canescens did not colonize new environments (niche expansion = 0.2%). In contrast, all species but C. magellanica had niche filling that was <40%; hence, they are absent in the south from many environments they inhabit in North America. Climate change will push all species toward higher latitudes and elevation, reducing the availability of suitable environments. CONCLUSIONS: The colonization of South America seems to have involved frequent climatic niche shifts. Most species have colonized new environments from those occupied in the North. Observed niche shifts appear congruent with time since colonization and with current genetic structure within species. In these cold dwelling species, climate change will most likely decrease their suitable environments in the future. PMID- 29167160 TI - Persistent pollinators and the evolution of complete selfing. PMID- 29167161 TI - Inferring long-distance dispersal modes in American amphitropically disjunct species through adaptive dispersal structures. AB - PREMISE OF THE STUDY: A repeated pattern of American amphitropical disjunct species or sister species distributed on either side of the equator has long fascinated botanists, but the modes of these disjunctions remain untested. We evaluated diaspore morphology to generate hypotheses on probable dispersal mechanisms. METHODS: The sizes and structures of diaspores, habit, habitat, distribution, and dispersal units were collected for 108 species from literature searches and herbarium specimens. Variation was evaluated with summary statistics, chi2 tests with Monte Carlo simulations, ANOVAs, and the nonparametric Mann-Whitney test. KEY RESULTS: Seeds were the dispersing diaspore in 38.0% of the species, 45.4 were dispersed as fruits, and the remaining were dispersed as infructescences or spores. Diaspores were epizoochorous (52.8%), anemochorous (20.4%), achorous (15.7%), endozoochorous (8.3%), and hydrochorous (2.8%). Epizoochory was significantly greater than expected. Zoochory occurred more frequently than expected when considering achorous diaspores as animal dispersed. Most species were associated with wetland, woodland, and grassland habitats. An ANOVA revealed that diaspores associated with hydrochory were larger and anemochory was smaller; all other syndromes were not significantly different. CONCLUSIONS: Botanists have long-held the assumption that bird migrations are responsible for amphitropical disjunctions. Our results support this hypothesis, with the majority of these events occurring by external attachment of small fruits. However, our results also indicate that anemochory might play a greater role in producing amphitropical distributions than previously thought and at a greater rate than endozoochory or hydrochory. PMID- 29167162 TI - Naturally fragmented and isolated distribution in subtropical grassland patches affects genetic diversity and structure at different spatial scales: The case of Tibouchina hatschbachii, an endemic shrub from Brazil. AB - PREMISE OF THE STUDY: The genetic structure of organisms results from the interactions between life history traits and the ecological and demographic characteristics of the landscape that shape the intra- and interpopulation genetic variation in space and time. In this study, we used a species restricted to islands of grassland vegetation in southern Brazil to investigate the effects of its naturally fragmented distribution on diversity and genetic structure patterns. METHODS: Diversity and intra- and interpopulational genetic structure were analyzed using polymorphisms of eight nuclear microsatellite markers in 205 individuals of T. hatschbachii and Bayesian and multivariate methods. KEY RESULTS: At the intrapopulation level, populations presented low genetic diversity and strong spatial genetic structure, indicating a greater spatial autocorrelation until ~50-500 m. At the interpopulation level, genetic variation partitioned into two geographically structured genetic clusters. Gene flow through pollen was more efficient than gene flow by seeds. CONCLUSIONS: Genetic structure was influenced locally by seed and pollen dispersal dynamics and regionally by fragmentation of the grassland landscape. This study highlights the importance of geological barriers, and potentially a role for genetic drift, in influencing diversification of species in subtropical grasslands of southern Brazil.

PMID- 29167164 TI - NRF2 prevents hypertension, increased ADMA, microvascular oxidative stress, and dysfunction in mice with two weeks of ANG II infusion. AB - Nuclear factor erythyroid factor 2 (Nrf2) transcribes genes in cultured endothelial cells that reduce reactive oxygen species (ROS) and generate nitric oxide (NO) or metabolize asymmetric dimethylarginine (ADMA), which inhibits NO synthase (NOS). Therefore, we undertook a functional study to test the hypothesis that activation of Nrf2 by tert-butylhydroquinone (tBHQ) preserves microvascular endothelial function during oxidative stress. Wild-type CB57BL/6 (wt), Nrf2 wt (+/+), or knockout (-/-) mice received vehicle (Veh) or tBHQ (0.1%; activator of Nrf2) during 14-day infusions of ANG II (to induce oxidative stress) or sham. MAP was recorded by telemetry. Mesenteric resistance arterioles were studied on isometric myographs and vascular NO and ROS by fluorescence microscopy. ANG II increased the mean arterial pressure (112 +/- 5 vs. 145 +/- 5 mmHg; P < 0.01) and excretion of 8-isoprostane F2alpha (2.8 +/- 0.3 vs. 3.8 +/- 0.3 ng/mg creatinine; P < 0.05) at 12-14 days. However, 12 days of ANG II reduced endothelium-derived relaxation (27 +/- 5 vs. 17 +/- 3%; P < 0.01) and NO (0.38 +/- 0.07 vs. 0.18 +/- 0.03 units; P < 0.01) but increased microvascular remodeling, endothelium-derived contractions (7.5 +/- 0.5 vs. 13.0 +/- 1.7%; P < 0.01), superoxide (0.09 +/- 0.03 vs. 0.29 +/- 0.08 units; P < 0.05), and contractions to U-46,619 (87 +/- 6 vs. 118 +/- 3%; P < 0.05), and endothelin-1(89 +/- 4 vs. 123 +/- 12%; P < 0.05). tBHQ prevented all of these effects of ANG II at 12-14 days in Nrf2+/+ mice but not in Nrf2-/- mice. In conclusion, tBHQ activates Nrf2 to prevent microvascular endothelial dysfunction, remodeling, and contractility, and moderate ADMA and hypertension at 12-14 days of ANG II infusion, thereby preserving endothelial function and preventing hypertension. PMID- 29167165 TI - Long-term high-altitude hypoxia influences pulmonary arterial L-type calcium channel-mediated Ca2+ signals and contraction in fetal and adult sheep. AB - Long-term hypoxia (LTH) has a profound effect on pulmonary arterial vasoconstriction in the fetus and adult. Dysregulation in Ca2+ signaling is important during the development of LTH-induced pulmonary hypertension. In the present study, we tested the hypothesis that L-type Ca2+ channels (CaL), which are voltage dependent and found in smooth, skeletal, and cardiac muscle, are important in the adaptation of pulmonary arterial contractions in postnatal maturation and in response to LTH. Pulmonary arteries were isolated from fetal or adult sheep maintained at low or high altitude (3,801 m) for >100 days. The effects were measured using an L-type Ca2+ channel opener FPL 64176 (FPL) in the presence or absence of an inhibitor, Nifedipine (NIF) on arterial contractions, intracellular Ca2+ oscillations, and ryanodine receptor-driven Ca2+ sparks. FPL induced pulmonary arterial contractions in all groups were sensitive to NIF. However, when compared with 125 mM K+, FPL contractions were greater in fetuses than in adults. FPL reduced Ca2+ oscillations in myocytes of adult but not fetal arteries, independently of altitude. The FPL effects on Ca2+ oscillations were reversed by NIF in myocytes of hypoxic but not normoxic adults. FPL failed to enhance Ca2+ spark frequency and had little impact on spatiotemporal firing characteristics. These data suggest that CaL-dependent contractions are largely uncoupled from intracellular Ca2+ oscillations and the development of Ca2+ sparks. This raises questions regarding the coupling of pulmonary arterial contractility to membrane depolarization, attendant CaL facilitation, and the related associations with the activation of Ca2+ oscillations and Ca2+ sparks. PMID- 29167166 TI - Blood-borne interleukin-1beta acts on the subfornical organ to upregulate the sympathoexcitatory milieu of the hypothalamic paraventricular nucleus. AB - We previously reported that microinjection of the proinflammatory cytokine interleukin-1beta (IL-1beta) into the subfornical organ (SFO) elicits a pressor response accompanied by increases in inflammation and renin-angiotensin system (RAS) activity in the SFO and hypothalamic paraventricular nucleus (PVN). The present study sought to determine whether blood-borne IL-1beta induces similar neurochemical changes in the SFO and PVN and, if so, whether increased inflammation and RAS activity at the SFO level orchestrate the sympathoexcitatory response to circulating IL-1beta. In urethane-anesthetized male Sprague-Dawley rats, intravenous injection of IL-1beta (500 ng) increased blood pressure, heart rate, renal sympathetic nerve activity, and mRNA for angiotensin-converting enzyme, angiotensin II type 1a receptor, cyclooxygenase-2, tumor necrosis factor alpha, and IL-1beta, as well as the tumor necrosis factor-alpha p55 receptor and the IL-1 receptor, in the SFO and PVN. Pretreatment with SFO microinjections of the angiotensin II type 1a receptor blocker losartan (1 ug), the angiotensin converting enzyme inhibitor captopril (1 ug), or the cyclooxygenase-2 inhibitor NS-398 (2 ug) attenuated expression of these excitatory mediators in the SFO and downstream in the PVN and the IL-1beta-induced pressor responses. An SFO lesion minimized the IL-1beta-induced expression of inflammatory and RAS components as well as c-Fos, an indicator of neuronal excitation, in the PVN. These studies demonstrate that circulating IL-1beta, which increases in cardiovascular disorders such as hypertension and heart failure, acts on the SFO to increase inflammation and RAS activity in the SFO and PVN and that intervening in these neurochemical processes in the SFO can significantly reduce the sympathetic response.

AB - In the last decades, the contrast-enhanced micro-computed tomography (micro-CT) imaging of a whole animal kidney became increasingly important. The visualization was mainly limited to middle-sized vessels. Since modern desktop micro-CT scanners provide the necessary detail resolution, we developed an approach for rapid visualization and consistent assessment of kidney vasculature and glomeruli number. This method is based on MUAngiofil, a new polymerizing contrast agent with homogenous X-ray absorption, which provides continuous filling of the complete vasculature and enables correlative imaging approaches. For rapid and reliable kidney morphometry, the microangio-CT (uaCT) data sets from glial cell line-derived neurotrophic factor (GDNF)+/- mice and their wild-type littermates were used. The results were obtained much faster compared with the current gold standard, histology-based stereology, and without processing artifacts. The histology-based morphometry was done afterward on the same kidneys. Both approaches revealed that the GDNF+/- male mice had about 40% fewer glomeruli. Furthermore, our approach allows for the definition of sites of interest for further histological investigation, i.e., correlative morphology. The polymerized MUAngiofil stays in perfused vessels and is autofluorescent, which is what greatly facilitates the matching of histological sections with uaCT data. The presented approach is a time-efficient, reliable, qualitative, and quantitative methodology. Besides glomerular morphometry, the uaCT data can be used for qualitative and quantitative analysis of the kidney vasculature and correlative morphology.

AB - Obesity is an emerging pandemic driven by consumption of a diet rich in fat and highly refined carbohydrates (a Western diet) and a sedentary lifestyle in both children and adults. There is mounting evidence that arterial stiffness in obesity is an independent and strong predictor of cardiovascular disease (CVD), cognitive functional decline, and chronic kidney disease. Cardiovascular stiffness is a precursor to atherosclerosis, systolic hypertension, cardiac diastolic dysfunction, and impairment of coronary and cerebral flow. Moreover, premenopausal women lose the CVD protection normally afforded to them in the setting of obesity, insulin resistance, and diabetes, and this loss of CVD protection is inextricably linked to an increased propensity for arterial stiffness. Stiffness of endothelial and vascular smooth muscle cells, extracellular matrix remodeling, perivascular adipose tissue inflammation, and immune cell dysfunction contribute to the development of arterial stiffness in obesity. Enhanced endothelial cortical stiffness decreases endothelial generation of nitric oxide, and increased oxidative stress promotes destruction of nitric oxide. Our research over the past 5 years has underscored an important role of increased aldosterone and vascular mineralocorticoid receptor activation in driving development of cardiovascular stiffness, especially in females consuming a Western diet. In this review the cellular mechanisms of obesity-associated arterial stiffness are highlighted. PMID- 29167170 TI - Canagliflozin reduces plasma uremic toxins and alters the intestinal microbiota composition in a chronic kidney disease mouse model. AB - Accumulation of uremic toxins, which exert deleterious effects in chronic kidney disease, is influenced by the intestinal environment; the microbiota contributes to the production of representative uremic toxins, including p-cresyl sulfate and indoxyl sulfate. Canagliflozin is a sodium-glucose cotransporter (SGLT) 2 inhibitor, and it also exerts a modest inhibitory effect on SGLT1. The inhibition of intestinal SGLT1 can influence the gastrointestinal environment. We examined the effect of canagliflozin on the accumulation of uremic toxins in chronic kidney disease using adenine-induced renal failure mice. Two-week canagliflozin (10 mg/kg po) treatment did not influence the impaired renal function; however, it significantly reduced the plasma levels of p-cresyl sulfate and indoxyl sulfate in renal failure mice (a 75% and 26% reduction, respectively, compared with the vehicle group). Additionally, canagliflozin significantly increased cecal short-chain fatty acids in the mice, suggesting the promotion of bacterial carbohydrate fermentation in the intestine. Analysis of the cecal microbiota showed that canagliflozin significantly altered microbiota composition in the renal failure mice. These results indicate that canagliflozin exerts intestinal effects that reduce the accumulation of uremic toxins including p-cresyl sulfate. Reduction of accumulated uremic toxins by canagliflozin could provide a potential therapeutic option in chronic kidney disease. PMID- 29167171 TI - Advances in our understanding of the pathogenesis of hemolytic uremic syndromes. AB - Hemolytic uremic syndrome (HUS) is major global health care issue as it is the leading cause of acute kidney injury in children. It is a triad of acute kidney injury, microangiopathic hemolytic anemia, and thrombocytopenia. In recent years, major advances in our understanding of complement-driven inherited rare forms of HUS have been achieved. However, in children 90% of cases of HUS are associated with a Shiga toxin-producing enteric pathogen. The precise pathological mechanisms in this setting are yet to be elucidated. The purpose of this review is to discuss advances in our understanding of the pathophysiology underlying HUS and identify the key questions yet to be answered by the scientific community. PMID- 29167172 TI - Podocytes exhibit a specialized protein quality control employing derlin-2 in kidney disease. AB - Podocytes are terminally differentiated cells of the kidney filtration barrier with a limited proliferative capacity and are the primary glomerular target for various sources of cellular stress. Accordingly, it is particularly important for podocytes to cope with stress efficiently to circumvent cell death and avoid compromising renal function. Improperly folded proteins within the endoplasmic reticulum (ER) are associated with increased cellular injury and cell death. To relieve ER stress, protein quality control mechanisms like ER-associated degradation (ERAD) are initiated. Derlin-2 is an important dislocation channel component in the ERAD pathway, having an indispensable role in clearing misfolded glycoproteins from the ER lumen. With studies linking ER stress to kidney disease, we investigated the role of derlin-2 in the susceptibility of podocytes to injury due to protein misfolding. We show that podocytes employ derlin-2 to mediate the ER quality control system to maintain cellular homeostasis in both mouse and human glomeruli. Patients with focal segmental glomerulosclerosis (FSGS) or diabetic nephropathy (DN) upregulate derlin-2 expression in response to glomerular injury, as do corresponding mouse models. In derlin-2-deficient podocytes, compensatory responses were lost under adriamycin (ADR)-induced ER dysfunction, and severe cellular injury ensued via a caspase-12-dependent pathway. Moreover, derlin-2 overexpression in vitro attenuated ADR-induced podocyte injury. Thus derlin-2 is part of a protein quality control mechanism that can rescue glomerular injury attributable to impaired protein folding pathways in the ER. Induction of derlin-2 expression in vivo may have applications in prevention and treatment of glomerular diseases. PMID- 29167174 TI - Inherited bone marrow failure syndromes: considerations pre- and posttransplant. AB - Patients with inherited bone marrow failure syndromes are usually identified when they develop hematologic complications such as severe bone marrow failure, myelodysplastic syndrome, or acute myeloid leukemia. They often have specific birth defects or other physical abnormalities that suggest a syndrome, and sequencing of specific genes or next-generation sequencing can determine or confirm the particular syndrome. The 4 most frequent syndromes are Fanconi anemia, dyskeratosis congenita, Diamond Blackfan anemia, and Shwachman Diamond syndrome. This review discusses the major complications that develop as the patients with these syndromes age, as well as additional late effects following hematopoietic stem cell transplantation. The most common complications are iron overload in transfused patients and syndrome-specific malignancies in untransplanted patients, which may occur earlier and with higher risks in those who have received transplants. PMID- 29167175 TI - Signaling pathways and immune evasion mechanisms in classical Hodgkin lymphoma. AB - Classical Hodgkin lymphoma (cHL) is an unusual B-cell-derived malignancy in which rare malignant Hodgkin and Reed-Sternberg (HRS) cells are surrounded by an extensive but ineffective inflammatory/immune cell infiltrate. This striking feature suggests that malignant HRS cells escape immunosurveillance and interact with immune cells in the cancer microenvironment for survival and growth. We previously found that cHLs have a genetic basis for immune evasion: near-uniform copy number alterations of chromosome 9p24.1 and the associated PD-1 ligand loci, CD274/PD-L1 and PDCD1LG2/PD-L2, and copy number-dependent increased expression of these ligands. HRS cells expressing PD-1 ligands are thought to engage PD-1 receptor-positive immune effectors in the tumor microenvironment and induce PD-1 signaling and associated immune evasion. The genetic bases of enhanced PD-1 signaling in cHL make these tumors uniquely sensitive to PD-1 blockade.

PMID- 29167177 TI - Smoothened signaling in the mouse osteoblastoid lineage is required for efficient B lymphopoiesis. AB - The stromal signals that promote B lymphopoiesis remain poorly understood. Hedgehog (Hh) signaling promotes B lymphopoiesis in a non-cell-autonomous fashion in vitro, and depletion of the Hh effector Smoothened (Smo) from stromal cells is associated with the loss of osteoblastoid markers. These observations suggested that Hh signaling in the osteoblastoid lineage promotes B lymphopoiesis in vivo. To test this, we employed a mouse model for conditional ablation of Smo in the osteoblastoid lineage. Depletion of Smo from osteoblastoid cells is associated with profound and selective reductions in the number and proportion of bone marrow B-lymphoid progenitors. Upon partial bone marrow ablation, mutant animals exhibit delayed repopulation of the B-lymphoid compartment after the early lymphoid progenitor stage. Primary osteoblasts from mutant mice are defective in supporting B lymphopoiesis in vitro, whereas hematopoietic progenitors from mutant mice exhibit normal differentiation. We conclude that efficient B lymphopoiesis in vivo is dependent on the maintenance of Hh signaling in the osteoblastoid lineage.

AB - JGP study suggests the anion exchanger AE1 operates via an elevator-like mechanism. PMID- 29167179 TI - Proteinopathies and OXPHOS dysfunction in neurodegenerative diseases. AB - Mitochondria participate in essential processes in the nervous system such as energy and intermediate metabolism, calcium homeostasis, and apoptosis. Major neurodegenerative diseases are characterized pathologically by accumulation of misfolded proteins as a result of gene mutations or abnormal protein homeostasis. Misfolded proteins associate with mitochondria, forming oligomeric and fibrillary aggregates. As mitochondrial dysfunction, particularly of the oxidative phosphorylation system (OXPHOS), occurs in neurodegeneration, it is postulated that such defects are caused by the accumulation of misfolded proteins. However, this hypothesis and the pathological role of proteinopathies in mitochondria remain elusive. In this study, we critically review the proposed mechanisms whereby exemplary misfolded proteins associate with mitochondria and their consequences on OXPHOS. PMID- 29167180 TI - Asymmetry of inverted-topology repeats in the AE1 anion exchanger suggests an elevator-like mechanism. AB - The membrane transporter anion exchanger 1 (AE1), or band 3, is a key component in the processes of carbon-dioxide transport in the blood and urinary acidification in the renal collecting duct. In both erythrocytes and the basolateral membrane of the collecting-duct alpha-intercalated cells, the role of AE1 is to catalyze a one-for-one exchange of chloride for bicarbonate. After decades of biochemical and functional studies, the structure of the transmembrane region of AE1, which catalyzes the anion-exchange reaction, has finally been determined. Each protomer of the AE1 dimer comprises two repeats with inverted transmembrane topologies, but the structures of these repeats differ. This asymmetry causes the putative substrate-binding site to be exposed only to the extracellular space, consistent with the expectation that anion exchange occurs via an alternating-access mechanism. Here, we hypothesize that the unknown, inward-facing conformation results from inversion of this asymmetry, and we propose a model of this state constructed using repeat-swap homology modeling. By comparing this inward-facing model with the outward-facing experimental structure, we predict that the mechanism of AE1 involves an elevator-like motion of the substrate-binding domain relative to the nearly stationary dimerization domain and to the membrane plane. This hypothesis is in qualitative agreement with a wide range of biochemical and functional data, which we review in detail, and suggests new avenues of experimentation.

PMID- 29167183 TI - Evolution of subclinical myocardial dysfunction detected by two-dimensional and three-dimensional speckle tracking in asymptomatic type 1 diabetic patients: a long-term follow-up study. AB - BACKGROUND: We sought to assess the long-term evolution of left ventricular (LV) function using two-dimensional (2D) and three-dimensional (3D) speckle tracking echocardiography (STE) for the detection of preclinical diabetic cardiomyopathy, in asymptomatic type 1 diabetic patients, over a 6-year follow-up. DESIGN AND METHODS: Sixty-six asymptomatic type 1 diabetic patients with no cardiovascular risk factors were compared to 26 matched healthy controls. Conventional, 2D and 3D-STE were performed at baseline. A subgroup of 14 patients underwent a 6-year follow-up evaluation. RESULTS: At baseline, diabetic patients had similar LV ejection fraction (60 vs 61%; P = NS), but impaired longitudinal function, as assessed by 2D-global longitudinal strain (GLS) (-18.9 +/- 2 vs -20.5 +/- 2; P = 0.0002) and 3D-GLS (-17.5 +/- 2 vs -19 +/- 2; P = 0.003). At follow-up, diabetic patients had worsened longitudinal function compared to baseline (2D-GLS: -18.4 +/- 1 vs -19.2 +/- 1; P = 0.03). Global circumferential (GCS) and radial (GRS) strains were unchanged at baseline and during follow-up. Metabolic status did not correlate with GLS, whereas GCS and GRS showed a good correlation, suggestive of a compensatory increase of circumferential and radial functions in advanced stages of the disease - long-term diabetes (GCS: -26 +/- 3 vs -23.3 +/- 3; P = 0.008) and in the presence of microvascular complications (GRS: 38.8 +/- 9 vs 34.3 +/- 8; P = 0.04). CONCLUSIONS: Subclinical myocardial dysfunction can be detected by 2D and 3D-STE in type 1 diabetic patients, independently of any other cardiovascular risk factors. Diabetic cardiomyopathy progression was suggested by a mild decrease in longitudinal function at the follow-up, but did not extend to a clinical expression of the disease, as no death or over heart failure was reported.

AB - A 72-year-old man presented to the hospital with exacerbation of congestive heart failure. He was given furosemide 40 mg intravenously twice at 4 hours apart. At 4 hours after the second dose of furosemide, his white blood cells (WBC) dropped acutely from 9.8 to 2.4*109/L (reference range 4.1 to 9.3*109/L). With the discontinuation of furosemide, the WBC trended up to 7.1*109/L about 13 hours after the second dose of intravenous furosemide and remained in normal range for the next 3 days. However, when the oral furosemide was started on hospital day 4, there was a mild drop in WBC count, which returned to and maintained at baseline since the next day. The dynamic changes in the patient's WBC were coincident with the use of furosemide. The possible mechanisms of furosemide-associated transient hyperacute leucopenia were discussed.

PMID- 29167190 TI - An Outcomes-Based Definition of Proteinuria Remission in Focal Segmental Glomerulosclerosis. AB - BACKGROUND AND OBJECTIVES: Proteinuria is used as an indicator of FSGS disease activity, but its use as a clinical trial end point is not universally accepted. The goal of this study was to refine proteinuria definitions associated with long term kidney survival. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Data on 466 patients with primary FSGS with proteinuria (urine protein-to-creatinine ratio >1 g/g) were analyzed from five independent cohorts. Proteinuria by months 1, 4, and 8 after study baseline was categorized by conventional definitions of complete (<0.3 g/g) and partial remission (<3.5 g/g and 50% reduction in proteinuria). Novel remission definitions were explored using receiver operating curves. Kaplan Meier methods were used to estimate the associations of proteinuria with progression to ESRD or a 50% loss in kidney function. Propensity score-adjusted Cox proportional hazards models were used to adjust for baseline proteinuria, eGFR, and therapy. RESULTS: In the initial derivation cohort, conventional partial remission was not associated with kidney survival. A novel definition of partial remission (40% proteinuria reduction and proteinuria<1.5 g/g) on the basis of receiver operating curve analyses of 89 patients was identified (Sensitivity=0.70; Specificity=0.77). In the validation cohort analyses, complete remission was associated with better prognosis (6 out of 41 patients progressed to kidney failure; 6.6 per 100 patient-years) as was the novel partial remission (13 out of 71 progressed; 8.5 per 100 patient-years), compared with those with no response (51 out of 116 progressed; 20.1 per 100 patient-years). Conventional partial remission at month 8, but not month 4, was also associated with better response (19 out of 85 patients progressed; risk=10.4 per 100 patient-years). Propensity score-adjusted analyses showed the novel partial remission was associated with less progression at months 4 and 8 (month 4: hazard ratio, 0.50; P=0.01; month 8: hazard ratio, 0.30; P=0.002). CONCLUSIONS: Reaching either a complete or partial remission using a novel or conventional definition was associated with better long-term outcomes in patients with FSGS.

PMID- 29167191 TI - Nutritional status plays a crucial role in the mortality of critically ill patients with acute renal failure. AB - We aimed to clarify associations between nutritional status and mortality in patients with acute renal failure. De-identified data were obtained from the Medical Information Mart for Intensive Care III database comprising more than 40,000 critical care patients treated at Beth Israel Deaconess Medical Centerbetween 2001 and 2012. Weight loss and body mass index criteria were used to define malnutrition. Data of 193 critically ill patients with acute renal failure were analyzed, including demographics, nutrition intervention, laboratory results, and disease severity. Main outcomes were in-hospital and 1-year mortality. The 1-year mortality was significantly higher in those with malnutrition than in those without malnutrition (50.0% vs 29.3%, p=0.010), but differences in in-hospital survival were not significant (p=0.255). Significant differences in mortality were found between those with malnutrition and without starting at the 52nd day after intensive care unit (ICU) discharge (p=0.036). No significant differences were found between men and women with malnutrition in in hospital mortality (p=0.949) and 1-year mortality (p=0.051). Male patients requiring intervention with blood products/colloid supplements had greater risk of 1-year mortality, but without statistical significance. Nutritional status is a predictive factor for mortality among critically ill patients with acute renal failure, particularly 1-year mortality after ICU discharge. PMID- 29167189 TI - Photobiomodulation Inhibits Long-term Structural and Functional Lesions of Diabetic Retinopathy. AB - Previous studies demonstrated that brief (3 to 4 min) daily application of light at 670 nm to diabetic rodents inhibited molecular and pathophysiologic processes implicated in the pathogenesis of diabetic retinopathy (DR) and reversed diabetic macular edema in small numbers of patients studied. Whether or not this therapy would inhibit the neural and vascular lesions that characterize the early stages of the retinopathy was unknown. We administered photobiomodulation (PBM) therapy daily for 8 months to streptozotocin-diabetic mice and assessed effects of PBM on visual function, retinal capillary permeability, and capillary degeneration using published methods. Vitamin D receptor and Cyp24a1 transcripts were quantified by quantitative real-time PCR, and the abundance of c-Kit+ stem cells in blood and retina were assessed. Long-term daily administration of PBM significantly inhibited the diabetes-induced leakage and degeneration of retinal capillaries and also significantly inhibited the diabetes-induced reduction in visual function. PBM also inhibited diabetes-induced reductions in retinal Cyp24a1 mRNA levels and numbers of circulating stem cells (CD45-/c-Kit+), but these effects may not account for the beneficial effects of PBM on the retinopathy. PBM significantly inhibits the functional and histopathologic features of early DR, and these effects likely are mediated via multiple mechanisms. PMID- 29167192 TI - Cytokeratin-18 and enhanced liver fibrosis scores in type 1 and type 2 diabetes and effects of two different insulins. AB - Data on cytokeratin-18 (K-18) and enhanced liver fibrosis (ELF) score in insulin treated diabetes patients with non-alcoholic fatty liver disease (NAFLD) are limited. This study analyzed phase III data comparing basal insulin peglispro (BIL) and insulin glargine in type 1 (T1D), and type 2 diabetes (T2D) (insulin naive and insulin-treated). Alanine aminotransferase (ALT), K-18, ELF scores and liver fat content (LFC), measured by MRI, were obtained longitudinally. Baseline K-18 (U/L) was higher in T2D (range: 207-247) than T1D (range: 148-183), correlated with ALT in all populations (r (range) 0.264-0.637, p<0.05), but with LFC only in T2D (r (range) 0.474-0.586, p<0.05). K-18 increased significantly from baseline in BIL-treated, but not glargine-treated patients. Change from baseline (CFB) K-18 was significantly correlated with CFB in ALT in BIL-treated T2D populations. Baseline ELF scores were higher in T2D (range: 9.12-9.20) than T1D (range: 8.24-8.36), correlated with ALT in T1D only (0.209, p<0.05), and not correlated with LFC in any population. ELF scores increased significantly from baseline in BIL-treated but not glargine-treated patients. There were no correlations between CFB in LFC and ELF score at week 52 in any treatment group/population. In all BIL-treated populations, CFB in ALT and CFB in ELF score at week 52 were positively correlated. These data characterize associations of K 18 and ELF score with ALT and LFC in insulin-treated patients with T1D and T2D. Hepatopreferential insulins may be associated with increased K-18 and ELF scores but mechanisms and clinical significance are unknown. ClinicalTrials.gov identifiers are NCT01481779, NCT01435616, NCT01454284 and NCT01582451. PMID- 29167193 TI - Airway transplantation of adipose stem cells protects against bleomycin-induced pulmonary fibrosis. AB - Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease with poor prognosis. Adipose-derived stem cells (ADSC) have demonstrated regenerative properties in several tissues. The hypothesis of this study was that airway transplantation of ADSC could protect against bleomycin (BLM)-induced pulmonary fibrosis (PF). Fifty-eight lungs from 29 male Sprague-Dawley rats were analyzed. Animals were randomly divided into five groups: a) control (n=3); b) sham (n=6); c) BLM (n=6); d) BLM+ADSC-2d (n=6); and e) BLM+ADSC-14d (n=8). Animals received 500 uL saline (sham), 2.5 UI/kg BLM in 500 uL saline (BLM), and 2*106 ADSC in 100 uL saline intratracheally at 2 (BLM+ADSC-2d) and 14 days (BLM+ADSC-14d) after BLM. Animals were sacrificed at 28 days. Blinded Ashcroft score was used to determine pulmonary fibrosis extent on histology. Hsp27, Vegf, Nfkbeta, IL-1, IL-6, Col4, and Tgfbeta1 mRNA gene expression were determined using real-time quantitative-PCR. Ashcroft index was: control=0; sham=0.37+/ 0.07; BLM=6.55+/-0.34 vs sham (P=0.006). BLM vs BLM+ADSC-2d=4.63+/-0.38 (P=0.005) and BLM+ADSC-14d=3.77+/-0.46 (P=0.005). BLM vs sham significantly increased Hsp27 (P=0.018), Nfkbeta (P=0.009), Col4 (P=0.004), Tgfbeta1 (P=0.006) and decreased IL 1 (P=0.006). BLM+ADSC-2d vs BLM significantly decreased Hsp27 (P=0.009) and increased Vegf (P=0.006), Nfkbeta (P=0.009). BLM+ADSC-14d vs BLM significantly decreased Hsp27 (P=0.028), IL-6 (P=0.013), Col4 (P=0.002), and increased Nfkbeta (P=0.040) and Tgfbeta1 (P=0.002). Airway transplantation of ADSC significantly decreased the fibrosis rate in both early and established pulmonary fibrosis, modulating the expression of Hsp27, Vegfa, Nfkbeta, IL-6, Col4, and Tgfbeta1. From a translational perspective, this technique could become a new adjuvant treatment for patients with IPF.

AB - Antibodies against the central repeat of the Plasmodium falciparum (Pf) circumsporozoite protein (CSP) inhibit parasite activity and correlate with protection from malaria. However, the humoral response to the PfCSP C terminus (C PfCSP) is less well characterized. Here, we describe B cell responses to C-PfCSP from European donors who underwent immunization with live Pf sporozoites (PfSPZ Challenge) under chloroquine prophylaxis (PfSPZ-CVac), and were protected against controlled human malaria infection. Out of 215 PfCSP-reactive monoclonal antibodies, only two unique antibodies were specific for C-PfCSP, highlighting the rare occurrence of C-PfCSP-reactive B cells in PfSPZ-CVac-induced protective immunity. These two antibodies showed poor sporozoite binding and weak inhibition of parasite traversal and development, and did not protect mice from infection with PfCSP transgenic Plasmodium berghei sporozoites. Structural analyses demonstrated that one antibody interacts with a polymorphic region overlapping two T cell epitopes, suggesting that variability in C-PfCSP may benefit parasite escape from humoral and cellular immunity. Our data identify important features underlying C-PfCSP shortcomings as a vaccine target. PMID- 29167198 TI - Comparative transcriptome analysis reveals conserved branching morphogenesis related genes involved in chamber formation of catfish swimbladder. AB - The swimbladder is an internal gas-filled organ in teleosts. Its major function is to regulate buoyancy. The swimbladder exhibits great variation in size, shape, and number of compartments or chambers among teleosts. However, genomic control of swimbladder variation is unknown. Channel catfish ( Ictalurus punctatus), blue catfish ( Ictalurus furcatus), and their F1 hybrids of female channel catfish * male blue catfish (C * B hybrid catfish) provide a good model in which to investigate the swimbladder morphology, because channel catfish possess a single chambered swimbladder, whereas blue catfish possess a bichambered swimbladder; C * B hybrid catfish possess a bichambered swimbladder but with a significantly reduced posterior chamber. Here we determined the transcriptional profiles of swimbladder from channel catfish, blue catfish, and C * B hybrid catfish. We examined their transcriptomes at both the fingerling and adult stages. Through comparative transcriptome analysis, ~4,000 differentially expressed genes (DEGs) were identified. Among these DEGs, members of the Wnt signaling pathway ( wnt1, wnt2, nfatc1, rac2), Hedgehog signaling pathway ( shh), and growth factors ( fgf10, igf-1) were identified. As these genes were known to be important for branching morphogenesis of mammalian lung and of mammary glands, their association with budding of the posterior chamber primordium and progressive development of bichambered swimbladder in fish suggest that these branching morphogenesis-related genes and their functions in branching are evolutionarily conserved across a broad spectrum of species. PMID- 29167199 TI - The Germline-Specific Factor OEF-1 Facilitates Coordinated Progression Through Germ Cell Development in Caenorhabditis elegans. AB - The purpose of germ cells is to ensure the faithful transmission of genetic material to the next generation. To develop into mature gametes, germ cells must pass through cell cycle checkpoints while maintaining totipotency and genomic integrity. How germ cells coordinate developmental events while simultaneously protecting their unique fate is not well understood. Here, we characterize a novel nuclear protein, Oocyte-Excluded Factor-1 (OEF-1), with highly specific germline expression in Caenorhabditis elegans OEF-1 is initially detected early in embryogenesis and is expressed in the nuclei of all germ cells during larval stages. In adults, OEF-1 expression abruptly decreases just prior to oocyte differentiation. In oef-1 mutants, the developmental progression of germ cells is accelerated, resulting in subtle defects at multiple stages of germ cell development. Lastly, OEF-1 is primarily associated with the bodies of germline expressed genes, and as such is excluded from the X chromosome. We hypothesize that OEF-1 may regulate the rate of progression through germ cell development, providing insight into how these critical maturation events are coordinated. PMID- 29167200 TI - Assessing the Relationship of Ancient and Modern Populations. AB - Genetic material sequenced from ancient samples is revolutionizing our understanding of the recent evolutionary past. However, ancient DNA is often degraded, resulting in low coverage, error-prone sequencing. Several solutions exist to this problem, ranging from simple approach, such as selecting a read at random for each site, to more complicated approaches involving genotype likelihoods. In this work, we present a novel method for assessing the relationship of an ancient sample with a modern population, while accounting for sequencing error and postmortem damage by analyzing raw reads from multiple ancient individuals simultaneously. We show that, when analyzing SNP data, it is better to sequence more ancient samples to low coverage: two samples sequenced to 0.5* coverage provide better resolution than a single sample sequenced to 2* coverage. We also examined the power to detect whether an ancient sample is directly ancestral to a modern population, finding that, with even a few high coverage individuals, even ancient samples that are very slightly diverged from the modern population can be detected with ease. When we applied our approach to European samples, we found that no ancient samples represent direct ancestors of modern Europeans. We also found that, as shown previously, the most ancient Europeans appear to have had the smallest effective population sizes, indicating a role for agriculture in modern population growth.

AB - OBJECTIVE: To describe associations between alcoholic liver disease (ALD) or nonalcoholic fatty liver disease (NAFLD) hospital admission and cardiovascular disease (CVD), cancer, and mortality in people with type 2 diabetes mellitus (T2DM). RESEARCH DESIGN AND METHODS: We performed a retrospective cohort study by using linked population-based routine data from diabetes registry, hospital, cancer, and death records for people aged 40-89 years diagnosed with T2DM in Scotland between 2004 and 2013 who had one or more hospital admission records. Liver disease and outcomes were identified by using ICD-9 and ICD-10 codes. We estimated hazard ratios (HRs) from Cox proportional hazards regression models, adjusting for key risk factors. RESULTS: A total of 134,368 people with T2DM (1,707 with ALD and 1,452 with NAFLD) were studied, with a mean follow-up of 4.3 years for CVD and 4.7 years for mortality. Among those with ALD, NAFLD, or without liver disease hospital records 378, 320, and 21,873 CVD events; 268, 176, and 15,101 cancers; and 724, 221, and 16,203 deaths were reported, respectively. For ALD and NAFLD, respectively, adjusted HRs (95% CIs) compared with the group with no record of liver disease were 1.59 (1.43, 1.76) and 1.70 (1.52, 1.90) for CVD, 40.3 (28.8, 56.5) and 19.12 (11.71, 31.2) for hepatocellular carcinoma (HCC), 1.28 (1.12, 1.47) and 1.10 (0.94, 1.29) for non-HCC cancer, and 4.86 (4.50, 5.24) and 1.60 (1.40, 1.83) for all-cause mortality. CONCLUSIONS: Hospital records of ALD or NAFLD are associated to varying degrees with an increased risk of CVD, cancer, and mortality among people with T2DM.

AB - The timely diagnosis of aortic dissection is notoriously confounded by unreliable symptomatology. We present a previously unreported clinical sign: thoracic pain reproduced by abdominal palpation. Our case illustrates the dependence of traditional clinical features on the anatomical location of an aortic dissection and lends weight to the concept of aortic pain as being a dynamic product of inter-related changes in intraluminal pressure, volume, wall stress and diameter. The clinical sign we describe may be very specific of acute aortic pathology. PMID- 29167215 TI - Mid-aortic syndrome secondary to Takayasu's disease. AB - A 24-year-old young woman with good past health presented with hypertension during body check. Blood erythrocyte sedimentary rate level was elevated. CT and MR angiography revealed moderate stenosis of abdominal aorta and bilaterally renal arteries. She was diagnosed with mid-aortic syndrome caused by Takayasu arteritis based on clinical, radiological and pathological findings. She was treated with abdominal aorta resection, graft replacement and aorta-renal bypass. Pathology was compatible with Takayasu arteritis. Postoperatively, her blood pressure was normalised. She was prescribed with long-term prednisolone and aspirin for her arteritis. PMID- 29167213 TI - Interaction of Dietary and Genetic Factors Influencing Body Iron Status and Risk of Type 2 Diabetes Within the EPIC-InterAct Study. AB - OBJECTIVE: Meat intake has been consistently shown to be positively associated with incident type 2 diabetes. Part of that association may be mediated by body iron status, which is influenced by genetic factors. We aimed to test for interactions of genetic and dietary factors influencing body iron status in relation to the risk of incident type 2 diabetes. RESEARCH DESIGN AND METHODS: The case-cohort comprised 9,347 case subjects and 12,301 subcohort participants from eight European countries. Single nucleotide polymorphisms (SNPs) were selected from genome-wide association studies on iron status biomarkers and candidate gene studies. A ferritin-related gene score was constructed. Multiplicative and additive interactions of heme iron and SNPs as well as the gene score were evaluated using Cox proportional hazards regression. RESULTS: Higher heme iron intake (per 1 SD) was associated with higher ferritin levels (beta = 0.113 [95% CI 0.082; 0.144]), but not with transferrin (-0.019 [-0.043; 0.006]) or transferrin saturation (0.016 [-0.006; 0.037]). Five SNPs located in four genes (rs1799945 [HFE H63D], rs1800562 [HFE C282Y], rs236918 [PCK7], rs744653 [SLC40A1], and rs855791 [TMPRSS6 V736A]) were associated with ferritin. We did not detect an interaction of heme iron and the gene score on the risk of diabetes in the overall study population (Padd = 0.16, Pmult = 0.21) but did detect a trend toward a negative interaction in men (Padd = 0.04, Pmult = 0.03). CONCLUSIONS: We found no convincing evidence that the interplay of dietary and genetic factors related to body iron status associates with type 2 diabetes risk above the level expected from the sum or product of the two individual exposures.

AB - Pneumothorax and pulmonary embolism (PE) are two life-threatening causes of shortness of breath in patients presenting to the emergency department. A rare but more serious presentation is that of simultaneous PE and pneumothorax. We present the case of a young patient, with no known comorbidities, who presented with simultaneous submassive PE and pneumothorax. We will review how these two diagnoses may be related, consider the implications of having this dual diagnosis on the patient's management and review the current evidence surrounding thrombolysis in submassive PE.

AB - 5-Fluorouracil (5-FU), a commonly used antimetabolite and antineoplastic agent, has been approved for treatment of various cancers. Neurotoxicities are considered extremely rare side effects of 5-FU. We present a case of 5-FU-induced encephalopathy with diffusion-restricted reversible lesion of the splenium of the corpus callosum in a patient with colorectal cancer. The patient presented with confusion, dysarthria and agitation after 5-FU infusion. The prognosis of this toxic effects of 5-FU is usually good if recognised and treated in time. Emergency physicians, general practitioners and oncologists should be aware of this rare side effects of 5-FU chemotherapy and its diagnosis and treatment.

AB - We describe the case of a 50-year-old woman presenting to our acute medicine department with generalised non-specific symptoms on a background of HIV managed on triple therapy (tenofovir, lamivudine and zidovudine). On admission, she was noted to be acidotic with proteinuria, glycosuria, hypophosphataemia and generalised body pain, and was diagnosed with Fanconi's renotubular syndrome secondary to tenofovir. It was also noted that she had elevated liver dysfunction markers, and an MRI of the liver revealed a focal stricture near the ampulla of Vater, resulting in a diagnosis of AIDS cholangiopathy. These two diagnoses are rare complications of HIV, and the presence of both these pathologies in a single patient has never been reported in the literature before, and we therefore believe that this case is the first of its kind.

AB - A 20-year-old woman was brought to the surgery emergency department with the complaint of epigastric pain since 1 day following ingestion of multiple metallic nails with a cup full of toilet cleaner (corrosive acid) with a suicidal intention. Physical examination was essentially unremarkable, and the abdomen showed no signs of perforation peritonitis. X-rays of the abdomen showed multiple 'nail'-like radiopaque shadows in the abdominal cavity with no evidence of free gas under the domes of the diaphragm. A non-operative expectant management was pursued. The patient had passed all the sharps in stools without any complication and was discharged after 12 days. After 3 weeks, the patient presented with non bilious vomiting. Further investigations revealed pyloric stenosis with no oesophageal luminal stenosis. To bypass the pyloric stenosis, a Billroth II gastrojejunostomy was performed. The postoperative period was uneventful, and the recovery was smooth.

AB - A 71-year-old woman presented to the emergency department 8 days after ingesting fish with mild neck pain but otherwise demonstrated no signs of infection. X-rays were negative but CT imaging demonstrated a curvilinear radiodense object extending from the posterior cervical oesophagus through the right thyroid lobe terminating in the neck just a few millimetres from the external carotid artery. Rigid oesophagoscopy and direct laryngoscopy were negative and the neck was explored for the foreign body, which ultimately was encountered after a painstaking dissection of the right neck that included skeletonisation of the recurrent laryngeal nerve. Her postoperative recovery was uneventful and after a 3-day course of intravenous antibiotics she was discharged on oral antibiotics, in good condition and tolerating a soft diet.

PMID- 29167223 TI - Graduate Training at the Interface of Computational and Experimental Biology: An Outcome Report from a Partnership of Volunteers between a University and a National Laboratory. AB - Leading voices in the biological sciences have called for a transformation in graduate education leading to the PhD degree. One area commonly singled out for growth and innovation is cross-training in computational science. In 1998, the University of Tennessee (UT) founded an intercollegiate graduate program called the UT-ORNL Graduate School of Genome Science and Technology in partnership with the nearby Oak Ridge National Laboratory. Here, we report outcome data that attest to the program's effectiveness in graduating computationally enabled biologists for diverse careers. Among 77 PhD graduates since 2003, the majority came with traditional degrees in the biological sciences, yet two-thirds moved into computational or hybrid (computational-experimental) positions. We describe the curriculum of the program and how it has changed. We also summarize how the program seeks to establish cohesion between computational and experimental biologists. This type of program can respond flexibly and dynamically to unmet training needs. In conclusion, this study from a flagship, state-supported university may serve as a reference point for creating a stable, degree-granting, interdepartmental graduate program in computational biology and allied areas. PMID- 29167224 TI - Implementation of a Learning Assistant Program Improves Student Performance on Higher-Order Assessments. AB - Learning assistant (LA) programs have been implemented at a range of institutions, usually as part of a comprehensive curricular transformation accompanied by a pedagogical switch to active learning. While this shift in pedagogy has led to increased student learning gains, the positive effect of LAs has not yet been distinguished from that of active learning. To determine the effect that LAs would have beyond a student-centered instructional modality that integrated active learning, we introduced an LA program into a large-enrollment introductory molecular biology course that had already undergone a pedagogical transformation to a highly structured, flipped (HSF) format. We used questions from a concept test (CT) and exams to compare student performance in LA-supported HSF courses with student performance in courses without LAs. Students in the LA supported course did perform better on exam questions common to both HSF course modalities but not on the CT. In particular, LA-supported students' scores were higher on common exam questions requiring higher-order cognitive skills, which LAs were trained to foster. Additionally, underrepresented minority (URM) students particularly benefited from LA implementation. These findings suggest that LAs may provide additional learning benefits to students beyond the use of active learning, especially for URM students. PMID- 29167225 TI - A Call to Use Cultural Competence When Teaching Evolution to Religious College Students: Introducing Religious Cultural Competence in Evolution Education (ReCCEE). AB - Low acceptance of evolution among undergraduate students is common and is best predicted by religious beliefs. Decreasing students' perceived conflict between religion and evolution could increase their acceptance of evolution. However, college biology instructors may struggle with trying to decrease students' perceived conflict between religion and evolution because of differences in the religious cultures and beliefs of instructors and students. Although a large percentage of undergraduate students in evolution courses are religious, most instructors teaching evolution are not. To consider differences between the secular culture of many college instructors and the religious culture of many students, we propose using a lens of cultural competence to create effective evolution education. Cultural competence is the ability of individuals from one culture (in this case, primarily secular instructors who are teaching evolution) to bridge cultural differences and effectively communicate with individuals from a different culture (in this case, primarily religious undergraduate biology students). We call this new framework Religious Cultural Competence in Evolution Education (ReCCEE). In this essay, we describe a suite of culturally competent practices that can help instructors reduce students' perceived conflict between evolution and religion, increase students' acceptance of evolution, and help create more inclusive undergraduate biology classrooms. PMID- 29167226 TI - Surgical Enlargement of the Aortic Root Does Not Increase the Operative Risk of Aortic Valve Replacement. AB - BACKGROUND: Surgical aortic root enlargement (ARE) during aortic valve replacement (AVR) allows for larger prosthesis implantation and may be an important adjunct to surgical AVR in the transcatheter valve-in-valve era. The incremental operative risk of adding ARE to AVR has not been established. We aimed to evaluate the early outcomes of patients undergoing AVR with or without ARE. METHODS: From January 1990 to August 2014, 7039 patients underwent AVR (AVR+ARE, n=1854; AVR, n=5185) at a single institution. Patients with aortic dissection and active endocarditis were excluded. Mean age was 65+/-14 years and 63% were male. Logistic regression and propensity score matching were used to adjust for unbalanced variables in group comparisons. RESULTS: Patients undergoing AVR+ARE were more likely to be female (46% versus 34%, P<0.001) and had higher rates of previous cardiac surgery (18% versus 12%, P<0.001), chronic obstructive pulmonary disease (5% versus 3%, P=0.004), urgent/emergent status (6% versus 4%, P=0.01), and worse New York Heart Association status (P<0.001). Most patients received bioprosthetic valves (AVR+ARE: 73.4% versus AVR: 73.3%, P=0.98) and also underwent concomitant cardiac procedures (AVR+ARE: 68% versus AVR: 67%, P=0.31). Mean prosthesis size implanted was slightly smaller in patients requiring AVR+ARE versus AVR (23.4+/-2.1 versus 24.1+/-2.3, P<0.001). In-hospital mortality was higher after AVR+ARE (4.3% versus 3.0%, P=0.008), although when the cohort was restricted to patients undergoing isolated aortic valve replacement with or without root enlargement, mortality was not statistically different (AVR+ARE: 1.7% versus AVR: 1.1%, P=0.29). After adjustment for baseline characteristics, AVR+ARE was not associated with an increased risk of in-hospital mortality when compared with AVR (odds ratio, 1.03; 95% confidence interval, 0.75 1.41; P=0.85). Furthermore, AVR+ARE was not associated with an increased risk of postoperative adverse events. Results were similar if propensity matching was used instead of multivariable adjustments for baseline characteristics. CONCLUSIONS: In the largest analysis to date, ARE was not associated with increased risk of mortality or adverse events. Surgical ARE is a safe adjunct to AVR in the modern era. PMID- 29167227 TI - Pericardial Adipose Tissue Regulates Granulopoiesis, Fibrosis, and Cardiac Function After Myocardial Infarction. AB - BACKGROUND: The pericardial adipose tissue (AT) contains a high density of lymphoid clusters. It is unknown whether these clusters play a role in post myocardial infarction (MI) inflammatory responses and cardiac outcome. METHODS: Lymphoid clusters were examined in epicardial AT of humans with or without coronary artery disease. Murine pericardial lymphoid clusters were visualized in mice subjected to coronary artery ligation. To study the relevance of pericardial clusters during inflammatory responses after MI, we surgically removed the pericardial AT and performed B-cell depletion and granulocyte-macrophage colony stimulating factor blockade. Leukocytes in murine hearts, pericardial AT, spleen, mediastinal lymph nodes, and bone marrow were quantified by flow cytometry. Cannabinoid receptor CB2 (CB2-/-) mice were used as a model for enhanced B-cell responses. The effect of impaired dendritic cell (DC) trafficking on pericardial AT inflammatory responses was tested in CCR7-/- mice subjected to MI. Cardiac fibrosis and ventricular function were assessed by histology and echocardiography. RESULTS: We identified larger B-cell clusters in epicardial AT of human patients with coronary artery disease in comparison with controls without coronary artery disease. Infarcted mice also had larger pericardial clusters and 3-fold upregulated numbers of granulocyte-macrophage colony stimulating factor-producing B cells within pericardial AT, but not spleen or lymph nodes. This was associated with higher DC and T-cell counts in pericardial AT, which outnumbered DCs and T cells in lymph nodes. Analysis of DC maturation markers, tracking experiments with fluorescently labeled cells, and use of CCR7 deficient mice suggested that activated DCs migrate from infarcts into pericardial AT via CCR7. B-cell depletion or granulocyte-macrophage colony stimulating factor neutralization inhibited DC and T-cell expansion within pericardial AT, and translated into reduced bone marrow granulopoiesis and cardiac neutrophil infiltration 3 days after MI. The relevance of the pericardial AT in mediating all these effects was confirmed by removal of pericardial AT and ex vivo coculture with pericardial AT and granulocyte progenitors. Finally, enhanced fibrosis and worsened ejection fraction in CB2-/- mice were limited by pericardial AT removal. CONCLUSIONS: Our findings unveil a new mechanism by which the pericardial AT coordinates immune cell activation, granulopoiesis, and outcome after MI. PMID- 29167228 TI - Contribution of Impaired Parasympathetic Activity to Right Ventricular Dysfunction and Pulmonary Vascular Remodeling in Pulmonary Arterial Hypertension. AB - BACKGROUND: The beneficial effects of parasympathetic stimulation have been reported in left heart failure, but whether it would be beneficial for pulmonary arterial hypertension (PAH) remains to be explored. Here, we investigated the relationship between parasympathetic activity and right ventricular (RV) function in patients with PAH, and the potential therapeutic effects of pyridostigmine (PYR), an oral drug stimulating the parasympathetic activity through acetylcholinesterase inhibition, in experimental pulmonary hypertension (PH). METHODS: Heart rate recovery after a maximal cardiopulmonary exercise test was used as a surrogate for parasympathetic activity. RV ejection fraction was assessed in 112 patients with PAH. Expression of nicotinic (alpha-7 nicotinic acetylcholine receptor) and muscarinic (muscarinic acetylcholine type 2 receptor) receptors, and acetylcholinesterase activity were evaluated in RV (n=11) and lungs (n=7) from patients with PAH undergoing heart/lung transplantation and compared with tissue obtained from controls. In addition, we investigated the effects of PYR (40 mg/kg per day) in experimental PH. PH was induced in male rats by SU5416 (25 mg/kg subcutaneously) injection followed by 4 weeks of hypoxia. In a subgroup, sympathetic/parasympathetic modulation was assessed by power spectral analysis. At week 6, PH status was confirmed by echocardiography, and rats were randomly assigned to vehicle or treatment (both n=12). At the end of the study, echocardiography was repeated, with additional RV pressure-volume measurements, along with lung, RV histological, and protein analyses. RESULTS: Patients with PAH with lower RV ejection fraction (<41%) had a significantly reduced heart rate recovery in comparison with patients with higher RV ejection fraction. In PAH RV samples, alpha-7 nicotinic acetylcholine receptor was increased and acetylcholinesterase activity was reduced versus controls. No difference in muscarinic acetylcholine type 2 receptor expression was observed. Chronic PYR treatment in PH rats normalized the cardiovascular autonomic function, demonstrated by an increase in parasympathetic activity and baroreflex sensitivity. PYR improved survival, increased RV contractility, and reduced RV stiffness, RV hypertrophy, RV fibrosis, RV inflammation, and RV alpha-7 nicotinic acetylcholine receptor and muscarinic acetylcholine type 2 receptor expression, as well. Furthermore, PYR reduced pulmonary vascular resistance, RV afterload, and pulmonary vascular remodeling, which was associated with reduced local and systemic inflammation. CONCLUSIONS: RV dysfunction is associated with reduced systemic parasympathetic activity in patients with PAH, with an inadequate adaptive response of the cholinergic system in the RV. Enhancing parasympathetic activity by PYR improved survival, RV function, and pulmonary vascular remodeling in experimental PH. PMID- 29167229 TI - Embryonic Lethality and Host Immunity of RelA-Deficient Mice Are Mediated by Both Apoptosis and Necroptosis. AB - In mammalian cells, signaling pathways triggered by TNF can be switched from NF kappaB activation to apoptosis and/or necroptosis. The in vivo mechanisms underlying the mutual regulation of these three signaling pathways are poorly understood. In this article, we report that the embryonic lethality of RelA deficient mice is partially prevented by the deletion of Rip3 or Mlkl, but it is fully rescued by the combined ablation of Fadd and Rip3 or Mlkl or by blocking RIP1 kinase activity (RIP1K45A). RelA-/-Fadd-/-Rip3-/- triple-knockout (TKO) and RelA-/-Rip1K45A/K45A mice displayed bacterial pneumonia leading to death ~2 wk after birth. Moreover, RelA-/-Rip1K45A/K45A mice, but not TKO mice, developed severe inflammation associated with inflammatory skin lesion. Antibiotic treatment improved bacterial pneumonia, extended the lifespan of TKO and RelA-/ Rip1K45A/K45A mice, and alleviated skin inflammation in RelA-/-Rip1K45A/K45A mice. These results show the mechanisms underlying the in vivo mutual regulation between NF-kappaB activation and the cell death pathway and provide new insights into this interplay in embryonic development and host immune homeostasis. PMID- 29167231 TI - Reticulon-1 and Reduced Migration toward Chemoattractants by Macrophages Differentiated from the Bone Marrow of Ultraviolet-Irradiated and Ultraviolet Chimeric Mice. AB - The ability of macrophages to respond to chemoattractants and inflammatory signals is important for their migration to sites of inflammation and immune activity and for host responses to infection. Macrophages differentiated from the bone marrow (BM) of UV-irradiated mice, even after activation with LPS, migrated inefficiently toward CSF-1 and CCL2. When BM cells were harvested from UV irradiated mice and transplanted into naive mice, the recipient mice (UV chimeric) had reduced accumulation of elicited monocytes/macrophages in the peritoneal cavity in response to inflammatory thioglycollate or alum. Macrophages differentiating from the BM of UV-chimeric mice also had an inherent reduced ability to migrate toward chemoattractants in vitro, even after LPS activation. Microarray analysis identified reduced reticulon-1 mRNA expressed in macrophages differentiated from the BM of UV-chimeric mice. By using an anti-reticulon-1 Ab, a role for reticulon-1 in macrophage migration toward both CSF-1 and CCL2 was confirmed. Reticulon-1 subcellular localization to the periphery after exposure to CSF-1 for 2.5 min was shown by immunofluorescence microscopy. The proposal that reduced reticulon-1 is responsible for the poor inherent ability of macrophages to respond to chemokine gradients was supported by Western blotting. In summary, skin exposure to erythemal UV radiation can modulate macrophage progenitors in the BM such that their differentiated progeny respond inefficiently to signals to accumulate at sites of inflammation and immunity. PMID- 29167230 TI - Absence of CD59 in Guinea Pigs: Analysis of the Cavia porcellus Genome Suggests the Evolution of a CD59 Pseudogene. AB - CD59 is a membrane-bound regulatory protein that inhibits the assembly of the terminal membrane attack complex (C5b-9) of complement. From its original discovery in humans almost 30 years ago, CD59 has been characterized in a variety of species, from primates to early vertebrates, such as teleost fish. CD59 is ubiquitous in mammals; however, we have described circumstantial evidence suggesting that guinea pigs (Cavia porcellus) lack CD59, at least on erythrocytes. In this study, we have used a combination of phylogenetic analyses with syntenic alignment of mammalian CD59 genes to identify the only span of genomic DNA in C. porcellus that is homologous to a portion of mammalian CD59 and show that this segment of DNA is not transcribed. We describe a pseudogene sharing homology to exons 2 through 5 of human CD59 present in the C. porcellus genome. This pseudogene was flanked by C. porcellus homologs of two genes, FBXO3 and ORF91, a relationship and orientation that were consistent with other known mammalian CD59 genes. Analysis using RNA sequencing confirmed that this segment of chromosomal DNA was not transcribed. We conclude that guinea pigs lack an intact gene encoding CD59; to our knowledge, this is the first report of a mammalian species that does not express a functional CD59. The pseudogene we describe is likely the product of a genomic deletion event during its evolutionary divergence from other members of the rodent order. PMID- 29167232 TI - Identification of IFN-gamma and IL-27 as Critical Regulators of Respiratory Syncytial Virus-Induced Exacerbation of Allergic Airways Disease in a Mouse Model. AB - Respiratory syncytial virus (RSV) infection induces asthma exacerbations, which leads to worsening of clinical symptoms and may result in a sustained decline in lung function. Exacerbations are the main cause of morbidity and mortality associated with asthma, and significantly contribute to asthma-associated healthcare costs. Although glucocorticoids are used to manage exacerbations, some patients respond to them poorly. The underlying mechanisms associated with steroid-resistant exacerbations remain largely unknown. We have previously established a mouse model of RSV-induced exacerbation of allergic airways disease, which mimics hallmark clinical features of asthma. In this study, we have identified key roles for macrophage IFN-gamma and IL-27 in the regulation of RSV-induced exacerbation of allergic airways disease. Production of IFN-gamma and IL-27 was steroid-resistant, and neutralization of IFN-gamma or IL-27 significantly suppressed RSV-induced steroid-resistant airway hyperresponsiveness and airway inflammation. We have previously implicated activation of pulmonary macrophage by TNF-alpha and/or MCP-1 in the mechanisms of RSV-induced exacerbation. Stimulation of pulmonary macrophages with TNF-alpha and/or MCP-1 induced expression of both IFN-gamma and IL-27. Our findings highlight critical roles for IFN-gamma and IL-27, downstream of TNF-alpha and MCP-1, in the mechanism of RSV-induced exacerbation. Thus, targeting the pathways that these factors activate may be a potential therapeutic approach for virus-induced asthma exacerbations. PMID- 29167234 TI - Route of Antigen Presentation Can Determine the Selection of Foxp3-Dependent or Foxp3-Independent Dominant Immune Tolerance. AB - It has been shown that dominant tolerance, namely in transplantation, requires Foxp3+ regulatory T cells. Although most tolerance-inducing regimens rely on regulatory T cells, we found that induction of tolerance to proteins in aluminum hydroxide can be achieved in Foxp3-deficient mice using nondepleting anti-CD4 Abs. This type of tolerance is Ag specific, and tolerant mice retain immune competence to respond to unrelated Ags. We demonstrated with chicken OVA-specific TCR-transgenic mice that the same tolerizing protocol (CD4 blockade) and the same target Ag (OVA) achieves Foxp3-dependent transplantation tolerance to OVA expressing skin grafts, but Foxp3-independent tolerance when the Ag is provided as OVA-aluminum hydroxide. In the latter case, we found that tolerance induction triggered recessive mechanisms leading to elimination of effector cells and, simultaneously, a dominant mechanism associated with the emergence of an anergic and regulatory CTLA-4+IL-2lowFoxp3- T cell population, where the tolerance state is IL-10 dependent. Such Foxp3-independent mechanisms can improve the efficacy of tolerance-inducing protocols. PMID- 29167233 TI - Granzyme A in Human Platelets Regulates the Synthesis of Proinflammatory Cytokines by Monocytes in Aging. AB - Dysregulated inflammation is implicated in the pathobiology of aging, yet platelet-leukocyte interactions and downstream cytokine synthesis in aging remains poorly understood. Platelets and monocytes were isolated from healthy younger (age <45, n = 37) and older (age >=65, n = 30) adults and incubated together under autologous and nonautologous conditions. Synthesis of inflammatory cytokines by monocytes, alone or in the presence of platelets, was examined. Next generation RNA-sequencing allowed for unbiased profiling of the platelet transcriptome in aging. Basal IL-8 and MCP-1 synthesis by monocytes alone did not differ between older and younger adults. However, in the presence of autologous platelets, monocytes from older adults synthesized greater IL-8 (41 +/- 5 versus 9 +/- 2 ng/ml, p < 0.0001) and MCP-1 (867 +/- 150 versus 216 +/- 36 ng/ml, p < 0.0001) than younger adults. Platelets from older adults were sufficient for upregulating the synthesis of inflammatory cytokines by monocytes. Using RNA sequencing of platelets followed by validation via RT-PCR and immunoblot, we discovered that granzyme A (GrmA), a serine protease not previously identified in human platelets, increases with aging (~9-fold versus younger adults, p < 0.05) and governs increased IL-8 and MCP-1 synthesis through TLR4 and caspase-1. Inhibiting GrmA reduced excessive IL-8 and MCP-1 synthesis in aging to levels similar to younger adults. In summary, human aging is associated with changes in the platelet transcriptome and proteome. GrmA is present and bioactive in human platelets, is higher in older adults, and controls the synthesis of inflammatory cytokines by monocytes. Alterations in the platelet molecular signature and signaling to monocytes may contribute to dysregulated inflammatory syndromes in older adults. PMID- 29167235 TI - Cortisol limits selected actions of synthetic glucocorticoids in the airway epithelium. AB - Cortisol, a physiologic glucocorticoid (GC), is essential for growth and differentiation of the airway epithelium. Epithelial function influences inflammation in chronic respiratory diseases. Synthetic GCs, including inhaled corticosteroids, exert anti-inflammatory effects in airway epithelium by transactivation of genes and by inhibition of proinflammatory cytokine release. We examined the effect of cortisol on the actions of synthetic GCs in the airway epithelium, demonstrating that cortisol acts like a partial agonist at the GC receptor (GR), limiting GC-induced GR-dependent transcription in the BEAS-2B human bronchial epithelial cell line. Cortisol also limited the inhibition of granulocyte macrophage colony-stimulating factor release by synthetic GCs in TNF alpha-activated BEAS-2B cells. The relevance of these findings is supported by observations on tracheal epithelium obtained from mice treated for 5 d with systemic GC, showing limitations in selected GC effects, including inhibition of IL-6. Moreover, gene transactivation by synthetic GCs was compromised by standard air-liquid interface (ALI) growth medium cortisol concentration (1.4 MUM) in the ALI-differentiated organotypic culture of primary human airway epithelial cells. These findings suggest that endogenous corticosteroids may limit certain actions of synthetic pharmacological GCs and contribute to GC insensitivity, particularly when corticosteroid levels are elevated by stress.-Prodanovic, D., Keenan, C.

AB - RNA processing bodies (P-bodies) are cytoplasmic RNA granules in eukaryotic cells that regulate gene expression by executing the translation suppression and degradation of mRNAs that are targeted to these bodies. P-bodies can also serve as storage sites for translationally repressed mRNAs both in mammalian cells and yeast cells. In this report, a unique role of mammalian P-bodies is documented. Depletion of P-body components dedifferentiate nerve growth factor-treated PC12 cells, whereas ectopic expression of P-body components induces the neuronal differentiation of precursor cells. Trophic factor withdrawal from differentiated cells induces a decrease in cellular P-body size and numbers that are coupled with dedifferentiation and cell death. Here, we report how the expression of P body proteins-by ensuring the phosphorylation of argonaute protein 2 and the subsequent inactivation let-7a miRNPs-prevents the apoptotic death of growth factor-depleted neuronal cells.-Patranabis, S., Bhattacharyya, S.

AB - BACKGROUND: In February 2012, a reformulated tamper-deterrent form of long-acting oxycodone, OxyNeo, was introduced in Canada. We investigated the impact of the introduction of OxyNeo on patterns of opioid prescribing. METHODS: We conducted population-based, cross-sectional analyses of opioid dispensing in Canada between 2008 and 2016. We estimated monthly community pharmacy dispensing of oral formulations of codeine, morphine, hydromorphone and oxycodone, and a transdermal formulation of fentanyl, and converted quantities to milligrams of morphine equivalents (MMEs) per 1000 population. We used time series analysis to evaluate the effect of the introduction of OxyNeo on these trends. RESULTS: National dispensing of long-acting opioids fell by 14.9% between February 2012 and April 2016, from 36 098 MMEs to 30 716 MMEs per 1000 population (p < 0.01). This effect varied across Canada and was largest in Ontario (reduction of 22.8%) (p = 0.01) and British Columbia (reduction of 30.0%) (p = 0.01). The national rate of oxycodone dispensing fell by 46.4% after the introduction of OxyNeo (p < 0.001); this was partially offset by an increase of 47.8% in hydromorphone dispensing (p < 0.001). Although dispensing of immediate-release opioids was a substantial contributor to overall population opioid exposure across Canada, it was unaffected by the introduction of OxyNeo (p > 0.05 in all provinces). INTERPRETATION: The findings suggest that the introduction of a tamper-deterrent formulation of long-acting oxycodone in Canada, against a background of changing public drug benefits, was associated with sustained changes in selection of long acting opioids but only small changes in the quantity of long-acting opioids dispensed. This illustrates the limited effect a tamper-deterrent formulation and associated coverage policy can have when other, non-tamper-deterrent alternatives are readily available.

PMID- 29167268 TI - The shaker-1 mouse myosin VIIa deafness mutation results in a severely reduced rate of the ATP hydrolysis step. AB - Mutations in the MYO7A gene, encoding the motor protein myosin VIIa, can cause Usher 1B, a deafness/blindness syndrome in humans, and the shaker-1 phenotype, characterized by deafness, head tossing, and circling behavior, in mice. Myosin VIIa is responsible for tension bearing and the transduction mechanism in the stereocilia and for melanosome transport in the retina, in line with the phenotypic outcomes observed in mice. However, the effect of the shaker-1 mutation, a R502P amino acid substitution, on the motor function is unclear. To explore this question, we determined the kinetic properties and the effect on the filopodial tip localization of the recombinant mouse myosin VIIa-5IQ-SAH R502P (myoVIIa-sh1) construct. Interestingly, although residue 502 is localized to a region thought to be involved in interacting with actin, the kinetic parameters for actin binding changed only slightly for the mutant construct. However, the rate constant for ATP hydrolysis (k+H + k-H) was reduced by ~200-fold from 12 s-1 to 0.05 s-1, making the hydrolysis step the rate-limiting step of the ATPase cycle in the presence and absence of actin. Given that wild-type mouse myosin VIIa is a slow, high-duty ratio, monomeric motor, this altered hydrolysis rate would reduce activity to extremely low levels. Indeed, the translocation to the filopodial tips was hampered by the diminished motor function of a dimeric construct of the shaker-1 mutant. We conclude that the diminished motor activity of this mutant is most likely responsible for impaired hearing in the shaker-1 mice. PMID- 29167269 TI - Ring finger protein 126 (RNF126) suppresses ionizing radiation-induced p53 binding protein 1 (53BP1) focus formation. AB - Cells have evolved sophisticated mechanisms to maintain genomic integrity in response to DNA damage. Ionizing radiation (IR)-induced DNA damage results in the formation of IR-induced foci (iRIF) in the nucleus. The iRIF formation is part of the DNA damage response (DDR), which is an essential signaling cascade that must be strictly regulated because either the loss of or an augmented DDR leads to loss of genome integrity. Accordingly, negative regulation of the DDR is as critical as its activation. In this study, we have identified ring finger protein 126 (RNF126) as a negative regulator of the DDR from a screen of iRIF containing 53BP1. RNF126 overexpression abolishes not only the formation of 53BP1 iRIF but also of RNF168, FK2, RAP80, and BRCA1. However, the iRIF formation of gammaH2AX, MDC1, and RNF8 is maintained, indicating that RNF126 acts between RNF8 and RNF168 during the DDR. In addition, RNF126 overexpression consistently results in the loss of RNF168-mediated H2A monoubiquitination at lysine 13/15 and inhibition of the non-homologous end joining capability. Taken together, our findings reveal that RNF126 is a novel factor involved in the negative regulation of DDR, which is important for sustaining genomic integrity. PMID- 29167270 TI - UbiA prenyltransferase domain-containing protein-1 modulates HMG-CoA reductase degradation to coordinate synthesis of sterol and nonsterol isoprenoids. AB - UBIAD1 (UbiA prenyltransferase domain-containing protein-1) utilizes geranylgeranyl pyrophosphate (GGpp) to synthesize vitamin K2 We previously reported that sterols stimulate binding of UBIAD1 to endoplasmic reticulum (ER) localized 3-hydroxy-3-methylglutaryl (HMG) CoA reductase. UBIAD1 binding inhibits sterol-accelerated, ER-associated degradation (ERAD) of reductase, one of several mechanisms for feedback control of this rate-limiting enzyme in the branched pathway that produces cholesterol and nonsterol isoprenoids such as GGpp. Accumulation of GGpp in ER membranes triggers release of UBIAD1 from reductase, permitting its maximal ERAD and ER-to-Golgi transport of UBIAD1. Mutant UBIAD1 variants associated with Schnyder corneal dystrophy (SCD), a human disorder characterized by corneal accumulation of cholesterol, resist GGpp-induced release from reductase and remain sequestered in the ER to block reductase ERAD. Using lines of genetically manipulated cells, we now examine consequences of UBIAD1 deficiency and SCD-associated UBIAD1 on reductase ERAD and cholesterol synthesis. Our results indicated that reductase becomes destabilized in the absence of UBIAD1, resulting in reduced cholesterol synthesis and intracellular accumulation. In contrast, an SCD-associated UBIAD1 variant inhibited reductase ERAD, thereby stabilizing the enzyme and contributing to enhanced synthesis and intracellular accumulation of cholesterol. Finally, we present evidence that GGpp regulated, ER-to-Golgi transport enables UBIAD1 to modulate reductase ERAD such that synthesis of nonsterol isoprenoids is maintained in sterol-replete cells. These findings further establish UBIAD1 as a central player in the reductase ERAD pathway and regulation of isoprenoid synthesis. They also indicate that UBIAD1 mediated inhibition of reductase ERAD underlies cholesterol accumulation associated with SCD. PMID- 29167271 TI - Reference Assembly and Annotation of the Pyrenophora teres f. teres Isolate 0-1. AB - Pyrenophora teres f. teres, the causal agent of net form net blotch (NFNB) of barley, is a destructive pathogen in barley-growing regions throughout the world. Typical yield losses due to NFNB range from 10 to 40%; however, complete loss has been observed on highly susceptible barley lines where environmental conditions favor the pathogen. Currently, genomic resources for this economically important pathogen are limited to a fragmented draft genome assembly and annotation, with limited RNA support of the P. teres f. teres isolate 0-1. This research presents an updated 0-1 reference assembly facilitated by long-read sequencing and scaffolding with the assistance of genetic linkage maps. Additionally, genome annotation was mediated by RNAseq analysis using three infection time points and a pure culture sample, resulting in 11,541 high-confidence gene models. The 0-1 genome assembly and annotation presented here now contains the majority of the repetitive content of the genome. Analysis of the 0-1 genome revealed classic characteristics of a "two-speed" genome, being compartmentalized into GC equilibrated and AT-rich compartments. The assembly of repetitive AT-rich regions will be important for future investigation of genes known as effectors, which often reside in close proximity to repetitive regions. These effectors are responsible for manipulation of the host defense during infection. This updated P. teres f. teres isolate 0-1 reference genome assembly and annotation provides a robust resource for the examination of the barley-P. teres f. teres host-pathogen coevolution. PMID- 29167272 TI - Direct Testing for Allele-Specific Expression Differences Between Conditions. AB - Allelic imbalance (AI) indicates the presence of functional variation in cis regulatory regions. Detecting cis regulatory differences using AI is widespread, yet there is no formal statistical methodology that tests whether AI differs between conditions. Here, we present a novel model and formally test differences in AI across conditions using Bayesian credible intervals. The approach tests AI by environment (G*E) interactions, and can be used to test AI between environments, genotypes, sex, and any other condition. We incorporate bias into the modeling process. Bias is allowed to vary between conditions, making the formulation of the model general. As gene expression affects power for detection of AI, and, as expression may vary between conditions, the model explicitly takes coverage into account. The proposed model has low type I and II error under several scenarios, and is robust to large differences in coverage between conditions. We reanalyze RNA-seq data from a Drosophila melanogaster population panel, with F1 genotypes, to compare levels of AI between mated and virgin female flies, and we show that AI * genotype interactions can also be tested. To demonstrate the use of the model to test genetic differences and interactions, a formal test between two F1s was performed, showing the expected 20% difference in AI. The proposed model allows a formal test of G*E and G*G, and reaffirms a previous finding that cis regulation is robust between environments. PMID- 29167273 TI - Restorer-of-Fertility Mutations Recovered in Transposon-Active Lines of S Male Sterile Maize. AB - Mitochondria execute key pathways of central metabolism and serve as cellular sensing and signaling entities, functions that depend upon interactions between mitochondrial and nuclear genetic systems. This is exemplified in cytoplasmic male sterility type S (CMS-S) of Zea mays, where novel mitochondrial open reading frames are associated with a pollen collapse phenotype, but nuclear restorer-of fertility (restorer) mutations rescue pollen function. To better understand these genetic interactions, we screened Activator-Dissociation (Ac-Ds), Enhancer/Suppressor-mutator (En/Spm), and Mutator (Mu) transposon-active CMS-S stocks to recover new restorer mutants. The frequency of restorer mutations increased in transposon-active stocks compared to transposon-inactive stocks, but most mutants recovered from Ac-Ds and En/Spm stocks were unstable, reverting upon backcrossing to CMS-S inbred lines. However, 10 independent restorer mutations recovered from CMS-S Mu transposon stocks were stable upon backcrossing. Many restorer mutations condition seed-lethal phenotypes that provide a convenient test for allelism. Eight such mutants recovered in this study included one pair of allelic mutations that were also allelic to the previously described rfl2-1 mutant. Targeted analysis of mitochondrial proteins by immunoblot identified two features that consistently distinguished restored CMS-S pollen from comparably staged, normal-cytoplasm, nonmutant pollen: increased abundance of nuclear encoded alternative oxidase relative to mitochondria-encoded cytochrome oxidase and decreased abundance of mitochondria-encoded ATP synthase subunit 1 compared to nuclear-encoded ATP synthase subunit 2. CMS-S restorer mutants thus revealed a metabolic plasticity in maize pollen, and further study of these mutants will provide new insights into mitochondrial functions that are critical to pollen and seed development. PMID- 29167274 TI - Distinct Cellular Mechanisms Underlie Smooth Muscle Turnover in Vascular Development and Repair. AB - RATIONALE: Vascular smooth muscle turnover has important implications for blood vessel repair and for the development of cardiovascular diseases, yet lack of specific transgenic animal models has prevented it's in vivo analysis. OBJECTIVE: The objective of this study was to characterize the dynamics and mechanisms of vascular smooth muscle turnover from the earliest stages of embryonic development to arterial repair in the adult. METHODS AND RESULTS: We show that CD146 is transiently expressed in vascular smooth muscle development. By using CRISPR-Cas9 genome editing and in vitro smooth muscle differentiation assay, we demonstrate that CD146 regulates the balance between proliferation and differentiation. We developed a triple-transgenic mouse model to map the fate of NG2+CD146+ immature smooth muscle cells. A series of pulse-chase experiments revealed that the origin of aortic vascular smooth muscle cells can be traced back to progenitor cells that reside in the wall of the dorsal aorta of the embryo at E10.5. A distinct population of CD146+ smooth muscle progenitor cells emerges during embryonic development and is maintained postnatally at arterial branch sites. To characterize the contribution of different cell types to arterial repair, we used 2 injury models. In limited wire-induced injury response, existing smooth muscle cells are the primary contributors to neointima formation. In contrast, microanastomosis leads to early smooth muscle death and subsequent colonization of the vascular wall by proliferative adventitial cells that contribute to the repair. CONCLUSIONS: Extensive proliferation of immature smooth muscle cells in the primitive embryonic dorsal aorta establishes the long-lived lineages of smooth muscle cells that make up the wall of the adult aorta. A discrete population of smooth muscle cells forms in the embryo and is postnatally sustained at arterial branch sites. In response to arterial injuries, existing smooth muscle cells give rise to neointima, but on extensive damage, they are replaced by adventitial cells.

AB - Purpose: Intratumoral androgen synthesis (IAS) is a key mechanism promoting androgen receptor (AR) reactivation and antiandrogen resistance in castration resistant prostate cancer (CRPC). However, signaling pathways driving aberrant IAS remain poorly understood.Experimental Design: The effect of components of the AKT-RUNX2-osteocalcin (OCN)-GPRC6A-CREB signaling axis on expression of steroidogenesis genes CYP11A1 and CYP17A1 and testosterone level were examined in PTEN-null human prostate cancer cell lines. Pten knockout mice were used to examine the effect of Runx2 heterozygous deletion or abiraterone acetate (ABA), a prodrug of the CYP17A1 inhibitor abiraterone on Cyp11a1 and Cyp17a1 expression, testosterone level and tumor microenvironment (TME) remodeling in vivoResults: We uncovered that activation of the AKT-RUNX2-OCN-GPRC6A-CREB signaling axis induced expression of CYP11A1 and CYP17A1 and testosterone production in PTEN-null prostate cancer cell lines in culture. Deletion of Runx2 in Pten homozygous knockout prostate tumors decreased Cyp11a1 and Cyp17a1 expression, testosterone level, and tumor growth in castrated mice. ABA treatment also inhibited testosterone synthesis and alleviated Pten loss-induced tumorigenesis in vivoPten deletion induced TME remodeling, but Runx2 heterozygous deletion or ABA treatment reversed the effect of Pten loss by decreasing expression of the collagenase Mmp9.Conclusions: Abnormal RUNX2 activation plays a pivotal role in PTEN loss induced IAS and TME remodeling, suggesting that the identified signaling cascade represents a viable target for effective treatment of PTEN-null prostate cancer, including CRPC.

We aimed to predict the IDH status of gliomas from MR imaging by applying a residual convolutional neural network to preoperative radiographic data.Experimental Design: Preoperative imaging was acquired for 201 patients from the Hospital of University of Pennsylvania (HUP), 157 patients from Brigham and Women's Hospital (BWH), and 138 patients from The Cancer Imaging Archive (TCIA) and divided into training, validation, and testing sets. We trained a residual convolutional neural network for each MR sequence (FLAIR, T2, T1 precontrast, and T1 postcontrast) and built a predictive model from the outputs. To increase the size of the training set and prevent overfitting, we augmented the training set images by introducing random rotations, translations, flips, shearing, and zooming.Results: With our neural network model, we achieved IDH prediction accuracies of 82.8% (AUC = 0.90), 83.0% (AUC = 0.93), and 85.7% (AUC = 0.94) within training, validation, and testing sets, respectively. When age at diagnosis was incorporated into the model, the training, validation, and testing accuracies increased to 87.3% (AUC = 0.93), 87.6% (AUC = 0.95), and 89.1% (AUC = 0.95), respectively.Conclusions: We developed a deep learning technique to noninvasively predict IDH genotype in grade II-IV glioma using conventional MR imaging using a multi-institutional data set.

AB - Background: Thyroid cancer is the most rapidly increasing cancer in the United States, affects a young population, has high survival, and is one of the most common cancers in people under age 40. The aim of this study was to examine the risks of aging-related diseases in a statewide sample of thyroid cancer survivors who were diagnosed <40 years compared with those diagnosed >=40 and a cancer-free sample.Methods: Thyroid cancer survivors diagnosed 1997 to 2012 were matched to up to 5 cancer-free individuals on birth year, sex, birth state, using the statewide Utah Population Database. Medical records were used to identify disease diagnoses stratified over three time periods: 1 to 5, >5 to 10, and 10+ years after cancer diagnosis. Cox proportional hazards models were used to estimate hazard ratios with adjustment on matching factors, race, body mass index, and Charlson Comorbidity Index.Results: There were 3,706 thyroid cancer survivors and 15,587 matched cancer-free individuals (1,365 cases diagnosed <40 years old). Both age groups had increased risks for multiple circulatory health conditions 1 to 5 years after cancer diagnosis compared with cancer-free individuals. Survivors <40 had a higher risk of hypertension, cardiomyopathy, and nutritional deficiencies.Conclusions: Increased risks for diseases associated with aging were observed for both age groups, with younger thyroid cancer survivors having higher risks for select diseases.Impact: As thyroid cancer survivors in this study were found to have increased risks for aging-related diseases, future studies are needed to assess what can be done to reduce the increased risks of these long term health effects.

AB - To survive and proliferate, cells have to faithfully segregate their newly replicated genomic DNA to the two daughter cells. However, the sister chromatids of mitotic chromosomes are frequently interlinked by so-called ultrafine DNA bridges (UFBs) that are visible in the anaphase of mitosis. UFBs can only be detected by the proteins bound to them and not by staining with conventional DNA dyes. These DNA bridges are presumed to represent entangled sister chromatids and hence pose a threat to faithful segregation. A failure to accurately unlink UFB DNA results in chromosome segregation errors and binucleation. This, in turn, compromises genome integrity, which is a hallmark of cancer. UFBs are actively removed during anaphase, and most known UFB-associated proteins are enzymes involved in DNA repair in interphase. However, little is known about the mitotic activities of these enzymes or the exact DNA structures present on UFBs. We focus on the biology of UFBs, with special emphasis on their underlying DNA structure and the decatenation machineries that process UFBs. PMID- 29167278 TI - Blood Pressure Status in Adult Survivors of Childhood Cancer: A Report from the St. Jude Lifetime Cohort Study. AB - Background: Hypertension potentiates cardiovascular risk in survivors of childhood cancer previously exposed to cardiotoxic therapies, so it is important to determine the prevalence and risk factors for hypertensive blood pressure in this high-risk group.Methods: Participants included 3,016 adult 10-year survivors of childhood cancer who had resting blood pressure measurements performed at St. Jude Children's Research Hospital (Memphis, TN). We characterized the blood pressure status of participants, calculated standardized prevalence ratios based on U.S. population rates, and examined demographic and treatment factors associated with hypertensive blood pressure using logistic regression.Results: The age-specific cumulative prevalence of hypertension in survivors increased sharply with age, exceeding 70% by age 50, and was substantially higher in all diagnosis groups than expected on the basis of age-, sex-, race/ethnicity-, and BMI-specific population rates. Specific cancer treatments were not significantly associated with hypertension, with the exception of nephrectomy (OR, 1.68; 95% confidence interval, 1.11-2.53). Previously undiagnosed hypertensive blood pressure was identified in 8% of survivors, and uncontrolled hypertension in 22% of those with a previous hypertension diagnosis. In a subset (n = 1,185) with longitudinal blood pressure measurements (mean interval, 3.6 years), 5% and 21% of participants with previously normal blood pressure developed hypertensive and prehypertensive blood pressure, respectively.Conclusions: Survivors of childhood cancer have a higher prevalence of hypertension compared with the general population, and many have uncontrolled hypertension that may exacerbate treatment related cardiovascular risks.Impact: Our results suggest enhanced clinical attention to blood pressure status is warranted in all survivors, regardless of diagnosis or cancer treatment.

AB - Polytene chromosomes have for 80 years provided the highest resolution view of interphase genome structure in an animal cell nucleus. These chromosomes represent the normal genomic state of nearly all Drosophila larval and many adult cells, and a better understanding of their striking banded structure has been sought for decades. A more recently appreciated characteristic of Drosophila polytene cells is somatic genome instability caused by unfinished replication (UR). Repair of stalled forks generates enough deletions in polytene salivary gland cells to alter 10%-90% of the DNA strands within more than 100 UR regions comprising 20% of the euchromatic genome. We accurately map UR regions and show that most approximate large polytene bands, indicating that replication forks frequently stall near band boundaries in late S phase. Chromosome conformation capture has recently identified dense topologically associated domains (TADs) in many genomes and most UR bands are similar or slightly smaller than a cognate Drosophila TAD. We argue that bands serve the evolutionarily ancient function of coordinating genome replication with local gene activity. We also discuss the relatively recent evolution of polyteny and somatic instability in Diptera and propose that these processes helped propel the amazing success of two-winged flies in becoming the most ecologically diverse insect group, with 200 times the number of species as mammals. PMID- 29167279 TI - Height, Obesity, and the Risk of TMPRSS2:ERG-Defined Prostate Cancer. AB - Background: The largest molecular subtype of primary prostate cancer is defined by the TMPRSS2:ERG gene fusion. Few studies, however, have investigated etiologic differences by TMPRSS2:ERG status. Because the fusion is hormone-regulated and a man's hormonal milieu varies by height and obesity status, we hypothesized that both may be differentially associated with risk of TMPRSS2:ERG-defined disease.Methods: Our study included 49,372 men from the prospective Health Professionals Follow-up Study. Participants reported height and weight at baseline in 1986 and updated weight biennially thereafter through 2009. Tumor ERG protein expression (a TMPRSS2:ERG marker) was immunohistochemically assessed. We used multivariable competing risks models to calculate HRs and 95% confidence intervals (CIs) for the risk of ERG-positive and ERG-negative prostate cancer.Results: During 23 years of follow-up, we identified 5,847 incident prostate cancers, among which 913 were ERG-assayed. Taller height was associated with an increased risk of ERG-positive disease only [per 5 inches HR 1.24; 95% confidence interval (CI), 1.03-1.50; Pheterogeneity = 0.07]. Higher body mass index (BMI) at baseline (per 5 kg/m2 HR 0.75; 95% CI, 0.61-0.91; Pheterogeneity = 0.02) and updated BMI over time (per 5 kg/m2 HR 0.86; 95% CI, 0.74-1.00; Pheterogeneity = 0.07) were associated with a reduced risk of ERG-positive disease only.Conclusions: Our results indicate that anthropometrics may be uniquely associated with TMPRSS2:ERG-positive prostate cancer; taller height may be associated with greater risk, whereas obesity may be associated with lower risk.Impact: Our study provides strong rationale for further investigations of other prostate cancer risk factors that may be distinctly associated with subtypes.

AB - In eukaryotes, genomic DNA is hierarchically packaged by histones into chromatin on several levels to fit inside the nucleus. As a central-level structure between nucleosomal arrays and higher-order chromatin organizations, the 30-nm chromatin fiber and its dynamics play a crucial role in gene regulation. However, despite considerable efforts over the past three decades, the fundamental structure and its dynamic regulation of chromatin fibers still remain as a big challenge in molecular biology. Here, we mainly summarize the most recent progress in elucidating the structure of the 30-nm chromatin fiber in vitro and epigenetic regulation of chromatin fibers by chromatin factors, particularly histone variants. In addition, we also discuss recent studies in unraveling the three dimensional organization of chromatin fibers in situ by genomic approaches and electron microscopy. PMID- 29167283 TI - RotoStep: A Chromosome Dynamics Simulator Reveals Mechanisms of Loop Extrusion. AB - ChromoShake is a three-dimensional simulator designed to explore the range of configurational states a chromosome can adopt based on thermodynamic fluctuations of the polymer chain. Here, we refine ChromoShake to generate dynamic simulations of a DNA-based motor protein such as condensin walking along the chromatin substrate. We model walking as a rotation of DNA-binding heat-repeat proteins around one another. The simulation is applied to several configurations of DNA to reveal the consequences of mechanical stepping on taut chromatin under tension versus loop extrusion on single-tethered, floppy chromatin substrates. These simulations provide testable hypotheses for condensin and other DNA-based motors functioning along interphase chromosomes. Our model reveals a novel mechanism for condensin enrichment in the pericentromeric region of mitotic chromosomes. Increased condensin dwell time at centromeres results in a high density of pericentric loops that in turn provide substrate for additional condensin. PMID- 29167284 TI - Molecular Structures of Yeast Kinetochore Subcomplexes and Their Roles in Chromosome Segregation. AB - Kinetochore molecular architecture exemplifies "form follows function." The simplifications that generated the one-chromosome:one-microtubule linkage in point-centromere yeast have enabled strategies for systematic structural analysis and high-resolution visualization of many kinetochore components, leading to specific proposals for molecular mechanisms. We describe here some structural features that allow a kinetochore to remain attached to the end of a depolymerizing microtubule (MT) and some characteristics of the connections between substructures that permit very sensitive regulation by differential kinase activities. We emphasize in particular the importance of flexible connections between rod-like structural members and the integration of these members into a compliant cage-like assembly anchored on the MT by a sliding molecular ring. PMID- 29167285 TI - Macrophagic "Crown-like Structures" Are Associated with an Increased Risk of Breast Cancer in Benign Breast Disease. AB - In breast adipose tissue, macrophages that encircle damaged adipocytes form "crown-like structures of breast" (CLS-B). Although CLS-B have been associated with breast cancer, their role in benign breast disease (BBD) and early carcinogenesis is not understood. We evaluated breast biopsies from three age matched groups (n = 86 each, mean age 55 years), including normal tissue donors of the Susan G. Komen for the Cure Tissue Bank (KTB), and subjects in the Mayo Clinic Benign Breast Disease Cohort who developed cancer (BBD cases) or did not develop cancer (BBD controls, median follow-up 14 years). Biopsies were classified into histologic categories, and CD68-immunostained tissue sections were evaluated for the frequency and density of CLS-B. Our data demonstrate that CLS-B are associated with BBD: CLS-B-positive samples were significantly less frequent among KTB biopsies (3/86, 3.5%) than BBD controls (16/86 = 18.6%, P = 0.01) and BBD cases (21/86 = 24%, P = 0.002). CLS-B were strongly associated with body mass index (BMI); BMI < 25: 7% CLS-B positive, BMI 25-29: 13%, and BMI >= 30: 29% (P = 0.0005). Among BBD biopsies, a high CLS-B count [>5 CLS-B/sample: 10.5% (BBD cases) vs 4.7% (BBD controls), P = 0.007] conferred a breast cancer OR of 6.8 (95% CI, 1.4-32.4), P = 0.02, after adjusting for adipose tissue area (cm2), histologic impression, and BMI. As high CLS-B densities are independently associated with an increased breast cancer risk, they may be a promising histologic marker of breast cancer risk in BBD. Cancer Prev Res; 11(2); 113-9.

AB - Paroxysmal kinesigenic dyskinesia (PKD) is a rare neurological disorder characterized by recurrent attacks of dyskinetic movements without alteration of consciousness that are often triggered by the initiation of voluntary movements. Whole-exome sequencing has revealed a cluster of pathogenic variants in PRRT2 (proline-rich transmembrane protein), a gene with a function in synaptic regulation that remains poorly understood. Here, we report the discovery of a novel PRRT2 pathogenic variant inherited in an autosomal dominant pattern in a family with PKD and benign familial infantile seizures (BFIS). After targeted Sanger sequencing did not identify the presence of previously described PRRT2 pathogenic variants, we carried out whole-exome sequencing in the proband and her affected paternal grandfather. This led to the discovery of a novel PRRT2 variant, NM_001256442:exon3:c.C959T/NP_660282.2:p.A320V, altering an evolutionarily conserved alanine at the amino acid position 320 located in the M2 transmembrane region. Sanger sequencing further confirmed the presence of this variant in four affected family members (paternal grandfather, father, brother, and proband) and its absence in two unaffected ones (paternal grandmother and mother). This newly found variant further reinforces the importance of PRRT2 in PKD, BFIS, and possibly other movement disorders. Future functional studies using animal models and human pluripotent stem cell models will provide new insights into the role of PRRT2 and the significance of this variant in regulating neural development and/or function. PMID- 29167287 TI - U.S. High-Level Isolation Unit Clinical Laboratory Capabilities Update. AB - In late 2014, 56 hospitals in the United States were designated by state and federal public health authorities as specially designed high-level isolation units (HLIUs) equipped with advanced infrastructure, laboratory capabilities, and trained staff to care for patients with highly hazardous communicable diseases (HHCDs), such as Ebola virus disease. This survey describes the clinical laboratory support capabilities of U.S. HLIUs, including the specific test menus that HLIUs have identified to safely manage HHCD patients and the locations where such testing would be performed. In spring 2016, a survey was electronically distributed, as a fillable pdf file, to the 56 U.S. HLIUs. Site representatives completed the surveys, and data were coded and analyzed in an electronic spreadsheet, using descriptive statistics. Thirty-six HLIUs (64%) responded, and 33 completed the laboratory capabilities section. Thirty-one HLIUs (94%) had performed risk analyses for all laboratory procedures and equipment. Twenty-nine (88%) had decontamination procedures specified for all laboratory equipment used for patients with suspected or confirmed HHCDs. On-site laboratories in 27 HLIUs (81%) had the capacity to inventory and to securely store HHCD patient specimens. Ten HLIUs (31%) had at least one test they would conduct within the patient isolation room. The high-risk nature of HHCDs and the occupational exposures that may occur in clinical laboratories demand advanced preparation and risk assessment of work practices, laboratory equipment, and instrumentation by HLIU laboratories. Although risk analyses of clinical laboratory testing and equipment that HLIUs have conducted have likely focused on those for Ebola virus, HLIUs must be prepared to revise their current procedures for other HHCDs. PMID- 29167288 TI - A Predominant Variable-Number Tandem-Repeat Cluster of Mycobacterium tuberculosis Isolates among Asylum Seekers in the Netherlands and Denmark, Deciphered by Whole Genome Sequencing. AB - In many countries, Mycobacterium tuberculosis isolates are routinely subjected to variable-number tandem-repeat (VNTR) typing to investigate M. tuberculosis transmission. Unexpectedly, cross-border clusters were identified among African refugees in the Netherlands and Denmark, although transmission in those countries was unlikely. Whole-genome sequencing (WGS) was applied to analyze transmission in depth and to assess the precision of VNTR typing. WGS was applied to 40 M. tuberculosis isolates from refugees in the Netherlands and Denmark (most of whom were from the Horn of Africa) that shared the exact same VNTR profile. Cluster investigations were undertaken to identify in-country epidemiological links. Combining WGS results for the isolates (all members of the central Asian strain [CAS]/Delhi genotype), from both European countries, an average genetic distance of 80 single-nucleotide polymorphisms (SNPs) (maximum, 153 SNPs) was observed. The few pairs of isolates with confirmed epidemiological links, except for one pair, had a maximum distance of 12 SNPs. WGS divided this refugee cluster into several subclusters of patients from the same country of origin. Although the M. tuberculosis cases, mainly originating from African countries, shared the exact same VNTR profile, most were clearly distinguished by WGS. The average genetic distance in this specific VNTR cluster was 2 times greater than that in other VNTR clusters. Thus, identical VNTR profiles did not represent recent direct M. tuberculosis transmission for this group of patients. It appears that either these strains from Africa are extremely conserved genetically or there is ongoing transmission of this genotype among refugees on their long migration routes from Africa to Europe.

AB - The Copan ESwab system was evaluated for its ability to maintain the viability of pathogenic fungi. Tests followed the Clinical and Laboratory Standards Institute (CLSI) document M40-A2 roll-plate method at room and refrigerator temperatures. A system was devised for standardizing homogeneous inoculum suspensions of variously sized conidia and sporangiospores of filamentous fungi. A total of 19 clinical and reference strains were standardized to a 0.5 McFarland turbidity standard with a simple photometer. Corresponding optical densities were measured with a spectrophotometer. Colony counts equal to or greater than those seen at time zero were obtained for the entire test panel. Results indicate that the Copan ESwab system effectively maintains prevalent opportunistic fungal organisms for at least 48 h. PMID- 29167290 TI - Evaluation of Whole-Genome Sequencing for Mycobacterial Species Identification and Drug Susceptibility Testing in a Clinical Setting: a Large-Scale Prospective Assessment of Performance against Line Probe Assays and Phenotyping. AB - Use of whole-genome sequencing (WGS) for routine mycobacterial species identification and drug susceptibility testing (DST) is becoming a reality. We compared the performances of WGS and standard laboratory workflows prospectively, by parallel processing at a major mycobacterial reference service over the course of 1 year, for species identification, first-line Mycobacterium tuberculosis resistance prediction, and turnaround time. Among 2,039 isolates with line probe assay results for species identification, 74 (3.6%) failed sequencing or WGS species identification. Excluding these isolates, clinically important species were identified for 1,902 isolates, of which 1,825 (96.0%) were identified as the same species by WGS and the line probe assay. A total of 2,157 line probe test results for detection of resistance to the first-line drugs isoniazid and rifampin were available for 728 M. tuberculosis complex isolates. Excluding 216 (10.0%) cases where there were insufficient sequencing data for WGS to make a prediction, overall concordance was 99.3% (95% confidence interval [CI], 98.9 to 99.6%), sensitivity was 97.6% (91.7 to 99.7%), and specificity was 99.5% (99.0 to 99.7%). A total of 2,982 phenotypic DST results were available for 777 M. tuberculosis complex isolates. Of these, 356 (11.9%) had no WGS comparator due to insufficient sequencing data, and in 154 (5.2%) cases the WGS prediction was indeterminate due to discovery of novel, previously uncharacterized mutations. Excluding these data, overall concordance was 99.2% (98.7 to 99.5%), sensitivity was 94.2% (88.4 to 97.6%), and specificity was 99.4% (99.0 to 99.7%). Median processing times for the routine laboratory tests versus WGS were similar overall, i.e., 20 days (interquartile range [IQR], 15 to 31 days) and 21 days (15 to 29 days), respectively (P = 0.41). In conclusion, WGS predicts species and drug susceptibility with great accuracy, but work is needed to increase the proportion of predictions made.

Recent reports highlight ongoing challenges due to organism misidentification, high rates of antifungal drug resistance, and significant patient mortality.

This minireview details the global emergence of C. auris and discusses issues relevant to clinical microbiology laboratories, hospital infection control, and antimicrobial stewardship efforts. PMID- 29167292 TI - Clinical Evaluation of the Cepheid Xpert TV Assay for Detection of Trichomonas vaginalis with Prospectively Collected Specimens from Men and Women. AB - Trichomoniasis is the most prevalent curable sexually transmitted disease (STD). It has been associated with preterm birth and the acquisition and transmission of HIV. Recently, nucleic acid amplification tests (NAAT) have been FDA cleared in the United States for detection of Trichomonas vaginalis in specimens from both women and men. This study reports the results of a multicenter study recently conducted using the Xpert TV (T. vaginalis) assay to test specimens from both men and women. On-demand results were available in as little as 40 min for positive specimens. A total of 1,867 women and 4,791 men were eligible for inclusion in the analysis. In women, the performance of the Xpert TV assay was compared to the patient infected status (PIS) derived from the results of InPouch TV broth culture and Aptima NAAT for T. vaginalis The diagnostic sensitivities and specificities of the Xpert TV assay for the combined female specimens (urine samples, self-collected vaginal swabs, and endocervical swabs) ranged from 99.5 to 100% and 99.4 to 99.9%, respectively. For male urine samples, the diagnostic sensitivity and specificity were 97.2% and 99.9%, respectively, compared to PIS results derived from the results of broth culture for T. vaginalis and bidirectional gene sequencing of amplicons. Excellent performance characteristics were seen using both female and male specimens. The ease of using the Xpert TV assay should result in opportunities for enhanced screening for T. vaginalis in both men and women and, hopefully, improved control of this infection. PMID- 29167293 TI - Perioperative Antibiotic Prophylaxis Has No Effect on Time to Positivity and Proportion of Positive Samples: a Cohort Study of 64 Cutibacterium acnes Bone and Joint Infections. AB - If a bone or joint infection is suspected, perioperative antibiotic prophylaxis is frequently withheld until intraoperative microbiological sampling has been performed. This practice builds upon the hypothesis that perioperative antibiotics could render culture results negative and thus impede tailored antibiotic treatment of infections. We aimed to assess the influence of antibiotic prophylaxis within 30 to 60 min before surgery on time to positivity of microbiological samples and on proportion of positive samples in Cutibacterium acnes bone and joint infections. Patients with at least one sample positive for C. acnes between January 2005 and December 2015 were included and classified as having an "infection" if at least 2 samples were positive; otherwise they were considered to have a sample "contamination." Kaplan-Meier curves were used to illustrate time to culture positivity. We found 64 cases with a C. acnes infection and 46 classified as having a C. acnes contamination. Application of perioperative prophylaxis significantly differed between the infection and contamination groups (72.8% versus 55.8%; P < 0.001). Within the infection group, we found no difference in time to positivity between those who had or had not received a perioperative prophylaxis (7.07 days; 95% confidence interval [CI], 6.4 to 7.7, versus 7.11 days; 95% CI, 6.8 to 7.5; P = 0.3). Also, there was no association between the proportion of sample positivity and the application of perioperative prophylaxis (71.6% versus 65.9%; P = 0.39). Since perioperative prophylaxis did not negatively influence the microbiological yield in C. acnes infections, antibiotic prophylaxis can be routinely given to avoid surgical site infections. PMID- 29167294 TI - Verification of Ceftazidime-Avibactam and Ceftolozane-Tazobactam Susceptibility Testing Methods against Carbapenem-Resistant Enterobacteriaceae and Pseudomonas aeruginosa. AB - Ceftazidime-avibactam and ceftolozane-tazobactam are newly approved agents for the treatment of infections caused by multidrug-resistant Gram-negative bacteria. Resistance to both agents has been described clinically. Susceptibility testing on automated systems is unavailable for either agent. Our objective was to compare the disk diffusion and Etest methods to standard broth microdilution (BMD) methods for testing ceftazidime-avibactam and ceftolozane-tazobactam against a diverse collection of carbapenem-resistant Enterobacteriaceae (CRE) and carbapenem-resistant Pseudomonas aeruginosa (CRP) isolates, respectively. Among 74 ceftazidime-avibactam-susceptible and -resistant CRE isolates, BMD categorical agreement was higher with Etest (96%) than with disk diffusion (72%; P = 0.0003). Twenty-eight percent of ceftazidime-avibactam-susceptible CRE isolates were classified as resistant by disk diffusion. Results were comparable to those obtained with resistance defined genotypically. Among 72 ceftolozane-tazobactam susceptible and -resistant CRP isolates, the levels of BMD categorical agreement with disk diffusion and Etest were 94% and 96%, respectively; the only errors identified were minor. Our findings demonstrate that Etest measurements of ceftazidime-avibactam and ceftolozane-tazobactam susceptibility correlate closely with standard BMD methods, suggesting a useful role clinically. On the other hand, disk diffusion measurements overcalled CRE resistance to ceftazidime avibactam. A better understanding of ceftazidime-avibactam interpretive breakpoints is needed before disk diffusion is used routinely in the clinic. Until clinicians and microbiologists understand Etest and disk diffusion performance at their centers, test results should be interpreted cautiously. PMID- 29167296 TI - Predictors of pneumonia in lower respiratory tract infections: 3C prospective cough complication cohort study. AB - The aim was to aid diagnosis of pneumonia in those presenting with lower respiratory tract symptoms in routine primary care.A cohort of 28 883 adult patients with acute cough attributed to lower respiratory tract infections (LRTIs) was recruited from 5222 UK practices in 2009-13. Symptoms, signs and treatment were recorded at presentation and subsequent events followed-up for 30 days by chart review. The predictive value of patient characteristics, presenting symptoms and clinical findings for the diagnosis of pneumonia in the first 7 days was established.Of the 720 out of 28 883 (2.5.%) radiographed within 1 week of the index consultation, 115 (16.0%; 0.40% of 28 883) were assigned a definite or probable pneumonia diagnosis. The significant independent predictors of radiograph-confirmed pneumonia were temperature >37.8 degrees C (RR 2.6; 95% CI 1.5-4.8), crackles on auscultation (RR 1.8; 1.1-3.0), oxygen saturation <95% (RR 1.7; 1.0-3.1) and pulse >100.min-1 (RR 1.9; 1.1-3.2). Most patients with pneumonia (99/115, 86.1%) exhibited at least one of these four clinical signs; the positive predictive value of having at least one of these signs was 20.2% (95% CI 17.3-23.1).In routine practice, radiograph-confirmed pneumonia as a short term complication of LRTI is very uncommon (one in 270). Pulse oximetry may aid the diagnosis of pneumonia in this setting. PMID- 29167295 TI - Sex-specific impact of asthma during pregnancy on infant gut microbiota. AB - Asthma during pregnancy is associated with retardation of fetal growth in a sex specific manner. Lactobacilli microbes influence infant growth. This study aimed to determine whether lactobacilli and other microbes are reduced in the gut of infants born to an asthmatic mother, and whether this differs by the sex of the infant.Mother-infant pairs (N=1021) from the Canadian Healthy Infant Longitudinal Development full-term cohort were studied. The abundance of infant faecal microbiota at 3-4 months, profiled by gene sequencing, was compared between both women with and without asthma treatment during pregnancy. Infant sex, maternal ethnicity, pre-pregnancy overweight and atopy status, birth mode, breastfeeding status and intrapartum antibiotic treatment were tested as covariates.Independent of birth mode and other covariates, male, Caucasian infants born to women with prenatal asthma harboured fewer lactobacilli in the gut at 3-4 months of age. If asthmatic mothers had pre-pregnancy overweight, the abundance of Lactobacillus in males was further reduced in the infant gut, whereas the microbiota of female infants was enriched with Bacteroidaceae Similar differences in infant gut microbial composition according to maternal prenatal asthma status were also more evident among women with food or environmental allergies.Gut lactobacilli were less abundant in male infants, but Bacteroidaceae were more abundant in female infants at 3-4 months of age, following maternal asthma during pregnancy. PMID- 29167297 TI - An official European Respiratory Society statement: pulmonary haemodynamics during exercise. AB - There is growing recognition of the clinical importance of pulmonary haemodynamics during exercise, but several questions remain to be elucidated. The goal of this statement is to assess the scientific evidence in this field in order to provide a basis for future recommendations.Right heart catheterisation is the gold standard method to assess pulmonary haemodynamics at rest and during exercise. Exercise echocardiography and cardiopulmonary exercise testing represent non-invasive tools with evolving clinical applications. The term "exercise pulmonary hypertension" may be the most adequate to describe an abnormal pulmonary haemodynamic response characterised by an excessive pulmonary arterial pressure (PAP) increase in relation to flow during exercise. Exercise pulmonary hypertension may be defined as the presence of resting mean PAP <25 mmHg and mean PAP >30 mmHg during exercise with total pulmonary resistance >3 Wood units. Exercise pulmonary hypertension represents the haemodynamic appearance of early pulmonary vascular disease, left heart disease, lung disease or a combination of these conditions. Exercise pulmonary hypertension is associated with the presence of a modest elevation of resting mean PAP and requires clinical follow-up, particularly if risk factors for pulmonary hypertension are present. There is a lack of robust clinical evidence on targeted medical therapy for exercise pulmonary hypertension. PMID- 29167299 TI - Correlates and assessment of excess cardiovascular risk in bronchiectasis. AB - Patients with bronchiectasis are at increased risk of cardiovascular disease. We aimed to identify factors associated with elevated cardiovascular risk in bronchiectasis, measured using aortic stiffness and cardiac biomarkers. In addition, we sought to compare these direct measures against calculated QRISK2 scores.Aortic stiffness, cardiac biomarkers and systemic inflammation were measured in 101 adults with stable bronchiectasis. In addition, clinical and demographic data were collected to allow calculation of QRISK2 score and the bronchiectasis severity index (BSI) for each patient.The BSI score correlated with measured cardiovascular risk assessments, partly due to greater exacerbation frequency and lower forced expiratory volume in 1 s. Pulse-wave velocity was significantly higher in frequent exacerbators (>=3 events.year-1) than infrequent exacerbators (<3 events.year-1; 10.5 versus 9.2 m.s-1, p=0.01). In addition, frequent exacerbators had elevated serum C-reactive protein concentration, suggesting increased systemic inflammation (4.8 versus 2.2 mg.L-1, p=0.005). QRISK2 systematically underestimated cardiovascular risk in this population (median change in relative risk 1.29). Underestimation was associated with frequent exacerbations and male sex.Patients with bronchiectasis have greater cardiovascular risk than published reference populations. Excess cardiovascular risk is associated with exacerbation frequency and impaired lung function. Cardiovascular risk assessment in bronchiectasis should be individualised, as calculation tools are likely to underestimate the risk in this population.

AB - Previous studies have shown that opioids can reduce chronic breathlessness in advanced disease. However, physicians remain reluctant to prescribe opioids for these patients, commonly due to fear of respiratory adverse effects. The aim of this study was to systematically review reported respiratory adverse effects of opioids in patients with advanced disease and chronic breathlessness.PubMed, Embase, the Cochrane Central Register of Controlled Trials, CINAHL, ClinicalTrials.gov and the reference lists of relevant systematic reviews were searched. Two independent researchers screened against predefined inclusion criteria and extracted data. Meta-analysis was conducted where possible.We included 63 out of 1990 articles, describing 67 studies. Meta-analysis showed an increase in carbon dioxide tension (0.27 kPa, 95% CI 0.08-0.45 kPa,) and no significant change in oxygen tension and oxygen saturation (both p>0.05). Nonserious respiratory depression (definition variable/not stated) was described in four out of 1064 patients. One cancer patient pretreated with morphine for pain needed temporary respiratory support following nebulised morphine for breathlessness (single case study).We found no evidence of significant or clinically relevant respiratory adverse effects of opioids for chronic breathlessness. Heterogeneity of design and study population, and low study quality are limitations. Larger studies designed to detect respiratory adverse effects are needed.

AB - The impact of blood eosinophilia in chronic obstructive pulmonary disease (COPD) remains controversial.To evaluate the prevalence and stability of a high level of blood eosinophils (>=300 cells.MUL-1) and its relationship to outcomes, we determined blood eosinophils at baseline and over 2 years in 424 COPD patients (forced expiratory volume in 1 s (FEV1) 60% predicted) and 67 smokers without COPD from the CHAIN cohort, and in 308 COPD patients (FEV1 60% predicted) in the BODE cohort. We related eosinophil levels to exacerbations and survival using Cox hazard analysis.In COPD patients, 15.8% in the CHAIN cohort and 12.3% in the BODE cohort had persistently elevated blood eosinophils at all three visits. A significant proportion (43.8%) of patients had counts that oscillated above and below the cut-off points, while the rest had persistent eosinophil levels <300 cells.MUL-1 A similar eosinophil blood pattern was observed in controls. Exacerbation rates did not differ in patients with and without eosinophilia. All cause mortality was lower in patients with high eosinophils compared with those with values <300 cells.MUL-1 (15.8% versus 33.7%; p=0.026).In patients with COPD, blood eosinophils >=300 cells.MUL-1 persisting over 2 years was not a risk factor for COPD exacerbations. High eosinophil count was associated with better survival.

AB - We studied the prevalence, burden and potential risk factors for chronic bronchitis symptoms in the Burden of Obstructive Lung Disease study.Representative population-based samples of adults aged >=40 years were selected in participating sites. Participants completed questionnaires and spirometry. Chronic bronchitis symptoms were defined as chronic cough and phlegm on most days for >=3 months each year for >=2 years.Data from 24 855 subjects from 33 sites in 29 countries were analysed. There were significant differences in the prevalence of self-reported symptoms meeting our definition of chronic bronchitis across sites, from 10.8% in Lexington (KY, USA), to 0% in Ile-Ife (Nigeria) and Blantyre (Malawi). Older age, less education, current smoking, occupational exposure to fumes, self-reported diagnosis of asthma or lung cancer and family history of chronic lung disease were all associated with increased risk of chronic bronchitis. Chronic bronchitis symptoms were associated with worse lung function, more dyspnoea, increased risk of respiratory exacerbations and reduced quality of life, independent of the presence of other lung diseases.The prevalence of chronic bronchitis symptoms varied widely across the studied sites. Chronic bronchitis symptoms were associated with significant burden both in individuals with chronic airflow obstruction and those with normal lung function.

PMID- 29167310 TI - The first cell-fate decision of mouse preimplantation embryo development: integrating cell position and polarity. AB - During the first cell-fate decision of mouse preimplantation embryo development, a population of outer-residing polar cells is segregated from a second population of inner apolar cells to form two distinct cell lineages: the trophectoderm and the inner cell mass (ICM), respectively. Historically, two models have been proposed to explain how the initial differences between these two cell populations originate and ultimately define them as the two stated early blastocyst stage cell lineages. The 'positional' model proposes that cells acquire distinct fates based on differences in their relative position within the developing embryo, while the 'polarity' model proposes that the differences driving the lineage segregation arise as a consequence of the differential inheritance of factors, which exhibit polarized subcellular localizations, upon asymmetric cell divisions. Although these two models have traditionally been considered separately, a growing body of evidence, collected over recent years, suggests the existence of a large degree of compatibility. Accordingly, the main aim of this review is to summarize the major historical and more contemporarily identified events that define the first cell-fate decision and to place them in the context of both the originally proposed positional and polarity models, thus highlighting their functional complementarity in describing distinct aspects of the developmental programme underpinning the first cell-fate decision in mouse embryogenesis. PMID- 29167311 TI - The human CTF4-orthologue AND-1 interacts with DNA polymerase alpha/primase via its unique C-terminal HMG box. AB - A dynamic multi-protein assembly known as the replisome is responsible for DNA synthesis in eukaryotic cells. In yeast, the hub protein Ctf4 bridges DNA helicase and DNA polymerase and recruits factors with roles in metabolic processes coupled to DNA replication. An important question in DNA replication is the extent to which the molecular architecture of the replisome is conserved between yeast and higher eukaryotes. Here, we describe the biochemical basis for the interaction of the human CTF4-orthologue AND-1 with DNA polymerase alpha (Pol alpha)/primase, the replicative polymerase that initiates DNA synthesis. AND-1 has maintained the trimeric structure of yeast Ctf4, driven by its conserved SepB domain. However, the primary interaction of AND-1 with Pol alpha/primase is mediated by its C-terminal HMG box, unique to mammalian AND-1, which binds the B subunit, at the same site targeted by the SV40 T-antigen for viral replication. In addition, we report a novel DNA-binding activity in AND-1, which might promote the correct positioning of Pol alpha/primase on the lagging-strand template at the replication fork. Our findings provide a biochemical basis for the specific interaction between two critical components of the human replisome, and indicate that important principles of replisome architecture have changed significantly in evolution. PMID- 29167312 TI - Inhibition of O-GlcNAcase Sensitizes Apoptosis and Reverses Bortezomib Resistance in Mantle Cell Lymphoma through Modification of Truncated Bid. AB - Aberrant energy metabolism represents a hallmark of cancer and contributes to numerous aggressive behaviors of cancer cells, including cell death and survival. Despite the poor prognosis of mantle cell lymphoma (MCL), due to the inevitable development of drug resistance, metabolic reprograming of MCL cells remains an unexplored area. Posttranslational modification of proteins via O-GlcNAcylation is an ideal sensor for nutritional changes mediated by O-GlcNAc transferase (OGT) and is removed by O-GlcNAcase (OGA). Using various small-molecule inhibitors of OGT and OGA, we found for the first time that O-GlcNAcylation potentiates MCL response to bortezomib. CRISPR interference of MGEA5 (encoding OGA) validated the apoptosis sensitization by O-GlcNAcylation and OGA inhibition. To identify the potential clinical candidates, we tested MCL response to drug-like OGA inhibitor, ketoconazole, and verified that it exerts similar sensitizing effect on bortezomib-induced apoptosis. Investigations into the underlying molecular mechanisms reveal that bortezomib and ketoconazole act in concert to cause the accumulation of truncated Bid (tBid). Not only does ketoconazole potentiate tBid induction, but also increases tBid stability through O-GlcNAcylation that interferes with tBid ubiquitination and proteasomal degradation. Remarkably, ketoconazole strongly enhances bortezomib-induced apoptosis in de novo bortezomib resistant MCL cells and in patient-derived primary cells with minimal cytotoxic effect on normal peripheral blood mononuclear cells and hepatocytes, suggesting its potential utility as a safe and effective adjuvant for MCL. Together, our findings provide novel evidence that combination of bortezomib and ketoconazole or other OGA inhibitors may present a promising strategy for the treatment of drug-resistant MCL.

AB - The anaphase promoting complex or cyclosome (APC/C) is a large multi-subunit E3 ubiquitin ligase that orchestrates cell cycle progression by mediating the degradation of important cell cycle regulators. During the two decades since its discovery, much has been learnt concerning its role in recognizing and ubiquitinating specific proteins in a cell-cycle-dependent manner, the mechanisms governing substrate specificity, the catalytic process of assembling polyubiquitin chains on its target proteins, and its regulation by phosphorylation and the spindle assembly checkpoint. The past few years have witnessed significant progress in understanding the quantitative mechanisms underlying these varied APC/C functions. This review integrates the overall functions and properties of the APC/C with mechanistic insights gained from recent cryo-electron microscopy (cryo-EM) studies of reconstituted human APC/C complexes. PMID- 29167313 TI - Mechanism-informed Repurposing of Minocycline Overcomes Resistance to Topoisomerase Inhibition for Peritoneal Carcinomatosis. AB - Mechanism-inspired drug repurposing that augments standard treatments offers a cost-effective and rapid route toward addressing the burgeoning problem of plateauing of effective therapeutics for drug-resistant micrometastases. We show that the antibiotic minocycline, by its ability to minimize DNA repair via reduced expression of tyrosyl-DNA phosphodiesterase-1 (Tdp1), removes a key process attenuating the efficacy of irinotecan, a frequently used chemotherapeutic against metastatic disease. Moreover, minocycline and irinotecan cooperatively mitigate each other's undesired cytokine inductions of VEGF and IL8, respectively, thereby reinforcing the benefits of each modality. These mechanistic interactions result in synergistic enhancement of irinotecan-induced platinum-resistant epithelial ovarian cancer cell death, reduced micrometastases in the omenta and mesentery by >75%, and an extended overall survival by 50% in a late-stage peritoneal carcinomatosis mouse model. Economic incentives and easy translatability make the repurposing of minocycline as a reinforcer of the topoisomerase class of chemotherapeutics extremely valuable and merits further investigations.

AB - One of the most encouraging developments in oncology has been the success of BRAF inhibitors in BRAF-mutant melanoma. However, in contrast to its striking efficacy in BRAF-mutant melanomas, BRAF inhibitor monotherapy is ineffective in BRAF mutant colorectal cancer. Although many studies on BRAF inhibitor resistance in colorectal cancer have focused on mechanisms underlying the reactivation of the EGFR/RAS/RAF/MEK/ERK pathway, the current study focuses on identifying novel adaptive signaling mechanisms, a fresh angle on colorectal cancer resistance to BRAF inhibition. We found that treatment with BRAF inhibitors (both current and next-generation BRAF inhibitors) upregulated the Wnt/beta-catenin pathway in BRAFV600E-mutant colorectal cancer cell lines through activating the cytoplasmic tyrosine kinase focal adhesion kinase (FAK). The results showed that FAK activation upon BRAF inhibitor treatment did not require EGFR or ERK1/2 activation, implying that BRAF inhibitor treatment-induced hyperactivation of Wnt signaling is "pathway reactivation"-independent. BRAF inhibition-induced Wnt pathway activation was further validated in preclinical models of BRAFV600E mutant colorectal cancer, including cell line xenograft model and a patient derived xenograft model. Combined inhibition of BRAF/Wnt pathways or BRAF/FAK pathways exerted strong synergistic antitumor effects in cell culture model and mouse xenograft model. Overall, the current study has identified activation of the Wnt/beta-catenin pathway as a novel fundamental cause of colon cancer resistance to BRAF inhibition. Our results suggest that although complete vertical pathway blockade is pivotal for effective and durable control of BRAF mutant colorectal cancer, cotargeting parallel adaptive signaling-the Wnt/beta catenin pathway-is also essential.

PMID- 29167315 TI - A Novel YAP1 Inhibitor Targets CSC-Enriched Radiation-Resistant Cells and Exerts Strong Antitumor Activity in Esophageal Adenocarcinoma. AB - Mounting evidence suggests that the Hippo coactivator Yes-associated protein 1 (YAP1) is a major mediator of cancer stem cell (CSC) properties, tumor progression, and therapy resistance as well as often a terminal node of many oncogenic pathways. Thus, targeting YAP1 may be a novel therapeutic strategy for many types of tumors with high YAP1 expression, including esophageal adenocarcinoma. However, effective YAP1 inhibitors are currently lacking. Here, we identify a small molecule (CA3) that not only has remarkable inhibitory activity on YAP1/Tead transcriptional activity but also demonstrates strong inhibitory effects on esophageal adenocarcinoma cell growth especially on YAP1 high-expressing esophageal adenocarcinoma cells both in vitro and in vivo Remarkably, radiation-resistant cells acquire strong cancer stem cell (CSC) properties and aggressive phenotype, while CA3 can effectively suppress these phenotypes by inhibiting proliferation, inducing apoptosis, reducing tumor sphere formation, and reducing the fraction of ALDH1+ cells. Furthermore, CA3, combined with 5-FU, synergistically inhibits esophageal adenocarcinoma cell growth especially in YAP1 high esophageal adenocarcinoma cells. Taken together, these findings demonstrated that CA3 represents a new inhibitor of YAP1 and primarily targets YAP1 high and therapy-resistant esophageal adenocarcinoma cells endowed with CSC properties.

AB - Recent studies suggest that a circulating protein called TRAIL (TNF-related apoptosis inducing ligand) may have an important role in the treatment of type 2 diabetes. It has been shown that TRAIL deficiency worsens diabetes and that TRAIL delivery, when it is given before disease onset, slows down its development. The present study aimed at evaluating whether TRAIL had the potential not only to prevent, but also to treat type 2 diabetes. Thirty male C57BL/6J mice were randomized to a standard or a high-fat diet (HFD). After 4 weeks of HFD, mice were further randomized to receive either placebo or TRAIL, which was delivered weekly for 8 weeks. Body weight, food intake, fasting glucose, and insulin were measured at baseline and every 4 weeks. Tolerance tests were performed before drug randomization and at the end of the study. Tissues were collected for further analyses. Parallel in vitro studies were conducted on HepG2 cells and mouse primary hepatocytes. TRAIL significantly reduced body weight, adipocyte hypertrophy, free fatty acid levels, and inflammation. Moreover, it significantly improved impaired glucose tolerance, and ameliorated non-alcoholic fatty liver disease (NAFLD). TRAIL treatment reduced liver fat content by 47% in vivo as well as by 45% in HepG2 cells and by 39% in primary hepatocytes. This was associated with a significant increase in liver peroxisome proliferator-activated receptor (PPAR) gamma (PPARgamma) co-activator-1 alpha (PGC-1alpha) expression both in vivo and in vitro, pointing to a direct protective effect of TRAIL on the liver. The present study confirms the ability of TRAIL to significantly attenuate diet induced metabolic abnormalities, and it shows for the first time that TRAIL is effective also when administered after disease onset. In addition, our data shed light on TRAIL therapeutic potential not only against impaired glucose tolerance, but also against NAFLD.

PMID- 29167317 TI - Rodent vertical sleeve gastrectomy alters maternal immune health and fetoplacental development. AB - Bariatric surgery is increasingly employed to improve fertility and reduce obesity-related co-morbidities in obese women. Surgical weight loss not only improves the chance of conception but reduces the risk of pregnancy complications including pre-eclampsia, gestational diabetes, and macrosomia. However, bariatric procedures increase the incidence of intrauterine growth restriction (IUGR), fetal demise, thromboembolism, and other gestational disorders. Using our rodent model of vertical sleeve gastrectomy (VSG), we tested the hypothesis that VSG in diet-induced, obese dams would cause immune and placental structural abnormalities that may be responsible for fetal demise during pregnancy. VSG dams studied on gestational day (G) 19 had reduced circulating T-cell (CD3+ and CD8+) populations compared with lean or obese controls. Further, local interleukin (IL) 1beta and IL 1 receptor antagonist (il1rn) cmRNA were increased in placenta of VSG dams. Placental barrier function was also affected, with increased transplacental permeability to small molecules, increased matrix metalloproteinase 9 expression, and increased apoptosis in VSG. Furthermore, we identified increased placental mTOR signaling that may contribute to preserving the body weight of the fetuses during gestation. These changes occurred in the absence of a macronutrient deficit or gestational hypertension in the VSG dams. In summary, previous VSG in dams may contribute to fetal demise by affecting maternal immune system activity and compromise placental integrity. PMID- 29167316 TI - Quantitative Phosphoproteomic Analysis Reveals Shared and Specific Targets of Arabidopsis Mitogen-Activated Protein Kinases (MAPKs) MPK3, MPK4, and MPK6. AB - In Arabidopsis, mitogen-activated protein kinases MPK3, MPK4, and MPK6 constitute essential relays for a variety of functions including cell division, development and innate immunity. Although some substrates of MPK3, MPK4 and MPK6 have been identified, the picture is still far from complete. To identify substrates of these MAPKs likely involved in cell division, growth and development we compared the phosphoproteomes of wild-type and mpk3, mpk4, and mpk6. To study the function of these MAPKs in innate immunity, we analyzed their phosphoproteomes following microbe-associated molecular pattern (MAMP) treatment. Partially overlapping substrates were retrieved for all three MAPKs, showing target specificity to one, two or all three MAPKs in different biological processes. More precisely, our results illustrate the fact that the entity to be defined as a specific or a shared substrate for MAPKs is not a phosphoprotein but a particular (S/T)P phosphorylation site in a given protein. One hundred fifty-two peptides were identified to be differentially phosphorylated in response to MAMP treatment and/or when compared between genotypes and 70 of them could be classified as putative MAPK targets. Biochemical analysis of a number of putative MAPK substrates by phosphorylation and interaction assays confirmed the global phosphoproteome approach. Our study also expands the set of MAPK substrates to involve other protein kinases, including calcium-dependent (CDPK) and sugar nonfermenting (SnRK) protein kinases. PMID- 29167320 TI - MAPKs Influence Pollen Tube Growth by Controlling the Formation of Phosphatidylinositol 4,5-Bisphosphate in an Apical Plasma Membrane Domain. AB - An apical plasma membrane domain enriched in the regulatory phospholipid phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2] is critical for polar tip growth of pollen tubes. How the biosynthesis of PtdIns(4,5)P2 by phosphatidylinositol 4-phosphate 5-kinases (PI4P 5-kinases) is controlled by upstream signaling is currently unknown. The pollen-expressed PI4P 5-kinase PIP5K6 is required for clathrin-mediated endocytosis and polar tip growth in pollen tubes. Here, we identify PIP5K6 as a target of the pollen-expressed mitogen-activated protein kinase MPK6 and characterize the regulatory effects. Based on an untargeted mass spectrometry approach, phosphorylation of purified recombinant PIP5K6 by pollen tube extracts could be attributed to MPK6. Recombinant MPK6 phosphorylated residues T590 and T597 in the variable insert of the catalytic domain of PIP5K6, and this modification inhibited PIP5K6 activity in vitro. PIP5K6 interacted with MPK6 in yeast two-hybrid tests, immuno-pull-down assays, and by bimolecular fluorescence complementation at the apical plasma membrane of pollen tubes. In vivo, MPK6 expression resulted in reduced plasma membrane association of a fluorescent PtdIns(4,5)P2 reporter and decreased endocytosis without impairing membrane association of PIP5K6. Effects of PIP5K6 expression on pollen tube growth and cell morphology were attenuated by coexpression of MPK6 in a phosphosite-dependent manner. Our data indicate that MPK6 controls PtdIns(4,5)P2 production and membrane trafficking in pollen tubes, possibly contributing to directional growth.

PMID- 29167321 TI - An Automated Confocal Micro-Extensometer Enables in Vivo Quantification of Mechanical Properties with Cellular Resolution. AB - How complex developmental-genetic networks are translated into organs with specific 3D shapes remains an open question. This question is particularly challenging because the elaboration of specific shapes is in essence a question of mechanics. In plants, this means how the genetic circuitry affects the cell wall. The mechanical properties of the wall and their spatial variation are the key factors controlling morphogenesis in plants. However, these properties are difficult to measure and investigating their relation to genetic regulation is particularly challenging. To measure spatial variation of mechanical properties, one must determine the deformation of a tissue in response to a known force with cellular resolution. Here, we present an automated confocal micro-extensometer (ACME), which greatly expands the scope of existing methods for measuring mechanical properties. Unlike classical extensometers, ACME is mounted on a confocal microscope and uses confocal images to compute the deformation of the tissue directly from biological markers, thus providing 3D cellular scale information and improved accuracy. Additionally, ACME is suitable for measuring the mechanical responses in live tissue. As a proof of concept, we demonstrate that the plant hormone gibberellic acid induces a spatial gradient in mechanical properties along the length of the Arabidopsis thaliana hypocotyl. PMID- 29167323 TI - Prefrontal cortical-specific differences in behavior and synaptic plasticity between adolescent and adult mice. AB - Adolescence is a highly vulnerable period for the emergence of major neuropsychological disorders and is characterized by decreased cognitive control and increased risk-taking behavior and novelty-seeking. The prefrontal cortex (PFC) is involved in the cognitive control of impulsive and risky behavior. Although the PFC is known to reach maturation later than other cortical areas, little information is available regarding the functional changes from adolescence to adulthood in PFC, particularly compared with other primary cortical areas. This study aims to understand the development of PFC-mediated, compared with non PFC-mediated, cognitive functions. Toward this aim, we performed cognitive behavioral tasks in adolescent and adult mice and subsequently investigated synaptic plasticity in two different cortical areas. Our results showed that adolescent mice exhibit impaired performance in PFC-dependent cognitive tasks compared with adult mice, whereas their performance in non-PFC-dependent tasks is similar to that of adults. Furthermore, adolescent mice exhibited decreased long term potentiation (LTP) within upper-layer synapses of the PFC but not the barrel cortex. Blocking GABAA receptor function significantly augments LTP in both the adolescent and adult PFC. No change in intrinsic excitability of PFC pyramidal neurons was observed between adolescent and adult mice. Finally, increased expression of the NR2A subunit of the N-methyl-d-aspartate receptors is found only in the adult PFC, a change that could underlie the emergence of LTP. In conclusion, our results demonstrate physiological and behavioral changes during adolescence that are specific to the PFC and could underlie the reduced cognitive control in adolescents. NEW & NOTEWORTHY This study reports that adolescent mice exhibit impaired performance in cognitive functions dependent on the prefrontal cortex but not in cognitive functions dependent on other cortical regions. The current results propose reduced synaptic plasticity in the upper layers of the prefrontal cortex as a cellular correlate of this weakened cognitive function. This decreased synaptic plasticity is due to reduced N-methyl-d-aspartate receptor expression but not due to dampened intrinsic excitability or enhanced GABAergic signaling during adolescence. PMID- 29167324 TI - Impact of spatiotemporal calcium dynamics within presynaptic active zones on synaptic delay at the frog neuromuscular junction. AB - The spatiotemporal calcium dynamics within presynaptic neurotransmitter release sites (active zones, AZs) at the time of synaptic vesicle fusion is critical for shaping the dynamics of neurotransmitter release. Specifically, the relative arrangement and density of voltage-gated calcium channels (VGCCs) as well as the concentration of calcium buffering proteins can play a large role in the timing, magnitude, and plasticity of release by shaping the AZ calcium profile. However, a high-resolution understanding of the role of AZ structure in spatiotemporal calcium dynamics and how it may contribute to functional heterogeneity at an adult synapse is currently lacking. We demonstrate that synaptic delay varies considerably across, but not within, individual synapses at the frog neuromuscular junction (NMJ). To determine how elements of the AZ could contribute to this variability, we performed a parameter search using a spatially realistic diffusion reaction-based computational model of a frog NMJ AZ (Dittrich M, Pattillo JM, King JD, Cho S, Stiles JR, Meriney SD. Biophys J 104: 2751-2763, 2013; Ma J, Kelly L, Ingram J, Price TJ, Meriney SD, Dittrich M. J Neurophysiol 113: 71-87, 2015). We demonstrate with our model that synaptic delay is sensitive to significant alterations in the spatiotemporal calcium dynamics within an AZ at the time of release caused by manipulations of the density and organization of VGCCs or by the concentration of calcium buffering proteins. Furthermore, our data provide a framework for understanding how AZ organization and structure are important for understanding presynaptic function and plasticity. NEW & NOTEWORTHY The structure of presynaptic active zones (AZs) can play a large role in determining the dynamics of neurotransmitter release across many model preparations by influencing the spatiotemporal calcium dynamics within the AZ at the time of vesicle fusion. However, less is known about how different AZ structural schemes may influence the timing of neurotransmitter release. We demonstrate that variations in AZ structure create different spatiotemporal calcium profiles that, in turn, lead to differences in synaptic delay. PMID- 29167325 TI - The modulation of hippocampal theta rhythm by the vestibular system. AB - The vestibular system is a sensory system that has evolved over millions of years to detect acceleration of the head, both rotational and translational, in three dimensions. One of its most important functions is to stabilize gaze during unexpected head movement; however, it is also important in the control of posture and autonomic reflexes. Theta rhythm is a 3- to 12-Hz oscillating EEG signal that is intimately linked to self-motion and is also known to be important in learning and memory. Many studies over the last two decades have shown that selective activation of the vestibular system, using either natural rotational or translational stimulation, or electrical stimulation of the peripheral vestibular system, can induce and modulate theta activity. Furthermore, inactivation of the vestibular system has been shown to significantly reduce theta in freely moving animals, which may be linked to its impairment of place cell function as well as spatial learning and memory. The pathways through which vestibular information modulate theta rhythm remain debatable. However, vestibular responses have been found in the pedunculopontine tegmental nucleus (PPTg) and activation of the vestibular system causes an increase in acetylcholine release into the hippocampus, probably from the medial septum. Therefore, a pathway from the vestibular nucleus complex and/or cerebellum to the PPTg, supramammillary nucleus, posterior hypothalamic nucleus, and septum to the hippocampus is likely. The modulation of theta by the vestibular system may have implications for vestibular effects on cognitive function and the contribution of vestibular impairment to the risk of dementia. PMID- 29167326 TI - Tactile perception of the roughness of 3D-printed textures. AB - Surface roughness is one of the most important qualities in haptic perception. Roughness is a major identifier for judgments of material composition, comfort, and friction and is tied closely to manual dexterity. Some attention has been given to the study of roughness perception in the past, but it has typically focused on noncontrollable natural materials or on a narrow range of artificial materials. The advent of high-resolution three-dimensional (3D) printing technology provides the ability to fabricate arbitrary 3D textures with precise surface geometry to be used in tactile studies. We used parametric modeling and 3D printing to manufacture a set of textured plates with defined element spacing, shape, and arrangement. Using active touch and two-alternative forced-choice protocols, we investigated the contributions of these surface parameters to roughness perception in human subjects. Results indicate that large spatial periods produce higher estimations of roughness (with Weber fraction = 0.19), small texture elements are perceived as rougher than large texture elements of the same wavelength, perceptual differences exist between textures with the same spacing but different arrangements, and roughness equivalencies exist between textures differing along different parameters. We posit that papillary ridges serve as tactile processing units, and neural ensembles encode the spatial profiles of the texture contact area to produce roughness estimates. The stimuli and the manufacturing process may be used in further studies of tactile roughness perception and in related neurophysiological applications. NEW & NOTEWORTHY Surface roughness is an integral quality of texture perception. We manufactured textures using high-resolution 3D printing, which allows precise specification of the surface spatial topography. In human psychophysical experiments we investigated the contributions of specific surface parameters to roughness perception. We found that textures with large spatial periods, small texture elements, and irregular, isotropic arrangements elicit the highest estimations of roughness. We propose that roughness correlates inversely with the total contacted surface area. PMID- 29167327 TI - Learning-induced modulation of the effect of endocannabinoids on inhibitory synaptic transmission. AB - are key modulators that regulate central brain functions and behaviors, including learning and memory. At the cellular and molecular levels, endocannabinoids are potent modulators of excitatory and inhibitory synaptic function. Most effects of cannabinoids are thought to be mediated via G protein-coupled cannabinoid receptors. In particular, cannabinoids released from postsynaptic neurons are suggested to act as retrograde messengers, activating presynaptic type-1 cannabinoid receptors (CB1Rs), thereby inducing suppression of synaptic release. Another central mechanism of cannabinoid-induced action requires activation of astroglial CB1Rs. CB1Rs are also implicated in self-modulation of cortical neurons. Rats that are trained in a particularly difficult olfactory discrimination task show a dramatic increased ability to acquire memories of new odors. The memory of the acquired high-skill acquisition, termed "rule learning" or "learning set," lasts for many months. Using this behavioral paradigm, we show a novel function of action for CB1Rs, supporting long-term memory by maintaining persistent enhancement of inhibitory synaptic transmission. Long-lasting enhancement of inhibitory synaptic transmission is blocked by a CB1R inverse agonist. This effect is mediated by a novel purely postsynaptic mechanism, obtained by enhancing the single GABAA channel conductance that is PKA dependent. The significant role that CB1R has in maintaining learning-induced long-term strengthening of synaptic inhibition suggests that endocannabinoids have a key role in maintaining long-term memory by enhancing synaptic inhibition. NEW & NOTEWORTHY In this study we show a novel function and mechanism of action for cannabinoids in neurons, mediated by activation of type-1 cannabinoid receptors, supporting long-term memory by maintaining persistent enhancement of inhibitory synaptic transmission on excitatory neurons. This effect is mediated by a novel purely postsynaptic mechanism, obtained by enhancing the single GABAA channel conductance that is PKA dependent. Thus we report for the first time that endocannabinoids have a key role maintaining learning-induced synaptic modification. PMID- 29167328 TI - Perceptual decisions based on previously learned information are independent of dopaminergic tone. AB - Both cognitive and motor symptoms in people with Parkinson's disease (PD) arise from either too little or too much dopamine (DA). Akinesia stems from DA neuronal cell loss, and dyskinesia often stems from an overdose of DA medication. Cognitive behaviors typically associated with frontal cortical function, such as working memory and task switching, are also affected by too little or too much DA in PD. Whether motor and cognitive circuits overlap in PD is unknown. In this article, we show that whereas motor performance improves in people with PD when on dopaminergic medication compared with off medication, perceptual decision making based on previously learned information (priors) remains impaired whether on or off medications. To rule out effects of long-term DA treatment and dopaminergic neuronal loss such as occur in PD, we also tested a group of people with dopa-unresponsive focal dystonia, a disease that involves the basal ganglia, like PD, but has motor symptoms that are insensitive to dopamine treatment and is not thought to involve frontal cortical DA circuits, unlike PD. We found that people with focal dystonia showed intact perceptual decision-making performance but impaired use of priors in perceptual decision-making, similar to people with PD. Together, the results show a dissociation between motor and cognitive performance in people with PD and reveal a novel cognitive impairment, independent of sensory and motor impairment, in people with focal dystonia. The combined results from people with PD and people with focal dystonia provide mechanistic insights into the role of basal ganglia non-dopaminergic circuits in perceptual decision-making based on priors.

AB - Visual impairment intracranial pressure (VIIP) syndrome is considered an unexplained major risk for future long-duration spaceflight. NASA recently redefined this syndrome as Spaceflight-Associated Neuro-ocular Syndrome (SANS). Evidence thus reviewed supports that chronic, mildly elevated intracranial pressure (ICP) in space (as opposed to more variable ICP with posture and activity on Earth) is largely accounted for by loss of hydrostatic pressures and altered hemodynamics in the intracranial circulation and the cerebrospinal fluid system. In space, an elevated pressure gradient across the lamina cribrosa, caused by a chronic but mildly elevated ICP, likely elicits adaptations of multiple structures and fluid systems in the eye which manifest themselves as the VIIP syndrome. A chronic mismatch between ICP and intraocular pressure (IOP) in space may acclimate the optic nerve head, lamina cribrosa, and optic nerve subarachnoid space to a condition that is maladaptive to Earth, all contributing to the pathogenesis of space VIIP syndrome. Relevant findings help to evaluate whether artificial gravity is an appropriate countermeasure to prevent this seemingly adverse effect of long-duration spaceflight. PMID- 29167332 TI - Redox Regulation of Homeostasis and Proteostasis in Peroxisomes. AB - Peroxisomes are highly dynamic intracellular organelles involved in a variety of metabolic functions essential for the metabolism of long-chain fatty acids, d amino acids, and many polyamines. A byproduct of peroxisomal metabolism is the generation, and subsequent detoxification, of reactive oxygen and nitrogen species, particularly hydrogen peroxide (H2O2). Because of its relatively low reactivity (as a mild oxidant), H2O2 has a comparatively long intracellular half life and a high diffusion rate, all of which makes H2O2 an efficient signaling molecule. Peroxisomes also have intricate connections to mitochondria, and both organelles appear to play important roles in regulating redox signaling pathways. Peroxisomal proteins are also subject to oxidative modification and inactivation by the reactive oxygen and nitrogen species they generate, but the peroxisomal LonP2 protease can selectively remove such oxidatively damaged proteins, thus prolonging the useful lifespan of the organelle. Peroxisomal homeostasis must adapt to the metabolic state of the cell, by a combination of peroxisome proliferation, the removal of excess or badly damaged organelles by autophagy (pexophagy), as well as by processes of peroxisome inheritance and motility. More recently the tumor suppressors ataxia telangiectasia mutate (ATM) and tuberous sclerosis complex (TSC), which regulate mTORC1 signaling, have been found to regulate pexophagy in response to variable levels of certain reactive oxygen and nitrogen species. It is now clear that any significant loss of peroxisome homeostasis can have devastating physiological consequences. Peroxisome dysregulation has been implicated in several metabolic diseases, and increasing evidence highlights the important role of diminished peroxisomal functions in aging processes. PMID- 29167333 TI - Authentic Patient-Derived Hepatitis C Virus Infects and Productively Replicates in Primary CD4+ and CD8+ T Lymphocytes In Vitro. AB - Accumulated evidence indicates that immune cells can support the replication of hepatitis C virus (HCV) in infected patients and in culture. However, there is a scarcity of data on the degree to which individual immune cell types support HCV propagation and on characteristics of virus assembly. We investigated the ability of authentic, patient-derived HCV to infect in vitro two closely related but functionally distinct immune cell types, CD4+ and CD8+ T lymphocytes, and assessed the properties of the virus produced by these cells. The HCV replication system in intermittently mitogen-stimulated T cells was adapted to infect primary human CD4+ or CD8+ T lymphocytes. HCV replicated in both cell types although at significantly higher levels in CD4+ than in CD8+ T cells. Thus, the HCV RNA replicative (negative) strand was detected in CD4+ and CD8+ cells at estimated mean levels +/- standard errors of the means of 6.7 * 102 +/- 3.8 * 102 and 1.2 * 102 +/- 0.8 * 102 copies/MUg RNA, respectively (P < 0.0001). Intracellular HCV NS5a and/or core proteins were identified in 0.9% of CD4+ and in 1.2% of CD8+ T cells. Double staining for NS5a and T cell type-specific markers confirmed that transcriptionally competent virus replicated in both cell types. Furthermore, an HCV-specific protease inhibitor, telaprevir, inhibited infection in both CD4+ and CD8+ cells. The emergence of unique HCV variants and the release of HCV RNA reactive particles with biophysical properties different from those of virions in plasma inocula suggested that distinct viral particles were assembled, and therefore, they may contribute to the pool of circulating virus in infected patients.IMPORTANCE Although the liver is the main site of HCV replication, infection of the immune system is an intrinsic characteristic of this virus independent of whether infection is symptomatic or clinically silent. Many fundamental aspects of HCV lymphotropism remain uncertain, including the degree to which different immune cells support infection and contribute to virus diversity. We show that authentic, patient-derived HCV productively replicates in vitro in two closely related but functionally distinct types of T lymphocytes, CD4+ and CD8+ cells. The display of viral proteins and unique variants, the production of virions with biophysical properties distinct from those in plasma serving as inocula, and inhibition of replication by an antiviral agent led us to ascertain that both T cell subtypes supported virus propagation. Infection of CD4+ and CD8+ T cells, which are central to adaptive antiviral immune responses, can directly affect HCV clearance, favor virus persistence, and decisively influence the development and progression of hepatitis C. PMID- 29167334 TI - Flow Virometry: a Powerful Tool To Functionally Characterize Viruses. AB - For several decades, flow cytometry has been a common approach to analyze cells and sort them to near-purity. It enables one to probe inner cellular molecules, surface receptors, or infected cells. However, the analysis of smaller entities such as viruses and exocytic vesicles has been more difficult but is becoming mainstream. This has in part been due to the development of new instrumentation with resolutions below that of conventional cytometers. It is also attributed to the several means employed to fluorescently label viruses, hence enabling them to stand out from similarly sized particles representing background noise. Thus far, more than a dozen different viruses ranging in size from 40 nm to giant viruses have been probed by this approach, which was recently dubbed "flow virometry." These studies have collectively highlighted the breadth of the applications of this method, which, for example, has elucidated the maturation of dengue virus, served as quality control for vaccinia vaccines, and enabled the sorting of herpes simplex virus discrete viral particles. The present review focuses on the means employed to characterize and sort viruses by this powerful technology and on the emerging uses of flow virometry. It similarly addresses some of its current challenges and limitations. PMID- 29167335 TI - beta-D-N(4)-hydroxycytidine is a potent anti-alphavirus compound that induces high level of mutations in viral genome. AB - Venezuelan equine encephalitis virus (VEEV) is a representative member of the New World alphaviruses. It is transmitted by mosquito vectors and causes highly debilitating disease in humans, equides and other vertebrate hosts. Despite a continuous public health threat, very few compounds with anti-VEEV activity in cell culture and in mouse models have been identified to date, and rapid development of virus resistance to some of them has been recorded. In this study, we investigated the possibility of using a modified nucleoside analog, beta-D N(4)-hydroxycytidine (NHC), as an anti-VEEV agent and defined the mechanism of its anti-VEEV activity. The results demonstrate that NHC is a very potent antiviral agent. It affects both the release of genome RNA-containing VEE virions and their infectivity. Both these antiviral activities are determined by the NHC induced accumulation of mutations in virus-specific RNAs. The antiviral effect is most prominent when NHC is applied early in the infectious process, during amplification of negative and positive strand RNAs in the infected cells. Most importantly, only a low level resistance of VEEV to NHC can be developed, and it requires acquisition and cooperative function of more than one mutation in nsP4. These adaptive mutations are closely located in the same segment of nsP4. Our data suggest that NHC is more potent than ribavirin as an anti-VEEV agent, and likely can be used to treat other alphavirus infections.IMPORTANCEVenezuelan equine encephalitis virus (VEEV) can cause widespread epidemics among humans and domestic animals. VEEV infections result in severe meningoencephalitis and long term sequilae. No approved therapeutics exist for treatment of VEEV infections. Our study demonstrates that N-hydroxycytidine (NHC) is a very potent anti-VEEV compound, with the EC50 being below 1 MUM. The mechanism of NHC antiviral activity is based on induction of high mutation rates in the viral genome. Accordingly, NHC treatment affects both the rates of particle release and the particle infectivity. Most importantly, in contrast to most of the anti alphavirus drugs that are under development, resistance of VEEV to NHC develops very inefficiently. Even low levels of resistance require acquisition of multiple mutations in the gene of VEEV-specific RNA-dependent RNA polymerase, nsP4. PMID- 29167336 TI - Insight into the Roles of E3 Ubiquitin Ligase c-Cbl, ESCRT Machinery, and Host Cell Signaling in Kaposi's Sarcoma-Associated Herpesvirus Entry and Trafficking. AB - Kaposi's sarcoma-associated herpesvirus (KSHV) in vitro infection of dermal endothelial cells begins with its binding to host cell surface receptor molecules such as heparan sulfate (HS), integrins (alpha3beta1, alphaVbeta3, and alphaVbeta5), xCT, and EphA2 receptor tyrosine kinase (EphA2R). These initial events initiate dynamic host protein-protein interactions involving a multimolecular complex of receptors, signal molecules (focal adhesion kinase [FAK], Src, phosphatidylinositol 3-kinase [PI3-K], and RhoA-GTPase), adaptors (c Cbl, CIB1, Crk, p130Cas, and GEF-C3G), actin, and myosin II light chain that lead to virus entry via macropinocytosis. Here we discuss how KSHV hijacks c-Cbl, an E3 ubiquitin ligase, to monoubiquitinate the receptors and actin, which acts like a marker for trafficking (similar to zip codes), resulting in the recruitment of the members of the host endosomal sorting complexes required for transport (ESCRT) Hrs, Tsg101, EAP45, and the CHMP5 and -6 proteins (zip code readers) recognizing the ubiquitinated protein and adaptor machinery to traffic through the different endosomal compartments in the cytoplasm to initiate the macropinocytic process and infection. PMID- 29167337 TI - Differential Immunodominance Hierarchy of CD8+ T-Cell Responses in HLA-B*27:05- and -B*27:02-Mediated Control of HIV-1 Infection. AB - The well-characterized association between HLA-B*27:05 and protection against HIV disease progression has been linked to immunodominant HLA-B*27:05-restricted CD8+ T-cell responses toward the conserved Gag KK10 (residues 263 to 272) and polymerase (Pol) KY9 (residues 901 to 909) epitopes. We studied the impact of the 3 amino acid differences between HLA-B*27:05 and the closely related HLA-B*27:02 on the HIV-specific CD8+ T-cell response hierarchy and on immune control of HIV. Genetic epidemiological data indicate that both HLA-B*27:02 and HLA-B*27:05 are associated with slower disease progression and lower viral loads. The effect of HLA-B*27:02 appeared to be consistently stronger than that of HLA-B*27:05. In contrast to HLA-B*27:05, the immunodominant HIV-specific HLA-B*27:02-restricted CD8+ T-cell response is to a Nef epitope (residues 142 to 150 [VW9]), with Pol KY9 subdominant and Gag KK10 further subdominant. This selection was driven by structural differences in the F pocket, mediated by a polymorphism between these two HLA alleles at position 81. Analysis of autologous virus sequences showed that in HLA-B*27:02-positive subjects, all three of these CD8+ T-cell responses impose selection pressure on the virus, whereas in HLA-B*27:05-positive subjects, there is no Nef VW9-mediated selection pressure. These studies demonstrate that HLA-B*27:02 mediates protection against HIV disease progression that is at least as strong as or stronger than that mediated by HLA-B*27:05. In combination with the protective Gag KK10 and Pol KY9 CD8+ T-cell responses that dominate HIV specific CD8+ T-cell activity in HLA-B*27:05-positive subjects, a Nef VW9 specific response is additionally present and immunodominant in HLA-B*27:02 positive subjects, mediated through a polymorphism at residue 81 in the F pocket, that contributes to selection pressure against HIV.IMPORTANCE CD8+ T cells play a central role in successful control of HIV infection and have the potential also to mediate the eradication of viral reservoirs of infection. The principal means by which protective HLA class I molecules, such as HLA-B*27:05 and HLA-B*57:01, slow HIV disease progression is believed to be via the particular HIV-specific CD8+ T cell responses restricted by those alleles. We focus here on HLA-B*27:05, one of the best-characterized protective HLA molecules, and the closely related HLA-B*27:02, which differs by only 3 amino acids and which has not been well studied in relation to control of HIV infection. We show that HLA-B*27:02 is also protective against HIV disease progression, but the CD8+ T-cell immunodominance hierarchy of HLA-B*27:02 differs strikingly from that of HLA-B*27:05. These findings indicate that the immunodominant HLA-B*27:02-restricted Nef response adds to protection mediated by the Gag and Pol specificities that dominate anti HIV CD8+ T-cell activity in HLA-B*27:05-positive subjects. PMID- 29167339 TI - Identification and Functional Characterization of Phosphorylation Sites of the Human Papillomavirus 31 E8^E2 Protein. AB - The papillomavirus E2 protein regulates transcription, replication, and nuclear retention of viral genomes. Phosphorylation of E2 in the hinge region has been suggested to modulate protein stability, DNA-binding activity, and chromosomal attachment. The papillomavirus E8^E2 protein shares the hinge domain with E2 and acts as a repressor of viral replication. Mass spectrometry analyses of human papillomavirus 31 (HPV31) E8^E2 and E2 proteins identify phosphorylated S78, S81, and S100 in E8^E2 and S266 and S269 in E2 in their hinge regions. Phos-tag analyses of wild-type and mutant proteins indicate that S78 is a major phosphorylation site in E8^E2, but the corresponding S266 in E2 is not. Phosphorylation at S78 regulates E8^E2's repression activity of reporter constructs, whereas the corresponding E2 mutants do not display a phenotype. Phosphorylation at S78 does not alter E8^E2's protein stability, nuclear localization, or binding to DNA or to cellular NCoR/SMRT complexes. Surprisingly, in the context of HPV31 genomes, mutation of E8^E2 S78 does not modulate viral replication or transcription in undifferentiated or differentiated cells. However, comparative transcriptome analyses of differentiated HPV31 E8^E2 S78A and S78E cell lines reveal that the expression of a small number of cellular genes is changed. Validation experiments suggest that the transcription of the cellular LYPD2 gene is altered in a phospho-S78 E8^E2-dependent manner. In summary, our data suggest that phosphorylation of S78 in E8^E2 regulates its repression activity by a novel mechanism, and this seems to be important for the modulation of host cell gene expression but not viral replication.IMPORTANCE Posttranslational modification of viral proteins is a common feature to modulate their activities. Phosphorylation of serine residues S298 and S301 in the hinge region of the bovine papillomavirus type 1 E2 protein has been shown to restrict viral replication. The papillomavirus E8^E2 protein shares the hinge domain with E2 and acts as a repressor of viral replication. A large fraction of HPV31 E8^E2 is phosphorylated at S78 in the hinge region, and this is important for E8^E2's repression activity. Surprisingly, phosphorylation at S78 in E8^E2 has no impact on viral replication in tissue culture but rather seems to modulate the expression of a small number of cellular genes. This may indicate that phosphorylation of viral transcription factors serves to broaden their target gene specificity. PMID- 29167338 TI - Inhibition of Cytosolic Phospholipase A2alpha Impairs an Early Step of Coronavirus Replication in Cell Culture. AB - Coronavirus replication is associated with intracellular membrane rearrangements in infected cells, resulting in the formation of double-membrane vesicles (DMVs) and other membranous structures that are referred to as replicative organelles (ROs). The latter provide a structural scaffold for viral replication/transcription complexes (RTCs) and help to sequester RTC components from recognition by cellular factors involved in antiviral host responses. There is increasing evidence that plus-strand RNA (+RNA) virus replication, including RO formation and virion morphogenesis, affects cellular lipid metabolism and critically depends on enzymes involved in lipid synthesis and processing. Here, we investigated the role of cytosolic phospholipase A2alpha (cPLA2alpha) in coronavirus replication using a low-molecular-weight nonpeptidic inhibitor, pyrrolidine-2 (Py-2). The inhibition of cPLA2alpha activity, which produces lysophospholipids (LPLs) by cleaving at the sn-2 position of phospholipids, had profound effects on viral RNA and protein accumulation in human coronavirus 229E infected Huh-7 cells. Transmission electron microscopy revealed that DMV formation in infected cells was significantly reduced in the presence of the inhibitor. Furthermore, we found that (i) viral RTCs colocalized with LPL containing membranes, (ii) cellular LPL concentrations were increased in coronavirus-infected cells, and (iii) this increase was diminished in the presence of the cPLA2alpha inhibitor Py-2. Py-2 also displayed antiviral activities against other viruses representing the Coronaviridae and Togaviridae families, while members of the Picornaviridae were not affected. Taken together, the study provides evidence that cPLA2alpha activity is critically involved in the replication of various +RNA virus families and may thus represent a candidate target for broad-spectrum antiviral drug development.IMPORTANCE Examples of highly conserved RNA virus proteins that qualify as drug targets for broad spectrum antivirals remain scarce, resulting in increased efforts to identify and specifically inhibit cellular functions that are essential for the replication of RNA viruses belonging to different genera and families. The present study supports and extends previous conclusions that enzymes involved in cellular lipid metabolism may be tractable targets for broad-spectrum antivirals. We obtained evidence to show that a cellular phospholipase, cPLA2alpha, which releases fatty acid from the sn-2 position of membrane-associated glycerophospholipids, is critically involved in coronavirus replication, most likely by producing lysophospholipids that are required to form the specialized membrane compartments in which viral RNA synthesis takes place. The importance of this enzyme in coronavirus replication and DMV formation is supported by several lines of evidence, including confocal and electron microscopy, viral replication, and lipidomics studies of coronavirus-infected cells treated with a highly specific cPLA2alpha inhibitor. PMID- 29167330 TI - Endothelial Cell Metabolism. AB - Endothelial cells (ECs) are more than inert blood vessel lining material. Instead, they are active players in the formation of new blood vessels (angiogenesis) both in health and (life-threatening) diseases. Recently, a new concept arose by which EC metabolism drives angiogenesis in parallel to well established angiogenic growth factors (e.g., vascular endothelial growth factor). 6-Phosphofructo-2-kinase/fructose-2,6-bisphosphatase-3-driven glycolysis generates energy to sustain competitive behavior of the ECs at the tip of a growing vessel sprout, whereas carnitine palmitoyltransferase 1a-controlled fatty acid oxidation regulates nucleotide synthesis and proliferation of ECs in the stalk of the sprout. To maintain vascular homeostasis, ECs rely on an intricate metabolic wiring characterized by intracellular compartmentalization, use metabolites for epigenetic regulation of EC subtype differentiation, crosstalk through metabolite release with other cell types, and exhibit EC subtype-specific metabolic traits. Importantly, maladaptation of EC metabolism contributes to vascular disorders, through EC dysfunction or excess angiogenesis, and presents new opportunities for anti-angiogenic strategies. Here we provide a comprehensive overview of established as well as newly uncovered aspects of EC metabolism. PMID- 29167340 TI - Human Adenovirus Core Protein V Is Targeted by the Host SUMOylation Machinery To Limit Essential Viral Functions. AB - Human adenoviruses (HAdV) are nonenveloped viruses containing a linear, double stranded DNA genome surrounded by an icosahedral capsid. To allow proper viral replication, the genome is imported through the nuclear pore complex associated with viral core proteins. Until now, the role of these incoming virion proteins during the early phase of infection was poorly understood. The core protein V is speculated to bridge the core and the surrounding capsid. It binds the genome in a sequence-independent manner and localizes in the nucleus of infected cells, accumulating at nucleoli. Here, we show that protein V contains conserved SUMO conjugation motifs (SCMs). Mutation of these consensus motifs resulted in reduced SUMOylation of the protein; thus, protein V represents a novel target of the host SUMOylation machinery. To understand the role of protein V SUMO posttranslational modification during productive HAdV infection, we generated a replication competent HAdV with SCM mutations within the protein V coding sequence. Phenotypic analyses revealed that these SCM mutations are beneficial for adenoviral replication. Blocking protein V SUMOylation at specific sites shifts the onset of viral DNA replication to earlier time points during infection and promotes viral gene expression. Simultaneously, the altered kinetics within the viral life cycle are accompanied by more efficient proteasomal degradation of host determinants and increased virus progeny production than that observed during wild-type infection. Taken together, our studies show that protein V SUMOylation reduces virus growth; hence, protein V SUMOylation represents an important novel aspect of the host antiviral strategy to limit virus replication and thereby points to potential intervention strategies.IMPORTANCE Many decades of research have revealed that HAdV structural proteins promote viral entry and mainly physical stability of the viral genome in the capsid. Our work over the last years showed that this concept needs expansion as the functions are more diverse. We showed that capsid protein VI regulates the antiviral response by modulation of the transcription factor Daxx during infection. Moreover, core protein VII interacts with SPOC1 restriction factor, which is beneficial for efficient viral gene expression. Here, we were able to show that core protein V also represents a novel substrate of the host SUMOylation machinery and contains several conserved SCMs; mutation of these consensus motifs reduced SUMOylation of the protein. Unexpectedly, we observed that introducing these mutations into HAdV promotes adenoviral replication. In conclusion, we offer novel insights into adenovirus core proteins and provide evidence that SUMOylation of HAdV factors regulates replication efficiency. PMID- 29167341 TI - Novel Synthesis and Phenotypic Analysis of Mutant Clouds for Hepatitis E Virus Genotype 1. AB - Many RNA viruses exist as an ensemble of genetically diverse, replicating populations known as a mutant cloud. The genetic diversity (cloud size) and composition of this mutant cloud may influence several important phenotypic features of the virus, including its replication capacity. We applied a straightforward, bacterium-free approach using error-prone PCR coupled with reverse genetics to generate infectious mutant RNA clouds with various levels of genetic diversity from a genotype 1 strain of hepatitis E virus (HEV). Cloning and sequencing of a genomic fragment encompassing 70% of open reading frame 1 (ORF1) or of the full genome from variants in the resultant clouds showed the occurrence of nucleotide mutations at a frequency on the order of 10-3 per nucleotide copied and the existence of marked genetic diversity, with a high normalized Shannon entropy value. The mutant clouds showed transient replication in cell culture, while wild-type HEV did not. Cross-sectional data from these cell cultures supported the existence of differential effects of clouds of various sizes and compositions on phenotypic characteristics, such as the replication level of (+)-RNA progeny, the amounts of double-stranded RNA (a surrogate for the rate of viral replication) and ORF1 protein, and the expression of interferon-stimulated genes. Since mutant cloud size and composition influenced the viral phenotypic properties, a better understanding of this relationship may help to provide further insights into virus evolution and prediction of emerging viral diseases.IMPORTANCE Several biological or practical limitations currently prevent the study of phenotypic behavior of a mutant cloud in vitro We developed a simple and rapid method for synthesizing mutant clouds of hepatitis E virus (HEV), a single-stranded (+)-RNA [ss(+) RNA] virus, with various and controllable levels of genetic diversity, which could then be used in a cell culture system to study the effects of cloud size and composition on viral phenotype. In a cross-sectional analysis, we demonstrated that a particular mutant cloud which had an extremely high genetic diversity had a replication rate exceeding that of wild-type HEV. This method should thus provide a useful model for understanding the phenotypic behavior of ss(+) RNA viruses. PMID- 29167343 TI - Ubiquitination of the Cytoplasmic Domain of Influenza A Virus M2 Protein Is Crucial for Production of Infectious Virus Particles. AB - Virus replication is mediated by interactions between the virus and host. Here, we demonstrate that influenza A virus membrane protein 2 (M2) can be ubiquitinated. The lysine residue at position 78, which is located in the cytoplasmic domain of M2, is essential for M2 ubiquitination. An M2-K78R (Lys78 >Arg78) mutant, which produces ubiquitination-deficient M2, showed a severe defect in the production of infectious virus particles. M2-K78R mutant progeny contained more hemagglutinin (HA) proteins, less viral RNAs, and less internal viral proteins, including M1 and NP, than the wild-type virus. Furthermore, most of the M2-K78R mutant viral particles lacked viral ribonucleoproteins upon examination by electron microscopy and exhibited slightly lower densities. We also found that mutant M2 colocalized with the M1 protein to a lesser extent than for the wild-type virus. These findings may account for the reduced incorporation of viral ribonucleoprotein into virions. By blocking the second round of virus infection, we showed that the M2 ubiquitination-defective mutant exhibited normal levels of virus replication during the first round of infection, thereby proving that M2 ubiquitination is involved in the virus production step. Finally, we found that the M2-K78R mutant virus induced autophagy and apoptosis earlier than did the wild-type virus. Collectively, these results suggest that M2 ubiquitination plays an important role in infectious virus production by coordinating the efficient packaging of the viral genome into virus particles and the timing of virus-induced cell death.IMPORTANCE Annual epidemics and recurring pandemics of influenza viruses represent very high global health and economic burdens. The influenza virus M2 protein has been extensively studied for its important roles in virus replication, particularly in virus entry and release. Rimantadine, one of the most commonly used antiviral drugs, binds to the channel lumen near the N terminus of M2 proteins. However, viruses that are resistant to rimantadine have emerged. M2 undergoes several posttranslational modifications, such as phosphorylation and palmitoylation. Here, we reveal that ubiquitination mediates the functional role of M2. A ubiquitination-deficient M2 mutant predominately produced virus particles either lacking viral ribonucleoproteins or containing smaller amounts of internal viral components, resulting in lower infectivity. Our findings offer insights into the mechanism of influenza virus morphogenesis, particularly the functional role of M1-M2 interactions in viral particle assembly, and can be applied to the development of new influenza therapies. PMID- 29167342 TI - Antibodies Directed toward Neuraminidase N1 Control Disease in a Mouse Model of Influenza. AB - There is increasing evidence to suggest that antibodies directed toward influenza A virus (IAV) neuraminidase (NA) are an important correlate of protection against influenza in humans. Moreover, the potential of NA-specific antibodies to provide broader protection than conventional hemagglutinin (HA) antibodies has been recognized. Here, we describe the isolation of two monoclonal antibodies, N1-7D3 and N1-C4, directed toward the N1 NA. N1-7D3 binds to a conserved linear epitope in the membrane-distal, carboxy-terminal part of the NA and reacted with the NA of seasonal H1N1 isolates ranging from 1977 to 2007 and the 2009 H1N1pdm virus, as well as A/Vietnam/1194/04 (H5N1). However, N1-7D3 lacked NA inhibition (NI) activity and the ability to protect BALB/c mice against a lethal challenge with a range of H1N1 viruses. Conversely, N1-C4 bound to a conformational epitope that is conserved between two influenza virus subtypes, 2009 H1N1pdm and H5N1 IAV, and displayed potent in vitro antiviral activity mediating both NI and plaque size reduction. Moreover, N1-C4 could provide heterosubtypic protection in BALB/c mice against a lethal challenge with 2009 H1N1pdm or H5N1 virus. Glutamic acid residue 311 in the NA was found to be critical for the NA binding and antiviral activity of monoclonal antibody N1-C4. Our data provide further evidence for cross protective epitopes within the N1 subtype and highlight the potential of NA as an important target for vaccine and therapeutic approaches.IMPORTANCE Influenza remains a worldwide burden on public health. As such, the development of novel vaccines and therapeutics against influenza virus is crucial. Human challenge studies have recently highlighted the importance of antibodies directed toward the viral neuraminidase (NA) as an important correlate of reduced influenza associated disease severity. Furthermore, there is evidence that anti-NA antibodies can provide broader protection than antibodies toward the viral hemagglutinin. Here, we describe the isolation and detailed characterization of two N1 NA-specific monoclonal antibodies. One of these monoclonal antibodies broadly binds N1-type NAs, and the second displays NA inhibition and in vitro and in vivo antiviral activity against 2009 H1N1pdm and H5N1 influenza viruses. These two new anti-NA antibodies contribute to our understanding of the antigenic properties and protective potential of the influenza virus NA antigen. PMID- 29167344 TI - Comparison of the Efficacy of N9 Neuraminidase-Specific Monoclonal Antibodies against Influenza A(H7N9) Virus Infection. AB - The fifth wave of A(H7N9) virus infection in China from 2016 to 2017 caused great concern due to the large number of individuals infected, the isolation of drug resistant viruses, and the emergence of highly pathogenic strains. Antibodies against neuraminidase (NA) provide added benefit to hemagglutinin-specific immunity and may be important contributors to the effectiveness of A(H7N9) vaccines. We generated a panel of mouse monoclonal antibodies (MAbs) to identify antigenic domains on NA of the novel A(H7N9) virus and compared their functional properties. The loop formed in the region of residue 250 (250 loop) and the domain formed by the loops containing residues 370, 400, and 430 were identified as major antigenic regions. MAbs 1E8, 2F6, 10F4, and 11B2, which recognize these two antigenic domains, were characterized in depth. These four MAbs differ in their abilities to inhibit cleavage of small and large substrates (methyl umbelliferyl-acetyl neuraminic acid [MU-NANA] and fetuin, respectively) in NA inhibition assays. 1E8 and 11B2 did not inhibit NA cleavage of either MU-NANA or fetuin, and 2F6 inhibited cleavage of fetuin alone, whereas 10F4 inhibited cleavage of both substrates. All four MAbs reduced the in vitro spread of viruses carrying either the wild-type N9 or N9 with antiviral-resistant mutations but to different degrees. These MAbs have different in vivo levels of effectiveness: 10F4 was the most effective in protecting mice against challenge with A(H7N9) virus, 2F6 was less effective, and 11B2 failed to protect BALB/c mice at the doses tested. Our study confirms that NA-specific antibodies can protect against A(H7N9) infection and suggests that in vitro properties can be used to rank antibodies with therapeutic potential.IMPORTANCE The novel A(H7N9) viruses that emerged in China in 2013 continue to infect humans, with a high fatality rate. The most recent outbreak resulted in a larger number of human cases than previous epidemic waves. Due to the absence of a licensed vaccine and the emergence of drug-resistant viruses, there is a need to develop alternative approaches to prevent or treat A(H7N9) infection. We have made a panel of mouse monoclonal antibodies (MAbs) specific for neuraminidase (NA) of A(H7N9) viruses; some of these MAbs are effective in inhibiting viruses that are resistant to antivirals used to treat A(H7N9) patients. Binding avidity, inhibition of NA activity, and plaque formation correlated with the effectiveness of these MAbs to protect mice against lethal A(H7N9) virus challenge. This study identifies in vitro measures that can be used to predict the in vivo efficacy of NA-specific antibodies, providing a way to select MAbs for further therapeutic development. PMID- 29167345 TI - Merkel Cell Polyomavirus Infection of Animal Dermal Fibroblasts. AB - Merkel cell polyomavirus (MCPyV) is the first polyomavirus to be associated with human cancer. Mechanistic studies attempting to fully elucidate MCPyV's oncogenic mechanisms have been hampered by the lack of animal models for MCPyV infection. In this study, we examined the ability of MCPyV-GFP pseudovirus (containing a green fluorescent protein [GFP] reporter construct), MCPyV recombinant virions, and several MCPyV chimeric viruses to infect dermal fibroblasts isolated from various model animals, including mouse (Mus musculus), rabbit (Oryctolagus cuniculus), rat (Rattus norvegicus), chimpanzee (Pan troglodytes), rhesus macaque (Macaca mulatta), patas monkey (Erythrocebus patas), common woolly monkey (Lagothrix lagotricha), red-chested mustached tamarin (Saguinus labiatus), and tree shrew (Tupaia belangeri). We found that MCPyV-GFP pseudovirus was able to enter the dermal fibroblasts of all species tested. Chimpanzee dermal fibroblasts were the only type that supported vigorous MCPyV gene expression and viral replication, and they did so to a level beyond that of human dermal fibroblasts. We further demonstrated that both human and chimpanzee dermal fibroblasts produce infectious MCPyV virions that can successfully infect new cells. In addition, rat dermal fibroblasts supported robust MCPyV large T antigen expression after infection with an MCPyV chimeric virus in which the entire enhancer region of the MCPyV early promoter has been replaced with the simian virus 40 (SV40) analog. Our results suggest that viral transcription and/or replication events represent the major hurdle for MCPyV cross-species transmission. The capacity of rat dermal fibroblasts to support MCPyV early gene expression suggests that the rat is a candidate model organism for studying viral oncogene function during Merkel cell carcinoma (MCC) oncogenic progression.IMPORTANCE MCPyV plays an important role in the development of a highly aggressive form of skin cancer, Merkel cell carcinoma (MCC). With the increasing number of MCC diagnoses, there is a need to better understand the virus and its oncogenic potential. However, studies attempting to fully elucidate MCPyV's oncogenic mechanisms have been hampered by the lack of animal models for MCPyV infection. To pinpoint the best candidate for developing an MCPyV infection animal model, we examined MCPyV's ability to infect dermal fibroblasts isolated from various established model animals. Of the animal cell types we tested, chimpanzee dermal fibroblasts were the only isolates that supported the full MCPyV infectious cycle. To overcome the infection blockade in the other model animals, we constructed chimeric viruses that achieved robust MCPyV entry and oncogene expression in rat fibroblasts. Our results suggest that the rat may serve as an in vivo model to study MCV oncogenesis. PMID- 29167346 TI - Glycine Zipper Motifs in Hepatitis C Virus Nonstructural Protein 4B Are Required for the Establishment of Viral Replication Organelles. AB - Hepatitis C virus (HCV) RNA replication occurs in tight association with remodeled host cell membranes, presenting as cytoplasmic accumulations of single , double-, and multimembrane vesicles in infected cells. Formation of these so called replication organelles is mediated by a complex interplay of host cell factors and viral replicase proteins. Of these, nonstructural protein 4B (NS4B), an integral transmembrane protein, appears to play a key role, but little is known about the molecular mechanisms of how this protein contributes to organelle biogenesis. Using forward and reverse genetics, we identified glycine zipper motifs within transmembrane helices 2 and 3 of NS4B that are critically involved in viral RNA replication. Foerster resonance energy transfer analysis revealed the importance of the glycine zippers in NS4B homo- and heterotypic self interactions. Additionally, ultrastructural analysis using electron microscopy unraveled a prominent role of glycine zipper residues for the subcellular distribution and the morphology of HCV-induced double-membrane vesicles. Notably, loss-of-function NS4B glycine zipper mutants prominently induced single-membrane vesicles with secondary invaginations that might represent an arrested intermediate state in double-membrane vesicle formation. These findings highlight a so-far-unknown role of glycine residues within the membrane integral core domain for NS4B self-interaction and functional as well as structural integrity of HCV replication organelles.IMPORTANCE Remodeling of the cellular endomembrane system leading to the establishment of replication organelles is a hallmark of positive-strand RNA viruses. In the case of HCV, expression of the nonstructural proteins induces the accumulation of double-membrane vesicles that likely arise from a concerted action of viral and coopted cellular factors. However, the underlying molecular mechanisms are incompletely understood. Here, we identify glycine zipper motifs within HCV NS4B transmembrane segments 2 and 3 that are crucial for the protein's self-interaction. Moreover, glycine residues within NS4B transmembrane helices critically contribute to the biogenesis of functional replication organelles and, thus, efficient viral RNA replication. These results reveal how glycine zipper motifs in NS4B contribute to structural and functional integrity of the HCV replication organelles and, thus, viral RNA replication. PMID- 29167348 TI - Pregnancy is detected via odour in a wild cooperative breeder. AB - Among mammals, scent has long been known to encode oestrus; however, in many species, detecting pregnancy may also be important in terms of both competition and mate-choice. Here, we show, through odour presentation experiments, that pregnancy is discernible via scent by both sexes in the cooperatively breeding banded mongoose, Mungos mungo Males spent more time investigating and were more likely to scent mark the odours of non-pregnant females, compared to pregnant females. Females showed increased levels of scent marking when odours were of the same reproductive state as themselves. These results present the first direct demonstration that pregnancy is detectable via scent in wild cooperative breeders. Detecting pregnancy may be particularly important in cooperative breeders as, in addition to the competition between males for receptive mates, there is also intense competition between females for access to alloparental care. Consequently, dominant females benefit from targeting reproductive suppression towards subordinates that represent direct threats, such as pregnant females. PMID- 29167347 TI - Novel Role of vBcl2 in the Virion Assembly of Kaposi's Sarcoma-Associated Herpesvirus. AB - The viral Bcl-2 homolog (vBcl2) of Kaposi's sarcoma-associated herpesvirus (KSHV) displays efficient antiapoptotic and antiautophagic activity through its central BH3 domain, which functions to prolong the life span of virus-infected cells and ultimately enhances virus replication and latency. Independent of its antiapoptotic and antiautophagic activity, vBcl2 also plays an essential role in KSHV lytic replication through its amino-terminal amino acids (aa) 11 to 20. Here, we report a novel molecular mechanism of vBcl2-mediated regulation of KSHV lytic replication. vBcl2 specifically bound the tegument protein open reading frame 55 (ORF55) through its amino-terminal aa 11 to 20, allowing their association with virions. Consequently, the vBcl2 peptide derived from vBcl2 aa 11 to 20 effectively disrupted the interaction between vBcl2 and ORF55, inhibiting the incorporation of the ORF55 tegument protein into virions. This study provides new insight into vBcl2's function in KSHV virion assembly that is separable from its inhibitory role in host apoptosis and autophagy.IMPORTANCE KSHV, an important human pathogen accounting for a large percentage of virally caused cancers worldwide, has evolved a variety of stratagems for evading host immune responses to establish lifelong persistent infection. Upon viral infection, infected cells can go through programmed cell death, including apoptosis and autophagy, which plays an effective role in antiviral responses. To counter the host response, KSHV vBcl2 efficiently blocks apoptosis and autophagy to persist for the life span of virus-infected cells. Besides its anti-programmed cell-death activity, vBcl2 also interacts with the ORF55 tegument protein for virion assembly in infected cells. Interestingly, the vBcl2 peptide disrupts the vBcl2-ORF55 interaction and effectively inhibits KSHV virion assembly. This study indicates that KSHV vBcl2 harbors at least three genetically separable functions to modulate both host cell death signaling and virion production and that the vBcl2 peptide can be developed as an anti-KSHV therapeutic application. PMID- 29167349 TI - Left-handedness and time pressure in elite interactive ball games. AB - According to the fighting hypothesis, frequency-dependent selection gives relatively rarer left-handers a competitive edge in duel-like contests and is suggested as one mechanism that ensured the stable maintenance of handedness polymorphism in humans. Overrepresentation of left-handers exclusively in interactive sports seems to support the hypothesis. Here, by referring to data on interactive ball sports, I propose that a left-hander's advantage is linked to the sports' underlying time pressure. The prevalence of left-handers listed in elite rankings increased from low (8.7%) to high (30.39%) time pressure sports and a distinct left-hander overrepresentation was only found in the latter (i.e. baseball, cricket and table tennis). This indicates that relative rarity and the interactive nature of a contest are not sufficient per se to evoke a left-hander advantage. Refining the fighting hypothesis is suggested to facilitate prediction and experimental verification of when and why negative frequency-dependent selection may benefit left-handedness. PMID- 29167350 TI - Safinamide Differentially Modulates In Vivo Glutamate and GABA Release in the Rat Hippocampus and Basal Ganglia. AB - Safinamide has been recently approved as an add-on to levodopa therapy for Parkinson disease. In addition to inhibiting monoamine oxidase type B, it blocks sodium channels and modulates glutamate (Glu) release in vitro. Since this property might contribute to the therapeutic action of the drug, we undertook the present study to investigate whether safinamide inhibits Glu release also in vivo and whether this effect is consistent across different brain areas and is selective for glutamatergic neurons. To this aim, in vivo microdialysis was used to monitor the spontaneous and veratridine-induced Glu and GABA release in the hippocampus and basal ganglia of naive, awake rats. Brain levels of safinamide were measured as well. To shed light on the mechanisms underlying the effect of safinamide, sodium currents were measured by patch-clamp recording in rat cortical neurons. Safinamide maximally inhibited the veratridine-induced Glu and GABA release in hippocampus at 15 mg/kg, which reached free brain concentrations of 1.89-1.37 uM. This dose attenuated veratridine-stimulated Glu (but not GABA) release in subthalamic nucleus, globus pallidus, and substantia nigra reticulata, but not in striatum. Safinamide was ineffective on spontaneous neurotransmitter release. In vitro, safinamide inhibited sodium channels, showing a greater affinity at depolarized (IC50 = 8 uM) than at resting (IC50 = 262 uM) potentials. We conclude that safinamide inhibits in vivo Glu release from stimulated nerve terminals, likely via blockade of sodium channels at subpopulations of neurons with specific firing patterns. These data are consistent with the anticonvulsant and antiparkinsonian actions of safinamide and provide support for the nondopaminergic mechanism of its action. PMID- 29167352 TI - Two spatially distinct kinesin-14 proteins, Pkl1 and Klp2, generate collaborative inward forces against kinesin-5 Cut7 in S. pombe. AB - Kinesin motors play central roles in bipolar spindle assembly. In many eukaryotes, spindle pole separation is driven by kinesin-5, which generates outward force. This outward force is balanced by antagonistic inward force elicited by kinesin-14 and/or dynein. In fission yeast, two kinesin-14 proteins, Pkl1 and Klp2, play an opposing role against the kinesin-5 motor protein Cut7. However, how the two kinesin-14 proteins coordinate individual activities remains elusive. Here, we show that although deletion of either pkl1 or klp2 rescues temperature-sensitive cut7 mutants, deletion of only pkl1 can bypass the lethality caused by cut7 deletion. Pkl1 is tethered to the spindle pole body, whereas Klp2 is localized along the spindle microtubule. Forced targeting of Klp2 to the spindle pole body, however, compensates for Pkl1 functions, indicating that cellular localizations, rather than individual motor specificities, differentiate between the two kinesin-14 proteins. Interestingly, human kinesin 14 (KIFC1 or HSET) can replace either Pkl1 or Klp2. Moreover, overproduction of HSET induces monopolar spindles, reminiscent of the phenotype of Cut7 inactivation. Taken together, this study has uncovered the biological mechanism whereby two different Kinesin-14 motor proteins exert their antagonistic roles against kinesin-5 in a spatially distinct manner. PMID- 29167351 TI - Longitudinal FGF23 Trajectories and Mortality in Patients with CKD. AB - Elevated fibroblast growth factor 23 (FGF23) levels, measured at a single time, are strongly associated with increased risk of mortality in patients with CKD. There are minimal data on serial FGF23 measurements in CKD. In a prospective case cohort study of the Chronic Renal Insufficiency Cohort, we measured FGF23 at two to five annual time points (mean 4.0+/-1.2) in a randomly selected subcohort of 1135 participants, of whom 203 died, and all remaining 390 participants who died through mid-2013. Higher FGF23 was independently associated with increased risk of death in multivariable-adjusted analyses of time-varying FGF23 (hazard ratio per 1-SD increase in ln-transformed FGF23, 1.84; 95% CI, 1.67 to 2.03). Median FGF23 was stable over 5 years of follow-up, but its gradually right-skewed distribution suggested a subpopulation with markedly elevated FGF23. Trajectory analysis revealed three distinct trajectories: stable FGF23 in the majority of participants (slope of lnFGF23 per year =0.03, 95% CI, 0.02 to 0.04, n=724) and smaller subpopulations with slowly (slope=0.14, 95% CI, 0.12 to 0.16, n=486) or rapidly (slope=0.46, 95% CI, 0.38 to 0.54, n=99) rising levels. Compared with stable FGF23, participants with slowly rising FGF23 trajectories were at 4.49 fold higher risk of death (95% CI, 3.17 to 6.35) and individuals with rapidly rising FGF23 trajectories were at 15.23-fold higher risk of death (95% CI, 8.24 to 28.14) in fully adjusted analyses. Trajectory analyses that used four or three annual FGF23 measurements yielded qualitatively similar results. In conclusion, FGF23 levels are stable over time in the majority of patients with CKD, but serial measurements identify subpopulations with rising levels and exceptionally high risk of death. PMID- 29167353 TI - Coordinated Regulation of Hypocotyl Cell Elongation by Light and Ethylene through a Microtubule Destabilizing Protein. AB - Precise regulation of hypocotyl cell elongation is essential for plant growth and survival. Light suppresses hypocotyl elongation by degrading transcription factor phytochrome-interacting factor 3 (PIF3), whereas the phytohormone ethylene promotes hypocotyl elongation by activating PIF3. However, the underlying mechanisms regarding how these two pathways coordinate downstream effectors to mediate hypocotyl elongation are largely unclear. In this study, we identified the novel Microtubule-Destabilizing Protein 60 (MDP60), which plays a positive role in hypocotyl cell elongation in Arabidopsis (Arabidopsis thaliana); this effect is mediated through PIF3. Ethylene signaling up-regulates MDP60 expression via PIF3 binding to the MDP60 promoter. MDP60 loss-of-function mutants exhibit much shorter hypocotyls, whereas MDP60 overexpression significantly promotes hypocotyl cell elongation when grown in light compared to the control. MDP60 protein binds to microtubules in vitro and in vivo. The organization of cortical microtubules was significantly disrupted in mdp60 mutant cells and MDP60 overexpressing seedlings. These findings indicate that MDP60 is an important mediator of hypocotyl cell elongation. This study reveals a mechanism in which light and ethylene signaling coordinate MDP60 expression to modulate hypocotyl cell elongation by altering cortical microtubules in Arabidopsis.

AB - Teleost fishes evolved livebearing via egg retention 14 times. Matrotrophy has evolved within 12 of those lineages. By contrast, squamate reptiles evolved livebearing over 115 times, but only two to four of those lineages are known to have evolved matrotrophy. Is the discrepancy between these organisms in the probability of this transition caused by differences in their eggs? We show that the eggs of oviparous species in the superorder Atherinomorpha can acquire small organic molecules from their surrounding environment against a concentration gradient via mechanisms of active transport. Uptake rates were inhibited by competing radiolabelled amino acids against unlabelled versions of themselves. Transport was non-specific as uptake rates were similar for l-leucine and its biologically uncommon enantiomer d-leucine. Eggs are also capable of transporting larger microspheres across the membrane, but transport is inhibited at temperatures below 4 degrees C, suggesting active transport occurs via pinocytosis. Conflict theory predicts that the ability of the egg to acquire maternal resources will facilitate the embryo-parent arms race that leads to the evolution of matrotrophy following the transition to livebearing. The shelled eggs of amniotes lack such access to maternal resources when retained in the evolution of viviparity. PMID- 29167358 TI - Spatial memory shapes density dependence in population dynamics. AB - Most population dynamics studies assume that individuals use space uniformly, and thus mix well spatially. In numerous species, however, individuals do not move randomly, but use spatial memory to visit renewable resource patches repeatedly. To understand the extent to which memory-based foraging movement may affect density-dependent population dynamics through its impact on competition, we developed a spatially explicit, individual-based movement model where reproduction and death are functions of foraging efficiency. We compared the dynamics of populations of with- and without-memory individuals. We showed that memory-based movement leads to a higher population size at equilibrium, to a higher depletion of the environment, to a marked discrepancy between the global (i.e. measured at the population level) and local (i.e. measured at the individual level) intensities of competition, and to a nonlinear density dependence. These results call for a deeper investigation of the impact of individual movement strategies and cognitive abilities on population dynamics. PMID- 29167359 TI - Genome diversity in the Neolithic Globular Amphorae culture and the spread of Indo-European languages. AB - It is unclear whether Indo-European languages in Europe spread from the Pontic steppes in the late Neolithic, or from Anatolia in the Early Neolithic. Under the former hypothesis, people of the Globular Amphorae culture (GAC) would be descended from Eastern ancestors, likely representing the Yamnaya culture. However, nuclear (six individuals typed for 597 573 SNPs) and mitochondrial (11 complete sequences) DNA from the GAC appear closer to those of earlier Neolithic groups than to the DNA of all other populations related to the Pontic steppe migration. Explicit comparisons of alternative demographic models via approximate Bayesian computation confirmed this pattern. These results are not in contrast to Late Neolithic gene flow from the Pontic steppes into Central Europe. However, they add nuance to this model, showing that the eastern affinities of the GAC in the archaeological record reflect cultural influences from other groups from the East, rather than the movement of people. PMID- 29167360 TI - The effect of climate change on the duration of avian breeding seasons: a meta analysis. AB - Many bird species are advancing the timing of their egg-laying in response to a warming climate. Little is known, however, of whether this advancement affects the respective length of the breeding seasons. A meta-analysis of 65 long-term studies of 54 species from the Northern Hemisphere has revealed that within the last 45 years an average population has lengthened the season by 1.4 days per decade, which was independent from changes in mean laying dates. Multi-brooded birds have prolonged their seasons by 4 days per decade, while single-brooded have shortened by 2 days. Changes in season lengths covaried with local climate changes: warming was correlated with prolonged seasons in multi-brooded species, but not in single-brooders. This might be a result of higher ecological flexibility of multi-brooded birds, whereas single brooders may have problems with synchronizing their reproduction with the peak of food resources. Sedentary species and short-distance migrants prolonged their breeding seasons more than long-distance migrants, which probably cannot track conditions at their breeding grounds. We conclude that as long as climate warming continues without major changes in ecological conditions, multi-brooded or sedentary species will probably increase their reproductive output, while the opposite effect may occur in single-brooded or migratory birds. PMID- 29167361 TI - Food-web dynamics under climate change. AB - Climate change affects ecological communities through its impact on the physiological performance of individuals. However, the population dynamic of species well inside their thermal niche is also determined by competitors, prey and predators, in addition to being influenced by temperature changes. We use a trait-based food-web model to examine how the interplay between the direct physiological effects from temperature and the indirect effects due to changing interactions between populations shapes the ecological consequences of climate change for populations and for entire communities. Our simulations illustrate how isolated communities deteriorate as populations go extinct when the environment moves outside the species' thermal niches. High-trophic-level species are most vulnerable, while the ecosystem function of lower trophic levels is less impacted. Open communities can compensate for the loss of ecosystem function by invasions of new species. Individual populations show complex responses largely uncorrelated with the direct impact of temperature change on physiology. Such complex responses are particularly evident during extinction and invasion events of other species, where climatically well-adapted species may be brought to extinction by the changed food-web topology. Our results highlight that the impact of climate change on specific populations is largely unpredictable, and apparently well-adapted species may be severely impacted. PMID- 29167362 TI - Reply to comments by Olson et al. 2017 and Stien 2017. PMID- 29167363 TI - Long-term archives reveal shifting extinction selectivity in China's postglacial mammal fauna. AB - Ecosystems have been modified by human activities for millennia, and insights about ecology and extinction risk based only on recent data are likely to be both incomplete and biased. We synthesize multiple long-term archives (over 250 archaeological and palaeontological sites dating from the early Holocene to the Ming Dynasty and over 4400 historical records) to reconstruct the spatio-temporal dynamics of Holocene-modern range change across China, a megadiverse country experiencing extensive current-day biodiversity loss, for 34 mammal species over three successive postglacial time intervals. Our combined zooarchaeological, palaeontological, historical and current-day datasets reveal that both phylogenetic and spatial patterns of extinction selectivity have varied through time in China, probably in response both to cumulative anthropogenic impacts (an 'extinction filter' associated with vulnerable species and accessible landscapes being affected earlier by human activities) and also to quantitative and qualitative changes in regional pressures. China has experienced few postglacial global species-level mammal extinctions, and most species retain over 50% of their maximum estimated Holocene range despite millennia of increasing regional human pressures, suggesting that the potential still exists for successful species conservation and ecosystem restoration. Data from long-term archives also demonstrate that herbivores have experienced more historical extinctions in China, and carnivores have until recently displayed greater resilience. Accurate assessment of patterns of biodiversity loss and the likely predictive power of current-day correlates of faunal vulnerability and resilience is dependent upon novel perspectives provided by long-term archives. PMID- 29167364 TI - Fear of predation shapes social network structure and the acquisition of foraging information in guppy shoals. AB - Spatio-temporal variation in predation risk is predicted to select for plastic anti-predator responses, which may in turn impact the fine-scale social structure of prey groups and processes mediated by that structure. To test these predictions, we manipulated the ambient predation risk experienced by Trinidadian guppy (Poecilia reticulata) groups before quantifying their social networks and recording individual latencies to approach and solve a novel foraging task. High risk conditions drove the formation of social networks that were more strongly assorted by body size than those exposed to low ambient risk and promoted longer durations of contact between preferred partners. Additionally, high background predation risk reduced the probability individuals would approach and solve a novel foraging task. Network-based diffusion analysis revealed that while social transmission of the task solution from knowledgeable to naive individuals occurred at a higher rate within low-risk groups, individuals in high-risk groups were particularly likely to investigate the task while shoaling with preferred social partners. Taken together, our results suggest that the structure and functional importance of prey social networks may partly depend on local predation pressure. Furthermore, by influencing individuals' access to information, fear of predation may impact decision-making in a potentially wide array of behavioural contexts. PMID- 29167365 TI - Correlated individual differences suggest a common mechanism underlying metacognition in visual perception and visual short-term memory. AB - Adaptive behaviour depends on the ability to introspect accurately about one's own performance. Whether this metacognitive ability is supported by the same mechanisms across different tasks is unclear. We investigated the relationship between metacognition of visual perception and metacognition of visual short-term memory (VSTM). Experiments 1 and 2 required subjects to estimate the perceived or remembered orientation of a grating stimulus and rate their confidence. We observed strong positive correlations between individual differences in metacognitive accuracy between the two tasks. This relationship was not accounted for by individual differences in task performance or average confidence, and was present across two different metrics of metacognition and in both experiments. A model-based analysis of data from a third experiment showed that a cross-domain correlation only emerged when both tasks shared the same task-relevant stimulus feature. That is, metacognition for perception and VSTM were correlated when both tasks required orientation judgements, but not when the perceptual task was switched to require contrast judgements. In contrast with previous results comparing perception and long-term memory, which have largely provided evidence for domain-specific metacognitive processes, the current findings suggest that metacognition of visual perception and VSTM is supported by a domain-general metacognitive architecture, but only when both domains share the same task relevant stimulus feature. PMID- 29167367 TI - Embryonic origin of the gnathostome vertebral skeleton. AB - The vertebral column is a key component of the jawed vertebrate (gnathostome) body plan, but the primitive embryonic origin of this skeleton remains unclear. In tetrapods, all vertebral components (neural arches, haemal arches and centra) derive from paraxial mesoderm (somites). However, in teleost fishes, vertebrae have a dual embryonic origin, with arches derived from somites, but centra formed, in part, by secretion of bone matrix from the notochord. Here, we test the embryonic origin of the vertebral skeleton in a cartilaginous fish (the skate, Leucoraja erinacea) which serves as an outgroup to tetrapods and teleosts. We demonstrate, by cell lineage tracing, that both arches and centra are somite derived. We find no evidence of cellular or matrix contribution from the notochord to the skate vertebral skeleton. These findings indicate that the earliest gnathostome vertebral skeleton was exclusively of somitic origin, with a notochord contribution arising secondarily in teleosts. PMID- 29167366 TI - Archaeogenomic analysis of the first steps of Neolithization in Anatolia and the Aegean. AB - The Neolithic transition in west Eurasia occurred in two main steps: the gradual development of sedentism and plant cultivation in the Near East and the subsequent spread of Neolithic cultures into the Aegean and across Europe after 7000 cal BCE. Here, we use published ancient genomes to investigate gene flow events in west Eurasia during the Neolithic transition. We confirm that the Early Neolithic central Anatolians in the ninth millennium BCE were probably descendants of local hunter-gatherers, rather than immigrants from the Levant or Iran. We further study the emergence of post-7000 cal BCE north Aegean Neolithic communities. Although Aegean farmers have frequently been assumed to be colonists originating from either central Anatolia or from the Levant, our findings raise alternative possibilities: north Aegean Neolithic populations may have been the product of multiple westward migrations, including south Anatolian emigrants, or they may have been descendants of local Aegean Mesolithic groups who adopted farming. These scenarios are consistent with the diversity of material cultures among Aegean Neolithic communities and the inheritance of local forager know-how. The demographic and cultural dynamics behind the earliest spread of Neolithic culture in the Aegean could therefore be distinct from the subsequent Neolithization of mainland Europe. PMID- 29167368 TI - Perception of contextual size illusions by honeybees in restricted and unrestricted viewing conditions. AB - How different visual systems process images and make perceptual errors can inform us about cognitive and visual processes. One of the strongest geometric errors in perception is a misperception of size depending on the size of surrounding objects, known as the Ebbinghaus or Titchener illusion. The ability to perceive the Ebbinghaus illusion appears to vary dramatically among vertebrate species, and even populations, but this may depend on whether the viewing distance is restricted. We tested whether honeybees perceive contextual size illusions, and whether errors in perception of size differed under restricted and unrestricted viewing conditions. When the viewing distance was unrestricted, there was an effect of context on size perception and thus, similar to humans, honeybees perceived contrast size illusions. However, when the viewing distance was restricted, bees were able to judge absolute size accurately and did not succumb to visual illusions, despite differing contextual information. Our results show that accurate size perception depends on viewing conditions, and thus may explain the wide variation in previously reported findings across species. These results provide insight into the evolution of visual mechanisms across vertebrate and invertebrate taxa, and suggest convergent evolution of a visual processing solution. PMID- 29167369 TI - Correction to 'Deceptive vocal duets and multi-modal display in a songbird'. PMID- 29167370 TI - Uncertainty, epistemics and active inference. AB - Biological systems-like ourselves-are constantly faced with uncertainty. Despite noisy sensory data, and volatile environments, creatures appear to actively maintain their integrity. To account for this remarkable ability to make optimal decisions in the face of a capricious world, we propose a generative model that represents the beliefs an agent might possess about their own uncertainty. By simulating a noisy and volatile environment, we demonstrate how uncertainty influences optimal epistemic (visual) foraging. In our simulations, saccades were deployed less frequently to regions with a lower sensory precision, while a greater volatility led to a shorter inhibition of return. These simulations illustrate a principled explanation for some cardinal aspects of visual foraging and allow us to propose a correspondence between the representation of uncertainty and ascending neuromodulatory systems, complementing that suggested by Yu & Dayan (Yu & Dayan 2005 Neuron46, 681-692. (doi:10.1016/j.neuron.2005.04.026)). PMID- 29167371 TI - Spontaneous oscillations of elastic filaments induced by molecular motors. AB - It is known from the wave-like motion of microtubules in motility assays that the piconewton forces that motors produce can be sufficient to bend the filaments. In cellular phenomena such as cytosplasmic streaming, molecular motors translocate along cytoskeletal filaments, carrying cargo which entrains fluid. When large numbers of such forced filaments interact through the surrounding fluid, as in particular stages of oocyte development in Drosophila melanogaster, complex dynamics are observed, but the detailed mechanics underlying them has remained unclear. Motivated by these observations, we study here perhaps the simplest model for these phenomena: an elastic filament, pinned at one end, acted on by a molecular motor treated as a point force. Because the force acts tangential to the filament, no matter what its shape, this 'follower-force' problem is intrinsically non-variational, and thereby differs fundamentally from Euler buckling, where the force has a fixed direction, and which, in the low-Reynolds number regime, ultimately leads to a stationary, energy-minimizing shape. Through a combination of linear stability theory, analytical study of a solvable simplified 'two-link' model and numerical studies of the full elastohydrodynamic equations of motion, we elucidate the Hopf bifurcation that occurs with increasing forcing of a filament, leading to flapping motion analogous to the high-Reynolds-number oscillations of a garden hose with a free end. PMID- 29167372 TI - Effects of spanwise flexibility on the performance of flapping flyers in forward flight. AB - Flying animals possess flexible wings that deform during flight. The chordwise flexibility alters the wing shape, affecting the effective angle of attack and hence the surrounding aerodynamics. However, the effects of spanwise flexibility on the locomotion are inadequately understood. Here, we present a two-way coupled aeroelastic model of a plunging spanwise flexible wing. The aerodynamics is modelled with a two-dimensional, unsteady, incompressible potential flow model, evaluated at each spanwise location of the wing. The two-way coupling is realized by considering the transverse displacement as the effective plunge under the dynamic balance of wing inertia, elastic restoring force and aerodynamic force. The thrust is a result of the competition between the enhancement due to wing deformation and induced drag. The results for a purely plunging spanwise flexible wing agree well with experimental and high-fidelity numerical results from the literature. Our analysis suggests that the wing aspect ratio of the abstracted passerine and goose models corresponds to the optimal aeroelastic response, generating the highest thrust while minimizing the power required to flap the wings. At these optimal aspect ratios, the flapping frequency is near the first spanwise natural frequency of the wing, suggesting that these birds may benefit from the resonance to generate thrust. PMID- 29167373 TI - Epitranscriptomic profiling across cell types reveals associations between APOBEC1-mediated RNA editing, gene expression outcomes, and cellular function. AB - Epitranscriptomics refers to posttranscriptional alterations on an mRNA sequence that are dynamic and reproducible, and affect gene expression in a similar way to epigenetic modifications. However, the functional relevance of those modifications for the transcript, the cell, and the organism remain poorly understood. Here, we focus on RNA editing and show that Apolipoprotein B mRNA editing enzyme, catalytic polypeptide-1 (APOBEC1), together with its cofactor RBM47, mediates robust editing in different tissues. The majority of editing events alter the sequence of the 3'UTR of targeted transcripts, and we focus on one cell type (monocytes) and on a small set of highly edited transcripts within it to show that editing alters gene expression by modulating translation (but not RNA stability or localization). We further show that specific cellular processes (phagocytosis and transendothelial migration) are enriched for transcripts that are targets of editing and that editing alters their function. Finally, we survey bone marrow progenitors and demonstrate that common monocyte progenitor cells express high levels of APOBEC1 and are susceptible to loss of the editing enzyme. Overall, APOBEC1-mediated transcriptome diversification is required for the fine tuning of protein expression in monocytes, suggesting an epitranscriptomic mechanism for the proper maintenance of homeostasis in innate immune cells. PMID- 29167374 TI - FMRFamide-like peptides expand the behavioral repertoire of a densely connected nervous system. AB - Animals, including humans, can adapt to environmental stress through phenotypic plasticity. The free-living nematode Caenorhabditis elegans can adapt to harsh environments by undergoing a whole-animal change, involving exiting reproductive development and entering the stress-resistant dauer larval stage. The dauer is a dispersal stage with dauer-specific behaviors for finding and stowing onto carrier animals, but how dauers acquire these behaviors, despite having a physically limited nervous system of 302 neurons, is poorly understood. We compared dauer and reproductive development using whole-animal RNA sequencing at fine time points and at sufficient depth to measure transcriptional changes within single cells. We detected 8,042 genes differentially expressed during dauer and reproductive development and observed striking up-regulation of neuropeptide genes during dauer entry. We knocked down neuropeptide processing using sbt-1 mutants and demonstrate that neuropeptide signaling promotes the decision to enter dauer rather than reproductive development. We also demonstrate that during dauer neuropeptides modulate the dauer-specific nictation behavior (carrier animal-hitchhiking) and are necessary for switching from repulsion to CO2 (a carrier animal cue) in nondauers to CO2 attraction in dauers. We tested individual neuropeptides using CRISPR knockouts and existing strains and demonstrate that the combined effects of flp-10 and flp-17 mimic the effects of sbt-1 on nictation and CO2 attraction. Through meta-analysis, we discovered similar up-regulation of neuropeptides in the dauer-like infective juveniles of diverse parasitic nematodes, suggesting the antiparasitic target potential of SBT 1. Our findings reveal that, under stress, increased neuropeptide signaling in C. elegans enhances their decision-making accuracy and expands their behavioral repertoire. PMID- 29167376 TI - 4-Valent Human Papillomavirus (4vHPV) Vaccine in Preadolescents and Adolescents After 10 Years. AB - OBJECTIVES: We describe the final 10-year data for the long-term follow-up study of the 4-valent human papillomavirus (4vHPV) vaccine in preadolescents and adolescents. METHODS: In the base study (V501-018), 1661 sexually inactive boys and girls received the 4vHPV vaccine (early vaccination group [EVG], managed for 9.9 years) or a placebo at day 1, month 2, and month 6. Thereafter, at month 30, the placebo group (catch-up vaccination group [CVG], managed for 7.4 years) received the 4vHPV vaccine by using the same dosing schedule. Long-term anti-HPV type 6, 11, 16, and 18 immune responses were assessed. Effectiveness was estimated by calculating the incidence rate of the primary endpoints (HPV types 6, 11, 16, and 18-related disease or persistent infection). RESULTS: For HPV types 6, 11, and 16, 89% to 96% of subjects remained seropositive through 10 years postvaccination. The preadolescents had 38% to 65% higher geometric mean titers at month 7, which remained 16% to 42% higher at 10 years compared with adolescents. No cases of HPV type 6, 11, 16, and 18-related diseases were observed. Ten subjects had a persistent infection of >=6 months duration with vaccine-type HPV and 2 subjects had persistent infection for >=12 months. No new serious adverse events were reported through 10 years. CONCLUSIONS: A 3-dose regimen of the 4vHPV vaccine was immunogenic, clinically effective, and generally well tolerated in preadolescents and adolescents during 10 years of follow-up. These long-term findings support efforts to vaccinate this population against HPV before exposure. PMID- 29167375 TI - Loss of APOBEC1 RNA-editing function in microglia exacerbates age-related CNS pathophysiology. AB - Microglia (MG), a heterogeneous population of phagocytic cells, play important roles in central nervous system (CNS) homeostasis and neural plasticity. Under steady-state conditions, MG maintain homeostasis by producing antiinflammatory cytokines and neurotrophic factors, support myelin production, and remove synapses and cellular debris, as well as participating in "cross-correction," a process that supplies neurons with key factors for executing autophagy-lysosomal function. As sentinels for the immune system, MG also detect "danger" signals (pathogenic or traumatic insult), become activated, produce proinflammatory cytokines, and recruit monocytes and dendritic cells to the site of damage through a breached blood-brain barrier or via brain lymphatics. Failure to effectively resolve MG activation can be problematic and can lead to chronic inflammation, a condition proposed to underlie CNS pathophysiology in heritable brain disorders and age-related neurodegenerative and cognitive decline. Here, we show that APOBEC1-mediated RNA editing occurs within MG and is key to maintaining their resting status. Like bone marrow-derived macrophages, RNA editing in MG leads to overall changes in the abundance of edited proteins that coordinate the function of multiple cellular pathways. Conversely, mice lacking the APOBEC1 editing function in MG display evidence of dysregulation, with progressive age related signs of neurodegeneration, characterized by clustering of activated MG, aberrant myelination, increased inflammation, and lysosomal anomalies that culminate in behavioral and motor deficiencies. Collectively, our study identifies posttranscriptional modification by RNA editing as a critical regulatory mechanism of vital cellular functions that maintain overall brain health. PMID- 29167377 TI - Oropharyngeal Dysphagia and Cerebral Palsy. AB - OBJECTIVES: To determine the progression of oropharyngeal dysphagia (OPD) in preschool-aged children with cerebral palsy (CP) according to gross motor function. It was hypothesized that fewer children would have OPD at 60 months compared with 18 to 24 months (predominately Gross Motor Function Classification System [GMFCS] I-II). METHODS: Longitudinal population-based cohort of 179 children (confirmed CP diagnosis, born in Queensland in 2006-2009, aged 18-60 months at study entry [mean = 34.1 months +/- 11.9; 111 boys; GMFCS I = 46.6%, II = 12.9%, III = 15.7%, IV = 10.1%, and V = 14.6%]). Children had a maximum of 3 assessments (median = 3, total n = 423 assessments). OPD was classified by using the Dysphagia Disorders Survey part 2 and rated from video by a certified pediatric speech pathologist. GMFCS was used to classify children's gross motor function. RESULTS: OPD prevalence reduced from 79.7% at 18 to 24 months to 43.5% at 60 months. There were decreasing odds of OPD with increasing age (odds ratio [OR] = 0.92 [95% confidence interval (CI) 0.90 to 0.95]; P < .001) and increasing odds with poorer gross motor function (OR = 6.2 [95% CI 3.6 to 10.6]; P < .001). This reduction was significant for children with ambulatory CP (GMFCS I-II, OR = 0.93 [95% CI 0.90 to 0.96]; P < .001) but not significant for children from GMFCS III to V (OR [III] = 1.0 [95% CI 0.9 to 1.1]; P = .897; OR [IV-V] = 1.0 [95% CI 1.0 to 1.1]; P = .366). CONCLUSIONS: Half of the OPD present in children with CP between 18 and 24 months resolved by 60 months, with improvement most common in GMFCS I to II. To more accurately detect and target intervention at children with persisting OPD at 60 months, we suggest using a more conservative cut point of 6 out of 22 on the Dysphagia Disorders Survey for assessments between 18 and 48 months. PMID- 29167378 TI - Momentary Parental Stress and Food-Related Parenting Practices. AB - BACKGROUND: Research suggests that stress and depressed mood are associated with food-related parenting practices (ie, parent feeding practices, types of food served at meals). However, current measures of parental stress, depressed mood, and food-related parenting practices are typically survey-based and assessed as static/unchanging characteristics, failing to account for fluctuations across time and context. Identifying momentary factors that influence parent food related parenting practices will facilitate the development of effective interventions aimed at promoting healthy food-related parenting practices. In this study, we used ecological momentary assessment to examine the association between momentary factors (eg, stress, depressed mood) occurring early in the day and food-related parenting practices at the evening meal. METHODS: Children aged 5 to 7 years and their families (N = 150) from 6 racial and/or ethnic groups (n = 25 each African American, Hispanic/Latino, Hmong, American Indian, Somali, and white families) were recruited for this mixed-methods study through primary care clinics. RESULTS: Higher stress and depressed mood earlier in the day predicted pressure-to-eat feeding practices and fewer homemade foods served at meals the same night. Effect modification was found for certain racial and/or ethnic groups with regard to engaging in pressure-to-eat feeding practices (ie, America Indian, Somali) or serving fewer homemade meals (ie, African American, Hispanic/Latino) in the face of high stress or depressed mood. CONCLUSIONS: Clinicians may want to consider discussing with parents the influence stress and depressed mood can have on everyday food-related parenting practices. Additionally, future researchers should consider using real-time interventions to reduce parental stress and depressed mood to promote healthy parent food-related parenting practices. PMID- 29167379 TI - Tau can switch microtubule network organizations: from random networks to dynamic and stable bundles. AB - In neurons, microtubule networks alternate between single filaments and bundled arrays under the influence of effectors controlling their dynamics and organization. Tau is a microtubule bundler that stabilizes microtubules by stimulating growth and inhibiting shrinkage. The mechanisms by which tau organizes microtubule networks remain poorly understood. Here, we studied the self-organization of microtubules growing in the presence of tau isoforms and mutants. The results show that tau's ability to induce stable microtubule bundles requires two hexapeptides located in its microtubule-binding domain and is modulated by its projection domain. Site-specific pseudophosphorylation of tau promotes distinct microtubule organizations: stable single microtubules, stable bundles, or dynamic bundles. Disease-related tau mutations increase the formation of highly dynamic bundles. Finally, cryo-electron microscopy experiments indicate that tau and its variants similarly change the microtubule lattice structure by increasing both the protofilament number and lattice defects. Overall, our results uncover novel phosphodependent mechanisms governing tau's ability to trigger microtubule organization and reveal that disease-related modifications of tau promote specific microtubule organizations that may have a deleterious impact during neurodegeneration. PMID- 29167381 TI - CRISPR-Trap: a clean approach for the generation of gene knockouts and gene replacements in human cells. AB - CRISPR/Cas9-based genome editing offers the possibility to knock out almost any gene of interest in an affordable and simple manner. The most common strategy is the introduction of a frameshift into the open reading frame (ORF) of the target gene which truncates the coding sequence (CDS) and targets the corresponding transcript for degradation by nonsense-mediated mRNA decay (NMD). However, we show that transcripts containing premature termination codons (PTCs) are not always degraded efficiently and can generate C-terminally truncated proteins which might have residual or dominant negative functions. Therefore, we recommend an alternative approach for knocking out genes, which combines CRISPR/Cas9 with gene traps (CRISPR-Trap) and is applicable to ~50% of all spliced human protein coding genes and a large subset of lncRNAs. CRISPR-Trap completely prevents the expression of the ORF and avoids expression of C-terminal truncated proteins. We demonstrate the feasibility of CRISPR-Trap by utilizing it to knock out several genes in different human cell lines. Finally, we also show that this approach can be used to efficiently generate gene replacements allowing for modulation of protein levels for otherwise lethal knockouts (KOs). Thus, CRISPR-Trap offers several advantages over conventional KO approaches and allows for generation of clean CRISPR/Cas9-based KOs. PMID- 29167380 TI - Self-oligomerization regulates stability of survival motor neuron protein isoforms by sequestering an SCFSlmb degron. AB - Spinal muscular atrophy (SMA) is caused by homozygous mutations in human SMN1 Expression of a duplicate gene (SMN2) primarily results in skipping of exon 7 and production of an unstable protein isoform, SMNDelta7. Although SMN2 exon skipping is the principal contributor to SMA severity, mechanisms governing stability of survival motor neuron (SMN) isoforms are poorly understood. We used a Drosophila model system and label-free proteomics to identify the SCFSlmb ubiquitin E3 ligase complex as a novel SMN binding partner. SCFSlmb interacts with a phosphor degron embedded within the human and fruitfly SMN YG-box oligomerization domains. Substitution of a conserved serine (S270A) interferes with SCFSlmb binding and stabilizes SMNDelta7. SMA-causing missense mutations that block multimerization of full-length SMN are also stabilized in the degron mutant background. Overexpression of SMNDelta7S270A, but not wild-type (WT) SMNDelta7, provides a protective effect in SMA model mice and human motor neuron cell culture systems. Our findings support a model wherein the degron is exposed when SMN is monomeric and sequestered when SMN forms higher-order multimers. PMID- 29167382 TI - Kinesin-6 KIF20B is required for efficient cytokinetic furrowing and timely abscission in human cells. AB - Cytokinesis requires the cooperation of many cytoskeletal and membrane regulators. Most of the major players required for cytokinesis are known, but the temporal regulation and adaptations for different cell types are less understood. KIF20B (previously called MPHOSPH1 or MPP1) is a member of the Kinesin-6 family, which also includes the better-known members KIF23/MKLP1 and KIF20A/MKLP2. Previously, we showed that mouse Kif20b is involved in cerebral cortex growth and midbody organization of neural stem cells. Here, using siRNA-mediated knockdown of KIF20B in a human cell line and fixed and live imaging, we show that KIF20B has a cell-autonomous role in cytokinesis. KIF20B depletion affects the speed of both furrow ingression and abscission. It localizes to microtubules of the central spindle and midbody throughout cytokinesis, at sites distinct from the other Kinesin-6 family members. KIF20B is not required for midbody assembly, but may accelerate or coordinate midbody maturation. In particular, KIF20B appears to regulate late steps of maturation including anillin dispersal, ESCRT-III recruitment, and the formation of microtubule constriction sites. PMID- 29167383 TI - C-terminal Src kinase (Csk) regulates the tricellular junction protein Gliotactin independent of Src. AB - Tricellular junctions (TCJs) are uniquely placed permeability barriers formed at the corners of polarized epithelia where tight junctions in vertebrates or septate junctions (SJ) in invertebrates from three cells converge. Gliotactin is a Drosophila TCJ protein, and loss of Gliotactin results in SJ and TCJ breakdown and permeability barrier loss. When overexpressed, Gliotactin spreads away from the TCJs, resulting in disrupted epithelial architecture, including overproliferation, cell delamination, and migration. Gliotactin levels are tightly controlled at the mRNA level and at the protein level through endocytosis and degradation triggered by tyrosine phosphorylation. We identified C-terminal Src kinase (Csk) as a tyrosine kinase responsible for regulating Gliotactin endocytosis. Increased Csk suppresses the Gliotactin overexpression phenotypes by increasing endocytosis. Loss of Csk causes Gliotactin to spread away from the TCJ. Although Csk is known as a negative regulator of Src kinases, the effects of Csk on Gliotactin are independent of Src and likely occur through an adherens junction associated complex. Overall, we identified a new Src-independent role for Csk in the control of Gliotactin, a key tricellular junction protein. PMID- 29167385 TI - Do Intracerebral Hemorrhage Nonexpanders Actually Expand Into the Ventricular Space? AB - BACKGROUND AND PURPOSE: The computed tomographic angiography spot sign as a predictor of hematoma expansion is limited by its modest sensitivity and positive predictive value. It is possible that hematoma expansion in spot-positive patients is missed because of decompression of intracerebral hemorrhage (ICH) into the ventricular space. We hypothesized that revising hematoma expansion definitions to include intraventricular hemorrhage (IVH) expansion will improve the predictive performance of the spot sign. Our objectives were to determine the proportion of ICH nonexpanders who actually have IVH expansion, determine the proportion of false-positive spot signs that have IVH expansion, and compare the known predictive performance of the spot sign to a revised definition incorporating IVH expansion. METHODS: We analyzed patients from the multicenter PREDICT ICH spot sign study. We defined hematoma expansion as >=6 mL or >=33% ICH expansion or >2 mL IVH expansion and compared spot sign performance using this revised definition with the conventional 6 mL/33% definition using receiver operating curve analysis. RESULTS: Of 311 patients, 213 did not meet the 6-mL/33% expansion definition (nonexpanders). Only 13 of 213 (6.1%) nonexpanders had >=2 mL IVH expansion. Of the false-positive spot signs, 4 of 40 (10%) had >2 mL ventricular expansion. The area under the curve for spot sign to predict significant ICH expansion was 0.65 (95% confidence interval, 0.58-0.72), which was no different than when IVH expansion was added to the definition (area under the curve, 0.66; 95% confidence interval, 0.58-0.71). CONCLUSIONS: Although IVH expansion does indeed occur in a minority of ICH nonexpanders, its inclusion into a revised hematoma expansion definition does not alter the predictive performance of the spot sign. PMID- 29167384 TI - DRC2/CCDC65 is a central hub for assembly of the nexin-dynein regulatory complex and other regulators of ciliary and flagellar motility. AB - The nexin-dynein regulatory complex (N-DRC) plays a central role in the regulation of ciliary and flagellar motility. In most species, the N-DRC contains at least 11 subunits, but the specific function of each subunit is unknown. Mutations in three subunits (DRC1, DRC2/CCDC65, DRC4/GAS8) have been linked to defects in ciliary motility in humans and lead to a ciliopathy known as primary ciliary dyskinesia (PCD). Here we characterize the biochemical, structural, and motility phenotypes of two mutations in the DRC2 gene of Chlamydomonas Using high resolution proteomic and structural approaches, we find that the C-terminal region of DRC2 is critical for the coassembly of DRC2 and DRC1 to form the base plate of N-DRC and its attachment to the outer doublet microtubule. Loss of DRC2 in drc2 mutants disrupts the assembly of several other N-DRC subunits and also destabilizes the assembly of several closely associated structures such as the inner dynein arms, the radial spokes, and the calmodulin- and spoke-associated complex. Our study provides new insights into the range of ciliary defects that can lead to PCD. PMID- 29167386 TI - Ischemic Stroke Profile, Risk Factors, and Outcomes in India: The Indo-US Collaborative Stroke Project. AB - BACKGROUND AND PURPOSE: The Indo-US Collaborative Stroke Project was designed to characterize ischemic stroke across 5 high-volume academic tertiary hospitals in India. METHODS: From January 2012 to August 2014, research coordinators and physician coinvestigators prospectively collected data on 2066 patients with ischemic stroke admitted <2 weeks after onset. Investigator training and supervision and data monitoring were conducted by the US site (Massachusetts General Hospital, Boston). RESULTS: The mean age was 58.3+/-14.7 years, 67.2% men. The median admission National Institutes of Health Stroke Scale score was 10 (interquartile range, 5-15) and 24.5% had National Institutes of Health Stroke Scale >=16. Hypertension (60.8%), diabetes mellitus (35.7%), and tobacco use (32.2%, including bidi/smokeless tobacco) were common risk factors. Only 4% had atrial fibrillation. All patients underwent computed tomography or magnetic resonance imaging; 81% had cerebrovascular imaging. Stroke etiologic subtypes were large artery (29.9%), cardiac (24.9%), small artery (14.2%), other definite (3.4%), and undetermined (27.6%, including 6.7% with incomplete evaluation). Intravenous or intra-arterial thrombolysis was administered in 13%. In-hospital mortality was 7.9%, and 48% achieved modified Rankin Scale score 0 to 2 at 90 days. On multivariate analysis, diabetes mellitus predicted poor 3-month outcome and younger age, lower admission National Institutes of Health Stroke Scale and small-artery etiology predicted excellent 3-month outcome. CONCLUSIONS: These comprehensive and novel clinical imaging data will prove useful in refining stroke guidelines and advancing stroke care in India. PMID- 29167387 TI - Prehospital Systolic Blood Pressure Is Related to Intracerebral Hemorrhage Volume on Admission. AB - BACKGROUND AND PURPOSE: Ultra-early blood pressure (BP) management in the prehospital setting could improve the efficacy of this treatment on attenuating intracerebral hemorrhage (ICH) expansion. We aimed to determine the association of prehospital systolic BP (SBP) with ICH volume, ultra-early hematoma growth, and the spot sign on admission. METHODS: We conducted a retrospective study of a prospective database of 219 consecutive patients with spontaneous ICH admitted to the emergency department of a tertiary stroke center during a 3-year period. Prehospital SBP and ICH volume, ultra-early hematoma growth (ICH volume/onset-to imaging time), and presence of the spot sign on admission were prospectively recorded. Primary outcome was ICH volume on admission. Secondary outcomes included ultra-early hematoma growth and frequency of the spot sign in patients scanned within 6 hours from symptom onset (hyperacute group). RESULTS: Prehospital SBP was positively correlated with both SBP (r=0.552; P<0.001) and ICH volume (rho=0.189; P=0.006) on admission. Patients with ICH volume above the median value presented higher prehospital SBP (172.3+/-35.0 versus 163.7+/-27.8 mm Hg; P=0.049). This association remained significant in adjusted multiple logistic regression analysis (odds ratio, 1.01 for a 1-U increase in SBP; 95% confidence interval, 1.01-1.02; P=0.018). In the hyperacute group (n=126), prehospital SBP was unrelated to ultra-early hematoma growth (rho=0.115; P=0.203) nor the presence of the spot sign (172.2+/-27.6 versus 171.8+/-31.6 mm Hg; P=0.959). CONCLUSIONS: Prehospital SBP is correlated with SBP on admission and independently associated with ICH volume on admission. These findings support the rationale of testing whether prehospital initiation of BP-lowering attenuates ICH expansion. PMID- 29167388 TI - Real-World Use of Apixaban for Stroke Prevention in Atrial Fibrillation: A Systematic Review and Meta-Analysis. AB - BACKGROUND AND PURPOSE: The use of oral anticoagulant therapy for stroke prevention in atrial fibrillation has been transformed by the availability of the nonvitamin K antagonist oral anticoagulants. Real-world studies on the use of nonvitamin K antagonist oral anticoagulants would help elucidate their effectiveness and safety in daily clinical practice. Apixaban was the third nonvitamin K antagonist oral anticoagulants introduced to clinical practice, and increasing real-world studies have been published. Our aim was to summarize current evidence about real-world studies on apixaban for stroke prevention in atrial fibrillation. METHODS: We performed a systematic review and meta-analysis of all observational real-world studies comparing apixaban with other available oral anticoagulant drugs. RESULTS: From the original 9680 results retrieved, 16 studies have been included in the final meta-analysis. Compared with warfarin, apixaban regular dose was more effective in reducing any thromboembolic event (odds ratio: 0.77; 95% confidence interval: 0.64-0.93), but no significant difference was found for stroke risk. Apixaban was as effective as dabigatran and rivaroxaban in reducing thromboembolic events and stroke. The risk of major bleeding was significantly lower for apixaban compared with warfarin, dabigatran, and rivaroxaban (relative risk reduction, 38%, 35%, and 46%, respectively). Similarly, the risk for intracranial hemorrhage was significantly lower for apixaban than warfarin and rivaroxaban (46% and 54%, respectively) but not dabigatran. The risk of gastrointestinal bleeding was lower with apixaban when compared with all oral anticoagulant agents (P<0.00001 for all comparisons). CONCLUSIONS: Use of apixaban in real-life is associated with an overall similar effectiveness in reducing stroke and any thromboembolic events when compared with warfarin. A better safety profile was found with apixaban compared with warfarin, dabigatran, and rivaroxaban. PMID- 29167389 TI - Symptomatic Intracranial Atherosclerosis With Impaired Distal Perfusion: A Case Study. PMID- 29167390 TI - Early Elevated Troponin Levels After Ischemic Stroke Suggests a Cardioembolic Source. AB - BACKGROUND AND PURPOSE: Elevated cardiac troponin is a marker of cardiac disease and has been recently shown to be associated with embolic stroke risk. We hypothesize that early elevated troponin levels in the acute stroke setting are more prevalent in patients with embolic stroke subtypes (cardioembolic and embolic stroke of unknown source) as opposed to noncardioembolic subtypes (large vessel disease, small-vessel disease, and other). METHODS: We abstracted data from our prospective ischemic stroke database and included all patients with ischemic stroke during an 18-month period. Per our laboratory, we defined positive troponin as >=0.1 ng/mL and intermediate as >=0.06 ng/mL and <0.1 ng/mL. Unadjusted and adjusted regression models were built to determine the association between stroke subtype (embolic stroke of unknown source and cardioembolic subtypes) and positive and intermediate troponin levels, adjusting for key confounders, including demographics (age and sex), clinical characteristics (hypertension, hyperlipidemia, diabetes mellitus, renal function, coronary heart disease, congestive heart failure, current smoking, and National Institutes of Health Stroke Scale score), cardiac variables (left atrial diameter, wall-motion abnormalities, ejection fraction, and PR interval on ECG), and insular involvement of infarct. RESULTS: We identified 1234 patients, of whom 1129 had admission troponin levels available; 10.0% (113/1129) of these had a positive troponin. In fully adjusted models, there was an association between troponin positivity and embolic stroke of unknown source subtype (adjusted odds ratio, 4.46; 95% confidence interval, 1.03-7.97; P=0.003) and cardioembolic stroke subtype (odds ratio, 5.00; 95% confidence interval, 1.83-13.63; P=0.002). CONCLUSIONS: We found that early positive troponin after ischemic stroke may be independently associated with a cardiac embolic source. Future studies are needed to confirm our findings using high-sensitivity troponin assays and to test optimal secondary prevention strategies in patients with embolic stroke of unknown source and positive troponin. PMID- 29167391 TI - Integrated genomic and interfacility patient-transfer data reveal the transmission pathways of multidrug-resistant Klebsiella pneumoniae in a regional outbreak. AB - Development of effective strategies to limit the proliferation of multidrug resistant organisms requires a thorough understanding of how such organisms spread among health care facilities. We sought to uncover the chains of transmission underlying a 2008 U.S. regional outbreak of carbapenem-resistant Klebsiella pneumoniae by performing an integrated analysis of genomic and interfacility patient-transfer data. Genomic analysis yielded a high-resolution transmission network that assigned directionality to regional transmission events and discriminated between intra- and interfacility transmission when epidemiologic data were ambiguous or misleading. Examining the genomic transmission network in the context of interfacility patient transfers (patient sharing networks) supported the role of patient transfers in driving the outbreak, with genomic analysis revealing that a small subset of patient-transfer events was sufficient to explain regional spread. Further integration of the genomic and patient-sharing networks identified one nursing home as an important bridge facility early in the outbreak-a role that was not apparent from analysis of genomic or patient-transfer data alone. Last, we found that when simulating a real-time regional outbreak, our methodology was able to accurately infer the facility at which patients acquired their infections. This approach has the potential to identify facilities with high rates of intra- or interfacility transmission, data that will be useful for triggering targeted interventions to prevent further spread of multidrug-resistant organisms. PMID- 29167392 TI - TCR engagement negatively affects CD8 but not CD4 CAR T cell expansion and leukemic clearance. AB - Chimeric antigen receptor (CAR)-expressing T cells induce durable remissions in patients with relapsed/refractory B cell malignancies. CARs are synthetic constructs that, when introduced into mature T cells, confer a second, non-major histocompatibility complex-restricted specificity in addition to the endogenous T cell receptor (TCR). The implications of TCR activation on CAR T cell efficacy has not been well defined. Using an immunocompetent, syngeneic murine model of CD19-targeted CAR T cell therapy for pre-B cell acute lymphoblastic leukemia in which the CAR is introduced into T cells with known TCR specificity, we demonstrate loss of CD8 CAR T cell efficacy associated with T cell exhaustion and apoptosis when TCR antigen is present. CD4 CAR T cells demonstrate equivalent cytotoxicity to CD8 CAR T cells and, in contrast, retain in vivo efficacy despite TCR stimulation. Gene expression profiles confirm increased exhaustion and apoptosis of CD8 CAR T cells upon dual receptor stimulation compared to CD4 CAR T cells and indicate inherent differences between CD4 and CD8 CAR T cells in the use of T cell-associated signaling pathways. These results provide insights into important aspects of CAR T cell immune biology and indicate opportunities to rationally design CAR constructs to optimize clinical efficacy. PMID- 29167393 TI - What evidence do we need for biomarker qualification? AB - Biomarkers can facilitate all aspects of the drug development process. However, biomarker qualification-the use of a biomarker that is accepted by the U.S. Food and Drug Administration-needs a clear, predictable process. We describe a multistakeholder effort including government, industry, and academia that proposes a framework for defining the amount of evidence needed for biomarker qualification. This framework is intended for broad applications across multiple biomarker categories and uses.

AB - Sporadic Creutzfeldt-Jakob disease (sCJD), the most common human prion disease, is transmissible through iatrogenic routes due to abundant infectious prions [misfolded forms of the prion protein (PrPSc)] in the central nervous system (CNS). Some epidemiological studies have associated sCJD risk with non-CNS surgeries. We explored the potential prion seeding activity and infectivity of skin from sCJD patients. Autopsy or biopsy skin samples from 38 patients [21 sCJD, 2 variant CJD (vCJD), and 15 non-CJD] were analyzed by Western blotting and real-time quaking-induced conversion (RT-QuIC) for PrPSc Skin samples from two patients were further examined for prion infectivity by bioassay using two lines of humanized transgenic mice. Western blotting revealed dermal PrPSc in one of five deceased sCJD patients and one of two vCJD patients. However, the more sensitive RT-QuIC assay detected prion seeding activity in skin from all 23 CJD decedents but not in skin from any non-CJD control individuals (with other neurological conditions or other diseases) during blinded testing. Although sCJD patient skin contained ~103- to 105-fold lower prion seeding activity than did sCJD patient brain tissue, all 12 mice from two transgenic mouse lines inoculated with sCJD skin homogenates from two sCJD patients succumbed to prion disease within 564 days after inoculation. Our study demonstrates that the skin of sCJD patients contains both prion seeding activity and infectivity, which raises concerns about the potential for iatrogenic sCJD transmission via skin.

AB - Biliary atresia is a progressive infantile cholangiopathy of complex pathogenesis. Although early diagnosis and surgery are the best predictors of treatment response, current diagnostic approaches are imprecise and time consuming. We used large-scale, quantitative serum proteomics at the time of diagnosis of biliary atresia and other cholestatic syndromes (serving as disease controls) to identify biomarkers of disease. In a discovery cohort of 70 subjects, the lead biomarker was matrix metalloproteinase-7 (MMP-7), which retained high distinguishing features for biliary atresia in two validation cohorts. Notably, the diagnostic performance reached 95% when MMP-7 was combined with gamma-glutamyltranspeptidase (GGT), a marker of cholestasis. Using human tissue and an experimental model of biliary atresia, we found that MMP-7 is primarily expressed by cholangiocytes, released upon epithelial injury, and promotes the experimental disease phenotype. Thus, we propose that serum MMP-7 (alone or in combination with GGT) is a diagnostic biomarker for biliary atresia and may serve as a therapeutic target.

PMID- 29167396 TI - Targeting STUB1-tissue factor axis normalizes hyperthrombotic uremic phenotype without increasing bleeding risk. AB - Chronic kidney disease (CKD/uremia) remains vexing because it increases the risk of atherothrombosis and is also associated with bleeding complications on standard antithrombotic/antiplatelet therapies. Although the associations of indolic uremic solutes and vascular wall proteins [such as tissue factor (TF) and aryl hydrocarbon receptor (AHR)] are being defined, the specific mechanisms that drive the thrombotic and bleeding risks are not fully understood. We now present an indolic solute-specific animal model, which focuses on solute-protein interactions and shows that indolic solutes mediate the hyperthrombotic phenotype across all CKD stages in an AHR- and TF-dependent manner. We further demonstrate that AHR regulates TF through STIP1 homology and U-box-containing protein 1 (STUB1). As a ubiquitin ligase, STUB1 dynamically interacts with and degrades TF through ubiquitination in the uremic milieu. TF regulation by STUB1 is supported in humans by an inverse relationship of STUB1 and TF expression and reduced STUB1 TF interaction in uremic vessels. Genetic or pharmacological manipulation of STUB1 in vascular smooth muscle cells inhibited thrombosis in flow loops. STUB1 perturbations reverted the uremic hyperthrombotic phenotype without prolonging the bleeding time, in contrast to heparin, the standard-of-care antithrombotic in CKD patients. Our work refines the thrombosis axis (STUB1 is a mediator of indolic solute-AHR-TF axis) and expands the understanding of the interconnected relationships driving the fragile thrombotic state in CKD. It also establishes a means of minimizing the uremic hyperthrombotic phenotype without altering the hemostatic balance, a long-sought-after combination in CKD patients. PMID- 29167400 TI - Tonotopic Variation of the T-Type Ca2+ Current in Avian Auditory Coincidence Detector Neurons. AB - Neurons in avian nucleus laminaris (NL) are binaural coincidence detectors for sound localization and are characterized by striking structural variations in dendrites and axon initial segment (AIS) according to their acoustic tuning [characteristic frequency (CF)]. T-type Ca2+ (CaT) channels regulate synaptic integration and firing behavior at these neuronal structures. However, whether or how CaT channels contribute to the signal processing in NL neurons is not known. In this study, we addressed this issue with whole-cell recording and two-photon Ca2+ imaging in brain slices of posthatch chicks of both sexes. We found that the CaT current was prominent in low-CF neurons, whereas it was almost absent in higher-CF neurons. In addition, a large Ca2+ transient occurred at the dendrites and the AIS of low-CF neurons, indicating a localization of CaT channels at these structures in the neurons. Because low-CF neurons have long dendrites, dendritic CaT channels may compensate for the attenuation of EPSPs at dendrites. Furthermore, the short distance of AIS from the soma may accelerate activation of axonal CaT current in the neurons and help EPSPs reach spike threshold. Indeed, the CaT current was activated by EPSPs and augmented the synaptic response and spike generation of the neurons. Notably, the CaT current was inactivated during repetitive inputs, and these augmenting effects predominated at the initial phase of synaptic activity. These results suggested that dendritic and axonal CaT channels increase the sensitivity to sound at its onset, which may expand the dynamic range for binaural computation in low-CF NL neurons.SIGNIFICANCE STATEMENT Neurons in nucleus laminaris are binaural coincidence detectors for sound localization. We report that T-type Ca2+ (CaT) current was prominent at dendrites and the axonal trigger zone in neurons tuned to low-frequency sound. Because these neurons have long dendrites and a closer trigger zone compared with those tuned to higher-frequency sound, the CaT current augmented EPSPs at dendrites and accelerated spike triggers in the neurons, implying a strategic arrangement of the current within the nucleus. This effect was limited to the onset of repetitive inputs due to progressive inactivation of CaT current. The results suggested that the CaT current increases the sensitivity to sound at its onset, which may expand the dynamic range for binaural computation of low frequency sound. PMID- 29167399 TI - Protein O-Mannosyltransferases Affect Sensory Axon Wiring and Dynamic Chirality of Body Posture in the Drosophila Embryo. AB - Genetic defects in protein O-mannosyltransferase 1 (POMT1) and POMT2 underlie severe muscular dystrophies. POMT genes are evolutionarily conserved in metazoan organisms. In Drosophila, both male and female POMT mutants show a clockwise rotation of adult abdominal segments, suggesting a chirality of underlying pathogenic mechanisms. Here we described and analyzed a similar phenotype in POMT mutant embryos that shows left-handed body torsion. Our experiments demonstrated that coordinated muscle contraction waves are associated with asymmetric embryo rolling, unveiling a new chirality marker in Drosophila development. Using genetic and live-imaging approaches, we revealed that the torsion phenotype results from differential rolling and aberrant patterning of peristaltic waves of muscle contractions. Our results demonstrated that peripheral sensory neurons are required for normal contractions that prevent the accumulation of torsion. We found that POMT mutants show abnormal axonal connections of sensory neurons. POMT transgenic expression limited to sensory neurons significantly rescued the torsion phenotype, axonal connectivity defects, and abnormal contractions in POMT mutant embryos. Together, our data suggested that protein O-mannosylation is required for normal sensory feedback to control coordinated muscle contractions and body posture. This mechanism may shed light on analogous functions of POMT genes in mammals and help to elucidate the etiology of neurological defects in muscular dystrophies.SIGNIFICANCE STATEMENT Protein O-mannosyltransferases (POMTs) are evolutionarily conserved in metazoans. Mutations in POMTs cause severe muscular dystrophies associated with pronounced neurological defects. However, neurological functions of POMTs remain poorly understood. We demonstrated that POMT mutations in Drosophila result in abnormal muscle contractions and cause embryo torsion. Our experiments uncovered a chirality of embryo movements and a unique POMT-dependent mechanism that maintains symmetry of a developing system affected by chiral forces. Furthermore, POMTs were found to be required for proper axon connectivity of sensory neurons, suggesting that O mannosylation regulates the sensory feedback controlling muscle contractions. This novel POMT function in the peripheral nervous system may shed light on analogous functions in mammals and help to elucidate pathomechanisms of neurological abnormalities in muscular dystrophies. PMID- 29167401 TI - Acetaminophen Relieves Inflammatory Pain through CB1 Cannabinoid Receptors in the Rostral Ventromedial Medulla. AB - Acetaminophen (paracetamol) is a widely used analgesic and antipyretic drug with only incompletely understood mechanisms of action. Previous work, using models of acute nociceptive pain, indicated that analgesia by acetaminophen involves an indirect activation of CB1 receptors by the acetaminophen metabolite and endocannabinoid reuptake inhibitor AM 404. However, the contribution of the cannabinoid system to antihyperalgesia against inflammatory pain, the main indication of acetaminophen, and the precise site of the relevant CB1 receptors have remained elusive. Here, we analyzed acetaminophen analgesia in mice of either sex with inflammatory pain and found that acetaminophen exerted a dose dependent antihyperalgesic action, which was mimicked by intrathecally injected AM 404. Both compounds lost their antihyperalgesic activity in CB1-/- mice, confirming the involvement of the cannabinoid system. Consistent with a mechanism downstream of proinflammatory prostaglandin formation, acetaminophen also reversed hyperalgesia induced by intrathecal prostaglandin E2 To distinguish between a peripheral/spinal and a supraspinal action, we administered acetaminophen and AM 404 to hoxB8-CB1-/- mice, which lack CB1 receptors from the peripheral nervous system and the spinal cord. These mice exhibited unchanged antihyperalgesia indicating a supraspinal site of action. Accordingly, local injection of the CB1 receptor antagonist rimonabant into the rostral ventromedial medulla blocked acetaminophen-induced antihyperalgesia, while local rostral ventromedial medulla injection of AM 404 reduced hyperalgesia in wild-type mice but not in CB1-/- mice. Our results indicate that the cannabinoid system contributes not only to acetaminophen analgesia against acute pain but also against inflammatory pain, and suggest that the relevant CB1 receptors reside in the rostral ventromedial medulla.SIGNIFICANCE STATEMENT Acetaminophen is a widely used analgesic drug with multiple but only incompletely understood mechanisms of action, including a facilitation of endogenous cannabinoid signaling via one of its metabolites. Our present data indicate that enhanced cannabinoid signaling is also responsible for the analgesic effects of acetaminophen against inflammatory pain. Local injections of the acetaminophen metabolite AM 404 and of cannabinoid receptor antagonists as well as data from tissue-specific CB1 receptor-deficient mice suggest the rostral ventromedial medulla as an important site of the cannabinoid-mediated analgesia by acetaminophen. PMID- 29167402 TI - The Role of Cysteine String Protein alpha Phosphorylation at Serine 10 and 34 by Protein Kinase Cgamma for Presynaptic Maintenance. AB - Protein kinase Cgamma (PKCgamma) knock-out (KO) animals exhibit symptoms of Parkinson's disease (PD), including dopaminergic neuronal loss in the substantia nigra. However, the PKCgamma substrates responsible for the survival of dopaminergic neurons in vivo have not yet been elucidated. Previously, we found 10 potent substrates in the striatum of PKCgamma-KO mice. Here, we focused on cysteine string protein alpha (CSPalpha), a protein from the heat shock protein (HSP) 40 cochaperone families localized on synaptic vesicles. We found that in cultured cells, PKCgamma phosphorylates CSPalpha at serine (Ser) 10 and Ser34. Additionally, apoptosis was found to have been enhanced by the overexpression of a phosphorylation-null mutant of CSPalpha, CSPalpha(S10A/S34A). Compared with wild-type (WT) CSPalpha, the CSPalpha(S10A/S34A) mutant had a weaker interaction with HSP70. However, in sharp contrast, a phosphomimetic CSPalpha(S10D/S34D) mutant, compared with WT CSPalpha, had a stronger interaction with HSP70. In addition, total levels of synaptosomal-associated protein (SNAP) 25, a main downstream target of the HSC70/HSP70 chaperone complex, were found to have decreased by the CSPalpha(S10A/S34A) mutant through increased ubiquitination of SNAP25 in PC12 cells. In the striatum of 2-year-old male PKCgamma-KO mice, decreased phosphorylation levels of CSPalpha and decreased SNAP25 protein levels were observed. These findings indicate the phosphorylation of CSPalpha by PKCgamma may protect the presynaptic terminal from neurodegeneration. The PKCgamma-CSPalpha-HSC70/HSP70-SNAP25 axis, because of its role in protecting the presynaptic terminal, may provide a new therapeutic target for the treatment of PD.SIGNIFICANCE STATEMENT Cysteine string protein alpha (CSPalpha) is a protein belonging to the heat shock protein (HSP) 40 cochaperone families localized on synaptic vesicles, which maintain the presynaptic terminal. However, the function of CSPalpha phosphorylation by protein kinase C (PKC) for neuronal cell survival remains unclear. The experiments presented here demonstrate that PKCgamma phosphorylates CSPalpha at serine (Ser) 10 and Ser34. CSPalpha phosphorylation at Ser10 and Ser34 by PKCgamma protects the presynaptic terminal by promoting HSP70 chaperone activity. This report suggests that CSPalpha phosphorylation, because of its role in modulating HSP70 chaperone activity, may be a target for the treatment of neurodegeneration. PMID- 29167403 TI - Alpha Oscillations Reduce Temporal Long-Range Dependence in Spontaneous Human Brain Activity. AB - Ongoing neural dynamics comprise both frequency-specific oscillations and broadband-features, such as long-range dependence (LRD). Despite both being behaviorally relevant, little is known about their potential interactions. In humans, 8-12 Hz alpha oscillations constitute the strongest deviation from 1/f power-law scaling, the signature of LRD. We postulated that alpha oscillations, believed to exert active inhibitory gating, downmodulate the temporal width of LRD in slower ongoing brain activity. In two independent "resting-state" datasets (electroencephalography surface recordings and magnetoencephalography source reconstructions), both across space and dynamically over time, power of alpha activity covaried with the power slope <5 Hz (i.e., greater alpha activity shortened LRD). Causality of alpha activity dynamics was implied by its temporal precedence over changes of slope. A model where power-law fluctuations of the alpha envelope inhibit baseline activity closely replicated our results. Thus, alpha oscillations may provide an active control mechanism to adaptively regulate LRD of brain activity at slow temporal scales, thereby shaping internal states and cognitive processes.SIGNIFICANCE STATEMENT The two prominent features of ongoing brain activity are oscillations and temporal long-range dependence. Both shape behavioral performance, but little is known about their interaction. Here, we demonstrate such an interaction in EEG and MEG recordings of task-free human brain activity. Specifically, we show that spontaneous dynamics in alpha activity explain ensuing variations of dependence in the low and ultra-low-frequency range. In modeling, two features of alpha oscillations are critical to account for the observed effects on long-range dependence, scale-free properties of alpha oscillations themselves, and a modulation of baseline levels, presumably inhibitory. Both these properties have been observed empirically, and our study hence establishes alpha oscillations as a regulatory mechanism governing long range dependence or "memory" in slow ongoing brain activity. PMID- 29167404 TI - A Critical Role for Dopamine D5 Receptors in Pain Chronicity in Male Mice. AB - Dopaminergic modulation of spinal cord plasticity has long been recognized, but circuits affected by this system and the precise receptor subtypes involved in this modulation have not been defined. Dopaminergic modulation from the A11 nucleus of the hypothalamus contributes to plasticity in a model of chronic pain called hyperalgesic priming. Here we tested the hypothesis that the key receptor subtype mediating this effect is the D5 receptor (D5R). We find that a spinally directed lesion of dopaminergic neurons reverses hyperalgesic priming in both sexes and that a D1/D5 antagonist transiently inhibits neuropathic pain. We used mice lacking D5Rs (DRD5KO mice) to show that carrageenan, interleukin 6, as well as BDNF-induced hyperalgesia and priming are reduced specifically in male mice. These male DRD5KO mice also show reduced formalin pain responses and decreased heat pain. To characterize the subtypes of dorsal horn neurons engaged by dopamine signaling in the hyperalgesic priming model, we used c-fos labeling. We find that a mixed D1/D5 agonist given spinally to primed mice activates a subset of neurons in lamina III and IV of the dorsal horn that coexpress PAX2, a transcription factor for GABAergic interneurons. In line with this, we show that gabazine, a GABA-A receptor antagonist, is antihyperalgesic in primed mice exposed to spinal administration of a D1/D5 agonist. Therefore, the D5R, in males, and the D1R, in females, exert a powerful influence over spinal cord circuitry in pathological pain likely via modulation of deep dorsal horn GABAergic neurons.SIGNIFICANCE STATEMENT Pain is the most prominent reason why people seek medical attention, and chronic pain incidence worldwide has been estimated to be as high as 33%. This study provides new insight into how descending dopamine controls pathological pain states. Our work demonstrates that dopaminergic spinal projections are necessary for the maintenance of a chronic pain state in both sexes; however, D5 receptors seem to play a critical role in males whereas females rely more heavily on D1 receptors, an effect that could be explained by sexual dimorphisms in receptor expression levels. Collectively, our work provides new insights into how the dopaminergic system interacts with spinal circuits to promote pain plasticity. PMID- 29167405 TI - The Microtubule-Associated Protein Tau Mediates the Organization of Microtubules and Their Dynamic Exploration of Actin-Rich Lamellipodia and Filopodia of Cortical Growth Cones. AB - Proper organization and dynamics of the actin and microtubule (MT) cytoskeleton are essential for growth cone behaviors during axon growth and guidance. The MT associated protein tau is known to mediate actin/MT interactions in cell-free systems but the role of tau in regulating cytoskeletal dynamics in living neurons is unknown. We used cultures of cortical neurons from postnatal day (P)0-P2 golden Syrian hamsters (Mesocricetus auratus) of either sex to study the role of tau in the organization and dynamics of the axonal growth cone cytoskeleton. Here, using super resolution microscopy of fixed growth cones, we found that tau colocalizes with MTs and actin filaments and is also located at the interface between actin filament bundles and dynamic MTs in filopodia, suggesting that tau links these two cytoskeletons. Live cell imaging in concert with shRNA tau knockdown revealed that reducing tau expression disrupts MT bundling in the growth cone central domain, misdirects trajectories of MTs in the transition region and prevents single dynamic MTs from extending into growth cone filopodia along actin filament bundles. Rescue experiments with human tau expression restored MT bundling, MT penetration into the growth cone periphery and close MT apposition to actin filaments in filopodia. Importantly, we found that tau knockdown reduced axon outgrowth and growth cone turning in Wnt5a gradients, likely due to disorganized MTs that failed to extend into the peripheral domain and enter filopodia. These results suggest an important role for tau in regulating cytoskeletal organization and dynamics during growth cone behaviors.SIGNIFICANCE STATEMENT Growth cones are the motile tips of growing axons whose guidance behaviors require interaction of the dynamic actin and microtubule cytoskeleton. Tau is a microtubule-associated protein that stabilizes microtubules in neurons and in cell-free systems regulates actin-microtubule interaction. Here, using super resolution microscopy, live-cell imaging, and tau knockdown, we show for the first time in living axonal growth cones that tau is important for microtubule bundling and microtubule exploration of the actin-rich growth cone periphery. Importantly tau knockdown reduced axon outgrowth and growth cone turning, due to disorganized microtubules that fail to enter filopodia and co-align with actin filaments. Understanding normal tau functions will be important for identifying mechanisms of tau in neurodegenerative diseases such as Alzheimer's. PMID- 29167406 TI - Inverted Encoding Models of Human Population Response Conflate Noise and Neural Tuning Width. AB - Channel-encoding models offer the ability to bridge different scales of neuronal measurement by interpreting population responses, typically measured with BOLD imaging in humans, as linear sums of groups of neurons (channels) tuned for visual stimulus properties. Inverting these models to form predicted channel responses from population measurements in humans seemingly offers the potential to infer neuronal tuning properties. Here, we test the ability to make inferences about neural tuning width from inverted encoding models. We examined contrast invariance of orientation selectivity in human V1 (both sexes) and found that inverting the encoding model resulted in channel response functions that became broader with lower contrast, thus apparently violating contrast invariance. Simulations showed that this broadening could be explained by contrast-invariant single-unit tuning with the measured decrease in response amplitude at lower contrast. The decrease in response lowers the signal-to-noise ratio of population responses that results in poorer population representation of orientation. Simulations further showed that increasing signal to noise makes channel response functions less sensitive to underlying neural tuning width, and in the limit of zero noise will reconstruct the channel function assumed by the model regardless of the bandwidth of single units. We conclude that our data are consistent with contrast-invariant orientation tuning in human V1. More generally, our results demonstrate that population selectivity measures obtained by encoding models can deviate substantially from the behavior of single units because they conflate neural tuning width and noise and are therefore better used to estimate the uncertainty of decoded stimulus properties.SIGNIFICANCE STATEMENT It is widely recognized that perceptual experience arises from large populations of neurons, rather than a few single units. Yet, much theory and experiment have examined links between single units and perception. Encoding models offer a way to bridge this gap by explicitly interpreting population activity as the aggregate response of many single neurons with known tuning properties. Here we use this approach to examine contrast-invariant orientation tuning of human V1. We show with experiment and modeling that due to lower signal to noise, contrast-invariant orientation tuning of single units manifests in population response functions that broaden at lower contrast, rather than remain contrast-invariant. These results highlight the need for explicit quantitative modeling when making a reverse inference from population response profiles to single-unit responses. PMID- 29167407 TI - Dissociable Decoding of Spatial Attention and Working Memory from EEG Oscillations and Sustained Potentials. AB - In human scalp EEG recordings, both sustained potentials and alpha-band oscillations are present during the delay period of working memory tasks and may therefore reflect the representation of information in working memory. However, these signals may instead reflect support mechanisms rather than the actual contents of memory. In particular, alpha-band oscillations have been tightly tied to spatial attention and may not reflect location-independent memory representations per se. To determine how sustained and oscillating EEG signals are related to attention and working memory, we attempted to decode which of 16 orientations was being held in working memory by human observers (both women and men). We found that sustained EEG activity could be used to decode the remembered orientation of a stimulus, even when the orientation of the stimulus varied independently of its location. Alpha-band oscillations also carried clear information about the location of the stimulus, but they provided little or no information about orientation independently of location. Thus, sustained potentials contain information about the object properties being maintained in working memory, consistent with previous evidence of a tight link between these potentials and working memory capacity. In contrast, alpha-band oscillations primarily carry location information, consistent with their link to spatial attention.SIGNIFICANCE STATEMENT Working memory plays a key role in cognition, and working memory is impaired in several neurological and psychiatric disorders. Previous research has suggested that human scalp EEG recordings contain signals that reflect the neural representation of information in working memory. However, to conclude that a neural signal actually represents the object being remembered, it is necessary to show that the signal contains fine-grained information about that object. Here, we show that sustained voltages in human EEG recordings contain fine-grained information about the orientation of an object being held in memory, consistent with a memory storage signal. PMID- 29167408 TI - Conjugated linoleic acid prevents age-dependent neurodegeneration in a mouse model of neuropsychiatric lupus via the activation of an adaptive response. AB - Oxidative stress is a key mediator of autoimmune/neurodegenerative disorders. The antioxidant/anti-inflammatory effect of a synthetic conjugated linoleic acid (CLA) mixture in MRL/MpJ-Fas lpr mice (MRL/lpr), an animal model of neuropsychiatric lupus, was previously associated with the improvement of nuclear factor-E2-related factor 2 (Nrf2) defenses in the spleen and liver. However, little is known about the neuroprotective ability of a CLA mixture. This study investigated the age-dependent progression of oxidative stress and the hyperactivation of redox-sensitive compensatory pathways (macroautophagy, Nrf2) in old/diseased MRL/lpr mice brains and examines the effect produced by dietary CLA supplementation. Disrupted redox homeostasis was evidenced in the blood, liver, and brain of 21- to 22-week-old MRL/lpr (Old) mice compared with 8- to 10 week-old MRL/lpr (Young) animals. This alteration was associated with significant hyperactivation of compensatory mechanisms (macroautophagy, Nrf2, and astrocyte activation) in the brains of Old mice. Five-week daily supplementation with CLA (650 mg/kg-1 body weight) of 16-week-old (CLA+Old) mice diminished all the pathological hallmarks at a level comparable to Young mice or healthy controls (BALB/c). Such data demonstrated that MRL/lpr mice can serve as a valuable model for the evaluation of the effectiveness of neuroprotective drugs. Notably, the preventive effect provided by CLA supplementation against age-associated neuronal damage and hyperactivation of compensatory mechanisms suggests that the activation of an adaptive response is at least in part accountable for its neuroprotective ability. PMID- 29167410 TI - Molecular mechanisms underlying catalytic activity of delta 6 desaturase from Glossomastix chrysoplasta and Thalassiosira pseudonana. AB - Delta 6 desaturase (FADS2) is a critical bifunctional enzyme required for PUFA biosynthesis. In some organisms, FADS2s have high substrate specificity, whereas in others, they have high catalytic activity. Previously, we analyzed the molecular mechanisms underlying high FADS2 substrate specificity; in this study, we assessed those underlying the high catalytic activity of FADS2s from Glossomastix chrysoplasta and Thalassiosira pseudonana To understand the structural basis of this catalytic activity, GcFADS2 and TpFADS2 sequences were divided into nine sections, and a domain-swapping approach was applied to examine the role of each section in facilitating the catalytic activity of the overall protein. The results revealed two regions essential to this process: one that extends from the end of the fourth to the beginning of the fifth cytoplasmic transmembrane domain, and another that includes the C-terminal region that occurs after the sixth cytoplasmic transmembrane domain. Based on the domain-swapping analyses, the amino acid residues at ten sites were identified to differ between the GcFADS2 and TpFADS2 sequences, and therefore further analyzed by site directed mutagenesis. T302V, S322A, Y375F, and M384S/M385 substitutions in TpFADS2 significantly affected FADS2 catalytic efficiency. This study offers a solid basis for in-depth understanding of catalytic efficiency of FADS2. PMID- 29167409 TI - Sphingosine 1-phosphate activation of ERM contributes to vascular calcification. AB - Vascular calcification is the deposition of mineral in the artery wall by vascular smooth muscle cells (VSMCs) in response to pathological stimuli. The process is similar to bone formation and is an independent risk factor for cardiovascular disease. Given that ceramide and sphingosine 1-phosphate (S1P) are involved in cardiovascular pathophysiology and biomineralization, their role in VSMC matrix mineralization was investigated. During phosphate-induced VSMC mineralization, endogenous S1P levels increased accompanied by increased sphingosine kinase (SK) activity and increased mRNA expression of SK1 and SK2. Consistent with this, mineralization was increased by exogenous S1P, but decreased by C2-ceramide. Mechanistically, exogenous S1P stimulated ezrin-radixin moesin (ERM) phosphorylation in VSMCs and ERM phosphorylation was increased concomitantly with endogenous S1P during mineralization. Moreover, inhibition of acid sphingomyelinase and ceramidase with desipramine prevented increased S1P levels, ERM activation, and mineralization. Finally, pharmacological inhibition of ERM phosphorylation with NSC663894 decreased mineralization induced by phosphate and exogenous S1P. Although further studies will be needed to verify these findings in vivo, this study defines a novel role for the SK-S1P-ERM pathways in phosphate-induced VSMC matrix mineralization and shows that blocking these pathways with pharmacological inhibitors reduces mineralization. These results may inform new therapeutic approaches to inhibit or delay vascular calcification. PMID- 29167411 TI - 2-Chlorofatty acids induce Weibel-Palade body mobilization. AB - Endothelial dysfunction is a hallmark of multiple inflammatory diseases. Leukocyte interactions with the endothelium have significant effects on vascular wall biology and pathophysiology. Myeloperoxidase (MPO)-derived oxidant products released from leukocytes are potential mediators of inflammation and endothelial dysfunction. 2-Chlorofatty acids (2-ClFAs) are produced as a result of MPO derived HOCl targeting plasmalogen phospholipids. Chlorinated lipids have been shown to be associated with multiple inflammatory diseases, but their impact on surrounding endothelial cells has not been examined. This study tested the biological properties of the 2-ClFA molecular species 2-chlorohexadecanoic acid (2-ClHA) on endothelial cells. A synthetic alkyne analog of 2-ClHA, 2 chlorohexadec-15-ynoic acid (2-ClHyA), was used to examine the subcellular localization of 2-ClFA in human coronary artery endothelial cells. Click chemistry experiments revealed that 2-ClHyA localizes to Weibel-Palade bodies. 2 ClHA and 2-ClHyA promote the release of P-selectin, von Willebrand factor, and angiopoietin-2 from endothelial cells. Functionally, 2-ClHA and 2-ClHyA cause neutrophils to adhere to and platelets to aggregate on the endothelium, as well as increase permeability of the endothelial barrier which has been tied to the release of angiopoietin-2. These findings suggest that 2-ClFAs promote endothelial cell dysfunction, which may lead to broad implications in inflammation, thrombosis, and blood vessel stability. PMID- 29167412 TI - PEMT, Delta6 desaturase, and palmitoyldocosahexaenoyl phosphatidylcholine are increased in rats during pregnancy. AB - DHA is important for fetal neurodevelopment. During pregnancy, maternal plasma DHA increases, but the mechanism is not fully understood. Using rats fed a fixed formula diet (DHA as 0.07% total energy), plasma and liver were collected for fatty acid profiling before pregnancy, at 15 and 20 days of pregnancy, and 7 days postpartum. Phosphatidylethanolamine methyltransferase (PEMT) and enzymes involved in PUFA synthesis were examined in liver. Ad hoc transcriptomic and lipidomic analyses were also performed. With pregnancy, DHA increased in liver and plasma lipids, with a large increase in plasma DHA between day 15 and day 20 that was mainly attributed to an increase in 16:0/DHA phosphatidylcholine (PC) in liver (2.6-fold) and plasma (3.9-fold). Increased protein levels of Delta6 desaturase (FADS2) and PEMT at day 20 and increased Pemt expression and PEMT activity at day 15 suggest that during pregnancy, both DHA synthesis and 16:0/DHA PC synthesis are upregulated. Transcriptomic analysis revealed minor changes in the expression of genes related to phospholipid synthesis, but little insight on DHA metabolism. Hepatic PEMT appears to be the mechanism for increased plasma 16:0/DHA PC, which is supported by increased DHA biosynthesis based on increased FADS2 protein levels. PMID- 29167414 TI - Biomarkers related to respiratory symptoms and lung function in adults with asthma. AB - BACKGROUND: There is a need for easily measurable biomarkers that are able to identify different levels of asthma severity. AIM: To assess the association between peripheral blood cell counts, fractional nitric oxide in exhaled air (FeNO), urinary biomarkers of oxidative stress (8-hydroxy-2'-deoxyguanosine and 8 isoprostane), and asthma severity in adult patients from the general population. METHODS: In the Gene Environment Interactions in Respiratory Diseases study, 287 subjects with asthma (aged 20-64) were identified from the general population in Verona (Italy) (2008-2010). Self-reported asthma attacks, asthma-like symptoms and the use of hospital services in the past year were synthesized in a score of respiratory symptoms (SRS). The association of biomarkers with SRS and lung function measures (pre-bronchodilator FEV1% predicted and FEV1/FVC) was assessed using quasi-Poisson and Gaussian regression models, respectively. RESULTS: Eosinophils (ratio of expected scores: RES[95%CI] = 1.19[1.09,1.30]), basophils (RES[95%CI] = 1.24[1.10,1.40]), lymphocytes (RES[95%CI] = 1.27[1.12,1.45]) and FeNO (RES[95%CI] = 1.18[1.02,1.37]) were positively associated with SRS. However, only eosinophils (RES[95%CI] = 1.15[1.02,1.30]) and lymphocytes (RES[95%CI] = 1.25[1.06,1.47]) showed an independent association. Furthermore, eosinophils (change in the expected outcome for 1-SD increase: CEO[95%CI] = -1.18[-2.09, 0.27]%), basophils (CEO[95%CI] = -1.24[-2.16, -0.33]%) and lymphocytes (CEO[95%CI] = -1.07[-1.99, -0.14]%) were individually, but not independently, associated with FEV1/FVC. Finally, neutrophils were negatively associated with FEV1% predicted (CEO[95%CI] = -2.22[-4.00, -0.44]%). CONCLUSIONS: We identified a pattern of association between a set of biomarkers and asthma endotypes in adult patients from the general population, which could improve understanding of the heterogeneity and severity of the disease and could be useful in defining targeted therapeutic approaches.

AB - Recent studies have highlighted the role of palmitoleic acid [16:1n-7 (cis-9 hexadecenoic acid)] as a lipid hormone that coordinates cross-talk between liver and adipose tissue and exerts anti-inflammatory protective effects on hepatic steatosis and insulin signaling in murine models of metabolic disease. More recently, a 16:1n-7 isomer, cis-7-hexadecenoic acid (16:1n-9), that also possesses marked anti-inflammatory effects, has been described in human circulating monocytes and monocyte-derived macrophages. By using gas chromatographic/mass spectrometric analyses of dimethyl disulfide derivatives of fatty acyl methyl esters, we describe in this study the presence of a third 16:1 isomer, sapienic acid [16:1n-10 (6-cis-hexadecenoic acid)], in phagocytic cells. Cellular levels of 16:1n-10 appear to depend not only on the cellular content of linoleic acid, but also on the expression level of fatty acid desaturase 2, thus revealing a complex regulation both at the enzyme level, via fatty acid substrate competition, and directly at the gene level. However, unlike 16:1n-7 and 16:1n-9, 16:1n-10 levels are not regulated by the activation state of the cell. Moreover, while 16:1n-7 and 16:1n-9 manifest strong anti-inflammatory activity when added to the cells at low concentrations (10 MUM), notably higher concentrations of 16:1n-10 are required to observe a comparable effect. Collectively, these results suggest the presence in phagocytic cells of an unexpected variety of 16:1 isomers, which can be distinguished on the basis of their biological activity and cellular regulation. PMID- 29167415 TI - Ticagrelor Leads to Statin-Induced Rhabdomyolysis: A Case Report. AB - BACKGROUND Following acute coronary intervention in cardiology patients, the combined medical therapy with the platelet inhibitory drug ticagrelor and a statin medication (e.g., simvastatin) is recommended according to international guidelines. Yet combined therapeutic regimens have the potential of pharmacological interaction with both ticagrelor and simvastatin being metabolized by CYP3A4. Rhabdomyolysis is a known side-effect of statin therapy and combined therapy increases the susceptibility to this complication. CASE REPORT A 72-year-old patient presented to our Emergency Department with typical signs of rhabdomyolysis consisting of muscular cramps and pain in both legs and a significant elevation of creatinine kinase (CK). Five months prior to this presentation, he had been hospitalized due to acute coronary syndrome followed by a coronary intervention of a high-grade left anterior descending artery stenosis. His long-term medication included simvastatin 20 mg daily, which he had taken for several years, and ticagrelor, which had been added to his medication following coronary intervention. The patient showed fast recovery of symptoms and rapid normalization of CK levels upon treatment change from ticagrelor to clopidogrel with a paused statin administration. CONCLUSIONS The combined use of ticagrelor with low dose simvastatin poses a risk for rhabdomyolysis even in patients with normal kidney function. Patients treated with ticagrelor might require changes in statin therapy and dose adjustments in order to avoid pharmacological interactions and higher risk for adverse effects. PMID- 29167416 TI - Second-Look Arthroscopic Evaluation and Clinical Outcomes of Anatomic Anterior Cruciate Ligament Reconstruction with Autograft and Hybrid Graft: A Retrospective Study. AB - BACKGROUND Graft choice is very controversial. This study compared the second look evaluation and clinical outcomes of anatomic ACL-R using a thin autograft versus a thick hybrid graft. MATERIAL AND METHODS Sixty-eight patients who had received ACL-R with hamstring autograft or autograft-allograft hybrid graft accepted second-look arthroscopy were grouped (autograft: n=31, age: 32.8+/-8.9, Male/Female: 16/15, and hybrid graft: n=37, age: 33.9+/-8.4, Male/Female: 27/10). Patients were evaluated with the functional score and KT-1000 test before reconstruction. The re-examination and second-look evaluation were performed at 2 year follow-up. Results were compared and further comparisons were made for grafts size >8.5 mm. RESULTS The hybrid group showed thicker graft size and bigger graft occupancy (9.0+/-0.5 mm vs. 8.5+/-0.7 mm, P=.003; 80.1+/-7.0% vs. 69.9+/-6.9%, P8.5 mm were selected and compared (autograft, n=16; hybrid, n=29). Graft tension and Synovial coverage showed a significant difference (P=.036 and P=.029). The Lysholm, IKDC, and KT-1000 test were significantly superior for the autograft than the hybrid graft (P=.036, P=.004, and P=.003, respectively). CONCLUSIONS A pure autograft is superior to a hybrid graft with same diameter in ACL-R because the augmenting allografts may be null and void. Therefore, a homogenous graft is recommended. PMID- 29167417 TI - Loss-of-activity-mutation in the cardiac chloride-bicarbonate exchanger AE3 causes short QT syndrome. AB - Patients with short QT syndrome (SQTS) may present with syncope, ventricular fibrillation or sudden cardiac death. Six SQTS susceptibility genes, encoding cation channels, explain <25% of SQTS cases. Here we identify a missense mutation in the anion exchanger (AE3)-encoding SLC4A3 gene in two unrelated families with SQTS. The mutation causes reduced surface expression of AE3 and reduced membrane bicarbonate transport. Slc4a3 knockdown in zebrafish causes increased cardiac pHi, short QTc, and reduced systolic duration, which is rescued by wildtype but not mutated SLC4A3. Mechanistic analyses suggest that an increase in pHi and decrease in [Cl-]i shortened the action potential duration. However, other mechanisms may also play a role. Altered anion transport represents a mechanism for development of arrhythmia and may provide new therapeutic possibilities. PMID- 29167418 TI - Skyrmion dynamics in a frustrated ferromagnetic film and current-induced helicity locking-unlocking transition. AB - The helicity-orbital coupling is an intriguing feature of magnetic skyrmions in frustrated magnets. Here we explore the skyrmion dynamics in a frustrated magnet based on the J 1-J 2-J 3 classical Heisenberg model explicitly by including the dipole-dipole interaction. The skyrmion energy acquires a helicity dependence due to the dipole-dipole interaction, resulting in the current-induced translational motion with a fixed helicity. The lowest-energy states are the degenerate Bloch type states, which can be used for building the binary memory. By increasing the driving current, the helicity locking-unlocking transition occurs, where the translational motion changes to the rotational motion. Furthermore, we demonstrate that two skyrmions can spontaneously form a bound state. The separation of the bound state forced by a driving current is also studied. In addition, we show the annihilation of a pair of skyrmion and antiskyrmion. Our results reveal the distinctive frustrated skyrmions may enable viable applications in topological magnetism. PMID- 29167419 TI - Widespread theta synchrony and high-frequency desynchronization underlies enhanced cognition. AB - The idea that synchronous neural activity underlies cognition has driven an extensive body of research in human and animal neuroscience. Yet, insufficient data on intracranial electrical connectivity has precluded a direct test of this hypothesis in a whole-brain setting. Through the lens of memory encoding and retrieval processes, we construct whole-brain connectivity maps of fast gamma (30 100 Hz) and slow theta (3-8 Hz) spectral neural activity, based on data from 294 neurosurgical patients fitted with indwelling electrodes. Here we report that gamma networks desynchronize and theta networks synchronize during encoding and retrieval. Furthermore, for nearly all brain regions we studied, gamma power rises as that region desynchronizes with gamma activity elsewhere in the brain, establishing gamma as a largely asynchronous phenomenon. The abundant phenomenon of theta synchrony is positively correlated with a brain region's gamma power, suggesting a predominant low-frequency mechanism for inter-regional communication.

PMID- 29167422 TI - Full-wave modeling of broadband near field scanning microwave microscopy. AB - A three-dimensional finite element numerical modeling for the scanning microwave microscopy (SMM) setup is applied to study the full-wave quantification of the local material properties of samples. The modeling takes into account the radiation and scattering losses of the nano-sized probe neglected in previous models based on low-frequency assumptions. The scanning techniques of approach curves and constant height are implemented. In addition, we conclude that the SMM has the potential for use as a broadband dielectric spectroscopy operating at higher frequencies up to THz. The results demonstrate the accuracy of previous models. We draw conclusions in light of the experimental results. PMID- 29167421 TI - Structural insights into substrate and inhibitor binding sites in human indoleamine 2,3-dioxygenase 1. AB - Human indoleamine 2,3-dioxygenase 1 (hIDO1) is an attractive cancer immunotherapeutic target owing to its role in promoting tumoral immune escape. However, drug development has been hindered by limited structural information. Here, we report the crystal structures of hIDO1 in complex with its substrate, Trp, an inhibitor, epacadostat, and/or an effector, indole ethanol (IDE). The data reveal structural features of the active site (Sa) critical for substrate activation; in addition, they disclose a new inhibitor-binding mode and a distinct small molecule binding site (Si). Structure-guided mutation of a critical residue, F270, to glycine perturbs the Si site, allowing structural determination of an inhibitory complex, where both the Sa and Si sites are occupied by Trp. The Si site offers a novel target site for allosteric inhibitors and a molecular explanation for the previously baffling substrate-inhibition behavior of the enzyme. Taken together, the data open exciting new avenues for structure-based drug design. PMID- 29167423 TI - Reassessment of chitosanase substrate specificities and classification. AB - Chitosanases can be used to produce partially acetylated chitosan oligosaccharides (paCOS) for different applications, provided they are thoroughly characterized. However, recent studies indicate that the established classification system for chitosanases is too simplistic. Here, we apply a highly sensitive method for quantitatively sequencing paCOS to reassess the substrate specificities of the best-characterized class I-III chitosanases. The enzymes' abilities to cleave bonds at GlcNAc residues positioned at subsite (-1) or (+1), on which the classification system is based, vary especially when the substrates have different fractions of acetylation (F A ). Conflicts with the recent classification are observed at higher F A , which were not investigated in prior specificity determinations. Initial analyses of pectin-degrading enzymes reveal that classifications of other polysaccharide-degrading enzymes should also be critically reassessed. Based on our results, we tentatively suggest a chitosanase classification system which is based on specificities and preferences of subsites (-2) to (+2). PMID- 29167424 TI - MiR-92a and miR-486 are potential diagnostic biomarkers for mercury poisoning and jointly sustain NF-kappaB activity in mercury toxicity. AB - Occupational and environmental exposure to mercury is a public health concern worldwide. Although the altered epigenetic regulatory features, such as microRNA, have been associated with mercury exposure, the underlying molecular mechanism is not well illuminated. This study aimed to confirm that hsa-miR-92a and hsa-miR 486 are novel diagnostic biomarkers of occupational mercury poisoning, and to explore the underlying mechanism of miR-92a and miR-486 in mercury toxicity. RT qPCR assays and receiver operating characteristics curve analyses were conducted to confirm the diagnostic value of miR-92a and miR-486 as biomarkers of occupational mercury poisoning. Dual-luciferase assay was applied to confirm the target gene of miR-92a and miR-486 in vitro. Then, we established an in-vitro model where miR-92a and miR-486 were overexpressed or knocked down in HEK-293 and HUVEC cells. RT-qPCR and western blotting were used to analyze gene and protein expression levels. Cell apoptosis was determined by flow cytometry. Results show that miR-92a and miR-486 expression levels were up-regulated in workers exposed to occupational mercury. Upregulation of miR-92a and miR-486 may play a crucial role in mercury toxicity by jointly activating the NF-kappaB signaling pathway via targeting KLF4 and Cezanne, respectively. PMID- 29167425 TI - Experimentally simulating the dynamics of quantum light and matter at deep-strong coupling. AB - The quantum Rabi model describing the fundamental interaction between light and matter is a cornerstone of quantum physics. It predicts exotic phenomena like quantum phase transitions and ground-state entanglement in ultrastrong and deep strong coupling regimes, where coupling strengths are comparable to or larger than subsystem energies. Demonstrating dynamics remains an outstanding challenge, the few experiments reaching these regimes being limited to spectroscopy. Here, we employ a circuit quantum electrodynamics chip with moderate coupling between a resonator and transmon qubit to realise accurate digital quantum simulation of deep-strong coupling dynamics. We advance the state of the art in solid-state digital quantum simulation by using up to 90 second-order Trotter steps and probing both subsystems in a combined Hilbert space dimension of ~80, demonstrating characteristic Schrodinger-cat-like entanglement and large photon build-up. Our approach will enable exploration of extreme coupling regimes and quantum phase transitions, and demonstrates a clear first step towards larger complexities such as in the Dicke model. PMID- 29167426 TI - Epigenetic targeting of bromodomain protein BRD4 counteracts cancer cachexia and prolongs survival. AB - Cancer cachexia is a devastating metabolic syndrome characterized by systemic inflammation and massive muscle and adipose tissue wasting. Although it is responsible for approximately one-third of cancer deaths, no effective therapies are available and the underlying mechanisms have not been fully elucidated. We previously identified the bromodomain and extra-terminal domain (BET) protein BRD4 as an epigenetic regulator of muscle mass. Here we show that the pan-BET inhibitor (+)-JQ1 protects tumor-bearing mice from body weight loss and muscle and adipose tissue wasting. Remarkably, in C26-tumor-bearing mice (+)-JQ1 administration dramatically prolongs survival, without directly affecting tumor growth. By ChIP-seq and ChIP analyses, we unveil that BET proteins directly promote the muscle atrophy program during cachexia. In addition, BET proteins are required to coordinate an IL6-dependent AMPK nuclear signaling pathway converging on FoxO3 transcription factor. Overall, these findings indicate that BET proteins may represent a promising therapeutic target in the management of cancer cachexia. PMID- 29167429 TI - Non-universal transmission phase behaviour of a large quantum dot. AB - The electron wave function experiences a phase modification at coherent transmission through a quantum dot. This transmission phase undergoes a characteristic shift of pi when scanning through a Coulomb blockade resonance. Between successive resonances either a transmission phase lapse of pi or a phase plateau is theoretically expected to occur depending on the parity of quantum dot states. Despite considerable experimental effort, this transmission phase behaviour has remained elusive for a large quantum dot. Here we report on transmission phase measurements across such a large quantum dot hosting hundreds of electrons. Scanning the transmission phase along 14 successive resonances with an original two-path interferometer, we observe both phase lapses and plateaus. We demonstrate that quantum dot deformation alters the sequence of phase lapses and plateaus via parity modifications of the involved quantum dot states. Our findings set a milestone towards an comprehensive understanding of the transmission phase of quantum dots. PMID- 29167428 TI - Low pH-induced conformational change and dimerization of sortilin triggers endocytosed ligand release. AB - Low pH-induced ligand release and receptor recycling are important steps for endocytosis. The transmembrane protein sortilin, a beta-propeller containing endocytosis receptor, internalizes a diverse set of ligands with roles in cell differentiation and homeostasis. The molecular mechanisms of pH-mediated ligand release and sortilin recycling are unresolved. Here we present crystal structures that show the sortilin luminal segment (s-sortilin) undergoes a conformational change and dimerizes at low pH. The conformational change, within all three sortilin luminal domains, provides an altered surface and the dimers sterically shield a large interface while bringing the two s-sortilin C-termini into close proximity. Biophysical and cell-based assays show that members of two different ligand families, (pro)neurotrophins and neurotensin, preferentially bind the sortilin monomer. This indicates that sortilin dimerization and conformational change discharges ligands and triggers recycling. More generally, this work may reveal a double mechanism for low pH-induced ligand release by endocytosis receptors. PMID- 29167427 TI - Scallop genome reveals molecular adaptations to semi-sessile life and neurotoxins. AB - Bivalve molluscs are descendants of an early-Cambrian lineage superbly adapted to benthic filter feeding. Adaptations in form and behavior are well recognized, but the underlying molecular mechanisms are largely unknown. Here, we investigate the genome, various transcriptomes, and proteomes of the scallop Chlamys farreri, a semi-sessile bivalve with well-developed adductor muscle, sophisticated eyes, and remarkable neurotoxin resistance. The scallop's large striated muscle is energy dynamic but not fully differentiated from smooth muscle. Its eyes are supported by highly diverse, intronless opsins expanded by retroposition for broadened spectral sensitivity. Rapid byssal secretion is enabled by a specialized foot and multiple proteins including expanded tyrosinases. The scallop uses hepatopancreas to accumulate neurotoxins and kidney to transform to high-toxicity forms through expanded sulfotransferases, probably as deterrence against predation, while it achieves neurotoxin resistance through point mutations in sodium channels. These findings suggest that expansion and mutation of those genes may have profound effects on scallop's phenotype and adaptation. PMID- 29167430 TI - Short-term reward experience biases inference despite dissociable neural correlates. AB - Optimal decision-making employs short-term rewards and abstract long-term information based on which of these is deemed relevant. Employing short- vs. long term information is associated with different learning mechanisms, yet neural evidence showing that these two are dissociable is lacking. Here we demonstrate that long-term, inference-based beliefs are biased by short-term reward experiences and that dissociable brain regions facilitate both types of learning. Long-term inferences are associated with dorsal striatal and frontopolar cortex activity, while short-term rewards engage the ventral striatum. Stronger concurrent representation of reward signals by mediodorsal striatum and frontopolar cortex correlates with less biased, more optimal individual long-term inference. Moreover, dynamic modulation of activity in a cortical cognitive control network and the medial striatum is associated with trial-by-trial control of biases in belief updating. This suggests that counteracting the processing of optimally to-be-ignored short-term rewards and cortical suppression of associated reward-signals, determines long-term learning success and failure. PMID- 29167431 TI - Fabrication and Verification of Conjugated AuNP-Antibody Nanoprobe for Sensitivity Improvement in Electrochemical Biosensors. AB - This study was designed to obtain covalently coupled conjugates as means for achieving higher stability and better coverage of the AuNPs by antibodies on the particle surface suitable for sensor performance enhancement. Starting by using a modified protocol, colloid gold solution, with mean AuNP core size of ~6 nm was synthesized. The protocol used for conjugation of AuNPs to osteocalcin antibody in this study relies on covalent and electrostatic attractions between constituents. Varieties of conjugates with varying combinations of crosslinkers and different concentrations were successfully synthesized. The obtained products were characterized and their properties were studied to determine the best candidate in sense of antibody - antigen reactivity. Using AuNP-GSH-NHS-Ab combination (1:1:1), the tertiary structure of the protein was maintained and thus the antibody remained functional in the future steps. This one-pot method provided a simple method for covalently coupling antibodies on the particle surface while keeping their functionality intact. The AuNP content of the solution also accelerated electron transfer rate and thus amplifies the detection signal. With the developed and discussed technique herein, a simple solution is modeled to be used for measuring serum levels of biomarkers in single and/or multiplexed sensor systems. PMID- 29167432 TI - Simultaneous quarter-wave plate and half-mirror operation through a highly flexible single layer anisotropic metasurface. AB - A highly flexible single-layer metasurface manifesting quarter-wave plate as well as half-mirror (1:1 beam-splitter) operation in the microwave frequency regime is being presented in this research. The designed metasurface reflects half power of the impinging linearly polarized electromagnetic wave as circularly polarized wave while the remaining half power is transmitted as circularly polarized wave at resonance frequency. Similarly, a circularly polarized incident wave is reflected and transmitted as linearly polarized wave with equal half powers. Moreover, the response of the metasurface is quite stable against the variations in the incidence angle up to 45 degrees . The measurements performed on the fabricated prototype exhibit a good agreement with the simulation results. The compact size, flexible structure, angular stability and two in one operation (operating as a quarter-wave plate and beam-splitter at the same time) are the main characteristics of the subject metasurface that makes it a potential candidate for numerous applications in communication and miniaturized and conformal polarization control devices. PMID- 29167433 TI - Repeated storage of respired carbon in the equatorial Pacific Ocean over the last three glacial cycles. AB - As the largest reservoir of carbon exchanging with the atmosphere on glacial interglacial timescales, the deep ocean has been implicated as the likely location of carbon sequestration during Pleistocene glaciations. Despite strong theoretical underpinning for this expectation, radiocarbon data on watermass ventilation ages conflict, and proxy interpretations disagree about the depth, origin and even existence of the respired carbon pool. Because any change in the storage of respiratory carbon is accompanied by corresponding changes in dissolved oxygen concentrations, proxy data reflecting oxygenation are valuable in addressing these apparent inconsistencies. Here, we present a record of redox sensitive uranium from the central equatorial Pacific Ocean to identify intervals associated with respiratory carbon storage over the past 350 kyr, providing evidence for repeated carbon storage over the last three glacial cycles. We also synthesise our data with previous work and propose an internally consistent picture of glacial carbon storage and equatorial Pacific Ocean watermass structure. PMID- 29167434 TI - Overweight in patients with chronic obstructive pulmonary disease needs more attention: a cross-sectional study in general practice. AB - Guidelines for management of chronic obstructive pulmonary disease (COPD) primarily focus on the prevention of weight loss, while overweight and obesity are highly prevalent in patients with milder stages of COPD. This cross-sectional study examines the association of overweight and obesity with the prevalence of comorbid disorders and prescribed medication for obstructive airway disease, in patients with mild to moderate COPD. Data were used from electronic health records of 380 Dutch general practices in 2014. In total, we identified 4938 patients with mild or moderate COPD based on spirometry data, and a recorded body mass index (BMI) of >=21 kg/m2. Outcomes in overweight (BMI >= 25 and <30 kg/m2) and obese (BMI >=30 kg/m2) patients with COPD were compared to those with a normal weight (BMI >= 21 and <25 kg/m2), by logistic multilevel analyses. Compared to COPD patients with a normal weight, positive associations were found for diabetes, osteoarthritis, and hypertension, for both overweight (OR: 1.4-1.7) and obese (OR: 2.4-3.8) patients, and for heart failure in obese patients (OR: 2.3). Osteoporosis was less prevalent in overweight (OR: 0.7) and obese (OR: 0.5) patients, and anxiety disorders in obese patients (OR: 0.5). No associations were found for coronary heart disease, stroke, sleep disturbance, depression, and pneumonia. Furthermore, obese patients were in general more often prescribed medication for obstructive airway disease compared to patients with a normal weight. The findings of this study underline the need to increase awareness in general practitioners for excess weight in patients with mild to moderate COPD. PMID- 29167435 TI - Galphai is required for carvedilol-induced beta1 adrenergic receptor beta arrestin biased signaling. AB - The beta1 adrenergic receptor (beta1AR) is recognized as a classical Galphas coupled receptor. Agonist binding not only initiates G protein-mediated signaling but also signaling through the multifunctional adapter protein beta-arrestin. Some betaAR ligands, such as carvedilol, stimulate betaAR signaling preferentially through beta-arrestin, a concept known as beta-arrestin-biased agonism. Here, we identify a signaling mechanism, unlike that previously known for any Galphas-coupled receptor, whereby carvedilol induces the transition of the beta1AR from a classical Galphas-coupled receptor to a Galphai-coupled receptor stabilizing a distinct receptor conformation to initiate beta-arrestin mediated signaling. Recruitment of Galphai is not induced by any other betaAR ligand screened, nor is it required for beta-arrestin-bias activated by the beta2AR subtype of the betaAR family. Our findings demonstrate a previously unrecognized role for Galphai in beta1AR signaling and suggest that the concept of beta-arrestin-bias may need to be refined to incorporate the selective bias of receptors towards distinct G protein subtypes. PMID- 29167436 TI - Elevated blood pressure is associated with higher prevalence of low visual acuity among adolescent males in Northeast China. AB - The purpose of this study is to track the trends of low visual acuity (VA) from 2005 to 2014, and to investigate its associations with systemic blood pressure (BP) components among adolescents in Northeast China. A total of 55320 students of Han nationality aged 13 to 18 years were included. There has been a significant increase in the prevalence of low VA, with 31.3% in 2005, 40.2% in 2010 and 43.4% in 2014. In multivariable-adjusted logistic regression models, each 1-mm Hg increment in systolic BP (SBP) was associated with 0.8% (95% confidence interval [CI]: 0.1-1.6%), 0.5% (95% CI: 0.1-0.9%) and 1.1% (95% CI: 0.6-1.6%) increased odds of low VA for males in 2005, 2010 and 2014; each 1-mm Hg increment in pulse pressure (PP) was associated with 1.6% (95% CI: 0.7-2.5%), 0.8% (95% CI: 0.4-1.2%) and 1.2% (95% CI: 0.7-1.7%) increased odds of low VA. Higher PP categories had greater odds for low VA compared with the reference group. Similar associations were not observed for females. We conclude that higher prevalence of low VA was significantly associated with higher SBP and PP in males. Furthermore, there was a dose-dependent association between the prevalence of low VA and the levels of PP. PMID- 29167437 TI - Structurally triggered metal-insulator transition in rare-earth nickelates. AB - Rare-earth nickelates form an intriguing series of correlated perovskite oxides. Apart from LaNiO3, they exhibit on cooling a sharp metal-insulator electronic phase transition, a concurrent structural phase transition, and a magnetic phase transition toward an unusual antiferromagnetic spin order. Appealing for various applications, full exploitation of these compounds is still hampered by the lack of global understanding of the interplay between their electronic, structural, and magnetic properties. Here we show from first-principles calculations that the metal-insulator transition of nickelates arises from the softening of an oxygen breathing distortion, structurally triggered by oxygen-octahedra rotation motions. The origin of such a rare triggered mechanism is traced back in their electronic and magnetic properties, providing a united picture. We further develop a Landau model accounting for the metal-insulator transition evolution in terms of the rare-earth cations and rationalizing how to tune this transition by acting on oxygen rotation motions. PMID- 29167438 TI - Checkpoint kinase 1 is essential for normal B cell development and lymphomagenesis. AB - Checkpoint kinase 1 (CHK1) is critical for intrinsic cell cycle control and coordination of cell cycle progression in response to DNA damage. Despite its essential function, CHK1 has been identified as a target to kill cancer cells and studies using Chk1 haploinsufficient mice initially suggested a role as tumor suppressor. Here, we report on the key role of CHK1 in normal B-cell development, lymphomagenesis and cell survival. Chemical CHK1 inhibition induces BCL2 regulated apoptosis in primary as well as malignant B-cells and CHK1 expression levels control the timing of lymphomagenesis in mice. Moreover, total ablation of Chk1 in B-cells arrests their development at the pro-B cell stage, a block that, surprisingly, cannot be overcome by inhibition of mitochondrial apoptosis, as cell cycle arrest is initiated as an alternative fate to limit the spread of damaged DNA. Our findings define CHK1 as essential in B-cell development and potent target to treat blood cancer. PMID- 29167439 TI - Eroded telomeres are rearranged in quiescent fission yeast cells through duplications of subtelomeric sequences. AB - While the mechanisms of telomere maintenance has been investigated in dividing cells, little is known about the stability of telomeres in quiescent cells and how dysfunctional telomeres are processed in non-proliferating cells. Here we examine the stability of telomeres in quiescent cells using fission yeast. While wild type telomeres are stable in quiescence, we observe that eroded telomeres were highly rearranged during quiescence in telomerase minus cells. These rearrangements depend on homologous recombination (HR) and correspond to duplications of subtelomeric regions. HR is initiated at newly identified subtelomeric homologous repeated sequences (HRS). We further show that TERRA (Telomeric Repeat-containing RNA) is increased in post-mitotic cells with short telomeres and correlates with telomere rearrangements. Finally, we demonstrate that rearranged telomeres prevent cells to exit properly from quiescence. Taken together, we describe in fission yeast a mode of telomere repair mechanism specific to post-mitotic cells that is likely promoted by transcription. PMID- 29167440 TI - Fusion guide RNAs for orthogonal gene manipulation with Cas9 and Cpf1. AB - The bacteria-derived clustered regularly interspaced short palindromic repeat (CRISPR)-Cas systems are powerful tools for genome engineering. Recently, in addition to Cas protein engineering, the improvement of guide RNAs are also performed, contributing to broadening the research area of CRISPR-Cas9 systems. Here we develop a fusion guide RNA (fgRNA) that functions with both Cas9 and Cpf1 proteins to induce mutations in human cells. Furthermore, we demonstrate that fgRNAs can be used in multiplex genome editing and orthogonal genome manipulation with two types of Cas proteins. Our results show that fgRNAs can be used as a tool for performing multiple gene manipulations. PMID- 29167441 TI - Primer synthesis by a eukaryotic-like archaeal primase is independent of its Fe-S cluster. AB - DNA replication depends on primase, the specialised polymerase responsible for synthesis of the RNA primers that are elongated by the replicative DNA polymerases. In eukaryotic and archaeal replication, primase is a heterodimer of two subunits, PriS and PriL. Recently, a third primase subunit named PriX was identified in the archaeon Sulfolobus solfataricus. PriX is essential for primer synthesis and is structurally related to the Fe-S cluster domain of eukaryotic PriL. Here we show that PriX contains a nucleotide-binding site required for primer synthesis, and demonstrate equivalence of nucleotide-binding residues in PriX with eukaryotic PriL residues that are known to be important for primer synthesis. A primase chimera, where PriX is fused to a truncated version of PriL lacking the Fe-S cluster domain retains wild-type levels of primer synthesis. Our evidence shows that PriX has replaced PriL as the subunit that endows primase with the unique ability to initiate nucleic acid synthesis. Importantly, our findings reveal that the Fe-S cluster is not required for primer synthesis. PMID- 29167442 TI - Combinatorial metabolic engineering using an orthogonal tri-functional CRISPR system. AB - Designing an optimal microbial cell factory often requires overexpression, knock down, and knock-out of multiple gene targets. Unfortunately, such rewiring of cellular metabolism is often carried out sequentially and with low throughput. Here, we report a combinatorial metabolic engineering strategy based on an orthogonal tri-functional CRISPR system that combines transcriptional activation, transcriptional interference, and gene deletion (CRISPR-AID) in the yeast Saccharomyces cerevisiae. This strategy enables perturbation of the metabolic and regulatory networks in a modular, parallel, and high-throughput manner. We demonstrate the application of CRISPR-AID not only to increase the production of beta-carotene by 3-fold in a single step, but also to achieve 2.5-fold improvement in the display of an endoglucanase on the yeast surface by optimizing multiple metabolic engineering targets in a combinatorial manner.

AB - Although the size-frequency distributions of icebergs can provide insight into how they disintegrate, our understanding of this process is incomplete. Fundamentally, there is a discrepancy between iceberg power-law size-frequency distributions observed at glacial calving fronts and lognormal size-frequency distributions observed globally within open waters that remains unexplained. Here we use passive seismic monitoring to examine mechanisms of iceberg disintegration as a function of drift. Our results indicate that the shift in the size-frequency distribution of iceberg sizes observed is a product of fracture-driven iceberg disintegration and dimensional reductions through melting. We suggest that changes in the characteristic size-frequency scaling of icebergs can be explained by the emergence of a dominant set of driving processes of iceberg degradation towards the open ocean. Consequently, the size-frequency distribution required to model iceberg distributions accurately must vary according to distance from the calving front.

AB - Understanding the relationship between spontaneous stochastic fluctuations and the topology of the underlying gene regulatory network is of fundamental importance for the study of single-cell stochastic gene expression. Here by solving the analytical steady-state distribution of the protein copy number in a general kinetic model of stochastic gene expression with nonlinear feedback regulation, we reveal the relationship between stochastic fluctuations and feedback topology at the single-molecule level, which provides novel insights into how and to what extent a feedback loop can enhance or suppress molecular fluctuations. Based on such relationship, we also develop an effective method to extract the topological information of a gene regulatory network from single-cell gene expression data. The theory is demonstrated by numerical simulations and, more importantly, validated quantitatively by single-cell data analysis of a synthetic gene circuit integrated in human kidney cells. PMID- 29167446 TI - Hyperpolarized [1-13C]-acetate Renal Metabolic Clearance Rate Mapping. AB - 11C-acetate is a positron emission tomography (PET) tracer of oxidative metabolism, whereas hyperpolarized 13C-acetate can be used in magnetic resonance imaging (MRI) for investigating specific metabolic processes. The aims of this study were to examine if the kinetic formalism of 11C-acetate PET in the kidneys is comparable to that of 13C-acetate MRI, and to compare the dynamic metabolic information of hyperpolarized 13C-acetate MRI with that obtained with 11C-acetate PET. Rats were examined with dynamic hyperpolarized 13C-acetate MRI or 11C acetate PET before and after intravenous injection of furosemide, a loop diuretic known to alter both the hemodynamics and oxygen consumption in the kidney. The metabolic clearance rates (MCR) were estimated and compared between the two modalities experimentally in vivo and in simulations. There was a clear dependency on the mean transit time and MCR for both 13C-acetate and 11C-acetate following furosemide administration, while no dependencies on the apparent renal perfusion were observed. This study demonstrated that hyperpolarized 13C-acetate MRI is feasible for measurements of the intrarenal energetic demand via the MCR, and that the quantitative measures are correlated with those measured by 11C acetate PET, even though the temporal window is more than 30 times longer with 11C-acetate. PMID- 29167447 TI - Hyperoxidation of ether-linked phospholipids accelerates neutrophil extracellular trap formation. AB - Because neutrophil extracellular trap (NET) formation is involved in the pathology of a wide variety of diseases, NET-regulating compounds are expected to be useful for the therapies of these diseases. In this study, we identified sulfasalazine (SSZ) as a potent enhancer of NET formation both in vitro and in vivo. Although SSZ did not increase the amount of ROS generated, it accelerated the generation of ether-linked oxidized phospholipids, such as PE (18;1e/15-HETE) and PC (16;0e/13-HODE). Trolox, but not 2-ME, effectively suppressed lipid oxidation and NET formation that were induced by SSZ. SSZ is known as a potent inducer of ferroptosis in cancer cells by inhibiting xCT, a component of the cystine transporter. However, we found that SSZ accelerated NET formation in an xCT-independent manner. Structure-activity relationship studies revealed that the sulfapyridine moiety of SSZ plays a central role in enhancing NET formation. Furthermore, we found that two additional sulfonamide and sulfone derivatives possess NET-inducing activity by accelerating lipid oxidation. These results indicate that the hyperoxidation of ether-linked phospholipids is a key mechanism for accelerating NET formation. PMID- 29167448 TI - Systematic Screening of Chemokines to Identify Candidates to Model and Create Ectopic Lymph Node Structures for Cancer Immunotherapy. AB - The induction of ectopic lymph node structures (ELNs) holds great promise to augment immunotherapy against multiple cancers including metastatic melanoma, in which ELN formation has been associated with a unique immune-related gene expression signature composed of distinct chemokines. To investigate the therapeutic potential of ELNs induction, preclinical models of ELNs are needed for interrogation of these chemokines. Computational models provide a non invasive, cost-effective method to investigate leukocyte trafficking in the tumor microenvironment, but parameterizing such models is difficult due to differing assay conditions and contexts among the literature. To better achieve this, we systematically performed microchemotaxis assays on purified immune subsets including human pan-T cells, CD4+ T cells, CD8+ T cells, B cells, and NK cells, with 49 recombinant chemokines using a singular technique, and standardized conditions resulting in a dataset representing 238 assays. We then outline a groundwork computational model that can simulate cellular migration in the tumor microenvironment in response to a chemoattractant gradient created from stromal, lymphoid, or antigen presenting cell interactions. The resulting model can then be parameterized with standardized data, such as the dataset presented here, and demonstrates how a computational approach can help elucidate developing ELNs and their impact on tumor progression. PMID- 29167449 TI - Structure of human immunoproteasome with a reversible and noncompetitive inhibitor that selectively inhibits activated lymphocytes. AB - Proteasome inhibitors benefit patients with multiple myeloma and B cell-dependent autoimmune disorders but exert toxicity from inhibition of proteasomes in other cells. Toxicity should be minimized by reversible inhibition of the immunoproteasome beta5i subunit while sparing the constitutive beta5c subunit. Here we report beta5i-selective inhibition by asparagine-ethylenediamine (AsnEDA) based compounds and present the high-resolution cryo-EM structural analysis of the human immunoproteasome. Despite inhibiting noncompetitively, an AsnEDA inhibitor binds the active site. Hydrophobic interactions are accompanied by hydrogen bonding with beta5i and beta6 subunits. The inhibitors are far more cytotoxic for myeloma and lymphoma cell lines than for hepatocarcinoma or non activated lymphocytes. They block human B-cell proliferation and promote apoptotic cell death selectively in antibody-secreting B cells, and to a lesser extent in activated human T cells. Reversible, beta5i-selective inhibitors may be useful for treatment of diseases involving activated or neoplastic B cells or activated T cells. PMID- 29167451 TI - The role of Atlantic overturning circulation in the recent decline of Atlantic major hurricane frequency. AB - Observed Atlantic major hurricane frequency has exhibited pronounced multidecadal variability since the 1940s. However, the cause of this variability is debated. Using observations and a coupled earth system model (GFDL-ESM2G), here we show that the decline of the Atlantic major hurricane frequency during 2005-2015 is associated with a weakening of the Atlantic Meridional Overturning Circulation (AMOC) inferred from ocean observations. Directly observed North Atlantic sulfate aerosol optical depth has not increased (but shows a modest decline) over this period, suggesting the decline of the Atlantic major hurricane frequency during 2005-2015 is not likely due to recent changes in anthropogenic sulfate aerosols. Instead, we find coherent multidecadal variations involving the inferred AMOC and Atlantic major hurricane frequency, along with indices of Atlantic Multidecadal Variability and inverted vertical wind shear. Our results provide evidence for an important role of the AMOC in the recent decline of Atlantic major hurricane frequency. PMID- 29167450 TI - MafB is a critical regulator of complement component C1q. AB - The transcription factor MafB is expressed by monocytes and macrophages. Efferocytosis (apoptotic cell uptake) by macrophages is important for inhibiting the development of autoimmune diseases, and is greatly reduced in Mafb-deficient macrophages. Here, we show the expression of the first protein in the classical complement pathway C1q is important for mediating efferocytosis and is reduced in Mafb-deficient macrophages. The efferocytosis defect in Mafb-deficient macrophages can be rescued by adding serum from wild-type mice, but not by adding serum from C1q-deficient mice. By hemolysis assay we also show that activation of the classical complement pathway is decreased in Mafb-deficient mice. In addition, MafB overexpression induces C1q-dependent gene expression and signals that induce C1q genes are less effective in the absence of MafB. We also show that Mafb-deficiency can increase glomerular autoimmunity, including anti-nuclear antibody deposition. These results show that MafB is an important regulator of C1q.

PMID- 29167452 TI - Cross continental increase in methane ebullition under climate change. AB - Methane (CH4) strongly contributes to observed global warming. As natural CH4 emissions mainly originate from wet ecosystems, it is important to unravel how climate change may affect these emissions. This is especially true for ebullition (bubble flux from sediments), a pathway that has long been underestimated but generally dominates emissions. Here we show a remarkably strong relationship between CH4 ebullition and temperature across a wide range of freshwater ecosystems on different continents using multi-seasonal CH4 ebullition data from the literature. As these temperature-ebullition relationships may have been affected by seasonal variation in organic matter availability, we also conducted a controlled year-round mesocosm experiment. Here 4 degrees C warming led to 51% higher total annual CH4 ebullition, while diffusion was not affected. Our combined findings suggest that global warming will strongly enhance freshwater CH4 emissions through a disproportional increase in ebullition (6-20% per 1 degrees C increase), contributing to global warming.

PMID- 29167455 TI - Intelligence is associated with the modular structure of intrinsic brain networks. AB - General intelligence is a psychological construct that captures in a single metric the overall level of behavioural and cognitive performance in an individual. While previous research has attempted to localise intelligence in circumscribed brain regions, more recent work focuses on functional interactions between regions. However, even though brain networks are characterised by substantial modularity, it is unclear whether and how the brain's modular organisation is associated with general intelligence. Modelling subject-specific brain network graphs from functional MRI resting-state data (N = 309), we found that intelligence was not associated with global modularity features (e.g., number or size of modules) or the whole-brain proportions of different node types (e.g., connector hubs or provincial hubs). In contrast, we observed characteristic associations between intelligence and node-specific measures of within- and between-module connectivity, particularly in frontal and parietal brain regions that have previously been linked to intelligence. We propose that the connectivity profile of these regions may shape intelligence-relevant aspects of information processing. Our data demonstrate that not only region-specific differences in brain structure and function, but also the network-topological embedding of fronto-parietal as well as other cortical and subcortical brain regions is related to individual differences in higher cognitive abilities, i.e., intelligence. PMID- 29167456 TI - Warming, shading and a moth outbreak reduce tundra carbon sink strength dramatically by changing plant cover and soil microbial activity. AB - Future increases in temperature and cloud cover will alter plant growth and decomposition of the large carbon pools stored in Arctic soils. A better understanding of interactions between above- and belowground processes and communities of plants and microorganisms is essential for predicting Arctic ecosystem responses to climate change. We measured ecosystem CO2 fluxes during the growing season for seven years in a dwarf-shrub tundra in West Greenland manipulated with warming and shading and experiencing a natural larvae outbreak. Vegetation composition, soil fungal community composition, microbial activity, and nutrient availability were analyzed after six years of treatment. Warming and shading altered the plant community, reduced plant CO2 uptake, and changed fungal community composition. Ecosystem carbon accumulation decreased during the growing season by 61% in shaded plots and 51% in warmed plots. Also, plant recovery was reduced in both manipulations following the larvae outbreak during the fifth treatment year. The reduced plant recovery in manipulated plots following the larvae outbreak suggests that climate change may increase tundra ecosystem sensitivity to disturbances. Also, plant community changes mediated via reduced light and reduced water availability due to increased temperature can strongly lower the carbon sink strength of tundra ecosystems. PMID- 29167457 TI - The genetic basis for the adaptation of E. coli to sugar synthesis from CO2. AB - Understanding the evolution of a new metabolic capability in full mechanistic detail is challenging, as causative mutations may be masked by non-essential "hitchhiking" mutations accumulated during the evolutionary trajectory. We have previously used adaptive laboratory evolution of a rationally engineered ancestor to generate an Escherichia coli strain able to utilize CO2 fixation for sugar synthesis. Here, we reveal the genetic basis underlying this metabolic transition. Five mutations are sufficient to enable robust growth when a non native Calvin-Benson-Bassham cycle provides all the sugar-derived metabolic building blocks. These mutations are found either in enzymes that affect the efflux of intermediates from the autocatalytic CO2 fixation cycle toward biomass (prs, serA, and pgi), or in key regulators of carbon metabolism (crp and ppsR). Using suppressor analysis, we show that a decrease in catalytic capacity is a common feature of all mutations found in enzymes. These findings highlight the enzymatic constraints that are essential to the metabolic stability of autocatalytic cycles and are relevant to future efforts in constructing non native carbon fixation pathways. PMID- 29167458 TI - Assembly of CRISPR ribonucleoproteins with biotinylated oligonucleotides via an RNA aptamer for precise gene editing. AB - Writing specific DNA sequences into the human genome is challenging with non viral gene-editing reagents, since most of the edited sequences contain various imprecise insertions or deletions. We developed a modular RNA aptamer streptavidin strategy, termed S1mplex, to complex CRISPR-Cas9 ribonucleoproteins with a nucleic acid donor template, as well as other biotinylated molecules such as quantum dots. In human cells, tailored S1mplexes increase the ratio of precisely edited to imprecisely edited alleles up to 18-fold higher than standard gene-editing methods, and enrich cell populations containing multiplexed precise edits up to 42-fold. These advances with versatile, preassembled reagents could greatly reduce the time and cost of in vitro or ex vivo gene-editing applications in precision medicine and drug discovery and aid in the development of increased and serial dosing regimens for somatic gene editing in vivo. PMID- 29167459 TI - ZIKV infection regulates inflammasomes pathway for replication in monocytes. AB - ZIKV causes microcephaly by crossing the placental barrier, however, the mechanism of trans-placental dissemination of ZIKV remains unknown. Here, we sought to determine whether monocytes, which can cross tissue barriers, assist ZIKV dissemination to the fetus. We determined this by infecting monocytes with two strains of ZIKV: South American (PRVABC59) and Nigerian (IBH30656) and analyzing viral replication. We found that ZIKV infects and replicates in monocytes and macrophages, which results in the modulation of a large number of cellular genes. Analysis of these genes identified multiple pathways including inflammasome to be targeted by ZIKV, which was confirmed by analyzing the transcript levels of the proteins of inflammasome pathways, NLRP3, ASC, caspase 1, IL-1 and IL-18. Interestingly, IFNalpha and the IFN inducible gene, MxA were not enhanced, suggesting prevention of innate antiviral defense by ZIKV. Also, inhibition of inflammasome led to an increased transcriptional activity of IFNalpha, MxA and CXCL10. Based on these results we suggest that ZIKV transcription is regulated by inflammasomes. PMID- 29167460 TI - Early vaccination protects against childhood leukemia: A systematic review and meta-analysis. AB - Leukemia is the most commonly diagnosed childhood cancer, although its etiology is still largely unknown. Growing evidence supports a role for infection in the etiology of acute lymphocytic leukemia (ALL), and the involvement of the immune system suggests that vaccination may also play a role. However, the findings presented in the published literature are inconsistent. Therefore, we conducted a PRISMA systematic review and meta-analysis. 14 studies were identified and meta analyzed. Vaccinations studied comprised Bacillus Calmette-Guerin (BCG) vaccine, Triple vaccine, Hepatitis B vaccine (HBV), Polio, Measles, Rubella, Mumps, trivalent MMR vaccine and Haemophilus influenza type B (HiB) vaccine. We observed a protective association between any vaccination in the first year of life and risk of childhood leukemia (summary odds ratio (OR) 0.58 [95% confidence interval (CI) 0.36-0.91]). When individual vaccines were analysed, some evidence of an association was seen only for BCG (summary OR 0.73 [95% CI 0.50-1.08]). In conclusion, early vaccination appears to be associated with a reduced risk of childhood leukemia. This finding may be underpinned by the association observed for BCG. Given the relatively imprecise nature of the results of this meta analysis, our findings should be interpreted cautiously and replicated in future studies. PMID- 29167461 TI - New Description of Evolution of Magnetic Phases in Artificial Honeycomb Lattice. AB - Artificial magnetic honeycomb lattice provides a two-dimensional archetypal system to explore novel phenomena of geometrically frustrated magnets. According to theoretical reports, an artificial magnetic honeycomb lattice is expected to exhibit several phase transitions to unique magnetic states as a function of reducing temperature. Experimental investigations of permalloy artificial honeycomb lattice of connected ultra-small elements, [Formula: see text] 12 nm, reveal a more complicated behavior. First, upon cooling the sample to intermediate temperature, [Formula: see text] 175 K, the system manifests a non unique state where the long range order co-exists with short-range magnetic charge order and weak spin ice state. Second, at much lower temperature, [Formula: see text] 6 K, the long-range spin solid state exhibits a re-entrant behavior. Both observations are in direct contrast to the present understanding of this system. New theoretical approaches are needed to develop a comprehensive formulation of this two dimensional magnet. PMID- 29167462 TI - Inactivation of KCNQ1 potassium channels reveals dynamic coupling between voltage sensing and pore opening. AB - In voltage-activated ion channels, voltage sensor (VSD) activation induces pore opening via VSD-pore coupling. Previous studies show that the pore in KCNQ1 channels opens when the VSD activates to both intermediate and fully activated states, resulting in the intermediate open (IO) and activated open (AO) states, respectively. It is also well known that accompanying KCNQ1 channel opening, the ionic current is suppressed by a rapid process called inactivation. Here we show that inactivation of KCNQ1 channels derives from the different mechanisms of the VSD-pore coupling that lead to the IO and AO states, respectively. When the VSD activates from the intermediate state to the activated state, the VSD-pore coupling has less efficacy in opening the pore, producing inactivation. These results indicate that different mechanisms, other than the canonical VSD-pore coupling, are at work in voltage-dependent ion channel activation. PMID- 29167463 TI - Structural insights into the committed step of bacterial phospholipid biosynthesis. AB - The membrane-integral glycerol 3-phosphate (G3P) acyltransferase PlsY catalyses the committed and essential step in bacterial phospholipid biosynthesis by acylation of G3P, forming lysophosphatidic acid. It contains no known acyltransferase motifs, lacks eukaryotic homologs, and uses the unusual acyl phosphate as acyl donor, as opposed to acyl-CoA or acyl-carrier protein for other acyltransferases. Previous studies have identified several PlsY inhibitors as potential antimicrobials. Here we determine the crystal structure of PlsY at 1.48 A resolution, revealing a seven-transmembrane helix fold. Four additional substrate- and product-bound structures uncover the atomic details of its relatively inflexible active site. Structure and mutagenesis suggest a different acylation mechanism of 'substrate-assisted catalysis' that, unlike other acyltransferases, does not require a proteinaceous catalytic base to complete. The structure data and a high-throughput enzymatic assay developed in this work should prove useful for virtual and experimental screening of inhibitors against this vital bacterial enzyme. PMID- 29167464 TI - North Atlantic variability and its links to European climate over the last 3000 years. AB - The subpolar North Atlantic is a key location for the Earth's climate system. In the Labrador Sea, intense winter air-sea heat exchange drives the formation of deep waters and the surface circulation of warm waters around the subpolar gyre. This process therefore has the ability to modulate the oceanic northward heat transport. Recent studies reveal decadal variability in the formation of Labrador Sea Water. Yet, crucially, its longer-term history and links with European climate remain limited. Here we present new decadally resolved marine proxy reconstructions, which suggest weakened Labrador Sea Water formation and gyre strength with similar timing to the centennial cold periods recorded in terrestrial climate archives and historical records over the last 3000 years. These new data support that subpolar North Atlantic circulation changes, likely forced by increased southward flow of Arctic waters, contributed to modulating the climate of Europe with important societal impacts as revealed in European history. PMID- 29167466 TI - Mussel larvae modify calcifying fluid carbonate chemistry to promote calcification. AB - Understanding mollusk calcification sensitivity to ocean acidification (OA) requires a better knowledge of calcification mechanisms. Especially in rapidly calcifying larval stages, mechanisms of shell formation are largely unexplored yet these are the most vulnerable life stages. Here we find rapid generation of crystalline shell material in mussel larvae. We find no evidence for intracellular CaCO3 formation, indicating that mineral formation could be constrained to the calcifying space beneath the shell. Using microelectrodes we show that larvae can increase pH and [CO32-] beneath the growing shell, leading to a ~1.5-fold elevation in calcium carbonate saturation state (Omegaarag). Larvae exposed to OA exhibit a drop in pH, [CO32-] and Omegaarag at the site of calcification, which correlates with decreased shell growth, and, eventually, shell dissolution. Our findings help explain why bivalve larvae can form shells under moderate acidification scenarios and provide a direct link between ocean carbonate chemistry and larval calcification rate. PMID- 29167465 TI - Coupling of Polo kinase activation to nuclear localization by a bifunctional NLS is required during mitotic entry. AB - The Polo kinase is a master regulator of mitosis and cytokinesis conserved from yeasts to humans. Polo is composed of an N-term kinase domain (KD) and a C-term polo-box domain (PBD), which regulates its subcellular localizations. The PBD and KD can interact and inhibit each other, and this reciprocal inhibition is relieved when Polo is phosphorylated at its activation loop. How Polo activation and localization are coupled during mitotic entry is unknown. Here we report that PBD binding to the KD masks a nuclear localization signal (NLS). Activating phosphorylation of the KD leads to exposure of the NLS and entry of Polo into the nucleus before nuclear envelope breakdown. Failures of this mechanism result in misregulation of the Cdk1-activating Cdc25 phosphatase and lead to mitotic and developmental defects in Drosophila. These results uncover spatiotemporal mechanisms linking master regulatory enzymes during mitotic entry. PMID- 29167467 TI - Chinese CO2 emission flows have reversed since the global financial crisis. AB - This study seeks to estimate the carbon implications of recent changes in China's economic development patterns and role in global trade in the post-financial crisis era. We utilised the latest socioeconomic datasets to compile China's 2012 multiregional input-output (MRIO) table. Environmentally extended input-output analysis and structural decomposition analysis (SDA) were applied to investigate the driving forces behind changes in CO2 emissions embodied in China's domestic and foreign trade from 2007 to 2012. Here we show that emission flow patterns have changed greatly in both domestic and foreign trade since the financial crisis. Some economically less developed regions, such as Southwest China, have shifted from being a net emission exporter to being a net emission importer. In terms of foreign trade, emissions embodied in China's exports declined from 2007 to 2012 mainly due to changes in production structure and efficiency gains, while developing countries became the major destination of China's export emissions. PMID- 29167468 TI - Transcriptome and metabolite analyses reveal the complex metabolic genes involved in volatile terpenoid biosynthesis in garden sage (Salvia officinalis). AB - A large number of terpenoid compounds have been extracted from different tissues of S. officinalis. However, the molecular genetic basis of terpene biosynthesis pathways is virtually unknown. In this study, approximately 6.6 Gb of raw data were generated from the transcriptome of S. officinalis leaves using Illumina HiSeq 2000 sequencing. After filtering and removing the adapter sequences from the raw data, the number of reads reached 21 million, comprising 98 million of high-quality nucleotide bases. 48,671 unigenes were assembled de novo and annotated for establishing a valid database for studying terpenoid biosynthesis. We identified 135 unigenes that are putatively involved in terpenoid metabolism, including 70 mevalonate and methyl-erythritol phosphate pathways, terpenoid backbone biosynthesis genes, and 65 terpene synthase genes. Moreover, five terpene synthase genes were studied for their functions in terpenoid biosynthesis by using transgenic tobacco; most transgenic tobacco plants expressing these terpene synthetic genes produced increased amounts of terpenoids compared with wild-type control. The combined data analyses from the transcriptome and metabolome provide new insights into our understanding of the complex metabolic genes in terpenoid-rich sage, and our study paves the way for the future metabolic engineering of the biosynthesis of useful terpene compounds in S. officinalis. PMID- 29167469 TI - Baseline and Breakthrough Resistance Mutations in HCV Patients Failing DAAs. AB - Sustained virologic response rates have increased dramatically following direct acting antiviral (DAA) therapy in chronic HCV infection. However, resistance associated substitutions (RASs) may occur either prior to DAA or following drug exposure. The aim of this study was to determine RASs in DAA treatment-failing patients and the role of RASs in failure treatment. Six hundred and twenty HCV patients were evaluated. Direct sequencing of HCV genes was performed at breakthrough in all 31 patients failing DAAs, and in 19 baseline patients. Deep sequencing analysis was performed in 15/19 baseline patients. RASs were detected at breakthrough in 17/31 patients and at baseline in 11/19 patients, although, only 8/19 patients carried RASs associated with the prescribed regimen. Deep sequencing analysis showed RASs at baseline in 10/15 treatment-failing patients. No significant difference was observed with the Sanger sequencing. Treatment failure in the 14/31 patients without RASs was associated with suboptimal treatment. In 54.8% of treatment-failing patients one of the causes of failure might be the presence of RASs. In the majority of patients with RASs, mutations were present at baseline. Direct resistance test is advocated before treatment and at breakthrough in order to optimize retreatment regimens. PMID- 29167470 TI - Glucagon-like peptide-1 mimetics, optimal for Asian type 2 diabetes patients with and without overweight/obesity: meta-analysis of randomized controlled trials. AB - Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are desirable for diabetes, especially in patients with overweight/obesity. We aimed to determine whether GLP 1RAs exhibit different glucose-lowering efficacies between Asian type 2 diabetes (T2D) patients with and without overweight/obesity. Randomized controlled trials were searched in EMBASE, MEDLINE, CENTRAL, and ClinicalTrials.gov. Studies published in English with treatment duration >=12 weeks and information on HbA1c changes were included. The studies were divided into normal body mass index (BMI) and overweight/obese groups according to baseline BMI. Among 3190 searched studies, 20 trials were included in the meta-analysis. The standardized mean differences in HbA1c change, fasting glucose change, and postprandial glucose change were equivalent between normal BMI and overweight/obese studies (p > 0.05). The relative risk of HbA1c < 6.5% target achievement in normal BMI trials (7.93; 95% confidence interval: 3.27, 19.20) was superior to that in overweight/obesity trials (2.23; 1.67, 2.97), with a significant difference (p = 0.020). Body weight loss (p = 0.572) and hypoglycemic risk(p = 0.920) were similar in the two groups. The glucose-lowering effects of GLP-1RAs were equivalent among Asian T2D patients. With their advantages for weight-loss or weight-maintenance, GLP-1RAs are optimal medicines for Asian T2D patients with and without overweight/obesity. PMID- 29167472 TI - Two opposite size effects of hardness at real nano-scale and their distinct origins. AB - Although it has been well known that hardness of metals obtained with conical indenter remains a constant of about 3 times yield strength in conventional tests, and hardness will show a size effect of increasing hardness with decreasing indentation depth in micro-scale beyond 100 nm, the nano-indentation hardness experiments within 100 nm indentation depth usually show a large deviation and unclear trends. We report the cross-validated experimental and numerical results of two opposite depth-dependences of hardness at real nano scale. That is to say, the indentation size effect (ISE) of hardness of single crystal copper shows a rapid increase and then a slow decrease with increasing indentation depth within 100 nm depth. All of the results were coss-checked by means of both elaborated nano-indentation experiments with calibrated indenter tips and large scale molecular dynamics (MD) simulations. Further analysis of the MD results and experimental data reveal that the two opposite ISE of nano hardness should be attributed to the finite roundness of the indenter tip and the intrinsic transition governing property of the material.

AB - Approximately 30% of locally advanced rectal cancer patients might not benefit from chemoradiotherapy; however, the response to neoadjuvant chemoradiotherapy in these cases is difficult to predict. Pim-3 is a member of the provirus integration site for a moloney murine leukemia virus family of proteins that contributes to cell proliferation, survival, and chemotherapy resistance. Therefore, the relationship between Pim-3 expression and response to neoadjuvant chemoradiotherapy in rectal cancer patients is important to evaluate. 175 rectal cancer patients who underwent neoadjuvant treatment enrolled in this study. The relationship between Pim-3 expression on immunohistochemical analysis of rectal cancer tissue, which was obtained before treatment, the response to chemoradiotherapy and survival was investigated. The patients with no Pim-3 expression were more likely to achieve a pathologic complete response to chemoradiotherapy than patients with Pim-3 expression (P = 0.001). Cox multivariate analysis showed that the significant prognostic factors were Pim-3 expression (P = 0.003) and the number of neoadjuvant chemotherapy cycles (P = 0.005) for overall survival. Neoadjuvant chemotherapy cycles (P = 0.007), adjuvant chemotherapy cycles (P = 0.004) and pathology types (P = 0.049) were significant prognostic factors for disease-free survival. Pim-3 is a potential predictive biomarker for the response of rectal cancer to chemoradiotherapy. PMID- 29167473 TI - Two-Dimensional Co2S2 monolayer with robust ferromagnetism. AB - Design and synthesis of two-dimensional (2D) materials with robust intrinsic ferromagnetism is highly desirable due to their potential applications in spintronics devices. In this work, we identify a new 2D cobalt sulfide (Co2S2) material by using first-principles calculations and particle swarm optimization (PSO) global structure search. We show that the 2D Co2S2 is most stable in the litharge type tetragonal structure with space group of P4/nmm. The elastic constants, phonon spectrum, and molecular dynamics simulation confirm its mechanical, dynamical and thermal stability, respectively. It is also found that Co2S2 monolayer is a ferromagnetic metal with a Curie temperature up to 404 K. In addition, we propose a feasible procedure to synthesize the Co2S2 monolayer by chemically exfoliating from bulk TlCo2S2 phase.

Amorphous MoSx shows better intrinsic activity than crystalline MoS2. And the composition and amorphous structure of MoSx could be expediently tuned by absorbed dose for excellent catalytic activity. Meanwhile, the addition of carbon black leads to a significant decrease of charge transfer resistance and increase of active sites of MoSx/C composite. Consequently, MoSx/C nanocomposite shows Pt-like catalytic activity towards hydrogen evolution reaction (HER), which requires an onset over potential of 40 mV and over potential of 76 mV to achieve a current density of 10 mA cm-2, and the corresponding Tafel slope is 48 mV decade-1. After 6000 CV cycles, the catalytic activity of MoSx/C shows no obvious decrease. However, when platinum (Pt) foil is used as counter electrode, MoSx/C composite show better catalytic activity abnormally after long-term cycling tests. The dissolution of Pt was observed in HER and the Pt dissolution mechanism is elucidated by further analyzing the surface composition of after-cycling electrodes, which offers highly valuable guidelines for using Pt electrode in HER.

AB - Electric field modulation of magnetic properties via magnetoelectric coupling in composite materials is of fundamental and technological importance for realizing tunable energy efficient electronics. Here we provide foundational analysis on magnetoelectric voltage tunable inductor (VTI) that exhibits extremely large inductance tunability of up to 1150% under moderate electric fields. This field dependence of inductance arises from the change of permeability, which correlates with the stress dependence of magnetic anisotropy. Through combination of analytical models that were validated by experimental results, comprehensive understanding of various anisotropies on the tunability of VTI is provided. Results indicate that inclusion of magnetic materials with low magnetocrystalline anisotropy is one of the most effective ways to achieve high VTI tunability. This study opens pathway towards design of tunable circuit components that exhibit field-dependent electronic behavior.

AB - Chronic levodopa treatment leads to the appearance of dyskinesia in the majority of Parkinson's disease patients. Neurovascular dysregulation in putaminal and pallidal regions is thought to be an underlying feature of this complication of treatment. We used microPET to study unilaterally lesioned 6-hydroxydopamine rats that developed levodopa-induced abnormal involuntary movements (AIMs) after three weeks of drug treatment. Animals were scanned with [15O]-labeled water and [18F] fluorodeoxyglucose, to map regional cerebral blood flow and glucose metabolism, and with [11C]-isoaminobutyric acid (AIB), to assess blood-brain-barrier (BBB) permeability, following separate injections of levodopa or saline. Multitracer scan data were acquired in each animal before initiating levodopa treatment, and again following the period of daily drug administration. Significant dissociation of vasomotor and metabolic levodopa responses was seen in the striatum/globus pallidus (GP) of the lesioned hemisphere. These changes were accompanied by nearby increases in [11C]-AIB uptake in the ipsilateral GP, which correlated with AIMs scores. Histopathological analysis revealed high levels of microvascular nestin immunoreactivity in the same region. The findings demonstrate that regional flow-metabolism dissociation and increased BBB permeability are simultaneously induced by levodopa within areas of active microvascular remodeling, and that such changes correlate with the severity of dyskinesia.

AB - Using a set of state-of-the-art quantum chemical techniques we scrutinized the characteristically different reactivity of frustrated and classical Lewis pairs towards molecular hydrogen. The mechanisms and reaction profiles computed for the H2 splitting reaction of various Lewis pairs are in good agreement with the experimentally observed feasibility of H2 activation. More importantly, the analysis of activation parameters unambiguously revealed the existence of two reaction pathways through a low-energy and a high-energy transition state. An exhaustive scrutiny of these transition states, including their stability, geometry and electronic structure, reflects that the electronic rearrangement in low-energy transition states is fundamentally different from that of high-energy transition states. Our findings reveal that the widespread consensus mechanism of H2 splitting characterizes activation processes corresponding to high-energy transition states and, accordingly, is not operative for H2-activating systems. One of the criteria of H2-activation, actually, is the availability of a low energy transition state that represents a different H2 splitting mechanism, in which the electrostatic field generated in the cavity of Lewis pair plays a critical role: to induce a strong polarization of H2 that facilities an efficient end-on acid-H2 interaction and to stabilize the charge separated "H+-H-" moiety in the transition state. PMID- 29167478 TI - An Evolutionary Game Theory Model of Spontaneous Brain Functioning. AB - Our brain is a complex system of interconnected regions spontaneously organized into distinct networks. The integration of information between and within these networks is a continuous process that can be observed even when the brain is at rest, i.e. not engaged in any particular task. Moreover, such spontaneous dynamics show predictive value over individual cognitive profile and constitute a potential marker in neurological and psychiatric conditions, making its understanding of fundamental importance in modern neuroscience. Here we present a theoretical and mathematical model based on an extension of evolutionary game theory on networks (EGN), able to capture brain's interregional dynamics by balancing emulative and non-emulative attitudes among brain regions. This results in the net behavior of nodes composing resting-state networks identified using functional magnetic resonance imaging (fMRI), determining their moment-to-moment level of activation and inhibition as expressed by positive and negative shifts in BOLD fMRI signal. By spontaneously generating low-frequency oscillatory behaviors, the EGN model is able to mimic functional connectivity dynamics, approximate fMRI time series on the basis of initial subset of available data, as well as simulate the impact of network lesions and provide evidence of compensation mechanisms across networks. Results suggest evolutionary game theory on networks as a new potential framework for the understanding of human brain network dynamics.

AB - Time-dependent responses of materials to an ultrashort optical pulse carry valuable information about the electronic and lattice dynamics; this research area has been widely studied on novel two-dimensional materials such as graphene, transition metal dichalcogenides (TMDs) and topological insulators (TIs). We report herein a time-resolved and angle-resolved photoemission spectroscopy (TRARPES) study of WSe2, a layered semiconductor of interest for valley electronics. The results for below-gap optical pumping reveal energy-gain and loss Floquet replica valence bands that appear instantaneously in concert with the pump pulse. Energy shift, broadening, and complex intensity variation and oscillation at twice the phonon frequency for the valence bands are observed at time scales ranging from the femtosecond to the picosecond and beyond. The underlying physics is rich, including ponderomotive interaction, dressing of the electronic states, creation of coherent phonon pairs, and diffusion of charge carriers - effects operating at vastly different time domains. PMID- 29167481 TI - Influence of experimental parameters on the laser heating of an optical trap. AB - In optical tweezers, heating of the sample due to absorption of the laser light is a major concern as temperature plays an important role at microscopic scale. A popular rule of thumb is to consider that, at the typical wavelength of 1064 nm, the focused laser induces a heating rate of B = 1 degrees C/100 mW. We analysed this effect under different routine experimental conditions and found a remarkable variability in the temperature increase. Importantly, we determined that temperature can easily rise by as much as 4 degrees C at a relatively low power of 100 mW, for dielectric, non-absorbing particles with certain sets of specific, but common, parameters. Heating was determined from measurements of light momentum changes under drag forces at different powers, which proved to provide precise and robust results in watery buffers. We contrasted the experiments with computer simulations and obtained good agreement. These results suggest that this remarkable heating could be responsible for changes in the sample under study and could lead to serious damage of live specimens. It is therefore advisable to determine the temperature increase in each specific experiment and avoid the use of a universal rule that could inadvertently lead to critical changes in the sample. PMID- 29167480 TI - Dynamical Binding Modes Determine Agonistic and Antagonistic Ligand Effects in the Prostate-Specific G-Protein Coupled Receptor (PSGR). AB - We analysed the ligand-based activation mechanism of the prostate-specific G protein coupled receptor (PSGR), which is an olfactory receptor that mediates cellular growth in prostate cancer cells. Furthermore, it is an olfactory receptor with a known chemically near identic antagonist/agonist pair, alpha- and beta-ionone. Using a combined theoretical and experimental approach, we propose that this receptor is activated by a ligand-induced rearrangement of a protein internal hydrogen bond network. Surprisingly, this rearrangement is not induced by interaction of the ligand with the network, but by dynamic van der Waals contacts of the ligand with the involved amino acid side chains, altering their conformations and intraprotein connectivity. Ligand recognition in this GPCR is therefore highly stereo selective, but seemingly lacks any ligand recognition via polar contacts. A putative olfactory receptor-based drug design scheme will have to take this unique mode of protein/ligand action into account.

AB - The centipede Scolopendra has important medicinal value and high toxicity, making it to be an interesting subject for evolutionary studies. However, species identification in China is difficult because of limited resource exploration and lack of recent taxonomic revision. To improve the identification and taxonomy of the genus Scolopendra in China, an in-depth investigation was conducted, and an integrated method that combined morphological characteristics with molecular data was applied. The identification key was revised to show the main difference among species. Our results indicated that morphologically-delimited species were consistent with the molecular analysis inferred from the COI sequences with genetic distances and phylogenetic trees. Additional morphometrics of four characteristics provided criteria for shape variation. These results suggested that the members of the genus Scolopendra in China could be delineated as 14 separate species. A new species from Lufeng county, Yunnan province, was proposed according to its characteristics, which was named as S. lufengia sp. nov. Our results comprehensively ascertained the taxonomic status of Scolopendra species in China, explored their phylogenetic relationships, showed a high success in the identification of medicinal centipedes. PMID- 29167483 TI - Encapsulation of primary dopaminergic neurons in a GDNF-loaded collagen hydrogel increases their survival, re-innervation and function after intra-striatal transplantation. AB - Poor graft survival limits the use of primary dopaminergic neurons for neural repair in Parkinson's disease. Injectable hydrogels have the potential to significantly improve the outcome of such reparative approaches by providing a physical matrix for cell encapsulation which can be further enriched with pro survival factors. Therefore, this study sought to determine the survival and efficacy of primary dopaminergic grafts after intra-striatal delivery in a glial derived neurotrophic factor (GDNF)-loaded collagen hydrogel in a rat model of Parkinson's disease. After intra-striatal transplantation into the lesioned striatum, the GDNF-enriched collagen hydrogel significantly improved the survival of dopaminergic neurons in the graft (5-fold), increased their capacity for striatal re-innervation (3-fold), and enhanced their functional efficacy. Additional studies suggested that this was due to the hydrogel's ability to retain GDNF in the microenvironment of the graft, and to protect the transplanted cells from the host immune response. In conclusion, the encapsulation of dopaminergic neurons in a GDNF-loaded hydrogel dramatically increased their survival and function, providing further evidence of the potential of biomaterials for neural transplantation and brain repair in neurodegenerative diseases such as Parkinson's disease. PMID- 29167484 TI - Possible mechanisms of control of Fusarium wilt of cut chrysanthemum by Phanerochaete chrysosporium in continuous cropping fields: A case study. AB - Continuous cropping is a universal challenge in agriculture because it has adverse physiological effects on plants, resulting in stunting, inferior quality, and even massive loss in harvest due to diseases. In this study, Phanerochaete chrysosporium was inoculated into the field in which cut chrysanthemum had already been continuously cropped for five years to control wilt disease. After 120 days of cultivation, the addition of P. chrysosporium significantly improved the physiological status of plants and changed the bacterial and fungal community structure in the soil. The bacterial quantity in the treatment increased by 1.76 times, but the fungal quantity, especially the quantity of Fusarium oxysporum, decreased significantly in comparison with the control. The investigation into the mechanisms of control of Fusarium wilt of cut chrysanthemum by P. chrysosporium showed that P. chrysosporium in soil can inhibit the growth of F. oxysporum and decrease p-hydroxybenzoic acid (HA), which stimulates the propagation of F. oxysporum. Based on current evidence, the inhibition by P. chrysosporium and change in HA appear to be the main causes of the alleviation of wilt disease in the treatment. Other factors, such as nutrients, might also have an influence on the wilt disease of cut chrysanthemum. PMID- 29167485 TI - Sleep Deprivation Diminishes Attentional Control Effectiveness and Impairs Flexible Adaptation to Changing Conditions. AB - Insufficient sleep is a global public health problem resulting in catastrophic accidents, increased mortality, and hundreds of billions of dollars in lost productivity. Yet the effect of sleep deprivation (SD) on decision making and performance is often underestimated by fatigued individuals and is only beginning to be understood by scientists. The deleterious impact of SD is frequently attributed to lapses in vigilant attention, but this account fails to explain many SD-related problems, such as loss of situational awareness and perseveration. Using a laboratory study protocol, we show that SD individuals can maintain information in the focus of attention and anticipate likely correct responses, but their use of such a top-down attentional strategy is less effective at preventing errors caused by competing responses. Moreover, when the task environment requires flexibility, performance under SD suffers dramatically. The impairment in flexible shifting of attentional control we observed is distinct from lapses in vigilant attention, as corroborated by the specificity of the influence of a genetic biomarker, the dopaminergic polymorphism DRD2 C957T. Reduced effectiveness of top-down attentional control under SD, especially when conditions require flexibility, helps to explain maladaptive performance that is not readily explained by lapses in vigilant attention. PMID- 29167486 TI - Distinctive Clinical Effects of Haemorrhagic Markers in Cerebral Amyloid Angiopathy. AB - Restricted lobar cerebral microbleeds (CMBs) and cortical superficial siderosis (CSS) are the characteristic markers of cerebral amyloid angiopathy (CAA). However, their effects on clinical features has not been evaluated well. The purpose of this study is to investigate the clinical implication of these markers in clinical-radiologically diagnosed CAA. A total of 372 patients with possible or probable CAA who met the modified Boston criteria were recruited in a memory clinic setting. Cortical thickness was measured using surface based methods. Presence of restricted multiple lobar CMBs were independently associated with cortical thinning across the entire cortical regions while presence of CSS was independently associated with cortical thinning primarily in the bilateral frontal region. Presence of restricted multiple lobar CMBs was associated with impairment in all cognitive domains such as attention, language, visuospatial, memory and frontal executive functions while presence of CSS was associated with attention and frontal dysfunction. The relationships of restricted multiple lobar CMBs or CSS with cognitive impairment were partially mediated by thinning in the corresponding cortical regions. Our findings suggested that restricted multiple lobar CMBs and CSS affect distinctive clinical features, providing new insights into potential mechanisms in CAA. PMID- 29167487 TI - Comparative metagenomics of hydrocarbon and methane seeps of the Gulf of Mexico. AB - Oil and gas percolate profusely through the sediments of the Gulf of Mexico, leading to numerous seeps at the seafloor, where complex microbial, and sometimes animal communities flourish. Sediments from three areas (two cold seeps with contrasting hydrocarbon composition and a site outside any area of active seepage) of the Gulf of Mexico were investigated and compared. Consistent with the existence of a seep microbiome, a distinct microbial community was observed in seep areas compared to sediment from outside areas of active seepage. The microbial community from sediments without any influence from hydrocarbon seepage was characterized by Planctomycetes and the metabolic potential was consistent with detrital marine snow degradation. By contrast, in seep samples with methane as the principal hydrocarbon, methane oxidation by abundant members of ANME-1 was likely the predominant process. Seep samples characterized by fluids containing both methane and complex hydrocarbons, were characterized by abundant Chloroflexi (Anaerolinaceae) and deltaproteobacterial lineages and exhibited potential for complex hydrocarbon degradation. These different metabolic capacities suggested that microorganisms in cold seeps can potentially rely on other processes beyond methane oxidation and that the hydrocarbon composition of the seep fluids may be a critical factor structuring the seafloor microbial community composition and function. PMID- 29167488 TI - Mott transition in chain structure of strained VO2 films revealed by coherent phonons. AB - The characteristic of strongly correlated materials is the Mott transition between metal and insulator (MIT or IMT) in the same crystalline structure, indicating the presence of a gap formed by the Coulomb interaction between carriers. The physics of the transition needs to be revealed. Using VO2, as a model material, we observe the emergence of a metallic chain in the intermediate insulating monoclinic structure (M2 phase) of epitaxial strained films, proving the Mott transition involving the breakdown of the critical Coulomb interaction. It is revealed by measuring the temperature dynamics of coherent optical phonons with separated vibrational modes originated from two substructures in M2: one is the charge-density-wave, formed by electron-phonon (e-ph) interaction, and the other is the equally spaced insulator-chain with electron-electron (e-e) correlations. PMID- 29167489 TI - T helper cells with specificity for an antigen in cardiomyocytes promote pressure overload-induced progression from hypertrophy to heart failure. AB - We investigated whether CD4+-T cells with specificity for an antigen in cardiomyocytes promote the progression from hypertrophy to heart failure in mice with increased pressure load due to transverse aortic constriction (TAC). OT-II mice expressing a transgenic T cell receptor (TCR) with specificity for ovalbumin (OVA) on CD4+-T cells and cMy-mOVA mice expressing OVA on cardiomyocytes were crossed. The resulting cMy-mOVA-OT-II mice did not display signs of spontaneous autoimmunity despite the fact that their OVA-specific CD4+-T cells were not anergic. After TAC, progression to heart failure was significantly accelerated in cMy-mOVA-OT-II compared to cMy-mOVA mice. No OVA-specific antibodies were induced in response to TAC in cMy-mOVA-OT-II mice, yet more CD3+ T cells infiltrated their myocardium when compared with TAC-operated cMy-mOVA mice. Systemically, the proportion of activated CD4+-T cells with a Th1 and Th17 cytokine profile was increased in cMy-mOVA-OT-II mice after TAC. Thus, T helper cells with specificity for an antigen in cardiomyocytes can directly promote the progression of heart failure in response to pressure overload independently of autoantibodies. PMID- 29167490 TI - Strongly Coupled Magnetic and Electronic Transitions in Multivalent Strontium Cobaltites. AB - The topotactic phase transition in SrCoO x (x = 2.5-3.0) makes it possible to reversibly transit between the two distinct phases, i.e. the brownmillerite SrCoO2.5 that is a room-temperature antiferromagnetic insulator (AFM-I) and the perovskite SrCoO3 that is a ferromagnetic metal (FM-M), owing to their multiple valence states. For the intermediate x values, the two distinct phases are expected to strongly compete with each other. With oxidation of SrCoO2.5, however, it has been conjectured that the magnetic transition is decoupled to the electronic phase transition, i.e., the AFM-to-FM transition occurs before the insulator-to-metal transition (IMT), which is still controversial. Here, we bridge the gap between the two-phase transitions by density-functional theory calculations combined with optical spectroscopy. We confirm that the IMT actually occurs concomitantly with the FM transition near the oxygen content x = 2.75. Strong charge-spin coupling drives the concurrent IMT and AFM-to-FM transition, which fosters the near room-T magnetic transition characteristic. Ultimately, our study demonstrates that SrCoO x is an intriguingly rare candidate for inducing coupled magnetic and electronic transition via fast and reversible redox reactions. PMID- 29167491 TI - Use of cues in virtual reality depends on visual feedback. AB - 3D motion perception is of central importance to daily life. However, when tested in laboratory settings, sensitivity to 3D motion signals is found to be poor, leading to the view that heuristics and prior assumptions are critical for 3D motion perception. Here we explore an alternative: sensitivity to 3D motion signals is context-dependent and must be learned based on explicit visual feedback in novel environments. The need for action-contingent visual feedback is well-established in the developmental literature. For example, young kittens that are passively moved through an environment, but unable to move through it themselves, fail to develop accurate depth perception. We find that these principles also obtain in adult human perception. Observers that do not experience visual consequences of their actions fail to develop accurate 3D motion perception in a virtual reality environment, even after prolonged exposure. By contrast, observers that experience the consequences of their actions improve performance based on available sensory cues to 3D motion. Specifically, we find that observers learn to exploit the small motion parallax cues provided by head jitter. Our findings advance understanding of human 3D motion processing and form a foundation for future study of perception in virtual and natural 3D environments. PMID- 29167492 TI - Radioligand binding analysis of alpha 2 adrenoceptors with [11C]yohimbine in brain in vivo: Extended Inhibition Plot correction for plasma protein binding. AB - We describe a novel method of kinetic analysis of radioligand binding to neuroreceptors in brain in vivo, here applied to noradrenaline receptors in rat brain. The method uses positron emission tomography (PET) of [11C]yohimbine binding in brain to quantify the density and affinity of alpha 2 adrenoceptors under condition of changing radioligand binding to plasma proteins. We obtained dynamic PET recordings from brain of Spraque Dawley rats at baseline, followed by pharmacological challenge with unlabeled yohimbine (0.3 mg/kg). The challenge with unlabeled ligand failed to diminish radioligand accumulation in brain tissue, due to the blocking of radioligand binding to plasma proteins that elevated the free fractions of the radioligand in plasma. We devised a method that graphically resolved the masking of unlabeled ligand binding by the increase of radioligand free fractions in plasma. The Extended Inhibition Plot introduced here yielded an estimate of the volume of distribution of non-displaceable ligand in brain tissue that increased with the increase of the free fraction of the radioligand in plasma. The resulting binding potentials of the radioligand declined by 50-60% in the presence of unlabeled ligand. The kinetic unmasking of inhibited binding reflected in the increase of the reference volume of distribution yielded estimates of receptor saturation consistent with the binding of unlabeled ligand. PMID- 29167494 TI - Picture Interpretation Test (PIT) 360 degrees : An Innovative Measure of Executive Functions. AB - The assessment of executive functions poses researchers with several challenges related to both the complexity of the construct of executive functions itself and/or the methodological difficulties related to its evaluation. The main objective of the current study was to evaluate a 360 degrees version of an ecologically valid assessment called the Picture Interpretation Test (PIT). Participants included 19 patients with Parkinson's disease (PD) and 19 healthy controls. All participants endorsed globally positive experiences of the PIT 360 degrees . Furthermore, findings indicated that patients with PD took longer to correctly interpret the PIT 360 degrees scene and tended to significantly focus on details of the 360 degrees scene instead of the most informative elements. The time needed for a correct interpretation of the presented scene also correlated significantly with performance in conventional paper and pencil tests of executive functions for patients with PD. Classification analysis indicated the potential of the PIT 360 degrees for distinguishing between patients with PD and healthy controls. Overall, these data provide preliminary evidence in support of the PIT 360 degrees for evaluating executive functions. PMID- 29167493 TI - Functional aspects of salivary nitric oxide synthase of Rhodnius prolixus (Hemiptera, Reduviidae) and nitric oxide trafficking at the vector-host interface. AB - Rhodnius prolixus expresses nitric oxide synthase (NOS) in the cytosol of the salivary gland (SG) cells. The NO produced is stored in the SG lumen bound to NO carrier haemeproteins called nitrophorins (NPs). NPs bind tightly to NO in the acidic SG lumen, but release NO when the pH becomes high, e.g., at the host skin (pH~7.4). NO elicits potent and transient relaxation of vascular smooth muscle. Here, we investigated the role of salivary NO in the R. prolixus feeding behaviour and the salivary vasodilator activity of the host microcirculation. NOS knockdown in R. prolixus changed the SG colour, decreased the number of NO-loaded NPs and caused impairment of feeding performance. When salivary gland extracts (SGEs) were obtained from NOS- and NPs-knockdown insects and prepared in pH 5.0 solution and injected (i.v.) into mice via the tail vein, no vasodilation was observed, whereas SGEs from control insects caused long-term venodilation in the mouse skin. SGs disrupted directly in PBS (pH 7.4) containing BSA produced long term vasodilation compared to the controls without BSA due to the possible formation of nitroso-albumin, suggesting that host serum albumin extends the NO half-life when NO is injected into the host skin by triatomine during their blood feeding. PMID- 29167495 TI - Changes in cardiac arrest patients' temperature management after the publication of 2015 AHA guidelines for resuscitation in China. AB - A survey was performed to assess the current management of targeted temperature management (TTM) in patients following cardiac arrest (CA) and whether healthcare providers will change target temperature after publication of 2015 American Heart Association guidelines for resuscitation in China. 52 hospitals were selected from whole of China between August to November 2016. All healthcare providers in EMs and/or ICUs of selected hospitals participated in the study. 1952 respondents fulfilled the survey (86.8%). TTM in CA patients was declared by 14.5% of physicians and 6.7% of the nurses. Only 4 of 64 departments, 7.8% of physicians and 5.7% of the nurses had implemented TH for CA patients. Since the publication of 2015 AHA guidelines, 33.6% of respondents declared no modification of target temperature, whereas 51.5% declared a target temperature's change in future practice. Respondents were more likely to choose 35~36 degrees C-TTM (54.7%) after guidelines publication, as compared to that before guidelines publication they preferred 32~34 degrees C-TTM (54.0%). TTM for CA patients was still in the early stage in China. Publication of 2015 resuscitation guidelines did have impact on choice of target temperature among healthcare providers. They preferred 35~36 degrees C-TTM after guidelines publication. PMID- 29167496 TI - Temporal depolarization of mitochondria during M phase. AB - Mitochondrial activity in cells must be tightly controlled in response to changes in intracellular circumstances. Despite drastic changes in intracellular conditions and mitochondrial morphology, it is not clear how mitochondrial activity is controlled during M phase of the cell cycle. Here, we show that mitochondrial activity is drastically changed during M phase. Mitochondrial membrane potential changed during M phase progression. Mitochondria were polarized until metaphase to the same extent as mitochondria in interphase cells, but were depolarized at around telophase and cytokinesis. After cytokinesis, mitochondrial membrane potential was recovered. In addition, the generation of superoxide anions in mitochondria was significantly reduced at metaphase even in the presence of antimycin A, an inhibitor of complex III. These results suggest that the electron supply to the mitochondrial electron transfer chain is suppressed during M phase. This suppression might decrease the reactive oxygen species generated by the fragmentation of mitochondria during M phase. PMID- 29167498 TI - Micromechanical Resonator Driven by Radiation Pressure Force. AB - Radiation pressure exerted by light on any surface is the pressure generated by the momentum of impinging photons. The associated force - fundamentally, a quantum mechanical aspect of light - is usually too small to be useful, except in large-scale problems in astronomy and astrodynamics. In atomic and molecular optics, radiation pressure can be used to trap or cool atoms and ions. Use of radiation pressure on larger objects such as micromechanical resonators has been so far limited to its coupling to an acoustic mode, sideband cooling, or levitation of microscopic objects. In this Letter, we demonstrate direct actuation of a radio-frequency micromechanical plate-type resonator by the radiation pressure force generated by a standard laser diode at room temperature. Using two independent methods, the magnitude of the resonator's response to forcing by radiation pressure is found to be proportional to the intensity of the incident light. PMID- 29167497 TI - Development and validation of scFv-conjugated affinity silk protein for specific detection of carcinoembryonic antigen. AB - The production costs for monoclonal antibodies (MAbs) utilized in medical diagnostic kits are inevitably high because the MAbs are mostly obtained from hybridoma cell culture. Here, we report the development and validation of a novel affinity silk protein produced by transgenic silkworm technology as a possible alternative diagnostic tool for cancers. We generated a transgenic silkworm expressing a cDNA construct containing fibroin L-chain fused to a single-chain variable fragment (scFv) derived from a MAb against carcinoembryonic antigen (CEA). The transgenic cocoons were dissolved in aqueous lithium bromide solution, applied to 96-well plates, and analysed by enzyme-linked immunosorbent assay. The scFv-conjugated affinity silk protein specifically recognized CEA as well as the parental MAb. The binding activity was retained after several months of storage in coated plates or concentrated solution. Thus, the scFv-conjugated affinity silk protein provides a potentially useful alternative to conventional MAbs in medical diagnostic kits. PMID- 29167499 TI - A Novel Multiplex HRM Assay to Detect Clopidogrel Resistance. AB - Clopidogrel is an antiplatelet medicine used to prevent blood clots in patients who have had a heart attack, stroke, or other symptoms. Variability in the clinical response to clopidogrel treatment has been attributed to genetic factors. In particular, five SNPs of rs4244285, rs4986893, rs12248560, rs662 and rs1045642 have been associated with resistance to clopidogrel therapy in Chinese population. This work involves the development of a multiplex high-resolution melting (HRM) assay to genotype all five of these loci in 2 tubes. Amplicons corresponding to distinct SNPs in a common tube were designed with the aid of uMelt prediction software to have different melting temperatures Tm by addition of a GC-rich tail to the 5' end of the certain primers. Two kinds of commercial methods, Digital Fluorescence Molecular Hybridization (DFMH) and Sanger sequencing, were used as a control. Three hundred sixteen DFMH pretested samples from consecutive acute coronary syndrome patients were used for a blinded study of multiplex HRM. The sensitivity of HRM was 100% and the specificity was 99.93% reflecting detection of variants other than the known resistance SNPs. Multiplex HRM is an effective closed-tube, highly accurate, fast, and inexpensive method for genotyping the 5 clopidogrel resistance associated SNPs. PMID- 29167500 TI - Insights into the species-specific metabolic engineering of glucosinolates in radish (Raphanus sativus L.) based on comparative genomic analysis. AB - Glucosinolates (GSLs) and their hydrolysis products present in Brassicales play important roles in plants against herbivores and pathogens as well as in the protection of human health. To elucidate the molecular mechanisms underlying the formation of species-specific GSLs and their hydrolysed products in Raphanus sativus L., we performed a comparative genomics analysis between R. sativus and Arabidopsis thaliana. In total, 144 GSL metabolism genes were identified, and most of these GSL genes have expanded through whole-genome and tandem duplication in R. sativus. Crucially, the differential expression of FMOGS-OX2 in the root and silique correlates with the differential distribution of major aliphatic GSL components in these organs. Moreover, MYB118 expression specifically in the silique suggests that aliphatic GSL accumulation occurs predominantly in seeds. Furthermore, the absence of the expression of a putative non-functional epithiospecifier (ESP) gene in any tissue and the nitrile-specifier (NSP) gene in roots facilitates the accumulation of distinctive beneficial isothiocyanates in R. sativus. Elucidating the evolution of the GSL metabolic pathway in R. sativus is important for fully understanding GSL metabolic engineering and the precise genetic improvement of GSL components and their catabolites in R. sativus and other Brassicaceae crops. PMID- 29167501 TI - Dengue fatal cases present virus-specific HMGB1 response in peripheral organs. AB - Dengue is an important infectious disease that presents high incidence and yields a relevant number of fatal cases (about 20,000) every year worldwide. Despite its epidemiological relevance, there are many knowledge gaps concerning dengue pathogenesis, especially with regards to the circumstances that drive a mild clinical course to a severe disease. In this work, we investigated the participation of high mobility group box 1 (HMGB1), an important modulator of inflammation, in dengue fatal cases. Histopathological and ultrastructural analyses revealed that liver, lung and heart post-mortem samples were marked by tissue abnormalities, such as necrosis and apoptotic cell death. These observations go in line with an HMGB1-mediated response and raised concerns regarding the participation of this cytokine in promoting/perpetuating inflammation in severe dengue. Further experiments of immunohistochemistry (IHC) showed increased expression of cytoplasmic HMGB1 in dengue-extracted tissues when compared to non-dengue controls. Co-staining of DENV RNA and HMGB1 in the host cell cytoplasm, as found by in situ hybridization and IHC, confirmed the virus specific induction of the HMGB1-mediated response in these peripheral tissues. This report brings the first in-situ evidence of the participation of HMGB1 in severe dengue and highlights novel considerations in the development of dengue immunopathogenesis.

AB - To investigate the effects of maternal fasting plasma glucose (FPG) and pre pregnancy weight status (PPWS) on offspring birth measures and body mass index z score (BMI-z) in the first year, we conducted a prospective study of 1,096 mother infant dyads in Guangdong, China, 2014-2015. Multivariate logistic regression was used to test independent/interaction associations of maternal FPG and PPWS with macrosomia/large for gestational age (LGA). Association of PPWS and FPG with offspring BMI-z in the first year was assessed by the linear mixed effects models. For each 1-mmol/L increase in FPG, the risk of macrosomia and LGA was elevated by 2.74 and 2.01 (95% CI: 1.85, 7.60 and 1.54, 5.88), respectively. No main effect of PPWS or interaction association of FPG and PPWS on macrosomia/LGA was observed (P > 0.05). A relation between maternal FPG and PPWS was detected (P < 0.05). Infants of Q5 FPG mothers, those who were born to OWO mothers, had a 0.35 increase in the BMI-z (95% CI: 0.16, 0.55) compared with infants of NW mothers. In conclusion, maternal FPG is positively associated with macrosomia/LGA. Maternal PPWS and FPG considerably interacted for the association with the risk of offspring high BMI-z in the first year.

AB - Psychrophiles are extremophilic organisms capable of thriving in cold environments. Proteins from these cold-adapted organisms can remain physiologically functional at low temperatures, but are structurally unstable even at moderate temperatures. Here, we report the crystal structure of adenylate kinase (AK) from the Antarctic fish Notothenia coriiceps, and identify the structural basis of cold adaptation by comparison with homologues from tropical fishes including Danio rerio. The structure of N. coriiceps AK (AKNc) revealed suboptimal hydrophobic packing around three Val residues in its central CORE domain, which are replaced with Ile residues in D. rerio AK (AKDr). The Val-to Ile mutations that improve hydrophobic CORE packing in AKNc increased stability at high temperatures but decreased activity at low temperatures, suggesting that the suboptimal hydrophobic CORE packing is important for cold adaptation. Such linkage between stability and activity was also observed in AKDr. Ile-to-Val mutations that destabilized the tropical AK resulted in increased activity at low temperatures. Our results provide the structural basis of cold adaptation of a psychrophilic enzyme from a multicellular, eukaryotic organism, and highlight the similarities and differences in the structural adjustment of vertebrate and bacterial psychrophilic AKs during cold adaptation. PMID- 29167504 TI - Tunable plasmonic substrates with ultrahigh Q-factor resonances. AB - Precisely tailored plasmonic substrates can provide a platform for a variety of enhanced plasmonic applications in sensing and imaging. Despite the significant advances made in plasmonics, most plasmonic devices suffer critically from intrinsic absorption losses at optical frequencies, fatally restricting their efficiency. Here, we describe and engineer plasmonic substrates based on metal insulator-metal (MIM) plasmon resonances with ultra-sharp optical transmission responses. Due to their sharp transmission spectrum, the proposed substrates can be utilized for high quality (Q)-factor multi-functional plasmonic applications. Analytical and numerical methods are exploited to investigate the optical properties of the substrates. The optical response of the substrate can be tuned by adjusting the periodicity of the nanograting patterned on the substrate. Fabricated substrates present Q-factors as high as ~40 and refractive index sensing of the surrounding medium as high as 1245 nm/RIU. Our results indicate that by engineering the substrate geometry, the dielectric thickness and incident angle, the radiation losses can be greatly diminished, thus enabling the design of plasmonic substrates with large Q factor and strong sensitivity to the environment. PMID- 29167505 TI - Dissecting the Re-Os molybdenite geochronometer. AB - Rhenium and osmium isotopes have been used for decades to date the formation of molybdenite (MoS2), a common mineral in ore deposits and the world's main source of molybdenum and rhenium. Understanding the distribution of parent 187Re and radiogenic daughter 187Os isotopes in molybdenite is critical in interpreting isotopic measurements because it can compromise the accurate determination and interpretation of mineralization ages. In order to resolve the controls on the distribution of these elements, chemical and isotope mapping of MoS2 grains from representative porphyry copper-molybdenum deposits were performed using electron microprobe and nano-scale secondary ion mass spectrometry. Our results show a heterogeneous distribution of 185,187Re and 192Os isotopes in MoS2, and that both 187Re and 187Os isotopes are not decoupled as previously thought. We conclude that Re and Os are structurally bound or present as nanoparticles in or next to molybdenite grains, recording a complex formation history and hindering the use of microbeam techniques for Re-Os molybdenite dating. Our study opens new avenues to explore the effects of isotope nuggeting in geochronometers. PMID- 29167506 TI - Creation and Annihilation of Skyrmions in the Frustrated Magnets with Competing Exchange Interactions. AB - In triangular-lattice magnets, the coexistence of third-neighbor antiferromagnetic and nearest-neighbor ferromagnetic exchange interactions can induce rich magnetic phases including noncoplanar skyrmion crystals. Based on Monte Carlo simulation, we studied the dependence of magnetic phase transition on exchange interaction strength. Under the consideration of uniaxial anisotropy and magnetic field both perpendicular to the film plane, a large antiferromagnetic exchange interaction induces a high frustration. When the value of antiferromagnetic exchange interaction is one and a half times larger than the ferromagnetic one, a magnetic phase composed of canting spin stripes, never observed in the chiral magnets, forms. Interestingly, different canting spin stripes along three 120 degree propagation directions may coexist randomly in a magnetic phase, attesting that the canting spin stripes are three-fold degenerate states akin to helices and the multiple state of canting spin stripes is a circular configuration with zero skyrmion charge number. Moreover, skyrmions and antiskyrmions can be observed simultaneously in the configuration at the low temperature nearly close to 0 K, and their configuration and diameter properties are discussed. Finally, the mechanisms of skyrmion creation and annihilation are properly interpreted by comparing exchange and Zeeman energy terms. PMID- 29167508 TI - Coral individuality - confluence of change physical splitting and developmental ability of embryos. AB - Previous studies have suggested that blastomeres from the 2-, 4-, or 8-cell stage of corals have the ability to develop into normal primary polyps. However, it is still not known which developmental stage's blastomere produces which juvenile. In this study, we demonstrated that only the blastomeres with animal hemispheres have the capacity to develop into normal primary polyps. Individuality was evaluated using blastomeres isolated from the corals Acropora digitifera, A. intermedia, Dipsastraea lizardensis, and Favites chinensis. On commencement of embryo cleavage, the animal pole was marked using Neutral red staining, and at the 2-, 4-, and 8-cell stages, embryos were divided into individual blastomeres using glass needles. We found that the survival rate and percentage metamorphosis were higher in the larger-sized blastomeres with animal hemispheres. The vegetal hemisphere alone is incapable of developing into a normal primary polyp; however, a ball-shaped embryo with incomplete mesenteries and no pharynx developed in some cases. These results indicate that the animal hemisphere is needed for corals to develop into normal primary polyps, and that the individuality of corals is possibly determined by a combination of the chance physical splitting of embryos by waves and their innate developmental ability. PMID- 29167507 TI - Characterization of the early molecular changes in the glomeruli of Cd151 -/- mice highlights induction of mindin and MMP-10. AB - In humans and FVB/N mice, loss of functional tetraspanin CD151 is associated with glomerular disease characterised by early onset proteinuria and ultrastructural thickening and splitting of the glomerular basement membrane (GBM). To gain insight into the molecular mechanisms associated with disease development, we characterised the glomerular gene expression profile at an early stage of disease progression in FVB/N Cd151 -/- mice compared to Cd151 +/+ controls. This study identified 72 up-regulated and 183 down-regulated genes in FVB/N Cd151 -/- compared to Cd151 +/+ glomeruli (p < 0.05). Further analysis highlighted induction of the matrix metalloprotease MMP-10 and the extracellular matrix protein mindin (encoded by Spon2) in the diseased FVB/N Cd151 -/- GBM that did not occur in the C57BL/6 diseased-resistant strain. Interestingly, mindin was also detected in urinary samples of FVB/N Cd151 -/- mice, underlining its potential value as a biomarker for glomerular diseases associated with GBM alterations. Gene set enrichment and pathway analysis of the microarray dataset showed enrichment in axon guidance and actin cytoskeleton signalling pathways as well as activation of inflammatory pathways. Given the known function of mindin, its early expression in the diseased GBM could represent a trigger of both further podocyte cytoskeletal changes and inflammation, thereby playing a key role in the mechanisms of disease progression. PMID- 29167509 TI - Cartilage intermediate layer protein 1 (CILP1): A novel mediator of cardiac extracellular matrix remodelling. AB - Heart failure is accompanied by extracellular matrix (ECM) remodelling, often leading to cardiac fibrosis. In the present study we explored the significance of cartilage intermediate layer protein 1 (CILP1) as a novel mediator of cardiac ECM remodelling. Whole genome transcriptional analysis of human cardiac tissue samples revealed a strong association of CILP1 with many structural (e.g. COL1A2 r2 = 0.83) and non-structural (e.g. TGFB3 r2 = 0.75) ECM proteins. Gene enrichment analysis further underscored the involvement of CILP1 in human cardiac ECM remodelling and TGFbeta signalling. Myocardial CILP1 protein levels were significantly elevated in human infarct tissue and in aortic valve stenosis patients. CILP1 mRNA levels markedly increased in mouse heart after myocardial infarction, transverse aortic constriction, and angiotensin II treatment. Cardiac fibroblasts were found to be the primary source of cardiac CILP1 expression. Recombinant CILP1 inhibited TGFbeta-induced alphaSMA gene and protein expression in cardiac fibroblasts. In addition, CILP1 overexpression in HEK293 cells strongly (5-fold p < 0.05) inhibited TGFbeta signalling activity. In conclusion, our study identifies CILP1 as a new cardiac matricellular protein interfering with pro-fibrotic TGFbeta signalling, and as a novel sensitive marker for cardiac fibrosis. PMID- 29167510 TI - Connection adaption for control of networked mobile chaotic agents. AB - In this paper, we propose a strategy for the control of mobile chaotic oscillators by adaptively rewiring connections between nearby agents with local information. In contrast to the dominant adaptive control schemes where coupling strength is adjusted continuously according to the states of the oscillators, our method does not request adaption of coupling strength. As the resulting interaction structure generated by this proposed strategy is strongly related to unidirectional chains, by investigating synchronization property of unidirectional chains, we reveal that there exists a certain coupling range in which the agents could be controlled regardless of the length of the chain. This feature enables the adaptive strategy to control the mobile oscillators regardless of their moving speed. Compared with existing adaptive control strategies for networked mobile agents, our proposed strategy is simpler for implementation where the resulting interaction networks are kept unweighted at all time. PMID- 29167511 TI - Transcription factor NF-kappaB is modulated by symbiotic status in a sea anemone model of cnidarian bleaching. AB - Transcription factor NF-kappaB plays a central role in immunity from fruit flies to humans, and NF-kappaB activity is altered in many human diseases. To investigate a role for NF-kappaB in immunity and disease on a broader evolutionary scale we have characterized NF-kappaB in a sea anemone (Exaiptasia pallida; called Aiptasia herein) model for cnidarian symbiosis and dysbiosis (i.e., "bleaching"). We show that the DNA-binding site specificity of Aiptasia NF kappaB is similar to NF-kappaB proteins from a broad expanse of organisms. Analyses of NF-kappaB and IkappaB kinase proteins from Aiptasia suggest that non canonical NF-kappaB processing is an evolutionarily ancient pathway, which can be reconstituted in human cells. In Aiptasia, NF-kappaB protein levels, DNA-binding activity, and tissue expression increase when loss of the algal symbiont Symbiodinium is induced by heat or chemical treatment. Kinetic analysis of NF kappaB levels following loss of symbiosis show that NF-kappaB levels increase only after Symbiodinium is cleared. Moreover, introduction of Symbiodinium into naive Aiptasia larvae results in a decrease in NF-kappaB expression. Our results suggest that Symbiodinium suppresses NF-kappaB in order to enable establishment of symbiosis in Aiptasia. These results are the first to demonstrate a link between changes in the conserved immune regulatory protein NF-kappaB and cnidarian symbiotic status. PMID- 29167512 TI - Matrix metalloproteinase-9 activity and a downregulated Hedgehog pathway impair blood-brain barrier function in an in vitro model of CNS tuberculosis. AB - Central nervous system tuberculosis (CNS TB) has a high mortality and morbidity associated with severe inflammation. The blood-brain barrier (BBB) protects the brain from inflammation but the mechanisms causing BBB damage in CNS TB are uncharacterized. We demonstrate that Mycobacterium tuberculosis (Mtb) causes breakdown of type IV collagen and decreases tight junction protein (TJP) expression in a co-culture model of the BBB. This increases permeability, surface expression of endothelial adhesion molecules and leukocyte transmigration. TJP breakdown was driven by Mtb-dependent secretion of matrix metalloproteinase (MMP) 9. TJP expression is regulated by Sonic hedgehog (Shh) through transcription factor Gli-1. In our model, the hedgehog pathway was downregulated by Mtb stimulation, but Shh levels in astrocytes were unchanged. However, Scube2, a glycoprotein regulating astrocyte Shh release was decreased, inhibiting Shh delivery to brain endothelial cells. Activation of the hedgehog pathway by addition of a Smoothened agonist or by addition of exogenous Shh, or neutralizing MMP-9 activity, decreased permeability and increased TJP expression in the Mtb stimulated BBB co-cultures. In summary, the BBB is disrupted by downregulation of the Shh pathway and breakdown of TJPs, secondary to increased MMP-9 activity which suggests that these pathways are potential novel targets for host directed therapy in CNS TB. PMID- 29167513 TI - Band gap engineering of In(Ga)N/GaN short period superlattices. AB - Discussion of band gap behavior based on first principles calculations of the electronic band structures for several InN/GaN superlattices (SLs) (free-standing and pseudomorphic) grown along different directions (polar and nonpolar) is presented. Taking into account the dependence on internal strain and lattice geometry mainly two factors influence the dependence of the band gap, E g on the layer thickness: the internal electric field and the hyb wells) is more important. We also consider mIn ridization of well and barrier wave functions. We illustrate their influence on the band gap engineering by calculating the strength of built-in electric field and the oscillator strength. It appears that there are two interesting ranges of layer thicknesses. In one the influence of the electric field on the gaps is dominant (wider wells), whereas in the other the wave function hybridization (narrow wells) is more important. We also consider mIn 0.33 Ga 0.67 N/nGaN SLs, which seem to be easier to fabricate than high In content quantum wells. The calculated band gaps are compared with recent experimental data. It is shown that for In(Ga)N/GaN superlattices it is possible to exceed by far the range of band gap values, which can be realized in ternary InGaN alloys. PMID- 29167514 TI - Common origin of the gelsolin gene variant in 62 Finnish AGel amyloidosis families. AB - Finnish gelsolin amyloidosis (AGel amyloidosis) is an autosomal dominantly inherited systemic disorder with ophthalmologic, neurologic and dermatologic symptoms. Only the gelsolin (GSN) c.640G>A variant has been found in the Finnish patients thus far. The purpose of this study was to examine whether the Finnish patients have a common ancestor or whether multiple mutation events have occurred at c.640G, which is a known mutational hot spot. A total of 79 Finnish AGel amyloidosis families including 707 patients were first discovered by means of patient interviews, genealogic studies and civil and parish registers. From each family 1-2 index patients were chosen. Blood samples were available from 71 index patients representing 64 families. After quality control, SNP array genotype data were available from 68 patients from 62 nuclear families. All the index patients had the same c.640G>A variant (rs121909715). Genotyping was performed using the Illumina CoreExome SNP array. The homozygosity haplotype method was used to analyse shared haplotypes. Haplotype analysis identified a shared haplotype, common to all studied patients. This shared haplotype included 17 markers and was 361 kb in length (GRCh37 coordinates 9:124003326-124364349) and this level of haplotype sharing was found to occur highly unlikely by chance. This GSN haplotype ranked as the largest shared haplotype in the 68 patients in a genome wide analysis of haplotype block lengths. These results provide strong evidence that although there is a known mutational hot spot at GSN c.640G, all of the studied 62 Finnish AGel amyloidosis families are genetically linked to a common ancestor. PMID- 29167515 TI - Symmetry breaking, Josephson oscillation and self-trapping in a self-bound three dimensional quantum ball. AB - We study spontaneous symmetry breaking (SSB), Josephson oscillation, and self trapping in a stable, mobile, three-dimensional matter-wave spherical quantum ball self-bound by attractive two-body and repulsive three-body interactions. The SSB is realized by a parity-symmetric (a) one-dimensional (1D) double-well potential or (b) a 1D Gaussian potential, both along the z axis and no potential along the x and y axes. In the presence of each of these potentials, the symmetric ground state dynamically evolves into a doubly-degenerate SSB ground state. If the SSB ground state in the double well, predominantly located in the first well (z > 0), is given a small displacement, the quantum ball oscillates with a self-trapping in the first well. For a medium displacement one encounters an asymmetric Josephson oscillation. The asymmetric oscillation is a consequence of SSB. The study is performed by a variational and a numerical solution of a non linear mean-field model with 1D parity-symmetric perturbations. PMID- 29167516 TI - Nanoparticle core stability and surface functionalization drive the mTOR signaling pathway in hepatocellular cell lines. AB - Specifically designed and functionalized nanoparticles hold great promise for biomedical applications. Yet, the applicability of nanoparticles is critically predetermined by their surface functionalization and biodegradability. Here we demonstrate that amino-functionalized polystyrene nanoparticles (PS-NH2), but not amino- or hydroxyl-functionalized silica particles, trigger cell death in hepatocellular carcinoma Huh7 cells. Importantly, biodegradability of nanoparticles plays a crucial role in regulation of essential cellular processes. Thus, biodegradable silica nanoparticles having the same shape, size and surface functionalization showed opposite cellular effects in comparison with similar polystyrene nanoparticles. At the molecular level, PS-NH2 obstruct and amino functionalized silica nanoparticles (Si-NH2) activate the mTOR signalling in Huh7 and HepG2 cells. PS-NH2 induced time-dependent lysosomal destabilization associated with damage of the mitochondrial membrane. Solely in PS-NH2-treated cells, permeabilization of lysosomes preceded cell death. Contrary, Si-NH2 nanoparticles enhanced proliferation of HuH7 and HepG2 cells. Our findings demonstrate complex cellular responses to functionalized nanoparticles and suggest that nanoparticles can be used to control activation of mTOR signaling with subsequent influence on proliferation and viability of HuH7 cells. The data provide fundamental knowledge which could help in developing safe and efficient nano-therapeutics. PMID- 29167517 TI - The spatiotemporal system dynamics of acquired resistance in an engineered microecology. AB - Great strides have been made in the understanding of complex networks; however, our understanding of natural microecologies is limited. Modelling of complex natural ecological systems has allowed for new findings, but these models typically ignore the constant evolution of species. Due to the complexity of natural systems, unanticipated interactions may lead to erroneous conclusions concerning the role of specific molecular components. To address this, we use a synthetic system to understand the spatiotemporal dynamics of growth and to study acquired resistance in vivo. Our system differs from earlier synthetic systems in that it focuses on the evolution of a microecology from a killer-prey relationship to coexistence using two different non-motile Escherichia coli strains. Using empirical data, we developed the first ecological model emphasising the concept of the constant evolution of species, where the survival of the prey species is dependent on location (distance from the killer) or the evolution of resistance. Our simple model, when expanded to complex microecological association studies under varied spatial and nutrient backgrounds may help to understand the complex relationships between multiple species in intricate natural ecological networks. This type of microecological study has become increasingly important, especially with the emergence of antibiotic resistant pathogens.

PMID- 29167518 TI - Encoding of menstrual pain experience with theta oscillations in women with primary dysmenorrhea. AB - Theta oscillation (4-7 Hz) is well documented for its association with neural processes of memory. Pronounced increase of theta activity is commonly observed in patients with chronic neurogenic pain. However, its association with encoding of pain experience in patients with chronic pain is still unclear. The goal of the present study is to investigate the theta encoding of sensory and emotional information of long-term menstrual pain in women with primary dysmenorrhea (PDM). Forty-six young women with PDM and 46 age-matched control subjects underwent resting-state magnetoencephalography study during menstrual and periovulatory phases. Our results revealed increased theta activity in brain regions of pain processing in women with PDM, including the right parahippocampal gyrus, right posterior insula, and left anterior/middle cingulate gyrus during the menstrual phase and the left anterior insula and the left middle/inferior temporal gyrus during the periovulatory phase. The correlations between theta activity and the psychological measures pertaining to pain experience (depression, state anxiety, and pain rating index) implicate the role of theta oscillations in emotional and sensory processing of pain. The present study provides evidence for the role of theta oscillations in encoding the immediate and sustained effects of pain experience in young women with PDM. PMID- 29167520 TI - High corrosion resistance and weak corrosion anisotropy of an as-rolled Mg-3Al 1Zn (in wt.%) alloy with strong crystallographic texture. AB - Combining with electrochemical corrosion measurements, immersion and hydrogen evolution testing performed in 0.9 wt.% NaCl solution at 37 degrees C, the corrosion resistance of an as-rolled Mg-3%Al-1%Zn alloy before and after a 3% compressive strain along the rolling direction was investigated. Results revealed that the corrosion behavior of differently oriented surfaces of the as-rolled samples with a strong basal texture was obviously different. Among them, the corrosion rate of sample surface with the orientation parallel to the normal direction (ND) of the plate was the fastest, the corrosion rate of sample surface with the orientation parallel to the rolling direction (RD) of the plate took the second place and the corrosion rate of sample surface with the orientation parallel to the transverse direction (TD) was the slowest. After being pre strained, the activation of a high density of {10-12} twins could remarkably reduce the corrosion rate of surrounding alpha-Mg matrix and simultaneously weaken the corrosion anisotropy between differently oriented samples. The main reason was that similar to grain boundaries, twin boundaries acted as physical barriers to the corrosion attack. Moreover, the activated twins increased the protectiveness of surface films and then suppressed the micro corrosion couples occurred in twinned grains. PMID- 29167521 TI - DNA methylation in silkworm genome may provide insights into epigenetic regulation of response to Bombyx mori cypovirus infection. AB - DNA methylation is an important epigenetic modification that regulates a wide range of biological processes including immune response. However, information on the epigenetics-mediated immune mechanisms in insects is limited. Therefore, in this study, we examined transcriptomes and DNA methylomes in the fat body and midgut tissues of silkworm, Bombyx mori with or without B. mori cytoplasmic polyhedrosis virus (BmCPV) infection. The transcriptional profile and the genomic DNA methylation patterns in the midgut and fat body were tissue-specific and dynamically altered after BmCPV challenge. KEGG pathway analysis revealed that differentially methylated genes (DMGs) could be involved in pathways of RNA transport, RNA degradation, nucleotide excision repair, DNA replication, etc. 27 genes were shown to have both differential expression and differential methylation in the midgut and fat body of infected larvae, respectively, indicating that the BmCPV infection-induced expression changes of these genes could be mediated by variations in DNA methylation. BS-PCR validated the hypomethylation of G2/M phase-specific E3 ubiquitin-protein ligase-like gene in the BmCPV infected midgut. These results demonstrated that epigenetic regulation may play roles in host-virus interaction in silkworm and would be potential value for further studies on mechanism of BmCPV epithelial-specific infection and epigenetic regulation in the silkworm. PMID- 29167522 TI - Isolation and functional identification of three cuticle protein genes during metamorphosis of the beet armyworm, Spodoptera exigua. AB - The beet armyworm, Spodoptera exigua (Hubner), is one of the major crop pests and is a target for current pest control approaches using insecticides. In this study three cuticular protein genes CPG316, CPG860 and CPG4855 have been cloned from 0 h pupal integument of S. exigua through race PCR Strategy. The deduced amino acid sequences were found to contain the RR-2 consensus region of other insect cuticular proteins and construct phylogenetic trees for each protein. Using quantitative RT-PCR, the developmental expression of the three genes through several larval and the early pupal stages was studied. All three genes contribute to the endocuticle although CPG316 may have a different role from the other two genes. All three newly isolated genes were analyzed and their functions were determined by using direct injection of the dsRNA into early 5th instar larvae. All genes are expressed in the larvae and early pupae but in different patterns. Furthermore, phenotypic results show that these genes have differing effects on the development of cuticle, its flexibility and a big role in metamorphosis in both larval and pupal stages.

AB - We report the effective synthesis of biocompatible upconversion nanoparticles (UCNP)-loaded phosphate micelles and successful delivery of UCNPs to prostate cancer cells via secreted phospholipase A2 (sPLA-2) enzyme cleavage of the loaded micelles for the first time. The activity of the (sPLA-2) enzyme toward the synthesized micelles was investigated and confirmed by LC-MS. TEM results showed that the micelles have a size distribution of 80 to 150 nm, whereas UCNP-loaded micelles range from 200 to 350 nm, indicating the successful loading of UCNPs. The selective release of UCNPs to prostate cancer cells rather than other cells, specifically cervical cancer cells, was observed and confirmed by a range of bioimaging studies. Moreover, cytotoxicity assays confirmed the biocompatibility of the UCNP-loaded micelles. PMID- 29167527 TI - The effects of diets enriched in omega-3 polyunsaturated fatty acids on systemic vaccinia virus infection. AB - Omega-3 polyunsaturated fatty acids (PUFA, n-3 fatty acids), the key components of fish and flaxseed oils, are increasingly consumed by the public because of their potential health benefits and are available by prescription for hypertriglyceridemia. However, numerous studies have shown that these compounds are immunoregulatory and immunosuppressive and thus may increase susceptibility to infection. In this study, we tested the effects of the amount of fat and the types of fatty acid in the diet on infection by vaccinia virus, an acute infection that begins in the respiratory tract and spreads by viremia to internal organs. Male C57Bl6 mice (~5 week old) were fed for 3 weeks prior to infection and continuing during infection and recovery one of the following: 1) a normal low fat (13% kcal) diet, 2) a low fat diet containing n-3 PUFAs, 3) a high fat (41% kcal) diet rich in n-3 PUFAs, 4) a high fat n-6 PUFA diet, or 5) a high fat monounsaturated diet. We found no statistically significant differences in the susceptibility of mice to viral infection, morbidity, viral organ titers, recovery time, or mortality with these diets, indicating that, over this approximately 6-week time period, dietary fats did not substantially affect responses to poxviral infection. PMID- 29167525 TI - Lineage divergence of activity-driven transcription and evolution of cognitive ability. AB - Excitation-transcription coupling shapes network formation during brain development and controls neuronal survival, synaptic function and cognitive skills in the adult. New studies have uncovered differences in the transcriptional responses to synaptic activity between humans and mice. These differences are caused both by the emergence of lineage-specific activity regulated genes and by the acquisition of signal-responsive DNA elements in gene regulatory regions that determine whether a gene can be transcriptionally induced by synaptic activity or alter the extent of its inducibility. Such evolutionary divergence may have contributed to lineage-related advancements in cognitive abilities. PMID- 29167528 TI - Mercury evasion from a boreal peatland shortens the timeline for recovery from legacy pollution. AB - Peatlands are a major source of methylmercury that contaminates downstream aquatic food webs. The large store of mercury (Hg) in peatlands could be a source of Hg for over a century even if deposition is dramatically reduced. However, the reliability of Hg mass balances can be questioned due to missing long-term land atmosphere flux measurements. We used a novel micrometeorological system for continuous measurement of Hg peatland-atmosphere exchange to derive the first annual Hg budget for a peatland. The evasion of Hg (9.4 ug m-2 yr-1) over the course of a year was seven times greater than stream Hg export, and over two times greater than wet bulk deposition to the boreal peatland. Measurements of dissolved gaseous Hg in the peat pore water also indicate Hg evasion. The net efflux may result from recent declines in atmospheric Hg concentrations that have turned the peatland from a net sink into a source of atmospheric Hg. This net Hg loss suggests that open boreal peatlands and downstream ecosystems can recover more rapidly from past atmospheric Hg deposition than previously assumed. This has important implications for future levels of methylmercury in boreal freshwater fish and the estimation of historical Hg accumulation rates from peat profiles. PMID- 29167529 TI - Liver-specific deletion of RORalpha aggravates diet-induced nonalcoholic steatohepatitis by inducing mitochondrial dysfunction. AB - Mitochondrial dysfunction may play a key role in the progression of steatosis to nonalcoholic steatohepatitis (NASH); however, the molecular mechanism that controls the structure and function of mitochondria in NASH is not clearly understood. Here, we demonstrated that RORalpha is a regulator of expression of Bnip3 and PGC-1alpha, and thereby enhances mitochondrial quality. First, we observed that liver-specific RORalpha knockout mice (RORalpha-LKO) were more susceptible to high-fat diet-induced NASH compared with control, probably due to mitochondrial dysfunction. Concordantly, mitochondrial fission in response to nutrient stimuli was abolished with downregulation of Bnip3 and phospho-Drp1 in the hepatocytes of RORalpha-LKO. RORalpha enhanced oxygen consumption rate and expression of genes associated with mitochondrial quality control. Finally, we observed the positive correlation of the expression levels of Bnip3 and PGC 1alpha with those of RORalpha in patients with steatohepatitis. Together, we demonstrated that RORalpha mediates mitochondrial quality under nutrient overloaded conditions and propose RORalpha as a potential therapeutic target in treatment of NASH. PMID- 29167530 TI - High-density native-range species affects the invasive plant Chromolaena odorata more strongly than species from its invasive range. AB - Invasive plant species often form dense mono-dominant stands in areas they have invaded, while having only sparse distribution in their native ranges, and the reasons behind this phenomenon are a key point of research in invasive species biology. Differences in species composition between native and invasive ranges may contribute to the difference in distribution status. In this study, we found that the high-density condition had a more negative effect on C. odorata than the low-density condition when co-grown with neighbor plants from its native range in Mexico, while this pattern was not in evidence when it was grown with neighbors from its invasive range in China. Different competitive ability and coevolutionary history with C. odorata between native-range neighbors and invasive-range neighbors may lead to the inconsistent patterns.

PMID- 29167532 TI - Long-Read Sequencing of Human Cytomegalovirus Transcriptome Reveals RNA Isoforms Carrying Distinct Coding Potentials. AB - The human cytomegalovirus (HCMV) is a ubiquitous, human pathogenic herpesvirus. The complete viral genome is transcriptionally active during infection; however, a large part of its transcriptome has yet to be annotated. In this work, we applied the amplified isoform sequencing technique from Pacific Biosciences to characterize the lytic transcriptome of HCMV strain Towne varS. We developed a pipeline for transcript annotation using long-read sequencing data. We identified 248 transcriptional start sites, 116 transcriptional termination sites and 80 splicing events. Using this information, we have annotated 291 previously undescribed or only partially annotated transcript isoforms, including eight novel antisense transcripts and their isoforms, as well as a novel transcript (RS2) in the short repeat region, partially antisense to RS1. Similarly to other organisms, we discovered a high transcriptional diversity in HCMV, with many transcripts only slightly differing from one another. Comparing our transcriptome profiling results to an earlier ribosome footprint analysis, we have concluded that the majority of the transcripts contain multiple translationally active ORFs, and also that most isoforms contain unique combinations of ORFs. Based on these results, we propose that one important function of this transcriptional diversity may be to provide a regulatory mechanism at the level of translation.

AB - Becker muscular dystrophy (BMD) is a neuromuscular disorder allelic to Duchenne muscular dystrophy (DMD), caused by in-frame mutations in the dystrophin gene, and characterized by a clinical progression that is both milder and more heterogeneous than DMD. Muscle magnetic resonance imaging (MRI) has been proposed as biomarker of disease progression in dystrophinopathies. Correlation with clinically meaningful outcome measures such as North Star Ambulatory Assessment (NSAA) and 6 minute walk test (6MWT) is paramount for biomarker qualification. In this study, 51 molecularly confirmed BMD patients (aged 7-69 years) underwent muscle MRI and were evaluated with functional measures (NSAA and 6MWT) at the time of the MRI, and subsequently after one year. We confirmed a pattern of fatty substitution involving mainly the hip extensors and most thigh muscles. Severity of muscle fatty substitution was significantly correlated with specific DMD mutations: in particular, patients with an isolated deletion of exon 48, or deletions bordering exon 51, showed milder involvement. Fat infiltration scores correlated with baseline functional measures, and predicted changes after 1 year. We conclude that in BMD, skeletal muscle MRI not only strongly correlates with motor function, but also helps in predicting functional deterioration within a 12 month time frame.

AB - Desert dust over the Indian region during pre-monsoon season is known to strengthen monsoon circulation, by modulating rainfall through the elevated heat pump (EHP) mechanism. In this context, an insight into long term trends of dust loading over this region is of significant importance in understanding monsoon variability. In this study, using long term (2000 to 2015) aerosol measurements from multiple satellites, ground stations and model based reanalysis, we show that dust loading in the atmosphere has decreased by 10 to 20% during the pre monsoon season with respect to start of this century. Our analysis reveals that this decrease is a result of increasing pre-monsoon rainfall that in turn increases (decreases) wet scavenging (dust emissions) and slowing circulation pattern over the Northwestern part of the sub-continent. PMID- 29167536 TI - Energy expenditure estimation from respiration variables. AB - The aim of this study was to develop and cross-validate two models to estimate total energy expenditure (TEE) based on respiration variables in healthy subjects during daily physical activities. Ninety-nine male and female subjects systematically varying in age (18-60 years) and body mass index (BMI; 17-36 kg*m 2) completed eleven aerobic activities with a portable spirometer as the criterion measure. Two models were developed using linear regression analyses with the data from 67 randomly selected subjects (50.0% female, 39.9 +/- 11.8 years, 25.1 +/- 5.2 kg*m-2). The models were cross-validated with the other 32 subjects (49% female, 40.4 +/- 10.7 years, 24.7 +/- 4.6 kg*m-2) by applying equivalence testing and Bland-and-Altman analyses. Model 1, estimating TEE based solely on respiratory volume, respiratory rate, and age, was significantly equivalent to the measured TEE with a systematic bias of 0.06 kJ*min-1 (0.22%) and limits of agreement of +/-6.83 kJ*min-1. Model 1 was as accurate in estimating TEE as Model 2, which incorporated further information on activity categories, heart rate, sex, and BMI. The results demonstrated that respiration variables and age can be used to accurately determine daily TEE for different types of aerobic activities in healthy adults across a broad range of ages and body sizes.

AB - Tobacco brown spot, caused by Alternaria species, is a devastating tobacco disease. To explore the role of a group III histidine kinase (AlHK1) on A. longipes pathogenesis, the invasion progress of A. longipes was monitored. We found that the wild-type strain C-00 invaded faster than the AlHK1-disrupted strain HK?4 in the early and middle infection stages and the reverse trend occurred in the late infection stage. Then, eight invasion transcriptomes were performed using RNA-Seq and 205 shared, 505 C-00 and 222 HK?4 specific differentially expressed genes (DEGs) were identified. The annotation results showed seven antioxidant activity genes were specifically identified in the HKDelta4 DEGs. A subsequent experiment confirmed that HKDelta4 was more resistant to low concentrations oxidative stress than C-00. In addition, the results from 1) statistics for the number of DEGs, GO enriched terms, DEGs in clusters with rising trends, and 2) analyses of the expression patterns of some DEGs relevant for osmoadaptation and virulence showed that changes in C-00 infection existed mainly in the early and middle stages, while HKDelta4 infection arose mainly in the late stage. Our results reveal firstly the pathogenesis of A. longipes regulated by AlHK1 and provide useful insights into the fungal-plant interactions.

PMID- 29167538 TI - A Deep-Dream Virtual Reality Platform for Studying Altered Perceptual Phenomenology. AB - Altered states of consciousness, such as psychotic or pharmacologically-induced hallucinations, provide a unique opportunity to examine the mechanisms underlying conscious perception. However, the phenomenological properties of these states are difficult to isolate experimentally from other, more general physiological and cognitive effects of psychoactive substances or psychopathological conditions. Thus, simulating phenomenological aspects of altered states in the absence of these other more general effects provides an important experimental tool for consciousness science and psychiatry. Here we describe such a tool, which we call the Hallucination Machine. It comprises a novel combination of two powerful technologies: deep convolutional neural networks (DCNNs) and panoramic videos of natural scenes, viewed immersively through a head-mounted display (panoramic VR). By doing this, we are able to simulate visual hallucinatory experiences in a biologically plausible and ecologically valid way. Two experiments illustrate potential applications of the Hallucination Machine. First, we show that the system induces visual phenomenology qualitatively similar to classical psychedelics. In a second experiment, we find that simulated hallucinations do not evoke the temporal distortion commonly associated with altered states. Overall, the Hallucination Machine offers a valuable new technique for simulating altered phenomenology without directly altering the underlying neurophysiology. PMID- 29167539 TI - Genome-wide analysis shows that RNase G plays a global role in the stability of mRNAs in Stenotrophomonas maltophilia. AB - Gene expression is determined by critical processes such as RNA synthesis and degradation. Ribonucleases participate in the coordinated and differential decay of messenger RNAs. We describe a suitable method of normalization and calculation of mRNAs half-life values quantified by RNA-Seq. We determined the mRNA half lives of more than 2000 genes in Stenotrophomonas maltophilia D457 and in an isogenic RNase G deficient mutant. Median half-lives were 2,74 and 3 min in the wild-type and the rng-deficient strain, respectively. The absence of RNase G resulted in an overall enhancement of mRNA half-life times, showing that many RNAs are targets of RNase G in S. maltophilia. Around 40 genes are likely to be regulated directly by RNase G since their half-lives were more than two-fold higher in the rng-deficient mutant. Gene length, GC content or expression levels did not correlate with mRNAs lifetimes, although groups of genes with different functions showed different RNA half-lives. Further, we predicted 1542 gene pairs to be part of the same operons in S. maltophilia. In contrast to what was described for other bacteria, our data indicate that RNase G has a global role in mRNA stability and consequently in the regulation of S. maltophilia gene expression. PMID- 29167540 TI - Water and Blood Repellent Flexible Tubes. AB - A top-down scalable method to produce flexible water and blood repellent tubes is introduced. The method is based on replication of overhanging nanostructures from an aluminum tube template to polydimethylsiloxane (PDMS) via atomic layer deposition (ALD) assisted sacrificial etching. The nanostructured PDMS/titania tubes are superhydrophobic with water contact angles 163 +/- 1 degrees (advancing) and 157 +/- 1 degrees (receding) without any further coating. Droplets are able to slide through a 4 mm (inner diameter) tube with low sliding angles of less than 10 degrees for a 35 uL droplet. The superhydrophobic tube shows up to 5,000 times increase in acceleration of a sliding droplet compared to a control tube depending on the inclination angle. Compared to a free falling droplet, the superhydrophobic tube reduced the acceleration by only 38.55%, as compared to a 99.99% reduction for a control tube. The superhydrophobic tubes are blood repellent. Blood droplets (35 uL) roll through the tubes at 15 degrees sliding angles without leaving a bloodstain. The tube surface is resistant to adhesion of activated platelets unlike planar control titania and smooth PDMS surfaces. PMID- 29167541 TI - Effect of post-cessation hyperglycemia on cardiovascular disease and mortality among middle-aged men: an eight-year longitudinal study. AB - Smoking cessation reduces the risk of cardiovascular disease (CVD), but also elevates fasting serum glucose (FSG) levels. The effect of post-cessation hyperglycemia on cardiovascular disease is unknown. The study population consisted of 127,066 men without type 2 diabetes from the Korean National Health Insurance System - Health Screening Cohort database. Change in smoking habits and FSG was determined by the difference in smoking status and FSG levels from the first (2002 and 2003) and second (2004 and 2005) health examinations. Continual smokers, quitters, ex-smokers, and never smokers were stratified according to FSG elevation. The study participants were followed-up for CVD and CVD-related death from 2006 to 2013. Compared to continual smokers, quitters had decreased risk of CVD among those without FSG elevation (hazard ratio, HR, 0.76, 95% confidence interval, CI, 0.66-0.86) and with FSG elevation (HR 0.83, 95% CI 0.72-0.96). Similarly, quitters had a tendency towards reduced risk of CVD-related death among those without FSG elevation (HR 0.74, 95% CI 0.51-1.09) and with FSG elevation (HR 0.68, 95% CI 0.46-1.03). Post-cessation hyperglycemia did not attenuate the beneficiary risk-reducing effects of quitting on CVD and CVD related death. PMID- 29167543 TI - The role of reproductive isolation in allopolyploid speciation patterns: empirical insights from the progenitors of common wheat. AB - The ability to cause reproductive isolation often varies among individuals within a plant species. We addressed whether such polymorphism influenced speciation of the allopolyploid common wheat (Triticum aestivum L., AABBDD genome) by evaluating the expression of pre-pollination (outcrossing potential) and post pollination (crossability) barriers in Aegilops tauschii Coss. (the D genome progenitor). In total, 201 Ae. tauschii accessions representing the entire natural habitat range of the species were used for anther length measurement and artificial crosses with a Triticum turgidum L. (the AB genome progenitor) tester. Intraspecific comparisons showed that both barriers were more strongly expressed in the TauL1 lineage than in the TauL2 lineage. The ability of Ae. tauschii to cause reproductive isolation in the hybridisation with T. turgidum might have markedly influenced common wheat's speciation by inducing lineage-associated patterns of gene flow. The TauL2 accessions with high potential for natural hybridisation with T. turgidum clustered in the southern coastal Caspian region. This provided phenotypic support for the derivation of the D genome of common wheat from southern Caspian populations. The present study underscored the importance of approaches that incorporate the genealogical and geographic structure of the parental species' reproductive isolation in understanding the mechanism of plant allopolyploid speciation.

PMID- 29167542 TI - Telomerase activity is required for the telomere G-overhang structure in Trypanosoma brucei. AB - Trypanosoma brucei causes fatal human African trypanosomiasis and evades the host immune response by regularly switching its major surface antigen, VSG, which is expressed exclusively from subtelomeric loci. Telomere length and telomere proteins play important roles in regulating VSG silencing and switching. T. brucei telomerase plays a key role in maintaining telomere length, and T. brucei telomeres terminate in a single-stranded 3' G-rich overhang. Understanding the detailed structure of the telomere G-overhang and its maintenance will contribute greatly to better understanding telomere maintenance mechanisms. Using an optimized adaptor ligation assay, we found that most T. brucei telomere G overhangs end in 5' TTAGGG 3', while a small portion of G-overhangs end in 5' TAGGGT 3'. Additionally, the protein and the RNA components of the telomerase (TbTERT and TbTR) and TbKu are required for telomere G-overhangs that end in 5' TTAGGG 3' but do not significantly affect the 5' TAGGGT 3'-ending overhangs, indicating that telomerase-mediated telomere synthesis is important for the telomere G-overhang structure. Furthermore, using telomere oligo ligation mediated PCR, we showed for the first time that the T. brucei telomere 5' end sequence - an important feature of the telomere terminal structure - is not random but preferentially 5' CCTAAC 3'.

AB - Auxin is a key plant regulatory molecule, which acts upon a plethora of cellular processes, including those related to cell differentiation and elongation. Despite the stunning progress in all disciplines of auxin research, the mechanisms of auxin-mediated rapid promotion of cell expansion and underlying rearrangement of cell wall components are poorly understood. This is partly due to the limitations of current methodologies for probing auxin. Here we describe a click chemistry-based approach, using an azido derivative of indole-3-propionic acid. This compound is as an active auxin analogue, which can be tagged in situ. Using this new tool, we demonstrate the existence of putative auxin binding sites in the cell walls of expanding/elongating cells. These binding sites are of protein nature but are distinct from those provided by the extensively studied AUXIN BINDING PROTEIN 1 (ABP1). Using immunohistochemistry, we have shown the apoplastic presence of endogenous auxin epitopes recognised by an anti-IAA antibody. Our results are intriguingly in line with previous observations suggesting some transcription-independent (non-genomic) activity of auxin in cell elongation.

AB - Highly (001)-textured, photoactive WSe2 thin films have been prepared by an amorphous solid-liquid-crystalline solid process promoted by palladium. By increasing the thickness of the Pd promoter film (>=10 nm) the structure and texture of the WSe2 films can be improved significantly. However, these as crystallized WSe2 films are only weakly photoactive in a 0.5 M H2SO4 electrolyte under AM 1.5 solar irradiation which we attribute to an inefficient photogenerated charge transfer across the WSe2/electrolyte interface via the prevailing van der Waals planes of the WSe2 crystallites. In this work photochemically deposited platinum on the p-type WSe2 photocathode is used for an efficient electron transfer thus inducing the hydrogen evolution reaction. Upon illuminating the WSe2 photocathodes in a Pt-ion containing electrolyte, the photogenerated electrons reduce Pt+ to Pt leading to the precipitation of Pt islands, preferentially at edge steps of the WSe2, i.e. at the grain boundaries of the WSe2 crystallites. The increasing amount of Pt islands at the grain boundaries linearly enhances the photocurrent density up to 2.5 mA cm-2 at 0 VRHE in sulfuric acid, the highest reported value up to now for WSe2 thin films. PMID- 29167550 TI - Speeding up bioproduction of selenium nanoparticles by using Vibrio natriegens as microbial factory. AB - Selenium and selenium nanoparticles (SeNPs) are extensively used in biomedicine, electronics and some other industrial applications. The bioproduction of SeNPs is gaining interest as a green method to manufacture these biotechnologically relevant products. Several microorganisms have been used for the production of SeNPs either under aerobic or anaerobic conditions. Vibrio natriegens is a non pathogenic fast-growing bacterium, easily cultured in different carbon sources and that has recently been engineered for easy genetic manipulation in the laboratory. Here we report that V. natriegens was able to perfectly grow aerobically in the presence of selenite concentrations up to 15 mM with a significant survival still observed at concentrations as high as 100 mM selenite. Electron microscopy and X-ray spectroscopy analyses demonstrate that V. natriegens cells growing aerobically in selenite-containing LB medium at 30 degrees C produced spherical electron-dense SeNPs whose size ranged from 100-400 nm. Selenite reduction just started at the beginning of the exponential growth phase and the release of SeNPs was observed after cell lysis. Remarkably, V. natriegens produced SeNPs faster than other described microorganisms that were proposed as model bioreactors for SeNPs production. Thus, the fast-growing V. natriegens bacterium becomes a suitable biocatalyst for bioremediation of selenite and for speeding-up the eco-friendly synthesis of SeNPs. PMID- 29167551 TI - A novel SNP in promoter region of RP11-3N2.1 is associated with reduced risk of colorectal cancer. AB - Single-nucleotide polymorphisms (SNPs) in the promoter region of long intergenic non-coding RNAs (lincRNAs) could play a regulatory role in its expression level and then get involved in colorectal cancer (CRC). Thus, we conducted a two-stage case-control study to investigate the associations of Tag SNPs within the promoter region of selected lincRNAs from microarray data with risk of CRC. A total of 320 cases and 319 controls were recruited in the test set to explore the associations between 16 SNPs with no deviations from Hardy-Weinberg equilibrium (HWE) and risk of CRC. Furthermore, 501 cases and 538 controls were included as the validation set to confirm the significant associations. RP11-3N2.1 rs13230517 polymorphism was found to be negatively associated with CRC in both test set (AA vs. GG, OR = 0.68, 95% CI = 0.48-0.96) and validation set (AA vs. GG, OR = 0.76, 95% CI = 0.59-0.98). Pooled analysis showed that individuals with GA/AA genotypes had a significantly decreased risk of CRC when compared with those carrying GG genotype (OR = 0.74, 95% CI = 0.60-0.90) in the combined set. The crossover analysis revealed that rs13230517 GA/AA carriers had a decreased risk of CRC than GG carriers among non-drinkers in both test and combined set. However, no gene environment multiplicative interactions were found on risk of CRC. Our findings suggest that rs13230517 polymorphism might participate in the pathogenesis of CRC and have the potential to be a biomarker for predicting the risk of CRC. PMID- 29167552 TI - Association of ETS1 polymorphism with granulomatosis with polyangiitis and proteinase 3-anti-neutrophil cytoplasmic antibody positive vasculitis in a Japanese population. AB - ETS proto-oncogene 1, transcription factor (ETS1) is involved in various immune responses. Genome-wide association studies on systemic lupus erythematosus in Chinese populations identified the association of ETS1 polymorphism in 3' untranslated region, rs1128334A, which was associated with lower ETS1 expression. In view of substantial sharing of susceptibility genes across multiple autoimmune diseases, we examined whether ETS1 is associated with a rare autoimmune rheumatic disease, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Association of rs1128334 was tested in 466 Japanese patients with AAV and 1099 healthy controls by logistic regression analysis under the additive model. AAV patients were classified into 285 microscopic polyangiitis (MPA), 92 granulomatosis with polyangiitis (GPA), 56 eosinophilic GPA, and 33 unclassifiable AAV, according to the European Medicines Agency (EMEA) algorithm. Among the patients, 376 were positive for MPO-ANCA and 62 for PR3-ANCA. When the patients were classified according to the EMEA classification, rs1128334A allele was significantly increased in GPA (P = 0.0060, P c = 0.030, odds ratio (OR), 1.54; 95% confidence interval (CI), 1.13-2.10). With respect to the ANCA specificity, significant association was observed in PR3-ANCA positive AAV (P = 0.0042, P c = 0.021, OR, 1.72; 95% CI, 1.19-2.49). In conclusion, ETS1 polymorphism was suggested to be associated with GPA and PR3-ANCA positive AAV in a Japanese population. PMID- 29167553 TI - Updated summary of genome editing technology in human cultured cells linked to human genetics studies. AB - Current deep-sequencing technology provides a mass of nucleotide variations associated with human genetic disorders to accelerate the identification of causative mutations. To understand the etiology of genetic disorders, reverse genetics in human cultured cells is a useful approach for modeling a disease in vitro. However, gene targeting in human cultured cells is difficult because of their low activity of homologous recombination. Engineered endonucleases enable enhancement of the local activation of DNA repair pathways at the human genome target site to rewrite the desired sequence, thereby efficiently generating disease-modeling cultured cell clones. These edited cells can be used to explore the molecular functions of a causative gene product to uncover the etiological mechanisms. The correction of mutations in patient cells using genome editing technology could contribute to the development of unique gene therapies. This technology can also be applied to screening causative mutations. Rare genetic disorders and non-exonic mutation-caused diseases remain frontier in the field of human genetics as it is difficult to validate whether the extracted nucleotide variants are mutation or polymorphism. When isogenic human cultured cells with a candidate variant reproduce the pathogenic phenotypes, it is confirmed that the variant is a causative mutation. PMID- 29167554 TI - Phenotypic expression of a novel desmin gene mutation: hypertrophic cardiomyopathy followed by systemic myopathy. AB - Hypertrophic cardiomyopathy is a heterogeneous disease caused by gene mutations. Most of the disease-causing mutations were found in the genes for sarcomeric proteins, but there are several cases carrying mutations in genes for extra sarcomeric cytoskeletons. Desmin is a member of extra-sarcomeric cytoskeletons and plays an important role in muscle contraction. Mutations in the desmin gene cause various type of general myopathy and/or cardiomyopathy, known as desmin related myopathies. We identified a novel desmin missense mutation, Thr219Pro, in the homozygous state in a patient, who first manifested with hypertrophic cardiomyopathy and later progressed to general myopathy. His parents were heterozygous for the mutation, but showed no clinical abnormality, suggesting the recessive inheritance of the mutation. We here report a severe phenotype of hypertrophic cardiomyopathy preceded the onset of general myopathy caused by a novel homozygous missense mutation in the 1B alpha-helix domain of desmin. PMID- 29167555 TI - Efficacy and safety of low dose alteplase for intravenous thrombolysis in Asian stroke patients: a meta-analysis. AB - Whether low dose alteplase is comparable to standard dose in efficacy and safety for intravenous thrombolysis (IVT) in Asian stroke patients remains unverified. PubMed, EMBASE, and Cochrane Library Database from the beginning to June 30, 2017 were searched. IVT efficacy was measured by favorable outcome (modified Rankin Scale scores of 0-1) at 3 months, and safety measured by mortality within 3 months and symptomatic intracerebral hemorrhage (SICH). Pooled estimates were conducted using fixed- or random-effects model depending on heterogeneity. For SICH, studies were pooled separately according to different definitions. Twelve studies involving 7,905 participants were included. No association was found between alteplase dose and favorable outcome (OR = 0.94, 95% CI 0.78-1.14, P = 0.5; heterogeneity: P hetero = 0.01, I2 = 57.3%) and mortality (OR = 0.87, 95% CI 0.74-1.02, P = 0.08; P hetero = 0.83, I2 = 0) using random- and fixed-effects models, respectively. Low dose alteplase was associated with lower SICH as defined by the National Institute of Neurological Disorders and Stroke study (OR = 0.79, 95% CI 0.64-0.99, P = 0.04; P hetero = 0.57, I2 = 0) using fixed-effects model. Subgroup and sensitivity analysis could change the results significantly. Current limited evidence was insufficient to support the speculation that low dose alteplase was comparable to standard dose in thrombolytic efficacy and safety in Asian stroke patients. PMID- 29167556 TI - Alterations in gut microbiota associated with a cafeteria diet and the physiological consequences in the host. AB - OBJECTIVE: Gut microbiota have been described as key factors in the pathophysiology of obesity and different components of metabolic syndrome (MetS). The cafeteria diet (CAF)-fed rat is a preclinical model that reproduces most of the alterations found in human MetS by simulating a palatable human unbalanced diet. Our objective was to assess the effects of CAF on gut microbiota and their associations with different components of MetS in Wistar rats. METHODS: Animals were fed a standard diet or CAF for 12 weeks. A partial least square-based methodology was used to reveal associations between gut microbiota, characterized by 16S ribosomal DNA gene sequencing, and biochemical, nutritional and physiological parameters. RESULTS: CAF feeding resulted in obesity, dyslipidemia, insulin resistance and hepatic steatosis. These changes were accompanied by a significant decrease in gut bacterial diversity, decreased Firmicutes and an increase in Actinobacteria and Proteobacteria abundances, which were concomitant with increased endotoxemia. Associations of different genera with the intake of lipids and carbohydrates were opposed from those associated with the intake of fiber. Changes in gut microbiota were also associated with the different physiological effects of CAF, mainly increased adiposity and altered levels of plasma leptin and glycerol, consistent with altered adipose tissue metabolism. Also hepatic lipid accretion was associated with changes in microbiota, highlighting the relevance of gut microbiota homeostasis in the adipose-liver axis. CONCLUSIONS: Overall, our results suggest that CAF feeding has a profound impact on the gut microbiome and, in turn, that these changes may be associated with important features of MetS. PMID- 29167557 TI - Factors affecting GEBV accuracy with single-step Bayesian models. AB - A single-step approach to obtain genomic prediction was first proposed in 2009. Many studies have investigated the components of GEBV accuracy in genomic selection. However, it is still unclear how the population structure and the relationships between training and validation populations influence GEBV accuracy in terms of single-step analysis. Here, we explored the components of GEBV accuracy in single-step Bayesian analysis with a simulation study. Three scenarios with various numbers of QTL (5, 50, and 500) were simulated. Three models were implemented to analyze the simulated data: single-step genomic best linear unbiased prediction (GBLUP; SSGBLUP), single-step BayesA (SS-BayesA), and single-step BayesB (SS-BayesB). According to our results, GEBV accuracy was influenced by the relationships between the training and validation populations more significantly for ungenotyped animals than for genotyped animals. SS BayesA/BayesB showed an obvious advantage over SSGBLUP with the scenarios of 5 and 50 QTL. SS-BayesB model obtained the lowest accuracy with the 500 QTL in the simulation. SS-BayesA model was the most efficient and robust considering all QTL scenarios. Generally, both the relationships between training and validation populations and LD between markers and QTL contributed to GEBV accuracy in the single-step analysis, and the advantages of single-step Bayesian models were more apparent when the trait is controlled by fewer QTL. PMID- 29167558 TI - Recurring Amplification at 11q22.1-q22.2 Locus Plays an Important Role in Lymph Node Metastasis and Radioresistance in OSCC. AB - A key feature in the pathogenesis of OSCC is genetic instability, which results in altered expression of genes located in amplified/deleted chromosomal regions. In a previous study we have shown that the amplification of the 11q22.1-q22.2 region, encoding cIAP1 and cIAP2, is associated with lymph node metastasis and poor clinical outcome in OSCC. Here, we validate the aCGH results by nuc ish and detect a weak amplification at the 11q22.1-q22.2 locus in 37% of the 182 samples tested. We find positive correlation of 11q22.1-q22.2 amplification with lymph node metastasis, reduced survival, and increased cancer recurrence, and we observe that patients with 11q22.1-q22.2 amplification fail to respond to radiotherapy. We confirm the concurrent overexpression of cIAP1 and cIAP2 and observe differential subcellular localization of the two proteins in OSCC. To ascertain the roles of cIAP1/cIAP2 in lymph node metastasis and radioresistance, we use an in vitro pre-clinical model and confirm the role of cIAP1 in invasion and the role of cIAP2 in invasion and migration. Studies of other tumor types in which cIAP1 is overexpressed suggest that multi-regimen treatments including SMAC mimetics may be effective. Thus, the evaluation of 11q22.1-q22.2 amplifications in OSCC patients may help choose the most effective treatment.

Analysis on cluster electronic structures shows that the competition between localized and delocalized electronic states governs the stability and magnetic properties of Au19M clusters. PMID- 29167560 TI - Transcriptome responses of Streptococcus mutans to peroxide stress: identification of novel antioxidant pathways regulated by Spx. AB - The oxidative stress regulator Spx is ubiquitously found among Gram-positive bacteria. Previously, we reported identification of two Spx proteins in Streptococcus mutans - SpxA1 was the primary activator of oxidative stress genes whereas SpxA2 served a backup role. Here, we used RNA sequencing to uncover the scope of the H2O2 (peroxide)-stress regulon and to further explore the significance of Spx regulation in S. mutans. The transcriptome data confirmed the relationship between Spx and genes typically associated with oxidative stress, but also identified novel genes and metabolic pathways controlled by Spx during peroxide stress. While individual inactivation of newly identified peroxide stress genes had modest or no obvious consequences to bacterial survival, a phenotype enhancement screen using the ?spxA1 strain as background for creation of double mutants revealed that four of the five genes inactivated were required for stress survival. Physiological and biochemical assays validated, at least in part, the transcriptome data indicating that SpxA1 coordinates transcriptional changes during peroxide stress that modify global metabolism and facilitate production of antioxidants. Collectively, our findings unraveled the scope of the peroxide stress regulon and expand the repertoire of oxidative stress genes in S. mutans, shedding new light on the role of Spx regulation.

AB - Fluorescence nanoscopy imaging permits the observation of periodic supramolecular protein structures in their natural environment, as well as the unveiling of previously unknown protein periodic structures. Deciphering the biological functions of such protein nanostructures requires systematic and quantitative analysis of large number of images under different experimental conditions and specific stimuli. Here we present a method and an open source software for the automated quantification of protein periodic structures in super-resolved images. Its performance is demonstrated by analyzing the abundance and regularity of the spectrin membrane-associated periodic skeleton (MPS) in hippocampal neurons of 2 to 40 days in vitro, imaged by STED and STORM nanoscopy. The automated analysis reveals that both the abundance and the regularity of the MPS increase over time and reach maximum plateau values after 14 DIV. A detailed analysis of the distributions of correlation coefficients provides indication of dynamical assembly and disassembly of the MPS. PMID- 29167562 TI - The directed evolution of ligand specificity in a GPCR and the unequal contributions of efficacy and affinity. AB - G protein-coupled receptors (GPCRs) must discriminate between hundreds of related signal molecules. In order to better understand how GPCR specificity can arise from a common promiscuous ancestor, we used laboratory evolution to invert the specificity of the Saccharomyces cerevisiae mating receptor Ste2. This GPCR normally responds weakly to the pheromone of the related species Kluyveromyces lactis, though we previously showed that mutation N216S is sufficient to make this receptor promiscuous. Here, we found that three additional substitutions, A265T, Y266F and P290Q, can act together to confer a novel specificity for K. lactis pheromone. Unlike wild-type Ste2, this new variant does not rely on differences in binding affinity to discriminate against its non-preferred ligand. Instead, the mutation P290Q is critical for suppressing the efficacy of the native pheromone. These two alternative methods of ligand discrimination were mapped to specific amino acid positions on the peptide pheromones. Our work demonstrates that changes in ligand efficacy can drive changes in GPCR specificity, thus obviating the need for extensive binding pocket re-modeling. PMID- 29167563 TI - Specification of murine ground state pluripotent stem cells to regional neuronal populations. AB - Pluripotent stem cells (PSCs) are a valuable tool for interrogating development, disease modelling, drug discovery and transplantation. Despite the burgeoned capability to fate restrict human PSCs to specific neural lineages, comparative protocols for mouse PSCs have not similarly advanced. Mouse protocols fail to recapitulate neural development, consequently yielding highly heterogeneous populations, yet mouse PSCs remain a valuable scientific tool as differentiation is rapid, cost effective and an extensive repertoire of transgenic lines provides an invaluable resource for understanding biology. Here we developed protocols for neural fate restriction of mouse PSCs, using knowledge of embryonic development and recent progress with human equivalents. These methodologies rely upon naive ground-state PSCs temporarily transitioning through LIF-responsive stage prior to neural induction and rapid exposure to regional morphogens. Neural subtypes generated included those of the dorsal forebrain, ventral forebrain, ventral midbrain and hindbrain. This rapid specification, without feeder layers or embryoid-body formation, resulted in high proportions of correctly specified progenitors and neurons with robust reproducibility. These generated neural progenitors/neurons will provide a valuable resource to further understand development, as well disorders affecting specific neuronal subpopulations. PMID- 29167564 TI - Whole Transcriptome Sequencing Analyses Reveal Molecular Markers of Blood Pressure Response to Thiazide Diuretics. AB - Thiazide diuretics (TD) are commonly prescribed anti-hypertensives worldwide. However, <40% of patients treated with thiazide monotherapy achieve BP control. This study uses whole transcriptome sequencing to identify novel molecular markers associated with BP response to TD. We assessed global RNA expression levels in whole blood samples from 150 participants, representing patients in the upper and lower quartile of BP response to TD from the Pharmacogenomic Evaluation of Antihypertensive Responses (PEAR) (50 whites) and from PEAR-2 (50 whites and 50 blacks). In each study cohort, we performed poly-A RNA-sequencing in baseline samples from 25 responders and 25 non-responders to hydrochlorothiazide (HCTZ) or chlorthalidone. At FDR adjusted p-value < 0.05, 29 genes were differentially expressed in relation to HCTZ or chlorthalidone BP response in whites. For each differentially expressed gene, replication was attempted in the alternate white group and PEAR-2 blacks. CEBPD (meta-analysis p = 1.8 * 10-11) and TSC22D3 (p = 1.9 * 10-9) were differentially expressed in all 3 cohorts, and explain, in aggregate, 21.9% of response variability to TD. This is the first report of the use of transcriptome-wide sequencing data to identify molecular markers of antihypertensive drug response. These findings support CEBPD and TSC22D3 as potential biomarkers of BP response to TD. PMID- 29167565 TI - Increased inflammation, oxidative stress and mitochondrial respiration in brown adipose tissue from obese mice. AB - Obesity is associated with severe metabolic diseases such as type 2 diabetes, insulin resistance, cardiovascular disease and some forms of cancer. The pathophysiology of obesity-induced metabolic diseases has been strongly related to white adipose tissue (WAT) dysfunction through several mechanisms such as fibrosis, apoptosis, inflammation, ER and oxidative stress. However, little is known of whether these processes are also present in brown adipose tissue (BAT) during obesity, and the potential consequences on mitochondrial activity. Here we characterized the BAT of obese and hyperglycemic mice treated with a high-fat diet (HFD) for 20 weeks. The hypertrophic BAT from obese mice showed no signs of fibrosis nor apoptosis, but higher levels of inflammation, ER stress, ROS generation and antioxidant enzyme activity than the lean counterparts. The response was attenuated compared with obesity-induced WAT derangements, which suggests that BAT is more resistant to the obesity-induced insult. In fact, mitochondrial respiration in BAT from obese mice was enhanced, with a 2-fold increase in basal oxygen consumption, through the upregulation of complex III of the electron transport chain and UCP1. Altogether, our results show that obesity is accompanied by an increase in BAT mitochondrial activity, inflammation and oxidative damage. PMID- 29167566 TI - Destructive influence of interlayer coupling on Heider balance in bilayer networks. AB - We consider the problem of Heider balance in a link multiplex, i.e. a special multiplex where coupling exists only between corresponding links. Numerical simulations and analytical calculations demonstrate that the presence of such interlayer connections hinders the emergence of the Heider balance. The effect is especially pronounced when the interactions between layers are negative, similarly as in antiferromagnetically coupled spin layers. The larger is the network, the narrower is the region of coupling parameters where the Heider balance can exist. If the interlayer couplings are of opposite signs and are strong enough, then the link dynamics can be reduced to the system of weakly coupled harmonic oscillators. For large strongly-coupled networks and randomly chosen initial conditions the probability of attaining the Heider balance decreases with the network size N as [Formula: see text]. Our finding can explain a lack of the Heider balance in many social systems, where multilayer structures mediate social interactions. PMID- 29167567 TI - Real-time in vivo imaging reveals localised Nrf2 stress responses associated with direct and metabolism-dependent drug toxicity. AB - The transcription factor Nrf2 coordinates an adaptive response to chemical and oxidative stress characterised by the upregulated expression of cytoprotective target genes. In order to understand the mechanistic relevance of Nrf2 as a marker of drug-induced stress it is important to know if this adaptive response is truly localised in the context of organ-specific drug toxicity. Here, we address this knowledge gap through real-time bioluminescence imaging of transgenic Nrf2-luciferase (Nrf2-luc) reporter mice following administration of the metabolism-dependent hepatotoxin acetaminophen (APAP) or the direct nephrotoxin cisplatin. We detected localised bioluminescence in the liver (APAP) and kidneys (cisplatin) in vivo and ex vivo, whilst qPCR, Taqman low-density array and immunoblot analysis of these tissues further revealed increases in the expression level of several endogenous Nrf2-regulated genes/proteins, including heme oxygenase 1 (Hmox1). Consistent with the toxic effects of APAP in the liver and cisplatin in the kidney, immunohistochemical analysis revealed the elevated expression of luciferase and Hmox1 in centrilobular hepatocytes and in tubular epithelial cells, respectively. In keeping with the role of reactive metabolite formation in APAP-induced chemical stress, both the hepatotoxicity and localised Nrf2-luc response were ameliorated by the cytochrome P450 inhibitor aminobenzotriazole. Together, these findings show that Nrf2 can reflect highly localised cellular perturbations associated with relevant toxicological mechanisms. PMID- 29167568 TI - Elite long jumpers with below the knee prostheses approach the board slower, but take-off more effectively than non-amputee athletes. AB - The use of technological aids to improve sport performance ('techno doping') and inclusion of Paralympic athletes in Olympic events are matters of ongoing debate. Recently, a long jumper with a below the knee amputation (BKA) achieved jump distances similar to world-class athletes without amputations, using a carbon fibre running-specific prosthesis (RSP). We show that athletes with BKA utilize a different, more effective take-off technique in the long jump, which provided the best athlete with BKA a performance advantage of at least 0.13 m compared to non amputee athletes. A maximum speed constraint imposed by the use of RSPs would indicate a performance disadvantage for the long jump. We found slower maximum sprinting speeds in athletes with BKA, but did not find a difference in the overall vertical force from both legs of athletes with BKA compared to non amputees. Slower speeds might originate from intrinsically lower sprinting abilities of athletes with BKA or from more complex adaptions in sprinting mechanics due to the biomechanical and morphological differences induced by RSPs. Our results suggest that due to different movement strategies, athletes with and without BKA should likely compete in separate categories for the long jump. PMID- 29167570 TI - Different protein-protein interface patterns predicted by different machine learning methods. AB - Different types of protein-protein interactions make different protein-protein interface patterns. Different machine learning methods are suitable to deal with different types of data. Then, is it the same situation that different interface patterns are preferred for prediction by different machine learning methods? Here, four different machine learning methods were employed to predict protein protein interface residue pairs on different interface patterns. The performances of the methods for different types of proteins are different, which suggest that different machine learning methods tend to predict different protein-protein interface patterns. We made use of ANOVA and variable selection to prove our result. Our proposed methods taking advantages of different single methods also got a good prediction result compared to single methods. In addition to the prediction of protein-protein interactions, this idea can be extended to other research areas such as protein structure prediction and design. PMID- 29167569 TI - Single-cell analysis reveals the continuum of human lympho-myeloid progenitor cells. AB - The hierarchy of human hemopoietic progenitor cells that produce lymphoid and granulocytic-monocytic (myeloid) lineages is unclear. Multiple progenitor populations produce lymphoid and myeloid cells, but they remain incompletely characterized. Here we demonstrated that lympho-myeloid progenitor populations in cord blood - lymphoid-primed multi-potential progenitors (LMPPs), granulocyte macrophage progenitors (GMPs) and multi-lymphoid progenitors (MLPs) - were functionally and transcriptionally distinct and heterogeneous at the clonal level, with progenitors of many different functional potentials present. Although most progenitors had the potential to develop into only one mature cell type ('uni-lineage potential'), bi- and rarer multi-lineage progenitors were present among LMPPs, GMPs and MLPs. Those findings, coupled with single-cell expression analyses, suggest that a continuum of progenitors execute lymphoid and myeloid differentiation, rather than only uni-lineage progenitors' being present downstream of stem cells. PMID- 29167571 TI - A windable and stretchable three-dimensional all-inorganic membrane for efficient oil/water separation. AB - There is strong interest in windable and stretchable membranes to meet the technological demands of practical water treatments. Oil/water separating membranes of this type is still significantly underdeveloped. Here, we reported a windable and stretchable membrane with three-dimensional structure for efficient oil/water separation. This membrane is made of ZnO nanorods arrays conformally grown on woven carbon microfibers. This three-dimensional architecture endows the fabricated membrane with highly windable and stretchable properties, at the same time ensures ZnO nanorods fully exposed outwards on the membrane surface. Due to its superior hydrophilicity and oleophobicity of ZnO nanorods, this all-inorganic membrane exhibits outstanding antifouling property, with the foulants on membrane surfaces easily removed by simple physical cleaning without chemicals. The membrane can effectively separate both oil/saline-water mixtures and oil-in-water emulsions, solely driven by gravity, with extremely high permeation flux of 20933.4 L m-2 h-1 and high separation efficiency over 99%. PMID- 29167572 TI - Anti-Psl Targeting of Pseudomonas aeruginosa Biofilms for Neutrophil-Mediated Disruption. AB - Bacterial biofilms are recalcitrant to antibiotic therapy and a major cause of persistent and recurrent infections. New antibody-based therapies may offer potential to target biofilm specific components for host-cell mediated bacterial clearance. For Pseudomonas aeruginosa, human monoclonal antibodies (mAbs) targeting the Psl biofilm exopolysaccharide exhibit protective activity against planktonic bacteria in acute infection models. However, anti-Psl mAb activity against P. aeruginosa biofilms is unknown. Here, we demonstrate that anti-Psl mAbs targeting three distinct Psl epitopes exhibit stratified binding in mature in vitro biofilms and bind Psl within the context of a chronic biofilm infection. These mAbs also exhibit differential abilities to inhibit early biofilm events and reduce biomass from mature biofilms in the presence of neutrophils. Importantly, a mAb mixture with neutrophils exhibited the greatest biomass reduction, which was further enhanced when combined with meropenem, a common anti Pseudomonal carbapenem antibiotic. Moreover, neutrophil-mediated killing of biofilm bacteria correlated with the evident mAb epitope stratification within the biofilm. Overall, our results suggest that anti-Psl mAbs might be promising candidates for adjunctive use with antibiotics to inhibit/disrupt P. aeruginosa biofilms as a result of chronic infection. PMID- 29167573 TI - Metformin transiently inhibits colorectal cancer cell proliferation as a result of either AMPK activation or increased ROS production. AB - Metformin is a widely used and well-tolerated anti-diabetic drug that can reduce cancer risk and improve the prognosis of certain malignancies. However, the mechanism underlying its anti-cancer effect is still unclear. We studied the anti cancer activity of metformin on colorectal cancer (CRC) by using the drug to treat HT29, HCT116 and HCT116 p53-/- CRC cells. Metformin reduced cell proliferation and migration by inducing cell cycle arrest in the G0/G1 phase. This was accompanied by a sharp decrease in the expression of c-Myc and down regulation of IGF1R. The anti-proliferative action of metformin was mediated by two different mechanisms: AMPK activation and increase in the production of reactive oxygen species, which suppressed the mTOR pathway and its downstream targets S6 and 4EBP1. A reduction in CD44 and LGR5 expression suggested that the drug had an effect on tumour cells with stem characteristics. However, a colony formation assay showed that metformin slowed the cells' ability to form colonies without arresting cell growth, as confirmed by absence of apoptosis, autophagy or senescence. Our finding that metformin only transiently arrests CRC cell growth suggests that efforts should be made to identify compounds that combined with the biguanide can act synergistically to induce cell death. PMID- 29167575 TI - Nutritional assessment of critically ill patients: validation of the modified NUTRIC score. AB - BACKGROUND/OBJECTIVES: In order to identify critically ill patients with high nutritional risk the modified NUTrition Risk in the Critically ill (mNUTRIC) score was developed. This score aims to identify patients that will benefit from nutritional interventions. Few data are available on its validity. In The Netherlands, the MUST-score, a nutritional assessment tool for non-ICU patients, is commonly used in the ICU. To validate the mNUTRIC-score in Dutch ICU patients and compare its prognostic performance with the MUST-score. SUBJECTS/METHODS: A single-center retrospective cohort study among 475 mechanically ventilated patients. Prognostic performance of the mNUTRIC and MUST-scores were assessed and compared for discriminative abilities for 28-day mortality and prolonged mechanical ventilation (>2 days). RESULTS: The discriminative ability of the mNUTRIC-score for 28-day mortality is (ROC-AUC) 0.768 (95% CI 0.722-0.814) with an associated LR+ of 1.73 (95% CI 1.53-1.95) and LR- of 0.24 (95% CI 0.14-0.39) when comparing low with high (>4) scores. Comparing low with high MUST-scores (>1) a ROC-AUC of 0.513 (95% CI 0.445-0.587) and LR+ of 1.05 (95%CI 0.77-1.45) and LR- of 0.97 (95% CI 0.71-1.17) for mortality were found. The discriminative ability for prolonged ventilation was 0.666 (95% CI 0.616-0.716) and 0.532 (95% CI 0.469-0.594) for the mNUTRIC and MUST-scores, respectively. CONCLUSIONS: The prognostic performance of the mNUTRIC-score for 28-day mortality is fair and comparable to other validation studies. The association with prolonged ventilation was not confirmed by our results. The mNUTRIC-score has better performance than the commonly used MUST-score. Therefore, we suggest abandoning use of the MUST-score and to recommend introduction of the mNUTRIC-score for the nutritional risk assessment of critically ill patients. PMID- 29167574 TI - Structural basis of cholesterol binding by a novel clade of dendritic cell modulators from ticks. AB - Two crystal structures of Japanin, an 18 kDa immune-modulatory lipocalin from the Brown Ear Tick (Rhipicephalus appendiculatus), have been determined at 2.2 and 2.4 A resolution. In both crystal forms the protein is in complex with cholesterol, which sits in a closed pocket at the centre of the lipocalin barrel. Both crystal forms are dimers, which are also observed in solution. Molecular modelling suggests that previously-described members of a tick protein family bearing high sequence homology to Japanin are also likely to bind cholesterol or cholesterol derivatives. PMID- 29167576 TI - The effect of weight change over a 2-year period on inflammatory status in postmenopausal women. AB - BACKGROUND/OBJECTIVES: Body fat distribution has been shown to be a predictor of adhesion molecule and inflammatory marker expression albeit the effect of modest weight change on concentrations of adhesion molecules and inflammatory markers in postmenopausal women are not fully understood. The primary aim was to investigate the effects of weight change on adhesion molecules and inflammatory markers over 24 months in postmenopausal women. SUBJECTS/METHODS: Body composition was assessed in 254 healthy postmenopausal women using dual-energy X-ray absorptiometry (DXA). Adhesion molecules and inflammatory markers were analysed by multiplex ELISA. Participants weight gain/loss at 24 months was defined as any value that was either above/below the weight value recorded at baseline. RESULTS: Postmenopausal women with an average weight loss of 3% had significantly decreased leptin concentrations by 18% at 24 months (P < 0.01). A 4% increase in body weight or a 9% increase in FMI significantly increased intercellular adhesion molecule-1 (ICAM-1), tumour necrosis factor-alpha (TNF-alpha) and leptin concentrations in postmenopausal women at 24 months (P < 0.01). CONCLUSIONS: Modest weight loss in postmenopausal women has a lowering effect on leptin concentrations over 24 months which may improve inflammatory status whilst modest weight gain increases ICAM-1, leptin and TNF-alpha, markers which are associated with a pro-inflammatory state and vascular complications. PMID- 29167577 TI - Association of maternal breast milk and serum levels of macronutrients, hormones, and maternal body composition with infant's body weight. AB - BACKGROUND/OBJECTIVES: This study was aimed to investigate the association of maternal serum and breast-milk levels of macronutrients, hormones, growth factors, and maternal body composition with infant's body weight. SUBJECTS/METHODS: Eighty mother-infant pairs comprised 40 with overweight or obese infant and 40 with normal-weight infant were enrolled in this study. The level of ghrelin, Leptin, adiponectin, EGF, and IGF1 in plasma and breast milk were assessed. Daily breast milk intake and macronutrient concentration along with anthropometric indices of mother-infant pairs were also assessed. RESULTS: No significant differences were observed in concentrations of serum hormones between two groups (p > 0.05). However, hormones levels in maternal serum were higher than those in breast milk. A significant positive correlation was found between serum EGF and ghrelin (r = 0.57, p = 0 < 0001). Higher IGF1 in serum showed a significant association with its milk counterpart (r = 0.37). Current mother's weight was associated with infant's weight at the 2nd and 6th month (B = 0.023 p = 0.04, B = 0.055 p = 0.005). The breast-milk macronutrient content was not comparable between two groups. However, the average daily breast milk consumption in obese infants was higher than normals (p = 0.001). Milk EGF and leptin were related to a decrease of 59% and 46% the odds of obese infant development, respectively. There was a significant association of milk EGF and ghrelin with birth weight (B = -0.19, p = 0.04 and B = -0.2, p = 0.04, respectively), and also serum leptin with infant's body weight at the 6th month. CONCLUSIONS: Our findings provide a positive association of maternal weight, daily breast milk intake, EGF, and ghrelin with infant's body weight. PMID- 29167578 TI - Comparative Genomics of Color Morphs In the Coral Montastraea cavernosa. AB - Montastraea cavernosa is a common coral in the Caribbean basin found in several color morphs. To investigate the causes for brown and orange morphs we undertook a genomics approach on corals collected at the same time and depth in the Bahamas. The coral holobiont includes the host, symbiotic dinoflagellates (Symbiodinium spp.), and a diverse microbiome. While the coral host showed significant genetic differentiation between color morphs both the composition of the Symbiodinium spp. communities and the prokaryotic communities did not. Both targeted and global gene expression differences in the transcriptome of the host show no difference in fluorescent proteins while the metatranscriptome of the microbiome shows that pigments such as phycoerythrin and orange carotenoid protein of cyanobacterial origin are significantly greater in orange morphs, which is also consistent with the significantly greater number of cyanobacteria quantified by 16S rRNA reads and flow cytometry. The microbiome of orange color morphs expressed significantly more nitrogenase (nifH) transcripts consistent with their known ability to fix nitrogen. Both coral and Symbiodinium spp. transcriptomes from orange morphs had significantly increased expression of genes related to immune response and apoptosis, which may potentially be involved in maintaining and regulating the unique symbiont population in orange morphs. PMID- 29167579 TI - The First 1000 Days of Life Factors Associated with "Childhood Asthma Symptoms": Brisa Cohort, Brazil. AB - This prospective study used data from the BRISA Cohort, Sao Luis, Brazil (n = 1140) and analyzed associations between environmental factors up to the first 1000 days of life and "Childhood Asthma Symptoms". "Childhood Asthma Symptoms" was a latent variable based on the number of wheezing episodes, emergency care visit due to wheezing, diagnosis of asthma and diagnosis of rhinitis. A theoretical model that included prenatal factors (socioeconomic status, pregestational body mass index-BMI, soft drink and junk food consumption), birth factors (gestational age, smoking and diseases during pregnancy, birth weight and type of delivery), first year of life factors (breastfeeding, environmental aeroallergens and respiratory diseases) and BMI z-score in the second year of life, was analyzed by structural equation modeling. High pregestational BMI, high soft drink consumption, cesarean section without labor, chill in the first three months of life, carpeted floor and child's exposure to tobacco were associated with higher values of "Childhood Asthma Symptoms". In contrast, high birth weight, breastfeeding and infant's age were associated with lower values of "Childhood Asthma Symptoms". These findings support the hypothesis that environmental factors that are present before conception and up to the first 1000 days of life are associated with asthma. PMID- 29167580 TI - Pyridoxamine improves survival and limits cardiac dysfunction after MI. AB - Advanced glycation end products (AGEs) play a key role in the progression of heart failure. Whether treatments limiting AGEs formation would prevent adverse left ventricular remodeling after myocardial infarction (MI) remain unknown. We investigated whether pyridoxamine (PM) could limit adverse cardiac outcome in MI. Rats were divided into MI, MI + PM and Sham. Echocardiography and hemodynamic parameters were used to assess cardiac function 8 weeks post-surgery. Total interstitial collagen, collagen I and collagen III were quantified using Sirius Red and polarized light microscopy. PM improved survival following LAD occlusion. Pre-treatment with PM significantly decreased the plasma AGEs levels. MI rats treated with PM displayed reduced left ventricular end-diastolic pressure and tau compared to untreated MI rats. Deformation parameters were also improved with PM. The preserved diastolic function was related to the reduced collagen content, in particular in the highly cross-linked collagen type I, mainly in the peri-infarct region, although not via TGF-beta1 pathway. Our data indicate that PM treatment prevents the increase in AGEs levels and reduces collagen levels in a rat model of MI, resulting in an improved cardiac phenotype. As such, therapies targeting formation of AGEs might be beneficial in the prevention and/or treatment of maladaptive remodeling following MI.

AB - Glucokinase is one of the promising targets for glucose-lowering agents, and the development of GK activators are now considered as one of the most promising strategies for the treatment of type 2 diabetes mellitus. In this work, a series of novel symmetric molecular constructs, in which two pyridoxine moieties are connected via sulfur-containing linkers, have been synthesized and tested in vitro for glucokinase activation potential. The enzyme activation rates by two most active compounds at 100 MUM (~150% and 130%) were comparable to that of the reference agent PF-04937319 (~154%). Both leading compounds demonstrated low cytotoxicity and excellent safety profile in acute toxicity experiment in rats after oral administration with LD50 exceeding 2000 mg/kg of body weight. Binding mode of the active compounds in comparison with the reference agent was studied using molecular docking. The leading compounds represent viable preclinical candidates for the treatment of type 2 diabetes mellitus, as well as a promising starting point for the design of structural analogs with improved activity. PMID- 29167584 TI - Performance Monitoring of Chilled-Water Distribution Systems Using HVAC-Cx. AB - In this research we develop, test, and demonstrate the newest extension of the software HVAC-Cx (NIST and CSTB 2014), an automated commissioning tool for detecting common mechanical faults and control errors in chilled-water distribution systems (loops). The commissioning process can improve occupant comfort, ensure the persistence of correct system operation, and reduce energy consumption. Automated tools support the process by decreasing the time and the skill level required to carry out necessary quality assurance measures, and as a result they enable more thorough testing of building heating, ventilating, and air-conditioning (HVAC) systems. This paper describes the algorithm, developed by National Institute of Standards and Technology (NIST), to analyze chilled-water loops and presents the results of a passive monitoring investigation using field data obtained from BACnet(r) (ASHRAE 2016) controllers and presents field validation of the findings. The tool was successful in detecting faults in system operation in its first field implementation supporting the investigation phase through performance monitoring. Its findings led to a full energy retrocommissioning of the field site. PMID- 29167583 TI - The influence of curvature on the properties of the plasma membrane. Insights from atomistic molecular dynamics simulations. AB - In this work we conduct a systematic analysis of the influence of curvature on various properties of a realistic model of mammalian plasma membrane with asymmetric lipid content of monolayers and a realistic concentration of cholesterol. In order to do this we developed new technique for simulating membranes with the global membrane curvature restricted to any desirable value while keeping free lateral diffusion of the lipids and without introducing artifacts or perturbing the membrane structure. We show that the thickness of the hydrophobic core of the concave monolayer decreases by approximately 1.3 A in comparison to that of the flat membrane, while the thickness of the convex monolayer does not change. The order parameter of the lipid tails decreases significantly in the certain layers of the curved membrane. The area per lipid increases in the convex monolayer and decreases in the concave monolayer. The cholesterol inclination angle decreases when the curvature of a particular monolayer changes from concave to convex. The amount of cholesterol in the minor fraction located between the membrane leaflets is zero in the membrane with positive curvature and increases to 1.7% in the flat membrane and to 2.5% in the membrane with negative curvature.

AB - The ability to interpret facial expressions of others is one of the more important abilities possessed by humans. However, is it possible for humans to accurately interpret the facial expressions of another species of primate, namely rhesus monkeys (Macaca mulatta)? We investigated this possibility by taking digital photos of four rhesus monkeys housed either singly or socially and allowing thirty-one participants to judge these photographs as representing either a happy, sad, or neutral monkey. Results indicated that the photographs of monkeys that were socially housed were more likely to be rated as happy or neutral than were photographs of singly housed monkeys. We suggest that these results imply important parallels between the perception of human and nonhuman primate facial expressions as well as introduce a potential new method for assessing nonhuman primate well-being. PMID- 29167586 TI - Promoting Pluralism in Counselling: an Untapped Source of Relational Mapping as Therapeutic Process. AB - This paper discusses the merits of pluralism in practice. It argues for a wider recognition of creative and integrative approaches, such as those used in the field of children's geographies (involving places and spaces), as a way of unlocking practitioner potential and innovation. By re-thinking child and human development, viewing it as socially, culturally and philosophically bound, through the proposed concept of 'vectors of entanglements', the author seeks to demonstrate and encourage the application of hybrid approaches across multi disciplinary fields. Through the use of diagramming and mapping the interconnectedness of relationships across space and place, the therapeutic process is brought to life to encourage practitioners to explore the 'invisible' threads that constitute significant meanings to clients.

AB - This paper adds to the growing body of research examining the experiences of youth aging out of the child welfare system. Through a comparison of youth aging out with two other groups of child welfare-involved youth-those whose families received child welfare services but were never placed out of home and those who were in out-of-home placement but did not age out-it presents a profile of their care careers and other system involvement (e.g., mental health, justice system). Analyses indicate that young people aging out of care have experienced significant amounts of time in out-of-home placement, a great deal of placement instability, and high levels of other system involvement. In general, their involvement is more extensive than that of the two comparison groups. However, the justice system involvement of youth who experienced out-of-home placement but did not age out is just as high as that of youth who have aged out. This finding highlights the importance of devoting resources not only to youth aging out of care but also to similarly-aged young people with prior child welfare involvement. PMID- 29167590 TI - Dynamic Latent Trait Models with Mixed Hidden Markov Structure for Mixed Longitudinal Outcomes. AB - We propose a general Bayesian joint modeling approach to model mixed longitudinal outcomes from the exponential family for taking into account any differential misclassification that may exist among categorical outcomes. Under this framework, outcomes observed without measurement error are related to latent trait variables through generalized linear mixed effect models. The misclassified outcomes are related to the latent class variables, which represent unobserved real states, using mixed hidden Markov models (MHMM). In addition to enabling the estimation of parameters in prevalence, transition and misclassification probabilities, MHMMs capture cluster level heterogeneity. A transition modeling structure allows the latent trait and latent class variables to depend on observed predictors at the same time period and also on latent trait and latent class variables at previous time periods for each individual. Simulation studies are conducted to make comparisons with traditional models in order to illustrate the gains from the proposed approach. The new approach is applied to data from the Southern California Children Health Study (CHS) to jointly model questionnaire based asthma state and multiple lung function measurements in order to gain better insight about the underlying biological mechanism that governs the inter-relationship between asthma state and lung function development.

AB - We investigate the applicability of large-scale Granger Causality (lsGC) for extracting a measure of multivariate information flow between pairs of regional brain activities from resting-state functional MRI (fMRI) and test the effectiveness of these measures for predicting a disease state. Such pairwise multivariate measures of interaction provide high-dimensional representations of connectivity profiles for each subject and are used in a machine learning task to distinguish between healthy controls and individuals presenting with symptoms of HIV Associated Neurocognitive Disorder (HAND). Cognitive impairment in several domains can occur as a result of HIV infection of the central nervous system. The current paradigm for assessing such impairment is through neuropsychological testing. With fMRI data analysis, we aim at non-invasively capturing differences in brain connectivity patterns between healthy subjects and subjects presenting with symptoms of HAND. To classify the extracted interaction patterns among brain regions, we use a prototype-based learning algorithm called Generalized Matrix Learning Vector Quantization (GMLVQ). Our approach to characterize connectivity using lsGC followed by GMLVQ for subsequent classification yields good prediction results with an accuracy of 87% and an area under the ROC curve (AUC) of up to 0.90. We obtain a statistically significant improvement (p<0.01) over a conventional Granger causality approach (accuracy = 0.76, AUC = 0.74). High accuracy and AUC values using our multivariate method to connectivity analysis suggests that our approach is able to better capture changes in interaction patterns between different brain regions when compared to conventional Granger causality analysis known from the literature.

AB - Clinically Isolated Syndrome (CIS) is often considered to be the first neurological episode associated with Multiple sclerosis (MS). At an early stage the inflammatory demyelination occurring in the CNS can manifest as a change in neuronal metabolism, with multiple asymptomatic white matter lesions detected in clinical MRI. Such damage may induce topological changes of brain networks, which can be captured by advanced functional MRI (fMRI) analysis techniques. We test this hypothesis by capturing the effective relationships of 90 brain regions, defined in the Automated Anatomic Labeling (AAL) atlas, using a large-scale Granger Causality (lsGC) framework. The resulting networks are then characterized using graph-theoretic measures that quantify various network topology properties at a global as well as at a local level. We study for differences in these properties in network graphs obtained for 18 subjects (10 male and 8 female, 9 with CIS and 9 healthy controls). Global network properties captured trending differences with modularity and clustering coefficient (p<0.1). Additionally, local network properties, such as local efficiency and the strength of connections, captured statistically significant (p<0.01) differences in some regions of the inferior frontal and parietal lobe. We conclude that multivariate analysis of fMRI time-series can reveal interesting information about changes occurring in the brain in early stages of MS.

AB - Satellite instruments operating in the reflective solar wavelength region require accurate and precise determination of the Bidirectional Reflectance Distribution Functions (BRDFs) of the laboratory and flight diffusers used in their pre-flight and on-orbit calibrations. This paper advances that initial work and presents a comparison of spectral Bidirectional Reflectance Distribution Function (BRDF) and Directional Hemispherical Reflectance (DHR) of Spectralon, a common material for laboratory and on-orbit flight diffusers. A new measurement setup for BRDF measurements from 900 nm to 2500 nm located at NASA Goddard Space Flight Center (GSFC) is described. The GSFC setup employs an extended indium gallium arsenide detector, bandpass filters, and a supercontinuum light source. Comparisons of the GSFC BRDF measurements in the shortwave infrared (SWIR) with those made by the National Institute of Standards and Technology (NIST) Spectral Tri-function Automated Reference Reflectometer (STARR) are presented. The Spectralon sample used in this study was 2 inch diameter, 99% white pressed and sintered Polytetrafluoroethylene (PTFE) target. The NASA/NIST BRDF comparison measurements were made at an incident angle of 0 degrees and viewing angle of 45 degrees . Additional BRDF data not compared to NIST were measured at additional incident and viewing angle geometries and are not presented here. The total combined uncertainty for the measurement of BRDF in the SWIR range made by the GSFC scatterometer is less than 1% (k = 1). This study is in support of the calibration of the Radiation Budget Instrument (RBI) and Visible Infrared Imaging Radiometer Suit (VIIRS) instruments of the Joint Polar Satellite System (JPSS) and other current and future NASA remote sensing missions operating across the reflected solar wavelength region. PMID- 29167594 TI - Ultrahigh-resolution multicolor colocalization of single fluorescent nanocrystals. AB - A new method for in vitro and possibly in vivo ultrahigh-resolution colocalization and distance measurement between biomolecules is described, based on semiconductor nanocrystal probes. This ruler bridges the gap between FRET and far-field (or near-field scanning optical microscope) imaging and has a dynamic range from few nanometers to tens of micrometers. The ruler is based on a stage scanning confocal microscope that allows the simultaneous excitation and localization of the excitation point-spread-function (PSF) of various colors nanocrystals while maintaining perfect registry between the channels. Fit of the observed diffraction and photophysics-limited images of the PSFs with a two dimensional Gaussian allows one to determine their position with nanometer accuracy. This new high-resolution tool opens new windows in various molecular, cell biology and biotechnology applications. PMID- 29167595 TI - Seasonal variations in C:N:Si:Ca:P:Mg:S:K:Fe relationships of seston from Norwegian coastal water: Impact of extreme offshore forcing during winter-spring 2010. AB - The aim of this study was to reveal the relative content of C, N, Ca, Si, P, Mg, K, S and Fe in seston particles in Norwegian coastal water (NCW), and how it relates to biological and hydrographic processes during seasonal cycles from October 2009-March 2012. The following over all stoichiometric relationship for the time series was obtained: C66N11Si3.4Ca2.3P1Mg0.73S0.37K0.35Fe0.30, which is novel for marine waters. A record-breaking (187-year record) negative North Atlantic Oscillation (NAO) index caused extreme physical forcing on the Norwegian Coastal Current Water (NCCW) during the winter 2009-2010, and the inflow and upwelling of saline Atlantic water (AW) in the fjord was thus extraordinary during late spring-early summer in 2010. The element concentrations in fjord seston particles responded strongly to this convection, revealed by maximum values of all elements, except Fe, exceeding average values with 10.8 * for Ca, 9.3 for K, 5.3 for S, 5.1 for Mg, 4.6 for Si, 4.0 for P, 3.8 for C, and 3.3 for N and Fe. This indicates that the signature of the Atlantic inflow was roughly two times stronger for Ca and K than for the others, probably connected with peaks in coccolithophorids and diatoms. There is, however, 1.5 * more of Si than Ca contained in the seston, which could be due to a stronger dominance of diatoms than coccolithophorids, confirming their environmental fitness. In total our data do not indicate any severe nutrient limitation with respect to N, P and Fe, but accumulation of iron by Fe-sequestering bacteria might at times reduce the availability of the dissolved Fe-fraction. There is a high correlation between most of the measured elements, except for Ca, which together with Fe only weakly correlated with the other elements. It is to be expected that environmental alterations in NCW related to climate change will influence the seston elemental composition, but the full effect of this will be strongly dependent on the future dominance of the high pressure versus low pressure systems (i.e. NAO index), since they are key regulators for the direction of wind driven vertical convection (i.e. upwelling or downwelling). Changes in stratification, temperature, light, pH (ocean acidification), CaCO3 concentrations (carbon pump) and availability of nutrients in the euphotic zone (biogeochemical cycling) are essential for the future dominance of coccolithophorids versus diatoms. PMID- 29167596 TI - Vocal foragers and silent crowds: context-dependent vocal variation in Northeast Atlantic long-finned pilot whales. AB - Abstract: Vocalisations form a key component of the social interactions and foraging behaviour of toothed whales. We investigated changes in calling and echolocation behaviour of long-finned pilot whales between foraging and non foraging periods, by combining acoustic recordings and diving depth data from tagged individuals with concurrent surface observations on social behaviour of their group. The pilot whales showed marked vocal variation, specific to foraging and social context. During periods of foraging, pilot whales showed more vocal activity than during non-foraging periods (rest, travel). In addition to the expected increase in echolocation activity, call rates also increased, suggesting that pilot whales communicate more during foraging. Furthermore, calls with multiple inflections occurred more often immediately before and after foraging dives and during the early descent and late ascent phases of foraging dives. However, these calls were almost never detected at diving depths of the tagged whale beyond 350 m. Calls with no or few inflections were produced at all times, irrespective of diving depth of the tagged whale. We discuss possible explanations for the distinct vocal variation associated with foraging periods. In addition, during non-foraging periods, the pilot whales were found to be more silent (no calling or echolocation) in larger, more closely spaced groups. This indicates that increased levels of social cohesion may release the need to stay in touch acoustically. Significance statement: Social toothed whales rely on vocalisations to find prey and interact with conspecifics. Species are often highly vocal and can have elaborate call repertoires. However, it often remains unclear how their repertoire use correlates to specific social and behavioural contexts, which is vital to understand toothed whale foraging strategies and sociality. Combining on-animal tag recordings of diving and acoustic behaviour with observations of social behaviour, we found that pilot whales produce more calls during foraging than during non-foraging periods. Moreover, highly inflected calls were closely associated to the periods around and during foraging dives. This indicates enhanced communication during foraging, which may, for example, enable relocation of conspecifics or sharing of information. Whales reduced their vocal activity (calling and echolocation) at increased levels of social cohesion, indicating that in certain behavioural contexts, closer association (i.e. more closely spaced) may release the need to stay in touch acoustically.

Organized by a life course framework, this review covers the state of contemporary research on adolescents' physical, psychological, interpersonal, and institutional pathways; how these pathways connect within primary ecological contexts; and how they relate to broader patterns of societal stratification and historical change. Looking forward, it also emphasizes three future challenges/opportunities, including efforts to illuminate biosocial processes, link adolescence to other life stages, and account for the influence of major social changes (e.g., the new media). PMID- 29167598 TI - The relationship between birch pollen, air pollution and weather types and their effect on antihistamine purchase in two Swedish cities. AB - Exposure to elevated air pollution levels can aggravate pollen allergy symptoms. The aim of this study was to investigate the relationships between airborne birch (Betula) pollen, urban air pollutants NO2, O3 and PM10 and their effects on antihistamine demand in Gothenburg and Malmo, Sweden, 2006-2012. Further, the influence of large-scale weather pattern on pollen-/pollution-related risk, using Lamb weather types (LWTs), was analysed. Daily LWTs were obtained by comparing the atmospheric pressure over a 16-point grid system over southern Sweden (scale ~3000 km). They include two non-directional types, cyclonic (C) and anticyclonic (A) and eight directional types depending on the wind direction (N, NE, E...). Birch pollen levels were exceptionally high under LWTs E and SE in both cities. Furthermore, LWTs with dry and moderately calm meteorological character (A, NE, E, SE) were associated with strongly elevated air pollution (NO2 and PM10) in Gothenburg. For most weather situations in both cities, simultaneously high birch pollen together with high air pollution had larger over-the-counter (OTC) sales of antihistamines than situations with high birch pollen alone. LWTs NE, E, SE and S had the highest OTC sales in both cities. In Gothenburg, the city with a higher load of both birch pollen and air pollution, the higher OTC sales were especially obvious and indicate an increased effect on allergic symptoms from air pollution. Furthermore, Gothenburg LWTs A, NE, E and SE were associated with high pollen and air pollution levels and thus classified as high-risk weather types. In Malmo, corresponding high-risk LWTs were NE, E, SE and S. Furthermore, occurrence of high pollen and air pollutants as well as OTC sales correlated strongly with vapour pressure deficit and temperature in Gothenburg (much less so in Malmo). This provides evidence that the combination of meteorological properties associated with LWTs can explain high levels of birch pollen and air pollution. Our study shows that LWTs represent a useful tool for integrated daily air quality forecasting/warning. PMID- 29167599 TI - Inhalable dust, endotoxins and (1-3)-beta-d-glucans as indicators of exposure in waste sorting plant environment. AB - The aim of the study was to assess the levels of inhalable dust, endotoxins and (1-3)-beta-d-glucans as agents harmful to the respiratory tract of workers of municipal waste sorting plants and interaction between these agents based on the measurements taken in two plants with different processing capacities. The study was conducted in summer season in two waste sorting plants (WSPs) differing in processing capacity. Samples of bioaerosol for inhalable dust (gravimetric method), endotoxins (LAL test in kinetic, chromogenic version) and (1-3)-beta-d glucans (Glucatell test in kinetic version) were collected from 42 sorting workers using individual aspirators with glass fiber filters during the work shift. Average geometric concentrations (geometric standard deviation; min-max) of inhalable dust, endotoxins and (1-3)-beta-d-glucans were: WSP1: 1.7 mg m-3 (2.2; 0.6-6.9 mg m-3); 15.9 ng m-3 (2.1; 5.4-78.9 ng m-3), 55.1 ng m-3 (1.8; 20.7 188.6 ng m-3) and WSP2: 0.8 mg m-3 (2.2; 0.2-3.8 mg m-3), 9.8 ng m-3 (2.4; 1.6 29.7 ng m-3), 45.0 ng m-3 (3.2, 5.7-212.9 ng m-3), respectively. A significantly higher concentration of inhalable dust was recorded in WSP1 with bigger processing capacity compared to WSP2 (less processing capacity). Significant (p < 0.05) and very high correlations (Spearman rank R > 0.7) were found between the concentrations of all analyzed harmful agents. Processing capacity of waste sorting plants differentially affects the concentrations of inhalable dust, whereas concentrations of endotoxins and glucans are less clearly affected. This suggests that relative concentrations of endotoxin and glucan are depending on the waste sorting capacity. PMID- 29167600 TI - Allergenic Asteraceae in air particulate matter: quantitative DNA analysis of mugwort and ragweed. AB - Mugwort (Artemisia vulgaris) and ragweed (Ambrosia artemisiifolia) are highly allergenic Asteraceae. They often cause pollen allergies in late summer and fall. While mugwort is native to Europe, ragweed reached Europe as a neophyte from North America about 150 years ago and continued spreading ever since. To understand possible relationships between the spread of ragweed, its abundance in air, and to judge possible health risks for the public, we quantified ragweed DNA in inhalable fine as well as in coarse air particulate matter. Mugwort was chosen for comparison, as it is closely related to ragweed and grows in similar, though mainly not identical, habitats but is native to Germany. The DNA quantification was performed on atmospheric aerosol samples collected over a period of 5 years in central Europe. The DNA concentrations were highest during the characteristic pollination periods but varied greatly between different years. In the inhalable fine particle fraction, ragweed exceeds the mugwort DNA concentration fivefold, while the coarse particle fraction, bearing intact pollen grains, contains more mugwort than ragweed DNA. The higher allergenic potential of ragweed might be linked to the humidity or long-range transport-induced bursting of ragweed pollen into smaller allergenic particles, which may reach the lower airways and cause more intense allergic reactions. Airborne ragweed DNA was detected also outside the local pollination periods, which can be explained by atmospheric long-range transport. Back-trajectory analyses indicate that the air masses containing ragweed DNA during winter had originated in regions with milder climate and large ragweed populations (Southern France, Carpathian Basin). PMID- 29167601 TI - Tectonic evolution and paleokarstification of carbonate rocks in the Paleozoic Tarim Basin. AB - Thick carbonate rocks were developed in the depression of the Tarim craton during the Cambrian-Middle Ordovician periods. The compressional tectonic movement during the Middle Caledonian-Hercynian created the paleouplifts, which became the base for the paleokarst in the Ordovician carbonate rocks. Based on the large quantity of seismic, drilling, and geological outcrop data, this study analyzed the paleokarst development in relation to the multi-stage tectonic movements in the Paleozoic Era and different stages of karstification and hypothesized paleogeomorphology and paleokarst water system of those stages. Fractures from the tectonic movements in the carbonate and non-carbonate rocks were essential for water cycle, and therefore, the karst development in deep carbonate rocks. Paleokarsts in the Tarim Basin can be classified into four major types based on the paleogeomorphology, degree of karstification, and the layering, i.e., Tahe type, gentle hill type, high steep hill type, and covered-semi-open type. Relatively, the Tahe type was mostly on hill slopes and had the strongest karstification, the gentle hill type often located in the plain areas or basin bottoms and had least karstification, the high steep hill type was controlled by faults and had medium karstification, the semi-open type was controlled by precipitation and hydraulic gradient, and fracture passages and karst caves were mostly developed along major fractures. Overall, the paleokarsts of the Ordovician carbonate rocks in the Tarim Basin can be characterized by long geologic history, multiple development stages, deep burial depth, and various karst types. PMID- 29167602 TI - Rapid, Reversible Release from Thermosensitive Liposomes Triggered by Near-Infra Red Light. AB - We present a novel drug carrier consisting of plasmonic hollow gold nanoshells (HGN) chemically tethered to liposomes made temperature sensitive with lysolipids (LTSL). Continuous-wave irradiation by physiologically friendly near infra-red light at 800 nm for 2.5 minutes at laser intensities an order of magnitude below that known to damage skin generates heating localized to the liposome membrane. The heating increases the liposome permeability in an irradiation dose-dependent, but reversible manner, resulting in rapid release of small molecules such as the self-quenching dye carboxyfluorescein or the chemotherapeutic doxorubicin, without raising the bulk temperature. The local rise in nanoshell temperature under laser irradiation was inferred by comparing dye release rates from the LTSL via bulk heating to that induced by irradiation. Laser-irradiation of LTSL enables precise control of contents release with low temperature gradients confined to areas irradiated by the laser focus. The combined effects of rapid local release and localized hyperthermia provide a synergistic effect as shown by a near doubling of androgen resistant PPC-1 prostate cancer cell toxicity compared to the same concentration of free doxorubicin. PMID- 29167603 TI - On-demand generation and mixing of liquid-in-gas slugs with digitally programmable composition and size. AB - Microscopic droplets or slugs of mixed reagents provide a convenient platform for performing large numbers of isolated biochemical or chemical reactions for many screening and optimization applications. Myriad microfluidic approaches have emerged for creating droplets or slugs with controllable size and composition, generally using an immiscible carrier fluid to assist with the formation or merging processes. We report a novel device for generation of liquid slugs in air when the use of a carrier liquid is not compatible with the application. The slug generator contains two adjacent chambers, each of which has a volume that can be digitally adjusted by closing selected microvalves. Reagents are filled into the two chambers, merged together into a contiguous liquid slug, ejected at the desired time from the device using gas pressure, and mixed by flowing in a downstream channel. Programmable size and composition of slugs is achieved by dynamically adjusting the volume of each chamber prior to filling. Slug formation in this fashion is independent of fluid properties and can easily be scaled to mix larger numbers of reagents. This device has already been used to screen monomer ratios in supramolecular nanoparticle assembly and radiolabeling conditions of engineered antibodies, and here we provide a detailed description of the underlying device.

AB - The lumbar facet joints have been implicated as one of the causes of low-back pain syndromes. About 15-40% of patients who presented with chronic low-back pain was attributed to lumbar facet joint pain. The purpose of this study was to analyse whether radiofrequency denervation is better than SHAM procedure in treating chronic low-back pain caused by lumbar zygapophysial joints pathology. From the four identified randomised control trials, there is conflicting evidence at an intermediate 3-6-month stage, however; one study demonstrates statistical significance of radiofrequency denervation at 3 months. Longer-term follow-up is needed to prove the efficacy of radiofrequency denervation technique.

AB - Septic Arthritis is an orthopedic emergency that requires prompt diagnosis and treatment. Staphylococcus aureus is the most common pathogen causing septic arthritis. This review seeks to describe clinical characteristics and outcomes associated with patients with methicillin-resistant (MRSA) vs. methicillin sensitive staphylococcus aureus (MSSA) septic arthritis. The review showed that those infected with MRSA were older, had more chronic medical conditions, and higher values of inflammatory markers. MRSA septic arthritis was also associated with more complications, longer duration of antibiotics, and increased mortality. Thus, health care providers should maintain a high index of suspicion, diagnose, and treat aggressively to prevent adverse outcomes. PMID- 29167606 TI - Results of operative 4-in-1 patella realignment in children with recurrent patella instability. AB - Purpose: Recurrent patellar instability is a cause of knee dysfunction, limitation and pain for children. If nonoperative treatment fails to stabilise the patella, operative realignment and stabilisation have been advocated. Operative techniques in the paediatric population must preserve physeal growth while ensuring stability. We aimed to determine the outcome of children and adolescents who underwent a 4-in-1 patellar realignment (lateral release, medial reefing, Insall tube realignment and Roux-Goldthwaite patella ligament transfer). Methods: Consecutive skeletally immature patients operated in our institution were included in the study. A total of 16 operated knees in 12 patients were recruited. All patients underwent the same procedure after attempting a minimum period of 6 months of non-operative treatment with unsatisfactory results. The main outcome measured was recurrent dislocations. Functional outcomes were assessed using the Kujala score and the Paediatric form of the International Knee Documentation Committee Subjective Knee Form (Pedi-IKDC). Results: Patients were followed up for a minimum of 3 years. None of the patients sustained further patella dislocations following the operation. In 3 cases, minor patellar maltracking was noted post-operatively but all 3 remained asymptomatic. Three patients had a small area of numbness lateral to the operative incision, which coincided with hypertrophic scarring. There was one case of superficial wound infection. The mean Kujala score was 83.4 +/- 11.47 and the mean Pedi-IKDC was 79.5 +/- 12.56 at the latest follow-up (minimum of 36 months). Conclusions: The 4 in-1 patellar realignment is a good procedure in paediatric and adolescent patients with recurrent patella instability. Satisfactory results were observed with a minimal complication and redislocation rate in our series. PMID- 29167607 TI - Impact of Intra-Aortic Balloon Counterpulsation on Prognosis of Patients with Acute Myocardial Infarction: A Meta-Analysis. AB - Background: This study aimed to evaluate the impact of intra-aortic balloon counterpulsation (IABP) on the prognosis of patients with acute myocardial infarction (AMI). Methods: We identified and included in this study AMI cases treated with IABP from January 1970 to May 2014. For statistical analysis, we utilized RevMan 5.0 software. Results: Fourteen RCTs with a total population of 2538 were included in this study. The in-hospital and 30-day mortality rate in the IABP group was not significantly lower than those in the non-IABP group. Subgroup analysis according to the type of revascularization, OR values of TT subgroup, PCI subgroup, and CABG subgroup were 0.64 (95% CI 0.25-1.61, p = 0.34), 0.85 (95% CI 0.65-1.11, p = 0.23) and 0.46 (95% CI 0.13-1.63, p = 0.23). And OR values of AMI patients in the before and after PCI subgroup were 0.43 (95% CI 0.21-0.91, p = 0.03) and 1.36 (95% CI 0.76-2.41, p = 0.30). The 6-month mortality in the IABP group was not significantly lower than that in the non-IABP group. And OR values of 6-month mortalities of the before and after PCI subgroup were 0.47 (95% CI 0.26-0.86, p = 0.01) and 1.40 (95% CI 0.57-3.45, p = 0.47). Conclusions: IABP did not reduce the in-hospital and 30-day mortality of AMI patients, and did not reduce the 6-month mortality. But IABP used in AMI patients before PCI was associated not only with reduced in-hospital and 30-day mortality, but also reduced 6-month mortality.

AB - As medical research techniques and quality have improved, it is apparent that cardiovascular problems could be better resolved by more strict experiment design. In fact, substantial time and resources should be expended to fulfill the requirements of high quality studies. Many worthy ideas and hypotheses were unable to be verified or proven due to ethical or economic limitations. In recent years, new and various applications and uses of databases have received increasing attention. Important information regarding certain issues such as rare cardiovascular diseases, women's heart health, post-marketing analysis of different medications, or a combination of clinical and regional cardiac features could be obtained by the use of rigorous statistical methods. However, there are limitations that exist among all databases. One of the key essentials to creating and correctly addressing this research is through reliable processes of analyzing and interpreting these cardiologic databases. PMID- 29167610 TI - The Difference on Features of Fragmented QRS Complex and Influences on Mortality in Patients with Acute Coronary Syndrome. AB - Objectives: To investigate whether the fragmented QRS (fQRS) complexes can be used to distinguish patients with early non-ST elevation myocardial infarction (NSTEMI) from those with unstable angina (UA). Background: fQRS complex has been found to be linked to myocardial infarction and cardiac death. Methods: The clinical data of 302 patients who had been diagnosed with coronary artery disease were retrospectively reviewed. Incidence of fQRS complex within 48 h of presentation was analyzed and patients with acute myocardial infarction (AMI) (n = 240) were followed up by telephone interviews for a mean of 61.47 (range, 59.60 63.35) months. Results: Patients with NSTEMI exhibited higher incidence of fQRS than those with UA (p = 0.047). The incidence of fQRS in the inferior wall leads was significantly higher than that of other leads in patients with anterior wall infarction (p < 0.05). Kaplan-Meier analysis revealed a higher mortality rate in AMI patients with fQRS compared to non-fQRS patients (p = 0.001). Conclusions: Presence of fQRS complexes within 48 hours of presentation may be used to differentiate NSTEMI patients from UA patients. fQRS may also be used as a survival predictor for patients with AMI.

PMID- 29167612 TI - The Value of CHA2DS2VASC Score in Predicting All-Cause Mortality in Patients with ST-Segment Elevation Myocardial Infarction Who Have Undergone Primary Percutaneous Coronary Intervention. AB - Background: Acute coronary syndrome is the most common cause of cardiac morbidity and death. Various scoring systems have been developed in order to identify patients who are at risk for adverse outcome and may benefit from more aggressive and effective therapies. Objectives: This study was designed to evaluate the CHA2DS2VASC score as a predictor of mortality inpatients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention (p PCI). Methods: We evaluated 300 patients diagnosed with ST-elevation myocardial infarction who underwent p-PCI and calculated their CHA2DS2VASC scores. According to their CHA2DS2VASC scores, patients were divided into three groups. Group 1: 0 1 points (n = 101), Group 2: 2-3 points (n = 129), and Group 3: 4-9 points (n = 70). The mean, median and minimum duration of follow-up were 21.7 +/- 9.4, 21, and 12 months, respectively. All-cause mortality was defined as the primary endpoint of the study. Results: All-cause mortality was 4% in Group 1, 8.5% in Group 2 and 27.1% in Group 3 respectively. Kaplan-Meier analysis showed that Group 3 (CHA2DS2VASC >= 4) had a significantly higher incidence of death [p (log rank) < 0.001]. In ROC analysis, AUC values for in hospital, 12-month and long term mortality were 0.88 (0.77-0.99 95% CI), 0.82 (0.73-0.92 95% CI) and 0.79 (0.69-0.88 95% CI), respectively. Conclusions: CHA2DS2VASC score can be used for predicting both in-hospital, 12-month and long-term mortality in patients with STEMI who have undergone p-PCI.

AB - Background: Coronary artery perforation (CAP) during percutaneous coronary intervention (PCI) is associated with increased mortality. Polytetrafluoroethylene covered stents (CS) are an effective approach to treat CAP, but data regarding elderly patients requiring CS implantation for CAP are limited. The aim of this study is to report clinical data for elderly CAP patients undergoing CS implantation during PCI. Methods: Nineteen consecutive elderly patients (>= 65 years) undergoing CS implantation due to PCI-induced CAP in a tertiary referral center from July 2003 to April 2016 were retrospectively examined. Results: There were 13 men and six women, with a mean age of 75.3 +/- 5.6 years (range: 65-86 years). Perforation grade was Ellis type II in five patients (26.3%), and Ellis type III in 14 patients (73.7%). Cardiac tamponade developed in six patients (31.6%), and intra-aortic balloon pumping was needed in four patients (21.1%). The overall success rate for CS implantation rate was 94.7%. The overall in-hospital mortality rate was 15.8%; the in-hospital myocardial infarction rate was 63.2%. Among 16 survival-to-discharge cases, dual antiplatelet therapy (DAPT) was prescribed in 14 cases (87.5%) for a mean duration of 14 months. Overall, there were five angiogram- proven CS failures among 18 patients receiving successful CS implantation. The 1, 2 and 4 years of actuarial freedom from the CS failure were 78%, 65%, and 43% in the angiogram follow-up patients. Conclusions: CS implantation for CAP is feasible and effective in elderly patients, while CS failure remains a major concern that encourages regular angiographic follow-up in these case. PMID- 29167614 TI - Thirty-Day and One-Year Clinical Outcomes of Bioresorbable Vascular Scaffold Implantation: A Single-Center Experience. AB - Background: Available data on the use of the Bioresorbable vascular scaffold (BVS) (Abbott Vascular, Santa Clara, CA) in real-world patients is limited, particularly in Asian populations. The aim of this study was to assess clinical outcomes of patients treated with a BVS in real-world practice in Taiwan. Methods: This study focused on 156 patients with coronary artery disease and a total of 249 lesions who received BVS implantation from October 2012 to October 2015. The study's primary endpoint was major adverse cardiac event (MACE), such as a myocardial infarction (MI), target vessel revascularization (TVR), target lesion revascularization (TLR), definite or possible scaffold thrombosis, cardiovascular death, and all-cause mortality during the thirty-day follow-up period. The secondary endpoint was MACE during the one-year follow-up period. Additionally, the composite clinical secondary endpoint was target lesion failure (TLF), which was called device-oriented composite endpoint. Results: The average age of the patients was 60.34 +/- 10.15 years, and 81.4% were male. The average of Syntax score was 12.42 +/- 8.77 points. 44.2 % lesions were type B2 or C. At 31 days, one patient experienced a MACE (1/156) the composite of two TLF (2/249) with ST elevation MI, which was related to scaffold thrombosis. At one-year, 5.1 % (8/156) of the patients experienced a MACE and 3.6% (9/249) of the lesions experienced a TLF. There was no cardiovascular or all-cause mortality in the 30 day follow-up. The one-year cardiovascular and all-cause mortality rates were each 1.3%, respectively. Diabetes, ostial lesion, bifurcation lesion, and non standard dual anti-platelet therapy (DAPT) were the strong associations of one year TLF. Conclusions: Even with difficult and complex lesions of patients in this study, acceptable outcomes were achieved with low definite or possible scaffold thrombosis rates after BVS implantation. And despite anatomical issues, it is important to complete standard DAPT. PMID- 29167615 TI - Vocal Cord Paralysis and Laryngeal Trauma in Cardiac Surgery. AB - Background: Cardiac surgery - associated iatrogenic laryngeal trauma is often overlooked. We investigated the risk factors of vocal cord paralysis in cardiac surgery. Methods: Medical records were reviewed from 169 patients who underwent elective or emergency cardiac surgeries. Patients had transesophageal echocardiography (TEE) placed either under video fiberscopic image guidance (guided group) or blind placement (blind group). Routine postoperative otolaryngologist consultation with video laryngoscopic recording were performed. Results: Vocal cord paralyses were found in 18 patients (10.7%; left-13, right-4, bilateral-1). The risk of vocal cord paralysis was associated with emergency operation [odds ratio, 97.5 (95% confidence interval [CI], 2.9 to 366), p = 0.01]. Use of fiberscope-guided TEE [odds ratio, 0.04 (95% CI 0.01 to 0.87), p = 0.04] can effectively reduce vocal cord injury. Conclusions: Emergency cardiac surgery increased the risk of vocal cord paralysis. Fiberscope-guided TEE placement is recommended for all patients having cardiac surgery to decrease the risk of severe peri-operative laryngeal trauma. PMID- 29167616 TI - Surgical Acute Volume-Overload Impacts Early on Myocardium - An Experimental Study. AB - Background: Acute volume-overload (AVO) predisposes to cardiac failure. Global cardiac injury may ensue after acute right-sided distension of the heart due to AVO. We experimentally investigated whether surgical AVO impacts early on the myocardium and some markers of injury. Methods: Thirty-four syngeneic Fisher rats underwent surgical abdominal aortocaval fistula to induce AVO. The hearts were procured for regional and quantitative histology after one and three days. Gene expressions for atrial natriuretic peptide (ANP), matrix metalloprotease 9 (MMP9), transforming growth factor beta (TGFbeta) and YKL40 were investigated for myocardial injury. Results: The relative number of ischemic intramyocardial arteries were abundant in the septum of the hearts with AVO compared with controls at day 1 and 3 [0.16 +/- 0.02 vs. 0.02 +/- 0.01, point score unit (PSU), p = 0.002 and 0.14 +/- 0.02 vs. 0.02 +/- 0.01, PSU, p = 0.009, respectively] followed by similar changes in the left ventricle at day 3 (0.11 +/- 0.02 vs. 0.04 +/- 0.01, PSU, p = 0.007). Indicating early myocardial injury, ANP (p = 0.019) was increased in AVO hearts as compared with controls at day 1, as expected. More interestingly, MMP9 (p = 0.003 and p = 0.006), TGFbeta (p = 0.002 and p = 0.004) and YKL40 (p = 0.001 and p = 0.003) expressions were significantly increased at day 1 and 3, along with macrophage infiltration into the myocardium supporting the role of factors produced by alternatively activated macrophages in the pathogenesis of AVO-induced pathophysiology in the heart. Conclusions: Surgical AVO induces an early ischemic myocardial response observed in the intramyocardial arteries. Early expression of key parameters of cardiac remodeling suggest for the onset of early cardiac failure after AVO. PMID- 29167617 TI - Statin Attenuated Myocardial Inflammation Induced by PM2.5 in Rats. AB - Background: Here, the study aims to explore the effect of PM2.5 exposure on atherosclerosis in rats. Materials and Methods: 32 Wistar rats were selected in our study. An atherosclerosis model was established. All rats were evenly divided into four groups, including normal control group (NC), model control group (MC), model PM2.5 group (PM2.5) and model Atorvastatin group (Atorvastatin). The rats in NC and model control group were treated with saline 1 ml/kg body weight by tail intravenous injection, while the rats in PM2.5 group were exposed to PM2.5 suspension. The rats in atorvastatin group were given atorvastatin by gavage with 10 mg.kg-1.per day for 12 weeks until PM2.5 injection. After 24 h, all rats in each group were sacrificed. Pathological analysis, immunohistochemistry (IHC) and electrophoretic mobility shift assays (EMSA) were carried out. Results: PM2.5 exposure significantly reduced the levels of triglyceride (TG), high density lipoprotein (HDL) and superoxide dismutase (SOD), but promoted the levels of total cholesterol (TC), low density lipoprotein (LDL), atherosclerosis index (AI), malondialdehyde (MDA), tumor necrosis factor-alpha (TNF-alpha) and high sensitivity C-reactive protein (hs-CRP) in the rats of PM2.5 group than MC group (p < 0.05). PM2.5 group showed activated nuclear factor-kappa B (NF-kappaB), seriously damaged myocardial coronary branches and the highest nuclear translocation rate. Atorvastatin significantly improved the levels of TG, HDL, SOD, interleukin-6 (IL-6), and reduced the levels of TC, LDL, AI, MDA, TNF-alpha, hs-CRP, oxidized low-density lipoprotein (ox-LDL) and blood pressure, even the nuclear translocation rate. Conclusions: PM2.5 exposure contributes to atherosclerosis in rats, which correlate with the levels of cholesterol, oxidative stress and inflammatory response. Atorvastatin could attenuate myocardial inflammation caused by PM2.5 exposure in rats. PMID- 29167618 TI - Air Pollution Particular Matter and Atherosclerosis. PMID- 29167619 TI - Exenatide Inhibits the KCa3.1 Channels of Aortic Vascular Smooth Muscle in Diabetic Rats. AB - Background: KCa3.1 ion channels play an important role during atherosclerosis. We aimed to investigate the effect of exenatide on KCa3.1 expression in aortic vascular smooth muscle cells (VSMCs) of diabetic rats. Methods: Sprague-Dawley rats were randomly divided into normal control (NC), diabetes model (DM), and exenatide treatment (ET) groups. Hematoxylin and eosin and alpha-actin immunohistochemical staining were used to detect changes in rat aortic vascular smooth muscle. Quantitative RT-PCR and Western blot analysis were used to detect changes in KCa3.1 mRNA and protein levels, respectively. Results: Aortic tissue staining in the DM group revealed an absence of smooth or integrated endothelium, increased smooth muscle cell proliferation in the media, smooth muscle hyperplasia, disorganized smooth muscle cells, and an increased number of collagen fibers, relative to the NC and ET groups. KCa3.1 mRNA expression was higher in the DM group than in the NC and ET groups. Similarly, the KCa3.1 protein level was higher in the DM group than in the NC and ET groups. The KCa3.1 protein level did not significantly differ between the ET and NC groups. Conclusions: Exenatide could inhibit the expression of the KCa3.1 channel in VSMCs of diabetic rats. PMID- 29167620 TI - Obstructive Sleep Apnea Independently Increases the Incidence of Heart Failure and Major Adverse Cardiac Events: A Retrospective Population-Based Follow-Up Study. AB - Background: Obstructive sleep apnea (OSA) is common in heart failure (HF) patients and exacerbates the outcome of this chronic disease. However, the frequency of HF arising from OSA is varied, with little supporting literature. Here, we aimed to clarify the incidence risk of HF and major adverse cardiac events (MACEs) in OSA patients from the Taiwan large database. Methods and Results: From 2000-2010, a total of 2699 newly diagnosed OSA patients after polysomnographic study and 13,490 non-OSA patients utilizing 1:5 matching was enrolled and followed to 2011. Compared to the non-OSA cohort, the OSA cohort increased its MACEs incidence 1.95-fold high and HF incidence reached its highest level, up to 2.75-fold [confidential interval (CI): 1.76-4.29; p value < 0.001]. The most common MACE event was stroke, with a 1.75-fold higher risk in the OSA cohort (CI: 1.37-2.20; p value < 0.001). Although the trend is similar, the OSA cohort showed an increased incidence of atrial fibrillation of approximately 1.63 fold high, (CI: 0.78-3.40; p value: 0.193) and 1.44 high, (CI: 0.74-2.79; p value: 0.287) in myocardial infarction. Between genders, HF risk is considerably higher in female OSA cohort than in corresponding males [female: 6.13 (2.68 14.00), p value < 0.01; male: 1.95 (1.11-3.43), p value = 0.020]. Conclusions: OSA patients have nearly triple the HF incidence risk than the non-OSA population, particularly in female OSA patients. PMID- 29167621 TI - Is a Three-Dimensional Printing Model Better Than a Traditional Cardiac Model for Medical Education? A Pilot Randomized Controlled Study. AB - Background: Three-dimensional (3D) printing is a newly-emerged technology converting a series of two-dimensional images to a touchable 3D model, but no studies have investigated whether or not a 3D printing model is better than a traditional cardiac model for medical education. Methods: A 3D printing cardiac model was generated using multi-slice computed tomography datasets. Thirty-four medical students were randomized to either the 3D Printing Group taught with the aid of a 3D printing cardiac model or the Traditional Model Group with a commonly used plastic cardiac model. Questionnaires with 10 medical questions and 3 evaluative questions were filled in by the students. Results: A 3D printing cardiac model was successfully generated. Students in the 3D Printing Group were slightly quicker to answer all questions when compared with the Traditional Model Group (224.53 +/- 44.13 s vs. 238.71 +/- 68.46 s, p = 0.09), but the total score was not significantly different (6.24 +/- 1.30 vs. 7.18 +/- 1.70, p = 0.12). Neither the students'satisfaction (p = 0.48) nor their understanding of cardiac structures (p = 0.24) was significantly different between two groups. More students in the 3D Printing Group believed that they had understood at least 90% of teaching content (6 vs. 1). Both groups had 12 (70.6%) students who preferred a 3D printing model for medical education. Conclusions: A 3D printing model was not significantly superior to a traditional model in teaching cardiac diseases in our pilot randomized controlled study, yet more studies may be conducted to validate the real effect of 3D printing on medical education.

PMID- 29167623 TI - Bioresorbable Vascular Scaffold Stent Delivered to Tortuous Lesions by Using the "Five-in-Six" System. AB - A 5Fr ST01, which is a straight-tip guiding catheter with an inner lumen of 1.5 mm, is frequently used to perform the "child-in-mother" technique, which is also referred to as the "5-in-6" technique. A 6Fr or larger size guiding catheter can facilitate bioresorbable everolimus-eluting vascular scaffold (BVS) delivery. For tortuous lesions, the 5-in-6 technique can facilitate balloon catheters and the BVS in crossing tortuous lesions by increasing the back-up support. However, this maneuver couldn't be used for the larger size of BVS like 3.5-mm. Besides, it is necessary to preload the BVS into 5Fr ST01 guiding catheter to check whether this could really be done. We present a case in which a 5Fr ST01 catheter and the 5-in 6 technique were successfully used in distal delivery of a BVS to cross a very tortuous right coronary artery lesion.

AB - This article offers a contribution to the history of scientific ideas by proposing an epistemological argument supporting the assumption made by Miller whereby Niels Bohr has been influenced by cubism (Jean Metzinger) when he developed his non-intuitive complementarity principle. More specifically, this essay will identify the Bergsonian duree as the conceptual bridge between Metzinger and Bohr. Beyond this conceptual link between the painter and the physicist, this paper aims to emphasize the key role played by art in the development of human knowledge. PMID- 29167626 TI - Exploring spatial and temporal patterns of visceral leishmaniasis in endemic areas of Bangladesh. AB - Background: Visceral leishmaniasis is a considerable public health burden on the Indian subcontinent. The disease is highly endemic in the north-central part of Bangladesh, affecting the poorest and most marginalized communities. Despite the fact that visceral leishmaniasis (VL) results in mortality, severe morbidity, and socioeconomic stress in the region, the spatiotemporal dynamics of the disease have largely remained unexplored, especially in Bangladesh. Methods: Monthly VL cases between 2010 and 2014, obtained from subdistrict hospitals, were studied in this work. Both global and local spatial autocorrelation techniques were used to identify spatial heterogeneity of the disease. In addition, a spatial scan test was used to identify statistically significant space-time clusters in endemic locations of Bangladesh. Results: Global and local spatial autocorrelation indicated that the distribution of VL was spatially autocorrelated, exhibiting both contiguous and relocation-type of diffusion; however, the former was the main type of VL spread in the study area. The spatial scan test revealed that the disease had ten times higher incidence rate within the clusters than in non cluster zones. Both tests identified clusters in the same geographic areas, despite the differences in their algorithm and cluster detection approach. Conclusion: The cluster maps, generated in this work, can be used by public health officials to prioritize areas for intervention. Additionally, initiatives to control VL can be handled more efficiently when areas of high risk of the disease are known. Because global environmental change is expected to shift the current distribution of vectors to new locations, the results of this work can help to identify potentially exposed populations so that adaptation strategies can be formulated. PMID- 29167627 TI - The importance of human population characteristics in modeling Aedes aegypti distributions and assessing risk of mosquito-borne infectious diseases. AB - Background: The mosquito Aedes aegypti has long been a vector for human illness in the Southeastern United States. In the past, it has been responsible for outbreaks of dengue, chikungunya, and yellow fever and, very recently, the Zika virus that has been introduced to the region. Multiple studies have modeled the geographic distribution of Ae. aegypti as a function of climate factors; however, this ignores the importance of humans to the anthropophilic biter. Furthermore, Ae. aegypti thrives in areas where humans have created standing water sites, such as water storage containers and trash. As models are developed to examine the potential impact of climate change, it becomes increasingly important to include the most comprehensive set of predictors possible. Results: This study uses Maxent, a species distribution model, to evaluate the effects of adding poverty and population density to climate-only models. Performance was evaluated through model fit statistics, such as AUC, omission, and commission, as well as individual variable contributions and response curves. Models which included both population density and poverty exhibited better predictive power and produced more precise distribution maps. Furthermore, the two human population characteristics accounted for much of the model contribution-more so than climate variables. Conclusions: Modeling mosquito distributions without accounting for their dependence on local human populations may miss factors that are very important to niche realization and subsequent risk of infection for humans. Further research is needed to determine if additional human characteristics should be evaluated for model inclusion. PMID- 29167628 TI - A comparative study of job satisfaction among nurses, psychologists/psychotherapists and social workers working in Quebec mental health teams. AB - Background: This study identified multiple socio-professional and team effectiveness variables, based on the Input-Mediator-Output-Input (IMOI) model, and tested their associations with job satisfaction for three categories of mental health professionals (nurses, psychologists/psychotherapists, and social workers). Methods: Job satisfaction was assessed with the Job Satisfaction Survey. Independent variables were classified into four categories: 1) Socio professional Characteristics; 2) Team Attributes; 3) Team Processes; and 4) Team Emergent States. Variables were entered successively, by category, into a hierarchical regression model. Results: Team Processes contributed the greatest number of variables to job satisfaction among all professional groups, including team support which was the only significant variable common to all three types of professionals. Greater involvement in the decision-making process, and lower levels of team conflict (Team Processes) were associated with job satisfaction among nurses and social workers. Lower seniority on team (Socio-professional Characteristics), and team collaboration (Team Processes) were associated with job satisfaction among nurses, as was belief in the advantages of interdisciplinary collaboration (Team Emergent States) among psychologists. Knowledge sharing (Team Processes) and affective commitment to the team (Team Emergent States) were associated with job satisfaction among social workers. Conclusions: Results suggest the need for mental health decision-makers and team managers to offer adequate support to mental health professionals, to involve nurses and social workers in the decision-making process, and implement procedures and mechanisms favourable to the prevention or resolution of team conflict with a view toward increasing job satisfaction among mental health professionals. PMID- 29167629 TI - The Effects of Phacoemulsification and Intraocular Lens Implantation on Anatomical and Functional Parameters in Patients with Primary Angle Closure: A Prospective Study. (An American Ophthalmological Society Thesis). AB - Purpose: To investigate the clinical, anatomical, and patient-reported outcomes of phacoemulsification (PE) with intraocular lens implantation performed to treat primary angle closure (PAC) and primary angle-closure glaucoma (PACG). Methods: Patients were evaluated at baseline and at 6 months after PE. The examination included visual acuity, intraocular pressure (IOP), visual field, optic nerve head, endothelial cell count (ECC), aqueous depth, and ocular biometric parameters. Patient-reported visual function and health status were assessed. Coprimary outcome measures were IOP changes, angle widening, and patient-reported visual function; secondary outcome measures were visual acuity changes, use of IOP-lowering medications, and complications. Univariate and multivariate analyses were performed to determine the predictors of IOP change. Results: Thirty-nine cases were identified, and postoperative data were analyzed for 59 eyes, 39 with PACG and 20 with PAC. Globally, PE resulted in a mean reduction in IOP of -6.33 mm Hg (95% CI, -8.64 to -4.01, P<.001). Aqueous depth and angle measurements improved (P<.01), whereas ECC significantly decreased (P<.001). Both corrected and uncorrected visual acuity improved (P<.01). The EQ visual analog scale did not change (P=.16), but VFQ-25 improved (P<.01). The IOP-lowering effect of PE was greater in the PACG compared to the PAC group (P=.04). In both groups, preoperative IOP was the most significant predictor of IOP change (P<.01). No sight-threatening complications were recorded. Conclusions: Our data support the usefulness of PE in lowering the IOP in patients with PAC and PACG. Although PE resulted in several anatomical and patient-reported visual improvements, we observe that a marked decrease in ECC should be carefully weighed before surgery. PMID- 29167630 TI - Family-Directed Cognitive Adaptation Pilot: Teaching Cognitive Adaptation to Families of Individuals with Schizophrenia. AB - Cognitive deficits are a major determinant of functional outcome in schizophrenia. A promising treatment involves teaching individuals to use cognitive adaptation strategies to minimize the functional impact of cognitive difficulties. We developed Family Directed Cognitive Adaptation (FCA) to train caregivers to help their relatives with schizophrenia use cognitive adaptations to improve living skills. The goal of this open pilot trial was to examine the feasibility of FCA. Ten adults with schizophrenia, each with at least one relative, participated in FCA and were evaluated at baseline, post-treatment, and 6-month follow-up. Domains assessed included adaptive functioning, psychiatric symptoms, school/work involvement, hospitalizations, family burden, and treatment satisfaction. Participants reported high levels of satisfaction with FCA, and all families completed the 16-session intervention. Relatives reported reduced burden at termination and follow-up. No participants were hospitalized during the treatment or follow-up period, and rates of work/school involvement increased from 30% at baseline to 50% at the end of treatment and follow-up. Individuals improved in negative symptoms and adaptive functioning over the course of treatment, but these gains were not maintained. This pilot provides preliminary support for the acceptability and feasibility of FCA, and points to the need to address the maintenance of treatment gains after termination. PMID- 29167632 TI - 2015: an eventful year for the Metabolomics Society. PMID- 29167631 TI - Towards eco-friendly crop protection: natural deep eutectic solvents and defensive secondary metabolites. AB - With mounting concerns over health and environmental effects of pesticides, the search for environmentally acceptable substitutes has amplified. Plant secondary metabolites appear in the horizon as an attractive solution for green crop protection. This paper reviews the need for changes in the techniques and compounds that, until recently, have been the mainstay for dealing with pest insects. Here we describe and discuss main strategies for selecting plant-derived metabolites as candidates for sustainable agriculture. The second part surveys ten important insecticidal compounds, with special emphasis on those involved in human health. Many of these insecticidal metabolites, however, are crystalline solids with limited solubility which might potentially hamper commercial formulation. As such, we introduce the concept of natural deep eutectic solvents for enhancing solubility and stability of such compounds. The concept, principles and examples of green pest control discussed here offer a new suite of environmental-friendly tools designed to promote and adopt sustainable agriculture. PMID- 29167633 TI - Integrating Brain Science and Law: Neuroscientific Evidence and Legal Perspectives on Protecting Individual Liberties. AB - Advances in neuroscientific techniques have found increasingly broader applications, including in legal neuroscience (or "neurolaw"), where experts in the brain sciences are called to testify in the courtroom. But does the incursion of neuroscience into the legal sphere constitute a threat to individual liberties? And what legal protections are there against such threats? In this paper, we outline individual rights as they interact with neuroscientific methods. We then proceed to examine the current uses of neuroscientific evidence, and ultimately determine whether the rights of the individual are endangered by such approaches. Based on our analysis, we conclude that while federal evidence rules constitute a substantial hurdle for the use of neuroscientific evidence, more ethical safeguards are needed to protect against future violations of fundamental rights. Finally, we assert that it will be increasingly imperative for the legal and neuroscientific communities to work together to better define the limits, capabilities, and intended direction of neuroscientific methods applicable for use in law. PMID- 29167635 TI - Physical Exercise Promotes Novel Object Recognition Memory in Spontaneously Hypertensive Rats after Ischemic Stroke by Promoting Neural Plasticity in the Entorhinal Cortex. AB - Cerebral ischemia leads to memory impairment, and several studies have indicated that physical exercise (PE) has memory-improving effects after ischemia. This study was designed to further explore the specific role of PE in novel object recognition (NOR) memory after stroke and the exact cortical regions in which memory is restored by PE. Spontaneously hypertensive rats (SHR) were subjected to transient middle cerebral artery occlusion (tMCAO) or sham surgery, followed by 26 days of PE starting on day 3 post-tMCAO. Thereafter, infarct volume, neurobehavioral outcome and NOR memory were assessed. Immunofluorescence staining and Luxol Fast Blue (LFB) staining were performed in the prefrontal cortex, entorhinal cortex and corpus callosum regions. Western blot analysis was performed to detect expressions of Nestin, Bcl-2 and SYN proteins in the entorhinal cortex. After tMCAO, NOR memory impairment was found in SHR. Rats subjected to PE post-tMCAO showed increased discrimination ratio, as well as significant decreases in infarct volumes and modified neurological severity scores (mNSS), when compared with tMCAO rats without PE. After stroke, NeuN positive cell number was drastically reduced in the entorhinal cortex, rather than in the prefrontal cortex. Ischemic stroke had no impact on myelin and phospholipids, and the ratio of SMI-32/MBP in the corpus callosum. PE increased NeuN, Nestin, Ki67, MBP, SYN, PSD-95 and Bcl-2 expressions in the entorhinal cortex, while TUNEL and SMI-32 expressions were decreased. In conclusion, the NOR memory-improving capacity promoted by PE was closely related to neuronal cell proliferation and synaptic plasticity of the entorhinal cortex. PMID- 29167634 TI - Circular RNAs: A Novel Player in Development and Disease of the Central Nervous System. AB - Circular RNAs (circRNAs) own unique capabilities to communicate with nucleic acids and ribonucleoproteins and are emerging as indispensable compositions of the regulatory messages encoded in the genome. Due to lack of 3' termini, circRNAs are more resistant to degradation by exonuclease RNase R and possess greater stability than linear RNAs. Moreover, circRNAs can act as microRNA (miRNA) sponge and affect messenger RNA (mRNA) splicing and transcription. By virtue of their great stability and elaborate regulatory mechanisms of gene expression, circRNAs play important roles in certain physiological activities. The development, homeostasis and stress response of the central nervous system (CNS) depend upon precise temporal and spatial regulation of gene networks. Moreover, emerging evidence has revealed that circRNAs are spatiotemporally regulated and dynamically expressed during brain development; therefore, they can exert significant influences on CNS development and diseases. In this review, we highlight the biogenesis of circRNAs and their central roles in regulation of CNS development and diseases. PMID- 29167636 TI - Preventive Strength of Dyadic Social Interaction against Reacquisition/Reexpression of Cocaine Conditioned Place Preference. AB - The reorientation away from drugs of abuse and toward social interaction is a highly desirable but as yet elusive goal in the therapy of substance dependence. We could previously show that cocaine preferring Sprague-Dawley rats which engaged in only four 15 min episodes of dyadic social interaction (DSI) did not reacquire and reexpress cocaine conditioned place preference (CPP) after a single cocaine exposure. In the present study, we investigated how strong this preventive effect of DSI is. In corroboration of our previous findings in rats, four 15 min DSI episodes prevented the reacquisition/reexpression of cocaine CPP in mice. However, this effect was only observed if only one cocaine conditioning session (15 min) was used. If mice were counterconditioned with a total of four cocaine sessions, the cocaine CPP reemerged. Interestingly, the opposite also held true: in mice that had acquired/expressed cocaine CPP, one conditioning session with DSI did not prevent the persistence of cocaine CPP, whereas four DSI conditioning sessions reversed CPP for 15 mg/kg intraperitoneal cocaine. Of note, this cocaine dose was a strong reward in C57BL/6J mice, causing CPP in all tested animals. Our findings suggest that both the reversal (reconditioning) of CPP from cocaine to DSI as well as that from DSI to cocaine requires four conditioning sessions. As previously shown in C57BL/6 mice from the NIH substrain, mice from the Jackson substrain also showed a greater relative preference for 15 mg/kg intraperitoneal cocaine over DSI, whereas Sprague-Dawley rats were equally attracted to contextual stimuli associated with this cocaine dose and DSI. Also in corroboration of previous findings, both C57BL/6J mice and experimenters several generations removed from the original ones produced CPP for DSI to a lesser degree than Sprague-Dawley rats. Our findings demonstrate the robustness of our experimental model across several subject- and experimenter generations in two rodent genus (i.e., mouse and rat) and allow the quantification of the strength (i.e., persistence) of the preventive effect of DSI against the reacquisition/reexpression of cocaine CPP, arguably a model for cocaine relapse. PMID- 29167637 TI - Variations in Static Force Control and Motor Unit Behavior with Error Amplification Feedback in the Elderly. AB - Error amplification (EA) feedback is a promising approach to advance visuomotor skill. As error detection and visuomotor processing at short time scales decline with age, this study examined whether older adults could benefit from EA feedback that included higher-frequency information to guide a force-tracking task. Fourteen young and 14 older adults performed low-level static isometric force tracking with visual guidance of typical visual feedback and EA feedback containing augmented high-frequency errors. Stabilogram diffusion analysis was used to characterize force fluctuation dynamics. Also, the discharge behaviors of motor units and pooled motor unit coherence were assessed following the decomposition of multi-channel surface electromyography (EMG). EA produced different behavioral and neurophysiological impacts on young and older adults. Older adults exhibited inferior task accuracy with EA feedback than with typical visual feedback, but not young adults. Although stabilogram diffusion analysis revealed that EA led to a significant decrease in critical time points for both groups, EA potentiated the critical point of force fluctuations [Formula: see text], short-term effective diffusion coefficients (Ds), and short-term exponent scaling only for the older adults. Moreover, in older adults, EA added to the size of discharge variability of motor units and discharge regularity of cumulative discharge rate, but suppressed the pooled motor unit coherence in the 13-35 Hz band. Virtual EA alters the strategic balance between open-loop and closed-loop controls for force-tracking. Contrary to expectations, the prevailing use of closed-loop control with EA that contained high-frequency error information enhanced the motor unit discharge variability and undermined the force steadiness in the older group, concerning declines in physiological complexity in the neurobehavioral system and the common drive to the motoneuronal pool against force destabilization. PMID- 29167638 TI - Hyper-Transcranial Alternating Current Stimulation: Experimental Manipulation of Inter-Brain Synchrony. AB - We walk together, we watch together, we win together: Interpersonally coordinated actions are omnipresent in everyday life, yet the associated neural mechanisms are not well understood. Available evidence suggests that the synchronization of oscillatory activity across brains may provide a mechanism for the temporal alignment of actions between two or more individuals. In an attempt to provide a direct test of this hypothesis, we applied transcranial alternating current stimulation simultaneously to two individuals (hyper-tACS) who were asked to drum in synchrony at a set pace. Thirty-eight female-female dyads performed the dyadic drumming in the course of 3 weeks under three different hyper-tACS stimulation conditions: same-phase-same-frequency; different-phase-different-frequency; sham. Based on available evidence and theoretical considerations, stimulation was applied over right frontal and parietal sites in the theta frequency range. We predicted that same-phase-same-frequency stimulation would improve interpersonal action coordination, expressed as the degree of synchrony in dyadic drumming, relative to the other two conditions. Contrary to expectations, both the same phase-same-frequency and the different-phase-different-frequency conditions were associated with greater dyadic drumming asynchrony relative to the sham condition. No influence of hyper-tACS on behavioral performance was seen when participants were asked to drum separately in synchrony to a metronome. Individual and dyad preferred drumming tempo was also unaffected by hyper-tACS. We discuss limitations of the present version of the hyper-tACS paradigm, and suggest avenues for future research.

AB - Alzheimer's disease (AD) and its prodromal state amnestic mild cognitive impairment (aMCI) are characterized by widespread abnormalities in inter-areal white matter fiber pathways and parallel disruption of default mode network (DMN) resting state functional and effective connectivity. In healthy subjects, DMN and task positive network interaction are modulated by the thalamus suggesting that abnormal task-based DMN deactivation in aMCI may be a consequence of impaired thalamo-cortical white matter circuitry. Thus, this article uses a multimodal approach to assess white matter integrity between thalamus and DMN components and associated effective connectivity in healthy controls (HCs) relative to aMCI patients. Twenty-six HC and 20 older adults with aMCI underwent structural, functional and diffusion MRI scanning using the high angular resolution diffusion weighted acquisition protocol. The DMN of each subject was identified using independent component analysis (ICA) and resting state effective connectivity was calculated between thalamus and DMN nodes. White matter integrity changes between thalamus and DMN were investigated with constrained spherical deconvolution (CSD) tractography. Significant structural deficits in thalamic white matter projection fibers to posterior DMN components posterior cingulate cortex (PCC) and lateral inferior parietal lobe (IPL) were identified together with significantly reduced effective connectivity from left thalamus to left IPL. Crucially, impaired thalamo-cortical white matter circuitry correlated with memory performance. Disrupted thalamo-cortical structure was accompanied by significant reductions in IPL and PCC cortico-cortical effective connectivity. No structural deficits were found between DMN nodes. Abnormal posterior DMN activity may be driven by changes in thalamic white matter connectivity; a view supported by the close anatomical and functional association of thalamic nuclei effected by AD pathology and the posterior DMN nodes. We conclude that dysfunctional posterior DMN activity in aMCI is consistent with disrupted cortico-thalamo-cortical processing and thalamic-based dissemination of hippocampal disease agents to cortical hubs.

AB - Medication with neuroleptics has been associated with adipose tissue dysfunctions and, in particular, with increased visceral fat amount. However, several studies suggested that antipsychotic treatment might not be the main responsible of fat mass accumulation, as this has been also described in not treated psychotic patients. One of the most used "drug-free" rodent models of psychosis is the social isolation rearing of young adult rats, which provides a non-pharmacologic method of inducing long-term alterations reminiscent of symptoms seen in psychotic patients. Recent data highlighted a crucial role of redox imbalance in adipose tissue dysfunctions, in terms of decreased antioxidant defense and increased reactive oxygen species (ROS). Here, we investigated possible oxidative stress-related biomolecular alterations associated with visceral fat increase in 7 week isolated rats. To this purpose, we quantified total and visceral fat amount by using dual-energy X-ray (DEXA) absorptiometry. On visceral fat, we analyzed the expression of specific ROS-producer genes (Nox1, Nox4, Hmox-1), antioxidant enzymes (Prdx1 and Ucp-1) and oxidative stress-induced damage markers (Cidea, Slc2a4, and Acacb). The impact of oxidative stress on beta3-adrenergic receptors (Adrb3), at both mRNA and protein level, was also assessed. We found that 7 weeks of social isolation induced an increase in total and visceral fat, associated with a decrease in Prdx1 (mRNA and protein) as well as Ucp-1 mRNA levels and an enhanced expression of Nox1 (mRNA and protein) and Hmox-1 mRNA. No differences were detected in Nox4 mRNA levels between grouped and isolated animals. Elevations in Cidea, Slc2a4, and Acacb expression in visceral fat of isolated animals accounted for oxidative stress-related damage in this tissue, further associated with a significant increase in Adrb3 mRNA and protein. Our results provide a novel understanding of the pathological link existing among psychosocial stress-induced psychosis, adipose tissue dysfunctions and redox imbalance, opening new therapeutic perspectives for the treatment of alterations in peripheral tissues associated with this mental disorder. PMID- 29167641 TI - alpha7 Nicotinic Agonist AR-R17779 Protects Mice against 2,4,6-Trinitrobenzene Sulfonic Acid-Induced Colitis in a Spleen-Dependent Way. AB - The existence of a cholinergic anti-inflammatory pathway negatively modulating the inflammatory and immune responses in various clinical conditions and experimental models has long been postulated. In particular, the protective involvement of the vagus nerve and of nicotinic Ach receptors (nAChRs) has been proposed in intestinal inflammation and repeatedly investigated in DSS- and TNBS induced colitis. However, the role of alpha7 nAChRs stimulation is still controversial and the potential contribution of alpha4beta2 nAChRs has never been explored in this experimental condition. Our aims were therefore to pharmacologically investigate the role played by both alpha7 and alpha4beta2 nAChRs in the modulation of the local and systemic inflammatory responses activated in TNBS-induced colitis in mice and to assess the involvement of the spleen in nicotinic responses. To this end, TNBS-exposed mice were sub-acutely treated with various subcutaneous doses of highly selective agonists (AR-R17779 and TC-2403) and antagonists (methyllycaconitine and dihydro-beta-erythroidine) of alpha7 and alpha4beta2 nAChRs, respectively, or with sulfasalazine 50 mg/kg per os and clinical and inflammatory responses were evaluated by means of biochemical, histological and flow cytometry assays. alpha4beta2 ligands evoked weak and contradictory effects, while alpha7 nAChR agonist AR-R17779 emerged as the most beneficial treatment, able to attenuate several local markers of colitis severity and to revert the rise in splenic T-cells and in colonic inflammatory cytokines levels induced by haptenization. After splenectomy, AR-R17779 lost its protective effects, demonstrating for the first time that, in TNBS-model of experimental colitis, the anti-inflammatory effect of exogenous alpha7 nAChR stimulation is strictly spleen-dependent. Our findings showed that the selective alpha7 nAChRs agonist AR-R17779 exerted beneficial effects in a model of intestinal inflammation characterized by activation of the adaptive immune system and that the spleen is essential to mediate this cholinergic protection. PMID- 29167642 TI - An Update on AMPK in Hydrogen Sulfide Pharmacology. AB - Hydrogen sulfide (H2S), the third bio-active gasotransmitter, is produced endogenously and tightly involved in the pathogenesis and treatment for various diseases. Adenosine 5'-monophosphate-activated protein kinase (AMPK) plays a paramount role in maintaining cellular energetic balance. Increasing evidences have also suggested AMPK as a novel modulator in multiple pathological conditions. In this paper, we will review the biological principles of H2S and AMPK, and most importantly, the recent discoveries regarding AMPK-mediated pharmacological actions of H2S. Emphasis will be laid on AMPK/H2S interactions in the cardiovascular system, autophagy, diabetic complications, and inflammation. In most cases described in this article, by promoting AMPK activation, H2S exerts cytoprotective effects or therapeutic potentials, though there remain some controversies before we can fully understand the involved mechanisms. Further researches are in need to investigate more closely any relationship between H2S and AMPK, and to put forward the development of H2S donors for clinical application. PMID- 29167643 TI - Post-inflammatory Ileitis Induces Non-neuronal Purinergic Signaling Adjustments of Cholinergic Neurotransmission in the Myenteric Plexus. AB - Uncoupling between ATP overflow and extracellular adenosine formation changes purinergic signaling in post-inflammatory ileitis. Adenosine neuromodulation deficits were ascribed to feed-forward inhibition of ecto-5'-nucleotidase/CD73 by high extracellular adenine nucleotides in the inflamed ileum. Here, we hypothesized that inflammation-induced changes in cellular density may also account to unbalance the release of purines and their influence on [3H]acetylcholine release from longitudinal muscle-myenteric plexus preparations of the ileum of 2,4,6-trinitrobenzenesulfonic acid (TNBS)-treated rats. The population of S100beta-positive glial cells increase, whereas Ano-1-positive interstitial cells of Cajal (ICCs) diminished, in the ileum 7-days after the inflammatory insult. In the absence of changes in the density of VAChT-positive cholinergic nerves detected by immunofluorescence confocal microscopy, the inflamed myenteric plexus released smaller amounts of [3H]acetylcholine which also became less sensitive to neuronal blockade by tetrodotoxin (1 MUM). Instead, [3H]acetylcholine release was attenuated by sodium fluoroacetate (5 mM), carbenoxolone (10 MUM) and A438079 (3 MUM), which prevent activation of glial cells, pannexin-1 hemichannels and P2X7 receptors, respectively. Sodium fluoroacetate also decreased ATP overflow without significantly affecting the extracellular adenosine levels, thus indicating that surplus ATP release parallels reactive gliosis in post-inflammatory ileitis. Conversely, loss of ICCs may explain the lower amounts of adenosine detected in TNBS-treated preparations, since blockade of Cav3 (T-type) channels existing in ICCs with mibefradil (3 MUM) or inhibition of the equilibrative nucleoside transporter 1 with dipyridamole (0.5 MUM), both decreased extracellular adenosine. Data indicate that post inflammatory ileitis operates a shift on purinergic neuromodulation reflecting the upregulation of ATP-releasing enteric glial cells and the depletion of ICCs accounting for decreased adenosine overflow via equilibrative nucleoside transporters. PMID- 29167644 TI - LSD Increases Primary Process Thinking via Serotonin 2A Receptor Activation. AB - Rationale: Stimulation of serotonin 2A (5-HT2A) receptors by lysergic acid diethylamide (LSD) and related compounds such as psilocybin has previously been shown to increase primary process thinking - an ontologically and evolutionary early, implicit, associative, and automatic mode of thinking which is typically occurring during altered states of consciousness such as dreaming. However, it is still largely unknown whether LSD induces primary process thinking under placebo controlled, standardized experimental conditions and whether these effects are related to subjective experience and 5-HT2A receptor activation. Therefore, this study aimed to test the hypotheses that LSD increases primary process thinking and that primary process thinking depends on 5-HT2A receptor activation and is related to subjective drug effects. Methods: Twenty-five healthy subjects performed an audio-recorded mental imagery task 7 h after drug administration during three drug conditions: placebo, LSD (100 mcg orally) and LSD together with the 5-HT2A receptor antagonist ketanserin (40 mg orally). The main outcome variable in this study was primary index (PI), a formal measure of primary process thinking in the imagery reports. State of consciousness was evaluated using the Altered State of Consciousness (5D-ASC) rating scale. Results: LSD, compared with placebo, significantly increased primary index (p < 0.001, Bonferroni-corrected). The LSD-induced increase in primary index was positively correlated with LSD-induced disembodiment (p < 0.05, Bonferroni-corrected), and blissful state (p < 0.05, Bonferroni-corrected) on the 5D-ASC. Both LSD-induced increases in primary index and changes in state of consciousness were fully blocked by ketanserin. Conclusion: LSD induces primary process thinking via activation of 5-HT2A receptors and in relation to disembodiment and blissful state. Primary process thinking appears to crucially organize inner experiences during both dreams and psychedelic states of consciousness. PMID- 29167645 TI - Improving Cardiometabolic Health with Diet, Physical Activity, and Breaking Up Sitting: What about Sleep? AB - Cardiometabolic disease poses a serious health and economic burden worldwide and its prevalence is predicted to increase. Prolonged sitting, lack of physical activity, poor diet, and short sleep duration are ubiquitous behaviors in modern society, and all are independent risk factors in the development of cardiometabolic disease. Existing evidence demonstrates that breaking up prolonged periods of sitting is beneficial for cardiometabolic health, however, studies have not controlled for prior sleep duration. This article examines how prolonged sitting and short sleep duration independently contribute to cardiometabolic risk, and how breaking up sitting and obtaining adequate sleep may reduce this risk. We suggest that as prolonged sitting and short sleep duration influence the same cardiometabolic parameters, there is potential for short sleep to attenuate the positive impact of breaking up prolonged sitting with physical activity. Likewise, breaking up prolonged sitting and obtaining adequate sleep together could improve predictors of cardiometabolic disease, i.e., the combined effect may be stronger than either alone. To explore these perspectives, we propose a research agenda to investigate the relationship between breaking up prolonged sitting with physical activity and short sleep duration. This will provide an evidence-base for informing the design of interventions to reduce the burden of cardiometabolic disease on communities worldwide.

AB - Background: Paired associative stimulation (PAS) is the repeated combination of a sensory stimulus with transcranial magnetic stimulation (TMS) in close temporal association. Recently, a study demonstrated that PAS of an auditory stimulus together with TMS of the temporal cortex is capable of changing the amplitude of auditory evoked potentials (AEP). Objective: This study examined the influence of tone duration and habituation in temporal cortex PAS as elicited by 40 and 20 Hz amplitude modulated auditory steady-state responses (aSSR). Methods: Eighteen subjects participated in two experiments, including two PAS protocols each, which consisted of 200 auditory stimuli (4 kHz) paired with temporal cortex TMS with an interstimulus interval (ISI) of 45 ms between tone onset and TMS pulse, delivered at 0.1 Hz. Experiment 1 compared auditory stimuli with different lengths [PAS (23 ms) vs. PAS (400 ms)]. Experiment 2 investigated verum vs. sham PAS. aSSR for the paired tone (4 kHz) and a control tone (1 kHz) were measured pre- and post interventional-using 40 Hz aSSR in experiment 1 and both 20 and 40 Hz aSSR in experiment 2. Results: A statistically significant, sham-controlled decrease in amplitude was observed for the 20 Hz aSSR using the 4 kHz PAS carrier frequency in experiment 2. Conclusion: Frequency-specific effects for the 20 Hz aSSR confirm the feasibility of auditory PAS and highlight the secondary auditory cortex as its target site, introducing new possible treatment protocols for patients suffering from tinnitus. The amplitude decrease can be explained by principles of spike timing-dependent plasticity and the superposition model of aSSR. PMID- 29167649 TI - The Effect of EMDR and CBT on Low Self-esteem in a General Psychiatric Population: A Randomized Controlled Trial. AB - Although low self-esteem has been found to be an important factor in the development and maintenance of psychopathology, surprisingly little is known about its treatment. This study investigated the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) therapy and Cognitive Behavioural Therapy (CBT), regarding their capacities in enhancing self-esteem in a general psychiatric secondary health care population. A randomized controlled trial with two parallel groups was used. Participants were randomly allocated to either 10 weekly sessions of EMDR (n = 15) or CBT (n = 15). They were assessed pre treatment, after each session, post treatment and at 3 months follow-up on self esteem (Rosenberg Self-esteem Scale and Credibility of Core Beliefs), psychological symptoms (Brief Symptom Inventory), social anxiety, and social interaction (Inventory of Interpersonal Situations) (IIS). The data were analyzed using repeated measures ANOVA for the complete cases (n = 19) and intention-to treat (n = 30) to examine differences over time and between conditions. Both groups, EMDR as well as CBT, showed significant improvements on self-esteem, increasing two standard deviations on the main parameter (RSES). Furthermore, the results showed significant reductions in general psychiatric symptoms. The effects were maintained at 3 months follow-up. No between-group differences could be detected. Although the small sample requires to exercise caution in the interpretation of the findings, the results suggest that, when offering an adequate number of sessions, both EMDR and CBT have the potential to be effective treatments for patients with low self-esteem and a wide range of comorbid psychiatric conditions.

AB - Palmitic acid (PA) has been for long time negatively depicted for its putative detrimental health effects, shadowing its multiple crucial physiological activities. PA is the most common saturated fatty acid accounting for 20-30% of total fatty acids in the human body and can be provided in the diet or synthesized endogenously via de novo lipogenesis (DNL). PA tissue content seems to be controlled around a well-defined concentration, and changes in its intake do not influence significantly its tissue concentration because the exogenous source is counterbalanced by PA endogenous biosynthesis. Particular physiopathological conditions and nutritional factors may strongly induce DNL, resulting in increased tissue content of PA and disrupted homeostatic control of its tissue concentration. The tight homeostatic control of PA tissue concentration is likely related to its fundamental physiological role to guarantee membrane physical properties but also to consent protein palmitoylation, palmitoylethanolamide (PEA) biosynthesis, and in the lung an efficient surfactant activity. In order to maintain membrane phospholipids (PL) balance may be crucial an optimal intake of PA in a certain ratio with unsaturated fatty acids, especially PUFAs of both n-6 and n-3 families. However, in presence of other factors such as positive energy balance, excessive intake of carbohydrates (in particular mono and disaccharides), and a sedentary lifestyle, the mechanisms to maintain a steady state of PA concentration may be disrupted leading to an over accumulation of tissue PA resulting in dyslipidemia, hyperglycemia, increased ectopic fat accumulation and increased inflammatory tone via toll-like receptor 4. It is therefore likely that the controversial data on the association of dietary PA with detrimental health effects, may be related to an excessive imbalance of dietary PA/PUFA ratio which, in certain physiopathological conditions, and in presence of an enhanced DNL, may further accelerate these deleterious effects. PMID- 29167650 TI - Social and Emotional Learning and Academic Achievement in Portuguese Schools: A Bibliometric Study. AB - Social and Emotional Learning (SEL) is an educational movement that is gaining ground throughout the world. We can define SEL as the capacity to recognize and manage emotions, solve problems effectively, and establish positive relationships with others. Research has demonstrated the significant role of SEL in promoting healthy student development and academic achievement. Extensive research confirms that SEL competencies: can be taught, that they promote positive development and reduce problem behaviors, and that they improve students' academic achievement and citizenship. At the international level, several rigorous studies have identified programs and practices that promote SEL. In Portugal, however, no review has yet been published regarding the implementation of SEL programs. Such a study would elucidate the current panorama of SEL programs in Portugal. This study aims to identify research on SEL programs implemented in Portuguese schools and the relationship of those programs with academic achievement. To this end, we have consulted the following databases: Scientific Repository of Open Access of Portugal (RCAAP), Online Knowledge Library (b-on), and Web of Science (WoS). The criteria were: (a) all time frames; (b) publications in either Portuguese or English; (c) programs that developed socio-emotional competencies in Portuguese schools; (d) academic levels including elementary, middle, and high school and (e) students of regular education. Few publications on SEL programs implemented in Portugal were found, although the recent decade has witnessed an upsurge of interest in the topic, principally that arising from academic research. PMID- 29167651 TI - Nonsuicidal Self-injury: A Systematic Review. AB - Objective: Nonsuicidal self-injury (NSSI) refers to the intentional self inflicted destruction of body tissue without suicidal intention and for purposes not socially sanctioned. Our paper presents an up-to-date overview on nonsuicidal, self-injurious behaviors. Method: In accordance with PRISMA guidelines, a systematic literature search was conducted across two databases, PubMed and PsycARTICLES, regarding the main features of NSSI with a focus on epidemiological and etiologic data, diagnostic criteria, and functions. All English articles, published between 1998 and 2016, were considered, and screened against a priori inclusion/exclusion criteria. The search terms include: self harm, self-injury, NSSI, epidemiology, comorbidity, gender, functions and DSM. We also examined the references of the retrieved articles. Results: NSSI is most common among adolescents and young adults, and the age of onset is reported to occur between 12 and 14 years. Comorbidity with borderline personality disorder (BPD) and eating disorders is often reported. DSM-5 includes NSSI as a condition requiring further study. This review gives an overview of the prevalence rates (7.5-46.5% adolescents, 38.9% university students, 4-23% adults) and main causes that appear to stem from childhood trauma, comorbidity with many other disorders and several functions of NSSI, and the potential independence of a NSSI disorder. Conclusion: Over the years, interest in NSSI grew to such an extent that an ongoing debate was instigated on whether NSSI should be considered as a diagnosis in its own right and given its own category. This paper provides an up-to-date overview on self-injury, what is known about it and what remains to be done. Clearly, our understanding of the main issues of NSSI has increased in last two decades. However, future researches is needed to examine the developmental trajectories, cultural backgrounds and shed light on the risk factors and functions as well as clarify its role as an independent diagnostic entity. PMID- 29167652 TI - Eye Contact and Fear of Being Laughed at in a Gaze Discrimination Task. AB - Current approaches conceptualize gelotophobia as a personality trait characterized by a disproportionate fear of being laughed at by others. Consistently with this perspective, gelotophobes are also described as neurotic and introverted and as having a paranoid tendency to anticipate derision and mockery situations. Although research on gelotophobia has significantly progressed over the past two decades, no evidence exists concerning the potential effects of gelotophobia in reaction to eye contact. Previous research has pointed to difficulties in discriminating gaze direction as the basis of possible misinterpretations of others' intentions or mental states. The aim of the present research was to examine whether gelotophobia predisposition modulates the effects of eye contact (i.e., gaze discrimination) when processing faces portraying several emotional expressions. In two different experiments, participants performed an experimental gaze discrimination task in which they responded, as quickly and accurately as possible, to the eyes' directions on faces displaying either a happy, angry, fear, neutral, or sad emotional expression. In particular, we expected trait-gelotophobia to modulate the eye contact effect, showing specific group differences in the happiness condition. The results of Study 1 (N = 40) indicated that gelotophobes made more errors than non-gelotophobes did in the gaze discrimination task. In contrast to our initial hypothesis, the happiness expression did not have any special role in the observed differences between individuals with high vs. low trait-gelotophobia. In Study 2 (N = 40), we replicated the pattern of data concerning gaze discrimination ability, even after controlling for individuals' scores on social anxiety. Furthermore, in our second experiment, we found that gelotophobes did not exhibit any problem with identifying others' emotions, or a general incorrect attribution of affective features, such as valence, intensity, or arousal. Therefore, this bias in processing gaze might be related to the global processes of social cognition. Further research is needed to explore how eye contact relates to the fear of being laughed at. PMID- 29167653 TI - What Drives Them to Drive?-Parents' Reasons for Choosing the Car to Take Their Children to School. AB - Children's school journeys have changed vastly during recent decades: More children are being driven to school in private cars instead of walking and cycling, with many who are entitled to a free school bus service still being driven. Earlier research into travel mode choice has often investigated how urban form impacts upon mode choice regarding school journeys-in particular how urban form hinders or enables the use of the active mode. This paper quantitatively explores parents' stated reasons for choosing the car and the relationship between these reasons and the decision to use the car to take their children to school. We additionally investigate the relationship between sociodemographic factors, distance, and both the stated reasons and the actual mode decision. A sample of 245 parents (194 women) of school children aged 10-15 in the County of Varmland in Sweden were included in the study. The results of PLS-SEM show that the factor Social convenience has a direct relationship with the frequency of car use indicating that the wish to accompany the child and the convenience of car impacts on car choice. If the child is not allowed to travel independently, the parents choose the car to take him/her to school. Sociodemographic factors had a direct relationship with the stated reasons, whereby parents with a higher level of education valued safety/security less. Quite surprisingly, distance (i.e., environmental factor) did not affect car use, indicating that parents drive their children to school regardless of distance. By isolating the particular reasons for choosing the car, this paper focuses on a potentially important missing piece as regards finding out what motivates the increasing car usage in children's school journeys. An increased knowledge of what motivates the decision to take children by car is important for effective policies aimed at changing parents' inclination toward choosing the car. PMID- 29167654 TI - Dark Triad, Perceptions of Organizational Politics and Counterproductive Work Behaviors: The Moderating Effect of Political Skills. AB - The aim of this work focuses on the relationship among the Dark Triad (psychopathy, narcissism, and Machiavellianism), perceptions of organizational politics, political skills, and counterproductive work behavior. This study empirically tests the mediating role of perceptions of organizational politics in the relationship between the Dark Triad and counterproductive work behavior. Furthermore, the study investigates the moderating role of political skills in strengthening the link between the Dark Triad and the perceptions of organizational politics. A sample of 149 participants was randomly selected. To analyze the data of the present work, we employed a structural equation model using partial least square and PROCESS. From empirical findings, we imply an inference that perception of organizational politics partially mediates the Dark Triad's influence on the counterproductive work behavior. Moreover, the results identify the moderating role of political skills in strengthening the link between the Dark Triad and the perceptions of organizational politics. Empirical findings suggest important policy implications for the hospitality industry.

AB - Motion-intent-based finger gesture recognition systems are crucial for many applications such as prosthesis control, sign language recognition, wearable rehabilitation system, and human-computer interaction. In this article, a motion intent-based finger gesture recognition system is designed to correctly identify the tapping of every finger for the first time. Two auto-event annotation algorithms are firstly applied and evaluated for detecting the finger tapping frame. Based on the truncated signals, the Wavelet packet transform (WPT) coefficients are calculated and compressed as the features, followed by a feature selection method that is able to improve the performance by optimizing the feature set. Finally, three popular classifiers including naive Bayes (NBC), K nearest neighbor (KNN), and support vector machine (SVM) are applied and evaluated. The recognition accuracy can be achieved up to 94%. The design and the architecture of the system are presented with full system characterization results. PMID- 29167657 TI - Choices Regarding Thrombolysis Are Modified by the Way to Transfer the Messages. AB - Although thrombolysis is the most effective medical treatment for acute ischemic stroke, many stroke patients eligible for thrombolysis miss this treatment as a result of delay or refusal by the patients and/or their proxies. To explore the influences of prognostic information for different intervals from stroke onset to the start of thrombolytic treatment (OTT) and other factors on the preferences of patients/proxies regarding thrombolytic therapy, a cross-sectional, discrete choice experiment was performed between August 2013 and September 2014. A total of 613 Chinese inpatients or their immediate family members were consecutively recruited at the Department of Neurology. After random assignment to a negative framing group or a positive-framing group, the subjects completed a series of surveys, including nine items about thrombolysis. Latent class analysis (LCA) was used to examine participants' preference paradigms for thrombolysis and to categorize the participants into different subgroups. Subsequently, regression analyses were conducted to explore predictors of categorization of the participants into each subgroup and to construct a thrombolytic decision-making model. LCA revealed an optimal 3-subgroup model including a consent to thrombolysis subgroup and objection to thrombolysis subgroups 1 and 2. Multiple regression analysis demonstrated that compared with assignment to the consent to thrombolysis subgroup, assignment to objection to thrombolysis subgroup 1 or 2 could be predicted by different factors. chi2 tests indicated effects of framing and other factors on participants' choices regarding thrombolysis. Choices regarding thrombolysis were modified by not only prognostic information for different OTT intervals but also message framing, presentation format, and sociodemographic characteristics. To facilitate consent to thrombolysis, physicians should convey prognostic information to patients/proxies on the basis of patient OTT interval and should order the presentation of therapies according to the classification of patients/proxies. Individualized decision-making (IDM) might be an optimal strategy to increase the selection of thrombolysis, which providing important reference points for IDM in other clinical domains. PMID- 29167656 TI - Multivariate Analyses of Balance Test Performance, Vestibular Thresholds, and Age. AB - We previously published vestibular perceptual thresholds and performance in the Modified Romberg Test of Standing Balance in 105 healthy humans ranging from ages 18 to 80 (1). Self-motion thresholds in the dark included roll tilt about an earth-horizontal axis at 0.2 and 1 Hz, yaw rotation about an earth-vertical axis at 1 Hz, y-translation (interaural/lateral) at 1 Hz, and z-translation (vertical) at 1 Hz. In this study, we focus on multiple variable analyses not reported in the earlier study. Specifically, we investigate correlations (1) among the five thresholds measured and (2) between thresholds, age, and the chance of failing condition 4 of the balance test, which increases vestibular reliance by having subjects stand on foam with eyes closed. We found moderate correlations (0.30 0.51) between vestibular thresholds for different motions, both before and after using our published aging regression to remove age effects. We found that lower or higher thresholds across all threshold measures are an individual trait that account for about 60% of the variation in the population. This can be further distributed into two components with about 20% of the variation explained by aging and 40% of variation explained by a single principal component that includes similar contributions from all threshold measures. When only roll tilt 0.2 Hz thresholds and age were analyzed together, we found that the chance of failing condition 4 depends significantly on both (p = 0.006 and p = 0.013, respectively). An analysis incorporating more variables found that the chance of failing condition 4 depended significantly only on roll tilt 0.2 Hz thresholds (p = 0.046) and not age (p = 0.10), sex nor any of the other four threshold measures, suggesting that some of the age effect might be captured by the fact that vestibular thresholds increase with age. For example, at 60 years of age, the chance of failing is roughly 5% for the lowest roll tilt thresholds in our population, but this increases to 80% for the highest roll tilt thresholds. These findings demonstrate the importance of roll tilt vestibular cues for balance, even in individuals reporting no vestibular symptoms and with no evidence of vestibular dysfunction. PMID- 29167658 TI - Atypical Electrophysiological Findings in a Patient with Acute Motor and Sensory Axonal Neuropathy. AB - Guillain-Barre syndrome (GBS) is an immune-mediated polyradiculoneuropathy with acute onset and rapid clinical worsening; early diagnosis and immunomodulating therapy can ameliorate the course of disease. During the first days, however, nerve conduction studies (NCSs) are not always conclusive. Here, we describe a 73 year-old man presenting with progressive muscular weakness of the lower limbs, ascending to the upper limbs, accompanied by distal sensory disturbances. Neuroimaging of brain and spine and NCSs were unremarkable; cerebrospinal fluid analysis revealed no albuminocytologic dissociation. Based on typical clinical features, and on positivity for serum GD1b-IgM antibodies, GBS with proximal conduction failure at multiple radicular levels was postulated, and a standard regime of intravenous immunoglobulin was administered. Four weeks later, the patient presented with flaccid tetraparesis, areflexia, and reduction of position sense, tingling paresthesias, and initial respiratory distress. Repeat NCS still revealed almost normal findings, except for the disappearance of right ulnar nerve F-waves. A few days thereafter, the patient developed severe respiratory insufficiency requiring mechanical ventilation for 2 weeks. On day 50, NCS revealed for the first time markedly reduced compound muscle action potentials and sensory nerve action potentials in all tested nerves, without signs of demyelination; needle electromyography documented widespread denervation. The diagnosis of acute motor and sensory axonal neuropathy was made. After 3 months of intensive rehabilitation, the patient regained the ability to walk with little assistance and was discharged home. In conclusion, normal NCS findings up to several weeks do not exclude the diagnosis of GBS. Very proximal axonal conduction failure with late distal axonal degeneration should be taken into consideration, and electrodiagnostic follow-up examinations, even employing unusual techniques, are recommended over several weeks after disease onset.

The aim of this study was to identify Pseudomonas spp. in raw milk and investigate their associated proteolytic properties at low temperatures. Raw milk samples (n = 87) were collected from 87 bulk tanks in Shaanxi Province in China. Pseudomonas spp. were identified using Pseudomonas specific 16S, universal 16S rRNA sequencing, and rpoB gene sequencing. The proteolytic properties of Pseudomonas spp. were examined using milk agar, quantitative trinitrobenzenesulfonic acid assay, and by the presence of alkaline metallopeptidase gene (aprX). A total 143 isolates from all 87 samples were confirmed as Pseudomonas, and were identified as belonging to 14 Pseudomonas species. Of these, 40 (28.0%) isolates revealed proteolysis on milk agar at 2 degrees C, 74 (51.8%) at 4 degrees C, 104 (72.7%) at 7 degrees C, and 102 (71.3%) at 10 degrees C. However, proteolytic activity of 45 (31.5%) isolates exceeded 2 MUmol of glycine equivalents per mL at 7 degrees C, followed by 43 (30.1%) at 10 degrees C, 18 (12.6%) at 4 degrees C, and 7 (4.9%) at 2 degrees C. The results reveal proteolytic activity of Pseudomonas spp. present in milk and their spoilage potential at different temperatures. PMID- 29167661 TI - Investigating the Effect of Growth Phase on the Surface-Layer Associated Proteome of Lactobacillus acidophilus Using Quantitative Proteomics. AB - Bacterial surface-layers (S-layers) are semi-porous crystalline arrays that self assemble to form the outermost layer of some cell envelopes. S-layers have been shown to act as scaffolding structures for the display of auxiliary proteins externally. These S-layer associated proteins have recently gained attention in probiotics due to their direct physical contact with the intestinal mucosa and potential role in cell proliferation, adhesion, and immunomodulation. A number of studies have attempted to catalog the S-layer associated proteome of Lactobacillus acidophilus NCFM under a single condition. However, due to the versatility of the cell surface, we chose to employ a multiplexing-based approach with the intention of accurately contrasting multiple conditions. In this study, a previously described lithium chloride isolation protocol was used to release proteins bound to the L. acidophilus S-layer during logarithmic and early stationary growth phases. Protein quantification values were obtained via TMT (tandem mass tag) labeling combined with a triple-stage mass spectrometry (MS3) method. Results showed significant growth stage-dependent alterations to the surface-associated proteome while simultaneously highlighting the sensitivity and reproducibility of the technology. Thus, this study establishes a framework for quantifying condition-dependent changes to cell surface proteins that can easily be applied to other S-layer forming bacteria.

AB - It has become apparent that gut microbiota is closely associated with cardiometabolic diseases (CMDs), and alteration in microbiome compositions is also linked to the host environment. Next generation sequencing (NGS) has facilitated in-depth studies on the effects of herbal medicine and functional food on gut microbiota. Both herbal medicine and functional food contain fiber, polyphenols and polysaccharides, exerting prebiotics-like activities in the prevention and treatment of CMDs. The administrations of herbal medicine and functional food lead to increased the abundance of phylum Bacteroidetes, and genus Akkermansia, Bifidobacteria, Lactobacillus, Bacteroides and Prevotella, while reducing phylum Firmicutes and Firmicutes/Bacteroidetes ratio in gut. Both herbal medicine and functional food interact with gut microbiome and alter the microbial metabolites including short-chain fatty acids (SCFAs), bile acids (BAs) and lipopolysaccharides (LPS), which are now correlated with metabolic diseases such as type 2 diabetes (T2D), obesity and non-alcoholic fatty liver disease (NAFLD). In addition, trimethylamine (TMA)-N-oxide (TMAO) is recently linked to atherosclerosis (AS) and cardiovascular disease (CVD) risks. Moreover, gut-organs axes may serve as the potential strategy for treating CMDs with the intervention of herbal medicine and functional food. In summary, a balance between herbal medicine and functional food rich in fiber, polyphenols and polysaccharides plays a vital role in modulating gut microbiota (phylum Bacteroidetes, Firmicutes and Firmicutes/Bacteroidetes ratio, and genus Akkermansia, Bifidobacteria, Lactobacillus, Bacteroides and Prevotella) through SCFAs, BAs, LPS and TMAO signaling regarding CMDs. Targeting gut-organs axes may serve as a new therapeutic strategy for CMDs by herbal medicine and functional food in the future. This review aims to summarize the balance between herbal medicine and functional food utilized for the prevention and treatment of CMDs through modulating gut microbiota. PMID- 29167662 TI - Site-Directed Mutagenesis Study Revealed Three Important Residues in Hc-DAF-22, a Key Enzyme Regulating Diapause of Haemonchus contortus. AB - Haemonchus contortus (H. contortus) is one of the most important parasites of small ruminants, especially goats and sheep. The complex life cycle of this nematode is a main obstacle for the control and prevention of haemonchosis. So far, a special form of arrested development called diapause different from the dauer stage in Caenorhabditis elegans (C. elegans) has been found in many parasitic nematodes. In our previous study, we have characterized a novel gene Hc daf-22 from H. contortus sharing high homology with Ce-daf-22 and functional analysis showed this gene has similar biological function with Ce-daf-22. In this study, Hc-daf-22 mutants were constructed using site-directed mutagenesis, and carried out rescue experiments, RNA interference (RNAi) experiments and in vitro enzyme activity analysis with the mutants to further explore the precise function site of Hc-DAF-22. The results showed that Hc-daf-22 mutants could be expressed in the rescued ok693 worms and the expression positions were mainly in the intestine which was identical with that of Hc-daf-22 rescued worms. Through lipid staining we found that Hc-daf-22 could rescue daf-22 mutant (ok693) from the fatty acid metabolism deficiency while Hc-daf-22 mutants failed. Brood size and body length analyses in rescue experiment along with body length and life span analyses in RNAi experiment elucidated that Hc-daf-22 resembled Ce-daf-22 in effecting the development and capacity of C. elegans and mutants impaired the function of Hc-daf-22. Together with the protease activity assay, this research revealed three important active resides 84C/299H/349H in Hc-DAF-22 by site directed mutagenesis. PMID- 29167663 TI - Metagenomic Analysis of the Gut Microbiome of the Common Black Slug Arion ater in Search of Novel Lignocellulose Degrading Enzymes. AB - Some eukaryotes are able to gain access to well-protected carbon sources in plant biomass by exploiting microorganisms in the environment or harbored in their digestive system. One is the land pulmonate Arion ater, which takes advantage of a gut microbial consortium that can break down the widely available, but difficult to digest, carbohydrate polymers in lignocellulose, enabling them to digest a broad range of fresh and partially degraded plant material efficiently. This ability is considered one of the major factors that have enabled A. ater to become one of the most widespread plant pest species in Western Europe and North America. Using metagenomic techniques we have characterized the bacterial diversity and functional capability of the gut microbiome of this notorious agricultural pest. Analysis of gut metagenomic community sequences identified abundant populations of known lignocellulose-degrading bacteria, along with well characterized bacterial plant pathogens. This also revealed a repertoire of more than 3,383 carbohydrate active enzymes (CAZymes) including multiple enzymes associated with lignin degradation, demonstrating a microbial consortium capable of degradation of all components of lignocellulose. This would allow A. ater to make extensive use of plant biomass as a source of nutrients through exploitation of the enzymatic capabilities of the gut microbial consortia. From this metagenome assembly we also demonstrate the successful amplification of multiple predicted gene sequences from metagenomic DNA subjected to whole genome amplification and expression of functional proteins, facilitating the low cost acquisition and biochemical testing of the many thousands of novel genes identified in metagenomics studies. These findings demonstrate the importance of studying Gastropod microbial communities. Firstly, with respect to understanding links between feeding and evolutionary success and, secondly, as sources of novel enzymes with biotechnological potential, such as, CAZYmes that could be used in the production of biofuel. PMID- 29167665 TI - Microbiological and Physicochemical Changes in Natural Green Heat-Shocked Alorena de Malaga Table Olives. AB - Preserving the highly appreciated natural freshness of Alorena de Malaga table olives and preventing their progressive darkening during processing is a major challenge. In this work, heat-shocked (60 degrees C, 5 min) fruits were processed according to the three denominations referred to in the Protected Designation of Origen (cured, fresh green, and traditional) and their characteristics compared with those that followed the habitual industrial process (controls). The results revealed that the effects of the heat treatment on the evolution of pH, titratable acidity, salt, sugar, organic acid, ethanol content, texture, and color of fruits as well as on microbial populations (yeasts and lactic acid bacteria) were slight in the case of the fresh green and cured presentations. However, the differences between heat-shocked and its control were remarkable in the traditional process. Notably, the heat treatment favored lactic acid fermentation, retention of the green appearance of the fruits, stability during packaging, and led to the highest sensory evaluation. The metagenomic analysis carried out at the end of the fermentation revealed the presence in all samples of three genera (Lactobacillus, Pediococcus, and Celerinatantimonas) which encompassed most of the sequences. The number of Lactobacillus sequences was statistically higher (p >= 0.05) in the case of traditional heat-shocked fruits than in its control. PMID- 29167664 TI - Metabolic Engineering of Oleaginous Yeasts for Production of Fuels and Chemicals. AB - Oleaginous yeasts have been increasingly explored for production of chemicals and fuels via metabolic engineering. Particularly, there is a growing interest in using oleaginous yeasts for the synthesis of lipid-related products due to their high lipogenesis capability, robustness, and ability to utilize a variety of substrates. Most of the metabolic engineering studies in oleaginous yeasts focused on Yarrowia that already has plenty of genetic engineering tools. However, recent advances in systems biology and synthetic biology have provided new strategies and tools to engineer those oleaginous yeasts that have naturally high lipid accumulation but lack genetic tools, such as Rhodosporidium, Trichosporon, and Lipomyces. This review highlights recent accomplishments in metabolic engineering of oleaginous yeasts and recent advances in the development of genetic engineering tools in oleaginous yeasts within the last 3 years. PMID- 29167666 TI - First Year of Israeli Newborn Screening for Severe Combined Immunodeficiency Clinical Achievements and Insights. AB - Severe combined immunodeficiency (SCID), the most severe form of T cell immunodeficiency, is detectable through quantification of T cell receptor excision circles (TRECs) in dried blood spots obtained at birth. Herein, we describe the results of the first year of the Israeli SCID newborn screening (NBS) program. This important, life-saving screening test is available at no cost for every newborn in Israel. Eight SCID patients were diagnosed through the NBS program in its first year, revealing an incidence of 1:22,500 births in the Israeli population. Consanguine marriages and Muslim ethnic origin were found to be a risk factor in affected newborns, and a founder effect was detected for both IL7Ralpha and DCLRE1C deficiency SCID. Lymphocyte subset analysis and TREC quantification in the peripheral blood appear to be sufficient for confirmation of typical and leaky SCID and ruling out false positive (FP) results. Detection of secondary targets (infants with non-SCID lymphopenia) did not significantly affect the management or outcomes of these infants in our cohort. In the general, non-immunodeficient population, TREC rises along with gestational age and birth weight, and is significantly higher in females and the firstborn of twin pairs. Low TREC correlates with both gestational age and birth weight in extremely premature newborns. Additionally, the rate of TREC increase per week consistently accelerates with gestational age. Together, these findings mandate a lower cutoff or a more lenient screening algorithm for extremely premature infants, in order to reduce the high rate of FPs within this group. A significant surge in TREC values was observed between 28 and 30 weeks of gestation, where median TREC copy numbers rise by 50% over 2 weeks. These findings suggest a maturational step in T cell development around week 29 gestation, and imply moderate to late preterms should be screened with the same cutoff as term infants. The SCID NBS program is still in its infancy, but is already bearing fruit in the early detection and improved outcomes of children with SCID in Israel and other countries. PMID- 29167667 TI - Bruton's Tyrosine Kinase: An Emerging Key Player in Innate Immunity. AB - Bruton's tyrosine kinase (BTK) was initially discovered as a critical mediator of B cell receptor signaling in the development and functioning of adaptive immunity. Growing evidence also suggests multiple roles for BTK in mononuclear cells of the innate immune system, especially in dendritic cells and macrophages. For example, BTK has been shown to function in Toll-like receptor-mediated recognition of infectious agents, cellular maturation and recruitment processes, and Fc receptor signaling. Most recently, BTK was additionally identified as a direct regulator of a key innate inflammatory machinery, the NLRP3 inflammasome. BTK has thus attracted interest not only for gaining a more thorough basic understanding of the human innate immune system but also as a target to therapeutically modulate innate immunity. We here review the latest developments on the role of BTK in mononuclear innate immune cells in mouse versus man, with specific emphasis on the sensing of infectious agents and the induction of inflammation. Therapeutic implications for modulating innate immunity and critical open questions are also discussed. PMID- 29167668 TI - A Practical Approach to Newborn Screening for Severe Combined Immunodeficiency Using the T Cell Receptor Excision Circle Assay. AB - Severe combined immunodeficiency (SCID) is a life-threatening condition of newborns and infants caused by defects in genes involved in T cell development. Newborn screening (NBS) for SCID using the T cell receptor excision circle (TREC) assay began in Wisconsin in 2008 and has been adopted or is being implemented by all states in 2017. It has been established that NBS using the TREC assay is extremely sensitive to detect SCID in the newborn period. Some controversies remain regarding how screening positives are handled by individual states, including when to perform confirmatory flow cytometry, what is the necessary diagnostic workup of patients, what infection prophylaxis measures should be taken, and when hematopoietic stem cell transplantation should occur. In addition, the TREC can also assay detect infants with T cell lymphopenia who are not severe enough to be considered SCID; management of these infants is also evolving. PMID- 29167669 TI - Iron Induces Anti-tumor Activity in Tumor-Associated Macrophages. AB - Tumor-associated macrophages (TAMs) frequently help to sustain tumor growth and mediate immune suppression in the tumor microenvironment (TME). Here, we identified a subset of iron-loaded, pro-inflammatory TAMs localized in hemorrhagic areas of the TME. The occurrence of iron-loaded TAMs (iTAMs) correlated with reduced tumor size in patients with non-small cell lung cancer. Ex vivo experiments established that TAMs exposed to hemolytic red blood cells (RBCs) were converted into pro-inflammatory macrophages capable of directly killing tumor cells. This anti-tumor effect could also be elicited via iron oxide nanoparticles. When tested in vivo, tumors injected with such iron oxide nanoparticles led to significantly smaller tumor sizes compared to controls. These results identify hemolytic RBCs and iron as novel players in the TME that repolarize TAMs to exert direct anti-tumor effector function. Thus, the delivery of iron to TAMs emerges as a simple adjuvant therapeutic strategy to promote anti cancer immune responses. PMID- 29167672 TI - Novel Concept of CD4-Mediated Activation of Regulatory T Cells for the Treatment of Graft-Versus-Host Disease. AB - Allogeneic hematopoietic stem cell transplantation is the only curative treatment option for several hematological malignancies and immune deficiency syndromes. Nevertheless, the development of a graft-versus-host disease (GvHD) after transplantation is a high risk and a severe complication with high morbidity and mortality causing therapeutic challenges. Current pharmacological therapies of GvHD lead to generalized immunosuppression followed by severe adverse side effects including infections and relapse of leukemia. Several novel cell-based immunomodulatory strategies for treatment or prevention of GvHD have been developed. Herein, thymus-derived regulatory T cells (tTreg), essential for the maintenance of peripheral immunologic tolerance, are in the focus of investigation. However, due to the limited number of tTreg in the peripheral blood, a complex, time- and cost-intensive in vitro expansion protocol is necessary for the production of an efficient cellular therapeutic. We demonstrated that activation of tTreg using the CD4-binding human immunodeficiency virus-1 protein gp120 leads to a substantially increased suppressor activity of tTreg without the need for additional expansion. Gp120 activated tTreg prevent GvHD development in a preclinical humanized mouse model. In addition, gp120 is not only effective in prevention but also in therapy of GvHD by suppressing all clinical symptoms and improving survival of treated mice. These data indicate that tTreg activation by gp120 is a feasible and potent strategy for significant functional improvement of tTreg as cellular therapeutic for GvHD treatment without the need of complicated, time-intensive, and expensive in vitro expansion of isolated tTreg. PMID- 29167670 TI - The Cholinergic System Modulates Memory and Hippocampal Plasticity via Its Interactions with Non-Neuronal Cells. AB - Degeneration of central cholinergic neurons impairs memory, and enhancement of cholinergic synapses improves cognitive processes. Cholinergic signaling is also anti-inflammatory, and neuroinflammation is increasingly linked to adverse memory, especially in Alzheimer's disease. Much of the evidence surrounding cholinergic impacts on the neuroimmune system focuses on the alpha7 nicotinic acetylcholine (ACh) receptor, as stimulation of this receptor prevents many of the effects of immune activation. Microglia and astrocytes both express this receptor, so it is possible that some cholinergic effects may be via these non neuronal cells. Though the presence of microglia is required for memory, overactivated microglia due to an immune challenge overproduce inflammatory cytokines, which is adverse for memory. Blocking these exaggerated effects, specifically by decreasing the release of tumor necrosis factor alpha (TNF alpha), interleukin 1beta (IL-1beta), and interleukin 6 (IL-6), has been shown to prevent inflammation-induced memory impairment. While there is considerable evidence that cholinergic signaling improves memory, fewer studies have linked the "cholinergic anti-inflammatory pathway" to memory processes. This review will summarize the current understanding of the cholinergic anti-inflammatory pathway as it relates to memory and will argue that one mechanism by which the cholinergic system modulates hippocampal memory processes is its influence on neuroimmune function via the alpha7 nicotinic ACh receptor. PMID- 29167673 TI - Inhibition of Allograft Inflammatory Factor-1 in Dendritic Cells Restrains CD4+ T Cell Effector Responses and Induces CD25+Foxp3+ T Regulatory Subsets. AB - Allograft inflammatory factor-1 (AIF1) is a cytoplasmic scaffold protein shown to influence immune responses in macrophages and microglial cells. The protein contains Ca2+ binding EF-hand and PDZ interaction domains important for mediating intracellular signaling complexes. This study now reports that AIF1 is expressed in CD11c+ dendritic cells (DC) and silencing of expression restrains induction of antigen-specific CD4+ T cell effector responses. AIF1 knockdown in murine DC resulted in impaired T cell proliferation and skewed polarization away from T helper type 1 and 17 fates. In turn, there was a parallel expansion of IL-10 producing and CD25+Foxp3+ T regulatory subsets. These studies are the first to demonstrate that AIF1 expression in DC serves as a potent governor of cognate T cell responses and presents a novel target for engineering tolerogenic DC-based immunotherapies. PMID- 29167671 TI - Immune Checkpoint Targets for Host-Directed Therapy to Prevent and Treat Leishmaniasis. AB - Leishmaniasis encompasses a group of diseases caused by protozoan parasites belonging to the genus Leishmania. These diseases range from life threatening visceral forms to self-healing cutaneous lesions, and each disease manifestations can progress to complications involving dissemination of parasites to skin or mucosal tissue. A feature of leishmaniasis is the key role host immune responses play in disease outcome. T cells are critical for controlling parasite growth. However, they can also contribute to disease onset and progression. For example, potent regulatory T cell responses can develop that suppress antiparasitic immunity. Alternatively, hyperactivated CD4+ or CD8+ T cells can be generated that cause damage to host tissues. There is no licensed human vaccine and drug treatment options are often limited and problematic. Hence, there is an urgent need for new strategies to improve the efficacy of current vaccine candidates and/or enhance both antiparasitic drug effectiveness and subsequent immunity in treated individuals. Here, we describe our current understanding about host immune responses contributing to disease protection and progression in the various forms of leishmaniasis. We also discuss how this knowledge may be used to develop new strategies for host-directed immune therapy to prevent or treat leishmaniasis. Given the major advances made in immune therapy in the cancer and autoimmune fields in recent years, there are significant opportunities to ride on the back of these successes in the infectious disease domain. Conversely, the rapid progress in our understanding about host immune responses during leishmaniasis is also providing opportunities to develop novel immunotherapy strategies that could have broad applications in diseases characterized by inflammation or immune dysfunction. PMID- 29167674 TI - A New Immunosuppressive Molecule Emodin Induces both CD4+FoxP3+ and CD8+CD122+ Regulatory T Cells and Suppresses Murine Allograft Rejection. AB - Due to vigorous alloimmunity, an allograft is usually rejected without any conventional immunosuppressive treatment. However, continuous global immunosuppression may cause severe side effects, including tumors and infections. Mounting evidence has shown that cyclosporine (CsA), a common immunosuppressant used in clinic, impedes allograft tolerance by dampening regulatory T cells (Tregs), although it inhibits allograft rejection at the same time. Therefore, it is necessary to seek an alternative immunosuppressive drug that spares Tregs with high efficiency in suppression but low toxicity. In this study, we investigated the capacity of emodin, an anthraquinone molecule originally extracted from certain natural plants, to prolong transplant survival in a mouse model and explored the cellular and molecular mechanisms underlying its action. We found that emodin significantly extended skin allograft survival and hindered CD3+ T cell infiltration in the allograft, accompanied by an increase in CD4+Foxp3+ and CD8+CD122+ Treg frequencies and numbers but a reduction in effector CD8+CD44highCD62Llow T cells in recipient mice. Emodin also inhibited effector CD8+ T cells proliferation in vivo. However, CD4+CD25+, but not CD8+CD122+, Tregs derived from emodin-treated recipients were more potent in suppression of allograft rejection than those isolated from control recipients, suggesting that emodin also enhances the suppressive function of CD4+CD25+ Tregs. Interestingly, depleting CD25+ Tregs largely reversed skin allograft survival prolonged by emodin while depleting CD122+ Tregs only partially abrogated the same allograft survival. Furthermore, we found that emodin hindered dendritic cell (DC) maturation and reduced alloantibody production posttransplantation. Finally, we demonstrated that emodin inhibited in vitro proliferation of T cells and blocked their mTOR signaling as well. Therefore, emodin may be a novel mTOR inhibitor that suppresses alloimmunity by inducing both CD4+FoxP3+ and CD8+CD122+ Tregs, suppressing alloantibody production, and hindering DC maturation. Thus, emodin is a newly emerging immunosuppressant and could be utilized in clinical transplantation in the future. PMID- 29167675 TI - Boron Deficiency in Trifoliate Orange Induces Changes in Pectin Composition and Architecture of Components in Root Cell Walls. AB - Boron (B) is a micronutrient indispensable for citrus and B deficiency causes a considerable loss of productivity and quality in China. However, studies on pectin composition and architecture of cell wall components in trifoliate orange roots under B deficiency condition are not sufficient. In this study, we investigated the alteration in pectin characteristics and the architecture of cell wall components in trifoliate orange [Poncirus trifoliata (L.) Raf.] roots under B starvation. The results showed that B-deficient roots resulted in a significant enlargement of root tips and an obvious decrease in cell wall B and uronic acid content in Na2CO3-soluble pectin compared with B-adequate roots. Meanwhile, they showed a decrease of 2-keto-3-deoxyoctanoic acid in CDTA-soluble and Na2CO3-soluble pectin in cell walls, while the degree of methylation (DM) of CDTA-soluble pectin was significantly increased under B deficiency. Transmission electron microscope (TEM) micrographs of B deficient plants showed a distinct thickening of the cell walls, with the thickness 1.82 times greater than that of control plant roots. The results from Fourier-transform infrared spectroscopy (FTIR) showed that B deficiency changed the mode of hydrogen bonding between protein and carbohydrates (cellulose and hemicellulose). The FTIR spectra exhibited a destroyed protein structure and accumulation of wax and cellulose in the cell walls under B starvation. The 13C nuclear magnetic resonance (13C-NMR) spectra showed that B starvation changed the organic carbon structure of cell walls, and enhanced the contents of amino acid, cellulose, phenols, and lignin in the cell wall. The results reveal that the swelling and weakened structural integrity of cell walls, which induced by alteration on the network of pectin and cell wall components and structure in B-deficient roots, could be a major cause of occurrence of the rapid interruption of growth and significantly enlarged root tips in trifoliate orange roots under B-insufficient condition. PMID- 29167676 TI - The Effect of Season-Long Temperature Increases on Rice Cultivars Grown in the Central and Southern Regions of China. AB - Rice production is challenged by the asymmetric increases in day and night temperatures. Efforts are required to improve our understanding of the impact of climate change on rice production. To this end, 2-year experiment was conducted to evaluate the response of mid-season rice growth in the central and southern regions of China to elevated temperatures. Four replicates of four widely planted indica rice cultivars (Huanghuazhan: HHZ; Shanyou63: SY63; Yangliangyou6: YLY6; Liangyoupeijiu: LYPJ) were subjected to four elevated-temperature treatments (control: ambient temperature; NW: night-time warming; DW: daytime warming; AW: all-day warming) generated by an open-top hot-blast system under field conditions. This apparatus causes an ~2 degrees C increase in the rice canopy temperature. Of all the elevated-temperature treatments, AW was the most devastating treatment for all rice cultivars, negatively affecting nearly all of investigated parameters, including grain yield and its components, dry matter accumulation, biomass, and harvest index (HI). The AW treatment decreased the grain yield by 11-35% and 43-78% in 2015 and 2016, respectively. No significant reduction in the grain yield was observed in the DW and NW treatments in 2015. However, the grain yield was decreased in DW and NW treatments by 20-52% and 18 55%, respectively, in 2016. Furthermore, the temperature-driven degradation of pollen viability, the number of pollen grains adhering to the stigma and pollen germination on the stigma caused spikelet sterility and thereby decreased the grain yield. The YLY6 and SY63 cultivars performed better than the HHZ and LYPJ cultivars with respect to grain yield and its components in all elevated temperature treatments in both years. However, 42.97 and 61.01% reductions still occurred for the SY63 and YLY6 cultivars, respectively, in the AW treatment in 2016. The above results suggested that the elevated temperature may cause a noteworthy reduction in the productions of these widely planted genotypes in central and southern regions of China. To ensure the security of rice production in this region in an expected global warming environment, currently planted varieties will need to be replaced by heat-resistant varieties in the future. PMID- 29167677 TI - Effect of Trait Heritability, Training Population Size and Marker Density on Genomic Prediction Accuracy Estimation in 22 bi-parental Tropical Maize Populations. AB - Genomic selection is being used increasingly in plant breeding to accelerate genetic gain per unit time. One of the most important applications of genomic selection in maize breeding is to predict and select the best un-phenotyped lines in bi-parental populations based on genomic estimated breeding values. In the present study, 22 bi-parental tropical maize populations genotyped with low density SNPs were used to evaluate the genomic prediction accuracy (rMG ) of the six trait-environment combinations under various levels of training population size (TPS) and marker density (MD), and assess the effect of trait heritability (h2 ), TPS and MD on rMG estimation. Our results showed that: (1) moderate rMG values were obtained for different trait-environment combinations, when 50% of the total genotypes was used as training population and ~200 SNPs were used for prediction; (2) rMG increased with an increase in h2 , TPS and MD, both correlation and variance analyses showed that h2 is the most important factor and MD is the least important factor on rMG estimation for most of the trait environment combinations; (3) predictions between pairwise half-sib populations showed that the rMG values for all the six trait-environment combinations were centered around zero, 49% predictions had rMG values above zero; (4) the trend observed in rMG differed with the trend observed in rMG /h, and h is the square root of heritability of the predicted trait, it indicated that both rMG and rMG /h values should be presented in GS study to show the accuracy of genomic selection and the relative accuracy of genomic selection compared with phenotypic selection, respectively. This study provides useful information to maize breeders to design genomic selection workflow in their breeding programs. PMID- 29167678 TI - A Radish Basic Helix-Loop-Helix Transcription Factor, RsTT8 Acts a Positive Regulator for Anthocyanin Biosynthesis. AB - The MYB-bHLH-WDR (MBW) complex activates anthocyanin biosynthesis through the transcriptional regulation. RsMYB1 has been identified as a key player in anthocyanin biosynthesis in red radish (Raphanus sativus L.), but its partner bHLH transcription factor (TF) remains to be determined. In this study, we isolated a bHLH TF gene from red radish. Phylogenetic analysis indicated that this gene belongs to the TT8 clade of the IIIF subgroup of bHLH TFs, and we thus designated this gene RsTT8. Subcellular localization analysis showed that RsTT8 sGFP was localized to the nuclei of Arabidopsis thaliana protoplasts harboring the RsTT8-sGFP construct. We evaluated anthocyanin biosynthesis and RsTT8 expression levels in three radish varieties (N, C, and D) that display different red phenotypes in the leaves, root flesh, and root skins. The root flesh of the C variety and the leaves and skins of the D variety exhibit intense red pigmentation; in these tissues, RsTT8 expression showed totally positive association with the expression of RsMYB1 TF and of five of eight tested anthocyanin biosynthesis genes (i.e., RsCHS, RsCHI, RsF3H, RsDFR, and RsANS). Heterologous co-expression of both RsTT8 and RsMYB1 in tobacco leaves dramatically increased the expression of endogenous anthocyanin biosynthesis genes and anthocyanin accumulation. Furthermore, a yeast two-hybrid assay showed that RsTT8 interacts with RsMYB1 at the MYB-interacting region (MIR), and a transient transactivation assay indicated that RsTT8 activates the RsCHS and RsDFR promoters when co-expressed with RsMYB1. Complementation of the Arabidopsis tt8-1 mutant, which lacks red pigmentation in the leaves and seeds, with RsTT8 restored red pigmentation, and resulted in high anthocyanin and proanthocyanidin contents in the leaves and seeds, respectively. Together, these results show that RsTT8 functions as a regulatory partner with RsMYB1 during anthocyanin biosynthesis. PMID- 29167679 TI - Effects of Mountain Uplift and Climatic Oscillations on Phylogeography and Species Divergence in Four Endangered Notopterygium Herbs. AB - Mountain uplift and climatic fluctuations are important driving forces that have affected the geographic distribution and population dynamics history of organisms. However, it is unclear how geological and climatic events might have affected the phylogeographic history and species divergence in high-alpine herbal plants. In this study, we analyzed the population demographic history and species differentiation of four endangered Notopterygium herbs on the high-altitude Qinghai-Tibetan Plateau (QTP) and adjacent areas. We combined phylogeographic analysis with species distribution modeling to detect the genetic variations in four Notopterygium species (N. incisum, N. franchetii, N. oviforme, and N. forrestii). In total, 559 individuals from 74 populations of the four species were analyzed based on three maternally inherited chloroplast fragments (matK, rbcL, and trnS-trnG) and one nuclear DNA region (internal transcribed spacer, ITS). Fifty-five chloroplast DNA (cpDNA) and 48 ITS haplotypes were identified in the four species. All of the cpDNA and ITS haplotypes were species-specific, except N. franchetii and N. oviforme shared one cpDNA haplotype, H32. Phylogenetic analysis suggested that all four species formed a monophyletic clade with high bootstrap support, where N. franchetii and N. oviforme were sisters. In addition, each Notopterygium species generated an individual clade that corresponded to their respective species in the ITS tree. Population dynamics analyses and species distribution modeling showed that the two widely distributed herbs N. incisum and N. franchetii exhibited obvious demographic expansions during the Pleistocene ice ages. Molecular dating suggested that the divergence of the four Notopterygium species occurred approximately between 3.6 and 1.2 Mya, and it was significantly associated with recent extensive uplifts of the QTP. Our results support the hypothesis that mountain uplift and Quaternary climatic oscillations profoundly shaped the population genetic divergence and demographic dynamics of Notopterygium species. The findings of this and previous studies provide important insights into the effects of QTP uplifts and climatic changes on phylogeography and species differentiation in high altitude mountainous areas. Our results may also facilitate the conservation of endangered herbaceous medicinal plants in the genus Notopterygium. PMID- 29167680 TI - Gene Editing and Crop Improvement Using CRISPR-Cas9 System. AB - Advancements in Genome editing technologies have revolutionized the fields of functional genomics and crop improvement. CRISPR/Cas9 (clustered regularly interspaced short palindromic repeat)-Cas9 is a multipurpose technology for genetic engineering that relies on the complementarity of the guideRNA (gRNA) to a specific sequence and the Cas9 endonuclease activity. It has broadened the agricultural research area, bringing in new opportunities to develop novel plant varieties with deletion of detrimental traits or addition of significant characters. This RNA guided genome editing technology is turning out to be a groundbreaking innovation in distinct branches of plant biology. CRISPR technology is constantly advancing including options for various genetic manipulations like generating knockouts; making precise modifications, multiplex genome engineering, and activation and repression of target genes. The review highlights the progression throughout the CRISPR legacy. We have studied the rapid evolution of CRISPR/Cas9 tools with myriad functionalities, capabilities, and specialized applications. Among varied diligences, plant nutritional improvement, enhancement of plant disease resistance and production of drought tolerant plants are reviewed. The review also includes some information on traditional delivery methods of Cas9-gRNA complexes into plant cells and incorporates the advent of CRISPR ribonucleoproteins (RNPs) that came up as a solution to various limitations that prevailed with plasmid-based CRISPR system.

AB - Background: Hypoxic conditions induce the expression of hypoxia-inducible factors (HIFs) that allow cells to adapt to the changing conditions and alter the expression of a number of genes including the cystic fibrosis transmembrane conductance regulator (CFTR). CFTR is a low abundance mRNA in airway epithelial cells even during normoxic conditions, but during hypoxia its mRNA expression decreases even further. Methods: In the current studies, we examined the kinetics of hypoxia-induced changes in CFTR mRNA and protein levels in two human airway epithelial cell lines, Calu-3 and 16HBE14o-, and in normal primary bronchial epithelial cells. Our goal was to examine the posttranscriptional modifications that affected CFTR expression during hypoxia. We utilized in silico predictive protocols to establish potential miRNAs that could potentially regulate CFTR message stability and identified miR-200b as a candidate molecule. Results: Analysis of each of the epithelial cell types during prolonged hypoxia revealed that CFTR expression decreased after 12 h during a time when miR-200b was continuously upregulated. Furthermore, manipulation of the miRNA levels during normoxia and hypoxia using miR-200b mimics and antagomirs decreased and increased CFTR mRNA levels, respectively, and thus established that miR-200b downregulates CFTR message levels during hypoxic conditions. Conclusion: The data suggest that miR-200b may be a suitable target for modulating CFTR levels in vivo.

AB - Objectives: This study sought to assess the root morphology and root canal anatomy of the maxillary first and second molars in an Iranian population using cone-beam computed tomography (CBCT). Materials and Methods: Sound fully developed maxillary first (n=345) and second (n=423) molars were evaluated on 450 CBCT scans ordered for pre-operative assessment for implant placement. The (I) number of roots and their morphology (II) number of canals per root, (III) canal configuration and presence of a second mesiobuccal canal according to the Vertucci's classification and (IV) unilateral or bilateral occurrence of a second mesiobuccal canal (MB2) were evaluated. Results: Single roots were found in 1.1% of the first and 11.3% of the second molars. Four separate roots were identified in 0.5% of the first molars; none of the second molars had four separate roots. First and second molars showed a higher prevalence of three separate roots of mesiobuccal, distobuccal and palatal with one canal in each root (54% and 86 %, respectively). The most common anatomical variation in the maxillary first molars was related to the configuration of the MB root; the root canal system of the maxillary second molars showed more anatomical variations. Conclusions: Mesiobuccal roots of the maxillary molars had more variations in their canal system than the distobuccal or palatal roots. The root canal configuration of the maxillary second molars was more diverse than that of first molars; CBCT enhances mapping of the mesiobuccal root canal system with the potential to improve the quality of root canal treatment.

AB - Objectives: This study aimed to assess and compare the microleakage of two bulk fill and one conventional composite in class II restorations of primary posterior teeth. Materials and Methods: This in vitro, experimental study was conducted on 60 primary mandibular second molars, which were randomly divided into three groups. Standard class II cavities were prepared in teeth and restored with 3M bulk fill composite in group 1, SonicFill bulk fill composite in group 2 and Z250 conventional composite in group 3. Single Bond 2 bonding agent was used in all cavities. The teeth were then thermocycled and immersed in 1M silver nitrate solution. The teeth were then mesiodistally sectioned and evaluated under a stereomicroscope at*10 magnification. Dye penetration depth was recorded in microns and data were analyzed using one-way ANOVA. Results: The mean (+/- standard deviation) dye penetration depth in the gingival margins was 543+/ 523MUm, 343+/-290MUm and 597+/-590MUm for 3M bulk fill, SonicFill and Z250 conventional composite, respectively. These values were 214+/-93MUm, 302+/-127MUm and 199+/-145MUm in the occlusal margins, respectively. The three groups were not significantly different in terms of occlusal or gingival microleakage (P>0.05), but gingival margins showed significantly higher microleakage than occlusal margins in all three groups (P<0.05). Conclusions: Bulk fill composites are not significantly different from conventional composites in terms of microleakage. PMID- 29167684 TI - Demographic Profile of Non-Odontogenic Jaw Lesions in an Iranian Population: A 30 Year Archive Review. AB - Objectives: The frequency of non-odontogenic lesions of the jawbones is lower than that of odontogenic lesions; however, study of the epidemiologic data of these lesions is required for health care programs. This study aimed to assess the relative frequency and demographic profile of non-odontogenic jaw lesions in an Iranian population over a 30-year period. Materials and Methods: This archive review was performed using demographic and biopsy information of all patients with non-odontogenic lesions of the jawbones submitted to the Oral Pathology Department of Dental School of Tehran University of Medical Sciences from 1984 to 2014. Demographic data included in the study were: age at diagnosis, gender and location of lesion. The lesions were divided into three groups of group 1: cystic lesions, group 2: tumors and tumor-like lesions, and group 3: infectious/inflammatory/reactive lesions. Frequency and clinical data were analyzed using SPSS 22. Results: Of 972 non-odontogenic jaw lesions, the ratio of mandibular to maxillary lesions was 1.63:1. Female to male ratio was 1.33:1 and the mean age of patients was 29.09+/-16.90 years. The most common non-odontogenic jaw lesion was central giant cell granuloma (CGCG). In groups 1, 2 and 3, nasopalatine duct cyst, CGCG, and osteomyelitis were the most frequent lesions, respectively. Conclusions: Non-odontogenic lesions of the jawbones are a diverse group of lesions with different frequency and behavior. This study demonstrated that tumors and tumor-like lesions of the jaws were more common than cystic and infectious/inflammatory/reactive lesions. Overall, the most common non odontogenic jaw lesion was CGCG. PMID- 29167685 TI - Effect of Music Practice on Anxiety and Depression of Iranian Dental Students. AB - Objectives: The practice of dentistry has long been associated with high levels of occupational stress and anxiety and music has been shown as a method of reducing stress. Considering the reportedly high level of stress among dental students and its consequences and also considering the positive effect of music therapy, the aim of this study was to evaluate the relationship between music practice and level of stress in dental students. Materials and Methods: In this analytical, cross-sectional study, 88 students, including 44 with a history of music practice and 44 matched controls without music practice who met the defined inclusion criteria, participated. Upon obtaining written informed consent, all volunteers filled the Beck anxiety inventory (BAI) and Beck depression inventory (BDI) questionnaires. Data were analyzed using the Kolmogorov-Smirnov test, and multiple linear regression test with backward method was used to evaluate the effect of demographic factors on anxiety and depression scores. Results: The level of anxiety was higher in students who did not have music practice and this difference was significant (P<0.001). The same was observed for depression (P=0.027). Other factors including age, gender, and being far from family had no significant effect on depression and anxiety (P>0.05). But level of anxiety and depression was higher in students of universities with tuition fee compared to free public institutes (P<0.05). Conclusions: It may be concluded that music practice can reduce anxiety and depression of dental students. PMID- 29167686 TI - Comparison of Enamel Morphologic Characteristics after Conditioning with Various Combinations of Acid Etchant and Er:YAG Laser in Bonding and Rebonding Procedures: A SEM Analysis. AB - Objectives: Many studies have evaluated re-etched enamel by using scanning electron microscopy (SEM); however, there is no evidence regarding the use of Erbium-doped yttrium aluminium garnet (Er:YAG) laser at primary and secondary bonding instead of acid etching with regards to enamel surface changes. The purpose of the present study was to determine that whether or not the methods of primary and secondary enamel preparation affect enamel characteristics after rebonding, by using SEM analysis. Materials and Methods: Twelve freshly extracted premolars were divided into 4 groups. The samples in each group were conditioned by acid etchant or Er:YAG laser at primary conditioning, according to the instructions. Afterwards, they were bonded with orthodontic brackets. After debonding, the samples were prepared for second conditioning. Also, two samples were conditioned only once with acid etchant or laser, to compare enamel morphology changes with those after re-etching. Finally, buccal enamel surfaces were evaluated using SEM. Results: Enamel etching patterns were observed in the samples which had been acid-conditioned at first or at both conditionings. The samples irradiated by Er:YAG laser showed amorphous and irregular surfaces, with no signs of typical etching patterns. A large deep gap was seen in one of the samples irradiated with laser at primary and secondary conditionings, which might have penetrated the underling layers of enamel and dentin. Conclusions: Enamel surface preparation with Er:YAG laser produces irregular and indistinct morphologic changes, completely different from those produced after acid etching at both conditioning and reconditioning. Therefore, it is recommended to use this laser with caution to avoid permanent enamel damage. PMID- 29167687 TI - Effect of Self-Adhesive and Separate Etch Adhesive Dual Cure Resin Cements on the Bond Strength of Fiber Post to Dentin at Different Parts of the Root. AB - Objectives: Bonding of fiber posts to intracanal dentin is challenging in the clinical setting. This study aimed to compare the effect of self-adhesive and separate etch adhesive dual cure resin cements on the bond strength of fiber post to dentin at different parts of the root. Materials and Methods: This in-vitro experimental study was conducted on 20 single-rooted premolars. The teeth were decoronated at 1mm coronal to the cementoenamel junction (CEJ), and the roots underwent root canal treatment. Post space was prepared in the roots. Afterwards, the samples were randomly divided into two groups. In group 1, the fiber posts were cemented using Rely X Unicem cement, while in group 2, the fiber posts were cemented using Duo-Link cement, according to the manufacturer's instructions. The intracanal post in each root was sectioned into three segments of coronal, middle, and apical, and each cross-section was subjected to push-out bond strength test at a crosshead speed of 1mm/minute until failure. Push-out bond strength data were analyzed using independent t-test and repeated measures ANOVA. Results: The bond strength at the middle and coronal segments in separate etch adhesive cement group was higher than that in self-adhesive cement group. However, the bond strength at the apical segment was higher in self-adhesive cement group compared to that in the other group. Overall, the bond strength in separate etch adhesive cement group was significantly higher than that in self adhesive cement group (P<0.001). Conclusions: Bond strength of fiber post to intracanal dentin is higher after the use of separate etch adhesive cement compared to self-adhesive cement. PMID- 29167688 TI - Effect of Quaternary Ammonium Salt on Shear Bond Strength of Orthodontic Brackets to Enamel. AB - Objectives: This study sought to assess the effect of quaternary ammonium salt (QAS) on shear bond strength of orthodontic brackets to enamel. Materials and Methods: In this in vitro experimental study, 0, 10, 20 and 30% concentrations of QAS were added to Transbond XT primer. Brackets were bonded to 60 premolar teeth using the afore-mentioned adhesive mixtures, and the shear bond strength of the four groups (n=15) was measured using a universal testing machine. After debonding, the adhesive remnant index (ARI) score was determined under a stereomicroscope. Data were analyzed using one-way ANOVA. Results: The mean and standard deviation of shear bond strength of the control and 10%, 20% and 30% groups were 23.54+/-6.31, 21.81+/-2.82, 20.83+/-8.35 and 22.91+/-5.66 MPa, respectively. No significant difference was noted in shear bond strength of the groups (P=0.83). Study groups were not different in terms of ARI scores (P=0.80). Conclusions: The results showed that addition of QAS to Transbond XT primer had no adverse effect on shear bond strength of orthodontic brackets. PMID- 29167689 TI - Fatigue Fracture Strength of Implant-Supported Full Contour Zirconia and Metal Ceramic Fixed Partial Dentures. AB - Objectives: Zirconia restorations have been suggested as a more durable and more appealing alternative to metal restorations. However, their mechanical properties may be negatively affected by fatigue due to superficial stresses or low temperature degradation. This study aimed to assess the fatigue fracture strength of three-unit implant-supported full contour zirconia and pre-sintered cobalt chromium (Co-Cr) alloy posterior fixed partial dentures (FPDs). Materials and Methods: In this in-vitro experimental study, 28 posterior three-unit implant supported FPDs were fabricated of full contour zirconia and pre-sintered Co-Cr alloy, and were cemented on implant abutments. To simulate the oral environment, FPDs were subjected to 10,000 thermal cycles between 5-55 degrees C for 30 seconds, and were then transferred to a chewing simulator (100,000 cycles, 50 N, 0.5 Hz). Afterwards, fatigue fracture strength was measured using a universal testing machine. Data were analyzed by Mann-Whitney U test. Results: The mean and standard deviation of fracture strength were 2108.6+/-440.1 N in full contour zirconia, and 3499.9+/-1106.5 N in pre-sintered Co-Cr alloy. According to Mann Whitney U test, the difference in this respect was statistically significant between the two groups (P=0.007). Conclusions: Since the fracture strength values obtained in the two groups were significantly higher than the maximum mean masticatory load in the oral environment, both materials can be used for fabrication of posterior three-unit FPDs, depending on the esthetic demands of patients. PMID- 29167690 TI - Synchronous GISTs associated with multiple sporadic tumors: a case report. AB - Gastrointestinal stromal tumors (GISTs) are rare neoplasms, but they also represent the most common mesenchymal tumors of the gastrointestinal tract originating from the cell of Cajal. GIST incidence ranges around 1% of all gastrointestinal malignancies. Approximately 5% of all GISTs have a hereditary etiology. The remaining 95% of GISTs are considered sporadic events, with up to 75% of cases driven by a constitutional activation of the c-KIT proto-oncogene. GISTs are generally solitary lesions. Nonetheless, multiple sporadic GISTs can occur and present as synchronous or metachronous tumors, usually associated with familial GIST. Here, we report a case of primary prostate and lung tumors associated with gastric and small bowel GISTs, unrelated to any known hereditary syndrome. Also, in the case we describe, the prostatic tumor came before the GISTs, while the lung tumor occurred later in time and led to pulmonary lobectomy plus lymphoadenectomy, with a diagnosis of nonsmall cell lung cancer. With the exception of a slight difference in lymphoid infiltration, the abdominal and gastric GIST nodules shared the same proliferative MIB1 index and mitotic count. However, the genetic analysis revealed that the gastric GIST and abdominal tumors were characterized by two different c-KIT mutations. This molecular heterogeneity supported the hypothesis of two different synchronous GISTs arising from stomach and ileum. At present, the patient is disease free and has already completed the third year of adjuvant therapy with imatinib. This case supports the importance of the analysis of c-KIT mutational status to distinguish metastases from synchronous multicentric GISTs, with relevant implications in therapeutic decisions, as well as the importance of a dedicated multidisciplinary team and of a radiological follow-up after the diagnosis of a primary GIST, to discover a relapse of the GIST or, possibly, additional malignancies. PMID- 29167691 TI - Long-term efficacy and safety of fourth-line multikinase inhibitor treatment with lenvatinib in a young papillary thyroid carcinoma patient. AB - Lenvatinib, a multikinase inhibitor, is approved for the treatment of patients with radioiodine-refractory metastatic thyroid cancer on the basis of a Phase III, prospective, double-blind, randomized, placebo-controlled trial that showed longer progression-free survival in the drug-treated arm. Here, we report the case of a young papillary thyroid cancer patient, pretreated with three other kinase inhibitors, who achieved a long-term clinical benefit from lenvatinib in the fourth-line setting. PMID- 29167692 TI - Prognostic and predictive factors of eribulin efficacy in heavily pretreated patients affected by metastatic breast cancer: correlation with tumor biology and previous therapies. AB - Background: Eribulin mesylate is currently approved in the United States and Europe for the treatment of metastatic breast cancer (MBC). Scope: The objective of this retrospective study is to find specific predictive criteria related to patient or tumor characteristics in order to select patients that might benefit the most from eribulin and define the correct treatment sequence. Findings: Forty four patients with MBC who received eribulin in third or subsequent lines of therapy in a single Italian center were considered eligible. Patients were stratified by body mass index, hormonal/HER2 status, and previous therapies. Primary endpoint was progression free survival (PFS), whereas secondary endpoint was disease control rate (DCR).A longer PFS was found in patients with hormone positive tumors (p=0.0051), in HER2-negative cases (p=0.037), and in overweight patients (p=0.0015). No difference in efficacy was observed when eribulin was administered in third or subsequent lines of therapy. Significantly longer PFS (p<0.0001) and higher DCR (p=0.035) were achieved by patients previously treated with paclitaxel-bevacizumab in comparison to those pretreated with other drug combinations or with anthracyclines. Prior treatment with nab-paclitaxel seems to have a detrimental effect on PFS (p=0.0008). Conclusion: Hormone and HER2 status seems a good predictive and prognostic indicator of response to eribulin. Efficacy seems independent from the number of prior therapies, and it is not influenced by prior endocrine treatments and anthracyclines-containing regimens. On the other hand, sensitivity to a prior treatment with paclitaxel-bevacizumab might be predictive of response to eribulin. PMID- 29167693 TI - Approving cancer treatments based on endpoints other than overall survival: an analysis of historical data using the PACE Continuous Innovation IndicatorsTM (CII). AB - Background: There is an active debate about the role that endpoints other than overall survival (OS) should play in the drug approval process. Yet the term 'surrogate endpoint' implies that OS is the only critical metric for regulatory approval of cancer treatments. We systematically analyzed the relationship between U.S. Food and Drug Administration (FDA) approval and publication of OS evidence to understand better the risks and benefits of delaying approval until OS evidence is available. Scope: Using the PACE Continuous Innovation Indicators (CII) platform, we analyzed the effects of cancer type, treatment goal, and year of approval on the lag time between FDA approval and publication of first significant OS finding for 53 treatments approved between 1952 and 2016 for 10 cancer types (n = 71 approved indications). Findings: Greater than 59% of treatments were approved before significant OS data for the approved indication were published. Of the drugs in the sample, 31% had lags between approval and first published OS evidence of 4 years or longer. The average number of years between approval and first OS evidence varied by cancer type and did not reliably predict the eventual amount of OS evidence accumulated. Conclusions: Striking the right balance between early access and minimizing risk is a central challenge for regulators worldwide. We illustrate that endpoints other than OS have long helped to provide timely access to new medicines, including many current standards of care. We found that many critical drugs are approved many years before OS data are published, and that OS may not be the most appropriate endpoint in some treatment contexts. Our examination of approved treatments without significant OS data suggests contexts where OS may not be the most relevant endpoint and highlights the importance of using a wide variety of fit-for-purpose evidence types in the approval process. PMID- 29167694 TI - Computational modeling to improve treatments for essential tremor. AB - Essential tremor (ET) is a neurological disorder of unknown etiology that is typically characterized by an involuntary periodic movement of the upper limbs. No longer considered monosymptomatic, ET patients often have additional motor and even cognitive impairments. Although there are several pharmacological treatments, no drugs have been developed specifically for ET [1], and 30-70% of patients are medication-refractory [2]. A subset of medication-refractory patients may benefit from electrical deep brain stimulation (DBS) of the ventral intermediate nucleus of the thalamus (VIM), which receives cerebellar inputs. Abnormal cerebellar input to VIM is presumed to be a major contributor to tremor symptoms, which is alleviated by DBS. Computational modeling of the effects of DBS in VIM has been a powerful tool to design DBS protocols to reduce tremor activity. However, far less is known about how these therapies affect non-tremor symptoms, and more experimental and computational modeling work is required to address these growing considerations. Models capable of addressing multiple facets of ET will lead to novel, more efficient treatment. PMID- 29167695 TI - Total energy expenditure of 10- to 12-year-old Japanese children measured using the doubly labeled water method. AB - Background: To establish Japanese children's estimated energy requirements, total energy expenditure (TEE) data measured using the doubly labeled water (DLW) method is needed. This study aimed to 1) obtain basic TEE data from Japanese children measured using DLW (TEEDLW), 2) compare TEEDLW with TEE estimated by various estimation formulas to calculate their accuracy, and 3) develop a new equation to estimate TEE using body composition and pedometers. Methods: TEE was measured using DLW in 56 10- to 12-year-old Japanese children (33 boys, 23 girls). Physical activity level (PAL) was calculated by dividing TEEDLW by estimated resting energy expenditure. To assess their physical activity, participants wore pedometers during the 7-d DLW period. Total body water was calculated from 2H and 18O; fat-free mass (FFM) and fat mass (FM) were then determined. Results: In boys and girls of normal weight, TEEDLW was 2067 +/- 230 kcal/d and 1830 +/- 262 kcal/d, respectively. Average PAL was 1.58 +/- 0.17. FFM was strongly related to TEE (r = 0.702, p < 0.01). After adjusting for FFM and FM, step count was significantly associated with TEE (r = 0.707, p < 0.01). The TEE estimation formula used in the Dietary Reference Intakes (DRI) for the United States and Canada estimated TEEDLW with high accuracy (bias: 2.0%) in both sexes. We developed new equations for TEE consisting of FFM and step count, which accounted for 68% and 65% of TEE variance in boys and girls, respectively: boys, 47.1 * FFM (kg) + 0.0568 * step count (steps/d) - 122, and girls, 55.5 * FFM (kg) + 0.0315 * step count (steps/d) - 117. Conclusions: The TEE in 10- to 12-year-old Japanese children measured using DLW was approximately 7% lower for boys and 12% lower for girls compared to the current Japanese DRI. If PAL can be accurately determined, the equation in the DRI for the United States and Canada may be applicable to Japanese children. In addition, TEE could be predicted using FFM and step count. PMID- 29167696 TI - Racial/ethnic differences in video game and Internet use among US adolescents with mental health and educational difficulties. AB - Video game and Internet use can be associated with poor mental health and educational outcomes among adolescents. Racial/ethnic minority youth use these media more than White youth. Video game and Internet use among adolescents with mental health and educational difficulties may therefore differ by race/ethnicity in clinically meaningful ways. We analyzed a representative sample of 8th grade students in the United States from the Early Childhood Longitudinal Survey Kindergarten (N=6,700). Stratifying by gender, we assessed racial/ethnic differences in the associations between video game and Internet use, mental health, and reading and math achievement. Significant minority-White differences were identified in associations between media use and mental health and educational achievement. Video game use was relatively high among black females with prior mental health diagnoses and Asian-American males with high internalizing symptoms. Understanding video game and Internet use among racial/ethnic minority youth with mental health and educational difficulties may improve clinical practice. PMID- 29167697 TI - Young lives disrupted: gender and well-being among adolescent Syrian refugees in Lebanon. AB - Background: The conflict in Syria that began in 2011 has resulted in the exodus of over 5 million Syrian refugees to neighbouring countries, with more than one million refugees currently registered by UNHCR in Lebanon. While some are living in tented settlements, the majority are living in strained conditions in rented accommodation or collective shelters in the Bekaa Valley next to Syria. Adolescents are particularly vulnerable in any crisis. In 2013-4, the American University in Beirut in collaboration with the Women's Refugee Commission, Johns Hopkins and Save the Children, sought to understand the specific experiences of very young adolescents, those 10-14 years of age, in this protracted crisis context. Methods: The study was conducted in 2014 in Barelias and Qabelias - two urban areas located close to each other in the Beka'a valley that has a large concentration of Syrian refugees. Focus group discussions (FGDs), including community mapping and photo elicitation, were conducted with 10-12 and 13-14 year old Syrian refugee adolescents, in order to obtain information about their experiences and perspectives. FGDs were also implemented with 15-16 year old Syrian refugees and separately also with adult refugees, to consider their perspectives on the needs and risks of these adolescents. Results: A total of 16 FGD (8 for each sex, with 6-9 participants in each) were conducted in Arabic across the two sites, with 59 female participants and 59 male participants. The experiences and risks faced by these adolescents were significantly impacted by economic strain and loss of educational opportunities during displacement, and only a minority of adolescents in the study reported attending school. Additionally, on-going protection risks for girls were felt to be higher due to the crisis and displacement. In Lebanon this has resulted in increased risks of child marriage and limitations in mobility for adolescent girls. Adolescents, themselves expressed tensions with their Lebanese counterparts and feared verbal attacks and beatings from school-aged Lebanese male youth. Conclusions: Families and adolescents have been dramatically affected by the conflict in Syria, and the resulting forced displacement. The loss of educational opportunities is perhaps the most significant effect, with long-term devastating outcomes. Additionally, the futures of Syrian girls are deeply affected by new protection concerns, particularly as they are exposed to an unfamiliar and more liberal society in Lebanon. Child marriage and limitations in their mobility - particularly for girls - are presented by families as coping strategies to these risks. Programming is needed to ensure sustained education access for all adolescents, and to educate very young adolescents and their parents on managing their own health and well-being, given the multiple strains. More effort is needed to encourage positive interaction between adolescent Lebanese and adolescent Syrian refugees. PMID- 29167699 TI - A qualitative study exploring child marriage practices among Syrian conflict affected populations in Lebanon. AB - Background: Recent reports have suggested that child marriage among Syrians may be increasing as a result of displacement and conflict. This study sought to gather qualitative data about the factors that promote child marriage practices among Syrian refugees in Al Marj area in the Bekaa valley, Lebanon, where the majority of Syrian refugees have settled in Lebanon. The second aim of this study was to generate recommendations on how to mitigate the drivers and consequences of child marriage practices based on the findings. Methods: Eight focus group discussions were conducted separately with married and unmarried young women and mothers and fathers of married and unmarried women. Furthermore, researchers conducted 11 key informant interviews with service providers and stakeholders to understand how conflict and displacement influenced marriage practices of Syrian refugees in Al Marj community. Results: Although child marriage was a common practice in pre-conflict Syria, new factors seem to contribute to a higher risk of child marriage among Syrian refugees in Lebanon. Respondents cited conflict- and displacement-related safety issues and feeling of insecurity, the worsening of economic conditions, and disrupted education for adolescent women as driving factors. Service providers, young women, and parents also reported changes in some marriage practices, including a shorter engagement period, lower bride price, change in cousin marriage practices, and a reduced age at marriage. Conclusions: Recommendations for interventions to mitigate the drivers of child marriage and its negative consequences should be built on a clear understanding of the local refugee context and the drivers of child marriage in refugee settings. Interventions should involve multiple stakeholders, they should be adjusted to target each specific context, age group and marital status. For these interventions to be effective, they should be addressed concurrently, and they should be delivered in a culturally sensitive and practical manner. PMID- 29167698 TI - Transitions into puberty and access to sexual and reproductive health information in two humanitarian settings: a cross-sectional survey of very young adolescents from Somalia and Myanmar. AB - Background: Very young adolescents (VYA) in humanitarian settings are largely neglected in terms of sexual and reproductive health (SRH). This study describes the characteristics of VYA aged 10-14 years in two humanitarian settings, focusing on transitions into puberty and access to SRH information. Methods: Data were collected through a cross-sectional survey with Somali VYA residing in the Kobe refugee camp in Ethiopia (N = 406) and VYA from Myanmar residing in the Mae Sot and Phop Phra migrant communities in Thailand (N = 399). The average age was 12 years (about half were girls) in both communities. Participants were recruited using multi-stage cluster-based sampling with probability proportional to size in each site. Descriptive statistics were used to describe the sociodemographic, family, peer, and schooling characteristics and to explore transitions into puberty and access to SRH information. Results: Most VYA in both sites reported living with both parents; nine in ten reported feeling that their parents/guardians care about them, and over half said that their parents/guardians monitor how and with whom they spend their free time. High proportions in both sites were currently enrolled in school (91.4% Somali, 87.0% from Myanmar). Few VYA, particularly those aged 10-12, reported starting puberty, although one in four Somali indicated not knowing whether they did so. Most girls from Myanmar who had started menstruating reported access to menstrual hygiene supplies (water, sanitation, cloths/pads). No Somali girls reported access to all these supplies. While over half of respondents in both sites reported learning about body changes, less than 20% had learnt about pregnancy and the majority (87.4% Somali, 78.6% from Myanmar) indicated a need for more information about body changes. Parents/guardians were the most common source of SRH information in both sites, however VYA indicated that they would like more information from friends, siblings, teachers and health workers. Conclusions: This study highlights gaps in SRH information necessary for healthy transitions through puberty and supplies for menstrual hygiene in two humanitarian settings. VYA in these settings expressed closeness to their parents/guardians and the majority were in school. Introducing early SRH interventions that involve parents and educational centers may thus yield promising results, providing VYA with the necessary skills for understanding and dealing with their pubertal and sexual development.

AB - Background: Nepal is representative of Low and Middle Income Countries (LMIC) with limited availability of mental health services in rural areas, in which the majority of the population resides. Methods: This formative qualitative study explores resources, challenges, and potential barriers to the development and implementation of evidence-based Comprehensive Community-based Mental Health Services (CCMHS) in accordance with the mental health Gap Action Programme (mhGAP) for persons with severe mental health disorders and epilepsy. Focus Group Discussions (FGDs, n = 9) and Key-Informant Interviews (KIIs, n = 26) were conducted in a rural district in western Nepal. Qualitative data were coded using the Framework Analysis Method employing QSR NVIVO software. Results: Health workers, general community members, and persons living with mental illness typically attributed mental illness to witchcraft, curses, and punishment for sinful acts. Persons with mental illness are often physically bound or locked in structures near their homes. Mental health services in medical settings are not available. Traditional healers are often the first treatment of choice. Primary care workers are limited both by lack of knowledge about mental illness and the inability to prescribe psychotropic medication. Health workers supported upgrading their existing knowledge and skills through mhGAP resources. Health workers lacked familiarity with basic computing and mobile technology, but they supported the introduction of mobile technology for delivering effective mental health services. Persons with mental illness and their family members supported the development of patient support groups for collective organization and advocacy. Stakeholders also supported development of focal community resource persons to aid in mental health service delivery and education. Conclusion: Health workers, persons living with mental illness and their families, and other stakeholders identified current gaps and barriers related to mental health services. However, respondents were generally supportive in developing community based care in rural Nepal. PMID- 29167701 TI - Xylose induces cellulase production in Thermoascus aurantiacus. AB - Background: Lignocellulosic biomass is an important resource for renewable production of biofuels and bioproducts. Enzymes that deconstruct this biomass are critical for the viability of biomass-based biofuel production processes. Current commercial enzyme mixtures have limited thermotolerance. Thermophilic fungi may provide enzyme mixtures with greater thermal stability leading to more robust processes. Understanding the induction of biomass-deconstructing enzymes in thermophilic fungi will provide the foundation for strategies to construct hyper production strains. Results: Induction of cellulases using xylan was demonstrated during cultivation of the thermophilic fungus Thermoascus aurantiacus. Simulated fed-batch conditions with xylose induced comparable levels of cellulases. These fed-batch conditions were adapted to produce enzymes in 2 and 19 L bioreactors using xylose and xylose-rich hydrolysate from dilute acid pretreatment of corn stover. Enzymes from T. aurantiacus that were produced in the xylose-fed bioreactor demonstrated comparable performance in the saccharification of deacetylated, dilute acid-pretreated corn stover when compared to a commercial enzyme mixture at 50 degrees C. The T. aurantiacus enzymes retained this activity at of 60 degrees C while the commercial enzyme mixture was largely inactivated. Conclusions: Xylose induces both cellulase and xylanase production in T. aurantiacus and was used to produce enzymes at up to the 19 L bioreactor scale. The demonstration of induction by xylose-rich hydrolysate and saccharification of deacetylated, dilute acid-pretreated corn stover suggests a scenario to couple biomass pretreatment with onsite enzyme production in a biorefinery. This work further demonstrates the potential for T. aurantiacus as a thermophilic platform for cellulase development. PMID- 29167703 TI - Spin-wave propagation in cubic anisotropy materials. AB - The information carrier of modern technologies is the electron charge whose transport inevitably generates Joule heating. Spin-waves, the collective precessional motion of electron spins, do not involve moving charges and thus avoid Joule heating [1-3]. In this respect, magnonic devices in which the information is carried by spin-waves attract interest for low-power computing. However implementation of magnonic devices for practical use suffers from low spin-wave signal and on/off ratio. Here we demonstrate that cubic anisotropy materials can enhance spin-wave signals by improving spin-wave amplitude as well as group velocity and attenuation length. Furthermore, cubic anisotropy material shows an enhanced on/off ratio through a laterally localized edge mode, which closely mimics the gate-controlled conducting channel in traditional field-effect transistors. These attractive features of cubic anisotropy materials will invigorate magnonics research towards wave-based functional devices.

AB - Background: The enzymes for efficient hydrolysis of lignocellulosic biomass are a major factor in the development of an economically feasible cellulose bioconversion process. Up to now, low hydrolysis efficiency and high production cost of cellulases remain the significant hurdles in this process. The aim of the present study was to develop a versatile cellulase system with the enhanced hydrolytic efficiency and the ability to synthesize powerful inducers by genetically engineering Trichoderma reesei. Results: In our study, we employed a systematic genetic strategy to construct the carbon catabolite-derepressed strain T. reesei SCB18 to produce the cellulase complex that exhibited a strong cellulolytic capacity for biomass saccharification and an extraordinary high beta glucosidase (BGL) activity for cellulase-inducing disaccharides synthesis. We first identified the hypercellulolytic and uracil auxotrophic strain T. reesei SP4 as carbon catabolite repressed, and then deleted the carbon catabolite repressor gene cre1 in the genome. We found that the deletion of cre1 with the selectable marker pyrG led to a 72.6% increase in total cellulase activity, but a slight reduction in saccharification efficiency. To facilitate the following genetic modification, the marker pyrG was successfully removed by homologous recombination based on resistance to 5-FOA. Furthermore, the Aspergillus niger BGLA-encoding gene bglA was overexpressed, and the generated strain T. reesei SCB18 exhibited a 29.8% increase in total cellulase activity and a 51.3-fold enhancement in BGL activity (up to 103.9 IU/mL). We observed that the cellulase system of SCB18 showed significantly higher saccharification efficiency toward differently pretreated corncob residues than the control strains SDC11 and SP4. Moreover, the crude enzyme preparation from SCB18 with high BGL activity possessed strong transglycosylation ability to synthesize beta-disaccharides from glucose. The transglycosylation product was finally utilized as the inducer for cellulase production, which provided a 63.0% increase in total cellulase activity compared to the frequently used soluble inducer, lactose. Conclusions: In summary, we constructed a versatile cellulase system in T. reesei for efficient biomass saccharification and powerful cellulase inducer synthesis by combinational genetic manipulation of three distinct types of genes to achieve the customized cellulase production, thus providing a viable strategy for further strain improvement to reduce the cost of biomass-based biofuel production.

AB - Cyanobacterial mats are laminated microbial ecosystems which occur in highly diverse environments and which may provide a possible model for early life on Earth. Their ability to produce hydrogen also makes them of interest from a biotechnological and bioenergy perspective. Samples of an intertidal microbial mat from the Elkhorn Slough estuary in Monterey Bay, California, were transplanted to a greenhouse at NASA Ames Research Center to study a 24-h diel cycle, in the presence or absence of molybdate (which inhibits biohydrogen consumption by sulfate reducers). Here, we present metagenomic analyses of four samples that will be used as references for future metatranscriptomic analyses of this diel time series. PMID- 29167705 TI - Comparative analysis of impacted upper canines: Panoramic radiograph Vs Cone Beam Computed Tomography. AB - Background: The use of CBCT exam in the study of IMC is not new. However, it's still not known in what specific aspects CBCT exam shows a better result than then conventional exams. The aim of this study was to compare and conclude in what way the opinion regarding upper canine impaction differed when observing a panoramic image compared to the observation of a set of CBCT reconstructions. Material and Methods: Twenty patients (10 males and 10 females) with a total of 28 impacted maxillary canines were identified from the database of the Department of Dentistry, Faculty of Medicine, University of Coimbra. For each canine, two different images were available: a panoramic image and a set of CBCT reconstructions. After a random distribution of both groups images, nine orthodontists completed a questionnaire where they were asked to evaluate ten different questions regarding canine impaction. Statistic analysis was performed using Cronbach's alpha statistics, Kappa statistics and McNemar test, considering p<0,05 statistically significant. Results: This study showed differences between the two images regarding tooth position. A statistical significant poor agreement was found between the two methods for the mesio-distal position of the apex (k=0,388, p<0,001) and for the labio-palatal tip cusp position (k=0,035, p=0,114). The adjacent root resorption showed a poor and very poor agreement between the two methods. Every other items were scored with an agreement between modalities ranging from moderate to strong. Conclusions: The analyses of panoramic images versus CBCT images reconstructions provided different information regarding tooth position (especially concerning the mesio-distal apex position and the labio-palatal cusp position) but also in the assessment of root resorption. Further investigation should be done to determine in what cases CBCT exam has a clear advantage over conventional 2D exams, justifying its use.

PMID- 29167706 TI - The effect of oxalate-based desensitizers on the microleakage and shear bond strength of resin modified glass ionomer. AB - Background: The first line of intervention to alleviate tooth sensitivity is to use dentin desensitizers such as oxalate-based desensitizers. When the dentin sensitivity continues even after application of desensitizers the next intervention would be restoration of the lesion. The aim of this in vitro study was to investigate the effect of prior application of oxalate-based desensitizer on the marginal microleakage and shear bond strength of resin modified glass ionomer (RMGI) restorations. Material and Methods: In order to prepare the specimens for microleakage test standard class v cavities were prepared on buccal surfaces of 45 teeth. The specimens were randomly divided into three equal groups. In control group, the cavities were restored with RMGI. In group 2, oxalate-based desensitizer was applied and the specimens were kept in distilled water for 14 days before restoration. In group 3 the specimens were prepared similar to group 2 and the surface of the cavities were slightly cut with bur before restoration. Methyleneblue penetration was evaluated using stereomicroscope. The data were analyzed using non-parametric tests. For shear bond strength test cervical dentin specimens were prepared and were divided into 3 groups. Surface treatments were similar to microleakage test. RMGI was packed into cylindrical plastic molds which were placed on the cut surface of the tooth and light cured. The data were analyzed by one-way ANOVA. Results: There was not any significant difference in dye penetration in dentin margins among the groups, but microleakage in enamel margins of group 2 and 3 was higher than group 1. There was no significant difference in shear bond strength among the groups (p =0.285). Conclusions: Non carious cervical lesions which were treated for hypersensitivity with oxalate-based desensitizers could be restored with resin modified glass ionomer if the hypersensitivity persists. Key words:Dentin hypersensitivity, oxalate-based desensitizers, microleakage, shear bond strength. PMID- 29167707 TI - Solubility and pH of bioceramic root canal sealers: A comparative study. AB - Background: This study compared the solubility and the pH of different root canal sealers in vitro. Material and Methods: BioRootTMRCS, TotalFill BC Sealer, MTA Fillapex, SealapexTM, AH Plus, EasySeal, Pulp Canal SealerTM and N2 were tested. Similar specimens were prepared using ring molds with an internal diameter of 20 +/- 0,1 mm and a height of 1,5 +/- 0,1 mm and digitally weighted to register the mass of each specimen before and after immersion in distilled water. Solubility was determined after 24 hours and statistically analysed using a one-way ANOVA test and post-hoc Tukey test. The pH value was measured by a digital pH meter after 3 and 24 hours from manipulation. Results: BioRootTMRCS and TotalFill BC Sealer showed significantly higher solubility (P<0.05). All the remnant root canal sealers fulfilled the requirements of solubility of the International Standard Organization 6876 demonstrating a weight loss of less than 3%. BioRootTMRCS and Totalfill BC Sealer exhibited high alkaline pH over time (P<0.05); the alkalinity of the other tested cements was significantly lower. Conclusions: The prolonged alkalinity of bioceramic sealer matched the increase in solubility. This may encourage their biological and antimicrobial effects, but the ongoing solubility may impact their ability to prevent apical leakage. Key words:pH, root canal sealers, solubility.

AB - Background: Tooth abnormalities are most often present in individuals with oral clefts than general population, and lead to a long-term impact on facial anatomy and self-esteem. The purpose of this study was to compare the proportion of dental anomalies between the cleft side and non-cleft side in individuals with non-syndromic unilateral alveolar clefts (AC). Material and Methods: Twenty cone beam computed tomography (CBCT) scans were converted into three-dimensional (3D) virtual models. The dental anomalies considered were: tooth agenesis; supernumerary teeth; giroversion; and microdontia. Statistical analysis was performed using the McNemar's test and Fisher's exact test (p<0.05). Results: Statistically significant differences were not found either between the prevalence of individuals with dental abnormalities on the non-cleft side and the sides of the AC (p = 1.00), or sex (p = 0.36). Tooth agenesis was the most prevalent dental anomaly (55.6%). On the cleft side the lateral incisor was tooth most involved by dental anomalies; and the second premolar was the most affected on the non-cleft side. Conclusions: This study showed a high frequency of dental anomalies in the cleft individuals and indicated that the side of AC and sex do not interfere in the proportion of dental anomalies on non-cleft side.

AB - Background: Historically, the prevalence of dental caries was higher in urban areas than rural areas of Thailand. This study aim to examine the time trends in caries status in children in Thailand. Material and Methods: Linear regression was used to examine trend of dental caries prevalence and mean number of teeth with caries, filled and missing due to caries (dmft/DMFT) in urban and rural, of 3-, 5-6 and 12-year olds from seven Thailand National Oral Health Surveys conducted approximately every 5 years from 1977 to 2012. Results: There were declines in the caries prevalence and mean dmft/DMFT in every age group. Significant results were observed in the mean dmft of 3 year-olds and the mean DMFT of 12 year-olds (p= 0.03 and p=0.05, respectively). A significant trend of declining prevalence of dental caries was observed in urban children ages 5-6 (p=0.002), along with urban 12 year-olds (p<0.001). A declining trend of mean dmft for 3 and 5-6 year-olds, and mean DMFT for 12 year-olds was observed in both rural and urban areas, but significant results were shown in urban 3 and 5-6 year olds (P=0.04, and p<0.001, respectively), and urban 12 year-olds (p=0.001). For restoration outcome, both urban and rural of all age groups have an increasing trend of mean ft/FT index. Conclusions: There have been differences over time in the prevalence and quantity of dental caries between urban and rural school children. A significant reduction was observed in urban areas. More effort needs to be given to supply rural areas in order to have fair and equal access of all citizens to oral health care.

Histometric analysis. AB - Background: The nicotine may generate a influence on bone repair and longevity of dental implants. This fact makes studies to improve the surface of the implants are constantly conducted. This study aimed to evaluate the influence of subcutaneous nicotine injection in the osseointegration process on different implant surfaces, through histomorphometric analysis. Material and Methods: Therefore, twenty-two male rabbits were randomly distributed into two groups according to the subcutaneous injections: (1) nicotine, 3 mg/day/kg and (2) 0.9% NaCI, 3 mL/day/kg, three times a day. Subgroups were then designated - machined and anodized dental implants were installed in the right and left tibia bones, respectively. The animals were subjected to euthanasia after periods of eight weeks for histomorphometric analysis. The bone samples with implants were removed and the routine histological processing was performed. Next, the images obtained from the blades were evaluated by the Image ToolTM software, assessing the osseointegrated areas of implants (BIC), in pixels. Data obtained were subjected to intergroup statistical analysis through the Kruskal-Wallis non-parametric test (alpha=5%). Results: The test result showed no statistically significant difference among the groups studied (p=0.446). Conclusions: Based on the methodology studied, it is concluded that the daily application of low doses of nicotine did not interfere with the osseointegration of machined and anodized implants. Key words:Bone-implant interface, implants, osseointegration.

AB - Background: The purpose of this study was to determine the influence of linear and rotational pre-cure bracket displacement during the bonding procedure on shear bond strength (SBS) of orthodontic brackets. Material and Methods: Stainless steel orthodontic premolar brackets were bonded to the buccal surfaces of 50 human pre-molars with a conventional two-step bonding protocol. Extracted human pre-molars were divided into 5 groups (n=10/group). In the Control Group, the brackets were bonded with no pre-cure bracket displacement or rotation. The Rotation Group was bonded with 45 degrees of pre-cure rotation. The Displacement Group was bonded with 2mm pre-cure linear displacement. The Rotation-Displacement Group was bonded with pre-cure movements of 45o counter-clockwise rotation and 2mm displacement. The Slippage Group was bonded with 2mm each of mesial and distal pre-cure linear displacement. Photo-activation was carried out on the lateral sides of the bracket. Shear debonding force was measured, 24 hours after initial bonding, with an Instron universal testing machine using a knife-edged chisel. Data was analyzed using one-way ANOVA test. Adhesive Remnant Index (ARI) was scored under 15x magnification. The ARI data was analyzed using the Chi square test (p -value < 0.05). Results: No statistically significant differences were detected among the control and experimental groups (p = 0.331). The rotation and displacement group showed the highest mean SBS than all other groups. Mean SBS for all groups were above the clinically acceptable range. No statistically significant differences were detected in ARI scores among groups (p = 0.071). Conclusions: Linear and rotational pre-cure bracket displacements do not appear to effect the shear bond strength of orthodontic brackets.

PMID- 29167712 TI - Vertical Root Fracture initiation in curved roots after root canal preparation: A dentinal micro-crack analysis with LED transillumination. AB - Background: One of the causative factors of root defects is the increased friction produced by rotary instrumentation. A high canal curvature may increase stress, making the tooth more susceptible to dentinal cracks. The purpose of this study was to evaluate dentinal micro-crack formation with the ProTaper NEXT and ProTaper Universal systems using LED transillumination, and to analyze the micro crack generated at the point of maximum canal curvature. Material and Methods: 60 human mandibular premolars with curvatures between 30-49 degrees and radii between 2-4 mm were used. The root canals were instrumented using the Protaper Universal(r) and Protaper NEXT(r) systems, with the aid of the Proglider(r) system. The obtained samples were sectioned transversely before subsequent analysis with LED transillumination at 2 mm and 8 mm from the apex and at the point of maximum canal curvature. Defects were scored: 0 for no defects; and 1 for micro-cracks. Results: Root defects were not observed in the control group. The ProTaper NEXT system caused fewer defects (16.7%) than the ProTaper Universal system (40%) (P<0.05). The ProTaper Universal system caused significantly more micro-cracks at the point of maximum canal curvature than the ProTaper NEXT system (P<0.05). Conclusions: Rotary instrumentation systems often generate root defects, but the ProTaper NEXT system generated fewer dentinal defects than the ProTaper Universal system. A higher prevalence of defects was found at the point of maximum curvature in the ProTaper Universal group.

PMID- 29167713 TI - The effect of social geographic factors on the untreated tooth decay among head start children. AB - Background: Disparities among untreated dental caries exist for children from low income families in the United States. Understanding of the mechanism of the disparities is required to reduce it and social geographic factors are one of the important influences. Although the effect of fluoridated water has been well reported, studies of other sociogeograpic factors, such as the density of available dentists, are still very limited. The objective of this study is to explore the effect of sociogeographic factors on the number of primary teeth with untreated dental caries among children from low-income families who are enrolled in Head Start programs throughout Northeast Ohio of the United States. Material and Methods: This was a cross-sectional chart review study. Three hundred-eighty eight charts were reviewed, and the number of primary teeth with untreated dental caries (dt) and the children's addresses were retrieved. The sociogeographic variables, including fluoridated water availability and the density of available dentists who accept a government-supported insurance (Medicaid dentists), were collected. Results: The mean (standard deviation) of children's age was 3.51 (1.14) years with a range of 7 months to 5 years. A negative binomial regression model analysis, which used dt as a dependent variable and children's characteristic factors (i.e. age, gender, insurance type, and total number of primary teeth) and sociogeographic factors (i.e. Population, total number of Medicaid dentists, density of Medicaid dentist, and Fluoride water availability) of cities, as independent variables, demonstrated that only the density of Medicaid dentist in the sociogeographic factors indicated a significant effect (Estimated beta-Coefficients (Standard Errors)=-0.003 (0.002), p=0.030). Conclusions: This study demonstrated a significant negative association between the density of available dentists and untreated dental caries among children from low-income families in Head Start programs in Northeast Ohio. Increasing available dentists may be a strategy to reduce the number of early childhood caries. Key words:Child, poverty, dental caries, Health Services Accessibility. PMID- 29167714 TI - Micro-CT study of the root canal anatomy of maxillary canines. AB - Background: This study aimed to describe the anatomy of maxillary canines from a Western Mexican sub-population using micro-computed tomography (micro-CT). Material and Methods: Maxillary canines (n=32) were scanned at 19.6um voxel resolution. Number and location of canals, the distance between the cemento enamel junction and apex, occurrence of accessory and lateral canals, presence of oval canals, number of foraminas as well as two- (area, perimeter, roundness, aspect ratio, major and minor diameters) and three-dimensional (volume, surface area, and SMI) analysis were performed. Data of two-dimensional analyses at 5 different apical levels was statistically compared using Kruskal-Wallis tests (alpha=0.05). Results: Overall, 31 specimens had one root with a main canal (Vertucci type I). Mean distance from the apex to the cemento-enamel junction was 16.32+/-2.27. Apical foraminas were present in 14 specimens (43.75%). No statistical differences were found in the two-dimensional analyses between the foramen and the 1 and 2mm apical levels (P >0.05). Conclusions: Maxillary canines presenting one root canal were present in a high percentage of cases (96%). The prevalence of long oval canals was <12% at the apical third and at least 37% of the sample showed more than one point of exit in the last apical 3mm.

AB - Background: Presence of voids at root canal wall-apical seal material interface gives rise to the entrapment of toxins and microorganisms, which might have a relationship with post treatment disease. The present study was carried out to evaluate the effect of different mixing (manual and ultrasonic) and placement (manual and manual in association with indirect ultrasonic) methods of Calcium enriched Mixture (CEM) cement on the number and dimensions of voids in the apical plug in simulated apexification models. Material and Methods: A total of 80 human maxillary central incisors with mature apices were selected. After simulation of the open apices, the teeth were divided into 4 groups (n=20) based on the mixing and placement techniques of CEM cement: group 1, manual mixing-manual placement; group 2, manual mixing-manual placement in association with indirect ultrasonic technique; group 3, ultrasonic mixing-manual placement; and group 4, ultrasonic mixing-manual placement in association with indirect ultrasonic technique. The samples were placed within gypsum sockets in which the periodontal ligament was reconstructed with polyether impression material. After placement the apical plugs, a wet piece of cotton was placed on canal orifices, followed by dressing with Cavit. The samples were incubated at 37 degrees C and 100% relative humidity for 7 days. Then the voids between the material and root canal walls were counted with the CBCT technique. The void dimensions were scored with the following scoring system: score 1, no voids; score 2, the void size less than half of the size of the evaluated cross-section; score 3, the void size larger than half of the size of the evaluated cross-section. Statistical analyses were carried out with chi-squared and Fisher's exact tests. Statistical significance was defined at P<0.05. Results: The maximum (7) and minimum (2) number of voids were detected in groups 1 and 2, respectively. The difference between these two groups was statistically significant (p<0.05). The differences in the number of voids between groups with similar mixing technique and different mixing techniques (i.e. groups 1 and 3 and groups 2 and 4) were not significant (p>0.05). Void dimensions in all the study groups were in score 2 category and no score 3 was recorded in the study groups. Conclusions: Under the limitations of the present study, manual placement in association with indirect ultrasonic technique was a proper technique to improve the quality of apical plug, considering the decrease in the number of voids.

AB - Background: A considerable number of gastrointestinal disorders (GIDs) of varied nature (inflammatory, infectious, genetic and other etiology) may produce alterations in the hard and soft oral tissues. Among these are Crohn's disease, ulcerative colitis, celiac and gastroesophageal reflux disease. Material and Methods: Article search was done using the National library of medicine (PubMed) database using different search terms and analyzed according to their importance. Results: A large variety of GIDs can give rise to oral lesions, including: RAS like ulceration, mucosal tags, cobblestoning, mucogingivitis, labial and facial swelling, pyostomatitis vegetans, disgeusia and dental abnormalities, among others. Although in most cases the gastrointestinal signs and symptoms highlight in the clinical picture, a considerable percentage of these patients are affected by oral manifestations before the onset of gastrointestinal symptoms. This lesions can cause significant functional and aesthetics damages as well deteriorate the patient quality of life. Conclusions: Although the frequency of oral manifestations is variable across GIDs and in most cases is non-specific, these alterations may precede the underlying disease and therefore can facilitate an opportune diagnosis.

PMID- 29167718 TI - Preparation Prerequisites for Effective Irrigation of Apical Root Canal: A Critical Review. AB - Background: It is well recognized that disinfection of the complex root canal system at the apical root canal remains the most critical therapeutic measure to treat apical periodontitis. Material and Methods: Observational and experimental data in relation to the anatomy of the apical root canal in different tooth types and the cross sectional diameters of the apical part of the most commonly used hand and rotary files are critically reviewed. Results: The present data analysis confirm that the challenging issue of antibacterial efficacy of modern preparation protocols in non-surgical endodontics requires more attention to apical root canal irrigation as a balance between safety and effectiveness. Ex vivo investigations clearly indicate that a specific design of the chemo mechanical preparation is needed at the onset of RCT, more particularly in infected teeth. Design should be based on specific anatomical parameters, and must determine the appropriate size and taper of preparation as pre-requirements for effective and safe apical irrigation. Conclusions: The optimal irrigation protocols might be designed on the basis of technical specifications of the preparations procedures, such as the penetration depth, the type of the needle, the required time for continuous irrigant flow, the concentration of NaOCl, and the activation parameters.

A systematic review. AB - Background: Khat (Catha edulis) chewing is a highly prevalent habit in the Arabian Peninsula and East Africa, and has recently spread to Western countries. The association between khat chewing and oral mucosal lesions is well documented in the literature. However, there is no concrete evidence on the association between khat chewing and periodontal disease. The purpose of this systematic review was to analyze the influence of khat chewing on periodontal health. Material and Methods: A literature search of PubMed, Scopus and Web of Sciences databases was carried out to identify relevant articles published from 1990 to May 2017. The inclusion criteria were all clinical studies that assessed the relationship between khat chewing and periodontal disease. Results: The search yielded 122 articles, of which 10 were included in this systematic review. Most of the studies exhibited a positive correlation between khat chewing and periodontal disease. Conclusions: Altogether, the analysis of the current evidence reveals that khat chewing is destructive to the periodontium and enhances the risk of periodontal disease progression. However, due to variability of studies, more longitudinal case-controlled studies are highly warranted to establish a causal relation between khat chewing and periodontal disease. Key words:Khat chewing, periodontal health, periodontal disease, risk factor. PMID- 29167720 TI - Peek polymer in orthodontics: A pilot study on children. AB - The purpose of the study has been making the orthodontic space maintainers in PEEK polymer (Polyetheretherketone) through a digital workflow. New digital technologies are taking hold in diagnosis, therapy and in dental laboratories. The digital world can help dentist in diagnosis and therapy: -diagnosis through the acquisition of radiographic images (CBCT) or scanners which allow the creation of 3D digital models - about therapy thanks to dental CAD CAM system. It consists of design devices through an dedicated software CAD and then realize devices through CAM system. We used digital system to improve the quality of the treatment and reduce costs. Peek polymer, subject of studies in recent years, thanking to its characteristics, resulted useful for this study. According to a nine month- follow up the devices were found comfortable, satisfying, personalized and minimally visible for the patients. These devices were found suitable to maintain the space. About material, thanks to its dimensional stability, mechanical strength but specially, thanks to its biocompatibility, PEEK was found as a very good material to build space maintainers. The workflow allowed a simulation of the treatment plan with a better collaboration and acceptance of the patient. Digital system reduced the systematic mistakes during the various phases and the production time. The digital system saved space creating a virtual plaster casts collection. Key words:PEEK, CAD/CAM system, space maintainers, orthodontic prevention. PMID- 29167721 TI - Clinical and radiographic features of pycnodysostosis: A case report. AB - Pycnodysostosis is a rare disorder that was first described in 1962; however, it was only in 1996 that the defective gene was discovered, which led to a better understanding of this disease. This study reports and discuss a case of pycnodysostosis. In addition, a search of articles published in PubMed-Medline was performed. The case was a 13-year-old girl who was referred to a private clinic for dental treatment. Clinical examination showed midface hypoplasia, prominent cheeks, a high nasal bridge, beaked nose, spoon-shaped fingers, frontal bossing, open fontanelles and dental alterations, findings compatible with pycnodysostosis. Patients with this disease also suffer from fractures because of bone hardness with almost no elasticity, a fact that requires special care particularly in the case of children and adolescents. The diagnosis of pycnodysostosis is made based on clinical and radiographic findings. Clinicians should be aware of this disorder to provide adequate dental treatment. Key words:Pycnodysostosis, developmental bone disease, imaging diagnosis. PMID- 29167723 TI - The Impact of Audio Book on the Elderly Mental Health. AB - Introduction: The growing elderly population calls mental health professionals to take measures concerning the treatment of the elderly mental disorders. Today in developed countries, bibliotherapy is used for the treatment of the most prevalent psychiatric disorders. Therefore, this study aimed to investigate the effects of audio book on the elderly mental health of Retirement Center of Shahid Beheshti University of Medical Sciences. Methods: This experimental study was conducted on 60 elderly people participated in 8 audio book presentation sessions, and their mental health aspects were evaluated through mental health questionnaire (SCL-90-R). Data were analyzed using SPSS 24. Results: Data analysis revealed that the mean difference of pretest and posttest of control group is less than 5.0, so no significant difference was observed in their mental health, but this difference was significant in the experimental group (more than 5.0). Therefore, a significant improvement in mental health and its dimensions have observed in elderly people participated in audio book sessions. This therapeutic intervention was effective on mental health dimensions of paranoid ideation, psychosis, phobia, aggression, depression, interpersonal sensitivity, anxiety, obsessive-compulsive and somatic complaints. Conclusion: Considering the fact that our population is moving toward aging, the obtained results could be useful for policy makers and health and social planners to improve the health status of the elderly.

AB - Asperger syndrome (AS) is a subtype of Autism Spectrum Disorder (ASD) characterized by major problems in social and nonverbal communication, together with limited and repetitive forms of behavior and interests. The linguistic and cognitive development in AS is preserved which help us to differentiate it from other subtypes of ASD. However, significant effects of AS on cognitive abilities and brain functions still need to be researched. Although a clear cut pathology for Asperger has not been identified yet, recent studies have largely focused on brain imaging techniques to investigate AS. In this regard, we carried out a systematic review on behavioral, cognitive, and neural markers (specifically using MRI and fMRI) studies on AS. In this paper, behavior, motor skills and language capabilities of individuals with Asperger are compared to those in healthy controls. In addition, common findings across MRI and fMRI based studies associated with behavior and cognitive disabilities are highlighted.

AB - Introduction: Graph theoretical analysis of functional Magnetic Resonance Imaging (fMRI) data has provided new measures of mapping human brain in vivo. Of all methods to measure the functional connectivity between regions, Linear Correlation (LC) calculation of activity time series of the brain regions as a linear measure is considered the most ubiquitous one. The strength of the dependence obligatory for graph construction and analysis is consistently underestimated by LC, because not all the bivariate distributions, but only the marginals are Gaussian. In a number of studies, Mutual Information (MI) has been employed, as a similarity measure between each two time series of the brain regions, a pure nonlinear measure. Owing to the complex fractal organization of the brain indicating self-similarity, more information on the brain can be revealed by fMRI Fractal Dimension (FD) analysis. Methods: In the present paper, Box-Counting Fractal Dimension (BCFD) is introduced for graph theoretical analysis of fMRI data in 17 methamphetamine drug users and 18 normal controls. Then, BCFD performance was evaluated compared to those of LC and MI methods. Moreover, the global topological graph properties of the brain networks inclusive of global efficiency, clustering coefficient and characteristic path length in addict subjects were investigated too. Results: Compared to normal subjects by using statistical tests (P<0.05), topological graph properties were postulated to be disrupted significantly during the resting-state fMRI. Conclusion: Based on the results, analyzing the graph topological properties (representing the brain networks) based on BCFD is a more reliable method than LC and MI.

AB - Introduction: The nerve fibers in central nervous system are surrounded by myelin sheet which is formed by oligodendrocytes. Cell therapy based on oligodendrocytes and their precursors transplantation can hold a promising alternative treatment for myelin sheet repair in demyelinating diseases. Methods: Human Dental Pulp Stem Cells (hDPSCs) are noninvasive, autologous and easy available source with multipotency characteristics, so they are in focus of interest in regenerative medicine. In the present study, hDPSCs were differentiated into oligoprogenitor using glial induction media, containing Retinoic Acid (RA), basic Fibroblast Growth Factor (bFGF), Platelet-Derived Growth Factor (PDGF), N2 and B27. The differentiated Oligoprogenitor Cells (OPCs) were evaluated for nestin, Olig2, NG2 and O4 using immunocytochemistry. Also, the expression of nestin, Olig2 and PDGFR alpha gens (neuroprogenitor and oligoprogenitor markers) were investigated via RT PCR technique. Results: The results indicate that glial differentiation medium induces the generation of oligoprogenitor cells as revealed via exhibition of specific glial markers, including Olig2, NG2 and O4. The expersion of nestin gene (neuroprogenitor marker) and Olig2 and PDGFR-alpha genes (oligoprogentor markers) were detected in treated hDPSCs at the end of the induction stage. Conclusion: hDPSCs can be induced to transdifferentiate into oligoprogenitor cells and respond to the routinely applied regents for glial differentiation of mesanchymal stem cells. These data suggest the hDPSCs as a valuable source for cell therapy in neurodegenerative diseases.

AB - Introduction: Previous studies have shown that seizure can induce cognitive impairment. On the other hand, soy phytoestrogens, which are mainly found in soybean (Glycine max (L.) Merr.), have beneficial effects on the nervous system. However, little is known about their probable effects on seizure. The present study aimed to examine the probable effects of soy extract, containing the phytoestrogen genistein on seizure-induced cognitive and synaptic plasticity impairment in Ovariectomized (OVX) rats. Methods: Rats were ovariectomized, implanted with guide cannula and then divided into 5 groups (n=7-8 in each group): PBS, KA, Saline-KA, Higher Dose Soy (HDS-KA), and Lower Dose Soy (LDS-KA) groups. Animals of the HDS-KA and LDS-KA groups received intraperitoneal administration of soy extract (20 and 2 mg/kg, respectively) and the Saline-KA group received normal saline once a day for 4 days. Sixty minutes after the last injection, Kainic Acid (KA) or PBS was injected into the left lateral ventricle via pre-implanted guide cannula to induce generalized seizures. The Morris water maze task and in vivo field potential recordings were conducted 7 days later. Results: Soy extract at both doses significantly improved learning impairment and at the higher dose (20 mg/kg) significantly prevented seizure-induced spatial memory impairment and deficit of long-term potentiation in the hippocampus. Conclusion: The soy extract containing the phytoestrogen genistein may have beneficial effects on memory deficit induced by seizure in OVX rats and this effect is accompanied by a beneficial effect on synaptic plasticity. PMID- 29167727 TI - The Effect of Repetitive Transcranial Magnetic Stimulation on Postural Stability After Acute Stroke: A Clinical Trial. AB - Introduction: Balance impairment is a common problem and a major cause of motor disability after stroke. Therefore, this study aimed to investigate whether low frequency repetitive Transcranial Magnetic Stimulation (rTMS) improves the postural balance problems in stroke patients. Methods: This randomized double blind clinical trial with 12 weeks follow-up was conducted on stroke patients. Treatment was carried with 1 Hz rTMS in contralateral brain hemisphere over the primary motor area for 20 minutes (1200 pulses) for 5 consecutive days. Static postural stability, Medical Research Council (MRC), Berg Balance Scale (BBS), and Fugl-Meyer assessments were evaluated immediately, 3 weeks and 12 weeks after intervention. Results: A total of 26 patients were enrolled (age range=53 to 79 years; 61.5% were male) in this study. Administering rTMS produced a significant recovery based on BBS (df=86, 7; F=7.4; P=0.01), Fugl-Meyer Scale (df=86, 7; F=8.7; P<0.001), MRC score (df=87, 7; F=2.9; P=0.01), and static postural stability (df=87, 7; F=9.8; P<0.001) during the 12 weeks follow-up. Conclusion: According to the findings, rTMS as an adjuvant therapy may improve the static postural stability, falling risk, coordination, motor recovery, and muscle strength in patients with stroke. PMID- 29167728 TI - Predicting the Risk of Hearing Impairment Following the Cervical Spine Diseases by Measuring the Cervical Range of Movements: A Pilot Study. AB - Introduction: Cervical spine abnormalities can affect the ear vessels and or nerves with different mechanisms. Ear dysfunctions following cervical spine injuries can be manifested as hearing loss, vertigo, or tinnitus. Usually, cervical spine injuries can cause pain and Range of Motion (ROM) limitation. The major objective of this study was to determine which cervical ROM limitation was accompanied with higher level of hearing loss. Methods: In this cross-sectional study, 42 volunteers (20 women and 22 men) with cervical spine injury and pain participated after giving their informed consent. Audiometry, tympanometry, and pure-tone threshold of individuals were taken in frequencies from 250 to 8000 Hz in all cases. The ROM limitation in flexion, extension and rotation was recorded. Results: About 53% of participants had bilateral hearing loss. In 40.48% (n=17) of cases, rotation to the left was limited. Flexion and extension motion were restricted on 23.8% (n=10) and 30.95% (n=13) of the participants, respectively. There was no statistically significant relationship between sex and hearing loss but a significant correlation was observed between hearing loss and ROM limitation of rotation to the left in men. Conclusion: According to the present study, the likelihood of hearing loss was high in patients with cervical left rotation limitation, and that the incidence of hearing loss following the cervical spine injuries was more in men. It seems that left Rotation limitation can be used as a predictor to diagnosis of hearing impairment following the cervical spine injuries (especially in men). PMID- 29167730 TI - ON THE BLOCK-SPARSITY OF MULTIPLE-MEASUREMENT VECTORS. AB - Based on the compressive sensing (CS) theory, it is possible to recover signals, which are either compressible or sparse under some suitable basis, via a small number of non-adaptive linear measurements. In this paper, we investigate recovering of block-sparse signals via multiple measurement vectors (MMVs) in the presence of noise. In this case, we consider one of the existing algorithms which provides a satisfactory estimate in terms of minimum mean-squared error but a non sparse solution. Here, the algorithm is first modified to result in sparse solutions. Then, further modification is performed to account for the unknown block sparsity structure in the solution, as well. The performance of the proposed algorithm is demonstrated by experimental simulations and comparisons with some other algorithms for the sparse recovery problem.

AB - Introduction: Children with attention-deficit/hyperactivity disorder (ADHD) have some impairment in emotional relationship which can be due to problems in emotional processing. The present study investigated neural correlates of early stages of emotional face processing in this group compared with typically developing children using the Gamma Band Activity (GBA). Methods: A total of 19 children diagnosed with ADHD (Combined type) based on DSM-IV classification were compared with 19 typically developing children matched on age, gender, and IQ. The participants performed an emotional face recognition while their brain activities were recorded using an event-related oscillation procedure. Results: The results indicated that ADHD children compared to normal group showed a significant reduction in the gamma band activity, which is thought to reflect early perceptual emotion discrimination for happy and angry emotions (P<0.05). Conclusion: The present study supports the notion that individuals with ADHD have some impairments in early stage of emotion processing which can cause their misinterpretation of emotional faces. PMID- 29167731 TI - Purification and characterization of GAD65-specific monoclonal autoantibodies. AB - Autoantibodies against antigens expressed by insulin-producing beta cells are circulating in both healthy individuals and patients at risk of developing Type 1 diabetes. Recent studies suggest that another set of antibodies (anti-idiotypic antibodies) exists in this antibody/antigen interacting network to regulate auto reactive responses. Anti-idiotypic antibodies may block the antigen-binding site of autoantibodies or inhibit autoantibody expression and secretion. The equilibrium between autoantibodies and anti-idiotypic antibodies plays a critical role in mediating or preventing autoimmunity. Herein, using GAD65/anti-GAD65 autoantibodies as a model system, we aimed at establishing reliable approaches for purification of highly pure autoantibodies for the downstream investigation of molecular mechanisms underlying such a network. PMID- 29167732 TI - Blockchain protocols in clinical trials: Transparency and traceability of consent. AB - Clinical trial consent for protocols and their revisions should be transparent for patients and traceable for stakeholders. Our goal is to implement a process allowing the collection of patients' informed consent, which is bound to protocol revisions, storing and tracking the consent in a secure, unfalsifiable and publicly verifiable way, and enabling the sharing of this information in real time. For that, we will built a consent workflow using a rising technology called Blockchain. This is a distributed technology that brings a built-in layer of transparency and traceability. Additionally, it removes the need for third parties, and gives participative control to the peer-to-peer users. From a more general and prospective point of view, we believe Blockchain technology brings a paradigmatical shift to the entire clinical research field. We designed a Proof of-Concept protocol consisting of time-stamping each step of the patient's consent collection using Blockchain; thus archiving and historicising the consent through cryptographic validation in a securely unfalsifiable and transparent way. For each revision of the protocol, consent was sought again. We obtained a single document, in a standard open format, that accounted for the whole consent collection process: timestamped consent status with regards to each version of the protocol. This document cannot be corrupted, and can be checked on any dedicated public website. It should be considered as a robust proof of data. In the future, we think that the complex data flow of a clinical trial can be tracked using Blockchain. Moreover, a blockchain core functionality, named Smart Contract, can help prevent clinical trial events not to happen in the right chronological order: including patients before they consented or analysing case report forms data before freezing the database. This will help reaching reliability, security, and transparency, and could be a consistent step towards reproducibility. PMID- 29167733 TI - A 4-week, lifestyle-integrated, home-based exercise training programme elicits improvements in physical function and lean mass in older men and women: a pilot study. AB - BACKGROUND: Developing alternative exercise programmes that can alleviate certain barriers to exercise such as psychological, environmental or socio-economical barriers, but provide similar physiological benefits e.g. increases in muscle mass and strength, is of grave importance. This pilot study aimed to assess the efficacy of an unsupervised, 4-week, whole-body home-based exercise training (HBET) programme, incorporated into daily living activities, on skeletal muscle mass, power and strength. METHODS: Twelve healthy older volunteers (63+/-3 years, 7 men: 5 women, BMI: 29+/-1 kg/m2) carried out the 4-week "lifestyle-integrated" HBET of 8 exercises, 3x12 repetitions each, every day. Before and after HBET, a number of physical function tests were carried out: unilateral leg extension 1-RM (one- repetition maximum), MVC (maximal voluntary contraction) leg extension, lower leg muscle power (via Nottingham Power Rig), handgrip strength and SPPBT (short physical performance battery test). A D 3-Creatine method was used for assessment of whole-body skeletal muscle mass, and ultrasound was used to measure the quadriceps cross-sectional area (CSA) and vastus lateralis muscle thickness. RESULTS: Four weeks HBET elicited significant (p<0.05) improvements in leg muscle power (276.7+/-38.5 vs. 323.4+/-43.4 W), maximal voluntary contraction (60 degrees : 154.2+/-18.4 vs. 168.8+/-15.2 Nm, 90 degrees : 152.1+/-10.5 vs. 159.1+/ 11.4 Nm) and quadriceps CSA (57.5+/-5.4 vs. 59.0+/-5.3 cm 2), with a trend for an increase in leg strength (1-RM: 45.7+/-5.9 vs. 49.6+/-6.0 kg, P=0.08). This was despite there being no significant differences in whole-body skeletal muscle mass, as assessed via D 3-Creatine. CONCLUSIONS: This study demonstrates that increases in multiple aspects of muscle function can be achieved in older adults with just 4-weeks of "lifestyle-integrated" HBET, with a cost-effective means. This training mode may prove to be a beneficial alternative for maintaining and/or improving muscle mass and function in older adults. PMID- 29167734 TI - Treatment of chronic telogen effluvium with oral minoxidil: A retrospective study. AB - Background: Chronic telogen effluvium (CTE) may be primary or secondary to various causes, including drug reaction, nutritional deficiency and female pattern hair loss (FPHL). Oral minoxidil stimulates hair growth, and topical minoxidil is used in the treatment of FPHL and male androgenetic alopecia. minoxidil has not been used to treat CTE. This study aimed to assess the treatment of CTE with once daily oral minoxidil. Methods: Women with a diagnosis of CTE based on >6 month history of increased telogen hair shedding, no visible mid frontal scalp hair loss (Sinclair stage 1) and no hair follicle miniaturization on scalp biopsy were treated with once daily oral minoxidil. Hair shedding scores (HSS) at baseline, 6 and 12 months were analysed using the Wilcoxon rank sum test for pair-wise comparisons. Results: Thirty-six women were treated with oral minoxidil (range, 0.25-2.5 mg) daily for 6 months. Mean age was 46.9 years (range 20-83), HSS at baseline was 5.64, and duration of diagnosis was 6.55 years (range 1-27). There was a reduction in mean HSS scores from baseline to 6 months of 1.7 (p<0.001) and baseline to 12 months of 2.58 (p<0.001). Five women who described trichodynia at baseline, noted improvement or resolution within 3 months. Mean change in blood pressure was minus 0.5 mmHg systolic and plus 2.1 mmHg diastolic. Two patients developed transient postural dizziness that resolved with continued treatment. One patient developed ankle oedema. Thirteen women developed facial hypertrichosis. For 6 patients this was mild and did not require treatment; 4 had waxing of their upper lip or forehead; 3 had laser hair removal. No patients developed any haematological abnormality. All 36 women completed 12 months of treatment. Conclusions: Once daily oral minoxidil appears to reduce hair shedding in CTE. Placebo controlled studies are recommended to further assess this response. PMID- 29167735 TI - A review of data sharing statements in observational studies published in the BMJ: A cross-sectional study. AB - In order to understand the current state of data sharing in observational research studies, we reviewed data sharing statements of observational studies published in a general medical journal, the British Medical Journal. We found that the majority (63%) of observational studies published between 2015 and 2017 included a statement that implied that data used in the study could not be shared. If the findings of our exploratory study are confirmed, room for improvement in the sharing of real-world or observational research data exists. PMID- 29167736 TI - On the interpretability and computational reliability of frequency-domain Granger causality. AB - This Correspondence article is a comment which directly relates to the paper "A study of problems encountered in Granger causality analysis from a neuroscience perspective" ( Stokes and Purdon, 2017). We agree that interpretation issues of Granger causality (GC) in neuroscience exist, partially due to the historically unfortunate use of the name "causality", as described in previous literature. On the other hand, we think that Stokes and Purdon use a formulation of GC which is outdated (albeit still used) and do not fully account for the potential of the different frequency-domain versions of GC; in doing so, their paper dismisses GC measures based on a suboptimal use of them. Furthermore, since data from simulated systems are used, the pitfalls that are found with the used formulation are intended to be general, and not limited to neuroscience. It would be a pity if this paper, even if written in good faith, became a wildcard against all possible applications of GC, regardless of the large body of work recently published which aims to address faults in methodology and interpretation. In order to provide a balanced view, we replicate the simulations of Stokes and Purdon, using an updated GC implementation and exploiting the combination of spectral and causal information, showing that in this way the pitfalls are mitigated or directly solved. PMID- 29167737 TI - Make researchers revisit past publications to improve reproducibility. AB - Scientific irreproducibility is a major issue that has recently increased attention from publishers, authors, funders and other players in the scientific arena. Published literature suggests that 50-80% of all science performed is irreproducible. While various solutions to this problem have been proposed, none of them are quick and/or cheap. Here, we propose one way of reducing scientific irreproducibility by asking authors to revisit their previous publications and provide a commentary after five years. We believe that this measure will alert authors not to over sell their results and will help with better planning and execution of their experiments. We invite scientific journals to adapt this proposal immediately as a prerequisite for publishing. PMID- 29167738 TI - Updated mtCOI reference dataset for the Bemisia tabaci species complex. AB - Members of the whitefly Bemisia tabaci species complex cause millions of dollars of damage globally and are considered one of the world's most invasive species. They are capable of causing extensive damage to major vegetable, grain legume and fiber crops. All member of the species complex are morphologically identical therefore, data from the partial mitochondrial cytochrome oxidase subunit I (mtCOI) gene sequence has been used to identify the various species. The current reference dataset that is widely used is found on the CSIRO data portal. However, the reference set stored on the CSIRO data does not include newly added sequences (2013-2017), therefore an updated reference dataset is needed. All mtCOI data for the Bemisia tabaci species complex were downloaded on 22 May 2017 from GenBank and after quality checking, a dataset of 1,071 unique sequences and 696 base pairs was generated (https://doi.org/10.6084/m9.figshare.5437420.v1). PMID- 29167739 TI - Measuring evolutionary rates of proteins in a structural context. AB - We describe how to measure site-specific rates of evolution in protein-coding genes and how to correlate these rates with structural features of the expressed protein, such as relative solvent accessibility, secondary structure, or weighted contact number. We present two alternative approaches to rate calculations, one based on relative amino-acid rates and the other based on site-specific codon rates measured as dN/dS. In addition to describing the specific analysis protocols we recommend, we also provide a code repository containing scripts to facilitate these kinds of analyses. PMID- 29167740 TI - Prenatal maternal plasma DNA screening for cystic fibrosis: A computer modelling study of screening performance. AB - Background: Prenatal cystic fibrosis (CF) screening is currently based on determining the carrier status of both parents. We propose a new method based only on the analysis of DNA in maternal plasma. Methods: The method relies on the quantitative amplification of the CF gene to determine the percentage of DNA fragments in maternal plasma at targeted CF mutation sites that carry a CF mutation. Computer modelling was carried out to estimate the distributions of these percentages in pregnancies with and without a fetus affected with CF. This was done according to the number of DNA fragments counted and fetal fraction, using the 23 CF mutations recommended by the American College of Medical Genetics for parental carrier testing. Results: The estimated detection rate (sensitivity) is 70% (100% of those detected using the 23 mutations), the false-positive rate 0.002%, and the odds of being affected given a positive screening result 14:1, compared with 70%, 0.12%, and 1:3, respectively, with current prenatal screening based on parental carrier testing. Conclusions: Compared with current screening practice based on parental carrier testing, the proposed method would substantially reduce the number of invasive diagnostic procedures (amniocentesis or chorionic villus sampling) without reducing the CF detection rate. The expected advantages of the proposed method justify carrying out the necessary test development for use in a clinical validation study. PMID- 29167742 TI - The effect of natural sounds on the anxiety of patients undergoing coronary artery bypass graft surgery. AB - Background: This study aims to investigate the effect of natural sounds on the anxiety of patients undergoing coronary artery bypass graft surgery (CABG). Methods: In this clinical trial, 90 patients, who were candidates for CABG in an urban area of Iran, were selected and randomly assigned to intervention and control groups by the minimization method. In the intervention group, natural sounds were broadcast through headphones for 30 min. In the control group, headphones connected to a silent device were used. The research instruments were a demographic questionnaire and the Spielberger State-Trait Anxiety Inventory (STAI). These were used before the intervention, 30 min after the music, and before the surgery in the waiting room for both groups. Data was analyzed using SPSS software. Results: The mean anxiety level of the intervention group has been found to be significantly lower than that of the control group half an hour after the intervention as well as in the waiting room in the preoperative period (p = 0.001). Moreover, the mean anxiety of the intervention group decreases, while it increases for the control group over time (p < 0.001). Conclusion: Natural sounds can be used as a non-pharmacological way to reduce the anxiety of patients undergoing CABG. Trial registration: IRCT2017011723190N3, Registered 1 March 2017. PMID- 29167741 TI - Experimental autoimmune encephalomyelitis from a tissue energy perspective. AB - Increasing evidence suggests a key role for tissue energy failure in the pathophysiology of multiple sclerosis (MS). Studies in experimental autoimmune encephalomyelitis (EAE), a commonly used model of MS, have been instrumental in illuminating the mechanisms that may be involved in compromising energy production. In this article, we review recent advances in EAE research focussing on factors that conspire to impair tissue energy metabolism, such as tissue hypoxia, mitochondrial dysfunction, production of reactive oxygen/nitrogen species, and sodium dysregulation, which are directly affected by energy insufficiency, and promote cellular damage. A greater understanding of how inflammation affects tissue energy balance may lead to novel and effective therapeutic strategies that ultimately will benefit not only people affected by MS but also people affected by the wide range of other neurological disorders in which neuroinflammation plays an important role. PMID- 29167743 TI - Prevalence and characteristics of ST131 clone among unselected clinical Escherichia coli in a Chinese university hospital. AB - Background: Escherichia coli clinical sequence type 131 (ST131) has emerged as an extensively antimicrobial resistant E. coli clonal group in recent years throughout the world. The aim of this study was to investigate the prevalence and molecular characteristics of ST131 among unselected E. coli clinical isolates in a Chinese university hospital. Methods: Seven hundred consecutive E. coli isolates were collected at a Chinese university hospital between 2014 and 2015. Isolates belonging to ST131 were identified by PCR and multilocus sequence typing (MLST), and then characterized for antibiotic resistance, CTX-M-type extended spectrum beta-lactamase genes, fluoroquinolone resistance genes, O types, phylogenetic groups, virulence factors and PFGE patterns. Results: Overall, 83 (11.6%) isolates were identified as ST131 group. The H30 lineage accounted for 53 (63.9%) of the ST131 isolates, including 13 H30-Rx and 40 H30 non-Rx. The remaining 30 isolates belonged to H41 lineage. Two O types were identified in this study: O25b (66.3%) and O16 (33.7%). Compared with O25b-B2-ST131 isolates, O16-B2-ST131 isolates harbored less virulence factors of adhesins. ST131 H30 Rx isolates had significantly higher virulence score than those of other isolates. O16-B2-ST131 isolates were shown to have a lower resistance to quinolones than O25b-B2-ST131 isolates. 5 nonsynonymous mutations (GyrA S83 L, D87N, ParC S80I, E84V and ParE I529L) were strongly associated with ST131 H30 and O25b isolates. Results of PFGE demonstrated that these isolates were classified into 68 pulsotypes and these subtypes were grouped into 23 different PFGE clusters using 70% similarity cut-off value. Conclusions: This is the first study to reveal the prevalence and molecular characteristic of ST131 clonal group among consecutive clinical E. coli isolates in China. Our findings demonstrated that ST131 lineage accounts for a small proportion of clinical E. coli isolates in China, which included two major groups: O25b-B2-ST131 and O16-B2-ST131. Our results implies that O16-B2-ST131 subclone may be an important type of E. coli ST 131 in China, which suggests that future studies should not ignore such clone in this country. PMID- 29167744 TI - Feasibility of an incentive scheme to promote active travel to school: a pilot cluster randomised trial. AB - Background: In Great Britain, 19% of trips to primary school within 1 mile, and 62% within 1-2 miles, are by car. Active travel to school (ATS) offers a potential source of moderate-to-vigorous physical activity (MVPA). This study tested the feasibility of an intervention to promote ATS in 9-10 year olds and associated trial procedures. Methods: A parallel cluster randomised pilot trial was conducted over 9 weeks in two schools from a low-income area in northeast England. Measures included daily parental ATS reports (optionally by SMS) and child ATS reports, as well as accelerometry (ActiGraph GT3X+). At baseline, all children were asked to wear the accelerometer for the same week; in the post randomisation phase, small subsamples were monitored each week. In the 2 weeks when a child wore the accelerometer, parents also reported the start and finish times of the journey to school. The intervention consisted of a lottery-based incentive scheme; every ATS day reported by the parent, whether by paper or SMS, corresponded to one ticket entered into a weekly L5 voucher draw. Before each draw session, the researcher prepared the tickets and placed them into an opaque bag, from which one was randomly picked by the teacher at the draw session. Results: Four schools replied positively (3.3%, N = 123) and 29 participants were recruited in the two schools selected (33.0%, N = 88). Participant retention was 93.1%. Most materials were returned on time: accelerometers (81.9%), parental reports (82.1%) and child reports (97.9%). Draw sessions lasted on average 15.9 min (IQR 10-20) and overall session attendance was 94.5%. Parent-child report agreement regarding ATS was moderate (k = 0.53, CI 95% 0.45; 0.60). Differences in minutes of accelerometer-assessed MVPA between parent-reported ATS and non-ATS trips were assessed during two timeframes: during the journey to school based on the times reported by the parent (U = 390.5, p < 0.05, 2.46 (n = 99) vs 0.76 (n = 13)) and in the hour before classes (U = 665.5, p < 0.05, 4.99 (n = 104) vs 2.55 (n = 19)). Differences in MVPA minutes between child-reported ATS and non-ATS trips were also significant for each of the timeframes considered (U = 596.5, p < 0.05, 2.40 (n = 128) vs 0.81 (n = 15) and U = 955.0, p < 0.05, 4.99 (n = 146) vs 2.59 (n = 20), respectively). Conclusions: Data suggest the feasibility of an ATS incentive scheme and of most trial procedures. School recruitment stood out as requiring further piloting.

AB - Background: Both obesity and congenital heart disease (CHD) are risk factors for the long-term cardiovascular health of children and adolescents. The addition of smart mobile technology to conventional lifestyle counseling for weight management offers great potential to appeal to technologically literate youth and can address a large geographical area with minimal burden to participants. This pilot study seeks to examine the influence of a 1-year lifestyle intervention on nutrition and physical activity-related health outcomes in overweight or obese children and adolescents with CHD. Methods: This is a pilot and feasibility study which utilizes a single-arm, prospective design with a goal to recruit 40 overweight and obese patients. The feasibility metrics will evaluate the integrity of the study protocol, data collection and questionnaires, recruitment and consent, and acceptability of the intervention protocol and primary outcome measures. The primary clinical outcome metrics are anthropometry, body composition, and cardiorespiratory exercise capacity. The secondary clinical metrics include quality of life, nutrition and physical activity behavior, lung and muscle function, and cardio-metabolic risk factors. Outcomes are assessed at baseline, 6 months, and 1 year. To date, a total of 36 children and youth (11 girls), aged 7-17 years (mean = 14.4 years), have commenced the intervention. Recruitment for the study was initiated in June 2012 and is currently ongoing. Discussion: The information provided in this paper is intended to help researchers and health professionals with the development and evaluation of similar lifestyle intervention programs. Since the application of smartphones to pediatric cardiac health and obesity management is a novel approach, and continued research in this area is warranted, this paper may serve as a foundation for further exploration of this health frontier and inform the development of a broader strategy for obesity management in pediatric cardiology. Trial registration: This pilot study was retrospectively registered at the www.ClinicalTrials.gov registry as NCT02980393 in November 2016, with the study commencing in May 2012.

AB - Background: During pulmonary artery catheter (PAC) implantation, inaccurate measurements of hemodynamic parameters due to infection or thrombosis of PAC can result in severe complications. Method: In order to develop a new PAC material, we evaluated the antibacterial and antithrombotic activities of the two types of PAC (Swan Ganz catheter and prototype catheter) in 14 pigs. Results: In the 3-day group, bacterial infection rate was not different between the two types of PAC. In the 7-day group, bacterial infection rate of the prototype catheter was twice as elevated as that of the Swan-Ganz catheter. In the 3-day group, thrombus formation rate of the prototype catheter was twice as elevated as that of the Swan-Ganz catheter. In the 7-day group, thrombus formation rate was the same for the two types of PAC. Conclusion: Here, we report an experimental pig model that confirms differences in antibacterial and antithrombotic activities.

AB - Chronic 1% metformin treatment is nephrotoxic in mice, but this dose may nonetheless confer health benefits if given intermittently rather than continuously. Here, we examined the effects of 1% metformin given every-other week (EOW) or two consecutive weeks per month (2WM) on survival of 2-year-old male mice fed standard chow. EOW and 2WM mice had comparable life span compared with control mice. A significant reduction in body weight within the first few weeks of metformin treatment was observed without impact on food consumption and energy expenditure. Moreover, there were differences in the action of metformin on metabolic markers between the EOW and 2WM groups, with EOW metformin conferring greater benefits. Age-associated kidney lesions became more pronounced with metformin, although without pathological consequences. In the liver, metformin treatment led to an overall reduction in steatosis and was accompanied by distinct transcriptomic and metabolomic signatures in response to EOW versus 2WM regimens. Thus, the absence of adverse outcomes associated with chronic, intermittent use of 1% metformin in old mice has clinical translatability into the biology of aging in humans. PMID- 29167750 TI - Dysregulation of the miR-146a-Smad4 axis impairs osteogenesis of bone mesenchymal stem cells under inflammation. AB - Osteoporosis is a common disease that affects patient quality of life, especially among the elderly population. Although inflammation contributes significantly to osteoporosis, the underlying mechanism is unclear. In this study, we found that tumor necrosis factor (TNF)-alpha, an inflammatory environment mimic, inhibits osteogenesis of bone mesenchymal stem cells (BMSCs), induces miR-146a and decreases Smad4. Moreover, overexpression of miR-146a inhibited the osteogenic ability of BMSCs, whereas blocking miR-146a partially rescued the osteogenesis deficiency under TNF-alpha treatment. Molecularly, miR-146a decreased Smad4 expression at the protein level by binding to an element located in the Smad4 3' untranslated region, and restoration of Smad4 reversed the inhibitory effects of miR-146a on osteogenesis. Together, our results showed that the inflammatory environment mimic TNF-alpha inhibits osteogenesis via upregulation of miR-146a and subsequent downregulation of Smad4, thus suggesting that therapeutic manipulation of miR-146a maybe a potential strategy to improve osteogenesis in the context of osteoporosis. PMID- 29167751 TI - Diffusion Tensor Imaging in an Infant Undergoing Functional Hemispherectomy: A Surgical Aid. AB - Hemispherectomy is a highly effective treatment option for children with severe, unilateral, medically refractory epilepsy. Many patients undergoing hemispherectomy are younger patients with dysmorphic brains, making accomplishing a complete disconnection challenging due to anatomic distortion, even with the aid of intraoperative navigation. Diffusion tensor imaging (DTI) has been proposed as a valuable imaging adjunct perioperatively to help guide surgeons intraoperatively, as well as for post-surgical evaluation and confirmation of complete hemispheric disconnection. We present a case of an infant with Otoharra syndrome and hemimegencephaly who underwent a functional hemispherectomy for treatment of severe, refractory seizures. We demonstrate how DTI was utilized both pre-, intra-, and postoperatively to help plan, guide, and confirm surgical disconnection. The application of exquisite DTI for this child led to her being seizure-free, which is a life-changing event with long-lasting benefits and will become even more critical as we now perform these disconnection procedures with a more minimally invasive approach.

AB - Rift Valley fever (RVF) is a mosquito-borne zoonotic disease endemic to Africa which affects both ruminants and humans. RVF causes serious damage to the livestock industry and is also a threat to public health. The Rift Valley fever virus has a segmented negative-stranded RNA genome consisting of Large (L)-, Medium (M)-, and Small (S)-segments. The live-attenuated MP-12 vaccine is immunogenic in livestock and humans, and is conditionally licensed for veterinary use in the U.S. The MP-12 strain encodes 23 mutations (nine amino acid substitutions) and is attenuated through a combination of mutations in the L-, M , and S-segments. Among them, the M-U795C, M-A3564G, and L-G3104A mutations contribute to viral attenuation through the L- and M-segments. The M-U795C, M A3564G, L-U533C, and L-G3750A mutations are also independently responsible for temperature-sensitive (ts) phenotype. We hypothesized that a serial passage of the MP-12 vaccine in culture cells causes reversions of the MP-12 genome. The MP 12 vaccine and recombinant rMP12-DeltaNSs16/198 were serially passaged 25 times. Droplet digital PCR analysis revealed that the reversion occurred at L-G3750A during passages of MP-12 in Vero or MRC-5 cells. The reversion also occurred at M A3564G and L-U533C of rMP12-DeltaNSs16/198 in Vero cells. Reversion mutations were not found in MP-12 or the variant, rMP12-TOSNSs, in the brains of mice with encephalitis. This study characterized genetic stability of the MP-12 vaccine and the potential risk of reversion mutation at the L-G3750A ts mutation after excessive viral passages in culture cells. PMID- 29167752 TI - A Prospective Study of Distal Metatarsal Chevron Osteotomies with K-Wire Fixations to Treat Hallux Valgus Deformities. AB - Introduction Hallux valgus is one of the most common forefoot deformities worldwide. Females are affected more often than males. The three most common clinical symptoms are the painful bunion, transfer metatarsalgia, and hammer or claw toes. Methods This case series consisted of 20 patients who had chevron osteotomy from January 2015 to January 2016. The clinical assessment was measured by The American Orthopedic Foot and Ankle Score (AOFAS), and radiologic assessment was determined by preoperative and postoperative hallux valgus angle (HVA) and intermetatarsal angle (IMA). Results The patients' mean age was 56 years. Out of 20 patients, 19 were female, and one was male. The mean AOFAS improved from 51 preoperatively to 82 postoperatively. The HVA improved from 26 degrees preoperatively to 14 degrees . There were five complications including four Kirschner (K)-wire complications. Conclusion Distal chevron osteotomy is a reliable and time-tested procedure. The K-wire fixation has a relatively high complication rate. We planned to use other methods of fixation and then compared them with K-wires fixation results for future studies. PMID- 29167754 TI - A mass that has no (EBUS) echo. AB - We report findings for a patient that underwent endobronchial ultrasound (EBUS) guided transbronchial needle aspiration (TBNA) for diagnostic purposes after an abnormal chest CT. The patient initially presented with cough and shortness of breath. Chest CT revealed a 6 cm soft tissue mass with mildly enlarged right hilar lymph nodes (LNs) and a small right sided pleural effusion. Based on these radiologic findings, the patient underwent an EBUS guided FNA of the mass. To our surprise, the mass was hypoechoic by EBUS and on aspiration, the syringe filled with yellow fluid. This finding in combination with a re-review of the CT scans with a special focus on the Hounsfield Units of the lesion confirmed the diagnosis of a mediastinal bronchogenic cyst. This case demonstrates the role of Hounsfield units in analyzing mediastinal masses and highlights the effectiveness of EBUS guided TBNA in diagnosis and treatment of bronchogenic cysts. PMID- 29167753 TI - Homology Modeling of Human Concentrative Nucleoside Transporters (hCNTs) and Validation by Virtual Screening and Experimental Testing to Identify Novel hCNT1 Inhibitors. AB - Objective: The nucleoside transporter family is an emerging target for cancer, viral and cardiovascular diseases. Due to the difficulty in the expression, isolation and crystallization of membrane proteins, there is a lack of structural information on any of the mammalian and for that matter the human proteins. Thus the objective of this study was to build homology models for the three cloned concentrative nucleoside transporters hCNT1, hCNT2 and hCNT3 and validate them for screening towards the discovery of much needed inhibitors and probes. Methods: The recently reported crystal structure of the Vibrio cholerae concentrative nucleoside transporter (vcCNT), has satisfactory similarity to the human CNT orthologues and was thus used as a template to build homology models of all three hCNTs. The Schrodinger modeling suite was used for the exercise. External validation of the homology models was carried out by docking a set of recently reported known hCNT1 nucleoside class inhibitors at the putative binding site using induced fit docking (IDF) methodology with the Glide docking program. Then, the hCNT1 homology model was subsequently used to conduct a virtual screening of a 360,000 compound library, and 172 compounds were obtained and biologically evaluated for hCNT 1, 2 and 3 inhibitory potency and selectivity. Results: Good quality homology models were obtained for all three hCNTs as indicated by interrogation for various structural parameters and also external validated by docking of known inhibitors. The IDF docking results showed good correlations between IDF scores and inhibitory activities; particularly for hCNT1. From the top 0.1% of compounds ranked by virtual screening with the hCNT1 homology model, 172 compounds selected and tested for against hCNT1, hCNT2 and hCNT3, yielded 14 new inhibitors (hits) of (i.e., 8% success rate). The most active compound exhibited an IC50 of 9.05 MUM, which shows a greater than 25-fold higher potency than phlorizin the standard CNT inhibitor (IC50 of 250 MUM). Conclusion: We successfully undertook homology modeling and validation for all human concentrative nucleoside transporters (hCNT 1, 2 and 3). The proof-of concept that these models are promising for virtual screening to identify potent and selective inhibitors was also obtained using the hCNT1 model. Thus we identified a novel potent hCNT1 inhibitor that is more potent and more selective than the standard inhibitor phlorizin. The other hCNT1 hits also mostly exhibited selectivity. These homology models should be useful for virtual screening to identify novel hCNT inhibitors, as well as for optimization of hCNT inhibitors. PMID- 29167755 TI - Infrared thermography of welding zones produced by polymer extrusion additive manufacturing. AB - In common thermoplastic additive manufacturing (AM) processes, a solid polymer filament is melted, extruded though a rastering nozzle, welded onto neighboring layers and solidified. The temperature of the polymer at each of these stages is the key parameter governing these non-equilibrium processes, but due to its strong spatial and temporal variations, it is difficult to measure accurately. Here we utilize infrared (IR) imaging - in conjunction with necessary reflection corrections and calibration procedures - to measure these temperature profiles of a model polymer during 3D printing. From the temperature profiles of the printed layer (road) and sublayers, the temporal profile of the crucially important weld temperatures can be obtained. Under typical printing conditions, the weld temperature decreases at a rate of approximately 100 degrees C/s and remains above the glass transition temperature for approximately 1 s. These measurement methods are a first step in the development of strategies to control and model the printing processes and in the ability to develop models that correlate critical part strength with material and processing parameters. PMID- 29167756 TI - An innovative approach for serial injection in marginal vein and blood collection from auricular artery in New Zealand white Rabbit. AB - Serial injection into marginal vein and blood collection through auricular artery in New Zealand white Rabbit (Oryctolagus cuniculus) is an important procedure for various types of experimental studies. Limitations of the existing methods for serial injection and blood collection includes complex procedures, causes considerable discomfort to rabbits, whole blood samples obtained are highly prone to hemolysis and lastly detailed protocol is not available in the literature. Approximately 10 min before commencement of the experiment, a local anesthetic cream was applied over the right and left ear lobes. The skin at the site of sample collection and injection was prepared by shaving the area on both ears and wiping it with alcohol swab. Once prepared, a 26 GA (BD Neoflon) intravenous cannula was inserted into the marginal vein of the ear and secured with an adhesive plaster. In the other ear, a 24 GA (BD Neoflon) intravenous cannula was placed in the auricular/central artery and secured with an adhesive plaster. The novel and refined method described here has been standardized and found to be reliable. The samples obtained using this method is not susceptible to hemolysis and hence we recommend this method for serial injection and blood collection in rabbits. *Easy to perform*Not prone to hemolysis*Detailed methodology described. PMID- 29167758 TI - High-throughput microarray for antimicrobial susceptibility testing. AB - We describe the development of a novel, high-throughput, nano-scale microarray platform for antimicrobial susceptibility testing (AST). The platform allows to process 480 samples at 50 nL volume on a single chip, analyze by fluorescence read-out with an easy dunk-and-rinse step, and the ability to process multiple samples and chips simultaneously. We demonstrate the applicability of this chip for culturing community acquired methicillin resistant Staphylococcus aureus (CA MRSA), and perform AST against clinical isolates of CA-MRSA. The chip platform holds promise for an impact in microbial biotechnology as an attractive high throughput, lower sample volume and quicker alternative to conventional AST such as the traditional broth microdilution or the newer automated systems.

AB - Model-driven systems engineering has been more fascinating process for the microbial production of biofuel and bio-refineries in chemical and pharmaceutical industries. Genome-scale modeling and simulations have been guided for metabolic engineering of Clostridium species for the production of organic solvents and organic acids. Among them, Clostridium sticklandii is one of the potential organisms to be exploited as a microbial cell factory for biofuel production. It is a hyper-ammonia producing bacterium and is able to catabolize amino acids as important carbon and energy sources via Stickland reactions and the development of the specific pathways. Current genomic and metabolic aspects of this bacterium are comprehensively reviewed herein, which provided information for learning about protein catabolism-directed biofuel production. It has a metabolic potential to drive energy and direct solventogenesis as well as acidogenesis from protein catabolism. It produces by-products such as ethanol, acetate, n-butanol, n-butyrate and hydrogen from amino acid catabolism. Model-driven systems engineering of this organism would improve the performance of the industrial sectors and enhance the industrial economy by using protein-based waste in environment-friendly ways. PMID- 29167759 TI - Study on bioremediation of Lead by exopolysaccharide producing metallophilic bacterium isolated from extreme habitat. AB - Lead released from manufacturing factories, recycling plants, automobile company and landfill leachate is abundantly found in wastewater. An efficient bioremediating agent for lead removal from wastewater is expected to ease the ever increasing problem. The present study reports Pseudomonas sp. W6 isolated from extreme habitat of hot water spring of North-East India evaluated for its Lead biosorption property. The bacterium showed capacity to resist 1.0 mM lead in both solid and liquid minimal media. Epifluorescence microscopy reveal the viability of bacterial cells under metal stress condition. ICP-MS analysis revealed 65% and 61.2% removal of lead from the Synthetic Bangladesh Ground Water medium in batch culture and column study respectively which was higher when compared to biosorption capacity of P. aeruginosa MTCC2474, P. alcaligenes MJ7 from forest soil and P. ficuserectae PKRS11 from uranium rich soil. Exopolysaccharide released by the isolate which influenced biosorption revealed the presence of ligands assayed using microbial hydrophobicity and FTIR. The extremophilic isolate is proposed as a choice for efficient bioremediation of lead contaminated wastewater.

AB - Thyroid ultrasound (US) is a key examination for the management of thyroid nodules. Thyroid US is easily accessible, noninvasive, and cost-effective, and is a mandatory step in the workup of thyroid nodules. The main disadvantage of the method is that it is operator dependent. Thyroid US assessment of the risk of malignancy is crucial in patients with nodules, in order to select those who should have a fine needle aspiration (FNA) biopsy performed. Due to the pivotal role of thyroid US in the management of patients with nodules, the European Thyroid Association convened a panel of international experts to set up European guidelines on US risk stratification of thyroid nodules. Based on a review of the literature and on the American Association of Clinical Endocrinologists, American Thyroid Association, and Korean guidelines, the panel created the novel European Thyroid Imaging and Reporting Data System, called EU-TIRADS. This comprises a thyroid US lexicon; a standardized report; definitions of benign and low-, intermediate-, and high-risk nodules, with the estimated risks of malignancy in each category; and indications for FNA. Illustrated by numerous US images, the EU TIRADS aims to serve physicians in their clinical practice, to enhance the interobserver reproducibility of descriptions, and to simplify communication of the results. PMID- 29167763 TI - Questionnaire-based Prevalence of Food Insecurity in Iran: A Review Article. AB - Background: Data on the questionnaire-based prevalence of food insecurity are needed to develop food and nutrition security studies and policies. The present study aimed to assess the questionnaire-based prevalence of food insecurity in Iran. Methods: A systematic search of cross-sectional studies were conducted on databases including PubMed, Google Scholar, Scopus, Magiran, Iranmedex, SID and Medlib up to 29 Oct 2015. Estimation of food insecurity prevalence was according to the instruments including 9-items-HFIAS, 18 and 6-items USDA (US-HFSSM) and Radimer/Cernel food security questionnaires. Pooled effect was estimated using random-effect model and heterogeneity was assessed by Cochran's Q and I2 tests. Results: Thirteen articles included in the study based on screening and assessment of eligibility. The questionnaire-based prevalence of food insecurity was 49.2% (CI95%: 43.8-54.6). The according to sub-groups analysis, the food insecurity without and with hunger was 29.6% (CI95%: 25.7-33.6) and 19.2% (CI95%: 16-22.3), respectively. Conclusion: The about half of the population were food insecure. The food insecurity without hunger was more than the food insecurity with hunger. An ongoing food insecurity assessment system is needed to support evidence-informed policy and to plan interventions to increase the food security in different areas. PMID- 29167762 TI - LncRNA Expression in CD4+ T Cells in Neurosyphilis Patients. AB - Recent studies have shown that several long noncoding RNAs (lncRNAs) are involved in regulating the immune response to cope with pathogenic invasion. To date, the roles of lncRNAs in the CD4+ T cell response to Treponema pallidum (T. pallidum) infection in neurosyphilis patients remain unknown. The mRNA and lncRNA expression profiles of CD4+ T cells that were isolated from neurosyphilis patients and healthy controls were analyzed by microarray. A total of 2258 lncRNAs and 1728 mRNAs were identified as over-expressed or under-expressed, respectively (fold change > 1.5) in the CD4+ T cells of neurosyphilis patients compared to the healthy controls. The lncRNA-mRNA co-expression network showed that 59 lncRNAs showed significant differences along with significantly different mRNAs. Among the 59 gene pairs, the LOC79999 mRNA was positively correlated with the RP11-160E2.16, RP11-160E2.11, and RP11-160E2.19 lncRNAs, and the NKX1-1 mRNA was positively correlated with the RP11-1398P2.1, RP11-160E2.19, and XLOC_003422 lncRNAs. The following five mRNAs were correlated with two differential lncRNAs: DUSP16, AP000349.1, FAM115C, TIMM8A, and SMCHD1. Gene Ontology (GO) analysis revealed that the differentially expressed coding genes were mainly involved in biological processes and the top 4 terms that associated with above-mentioned differentially expressed coding genes were as follows: defense response to fungus, defense response to bacterium, killing of cells of other organism and disruption of cells of another organism. A subsequent pathway analysis was also conducted, and several pathways, including the T cell receptor, MAPK, and TGF beta signaling pathways, were associated with the differentially expressed mRNAs. This study reveals the differential expression profiles of lncRNAs in the CD4+ T cell response to the T. pallidum infection in neurosyphilis patients. LncRNAs are involved in key biological processes that comprise the CD4+ T cell response to the T. pallidum infection. PMID- 29167764 TI - Barriers and Facilitators of Health Literacy among D/deaf Individuals: A Review Article. AB - Background: The implication of health literacy is the ability of individuals to find, understand, and use their required health information from reliable sources. It is an indicator of the individuals' participation in their own medical decision-making. Deaf individuals have limited health literacy and poor health status due to low literacy. Hence, this review was conducted to understand barriers and facilitators influencing health literacy among deaf community. Methods: We searched the ISI Web of Sciences, Scopus, and Medline from 1987 to 2016. Seventy-three papers were analyzed thematically. Results: We found three primary themes, including inadequate health literacy, barriers, and facilitators to accessing health information and health care services among deaf individuals. Facilitators were composed of four sub-theme including legal activities protecting the right of deaf patients to accessing health services, training health professionals about effective communication with deaf patients, providing sign language interpreter services, and developing deaf-tailored educational health programs and materials. Conclusion: Closing the deaf cultural gap and their limited access to health information are achievable through the removal of the communication barriers, allowing deaf individuals with more access to health learning opportunities, and informing the hearing community about the communicative skills of deaf individuals. PMID- 29167765 TI - Role of Molecular Biology in Cancer Treatment: A Review Article. AB - Background: Cancer is a genetic disease and mainly arises due to a number of reasons include activation of onco-genes, malfunction of tumor suppressor genes or mutagenesis due to external factors. Methods: This article was written from the data collected from PubMed, Nature, Science Direct, Springer and Elsevier groups of journals. Results: Oncogenes are deregulated form of normal proto oncogenes required for cell division, differentiation and regulation. The conversion of proto-oncogene to oncogene is caused due to translocation, rearrangement of chromosomes or mutation in gene due to addition, deletion, duplication or viral infection. These oncogenes are targeted by drugs or RNAi system to prevent proliferation of cancerous cells. There have been developed different techniques of molecular biology used to diagnose and treat cancer, including retroviral therapy, silencing of oncogenes and mutations in tumor suppressor genes. Conclusion: Among all the techniques used, RNAi, zinc finger nucleases and CRISPR hold a brighter future towards creating a Cancer Free World.

AB - Background: We tried to investigate the effect of PM2.5 on daily counts of outpatient visits in the Guang'anmen Hospital to determine if short-term PM2.5 exposure with extremely high concentration affects cardiopulmonary function of Beijing residents. Methods: Outpatient visits and PM2.5 data from 01/11/2011 to 03/31/2013 were extracted from the Guang'anmen Hospital and the American Embassy in Beijing, respectively. Followed by using a semi-parametric generalized additive model (GAM) with time dependent covariates, we analyzed the association between PM2.5 concentrations and daily count of outpatient visits on Day 0, 1, 2, 3, 4 and 5 of PM2.5 exposure. Results: Overall, 284354 subjects were collected. There were significant associations of short-term PM2.5 exposures with outpatient visits for cardiopulmonary diseases (P<0.05). Specifically, a 10 MUg/m3 increase in PM2.5 was positively associated with a 0.74% of increase in angina visit on the first day and 0.50% increased visit on the second day (P<0.05). With an increase in PM2.5, the cough and respiratory visits significantly decreased by 0.17% and 0.30% on the first day, respectively (P<0.05). However, there were significant positive associations of PM2.5 with increased cough and respiratory visits (increased by 0.17% and 0.10%, respectively) on the fifth day (P<0.05). Conclusion: Our association studies showed an instant effect of PM2.5 level on cardiovascular outpatient visit in the Guang'anmen Hospital in Beijing while a lag effect on respiratory outpatient visits. PMID- 29167767 TI - TP53 Gene Polymorphisms and Occupational Skin Cancer Risks for Workers of Glass Fiber Manufacture. AB - Background: Determining the role of genetic markers in individual sensitivity to chemical exposures raises a possibility of risk assessment of occupational diseases and their prevention. This paper focuses on the results of the identification of molecular-genetic markers associated with occupational skin cancer susceptibility. This study aimed to explore an association between polymorphisms of the TP53 tumor suppressor gene and a risk of developing occupational skin neoplasms. Methods: This case-control study was conducted on 71 workers with occupational skin neoplasms, 99 healthy workers, and 100 healthy population-based controls in Bashkortostan Republic, Russia in 2015. Genotyping of TP53 polymorphisms (rs1042522, rs1625895, and rs17878362) was performed by restriction fragment length polymorphism analysis of genomic DNA extracted from peripheral blood. Odds ratios and 95% confidence intervals were calculated to measure the strength of the association. Results: Subjects carrying allele C of rs1042522 were associated with an increased risk of occupational skin neoplasms [P=0.027, odds ratio (OR)=1.97, 95% confidence intervals (CI) 1.08-3.63]. An increased risk was also associated with allele 16bp of rs17878362 (P=0.010, OR=3.32, 95 % CI=1.31-8.78) and allele A of rs1625895 (P=0.003, OR = 5.45, 95 % CI = 1.72-19.15). Conclusion: The polymorphic variants rs1042522, rs1625895 and rs17878362 of the TP53 gene are related to increased risks of occupational skin cancer. This study suggests the potential use of molecular-genetic data to assess increased individual risks of the development and prognosis of occupational skin neoplasms. PMID- 29167768 TI - Correlation Analysis between Obstructive Sleep Apnea Syndrome (OSAS) and Heart Rate Variability. AB - Background: Heart rate variability (HRV) represents the sympathetic nervous system activity induced by apnea or hypopnea events among OSAS patients. However, few studies have been conducted to clarify the association between HRV parameters and polysomnography (PSG) diagnostic indices. In our study, we postulate that the prevalence of cardiac arrhythmias is associated with OSAS, and HRV parameters may be an effective method for OSAS screening. Methods: Overall, 168 participants had been collected from 2011 to 2016 in the Second Affiliated Hospital of Soochow University. By apnea-hypopnea index (AHI), patients were separated into three subsets: AHI < 5 as control group, 5<=AHI<30 as mild-moderate OSAS group and AHI>=30as severe OSAS group. HRV and PSG parameters were collected based on electrocardiography and polysomnography system. Correlation analyses between standard deviation of R-R intervals (SDNN), SDNN index, RMSSD, PNN50, low frequency (LF), high frequency (HF) and LF/HF ratio and the AHI, ODI and MI were performed by Spearman's correlation analysis. Results: Compared with control group (64.5%) or mild-moderate OSAS group (67.3%), the prevalence of arrhythmias was considerably greater in severe OSAS group (P<0.05). Moreover, we demonstrated that LF/HF was greater in two OSAS groups than the normal group. Conclusion: Correlation analyses revealed a significant and positive relation between the LF/HF and AHI, ODI and MI in OSAS patients. Severe OSAS could be attributed to enhanced danger of incident arrhythmia. LF/HF ratio as a relevant feature may be an effective parameter for detecting OSAS. PMID- 29167769 TI - Differences in Health-related Quality of Life and Mental Health by Living Arrangement among Korean Elderly in the KNHANES 2010-2012. AB - Background: This cross-sectional study examined the association between types of living arrangements, quality of life, and mental health of the Korean elderly. Methods: We used secondary data analysis from the data of 4248 elderly people aged 65 yr or older that completed the Korea National Health and Nutrition Examination Survey (2010-2012). Data concerning participants' demographic characteristics, living arrangements, quality of life, and mental health were used. Data were analyzed using the SAS survey procedure. Results: The living arrangements were as follows: living alone=18.3%, living with a spouse only =44.5%, living with family without a spouse =13.4%, and living with family including a spouse=23.8%. Mobility, self-care, usual activity, pain/discomfort, and anxiety/depression significantly differed by living arrangement. In the final model corrected for covariance, for the elderly living with their families without a spouse compared to the elderly living with a spouse only, the odds ratios were the following: stress =1.40 (95% CI: 1.03-1.91), depression=1.48 (95% CI: 1.07-2.04), and suicidal ideation=1.48 (95% CI: 1.10-2.00). The odds ratio of suicidal ideation of elderly living alone compared to the elderly living with a spouse only was 1.32 (95% CI: 1.01-1.72). Finally, the elderly living with family without a spouse or living alone had an increased risk of stress, depression, and suicidal ideation. In addition, they had decreased health-related quality of life. Conclusion: Health-related quality of life and mental health differ by living arrangement in elderly adults. Therefore, interventions to improve quality of life and mental health for the elderly who are living without a spouse are necessary. PMID- 29167770 TI - A Multi-center Study on Improvement in Life Quality of Pediatric Patients with Asthma via Continuous Care. AB - Background: To analyze and summarize the effect of continuous care on the life quality and control of asthma of pediatric patients with asthma discharged from multiple hospitals. Methods: Retrospective analysis was carried out on 172 pediatric patients with asthma aged between 6 and 11 yr old randomly selected from those admitted to five hospitals between January 2014 and December 2015. Among these 172 patients, only 86 (intervention group) received the continuous care between January 2015 and December 2015, while the rest (control group) did not receive from January 2014 and December 2014. Results: After the patients in the intervention group were discharged from the hospital, the ratio of practical forced expiratory volume in one second (FEV1) to the expected FEV1 at the 12th month was (90.28+/-10.35)%, and the ratio of peak expiratory flow to the expected value was (84.24+/-3.43)%, respectively higher than those [(82.73+/-8.86)% and (75.80+/-4.67)%] in the control group. Regarding pediatric asthma quality of life questionnaire (PAQLQ) between the intervention group and the control group, the difference had statistical significance (Z=-7.254, P<0.05). Childhood asthma control test (C-ACT) comparison between the intervention group and the control group indicated that the difference had statistical significance (Z=-7.918, P<0.05). Conclusion: Continuous care can improve the pediatric patient's pulmonary function and life quality, and effectively control the asthmatic symptoms. PMID- 29167771 TI - Somatic-vegetative Symptoms Evolution in Postmenopausal Women Treated with Phytoestrogens and Hormone Replacement Therapy. AB - Background: The purpose of this study was to compare the effects of the phytoestrogens in relieving and/or suppressing the specific somatic-vegetative symptoms of menopause with those of the hormone therapy, administered in small doses. Methods: The study was conducted in the County Clinical Emergency Hospital Oradea - Obstetric-Gynecological Ambulatory, and in private obstetrics-gynecology cabinets from Bihor County (NW Romania), from November 2011 to January 2014. Overall, 325 patients clinically diagnosed with specific postmenopausal symptomatology and not previously treated with phytoestrogens or hormone replacement therapy (HRT), were divided into 3 groups. Symptom assessment was performed with a standardized questionnaire named Menopause Rating Scale (MRS) in three phases: beginning of the treatment, after six months, and after one year. The administered doses for three different groups were as follows: 1 mg estradiol and 0.5 mg norethisterone acetate (NETA) p.o. daily (i.e. for the HRT group); 40 mg of isoflavones p.o. daily - i.e. 2 capsules of 40% standardized extract containing 20 mg of pure isoflavones: Genistein, Daidzein, and Glycitein (i.e. for the group with phytoestrogens); and no trreatment for the control group. Results: The evolution of the somatic-vegetative symptoms was better in both groups treated either with phytoestrogens or HRT (P<0.001) as opposed to the higher percentage of patients with stationary symptoms in the control group (i.e. 37.74% for control group, 16.13% for the group treated with phytoestrogens, respectively 18.95% for the group treated with HRT). Conclusion: Twelve months treatment study is a favorable evidence for the use of soy derived phytoestrogens in the treatment of somatic-vegetative symptoms at postmenopausal women. PMID- 29167772 TI - Guiding Effect of Serum Procalcitonin (PCT) on the Antibiotic Application to Patients with Sepsis. AB - Background: This study aimed to investigate the guiding effect of serum procalcitonin (PCT) on the antibiotic application to patients with sepsis. Methods: Ninety-eight patients with sepsis treated in Renmin Hospital of Wuhan University, China from 2015-2017 were enrolled. They were divided into two equal groups of control group and the observation group. Patients in the observation group received the antibiotic therapy guided by PCT while patients in the control group received the regular antibiotic therapy. The conventional indexes, prognosis and clinical effects of the two groups were compared. Results: There were no statistical significance in the differences of the Acute Physiology and Chronic Health Evaluation II (APACHE-II) scores C-reactive protein (CRP) and white blood cell count (WBC) levels between the two groups. The duration of the antibiotic application to patients in the observation group was (7.74+/-0.61) d which was (10.22+/-0.78) d shorter than that to patients in the control group. The difference was statistically significant (P<0.05). The Intensive Care Unit (ICU) stay time and the hospital stays of patients in the observation group were shorter than those of patients in the control group. The difference had statistical significance (P<0.05). The difference in 30-day-recurrence rate and 30 day-mortality of the patients in the two groups had no statistical significance. There was statistically significant difference in the comparison of the clinical effects between the two groups. Conclusion: Guiding effects of the serum PCT on the application of antibiotics to patients with sepsis shorten the usage time of the antibiotics, ICU stay time and hospital stays. PMID- 29167773 TI - Prevalence of Aflatoxin Contamination in Herbs and Spices in Different Regions of Iran. AB - Background: Mycotoxins are natural toxins, produced by several fungal species and are associated with morbidity or even mortality in animals, plants, and humans. In this study, 120 samples of herbs and spices in both bulk and packaged forms were prepared in order to measure aflatoxin level in different regions of Iran. Methods: The aflatoxin was extracted during Mar to May 2015, using 80% methanol and then purified via immunoaffinity column. Measurements were performed, using high-performance liquid chromatography, equipped with a fluorescence detection system at excitation and emission wavelengths of 365 and 435 nm, respectively. Results: The highest prevalence of aflatoxin contamination in food products was attributed to aflatoxin B1 (30.8%). In addition, the highest prevalence of aflatoxin contamination was reported in red pepper (100%). Examination of effective factors indicated the substantial impact of moisture on aflatoxin level (P=0.046). Conclusion: Even at low levels of aflatoxin, contamination could be a serious threat, given the prevalent use of spices (either raw or not) as ingredients in food preparation. Therefore, regular monitoring of spices, especially chili pepper, is highly recommended. PMID- 29167774 TI - Anthropometric Indices as Predictors of Coronary Heart Disease Risk: Joint Modeling of Longitudinal Measurements and Time to Event. AB - Background: The prevalence of overweight and obesity have increased dramatically worldwide and together they constitute a major risk factor for coronary heart disease (CHD). The aim of this study was to assess the repeated measurements of body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR) and waist to height ratio (WHtR) in predicting CHD incidence. Methods: This longitudinal study was conducted within the framework of the Tehran Lipid and Glucose Study between 1999-2011, on 1959 women and 1371 men participants' ages >=30 yr, without a history of CVD. A joint modeling approach was utilized for data analysis using R software. The resulting joint model allowed measuring alpha (quantifies the association between anthropometric indices up to time t and the hazard for CHD event at the same time point). Results: About 9% of the participants (7.1% of the women and 11.7% of the men) experienced CHD event during follow-up. The results indicated a significant linear increasing trend in BMI, WC, WHR, and WHtR over time (P<0.001). The increased risk of CHD event in females increases with the values of BMI (alpha= 0.004, P=0.023), WC (alpha= 0.018, P=0.009), WHR (alpha= 0.067, P=0.014) and WHtR (alpha= 0.106, P=0.002). Furthermore, in males the risk of CHD risk increases by the values of BMI (alpha= 0.005, P=0.032), WC (alpha= 0.019, P=0.008), WHR (alpha= 0.043, P=0.015) and WHtR (alpha= 0.096, P=0.002). Conclusion: By jointly modeling longitudinal data with time-to-event outcomes, our study revealed that WHtR is superior to other indices in predicting CHD incidence. PMID- 29167775 TI - A Model for the Development of Hospital Beds Using Fuzzy Analytical Hierarchy Process (Fuzzy AHP). AB - Background: This study aimed to identify and prioritize factors affecting the development of military hospital beds and provide a model using fuzzy analytical hierarchy process (Fuzzy AHP). Methods: This applied study was conducted in 2016 in Iran using a mixed method. The sample included experts in the field of military health care system. The MAXQDA 10.0 and Expert Choice 10.0 software were used for analyzing the collected data. Results: Geographic situation, demographic status, economic status, health status, health care centers and organizations, financial and human resources, laws and regulations and by-laws, and the military nature of service recipients had effects on the development of military hospital beds. The military nature of service recipients (S=0.249) and economic status (S=0.040) received the highest and lowest priorities, respectively. Conclusion: Providing direct health care services to the military forces in order to maintain their dignity, and according to its effects in the crisis, as well as the necessity for maintaining the security of the armed forces, and the hospital beds per capita based on the existing laws, regulations and bylaws are of utmost importance.

PMID- 29167777 TI - Age and Spatial Peculiarities of Non-neoplastic Diseases of the Skin and Subcutaneous Tissue in Kazakhstan, 2003-2015. AB - Background: Arrangement of effective management aimed at improving dermatological services and consistent care of patients with skin diseases depends on understanding the epidemiological situation. Methods: This retrospective study presents an epidemiological assessment of non-neoplastic skin and subcutaneous tissue diseases in Kazakhstan registered in 2003-2015. Results: The yearly incidence rate of the diseases among the whole population was in average 3,341.8+/-121.1 per 100000 population. This represents 4835.0+/-156.1 for children, 5503.2+/-141.8 for adolescents and 2646.6+/-106.7 for adults per 100000 inhabitants. Space and time incidence rate was evaluated according to the administrative division. The overall trend decreased to 3.5% in children to 2.8% in adolescents to 1.9%, and in adults to 3.9%. Considerable variation in rates was seen across the country, with highest rates in East Kazakhstan, Mangystau and Aktobe regions, the lowest - in Atyrau and South-Kazakhstan regions. Conclusion: Non-neoplastic diseases of skin and subcutaneous tissue continue to be an urgent public health problem, especially among children in many regions of Kazakhstan. PMID- 29167778 TI - Functional Recovery of Patient Whit Ischemic Stroke: Case Report. AB - Vascular lesions of the central nervous system are one of the most important and topical problems in modern neuro-pathology. Bulgaria is among the first in morbidity and mortality from cerebrovascular diseases. Because of the significant medical and social importance of this pathology resulting in severe disabling of most survivors, we aimed to explore the effectiveness of kinesitherapeutic methodology applied in the recovery of a patient with ischemic stroke. We present a case of a 69-old patient admitted in the Neurological Ward of "St. George Hospital in Plovdiv in 2015, Bulgaria with right hemiparesis due to ischemic stroke in the basin of the left middle cerebral artery. The applied Kinesi therapeutic methodology included various techniques like Kabat's Bobath's methods as well as training in equilibrium and walking. The patient obtained satisfactory results in terms of movement of the body and preserving the equilibrium, improvement of voluntary movement of the upper and lower right limb achieved via the help of some compensatory mechanisms. Despite the applied Kinesitherapy, the patient failed to gain independence in daily activities. We ascribe this satisfactory recovery only to the short period of application of kinesitherapeutic methodology. For a better recovery of patients with cerebrovascular disease, a continuous multidisciplinary approach is needed.

PMID- 29167787 TI - Medicine Availability and Prescribing Policy for Non-Communicable Diseases in the Western Balkan Countries. AB - Background: During the transition processes, the Western Balkan countries were affected by conflicts and transition-related changes. Life expectancy in these countries is lower, while the mortality from non-communicable diseases (NCDs) is higher in comparison with western and northern parts of Europe. The primary aim of this study was to analyze the treatment possibilities for the most common NCDs in the Western Balkan countries. The secondary aim was to understand and compare the policies regarding prescribing-related competencies of family physicians. Methods: In June and July 2017, a document analysis was performed of national positive medicines lists, strategic documents, and clinical guidelines for the treatment of the most frequent NCDs; arterial hypertension, diabetes, hyperlipidemia, asthma, and chronic obstructive pulmonary disease (COPD). All text phrases that referred to medicines prescribing were extracted and sorted into following domains: medicine availability, prescribing policy, and medication prescribing-related competencies. Results: Possibilities for treatment of arterial hypertension, diabetes, hyperlipidemia, asthma, and COPD vary across the Western Balkan countries. This variance is reflected in the number of registered medicines, number of parallels, and number of different combinations, as well as restrictions placed on family physicians in prescribing insulin, inhaled corticosteroids, statins and angiotensin II receptor blockers (ARBs), without consultant's recommendation. Conclusion: Western Balkan countries are capable of providing essential medicines for the treatment of NCDs, with full or partial reimbursement. There are some exceptions, related to statins, newer generation of oral antidiabetic agents and some of the antihypertensive combinations. Prescribing-related competences of family physicians are limited. However, this practice is not compliant to the practices of family medicine, its principles and primary care structures, and may potentially result in increased health-care financial ramifications to both the system and patients due to frequent referrals to the specialists. PMID- 29167788 TI - Examining Capacity and Functioning of Bicycle Coalitions: A Descriptive Study. AB - Background: Bicycle coalitions represent a strong partner in creating bike friendly communities through advocacy for physical infrastructure, encouragement for biking, or education about safety. Despite their versatility, little is known about their functioning. Therefore, the purpose of this study was to examine capacity, strengths, and weaknesses of these organizations. Methods: Bicycle coalitions/advocacy groups from English-speaking countries were recruited to take part in an online survey via email invitation. The survey addressed basic information about the coalition (community demographics, location), leadership, communication strategies, coalition priorities, barriers to programming/activities, and partners. Results: Coalitions (n = 56) from four countries completed the survey. Most coalitions operated as a non-profit (n = 44, 95.7%), 45% (n = 21) have paid staff as leaders, while 37% (n = 17) have volunteers as leaders. The following skills were represented in coalitions' leadership: fundraising (n = 31, 53.4%), event planning (n = 31, 53.4%), urban planning (n = 26, 44%), and policy/legislation expertise (n = 26, 44.8%). Education (n = 26, 63.4%) and encouragement (n = 25, 61.6%) were viewed as top priorities and the safety of bicyclists (n = 21, 46.7%) and advocacy for infrastructure and policy (n = 22, 48.9%) is the focus of most activities. A lack of financial resources (n = 36, 81.8%) and capable personnel (n = 25, 56.8%) were significant barriers to offering programming in the community and that the availability of grants to address issues (n = 38, 86.4%) would be the top motivator for improvements. Conclusion: Bike coalitions represent a critical partner in creating activity-friendly environments and understanding their capacity allows for creating skill/capacity building intervention programs, development of effective toolkits and fostering strong collaborations to address physical inactivity. PMID- 29167789 TI - Radical SAM Enzymes in the Biosynthesis of Ribosomally Synthesized and Post translationally Modified Peptides (RiPPs). AB - Ribosomally-synthesized and post-translationally modified peptides (RiPPs) are a large and diverse family of natural products. They possess interesting biological properties such as antibiotic or anticancer activities, making them attractive for therapeutic applications. In contrast to polyketides and non-ribosomal peptides, RiPPs derive from ribosomal peptides and are post-translationally modified by diverse enzyme families. Among them, the emerging superfamily of radical SAM enzymes has been shown to play a major role. These enzymes catalyze the formation of a wide range of post-translational modifications some of them having no counterparts in living systems or synthetic chemistry. The investigation of radical SAM enzymes has not only illuminated unprecedented strategies used by living systems to tailor peptides into complex natural products but has also allowed to uncover novel RiPP families. In this review, we summarize the current knowledge on radical SAM enzymes catalyzing RiPP post translational modifications and discuss their mechanisms and growing importance notably in the context of the human microbiota. PMID- 29167790 TI - Engineered Nickel Oxide Nanoparticle Causes Substantial Physicochemical Perturbation in Plants. AB - Concentration of engineered nickel oxide nanoparticle (NiO-NP) in nature is on the rise, owing to large scale industrial uses, which have accreted the scope of its exposure to plants, the primary producers of the ecosystem. Though an essential micronutrient for the animal system, supported by numerous studies confirming its toxicity at higher dosages, nickel oxide is graded as a human carcinogen by WHO. A few studies do depict toxicity and bioaccumulation of nickel in plants; however, interaction of NiO-NP with plants is not well-elucidated. It is known that exposure to NiO-NP can incite stress response, leading to cytotoxicity and growth retardation in some plants, but a defined work on the intricate physicochemical cellular responses and genotoxic challenges is wanting. The present study was planned to explore cytotoxicity of NiO-NP in the model plant, Allium cepa L., its internalization in the tissue and concomitant furore created in the antioxidant enzyme system of the plant. The prospect of the NiO-NP causing genotoxicity was also investigated. Detailed assessments biochemical profiles and genotoxicity potential of NiO-NP on A. cepa L. was performed and extended to four of its closest economically important relatives, Allium sativum L., Allium schoenoprasum L., Allium porrum L., and Allium fistulosum L. Growing root tips were treated with seven different concentrations of NiO-NP suspension (10-500 mg L-1), with deionised distilled water as negative control and 0.4 mM EMS solution as positive control. Study of genotoxic endpoints, like, mitotic indices (MI), chromosomal aberrations (CAs), and chromosome breaks confirmed NiO NP induced genotoxicity in plants, even at a very low dose (10 mg L-1). That NiO NP also perturbs biochemical homeostasis, disrupting normal physiology of the cell, was confirmed through changes in state of lipid peroxidation malonaldehyde (MDA), as well as, in oxidation marker enzymes, like catalase (CAT), super oxide dismutase (SOD), and guiacol peroxidase (POD) activities. It was evident that increase in NiO-NP concentration led to decrease in MIs in all the study materials, concomitant with a spike of stress-alleviating, antioxidant enzymes CAT, POD, SOD, and significant increase in MDA formation. Hence, it can be confirmed that NiO-NP should be treated as an environmental hazard. PMID- 29167791 TI - Is Delirium the Cognitive Harbinger of Frailty in Older Adults? A Review about the Existing Evidence. AB - Frailty is a clinical syndrome defined by the age-related depletion of the individual's homeostatic reserves, determining an increased susceptibility to stressors and disproportionate exposure to negative health changes. The physiological systems that are involved in the determination of frailty are mutually interrelated, so that when decline starts in a given system, implications may also regard the other systems. Indeed, it has been shown that the number of abnormal systems is more predictive of frailty than those of the abnormalities in any particular system. Delirium is a transient neurocognitive disorder, characterized by an acute onset and fluctuating course, inattention, cognitive dysfunction, and behavioral abnormalities, that complicates one out of five hospital admissions. Delirium is independently associated with the same negative outcomes of frailty and, like frailty, its pathogenesis is usually multifactorial, depending on complex inter-relationships between predisposing and precipitating factors. By definition, a somatic cause should be identified, or at least suspected, to diagnose delirium. Delirium and frailty potentially share multiple pathophysiologic mechanisms and pathways, meaning that they could be thought of as the two sides to the same coin. This review aims at summarizing the existing evidence, referring both to human and animal models, to postulate that delirium may represent the cognitive harbinger of a state of frailty in older persons experiencing an acute clinical event. PMID- 29167792 TI - Translation of the 5D Itching Scale from English to Malay, and Its Validation among Patients with Chronic Kidney Disease in Malaysia. AB - Introduction: Several tools have been developed to assess the severity of pruritus. In Malaysia, no tool has been validated to assess pruritus in patients with chronic kidney disease (CKD). Therefore, the aim of our study was to validate the Malay 5D itching scale (M5D-IS) among patients with CKD in Malaysia. Method: The English version of the 5D-IS was translated into Malay according to International Guidelines. Face and content validity was determined by an expert panel and pilot tested in patients with end-stage renal disease (ESRD). The M5D IS was then validated in a tertiary hospital in Malaysia from May to June 2016. We recruited patients with (i.e., patients with ESRD) and without pruritus (i.e., patients with stage 1-3 CKD) (to determine if the M5D-IS could discriminate between the two groups), and administered the M5D-IS at baseline and 2 weeks later. Exploratory factor analysis was used to examine the construct validity. Internal consistency was assessed using Cronbach's alpha and intraclass correlation coefficient was calculated to assess the reliability of the instrument. Results: A total of 70 participants were recruited (response rate = 100%). The majority were males (51.4%) and Malay (67.1%). Exploratory factor analysis revealed that the 5D-IS had 2-factor loadings: "daily routine activity" and "pattern of itching," which explained 77.7% of the variance. The overall score of the M5D-IS, as well as for each domain, was significantly worse in participants with pruritus (9.83 +/- 0.35), compared to those without pruritus (5.51 +/- 0.93, p < 0.001). The overall Cronbach's alpha for the M5D-IS was (0.861), indicating adequate internal consistency. At test-retest, the intraclass correlation coefficient was significantly correlated. Conclusion: The M5D-IS was found to be a valid and reliable instrument to assess pruritus among patients with CKD in Malaysia. PMID- 29167793 TI - Health and Lifestyles Factors Associated With Osteoarthritis among Older Adults in Portugal. AB - Objective: This study aimed to identify independent associations of sociodemographic, functionality, physical activity, physical and mental health, and osteoarthritis (OA), among older adults. Methods: A sample of 1,645 older adults (50+ years) observed by rheumatologists, from EpiReumaPt, a population based study was analyzed. A structured interview included sociodemographic data, chronic non-communicable disease, and physical activity. Functional ability was assessed by the Health Assessment Questionnaire Disability Index; depression and anxiety were assessed by Hospital Anxiety and Depression Scale. OA (knee OA and/or hip OA and/or hand OA) was defined after medical evaluation by rheumatologists according to expert opinion combined with the fulfillment of the American College of Rheumatology classification criteria. Results: 1,059 participants (64.9%) met the OA classification criteria. Statistically significant differences were found between persons with and without OA in all sociodemographic variables, non-communicable diseases, functional status, physical activity, depression, and anxiety. In the unadjusted logistic regression models, all variables were associated with OA. The final adjusted model explained 32% of the variance. Those who are female with higher age, have more than five comorbidities, and lower levels of function and physical activity were more likely to meet the criteria for a diagnosis of OA. Discussion: We have analyzed data from a population-based study and found that a diagnosis of OA was independently associated with age, female gender, higher number of comorbidities, physical disability, and low levels of physical activity. These results reinforce the usefulness of the development of a multidimensional assessment to design and test effective interventions for this population. PMID- 29167794 TI - Case Report of Urethritis in a Male Patient Infected with Two Different Isolates of Multiple Drug-Resistant Neisseria gonorrhoeae. AB - We report a brief description of a case suffering from bacterial urethritis, conjunctivitis, and arthritis, caused by two different isolates of multiple drug resistant Neisseria gonorrhoeae. Initial diagnosis was dependent on the patient history, clinical findings, symptoms, and the bacteriological data. Polymerase chain reaction confirmed the identification of the pathogens. Random amplified polymorphic DNA revealed two different patterns. Susceptibility testing was performed using Kirby-Bauer disk diffusion method and the minimum inhibitory concentration was also determined. It revealed multiple drug resistance associated with beta-lactamase production. Only gentamicin, rifampicin, and azithromycin were active against the test pathogens. A dual therapy was initiated using gentamicin as well as azithromycin to treat the possible co-infection with Chlamydia trachomatis. Complete recovery of the patient achieved with resolved symptoms a week later. PMID- 29167796 TI - Tinnitus after Simultaneous and Sequential Bilateral Cochlear Implantation. AB - Importance: There is an ongoing global discussion on whether or not bilateral cochlear implantation should be standard care for bilateral deafness. Contrary to unilateral cochlear implantation, however, little is known about the effect of bilateral cochlear implantation on tinnitus. Objective: To investigate tinnitus outcomes 1 year after bilateral cochlear implantation. Secondarily, to compare tinnitus outcomes between simultaneous and sequential bilateral cochlear implantation and to investigate long-term follow-up (3 years). Study design: This study is a secondary analysis as part of a multicenter randomized controlled trial. Methods: Thirty-eight postlingually deafened adults were included in the original trial, in which the presence of tinnitus was not an inclusion criterion. All participants received cochlear implants (CIs) because of profound hearing loss. Nineteen participants received bilateral CIs simultaneously and 19 participants received bilateral CIs sequentially with an inter-implant interval of 2 years. The prevalence and severity of tinnitus before and after simultaneous and sequential bilateral cochlear implantation were measured preoperatively and each year after implantation with the Tinnitus Handicap Inventory (THI) and Tinnitus Questionnaire (TQ). Results: The prevalence of preoperative tinnitus was 42% (16/38). One year after bilateral implantation, there was a median difference of -8 (inter-quartile range (IQR): -28 to 4) in THI score and -9 (IQR: -17 to -9) in TQ score in the participants with preoperative tinnitus. Induction of tinnitus occurred in five participants, all in the simultaneous group, in the year after bilateral implantation. Although the preoperative and also the postoperative median THI and TQ scores were higher in the simultaneous group, the median difference scores were equal in both groups. In the simultaneous group, tinnitus scores fluctuated in the 3 years after implantation. In the sequential group, four patients had an additional benefit of the second CI: a total suppression of tinnitus compared with their unilateral situation. Conclusion: While bilateral cochlear implantation can have a positive effect on preoperative tinnitus complaints, the induction of (temporary or permanent) tinnitus was also reported.

PMID- 29167797 TI - A Subset of Dogs with Presumptive Idiopathic Epilepsy Show Hippocampal Asymmetry: A Volumetric Comparison with Non-Epileptic Dogs Using MRI. AB - MRI-acquired volumetric measurements from 100 dogs with presumptive idiopathic epilepsy (IE) and 41 non-epileptic (non-IE) dogs were used to determine if hippocampal asymmetry exists in the IE as compared to the non-IE dogs. MRI databases from three institutions were searched for dogs that underwent MRI of the brain and were determined to have IE and those that were considered non-IE dogs. Volumes of the right and left hippocampi were measured using Mimics(r) software. Median hippocampal volumes of IE and non-IE dogs were 0.47 and 0.53 cm3, respectively. There was no significant difference in overall hippocampal volume between IE and non-IE dogs; however, IE dogs had greater hippocampal asymmetry than non-IE dogs (P < 0.012). A threshold value of 1.16 from the hippocampal ratio had an 85% specificity for identifying IE-associated asymmetry. Thirty five percent of IE dogs had a hippocampal ratio >1.16. Asymmetry was not associated with any particular hemisphere (P = 0.67). Our study indicates that hippocampal asymmetry occurs in a subset of dogs with presumptive idiopathic/genetic epilepsy, suggesting a structural etiology to some cases of IE.

AB - Tuberculosis produces two clinical manifestations: active and latent (non apparent) disease. The latter is estimated to affect one-third of the world population and constitutes a source of continued transmission should the disease emerge from its hidden state (reactivation). Methods to diagnose latent TB have been evolving and aim to detect the disease in people who are truly infected with M. tuberculosis, versus those where other mycobacteria, or even other pathologies not related to TB, are present. The current use of proteomic and transcriptomic approaches may lead to improved detection methods in the coming years. PMID- 29167795 TI - Managing Rheumatoid Arthritis with Dietary Interventions. AB - Self-help by means of dietary interventions can help in management of various disorders including rheumatoid arthritis (RA), a debilitating autoimmune disease. Dietary interventions necessitate a widespread appeal for both patients as well as clinicians due to factors including affordability, accessibility, and presence of scientific evidences that demonstrate substantial benefits in reducing disease symptoms such as pain, joint stiffness, swelling, tenderness and associated disability with disease progression. However, there is still an uncertainty among the community about the therapeutic benefits of dietary manipulations for RA. In the present review, we provide an account of different diets and their possible molecular mechanism of actions inducing observed therapeutic benefits for remission and management of RA. We further indicate food that can be a potential aggravating factor for the disease or may help in symptomatic relief. We thereafter summarize and thereby discuss various diets and food which help in reducing levels of inflammatory cytokines in RA patients that may play an effective role in management of RA following proper patient awareness. We thus would like to promote diet management as a tool that can both supplement and complement present treatment strategies for a better patient health and recovery.

It is manifested by a gradual accumulation of molecular alterations that lead to the decline of normal physiological functions in a time-dependent fashion. The ultimate goal of aging research is to develop therapeutic means to extend human lifespan, while reducing susceptibility to many age-related diseases including cancer, as well as metabolic, cardiovascular and neurodegenerative disorders. However, this first requires elucidation of the causes of aging, which has been greatly facilitated by the use of model organisms. In particular, the budding yeast Saccharomyces cerevisiae has been invaluable in the identification of conserved molecular and cellular determinants of aging and for the development of approaches to manipulate these aging determinants to extend lifespan. Strikingly, where examined, virtually all means to experimentally extend lifespan result in the induction of cellular stress responses. This review describes growing evidence in yeast that activation of the integrated stress response contributes significantly to lifespan extension. These findings demonstrate that yeast remains a powerful model system for elucidating conserved mechanisms to achieve lifespan extension that are likely to drive therapeutic approaches to extend human lifespan and healthspan. PMID- 29167800 TI - Cross-species complementation of bacterial- and eukaryotic-type cardiolipin synthases. AB - The glycerophospholipid cardiolipin is a unique constituent of bacterial and mitochondrial membranes. It is involved in forming and stabilizing high molecular mass membrane protein complexes and in maintaining membrane architecture. Absence of cardiolipin leads to reduced efficiency of the electron transport chain, decreased membrane potential, and, ultimately, impaired respiratory metabolism. For the protozoan parasite Trypanosoma brucei cardiolipin synthesis is essential for survival, indicating that the enzymes involved in cardiolipin production represent potential drug targets. T. brucei cardiolipin synthase (TbCLS) is unique as it belongs to the family of phospholipases D (PLD), harboring a prokaryotic-type cardiolipin synthase (CLS) active site domain. In contrast, most other eukaryotic CLS, including the yeast ortholog ScCrd1, are members of the CDP alcohol phosphatidyltransferase family. To study if these mechanistically distinct CLS enzymes are able to catalyze cardiolipin production in a cell that normally expresses a different type of CLS, we expressed TbCLS and ScCrd1 in CLS deficient yeast and trypanosome strains, respectively. Our results show that TbCLS complemented cardiolipin production in CRD1 knockout yeast and partly restored wild-type colony forming capability under stress conditions. Remarkably, CL remodeling appeared to be impaired in the transgenic construct, suggesting that CL production and remodeling are tightly coupled processes that may require a clustering of the involved proteins into specific CL-synthesizing domains. In contrast, no complementation was observed by heterologous expression of ScCrd1 in conditional TbCLS knockout trypanosomes, despite proper mitochondrial targeting of the protein. PMID- 29167801 TI - Breaking the bad: Bacillus blocks fungal virulence factors. AB - Fungal pathogens rely on the production of specific virulence factors during infection. Inhibiting such factors generally results in reduced fungal pathogenicity. Most studies in the past have focused on understanding the molecular mechanisms of fungal virulence factor expression during mono-culture, or during interaction with the host. However, a potentially important, second type of interaction has been less well studied thus far - the interplay of fungal pathogens of humans with other microbes found in their natural habitat. Specifically, whether environmental bacteria may impact fungal virulence factor production is largely unknown. In our recent work, we have identified the soil bacterium, Bacillus safensis, as a potent inhibitor of virulence factor production by two major fungal pathogens of humans, Cryptococcus neoformans, and Candida albicans. We determined that the anti-virulence factor mechanism is, at least in part, based on production of bacterial chitinases that target and destabilize the fungal cell surface. These findings describe a cross-kingdom interaction between an environmental bacterium and pathogenic fungi, and highlight the fungal cell wall as an attractive antifungal drug target. PMID- 29167802 TI - Shutdown of interferon signaling by a viral-hijacked E3 ubiquitin ligase. AB - Viruses manipulate cellular processes to create an environment favorable to replication. For most viruses, this includes subverting the expression of interferon (IFN), a signaling molecule that can stimulate production of a vast array of antiviral gene products. Rotavirus, a segmented double-stranded RNA virus that causes acute gastroenteritis in infants and young children, inhibits IFN expression through its nonstructural protein NSP1. This viral protein stifles IFN expression by inducing the degradation of host factors that are necessary for upregulating the activity of IFN genes. In the case of nearly all human and porcine rotavirus strains, NSP1 induces the ubiquitination-dependent proteasomal degradation of beta-transducin repeat containing protein (beta-TrCP), a host factor that plays an essential role in activating the IFN-transcription factor, NF-kappaB. Key to the process is the presence of a decoy sequence (degron) at the C-terminus of NSP1 that causes beta-TrCP to mistakenly bind NSP1 instead of its natural target, inhibitor-of-kappaB (IkappaB). In a recent report published by Davis et al [2017; mBio 8(4): e01213-17], we describe molecular requirements that govern NSP1 recognition of beta-TrCP, including an essential degron phosphorylation event, and the step-wise incorporation of NSP1 into hijacked cullin-RING E3 ligases (CRLs) that ubiquitinate and tag beta-TrCP for degradation. Notably, although beta-TrCP is chiefly recognized for its role as a master regulator of NF-kappaB signaling and IFN expression, beta-TrCP also controls the stability of checkpoint proteins implicated in numerous other cellular pathways with antiviral activities, including autophagy and apoptosis. Thus, the impact of NSP1 on creating an intracellular environment favorable to virus replication may extend well beyond the IFN signaling pathway.

PMID- 29167804 TI - Extracellular vesicle-mediated transport of non-coding RNAs between stem cells and cancer cells: implications in tumor progression and therapeutic resistance. AB - Recent years have witnessed intensive progress in studying extracellular vesicles (EVs), both for understanding their basic biology and contribution to variety of diseases, biomarker discovery, and their potential as gene delivery vectors and source of innovative therapies. As such, stem cell-derived EVs have contributed significant knowledge which led to the development of cell-free therapies in regenerative medicine. Although, the role of stem cell-derived EVs in maintaining stemness, differentiation and repairing tissue injuries is relatively well understood; however, knowledge about the contribution of stem cell-derived EVs in cancer progression is just emerging. The aim of this review is, therefore, to discuss the recent developments in stem cell-derived EVs and tumor progression, placing a particular focus on non-coding RNA (ncRNA) mediated cancer progression and resistance against therapies. This includes the failure of normal hematopoiesis and the progression of myeloid neoplasms, enhanced capacity of cancer cells to proliferate and metastasize, and the conversion of normal cells into cancer cells, activation of angiogenic pathways and dormancy in cancer cells. These processes are shared by mesenchymal stem cells (MSCs), cancer stem like-cells and cancer cells in an intricate intratumoral network in order to create self-strengthening tumor niche. In this context, EV-ncRNAs serve as mediators to relay bystander effects of secreting cancer stem cells (CSCs) into recipient cells for priming a tumor permissive environment and relaying therapeutic resistance. Collectively, this knowledge will improve our understandings and approaches in finding new therapeutic targets in the context of CSCs, which could be benefited through engineering EVs for innovative therapies. PMID- 29167805 TI - Clinical potential of mesenchymal stem/stromal cell-derived extracellular vesicles. AB - Within the last two decades mesenchymal stem/stromal cells (MSCs) emerged after hematopoietic stem cells as the second most investigated and applied somatic stem cell entity so far. MSCs mediate immunosuppressive as well as pro-regenerative activities. Against the initial assumption, MSCs may not primarily exert their therapeutic functions in a cellular but rather in a paracrine manner. Here, extracellular vesicles (EVs), such as exosomes and microvesicles, have been identified as major mediators of these paracrine effects. Meanwhile, MSC-EVs have been applied to an increasing amount of different animal models and were tested in a patient suffering from steroid-refractory acute graft-versus-host disease (acute GvHD) as well as in a patient cohort with chronic kidney disease. So far, the MSC-EV administration appears to be safe in humans and all tested animal models. Improvements were reported in all settings. Thus, MSC-EVs appear as promising novel therapeutic agents which might help to improve disease associated symptoms in millions of patients. Here, we review some of the milestones in the field, briefly discuss challenges and highlight clinical aspects of acute GvHD and its treatment with MSCs and MSC-EVs. PMID- 29167806 TI - Aplastic anemia is related to alterations in T cell receptor signaling. AB - Aplastic anemia (AA) is a disease characterized by bone marrow hematopoietic dysfunction and peripheral blood pancytopenia, which is thought to be mediated by an abnormal T cell-induced immune response. T cell receptor (TCR) signaling is pivotal for T cell development and function. An aberrant TCR signaling leads to an unbalanced immune system that can result in a range of immune-related disorders, including autoimmune diseases, chronic infections, and tumors. In this article, we briefly review the T cell immune pathophysiology of AA, the physiology of normal TCR signaling and its regulatory factors, and clinical and laboratory findings of TCR signaling molecules and their regulatory factors in AA.

PMID- 29167808 TI - Small incision lenticule extraction (SMILE) in the correction of myopic astigmatism: outcomes and limitations - an update. AB - Small Incision Lenticule Extraction (SMILE) is a flap-free intrastromal technique for the correction of myopia and myopic astigmatism. To date, this technique lacks automated centration and cyclotorsion control, so several concerns have been raised regarding its capability to correct moderate or high levels of astigmatism. The objective of this paper is to review the reported SMILE outcomes for the correction of myopic astigmatism associated with a cylinder over 0.75 D, and its comparison with the outcomes reported with the excimer laser-based corneal refractive surgery techniques. A total of five studies clearly reporting SMILE astigmatic outcomes were identified. SMILE shows acceptable outcomes for the correction of myopic astigmatism, although a general agreement exists about the superiority of the excimer laser-based techniques for low to moderate levels of astigmatism. Manual correction of the static cyclotorsion should be adopted for any SMILE astigmatic correction over 0.75 D. PMID- 29167809 TI - Short-term memory for spatial, sequential and duration information. AB - Space and time appear to play key roles in the way that information is organized in short-term memory (STM). Some argue that they are crucial contexts within which other stored features are embedded, allowing binding of information that belongs together within STM. Here we review recent behavioral, neurophysiological and imaging studies that have sought to investigate the nature of spatial, sequential and duration representations in STM, and how these might break down in disease. Findings from these studies point to an important role of the hippocampus and other medial temporal lobe structures in aspects of STM, challenging conventional accounts of involvement of these regions in only long term memory. PMID- 29167810 TI - The pre/parasubiculum: a hippocampal hub for scene-based cognition? AB - Internal representations of the world in the form of spatially coherent scenes have been linked with cognitive functions including episodic memory, navigation and imagining the future. In human neuroimaging studies, a specific hippocampal subregion, the pre/parasubiculum, is consistently engaged during scene-based cognition. Here we review recent evidence to consider why this might be the case. We note that the pre/parasubiculum is a primary target of the parieto-medial temporal processing pathway, it receives integrated information from foveal and peripheral visual inputs and it is contiguous with the retrosplenial cortex. We discuss why these factors might indicate that the pre/parasubiculum has privileged access to holistic representations of the environment and could be neuroanatomically determined to preferentially process scenes. PMID- 29167811 TI - Datasets, processing and refinement details for Mtb-AnPRT: inhibitor structures with various space groups. AB - There are twenty-five published structures of Mycobacterium tuberculosis anthranilate phosphoribosyltransferase (Mtb-AnPRT) that use the same crystallization protocol. The structures include protein complexed with natural and alternative substrates, protein:inhibitor complexes, and variants with mutations of substrate-binding residues. Amongst these are varying space groups (i.e. P21, C2, P21212, P212121). This article outlines experimental details for 3 additional Mtb-AnPRT:inhibitor structures. For one protein:inhibitor complex, two datasets are presented - one generated by crystallization of protein in the presence of the inhibitor and another where a protein crystal was soaked with the inhibitor. Automatic and manual processing of these datasets indicated the same space group for both datasets and thus indicate that the space group differences between structures of Mtb-AnPRT:ligand complexes are not related to the method used to introduce the ligand. PMID- 29167812 TI - Data for occupancy internal heat gain calculation in main building categories. AB - Heat losses from occupant body by means of convection, radiation, vapor, and sweat are essential data for indoor climate and energy simulations. Heat losses depend on the metabolic activity and body surface area. Higher variations of body surface area of occupants are observed in day care centers, kinder gardens and schools compared to other building categories (Tables 2 and 3) and these variations need to be accounted, otherwise in these building categories heat gains, CO2 and humidity generation are overestimated. Indoor temperature, humidity level, air velocity, and clothing insulation have significant influences on dry and total heat losses from occupant body leading to typical values for summer and winter. The data presented in this article are related to the research article entitled Occupancy schedules for energy simulation in new prEN16798-1 and ISO/FDIS 17772-1 standards (Ahmed et al., 2017) [1]. PMID- 29167813 TI - Experimental data on load test and performance parameters of a LENZ type vertical axis wind turbine in open environment condition. AB - Performance and load testing data of a three bladed two stage LENZ type vertical axis wind turbine from the experiments conducted in an open environment condition at Hindustan Institute of Technology and Science, Chennai (location 23.2167 degrees N, 72.6833 degrees E) are presented here. Low-wind velocity ranging from 2 to 11 m/s is available everywhere irrespective of climatic seasons and this data provides the support to the researchers using numerical tool to validate and develop an enhanced Lenz type design. Raw data obtained during the measurements are processed and presented in the form so as to compare with other typical outputs. The data is measured at different wind speeds prevalent in the open field condition ranging from 3 m/s to 9 m/s. PMID- 29167814 TI - Data for the optimization of conditions for meat species identification using ultra-fast multiplex direct-convection PCR. AB - This article contains data related to the research article entitled "Ultra-fast DNA-based multiplex convection PCR method for meat species identification with possible on-site applications" (Song et al., 2017 [1]). Direct PCR that does not require prior DNA extraction is critical for ultra-fast molecular detection of meat species. We successfully acquired DNA by swab sampling in Taq DNA polymerase buffer. To reduce DNA sample preparation time, proteinase K incubation (0.2 MUg/mL) and heat inactivation times were decreased to 10 min and 1 min, respectively. The analysis of swabbed DNA samples from mixed meat could differentiate meat species within the mixed sample. The swabbed DNA samples could be diluted 100 times without losing detection sensitivity. PMID- 29167815 TI - The metagenome of bromeliads phytotelma in Puerto Rico. AB - Bromeliads tank water or phytotelma is an eutrophic microenvironment where microorganisms have evolved to resist sudden changes in pH and nutritional competition. Metagenomics studies have been poorly studied in bromeliads and environmental DNA (eDNA) characterization for its microenvironment is deficient in Puerto Rico. Therefore, the data represents the microbial communities inhabiting bromeliads phytotelma. eDNA was extracted using Metagenomic DNA Isolation Kit for Water. Next-Generation-Sequencing technology (Illumina MiSeq) was used for sequencing the isolated eDNA. This data provides an insight about diversity and functional depiction of microorganisms inhabiting bromeliads phytotelma. The data of this metagenome is available in the BioSample Submission Portal as Bioproject PRJNA39461 and Sequence Read Archive (SRA) accession number SRP114300. MG-RAST metagenomic analysis server is located under the study ID mgp79812. PMID- 29167816 TI - Macroeconomic dataset for generating macroeconomic volatility among selected countries in the Asia Pacific region. AB - This data article provides macroeconomic data that can be used to generate macroeconomic volatility. The data cover a sample of seven selected countries in the Asia Pacific region for the period 2004-2014, including both developing and developed countries. This dataset was generated to enhance our understanding of the sources of macroeconomic volatility affecting the countries in this region. Although the Asia Pacific region continues to remain as the most dynamic part of the world's economy, it is not spared from various sources of macroeconomic volatility through the decades. The reported data cover 15 types of macroeconomic data series, representing three broad categories of indicators that can be used to proxy macroeconomic volatility. They are indicators that account for macroeconomic volatility (i.e. volatility as a macroeconomic outcome), domestic sources of macroeconomic volatility and external sources of macroeconomic volatility. In particular, the selected countries are Malaysia, Thailand, Indonesia and Philippines, which are regarded as developing countries, while Singapore, Japan and Australia are developed countries. Despite the differences in level of economic development, these countries were affected by similar sources of macroeconomic volatility such as the Asian Financial Crisis and the Global Financial Crisis. These countries were also affected by other similar external turbulence arising from factors such as the global economic slowdown, geopolitical risks in the Middle East and volatile commodity prices. Nonetheless, there were also sources of macroeconomic volatility which were peculiar to certain countries only. These were generally domestic sources of volatility such as political instability (for Thailand, Indonesia and Philippines), natural disasters and anomalous weather conditions (for Thailand, Indonesia, Philippines, Japan and Australia) and over-dependence on the electronic sector (for Singapore). PMID- 29167817 TI - Data on crystal organization in the structure of the Fab fragment from the NIST reference antibody, RM 8671. AB - The reported data describe the crystallization, crystal packing, structure determination and twinning of the unliganded Fab (antigen-binding fragment) from the NISTmAb (standard reference material 8671). The raw atomic coordinates are available as Protein Data Bank structure 5K8A and biological aspects are described in the article, (Karageorgos et al., 2017) [1]. Crystal data show that the packing is unique, and show the basis for the crystal's twinned growth. Twinning is a common and often serious problem in protein structure determination by x-ray crystallography [2]. In the present case the twinning is due to a small deviation (about 0.3 nm) from 4-fold symmetry in the primary intermolecular interface. The deviation produces pseudosymmetry, generating slightly different conformations of the protein, and alternating strong and weak forms of key packing interfaces throughout the lattice. PMID- 29167818 TI - A validation dataset for Macaque brain MRI segmentation. AB - Validation data for segmentation algorithms dedicated to preclinical images is fiercely lacking, especially when compared to the large number of databases of Human brain images and segmentations available to the academic community. Not only is such data essential for validating methods, it is also needed for objectively comparing concurrent algorithms and detect promising paths, as segmentation challenges have shown for clinical images. The dataset we present here is a first step in this direction. It comprises 10 T2-weighted MRIs of healthy adult macaque brains, acquired on a 7 T magnet, along with corresponding manual segmentations into 17 brain anatomic labelled regions spread over 5 hierarchical levels based on a previously published macaque atlas (Calabrese et al., 2015) [1]. By giving access to this unique dataset, we hope to provide a reference needed by the non-human primate imaging community. This dataset was used in an article presenting a new primate brain morphology analysis pipeline, Primatologist (Balbastre et al., 2017) [2]. Data is available through a NITRC repository (https://www.nitrc.org/projects/mircen_macset). PMID- 29167820 TI - Engineering Chimeric Antigen Receptor T cells to Treat Glioblastoma. AB - Immunotherapy has emerged as a promising strategy for glioblastoma (GBM), a disease that remains universally fatal despite currently available standard-of care. Adoptive T cell therapy has been shown to produce potent antitumor immunity while obviating the need for traditional antigen presentation and primary immune responses. Chimeric antigen receptors (CARs) are specialized molecules that can be expressed on the surface of T cells allowing for redirected cytotoxicity against tumor antigens of interest. To date, the application of CAR T cells for GBM has been relatively limited, in large part due to a dearth of well-described tumor specific antigens that are both homogenously and frequently expressed. A mutated version of the epidermal growth factor receptor, EGFRvIII, is a constitutively activated tyrosine kinase that is expressed on the surface of GBM and other common neoplasms, but completely absent from all normal tissues. We have recently generated CAR T cells directed against EGFRvIII and reported results from a Phase I clinical trial investigating this platform in patients with EGFRvIII-expressing GBM. Our study showed that despite conventional notions of central nervous system "immune-privilege," EGFRvIII CAR T cells trafficked to intracerebral tumors, leading to successful targeting and eradication of this antigen in the brain. Here, we review our experience with EGFRvIII CAR T cells and highlight important considerations for the clinical translation of this therapy in patients with GBM. PMID- 29167819 TI - Successful amplification of DNA aboard the International Space Station. AB - As the range and duration of human ventures into space increase, it becomes imperative that we understand the effects of the cosmic environment on astronaut health. Molecular technologies now widely used in research and medicine will need to become available in space to ensure appropriate care of astronauts. The polymerase chain reaction (PCR) is the gold standard for DNA analysis, yet its potential for use on-orbit remains under-explored. We describe DNA amplification aboard the International Space Station (ISS) through the use of a miniaturized miniPCR system. Target sequences in plasmid, zebrafish genomic DNA, and bisulfite treated DNA were successfully amplified under a variety of conditions. Methylation-specific primers differentially amplified bisulfite-treated samples as would be expected under standard laboratory conditions. Our findings establish proof of concept for targeted detection of DNA sequences during spaceflight and lay a foundation for future uses ranging from environmental monitoring to on orbit diagnostics. PMID- 29167821 TI - PTK6 regulates growth and survival of endocrine therapy-resistant ER+ breast cancer cells. AB - The non-receptor tyrosine kinase, PTK6/BRK, is highly expressed in multiple tumor types, including prostate, ovarian, and breast cancers, and regulates oncogenic phenotypes such as proliferation, migration, and survival. PTK6 inhibition also overcomes targeted therapy resistance of HER2+ breast cancer. Although PTK6 is highly expressed in ER+ Luminal breast cancers, the role of PTK6 in this subtype has not been elucidated. In this study, we investigated the functions of PTK6 in ER+ Luminal breast cancer cells, including those that are relatively resistant to estrogen deprivation or targeted endocrine therapies used in the treatment of ER+ cancers. Enhanced expression of PTK6 in ER+ breast cancer cells enhances growth of ER+ breast cancer cells, including tamoxifen-treated cells. Downregulation of PTK6 in ER+ breast cancer cells, including those resistant to tamoxifen, fulvestrant, and estrogen deprivation, induces apoptosis, as evidenced by increased levels of cleaved PARP, and an increase in the AnnexinV+ population. PTK6 downregulation impairs growth of these cells in 3D MatrigelTM cultures, and virtually abrogates primary tumor growth of both tamoxifen-sensitive and resistant MCF-7 xenografts. Finally, we show that p38 MAPK activation is critical for PTK6 downregulation-induced apoptosis, a mechanism that we previously reported for survival of HER2+ breast cancer cells, highlighting conserved mechanisms of survival regulation by PTK6 across breast cancer subtypes. In conclusion, our studies elucidate critical functions of PTK6 in ER+ Luminal breast cancers and support PTK6 as an attractive therapeutic target for ER+ breast cancers. PMID- 29167822 TI - Two-dimensional limit of crystalline order in perovskite membrane films. AB - Long-range order and phase transitions in two-dimensional (2D) systems-such as magnetism, superconductivity, and crystallinity-have been important research topics for decades. The issue of 2D crystalline order has reemerged recently, with the development of exfoliated atomic crystals. Understanding the dimensional limit of crystalline phases, with different types of bonding and synthetic techniques, is at the foundation of low-dimensional materials design. We study ultrathin membranes of SrTiO3, an archetypal perovskite oxide with isotropic (3D) bonding. Atomically controlled membranes are released after synthesis by dissolving an underlying epitaxial layer. Although all unreleased films are initially single-crystalline, the SrTiO3 membrane lattice collapses below a critical thickness (5 unit cells). This crossover from algebraic to exponential decay of the crystalline coherence length is analogous to the 2D topological Berezinskii-Kosterlitz-Thouless (BKT) transition. The transition is likely driven by chemical bond breaking at the 2D layer-3D bulk interface, defining an effective dimensional phase boundary for coherent crystalline lattices. PMID- 29167823 TI - Apelin Gene Therapy Increases Autophagy via Activation of Sirtuin 3 in Diabetic Heart. AB - Heart failure is the leading cause of death in diabetic patients. Recently we showed that apelin gene therapy attenuates heart failure following myocardial infarction. This study further explored the potential mechanisms by which apelin may reduce cardiac injury in Postmyocardial infarction (MI)) model of diabetes. Wild type and Sirt3 knockout (Sirt3 KO) mice were induced into diabetes by intra peritoneal (i.p.) Streptozotocin (STZ). STZ mice were then subjected to MI followed by immediate intramyocardial injection with Adenovirus-apelin (Ad apelin). Ad-apelin treatment resulted in over expression of apelin in the ischemic hearts of STZ mice. Apelin over expression led to a significant increase in Sirt3 expression. Apelin over expression significantly reduced gp91phox expression. This was accompanied by a significant reduction of reactive oxygen species formation. Ad-apelin treatment also dramatically reduced NF-kappab-p65 expression in WT-STZ mice. Over expression of apelin further enhanced autophagy markers (LC3-II and beclin-1) expression in post-MI heart. Most intriguingly, knockout of Sirt3 in STZ mice abolished these beneficial effects of apelin treatment. In vitro, knockout of Sirt3 in EPCs significantly enhanced high glucose-induced ROS formation. Conversely, treatment of Sirt3 KO-EPCs with NADPH oxidase inhibitor led to two fold increase in LC3-II levels. Our studies demonstrate that apelin increases autophagy via up regulation of Sirt3 and suppression of ROS-NF-kappab pathway in diabetic heart. PMID- 29167824 TI - Protein activation mapping of human sun-protected epidermis after an acute dose of erythemic solar simulated light. AB - Ultraviolet radiation is an important etiologic factor in skin cancer and a better understanding of how solar stimulated light (SSL) affects signal transduction pathways in human skin which is needed in further understanding activated networks that could be targeted for skin cancer prevention. We utilized Reverse Phase Protein Microarray Analysis (RPPA), a powerful technology that allows for broad-scale and quantitative measurement of the activation/phosphorylation state of hundreds of key signaling proteins and protein pathways in sun-protected skin after an acute dose of two minimal erythema dose (MED) of SSL. RPPA analysis was used to map the altered cell signaling networks resulting from acute doses of solar simulated radiation (SSL). To that end, we exposed sun-protected skin in volunteers to acute doses of two MED of SSL and collected biopsies pre-SSL and post-SSL irradiation. Frozen biopsies were subjected to laser capture microdissection (LCM) and then assessed by RPPA. The activation/phosphorylation or total levels of 128 key signaling proteins and drug targets were selected for statistical analysis. Coordinate network-based analysis was performed on specific signaling pathways that included the PI3k/Akt/mTOR and Ras/Raf/MEK/ERK pathways. Overall, we found early and sustained activation of the PI3K-AKT-mTOR and MAPK pathways. Cell death and apoptosis-related proteins were activated at 5 and 24 h. Ultimately, expression profile patterns of phosphorylated proteins in the epidermal growth factor receptor (EGFR), AKT, mTOR, and other relevant pathways may be used to determine pharmacodynamic activity of new and selective topical chemoprevention agents administered in a test area exposed to SSL to determine drug-induced attenuation or reversal of skin carcinogenesis pathways. PMID- 29167825 TI - An epidemiological survey of porcine cysticercosis in Nyasa District, Ruvuma Region, Tanzania. AB - Porcine cysticercosis (PC) caused by Taenia solium larvae is continuing being important zoonotic disease in many developing countries. It poses a serious public health risk and leads to economic losses to pig production industry. This study was carried out to determine the prevalence and risk factors associated with PC transmission in Nyasa District. To establish the prevalence of PC, a cross-sectional survey was conducted involving 698 pigs by tongue examination, 330 pigs by Ag-ELISA test and 22 pigs by meat inspection. A questionnaire survey was administered to a member of selected households to gather information on pig management and other potential factors that could explain the prevalence of PC in the area. Results showed that 44 pigs were positive by tongue examination (6.3%, 95% C.I. 4.5-8.1%), 110 tested positive for Ag-ELISA (33.3%, 95% C.I. 28.22 38.38%) and meat inspection detected four infected pigs (18.2%, 95% C.I. 2.08 34.32%). Risk factors associated with PC transmission in Nyasa District were free ranging of pigs (p = 0001), sex of pig (p = 0.011), source of pork (p = 0.0001) and outdoor defecation (0.0001). The present findings indicate that PC is endemic in Nyasa District and that free-ranging of pigs in conjunction with limited use of latrines contributes significantly to PC transmission. Therefore, mandatory pig confinement, together with use of latrine/toilets should be considered in controlling PC in Nyasa District. PMID- 29167826 TI - Efficient in vitro delivery of Noggin siRNA enhances osteoblastogenesis. AB - Several types of serious bone defects would not heal without invasive clinical intervention. One approach to such defects is to enhance the capacity of bone formation cells. Exogenous bone morphogenetic proteins (BMP) have been utilized to positively regulate matrix mineralization and osteoblastogenesis, however, numerous adverse effects are associated with this approach. Noggin, a potent antagonist of BMPs, is an ideal candidate to target and decrease the need for supraphysiological doses of BMPs. In the current research we report a novel siRNA mediated gene knock-down strategy to down-regulate Noggin. We utilized a lipid nanoparticle (LNP) delivery strategy in pre-osteoblastic rat cells. In vitro LNP siRNA treatment caused inconsequential cell toxicity and transfection was achieved in over 85% of cells. Noggin siRNA treatment successfully down-regulated cellular Noggin protein levels and enhanced BMP signal activity which in turn resulted in significantly increased osteoblast differentiation and extracellular matrix mineralization evidenced by histological assessments. Gene expression analysis showed that targeting Noggin specifically in bone cells would not lead to a compensatory effect from other BMP negative regulators such as Gremlin and Chordin. The results from this study support the notion that novel therapeutics targeting Noggin have the clinically relevant potential to enhance bone formation without the need for toxic doses of exogenous BMPs.

PMID- 29167827 TI - Hepatocellular cancer and recurrence after liver transplantation: what about the impact of immunosuppression? AB - Liver transplantation (LT) has originally been designed to treat hepatobiliary malignancies. The initial results of LT for hepatocellular cancer (HCC) were, however, dismal this mainly due to the poor patient selection procedure. Better surgical and perioperative care and, especially, the refinement of selection criteria led to a major improvement of results, making HCC nowadays (again!) one of the leading indications for LT. This evolution is clearly shown by the innumerable reports aiming to further extend inclusion criteria for LT in HCC patients. Nonetheless, the vast majority of papers only deals with morphologic (tumour diameter and number) and (only recently) biologic (tumour markers and response to locoregional treatment) parameters to do so. Curiously enough, the role of both the immune competent state of the recipient as well as the impact of both immunosuppression (IS) type and load has been very poorly addressed in this context, even if it has been shown for a long time, based on both basic and clinical research, that they all play a key role in the outcome of any oncologic treatment and in the development of de novo as well as recurrent tumours. This chapter aims to give, after a short introductive note about the currently used inclusion criteria of HCC patients for LT and about the role of IS in carcinogenesis, a comprehensive overview of the actual literature related to the impact of different immunosuppressive drugs and schemes on outcome of LT in HCC recipients. Unfortunately, up to now solid conclusions cannot be drawn due to the lack of high-level evidence studies caused by the heterogeneity of the studied patient cohorts and the lack of prospectively designed and randomized studies. Based on long-term personal experience with immunosuppressive handling in LT some proposals for further clinical research and practice are put forward. The strategy of curtailing and minimising IS should be explored in the growing field of transplant oncology taking thereby into account the immunological privilege of the liver allograft. These strategies will become more and more compelling when further extending the indications in which adjuvant chemotherapy will probably become an inherent part of the therapeutic scheme of HCC liver recipients. PMID- 29167830 TI - Single injection dual phase CBCT technique ameliorates results of trans-arterial chemoembolization for hepatocellular cancer. AB - Cone-beam CT (CBCT) application to the field of trans-arterial chemoembolization has been recently the focus of several researches. This imaging modality is performed with a rotation of the C-arm around the patient, without needs of patient repositioning. Datasets are immediately processed, obtaining volumetric CT-like images with the possibility of post-processing and reconstruction of images. Dual phase CBCT recently introduced in clinical practice consists in a first arterial acquisition followed by a delayed acquisition corresponding to a venous phase. The introduction of this feature has overcome the limit of single phase acquisitions, allowing lesions characterization. Moreover these recent advantages have several intra-procedural implications. Detailed technical and acquisition parameters will be widely exposed in this review with particular attention to: catheter positioning, acquisition delay, injection parameters, patient positioning and contrast dilution. Comparison with standard of practice second line imaging [multidetector computer tomography (MDCT) and MDCT/arteriography] demonstrate the capability of detecting occult nodules providing some clinical implications thus potentially identifying a sub set of patients with aggressive disease behaviour. Other intra-procedural advantages of dual phase CBCT usage consist in a better tumor feeder visualization, reduction of proper DSA and fluoroscopic time, suggestion the presence of an extrahepatic parasitic feeder thus resulting in a more accurate treatment. Finally, the volumetrical intraprocedural evaluation of accumulation of embolic agent has proved to be correlate with treatment response if compared with MRI. PMID- 29167831 TI - Laparoscopic distal gastrectomy with D2 lymphadenectomy followed by intracorporeal gastroduodenostomy for advanced gastric cancer: technical guide and tips. AB - In 1994, Kitano and colleagues first reported laparoscopy-assisted Billroth I gastrectomy. Since then, laparoscopic gastrectomy (LG) has been associated with earlier patient recovery compared with open surgery, and has gained increasing international acceptance. Japan Society of Endoscopic Surgery biennial surveys confirm the increasing use of laparoscopic procedures for treatment of gastric cancer in Japan. Its thirteenth national survey indicates that of 31,264 patients treated at Japanese institutions in 2015, approximately 9,500 (30.3%) underwent LG, and laparoscopic distal gastrectomy (LDG) was the procedure most commonly performed. Despite evidence supporting the efficacy of LDG for gastric cancer in the short term, however, uncertainty remains concerning the efficacy of LG. Today, phase III randomized control trials on this procedure are ongoing in East Asian countries. Distal gastrectomy (DG) is the most commonly performed mode of resection, and as appropriate surgical techniques need to be acquired by gastric surgeons, here we describe a 'gold standard' method to perform total LDG. PMID- 29167832 TI - Assessment of nutritional status in laparoscopic gastrectomy for gastric cancer. AB - Malnutrition is very common in gastric cancer patients and can be detected in up to 85% of patients with gastric cancer. Malnutrition is associated with increased morbidity and mortality, prolonged hospital stay, poor treatment tolerance, and lower survival rate. Malnutrition also has an impact on quality of life. The early detection of nutritional risk with appropriate nutritional care can significantly reduce patient's postoperative morbidity and mortality. Because there is no gold standard tool, appropriate tools should be selected and applied depending on one's institutional conditions. And, it is recommended that nutritional assessment should be achieved for every patient at pre/post-operative period. PMID- 29167833 TI - Disorder-Specific and Shared Brain Abnormalities During Vigilance in Autism and Obsessive-Compulsive Disorder. AB - Background: Autism spectrum disorder (ASD) and obsessive-compulsive disorder (OCD) are often comorbid and share similarities across some cognitive phenotypes, including certain aspects of attention. However, no functional magnetic resonance imaging studies have compared the underlying neural mechanisms contributing to these shared phenotypes. Methods: Age- and IQ-matched boys (11-17 years old) with ASD (n = 20), boys with OCD (n = 20), and healthy control boys (n = 20) performed a parametrically modulated psychomotor vigilance functional magnetic resonance imaging task. Brain activation and performance were compared among adolescents with OCD, adolescents with ASD, and control adolescents. Results: Whereas boys with ASD and OCD were not impaired on task performance, there was a significant group by attention load interaction in several brain regions. With increasing attention load, left inferior frontal cortex/insula and left inferior parietal lobe/pre/post-central gyrus were progressively less activated in boys with OCD relative to the other two groups. In addition, boys with OCD showed progressively increased activation with increasing attention load in rostromedial prefrontal/anterior cingulate cortex relative to boys with ASD and control boys. Shared neurofunctional abnormalities between boys with ASD and boys with OCD included increased activation with increasing attention load in cerebellum and occipital regions, possibly reflecting increased default mode network activation. Conclusions: This first functional magnetic resonance imaging study to compare boys with ASD and OCD showed shared abnormalities in posterior cerebellar occipital brain regions. However, boys with OCD showed a disorder-specific pattern of reduced activation in left inferior frontal and temporo-parietal regions but increased activation of medial frontal regions, which may potentially be related to neurobiological mechanisms underlying cognitive and clinical phenotypes of OCD. PMID- 29167834 TI - Hypoactivation and Dysconnectivity of a Frontostriatal Circuit During Goal Directed Planning as an Endophenotype for Obsessive-Compulsive Disorder. AB - Background: The symptoms of obsessive-compulsive disorder (OCD) have been postulated to result from impaired executive functioning and excessive habit formation at the expense of goal-directed control and have been objectively demonstrated using neuropsychological tests in such patients. This study tested whether there is functional hypoactivation as well as dysconnectivity of discrete frontostriatal pathways during goal-directed planning in patients with OCD and in their unaffected first-degree relatives. Methods: In total, 21 comorbidity-free patients with OCD, 19 clinically asymptomatic first-degree relatives of these patients, and 20 control participants were tested on a functional magnetic resonance optimized version of the Tower of London task. Group differences in brain activation during goal-directed planning were measured together with associated frontostriatal functional connectivity. Results: Patients with OCD and their clinically asymptomatic relatives manifested hypoactivation of the right dorsolateral prefrontal cortex during goal-directed planning coupled with reduced functional connectivity between this cortical region and the basal ganglia (putamen). Conclusions: Hypoactivation of cortical regions associated with goal directed planning and associated frontostriatal dysconnectivity represent a candidate endophenotype for OCD. These findings accord with abnormalities in neural networks supporting the balance between goal-directed and habitual behavior, with implications for recent neuropsychological theories of OCD and the major neurobiological model for this disorder. PMID- 29167835 TI - Sensitizing Clostridium difficile Spores with Germinants on Skin and Environmental Surfaces Represents a New Strategy for Reducing Spores via Ambient Mechanisms. AB - Background: Clostridium difficile is a leading cause of healthcare-associated infections worldwide. Prevention of C. difficile transmission is challenging because spores are not killed by alcohol-based hand sanitizers or many commonly used disinfectants. One strategy to control spores is to induce germination, thereby rendering the spores more susceptible to benign disinfection measures and ambient stressors. Methods/Results: C. difficile spores germinated on skin after a single application of cholic acid-class bile salts and co-germinants; for 4 C. difficile strains, recovery of viable spores from skin was reduced by ~0.3 log10CFU to 2 log10CFU after 2 hours and ~1 log10CFU to > 2.5 log10CFU after 24 hours. The addition of taurocholic acid to 70% and 30% ethanol significantly enhanced reduction of viable spores on skin and on surfaces. Desiccation, and to a lesser extent the presence of oxygen, were identified as the stressors responsible for reductions of germinated spores on skin and surfaces. Additionally, germinated spores became susceptible to killing by pH 1.5 hydrochloric acid, suggesting that germinated spores that remain viable on skin and surfaces might be killed by gastric acid after ingestion. Antibiotic-treated mice did not become colonized after exposure to germinated spores, whereas 100% of mice became colonized after exposure to the same quantity of dormant spores. Conclusions: Germination could provide a new approach to reduce C. difficile spores on skin and in the environment and to render surviving spores less capable of causing infection. Our findings suggest that it may be feasible to develop alcohol-based hand sanitizers containing germinants that reduce spores on hands. PMID- 29167836 TI - Optical spin transfer and spin-orbit torques in thin film ferromagnets. AB - We study the optically induced torques in thin film ferromagnetic layers under excitation by circularly polarized light. We study cases both with and without Rashba spin-orbit coupling using a 4-band model. In the absence of Rashba spin orbit coupling, we derive an analytic expression for the optical torques, revealing the conditions under which the torque is mostly derived from optical spin transfer torque (i.e. when the torque is along the direction of optical angular momentum), versus when the torque is derived from the inverse Faraday effect (i.e. when the torque is perpendicular to the optical angular momentum). We find the optical spin transfer torque dominates provided that the excitation energy is far away from band edge transitions, and the magnetic exchange splitting is much greater than the lifetime broadening. For the case with large Rashba spin-orbit coupling and out-of-plane magnetization, we find the torque is generally perpendicular to the photon angular momentum and is ascribed to an optical Edelstein effect. PMID- 29167837 TI - Neighborhood and Individual Sociodemographic Characteristics Associated with Disparities in Adult Obesity and Perceptions of the Home Food Environment. AB - Purpose: Multiple studies have demonstrated significant disparities in the relationship between individual sociodemographic characteristics and risk of overweight or obesity. However, little information is available for assessing the complex associations among being overweight or obese with neighborhood and individual sociodemographic factors and the measured and perceived community food environment. Methods: Using 2014 national evaluation data from 20 communities (analyzed 2015-2016) that participated in the U.S. Centers for Disease Control and Prevention Community Transformation Grants Program, we used multilevel multivariable models to assess associations among factors at the individual, census tract, and county levels with being overweight or obese and with the perceived home food environment. Results: Individual level factors (age, sex, race/ethnicity, household income, and education) were significantly associated with the likelihood of being overweight or obese in every model tested. Census tract level poverty and education were significantly associated with the likelihood of being overweight or obese in univariate but not multivariable analyses. Perceived community food environment was a significant predictor of the perceived home food environment; the objective measure of county-level grocery store access was not. Neither perceived nor objective community food environment measures were significantly associated with overweight/obesity in multivariable analyses. Conclusion: Individual-level sociodemographic characteristics are more strongly associated with obesity-related outcomes than are area-level measures. Future interventions designed to address health equity issues in obesity among underserved populations may benefit from focusing on nutrition education tailored to individuals, to encourage purchase and consumption of healthy food. Improving healthy food availability in underserved communities may also be critical for nutrition education to have a meaningful impact.

PMID- 29167839 TI - Early-life exposure to indoor air pollution or tobacco smoke and lower respiratory tract illness and wheezing in African infants: a longitudinal birth cohort study. AB - Background: Indoor air pollution (IAP) and environmental tobacco smoke (ETS) are associated with lower respiratory tract illness (LRTI) or wheezing in children. However, the effect of the timing of these exposures, specifically antenatal versus postnatal, and of alternate fuel sources such as the increasingly used volatile organic compounds have not been well studied. We longitudinally investigated the effect of antenatal or postnatal IAP and ETS on LRTI or wheezing prevalence and severity in African infants. Methods: Mother and infant pairs enrolled over a 3-year period in a birth cohort study in two centres in Paarl, South Africa, were followed for the first year of life for LRTI or wheezing illness. We measured exposure to IAP (particulate matter, nitrogen dioxide, sulphur dioxide, carbon monoxide, and volatile organic compounds benzene and toluene) using devices placed in homes, antenatally and postnatally. We measured ETS longitudinally by maternal self-report and by urine cotinine measures. Study staff trained in recognition of LRTI or wheeze documented all episodes, which were categorised according to WHO case definition criteria. We used multivariate logistic and Poisson regressions to explore associations. Findings: Between March 1, 2012, and March 31, 2015, we enrolled 1137 mothers with 1143 livebirths. Of 1065 infants who attended at least one study visit, 524 episodes of LRTI occurred after discharge with a wheezing prevalence of 0.23 (95% CI 0.21-0.26) episodes per child year. Exposures associated with LRTI were antenatal maternal smoking (incidence rate ratio 1.62, 95% CI 1.14-2.30; p=0.004) or particulate matter (1.43, 1.06-1.95; p=0.008). Subanalyses of LRTI requiring hospitalisation (n=137) and supplemental oxygen (n=69) found antenatal toluene significantly increased the risk of LRTI-associated hospitalisation (odds ratio 5.13, 95% CI 1.43-18.36; p=0.012) and need for supplemental oxygen (13.21, 1.96-89.16; p=0.008). Wheezing illness was associated with both antenatal (incidence rate ratio 2.09, 95% CI 1.54-2.84; p<0.0001) and postnatal (1.27, 95% CI 1.03-1.56; p=0.024) maternal smoking. Antenatally, wheezing was associated with maternal passive smoke exposure (1.70, 1.25-2.31; p=0.001) and, postnatally, with any household member smoking (1.55, 1.17 -2.06; p=0.002). Interpretation: Antenatal exposures were the predominant risk factors associated with LRTI or wheezing illness. Toluene was a novel exposure associated with severe LRTI. Urgent and effective interventions focusing on antenatal environmental factors are required, including smoking cessation programmes targeting women of childbearing age pre-conception and pregnant women.

PMID- 29167840 TI - Intracranial Volume Quantification from 3D Photography. AB - 3D photography offers non-invasive, radiation-free, and anesthetic-free evaluation of craniofacial morphology. However, intracranial volume (ICV) quantification is not possible with current non-invasive imaging systems in order to evaluate brain development in children with cranial pathology. The aim of this study is to develop an automated, radiation-free framework to estimate ICV. Pairs of computed tomography (CT) images and 3D photographs were aligned using registration. We used the real ICV calculated from the CTs and the head volumes from their corresponding 3D photographs to create a regression model. Then, a template 3D photograph was selected as a reference from the data, and a set of landmarks defining the cranial vault were detected automatically on that template. Given the 3D photograph of a new patient, it was registered to the template to estimate the cranial vault area. After obtaining the head volume, the regression model was then used to estimate the ICV. Experiments showed that our volume regression model predicted ICV from head volumes with an average error of 5.81 +/- 3.07% and a correlation (R2) of 0.96. We also demonstrated that our automated framework quantified ICV from 3D photography with an average error of 7.02 +/- 7.76%, a correlation (R2) of 0.94, and an average estimation error for the position of the cranial base landmarks of 11.39 +/- 4.3mm.

PMID- 29167844 TI - Recellularization of decellularized adipose tissue-derived stem cells: role of the cell-secreted extracellular matrix in cellular differentiation. AB - Adipose-derived stem cells (ASCs) are found in a location within the adipose tissue known as the stem cell niche. The ASCs in the niche are maintained in the quiescent state, and upon exposure to various microenvironmental triggers are prompted to undergo proliferation or differentiation. These microenvironmental triggers also modulate the extracellular matrix (ECM), which interacts with the cells through the cytoskeleton and induces downstream events inside the cells that bring about a change in cell behaviour. In response to these changes, the cells remodel the ECM, which will differ according to the type of tissue being formed by the cells. As the ECM itself plays an important role in the regulation of cellular differentiation, this study aims to explore the role of the cell secreted ECM at various stages of differentiation of stem cells in triggering the differentiation of ASCs. To this end, the ASCs cultured in proliferation, osteogenic and adipogenic media were decellularized and the secreted ECM was characterized. Overall, it was found that osteo-differentiated ASCs produced higher amounts of collagen and glycosaminoglycans (GAG) compared to the undifferentiated and adipo-differentiated ASCs. The two types of differentiated ECMs were subsequently shown to trigger initial but not terminal differentiation of ASCs into osteo- and adipo-lineages respectively, as indicated by the upregulation of lineage specific markers. In addition, integrin subunits alpha (alpha) 6 and integrin beta (beta) 1 were found to be produced by ASCs cultured on cell-secreted ECM-coated substrates, suggesting that the integrins alpha6 and beta1 play an instrumental role in cell-ECM interactions. Taken together, this study demonstrates the importance of the ECM in cellular fate decisions and how ECM-coated substrates can potentially be used for various tissue engineering applications.

PMID- 29167847 TI - Fluorescent nanoparticles from mature vinegar: their properties and interaction with dopamine. AB - Naturally occurring nanoparticles may be present in food. In this paper we report the discovery of fluorescent nanoparticles (FNs) in Chinese mature vinegar. The physicochemical properties of these FNs were investigated. The FNs were shown to emit bright blue fluorescence under the irradiation of ultraviolet light, with a fluorescence quantum yield of 5.71%. They are highly soluble in aqueous solution, and exhibit excitation-dependent emission behavior. TEM characterization showed that the average size of FNs is about 1.40 +/- 0.40 nm, and the morphology of FNs is mainly spherical. The physicochemical properties of FNs are similar to those of artificially synthesized carbon dots. Furthermore, the interaction between FNs and dopamine was studied, and the fluorescence of FNs varied gradually from a blue, to a cyan and finally to a green color with increasing dopamine concentration. The fluorescence decay dynamics revealed that Forster resonance energy transfer (FRET) occurred between the FNs and polymerized dopamine. This result suggests that the FNs from Chinese mature vinegar can interact with dopamine, which may add a new perspective to the potential health implications of foodborne nanoparticles.

AB - A silver catalyzed decarboxylative C(sp2)-C(sp3) coupling of vinylic carboxylic acids with alcohols, alkylbenzenes, cycloalkanes and cyclic ethers was developed by using DTBP as an oxidant. This reaction tolerates a wide range of substrates, and products are obtained in good to excellent yields. The reaction also shows good stereoselectivity, and only trans-isomers are obtained. In addition, a radical pathway would be involved to facilitate this decarboxylative C(sp2) C(sp3) coupling reaction. PMID- 29167849 TI - Identifying DNA mismatches at single-nucleotide resolution by probing individual surface potentials of DNA-capped nanoparticles. AB - Here, we demonstrate a powerful method to discriminate DNA mismatches at single nucleotide resolution from 0 to 5 mismatches (chi0 to chi5) using Kelvin probe force microscopy (KPFM). Using our previously developed method, we quantified the surface potentials (SPs) of individual DNA-capped nanoparticles (DCNPs, ~100 nm). On each DCNP, DNA hybridization occurs between ~2200 immobilized probe DNA (pDNA) and target DNA with mismatches (tDNA, ~80 nM). Thus, each DCNP used in the bioassay (each pDNA-tDNA interaction) corresponds to a single ensemble in which a large number of pDNA-tDNA interactions take place. Moreover, one KPFM image can scan at least dozens of ensembles, which allows statistical analysis (i.e., an ensemble average) of many bioassay cases (ensembles) under the same conditions. We found that as the chin increased from chi0 to chi5 in the tDNA, the average SP of dozens of ensembles (DCNPs) was attenuated owing to fewer hybridization events between the pDNA and the tDNA. Remarkably, the SP attenuation vs. the chin showed an inverse-linear correlation, albeit the equilibrium constant for DNA hybridization exponentially decreased asymptotically as the chin increased. In addition, we observed a cascade reaction at a 100-fold lower concentration of tDNA (~0.8 nM); the average SP of DCNPs exhibited no significant decrease but rather split into two separate states (no-hybridization vs. full-hybridization). Compared to complementary tDNA (i.e., chi0), the ratio of no-hybridization/full hybridization within a given set of DCNPs became ~1.6 times higher in the presence of tDNA with single mismatches (i.e., chi1). The results imply that our method opens new avenues not only in the research on the DNA hybridization mechanism in the presence of DNA mismatches but also in the development of a robust technology for DNA mismatch detection. PMID- 29167851 TI - What regulates the catalytic activities in AGE catalysis? An answer from quantum mechanics/molecular mechanics simulations. AB - The AGE superfamily (AGEs) is made up of kinds of isomerase which are very important both physiologically and industrially. One of the most intriguing aspects of AGEs has to do with the mechanism that regulates their activities in single conserved active pocket. In order to clarify the relationship among single conserved active pocket and two activities in AGEs, results for the epimerization activity catalyzed by RaCE and the isomerization activity catalyzed by SeYihS were obtained by using QM/MM umbrella sampling simulations and 2D-FES calculations. Our results show that both of them have similar enzyme-substrate combination mode for inner pyranose ring in single conserved active pocket even though they have different substrate specificity. This means that the pathways of ring opening catalyzed by them are similar. However, one non-conserved residue (Leu183 in RaCE, Met175 in SeYihS) in the active site, which has different steric hindrance, causes a small but effective change in the direction of ring opening in stage 1. And then this change will induce a fundamentally different catalytic activity for RaCE and SeYihS in stage 2. Our results give a novel viewpoint about the regulatory mechanism between CE and YihS in AGEs, and may be helpful for further experiments of rational enzyme design based on the (alpha/alpha)6-barrel basic scaffold.

AB - Styrylisoxazoles bearing a nitro group linked to bulky aromatic rings have been synthesized and examined for their absorption and emission studies in organic solvents and water. The molecules showed emission in the visible region with significant solvatochromic emission shifts influenced by the extended conjugation of aromatic rings and intramolecular charge transfer. These absorption and emission changes were used for the efficient and sensitive detection of trace concentrations of hydrogen sulfide (H2S) through the reduction of the nitro group to the amine group in the presence of aqueous sodium sulfide. The experimental results indicated that the probes exhibit an excellent emission response with large shifts in the emission and sensitivity with a micromolar detection limit. PMID- 29167854 TI - Nitrate-assisted photocatalytic efficiency of defective Eu-doped Pr(OH)3 nanostructures. AB - Pr(OH)3 one-dimensional nanostructures are a less studied member of lanthanide hydroxide nanostructures, which recently demonstrated an excellent adsorption capacity for organic pollutant removal from wastewater. In this study, Pr1 xEux(OH)3 (x = 0, 0.01, 0.03, and 0.05) defective nanostructures were synthesized by a facile and scalable microwave-assisted hydrothermal method using KOH as an alkaline metal precursor. The phase and surface composition, morphology, vibrational, electronic and optical properties of the as-prepared samples were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), inductively coupled plasma optical emission spectrometry (ICP-OES), transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), Raman, infrared (IR), photoluminescence (PL), and diffuse reflectance spectroscopy (DRS). It was deduced that the incorporation of Eu3+ ions promoted the formation of oxygen vacancies in the already defective Pr(OH)3, subsequently changing the Pr(OH)3 nanorod morphology. The presence of KNO3 phase was registered in the Eu-doped samples. The oxygen-deficient Eu-doped Pr(OH)3 nanostructures displayed an improved photocatalytic activity in the removal of reactive orange (RO16) dye under UV-vis light irradiation. An enhanced photocatalytic activity of the Eu-doped Pr(OH)3 nanostructures was caused by the synergetic effect of oxygen vacancies and Eu3+ (NO3-) ions present on the Pr(OH)3 surface, the charge separation efficiency and the formation of the reactive radicals. In addition, the 3% Eu-doped sample exhibited very good adsorptive properties due to different morphology and higher electrostatic attraction with the anionic dye. Pr1-xEux(OH)3 nanostructures with the possibility of tuning their adsorption/photocatalytic properties present a great potential for wastewater treatment. PMID- 29167857 TI - Vesicle to micelle transition in the ternary mixture of L121/SDS/D2O: NMR, EPR and SANS studies. AB - Subtle changes in the microstructure and dynamics of the triblock copolymer L121, (ethylene oxide)5 (propylene oxide)68 (ethylene oxide)5i.e., E5P68E5, and sodium dodecylsulfate (SDS) system in aqueous medium were investigated using high resolution nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR) and small-angle neutron scattering (SANS) methods. NMR self-diffusion measurements helped us to understand the nature of binding of SDS with L121, and the formation of their mixed aggregates. These results showed that even at low [SDS] (~2 mM), the addition of L121 stabilized the dynamics of SDS. Furthermore, the increase in [SDS] resulted in progressive changes in the diffusion behavior of both SDS and L121. 13C chemical shift analysis revealed that preferential binding of L121 occurred on the SDS micelle surface. Deuterium (2H) NMR spin relaxation data evidenced that the formed mixed aggregates were non-spherical in terms of relaxation rate changes, and slowed the dynamics. The rotational correlation times of mixed aggregates were estimated from EPR analysis. A SANS study indicated the presence of uni- and multi-lamellar vesicles of L121 at low [SDS]. The vesicles transformed to mixed L121-SDS micelles in the presence of a higher [SDS]. This was supported by the measurements of 2H NMR spin-relaxation and EPR rotational correlation times. PMID- 29167858 TI - Cutaneous Squamous Cell Carcinomas in Solid Organ Transplant Recipients Compared With Immunocompetent Patients. AB - Importance: Solid organ transplant recipients (SOTRs) have a 100-fold increased risk of squamous cell carcinoma (SCC), and they may develop more aggressive SCCs compared with immunocompetent individuals. Objective: To compare outcomes associated with aggressive behavior of SCC in SOTRs and high-risk immunocompetent patients. Design, Setting, and Participants: A retrospective cohort study of 58 SOTRs and 40 immunocompetent patients evaluated at the Yale Transplant Dermatology Clinic in New Haven, Connecticut, who had at least 1 SCC confirmed histopathologically between January 1, 2008, and December 31, 2015. Cumulative follow-up time for this study was 369 patient-years. Exposure: Immunosuppressive medication regimen for SOTRs. Main Outcomes and Measures: The primary outcome measure was tumor depth of SCC. Secondary outcome measures that reflected tumor aggressiveness included perineural invasion, regional metastases, nodal metastases, disease-specific death, and overall death. Results: Of the 58 SOTR study participants, 14 were women and 44 were men; the mean (SD) age was 61.3 (8.4) years. Of the 40 immunocompetent study participants, 16 were women and 24 were men; the mean (SD) age was 69.8 (10.9) years, resulting in a statistically significant difference from the SOTR group. The mean (SD) number of years that SOTRs were immunosuppressed was 14.6 (9.2) years (range, 2-37 years). The SOTR and immunocompetent groups were statistically comparable regarding race and sex, patient care, follow-up time, numbers of skin lesions, and field cancerization and chemopreventive therapies. The SOTR group had a significantly higher annual frequency of visits (mean [SD], 4 [2] vs 3 [2] office visits per patient per year, P = .02) and annual biopsy rates (mean [SD], 6 [4] vs 5 [3] biopsies per patient per year, P = .04). The SOTRs developed SCCs that did not appear to be significantly more aggressive than those found in the immunocompetent control group. These SOTRs also did not develop significantly thicker tumors than the immunocompetent control group (median [IQR] tumor depth, 1.30 [0.90-1.60] mm in 35 SOTRs vs 1.22 [1.10-1.60] mm in 20 immunocompetent patients). Conclusions and Relevance: The increased risk and the potential for aggressive behavior of SCCs in SOTRs may be successfully managed at a level comparable to that in high-risk immunocompetent individuals through close adherence to current dermatologic surveillance recommendations and a marginally lower threshold for biopsy of suspicious lesions for SOTRs.

PMID- 29167863 TI - Association of Parathyroid Hormone Level With Postthyroidectomy Hypocalcemia: A Systematic Review. AB - Importance: There has been an increased interest in measuring parathyroid hormone (PTH) levels as an early predictive marker for the development of hypocalcemia after total thyroidectomy. However, significant variation exists in the timing, type of assay, and thresholds of PTH in the literature. Objective: We performed a systematic review to examine the utility of PTH levels in predicting temporary postthyroidectomy hypocalcemia. Evidence Review: A systematic literature review of studies published prior to May 25, 2016 was performed within PubMed, EMBASE, SCOPUS, and Cochrane databases using the following terms and keywords: "thyroidectomy," "parathyroid hormone," and "hypocalcaemia," "calcium," or "calcitriol." Each candidate full-text publication was reviewed by 2 independent reviewers and selected for data extraction if the study examined the prognostic significance of PTH obtained within 24 hours after thyroidectomy to predict hypocalcaemia. Studies were excluded if calcium supplementation was used routinely or based on a PTH level. Study characteristics, PTH parameters used to predict hypocalcemia, and their respective accuracies were summarized. Findings: The initial search yielded 2417 abstracts. Sixty-nine studies, comprising 9163 patients, were included. Overall, for an absolute PTH threshold, the median accuracy, sensitivity, and specificity were 86%, 85%, and 86%, respectively. For a percentage change over time the median accuracy, sensitivity, and specificity were 89%, 88%, and 90%, respectively. Conclusions and Relevance: The existing literature regarding PTH levels to predict postthyroidectomy hypocalcemia is extremely heterogeneous. A single PTH threshold is not a reliable measure of hypocalcemia. Additional prospective studies controlled for timing of laboratory draws and a priori defined PTH thresholds need to be performed to ascertain the true prognostic significance of PTH in predicting postthyroidectomy hypocalcaemia. PMID- 29167864 TI - Hybrid Cartilage-Modifying Otoplasty Technique and Outcomes. AB - Importance: Otoplasty is performed to correct prominauris, one of the most common head and neck congenital deformities. Advances in combination hybrid approaches enable surgeons to achieve greater precision and accuracy. Objective: To describe a hybrid cartilage-modifying approach and evaluate the procedure's effectiveness and safety. Design, Setting, and Participants: Medical record review including patients undergoing otoplasty by the present technique from January 2006 to December 2016 as performed by the senior author at a tertiary academic referral center. Twenty-three patients underwent 24 total procedures including both bilateral (n = 17) and unilateral (n = 7) procedures. Two procedures were revisions. Interventions: Hybrid cartilage-modifying otoplasty procedure. Main Outcomes and Measures: Preoperative and postoperative measurements were recorded. Paired sample t testing was performed to assess changes between preoperative superior, middle, and inferior helical measurements and corresponding postoperative measurements for all operated ears. Two-tailed, independent sample t testing was performed to compare postoperative differences between right and left ears within separate superior, middle, and inferior measurements in patients undergoing bilateral otoplasty. Results: Twenty-four surgeries were performed on 23 patients. The mean (SD) age at surgery was 16.3 (13.6) years with 13 patients (58%) between the ages of 4 and 10 years. Preoperatively, the mean (SD) superior, middle, and inferior helical rim-to-mastoid distance of the 41 discrete ears measured 16.5 (3.1) mm, 24.1 (3.8) mm, and 19.3 (4.4) mm, respectively. Mean (SD) postoperative measurements were 12.1 (2.4) mm, 14.7 (2.5) mm, and 14.0 (2.8) mm, respectively, for mean (SD) decreases of 4.4 (2.7) mm, 9.4 (3.4) mm, and 5.3 (3.6) mm. For the 17 bilateral procedures, the mean (standard error) postoperative scores between ears measured 0.7 (0.9) mm for the superior, 0.5 (0.9) mm for the middle, and 0.2 (1.0) mm for the inferior. The unaffected ear was measured in 4 of 7 (57%) of patients undergoing unilateral otoplasty, and the mean (SD) postoperative differences between left and right ears were 1.3 (0.8) mm, 3.0 (1.2) mm, and 1.0 (0.7) mm for the superior, middle, and inferior, respectively. Preoperative-to-postoperative differences for all ears (n = 41) were significant (P < .001 for all) for superior, middle, and inferior measurements. There were no significant absolute differences identified for superior (P = .41), middle (P = .58), and inferior (P = .88) measurements regarding left vs right postoperative comparisons for bilateral otoplasties. One patient undergoing bilateral repair required subsequent revision surgery of 1 ear. Two patients developed chronic suture site irritation, and 1 patient developed a hematoma. Conclusions and Relevance: The present technique allows multiple opportunities to adjust the auricular parameters. The results indicate a low revision rate and high degree of symmetry.

PMID- 29167866 TI - Prevalence of Prior Cancer Among Persons Newly Diagnosed With Cancer: An Initial Report From the Surveillance, Epidemiology, and End Results Program. AB - Importance: The US cancer survivor population is rapidly growing. Cancer survivors are frequently excluded from cancer clinical trials and observational research. Objective: To examine prevalence of prior cancer among individuals newly diagnosed with cancer. Design, Setting, and Participants: Linked observations across the population-based Surveillance, Epidemiology, and End Results (SEER) program of cancer registries (1975-2013) for 740 990 persons newly diagnosed with cancer from January 2009 through December 2013. Prevalence of prior cancer was estimated by age (<65 years vs >=65 years) and incident cancer type. Main Outcomes and Measures: Prevalence of prior cancer was derived from SEER sequence numbers, which represent the order of all primary reportable tumors diagnosed in a lifetime. Incident cancers were categorized as: (1) first or only primary; (2) second order or higher primary in the same cancer site; and (3) second order or higher primary in a different cancer site. Results: Of 765 843 incident cancers diagnosed between 2009 and 2013, 141 021 (18.4%) represented a second order or higher primary cancer. Overall, approximately one-fourth (25.2%) of older (>=65 years) and 11% of younger adults newly diagnosed with cancer had a history of prior cancer. Prevalence of prior cancer ranged from 3.5% to 36.9% according to incident cancer type and age, with most prior cancers diagnosed in a different cancer site. Conclusions and Relevance: A substantial proportion of patients diagnosed with incident cancer in the United States have survived a prior cancer. These patients may be excluded from clinical trials and underrepresented in observational research, and little is known about their treatment and survivorship needs. Understanding the nature and impact of prior cancer is critical to improving clinical trial accrual and generalizability, disease outcomes, and patient experience.

PMID- 29167867 TI - Geographic Distribution of Nonphysician Clinicians Who Independently Billed Medicare for Common Dermatologic Services in 2014. AB - Importance: Nurse practitioners (NPs) and physician assistants (PAs) are nonphysician clinicians (NPCs) who can deliver dermatology services. Many of these services are provided independently. Little is known about the types of services provided or where NPCs provide independent care. Objective: To examine characteristics of dermatology care for Medicare enrollees billed independently by NPCs. Design, Setting, and Participants: Retrospective review of the 2014 Medicare Provider Utilization and Payment Data: Physician and Other Supplier Public Use File, which reflects fee-for-service payments to clinicians for services rendered to Medicare beneficiaries. Clinician location was matched with county-level demographic data from the American Community Survey, US Census Bureau. Clinicians identified using National Provider Identifier as NPs or PAs with at least 11 claims for common dermatology-associated Healthcare Common Procedure Coding System procedure codes were included. Main Outcomes and Measures: Total services provided by service type category, density of dermatologists and nondermatologists who perform dermatology-related services, and geographic location by county. Results: Among the cohort of NPCs were 824 NPs (770 [93.5%] female) and 2083 PAs (1602 [76.9%] female) who independently billed Medicare $59 438 802 and $171 645 943, respectively. Dermatologists were affiliated with 2667 (92%) independently billing NPCs. Most payments were for non evaluation and management services including destruction of premalignant lesions, biopsies, excisions of skin cancer, surgical repairs, flaps/grafts, and interpretation of pathologic analysis. Nurse practitioners and PAs billed for a similar distribution of service categories overall. A total of 2062 (70.9%) NPCs practiced in counties with dermatologist density of greater than 4 per 100 000 population. Only 3.0% (86) of independently billing NPCs practiced in counties without a dermatologist. Both dermatologists and NPCs were less likely to be in rural counties than in urban counties. Conclusions and Relevance: Nonphysician clinicians independently billed for a wide variety of complex dermatologic procedures. Most independently billing NPCs practice in counties with higher dermatologist densities, and nearly all these NPCs were affiliated with dermatologists. Further study of NPC training and integration with the dermatology discipline is an important part of addressing the changing US dermatology workforce.

PMID- 29167877 TI - Utility of Imaging-Based Biomarkers for Glutamate-Targeted Drug Development in Psychotic Disorders: A Randomized Clinical Trial. AB - Importance: Despite strong theoretical rationale and preclinical evidence, several glutamate-targeted treatments for schizophrenia have failed in recent pivotal trials, prompting questions as to target validity, compound inadequacy, or lack of target engagement. A key limitation for glutamate-based treatment development is the lack of functional target-engagement biomarkers for translation between preclinical and early-stage clinical studies. We evaluated the utility of 3 potential biomarkers-ketamine-evoked changes in the functional magnetic imaging (fMRI) blood oxygen level-dependent response (pharmacoBOLD), glutamate proton magnetic resonance spectroscopy (1H MRS), and task-based fMRI for detecting ketamine-related alterations in brain glutamate. Objective: To identify measures with sufficient effect size and cross-site reliability to serve as glutamatergic target engagement biomarkers within early-phase clinical studies. Design, Setting, and Participants: This randomized clinical trial was conducted at an academic research institution between May 2014 and October 2015 as part of the National Institute of Mental Health-funded Fast-Fail Trial for Psychotic Spectrum Disorders project. All raters were blinded to study group. Healthy volunteers aged 18 to 55 years of either sex and free of significant medical or psychiatric history were recruited from 3 sites. Data were analyzed between November 2015 and December 2016. Interventions: Volunteers received either sequential ketamine (0.23 mg/kg infusion over 1 minute followed by 0.58 mg/kg/h infusion over 30 minutes and then 0.29 mg/kg/h infusion over 29 minutes) or placebo infusions. Main Outcomes and Measures: Ketamine-induced changes in pharmacoBOLD, 1H MRS, and task-based fMRI measures, along with symptom ratings. Measures were prespecified prior to data collection. Results: Of the 65 volunteers, 41 (63%) were male, and the mean (SD) age was 31.1 (9.6) years; 59 (91%) had at least 1 valid scan. A total of 53 volunteers (82%) completed both ketamine infusions. In pharmacoBOLD, a highly robust increase (Cohen d = 5.4; P < .001) in fMRI response was observed, with a consistent response across sites. A smaller but significant signal (Cohen d = 0.64; P = .04) was also observed in 1H MRS-determined levels of glutamate+glutamine immediately following ketamine infusion. By contrast, no significant differences in task-activated fMRI responses were found between groups. Conclusions and Relevance: These findings demonstrate robust effects of ketamine on pharmacoBOLD across sites, supporting its utility for definitive assessment of functional target engagement. Other measures, while sensitive to ketamine effects, were not sufficiently robust for use as cross-site target engagement measures. Trial Registration: clinicaltrials.gov Identifier: NCT02134951. PMID- 29167879 TI - Racial Differences in Plasma Levels of N-Terminal Pro-B-Type Natriuretic Peptide and Outcomes: The Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study. AB - Importance: Recent studies have suggested that the natriuretic peptide system may be endogenously suppressed in black individuals who are free of prevalent cardiovascular disease. Whether natriuretic peptide levels contribute to racial disparities in clinical outcomes is unknown. Objective: To examine racial differences in N-terminal pro-B-type natriuretic peptide (NTproBNP) levels and their association with all-cause mortality and cause-specific mortality in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. Design, Setting, and Participants: Baseline NTproBNP levels were measured in a randomly selected sample of 4415 REGARDS study participants. Those with prevalent cardiovascular disease and renal dysfunction were excluded. From July 1, 2003, to September 12, 2007, among the remaining 1998 individuals, racial differences in NTproBNP levels were estimated, and the percentage difference in NTproBNP levels by race was meta-analyzed and compared with published results on participants free of prevalent cardiovascular disease from the Dallas Heart Study and Atherosclerosis Risk in Communities study, using random effects modeling. The association of NTproBNP levels, race, all-cause mortality, and cause-specific mortality in the REGARDS study was studied using appropriate modeling techniques. Data analysis was conducted from July 1, 2003, to March 31, 2016. Main Outcomes and Measures: Racial differences in NTproBNP levels and association with all cause mortality and cause-specific mortality. Results: Among the 1998 participants studied (972 women and 1026 men; median age, 63 years [interquartile range, 54-72 years]), median NTproBNP levels in black individuals were significantly lower than those in white individuals (46 pg/mL [interquartile range, 23-91] vs 60 pg/mL [interquartile range, 33-106]; P < .001). With multivariable adjustment, NTproBNP levels were up to 27% lower in black individuals as compared with white individuals (beta, -0.32; 95% CI, -0.40 to 0.24; P < .001) in the REGARDS study. In meta-analysis of the 3 cohorts, NTproBNP levels were 35% lower in black individuals than white individuals. Among the REGARDS study participants, for every 1-SD higher log NTproBNP, there was a 31% increased risk of death in the multivariable-adjusted model (hazard ratio, 1.31; 95% CI, 1.11-1.54). This increase was driven primarily by association of NTproBNP with cardiovascular mortality (hazard ratio, 1.69; 95% CI, 1.19-2.41). No interaction between race and NTproBNP levels was observed with all-cause mortality and cause-specific mortality. Conclusions and Relevance: Plasma NTproBNP levels are significantly lower in black individuals as compared with white individuals in the REGARDS study and in pooled results from the REGARDS study, Dallas Heart Study, and Atherosclerosis Risk in Communities study. Higher NTproBNP levels were associated with higher incidence of all-cause mortality and cardiovascular mortality in healthy black and white individuals, and this association did not differ by race.

PMID- 29167880 TI - Association Between Schizophrenia-Related Polygenic Liability and the Occurrence and Level of Mood-Incongruent Psychotic Symptoms in Bipolar Disorder. AB - Importance: Bipolar disorder (BD) overlaps schizophrenia in its clinical presentation and genetic liability. Alternative approaches to patient stratification beyond current diagnostic categories are needed to understand the underlying disease processes and mechanisms. Objective: To investigate the association between common-variant liability for schizophrenia, indexed by polygenic risk scores (PRSs), and psychotic presentations of BD. Design, Setting, and Participants: This case-control study in the United Kingdom used multinomial logistic regression to estimate differential PRS associations across categories of cases and controls. Participants included in the final analyses were 4436 cases of BD from the Bipolar Disorder Research Network. These cases were compared with the genotypic data for 4976 cases of schizophrenia and 9012 controls from the Type 1 Diabetes Genetics Consortium study and the Generation Scotland study. Data were collected between January 1, 2000, and December 31, 2013. Data analysis was conducted from March 1, 2016, to February 28, 2017. Exposures: Standardized PRSs, calculated using alleles with an association threshold of P < .05 in the second Psychiatric Genomics Consortium genome-wide association study of schizophrenia, were adjusted for the first 10 population principal components and genotyping platforms. Main Outcomes and Measures: Multinomial logit models estimated PRS associations with BD stratified by Research Diagnostic Criteria subtypes of BD, by lifetime occurrence of psychosis, and by lifetime mood incongruent psychotic features. Ordinal logistic regression examined PRS associations across levels of mood incongruence. Ratings were derived from the Schedules for Clinical Assessment in Neuropsychiatry interview and the Bipolar Affective Disorder Dimension Scale. Results: Of the 4436 cases of BD, 2966 (67%) were female patients, and the mean (SD) age at interview was 46 [12] years. Across clinical phenotypes, there was an exposure-response gradient, with the strongest PRS association for schizophrenia (risk ratio [RR] = 1.94; 95% CI, 1.86 2.01), followed by schizoaffective BD (RR = 1.37; 95% CI, 1.22-1.54), bipolar I disorder subtype (RR = 1.30; 95% CI, 1.24-1.36), and bipolar II disorder subtype (RR = 1.04; 95% CI, 0.97-1.11). Within BD cases, there was an effect gradient, indexed by the nature of psychosis. Prominent mood-incongruent psychotic features had the strongest association (RR = 1.46; 95% CI, 1.36-1.57), followed by mood congruent psychosis (RR = 1.24; 95% CI, 1.17-1.33) and BD with no history of psychosis (RR = 1.09; 95% CI, 1.04-1.15). Conclusions and Relevance: For the first time to date, a study shows a polygenic-risk gradient across schizophrenia and BD, indexed by the occurrence and level of mood-incongruent psychotic symptoms.

AB - Importance: The US health care system faces an unsustainable trajectory of high costs and inconsistent outcomes. The fee-for-service payment model has contributed to inefficiency, and new payment methods are a promising approach to improving value. Health reforms are needed to increase patient access, reduce costs, and improve health care quality, and the landmark Medicare Access and CHIP Reauthorization Act presents a roadmap for reform. The product of a collaboration between primary care and cardiology clinicians, this review describes a conceptual approach to delivery and payment reforms that aim to better support primary care-cardiology comanagement of chronic cardiovascular disease (CVD). Observations: Few existing alternative payment models specifically address long term management of CVD. Primary care medical homes and accountable care organizations come closest, but both emphasize primary care, and cardiologists have often not been well engaged. A collaborative care framework should articulate distinct roles and responsibilities for primary care and cardiology in CVD comanagement. Finally, a series of payment models aim to better support clinicians in providing accountable, seamless, and patient-centered cardiac care. Conclusions & Relevance: Clinical leadership is essential during this time of change in the health care system. Patients often struggle to navigate a fragmented and expensive system, whereas clinicians often practice with incomplete information about tests, treatments, and recommendations by their colleagues. The payment models described in this review offer an opportunity to create more satisfying approaches to patient care while improving value. These models have potential to support more effective coordination and to facilitate broader health care system transformation.

AB - Importance: We know of no data on the prognostic value of primary tumor location (PTL) according to BRAF, RAS, and microsatellite instability (MSI) status in patients who have undergone resection for colon cancer (CC) and have been treated with current standard adjuvant chemotherapy. Objective: To determine the prognostic and predictive value of PTL according to BRAF, RAS, and MSI status in patients with stage III CC receiving adjuvant treatment with FOLFOX (folinic acid [leucovorin calcium], fluorouracil, and oxaliplatin) with or without cetuximab. Design, Setting, and Participants: This post hoc analysis included patients with available tumor blocks of resected stage III colon adenocarcinoma who participated in the Pan-European Trials in Alimentary Tract Cancer (PETACC)-8 phase 3 randomized trial. Among the 2559 patients who underwent randomization, 1900 were screened by next-generation sequencing, which showed that 1869 had full information concerning PTL. We categorized primary tumor site as located proximal (right) or distal (left) to the splenic flexure. Main Outcomes and Measures: The associations between PTL (right- vs left-sided) and disease-free survival (DFS), survival after relapse (SAR), and overall survival (OS) were assessed by Cox models and adjusted for clinical and pathological features, treatment, and MSI, BRAF, and RAS status. Results: Among the 1869 patients (1056 [57%] male; mean [SD] age, 59.4 [9.5] years) with full molecular data analyzed, 755 (40%) had a right-sided tumor, 164 (10%) had MSI, 942 (50%) had RAS mutations, and 212 (11%) had BRAF mutations. Right-sided tumor location was not prognostic for DFS in the whole population but was associated with a shorter SAR (hazard ratio [HR], 1.54; 95% CI, 1.23-1.93; P = .001) and OS (HR, 1.25; 95% CI, 1.02-1.54; P = .03). When looking at DFS in the different molecular subgroups, we found similar results for microsatellite-stable tumors and tumors with MSI; a better DFS in right-sided vs left-sided tumors in patients with RAS mutations (HR, 0.80; 95% CI, 0.64-1.00; P = .046); and a worse DFS in right-sided vs left-sided tumors in patients with RAS and BRAF double wild type (HR, 1.39; 95% CI, 1.01-1.92; P = .04). These results were found independently of the treatment received, and no beneficial effect of cetuximab on DFS or OS was observed in left-sided tumors. Conclusions and Relevance: Although right-sided tumor location is associated with poor survival in patients with metastatic CC as previously reported, the association with disease recurrence appears to vary for patients with stage III CC and RAS or BRAF mutations vs those with double wild type.

AB - Importance: The comorbidity of chronic kidney disease and diabetic retinopathy (DR) is well known. However, to our knowledge, no cohort study has demonstrated the effect of chronic kidney disease on the development or progression of DR. Objective: To investigate the association of chronic kidney disease with the development of DR and diabetic macular edema (DME) in type 2 diabetes. Design, Setting, and Participants: This 8-year prospective cohort study that was conducted in 2 medical centers in Taiwan included 2135 patients with type 2 diabetes. Exposures: The baseline and mean follow-up renal profiles including serum creatinine level, estimated glomerular filtration rate (eGFR), and urinary albumin/creatinine ratio (ACR). Main Outcomes and Measures: Diabetic retinopathy and DME were detected with nonmydriatic fundus photography. Cox regression analyses was used to evaluate the hazard ratios (HRs) for the renal profiles of new-onset DR, proliferative DR, and DME. Results: The mean (SD) age of the study participants was 63.4 (11.9) years and 1025 (48%) were women. A higher serum creatinine level (HR of 2.358 for an increase of 1 mg/dL [to convert to micromoles per liter, multiply by 76.25]; 95% CI, 1.901-2.924; P < .001), an estimated glomerular filtration rate of less than 60 mL/min/1.73m2 (40-60: HR, 2.235; 95% CI, 1.351-4.035; P = .002; 30-45: HR, 2.625; 95% CI, 1.436-4.798; P = .002; <30: HR, 5.488; 95% CI, 2.739-10.993; P < .001), and a urinary albumin to creatinine ratio (ACR) of more than 30 mg/g (31-300: HR, 3.202; 95% CI, 2.029 5.053; P < .001; >300: HR, 6.652; 95% CI, 3.922-11.285; P < .001) at baseline were all associated with the development of proliferative DR. A baseline urinary ACR of more than 30 mg/g (31-300: HR, 1.563; 95% CI, 1.078-2.267; P = .02; >300: HR, 2.707; 95% CI, 1.640-4.470; -2.707; P < 0.001) was associated with the development of DME. After adjusting the baseline values, the mean follow-up renal profiles, including a higher serum creatinine level (HR, 2.369 per mg/dL; 95% CI, 1.704-3.293; P < .001), an estimated glomerular filtration rate of less than 30 mL/min/1.73m2 (HR, 4.215; 95% CI, 1.265-14.039; P = .02), and a urinary ACR of more than 30 mg/g (31-300: HR, 2.344; 95% CI, 1.200-4.503; P = .01; >300: HR, 4.193; 95% CI, 1.638-10.735; P = .003) were still correlated with new-onset PDR during the follow-up periods. Conclusions and Relevance: Abnormal renal profiles at baseline, including a high serum creatinine level, low estimated glomerular filtration rate, and high urinary ACR, were associated with the development of PDR in patients with type 2 diabetes. A high baseline urinary ACR was associated with DME. Abnormal mean follow-up renal profiles were still correlated with new onset PDR after adjusting for baseline values. Aggressive treatment for chronic kidney disease may have a role in preventing the deterioration of DR.

Objective: To identify factors associated with failure of adult strabismus-20 (AS-20) HRQOL scores to improve following strabismus surgery. Design, Setting, and Participants: Prospective observational case series at the Mayo Clinic, Rochester, Minnesota, comprising 276 adults, between July 2012 and August 2016.

To assess factors associated with failure of HRQOL to improve (no change or decrease in score), univariate and multiple logistic regression analyses were performed. Each of the 4 AS-20 domains (self-perception, interactions, reading function, and general function) were analyzed separately including only patients able to improve at least by the magnitude of previously defined 95% limits of agreement. Factors assessed were age (at onset and at surgery), sex, number of previous surgeries, presence of visually obtrusive facial anomaly, visual acuity, preoperative and postoperative diplopia questionnaire scores, alignment (as a vector), presence of esotropia, presence of a vertical deviation, CESD-R scores, and type-D personality. Stepwise multiple logistic regression analyses were performed to assess factors associated with failure of AS-20 scores to improve for each domain. Results: Of the 276 participants, the median age was 57 years (range, 18-91 years), 153 were women (55%), and 266 were white (96%). Failure to improve was associated with worse diplopia postoperatively on the self-perception (adjusted risk ratio [RR], 1.01; 95% CI, 1.00-1.02), reading function (adjusted RR, 1.02; 95% CI, 1.01-1.03), and general function domains (adjusted RR, 1.02; 95% CI, 1.01-1.03). In addition, failure to improve on the self-perception domain was associated with type-D personality postoperatively (adjusted RR, 4.26; 95% CI, 1.90-9.57) and failure to improve on the interactions domain was associated with postoperative depressive symptoms (adjusted RR, 1.04; 95% CI, 1.02-1.06) and coexisting visually obtrusive anomaly (adjusted RR, 2.12; 95% CI, 1.04-4.32). Conclusions and Relevance: Postoperative diplopia, depressive symptoms, type-D personality, and visually obtrusive facial anomalies were associated with failure of AS-20 scores to improve (remaining the same or worsening) following strabismus surgery. The association of nonstrabismus factors may have implications for patient treatment and is worthy of continued study.

PMID- 29167901 TI - Association of Neurocognitive Deficits With Radiotherapy or Chemoradiotherapy for Patients With Head and Neck Cancer. AB - Importance: Neurocognitive deficits (NCD) have been observed in noncentral nervous system cancers, yet short- and long-term neurocognitive data on patients treated for head and neck cancer (HNC) are lacking. Objective: To assess objective neurocognitive function before and after definitive radiation therapy for HNC. Design, Setting, and Participants: In a prospective, longitudinal study, neurocognitive function and self-reported symptoms were assessed in 80 patients with histologically proven HNC requiring definitive chemoradiotherapy or radiotherapy and in 40 healthy controls 4 times (baseline, 6, 12, and 24 months after baseline) prior to commencing treatment at Princess Margaret Cancer Centre, Toronto, Canada. Main Outcomes and Measures: Neurocognitive test scores were converted to age-corrected z scores (mean, 0; standard deviation, 1) and reported as mean scores, standardized regression-based scores, and frequencies of impairments in intellectual capacity, concentration, memory, executive function, processing speed, and motor dexterity. Multivariable analysis was used to identify factors associated with NCD 2 years after treatment. Results: Eighty patients and 40 healthy controls enrolled. Analyses revealed significant differences between patient and control mean performance in some domains, with patient deficits increasing over time: intellectual capacity (Cohen d, effect sizes [95% CIs] of -0.46 [-0.64 to 0.30], -0.51 [-0.72 to -0.30], and -0.70 [ 0.92 to -0.49] for time points 6, 12, and 24 months, respectively); concentration/short-term attention span (-0.19 [-0.37 to 0.00], -0.38 [-0.55 to 0.21], -0.54 [-0.71 to -0.37]); verbal memory (-0.16 [-0.33 to 0.02], -0.38 [ 0.64 to -0.12], -0.53 [-0.74 to -0.32]); executive function (-0.14 [-0.27 to 0.00], -0.34 [-0.52 to -0.16], -0.43 [-0.64 to -0.22]), and global cognitive function composite (-0.38 [-0.55 to -0.22], -0.75 [-0.92 to -0.58], -1.06 [-1.26 to -0.86]). There was an increased rate of impaired global neurocognitive functioning among patients (38%) at 24 months compared with controls (0%). Neurocognitive deficits were not associated with baseline cytokines. Conclusions and Relevance: Head and neck cancer survivors have neurocognitive sequelae up to 2 years after definitive chemoradiotherapy or radiation treatment. Patients and health care teams should know about such potential risks. Further research is warranted in search of strategies to avoid, reduce, and compensate for declines. PMID- 29167902 TI - Trends in Use of Ambulatory Surgery Centers for Cataract Surgery in the United States, 2001-2014. AB - Importance: Cataract surgery is commonly performed at ambulatory surgery centers (ASCs) and hospital outpatient departments (HOPDs). These venues differ in many ways, including surgical efficiency, patient throughput, patient safety, and costs per surgery. Objective: To determine trends in use of ASCs and HOPDs for cataract surgery from 2001 to 2014 and factors affecting the site of surgery. Design, Setting, and Participants: This retrospective longitudinal cohort analysis involved individuals 40 years and older who underwent cataract surgery between January 2001 and December 2014 from a nationwide US managed care network. Data were analyzed from February 2016 to February 2017. Main Outcomes and Measures: We identified all enrollees who underwent cataract surgery and determined whether the surgery was performed at an ASC or HOPD. We calculated the proportion of surgeries performed at each site each year from 2001 to 2014. Multivariable logistic regression identified characteristics of enrollees who had cataract surgery at an ASC vs a HOPD. We also assessed geographic variation in the proportion of cataract surgeries performed at ASCs in 306 communities throughout the United States. Results: Of the 369 320 enrollees included in this study, 208 319 (56.4%) were female, and the mean (SD) age was 66.3 (10.4) years. All enrollees underwent cataract surgery (531 325 surgeries) from 2001 to 2014. Of these, 237 046 (64.2%) underwent cataract surgery at an ASC. The proportion of cataract surgeries performed at ASCs increased from 43.6% in 2001 to 73.0% in 2014. Compared with enrollees with incomes less than $40 000, those with incomes greater than $100 000 were 20% more likely to undergo cataract surgery at an ASC (odds ratio, 1.20; 95% CI, 1.12-1.29). Enrollees with better overall health were no more likely to undergo cataract surgery at an ASC (odds ratio, 1.00; 95% CI, 0.99-1.00) than at an HOPD. Enrollees who lived in communities without certificate of need laws were more than twice as likely to have surgery at an ASC (odds ratio, 2.49; 95% CI, 2.35-2.63). The proportion of cataract surgeries performed at ASCs from 2012 to 2014 varied considerably, from 1.6% in La Crosse, Wisconsin, to 98.8% in Pueblo, Colorado. Conclusions and Relevance: We observed a large shift in the site of cataract surgery from HOPDs to ASCs from 2001 to 2014. Future research is needed to assess the effect of this transition in site of surgical care on patient access to surgery, surgical outcomes, patient safety, and societal costs. PMID- 29167903 TI - Access to Ophthalmologists in States Where Optometrists Have Expanded Scope of Practice. AB - Importance: As the United States considers how to best structure its health care services, specialty care availability is receiving increased focus. This study assesses whether patients lack reasonable access to ophthalmologists in states where optometrists have been granted expanded scope of practice. Objective: To determine the estimated travel time (ETT) to the nearest ophthalmologist office for persons residing in states that have expanded scope of practice for optometrists, and to quantify ETT to the nearest ophthalmologist for Medicare beneficiaries who received surgical care from optometrists in those states between 2008 and 2014. Design, Setting, and Participants: This study used data from the 2010 US census, a 2016 American Academy of Ophthalmology member database, and a data set of claims data for a random sample of 20% of beneficiaries enrolled in Medicare nationwide from 2008 to 2014 (n=14 063 725). Combining these sources with geographic information systems analysis, the ETT to the nearest ophthalmologist office was calculated for every resident of Kentucky, Oklahoma, and New Mexico. This study also assessed ETT to the nearest ophthalmologist for Medicare beneficiaries in those states who had received surgery from an optometrist from 2008 to 2014. Data analyses were conducted from July 2016 to July 2017. Main Outcomes and Measures: The proportion of residents of Kentucky, Oklahoma, and New Mexico who live within an ETT of 10, 30, 45, 60, or 90 minutes of the nearest ophthalmologist office. Results: The study included 4 339 367 Kentucky residents, 3 751 351 Oklahoma residents, and 2 059 179 New Mexico residents. Of these, 5 140 547 (50.6%) were female. Racial/ethnic composition included 7 154 847 people (70.5%) who were white, 640 608 (6.3%) who were black, and 1 418 246 (14.0%) who were Hispanic. The mean (SD) age was 37.8 (22.8) years. More than 75% of residents in the 3 states lived within an ETT of 30 minutes to the nearest ophthalmology office, and 94% to 99% of residents lived within an ETT of 60 minutes to the nearest ophthalmology office. Among Medicare beneficiaries who received surgery by optometrists, 58.3%, 51.1%, and 46.9% in Kentucky, Oklahoma, and New Mexico, respectively, lived within an ETT of 30 minutes from the nearest ophthalmologist office. Conclusions and Relevance: In the states where optometrists have expanded scope of practice, most residents lived within an ETT of 30 minutes of the nearest ophthalmologist office, as do half of Medicare beneficiaries who received surgical care from optometrists. These results can help inform policy makers when weighing the pros and cons of scope of practice expansion for optometrists. PMID- 29167904 TI - Prevalence, Characteristics, and Treatment Patterns of Hearing Difficulty in the United States. AB - Importance: Hearing loss is one of the most prevalent chronic conditions in the United States and has been associated with negative physical, social, cognitive, economic, and emotional consequences. Despite the high prevalence of hearing loss, substantial gaps in the utilization of amplification options, including hearing aids and cochlear implants (CI), have been identified. Objective: To investigate the contemporary prevalence, characteristics, and patterns of specialty referral, evaluation, and treatment of hearing difficulty among adults in the United States. Design, Setting, and Participants: A cross-sectional analysis of responses from a nationwide clustered representative sample of adults who participated in the 2014 National Health Interview Survey and responded to the hearing module questions was carried out. Main Outcomes and Measures: Data regarding demographics as well as self-reported hearing status, functional hearing, laterality, onset, and primary cause of the hearing loss were collected. In addition, specific data regarding hearing-related clinician visits, hearing tests, referrals to hearing specialist, and utilization of hearing aids and CIs were analyzed. Results: Among 239.6 million adults, 40.3 million (16.8%) indicated their hearing was less than "excellent/good," ranging from "a little trouble hearing" to "deaf." The mean (SD) age of participants was 47 (0.2) years with 48.2% being men and 51.8% women. Approximately 48.8 million (20.6%) had visited a physician for hearing problems in the preceding 5 years. Of these, 32.6% were referred to an otolaryngologist and 27.3% were referred to an audiologist. Functional hearing was reported as the ability to hear "whispering" or "normal voice" (225.4 million; 95.5%), to "only hear shouting" (8.0 million; 3.4%), and "not appreciating shouting" (2.8 million; 1.1%). Among the last group, 5.3% were recommended to have a CI, of which 22.1% had received one. Of the adults who indicated their hearing from "a little trouble hearing" to being "deaf," 12.9 million (32.2%) had never seen a clinician for hearing problems and 11.1 million (28.0%) had never had their hearing tested. Conclusions and Relevance: There are considerable gaps between self-reported hearing loss and patients receiving medical evaluation and recommended treatments for hearing loss. Improved awareness regarding referrals to otolaryngologists and audiologists as well as auditory rehabilitative options among clinicians may improve hearing loss care. PMID- 29167905 TI - Clinics in diagnostic imaging (181). Cervical spine perineural cysts. AB - A 47-year-old woman who underwent resection of known spinal meningioma at the T1 level returned for postoperative magnetic resonance imaging of the cervical spine. Incidentally, thin-walled structures with signal intensities that are similar to those of cerebrospinal fluid were found to be present in the left neural exit canal at the C7-T1 level and bilateral neural exit canals at the C6-7 level. Imaging findings were in keeping with perineural cysts. Cervical spine perineural cysts are likely underreported, as most of them are asymptomatic. The imaging features and differential diagnoses of perineural cysts are discussed in this article. PMID- 29167906 TI - Ceftriaxone-induced pseudolithiasis: not just a theoretical risk. PMID- 29167907 TI - Definitive tests for dengue fever: when and which should I use? AB - Dengue is a mosquito-borne viral disease that has established itself globally in both endemic and epidemic transmission cycles. While diagnostic decision-making for dengue is often guided by clinical judgement, definitive laboratory tests, including rapid point-of-care tests, have many advantages in the primary care setting. These include providing epidemiological data and diagnostic clarity for atypical cases, as well as contributing to patient education and compliance. This article discussed the types of diagnostic methods for dengue, when to use them and the appropriateness of each test. Viral detection diagnostic methods such as NS1 antigen assays are generally used within the first week of illness onset, whereas dengue serology testing is most appropriate after that time frame. Locally available rapid point-of-care tests, which include both assays in one convenient test kit, can enhance dengue diagnosis in an endemic setting. PMID- 29167908 TI - Pilot single-centre cross-sectional study to determine emergency physicians' knowledge and management of sports concussion: an experience from Singapore. AB - INTRODUCTION: Sports concussion remains challenging to manage despite changes to policy and practice since the 2012 International Consensus Conference on Concussion in Sport. Emergency physicians (EPs) are usually the first line of medical care for athletes in amateur and youth collision sports. This single centre cross-sectional study aimed to establish EPs' understanding and management of concussion in Singapore. METHODS: An anonymised, 17-item online questionnaire was sent to EPs requesting for information on their clinical experience, training, exposure to concussion cases in the emergency department (ED) and assessed knowledge of the condition. RESULTS: Out of 65 EPs, 52 (80%) responded, 25 (48.1%) of whom were medical officers. Over 90% had not received formal training in concussion management, and 73.1% regularly assessed concussion. 40 (76.9%) EPs recognised that loss of consciousness was not essential for diagnosis and only 24 (46.2%) knew the most common symptom. 26 (50.0%) incorrectly reported that they would perform brain imaging. Among those who indicated onward referral, 29 (55.8%) would refer concussed patients to neurosurgery. There were no significant differences between clinical grade or training in concussion and positive responses for definition, imaging modality or most common symptom of concussion. CONCLUSION: Concussion is a common presentation to EDs in Singapore. However, understanding of the condition, its clinical diagnosis, investigation and onward management is limited. Although EPs reported training in concussion, it is likely to be insufficient. Commencing relevant education programmes for undergraduate and postgraduate medical students may enable progressive acquisition of knowledge and thereby improve patient management in the future. PMID- 29167909 TI - Outcomes of neoadjuvant chemoradiotherapy followed by total mesorectal excision surgery for locally advanced rectal cancer: a single-institution experience. AB - INTRODUCTION: Neoadjuvant chemoradiotherapy (CRT) followed by total mesorectal excision (TME) surgery for locally advanced rectal cancer has been shown to improve local control and reduce toxicity, as compared to adjuvant CRT. We reported the outcomes of our patients with locally advanced rectal cancer treated at National University Hospital, Singapore. METHODS: From April 2002 to December 2014, 117 patients with T3/4, N0/+, M0 rectal cancer received neoadjuvant CRT followed by TME surgery. The treatment regimen comprised a total radiotherapy dose of 50.4 Gy in 28 daily fractions delivered concurrently with 5-fluorouracil or capecitabine chemotherapy over 5.5 weeks. All patients were planned for TME surgery. Local control, disease-free survival, overall survival and treatment toxicities were analysed. RESULTS: Median follow-up was 34 (range 2-122) months. 11.5% (13/113) of patients achieved a pathological complete response (pCR) and 72.6% (85/117) had either tumour or nodal downstaging following neoadjuvant CRT. 5.2% (5/96) of patients had Grade 3 acute toxicities (dermatitis and diarrhoea) and 3.1% (3/96) had Grade 3 late toxicities (fistula and stricture). There was no Grade 4 toxicity noted. The five-year local recurrence, disease-free survival and overall survival rates were 4.5%, 65.7% and 80.6%, respectively. Multivariate analysis showed that nodal positivity was a predictor of poor disease-free survival and poor overall survival. Tumour downstaging and pCR did not improve outcomes. CONCLUSION: Our outcomes were comparable to internationally published data, and this treatment regimen remains the standard of care for locally advanced rectal cancer in our local population. PMID- 29167910 TI - Easy-to-learn cardiopulmonary resuscitation training programme: a randomised controlled trial on laypeople's resuscitation performance. AB - INTRODUCTION: Simplifying the learning of cardiopulmonary resuscitation (CPR) is advocated to improve skill acquisition and retention. A simplified CPR training programme focusing on continuous chest compression, with a simple landmark tracing technique, was introduced to laypeople. The study aimed to examine the effectiveness of the simplified CPR training in improving lay rescuers' CPR performance as compared to standard CPR. METHODS: A total of 85 laypeople (aged 21-60 years) were recruited and randomly assigned to undertake either a two-hour simplified or standard CPR training session. They were tested two months after the training on a simulated cardiac arrest scenario. Participants' performance on the sequence of CPR steps was observed and evaluated using a validated CPR algorithm checklist. The quality of chest compression and ventilation was assessed from the recording manikins. RESULTS: The simplified CPR group performed significantly better on the CPR algorithm when compared to the standard CPR group (p < 0.01). No significant difference was found between the groups in time taken to initiate CPR. However, a significantly higher number of compressions and proportion of adequate compressions was demonstrated by the simplified group than the standard group (p < 0.01). Hands-off time was significantly shorter in the simplified CPR group than in the standard CPR group (p < 0.001). CONCLUSION: Simplifying the learning of CPR by focusing on continuous chest compressions, with simple hand placement for chest compression, could lead to better acquisition and retention of CPR algorithms, and better quality of chest compressions than standard CPR.

PMID- 29167913 TI - Synergistic enhancing-memory effect of donepezil and S 47445, an AMPA positive allosteric modulator, in middle-aged and aged mice. AB - Positive allosteric modulators of AMPA receptors (AMPA-PAMs) are described to facilitate cognitive processes in different memory-based models. Among them, S 47445 is a novel potent and selective AMPA-PAM. In order to assess its efficacy after repeated administration, S 47445 effect was evaluated in two aging-induced memory dysfunction tasks in old mice, one short-term working memory model evaluated in a radial maze task and one assessing contextual memory performance. S 47445 was shown to improve cognition in both models sensitive to aging. In fact, administration of S 47445 at 0.3 mg/kg (s.c.) reversed the age-induced deficits of the working memory model whatever the retention interval. Moreover, in the contextual task, S 47445 also reversed the age-induced deficit at all tested doses (from 0.03 to 0.3 mg/kg, p.o.). Since donepezil, an acetylcholinesterase inhibitor, induces only moderate symptomatic effects on memory in Alzheimer's disease patients, an alternative strategy for treatment of cognitive symptoms could be to act simultaneously on both glutamatergic AMPA receptors and cholinergic pathways by combining pharmacological treatments. The present study further examined such effects by assessing combinations of S 47445 and donepezil given orally during 9 days in aged C57/Bl6J mice using contextual memory task (CSD) and the working memory model of serial alternation task (AT). Interestingly, a significant synergistic memory-enhancing effect was observed with the combination of donepezil at 0.1 mg/kg with S 47445 at 0.1 mg/kg p.o. in the CSD or with S 47445 at 0.1 and 0.3 mg/kg in AT in comparison to compounds given alone and without any pharmacokinetic interaction.

AB - PURPOSE: The objective of this study was to evaluate the safety, pharmacokinetics, and pharmacodynamics of S-(-)-pantoprazole (PPZ) sodium injections following single and multiple intravenous doses in healthy Chinese subjects. METHODS: The dosage groups were set as followed: 20 mg of single and multiple intravenous administration of S-(-)-PPZ, 40 mg of single and multiple intravenous administration of S-(-)-PPZ or pantoprazole, and 80 mg of single dosage group of S-(-)-PPZ. Subjects were sampled for pharmacokinetic analysis and were monitored for 24-h intragastric pH prior to and 48-h intragastric pH after administration for the pharmacodynamic study. The pharmacokinetic and pharmacodynamic parameters were compared between S-(-)-PPZ and PPZ. Safety was evaluated on the basis of adverse events, vital signs, laboratory tests, and physical examination. RESULTS: All adverse events were mild and of limited duration. Maximum plasma concentration and area under the concentration-time curve for S-(-)-PPZ were dose proportional over the range of 20-80 mg following a single intravenous administration. Elimination rate constant and half-life observed statistical difference from a single dose to multiple doses in 40 mg of S-(-)-PPZ groups. After administration of a single dose, the mean 24-h intragastric pH value was observed higher in 80-mg group than in 40- and 20-mg groups. Slightly increase of intragastric pH was found after a single dose of 40 mg S-(-)-PPZ than 40 mg PPZ; however, the differences were not statistically significant. CONCLUSIONS: Twice daily of 40 mg S-(-)-PPZ sodium injections is effective in achieving satisfying acid inhibition. Compared with plasma R-(+)-PPZ levels, most subjects presented more potent and prolonged suppression of gastric acid of S-(-)-PPZ, while a few subjects showed faster metabolic rate of S-(-)-PPZ in vivo. PMID- 29167918 TI - Risk factors for QTc interval prolongation. AB - PURPOSE: Prolongation of the QTc interval may result in Torsade de Pointes, a ventricular arrhythmia. Numerous risk factors for QTc interval prolongation have been described, including the use of certain drugs. In clinical practice, there is much debate about the management of the risks involved. In this study, we quantified the effect of these risk factors on the length of the QTc interval. METHODS: We analyzed all ECGs that were taken during routine practice between January 2013 and October 2016 in the Spaarne Gasthuis, a general teaching hospital in the Netherlands. We collected laboratory values in the week before the ECG recording and the drugs prescribed. For the identification of risk factors, we used multilevel linear regression analysis to correct for multiple ECG recordings per patient. RESULTS: We included 133,359 ECGs in our study, taken in 40,037 patients. Patients using one QT-prolonging drug had a 11.08 ms (95% CI 10.63-11.52; p < 0.001) longer QTc interval. Patients using two QT-prolonging drugs had a 3.04 ms (95% CI 2.06-4.02; p < 0.001) increase in the QTc interval compared to patients using one QT-prolonging drug. Women had a longer QTc interval compared to men (16.30 ms 95% CI 14.59-18.01; p < 0.001). The QTc interval increased with increasing age, but the difference between men and women diminished. Other independent risk factors that significantly prolonged the QTc interval with at least 10 ms were hypokalemia, hypocalcemia, and the use of loop diuretics. CONCLUSION: We identified and quantified various risk factors for QTc interval prolongation. PMID- 29167920 TI - ATPase activity regulation by leader peptide processing of ABC transporter maturation and secretion protein, NukT, for lantibiotic nukacin ISK-1. AB - Lantibiotic nukacin ISK-1 is produced by Staphylococcus warneri ISK-1. The dual functional transporter NukT, an ABC transporter maturation and secretion protein, contributes to cleavage of the leader peptide from the prepeptide (modified NukA) and the final transport of nukacin ISK-1. NukT consists of an N-terminal peptidase domain (PEP), a C-terminal nucleotide-binding domain (NBD), and a transmembrane domain (TMD). In this study, NukT and its peptidase-inactive mutant were expressed, purified, and reconstituted into liposomes for analysis of their peptidase and ATPase activities. The ATPase activity of the NBD region was shown to be required for the peptidase activity of the PEP region. Furthermore, we demonstrated for the first time that leader peptide cleavage by the PEP region significantly enhanced the ATPase activity of the NBD region. Taken together, the presented results offer new insights into the processing mechanism of lantibiotic transporters and the necessity of interdomain cooperation.

PMID- 29167919 TI - Propionibacterium spp.-source of propionic acid, vitamin B12, and other metabolites important for the industry. AB - Bacteria from the Propionibacterium genus consists of two principal groups: cutaneous and classical. Cutaneous Propionibacterium are considered primary pathogens to humans, whereas classical Propionibacterium are widely used in the food and pharmaceutical industries. Bacteria from the Propionibacterium genus are capable of synthesizing numerous valuable compounds with a wide industrial usage. Biomass of the bacteria from the Propionibacterium genus constitutes sources of vitamins from the B group, including B12, trehalose, and numerous bacteriocins. These bacteria are also capable of synthesizing organic acids such as propionic acid and acetic acid. Because of GRAS status and their health-promoting characteristics, bacteria from the Propionibacterium genus and their metabolites (propionic acid, vitamin B12, and trehalose) are commonly used in the cosmetic, pharmaceutical, food, and other industries. They are also used as additives in fodders for livestock. In this review, we present the major species of Propionibacterium and their properties and provide an overview of their functions and applications. This review also presents current literature concerned with the possibilities of using Propionibacterium spp. to obtain valuable metabolites. It also presents the biosynthetic pathways as well as the impact of the genetic and environmental factors on the efficiency of their production. PMID- 29167923 TI - Preoperative prediction of microvascular invasion of hepatocellular carcinoma using 18F-FDG PET/CT: a multicenter retrospective cohort study. AB - PURPOSE: The aim of this study was to assess the potential of tumor 18F fluorodeoxyglucose (FDG) avidity as a preoperative imaging biomarker for the prediction of microvascular invasion (MVI) of hepatocellular carcinoma (HCC). METHODS: One hundred and fifty-eight patients diagnosed with Barcelona Clinic Liver Cancer stages 0 or A HCC (median age, 57 years; interquartile range, 50-64 years) who underwent 18F-FDG positron emission tomography with computed tomography (PET/CT) before curative surgery at seven university hospitals were included. Tumor FDG avidity was measured by tumor-to-normal liver standardized uptake value ratio (TLR) of the primary tumor on FDG PET/CT imaging. Logistic regression analysis was performed to identify significant parameters associated with MVI. The predictive performance of TLR and other clinical variables was assessed using receiver operating characteristic (ROC) curve analysis. RESULTS: MVI was present in 76 of 158 patients with HCCs (48.1%). Multivariable logistic regression analysis revealed that TLR, serum alpha-fetoprotein (AFP) level, and tumor size were significantly associated with the presence of MVI (P < 0.001). Multinodularity was not significantly associated with MVI (P = 0.563). The area under the ROC curve (AUC) for predicting the presence of MVI was best with TLR (AUC = 0.704), followed by tumor size (AUC = 0.685) and AFP (AUC = 0.670). We were able to build an improved prediction model combining TLR, tumor size, and AFP by using multivariable logistic regression modeling (AUC = 0.756). CONCLUSIONS: Tumor FDG avidity measured by TLR on FDG PET/CT is a preoperative imaging biomarker for the prediction of MVI in patients with HCC.

AB - PURPOSE: CPX-351 is a novel liposomal formulation of cytarabine and daunorubicin which has recently been FDA approved for treatment of acute myeloid leukemia (AML). The current study investigated the pharmacokinetics (PK) of this liposomal formulation. METHODS: CPX-351 PK data (cytarabine, daunorubicin, and metabolites) from a phase I study of relapsed and refractory AML were used for the analysis. Therapy was given days 1, 3, and 5 of induction (3-134 units/m2). We developed a population PK model to characterize CPX-351 disposition. RESULTS: 39 patients (3589 samples) were evaluated. Liposomal cytarabine and daunorubicin were modeled separately with their respective metabolites. A one-compartment model fit the parent compounds well; the metabolites required two-compartment models. Weight was an independent predictor of liposomal volumes; mild renal and liver dysfunction were not predictors of clearance or volume (maximum creatinine 1.6 mg/dL and total bilirubin 1.8 mg/dL). Liposomal clearances of the two drugs were highly correlated and 1000-fold smaller than published non-encapsulated values supporting prolonged encapsulation in the liposome. CONCLUSIONS: The PK model demonstrates prolonged exposure to cytarabine and daunorubicin without increases in non-hematologic toxicity that indicates retention of the drugs within the liposome. The unique pharmacology of this formulation may allow for simplified regimens and improved outcomes. PMID- 29167925 TI - Why do children and adolescents bully their peers? A critical review of key theoretical frameworks. AB - Bullying is a significant public health problem for children and adolescents worldwide. Evidence suggests that both being bullied (bullying victimisation) and bullying others (bullying perpetration) are associated with concurrent and future mental health problems. The onset and course of bullying perpetration are influenced by individual as well as systemic factors. Identifying effective solutions to address bullying requires a fundamental understanding of why it occurs. Drawing from multi-disciplinary domains, this review provides a summary and synthesis of the key theoretical frameworks applied to understanding and intervening on the issue of bullying. A number of explanatory models have been used to elucidate the dynamics of bullying, and broadly these correspond with either system (e.g., social-ecological, family systems, peer-group socialisation) or individual-level (e.g., developmental psychopathology, genetic, resource control, social-cognitive) frameworks. Each theory adds a unique perspective; however, no single framework comprehensively explains why bullying occurs. This review demonstrates that the integration of theoretical perspectives achieves a more nuanced understanding of bullying which is necessary for strengthening evidence-based interventions. Future progress requires researchers to integrate both the systems and individual-level theoretical frameworks to further improve current interventions. More effective intervention across different systems as well as tailoring interventions to the specific needs of the individuals directly involved in bullying will reduce exposure to a key risk factor for mental health problems. PMID- 29167926 TI - Angiopoietin-like protein 8 in early pregnancy improves the prediction of gestational diabetes. AB - AIMS/HYPOTHESIS: Screening high-risk individuals for gestational diabetes mellitus (GDM) in early pregnancy conventionally relies on established maternal risk factors; however, the sensitivity and specificity of these factors are not satisfactory. The present study aimed to determine whether the concentration of angiopoietin-like protein 8 (ANGPTL8), either alone or combined with other risk factors in early pregnancy, could be used to predict subsequent GDM. METHODS: From August 2015 to January 2016, 474 women receiving prenatal care at around 12 16 weeks of gestation were recruited into the study. ANGPTL8 levels were measured at the first prenatal visit. All the participants received a 75 g OGTT during weeks 24-28 of gestation. RESULTS: ANGPTL8 levels in early pregnancy were considerably higher in women who developed GDM than those who maintained normal glucose tolerance (2822 +/- 938 vs 2120 +/- 1118 pg/ml, respectively; p < 0.0001). Multivariable logistic regression revealed that ANGPTL8 levels were significantly associated with risk of GDM independent of conventional risk factors. In addition, women in the highest quartile of ANGPTL8 concentration had an 8.75-fold higher risk of developing GDM compared with women in the lowest quartile (OR8.75, 95%CI 2.43, 31.58). More importantly, incorporating ANGPTL8 into the conventional prediction model significantly increased the AUC for prediction of GDM (0.772vs 0.725; p = 0.019). CONCLUSIONS: Our study suggests that ANGPTL8 levels in early pregnancy are significantly and independently associated with risk of GDM at 24-28 weeks of gestation. Combining ANGPTL8 levels with conventional risk factors could thus improve the prediction of GDM. PMID- 29167927 TI - New diagnostic criteria for gestational diabetes mellitus and their impact on the number of diagnoses and pregnancy outcomes. AB - AIMS/HYPOTHESIS: Detection and management of gestational diabetes mellitus (GDM) are crucial to reduce the risk of pregnancy-related complications for both mother and child. In 2013, the WHO adopted new diagnostic criteria for GDM to improve pregnancy outcomes. However, the evidence supporting these criteria is limited. Consequently, these new criteria have not yet been endorsed in the Netherlands. The aim of this study was to determine the impact of these criteria on the number of GDM diagnoses and pregnancy outcomes. METHODS: Data were available from 10,642 women who underwent a 75 g OGTT because of risk factors or signs suggestive of GDM. Women were treated if diagnosed with GDM according to the WHO 1999 criteria. Data on pregnancy outcomes were obtained from extensive chart reviews from 4,431 women and were compared between women with normal glucose tolerance (NGT) and women classified into the following groups: (1) GDM according to WHO 1999 criteria; (2) GDM according to WHO 2013 criteria; (3) GDM according to WHO 2013 fasting glucose threshold, but not WHO 1999 criteria; and (4) GDM according to WHO 1999 2 h plasma glucose threshold (2HG), but not WHO 2013 criteria. RESULTS: Applying the new WHO 2013 criteria would have increased the number of diagnoses by 45% (32% vs 22%) in this population of women at higher risk for GDM. In comparison with women with NGT, women classified as having GDM based only on the WHO 2013 threshold for fasting glucose, who were not treated for GDM, were more likely to have been obese (46.1% vs 28.1%, p < 0.001) and hypertensive (3.3% vs 1.2%, p < 0.001) before pregnancy, and to have had higher rates of gestational hypertension (7.8% vs 4.9%, p = 0.003), planned Caesarean section (10.3% vs 6.5%, p = 0.001) and induction of labour (34.8% vs 28.0%, p = 0.001). In addition, their neonates were more likely to have had an Apgar score <7 at 5 min (4.4% vs 2.6%, p = 0.015) and to have been admitted to the Neonatology Department (15.0% vs 11.1%, p = 0.004). The number of large for gestational age (LGA) neonates was not significantly different between the two groups. Women potentially missed owing to the higher 2HG threshold set by WHO 2013 had similar pregnancy outcomes to women with NGT. These women were all treated for GDM with diet and 20.5% received additional insulin. CONCLUSIONS/INTERPRETATION: Applying the WHO 2013 criteria will have a major impact on the number of GDM diagnoses. Using the fasting glucose threshold set by WHO 2013 identifies a group of women with an increased risk of adverse outcomes compared with women with NGT. We therefore support the use of a lower fasting glucose threshold in the Dutch national guideline for GDM diagnosis. However, adopting the WHO 2013 criteria with a higher 2HG threshold would exclude women in whom treatment for GDM seems to be effective. PMID- 29167928 TI - Pulmonary contusions after blunt chest trauma: clinical significance and evaluation of patient management. AB - INTRODUCTION: A pulmonary contusion is an entity defined as alveolar haemorrhage and pulmonary parenchymal destruction after blunt chest trauma. According to the literature, most pulmonary contusions can only be seen on a chest CT. The aim of this study was to evaluate the patients with pulmonary contusions, as well as their management, considering diagnostic and therapeutic options related to their outcomes, since we assumed, based on everyday clinical practice, that an 'overdiagnosing' and 'overtreatment' attitude towards this injury could be present. PATIENTS AND METHODS: The research was a retrospective study including 5042 patients admitted to the Department of Traumatology in the Clinical Hospital Centre Osijek, during a 3-year period. The medical data of the patients who suffered pulmonary contusion were evaluated considering significant characteristics, known risk factors, procedures undergone, and outcomes. RESULTS: During the 3-year period, 2% of all the admitted patients were diagnosed with a pulmonary contusion. In 54% of the cases, the patient suffered polytraumatic injuries. The pulmonary contusion was an isolated injury in 7% of the patients. In 31% of the cases, there was no liquidothorax or pneumothorax (isolated pulmonary contusion). In 89% of the patients the pulmonary contusion was diagnosed using a CT scan. In 68% of the patients there were no interventions regarding the thorax; thoracocentesis was performed in 25% of the cases, and pleural punction in 14% of the cases. 25% of the patients developed respiratory insufficiency and 16% required mechanical ventilation. Regarding isolated pulmonary contusions, respiratory insufficiency was present in 8% of the cases. CONCLUSIONS: We suggest that a pulmonary contusion seen on CT only has limited clinical significance and that the use of CT scans in diagnosing and follow-up of these patients should be re-evaluated. Further prospective and randomised studies should be conducted and the patients should be clinically evaluated, with the administration of supportive and antibiotic therapy, maintaining the fluid balance, the administration of diuretics, supportive oxygen therapy, pulmonary toilet, and physical therapy. PMID- 29167929 TI - Prediction of metabolism-induced hepatotoxicity on three-dimensional hepatic cell culture and enzyme microarrays. AB - Human liver contains various oxidative and conjugative enzymes that can convert nontoxic parent compounds to toxic metabolites or, conversely, toxic parent compounds to nontoxic metabolites. Unlike primary hepatocytes, which contain myriad drug-metabolizing enzymes (DMEs), but are difficult to culture and maintain physiological levels of DMEs, immortalized hepatic cell lines used in predictive toxicity assays are easy to culture, but lack the ability to metabolize compounds. To address this limitation and predict metabolism-induced hepatotoxicity in high-throughput, we developed an advanced miniaturized three dimensional (3D) cell culture array (DataChip 2.0) and an advanced metabolizing enzyme microarray (MetaChip 2.0). The DataChip is a functionalized micropillar chip that supports the Hep3B human hepatoma cell line in a 3D microarray format. The MetaChip is a microwell chip containing immobilized DMEs found in the human liver. As a proof of concept for generating compound metabolites in situ on the chip and rapidly assessing their toxicity, 22 model compounds were dispensed into the MetaChip and sandwiched with the DataChip. The IC50 values obtained from the chip platform were correlated with rat LD50 values, human C max values, and drug induced liver injury categories to predict adverse drug reactions in vivo. As a result, the platform had 100% sensitivity, 86% specificity, and 93% overall predictivity at optimum cutoffs of IC50 and C max values. Therefore, the DataChip/MetaChip platform could be used as a high-throughput, early stage, microscale alternative to conventional in vitro multi-well plate platforms and provide a rapid and inexpensive assessment of metabolism-induced toxicity at early phases of drug development. PMID- 29167930 TI - Planarian cholinesterase: molecular and functional characterization of an evolutionarily ancient enzyme to study organophosphorus pesticide toxicity. AB - The asexual freshwater planarian Dugesia japonica has emerged as a medium throughput alternative animal model for neurotoxicology. We have previously shown that D. japonica are sensitive to organophosphorus pesticides (OPs) and characterized the in vitro inhibition profile of planarian cholinesterase (DjChE) activity using irreversible and reversible inhibitors. We found that DjChE has intermediate features of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Here, we identify two candidate genes (Djche1 and Djche2) responsible for DjChE activity. Sequence alignment and structural homology modeling with representative vertebrate AChE and BChE sequences confirmed our structural predictions, and show that both DjChE enzymes have intermediate sized catalytic gorges and disrupted peripheral binding sites. Djche1 and Djche2 were both expressed in the planarian nervous system, as anticipated from previous activity staining, but with distinct expression profiles. To dissect how DjChE inhibition affects planarian behavior, we acutely inhibited DjChE activity by exposing animals to either an OP (diazinon) or carbamate (physostigmine) at 1 uM for 4 days. Both inhibitors delayed the reaction of planarians to heat stress. Simultaneous knockdown of both Djche genes by RNAi similarly resulted in a delayed heat stress response. Furthermore, chemical inhibition of DjChE activity increased the worms' ability to adhere to a substrate. However, increased substrate adhesion was not observed in Djche1/Djche2 (RNAi) animals or in inhibitor-treated day 11 regenerates, suggesting this phenotype may be modulated by other mechanisms besides ChE inhibition. Together, our study characterizes DjChE expression and function, providing the basis for future studies in this system to dissect alternative mechanisms of OP toxicity.

PMID- 29167932 TI - Identification of phase-II metabolites of flavonoids by liquid chromatography-ion mobility spectrometry-mass spectrometry. AB - Flavonoids are a class of natural compounds with a broad range of potentially beneficial health properties. They are subjected to an extensive intestinal phase II metabolism, i.e., conjugation to glucuronic acid, sulfate, and methyl groups. Flavonoids and their metabolites can interact with drug transporters and thus interfere with drug absorption, causing food-drug interactions. The site of metabolism plays a key role in the activity, but the identification of the various metabolites remains a challenge. Here, we developed an analytical method to identify the phase-II metabolites of structurally similar flavonoids. We used liquid chromatography-ion-mobility spectrometry-mass spectrometry (LC-IMS-MS) analysis to identify phase-II metabolites of flavonols, flavones, and catechins produced by HT29 cells. We showed that IMS could bring valuable structural information on the different positional isomers of the flavonols and flavones. The position of the glucuronide moiety had a strong influence on the collision cross section (CCS) of the metabolites, with only minor contribution of hydroxyl and methyl moieties. For the catechins, fragmentation data obtained from MS/MS analysis appeared more useful than IMS to determine the structure of the metabolites, mostly due to the high number of metabolites formed. Nevertheless, CCS information as a molecular fingerprint proved to be useful to identify peaks from complex mixtures. LC-IMS-MS thus appears as a valuable tool for the identification of phase-II metabolites of flavonoids.

AB - AvidinOX, the oxidized derivative of Avidin, is a chemically modified glycoprotein, being currently under clinical investigation for targeted delivery of radioactive biotin to inoperable tumors. AvidinOX is produced by 4 hydroxyazobenzene-2-carboxylic acid (HABA)-assisted sodium periodate oxidation of Avidin. The peculiar property of the periodate-generated glycol-split carbohydrate moieties to form Schiff's bases with amino groups of the tissue proteins allows to achieve a tissue half-life of 2 weeks compared to 2 h of native Avidin. Carbohydrate oxidation, along with possible minor amino acid modifications, introduces additional microheterogeneity in the glycoprotein structure, making its characterization even more demanding than for native glycoproteins. Aiming at the elucidation of the effects of oxidation conditions on the AvidinOX protein backbone and sugars, this microheterogeneous glycoprotein derivative was characterized for the first time using a combination of different analytical methods, including colorimetric methods, mass spectrometry, hollow fiber flow field-flow fractionation with UV and multi-angle laser scattering detection (HF5-UV-MALS), and NMR. The proposed integrated approach reveals structural features of AvidinOX relevant for its biological activity, e.g., oxidized sites within both carbohydrate moieties and protein backbone and conformational stability, and will be considered as an analytical tool for AvidinOX industrial preparations. It is worth noting that this study enriches also the structural data of native Avidin published up-to-date (e.g., glycan structure and distribution, peptide fingerprint, etc.).

AB - In this work, asymmetrical flow field-flow fractionation (AF4) coupled with UV/Vis, multi-angle light scattering (MALS), and differential refractive index (dRI) detectors (AF4-UV-MALS-dRI) was employed for analysis of glutamate decarboxylase (LbGadB) from Lactobacillus brevis (L. brevis). AF4 provided molecular weight (MW) (or size)-based separation of dimer, hexamer, and aggregates of LbGadB. The effect of pH on oligomerization of LbGadB was investigated, and then AF4 results were compared to those from molecular modeling. The MWs measured by AF4-UV-MALS-dRI for dimeric and hexameric forms of LbGadB were 110 and 350 kDa, respectively, which are in good agreements with those theoretically calculated (110 and 330 kDa). The molecular sizes determined by AF4-UV-MALS-dRI were also in good agreement with those obtained from molecular modeling (6 and 10 nm, respectively, for dimeric and hexameric from AF4-UV-MALS dRI and 6.4 * 7.6 and 7.6 * 13.1 nm from molecular modeling). The effects of temperature, salt type, and salt concentration on oligomerization of LbGadB were also investigated using dynamic light scattering (DLS). It was found that the hexameric form of LbGadB was most stable at pH 6 and in presence of NaCl or KCl. The results indicate that AF4, in combination of various online detectors mentioned above, provides an effective tool for monitoring of oligomerization of LbGadB under different conditions, such as temperature, pH, type of salts, and salt concentrations. PMID- 29167935 TI - Luminol, horseradish peroxidase, and glucose oxidase ternary functionalized graphene oxide for ultrasensitive glucose sensing. AB - Luminol, horseradish peroxidase (HRP), and glucose oxidase (GOx) ternary functionalized graphene oxide (HRP/GOx-luminol-GO) with excellent chemiluminescence (CL) activity and specific enzymatic property was prepared via a simple and general strategy for the first time. In this approach, luminol functionalized GO (luminol-GO) was prepared by gently stirring GO with luminol. Then HRP and GOx were further co-immobilized onto the surface of luminol-GO by storing HRP and GOx with luminol-GO at 4 degrees C overnight, to form HRP/GOx luminol-GO bionanocomposites. The synthesized HRP/GOx-luminol-GO could react with H2O2 generated from GOx catalyzed glucose oxidization reaction, to produce strong CL emission in the presence of co-immobilized HRP. Thus, we developed an ultrasensitive, homogeneous, reagentless, selective, and simple CL sensing system for glucose detection. The resulting biosensors exhibited ultra-wide linear range from 5.0 nM to 5.0 mM, and an ultra-low detection limit of 1.2 nM, which was more than 3 orders of magnitude lower than previously reported methods. Furthermore, the sensing system was successfully applied for the detection of glucose in human blood samples. PMID- 29167936 TI - Potential of dynamically harmonized Fourier transform ion cyclotron resonance cell for high-throughput metabolomics fingerprinting: control of data quality. AB - Due to the presence of pollutants in the environment and food, the assessment of human exposure is required. This necessitates high-throughput approaches enabling large-scale analysis and, as a consequence, the use of high-performance analytical instruments to obtain highly informative metabolomic profiles. In this study, direct introduction mass spectrometry (DIMS) was performed using a Fourier transform ion cyclotron resonance (FT-ICR) instrument equipped with a dynamically harmonized cell. Data quality was evaluated based on mass resolving power (RP), mass measurement accuracy, and ion intensity drifts from the repeated injections of quality control sample (QC) along the analytical process. The large DIMS data size entails the use of bioinformatic tools for the automatic selection of common ions found in all QC injections and for robustness assessment and correction of eventual technical drifts. RP values greater than 106 and mass measurement accuracy of lower than 1 ppm were obtained using broadband mode resulting in the detection of isotopic fine structure. Hence, a very accurate relative isotopic mass defect (RDeltam) value was calculated. This reduces significantly the number of elemental composition (EC) candidates and greatly improves compound annotation. A very satisfactory estimate of repeatability of both peak intensity and mass measurement was demonstrated. Although, a non negligible ion intensity drift was observed for negative ion mode data, a normalization procedure was easily applied to correct this phenomenon. This study illustrates the performance and robustness of the dynamically harmonized FT-ICR cell to perform large-scale high-throughput metabolomic analyses in routine conditions.

AB - Shikimic acid is a intermediate of aromatic amino acid biosynthesis and the preferred starting material for production of the most commonly prescribed anti influenza drug, Tamiflu. Its six-membered carbocyclic ring is adorned with several chiral centers and various functionalities, making shikimic acid a valuable chiral synthon. When microbially-produced, in addition to shikimic acid, numerous other metabolites are exported out of the cytoplasm and accumulate in the culture medium. This extracellular matrix of metabolites is referred to as the microbosphere. Due to the high sample complexity, in this study, the microbosphere of shikimate-producing Escherichia coli SP1.1/pKD15.071 was analyzed by liquid chromatography and comprehensive two-dimensional liquid chromatography coupled to photodiode array and mass spectrometry detection. GC analysis of the trimethylsilyl derivatives was also carried out in order to support the elucidation of the selected metabolites in the microbosphere. The elucidation of the metabolic fraction of this bacterial strain might be of valid aid for improving, through genetic changes, the concentration and yield of shikimic acid synthesized from glucose.

AB - Multi-isotope calibration (MICal) is a novel approach to calibration for inductively coupled plasma mass spectrometry (ICP-MS). In MICal, only two calibration solutions are required: solution A, composed of 50% v v-1 of sample and 50% v v-1 of a standard solution containing the analytes, and solution B, composed of 50% v v-1 of sample and 50% v v-1 of a blank solution. MICal is based on monitoring the signal intensities of several isotopes of the same analyte in solutions A and B. By plotting the analytical signals from solution A in the x axis, and from solution B in the y-axis, the analyte concentration in the sample is calculated using the slope of that graph and the concentration of the reference standard added to solution A. As both solutions contain the same amount of sample, matrix-matching is easily achieved. In this proof-of-concept study, MICal was applied to the determination of Ba, Cd, Se, Sn, and Zn in seven certified reference materials with different matrices (e.g., plant materials, flours, and water). In most cases, MICal results presented no statistical difference from the certified values at a 95% confidence level. The new strategy was also compared with traditional calibration methods such as external calibration, internal standardization and standard additions, and recoveries were generally better for MICal. This is a simple, accurate, and fast alternative method for matrix-matching calibration in ICP-MS.

AB - The prognostic value of peripheral blasts (PB) is not well-studied in patients with myelodysplastic syndromes (MDS). We evaluated the impact of PB on overall survival (OS) and transformation to acute myeloid leukemia (AML) in a large cohort. The MDS database at the Moffitt Cancer Center was retrospectively reviewed to identify patients with >= 1% PB (PB-MDS) and those without PB (BM MDS). We also assessed the correlation between PB and gene mutations. One thousand seven hundred fifty-eight patients were identified, among whom 13% had PB near the time of diagnosis. PB-MDS patients were more likely to be younger with trilineage cytopenia, complex karyotype, higher-risk disease, transfusion dependence, and therapy-related MDS. The rate of AML transformation was 49 vs. 26% (p < 0.005) and median OS was 16.5 vs. 45.8 months (p < 0.005) in the PB-MDS and BM-MDS groups, respectively. In Cox regression analysis, the presence of PB was an independent prognostic covariate for OS, HR 1.57 (95% CI 1.2-2). Among 51 patients with an available gene panel, the rate of >= 1 gene mutation in the PB MDS group (n = 4) was 100% compared to 81% in the BM-MDS group (n = 47). The presence of PB in MDS is an adverse independent prognostic variable that refines prognostic discrimination. PMID- 29167939 TI - The properdin pathway: an "alternative activation pathway" or a "critical amplification loop" for C3 and C5 activation? AB - This review is not intended to cover in detail all aspects of the discovery and evolution of our understanding of the "alternative pathway" of complement activation, there are many excellent reviews that do this (see Fearon (CRC Crit Rev Immunol 1:1-32, 1979), Pangburn and Muller-Eberhard (Springer Semin Immunopathol 7:163-192, 1984)), but instead to give sufficient background for current concepts to be put in context. The prevailing textbook view, of components having a primary role as an alternative "pathway" for C3 activation, is challenged, with an argument developed for the primary role of the system being that of providing a surface-dependent amplification loop for both C3 and C5 activation. Whatever the mechanism by which the initial C3b molecule is generated, deposition onto a surface has the potential to target that surface for elimination. Elimination or escape from initial targeting is determined by a sophisticated and highly regulated amplification loop for C3 activation. This viewpoint of the system is then briefly developed to provide a context for therapeutic treatment of disease caused, at least in part, by dysregulated amplification of C3 activation, and to highlight some of the challenges that such therapies will face and need to address. PMID- 29167943 TI - Penetrating Crohn disease: does it occur in the absence of stricturing disease? AB - PURPOSE: To establish the relationship between penetrating complications and bowel luminal narrowing/stricturing disease in pediatric Crohn disease (CD). MATERIALS AND METHODS: This retrospective study was IRB-approved and HIPAA compliant with waiver of informed consent. CT and MRI examinations describing intra-abdominal penetrating complications in CD patients <= 18 years old between January 1, 2009 and March 31, 2016 were reviewed to document: type of complication, affected bowel segment, minimum bowel luminal diameter, maximum upstream diameter, location of penetrating complication relative to luminal narrowing, length of narrowed bowel segment, and the presence of active bowel wall inflammation. Data were summarized using descriptive statistics including means, standard deviations, as well as counts and percentages. RESULTS: A total of 52 penetrating complications were identified in 45 patients. Mean patient age was 15.7 +/- 2.2 years (range 11-18 years) with 25/45 (56%) boys. Nearly all penetrating complications (51/52, 98%) were associated with a minimum bowel luminal diameter of <= 2 mm, with no visible lumen in 26/52 (50%). Mean maximum upstream diameter was 2.8 +/- 0.8 cm (range 1.2-5.2 cm), and 17/52 (33%) penetrating complications were associated with > 3 cm upstream diameter. The mean ratio of maximum to minimum luminal diameter was 26.2 +/- 8.8 (range 3.6-52.0). Active intestinal inflammation was associated with 100% (52/52) of penetrating complications. Nearly every penetrating complication (51/52, 98%) involved the terminal or distal ileum. CONCLUSIONS: Penetrating complications in pediatric CD nearly always occur in the setting of considerable luminal narrowing or stricture and active intestinal inflammation.

AB - PURPOSE: The purpose of this study was to investigate the collapse progression in different morphologies of the necrotic-viable interface in osteonecrosis of the femoral head (ONFH). METHODS: A total of 168 patients (202 hips) with Association Research Circulation Osseous (ARCO) stage II ONFH were included. Ending with the collapse of the femoral head, all patients received conservative treatment but without surgical intervention and were followed for three to 91 months. Bilateral hip-joint radiographs and magnetic resonance imaging (MRI) were examined, and the largest layer of necrosis within the coronal section of MRI images was selected together with its anteroposterior radiograph to observe the morphology of the necrotic-viable interface. The morphology was divided into four types: I, type transverse; II, type "V"; III, type zigzag; IV, type closed. The collapse rate and the time to collapse in different morphologies were assessed. RESULTS: A total of 120 hips collapsed in two years or less, 61 were type-I, 51 were type II, and 8 were type-III. Non-collapse occurred in all 17 hips with type-IV ONFH during long-term follow-up. In 202 hips with ARCO stage-II ONFH, the collapse rate in type-I ONFH was significantly higher than that of type-II and type-III ONFH (P < 0.01 for both). The time to collapse was markedly shortened. CONCLUSIONS: The risk of ONFH-induced collapse is influenced by the morphology of the necrotic-viable interface. Effective mechanical support for preventing the collapse of the femoral head is necessary when the morphology of the necrotic viable interface is type transverse.

However, beaver dams and dam like structures also harbor a history of social conflict. Hence, we identified a need to assess the use of beaver-related restoration projects in western rangelands to increase awareness and accountability, and identify gaps in scientific knowledge. We inventoried 97 projects implemented by 32 organizations, most in the last 10 years. We found that beaver-related stream restoration projects undertaken mostly involved the relocation of nuisance beavers. The most common goal was to store water, either with beaver dams or artificial structures. Beavers were often moved without regard to genetics, disease, or potential conflicts with nearby landowners. Few projects included post-implementation monitoring or planned for longer term issues, such as what happens when beavers abandon a site or when beaver dams or structures breach. Human dimensions were rarely considered and water rights and other issues were mostly unresolved or addressed through ad-hoc agreements. We conclude that the practice and implementation of beaver-related restoration has outpaced research on its efficacy and best practices. Further scientific research is necessary, especially research that informs the establishment of clear guidelines for best practices.

Cancer progression is thought to be driven by a small population of tumour cells possessing stem cell properties. Hypoxia-inducible factors (HIFs) are important mediators of hypoxia. Both HIF-1alpha and HIF-2alpha have been reported to be expressed in thyroid cancers. There is growing evidence that the HIF pathway plays a significant role in the maintenance of thyroid cancer stem cells (CSC). METHODOLOGY: We have isolated thyroid CSC from a papillary thyroid cancer-derived cell line (BCPAP) and an anaplastic thyroid cancer-derived cell line (SW1736) as side population (SP) cells (a putative stem cell population) and treated them with cobalt chloride (II) to induce hypoxia. RESULTS AND DISCUSSION: We observed an increase in the SP of cells within the thyroid cancer cell lines following induction of hypoxia. PMID- 29167951 TI - Radioembolization Versus Bland Embolization for Hepatic Metastases from Small Intestinal Neuroendocrine Tumors: Short-Term Results of a Randomized Clinical Trial. AB - BACKGROUND: Radioembolization (RE) with intra-arterial administration of 90Y microspheres is a promising technique for the treatment of liver metastases from small intestinal neuroendocrine tumors (SI-NET) not amenable to surgery or local ablation. However, studies comparing RE to other loco-regional therapies are lacking. The aim of this randomized study was to compare the therapeutic response and safety after RE and bland hepatic arterial embolization (HAE), and to investigate early therapy-induced changes with diffusion-weighted MRI (DWI-MRI). METHODS: Eleven patients were included in a prospective randomized controlled pilot study, six assigned to RE and five to HAE. Response according to RECIST 1.1 using MRI or CT at 3 and 6 months post-treatment was recorded as well as changes in DWI-MRI parameters after 1 month. Data on biochemical tumor response, toxicity, and side effects were also collected. RESULTS: Three months after treatment, all patients in the HAE group showed partial response according to RECIST while none in the RE group did (p = 0.0022). After 6 months, the response rates were 4/5 (80%) and 2/6 (33%) in the HAE and RE groups, respectively (NS). DWI-MRI metrics could not predict RECIST response, but lower pretreatment ADC(120 800) and larger ADC(0-800) increase at 1 month were related to larger decrease in tumor diameter when all tumors were counted. CONCLUSION: HAE resulted in significantly higher RECIST response after 3 months, but no difference compared to RE remained after 6 months. These preliminary findings indicate that HAE remains a safe option for the treatment of liver metastases from SI-NET, and further studies are needed to establish the role of RE and the predictive value of MR-DWI. PMID- 29167952 TI - Growth of Focal Nodular Hyperplasia is Not a Reason for Surgical Intervention, but Patients Should be Referred to a Tertiary Referral Centre. AB - BACKGROUND: When a liver lesion diagnosed as focal nodular hyperplasia (FNH) increases in size, it may cause doubt about the initial diagnosis. In many cases, additional investigations will follow to exclude hepatocellular adenoma or malignancy. This retrospective cohort study addresses the implications of growth of FNH for clinical management. METHODS: We included patients diagnosed with FNH based on >=2 imaging modalities between 2002 and 2015. Characteristics of patients with growing FNH with sequential imaging in a 6-month interval were compared to non-growing FNH. RESULTS: Growth was reported in 19/162 (12%) patients, ranging from 21 to 200%. Resection was performed in 4/19 growing FNHs; histological examination confirmed FNH in all patients. In all 15 conservatively treated patients, additional imaging confirmed FNH diagnosis. No adverse outcomes were reported. No differences were found in characteristics and presentation of patients with growing or non-growing FNH. CONCLUSION: This study confirms that FNH may grow significantly without causing symptoms. A significant increase in size should not have any implications on clinical management if confident diagnosis by imaging has been established by a tertiary benign liver multidisciplinary team. Liver biopsy is only indicated in case of doubt after state-of-the-art imaging. Resection is deemed unnecessary if the diagnosis is confirmed by multiple imaging modalities in a tertiary referral centre. PMID- 29167953 TI - Result of Thoracic Endovascular Aortic Repair for Patients with Esophageal Cancer. AB - BACKGROUND: Bleeding from the thoracic aorta is potentially fatal in patients with advanced esophageal cancer. Thoracic endovascular aortic repair (TEVAR) was recently applied for aortic invasion by esophageal cancer. However, only a few case reports have been published. This study was performed to clarify the effectiveness and safety of TEVAR for patients with advanced esophageal cancer. METHODS: We retrospectively reviewed 18 patients who underwent TEVAR for esophageal cancer. We also performed a literature search and reviewed 21 similar cases. RESULTS: From 2007 to 2016, 10 patients were treated on an emergent basis for aortic hemorrhage (salvage group) and 8 patients underwent urgent prophylactic surgery (prophylactic group). Hemostasis was achieved in all cases. One (10%) patient in the salvage group died of aspiration pneumonia on postoperative day 1, while all patients in the prophylactic group survived for >1 month. The median survival period in the salvage and prophylactic group was 3.25 and 11.10 months, respectively. The longest survivor was still alive 9 years after TEVAR and chemoradiotherapy. No fatal adverse events or negative impacts on subsequent treatment for esophageal cancer occurred. CONCLUSIONS: TEVAR is feasible, safe, and effective in preventing fatal aortic hemorrhage secondary to esophageal cancer invasion, although it is palliative in most cases. Because the outcomes of emergent TEVAR after bleeding tended to be worse in the salvage than in prophylactic group, prophylactic TEVAR may be considered a viable treatment option for patients with aortic invasion by advanced esophageal cancer. PMID- 29167954 TI - No implant migration and good subjective outcome of a novel customized femoral resurfacing metal implant for focal chondral lesions. AB - PURPOSE: Managing focal cartilage injuries in the middle-aged patient poses a challenge. Focal prosthetic inlay resurfacing has been proposed to be a bridge between biologics and conventional joint arthroplasty. Patient selection and accurate implant positioning is crucial to avoid increased contact pressure to the opposite cartilage surface. A customized femoral condyle implant for focal cartilage injuries was designed to precisely fit each patient's individual size and location of damage. The primary objective was to assess implant safety profile, surgical usability of the implant and instruments, and implant migration with radiostereometric analysis (RSA). METHODS: Ten patients 36-56 years with focal chondral defects, ICRS 3-4 of the femoral cartilage and failed earlier conservative or surgical interventions with VAS pain > 40. The patients were followed for 2 years with subjective outcome measures (VAS, EQ5D, KOOS) and RSA. The customized implant and guide instruments were manufactured by computer-aided design/computer-aided manufacturing (CAD/CAM) techniques using MRI data. RESULTS: VAS, EQ5D and KOOS showed improvements that reached significance for VAS (p <= 0.001), Tegner (p = 0.034) and the KOOS subscores ADL (p = 0.0048), sport and recreation (p = 0.034) and quality of life (p = 0.037). VAS and KOOS scores improved gradually at 3, 6 and 12 months. The improvements in EQ5D, KOOS pain and KOOS symptoms did not reach statistical significance. No infections, deep venous thrombosis or other complications occured in the postoperative period. No radiographic signs of damage to the opposing tibial cartilage was noted. The surgical usability of implants and instruments were good. RSA did not show any implant migration. CONCLUSION: This is the first clinical report of a new customized, focal knee resurfacing system. The short-term implant safety and patient-related outcome measures showed good-to-excellent results. LEVEL OF EVIDENCE: Prospective case series, Level 4. PMID- 29167955 TI - Step-wise medial collateral ligament needle puncturing in extension leads to a safe and predictable reduction in medial compartment pressure during TKA. AB - PURPOSE: Medial soft tissue release in a varus deformity knee during total knee arthroplasty is essential for accurate balancing of the reconstruction. This study attempts to quantify the effect of sequential needle puncturing of the medial collateral ligament (MCL) using a pressure sensor insert (Verasense by OrthoSensor) and gap measurement under tension. METHODS: Cruciate-retaining arthroplasties were placed in 14 cadaveric knees. The MCL was elongated by step wise perforation, in five sets of five perforations, with the use of an 18-gauge needle, followed by valgus stress. Following the fifth set of needle perforations, blade perforation was performed on the remaining tense fibers of the MCL. Following each step-wise perforation, corresponding medial compartment pressures and gap measurements under tension were recorded. RESULTS: Sensor measurements correlated closely with step-wise tissue release (R = 0.73, p < 0.0001), and a significant decrease in pressure was found in early needle puncturing (mean 49 N after 5, 83 N after 15, p values < 0.05), although changes diminished at later stages of needle perforation (90 N after 20). Gap measurement demonstrated small gradual changes with early puncturing, but showed significant opening in the later stages of release. There was minimal variation in pressure or gap measurements in flexion versus extension. This finding suggests that MCL needle puncture will not lead to unequal gaps between flexion and extension. There were no cases of MCL over-release after 15 punctures, one case after 20 punctures, and three after blade perforation. CONCLUSION: Needle puncturing of the MCL in extension for up to 15 punctures can be a safe and predictable way to achieve medial opening when balancing a varus knee during TKA as demonstrated in this cadaveric model. Blade perforation should be used with caution to avoid over release. The needle puncture method can be used by surgeons to achieve reliable reductions in medial compartment pressures, to help achieve a balanced TKA, with minimal risk of over-release.

AB - After using various techniques with various results, Bostwick's principles for breast reconstruction were used in mastectomy cases and their early results are presented. The breast reconstructions were performed to 12 cases, of which eight patients had one or two risk factors and four had more. The double-pedicle technique was used in the former and vascular delay preceding double-pedicle technique was used in the latter. No vascular compromises, arterial or venous, were observed on the flaps in the acute phase and no fat necrosis ensued lately. All patients were satisfied with these principles and we did not observe any problems with the flaps. We have concluded that Bostwick's principles offered a reliable and minimal risk basis for breast reconstructive surgeons. PMID- 29167958 TI - Reply to Troilius.

AB - The exact mechanism of cadmium (Cd) immobilization by oyster shell (OS) has not been reported. The effect of OS on Cd immobilization and the exact mechanism should be known before applying remediation technology using OS to Cd contaminated soils. Therefore, the objective of this study was to elucidate the mechanism of Cd immobilization by OS. Three grams of OS (< 0.84 mm) was reacted with 30 mL of 0-3.56 mg Cd L-1 solution at 25 degrees C for 48 h. Cadmium adsorption increased with increasing initial concentration of Cd in solution. The X-ray diffraction patterns clearly demonstrated that precipitation of CdCO3 did not take place in suspensions of OS after reacting with up to 3.56 mol Cd L-1. Interestingly, we found formation of Ca0.67Cd0.33CO3 crystalline in suspension of OS after reacting with maximum initial Cd concentrations. Precipitation and chemisorption might contribute to Cd immobilization together. However, we feel confident that chemisorption is the major mechanism by which Cd immobilization occurs with OS. In conclusion, OS could be an effective bioadsorbent to immobilize Cd through formation of geochemically stable Cd mineral. PMID- 29167965 TI - Impact of Suspended Solids on the Use of LuminoTox to Detect Toxicity of Micropollutants. AB - There is an increasing need for tools to monitor toxicity of contaminants of emerging concern (CECs) in wastewater. The purpose of this work was to assess interferences in the presence of total solids (TS) and total suspended solids (TSS) in the LuminoTox at concentrations typical of those found in municipal secondary effluent (SE) and to evaluate a simple sample enrichment method for increased CEC sensitivity. 4 or 10 ug/L atrazine in different TS concentrations and in corresponding filtrates (TSS removed) exhibited equivalent toxicities. Because the only difference between these two fractions is the TSS, this result demonstrates that, generally, this fraction does not induce toxicity nor interfere with the bioassay. At constant medium-low TS, the LuminoTox was able to detect the presence of 4 ug/L of atrazine but could not distinguish the change in atrazine concentration between 4 and 6 ug/L. No inhibition was observed in the presence of a mix of 14 CECs each at 0.23 ug/L. However, upon sample enrichment by lyophilization (50*), an inhibition of 81 +/- 3% was observed. The enriched SE alone (not spiked with CECs) led to an inhibition of 49 +/- 1%, indicating the detection of the CEC contribution to toxicity after sample preconcentration. The LuminoTox is a promising tool for monitoring SE; however, if the intent is to detect CECs, enrichment method optimization is required. PMID- 29167966 TI - Planning Prostate Artery Embolisation: Is it Essential to Perform a Pre procedural CTA? AB - PURPOSE: A highly variable prostatic artery origin coupled with frequent anastomoses to adjacent organs makes prostate artery embolisation a challenging procedure. Despite CT angiography facilitating procedural planning, it is not performed in all centres. Therefore, we explored the utility of prostatic CT angiography by assessing its capacity to identify the prostatic arteries and highlight troublesome anastomoses. MATERIALS AND METHODS: A retrospective review of patients undergoing prostate artery embolisation for symptoms of benign prostatic obstruction between June 2012 and October 2016 was conducted, with analysis of the pre-procedural CT angiography. CT findings were compared with subsequent intraprocedural angiography to assess the accuracy with which CT angiography predicts the origin of prostatic arteries and identifies anastomoses. RESULTS: In total, 110 patients underwent prostate artery embolisation, with pre procedural CT angiography acquired in all patients, enabling assessment of 220 pelvic sides of hemiprostatic arterial supply. Mean dose length product was 808.4 mGycm. CT angiography successfully identified prostatic arterial supply in 214/220 pelvic sides, an accuracy of 97.3%. Anastomoses of prostatic vessels were suggested by CT angiography in 52 pelvic sides. These were confirmed by angiogram in 49/52 sides (94.2%). CT angiography demonstrated a sensitivity of 59.0% and specificity of 94.2% for anastomoses detection. CONCLUSION: CT angiography prior to embolisation reliably predicts the arterial anatomy and facilitates procedural planning. Therefore, it should be a considered as a pre-procedural investigation for patients undergoing prostate artery embolisation. Sensitivity is low for predicting anastomoses, so careful periprocedural evaluation of the target vessels is still required. PMID- 29167967 TI - Safety and Feasibility of Chemoembolization with Doxorubicin-Loaded Small Calibrated Microspheres in Patients with Hepatocellular Carcinoma: Results of the MIRACLE I Prospective Multicenter Study. AB - PURPOSE: The MIRACLE I pilot study was designed as a preliminary investigation of safety and efficacy of Embozene TANDEM microspheres loaded with doxorubicin for treatment of locally untreatable (i.e., unresectable and not suitable for local thermal ablation) hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Patients with locally untreatable HCC (mono- or bilobar disease, ECOG performance status 0 2, Child-Pugh score < 11) were eligible for this single-arm multicenter study. DEB-TACE was performed with 75 um Embozene TANDEM loaded with 150 mg of doxorubicin. RESULTS: Twenty-five subjects with 41 tumors were treated (mean age 65 years); 16, 52, and 32% had BCLC A, B, and C status, respectively. Child-Pugh status was A for 64%, B for 32%, and C for 4%; 40% had ascites. About 92% had disease localized to one liver lobe. Most (72%) underwent <= 2 DEB-TACE procedures. Average doxorubicin dose was 124.5 +/- 36.1 mg (median 150 mg) per procedure. Two patients had procedure-related SAE (liver necrosis, worsening of liver insufficiency) within 30 days of the first DEB-TACE procedure. Six-month freedom from procedure-related SAE or death was 68% (one hepatic encephalopathy, five deaths). Tumor response or stable disease was achieved in 95% (20/21) of subjects. Freedom from tumor progression or death at 6 months was 76%. The one year survival rate was 56% overall and 73% among patients without ascites at baseline. CONCLUSION: MIRACLE I results suggest that Embozene TANDEM microspheres loaded with doxorubicin can provide good local tumor control in a heterogeneous group of patients with locally untreatable HCC.

AB - OBJECTIVE: To investigate the performance of hybrid angio-CT in preoperative detection and localization for insulinomas. METHODS: Fifty-four postoperative pathology-confirmed patients from April 2015 to March 2017 were retrospectively reviewed; all patients underwent angio-CT with administration of contrast media in SMA, GDA and SA due to negative, inconclusive or controversial findings by several preoperative diagnostic methods including TAUS, CEUS, EUS, ECT, EMRI and DSA. Surgery was used as gold standard for localization of insulinomas; detection sensitivity and localization accuracy of angio-CT were assessed and compared with other preoperative image options. RESULTS: Fifty-six benign insulinomas (mean diameter, 15.8 mm) in 54 patients (18 men and 36 women) were found according to surgical results; the overall detection sensitivity of TAUS, CEUS, EUS, ECT, EMRI and DSA was 21.4, 78.4, 79.2, 70.0, 79.2 and 72.2%, respectively. The overall localization accuracy was 14.3, 58.8, 68.8, 60.0, 75.0 and 44.4%, respectively. A total of 53 tumors were detected by angio-CT, 51 tumors were accurately located, and the overall detection sensitivity and localization accuracy of angio-CT was 94.4 and 90.7%, which was significantly higher than that of all other preoperative diagnostic methods (p < 0.05). No any serious complications occurred during angio-CT. CONCLUSION: Our study indicates the great potential value of angio-CT in the preoperative detection and localization of insulinomas; angio-CT can be used as a preferred invasive diagnostic method. PMID- 29167969 TI - Association of incident hip fracture with the estimated femoral strength by finite element analysis of DXA scans in the Osteoporotic Fractures in Men (MrOS) study. AB - : Finite element model can estimate bone strength better than BMD. This study used such a model to determine its association with hip fracture risk and found that the strength estimate provided limited improvement over the hip BMDs in predicting femoral neck (FN) fracture risk only. INTRODUCTION: Bone fractures occur only when it is loaded beyond its ultimate strength. The goal of this study was to determine the association of femoral strength, as estimated by finite element (FE) analysis of DXA scans, with incident hip fracture as a single condition or with femoral neck (FN) and trochanter (TR) fractures separately in older men. METHODS: This prospective case-cohort study included 91 FN and 64 TR fracture cases and a random sample of 500 men (14 had a hip fracture) from the Osteoporotic Fractures in Men study during a mean +/- SD follow-up of 7.7 +/- 2.2 years. We analysed the baseline DXA scans of the hip using a validated plane stress, linear-elastic FE model of the proximal femur and estimated the femoral strength during a sideways fall. RESULTS: The estimated strength was significantly (P < 0.05) associated with hip fracture independent of the TR and total hip (TH) BMDs but not FN BMD, and combining the strength with BMD did not improve the hip fracture prediction. The strength estimate was associated with FN fractures independent of the FN, TR and TH BMDs; the age-BMI-BMD adjusted hazard ratio (95% CI) per SD decrease of the strength was 1.68 (1.07-2.64), 2.38 (1.57, 3.61) and 2.04 (1.34, 3.11), respectively. This association with FN fracture was as strong as FN BMD (Harrell's C index for the strength 0.81 vs. FN BMD 0.81) and stronger than TR and TH BMDs (0.8 vs. 0.78 and 0.81 vs. 0.79). The strength's association with TR fracture was not independent of hip BMD. CONCLUSIONS: Although the strength estimate provided additional information over the hip BMDs, its improvement in predictive ability over the hip BMDs was confined to FN fracture only and limited. PMID- 29167970 TI - Independent association of bone mineral density and trabecular bone score to vertebral fracture in male subjects with chronic obstructive pulmonary disease. AB - : Osteoporosis is a major comorbidity of chronic obstructive pulmonary disease (COPD), but the mechanism of bone fragility is unknown. We demonstrated that trabecular bone score, a parameter of bone quality, was associated with systemic inflammation and was a significant determinant of vertebral fracture independent of bone mineral density. INTRODUCTION: COPD is a major cause of secondary osteoporosis. However, the mechanism of bone fragility is unclear. We previously reported that vertebral fracture was highly prevalent in male COPD patients. To obtain clues to the mechanism of COPD-associated osteoporosis, we attempted to identify determinants of prevalent vertebral fracture in this study. METHODS: In this cross-sectional study, we recruited 61 COPD males and examined pulmonary function, vertebral fractures, bone mineral density (BMD), trabecular bone score (TBS), bone turnover markers, and inflammatory parameters. Determinants of the bone parameters were examined by multivariable analyses. RESULTS: The prevalence of any and grade 2 or 3 fractures was 75.4 and 19.7%, respectively. Osteoporosis and osteopenia defined by BMD were present in 37.7 and 39.3%, respectively. TBS was significantly lower in higher Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages compared to GOLD 1. Multivariable logistic regression analysis revealed that both TBS and BMD were independent determinants of grade 2 or 3 vertebral fractures (OR = 0.271, 95%CI 0.083-0.888, p = 0.031; OR = 0.242, 95%CI 0.075-0.775, p = 0.017) after adjustment for age. Correlates of TBS included age, BMD, high-sensitivity C-reactive protein (hsCRP), pulmonary function parameters, parathyroid hormone, and Tracp-5b. In multivariable regression analysis, hsCRP was the only independent determinant of TBS besides age and BMD. In contrast, independent determinants of BMD included body mass index and, to a lesser extent, 25-hydroxyvitamin D. CONCLUSION: Both BMD and TBS were independently associated with grade 2 or 3 vertebral fracture in COPD male subjects, involving distinct mechanisms. Systemic inflammation, as reflected by increased hsCRP levels, may be involved in deterioration of the trabecular microarchitecture in COPD-associated osteoporosis, whereas BMD decline is most strongly associated with weight loss. PMID- 29167971 TI - Abaloparatide-SC improves trabecular microarchitecture as assessed by trabecular bone score (TBS): a 24-week randomized clinical trial. AB - : In a phase 2 trial of 222 postmenopausal women with osteoporosis aged 55 to 85 years randomized to one of three different doses of abaloparatide-SC, subcutaneous teriparatide, or placebo for 24 weeks, abaloparatide-SC resulted in improvements in skeletal microarchitecture as measured by the trabecular bone score. INTRODUCTION: Subcutaneous abaloparatide (abaloparatide-SC) increases total hip and lumbar spine bone mineral density and reduces vertebral and non vertebral fractures. In this study, we analyzed the extent to which abaloparatide SC improves skeletal microarchitecture, assessed indirectly by trabecular bone score (TBS). METHODS: This is a post hoc analysis of a phase 2 trial of 222 postmenopausal women with osteoporosis aged 55 to 85 years randomized to abaloparatide-SC (20, 40, or 80 MUg), subcutaneous teriparatide (20 MUg), or placebo for 24 weeks. TBS was measured from lumbar spine dual X-ray absorptiometry (DXA) images in 138 women for whom the DXA device was TBS software compatible. Assessments were made at baseline, 12 and 24 weeks. Between-group differences were assessed by generalized estimating equations adjusted for relevant baseline characteristics, and a pre-determined least significant change analysis was performed. RESULTS: After 24 weeks, TBS increased significantly by 2.27, 3.14, and 4.21% versus baseline in participants on 20, 40, and 80 MUg abaloparatide-SC daily, respectively, and by 2.21% in those on teriparatide (p < 0.05 for each). The TBS in the placebo group declined by 1.08%. The TBS increase in each treatment group was significantly higher than placebo at 24 weeks (p < 0.0001 for each) after adjustment for age, BMI, and baseline TBS. A dose-response was observed at 24 weeks across the three doses of abaloparatide-SC and placebo (p = 0.02). The increase in TBS in the abaloparatide-SC 80 MUg group was significantly greater than TPTD (p < 0.03). CONCLUSIONS: These results are consistent with an effect of abaloparatide-SC to improve lumbar spine skeletal microarchitecture, as assessed by TBS.

PMID- 29167974 TI - Long-term outcome of vaginal mesh or native tissue in recurrent prolapse: a randomized controlled trial. AB - INTRODUCTION AND HYPOTHESIS: Our aim was to evaluate clinically relevant long term outcomes of transvaginal mesh or native tissue repair in women with recurrent pelvic organ prolapse (POP). METHODS: We performed a 7-year follow-up of a randomized controlled trial on trocar-guided mesh placement or native tissue repair in women with recurrent POP. Primary outcome was composite success, defined as absence of POP beyond the hymen, absence of bulge symptoms, and absence of retreatment for POP. Secondary outcomes were adverse events, pain, and dyspareunia. Multiple imputation was used for missing data of composite success and pain; estimates are presented with 95% confidence intervals (CI). RESULTS: Between August 2006 and July 2008, 194 women were randomized; 190 underwent surgery. At 7 years, 142 (75%) were available for analysis, of whom, the primary outcome could be calculated in 127. Composite success was 53% (95% CI 41, 66) for mesh and 54% (95% CI 42, 65) for native tissue. Repeat surgery for POP was 25% for mesh and 16% for native tissue (difference 9%; 95% CI -5, 23) and occurred in untreated compartments in the mesh group and treated compartments in the native tissue group. Mesh exposure rate was 42%; pain with mesh 39% and native tissue 50% (difference - 11%, 95% CI -27, 6); dyspareunia with mesh 20% and native tissue 17% (difference 3%, 95% CI -9, 17). CONCLUSIONS: Seven-year composite success rates appeared similar for mesh and native tissue. Mesh did not reduce long-term repeat surgery rates due to de novo POP in nonmesh-treated vaginal compartments. Mesh exposure rates were high, though significant differences in pain and dyspareunia were not detected. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov , NCT00372190. PMID- 29167975 TI - Use of an iPadTM application in preoperative counseling for pelvic reconstructive surgery: a randomized trial. AB - INTRODUCTION AND HYPOTHESIS: The goal of this study was to evaluate whether the addition of an iPadTM application to the informed consent process for pelvic organ prolapse (POP) surgery improves patient understanding and retention of information compared with standard verbal counseling (SVC) alone. METHODS: Patients scheduled for POP surgery were randomized to SVC alone or SVC augmented with an iPadTM application. Prior to counseling, immediately following counseling, and 6 weeks after surgery, patients completed a written quiz testing their understanding of POP and surgical repair (worst score 0; best score 20). Primary outcome was score change from pre- to immediately postcounseling. Secondary outcomes were patient satisfaction and score change from postcounseling to 6 weeks after surgery. Twenty-six patients per group were needed to detect a 2.8-point difference in score change between groups (80% power; alpha = 0.05). RESULTS: Sixty patients were randomized, and 57 patients (29 SVC; 28 iPad) were included in the final analysis. There was no significant difference in score change between groups immediately postcounseling. Six weeks after surgery, patients in the iPad group had more deterioration of score (iPad -4.0 +/- 2.8 vs. SVC -0.6 +/- 2.3 points; p = 0.02). Both groups reported similar satisfaction with counseling. CONCLUSIONS: The addition of a POP-based iPadTM application to the informed consent process for POP surgery did not improve patient comprehension immediately postcounseling and resulted in poorer retention of information 6 weeks after surgery compared with SVC alone. PMID- 29167976 TI - Temporary closure of colostomy with suture before colostomy takedown improves the postoperative outcomes. AB - PURPOSE: Temporary loop colostomy is a common surgical procedure used to avoid complications in high-risk distal anastomosis as well as pelvic inflammation. Issues regarding postoperative outcomes of colostomy takedown have been widely discussed in the literature, wound infection especially. Temporary closure of colostomy with suture before takedown was adopted in our study, which provided excellent traction to aid mobilization of stomy and avoided stool spillage to downgrade the wound classification to "clean contamination." We aimed to determine the effects of the procedure on postoperative outcomes. METHODS: This was a prospective case-control study at a single tertiary medical center. Patients presenting for elective colostomy takedown were included. Allis clamp (n = 50) or silk suture (n = 60) was applied to mobilize the colostomy, and results were compared. Operative time and wound infection rate were measured as primary postoperative outcomes. Univariate and multivariate analyses were used to demonstrate the association between the two groups and outcomes. RESULTS: In univariate analyses, significantly shorter operative time (median = 57 min, p = 0.003) and lower postoperative wound infection rate (3%, p = 0.03) were noted in the group receiving silk suture. Multivariate analyses results showed that silk suture was significantly associated with both operative time (B = - 8.5, p = 0.01) and wound infection (odds ratio = 0.18, p = 0.04). CONCLUSION: With the advantage of enhancing traction and decreasing contamination, the temporary closure of colostomy with suture improved takedown outcomes, including a shorter operative time and lower wound infection rate.

AB - Despite profound diagnostics, the aetiology of spinal epidural haematoma (SEH) often remains unknown. In this case, diagnostics revealed an SEH at the fifth and sixth thoracic levels due to a subclavian steal syndrome with a tortuous vascular loop between the sixth thoracic intercostal artery and the costocervical arteries deriving from the left subclavian artery with plump arteries in the epidural space. The patient underwent decompression surgery and a percutaneous transluminal angioplasty. The patient showed good recovery at follow-up. The SEH was a result of secondary formed thoracic collateral circuits with epidural involvement due to a subclavian steal syndrome. PMID- 29167978 TI - Long-term follow-up of multimodality treatment for multiple sclerosis-related trigeminal neuralgia. AB - BACKGROUND: The treatment for multiple sclerosis-related trigeminal neuralgia (MS TN) is less efficacious and associated with higher recurrence rates than classical TN. No consensus has been reached in the literature on the choice procedure for MS-TN patients. The aim of this study was to assess the incidence and surgical outcomes of medically refractory MS-TN. METHODS: Patient records were retrospectively reviewed for all Manitobans undergoing first procedure for medically refractory MS-TN between 2000 and 2014. Subsequent procedures were then recorded and analyzed in this subgroup of patients. The primary outcome measure was time to treatment failure. RESULTS: The incidence of medically refractory MS TN was 1.2/million/year. Twenty-one patients with 26 surgically treated sides underwent first rhizotomy including 13 GammaKnife and 13 percutaneous rhizotomies comprised of ten glycerol injections and three balloon compressions. Subsequent procedures were required on 23 sides (88%), including 24 GammaKnife, 19 glycerol injections, 25 balloon compressions, two microvascular decompressions, and four open partial surgical rhizotomies with a total of 99 surgeries on 26 sides (range, 1-12 each). CONCLUSIONS: The majority of MS-TN patients become medically refractory and require multiple repeat surgical procedures. MS-TN procedures were associated with high rates of pain recurrence and our data suggests reoperation within 1 year is often necessary. Optimal management strategy in this patient population remains to be determined. Patients need to be counseled on managing expectations as treatments commonly afford only temporary relief. PMID- 29167979 TI - Good results with minimally invasive unicompartmental knee resurfacing after 10 year follow-up. AB - The current study was designed to determine (1) 10-year implant survival and (2) patient's self-reported functional outcome in a single surgeon's consecutive cohort of patients who had undergone minimally invasive unicondylar resurfacing with a modified cementation technique utilizing a cobalt-chromium femur/inlaid all-PE tibia, fixed-bearing unicompartmental prosthesis. We included 344 consecutive patients (361 knees) who had received the study device between January 2002 and December 2005 in this retrospective study. After 10 years, 78 patients (78 knees) had died, 59 (59 knees) were lost to follow-up and four (four knees) did not participate. Thirteen knees (11 patients) were revised after a mean of 5.8 +/- 1.9 years. Hence, the study population at follow-up comprised 192 patients (207 knees). Ten-year implant survival was 94.6% (95% confidence interval, 90.9-96.8%). The Forgotten Joint Score and Oxford Knee Score were 68.9 +/- 28.9 and 39 +/- 9.1, respectively. Excellent survivorship and clinical outcomes were obtained with UKA with an inlaid all-PE tibia with a modified cementation technique. PMID- 29167980 TI - Role of isolated percutaneous autologous platelet concentrate in delayed union of long bones. AB - PURPOSE: The objective of this study is to evaluate the efficacy of percutaneous platelet concentrate (PC) injection in increasing the chances of attaining union in delayed union of long bones and to know whether the time taken for union decreases with use of PC. METHODS: Forty delayed unions (15-30 weeks old) were randomized into a study group in which autologous PC prepared by blood bank centrifuge was percutaneously injected at the fracture site under image intensifier after activation with 10% calcium gluconate and a control group where patients were observed over time. Follow-up was every 6 weeks till fracture union. At each follow-up visit clinical and radiological parameters of union were assessed. RESULTS: Percentage union was 78% (18/23) in PC group and 59% (10/17) in control group, respectively (p = 0.296). The mean time to fracture union treated with PC (15.33 +/- 9.91 weeks) was not different from the control group (13.10 +/- 7.21 weeks; p = 0.540). In the PC group union is seen in 12 weeks after PC injection in 60 per cent of the cases. CONCLUSION: Isolated percutaneous PC injection increases union rates in delayed union of long bones. The results were, however, not statistically significant but show high positive association. Further studies are required to recommend routine use of PC injection. PMID- 29167981 TI - Transcriptional induction of two phosphate transporter 1 genes and enhanced root branching in grape plants inoculated with Funneliformis mosseae. AB - We investigated the effects of the arbuscular mycorrhizal fungus (AMF) Funneliformis mosseae on the growth and root architecture of plantlets of the grape rootstock 41B MGt under hydroponic conditions, and analyzed the concomitant expression of putative mycorrhizal-specific phosphate transporter 1 (PHT1) genes. In vitro propagated plantlets were acclimatized to ex vitro culture before AMF inoculation and grown under low phosphate (Pi) nutrition conditions during 6 weeks. Grape roots could be efficiently colonized by F. mosseae in this culture system, as shown by high mycorrhization frequency and intensity. The presence of many arbuscules in the cortex was coupled with high-level expression of two PHT1 genes in grape roots. These two very similar genes, named VvPht1-1 and VvPht1-2, present P1BS and MYCS regulatory motifs in their promoter, consistent with a specific role in the mycorrhizal pathway of Pi uptake. Although AMF inoculation significantly increased shoot growth, no effect on root biomass was observed. However, inoculated grapes exhibited an enhanced branched root system compared with non-inoculated controls, with a twofold higher number of tips and a higher proportion of fine roots usually involved in nutrient uptake from the soil. Taken together, these results suggest that root colonization by F. mosseae improved grape growth by favoring the uptake of Pi from the substrate via VvPht1-1 and VvPht1-2 high-level expression. PMID- 29167982 TI - Successional changes in trophic interactions support a mechanistic model of post fire population dynamics. AB - Models based on functional traits have limited power in predicting how animal populations respond to disturbance because they do not capture the range of demographic and biological factors that drive population dynamics, including variation in trophic interactions. I tested the hypothesis that successional changes in vegetation structure, which affected invertebrate abundance, would influence growth rates and body condition in the early-successional, insectivorous gecko Nephrurus stellatus. I captured geckos at 17 woodland sites spanning a succession gradient from 2 to 48 years post-fire. Body condition and growth rates were analysed as a function of the best-fitting fire-related predictor (invertebrate abundance or time since fire) with different combinations of the co-variates age, sex and location. Body condition in the whole population was positively affected by increasing invertebrate abundance and, in the adult population, this effect was most pronounced for females. There was strong support for a decline in growth rates in weight with time since fire. The results suggest that increased early-successional invertebrate abundance has filtered through to a higher trophic level with physiological benefits for insectivorous geckos. I integrated the new findings about trophic interactions into a general conceptual model of mechanisms underlying post-fire population dynamics based on a long-term research programme. The model highlights how greater food availability during early succession could drive rapid population growth by contributing to previously reported enhanced reproduction and dispersal. This study provides a framework to understand links between ecological and physiological traits underlying post-fire population dynamics. PMID- 29167983 TI - Climate change can alter predator-prey dynamics and population viability of prey. AB - For many organisms, climate change can directly drive population declines, but it is less clear how such variation may influence populations indirectly through modified biotic interactions. For instance, how will climate change alter complex, multi-species relationships that are modulated by climatic variation and that underlie ecosystem-level processes? Caribou (Rangifer tarandus), a keystone species in Newfoundland, Canada, provides a useful model for unravelling potential and complex long-term implications of climate change on biotic interactions and population change. We measured cause-specific caribou calf predation (1990-2013) in Newfoundland relative to seasonal weather patterns. We show that black bear (Ursus americanus) predation is facilitated by time-lagged higher summer growing degree days, whereas coyote (Canis latrans) predation increases with current precipitation and winter temperature. Based on future climate forecasts for the region, we illustrate that, through time, coyote predation on caribou calves could become increasingly important, whereas the influence of black bear would remain unchanged. From these predictions, demographic projections for caribou suggest long-term population limitation specifically through indirect effects of climate change on calf predation rates by coyotes. While our work assumes limited impact of climate change on other processes, it illustrates the range of impact that climate change can have on predator-prey interactions. We conclude that future efforts to predict potential effects of climate change on populations and ecosystems should include assessment of both direct and indirect effects, including climate-predator interactions. PMID- 29167984 TI - X-ray micro-computed-tomography in pediatric surgery: a new tool for studying embryos. AB - PURPOSE: The embryology of common congenital malformations is discussed controversially. Studies are hampered by a shortage of study material and techniques which require partial or complete preparation and therewith destruction of embryos. X-ray micro-computed-tomography (uCT) is a technical opportunity keeping the embryos intact. Thus, the aim of this study was to assess the applicability of uCT in embryonic research compared to the anatomical information obtained by scanning electron microscopy (SEM). METHODS: Chicken, rat, mouse and sheep embryos, processed either for SEM studies or as whole embryos, were imaged in three-dimensional (3D) using uCT. The obtained two dimensional (2D) digital datasets were volume rendered by tomographic reconstruction software and studied using analysis software. RESULTS: All embryos were uCT scanned without technical problems. The quality of the uCT images (image contrast, anatomical details) was excellent, but varied depending on age and species studied. uCT imaging allowed a more comprehensive anatomical/morphological analysis but showed less surface details compared to SEM. CONCLUSION: uCT is a technique suitable and innovative for pediatric surgical research, which allows detailed evaluation of entire embryos without time- and specimen-consuming micro-dissection. Samples prepared for SEM can be used for uCT and vice versa. PMID- 29167985 TI - Short-term outcome after cystectomy: comparison of early oral feeding in an enhanced recovery protocol and feeding using Bengmark nasojejunal tube. AB - PURPOSE: Cystectomy for bladder cancer is associated with a high risk of postoperative complications. Standardized perioperative protocols, such as enhanced recovery after surgery (ERAS) protocols, aim to improve postoperative outcome. Postoperative feeding strategies are an important part of these protocols. In this two-centre study, we compared complications and length of hospital stay (LOS) between an ERAS protocol with early oral nutrition and a protocol with early enteral feeding with a Bengmark nasojejunal tube. METHODS: We retrospectively reviewed 154 consecutive patients who underwent cystectomy for bladder cancer in two hospitals (Hospital A and B) between 2014 and 2016. Hospital A uses an ERAS protocol (n = 45), which encourages early introduction of an oral diet. Hospital B uses a fast-track protocol comprising feeding with a Bengmark nasojejunal tube (Bengmark-protocol, n = 109). LOS and complications according to Clavien classification were compared between protocols. RESULTS: Overall 30-day complication rates in the ERAS and Bengmark protocol were similar (64.4 and 67.0%, respectively; p = 0.463). The rate of postoperative ileus (POI) was significantly lower in the Bengmark protocol (11.9% vs. 34.4% in the ERAS protocol, p = 0.009). This association remained significant after adjustment for other variables (odds ratio 0.32, 95% confidence interval 0.11-0.96; p = 0.042). Median LOS did not differ significantly between protocols (10 days vs. 11 days in the ERAS and Bengmark protocols, respectively; p = 0.861). CONCLUSIONS: Early oral nutrition in Hospital A was well tolerated. However, the Bengmark protocol was superior with respect to occurrence of POI. A prospective study may clarify whether the lower rate of POI was due to the use of early nasojejunal tube feeding or other reasons. PMID- 29167986 TI - Amidase activity is essential for medial localization of AmiC in Caulobacter crescentus. AB - Bacterial cell division is a complex process brought about by the coordinated action of multiple proteins. Separation of daughter cells during the final stages of division involves cleavage of new cell wall laid down at the division septum. In E. coli, this process is governed by the action of N-acetylmuramoyl-L-alanine amidases AmiA/B/C, which are regulated by their LytM activators EnvC and NlpD. While much is known about the regulation of septum cleavage in E. coli, the mechanism of daughter cell separation is not clear in Caulobacter crescentus, a dimorphic crescent-shaped bacterium. In this work, we characterized the role of AmiC, the only annotated amidase in C. crescentus. AmiC from C. crescentus is functional in E. coli and restores cell separation defects seen in E. coli amidase mutants, suggesting that AmiC has septum splitting activity. The medial localization of AmiC was independent of DipM, an LytM domain-containing endopeptidase. Our results indicate that enzymatic activity is essential for medial recruitment of AmiC. Overexpression of AmiC causes cell separation defects and formation of chains. Finally, overexpression of AmiC in cells inhibited for cell division leads to lysis. Collectively, our findings reveal that regulation of daughter cell separation in C. crescentus differs from that of E. coli and can serve as a model system to study bacterial cytokinesis. PMID- 29167987 TI - The geographical vector in distribution of genetic diversity for Clonorchis sinensis. AB - Clonorchis sinensis, the causative agent of clonorchiasis, is one of the most important parasites that inhabit countries of East and Southeast Asia. In this study, we validated the existence of a geographical vector for C. sinensis using the partial cox1 mtDNA gene, which includes a conserved region. The samples of parasite were divided into groups corresponding to three river basins, and the size of the conserved region had a strong tendency to increase from the northernmost to the southernmost samples. This indicates the availability of the geographical vector in distribution of genetic diversity. A vector is a quantity that is characterized by magnitude and direction. Geographical vector obtained in cox1 gene of C. sinensis has both these features. The reasons for the occurrence of this feature, including the influence of intermediate and definitive hosts on vector formation, and the possibility of its use for clonorchiasis monitoring are discussed.

AB - Fullerenes are the most popular molecules to use in applications related to molecular electronics because of their superconductive nature. These molecules show a diverse range of properties, including optical, electronic, and structural characteristics. In this work, we focused on the electronic transport properties of molecular devices consisting of the fullerene B40 or B40 with different anchor atoms between two gold electrodes in a two-probe configuration. The elements used as anchor atoms in the B40 molecules were oxygen, selenium, and sulfur, i.e., chalcogens. The current characteristics of these fullerene-based molecular devices were calculated and analyzed. The analysis highlighted the superior electrical conductivity of the pure B40 device compared to the devices based on its chalcogen-anchored variants. The conductivities of the molecular devices were ranked as follows: pure B40 > selenium-anchored > sulfur-anchored > oxygen anchored B40. It was also noted that the devices based on B40 and its chalcogen anchored variants gave nonzero conductance values at zero bias. These results pave the way for the application of these molecules in future nanodevices utilizing extremely small bias voltages. PMID- 29167989 TI - TCNE-modified graphene as an adsorbent for N2O molecule: a DFT study. AB - Adsorption behavior of nitrous oxide (N2O) on pristine graphene (PG) and tetracyanoethylene (TCNE) modified PG surfaces is investigated using density functional theory. A number of initial adsorbate geometries are considered on both surfaces and the most stable ones are chosen upon calculation of the adsorption energies (Eads). N2O is found to adsorb in a weakly exoergic process (Eads ~ -3.18 kJ mol-1) at the equilibrium distance of 3.52 A on the PG surface. N2O adsorption can be greatly enhanced with the presence of a TCNE molecule (Eads = -87.00 kJ mol-1). Mulliken charge analysis confirms that adsorption of N2O is not accompanied by distinct charge transfer from the surfaces to the molecule (? 0.001 ?e? for each case). Moreover, on the basis of calculated changes in the HOMO/LUMO energy gap, it is found that electronic properties of PG and TCNE modified PG are not sensitive toward adsorption of N2O, indicating that both surfaces are not good enough to introduce as an N2O detector. However, the considerable amount of Eads in TCNE modified PG can be a guide to the design of graphene-based adsorbents for N2O capture. PMID- 29167991 TI - A comparison of bioclimatic potential in two global regions during the late twentieth century and early twenty-first century. AB - Changes in the general circulation of the atmosphere have been taking place during the latter part of the twentieth century and the early part of the twenty first century. In the Belgorod region of Southwest Russia, this has been manifested in the more frequent occurrence of stationary anticyclones, including those referred to as blocking anticyclones, especially during the summer season. Also, there has been a general increase in regional temperatures during the growing season over the period mentioned above, and combined with the more frequent occurrence of anticyclones has led to less humid conditions. In the Missouri region of the Central USA, variability in the circulation on differing time scales within the Eastern Pacific plays a strong role in the conditions that impact the growing season. As a result of changes in climate and climate variability, the benefit to agriculture during this period produces mixed results for both regions. This work will evaluate the growing season conditions using indexes that combine growing season temperature and precipitation such as the hydrothermal coefficient (HTC) and the bioclimatic potential (BCP). Also, the interannual variability of these indexes in both regions was examined. In the Belgorod region, the increase in temperature combined with little change in precipitation produced mixed results in interpreting these indexes. This was accompanied by more variable conditions as revealed by these indexes in the early twenty-first century. In the Missouri region, there was little trend in either index over the time period and the tendency was toward less climatic variability in the HTC and BCP. PMID- 29167990 TI - Histologic analysis has a prognostical value in colorectal biopsies assessed for suspicion of graft-versus-host disease. AB - Gastrointestinal (GI) graft-versus-host-disease (GVHD) is a common and severe complication of allogeneic hematopoietic stem cell transplantation, but clinical and histological features are unspecific. The aim of this study was to correlate the histological GI GVHD grade with the clinical outcomes. In a retrospective study of 112 patients with clinically suspected GI GVHD, colonic biopsies were reviewed by three pathologists without knowledge of the corresponding clinical data and classified in four scores, according to the NIH Consensus Project recommendations: no GVHD, possible, probable, and unequivocal GVHD. At the end of the study, the histological and clinical data were confronted with the following results: clinical diagnosis of GI GVHD was established for 70 patients (62.5%) and histological scores correlated well with the clinical diagnosis (p < 0.001) and particularly with the prognosis (p < 0.05).When severe lesions were observed, the 1 year overall survival declined to 9%. None of the features reported in the literature to support GVHD diagnosis, eosinophil count, endocrine cells aggregate, immunohistochemical analysis (cytomegalovirus, CD123, chromogranin), did not help us for diagnosis. So routine histopathology alone without immunohistochemistry is a strong and reproducible tool to diagnose GI GVHD with the help of clinical and biological information, and most importantly, histological grading proved to be a powerful prognostic value. PMID- 29167992 TI - Slow correction of severe spastic hyperlordosis in an adult by means of magnetically expandable rods. AB - BACKGROUND: We describe a case of severe and progressive lumbar hyperlordosis (160 degrees ) in a 28-year-old female university student with cerebral palsy. Her main complaints were abdominal wall pain and increasing inability to sit in her custom wheelchair. METHOD: When deciding on our opinion about the most promising treatment strategy, we contemplated slow continued correction by means of percutaneously expandable magnetic rods (MAGEC) after the index surgery as a key component of a satisfactory correction in this severe and rigid curve. After an initial radical release and partial correction, a release and correction procedure was required for the bilateral hip flexion contracture. A final in situ posterior fusion was performed as a second spinal procedure, once the desired final correction at 66 degrees of lumbar lordosis was achieved. RESULT: Three years after the completion of surgery, the patient has a stable clinical and radiological result as well as a solid posterior fusion on CT. CONCLUSION: This is the first case published in which percutaneous magnetic distraction was successfully used in an adult patient. PMID- 29167993 TI - Group 3 medulloblastoma in a patient with a GYS2 germline mutation and glycogen storage disease 0a. AB - Glycogen storage disease (GSD) 0a is a rare congenital metabolic disease with symptoms in infancy and childhood caused by biallelic GYS2 germline variants. A predisposition to cancer has not been described yet. We report here a boy with GSD 0a, who developed a malignant brain tumor at the age of 4.5 years. The tumor was classified as a group 3 medulloblastoma, and the patient died from cancer 27 months after initial tumor diagnosis. This case appears interesting as group 3 medulloblastoma is so far not known to arise in hereditary syndromes and the biology of sporadic group 3 medulloblastoma is largely unknown. PMID- 29167994 TI - Congenital Zika virus infection: a neuropathological review. AB - BACKGROUND: A relationship between Zika virus (ZikV) infection in pregnancy and the occurrence of microcephaly was established during the Zika outbreak in Brazil (2015-2016). Neuropathological findings in congenital Zika syndrome helped to understand its pathogenetic mechanisms. RESULTS: The most relevant postmortem findings in the central nervous system (CNS) of fetuses and neonates infected with ZikV early in gestation are microcephaly with ex-vacuo ventriculomegaly and large head circumference associated with obstructive hydrocephalus due to severe midbrain and aqueduct distortion. Babies with severe brain lesions are born with arthrogryposis. Histologically, there is extensive destruction of the hemispheric parenchyma, calcifications, various disturbances of neuronal migration, reactive gliosis, microglial hyperplasia and occasional perivascular cuffs of lymphocytes, also in the meninges. Hypoplastic lesions secondary to the lack of descending nerve fibers include small basis pontis, pyramids and spinal corticospinal tracts. Cerebellar hypoplasia is also common. Severe nerve motor nerve cell loss is observed in the anterior horn of the spinal cord. CONCLUSION: A spectrum of neuropathological changes, from severe microcephaly to obstructive hydrocephalus was observed. The severity of the lesions is directly related to the gestational age, the most severe occurring when the mother is infected in the first trimester. Infection of progenitor cells at the germinal matrix was demonstrated. The lack of spinal motor neurons is responsible for fetal acynesia and consequent arthrogryposis. PMID- 29167995 TI - Ultrasound-guided placement of ventricular catheters in first-time pediatric VP shunt surgery. AB - PURPOSE: Ventriculo-peritoneal (VP) shunts are effective for treatment of hydrocephalus in all age groups; however, they are associated with complications, a common one being ventricular catheter (VC) obstruction. VC position is likely to influence VC survival; however, most VCs are positioned freehand without guidance. This paper describes the accuracy of ultrasound guidance for VC placement and the impact of tip location on VC occlusion rate. METHODS: This is a retrospective cohort study of hydrocephalic children with first-time VP shunt and ultrasound-guided VC placement. Data recorded were age, sex, cause of hydrocephalus, side (left or right) and location (frontal or occipital) of VC, and exact postoperative position within the ventricle on first postoperative imaging: middle of ventricle (optimal position), near or touching the medial or lateral ventricle wall, within the third ventricle, and at the contralateral side. RESULTS: Of the 128 screened patients, 85 had a first postoperative imaging that clearly defined the VC position and were included. The follow-up was at least 12 months. Seventy-three percent of VCs were placed on the right and 71% via a frontal burhole. Eighty-three of 85 VC tips (95%) were in the intended ventricle, 61% at optimal position. Nine of 85 VCs (10%) obstructed within the first 12 months. Seven of nine (78%) obstructed VCs were located in a nonoptimal position (p = 0.016). Two of nine (22%) obstructed VCs entered through a frontal and seven of nine (78%) through an occipital burrhole (p = 0.016). CONCLUSION: Ultrasound-guided VC placement is as precise as frameless navigated placement. The optimal VC position was associated to a significant lower VC obstruction rate. The frontal position was superior to the occipital. Intraoperative US guidance is fast with almost no extra time and no extra cost. US-guided VC placement should become standard of care in VP shunt surgery. PMID- 29167996 TI - Unexpected finding: dermoid component within a filar lipoma. PMID- 29167997 TI - The association of kyphosis assessed in supine and standing positions with future activities of daily living dependence: the Kurabuchi Study. AB - : We investigated the longitudinal association of noninvasively evaluated kyphotic posture with future dependence in activities of daily living and death in a community-dwelling older Japanese. We found that the association with outcomes varied according to the types of kyphotic posture. INTRODUCTION: We have previously found an association between severe kyphosis and future dependence in activities of daily living (ADL) in people who manifest the condition in the supine position (structural curvature). However, because some people show severe kyphosis only in the standing position (postural curvature), we combined our noninvasively obtained kyphosis measurements from participants in the supine position (block method) with those obtained from participants in the standing position (kyphosis index) to determine whether not only structural curvature but also postural curvature is associated with ADL dependence and death. METHODS: Between 2005 and 2006, we carried out health evaluations of adults aged 65 years or older in Kurabuchi Town, Japan: 792 participants (337 males, 455 females) who were independent in ADL at baseline and underwent evaluation of kyphotic posture were followed up until March 2014 (mean follow-up: 7.5 years). Participants who experienced one or more admissions to a nursing home, certification of a need for long-term care/support, or a decline in the Katz ADL Index during the follow-up period were defined as being dependent in ADL. RESULTS: A flat back (straight spine in a standing position) and structural curvature were associated with future ADL dependence, but postural curvature was not. The multivariate-adjusted odds ratios (95% confidence interval) compared with physiological curvature (physiological curvature in a standing position) as the reference were 1.72 (1.04 2.86) for a flat back and 2.76 (1.59-4.79) for structural curvature. A weak association with death was observed in those with structural curvature. CONCLUSIONS: Our results suggest that the prognoses of people with kyphosis differ according to the type of kyphotic posture. PMID- 29167998 TI - Association of stroke subtypes with risk of hip fracture: a population-based study in Taiwan. AB - : Stroke is a critical issue of physical disability. This study aimed to investigate the association of stroke subtypes and hip fracture by using the Taiwan National Health Insurance Research Database. Significantly higher risks of hip fracture were found for female gender and intracerebral hemorrhagic stroke patients. INTRODUCTION: Previous studies reported the increased hip fracture (HF) after acute stroke. Increased falling tendency immobilization-related sarcopenia and underlying comorbidities are related to HF in stroke patients. In the present study, we explored the association of different stroke subtypes and several comorbidities with poststroke HF. METHODS: A population-based study was conducted using National Health Insurance Research Database (NHIRD) of Taiwan. First, we identified 17,168 patients diagnosed as having a stroke between January 1, 2002, and December 31, 2010. Then, we randomly selected 51,504 controls that never had a stroke and matched these controls to stroke patients in a 1:3 ratio by age (+/- 1 year old) and gender. Cox proportional hazards model was used to estimate hazard ratio (HR) and 95% confidence interval (CI). RESULTS: Stroke patients had a significantly higher risk of HF (HR = 1.69). Female and male stroke patients had incidence rate ratios (IRRs) of 2.05 and 1.82 for HF, respectively. Significantly increased IRRs of 1.82, 1.52, and 2.63 for HF were found for stroke patients with 0, 1, and >= 2 comorbidities, respectively. All stroke patients, ischemic stroke patients, and intracerebral hemorrhagic (ICH) patients had HF risks of 1.65, 1.60, and 2.34, respectively. CONCLUSION: Overall, stroke significantly increases the incidence of HF, and the risk of HF is significantly higher in ICH patients and female gender. We should identify stroke patients at risk of HF and pay more attention to prevent them from fall in poststroke long term care. PMID- 29167999 TI - Integrated Analysis of Healthcare Efficiency: A Systematic Review. AB - Data Envelopment Analysis (DEA) has been used as a performance measurement tool in efficiency assessment of healthcare systems. However, over the years, researchers and health practitioners presented the theoretical and methodological limitations of DEA that limits the full view of healthcare efficiency. To address these limitations, a commonly used strategy is to integrate other statistical methods and techniques with DEA to provide better efficiency evaluation. This paper reviews 57 studies with DEA applications in the healthcare industry to illustrate the integrated analysis of healthcare efficiency. With DEA as the central method, regression models in conjunction with statistical tests are commonly used. Input-oriented radial DEA models using predominantly capacity related inputs and activity-related outputs and following either constant return to scale or variable return to scale assumptions are mostly applied to measure healthcare efficiency. PMID- 29168000 TI - Raman Mapping Analysis of Graphene-Integrated Silicon Micro-Ring Resonators. AB - We present a Raman mapping study of monolayer graphene G and 2D bands, after integration on silicon strip-waveguide-based micro-ring resonators (MRRs) to characterize the effects of the graphene transfer processes on its structural and optoelectronic properties. Analysis of the Raman G and 2D peak positions and relative intensities reveal that the graphene is electrically intrinsic where it is suspended over the MRR but is moderately hole-doped where it sits on top of the waveguide structure. This is suggestive of Fermi level 'pinning' at the graphene-silicon heterogeneous interface, and we estimate that the Fermi level shifts down by approximately 0.2 eV from its intrinsic value, with a corresponding peak hole concentration of ~ 3 * 1012 cm-2. We attribute variations in observed G peak asymmetry to a combination of a 'stiffening' of the E 2g optical phonon where the graphene is supported by the underlying MRR waveguide structure, as a result of this increased hole concentration, and a lowering of the degeneracy of the same mode as a result of localized out-of-plane 'wrinkling' (curvature effect), where the graphene is suspended. Examination of graphene integrated with two different MRR devices, one with radii of curvature r = 10 MUm and the other with r = 20 MUm, indicates that the device geometry has no measureable effect on the level of doping. PMID- 29168001 TI - Pronounced Photovoltaic Response from Multi-layered MoTe2 Phototransistor with Asymmetric Contact Form. AB - In this study, we fabricate air-stable p-type multi-layered MoTe2 phototransistor using Au as electrodes, which shows pronounced photovoltaic response in off-state with asymmetric contact form. By analyzing the spatially resolved photoresponse using scanning photocurrent microscopy, we found that the potential steps are formed in the vicinity of the electrodes/MoTe2 interface due to the doping of the MoTe2 by the metal contacts. The potential step dominates the separation of photoexcited electron-hole pairs in short-circuit condition or with small V sd biased. Based on these findings, we infer that the asymmetric contact cross section between MoTe2-source and MoTe2-drain electrodes is the reason to form non zero net current and photovoltaic response. Furthermore, MoTe2 phototransistor shows a faster response in short-circuit condition than that with higher biased V sd within sub-millisecond, and its spectral range can be extended to the infrared end of 1550 nm.

AB - This paper demonstrates the lasing and transport properties of a green conjugated polymer, namely POFP. High photoluminescence yields and excellent electron transport of POFP film make it promising for gain media. Low threshold value of 4.0 MUJ/cm2 for amplified spontaneous emissions under a pulsed Nd:YAG laser at 355 nm was obtained, as well as a high Q-factor of 159. An inverted waveguide microcavity scheme has been developed to fabricate diode-pumped organic solid lasers (OSLs) using POFP. Gain narrowing with significant radiance increase was observed in the devices, giving evidence of the interference enhancement induced by microcavity and the lasing properties of POFP. PMID- 29168003 TI - Numerical Study of an Efficient Solar Absorber Consisting of Metal Nanoparticles. AB - We propose and theoretically investigate an efficient solar light absorber based on a multilayer structure consisting of tungsten nanoparticle layers and SiO2 layers. According to our calculation, average absorbance over 94% is achieved in the wavelength range between 400 and 2500 nm for the proposed absorber. The excellent performance of the absorber can be attributed to the localized surface plasmon resonance as well as the Fabry-Perot resonance among the metal-dielectric metal layers. We compare the absorbing efficiency of tungsten nanosphere absorber with absorbers consisting of the other metal nanoparticles and conclude that iron can be an alternative material for tungsten in solar energy systems for its excellent absorbing performance and the similar optical properties as tungsten. Besides, a flat multilayer absorber is designed for comparison, and it is also proved to have a good absorbing performance for solar light. PMID- 29168004 TI - Diffusion-weighted imaging of the prostate: should we use quantitative metrics to better characterize focal lesions originating in the peripheral zone? AB - PURPOSE: To compare inter-reader concordance and accuracy of qualitative diffusion-weighted (DW) PIRADSv2.0 score with those of quantitative DW-MRI for the diagnosis of peripheral zone prostate cancer. MATERIALS AND METHODS: Two radiologists independently assigned a DW-MRI-PIRADS score to 92 PZ-foci, in 74 patients (64.3+/-5.6 years old; median PSA level: 8 ng/ml, normal DRE in 70 men). A standardised ADCmean and nine ADC-derived parameters were measured, including ADCratios with the whole-prostate (WP-ADCratio) or the mirror-PZ (mirror ADCratio) as reference areas. Surgical histology and MRI-TRUS fusion-biopsy were the reference for tumours and benign foci, respectively. Inter-reader agreement was assessed by the Cohen-kappa-coefficient and the intraclass correlation coefficient (ICC). Univariate-multivariate regressions determined the most predictive factor for cancer. RESULTS: Fifty lesions were malignant. Inter-reader concordance was fair for qualitative assessment, but excellent for quantitative assessment for all quantitative variables. At univariate analysis, ADCmean, WP ADCratio and WL-ADCmean performed equally, but significantly better than the mirror-ADCratio (p<0.001). At multivariate analysis, the only independent variable significantly associated with malignancy was the whole-prostate ADCratio. At a cut-off value of 0.68, sensitivity was 94-90 % and specificity was 60-38 % for readers 1 and 2, respectively. CONCLUSION: The whole-prostate ADCratio improved the qualitative inter-reader concordance and characterisation of focal PZ-lesions. KEY POINTS: * Inter-reader concordance of DW PI-RADSv2.0 score for PZ lesions was only fair. * Using a standardised ADCmean measurement and derived DW-quantitative parameters, concordance was excellent. * The whole prostate ADCratio performed significantly better than the mirror-ADCratio for cancer detection. * At a cut-off of 0.68, sensitivity values of WP-ADCratio were 94-90 %. * The whole-prostate ADCratio may circumvent variations of ADC metrics across centres. PMID- 29168005 TI - A survey by the European Society of Breast Imaging on the utilisation of breast MRI in clinical practice. AB - OBJECTIVES: While magnetic resonance imaging (MRI) is considered a helpful diagnostic tool in breast imaging, discussions are ongoing about appropriate protocols and indications. The European Society of Breast Imaging (EUSOBI) launched a survey to evaluate the utilisation of breast MRI in clinical practice. METHODS: An online survey reviewed by the EUSOBI board and committees was distributed amongst members. The questions encompassed: training and experience; annual breast MRI and MRI-guided-intervention workload; examination protocols; indications; reporting habits and preferences. Data were summarised and subgroups compared using chi2 test. RESULTS: Of 647 EUSOBI members, 177 (27.4%) answered the survey. The majority were radiologists (90.5%), half of them based in academic centres (51.9%). Common indications for MRI included cancer staging, treatment monitoring, high-risk screening and problem-solving, and differed significantly between countries (p<=0.03). Structured reporting and BI-RADS were mostly used. Breast radiologists with <=10 years of experience preferred inclusion of additional techniques, such as T2/STIR (p=0.03) and DWI (p=0.08) in the scan protocol. MRI-guided interventions were performed by a minority of participants (35.4%). CONCLUSIONS: The utilisation of breast MRI in clinical practice is generally in line with international recommendations. There are substantial differences between countries. MRI-guided interventions and functional MRI parameters are not widely available. KEY POINTS: * MRI is commonly used for the detection and characterisation of breast lesions. * Clinical practice standards are generally in line with current recommendations. * Standardised criteria and diagnostic categories (mainly BI-RADS) are widely adopted. * Younger radiologists value additional techniques, such as T2/STIR and DWI. * MRI-guided breast biopsy is not widely available. PMID- 29168006 TI - Breast lesions classified as probably benign (BI-RADS 3) on magnetic resonance imaging: a systematic review and meta-analysis. AB - PURPOSE: To investigate prevalence, malignancy rates, imaging features, and follow-up intervals for probably benign (BI-RADS 3) lesions on breast magnetic resonance imaging (MRI). METHODS: A systematic database-review of articles published through 22/06/2016 was performed. Eligible studies reported BI-RADS 3 lesions on breast MRI. Two independent reviewers performed a literature review and data extraction. Data collection included study characteristics, number/type of BI-RADS 3 lesions, final diagnosis (histopathology and/or follow-up). Sources of bias (QUADAS-2) were assessed. Meta-analysis included data-pooling, heterogeneity testing, and meta-regression. RESULTS: Fifteen studies were included. Prevalence was reported in 11 studies (range: 1.2-24.3%). Malignancy rates ranged between 0.5-10.1% (pooled 61/2814, 1.6%, 95%-CI:0.9-2.3% (random effects-model), I2=53%, P=0.007). In a subgroup of 11 studies (2183 lesions), highest malignancy rates were observed in non-mass lesions (pooled 25/714, 2.3%, 95%-CI:0.8-3.9%, I2=52%, P=0.021) followed by mass lesions (pooled 15/771, 1.5%, 95%-CI:0.7-2.4%, I2=0%, P=0.929), and foci (pooled 10/698, 1%, 95%-CI:0.3-1.7%, I2=0%, P=0.800). There was non-significant negative association between prevalence and malignancy rates (P=0.077). Malignant lesions were diagnosed at all follow-up time points. CONCLUSION: While prevalence of MRI BI-RADS 3 lesions was strongly heterogeneous, pooled malignancy rates met BI-RADS benchmarks (<2%). Malignancy rates varied, exceeding 2% in non-mass lesions. Twenty-four-month surveillance is required to detect all malignant lesions. KEY POINTS: * Probably benign (BI-RADS 3) lesions showed a pooled malignancy-rate of 1.6% (95%-CI:0.9 2.3%). * Malignancy rates differ and are highest in non-mass lesions (2.3%, 95% CI:0.8-3.9%). * The prevalence of BI-RADS 3 lesions on breast MRI ranged from 1.2 24.3%. * Malignant lesions were diagnosed at follow-up time points up to 24 months. PMID- 29168007 TI - Can dual-energy CT replace perfusion CT for the functional evaluation of advanced hepatocellular carcinoma? AB - OBJECTIVES: To determine the degree of relationship between iodine concentrations derived from dual-energy CT (DECT) and perfusion CT parameters in patients with advanced HCC under treatment. METHODS: In this single-centre IRB approved study, 16 patients with advanced HCC treated with sorafenib or radioembolization who underwent concurrent dynamic perfusion CT and multiphase DECT using a single source, fast kV switching DECT scanner were included. Written informed consent was obtained for all patients. HCC late-arterial and portal iodine concentrations, blood flow (BF)-related and blood volume (BV)-related perfusion parameters maps were calculated. Mixed-effects models of the relationship between iodine concentrations and perfusion parameters were computed. An adjusted p value (Bonferroni method) < 0.05 was considered significant. RESULTS: Mean HCC late arterial and portal iodine concentrations were 22.7+/-12.7 mg/mL and 18.7+/-8.3 mg/mL, respectively. Late-arterial iodine concentration was significantly related to BV (mixed-effects model F statistic (F)=28.52, p<0.0001), arterial BF (aBF, F=17.62, p<0.0001), hepatic perfusion index (F=28.24, p<0.0001), positive enhancement integral (PEI, F=66.75, p<0.0001) and mean slope of increase (F=32.96, p<0.0001), while portal-venous iodine concentration was mainly related to BV (F=29.68, p<0.0001) and PEI (F=66.75, p<0.0001). CONCLUSIONS: In advanced HCC lesions, DECT-derived late-arterial iodine concentration is strongly related to both aBF and BV, while portal iodine concentration mainly reflects BV, offering DECT the ability to evaluate both morphological and perfusion changes. KEY POINTS: * Late-arterial iodine concentration is highly related to arterial BF and BV. * Portal iodine concentration mainly reflects tumour blood volume. * Dual energy CT offers significantly decreased radiation dose compared with perfusion CT. PMID- 29168009 TI - Dietary lipophilic iron accelerates regional brain iron-load in C57BL6 mice. AB - Impaired brain iron homeostatic mechanisms, independent of pathological hallmarks, are harmful to the brain because excess free iron can cause DNA, protein, and lipid damage via oxidative stress. The goal of this study was to evaluate the longitudinal effect of chronic iron overload and deficiency in the vertebrate brain. Ten-week-old C57BL6 male mice were randomly assigned to one of four unique dietary regiments for 1 year: iron-deficient, normal iron, and two different concentrations of lipophilic iron diet containing 3,5,5 trimethylhexanoyl ferrocene (TMHF). Longitudinal MRI parametrics were used to assess the location and extent of ferric iron distribution. Tissue collected at 12 months was used to directly measure iron-load, protein alterations, and histological metrics. While the iron-deficient diet did not alter brain iron stores, 0.11% TMHF and early exposure with 0.5% TMHF elevated brain iron by roughly 40 and 100%, respectively. R 2 rate increased more in the TMHF groups within iron rich brain regions. Increased brain iron concentration was linearly correlated with an increase in L-ferritin expression, and TMHF diet was found to increase L-ferritin within the olfactory bulb, neocortex, pallidum, thalamus, corpus callosum, CA3 regions of the hippocampus, and substantia nigra. Moreover, gliosis and oxidative stress were detected in the TMHF groups in the regions associated with iron-load. Spatial memory impairment was evident in the iron loaded mice. This work illustrates that lipophilic iron elevates brain iron in a regionally specific fashion and positions dietary TMHF administration as a model for brain iron overloading. PMID- 29168008 TI - GABAA receptor subunit deregulation in the hippocampus of human foetuses with Down syndrome. AB - The function, regulation and cellular distribution of GABAA receptor subunits have been extensively documented in the adult rodent brain and are linked to numerous neurological disorders. However, there is a surprising lack of knowledge on the cellular (sub-) distribution of GABAA receptor subunits and of their expressional regulation in developing healthy and diseased foetal human brains. To propose a role for GABAA receptor subunits in neurodevelopmental disorders, we studied the developing hippocampus of normal and Down syndrome foetuses. Among the alpha1-3 and gamma2 subunits probed, we find significantly altered expression profiles of the alpha1, alpha3 and gamma2 subunits in developing Down syndrome hippocampi, with the alpha3 subunit being most affected. alpha3 subunits were selectively down-regulated in all hippocampal subfields and developmental periods tested in Down syndrome foetuses, presenting a developmental mismatch by their adult-like distribution in early foetal development. We hypothesized that increased levels of the amyloid precursor protein (APP), and particularly its neurotoxic beta-amyloid (1-42) fragment, could disrupt alpha3 gene expression, likely by facilitating premature neuronal differentiation. Indeed, we find increased APP content in the hippocampi of the Down foetuses. In a corresponding cellular model, soluble beta-amyloid (1-42) administered to cultured SH-SY5Y neuroblastoma cells, augmented by retinoic acid-induced differentiation towards a neuronal phenotype, displayed a reduction in alpha3 subunit levels. In sum, this study charts a comprehensive regional and subcellular map of key GABAA receptor subunits in identified neuronal populations in the hippocampus of healthy and Down syndrome foetuses and associates increased beta-amyloid load with discordant down-regulation of alpha3 subunits. PMID- 29168011 TI - Pediatric prolactinoma: initial presentation, treatment, and long-term prognosis. AB - : Prolactinoma is a rare pituitary adenoma secreting prolactin. Studies on diagnostics, treatment, and prognosis in pediatric prolactinoma patients are rare. We analyzed clinical presentation, response to treatment, and prognosis of 27 pediatric prolactinoma patients (10 m/17 f. based on patients' records. Tumors included 6 microadenomas (tumor volume: median 0.2 cm3, range 0.01-0.4 cm3; serum prolactin at diagnosis: median 101 ng/ml, range 33-177 ng/ml), 15 macroadenomas (volume: median 3.3 cm3, range 0.4-25.8 cm3; prolactin: median 890 ng/ml, range 87-8624), and 3 giant adenomas (volume: median 44.5 cm3, range 38.6-93.5 cm3; prolactin: median 4720 ng/ml, range 317-10,400); data for 3 patients were not available. Dopamine agonist treatment (n = 22) was safe and effective, leading to reductions in tumor size (p < 0.01) and prolactin levels (p < 0.01). Threat to vision was the indication for decompressing surgery in three of seven operated patients. No patient was irradiated. Long-term functional capacity was not impaired when compared with other sellar masses (n = 235). CONCLUSION: In pediatric prolactinoma, diagnosis is based on hyperprolactinemia and imaging. Dopamine agonist treatment is effective and safe. Overall survival and functional capacity as a measure of quality of survival were not impaired, indicating an optimistic prognosis. Surgery should be considered only in emergency situations of threatened visual function, not presenting a fast response to dopamine agonist treatment. Severe side effects of medication and lack of efficacy should be considered as contraindications. What is Known: * In pediatric prolactinoma-a very rare pediatric neuroendocrinological disease-gender-related differences in terms of clinical presentation at initial diagnosis are known. * Due to the rareness of the disease, reports on long-term outcome and prognosis after childhood-onset prolactinoma based on prospective follow-up are not published. What is New: * Dopamine agonist treatment is efficient and safe for tumor volume reduction in pediatric prolactinoma and surgical interventions are recommended only for decompression of the optic chiasm in case of threat to vision. In case of inefficient response to medication, side effects or parental refuse, alternative therapeutic options should be considered. * Quality of life in terms of survival and functional capacity was not impaired in pediatric prolactinoma patients when compared with 235 long-term survivors of different sellar masses. PMID- 29168010 TI - Modulation of thalamocortical oscillations by TRIP8b, an auxiliary subunit for HCN channels. AB - Hyperpolarization-activated cyclic nucleotide-gated cation (HCN) channels have important functions in controlling neuronal excitability and generating rhythmic oscillatory activity. The role of tetratricopeptide repeat-containing Rab8b interacting protein (TRIP8b) in regulation of hyperpolarization-activated inward current, I h, in the thalamocortical system and its functional relevance for the physiological thalamocortical oscillations were investigated. A significant decrease in I h current density, in both thalamocortical relay (TC) and cortical pyramidal neurons was found in TRIP8b-deficient mice (TRIP8b-/-). In addition basal cAMP levels in the brain were found to be decreased while the availability of the fast transient A-type K+ current, I A, in TC neurons was increased. These changes were associated with alterations in intrinsic properties and firing patterns of TC neurons, as well as intrathalamic and thalamocortical network oscillations, revealing a significant increase in slow oscillations in the delta frequency range (0.5-4 Hz) during episodes of active-wakefulness. In addition, absence of TRIP8b suppresses the normal desynchronization response of the EEG during the switch from slow-wave sleep to wakefulness. It is concluded that TRIP8b is necessary for the modulation of physiological thalamocortical oscillations due to its direct effect on HCN channel expression in thalamus and cortex and that mechanisms related to reduced cAMP signaling may contribute to the present findings. PMID- 29168012 TI - Cost-effectiveness of rule-based immunoprophylaxis against respiratory syncytial virus infections in preterm infants. AB - : The objective of the paper is to assess the cost-effectiveness of targeted respiratory syncytial virus (RSV) prophylaxis based on a validated prediction rule with 1-year time horizon in moderately preterm infants compared to no prophylaxis. Data on health care consumption were derived from a randomised clinical trial on wheeze reduction following RSV prophylaxis and a large birth cohort study on risk prediction of RSV hospitalisation. We calculated the incremental cost-effectiveness ratio (ICER) of targeted RSV prophylaxis vs. no prophylaxis per quality-adjusted life year (QALYs) using a societal perspective, including medical and parental costs and effects. Costs and health outcomes were modelled in a decision tree analysis with sensitivity analyses. Targeted RSV prophylaxis in infants with a first-year RSV hospitalisation risk of > 10% resulted in a QALY gain of 0.02 (0.931 vs. 0.929) per patient against additional cost of ?472 compared to no prophylaxis (ICER ?214,748/QALY). The ICER falls below a threshold of ?80,000 per QALY when RSV prophylaxis cost would be lowered from ?928 (baseline) to ?406 per unit. At a unit cost of ?97, RSV prophylaxis would be cost saving. CONCLUSIONS: Targeted RSV prophylaxis is not cost-effective in reducing RSV burden of disease in moderately preterm infants, but it can become cost-effective if lower priced biosimilar palivizumab or a vaccine would be available. PMID- 29168013 TI - Clinical features and treatment of pediatric patients with drug-induced anaphylaxis: a study based on pharmacovigilance data. AB - : We assessed the clinical features and treatment of pediatric patients with drug induced anaphylaxis in clinical settings. Pediatric drug-induced anaphylaxis cases collected by the Beijing Pharmacovigilance Database from 2004 to 2014 were analyzed. A total of 91 cases were identified. Drug-induced anaphylaxis was primarily caused by antibiotics (53%). Children of 0-5 years were more likely to develop cyanosis symptoms than children of 13-17 years (OR = 5.14, 95%CI [1.74, 15.20], P = 0.002). Children of 13-17 years were more likely to develop hypotension than children of 6-12 years (OR = 11.79, 95%CI [2.28, 60.87], P = 0.002), and to manifest both neurological symptoms (OR = 3.56, 95%CI [1.26, 10.08], P = 0.015) and severe anaphylaxis than children of 0-5 years (OR = 15.46, 95%CI [1.85, 129.33], P = 0.002). Supratherapeutic doses of epinephrine were more likely with intravenous (IV) bolus (92%) in contrast to either intramuscular (IM) (36%, OR = 19.25, 95%CI [1.77, 209.55], P = 0.009) or subcutaneous (SC) injections (36%, OR = 19.80, 95% CI [1.94, 201.63], P = 0.005). Only 62 (68%) patients received epinephrine treatment as the first-line therapy. CONCLUSION: This study demonstrates that antibiotics were the most common cause of pediatric drug-induced anaphylaxis. Children may present with different anaphylactic signs/symptoms based on age groups. Epinephrine is under-utilized and provider education on the proper management of drug-induced anaphylaxis is warranted. What is Known: * The most common causes of anaphylaxis in children are allergies to foods. Drugs are the second most common cause of pediatric anaphylaxis. * IM epinephrine is the recommended initial treatment of anaphylaxis. What is New: * Drug-induced anaphylaxis in pediatric patients has age-related clinical features. * IV bolus epinephrine was overused and associated with supratherapeutic dosing. PMID- 29168014 TI - Myocardial perfusion reserve quantified by cardiac magnetic resonance imaging is associated with late gadolinium enhancement in hypertrophic cardiomyopathy. AB - Late gadolinium enhancement (LGE) with cardiac magnetic resonance (CMR) imaging has demonstrated the capability of stratifying hypertrophic cardiomyopathy (HCM). Stress perfusion test of CMR can quantify myocardial perfusion reserve (MPR), but its clinical role is not determined. The purpose of this study was to investigate the relationship between MPR and LGE in patients with HCM. A total of 61 consecutive cases underwent complete evaluation with electrocardiography and CMR [cine imaging, coronary MR angiography (MRA), and stress perfusion testing with LGE]. HCM cases were diagnosed by the Japanese conventional guideline prior to this CMR study. Mild LVH was defined as more than 13 mm in maximum LV wall thickness at end diastole on the cine imaging of the CMR. MPR was calculated as the ratio of stress/rest myocardial blood flow using an intensity curve on the stress perfusion test. Cases with ischemic heart disease were excluded from the study based on clinical history and coronary MRA. There were 37 HCM and 24 mild LVH cases (average age: 60.5 +/- 10.9 vs. 64.8 +/- 10.8; male: 62.2 vs. 75.0%, respectively, non-significant). MPR in HCM was lower than in LVH (1.5 +/- 0.5 vs. 2.2 +/- 0.9, p < 0.001) and normal subjects (2.4 +/- 0.9, p < 0.001). MPR in HCM with LGE (N = 34) was lower than in HCM without LGE (N = 3) (1.4 +/- 0.5 vs. 2.1 +/- 0.2, p = 0.014). Multiple regression analysis verified that LGE was the strongest predictor of MPR among multiple clinical parameters, including LVH, LV dysfunction (ejection fraction < 50%), and the presence of negative T wave (p < 0.001). MPR was impaired in HCM with LGE compared with HCM without LGE. The clinical role of MPR on CMR needs to be clarified by further research. PMID- 29168016 TI - Qualitative Evaluation of a Peer Navigator Program for Latinos with Serious Mental Illness. AB - Peer navigator programs (PNP) may help reduce physical health disparities for ethnic minorities with serious mental illness (SMI). However, specific aspects of PNP that are important to peer navigators and their clients are under-researched. A qualitative study explored the perspectives of service users (n = 15) and peer navigators (n = 5) participating in a randomized controlled trial of a PNP for Latinos with SMI. Results show PN engagement with service users spans diverse areas and that interactions with peers, trust, and accessibility are important from a service user perspective. PNs discussed needs for high-quality supervision, organizational support, and additional resources for undocumented Latinos. PMID- 29168015 TI - Ascending aortic blood flow velocity is increased in children with primary snoring/mild sleep-disordered breathing and associated with an increase in CD8 + T cells expressing TNFalpha and IFNgamma. AB - Sleep-disordered breathing (SDB) is associated with cardiovascular disease and systemic inflammation in adults but this remains to be explored in children, especially in children with the most common form of SDB, i.e. primary snoring/mild SDB. This pilot study investigated the relationship between the cardiovascular function and inflammation in children with mild SDB. Nineteen participants aged 5-14 years underwent overnight polysomnography, cardiac magnetic resonance imaging (aortic blood flow velocity and left and right ventricular systolic function) and assessment for inflammatory markers (intracellular cytokine analysis of T cells by flow cytometry). Parents also completed the Sleep Disturbances Scale for Children (SDSC). Children with mild SDB exhibited increased ascending aortic peak systolic velocity compared to controls (SDB 119.95 m/s vs. control 101.49 m/s, p < 0.05). No significant group differences were observed for left and right ventricular ejection fraction or mean aortic blood flow velocity from either the ascending aorta or pulmonary artery. Children with mild SDB had increased inflammatory markers as demonstrated by elevated T cell interferon gamma (IFNgamma) (SDB 52 +/- 4% vs. control 25 +/- 3% positive cells, p < 0.005) and tumour necrosis factor alpha (TNFalpha) (SDB 39 +/- 4% vs. control 20 +/- 2% positive cells, p < 0.005) expression from CD8+ cells. A strong positive correlation was observed between ascending aorta peak blood flow velocity and both TNFalpha and IFNgamma (TNFalpha, r = 0.54, p < 0.03; IFNgamma, r = 0.63, p < 0.005, respectively). Polysomnography revealed that oxygen saturation (SaO2) nadir was significantly lower in children with mild SDB compared to controls (SDB 92.3 +/- 2.7% vs. control 94.4 +/- 1.6%, p < 0.05). A lower SaO2 nadir was associated with an increased ascending aorta peak systolic velocity (r = - 0.48, p < 0.05). As well, both a lower SaO2 nadir and an increased ascending aorta peak systolic velocity were associated with higher SDSC Sleep-Disordered Breathing and Disorder of Initiating and Maintaining Sleep subscale scores but not the polysomnographic-derived Obstructive Apnea-Hypopnea Index. The finding of elevated ascending aortic peak systolic blood flow velocity and its association with increased inflammatory markers suggests that the profile of cardiovascular changes noted in adult SDB may also occur in children with mild SDB. PMID- 29168017 TI - A Comparative Study of the Robustness of Frequency-Domain Connectivity Measures to Finite Data Length. AB - In this work we use numerical simulation to investigate how the temporal length of the data affects the reliability of the estimates of brain connectivity from EEG time-series. We assume that the neural sources follow a stable MultiVariate AutoRegressive model, and consider three connectivity metrics: imaginary part of coherency (IC), generalized partial directed coherence (gPDC) and frequency domain granger causality (fGC). In order to assess the statistical significance of the estimated values, we use the surrogate data test by generating phase randomized and autoregressive surrogate data. We first consider the ideal case where we know the source time courses exactly. Here we show how, expectedly, even exact knowledge of the source time courses is not sufficient to provide reliable estimates of the connectivity when the number of samples gets small; however, while gPDC and fGC tend to provide a larger number of false positives, the IC becomes less sensitive to the presence of connectivity. Then we proceed with more realistic simulations, where the source time courses are estimated using eLORETA, and the EEG signal is affected by biological noise of increasing intensity. Using the ideal case as a reference, we show that the impact of biological noise on IC estimates is qualitatively different from the impact on gPDC and fGC. PMID- 29168018 TI - A Robotic Flexible Drill and Its Navigation System for Total Hip Arthroplasty. AB - This paper presents a robotic flexible drill and its navigation system for total hip arthroplasty (THA). The new robotic system provides an unprecedented and unique capability to perform curved femoral milling under the guidance of a multimodality navigation system. The robotic system consists of three components. Firstly, a flexible drill manipulator comprises multiple rigid segments that act as a sheath to a flexible shaft with a drill/burr attached to the end. The second part of the robotic system is a hybrid tracking system that consists of an optical tracking system and a position tracking system. Optical tracking units are used to track the surgical objects and tools outside the drilling area, while a rotary encoder placed at each joint of the sheath is synchronized to provide the position information for the flexible manipulator with its virtual object. Finally, the flexible drill is integrated into a computer-aided navigation system. The navigation system provides real time guidance to a surgeon during the procedure. The flexible drill system is then able to implement THA by bone milling. The final section of this paper is an evaluation of the flexible and steerable drill and its navigation system for femoral bone milling in sawbones. PMID- 29168019 TI - The operations of the free maternal care policy and out of pocket payments during childbirth in rural Northern Ghana. AB - BACKGROUND: To promote skilled attendance at births and reduce maternal deaths, the government of Ghana introduced the free maternal care policy under the National Health Insurance Scheme (NHIS) in 2008. The objective is to eliminate financial barriers associated with the use of services. But studies elsewhere showed that out of pocket (OOP) payments still exist in the midst of fee exemptions. The aim of this study was to estimate OOP payments and the financial impact on women during childbirth in one rural and poor area of Northern Ghana; the Kassena-Nankana municipality. Costs were taken from the perspective of women. METHODS: Quantitative and qualitative data collection techniques were used in a convergent parallel mixed methods study. The study used structured questionnaire (n = 353) and focus group discussions (FGDs =7) to collect data from women who gave birth in health facilities. Quantitative data from the questionnaire were analysed, using descriptive statistics. Qualitative data from the FGDs were recorded, transcribed and analysed to determine common themes. RESULTS: The overall mean OOP payments during childbirth was GHc33.50 (US$17), constituting 5.6% of the average monthly household income. Over one-third (36%, n = 145) of women incurred OOP payments which exceeded 10% of average monthly household income (potentially catastrophic). Sixty-nine percent (n = 245) of the women perceived that the NHIS did not cover all expenses incurred during childbirth; which was confirmed in the FGDs. Both survey and FGDs demonstrated that women made OOP payments for drugs and other supplies. The FGDs showed women bought disinfectants, soaps, rubber pads and clothing for newborns as well. Seventy-five percent (n = 264) of the women used savings, but 19% had to sell assets to finance the payments; this was supported in the FGDs. CONCLUSION: The NHIS policy has not eliminated financial barriers associated with childbirth which impacts the welfare of some women. Women continued to make OOP payments, largely as a result of a delay in reimbursement by the NHIS. There is need to re-examine the reimbursement system in order to prevent shortage of funding to health facilities and thus encourage skilled attendance for the reduction of maternal deaths as well as the achievement of universal health coverage. PMID- 29168020 TI - Copper chaperone antioxidant-1, Atox-1, is involved in the induction of SOD3 in THP-1 cells. AB - Superoxide dismutase (SOD) 3, a copper (Cu)-containing anti-oxidative enzyme, plays a key role in extracellular redox homeostasis. Cu chaperone antioxidant-1 (Atox-1) not only delivers Cu ions to SOD3 at the trans-Golgi network, it also functions as a transcription factor of SOD3; however, the role of Atox-1 in the regulation of SOD3 during the monocytic differentiation of THP-1 cells has not yet been elucidated. A treatment with 12-O-tetradecanoylphorbol-13-acetate (TPA) induced the expression of the Cu transport protein ATP7A in THP-1 cells. On the other hand, the nuclear translocation of Atox-1 was detected in TPA-treated THP-1 cells, and was suppressed in the presence of the Cu chelator, bathocuproinedisulfonic acid. Furthermore, Atox-1 bound to the SOD3 promoter region in TPA-treated THP-1 cells. The overexpression of Atox-1 in THP-1 cells significantly enhanced TPA-elicited SOD3 expression, whereas its knockdown suppressed this induction. The present results demonstrate that Atox-1 functions as a key molecule in TPA-elicited SOD3 expression.

AB - NMR spectroscopy of membrane proteins involved in electron transport is difficult due to the presence of both the lipids and paramagnetic centers. Here we report the solution NMR study of the NADPH-cytochrome P450 oxidoreductase (POR) in its reduced and oxidized states. We interrogate POR, first, in its truncated soluble form (70 kDa), which is followed by experiments with the full-length protein incorporated in a lipid nanodisc (240 kDa). To overcome paramagnetic relaxation in the reduced state of POR as well as the signal broadening due to its high molecular weight, we utilized the methyl-TROSY approach. Extrinsic 13C-methyl groups were introduced by modifying the engineered surface-exposed cysteines with methyl-methanethiosulfonate. Chemical shift dispersion of the resonances from different sites in POR was sufficient to monitor differential effects of the reduction-oxidation process and conformation changes in the POR structure related to its function. Despite the high molecular weight of the POR-nanodisc complex, the surface-localized 13C-methyl probes were sufficiently mobile to allow for signal detection at 600 MHz without perdeuteration. This work demonstrates a potential of the solution methyl-TROSY in analysis of structure, dynamics, and function of POR, which may also be applicable to similar paramagnetic and flexible membrane proteins. PMID- 29168022 TI - No advantage of fresh blastocyst versus cleavage stage embryo transfer in women under the age of 39: a randomized controlled study. AB - PURPOSE: Is there a difference in implantation and pregnancy rates between embryos transferred electively at cleavage or blastocyst stage in infertile women <= 38 years with at least four zygotes on day 1 post retrieval? METHODS: A randomized clinical trial was conducted in a single tertiary care hospital with a sample size of 194 patients in each arm for a total population of 388 women. Patients less than 39 years of age with more than three fertilized oocytes and less than four previous assisted reproductive technology (ART) attempts were inclusion criteria. RESULTS: The two groups were similar for age, years of infertility, indication to treatment, basal antimullerian hormone and FSH, number of previous ART cycles, primary or secondary infertility, type of induction protocol, days of stimulation, total gonadotrophin dose, and estradiol (E2) and progesterone (P) levels at trigger. No statistically significant differences were found in terms of number of retrieved oocytes, inseminated oocytes, fertilization rate, canceled transfers (7.73% in blastocyst and 3.61% in cleavage stage group), and cycles with frozen embryos and/or oocytes. Although a higher number of fertilized oocytes were in the blastocyst stage group (6.18 +/- 1.46 vs 5.89 +/- 1.54, p = 0.052), a statistically greater number of embryos/randomized cycle were transferred at cleavage stage (1.93 +/- 0.371) compared with the number of transferred blastocysts (1.80 +/- 0.56), probably due to the number of embryos not reaching blastocyst stage (3.09%). The implantation rate (28.37 vs 25.67%), pregnancy rate per cycle (36.06 vs38.66%), transfer (39.66 vs 40.11%), spontaneous abortions (19.72% vs 12.00%), delivery rate per cycle (27.84 vs 32.99%), and transfer (30.17 vs 34.22%) were not significantly different between the blastocyst and cleavage stage groups. The twin delivery rate was higher in the blastocyst stage group, although not significant (42.59 vs 28.12%). The mean numbers of frozen blastocyst (2.30 +/- 1.40 vs 2.02 +/- 1.00) and frozen oocytes (7.09 +/- 3.55vs 6.79 +/- 3.26) were not significantly different between the two groups. CONCLUSIONS: Fresh blastocyst-stage transfer versus cleavage-stage transfer did not show any significant difference in terms of implantation and pregnancy rate in this selected group of patients. A high twin delivery rate in both groups (35.59%) was registered, and although not significant, they were higher in the blastocyst transfer group (42.59 vs 28.12%). Our conclusion supports considering single embryo transfer (SET) policy, even in cleavage stage in patients younger than 39 years with at least four zygotes. TRIAL REGISTRATION: ClinicalTrials.gov registration number NCT02639000. PMID- 29168023 TI - Oxytocin and parenting behavior among impoverished mothers with low vs. high early life stress. AB - Recent work suggests that key aspects of sensitive parenting (e.g., warmth, emotional attunement) may be shaped in part by biology, specifically the neuropeptide oxytocin. However, some studies have found that oxytocin may not act in expected ways in higher-risk populations (e.g., those with postnatal depression or borderline personality disorder). This study examined the relation between oxytocin and parenting among mothers with varying levels of early life stress. Forty low-income mothers and their 34- to 48-month-old child participated in this study. Mother-child dyads were observed in an interaction task in their home, and videos of these interactions were later coded for parenting behaviors. Mothers' oxytocin production before and after the interaction task was assessed through saliva. Mothers' early stress was assessed via the Adverse Childhood Experiences Scale (ACES; Felitti et al. Am J Prev Med 14:245-258, 1998). For mothers with low ACEs, higher oxytocin secretion was associated with more positive parenting. For mothers with high ACEs, higher oxytocin secretion was associated with lower levels of positive parenting. Oxytocin may be operating differently for mothers who experienced harsh early social environments, supporting more defensive behaviors and harsh parenting than anxiolytic and prosocial behaviors. PMID- 29168024 TI - Teenage pregnancy and long-term mental health outcomes among Indigenous women in Canada. AB - Our objectives were to (1) compare the risks for poor long-term mental health outcomes among indigenous women with and without a teenage pregnancy and (2) determine if community and cultural factors modify this risk. We conducted a secondary analysis of the 2012 Aboriginal Peoples Survey. Respondents were women aged 25 to 49 years who had given birth to at least one child. Teenage mothers (age at first birth 13 to 19 years; n = 1330) were compared to adult mothers (age at first birth 20 years or older; n = 2630). Mental health outcomes were psychological distress, mental health status, suicide ideation/attempt, and alcohol consumption. To address objective 1, we used binary logistic regression analyses before and after controlling for covariates. To address objective 2, we tested the significance of interaction terms between teenage pregnancy status and effect measure modifiers. In unadjusted analyses, teenage pregnancy was associated with increased risk for poor/fair mental health [odds ratio (OR) 1.77, 95% confidence interval (CI) 1.24-2.53] and suicide attempt/ideation (OR 1.95, 95% CI 1.07-3.54). However, the associations were not statistically significant after adjusting for demographic, socioeconomic, environmental, and health covariates. Teenage pregnancy was not associated with increased risk for high psychological distress or heavy alcohol consumption in unadjusted or adjusted analyses. The interaction term for involvement in cultural activities was statistically significant for poor/fair mental health; however, after stratification, ORs were non-significant. Among indigenous mothers, teenage pregnancy was less important than broader social and health circumstances in predicting long-term mental health. PMID- 29168025 TI - Relationship between the severity of laryngopharyngeal reflux and sleep apnea: using drug-induced sleep endoscopy (DISE). AB - OBJECTIVES: The aim of the study is to identify the following associations: (1) severity of obstructive sleep apnea syndrome (OSAS) and laryngopharyngeal reflux (LPR)-related clinical parameters, such as reflux finding score (RFS), reflux symptom index (RSI), and LPR-health-related quality of life (LPR-HRQOL) and (2) complete obstruction on drug-induced sleep endoscopy (DISE) and LPR-related clinical parameters. MATERIALS AND METHODS: Subjects included the OSAS patients without surgery history and all patients perform the polysomnography (PSG) and DISE for their OSAS. Demographics, polysomnographic data, DISE results, and LPR related parameters were collected prospectively. The patients were divided into age-, sex-, and BMI-matched two groups, according to numbers of complete obstruction on DISE (complete obstruction at 0-1 subsites (unilevel) vs. 2-4 subsites (multilevel). Finally, 19 patients with unilevel complete obstruction and 38 patients with multilevel complete obstruction were compared. The multiple linear regression analysis was employed to determine the predictors of LPR related quality of life. RESULTS: Among 88 patients, 19 patients demonstrated unilevel complete obstruction, and 69 patients demonstrated multilevel complete obstruction on DISE. There were no significant correlation between OSAS severity and RFS, RSI, and scores of LPR-HRQOL. Multilevel complete obstruction on DISE did not affect the LPR-related clinical parameters (p > 0.05). The result of multiple linear regression demonstrated complete obstruction at the epiglottis had a strong influence on the high scores of LPR-HRQOL. CONCLUSION: LPR is commonly developing disease with OSAS, but the OSAS severity did not affect the LPR-related parameters. The multilevel complete obstruction on DISE was not associated with the LPR-related clinical parameters. PMID- 29168026 TI - Author's reply to "Letter to the editor on the article: Saccular measurements in routine MRI can predict hydrops in Meniere's disease by Simon F et al." AB - This is an answer to the Letter to the Editor regarding our previously published article " Saccular measurements in routine MRI can predict hydrops in Meniere's disease ". We thank the authors for their interest in our article and their insightful comments. We would like to emphasise that our article was a preliminary study and to our knowledge the first published series establishing a correlation between measurements of saccular morphology in T2-weighed 3D CISS images and clinical definite Meniere's disease. Therefore, we agree with the authors of the Letter that verifying reproducibility is paramount for the technique to be widely used. Further studies should be conducted to investigate the risk of artefacts reducing the reliability of saccular width measurements and to confirm the clinical implications. We recommend the use of saccular height measurements which have higher reliability. Also, the goal of the study was to present a possible radiological alternative to the more established methods of endolymphatic hydrops visualisation. If accessible, we agree that the latter techniques should be preferred, but we find that they are unfortunately too often unavailable in routine clinical practice to ENT physicians.

A prospective randomized multicenter trial. AB - PURPOSE: The purpose of this prospective, randomized, multicenter clinical trial was to compare the therapeutic efficacy of systemic versus intratympanic versus combined administration of steroids in the treatment of idiopathic sudden sensorineural hearing loss. METHODS: 102 patients with an up to 14 days history of idiopathic sudden sensorineural hearing loss were randomized to 1 of 3 arms and followed prospectively. Group A (35 patients) received prednisolone intravenously followed by methylprednisolone orally, whereas Group B (34 patients) were administered intratympanic methylprednisolone. Patients in Group C (33 patients) were administered the combination of the above-mentioned treatment modalities. The patients were followed-up with pure tone audiograms on days 1 (initiation of treatment), 3, 5, 10, 30 and 90. RESULTS: The final mean hearing gain was 29.0 dB HL for Group A, 27.0 dB HL for Group B and 29.8 dB HL for Group C. The differences between the three groups were not statistically significant. When hearing improvement was assessed according to Siegel's criteria, no statistically significant difference was recorded either. Furthermore, patients younger than 60 years old achieved significantly better hearing outcomes. CONCLUSIONS: The results demonstrated that systemic, intratympanic and combined steroid administration have similar results in the primary treatment of idiopathic sudden hearing loss. Younger patients are more likely to achieve better hearing outcomes. PMID- 29168030 TI - The Assessment of Competency in Thoracic Sonography (ACTS) scale: validation of a tool for point-of-care ultrasound. AB - BACKGROUND: The rapid adoption of point-of-care ultrasound (POCUS) has created a need to develop assessment tools to ensure that learners can competently use these technologies. In this study, the authors developed and tested a rating scale to assess the quality of point-of-care thoracic ultrasound studies performed by novices. In Phase 1, the Assessment of Competency in Thoracic Sonography (ACTS) scale was developed based on structured interviews with subject matter experts. The tool was then piloted on a small series of ultrasound studies in Phase 2. In Phase 3 the tool was applied to a sample of 150 POCUS studies performed by ten learners; performance was then assessed by two independent raters. RESULTS: Evidence for the content validity of the ACTS scale was provided by a consensus exercise wherein experts agreed on the general principles and specific items that make up the scale. The tool demonstrated reasonable inter rater reliability despite minimal requirements for evaluator training and displayed evidence of good internal structure, with related scale items correlating well with each other. Analysis of the aggregate learning curves suggested a rapid early improvement in learner performance with slower improvement after approximately 25-30 studies. CONCLUSIONS: The ACTS scale provides a straightforward means to assess learner performance. Our results support the conclusion that the tool is an effective means of making valid judgments regarding competency in point-of-care thoracic ultrasound, and that the majority of learner improvement occurs during their first 25-30 practice studies. PMID- 29168029 TI - The Chinese version of the SLEQOL is a reliable assessment of health-related quality of life in Han Chinese patients with systemic lupus erythematosus. AB - To assess the health-related quality of life (HRQOL) of Han Chinese people with systemic lupus erythematosus (SLE) using a Chinese version of the Systemic Lupus Erythematosus-Specific Quality of Life Questionnaire (SLEQOL-C) and explore the factors influencing HRQOL of people with SLE. Participants were Han Chinese people with SLE. The SLEQOL-C and 36-item Short Form Health Survey (SF-36) were used to estimate the HRQOL. Disease activity was determined using the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and fatigue using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). Participant factors included age, gender, educational background, disease duration, erythrocyte sedimentation rate (ESR), and complement C3 and C4 levels. The results showed that higher SLEQQL-C scores correlated with lower SF-36 both measures are essential for HRQQL prediction. The SLEQOL-C scores were correlated with educational level,age, FACIT-F score, SLEDAI score, and ESR, which suggests that poor educational background, old-age, and increased fatigue, disease activity, and ESR might represent poor HRQOL. Although disease duration did not significantly correlate with the scores on the SLEQOL-C; those whose disease duration was 12-24 months had higher SLEQOL-C summary scores and physical functioning, symptoms, and treatment subscale scores than did those whose duration was less than 6 months. The FACIT-F score, education level, age, disease duration, SLEDAI score, and ESR contributed to SLEQOL-C scores. The SLEQOL-C is reliable for assessing HRQOL of Han Chinese people with SLE. Fatigue, educational level, age, disease duration, ESR, and disease activity mainly influenced HRQOL of SLE patients. PMID- 29168031 TI - Neural cells generated from human induced pluripotent stem cells as a model of CNS involvement in mucopolysaccharidosis type II. AB - Mucopolysaccharidosis type II (MPSII) is a rare X-linked lysosomal storage disorder caused by mutations in the iduronate-2-sulfatase (IDS) gene (IDS, Xq28). MPSII is characterized by skeletal deformities, hearing loss, airway obstruction, hepatosplenomegaly, cardiac valvular disease, and progressive neurological impairment. At the cellular level, IDS deficiency leads to lysosomal storage of glycosaminoglycans (GAGs), dominated by accumulation of dermatan and heparan sulfates. Human induced pluripotent stem cells (iPSC) represent an alternative system that complements the available MPSII murine model. Herein we report on the reprogramming of peripheral white blood cells from male and female MPSII patients into iPSC using a non-integrating protocol based on the Sendai virus vector system. We differentiated the iPSC lines into IDS deficient and GAG accumulating beta-Tubulin III+ neurons, GFAP+ astrocytes, and CNPase+ oligodendrocytes. The lysosomal system in these cells displayed structural abnormalities reminiscent of those previously found in patient tissues and murine IDS deficient neuronal stem cells. Furthermore, quantitative determination of GAGs revealed a moderate increase in GAG levels in IDS deficient neurons and glia. We also tested the effects of recombinant IDS and found that the exogenous enzyme was internalized from the culture media and partially decreased the intracellular GAG levels in iPSC-derived neural cells; however, it failed to completely prevent accumulation of GAGs. In summary, we demonstrate that this human iPSC based model expresses the cellular and biochemical features of MPSII, and thus represents a useful experimental tool for further pathogenesis studies as well as therapy development and testing. PMID- 29168032 TI - Comparison of the MASCC and CISNE scores for identifying low-risk neutropenic fever patients: analysis of data from three emergency departments of cancer centers in three continents. AB - PURPOSE: Patients with febrile neutropenia are a heterogeneous group with a minority developing serious medical complications. Outpatient management of low risk febrile neutropenia has been shown to be safe and cost-effective. Scoring systems, such as the Multinational Association for Supportive Care in Cancer (MASCC) score and Clinical Index of Stable Febrile Neutropenia (CISNE), have been developed and validated to identify low-risk patients. We aimed to compare the performance of these two scores in identifying low-risk febrile neutropenic patients. METHODS: We performed a pooled analysis of patients presenting with febrile neutropenia to three tertiary cancer emergency centers in the USA, UK, and South Korea in 2015. The primary outcome measures were the occurrence of serious complications. Admission to an intensive care unit (ICU) and 30-day mortality were secondary outcomes. The predictive performance of each score was analyzed. RESULTS: Five hundred seventy-one patients presented with febrile neutropenia. With MASCC risk index, 508 (89.1%) were classified as low-risk febrile neutropenia, compared to 60 (10.5%) with CISNE classification. Overall, the MASCC score had a greater discriminatory power in the detection of low-risk patients than the CISNE score (AUC 0.772, 95% CI 0.726-0.819 vs. 0.681, 95% CI 0.626-0.737, p = 0.0024). CONCLUSION: Both MASCC and CISNE scores have reasonable discriminatory value in predicting patients with low-risk febrile neutropenia. Risk scores should be used in conjunction with clinical judgment for the identification of patients suitable for outpatient management of neutropenic fever. Developing more accurate scores, validated in prospective settings, will be useful in facilitating more patients being managed in an outpatient setting. PMID- 29168033 TI - A prospective, multicenter pilot study to investigate the feasibility and safety of a 1-year controlled exercise training after adjuvant chemotherapy in colorectal cancer patients. AB - INTRODUCTION: Despite advances in adjuvant chemotherapy, 20-30% of patients in stages II-III colorectal cancer will eventually relapse. Observational studies showed a reduction in relapse rate, colon cancer-specific mortality, and overall mortality by physical activity. Results from prospective randomized interventional studies to confirm these observational data are lacking. The aims of this prospective single-arm multicenter pilot study are to evaluate feasibility and safety of exercise training after adjuvant chemotherapy in colorectal cancer patients. PATIENTS AND METHODS: The training was performed three times per week for 1 year and was increased gradually in three phases until reaching 18 metabolic equivalent task hours per week. RESULTS: Overall, 30 patients were included. The planned training intensity could be achieved in all three phases. Patients experienced a performance increase of median 35.5 watt, a weight-loss of a median of 3.0 kg, and a reduction in body fat content of median 1.0% during this exercise training. The analysis showed early study termination due to non-compliance in 10/30 patients (33.3%), disease progression in 4 patients (13.3%), and serious adverse events in 2 patients (6.7%). About half of patients (46.7%) completed the pilot study as planned. Biomarker analysis from 20 patients showed a non-significant reduction in insulin-like growth factor 1 (IGF 1), insulin-like growth factor 2 (IGF-2) and insulin-like growth factor binding protein 3 (IGF-BP3) levels, significant increases in adiponectin and leptin levels, and a non-significant increase in C-peptide levels. CONCLUSION: Exercise training is feasible in patients with colorectal cancer after completion of adjuvant chemotherapy. The main problem encountered during the study was compliance. To improve compliance of exercise training, several measures were adapted for the upcoming prospective randomized ABCSG C08 Exercise II study. PMID- 29168034 TI - Physical activity among cancer survivors-what is their perception and experience? AB - PURPOSE: Physical activity (PA) plays an important role relating to cancer. The aim of this study was to investigate the attitude to and experience with the subject of PA in cancer in a large group of tumour patients. METHODS: A standardised questionnaire was carried out and distributed to patients online and in printed form. RESULTS: Nine hundred five patients answered the questionnaire. Most tumour patients (60%) received information about PA after their cancer therapy. The Internet was often rated to be inadequate as a source of information. One in two tumour patients were recommended PA by a therapist. During the acute phase, the majority (57% of the 776) did not receive a sport therapeutic exercise programme. Two thirds (68%) of the 898 patients indicated regularly engaging in PA at least 3 or 5 days per week. In most cases (30% of the 787), 2 to 4 h per week were dedicated to PA. In addition to a desire to increase well-being, enjoyment played a large role. Weakness and lack of willpower are among the most common barriers. Most tumour patients confirmed that PA improved their body awareness (58%) or gave them the feeling that they could do something to better cope with the disease (61%) or feel better (68%). CONCLUSION: On the one hand, the information requirements of tumour patients with respect to PA have not been adequately taken into account by practitioners. On the other hand, there are still subjective inhibitions on the part of the patients, which keep them from engaging in PA. PMID- 29168035 TI - Prevalence and correlates of high fear of cancer recurrence in late adolescents and young adults consulting a specialist adolescent and young adult (AYA) cancer service. AB - OBJECTIVE: High fear of cancer recurrence (FCR) is a frequently reported problem among cancer patients. Previous research has shown that younger age is associated with higher levels of FCR. However, little attention has been given to date about how FCR manifests itself among adolescent and young adult (AYA) cancer patients. This study explores the prevalence, correlates of high FCR, and its association with HRQoL in cancer patients in their late adolescence or young adulthood. METHODS: Seventy-three AYA cancer patients, aged 18-35 years at diagnosis, consulted the AYA team of the Radboud University Medical Center completed questionnaires including the Cancer Worry Scale (CWS), Quality of Life-Cancer Survivors (QOL-CS), and Hospital Anxiety and Depression Scale (HADS). Sociodemographic and medical data was collected by self-reported questionnaire. RESULTS: Forty-five participants experienced high FCR (62%), which was higher than the 31-52% reported in previous studies among mixed adult cancer patient samples. Sociodemographic and medical variables were not associated with levels of FCR. High FCR was significantly associated with lower levels of social and psychological functioning and overall HRQoL and higher levels of anxiety and psychological distress. CONCLUSION: Results illustrate that FCR is a significant problem among AYA cancer patients consulting an AYA team, with participants reporting higher levels of FCR than cancer patients of mixed ages. Health care providers should pay specific attention to this problem by screening and the provision of appropriate psychosocial care when needed. PMID- 29168036 TI - The gut microbiome, symptoms, and targeted interventions in children with cancer: a systematic review. AB - PURPOSE: The gut microbiome plays a critical role in maintaining children's health and in preventing and treating children's disease. Current application of the gut microbiome in childhood cancer is still lacking. This study aimed to systematically review the following: (1) alternations in the gut microbiome throughout cancer treatment trajectories in children, (2) the associations between the gut microbiome and gastrointestinal (GI) symptoms and psychoneurological symptoms (PNS), and (3) the efficacy of therapeutic interventions in the gut microbiome in children with cancer. METHODS: PubMed, EMBASE, the Cochrane Library, and the American Society of Clinical Oncology abstract were searched. Eligible studies included all study types in which the gut microbiome was primarily reported in children with cancer. The Mixed Methods Assessment Tool was used to evaluate the methodology quality of included studies. Seven studies met our eligibility criteria, including two cohort studies, two case-control studies, and three randomized controlled trails. RESULTS: The findings showed that the diversity estimates of the gut microbiome in children with cancer were lower than those of healthy controls both pre- and post treatment. Children with cancer showed a significantly lower relative abundance of healthy gut microbiome (e.g., Clostridium XIVa and Bifidobacterium) during and after cancer treatment. No adequate literature was identified to support the associations between dysbiosis of the gut microbiome and GI symptoms/PNS. The use of prebiotics (fructooligosaccharides) and probiotics (Bifidobacterium or Lactobacilli) appears to improve the microenvironment of the gut around 1 month (4-5 weeks) during chemotherapy rather than at the beginning of treatment. Data also suggest that both prebiotic and probiotic interventions decrease clinical side effects (e.g., infection and morbidity risk) in children with cancer. CONCLUSIONS: This study adds to the evidence that dysbiosis of the gut microbiome can be improved using prebiotic and probiotic supplementations in children with cancer. More well-designed experimental studies are needed to confirm this conclusion. Further studies are needed to examine the associations between the gut microbiome and GI symptoms/PNS in childhood cancer. PMID- 29168037 TI - Efficacy and safety of reinfusion of concentrated ascitic fluid for malignant ascites: a concept-proof study. AB - PURPOSE: Malignant ascites is one of the symptoms causing discomfort in advanced cancer patients. Cell-free and concentrated ascites reinfusion therapy (CART) is one treatment modality, but controlled trials are limited. The primary aim of this study was to explore the efficacy and safety of CART, as well as their predictors, to obtain data for planning a further controlled trial. METHODS: This was a single center retrospective cohort study in patients with refractory malignant ascites. Consecutive adult patients who underwent CART were enrolled. The primary endpoints were the time to next paracentesis and seven patient reported symptoms (e.g., abdominal pain and distension). The secondary endpoints were adverse events, laboratory findings, and physical findings. RESULTS: A total of 104 CART procedures for 51 patients were analyzed. The median time to next paracentesis was 27 days (95% CI, 21-35). Intensities of all seven symptoms were significantly improved after CART (p < 0.0001 for all symptoms). Grade 3 hypotension occurred during one procedure, and mild fever occurred in 5%. Total protein, albumin, and estimated glomerular filtration rate were significantly increased. Hemorrhagic ascites, ascites white blood cell count, serum total protein, and lymphocyte percentages were the independent predictors of the time to next paracentesis. CONCLUSION: The effects of reinfusion of concentrated ascitic fluid may be maintained for 1 month, being potentially longer than that of total paracentesis alone. This study had no comparison groups and examined the short-term effect. A randomized controlled study to compare the long-term effects of total paracentesis alone vs. CART is necessary. PMID- 29168038 TI - Ovarian serous carcinomas acquire cisplatin resistance and increased invasion through downregulation of the high-temperature-required protein A2 (HtrA2), following repeated treatment with cisplatin. AB - High-temperature-required protein A2 (HtrA2) is one of the serine proteases related to apoptosis. HtrA2 protein expression has been associated with cisplatin resistance and poor prognosis in ovarian serous adenocarcinoma (SAC). The aim of this study was to understand the influence of HtrA2 on repeated treatment with cisplatin. The change in HtrA2 expression in 31 ovarian cancers was investigated by immunohistochemical analysis, before and after cisplatin-based chemotherapy, and the association between HtrA2 expression after chemotherapy and prognosis was analyzed. The association between the change in HtrA2 and proteins associated with LATS1 in ovarian serous cancer cell lines after repeated treatment with cisplatin was evaluated in vitro. In immunohistochemical analysis, repeated cisplatin treatment induced downregulation of HtrA2 protein expression, before and after cisplatin-based chemotherapy in SAC. Progression-free survival and overall survival of SAC with low expression of HtrA2 were worse than those with high expression. In vitro analysis using cisplatin-sensitive ovarian cancer cell lines, KF28, and cisplatin-resistant cancer cell lines, KFr13, obtained from KF28 by repeated cisplatin treatment, showed that HtrA2 protein expression was lower in KFr13 than in KF28. Furthermore, KFr13 had a higher invasive capacity than KF28. Next, downregulation of HtrA2 transfected with an HtrA2-specific siRNA in KF28 had not only cisplatin resistance, but also more invasive capacity than those with non-specific siRNA. Repeated treatment with cisplatin downregulated the HtrA2 protein, which led to cisplatin resistance and increased invasive capacity. Thus, HtrA2 might be a biomarker of response to cisplatin treatment and prognosis, after cisplatin-based chemotherapy. PMID- 29168039 TI - Sequential Detection of Compromised Items Using Response Times in Computerized Adaptive Testing. AB - Item compromise persists in undermining the integrity of testing, even secure administrations of computerized adaptive testing (CAT) with sophisticated item exposure controls. In ongoing efforts to tackle this perennial security issue in CAT, a couple of recent studies investigated sequential procedures for detecting compromised items, in which a significant increase in the proportion of correct responses for each item in the pool is monitored in real time using moving averages. In addition to actual responses, response times are valuable information with tremendous potential to reveal items that may have been leaked. Specifically, examinees that have preknowledge of an item would likely respond more quickly to it than those who do not. Therefore, the current study proposes several augmented methods for the detection of compromised items, all involving simultaneous monitoring of changes in both the proportion correct and average response time for every item using various moving average strategies. Simulation results with an operational item pool indicate that, compared to the analysis of responses alone, utilizing response times can afford marked improvements in detection power with fewer false positives. PMID- 29168040 TI - The utility of home sleep apnea tests in patients with low versus high pre-test probability for moderate to severe OSA. AB - PURPOSE: Home sleep apnea tests (HSATs) are an alternative to attended polysomnograms (PSGs) when the pre-test probability for moderate to severe OSA is high. However, insurers often mandate use anytime OSA is suspected regardless of the pre-test probability. Our objective was to determine the ability of HSATs to rule in OSA when the pre-test probability of an apnea hypopnea index (AHI) in the moderate to severe range is low. METHODS: Patients who underwent HSATs were characterized as low or high pre-test probability based on the presence of two symptoms of the STOP instrument plus either BMI > 35 or male gender. The odds of HSAT diagnostic for OSA dependent on pre-test probability was calculated. Stepwise selection determined predictors of non-diagnostic HSAT. As PSG is performed after HSATs that do not confirm OSA, false negative results were assessed. RESULTS: Among 196 individuals, pre-test probability was low in 74 (38%) and high in 122 (62%). A lower percentage of individuals with a low versus high pre-test probability for moderate to severe OSA had HSAT results that confirmed OSA (61 versus 84%, p = 0.0002) resulting in an odds ratio (OR) of 0.29 for confirmatory HSAT in the low pre-test probability group (95% CI [0.146, 0.563]). Multivariate logistic regression demonstrated that age <= 50 (OR 3.10 [1.24-7.73]), female gender (OR 3.58[1.50-8.66]), non-enlarged neck circumference (OR 11.50 [2.50-52.93]), and the absence of loud snoring (OR 3.47 [1.30-9.25]) best predicted non-diagnostic HSAT. OSA was diagnosed by PSG in 54% of individuals with negative HSAT which was similar in both pre-test probability groups. CONCLUSION: HSATs should be reserved for individuals with high pre-test probability for moderate to severe disease as opposed to any individual with suspected OSA. PMID- 29168041 TI - Making Sense of SNPs: Women's Understanding and Experiences of Receiving a Personalized Profile of Their Breast Cancer Risks. AB - Genome wide association studies have identified a number of common genetic variants - single nucleotide polymorphisms (SNPs) - that combine to increase breast cancer risk. SNP profiling may enhance the accuracy of risk assessment and provides a personalized risk estimate. SNP testing for breast cancer risks may supplement other genetic tests in the future, however, before it can be implemented in the clinic we need to know how it will be perceived and received. Semi-structured qualitative interviews were conducted with 39 women who had previously had a breast cancer diagnosis and undergone BRCA1/2 testing, participated in the Variants in Practice (ViP) study and received personalized risk (SNP) profiles. Interviews explored their understanding and experiences of receiving this SNP information. Women reported feeling positive about receiving their personalized risk profile, because it: provided an explanation for their previous diagnosis of cancer, vindicated previous risk management decisions and clarified their own and other family members' risks. A small group was initially shocked to learn of the increased risk of a second primary breast cancer. This study suggests that the provision of personalized risk information about breast cancer generated by SNP profiling is understood and well received. However, a model of genetic counseling that incorporates monogenic and polygenic genetic information will need to be developed prior to clinical implementation. PMID- 29168042 TI - Impact of Receiving Secondary Results from Genomic Research: A 12-Month Longitudinal Study. AB - The impact of returning secondary results from exome sequencing (ES) on patients/participants is important to understand as ES is increasingly utilized in clinical care and research. Participants were recruited from studies using ES and were separated into two arms: 107 who had ES and were offered the choice to learn secondary results (ES group) and 85 who had not yet had ES (No ES group). Questionnaires were administered at baseline and 1 and 12 months, following results disclosure (ES group) or enrollment (No ES group). While the majority (65%) elected to learn all results following pre-test counseling, it was reduced from the 76% who indicated a desire for all results at baseline. Thirty-seven percent received results associated with an increased personal disease risk. There were no differences in changes in any of the psychological and social measures from baseline to post-results disclosure between the ES and No ES groups. Receiving a wide range of secondary findings appeared to have little measurable impact on most participants. The experience of learning secondary results may be related to participants' previous experiences with genetics, as well as the genetic counseling provided. Future research with a more diverse, genetically naive group, as well as scalable methods of delivery, is needed. PMID- 29168043 TI - Role of CYP1B1, p.E229K and p.R368H mutations among 120 families with sporadic juvenile onset open-angle glaucoma. AB - BACKGROUND: To determine the frequency of CYP1B1 p.E229K and p.R368H, gene mutations in a cohort of sporadic juvenile onset open-angle glaucoma (JOAG) patients and to evaluate their genotype/phenotype correlation. METHODS: Unrelated JOAG patients whose first-degree relatives had been examined and found to be unaffected were included in the study. The patients and their parents were screened for p.E229K and p.R368H mutations. The phenotypic characteristics were compared between probands carrying the mutations and those who did not carry these mutations. RESULTS: Out of 120 JOAG patients included in the study, the p.E229K mutation was seen in 9 probands (7.5%) and p.R368H in 7 (5.8%). The average age of onset of the disease (p = 0.3) and the highest untreated IOP (p = 0.4) among those carrying mutations was not significantly different from those who did not have these mutations. The proportion of probands with angle dysgenesis among those with p.E229K and p.R368H mutations was 70% (11 out of 16) in comparison to 65% (67 out of 104) of those who did not harbour these mutations (p = 0.56). Similarly, the probands with moderate to high myopia among those with p.E229K and p.R368H mutations was 20% (3 out of 16) in comparison to 18% (18 out of 104) of those who did not harbour these mutations (p = 0.59). CONCLUSION: The frequency of p.E229K and p.R368H mutations of the CYP1B1 gene is low even among sporadic JOAG patients. Moreover, there is no clinical correlation between the presence of these mutations and disease severity. PMID- 29168044 TI - Potential selection bias in candidates for stereotactic radiotherapy for neovascular AMD. AB - PURPOSE: Stereotactic radiotherapy (SRT, IRay) was able to reduce the need for intravitreal injections of anti-VEGF (IVI) in patients with neovascular AMD (nAMD) in a phase II randomized clinical trial. Certain morphologic characteristics, such as lesion size < 4 mm2 or lack of fibrosis, were associated with a better response. The purpose of this cross-sectional study was to investigate eligibility for SRT in a clinical routine setting and to compare clinical features of eligible and non-eligible patients. METHODS: Cross-sectional study of 468 patients treated for nAMD in one study center within a period of 4 months. Clinical features, such as visual acuity or number of IVI since diagnosis and within 6/12 months, as well as the presence for exclusion criteria for SRT were analyzed. Exclusion criteria were sub-divided into lesion-associated (relevant fibrosis, lesion size > 4 mm2, PE tear), ocular comorbidity (e.g., macular comorbidity, vascular disease) and systemic comorbidity (e.g., dementia or tremor). RESULTS: Exclusion criteria were met by 255 patients (54.5%). Exclusion was most dominantly associated with lesion-associated criteria (80.0%) and less often with ocular (20.8%) or systemic (9.4%) comorbidity. A total of 213 patients (45.5%) fulfilled eligibility criteria. Eligible patients had a better VA at time of analysis (0.36 vs. 0.56 logMAR, p < 0.0001) and at baseline (0.38 vs. 0.56 logMAR, p < 0.0001) compared to non-eligible patients. The numbers of previous intravitreal injections since diagnosis in strictly PRN-treated patients served as a surrogate marker for lesion activity and was comparable within the last 6/12 months. Non-eligible patients had a higher number of different anti VEGF drugs (1.8 vs. 1.6, p = 0.038). CONCLUSIONS: SRT in addition to anti-VEGF can be an option in every second patient with nAMD. Due to morphological exclusion criteria, patients eligible for SRT had a better VA and a better clinical response compared to non-eligible patients. PMID- 29168045 TI - Biocompatibility of intravitreal injection of human mesenchymal stem cells in immunocompetent rabbits. AB - PURPOSE: To evaluate the feasibility, safety, and biocompatibility of intravitreal injection of human mesenchymal stem cells (MSCs) in immunocompetent pigmented rabbits. MATERIALS AND METHODS: Thirty-two pigmented rabbits (24 females, 8 males; Chinchilla-New Zealand White) were divided into 8 groups of 4 animals. Commercially prepared human MSCs were injected (0.05 ml) into the post lens vitreous of the right eyes. Groups 1 and 4 received isotonic medium (Ringer lactate-based), groups 2, 5, 7, and 8 received a low dose of 15 * 106 cells/ml. Groups 3 and 6 received a high dose of 30 * 106 cells/ml. Clinical signs were evaluated and scored before MSCs injection and weekly for 2 or 6 weeks. Animals were sacrificed at 2 or 6 weeks after injection. Eyes, liver, spleen, and gonads were assessed by histology and by fluorescent in situ hybridization to evaluate survival and extraocular migration of MSCs. RESULTS: There were no relevant clinical findings between control and MSC-injected rabbit eyes at any time point. There were also no relevant histological findings between control and MSC injected rabbits related to ocular, liver, spleen, or gonad tissues modifications. MSCs survived intravitreally for at least 2 weeks after injection. Extraocular migration of MSCs was not detected. CONCLUSIONS: MSCs are safe and well-tolerated when administered intravitreally at a dose of 15 * 106 cells/ml in pigmented rabbits. These findings enable future research to explore the intravitreal use of commercially prepared allogenic human MSCs in clinical trials of retinal diseases. PMID- 29168046 TI - Procalcitonin-guided antibiotic therapy in intensive care unit patients: a systematic review and meta-analysis. AB - BACKGROUND: Serum procalcitonin (PCT) concentration is used to guide antibiotic decisions in choice, timing, and duration of anti-infection therapy to avoid antibiotic overuse. Thus, we performed a systematic review and meta-analysis to seek evidence of different PCT-guided antimicrobial strategies for critically ill patients in terms of predefined clinical outcomes. METHODS: We searched for relevant studies in PubMed, Embase, Web of Knowledge, and the Cochrane Library up to 25 February 2017. Randomized controlled trials (RCTs) were included if they reported data on any of the predefined outcomes in adult ICU patients managed with a PCT-guided algorithm or according to standard care. Results were expressed as risk ratio (RR) or mean difference (MD) with accompanying 95% confidence interval (CI). DATA SYNTHESIS: We included 13 trials enrolling 5136 patients. These studies used PCT in three clinical strategies: initiation, discontinuation, or combination of antibiotic initiation and discontinuation strategies. Pooled analysis showed a PCT-guided antibiotic discontinuation strategy had fewer total days with antibiotics (MD - 1.66 days; 95% CI - 2.36 to - 0.96 days), longer antibiotic-free days (MD 2.26 days; 95% CI 1.40-3.12 days), and lower short-term mortality (RR 0.87; 95% CI 0.76-0.98), without adversely affecting other outcomes. Only few studies reported data on other PCT-guided strategies for antibiotic therapies, and the pooled results showed no benefit in the predefined outcomes. CONCLUSIONS: Our meta-analysis produced evidence that among all the PCT based strategies, only using PCT for antibiotic discontinuation can reduce both antibiotic exposure and short-term mortality in a critical care setting. PMID- 29168047 TI - Are Eating Disorders Risk Factors for Type 2 Diabetes? A Systematic Review and Meta-analysis. AB - RECENT FINDINGS: Eating disorders (ED) affect energy intake modifying body fat depots. Prior evidence suggests that binge eating disorder (BED) and bulimia nervosa (BN) could increase the risk for type 2 diabetes (T2D), while anorexia nervosa (AN) could reduce it. PURPOSE OF REVIEW: A systematic review and meta analysis were conducted to evaluate if ED are risk factors for T2D. Ten studies were selected out of 1057 screened. Meta-analysis of six studies with T2D as outcome is reported. Among cross-sectional studies, both BED (OR 3.69, 95% CI [1.12-12.12]) and BN (OR 3.45 [1.92-6.1]) increased the risk of T2D, while AN was not associated with lower risk (OR 0.87 [0.40-1.88]). Cohort studies showed increased risk of T2D with BN (RR 1.7 [1.2-2.5]), and decreased risk with AN (RR 0.71 [0.52-0.98]), but for BED the association was less clear (OR 3.34 [0.85 13.12]). Limitations of studies and recommendations for future research are presented. PMID- 29168048 TI - Homozygous Expression of Mutant ELOVL4 Leads to Seizures and Death in a Novel Animal Model of Very Long-Chain Fatty Acid Deficiency. AB - Lipids are essential components of the nervous system. However, the functions of very long-chain fatty acids (VLC-FA; >= 28 carbons) in the brain are unknown. The enzyme ELOngation of Very Long-chain fatty acids-4 (ELOVL4) catalyzes the rate limiting step in the biosynthesis of VLC-FA (Agbaga et al., Proc Natl Acad Sci USA 105(35): 12843-12848, 2008; Logan et al., J Lipid Res 55(4): 698-708, 2014), which we identified in the brain as saturated fatty acids (VLC-SFA). Homozygous mutations in ELOVL4 cause severe neuropathology in humans (Ozaki et al., JAMA Neurol 72(7): 797-805, 2015; Mir et al., BMC Med Genet 15: 25, 2014; Cadieux-Dion et al., JAMA Neurol 71(4): 470-475, 2014; Bourassa et al., JAMA Neurol 72(8): 942 943, 2015; Aldahmesh et al., Am J Hum Genet 89(6): 745-750, 2011) and are post natal lethal in mice (Cameron et al., Int J Biol Sci 3(2): 111-119, 2007; Li et al., Int J Biol Sci 3(2): 120-128, 2007; McMahon et al., Molecular Vision 13: 258 272, 2007; Vasireddy et al., Hum Mol Genet 16(5): 471-482, 2007) from dehydration due to loss of VLC-SFA that comprise the skin permeability barrier. Double transgenic mice with homozygous knock-in of the Stargardt-like macular dystrophy (STDG3; 797-801_AACTT) mutation of Elovl4 with skin-specific rescue of wild-type Elovl4 expression (S + Elovl4 mut/mut mice) develop seizures by P19 and die by P21. Electrophysiological analyses of hippocampal slices showed aberrant epileptogenic activity in S + Elovl4 mut/mut mice. FM1-43 dye release studies showed that synapses made by cultured hippocampal neurons from S + Elovl4 mut/mut mice exhibited accelerated synaptic release kinetics. Supplementation of VLC-SFA to cultured hippocampal neurons from mutant mice rescued defective synaptic release to wild-type rates. Together, these studies establish a critical, novel role for ELOVL4 and its VLC-SFA products in regulating synaptic release kinetics and epileptogenesis. Future studies aimed at understanding the molecular mechanisms by which VLC-SFA regulate synaptic function may provide new targets for improved seizure therapies. PMID- 29168050 TI - Using Gene Transcription to Assess Ecological and Anthropological Stressors in Brown Bears. AB - Increasingly, population- and ecosystem-level health assessments are performed using sophisticated molecular tools. Advances in molecular technology enable the identification of synergistic effects of multiple stressors on the individual physiology of different species. Brown bears (Ursus arctos) are an apex predator; thus, they are ideal candidates for detecting potentially ecosystem-level systemic perturbations using molecular-based tools. We used gene transcription to analyze 130 brown bear samples from three National Parks and Preserves in Alaska. Although the populations we studied are apparently stable in abundance and exist within protected and intact environments, differences in transcript profiles were noted. The most prevalent differences were among locations. The transcript patterns among groups reflect the influence of environmental factors, such as nutritional status, disease, and xenobiotic exposure. However, these profiles also likely represent baselines for each unique environment by which future measures can be made to identify early indication of population-level changes due to, for example, increasing Arctic temperatures. Some of those environmental changes are predicted to be potentially positive for brown bears, but other effects such as the manifestation of disease or indirect effects of oceanic acidification may produce negative impacts. PMID- 29168051 TI - Efficient conformational ensemble generation of protein-bound peptides. AB - Conformation generation of protein-bound peptides is critical for the determination of protein-peptide complex structures. Despite significant progress in conformer generation of small molecules, few methods have been developed for modeling protein-bound peptide conformations. Here, we have developed a fast de novo peptide modeling algorithm, referred to as MODPEP, for conformational sampling of protein-bound peptides. Given a sequence, MODPEP builds the peptide 3D structure from scratch by assembling amino acids or helix fragments based on constructed rotamer and helix libraries. The MODPEP algorithm was tested on a diverse set of 910 experimentally determined protein-bound peptides with 3-30 amino acids from the PDB and obtained an average accuracy of 1.90 A when 200 conformations were sampled for each peptide. On average, MODPEP obtained a success rate of 74.3% for all the 910 peptides and >= 90% for short peptides with 3-10 amino acids in reproducing experimental protein-bound structures. Comparative evaluations of MODPEP with three other conformer generation methods, PEP-FOLD3, RDKit, and Balloon, have also been performed in both accuracy and success rate. MODPEP is fast and can generate 100 conformations for less than one second. The fast MODPEP will be beneficial for large-scale de novo modeling and docking of peptides. The MODPEP program and libraries are available for download at http://huanglab.phys.hust.edu.cn/ . PMID- 29168053 TI - The sociobiology of genes: the gene's eye view as a unifying behavioural ecological framework for biological evolution. AB - Although classical evolutionary theory, i.e., population genetics and the Modern Synthesis, was already implicitly 'gene-centred', the organism was, in practice, still generally regarded as the individual unit of which a population is composed. The gene-centred approach to evolution only reached a logical conclusion with the advent of the gene-selectionist or gene's eye view in the 1960s and 1970s. Whereas classical evolutionary theory can only work with (genotypically represented) fitness differences between individual organisms, gene-selectionism is capable of working with fitness differences among genes within the same organism and genome. Here, we explore the explanatory potential of 'intra-organismic' and 'intra-genomic' gene-selectionism, i.e., of a behavioural-ecological 'gene's eye view' on genetic, genomic and organismal evolution. First, we give a general outline of the framework and how it complements the-to some extent-still 'organism-centred' approach of classical evolutionary theory. Secondly, we give a more in-depth assessment of its explanatory potential for biological evolution, i.e., for Darwin's 'common descent with modification' or, more specifically, for 'historical continuity or homology with modular evolutionary change' as it has been studied by evolutionary developmental biology (evo-devo) during the last few decades. In contrast with classical evolutionary theory, evo-devo focuses on 'within-organism' developmental processes. Given the capacity of gene-selectionism to adopt an intra-organismal gene's eye view, we outline the relevance of the latter model for evo-devo. Overall, we aim for the conceptual integration between the gene's eye view on the one hand, and more organism-centred evolutionary models (both classical evolutionary theory and evo-devo) on the other. PMID- 29168052 TI - Change in health-related quality of life and social cognitive outcomes in obese, older adults in a randomized controlled weight loss trial: Does physical activity behavior matter? AB - This article compared the effect of dietary weight loss administered alone (WL) or in combination with aerobic training (WL + AT) or resistance training (WL + RT) on health related quality of life, walking self-efficacy, stair climb self efficacy, and satisfaction with physical function in older adults with cardiovascular disease or the metabolic syndrome. Participants (N = 249; M age = 66.9) engaged in baseline assessments and were randomly assigned to one of three interventions, each including a 6-month intensive phase and a 12-month follow-up. Those in WL + AT and WL + RT engaged in 4 days of exercise training weekly. All participants engaged in weekly group behavioral weight loss sessions with a goal of 7-10% reduction in body weight. Participants in WL + AT and WL + RT reported better quality of life and satisfaction with physical function at 6- and 18 months relative to WL. At month 6, WL + AT reported greater walking self-efficacy relative to WL + RT and WL, and maintained higher scores compared to WL at month 18. WL + AT and WL + RT reported greater stair climbing efficacy at month 6, and WL + RT remained significantly greater than WL at month 18. The addition of either AT or RT to WL differentially improved HRQOL and key psychosocial outcomes associated with maintenance of physical activity and weight loss. This underscores the important role of exercise in WL for older adults, and suggests health care providers should give careful consideration to exercise mode when designing interventions. PMID- 29168054 TI - Cardiac function in patients with polymyositis or dermatomyositis: a three dimensional speckle-tracking echocardiography study. AB - Cardiac event is a major cause of death in patients with idiopathic inflammatory myopathies (IIM). The most frequent IIMs are polymyositis (PM) and dermatomyositis (DM). The purpose of this study was to analyze cardiac involvement by three-dimensional speckle-tracking echocardiography (3D STE) in patients with PM or DM, and to identify the relationship of cardiac injury with clinical characteristics and disease-specific parameters. 60 PM/DM patients with preserved left ventricular ejection fraction and 30 matched healthy controls were assessed by conventional echocardiography, 3D STE with biventricular strain analysis and electrocardiogram. Compared to controls, patients with PM/DM had significantly diminished left ventricular global longitudinal systolic strain and right ventricular longitudinal systolic strain (LVGLS, - 20.3 +/- 2.5 vs. - 23.4 +/- 1.7%; RVLS, - 19.4 +/- 4.2 vs - 24.8 +/- 2.0%; both P < 0.001), and longer QTc intervals(421.0 +/- 38.4 vs 400.6 +/- 14.5 ms, P = 0.001). Multiple regression analysis showed that Myositis Damage Index (MDI) was independently associated with LVGLS (R2 = 0.44, P = 0.002) and RVLS (R2 = 0.56, P < 0.001) in PM/DM patients with established disease course more than 1 year. In multivariate analysis of pooled data for all the PM/DM patients, when MDI was excluded due to missing observations, disease duration correlated with worse LVGLS (R2 = 0.24, P = 0.002), while concomitant interstitial lung disease correlated with worse RVLS (R2 = 0.30, P < 0.001). Disease activity scores (Myositis Intention to Treat Activities Index) had a weak positive correlation with QTc intervals (rsp = 0.31, P = 0.02). Our results suggest that cardiac injury in PM/DM is a long-term process and its severity depends on patients' heterogeneous clinical features and systemic disease burden. PMID- 29168055 TI - Reproducibility of peak filling and peak emptying rate determined by cardiovascular magnetic resonance imaging for assessment of biventricular systolic and diastolic dysfunction in patients with pulmonary arterial hypertension. AB - Right ventricular (RV) and left ventricular (LV) diastolic stiffness may be independent contributors to disease progression in pulmonary arterial hypertension (PAH). The aims of this study are to assess reproducibility of peak emptying rate (PER) and early diastolic peak filling rate (PFR) for both the RV and the LV in PAH and study their relationship to stroke volume (SV). Triple weekly repetition of 20 (totalling 60) cardiovascular magnetic resonance (CMR) scans, were done on 10 patients with PAH and 10 healthy controls. RV and LV volumes were measured over the full cardiac cycle. PER and PFR were calculated as the first derivative of the time-volume relationship in both the RV and the LV and indexed to body surface area. Reproducibility and the relation to SV were studied in a mixed model. PFR was lower in PAH in both the RV (PAH = 170 mL/m2/s, controls = 236 mL/m2/s [p < 0.01]) and in the LV (PAH = 209 mL/m2/s, controls = 311 mL/m2/s [p < 0.01]). PERs were not significantly different between patients and controls. Reproducibility of PER and PFR was high. A trial targeting normalization of PFR requires a total sample size of < 20. PER and PFR in both ventricles were strongly associated with stroke volume (all four: p < 0.01). Biventricular diastolic dysfunctions are strongly associated with stroke volume, and CMR can quantify them with high reproducibility, enabling small sample sizes for trials of therapies targeting diastolic dysfunction to increase survival. PMID- 29168056 TI - In vivo therapeutic potential of Inula racemosa in hepatic ischemia-reperfusion injury following orthotopic liver transplantation in male albino rats. AB - Hepatic ischemia-reperfusion (I/R) injury mainly occurs following hepatic resection and liver transplantation and cause severe liver damage, organ injuries, and dysfunction. Pro-inflammatory cytokines that promote injury are released when kupffer cell activates after getting induced by I/R. Repercussions of oxidative stress and cardiac function against isoproterenol based myocardial infarction are caused by flavonol glycosides which are found in high concentrations in Inula racemosa (Ir).The root was deemed to have analgesic and anti-inflammatory effects, and no report has been published about the liver protective activity against hepatic I/R. Therefore, the present study was aimed to understand the therapeutic impact of Ir in hepatic I/R injury. Male albino, Wistar strain rats were used and were grouped into four total phenolic content, free radical scavenging activity and serum enzymes were determined. Histopathological and immunohistochemical analysis were also carried out. Inflammatory cytokines such as tumor necrosis factor-alpha (TNF-alpha) and interleukin (IL-6) and protein expression of p53, bax, and bcl-2 were determined. The administration of extracts of Ir significantly increased total phenolic and free radical scavenging activity. Altered cellular morphology, cytokines and aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) were returned to near normal level. IL-6 and TNF-alpha levels were reduced more than 25% following treatment. Also, the protein expression of p53, bax, and bcl-2 were also returned to near normal level. Taking all these data together, it is suggested that the extracts of Ir may be a potential therapeutic agent for providing several beneficial effects in hepatic I/R injury. PMID- 29168057 TI - 1H, 15N and 13C backbone resonance assignments of pentaerythritol tetranitrate reductase from Enterobacter cloacae PB2. AB - Pentaerythritol tetranitrate reductase (PETNR) is a flavoenzyme possessing a broad substrate specificity and is a member of the Old Yellow Enzyme family of oxidoreductases. As well as having high potential as an industrial biocatalyst, PETNR is an excellent model system for studying hydrogen transfer reactions. Mechanistic studies performed with PETNR using stopped-flow methods have shown that tunneling contributes towards hydride transfer from the NAD(P)H coenzyme to the flavin mononucleotide (FMN) cofactor and fast protein dynamics have been inferred to facilitate this catalytic step. Herein, we report the near-complete 1H, 15N and 13C backbone resonance assignments of PETNR in a stoichiometric complex with the FMN cofactor in its native oxidized form, which were obtained using heteronuclear multidimensional NMR spectroscopy. A total of 97% of all backbone resonances were assigned, with 333 out of a possible 344 residues assigned in the 1H-15N TROSY spectrum. This is the first report of an NMR structural study of a flavoenzyme from the Old Yellow Enzyme family and it lays the foundation for future investigations of functional dynamics in hydride transfer catalytic mechanism. PMID- 29168058 TI - Analysis of Siamese Crocodile (Crocodylus siamensis) Eggshell Proteome. AB - The proteins and pigment of the eggshell of the Siamese crocodile (Crocodylus siamensis) were analysed. For proteomic analysis, various decalcification methods were used when the two main surface layers were analyzed. These layers are important for antimicrobial defense of egg (particularly the cuticle). We found 58 proteins in both layers, of which 4 were specific for the cuticle and 26 for the palisade (honeycomb) layer. Substantial differences between proteins in the eggshell of crocodile and previously described birds' eggshells exist (both in terms of quality and quantity), however, the entire proteome of Crocodilians has not been described yet. The most abundant protein was thyroglobulin. The role of determined proteins in the eggshell of the Siamese crocodile is discussed. For the first time, the presence of porphyrin pigment is reported in a crocodilian eggshell, albeit in a small amount (about 2 to 3 orders of magnitude lower than white avian eggs). PMID- 29168059 TI - Sec61beta facilitates the maintenance of endoplasmic reticulum homeostasis by associating microtubules. AB - Sec61beta, a subunit of the Sec61 translocon complex, is not essential in yeast and commonly used as a marker of endoplasmic reticulum (ER). In higher eukaryotes, such as Drosophila, deletion of Sec61beta causes lethality, but its physiological role is unclear. Here, we show that Sec61beta interacts directly with microtubules. Overexpression of Sec61beta containing small epitope tags, but not a RFP tag, induces dramatic bundling of the ER and microtubule. A basic region in the cytosolic domain of Sec61beta is critical for microtubule association. Depletion of Sec61beta induces ER stress in both mammalian cells and Caenorhabditis elegans, and subsequent restoration of ER homeostasis correlates with the microtubule binding ability of Sec61beta. Loss of Sec61beta causes increased mobility of translocon complexes and reduced level of membrane-bound ribosomes. These results suggest that Sec61beta may stabilize protein translocation by linking translocon complex to microtubule and provide insight into the physiological function of ER-microtubule interaction.

AB - Chinese Americans have low colorectal cancer (CRC) screening rates. It is unclear whether physicians should offer all CRC screening modalities (fecal occult blood test [FOBT], sigmoidoscopy, colonoscopy) to Chinese Americans to increase screening. Seven hundred and twenty-five Chinese Americans were asked in a survey if their physician had ever recommended CRC screening and to self-report receipt and type of CRC screening. Participants whose physician had recommended all CRC screening modalities were significantly more likely to report ever having screening (adjusted odds ratio 4.29, 95% CI 1.26-14.68) and being up-to-date (4.06, 95% CI 2.13-7.74) than those who reported that their physician only recommended FOBT. Participants who received a recommendation of only one type of screening did not report a significant difference in ever having or being up-to date for screening. A potential strategy to increase CRC screening among Chinese Americans is for clinicians to recommend all available CRC screening modalities to each patient. PMID- 29168062 TI - Tree nut, peanut, and peanut butter intake and risk of postmenopausal breast cancer: The Netherlands Cohort Study. AB - PURPOSE: Nut intake has been associated with reduced mortality and risk of cardiovascular diseases, but there is only limited evidence on cancer. We investigated the relationship between nut intake and risk of postmenopausal breast cancer, and estrogen/progesterone receptor (ER/PR) subtypes. METHODS: In The Netherlands Cohort Study, 62,573 women aged 55-69 years provided information on dietary and lifestyle habits in 1986. After 20.3 years of follow-up, 2,321 incident breast cancer cases and 1,665 subcohort members were eligible for multivariate case-cohort analyses. RESULTS: Total nut intake was significantly inversely related to ER negative (ER -) breast cancer risk, with HR 0.55 (95% CI 0.33-0.93) for those consuming at least 10 g nuts/day versus non-consumers (p trend = 0.025). There were no significant inverse associations with ER + or total breast cancer. While there was no variation between PR subtypes, the ER-PR- subtype was also significantly inversely associated with nut intake, with HR 0.53 (95% CI 0.29-0.99), p trend = 0.037. Intake of peanuts and tree nuts separately was also inversely related to ER - breast cancer subtypes, while no associations were found with peanut butter intake. CONCLUSIONS: Our findings suggest an inverse association between nut intake and ER - breast cancer, and no association with total or hormone receptor-positive subtypes. PMID- 29168063 TI - Abundant tumor infiltrating lymphocytes after primary systemic chemotherapy predicts poor prognosis in estrogen receptor-positive/HER2-negative breast cancers. AB - PURPOSE: The therapeutic effect of systemic treatment for breast cancer (BC) generally depends on its intrinsic subtypes. In addition, tumor infiltrating lymphocytes (TILs) are considered to be an independent factor for tumor shrinkage and disease prognosis. High TILs at baseline or after primary systemic chemotherapy are reported to be associated with better survival in triple negative or human epithelial growth factor receptor 2 (HER2)-positive BCs. However, the prognostic value of TILs in estrogen receptor (ER)-positive and HER2 negative (ER+/HER2-) BC is still controversial. METHODS: We assessed TIL score (low, intermediate, and high) before and after primary systemic chemotherapy in every subtype of BC, and compared the clinical outcomes. Biopsy specimens of 47 triple-negative, 58 HER2+ and 91 ER+/HER2- BCs were used to assess TILs before treatment. To assess TILs after treatment, we examined residual invasive carcinoma in surgically resected samples of 28 triple-negative, 30 HER2+ and 80 ER+/HER2- BCs. RESULTS: A high TIL score in triple-negative BC before treatment resulted in a significantly higher proportion of pathological complete response (pCR). In contrast, ER+/HER2- BC exhibited fewer instances of pCR than other subtypes. Although not statistically significant, ER+/HER2- cases with a high TIL score also tended to achieve pCR (p = 0.088). Moreover, we revealed that low TIL BCs after chemotherapy, but not at baseline, had significantly better relapse free survival in ER+/HER2- BC (p = 0.034). CONCLUSION: Pathological examination of TILs after treatment may be a surrogate marker for prognosis in ER+/HER2- BC. PMID- 29168064 TI - Adipose tissue inflammation in breast cancer survivors: effects of a 16-week combined aerobic and resistance exercise training intervention. AB - PURPOSE: Obesity is a leading modifiable contributor to breast cancer mortality due to its association with increased recurrence and decreased overall survival rate. Obesity stimulates cancer progression through chronic, low-grade inflammation in white adipose tissue, leading to accumulation of adipose tissue macrophages (ATMs), in particular, the pro-inflammatory M1 phenotype macrophage. Exercise has been shown to reduce M1 ATMs and increase the more anti-inflammatory M2 ATMs in obese adults. The purpose of this study was to determine whether a 16 week exercise intervention would positively alter ATM phenotype in obese postmenopausal breast cancer survivors. METHODS: Twenty obese postmenopausal breast cancer survivors were randomized to a 16-week aerobic and resistance exercise (EX) intervention or delayed intervention control (CON). The EX group participated in 16 weeks of supervised exercise sessions 3 times/week. Participants provided fasting blood, dual-energy X-ray absorptiometry (DXA), and superficial subcutaneous abdominal adipose tissue biopsies at baseline and following the 16-week study period. RESULTS: EX participants experienced significant improvements in body composition, cardiometabolic biomarkers, and systemic inflammation (all p < 0.03 vs. CON). Adipose tissue from EX participants showed a significant decrease in ATM M1 (p < 0.001), an increase in ATM M2 (p < 0.001), increased adipose tissue secretion of anti-inflammatory cytokines such as adiponectin, and decreased secretion of the pro-inflammatory cytokines IL-6 and TNF- alpha (all p < 0.055). CONCLUSIONS: A 16-week aerobic and resistance exercise intervention attenuates adipose tissue inflammation in obese postmenopausal breast cancer survivors. Future large randomized trials are warranted to investigate the impact of exercise-induced reductions in adipose tissue inflammation and breast cancer recurrence. PMID- 29168065 TI - Are VNTRs co-localizing with breast cancer-associated SNPs? AB - PURPOSE: Several common genetic variants (single-nucleotide polymorphisms, SNPs) have been shown to be associated with breast cancer (BC) risk in the general population, and to modify BC risk for BRCA1 and BRCA2 mutation carriers. Co localization of variable number of tandem repeats (VNTRs) with these BC associated SNPS has not been comprehensively studied. METHODS: Cross referencing of genome-wide VNTRs with the known BC genome-wide association studies (GWAS) SNPs significantly associated with increased risk for developing breast cancer was carried out. Analysis was based on the overlap between the VNTRs and 10-kb windows around these BC-susceptibility SNPs. RESULTS: Cross referencing of the 1.2 million TR with the 161 known BC-associated SNPs in the general population led to 690 matches. Of those, in 17 VNTRs, the SNP was within the VNTR. Analysis restricted to loci known to modify BC penetrance in BRCA1 (n = 31) and BRCA2 (n = 33) mutation carriers led to 139 and 170 co-localization matches, respectively. For these, none of the SNPs were within the VNTR. The distances between the SNPs and the VNTRs were not significantly different from what was expected to occur by chance alone (p = 0.61; p = 0.44; p = 0.25, respectively). CONCLUSION: There is no evidence that VNTRs co-localize with currently reported SNP tagged BC GWAS loci. PMID- 29168066 TI - Changes in Anxiety and Depression Symptoms Predict Sexual Risk Behaviors Among Young Men Living in Dar es Salaam, Tanzania. AB - Young men are important targets in HIV prevention in Tanzania and throughout sub Saharan Africa. Anxiety and depression are common among youth and may be important predictors of HIV risk behaviors; evidence of these relationships in high-risk populations is needed. Using baseline and 1 year follow-up assessments from an HIV prevention trial we assessed the association between changes in symptoms of anxiety and depression and follow-up sexual risk behaviors (condom use and sexual partner concurrency) controlling for baseline sexual risk behaviors among 1113 male members of social groups known as "camps" in Dar es Salaam, Tanzania. Anxiety and depression were measured using the HSCL-25 and condom use and sexual partner concurrency were assessed through self-report. In separate models, increases in anxiety and depression were associated with sexual partner concurrency and with lower levels of condom use. In a combined model, both anxiety and depression appeared to independently affect concurrency but only depression was independently associated with condom use, with the association between anxiety and condom use being likely attributable to covariance with depression symptoms. The results of this study indicate the importance of screening and providing treatment for depression and anxiety disorders in high HIV-prevalence contexts, and the need to develop effective HIV prevention interventions targeting young men living with anxiety and depression. PMID- 29168067 TI - Continued Transmission of HIV Among Young Adults Who Inject Drugs in San Francisco: Still Room for Improvement. AB - We measured HIV incidence rate, trend and risk factors in 564 HIV-negative young people (< 30 years) who inject drugs (PWID) in San Francisco between 2000 and 2014. HIV incidence was 0.93/100 person-years (PY; 95% CI 0.50, 1.73). Incidence varied between 0.62/100 PY in 2000-2002 and 1.06/100 PY in 2012-2014 (P for trend = 1.0). HIV incidence varied significantly (P < 0.01) by race/ethnicity: among Hispanics it was 8.19/100 PY (95% CI 3.41, 19.68), African-Americans 4.59/100 PY (95% CI 1.15, 18.37), and Whites 0.26/100 PY (95% CI 0.06, 1.03). Male participants who reported sex with men (MSM) had higher HIV incidence (2.63/100 PY; 95% CI 1.31, 5.25) compared to males who did not report MSM (0.50/100 PY; 95% CI 0.12, 1.99) (P = 0.01). Despite an overall stable HIV incidence trend, incidence was elevated among African-American and Hispanic PWID, and men who have sex with men. Addressing prevention needs in these key populations is critical for the goal of eliminating HIV transmission. PMID- 29168068 TI - Predicting Arrest in a Sample of Youth Perinatally Exposed to HIV: The Intersection of HIV and Key Contextual Factors. AB - We examined the role of youth HIV status and other key factors on past-year arrest in perinatally HIV-exposed but uninfected (PHIV-) and perinatally HIV infected (PHIV+) youth using data from a multi-site study of psychosocial behaviors in PHIV-exposed urban youth (N = 340; 61% PHIV+; 51% female; ages 9-16 at baseline). Youth and caregivers were administered 5 interviews, spanning approximately 7.5 years. Using longitudinal logistic mixed-effect models, we explored the association between past year arrest, internal [e.g., substance use disorder (SUD)] and external (e.g., neighborhood arrest rates) contextual factors, and social-regulation processes (e.g., in-school/work). Arrest rates increased from 2.6 to 19.7% across follow-ups; there were no differences in arrest over time by HIV status. In the final model, odds of arrest were greater for youth who were male, with SUD, >= 18 years old, with high levels of city stress, and neither in school nor employed. PHIV-exposed, urban youth have much higher rates of arrest than national samples. Lack of differences in arrest by HIV status suggests key contextual factors are more important in promoting arrest. PMID- 29168069 TI - Sexual Stigma Patterns Among Nigerian Men Who Have Sex with Men and Their Link to HIV and Sexually Transmitted Infection Prevalence. AB - Sexual stigma facilitates the spread of HIV and sexually transmitted infections (STIs) but little is known about stigma affecting Nigerian men who have sex with men (MSM). We assessed patterns of sexual stigma across Nigerian MSM and their relationship to HIV and STIs. Data were collected from the TRUST/RV368 Study, a prospective cohort of 1480 Nigerian MSM enrolled from March 2013 to February 2016 using respondent driven sampling. Structural equation modeling was utilized to assess the association between stigma classes and HIV and STI prevalence, adjusting for participants' characteristics. A dose-response association was found between stigma class and HIV prevalence (27, 40, 55%, overall chi2 p < 0.001) and STI prevalence (15, 21, 24%, overall chi2 p = 0.011). These data suggest that stigma mitigation strategies, combined with increased engagement of MSM and retention in the HIV care continuum, need to be a component of interventions focused on reducing HIV transmission risks among MSM in Nigeria. PMID- 29168070 TI - Arterial pulse attenuation prediction using the decaying rate of a pressure wave in a viscoelastic material model. AB - The present study examines the possibility of attenuating blood pulses by means of introducing prosthetic viscoelastic materials able to absorb energy and damp such pulses. Vascular prostheses made of polymeric materials modify the mechanical properties of blood vessels. The effect of these materials on the blood pulse propagation remains to be fully understood. Several materials for medical applications, such as medical polydimethylsiloxane or polytetrafluoroethylene, show viscoelastic behavior, modifying the original vessel stiffness and affecting the propagation of blood pulses. This study focuses on the propagation of pressure waves along a pipe with viscoelastic materials using the Maxwell and the Zener models. An expression of exponential decay has been obtained for the Maxwell material model and also for low viscous coefficient values in the Zener model. For relatively high values of the viscous term in the Zener model, the steepest part of the pulse can be damped quickly, leaving a smooth, slowly decaying wave. These mathematical models are critical to tailor those materials used in cardiovascular implants to the mechanical environment they are confronted with to repair or improve blood vessel function. PMID- 29168071 TI - Influence of functionally graded pores on bone ingrowth in cementless hip prosthesis: a finite element study using mechano-regulatory algorithm. AB - Cementless hip prostheses with porous outer coating are commonly used to repair the proximally damaged femurs. It has been demonstrated that stability of prosthesis is also highly dependent on the bone ingrowth into the porous texture. Bone ingrowth is influenced by the mechanical environment produced in the callus. In this study, bone ingrowth into the porous structure was predicted by using a mechano-regulatory model. Homogenously distributed pores (200 and 800 [Formula: see text]m in diameter) and functionally graded pores along the length of the prosthesis were introduced as a porous coating. Bone ingrowth was simulated using 25 and 12 [Formula: see text]m micromovements. Load control simulations were carried out instead of traditionally used displacement control. Spatial and temporal distributions of tissues were predicted in all cases. Functionally graded pore decreasing models gave the most homogenous bone distribution, the highest bone ingrowth (98%) with highest average Young's modulus of all tissue phenotypes approximately 4.1 GPa. Besides this, the volume of the initial callus increased to 8.33% in functionally graded pores as compared to the 200 [Formula: see text]m pore size models which increased the bone volume. These findings indicate that functionally graded porous surface promote bone ingrowth efficiently which can be considered to design of surface texture of hip prosthesis. PMID- 29168072 TI - Estimates for the acoustical stimulation and heating of multiphase biotissue. AB - Low-intensity, unfocused, ultrasound-induced diathermy can produce undesired temperature increases at the interface of adjacent tissues within the body; particularly, at the interface of soft tissue and bone. This study provides a computational framework for predicting an upper bound on the temperature profile within a multiphase system composed of gel pad (water), tissue and bone from an input of acoustic energy, at frequencies and power levels consistent with applications of therapeutic hyperthermia. The model consists of solving a (one dimensional) spatially discretized bioheat transfer equation via finite difference method and updating the solution in time with a forward-Euler scheme. Simulations are then compared to experimental data to determine the energy-to heat conversion factors within each constituent material using thermocouple embedded, tissue-mimicking phantom material, with and without bone. Viscous heating artifacts from the presence of the thermocouples in the experimental phantom tissue are accounted for via additional experimental methods similar to those described by Morris et al. (Phys Med Biol 53:4759, 2008). Finally, an example application of the model is presented via prediction of the maximum temperature at the tissue-bone interface, as well as the peak temperatures in the composite structure at the end of a prescribed 2-min sonication, of blood perfused, human soft-tissue at 1, 2 and 3 MHz frequencies and a spatial peak temporally averaged intensity of [Formula: see text]. The results of this simulation are then related to comparable experimental studies in the literature. PMID- 29168074 TI - Paleoanthropology's uses of the bipedal criterion. AB - Bipedalism is one of the criteria that paleoanthropologists use in order to interpret the fossil record and to determine if a specimen belongs to the human lineage. In the context of such interpretations, bipedalism is considered to be a unique characteristic of this lineage that also marks its origin. This conception has largely remained unchallenged over the last decades, in spite of fossil discoveries that led to the emergence of bipedalism in the human lineage being shifted back by several millions of years. In this paper, I analyze the uses of this criterion in paleoanthropology and demonstrate that interpretative biases (such as underdetermined inferences and circular reasoning) are at play in interpretations of hominin remains. By discussing Darwin's hypotheses about the evolution of bipedalism, I identify major theoretical issues that need to be addressed in the current debates on hominin evolution. First, the assumption that "man alone has become a biped" (Darwin in The descent of man, and selection in relation to sex, John Murray, London, 1871) is analyzed in the light of recent empirical data. Three major issues are discussed: the definition of "man", i.e. "human", the uniqueness of human bipedalism, and the equivocal meaning of being a "biped". Then, I highlight some of Darwin's remarks that may be helpful for current debates in paleoanthropology, regarding natural selection in locomotor evolution, as well as taxonomic and phylogenetic significance of functional features. Finally, I analyze two examples of how fossil discoverers referred to Darwin in the recent years and discuss his role as an intellectual support. PMID- 29168073 TI - Fungus-Specific CD4 T Cells as Specific Sensors for Identification of Pulmonary Fungal Infections. AB - Patients with cystic fibrosis (CF) suffer from chronic lung infections, caused by bacterial, viral or fungal pathogens, which determine morbidity and mortality. The contribution of individual pathogens to chronic disease and acute lung exacerbations is often difficult to determine due to the complex composition of the lung microbiome in CF. In particular, the relevance of fungal pathogens in CF airways remains poorly understood due to limitations of current diagnostics to identify the presence of fungal pathogens and to resolve the individual host pathogen interaction status. T-lymphocytes play an essential role in host defense against pathogens, but also in inappropriate immune reactions such as allergies. They have the capacity to specifically recognize and discriminate the different pathogens and orchestrate a diverse array of effector functions. Thus, the analysis of the fungus-specific T cell status of an individual can in principle provide detailed information about the identity of the fungal pathogen(s) encountered and the actual fungus-host interaction status. This may allow to classify patients, according to appropriate (protective) or inappropriate (pathology-associated) immune reactions against individual fungal pathogens. However, T cell-based diagnostics are currently not part of the clinical routine. The identification and characterization of fungus-specific T cells in health and disease for diagnostic purposes are associated with significant challenges. Recent technological developments in the field of fungus-specific T helper cell detection provide new insights in the host T cell-fungus interaction. In this review, we will discuss basic principles and the potential of T cell-based diagnostics, as well as the perspectives and further needs for use of T cells for improved clinical diagnostics of fungal diseases. PMID- 29168076 TI - Model-Based Methods in the Biopharmaceutical Process Lifecycle. AB - Model-based methods are increasingly used in all areas of biopharmaceutical process technology. They can be applied in the field of experimental design, process characterization, process design, monitoring and control. Benefits of these methods are lower experimental effort, process transparency, clear rationality behind decisions and increased process robustness. The possibility of applying methods adopted from different scientific domains accelerates this trend further. In addition, model-based methods can help to implement regulatory requirements as suggested by recent Quality by Design and validation initiatives. The aim of this review is to give an overview of the state of the art of model based methods, their applications, further challenges and possible solutions in the biopharmaceutical process life cycle. Today, despite these advantages, the potential of model-based methods is still not fully exhausted in bioprocess technology. This is due to a lack of (i) acceptance of the users, (ii) user friendly tools provided by existing methods, (iii) implementation in existing process control systems and (iv) clear workflows to set up specific process models. We propose that model-based methods be applied throughout the lifecycle of a biopharmaceutical process, starting with the set-up of a process model, which is used for monitoring and control of process parameters, and ending with continuous and iterative process improvement via data mining techniques. PMID- 29168075 TI - Pharmacogenetics of Methadone Response. AB - The efficacy of methadone maintenance treatment (MMT) in opioid use disorder is well established but responses vary. The influence of methadone pharmacodynamics and pharmacokinetics on dose requirements and program outcomes remains controversial despite the increasing number of studies evaluating genetic influences on response to methadone treatment. Furthermore, patients require different doses (usually between 60 and 100 mg/day), and there are no clear data on a plasma concentration associated with treatment success. We review the evidence regarding the influence of genetics on pharmacokinetic and pharmacodynamic factors in terms of MMT outcome. We also analyse the influence of genetics on the occurrence of severe adverse events such as respiratory depression and ventricular arrhythmia in methadone treatment. The outcomes of MMT may be influenced by a combination of environmental, drug-induced, and genetic factors. The influence of pharmacokinetic genetic variability can be clinically managed by modifying the posology. A better understanding of pharmacodynamic factors could help in selecting the best opioid for substitution treatment, but patient phenotype must still be considered when establishing a maintenance treatment. Pharmacogenetic studies represent a promising field that aims to individualize treatments according to genetic backgrounds, adapting medication and doses according to possible outcomes and the risk of adverse events. PMID- 29168077 TI - Progress and challenges of sequencing and analyzing circulating tumor cells. AB - Circulating tumor cells (CTCs) slough off primary tumor tissues and are swept away by the circulatory system. These CTCs can remain in circulation or colonize new sites, forming metastatic clones in distant organs. Recently, CTC analyses have been successfully used as effective clinical tools to monitor tumor progression and prognosis. With advances in next-generation sequencing (NGS) and single-cell sequencing (SCS) technologies, scientists can obtain the complete genome of a CTC and compare it with corresponding primary and metastatic tumors. CTC sequencing has been successfully applied to monitor genomic variations in metastatic and recurrent tumors, infer tumor evolution during treatment, and examine gene expression as well as the mechanism of the epithelial-mesenchymal transition. However, compared with cancer biopsy sequencing and circulating tumor DNA sequencing, the sequencing of CTC genomes and transcriptomes is more complex and technically difficult. Challenges include enriching pure tumor cells from a background of white blood cells, isolating and collecting cells without damaging or losing DNA and RNA, obtaining unbiased and even whole-genome and transcriptome amplification material, and accurately analyzing CTC sequencing data. Here, we review and summarize recent studies using NGS on CTCs. We mainly focus on CTC genome and transcriptome sequencing and the biological and potential clinical applications of these methodologies. Finally, we discuss challenges and future perspectives of CTC sequencing. PMID- 29168078 TI - The effect of hypergastrinemia following sleeve gastrectomy and pantoprazole on type 2 diabetes mellitus and beta-cell mass in Goto-Kakizaki rats. AB - PURPOSE: Metabolic surgery alters the secretion of gastrointestinal hormones that influence glycemic control. Elevated gastrin has been suggested to benefit patients with type 2 diabetes and has been reported following sleeve gastrectomy in rats. The present study compares the effect of hypergastrinemia following sleeve gastrectomy with proton-pump inhibitor therapy on glycemic control and beta-cell mass in lean, diabetic animals. METHODS: Thirty-three diabetic Goto Kakizaki rats were randomized into pantoprazole + sham operation (GK-PPI), sleeve gastrectomy (GK-SG) and vehicle + sham operation (GK-V). Body weight, glucose parameters, HbA1c, glucagon-like peptide 1, gastrin, insulin and lipids were evaluated for eighteen postoperative weeks. Total beta-cell mass was quantified by optical projection tomography. RESULTS: After surgery, body weight development was equal among groups (P g = 0.75). Fasting and stimulated gastrin increased for GK-PPI and GK-SG vs. GK-V (p < 0.05 for all). Fasting blood glucose was decreased for GK-PPI and GK-SG vs. GK-V (p < 0.05 and p = 0.052). HbA1c was lower for GK-SG vs. GK-V at 6 weeks and for GK-PPI vs. GK-V at twelve- and eighteen weeks postoperative (p < 0.05 for all); a borderline difference was observed for GK-SG vs. GK-V at 18 weeks (p = 0.054). Total- and LDL cholesterol was elevated for GK PPI compared to the other two groups (p < 0.05 for all). Beta-cell mass did not differ among groups (p = 0.35). CONCLUSIONS: Hypergastrinemia following sleeve gastrectomy and pantoprazole has a similar, modest effect on glycemic control in Goto-Kakizaki rats but does not enhance beta-cell mass after 18 weeks. Hypergastrinemia in the setting of T2DM might be of clinical relevance. PMID- 29168079 TI - Use of Mixture Designs to Investigate Contribution of Minor Sex Pheromone Components to Trap Catch of the Carpenterworm Moth, Chilecomadia valdiviana. AB - Field experiments were carried out to study responses of male moths of the carpenterworm, Chilecomadia valdiviana (Lepidoptera: Cossidae), a pest of tree and fruit crops in Chile, to five compounds previously identified from the pheromone glands of females. Previously, attraction of males to the major component, (7Z,10Z)-7,10-hexadecadienal, was clearly demonstrated while the role of the minor components was uncertain due to the use of an experimental design that left large portions of the design space unexplored. We used mixture designs to study the potential contributions to trap catch of the four minor pheromone components produced by C. valdiviana. After systematically exploring the design space described by the five pheromone components, we concluded that the major pheromone component alone is responsible for attraction of male moths in this species. The need for appropriate experimental designs to address the problem of assessing responses to mixtures of semiochemicals in chemical ecology is described. We present an analysis of mixture designs and response surface modeling and an explanation of why this approach is superior to commonly used, but statistically inappropriate, designs. PMID- 29168080 TI - Cardioprotective Effects of Morroniside in Rats Following Acute Myocardial Infarction. AB - The aim of this study is to investigate the cardioprotective effects of morroniside in rats following acute myocardial infarction. An acute myocardial infarction (AMI) was induced by ligating the anterior descending coronary artery (LAD) [1]. Following AMI, morroniside was administered intragastrically for 24 h at doses of 45, 90, and 180 mg/kg, respectively. Biomarkers such as creatine kinase (CK-MB), lactate dehydrogenase (LDH), alpha-hydroxybutyrate dehydrogenase (alpha-HBDH), and aspartate aminotransferase (AST) activities in AMI rats in the serum were detected with commercial kits [2]. Following AMI, morroniside was administered intragastrically for 72 h at doses of 45, 90, and 180 mg/kg/d, respectively. The expression of nuclear factor kappa B (NF-kappaB) in cardiac myocardium was detected by western blotting analysis. Meanwhile, cardiac function was measured by echocardiography. We observed morroniside decreased the levels of CK-MB, LDH, alpha-HBDH, and AST activities in AMI rats after 24 h. We also found that morroniside reduced the expression of NF-kappaB in cardiac myocardium at 72 h post AMI rats. Further, cardiac function was improved by administration of morroniside. Collectively, our findings demonstrated that morroniside had cardioprotective effects in rats following acute myocardial infarction. Attenuation of inflammation might contribute to the cardioprotective effects of morroniside. PMID- 29168081 TI - High Glucose Stimulates Expression of MFHAS1 to Mitigate Inflammation via Akt/HO 1 Pathway in Human Umbilical Vein Endothelial Cells. AB - Hyperglycemia is a highly dangerous factor to various diseases, even resulting in death of people. Inflammation plays a key role in this process. The aim of this study was to explore the role of malignant fibrous histiocytoma amplified sequence 1 (MFHAS1) in high-glucose induced inflammation. Our research showed that high glucose stimulated the expression of MFHAS1, and overexpression of MFHAS1 can attenuate high-glucose induced inflammation in endothelial cells by decreasing the secretion of cytokines interleukin-1beta (IL-1beta), interleukin 1alpha (IL-1alpha), adhesion molecule intercellular adhesion molecule-1 (ICAM), interleukin-6 (IL-6), interleukin-8 (IL-8), and chemokine ligand 1 (CXCL-1). Furthermore, we found that MFHAS1 promoted the phosphorylation of Akt and the expression of heme oxygenase-1 (HO-1). Our results indicated that MFHAS1 deadened high-glucose induced inflammation by activating AKT/HO-1 pathway, suggesting that MFHAS1 may act as a new therapeutic target of diabetes mellitus. PMID- 29168083 TI - Analysis of the cancer genome atlas (TCGA) database identifies an inverse relationship between interleukin-13 receptor alpha1 and alpha2 gene expression and poor prognosis and drug resistance in subjects with glioblastoma multiforme. AB - Glioblastoma multiforme (GBM) is the most common primary brain tumor in adults. A variety of targeted agents are being tested in the clinic including cancer vaccines, immunotoxins, antibodies and T cell immunotherapy for GBM. We have previously reported that IL-13 receptor subunits alpha1 and alpha2 of IL-13R complex are overexpressed in GBM. We are investigating the significance of IL 13Ralpha1 and alpha2 expression in GBM tumors. In order to elucidate a possible relationship between IL-13Ralpha1 and alpha2 expression with severity and prognoses of subjects with GBM, we analyzed gene expression (by microarray) and clinical data available at the public The Cancer Genome Atlas (TCGA) database (Currently known as Global Data Commons). More than 40% of GBM samples were highly positive for IL-13Ralpha2 mRNA (Log2 >= 2) while only less than 16% samples were highly positive for IL-13Ralpha1 mRNA. Subjects with high IL 13Ralpha1 and alpha2 mRNA expressing tumors were associated with a significantly lower survival rate irrespective of their treatment compared to subjects with IL 13Ralpha1 and alpha2 mRNA negative tumors. We further observed that IL-13Ralpha2 gene expression is associated with GBM resistance to temozolomide (TMZ) chemotherapy. The expression of IL-13Ralpha2 gene did not seem to correlate with the expression of genes for other chains involved in the formation of IL-13R complex (IL-13Ralpha1 or IL-4Ralpha) in GBM. However, a positive correlation was observed between IL-4Ralpha and IL-13Ralpha1 gene expression. The microarray data of IL-13Ralpha2 gene expression was verified by RNA-Seq data. In depth analysis of TCGA data revealed that immunosuppressive genes (such as FMOD, CCL2, OSM, etc.) were highly expressed in IL-13Ralpha2 positive tumors, but not in IL 13Ralpha2 negative tumors. These results indicate a direct correlation between high level of IL-13R mRNA expression and poor patient prognosis and that immunosuppressive genes associated with IL-13Ralpha2 may play a role in tumor progression. These findings have important implications in understanding the role of IL-13R in the pathogenesis of GBM and potentially other cancers. PMID- 29168082 TI - A pilot study of neuropsychological functions, APOE and amyloid imaging in patients with gliomas. AB - Brain tumor patients treated with radiotherapy (RT) often develop cognitive dysfunction, and recent studies suggest that the APOE epsilon-4 allele may influence cognitive outcome. The epsilon-4 allele is known to promote beta (beta) amyloid deposition in the cortex, and preliminary evidence suggests that RT may be associated with this process. However, it is unknown whether beta-amyloid accumulation contributes to treatment neurotoxicity. In this pilot study, we assessed neuropsychological functions and beta-amyloid retention using 18F florbetaben (FBB) PET in a subset of brain tumor patients who participated in our study of APOE polymorphisms and cognitive functions. Twenty glioma patients treated with conformal RT +/- chemotherapy participated in the study: 6 were APOE epsilon-4 carriers and 14 were non-epsilon-4 carriers. Patients completed a neuropsychological re-evaluation (mean time interval = 5 years, SD = 0.83) and brain MRI and FBB PET scans. Wilcoxon signed-rank test comparisons between prior and current neuropsychological assessments showed a significant decline in attention (Brief Test of Attention, p = 0.018), and a near significant decline in verbal learning (Hopkins Verbal learning Test-Learning, p = 0.07). Comparisons by APOE status showed significant differences over time in attention/working memory (WAIS-III digits forward, p = 0.028 and digits backward, p = 0.032), with a decline among APOE epsilon-4 carriers. There were no significant differences in any of the FBB PET analyses between APOE epsilon-4 carriers and non-epsilon-4 carriers. The findings suggest that glioma patients may experience worsening in attention and executive functions several years after treatment, and that the APOE epsilon-4 allele may modulate cognitive decline, but independent of increased beta-amyloid deposition. PMID- 29168084 TI - Bioinformatic analysis of gene expression and methylation regulation in glioblastoma. AB - Different gene expression and methylation profiles are identified in glioblastoma (GBM). To screen the differentially expressed genes affected by DNA methylation modification and further investigate their prognostic values for GBMs. We included The Cancer Genome Atlas (TCGA) RNA sequencing (676) and DNA methylation (Illumina Human Methylation 450K; 657) databases to detect the gene expression and methylation profiles. Chinese Glioma Genome Atlas (CGGA) RNA sequencing database and TCGA DNA methylation (Illumina Human Methylation 27K; 283) was included for validation. Gene expression and DNA methylation statues were identified using principal components analysis (PCA). A total of 3365 differentially expressed genes were identified. Among them, 2940 genes showed low methylation and high expression, while 425 genes showed high methylation and low expression in GBMs. An eight-gene (C9orf64, OSMR, MDK, MARVELD1, PTRF, MYD88, BIRC3, RPP25) signature was established to divide GBM patients into two groups based on the cut-off point (27.24). The high risk group had shorter overall survival (OS) than low risk group (median OS 15.77 vs. 10.61 months; P = 0.0002). Moreover, the different clinical and molecular features were shown between two groups. These findings could be validated in additional datasets. The differentially expressed genes affected by DNA methylation modification were detected. Our results showed that the eight-gene signature has independently prognostic value for GBM patients.

AB - Human papillomavirus infection (HPV) is the most common sexually transmitted infection among United States Military Servicemembers, and present in the majority of cervical cancers. Many of these infections are preventable, but HPV immunization is not mandatory during military service. The objective of this study was to examine the prevalence of vaccine-preventable cervical disease among women enrolled in the San Antonio Military Health System. This is a retrospective cross-sectional study of Pap smear results and HPV genotyping data among Military Servicewomen and beneficiaries. Simple descriptive statistics and logistic regression were used to assess the association between demographics, cervical pathology and high-risk HPV (hrHPV) infection. Pap smears were obtained by 16.9% of women and cervical pathology was present in 28.8% of samples. Compared to the 25-34 year group, 35-44 year-olds were more likely to have an abnormal Pap smear (OR 1.25, CI 1.05-1.50). Of the samples tested, 10.5% were positive for hrHPV. Adjusted multivariable analysis revealed that hrHPV infection was more likely among the 23-34 year group when compared to 35-44 (OR 0.50, CI 0.38-0.67), 45-54 (0.40. CI 0.28-0.59) and 55-65 year groups (0.46, CI 0.30-0.71). Active Duty Servicewomen were more likely to test positive for hrHPV when compared to Active Duty Family Members (OR 0.59, CI 0.45-0.79) and Retiree Family Members (OR 0.59, CI 0.41-0.83). Younger women and Active Duty Servicewomen are significantly more likely to have cervical infection with hrHPV. Future studies should assess the cost-effectiveness of mandatory HPV immunization for military members.

AB - Both autism spectrum disorder (ASD) and schizophrenia are often characterized as disorders of white matter integrity. Multimodal investigations have reported elevated metabolic rates, cerebral perfusion and basal activity in various white matter regions in schizophrenia, but none of these functions has previously been studied in ASD. We used 18fluorodeoxyglucose positron emission tomography to compare white matter metabolic rates in subjects with ASD (n = 25) to those with schizophrenia (n = 41) and healthy controls (n = 55) across a wide range of stereotaxically placed regions-of-interest. Both subjects with ASD and schizophrenia showed increased metabolic rates across the white matter regions assessed, including internal capsule, corpus callosum, and white matter in the frontal and temporal lobes. These increases were more pronounced, more widespread and more asymmetrical in subjects with ASD than in those with schizophrenia. The highest metabolic increases in both disorders were seen in the prefrontal white matter and anterior limb of the internal capsule. Compared to normal controls, differences in gray matter metabolism were less prominent and differences in adjacent white matter metabolism were more prominent in subjects with ASD than in those with schizophrenia. Autism spectrum disorder and schizophrenia are associated with heightened metabolic activity throughout the white matter. Unlike in the gray matter, the vector of white matter metabolic abnormalities appears to be similar in ASD and schizophrenia, may reflect inefficient functional connectivity with compensatory hypermetabolism, and may be a common feature of neurodevelopmental disorders. PMID- 29168087 TI - Mediating Parent Learning to Promote Social Communication for Toddlers with Autism: Effects from a Randomized Controlled Trial. AB - A randomized controlled trial was conducted to evaluate effects of the Joint Attention Mediated Learning (JAML) intervention. Toddlers with autism spectrum disorders (ASD) aged 16-30 months (n = 144) were randomized to intervention and community control conditions. Parents, who participated in 32 weekly home-based sessions, followed a mediated learning process to target preverbal social communication outcomes (social visual synchrony, reciprocity, and responding and initiating forms of joint attention) throughout daily interactions. The analysis found post-intervention effects for all outcomes, with all except initiating joint attention sustaining 6 months post-intervention. Findings support the value of very early intervention targeting explicitly social functions of preverbal communication and of promoting active engagement in the learning process for both toddlers and parents. PMID- 29168088 TI - What Are You Doing With That Object? Comparing the Neural Responses of Action Understanding in Adolescents With and Without Autism. AB - Understanding another's actions, including what they are doing and why they are doing it, can be difficult for individuals with autism spectrum disorder (ASD). This understanding is supported by the action observation (AON) and mentalizing (MZN) networks, as well as the superior temporal sulcus. We examined these areas in children with ASD and typically developing controls by having participants view eating and placing actions performed in conventional and unconventional ways while functional magnetic resonance images were collected. We found an effect of action-type, but not conventionality, in both groups, and a between groups difference only when viewing conventional eating actions. Findings suggest there are not global AON/MZN deficits in ASD, and observing unconventional actions may not spontaneously activate the MZN. PMID- 29168089 TI - Brief Report: Investigating Relations Between Self-Concept and Performance in Reading and Math for School-Aged Children and Adolescents with Autism Spectrum Disorder. AB - A typically developing student's perceptions of his or her own capabilities (academic self-concept), is predictive of later academic achievement. However, little is known about academic self-concept in youth with autism spectrum disorder (ASD). To understand whether students math self-concept and reading self concept predicted their performance, 44 school-aged children and adolescents with ASD and 36 age-matched individuals with typical development (TYP) rated their perceived math and reading abilities and were administered standardized achievement measures. Results showed self-concept was predictive of performance in math and reading in the TYP group. For youth with ASD, there was agreement between self-concept and performance only in math. These findings suggest that educators should be cautious when interpreting the self-assessments of reading ability in students with ASD. PMID- 29168090 TI - Using Virtual Interactive Training Agents (ViTA) with Adults with Autism and Other Developmental Disabilities. AB - Conversational virtual human (VH) agents are increasingly used to support role play experiential learning. This project examined whether a Virtual Interactive Training Agent (ViTA) system would improve job interviewing skills in individuals with autism and developmental disabilities (N = 32). A linear mixed model was employed to evaluate adjusted least square mean differences of means scores on the Marino Interview Assessment Scale (MIAS) across different time points. The mean score of MIAS over all questions increased between the first ViTA session and the final face-to-face interview. Participants developed the ability to identify strengths, self-promote, self-advocate, answer situational questions, and respond to behavioral/social questions as measured by multiple evaluations using the MIAS. PMID- 29168091 TI - Postural and Cortical Responses Following Visual Occlusion in Adults With and Without ASD. AB - Autism is associated with differences in sensory processing and motor coordination. Evidence from electroencephalography suggests individual perturbation evoked response (PER) components represent specific aspects of postural disturbance processing; P1 reflects the detection and N1 reflects the evaluation of postural instability. Despite the importance of these cortical responses to postural control, PERs to a perturbation in adults with autism spectrum disorder (ASD) have yet to be reported. The aim was to compare PERs to visual perturbation under varied postural stability conditions in adults with and without ASD. This study is the first to report that while the assessment of postural set is intact, adults with ASD use more cortical resources to integrate and interpret visual perturbations for postural control.

AB - In the present study, five important binary fingerprinting techniques were used to model novel flavones for the selective inhibition of Tankyrase I. From the fingerprints used: the fingerprint atom pairs resulted in a statistically significant 2D QSAR model using a kernel-based partial least square regression method. This model indicates that the presence of electron-donating groups positively contributes to activity, whereas the presence of electron withdrawing groups negatively contributes to activity. This model could be used to develop more potent as well as selective analogues for the inhibition of Tankyrase I. Schematic representation of 2D QSAR work flow. PMID- 29168092 TI - Propofol Prevents Oxidative Stress by Decreasing the Ischemic Accumulation of Succinate in Focal Cerebral Ischemia-Reperfusion Injury. AB - Oxidative stress caused by mitochondrial dysfunction during reperfusion is a key pathogenic mechanism in cerebral ischemia-reperfusion (IR) injury. Propofol (2,6 diisopropylphenol) has been proven to attenuate mitochondrial dysfunction and reperfusion injury. The current study reveals that propofol decreases oxidative stress injury by preventing succinate accumulation in focal cerebral IR injury. We evaluated whether propofol could attenuate ischemic accumulation of succinate in transient middle cerebral artery occlusion in vivo. By isolating mitochondria from cortical tissue, we also examined the in vitro effects of propofol on succinate dehydrogenase (SDH) activity and various mitochondrial bioenergetic parameters related to oxidative stress injury, such as the production of reactive oxidative species, membrane potential, Ca2+-induced mitochondrial swelling, and morphology via electron microscopy. Propofol significantly decreased the ischemic accumulation of succinate by inhibiting SDH activity and inhibited the oxidation of succinate in mitochondria. Propofol can decrease membrane potential in normal mitochondria but not in ischemic mitochondria. Propofol prevents Ca2+-induced mitochondrial swelling and ultrastructural changes to mitochondria. The protective effect of propofol appears to act, at least in part, by limiting oxidative stress injury by preventing the ischemic accumulation of succinate. PMID- 29168094 TI - What Money Can't Buy: Different Patterns in Decision Making About Sex and Money Predict Past Sexual Coercion Perpetration. AB - Self-reported impulsivity has been found to predict the perpetration of sexual coercion in both sexual offenders and male college students. Impulsivity can be conceptualized as a generalized lack of self-control (i.e., general perspective) or as a multifaceted construct that can vary from one context to the other (i.e., domain-specific perspective). Delay discounting, the tendency to prefer sooner smaller rewards over larger delayed rewards, is a measure of impulsive decision making. Recent sexual adaptations of delay discounting tasks can be used to test domain-specific assumptions. The present study used the UPPS-P impulsivity questionnaire, a standard money discounting task, and a sexual discounting task to predict past use of sexual coercion in a sample of 98 male college students. Results indicated that higher negative urgency scores, less impulsive money discounting, and more impulsive sexual discounting all predicted sexual coercion. Consistent with previous studies, sexuality was discounted more steeply than money by both perpetrators and non-perpetrators of sexual coercion, but this difference was twice as large in perpetrators compared to non-perpetrators. Our study identified three different predictors of sexual coercion in male college students: a broad tendency to act rashly under negative emotions, a specific difficulty to postpone sexual gratification, and a pattern of optimal non-sexual decision making. Results highlight the importance of using multiple measures, including sexuality-specific measures, to get a clear portrait of the links between impulsivity and sexual coercion.

AB - BACKGROUND: Existing prognostic systems were not developed using only objective variables available preoperatively, and therefore do not provide ideal prognostication for patients undergoing hepatectomy for hepatocellular carcinoma (HCC). We aimed to develop a preoperative prognostic model using objective variables involving two parameters: 18F-fluorodeoxyglucose-positron emission tomography (18F-FDG-PET) and the albumin-bilirubin (ALBI) grade. METHODS: This study included 207 consecutive patients with solitary HCC who underwent 18F-FDG PET prior to hepatectomy. The tumor to non-tumor maximum standardized uptake value ratio (TNR) was used as an 18F-FDG PET imaging parameter. RESULTS: The 5 year overall survival (OS) and disease-free survival (DFS) rates were 58.6% and 28.8%, respectively. Multivariate analysis of OS identified TNR >= 2 (hazard ratio [HR] 1.743, 95% confidence interval [CI] 1.114-2.648, p = 0.016) and ALBI grade 2 (HR 1.966, 95% CI 1.349-2.884, p < 0.001) as the only significant prognostic factors; tumor diameter and tumor markers were not significant. Patients were divided into low- (TNR < 2 and ALBI grade 1), intermediate- (TNR < 2 and ALBI grade 2, or TNR >= 2 and ALBI grade 1), and high-risk (TNR >= 2 and ALBI grade 2) groups, which differed significantly in terms of survival (5-year OS: 75.7, 49.6, and 27.3%, respectively, p < 0.001; 5-year DFS: 37.0, 24.9, and 13.6%, respectively, p < 0.001). Compared with other staging systems, our model had the best discriminatory ability (corrected Akaike information criteria 1054.8, p < 0.001) and homogeneity (likelihood ratio Chi square value 27.6, p < 0.001). CONCLUSION: A preoperative prognostic model incorporating 18F-FDG-PET imaging with the ALBI grade may be useful for estimating the prognosis of selected patients with solitary HCC.

PMID- 29168099 TI - Benchmarking the American Society of Breast Surgeon Member Performance for More Than a Million Quality Measure-Patient Encounters. AB - BACKGROUND: Nine breast cancer quality measures (QM) were selected by the American Society of Breast Surgeons (ASBrS) for the Centers for Medicare and Medicaid Services (CMS) Quality Payment Programs (QPP) and other performance improvement programs. We report member performance. STUDY DESIGN: Surgeons entered QM data into an electronic registry. For each QM, aggregate "performance met" (PM) was reported (median, range and percentiles) and benchmarks (target goals) were calculated by CMS methodology, specifically, the Achievable Benchmark of CareTM (ABC) method. RESULTS: A total of 1,286,011 QM encounters were captured from 2011-2015. For 7 QM, first and last PM rates were as follows: (1) needle biopsy (95.8, 98.5%), (2) specimen imaging (97.9, 98.8%), (3) specimen orientation (98.5, 98.3%), (4) sentinel node use (95.1, 93.4%), (5) antibiotic selection (98.0, 99.4%), (6) antibiotic duration (99.0, 99.8%), and (7) no surgical site infection (98.8, 98.9%); all p values < 0.001 for trends. Variability and reasons for noncompliance by surgeon for each QM were identified. The CMS-calculated target goals (ABCTM benchmarks) for PM for 6 QM were 100%, suggesting that not meeting performance is a "never should occur" event. CONCLUSIONS: Surgeons self-reported a large number of specialty-specific patient measure encounters into a registry for self-assessment and participation in QPP. Despite high levels of performance demonstrated initially in 2011 with minimal subsequent change, the ASBrS concluded "perfect" performance was not a realistic goal for QPP. Thus, after review of our normative performance data, the ASBrS recommended different benchmarks than CMS for each QM.

AB - INTRODUCTION: Amputation for localized extremity sarcoma (ES), once the primary therapy, is now rarely performed. We reviewed our experience to determine why patients with sarcoma still undergo immediate or delayed amputation, identify differences based on amputation timing, and evaluate outcomes. METHODS: Records of patients with primary, nonmetastatic ES who underwent amputation at our institution from 2001 to 2011 were reviewed. Univariate analysis was performed, and survival outcomes were calculated. RESULTS: We categorized 54 patients into three cohorts: primary amputation (A1, n = 18, 33%), secondary amputation after prior limb-sparing surgery (A2, n = 22, 41%), and hand and foot sarcomas (HF, n = 14, 26%). Median age at amputation was 54 years (range 18-88 years). Common indications for amputation (> 40%) were loss of function, bone involvement, multiple compartment involvement, and large tumor size (A1); proximal location, joint involvement, neurovascular compromise, multiple compartment involvement, multifocal or fungating tumor, loss of function, and large tumor size (A2); and joint involvement and prior unplanned surgery (HF). There was no difference in disease-specific survival (DSS) (p = 0.19) or metastasis-free survival (MFS) (p = 0.31) between early (A1) and delayed (A2) amputation. Compared with cohorts A1/A2, HF patients had longer overall survival (OS) (p = 0.04). CONCLUSIONS: Indications for amputation for extremity sarcoma vary between those who undergo primary amputation, delayed amputation, and amputation for hand or foot sarcoma. Amputations chosen judiciously are associated with excellent disease control and survival. For patients who ultimately need amputation, timing (early vs. delayed) does not affect survival. PMID- 29168104 TI - Safe use of infliximab for the treatment of severe perianal Crohn's disease after diagnosis and treatment of lymphoma. AB - Inflammatory bowel disease is associated with an increased likelihood of developing lymphoma. However, it is still controversial if this risk may be attributed to the disease itself or rather represents an effect of immunosuppressive treatment. Although tumor necrosis factor alpha (TNFalpha) is a key cytokine for cancer immunosurveillance, the potential relationship between anti-TNFalpha agents and the pathogenesis of lymphoproliferative disorders remains unclear. Here, we describe the case of a patient with severe perianal Crohn's disease, treated with infliximab monotherapy, whose unusual presentation with acute groin pain required surgical intervention and led to the diagnosis of diffuse large B-cell lymphoma. However, 10 months after this episode, treatment with infliximab was restarted because the patient continued with refractory and disabling perianal disease. Currently, with a follow-up of 36 months, under infliximab 10 mg/kg every 4 weeks, he maintains mild perianal Crohn's disease and persists in sustained clinical and imaging remission of the lymphoproliferative disorder. PMID- 29168105 TI - Evaluation of four commercial natural products for repellency and toxicity against the lone star tick, Amblyomma americanum (Acari: Ixodidae). AB - Lone star ticks are aggressive ectoparasites of domestic and wild animals, as well as humans. These ticks can transmit many pathogens that cause disease including Erhlichia and tularemia. Common compounds used for personal protection and area sprays are N-diethyl-3-methyl benzamide (DEET) and permethrin, but public concern over personal and environmental safety require the development of new, safer products. In the current study, four commercially available products (Wondercide, Essentria IC3, Vet's Best, and Mosquito Barrier) were tested for both repellent and toxic effects against lone star tick nymphs and adults. Overall, all four products were more effective against nymphs than against adults. Wondercide and Essentria IC3 were as toxic to nymphs as permethrin at concentrations of 3.13% and higher, and as repellent as DEET at all concentrations. Nymphs were also repelled by Mosquito Barrier and Vet's Best, but these products had about half or less of the repellent effects of Wondercide and Essentria IC3 at most of the concentrations. Adult ticks were repelled similarly by all products at all tested concentrations, but at lower levels than nymphs. Toxicity of the four tested products on adults was similar at concentrations of 12.5% and below, less than half of what was observed with permethrin with declining effectiveness as concentrations decreased. Overall, these four products may offer a natural way to repel lone star ticks, but further field testing is needed to determine rates of application and residual activity.

The participants were 15 people with depression and/or anxiety symptoms. The participants followed an exercise program. Depression and anxiety symptoms were assessed with validated questionnaires. An exercise program can be used as a treatment option for people with depression and/or anxiety with good results in comparison with TCBGT. PMID- 29168107 TI - Predictive factors of trastuzumab-based chemotherapy in HER2 positive advanced gastric cancer: a single-center prospective observational study. AB - PURPOSE: Trastuzumab plus chemotherapy is an effective therapy in HER2 positive advanced gastric cancer (AGC). However, the clinicopathologic factors that predict the outcome of routine trastuzumab therapy remain unclear. METHODS: The outcome and safety profile of trastuzumab therapy in untreated HER2 positive AGC was evaluated in this prospective observational study. Clinical and pathological data including demographics, treatment profiles, expression level of HER2 were analyzed to identify predictive factors of trastuzumab-based first-line therapy for their progression-free survival (PFS). RESULTS: Overall, 107 patients were eligible. The median number of treatment cycles was 9 (range 1-44), the median PFS and median overall survival (OS) were 7.7 months (95% CI 6.5-8.9) and 16.0 months (95% CI 13.2-18.8), respectively. The confirmed response rate was 58.9%, and the disease control rate was 82.2%. Patients with liver metastasis (HR 1.616) and poor performance status (PS, HR 2.518) were independently associated with a worse PFS, while the other clinicopathological factors including demographics, treatment profiles and some other clinical characteristics did not predict the survival. CONCLUSIONS: In routine clinical practice, the addition of trastuzumab to chemotherapy was effective and safe in real-world setting in Chinese patients with HER2 positive AGC, regardless of most of the clinicopathological factors. Further studies are needed to improve the prognosis of HER2 positive patients with liver metastasis or poor PS. Trial Registration clinicaltrials.gov Identifier: NCT03024450. PMID- 29168108 TI - The malaris muscle: its morphological significance for sustaining the intraorbital structures. AB - The orbicularis oculi muscle, an important mimetic muscle, was investigated to ascertain its anatomical relation to facial aging-especially its orbital part (Oo). Previous studies of the distinct muscle bundles frequently found inferior to the Oo have provided various definitions, including that of the malaris muscle. This study aimed to examine these muscle bundles and clarify their function in facial aging. Twelve heads of Japanese cadavers (average age: 82.5 years old) were dissected to observe the muscles, focusing in particular on those in the periorbital region. Six specimens were further dissected from the inner surfaces to examine the patterns of facial nerve branches under the operating microscope. Histological examinations of two head halves were carried out to investigate the relationship between the muscle bundles and the intraorbital structures. Muscle bundles consisting of lateral, medial, and U-shaped suspending bundles were observed in the region inferior to the Oo. Lateral and suspending bundles were found in all specimens, while the medial bundles were noted in only 9 of 22 specimens. Some branches of the facial nerve penetrated through the lateral, medial, and suspending bundles. The relationship between the suspending bundles and the protruding orbital fat was assessed. The muscle bundles found in this study were regarded as the malaris muscle-a transitional muscle between the superficial and deep facial layers. The suspending bundle may play a role in sustaining the intraorbital structures. PMID- 29168109 TI - A Case of Glomangiopericytoma at the Nasal Septum. AB - Glomangiopericytoma (GPC) is a rare sinonasal perivascular tumor that accounts for < 0.5-1% of all sinonasal tumors. GPC is categorized as a low-grade neoplasm with borderline malignancy and a tendency of local recurrence. GPC is a rare mesenchymal neoplasm characterized by the perivascular proliferation of tumor cells, and it requires being distinguished from solitary fibrous tumors. Here, we report a case of GPC in a 68-year-old male patient who presented at the emergency room of our hospital with a complaint of sudden epistaxis. A small, reddish, protruding tumor was observed on the right nasal septum. A biopsy revealed a possible perivascular tumor such as a GPC or solitary fibrous tumor. Thus, we performed complete resection with endoscopic surgery. The size of the resected tumor was 12 * 5 mm, and it showed a uniform proliferation of oval-to-short spindle-shaped cells with slightly branching vascular structures. The tumor cells showed minimal cytologic atypia and there were an average of 3 mitoses in 10 high power fields. Necrosis was not observed. The tumor cells showed strong and diffuse nuclear immunostaining with beta catenin and were negative with STAT6, CD34 and bcl-2. The MIB-1 labeling index was approximately 5%. Genetic testing revealed CTNNB1 mutation (p.S33C). Thus, a diagnosis of low grade GPC was made on the biopsy and the patient could be successfully treated with endoscopic resection. PMID- 29168110 TI - Symptom covariance accounts for behavioral approach associations across impulse control disorders. AB - Behavioral approach system (BAS) dysfunction has been identified as a correlate of and a potential mechanism for attention-deficit/hyperactivity disorder (ADHD) and comorbid disorders. This study examined the role of symptom covariation in the relations among BAS dysfunction, ADHD symptoms, and comorbid impulsive personality disorder features. Undergraduates (N = 207) completed measures of BAS functioning, ADHD symptoms, and borderline and antisocial personality disorder symptoms, and associated features (i.e., relational aggression). Hierarchical regression suggested that age, impulsive ADHD symptoms, and relational aggression were associated with BAS functioning. Adding other ADHD symptom dimensions (inattention, hyperactivity) and antisocial and borderline scores to the model did not increase variance accounted for beyond that accounted for by ADHD impulsivity scores. Results highlight a role of symptom covariance in the previously demonstrated relation between BAS, impulsive presentations of ADHD, and comorbid impulsive personality pathology. Implications for etiological models of ADHD and its co-occurrence with other disorders are discussed. PMID- 29168111 TI - Bariatric Surgery and Time to Total Joint Arthroplasty: Does It Affect Readmission and Complication Rates? AB - BACKGROUND: Bariatric surgery is frequently recommended prior to total joint arthroplasty (TJA) for morbidly obese patients with end-stage arthropathy. Current published data on the efficacy of bariatric surgery for preoperative medical optimization has yielded mixed results, and the effect of time from bariatric surgery to TJA on the preoperative risk profile is not well defined. Our study evaluated the effect of time from bariatric surgery to TJA on 90-day complication and readmission rates. METHODS: We utilized the Healthcare Cost and Utilization Project (HCUP) California State Inpatient Database (SID) to identify patients who underwent TJA following bariatric surgery between 2007 and 2011. Primary endpoints were 90-day complication rates and all-cause 90-day readmission rates following TJA. RESULTS: We identified 330 cases of bariatric surgery followed by total hip arthroplasty (THA) and 1017 cases followed by total knee arthroplasty (TKA). There were no significant demographic differences among patients who underwent TJA greater than or less than 6 months after bariatric surgery. Patients undergoing THA more than 6 months after bariatric surgery were significantly less likely to be readmitted within 90 days for any cause. There was no association between time from bariatric surgery to THA or TKA and 90-day complications. DISCUSSION: Delaying THA at least 6 months after bariatric surgery may help reduce the rate of 90-day readmissions in this high-risk patient population. Arthroplasty surgeons recommending bariatric surgery as preoperative risk modification should consider the patient's overall nutritional status, medical comorbidities, and overall response to surgery prior to booking for TJA. PMID- 29168112 TI - Treatment Patterns and Outcomes in Patients with KRAS Wild-Type Metastatic Colorectal Cancer Treated in First Line with Bevacizumab- or Cetuximab-Containing Regimens. AB - PURPOSE: Patients with Kirsten rat sarcoma viral oncogene wild-type (KRAS WT) metastatic colorectal cancer (mCRC) treated in first line with bevacizumab (B) or cetuximab (C) plus standard chemo backbones had comparable outcomes in phase III Cancer and Leukemia Group B (CALGB) 80405. We examined comparative effectiveness of B and C regimens in real-world community settings. METHODS: This retrospective study examined progression-free survival (PFS) and OS in a US community sample of KRAS WT mCRC patients treated with first-line B (n = 254) or C (n = 146) regimens. Medical records from the Vector Oncology Data Warehouse were used. Disease progression was determined from patient charts. OS was measured from the start of first-line treatment until death. RESULTS: There were no significant difference in either PFS or OS respectively between B-treated compared to C treated patients (HR = 1.324, 95% CI 0.901, 1.947; HR = 1.080, 95% CI 0.721, 1.617). More B patients received oxaliplatin backbones (74.8 vs. 36.3%), and more C patients received irinotecan backbones (51.4 vs. 20.1%), ps < 0.001. Multivariate survival analyses showed a significant difference indicating a greater risk for death among C-treated patients with right-sided tumors vs. left sided tumors (HR = 2.263, 95% CI 1.394, 3.673, p = 0.0009), but not for B-treated patients (HR = 1.209, 95% CI 0.825, 1.771, p = 0.3297). CONCLUSIONS: Consistent with CALGB 80405, median PFS and OS for these community oncology KRAS WT mCRC patients treated with first-line B or C regimens did not differ significantly. PMID- 29168113 TI - Dynamics of Bone Marrow VSELs and HSCs in Response to Treatment with Gonadotropin and Steroid Hormones, during Pregnancy and Evidence to Support Their Asymmetric/Symmetric Cell Divisions. AB - Gender plays an important role in the incidence of hematological malignancies and recently hematopoietic stem cells (HSCs) were found to proliferate more in females that gets further augmented during pregnancy. It was suggested that since basal numbers of HSCs remain the same in both sexes, possibly HSCs in females undergo increased self-renewal and apoptosis. Then how is self-renewal of stem cells regulated in males? More important, do HSCs undergo asymmetric cell divisions (ACD) or a more primitive population of pluripotent, very small embryonic-like stem cells (VSELs) undergo ACD to self-renew and specify into HSCs? Lot more clarity is required on the bone marrow stem cells biology. Present study was undertaken to evaluate whether similar dimorphism reported for HSCs also exists among VSELs. Bone marrow VSELs and HSCs were studied in bilaterally ovariectomized and castrated mice by flow cytometry after treating with gonadotropin (FSH) and sex steroid (estrogen & progesterone) hormones and during pregnancy. Differential expression of pluripotent (Oct-4A, Sox2, Nanog) and differentiation (Oct-4, Sca1, c-Kit, Ikaros) specific transcripts was studied. Basal BrdU uptake was more in both VSELs (p < 0.01) and HSCs (p < 0.05) in female bone marrow. FSH exerted a more profound effect compared to estradiol in both the sexes. Flow cytometry results showed ten-fold increase in spleen VSELs by mid gestation associated with approximately two-fold increase in HSCs. These results point to a novel yet unreported role of spleen VSELs during pregnancy. Furthermore, VSELs underwent ACD to self-renew and give rise to slightly bigger HSCs based on unequal expression of NUMB, CD45 and OCT-4.

Previous studies on first language (L1) lexical processing have observed that ambiguous words are recognized faster and more accurately than unambiguous words on lexical decision tasks. In this research, L1 and L2 speakers of English were asked whether a letter string on a computer screen was an English word or not. An ambiguity advantage was found for both groups and greater ambiguity effects were found for the non-native speaker group when compared to the native speaker group. The findings imply that the larger ambiguity advantage for L2 processing is due to their slower response time in producing adequate feedback activation from the semantic level to the orthographic level.

AB - PURPOSE: Increased parathyroid hormone (PTH) is commonly associated with obesity, and its role in the pathogenesis of obesity-related glucometabolic abnormalities is uncertain. We aimed to explore the relationships of PTH with glucose/insulin homeostasis parameters before and after bariatric surgery-induced weight loss, and whether they depend or not on 25-hydroxyvitamin D (25OHD) status. METHODS: We included 42 subjects (27 women, aged 40 +/- 5 years, BMI 48.5 +/- 7.3 kg/m2) without diabetes, chronic kidney disease, or hyperparathyroidism undergoing sleeve gastrectomy. The following parameters were evaluated before and 6 months after surgery: circulating levels of PTH, calcium, phosphorus, 25OHD, leptin, insulin growth factor (IGF)-1; 75-g oral glucose tolerance test to derive measures of insulin sensitivity (ISI) and secretion (Stumvoll index); dual-energy X-ray absorptiometry to assess fat distribution and bone mineral density. RESULTS: Weight loss was accompanied by significant reduction of PTH levels (77.9 +/- 19.1 vs. 60.5 +/- 13.4 pg/ml; p = 0.005), without concomitant modification of 25OHD status. Both baseline PTH and its postoperative percent change resulted associated, with baseline fat mass (beta = 0.615, p = 0.003) and its concurrent postoperative reduction (r = 0.419; p = 0.006), but neither with glucose homeostasis parameters nor their respective variations after weight loss. Interestingly, leptin reduction after weight loss was independently related to PTH change (beta = 0.396, p = 0.015) and IGF-1 levels (beta = 0.176, p = 0.059). CONCLUSIONS: Circulating PTH decreases with fat mass reduction independent of 25OHD status, but it is not associated with improvement of insulin resistance and related metabolic parameters. Leptin and PTH may mediate the cross-talk between adipose tissue and parathyroid glands, which possibly contributes to bone adaptation to excess body weight.

AB - In this paper, we analyze how a political blog author (Spanish Alejo Vidal Quadras) establishes the reference to self and other in his blog entries. We furthermore look into how the commentators to this blog react and establish reference to self and other in the digital public sphere. More concretely, we show that they not only take up the references established by the main blog author but also create new references. These allow, on the one hand, for profiling themselves as part of a group and, on the other hand, identifying their interlocutor among the variety of possible interlocutors in the digital public sphere. By addressing different interlocutors, the commentators turn the comments section into a dialogic space, a dimension that is lacking in the main blog entries. However, the fact that they almost invariably identify interlocutors other than Vidal-Quadras but address Vidal-Quadras without explicitly identifying him, shows that Vidal-Quadras remains the main ratified interlocutor in view of his ownership of the blog. This paper shows then how participants in the digital public sphere create a complex relationship of self and other reference in political blogs. PMID- 29168117 TI - Anaphoric Strategies Across Language Modalities: A Comparison Between Catalan and Catalan Sign Language (LSC). AB - The goal of this paper is to compare the different anaphoric strategies that Catalan and Catalan Sign Language (LSC) use by means of a parallel corpus. In particular, our comparison is focused in an examination of the uses of overt subject pronouns in Catalan and how these uses are rendered in a language that exploits the visual-manual modality, such as LSC. As far as we know, this is one of the first studies to compare reference-tracking devices in a spoken and a signed language by means of a parallel corpus and incorporating both a descriptive and a theoretical perspective. All instances of overt pronouns in Catalan were analyzed and most of the data can be accounted with three factors: topic change, focus and contrast. As for LSC, the use of pronouns is rare and only few instances were found. Instead, other anaphoric strategies are used: while topic change and focus are primarily encoded with bare nouns, the expression of contrast relies on modality-specific features. PMID- 29168118 TI - Ion-protein interactions of a potassium ion channel studied by attenuated total reflection Fourier transform infrared spectroscopy. AB - An understanding of ion-protein interactions is key to a better understanding of the molecular mechanisms of proteins, such as enzymes, ion channels, and ion pumps. A potassium ion channel, KcsA, has been extensively studied in terms of ion selectivity. Alkali metal cations in the selectivity filter were visualized by X-ray crystallography. Infrared spectroscopy has an intrinsically higher structural sensitivity due to frequency changes in molecular vibrations interacting with different ions. In this review article, I attempt to summarize ion-exchange-induced differences in Fourier transform infrared spectroscopy, as applied to KcsA, to explain how this method can be utilized to study ion-protein interactions in the KcsA selectivity filter. A band at 1680 cm-1 in the amide I region would be a marker band for the ion occupancy of K+, Rb+, and Cs+ in the filter. The band at 1627 cm-1 observed in both Na+ and Li+ conditions suggests that the selectivity filter similarly interacts with these ions. In addition to the structural information, the results show that the titration of K+ ions provides quantitative information on the ion affinity of the selectivity filter. PMID- 29168119 TI - Clinical and biological significance of a - 73A > C variation in the CDH1 promoter of patients with sporadic gastric carcinoma. AB - BACKGROUND: CDH1 germline mutations lead to hereditary diffuse gastric carcinomas. However, it is unclear whether genetic variations in the CDH1 promoter affect the progression of sporadic gastric carcinomas (SGCs). METHODS: SGC patients in two independent cohorts with follow-up data were enrolled. The CDH1 genotypes, including the - 73A > C polymorphism (rs28372783), were determined by PCR sequencing. The CDH1 promoter activity was determined using reporter assays. SNAIL bound to CDH1 alleles was determined by chromatin immunoprecipitation primer extension PCR. CDH1 DNA methylation was determined by bisulfite-based PCR analyses. RESULTS: Kaplan-Meier analyses showed that the overall survival (OS) of the - 73C/C patients was significantly longer than that of the - 73A/C or - 73A/A patients in a Chinese cohort [n = 526; hazard ratio 0.68 (95% CI 0.47-1.00)], which was validated in an independent Korea cohort [n = 215; hazard ratio 0.49 (95% CI 0.26-0.94)]. Moreover, the transcription activity of the - 73C alleles was significantly higher than that of the - 73A alleles in vitro and in vivo. The ratio of SNAIL recruited to the promoter regions of the - 73C and - 73A alleles was 1:10, indicating a strong influence of this polymorphism on the recruitment of SNAIL to the flanking E-box. The prevalence of DNA methylation of the CpG island and shore within the promoter of the - 73C allele was much less than that of the - 73A allele in both gastric tissues and cancer cell lines. CONCLUSION: The - 73A > C variation may lead to differences in the overall survival of SGC patients and allele-specific repressions of CDH1. PMID- 29168121 TI - Paradigm changes in freshwater aquaculture practices in China: Moving towards achieving environmental integrity and sustainability. AB - Contribution of fisheries and aquaculture to global food security is linked to increased fish consumption. Projections indicate that an additional 30-40 million tonnes of fish will be required by 2030. China leads global aquaculture production accounting for 60% in volume and 45% in value. Many changes in the Chinese aquaculture sector are occurring to strive towards attaining environmental integrity and prudent use of resources. We focus on changes introduced in freshwater aquaculture developments in China, the main source of food fish supplies. We bring forth evidence in support of the contention that Chinese freshwater aquaculture sector has introduced major paradigm changes such as prohibition of fertilisation in large water bodies, introduction of stringent standards on nutrients in effluent and encouragement of practices that strip nutrients among others, which will facilitate long-term sustainability of the sector. PMID- 29168120 TI - The 8th edition of the American Joint Committee on Cancer tumor-node-metastasis staging system for gastric cancer is superior to the 7th edition: results from a Chinese mono-institutional study of 1663 patients. AB - BACKGROUND: We investigated the superiority of the 8th edition of the tumor-node metastasis (TNM) system for patients in China with gastric cancer. METHODS: The survival outcomes of 1663 patients with gastric cancer undergoing radical resection were analyzed. RESULTS: In the 8th edition system, homogeneous 5-year survival rates among different pathological TNM (pTNM) categories belonging to the same stage were observed. However, in the 7th edition system, the differences of 5-year survival rate among pTNM categories belonging to the same stage were observed in stages IIB (P = 0.010), IIIB (P = 0.004), and IIIC (P < 0.001). For patients in the pT1-3 (P < 0.001) and pT4a (P < 0.001) categories, there were significant differences in survival between patients in the pN3a and pN3b categories. Furthermore, partial cases (pT4bN0M0/T4aN2M0) of stage IIIB were downstaged to stage IIIA in the 8th edition system, and the 5-year survival rate of these patients was significantly better than that of patients in stage IIIB in the 8th edition system. Similarly, the 5-year survival rate of patients in p4bN2M0/T4aN3aM0 downstaged from stage IIIC to IIIB was significantly better than that of patients in stage IIIC. Compared with the 7th edition system, the 8th edition system had a higher likelihood ratio and linear trend chi-squared score and a smaller Akaike information criteria value. CONCLUSIONS: The 8th edition system is superior to the 7th edition system in terms of homogeneity, discriminatory ability, and monotonicity of gradients for Chinese patients with gastric cancer. PMID- 29168122 TI - Subtropical Interactions: Comparing Galling Insect and Host Plant Diversity in Southern Brazil and Florida. AB - Gall-inducing insects seem to have a diversity pattern distinct from the usual latitudinal decrease in species, with more species occurring in xeric environments instead. Many questions regarding galler diversity over geographical scales remain unanswered: for example, little is known about beta diversity, and the role super host plants play in local/regional richness. Our aim was to compare galling insect and host plant diversity in different biogeographical regions, but under similar environmental conditions. We sampled short stature coastal woodlands on sandy soils of the Atlantic coast in both USA (Florida) and Brazil (Rio Grande do Sul, RS), between 25 degrees and 30 degrees latitude. Little-used 200-m long trails were searched during 90 min for galls; there were four trails in USA and five in Brazil. Gall functional traits (galled plant organ, gall shape and colour) proportions were not different between Florida and RS. Local galling and host plant species richness also did not differ, and neither did regional galling diversity. The beta diversity pattern, however, was distinct: sites in Florida have more similar galling faunas than sites in RS. Common diversity patterns indicate common environmental biotic (plant diversity, vegetation structure) and abiotic (climate, soil) factors might be contributing to these similar responses. As Brazilian sites are in the Atlantic forest hotspot, a high galling insect beta diversity might be caused by a higher heterogeneity at larger scales-sample-based rarefaction curves were ascending for Brazil, but not for USA. Myrtaceans were super hosts in Brazil, but not in Florida, where oaks take up this role.

AB - INTRODUCTION: Hyperglycemia plays an important role in the pathogenesis of diabetic complications, as it increases protein glycation, as well as the progressive accumulation of advanced glycation end products (AGEs), which are complex structures that produce fluorescence. The glycation reaction raises the levels of protein carbonyl, N epsilon-(carboxymethyl)lysine (CML), and fructosamine and decreases the level of thiol groups. METHODS: In the present study, the antiglycation activity was determined by fluorescence intensity using the bovine serum albumin (BSA)/glucose, CML method, and the level of fructosamine. The oxidation of proteins was determined by the carbonyl protein content and thiol groups. RESULTS: The results show that the hexane extract of Acca sellowiana (FOH) at different concentrations (0.30-5 mg/ml) significantly inhibited the formation of AGEs in the BSA/glucose model during the 4 weeks of the study. FOH reduced the levels of fructosamine and CML. Our results showed a significant effect of FOH in the prevention of oxidative damage of proteins, as well as an effect on the oxidation of thiol groups and carbonyl proteins. CONCLUSION: The present study indicates that FOH is effective in inhibiting the glycation of proteins in vitro, so it can prevent or ameliorate the chronic conditions of diabetes associated with the formation of AGEs. PMID- 29168125 TI - Some Questions Pondered on Health and Humanities: Prospects, Opportunities and Challenges. PMID- 29168126 TI - Do alerting signals increase the size of the attentional focus? AB - Previous research has shown that the presentation of an auditory alerting signal before a visual target increases the interference from flanking distractors. Recently, it has been suggested that this increase in interference may be due to an expansion of the spatial focus of attention. In five experiments, this hypothesis was tested by using a probe technique dedicated to measuring variations in the size of the attentional focus: In the majority of trials, participants performed a letter discrimination task in which their attention was focused on a central target letter. In a randomly intermixed probe task, the size of the attentional focus was measured by letting participants respond to a probe occurring at varying positions. In all experiments, reaction time (RT) to the probe increased from the most central to more lateral probe positions. This V shaped probe-RT function, however, was not flattened by the presentation of an alerting signal. Overall, this pattern of results is inconsistent with the hypothesis that alerting signals increase the attentional focus. Instead, it is consistent with nonspatial accounts that attribute the increase in interference to an alerting effect on perceptual processing, which then leads to a detrimental effect at the level of response selection. PMID- 29168127 TI - Bioavailability of Orally Administered Des-Aspartate-Angiotensin I in Human Subjects. AB - In an earlier single-dose escalation study to evaluate the safety and pharmacokinetics of orally administered des-aspartate-angiotensin I (DAA-I) in healthy subjects, the plasma level of DAA-I could not be determined because DAA-I is rapidly degraded in the circulation. The present study investigated the oral bioavailability of DAA-I by measuring the prostaglandin E2 metabolite (PGEM) in the plasma samples of the same trial. PGEM is a stable derivative of PGE2, which has been shown to be a biomarker of DAA-I. The data show that plasma from two of the three subjects who were orally administered the efficacious preclinical dose of 0.70 mg/kg DAA-I exhibited a significant PGEM peak at 5-6 h postdose. Plasma of subjects who were administered 0.08 and 1.5 mg/kg DAA-I, the subefficacious and two-times efficacious dose, respectively, did not exhibit a similar PGEM peak. This observation is concordant with the known in vivo actions of DAA-I, especially its hypoglycemic action where maximum efficacy occurred at a dose of 0.7 mg/kg, and decreased to nil at the two-times efficacious dose. The onset of the PGEM peak at 5-6 h postdose was closed to the 4-h onset of absorption of [C14]DAA-I seen in preclinical rat studies, albeit the absorption kinetics between rodents and humans are not identical. The occurrence of polymorphism of enzymes involved in the formation and degradation of PGE2 is common, and this has been attributed to contributing to the variation in response, onset and peak PGEM observed among the three subjects who were administered the efficacious dose. PMID- 29168128 TI - Enhancement of Galantamine HBr Skin Permeation Using Sonophoresis and Limonene Containing PEGylated Liposomes. AB - This study aimed to investigate the effect of low-frequency sonophoresis (SN) and limonene-containing PEGylated liposomes (PL) on the transdermal delivery of galantamine HBr (GLT). To evaluate the skin penetration mechanism, confocal laser scanning microscopy (CLSM), Fourier transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC) were employed. The application of SN led to more GLT penetration into and through the skin than GLT solution alone. The liposomes also improved GLT permeation, and 2% limonene-containing PL (PL-LI2%) exhibited the highest GLT permeation, followed by PL-LI1%, PL-LI0.1%, and PL. The CLSM images of PL-LI2% resulted in the highest fluorescence intensity of fluorescent hydrophilic molecules in the deep skin layer, and the rhodamine PE labeled liposome membrane was distributed in the intercellular region of the stratum corneum (SC). PL-LI2% induced significant changes in intercellular lipids in the SC, whereas SN had no effect on intercellular lipids of the SC. DSC thermograms showed that the greatest decrease in the lipid transition temperature occurred in PL-LI2%-treated SC. SN might improve drug permeation through an intracellular pathway, while limonene-containing liposomes play an important role in delivering GLT through an intercellular pathway by increasing the fluidity of intercellular lipids in the SC. Moreover, a small vesicle size and high membrane fluidity might enhance the transportation of intact vesicles through the skin. PMID- 29168129 TI - Flavone protects HBE cells from DNA double-strand breaks caused by PM2.5. AB - Ambient air particulate matter 2.5 (PM2.5) contains many harmful components that can enter the circulatory system and produce reactive oxygen species (ROS) in body. Oxidative stress and DNA damage induced by ROS may affect any cellular macromolecule and lead to DNA double-strand breaks (DSBs). Flavonoids, widely distributed in some herbs and berries, have been proved having anti-oxidative or anti-cancer efficacy. In this study, we investigated whether Flavone, a kind of flavonoids, can protect human bronchial epithelial cells (HBE) from DSBs caused by PM2.5 and how this function is probably implemented. We found that cells exposed to PM2.5 obviously induced viability inhibition, DNA damage and part of apoptosis. However, Flavone treatment prior to PM2.5 apparently improved cell viability, and mitigated the formation of 8-hydroxy-2-deoxyguanosine, the expression of DNA damage-relative protein and cell apoptosis. Our studies demonstrated that PM2.5 induced oxidative DSBs while Flavone ameliorated the DNA damage and increased cell viability probably through influencing DNA repair mechanism of cells. PMID- 29168131 TI - The Relationship Between Spiritual Intelligence and Aggression Among Elite Wrestlers in Hamadan Province of IRAN. AB - The purpose of this study was to investigate the relationship between spiritual intelligence and aggression among elite wrestlers of adolescent age group. The present study was descriptive of correlation type in terms of method and applied in terms of purpose. The population of this research was the elite wrestlers of adolescents age group aged 14-17 (mean and SD of 15.27 +/- 1.33) using the convenient sampling method for adolescent wrestling teams of Hamedan clubs selected as samples. To measure variables, King's spiritual intelligence scale and Bass and Perry aggression questionnaire were used. Pearson correlation coefficient and simple regression method were used for data analysis. Results showed a significant negative relationship between spiritual intelligence and aggression. The spiritual intelligence scores also have a significant effect on aggression. The findings show that the higher the spiritual intelligence, the less likely the aggression of the elite wrestlers in different competitions and they can have a better performance than others. PMID- 29168130 TI - Tolerance towards gentamicin is a function of nutrient concentration in biofilms of patient-isolated Staphylococcus epidermidis. AB - Staphylococcus epidermidis is a biofilm-forming bacterial strain that can cause major problems as an agent of nosocomial infections. Bacteria in biofilms are shielded from the environment and can survive high doses of antibiotics. We here test the antibiotic susceptibility of Staphylococcus epidermidis to rising gentamicin concentrations in optimal growth conditions as used in routine bacteriology laboratories with low nutrient situations as suggested to be found in clinical situations. We found that gentamicin-resistant Staphylococcus epidermidis biofilms survived in the absence of external nutrient supply in PBS. While addition of gentamicin sulfate significantly reduced the pH value of all used media and solutions, this acidification did not alter survival of bacteria in the biofilm. We found a statistically significant and dose-dependent reduction of survival in low nutrient situations using gentamicin sulfate in three out of four patient isolates of Staphylococcus epidermidis which have been tested to be gentamicin-resistant under optimal growth conditions. Supporting the original profiling, survival in full media under the same antibiotic dosages was not significantly reduced. Our data here show that antibiotic resistance is a function of the provided nutrient concentration. Antibiotic resistance profiling should consider variations in nutrient availability. PMID- 29168132 TI - Heavy metals in the surface sediments of lakes on the Tibetan Plateau, China. AB - Heavy metal contamination has affected many regions in the world, particularly the developing countries of Asia. We investigated 8 heavy metals (Cu, Zn, Cd, Pb, Cr, Co, Ni, and As) in the surface sediments of 18 lakes on the Tibetan Plateau. It was found that the distributions of the heavy metals showed no clear spatial pattern on the plateau. The results indicated that the mean concentrations of these metals in the sediment samples diminished as follows: Cr > As > Zn > Ni > Pb > Cu > Co > Cd. The results of geoaccumulation index (I geo) and potential ecological risk factor (E ir ) assessments showed that the sediments were moderately polluted by Cd and As, which posed much higher risks than the other metals. The values of the potential ecological risk index (RI) showed that lake Bieruoze Co has been severely polluted by heavy metals. Principal component analysis, hierarchical cluster analysis, and Pearson correlation analysis results indicated that the 8 heavy metals in the lake surface sediments of the Tibetan Plateau could be classified into four groups. Group 1 included Cu, Zn, Pb, Co, and Ni which were mainly derived from both natural and traffic sources. Group 2 included Cd which mainly originated from anthropogenic sources like alloying, electroplating, and dyeing industries and was transported to the Tibetan Plateau by atmospheric circulation. Group 3 included Cr and it might mainly generate from parent rocks of watersheds. The last Group (As) was mainly from manufacturing, living, and the striking deterioration of atmospheric environment of the West, Central Asia, and South Asia. PMID- 29168133 TI - Assessment of oral and lung bioaccessibility of Cd and Pb from smelter-impacted dust. AB - Soil and dust contamination by metals engenders significant environmental and health problems in northern France where a lead smelter was in activity for more than a century. This study aims to examine the long-term effects of the smelter, 10 years after its closedown, on the presence of metal in sidewalk dust for a better assessment of the local population's exposure to Cd and Pb. The investigation included: (i) the metal distribution in different dust particle sizes and (ii) the assessment of metal bioaccessibility via ingestion and inhalation of dust. Seventy-two sidewalk dust samples were collected using a dust sampling vacuum. The samples were sieved to collect different particle sizes from 0.3 to 1000 MUm. The unified bioaccessibility method (UBM) was employed to evaluate the oral bioaccessibility of metals in the different particle sizes. The pulmonary bioaccessible fraction of Cd and Pb via the finest particles was extracted with lung-simulating solution (artificial lysosomal fluid). Ten years after the smelter closedown, (i) a strong relationship was observed between the concentrations of metals in dust and the distance to the former smelter, whatever the particle size; (ii) both total and oral bioaccessible concentrations of metals were high in the finest fraction (0.3-5 MUm) and decreased when the particle size increased; (iii) a higher oral bioaccessibility of Cd and Pb was measured in the gastric phase (on average 43% for both metals for all particle sizes) and compared to the gastrointestinal phase (on average 16% for both metals for all particle sizes); and (iv) metal bioaccessibility via inhalation of dust was relatively high (on average 74 and 69%, for Cd and Pb, respectively). The results of the present study suggest that this environmental compartment may be a sensitive and effective indicator of anthropogenic metal contamination and the human exposure in urban areas. PMID- 29168134 TI - Effects of soil properties and aging process on the acute toxicity of cadmium to earthworm Eisenia fetida. AB - This study was undertaken to investigate the effects of soil properties and aging process on the acute toxicity of cadmium (Cd) to Eisenia fetida (E. fetida) in 18 Cd-spiked soils. Results showed that the Cd toxicity to E. fetida differed in the 18 soils with different characteristics, and median lethal concentration (LC50) values varied from 440.7 to 1520.4 mg/kg in freshly spiked soils. Soil pH and organic matter (OM) content were the two major factors associated with Cd toxicity. The increase in LC50 values and decreases in both exchangeable Cd in soils and tissue Cd concentrations in earthworm whole body indicated that aging (180 and 360 days) could reduce the acute toxicity and bioavailability of Cd to E. fetida. Cadmium concentrations in E. fetida were positively correlated with exchangeable Cd content in soils, and soil pH and OM were the key factors controlling the distribution and transformation of the exchangeable Cd. The results will provide useful reference information for the risk assessment of Cd in the terrestrial environment. PMID- 29168135 TI - Visible light-induced photocatalytic degradation of Reactive Blue-19 over highly efficient polyaniline-TiO2 nanocomposite: a comparative study with solar and UV photocatalysis. AB - Polyaniline-TiO2 (PANI-TiO2) nanocomposite was prepared by in situ polymerisation method. X-ray diffractogram (XRD) showed the formation of PANI-TiO2 nanocomposite with the average crystallite size of 46 nm containing anatase TiO2. The PANI-TiO2 nanocomposite consisted of short-chained fibrous structure of PANI with spherical TiO2 nanoparticles dispersed at the tips and edge of the fibres. The average hydrodynamic diameter of the nanocomposite was 99.5 nm. The band gap energy was 2.1 eV which showed its ability to absorb light in the visible range. The nanocomposite exhibited better visible light-mediated photocatalytic activity than TiO2 (Degussa P25) in terms of degradation of Reactive Blue (RB-19) dye. The photocatalysis was favoured under initial acidic pH, and complete degradation of 50 mg/L dye could be achieved at optimum catalyst loading of 1 g/L. The kinetics of degradation followed the Langmuir-Hinshelhood model. PANI-TiO2 nanocomposite showed almost similar photocatalytic activity under UV and visible light as well as in the solar light which comprises of radiation in both UV and visible light range. Chemical oxygen demand removal of 86% could also be achieved under visible light, confirming that simultaneous mineralization of the dye occurred during photocatalysis. PANI-TiO2 nanocomposites are promising photocatalysts for the treatment of industrial wastewater containing RB-19 dye. PMID- 29168136 TI - Adsorption of cadmium ions using the bioadsorbent of Pichia kudriavzevii YB5 immobilized by polyurethane foam and alginate gels. AB - Pichia kudriavzevii YB5, mutated from Pichia kudriavzevii A16 with a strong ability to remove cadmium ions, was immobilized by polyurethane foam and alginate gels in this work. The immobilization conditions were optimized as follows: sodium alginate concentration of 2% (w/v), calcium chloride concentration of 2% (w/v), biomass dose of 1 * 109 cell/mL, and cross-linking time for 4 h. Then, the results of batch adsorption experiments showed that the removal capacity of prepared bioadsorbent was significantly affected by the pH of media, contact time, and the initial Cd(II) concentration, and a suitable adsorption conditions of Cd(II) could be achieved with a pH value of 6.0 at 20 degrees C for 90 min. Kinetic and isothermal results indicated the behavior of Cd(II) adsorption onto immobilized P. kudriavzevii YB5 fitted to the pseudo-second-order kinetic equation and the Langmuir adsorption model. Thermodynamic results showed that the Cd(II) adsorption process was endothermic and spontaneous in nature. Besides, the Cd(II) removing capacity of the prepared bioadsorbent was also tested in the oyster hydrolysates, showing an average removal rate of 54.35%. Thus, the immobilized P. kudriavzevii YB5 adsorbent had great potential for application in aquatic products to ensure the food safety. PMID- 29168137 TI - Pesticide residues in muscles of some marine fish species and seaweeds of Iskenderun Bay (Northeastern Mediterranean), Turkey. AB - Pesticide residues in muscles of nine marine fish and four seaweed species of Iskenderun Bay (Northeastern Mediterranean) have been investigated. In sampled fish species, two herbicides, three insecticides, two fungicides, and one synergist were identified and quantified. Metribuzin DADK, propamocarb HCl, and piperonyl butoxide (PBO) were detected in all the muscles of sampled fish species. Metribuzin DADK was the most abundant pesticide residue in fish muscles and the highest metribuzin DADK concentration was found in sardine (311.20 MUg/kg). Propamocarb HCl concentrations varied greatly among species; from 0.530 +/- 0.020 MUg/kg in striped sea bream to 34.170 MUg/kg in sea bass. The level of PBO ranged from 0.001 MUg/kg for fourlined terapon to 0.013 MUg/kg for sardine. No measurable oxamyl residue was found in any of the muscles of sampled fish species (except sardine). In seaweeds, two herbicides and two insecticides were identified and quantified. Metribuzin DADK was the most abundant and found in Cystoseira corniculata (5.01 mg/kg), Corallina elongata (0.703 mg/kg), and Jania rubens (3.85 mg/kg). Molinate was a minor contaminant and only found in Corallina elongata (0.002 mg/kg). Pyrethrin I was determined only in Padina pavonia to be 0.567 mg/kg. Pyrethrine II was found in Padina pavonia and Corallina elongate to be 1.214 and 0.229 mg/kg, respectively. The most hazardous pesticide residues of organochlorines and organophosphorus were not detected in both sampled fish muscles and seaweeds. There are no clear maximum residue limits for the detected eight pesticide residues declared for fish muscle by European Union MRL (2017). In conclusion, it can be considered that observed concentrations of pesticides in sampled nine marine fish species do not have a potential health risk for consumers. Some of the detected pesticide residues can be toxic for algae and aquatic life and regular monitoring studies are therefore essential to control the pesticide concentrations of aquatic biota in the region. PMID- 29168138 TI - Metabolomic analysis of the toxic effect of chronic exposure of cadmium on rat urine. AB - This study aimed to assess the toxic effect of chronic exposure to cadmium through a metabolomic approach based on ultra-performance liquid chromatography/mass spectrometry (UPLC-MS). Forty male Sprague-Dawley rats were randomly assigned to the following groups: control, low-dose cadmium chloride (CdCl2) (0.13 mg/kg body weight (bw)), middle-dose CdCl2 (0.8/kg bw), and high dose CdCl2 (4.9 mg/kg bw). The rats continuously received CdCl2 via drinking water for 24 weeks. Rat urine samples were then collected at different time points to establish the metabolomic profiles. Multiple statistical analyses with principal component analysis and partial least squares-discriminant analysis were used to investigate the metabolomic profile changes in the urine samples and screen for potential biomarkers. Thirteen metabolites were identified from the metabolomic profiles of rat urine after treatment. Compared with the control group, the treated groups showed significantly increased intensities of phenylacetylglycine, guanidinosuccinic acid, 4-pyridoxic acid, 4-aminohippuric acid, 4-guanidinobutanoic acid, allantoic acid, dopamine, LysoPC(18:2(9Z,12Z)), and L-urobilinogen. By contrast, the intensities of creatinine, L-carnitine, taurine, and pantothenic acid in the treated groups were significantly decreased. These results indicated that Cd disrupts energy and lipid metabolism. Meanwhile, Cd causes liver and kidney damage via induction of oxidative stress; serum biochemical indices (e.g., creatinine and urea nitrogen) also support the aforementioned results.

AB - Challenges of water and wastewater management in Alaska include the potential need for above-grade and freeze-protected piping, high unit energy costs and, in many rural areas, low population density and median annual income. However, recently developed net-zero water (NZW), i.e., nearly closed-loop, direct potable water reuse systems, can retain the thermal energy in municipal wastewater, producing warm treated potable water without the need for substantial water re heating, heat pumping or transfer, or additional energy conversion. Consequently, these systems are projected to be capable of saving more energy than they use in water treatment and conveyance, in the temperate USA. In this paper, NZW technology is reviewed in terms of potential applicability in Alaska by performing a hypothetical case study for the city of Fairbanks, Alaska. Results of this paper study indicate that in municipalities of Alaska with local engineering and road access, the use of NZW systems may provide an energy efficient water service option. In particular, case study modeling suggests hot water energy savings are equivalent to five times the energy used for treatment, much greater savings than in mid-latitudes, due largely to the substantially higher energy needed for heating water from a conventional treatment system and lack of need for freeze-protected piping. Further study of the applicability of NZW technology in cold regions, with expanded evaluation in terms of system-wide lifecycle cost, is recommended.

AB - BACKGROUND: Transanal total mesorectal excision (taTME) is a minimally invasive technique which was developed to overcome the difficulties associated with the "top-down" pelvic dissection by enabling a "bottom-up" dissection in patients with mid- and low rectal cancer. While this technique was primarily designed to manage tumors in the mid- and lower rectum, its spectrum of indications has been broadened to include benign colorectal pathologies. The aim of the present study was to assess our initial experience with taTME in patients undergoing restorative proctocolectomy for familial adenomatous polyposis (FAP). METHODS: All consecutive patients (undergoing prophylactic restorative proctocolectomy with IPAA for FAP using taTME between April and October 2016 at our institution) were included in the study. RESULTS: There were 8 patients (6 females and 2 males). The median age was 19.5 years (range 16-31 years). In all cases, surgery was successfully completed using with taTME. No perioperative complications were recorded. A median of 5 bowel movements (range 4-6 bowel movements) with intermittent anti-diarrheal medication was recorded in all cases. CONCLUSIONS: Our initial experience with 8 consecutive cases suggests taTME is safe and effective in patients undergoing prophylactic restorative proctocolectomy with IPAA for FAP.

AB - Chronic granulomatous disease (CGD) is a primary immunodeficiency caused by defects in any of the five subunits of the NADPH oxidase complex responsible for the respiratory burst in phagocytic leukocytes. Patients with CGD are at increased risk of life-threatening infections with catalase-positive bacteria and fungi and inflammatory complications such as CGD colitis. The implementation of routine antimicrobial prophylaxis and the advent of azole antifungals has considerably improved overall survival. Nevertheless, life expectancy remains decreased compared to the general population. Inflammatory complications are a significant contributor to morbidity in CGD, and they are often refractory to standard therapies. At present, hematopoietic stem cell transplantation (HCT) is the only curative treatment, and transplantation outcomes have improved over the last few decades with overall survival rates now > 90% in children less than 14 years of age. However, there remains debate as to the optimal conditioning regimen, and there is question as to how to manage adolescent and adult patients. The current evidence suggests that myeloablative conditioning results is more durable myeloid engraftment but with increased toxicity and high rates of graft versus-host disease. In recent years, gene therapy has been proposed as an alternative to HCT for patients without an HLA-matched donor. However, results to date have not been encouraging. with negligible long-term engraftment of gene corrected hematopoietic stem cells and reports of myelodysplastic syndrome due to insertional mutagenesis. Multicenter trials are currently underway in the United States and Europe using a SIN-lentiviral vector under the control of a myeloid specific promoter, and, should the trials be successful, gene therapy may be a viable option for patients with CGD in the future. PMID- 29168146 TI - Novel Direct Annuloplasty Fastener System for Minimally Invasive Mitral Valve Repair. AB - The development of less invasive approaches for mitral valve repair remains an important objective, particularly in patients with multiple comorbidities. We describe a novel method to affix a mitral valve annuloplasty ring in a minimally invasive manner. A delivery apparatus for an annuloplasty fastener system was designed. Two channels were created, one for advancing the annuloplasty ring, and another to accommodate the fastener applicator. Custom designed fasteners, either with a helical-shaped screw or a strap-shaped tack structure, were tested. Fasteners were primed within an application device and automatic alignment of fasteners was achieved to allow accurate firing of the fixators securing the ring. The delivery apparatus was constructed to be deployed within a 10 mm trocar through a left atrial approach. Using a cadaveric swine heart model, access to the mitral valve from the left atrium was obtained with insertion of a trocar. The delivery apparatus was accurately directed to the mitral annulus under echocardiographic guidance. Fasteners were placed along the annular plane to secure the annuloplasty ring. Both fastener designs achieved considerable fixation force; the helical-shaped screw was found to have significantly greater fixation force compared to the strap-shaped tack design. The annuloplasty ring remained intact and did not experience any structural deformity during the fixation process. The use of a novel fastener system was successful in deploying and securing a mitral valve annuloplasty ring. These promising results may have further application for minimally invasive mitral valve repairs. Additional evaluation of this procedure with pre-clinical in vivo animal studies is necessary. PMID- 29168147 TI - Generation and characterization of tissue-type plasminogen activator transgenic rats. AB - To address a species difference in the responsiveness to human recombinant tissue type plasminogen activator (rt-PA) between rats and humans, tPA transgenic (Tg) rats were generated and characterized. In the rats, transcriptional regulation of tPA was designed under the control of the endogenous tPA promoter. There were no significant differences in hematological parameters between the tPA Tg and non Tg rats. Plasma tPA concentration was significantly increased and serum free PAI-1 was significantly decreased in the tPA Tg rats. Significant overexpression of tPA mRNA in five major organs was also confirmed in the tPA Tg rats. In contrast, the extent of tPA mRNA induction by pathophysiological stimuli (focal cerebral ischemia) was comparable in the two strains. Earlier increase in the plasma D Dimer level was observed in the tPA Tg rats in a model of thromboembolism compared with the non Tg rats. On the other hand, there was no statistically significant prolongation of bleeding time in a rat model of bleeding between the two strains. rt-PA showed dose-related blood flow restoration in a rat model of thromboembolic stroke in the tPA Tg rats from a dose (1 mg/kg, i.v.) similar to clinical doses for human stroke patients. In conclusion, tPA Tg rats, in which tPA is overexpressed and endogenous fibrinolytic activity is enhanced without hemostatic abnormality, were generated. tPA Tg rats would be beneficial for the pharmacological and the toxicological evaluation of rt-PA and other various fibrinolytic enhancers.

AB - Despite morphological and ecological inconsistencies among species, all plagioporine opecoelids with a pedunculate ventral sucker are currently considered to belong in the genus Podocotyloides Yamaguti, 1934. We revise the genus based on combined morphological and phylogenetic analyses of novel material collected from haemulid fishes in Queensland waters that we interpret to represent species congeneric with the type-species, Pod. petalophallus Yamaguti, 1934, also known from a haemulid, off Japan. Our phylogenetic analysis demonstrates polyphyly of Podocotyloides; prompts us to resurrect Pedunculacetabulum Yamaguti, 1934; and suggests that Pod. brevis Andres & Overstreet, 2013, from a deep-sea congrid in the Caribbean, and Pod. parupenei (Manter, 1963) Pritchard, 1966 and Pod. stenometra Pritchard, 1966, from mullids and chaetodontids, respectively, on the Great Barrier Reef, may each represent a distinct genus awaiting recognition. Our revised concept of Podocotyloides requires a pedunculate ventral sucker, but also a uterine sphincter prior to the genital atrium, a petalloid cirrus appendage, restriction of the vitelline follicles to the hindbody, and for the excretory vesicle to reach to the level of the ventral sucker. Of about 20 nominal species, we recognise just three in Podocotyloides (sensu stricto): Pod. petalophallus, Pod. gracilis (Yamaguti, 1952) Pritchard, 1966 and Pod. magnatestes Aleshkina & Gaevskaya, 1985. We provide new records for Pod. gracilis, and propose two new species of Podocotyloides, Pod. australis n. sp. and Pod. brevivesiculatus n. sp., and one new Pedunculacetabulum species, Ped. inopinipugnus n. sp., all from haemulids. Podocotyloides australis is morphologically indistinguishable from Pod. gracilis, and exploits the same definitive host, but is genetically and biogeographically distinct. It is thus a cryptic species, the first such opecoelid to be formally named. PMID- 29168148 TI - Developing a bacteriophage cocktail for biocontrol of potato bacterial wilt. AB - Bacterial wilt is a devastating disease of potato and can cause an 80% production loss. To control wilt using bacteriophage therapy, we isolated and characterized twelve lytic bacteriophages from different water sources in Kenya and China. Based on the lytic curves of the phages with the pathogen Ralstonia solanacearum, one optimal bacteriophage cocktail, P1, containing six phage isolations was formulated and used for studying wilt prevention and treatment efficiency in potato plants growing in pots. The preliminary tests showed that the phage cocktail was very effective in preventing potato bacterial wilt by injection of the phages into the plants or decontamination of sterilized soil spiked with R. solanacearum. Eighty percent of potato plants could be protected from the bacterial wilt (caused by R. solanacearum reference strain GIM1.74 and field isolates), and the P1 cocktail could kill 98% of live bacteria spiked in the sterilized soil at one week after spraying. However, the treatment efficiencies of P1 depended on the timing of application of the phages, the susceptibility of the plants to the bacterial wilt, as well as the virulence of the bacteria infected, suggesting that it is important to apply the phage therapy as soon as possible once there are early signs of the bacterial wilt. These results provide the basis for the development of bacteriophagebased biocontrol of potato bacterial wilt as an alternative to the use of antibiotics. PMID- 29168150 TI - Phylogenetic relationships of the genus Armadolepis Spassky, 1954 (Eucestoda, Hymenolepididae), with descriptions of two new species from Palaearctic dormice (Rodentia, Gliridae). AB - Two new species of hymenolepidid cestodes belonging to the genus Armadolepis Spassky, 1954 are described from dormice (Gliridae) from the southern East European Plain and the northwestern Caucasus, Russia. Armadolepis (Bremserilepis) longisoma n. sp., with a rudimentary, unarmed rostellar apparatus is described from the fat dormouse Glis glis (Linnaeus) from the Republic of Adygeya, Russia. Additionally, A. (Armadolepis) dryomi n. sp., characterised by a well-developed rostellar apparatus and armed rhynchus is described from the forest dormouse Dryomys nitedula Pallas from Rostov Oblast', Russia. Armadolepis (Bremserilepis) longisoma n. sp. differs from A. (Bremserilepis) myoxi (Rudolphi, 1819) in having a substantially longer strobila and cirrus-sac, wider scolex and ovary and larger rostellar pouch and testes. Armadolepis (Armadolepis) dryomi n. sp. is distinguishable from A. (Armadolepis) spasskii Tenora & Barus, 1958, A. (Armadolepis) jeanbaeri Makarikov, 2017 and A. (Armadolepis) tenorai Makarikov, 2017 in having a substantially longer and wider strobila, and larger rostellar pouch and cirrus-sac. Furthermore, A. dryomi n. sp. can be distinguished from its congeners by the number and size of rostellar hooks and the arrangement of the testes. Phylogenetic affinities of Armadolepis were studied for the first time using partial sequences of the nuclear ribosomal 28S DNA gene. Phylogenetic analysis strongly supported the status of Armadolepis as a separate genus belonging to the "Rodentolepis clade". PMID- 29168151 TI - Capillaria appendigera n. sp. (Nematoda: Capillariidae) from the goldbanded jobfish Pristipomoides multidens (Day) (Lutjanidae) and new records of other intestinal capillariids from marine perciform fishes off Australia. AB - Based on light and scanning electron microscopical studies, a new nematode parasite, Capillaria appendigera n. sp. (Capillariidae), is described from the intestine of the goldbanded jobfish Pristipomoides multidens (Day) (Perciformes, Lutjanidae) from the Arafura Sea West, off the northern coast of Australia. The new species, belonging to the subgenus Procapillaria Moravec, 1987, differs from other congeneric species from fishes mainly in the length (0.92-1.13 mm), shape and structure of the spicule, obtuse spines on the spicule sheath and the structure of eggs. It is characterised, in the male, by the presence of two well developed dorsolateral caudal lobes, a pair of lateral papillae, a heavily sclerotised spicule with many rough transverse grooves covering almost the entice spicule surface (except for spicule ends), a spinose spicule sheath, and in the female, by a subterminal anus, mostly the presence of a large vulval appendage and by eggs (size 54-69 * 27-33 um) encapsulated by a conspicuous light-coloured superficial layer. Capillaria appendigera n. sp. is the 12th nominal species of capillariids recorded from fishes in Australian waters and the second known capillariid species parasitising fishes of the perciform family Lutjanidae. In addition, four unidentifiable, morphologically different types of capillariid females, probably representing undescribed species, were recorded from the intestines of marine fishes off the northern coast of Australia: Capillariidae gen. sp. 1 and Capillariidae gen. sp. 2 from Lutjanus johnii (Bloch) and L. malabaricus (Bloch & Schneider), respectively (both Lutjanidae), Capillariidae gen. sp. 3 from Protonibea diacanthus (Lacepede) (Sciaenidae) and Capillariidae gen. sp. 4 from Rachycentron canadum (Linnaeus) (Rachycentridae). PMID- 29168152 TI - Dermatomyositis and colorectal cancer: a systematic review. AB - BACKGROUND: Dermatomyositis (DM) is an idiopathic inflammatory myositis. The principal characteristics are cutaneous rash, muscle ache, and muscle weakness. In the past, associations have been established between DM and malignancy, including colorectal cancer. METHODS: A systematic PubMed and Scopus search was conducted. RESULTS: The median age of the patients was 65 years (range 40-82). The majority were female (17 out of 27, 63%). Adenocarcinoma was the most frequent histological type of colorectal neoplasm. DM manifested before the diagnosis of colorectal cancer in 21 out of 27 patients (77.8%). At the time of the first presentation, creatine kinase was at a median level of 514.5 U/L (range 50-11,744), and serum antibodies were present in 11 out of 27 patients (40.7%). Immediate improvement of DM symptoms after surgery occurred in 14 out of 26 patients (53.8%). Recurrence of cancer in the form of distal metastasis was present in 5 out of 26 patients (19.2%). Cancer recurrence occurred within a median of 7.9 months (range 2-21) after surgery. In 7 out of 26 patients (26.9%), DM symptoms recurred during the post-operative period. Death was reported in 23 out of 27 patients (85.2%). CONCLUSION: It is of paramount importance to perform a systematic diagnostic workup for malignancy, always including colonoscopy, in DM patients, since there is a high incidence of cancer in DM patients. Surgical treatment of colorectal tumors should precede the treatment of DM, as DM will frequently regress after a successful resection of malignancy. PMID- 29168154 TI - The Effect of Probiotics on Halitosis: a Systematic Review and Meta-analysis. AB - Although several studies have evaluated the inhibitory effect of probiotics on halitosis, findings are inconsistent. This systematic review and meta-analysis of randomized clinical trials (RCT) was conducted to summarize the evidence on the effect of probiotics on halitosis. RCT on any type of probiotic treatment with at least 2-week duration were identified through electronic databases (PubMed, EMBASE, Web of Science, and the Cochrane Central Register of Controlled Trials) and hand searched between 1946 and January 17, 2017. Primary outcomes were organoleptic (OLT) scores and volatile sulfur compounds (VSC). Standardized mean difference (SMD) and 95% confidence interval (CI) were calculated. Meta-analysis was conducted to synthesize the evidence. Of the 153 articles identified, three met the inclusion criteria. Meta-analysis revealed that OLT scores (SMD = - 1.93, 95% CI - 2.85 to - 1.02, P < 0.0001) were significantly lower in subjects who received probiotics than in placebo groups, but no significant difference was observed at the VSC concentration (SMD = - 0.02, 95% CI - 2.12 to 2.07, P = 0.98). Current evidence is supportive of recommending probiotics for the management of halitosis. Based on this review, transient (average of 2 weeks) dosing with probiotics (mainly Lactobacillus strains) has a moderate effect on halitosis regarding OLT scores, but we could not confirm the effects of probiotics on the VSC reduction. The available evidence is quantitatively and qualitatively insufficient for further recommendations, especially with regard to administration strategies and pretreatment. Future studies should aim for longer follow-up and standardized administration methods to prove or refute the effect of probiotics on halitosis.

AB - Microbial cell surface display technology can redesign cell surfaces with functional proteins and peptides to endow cells some unique features. Foreign peptides or proteins are transported out of cells and immobilized on cell surface by fusing with anchoring proteins, which is an effective solution to avoid substance transfer limitation, enzyme purification, and enzyme instability. As the most frequently used prokaryotic and eukaryotic protein surface display system, bacterial and yeast surface display systems have been widely applied in vaccine, biocatalysis, biosensor, bioadsorption, and polypeptide library screening. In this review of bacterial and yeast surface display systems, different cell surface display mechanisms and their applications in biocatalysis as well as biosensors are described with their strengths and shortcomings. In addition to single enzyme display systems, multi-enzyme co-display systems are presented here. Finally, future developments based on our and other previous reports are discussed.

AB - This study aimed at comparing the genome of Enterococcus faecalis B3A-B3B, a bacteriocinogenic strain recently isolated from a healthy Iraqi infant to those of Enterococci of clinical and beneficial grades. The putative genes gelE, cpd, efaAfm, ccf, agg, and cob coding for virulence factors were detected in B3A-B3B strain, which meanwhile resulted to be non-cytotoxic, non-hemolytic, devoid of inflammatory effects, and sensitive to most of the antibiotics tested except for clindamycin and trimethoprim, which resistance is usually ascribed to intrinsic nature. B3A-B3B strain was remarkable for its hydrophobicity, auto-aggregation, adhesion to human Caco-2 cells, and survival in simulated gastrointestinal conditions, and cholesterol assimilation fulfilling therefore key beneficial attributes. PMID- 29168156 TI - The anesthetic management of button battery ingestion in children. AB - PURPOSE: Injuries related to button battery ingestion are common in children. This review provides an outline of the epidemiology, pathophysiology, management, and anesthetic implications in children who have ingested a button battery. SOURCE: A literature search was conducted in the United States National Library of Medicine PubMed database using the terms "button battery ingestion" and "children' and "removal" and "surgery" and "anesthesia". Ninety-six articles published in English were found from 1983-2017, and 62 of these articles were incorporated into this review. Additionally, the Internet was searched with the terms "button battery ingestion and children" to identify further entities, organizations, and resources affiliated with button battery ingestion in children. These additional sources were studied and included in this review. PRINCIPAL FINDINGS: Button batteries are ubiquitous in homes and electronic devices. Since 2006, larger-diameter and higher-voltage batteries have become available. These are more likely to become impacted in the esophagus after ingestion and lead to an increase in severe morbidity and mortality due to caustic tissue injury. Children at the highest risk for complications are those under six years of age who have ingested batteries > 20 mm in diameter and sustain prolonged esophageal impaction at the level of the aortic arch with the negative pole oriented anteriorly. CONCLUSION: Anesthesiologists need to know about the epidemiology, pathophysiology, complications, and anesthetic management of children who have ingested button batteries. PMID- 29168157 TI - Perioperative implications of sodium-glucose cotransporter-2 inhibitors: a case series of euglycemic diabetic ketoacidosis in three patients after cardiac surgery. AB - PURPOSE: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) comprise the newest class of oral hypoglycemic agents approved for treating type II diabetes mellitus (DM-II). Their use, however, has been associated with the rare development of euglycemic diabetic ketoacidosis (euDKA). We present three cases of euDKA that occurred following elective coronary artery bypass grafting surgery. The role of the anesthesiologist in the prevention, diagnosis, and management of this complication is also discussed. CLINICAL FEATURES: Three patients receiving chronic SGLT2i therapy for DM-II (discontinued one to two days preoperatively) underwent cardiac surgery. On the first postoperative day, each exhibited nausea, vomiting, and tachypnea. Although these nonspecific postoperative findings are common, our patients also exhibited anion gap metabolic acidosis (pH < 7.3, anion gap > 12 mmol.L-1) with lower than anticipated serum glucose levels of < 14 mmol.L-1. Serum and urine ketone analyses confirmed a diagnosis of euDKA. After insulin and dextrose infusions were initiated, rapid resolution of the metabolic abnormalities occured. CONCLUSIONS: Anesthesiologists should recognize that patients receiving SGLT2i preoperatively are at risk of developing euDKA. Hence, based on the pharmacokinetics of SGLT2i, discontinuing the medication at least two days prior to surgery should minimize the risk. Diagnosing euDKA is challenging and often delayed because of its nonspecific signs and symptoms. When suspected, serum and urine ketones should be monitored to reduce the time to diagnosis and treatment. PMID- 29168158 TI - Assessment of attenuation correction for myocardial PET imaging using combined PET/MRI. AB - OBJECTIVE: To evaluate the frequency of artifacts in MR-based attenuation correction (AC) maps and their impact on the quantitative accuracy of PET-based flow and metabolism measurements in a cohort of consecutive heart failure patients undergoing combined PET/MR imaging. METHODS: Myocardial viability studies were performed in 20 patients following a dual-tracer protocol involving the assessment of myocardial perfusion (13N-NH3: 813 +/- 86 MBq) and metabolism (18F-FDG: 335 +/- 38 MBq). All acquisitions were performed using a fully integrated PET/MR system, with standard DIXON-attenuation correction (DIXON-AC) mapping for each PET scan. All AC maps were examined for spatial misalignment with the emission data, total lung volume, susceptibility artifacts, and tissue inversion (TI). Misalignment and susceptibility artifacts were corrected using rigid co-registration and retrospective filling of the susceptibility-induced gaps, respectively. The effects of the AC artifacts were evaluated by relative difference measures and perceived changes in clinical interpretations. RESULTS: Average respiratory misalignment of (7 +/- 4) mm of the PET-emission data and the AC maps was observed in 18 (90%) patients. Substantial changes in the lung volumes of the AC maps were observed in the test-retest analysis (ratio: 1.0 +/- 0.2, range: 0.8-1.4). Susceptibility artifacts were observed in 10 (50%) patients, while six (30%) patients had TI artifacts. Average differences of 14 +/ 10% were observed for PET images reconstructed with the artifactual AC maps. The combined artifact effects caused false-positive findings in three (15%) patients. CONCLUSION: Standard DIXON-AC maps must be examined carefully for artifacts and misalignment effects prior to AC correction of cardiac PET/MRI studies in order to avoid misinterpretation of biased perfusion and metabolism readings from the PET data. PMID- 29168159 TI - LOX-1 is a poor prognostic indicator and induces epithelial-mesenchymal transition and metastasis in pancreatic cancer patients. AB - PURPOSE: Pancreatic cancer (PC) is an aggressive type of cancer that exhibits a rapid progression. Previously LOX-1, which is a type II trans-membrane glycoprotein that is expressed in endothelial cells, has been found to be involved in the development of several types of cancer. As yet, however, the expression of LOX-1 and its functional consequences in PC have not been documented. The present study was aimed at investigating the prognostic relevance of LOX-1 expression in PC patients and at resolving its role in PC metastasis. METHODS: LOX-1 expression was assessed by immunohistochemistry on a tissue microarray containing samples from 98 PC patients. Kaplan-Meier analyses were performed to compare survival curves, whereas Cox regression analyses were performed to explore the independent prognostic value of LOX-1 expression on the overall survival (OS) of PC patients. Harrel's concordance index was applied to calculate the predictive accuracy of established models. In addition, in vitro scratch wound healing and Transwell assays were used to assess the effect of LOX 1 expression silencing and over-expression on PC cell migration and invasion, whereas Cell Counting Kit-8 (CCK8) and Flow Cytometry (FCM) assays were used to assess its effects on PC cell proliferation and apoptosis. RESULTS: We found that LOX-1 is highly expressed in the PC tumor tissues tested and is related to the occurrence of lymph node metastases, higher TNM stages and a poor OS. We also found that LOX-1 expression may serve as an independent prognostic factor for the OS of PC patients. Our in vitro assays revealed that LOX-1 expression may promote the migration and invasion of PC cells through epithelial-mesenchymal transition (EMT). No effect on PC cell proliferation was noted. CONCLUSIONS: From our data we conclude that a high LOX-1 expression in PC tissues is indicative for the occurrence of lymph node metastases, high TNM stages and a poor prognosis. LOX-1 may serve as an independent prognostic biomarker. Our in vitro assays additionally revealed that LOX-1 may enhance the migration and invasion of PC cells through EMT. LOX-1 may also serve as a novel therapeutic target. PMID- 29168160 TI - Cladribine to Treat Relapsing Forms of Multiple Sclerosis. AB - Cladribine is a purine nucleoside analogue that selectively depletes peripheral lymphocytes without a major impact on cells of the innate immune system. An oral formulation of cladribine has been developed to be given as short courses over two annual cycles. Oral cladribine results in the peripheral depletion of lymphocytes that is gradual, occurring over several weeks, and is not associated with a cell lysis syndrome, has a greater impact on B cells than T cells, and is followed by gradual reconstitution of the peripheral lymphocyte counts over several months. Oral cladribine is effective in relapsing forms of multiple sclerosis. As a selective immune reconstitution therapy (SIRT), cladribine acts as a short-term immunosuppressant, relative to other maintenance immunosuppressive therapies that result in long-term immunosuppression. The main safety signal that has emerge relates primarily to herpes zoster infection, which was more common in patients with higher grades of lymphopenia, in particular grade 3 and 4 lymphopenia. Data from the oral cladribine extension trial and safety register, and reanalysis of the pivotal phase III trial has indicated that oral cladribine is unlikely to be associated with an increased short- to intermediate-term risk of malignancy. PMID- 29168161 TI - A Multilevel Approach to Breastfeeding Promotion: Using Healthy Start to Deliver Individual Support and Drive Collective Impact. AB - Purpose Breastfeeding has been linked to a host of positive health effects for women and children. However, disparities in breastfeeding initiation and duration prevent many low-income and African-American women from realizing these benefits. Existing breastfeeding promotion efforts often do not reach women who need support the most. In response, the Westside Healthy Start program (WHS), located in Chicago, Illinois, developed an ongoing multilevel approach to breastfeeding promotion. Description Key elements of our WHS breastfeeding model include individual education and counseling from pregnancy to 6 months postpartum and partnership with a local safety-net hospital to implement the Baby-Friendly Hospital Initiative and provide lactation support to delivering patients. Assessment In the year our model was implemented, 44.6% (49/110) of prenatal WHS participants reported that they planned to breastfeed, and 67.0% (183/273) of delivered participants initiated. Among participants reaching 6 months postpartum, 10.5% (9/86) were breastfeeding. WHS also had 2667 encounters with women delivering at our partner hospital during breastfeeding rounds, with 65.1% of contacts initiating. Community data was not available to assess the efficacy of our model at the local level. However, WHS participants fared better than all delivering patients at our partner hospital, where 65.0% initiated in 2015. Conclusion Healthy Start programs are a promising vehicle to improve breastfeeding initiation at the individual and community level. Additional evaluation is necessary to understand barriers to duration and services needed for this population. PMID- 29168162 TI - House Parties: An Innovative Model for Outreach and Community-Based Health Education. AB - Purpose To connect low resource communities to innovative services that address gaps in health access and knowledge. Description We describe the house party model, as a community-based workshop approach to health education developed by the Westside Healthy Start program (WHS) in Chicago, Illinois. Key elements of the WHS house party model include use of community health workers as facilitators, collaboration with participants and community-based organizations, referrals to health care and social services, and engagement strategies such as interactive activities, personal stories, and discussion. Assessment In 2014 and 2015, WHS completed 23 house parties with 271 participants, delivering education on relevant maternal and child health (MCH) topics. Participants demonstrated improvements in knowledge of several health-related areas. About half of participants were able to identify causes or signs of preterm labor prior to the house party, compared to over 80% after. In addition, 94% of participants rated the house party workshops "excellent" or "good". Conclusion House parties are a promising strategy for increasing knowledge about MCH topics and linking hard-to reach populations to resources in the community.

Methods Five safety net dental practices participated in a 15-month learning collaborative utilizing business assessments, QI training, early childhood oral health training, and prenatal oral health training. Practices collected monthly data on: net revenue, no-show rates, total encounters, and number of encounters for young children and pregnant women. We analyzed quantitative data using paired t-tests before and after the collaborative and collected supplemental qualitative feedback from clinic staff through focus groups and directed email. Results All mean measures improved, including: higher monthly revenue ($28,380-$33,102, p = 0.37), decreased no-show rate (17.7-14.3%, p = 0.11), higher monthly dental health encounters (283-328, p = 0.08), and higher monthly encounters for young children (8.8-10.5, p = 0.65), and pregnant women (2.8-9.7, p = 0.29). Results varied by practice, with some demonstrating largest increases in encounters for young children and others pregnant women. Focus group participants reported that the collaborative improved access for pregnant women and young children, and that QI methods were often new and difficult. Conclusion for practice Participation by safety net dental practices in a QI collaborative is feasible and acceptable. Individual sites saw greater improvements in different outcomes areas, based on their own structures and needs. Future efforts should focus on specific needs of each dental practice and should offer additional QI training. PMID- 29168164 TI - Meeting patient expectations: patient expectations and recovery after hip or knee surgery. AB - BACKGROUND: Although patient-centred care could help increase the value of healthcare, practice variations in hip and knee surgery suggest that physicians guide clinical decisions more than patients do. This raises the question whether treatment outcomes still meet patients' expectations. This study investigated whether treatment outcomes measured by patient-reported outcome measures fulfil patients' main expectations (i.e. decreased pain or improved functioning). METHODS: Patients who underwent hip or knee surgery in 20 Dutch hospitals in 2014 were invited to a survey consisting of the KOOS Physical Function Short Form or the HOOS Physical Function Short Form, the NRS pain and the EQ-5D. Patients were asked their main reason for surgery and whether the expectations regarding this reason were fulfilled. RESULTS: A total of 2776 patients completed the survey. The most common reason for surgery was improved functioning (43.7%). Patients who were unable to choose between pain relief and improved functioning and patients who aimed for pain relief experienced more problems before surgery. However, patients who were unable to choose improved more than patients who wanted to improve their functioning on the NRS pain during use and the EQ-5D. More patients who aimed for pain relief felt that their expectations were fulfilled compared to other patients. CONCLUSIONS: Although an expectation for an outcome was not related to a greater improvement on that outcome, patient expectations were an indication of patients' improvement due to surgery. Differences in expectation fulfilment may be due to unrealistic expectations. To achieve optimal value, tailoring treatment using patient preferences and managing patient expectations is vital. PMID- 29168165 TI - Ergotamine Use and Overuse in Taiwan: A Retrospective Cohort Study. AB - OBJECTIVE: The aim of this study was to investigate the pattern of ergotamine prescription and overuse in Taiwan. BACKGROUND: Ergotamine is a frequently prescribed medication for the treatment of migraine, although excessive use may lead to medication-overuse headache. METHODS: We conducted a retrospective cohort study by using the Longitudinal Health Insurance Database 2005 in Taiwan. Patients enrolled in the study were between the ages of 18 and 80 years, received at least two prescriptions of ergotamine, and follow-up for more than 1 year at outpatient clinics during 1999 to 2013. Each ergotamine prescription was converted into a defined daily dose (DDD) and patients were sorted into two groups: occasional users, having fewer than 3 consecutive months of use, and regular users, with 3 consecutive months of use or more. Regular users were further divided into overusers (DDDs >= 10 per month) and non-overusers. RESULTS: A total of 41,023 migraine patients were enrolled in the study; 5803 patients were classified as regular users, with 859 of those being overusers. Of the ergotamine overusers, around 698/859 (82%) continued to use, and 443/859 (52%) remained overusers of ergotamine in the subsequent year after the index date. The most frequently prescribed prophylactic medications were propranolol and flunarizine, which were prescribed in 30.4% and 20.0% of overuse patients, respectively. CONCLUSIONS: Ergotamine overuse remains common in Taiwan, while prophylactic medicine is still underutilized. More education on ergotamine overuse headache is needed to improve awareness.

PMID- 29168167 TI - Interdependent feedback regulation of breathing by the carotid bodies and the retrotrapezoid nucleus. AB - The retrotrapezoid nucleus (RTN) regulates breathing in a CO2 - and state dependent manner. RTN neurons are glutamatergic and innervate principally the respiratory pattern generator; they regulate multiple aspects of breathing, including active expiration, and maintain breathing automaticity during non-REM sleep. RTN neurons encode arterial PCO2 /pH via cell-autonomous and paracrine mechanisms, and via input from other CO2 -responsive neurons. In short, RTN neurons are a pivotal structure for breathing automaticity and arterial PCO2 homeostasis. The carotid bodies stimulate the respiratory pattern generator directly and indirectly by activating RTN via a neuronal projection originating within the solitary tract nucleus. The indirect pathway operates under normo- or hypercapnic conditions; under respiratory alkalosis (e.g. hypoxia) RTN neurons are silent and the excitatory input from the carotid bodies is suppressed. Also, silencing RTN neurons optogenetically quickly triggers a compensatory increase in carotid body activity. Thus, in conscious mammals, breathing is subject to a dual and interdependent feedback regulation by chemoreceptors. Depending on the circumstance, the activity of the carotid bodies and that of RTN vary in the same or the opposite directions, producing additive or countervailing effects on breathing. These interactions are mediated either via changes in blood gases or by brainstem neuronal connections, but their ultimate effect is invariably to minimize arterial PCO2 fluctuations. We discuss the potential relevance of this dual chemoreceptor feedback to cardiorespiratory abnormalities present in diseases in which the carotid bodies are hyperactive at rest, e.g. essential hypertension, obstructive sleep apnoea and heart failure. PMID- 29168169 TI - Response to clobazam in continuous spike-wave during sleep. AB - AIM: To evaluate the efficacy of clobazam treatment in reducing epileptiform discharges and modifying neuropsychological function in continuous spike-wave during slow wave sleep. METHOD: We performed a prospective clinical trial in patients with continuous spike-wave during sleep aged 4 to 10 years. Patients underwent neuropsychological assessment and overnight electroencephalographic monitoring before treatment, and subsequent repeat assessment and overnight electroencephalographic monitoring 3 months after treatment. Treatment consisted of 1mg/kg clobazam up to a maximum dose of 30mg during the first night, followed by 0.5mg/kg nightly for 3 months. RESULTS: Nine patients completed the study and had pre- and post-neuropsychological evaluation. There was a qualitative reduction in median (p25 -p75 ) spike percentage after 3 months (72.2 [68.0-75.8] vs 32.7 [4.7-81.7]). There were no marked changes in median (p25 -p75 ) IQ comparing pre- and post-clobazam treatment (80.0 [74.0-88.0] vs 80.0 [67.0 89.0]). There was a qualitative increase in Verbal IQ (83.0 [69.0-92.0] vs 95.0 [83.0-99.0]) and a qualitative decrease in Non-verbal IQ (84.0 [74.0-87.0] vs 71.0 [60.0-84.0]). INTERPRETATION: Qualitative improvements in epileptiform activity and cognition occurred in patients treated with clobazam for 3 months and the relationship between epileptiform activity and cognitive outcome should be studied in larger studies. WHAT THIS PAPER ADDS: Verbal IQ in patients with continuous spike-wave during sleep improved following short-term treatment with clobazam. Other neuropsychological improvements were observed, but varied by patient. Cognitive improvement was observed despite some worsening of epileptiform discharges. PMID- 29168170 TI - Platelets derived from fresh and cold-stored whole blood participate in clot formation in rats with acute traumatic coagulopathy. AB - The in vitro haemostatic functions of fresh whole blood (FWB) are well preserved after cold storage. This study aimed to determine whether platelets derived from FWB and stored whole blood (SWB) contribute to clot formation in tissue injury after transfusion into coagulopathic rats with polytrauma/haemorrhage (T/H). The rats were resuscitated 1 h after trauma with FWB or SWB collected from green fluorescence protein (GFP) transgenic rats. After transfusion, a liver incision was made and the tissue was collected 10 min after injury to identify GFP+ platelets by immunohistochemistry. In comparison to FWB, platelet aggregation to adenosine diphosphate and protease-activated receptor-4 was reduced by 35% and 20%, and clotting time was shortened by 25% in SWB. After transfusion, SWB led to a significant increase in platelet activation as measured by an elevation of CD62P and phosphatidylserine expression. The platelets from SWB were in a higher activation state, and showed higher clearance rate and formation of platelet leucocyte aggregates than those from FWB after transfusion. Platelets from both FWB and SWB were equivalently incorporated into the clot at the incisional site, as determined by co-localization of CD61 and GFP. This study suggests that SWB contributes to haemostatic function and is an effective alternative resource to treat trauma patients. PMID- 29168172 TI - Extracellular adenosine-induced Rac1 activation in pulmonary endothelium: Molecular mechanisms and barrier-protective role. AB - We have previously shown that Gs-coupled adenosine receptors (A2a) are primarily involved in adenosine-induced human pulmonary artery endothelial cell (HPAEC) barrier enhancement. However, the downstream events that mediate the strengthening of the endothelial cell (EC) barrier via adenosine signaling are largely unknown. In the current study, we tested the overall hypothesis that adenosine-induced Rac1 activation and EC barrier enhancement is mediated by Gs dependent stimulation of cAMP-dependent Epac1-mediated signaling cascades. Adenoviral transduction of HPAEC with constitutively-active (C/A) Rac1 (V12Rac1) significantly increases transendothelial electrical resistance (TER) reflecting an enhancement of the EC barrier. Conversely, expression of an inactive Rac1 mutant (N17Rac1) decreases TER reflecting a compromised EC barrier. The adenosine induced increase in TER was accompanied by activation of Rac1, decrease in contractility (MLC dephosphorylation), but not Rho inhibition. Conversely, inhibition of Rac1 activity attenuates adenosine-induced increase in TER. We next examined the role of cAMP-activated Epac1 and its putative downstream targets Rac1, Vav2, Rap1, and Tiam1. Depletion of Epac1 attenuated the adenosine-induced Rac1 activation and the increase in TER. Furthermore, silencing of Rac1 specific guanine nucleotide exchange factors (GEFs), Vav2 and Rap1a expression significantly attenuated adenosine-induced increases in TER and activation of Rac1. Depletion of Rap1b only modestly impacted adenosine-induced increases in TER and Tiam1 depletion had no effect on adenosine-induced Rac1 activation and TER. Together these data strongly suggest that Rac1 activity is required for adenosine-induced EC barrier enhancement and that the activation of Rac1 and ability to strengthen the EC barrier depends, at least in part, on cAMP-dependent Epac1/Vav2/Rap1-mediated signaling. PMID- 29168171 TI - The arginine metabolome in acute lymphoblastic leukemia can be targeted by the pegylated-recombinant arginase I BCT-100. AB - Arginine is a semi-essential amino acid that plays a key role in cell survival and proliferation in normal and malignant cells. BCT-100, a pegylated (PEG) recombinant human arginase, can deplete arginine and starve malignant cells of the amino acid. Acute lymphoblastic leukemia (ALL) is the most common cancer of childhood, yet for patients with high risk or relapsed disease prognosis remains poor. We show that BCT-100 is cytotoxic to ALL blasts from patients in vitro by necrosis, and is synergistic in combination with dexamethasone. Against ALL xenografts, BCT-100 leads to a reduction in ALL engraftment and a prolongation of survival. ALL blasts express the arginine transporter CAT-1, yet the majority of blasts are arginine auxotrophic due to deficiency in either argininosuccinate synthase (ASS) or ornithine transcarbamylase (OTC). Although endogenous upregulation or retroviral transduced increases in ASS or OTC may promote ALL survival under moderately low arginine conditions, expression of these enzymes cannot prevent BCT-100 cytotoxicity at arginine depleting doses. RNA-sequencing of ALL blasts and supporting stromal cells treated with BCT-100 identifies a number of candidate pathways which are altered in the presence of arginine depletion. Therefore, BCT-100 provides a new clinically relevant therapeutic approach to target arginine metabolism in ALL. PMID- 29168173 TI - The role of melatonin on chemotherapy-induced reproductive toxicity. AB - OBJECTIVES: Reproductive malfunctions after chemotherapy still are a reason of reducing fertility and need specialized intensive care. The aim of this review was to investigate the effect of melatonin on the reproductive system under threatening with chemotherapeutic drugs. METHODS: To find the role of melatonin in the reproductive system during chemotherapy, a full systematic literature search was carried out based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in the electronic databases up to 17 April 2017 using search terms in the titles and abstracts. A total of 380 articles are screened according to our inclusion and exclusion criteria. Finally, 18 articles were included in this study. KEY FINDINGS: It has been cleared that melatonin has bilateral effects on reproductive cells. Melatonin protects normal cells via mechanisms, including decrease in oxidative stress, apoptosis, inflammation and modulating mitochondrial function, and sexual hormones. Furthermore, melatonin with antiproliferative properties and direct effects on its receptors improves reproductive injury and function during chemotherapy. On the other hand, melatonin sensitizes the effects of chemotherapeutic drugs and enhances chemotherapy-induced toxicity in cancerous cells through increasing apoptosis, oxidative stress and mitochondrial malfunction. CONCLUSIONS: The study provides evidence of the bilateral role of melatonin in the reproductive system during chemotherapy. PMID- 29168175 TI - Prognosis of status epilepticus in elderly patients. AB - PURPOSE: To evaluate the clinical features and prognosis of status epilepticus (SE) in patients above 70 years old. METHODS: Retrospective analysis of all patients >=70 years old with SE registered prospectively during 4 years. Follow up after discharge was performed. RESULTS: Ninety patients were evaluated. Acute symptomatic etiology was the most prevalent. The mean number of antiepileptic drugs (AEDs) used was 2.7 +/- 1.2, and 21% of the patients required sedation. A poor outcome was considered when death (31.1%) or developing of new neurological impairment at discharge (32.2%) occurred. After multivariate analysis, four variables predicted a poor outcome: acute symptomatic etiology (OR: 6.320; 95% CI: 1.976-20.217; P = .002), focal motor SE type (OR: 9.089; 95% CI: 2.482 33.283; P = .001), level of consciousness (OR: 4.596; 95% CI: 1.903-11.098; P = .001), and SE duration >12 hours (OR: 3.763; 95% CI: 1.130-12.530; P = .031). Independent predictive factors of mortality were SE duration >12 hours (OR: 4.306; 95% CI: 1.044-17.757; P = .043), modified Status Epilepticus Severity Score (mSTESS) (OR: 2.216; 95% CI: 1.313-3.740; P = .003), and development of complications (OR: 3.334; 95% CI: 1.004-11.070, P = .049). Considering long-term mortality, age (HR 1.036; 95% CI 1.001-1.071; P = .044), a potentially fatal underlying cause (HR 2.609; 95% CI 1.497- 4.548; P = .001), and mSTESS score >4 (HR 1.485; 95% CI 1.158-1.903; P = .002) remained as predictive factors. There was no association between sedation and the number of AEDs used with outcome at discharge or long-term mortality (P > .05). CONCLUSIONS: SE above 70 years old has a high morbimortality. Prognosis is not related to treatment aggressiveness. PMID- 29168176 TI - A meta-analysis of the relationship between rational beliefs and psychological distress. AB - OBJECTIVE: Rational emotive behavior therapy (REBT) model of psychological health assumes that rational beliefs cause functional emotions and adaptive behavior, but the presumed role of rational beliefs as protective factor against psychological distress/disorders is still in debate. An important step in validating an evidence-based therapy is to investigate the underling theoretical assumptions. Thus, the aim of the present meta-analysis is to investigate the direction and magnitude of the relationship between rational beliefs and psychological distress. METHOD: Our search identified 26 studies that met our criteria. We evaluated the effect size using the random-effects model and we tested the moderator role of several variables. RESULTS: The overall results revealed a medium negative association between rational beliefs and psychological distress, r = -0.31. The strongest association was found for unconditional acceptance beliefs (r = -0.41). CONCLUSION: The results add empirical evidence for the underling theory of REBT and revealed that the strength of the association between rational beliefs and distress is robust for a wide range of emotional problems. Therefore, rational beliefs could be a trans-diagnostic protective factor against distress. Moreover, results emphasized that rational beliefs type is an important factor, suggesting an increased focus in therapy on the developing of unconditional acceptance and self-acceptance beliefs. PMID- 29168174 TI - Genetic variants in the platelet-derived growth factor subunit B gene associated with pancreatic cancer risk. AB - The platelet-derived growth factor (PDGF) signaling pathway plays important roles in development and progression of human cancers. In our study, we aimed to identify genetic variants of the PDGF pathway genes associated with pancreatic cancer (PC) risk in European populations using three published genome-wide association study datasets, which consisted of 9,381 cases and 7,719 controls. The expression quantitative trait loci (eQTL) analysis was also performed using data from the 1000 Genomes, TCGA and GTEx projects. As a result, we identified two potential susceptibility loci (rs5757573 and rs6001516) of PDGFB associated with PC risk [odds ratio (OR) = 1.10, 95% confidence interval (CI) = 1.05-1.16, and p = 4.70 * 10-5 for the rs5757573 C allele and 1.21, 1.11-1.32, and 2.01 * 10 5 for the rs6001516 T allele]. Haplotype analysis revealed that the C-T haplotype carriers had a significantly increased risk of PC than those carrying the T-C haplotype (OR = 1.23, 95% CI = 1.12-1.34, p =5.00 * 10-6 ). The multivariate regression model incorporating the number of unfavorable genotypes (NUGs) with age and sex showed that carriers with 1-2 NUGs, particularly among 60-70 age group or males, had an increased risk of PC, compared to those without NUG. Furthermore, the eQTL analysis revealed that both loci were correlated with a decreased mRNA expression level of PDGFB in lymphoblastoid cell lines and pancreatic tumor tissues (p = 0.015 and 0.071, respectively). Our results suggest that genetic variants in PDGFB may play a role in susceptibility to PC. Further population and functional validations of our findings are warranted. PMID- 29168177 TI - Tumor characteristics and prognosis in women with pregnancy-associated breast cancer. AB - There is evidence of poor prognosis in women with pregnancy-associated breast cancer (PABC) diagnosed during pregnancy or within 2 years of delivery. Using a large, population-based cohort, we examined clinicopathologic features and survival in women with PABC. A cohort of women diagnosed with invasive breast cancer between 1992 and 2009 at ages 15-44 years was identified in the Swedish Cancer Register and the Breast Cancer Quality Registers. Dates of childbirths for each woman were retrieved from the Swedish Multi-Generation Register. Age standardized distributions of tumor stage (tumor size, nodal status, metastasis), Elston grade and ER/PR/HER2 status were compared between nulliparous women and women with breast cancer during pregnancy and up to 10 years postdelivery. Adjusted hazard ratios for all-cause mortality rates among patients were estimated using Cox regression. We identified 1,661 nulliparous women with breast cancer, 778 women with PABC (97 during pregnancy, 270 within first and 411 within second year postdelivery) and 3,598 during 2-10 years postdelivery. Compared to nulliparous women, women with PABC, and especially women diagnosed 0-12 months after delivery, had more advanced T and N stage, and higher proportions of ER/PR negative, HER2 positive and triple-negative tumors. Increased hazard ratios were observed in women diagnosed within 5 years of delivery after adjustment for age, year, education and region. Following additional adjustment for tumor characteristics, the hazard ratios were attenuated and nonsignificant. The poorer prognosis observed in women with PABC appears to be largely explained by more adverse tumor characteristics at diagnosis. PMID- 29168178 TI - The development of neuromotor skills and hand preference during infancy. AB - Assessing infant handedness has been controversial. Different assessment techniques and theoretical approaches produce different results. Evidence from a dynamic systems perspective showed that the development of postural control during infancy affects the expression of an infant's handedness. However, others found that developmental changes in postural control influenced the amount of symmetrical (bimanual) reaching during infancy, but not hand preference. Since most studies of infant handedness use age to assess development, perhaps measures of an infant's developing neuromotor control, irrespective of age, would better predict changes in an infant's hand preference. To assess neuromotor development, items from [Touwen's (1976) Neurological development in infancy. Lavenham, Suffolk: The Lavenham Press, LTD]. "Group III" indices were used. These items assess developmental changes in neuromotor abilities throughout the 6-14-month age period. Hand preference for acquiring objects was measured during these same months. Group Based Trajectory Models (GBTM) of 380 infants identified four different groups of infants according to the trajectory of the development of their hand preferences (32% Early Right, 12% Early Left, 25% Late Right, 30% No Preference). A multilevel model was used to compare these four developmental trajectories according to age and neuromotor development. Age, not neuromotor development, is a better predictor of differences in developmental trajectories of the four hand preference groups. However, Late Right infants are significantly less developed at 6 months than No Preference, Early Right and Left infants and both Early Right and Left infants are most advanced at 6 months. All groups exhibit similar rates of neuromotor development indicating no "catch-up" by the Late Right infants. Thus, any assessment of infant handedness will incorporate necessarily four groups of infants with differently developing hand preferences and neuromotor abilities. PMID- 29168179 TI - Phenolic and physicochemical stability of a functional beverage powder mixture during storage: effect of the microencapsulant inulin and food ingredients. AB - BACKGROUND: The need for a convenience herbal iced tea product with reduced kilojoules merited investigation of the shelf-life of powder mixtures containing a green Cyclopia subternata Vogel (honeybush) extract with proven blood glucose lowering activity and alternative sweetener mixture. RESULTS: Prior to long-term storage testing, the wettability of powder mixtures containing food ingredients and the compatibility of their components were confirmed using the static sessile drop method and isothermal microcalorimetry, respectively. The powders packed in semi-sealed containers remained stable during storage at 25 degrees C/60% relative humidity (RH) for 6 months, except for small losses of specific phenolic compounds, namely mangiferin, isomangiferin, 3-beta-d glucopyranosyliriflophenone, vicenin-2 and 3',5'-di-beta-d glucopyranosylphloretin, especially when both citric acid and ascorbic acid were present. These acids drastically increased the degradation of phenolic compounds under accelerated storage conditions (40 degrees C/75% RH). Accelerated storage also caused changes in the appearance of powders and the colour of the reconstituted beverage solutions. Increased moisture content and aw of the powders, as well as moisture released due to dehydration of citric acid monohydrate, contributed to these changes. CONCLUSION: A low-kilojoule honeybush iced tea powder mixture will retain its functional phenolic compounds and physicochemical properties during shelf-life storage at 25 degrees C for 6 months.

AB - Staphylococcus aureus is the main pathogen associated with septic arthritis. Upon infection, neutrophils are quickly recruited to the joint by different chemoattractants, especially CXCR1/2 binding chemokines. Although their excessive accumulation is associated with intense pain and permanent articular damage, neutrophils have an important function in controlling bacterial burden. This work aimed to study the role of CXCR2 in the control of infection, hypernociception and tissue damage in S. aureus-induced septic arthritis in mice. The kinetics of neutrophil recruitment correlated with the bacterial load recovered from inflamed joint after intra-articular injection of S. aureus. Treatment of mice from the start of infection with the non-competitive antagonist of CXCR1/2, DF2156A, reduced neutrophil accumulation, cytokine production in the tissue, joint hypernociception and articular damage. However, early DF2156A treatment increased the bacterial load locally. CXCR2 was important for neutrophil activation and clearance of bacteria in vitro and in vivo. Start of treatment with DF2156A 3 days after infection prevented increase in bacterial load and reduced the hypernociception in the following days, but did not improve tissue damage. In conclusion, treatment with DF2156A seems be effective in controlling tissue inflammation and dysfunction but its effects are highly dependent on the timing of the treatment start.

PMID- 29168181 TI - Different interleukin-17-secreting Toll-like receptor+ T-cell subsets are associated with disease activity in multiple sclerosis. AB - Signalling through Toll-like receptors (TLRs) may play a role in the pathogenesis of autoimmune diseases, such as multiple sclerosis (MS). In the present study, the expression of TLR-2, -4 and -9 was significantly higher on CD4+ and CD8+ T cells from MS patients compared to healthy individuals. Following in-vitro activation, the proportion of interleukin (IL)-17+ and IL-6+ CD4+ and CD8+ T cells was higher in the patients. In addition, the proportion of IFN-gamma secreting TLR+ CD8+ T-cells was increased in MS patients. Among different IL-17+ T-cell phenotypes, the proportion of IL-17+ TLR+ CD4+ and CD8+ T-cells producing IFN-gamma or IL-6 were positively associated with the number of active brain lesions and neurological disabilities. Interestingly, activation of purified CD4+ and CD8+ T-cells with ligands for TLR-2 (Pam3Csk4), TLR-4 [lipopolysaccharide (LPS)] and TLR-9 [oligodeoxynucleotide (ODN)] directly induced cytokine production in MS patients. Among the pathogen-associated molecular patterns (PAMPs), Pam3Csk4 was more potent than other TLR ligands in inducing the production of all proinflammatory cytokines. Furthermore, IL-6, IFN-gamma, IL-17 and granulocyte-macrophage colony-stimulating factor (GM-CSF) levels produced by Pam3Csk4-activated CD4+ cells were directly associated with disease activity. A similar correlation was observed with regard to IL-17 levels released by Pam3Csk4 stimulated CD8+ T-cells and clinical parameters. In conclusion, our data suggest that the expansion of different T helper type 17 (Th17) phenotypes expressing TLR 2, -4 and -9 is associated with MS disease activity, and reveals a preferential ability of TLR-2 ligand in directly inducing the production of cytokines related to brains lesions and neurological disabilities. PMID- 29168183 TI - Effectiveness of gastrostomy for improving nutritional status and quality of life in patients with epidermolysis bullosa: a systematic review. AB - Individuals with epidermolysis bullosa (EB) may present with a broad spectrum of growth impairment and multiorgan disorders, with compromised nutritional status and quality of life. The provision of nutrients through a gastrostomy tube may minimize EB-related malnourishment but may also result in skin injuries and infections. In this systematic review we consider the current evidence about the effectiveness of gastrostomy in restoring nutritional status and improving quality of life in patients with EB. Seven studies (n = 146) met selection criteria and patients ranged in age from 6 weeks to 33 years of age. Although it is not a risk-free procedure, the placement of a gastrostomy tube is a feasible and safe alternative to provide nutritional support and to improve the quality of life of patients. PMID- 29168184 TI - Effect of ultra-superheated steam on aflatoxin reduction and roasted peanut properties. AB - BACKGROUND: Aflatoxins are carcinogenic toxins produced by Aspergillus flavus and Aspergillus parasiticus that are found naturally in peanut. It requires extremely high temperatures to eliminate aflatoxins from the nuts. The aims of this study were to investigate the effect of ultra-superheated steam (USS) on the reduction of aflatoxin B1 (AFB1 ) accompanying the roasting process and to determine roasted peanut qualities that affected consumer acceptance. RESULTS: Whole peanut kernels were intentionally contaminated by AFB1 standard solution at the level of 50 +/- 10 ug kg-1 before subjecting to USS treatment at 300-400 degrees C between 10 and 80 s. The high temperature of USS could significantly decrease AFB1 level to 9.83 +/- 3.51, 15.33 +/- 2.23 and 8.95 +/- 2.32 ug kg-1 when 300 degrees C for 80 s, 350 degrees C for 40 s and 400 degrees C for 40 s were employed, respectively. AFB1 was reduced as much as 83.86 +/- 2.66% when 400 degrees C for 40 s was applied. The moisture content of treated peanuts was decreased to less than 3% and browning index was developed from 30.96 +/- 1.59 to 95.76 +/- 7.23. CONCLUSION: Higher roasting degree was obtained according to the increase in browning index. Oil quality showed that peroxide values and acid values were greatly below the allowance level. USS could effectively decrease AFB1 and render expectable roasting qualities of peanut. (c) 2017 Society of Chemical Industry. PMID- 29168185 TI - YY1 suppresses proliferation and migration of pancreatic ductal adenocarcinoma by regulating the CDKN3/MdM2/P53/P21 signaling pathway. AB - Pancreatic ductal adenocarcinoma (PDAC) is one of the malignant lethal tumors. It has been reported that the transcriptional regulator Yin Yang-1 (YY1) suppressed the invasion and metastasis of PDAC. However, the function of YY1 on proliferation and migration of pancreatic cancer remains to be clarified. In this study, we found that YY1 overexpression or knockdown can inhibit or promote the proliferation and migration of pancreatic cancer cells. Digital gene expression sequencing indicates that cyclin-dependent kinase inhibitor 3 (CDKN3) may be the candidate target gene of YY1. Then we found that YY1 can downregulate the expression of CDKN3 by directly binding to the promoter region of CDKN3. Silencing CDKN3 expression could inhibit the ability of cell proliferation and migration and overexpression of CDKN3 could restore the effects induced by YY1 overexpression in pancreatic cancer cells. The expression levels of YY1 and CDKN3 were negatively correlated in pancreatic cancer tissues and PDAC patients with higher levels of CDKN3 have poor prognosis. Vitro and vivo study show that CDKN3 can form a complex with MdM2-P53, thus leading to inhibiting the expression of P21, which is the target gene of P53, and finally facilitates the cell cycle to promote the proliferation of pancreatic cancer cells. Hence, YY1 can directly regulate the expression of CDKN3 and participate in the cycle of pancreatic cancer cells, which can inhibit the progression of pancreatic cancer. These results reveal that YY1-CDKN3-MDM2/P53-P21 axis is involved in pancreatic tumorigenesis, which may develop new methods for human pancreatic cancer therapy. PMID- 29168187 TI - Storage time of platelet concentrates and risk of a positive blood culture: a nationwide cohort study. AB - BACKGROUND: Concern of transfusion-transmitted bacterial infections has been the major hurdle to extend shelf life of platelet (PLT) concentrates. We aimed to investigate the association between storage time and risk of positive blood cultures at different times after transfusion. STUDY DESIGN AND METHODS: We performed a nationwide cohort study among PLT transfusion recipients in Denmark between 2010 and 2012, as recorded in the Scandinavian Donations and Transfusions (SCANDAT2) database. Linking with a nationwide database on blood cultures (MiBa), we compared the incidence of a positive blood culture among recipients of PLTs stored 6 to 7 days (old) to those receiving fresh PLTs (1-5 days), using Poisson regression models. We considered cumulative exposures in windows of 1, 3, 5, and 7 days. RESULTS: A total of 9776 patients received 66,101 PLT transfusions. The incidence rate ratio (IRR) of a positive blood culture the day after transfusion of at least one old PLT concentrate was 0.77 (95% confidence interval [CI], 0.54 1.09) compared to transfusion of fresh PLT concentrates. The incidence rate of a positive blood culture was lower the day after receiving one old compared to one fresh PLT concentrate (IRR, 0.57; 95% CI, 0.37-0.87). Three, 5, or 7 days after transfusion, storage time was not associated with the risk of a positive blood culture. CONCLUSION: Storage of buffy coat-derived PLT concentrates in PAS-C up to 7 days seems safe regarding the risk of a positive blood culture. If anything, transfusion of a single old PLT concentrate may decrease this risk the following day. PMID- 29168188 TI - The relationship between social play and developmental milestones in wild chimpanzees (Pan troglodytes schweinfurthii). AB - Social play is common among many group-living animals, but the benefits are not well understood. Proposed benefits include increased muscle coordination as the result of increased locomotor versatility and development, and strengthened social bonds through interactions with like-aged individuals. In this study, we used 33 years of long-term behavioral data on infant chimpanzees in Gombe National Park, Tanzania, to examine these potential benefits of social play, specifically how the percentage of time engaged in social play relates to motor and social developmental milestones. We predicted that infants who engaged in more social play would achieve motor and social milestones at younger ages. We found that individuals that spent more time engaging in social play achieved the motor milestones of riding dorsally and traveling independently at earlier ages. Additionally, we found that the amount of play was correlated with earlier ages for reaching the social milestones of spatial independence from mother, first grooming of non-maternal kin, and first observed mating attempt. This is the first study in great apes to demonstrate a relationship between play behavior and developmental milestones, supporting the hypotheses that play provides motor, and social benefits. PMID- 29168186 TI - Adipokines and inflammation markers and risk of differentiated thyroid carcinoma: The EPIC study. AB - Other than the influence of ionizing radiation and benign thyroid disease, little is known about the risk factors for differentiated thyroid cancer (TC) which is an increasing common cancer worldwide. Consistent evidence shows that body mass is positively associated with TC risk. As excess weight is a state of chronic inflammation, we investigated the relationship between concentrations of leptin, adiponectin, C-reactive protein, interleukin (IL)-6, IL-10 and tumor necrosis factor (TNF)-alpha and the risk of TC. A case-control study was nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) study and included 475 first primary incident TC cases (399 women and 76 men) and 1,016 matched cancer-free cohort participants. Biomarkers were measured in serum samples using validated and highly sensitive commercially available immunoassays. Odds ratios (ORs) of TC by levels of each biomarker were estimated using conditional logistic regression models, adjusting for BMI and alcohol consumption. Adiponectin was inversely associated with TC risk among women (ORT3vs.T1 = 0.69, 95% CI: 0.49-0.98, Ptrend = 0.04) but not among men (ORT3vs.T1 = 1.36, 95% CI: 0.67-2.76, Ptrend = 0.37). Increasing levels of IL 10 were positively associated with TC risk in both genders and significantly so in women (ORT3vs.T1 = 1.59, 95% CI: 1.13-2.25, Ptrend = 0.01) but not in men (ORT3vs.T1 = 1.78, 95% CI: 0.80-3.98, Ptrend = 0.17). Leptin, CRP, IL-6 and TNF alpha were not associated with TC risk in either gender. These results indicate a positive association of TC risk with IL-10 and a negative association with adiponectin that is probably restricted to women. Inflammation may play a role in TC in combination with or independently of excess weight. PMID- 29168189 TI - Imaging mass spectrometry for novel insights into contact allergy - a proof-of concept study on nickel. AB - BACKGROUND: In spite of extensive regulation to limit exposure, nickel remains the main cause of contact allergy in the general population. More detailed knowledge on the skin uptake of haptens is required. So far, no method exists for the visualization of this clinically relevant hapten and its distribution in the skin. OBJECTIVES: To show, in terms of a proof of concept, that imaging mass spectrometry [time of flight secondary ion mass spectrometry (ToF-SIMS)] can be applied for investigation of the penetration and distribution of nickel in human skin. METHOD: Full-thickness human skin obtained from breast reduction surgery was exposed to nickel sulfate (5% in deionized water) for 24 h in Franz-type diffusion cells. Biopsies were obtained from nickel-treated samples and control (deionized water). The tissue was sliced, and analysed with ToF-SIMS, generating high-resolution images of ion distribution in the epidermis and upper dermis. RESULTS: The skin layers could be discerned from the ToF-SIMS data, particularly on the basis of the collagen signal. Nickel ions were localized to the stratum corneum and upper epidermis. CONCLUSIONS: This is the first time that ToF-SIMS has been applied to trace the distribution of a hapten in human skin. Proof of principle was shown for nickel, and the technique can, in the future, be expanded for investigation of the skin distribution of clinically relevant sensitizers in general. PMID- 29168190 TI - Innovative food products for cancer patients: future directions. AB - One of the main challenges for cancer patients under treatment is to prevent and tackle malnutrition. The current clinical nutrition market offers different food supplements or oral nutritional support products (mainly milkshakes or modified texture products) for cancer patients under risk of malnutrition. However, it is worth mentioning that these products do not address the pleasure of eating, since they do not meet sensory requirements, such as taste and smell alterations, nor patients' food preferences, leading to a big impact on their quality of life (QOL). Still, controversy remains regarding the specific nutritional requirements for cancer patients during the disease. Several randomized controlled clinical trials yield opposite results when using different bioactive compounds such as omega-3 fatty acids or antioxidants in order to prevent malnutrition or improve QOL. The use of 'omics' technologies in oncology, such as membrane lipidomics, as a powerful tool to provide new insights for the understanding of diet and cancer and their interacting metabolic pathways, will be discussed. The better knowledge of specific requirements (nutrients, sensory parameters and food preferences) for cancer patients provides valuable information for the food industry in the design of customized food products capable of preventing malnutrition, alleviating symptoms and improving QOL.

AB - Intramuscular fat (IMF) content is a key aspect of pork quality. Elucidation of intramuscular adipocyte regulation mechanisms is important for improving IMF content. Intramuscular adipocytes are dispersed among muscle fibers, so they are inclined to be affected by muscle-derived factors. Interleukin-15 is a major muscle-secreted factor. In this study, the genetic and physiological impacts of IL15 on adipogenesis is investigated. The promoter region of IL15 was scanned by comparative sequencing using two DNA pools of high- and low-IMF individuals. Two SNPs, c.-342C>T (ss2137497757) and c.-334G>A (ss2137497756) (the translation start site is designated as +1), were identified with reverse allele distribution in these two groups. Genotyping by allele-specific PCR revealed that the two SNPs were completely linked. The IMF content of TA/TA individuals was lower than that for CG/CG ones, whereas the IL15 expression level was higher in T-A/T-A individuals. Luciferase assaying also revealed that the T-A haplotype promoter had higher transcription activity. Meanwhile, the effect of interleukin-15 on adipocyte differentiation was further assessed in vitro. Results showed that interleukin-15 suppressed preadipocyte proliferation in a dose-dependent manner. The cell cycle of preadipocytes was arrested, and apoptosis was induced. Oil Red O staining and triglyceride quantification indicated that adipocyte differentiation was also inhibited by interleukin-15. The mRNA levels of PPARG and FABP4 decreased markably upon interleukin-15 treatment. Taken together, we identified two completely linked SNPs in the porcine IL15 promoter region that could alter IL15 transcription activity. As interleukin-15 can inhibit porcine adipocyte differentiation, these promoter mutations could affect IMF deposition by producing differential levels of muscle-derived interleukin-15. PMID- 29168192 TI - Seeing it differently: self-reported description of vision loss in dry age related macular degeneration. AB - PURPOSE: A realistic description of visual symptoms associated with dry age related macular degeneration (AMD) is important for raising awareness of the condition and educating patients. This study aimed to develop a set of descriptors for dry AMD and examine the realism of images currently and frequently used to show visual symptoms of the condition. METHODS: Volunteers with dry AMD with a range of disease severity were given an eye examination and were asked to describe visual symptoms of their condition in a conversational interview. Participants were also asked to comment on a photograph typically used to portray the visual symptoms of AMD. Interviews were audio recorded, transcribed and subjected to content analysis. RESULTS: Twenty-nine participants were interviewed. Median (interquartile range [IQR]) age was 75 (70, 79) years. Median (IQR) binocular visual acuity (VA) and Pelli-Robson contrast sensitivity (CS) was 0.2 (0.18, 0.36) logMAR and 1.65 (1.50, 1.95) log CS respectively. Three, 17 and nine patients had early, intermediate and late (geographic atrophy, GA) AMD, respectively. The most frequently reported descriptor group was blur (n = 13) followed by missing (n = 10) and distortion (n = 7). We chose the most popular image used to portray the visual symptoms of dry AMD based on an internet search and showed this to 21 participants. Sixteen participants (76% [95% confidence interval 53-92%]), including three out of the seven people with geographic atrophy, unequivocally rejected the realism of the image. CONCLUSIONS: People with dry AMD use a wide range of descriptors for their visual experience. Visual symptoms of dry AMD as portrayed by commonly shown images were not the experience of most people in this study. PMID- 29168193 TI - The Effects of Long-Term Varenicline Administration on Ethanol and Sucrose Seeking and Self-Administration in Male P Rats. AB - BACKGROUND: Varenicline, a partial agonist at alpha4beta2 and full agonist at alpha7 nicotinic cholinergic receptors, is FDA-approved for treatment of smoking cessation and has been found to reduce alcohol craving in clinical populations. In rodents, varenicline decreases free-choice ethanol (EtOH) intake with somewhat mixed findings in operant paradigms that utilize a combined appetitive/consummatory response. METHODS: The present experiment utilized an operant paradigm that procedurally separates appetitive from consummatory responding and a "reward-blocking" approach (i.e., rats were able to consume EtOH during treatment) to better understand the efficacy of varenicline as a treatment for EtOH self-administration and subsequent EtOH seeking. Separate groups of EtOH and sucrose-reinforced alcohol-preferring, male P rats experienced alternating cycles of vehicle (2-week cycles) and varenicline (0.3, 1.0, and 2.0 mg/kg self administered in a gelatin preparation) treatment (3-week cycles) prior to daily sessions where a single lever press resulted in 20 minutes of reinforcer access. At the end of each cycle, a single extinction session assessed the seeking response in the absence of drug pretreatment. RESULTS: Varenicline dose dependently decreased EtOH intake. Sucrose intake was largely unaffected, with no overall treatment effects and only sporadic days where the medium and high dose differed from vehicle. Neither sucrose nor EtOH seeking was significantly decreased by varenicline, and there were no treatment effects on either lick or lever-press latency. Overall effect sizes were much greater for both drinking and seeking in the EtOH group as compared to the sucrose group. CONCLUSIONS: Varenicline effectively attenuates EtOH self-administration during treatment, but the experience with EtOH consumption while varenicline is "on board" is not sufficient to alter subsequent EtOH seeking. The overall pattern of findings indicates that varenicline blocks the rewarding properties of EtOH while not substituting for EtOH, that the nonspecific effects on an alternate reinforcer are negligible, and that blood levels of varenicline need to be maintained in order for treatment to remain effective. PMID- 29168194 TI - Retinal putative glial alterations: implication for glaucoma care. AB - PURPOSE: Gliosis-like retinal alterations, presumed to be activated retinal astrocytes and Muller cells (ARAM), have been reported to occur frequently in patients with glaucoma but rarely in controls. We investigated the association between glaucomatous abnormality and the presence, the extent of retinal region, and the spatial distribution, of hyperreflective retinal alterations on optical coherence tomography (OCT) en-face images, presumed to be ARAM. METHODS: Findings of hyperreflective structures, presumed to be ARAM, in the central retinal +/-24 degrees of OCT en-face images (acquired with the SPECTRALIS(r) OCT) were compared between 35 younger controls, 42 older controls and 38 patients with glaucoma. Presumed ARAM was defined as reflective structures on the en-face images other than retinal vasculature and retinal nerve fibre bundles. Chi-square tests were used to compare the proportion of younger controls vs older controls with presumed ARAM to investigate the effect of ageing, and the proportion of patients vs age-similar older controls with presumed ARAM to investigate the effect of disease. We also investigated the effect of glaucoma on the retinal area with presumed ARAM when it was present; we used an analysis of covariance (ancova) to compare the retinal area with hyperreflectivity in patients vs controls, adjusting for the effects of age and axial length. RESULTS: The mean (S.D.) age of the younger controls, older controls, and patients with glaucoma was 26 (3), 62 (10) and 69 (8) years, respectively. The median (25th quartile, 75th quartile) of the retinal region with the hyperreflective structures, presumed to be ARAM, was zero (0,0), 1 (0,6), and 11 (0,43) degrees square in the younger controls, older controls and patients with glaucoma respectively. The chi-square test investigating the effect of ageing found chi2 (1, N = 77) = 24.8, p < 0.001, and that investigating the effect of disease found chi2 (1, N = 80) = 2.3, p = 0.1. The ancova found F(1, 46) = 10.32, P = 0.02. CONCLUSIONS: There was an effect of ageing on the presence of the hyperreflective structures, presumed to be ARAM, on OCT images. Compared to the presence of hyperreflective structures, the extent of retinal region with the hyperreflective structures has a greater potential of being an indicator of glaucomatous degeneration. Further study is needed to investigate the nature of the relation between glaucomatous abnormality and the extent of the retina with the hyperreflective structures, presumed to be ARAM. PMID- 29168195 TI - For whom we forgive matters: relationship focus magnifies, but self-focus buffers against the negative effects of forgiving an exploitative partner. AB - Increasingly, studies indicate that victims experience negative outcomes after forgiving offenders who present an exploitation risk. However, we demonstrate that the link between exploitation risk and forgiveness-related outcomes is dependent upon a victim's focus of forgiving. Two studies, the first employing a prospective design (N = 110) and the second an experimental scenario method (N = 261), replicate previous research on the negative effects of exploitation risk and also test two new hypotheses. First, we found that forgiving explicitly for the sake of a relationship is associated with greater distress, relative to deciding to forgive for the sake of the self. Second, we found that relationship focussed forgiveness magnified the distress caused by exploitation risk, whereas self-focussed forgiveness, relative to relationship-focussed forgiveness, provides a buffer against it. In short, these findings demonstrate that for whom we forgive matters. We discuss theoretical and practical implications for understanding when forgiving is costly. PMID- 29168196 TI - Family members' expectations regarding nurses' competence in care homes: a qualitative interview study. AB - BACKGROUND: Structural and cultural changes in the care of older people have influenced nursing practice, creating a need to identify current competency requirements for nurses working in care homes. Family members have an important role in ensuring the well-being of older people living in care homes, and family members' can provide valuable information about competence requirements. AIM: To explore the expectations of the care home residents' family members regarding the competence of nurses in care homes for older people. METHODS: A qualitative descriptive design was used. Semi-structured interviews were conducted with 18 care home residents' family members between March and September 2016. Participants were recruited with help from regional associations and member associations of The Central Association of Carers in Finland and from regional associations of The Alzheimer's Society of Finland. The snowball technique was also used. The data were analysed using inductive content analysis. ETHICS: Ethics committee approval was obtained from the university committee on research ethics, and written informed consent was obtained from participants. FINDINGS: The care home residents' family members expected that nurses would be able to interact with and treat people respectfully. Reflective collaboration between the nurse and a family member was also emphasised. Family members expected nurses to provide high-quality basic care and nursing and support residents' well-being individually and holistically. CONCLUSIONS: Family members' expectations reflect the need for ethical and interactional competence in the care home. In addition, evidence-based practice competencies are required to provide high-quality care. Nurses' ability to provide person-centred, individual and holistic care is vital to ensure care home residents' well-being. PMID- 29168197 TI - Mechanism of increased microbial autofluorescence by heat treatment. AB - : The total direct count (TDC) microbial enumeration method is rapid and suitable for analysing environmental samples containing numerous un-culturable micro organisms. Conventional TDC methods require the addition of a fluorescent stain and are thus unsuitable for automatic monitoring. We unexpectedly found that heated micro-organisms emit strong autofluorescence. This study was conducted to determine how heating enhances the autofluorescence of bacteria and fungi and to evaluate whether the phenomenon could be exploited to develop a new TDC method. Bacterial autofluorescence was augmented by heating cells at 200 degrees C. ELISA results indicated that levels of advanced glycation end products (AGEs) increased in heated microbes. Catechin, an inhibitor of the Maillard reaction, disrupted the intensification of autofluorescence. These results suggest that the enhanced autofluorescence is associated with the formation of AGEs and that the reaction could be utilized as alternative probe in TDC methods. SIGNIFICANCE AND IMPACT OF THE STUDY: Autofluorescence of bacteria and fungi was prominently intensified by heat treatment at 200 degrees C. This phenomenon was associated with advanced glycation end products formed in micro-organisms via the Maillard reaction. The fluorescence signal was strong enough to be utilized as an alternative probe for fluorescent dye in the total direct count method. This phenomenon could be incorporated in an automatic apparatus for microbial enumeration, as it does not require staining. PMID- 29168198 TI - PERK leads a hub dictating pancreatic beta cell homoeostasis. AB - In humans, the pathogenesis of diabetes is characterised by two major pancreatic beta cell defects: a reduction in beta cell mass and the failure of beta cells to produce enough insulin. Over the past two decades, multiple studies involving cell cultures, animal models and human subjects have established the importance of the protein kinase RNA-like endoplasmic reticulum kinase (PERK) in the adaptive functional capacity of pancreatic beta cells during embryonic development and into adulthood. In this review, we will highlight major findings identifying PERK as a crucial player in beta cell physiology and in diabetes. PMID- 29168199 TI - Experimental Investigation of Left Ventricular Flow Patterns After Percutaneous Edge-to-Edge Mitral Valve Repair. AB - Mitral valve percutaneous edge-to-edge repair (PEtER) is a viable solution in high-risk patients with severe symptomatic mitral regurgitation. However, the generated double-orifice configuration poses challenges for the evaluation of the hemodynamic performance of the mitral valve and may alter flow patterns in the left ventricle (LV) during diastole. This in vitro study aims to evaluate the hemodynamic modifications following a simulated PEtER. A custom-made mitral valve was developed, and two configurations were tested: (i) a single-orifice valve with mitral regurgitation and (ii) a double-orifice mitral valve configuration following PEtER. The hemodynamic performance of the valve was evaluated using Doppler echocardiography and catheterization, while the flow patterns in the LV were investigated using particle image velocimetry (PIV). The tests were run at a stroke volume of 65 mL and a heart rate of 70 bpm. PEtER was found to significantly reduce the regurgitant volume (15 vs. 34 mL). There was a good agreement between Doppler and catheter transmitral pressure gradients (peak gradient: 9 vs. 7 mm Hg; mean gradient: 4 vs. 3 mm Hg) as well as an excellent agreement between maximal velocity measured by Doppler and PIV (1.60 vs. 1.58 m/s). Vortex development in the LV during diastole was significantly different after repair. PEtER significantly increased the amplitude of Reynolds and viscous shear stresses, as well as the number of high shear regions in the LV, potentially promoting thromboembolism events. PMID- 29168200 TI - The moderating role of job resources in the relationship between job demands and interleukin-6 in an Italian healthcare organization. AB - In this study we examined the association between job demands (JD), job resources (JR), and serum levels of a possible biomarker of stress, the pro-inflammatory cytokine interleukin-6 (IL-6). According to the buffer hypothesis of the Job Demands-Resources (JD-R) model, we expected that job resources-defined as job autonomy and social support from supervisor-might buffer the relationship between job demands, defined as emotional demands and interpersonal conflict with colleagues, and IL-6. Data from 119 employees in an Italian public healthcare organization (acute care hospital) were analyzed using multiple regression. In predicting IL-6, the interactions between emotional demands and JR and between interpersonal conflict with colleagues and job autonomy (but not social support) were significant, after controlling for the effect of age and gender. The association between JD and IL-6 was stronger for individuals with low levels of JR, so that levels of IL-6 were highest when JD were high and JR were low. Overall, these results are consistent with the buffer hypothesis of the JD-R model and also extend previous research, showing that the exposure to stressful situations at work, measured as high JD and low JR, is associated with higher levels of IL-6 in hospital employees. PMID- 29168201 TI - Modification of pomological characteristics and flavour components of fruits and virgin olive oil following wastewater irrigation and soil tillage. AB - BACKGROUND: The experiment was carried out on olive trees cv. Chemlali, during two successive years (2013/2014). Two irrigation treatments (IT: Trees irrigated with wastewater; TRC: Trees grown under rainfed condition) were combined with two tillage practices (TTS: Trees grown in tilled soil; TNTS: Trees grown in non tilled soil). RESULTS: The results of the study showed that wastewater irrigation combined with soil tillage improved the pomological characteristics of olive fruits. The tree yield increase was substantial for IT and TTS. However, most of the identified phenolic compounds, especially oleuropein, mainly accumulated in olive fruits of the TC block (TNTS + TRC), suggesting a marked improvement in the nutritional value of these fruits. Moreover, fruits of TNTS had high contents of sugar compounds, required for the synthesis of the fruit storage material. The study also showed that the agronomic practices affected the amounts of some aromatic compounds responsible for the distinctive flavour notes of olive oil. CONCLUSION: Agronomic practices may affect considerably the commercial and nutritional values and the sensorial quality of the commodities. (c) 2017 Society of Chemical Industry. PMID- 29168202 TI - Differentiation of Ecuadorian National and CCN-51 cocoa beans and their mixtures by computer vision. AB - BACKGROUND: Ecuador exports two major types of cocoa beans, the highly regarded and lucrative National, known for its fine aroma, and the CCN-51 clone type, used in bulk for mass chocolate products. In order to discourage exportation of National cocoa adulterated with CCN-51, a fast and objective methodology for distinguishing between the two types of cocoa beans is needed. RESULTS: This study reports a methodology based on computer vision, which makes it possible to recognize these beans and determine the percentage of their mixture. The methodology was challenged with 336 samples of National cocoa and 127 of CCN-51. By excluding the samples with a low fermentation level and white beans, the model discriminated with a precision higher than 98%. The model was also able to identify and quantify adulterations in 75 export batches of National cocoa and separate out poorly fermented beans. CONCLUSION: A scientifically reliable methodology able to discriminate between Ecuadorian National and CCN-51 cocoa beans and their mixtures was successfully developed.

PMID- 29168203 TI - The Wisdom of Networks: A General Adaptation and Learning Mechanism of Complex Systems: The Network Core Triggers Fast Responses to Known Stimuli; Innovations Require the Slow Network Periphery and Are Encoded by Core-Remodeling. AB - I hypothesize that re-occurring prior experience of complex systems mobilizes a fast response, whose attractor is encoded by their strongly connected network core. In contrast, responses to novel stimuli are often slow and require the weakly connected network periphery. Upon repeated stimulus, peripheral network nodes remodel the network core that encodes the attractor of the new response. This "core-periphery learning" theory reviews and generalizes the heretofore fragmented knowledge on attractor formation by neural networks, periphery-driven innovation, and a number of recent reports on the adaptation of protein, neuronal, and social networks. The core-periphery learning theory may increase our understanding of signaling, memory formation, information encoding and decision-making processes. Moreover, the power of network periphery-related "wisdom of crowds" inventing creative, novel responses indicates that deliberative democracy is a slow yet efficient learning strategy developed as the success of a billion-year evolution.

PMID- 29168204 TI - Early and medium-term outcomes of Alfieri mitral valve repair in the management of systolic anterior motion during septal myectomy. AB - BACKGROUND: This report studies the early and medium-term clinical and echocardiographic outcomes of the Alfieri edge-to-edge mitral valve repair, as adjunctive therapy, to prevent and treat systolic anterior motion (SAM) at the time of septal myectomy (SM) for left ventricular outflow tract obstruction in hypertrophic cardiomyopathy. METHODS: From 2009-2015, 11 consecutive patients had a trans-atrial Alfieri repair, to prevent (n = 7) or treat (n = 4) SAM at the time of SM. RESULTS: No patients were lost to follow-up. There were no perioperative or late deaths. Pre-bypass, the mean left ventricular outflow tract gradient, measured directly by simultaneous needle insertion, was 40.7 +/- 19.9 mmHg at rest and 115.8 +/- 30.4 mmHg on provocation with Isoproterenol, which reduced after SM and Alfieri repair and discontinuation of bypass, to a mean gradient of 8.3 +/- 9.8 mmHg at rest and 25.8 +/- 9.2 mmHg on provocation. One patient who required mitral valve replacement on day 4, was hospitalized at 2.7 years with heart failure requiring diuresis and remains well at 6 years. One patient developed postoperative atrial fibrillation. There were no other early or late complications. At a median follow-up of 6.6 years (international quartile range 1.2-7.4), clinical and echocardiographic data demonstrated maintained improvement in mean New York Heart Association class from 2.6 +/- 0.9 preoperatively to 1.7 +/- 0.4 and reduction in mean grade of mitral regurgitation from 2.7 +/- 0.8 preoperatively to 0.7 +/- 0.6. CONCLUSIONS: The Alfieri repair, as adjunctive therapy, for the prevention or treatment of SAM at the time of SM demonstrates satisfactory early and medium-term clinical and echocardiographic outcomes supporting the ongoing utility of this approach.

AB - AIMS: GSK3191607, a novel inhibitor of the Plasmodium falciparum ATP4 (PfATP4) pathway, is being considered for development in humans. However, a key problem encountered during the preclinical evaluation of the compound was its inconsistent pharmacokinetic (PK) profile across preclinical species (mouse, rat and dog), which prevented reliable prediction of PK parameters in humans and precluded a well-founded assessment of the potential for clinical development of the compound. Therefore, an open-label microdose (100 MUg, six subjects) first time in humans study was conducted to assess the human PK of GSK3191607 following intravenous administration of [14C]-GSK3191607. METHODS: A human microdose study was conducted to investigate the clinical PK of GSK3191607 and enable a Go/No Go decision on further progression of the compound. The PK disposition parameters estimated from the microdose study, combined with preclinical in vitro and in vivo pharmacodynamic parameters, were all used to estimate the potential efficacy of various oral dosing regimens in humans. RESULTS: The PK profile, based on the microdose data, demonstrated a half-life (~17 h) similar to other antimalarial compounds currently in clinical development. However, combining the microdose data with the pharmacodynamic data provided results that do not support further clinical development of the compound for a single dose cure. CONCLUSIONS: The information generated by this study provides a basis for predicting the expected oral PK profiles of GSK3191607 in man and supports decisions on the future clinical development of the compound. PMID- 29168207 TI - Abnormalities in interactions of Rho GTPases with scaffolding proteins contribute to neurodevelopmental disorders. AB - Accumulating evidence suggests that Rho GTPases, together with scaffolding SHANK proteins, and associated signaling pathways play a role in the development of autism symptoms in various conditions. Research data have brought information on multiple intracellular signaling pathways, including Rho-associated protein kinases and serine/threonine-protein kinases involved in cytoskeleton rearranging. Alterations in downstream effectors of GTPase signaling pathways are associated with neurodevelopmental disorders. Bioinformatics and experimental data show that complex genetic and molecular defects (GTPases, actin-binding proteins, kinases, neuropeptides) can result in neuronal remodeling, leading to the functional connectivity deficits that manifest as the heterogeneous autism spectrum phenotype. Finally, the known hormone and neuropeptide oxytocin appears to be a factor for consideration in therapeutic intervention. PMID- 29168208 TI - Unusual subcutaneous invasion of myxoid liposarcoma.

AB - BACKGROUND: Excessive catecholamine leads to pressure overload and left ventricular (LV) remodeling. The goal of this study was to explore subclinical LV systolic dysfunction and the mechanism of preserved left ventricular ejection fraction (LVEF) in patients with pheochromocytoma and paraganglioma using two dimensional speckle tracking echocardiography. METHODS: A total of 48 patients with pheochromocytoma and paraganglioma and preserved LVEF and 38 age- and gender matched volunteers were studied. Echocardiographic parameters including LVEF, and global peak longitudinal and circumferential strains were measured. The correlation between echocardiographic parameters and blood pressure as well as biochemical parameters was analyzed. RESULTS: LVEF was similar between patients with pheochromocytoma and paraganglioma and controls. The amplitude of LV longitudinal strain was decreased, and the amplitude of LV circumferential strain was increased in the pheochromocytoma and paraganglioma group (P = .003 and P = .009). LV mass index and blood pressure were positively correlated with 24-hour urinary norepinephrine (r = .696, P < .0001; r = .470, P = .0007). The amplitude of LV longitudinal strain reduced with increase in blood pressure, 24-hour urinary norepinephrine and LV mass index (r = -.305, P = .035; r = -.506, P = .0002; r = -.680, P < .0001). CONCLUSIONS: This study revealed that excessive norepinephrine in pheochromocytoma and paraganglioma was associated with increased blood pressure and LV mass. The LV longitudinal strain was decreasing with increase in blood pressure and LV mass index. The enhanced LV circumferential strain might be the mechanism of compensation to maintain the normal LVEF in these patients. PMID- 29168210 TI - Abrupt generalized pustules in patients with rheumatoid arthritis and interstitial lung disease. AB - We report a case of a 30-year-old Chinese woman with rheumatoid arthritis and interstitial lung disease who abruptly developed generalized pustules and a high fever for 10 days. She had been taking oral prednisone, iguratimod and total glucosides of peony regularly for 5 months prior. In addition, she had taken metronidazole for 3 days 20 days prior which she had used before with no adverse reaction. She had no history of similar lesions and psoriasis. A biopsy of a pustule on the back showed spongiform pustule of Kogoj. She was suspected of having generalized pustular psoriasis or acute generalized exanthematous pustulosis. Finally, she was diagnosed with generalized pustular psoriasis (von Zumbusch type) considering the characteristics and clinical course of the rash. In addition to the above three drugs, systemic cyclosporin (5 mg/kg per day) was applied, and the lesions and fever resolved within the proceeding 2 months. PMID- 29168211 TI - Factors associated with medication administration errors and why nurses fail to report them. AB - BACKGROUND: Patient safety is a significant challenge facing healthcare systems. The administration of medication is pivotal to patient safety, and errors in drug administration are associated with mortality and morbidity. In this study, we assessed the factors contributing to the occurrence and reporting of medication errors from the nurse's perspective. METHODS: In this descriptive cross-sectional study, we distributed a validated questionnaire to 367 nurses at a large public hospital and obtained a response rate of 73.4%. The questionnaire comprised 65 questions, including 29 on the causes of medication errors, 16 on the reasons why medication errors are not reported and 20 that estimated the percentages of the different medication errors actually reported. Informed consent was obtained from all participants, and the anonymity and confidentiality of participants' information were preserved throughout the process. This study received institutional review board approval. Descriptive statistics were used for data analysis. RESULTS: The main factors associated with medication errors by nurses were related to medication packaging, nurse-physician communication, pharmacy processes, nurse staffing and transcribing issues. The main barriers to the reporting of errors by nurses were related to the administrative response, fear of reporting and disagreements regarding the definitions of errors. CONCLUSION: Medication errors by nurses are related to medication packaging, poor communication, unclear medication orders, workload and staff rotation. To prevent medication errors, teamwork must be improved. All healthcare settings should emphasise awareness of the culture of safety, provide support and guidance to nurses and improve communication skills. We also recommend the use of integrated health informatics, including computerised drug administration systems. The limitations of this study include the potential for nonresponse bias associated with the sampling method. Further research is required to explore the complex and multidimensional causes of medication errors and review the responses of nurses regarding the errors reported.

PMID- 29168213 TI - Economic assessment of actual prescription of drugs for treatment of atopic dermatitis: Differences between dermatology and pediatrics in large-scale receipt data. AB - Using large-scale receipt data, we analyzed the differences in the prescription of drugs and their costs between dermatology and pediatrics in the treatment of atopic dermatitis (AD) in children. Between August 2010 and July 2011, 50 706 patients were diagnosed as having AD, and the data of 21 075 (15 257 dermatology, 5818 pediatric) patients aged 0-14 years were included in this study. The use of classes I (strongest), II (very strong), and III (strong) topical corticosteroids and tacrolimus was significantly higher in dermatology than in pediatrics (class I, 2.88% vs 0.76%; class II, 27.68% vs 8.32%; class III, 52.53% vs 39.88%; tacrolimus, 5.05% vs 2.82%; all P < 0.05). Although total drug costs were higher in dermatology than in pediatrics, mean drug costs per person were significantly higher in pediatrics. Moisturizers and protective agents had the highest cost (~ Y690 million). The introduction rate of generic drugs was low at 8.3% among classes I-V. The introduction rate of moisturizers and protective agents, for which costs were the highest, was approximately 9%. The prescription of generic classes II-V topical corticosteroids and moisturizers and protective agents was also significantly higher in dermatology than in pediatrics (P < 0.05). Among patients younger than 2 years, 4405 received drugs for AD; classes I and II topical corticosteroids and tacrolimus (against the guidelines) were administrated in 35 (0.8%), 474 (10.8%) and 29 patients (0.7%), respectively. The introduction of generic drugs is still low, and the use of generic moisturizers and protective agents should be addressed further. PMID- 29168214 TI - Transdermal light neuromodulation: Optogenetics in the murine urinary tract. AB - BACKGROUND: Optogenetics is a biologic technique that uses light to control living neurons, which have been genetically modified to express light-sensitive ion-channels. OBJECTIVES: Using an adenovirus to modify the sciatic nerves of mice, we aim to demonstrate peripheral neuromodulation of bladder pain using transdermal light. STUDY DESIGN: This pilot study is divided into: A) Confirmation and Application and B) Behavioral Step. A) Six mice were injected with AAV6-hSyn-ChR2(H134R)-eYFP virus into their sciatic nerves. This encoded an excitatory opsin, enabling light-inducible stimulation. At 4-6 weeks after injection, we induced foot pain responses with an activating blue 475 nm wavelength of light. B) Two optogenetically primed mice and two control mice underwent anesthesia and capsaicin was instilled into their bladders via catheter. The catheters were removed and the mice awoke in a chamber that exposed them to either blue 475 nm light or no light. Groin licking was scored in a binary fashion by two blinded observers. RESULTS: A) All six mice exhibited pain response to 475 nm blue light either by licking of foot or avoidance of light. B) The optogenetically primed mice had a 48% reduction in bladder pain behavior when exposed to blue 475 nm light whereas the control mice had a 18% reduction. CONCLUSION: To our knowledge this is the first demonstration of the application of optogenetics to modulate sensation in the lower urinary tract. It suggests that the process of priming peripheral nerves for optogenetic modulation is possible and can be used to study bladder pain response in mice. PMID- 29168215 TI - Non-corticosteroid adherence and itch severity influence perception of itch in atopic dermatitis. AB - Topical corticosteroid phobia is an important problem in the treatment of atopic dermatitis as it can affect the ability to control disease severity and itch by reducing treatment adherence. Topical corticosteroid phobia often ends up even non-corticosteroid adherence. As such, non-corticosteroid adherence, disease severity and itch are likely to be associated with each other, but their relationship has yet to be thoroughly investigated. Thus, the purpose of this study is to investigate it in atopic dermatitis. Using data from 1190 participants in an Internet survey, we identified 255 non-corticosteroid users and 225 with moderate to severe itch who were defined as non-corticosteroid adherents. Corticosteroid users with the same itch categories (n = 878) served as controls. We also examined how itch severity affects the perception of itch in atopic dermatitis. Unexpectedly, non-corticosteroid adherents were less sensitive to the conditions to elicit itch such as perspiring, commuting homeward, drinking alcohol and wearing woolen clothes compared with the control. We also found that patients with severer itch were more sensitive to itch during/after bathing, when lying in bed, commuting homeward, studying/working, drinking alcohol, undressing, getting up in the morning, after a meal, ingesting piquant foods and when they were unoccupied, angry, busy, nervous, sad or enjoying themselves. In conclusion, we found that non-corticosteroid adherence and itch severity influence perception of itch in atopic dermatitis and discuss possible mechanisms underlying these results. The information obtained in this study may be useful for communication with and education of atopic dermatitis patients and their treatment in outpatient clinics. PMID- 29168216 TI - Understanding frames: A qualitative study of young people's experiences of using standing frames as part of postural management for cerebral palsy. AB - BACKGROUND: Consensus opinion supports standing frame use as part of postural management for nonambulant young people with cerebral palsy. Although the rationale for standing frame use and the associated challenges have been described, little attention has been given to the users' experiences. The aim of the current study was to explore young people's positive and negative experiences, and attitudes regarding standing frame use. METHODS: Framework analysis informed an open exploration of young people's opinions of standing frames. Using semistructured interviews, 12 young people with cerebral palsy (6 female) were interviewed, providing the data set for transcription and thematic analysis. FINDINGS: The first theme "attitudes to standing frames" describes the young people's understanding of why they use standing frames. Although standing frames can be painful, some young people believe they should be endured to improve their body structure and function. There were mixed views about the impact standing frames have socially, with some young people feeling excluded from their peers, and others feeling as though standing frames helped them "fit in." Some young people are not offered a choice about how and when they use their standing frame. The second theme "challenges of standing frame use" highlights the issues with standing frame use such as manual handling, interference from siblings, and the lack of aesthetically pleasing standing frame designs. CONCLUSIONS: Young people report benefits related to choice, pain relief, and participation but can also cause pain, discomfort, and reduced independence and participation. Healthcare professionals should have open, informative conversations about potential benefits and challenges of standing frames on all aspects of the young people's lives, including participation and activity. PMID- 29168217 TI - Prevalence, management, and prognosis of bladder cancer in patients with neurogenic bladder: A systematic review. AB - AIM: To perform a systematic review of the literature regarding epidemiology, diagnosis, management and prognosis of bladder cancer in the neuro-urological patient population, in order to serve as a basis for future recommendations and research. METHODS: A systematic review was performed according to the PRISMA Preferred Reporting Items for Systematic Reviews and Meta-Analyzes Statement. Embase was searched for studies providing data on epidemiology, diagnosis, management and prognosis of bladder cancer in neuro-urological patients. RESULTS: After screening 637 abstracts, 15 studies (13 retrospective and 2 prospective studies) were included in this study. We identified 332 patients (0.3%) who were diagnosed with bladder cancer. This mostly affected mostly men (59.3%) and spinal cord injured patients (98.8%). Mean age at diagnosis was 56.1 years. Bladder cancer occurred after a long period of evolution of the neurological disease (24.9 years). Gross hematuria was the predominating presenting symptom (31.6% of cases). Indwelling urethral or supra-pubic catheters were used in 44.5% of patients. The most frequent histological subtype of bladder cancer was transitional cell carcinoma (53.1%), followed by squamous cell carcinoma (33.5%). Muscle-invasive bladder cancer was reported in 67.7% of patients. The mean cancer specific mortality rate was of 47.1%. CONCLUSIONS: The prevalence and high mortality rate of bladder cancer in neuro-urological patients underlines the importance of long-term follow-up in this specific population. This highlights the necessity of further studies in this field. PMID- 29168218 TI - The clinical epidemiology of sickle cell anemia In Africa. AB - Sickle cell anemia (SCA) is the commonest severe monogenic disorders of humans. The disease has been highly characterized in high-income countries but not in sub Saharan Africa where SCA is most prevalent. We conducted a retrospective cohort study of all children 0-13 years admitted from within a defined study area to Kilifi County Hospital in Kenya over a five-year period. Children were genotyped for SCA retrospectively and incidence rates calculated with reference to population data. Overall, 576 of 18,873 (3.1%) admissions had SCA of whom the majority (399; 69.3%) were previously undiagnosed. The incidence of all-cause hospital admission was 57.2/100 person years of observation (PYO; 95%CI 52.6 62.1) in children with SCA and 3.7/100 PYO (95%CI 3.7-3.8) in those without SCA (IRR 15.3; 95%CI 14.1-16.6). Rates were higher for the majority of syndromic diagnoses at all ages beyond the neonatal period, being especially high for severe anemia (hemoglobin <50 g/L; IRR 58.8; 95%CI 50.3-68.7), stroke (IRR 486; 95%CI 68.4-3,450), bacteremia (IRR 23.4; 95%CI 17.4-31.4), and for bone (IRR 607; 95%CI 284-1,300), and joint (IRR 80.9; 95%CI 18.1-362) infections. The use of an algorithm based on just five clinical features would have identified approximately half of all SCA cases among hospital-admitted children with a number needed to test to identify each affected patient of only fourteen. Our study illustrates the clinical epidemiology of SCA in a malaria-endemic environment without specific interventions. The targeted testing of hospital admitted children using the Kilifi Algorithm provides a pragmatic approach to early diagnosis in high-prevalence countries where newborn screening is unavailable.

PMID- 29168222 TI - The prognostic significance of frailty compared to peak oxygen consumption and B type natriuretic peptide in patients with advanced heart failure. AB - Frailty assessment has become an integral part of the evaluation of potential candidates for heart transplantation and ventricular assist device (HTx/VAD). The impact of frailty, as a heart failure risk factor or to identify those who will derive the greatest benefit with HTx/VAD remains unclear. The aim of this study was to evaluate the independent prognostic relevance of frailty assessment from peak oxygen consumption (peak VO2 ) or B-type natriuretic peptide (BNP) on mortality in patients referred for advanced heart failure therapies. Frailty was measured using modified Fried frailty criteria. In 201 consecutive patients, during a median follow-up of 17.5 months (IQR 11-29.2), there were 25 (12.4%) deaths. One-year survival was 100%, 94%, and 78% in nonfrail, prefrail, and frail patients, respectively (log rank P = .0001). Frailty was associated with a twofold increase risk of death (HR 2.01, P < .0001, 95% CI 1.42-2.84). When adjusted for BNP or peak VO2 , frailty was not associated with a significant risk of all-cause death. However, when peak VO2 is stratified into two categories (>=12 mL/kg/min vs <12 mL/kg/min), frailty was associated with increased mortality in patients with a lower peak VO2 (HR 1.72, P = .006).

AB - Nations of the world have committed to a number of goals and targets to address global environmental challenges. Protected areas have for centuries been a key strategy in conservation and play a major role in addressing current challenges. The most important tool used to track progress on protected-area commitments is the World Database on Protected Areas (WDPA). Periodic assessments of the world's protected-area estate show steady growth over the last 2 decades. However, the current method, which uses the latest version of the WDPA, does not show the true dynamic nature of protected areas over time and does not provide information on sites removed from the WDPA. In reality, this method can only show growth or remain stable. We used GIS tools in an approach to assess protected-area change over time based on 12 temporally distinct versions of the WDPA that quantify area added and removed from the WDPA annually from 2004 to 2016. Both the narrative of continual growth of protected area and the counter-narrative of protected area removal were overly simplistic. The former because growth was almost entirely in the marine realm and the latter because some areas removed were reprotected in later years. On average 2.5 million km2 was added to the WDPA annually and 1.1 million km2 was removed. Reasons for the inclusion and removal of protected areas in the WDPA database were in part due to data-quality issues but also to on-the ground changes. To meet the 17% protected-area component of Aichi Biodiversity Target 11 by 2020, which stood at 14.7% in 2016, either the rate of protected area removal must decrease or the rate of protected-area designation and addition to the WDPA must increase. PMID- 29168225 TI - GABA-modulating phytomedicines for anxiety: A systematic review of preclinical and clinical evidence. AB - Anxiety disorders are chronic and functionally disabling conditions with high psychological stress, characterised by cognitive symptoms of excessive worry and focus difficulties and physiological symptoms such as muscle tension and insomnia. Gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter within the central nervous system and is a key target of pharmacotherapies in the treatment of anxiety. Although current pharmaceutical treatments are often efficacious, they may cause undesirable side effects including cognitive decrements and withdrawal symptoms. Plant-based "phytomedicines" may provide novel treatment options, to act as an adjunctive or alternative to existing anxiolytic medications. As such, we conducted a systematic review to assess the current body of literature on anxiolytic phytomedicines and/or phytoconstituents. An open-ended search to 5 July 2017 was conducted using MEDLINE (PubMed), Scopus, and Cochrane library online databases and performed in a stepped format from preclinical to clinical investigations. Eligible studies must have had (a) in vitro evidence of GABA-modulating activity, (b) animal studies using anxiety models to test an anxiolytic effect, and (c) human clinical trials. Ten phytomedicines were identified as having preclinical investigations showing interaction with the GABA system, in addition to human clinical trials: kava, valerian, pennywort, hops, chamomile, Ginkgo biloba, passionflower, ashwagandha, skullcap, and lemon balm. Collectively, the literature reveals preclinical and clinical evidence for various phytomedicines modulating GABA-pathways, with comparative anxiolytic effect to the current array of pharmaceuticals, along with good safety and tolerability profiles.

PMID- 29168227 TI - Alternatives to biodiversity offsets for mitigating the effects of urbanization on stream ecosystems. AB - Globally, offset schemes have emerged in many statutory frameworks relating to development activities, with the aim of balancing biodiversity conservation and development. Although the theory and use of biodiversity offsets in terrestrial environments is broadly documented, little attention has been paid to offsets in stream ecosystems. Here we examine the application of offset schemes to stream ecosystems and explore whether they suffer similar shortcomings to those of offset schemes focused on terrestrial biodiversity. To challenge the applicability of offsets further, we discuss typical trajectories of urban expansion and their cascading physical, chemical and biological impacts on stream ecosystems. We argue that the highly connected nature of stream ecosystems and urban drainage networks can transfer impacts of urbanization across wide areas, complicating the notion of like-for-like exchange and the prospect of effectively mitigating biodiversity loss. Instead, we identify in-catchment options for stormwater control, which can avoid or minimize the impacts of development on downstream ecosystems, while presenting additional public and private benefits. We describe the underlying principles of these alternatives, some of the challenges associated with their uptake, and policy initiatives being trialed to facilitate adoption. In conclusion, we argue that stronger policies to avoid and minimize the impacts of urbanization provide better prospects for protecting downstream ecosystems, and can additionally, stimulate economic opportunities and improve urban liveability. PMID- 29168228 TI - Trajectory of spirometric and exhaled nitric oxide measurements in Chinese schoolchildren with asthma. AB - BACKGROUND: Lung function growth occurs in most asthmatic children. A subgroup has subnormal lung function trajectory, but such data are limited in children. This prospective study characterized longitudinal changes of spirometric indices and fractional exhaled nitric oxide level (FeNO) among asthmatic children and identified their genetic and environmental determinants. METHODS: Chinese asthmatic children recruited from pediatric clinics underwent 5-year follow-up for pre-bronchodilator spirometric indices and FeNO. Fourteen asthma-associated single nucleotide polymorphisms (SNPs) were genotyped. Generalized estimating equation was used to analyze longitudinal changes of spirometric indices and FeNO. RESULTS: One hundred and ninety-three asthmatic children, aged 9.7 (1.9) years, had significant annual decline of 1.3% for forced vital capacity (FVC) and annual increase of 1.2% and 3.6% for FEV1 /FVC and FEF25-75 , respectively. Patients who received inhaled corticosteroid (ICS) had 2.4% lower baseline FEV1 /FVC but 0.81% higher annual increase in FEV1 . Body mass index (BMI) was associated inversely with FEV1 /FVC but positively with FEV1 % and FVC% changes. Asthma exacerbation was associated with lower FEV1 % and FVC% but not their longitudinal changes. When classified by FEV1 curve, one-quarter of patients had reduced lung function growth which was associated with female gender and lower spirometric and higher FeNO values at baseline. IL33_rs1342326 was associated with spirometric indices and FeNO, whereas GSDMB_rs2305480 was significantly associated with FEV1 /FVC change. CONCLUSION: Asthmatic children have annual decline in FVC and increase in FEV1 /FVC and FEF25-75 . Their lung function trajectory is influenced by gender, ICS treatment, BMI, and asthma exacerbations. IL33 and GSDMB may be candidate genes for their lung function growth.

PMID- 29168230 TI - Routine guidewire application facilitates cholangioscopy in the management of postoperative residual hepatolithiasis. AB - BACKGROUND AND AIM: Although postoperative cholangioscopy (POC) is considered to be an effective treatment for residual hepatolithiasis after surgery, its security and validity still need to be improved. This study compared wire-guided POC (WG-POC) versus traditional POC (T-POC) in the management of patients with residual hepatolithiasis. METHODS: This retrospective study included a total of 203 patients who suffered from hepatolithiasis and underwent hepatectomy as initial intervention from 1 January 2016 to 1 January 2017. After surgery, 110 patients were subjected to T-POC and 93 to WG-POC for eliminating residual hepatolithiasis. Perioperative course and follow-up outcomes were retrospectively analyzed. RESULTS: No significant differences in clinical characteristics or distribution of residual hepatolithiasis between the WG-POC and T-POC groups were observed (P > 0.05). However, overall POC interventional sessions (2.9 +/- 0.85 vs 4.0 +/- 1.21 times), average operating time (264.8 +/- 103.61 vs 389.4 +/- 136.26 min), overall complications rate (18.28% vs 32.73%), and overall T-tube retaining time (21.8 +/- 6.20 vs 28.8 +/- 8.09 days) were lower in the WG-POC group than in the T-POC group (P < 0.05). In addition, there were no significant differences between the two groups (WG-POC vs T-POC) in recurrence (4.30% vs 4.55%) and residual calculi (8.60% vs 6.36%) at half-a-year follow up (P > 0.05). CONCLUSIONS: Routine wire guidance may improve the outcome of cholangioscopy in managing complicated residual hepatolithiasis, being associated with clear advantages such as shorter operating time and number of POC interventions, reduced T-tube retaining time, and fewer postoperative complications. PMID- 29168231 TI - A new hybrid anchoring balloon for direct peroral cholangioscopy using an ultraslim upper endoscope. AB - BACKGROUND AND AIM: Large impacted or residual invisible common bile duct (CBD) stones after mechanical lithotripsy are challenging. We aimed to evaluate the feasibility and success rate of a new hybrid anchoring balloon-guided direct peroral cholangioscopy (POC) for these conditions using an ultraslim endoscope. METHODS: Sixty-five patients with large or residual invisible CBD stones for direct POC from July 2012 to July 2016 were identified, including six cases in whom an additional interventional procedure was required. There were altogether 55 cases undergoing a procedure with our new device, with a 0.021-inch guidewire tied to a balloon catheter at its distal end in this single-center retrospective study. Technical success, procedure time, diagnostic and therapeutic efficacy of direct POC, and procedure-related complications were studied. RESULTS: The hybrid anchoring balloon-guided direct POC was successful in 51/55 (92.7%) procedures, including 18 cases in whom the conventional wire-guided method failed within 25 min. Mean time for technical success by our method was 12.4 +/- 3.4 min. In total, of the 43 cases with previous removal of CBD stones, seven (16.3%) were found to have residual stones >=4 mm, excluding three cases in whom direct POC failed. In another 25 cases for difficult stones, 24 lithotripsies were carried out, resulting in 23 complete fragmentations. No significant procedure-related complications were observed. CONCLUSION: The new hybrid anchoring balloon device performs well in facilitating direct POC using an ultraslim endoscope for evaluation and extraction of residual or large impacted CBD stones.

AB - The history of pediatric allergology (PA) in Europe is relatively youthful, dating back to 1984, when a small group of pediatricians founded the European Working Group on Pediatric Allergy and Immunology-later giving rise to ESPACI (European Society on Pediatric Allergology and Clinical Immunology). In 1990, the first dedicated journal, Pediatric Allergy and Immunology (PAI), was founded. There are striking differences across Europe, and even within European countries, in relation to the training pathways for doctors seeing children with allergic disease(s). In 2016, the EAACIClemens von Pirquet Foundation (CvP) organized and sponsored a workshop with the European Academy of Allergy and Clinical Immunology (EAACI) Pediatric Section. This collaboration focussed on the future of PA and specifically on education, research, and networking/ advocacy. The delegates representing many countries across Europe have endorsed the concept that optimal care of children with allergic diseases is delivered by pediatricians who have received dedicated training in allergy, or allergists who have received dedicated training in pediatrics. In order to meet the needs of children and families with allergic disease(s), the pediatric allergist is highly encouraged to develop several networks. Our challenge is to reinforce a clear strategic approach to scientific excellence to across our member base and to ensure and enhance the relevance of European pediatric research in allergy. With research opportunities in basic, translational, clinical, and epidemiologic trials, more trainees and trained specialists are needed and it is an exciting time to be a pediatric allergologist. PMID- 29168234 TI - Impact of comorbidities constituting the hematopoietic cell transplant (HCT) comorbidity index on the outcome of patients undergoing allogeneic HCT for acute myeloid leukemia. AB - OBJECTIVE: To investigate the prognostic impact of the individual component comorbidities of the hematopoietic cell transplant comorbidity index (HCT-CI) in patients with acute myeloid leukemia (AML) that underwent allogeneic hematopoietic cell transplant (HCT). METHOD: This single-center study retrospectively investigated the individual comorbidities of the HCT-CI on the outcome of 418 patients that underwent HCT for AML, in CR1 (n = 303, 72%) or CR2 (n = 115, 28%) at our center between 1999 and 2014. RESULTS: Median age at HCT was 50 years (range 18-71). Univariate analysis of the HCT-CI, grouped as score 0 (n = 109), 1-2 (n = 157) and >=3 (n = 152), demonstrated significant influence on overall survival (OS) (P = .004) and non-relapse mortality (NRM) (P = .02). For individual comorbidities constituting the HCT-CI, variables with a P-value <= .2 on univariate analysis were included in the multivariable analysis. For OS, none of the comorbidities of the HCT-CI demonstrated independent prognostic relevance. However, for NRM, multivariable analysis demonstrated pretransplant diabetes (HR = 2.17, 95% CI = 1.31-3.60, P = .003) and cardiovascular comorbidity (HR = 1.78, 95% CI = 1.15-2.76, P = .01) to be independent predictors of NRM post-transplant. CONCLUSION: Among the comorbidities that compose the HCT-CI, diabetes and cardiovascular comorbidity independently predict NRM in patients undergoing allogeneic HCT for AML. This information should be taken into consideration regarding post-transplant monitoring and care. PMID- 29168235 TI - Effects of nutraceuticals on sexual satisfaction and lower urinary tract symptoms in a cohort of young-old men. AB - The aim of this study was to evaluate the effects of nutraceuticals containing multiple supplemental facts (Virherbe(r)/Rekupros(r)) on sexual satisfaction and lower urinary tract symptoms (LUTS) in young-old men. In an open-label trial, 40 males (mean age 66 +/- 13) with sexual disturbances and mild LUTS but without cognitive/motor impairment and clinical hypogonadism were enrolled. Sexual desire (SD; IIEF-SD domain) and satisfaction (Global Assessment Question; GAQ), the capacity to perform daily activities (evaluated by 6-min walking test [6MWT]), and International Prostate Symptoms Scores (IPSS) were evaluated before and after oral administration of 2 capsules/day of each supplement for 8 weeks. The difference from baseline for SD was +2.6 (p < .05) and -4.2 points for IPSS (p < .05), with significance in subscales of urinary streaming/nocturia (p < .01), respectively; 6MWT increased from 507 +/- 44 versus 527 +/- 58 meters (p < .001). GAQ scale-responses showed overall improvement in overall 75% population, with a significant improvement in QoL (p < .01). These changes returned to baseline at 1 month withdrawal follow-up. No adverse events were reported. These supplemental facts improved sexual desire, satisfaction with sex life, physical performance, and LUTS in young-old men, suggesting that they may be effective in patients in whom standard treatments are not suitable.

AB - Cord blood transplantation (CBT) is associated with delayed hematopoietic recovery and graft failure. To overcome these problems, we conducted a prospective, multicenter phase II study of intrabone marrow transplantation in which patients received reduced-intensity conditioning without anti-thymocyte globulin (ATG). The primary endpoint was the probability of full donor engraftment. Forty patients with hematologic malignancies were enrolled. Cord blood (CB) cells were injected without washing into 4 iliac bone sites (2 at each hemipelvis), at which approximately 6 mL of CB was administered at one site with local anesthesia. Full donor engraftment rate was 86.8%. The cumulative incidence of neutrophil and platelet engraftment was 86.4% and 85.5%, respectively. The median time to neutrophil (>0.5 * 109 /L) and platelet (2.0 * 109 /L) recovery was 17.5 and 44 days, respectively. The probability of severe acute graft-vs-host disease (GVHD) was 47.5%. The cumulative incidence of extensive chronic GVHD was 3.0%. The probability of relapse and non-relapse mortality was 30.4% and 28.0%, respectively. The survival rate at 3 years was 45.6%, although most patients were at an advanced stage. These results suggest that our intrabone marrow-CBT procedure without using ATG improves hematopoietic recovery and decreases the incidence of chronic GVHD, but does not decrease the incidence of acute GVHD.

AB - BACKGROUND: In spite of some evidence for positive effects of patient's education to asthma self-management by randomized clinical trials, there are few studies on the impact of patient' s educational programs in the real world. We aimed to assess the impact of a diagnostic therapeutic educational pathway (DTEP) on asthma control of children and adolescents by comparing frequency of outcomes indicative of asthma control before and after attending the pathway. METHODS: This is a retrospective cohort study including all patients aged 6-11 and 12-17 years who attended the DTEP in 2007-2014. The DTEP includes 3 specialist's evaluations at 8- to 12-week intervals and two follow-up visits. Patients and their parents receive an educational course concerning prevention measures, early recognition of symptoms, and appropriate use of drugs and devices. The rates of hospitalizations, outpatient services, emergency room visits, and drug prescriptions were considered as outcomes and computed as number of events divided by person-time. RESULTS: A total of 806 patients were enrolled. A statistically significant decrease in rates from before to after DTEP was observed for almost all outcomes, in both age groups, with relative risks ranging from 0.12 to 0.60. The rates of drug prescription showed a statistically significant decrease, from before to after DTEP, for each type of medicine for asthma, in both age groups, from percent difference of -66% to -24.3%. CONCLUSIONS: The positive impact of this program on the outcomes indicative of asthma control in both children and adolescents suggests that it may be valuable for asthma management. PMID- 29168240 TI - Citrus essential oils inhalation by mice: Behavioral testing, GCMS plasma analysis, corticosterone, and melatonin levels evaluation. AB - The use of orange essential oils (EOs) as a complementary treatment is very common in Brazilian popular culture. The levels of melatonin (MEL) and corticosterone (CORT) hormones were investigated simultaneously, by the LuminexTM immunoassay system in mice plasma, after Citrus aurantium and Citrus sinensis EOs inhalation for 30 min. The plasma was analyzed by headspace through gas chromatography coupled to mass spectrometry for investigation of the EO components. Mice were submitted to behavioral testing to research anxiolytic like, sedative, and antidepressant-like effects. The inhalation of atmosphere obtained from vaporization of 10% solution of this Citrus EO separately did not affect MEL or CORT plasma levels; that is, the MEL and CORT levels did not present variation in function of the EO in the schedule used. On the other hand, the imipramine positive control used altered the level of MEL as expected. The EO constituents were detected in plasma at different ratios that is present in inhaled EO. Behavioral tests showed that the inhalation of 10% C. sinensis EO presents an anxiolytic-like and sedative effect. Thus, C. sinensis EO can be a valuable tool for treatment of the anxiety disturbs, apparently without interference with MEL and CORT physiological levels. PMID- 29168241 TI - Can a child and family health service improve early childhood health outcomes in an urban Aboriginal community? AB - AIMS: To describe the engagement of a cohort of urban Aboriginal families with an Early Childhood Health Service, and to assess any association of engagement with the service with screening by the Edinburgh Post-Natal Depression Scale (EPDS), full breastfeeding rates and post-natal smoking status. METHODS: Routine electronic medical record data collected by a Child and Family Health Nurse between 2011 and 2014 was analysed retrospectively. Associations between use of the service and acceptance of EPDS, breastfeeding rates and post-natal smoking status were determined using binary and multinomial multiple logistic regression analyses. RESULTS: There were 424 Aboriginal babies and 215 mothers included in the study. Each occasion of service increased the odds of accepting screening with the EPDS (odds ratio (OR) 1.02, 95% confidence interval (CI) 1.00-1.03, P = 0.04) and complete breastfeeding (OR 1.11, CI 1.01-1.23, P = 0.04), but not of quitting smoking (OR 0.99, CI 0.96-1.02, P = 0.34). Despite accounting for engagement with the service, overall uptake of the EPDS remained low; of 267 offers for EPDS screening, only 115 were accepted (43%). CONCLUSION: The service was accessed in increasing numbers during the study period. Mothers who utilised the service more frequently were more likely to accept EPDS screening and exclusively breastfeed; however, acceptance of EPDS screening remained low overall. Further research is recommended to investigate the low acceptance of EPDS in this Aboriginal population and whether those results are transferable to other communities. PMID- 29168242 TI - Compositional differences between Copaxone and Glatopa are reflected in altered immunomodulation ex vivo in a mouse model. AB - Copaxone (glatiramer acetate, GA), a structurally and compositionally complex polypeptide nonbiological drug, is an effective treatment for multiple sclerosis, with a well-established favorable safety profile. The short antigenic polypeptide sequences comprising therapeutically active epitopes in GA cannot be deciphered with state-of-the-art methods; and GA has no measurable pharmacokinetic profile and no validated pharmacodynamic markers. The study reported herein describes the use of orthogonal standard and high-resolution physicochemical and biological tests to characterize GA and a U.S. Food and Drug Administration-approved generic version of GA, Glatopa (USA-FoGA). While similarities were observed with low resolution or destructive tests, differences between GA and USA-FoGA were measured with high-resolution methods applied to an intact mixture, including variations in surface charge and a unique, high-molecular-weight, hydrophobic polypeptide population observed only in some USA-FoGA lots. Consistent with published reports that modifications in physicochemical attributes alter immune related processes, genome-wide expression profiles of ex vivo activated splenocytes from mice immunized with either GA or USA-FoGA showed that 7-11% of modulated genes were differentially expressed and enriched for immune-related pathways. Thus, differences between USA-FoGA and GA may include variations in antigenic epitopes that differentially activate immune responses. We propose that the assays reported herein should be considered during the regulatory assessment process for nonbiological complex drugs such as GA. PMID- 29168243 TI - Iron sucrose: assessing the similarity between the originator drug and its intended copies. AB - Iron sucrose (IS) is a complex nanocolloidal intravenous suspension used in the treatment of iron-deficiency anemia. Follow-on IS products (iron sucrose similars (ISSs)) have obtained marketing authorization by the generic pathway, implying that identical copies of IS may be manufactured. However, recent prospective and retrospective clinical studies showed discrepancies in clinical outcomes, which might be related to differences in physicochemical properties. The aim of this work is to measure and compare the physicochemical properties of IS and three ISSs available in the market using innovative analytical procedures. The comprehensive elucidation of size, size distribution, morphology, and stability of these complex drugs revealed very significant differences between the products. This study serves to provide the basis to define critical quality attributes that may be linked to differences in clinical outcome and thus may contribute to an adequate regulatory approach for IS and its follow-on products. PMID- 29168244 TI - Using preceding hospital admissions to identify children at risk of developing acute rheumatic fever. AB - AIMS: New Zealand (NZ) Maori and Pacific children have high rates of acute rheumatic fever (ARF). Around 150 new cases arise each year. As part of the national ARF prevention programme, funding is available to improve housing. To obtain maximum benefit from interventions, an effective tool is needed for targeting high-risk children. This study aimed to assess the effectiveness of using hospitalisations for identifying children at risk of subsequent ARF. METHODS: Three potentially avoidable hospitalisation (PAH) groups were investigated, including diseases thought to be influenced by housing. All were developed using expert opinion or systematic reviews. These were: (i) the PAH conditions associated with the housing environment (PAHHE) group; (ii) the Crowding group; and (iii) the Ministry of Health (MoH) group. We analysed NZ public hospital discharge data (2000-2014). The prevalence of ARF among patients hospitalised in each group was calculated to estimate sensitivity and potential effectiveness. The number needed to screen (NNS) to identify one ARF case was estimated as a measure of efficiency. RESULTS: Nearly one-third of ARF patients experienced a PAH as children (before developing ARF). Sensitivity for detecting future ARF ranged from <5% (MoH group) to 27% (PAHHE group). NNS ranged from 502.4 (PAHHE) to 707.5 (MoH). CONCLUSIONS: Because ARF is relatively rare, observing hospitalisations is not particularly efficient for targeting prevention activities for this condition alone. However, housing interventions are likely to improve multiple outcomes; thus, the hospital setting is still useful for identifying at-risk children who could benefit from such programmes. PMID- 29168245 TI - Homology-based hydrogen bond information improves crystallographic structures in the PDB. AB - The Protein Data Bank (PDB) is the global archive for structural information on macromolecules, and a popular resource for researchers, teachers, and students, amassing more than one million unique users each year. Crystallographic structure models in the PDB (more than 100,000 entries) are optimized against the crystal diffraction data and geometrical restraints. This process of crystallographic refinement typically ignored hydrogen bond (H-bond) distances as a source of information. However, H-bond restraints can improve structures at low resolution where diffraction data are limited. To improve low-resolution structure refinement, we present methods for deriving H-bond information either globally from well-refined high-resolution structures from the PDB-REDO databank, or specifically from on-the-fly constructed sets of homologous high-resolution structures. Refinement incorporating HOmology DErived Restraints (HODER), improves geometrical quality and the fit to the diffraction data for many low resolution structures. To make these improvements readily available to the general public, we applied our new algorithms to all crystallographic structures in the PDB: using massively parallel computing, we constructed a new instance of the PDB-REDO databank (https://pdb-redo.eu). This resource is useful for researchers to gain insight on individual structures, on specific protein families (as we demonstrate with examples), and on general features of protein structure using data mining approaches on a uniformly treated dataset.

PMID- 29168246 TI - Immunostimulatory effects of cordycepin-enriched WIB-801CE from Cordyceps militaris in splenocytes and cyclophosphamide-induced immunosuppressed mice. AB - The medicinal mushroom Cordyceps militaris has been reported to possess anticancer and immunomodulatory effects. We investigated the immunostimulatory effects of culture supernatant of C. militaris (WIB-801CE) by examining its in vitro enhancing effects on cell proliferation and cytokine releases in splenocytes and its in vivo effects on cyclophosphamide-induced immunosuppressed mice. WIB-801CE enhanced normal and methotrexate-induced cell proliferation. WIB 801CE significantly ameliorated interleukin (IL)-2, interferon-gamma, and tumor necrosis factor-alpha secretion in methotrexate-induced splenocytes. Oral administration of WIB-801CE effectively increased the cyclophosphamide-suppressed splenocyte proliferation and natural killer cytotoxic activity. WIB-801CE effectively recovered cyclophosphamide-induced decreases in IL-2, interferon gamma, tumor necrosis factor-alpha, and IL-10 level. The collective data implicate WIB-801CE as a therapeutic candidate in ameliorating the immunosuppression through immunostimulatory properties. PMID- 29168248 TI - Evaluation of C-reactive protein as an inflammatory marker of pemphigus foliaceus and superficial pyoderma in dogs. AB - BACKGROUND: C-reactive protein (CRP) is a major acute phase protein in dogs and may be an inflammatory marker of autoimmune diseases. HYPOTHESIS/OBJECTIVES: To measure pre- and post-treatment CRP levels in dogs with superficial pyoderma (SP) and pemphigus foliaceus (PF) compared to normal dogs; to evaluate possible correlation between CRP values, indirect immunofluorescence (IIF), and pemphigus foliaceus extent and severity index (PEFESI) scores. ANIMALS: Fifty nine dogs divided into three groups: Group I (control, n = 31), Group II (SP, n = 14) and Group III (PF, n = 14). METHODS: CRP levels were measured in Group I dogs. Skin biopsies of Groups II and III dogs were obtained for histopathological examination. In Group II dogs, CRP levels were measured at days 0, 15, 30 and 60. In Group III dogs were evaluated by PEFESI, IIF and CRP levels at days 0, 15, 30, 60 and 90. RESULTS: Group III showed a higher median CRP (37.4 mg/mL) compared to the other groups (Group I, CRP 2.9 mg/mL, P < 0.0001; Group II CRP 3.8 mg/mL, P = 0.008). There was no significant difference in CRP levels between groups I and II. IIF titres and CRP levels decreased in most cases of PF with clinical improvement. Dogs with CRP >10.6 MUg/mL were 5.5 times more likely to have PF than SP. There was a strong positive correlation between CRP values and PEFESI and a weak positive correlation between CRP values and IIF titres. CONCLUSION AND CLINICAL IMPORTANCE: CRP levels are increased in dogs with PF and exceed levels found in most dogs with SP. PMID- 29168249 TI - Violent crime redistribution in a city following a substantial increase in the number of off-sale alcohol outlets: A Bayesian analysis. AB - INTRODUCTION AND AIMS: This study examined whether the introduction of a large number of off-premise alcohol outlets into a city over a brief period of time could affect rates of violent crime. DESIGN AND METHODS: The study analysed annual counts of violent crime across 172 US Census block groups in Lubbock, Texas from 2006 through 2011. Spatial Poisson models related annual violent crime counts within each block group to off-premise and on-premise alcohol outlets active during this time period as well as neighbourhood socio-demographic characteristics. The effects of alcohol outlets were assessed both within block groups and across adjacent block groups. RESULTS: On-premise outlets had a small, significant positive association with violence within a given block group. A similar well-supported local effect for off-premise outlets was not found. However, the spatially lagged effect for off-sale premises was well-supported, indicating that greater densities of these outlets were related to greater rates of violent crime in adjacent areas. DISCUSSION AND CONCLUSIONS: While these analyses confirmed a previous time-series analysis in finding no city-wide effect of the increase in off-premise outlets, they do suggest that such outlets in a local area may be related to violence in nearby geographic areas. They indicate the importance of examining neighbourhood-specific effects of alcohol outlets on violence in addition to the city-wide effects. They also present further evidence supporting the need to examine the differential effects of on-sale and off-sale premises. PMID- 29168250 TI - The effect of skin-to-skin care on cerebral oxygenation during nasogastric feeding of preterm infants. AB - AIM: To describe cerebral oxygenation during gavage feeding of preterm infants during incubator and skin-to-skin care. METHODS: Further analysis of data from two crossover studies comparing cerebral oxygenation, heart rate and oxygen saturation during skin-to-skin care with incubator care. Data were analysed in three epochs; 10 minutes prefeed, during-feed and 10 minutes postfeed. Measurements from infants fed during incubator care were compared with those obtained during skin-to-skin care. RESULTS: In 39 infants [median (IQR) 27.8 (26.1-30.0) weeks' gestation], there was no difference in cerebral oxygenation between pre-, during- and postfeed. Heart rate increased by three beats per minute postfeed compared with during-feed. Twenty infants received two gavage feeds, one feed in the incubator and another during skin-to-skin care. There was no difference in cerebral oxygenation and heart rate; peripheral oxygen saturation decreased by 3% during feeding whilst skin-to-skin care compared with feeding in the incubator. CONCLUSION: Cerebral oxygenation remained stable before, during and after gavage feeding in an incubator and during skin-to-skin care. The small decrease in oxygen saturation whilst receiving gavage feeding during skin-to-skin care is unlikely to be clinically important, providing reassurance that preterm infants maintain physiological stability during skin-to skin care. PMID- 29168251 TI - Bendamustine plus rituximab for indolent B-cell lymphoma of renal significance. AB - Treatment of indolent B-cell non-Hodgkin lymphomas (iNHL) of renal significance is challenging given the need for deep and prolonged hematological response to restore and control renal function overtime, yet to be balanced with the risk of adverse drug-related events. This prospective single-center study included 20 patients with iNHL of renal significance (tubulointerstitial presentation [n = 8], glomerulopathy with or without monoclonal Ig deposits [n = 12]) who received a steroid-sparing regimen of rituximab plus bendamustine (BR), with either no or <1 month of steroid intake (as a first line therapy in 80%). Seventeen patients (85%) achieved a complete (CHR, n = 12) or a partial (PHR, n = 5) hematological response. Nine out of the 12 patients (75%) with iNHL-related glomerulopathy had a complete (CRR) or a partial (PRR) renal response. Among the six patients with glomerulopathy and CHR, five had a CRR (83%) compared to 1/6 (17%) that did not reach CHR. eGFR increased from 38 to 58 mL/min/1.73 m2 , and returned to baseline in five patients. Among the eight patients with a tubulointerstitial presentation, six (75%) had a renal response (5 CRR), and eGFR increased from 29 to 48 mL/min/1.73 m2 . One patient with a PHR had a renal relapse. Mortality rate was 10% at 12 months. The BR regimen was well tolerated overall. Thus, despite severe renal disease at presentation, a relapsing iNHL in 20% of patients and several comorbidities, the BR regimen was efficient and safe in our series. It should be further assessed as a first line therapy for patients with iNHL of renal significance. PMID- 29168254 TI - Ethanol Iris tenuifolia extract reduces brain damage in a mouse model of cerebral ischaemia. AB - In the previous experiments, the neuroprotective role of Iris tenuifolia Pall. (IT) in the model of middle cerebral artery occlusion (MCAO) was investigated. In addition, the concentrations of the cytokines tumour necrosis factor-alpha and interleukin-6 in blood plasma were measured. It was found that IT administered 1 hr prior to MCAO or immediately after MCAO reduced infarct volume significantly. IT application 1 and 4 hr after MCAO, respectively, was without any effect on infarct volume. There were no significant changes as regards tumour necrosis factor-alpha, whereas interleukin-6 concentrations were increased in blood plasma. This is the first evidence that flavonoids from Iris tenuifolia exert protective effects in the in vivo MCAO model. Our results suggest that these flavonoids are likely to be beneficial to humans by virtue of their ability to reduce infarct volume.

AB - BACKGROUND: Alloimmunization through blood transfusion, transplantation, or circulating fetal cells during pregnancy is a significant concern. Some exposed individuals make alloantibodies while others do not, implying variation in genetic risk factors. STUDY DESIGN AND METHODS: We conducted a genomewide association study (GWAS) of 9,427,497 single-nucleotide polymorphisms (SNPs) to identify genetic variants for HLA alloimmunization in previously pregnant blood donors with (n = 752) and without (n = 753) HLA Class I or II alloantibodies. RESULTS: A SNP in the neurexophilin 2 (NXPH2) gene surpassed genome-wide significance (p = 2.06 * 10-8 ), with multiple adjacent markers p < 10-6 , for women with anti-Class I alloantibodies only. Little is currently known about the function of NXPH2, although gene family members have been shown to impact immunity. SNPs in the E2F7 gene, a transcription factor related to cell cycle control and cellular proliferation, also approached genomewide significance (p = 2.5 * 10-7 ). CONCLUSION: Further work to extend the GWAS approach and to characterize variants in NXPH2 and E2F7 in the context of alloantibody formation is warranted. PMID- 29168252 TI - Global substrate specificity profiling of post-translational modifying enzymes. AB - Enzymes that modify the proteome, referred to as post-translational modifying (PTM) enzymes, are central regulators of cellular signaling. Determining the substrate specificity of PTM enzymes is a critical step in unraveling their biological functions both in normal physiological processes and in disease states. Advances in peptide chemistry over the last century have enabled the rapid generation of peptide libraries for querying substrate recognition by PTM enzymes. In this article, we highlight various peptide-based approaches for analysis of PTM enzyme substrate specificity. We focus on the application of these technologies to proteases and also discuss specific examples in which they have been used to uncover the substrate specificity of other types of PTM enzymes, such as kinases. In particular, we highlight our multiplex substrate profiling by mass spectrometry (MSP-MS) assay, which uses a rationally designed, physicochemically diverse library of tetradecapeptides. We show how this method has been applied to PTM enzymes to uncover biological function, and guide substrate and inhibitor design. We also briefly discuss how this technique can be combined with other methods to gain a systems-level understanding of PTM enzyme regulation and function. PMID- 29168256 TI - Alcohol taxes' contribution to prices in high and middle-income countries: Data from the International Alcohol Control Study. AB - INTRODUCTION: Taxation is increasingly being used as an effective means of influencing behaviour in relation to harmful products. In this paper we use data from six participating countries of the International Alcohol Control Study to examine and evaluate their comparative prices and tax regimes. METHODS: We calculate taxes and prices for three high-income and three middle-income countries. The data are drawn from the International Alcohol Control survey and from the Alcohol Environment Protocol. Tax systems are described and then the rates of tax on key products presented. Comparisons are made using the Purchasing Power Parity rates. The price and purchase data from each country's International Alcohol Control survey is then used to calculate the mean percentage of retail price paid in tax weighted by actual consumption. RESULTS: Both ad valorem and specific per unit of alcohol taxation systems are represented among the six countries. The prices differ widely between countries even though presented in terms of Purchasing Power Parity. The percentage of tax in the final price also varies widely but is much lower than the 75% set by the World Health Organization as a goal for tobacco tax. CONCLUSION: There is considerable variation in tax systems and prices across countries. There is scope to increase taxation and this analysis provides comparable data, including the percentage of tax in final price, from some middle and high-income countries for consideration in policy discussion. PMID- 29168257 TI - Effect of privatized managed care on public insurance spending and generosity: Evidence from Medicaid. AB - States choose to provide Medicaid coverage via managed care or traditional fee for-service. Managed care provided by private insurers poses higher contracting costs and information asymmetry than traditional fee-for-service but potentially improves efficiency and reduces spending. Evaluating the effect of managed care on Medicaid spending is challenging because adoption of managed care is nonrandom and may be driven by local economic shocks that simultaneously affect Medicaid spending. This study implements a dynamic panel framework to estimate the effect of managed care enrollment on spending levels and program design. Results show reductions in Medicaid spending larger than previously found in cross-state studies: A 10% increase of managed care enrollment reduces state Medicaid spending by 2.94%, or approximately $55 million. The study identifies which areas of spending are differentially affected by managed care enrollment and whether savings from managed care affect Medicaid design, specifically coverage generosity. PMID- 29168258 TI - Potential effect of recombinant thrombomodulin on ischemia-reperfusion liver injury in rats. AB - AIM: Liver ischemia-reperfusion (I/R) injury is a severe complication of liver surgery. However, the responsible molecular mechanism remains unclear. High mobility group box 1 (HMGB1) is released from the nuclei of cells and behaves as a damage-associated molecular pattern. The aim of this study is to reveal the roles of HMGB1 and the effects of recombinant thrombomodulin (rTM) in I/R liver injury. METHODS: Rats underwent partial hepatic ischemia followed by reperfusion, and changes in HMGB1 were assessed. Recombinant thrombomodulin was used as an inhibitor of HMGB1. RESULTS: In rats with I/R injury, the HMGB1 level significantly decreased in the liver tissue and significantly increased in the serum after surgery (P < 0.001 for both). No difference in the HMGB1 level in the hepatocytes was observed between the rTM(-) group and rTM(+) group after surgery. Conversely, the serum HMGB1 level was significantly lower in the rTM(+) group than the rTM(-) group after surgery (P < 0.001). The levels of tumor necrosis factor-alpha and interleukin-6 in the liver tissue 24 h after surgery were significantly lower in the rTM(+) group than the rTM(-) group (P < 0.001). The plasma alanine aminotransferase level at 24 h after surgery of the rTM(+) group was significantly decreased after surgery compared with that of the rTM(-) group (P < 0.001). The necrotic area of the liver tissue 24 h after surgery was significantly smaller in the rTM(+) group than the rTM(-) group (P < 0.001). CONCLUSIONS: Recombinant thrombomodulin can serve as a treatment for I/R liver injury by inhibiting HMGB1. PMID- 29168259 TI - Constipation management in people with intellectual disability: A systematic review. AB - BACKGROUND: Constipation can lead to serious health issues and death. This systematic review summarizes international research pertaining to the management of constipation in people with intellectual disability. METHOD: Studies published from 1990 to 2017 were identified using Medline, Cinahl, PsycINFO, Web of Science, email requests and cross-citations. Studies were reviewed narratively in relation to identified themes. RESULTS: Eighteen studies were reviewed in relation to three themes: laxative receipt; interventions (dietary fibre, abdominal massage and macrogol); and staff issues (knowledge and training). Laxative polypharmacy was common. Studies report positive results for dietary fibre and abdominal massage although study quality was limited. CONCLUSION: The main management response to constipation in people with intellectual disability is laxative use despite limited effectiveness. An improved evidence base is required to support the suggestion that an individualized, integrated bowel management programme may reduce constipation and associated health conditions in people with intellectual disability. PMID- 29168260 TI - Prosystemin, a prohormone that modulates plant defense barriers, is an intrinsically disordered protein. AB - Prosystemin, originally isolated from Lycopersicon esculentum, is a tomato pro hormone of 200 aminoacid residues which releases a bioactive peptide of 18 aminoacids called Systemin. This signaling peptide is involved in the activation of defense genes in solanaceous plants in response to herbivore feeding damage. Using biochemical, biophysical and bioinformatics approaches we characterized Prosystemin, showing that it is an intrinsically disordered protein possessing a few secondary structure elements within the sequence. Plant treatment with recombinant Prosystemin promotes early and late plant defense genes, which limit the development and survival of Spodoptera littoralis larvae fed with treated plants. PMID- 29168261 TI - "Impact of drug-reimbursement policies on prescribing: A case-study of a newly marketed long-acting injectable antipsychotic among relapsed schizophrenia patients". AB - OBJECTIVE: To quantify and explain variation in use of long-acting injectable antipsychotics (LAIs) in the United States, and understand the relationship between patient characteristics, drug reimbursement policies, and LAI prescribing after relapse. METHODS: A cohort of recently relapsed patients with schizophrenia ages 18 to 64, were identified immediately after discharge from a related inpatient hospitalization, partial hospitalization, or emergency room visit, drawn from 2004 to 2006 Medicaid claims, and followed for 90 days until LAI initiation. Data on state-level Medicaid prior authorization (PA) policies for LAIs were collected. Sequential longitudinal Poisson regression models were developed to understand the relationship between patient and PA policy variables and LAI prescribing, including prior adherence to oral antipsychotics, demographics, clinical variables, and presence of PA policy for LAI. RESULTS: Among 36 282 patients, 3.1% received risperidone LAI, and 3.8% received a first generation (FGA) LAI with wide variation across states. Prior adherence ranged from 29% to 89% but was marginally associated with initiation and did not explain variation for LAI prescribing. FGA initiation was associated with geography and race/ethnicity but not PA policy. For risperidone LAI initiation, demographics and clinical factors explained, respectively, 5.0% and 3.0% of the variation; PA policy had a large negative association with initiation (RR = 0.41; 95%CI 0.20 0.87) and explained 8.4% of the variation. CONCLUSIONS: PA policies may represent a major treatment barrier for risperidone LAI among relapsed patients. Non adherence plays a little role in predicting which patients receive LAIs. Policy makers and health insurers will need to consider these findings when guiding the use of LAIs. KEY POINTS Among a nationwide cohort of relapsed schizophrenia patients enrolled in US Medicaid, 3.1% received Risperdal Consta, a long-acting injectable antipsychotic (LAI), and 3.8% initiated a first-generation first generation LAI within 90 days after discharge. During 2004 to 2006, there was marked variation in 90 day post-relapse initiation of Risperdal-Consta-a newly marketed medication during this period-and also marked variation in 90 day post relapse initiation of any first-generation LAI, which appeared to be associated with race/ethnicity and geography. Prior authorization policies were associated with substantially lower initiation of Risperdal Consta in this cohort of relapsed patients even after accounting for clinical indication (non-adherence), relapse history, demographics, adjunctive medication, and mental health service use. PMID- 29168262 TI - Cross-border migration and initiation of others into drug injecting in Tijuana, Mexico. AB - INTRODUCTION AND AIMS: Efforts to prevent injection drug use (IDU) are increasingly focusing on the role that people who inject drugs (PWID) play in facilitating the entry of others into this behaviour. This is particularly relevant in settings experiencing high levels of IDU, such as Mexico's northern border region, where cross-border migration, particularly through forced deportation, has been found to increase a range of health and social harms related to injecting. DESIGN AND METHODS: PWID enrolled in a prospective cohort study in Tijuana, Mexico, since 2011 were interviewed semi-annually, which solicited responses on their experiences initiating others into injecting. Univariate and multivariable logistic regression analyses were conducted at the Preventing Injection by Modifying Existing Responses (PRIMER) baseline, with the dependent variable defined as reporting ever initiating others into injection. The primary independent variable was lifetime deportation from the USA to Mexico. RESULTS: Among 532 participants, 14% (n = 76) reported initiating others into injecting, the majority of participants reporting initiating acquaintances (74%, n = 56). In multivariable analyses, initiating others into injecting was independently associated with reporting living in the USA for 1-5 years [adjusted odds ratio (AOR) = 2.42; 95% confidence interval (CI) 1.22-4.79, P = 0.01], and methamphetamine and heroin injection combined (AOR = 3.67; 95% CI 1.11-12.17, P = 0.03). Deportation was not independently associated with initiating others into injecting. DISCUSSION AND CONCLUSIONS: The impact of migration needs to be considered within binational programming seeking to prevent the expansion of epidemics of injecting and HIV transmission among mobile populations residing in the Mexico-USA border region.

AB - Miracle fruit (Synsepalum dulcificum) seed oil (MFSO) contains phytochemicals and nutrients reported to affect musculoskeletal performance. The purpose of this study was to assess the safety and efficacy of a compression wristband containing MFSO on its ability to measurably improve the hand and finger motor skills of participants. Healthy right-handed participants (n = 38) were randomized in this double-blind, placebo-controlled study of MFSO and vehicle wristbands. Subjects wore the wristband on their left hand 4-6 weeks and then only on their right hand 2-4 weeks; the contralateral untreated hand served as an additional control. Twelve hand/finger motor skills were measured using quantitative bio instrumentation tests, and subject self-assessment questionnaires were conducted. With each hand, in 9/12 tests, the MFSO group showed a clinically meaningful average improvement compared with an average worsening in the vehicle group. Statistical superiority to the control treatment group was exhibited in 9/12 tests for each hand (p < .01). After discontinuing the MFSO wristband on the left hand, test values regressed toward baseline levels. Subjects favored the MFSO wristband over the control, rating it as effective in improving their motor skills. Use of the MFSO wristband may improve an individual's manual dexterity skills and ability to maintain this performance.

AB - INTRODUCTION AND AIMS: Limited attention has been given to the predictors of mental health diagnoses among people who inject drugs (PWID) in community settings. Therefore, we sought to longitudinally examine the prevalence, incidence and predictors of mental disorder diagnosis among a community-recruited cohort of PWID. DESIGN AND METHODS: Data were derived from two prospective cohort studies of PWID (VIDUS and ACCESS) in Vancouver, Canada between December 2005 and May 2015. We used multivariable extended Cox regression to identify factors independently associated with self-reported mental disorder diagnosis during follow-up among those without a history of such diagnoses at baseline. RESULTS: Among the 923 participants who did not report a mental disorder at baseline, 206 (22.3%) reported a first diagnosis of a mental disorder during follow-up for an incidence density of 4.29 [95% confidence interval (CI) 3.72-4.91] per 100 person years. In the multivariable analysis, female sex [adjusted hazards ratio (AHR) = 1.74, 95% CI 1.29-2.33], experiencing non-fatal overdose (AHR = 2.33, 95% CI 1.38 3.94), accessing any drug or alcohol treatment (AHR = 1.68, 95% CI 1.24-2.27), accessing any community health or social services (AHR = 1.53, 95% CI 1.02-2.28) and experiencing violence (AHR = 1.60, 95% CI 1.12-2.29) were independently associated with a mental disorder diagnosis at follow-up. DISCUSSION AND CONCLUSIONS: We observed a high prevalence and incidence of mental disorders among our community-recruited sample of PWID. The validity and implication of these diagnoses for key substance use and public health outcomes are an urgent priority. PMID- 29168265 TI - Two-stage identification of SNP effects on dynamic poplar growth. AB - This project proposes an approach to identify significant single nucleotide polymorphism (SNP) effects, both additive and dominant, on the dynamic growth of poplar in diameter and height. The annual changes in yearly phenotypes based on regular observation periods are considered to represent multiple responses. In total 156,362 candidate SNPs are studied, and the phenotypes of 64 poplar trees are recorded. To address this ultrahigh dimensionality issue, this paper adopts a two-stage approach. First, the conventional genome-wide association studies (GWAS) and the distance correlation sure independence screening (DC-SIS) methods (Li et al., 2012) were combined to reduce the model dimensions at the sample size; second, a grouped penalized regression was applied to further refine the model and choose the final sparse SNPs. The multiple response issue was also carefully addressed. The SNP effects on the dynamic diameter and height growth patterns of poplar were systematically analyzed. In addition, a series of intensive simulation studies was performed to validate the proposed approach. PMID- 29168266 TI - Profile analysis of treatment effect changes in eating disorder indicators. AB - We investigated differential treatment effects on specific eating disorder (ED) indicators to enhance conclusions about treatment efficacy. Profile Analysis via Multidimensional Scaling, which identifies core profiles in a population and interprets person profiles with core profile information, was utilized to identify core profiles from a sample of 5,177 patients who were repeatedly measured with the ED inventory-2 at admission and at discharge. To assess differential treatment effects for individual ED indicators, we compared the core profiles at admission with those at discharge. Three core profiles were identified and labeled as High Body Dissatisfaction with Low Bulimia (Core Profile 1), High Interoceptive Awareness with Low Body Dissatisfaction (Core Profile 2), and High Ineffectiveness with Low Bulimia (Core Profile 3). Treatment had the greatest effects on Core Profile 2. The patients whose profile patterns were similar to that of Core Profiles 1 and 2 were positively related with weight gain. However, treatment was least on Core Profile 3, and the patients whose profile patterns were like that of Core Profile 3 were negatively related with weight gain. In conclusion, those patients who fit Core Profile 3 may benefit from different treatment modalities than those that are standard in inpatient settings. PMID- 29168267 TI - Explicit and implicit attitudes towards people with intellectual disabilities: The role of contact and participant demographics. AB - BACKGROUND: Intellectual disability research has concentrated on self-reported explicit attitudes with little focus on implicit attitudes. Such attitudes are evaluations which occur with or without conscious awareness, respectively. This investigation examined participants' (N = 234) attitudes towards individuals with intellectual disabilities with reference to participants' gender, age, level of education, frequency of contact and closeness. METHOD: UK adults completed explicit (ATTID) and implicit attitude (ST-IAT) measures, and provided demographics via an online survey. RESULTS: Participant demographics predicted explicit attitudes-with differing cognitive, affective and behavioural associations. Contact frequency was most significant. Implicit attitudes were not predicted, evidencing implicit-explicit attitude differences. CONCLUSIONS: The results encourage more implicit-explicit attitude relationship research regarding disability. The associations between demographics, contact and implicit attitudes should be explored further. Research should question whether implicit attitudes reflect participants' true beliefs-denoting less importance to demographics-or whether they reflect wider societal values rather than individuals' attitudes. PMID- 29168268 TI - Lifetime marijuana use and subclinical atherosclerosis: the Coronary Artery Risk Development in Young Adults (CARDIA) study. AB - BACKGROUND AND AIMS: Unlike tobacco, the effect of marijuana smoke on subclinical atherosclerosis, a surrogate measure for cardiovascular disease, is not known. This study aimed to determine the association between lifetime exposure to marijuana and measures of subclinical atherosclerosis in mid-life. DESIGN, SETTING AND PARTICIPANTS: We used data from the US-based Coronary Artery Risk Development in Young Adults (CARDIA) study, a cohort of black and white men and women aged 18-30 years at baseline in 1985-86, with up to seven follow-up examinations over 25 years. A total of 3498 participants in the CARDIA study were included in this study. MEASUREMENTS: Cumulative years of exposure to marijuana (expressed in 'marijuana-years', with 1 marijuana-year equivalent to 365 days of use) using repeated assessments every 2-5 years for 25 years. Abdominal artery calcium (AAC) and coronary artery calcium (CAC) scores were measured by computed tomography at year 25 examination. RESULTS: Among 3117 participants with AAC and CAC measurements, 2627 (84%) reported past marijuana use and 1536 (49%) past daily tobacco smoking. Compared with tobacco smokers, 46% of whom reported 10 or more pack-years of use, only 12% of marijuana users reported 5 or more marijuana years of use and only 6% reported having used marijuana daily. We found a significant interaction between never and ever tobacco users on the association between cumulative marijuana use and AAC (P = 0.05). Among those who never smoked tobacco, cumulative marijuana-years were not associated with AAC or CAC in models adjusted for demographics, cardiovascular risk factors, licit and illicit drug exposure and depression symptoms. However, among ever tobacco smokers, marijuana exposure was associated with AAC and CAC. At 5 marijuana-years of exposure, using AAC = 0 and CAC = 0 as a reference group, the odds ratio (OR) was 1.97 [95% confidence interval (CI) = 1.21-3.21, P = 0.007] for AAC > 0/CAC = 0 and 1.83 (95% CI = 1.02-3.31, P = 0.04) for CAC > 0), regardless of AAC. Tobacco smoking was associated strongly with both AAC and CAC. CONCLUSION: Marijuana use appears to be associated with subclinical atherosclerosis, but only among ever tobacco users. PMID- 29168269 TI - Adolescent ethanol intake alters cannabinoid type-1 receptor localization in astrocytes of the adult mouse hippocampus. AB - Cannabinoid type-1 (CB1 ) receptors are widely distributed in the brain and play important roles in astrocyte function and the modulation of neuronal synaptic transmission and plasticity. However, it is currently unknown how CB1 receptor expression in astrocytes is affected by long-term exposure to stressors. Here we examined CB1 receptors in astrocytes of ethanol (EtOH)-exposed adolescent mice to determine its effect on CB1 receptor localization and density in adult brain. 4-8 week-old male mice were exposed to 20 percent EtOH over a period of 4 weeks, and receptor localization was examined after 4 weeks in the hippocampal CA1 stratum radiatum by pre-embedding immunoelectron microscopy. Our results revealed a significant reduction in CB1 receptor immunoparticles in astrocytic processes of EtOH-exposed mice when compared with controls (positive astrocyte elements: 21.50 +/- 2.80 percent versus 37.22 +/- 3.12 percent, respectively), as well as a reduction in particle density (0.24 +/- 0.02 versus 0.35 +/- 0.02 particles/MUm). The majority of CB1 receptor metal particles were in the range of 400-1200 nm from synaptic terminals in both control and EtOH. Altogether, the decrease in the CB1 receptor expression in hippocampal astrocytes of adult mice exposed to EtOH during adolescence reveals a long lasting effect of EtOH on astrocytic CB1 receptors. This deficiency may also have negative consequences for synaptic function. PMID- 29168270 TI - A comparative evaluation of a new fully automated assay for von Willebrand factor collagen binding activity to an established method. AB - INTRODUCTION: Laboratory diagnosis of von Willebrand disease (VWD) is made by the measurement of von Willebrand factor (VWF) protein level and its activities. Current VWF activity tests include ristocetin cofactor and collagen binding (VWF:CB) assays. AIM: We have undertaken an evaluation of a new fully automated VWF:CB assay relative to an established enzyme-linked immunosorbent assay (ELISA) method. METHODS: The two analytical systems operate with different detection principles: a chemiluminescent method performed on ACL AcuStar Analyzer (the former) and a colorimetric ELISA by Asserachrom Stago (the latter) (type III collagen from human placenta). The HemosIL AcuStar VWF:CB assay is a chemiluminescent 2-step immunoassay that uses magnetic particles coated with a type III collagen triple-helical peptide. VWF:CB levels were determined in 50 healthy subjects and 100 VWD patients (22 type 1, 73 type 2 and 5 type 3). RESULTS: Eleven VWD samples reported VWF:CB values below the lower detection limit of one or both methods. The new method showed a good correlation with the ELISA method (r > .9, mean bias 3.85 IU/dL) in both healthy and VWD samples. One of 150 samples gave inconsistent results using the two assays, leading to an uncertain diagnosis of VWD type 1 (ELISA method) or type 2 MCB (fully automated method). CONCLUSION: The new assay is rapid and simple to use, with its ready-to use reagent cartridges. This VWF:CB assay, in addition to the measurement of VWF:Ag and VWF:RCo made on the same platform, gives additional information for the diagnosis of VWD in both nonspecialized and reference laboratories. PMID- 29168271 TI - N-Methyl-d-aspartate receptor co-agonist availability affects behavioral and neurochemical responses to cocaine: insights into comorbid schizophrenia and substance abuse. AB - Both schizophrenia (SZ) and substance abuse (SA) exhibit significant heritability. Moreover, N-methyl-d-aspartate receptors (NMDARs) have been implicated in the pathophysiology of both SZ and SA. We hypothesize that the high prevalence of comorbid SA in SZ is due to dysfunction of NMDARs caused by shared risk genes. We used transgenic mice with a null mutation of the gene encoding serine racemase (SR), the enzyme that synthesizes the NMDAR co-agonist d-serine and an established risk gene for SZ, to recreate the pathology of SZ. We determined the effect of NMDAR hypofunction resulting from the absence of d serine on motivated behavior by using intracranial self-stimulation and neurotransmitter release in the nucleus accumbens by using in vivo microdialysis. Compared with wild-type mice, SR-/- mice exhibited similar baseline intracranial self-stimulation thresholds but were less sensitive to the threshold-lowering (rewarding) and the performance-elevating (stimulant) effects of cocaine. While basal dopamine (DA) and glutamate release were elevated in the nucleus accumbens of SR-/- mice, cocaine-induced increases in DA and glutamate release were blunted. gamma-Amino-butyric acid efflux was unaffected in the SR-/- mice. Together, these findings suggest that the impaired NMDAR function and a consequent decrease in sensitivity to cocaine effects on behavior are mediated by blunted DA and glutamate responses normally triggered by the drug. Projected to humans, NMDAR hypofunction due to mutations in SR or other genes impacting glutamatergic function in SZ may render abused substances less potent and effective, thus requiring higher doses to achieve a hedonic response, resulting in elevated drug exposure and increased dependence/addiction.

PMID- 29168273 TI - Synergistic inhibition of cell proliferation by combined targeting with kinase inhibitors and dietary xanthone is a promising strategy for melanoma treatment. AB - alpha-Mangostin is a dietary xanthone that displays various biological activities, and numerous reports have shown its efficacy in cancer prevention and inhibition. As most agents have been shown to be ineffective as single-agent therapy for malignant melanoma (MM), the principle of targeted chemotherapy for MM is to use effective inhibitors and combination methods. In this study, we tested the cytotoxicity of several kinase inhibitors, including the glycogen synthase kinase (GSK)-3 inhibitor CHIR99021, and rapamycin, in combination with a dietary xanthone, alpha-mangostin, by screening from a kinase inhibitor library for melanogenesis in SK-MEL-2 MM cells, and verified these by clone formation efficiency, terminal dUTP nick end labelling, and expression of apoptosis-related proteins. We also explored the molecular mechanisms for the apoptosis-inducing effects reported. We found a marked synergistic effect of CHIR99021 or rapamycin in combination with alpha-mangostin, which we verified through apoptosis-related methods. These data provide a strong rationale for the use of alpha-mangostin as an adjunct to GSK-3 inhibitor or mammalian target of rapamycin inhibitor treatment. The intrinsic mechanism behind alpha-mangostin might be inhibition of phosphatidylinositol 3-kinase/AKT signalling and autophagy, and induction of reactive oxygen species generation. PMID- 29168274 TI - Antimicrobial properties of calcium hydroxide dressing when used for long-term application: A systematic review. AB - This review aims to evaluate the antimicrobial efficacy of calcium hydroxide against endodontic pathogens when used for 7 days or longer. A systematic electronic literature search was performed in the PubMed, Embase and EBSCO Dentistry & Oral Sciences Source databases using appropriate key words to identify investigations written in the English language that examined the association between the contact time of intracanal calcium hydroxide dressing and its antimicrobial properties. There were no exclusions based on study design. The search yielded 6993 publications. After duplicate removal, 5913 publications were identified and 11 studies met the inclusion criteria. Results showed that the antimicrobial effect of calcium hydroxide for contact times ranging between seven and 45 days is comparable. Two studies demonstrated contradictory findings when exposure was extended to more than 45 days. Future studies are warranted to investigate and optimise calcium hydroxide application for longer periods and identify the potential benefits of its use in clinical settings. PMID- 29168276 TI - Established and novel measures of upper limb impairment in children with Charcot Marie-tooth disease type 1A and riboflavin transporter deficiency type 2. AB - Hand function is a problem in patients with Charcot-Marie-Tooth disease type 1A (CMT1A) and Riboflavin Transporter Deficiency type 2 (RTD2). However, a detailed understanding of upper limb involvement in these conditions is lacking. The aim of this pilot study was to compare hand and upper limb function between children with CMT1A, RTD2 and healthy controls using established and novel outcome measures. Three age-and sex-matched groups of four children (5-15 years, 1 male/group) with CMT1A, RTD2, and healthy controls were assessed for function, strength, and sensation. Fatigue and muscle activity of the FDI was also assessed using a submaximal contraction at 40% of the participants' maximal voluntary contraction. Functional measures were most affected in children with RTD2 followed by children with CMT1A, compared to healthy controls. Strength was similarly impaired in CMT1A and RTD2 compared to controls (p < 0.05). Sensation was significantly impaired in RTD2 compared to CMT1A and controls (p = 0.008). While time to fatigue did not differ between groups, a decline in muscle activity while force remained constant showed that controls compensated with other muscles during the fatigue task while children with CMT1A and RTD2 did not have this compensatory ability. Children with CMT1A and RTD2 exhibited marked hand/upper limb impairment. These results suggest the upper limb should be a focus of rehabilitative therapy in affected children using sensitive outcome measures of strength and sensation, as well as functional activities of daily living, which are most relevant to the patient. PMID- 29168275 TI - 6-shogaol induces apoptosis and enhances radiosensitivity in head and neck squamous cell carcinoma cell lines. AB - Ginger (Zingiber officinale Roscoe) is used for a wide array of conditions in traditional medicine in Asia, but little is known about the effect on head and neck cancer. In this study, the effect of two major pharmacologically active compounds of ginger, 6-gingerol and 6-shogaol, were studied on head and neck cancer cell lines. Furthermore, experiments in combination with established treatment methods for head and neck cancer were performed. Proliferation assays showed a dose-dependent reduction of cell viability. Flow cytometry analysis revealed the induction of apoptosis. Western blot analysis indicated that the antiapoptotic protein survivin was suppressed after treatment. Although a combination of 6-shogaol with cisplatin exhibited no synergistic effect, the combination with irradiation showed a synergistic reduction of clonogenic survival. In conclusion, ginger compounds have many noteworthy effects on head and neck cancer cell lines. In particular, the enhancement of radiosensitivity is remarkable. PMID- 29168277 TI - Congenital limb deficiencies and major associated anomalies in Alberta for the years 1980-2012. AB - There is a wide range of the proportion of congenital anomalies associated with limb deficiencies reported in the literature. This variation is primarily attributed to methodology and classification differences. The distribution of associated anomalies among cases with congenital limb deficiencies in Alberta born between January 1, 1980 and December 31, 2012 is described. Of the 170 cases identified, most were live born (75.3%), male (61.8%), had longitudinal limb deficiencies (78.8%), and had associated anomalies outside the musculoskeletal system (77.6%). Significant associations between the preaxial longitudinal group and the central nervous, gastrointestinal, and cardiovascular systems are reported as well as between the postaxial longitudinal group and congenital hip and foot anomalies. Probable and possible syndrome diagnoses are described for cases with recognized malformation patterns.

AB - Conjugated polymers (CPs) are emerging and appealing light harvesters for photocatalytic water splitting owing to their adjustable band gap and facile processing. Herein, we report an advanced mild synthesis of three conjugated triazine-based polymers (CTPs) with different chain lengths by increasing the quantity of electron-donating benzyl units in the backbone. Varying the chain length of the CTPs modulates their electronic, optical, and redox properties, resulting in an enhanced performance for photocatalytic oxygen evolution, which is the more challenging half-reaction of water splitting owing to the sluggish reaction kinetics. Our results could stimulate interest in these functional polymers where a molecular engineering strategy enables the production of suitable semiconductor redox energetics for oxygenic photosynthesis. PMID- 29168280 TI - Quaternary beta2,2 -Amino Acids: Catalytic Asymmetric Synthesis and Incorporation into Peptides by Fmoc-Based Solid-Phase Peptide Synthesis. AB - beta-Amino acid incorporation has emerged as a promising approach to enhance the stability of parent peptides and to improve their biological activity. Owing to the lack of reliable access to beta2,2 -amino acids in a setting suitable for peptide synthesis, most contemporary research efforts focus on the use of beta3 - and certain beta2,3 -amino acids. Herein, we report the catalytic asymmetric synthesis of beta2,2 -amino acids and their incorporation into peptides by Fmoc based solid-phase peptide synthesis (Fmoc-SPPS). A quaternary carbon center was constructed by the palladium-catalyzed decarboxylative allylation of 4 substituted isoxazolidin-5-ones. The N-O bond in the products not only acts as a traceless protecting group for beta-amino acids but also undergoes amide formation with alpha-ketoacids derived from Fmoc-protected alpha-amino acids, thus providing expeditious access to alpha-beta2,2 -dipeptides ready for Fmoc SPPS. PMID- 29168281 TI - A review of urban impacts on avian life-history evolution: Does city living lead to slower pace of life? AB - The concept of a pace-of-life syndrome describes inter- and intraspecific variation in several life-history traits along a slow-to-fast pace-of-life continuum, with long lifespans, low reproductive and metabolic rates, and elevated somatic defences at the slow end of the continuum and the opposite traits at the fast end. Pace-of-life can vary in relation to local environmental conditions (e.g. latitude, altitude), and here we propose that this variation may also occur along an anthropogenically modified environmental gradient. Based on a body of literature supporting the idea that city birds have longer lifespans, we predict that urban birds have a slower pace-of-life compared to rural birds and thus invest more in self maintenance and less in annual reproduction. Our statistical meta-analysis of two key traits related to pace-of-life, survival and breeding investment (clutch size), indicated that urban birds generally have higher survival, but smaller clutch sizes. The latter finding (smaller clutches in urban habitats) seemed to be mainly a characteristic of smaller passerines. We also reviewed urbanization studies on other traits that can be associated with pace-of-life and are related to either reproductive investment or self maintenance. Though sample sizes were generally too small to conduct formal meta analyses, published literature suggests that urban birds tend to produce lower quality sexual signals and invest more in offspring care. The latter finding is in agreement with the adult survival hypothesis, proposing that higher adult survival prospects favour investment in fewer offspring per year. According to our hypothesis, differences in age structure should arise between urban and rural populations, providing a novel alternative explanation for physiological differences and earlier breeding. We encourage more research investigating how telomere dynamics, immune defences, antioxidants and oxidative damage in different tissues vary along the urbanization gradient, and suggest that applying pace-of-life framework to studies of variation in physiological traits along the urbanization gradient might be the next direction to improve our understanding of urbanization as an evolutionary process. PMID- 29168282 TI - Risk factors for asthma occurrence in children with early-onset atopic dermatitis: An 8-year follow-up study. AB - BACKGROUND: Children with early-onset atopic dermatitis (AD) are at substantial risk of developing asthma later in life, and identifying the critical window of detrimental exposure is advantageous for implementing preventive actions. The aim of this study was to evaluate the role of exposure to environmental modifiers during pregnancy and early childhood in asthma occurrence in an infantile AD cohort. METHODS: Eligible study participants were selected from the Taiwan Birth Cohort Study, which enrolled 24 200 newborns in 2005. We enrolled those cases who had been diagnosed as having AD before 3 years of age and followed them up till age 8. We excluded those ever diagnosed with asthma before AD onset. The dependent variable was defined in terms of whether the participant was diagnosed as having asthma before 8 years of age. We applied logistic regression models to evaluate the risks of exposure to different determinants in asthma occurrence. RESULTS: A total of 1549 children with AD had completed the 8-year follow-up, and 334 (21.6%) of them had asthma. The results revealed that male sex, lower birth order, maternal asthma history, maternal obesity before pregnancy, and environmental tobacco smoke exposure before 3 years of age were significant risk factors for further development of asthma. Furthermore, food allergy during early life, lower respiratory tract infection, and longer durations of symptomatic AD influenced asthma development later in life. CONCLUSIONS: The findings confirmed the critical determinants for asthma occurrence in infantile AD, which may enable a more personalized approach to the prevention of asthma. PMID- 29168283 TI - Emotion Regulation as a Transdiagnostic Feature Among Eating Disorders: Cross sectional and Longitudinal Approach. AB - Emotion regulation (ER) difficulties are observed in eating disorders (EDs). However, few studies have explored ER before and after treatment. The aims are as follows: to explore ER difficulties across ED types and a healthy control (HC) group (Study 1) and to assess pretreatment and post-treatment changes among ED types (Study 2). In Study 1, adult women with EDs (n = 438) and HC (n = 126) completed an assessment including Eating Disorders Inventory-2, Difficulties in Emotion Regulation Scale and Symptom Checklist-90-Revised. Patients in Study 2 (n = 69) were also reassessed after treatment. All ED types reported worse ER compared with HC (p < .001); also, ER differences were found between ED types. Prospective analyses show ER improvements after treatment (p < .001; |d| = 0.51), especially in patients with bulimia nervosa (p < .001; |d| = 1.03; Reliable Change Index = 9.79) with greater improvement in those with a better treatment outcome (p = .034). In conclusion, emotion dysregulation is a part of all forms of EDs. Furthermore, emotional dysregulation can be modified. ED treatments for anorexia nervosa and binge eating disorder might be enhanced by targeting ER skills. Copyright (c) 2017 John Wiley & Sons, Ltd and Eating Disorders Association. PMID- 29168284 TI - Association of Preoperative Serum Total Cholesterol Level with Postoperative Pain Outcomes after Laparoscopic Surgery for Gastric Cancer. AB - BACKGROUND: Opioid usage is reportedly increased in patients with advanced cancer and low total cholesterol (TC). The aim of this study was to determine the effects of preoperative serum TC levels on postoperative opioid usage in patients undergoing laparoscopic gastric cancer surgery. METHODS: We retrospectively analyzed the medical records of patients with gastric cancer who underwent laparoscopic gastrectomy at our institution between January 1, 2011 and July 31, 2017. We investigated the correlation between TC levels in the month before surgery and numeric rating scale (NRS) scores and opioid consumption on postoperative days (PODs) 0 to 3. The patients were stratified according to preoperative TC level (< 160 mg/dL, low; 160 to 199 mg/dL, medium; >= 200 mg/dL, high). RESULTS: TC and NRS scores (PODs 0, 1) for 1,919 eligible patients showed weak but significant positive coefficients (0.074 and 0.098 on POD 0 and POD 1, respectively, P < 0.01). After adjusting for confounders, there were no significant differences in postoperative NRS scores on PODs 0, 1, 2, or 3 or in oral morphine equivalents on PODs 0 to 3 according to TC level. CONCLUSION: Preoperative serum TC levels have no effect on pain outcomes in the 3 days following laparoscopic gastric surgery. PMID- 29168285 TI - Peutz -Jeghers syndrome (PJS). PMID- 29168287 TI - Multiplicity of skin cancers in Queensland and their cost burden to government and patients. AB - OBJECTIVE: To determine the cost burden to government and patients for individuals with multiple skin cancers. METHODS: We used self-reported baseline data on socio-demographics, phenotype and sun exposure behaviours from participants in the QSkin Sun and Health Study with at least one histopathologically confirmed keratinocyte cancer or melanoma (n=5,673). Linkage to Australian Medicare data (2011-2014) provided resource data and government and out-of-pocket patient costs. Generalised linear models examined costs by frequency of skin cancer groups separately for melanoma and keratinocyte cancer. RESULTS: Over three years, 539 participants were diagnosed with melanoma (11% had >=2 melanomas) and 5,134 participants were treated for keratinocyte cancers (10% had >=6). Median Medicare costs per person were $1,325 (maximum $6,117) for >=2 melanomas and $2,126 (maximum $54,618) for >=6 keratinocyte cancers. Increased costs were associated with private health insurance. CONCLUSIONS: Individuals who are multiply affected by skin cancers are relatively common and the accompanying individual and government cost burden can be substantial. These findings support skin cancer being classified as a chronic disease. Implications for public health: Over time, the economic burden for skin cancer for individuals and health providers is high and investment in prevention remains important from an economic viewpoint. PMID- 29168286 TI - Comparative proteomic profiling reveals a role for Cisd2 in skeletal muscle aging. AB - Skeletal muscle has emerged as one of the most important tissues involved in regulating systemic metabolism. The gastrocnemius is a powerful skeletal muscle composed of predominantly glycolytic fast-twitch fibers that are preferentially lost among old age. This decrease in gastrocnemius muscle mass is remarkable during aging; however, the underlying molecular mechanism is not fully understood. Strikingly, there is a ~70% decrease in Cisd2 protein, a key regulator of lifespan in mice and the disease gene for Wolfram syndrome 2 in humans, within the gastrocnemius after middle age among mice. A proteomics approach was used to investigate the gastrocnemius of naturally aged mice, and this was compared to the autonomous effect of Cisd2 on gastrocnemius aging using muscle-specific Cisd2 knockout (mKO) mice as a premature aging model. Intriguingly, dysregulation of calcium signaling and activation of UPR/ER stress stand out as the top two pathways. Additionally, the activity of Serca1 was significantly impaired and this impairment is mainly attributable to irreversibly oxidative modifications of Serca. Our results reveal that the overall characteristics of the gastrocnemius are very similar when naturally aged mice and the Cisd2 mKO mice are compared in terms of pathological alterations, ultrastructural abnormalities, and proteomics profiling. This suggests that Cisd2 mKO mouse is a unique model for understanding the aging mechanism of skeletal muscle. Furthermore, this work substantiates the hypothesis that Cisd2 is crucial to the gastrocnemius muscle and suggests that Cisd2 is a potential therapeutic target for muscle aging. PMID- 29168288 TI - Robotic Strong's procedure for the treatment of superior mesenteric artery syndrome. Description of surgical technique on occasion of the first reported case in the literature. AB - BACKROUND: Superior Mesenteric Artery Syndrome (SMAS) is a rare disorder caused by compression of the third portion of the duodenum by the SMA. Once a conservative approach fails, usual surgical strategies include Duodenojejunostomy and Strong's procedure. The latter avoids potential anastomotic risks and complications. Robotic Strong's procedure (RSP) combines both the benefits of a minimal invasive approach and also enchased robotic accuracy and efficacy. METHODS: For a young girl who was unsuccessfully treated conservatively, the paper describes the RSP surgical technique. To the authors' knowledge, this is the first report in the literature. RESULTS: Minimal blood loss, short operative time, short hospital stay and early recovery were the short-term benefits. Significant weight gain was achieved three months after the surgery. CONCLUSION: Based on primary experience, it is suggested that RSP is a very effective alternative in treating SMAS. PMID- 29168289 TI - Cannabinoids for nausea and vomiting related to chemotherapy: Overview of systematic reviews. AB - Nausea and vomiting are common and distressing adverse events of chemotherapy. This review focuses on the findings and quality of systematic reviews (SRs) of cannabinoids for chemotherapy-induced nausea and vomiting (CINV). Review of SRs, a systematic literature search, was conducted in several electronic databases and included SRs evaluating cannabinoids for CINV in cancer patients. Methodological quality and quality of reporting were evaluated by AMSTAR and PRISMA, respectively. Initial search retrieved 2,206 records, and 5 SRs were included. On the basis of findings of the sole SR judged as high methodological quality, cannabinoids seem to be more effective than placebo, equal to prochlorperazine for reducing CINV, and to be preferred by patients. The response to different combinations of antiemetic agents seems to be equal to 1 antiemetic alone. The average of AMSTAR score was 5, and the average of PRISMA score was 13.2. Cannabinoids represent a valuable option for treating CINV, despite the adverse events related to treatment, such as drowsiness and cognitive impairment. There is no good quality evidence to recommend or not the use of cannabinoids for CINV. More studies are still needed to evaluate the effectiveness of cannabinoids when compared with modern antiemetics. PMID- 29168291 TI - The COL5A3 and MMP9 genes interact in eczema susceptibility. AB - BACKGROUND: Genetic studies of eczema have identified many genes, which explain only 14% of the heritability. Missing heritability may be partly due to ignored gene-gene (G-G) interactions. OBJECTIVE: Our aim was to detect new interacting genes involved in eczema. METHODS: The search for G-G interaction in eczema was conducted using a two-step approach, which included as a first step, a biological selection of genes, which are involved either in the skin or epidermis development or in the collagen metabolism, and as a second step, an interaction analysis of the selected genes. Analyses were carried out at both SNP and gene levels in three asthma-ascertained family samples: the discovery dataset of 388 EGEA (Epidemiological study on the Genetics and Environment of Asthma) families and the two replication datasets of 253 SLSJ (Saguenay-Lac-Saint-Jean) families and 207 MRCA (Medical Research Council) families. RESULTS: One pair of SNPs, rs2287807 in COL5A3 and rs17576 in MMP9, that were detected in EGEA at P <= 10-5 showed significant interaction by meta-analysis of EGEA, SLSJ and MRCA samples (P = 1.1 * 10-8 under the significant threshold of 10-7 ). Gene-based analysis confirmed strong interaction between COL5A3 and MMP9 (P = 4 * 10-8 under the significant threshold of 4 * 10-6 ) by meta-analysis of the three datasets. When stratifying the data on asthma, this interaction remained in both groups of asthmatic and non-asthmatic subjects. CONCLUSION: This study identified significant interaction between two new genes, COL5A3 and MMP9, which may be accounted for by a degradation of COL5A3 by MMP9 influencing eczema susceptibility. Further confirmation of this interaction as well as functional studies is needed to better understand the role of these genes in eczema. PMID- 29168292 TI - Evaluation of the effect of quercetin treatment on CYP2C9 enzyme activity of diclofenac in healthy human volunteers. AB - The purpose of present study was to evaluate the effect of quercetin on pharmacokinetics of diclofenac sodium (DIC) in healthy volunteers. The open label, 2 period, sequential study was conducted in 12 healthy volunteers. DIC 100 mg was administered during control and after quercetin phases. Quercetin 500 mg was administered twice daily for 10 days during quercetin phase. Treatment with quercetin significantly enhanced maximum plasma concentration (Cmax ), area under the curve (AUC0-infinity ), and half life, while significantly decreased elimination rate constant (kel ) and apparent oral clearance (CL/F) of DIC compared with control. On the other hand, Cmax and AUC0-infinity of 4 hydroxydiclofenac (4-OHDIC) were decreased after quercetin treatment. In addition, geometric mean ratios and 90% confidence intervals for Cmax and AUC0 infinity of DIC and 4-OHDIC were both out of the no-effect limits of 0.80-1.25, which indicates a significant pharmacokinetic interaction between quercetin and DIC. Furthermore, quercetin treatment significantly decreased metabolic ratios of Cmax and AUC0-infinity suggesting that reduced formation of DIC to 4-OHDIC. The results suggest that quercetin might have inhibited CYP2C9-mediated metabolism of DIC. Accordingly, caution should be taken when quercetin is used in combination with therapeutic drugs metabolized by CYP2C9, and dose adjustment of CYP2C9 substrates may be necessary.

AB - Mercury and its compounds possess strong neurotoxicity and patients with mercury poisoning often report pain and numbness in the distal extremities that conform to the "stocking-glove" pattern. However, no study has investigated whether damage to small nerve fibers is associated with mercury poisoning. The aims of the present study were to evaluate the effects of different doses of mercury chloride (HgCl2 ) on intraepidermal nerve fibers density (IENFD) and Langerhans cells (LCs) in the plantar skin of rats and to assess the possible relationship between changes in IENFD and sensory testing. Male Sprague-Dawley rats were divided into three experimental groups and administered HgCl2 solutions via gavage at three different doses (4.25, 8.5, and 17 mg/kg/day) for 21 days. Subsequently, behavioral tests and pathological changes in IENFD and LCs were assessed at three different time points (1, 2, and 3 weeks). Rats in all three HgCl2 groups exhibited varying degrees of weight and hair loss. Thermal hypersensitivity was evident in all the HgCl2 groups (for middle-2w subgroup, p < 0.05). Mechanical sensitivity tests revealed hyposensitivity in all the HgCl2 groups except the high-1w subgroup. Significant decreases in IENFD (for the high 1w, middle-1w, low-2w, and low-3w subgroups, p < 0.05) and significant increases in the density of LCs (except for the low-1w and high-2w subgroups, all p < 0.05) were found in all groups after HgCl2 exposure. An association analysis revealed a significant correlation between the decrease in IENFD and the increase in LCs densities (r = -0.573, p < 0.01). The present study demonstrated a decrease in IENFD and an increase in LCs density in the plantar skin of rats after HgCl2 poisoning, indicating that damage of the small nerve fibers occurs after mercury poisoning. PMID- 29168290 TI - Gating the holes in the Swiss cheese (part I): Expanding professor Reason's model for patient safety. AB - INTRODUCTION: Although patient safety has improved steadily, harm remains a substantial global challenge. Additionally, safety needs to be ensured not only in hospitals but also across the continuum of care. Better understanding of the complex cognitive factors influencing health care-related decisions and organizational cultures could lead to more rational approaches, and thereby to further improvement. HYPOTHESIS: A model integrating the concepts underlying Reason's Swiss cheese theory and the cognitive-affective biases plus cascade could advance the understanding of cognitive-affective processes that underlie decisions and organizational cultures across the continuum of care. METHODS: Thematic analysis, qualitative information from several sources being used to support argumentation. DISCUSSION: Complex covert cognitive phenomena underlie decisions influencing health care. In the integrated model, the Swiss cheese slices represent dynamic cognitive-affective (mental) gates: Reason's successive layers of defence. Like firewalls and antivirus programs, cognitive-affective gates normally allow the passage of rational decisions but block or counter unsounds ones. Gates can be breached (ie, holes created) at one or more levels of organizations, teams, and individuals, by (1) any element of cognitive-affective biases plus (conflicts of interest and cognitive biases being the best studied) and (2) other potential error-provoking factors. Conversely, flawed decisions can be blocked and consequences minimized; for example, by addressing cognitive biases plus and error-provoking factors, and being constantly mindful. Informed shared decision making is a neglected but critical layer of defence (cognitive affective gate). The integrated model can be custom tailored to specific situations, and the underlying principles applied to all methods for improving safety. The model may also provide a framework for developing and evaluating strategies to optimize organizational cultures and decisions. LIMITATIONS: The concept is abstract, the model is virtual, and the best supportive evidence is qualitative and indirect. CONCLUSIONS: The proposed model may help enhance rational decision making across the continuum of care, thereby improving patient safety globally.

PMID- 29168295 TI - Lean psoas area does not correlate with clinical outcomes in moderately to severely injured older people. AB - OBJECTIVE: Frailty has been associated with worse outcomes in older trauma patients. Specifically, the utility of lean cross-sectional psoas muscle area (LPA) was examined as a potentially simple objective measure of frailty. METHODS: Five hundred and fifty-four patients over the age of 65 were admitted with trauma between 2011 and 2014. Two hundred and twenty-five of these had adequate computed tomography imaging available for analysis. Cross-sectional area of the psoas muscle at the inferior endplate of L4 was quantified. RESULTS: Multivariate regression analysis showed no significant correlation between LPA and outcomes of mortality (P = 0.82) or inpatient complications (P = 0.22). Injury Severity Score (ISS) had a strong association with both mortality (odds ratio (OR) 9.5; 95% confidence interval (CI) 2.9-30.9) and inpatient complications (OR 9.9; 95% CI 3.5-27.7). Age also had an association with mortality (OR 1.09; 95% CI 1.03-1.16) and inpatient complications (OR 1.06; 95% CI 1.01-1.12). CONCLUSION: Lean psoas area was not an independent predictor of mortality or complications in a cohort of injured older patients. PMID- 29168294 TI - Association of prenatal folate status with early childhood wheeze and atopic dermatitis. AB - BACKGROUND: Prenatal folic acid supplementation is recommended to prevent birth defects. Some foods are fortified in the USA to ensure sufficient intake among reproductive-aged women. However, high prenatal folate exposure may be a risk factor for childhood atopic diseases. We investigated associations between prenatal folate and early childhood wheeze and atopic dermatitis in a US cohort. METHODS: We studied 858 mother-child dyads, enrolled prenatally. Folate was measured in 2nd and 3rd trimester maternal plasma. Parents reported current wheeze (previous 12 months) and healthcare provider diagnosis of atopic dermatitis at 3 years. We examined associations using logistic regression, modeling folate continuously and dichotomously (< or >=20 ng/mL), a level often considered supraphysiologic. RESULTS: Over half of women were African American and on Medicaid. Median (interquartile range) folate levels were 22.6 (15.9-30.0) and 23.1 (16.1-30.0) ng/mL for 2nd and 3rd trimesters, respectively. Current wheeze and atopic dermatitis were reported for 20.4% and 26.8% of children, respectively. Second trimester folate as a continuous exposure was not significantly associated with outcomes. Decreased odds of current wheeze were observed in children born to mothers who had 2nd trimester folate >=20 ng/mL (adjusted odds ratios = 0.67, 95% confidence interval = 0.46, 0.97) compared to children with maternal levels <20 ng/mL. Third trimester folate was not associated with outcomes. CONCLUSIONS: High plasma folate in mid-pregnancy was associated with decreased odds of current wheeze at age 3. Our findings do not support harmful effects of high prenatal folate levels on childhood atopic diseases in this setting. PMID- 29168298 TI - Biallelic mutations in NALCN: Expanding the genotypic and phenotypic spectra of IHPRF1. AB - Loss-of function mutations in NALCN on chromosome 13q, a sodium leak channel that maintains baseline neuronal excitability, cause infantile hypotonia with psychomotor retardation and characteristic faces 1 (IHPRF1, OMIM #615419). Here, we document two individuals with early onset hypotonia with poor feeding and intellectual disability who were compatible with a diagnosis of IHPRF1. The two patients had bi-allelic mutations in NALCN through two different genetic mechanisms: Patient 1 had bi-allelic splice site mutations, that is c.1267-2A>G, derived from heterozygous parents, while Patient 2 had a partial maternal uniparental isodisomy that harbored a frameshift mutation, that is c.2022_2023delAT, in chromosome 13 that was detected through a dedicated algorithm for homozygosity data mapping in whole exome sequencing. The delineation of the exact pattern of inheritance provided vital information regarding the risk of recurrence. In animal models with Nalcn mutations, two behavioral phenotypes, that are, postnatal dyspnea and sleep disturbance, have been reported. Our observations of the two patients with postnatal dyspnea and one patient with sleep disturbance support an association between these two behavioral phenotypes and NALCN mutations in humans. The routine use of a detection algorithm for homozygosity data mapping might improve the diagnostic yields of next-generation sequencing. PMID- 29168297 TI - Single suture craniosynostosis: Identification of rare variants in genes associated with syndromic forms. AB - We report RNA-Sequencing results on a cohort of patients with single suture craniosynostosis and demonstrate significant enrichment of heterozygous, rare, and damaging variants among key craniosynostosis-related genes. Genetic burden analysis identified a significant increase in damaging variants in ATR, EFNA4, ERF, MEGF8, SCARF2, and TGFBR2. Of 391 participants, 15% were found to have damaging and potentially causal variants in 29 genes. We observed transmission in 96% of the affected individuals, and thus penetrance, epigenetics, and oligogenic factors need to be considered when recommending genetic testing in patients with nonsyndromic craniosynostosis. PMID- 29168299 TI - 17alpha-estradiol acts through hypothalamic pro-opiomelanocortin expressing neurons to reduce feeding behavior. AB - Weight loss is an effective intervention for diminishing disease burden in obese older adults. Pharmacological interventions that reduce food intake and thereby promote weight loss may offer effective strategies to reduce age-related disease. We previously reported that 17alpha-estradiol (17alpha-E2) administration elicits beneficial effects on metabolism and inflammation in old male mice. These observations were associated with reduced calorie intake. Here, we demonstrate that 17alpha-E2 acts through pro-opiomelanocortin (Pomc) expression in the arcuate nucleus (ARC) to reduce food intake and body mass in mouse models of obesity. These results confirm that 17alpha-E2 modulates appetite through selective interactions within hypothalamic anorexigenic pathways. Interestingly, some peripheral markers of metabolic homeostasis were also improved in animals with near complete loss of ARC Pomc transcription. This suggests that 17alpha-E2 might have central and peripheral actions that can beneficially affect metabolism cooperatively or independently.

PMID- 29168301 TI - Animal models used in furcation perforation studies: A systematic review and comprehensive synthesis of model characteristics. AB - In order to systematise furcation perforation (FP) experimental animal models described in the literature and to determine whether there is evidence that a model is superior to others, MEDLINE/PubMed, SciELO and Cochrane Library were searched to find studies which used animal models of FP. Data were gathered concerning model characteristics, chosen groups, sample numbers, type of outcomes, journal and main area studied. Twenty-five articles were included in this systematic review, four conducted in rodent models, three in non-human primates and 18 in dogs. Medians were six animals and 34 teeth per study; 10 teeth per test group and, when performed, six teeth per control group. Twenty four studies investigated the use of materials for FP repair; eight also tested adjuvant materials/substances. Although there is no model which can be described as ideal and superior than others for FP studies, dogs appear to possess the most suitable model characteristics. PMID- 29168302 TI - Analysing and Navigating Natural Products Space for Generating Small, Diverse, But Representative Chemical Libraries. AB - Armed with the digital availability of two natural products libraries, amounting to some 195 885 molecular entities, we ask the question of how we can best sample from them to maximize their "representativeness" in smaller and more usable libraries of 96, 384, 1152, and 1920 molecules. The term "representativeness" is intended to include diversity, but for numerical reasons (and the likelihood of being able to perform a QSAR) it is necessary to focus on areas of chemical space that are more highly populated. Encoding chemical structures as fingerprints using the RDKit "patterned" algorithm, we first assess the granularity of the natural products space using a simple clustering algorithm, showing that there are major regions of "denseness" but also a great many very sparsely populated areas. We then apply a "hybrid" hierarchical K-means clustering algorithm to the data to produce more statistically robust clusters from which representative and appropriate numbers of samples may be chosen. There is necessarily again a trade off between cluster size and cluster number, but within these constraints, libraries containing 384 or 1152 molecules can be found that come from clusters that represent some 18 and 30% of the whole chemical space, with cluster sizes of, respectively, 50 and 27 or above, just about sufficient to perform a QSAR. By using the online availability of molecules via the Molport system (www.molport.com), we are also able to construct (and, for the first time, provide the contents of) a small virtual library of available molecules that provided effective coverage of the chemical space described. Consistent with this, the average molecular similarities of the contents of the libraries developed is considerably smaller than is that of the original libraries. The suggested libraries may have use in molecular or phenotypic screening, including for determining possible transporter substrates. PMID- 29168303 TI - Fall risk assessment tools for use among older adults in long-term care settings: A systematic review of the literature. AB - OBJECTIVE: To conduct a systematic review of published fall risk assessment tools (FRATs) tested for predictive validity among older adults in long-term care (LTC). METHODS: A systematic search was conducted using five databases. Only studies reporting on sensitivity and specificity values, conducted in LTC on populations primarily aged over 60 years, were considered. RESULTS: Fifteen papers were included and three different categories of FRATs emerged: multifactorial assessment tools, functional mobility assessments and algorithms. Several FRATs showed moderate-to-good predictive validity and reliability, with the Modified Fall Assessment Tool and the Peninsula Health Falls Risk Assessment Tool (PHFRAT) also demonstrating good feasibility. CONCLUSION: Evidence for the best choice of FRAT for use in LTC remains limited. Further research is warranted for the PHFRAT, recommended for use in LTC by best practice guidelines, before its establishment as the tool of choice for these clinical settings. PMID- 29168304 TI - Aboriginal children and penicillin injections for rheumatic fever: how much of a problem is injection pain? AB - OBJECTIVE: To explore young Aboriginal people's and clinicians' experiences of injection pain for the 10 years of penicillin injections children are prescribed to prevent rheumatic fever recurrences. METHODS: Aboriginal children on the penicillin regimen and clinicians were purposively recruited from four remote sites in Australia. Semi-structured interviews and participant observations were conducted. Views were synthesised and thematically analysed. RESULTS: A total of 29 Aboriginal children and 59 clinicians were interviewed. Sixteen participants appeared to become accustomed to the injection pain, eight did not find pain an issue, and five found injection pain difficult. A further five believed the injections made them unwell. Patients expressed varying abilities to negotiate with clinicians about the use of pain reduction measures. Clinicians revealed good knowledge of pain reduction measures, but offered them inconsistently. All clinicians found administering the injections distressing. CONCLUSION: Repeated painful procedures in children necessitate well-planned and child-focused care. Current practices are not in line with guidance from the Royal Australasian College of Physicians about effects of repeated painful procedures on children. Initiating the long-term injection regimen for rheumatic fever is a special event requiring expert input. A newly reported finding of a subset of young people feeling unwell after receiving the injection requires further investigation. Implications for public health: Improvement of local and jurisdictional guidelines on use of pain reduction measures for children who have been prescribed repeated painful injections for rheumatic fever is needed. PMID- 29168305 TI - The Trajectory of Anhedonic and Depressive Symptoms in Anorexia Nervosa: A Longitudinal and Cross-Sectional Approach. AB - Anhedonia, the inability to experience pleasure, is associated with depression, schizophrenia and also anorexia nervosa (AN). However, it remains unanswered whether anhedonic symptoms in AN are undernutrition-dependent depressive symptoms or a core feature of AN. Therefore, we aim at investigating the trajectory of anhedonic and depressive symptoms over the course of the disorder. Self-reported symptoms were collected in 35 nonmedicated acutely ill, 33 long-term recovered patients and 62 healthy females. The majority of the acutely ill (n = 24) were followed up after >15% weight restoration (short-term recovery). Anhedonia was found to be increased during the acute, short-term as well as long-term recovered state while depressive symptoms showed a reduction over time. Additionally, depressive symptoms were negatively associated with body mass index in acute patients. This provides evidence of anhedonia being a trait-characteristic of AN, relatively unrelated to undernutrition-dependent depressive symptoms. Results are discussed with regard to implications for treatment and prevention. Copyright (c) 2017 John Wiley & Sons, Ltd and Eating Disorders Association.

PMID- 29168307 TI - Optimising residential respite care in nursing homes: Current problems and solutions for a better future. AB - AIM: To examine whether residential respite care increases the risk of harm to older people and suggest directions for future research and policy. BACKGROUND: Respite care is a vital part of the aged care system that supports dependent older people and their caregivers to continue residing in the community. There is little research determining whether an older person experiences harm from residential respite. METHODS: This commentary considered conceptual research and existing empirical evidence to determine whether the risk of death was greater during residential respite care for older people. RESULTS: Evidence on the mortality in contemporary respite care is extremely limited with the majority of studies published almost 20 years ago and focussing on planned respite admissions. The evidence available has limitations in design and lacks comparison groups and key variables relevant to outcome and risk stratification. Nonetheless, it provides a theoretical basis supporting that the potential for harm and mortality may be increased during a residential respite care admission. CONCLUSIONS: The question of whether residential respite care presents significant risks to older people remains unanswered. Substantial changes in practice since the last century make the existing empirical evidence redundant. However, there is much to learn by reflecting on omissions of important details from these studies. IMPLICATIONS FOR PRACTICE: A full and objective understanding of the harm associated with residential respite care for older people requires reopening and re-examining this area with robust research. Informed professional nursing practice and policy requires an empirical evidence basis to residential respite care. PMID- 29168308 TI - Demonstrating Improved Multiple Transport-Mean-Free-Path Imaging Capabilities of Light Sheet Microscopy in the Quantification of Fluorescence Dynamics. AB - Optical microscopy constitutes, one of the most fundamental paradigms for the understanding of complex biological mechanisms in the whole-organism and live tissue context. Novel imaging techniques such as light sheet fluorescence microscopy (LSFM) and optical projection tomography (OPT) combined with phase retrieval algorithms (PRT) can produce highly resolved 3D images in multiple transport-mean-free-path scales. Our study aims to exemplify the microscopic capabilities of LSFM when imaging protein dynamics in Caenorhabditis elegans and the distribution of necrotic cells in cancer cell spheroids. To this end, we apply LSFM to quantify the spatio-temporal localization of the GFP-tagged aging and stress response factor DAF-16/FOXO in transgenic C. elegans. Our analysis reveals a linear nuclear localization of DAF-16::GFP across tissues in response to heat stress, using a system that outperforms confocal scanning fluorescent microscopy in imaging speed, 3D resolution and reduced photo-toxicity. Furthermore, we present how PRT can improve the depth-to-resolution-ratio when applied to image the far-red fluorescent dye DRAQ7 which stains dead cells in a T47D cancer cell spheroid recorded with a customized OPT/LSFM system. Our studies demonstrate that LSFM combined with our novel approaches enables higher resolution and more accurate 3D quantification than previously applied technologies, proving its advance as new gold standard for fluorescence microscopy. PMID- 29168309 TI - Soldier-biased gene expression in a subterranean termite implies functional specialization of the defensive caste. AB - In a termite colony, reproduction is typically monopolized by a small number of sexuals that are supported by reproductively altruistic soldiers and workers. We expect caste differentiation to be associated with clear-cut differences in gene expression, and for these differences to reflect caste function and development. Here, we use RNA-Sequencing to compare the gene expression profiles of sexual nymphs and two non-reproductive helper castes (i.e., workers and soldiers) of the Eastern subterranean termite Reticulitermes flavipes. We found that of n = 93 genes that are strictly expressed as a function of caste, a majority (78%) show a soldier-specific pattern. This conspicuous soldier-bias in genome-wide expression suggests that this defensively specialized caste is functionally well differentiated from both the reproductive and the other non-reproductive caste of this species, despite a shared developmental program with workers. Gene ontology analysis supports the notion of functional specialization by soldiers, as soldier biased gene sets are enriched for novel biological processes. Whether this pattern reflects ancient or more recent bouts of selection for caste novelty at the gene-regulatory level is not known, but because soldiers are sterile and thus have no direct fitness, any selection for novelty must have been mediated indirectly, through reproducing relatives. PMID- 29168310 TI - A pilot pharmacokinetic study of miroestrol and deoxymiroestrol on rabbit sera using polyclonal antibody-based icELISA analysis. AB - Miroestrol (ME) and deoxymiroestrol (DME) are the most potent phytoestrogens and bioactive markers in Pueraria candollei var. mirifica tuberous roots. To understand their pharmacokinetic profiles, a pharmacokinetic study of ME and DME, at 0.43 and 0.21 mg per kg body weight, respectively, in three rabbits was performed after orally administering a single dose of P. candollei var. mirifica enriched fraction extract. Two established polyclonal antibody-based indirect competitive enzyme-linked immunosorbent assays were validated to determine ME and DME in rabbit sera. In rabbits, the area under the 0- to 48-hr concentration-time curve of ME and DME were 854.92 and 1,692.84 ng.h/ml, respectively. The maximum concentration of ME was measured 1 hr after administration as 69.62 +/- 8.28 ng/ml, and the maximum concentration of DME was measured at 3 hr as 81.8 +/- 5.43 ng/ml. These results provide an initial approach for designing and studying the relationship between the ME and DME levels and their therapeutic effects based on their pharmacokinetic profiles. PMID- 29168311 TI - Usefulness of serum Wisteria floribunda agglutinin-positive Mac-2 binding protein in children with primary sclerosing cholangitis. AB - BACKGROUND: Wisteria floribunda agglutinin-positive Mac-2 binding protein (WFA+ M2BP) is a novel serum marker of hepatic fibrosis in adults with chronic hepatitis C. However, it remains unclear whether serum WFA+ -M2BP levels are associated with the progression of liver histology in primary sclerosing cholangitis (PSC). METHODS: Twenty-eight children and adolescents with pediatric onset PSC (male : female patient ratio, 20:8; median age at diagnosis, 9 years) were enrolled in this study. The relation between serum WFA+ -M2BP levels and clinical characteristics was retrospectively evaluated. Moreover, receiver operating characteristic (ROC) analysis was used to determine whether serum WFA+ M2BP levels could be a reliable marker to identify PSC patients with advanced liver histology. RESULTS: According to the Ludwig classification of liver histological stage, 28 patients were classified into the four stages. The WFA+ M2BP level, aspartate aminotransferase (AST) to platelet ratio index (APRI), and hyaluronic acid correlated significantly with liver histological stage. Moreover, WFA+ -M2BP showed a significant positive correlation (P < 0.05) with autoimmune hepatitis overlap, AST, alanine aminotransferase (ALT), gamma glutamyltransferase, total bilirubin, immunoglobulin G, APRI, and hyaluronic acid. A ROC analysis was undertaken to distinguish the patients with advanced stage disease (stage 3-4) from those with early stage disease (stage 0-2). It showed that WFA+ -M2BP yielded the highest area under the ROC curve value (0.898) among four surrogate makers (APRI, 0.850; Fibrosis-4 index, 0.806; and AST/ALT ratio, 0.802). Moreover, WFA+ -M2BP yielded the highest sensitivity, specificity, positive predictive value, and negative predictive value among the four markers. CONCLUSIONS: Serum WFA+ -M2BP levels are useful to identify patients with advanced liver histology in pediatric PSC. PMID- 29168312 TI - Curcumin mediated down-regulation of alphaV beta3 integrin and up-regulation of pyruvate dehydrogenase kinase 4 (PDK4) in Erlotinib resistant SW480 colon cancer cells. AB - Erlotinib is a potent, selective, and orally active inhibitor of the epidermal growth factor receptor, but the development of erlotinib resistance during chemotherapy can lead to treatment failure. To shed light on the erlotinib resistant pathway, this study investigated the effect of combination therapy using curcumin- and erlotinib-loaded nanoparticles on the expression of alphav beta3 integrin and pyruvate dehydrogenase kinase 4 (PDK4) in an erlotinib resistant SW480 colon cancer cell line. An erlotinib-resistant SW480 colon cancer cell line was produced by long-term exposure to erlotinib. Curcumin-loaded Methoxy poly ethylene glycol Poly caprolactone (cur/mPEG-PCL) and erlotinib loaded mPEG-PCL (erl/mPEG-PCL) micelles were provided using a single step nanoprecipitation method and used as combination therapy of resistant SW480 cancer cells. After that, gene expression levels of PDK4, alphav, and beta3 mRNA were determined by the semiquantitative reverse transcription-polymerase chain reaction. Protein levels of whole alphav beta3 integrin were evaluated using the enzyme-linked immunosorbent assay method. In SW480 cell line, the IC50 of nonresistant and resistant cells was 87.6 +/- 1.2 nM and 19.1 +/- 0.14 MUM, for erlotinib and it was about 21.8 and 30 MUM for curcumin, respectively. Although PDK4 expression was not significantly different in resistant and nonresistant cells, its expression was up regulated (1.4 fold) in resistant cells by a combination therapy of cur/mPEG-PCL at a dose of 3 MUM and erl/mPEG-PCL at a dose of 5 MUM. beta3 mRNA and the protein level of whole alphav beta3 integrin was significantly higher in resistant SW480 cells as compared with those in nonresistant cells. In terms of treatment, a combination of 6-MUM cur/mPEG-PCL and 5-MUM erl/mPEG-PCL down regulated beta3 gene expression 6.6-fold in resistant cells as compared with nonresistant cells. At the protein level, a combination of 3-MUM-cur/mPEG-PCL and 10-MUM erl/mPEG-PCL reduced alphav beta3 protein in resistant cells. The results indicated that combination therapy using cur/mPEG PCL and erl/mPEG-PCL could decrease alphav beta3 integrin expression and increase PDK4 gene expression in resistant colon cancer cells, which may have effects on drug resistance signaling pathways. PMID- 29168314 TI - Elevated plasma and vitreous levels of leucine-rich-alpha2-glycoprotein are associated with diabetic retinopathy progression. AB - PURPOSE: To investigate the association of plasma and vitreous leucine-rich alpha2-glycoprotein (LRG1) with diabetic retinopathy (DR) progression. METHODS: A total of 86 outpatients and 33 inpatients were recruited. Outpatients with type 2 diabetes mellitus (T2DM) were classified as T2DM without DR (n = 22), nonproliferative DR (NPDR) (n = 20) and proliferative DR (PDR) (n = 22) based on international clinical DR severity scales. A total of 86 plasma and 33 vitreous samples were collected and subjected to enzyme-linked immunosorbent assay. The diagnostic value of plasma LRG1 was tested using receiver operating characteristic (ROC) curves. RESULTS: Plasma LRG1 in PDR patients (9025 +/- 1870 pg/ml) was significantly increased as compared with controls (5975 +/- 2022 pg/ml), T2DM without DR (6550 +/- 2359 pg/ml) and NPDR patients (6550 +/- 2359 pg/ml) (p < 0.0001). Vitreous LRG1 in PDR patients was elevated by approximately 4.3-fold than that in controls (562.1 +/- 273.5 ng/ml versus 130.0 +/- 102.8 ng/ml, p = 0.000). The area under the ROC curve value for plasma LRG1 was 0.786 (p < 0.0001). The maximal Youden index was 0.4372 and the optimal cut-off value of LRG1 was 7357.043 pg/ml with 81.82% sensitivity and 61.90% specificity. CONCLUSION: Plasma and vitreous LRG1 levels were elevated in patients with PDR. Leucine-rich-alpha2-glycoprotein (LRG1) might be a potential risk-warning marker for PDR. PMID- 29168313 TI - Children with blindness - major causes, developmental outcomes and implications for habilitation and educational support: a two-decade, Swedish population-based study. AB - PURPOSE: The aim was to describe the population of children with congenital or early infancy blindness in Sweden, with regard to causes of blindness and prevalence of neurodevelopmental impairments. METHODS: Medical, psychological and pedagogical records of Swedish children with congenital or early infancy blindness (total blindness or light perception at the most) born in 1988-2008 were analysed regarding year of birth, gender, cause of blindness, gestational age, associated neurological disorders/syndromes, associated neurodevelopmental impairments, cognitive level and type of school placement. RESULTS: A total of 150 individuals, 80 girls and 70 boys, were identified, corresponding to a prevalence of 7/100 000. Five causes of blindness dominated, constituting 76% of all represented aetiologies: retinopathy of prematurity (ROP), optic nerve hypoplasia (ONH), Leber congenital amaurosis (LCA), optic nerve atrophy (ONA) and microphthalmia/anophthalmia. Nearly three of four children in the study population had at least one additional disability besides blindness; the most common being intellectual disability (ID) and autism spectrum disorder (ASD). More than half of the population had more than one additional disability. Autism spectrum disorder (ASD) was most common in children with ONH, ROP, LCA and microphthalmia/anophthalmia. CONCLUSION: In children born within the last decades, isolated blindness is uncommon and the rate of multidisabilities is high. Autism spectrum disorder (ASD) seems to be more strongly associated with specific aetiological subgroups. Further development of the support to families and schools should be based on knowledge about the considerable heterogeneity of the population of children with blindness, and the common occurrence of coexisting neurodevelopmental disorders, especially ID and ASD.

PMID- 29168317 TI - Hepatitis C virus prevalence and associated risk factors among Indigenous Australians who inject drugs. AB - OBJECTIVE: To examine factors associated with hepatitis C virus (HCV) infection among a national sample of Indigenous and non-Indigenous people who inject drugs (PWID) in Australia. METHODS: Respondents were recruited from Australia's Needle Syringe Program Survey; an annual bio-behavioural surveillance project that monitors HCV antibody prevalence among PWID. Data from 2006-2015 were de duplicated to retain only one record where individuals participated in >1 survey round. Univariate and multivariable logistic regression examined demographic characteristics and injection-related behaviours associated with exposure to HCV. RESULTS: Among 17,413 respondents, 2,215 (13%) were Indigenous Australians. Compared to their non-Indigenous counterparts, Indigenous respondents were significantly more likely to be exposed to HCV infection (53% vs. 60% respectively, p<0.001). Among Indigenous respondents, HCV antibody positivity was independently associated with a history of imprisonment (Adjusted Odd Ratio [AOR] 2.13, 95%CI 1.73-2.64), opioid injection (AOR 1.53, 95%CI 11.43-2.16), recruitment in a metropolitan location (AOR 1.27, 95%CI 1.02-1.59), engagement in opioid substitution therapy (AOR 2.83, 95%CI 2.23-3.59) and length of time since first injection (p<0.001). CONCLUSION: Indigenous PWID are more likely to be exposed to HCV infection than their non-Indigenous counterparts. Implications for public health: Increased access to culturally sensitive harm reduction programs is required to prevent primary HCV infection and reinfection among Indigenous PWID. Given recent advances in HCV treatment, promotion of treatment uptake among Indigenous PWID may reduce future HCV-related morbidity and mortality. PMID- 29168318 TI - Validation of X-ray Wavefunction Refinement. AB - In this work, the quality of the electron density in crystals reconstructed by the multipolar model (MM) and by X-ray wavefunction refinement (XWR) is tested on a set of high-resolution X-ray diffraction data sets of four amino acids and six tripeptides. It results in the first thorough validation of XWR. Agreement statistics, figures of merit, residual- and deformation-density maps, as well as atomic displacement parameters are used to measure the quality of the reconstruction relative to the measured structure factors. Topological analysis of the reconstructed density is carried out to obtain atomic and bond-topological properties, which are subsequently compared to the values derived from benchmarking periodic DFT geometry optimizations. XWR is simultaneously in better agreement than the MM with both benchmarking theory and the measured diffraction pattern. In particular, the obvious problems with the description of polar bonds in the MM are significantly reduced by using XWR. Similarly, modeling of electron density in the vicinity of hydrogen atoms with XWR is visibly improved. PMID- 29168316 TI - Outer dense fibers stabilize the axoneme to maintain sperm motility. AB - Outer dense fibers (ODFs), as unique accessory structures in mammalian sperm, are considered to play a role in the protection of the sperm tail against shear forces. However, the role and relevant mechanisms of ODFs in modulating sperm motility and its pathological involvement in asthenozoospermia were unknown. Here, we found that the percentage of ODF defects was higher in asthenozoospermic samples than that in control samples and was significantly correlated with the percentage of axoneme defects and non-motile sperm. Furthermore, the expression levels of ODF major components (Odf1, 2, 3, 4) were frequently down-regulated in asthenozoospermic samples. Intriguingly, the positive relationship between ODF size and sperm motility existed across species. The conditional disruption of Odf2 expression in mice led to reduced sperm motility and the characteristics of asthenozoospermia. Meanwhile, the expression of acetylated alpha-tubulin was decreased in sperm from both Odf2 conditional knockout (cKO) mice and asthenozoospermic men. Immunofluorescence and biochemistry analyses showed that Odf2 could bind to acetylated alpha-tubulin and protect the acetylation level of alpha-tubulin in HEK293T cells in a cold environment. Finally, we found that lithium elevated the expression levels of Odf family proteins and acetylated alpha-tubulin, elongated the midpiece length and increased the percentage of rapidly moving sperm in mice. Our results demonstrate that ODFs are beneficial for sperm motility via stabilization of the axoneme and that hypo-expression of Odf family proteins is involved in the pathogenesis of asthenozoospermia. The lithium administration assay will provide valuable insights into the development of new treatments for asthenozoospermia. PMID- 29168319 TI - Hospital-based routine HIV testing in high-income countries: a systematic literature review. AB - OBJECTIVES: To produce a summary of the published evidence of the barriers and facilitators for hospital-based routine HIV testing in high-income countries. METHODS: Electronic databases were searched for studies, which described the offer of HIV testing to adults attending emergency departments (EDs) and acute medical units (AMUs) in the UK and US, published between 2006 and 2015. Other high-income countries were not included, as their guidelines do not recommend routine testing for HIV. The main outcomes of interest were HIV testing uptake, HIV testing coverage, factors facilitating HIV screening and barriers to HIV testing. Fourteen studies met the pre-defined inclusion criteria and critically appraised using mixed methods appraisal tool (MMAT). RESULTS: HIV testing coverage ranged from 9.7% to 38.3% and 18.7% to 26% while uptake levels were high (70.1-84% and 53-75.4%) in the UK and US, respectively. Operational barriers such as lack of time, the need for training and concerns about giving results and follow-up of HIV positive results, were reported. Patient-specific factors including female sex, old age and low risk perception correlated with refusal of HIV testing. Factors that facilitated the offer of HIV testing were venous sampling (vs. point-of-care tests), commitment of medical staff to HIV testing policy and support from local HIV specialist providers. CONCLUSIONS: There are several barriers to routine HIV testing in EDs and AMUs. Many of these stem from staff fears about offering HIV testing due to the perceived lack of knowledge about HIV. Our systematic review highlights areas which can be targeted to increase coverage of routine HIV testing. PMID- 29168321 TI - Effect of fetal and infant growth on respiratory symptoms in preterm-born children. AB - OBJECTIVES: Fetal growth and rapid postnatal weight gain are associated with adverse respiratory outcomes in childhood. However, the preterm-born population is less well studied. We assessed if the increased respiratory symptoms associated with altered fetal growth and infant weight gain were mediated by early factors. STUDY DESIGN: We used data from our cohort of preterm- and term born (n = 4284 and 2865) children, aged 1-10 years. Respiratory outcomes obtained from a respiratory questionnaire were regressed on measures of fetal growth and infant weight gain, defined as >0.67 SD change in fetal measurement or weight between birth and nine months of age, then adjusted for covariates. We used mediation analysis to investigate which variables were effect modifiers. RESULTS: Accelerated fetal growth between the 1st trimester and birth (OR 2.01; 95%CI 1.25, 2.32), and between the 2nd trimester and birth (1.60; 1.15, 2.22) was associated with increased wheeze-ever in preterm-born children. Rapid infant weight gain was associated with increased wheeze-ever (1.22; 1.02, 1.45); children born <=32 weeks' gestation exhibiting rapid weight gain had fivefold higher risk of wheeze-ever compared to term-born without weight gain. Current maternal smoking and gestational age were identified as candidate mediating effects. CONCLUSIONS: Our study suggested that antenatal and postnatal growth rates are important for future respiratory health in preterm-born children, and that their effects may be mediated by modifiable factors. Minimizing exposure to environmental pollutants, especially maternal tobacco smoking, may improve outcomes. PMID- 29168320 TI - Pulmonary hypertension in the premature infant population: Analysis of echocardiographic findings and biomarkers. AB - OBJECTIVE: Extremely low gestational age neonates (ELGANs) are at risk for pulmonary hypertension (PH). We hypothesized that PH, defined by echocardiogram at 36 weeks gestational age (GA), would associate with respiratory morbidity, increased oxidant stress, and reduced nitric oxide production. STUDY DESIGN: ELGANs in the Vanderbilt fraction of the Prematurity and Respiratory Outcomes Program (PROP) who had echocardiograms at 36 +/- 1 weeks GA were studied. Echocardiogram features of PH were compared with clinical characteristics as well as markers of oxidant stress and components of the nitric oxide pathway. Biomarkers were obtained at enrollment (median day 3), 7, 14, and 28 days of life. RESULTS: Sixty of 172 infants had an echocardiogram at 36 weeks; 11 had evidence of PH. Infants did not differ by PH status in regards to demographics, respiratory morbidity, or oxidant stress. However, odds of more severe PH were significantly higher in infants with higher nitric oxide metabolites (NOx) at enrollment and with a lower citrulline level at day 7. CONCLUSIONS: Respiratory morbidity may not always associate with PH at 36 weeks among ELGANs. However, components of nitric oxide metabolism are potential biologic markers of PH in need of further study. PMID- 29168322 TI - Biosynthetically Guided Structure-Activity Relationship Studies of Merochlorin A, an Antibiotic Marine Natural Product. AB - The onset of new multidrug-resistant strains of bacteria demands continuous development of antibacterial agents with new chemical scaffolds and mechanisms of action. We present the first structure-activity relationship (SAR) study of 16 derivatives of a structurally novel antibiotic merochlorin A that were designed using a biosynthetic blueprint. Our lead compounds are active against several Gram-positive bacteria such as Staphylococcus aureus (SA), methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus faecium (VRE) and Bacillus subtilis, inhibit intracellular growth of Mycobacterium bovis, and are relatively nontoxic to human cell lines. Furthermore, derivative 12 c {(+/-) (3aR,4S,5R,10bS)-5-bromo-7,9-dimethoxy-4-methyl-4-(4-methylpent-3-en-1-yl)-2 (propan-2-ylidene)-1,2,3,3a,4,5-hexahydro-6H-5,10b-methanobenzo[e]azulene-6,11 dione} was found to inhibit the growth of Bacillus Calmette-Guerin (BCG)-infected cells at concentrations similar to rifampicin. These results outperform the natural product, underscoring the potential of merochlorin analogues as a new class of antibiotics. PMID- 29168323 TI - Disability-based discrimination and health: findings from an Australian-based population study. AB - OBJECTIVE: Among working-age Australian adults with a disability, we assess the association between disability-based discrimination and both overall health and psychological distress. METHODS: Using data from the 2015 Australian Bureau of Statistics Survey of Disability, Ageing and Carers we estimated the proportion of working-age women and men (15-64 years) with disability who report disability based discrimination by socio-demographic characteristics and assessed the association between disability-based discrimination and self-reported health and psychological distress. RESULTS: Nearly 14% of Australians with disability reported disability-based discrimination in the previous year. Disability-based discrimination was more common among people living in more disadvantaged circumstances (unemployed, low income, lower-status occupations), younger people and people born in English-speaking countries. Disability-based discrimination was associated with higher levels of psychological distress (OR: 2.53, 95%CI: 2.11, 3.02) and poorer self-reported health (OR: 1.63, 95%CI: 1.37, 1.95). CONCLUSION: Disability-based discrimination is a prevalent, important determinant of health for Australians with disability. Implications for public health: Disability-based discrimination is an under-recognised public health problem that is likely to contribute to disability-based health inequities. Public health policy, research and practice needs to concentrate efforts on developing policy and programs that reduce discrimination experienced by Australians with disability. PMID- 29168324 TI - Environmental levels of avian antigen are relevant to the progression of chronic hypersensitivity pneumonitis during antigen avoidance. AB - BACKGROUND: In chronic hypersensitivity pneumonitis (chronic HP), antigen avoidance is critical for disease management; however, complete avoidance is difficult because of unrecognized exposure to antigens. Recently, we revealed that the amount of avian antigen (AAA) in household dust at the time of diagnosis predicted the progression of chronic bird-related HP. The purpose of this study is to evaluate the relationship between the prognosis of chronic bird-related HP and the AAA that remained in the environment during antigen avoidance. METHODS: First, we measured the AAA in household dust of 28 consecutive patients (22 with chronic bird-related HP and 6 with acute bird-related HP) and 12 healthy volunteers. Second, we measured the AAA and collected questionnaires on the environmental conditions of the homes of 53 patients with various lung diseases, including bird-related HP, to investigate the environmental parameters related to a higher AAA. Finally, we prospectively recruited 14 consecutive patients with chronic bird-related HP, measured the AAA periodically, and collected clinical data. RESULTS: The AAA was higher in patients with chronic bird-related HP at the time of diagnosis compared to healthy volunteers and was highest in patients with acute bird-related HP. Logistic regression analysis showed that birds frequenting a residence was the only significant factor for a higher AAA (odds ratio, 5.686; 95%CI, 1.263-25.59; P = 0.024). There was a correlation between the mean AAA and decline of vital capacity for 1 year (r = -0.55; 95%CI -0.84 to -0.01; P = 0.043). CONCLUSION: Measurements of the AAA after diagnosis predict the progression of chronic bird-related HP. Avian antigen can exist in the indoor environment regardless of antigen avoidance. The presence of avian antigen in the indoor environment can be attributed to wild birds found outdoors.

PMID- 29168328 TI - Coating of optical fiber with a smart thermosensitive polymer for the separation of phthalate esters by solid-phase microextraction. AB - A solid-phase microextraction fiber was prepared by coating an optical fiber with a temperature-sensitive polymer to determine phthalate esters. N Isopropylacrylamide and N,N'-methylenebisacrylamide were used as the monomer and the cross linker, respectively. The fabricated fiber was characterized by FTIR spectroscopy, thermogravimetric analysis, and scanning electron microscopy. During extraction, important factors such as extraction time, pH, temperature, and ionic strength were optimized. The fabricated fiber, which is firm, inexpensive, stable, and efficient, is a vital material used in solid-phase microextraction. Under optimum conditions, the calibration curve was linear and in the range of 1-20 MUg/L (r2 = 0.9747). The high extraction efficiency was obtained for phthalates with a detection limit of 0.12 MUg/L. The fabricated fiber was successfully applied to the solid-phase micro extraction of phthalates from water samples after its extraction, followed by gas chromatography with flame ionization detection. PMID- 29168326 TI - Guidelines in CHARGE syndrome and the missing link: Cranial imaging. AB - "CHARGE syndrome" is a complex syndrome with high and extremely variable comorbidity. As a result, clinicians may struggle to provide accurate and comprehensive care, and this has led to the publication of several clinical surveillance guidelines and recommendations for CHARGE syndrome, based on both single case observations and cohort studies. Here we perform a structured literature review to examine all the existing advice. Our findings provide additional support for the validity of the recently published Trider checklist. We also identified a gap in literature when reviewing all guidelines and recommendations, and we propose a guideline for neuroradiological evaluation of patients with CHARGE syndrome. This is of importance, as patients with CHARGE are at risk for peri-anesthetic complications, making recurrent imaging procedures under anesthesia a particular risk in clinical practice. However, comprehensive cranial imaging is also of tremendous value for timely diagnosis, proper treatment of symptoms and for further research into CHARGE syndrome. We hope the guideline for neuroradiological evaluation will help clinicians provide efficient and comprehensive care for individuals with CHARGE syndrome.

PMID- 29168327 TI - Distinct cerebellar foliation anomalies in a CHD7 haploinsufficient mouse model of CHARGE syndrome. AB - Mutations in the gene encoding the ATP dependent chromatin-remodeling factor, CHD7 are the major cause of CHARGE (Coloboma, Heart defects, Atresia of the choanae, Retarded growth and development, Genital-urinary anomalies, and Ear defects) syndrome. Neurodevelopmental defects and a range of neurological signs have been identified in individuals with CHARGE syndrome, including developmental delay, lack of coordination, intellectual disability, and autistic traits. We previously identified cerebellar vermis hypoplasia and abnormal cerebellar foliation in individuals with CHARGE syndrome. Here, we report mild cerebellar hypoplasia and distinct cerebellar foliation anomalies in a Chd7 haploinsufficient mouse model. We describe specific alterations in the precise spatio-temporal sequence of fissure formation during perinatal cerebellar development responsible for these foliation anomalies. The altered cerebellar foliation pattern in Chd7 haploinsufficient mice show some similarities to those reported in mice with altered Engrailed, Fgf8 or Zic1 gene expression and we propose that mutations or polymorphisms in these genes may modify the cerebellar phenotype in CHARGE syndrome. Our findings in a mouse model of CHARGE syndrome indicate that a careful analysis of cerebellar foliation may be warranted in patients with CHARGE syndrome, particularly in patients with cerebellar hypoplasia and developmental delay.

PMID- 29168332 TI - Associative role of HLA-DRB1 SNP genotypes as risk factors for susceptibility and severity of rheumatoid arthritis: A North-east Indian population-based study. AB - Rheumatoid arthritis (RA) is a complex, multifactorial, systemic autoimmune disease. Reports are suggestive of the role of HLA especially HLA-DRB1 alterations in RA pathogenesis. Existing data involving different geographical populations on the role of alterations in specific locus of HLA-DRB1 in RA susceptibility and severity are equivocal, with no data available from ethnically distinct North-east Indian population, where RA cases are alarmingly increasing. This study aimed to evaluate the association of HLA-DRB1 gene SNPs (rs13192471, rs660895 and rs6457617) with susceptibility and severity of RA in an ethnically distinct North-east Indian population. Whole blood was collected from clinically characterized RA cases (satisfying the American College of Rheumatology 1987 criteria) (n = 123) and community-based age and sex-matched healthy controls (n = 156) with informed consent. The HLA-DRB1 SNP analysis was performed for all the RA and control cases using ARMS-PCR using case and control genomic DNA as template. Statistical analysis was performed by SPSSv13.0 software. The HLA-DRB1 rs660895 showed both wild (AA) and heterozygote (AG) genotype but the heterozygote allele was found to be associated with reduced risk of RA compared to controls [OR = 0.531, p = .024]. The difference in distribution of rs6457617 polymorphism between RA and control cases was comparable [OR = 0.525, p = .079]. Significantly higher distribution of variant rs13192471 genotype was observed in RA cases (69.92%) compared to controls (46.75%) (p < .001) and was associated with increased risk of susceptibility to RA [OR = 2.576, p < .001] compared to controls, as well as progression to severity in RA cases [OR = 2.404, p = .048]. Combinatorially also, the presence of rs13192471 variant genotype was associated with increased risk of RA susceptibility [OR = 8.267, p = .026] and RA severity [OR = 3.647, p = .280]. Alterations in HLA-DRB1 are associated with RA susceptibility. HLA-DRB1 rs13192471 SNP plays a critical role in RA susceptibility and severity in North-east Indian cases and has prognostic significance in RA.

AB - To investigate the prognostic value of PD-L1 expression combined with CD8+ TILs density in patients with resected NSCLC and correlations with clinicopathological features. We retrospectively enrolled 178 patients with resected NSCLC from 2011 to 2015. All surgical primary and 58 matched metastatic lymph node specimens were tested for PD-L1, CD8+ TILs, and oncogenic alterations. PD-L1+ was detected in 71 (39.9%) and CD8high TILs in 74 (41.6%) cases. Smoking, SqCC, and EGFR- were associated with both PD-L1+ and CD8high TILs. Patients with CD8high TILs had longer OS (P = 0.012). PD-L1- was significantly associated with longer OS in patients with oncogenic alterations (P = 0.047). By multivariate analysis, CD8high TILs (HR = 0.411; 95% CI, 0.177-0.954; P = 0.038), rather than PD-L1, was the independent predictive factor for OS. The longest and shortest OS were achieved in patients with PD-L1+ /CD8high and PD-L1+ /CD8low , respectively (P = 0.025). Inconsistent PD-L1 expression levels were observed in 23 of 58 (39.7%) patients with primary and matched metastatic lymph node specimens. Of them, CD8high TILs was significantly associated with longer OS in patients with metastatic lymph nodes and/or consistent PD-L1 expression (P = 0.017 and 0.049, respectively). The combination of PD-L1 and CD8+ TILs density, instead of PD-L1 alone, suggested impressive prognostic values in NSCLC patients. Less than half of patients with resected NSCLC experienced inconsistent PD-L1 expression between primary and metastatic lesions. The level of PD-L1 expression in advanced NSCLC needs to be evaluated more comprehensively. PMID- 29168341 TI - Introducing the 6-4-0 fasting regimen and the incidence of prolonged preoperative fasting in children. AB - BACKGROUND: Children often starve for longer than recommended by current preoperative fasting guidelines. AIMS: We studied the effects of implementing a more lenient fasting regimen on the duration of clear fluid fasting, as well as the incidence of extended fasting in children. METHODS: Preoperative duration of clear fluid fasting was recorded for patients scheduled for procedures in a unit applying the standard 6-4-2 fasting regimen. This group was compared with a cohort in the same unit 1 year after transitioning to a 6-4-0 fasting regimen. The latter includes no limitations on clear fluid intake until the child is called to theater. A third cohort from a unit in which the 6-4-0 fasting regimen has been implemented for over a decade was also studied for comparison. RESULTS: Patients fasting according to the 6-4-2 fasting regimen (n = 66) had a median fasting time for clear fluids of 4.0 h and a 33.3% incidence of fasting more than 6 h. After transitioning to the 6-4-0 fasting regimen (n = 64), median duration of fasting for clear fluids decreased to 1.0 h, and the incidence of fasting more than 6 h decreased to 6.3%. In the second unit (n = 73), median fasting time was 2.2 h and the proportion of patients fasting more than 6 h was 21.9%. CONCLUSION: The introduction and implementation of the 6-4-0 fasting regimen reduces median fluid fasting duration and the number of children subjected to extended fasting. PMID- 29168340 TI - Hyperoxia induces paracellular leak and alters claudin expression by neonatal alveolar epithelial cells. AB - BACKGROUND: Premature neonates frequently require oxygen supplementation as a therapeutic intervention that, while necessary, also exposes the lung to significant oxidant stress. We hypothesized that hyperoxia has a deleterious effect on alveolar epithelial barrier function rendering the neonatal lung susceptible to injury and/or bronchopulmonary dysplasia (BPD). MATERIALS AND METHODS: We examined the effects of exposure to 85% oxygen on neonatal rat alveolar barrier function in vitro and in vivo. Whole lung was measured using wet to-dry weight ratios and bronchoalveolar lavage protein content and cultured primary neonatal alveolar epithelial cells (AECs) were measured using transepithelial electrical resistance (TEER) and paracellular flux measurements. Expression of claudin-family tight junction proteins, E-cadherin and the Snail transcription factor SNAI1 were measured by Q-PCR, immunoblot and confocal immunofluorescence microscopy. RESULTS: Cultured neonatal AECs exposed to 85% oxygen showed impaired barrier function. This oxygen-induced increase in paracellular leak was associated with altered claudin expression, where claudin-3 and -18 were downregulated at both the mRNA and protein level. Claudin-4 and -5 mRNA were also decreased, although protein expression of these claudins was largely maintained. Lung alveolarization and barrier function in vivo were impaired in response to hyperoxia. Oxygen exposure also significantly decreased E cadherin expression and induced expression of the SNAI1 transcription factor in vivo and in vitro. CONCLUSIONS: These data support a model in which hyperoxia has a direct impact on alveolar tight and adherens junctions to impair barrier function. Strategies to antagonize the effects of high oxygen on alveolar junctions may potentially reverse this deleterious effect. PMID- 29168342 TI - Sphingosine-1-phosphate (S1P) enhances glomerular endothelial cells activation mediated by anti-myeloperoxidase antibody-positive IgG. AB - Cumulating evidences suggested an important role of sphingosine-1-phosphate (S1P) and its receptors in regulating endothelial barrier integrity. Our previous study revealed that the circulating S1P levels and renal expression of S1PRs correlated with disease activity and renal damage in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). This study investigated the role of S1P and its receptors in myeloperoxidase (MPO)-ANCA-positive IgG mediated glomerular endothelial cell (GEnC) activation. The effect of S1P on morphological alteration of GEnCs in the presence of MPO-ANCA-positive IgG was observed. Permeability assay was performed to determine endothelial monolayer activation in quantity. Both membrane-bound and soluble ICAM-1 and VCAM-1 levels were measured. Furthermore, antagonists and/or agonists of various S1PRs were employed to determine the role of different S1PRs. S1P enhanced MPO-ANCA-positive IgG-induced disruption of tight junction and disorganization of cytoskeleton in GEnCs. S1P induced further increase in monolayer permeability of GEnC monolayers in the presence of MPO-ANCA-positive IgG. S1P enhanced MPO-ANCA-positive IgG induced membrane-bound and soluble ICAM-1/VCAM-1 up-regulation of GEnCs. Soluble ICAM-1 levels in the supernatants of GEnCs stimulated by S1P and MPO-ANCA positive IgG increased upon pre-incubation of S1PR1 antagonist, while pre incubation of GEnCs with the S1PR1 agonist down-regulated sICAM-1 level. Blocking S1PR2-4 reduced sICAM-1 levels in the supernatants of GEnCs stimulated by S1P and MPO-ANCA-positive IgG. Pre-incubation with S1PR5 agonist could increase sICAM-1 level in the supernatants of GEnC stimulated by S1P and MPO-ANCA-positive IgG. S1P can enhance MPO-ANCA-positive IgG-mediated GEnC activation through S1PR2-5. PMID- 29168343 TI - Lipocalin 2 (Lcn2) interferes with iron uptake by Brucella abortus and dampens immunoregulation during infection of RAW 264.7 macrophages. AB - Lipocalin 2 (Lcn2) is an important innate immunity component against bacterial pathogens. In this study, we report that Lcn2 is induced by Brucella (B.) abortus infection and significantly contributes to the restriction of intracellular survival of Brucella in macrophages. We found that Lcn2 prevented iron uptake by B. abortus through two distinct mechanisms. First, Lcn2 is secreted to capture bacterial siderophore(s) and abrogate iron import by Brucella. Second, Lcn2 decreases the intracellular iron levels during Brucella infection, which probably deprives the invading Brucella of the iron source needed for growth. Suppression of Lcn2 signalling resulted in a marked induction of anti-inflammatory cytokine, interleukin 10, which was shown to play a major role in Lcn2-induced antibrucella immunity. Similarly, interleukin 6 was also found to be increased when Lcn2 signalling is abrogated; however, this induction was thought to be an alternative pathway that rescues the cell from infection when the effective Lnc2 pathway is repressed. Furthermore, Lcn2 deficiency also caused a marked decrease in brucellacidal effectors, such as reactive oxygen species and nitric oxide but not the phagolysosome fusion. Taken together, our results indicate that Lcn2 is required for the efficient restriction of intracellular B. abortus growth that is through limiting iron acquisition and shifting cells to pro-inflammatory brucellacidal activity in murine macrophages.

Trabecular bone specimens from porcine femurs were loaded under a uniaxial compression experimentally and computationally. The apparent behaviors computed using von Mises, Drucker-Prager, and Cast Iron plasticity models were compared. Secondly, the effect of bone volume fraction was studied by changing the bone volume fraction of a trabecular bone sample while keeping the same basic architecture. Also, constitutive models' parameters of the tissue were calibrated for porcine bone, and the effects of different parameters on resulting apparent response were investigated through a parametric study. The calibrated effective tissue elastic modulus of porcine trabecular bone was 10+/-1.2 GPa, which is in the lower range of modulus values reported in the literature for human and bovine trabecular bones (4-23.8 GPa). It was also observed that, unlike elastic modulus, yield properties of tissue could not be uniquely calibrated by fitting an apparent response from simulations to experiments under a uniaxial compression. Our results demonstrated that using these 3 tissue constitutive models had only a slight effect on the apparent response. As expected, there was a significant change in the apparent response with varying bone volume fraction. Also, both apparent modulus and maximum stress had a linear relation with bone volume fraction.

AB - Piwi-like RNA-mediated gene silencing 1 (PIWIL1) has been identified as a novel extremely highly expressed cancer-testis (CT) gene in lung adenocarcinoma. However, the exact function and mechanism of PIWIL1 in lung adenocarcinoma remains unclear. Herein, we sought to investigate the role of PIWIL1 in the occurrence and development of lung adenocarcinoma. We examined the expression pattern of PIWIL1 in The Cancer Genome Atlas (TCGA) lung adenocarcinoma samples, and validated it by Real-Time PCR (RT-PCR) in additional 21 paired lung adenocarcinoma tissues and 16 normal tissues. Subsequently, we explored the biological function of PIWIL1 in A549 and H1299 cell lines by gain and loss-of function analyses. Using TCGA lung adenocarcinoma data, we further performed coexpression and Gene Ontology (GO) analyses, and analyzed the association of DNA methylation levels in PIWIL1 promoter region with its expression. Finally, we evaluated its expression in different mutation status of significantly mutated genes (SMGs) in TCGA lung adenocarcinoma data. We observed that PIWIL1 was expressed in testis and lung adenocarcinoma but not in other normal tissues, and its high expression was associated with shortened survival of lung cancer patients. Overexpression of PIWIL1 could facilitate the proliferation, invasion and migration of lung adenocarcinoma cells and vice versa. GO analysis revealed that PIWIL1 upregulated genes were enriched in embryonic development, cell proliferation and regulation of transcription. Moreover, promoter DNA hypomethylation of PIWIL1 could contribute to its aberrant expression in tumors. Interestingly, PIWIL1 expression was significantly higher in patients without hepatocyte growth factor (HGF) or serine/threonine kinase 11 (STK11) mutation (P = 0.006 and 0.005, respectively). PIWIL1 is an epidriver gene in lung adenocarcinoma, indicating a potential target for further therapy. PMID- 29168349 TI - Bioactive Pimarane Diterpenes from the Arctic Fungus Eutypella sp. D-1. AB - Two new pimarane diterpenes, libertellenone M (1) and libertellenone N (2), together with five known compounds were isolated from the culture extract of Eutypella sp. D-1 derived from high-latitude soil of the Arctic. The structures of these compounds were determined by spectroscopic data as well as experimental and calculated electronic circular dichroism (ECD) analysis. Antimicrobial and cytotoxic activities of the isolated compounds were evaluated. Compound 3 exhibited weak antibacterial activity against Escherichia coli, Bacillus subtilis, and Vibrio vulnificus, each with MIC values of 16 MUg/mL. Compounds 2 and 3 showed moderate cytotoxic activity against K562 and MCF-7 cell lines with IC50 values of 7.67 and 9.57 MUm, respectively. PMID- 29168352 TI - Patient satisfaction with information on oral anticancer agent use. AB - Adequate information on oral anticancer agent (OACA) use is an essential element of optimal cancer care. The present study aimed to get insight into the experiences of patients with information on OACA treatment and their characteristics regarding information dissatisfaction. Patients of four Dutch university hospitals using OACA participated in this observational study and completed the Satisfaction with Information about Medicines Scale (SIMS), EORTC Quality of Life Questionnaire-C30, Brief Illness Perception Questionnaire, and Beliefs about Medicines Questionnaire-Specific. Logistic regression analyses were used to determine factors associated with dissatisfaction with information. Patients (n = 208) using capecitabine (35%), lenalidomide (15%), imatinib (14%), temozolomide (12%), sunitinib (11%), thalidomide (5%), dasatinib (4%), erlotinib (2%), and nilotinib (2%) participated. Information on the following SIMS-items was inadequate: how OACA elicit their effect, how long it takes before treatment works, how to conclude that treatment is effective, the risk of side effects and its management, interference with sex life, drowsiness, interference with other medication and alcohol and what to do in case of a missed dose. Younger age, hematological malignancy, dyspnoea, positive perception of consequences of the cancer, low perception of treatment control, and indifferent attitude towards OACA were associated with dissatisfaction with information. In conclusion, a considerable number of patients would have appreciated receiving more information on specific issues relating to the consequences of OACA treatment such as the effects and side effects of OACA and the interference of treatment with various aspects of their daily life. Oncologists, hematologists, lung-oncologists and pharmacists may reconsider the provision of information on OACA treatment. PMID- 29168351 TI - Complement 5a-mediated trophoblasts dysfunction is involved in the development of pre-eclampsia. AB - Pre-eclampsia (PE) is a life-threatening multisystem disorder leading to maternal and neonatal mortality and morbidity. Emerging evidence showed that activation of the complement system is implicated in the pathological processes of PE. However, little is known about the detailed cellular and molecular mechanism of complement activation in the development of PE. In this study, we reported that complement 5a (C5a) plays a pivotal role in aberrant placentation, which is essential for the onset of PE. We detected an elevated C5a deposition in macrophages and C5a receptor (C5aR) expression in trophoblasts of pre-eclamptic placentas. Further study showed that C5a stimulated trophoblasts towards an anti-angiogenic phenotype by mediating the imbalance of angiogenic factors such as soluble fms like tyrosine kinase 1 (sFlt1) and placental growth factor (PIGF). Additionally, C5a inhibited the migration and tube formation of trophoblasts, while, C5aR knockdown with siRNA rescued migration and tube formation abilities. We also found that maternal C5a serum level was increased in women with PE and was positively correlated with maternal blood pressure and arterial stiffness. These results demonstrated that the placental C5a/C5aR pathway contributed to the development of PE by regulating placental trophoblasts dysfunctions, suggesting that C5a may be a novel therapeutic possibility for the disease. PMID- 29168350 TI - Breakpoint mapping and haplotype analysis of translocation t(1;12)(q43;q21.1) in two apparently independent families with vascular phenotypes. AB - BACKGROUND: The risk of serious congenital anomaly for de novo balanced translocations is estimated to be at least 6%. We identified two apparently independent families with a balanced t(1;12)(q43;q21.1) as an outcome of a "Systematic Survey of Balanced Chromosomal Rearrangements in Finns." In the first family, carriers (n = 6) manifest with learning problems in childhood, and later with unexplained neurological symptoms (chronic headache, balance problems, tremor, fatigue) and cerebral infarctions in their 50s. In the second family, two carriers suffer from tetralogy of Fallot, one from transient ischemic attack and one from migraine. The translocation cosegregates with these vascular phenotypes and neurological symptoms. METHODS AND RESULTS: We narrowed down the breakpoint regions using mate pair sequencing. We observed conserved haplotypes around the breakpoints, pointing out that this translocation has arisen only once. The chromosome 1 breakpoint truncates a CHRM3 processed transcript, and is flanked by the 5' end of CHRM3 and the 3' end of RYR2. TRHDE, KCNC2, and ATXN7L3B flank the chromosome 12 breakpoint. CONCLUSIONS: This study demonstrates a balanced t(1;12)(q43;q21.1) with conserved haplotypes on the derived chromosomes. The translocation seems to result in vascular phenotype, with or without neurological symptoms, in at least two families. We suggest that the translocation influences the positional expression of CHRM3, RYR2, TRHDE, KCNC2, and/or ATXN7L3B.

PMID- 29168353 TI - Genomic risk prediction of aromatase inhibitor-related arthralgia in patients with breast cancer using a novel machine-learning algorithm. AB - Many breast cancer (BC) patients treated with aromatase inhibitors (AIs) develop aromatase inhibitor-related arthralgia (AIA). Candidate gene studies to identify AIA risk are limited in scope. We evaluated the potential of a novel analytic algorithm (NAA) to predict AIA using germline single nucleotide polymorphisms (SNP) data obtained before treatment initiation. Systematic chart review of 700 AI-treated patients with stage I-III BC identified asymptomatic patients (n = 39) and those with clinically significant AIA resulting in AI termination or therapy switch (n = 123). Germline DNA was obtained and SNP genotyping performed using the Affymetrix UK BioBank Axiom Array to yield 695,277 SNPs. SNP clusters that most closely defined AIA risk were discovered using an NAA that sequentially combined statistical filtering and a machine-learning algorithm. NCBI PhenGenI and Ensemble databases defined gene attribution of the most discriminating SNPs. Phenotype, pathway, and ontologic analyses assessed functional and mechanistic validity. Demographics were similar in cases and controls. A cluster of 70 SNPs, correlating to 57 genes, was identified. This SNP group predicted AIA occurrence with a maximum accuracy of 75.93%. Strong associations with arthralgia, breast cancer, and estrogen phenotypes were seen in 19/57 genes (33%) and were functionally consistent. Using a NAA, we identified a 70 SNP cluster that predicted AIA risk with fair accuracy. Phenotype, functional, and pathway analysis of attributed genes was consistent with clinical phenotypes. This study is the first to link a specific SNP/gene cluster to AIA risk independent of candidate gene bias.

Single institution experience on cancer among adolescents 15-19 years of age. Turk J Pediatr 2017; 59: 1-5. Adolescent cancers differ from other age groups in terms of cancer types, treatment and outcome. We aimed to present our institutional data on survival of certain types of cancer in adolescents. Hospital files were retrospectively evaluated for distribution of tumor types, clinical features, and overall and event-free survival (OS and EFS) rates in adolescents with malignant tumors. Two hundred ninety-three cases between 15-19 years who were diagnosed with malignant tumor at our department in the last 38 years were included in the study. Mean age was 15.3 and median age was 15 years at time of diagnosis. Male/female ratio was found to be 1.8/1. The most common cancers were non-Hodgkin lymphoma (NHL) (20.5%), Hodgkin's lymphoma (HL) (19.8%), central nervous system (CNS) tumors (10.9%), osteosarcoma (10.6%), Ewing sarcoma/primitive neuroectodermal tumors (EWN/PNET (9.9%) nasopharyngeal carcinoma (NPC) (9.6%). Non-compliance to medical treatment was observed in 10.9% of cases with significantly high non-compliance in NHL and osteosarcoma (p=0.02). Overall survival was 57.6% and EFS was 45.7% at a median follow-up time of 8.75 years. In adolescents, lower OS and EFS rates than the younger age group are observed. The most appropriate management plan should be made according to the physical and psychosocial needs of patients in this age group.

Turk J Pediatr 2017; 59: 6-12. Methotrexate (MTX) is the most commonly used disease modifying anti-rheumatic drug in juvenile idiopathic arthritis (JIA). We aimed to define predictor factors for response to MTX in Turkish children with oligo- and polyarticular JIA. We reviewed the medical files of 59 oligo- and 57 polyarticular JIA patients seen in the clinic between May 2008 and May 2013 and who received MTX for >=6 months. MTX responders were defined as having no/low disease activity according to juvenile arthritis disease activity score 71 (JADAS71) at 6 months after MTX initiation. Median age at JIA diagnosis/MTX initiation was 70/78 months. Involvement of the small or upper extremity joints at disease diagnosis and MTX initiation was more frequent; antinuclear antibody (ANA) positivity was less frequent; acute phase reactants, JADAS71 at MTX initiation, and the frequency of polyarticular subtype were higher in MTX non-responders. In multiple logistic regression, oligoarticular JIA subtype and ANA positivity were independent predictors of MTX response.

The effects of routine administration of probiotics on the length of central venous line usage in extremely premature infants. Turk J Pediatr 2017; 59: 20-27. The objective of this study was to determine whether the routine use of probiotics was associated with earlier removal of peripherally inserted central catheter (PICC) lines in extremely premature infants born <=28 weeks' gestation. This study was a retrospective, observational, cohort study in infants born <=28 weeks gestation in the 2 years before [No Probiotic Group (NPG)] and after [Probiotic Group (PG)] the commencement of the routine use of probiotics (lnfloran(r)) in a large tertiary neonatal intensive care unit in the North Island of New Zealand. Age at the removal of PICC line in patients whose first PICC lines were inserted before day 14 and remained in-situ for at least 4 days was compared using Kaplan-Meir Survival Analysis on SPSS 22.0(r). We studied PICC line infections as a secondary outcome measure. We compared 120 PICC lines in NPG and 130 PICC lines in PG. Mean age at removal was 25.9 [(95% Confidence Intervals (CI)=22.6 - 29.2)] days in NPG and 23.1 (95% CI=20.9 - 25.2) days in PG. The result was independent of birth weight, gender, type of PICC line and age at insertion but related significantly to gestation at birth (p < 0.001). There was no difference in the incidence or the microbiologic profile of PICC line infections between the study groups. PICC lines were removed 2.8 days earlier in infants receiving probiotics (p=0.070), which can have potential benefits with reduced infection and other risks due to earlier removal of PICC lines.

The effect of early administration of combined multi-strain and multi-species probiotics on gastrointestinal morbidities and mortality in preterm infants: A randomized controlled trial in a tertiary care unit. Turk J Pediatr 2017; 59: 13-19. Necrotizing enterocolitis (NEC) is a gastrointestinal emergency of the neonatal period. The aim of this study was to demonstrate the use of multistrain and multispecies probiotic on gastrointestinal morbidities and mortality. The study was organized as a randomized controlled, prospective study in premature infants (<=32 week and <=1500 gram). The ready commercial preparations which contain multi-combined probiotics of Lactobacillus rhamnosus (4.1x108 cfu) + Lactobacillus casei (8.2x108 cfu) + Lactobacillus plantorum (4.1x108 cfu) + Bifidobacterium animalis (4.1x108 cfu) together with 383 mg of fructooligosaccharides and 100 mg of galactooligosaccharides as the prebiotic content, was administered enterally to the probiotic group (n=70); control group constituted of 40 preterms. Primary outcomes of the present study were >= Stage 2 NEC and the mortality. Secondary outcomes were culture-proven sepsis and days to reach full enteral feeding. All cases of NEC were seen in group 2 as 3.6% (n=4) of all infants. The mortality was found to be 1.4% (n=1) in Group 1 and 22.5% (n=9) in Group 2. The incidence of NEC and the mortality rate were found to be significantly lower in Group 1 (p=0.016, p=0.001, respectively). In Group 1, the NEC-related mortality rate and sepsis-related mortality rate were significantly lower than that of the control group (p=0.046, p=0.023). In this study, we showed that using probiotic strains in combined multistrain and multispecies forms at higher doses and for prolonged duration had positive effects on gastrointestinal complications, sepsis and mortality in premature infants.

Does Nissen fundoplication improve deglutition in children? Turk J Pediatr 2017; 59: 28-34. A prospective study was performed to evaluate the effect of Nissen fundoplication (NF) on deglutition in children. Children who underwent NF between 2011-2015 were evaluated for demographic features, clinical findings, diagnostic methods for gastroesophageal reflux (GER) and indications for NF. Penetration aspiration scale (PAS), functional oral intake scale (FOIS) and esophageal functions were evaluated by videoflouroscopy (VFS). Preoperative and postoperative VFS findings were compared to evaluate the effect of NF on clinical findings and deglutition. Twenty-three children with a mean age of 5.08 +/- 3.7 years were included. Female to male ratio was 15:8. Recurrent respiratory infections (RTI) (n: 14, 60.8%), swallowing dysfunction (n:13, 56.5%) and vomiting (n:10, 43.4%) were the most common symptoms. Preoperatively GER was diagnosed with barium swallowing study (BSS) contrast graphs (n:20, 87%) and with 24-hour esophageal pH monitorization (n:8, 34.8%). In 39.1% of patients, medical treatment for GER was used with a mean duration of 8 +/- 5.8 months. Indications for NF were swallowing dysfunction (n: 18, 78%), GER complications (n:6, 26%), associated anatomical problems (n:4, 17.3%) and unresponsiveness to medical treatment (n: 3, 13%). Postoperative barium swallowing study and 24-hour esophageal pH monitorization showed no GER after NF in 95% of patients. Number of RTI were significantly decreased after NF (preoperative vs postoperative infection rate 4.21 vs 1.6 respectively, p < 0.05). VFS findings showed that PAS was significantly decreased after NF during both liquid and semi-liquid swallowing (p < 0.05). After NF, upper esophageal opening (UEO) was decreased when compared to preoperative VFS findings (p < 0.05 Esophageal cleaning, esophageal motility, esophageal backflow and lower esophageal sphincter narrowing did not alter after NF (p > 0.05). FOIS were significantly improved after NF (p < 0.05). VFS findings showed that penetration and aspiration were significantly decreased after NF and children had less RTI. Although, esophageal motility evaluated by VFS did not changed after NF, functional oral intake significantly improved in children.

Hypophosphatemia associated risk factors in pediatric intensive care patients. Turk J Pediatr 2017; 59: 35-41. The aim of this work is to determine the prevalence and risk factors of hypophosphatemia in pediatric patients admitted to intensive care unit. The study was performed prospectively in patients admitted to the Pediatric Intensive Care Unit between June 2014 and December 2014. Fifty-seven patients were included in the study. The mean age of the study population was 24 months (2-192 months); 25 patients (43.9%) were male and 32 were female (56.1%). The mean body weight z-score was 1.47 +/- 2.23, and 23 (40.4%) patients had malnutrition. On admission 16 (28.1%) patients had hypophosphatemia. There were no statistically significant differences between the hypophosphatemic patient group and normophosphatemic patient groups in terms of demographic and clinical characteristics. There were also no significant differences between the two groups in terms of risk factors. Potassium and creatinine levels were significantly lower in the hypophosphatemic group, compared to the normophosphatemic group. According to a multivariate logistic regression analysis, risk factors for hypophosphatemia were low potassium level (OR: 16.76; 95% CI: 2.09 - 134.72; p: 0.008), malignant solid tumors (OR: 52.40; 95% CI: 2.04 - 1,344.32; p: 0.017, p: 0.036). and female gender (OR: 6.18; 95% CI: 1.12 - 34.00; p: 0.036). Prospective studies with larger sample size should be conducted to study the prevalence and risk factors of hypophosphatemia at pediatric intensive care unit.

The objective of this study is to examine the right and left ventricular functions in children with episodic wheezing at the ages of 1-3 exposed to environmental tobacco smoke (ETS). Thirty-two children monitored at the Pediatric Allergy and Immunology Department of a Research and Training Hospital with the diagnosis of episodic wheezing were included. The prospective assessment of the patients was performed between May 2013 and February 2014. Twenty-five children with episodic wheezing not exposed to ETS formed the control group. The two groups were compared by conducting transthoracic two-dimensional and tissue Doppler echocardiography (TDE) examination in all of the cases. The average age of the study group (24 boys, 8 girls) was 33.1 +/- 8.8 months, the average age of the control group (18 boys, 7 girls) was 31.9 +/- 11.9 months. There was no statistically significant difference between the two groups in terms of age, gender, weight, height, and body mass index values. There was no statistically significant difference between the two groups for the right and left ventricular systolic and diastolic functions in the conventional echocardiographic measurements, and for the measurements of TDE. Limited number of patients is a major limitation of the study. These results should be supported by more comprehensive studies.

Free estradiol index levels associated with high sensitivitiy CRP levels in male children. Turk J Pediatr 2017; 59: 49-55. Biomarkers of inflammation such as high-sensitivity C-reactive protein (hs-CRP) associate with subclinical atherosclerosis. Atherosclerosis is an early onset disease in life. Sex hormones and puberty modulate metabolism in children. Studies indicate that low sex hormone binding globulin (SHBG) levels associate with insulin resistance and metabolic syndrome in children. The aim of this study is to study the correlation between sex hormones and hs-CRP levels in children and adolescents. The study sample was derived from a cross sectional survey on the prevalence of cardiovascular risk factors in a representative sample of school children (8-17 year-old) in Istanbul, Turkey. In addition to anthropometric and biochemical characteristics of cardiovascular risk, sex hormones such as free androgen index, free estradiol index (FEI), SHBG and hs-CRP levels were measured in all study participants: 91 boys (12.4 +/- 3.4 years) and 77 girls (12.7 +/- 3.4 years) were included in the study. Median (interquartile range) hs-CRP levels were similar among boys and girls [0.36 (0.9) versus 0.45 (0.7) mg/dl, p= 0.725]. Gender stratified analysis displayed that hs-CRP levels positively correlated with FEI levels (r=0.438, p < 0.001) in boys. Linear regression analysis was performed to determine the predictors of hs-CRP. Among covariates of FEI, homeostasis model assessment-estimated insulin resistance, body mass index, age, and SHBG; FEI was shown to significantly and independently predict hs-CRP levels in boys [beta=2.758, p < 0.001, 95% confidence interval (CI) for beta 1.471-4.045]. FEI levels associate with subclinical inflammation in boys. Future studies may elucidate the role of sex hormone levels in inflammation among children.

Evaluation of choroidal thickness measurements in pediatric obstructive sleep apnea syndrome patients. Turk J Pediatr 2017; 59: 62 67. Choroidal vascular impairment and obstructive sleep apnea syndrome (OSAS) related disorders have been shown in adults, but there have been no investigations with regard to the choroidal thickness measurements in children with OSAS. Our aim was to investigate this relationship in the early childhood period, which correlates with OSAS peak incidence due to adenotonsillar enlargement. One-hundred and nine pediatric OSAS patients and 42 age-sex matched controls were enrolled in this study. Nocturnal pulse oximetry was used to define the OSAS patients. Demographic data like age, sex and body-mass index were recorded. All of the subjects underwent complete otolaryngologic and ophthalmologic examination including visual acuity, intraocular pressure, central corneal thickness, axial length and choroidal thickness measurements. Overall, the 1,000 MUm and 1,500 MUm nasal choroid measurements were found to be significantly lower in the patient group (p < 0.05). However, only a poor inverse correlation emerged between the body-mass index (BMI) and the foveal center measurements in the patients. Observed alterations in the choroid may signify the initial impairment of known OSAS-related eye disorders, like glaucoma, floppy eyelid syndrome, and non-arteritic ischemic optic neuropathy. Ophthalmologists, otolaryngologists and pediatricians working together as a team may be able to prevent future eye diseases.

The mutation of the PTEN gene that is responsible for controlling cellular proliferation, migration and apoptosis clarifies the reason of tissue overgrowth in BRRS. Gastrointestinal tract involvement is seen 35-45% of the patients. Histologic features of polyps in BRRS resemble juvenile polyps. In this report, we describe a boy presenting with hematochezia and aggressive polyposis and finally was diagnosed as BRRS due to extra intestinal findings.

Although gastrointestinal involvement does not belong to the classic diagnostic criteria; diarrhea, abdominal pain, hepatic dysfunction, hydrops of gallbladder, and acute febrile cholestatic jaundice are reported in patients with Kawasaki disease. We describe here two cases presented with fever, and acute jaundice as initial features of Kawasaki disease. PMID- 29168371 TI - Congenital insensitivity to pain: How should anesthesia be managed? AB - Ozmete O, Sener M, Bali C, Caliskan E, Aribogan A. Congenital insensitivity to pain: How should anesthesia be managed? Turk J Pediatr 2017; 59: 87-89. Congenital insensitivity to pain syndrome is a rare, sensorial and autonomic neuropathy characterized by unexplained fever, insensitivity to pain and anhidrosis. Patients may require anesthesia even for minor surgical procedures due to mental retardation and trauma arising from self- mutilating behavior. A child diagnosed with congenital insensitivity to pain syndrome was scheduled for gastric endoscopy under sedation due to suspected ingestion of a household cleaning disinfectant. Deep sedation was achieved, and spontaneous respiration was maintained. We did not encounter any complications. There is limited data regarding the safe anesthesia management in these patients because of the rarity of the disease. Therefore, we think that more clinical experience, case reports and studies are needed to establish the appropriate anesthesia management.

Tuba-ovarian auto amputation caused by ovarian teratoma in an adolescent girl. Turk J Pediatr 2017; 59: 90-92. Ovarian auto-amputation is an extremely rare condition commonly encountered in the perinatal period. Spontaneous or secondary torsion of the ovary caused by an ovarian lesion may result in infarction and subsequent auto amputation of the ovary. This paper demonstrates a case that underwent laparoscopic appendectomy with an incidental calcified auto-amputated right ovary. A 16-year-old adolescent girl was admitted to our department with a history of one-day abdominal pain. Physical examination of the patient revealed abdominal tenderness and rigidity on right lower quadrant. Her white blood cell count was 11x103/mL, and C-reactive protein was 69 mg/L. The patient underwent a laparoscopic appendectomy with a provisional diagnosis of acute appendicitis, and further exploration revealed a 2x2 cm white ovoid mass floating freely in the pelvis. The left ovary was clearly identified in its usual localization, but the right tuba was blindly ending without any fimbria or ovary. Postoperative course of the patient was uneventful, and she was discharged on postoperative day 2. The histopathological examination revealed a necrotic calcified ovarian teratoma. Auto-amputated ovary is a rare occasion mostly encountered during perinatal period, and it may be unilateral or bilateral. An auto-amputated ovarian mass may rarely be a teratoma although the most common cause of auto-amputation during perinatal and adolescent period is ovarian torsion due to an ovarian cyst.

Kocuria kristinae-caused sepsis in an infant with congenital tufting enteropathy. Turk J Pediatr 2017; 59: 93-96. Congenital tufting enteropathy (CTE) is characterized by the early-onset of chronic diarrhea and the inability to develop. It is a rare congenital disease with a low prevalence of 1:50,000 - 100,000 live births p.a. The histopathology is characterized by villous atrophy and the characteristic epithelial tufts. Recent identification of causative mutations in EpCAM has enhanced our understanding of this disease. Due to its severe clinical course, patients are dependent on parenteral nutrition to thrive successfully. Catheter-associated blood stream infections have become the primary problem for pediatric patients. Infections with Kocuria kristinae are rare. This report is about a 3-month-old girl with CTE suffering from a central venous catheter related mono-sepsis by K. kristinae. A sepsis therapy with meropenem and vancomycin improved her general state rapidly. Only few cases in the literature with CTE and K. kristinae are described. To the best of our knowledge, this is the first report presenting two coincidences in one case. PMID- 29168374 TI - Foreign body punctured the spleen: An incidental diagnosis. AB - Inal-Aslan G, Otgun I, Guney LH, Hicsonmez A. Foreign body punctured the spleen: An incidental diagnosis. Turk J Pediatr 2017; 59: 97-99. A foreign body can enter the body via penetration through the skin. In the presented case, a broken syringe needle was found and removed from the splenic parenchyma. In order to prevent such iatrogenic injuries, which could have fatal consequences, the hospital staff must give particular care in the handling of sharp FBs. PMID- 29168375 TI - Cholestasis and hypercalcemia secondary to panhypopituitarism in a newborn. AB - Dursun F, Gerenli N, Kirmizibekmez H. Cholestasis and hypercalcemia secondary to panhypopituitarism in a newborn. Turk J Pediatr 2017; 59: 100-103. Cholestatic hepatitis and hypercalcemia are rare features of hypopituitarism in newborns. So diagnosis of hypopituitarism is frequently delayed. The most frequent symptoms of congenital hypopituitarism are hypoglycemia, prolonged jaundince and micropenis. A patient with congenital hypopituitarism associated with cholestasis and hypercalcemia is reported here. Newborns with hypercalcemia and cholestasis should alert pediatricians to the possibility of congenital hypopituitarism and prompt endocrinological investigation. PMID- 29168377 TI - Universal Porphyrinic Metal-Organic Framework Coating to Various Nanostructures for Functional Integration. AB - A universal strategy was reported that enables functional group-capped nanostructures with various morphologies and compositions to be coated by porphyrin metal-organic framework (MOF). Based on the nanostructure-induced heterogeneous nucleation, the controlled growth of MOF shell on the surface of nanostructures can be realized. It was demonstrated that this modification strategy can realize controlled growth of porphyrin MOF on a series of organic and inorganic nanostructures, such as polydopamine (PDA) nanoparticles, PDA@Pt nanoparticles, graphene oxide sheets, and Au nanorods. The as-prepared composites exhibit excellent catalytic and optical properties that originate from the nanostructure as well as the coated porphyrin MOF. We further explored the potential applications of PDA@MOF and PDA@Pt@MOF in nanomedicine and photocatalysis. PMID- 29168376 TI - Tuning the Flexibility of Glycine-Serine Linkers To Allow Rational Design of Multidomain Proteins. AB - Flexible polypeptide linkers composed of glycine and serine are important components of engineered multidomain proteins. We have previously shown that the conformational properties of Gly-Gly-Ser repeat linkers can be quantitatively understood by comparing experimentally determined Forster resonance energy transfer (FRET) efficiencies of ECFP-linker-EYFP proteins to theoretical FRET efficiencies calculated using wormlike chain and Gaussian chain models. Here we extend this analysis to include linkers with different glycine contents. We determined the FRET efficiencies of ECFP-linker-EYFP proteins with linkers ranging in length from 25 to 73 amino acids and with glycine contents of 33.3% (GSSGSS), 16.7% (GSSSSSS), and 0% (SSSSSSS). The FRET efficiency decreased with an increasing linker length and was overall lower for linkers with less glycine. Modeling the linkers using the WLC model revealed that the experimentally observed FRET efficiencies were consistent with persistence lengths of 4.5, 4.8, and 6.2 A for the GSSGSS, GSSSSS, and SSSSSS linkers, respectively. The observed increase in linker stiffness with reduced glycine content is much less pronounced than that predicted by a classical model developed by Flory and co-workers. We discuss possible reasons for this discrepancy as well as implications for using the stiffer linkers to control the effective concentrations of connected domains in engineered multidomain proteins. PMID- 29168378 TI - Molar Range Detection Based on Sideband Differential Absorption Spectroscopy with a Concentrated Reference. AB - Conventional absorption spectroscopy (CAS) with a blank reference has only a slight capacity to detect high concentrations at characteristic wavelengths owing to the corresponding large molar absorption coefficient (epsilon) on the scale of 103 or 104 cm-1 M-1. To monitor concentrated analytes as high as the molar range in a plating bath and on a chemical production line, we propose a new approach using sideband differential absorption spectroscopy (SDAS). SDAS is obtained by subtracting the absorption spectra of the samples, A(lambda,Cx), from that of a reference containing a concentrated standard analyte, A(lambda,Cref>Cx), resulting in concave spectra with peaks at the sideband of conventional spectra with generally low epsilon values on the scale of 100 cm-1 M-1 or less. The negative absorbance changes linearly with the sample concentration at a certain peak wavelength, obeying Lambert-Beer's law. In this work, SDAS was obtained and verified using inorganic and organic substances, such as chromate potassium, rhodamine B, and paracetamol. PMID- 29168379 TI - Autonomously Self-Adhesive Hydrogels as Building Blocks for Additive Manufacturing. AB - We report a simple method of preparing autonomous and rapid self-adhesive hydrogels and their use as building blocks for additive manufacturing of functional tissue scaffolds. Dynamic cross-linking between 2-aminophenylboronic acid-functionalized hyaluronic acid and poly(vinyl alcohol) yields hydrogels that recover their mechanical integrity within 1 min after cutting or shear under both neutral and acidic pH conditions. Incorporation of this hydrogel in an interpenetrating calcium-alginate network results in an interfacially stiffer but still rapidly self-adhesive hydrogel that can be assembled into hollow perfusion channels by simple contact additive manufacturing within minutes. Such channels withstand fluid perfusion while retaining their dimensions and support endothelial cell growth and proliferation, providing a simple and modular route to produce customized cell scaffolds. PMID- 29168380 TI - Quantitative Study of the Oligomerization of Yeast Prion Sup35NM Proteins. AB - The fibrillation of misfolded neurodegenerative disease-related proteins has been extensively studied over the past few decades, but the initial oligomerization has been rarely examined even though some recent evidence indicated that small protein oligomers are more neurotoxic than long protein fibers. It is rather difficult to study the initial oligomerization (nucleation) because most experimental methods, such as the beta-sheet-related fluorescence assay and X-ray diffraction, are unable to detect small structureless protein oligomers. In this study, we have successfully developed a method to link a short thermally sensitive poly(N-isopropylacrylamide) (PNIPAM) chain to a model protein, Sup35NM, at a specific 31st residue site (Sup35NM-31m-PNIPAM) via the efficient thiol-ene Michael addition reaction. The oligomerization was studied by a combination of laser light scattering, the thioflavin T assay, and transmission electron microscopy. We found that the lag phase of Sup35NM was delayed from 12 to >24 h under the physiological condition after the PNIPAM linkage. The oligomerization and fibrillation constants decreased from 5.0 * 10-3 to 1.5 * 10-3 h-1 and from 3.0 * 10-2 to 1.8 * 10-2 MUM-1 h-1, respectively, presumably because of the steric hindrance introduced by the PNIPAM chain. Moreover, after initiating the oligomerization, we found that the oligomer distribution in the first 6 h repeatedly and quantitatively follows the Smoluchowski coagulation model. Our study paves the way for controllably and quantitatively studying the oligomerization kinetics of amyloidogenic proteins. In addition, by investigating the effects of different small molecules on the oligomerization kinetics, we should be able to screen potential drugs to slow the development of neurodegenerative diseases. PMID- 29168381 TI - Cellular Biosensors with Engineered Genetic Circuits. AB - An increasing interest in building novel biological devices with designed cellular functionalities has triggered the search of innovative tools for biocomputation. Utilizing the tools of synthetic biology, numerous genetic circuits have been implemented such as engineered logic operation in analog and digital circuits. Whole cell biosensors are widely used biological devices that employ several biocomputation tools to program cells for desired functions. Up to the present date, a wide range of whole-cell biosensors have been designed and implemented for disease theranostics, biomedical applications, and environmental monitoring. In this review, we investigated the recent developments in biocomputation tools such as analog, digital, and mix circuits, logic gates, switches, and state machines. Additionally, we stated the novel applications of biological devices with computing functionalities for diagnosis and therapy of various diseases such as infections, cancer, or metabolic diseases, as well as the detection of environmental pollutants such as heavy metals or organic toxic compounds. Current whole-cell biosensors are innovative alternatives to classical biosensors; however, there is still a need to advance decision making capabilities by developing novel biocomputing devices. PMID- 29168382 TI - Comparative Proteomic Analysis of Lysine Acetylation in Trypanosomes. AB - Protein acetylation is a post-translational modification regulating diverse cellular processes. By using proteomic approaches, we identified N-terminal and epsilon-lysine acetylated proteins in Trypanosoma cruzi and Trypanosoma brucei, which are protozoan parasites that cause significant human and animal diseases. We detected 288 lysine acetylation sites in 210 proteins of procyclic form, an insect stage of T. brucei, and 380 acetylation sites in 285 proteins in the form of the parasite that replicates in mammalian bloodstream. In T. cruzi insect proliferative form we found 389 epsilon-lysine-acetylated sites in 235 proteins. Notably, we found distinct acetylation profiles according to the developmental stage and species, with only 44 common proteins between T. brucei stages and 18 in common between the two species. While K-ac proteins from T. cruzi are enriched in enzymes involved in oxidation/reduction balance, required for the parasite survival in the host, in T. brucei, most K-ac proteins are enriched in metabolic processes, essential for its adaptation in its hosts. We also identified in both parasites a quite variable N-terminal acetylation sites. Our results suggest that protein acetylation is involved in differential regulation of multiple cellular processes in Trypanosomes, contributing to our understanding of the essential mechanisms for parasite infection and survival.

AB - The C(1)-C(13) fragment of the antimitotic marine macrolide leiodermatolide is prepared in seven steps via hydrogenative and transfer-hydrogenative reductive C C couplings. A hydrogen-mediated reductive coupling of acetylene with a Roche type aldehyde is used to construct C(7)-C(13). A 2-propanol-mediated reductive coupling of allyl acetate with (E)-2-methylbut-2-enal at a low loading of iridium (1 mol %) is used to construct C(1)-C(6), which is converted to an allylsilane using Oestereich's copper-catalyzed allylic substitution of Si-Zn reagents. The union of the C(1)-C(6) and C(7)-C(13) fragments is achieved via stereoselective Sakurai allylation. PMID- 29168384 TI - Tracking Silent Hypersensitivity Reactions to Asparaginase during Leukemia Therapy Using Single-Chip Indirect Plasmonic and Fluorescence Immunosensing. AB - Microbial asparaginase is an essential component of chemotherapy for the treatment of childhood acute lymphoblastic leukemia (cALL). Silent hypersensitivity reactions to this microbial enzyme need to be monitored accurately during treatment to avoid adverse effects of the drug and its silent inactivation. Here, we present a dual-response anti-asparaginase sensor that combines indirect SPR and fluorescence on a single chip to perform ELISA-type immunosensing, and correlate measurements with classical ELISA. Analysis of serum samples from children undergoing cALL therapy revealed a clear correlation between single-chip indirect SPR/fluorescence immunosensing and ELISA used in clinical settings (R2 > 0.9). We also report that the portable SPR/fluorescence system had a better sensitivity than classical ELISA to detect antibodies in clinical samples with low antigenicity. This work demonstrates the reliability of dual sensing for monitoring clinically relevant antibody titers in clinical serum samples. PMID- 29168385 TI - Luminescence Anisotropy and Thermal Effect of Magnetic and Electric Dipole Transitions of Cr3+ Ions in Yb:YAG Transparent Ceramic. AB - In this article, we present an in-depth optical study on luminescence spectral features and the thermal effect of the magnetic dipole (MD) transitions (e.g., the R lines of 2E -> 4A2) and the associated electric dipole transitions (e.g., phonon-induced sidebands of the R lines) of Cr3+ ions in ytterbium-yttrium aluminum garnet polycrystalline transparent ceramic. The doubly split R lines predominately due to the doublet splitting of the 2E level of the Cr3+ ion in an octahedral crystal field are found to show a very large anisotropy in both emission intensity and thermal broadening. The large departure from the intensity equality between them could be interpreted in terms of large difference in coupling strength with phonons for the doubly split states of the 2E level. For the large anisotropy in thermal broadening, very different effective Debye temperatures for the two split states may be responsible for it. Besides the 2E excited state, the higher excited states, for example, 4T1 and 4T2 of the Cr3+ ion, also exhibit a very large inequality in coupling strength with phonons at room temperature. By examining the Stokes phonon sidebands of the MD R lines at low temperatures with the existing ion-phonon coupling theory, we reveal that they indeed carry fundamental information of phonons. For example, their broad background primarily reflects Debye density of states of acoustic phonons. These new results significantly enrich our existing understanding on interesting but challenging luminescence mechanisms of ion-phonon coupling systems. PMID- 29168386 TI - Carbon Nanotube-Doped Adhesive Films for Detecting Crack Propagation on Bonded Joints: A Deeper Understanding of Anomalous Behaviors. AB - A novel nanoreinforced adhesive film has been developed to detect adhesive deformation and crack propagation along the bonding line by means of the electrical response of the material. Adhesive films were doped by spraying an aqueous dispersion of carbon nanotubes (CNTs) over the surface. To determine the sensitivity of bonded joints, single lap shear (SLS) and mode-I fracture energy tests have been carried out while their electrical response has been measured. It has been found that CNT-doped adhesive films are able to detect adhesive deformation and final failure for SLS specimens and crack initiation and propagation along the bonding line for mode-I specimens with a high sensitivity. Sudden increases on electrical resistance are correlated to a rapid growing of the crack length due to instability on crack propagation in a tick-slip case, whereas specimens with a more uniform crack propagation are linked to a steadier increase on electrical resistance, and both of them are properly correlated to the mechanical response. By analyzing more in detail the electrical response and comparing with theoretical approaches, the stick-slip behavior is associated with the presence of porosity and lack of adhesives because of possible manufacturing issues such as adhesive overflowing. These statements are also validated by microstructural analysis. Therefore, the potential and applicability of the proposed adhesive films for evaluating the structural integrity has been demonstrated. PMID- 29168387 TI - Impacts of sodium-glucose co-transporter type 2 inhibitors on central blood pressure. AB - AIMS: To assess the effects of sodium-glucose co-transporter type 2 inhibitors on central blood pressure, an important determinant of cardiovascular events. METHODS: Canagliflozin, Empagliflozin or Luseogliflozin was given for 102 type 2 diabetic patients with hypertension and nephropathy. Central blood pressure was evaluated by radial tonometry. Clinical parameters were followed for 6 months. RESULTS: Three differing sodium-glucose co-transporter type 2 inhibitors similarly reduced brachial and central blood pressures, casual blood sugar, haemoglobin A1c, estimated glomerular filtration rate and albuminuria without significant changes in pulse rate and lipid profiles. Central systolic blood pressure was associated with the decreases in albuminuria by sodium-glucose co transporter type 2 inhibitors. CONCLUSION: Comparable influences of various sodium-glucose co-transporter type 2 inhibitors on central blood pressure suggest class effects. PMID- 29168388 TI - Primer in Genetics and Genomics, Article 6: Basics of Epigenetic Control. AB - The epigenome is a collection of chemical compounds that attach to and overlay the DNA sequence to direct gene expression. Epigenetic marks do not alter DNA sequence but instead allow or silence gene activity and the subsequent production of proteins that guide the growth and development of an organism, direct and maintain cell identity, and allow for the production of primordial germ cells (PGCs; ova and spermatozoa). The three main epigenetic marks are (1) histone modification, (2) DNA methylation, and (3) noncoding RNA, and each works in a different way to regulate gene expression. This article reviews these concepts and discusses their role in normal functions such as X-chromosome inactivation, epigenetic reprogramming during embryonic development and PGC production, and the clinical example of the imprinting disorders Angelman and Prader-Willi syndromes.

PMID- 29168390 TI - The adaptation of everyday practices in the adoption of chronic illness. AB - This article uses social practice theory to examine the role of information seeking in the maintenance of existing lifestyle and illness-related adjustments in the context of chronic illnesses. The research findings are derived from a thematic analysis of 16 semi-structured in-depth interviews with Estonian Parkinson's disease patients. The coding scheme bases on the four practice elements outlined by Schatzki (practical understandings, rules, teleological structures and general understandings) and other categories related to chronic illness self-management skills, bodily movements, daily routines and information seeking practices. The findings reveal that people with chronic illness value maintaining their existing lifestyles as long as possible and the willingness to seek out illness-related information is related to the severity and duration of the disease. These findings suggest that effective illness-related communication that supports self-management should provide patients with possibilities to adjust and switch between practices in a time and a pace that is natural and acceptable to them.

Using her work with the 2011 Penelope Project as a case study, the author identifies core elements of a "Creative Community of Care:" open systems; all activities are accessible; the arts are immersed into the environment of care; projects build on existing assets and rituals; projects evolve over long periods of time; and projects have high cultural value/capital. PMID- 29168392 TI - The Role of Caregivers in Physical Activity for Older Adults With Alzheimer's Disease. AB - This study examined the determinants of physical activity (PA) for older adults with Alzheimer's disease (AD) to learn more about how to promote PA in this population. Caregivers of older adults with AD (N = 99) provided information related to care recipient's PA, as well as addressed sociodemographics and perceptions about their care recipient's PA. Gender of care recipient was a significant predictor of PA (beta = .80, P < .05); men with AD participated in more PA than women with AD. Also, caregiver's outcome expectation for care recipient's PA also predicted more PA (beta = .82, P < .05). Caregiver's perceived benefits of PA (outcome expectation) for their care recipient partially mediated the relationship between self-efficacy for care recipient's PA and the reported levels of PA for the care recipient. This study demonstrated the importance of caregiver perceptions about care recipient's PA. PMID- 29168393 TI - Serum sclerostin in vascular calcification and clinical outcome in chronic kidney disease. AB - Sclerostin, a potent soluble inhibitor of the Wnt signalling pathway, is known to inhibit bone formation by suppressing osteocytes differentiation and function. Patients with chronic kidney disease have high levels of serum sclerostin. Sclerostin has been implicated in the pathogenesis of vascular calcification, which may promote the cardiovascular events of morbidity and mortality in chronic kidney disease patients. However, the role of sclerostin in vascular calcification and clinical prognosis in chronic kidney disease remains elusive. While some studies suggested a positive correlation between serum sclerostin and vascular calcification or clinical outcome, other studies showed no or even negative correlation between them. Small sample size, heterogeneity in enrolled patients, discrepancy in anatomical structure examined and differences in the applied assays may be responsible for the discrepant results. Nonetheless, anti sclerostin antibodies may be a new therapeutic approach to increase bone mass and strength in chronic kidney disease. This review aims to have a better understanding of the relationship of serum sclerostin with vascular calcification and clinical outcome in chronic kidney disease patients, and propose the application of anti-sclerostin therapy in chronic kidney disease. PMID- 29168394 TI - Documentation of Child Maltreatment in Electronic Health Records. AB - International Classification of Diseases codes for child maltreatment can aid surveillance and research, but the extent to which they are used is not well established. We documented prevalence of the use of maltreatment-related codes, examined demographic characteristics of youth assigned these codes, and compared results with previous studies. Data were extracted from electronic health records of 0- to 21-year-olds assigned 1 of 15 maltreatment-related International Classification of Diseases, Ninth Revision, codes who had encounters in a large medical system over a 4-year period. Only 0.02% of approximately 2.5 million youth had a maltreatment-related code, replicating other studies. Results provide a dramatic contrast to much higher rates based on self-report or informant-report and referrals to Child Protective Services. Lack of documentation of maltreatment in electronic health records can lead to missed chances at early intervention, inadequate coordination of health care, insufficient allocation of resources to addressing problems related to maltreatment, and flawed public health data.

PMID- 29168396 TI - Intra-rater repeatability of gait parameters in healthy adults during self-paced treadmill-based virtual reality walking. AB - Self-paced treadmill walking is becoming increasingly popular for the gait assessment and re-education, in both research and clinical settings. Its day-to day repeatability is yet to be established. This study scrutinised the test retest repeatability of key gait parameters, obtained from the Gait Real-time Analysis Interactive Lab (GRAIL) system. Twenty-three male able-bodied adults (age: 34.56 +/- 5.12 years) completed two separate gait assessments on the GRAIL system, separated by 5 +/- 3 days. Key gait kinematic, kinetic, and spatial temporal parameters were analysed. The Intraclass-Correlation Coefficients (ICC), Standard Error Measurement (SEM), Minimum Detectable Change (MDC), and the 95% limits of agreements were calculated to evaluate the repeatability of these gait parameters. Day-to-day agreements were excellent (ICCs > 0.87) for spatial temporal parameters with low MDC and SEM values, <0.153 and <0.055, respectively. The repeatability was higher for joint kinetic than kinematic parameters, as reflected in small values of SEM (<0.13 Nm/kg and <3.4 degrees ) and MDC (<0.335 Nm/kg and <9.44 degrees ). The obtained values of all parameters fell within the 95% limits of agreement. Our findings demonstrate the repeatability of the GRAIL system available in our laboratory. The SEM and MDC values can be used to assist researchers and clinicians to distinguish 'real' changes in gait performance over time. PMID- 29168399 TI - Vacuolar ATPase as a possible therapeutic target in human acute myeloid leukemia. AB - INTRODUCTION: V-ATPase is a proton pump expressed both in the membrane of intracellular organelles (e.g. endosomes, lysosomes, Golgi structures) and the plasma membrane. It is an important regulator of organellar functions, intracellular molecular trafficking, intercellular communication and intracellular signaling. It is therefore considered as a possible therapeutic target in the treatment of human malignancies. Areas covered: Relevant publications were identified through literature searches in the PubMed database. We searched for original articles and reviews describing the possible importance of V-ATPase for leukemogenesis and chemosensitivity in human myeloid cells, especially acute myeloid leukemia (AML) cells. Expert commentary: The expression of V-ATPase in the primary human AML cells varies between patients, and high levels are associated with high constitutive release of a wide range of soluble mediators. Several of the molecules included in the V-ATPase interactome may also be important in leukemogenesis and/or development of chemoresistance in human AML. Therapeutic targeting of V-ATPase should therefore be regarded as a possible therapeutic strategy in human AML, but the efficiency of such targeting will probably differ between patients. The possibility of toxicity, especially hematological toxicity and immunosuppression, also has to be clarified. PMID- 29168398 TI - Paraoxonase, arylesterase and lactonase activities of paraoxonase-1 (PON1) in obese and severely obese women. AB - Obesity is independently associated with disturbances in lipid and lipoprotein metabolism, oxidative stress, and is a well-established independent risk factor for cardiovascular diseases (CVD). Human paraoxonase 1 (PON1) is a pleotropic high-density lipoprotein (HDL)-associated enzyme with antioxidant and anti inflammatory proprieties that have been suggested to contribute to the athero protective function of the lipoprotein. The aim of this study was to investigate whether obesity is associated with PON1 activity and whether this association is influenced by oxidative stress, inflammation and HDL cholesterol (HDL-C) concentration. The promiscuous activities, arylesterase and paraoxonase, and the putative physiological activity, lactonase, of PON1 were assessed in the serum of 214 obese and severely obese, 101 overweight and 129 normal-weight women. Levels of high-sensitivity C-reactive protein (hs-CRP), hydroperoxides (by-products of lipid oxidative damage) and lipid profiles were also evaluated. Arylesterase activity was the only activity that significantly differed across the groups (ANOVA, p < .01), with the greatest decrease observed in individuals with body mass index (BMI) > 40 kg/m2 compared to controls (p < .001). This activity was also inversely, although weakly (r = -0.160, p < .001) correlated with the BMI, and the association was independent of age and levels of oxidative stress and inflammation, but not of HDL-C concentration. In conclusion, our results suggest that the apparent obesity-associated decrement of PON1 activity might simply reflect the decrease in concentration of its plasmatic carrier. PMID- 29168400 TI - Cardiovascular disease patients have increased risk for comorbidity: A cross sectional study in the Netherlands. AB - BACKGROUND: Comorbidity is a cause of increased mortality, decreased quality of life and increased use of healthcare services. It is important particularly for physicians and other healthcare providers in primary care settings to evaluate these patients properly. Cardiovascular diseases (CVD) are the most common cause of death from non-communicable diseases worldwide and are characterized by a high level of comorbidities. OBJECTIVES: To address the distribution of CVDs and comorbidities across sociodemographic groups and associations between CVDs and comorbidities. METHODS: A cross-sectional study was conducted using data of 67 786 patients. Data were collected by the Registration Network Family Practices (RegistratieNet Huisartspraktijken, RNH). Comorbidities were analysed using chi square and logistic regression analyses. RESULTS: At the time of study, 26.5% of the patients had at least one CVD and 10.5% of patients had two or more CVD diagnoses. The strongest association within cardiovascular diseases were between health failure and arrhythmias (OR: 9.20; 95%CI: 7.78-10.89). Coronary artery disease and hypertension had strong relationship with diabetes (OR: 2.22; 95%CI: 2.02-2.45, OR: 2.22; 95%CI: 2.02-2.45 respectively) and lipid metabolism disorders (OR: 2.04; 95%CI: 1.87-2.23, OR: 2.04; 95%CI: 1.87-2.23, respectively). The strongest associations for cerebrovascular diseases were with epilepsy (OR: 4.09; 95%CI: 3.29-5.10) and arrhythmias (OR: 2.23; 95%CI: 1.99-2.50). CONCLUSION: One out of every four patients suffered from at least one CVD. Having one CVD increased the risk of another, co-occurring CVD and a higher number of other chronic diseases. PMID- 29168401 TI - The clinical benefit of hyperthermia in pancreatic cancer: a systematic review. AB - OBJECTIVE: In pancreatic cancer, which is therapy resistant due to its hypoxic microenvironment, hyperthermia may enhance the effect of radio(chemo)therapy. The aim of this systematic review is to investigate the validity of the hypothesis that hyperthermia added to radiotherapy and/or chemotherapy improves treatment outcome for pancreatic cancer patients. METHODS AND MATERIALS: We searched MEDLINE and Embase, supplemented by handsearching, for clinical studies involving hyperthermia in pancreatic cancer patients. The quality of studies was evaluated using the Oxford Centre for Evidence-Based Medicine levels of evidence. Primary outcome was treatment efficacy; we calculated overall response rate and the weighted estimate of the population median overall survival (mp) and compared these between hyperthermia and control cohorts. RESULTS: Overall, 14 studies were included, with 395 patients with locally advanced and/or metastatic pancreatic cancer of whom 248 received hyperthermia. Patients were treated with regional (n = 189), intraoperative (n = 39) or whole-body hyperthermia (n = 20), combined with chemotherapy, radiotherapy or both. Quality of the studies was low, with level of evidence 3 (five studies) and 4. The six studies including a control group showed a longer mp in the hyperthermia groups than in the control groups (11.7 vs. 5.6 months). Overall response rate, reported in three studies with a control group, was also better for the hyperthermia groups (43.9% vs. 35.3%). CONCLUSIONS: Hyperthermia, when added to chemotherapy and/or radiotherapy, may positively affect treatment outcome for patients with pancreatic cancer. However, the quality of the reviewed studies was limited and future randomised controlled trials are needed to establish efficacy.

AB - BACKGROUND: Radio-frequency ablation has been an important physical method for tumor hyperthermia therapy. The conventional rigid electrode boards are often uncomfortable and inconvenient for performing surgery on irregular tumors, especially for those tumors near the joints, such as ankles, knee-joints or other facets like finger joints. MATERIAL AND METHODS: We proposed and demonstrated a highly conformable tumor ablation strategy through introducing liquid metal bath as conformable soft electrodes. Different heights of liquid metal bath electrodes were adopted to perform radio-frequency ablation on targeted tissues. Temperature and ablation area were measured to compare the ablation effect with plate metal electrodes. RESULTS: The recorded temperature around the ablation electrode was almost twice as high as that with the plate electrode and the effective ablated area was 2-3 fold larger in all the mimicking situations of bone tumors, span shaped or round-shaped tumors. Another unique feature of the liquid metal electrode therapy is that the incidence of heat injury was reduced, which is a severe accident that can occur during the treatment of irregular tumors with plate metal boards. CONCLUSIONS: The present method suggests a new way of using soft liquid metal bath electrodes for targeted minimally invasive tumor ablation in future clinical practice.

PMID- 29168404 TI - Impact of a chronic pain management pathway on opioid administration and prescribing in an Emergency Department. AB - CONTEXT: Prescription opioid abuse and misuse is a significant public health crisis. In 2012, an opioid prescribing pathway for patients with chronic pain presenting to the Emergency Department (ED) was implemented. The objective of this study is to determine the impact of the pathway for administration of opioids in the ED as well as the prescribing of opioids for home use after discharge. METHODS: Retrospective pre- and post-intervention time series study of consecutive patients presenting to the ED with acute and chronic pain complaints before and after implementation of the pathway. For the purposes of this study, we included patients with chronic abdominal or back pain - defined as pain present for greater than three months - and acute pain as acute long bone fracture. RESULTS: Before pathway implementation, there was no statistically significant difference in the mean morphine equivalent (MEQ) dose administered for chronic or acute pain patients. After pathway implementation, there was a decrease in IV/IM morphine administered to patients with chronic pain (p = .0200) but not to patients with acute pain (p = .0820). Overall, MEQs administered did not change in either group. In the acute pain group, no significant differences were found in the number of patients who received opioid prescriptions upon discharge (p = .7749). However, in the chronic pain group, the number of patients who received opioid prescriptions upon discharge decreased with statistical significance (p = .0017). CONCLUSIONS: After the implementation of a chronic pain management pathway in an ED, there is a decrease noted in opioids administered to patients with chronic pain both in the ED and prescriptions on discharge. In patients presenting with acute pain, there was no change in administration or prescription of opioids. PMID- 29168405 TI - Acrylamide attenuated immune tissues' function via induction of apoptosis and oxidative stress: Protection by l-carnitine. AB - Acrylamide (ACR), with high prevalence in starchy food, has been associated with the development of several organ toxicities such as immunotoxicity. This study aimed to demonstrate the role of oxidative stress and apoptosis as the mechanisms involved in ACR-induced immunotoxicity in mice. Mice were randomly assigned to six groups and treated as follows: control (normal saline), cyclophosphamide (200 mg kg-1), ACR groups (12.5, 25 and 50mg kg-1, orally), and l-carnitine (l-CAR; 100 mg kg-1) + ACR (50 mg kg-1). After 30 days of exposure, mice were killed and immunotoxic response was evaluated via immune blood cells count and body/organ weights. Oxidative stress parameters and pathological examination were done in thymus and spleen. Also, the apoptosis was evaluated via flow cytometric by annexin V/FITC kit in the splenocytes. Our results indicated that ACR could induce immunotoxicity characterized by reduction in immune blood cells, body/organ weights, and pathological changes in spleen. The assessment of oxidative stress markers revealed increase in lipid peroxidation, protein carbonyl content, and depletion of glutathione level. Also, increased apoptosis was observed in splenocytes after ACR administration compared to the control group. These alterations were markedly normalized by coadministration of l-CAR (as a potent antioxidant). Taken together, the results of this study showed the potential of ACR to induce immunotoxicity through provoking oxidative stress and inducing apoptosis and the protective effect of l-CAR to attenuate this toxicity. These findings will help in elucidating the toxicity mechanism induced by ACR. PMID- 29168407 TI - Mortality and recurrence rates among systemically untreated high risk breast cancer patients included in the DBCG 77 trials. AB - BACKGROUND: Following loco-regional treatment for early breast cancer accurate prognostication is essential for communicating benefits of systemic treatment. The aim of this study was to determine time to recurrence and long-term mortality rates in high risk patients according to patient characteristics and subtypes as assigned by immunohistochemistry panels. PATIENTS AND METHODS: In November 1977 through January 1983, 2862 patients with tumors larger than 5 cm or positive axillary nodes were included in the DBCG 77 trials. Archival tumor tissue from patients randomly assigned to no systemic treatment was analyzed for ER, PR, Ki67, EGFR and HER2. Intrinsic subtypes were defined as follows: Luminal A, ER or PR >0%, HER2-negative, PR >10% and Ki67 < 14%; Luminal B, ER or PR >0%, (PR <=10% or HER2-positive or Ki67 >= 14%); HER2E, ER 0%, PR 0%, HER2 positive; Core basal, ER 0%, PR 0%, HER2 negative and EGFR positive. Multivariate categorical and fractional polynomials (MFP) models were used to construct prognostic subsets by clinicopathologic characteristics. RESULTS: In a multivariate model, mortality rate was significantly associated with age, tumor size, nodal status, invasion, histological type and grade, as well as subtype classification. CONCLUSIONS: With 35 years of follow-up, in this population of high-risk patients with no systemic therapy, no subgroup based on a composite prognostic score and/or molecular subtypes could be identified without excess mortality as compared to the background population. PMID- 29168408 TI - Main messages for primary care from the 2016 European Guidelines on cardiovascular disease prevention in clinical practice. AB - In 2016, a new version of the European Guidelines on Cardiovascular Prevention was released, representing a partnership between the European Association for Cardiovascular Prevention and Rehabilitation of the European Society of Cardiology (ESC) and nine European societies, including Wonca-Europe. The ESC guidelines underscore the importance of a lifetime approach to cardiovascular (CV) risk since both CV risk and prevention are dynamic and continuous as patients' age and/or accumulate co-morbidities. Healthy people of all ages should be encouraged to adopt a healthy lifestyle, as well as improved lifestyle and reduced risk factor levels are paramount in patients at increased risk of developing cardiovascular disease (CVD) and in those with established CVD. Healthcare professionals, and especially general practitioners, play an important role in helping patients achieve this and should set a personal example of healthy lifestyle behaviour. The ESC guidelines are based on 'to do' and 'not to do' messages. Of note, what remains uncertain is stated at the end of each dedicated chapter, confirming that guidelines are not absolute rules, and should be interpreted in the light of the healthcare worker's knowledge and experience, patient preferences and the local social, cultural and economic situation. PMID- 29168409 TI - How do Swiss general practitioners agree with and report adhering to a top-five list of unnecessary tests and treatments? Results of a cross-sectional survey. AB - BACKGROUND: In 2014, the 'Smarter Medicine' campaign released a top five list of unnecessary tests and treatments in Swiss primary care, such as imaging for acute low-back pain and long-term prescribing of proton pump inhibitors. OBJECTIVES: Measure general practitioners' (GPs) agreement with the recommendations and self reported adherence. METHODS: Cross-sectional, online survey of GPs in the 'Swiss primary care active monitoring' (SPAM) network, which assessed awareness of 'Smarter Medicine' and views on each recommendation. Questions included whether the clinical situation is common, whether the recommendation is followed, whether GPs agree with the recommendation and reasons why the recommendation would not be followed. RESULTS: One-hundred-and-sixty-seven of 277 GPs from the SPAM network participated (60%), of which 104 (62%) knew of 'Smarter Medicine', including 79% in German areas, 49% in French areas and 38% in Italian areas (P < 0.001). Agreement with the five recommendations was high, with scores around nine out of 10. The proportion saying they typically follow each recommendation was 68 to 74%, except not continuing long-term PPI prescriptions without attempting dose reduction, with only 34%. Common reasons for not following the recommendations were patient or other provider requests and situations that might suggest the need for more aggressive care. CONCLUSION: Two years after the launch of the campaign, awareness and acceptance of 'Smarter Medicine' appear to be high among Swiss GPs. By self-report, the recommendations are adhered to by most of the respondents but there may be room for improvement, especially for long-term PPI prescriptions.

PMID- 29168406 TI - TGFbeta as a therapeutic target in cystic fibrosis. AB - INTRODUCTION: Cystic fibrosis (CF) is a genetic disease characterized by progressive lung disease. Most CF therapies focus on treating secondary pulmonary complications rather than addressing the underlying processes inducing airway remodeling and ineffective response to infection. Transforming growth factor beta (TGFbeta) is a cytokine involved in fibrosis, inflammation, and injury response as well as a genetic modifier and biomarker of CF lung disease. Targeting the TGFbeta pathway has been pursued in other diseases, but the mechanism of TGFbeta effects in CF is less well understood. Areas covered: In this review, we discuss CF lung disease pathogenesis with a focus on potential links to TGFbeta. TGFbeta signaling in lung health and disease is reviewed. Recent studies investigating TGFbeta's impact in CF airway epithelial cells are highlighted. Finally, an overview of potential therapies to target TGFbeta signaling relevant to CF are addressed. Expert opinion: The broad impact of TGFbeta signaling on numerous cellular processes in homeostasis and disease is both a strength and a challenge to developing TGFbeta dependent therapeutics in CF. We discuss the challenges inherent in developing TGFbeta-targeted therapy, identifying appropriate patient populations, and questions regarding the timing of treatment. Future directions for research into TGFbeta focused therapeutics are discussed. PMID- 29168411 TI - Primary healthcare policy implementation in the Eastern Mediterranean region: Experiences of six countries. AB - BACKGROUND: Primary healthcare (PHC) is essential for equitable access and cost effective healthcare. This makes PHC a key factor in the global strategy for universal health coverage (UHC). Implementing PHC requires an understanding of the health system under prevailing circumstances, but for most countries, no data are available. OBJECTIVES: This paper describes and analyses the health systems of Bahrain, Egypt, Lebanon, Qatar, Sudan and the United Arab Emirates, in relation to PHC. METHODS: Data were collected during a workshop at the WONCA East Mediterranean Regional Conference in 2017. Academic family physicians (FP) presented their country, using the WONCA framework of 11 PowerPoint slides with queries of the country demographics, main health challenges, and the position of PHC in the health system. RESULTS: All six countries have improved the health of their populations, but currently face challenges of non-communicable diseases, aging populations and increasing costs. Main concerns were a lack of trained FPs in community settings, underuse of prevention and of equitable access to care. Countries differed in the extent to which this had resulted in coherent policy. CONCLUSION: Priorities were (i) advocacy for community-based PHC to policymakers, including the importance of coordination of healthcare at the community level, and UHC to respond to the needs of populations; (ii) collaboration with universities to include PHC as a core component of every medical curriculum; (iii) collaboration with communities to improve public understanding of PHC; (iv) engagement with the private sector to focus on PHC and UHC. PMID- 29168412 TI - Persistent symptoms in patients with Crohn's disease in remission: An exploratory study on the role of diet. AB - OBJECTIVES: Patients with Crohn's disease (CD) often report food hypersensitivities with gastrointestinal (GI) symptoms despite being in clinical remission. We aimed to identify the most frequent symptoms and dietary triggers in such patients, and also explored whether a strict elimination diet may reduce their GI symptoms. METHODS: We assessed GI symptoms and dietary triggers in 16 patients with CD in clinical remission. Of these, 12 patients subsequently participated in a dietary intervention trial: two weeks on a habitual diet including wheat and dairy products followed by two weeks of a strict elimination diet. The severity of seven symptoms (overall symptoms, abdominal pain, bloating, abnormal feces, wind, fatigue, and musculoskeletal pain) was measured by using visual analog scales throughout the four weeks intervention period. MAIN RESULTS: The most common symptoms were abdominal pain, wind, bloating, odorous wind/feces, and diarrhea. Dairy and wheat products were reported as the most frequent dietary symptom triggers. All symptoms improved (p < .05) during the elimination diet period, especially in patients with small intestinal affection. CONCLUSION: Our exploratory study suggests that dietary interventions such as an elimination diet may reduce GI symptoms in patients with CD in remission.

AB - Predicting the phenotypic impact of mutations is a central challenge in population and functional genetics. The analysis of DNA and amino acid sequence variation in an evolutionary context is a robust approach to infer the fitness effects of genetic variants. In this review, we discuss the most popular methods based on this approach, covering both theoretical and practical aspects, and introduce compelling software for predicting the functional effects of mutations, and to highlight functionally relevant nucleotide or amino acid candidate positions. Furthermore, we provide some examples of their application to Drosophila genes affecting significant aspects of the development, physiology and function of the nervous system. PMID- 29168414 TI - Knowledge, competencies and attitudes regarding external post-mortem physical examination: A survey among German post-graduate trainees in general practice. AB - BACKGROUND: The external post-mortem examination (EPME) is an important medical, legal and socio-economic task with far-reaching relevance; however, due to discrepancies between findings from EPMEs and actual cause of death, improvements in accuracy and quality are needed. OBJECTIVES: To investigate knowledge, competencies and attitudes regarding EPME in general practitioner (GP) post graduate trainees. METHODS: Before four post-graduate training courses on the EPME for general practitioner trainees, organized in 2014 in the German federal state of Baden-Wuerttemberg, a questionnaire on the EPME was distributed by the lecturer, completed by the GP post-graduate trainees and returned to the lecturer. The questionnaire consisted of 19 items related to three main categories: knowledge, competencies and attitudes. RESULTS: Out of 380 GP post graduate trainees, 128 completed and returned the questionnaire (response rate 33.7%). Less than 18% felt adequately confident in identifying a natural cause of death and less than 5% felt adequately confident in identifying an unnatural cause of death. Only 33% consistently fully uncover the corpse for the EPME. CONCLUSION: We found an important uncertainty in GP post-graduate trainees regarding their EPME knowledge and competencies.

PMID- 29168418 TI - Telemedicine in Diabetic Foot Care: A Systematic Literature Review of Interventions and Meta-analysis of Controlled Trials. AB - The care of individuals with diabetic foot ulcers is costly and requires multiple hospital visits. Inadequate care leads to serious complications and a high risk of lower extremity amputation. In this review, we aimed at evaluating whether telemedicine can be effective in diabetic foot patient care. We searched Medline through Embase and PubMed and Cochrane Central Register of Controlled Trials (CENTRAL) for relevant studies, published up to April 2017. The studies were summarized and discussed in a narrative method and a meta-analysis of 2 controlled trials was conducted using the fixed-effects model. The main outcomes, assessed in the retrieved studies were the healing rate and satisfaction of patients and health care personnel. Most of the studies showed that implementing telemonitoring programs increased the rate of complete ulcer healing, while the patients were highly satisfied. Two trials providing data on 213 patients on telemedicine and 301 patients on usual care were included for meta-analysis. Subjects in telemedicine, as well as control groups had statistically similar healing time (43 vs 45 days; P = .83), healing time ratio adjusted for age (1 vs 1.4; P = .1), unhealed ulcers or loss to follow-up (3 of 20 vs 7 of 120; P = .13), and amputations (12 of 193 vs 14 of 182; P = .59). Subjects in the telemedicine group experienced a significantly higher mortality rate (8 of 193 vs 1 of 181; P = .0001) due to unexplained factors. No adverse events were attributed to using the telemedicine technology. The odds of complete ulcer healing were statistically similar between the telemedicine group and controls (odds ratio = 0.86; 95% CI = 0.57-1.33; P = .53). Telemedicine care is promising for the management of diabetic foot patients as the results were comparable with usual care. However, further large-scale studies need to be undertaken before it can be implemented widely. PMID- 29168417 TI - A DNA segment encoding the anticodon stem/loop of tRNA determines the specific recombination of integrative-conjugative elements in Acidithiobacillus species. AB - Horizontal gene transfer is crucial for the adaptation of microorganisms to environmental cues. The acidophilic, bioleaching bacterium Acidithiobacillus ferrooxidans encodes an integrative-conjugative genetic element (ICEAfe1) inserted in the gene encoding a tRNAAla. This genetic element is actively excised from the chromosome upon induction of DNA damage. A similar genetic element (ICEAcaTY.2) is also found in an equivalent position in the genome of Acidithiobacillus caldus. The local genomic context of both mobile genetic elements is highly syntenous and the cognate integrases are well conserved. By means of site directed mutagenesis, target site deletions and in vivo integrations assays in the heterologous model Escherichia coli, we assessed the target sequence requirements for site-specific recombination to be catalyzed by these integrases. We determined that each enzyme recognizes a specific small DNA segment encoding the anticodon stem/loop of the tRNA as target site and that specific positions in these regions are well conserved in the target attB sites of orthologous integrases. Also, we demonstrate that the local genetic context of the target sequence is not relevant for the integration to take place. These findings shed new light on the mechanism of site-specific integration of integrative-conjugative elements in members of Acidithiobacillus genus. PMID- 29168419 TI - Truncated forms of U2 snRNA (U2-tfs) are shunted toward a novel uridylylation pathway that differs from the degradation pathway for U1-tfs. AB - During the biogenesis of U1 small nuclear ribonucleoprotein, a small population of U1 snRNA molecules acquires an extra methylation at the first transcribed nucleotide and a nucleolytic cleavage to remove the 3' structured region including the Sm protein-binding site and stem-loop 4. These modifications occur before hypermethylation of the monomethylated 5' cap, whereby producing truncated forms of U1 snRNA (U1-tfs) that are diverted from the normal pathway to a processing body-associated degradation pathway. Here, we demonstrate that a small population of U2 snRNA molecules receives post-transcriptional modifications similar to those of U1 to yield U2-tfs. Like U1-tfs, U2-tfs molecules were produced from transcripts of the U2 snRNA gene having all cis-elements or lacking the 3' box. Unlike U1-tfs, however, a portion of U2-tfs received additional uridylylation of up to 5 nucleotides in length at position 87 (designated as U2 tfs-polyU) and formed an Sm protein-binding site-like structure that was stabilized by the small nuclear ribonucleoprotein SmB/B' probably as a part of heptameric Sm core complex that associates to the RNA. Both U2-tfs and U2-tfs polyU were degraded by a nuclease distinct from the canonical Dis3L2 by a process catalyzed by terminal uridylyltransferase 7. Collectively, our data suggest that U2 snRNA biogenesis is regulated, at least in part, by a novel degradation pathway to ensure that defective U2 molecules are not incorporated into the spliceosome.

PMID- 29168420 TI - Vulnerabilities in sequencing and task switching in healthy youth offspring of parents with mood disorders. AB - INTRODUCTION: Visuospatial processing and task switching are impaired in individuals with mood disorders. It is unknown whether early deficits are present before mood symptom on set or are related to risk for a specific type of mood disorder. To investigate, we compared visual attention and task switching during sequencing among never-disordered youth with parental family histories of bipolar (BD) and major depressive disorders (MDD) and healthy controls (HC) with no personal or family history of psychopathology. METHOD: 8-17-year-old youth of parents with BD (n = 31, "BD-risk"), youth of parents with MDD (n = 49, "MDD risk"), and demographically similar HC (n = 31, "HC") were examined using the Delis-Kaplan Executive Functioning System Trail Making Test. Seed-based resting state functional connectivity (RSFC) was collected from a subset of 88 participants (25 BD-risk, 37 MDD-risk, 26 HC) to investigate group differences in RSFC related to visuospatial processing. RESULTS: BD-risk and MDD-risk offspring had impaired sequencing and task switching, demonstrated by reduced scores on visual scanning, F(2, 108) = 4.12, p = .02, number sequencing, F(2, 88) = 4.75, p = .01, letter sequencing, F(2, 108) = 4.24, p = .02, and number-letter sequencing, F(2, 108) = 4.66, p = .01, compared to scores in HC. RSFC between the posterior cingulate (PCC) and clusters in the subcallosal cortex, amygdala, and hippocampus significantly differed among HC, BD-risk, and MDD-risk groups. PCC subcallosal/limbic RSFC was positively coupled in the MDD-risk and BD-risk groups and negatively coupled in HCs. CONCLUSIONS: Youth at familial risk for mood disorders demonstrate visuospatial deficits early in the processing stream. Improved methods for identifying at-risk children with the earliest possible neurocognitive impairments may inform remediation strategies that could prevent mood disorders. PMID- 29168422 TI - Evaluation of Youth Enjoyment Toward Physical Activity and Sedentary Behavior. AB - PURPOSE: The consensus is that physical activity (PA) and sedentary behavior (SB) are independent behaviors, but past findings suggest that they may be influenced by common underlying factors. To clarify this issue, we examined associations between enjoyment of PA and participation in both PA and SB in a large sample of 4th- to 12th-grade US youth. METHODS: A total of 18,930 students from 187 schools completed the youth activity profile, a self-report 15-item survey that assesses time spent in PA and SB in school and home settings. Two additional items captured enjoyment of PA and physical education. Two-way (gender * enjoyment and grade * enjoyment) mixed analysis of variances were conducted. RESULTS: Pearson correlation results revealed a positive relationship between enjoyment and PA (r = .38, P < .05) and an inverse correlation between enjoyment and SB (r = -.23, P < .05). Statistically significant main effects of enjoyment were found in the 2 way analysis of variance for both PA and SB. The simple main effect from analysis of variance indicated students with high enjoyment of PA reported higher levels of PA and lower levels of SB compared with students reporting moderate or low levels of enjoyment. CONCLUSION: The results provide new insights related to the relevance of enjoyment as a common underlying variable influencing both PA and SB across gender and grade levels. PMID- 29168423 TI - Vitamin D levels in children and adolescents with obsessive compulsive disorder. AB - BACKGROUND: Recent studies showed that vitamin D deficiency may lead to dysfunctional changes in the brain and may be associated with neuropsychiatric diseases. AIMS: The present study aims to investigate vitamin D, calcium, phosphorus and alkaline phosphatase levels in children and adolescents diagnosed with obsessive-compulsive disorder (OCD) and compared them to healthy controls. Additionally, the correlation of OCD symptom severity with serum vitamin D level will be analyzed. METHODS: A semi-structured interview form (K-SADS-PL) was used to diagnose OCD and other comorbidities in accordance with DSM-IV criteria. In addition, all participants were assessed with clinical interviews based on DSM-5 OCD diagnostic criteria. Children's Yale Brown Obsession Compulsion Scale (CY BOCS) and Children's Depression Inventory were used in the clinical evaluation. RESULTS: Vitamin D levels were lower in patients diagnosed with OCD (15.88 +/- 6.96 ng/mL) when compared to healthy controls (18.21 +/- 13.24 ng/mL), but the difference was not statistically significant (p = .234). Serum calcium, serum phosphate and serum alkaline phosphatase levels were not different between the groups. A negative correlation was found between serum 25OH-D3 levels and obsession scale scores in CY-BOCS. CONCLUSIONS: To our knowledge this is the first study that evaluated vitamin D levels in OCD patients without comorbidity. The vitamin D levels of newly diagnosed OCD cases were lower but not statistically different than healthy controls. Furthermore, the study does also not support the presence of a significant association between serum vitamin D levels and OCD.

PMID- 29168424 TI - A prognostic scoring system using inflammatory response biomarkers in oral cavity squamous cell carcinoma patients who underwent surgery-based treatment. AB - BACKGROUND: The aim of this study was to evaluate the effectiveness of a scoring system based on the lymphocyte-to-monocyte ratio, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio for predicting disease-specific survival of oral cancer patients treated by surgery. METHODS: From January 2007 to December 2016, we retrospectively analyzed data from 69 oral cancer patients who received surgery. RESULTS: Lymphocyte-to-monocyte ratio was significantly associated with T classification, N classification, and pathologic stage. Neutrophil-to lymphocyte ratio was significantly associated with T classification and pathologic stage. Platelet-to-lymphocyte ratio was significantly associated with N classification and pathologic stage. In multivariate analysis, only a higher score on this scoring system was significantly associated with poorer disease specific survival. CONCLUSIONS: We found that the prognostic score system based on these three values was significantly associated with disease-specific survival of oral cancer patients who received surgery, indicating that the prognostic scoring system was effective in indirectly predicting systemic inflammatory response. PMID- 29168426 TI - Interleukin-18 and testosterone levels in men with metabolic syndrome. AB - OBJECTIVE: Interleukin 18 (IL-18) is an adipokine associated with obesity. Data about the relationship of IL-18 to the metabolic syndrome (MS) are still scarce. Low testosterone (T) levels are common in men with MS, but we did not find data about the levels of IL-18 in men with low T. The aim of this study was to determine the levels of IL-18 in men with MS with or without low T. PATIENTS AND METHODS: A total of 251 men were included in the study. Of them 218 had MS (IDF 2005) and they were divided according to their morning total testosterone (TT) level (cutoff 10.4 nmol/l) into two groups: MS-low T (N = 84) and MS-normal T (N = 134). The control group consisted of 33 men without MS and low T. IL-18 was determined in serum using enzyme-linked immunosorbent assay. A small group of eight men with MS and low T levels received testosterone therapy for three months and physical and laboratory parameters were monitored at the end of that period. RESULTS: MS men were at mean age (+/-SD) = 53.77 +/- 9.59 years; body mass index (BMI) = 34.0 +/- 6.3 kg/m2; and TT = 12.59 +/- 5.66 nmol/l. The control group was at age = 52.12 +/- 5.2 years (NS); BMI = 25.6 +/- 2.4 kg/m2 (p < .001); and TT = 17.8 +/- 5.68 nmol/l (p < .001), respectively. The levels of IL-18 were higher in the MS group - 345 pg/ml compared to the control one - 264 pg/ml (p < .01). There was no significant difference between MS-low T (330.6 pg/ml) and MS-normal T (350.2 pg/ml) subgroups. The MS-normal T differed more significantly from the control group (p < .001). Significant correlation of testosterone with IL-18 levels was not found. IL-18 correlated with parameters of obesity, lipids, fasting blood sugar (p < .05) and the number of criteria for MS (p < .001). Three months on T treatment showed improvement in obesity parameters and only in one patient IL-18 had clear reduction while the rest showed no change. CONCLUSIONS: In this study, higher IL-18 levels were found in the presence of MS compared to healthy men, but they did not differ between men having MS with or without LOH.

AB - INTRODUCTION: Neoadjuvant endocrine treatment (NET) is a low-toxicity approach to achieve operability in locally advanced breast cancer, and to facilitate breast conservation in early breast cancer, particular in patients with highly estrogen receptor (ER) positive and HER2-negative disease. Here, we report the results obtained by neoadjuvant letrozole in patients with early breast cancer in a phase II design. MATERIAL AND METHODS: A total of 119 postmenopausal women with ER positive, HER2-negative operable breast cancer were assigned to four months of neoadjuvant letrozole before definitive surgery. Sentinel node or diagnostic fine needle aspiration cytology procedure was performed prior to treatment and the women were assessed prior, at two months, and before surgery with clinical examination, mammography and ultrasonography. Surgical specimens were examined for pathological response. Primary outcome was pathological and clinical response. RESULTS: The per protocol population consisted of 112 patients. Clinical response was evaluated in 109 patients and pathological response in 108. Overall a mean decrease in tumor size was 15% (p <= .0001). One patient had complete pathological response and 55% of patients had partial pathological response. ER at 100%, ductal subtype, tumor size below 2 cm and lymph node negative status was significantly associated with a better response to NET and malignancy grade 3 with a poorer response to NET. One patient progressed during treatment and received neoadjuvant chemotherapy. Eight patients received adjuvant chemotherapy due to lack of response. CONCLUSION: Neoadjuvant aromatase inhibitor therapy is an acceptable strategy in selected postmenopausal patients with ER rich and HER2-negative early breast cancer with ductal histology and should be considered when chemotherapy either isn't indicated or feasible. PMID- 29168428 TI - Standardized assessment of tumor-infiltrating lymphocytes in breast cancer: an evaluation of inter-observer agreement between pathologists. AB - INTRODUCTION: In breast cancer, there is a growing body of evidence that tumor infiltrating lymphocytes (TILs) may have clinical utility and may be able to direct clinical decisions for subgroups of patients. Clinical utility is, however, not sufficient for warranting the implementation of a new biomarker in the routine practice, and evaluation of the analytical validity is needed, including testing the reproducibility of decentralized assessment of TILs. The aim of this study was to evaluate the inter-observer agreement of TILs assessment using a standardized method, as proposed by the International TILs Working Group 2014, applied to a cohort of breast cancers reflecting an average breast cancer population. MATERIAL AND METHODS: Stromal TILs were assessed using full slide sections from 124 breast cancers with varying histology, malignancy grade and ER- and HER2 status. TILs were estimated by nine dedicated breast pathologists using scanned hematoxylin-eosin stainings. TILs results were categorized using various cutoffs, and the inter-observer agreement was evaluated using the intraclass coefficient (ICC), Kappa statistics as well as individual overall agreements with the median value of TILs. RESULTS: Evaluation of TILs led to an ICC of 0.71 (95% CI: 0.65-0.77) corresponding to an acceptable agreement. Kappa values were in the range of 0.38-0.46 corresponding to a fair to moderate agreement. The individual agreements increased, when using only two categories ('high' vs. 'low' TILs) and a cutoff of 50-60%. DISCUSSION: The results of the present study are in accordance with previous studies, and shows that the proposed methodology for standardized evaluation of TILs renders an acceptable inter-observer agreement. The findings, however, indicate that assessment of TILs needs further refinement, and is in support of the latest St. Gallen Consensus, that routine reporting of TILs for early breast cancer is not ready for implementation in a clinical setting.

PMID- 29168430 TI - Triple negative breast cancer - prognostic role of immune-related factors: a systematic review. AB - PURPOSE: Treatment of breast cancer has been increasingly successful in recent years with the advent of HER2-receptor targeted treatment and endocrine treatment. However, the triple negative subgroup of breast cancer (TNBC) (estrogen-, progesterone- and HER2-receptor negative) still lacks targeted treatment options. TNBC is a type of breast cancer that often affects younger women, and generally has a worse prognosis than other types of breast cancer. Recently, the complex role of the immune system in cancer growth, elimination and metastasis has been the object of increased attention. There is hope that a more detailed understanding of the intricate roles of the constituents of the immune system, will hold potential both as prognostic or predictive markers of cancer progression, but also as treatment targets for a wide range of tumors, including TNBC. The aim of this review is to provide an overview of the cellular immune microenvironment in TNBC, and to highlight areas in which TNBC may differ from other types of breast cancer. MATERIAL AND METHODS: A search of PubMed was made using the terms 'triple negative breast cancer' and 'tumor infiltrating lymphocytes', 'CD8', 'CD4', 'B cells', 'natural killer cells', 'macrophages', myeloid derived suppressor cells', 'dendritic cells', 'immune check point inhibitor', 'CTLA-4' and 'PD-L1'. RESULTS: We find that whilst factors such as TILs and certain subgroups of TILs (e.g., CD8 + and regulator T-cells) have been extensively researched, none of these markers are currently applicable to routine clinical practice. Also, TNBC differs from other types of breast cancer with regards to cellular composition of the immune infiltrate and PD-L1 expression, and the prognostic significance of these. CONCLUSIONS: Immune-related factors have the potential as both prognostic and predictive biomarkers for new treatments targeting the immune system in breast cancer. However, multivariate analyses, taking other well-known factors into account, are required to determine the true value of these biomarkers. Also, differences between TNBC and other types of breast cancer may have implications for treatment and use of immune related factors as biomarkers. PMID- 29168432 TI - Bayesian latent time joint mixed effect models for multicohort longitudinal data. AB - Characterization of long-term disease dynamics, from disease-free to end-stage, is integral to understanding the course of neurodegenerative diseases such as Parkinson's and Alzheimer's, and ultimately, how best to intervene. Natural history studies typically recruit multiple cohorts at different stages of disease and follow them longitudinally for a relatively short period of time. We propose a latent time joint mixed effects model to characterize long-term disease dynamics using this short-term data. Markov chain Monte Carlo methods are proposed for estimation, model selection, and inference. We apply the model to detailed simulation studies and data from the Alzheimer's Disease Neuroimaging Initiative. PMID- 29168434 TI - Changes in knee shape and geometry resulting from total knee arthroplasty. AB - Changes in knee shape and geometry resulting from total knee arthroplasty can affect patients in numerous important ways: pain, function, stability, range of motion, and kinematics. Quantitative data concerning these changes have not been previously available, to our knowledge, yet are essential to understand individual experiences of total knee arthroplasty and thereby improve outcomes for all patients. The limiting factor has been the challenge of accurately measuring these changes. Our study objective was to develop a conceptual framework and analysis method to investigate changes in knee shape and geometry, and prospectively apply it to a sample total knee arthroplasty population. Using clinically available computed tomography and radiography imaging systems, the three-dimensional knee shape and geometry of nine patients (eight varus and one valgus) were compared before and after total knee arthroplasty. All patients had largely good outcomes after their total knee arthroplasty. Knee shape changed both visually and numerically. On average, the distal condyles were slightly higher medially and lower laterally (range: +4.5 mm to -4.4 mm), the posterior condyles extended farther out medially but not laterally (range: +1.8 to -6.4 mm), patellofemoral distance increased throughout flexion by 1.8-3.5 mm, and patellar thickness alone increased by 2.9 mm (range: 0.7-5.2 mm). External femoral rotation differed preop and postop. Joint line distance, taking cartilage into account, changed by +0.7 to -1.5 mm on average throughout flexion. Important differences in shape and geometry were seen between pre-total knee arthroplasty and post-total knee arthroplasty knees. While this is qualitatively known, this is the first study to report it quantitatively, an important precursor to identifying the reasons for the poor outcome of some patients. Using the developed protocol and visualization techniques to compare patients with good versus poor clinical outcomes could lead to changes in implant design, implant selection, component positioning, and surgical technique. Recommendations based on this sample population are provided. Intraoperative and postoperative feedback could ultimately improve patient satisfaction. PMID- 29168431 TI - Nucleolin phosphorylation regulates PARN deadenylase activity during cellular stress response. AB - Nucleolin (NCL) is an abundant stress-responsive, RNA-binding phosphoprotein that controls gene expression by regulating either mRNA stability and/or translation. NCL binds to the AU-rich element (ARE) in the 3'UTR of target mRNAs, mediates miRNA functions in the nearby target sequences, and regulates mRNA deadenylation. However, the mechanism by which NCL phosphorylation affects these functions and the identity of the deadenylase involved, remain largely unexplored. Earlier we demonstrated that NCL phosphorylation is vital for cell cycle progression and proliferation, whereas phosphorylation-deficient NCL at six consensus CK2 sites confers dominant-negative effect on proliferation by increasing p53 expression, possibly mimicking cellular DNA damage conditions. In this study, we show that NCL phosphorylation at those CK2 consensus sites in the N-terminus is necessary to induce deadenylation upon oncogenic stimuli and UV stress. NCL-WT, but not hypophosphorylated NCL-6/S*A, activates poly (A)-specific ribonuclease (PARN) deadenylase activity. We further demonstrate that NCL interacts directly with PARN, and under non-stress conditions also forms (a) complex (es) with factors that regulate deadenylation, such as p53 and the ARE-binding protein HuR. Upon UV stress, the interaction of hypophosphorylated NCL-6/S*A with these proteins is favored. As an RNA-binding protein, NCL interacts with PARN deadenylase substrates such as TP53 and BCL2 mRNAs, playing a role in their downregulation under non-stress conditions. For the first time, we show that NCL phosphorylation offers specificity to its protein-protein, protein-RNA interactions, resulting in the PARN deadenylase regulation, and hence gene expression, during cellular stress responses.

PMID- 29168435 TI - A continuous assay for monitoring the synthetic and proofreading activities of multiple aminoacyl-tRNA synthetases for high-throughput drug discovery. AB - Aminoacyl-tRNA synthetases (aaRSs) catalyze the aminoacylation of tRNAs to produce the aminoacyl-tRNAs (aa-tRNAs) required by ribosomes for translation of the genetic message into proteins. To ensure the accuracy of tRNA aminoacylation, and consequently the fidelity of protein synthesis, some aaRSs exhibit a proofreading (editing) site, distinct from the aa-tRNA synthetic site. The aaRS editing site hydrolyzes misacylated products formed when a non-cognate amino acid is used during tRNA charging. Because aaRSs play a central role in protein biosynthesis and cellular life, these proteins represent longstanding targets for therapeutic drug development to combat infectious diseases. Most existing aaRS inhibitors target the synthetic site, and it is only recently that drugs targeting the proofreading site have been considered. In the present study, we developed a robust assay for the high-throughput screening of libraries of inhibitors targeting both the synthetic and the proofreading sites of up to four aaRSs simultaneously. Thus, this assay allows for screening of eight distinct enzyme active sites in a single experiment. aaRSs from several prominent human pathogens (i.e., Mycobacterium tuberculosis, Plasmodium falciparum, and Escherichia coli) were used for development of this assay. PMID- 29168437 TI - High-ACE Low Wage Workers: Occupational Health Nursing Research and Praxis Through a Trauma-Informed Lens. AB - Individuals with a history of adverse childhood experiences (ACEs) disproportionately have poor mental and physical health outcomes. These experiences affect individuals across the life span extending beyond health with deleterious impact on work-related outcomes. Low-wage workers are particularly at risk. Social service and health organizations are becoming aware of the extent to which the populations they serve have been affected by these experiences. Employment support programs may serve high-ACE individuals but likely are unaware of their histories and the developmental or health deficits that result and can impinge on successful employment. Occupational health nurses may be well positioned not only to implement trauma-informed care in workplaces but also to influence the ways in which employment services for this vulnerable group are delivered. The purpose of this article is to consider how ACEs could affect vulnerable workers. The need for trauma-informed research and praxis to advance occupational health nursing is discussed. PMID- 29168438 TI - IMPACT OF SEX COMPOSITION OF LIVING CHILDREN AND COUPLES' AGREEMENT ON SUBSEQUENT FERTILITY IN INDIA. AB - SummaryThe desire for children could be considered a reliable predictor of subsequent fertility. At the same time, the sex composition of surviving children, along with other demographic and socioeconomic factors, may affect a couple's fertility desire and, therefore, their subsequent fertility. This study examined the impact of the sex composition of living children and a couple's agreement on fertility desire on their subsequent fertility in India using data came from two rounds of nationally representative surveys: the India Human Development Survey (IHDS)-I (2004-05) and IHDS-II (2011-12). To understand which factors affect the chances of an additional pregnancy or childbirth, a random effects logistic regression model was applied to the panel data. It was found that the fertility desires of both marital partners were important in determining the chances of subsequent fertility. About 35% of the couples wanting to limit children had undergone pregnancy or childbirth, while 76% of the couples wanting more children had conceived or given birth to children. In the case of discordance between the spouses, subsequent fertility was found to remain intermediate between those agreeing to continue childbirth and those wanting to limit it. The findings also affirmed that child sex preference, specifically son preference, still persists in Indian society. More than 80% of the couples with only daughters in IHDS-I mutually wanted to have additional children, whereas in families that only had sons, the chance of a subsequent pregnancy was inversely associated with the number of sons. Strong patriarchal settings, combined with cultural and socioeconomic factors, affect the persistence of sex preference in India. Programmes aimed at increasing family planning use need to address son preference and should include components that promote the value of girl children. PMID- 29168440 TI - WOMEN'S EMPOWERMENT AND GENDER INEQUALITY IN ADOLESCENT NUTRITIONAL STATUS: EVIDENCE FROM THE INDONESIAN FAMILY LIFE SURVEY. AB - SummaryIn contrast to the extensive knowledge on the association between women's empowerment and the nutritional status of children under the age of five, relatively little is known about the influence of women's empowerment on adolescents' nutritional status. This study aimed to assess the association between women's empowerment and gender inequalities in adolescent nutritional status. Data were from the Indonesian Family Life Survey (IFLS) covering the period 1997 to 2015, and consisted of 16,683 observations from 13,396 adolescents between the ages of 10 and 19 years born in 6781 families. Three indicators of women's empowerment were used: mother's education, mother's bargaining power and mother's working status. Multivariate linear regression with robust standard errors was used to examine whether and how these indicators of women's empowerment influenced adolescent nutritional status. Interaction terms were added to analyse how the association between women's empowerment and adolescent nutritional status differed by gender. The results showed that mother's education and mother's working status were significantly associated with adolescent nutritional status, particularly with height-for-age. Adolescents of well educated mothers had a higher height-for-age while those who were raised by mothers with a blue-collar job had a lower height-for-age. Although no gender differences were found for height-for-age, gender differences for BMI-for-age were obvious, with boys having a lower BMI-for-age than girls. Interactions between indicators of mother's empowerment and gender showed that the gender gap in BMI-for-age was smaller for adolescents of more educated mothers. However, further analyses of food consumption patterns showed that boys whose mothers were more educated consumed more fast food and had higher instant noodle consumption than girls, thus suggesting gender bias in new disguise. PMID- 29168439 TI - Drivers of measles mortality: the historic fatality burden of famine in Bangladesh. AB - Measles is a major cause of childhood morbidity and mortality in many parts of the world. Estimates of the case-fatality rate (CFR) of measles have varied widely from place to place, as well as in the same location over time. Amongst populations that have experienced famine or armed conflict, measles CFR can be especially high, although past work has mostly focused on refugee populations. Here, we estimate measles CFR between 1970 and 1991 in a rural region of Bangladesh, which experienced civil war and famine in the 1970s. We use historical measles mortality data and a mechanistic model of measles transmission to estimate the CFR of measles. We first demonstrate the ability of this model to recover the CFR in the absence of incidence data, using simulated mortality data. Our method produces CFR estimates that correspond closely to independent estimates from surveillance data and we can capture both the magnitude and the change in CFR suggested by these previous estimates. We use this method to quantify the sharp increase in CFR that resulted in a large number of deaths during a measles outbreak in the region in 1976. Most of the children who died during this outbreak were born during a famine in 1974, or in the 2 years preceding the famine. Our results suggest that the period of turmoil during and after the 1971 war and the sustained effects of the famine, is likely to have contributed to the high fatality burden of the 1976 measles outbreak in Matlab. PMID- 29168441 TI - Detection of HEV-specific antibodies in four non-human primate species, including great apes, from different zoos in Germany. AB - The hepatitis E virus (HEV) has been described in humans and various animal species in different regions of the world. However, the knowledge on natural HEV infection in non-human primates and the corresponding risk of zoonotic transmission is scarce. To determine whether primates in captivity are affected by HEV infection, we investigated 259 individual sera of clinically healthy non human primates of 14 species from nine German zoos. Using a commercial double antigen-sandwich ELISA and a commercial IgG ELISA, 10 animals (3.9%) reacted positive in at least one assay. Three ape species and one Old World monkey species were among the seropositive animals: bonobo (Pan paniscus), gorilla (Gorilla gorilla gorilla), lar gibbon (Hylobates lar) and drill (Mandrillus leucophaeus). Testing for anti-HEV-IgM antibodies by commercial ELISA and for viral RNA by reverse-transcription real-time polymerase chain reaction resulted in negative results for all animals indicating the absence of acute HEV infections. In the past, no clinical signs of hepatitis were recorded for the seropositive animals. The results suggest that non-human primates in zoos can get naturally and subclinically infected with HEV or related hepeviruses. Future studies should evaluate potential sources and transmission routes of these infections and their impact on human health. PMID- 29168442 TI - Seasonality of urinary tract infections in the United Kingdom in different age groups: longitudinal analysis of The Health Improvement Network (THIN). AB - Evidence regarding the seasonality of urinary tract infection (UTI) consultations in primary care is conflicting and methodologically poor. To our knowledge, this is the first study to determine whether this seasonality exists in the UK, identify the peak months and describe seasonality by age. The monthly number of UTI consultations (N = 992 803) and nitrofurantoin and trimethoprim prescriptions (N = 1 719 416) during 2008-2015 was extracted from The Health Improvement Network (THIN), a large nationally representative UK dataset of electronic patient records. Negative binomial regression models were fitted to these data to investigate seasonal fluctuations by age group (14-17, 18-24, 25-45, 46-69, 70 84, 85+) and by sex, accounting for a change in the rate of UTI over the study period. A September to November peak in UTI consultation incidence was observed for ages 14-69. This seasonality progressively faded in older age groups and no seasonality was found in individuals aged 85+, in whom UTIs were most common. UTIs were rare in males but followed a similar seasonal pattern than in females. We show strong evidence of an autumnal seasonality for UTIs in individuals under 70 years of age and a lack of seasonality in the very old. These findings should provide helpful information when interpreting surveillance reports and the results of interventions against UTI. PMID- 29168444 TI - Prevalence and molecular identification of Trichinella species isolated from wildlife originating from Limpopo and Mpumalanga provinces of South Africa. AB - Trichinella species are widely distributed on all continents with the exception of Antarctica, although the full spectrum of Trichinella species found in sub Saharan African countries, and their hosts, has not been fully documented. This study was conducted to determine the prevalence of Trichinella in wildlife from the Greater Kruger National Park (GKNP) and adjacent areas located in the Limpopo and Mpumalanga provinces of South Africa, and to identify the species and/or genotypes of Trichinella larvae isolated from muscle tissues, using molecular techniques. A review of Trichinella spp. and their wildlife hosts reported during 1964-2011 was also conducted and the results were compared with our current study. Ninety samples representing 15 mammalian, two bird and three reptile species were screened for Trichinella infection during 2012-2016, using artificial digestion. Isolates detected were identified using a multiplex polymerase chain reaction (PCR) amplification of the internal transcriber spacers ITS1 and ITS2, and expansion segment V (ESV) regions of ribosomal DNA, followed by molecular analysis of the sequences. Twenty samples from seven wildlife species were positive for Trichinella spp. larvae, with an overall prevalence of 21.1% (20/90). The prevalence was higher in carnivores (18.9%, 18/90) than in omnivores (2.2%, 2/90). Analysis of sequences showed that eight of the isolates - two from spotted hyaena (Crocuta crocuta) (2/8), three from lion (Panthera leo) (3/13), one from leopard (Panthera pardus) (1/6), one from small spotted genet (Genetta genetta) (1/2) and one Nile monitor lizard (Varanus niloticus) (1/2) - conformed to Trichinella zimbabwensis. One isolate from a hyaena was grouped under the encapsulated species clade comprising T. nelsoni and genotype Trichinella T8 reported to be present in South Africa. This is the first report confirming natural infection by T. zimbabwensis in hyaena, leopard, genet and Nile monitor lizard, adding to the body of knowledge on the epidemiology of Trichinella infections in the Greater Kruger National Park of South Africa. Ten Trichinella-like larval isolates recovered after digestion from four wildlife species in this study (2012-2016) revealed inconclusive results due to DNA degradation resulting from poor storage or too few larvae for analysis, in comparison to 20 unidentified isolates from five wildlife species during the 1964 2011 period. PMID- 29168443 TI - Francisella tularensis in muscle from diseased hares - a risk factor for humans? AB - Tularemia caused by the bacterium Francisella tularensis is a zoonotic disease. Tularemia is a common disease in the hare, and as a game species can be an important source of infection for humans. In this study, hares diagnosed with tularemia were examined with the aim to investigate whether the muscle (meat) had any pathological changes and/or contained F. tularensis. Real-time PCR and/or immunohistochemistry (IHC) detected the bacteria in muscle samples from 40 out of 43 investigated hares. IHC showed that bacteria were few and most commonly located in the peri- and endomysium. Histopathology showed occasional perimysial necroses and mild inflammation in association to the bacteria. Attempts to culture from 14 muscle samples were successful in two cases, both stored in the freezer <1 year. The result of this study shows that since F. tularensis is present in the muscle of infected hares, there is a risk for human infection when consuming undercooked hare meat. The risk is enhanced by the fact that some hares do not have easily detected gross lesions. The study contributes to a better understanding of sources of infection and risk factors for humans to contract tularemia. PMID- 29168445 TI - Strengthened Ebola surveillance in France during a major outbreak in West Africa: March 2014-January 2016. AB - : Introduction An unprecedented outbreak of Ebola virus diseases (EVD) occurred in West Africa from March 2014 to January 2016. The French Institute for Public Health implemented strengthened surveillance to early identify any imported case and avoid secondary cases. METHODS: Febrile travellers returning from an affected country had to report to the national emergency healthcare hotline. Patients reporting at-risk exposures and fever during the 21st following day from the last at-risk exposure were defined as possible cases, hospitalised in isolation and tested by real-time polymerase chain reaction. Asymptomatic travellers reporting at-risk exposures were considered as contact and included in a follow-up protocol until the 21st day after the last at-risk exposure. RESULTS: From March 2014 to January 2016, 1087 patients were notified: 1053 were immediately excluded because they did not match the notification criteria or did not have at-risk exposures; 34 possible cases were tested and excluded following a reliable negative result. Two confirmed cases diagnosed in West Africa were evacuated to France under stringent isolation conditions. Patients returning from Guinea (n = 531; 49%) and Mali (n = 113; 10%) accounted for the highest number of notifications. CONCLUSION: No imported case of EVD was detected in France. We are confident that our surveillance system was able to classify patients properly during the outbreak period.

PMID- 29168447 TI - A brief summary of the epidemiology and genetic relatedness of avian influenza H9N2 virus in birds and mammals in the Middle East and North Africa. AB - H9N2 is the most widespread avian influenza virus subtype in poultry worldwide. It infects a broad spectrum of host species including birds and mammals. Infections in poultry and humans vary from silent to fatal. Importantly, all AIV, which are fatal in humans (e.g. H5N1, H7N9) acquired their 'internal' gene segments from H9N2 viruses. Although H9N2 is endemic in the Middle East (ME) and North Africa since the late 1990s, little is known about its epidemiology and genetics on a regional level. In this review, we summarised the epidemiological situation of H9N2 in poultry and mammals in Iran, Iraq, Kuwait, Qatar, United Arab Emirates, Oman, Bahrain, Yemen, Saudi Arabia, Jordan, Palestine, Israel, Syria, Lebanon, Turkey, Egypt, Sudan, Libya, Tunisia, Algeria and Morocco. The virus has been isolated from humans in Egypt and serosurveys indicated widespread infection particularly among poultry workers and pigs in some countries. Some isolates replicated well in experimentally inoculated dogs, mice, hamsters and ferrets. Insufficient protection of immunised poultry was frequently reported most likely due to concurrent viral or bacterial infections and antigenic drift of the field viruses from outdated vaccine strains. Genetic analysis indicated several distinct phylogroups including a panzootic genotype in the Asian and African parts of the ME, which may be useful for the development of vaccines. The extensive circulation of H9N2 for about 20 years in this region where the H5N1 virus is also endemic in some countries, poses a serious public health threat. Regional surveillance and control strategy are highly recommended. PMID- 29168448 TI - A competitive enzyme-linked immunosorbent assay for rapid detection of antibodies against Trichinella spiralis and T. britovi - one test for humans and swine. AB - Infection with parasites from the Trichinella genus occurs in many vertebrates but disease only occurs in humans (trichinellosis). Humans are infected after the consumption of raw or undercooked meat from infected wild or domestic animals (usually swine or horses). Using the monoclonal antibody (mAb) 7C2C5, specific for an epitope unique to the muscle larvae of the genus Trichinella, we have developed a competitive enzyme-linked immunosorbent assay (c-ELISA) that enables the rapid detection of Trichinella-specific antibodies in sera originating from two different host species (human, swine) infected with either Trichinella spiralis or Trichinella britovi. This novel c-ELISA exhibited 100% specificity and sensitivity, as confirmed by a Western blot test. The assay is easy to use (one incubation step), and the time required for the procedure (45 min) is shorter than in any other ELISA format. This test could be useful for both the detection and surveillance of Trichinella infections. PMID- 29168449 TI - Barcoding in trypanosomes. AB - Trypanosomes (genus Trypanosoma) are parasites of humans, and wild and domestic mammals, in which they cause several economically and socially important diseases, including sleeping sickness in Africa and Chagas disease in the Americas. Despite the development of numerous molecular diagnostics and increasing awareness of the importance of these neglected parasites, there is currently no universal genetic barcoding marker available for trypanosomes. In this review we provide an overview of the methods used for trypanosome detection and identification, discuss the potential application of different barcoding techniques and examine the requirements of the 'ideal' trypanosome genetic barcode. In addition, we explore potential alternative genetic markers for barcoding Trypanosoma species, including an analysis of phylogenetically informative nucleotide changes along the length of the 18S rRNA gene. PMID- 29168450 TI - Estimates of the burden of illness for eight enteric pathogens associated with animal contact in Canada. AB - Enteric pathogens are commonly known to be transmitted through food or water; however, contact with animals is another important transmission route. This study estimated the annual burden of illness attributable to animal contact for eight enteric pathogens in Canada. Using data from a Canadian expert elicitation on transmission routes, the proportion of enteric illnesses attributable to animal contact was estimated for each pathogen to estimate the annual number of illnesses, hospitalizations and deaths in Canada. For each estimate, a mean and probability intervals were generated. Of all illnesses caused by these eight pathogens, 16% were estimated attributable to animal contact. This estimate translates to 86 000 (31 000-166 000) illnesses, 488 (186-890) hospitalizations and 12 (2-28) deaths annually for the eight pathogens combined. Campylobacter spp. is the leading cause of illnesses annually, with an estimated 38 000 (14 000 71 000) illnesses occurring each year, followed by non-typhoidal Salmonella spp. (17 000, 6000-32 000). The majority of hospitalizations were attributable to non typhoidal Salmonella spp. (36%) and Campylobacter spp. (31%). Non-typhoidal Salmonella spp. (28%) and Listeria monocytogenes (31%) were responsible for the majority of the estimated deaths. These results identify farm animal and pet/pet food exposure as key pathways of transmission for several pathogens. The estimated burden of illness associated with animal contact is substantial. PMID- 29168451 TI - Intraindividual Cognitive Variability: An Examination of ANAM4 TBI-MIL Simple Reaction Time Data from Service Members with and without Mild Traumatic Brain Injury. AB - OBJECTIVES: The Automated Neuropsychological Assessment Metrics 4 TBI-MIL (ANAM4) is a computerized cognitive test often used in post-concussion assessments with U.S. service members (SMs). However, existing evidence remains mixed regarding ANAM4's ability to identify cognitive issues following mild traumatic brain injury (mTBI). Studies typically examine ANAM4 using standardized scores and/ or comparisons to a baseline. A more fine-grained approach involves examining inconsistency within an individual's performance (i.e., intraindividual variability). METHODS: Data from 237 healthy control SMs and 105 SMs within seven days of mTBI who took the ANAM4 were included in analyses. Using each individual's raw scores on a simple reaction time (RT) subtest (SRT1) that is repeated at the end of the battery (SRT2), we calculated mean raw RT and the intraindividual standard deviation (ISD) of trial-by-trial RT. Analyses investigated differences between groups in mean RT, RT variability (i.e., ISD), and change in ISD from SRT1 and SRT2. RESULTS: Using regression residuals to control for demographic variables, analysis of variance, and pairwise comparisons revealed the control group had faster mean RT and smaller ISD compared to the mTBI group. Furthermore, the mTBI group had a significant increase in ISD from SRT1 to SRT2, with effect sizes exceeding the minimum practical effect for comparisons of ISD in SRT2 and change in ISD from SRT1 to SRT2. CONCLUSIONS: While inconsistencies in performance are often viewed as test error, the results suggest intraindividual cognitive variability may be more sensitive than traditional metrics in detecting changes in cognitive function after mTBI. Additionally, the findings highlight the utility of the ANAM4's repeating a RT subtest at two points in the same session for exploring within-subject differences in performance variability.

AB - Approximately three per cent of the world's population (170-200 million people) is chronically infected with hepatitis C virus (HCV) and almost 500,000 people die each year (mostly in lower middle-income countries) from complications secondary to HCV infection. In India, HCV infection imposes a considerable burden of mortality, morbidity and healthcare costs. In the last two decades, the treatment of HCV has evolved from interferon (IFN)-based therapies with or without ribavirin (RBV) to pegylated-IFN (PEG-IFN) and RBV-based therapies that were better tolerated by patients. However, the introduction of oral drugs, which specifically target virus-specific proteins, has now revolutionized the treatment of chronic HCV. These agents are known as direct-acting antivirals (DAAs). These drugs have resulted in very high HCV cure rates even with reduced treatment duration and an excellent tolerability by the patients compared to PEG-IFN- and RBV-based therapies. In India, sofosbuvir (SOF), one of the most effective DAAs, has been made available at a compassionate price; thus only those DAA-based management strategies, which contain SOF are adopted in India. Here, we review different DAAs and their possible roles in different genotypes and stages of liver disease, stressing upon the role of SOF. An attempt has also been made to devise strategies using SOF for the most prevalent genotypes in our country (genotypes 3 and 1) and cirrhosis.

AB - BACKGROUND & OBJECTIVES: In low- and middle-income countries such as India, a feasible public health strategy could be to ensure continuous antipsychotics and psychoeducation for those with schizophrenia. Whether such a strategy favourably influences its course and outcome is not well-studied. The objectives of this study were to examine these issues in a cohort of patients with schizophrenia in a rural south Indian taluk (an administrative block). This cohort was part of a community intervention programme running in the place since the past one decade. METHODS: A total of 201 patients were assessed after an average of four years of follow up. Psychopathology, disability and course of illness were assessed using Positive and Negative Syndrome Scale (PANSS), Indian Disability Evaluation and Assessment Scale (IDEAS) and Psychiatric and Personal History Schedule (PPHS), respectively. Interventions included ensuring continuous antipsychotic treatment and low-intensity psychoeducation. RESULTS: One hundred and forty two [70.6%; 95% confidence interval (CI): 64.35-76.95] of the 201 patients achieved clinical remission by the end of follow up period (four years); 140 (69.6%; 95% CI: 63.29 76.07) had satisfactory outcome (42.3% best outcome and 27.4% intermediate outcome). There was a significant reduction in the proportion of patients with disability [134/201 (66.7%) at baseline; 55/201 (27.3%) at follow up; PInterpretation & conclusions: Treatment with antipsychotics and psychoeducation can favourably influence the course of schizophrenia and reduce disability in a substantial proportion of patients. Structured psychosocial interventions may be indicated in the significant minority who show suboptimal outcome with this strategy. PMID- 29168459 TI - p40 & thyroid transcription factor-1 immunohistochemistry: A useful panel to characterize non-small cell lung carcinoma-not otherwise specified (NSCLC-NOS) category. AB - BACKGROUND & OBJECTIVES: Accurate histopathological subtyping of non-small cell lung carcinoma (NSCLC) is essential for targeted therapeutic agents. Immunohistochemistry (IHC) is helpful in identification of different tumour subtypes. In this study two marker approaches, one each for glandular and squamous cell differentiation was applied to maximize the proportion of accurately subtyped NSCLC not otherwise specified (NOS) tumours on small biopsy samples. METHODS: Two hundred and sixty three consecutive lung biopsies of primary lung carcinoma were prospectively studied. These were subtyped first morphologically and then by IHC for p40 and thyroid transcription factor-1 (TTF 1). The diagnosis of NSCLC-NOS before and after addition of IHC was evaluated. Results were correlated and validated with morphologically proven cases and matched surgical specimens. RESULTS: Based on morphology, only 140 of the 263 (53.2%) cases of NSCLC were characterized, whereas 123 (46.7%) were classified as NSCLC-NOS type. With addition of IHC (p40 and TTF-1), the latter category reduced to 14.4 per cent and a sum of 225 (85.5%) cases were accurately subtyped into squamous cell carcinoma, adenocarcinoma and adenosquamous carcinoma. p40 showed 100 per cent sensitivity and specificity for squamous differentiation whereas TTF 1 showed sensitivity of 85.3 per cent and specificity of 98.1 per cent. Ninety per cent correlation of morphologic subtypes was achieved with matched resected specimens. INTERPRETATION & CONCLUSIONS: Our results showed that an approach of using only a two-antibody panel (p40 and TTF-1) might help in reduction of diagnostic category of NSCLC-NOS significantly and contribute in saving tissue for future molecular testing. PMID- 29168460 TI - Molecular & genetic characteristics of Mycobacterium tuberculosis strains circulating in the southern part of West Siberia. AB - BACKGROUND & OBJECTIVES: A complicated epidemiological situation characterized by significantly high tuberculosis (TB) morbidity is observed in West Siberia. This study was aimed to investigate the genetic characteristics of Mycobacterium tuberculosis circulating in the southern part of West Siberia (in the Omsk region). METHODS: From March 2013 to January 2015, 100 isolates of M. tuberculosis were obtained from patients with pulmonary TB living in the Omsk region. Drug susceptibility testing was performed on Lowenstein-Jensen medium (absolute concentration method). Genetic typing of isolates was carried out by variable number tandem repeats of mycobacterial interspersed repetitive units (MIRU-VNTR) typing and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. The genetic types and characteristics of cluster strains were determined using 15 MIRU-VNTR loci. RESULTS: Thirty six VNTR types were found. Twenty six (26.0%) isolates had a unique profile, and the remaining 74 were grouped in 10 clusters containing from 2 to 23 isolates. The Beijing genotype was found in 72 isolates, 61 (85.0%) of which were part of five clusters that included two large clusters containing 23 isolates. Other genetic families, such as Latin-American Mediterranean (LAM, 11.0%), S family (2.0%) and Haarlem (4.0%), were also detected. The genetic family of 11 isolates could not be determined. Six different VNTR profiles were found in these non-classified isolates. Only 16 per cent of isolates were sensitive to anti-TB drugs. The katG315 (94.8%) and rpoB531 (92.2%) mutations were identified in 77 multidrug resistant M. tuberculosis isolates. INTERPRETATION & CONCLUSIONS: This study showed that the M. tuberculosis population in the Omsk region was heterogeneous. The Beijing genotype predominated and was actively spreading. The findings obtained point to the need for the implementation of more effective preventive measures to stop the spread of drug-resistant M. tuberculosis strains.

AB - BACKGROUND & OBJECTIVES: Next generation transplantation medicine aims to develop stimulating cocktail for increased ex vivo expansion of primitive hematopoietic stem and progenitor cells (HSPC). The present study was done to evaluate the cocktail GF (Thrombopoietin + Stem Cell factor + Flt3-ligand) and homing-defining molecule Stromal cell-derived factor 1 (SDF1) for HSPC ex vivo expansion. METHODS: Peripheral blood stem cell (n=74) harvests were analysed for CD34hiCD45lo HSPC. Immunomagnetically enriched HSPC were cultured for eight days and assessed for increase in HSPC, colony forming potential in vitro and in vivo engrafting potential by analyzing human CD45+ cells. Expression profile of genes for homing and stemness were studied using microarray analysis. Expression of adhesion/homing markers were validated by flow cytometry/ confocal microscopy. RESULTS: CD34hiCD45lo HSPC expansion cultures with GF+SDF1 demonstrated increased nucleated cells (n=28, P+ cells (n=8, P=0.021) and increased colony forming units (cfu) compared to unstimulated and GF-stimulated HSPC. NOD-SCID mice transplanted with GF+SDF1-HSPC exhibited successful homing/engraftment (n=24, PInterpretation & conclusions: Cocktail of cytokines and SDF1 showed good potential to successfully expand HSPC which exhibited enhanced ability to generate multilineage cells in short-term and long-term repopulation assay. This cocktail mediated stem cell expansion has potential to obviate the need for longer and large volume apheresis procedure making it convenient for donors. PMID- 29168462 TI - Potential benefit of optimizing atrioventricular & interventricular delays in patients with cardiac resynchronization therapy. AB - BACKGROUND & OBJECTIVES: The clinical benefit of optimization (OPT) of atrioventricular delay (AVD) and interventricular delay (VVD) in cardiac resynchronization therapy (CRT) remains debatable. This study was aimed to determine the influence of AVD and VVD OPT on selected parameters in patients early after CRT implantation and at mid-term follow up (FU). METHODS: Fifty two patients (61+/-10 yr, 23 males) with left bundle branch block, left ventricular ejection fraction (LVEF) <=35 per cent and heart failure were selected for CRT implantation. Early on the second day (2DFU) after CRT implantation, the patients were assigned to the OPT or the factory setting (FS) group. Haemodynamic and electrical parameters were evaluated at baseline, on 2DFU after CRT and mid-term FU [three-month FU (3MFU)]. Echocardiographic measures were assessed before implantation and at 3MFU. The AVD/VVD was deemed optimal for the highest cardiac output (CO) with impedance cardiography (ICG) monitoring. RESULTS: On 2DFU, the AVD was shorter in the OPT group, LV was paced earlier than in FS group and CO was insignificantly higher in OPT group. At 3MFU, improvement of CO was observed only in OPT patients, but the intergroup difference was not significant. At 3MFU in OPT group, reduction of LV in terms of LV end-diastolic diameter (LVeDD), LV end-systolic diameter, LV end-diastolic and systolic volume with the improvement in LVEF was observed. In FS group, only a reduction in LVeDD was present. In OPT group, the paced QRS duration was shorter than in FS group patients. INTERPRETATION & CONCLUSIONS: CRT OPT of AVD and VVD with ICG was associated with a higher CO and better reverse LV remodelling. CO monitoring with ICG is a simple, non-invasive tool to optimize CRT devices. PMID- 29168463 TI - A preliminary study of natural history of mild traumatic brain injury by using multidimensional approach. AB - BACKGROUND & OBJECTIVES: Spectrum of post-traumatic symptoms is frequent among mild traumatic brain injury (mTBI) patients. They account for symptoms in 30-80 per cent of patients during 3-4 months and 20-30 per cent of patients six months post-injury. There are no studies from India in this area. The present longitudinal study was conducted to evaluate the natural recovery of post traumatic symptoms in mTBI patients. METHODS: Twenty five mTBI patients presenting with initial Glasgow coma scale score of 15 were recruited initially 2 3 wk post-injury. All patients were followed up twice, after 3-4 and 6-7 months. The patients were evaluated with neuropsychological test, post-traumatic symptoms and quality of life after injury. RESULTS: Sustained attention and sensory registration were first to improve. Memory and executive domains improved partially until three months and then after complete recovery. However, a few facets of learning/memory did not improve even at six months. The post-traumatic symptoms decreased since baseline from 76 to 52 per cent at 3-4 months and further to 28 per cent at 6-7 months. The quality of life improved partially from baseline till 3-4 months and much more by 6-7 months. INTERPRETATION & CONCLUSIONS: The study findings showed the course of changes in cognition, traumatic symptoms and quality of life since the time of injury till 6-7 months post-injury. Though majority of post-traumatic symptoms recovered after mTBI without any intervention, but residuals were not uncommon. PMID- 29168464 TI - Sustained progress, but no room for complacency: Results of 2015 HIV estimations in India. AB - BACKGROUND & OBJECTIVES: Evidence-based planning has been the cornerstone of India's response to HIV/AIDS. Here we describe the process, method and tools used for generating the 2015 HIV estimates and provide a summary of the main results. METHODS: Spectrum software supported by the UNAIDS was used to produce HIV estimates for India as a whole and its States/Union Territories. This tool takes into consideration the size and HIV prevalence of defined population groups and programme data to estimate HIV prevalence, incidence and mortality over time as well as treatment needs. RESULTS: India's national adult prevalence of HIV was 0.26 per cent in 2015. Of the 2.1 million people living with HIV/AIDS, the largest numbers were in Andhra Pradesh, Maharashtra and Karnataka. New HIV infections were an estimated 86,000 in 2015, reflecting a decline by around 32 per cent from 2007. The declining trend in incidence was mirrored in most States, though an increasing trend was detected in Assam, Chandigarh, Chhattisgarh, Gujarat, Sikkim, Tripura and Uttar Pradesh. AIDS-related deaths were estimated to be 67,600 in 2015, reflecting a 54 per cent decline from 2007. There were variations in the rate and trend of decline across India for this indicator also. INTERPRETATION & CONCLUSIONS: While key indicators measured through Spectrum modelling confirm success of the National AIDS Control Programme, there is no room for complacency as rising incidence trends in some geographical areas and population pockets remain the cause of concern. Progress achieved so far in responding to HIV/AIDS needs to be sustained to end the HIV epidemic. PMID- 29168465 TI - Investigation of the risk factors for pulmonary tuberculosis: A case-control study among Saharia tribe in Gwalior district, Madhya Pradesh, India. AB - BACKGROUND & OBJECTIVES: Prevalence of pulmonary tuberculosis (PTB) is known to be high in the indigenous tribal community Saharia in Madhya Pradesh, India. The risk factors for PTB are not well known among them. This study was done to determine various risk factors associated with PTB in the indigenous community Saharia. METHODS: A prevalence survey was conducted among Saharias of Gwalior district of Madhya Pradesh. The population surveyed was 12,123 which was the source of cases and controls for the present study. All the bacillary-positive cases and controls in the ratio of 1:5 were included in the survey. Data were collected by the trained health workers from the patients and controls using a semi-structured pre-coded and pre-tested questionnaire which included data on risk factors including demographic factors, host-related factors and household factors. The individuals were also screened for diabetes mellitus and HIV. RESULTS: Malnutrition and history of asthma were associated with an increased risk of PTB. More than 56 per cent cases were attributed to malnutrition and 12 per cent attributed to asthma. Low family income, alcohol consumption and smoking were the other contributors. The risk was higher in males as compared to females. INTERPRETATION & CONCLUSIONS: The study emphasized that the main contributors were social factors. Nutrition supplementation, especially in tuberculosis (TB) patients and integrated approach to improve their living conditions are needed to control TB in this community. PMID- 29168466 TI - New Delhi metallo-beta-lactamase - type carbapenemases producing Escherichia coli isolates from hospitalized patients: A pilot study. AB - BACKGROUND & OBJECTIVES: Resistances to carbapenem group of antimicrobials among Escherichia coli due to production of carbapenemases, especially the New Delhi metallo-beta-lactamase (NDM) types, pose serious challenges in the treatment of infections in healthcare settings. This study was undertaken to detect NDM producing E. coli isolates from hospitalized patients with urinary tract infection (UTI). METHODS: A total of 30 non-repetitive isolates of E. coli from hospitalized patients with clinical suspicion of UTI were subjected to antimicrobial susceptibility testing. Screening for the production of extended spectrum beta-lactamases (ESBL) was carried out by minimum inhibitory concentration (MIC) test strip ESBL followed by phenotypic confirmation by double disc synergy test. Phenotypic confirmation of carbapenemase production was carried out by MIC test strip metallo-beta-lactamases. Molecular identification of the blaNDM gene was carried out by polymerase chain reaction (PCR) and sequencing of the amplified fragment. RESULTS: Seventeen of the 30 isolates were detected as ESBL producers, of which three were found to be carbapenemase producers. NDM genes were detected by PCR followed by gene sequencing in all three isolates positive for ESBL as well as carbapenemase. The amino acid sequence of the three isolates showed complete identity to the reference sequences of NDM-1, NDM-4 and NDM-8, respectively. INTERPRETATION & CONCLUSIONS: Our study showed the circulation of NDM variants among the clinical isolates of E. coli that were producers of ESBL as well as carbapenemase. PMID- 29168467 TI - Temporal trends of intestinal parasites in patients attending a tertiary care hospital in south India: A seven-year retrospective analysis. AB - BACKGROUND & OBJECTIVES: Intestinal parasitic infections and their associated complications are a major cause of morbidity in the developing world. This retrospective study was done to assess the prevalence of intestinal parasitic infections among patients in a tertiary healthcare setting and to analyze age-, gender- and time-related trends in the prevalence of these intestinal parasites over a seven year period (2006-2012). METHODS: The presence of various intestinal parasites in a tertiary care setting over a seven year period in different age groups was determined by performing routine stool microscopy. Modified acid-fast staining was performed for stool samples collected from children less than five years of age for the detection of intestinal coccidian parasites. Statistical analysis was carried out to analyze age-related trends in relation to the prevalence of commonly detected intestinal parasites. Seasonal fluctuations in parasite prevalence were evaluated by performing harmonic regression analysis. RESULTS: A total of 257,588 stool samples were received over the seven year period for examination. The highest percentage of intestinal parasites was in the 6-10 yr age group. Among the intestinal parasites, Giardia intestinalis had the highest prevalence across most age groups, except in those above 60 yr of age where hookworm became more prevalent. A significant decreasing trend with age was observed for G. intestinalis, whereas for hookworm and Strongyloides stercoralis, an increasing trend with age was seen. Significant linear temporal trends were observed for parasites such as G. intestinalis, Entamoeba histolytica and Ascaris lumbricoides. INTERPRETATION & CONCLUSIONS: While G. intestinalis was more common in the younger age groups, certain soil-transmitted helminths such as hookworm and S. stercoralis showed a higher prevalence in the older populations. Significant temporal trends and seasonality were observed for some of the common intestinal parasites. PMID- 29168468 TI - Strontium chloride hexahydrate as a candidate molecule for long-term treatment of allergic rhinitis. AB - BACKGROUND & OBJECTIVES: Neurogenic inflammation plays a role in the pathophysiology of allergic rhinitis (AR). Strontium salts are highly effective in reducing the sensory irritation. This study was aimed to investigate the efficacy of strontium chloride (SC) on AR symptoms based on the duration of SC use before the symptoms begin. METHODS: Wistar albino rats (n=18) were randomly divided into three groups: Group 1, received 1MUg mometasone furoate (MF); Group 2, three per cent SC; and Group 3 received five per cent SC (2 MUl/site). Drugs were administered to the each nasal cavity for three weeks every morning. On the days 7, 14 and 21, histamine dihydrochloride (HD) 5 MUmol (2 MUl/site) was administered and the frequencies of nasal rubbing and sneezing were counted for 15 min. RESULTS: After 7, 14 and 21 day medication period, the groups were compared in terms of the frequency of sneezing and nasal rubbing following HD. There was a significant difference among the groups in terms of the frequency of sneezing on the day 7 (PPInterpretation & conclusions: Our results showed that three and five per cent SC were less effective than MF for sneezing during the first week, but the efficiency was equal to that of MF after the first 14 days. Long-term use of SC was as effective as MF on nasal rubbing. SC can be as effective as MF on both sneezing and nasal rubbing on regular use over three weeks. PMID- 29168469 TI - Bisphenol A-induced ultrastructural changes in the testes of common marmoset. AB - BACKGROUND & OBJECTIVES: Bisphenol A (BPA) is an endocrine disruptor that is widely used in the manufacture of polycarbonate plastics, epoxy resins and dental sealants. It is known to have adverse effects on spermatogenesis in rodents. This study was aimed to evaluate the effects of BPA in adult common marmoset owing to its similarities with human spermatogenesis. METHODS: Sixteen marmosets were divided into four groups (n=4 per group) and given oral doses of BPA (2.5, 12.5 and 25 MUg/kg BW/day) for 70 days to cover two spermatogenic cycles, and the control group received only vehicle (honey). Testes were processed for histological and transmission electron microscopy studies. RESULTS: Histology of the testis showed sloughing of germ cells into the lumen, increase in interstitial space and vacuolation of Sertoli cell cytoplasm. Ultrastructural analysis of the testis revealed several degenerative effects on the basement membrane, Sertoli cells, Leydig cells and other developing germ cells in the 12.5 and 25 MUg/kg BW/day groups as compared to control. INTERPRETATION & CONCLUSIONS: The observed ultrastructural changes caused by BPA in testicular morphology might be indicative of a perturbed sperm production. Considering the genetic and spermatogenic similarities of common marmoset (Callithrix jacchus) and humans, the study findings are of significance. Further studies are, however, needed to elucidate the mechanism of action. PMID- 29168470 TI - Seroepidemiology of parvovirus B19 among different age groups & pregnant women in India.

PMID- 29168472 TI - Characterization of naturally occurring pentacyclic triterpenes as novel inhibitors of deubiquitinating protease USP7 with anticancer activity in vitro. AB - Deubiquitinating protease USP7 is a promising therapeutic target for cancer treatment, and interest in developing USP7 inhibitors has greatly increased. In the present study, we reported a series of natural pentacyclic triterpenes with USP7 inhibitory activity in vitro. Among them, both the ursane triterpenes and oleanane triterpenes were more active than the lupine triterpenes, whereas ursolic acid was the most potent with IC50 of 7.0+/-1.5 MUmol/L. Molecular docking studies showed that ursolic acid might occupy the ubiquitin binding pocket of USP7, with the 17-carboxyl group and 3-hydroxyl group playing a vital role in the USP7-ursolic acid interaction. Using the cellular thermal shift assay, we demonstrated that ursolic acid interacted with USP7 in RPMI8226 human myeloma cells. Ursolic acid dose-dependently inhibited the proliferation of the myeloma cells with IC50 of 6.56 MUmol/L, accompanied by reductions in USP7 substrates such as MDM2, UHRF1 and DNMT1. Overexpression of USP7 partially, but significantly attenuated ursolic acid-induced cell death as well as downregulation of MDM2, UHRF1 and DNMT1. In conclusion, we demonstrate for the first time that pentacyclic triterpenes represent a novel scaffold for developing USP7 inhibitors and that USP7 inhibition contributes to the anti-cancer effect of ursolic acid. PMID- 29168473 TI - Yangxin Tongmai Formula ameliorates impaired glucose tolerance in children with Graves' disease through upregulation of the insulin receptor levels. AB - Graves' disease (GD) is the leading cause of hyperthyroidism, and the majority of GD patients eventually develop disorders of glucose handling, which further affects their quality of life. Yangxin Tongmai formula (YTF) is modified from a famous formula of traditional Chinese medicine for the treatment of cardiovascular diseases. In this study we investigated the potential effects of YTF in the treatment of pediatric GD patients with impaired glucose tolerance. Forty pediatric GD patients and 20 healthy children were recruited for this clinical study. Based on the glucose tolerance, the GD patients were divided into two groups: 20 patients displayed impaired glucose tolerance, while the other 20 patients displayed normal glucose tolerance. YTF was orally administered for 60 days. YTF administration significantly ameliorated the abnormal glucose tolerance and insulin sensitivity in the GD patients with impaired glucose tolerance. To determine the molecular mechanisms of this observation, the number of plasma insulin receptors was determined by ELISA. Before treatment, the fasting and postprandial levels of the insulin receptor were significantly lower in patients with impaired glucose tolerance compared with those in patients with normal glucose tolerance and healthy children. After YTF treatment, both the fasting and the postprandial circulating insulin receptor levels were upregulated, and close to those in healthy children. Therefore, YTF is a potential effective treatment to enhance glucose handling in GD children with impaired glucose tolerance. PMID- 29168475 TI - Chronic kidney disease. AB - Chronic kidney disease (CKD) is defined by persistent urine abnormalities, structural abnormalities or impaired excretory renal function suggestive of a loss of functional nephrons. The majority of patients with CKD are at risk of accelerated cardiovascular disease and death. For those who progress to end-stage renal disease, the limited accessibility to renal replacement therapy is a problem in many parts of the world. Risk factors for the development and progression of CKD include low nephron number at birth, nephron loss due to increasing age and acute or chronic kidney injuries caused by toxic exposures or diseases (for example, obesity and type 2 diabetes mellitus). The management of patients with CKD is focused on early detection or prevention, treatment of the underlying cause (if possible) to curb progression and attention to secondary processes that contribute to ongoing nephron loss. Blood pressure control, inhibition of the renin-angiotensin system and disease-specific interventions are the cornerstones of therapy. CKD complications such as anaemia, metabolic acidosis and secondary hyperparathyroidism affect cardiovascular health and quality of life, and require diagnosis and treatment.

AB - Two-dimensional (2D) supramolecular arrays provide a route to the spatial control of the chemical functionality of a surface, but their deposition is in almost all cases limited to a monolayer termination. Here we investigated the sequential deposition of one 2D array on another to form a supramolecular heterostructure and realize the growth-normal to the underlying substrate-of distinct ordered layers, each of which is stabilized by in-plane hydrogen bonding. For heterostructures formed by depositing terephthalic acid or trimesic acid on cyanuric acid/melamine, we have determined, using atomic force microscopy under ambient conditions, a clear epitaxial arrangement despite the intrinsically distinct symmetries and/or lattice constants of each layer. Structures calculated using classical molecular dynamics are in excellent agreement with the orientation, registry and dimensions of the epitaxial layers. Calculations confirm that van der Waals interactions provide the dominant contribution to the adsorption energy and registry of the layers. PMID- 29168479 TI - Catalytic diastereo- and enantioselective additions of versatile allyl groups to N-H ketimines. AB - There are many biologically active organic molecules that contain one or more nitrogen-containing moieties, and broadly applicable and efficient catalytic transformations that deliver them diastereoselectively and/or enantioselectively are much sought after. Various methods for enantioselective synthesis of alpha secondary amines are available (for example, from additions to protected/activated aldimines), but those involving ketimines are much less common. There are no reported additions of carbon-based nucleophiles to unprotected/unactivated (or N-H) ketimines. Here, we report a catalytic, diastereo- and enantioselective three-component strategy for merging an N-H ketimine, a monosubstituted allene and B2(pin)2, affording products in up to 95% yield, >98% diastereoselectivity and >99:1 enantiomeric ratio. The utility of the approach is highlighted by synthesis of the tricyclic core of a class of compounds that have been shown to possess anti-Alzheimer activity. Stereochemical models developed with the aid of density functional theory calculations, which account for the observed trends and levels of enantioselectivity, are presented. PMID- 29168480 TI - Structural snapshots of concerted double E-H bond activation at a transition metal centre. AB - Bond activation at a transition metal centre is a key fundamental step in numerous chemical transformations. The oxidative addition of element-hydrogen bonds, for example, represents a critical step in a range of widely applied catalytic processes. Despite this, experimental studies defining steps along the bond activation pathway are very rare. In this work, we report on fundamental studies defining a new oxidative activation pathway: combined experimental and computational approaches yield structural snapshots of the simultaneous activation of both bonds of a beta-diketiminate-stabilized GaH2 unit at a single metal centre. Systematic variation of the supporting phosphine ligands and single crystal X-ray/neutron diffraction are exploited in tandem to allow structural visualization of the activation process, from a eta2-H,H sigma-complex showing little Ga-H bond activation, through species of intermediate geometry featuring stretched Ga-H and compressed M-H/M-Ga bonds, to a fully activated metal dihydride featuring a neutral (carbene-type) N-heterocyclic GaI ligand. PMID- 29168481 TI - Direct mapping of the angle-dependent barrier to reaction for Cl + CHD3 using polarized scattering data. AB - The transition state, which gates and modulates reactive flux, serves as the central concept in our understanding of activated reactions. The barrier height of the transition state can be estimated from the activation energy taken from thermal kinetics data or from the energetic threshold in the measured excitation function (the dependence of reaction cross-sections on initial collision energies). However, another critical and equally important property, the angle dependent barrier to reaction, has not yet been amenable to experimental determination until now. Here, using the benchmark reaction of Cl + CHD3(v1 = 1) as an example, we show how to map this anisotropic property of the transition state as a function of collision energy from the preferred reactant bond alignment of the backward-scattered products-the imprints of small impact parameter collisions. The deduced bend potential at the transition state agrees with ab initio calculations. We expect that the method should be applicable to many other direct reactions with a collinear barrier. PMID- 29168482 TI - UV-light-driven prebiotic synthesis of iron-sulfur clusters. AB - Iron-sulfur clusters are ancient cofactors that play a fundamental role in metabolism and may have impacted the prebiotic chemistry that led to life. However, it is unclear whether iron-sulfur clusters could have been synthesized on prebiotic Earth. Dissolved iron on early Earth was predominantly in the reduced ferrous state, but ferrous ions alone cannot form polynuclear iron-sulfur clusters. Similarly, free sulfide may not have been readily available. Here we show that UV light drives the synthesis of [2Fe-2S] and [4Fe-4S] clusters through the photooxidation of ferrous ions and the photolysis of organic thiols. Iron sulfur clusters coordinate to and are stabilized by a wide range of cysteine containing peptides and the assembly of iron-sulfur cluster-peptide complexes can take place within model protocells in a process that parallels extant pathways. Our experiments suggest that iron-sulfur clusters may have formed easily on early Earth, facilitating the emergence of an iron-sulfur-cluster-dependent metabolism. PMID- 29168483 TI - Bicyclic Baird-type aromaticity. AB - Classic formulations of aromaticity have long been associated with topologically planar conjugated macrocyclic systems. The theoretical possibility of so-called bicycloaromaticity was noted early on. However, it has yet to be demonstrated by experiment in a simple synthetic organic molecule. Conjugated organic systems are attractive for studying the effect of structure on electronic features. This is because, in principle, they can be modified readily through dedicated synthesis. As such, they can provide useful frameworks for testing by experiment with fundamental insights provided by theory. Here we detail the synthesis and characterization of two purely organic non-planar dithienothiophene-bridged [34]octaphyrins that permit access to two different aromatic forms as a function of the oxidation state. In their neutral forms, these congeneric systems contain competing 26 and 34 pi-electronic circuits. When subject to two-electron oxidation, electronically mixed [4n+1]/[4n+1] triplet biradical species in the ground state are obtained that display global aromaticity in accord with Baird's rule.

AB - In nature, many organisms generate large families of natural product metabolites that have related molecular structures as a means to increase functional diversity and gain an evolutionary advantage against competing systems within the same environment. One pathway commonly employed by living systems to generate these large classes of structurally related families is oligomerization, wherein a series of enzymatically catalysed reactions is employed to generate secondary metabolites by iteratively appending monomers to a growing serial oligomer chain. The polypyrroloindolines are an interesting class of oligomeric natural products that consist of multiple cyclotryptamine subunits. Herein we describe an iterative application of asymmetric copper catalysis towards the synthesis of six distinct oligomeric polypyrroloindoline natural products: hodgkinsine, hodgkinsine B, idiospermuline, quadrigemine H and isopsychotridine B and C. Given the customizable nature of the small-molecule catalysts employed, we demonstrate that this strategy is further amenable to the construction of quadrigemine H-type alkaloids not isolated previously from natural sources.

AB - The amino acid serine is known to form a very stable octamer that has properties that set it apart from serine complexes of different sizes or from complexes composed of other amino acids. For example, both singly protonated serine octamers and anionic octamers complexed with two halogen ions strongly prefer homochirality, even when assembled from racemic D,L mixtures. Consequently, the structures of these complexes are of great interest, but no acceptable candidates have so far been identified. Here, we investigate anionic serine octamers coordinated with two chloride ions using a novel technique coupling ion mobility spectrometry-mass spectrometry with infrared spectroscopy, in combination with theoretical calculations. The results allow the identification of a unique structure for (Ser8Cl2)2- that is highly symmetric, very stable and homochiral and whose calculated properties match those observed in experiments. PMID- 29168484 TI - Global profiling of lysine reactivity and ligandability in the human proteome. AB - Nucleophilic amino acids make important contributions to protein function, including performing key roles in catalysis and serving as sites for post translational modification. Electrophilic groups that target amino-acid nucleophiles have been used to create covalent ligands and drugs, but have, so far, been mainly limited to cysteine and serine. Here, we report a chemical proteomic platform for the global and quantitative analysis of lysine residues in native biological systems. We have quantified, in total, more than 9,000 lysines in human cell proteomes and have identified several hundred residues with heightened reactivity that are enriched at protein functional sites and can frequently be targeted by electrophilic small molecules. We have also discovered lysine-reactive fragment electrophiles that inhibit enzymes by active site and allosteric mechanisms, as well as disrupt protein-protein interactions in transcriptional regulatory complexes, emphasizing the broad potential and diverse functional consequences of liganding lysine residues throughout the human proteome.

AB - This corrects the article DOI: 10.1038/nchem.2551. PMID- 29168489 TI - Modular probes for enriching and detecting complex nucleic acid sequences. AB - Complex DNA sequences are difficult to detect and profile, but are important contributors to human health and disease. Existing hybridization probes lack the capability to selectively bind and enrich hypervariable, long or repetitive sequences. Here, we present a generalized strategy for constructing modular hybridization probes (M-Probes) that overcomes these challenges. We demonstrate that M-Probes can tolerate sequence variations of up to 7 nt at prescribed positions while maintaining single nucleotide sensitivity at other positions. M Probes are also shown to be capable of sequence-selectively binding a continuous DNA sequence of more than 500 nt. Furthermore, we show that M-Probes can detect genes with triplet repeats exceeding a programmed threshold. As a demonstration of this technology, we have developed a hybrid capture method to determine the exact triplet repeat expansion number in the Huntington's gene of genomic DNA using quantitative PCR. PMID- 29168490 TI - Single-crystal-to-single-crystal intercalation of a low-bandgap superatomic crystal. AB - The controlled introduction of impurities into the crystal lattice of solid-state compounds is a cornerstone of materials science. Intercalation, the insertion of guest atoms, ions or molecules between the atomic layers of a host structure, can produce novel electronic, magnetic and optical properties in many materials. Here we describe an intercalation compound in which the host [Co6Te8(PnPr3)6][C60]3, formed from the binary assembly of atomically precise molecular clusters, is a superatomic analogue of traditional layered atomic compounds. We find that tetracyanoethylene (TCNE) can be inserted into the superstructure through a single-crystal-to-single-crystal transformation. Using electronic absorption spectroscopy, electrical transport measurements and electronic structure calculations, we demonstrate that the intercalation is driven by the exchange of charge between the host [Co6Te8(PnPr3)6][C60]3 and the intercalant TCNE. These results show that intercalation is a powerful approach to manipulate the material properties of superatomic crystals. PMID- 29168492 TI - Thoroughly enthralling thulium. PMID- 29168491 TI - Structure and reactivity of a mononuclear gold(II) complex. AB - Mononuclear gold(II) complexes are very rare labile species. Transient gold(II) species have been suggested in homogeneous catalysis and in medical applications, but their geometric and electronic structures have remained essentially unexplored: even fundamental data, such as the ionic radius of gold(II), are unknown. Now, an unprecedentedly stable neutral gold(II) complex of a porphyrin derivative has been isolated, and its structural and spectroscopic features determined. The gold atom adopts a 2+2 coordination mode in between those of gold(III) (four-coordinate square planar) and gold(I) (two-coordinate linear), owing to a second-order Jahn-Teller distortion enabled by the relativistically lowered 6s orbital of gold. The reactivity of this gold(II) complex towards dioxygen, nitrosobenzene and acids is discussed. This study provides insight on the ionic radius of gold(II), and allows it to be placed within the homologous series of nd9 Cu/Ag/Au divalent ions and the 5d8/9/10 Pt/Au/Hg 'relativistic' triad in the periodic table. PMID- 29168493 TI - Site-selective oxidation, amination and epimerization reactions of complex polyols enabled by transfer hydrogenation. AB - Polyoxygenated hydrocarbons that bear one or more hydroxyl groups comprise a large set of natural and synthetic compounds, often with potent biological activity. In synthetic chemistry, alcohols are important precursors to carbonyl groups, which then can be converted into a wide range of oxygen- or nitrogen based functionality. Therefore, the selective conversion of a single hydroxyl group in natural products into a ketone would enable the selective introduction of unnatural functionality. However, the methods known to convert a simple alcohol, or even an alcohol in a molecule that contains multiple protected functional groups, are not suitable for selective reactions of complex polyol structures. We present a new ruthenium catalyst with a unique efficacy for the selective oxidation of a single hydroxyl group among many in unprotected polyol natural products. This oxidation enables the introduction of nitrogen-based functional groups into such structures that lack nitrogen atoms and enables a selective alcohol epimerization by stepwise or reversible oxidation and reduction. PMID- 29168494 TI - Vibronically coherent ultrafast triplet-pair formation and subsequent thermally activated dissociation control efficient endothermic singlet fission. AB - Singlet exciton fission (SF), the conversion of one spin-singlet exciton (S1) into two spin-triplet excitons (T1), could provide a means to overcome the Shockley-Queisser limit in photovoltaics. SF as measured by the decay of S1 has been shown to occur efficiently and independently of temperature, even when the energy of S1 is as much as 200 meV less than that of 2T1. Here we study films of triisopropylsilyltetracene using transient optical spectroscopy and show that the triplet pair state (TT), which has been proposed to mediate singlet fission, forms on ultrafast timescales (in 300 fs) and that its formation is mediated by the strong coupling of electronic and vibrational degrees of freedom. This is followed by a slower loss of singlet character as the excitation evolves to become only TT. We observe the TT to be thermally dissociated on 10-100 ns timescales to form free triplets. This provides a model for 'temperature independent' efficient TT formation and thermally activated TT separation. PMID- 29168495 TI - A unifying paradigm for naphthoquinone-based meroterpenoid (bio)synthesis. AB - Bacterial meroterpenoids constitute an important class of natural products with diverse biological properties and therapeutic potential. The biosynthetic logic for their production is unknown and defies explanation via classical biochemical paradigms. A large subgroup of naphthoquinone-based meroterpenoids exhibits a substitution pattern of the polyketide-derived aromatic core that seemingly contradicts the established reactivity pattern of polyketide phenol nucleophiles and terpene diphosphate electrophiles. We report the discovery of a hitherto unprecedented enzyme-promoted alpha-hydroxyketone rearrangement catalysed by vanadium-dependent haloperoxidases to account for these discrepancies in the merochlorin and napyradiomycin class of meroterpenoid antibiotics, and we demonstrate that the alpha-hydroxyketone rearrangement is potentially a conserved biosynthetic reaction in this molecular class. The biosynthetic alpha hydroxyketone rearrangement was applied in a concise total synthesis of naphthomevalin, a prominent member of the napyradiomycin meroterpenes, and sheds further light on the mechanism of this unifying enzymatic transformation.

AB - Protein catalysis requires the atomic-level orchestration of side chains, substrates and cofactors, and yet the ability to design a small-molecule-binding protein entirely from first principles with a precisely predetermined structure has not been demonstrated. Here we report the design of a novel protein, PS1, that binds a highly electron-deficient non-natural porphyrin at temperatures up to 100 degrees C. The high-resolution structure of holo-PS1 is in sub-A agreement with the design. The structure of apo-PS1 retains the remote core packing of the holoprotein, with a flexible binding region that is predisposed to ligand binding with the desired geometry. Our results illustrate the unification of core packing and binding-site definition as a central principle of ligand binding protein design. PMID- 29168498 TI - Enantioselective cyclizations and cyclization cascades of samarium ketyl radicals. AB - The rapid generation of molecular complexity from simple starting materials is a key challenge in synthesis. Enantioselective radical cyclization cascades have the potential to deliver complex, densely packed, polycyclic architectures, with control of three-dimensional shape, in one step. Unfortunately, carrying out reactions with radicals in an enantiocontrolled fashion remains challenging due to their high reactivity. This is particularly the case for reactions of radicals generated using the classical reagent, SmI2. Here, we demonstrate that enantioselective SmI2-mediated radical cyclizations and cascades that exploit a simple, recyclable chiral ligand can convert symmetrical ketoesters to complex carbocyclic products bearing multiple stereocentres with high enantio- and diastereocontrol. A computational study has been used to probe the origin of the enantioselectivity. Our studies suggest that many processes that rely on SmI2 can be rendered enantioselective by the design of suitable ligands. PMID- 29168499 TI - Polymer mechanochemistry: Up another rung.

PMID- 29168500 TI - A lysosomal switch triggers proteostasis renewal in the immortal C. elegans germ lineage. AB - Although individuals age and die with time, an animal species can continue indefinitely, because of its immortal germ-cell lineage. How the germline avoids transmitting damage from one generation to the next remains a fundamental question in biology. Here we identify a lysosomal switch that enhances germline proteostasis before fertilization. We find that Caenorhabditis elegans oocytes whose maturation is arrested by the absence of sperm exhibit hallmarks of proteostasis collapse, including protein aggregation. Remarkably, sperm-secreted hormones re-establish oocyte proteostasis once fertilization becomes imminent. Key to this restoration is activation of the vacuolar H+-ATPase (V-ATPase), a proton pump that acidifies lysosomes. Sperm stimulate V-ATPase activity in oocytes by signalling the degradation of GLD-1, a translational repressor that blocks V-ATPase synthesis. Activated lysosomes, in turn, promote a metabolic shift that mobilizes protein aggregates for degradation, and reset proteostasis by enveloping and clearing the aggregates. Lysosome acidification also occurs during Xenopus oocyte maturation; thus, a lysosomal switch that enhances oocyte proteostasis in anticipation of fertilization may be conserved in other species. PMID- 29168502 TI - A gut bacterial pathway metabolizes aromatic amino acids into nine circulating metabolites. AB - The human gut microbiota produces dozens of metabolites that accumulate in the bloodstream, where they can have systemic effects on the host. Although these small molecules commonly reach concentrations similar to those achieved by pharmaceutical agents, remarkably little is known about the microbial metabolic pathways that produce them. Here we use a combination of genetics and metabolic profiling to characterize a pathway from the gut symbiont Clostridium sporogenes that generates aromatic amino acid metabolites. Our results reveal that this pathway produces twelve compounds, nine of which are known to accumulate in host serum. All three aromatic amino acids (tryptophan, phenylalanine and tyrosine) serve as substrates for the pathway, and it involves branching and alternative reductases for specific intermediates. By genetically manipulating C. sporogenes, we modulate serum levels of these metabolites in gnotobiotic mice, and show that in turn this affects intestinal permeability and systemic immunity. This work has the potential to provide the basis of a systematic effort to engineer the molecular output of the gut bacterial community. PMID- 29168505 TI - Corrigendum: The 4D nucleome project.

AB - Small, approximately 10-kilobase microhomology-mediated tandem duplications are abundant in the genomes of BRCA1-linked but not BRCA2-linked breast cancer. Here we define the mechanism underlying this rearrangement signature. We show that, in primary mammalian cells, BRCA1, but not BRCA2, suppresses the formation of tandem duplications at a site-specific chromosomal replication fork barrier imposed by the binding of Tus proteins to an array of Ter sites. BRCA1 has no equivalent role at chromosomal double-stranded DNA breaks, indicating that tandem duplications form specifically at stalled forks. Tandem duplications in BRCA1 mutant cells arise by a replication restart-bypass mechanism terminated by end joining or by microhomology-mediated template switching, the latter forming complex tandem duplication breakpoints. Solitary DNA ends form directly at Tus Ter, implicating misrepair of these lesions in tandem duplication formation. Furthermore, BRCA1 inactivation is strongly associated with ~10 kilobase tandem duplications in ovarian cancer. This tandem duplicator phenotype may be a general signature of BRCA1-deficient cancer. PMID- 29168506 TI - NFS1 undergoes positive selection in lung tumours and protects cells from ferroptosis. AB - Environmental nutrient levels impact cancer cell metabolism, resulting in context dependent gene essentiality. Here, using loss-of-function screening based on RNA interference, we show that environmental oxygen levels are a major driver of differential essentiality between in vitro model systems and in vivo tumours. Above the 3-8% oxygen concentration typical of most tissues, we find that cancer cells depend on high levels of the iron-sulfur cluster biosynthetic enzyme NFS1. Mammary or subcutaneous tumours grow despite suppression of NFS1, whereas metastatic or primary lung tumours do not. Consistent with a role in surviving the high oxygen environment of incipient lung tumours, NFS1 lies in a region of genomic amplification present in lung adenocarcinoma and is most highly expressed in well-differentiated adenocarcinomas. NFS1 activity is particularly important for maintaining the iron-sulfur co-factors present in multiple cell-essential proteins upon exposure to oxygen compared to other forms of oxidative damage. Furthermore, insufficient iron-sulfur cluster maintenance robustly activates the iron-starvation response and, in combination with inhibition of glutathione biosynthesis, triggers ferroptosis, a non-apoptotic form of cell death. Suppression of NFS1 cooperates with inhibition of cysteine transport to trigger ferroptosis in vitro and slow tumour growth. Therefore, lung adenocarcinomas select for expression of a pathway that confers resistance to high oxygen tension and protects cells from undergoing ferroptosis in response to oxidative damage. PMID- 29168507 TI - Orthogonal muscle fibres have different instructive roles in planarian regeneration. AB - The ability to regenerate missing body parts exists throughout the animal kingdom. Positional information is crucial for regeneration, but how it is harboured and used by differentiated tissues is poorly understood. In planarians, positional information has been identified from study of phenotypes caused by RNA interference in which the wrong tissues are regenerated. For example, inhibition of the Wnt signalling pathway leads to regeneration of heads in place of tails. Characterization of these phenotypes has led to the identification of position control genes (PCGs)-genes that are expressed in a constitutive and regional manner and are associated with patterning. Most PCGs are expressed within planarian muscle; however, how muscle is specified and how different muscle subsets affect regeneration is unknown. Here we show that different muscle fibres have distinct regulatory roles during regeneration in the planarian Schmidtea mediterranea. myoD is required for formation of a specific muscle cell subset: the longitudinal fibres, oriented along the anterior-posterior axis. Loss of longitudinal fibres led to complete regeneration failure because of defects in regeneration initiation. A different transcription factor-encoding gene, nkx1-1, is required for the formation of circular fibres, oriented along the medial lateral axis. Loss of circular fibres led to a bifurcated anterior-posterior axis with fused heads forming in single anterior blastemas. Whereas muscle is often viewed as a strictly contractile tissue, these findings reveal that different muscle types have distinct and specific regulatory roles in wound signalling and patterning to enable regeneration.

PMID- 29168510 TI - A laboratory heterodyne emission spectrometer at submillimeter wavelengths. AB - We present first results on a newly built broadband emission spectrometer for the laboratory making use of a double sideband (DSB) heterodyne receiver. The new spectrometer is perfectly suited for high-resolution emission spectroscopy of molecules of astrophysical importance. The current SIS receiver operates at RF frequencies between 270 and 390 GHz, coincident with Band 7 of the ALMA telescope. The instantaneous bandwidth is 5 GHz (DSB). In this work the full spectrometer and its components are described. Its performance, in particular its sensitivity, stability, reproducibility and systematic errors, is characterized in detail. For this purpose very broad band emission spectra of methyl cyanide have been recorded and compared to theoretical spectra. Isotopic variants are found in natural abundance and features attributed to vibrationally excited species are all recorded in the same spectrum. The performance of the new spectrometer is compared extensively to that of a traditional FM-absorption spectrometer and to recent versions of chirped-pulse spectrometers operated in the mm-wave regime. Further applications and future advancements of the current instrument are discussed. PMID- 29168508 TI - Structural basis for the initiation of eukaryotic transcription-coupled DNA repair. AB - Eukaryotic transcription-coupled repair (TCR) is an important and well-conserved sub-pathway of nucleotide excision repair that preferentially removes DNA lesions from the template strand that block translocation of RNA polymerase II (Pol II). Cockayne syndrome group B (CSB, also known as ERCC6) protein in humans (or its yeast orthologues, Rad26 in Saccharomyces cerevisiae and Rhp26 in Schizosaccharomyces pombe) is among the first proteins to be recruited to the lesion-arrested Pol II during the initiation of eukaryotic TCR. Mutations in CSB are associated with the autosomal-recessive neurological disorder Cockayne syndrome, which is characterized by progeriod features, growth failure and photosensitivity. The molecular mechanism of eukaryotic TCR initiation remains unclear, with several long-standing unanswered questions. How cells distinguish DNA lesion-arrested Pol II from other forms of arrested Pol II, the role of CSB in TCR initiation, and how CSB interacts with the arrested Pol II complex are all unknown. The lack of structures of CSB or the Pol II-CSB complex has hindered our ability to address these questions. Here we report the structure of the S. cerevisiae Pol II-Rad26 complex solved by cryo-electron microscopy. The structure reveals that Rad26 binds to the DNA upstream of Pol II, where it markedly alters its path. Our structural and functional data suggest that the conserved Swi2/Snf2 family core ATPase domain promotes the forward movement of Pol II, and elucidate key roles for Rad26 in both TCR and transcription elongation.

AB - This paper reports the solvent extraction of Am3+ and Eu3+ using N,N,N',N',N'',N''-hexa-n-octylnitrilotriacetamide (HONTA) as the extractant in n dodecane. The results are in variance with those reported previously with respect to the nature of the extracted species. The solvent extraction data were entirely different from those reported previously as the extracted species conformed to 1 : 2 (M : L) species for both Am3+ and Eu3+ ions. The structure of the extracted complex was determined by EXAFS demonstrating the three amidic 'O' atoms of the HONTA complex with the Eu3+ ion. In the case of the Am3+ ion, the pivotal 'N' atom is suggested to bond to the metal ion, which may explain the significantly more favourable extraction of Am3+vis-a-vis Eu3+. The absence of H2O molecules in the inner coordination sphere of the Eu3+-HONTA extract was confirmed by luminescence spectroscopic measurements. Complexation studies in MeOH and EtOH indicated the formation of both 1 : 1 and 1 : 2 complexes with Nd3+ ions. The results are explained on the basis of DFT calculations using HMNTA, the corresponding hexamethyl analogue of HONTA. PMID- 29168503 TI - Measurement of the multi-TeV neutrino interaction cross-section with IceCube using Earth absorption. AB - Neutrinos interact only very weakly, so they are extremely penetrating. The theoretical neutrino-nucleon interaction cross-section, however, increases with increasing neutrino energy, and neutrinos with energies above 40 teraelectronvolts (TeV) are expected to be absorbed as they pass through the Earth. Experimentally, the cross-section has been determined only at the relatively low energies (below 0.4 TeV) that are available at neutrino beams from accelerators. Here we report a measurement of neutrino absorption by the Earth using a sample of 10,784 energetic upward-going neutrino-induced muons. The flux of high-energy neutrinos transiting long paths through the Earth is attenuated compared to a reference sample that follows shorter trajectories. Using a fit to the two-dimensional distribution of muon energy and zenith angle, we determine the neutrino-nucleon interaction cross-section for neutrino energies 6.3-980 TeV, more than an order of magnitude higher than previous measurements. The measured cross-section is about 1.3 times the prediction of the standard model, consistent with the expectations for charged- and neutral-current interactions. We do not observe a large increase in the cross-section with neutrino energy, in contrast with the predictions of some theoretical models, including those invoking more compact spatial dimensions or the production of leptoquarks. This cross-section measurement can be used to set limits on the existence of some hypothesized beyond-standard-model particles, including leptoquarks.

AB - Reaction of 2-bromo-1,3,2-diazaborole (1) with excess BBr3 induces 1,2-hydrogen migration, giving 1,3,2-diazaborole-derived carbene complexes of boron bromide (2). Compound 2 exists in a dynamic solution equilibrium with 1. The 1H NMR study shows that the equilibrium lies to the right side of the dissociation reaction of 2. Parallel reaction of 1 with excess BI3 gives the corresponding 1,3,2 diazaborole-derived carbene boron iodide complex (3). Notably, in contrast to 2, the dissociation reaction of 3 largely lies to the left side, favouring the formation of 3. The dynamic solution equilibrium behaviours of 2 and 3 are probed by both experimental and theoretical methods. PMID- 29168514 TI - Specific protein supplementation using soya, casein or whey differentially affects regional gut growth and luminal growth factor bioactivity in rats; implications for the treatment of gut injury and stimulating repair. AB - Modulation of regional growth within specific segments of the bowel may have clinical value for several gastrointestinal conditions. We therefore examined the effects of different dietary protein sources on regional gut growth and luminal growth factor bioactivity as potential therapies. Rats were fed for 14 days on isonitrogenous and isocaloric diets comprising elemental diet (ED) alone (which is known to cause gut atrophy), ED supplemented with casein or whey or a soya protein-rich feed. Effects on regional gut growth and intraluminal growth factor activity were then determined. Despite calorie intake being similar in all groups, soya rich feed caused 20% extra total body weight gain. Stomach weight was highest on soya and casein diets. Soya enhanced diet caused greatest increase in small intestinal weight and preserved luminal growth factor activity at levels sufficient to increase proliferation in vitro. Regional small intestinal proliferation was highest in proximal segment in ED fed animals whereas distal small intestine proliferation was greater in soya fed animals. Colonic weight and proliferation throughout the colon was higher in animals receiving soya or whey supplemented feeds. We conclude that specific protein supplementation with either soya, casein or whey may be beneficial to rest or increase growth in different regions of the bowel through mechanisms that include differentially affecting luminal growth factor bioactivity. These results have implications for targeting specific regions of the bowel for conditions such as Crohn's disease and chemotherapy. PMID- 29168517 TI - Crossed beam polyatomic reaction dynamics: recent advances and new insights. AB - Over the past ten years or so, great advances in our understanding of the dynamics of elementary (bimolecular) polyatomic reactions in the gas-phase have occurred. This has been made possible by critical improvements (a) in crossed molecular beam (CMB) instruments with rotating mass spectrometric detection and time-of-flight analysis, especially following the implementation of soft ionization (by tunable low energy electrons or vacuum-ultraviolet synchrotron radiation) for product detection with increased sensitivity and universal detection power, and (b) in REMPI-slice velocity map ion imaging (VMI) detection techniques in pulsed CMB experiments for obtaining product pair-correlated information through high-resolution measurements directly in the center of mass system. The improved universal CMB method is permitting us to identify all primary reaction products, characterize their formation dynamics, and determine the branching ratios (BRs) for multichannel non-adiabatic reactions, such as those of ground state oxygen atoms, O(3P), with unsaturated hydrocarbons (alkynes, alkenes, dienes). The improved slice VMI CMB technique is permitting us to explore at an unprecedented level of detail, through pair-correlated measurements, the reaction dynamics of a prototype polyatomic molecule such as CH4 (and isotopologues) in its ground state with a variety of important X radicals such as F, Cl, O, and OH. In this review, we highlight this recent progress in the field of CMB reaction dynamics, with an emphasis on the experimental side, but with the related theoretical work, at the level of state of-the-art calculations of both the underlying potential energy surfaces and the reaction dynamics, noted throughout. In particular, the focus is (a) on the effect of molecular complexity and structure on product distributions, branching ratios and role of intersystem crossing for the multichannel, addition elimination reactions of unsaturated hydrocarbons with O atoms, and (b) on the very detailed dynamics of the abstraction reactions of ground-state methane (and isotopologues) with atoms (F, Cl, O) and diatoms (OH), with inclusion of also rotational mode specificity in the vibrationally excited methane reactions. PMID- 29168516 TI - Computational screening of functional groups for capture of toxic industrial chemicals in porous materials. AB - A thermodynamic analysis using quantum chemical methods was carried out to identify optimal functional group candidates that can be included in metal organic frameworks and activated carbons for the selective capture of toxic industrial chemicals (TICs) in humid air. We calculated the binding energies of 14 critical TICs plus water with a series of 10 functional groups attached to a naphthalene ring model. Using vibrational calculations, the free energies of adsorption were calculated in addition to the binding energies. Our results show that, in these systems, the binding energies and free energies follow similar trends. We identified copper(i) carboxylate as the optimal functional group (among those studied) for the selective binding of the majority of the TICs in humid air, and this functional group exhibits especially strong binding for sulfuric acid. Further thermodynamic analysis shows that the presence of water weakens the binding strength of sulfuric acid with the copper carboxylate group. Our calculations predict that functionalization of aromatic rings would be detrimental to selective capture of COCl2, CO2, and Cl2 under humid conditions. Finally, we found that forming an ionic complex, H3O+HSO4-, between H2SO4 and H2O via proton transfer is not favorable on copper carboxylate.

AB - Based on the careful design of two-terminal devices from multi-layer transition metal dichalcogenides (TMDs) such as MoS2 and WSe2, truly vertical transport has been experimentally evaluated and theoretically analyzed. By exploring, the electric field and temperature dependence of in total 28 TMD devices of various thicknesses, a model that describes vertical transport as Fowler Nordheim mediated at high electric fields and thermal injection dominated at low fields has been developed. Our approach is similar to the description chosen to capture gate leakage current levels through amorphous materials such as SiO2. Employing our quantitative analysis, an effective vertical transport mass of m*/m0 (MoS2) ~ 0.18 and m*/m0 (WSe2) ~ 0.14 has been extracted for the first time and barriers at the metal contact-to-TMD interface of heights similar to those extracted for lateral transport in TMD transistors have been confirmed.

AB - Carbon vacancies are commonly present in two-dimensional (2D) MXenes that hold promise in a variety of applications whereas their behavior remains unknown. Here we report on the influence of carbon vacancies on the structural stability, electronic properties and stiffness of MXenes by taking Ti2CT2 (T = O, F, and OH) as an example. According to the first-principles calculations, the formation energies of carbon vacancies in MXenes are lower than those in other typical 2D materials including graphene and MoS2, in combination with high migration energies. These two features mean that carbon-vacant MXenes are thermodynamically and dynamically stable as further evidenced by the absence of structural reconstruction both in the ground state and at ambient temperature. Interestingly, carbon vacancies that are usually considered as defects substantially offer a new opportunity on at least two aspects: enhanced electronic conduction and reduced stiffness corresponding to improved flexibility. The localized states in the vicinity of the Fermi level introduced by carbon vacancies account for the prominent metallic characteristics in carbon vacant Ti2CT2 MXenes.

Furthermore, from the mononuclear Nb complexes (1a or 4a), a new structural form of tetrameric niobium complexes (8a and 9a) was synthesized through a controlled hydrolysis reaction. The molecular structures of complexes 1b, 4b, 7a, 8a and 9a were unambiguously confirmed by single crystal X-ray diffraction analyses. Furthermore, all these complexes (1a-9a and 1b-6b) were tested as catalysts for the ring-opening polymerisation (ROP) of glycidol to synthesize hyperbranched polyglycerols (HPG) by using 1,1,1 tris(hydroxymethyl)propane (TMP) as an initiator. The degree of branching (DB) observed was 0.30-0.54, which is an indication of hyperbranched structures. In particular, for the niobium complex with electron-withdrawing substituents on the benzoxazole phenoxide pro-ligand (5a), we achieved superior behavior for the ROP of glycidol in terms of activity, control of molecular weight (Mn) and molecular weight distributions (MWDs) (92% of glycidol to HPG, Mn = 10.52 kg mol-1, MWDs <1.33, DB = 0.53 and Tg = -57 degrees C). A highly hydrophilic nature was observed for the synthesized HPG polymer by water contact angle measurement (20 degrees to 35 degrees ).

AB - This paper is aimed at demonstrating the potentiality of high resolution Attenuated Total Reflection Fourier Transform Infrared micro-mapping (micro-ATR FTIR) to reconstruct the images of micrometric multi-layered systems. This method can be an effective analytical alternative when the layer thickness requires high lateral resolution, and fluorescence or thermal effects prevent the deployment of conventional analytical techniques such as micro-Raman spectroscopy. This study demonstrates the high micro-ATR-FTIR setup performances in terms of lateral resolution, spectral quality and chemical image contrast using a new laboratory instrument equipped with a single element detector. The method has been first validated on mock-ups and then successfully applied on cross-sectional samples from real artworks: Leonardo da Vinci's mural painting, characterised by a few micrometers thin sequence of organic and inorganic layers, and an outdoor marble statue, with a complex sequence of decay products on its surface. This study paves the way to a new investigation modality of micrometric systems, combining high lateral resolution with excellent spectral quality, essential in the field of Cultural Heritage as well as in the wider area of materials and forensic sciences. PMID- 29168523 TI - Electroconductive nanoscale topography for enhanced neuronal differentiation and electrophysiological maturation of human neural stem cells. AB - Biophysical cues, such as topography, and electrical cues can provide external stimulation for the promotion of stem cell neurogenesis. Here, we demonstrate an electroconductive surface nanotopography for enhancing neuronal differentiation and the functional maturation of human neural stem cells (hNSCs). The electroconductive nanopatterned substrates were prepared by depositing a thin layer of titanium (Ti) with nanograting topographies (150 to 300 nm groove/ridge, the thickness of the groove - 150 MUm) onto polymer surfaces. The Ti-coated nanopatterned substrate (TNS) induced cellular alignment along the groove pattern via contact guidance and promoted focal adhesion and cytoskeletal reorganization, which ultimately led to enhanced neuronal differentiation and maturation of hNSCs as indicated by significantly elevated neurite extension and the upregulated expression of the neuronal markers Tuj1 and NeuN compared with the Ti-coated flat substrate (TFS) and the nanopatterned substrate (NS) without Ti coating. Mechanosensitive cellular events, such as beta1-integrin binding/clustering and myosin-actin interaction, and the Rho-associated protein kinase (ROCK) and mitogen-activated protein kinase/extracellular signal regulated kinase (MEK-ERK) pathways, were found to be associated with enhanced focal adhesion and neuronal differentiation of hNSCs by the TNS. Among the neuronal subtypes, differentiation into dopaminergic and glutamatergic neurons was promoted on the TNS. Importantly, the TNS increased the induction rate of neuron-like cells exhibiting electrophysiological properties from hNSCs. Finally, the application of pulsed electrical stimulation to the TNS further enhanced neuronal differentiation of hNSCs due probably to calcium channel activation, indicating a combined effect of topographical and electrical cues on stem cell neurogenesis, which postulates the novelty of our current study. The present work suggests that an electroconductive nanopatterned substrate can serve as an effective culture platform for deriving highly mature, functional neuronal lineage cells from stem cells. PMID- 29168524 TI - Confined naked gold nanoparticles in ionic liquid films. AB - Surface-clean Au nanoparticles (NPs) confined in films of ionic liquids (ILs) can be easily fabricated by sputtering deposition. A silicon wafer coated with films of both hydrophobic (bis((trifluoromethyl)sulfonyl)amide, NTf2-) and hydrophilic (tetrafluoroborate, BF4-) imidazolium-based ILs forms an 'ionic carpet-like' structure that can be easily decorated with Au NPs of 5.1 and 6.5 nm mean diameter, respectively. The depth profile distribution of the Au NPs depends on the arrangement of the IL, which is controlled mainly by the anion volume. Higher concentrations of Au NPs are found closer to the IL surface for the system containing a larger anion (NTf2) whereas Au NPs are located deeper in the IL for the system containing a smaller anion (BF4). The Au NPs are well distributed over the IL/Si support and are strictly confined in a single layer of the IL. This method is among the most simple and versatile for the generation of liquid layers containing surface-clean, stable and confined Au NPs. PMID- 29168525 TI - MXene: a potential candidate for yarn supercapacitors. AB - The increasing developments in wearable electronics demand compatible power sources such as yarn supercapacitors (YSCs) that can effectively perform in a limited footprint. MXene nanosheets, which have been recently shown in the literature to possess ultra-high volumetric capacitance, were used in this study for the fabrication of YSCs in order to identify their potential merit and performance in YSCs. With the aid of a conductive binder (PEDOT-PSS), YSCs with high mass loading of MXene are demonstrated. These MXene-based YSCs exhibit excellent device performance and stability even under bending and twisting. This study demonstrates that MXene is a promising candidate for YSCs and its further development can lead to flexible power sources with sufficient performance for powering miniaturized and/or wearable electronics. PMID- 29168526 TI - How the toxicity of nanomaterials towards different species could be simultaneously evaluated: a novel multi-nano-read-across approach. AB - Application of predictive modeling approaches can solve the problem of missing data. Numerous studies have investigated the effects of missing values on qualitative or quantitative modeling, but only a few studies have discussed it for the case of applications in nanotechnology-related data. The present study is aimed at the development of a multi-nano-read-across modeling technique that helps in predicting the toxicity of different species such as bacteria, algae, protozoa, and mammalian cell lines. Herein, the experimental toxicity of 184 metal and silica oxide (30 unique chemical types) nanoparticles from 15 datasets is analyzed. A hybrid quantitative multi-nano-read-across approach that combines interspecies correlation analysis and self-organizing map analysis is developed. In the first step, hidden patterns of toxicity among nanoparticles are identified using a combination of methods. Subsequently, the developed model based on categorization of the toxicity of the metal oxide nanoparticle outcomes is evaluated via the combination of supervised and unsupervised machine learning techniques to determine the underlying factors responsible for the toxicity.

AB - A facile domino reaction of 2-chloroquinoline-3-carbaldehydes in one and two equivalents of isocyanide has been investigated. Three-component reactions of 2 chloroquinoline-3-carbaldehydes, isocyanides and amines are also described. In this Pd-catalyzed reaction under controlled conditions, three novel types of quinoline derivatives were formed via amidation, lactamization or carbamate formation along with the formation of C-C, C-N, and C-O bonds in a one-pot procedure. PMID- 29168532 TI - Complete tetraglycosylation of a calix[4]arene by a chemo-enzymatic approach. AB - Polyglycosylated calixarenes are efficient and selective multivalent ligands for lectins. However, the chemical decoration of these macrocyclic scaffolds with saccharides of increasing complexity is hampered by the highly complex chemistry of carbohydrates. An alternative to the conventional approach is the enzymatic diversification of simple glycocluster-presented glycans. In this work, we present a highly efficient chemo-enzymatic approach to tetra-N-acetyl lactosaminylcalix[4]arene via glycan extension catalyzed by a human beta-1,4 galactosyltransferase. This demonstrates that calixarenes can be exhaustively processed by enzymatic glycosyl transfer despite the heavy steric crowding, paving the way to the design and achievement of multivalent ligands based on these macrocyclic scaffolds having complex branched glycans. PMID- 29168533 TI - Unprecedented carbon sub-microspheres with a porous hierarchy for highly efficient oxygen electrochemistry. AB - Developing efficient and robust electrocatalysts for bifunctional oxygen electrocatalysis is crucial for renewable energy technology. Herein, nitrogen and phosphorus co-doped carbon sub-microspheres with fascinating mesostructures are rationally synthesized through an effective soft-templating strategy. The unique features of substantial doping, large surface areas and well-defined porosity endow the dual-doped carbons with high-density electroactive sites, considerable active surface areas and improved mass transfer, ensuring impressive activity and durability in catalyzing oxygen reduction and evolution reactions, even competing with the noble metal benchmarks, thus assuring their use as an air cathode in a rechargeable Zn-air battery with low charge-discharge overpotential and remarkable long-term stability. PMID- 29168534 TI - Zero-dimensional methylammonium iodo bismuthate solar cells and synergistic interactions with silicon nanocrystals. AB - Organometal trihalide perovskite solar cells have attracted monumental attention in recent years. Today's best devices, based on a three-dimensional perovskite structure of corner-sharing PbI6 octahedra, are unstable, toxic, and display hysteresis in current-voltage measurements. We present zero-dimensional organic inorganic hybrid solar cells based on methylammonium iodo bismuthate (CH3NH3)3(Bi2I9) (MABI) comprising a Bi2I9 bioctahedra and observe very low hysteresis for scan rates in the broad range of 150 mV s-1 to 1500 mV s-1 without any interfacial layer engineering. We confirm good stability for devices produced and stored in open air without humidity control. The MABI structure can also accommodate silicon nanocrystals, leading to an enhancement in the short-circuit current. Through the material MABI, we demonstrate a promising alternative to the organometal trihalide perovskite class and present a model material for future composite third-generation photovoltaics. PMID- 29168535 TI - Highly reliable and low-noise solid-state nanopores with an atomic layer deposited ZnO membrane on a quartz substrate. AB - We present a fabrication scheme for a solid-state ZnO nanopore membrane directly deposited on top of a quartz substrate by atomic layer deposition (ALD) and investigate the characteristics of DNA translocation through the nanopores. We chose a ZnO membrane owing to its high isoelectric point (~9.5) as well as its chemical and mechanical stability. Aside from the extremely low noise level exhibited by this device on a highly insulating and low dielectric quartz substrate, it also slows down the translocation speed of DNA by more than one order of magnitude as compared to that of a SiNx nanopore device. We propose that the electrostatic interaction between the positively charged ZnO nanopore wall, resulting from the high isoelectric point of ZnO, and the negatively charged phosphate backbone of DNA provides an additional frictional force that slows down the DNA translocation.

AB - Functionalized polycyclic pyrrole-azole structures possessing fused six membered and seven membered rings were directly synthesized via ligand-enabled, Pd catalyzed, site selective, intramolecular cross couplings of N-substituted pyrrole-azoles. C5-H activation in the presence of a reactive C2-H remains a challenge that needs to be addressed and this was targeted to be resolved through the present approach by specifically generating the cyclized products with 83 100% selectivity. The featured methodology provides a novel disconnection for the synthesis of pyrrole containing alkaloids and medicinal compounds. PMID- 29168538 TI - Anxiety disorders and stressful events in Takotsubo syndrome. AB - BACKGROUND: Anxiety disorders are more common in Takotsubo syndrome (TS) than in acute coronary syndrome patients. The aim of this study was to investigate whether pre-existing anxiety disorders predispose to TS triggered by exclusively emotional stressful events. METHODS: Triggering events were compared in 58 TS patients with and without pre-existing anxiety disorders; clinical, electrocardiographic and echocardiographic data were also collected. RESULTS: Thirty-one (53%) patients had a previous history of anxiety disorders. The exclusively emotional stressful event-rate was higher in TS patients with pre existing anxiety disorder (74% vs. 30%, p = 0.001), while TS caused by an undetermined trigger were significantly higher in patients without anxiety disorders (33% vs. 10%, p = 0.027). Moreover, in TS patients without a previous history of anxiety disorders, a trend of higher prevalence of physical events was found (16% vs. 37%, p = 0.07). CONCLUSIONS: In patients with pre-existing anxiety disorders, TS was predominantly triggered by exclusively emotional stressful events, thereby suggesting a possible relationship between anxiety and emotional cardiac frailty in TS patients. PMID- 29168539 TI - Severe degenerative aortic stenosis with preserved ejection fraction does not change adipokines serum levels. AB - BACKGROUND: The role of the adipokines in the pathogenesis of aortic stenosis (AS) is not well established. The aim was to evaluate the relationship between adipokines and clinical characteristics as well as echocardiographic indices and noninvasive markers of vascular remodeling in patients with severe AS with preserved ejection fraction (EF). METHODS: Sixty-five patients (F/M: 38/27; age: 68.3 +/- 9.0 years; body mass index [BMI]: 29.6 +/- 4.3 kg/m2) with severe AS with preserved EF: 33 patients with paradoxical low-flow low-gradient AS (PLFLG AS) and 32 patients with normal flow high-gradient AS (NFHG AS) were prospectively enrolled into the study. Twenty-four subjects (F/M: 14/10; age: 65.4 +/- 8.7 years; BMI: 29.6 +/- 4.3 kg/m2) who matched as to age, sex, BMI and coronary artery disease (CAD) constituted the control group (CG). Clinical data and markers of vascular remodeling were related to the serum adipokines. RESULTS: There were no differences in the adipokines concentrations in the AS/CG. Patients with AS and coexisting CAD were characterized by decreased serum adiponectin (9.9 +/- 5.5 vs. 12.7 +/- 5.8 MUg/mL, p = 0.040) and leptin (8.3 +/- 7.8 vs. 21.6 +/- 17.1 ng/mL, p < 0.001) levels compared to subjects without CAD. There were no differences in the serum adipokines concentrations between patients with PLFLG AS and NFHG AS. Systemic hypertension, diabetes, hyperlipidemia or markers of vascular remodeling did not discriminate adipokines concentrations. Multivariate regression analysis indicated that age (F = 3.02; p = 0.015) and E/E' index (F = 0.87, p = 0.032) were independent predictors of the adiponectin level in the AS group. CONCLUSIONS: The presence of AS with preserved EF did not change the adipokine serum profile. Adipokines levels were modified by coexisting atherosclerosis but not the typical cardiovascular risk factors or the hemodynamic type of AS. PMID- 29168540 TI - Identification of a peripheral blood long non-coding RNA (Upperhand) as a potential diagnostic marker of coronary artery disease. AB - BACKGROUND: Long non-coding RNAs (lncRNAs) have been confirmed to be involved in the pathologi-cal processes of multiple diseases. However, the characteristic expression of lncRNAs in peripheral blood of coronary artery disease (CAD) patients and whether some of these lncRNAs can be used as diagnostic biomarkers for CAD requires further investigation. METHODS: Six healthy and CAD individuals were selected for microarray analysis, and 5 differentially expressed lncRNAs were selected and confirmed in the second cohort consisting of 30 control individu-als and 30 CAD patients with different SYNTAX scores. Upperhand were verified in the third cohort consisting of 115 controls and 137 CAD patients. RESULTS: Thirty one lncRNAs were differentially expressed between the two groups, among whom, 25 were upregulated in the CAD group and 6 were downregulated. Four of the selected five lncRNAs were significantly upregulated in the CAD group, and Upperhand had the largest area under the curve (AUC). The diagnostic value of Upperhand was tested further, and it remained having a high diagnostic value. CONCLUSIONS: The expression level of Upperhand in peripheral blood of CAD patients is significantly higher than in control individuals, and is correlated with severity of CAD. Upperhand is a potential diagnostic biomarker of CAD, and when combined with TCONS_00029157, diagnostic value slightly increased. PMID- 29168541 TI - Evaluation of bioresorbable vascular scaffolds in acute coronary syndrome: A two center, one-year follow-up analysis. AB - BACKGROUND: Bioresorbable vascular scaffolds (BVS) have emerged as a new treatment option in cardiovascular medicine. Nonetheless, there is still limited data on the use of these novel devices in patients with acute coronary syndromes (ACS). The purpose of this study was to evaluate the feasibility and efficacy of BVS implantation in patients with ACS. METHODS: The present report is a prospective, two-center registry that involved 165 consecutive patients hospitalized with the diagnosis of ACS and treated with the Absorb BVS (Abbot Vascular, Santa Clara, USA). During 1-year, all patients were monitored for the following endpoints: death, myocardial infarction (MI), scaffold thrombosis (ST), target lesion revascularization (TLR), target vessel revascularization (TVR) and target vessel failure (TVF), defined as cardiac death, target vessel MI, and TVR. RESULTS: A total of 165 patients underwent 179 BVS implantations. 94 patients were diagnosed with unstable angina (UA; 57.6%), 45 with non-ST-segment elevation myocardial infarction (NSTEMI; 27.3%) and 26 with ST-segment elevation myocardial infarction (STEMI; 15.7%). Procedural success was achieved in all patients with thrombolysis in myocardial infarction flow 3. During a follow-up of 14.1 +/- 8.5 months (median 12.4 months, IQR 8.7 [8.4 to 12.1] months) death occurred in 4 (2.4%) patients, including 2 (1.3%) cardiac deaths. There was only 1 case of subacute ST (0.66%), without late ST. The incidence of MI, TLR, TVR and TVF were: 2.65%, 2.65%, 7.95%, 9.3%, respectively. CONCLUSIONS: The present results suggest that BVS implantation in ACS patients is feasible and safe in highly experienced centers. One-year clinical results are encouraging with a low rate of stent thrombosis. PMID- 29168542 TI - State-of-the-art of transcatheter treatment of aortic valve stenosis and the overview of the InFlow project aiming at developing the first Polish TAVI system. AB - Initial experience of transcatheter aortic valve implantation (TAVI) or replacement (TAVR) has ap-peared as a promising minimally invasive technology for patients disqualified from surgical treatment (SAVR). Safety and efficacy of TAVI has been analyzed and assessed through numerous registries and trials. Furthermore, results obtained from comparative TAVI vs. SAVR trials proved that both treat!ments can be considered equal in terms of post-procedural mortality and morbidity in high-risk, as well as lower risk patients. However, there are still some issues that have to be addressed, such as higher chance of paravalvular leakage, vascular injuries, conduction disturbances, malpositioning and the yet unmet problem of insufficient biological valves durability. Recent technological developments along with the learning curve of operators prove a great potential for improvement of TAVI and a chance of surpassing SAVR in various groups of patients in the near future. In pursuit of finding new solutions, the CardValve Consortium consisting of leading scientific and research institutions in Poland has been created. Under the name of InFlow and financial support from the National Center for Research and Development, they have started a project with the aim to design, create and implement into clinical practice the first, Polish, low-profile TAVI valve system, utilizing not only biological but also artificial, polymeric-based prosthesis. This review focuses on current developments in TAVI technologies including the InFlow project. PMID- 29168543 TI - Lipid-lowering therapy with PCSK9-inhibitors in the management of cardiovascular high-risk patients: Effectiveness, therapy adherence and safety in a real world cohort. AB - BACKGROUND: Proprotein convertase subtilisin/kexin type 9 (PCSK9)-inhibitors have shown great po-tential in efficient lipid lowering to achieve low-density lipoprotein-cholesterol (LDL-C) treatment goals. The aim of the study was too describe the clinical use of PCSK9-inhibitors and to investigate therapy adherence and safety outside of clinical trials. METHODS: Thirty-eight patients were treated with PSCK9-inhibitors. Patients were eligible for this therapy based on their individual cardiovascular risk and when all other available lipid lowering regi-men had failed. Every patient answered a questionnaire concerning medical history and relevant side effects and therapy adherence. RESULTS: Conventional therapy reduced patient LDL-C levels by about 38%. However, in 26 of the 38 patients, LDL-C treatment goals were not fulfilled because patients did not tolerate further dose es-calation due to side effects. Using a PCSK9 inhibitor, LDL-C levels were reduced by another 54% and 42% of patients reaching treatment goals. The results show that most patients still require concomitant therapy to reach LDL-C target levels. Three patients required dose reduction or change of the PCSK9 inhibitor. 16% did not inject the PCSK9 inhibitor regularly. CONCLUSIONS: Only a minority of patients reached the recommended LDL-C goals. PCSK9-inhibitors were generally well tolerated. Despite low rates of reported side effects, therapy adherence was incom-plete, with 6 patients not injecting PCSK9-inhibitors on a regular basis. In-depth information about the medication and close supervision is advisable. PCSK9 inhibitors have shown great potential in aggressive lipid lowering therapy, but basic therapy is still required in most cases. Close supervision is recommended to improve therapy adherence.

PMID- 29168546 TI - Glucocorticoids and beta-cell function. AB - Glucocorticoids (GCs) play a pivotal role in carbohydrate metabolism. They counteract insulin by decreasing peripheral glucose uptake and stimulating hepatic gluconeogenesis, although they are best known for inducing insulin resistance (IR). Moreover, GCs may attenuate the incretin effect. Nevertheless, their direct impact on beta cells is not fully defined. This review aims to present the current understanding of this subject. Humans exposed to GC excess display IR, impaired glucose tolerance, and eventually develop diabetes. Although their insulin levels are elevated, they present lower insulin output in response to glucose than obese individuals. Rodent models demonstrate that GC-induced IR is accompanied by compensatory beta-cell hyperplasia. GC excess with high-fat diet leads to fasting hyperglycaemia and suppressed glucose-stimulated insulin secretion (GSIS) despite increased beta cell mass. The majority of in vitro studies confirm an inhibitory GC effect on insulin secretion. The mechanism remains ambiguous but might involve its direct influence upon expression of molecules essential for glucose sensing and metabolism, enhanced glucose cycling, down-regulated insulin gene transcription, hampered insulin exocytosis, amplified alpha-adrenergic signalling, and/or increased beta-cell apoptosis. There are also reports that suggest increased GSIS after beta cell exposure to GCs in vitro. Transgenic mice with enhanced corticosterone regeneration within their beta cells present augmented secretory capacity of their islets. To summarise, GCs exert a significant role in carbohydrate balance through various mechanisms, including direct impact on beta cell function. Observed discrepancies may arise from differences in study design. A thorough understanding of GC action will provide important clinical clues for disorders of glucose homeostasis. PMID- 29168547 TI - Gastric Contractility Modulation - a novel method for the treatment of type 2 diabetes mellitus and obesity. AB - Because the majority of antidiabetic medications are of limited efficacy and patient compliance with treatment is usually poor, new therapies are still being searched for. In the review a newly developed system for treatment of subjects with type 2 diabetes and concomitant overweight/obesity is described. The system consists of an implantable pulse generator that delivers electrical stimuli through leads implanted in the sero-muscular layer of the stomach. The device recognises and automatically modulates natural electrical activity of the stomach during meals, strengthening gastric contractility. This increase in the force of contractions enhances vagal afferent activity. Modulated signals are transmitted to the regulatory centres in the brain in order to provoke an early response of the gut typical of a full meal. Clinical trials performed to date show that the system improves glycaemic control with minimal patient compliance needed and with added benefits of body weight loss, a decrease in blood pressure, and favourable changes in the lipid profile. The system is safe, well-tolerated, with a low risk of hypoglycaemia, and will probably become an alternative to the use of incretins or to bariatric surgery in obese patients who are unwilling to undergo a major and anatomically irreversible operation. PMID- 29168548 TI - Guidelines for the diagnosis and management of osteoporosis in Poland : Update 2017. AB - In the rapidly ageing society in Poland, osteoporosis is a growing epidemiological problem, and osteoporosis-related fractures are a cause of chronic disability and considerable increase of death risk. It turns out that 80 to 90% of patients suffering from osteoporosis, including osteoporosis accompanied by fractures, do not receive adequate pharmacotherapy. In this paper, a Guideline Working Group of experts from the Multidisciplinary Osteoporosis Forum update the existing Polish guidelines concerning the diagnosis and management of osteoporosis (last revised in 2013), taking account of the latest literature, availability and reimbursement of drugs, and current health care organisation. In the revised guidelines, we still postulate that tasks are divided between primary care doctors (stage I) and specialists in osteoporosis management (stage II). We emphasise the necessity of early initiation of pharmacotherapy and rehabilitation in all patients with low-energy fractures. We recommend that the 10-year fracture risk should be estimated in all patients (including those without fractures) who are over 50 years of age, and that the Polish threshold for therapeutic intervention should be adopted: >= 10% for FRAX PL calculator. We add strategies of drug choice and therapy monitoring with imaging, and densitometric and biochemical diagnostics. We define basic guidelines concerning prevention of falls, rehabilitation, and dietary procedures, and elimination of environmental and other fracture risk factors. We point to two vital elements for improving osteoporosis management: 1) strategy of supervision over fractures management - Fracture Liaison Service (FLS), and, optimally, 2) strategies of short-term monitoring of the therapeutic efficacy with the use of biochemical markers. PMID- 29168549 TI - First Polish analysis of the treatment of advanced heart failure in children with the use of BerlinHeart EXCOR mechanical circulatory support. AB - BACKGROUND: The treatment of advanced heart failure (HF) in children and infants poses a serious management problem. Heart failure in that patient group is usually of congenital aetiology. The treatment schedules for paediatric patients are in most cases adapted from the guidelines for treatment of adults. Up to 2009, the treatment of that extremely difficult group of patients was limited to pharmacological therapy and occasional heart transplantations. Constantly increasing problems with recruiting donors, especially for the paediatric group, contribute to the fact that mechanical support with the use of ventricular assist devices is for many children the only chance of surviving the period of waiting for a heart donor. AIM: The aim of the study was to analyse the outcomes of circulatory support in Poland and to assess the advisability of this method for treatment of children with severe HF. METHODS: This treatment of paediatric patients is currently used in three Polish centres. From December 28, 2009 to August 1, 2015, 27 implantations of BerlinHeart EXCOR(r) mechanical circulatory support system were performed in children aged from one month to 16 years (10 patients below one year of age; 37%). Left ventricular assist devices were implanted to 21 patients, whereas the remaining children received biventricular support. The most common reason for using this method was HF developed in the course of cardiomyopathy. In one case, HF after Fontan operation was the indication. RESULTS: The duration of the circulatory support period ranged from six to 1215 days. It was followed by successful heart transplantations in 10 (37%) patients, in five (18.1%) it resulted in regeneration of the heart, enabling explantation of the device, whereas three children are still waiting for transplantations. Nine (33%) children died during the therapy because of thromboembolic complications. CONCLUSIONS: As follows from our data, circulatory support utilising the BerlinHeart EXCOR(r) system is an effective and promising method used as a bridge to cardiac transplantation, or for regeneration of the myocardium in paediatric patients. In the group of the youngest and the most difficult patients, the method requires close cooperation of the medical and nursing personnel. PMID- 29168550 TI - Automated external defibrillator use in public places: a study of acquisition time. AB - BACKGROUND: Sudden cardiac arrest (SCA) is a frequent cause of death in the developed world. Early defibrillation, preferably within the first minutes of the incident, significantly increases survival rates. Accessible automated external defibrillators (AED) in public areas have been promoted for many years, and several locations are equipped with these devices. AIM: The aim of the study was to assess the real-life availability of AEDs and assess possible sources of delay. METHODS: The study took place in the academic towns of Poznan, Lodz, and Warsaw, Poland. The researchers who were not aware of the exact location of the AED in the selected public locations had to deliver AED therapy in simulated SCA scenarios. For the purpose of the trial, we assumed that the SCA takes place at the main entrance to the public areas equipped with an AED. RESULTS: From approximately 200 locations that have AEDs, 78 sites were analysed. In most places, the AED was located on the ground floor and the median distance from the site of SCA to the nearest AED point was 15 m (interquartile range [IQR] 7-24; range: 2-163 m). The total time required to deliver the device was 96 s (IQR 52 144 s). The average time for discussion with the person responsible for the AED (security officer, staff, etc.) was 16 s (IQR 0-49). The AED was located in open access cabinets for unrestricted collection in 29 locations; in 10 cases an AED was delivered by the personnel, and in 29 cases AED utilisation required continuous personnel assistance. The mode of accessing the AED device was related to the longer discussion time (p < 0.001); however, this did not cause any significant delay in therapy (p = 0.132). The AED was clearly visible in 34 (43.6%) sites. The visibility of AED did not influence the total time of simulated AED implementation. CONCLUSIONS: We conclude that the access to AED is relatively fast in public places. In the majority of assessed locations, it meets the recommended time to early defibrillation of under 3 min from the onset of the cardiac arrest; however, there are several causes for possible delays. The AED signs indicating the location of the device should be larger. AEDs should also be displayed in unrestricted areas for easy access rather than being kept under staff care or in cabinets. PMID- 29168551 TI - Clinical characteristics, and in-hospital and long-term outcomes of stable angina treatment in patients below and over 40 years of age (from the PRESAGE registry). AB - BACKGROUND: There is a paucity of data concerning young patients with stable angina (SA). AIM: The study aimed to compare the characteristics, as well as in hospital one-, two-, and five-year outcomes of patients aged <= 40 and > 40 years with SA. METHODS: The analysis involved 80 patients aged <= 40 years and 9299 patients aged > 40 years with SA treated in the 3rd Department of Cardiology in Zabrze between 2006 and 2014, and enrolled in the ongoing PRESAGE Registry. Propensity scores matching was used to adjust for differences in patients' baseline characteristics. The composite endpoint involved death, non-fatal myocardial infarction, and acute coronary syndrome (ACS) or ACS-driven unplanned revascularisation within one-, two-, and five-year follow-up periods. RESULTS: In comparison to older patients, the younger ones had a higher incidence of smoking (58.3% vs. 35.2%, p < 0.0001) and previous percutaneous angioplasty (45% vs. 33.7%, p = 0.033). There was no significant difference in in-hospital outcomes. The composite endpoint incidence did not differ significantly between the young and old group within one year (1.3% vs. 8.1%, p = 0.068), two years (5.8% vs. 12.9%, p = 0.08), and five years (23.1% vs. 25.7%, p = 0.71) after discharge. Young patients had a borderline lower mortality rate (0% vs. 4.5%, p = 0.053) after a one-year follow-up and a significantly lower mortality rate within two and five years after index hospitalisation (0% vs. 7.8%, p = 0.02 and 5.1% vs. 17.1%, p = 0.04, respectively). After propensity score matching analysis, a significantly lower two-year mortality was observed in the <= 40 age group (0% vs. 8.1%; p = 0.016), without significant difference during five-year follow-up (5.1% vs. 13.5%; p = 0.21). CONCLUSIONS: The younger and older groups of patients with SA differed in clinical characteristics, with no significant difference in the in-hospital outcomes and composite endpoint incidence in the follow-up period. However, younger patients had a borderline lower mortality rate one year after discharge and a significantly lower mortality rate two and five years after the index hospitalisation. PMID- 29168552 TI - Predictors of post-operative atrial fibrillation in patients undergoing isolated coronary artery bypass grafting. AB - BACKGROUND: Post-operative atrial fibrillation (POAF) is the most common cardiac arrhythmia occurring after coronary artery bypass grafting (CABG). Arrhythmia leads to prolonged hospitalisation and may have an impact on both short-term and long-term prognoses. AIM: The aim of this paper was to evaluate the incidence of POAF in patients after CABG as well as to identify its predictors. METHODS: The study was performed on 791 patients (selected from a group of 1031 patients who underwent CABG in the Clinical Department of Cardiology in the years 2009-2011) who did not suffer from atrial fibrillation (AF) prior to isolated CABG. Data on co-existing diseases, as well as data collected at the time of surgery and in the post-operative period, were evaluated. RESULTS: The average age of patients in the examined group was 64.6 +/- 9.1 years. Emergency CABG was performed on 38% of patients, whereas 75.1% of patients underwent CABG with the use of extracorporeal circulation. Based on the incidence of POAF, the post-CABG patients were classified into a POAF(+) group that comprised 166 (21%) patients, and a POAF(-) group involving 625 (79%) patients. The first occurrence of arrhythmia during the first three days after surgery was observed in 76.5% of patients. The average age of POAF(+) and POAF(-) patients was 68.7 +/- 8.8 years and 63.5 +/- 8.9 years, respectively (p < 0.0001). The respective incidence rates of co-existing diseases in patients with POAF and those without POAF were as follows: arterial hypertension, 80.1% vs. 75.8% (p = 0.29); heart failure, 18.7% vs. 21.1% (p = 0.56); type 2 diabetes, 24.1% vs. 26.2% (p = 0.64). Stable angina pectoris was diagnosed in 22.3% of patients with POAF and 15% of patients without POAF (p = 0.034). The following conditions were more frequently observed in patients with POAF compared with those without POAF: low cardiac output syndrome, 28.9% vs. 14.2% (p < 0.0001) and cardiac tamponade, 9% vs. 4.6% (p = 0.044), respectively. Red blood cell transfusions were performed more often in patients with POAF compared to those without POAF (70.5% vs. 55.7%, respectively, p = 0.0008). Multivariate analysis revealed the following potential predictors of POAF: age >= 70 years (HR 2.3), preoperative stable angina pectoris (HR 1.7), and post-CABG low cardiac output syndrome (HR 1.8). CONCLUSIONS: POAF was diagnosed in 21% of post-CABG patients, and the major predictors were: age >= 70 years, preoperative stable angina, as well as low cardiac output syndrome following CABG.

AB - P-type ATPase proteins maintain cellular homeostasis and uphold critical concentration gradients by ATP-driven ion transport across biological membranes. Characterization of single-cycle dynamics by time-resolved X-ray scattering techniques in solution could resolve structural intermediates not amendable to for example crystallization or cryo-electron microscopy sample preparation. To pave way for such time-resolved experiments, we used biochemical activity measurements, Attenuated Total Reflectance (ATR) and time-dependent Fourier Transform Infra-Red (FTIR) spectroscopy to identify optimal conditions for activating a Zn2+ -transporting Type-I ATPase from Shigella sonnei (ssZntA) at high protein concentration using caged ATP. The highest total activity was observed at a protein concentration of 25 mg/mL, at 310 K, pH 7, and required the presence of 20% (v/v) glycerol as stabilizing agent. Neither the presence of caged ATP nor increasing lipid-to-protein ratio affected the hydrolysis activity significantly. This work also paves way for characterization of recombinant metal transporting (Type-I) ATPase mutants with medical relevance. PMID- 29168554 TI - Relation between denaturation time measured by optical coherence reflectometry and thermal lesion depth during radiofrequency cardiac ablation: Feasibility numerical study. AB - BACKGROUND/OBJECTIVE: Radiofrequency (RF) catheter ablation is a minimally invasive medical procedure used to thermally destroy the focus of cardiac arrhythmias. Novel optical techniques are now being integrated into RF catheters in order to detect the changes in tissue properties. Loss of birefringence due to fiber denaturation at around 70 degrees C is related to changes in accumulated phase retardation and can be measured by polarization-sensitive optical coherence reflectometry (PS-OCR). Since irreversible thermal lesions are produced when the tissue reaches 50 degrees C, our goal was to seek the mathematical relationship between both isotherms. MATERIALS AND METHODS: A two-dimensional model based on a coupled electric-thermal problem was built and solved using the finite element method. The model consisted of cardiac tissue, blood, and a non-irrigated electrode with a sensor embedded in its tip to maintain a specific target electrode temperature. Computer simulations were conducted by varying the tissue characteristics. Lesion depth was estimated by the 50 degrees C isotherm, while the denaturation time (TD) was taken as the time at which the 70 degrees C isotherm reached a depth of 0.75 mm (which corresponds to the optical depth reached by PS-OCR technology). RESULTS: A strong correlation (R2 > 0.83) was found between TD and lesion depth and an even stronger correlation (R2 > 0.96) was found between TD and the time required to achieve a specific lesion depth. For instance, the ablation time required to ensure a minimum lesion depth of 3 mm was 1.33 * TD + 3.93 * seconds. CONCLUSIONS: The computer results confirmed the strong relationship between denaturation time and lesion depth and suggest that measuring denaturation time by PS-OCR could provide information on the ablation time required to reach a specific lesion depth.

AB - Anterior open bite (AOB) is one of the most difficult malocclusions to treat and maintain in orthodontics. Malocclusion occurs more frequently in children with disabilities than in healthy children. Surgical correction of severe AOB often requires maxillary impaction to reduce the anterior facial height. The zygomatic buttress area could be a valuable anchorage site to achieve intrusion of maxillary posterior teeth. A 16-year-old boy with mental retardation showing signs of persistence of infantile behavior, decreased cognitive functioning, and psychomotor skill deficits (no identified syndrome) with an AOB was treated by intrusion of maxillary posterior teeth using I-shaped multipurpose titanium miniplate (SK Surgicals, India). A 7 mm AOB was corrected after 6 months of intrusion. The benefits of this treatment as an alternative to conventional orthodontic appliances are significant in subjects who lack the understanding or with manual dexterity to use an orthopedic appliance. PMID- 29168556 TI - Preliminary results of a cohort study of induction chemotherapy-based treatment for locally recurrent rectal cancer. AB - BACKGROUND: A significant number of patients treated for locally recurrent rectal cancer have local or systemic failure, especially after incomplete surgical resection. Neoadjuvant treatment regimens in patients who have already undergone preoperative (chemo)radiotherapy for the primary tumour are limited. The objective of the present study was to evaluate the influence of a neoadjuvant regimen incorporating induction chemotherapy (ICT) in patients with locally recurrent rectal cancer who had preoperative (chemo)radiotherapy for the primary cancer or an earlier local recurrence. METHODS: Patients were treated with a sequential neoadjuvant regimen including three or four cycles of 5-fluorouracil and oxaliplatin-containing chemotherapy. When no progressive disease was found at evaluation, neoadjuvant treatment was continued with chemoradiation therapy (CRRT) using 30 Gy with concomitant capecitabine. If there was a response to ICT, the patient was advised to continue with systemic chemotherapy after CRRT as consolidation chemotherapy while waiting for resection. These patients were compared with patients who received CRRT alone in the same time interval. RESULTS: Of 58 patients who had ICT, 32 (55 per cent) had surgery with clear resection margins, of whom ten (17 per cent) exhibited a pathological complete response (pCR). The remaining 26 patients had 23 R1 and three R2 resections. In 71 patients who received CRRT, a similar rate of R0 (35 patients) and R1 (36) resection was found (P = 0.506), but only three patients (4 per cent) had a pCR (P = 0.015). CONCLUSION: The incorporation of ICT in neoadjuvant regimens for locally recurrent rectal cancer is a promising strategy. PMID- 29168557 TI - Probiotics for vulvovaginal candidiasis in non-pregnant women. AB - BACKGROUND: Vulvovaginal candidiasis (VVC) is estimated to be the second most common form of infection after bacterial vaginosis. The ability of probiotics in maintaining and recovering the normal vaginal microbiota, and their potential ability to resist Candidas give rise to the concept of using probiotics for the treatment of VVC. OBJECTIVES: To assess the effectiveness and safety of probiotics for the treatment of vulvovaginal candidiasis in non-pregnant women. SEARCH METHODS: We searched the following databases to October 2017: Sexually Transmitted Infections Cochrane Review Group's Specialized Register, CENTRAL, MEDLINE, Embase and eight other databases. We searched in following international resources: World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov, Web of Science and OpenGrey. We checked specialty journals, reference lists of published articles and conference proceedings. We collected information from pharmaceutical companies and experts in the field. SELECTION CRITERIA: Randomized controlled trials (RCT) using probiotics, alone or as adjuvants to conventional antifungal drugs, to treat VVC in non-pregnant women. Trials recruiting women with recurrent VVC, coinfection with other vulvovaginal infections, diabetes mellitus, immunosuppressive disorders or taking immunosuppressant medication were ineligible for inclusion. Probiotics were included if they were made from single or multiple species and in any preparation type/dosage/route of administration. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for eligibility and quality and extracted data. We resolved any disagreements through consensus. The quality of the evidence was assessed using the GRADE approach. MAIN RESULTS: Ten RCTs (1656 participants) met our inclusion criteria, and pharmaceutical industry funded none of these trials. All trials used probiotics as adjuvant therapy to antifungal drugs. Probiotics increased the rate of short-term clinical cure (risk ratio (RR) 1.14, 95% confidence interval (CI) 1.05 to 1.24, 695 participants, 5 studies, low quality evidence) and mycological cure (RR 1.06, 95% CI 1.02 to 1.10, 969 participants, 7 studies, low quality evidence) and decreased relapse rate at one month (RR 0.34, 95% CI 0.17 to 0.68, 388 participants, 3 studies, very low quality evidence). However, this effect did not translate into a higher frequency of long-term clinical cure (one month after treatment: RR 1.07, 95% CI 0.86 to 1.33, 172 participants, 1 study, very low quality evidence; three months after treatment: RR 1.30, 95% CI 1.00 to 1.70, 172 participants, one study, very low quality evidence) or mycological cure (one month after treatment: RR 1.26, 95% CI 0.93 to 1.71, 627 participants, 3 studies, very low quality evidence; three months after treatment: RR 1.16, 95% CI 1.00 to 1.35, 172 participants, one study, very low quality evidence). Probiotics use did not increase the frequency of serious (RR 0.80, 95% CI 0.22 to 2.94; 440 participants, 2 studies, low quality evidence). We found no eligible RCTs for outcomes as time to first relapse, need for additional treatment at the end of therapy, patient satisfaction and cost effectiveness. AUTHORS' CONCLUSIONS: Low and very low quality evidence shows that, compared with conventional treatment, the use of probiotics as an adjuvant therapy could increases the rate of short-term clinical and mycological cure and decrease the relapse rate at one month but this did not translate into a higher frequency of long-term clinical or mycological cure. Probiotics use does not seem to increase the frequency of serious or non-serious adverse events. There is a need for well-designed RCTs with standardized methodologies, longer follow-up and larger sample size. PMID- 29168559 TI - Time to stop using uncuffed tracheal tubes in children? PMID- 29168558 TI - Outcomes in women undergoing robotic-assisted laparoscopic hysterectomy compared to conventional laparoscopic hysterectomy at a tertiary hospital in Western Australia. AB - BACKGROUND: Robotic-assisted laparoscopic hysterectomy (RALH) is associated with improved outcomes compared to open surgery in patients with endometrial cancer but data are conflicting when comparing RALH to conventional total laparoscopic hysterectomy (TLH). In October 2014, a RALH program was established in Perth, Western Australia. AIM: To compare outcomes in patients undergoing RALH with a matched cohort undergoing TLH. MATERIALS AND METHODS: A retrospective matched cohort study compared outcomes in 45 patients who underwent RALH with 45 controls who were patients treated with TLH. RESULTS: Mean operating time was longer in the RALH group compared to controls (75.42 min vs 53.18 min, mean difference 22.24 min, P < 0.001, 95% Cl, 11.07-33.42). No differences were observed in mean pain scores (RALH 1.47 vs TLH 1.84 P = 0.31), mean parenteral and oral opioid use (RALH 14.3 mg and 42.4 mg vs TLH 17.5 mg and 52.57 mg, P = 0.42 and 0.42, respectively), and mean length of stay (RALH 1.51 vs TLH 1.67 days, P = 0.49). Two patients in the RALH group and one patient in the TLH group sustained iatrogenic bladder injuries (P = 0.62). CONCLUSION: The establishment of the RALH program at our institution appeared to be associated with equivalent morbidity, post-operative pain, opioid use and length of stay compared to conventional laparoscopy. A surgical learning curve for RALH was observed. Well-designed prospective studies are needed to further evaluate short- and long-term patient function, morbidity, quality of life and oncologic outcomes.

PMID- 29168561 TI - Combination therapy with mifepristone and misoprostol for the management of first trimester miscarriage: Improved success. AB - BACKGROUND: First trimester miscarriage affects 20% of pregnancies. Medical management has a high degree of patient acceptance and does not increase the risk of infection. Mifepristone is an anti-progesterone shown to improve outcomes when used in conjunction with misoprostol for first trimester abortion. However, there have been conflicting results when it has been added to treatment regimens for miscarriage. METHODS: We performed a retrospective cohort analysis of women presenting to the Acute Gynaecology Service of our tertiary referral centre for miscarriage management from December 2010 until December 2013. Patients given misoprostol alone were compared to those who received combination treatment with mifepristone and misoprostol. Primary outcome was failure of treatment determined by the need for repeat medical management or surgical curettage. Secondary outcome was need for hospital admission. RESULTS: A total of 281 women were treated from December 2010 to December 2013: 179 received combined mifepristone and misoprostol and 102 received misoprostol only. The primary outcome was significantly different between the two groups; 73% of women in the mifepristone and misoprostol group required no further treatment compared to only 56% of women in the misoprostol only group (P = 0.012). There were fewer hospital admissions, with 24% in the combined therapy group being admitted compared to 42% in the misoprostol only group (P < 0.001). CONCLUSION: The addition of mifepristone to medical treatment regimens for first trimester miscarriage significantly decreased the need for repeat medical dosing and surgical curettage. Hospital admissions were also significantly decreased. PMID- 29168562 TI - Effect of quality and origin of technical sucrose solutions on the inclusion of colourants into the sugar crystal matrix. AB - BACKGROUND: Due to the liberalisation of the European sugar market the pressure to improve factory utilisation is growing. Currently, beet and cane as sucrose sources are produced in isolation, according to geography. Co-production of sugar from beet and cane origin in one stream is a promising option. However, the knowledge base for production sugar is practically non-existent. This paper is part of our contribution to this field and specifically addresses effects of raw material quality. RESULTS: This framework formulated for the colouring of sugars crystallised from mixed syrups is also valid for different raw material qualities: raw cane sugars: colour values 1221 to 2505 IU, dextran levels 50 to 1200 mg kg-1 ; beet syrups: 1509 to 2058 IU. Co-crystallisation is the main colour incorporation mechanism. Colour due to liquid inclusion increases strongly at cane inclusion levels in excess of 60%. The prediction of final sugar colour based on characteristics of pure mixture constituents is verified and indicates significant differences to current recommendations. CONCLUSION: A first comprehensive description of the colour values in sugars produced from mixed cane and beet syrups is presented. Prediction of colour values from data on sugar colour of single sources marks a major contribution to future applications of co production. (c) 2017 Society of Chemical Industry. PMID- 29168563 TI - Pelvic examination may be meaningfully taught to novices and be used to predict operating times for laparoscopic excision of endometriosis in one surgical procedure. AB - OBJECTIVE: To investigate whether pelvic examination may be meaningfully taught to novice medical students and its accuracy in predicting operating times for laparoscopic excision of endometriosis at a single surgical procedure. METHODS: Women with suspected endometriosis scheduled for laparoscopy underwent pelvic examination to estimate operative time by medical students (novices), trainees, senior clinicians with <10 years surgical experience (experts) and >=10 years (masters). Examination and intraoperative findings were compared and stage of disease recorded. RESULTS: There were 138 estimations of operating time at the initial assessment and 251 estimations of operating time prior to surgery. The median surgical duration was 44 min (range 12-398) and increased progressively with revised American Society for Reproductive Medicine disease stage. Clinical predictions exceeded actual operating times by a median of 18 min (range overestimating by 180 min and underestimating by 120 min) with 80% of procedures completed in less time than predicted and none requiring a second procedure. There was no statistical difference in operative time estimations between the groups with students and trainees underestimating surgical duration by a median of two and five minutes, respectively, experts having a median time difference of zero minutes, and masters overestimating by 4.5 min. CONCLUSION: Targeted pelvic examining may be taught to novices (medical students) and can be used to predict operating time at one surgical procedure. Less experienced examiners have a tendency to underestimate surgical duration, with masters overestimating surgical time when scheduling laparoscopies for endometriosis, and increasing disease stage is associated with a less precise estimation of surgical duration. PMID- 29168564 TI - Grade-related differences in strategy use in multidigit division in two instructional settings. AB - We aimed to investigate upper elementary children's strategy use in the domain of multidigit division in two instructional settings: the Netherlands and Flanders (Belgium). A cross-sectional sample of 119 Dutch and 122 Flemish fourth to sixth graders solved a varied set of multidigit division problems. With latent class analysis, three distinct strategy profiles were identified: children consistently using number-based strategies, children combining the use of column-based and number-based strategies, and children combining the use of digit-based and number based strategies. The relation between children's strategy profiles and their instructional setting (country) and grade were generally in line with instructional differences, but large individual differences remained. Furthermore, Dutch children more frequently made adaptive strategy choices and realistic solutions than their Flemish peers. These results complement and refine previous findings on children's strategy use in relation to mathematics instruction. Statement of contribution What is already known? Mathematics education reform emphasizes variety, adaptivity, and insight in arithmetic strategies. Countries have different instructional trajectories for multidigit division. Mixed results on the impact of instruction on children's strategy use in multidigit division. What does this study add? Latent class analysis identified three meaningful strategy profiles in children from grades 4-6. These strategy profiles substantially differed between children. Dutch and Flemish children's strategy use is related to their instructional trajectory. PMID- 29168565 TI - Growth rates of pulmonary metastases after liver transplantation for unresectable colorectal liver metastases. AB - BACKGROUND: The previously reported SECA study demonstrated a dramatic 5-year survival improvement in patients with unresectable colorectal liver metastases (CLM) treated with liver transplantation (LT) compared with chemotherapy. The objective of this study was to assess whether immunosuppressive therapy accelerates the growth of pulmonary metastases in patients transplanted for unresectable CLM. METHODS: Chest CT scans from 11 patients in the SECA study resected for 18 pulmonary metastases were reviewed retrospectively. Tumour diameter, volume and CT characteristics were registered and tumour volume doubling time was calculated. Findings in the SECA group were compared with those of a control group consisting of 12 patients with non-transplanted rectal cancer resected for 26 pulmonary metastases. Disease-free survival (DFS) and overall survival (OS) after first pulmonary resection were determined. RESULTS: Median doubling time based on tumour diameter and volume in the SECA and control groups were 125 and 130 days (P = 0.658) and 110 and 129 days (P = 0.632) respectively. The metastases in both groups were distributed to all lung lobes and were mostly peripheral. Median DFS after LT in the SECA group and after primary pelvic surgery in the control group was 17 (range 6-42) and 18 (2-57) months respectively (P = 0.532). In the SECA group, estimated 5-year DFS and OS rates after first pulmonary resection were 39 and 51 per cent respectively. CONCLUSION: Patients treated by LT for unresectable CLM have a good prognosis following resection of pulmonary metastases. Doubling time did not appear to be worse with the immunosuppression used after LT. PMID- 29168566 TI - Comparison of subchronic immunotoxicity of four different types of aluminum-based nanoparticles. AB - Nanoparticles (NPs) have recently emerged as an inhalable pollutant, owing to their applications, aluminum-based NPs (Al-NPs) have been prioritized for toxicity testing. In the current study, we compared the pulmonary biopersistence and subsequent toxicity of four different types of Al-NPs (two rod-type aluminum oxide NPs [AlONPs] with different aspect ratios [short (S)- and long (L)-AlONPs], spherical aluminum cerium oxide NPs [AlCeO3 , AlCeONPs] and spherical gamma aluminum oxide hydroxide nanoparticles [AlOOHNPs]) 13weeks after a single intratracheal instillation, considering the importance of their properties in their toxicity. We found that the pulmonary biopersistence of Al-NPs was strengthened by a high aspect ratio in the rod-type AlONPs and by the presence of hydroxyl groups in the spherical-type Al-NPs. The highest toxicity was observed in the mice treated with AlOOHNPs, which showed low biostability. More importantly, we identified that the commercially available AlCeONPs were Al2 O3 coated CeO2 NPs, but not AlCeO3 NPs, although they have been sold under the trade name of AlCeONPs. In conclusion, the aspect ratio and biostability may be important factors in the determination of the biopersistence of NPs and the subsequent biological response. In addition, the physicochemical properties of NPs should be examined in detail before their release into the market to prevent unexpected adverse health effects. PMID- 29168568 TI - Acceptance and transfer to a regional severe respiratory failure and veno-venous extracorporeal membrane oxygenation (ECMO) service: predictors and outcomes. AB - The use of extracorporeal membrane oxygenation for respiratory failure is high risk and resource intensive. In England, five centres provide this service and patients who are referred have four possible outcomes: declined transfer due to perceived futility; accepted in principle but remain at the referring centre with ongoing surveillance; retrieved using conventional ventilation; or retrieved on extracorporeal support. The decision-making process leading to these outcomes has not previously been examined. We evaluated referrals to one centre and identified factors associated with each decision outcome. Five hundred and sixty-four patients were analysed from January 2012 to October 2015. One hundred and fifty seven patients were declined; multivariate analysis demonstrated associated factors to be: age (odds ratio (95% confidence interval) 1.05 (1.04-1.07)); immunocompromise (4.95 (2.58-9.67)); lactate (1.11 (1.01-1.22)); duration of ventilation (1.08 (1.04-1.14)); and cardiac failure (3.22 (1.04-10.51)). Factors associated with the decision to retrieve an accepted patient were: plateau pressure (1.05 (1.01-1.10)); ratio of arterial oxygen partial pressure to fractional inspired oxygen (0.89 (0.85-0.93)); partial pressure of carbon dioxide in arterial blood (1.13 (1.03-1.25)); and the absence of non-pulmonary infection (0.31 (0.15-0.61)). Only pH was independently associated with the decision to transfer on extracorporeal support (0.020 (0.002-0.017)). Six-month survival in the declined, non-retrieved, conventionally retrieved and extracorporeal retrieved groups was 16.6%, 71.1%, 76.7% and 72.1%, respectively, substantially supporting the decision-making model. Survival in the accepted group exceeds that reported previously. However, a proportion of those declined do survive and some remotely managed patients die. This suggests the approach does not account for some important survival-determining factors. PMID- 29168567 TI - Preparation and mechanism analysis of an environment-friendly maize seed coating agent. AB - BACKGROUND: Traditional seed coating agents often contain toxic ingredients, which contaminate the environment and threaten human health. This paper expounds a method of preparing a novel environment-friendly seed coating agent for maize and researches its mechanism of action. The natural polysaccharide polymer, which is the main active ingredient of this environment-friendly seed coating agent, has the characteristics of innocuity and harmlessness, and it can replace the toxic ingredients used in traditional seed coating agents. RESULTS: This environment-friendly seed coating agent for maize was mainly made up of the natural polysaccharide polymer and other additives. The field trials results showed that the control efficacy of Helminthosporium maydis came to 93.72%, the anti-feeding rate of cutworms came to 81.29%, and the maize yield was increased by 17.75%. Besides, the LD50 value (half the lethal dose in rats) of this seed coating agent was 10 times higher than that of the traditional seed coating agents. This seed coating agent could improve the activity of plant protective enzymes (peroxidase, catalase and superoxidase dismutase) and increase the chlorophyll content. CONCLUSION: This seed coating agent has four characteristics of disease prevention, desinsectization, increasing yield and safety. Results of mechanism analyses showed that this seed coating agent could enhance disease control effectiveness by improving plant protective enzymes activity and increase maize yield by improving chlorophyll content.

AB - BACKGROUND: Approximately 600 million children of preschool and school age are anaemic worldwide. It is estimated that at least half of the cases are due to iron deficiency. Point-of-use fortification of foods with micronutrient powders (MNP) has been proposed as a feasible intervention to prevent and treat anaemia. It refers to the addition of iron alone or in combination with other vitamins and minerals in powder form, to energy-containing foods (excluding beverages) at home or in any other place where meals are to be consumed. MNPs can be added to foods either during or after cooking or immediately before consumption without the explicit purpose of improving the flavour or colour. OBJECTIVES: To assess the effects of point-of-use fortification of foods with iron-containing MNP alone, or in combination with other vitamins and minerals on nutrition, health and development among children at preschool (24 to 59 months) and school (five to 12 years) age, compared with no intervention, a placebo or iron-containing supplements. SEARCH METHODS: In December 2016, we searched the following databases: CENTRAL, MEDLINE, Embase, BIOSIS, Science Citation Index, Social Science Citation Index, CINAHL, LILACS, IBECS, Popline and SciELO. We also searched two trials registers in April 2017, and contacted relevant organisations to identify ongoing and unpublished trials. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs trials with either individual or cluster randomisation. Participants were children aged between 24 months and 12 years at the time of intervention. For trials with children outside this age range, we included studies where we were able to disaggregate the data for children aged 24 months to 12 years, or when more than half of the participants were within the requisite age range. We included trials with apparently healthy children; however, we included studies carried out in settings where anaemia and iron deficiency are prevalent, and thus participants may have had these conditions at baseline. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the eligibility of trials against the inclusion criteria, extracted data from included trials, assessed the risk of bias of the included trials and graded the quality of the evidence. MAIN RESULTS: We included 13 studies involving 5810 participants from Latin America, Africa and Asia. We excluded 38 studies and identified six ongoing/unpublished trials. All trials compared the provision of MNP for point-of-use fortification with no intervention or placebo. No trials compared the effects of MNP versus iron-containing supplements (as drops, tablets or syrup).The sample sizes in the included trials ranged from 90 to 2193 participants. Six trials included participants younger than 59 months of age only, four included only children aged 60 months or older, and three trials included children both younger and older than 59 months of age.MNPs contained from two to 18 vitamins and minerals. The iron doses varied from 2.5 mg to 30 mg of elemental iron. Four trials reported giving 10 mg of elemental iron as sodium iron ethylenediaminetetraacetic acid (NaFeEDTA), chelated ferrous sulphate or microencapsulated ferrous fumarate. Three trials gave 12.5 mg of elemental iron as microencapsulated ferrous fumarate. Three trials gave 2.5 mg or 2.86 mg of elemental iron as NaFeEDTA. One trial gave 30 mg and one trial provided 14 mg of elemental iron as microencapsulated ferrous fumarate, while one trial gave 28 mg of iron as ferrous glycine phosphate.In comparison with receiving no intervention or a placebo, children receiving iron-containing MNP for point-of-use fortification of foods had lower risk of anaemia prevalence ratio (PR) 0.66, 95% confidence interval (CI) 0.49 to 0.88, 10 trials, 2448 children; moderate-quality evidence) and iron deficiency (PR 0.35, 95% CI 0.27 to 0.47, 5 trials, 1364 children; moderate-quality evidence) and had higher haemoglobin (mean difference (MD) 3.37 g/L, 95% CI 0.94 to 5.80, 11 trials, 2746 children; low-quality evidence).Only one trial with 115 children reported on all-cause mortality (zero cases; low-quality evidence). There was no effect on diarrhoea (risk ratio (RR) 0.97, 95% CI 0.53 to 1.78, 2 trials, 366 children; low-quality evidence). AUTHORS' CONCLUSIONS: Point-of-use fortification of foods with MNPs containing iron reduces anaemia and iron deficiency in preschool- and school-age children. However, information on mortality, morbidity, developmental outcomes and adverse effects is still scarce. PMID- 29168570 TI - Specific immunotherapy in local allergic rhinitis: A randomized, double-blind placebo-controlled trial with Phleum pratense subcutaneous allergen immunotherapy. AB - BACKGROUND: Allergen immunotherapy has been shown to be an effective treatment for local allergic rhinitis (LAR) to house dust mites. Studies with pollen allergen immunotherapy are limited to observational studies. The aim of this study was to evaluate the clinical efficacy and safety of Phleum pratense subcutaneous immunotherapy (Phl-SCIT) in LAR. METHODS: In a randomized double blind placebo-controlled study, 56 patients with moderate-severe LAR to grass pollen received Phl-SCIT with a depigmented polymerized pollen vaccine or placebo for the first year, and Phl-SCIT the second one. The blind was maintained throughout the study. Primary outcome was combined symptom medication score (CSMS) during grass pollen season (GPS). Secondary clinical outcomes included organ-specific symptoms, medication-free days, rhinitis severity and asthma control. Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), nasal allergen provocation test (NAPT), skin testing, serum levels of specific IgG4 and specific IgE and safety were also evaluated. RESULTS: Subcutaneous immunotherapy (SCIT) had a short-term and sustained effect with significant improvements of all primary and secondary clinical outcomes and RQLQ score. SCIT significantly increased serum sIgG4 levels and allergen tolerance, from the 6th to 24th months of treatment. At the end of the study, 83% of patients treated with >=6 months of SCIT tolerated a concentration of P. pratense over 50 times higher than baseline, and 56% gave a negative NAPT. SCIT was well tolerated; six mild local reactions occurred, and there were no serious adverse events related to the study medication. CONCLUSIONS: Subcutaneous immunotherapy with depigmented polymerized allergen extracts is a safe and clinically effective treatment for LAR to P. pratense. PMID- 29168571 TI - Erratum.

AB - BACKGROUND: Political conflicts in the Palestinian Territories (PT) have resulted in systematic deterioration of socio-economic conditions and health. The World Health Organization (WHO) has emphasised the negative impacts of social crisis on children' oral health and quality of life. OBJECTIVES: To assess the prevalence and trends in dental caries and poor gingival health of schoolchildren in the PT through the scholastic years 1998/1999 to 2012/2013. METHODS: This is a retrospective study. Prevalence data on dental caries of primary and permanent dentitions among children 6, 12 and 16 years of age were gathered from annual oral health reports of the School Dental Health Programme (SDHP)-Ministry of Health. Caries was recorded according to WHO methods and criteria. Decayed, missing and filled teeth indices for primary (dmft) and permanent (DMFT) teeth were calculated. Gingival health status was examined according to the Community Periodontal Index (scores 1 and 2). Statistical analysis used SPSS. RESULTS: In 2012/2013, dental caries prevalence rates and the index scores among schoolchildren were as follows, respectively: 56.4% and 2.7 dmft at age 6; 42.0% and 1.4 DMFT at age 12; and 38.7% and 1.7 DMFT at age 16. For all age groups, the d/D-component of the caries indices was high. Trends of dental-caries prevalence, caries experience and gingival bleeding were fairly constant over time from 1998/1999. CONCLUSION: The SDHP was established in order to prevent and control oral diseases among schoolchildren in the PT. The Programme is fairly passive and the survey indicates an urgent need for reorientation of activities towards population-based prevention and health promotion. The application of the WHO Health Promoting Schools concept is highly recommended. PMID- 29168574 TI - Dental enamel defect diagnosis through different technology-based devices. AB - INTRODUCTION: Dental enamel defects (DEDs) are faulty or deficient enamel formations of primary and permanent teeth. Changes during tooth development result in hypoplasia (a quantitative defect) and/or hypomineralisation (a qualitative defect). OBJECTIVE: To compare technology-based diagnostic methods for detecting DEDs. MATERIAL AND METHODS: Two-hundred and nine dental surfaces of anterior permanent teeth were selected in patients, 6-11 years of age, with cleft lip with/without cleft palate. First, a conventional clinical examination was conducted according to the modified Developmental Defects of Enamel Index (DDE Index). Dental surfaces were evaluated using an operating microscope and a fluorescence-based device. Interexaminer reproducibility was determined using the kappa test. To compare groups, McNemar's test was used. Cramer's V test was used for comparing the distribution of index codes obtained after classification of all dental surfaces. RESULTS: Cramer's V test revealed statistically significant differences (P < .0001) in the distribution of index codes obtained using the different methods; the coefficients were 0.365 for conventional clinical examination versus fluorescence, 0.961 for conventional clinical examination versus operating microscope and 0.358 for operating microscope versus fluorescence. The sensitivity of the operating microscope and fluorescence method was statistically significant (P = .008 and P < .0001, respectively). Otherwise, the results did not show statistically significant differences in accuracy and specificity for either the operating microscope or the fluorescence methods. CONCLUSION: This study suggests that the operating microscope performed better than the fluorescence-based device and could be an auxiliary method for the detection of DEDs. PMID- 29168575 TI - Cuffed vs. uncuffed tracheal tubes in children: a randomised controlled trial comparing leak, tidal volume and complications. AB - Cuffed tracheal tubes are increasingly used in paediatric anaesthetic practice. This study compared tidal volume and leakage around cuffed and uncuffed tracheal tubes in children who required standardised mechanical ventilation of their lungs in the operating theatre. Children (0-16 years) undergoing elective surgery requiring tracheal intubation were randomly assigned to receive either a cuffed or an uncuffed tracheal tube. Assessments were made at five different time points: during volume-controlled ventilation 6 ml.kg-1 , PEEP 5 cmH2 O and during pressure-controlled ventilation 10 cmH2 O / PEEP 5 cmH2 O. The pressure controlled ventilation measurement time-points were: just before a standardised recruitment manoeuvre; just after recruitment manoeuvre; 10 min; and 30 min after the recruitment manoeuvre. Problems and complications were recorded. During volume-controlled ventilation, leakage was significantly less with cuffed tracheal tubes than with uncuffed tracheal tubes; in ml.kg-1 , median (IQR [range]) 0.20 (0.13-0.39 [0.04-0.60]) vs. 0.82 (0.58-1.38 [0.24-4.85]), respectively, p < 0.001. With pressure-controlled ventilation, leakage was less with cuffed tracheal tubes and stayed unchanged over a 30-min period, whereas with uncuffed tracheal tubes, leakage was higher and increased further over the 30-min period. Tidal volumes were higher in the cuffed group and increased over time, but in the uncuffed group were lower and decreased over time. Both groups showed an increase in tidal volumes following recruitment manoeuvres. There were more short-term complications with uncuffed tracheal tubes, but no major complications were recorded in either group at long-term follow-up. With standardised ventilator settings, cuffed tracheal tubes produced better ventilation characteristics compared with uncuffed tracheal tubes during general anaesthesia for routine elective surgery. PMID- 29168576 TI - Clinical value of peripheral blood microRNA detection in evaluation of SOX regimen as neoadjuvant chemotherapy for gastric cancer. AB - BACKGROUND: Neoadjuvant chemotherapy has been widely applied in treating advanced gastric cancer (GC). However, little research has been conducted on evaluating the effect of neoadjuvant chemotherapy. Purpose of this study was to evaluate the effect of SOX regimen as neoadjuvant chemotherapy by detecting some microRNAs. METHODS: Total 120 GC patients who had received neoadjuvant chemotherapy (SOX regimen) were recruited with 100 healthy participants as control contemporarily. Age and gender have no significant difference in both groups (P > .05). The effect of chemotherapy was evaluated by the results of CT scan and surgery. Also, adverse effects of chemotherapy were documented. Peripheral blood of GC patients was collected twice: one day before chemotherapy and surgery, respectively, whereas healthy controls' peripheral blood was collected once. Quantitative real time PCR (qPCR) was utilized to detect expression of miR-145, miR-185, miR-381, and miR-195 of peripheral blood in both groups. RESULTS: One hundred and twenty patients with advanced GC completed a total of 386 cycles of neoadjuvant chemotherapy with effective rate at 84.17% (101 of 120). Expression of miR-145, miR-185, and miR-381 of patients with GC was lower than that in the control group before chemotherapy commence (all P < .05), while the expressions of miR-145 and miR-185 elevated noticeably in CG patients after neoadjuvant chemotherapy (P < .05). The differences in the expression of miR-145 and miR-185 in advanced GC patients with different chemotherapy outcomes were detected. CONCLUSION: Patients with GC at advanced stages had aberrant miRs expressions. Detection of miR-145 and miR-185 expression may assist to predict effectiveness and adverse effects of SOX regimen as neoadjuvant chemotherapy. PMID- 29168578 TI - Utilization of community health workers in Canada's Children's Oral Health Initiative for indigenous communities. AB - OBJECTIVE: The Children's Oral Health Initiative (COHI) is a federally funded community-based preventive dental programme implemented in geographically remote Canadian Indigenous communities. The study investigated the effect of the availability of local community health workers (COHI Aides) on access to the programme's preventive dental services for children. METHODS: Twenty-five communities were continuously enrolled in the COHI during the 7-year study period. Communities were categorized as having uninterrupted (all 7 years), intermittent (>=4 years) or sporadic (<4 years) service from a community health worker. Four outcome variables measured longitudinal changes in access to preventive dental services: (i) the number of enrolments; (ii) the number of enrolled children with multiple fluoride varnishes delivered; (iii) the number of enrolled children with sealants placed; and (iv) the number of enrolled children receiving ART. RESULTS: The general longitudinal trend for programme enrolment and each of the preventive dental service delivery outcomes was similar. Children in communities with uninterrupted service tended to have the highest rates of enrolment and service delivery, which remained constant over time. Children in communities with sporadic service tended to have persistently low rates of enrolment and service delivery over the study period. CONCLUSIONS: Community health workers were beneficial in promoting programme enrolment, as well as facilitating and augmenting the delivery of preventive dental services. PMID- 29168577 TI - Screening for developmental dysplasia of the hip in a rural health district: An analysis of practice. AB - OBJECTIVE: To describe hip dysplasia screening practices in a local rural health district. DESIGN: Cross-sectional study of hospital birth records, local physiotherapy records, public community health electronic medical record (Community Health Information Management Enterprise database) and a survey of local clinicians who work with infants and children. SETTING: Three rural public hospitals and community health centres in a New South Wales health district. PARTICIPANTS: Birth records (n = 196) from March 2012 to May 2012; attendance at child and family nurse checks (n = 788) May 2013-April 2014; 13 cases of managed developmental dysplasia of the hip (DDH) 2012 and local clinicians (n = 49). RESULTS: At birth, the majority of infants (91%, 179/196) had documented hip screening. Community health records show this dropped to 75% (587/788) at 1-4 weeks and 29% (227/788) at 6-8 weeks. A survey of local clinicians (54% response rate; 49/91) revealed most (78%) screen for DDH and less than half (43%) use guidelines. Almost all (97%) clinicians reported screening for DDH at 6-8 weeks of age. Only 51% of clinicians reported having specific training for DDH screening and 76% would like further training. The rate of late DDH requiring management in 2012 was 0.87% (7/806) and the rate of late DDH requiring surgery was 0.25% (2/806). CONCLUSION: DDH screening practices are well established at birth in the rural health district. There is variability in DDH screening practices beyond 8 weeks of age. Clinicians report variations in their knowledge and training. Training in DDH screening and hip screening prompts added to the personal health record might improve rates of DDH screening beyond 8 weeks of age. PMID- 29168579 TI - Organocatalyzed Decarboxylative Trichloromethylation of Morita-Baylis-Hillman Adducts in Batch and Continuous Flow. AB - Two protocols for the organocatalyzed decarboxylative trichloromethylation of Morita-Baylis-Hillman (MBH) substrates have been developed. Applying sodium trichloroacetate, as the trichloromethyl anion precursor, in combination with an organocatalyst and acetylated MBH-alcohols, the desired trichloromethylated products were obtained in good yields at room temperature in batch. The method was next extrapolated into a two-step continuous flow protocol, starting directly from the MBH alcohols, in combination with tributylamine acting both as base and catalyst. The flow process proved superior to the batch approach, reducing the reaction time from 16 hours to only 20 minutes, with increased yields for all investigated entries. Two examples were also taken to scale-up in flow producing more than 10 grams of both trichloromethylated targets. Finally, substitution of the organocatalyst to (DHQ)2 PHAL or (DHQD)2 PHAL induced chiral transfer to the generated stereocenter in the reaction attaining selectivities with nearly 90 % ee.

AB - Resveratrol is a natural phytoestrogen with neuroprotective properties. Polyphenolic compounds including resveratrol exert in vitro antioxidant, anti inflammatory, and antiamyloid effects. Resveratrol and its derivative pterostilbene are able to cross the blood-brain barrier and to influence brain activity. The present short review summarizes the available evidence regarding the effects of these polyphenols on pathology and cognition in animal models and human subjects with dementia. Numerous investigations in cellular and mammalian models have associated resveratrol and pterostilbene with protection against dementia syndromes such as Alzheimer's disease (AD) and vascular dementia. The neuroprotective activity of resveratrol and pterostilbene demonstrated in in vitro and in vivo studies suggests a promising role for these compounds in the prevention and treatment of dementia. In comparison to resveratrol, pterostilbene appears to be more effective in combatting brain changes associated with aging. This may be attributed to the more lipophilic nature of pterostilbene with its two methoxyl groups compared with the two hydroxyl groups of resveratrol. The findings of available intervention trials of resveratrol in individuals with mild cognitive impairment or AD do not provide evidence of neuroprotective or therapeutic effects. Future clinical trials should be conducted with long-term exposure to preparations of resveratrol and pterostilbene with high bioavailability. (c) 2017 BioFactors, 44(1):83-90, 2018. PMID- 29168582 TI - Diagnostic value of trait antinuclear antibodies and multiple immunoglobulin production in autoimmune diseases. AB - BACKGROUND: Our article aims to evaluate the proportion of monospecific antinuclear antibodies (ANA) and polyclonal ANAs in patients with autoimmune diseases based on the results of an ANA panel and to evaluate the efficiency of trait ANAs as a novel diagnostic tool. This study also aims to investigate immunoglobulin production in autoimmune diseases by detecting different antibodies. METHODS: The serum ANA profile of 634 patients with autoimmune diseases was analyzed using the immunoblot method. A specific formula was developed in an effort to calculate the theoretical proportion of monospecific ANA (TPM) in different disease groups. Different IgM, IgG, and IgE variants for several pathologies were detected. RESULTS: The observed proportions of monospecific ANAs (OPM) were all lower than the predicted TPM in autoimmune diseases. Polyclonal ANAs were predominant in patients with systemic lupus erythematosus (SLE). There were statistical differences in OPM and TPM in all disease groups (P < .001). Receiver operating characteristic curve (ROC curve) analysis of trait ANAs between the SLE group and the control groups indicated an area under the curve of 0.916. Differences were found in IgM of Toxoplasma gondii (TOXO) and IgG of hepatitis C virus (HCV) and Treponema pallidum (TP) when comparing the various disease groups to the control group. CONCLUSION: The higher TPM suggests that polyclonal differentiation is the major mechanism of ANA in autoimmune diseases. Trait ANA is potentially a valuable new index for diagnosis in SLE. Further investigation is needed to understand the link between B-cell differentiation and autoimmune diseases. PMID- 29168583 TI - Distinct patterns of amyloid-dependent tau accumulation in Lewy body diseases. AB - BACKGROUND: In addition to Lewy body pathology, amyloid-beta plaques and neurofibrillary tangles that are characteristic for Alzheimer's disease are also frequently found in Lewy body diseases. OBJECTIVES: The objective of this study was to investigate tau accumulation patterns in dementia with Lewy bodies and other Lewy body diseases using in vivo 18 F-AV-1451 PET. METHODS: The study included 12 Parkinson's disease (PD) patients with normal cognition, 22 PD patients with cognitive impairment, and 18 dementia with Lewy bodies patients. In addition, 25 Alzheimer's disease patients and 25 healthy controls were included for comparison. All participants underwent 18 F-AV-1451 and 18 F-florbetaben PET scans, and cortical binding values were compared between the controls and each disease group. RESULTS: When compared with the controls, dementia with Lewy bodies patients showed slightly increased 18 F-AV-1451 binding in the primary sensorimotor and visual cortices and the parieto-temporal cortices, which failed to survive multiple comparisons. Amyloid-positive dementia with Lewy bodies patients showed significantly increased binding in the same regions when compared with controls, and even greater binding in the primary sensorimotor and visual cortices than Alzheimer's disease. Meanwhile, binding in the lateral and medial temporal cortices was less prominent than in Alzheimer's disease. In dementia with Lewy bodies, 18 F-AV-1451 binding in the occipital cortex correlated with 18 F-florbetaben binding. Amyloid-negative patients with normal cognition, patients with cognitive impairment, and dementia with Lewy bodies patients did not show increased 18 F-AV-1451 binding. CONCLUSIONS: Dementia with Lewy bodies patients may harbor 18 F-AV-1451 binding patterns distinct from Alzheimer's disease, with greater involvement of the primary cortices and less involvement of the temporal cortex. Tau burden increases in the Lewy body disease spectrum, and amyloid may play an important role in the accumulation of neocortical tau in Lewy body diseases.

AB - BACKGROUND: Antibodies against tissue transglutaminase (TTG) of isotype IgA (IgA aTTG) represent reliable diagnostic markers to confirm or exclude celiac disease (CD). Hemolysis (HL) is an important pre-analytical factor. HL can be quantified as HL index (HI) correlating with the concentration of free hemoglobin. TTG is abundant in erythrocytes and released upon HL. In immunoassays, the released TTG may interfere with binding of IgA-aTTG to the coated TTG. METHODS: We selected 17 HL-free sera from children with biopsy-confirmed CD: 7 with low-positive (1-5 multiples of upper limit of normal [*ULN]), 5 with intermediate (5-10 * ULN) and 5 with high IgA-aTTG (10-15 * ULN). Sera were spiked with hemolysates resulting in HIs ranging from 12.5 to 800 (12.5-800 mg/dL free hemoglobin). RESULTS: IgA aTTG values were significantly decreased (>10%) after addition of hemolysates even if HL was invisible (HI <50). This effect is diagnosis-relevant if IgA-aTTG values are measured just below the cut-offs: (i) 0.4-1 * ULN at HI >=25 (CD not excludable) and (ii) 8.5-10 * ULN at HI >=200 (diagnosis of CD without biopsy not possible). Antibodies against deamidated gliadin were not influenced by HL. CONCLUSIONS: IgA-aTTG results in sera with HI >=25 can yield inconclusive results. Therefore, those antibody results should be assessed only under consideration of the HI. PMID- 29168585 TI - The prognostic impact of serum bilirubin in stage IV colorectal cancer patients. AB - BACKGROUND: Bilirubin played a great role in antioxidation and anticancer and has been considered as a promising prognostic factor of non-liver disease-related death in various cancers. The aim of this study was to assess the prognostic value of pre-treatment serum bilirubin in stage IV CRC patients. METHODS: Serum bilirubin including TBIL, DBIL, and IBI which were tested at pre-treatment were investigated in 154 stage IV CRC patients in Zhongda Hospital, Nanjing, China, from July 2005 to July 2011. X-tile program was used to determine the optimal cut off values of these three biomarkers. Kaplan-Meier analysis, univariate, and multivariate cox regression as well as time-dependent ROC curve analysis were performed to evaluate the relations between serum bilirubin and survival outcomes. RESULTS: We got the results that the optimal cut-off points of serum TBIL, DBIL, and IBI levels were 12.9, 6.1, and 4.8 MUmol/L, respectively. Univariate analysis showed that elevated TBIL, DBIL, and CEA were significantly associated with poor 5-year OS in stage IV CRC patients. Multivariate cox analysis indicated that the high DBIL (HR=1.603, 95%CI=1.053-2.442, P<.028) and CEA (HR=1.785, 95%CI=1.123-2.837, P=.014) could be identified as independent factors for poor OS. Furthermore, time-dependent ROC curves demonstrated that high DBIL had similar prognostic efficacy as elevated CEA for poor OS (AUC=0.63 and 0.61, respectively). CONCLUSIONS: Pre-treatment elevated TBIL and DBIL levels were associated with poor OS in stage IV CRC patients. Moreover, DBIL could be considered as an independent prognostic biomarker for OS. Furthermore, DBIL had similar prognostic efficacy as CEA for OS. PMID- 29168586 TI - Regional oligodendrocytopathy and astrocytopathy precede myelin loss and blood brain barrier disruption in a murine model of osmotic demyelination syndrome. AB - The osmotic demyelination syndrome (ODS) is a non-primary inflammatory disorder of the central nervous system myelin that is often associated with a precipitous rise of serum sodium concentration. To investigate the physiopathology of ODS in vivo, we generated a novel murine model based on the abrupt correction of chronic hyponatremia. Accordingly, ODS mice developed impairments in brainstem auditory evoked potentials and in grip strength. At 24 hr post-correction, oligodendrocyte markers (APC and Cx47) were downregulated, prior to any detectable demyelination. Oligodendrocytopathy was temporally and spatially correlated with the loss of astrocyte markers (ALDH1L1 and Cx43), and both with the brain areas that will develop demyelination. Oligodendrocytopathy and astrocytopathy were confirmed at the ultrastructural level and culminated with necroptotic cell death, as demonstrated by pMLKL immunoreactivity. At 48 hr post-correction, ODS brains contained pathognomonic demyelinating lesions in the pons, mesencephalon, thalamus and cortical regions. These damages were accompanied by blood-brain barrier (BBB) leakages. Expression levels of IL-1beta, FasL, TNFRSF6 and LIF factors were significantly upregulated in the ODS lesions. Quiescent microglial cells type A acquired an activated type B morphology within 24 hr post correction, and reached type D at 48 hr. In conclusion, this murine model of ODS reproduces the CNS demyelination observed in human pathology and indicates ambiguous causes that is regional vulnerability of oligodendrocytes and astrocytes, while it discards BBB disruption as a primary cause of demyelination. This study also raises new queries about the glial heterogeneity in susceptible brain regions as well as about the early microglial activation associated with ODS. PMID- 29168588 TI - Ovarian response to controlled ovarian stimulation for fertility preservation before oncology treatment: A retrospective cohort of 157 patients. AB - This is a retrospective cohort study aiming to examine the response of oncology patients undergoing controlled ovarian stimulation (COS) for fertility preservation and to review the incidence of short-term complications. The study group consisted by all oncology patients undergoing ovarian stimulation for fertility preservation (n = 157) between April 2009 and April 2016. Patients undergoing COS for IVF/ICSI for male factor only infertility in the same time period (n = 2,128) provided a comparator group. Oncology patients underwent COS to retrieve eggs for storage and future use. The cancer patients had a very similar distribution of oocyte yield to the comparator group. Those with ovarian cancer did have significantly lower oocyte recovery than those with other cancers (age-adjusted difference 7, 95% CI: 2-12). None of the patients in the study group were admitted with ovarian hyperstimulation syndrome or any other complication of COS or oocyte retrieval. This is one of the largest reported cohorts of patients treated for fertility preservation before oncology treatment. Our data have demonstrated a good response to stimulation, offering a reasonable chance of pregnancy in the future. In contrast to previous studies, we have demonstrated a similar number of oocytes retrieved to that of women undergoing IVF/ICSI treatment for male factor infertility. PMID- 29168587 TI - Effect of secondary penicillin prophylaxis on valvular changes in patients with rheumatic heart disease in Far North Queensland. AB - OBJECTIVE: To determine the effect of secondary penicillin prophylaxis on echocardiographic diagnosed valvular changes in patients with rheumatic heart disease or history of acute rheumatic fever in the Townsville Health district. DESIGN: Patients with known were identified from the North Queensland register, serial echocardiogram results and number of secondary penicillin prophylaxis doses received in 2014 were collated. Descriptive statistics were utilised. SETTING: Townsville Hospital and outreach clinics within the Townsville Health catchment zone. PARTICIPANTS: All patients diagnosed with acute rheumatic fever or rheumatic heart disease between 2010 and October 2013 who had serial echocardiograms prior to and post commencement of secondary penicillin prophylaxis were included. All patients were of Aboriginal or Torres Strait Islander descent. MAIN OUTCOME MEASURE: Progression of echocardiographic valvular changes and association with secondary penicillin prophylaxis compliance. Compliance with secondary penicillin prophylaxis among the study population was a secondary outcome measure. RESULTS: Twenty-three patients were recruited. Only those patients who were compliant with secondary penicillin prophylaxis had any improvement in valvular changes on echocardiogram. Four of six patients without any baseline valvular involvement developed new valvular changes. Seventy percent of patients received >75% of secondary penicillin prophylaxis doses. CONCLUSIONS: This small study of patients in Townsville suggests that with good secondary penicillin prophylaxis compliance there is regression of some cardiac lesions over time in people with rheumatic heart disease. Furthermore the natural history of acute rheumatic fever in the Indigenous population is progressive requiring strict adherence to secondary penicillin prophylaxis. Prospective studies or use of data from the nationwide RHD register and standardised reporting of cardiac echocardiograms will provide more robust evidence. PMID- 29168589 TI - Time to delivery: Transfers for threatened preterm labour and prelabour rupture of membranes in Western Australia. AB - OBJECTIVE: To describe the outcomes of patients transferred to King Edward Memorial Hospital (KEMH) with signs of labour at preterm gestations. DESIGN: A retrospective observational study of the 69 cases transferred to KEMH during 2015. SETTING: Patient transfers from all locations across Western Australia (WA) to the sole tertiary perinatal centre in Perth. PARTICIPANTS: Pregnant women within WA with threatened or actual preterm labour (PTL) or preterm prelabour rupture of membranes (PPROM) between 23 and 32 weeks gestation. MAIN OUTCOME MEASURES: The occurrence of delivery during the admission and time-to-delivery as well as length of admission and association between clinical factors and time-to delivery. RESULTS: The percentage of the study population delivered during the admission following transfer was 72.5%. Eighty-six per cent of those who delivered did so within 72 hours of transfer. The median time from transfer to delivery was 1 day. Sixty-three per cent of those who did not deliver during the admission progressed to 36 weeks gestation. Patients transferred with PPROM were less likely to deliver during the admission compared to those with uterine activity (50% versus 19.6%, P = 0.007) and nulliparas were more likely to deliver (93.5% versus 55.3%, P < 0.001). CONCLUSION: The majority of women transferred with signs of PTL progress to delivery during the same admission with the highest risk of delivery being the first 72 hours following transfer. If the pregnancy is ongoing at 72 hours, there is a reasonable chance of progression to late preterm gestation supporting the return of woman to their place of origin for antenatal care following discharge. PMID- 29168590 TI - Clustering patterns of oral and general health-risk behaviours in Brazilian adolescents: Findings from a national survey. AB - OBJECTIVES: To evaluate how oral and general health-risk behaviours cluster among Brazilian adolescents. METHODS: The study comprised a total of 109 104 adolescents (52.2% female) participating in the Brazilian National School-based Student Health Survey (PeNSE). Seventeen behaviours (including diet; oral and hand hygiene; frequency of dental visits; tobacco, alcohol and drug use; sexual behaviour; physical activity, and risk for external causes) were measured using a self-reported questionnaire. Pairwise correlations between the health-risk behaviours were performed, and clustering was assessed by the hierarchical agglomerative cluster analysis (HACA), which was used to identify stable cluster solutions of the health-risk behaviours. RESULTS: All health-risk behaviours were correlated with at least 1 behaviour (P < .01). HACA indicated 2 broad stable clusters (n = 105 604). The first cluster included current smoking, illegal drug use, no hand washing before meals, unprotected sex, no helmet use, less frequent toothbrushing, no seatbelt use, physical fighting, skipping breakfast, current drinking, high sugar intake and, at the final stage, no dental visits. The second cluster included insufficient physical activity, eating while watching TV or studying, and low fruit intake. CONCLUSIONS: The health-risk behaviours clustered into 2 specific patterns among Brazilian adolescents. One cluster gathered a combination of lack of adherence to preventive behaviours and the undertaking of risky conduct, while the second reflected an unhealthy lifestyle (sedentary habits and low fruit diet). Knowledge about the clustering patterns of oral and general health behaviours in adolescents can better direct the integration of oral and general health promotion interventions. PMID- 29168591 TI - Sampling of wide local excision specimens in cutaneous malignant melanoma. AB - BACKGROUND: Wide local excisions (WLEs) are frequently undertaken in the management of cutaneous melanoma; however, there is a considerable variability in their macroscopic sampling. The aim of our study was to establish evidence-based guidelines for the macroscopic handling of these specimens with a subsequent review of the impact on our service. METHODS: The study group of 128 cases with initial biopsy and subsequent WLE in our institution in 2010 were identified by a computer-generated search. From analysis of this group, guidelines for macroscopic sampling were derived with a repeat search performed in 2012. RESULTS: Residual melanoma was detected only in those cases in which the original specimen had clear margins of <=1 mm or with a pigmented lesion. A 32% increase in case numbers was noted over this period with a reduction of 6.2% in block numbers. Average block numbers per case were reduced by 2.3 (30.7%). CONCLUSIONS: We have shown that for WLE specimens with no evidence of a macroscopic lesion and clear margins on original biopsy, little is to be gained from extensive sampling. In these cases we recommend a maximum of 3 blocks per case. Reduction in sampling based on this evidence would result in saving valuable laboratory resources. PMID- 29168593 TI - Respiratory regulation by steroids in newborn rats: a sex-specific balance between allopregnanolone and progesterone receptors. AB - NEW FINDINGS: What is the central question of this study? What are the contributions of allopregnanolone, the neuroactive metabolite of progesterone, and nuclear (nPR) and membrane (mPR) progesterone receptors to the respiratory effect of progesterone in newborn rats? What is the main finding and its importance? Acute progesterone injection increases the apnoea frequency, whereas finasteride (which blocks the conversion of progesterone to allopregnanolone) reduces apnoea frequency. An nPR agonist decreases apnoea frequency in males and an mPR agonist decreases apnoea frequency in males and females. Chronic injection of progesterone decreases the frequency of apnoea more efficiently in males than in females. We tested the hypothesis that the effects of progesterone on apnoea frequency in newborn rats are the result of a balance between its neuroactive metabolite, allopregnanolone (GABAA receptor modulator), and progesterone receptors. We used male and female rats between 10 and 12 days of age and recorded respiratory and metabolic parameters (whole-body plethysmography), and assessed the frequency and duration of apnoeas in normoxia. We tested the effects of a single injection of progesterone (4 mg kg-1 , i.p.), finasteride (10 mg kg-1 , i.p.; a 5alpha-reductase antagonist, which blocks the conversion of progesterone to allopregnanolone), finasteride plus progesterone, or agonists of the nuclear or membrane progesterone receptors (R5020 or Org-od-02-0, 4 mg kg-1 ). To test the hypothesis that chronic exposure to progesterone reduces the frequency of apnoeas, we used male and female rats treated daily with progesterone between postnatal days 3 and 12. The acute injection of progesterone reduced minute ventilation and metabolic rate and increased the frequency of apnoeas. Finasteride decreased the frequency of apnoeas, and finasteride plus progesterone did not increase apnoea frequency but decreased minute ventilation in female rats. Although R5020 decreased apnoea frequency only in males, Org-od 02-0 decreased apnoea frequency in males and females and decreased respiratory frequency in females. Chronic progesterone treatment reduced apnoea frequency more efficiently in males than in females, but in females (not in males) an acute injection of caffeine (the gold standard for the treatment of apnoea in preterm neonates) further reduced apnoea frequency. Apnoea frequency in newborn rats is, in part, determined by a sex-specific balance between allopregnanolone, GABAA receptors and progesterone receptors.

AB - Ynamides, as versatile synthetic precursors, have attracted much attention from synthetic chemists and sparked the development of a number of methodologies for the construction of various structures. 1H-Pyrrolo[2,3-d]carbazole is a core scaffold of a series of monoterpene indole alkaloids found in Kopsia, Strychnos, and Aspidosperma, for example. In this study, 1H-pyrrolo[2,3-d]carbazole derivatives were synthesized by a Bronsted acid-catalyzed tandem cyclization starting from tryptamine-based ynamides. This strategy prevented Wagner-Meerwein rearrangement by instantaneous intramolecular nucleophilic trapping of the indoleninium to afford a tetracyclic indoline via an in situ-formed enol species induced by the formation of a more stable conjugate diene moiety. The functional group tolerances were investigated by using a series of readily available substrates. A plausible mechanism has been proposed based on the evidence of the capture of the hemiaminal intermediate. Lastly, a Buchi ketone, which is the pivotal intermediate in the synthesis of the indole alkaloid vindorosine, was synthesized by utilizing our newly developed methodology. PMID- 29168595 TI - Berberine impairs embryonic development in vitro and in vivo through oxidative stress-mediated apoptotic processes. AB - Berberine, an isoquinoline alkaloid isolated from several traditional Chinese herbal medicines, has been shown to suppress growth and induce apoptosis in some tumor cell lines. However, berberine has also been reported to attenuate H2 O2 induced oxidative injury and apoptosis. The basis for these ambiguous effects of berberine-triggering or preventing apoptosis-has not been well characterized to date. In the current investigation, we examined whether berberine exerts cytotoxic effects on mouse embryos at the blastocyst stage and affects subsequent embryonic development in vitro and in vivo. Treatment of blastocysts with berberine (2.5-10 MUM) induced a significant increase in apoptosis and a corresponding decrease in trophectoderm cell number. Moreover, the implantation success rate of blastocysts pretreated with berberine was lower than that of their control counterparts. Pretreatment with berberine was also associated with increased resorption of postimplantation embryos and decreased fetal weight. In an animal model, intravenous injection of berberine (2, 4, or 6 mg/kg body weight/d) for 4 days resulted in apoptosis of blastocyst cells and early embryonic developmental injury. Berberine-induced injury of mouse blastocysts appeared to be attributable to oxidative stress-triggered intrinsic apoptotic signaling processes that impaired preimplantation and postimplantation embryonic development. Taken together, our results clearly demonstrate that berberine induces apoptosis and retards early preimplantation and postimplantation development of mouse embryos, both in vitro and in vivo. PMID- 29168594 TI - A longitudinal communication approach in advanced lung cancer: A qualitative study of patients', relatives' and staff's perspectives. AB - Communication and the care of patients with advanced cancer are a dynamic, interactive and challenging process, often characterised in every day practice by discontinuity and lack of coordination. The objective of this study was to explore the patients' and family-caregivers' needs and preferences regarding communication, quality of life and care over the trajectory of disease. The second aim was to assess health professionals' views on a longitudinally structured, forward-thinking communication approach based on defined milestones. A qualitative approach was chosen incorporating semi-structured interviews with nine patients with metastatic lung cancer and nine relatives, and focus groups with 15 healthcare providers from different professions involved in the care of these patients. Patients and relatives described a situation of shock and coping deficits with moments of insufficient communication and lack of continuity in care. Healthcare providers reported the strong need for improvement in communication within the team and between patients and professionals and welcomed the implementation of a longitudinal communication approach. Requirements for the implementation of a longitudinal communication approach include specific communication training with focus on the process that patients and relatives are involved in. Team-building measures and the necessary flexibility to respect individuality in life should be incorporated. PMID- 29168596 TI - DNA replication stress and cancer chemotherapy. AB - DNA replication is one of the fundamental biological processes in which dysregulation can cause genome instability. This instability is one of the hallmarks of cancer and confers genetic diversity during tumorigenesis. Numerous experimental and clinical studies have indicated that most tumors have experienced and overcome the stresses caused by the perturbation of DNA replication, which is also referred to as DNA replication stress (DRS). When we consider therapeutic approaches for tumors, it is important to exploit the differences in DRS between tumor and normal cells. In this review, we introduce the current understanding of DRS in tumors and discuss the underlying mechanism of cancer therapy from the aspect of DRS. PMID- 29168597 TI - Reliability and clinical features associated with the IPSG MRI tibiotalar and subtalar joint scores in children, adolescents and young adults with haemophilia. AB - OBJECTIVES: To assess the reliability of the IPSG MRI scale for tibiotalar (TTJ) and subtalar joint (STJ) changes in young haemophilic patients, correlating MRI findings with functional scores and 3D-rearfoot kinematics. METHODS: A total of 37 haemophilic patients underwent bilateral MRI of the footankle, clinical evaluation and quantitative assessment of their 3D-rearfoot kinematics during walking. TTJ and STJ soft tissues were assessed twice along with osteochondral changes by two radiologists using the IPSG MRI scale. Inter- and intra-observer reproducibility of MRI scoring were tested by means of kappa statistics. Correlational analyses were performed between MRI findings and the Haemophilia Joint Health Score 2.1 (HJHS) and 3D-rearfoot kinematic data. RESULTS: The intra reader reliability of MRI scoring was good to excellent (Kappa: 0.62-1), whereas the inter-reader reliability was moderate to good (Kappa: 0.54-0.79). Weak yet significant correlations were found between the frontal plane rearfoot range of motion (ROM) during loading response of gait and STJ score, as well as between frontal plane rearfoot ROM during the terminal stance phase and the rearfoot osteochondral lesions. CONCLUSION: The IPSG score appears applicable to not only the TTJ but also the STJ. Contrary to TTJ lesions, those of the STJ do not correlate with the HJHS but do with 3D-rearfoot kinematic data. PMID- 29168598 TI - PRIMA-1 induces p53-mediated apoptosis by upregulating Noxa in esophageal squamous cell carcinoma with TP53 missense mutation. AB - TP53 is associated with the resistance of cytotoxic treatment and patient prognosis, and the mutation rate of TP53 in esophageal squamous cell carcinoma (ESCC) is extraordinarily high, at over 90%. PRIMA-1 (p53 re-activation and induction of massive apoptosis) has recently been reported to restore the function of mutant TP53; however, its antitumor effect and mechanism in ESCC remain unclear. After evaluating the TP53 mutation status of a panel of 11 ESCC cell lines by Sanger sequencing, we assessed the in vitro effect of PRIMA-1 administration on cells with different TP53 status by conducting cell viability and apoptosis assays. The expression levels of proteins in p53-related pathways were examined by Western blotting, while knockdown studies were conducted to investigate the mechanism underlying PRIMA-1's function. An ESCC xenograft model was further used to evaluate the therapeutic effect of PRIMA-1 in vivo. PRIMA-1 markedly inhibited cell growth and induced apoptosis by upregulating Noxa expression in ESCC cell lines with TP53 missense mutations, whereas no apoptosis was induced in ESCC with wild-type TP53 and TP53 with frameshift and nonsense mutations. Importantly, the knockdown of Noxa canceled the apoptosis induced by PRIMA treatment in ESCC cell lines with TP53 missense mutations. PRIMA-1 administration, compared with placebo, showed a significant antitumor effect by inducing Noxa in the xenograft model of an ESCC cell line with a TP53 missense mutation. PRIMA-1 exhibits a significant antitumor effect, inducing massive apoptosis through the upregulation of Noxa in ESCC with TP53 missense mutations. PMID- 29168600 TI - Molecular characterization of Helicobacter pylori resistance to rifamycins. AB - INTRODUCTION: Antibiotic resistance is a major contributing factor in treatment failure of Helicobacter pylori eradication. Rifabutin (RB) is a rescue treatment and rifampicin (RP) is used to screen RB resistance in vitro. The aim of this study was to evaluate the rate of rifamycins resistance and to determine the mutations in the rpoB gene conferring resistance to discuss the current break point. METHODS: Antimicrobial susceptibility to RP was first determined by E-test for 1015 H. pylori isolates. RP and RB MICs were then determined by agar dilution method for strains with MIC of RP > 1 mg/L, and the rpoB gene was sequenced. RESULTS: Overall, 54 of 1015 strains exhibited a RP MIC > 1 mg/L by agar dilution method. Among these 54 strains, 10 had MICs of RP > 4 mg/L and RB >= 1 mg/L. They all carried at least one mutation in the rpoB gene at codons 530, 538, 540, 525 in the RP resistance-determining region (RRDR). Implication of the mutation L547F was confirmed by site-directed mutagenesis experiment. In contrast, among the 44 H. pylori isolates with a MIC of RP comprised between 2 and 4 mg/L, only 4 of 44 (9%) strains exhibited a mutation in rpoB, but outside RRDR (codons 470, 499, 636, or 657). For 31 of 44 tested strains, the RB MICs were <=0.064 mg/L. CONCLUSION: These results suggest that H. pylori isolates should be classified as resistant to RP for MICs > 4 mg/L. We considered that the optimal cut off for RB was >=0.125 mg/L. We report a new mutation responsible for rifamycins, resistance, L547F. PMID- 29168599 TI - HOXC13 promotes proliferation of esophageal squamous cell carcinoma via repressing transcription of CASP3. AB - Esophageal squamous cell carcinoma (ESCC), the dominant subtype of esophageal cancer, is one of the most common digestive tumors worldwide. In this study, we confirmed that HOXC13, a member of the homeobox HOXC gene family, was significantly upregulated in ESCC and its overexpression was associated with poorer clinical characteristics and worse prognosis. Moreover, knockdown of HOXC13 inhibited proliferation and induced apoptosis of ESCC through upregulating CASP3. ChIP analysis revealed that HOXC13 repressed transcription of CASP3 through directly targeting the promotor region of CASP3. We also found that miR 503 downregulated HOXC13, by directly targeting its 3'UTR, and inhibited proliferation of ESCC. In conclusion, our study demonstrates that HOXC13, which is directly targeted by miR-503, promotes proliferation and inhibits apoptosis of ESCC through repressing transcription of CASP3. PMID- 29168601 TI - Tissue is the issue to confirm benign disease at pleuroscopy in lung cancer. PMID- 29168602 TI - Proliferation genes in lung development associated with the prognosis of lung adenocarcinoma but not squamous cell carcinoma. AB - There are many similarities between embryonic development and tumorigenesis, and gene expression profiles show that certain correlations exist between the gene signature during development and the clinical phenotypes of different cancers. Our group previously reported the gene expression profiles of human lung development, and the expression of one group of proliferation-related genes (PTN1 genes) steadily decreased during lung development. Here, we examined the prognostic value of PTN1 genes in 5 independent lung adenocarcinoma (ADC) and 5 lung independent squamous cell carcinoma (SCC) microarray datasets and found that the expression levels of PTN1 genes were associated with survival in lung ADC but not lung SCC. All of the lung ADC datasets contained a set of highly correlated genes from PTN1 genes, but the lung SCC datasets had no similar set of genes. We identified 63 unique core genes from the PTN1 genes in the 5 lung ADC datasets: 17 of these core genes appeared in at least 4 of the lung ADC datasets, and the 17 corresponding proteins clearly interacted more strongly with each other in lung ADC than in lung SCC. Moreover, 16 of the 17 core genes play major roles in the G2 /M phase of the cell cycle. These data indicate that proliferation-related genes in lung development have a significant prognostic value for lung ADC; the synergistic effects of the 17 core genes play an important role in lung ADC prognosis. These genes may have significant clinical implications for the treatment and prognosis of lung ADC. PMID- 29168604 TI - More evidence needed for association between sleep practices and stillbirth. PMID- 29168603 TI - Eye gaze perception in bipolar disorder: Self-referential bias but intact perceptual sensitivity. AB - OBJECTIVES: Deficits in social cognition predict poor functional outcome in severe mental illnesses such as schizophrenia and autism. However, research findings on social cognition in bipolar disorder (BD) are sparse and inconsistent. This study aimed to characterize a critical social cognitive process-eye gaze perception-and examine its functional correlates in BD to inform psychopathological mechanisms. METHODS: Thirty participants with BD, 37 healthy controls (HC), and 46 psychiatric controls with schizophrenia (SZ) completed an eye-contact perception task. They viewed faces with varying gaze directions, head orientations, and emotion, and made eye-contact judgments. Psychophysics methods were used to estimate perception thresholds and the slope of the perception curve, which were then compared between the groups and correlated with clinical and functional measures using Bayesian inference. RESULTS: Compared with HC, patients with BD over-perceived eye contact when gaze direction was ambiguous, and this self-referential bias was similar to that in SZ. Patients with BD had lower thresholds (i.e., needed weaker eye-contact signal to start perceiving gaze as self-directed) but a similar slope compared with HC. Regression analyses showed that steeper slope predicted better socio-emotional functioning in HC and SZ, but not in BD. CONCLUSIONS: The psychopathology of social dysfunction was fundamentally different between BD and SZ in this modest sample. Eye gaze perception in BD was characterized by a self-referential bias but preserved perceptual sensitivity, the latter of which distinguished BD from SZ. The relationship between gaze perception and broader socio-emotional functioning in SZ and HC was absent in BD. PMID- 29168605 TI - What psychologists need to know about psychotropic medications. AB - Despite the fact that today most of the patients with psychological disturbances assume some form of psychotropic drug treatment, clinical psychologists may have little familiarity with psychopharmacology and are substantially unaware of subtle and yet pervasive potential effects of medications in clinical presentations. In their training, psychologists are generally exposed, at best, to some general principles of drug action. Standard psychopharmacology textbooks tend to omit the subtle psychological changes that may occur during psychotropic drug treatment. Clinical pharmacopsychology consists of the application of clinical psychology to the full understanding of pharmacological effects. The domains of clinical pharmacopsychology encompass the clinical benefits of psychotropic drugs, the characteristics that predict responsiveness to treatment, the vulnerabilities induced by treatment (side effects, behavioural toxicity, iatrogenic comorbidity), and the interactions between drug treatment and psychological variables. The DSM-5 refers to a patient population that no longer exists: subjects who display various manifestations of psychological distress who do not receive any form of drug treatment for it. Any type of psychotropic drug treatment, particularly after long-term use, may increase the risk of experiencing additional psychopathological problems that do not necessarily subside with discontinuation of the drug. The changes may be persistent and not limited to a short phase, such as in the case of withdrawal reactions, and cannot be subsumed under the generic rubrics of adverse events or side effects. PMID- 29168608 TI - Bilateral Awards from European Chemical Societies. PMID- 29168606 TI - Role of seed size, phenology, oogenesis and host distribution in the specificity and genetic structure of seed weevils (Curculio spp.) in mixed forests. AB - Synchrony between seed growth and oogenesis is suggested to largely shape trophic breadth of seed-feeding insects and ultimately to contribute to their co existence by means of resource partitioning or in the time when infestation occurs. Here we investigated: (i) the role of seed phenology and sexual maturation of females in the host specificity of seed-feeding weevils (Curculio spp.) predating in hazel and oak mixed forests; and (ii) the consequences that trophic breadth and host distribution have in the genetic structure of the weevil populations. DNA analyses were used to establish unequivocally host specificity and to determine the population genetic structure. We identified 4 species with different specificity, namely Curculio nucum females matured earlier and infested a unique host (hazelnuts, Corylus avellana) while 3 species (Curculio venosus, Curculio glandium and Curculio elephas) predated upon the acorns of the 2 oaks (Quercus ilex and Quercus pubescens). The high specificity of C. nucum coupled with a more discontinuous distribution of hazel trees resulted in a significant genetic structure among sites. In addition, the presence of an excess of local rare haplotypes indicated that C. nucum populations went through genetic expansion after recent bottlenecks. Conversely, these effects were not observed in the more generalist Curculio glandium predating upon oaks. Ultimately, co existence of weevil species in this multi-host-parasite system is influenced by both resource and time partitioning. To what extent the restriction in gene flow among C. nucum populations may have negative consequences for their persistence in a time of increasing disturbances (e.g. drought in Mediterranean areas) deserves further research. PMID- 29168607 TI - The relationship between perceived organisational threat and compassion for others: Implications for the NHS. AB - The National Health Service (NHS) is known to be a challenging place to work, with financial and performance targets placing increasing pressure on the organisation. This study aimed to investigate whether these pressures and threats might be detrimental to the quality of care and the compassion that the NHS strives to deliver. Quantitative data were collected via self-report questionnaires from healthcare professionals across 3 NHS trusts in England in order to measure Self-compassion; Compassion for Others; Perceived Organisational Threat; and Perceived Organisational Compassion. Qualitative data were also collected to explore the threats considered most pertinent to healthcare professionals at present. The key findings suggest that an increase in Perceived Organisational Threat may reduce an individual's ability to give compassion to others; however, Self-compassion and Perceived Organisational Compassion were better predictors of Compassion for Others. This highlights the need to consider compassion at a systemic level, providing interventions and training not only to cultivate self-compassion in healthcare professionals, but also to encourage compassion across the NHS more generally. In promoting self-compassion and increasing the level of compassion that employees feel they receive at work, healthcare professionals may be better able to maintain or improve their level of compassion for service users and colleagues.

PMID- 29168610 TI - Rural placement experiences in dental education and the impact on professional intentions and employment outcomes-A systematic review. AB - CONTEXT/INTRODUCTION: The availability of clinical dental services in rural locations is a major concern for many countries as dental care professionals gravitate to work in metropolitan areas. This systematic review examines the literature on Rural Placement Programs within dentistry and their impact on workforce intentions and employment outcomes. The review provides a detailed analysis of the methodological characteristics of the literature, considers the quality of the evidence and compares the outcomes within an international context. MATERIALS AND METHODS: The systematic review identified published literature between 2005 and 2016 from databases including EMBASE, MEDLINE, PubMed, NursingOVID and Cochrane. The PRISMA protocol was adopted for the development of the study, and the Health Gains Notation Framework was implemented to assess the quality of the selected research papers. RESULTS: Eleven studies considering Rural Clinical Placement Programs met the inclusion criteria. The studies were from Australia, South Africa, United States, Thailand and India. The evidence in this review indicates that well-designed, financially supported programmes that provide a perceived valuable clinical experience, good supervision and professional support in a rural environment can lead to dental students stating increased intentions to working in a rural location. However, there was a lack of evidence and research into whether these rural intentions result in positive action to take up employment in a rural location. CONCLUSION: The evidence suggests that well-prepared rural clinical placements, which have experienced clinical supervisors, good professional student support from the dental school, provide a valuable clinical experience and are sufficiently funded, can increase intentions to work in a rural location upon graduation. However, there is a lack of evidence in dentistry into whether intentions translate into practitioners taking clinical positions in a rural location. Future research should be planned, which will undertake longitudinal cohort studies to identify factors that have an important influence on rural job choice. PMID- 29168611 TI - Predictive Performance of Physiologically Based Pharmacokinetic Models for the Effect of Food on Oral Drug Absorption: Current Status. AB - A comprehensive search in literature and published US Food and Drug Administration reviews was conducted to assess whether physiologically based pharmacokinetic (PBPK) modeling could be prospectively used to predict clinical food effect on oral drug absorption. Among the 48 resulted food effect predictions, ~50% were predicted within 1.25-fold of observed, and 75% within 2 fold. Dissolution rate and precipitation time were commonly optimized parameters when PBPK modeling was not able to capture the food effect. The current work presents a knowledgebase for documenting PBPK experience to predict food effect. PMID- 29168612 TI - Seed loss before seed predation: experimental evidence of the negative effects of leaf feeding insects on acorn production. AB - Insect herbivory decreases plant fitness by constraining plant growth, survival and reproductive output. Most studies on the effects of herbivory in trees rely on correlational inter-individual comparisons and could, thus, be affected by confounding factors linked to both herbivory and plant performance. Using the Mediterranean Holm oak (Quercus ilex) as a study model, we followed an experimental approach in which leaf-feeding insects (mainly Lepidoptera caterpillars) were excluded from some shoots in all study trees. Shoots subjected to herbivore exclusion exhibited lower defoliation rates and produced more acorns than control shoots. Defoliation constrained shoot growth throughout the study period, but had no effect on the number of female flowers produced per shoot. Acorn production was, however, lower in control shoots due to their higher abortion rates, and also to their greater mortality risk during summer drought, as shoots with fewer leaves were less likely to survive. Plant reaction to herbivory inhibits certain physiological pathways involved in plant growth, which, together with the effects of physical damage, reduces the amount and efficiency of the photosynthetic tissue. This increases their vulnerability to environmental stresses, such as water deficit, which limit resource assimilation. Defoliation is likely a key factor affecting oak regeneration, as it may be a significant source of seed loss prior to pre-dispersal acorn predation. Further experimental studies could help to elucidate its effects in contrasting environments. In Mediterranean regions, the harsher droughts predicted by climate change models could worsen the effects of insect herbivory on oak reproductive output. PMID- 29168613 TI - Immune defense of wild-caught Norway rats is characterized by increased levels of basal activity but reduced capability to respond to further immune stimulation. AB - Studies of wild animals' immunity often use comparison with laboratory-raised individuals. Using such an approach, various data were obtained concerning wild Norway rat's immunity. Lower or higher potential of immune system cells to respond to activation stimuli were shown, because of analysis of disparate parameters and/ or small number of analyzed individuals. Inconsistent differences between laboratory and wild rats were shown too, owing to great response variability in wild rats. We hypothesized that wild rats will express more intense immune activity compared to their laboratory counterparts which live in a less demanding environment. To test this, we analyzed the circulating levels of inflammatory cytokine interleukin-6 (IL-6), a mediator which has a central role in host immune defense. In addition, we examined the activity of the central immune organ, the spleen, including cell proliferation and production of pro inflammatory cytokines interferon-gamma (IFN-gamma) and interleukin-17 (IL-17), which are major effectors of cellular adaptive immune response. In order to obtain reasonable insight into the immunity of wild Norway rats, analysis was conducted on a much larger number of individuals compared to other studies. Higher levels of plasma IL-6, higher spleen mass, cellularity and basal IFN-gamma production concomitantly with lower basal production of anti-inflammatory cytokine interleukin-10 (IL-10) revealed more intense immune activity in the wild compared to laboratory rats. However, lower responsiveness of their spleen cells' proinflammatory cytokine production to concanavalin A (ConA) stimulation, along with preserved capacity of IL-10 response, might be perceived as an indication of wild rats' reduced capability to cope with incoming environmental stimuli, but also as a means to limit tissue damage. PMID- 29168614 TI - Eastern gray squirrels are consistent shoppers of seed traits: insights from discrete choice experiments. AB - Seeds of many hardwood trees are dispersed by scatter-hoarding rodents, and this process is often mediated by the traits of seeds. Although numerous studies have linked seed traits to seed preference by rodents, little is known about how rodents forage for seeds when multiple desirable and undesirable seed traits are available simultaneously. Here, we adopt a novel method of designing choice experiments to study how eastern gray squirrels (Sciurus carolinensis) select for 6 traits (caloric value, protein content, tannin concentration, kernel mass, dormancy period and toughness of shell) among seeds. From n = 426 seed-pair presentations, we found that squirrels preferentially consumed seeds with short dormancy or tougher shells, and preferentially cached seeds with larger kernel mass, tougher shells and higher tannin concentrations. By incorporating random effects, we found that squirrels exhibited consistent preferences for seed traits, which is likely due to the fitness consequences associated with maintaining cached resources. Furthermore, we found that squirrels were willing to trade between multiple traits when caching seeds, which likely results in more seed species being cached in the fall. Ultimately, our approach allowed us to compute the relative values of different seed traits to squirrels, despite covariance among studied traits across seed species. In addition, by investigating how squirrels trade among different seed traits, important insights can be gleaned into behavioral mechanisms underlying seed caching (and, thus, seed survival) dynamics as well as evolutionary strategies adopted by plants to attract seed dispersers. We describe how discrete choice experiments can be used to study resource selection in other ecological systems. PMID- 29168615 TI - Impact of rewilding, species introductions and climate change on the structure and function of the Yukon boreal forest ecosystem. AB - Community and ecosystem changes are happening in the pristine boreal forest ecosystem of the Yukon for 2 reasons. First, climate change is affecting the abiotic environment (temperature, rainfall and growing season) and driving changes in plant productivity and predator-prey interactions. Second, simultaneously change is occurring because of mammal species reintroductions and rewilding. The key ecological question is the impact these faunal changes will have on trophic dynamics. Primary productivity in the boreal forest is increasing because of climatic warming, but plant species composition is unlikely to change significantly during the next 50-100 years. The 9-10-year population cycle of snowshoe hares will persist but could be reduced in amplitude if winter weather increases predator hunting efficiency. Small rodents have increased in abundance because of increased vegetation growth. Arctic ground squirrels have disappeared from the forest because of increased predator hunting efficiency associated with shrub growth. Reintroductions have occurred for 2 reasons: human reintroductions of large ungulates and natural recolonization of mammals and birds extending their geographic ranges. The deliberate rewilding of wood bison (Bison bison) and elk (Cervus canadensis) has changed the trophic structure of this boreal ecosystem very little. The natural range expansion of mountain lions (Puma concolor), mule deer (Odocoileus hemionus) and American marten (Martes americana) should have few ecosystem effects. Understanding potential changes will require long-term monitoring studies and experiments on a scale we rarely deem possible. Ecosystems affected by climate change, species reintroductions and human alteration of habitats cannot remain stable and changes will be critically dependent on food web interactions. PMID- 29168616 TI - Lineage-specific evolution of bitter taste receptor genes in the giant and red pandas implies dietary adaptation. AB - Taste 2 receptors (TAS2R) mediate bitterness perception in mammals, thus are called bitter taste receptors. It is believed that these genes evolved in response to species-specific diets. The giant panda (Ailuropoda melanoleuca) and red panda (Ailurus fulgens styani) in the order Carnivora are specialized herbivores with an almost exclusive bamboo diet (>90% bamboo). Because bamboo is full of bitter tasting compounds, we hypothesized that adaptive evolution has occurred at TAS2R genes in giant and red pandas throughout the course of their dietary shift. Here, we characterized 195 TAS2R genes in 9 Carnivora species and examined selective pressures on these genes. We found that both pandas harbor more putative functional TAS2R genes than other carnivores, and pseudogenized TAS2R genes in the giant panda are different from the red panda. The purifying selection on TAS2R1, TAS2R9 and TAS2R38 in the giant panda, and TAS2R62 in the red panda, has been strengthened throughout the course of adaptation to bamboo diet, while selective constraint on TAS2R4 and TAS2R38 in the red panda is relaxed. Remarkably, a few positively selected sites on TAS2R42 have been specifically detected in the giant panda. These results suggest an adaptive response in both pandas to a dietary shift from carnivory to herbivory, and TAS2R genes evolved independently in the 2 pandas. Our findings provide new insight into the molecular basis of mammalian sensory evolution and the process of adaptation to new ecological niches. PMID- 29168617 TI - Carnivore stable carbon isotope niches reflect predator-prey size relationships in African savannas. AB - Predator-prey size relationships are among the most important patterns underlying the structure and function of ecological communities. Indeed, these relationships have already been shown to be important for understanding patterns of macroevolution and differential extinction in the terrestrial vertebrate fossil record. Stable isotope analysis (SIA) is a powerful remote approach to examining animal diets and paleodiets. The approach is based on the principle that isotope compositions of consumer tissues reflect those of their prey. In systems where resource isotope compositions are distributed along a body size gradient, SIA could be used to reconstruct predator-prey size relationships. We analyzed stable carbon isotope distributions amongst mammalian herbivores in extant and Plio Pleistocene African savanna assemblages, and show that the range of delta13 C values among mammalian prey species (herbivores and rodents) increases with body mass (BM), because C4 plant feeding (essentially grazing) is more common among larger taxa. Consequently, delta13 C values of mammalian carnivores in these systems are related to species' BM, reflecting a higher average C4 prey component in the diets of larger-bodied carnivores. This pattern likely emerges because only the largest carnivores in these systems have regular access to the C4 prey base, whereas smaller carnivores do not. The delta13 C-BM relationship observed in mammalian carnivores is a potentially powerful approach for reconstructing and parameterizing predator-prey size relationships in contemporary and fossil savanna assemblages, and for interpreting how various behavioral, ecological and environmental factors influence prey size selection.

AB - Recent research often lauds the services and beneficial effects of host associated microbes on animals. However, hosting these microbes may come at a cost. For example, germ-free and antibiotic-treated birds generally grow faster than their conventional counterparts. In the wild, juvenile body size is correlated with survival, so hosting a microbiota may incur a fitness cost. Avian altricial nestlings represent an interesting study system in which to investigate these interactions, given that they exhibit the fastest growth rates among vertebrates, and growth is limited by their digestive capacity. We investigated whether reduction and restructuring of the microbiota by antibiotic treatment would: (i) increase growth and food conversion efficiency in nestling house sparrows (Passer domesticus); (ii) alter aspects of gut anatomy or function (particularly activities of digestive carbohydrases and their regulation in response to dietary change); and (iii) whether there were correlations between relative abundances of microbial taxa, digestive function and nestling growth. Antibiotic treatment significantly increased growth and food conversion efficiency in nestlings. Antibiotics did not alter aspects of gut anatomy that we considered but depressed intestinal maltase activity. There were no significant correlations between abundances of microbial taxa and aspects of host physiology. Overall, we conclude that microbial-induced growth limitation in developing birds is not driven by interactions with digestive capacity. Rather, decreased energetic and material costs of immune function or beneficial effects from microbes enriched under antibiotic treatment may underlie these effects. Understanding the costs and tradeoffs of hosting gut microbial communities represents an avenue of future research.

AB - Following a supramolecular synthon rationale, a dicarboxylic acid derivative having a naphthalenediimide (NDI) core, namely, bis-N-carboxymethyl naphthalenediimide (NDI-G), was reacted with n-alkyl amines with varying alkyl chain lengths to generate a new series of primary ammonium dicarboxylate (PAD) salts. The majority of the salts (~85 %) were found to gel various polar solvents. The gels were characterized by dynamic rheology and high-resolution electron microscopy. Single-crystal and powder X-ray diffraction analyses were used to study the supramolecular synthon present in one of the gelator salts (i.e., S8). Charge-transfer (CT)-induced gelation with donor molecules such as anthracene methanol (Ant) and pyrene (Py) was also possible with S8. The CT complex (S8.Ant) displayed anticancer activity as probed by cell migration assay on the highly aggresive breast cancer cell line MDA-MB-231. The DMSO gel of S8.Ant also displayed semiconducting behavior. To the best of our knowledge, simple organic salts with an NDI core that display such mulitifunctional properties are hitherto unknown.

AB - AIMS: This study aimed to describe a method of peripheral muscle training with resistance bands in patients with chronic heart failure (CHF) and to evaluate its effects on the 6 min walk test and quality of life up to 12 months using a home based programme. METHODS AND RESULTS: Twenty-two patients with stable CHF (19 men and 3 women), mean age 63.2 years (SD 8.1), New York Heart Association class II III were randomized to individual home-based training (HT group), or home-based training with a group-based start-up in a hospital setting (GT group). A 6 min walk test, the Minnesota Living with Heart Failure Questionnaire (MLHFQ), and Short Form with 36 items (SF-36) were administered at baseline and after 3, 6, 9, and 12 months. Exercise training resulted in statistically significant increased walking distance in both groups. The HT group increased on average 107 (80) m from baseline to 12 months, and the GT group by 100 (96) m. Health-related quality of life, measured with MLHFQ and SF-36, reached statistically significant improvements in both groups but at different time points. There were no statistically significant differences between groups on any parameters or follow ups. CONCLUSIONS: Long-term home-based peripheral muscle training in patients with CHF, with or without an introductory period in a hospital setting, can be used for initial improvement and retention of walking distance and health-related quality of life.

AB - A patient presented with symptoms of decompensated heart failure 2 months after percutaneous mitral valve (MV) repair. Echocardiography demonstrated impaired left ventricular function with elevated MV pressure gradients and pulmonary pressures during rapid atrial fibrillation. Heart rate control was achieved by implantation of a biventricular pacemaker with subsequent His-bundle ablation because atrial fibrillation was refractory to medical treatment. During biventricular pacing at different rates (50-110 b.p.m.), heart rate correlated positively with both MV mean pressure gradient and global longitudinal strain and negatively with stroke volume. MV pressure gradients directly translated into elevated pulmonary pressures. Thus, rate control and biventricular pacing improved cardiac haemodynamics. PMID- 29168623 TI - Factors shaping life history traits of two proovigenic parasitoids. AB - What shapes the relative investment in reproduction versus survival of organisms is among the key questions in life history. Proovigenic insects mature all their eggs prior to emergence and are short lived, providing a unique opportunity to quantify their lifetime investments in the different functions. We investigated the initial eggloads and longevity of 2 proovigenic parasitoid wasps: Anagrus erythroneurae and Anagrus daanei, (Hymenoptera: Mymaridae) that develop within leafhopper eggs in both agricultural vineyards and natural riparian habitats in Northern California. We collected Vitis spp. leaves containing developing parasitoids from 3 natural sites (Knight Landing, American River and Putah Creek) and 3 agricultural vineyards (Solano Farm, Davis Campus and Village Homes). We recorded eggloads at parasitoid emergence and female parasitoid longevity with or without honey-feeding. Theory predicts that parasitoids from vineyards (where hosts are abundant) would have higher initial eggloads and lower longevity compared with parasitoids from riparian habitats (where hosts are scarce). Although host density and parasitoid eggloads were, indeed, higher in vineyards than in riparian habitats, parasitoid longevity did not follow the predicted pattern. Longevity without feeding differed among field sites, but it was not affected by habitat type (natural vs agricultural), whereas longevity with feeding was not significantly affected by any of the examined factors. Moreover, longevity was positively, rather than negatively, correlated with eggloads at the individual level, even after correcting for parasitoid body size. The combined results suggest a more complex allocation mechanism than initially predicted, and the possibility of variation in host quality that is independent of size. PMID- 29168624 TI - Comparative studies of critical physiological limits and vulnerability to environmental extremes in small ectotherms: how much environmental control is needed? AB - Researchers and practitioners are increasingly using comparative assessments of critical thermal and physiological limits to assess the relative vulnerability of ectothermic species to extreme thermal and aridity conditions occurring under climate change. In most assessments of vulnerability, critical limits are compared across taxa exposed to different environmental and developmental conditions. However, many aspects of vulnerability should ideally be compared when species are exposed to the same environmental conditions, allowing a partitioning of sources of variation such as used in quantitative genetics. This is particularly important when assessing the importance of different types of plasticity to critical limits, using phylogenetic analyses to test for evolutionary constraints, isolating genetic variants that contribute to limits, characterizing evolutionary interactions among traits limiting adaptive responses, and when assessing the role of cross generation effects. On the other hand, vulnerability assessments based on critical thermal/physiological limits also need to take place within a context that is relevant to field conditions, which is not easily provided under controlled environmental conditions where behaviour, microhabitat, stress exposure rates, and other factors will differ from field conditions. There are ways of reconciling these requirements, such as by taking organisms from controlled environments and then testing their performance under field conditions (or vice versa). While comparisons under controlled environments are challenging for many taxa, assessments of critical thermal limits and vulnerability will always be incomplete unless environmental effects within and across generations are considered, and where the ecological relevance of assays measuring critical limits can be established.

PMID- 29168625 TI - Genetic adaptation as a biological buffer against climate change: potential and limitations. AB - Climate change profoundly impacts ecosystems and their biota, resulting in range shifts, novel interactions, food web alterations, changed intensities of host parasite interactions, and extinctions. An increasing number of studies documented evolutionary changes in, amongst others, phenology and thermal tolerance. In this opinion paper, we argue that, while evolutionary responses have the potential to provide a buffer against extinctions or range shifts, a number of constraints and complexities blur this simple prediction. First, there are limits to evolutionary potential both in terms of genetic variation and demographic effects, and these limits differ strongly among taxa and populations. Secondly, there can be costs associated with genetic adaptation, such as a reduced evolutionary potential towards other (human-induced) environmental stressors or direct fitness costs due to trade-offs. Third, the differential capacity of taxa to genetically respond to climate change results in novel interactions because different organism groups respond to a different degree with local compared to regional (cf. dispersal and range shift) responses. These complexities result in additional changes in the selection pressures on populations. We conclude that evolution can provide an initial buffer against climate change for some taxa and populations, but does not guarantee their survival. It does not necessarily result in reduced extinction risks across the range of taxa in a region or continent. Yet, considering evolution is crucial, as it is likely to strongly change how biota will respond to climate change and will impact which taxa will be the winners or losers at the local, metacommunity, and regional scales.

AB - Non-aqueous electrolytes (e.g., organic and ionic liquid electrolytes) can undergo high working voltage to improve the energy densities of supercapacitors. However, the large ion sizes, high viscosities, and low ionic conductivities of organic and ionic liquid electrolytes tend to cause the low specific capacitances, poor rate, and cycling performance of supercapacitors based on conventional micropore-dominant activated carbon electrodes, limiting their practical applications. Herein, we propose an effective strategy to simultaneously obtain high power and energy densities in non-aqueous electrolytes via using a cattle bone-derived porous carbon as an electrode material. Because of the unique co-activation of KOH and hydroxyapatite (HA) within the cattle bone, nitrogen-doped hierarchically porous carbon (referred to as NHPC-HA/KOH) is obtained and possesses a mesopore- and macropore-dominant porosity with an ultrahigh specific surface area (2203 m2 g-1) of meso- and macropores. The NHPC HA/KOH electrodes exhibit superior performance with specific capacitances of 224 and 240 F g-1 at 5 A g-1 in 1.0 M TEABF4/AN and neat EMIMBF4 electrolyte, respectively. The symmetric supercapacitor using NHPC-HA/KOH electrodes can deliver integrated high energy and power properties (48.6 W h kg-1 at 3.13 kW kg 1 in 1.0 M TEABF4/AN and 75 W h kg-1 at 3.75 kW kg-1 in neat EMIMBF4), as well as superior cycling performance (over 89% of the initial capacitance after 10 000 cycles at 10 A g-1).

AB - The variations of the barrier heights in the decomposition of the firefly dioxetanone and its analogues with the electrostatic field produced by the active site amino acid residues in the firefly luciferase are examined by a density functional theory study of the high-energy intermediates of the three luciferins. The positive electric field along the long-axis direction of the luciferins lowers the activation energy and acts as an electrostatic catalyst in the thermolysis process. The calculated barrier heights for the firefly dioxetanone and its analogues surrounded by the firefly Photinus pyralis luciferase show that the energy barrier of the firefly dioxetanone is lowered by the luciferase but is raised for the other analogue. Thus, the thermolysis rate is enhanced for the natural d-luciferin and reduced for the other analogue by the firefly luciferase, which elucidates why the luciferase acts as a catalyst for the natural d luciferin but makes some luciferins emit weaker light signals. PMID- 29168633 TI - Atomic Sulfur Anchored on Silicene, Phosphorene, and Borophene for Excellent Cycle Performance of Li-S Batteries. AB - Dissolution of intermediate lithium polysulfides (LiPS) is an inevitable obstacle for the solid sulfur-based cathode in Li-S batteries. For the first time, herein, atomic sulfur is incorporated into silicene, phosphorene, and borophene to intrinsically eliminate the dissolution of LiPS. The small molecular sulfur species are anchored on the silicene surface with stronger Si-S interaction than the P-S and B-S ones. Meanwhile, a high atomic sulfur coverage (63.1 wt %) is achieved in silicene and concomitantly stabilizes the silicene layer. For the S3 covered silicene, a high theoretical capacity of 857 mA h g-1 is achieved with slight dissolution of LiPS originated from the loss of interior S atoms that are not directly bound with silicene surface. By realizing the elemental S2 coverage on silicene with large surface area, the Li+ ions can react fast with the S2 species, leading to a high theoretical capacity of 891 mA h g-1 without dissolution and migration of the intermediate LiPS. Most interestingly, the discharge products of atomic layer of lithium sulfides on silicene surface exhibit completely different behaviors from the traditional discharge products of solid Li2S, which can function as effective adsorption and activation sites for the conversion of LiPS from long chain to short chain by accelerated redox reaction. The present study gains some key insights into how the atomic sulfur contributes to the intrinsic shuttle inhibition and offers a feasible way to design the atomic sulfur-based cathode materials of Li-S batteries with better electrochemical performance.

AB - Perovskite solar cells (PSCs) have attracted extensive attention due to their impressive photovoltaic performance. The quality of the perovskite layer is very critical to achieve high device performance. Here, we explore the partial substitution of PbI2 by ZnCl2 in the preparation of CH3NH3PbI3 and its effects on perovskite morphology, optical properties, and photovoltaic performance. Consequently, the device with 3% ZnCl2 shows great improvement in power conversion efficiency (PCE) from 16.4 to 18.2% compared to that of the control device. Moreover, the device is more stable than the control device, with only 7% degradation after aging for 30 days. These results are attributed to the increased grain size, improved film morphology, and reduced recombination loss after the partial substitution of PbI2 by ZnCl2 in the perovskite film. This work develops a new approach for morphology control through rational additives in the perovskite film, and paves the way toward further enhancing the device performances of PSCs including PCE and stability. PMID- 29168635 TI - Crystallization Mechanism and Charge Carrier Transport in MAPLE-Deposited Conjugated Polymer Thin Films. AB - Although spin casting and chemical surface reactions are the most common methods used for fabricating functional polymer films onto substrates, they are limited with regard to producing films of certain morphological characteristics on different wetting and nonwetting substrates. The matrix-assisted pulsed laser evaporation (MAPLE) technique offers advantages with regard to producing films of different morphologies on different types of substrates. Here, we provide a quantitative characterization, using X-ray diffraction and optical methods, to elucidate the additive growth mechanism of MAPLE-deposited poly(3-hexylthiophene) (P3HT) films on substrates that have undergone different surface treatments, enabling them to possess different wettabilities. We show that MAPLE-deposited films are composed of crystalline phases, wherein the overall P3HT aggregate size and crystallite coherence length increase with deposition time. A complete pole figure constructed from X-ray diffraction measurements reveals that in these MAPLE-deposited films, there exist two distinct crystallite populations: (i) highly oriented crystals that grow from the flat dielectric substrate and (ii) misoriented crystals that preferentially grow on top of the existing polymer layers. The growth of the highly oriented crystals is highly sensitive to the chemistry of the substrate, whereas the effect of substrate chemistry on misoriented crystal growth is weaker. The use of a self-assembled monolayer to treat the substrate greatly enhances the population and crystallite coherence length at the buried interfaces, particularly during the early stage of deposition. The evolution of the in-plane carrier mobilities during the course of deposition is consistent with the development of highly oriented crystals at the buried interface, suggesting that this interface plays a key role toward determining carrier transport in organic thin-film transistors. PMID- 29168637 TI - Fabrication of Graphene-Polyimide Nanocomposites with Superior Electrical Conductivity. AB - We report on the fabrication of a novel class of lightweight materials, polyimide graphene nanocomposites (0.01-5 vol %), with tunable electrical conductivity. The graphene-polyimide nanocomposites exhibit an ultra-low graphene percolation threshold of 0.03 vol % and maximum dc conductivity of 0.94 S/cm, which we attribute to excellent dispersion, extraordinary electron transport in the well dispersed graphene, high number density of graphene nanosheets, and the pi-pi interactions between the aromatic moieties of the polyimide and the carbon rings in graphene. The dc conductivity data are shown to follow the power-law dependence on the graphene volume fraction near the percolation threshold. The ac conductivity of the nanocomposites is accurately represented by the extended pair approximation model. The exponent s of the approximation is estimated to be 0.45 0.61, indicating anomalous diffusion of charge particles and a fractal structure for the conducting phase, lending support to the percolation model. Low temperature dc conductivity of the nanocomposites is well-approximated by the thermal fluctuation-induced tunneling. Wide-angle X-ray scattering and transmission electron microscopy were utilized to correlate the morphology with the electrical conductivity. The lack of maxima in X-ray indicates the loss of structural registry and short-range ordering.

AB - Menaquinones (naphthoquinones, MK) are isoprenoids that play key roles in the respiratory electron transport system of some prokaryotes by shuttling electrons between membrane-bound protein complexes acting as electron acceptors and donors. Menaquinone-2 (MK-2), a truncated MK, was synthesized, and the studies presented herein characterize the conformational and chemical properties of the hydrophobic MK-2 molecule. Using 2D NMR spectroscopy, we established for the first time that MK-2 has a folded conformation defined by the isoprenyl side-chain folding back over the napthoquinone in a U-shape, which depends on the specific environmental conditions found in different solvents. We used molecular mechanics to illustrate conformations found by the NMR experiments. The measured redox potentials of MK-2 differed in three organic solvents, where MK-2 was most easily reduced in DMSO, which may suggest a combination of solvent effect (presumably in part because of differences in dielectric constants) and/or conformational differences of MK-2 in different organic solvents. Furthermore, MK-2 was found to associate with the interface of model membranes represented by Langmuir phospholipid monolayers and Aerosol-OT (AOT) reverse micelles. MK-2 adopts a slightly different U-shaped conformation within reverse micelles compared to within solution, which is in sharp contrast to the extended conformations illustrated in literature for MKs. PMID- 29168638 TI - Homology Modeling and Molecular Dynamics Simulation Combined with X-ray Solution Scattering Defining Protein Structures of Thromboxane and Prostacyclin Synthases. AB - A combination of molecular dynamics (MD) simulations and X-ray scattering (SAXS) has emerged as the approach of choice for studying protein structures and dynamics in solution. This approach has potential applications for membrane proteins that neither are soluble nor form crystals easily. We explore the water coupled dynamic structures of thromboxane synthase (TXAS) and prostacyclin synthase (PGIS) from scanning HPLC-SAXS measurements combined with MD ensemble analyses. Both proteins are heme-containing enzymes in the cytochrome P450 family, known as prostaglandin H2 (PGH2) isomerase, with counter-functions in regulation of platelet aggregation. Currently, the X-ray crystallographic structures of PGIS are available, but those for TXAS are not. The use of homology modeling of the TXAS structure with ns-MUs explicit water solvation MD simulations allows much more accurate estimation of the configuration space with loop motion and origin of the protein behaviors in solution. In contrast to the stability of the conserved PGIS structure in solution, the pronounced TXAS flexibility has been revealed to have unstructured loop regions in connection with the characteristic P450 structural elements. The MD-derived and experimental solution SAXS results are in excellent agreement. The significant protein internal motions, whole-molecule structures, and potential problems with protein folding, crystallization, and functionality are examined.

AB - BACKGROUND: Hybrid endoscopic submucosal dissection (ESD) has been described as an alternative to traditional ESD. This technique is less time consuming, but the en bloc resection rate is lower than in ESD. Similar to endoscopic mucosal resection, the underwater technique could improve preliminary disadvantages of hybrid ESD. CASE REPORT: We attempted a mixture resection technique of Hybrid ESD with underwater endoscopic mucosal resection (EMR). Using this approach, an underwater hybrid ESD was successfully performed without adverse events on a 71 year old woman with a 20 mm adenoma. The histologic analysis identified a tubulovillious adenoma with high grade dysplasia and tumor free margins. DISCUSSION: Underwater hybrid ESD could be an alternative to ESD. Moreover the modification of the "underwater method" provides a suitable way to overcome the technical drawbacks of the hybrid ESD.

AB - BACKGROUND AND STUDY AIMS: To assess the cost-effectiveness of introducing endoscopic treatment based on radiofrequency ablation plus endoscopic mucosal resection in selected patients into the standard of care of Barrett's esophagus patients with high-grade dysplasia or low-grade dysplasia in Spain. METHODS: The disease evolution was modeled via a semi-Markov model. The treatment strategies compared included endoscopic treatment based on radiofrequency ablation plus endoscopic mucosal resection and the Standard of Care (esophagectomy or palliative chemoradiotherapy according to disease status for high-grade dysplasia and endoscopic surveillance for low-grade dysplasia). Efficacy rates, transition probabilities and utility values were obtained from the literature. Clinical management patterns and resource use were modeled according to Spanish clinical expert opinion. Costs were expressed in euros (?) from 2016 reflecting the Spanish National Health System perspective. Sensitivity analyses were performed to assess the robustness of the model. RESULTS: With respect to the Spanish Standard of Care, endoscopic treatment based on radiofrequency ablation plus endoscopic mucosal resection was a dominant strategy for high-grade dysplasia patients. When a willingness-to-pay threshold of ?30,000 per quality-adjusted life-years gained was considered, this was cost-effective for low-grade dysplasia patients (?12,865 per quality-adjusted life-years gained). The sensitivity analyses supported the base case analysis results and pointed towards the main drivers of uncertainty in the model. CONCLUSIONS: From a health care decision maker, endoscopic treatment based on radiofrequency ablation plus endoscopic mucosal resection is the intervention of choice for dysplasic Barrett's esophagus patients in Spain.

AB - BACKGROUND AND AIM: The human papilloma virus is the leading cause of anal squamous cell carcinoma. Cytological screening may reduce the associated morbidity and mortality. The aim of the study was to estimate the agreement between anal cytological examination, histopathology and anoscopic visual impression. METHODS: A prospective study of patients who underwent anal dysplasia screening between 2011 and 2015, in a proctology clinic of a tertiary referral center. RESULTS: During the study period, 141 patients (91% men, 87% with HIV infection) underwent 175 anal cytology tests. Of these, 33% were negative for intraepithelial lesions or malignancy (NILM), 22% were atypical squamous cells of uncertain significance (ASCUS), 33% were low-grade squamous intraepithelial lesion (LSIL) and 12% were high-grade squamous intraepithelial lesion (HSIL). With regard to anoscopic visual impression, 46% of patients had no lesions and excision/biopsy of the identified lesions was performed in the remaining patients. The weighted kappa-agreement between abnormal cytological results and anoscopic visual impression was moderate (k = 0.48). The weighted kappa-agreement between simultaneous anal cytological examinations and anal histopathologic findings was low (kappa = 0.20). With regard to the histological examination of cases with HSIL or superficially invasive squamous cell carcinoma, 64% of patients had dysplasia of a lower grade according to the cytological analysis (6 ASCUS, 18 LSIL and 4 NILM). CONCLUSION: There was a poor correlation between anal cytology, histopathology and anoscopic visual impression and a high number of histological studies of HGD that were of a lower dysplastic degree according to the cytological examination. Therefore, anal cytology screening should not be used as the sole method of anal dysplasia screening. PMID- 29168647 TI - Pediatric cardiac care in India: current status and the way forward.

MATERIALS & METHODS: The antimicrobial effect of carvacrol and antibiotics against planktonic and biofilm cells were assessed through quantification of the number of culturable and/or viable cells. Confocal laser scanning microscopy was used to evaluate the effect of carvacrol on the biofilm structure. RESULTS: A concentration of 4 mM of carvacrol demonstrated a potent antimicrobial effect, vastly superior than ciprofloxacin, rifampicin, gentamicin and vancomycin, both in planktonic and biofilm cells. CONCLUSION: Carvacrol is a potential antimicrobial agent, which applicability for the prevention and/or treatment of coagulase-negative staphylococci biofilm-associated infections is worthwhile investigating in more detail.

The main point of this review was evaluation of changes in EC area in last few decades, which are not only seen in tumor incidence, but also in its biology, hormonal-metabolic characteristics of patients and in the ratio of risk and anti-risk factors. One can hope that data accumulated recently and summarized here under the notion of EC evolution will find its use for advancement of EC prevention and treatment.

PMID- 29168657 TI - The hidden pathogenic potential of environmental fungi. AB - Invasive fungal infections are a growing threat to immunocompromised patients, highlighting the importance of monitoring fungal pathogens. Global warming (including climatic oscillations) may select for environmental species that have acquired thermotolerance, a key step toward pathogenesis to humans. Also, important virulence factors have developed in environmental fungi, because they are essential for yeast survival in the environment. Thus, fungi traditionally regarded as nonpathogenic to humans have virulence factors similar to those of their pathogenic relatives. Here, we highlight the emergence of saprophytic environmental fungi - including species of Cryptococcus, Aspergillus, Penicillium, Candida and Scedosporium - as new human pathogens. Emerging pathogens are, in some cases, resistant to the available antifungals, potentiating the threat of novel fungal diseases. PMID- 29168660 TI - The interplay between extracellular matrix remodelling and kinase signalling in cancer progression and metastasis. AB - The extracellular matrix (ECM) is a master regulator of cellular phenotype and behaviour. It plays a crucial role in both normal tissue homeostasis and complex diseases such as cancer. The interplay between the intrinsic factors of cancer cells themselves, including their genotype and signalling networks; and the extrinsic factors of the tumour stroma, such as the ECM and ECM remodelling; together determine the fate and behaviour of cancer cells. As a consequence, tumour progression, metastatic spread and response to therapy are ultimately controlled by ECM-driven fine-tuning of intracellular kinase signalling. The ability to target and uncouple this interaction presents an emerging and promising potential in the treatment of cancer. PMID- 29168659 TI - Hydrogel spacers in prostate radiotherapy: a promising approach to decrease rectal toxicity. AB - High-dose radiation is a well-established method of treatment for prostate cancer. The main limiting structure for dose escalation is the rectum. The risk of rectal toxicity is related to dose received by the rectum. Several strategies for reducing dose to rectum have been explored; these include endorectal balloons as well as injection of rectal spacers like hydrogels. They create greater distance between rectal wall and prostate to confer a dosimetric advantage to the rectum. Early clinical studies with hydrogels have shown favorable outcomes. A low incidence of major procedural adverse effects with hydrogel use has been reported and it is well tolerated by patients. Hydrogel holds promise in establishing itself as an adjunct to standard of care in prostate radiation.

AB - Optical coherence tomography (OCT) allows label-free imaging of red blood cell (RBC) flux within capillaries with high spatio-temporal resolution. In this study, we utilized time-series OCT-angiography to demonstrate interruptions in capillary RBC flux in mouse brain in vivo. We noticed ~7.5% of ~200 capillaries had at least one stall in awake mice with chronic windows during a 9-min recording. At any instant, ~0.45% of capillaries were stalled. Average stall duration was ~15 s but could last over 1 min. Stalls were more frequent and longer lasting in acute window preparations. Further, isoflurane anesthesia in chronic preparations caused an increase in the number of stalls. In repeated imaging, the same segments had a tendency to stall again over a period of one month. In awake animals, functional stimulation decreased the observance of stalling events. Stalling segments were located distally, away from the first couple of arteriolar-side capillary branches and their average RBC and plasma velocities were lower than nonstalling capillaries within the same region. This first systematic analysis of capillary RBC stalls in the brain, enabled by rapid and continuous volumetric imaging of capillaries with OCT-angiography, will lead to future investigations of the potential role of stalling events in cerebral pathologies.

AB - There are gaps in HIV care for men who have sex with men (MSM) in African settings, and HIV social stigma plays a significant role in sustaining these gaps. We conducted a three-year research project with 49 HIV-positive MSM in two districts in Mpumalanga Province, South Africa, to understand the factors that inform HIV care seeking behaviors. Semi-structured focus group discussions and interviews were conducted in IsiZulu, SiSwati, and some code-switching into English, and these were audio-recorded, transcribed, and translated into English. We used a constant comparison approach to analyze these data. HIV social stigma centered around gossip that sustained self-diagnosis and delayed clinical care with decisions to use traditional healers to mitigate the impact of gossip on their lives. More collaboration models are needed between traditional healers and health professionals to support the global goals for HIV testing and treatment.

PMID- 29168664 TI - Pulmonary arterial hypertension and acute respiratory distress syndrome in a patient with adult-onset stills disease. AB - Adult-onset Still's disease (AOSD) is an inflammatory disorder characterized by recurrent fevers, arthralgia, leukocytosis, and a salmon-colored rash. Diagnosis is made based on the Yamaguchi criteria. Various cardiac and pulmonary manifestations have been described in association with AOSD, including acute respiratory distress syndrome (ARDS) and pulmonary arterial hypertension (PAH). We describe the first case of both PAH and ARDS in a patient with AOSD who, despite aggressive therapy, declined rapidly and ultimately died. There was concern for pulmonary veno-occlusive disease given the rate of her decompensation, but this was found not to be the case on autopsy. Treatment of AOSD with cardiopulmonary involvement requires rapid identification of AOSD followed by aggressive immunosuppression. PMID- 29168665 TI - The clinicopathological parameters significance of CD133 and Nestin in epithelial ovarian cancer: a meta-analysis. AB - This meta-analysis was conducted to evaluate the association of CD133 and Nestin with epithelial ovarian cancer. Databases (PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure, Wanfang) were searched for relevant studies updated in August 2017. CD133 and Nestin expression were estimated by immunohistochemistry. Statistical analysis was performed by RevMan. A total of 18 studies were included in this meta-analysis. High expression of both CD133 and Nestin was associated with late International Federation of Gynecology and Obstetrics stage (p < 0.00001), larger size of residual cancer (p < 0.05). CD133 overexpression was also associated with higher histological grade (p = 0.0006) and lymph node metastases (p < 0.00001). Nestin overexpression was associated with a higher rate of treatment resistance (p = 0.0007). Positive expression of CD133 and Nestin may be associated with aggressive biological behaviors in epithelial ovarian cancer. PMID- 29168666 TI - Diagnostic methods used in searching for markers of atrophy in patients with multiple sclerosis. AB - : The results of available studies on assessment of neurodegenerative lesions in multiple sclerosis (MS) patients using different approaches have not been conclusive. Currently, clinical assessment is the most commonly used (involving primarily mobility assessment), along with magnetic resonance imaging and electrophysiological testing. In this review we describe available clinical, neuroimaging, electrophysiological and laboratory tests used to assess the neurodegeneration in MS. Laboratory markers to determine the risk of disease, its conversion and prognosis in MS patients are being constantly sought. Cerebrospinal fluid (CSF) sample collection is invasive and constitutes a burden to a patient, so serum biomarkers are being investigated. Optimistic preliminary results of studies assessing neurofilament light chains (NFL) in serum of MS patients, encourage further research. The possibility to use such marker (or a group of markers) would significantly facilitate clinical decisions at the stage of diagnosis and treatment. Currently used treatments have limited efficacy and are associated with numerous adverse effects. Additional information from available clinical, imaging, electrophysiological or laboratory biomarker or a group of biomarkers, which predict the course and prognosis, will facilitate choosing optimal treatment and its escalation at the relevant stage. CONCLUSION: Using the diagnostic panel consisting of imaging, neurophysiology and serology testing along with clinical and neuropsychological assessment may improve the reliability of diagnostic instruments evaluating cerebral atrophy in MS patients. PMID- 29168668 TI - The occurrence of fractures after adjuvant treatment of breast cancer: a DBCG register study. AB - BACKGROUND: Adjuvant treatment in breast cancer patients especially with aromatase inhibitors (AIs) has adverse effects on bone metabolism resulting in an increased occurrence of fractures. In order to demonstrate this occurrence, long term follow-up studies are necessary. From several national registries in Denmark, it is possible to link data from different sources and analyze this issue. METHODS: A study cohort of 68,842 breast cancer patients prospectively diagnosed and registered in the Danish Breast Cancer Cooperative Group's database during the period 1995-2012 formed the basis of the analysis. These data were matched with data on all types of fractures from the Danish National Patient Register and vital data from the Danish Civil Registration System. RESULTS: After data cleaning 66,502 patients were available for analysis and 16,360 of these had incurred 20,341 fractures with 13,182 patients having just one fracture. These fractures were distributed over 214 specific fracture sites. An extended multivariable Cox regression model revealed significant association between the occurrence of fractures and age, menopause, Charlson comorbidity index (CCI) and endocrine therapy such that late menopause and tamoxifen treatment were associated with a lower occurrence and AI treatment, age and CCI were associated with a higher occurrence of fractures. CONCLUSION: Before advising adjuvant therapy with AIs fragile patients with chronic diseases should receive special attention in order to reduce the incidence of fractures in this vulnerable group of patients. PMID- 29168669 TI - Awake craniotomy versus craniotomy under general anesthesia for the surgical treatment of insular glioma: choices and outcomes. AB - OBJECTIVE: To investigate differences in outcomes in patients who underwent surgery for insular glioma using an awake craniotomy (AC) vs. a craniotomy under general anesthesia (GA). METHODS: Data from patients treated at our hospital between 2005 and 2015 were analyzed retrospectively. The preoperative, intraoperative, postoperative, and longer term follow-up characteristics and outcomes of patients who underwent surgery for primary insular glioma using either an AC or GA were compared. RESULTS: Of the 52 identified patients, 24 had surgery using an AC and 28 had surgery under GA. The extent of resection was similar for the two anesthesia techniques: the median extent of resection was 61.4% (IQR: 37.8-74.3%) in the WHO grade <4 AC group vs. 50.5% (IQR: 35.0-71.2%) in the grade <4 GA group and 73.4% (IQR: 54.8-87.2%) in the grade 4 AC group vs. 88.6% (IQR: 61.2-93.0%) in the grade 4 GA group. Consistent with literature, there were more early neurological deficits after an AC, while the GA group showed more new late neurological deficits; however, these trends were not significant. Survival was similar between the two groups, with 100% 1- and 2-year survival in the grade <4 groups. CONCLUSION: Our results showed that the extent of resection, neurological outcomes, and survival were similar using the two anesthesia techniques. Since AC is more challenging for the patient and for his or her caregiver after surgery, this finding has implications for clinical decision-making. PMID- 29168670 TI - Influence of the revision of surgical fee schedule on surgeons' productivity in Japan: A cohort analysis of 7602 surgical procedures in 2013-2016. AB - The goal of this study is to evaluate the pure impact of the revision of surgical fee schedule on surgeons' productivity. We collected data from the surgical procedures performed by the surgeons working in Teikyo University Hospital from 1 April through 30 September in 2013-2016. We employed non-radial and non-oriented Malmquist model. We defined the decision-making unit as a surgeon with the highest academic rank in surgery. Inputs were defined as (1) the number of doctors who assisted surgery and (2) the time of surgical operation. The output was defined as the surgical fee for each surgery. We focused on the revisions in 2014 and 2016. We first calculated each surgeon's natural logarithms of the changes in productivity, technique and efficiency in 2013-2014, in 2014-2015 and in 2015-2016. Then, we subtracted the changes in 2014-2015 from the changes in 2013-2014 and in 2015-2016. We analyzed 62 surgeons who performed 7602 surgical procedures. The productivity changes were not significantly different from 0. Their efficiency change was significantly greater than 0, while their technical change was smaller than 0 in revision 2014. Their efficiency change was significantly smaller than 0, while their technical change was greater than 0 in revision 2016 (p < 0.05). This finding suggests that we could increase overall productivity through revision if we could increase both efficiency and technique. PMID- 29168667 TI - Arterial spin labeling for the measurement of cerebral perfusion and angiography. AB - Arterial spin labeling (ASL) is an MRI technique that was first proposed a quarter of a century ago. It offers the prospect of non-invasive quantitative measurement of cerebral perfusion, making it potentially very useful for research and clinical studies, particularly where multiple longitudinal measurements are required. However, it has suffered from a number of challenges, including a relatively low signal-to-noise ratio, and a confusing number of sequence variants, thus hindering its clinical uptake. Recently, however, there has been a consensus adoption of an accepted acquisition and analysis framework for ASL, and thus a better penetration onto clinical MRI scanners. Here, we review the basic concepts in ASL and describe the current state-of-the-art acquisition and analysis approaches, and the versatility of the method to perform both quantitative cerebral perfusion measurement, along with quantitative cerebral angiographic measurement. PMID- 29168672 TI - Acute diffusion-weighted imaging lesions in cerebral amyloid angiopathy-related convexal subarachnoid hemorrhage. AB - Small acute diffusion-weighted imaging (DWI) lesions can accompany intracerebral hemorrhage due to cerebral amyloid angiopathy (CAA). We therefore examined the occurrence of such lesions in the context of CAA-related convexal subarachnoid hemorrhage (cSAH) both in a cross-sectional and longitudinal manner. DWI lesions were noted in 14/29 (48%) patients at their index cSAH and 12/21 patients (57%) showed acute small DWI lesions at follow-up MRI. Forty-four of 71 (62%) DWI lesions were spatially related to areas of cortical superficial siderosis. Clarification of the implications of our finding needs the investigation of larger patient groups. PMID- 29168671 TI - Oral bioavailability enhancement of raloxifene by developing microemulsion using D-optimal mixture design: optimization and in-vivo pharmacokinetic study. AB - The objective of this work was to utilize a potential of microemulsion for the improvement in oral bioavailability of raloxifene hydrochloride, a BCS class-II drug with 2% bioavailability. Drug-loaded microemulsion was prepared by water titration method using Capmul MCM C8, Tween 20, and Polyethylene glycol 400 as oil, surfactant, and co-surfactant respectively. The pseudo-ternary phase diagram was constructed between oil and surfactants mixture to obtain appropriate components and their concentration ranges that result in large existence area of microemulsion. D-optimal mixture design was utilized as a statistical tool for optimization of microemulsion considering oil, Smix, and water as independent variables with percentage transmittance and globule size as dependent variables. The optimized formulation showed 100 +/- 0.1% transmittance and 17.85 +/- 2.78 nm globule size which was identically equal with the predicted values of dependent variables given by the design expert software. The optimized microemulsion showed pronounced enhancement in release rate compared to plain drug suspension following diffusion controlled release mechanism by the Higuchi model. The formulation showed zeta potential of value -5.88 +/- 1.14 mV that imparts good stability to drug loaded microemulsion dispersion. Surface morphology study with transmission electron microscope showed discrete spherical nano sized globules with smooth surface. In-vivo pharmacokinetic study of optimized microemulsion formulation in Wistar rats showed 4.29-fold enhancements in bioavailability. Stability study showed adequate results for various parameters checked up to six months. These results reveal the potential of microemulsion for significant improvement in oral bioavailability of poorly soluble raloxifene hydrochloride. PMID- 29168673 TI - The role of dalbavancin in the multi-disciplinary management of wound infections in orthopaedic surgery. AB - Antimicrobial resistance is continuously increasing among bacterial clinical isolates (especially methicillin resistance in Staphylococcus aureus, MRSA), negatively impacting on outcomes of patients with Surgical Site Infections (SSIs). A multi-disciplinary team work is essential for SSIs prevention and for the choice of antibiotic therapy of orthopaedic SSIs. In particular, an Antibiotic Stewardship (AS) approach is recommended for preserving the activity of old and new antimicrobials. Dalbavancin is a novel antimicrobial agent, belonging to the lipoglycopeptides family, recently approved by FDA for the treatment of ABSSSIs (Acute Bacterial Skin and Skin Structure Infections) and can be considered as a candidate for the treatment of orthopaedic superficial SSIs. An antimicrobial activity directed against MRSA and other multi-resistant Gram positive pathogens, a bactericidal effect and an extremely extended half-life are among key features of this drug. Dalbavancin gives to clinicians the option to provide an intravenous antimicrobial agent shown to be as effective as conventional therapies, without requiring prolonged admission into the hospital, drastically reducing the length of hospital stay (without reducing the treatment compliance) and total cost per patient. In this paper, we analyze general, microbiological and pharmacological features of dalbavancin, aiming at supporting clinicians while positioning this drug in the context of orthopaedic SSIs. PMID- 29168674 TI - Breast conserving surgery versus mastectomy: overall and relative survival-a population based study by the Danish Breast Cancer Cooperative Group (DBCG). AB - BACKGROUND: Observational studies have pointed at a better survival after breast conserving surgery (BCS) compared with mastectomy. The aim of the present study was to evaluate whether this remains true when more extensive tumor characteristics and treatment data were included. METHODS: The cohort included patients registered after primary surgery for early invasive breast cancer in the database of the Danish Breast Cancer Cooperative Group, in the period 1995-2012. The cohort was divided into three groups: (i) patients who primarily had a mastectomy, (ii) patients treated by BCS, and (iii) patients who primarily had BCS and then mastectomy [intention to treat (ITT) by BCS]. The association between overall mortality and standard mortality ratio (SMR) and risk factors was analyzed in univariate and multivariate Poisson regression models. RESULTS: A total of 58,331 patients were included: 27,143 in the mastectomy group, 26,958 in the BCS group, and 4230 in the BCS-ITT group. After adjusting for patient and treatment characteristics, the relative risk (RR) was 1.20 (95% CI: 1.15-1.25) after mastectomy and 1.08 (95% CI: 1.01-1.15) after BCS first and then mastectomy, as compared to BCS. Statistically significant interactions were not observed for age, period of treatment, and nodal status, but patients with Charlson's Comorbidity Index (CCI) score 2+ had no increased mortality after mastectomy, as opposed to patients with CCI 0-1. Loco-regional radiation therapy (RT) in node positive patients did not reduce the increased risk associated with mastectomy [RR = 1.28 (95% CI 1.19-1.38)]. CONCLUSION: Patients assigned to BCS have a better survival than patients assigned to mastectomy. Residual confounding after adjustment for registered characteristics presumably explained the different outcomes, thus consistent with selection bias. Diversities in RT did not appear to explain the observed difference in survival after BCS and mastectomy. PMID- 29168675 TI - Genome characterization of Turkey Rotavirus G strains from the United States identifies potential recombination events with human Rotavirus B strains. AB - Rotavirus G (RVG) strains have been detected in a variety of avian species, but RVG genomes have been published from only a single pigeon and two chicken strains. Two turkey RVG strains were identified and characterized, one in a hatchery with no reported health issues and the other in a hatchery with high embryo/poult mortality. The two turkey RVG strains shared only an 85.3 % nucleotide sequence identity in the VP7 gene while the other genes possessed high nucleotide identity among them (96.3-99.9 %). Low nucleotide percentage identities (31.6-87.3 %) occurred among the pigeon and chicken RVG strains. Interestingly, potential recombination events were detected between our RVG strains and a human RVB strain, in the VP6 and NSP3 segments. The epidemiology of RVG in avian flocks and the pathogenicity of the two different RVG strains should be further investigated to understand the ecology and impact of RVG in commercial poultry flocks.

AB - Social media channels such as Twitter, Facebook, and LinkedIn have been used as tools in health care research, opening new horizons for research on health related topics (e.g., the use of mobile social networking in weight loss programs). While there have been efforts to develop ethical guidelines for internet-related research, researchers still face unresolved ethical challenges. This article investigates some of the risks inherent in social media research and discusses how researchers should handle challenges related to confidentiality, privacy, and consent when social media tools are used in health-related research. PMID- 29168676 TI - Molecular and phylogenetic analyses of influenza B viruses isolated from pediatric inpatients in South Korea during the 2011-2012 winter season. AB - Influenza B virus remains a major cause of respiratory diseases worldwide. Because of limited epidemiological and genetic data, the local and global transmission patterns of influenza B virus are not fully understood. Here we report the molecular and phylogenetic characterization of 163 influenza B virus isolates from pediatric inpatients with influenza-like illness in the winter of 2011-2012 in South Korea. Analysis of haemagglutinin and neuraminidase genes of the influenza B isolates revealed that both B/Victoria (62 %) and B/Yamagata lineages (38 %) co-circulated during that influenza season, and a considerable number of the isolates carried several amino acid substitutions in the four major antigenic epitopes of their haemagglutinin protein. PMID- 29168678 TI - What Critical Ethical Values Guide Strategic Planning Processes in Health Care Organizations? AB - This case explores a fictitious hospital's use of co-creation to make a decision about redesign of inpatient units as a first step in incorporating stakeholder input into creation of governing policies. We apply a "procedural fairness" framework to reveal that conditions required for an ethical decision about space redesign were not met by using clinician and patient focus groups to obtain stakeholder input. In this article, we identify epistemic injustices resulting from this process that could undermine confidence in leadership decisions. Suggestions are offered for incorporating stakeholder input going forward that address prior shortcomings. The result should be conditions that are perceived as procedurally fair and decisions that engender confidence in institutional leadership. PMID- 29168679 TI - What Should Leaders Do When Inefficiency Is Perceived as a Cost of Inclusivity in Strategic Planning Processes in Health Care? AB - During the development of new health care policies, quality improvement teams can face the challenge of weighing differing opinions within the group that can hinder progress. It is essential in such cases to refer to the four keys principles of quality improvement (QI) as a guide to enhance group cooperation and promote development of the mutual objective. Co-production is a model that emphasizes the participation of the patient-a service receiver-in the production of services being rendered by the health care professional. By putting into practice the QI principles and using the model of co-production, quality improvement teams can improve efficiency of health systems and clinical outcomes. PMID- 29168680 TI - Should Health Care Organizations Use Information Gleaned from Organization Sponsored Patient Support Groups in Strategic Planning? AB - Online forums and partnerships with patients have several benefits, such as the creation of new products and services. However, as with any such initiatives, there are risks as well as benefits. Through analysis of a case of misinformation being spread through a health care provider-sponsored online support group for patients dealing with obesity, this article outlines best practices and strategies to deploy in such organization-sponsored patient support groups. These strategies would enable organizations and patients to use such forums to the fullest extent while preventing or managing their potential risks as best as possible. PMID- 29168681 TI - Co-Creating an Expansive Health Care Learning System. AB - How should practices of co-creation be integrated into health professions education? Although co-creation permits a variety of interpretations, we argue that realizing a transformative vision of co-creation-one that invites professionals to genuinely reconsider the purposes, relationships, norms, and priorities of health care systems through new forms of collaborative thought and practice-will require radically rethinking existing approaches to professional education. The meaningful enactment of co-creative roles and practices requires health professionals and students to negotiate competing traditions, pressures, and expectations. We therefore suggest that the development of what we call an "expansive health care learning system" is crucial for supporting learners in meeting the challenges of establishing genuinely co-creative health care systems. PMID- 29168682 TI - How Should Organizations Promote Equitable Distribution of Benefits from Technological Innovation in Health Care? AB - Technological innovations typically benefit those who have good access to and an understanding of the underlying technologies. As such, technology-centered health care innovations are likely to preferentially benefit users of privileged socioeconomic backgrounds. Which policies and strategies should health care organizations adopt to promote equitable distribution of the benefits from technological innovations? In this essay, we draw on two important concepts-co creation (the joint creation of value by multiple parties such as a company and its customers) and digitalization (the application of new digital technologies and the ensuing changes in sociotechnical structures and relationships)-and propose a set of policies and strategies that health care organizations could adopt to ensure that benefits from technological innovations are more equitably distributed among all target populations, including resource-poor communities and individuals. PMID- 29168683 TI - Why Aren't Our Digital Solutions Working for Everyone? AB - The article explores a digital injustice that is occurring across the country: that digital solutions intended to increase health care access and quality often neglect those that need them most. It further shows that when it comes to digital innovation, health care professionals and technology companies rarely have any incentives to focus on underserved populations. Nevertheless, we argue that the technologies that are leaving these communities behind are the same ones that can best support them. The key is in leveraging these technologies with: (a) design features that accommodate various levels of technological proficiency (e literacy), (b) tech-enabled community health workers and navigators who can function as liaisons between patients and clinicians, and (c) analytics and customer relationship management tools that enable health care professionals and support networks to provide the right interventions to the right patients. Finally, we argue that community health care workers will need to be incentivized to play a larger role in building and adopting innovations targeting the underserved. PMID- 29168684 TI - Using Principles of Co-Production to Improve Patient Care and Enhance Value. AB - Unlike goods, which are concrete and easily quantified, services are intangible processes that are produced and consumed concurrently. Health care is a service that can encourage optimal health outcomes only through meaningful, collaborative partnerships between patients and clinicians. Co-production of health services can be used as a means to rethink how health care is delivered not only in the context of face-to-face encounters in which the benefits of working together are obvious, but also in designing systems that can improve patient care and enhance value. PMID- 29168685 TI - What Are the Professional, Political, and Ethical Challenges of Co-Creating Health Care Systems? AB - Co-creation is seen by many as a means of meeting the multiple challenges facing contemporary health care systems by involving institutions, professionals, patients, and stakeholders in new roles, relationships, and collaborative practices. While co-creation has the potential to positively transform health care systems, it generates a number of political and ethical challenges that should not be overlooked. We suggest that those involved in envisioning and implementing co-creation initiatives pay close attention to significant questions of equity, power, and justice and to the fundamental challenge of securing a common vision of the aims of and agendas for health care systems. While such initiatives present significant opportunities for improvement, they need to be viewed in light of their accompanying professional, political, and ethical challenges.

In 2015, after hundreds of therapies following her 2012 stroke, we were fortunate enough to find a therapist who understood the importance of compassion and empathy in clinical situations. Within a few months, my wife's physical, cognitive, mental, and emotional condition improved profoundly. As a photographer and author, I had been documenting her survival, recovery, and flourishing, and I was fortunate enough to recognize a moment of beauty and captured a single image that has since become my wife's inspiration for living. It is entitled "Healing Hands." PMID- 29168686 TI - How Co-Creation Helped Address Hierarchy, Overwhelmed Patients, and Conflicts of Interest in Health Care Quality and Safety. AB - Co-creation is health professionals' and systems' development of health care together with patients and families. Such collaborations yield an exchange of values, ideas, and priorities that can individualize care for each patient. Co creation has been discussed interchangeably with co-production and shared decision making; this article explores co-creation through the lens of quality improvement. Although there are barriers to co-creation including physician autonomy, patient overwhelm, and conflicts of interest, co-creation has been shown to promote patient engagement, peer learning, and improved outcomes. Further research is needed in co-creation for systems improvement. PMID- 29168688 TI - Long-term treatment with biosimilar epoetin-alpha (HX575) in hemodialysis patients with renal anemia: real-world effectiveness and safety in the MONITOR CKD5 study?. AB - AIMS: To assess real-world effectiveness and safety of intravenous (IV) HX575, a biosimilar epoetin-alpha, in hemodialysis (HD) patients. MATERIALS AND METHODS: This prospective, observational, pharmacoepidemiological study of adult HD patients treated with IV HX575 for renal anemia for up to 24 months was conducted in 114 centers in 10 European countries. Of 2,086 enrolled subjects (safety sample), 2,023 had >= 1 follow-up visit (effectiveness sample). RESULTS: Most (59.3%) patients were male, median age was 68 years. At enrollment, most (82.5%) had been treated with an erythropoiesis-stimulating agent, and 73.0% had adequate iron stores. At baseline, mean (+/- standard deviation) baseline hemoglobin (Hb) was 11.09 (+/- 1.14) g/dL and HX575 dose 106.5 (+/- 78.7) international units (IU)/kg/week; at month 24, Hb was 11.25 (+/- 1.19) g/dL and HX575 dose 113.0 (+/- 102.5) IU/kg/week. Variations in mean HX575 dose and Hb over the study were not statistically significant. As to safety, 140 patients (6.7%) experienced >= 1 adverse event; of these, 19 events (16 patients; 0.8%) were related to HX575 treatment, 148 (108 patients; 5.2%) were reported as serious, including 12 events in 11 patients (0.5%) stated to be related. No cases of anti-epoetin antibodies or pure red cell aplasia were reported. CONCLUSIONS: MONITOR-CKD5 confirmed the real-world effectiveness and safety profile of IV biosimilar HX575. HD patients treated for up to 24 months showed stable dosing patterns and Hb outcomes. The safety profile of HX575 is likewise comparable to reference epoetin-alpha.?. PMID- 29168689 TI - In-hospital prescriptions of secondary-prevention medications for post-acute coronary syndrome patients in South Korea?. AB - BACKGROUND: Optimal medical therapy and the management of cardiac risk factors are crucial for the secondary prevention of acute coronary syndrome (ACS). However, there have been reports on the underutilization of secondary-prevention medications for ACS. This study aimed to investigate adherence of in-hospital prescriptions to clinical practice guidelines for the secondary prevention of ACS using real-world data. MATERIALS AND METHODS: We collected information on ACS patients from national insurance claims data. The in-hospital prescriptions of secondary-prevention medications for post-ACS patients were analyzed. Prescription patterns were analyzed in relation to demographic, clinical, and institutional features. The utilization of five recommended medications and the factors influencing their use were investigated using logistic regression analysis. RESULTS: In total, 1,983 ACS patients were included in this analysis. The prescription rates of secondary-prevention medications were 94.4% for aspirin, 96.1% for P2Y12 inhibitors, 67.4% for beta-blockers, 63.5% for ACE inhibitors (ACEIs)/angiotensin receptor blockers (ARBs), and 86.5% for statins. Less than half of the patients were prescribed all five recommended medications. The prescription rate of secondary-prevention medications was lower in patients with unstable angina than in patients with myocardial infarction, particularly for beta-blockers and ACEIs/ARBs. The best predictive variable for determining the use of all five recommended medications was the type of ACS according to the results of the logistic regression analysis. CONCLUSIONS: In Korea, there is room for improvement in the prescription rates of secondary-prevention medications in post-ACS patients, particularly for beta-blockers and ACEIs/ARBs.?. PMID- 29168690 TI - Mitogen-activated protein kinase in gliosis and pilocytic astrocytoma. AB - Pilocytic astrocytoma (PA), featuring activation of the mitogen-activated protein kinase (MAPK) pathway, is the most common tumor of the pediatric central nervous system. However, it remains unknown whether MAPK activation is present in the reactive gliosis of non-neoplastic lesions. Therefore, we investigated the expression of MAPK in reactive gliosis associated with cavernous angiomas. Immunohistochemical expression and the extent of BRAF, ERK, p38, and JNK were investigated in 10 patients with gliosis surrounding cavernous angiomas (GS group) and 10 patients with PA (PA group). Evaluation of these parameters was scored as 0, none; 1, scarce; 2, moderate; 3, global. In the GS group, histopathologic features of PA (piloid cells, Rosenthal fibers, microcysts with eosinophilic granular bodies) were identified. Expression of ERK, and p38 was shown in all patients in the GS and PA group. Expression of BRAF was identified in 5 patients (50%) in the GS group and in 8 (80%) in the PA group. The mean score of BRAF expression in the PA group was significantly higher than that in the GS group (p = 0.019). Reactive gliosis may resemble PA in histological findings and MAPK activation. Therefore, PA could be indistinguishable from reactive gliosis with classic histopathologic and/or immunohistochemical methods.?.

AB - Cilia are small, antenna-like structures on the surface of eukaryotic cells that harbor a unique set of sensory proteins, including GPCRs and other membrane proteins. The transport of these proteins involves the BBSome, an eight-membered protein complex that is recruited to ciliary membranes by the G-protein Arl6. BBSome malfunction leads to Bardet-Biedl syndrome, a ciliopathy with severe consequences. Short ciliary targeting sequences (CTS) have been identified that trigger the transport of ciliary proteins. However, mechanistic studies that relate ciliary targeting to BBSome binding are missing. Here we used heterologously expressed BBSome subcomplexes to analyze the complex architecture and to investigate the binding of GPCRs and other receptors to the BBSome. A stable heterohexameric complex was identified that binds to GPCRs with interactions that only partially overlap with previously described CTS, indicating a more complex recognition than anticipated. Arl6*GTP does not affect these interactions, suggesting no direct involvement in cargo loading/unloading.

AB - Treatment for medulloblastoma, the most common malignant brain tumor in children, remains limited to surgical resection, radiation, and traditional chemotherapy; with long-term survival as low as 50-60% for Sonic Hedgehog (Shh)-type medulloblastoma. We have shown that the transcription factor Atonal homologue 1 (Atoh1) is required for Shh-type medulloblastoma development in mice. To determine whether reducing either Atoh1 levels or activity in tumors after their development is beneficial, we studied Atoh1 dosage and modifications in Shh-type medulloblastoma. Heterozygosity of Atoh1 reduced tumor occurrence and prolonged survival. We discovered tyrosine 78 of Atoh1 is phosphorylated by a Jak2-mediated pathway only in tumor-initiating cells and in human SHH-type medulloblastoma. Phosphorylation of tyrosine 78 stabilizes Atoh1, increases Atoh1's transcriptional activity, and is independent of canonical Jak2 signaling. Importantly, inhibition of Jak2 impairs tyrosine 78 phosphorylation and tumor growth in vivo. Taken together, inhibiting Jak2-mediated tyrosine 78 phosphorylation could provide a viable therapy for medulloblastoma. PMID- 29168695 TI - Tenofovir disoproxil fumarate as pre-exposure prophylaxis for HIV prevention in women with osteoporosis: a case report and review of the literature. AB - Pre-exposure prophylaxis (PrEP), using tenofovir disoproxil fumarate (TDF), can effectively prevent HIV acquisition. However, TDF can cause changes in bone mineral density (BMD). There is little information on the use of PrEP among patients with bone disease. We present a case report of a female with pre existing osteoporosis who was prescribed PrEP. Over the course of 9 months of consistent PrEP use, verified by dried blood spot testing, we report a lack of BMD changes on serial dual-emission X-ray absorptiometry scans in this patient. This case can inform PrEP care for patients with pre-existing bone disease. PMID- 29168693 TI - Zfp281 is essential for mouse epiblast maturation through transcriptional and epigenetic control of Nodal signaling. AB - Pluripotency is defined by a cell's potential to differentiate into any somatic cell type. How pluripotency is transited during embryo implantation, followed by cell lineage specification and establishment of the basic body plan, is poorly understood. Here we report the transcription factor Zfp281 functions in the exit from naive pluripotency occurring coincident with pre-to-post-implantation mouse embryonic development. By characterizing Zfp281 mutant phenotypes and identifying Zfp281 gene targets and protein partners in developing embryos and cultured pluripotent stem cells, we establish critical roles for Zfp281 in activating components of the Nodal signaling pathway and lineage-specific genes. Mechanistically, Zfp281 cooperates with histone acetylation and methylation complexes at target gene enhancers and promoters to exert transcriptional activation and repression, as well as epigenetic control of epiblast maturation leading up to anterior-posterior axis specification. Our study provides a comprehensive molecular model for understanding pluripotent state progressions in vivo during mammalian embryonic development. PMID- 29168696 TI - Correlation between entecavir penetration in peripheral blood mononuclear cells and HBV DNA decay during treatment of HBeAg-negative chronic hepatitis B. AB - BACKGROUND: Recently, due to its high effectiveness and tolerability, the treatment of chronic hepatitis B with entecavir became a standard practice. However, limited knowledge is currently available about its pharmacokinetic behaviour and intracellular disposition. Recently, our group reported an inverse correlation between entecavir plasma concentrations and the HBV DNA decay at the first and third month of treatment, respectively. In this paper we investigated the penetration of entecavir in peripheral blood mononuclear cells (PBMC) and in plasma, in order to evaluate the relationship between intracellular penetration and response, in a cohort of naive patients with hepatitis B e antigen (HBeAg) negative CHB. METHODS: Thirty-three patients were prospectively enrolled and gave written informed consent: the monitoring of clinical parameters (for example, HBV DNA, hepatitis B surface antigen [HBsAg], alanine aminotransferase) was carried out at the baseline and then monthly. Entecavir intra-PBMC and plasma trough concentrations were measured at 1 month of treatment, through a validated method based on liquid chromatography coupled with tandem mass spectrometry. RESULTS: While plasma entecavir analysis confirmed previous evidence of inverse correlation between drug concentrations and HBV DNA decrease after 3 months of treatment (r=-0.723; P<0.001), this correlation was not significant for intra PBMC concentrations. When the intracellular disposition ratio (intra-PBMC/plasma concentration ratio) was considered, it showed a direct and significant correlation with HBV DNA decay at the third month (r=0.485; P=0.004). CONCLUSIONS: These results suggest that the antiviral activity of entecavir is dependent on its intracellular uptake, thus resulting in lower plasma concentrations in patients who have a marked HBV DNA decrease during treatment. PMID- 29168697 TI - Direct contact membrane distillation for textile wastewater treatment: a state of the art review. AB - To meet surging water demands, water reuse is being sought as an alternative to traditional water resources. Direct contact membrane distillation (DCMD) has been increasingly studied in the past decade for its potential as an emerging cost effective wastewater treatment process and subsequent water reuse. This review presents a comprehensive overview of the current progress in the application of DCMD for textile wastewater treatment based on the available state of the art. There are already published review papers about the membrane distillation process, but the difference in the present work is that it focuses on the textile area, which consumes a lot of water and generates large amounts of wastewater, and still needs innovations in the sector. A review focused on the textile sector draws the attention of professionals to the problem and, consequently, to a solution. Current issues such as the influences of feed solution, membrane characteristics and membrane fouling and new insights are discussed. The main performance operating conditions and their effects on the separation process are given. Likewise, challenges associated with the influence of different dyes on the DCMD results are explained. This review also highlights the future research directions for DCMD to achieve successful implementation in the textile industry. PMID- 29168694 TI - The mechanism of variability in transcription start site selection. AB - During transcription initiation, RNA polymerase (RNAP) binds to promoter DNA, unwinds promoter DNA to form an RNAP-promoter open complex (RPo) containing a single-stranded 'transcription bubble,' and selects a transcription start site (TSS). TSS selection occurs at different positions within the promoter region, depending on promoter sequence and initiating-substrate concentration. Variability in TSS selection has been proposed to involve DNA 'scrunching' and 'anti-scrunching,' the hallmarks of which are: (i) forward and reverse movement of the RNAP leading edge, but not trailing edge, relative to DNA, and (ii) expansion and contraction of the transcription bubble. Here, using in vitro and in vivo protein-DNA photocrosslinking and single-molecule nanomanipulation, we show bacterial TSS selection exhibits both hallmarks of scrunching and anti scrunching, and we define energetics of scrunching and anti-scrunching. The results establish the mechanism of TSS selection by bacterial RNAP and suggest a general mechanism for TSS selection by bacterial, archaeal, and eukaryotic RNAP.

AB - The presence of organic pollutants in the environment is of major concern because of their toxicity, bio-accumulating tendency, threat to human life and the environment. It is a well-known fact that, these pollutants can damage nerves, liver, and bones and could also block functional groups of essential enzymes. Conventional methods for removing dissolved pollutants include chemical precipitation, chemical oxidation or reduction, filtration, ion-exchange, electrochemical treatment, application of membrane technology, evaporation recovery and biological treatment. Although all the pollutant treatment techniques can be employed, they have their inherent advantages and limitations. Among all these methods, adsorption process is considered better than other methods because of convenience, easy operation and simplicity of design. A fundamentally important characteristic of good adsorbents is their high porosity and consequent larger surface area with more specific adsorption sites. This paper presents a review of adsorption of different pollutants using activated carbon prepared from fly ash sources and the attendant environmental implications. Also, the ways of overcoming barriers to fly ash utilization together with regeneration studies are also discussed. PMID- 29168699 TI - Optimization of sulfate removal from wastewater using magnetic multi-walled carbon nanotubes by response surface methodology. AB - This paper reports a facile method for removal of sulfate from wastewater by magnetic multi-walled carbon nanotubes (MMWCNTs). Multi-walled carbon nanotubes and MMWCNTs were characterized by X-ray diffraction, Raman, transmission electron microscopy, Fourier transform infrared spectroscopy, and vibrating sample magnetometry. The results of the analysis indicated that MMWCNTs were synthesized successfully. The MMWCNTs can be easily manipulated in a magnetic field for the desired separation, leading to the removal of sulfate from wastewater. Response surface methodology (RSM) coupled with central composite design was applied to evaluate the effects of D/C (adsorbent dosage per initial concentration of pollutant (mgadsorbent/(mg/l)initial)) and pH on sulfate removal (%). Using RSM methodology, a quadratic polynomial equation was obtained, for removal of sulfate, by multiple regression analysis. The optimum combination for maximum sulfate removal of 93.28% was pH = 5.96 and D/C = 24.35. The experimental data were evaluated by the Langmuir and Freundlich adsorption models. The adsorption capacity of sulfate in the studied concentration range was 56.94 (mg/g). It was found out that the MMWCNTs could be considered as a promising adsorbent for the removal of sulfate from wastewater. PMID- 29168700 TI - Photodegradation of some brominated and phenolic micropollutants in raw hospital wastewater with CeO2 and TiO2 nanoparticles. AB - In this study, the degradations of 2,3,4,5,6-pentabromotoluene (PBT), 2,3,4,5,6 pentabromoethyl benzene (PBEB), triclosan (TCS) and gemfibrozil (GFZ) in raw hospital wastewater were investigated with cerium (IV) oxide and titanium (IV) oxide nanoparticles considering the mechanisms of adsorption, photolysis, and photocatalysis with UV-C lamps. The effects of nano-CeO2 and nano-TiO2 concentrations, irradiation times, UV light powers and hospital wastewater pH on the photodegradation yields of micropollutants namely PBT, PBEB, TCS and GFZ were investigated throughout photocatalysis. The nano-TiO2 produced had an anatase phase with crystalline shape with a surface area of 205 m2 g-1 and an average size of 11.50 nm. The CeO2 nanoparticles had a spherical shape with a higher surface area (302 m2 g-1) than that of TiO2 and a lower average size (8.11 nm). It was found that the removals of PBT, PBEB, TCS and GFZ with adsorption (5.7% 17.1%) and photolysis (9.0%-15.9%) were not significant for both nanoparticles. The photodegradation of PBT (92%), PBEB (90%), TCS (97%) and GFZ (95%) with nano CeO2 gave better results than nano-TiO2 (90%, 87%, 94% and 93% for PBT, PBEB, TCS and GFZ, respectively) under optimum experimental conditions (0.50 g L-1 nano CeO2, 45 min irradiation time, 25 degrees C temperature, pH = 8.50, 210 W UV light power). Both nanoparticles were reused effectively after photo-removals of the micropollutants from the hospital wastewater. The lowest photodegradation yields were 80%, 78%, 75% and 74% for TCS, GFZ, PBT and PBEB, respectively, with nano-TiO2 after six sequential treatments. The lowest photodegradation yields were 86%, 83%, 80% and 79% for the same micropollutants, respectively, with nano CeO2 after six sequential treatments. The cost to treat 1 m3 raw hospital wastewater were 8.70 ? and 2.28 ?, for the photocatalytic treatments with nano TiO2 and nano-CeO2, respectively. PMID- 29168701 TI - Wastewater pond systems using chemical precipitation (fellings dams): state of the art in Sweden. AB - Chemical precipitation in wastewater stabilization ponds - in Scandinavia called fellings dams - has been in operation for more than 50 years. Slaked lime and aluminium salts are the most common chemicals used for precipitation. Long and narrow forms of the ponds and a detention time of at least 5 days have shown, even at a low water temperature and below an ice cover, to produce an average effluent quality of 70 mg CODCr/l, 0.2 mg Tot-P/l, 20 mg Tot-N/l (CODCr: chemical oxygen demand; Tot-P: total phosphorus; Tot-N: total nitrogen) and low levels of pathogenic bacteria. The systems use low amounts of energy and no wastewater is by-passed at the plants. Fellings dams have recently been tried to support overloaded wastewater collection systems. PMID- 29168702 TI - The flocculation mechanism and treatment of oily wastewater by flocculation. AB - In the present study, the performance of compound flocculants composed of different concentrations of polyaluminum chloride (PAC) and cationic polyacrylamide (CPAM), the influencing mechanism of the flocculation process and the effects of temperature, settling time, and speed and time of stirring were investigated. The results show that the poor water quality with high concentrations of oil, suspended solids (SS) and polymer greatly increases the oily wastewater emulsion stability and the difficulty of the flocculation treatment process. The compound flocculant in oily wastewater treatment can achieve best results at optimum conditions of temperature 45 degrees C, settling time 60 min, and two stirring stages, 250 r.min-1 for 3 min followed by 100 r.min 1 for 7 min. At the PAC dosage of 80 mg.L-1 and the CPAM dosage of 0.8 mg.L-1, the turbidity of oily wastewater is reduced from 153.8 NTU to 11.2 NTU, and the turbidity removal rate reaches 92.69%. Through further measurements, oil content and SS content are less than 10 mg.L-1, which meets the requirement of the Daqing oilfield re-injection standard. PMID- 29168703 TI - Use of methyl esterified eggshell membrane for treatment of aqueous solutions contaminated with anionic sulfur dye. AB - The present study assessed the adsorption of an anionic dye (sulfur blue) by methyl-esterified eggshell membrane (MESM), a low-cost and abundant material from waste. Adsorption kinetics were investigated using parameters such as pH, contact time, initial dye concentration, solution temperature, dosage of adsorbent, and particle size of adsorbent. After methyl esterification, the specific surface area significantly increased and the negative surface charge of the eggshell membrane changed to positive for all pH values, which increased the sulfur dye sorption capacity. The optimal conditions for sorption of sulfur dye onto MESM resulted in >98% removal and were as follows: <35 MUm particle size, pH 8, 20 min contact time and 313 K temperature. In this respect, 0.68-0.73 dry weight mg/L sulfur dye was adsorbed per 1 mg/L MESM. The Langmuir adsorption capacity for sulfur dye was 187.6 mg/g. In addition, sulfur removal was spontaneous and uptake was endothermic. MESM is an inexpensive and effective adsorbent. PMID- 29168704 TI - Extracellular polymeric substance production in high rate algal oxidation ponds. AB - Integrated algal pond systems (IAPSs) combine anaerobic and aerobic bioprocesses to affect sewage treatment. The present work describes the isolation and partial characterisation of soluble extracellular polymeric substances (EPSs) associated with microalgal bacterial flocs (MaB-flocs) generated in high rate algal oxidation ponds (HRAOPs) of an IAPS treating domestic sewage. Productivity and change in MaB-flocs concentration, measured as mixed liquor suspended solids (MLSS) between morning (MLSSAM) and evening (MLSSPM) were monitored and the substructure of the MaB-flocs matrix examined by biochemical analysis and Fourier transform infrared spectroscopy (FT-IR). Results show that MaB-flocs from HRAOPs are assemblages of microorganisms produced as discrete aggregates as a result of microbial EPS production. Formation and accumulation of the EPS was stimulated by light. Analysis by FT-IR revealed characteristic carbohydrate enrichment of these polymeric substances. In contrast, FT-IR spectra of EPSs from dark-incubated MaB flocs confirmed that these polymers contained increased aliphatic and aromatic functionalities relative to carbohydrates. These differences, it was concluded, were due to dark-induced transition from phototrophic to heterotrophic metabolism. The results negate microalgal cell death as a contributor to elevated chemical oxygen demand of IAPS treated water. PMID- 29168705 TI - Study on COD removal mechanism and reaction kinetics of oilfield wastewater. AB - The chemical oxygen demand (COD) removal mechanism and reaction kinetics were mainly studied in the treatment of oilfield oily sewage containing polymer by three-dimensional electrode reactor. The results proved that the residual active oxides O3, H2O2, *OH and active chlorine in the system of electrochemical reaction could be effectively detected, and the COD removal mechanism was co oxidation of active oxides; Under these experimental conditions: the electrolysis current of 6 A, surface/volume ratio of 6/25(cm2.L-1), the reaction time of 50 min, the CODcr of treated sewage was no more than 50 mg.L-1; the removal reaction of COD conformed to apparent second-order reaction kinetic model, the correlation coefficient R2 was 0.9728, and the apparent reaction rate constant was k = 3.58 * 10-4 (L.min-1.mg-1.m-2). To reach the goal, the CODcr was no more than 50 mg.L-1 in treated sewage, and the theory minimum processing time was 45.73 min. The verification of experimental results was consistent with kinetic equations. PMID- 29168706 TI - Using terrestrial laser scanning in inventorying of a hybrid constructed wetland system. AB - The goal of this paper was to evaluate the possibility of using terrestrial laser scanning (TLS) for inventorying of a hybrid constructed wetland (CW) wastewater treatment plant. The object under study was a turtle-shaped system built in 2015 in Eastern Poland. Its main purpose is the treatment of wastewater from the Museum and Education Centre of Polesie National Park. The study showed that the CW system had been built in compliance with the technical documentation, as differences between values obtained from the object and those given in the design project (max. +/- 20 cm for situation and +/-5 cm for elevation) were within the range defined by the legislator. It was also shown that the results were sufficiently precise to be used for as-built surveying of the aboveground elements of the CW system. The TLS technique can also be employed to analyse quantitative changes in object geometry arising during long-term use (e.g. landmass slides or erosion), the identification of which can help in selecting the hot-spots at risk of damage and thus restore the object to its original state as well as prevent new changes. PMID- 29168707 TI - Properties of vanadium-loaded iron sorbent after alkali regeneration. AB - The aim of this research was to investigate the regeneration and reuse of a commercial granular iron sorbent (mainly goethite) when used in vanadium removal. A regeneration rate of 3 M NaOH was the highest (85%) achieved, followed by 2 M NaOH (79%) and 1 M NaOH (68%). The breakthrough curves show that the regenerated material can be reused. The BET (Brunauer-Emmett-Teller) surface area increased by 35-38% and the total pore volume increased by 123-130% as a consequence of NaOH treatment. The results indicated that sodium hydroxide could be used for the regeneration of iron sorbent although the regeneration was incomplete. This may be explained by the fact that vanadium diffusion into pores is a significant sorption mechanism in addition to complex formation with surface functional groups. As a consequence, vanadium desorbability from pores is not as effective as the regeneration of surface sites. X-ray photoelectron spectroscopy analyses confirmed a very low vanadium content on the surface of the NaOH-treated iron sorbent. PMID- 29168708 TI - Preparation of magnetic carbon/Fe3O4 supported zero-valent iron composites and their application in Pb(II) removal from aqueous solutions. AB - Nanoscale zero-valent iron (NZVI) was first assembled on magnetic carbon/Fe3O4 (CM) with a combination of hydrothermal and liquid phase reduction methods. The novel NZVI@CM magnetic nanocomposites have the merits of large surface area, unique magnetic property, low cost and environmental friendliness. They can be used for Pb(II) removal in aqueous solution. The materials were characterized by using transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), vibrating sample magnetometry (VSM), X-ray photoelectron spectroscopy (XPS) and Brunauer-Emmett-Teller (BET) adsorption. The various parameters, such as reaction time, dosage of catalyst, solution pH and acid ions concentrations were studied. The removal efficiency of Pb(II) can be obviously increased by the combination of appropriate CM and NZVI. The removal efficiency of Pb(II) is 99.7% by using 60 mg of NZVI@CM at pH 7. The kinetics study indicates that the Pb(II) removal accords to pseudo-second-order kinetics model. PMID- 29168710 TI - A soil column study to evaluate treatment of trace elements from saline industrial wastewater. AB - Industrial wastewater from the flue gas desulfurization (FGD) process is characterized by the presence of trace elements of concern, such as selenium (Se) and boron (B) and relatively high salinity. To simulate treatment that FGD wastewater undergoes during transport through soils in subsurface treatment systems, a column study (140-d duration) was conducted with native Kansas soil and saline FGD wastewater, containing high Se and B concentrations (170 MUg/L Se and 5.3 mg/L B) and negligible arsenic (As) concentration (~1.2 MUg/L As). Se, B, and As, and dissolved organic carbon concentrations and organic matter spectroscopic properties were measured in the influent and outflow. Influent Se concentrations were reduced by only ~half in all treatments, and results suggest that Se sorption was inhibited by high salinity of the FGD wastewater. By contrast, relative concentrations (C/Co) of B in the outflow were typically <10%, suggesting that B sequestration may have been enhanced by higher salinity. Unexpected elevated As concentrations in the outflow (at >150 MUg/L in the treatment with labile organic carbon addition) suggest that soils not previously known to be geogenic arsenic sources have the potential to release As to groundwater in the presence of high salinity wastewater and under reducing conditions. PMID- 29168709 TI - Isotopic fractionation of particulate organic matter and its biogeochemical implication in the littoral zone of Lake Taihu, China. AB - Signatures of stable isotope ratios have previously been used to trace the source and transport of particulate organic matter (POM) in freshwater and marine ecosystems. In this study, water columns were collected at 22 sites in the littoral zone of Lake Taihu in 2014 to investigate the distribution and concentration of nutrients and the stable isotope signatures of POM, and their potential interrelation. Generally, mean concentration of nitrogen forms (NH4+-N) showed substantial variation, probably because they had received large amounts of wastewater from various local industrial enterprises. Source analysis by stable carbon and nitrogen isotopic ratios showed that the main POM sources were phytoplankton. Contrasting correlations were obtained between delta15N and N concentrations in effluent river mouths when compared with influent river mouths. In effluent river mouths, there was a significant positive correlation between delta15N and nitrogen concentration (total nitrogen and ammonia-nitrogen), in contrast with the negative correlation in influent river mouths. According to these results, more factors should be taken into consideration when stable carbon and nitrogen isotopes of POM are used to assess the feeding relationship between consumers and prey, as well as the energy flow pathways that support the lake pelagic food webs. PMID- 29168711 TI - Separation of emulsified crude oil in saline water by flotation with micro- and nanobubbles generated by a multiphase pump. AB - The flocculation-column flotation with hydraulic loading (HL, >10 m h-1) was studied for the treatment of oil-in-water emulsions containing 70-400 mg L-1 (turbidity = 70-226 NTU) of oil and salinity (30 and 100 g L-1). A polyacrylamide (Dismulgan, 20 mg L-1) flocculated the oil droplets, using two floc generator reactors, with rapid and slow mixing stages (head loss = 0.9 to 3.5 bar). Flotation was conducted in two cells (1.5 and 2.5 m) with microbubbles (MBs, 5-80 MUm) and nanobubbles (NBs, 50-300 nm diameter, concentration of 108 NBs mL-1). Bubbles were formed using a centrifugal multiphase pump, with optimized parameters and a needle valve. The results showed higher efficiency with the taller column reducing the residual oil content to 4 mg L-1 and turbidity to 7 NTU. At high HL (27.5 m h-1), the residual oil concentrations were below the standard emission (29 mg L-1), reaching 18 mg L-1. The best results were obtained with high concentration of NBs (apart from the bigger bubbles). Mechanisms involved appear to be attachment and entrapment of the NBs onto and inside the flocs. Thus, the aggregates were readily captured, by bigger bubbles (mostly MBs) aiding shear withstanding. Advantages are the small footprint of the cells, low residence time and high processing rate. PMID- 29168712 TI - Adsorption of Congo red dye onto antimicrobial terephthaloyl thiourea cross linked chitosan hydrogels. AB - Adsorption capacity of three antimicrobial terephthaloyl thiourea cross-linked chitosan hydrogels for Congo red dye removal from its aqueous solution has been investigated for the first time in this work. These hydrogels were prepared by reacting chitosan with various amounts of terephthaloyl diisothiocyanate cross linker. The effect of the hydrogel structural variations and several dye adsorption processing parameters to achieve the best adsorption capacity were investigated. The hydrogels' structural variations were obtained by varying their terephthaloyl thiourea moieties content. The processing variables included initial concentration of the dye solution, temperature and time of exposure to the dye. The adsorption kinetics and isotherms showed that the sorption processes were better fitted by the pseudo-second-order equation and the Langmuir equation, respectively. On the basis of the Langmuir analysis Congo red dye gave the maximum sorption capacity of 44.248 mg/g. The results obtained confirmed that the sorption phenomena are most likely to be controlled by chemisorption process. The adsorption reaction was endothermic and spontaneous according to the calculated results of adsorption thermodynamics. PMID- 29168714 TI - Evaluation of nutrient retention in vegetated filter strips using the SWAT model. AB - Nutrient fluxes in stream basins need to be controlled to achieve good water quality status. In stream basins with intensive agricultural activities, nutrients predominantly come from diffuse sources. Therefore, best management practices (BMPs) are increasingly implemented to reduce nutrient input to streams. The objective of this study is to evaluate the impact of vegetated filter strip (VFS) application as an agricultural BMP. For this purpose, SWAT is chosen, a semi-distributed water quality assessment model that works at the watershed scale, and applied on the Nif stream basin, a small-sized basin in Western Turkey. The model is calibrated with an automated procedure against measured monthly discharge data. Nutrient loads for each sub-basin are estimated considering basin-wide data on chemical fertilizer and manure usage, population data for septic tank effluents and information about the land cover. Nutrient loads for 19 sub-basins are predicted on an annual basis. Average total nitrogen and total phosphorus loads are estimated as 47.85 t/yr and 13.36 t/yr for the entire basin. Results show that VFS application in one sub-basin offers limited retention of nutrients and that a selection of 20-m filter width is most effective from a cost-benefit perspective. PMID- 29168713 TI - Recovery of nutrients from digested sludge as struvite with a combination process of acid hydrolysis and Donnan dialysis. AB - In this study, the effects of the combination of acid hydrolysis and Donnan dialysis on the high-quality struvite production from digested sewage sludge were examined. The Box-Behnken design was applied in the hydrolysis using oxalic acid for the optimization of the conditions that affect the nutrients and metal release from digested sludge. An optimal condition was obtained at oxalic acid 0.5 M, acid/sludge ratio (mL/g) 10/1, and reaction time 60 min. The separation of the metals from hydrolyzed sludge liquid was carried out with the Donnan dialysis using a Nafion 117 cation exchange membrane. At the end of the 4 hours of operating time, the recovery values for Zn, K, Na, Mg, Fe, and Al were obtained as 67.9%, 62.1%, 57.6%, 39.4%, 5.3%, and 2.5%, respectively. The produced struvite meets the legal limits for fertilizer use in terms of Cd, Cu, Ni, Pb, Zn, Hg, and Cr content specified by Turkish regulations. A high Ca/Mg molar ratio and the presence of K, Na, and Al affected the efficiency of struvite crystallization. The use of oxalic acid resulted in low Ca release, and the metal ions that affect struvite purity were eliminated using Donnan dialysis. PMID- 29168715 TI - Emission of hydrogen sulfide (H2S) at a waterfall in a sewer: study of main factors affecting H2S emission and modeling approaches. AB - Hydrogen sulfide (H2S) represents one of the main odorant gases emitted from sewer networks. A mathematical model can be a fast and low-cost tool for estimating its emission. This study investigates two approaches to modeling H2S gas transfer at a waterfall in a discharge manhole. The first approach is based on an adaptation of oxygen models for H2S emission at a waterfall and the second consists of a new model. An experimental set-up and a statistical data analysis allowed the main factors affecting H2S emission to be studied. A new model of the emission kinetics was developed using linear regression and taking into account H2S liquid concentration, waterfall height and fluid velocity at the outlet pipe of a rising main. Its prediction interval was estimated by the residual standard deviation (15.6%) up to a rate of 2.3 g H2S.h-1. Finally, data coming from four sampling campaigns on sewer networks were used to perform simulations and compare predictions of all developed models.

AB - The mechanism of byproduct formation and oxidation pathway of bisphenol A (BPA) during ozonation process have been compared under acidic, neutral and alkaline conditions at an applied ozone dose of 5.3 mg.L-1 min-1. Alkaline conditions promoted the fastest removal and the pseudo first-order reaction rate constant was calculated as 0.15 min-1. Complete removal under alkaline conditions (after 30 minutes of reaction time) was achieved with 1.59 mg ozone per mg BPA and 52% mineralization was achieved at 6.04 mg ozone application per mg total organic carbon (after 90 minutes of reaction time). Hydroxyl radical dominated degradation pathway (pH 10) resulted with opening of ring-structured products into Heptanoic acid, methyl ester. Sixty per cent BPA removal occurred under acidic conditions where the ozone was dominant and formation of Cyclohexene-1 carboxylic acid, ethyl ester, Benzaldehyde, 4-hydroxy-3,5-dimethyl- and 2 Phenylbenzoquinone were evidenced. Despite the fact that complete removal was achieved under neutral conditions, mineralization was not remarkable and both hydroxyl radical and ozone-based degradation pattern was evidenced after the treatment.

AB - Cross-linked chitosan(C)/marble powder (M) composites with different weight ratio percentage (C100M0, C70M30, C50M50, and C30M70) were prepared from marble powder and chitosan and cross-linked using glutaraldehyde. The morphology and the surface area of the chitosan/marble powder composites were also characterized with a scanning electron microscope (SEM) and Micromeritics (ASAP 2020) BET (Brunauer, Emmett and Teller) instrument, respectively. To evaluate the adsorption behaviour of the chitosan/marble powder composites, 0.1 g adsorbent was added into 50 mL Diamozol Blue BRF %150 (C.I. Reactive Blue 221) solution with fixed concentrations (60 mg/L). At equilibrium, the adsorption capacity of C100M0, C70M30 and C50M50 for Dimozol Blue was about 27 mg/g and significantly greater than that of C30M70. C50M50 composite was more economical than C100M0 and C70M30 due to the higher marble powder content, and hence was selected as an adsorbent for the removal of Dimozol Blue from aqueous solution. The adsorption kinetics and equilibrium isotherms of Dimozol Blue onto the chitosan/marble powder composites from aqueous solution were investigated. The studies revealed that Dimozol Blue dye adsorption was described well by the pseudo-second-order and Freundlich isotherm models. The results of this study indicated the applicability of the chitosan/marble powder composites for removing industrial dyes from aqueous solution.

AB - A standard transmembrane pressure (TMP) step method has been used in membrane fouling assessment in tube ultrafiltration (UF) membrane system treating oil water (o/w) emulsion operated at constant TMP. Three flux reduction curve with different o/w concentration based on TMP variation were concluded by experiment, then, to describe fouling behavior and identify the occurrence of fouling in the so-called critical flux. Furthermore, sub-critical and super-critical flux experiment with a long time was determined, and zero rate of flux reduction (dF/dt) was never found during the whole trial period, indicating that critical flux in o/w UF process with its strict definition could not be defined in this paper. However, quasi-critical flux exists, under which the pollution rate was very slow. Moreover, a high-efficiency four steps cleaning method: mechanic scraping, pure water wash, pure water reverse wash, and dosing cleaning, was explored. It concluded that critical flux in real o/w UF system determined by TMP step method can be used to predict long-term critical behavior with useful data on fouling propensity. PMID- 29168719 TI - Influence of ultrasound on the heterogeneous Fenton-like oxidation of acetic acid. AB - The main objective of this study is to investigate the effect of ultrasound on the heterogeneous Fenton-like oxidation of acetic acid, which is one of the most resistant carboxylic acids to oxidation. For this purpose, firstly, the degradation of acetic acid was examined by using ultrasound alone and the effects of different parameters such as: type of sonication system, ultrasonic power, and addition of H2O2 were investigated on the degradation of acetic acid. There was no chemical oxygen demand (COD) reduction in the presence of sonication alone. In the presence of the heterogeneous Fenton-like oxidation process alone, at 303 K, COD reduction reached only 7.1% after 2 h of reaction. However, the combination of the heterogeneous Fenton-like oxidation process with ultrasound increased the COD reduction from 7.1% to 25.5% after 2 h of reaction in an ultrasonic bath operated at 40 kHz, while the COD reduction only increased from 7.1% to 8.9% in the ultrasonic reactor operated at 850 kHz. This result indicates that the hybrid process of ultrasound and heterogeneous Fenton-like oxidation is a promising process to degrade acetic acid. PMID- 29168720 TI - Assessment of uncertainty in discrete fracture network modeling using probabilistic distribution method. AB - There have been widespread concerns about solute transport problems in fractured media, e.g. the disposal of high-level radioactive waste in geological fractured rocks. Numerical simulation of particle tracking is gradually being employed to address these issues. Traditional predictions of radioactive waste transport using discrete fracture network (DFN) models often consider one particular realization of the fracture distribution based on fracture statistic features. This significantly underestimates the uncertainty of the risk of radioactive waste deposit evaluation. To adequately assess the uncertainty during the DFN modeling in a potential site for the disposal of high-level radioactive waste, this paper utilized the probabilistic distribution method (PDM). The method was applied to evaluate the risk of nuclear waste deposit in Beishan, China. Moreover, the impact of the number of realizations on the simulation results was analyzed. In particular, the differences between the modeling results of one realization and multiple realizations were demonstrated. Probabilistic distributions of 20 realizations at different times were also obtained. The results showed that the employed PDM can be used to describe the ranges of the contaminant particle transport. The high-possibility contaminated areas near the release point were more concentrated than the farther areas after 5E6 days, which was 25,400 m2.

AB - A coagulation-flocculation process was applied to wastewater of paint and construction chemicals producing factory in Turkey. Ferric chloride was used as coagulant and several natural based materials, namely limestone, pumice, sepiolite, bentonite and mussel shell were used as flocculant aids. The effects of dosage of flocculant aids on the pH, color and electrical conductivity of wastewater were studied. The experimental results showed that the treatment with all substances was very effective. The pHs of treated wastewater were obtained in the range of 5-7 without needing pH adjustment process. Fifteen Pt-Co color values were obtained on average, which is similar to pure water clarity. The amount of solute in the wastewater was evaluated by the electrical conductivity values. According to the results, under the optimum treatment conditions, chemical oxygen demands were determined. As a result of the work, the cost of chemicals for the wastewater treatment processes has been reduced by about 90%.

AB - This study analyses the mobilization of total suspended solids (TSS) for different spatial distributions of sediment load located over the roadway surface of a full-scale street section physical model. At the sewer network outlet, flow discharges were measured and TSS pollutographs were determined with manual grab samples and inferred from turbidity records. In all the tests, the rain duration was 5 min and its averaged intensity was 101 mm/h. In addition, solids that were not washed off at the end of the experiments were collected from the street surface, gully pots and pipes and the mass balance error was checked. The experiments were configured to assess the influence of the initial load, spatial distribution method, distance from gully pot and distribution area dimensions on the TSS washoff. The study showed that sediment initial load and distribution cannot explain completely pollutant washoff processes because other variables such as the spatial rainfall distribution or the runoff depth also affect to the outlet pollutographs and system mass balances. PMID- 29168723 TI - Agro-ecological compensation of watershed based on emergy. AB - The paper aims at providing a framework to calculate the agro-eco-compensation standard based on the systems agro-ecological concept of embodied energy as emergy. We have proposed a calculation system of eco-compensation standard for sustainable agricultural development based on the convertibility between emergy and price. According to our calculation, the total energy of agricultural production in Yongding River Basin was 3.45 E + 16 Sej/ha (the unit emergy value, expressed in solar emergy joules per unit) in terms of the renewable resources, nonrenewable resources, material inputs, and service costs. The energy of renewable and nonrenewable resources was 1.59 E + 16 and 1.86E + 16 Sej/ha, respectively. The ESI (environmental sustainability index) of the study area was 0.1056, indicating that its agricultural production was in a seriously unsustainable condition. To realize the sustainable agricultural production in the watershed, the downstream governments should pay $21.81 M (Y135 million) approximately to upstream governments for water and soil conservation. The results of the present study suggested that the emergy-based calculation method of agro-eco-compensation standard is feasible to a certain degree. PMID- 29168724 TI - Ca removal and Mg recovery from flue gas desulfurization (FGD) wastewater by selective precipitation. AB - Selective removal of Ca and recovery of Mg by precipitation from flue gas desulfurization (FGD) wastewater has been investigated. Thermodynamic analysis of four possible additives, Na2CO3, Na2C2O4, NaF and Na2SO4, indicated that both carbonate and oxalate could potentially provide effective separation of Ca via precipitation from Mg in FGD wastewater. However, it was found experimentally that the carbonate system was not as effective as oxalate in this regard. The oxalate system performed considerably better, with Ca removal efficiency of 96% being obtained, with little Mg inclusion at pH 6.0 when the dosage was *1.4 the stoichiometric requirement. On this basis, the subsequent recovery process for Mg was carried out using NaOH with two-step precipitation. The product was confirmed to be Mg(OH)2 (using X-ray diffraction and thermo gravimetric analysis) with elemental analysis suggesting a purity of 99.3 wt.%.

AB - Surface-modified magnetic Ni2.33Fe alloy nanoparticles were prepared using a hydrothermal method. Thermogravimetric analysis (TG) and Fourier transform infrared spectroscopy (FTIR) tests demonstrated that the surface was successfully modified by sodium citrate. The surface-modified particles can be used for removing nickel ions from aqueous solution. The adsorption kinetics studies were performed and the pseudo-second-order kinetic model successfully described the kinetic data. The diffusion model indicated the adsorption was regulated by both surface and intraparticle diffusion processes. The Freundlich and Langmuir adsorption models were adopted for the mathematical description of adsorption equilibrium, and it was found that the experimental data fitted very well to the Freundlich model.

AB - Semi-intensive Indian Major Carp (IMC) culture was practised in polythene lined dugout ponds at the Aquacultural Farm of Indian Institute of Technology, Kharagpur, West Bengal for 3 consecutive years at three different stocking densities (S.D), viz., 20,000, 35,000 and 50,000 numbers of fingerlings per hectare of water spread area. Fingerlings of Catla, Rohu and Mrigal were raised at a stocking ratio of 4:3:3. Total ammonia nitrogen (TAN) value along with other fishpond water quality parameters was monitored at 1 day intervals to ensure a good water ecosystem for a better fish growth. Water exchange was carried out before the TAN reached the critical limit. Field data on TAN obtained from the cultured fishponds stocked with three different stocking densities were used to study the dynamics of TAN. A developed model used to study the nutrient dynamics in shrimp pond was used to validate the observed data in the IMC pond ecosystem. Two years of observed TAN data were used to calibrate the spreadsheet model and the same model was validated using the third year observed data. The manual calibration based on the trial and error process of parameters adjustments was used and several simulations were performed by changing the model parameters. After adjustment of each parameter, the simulated and measured values of the water quality parameters were compared to judge the improvement in the model prediction. Forward finite difference discretization method was used in a MS Excel spreadsheet to calibrate and validate the model for obtaining the TAN levels during the culture period. Observed data from the cultured fishponds of three different S.D were used to standardize 13 model parameters. The efficiency of the developed spreadsheet model was found to be more than 90% for the TAN estimation in the IMC cultured fishponds. PMID- 29168727 TI - A Supercluster of Neutralizing Epitopes at the Interface of Ricin's Enzymatic (RTA) and Binding (RTB) Subunits. AB - As part of an effort to engineer ricin antitoxins and immunotherapies, we previously produced and characterized a collection of phage-displayed, heavy chain-only antibodies (VHHs) from alpacas that had been immunized with ricin antigens. In our initial screens, we identified nine VHHs directed against ricin toxin's binding subunit (RTB), but only one, JIZ-B7, had toxin-neutralizing activity. Linking JIZ-B7 to different VHHs against ricin's enzymatic subunit (RTA) resulted in several bispecific antibodies with potent toxin-neutralizing activity in vitro and in vivo. JIZ-B7 may therefore be an integral component of a future VHH-based neutralizing agent (VNA) for ricin toxin. In this study, we now localize, using competitive ELISA, JIZ-B7's epitope to a region of RTB's domain 2 sandwiched between the high-affinity galactose/N-acetylgalactosamine (Gal/GalNAc) binding site and the boundary of a neutralizing hotspot on RTA known as cluster II. Analysis of additional RTB (n = 8)- and holotoxin (n = 4)-specific VHHs from a recent series of screens identified a "supercluster" of neutralizing epitopes at the RTA-RTB interface. Among the VHHs tested, toxin-neutralizing activity was most closely associated with epitope proximity to RTA, and not interference with RTB's ability to engage Gal/GalNAc receptors. We conclude that JIZ-B7 is representative of a larger group of potent toxin-neutralizing antibodies, possibly including many described in the literature dating back several decades, that recognize tertiary and possibly quaternary epitopes located at the RTA-RTB interface and that target a region of vulnerability on ricin toxin. PMID- 29168729 TI - The Mental Homologies of Mammals. Towards an Understanding of Another Mammals World View. AB - Mammals' mental homologies include that they look after their young, suckle and protect them; they acquire information about the world by learning. They have five types of sensory receptors and a brain to analyze the information and they feel: that is they are sentient. Mental homologies have been largely ignored by behavioural scientists since Darwin because of certain historical beliefs. This however has not been the case for people who have had to do with non-human mammals who have long recognized their mental similarities to humans. As a result, behavioural science has sponsored some inappropriate research (examples are given). The study of another mammal species epistemology, (knowledge and world view) requires a recognition of these mental homologies. The result of a 25 year multi-disciplinary study indicates that there are nine mammalian mental homologies which define mammals. These are discussed and reviewed and further mental aptitudes which logically follow from these are pointed out. A Conditional Anthropomorphic approach is proposed. By recognizing the body/mind, whole "being" homologies of mammals, we can advance in understanding other mammal species' and individual's epistemology (world view), and consequently better their welfare and enrich our own lives. PMID- 29168728 TI - Interference of HTLV-1 Tax Protein with Cell Polarity Regulators: Defining the Subcellular Localization of the Tax-DLG1 Interaction. AB - Human T cell leukemia virus (HTLV)-1 Tax (Tax) protein is very important in viral replication and cell transformation. Tax localizes in the nucleus and cytoplasm in association with organelles. Some activities of Tax depend on interactions with PDZ (PSD-95/Discs Large/Z0-1) domain-containing proteins such as Discs large protein 1 (DLG1) which is involved in cell polarity and proliferation. The DLG1 interaction results in a cytoplasmic co-localization pattern resembling vesicular aggregates, the nature of which is still unknown. To further explore the role of PDZ proteins in HTLV-1 cell transformation, we deeply investigated the Tax-DLG1 association. By fluorescence resonance energy transfer (FRET), we detected, for the first time, the direct binding of Tax to DLG1 within the cell. We showed that the interaction specifically affects the cellular distribution of not only DLG1, but also Tax. After studying different cell structures, we demonstrated that the aggregates distribute into the Golgi apparatus in spatial association with the microtubule-organizing center (MTOC). This study contributes to understand the biological significance of Tax-PDZ interactions. PMID- 29168730 TI - Comparative Proteomics Analyses of Pollination Response in Endangered Orchid Species Dendrobium Chrysanthum. AB - Pollination is a crucial stage in plant reproductive process. The self compatibility (SC) and self-incompatibility (SI) mechanisms determined the plant genetic diversity and species survival. D. chrysanthum is a highly valued ornamental and traditional herbal orchid in Asia but has been declared endangered. The sexual reproduction in D. chrysanthum relies on the compatibility of pollination. To provide a better understanding of the mechanism of pollination, the differentially expressed proteins (DEP) between the self pollination (SP) and cross-pollination (CP) pistil of D. chrysanthum were investigated using proteomic approaches-two-dimensional electrophoresis (2-DE) coupled with tandem mass spectrometry technique. A total of 54 DEP spots were identified in the two-dimensional electrophoresis (2-DE) maps between the SP and CP. Gene ontology analysis revealed an array of proteins belonging to following different functional categories: metabolic process (8.94%), response to stimulus (5.69%), biosynthetic process (4.07%), protein folding (3.25%) and transport (3.25%). Identification of these DEPs at the early response stage of pollination will hopefully provide new insights in the mechanism of pollination response and help for the conservation of the orchid species.

AB - In the last several decades, the genetic ability to taste the bitter compound, 6 n-propyltiouracil (PROP) has attracted considerable attention as a model for understanding individual differences in taste perception, and as an oral marker for food preferences and eating behavior that ultimately impacts nutritional status and health. However, some studies do not support this role. This review describes common factors that can influence the characterization of this phenotype including: (1) changes in taste sensitivity with increasing age; (2) gender differences in taste perception; and (3) effects of smoking and obesity. We suggest that attention to these factors during PROP screening could strengthen the associations between this phenotype and a variety of health outcomes ranging from variation in body composition to oral health and cancer risk. PMID- 29168733 TI - Single-Shot Detection of Neurotransmitters in Whole-Blood Samples by Means of the Heat-Transfer Method in Combination with Synthetic Receptors. AB - Serotonin is an important neurotransmitter that plays a major role in the pathogenesis of a variety of conditions, including psychiatric disorders. The detection of serotonin typically relies on high-performance liquid chromatography (HPLC), an expensive technique that requires sophisticated equipment and trained personnel, and is not suitable for point-of-care applications. In this contribution, we introduce a novel sensor platform that can measure spiked neurotransmitter concentrations in whole blood samples in a fast and low-cost manner by combining synthetic receptors with a thermal readout technique-the heat transfer method. In addition, the design of a miniaturized version of the sensing platform is presented that aims to bridge the gap between measurements in a laboratory setting and point-of-care measurements. This fully automated and integrated, user-friendly design features a capillary pumping unit that is compatible with point-of-care sampling techniques such as a blood lancet device (sample volume-between 50 uL and 300 uL). Sample pre-treatment is limited to the addition of an anti-coagulant. With this fully integrated setup, it is possible to successfully discriminate serotonin from a competitor neurotransmitter (histamine) in whole blood samples. This is the first demonstration of a point-of care ready device based on synthetic receptors for the screening of neurotransmitters in complex matrices, illustrating the sensor's potential application in clinical research and diagnosis of e.g., early stage depression.

AB - Yacon (Smallanthus sonchifolius Poepp.) leaves are a potentially rich source of bioactive compounds, such as phenolic acids and flavonoids. In this study, the effect of the extraction method (ohmic-assisted decoction (OH-DE) and decoction (DE)), yacon cultivar (red and white), and leaf age (young and old) on the quality/quantity of extracted phytochemicals were investigated. Extraction yield, energy consumption, total phenolic content (TPC), total flavonoid content (TFC), ABTS and DPPH radical scavenging activity, and ferric reducing antioxidant power (FRAP) were determined. Additionally, HPLC-DAD was used to identify the major individual phenolic and flavonoid compounds of yacon leaves. The results showed that a three-way interaction of process-variables (extraction method*yacon cultivar*age of leaves) influenced the extraction yield, TPC, TFC, ABTS, and DPPH radical scavenging activity, and FRAP, significantly (p < 0.05). However, energy consumption of the extraction process was only affected by method of extraction (p < 0.05) and was halved when OH-DE was applied as compared to DE alone. Additionally, the phytochemical quality of extracts was either improved or comparable when OH-DE was used for extraction. Also, it was shown that yacon leaves contained considerable amounts of caffeic acid, chlorogenic acid, ferrulic acid, myricetin, p-coumaric acid, and rutin, while leaves of the red cultivar had higher contents of each compound compared to leaves of the white cultivar. PMID- 29168735 TI - A Polar Initial Alignment Algorithm for Unmanned Underwater Vehicles. AB - Due to its highly autonomy, the strapdown inertial navigation system (SINS) is widely used in unmanned underwater vehicles (UUV) navigation. Initial alignment is crucial because the initial alignment results will be used as the initial SINS value, which might affect the subsequent SINS results. Due to the rapid convergence of Earth meridians, there is a calculation overflow in conventional initial alignment algorithms, making conventional initial algorithms are invalid for polar UUV navigation. To overcome these problems, a polar initial alignment algorithm for UUV is proposed in this paper, which consists of coarse and fine alignment algorithms. Based on the principle of the conical slow drift of gravity, the coarse alignment algorithm is derived under the grid frame. By choosing the velocity and attitude as the measurement, the fine alignment with the Kalman filter (KF) is derived under the grid frame. Simulation and experiment are realized among polar, conventional and transversal initial alignment algorithms for polar UUV navigation. Results demonstrate that the proposed polar initial alignment algorithm can complete the initial alignment of UUV in the polar region rapidly and accurately.

AB - Subclinical micronutrient deficiency in older adults is associated with chronic age-related diseases and adverse functional outcomes. In Germany, the older population is at risk of insufficient micronutrient intake, but representative studies on micronutrient status in old and very old adults are scarce. This study's objectives were to estimate the prevalence of subclinical vitamin D, folate, vitamin B12 and iron deficiencies among older adults, aged 65 to 93, from the KORA-Age study in Augsburg, Germany (n = 1079), and to examine associated predictors, using multiple logistic regression. Serum concentrations of 25 hydroxyvitamin D (25OHD), folate, vitamin B12, and iron were analyzed. The prevalence of subclinical vitamin D and vitamin B12 deficiencies were high, with 52.0% and 27.3% of individuals having low 25OHD (<50 nmol/L) and low vitamin B12 concentrations (<221 pmol/L), respectively. Furthermore, 11.0% had low iron (men <11.6 umol/L, women <9.0 umol/L) and 8.7% had low folate levels (<13.6 nmol/L). Common predictors associated with subclinical micronutrient deficiency included very old age, physical inactivity, frailty and no/irregular use of supplements. Subclinical micronutrient deficiency is a public health concern among KORA-Age participants, especially for vitamins D and B12. The predictors identified provide further rationale for screening high-risk subgroups and developing targeted public health interventions to tackle prevailing micronutrient inadequacies among older adults. PMID- 29168736 TI - Association between Vitamin Intake during Pregnancy and Risk of Small for Gestational Age. AB - Pregnancy increases the requirements of certain nutrients, such as vitamins, to provide nutrition for the newborn. The aim was to analyze the association between dietary intake of vitamins during pregnancy and risk of having a small for gestational age (SGA) newborn. A matched case-control study was conducted (518 cases and 518 controls of pregnant women) in Spain. Dietary vitamin intake during pregnancy was assessed using a validated food frequency questionnaire, categorized into quintiles. Odds ratios (ORs) and their 95% confidence intervals (CI) were estimated with conditional regression logistic models. A protective association was observed between maternal dietary intake of vitamins A and D and SGA. For vitamin B3 and B6, the observed protective effect was maintained after adjusting for potential confounding factors. For vitamin B9, we found only an effect in quintiles 3 and 4 (OR = 0.64; 95% CI, 0.41-1.00; OR = 0.58; 95% CI, 0.37-0.91). Protective effect for vitamin B12 was observed in 4th and 5th quintiles (OR = 0.61; 95% CI, 0.39-0.95; OR = 0.68; 95% CI, 0.43-1.04). No associations were detected between dietary intake of vitamins B2, E and C intake and SGA. Our results suggest a positive association between dietary vitamin intake during pregnancy and the weight of the newborn, although more studies are necessary and there could be a ceiling effect for higher intakes of some vitamins cannot be discarded.

AB - Cholera toxin B subunit (CTB) is a mucosal immunomodulatory protein that induces robust mucosal and systemic antibody responses. This well-known biological activity has been exploited in cholera prevention (as a component of Dukoral(r) vaccine) and vaccine development for decades. On the other hand, several studies have investigated CTB's immunotherapeutic potential in the treatment of inflammatory diseases such as Crohn's disease and asthma. Furthermore, we recently found that a variant of CTB could induce colon epithelial wound healing in mouse colitis models. This review summarizes the possible mechanisms behind CTB's anti-inflammatory activity and discuss how the protein could impact mucosal inflammatory disease treatment. PMID- 29168739 TI - Early or Late Feeding after ICU Admission? AB - The feeding of critically ill patients has recently become a controversial issue, as several studies have provided unexpected and contradictory results. Earlier beliefs regarding energy requirements in critical illness-especially during the initial phase-have been challenged. In the current review, we summarize existing evidence about fasting and the impact of early vs. late feeding on the sick organism's responses. The most important points are the non-nutritional advantages of using the intestine, and recognition that early endogenous energy production as an important player in the response must be integrated in the nutrient prescription. There is as of yet no bedside tool to monitor dynamics in metabolism and the magnitude of the endogenous energy production. Hence, an early "full-feeding strategy" exposes patients to involuntary overfeeding, due to the absence of an objective measure enabling the adjustment of the nutritional therapy. Suggestions for future research and clinical practice are proposed. PMID- 29168742 TI - Turning and Radius Deviation Correction for a Hexapod Walking Robot Based on an Ant-Inspired Sensory Strategy. AB - Abstract: In order to find a common approach to plan the turning of a bio inspired hexapod robot, a locomotion strategy for turning and deviation correction of a hexapod walking robot based on the biological behavior and sensory strategy of ants. A series of experiments using ants were carried out where the gait and the movement form of ants was studied. Taking the results of the ant experiments as inspiration by imitating the behavior of ants during turning, an extended turning algorithm based on arbitrary gait was proposed. Furthermore, after the observation of the radius adjustment of ants during turning, a radius correction algorithm based on the arbitrary gait of the hexapod robot was raised. The radius correction surface function was generated by fitting the correction data, which made it possible for the robot to move in an outdoor environment without the positioning system and environment model. The proposed algorithm was verified on the hexapod robot experimental platform. The turning and radius correction experiment of the robot with several gaits were carried out. The results indicated that the robot could follow the ideal radius and maintain stability, and the proposed ant-inspired turning strategy could easily make free turns with an arbitrary gait.

AB - The bone is one of the relevant target organs of heavy metals, and heavy metal toxicity is associated with several degenerative processes, such osteoporosis and bone mineral alterations, that could lead to fractures. We aimed to study a presumed relationship between bone density, evaluated by quantitative bone ultrasound (QUS), dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) and the dietary intake of cadmium, lead and mercury in healthy premenopausal women. A total of 158 healthy, non-smoking, premenopausal women were incorporated into the study. A validated food frequency questionnaire (FFQ) was administered to assess intake during the preceding seven days. The median predicted dietary cadmium intake among the 158 women studied was 25.29 MUg/day (18.62-35.00) and 2.74 MUg/kg body weight/week (b.w./w) (1.92 3.83). Dietary lead intake was 43.85 MUg/day (35.09-51.45) and 4.82 MUg/kg b.w./w (3.67-6.13). The observed dietary mercury intake was 9.55 MUg/day (7.18-13.57) and 1.02 MUg/kg b.w./w (0.71-1.48). Comparisons, in terms of heavy metal intake, showed no significant results after further adjusting for energy intake. No statistically significant correlations between heavy metal intake and the QUS, DXA and pQCT parameters were observed. Levels of dietary exposure of cadmium, lead and mercury were mostly within the recommendations. We did not find associations between the QUS, DXA and pQCT parameters and the dietary intake of the studied heavy metals in healthy premenopausal women. PMID- 29168741 TI - Dose-Dependent Effects of Oral Tyrosine Administration on Plasma Tyrosine Levels and Cognition in Aging. AB - The effects of tyrosine on plasma response and cognition in aging are unknown. We assessed the dose-dependent response to tyrosine administration in older adults in both plasma tyrosine concentrations and working memory performance. In this double blind randomized cross-over trial 17 older adults (aged 60-75 years) received a single administration of 100, 150, or 200 mg/kg body weight of tyrosine. For comparison, 17 young adults (aged 18-35 years) received a dose of 150 mg/kg body weight of tyrosine. Tyrosine plasma concentrations were determined before and 90, 120, 150, 180, 210, and 240 min after tyrosine intake. Working memory was assessed using the N-back task at 90 min after tyrosine administration. Older adults showed a dose-dependent increase in plasma tyrosine concentrations (p < 0.001), and the plasma response was higher than for young adults with the same dose (p < 0.001). Load-dependent working memory performance decreased with higher doses of tyrosine (p = 0.048), especially in older adults with greater dose-dependent plasma tyrosine responses (p = 0.035). Our results show an age-related increase in plasma tyrosine response, which was associated with a dose-dependent decline in cognitive functioning in older adults.

AB - The polyaniline/TiO2 (PANI/TiO2) composite photocatalysts were prepared by the in situ chemical oxidation of aniline (An) in the presence of TiO2 particles. For this purpose, photocatalysts with different amounts of PANI polymer were prepared and analysed. Fourier-transform infrared (FT-IR) spectroscopy and thermogravimetric (TG) analysis indicated successful synthesis of the PANI polymer and its conductivity was also determined. The micrographs of field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) were used to explain the impact of the aniline amount on the aggregation process during the synthesis of the composites. The smallest size of aggregates was obtained for the photocatalysts with 15% of PANI (15PANI/TiO2) due to the formation of homogenous PANI. The photocatalytic activity of studied PANI/TiO2 photocatalysts was validated by monitoring the discoloration and mineralization of Reactive Red azo dye (RR45) in wastewater. The 15PANI/TiO2 sample presented the highest photocatalytic efficiency under ultraviolet A (UVA) irradiation, in comparison to pure TiO2. This was explained by the formation of uniformly dispersed PANI on the TiO2 particles, which was responsible for the synergistic PANI-TiO2 effect. PMID- 29168743 TI - Synthesis and Anticandidal Activity Evaluation of New Benzimidazole-Thiazole Derivatives. AB - Azole-based antifungal agents constitute one of the important classes of antifungal drugs. Hence, in the present work, 12 new benzimidazole-thiazole derivatives 3a-3l were synthesized to evaluate their anticandidal activity against C.albicans, C.glabrata, C.krusei, and C.parapsilopsis. The structures of the newly synthesized compounds 3a-3l were confirmed by IR, 1H-NMR, 13C-NMR, and ESI-MS spectroscopic methods. ADME parameters of synthesized compounds 3a-3l were predicted by an in-slico study and it was determined that all synthesized compounds may have a good pharmacokinetic profile. In the anticandidal activity studies, compounds 3c and 3d were found to be the most active compounds against all Candida species. In addition, cytoxicity studies showed that these compounds are nontoxic with a IC50 value higher than 500 ug/mL. The effect of compounds 3c and 3d on the ergosterol level of C.albicans was determined by an LC-MS-MS method. It was observed that both compounds cause a decrease in the ergosterol level. A molecular docking study including binding modes of 3c to lanosterol 14alpha-demethylase (CYP51), a key enzyme in ergosterol biosynthesis, was performed to elucidate the mechanism of the antifungal action. The docking studies revealed that there is a strong interaction between CYP51 and the most active compound 3c. PMID- 29168745 TI - Interaction of Cholesterol with Perfringolysin O: What Have We Learned from Functional Analysis? AB - Cholesterol-dependent cytolysins (CDCs) constitute a family of pore-forming toxins secreted by Gram-positive bacteria. These toxins form transmembrane pores by inserting a large beta-barrel into cholesterol-containing membranes. Cholesterol is absolutely required for pore-formation. For most CDCs, binding to cholesterol triggers conformational changes that lead to oligomerization and end in pore-formation. Perfringolysin O (PFO), secreted by Clostridium perfringens, is the prototype for the CDCs. The molecular mechanisms by which cholesterol regulates the cytolytic activity of the CDCs are not fully understood. In particular, the location of the binding site for cholesterol has remained elusive. We have summarized here the current body of knowledge on the CDCs cholesterol interaction, with focus on PFO. We have employed sterols in aqueous solution to identify structural elements in the cholesterol molecule that are critical for its interaction with PFO. In the absence of high-resolution structural information, site-directed mutagenesis data combined with binding studies performed with different sterols, and molecular modeling are beginning to shed light on this interaction. PMID- 29168747 TI - Optimization of Dissolution Compartments in a Biorelevant Dissolution Apparatus Golem v2, Supported by Multivariate Analysis. AB - Biorelevant dissolution instruments represent an important tool for pharmaceutical research and development. These instruments are designed to simulate the dissolution of drug formulations in conditions most closely mimicking the gastrointestinal tract. In this work, we focused on the optimization of dissolution compartments/vessels for an updated version of the biorelevant dissolution apparatus-Golem v2. We designed eight compartments of uniform size but different inner geometry. The dissolution performance of the compartments was tested using immediate release caffeine tablets and evaluated by standard statistical methods and principal component analysis. Based on two phases of dissolution testing (using 250 and 100 mL of dissolution medium), we selected two compartment types yielding the highest measurement reproducibility. We also confirmed a statistically ssignificant effect of agitation rate and dissolution volume on the extent of drug dissolved and measurement reproducibility. PMID- 29168746 TI - Dissection of Resistance Genes to Pseudomonas syringae pv. phaseolicola in UI3 Common Bean Cultivar. AB - Few quantitative trait loci have been mapped for resistance to Pseudomonas syringae pv. phaseolicola in common bean. Two F2 populations were developed from the host differential UI3 cultivar. The objective of this study was to further characterize the resistance to races 1, 5, 7 and 9 of Psp included in UI3. Using a QTL mapping approach, 16 and 11 main-effect QTLs for pod and primary leaf resistance were located on LG10, explaining up to 90% and 26% of the phenotypic variation, respectively. The homologous genomic region corresponding to primary leaf resistance QTLs detected tested positive for the presence of resistance associated gene cluster encoding nucleotide-binding and leucine-rich repeat (NL), Natural Resistance Associated Macrophage (NRAMP) and Pentatricopeptide Repeat family (PPR) proteins. It is worth noting that the main effect QTLs for resistance in pod were located inside a 3.5 Mb genomic region that included the Phvul.010G021200 gene, which encodes a protein that has the highest sequence similarity to the RIN4 gene of Arabidopsis, and can be considered an important candidate gene for the organ-specific QTLs identified here. These results support that resistance to Psp from UI3 might result from the immune response activated by combinations of R proteins, and suggest the guard model as an important mechanism in pod resistance to halo blight. The candidate genes identified here warrant functional studies that will help in characterizing the actual defense gene(s) in UI3 genotype. PMID- 29168749 TI - Positron Annihilation and Complementary Studies of Copper Sandblasted with Alumina Particles at Different Pressures. AB - Positron annihilation spectroscopy and complementary methods were used to detect changes induced by sandblasting of alumina particles at different pressures varying from 1 to 6 bar in pure well-annealed copper. The positron lifetime measurements revealed existence of dislocations and vacancy clusters in the adjoined surface layer. The presence of retained alumina particles in the copper at the depth below 50 um was found in the SEM pictures and also in the annihilation line shape parameter profiles measured in the etching experiment. The profiles show us that the total depth of damaged zones induced by sandblasting of alumina particles ranges from 140 um up to ca. 800 um and it depends on the applied pressure. The work-hardening of the adjoined surface layer was found in the microhardness measurements at the cross-section of the sandblasted samples. PMID- 29168748 TI - Variety and Dynamics of Proteoforms in the Human Proteome: Aspects of Markers for Hepatocellular Carcinoma. AB - We have previously developed an approach, where two-dimensional gel electrophoresis (2DE) was used, followed by sectional analysis of the whole gel using high-resolution nano-liquid chromatography-mass spectrometry (ESI LC MS/MS). In this study, we applied this approach on the panoramic analysis of proteins and their proteoforms from normal (liver) and cancer (HepG2) cells. This allowed us to detect, in a single proteome, about 20,000 proteoforms coded by more than 4000 genes. A set of 3D-graphs showing distribution of these proteoforms in 2DE maps (profiles) was generated. A comparative analysis of these profiles between normal and cancer cells showed high variability and dynamics of many proteins. Among these proteins, there are some well-known features like alpha-fetoprotein (FETA) or glypican-3 (GPC3) and potential hepatocellular carcinoma (HCC) markers. More detailed information about their proteoforms could be used for generation of panels of more specific biomarkers. PMID- 29168750 TI - Deep Convolutional Neural Network-Based Early Automated Detection of Diabetic Retinopathy Using Fundus Image. AB - The automatic detection of diabetic retinopathy is of vital importance, as it is the main cause of irreversible vision loss in the working-age population in the developed world. The early detection of diabetic retinopathy occurrence can be very helpful for clinical treatment; although several different feature extraction approaches have been proposed, the classification task for retinal images is still tedious even for those trained clinicians. Recently, deep convolutional neural networks have manifested superior performance in image classification compared to previous handcrafted feature-based image classification methods. Thus, in this paper, we explored the use of deep convolutional neural network methodology for the automatic classification of diabetic retinopathy using color fundus image, and obtained an accuracy of 94.5% on our dataset, outperforming the results obtained by using classical approaches. PMID- 29168752 TI - Enological Tannin Effect on Red Wine Color and Pigment Composition and Relevance of the Yeast Fermentation Products. AB - Enological tannins are widely used in the winemaking process either to improve different wine characteristics (color stability, among others) or to compensate for low tannin levels. In this work, the influence of the addition of two different enological tannins, mainly composed of hydrolysable (ellagitannins) and condensed tannins, on the evolution of color and pigment composition of two different types of model systems containing the five main grape anthocyanins was studied. In addition, the effect of the addition of an enological tannin on the color and pigment composition of red wines made from Vitis vinifera L. cv Tempranillo grapes was also studied by high-performance liquid chromatography with diode array detection coupled to mass spectrometry (HPLC-DAD-MS). Results showed that, in model systems, the addition of the enological tannin favored the formation of anthocyanin-derived pigments, such as A-type and B-type vitisins and flavanol-anthocyanin condensation products, provided that the yeast precursors were previously supplied. Moreover, model systems containing the enological tannins were darker and showed higher values of chroma at the end of the study than control ones. The higher formation of these anthocyanin-derived pigments was also observed in the red wines containing the enological tannin. Moreover, these wine also showed lower lightness (L*) values and higher chroma (C*ab) values than control wines, indicating a higher stabilization of color. PMID- 29168751 TI - A Strategy for Preparative Separation of 10 Lignans from Justicia procumbens L. by High-Speed Counter-Current Chromatography. AB - Ten compounds, including three lignan glycosides and seven lignans, were purified from Justicia procumbens L. in 8 h using an efficient strategy based on high speed counter-current chromatography (HSCCC). The two-phase solvent system composed of petroleum-ethyl acetate-methanol-H2O (1:0.7:1:0.7, v/v) was firstly employed to separate the crude extract (320 mg), from which 19.3 mg of justicidin B (f), 10.8 mg of justicidin A (g), 13.9 mg of 6'-hydroxyjusticidin C (h), 7.7 mg of justicidin E (i), 6.3 mg of lignan J1 (j) were obtained with 91.3 mg of enriched mixture of compounds a-e. The enriched mixture (91.3 mg) was further separated using the solvent system consisting of petroleum-ethyl acetate-methanol H2O (3:3.8:3:3.8, v/v), yielding 12.1 mg of procumbenoside E (a); 7.6 mg of diphyllin-1-O-beta-d-apiofuranoside (b); 7.4 mg of diphyllin (c); 8.3 mg of 6' hydroxy justicidin B (d); and 7.9 mg of diphyllin acetyl apioside (e). The purities of the 10 components were all above 94%, and their structures were identified by NMR and ESI-MS spectra. The results demonstrated that the strategy based on HSCCC for the separation of lignans and their glycosides was efficient and rapid. PMID- 29168753 TI - Recyclable Magnetic Titania Nanocomposite from Ilmenite with Enhanced Photocatalytic Activity. AB - Using ilmenite as a raw material, iron was converted into Fe3O4 magnetic fluid, which further was combined with titanium filtrate by a solvothermal method. Finally Fe3O4/TiO2 nanocomposites with the uniform size of 100-200 nm were prepared. This approach uses rich, inexpensive ilmenite as a titanium and iron source, which effectively reduces the production cost. The crystal structure, chemical properties and morphologies of the products were characterized by SEM, TEM, XRD, FTIR, BET, UV-Vis, XPS and VSM. The novel photocatalyst composed of face-centered cubic Fe3O4 and body-centered tetragonal anatase-TiO2 exhibits a spherical shape with porous structures, superparamagnetic behavior and strong absorption in the visible light range. Using the degradation reaction of Rhodamine B (RhB) to evaluate the photocatalytic performance, the results suggest that Fe3O4/TiO2 nanocomposites exhibit excellent photocatalytic activities and stability under visible light and solar light. Moreover, the magnetic titania nanocomposites displayed good magnetic response and were recoverable over several cycles. Based on the trapping experiments, the main active species in the photocatalytic reaction were confirmed and the possible photocatalytic mechanism of RhB with magnetic titania was proposed. The enhanced photocatalytic activity and stability, combined with excellent magnetic recoverability, make the prepared nanocomposite a potential candidate in wastewater purification. PMID- 29168754 TI - A Bioinformatic Pipeline for Monitoring of the Mutational Stability of Viral Drug Targets with Deep-Sequencing Technology. AB - The efficient development of antiviral drugs, including efficient antiviral small interfering RNAs (siRNAs), requires continuous monitoring of the strict correspondence between a drug and the related highly variable viral DNA/RNA target(s). Deep sequencing is able to provide an assessment of both the general target conservation and the frequency of particular mutations in the different target sites. The aim of this study was to develop a reliable bioinformatic pipeline for the analysis of millions of short, deep sequencing reads corresponding to selected highly variable viral sequences that are drug target(s). The suggested bioinformatic pipeline combines the available programs and the ad hoc scripts based on an original algorithm of the search for the conserved targets in the deep sequencing data. We also present the statistical criteria for the threshold of reliable mutation detection and for the assessment of variations between corresponding data sets. These criteria are robust against the possible sequencing errors in the reads. As an example, the bioinformatic pipeline is applied to the study of the conservation of RNA interference (RNAi) targets in human immunodeficiency virus 1 (HIV-1) subtype A. The developed pipeline is freely available to download at the website http://virmut.eimb.ru/. Brief comments and comparisons between VirMut and other pipelines are also presented. PMID- 29168756 TI - Hierarchical Mn2O3 Microspheres In-Situ Coated with Carbon for Supercapacitors with Highly Enhanced Performances. AB - Porous Mn2O3 microspheres have been synthesized and in-situ coated with amorphous carbon to form hierarchical C@Mn2O3 microspheres by first producing MnCO3 microspheres in solvothermal reactions, and then annealing at 500 degrees C. The self-assembly growth of MnCO3 microspheres can generate hollow structures inside each of the particles, which can act as micro-reservoirs to store biomass glycerol for generating amorphous carbon onto the surfaces of Mn2O3 nanorods consisting of microspheres. The C@Mn2O3 microspheres, prepared at 500 degrees C, exhibit highly enhanced pseudocapacitive performances when compared to the particles after annealed at 400 degrees C and 600 degrees C. Specifically, the C@Mn2O3 microspheres prepared at 500 degrees C show high specific capacitances of 383.87 F g-1 at current density of 0.5 A g-1, and excellent cycling stability of 90.47% of its initial value after cycling for 5000 times. The asymmetric supercapacitors assembled with C@Mn2O3 microspheres after annealed at 500 degrees C and activated carbon (AC) show an energy density of up to 77.8 Wh kg-1 at power density of 500.00 W kg-1, and a maximum power density of 20.14 kW kg-1 at energy density of 46.8 Wh kg-1. We can attribute the enhanced electrochemical performances of the materials to their three-dimensional (3D) hierarchical structure in-situ coated with carbon. PMID- 29168757 TI - Off-Nadir Hyperspectral Sensing for Estimation of Vertical Profile of Leaf Chlorophyll Content within Wheat Canopies. AB - Monitoring the vertical profile of leaf chlorophyll (Chl) content within winter wheat canopies is of significant importance for revealing the real nutritional status of the crop. Information on the vertical profile of Chl content is not accessible to nadir-viewing remote or proximal sensing. Off-nadir or multi-angle sensing would provide effective means to detect leaf Chl content in different vertical layers. However, adequate information on the selection of sensitive spectral bands and spectral index formulas for vertical leaf Chl content estimation is not yet available. In this study, all possible two-band and three band combinations over spectral bands in normalized difference vegetation index (NDVI)-, simple ratio (SR)- and chlorophyll index (CI)-like types of indices at different viewing angles were calculated and assessed for their capability of estimating leaf Chl for three vertical layers of wheat canopies. The vertical profiles of Chl showed top-down declining trends and the patterns of band combinations sensitive to leaf Chl content varied among different vertical layers. Results indicated that the combinations of green band (520 nm) with NIR bands were efficient in estimating upper leaf Chl content, whereas the red edge (695 nm) paired with NIR bands were dominant in quantifying leaf Chl in the lower layers. Correlations between published spectral indices and all NDVI-, SR- and CI like types of indices and vertical distribution of Chl content showed that reflectance measured from 50 degrees , 30 degrees and 20 degrees backscattering viewing angles were the most promising to obtain information on leaf Chl in the upper-, middle-, and bottom-layer, respectively. Three types of optimized spectral indices improved the accuracy for vertical leaf Chl content estimation. The optimized three-band CI-like index performed the best in the estimation of vertical distribution of leaf Chl content, with R2 of 0.84-0.69, and RMSE of 5.37 5.56 ug/cm2 from the top to the bottom layers, while the optimized SR-like index was recommended for the bottom Chl estimation due to its simple and universal form. We suggest that it is necessary to take into account the penetration characteristic of the light inside the canopy for different Chl absorption regions of the spectrum and the formula used to derive spectral index when estimating the vertical profile of leaf Chl content using off-nadir hyperspectral data. PMID- 29168755 TI - Regulation of G2/M Transition by Inhibition of WEE1 and PKMYT1 Kinases. AB - In the cell cycle, there are two checkpoint arrests that allow cells to repair damaged DNA in order to maintain genomic integrity. Many cancer cells have defective G1 checkpoint mechanisms, thus depending on the G2 checkpoint far more than normal cells. G2 checkpoint abrogation is therefore a promising concept to preferably damage cancerous cells over normal cells. The main factor influencing the decision to enter mitosis is a complex composed of Cdk1 and cyclin B. Cdk1/CycB is regulated by various feedback mechanisms, in particular inhibitory phosphorylations at Thr14 and Tyr15 of Cdk1. In fact, Cdk1/CycB activity is restricted by the balance between WEE family kinases and Cdc25 phosphatases. The WEE kinase family consists of three proteins: WEE1, PKMYT1, and the less important WEE1B. WEE1 exclusively mediates phosphorylation at Tyr15, whereas PKMYT1 is dual-specific for Tyr15 as well as Thr14. Inhibition by a small molecule inhibitor is therefore proposed to be a promising option since WEE kinases bind Cdk1, altering equilibria and thus affecting G2/M transition. PMID- 29168759 TI - Experimental Investigation on the Detection of Multiple Surface Cracks Using Vibrothermography with a Low-Power Piezoceramic Actuator. AB - Vibrothermography often employs a high-power actuator to generate heat on a specimen to reveal damage, however, the high-power actuator brings inconvenience to the application and possibly introduces additional damage to the inspected objects. This study uses a low-power piezoceramic transducer as the actuator of vibrothermography and explores its ability to detect multiple surface cracks in a metal part. Experiments were conducted on a thin aluminum beam with three cracks in different orientations. Detailed analyses of both thermograms and temperature data are presented to validate the proposed vibrothermography method. To further investigate the performance of the proposed vibrothermography method, we experimentally studied the effects of several critical factors, including the amplitude of excitation signal, specimen constraints, relative position between the transducer and cracks (the transducer is mounted on the same or the opposite side with the cracks). The results demonstrate that all cracks can be detected conveniently and simultaneously by using the proposed low-power vibrothermography. We also found that the magnitude of excitation signal and the specimen constraints have a great influence on detection results. Combined with effective data processing methods, such as Fourier transformation employed in this study, the proposed method provides a promising potential to detect multiple cracks on a metal surface in a safe and effective manner. PMID- 29168758 TI - The Content of Structural and Trace Elements in the Knee Joint Tissues. AB - Many elements are responsible for the balance in bone tissue, including those which constitute a substantial proportion of bone mass, i.e., calcium, phosphorus and magnesium, as well as minor elements such as strontium. In addition, toxic elements acquired via occupational and environmental exposure, e.g., Pb, are included in the basic bone tissue composition. The study objective was to determine the content of strontium, lead, calcium, phosphorus, sodium and magnesium in chosen components of the knee joint, i.e., tibia, femur and meniscus. The levels of Sr, Pb, Ca, P, Na and Mg were the highest in the tibia in both men and women, whereas the lowest in the meniscus. It should be noted that the levels of these elements were by far higher in the tibia and femur as compared to the meniscus. In the components of the knee joint, the level of strontium showed the greatest variation. Significant statistical differences were found between men and women only in the content of lead. PMID- 29168760 TI - Mesenchymal Stromal Cells for Antineoplastic Drug Loading and Delivery. AB - Mesenchymal stromal cells are a population of undifferentiated multipotent adult cells possessing extensive self-renewal properties and the potential to differentiate into a variety of mesenchymal lineage cells. They express broad anti-inflammatory and immunomodulatory activity on the immune system and after transplantation can interact with the surrounding microenvironment, promoting tissue healing and regeneration. For this reason, mesenchymal stromal cells have been widely used in regenerative medicine, both in preclinical and clinical settings. Another clinical application of mesenchymal stromal cells is the targeted delivery of chemotherapeutic agents to neoplastic cells, maximizing the cytotoxic activity against cancer cells and minimizing collateral damage to non neoplastic tissues. Mesenchymal stem cells are home to the stroma of several primary and metastatic neoplasms and hence can be used as vectors for targeted delivery of antineoplastic drugs to the tumour microenvironment, thereby reducing systemic toxicity and maximizing antitumour effects. Paclitaxel and gemcitabine are the chemotherapeutic drugs best loaded by mesenchymal stromal cells and delivered to neoplastic cells, whereas other agents, like pemetrexed, are not internalized by mesenchymal stromal cells and therefore are not suitable for advanced antineoplastic therapy. This review focuses on the state of the art of advanced antineoplastic cell therapy and its future perspectives, emphasizing in vitro and in vivo preclinical results and future clinical applications. PMID- 29168761 TI - Using a Particle Counter to Inform the Creation of Similar Exposure Groups and Sampling Protocols in a Structural Steel Fabrication Facility. AB - The objective of this project was to create similar exposure groups (SEGs) for occupational monitoring in a structural steel fabrication facility. Qualitative SEG formation involved worksite observation, interviews, and audits of materials and procedures. These were supplemented with preliminary task-based shop survey data collected using a condensation particle counter. A total of six SEGs were formed, with recommendations for occupational exposure sampling for five groups, as well as ambient sampling recommendations to address areas on the operational floor found to have higher particle concentrations. The combination of direct reading device data and qualitative SEG formation techniques is a valuable approach, as it contains both the monetary and temporal costs of worksite exposure monitoring. This approach also provides an empowering in-house analysis of potentially problematic areas, and results in the streamlining of occupational exposure assessment. PMID- 29168762 TI - Dual Roles of Fer Kinase Are Required for Proper Hematopoiesis and Vascular Endothelium Organization during Zebrafish Development. AB - Fer kinase, a protein involved in the regulation of cell-cell adhesion and proliferation, has been shown to be required during invertebrate development and has been implicated in leukemia, gastric cancer, and liver cancer. However, in vivo roles for Fer during vertebrate development have remained elusive. In this study, we bridge the gap between the invertebrate and vertebrate realms by showing that Fer kinase is required during zebrafish embryogenesis for normal hematopoiesis and vascular organization with distinct kinase dependent and independent functions. In situ hybridization, quantitative PCR and fluorescence activated cell sorting (FACS) analyses revealed an increase in both erythrocyte numbers and gene expression patterns as well as a decrease in the organization of vasculature endothelial cells. Furthermore, rescue experiments have shown that the regulation of hematopoietic proliferation is dependent on Fer kinase activity, while vascular organizing events only require Fer in a kinase independent manner. Our data suggest a model in which separate kinase dependent and independent functions of Fer act in conjunction with Notch activity in a divergent manner for hematopoietic determination and vascular tissue organization. PMID- 29168763 TI - Micro-Computed-Tomography-Guided Analysis of In Vitro Structural Modifications in Two Types of 45S5 Bioactive Glass Based Scaffolds. AB - Three-dimensional 45S5 bioactive glass (BG)-based scaffolds are being investigated for bone regeneration. Besides structural properties, controlled time-dependent alteration of scaffold morphology is crucial to achieve optimal scaffold characteristics for successful bone repair. There is no in vitro evidence concerning the dependence between structural characteristics and dissolution behavior of 45S5 BG-based scaffolds of different morphology. In this study, the dissolution behavior of scaffolds fabricated by the foam replica method using polyurethane foam (Group A) and maritime sponge Spongia Agaricina (Group B) as sacrificial templates was analyzed by micro-computed-tomography (uCT). The scaffolds were immersed in Dulbecco's Modified Eagle Medium for 56 days under static cell culture conditions and underwent uCT-analysis initially, and after 7, 14, and 56 days. Group A showed high porosity (91%) and trabecular structure formed by macro-pores (average diameter 692 um +/- 72 um). Group-B scaffolds were less porous (51%), revealing an optimal pore size distribution within the window of 110-500 um pore size diameter, combined with superior mechanical stability. Both groups showed similar structural alteration upon immersion. Surface area and scaffold volume increased whilst density decreased, reflecting initial dissolution followed by hydroxycarbonate-apatite-layer formation on the scaffold surfaces. In vitro- and/or in vivo-testing of cell seeded BG-scaffolds used in this study should be performed to evaluate the BG scaffolds' time-dependent osteogenic properties in relation to the measured in vitro structural changes. PMID- 29168764 TI - Cross-National Systematic Review of Neonatal Mortality and Postnatal Newborn Care: Special Focus on Pakistan. AB - The latest nationwide survey of Pakistan showed that considerable progress has been made toward reducing all child mortality indicators except neonatal mortality. The aim of this study is to compare Pakistan's under-five mortality, neonatal mortality, and postnatal newborn care rates with those of other countries. Neonatal mortality rates and postnatal newborn care rates from the Demographic and Health Surveys (DHSs) of nine low- and middle-income countries (LMIC) from Asia and Africa were analyzed. Pakistan's maternal, newborn, and child health (MNCH) policies and programs, which have been implemented in the country since 1990, were also analyzed. The results highlighted that postnatal newborn care in Pakistan was higher compared with the rest of countries, yet its neonatal mortality remained the worst. In Zimbabwe, both mortality rates have been increasing, whereas the neonatal mortality rates in Nepal and Afghanistan remained unchanged. An analysis of Pakistan's MNCH programs showed that there is no nationwide policy on neonatal health. There were only a few programs concerning the health of newborns, and those were limited in scale. Pakistan's example shows that increased coverage of neonatal care without ensuring quality is unlikely to improve neonatal survival rates. It is suggested that Pakistan needs a comprehensive policy on neonatal health similar to other countries, and its effective programs need to be scaled up, in order to obtain better neonatal health outcomes. PMID- 29168765 TI - Phenylazopyridine as Switch in Photochemical Reactions. A Detailed Computational Description of the Mechanism of Its Photoisomerization. AB - Azo compounds are organic photochromic systems that have the possibility of switching between cis and trans isomers under irradiation. The different photochemical properties of these isomers make azo compounds into good light triggered switches, and their significantly different geometries make them very interesting as components in molecular engines or mechanical switches. For instance, azo ligands are used in coordination complexes to trigger photoresponsive properties. The light-induced trans-to-cis isomerization of phenylazopyridine (PAPy) plays a fundamental role in the room-temperature switchable spin crossover of Ni-porphyrin derivatives. In this work, we present a computational study developed at the SA-CASSCF/CASPT2 level (State Averaged Complete Active Space Self Consistent Field/CAS second order Perturbation Theory) to elucidate the mechanism, up to now unknown, of the cis-trans photoisomerization of 3-PAPy. We have analyzed the possible reaction pathways along its lowest excited states, generated by excitation of one or two electrons from the lone pairs of the N atoms of the azo group (nazopi*2 and nazo2pi*2 states), from a pi delocalized molecular orbital (pipi* state), or from the lone pair of the N atom of the pyridine moiety (npypi* state). Our results show that the mechanism proceeds mainly along the rotation coordinate in both the nazopi* and pipi* excited states, although the nazo2pi*2 state can also be populated temporarily, while the npypi* does not intervene in the reaction. For rotationally constrained systems, accessible paths to reach the cis minimum along planar geometries have also been located, again on the nazopi* and pipi* potential energy surfaces, while the nazo2pi*2 and npypi* states are not involved in the reaction. The relative energies of the different paths differ from those found for azobenzene in a previous work, so our results predict some differences between the reactivities of both compounds. PMID- 29168766 TI - Tityus serrulatus Scorpion Venom: In Vitro Tests and Their Correlation with In Vivo Lethal Dose Assay. AB - Scorpion stings are the main cause of human envenomation in Brazil and, for the treatment of victims, the World Health Organization (WHO) recommends the use of antivenoms. The first step to achieve effective antivenom is to use a good quality venom pool and to evaluate it, with LD50 determination as the most accepted procedure. It is, however, time-consuming and requires advanced technical training. Further, there are significant ethical concerns regarding the number of animals required for testing. Hence, we investigated the correspondence between LD50 results, in vitro assays, and a strong correlation with proteolytic activity levels was observed, showing, remarkably, that proteases are potential toxicity markers for Tityus serrulatus venom. The comparison of reversed-phase chromatographic profiles also has a potential application in venoms' quality control, as there were fewer neurotoxins detected in the venom with high LD50 value. These results were confirmed by mass spectrometry analysis. Therefore, these methods could precede the LD50 assay to evaluate the venom excellence by discriminating-and discarding-poor-quality batches, and, consequently, with a positive impact on the number of animals used. Notably, proposed assays are fast and inexpensive, being technically and economically feasible in Tityus serrulatus venom quality control to produce effective antivenoms. PMID- 29168768 TI - Ionic Liquid-Mediated Homogeneous Esterification of Cinnamic Anhydride to Xylans. AB - A new functional biopolymer was synthesized through an ionic liquid-mediated homogeneous grafting of cinnamic anhydride to xylans. The ionic liquid used was 1 allyl-3-methylimidazolium chloride (AMIMCl) ionic liquid. Xylans with degrees of substitution (DS) between 0.11 and 0.57 were accessible in a completely homogeneous system by changing catalysts (NaOH, KOH and LiOH), time, reaction temperature, and cinnamic anhydride/xylan molar ratio. The chemical structure and the thermal stability of the derivatives were characterized by Fourier transform infrared spectroscopy (FT-IR), 13C-NMR spectroscopy, and thermogravimetry. The thermal stability of the derivatives was reduced compared with the original xylan. Possible applications of the cinnamic anhydride-acylated xylan derivatives include wet-end papermaking, organic-inorganic composite films, and hydrogels.

AB - Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third leading cause of cancer death in the world. Hepatitis B virus (HBV) and its X gene-encoded protein (HBx) play important roles in the progression of HCC. Although long non-coding RNAs (lncRNAs) cannot encode proteins, growing evidence indicates that they play essential roles in HCC progression, and contribute to cell proliferation, invasion and metastasis, autophagy, and apoptosis by targeting a large number of pivotal protein-coding genes, miRNAs, and signaling pathways. In this review, we briefly outline recent findings of differentially expressed lncRNAs in HBV-related HCC, with particular focus on several key lncRNAs, and discuss their regulation by HBV/HBx, their functions, and their underlying molecular mechanisms in the progression of HCC.

AB - Assistance during sit-to-stand (SiSt) transitions for frail elderly may be provided by powered orthotic devices. The control of the powered orthosis may be performed by the means of electromyography (EMG), which requires direct contact of measurement electrodes to the skin. The purpose of this study was to determine if a non-EMG-based method that uses inertial sensors placed at different positions on the orthosis, and a lightweight pattern recognition algorithm may accurately identify SiSt transitions without false positives. A novel method is proposed to eliminate false positives based on a two-stage design: stage one detects the sitting posture; stage two recognizes the initiation of a SiSt transition from a sitting position. The method was validated using data from 10 participants who performed 34 different activities and posture transitions. Features were obtained from the sensor signals and then combined into lagged epochs. A reduced number of features was selected using a minimum-redundancy maximum-relevance (mRMR) algorithm and forward feature selection. To obtain a recognition model with low computational complexity, we compared the use of an extreme learning machine (ELM) and multilayer perceptron (MLP) for both stages of the recognition algorithm. Both classifiers were able to accurately identify all posture transitions with no false positives. The average detection time was 0.19 +/- 0.33 s for ELM and 0.13 +/- 0.32 s for MLP. The MLP classifier exhibited less time complexity in the recognition phase compared to ELM. However, the ELM classifier presented lower computational demands in the training phase. Results demonstrated that the proposed algorithm could potentially be adopted to control a powered orthosis. PMID- 29168770 TI - Lanthanide-Doped Nanoparticles for Diagnostic Sensing. AB - Lanthanide-doped nanoparticles exhibit unique optical properties, such as a long luminescence lifetime (up to several milliseconds), sharp emission peaks, and upconversion luminescence over the range of wavelengths from near-infrared to visible. Exploiting these optical properties, lanthanide-doped nanoparticles have been widely utilized for cellular and small animal imaging with the absence of background autofluorescence. In addition, these nanoparticles have advantages of high signal-to-noise ratio for highly sensitive and selective diagnostic detection. In this review, we summarize and discuss recent progress in the development of highly sensitive diagnostic methods using lanthanide-doped nanoparticles. Combined with a smartphone, portable luminescence detecting platforms could be widely applied in point-of-care tests. PMID- 29168771 TI - Iron-Based Nanomaterials/Graphene Composites for Advanced Electrochemical Sensors. AB - Iron oxide nanostructures (IONs) in combination with graphene or its derivatives e.g., graphene oxide and reduced graphene oxide-hold great promise toward engineering of efficient nanocomposites for enhancing the performance of advanced devices in many applicative fields. Due to the peculiar electrical and electrocatalytic properties displayed by composite structures in nanoscale dimensions, increasing efforts have been directed in recent years toward tailoring the properties of IONs-graphene based nanocomposites for developing more efficient electrochemical sensors. In the present feature paper, we first reviewed the various routes for synthesizing IONs-graphene nanostructures, highlighting advantages, disadvantages and the key synthesis parameters for each method. Then, a comprehensive discussion is presented in the case of application of IONs-graphene based composites in electrochemical sensors for the determination of various kinds of (bio)chemical substances. PMID- 29168772 TI - A Survey of Recent Advances in Particle Filters and Remaining Challenges for Multitarget Tracking. AB - We review some advances of the particle filtering (PF) algorithm that have been achieved in the last decade in the context of target tracking, with regard to either a single target or multiple targets in the presence of false or missing data. The first part of our review is on remarkable achievements that have been made for the single-target PF from several aspects including importance proposal, computing efficiency, particle degeneracy/impoverishment and constrained/multi modal systems. The second part of our review is on analyzing the intractable challenges raised within the general multitarget (multi-sensor) tracking due to random target birth and termination, false alarm, misdetection, measurement-to track (M2T) uncertainty and track uncertainty. The mainstream multitarget PF approaches consist of two main classes, one based on M2T association approaches and the other not such as the finite set statistics-based PF. In either case, significant challenges remain due to unknown tracking scenarios and integrated tracking management.

AB - This paper describes and verifies a non-invasive blood glucose measurement method using a fiber Bragg grating (FBG) sensor system. The FBG sensor is installed on the radial artery, and the strain (pulse wave) that is propagated from the heartbeat is measured. The measured pulse wave signal was used as a collection of feature vectors for multivariate analysis aiming to determine the blood glucose level. The time axis of the pulse wave signal was normalized by two signal processing methods: the shortest-time-cut process and 1-s-normalization process. The measurement accuracy of the calculated blood glucose level was compared with the accuracy of these signal processing methods. It was impossible to calculate a blood glucose level exceeding 200 mg/dL in the calibration curve that was constructed by the shortest-time-cut process. In the 1-s-normalization process, the measurement accuracy of the blood glucose level was improved, and a blood glucose level exceeding 200 mg/dL could be calculated. By verifying the loading vector of each calibration curve to calculate the blood glucose level with a high measurement accuracy, we found the gradient of the peak of the pulse wave at the acceleration plethysmogram greatly affected. PMID- 29168775 TI - Wearable Stretch Sensors for Motion Measurement of the Wrist Joint Based on Dielectric Elastomers. AB - Motion capture of the human body potentially holds great significance for exoskeleton robots, human-computer interaction, sports analysis, rehabilitation research, and many other areas. Dielectric elastomer sensors (DESs) are excellent candidates for wearable human motion capture systems because of their intrinsic characteristics of softness, light weight, and compliance. In this paper, DESs were applied to measure all component motions of the wrist joints. Five sensors were mounted to different positions on the wrist, and each one is for one component motion. To find the best position to mount the sensors, the distribution of the muscles is analyzed. Even so, the component motions and the deformation of the sensors are coupled; therefore, a decoupling method was developed. By the decoupling algorithm, all component motions can be measured with a precision of 5 degrees , which meets the requirements of general motion capture systems. PMID- 29168776 TI - Enhancement of Osteoblastic-Like Cell Activity by Glow Discharge Plasma Surface Modified Hydroxyapatite/beta-Tricalcium Phosphate Bone Substitute. AB - Glow discharge plasma (GDP) treatments of biomaterials, such as hydroxyapatite/beta-tricalcium phosphate (HA/beta-TCP) composites, produce surfaces with fewer contaminants and may facilitate cell attachment and enhance bone regeneration. Thus, in this study we used argon glow discharge plasma (Ar GDP) treatments to modify HA/beta-TCP particle surfaces and investigated the physical and chemical properties of the resulting particles (HA/beta-TCP + Ar GDP). The HA/beta-TCP particles were treated with GDP for 15 min in argon gas at room temperature under the following conditions: power: 80 W; frequency: 13.56 MHz; pressure: 100 mTorr. Scanning electron microscope (SEM) observations showed similar rough surfaces of HA/beta-TCP + Ar-GDP HA/beta-TCP particles, and energy dispersive spectrometry analyses showed that HA/beta-TCP surfaces had more contaminants than HA/beta-TCP + Ar-GDP surfaces. Ca/P mole ratios in HA/beta-TCP and HA/beta-TCP + Ar-GDP were 1.34 and 1.58, respectively. Both biomaterials presented maximal intensities of X-ray diffraction patterns at 27 degrees with 600 a.u. At 25 degrees and 40 degrees , HA/beta-TCP + Ar-GDP and HA/beta-TCP particles had peaks of 200 a.u., which are similar to XRD intensities of human bone. In subsequent comparisons, MG-63 cell viability and differentiation into osteoblast-like cells were assessed on HA/beta-TCP and HA/beta-TCP + Ar-GDP surfaces, and Ar-GDP treatments led to improved cell growth and alkaline phosphatase activities. The present data indicate that GDP surface treatment modified HA/beta-TCP surfaces by eliminating contaminants, and the resulting graft material enhanced bone regeneration. PMID- 29168777 TI - Association of Emotional Labor and Occupational Stressors with Depressive Symptoms among Women Sales Workers at a Clothing Shopping Mall in the Republic of Korea: A Cross-Sectional Study. AB - In the distribution service industry, sales people often experience multiple occupational stressors such as excessive emotional labor, workplace mistreatment, and job insecurity. The present study aimed to explore the associations of these stressors with depressive symptoms among women sales workers at a clothing shopping mall in Korea. A cross sectional study was conducted on 583 women who consist of clothing sales workers and manual workers using a structured questionnaire to assess demographic factors, occupational stressors, and depressive symptoms. Multiple regression analyses were performed to explore the association of these stressors with depressive symptoms. Scores for job stress subscales such as job demand, job control, and job insecurity were higher among sales workers than among manual workers (p < 0.01). The multiple regression analysis revealed the association between occupation and depressive symptoms after controlling for age, educational level, cohabiting status, and occupational stressors (sbeta = 0.08, p = 0.04). A significant interaction effect between occupation and social support was also observed in this model (sbeta = -0.09, p = 0.02). The multiple regression analysis stratified by occupation showed that job demand, job insecurity, and workplace mistreatment were significantly associated with depressive symptoms in both occupations (p < 0.05), although the strength of statistical associations were slightly different. We found negative associations of social support (sbeta = -0.22, p < 0.01) and emotional effort (sbeta = -0.17, p < 0.01) with depressive symptoms in another multiple regression model for sales workers. Emotional dissonance (sbeta = 0.23, p < 0.01) showed positive association with depressive symptoms in this model. The result of this study indicated that reducing occupational stressors would be effective for women sales workers to prevent depressive symptoms. In particular, promoting social support could be the most effective way to promote women sales workers' mental health. PMID- 29168778 TI - Statistical Analysis of the Random Telegraph Noise in a 1.1 MUm Pixel, 8.3 MP CMOS Image Sensor Using On-Chip Time Constant Extraction Method. AB - A study of the random telegraph noise (RTN) of a 1.1 MUm pitch, 8.3 Mpixel CMOS image sensor (CIS) fabricated in a 45 nm backside-illumination (BSI) technology is presented in this paper. A noise decomposition scheme is used to pinpoint the noise source. The long tail of the random noise (RN) distribution is directly linked to the RTN from the pixel source follower (SF). The full 8.3 Mpixels are classified into four categories according to the observed RTN histogram peaks. A theoretical formula describing the RTN as a function of the time difference between the two phases of the correlated double sampling (CDS) is derived and validated by measured data. An on-chip time constant extraction method is developed and applied to the RTN analysis. The effects of readout circuit bandwidth on the settling ratios of the RTN histograms are investigated and successfully accounted for in a simulation using a RTN behavior model. PMID- 29168774 TI - Carotenoids from Marine Organisms: Biological Functions and Industrial Applications. AB - As is the case for terrestrial organisms, carotenoids represent the most common group of pigments in marine environments. They are generally biosynthesized by all autotrophic marine organisms, such as bacteria and archaea, algae and fungi. Some heterotrophic organisms also contain carotenoids probably accumulated from food or partly modified through metabolic reactions. These natural pigments are divided into two chemical classes: carotenes (such as lycopene and alpha- and beta-carotene) that are composed of hydrogen and carbon; xanthophylls (such as astaxanthin, fucoxanthin and lutein), which are constituted by hydrogen, carbon and oxygen. Carotenoids, as antioxidant compounds, assume a key role in the protection of cells. In fact, quenching of singlet oxygen, light capture and photosynthesis protection are the most relevant biological functions of carotenoids. The present review aims at describing (i) the biological functions of carotenoids and their benefits for human health, (ii) the most common carotenoids from marine organisms and (iii) carotenoids having large success in pharmaceutical, nutraceutical and cosmeceutical industries, highlighting the scientific progress in marine species cultivation for natural pigments production. PMID- 29168779 TI - Factors Effecting the Total Volatile Organic Compound (TVOC) Concentrations in Slovak Households. AB - Thirty five Slovak households were selected for an investigation of indoor environmental quality. Measuring of indoor air physical and chemical factors and a questionnaire survey was performed during May 2017. The range of permissible operative temperature was not met in 11% of objects. Relative humidity met the legislative requirements in all monitored homes. Concentrations of total volatile organic compounds (TVOCs) were significantly higher in the apartments than in the family houses. The average TVOC levels in the apartments and family houses were 519.7 ug/m3 and 330.2 ug/m3, respectively. Statistical analysis confirmed the effect of indoor air temperature, relative humidity and particulate matter (PM0.5 and PM1) on the levels of TVOCs. Higher TVOC levels were observed also in homes where it is not a common practice to open windows during cleaning activities. Other factors that had a statistically significant effect on concentrations of volatile organic compounds were heating type, attached garage, location of the apartment within residential building (the floor), as well as number of occupants. Higher TVOC concentrations were observed in indoor than outdoor environment, while further analysis showed the significant impact of indoor emission sources on the level of these compounds in buildings. The questionnaire study showed a discrepancy between objective measurement and subjective assessment in the household environment, and pointed to insufficient public awareness about volatile organic compounds (VOCs). PMID- 29168780 TI - Factors Associated with Dental Caries in Primary Dentition in a Non-Fluoridated Rural Community of New South Wales, Australia. AB - Dental caries persists as one of the most prevalent chronic diseases among children worldwide. This study aims to determine factors that influence dental caries in primary dentition among primary school children residing in the rural non-fluoridated community of Lithgow, New South Wales, Australia. A total of 495 children aged 5-10 years old from all the six primary schools in Lithgow were approached to participate in a cross-sectional survey prior to implementation of water fluoridation in 2014. Following parental consent, children were clinically examined for caries in their primary teeth, and parents were requested to complete a questionnaire on previous fluoride exposure, diet and relevant socio demographic characteristics that influence oral health. Multiple logistic regression analysis was employed to examine the independent risk factors of primary dentition caries. Overall, 51 percent of children had dental caries in one or more teeth. In the multiple logistic regression analysis, child's age (Adjusted Odd's Ratio (AOR) = 1.30, 95% CI: 1.14-1.49) and mother's extraction history (AOR = 2.05, 95% CI: 1.40-3.00) were significantly associated with caries experience in the child's primary teeth. In addition, each serve of chocolate consumption was associated with 52 percent higher odds (AOR = 1.52, 95% CI: 1.19 1.93) of primary dentition caries. PMID- 29168782 TI - The Preparation and Microstructure of Nanocrystal 3C-SiC/ZrO2 Bilayer Films. AB - The nanocrystal 3C-SiC/ZrO2 bilayer films that could be used as the protective coatings of zirconium alloy fuel cladding were prepared on a single-crystal Si substrate. The corresponding nanocrystal 3C-SiC film and nanocrystal ZrO2 film were also dividedly synthesized. The microstructure of nanocrystal films was analyzed by grazing incidence X-ray diffraction (GIXRD) and cross-sectional transmission electron microscopy (TEM). The 3C-SiC film with less than 30 nm crystal size was synthesized by Plasma Enhanced Chemical Vapor Deposition (PECVD) and annealing. The corresponding formation mechanism of some impurities in SiC film was analyzed and discussed. An amorphous Zr layer about 600 nm in width was first deposited by magnetron sputtering and then oxidized to form a nanocrystal ZrO2 layer during the annealing process. The interface characteristics of 3C SiC/ZrO2 bilayer films prepared by two different processes were obviously different. SiZr and SiO2 compounds were formed at the interface of 3C-SiC/ZrO2 bilayer films. A corrosion test of 3C-SiC/ZrO2 bilayer films was conducted to qualitatively analyze the surface corrosion resistance and the binding force of the interface.

AB - A Light Detection and Ranging (LiDAR) sensor mounted on an Unmanned Aerial Vehicle (UAV) can map the overflown environment in point clouds. Mapped canopy heights allow for the estimation of crop biomass in agriculture. The work presented in this paper contributes to sensory UAV setup design for mapping and textual analysis of agricultural fields. LiDAR data are combined with data from Global Navigation Satellite System (GNSS) and Inertial Measurement Unit (IMU) sensors to conduct environment mapping for point clouds. The proposed method facilitates LiDAR recordings in an experimental winter wheat field. Crop height estimates ranging from 0.35-0.58 m are correlated to the applied nitrogen treatments of 0-300 kg N ha . The LiDAR point clouds are recorded, mapped, and analysed using the functionalities of the Robot Operating System (ROS) and the Point Cloud Library (PCL). Crop volume estimation is based on a voxel grid with a spatial resolution of 0.04 * 0.04 * 0.001 m. Two different flight patterns are evaluated at an altitude of 6 m to determine the impacts of the mapped LiDAR measurements on crop volume estimations.

AB - Cyclodipeptides, called 2,5-diketopiperazines (2,5-DKPs), are obtained by the condensation of two amino acids. Fungi have been considered to be a rich source of novel and bioactive cyclodipeptides. This review highlights the occurrence, structures and biological activities of the fungal cyclodipeptides with the literature covered up to July 2017. A total of 635 fungal cyclodipeptides belonging to the groups of tryptophan-proline, tryptophan-tryptophan, tryptophan Xaa, proline-Xaa, non-tryptophan-non-proline, and thio-analogs have been discussed and reviewed. They were mainly isolated from the genera of Aspergillus and Penicillium. More and more cyclodipeptides have been isolated from marine derived and plant endophytic fungi. Some of them were screened to have cytotoxic, phytotoxic, antimicrobial, insecticidal, vasodilator, radical scavenging, antioxidant, brine shrimp lethal, antiviral, nematicidal, antituberculosis, and enzyme-inhibitory activities to show their potential applications in agriculture, medicinal, and food industry. PMID- 29168785 TI - FTUC: A Flooding Tree Uneven Clustering Protocol for a Wireless Sensor Network. AB - Clustering is an efficient approach in a wireless sensor network (WSN) to reduce the energy consumption of nodes and to extend the lifetime of the network. Unfortunately, this approach requires that all cluster heads (CHs) transmit their data to the base station (BS), which gives rise to the long distance communications problem, and in multi-hop routing, the CHs near the BS have to forward data from other nodes that lead those CHs to die prematurely, creating the hot zones problem. Unequal clustering has been proposed to solve these problems. Most of the current algorithms elect CH only by considering their competition radius, leading to unevenly distributed cluster heads. Furthermore, global distances values are needed when calculating the competition radius, which is a tedious task in large networks. To face these problems, we propose a flooding tree uneven clustering protocol (FTUC) suited for large networks. Based on the construction of a tree type sub-network to calculate the minimum and maximum distances values of the network, we then apply the unequal cluster theory. We also introduce referenced position circles to evenly elect cluster heads. Therefore, cluster heads are elected depending on the node's residual energy and their distance to a referenced circle. FTUC builds the best inter cluster communications route by evaluating a cluster head cost function to find the best next hop to the BS. The simulation results show that the FTUC algorithm decreases the energy consumption of the nodes and balances the global energy consumption effectively, thus extending the lifetime of the network. PMID- 29168784 TI - Optimization of the Use of His6-OPH-Based Enzymatic Biocatalysts for the Destruction of Chlorpyrifos in Soil. AB - Applying enzymatic biocatalysts based on hexahistidine-containing organophosphorus hydrolase (His6-OPH) is suggested for the decomposition of chlorpyrifos, which is actively used in agriculture in many countries. The application conditions were optimized and the following techniques was suggested to ensure the highest efficiency of the enzyme: first, the soil is alkalinized with hydrated calcitic lime Ca(OH)2, then the enzyme is introduced into the soil at a concentration of 1000 U/kg soil. Non-equilibrium low temperature plasma (NELTP)-modified zeolite is used for immobilization of the relatively inexpensive polyelectrolyte complexes containing the enzyme His6-OPH and a polyanionic polymer: poly-l-glutamic acid (PLE50) or poly-l-aspartic acid (PLD50). The soil's humidity is then increased up to 60-80%, the top layer (10-30 cm) of soil is thoroughly stirred, and then exposed for 48-72 h. The suggested approach ensures 100% destruction of the pesticide within 72 h in soils containing as much as 100 mg/kg of chlorpyrifos. It was concluded that using this type of His6-OPH-based enzyme chemical can be the best approach for soils with relatively low humus concentrations, such as sandy and loam-sandy chestnut soils, as well as types of soil with increased alkalinity (pH 8.0-8.4). Such soils are often encountered in desert, desert-steppe, foothills, and subtropical regions where chlorpyrifos is actively used.

AB - Introduction: Frailty syndrome and advanced age may decrease the acceptance of illness and quality of life, and worsen patients' existing health conditions, as well as leading to an increase in health care expenses. Purpose: The purpose of this study is to reduce frailty risk via the use of a FRED game which has been expressly designed and put together for the study. Materials and methods: A total of 40 frail volunteers with a score of <10 points in the short physical performance battery (SPPB) took part in a feasibility study in order to validate the FRED game. Following randomisation, the study group (20 subjects) took part in nine sessions of 20 min each over a three-week period. The control group (19 subjects) continued to lead their daily lives in the course of which they had no physical activity scheduled; Results: After three weeks and having taken part in nine physical activity sessions with the FRED game, 60% of subjects from the study group (12/20) obtained a score of >=10 points at the end of the study, i.e., less risk of evidencing frailty. This result proved to be statistically significant (p < 0.001). The degree of compliance with and adherence to the game was confirmed by 100% attendance of the sessions. Discussion: Our findings support the hypothesis that FRED, an ad hoc designed exergame, significantly reduced the presence and severity of frailty in a sample of sedentary elders, thus potentially modifying their risk profile. Conclusions: The FRED game is a tool that shows a 99% certain improvement in the degree of frailty in frail elderly subjects. The effectiveness of the design of ad hoc games in a certain pathology or population group is therefore evidenced. PMID- 29168788 TI - Microtubule Depolymerization by Kinase Inhibitors: Unexpected Findings of Dual Inhibitors. AB - Microtubule-targeting agents are widely used as clinical drugs in the treatment of cancer. However, some kinase inhibitors can also disrupt microtubule organization by directly binding to tubulin. These unexpected effects may result in a plethora of harmful events and/or a misinterpretation of the experimental results. Thus, further studies are needed to understand these dual inhibitors. In this review, I discuss the roles of dual inhibitors of kinase activity and microtubule function as well as describe the properties underlining their dual roles. Since both kinase and microtubule inhibitors cause cell toxicity and cell cycle arrest, it is difficult to determine which inhibitor is responsible for each phenotype. A discrimination of cell cycle arrest at G0/G1 or G2/M and/or image analyses of cellular phenotype may eventually lead to new insights on drug duality. Because of the indispensable roles of microtubules in mitosis and vesicle transport, I propose a simple and easy method to identify microtubule depolymerizing compounds.

AB - Evidence continues to accumulate that pesticides are the leading candidates of environmental toxins that may contribute to the pathogenesis of Parkinson's disease. The mechanisms, however, remain largely unclear. According to epidemiological studies, we selected nine representative pesticides (paraquat, rotenone, chlorpyrifos, pendimethalin, endosulfan, fenpyroximate, tebufenpyrad, trichlorphon and carbaryl) which are commonly used in China and detected the effects of the pesticides on mitochondria and ubiquitin-proteasome system (UPS) function. Our results reveal that all the nine studied pesticides induce morphological changes of mitochondria at low concentrations. Paraquat, rotenone, chlorpyrifos, pendimethalin, endosulfan, fenpyroximate and tebufenpyrad induced mitochondria fragmentation. Furthermore, some of them (paraquat, rotenone, chlorpyrifos, fenpyroximate and tebufenpyrad) caused a significant dose-dependent decrease of intracellular ATP. Interestingly, these pesticides which induce mitochondria dysfunction also inhibit 26S and 20S proteasome activity. However, two out of the nine pesticides, namely trichlorphon and carbaryl, were found not to cause mitochondrial fragmentation or functional damage, nor inhibit the activity of the proteasome, which provides significant guidance for selection of pesticides in China. Moreover, our results demonstrate a potential link between inhibition of mitochondria and the UPS, and pesticide-induced Parkinsonism. PMID- 29168789 TI - Lead Emissions and Population Vulnerability in the Detroit (Michigan, USA) Metropolitan Area, 2006-2013: A Spatial and Temporal Analysis. AB - Objective: The purpose of this research is to geographically model airborne lead emission concentrations and total lead deposition in the Detroit Metropolitan Area (DMA) from 2006 to 2013. Further, this study characterizes the racial and socioeconomic composition of recipient neighborhoods and estimates the potential for IQ (Intelligence Quotient) loss of children residing there. Methods: Lead emissions were modeled from emitting facilities in the DMA using AERMOD (American Meteorological Society/Environmental Protection Agency Regulatory Model). Multilevel modeling was used to estimate local racial residential segregation, controlling for poverty. Global Moran's I bivariate spatial autocorrelation statistics were used to assess modeled emissions with increasing segregation. Results: Lead emitting facilities were primarily located in, and moving to, highly black segregated neighborhoods regardless of poverty levels-a phenomenon known as environmental injustice. The findings from this research showed three years of elevated airborne emission concentrations in these neighborhoods to equate to a predicted 1.0 to 3.0 reduction in IQ points for children living there. Across the DMA there are many areas where annual lead deposition was substantially higher than recommended for aquatic (rivers, lakes, etc.) and terrestrial (forests, dunes, etc.) ecosystems. These lead levels result in decreased reproductive and growth rates in plants and animals, and neurological deficits in vertebrates. Conclusions: This lead-hazard and neighborhood context assessment will inform future childhood lead exposure studies and potential health consequences in the DMA.

C. burnetii is an intracellular bacterium that can survive inside microbicidal cells like monocytes and macrophages by hijacking several functions of the immune system. Among several virulence factors, the lipopolysaccharide (LPS) of C. burnetii is one of the major factors involved in this immune hijacking because of its atypical composition and structure. Thus, the aim of this mini-review is to summarize the repressive effects of C. burnetii LPS on the antibacterial immunity of cells. PMID- 29168791 TI - Administration of Protocatechuic Acid Reduces Traumatic Brain Injury-Induced Neuronal Death. AB - Protocatechuic acid (PCA) was first purified from green tea and has shown numerous biological activities, including anti-apoptotic, anti-inflammatory, and anti-atherosclerotic effects. The effect of PCA on traumatic brain injury (TBI) induced neuronal death has not previously been evaluated. TBI is defined as damage to the brain resulting from external mechanical force, such as rapid acceleration or deceleration, impact, blast waves, or penetration by a projectile. TBI causes neuronal death in the hippocampus and cerebral cortex. The present study aimed to evaluate the therapeutic potential of PCA on TBI-induced neuronal death. Here, TBI was induced by a controlled cortical impact model using rats. PCA (30 mg/kg) was injected into the intraperitoneal (ip) space immediately after TBI. Neuronal death was evaluated with Fluoro Jade-B (FJB) staining at 24 h after TBI. Oxidative injury was detected by 4-hydroxy-2-nonenal (4HNE), glutathione (GSH) concentration was analyzed by glutathione adduct with N ethylmaleimide (GS-NEM) staining at 24 h after TBI, and microglial activation in the hippocampus was detected by CD11b immunohistochemistry at one week after TBI. We found that the proportion of degenerating neurons, oxidative injury, GSH depletion, and microglia activation in the hippocampus and cortex were all reduced by PCA treatment following TBI. Therefore, our study suggests that PCA may have therapeutic potential in preventing TBI-induced neuronal death. PMID- 29168792 TI - Zinc Signal in Brain Diseases. AB - The divalent cation zinc is an integral requirement for optimal cellular processes, whereby it contributes to the function of over 300 enzymes, regulates intracellular signal transduction, and contributes to efficient synaptic transmission in the central nervous system. Given the critical role of zinc in a breadth of cellular processes, its cellular distribution and local tissue level concentrations remain tightly regulated via a series of proteins, primarily including zinc transporter and zinc import proteins. A loss of function of these regulatory pathways, or dietary alterations that result in a change in zinc homeostasis in the brain, can all lead to a myriad of pathological conditions with both acute and chronic effects on function. This review aims to highlight the role of zinc signaling in the central nervous system, where it may precipitate or potentiate diverse issues such as age-related cognitive decline, depression, Alzheimer's disease or negative outcomes following brain injury.

AB - Tertiary amines 3-(dialkylamino)-2-hydroxypropyl 4 [(alkoxycarbonyl)amino]benzoates and their quaternary ammonium salts were synthesized. The final step of synthesis of quaternary ammonium salts was carried out by microwave-assisted synthesis. Software-calculated data provided the background needed to compare fifteen new resulting compounds by their physicochemical properties. The acid dissociation constant (pKa) and lipophilicity index (log P) of tertiary amines were determined; while quaternary ammonium salts were characterized by software-calculated lipophilicity index and surface tension. Biological evaluation aimed at testing acetylcholinesterase and butyrylcholinesterase-inhibiting activity of synthesized compounds. A possible mechanism of action of these compounds was determined by molecular modelling study using combined techniques of docking; molecular dynamics simulations and quantum mechanics calculations. PMID- 29168794 TI - In Vitro Evaluation of PCL and P(3HB) as Coating Materials for Selective Laser Melted Porous Titanium Implants. AB - Titanium is widely used as a bone implant material due to its biocompatibility and high resilience. Since its Young's modulus differs from bone tissue, the resulting "stress shielding" could lead to scaffold loosening. However, by using a scaffold-shaped geometry, the Young's modulus can be adjusted. Also, a porous geometry enables vascularisation and bone ingrowth inside the implant itself. Additionally, growth factors can improve these effects. In order to create a deposit and release system for these factors, the titanium scaffolds could be coated with degradable polymers. Therefore, in the present study, synthetic poly epsilon-caprolactone (PCL) and the biopolymer poly(3-hydroxybutyrate) (P(3HB)) were tested for coating efficiency, cell adhesion, and biocompatibility to find a suitable coating material. The underlying scaffold was created from titanium by Selective Laser Melting (SLM) and coated with PCL or P(3HB) via dip coating. To test the biocompatibility, Live Cell Imaging (LCI) as well as vitality and proliferation assays were performed. In addition, cell adhesion forces were detected via Single Cell Force Spectroscopy, while the coating efficiency was observed using environmental scanning electron microscopy (ESEM) and energy dispersive X-ray (EDX) analyses. Regarding the coating efficiency, PCL showed higher values in comparison to P(3HB). Vitality assays revealed decent vitality values for both polymers, while values for PCL were significantly lower than those for blank titanium. No significant differences could be observed between PCL and P(3HB) in proliferation and cell adhesion studies. Although LCI observations revealed decreasing values in cell number and populated area over time on both polymer-coated scaffolds, these outcomes could be explained by the possibility of coating diluent residues accumulating in the culture medium. Overall, both polymers fulfill the requirements regarding biocompatibility. Nonetheless, since only PCL coating ensured the maintenance of the porous implant structure, it is preferable to be used as a coating material for creating a deposit and release system for growth factors. PMID- 29168795 TI - Antipsychotic Polypharmacy among Children and Young Adults in Office-Based or Hospital Outpatient Department Settings. AB - The purpose of the study was three-fold: (1) to estimate the national trends in antipsychotic (AP) polypharmacy among 6- to 24-year-old patients in the U.S.; (2) to identify frequently used AP agents and mental disorder diagnoses related to AP polypharmacy; and (3) to assess the strength of association between AP polypharmacy and patient/provider characteristics. We used publicly available ambulatory health care datasets to evaluate AP polypharmacy in office-based or hospital outpatient department settings to conduct a cross-sectional study. First, national visit rates between 2007 and 2011 were estimated using sampling weights. Second, common diagnoses and drugs used in AP polypharmacy were identified. Third, a multivariate logistic regression model was developed to assess the strength of association between AP polypharmacy and patient and provider characteristics. Between 2007 and 2011, approximately 2% of office-based or hospital outpatient department visits made by 6- to 24-year-old patients included one or more AP prescriptions. Of these visits, 5% were classified as AP polypharmacy. The most common combination of AP polypharmacy was to use two or more second-generation APs. Also, bipolar disorder and schizophrenia were the two most frequent primary mental disorder diagnoses among AP polypharmacy visits. The factors associated with AP polypharmacy were: older age (young adults), black, having one or more non-AP prescriptions, and having schizophrenia or ADHD.

AB - Layered Eu-doped SnO2 ordered nanoarrays constructed by nanorods with 10 nm diameters and several hundred nanometers length were synthesized by a substrate free hydrothermal route using alcohol and water mixed solvent of sodium stannate and sodium hydroxide at 200 degrees C. The Eu dopant acted as a crystal growth inhibitor to prevent the SnO2 nanorods growth up, resulting in tenuous SnO2 nanorods ordered arrays. The X-ray diffraction (XRD) revealed the tetragonal rutile-type structure with a systematic average size reduction and unit cell volume tumescence, while enhancing the residual strain as the Eu-doped content increases. The surface defects that were caused by the incorporation of Eu ions within the surface oxide matrix were observed by high-resolution transmission electron microscope (HRTEM). The results of the response properties of sensors based on the different levels of Eu-doped SnO2 layered nanoarrays demonstrated that the 0.5 at % Eu-doped SnO2 layered nanorods arrays exhibited an excellent sensing response to methanal at 278 degrees C. The reasons of the enhanced sensing performance were discussed from the complicated defect surface structure, the large specific surface area, and the excellent catalytic properties of Eu dopant. PMID- 29168798 TI - Removal of Ciprofloxacin from Aqueous Solutions Using Pillared Clays. AB - Emerging contaminants in the environment have caused enormous concern in the last few decades, and among them, antibiotics have received special attention. On the other hand, adsorption has shown to be a useful, low-cost, and eco-friendly method for the removal of this type of contaminants from water. This work is focused on the study of ciprofloxacin (CPX) removal from water by adsorption on pillared clays (PILC) under basic pH conditions, where CPX is in its anionic form (CPX-). Four different materials were synthetized, characterized, and studied as adsorbents of CPX (Al-, Fe-, Si-, and Zr-PILC). The highest CPX adsorption capacities of 100.6 and 122.1 mg g-1 were obtained for the Si- and Fe-PILC (respectively), and can be related to the porous structure of the PILCs. The suggested adsorption mechanism involves inner-sphere complexes formation as well as van der Waals interactions between CPX- and the available adsorption sites on the PILC surfaces. PMID- 29168799 TI - Modulation of Cytochrome P450, P-glycoprotein and Pregnane X Receptor by Selected Antimalarial Herbs-Implication for Herb-Drug Interaction. AB - Seven medicinal plants popularly used for treating malaria in West Africa were selected to assess herb-drug interaction potential through a series of in vitro methods. Fluorescent cytochrome P450 (CYP) assays were conducted using the recombinant CYP enzymes for CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2C19, CYP2D6 and CYP3A4 to assess the effect of the methanolic extracts on the metabolic activity of CYPs. Secondly, the inhibitory effect of the extracts was evaluated on P glycoproteins (P-gp) using calcein-AM, a fluorescent substrate, in MDCK-II and hMDR1-MDCK-II cells. The inhibition of P-gp activity was determined as a reflection of increase in calcein-AM uptake. Additionally, the enzyme induction potential of the extracts was assessed through the modulation of PXR activity in HepG2 cells transiently transfected with pSG5-PXR and PCR5 plasmid DNA. Significant inhibition of CYP activity (IC50 < 10 ug/mL) was observed with the following herbs: A. muricata [CYP2C9, 3A4 and CYP2D6]; M. indica [CYP2C9]; M. charantia [CYP2C9 and CYP2C19]; P. amarus [CYP2C19, CYP2C9 and CYP3A4]; T. diversifolia [CYP2C19 and CYP3A4]. Extracts of four herbs (P. amarus, M. charantia, T. diversifolia and A. muricata) exhibited significant inhibition of P gp with IC50 values (ug/mL) of 17 +/- 1, 16 +/- 0.4, 26 +/- 1, and 24 +/- 1, respectively. In addition, four herbs (A. mexicana, M. charantia, P. amarus and T. diversifolia) showed a >two-fold increase in induction in PXR activity. These findings suggest that these herbs may be capable of eliciting herb-drug interactions if consumed in high quantities with concomitant use of conventional therapies. PMID- 29168797 TI - Role of Vitamin E in the Treatment of Alzheimer's Disease: Evidence from Animal Models. AB - Alzheimer's disease (AD) is a neurodegenerative disorder representing the major cause of dementia. It is characterized by memory loss, and cognitive and behavioral decline. In particular, the hallmarks of the pathology are amyloid beta (Abeta) plaques and neurofibrillary tangles (NFTs), formed by aggregated hyperphosphorylated tau protein. Oxidative stress plays a main role in AD, and it is involved in initiation and progression of AD. It is well known that Abeta induced oxidative stress, promoting reactive oxygen species (ROS) production and consequently lipid peroxidation, protein oxidation, tau hyperphosphorylation, results in toxic effects on synapses and neurons. In turn, oxidative stress can increase Abeta production. For these reasons, the administration of an antioxidant therapy in AD patients was suggested. The term vitamin E includes different fat-soluble compounds, divided into tocopherols and tocotrienols, that possess antioxidant action. alpha-Tocopherol is the most studied, but some studies suggested that tocotrienols may have different health promoting capacities. In this review, we focused our attention on the effects of vitamin E supplementation in AD animal models and AD patients or older population. Experimental models showed that vitamin E supplementation, by decreasing oxidative stress, may be a good strategy to improve cognitive and memory deficits. Furthermore, the combination of vitamin E with other antioxidant or anti-inflammatory compounds may increase its efficacy. However, even if some trials have evidenced some benefits, the effects of vitamin E in AD patients are still under debate. PMID- 29168800 TI - The Effect of a Two-Stage Heat-Treatment on the Microstructural and Mechanical Properties of a Maraging Steel. AB - Maraging steels gain many of their beneficial properties from heat treatments which induce the precipitation of intermetallic compounds. We consider here a two stage heat-treatment, first involving austenitisation, followed by quenching to produce martensite and then an ageing treatment at a lower temperature to precipitation harden the martensite of a maraging steel. It is shown that with a suitable choice of the initial austenitisation temperature, the steel can be heat treated to produce enhanced toughness, strength and creep resistance. A combination of small angle neutron scattering, scanning electron microscopy, electron back-scattered diffraction, and atom probe tomography were used to relate the microstructural changes to mechanical properties. It is shown that such a combination of characterisation methods is necessary to quantify this complex alloy, and relate these microstructural changes to mechanical properties. It is concluded that a higher austenitisation temperature leads to a greater volume fraction of smaller Laves phase precipitates formed during ageing, which increase the strength and creep resistance but reduces toughness. PMID- 29168801 TI - The histone code reader Spin1 controls skeletal muscle development. AB - While several studies correlated increased expression of the histone code reader Spin1 with tumor formation or growth, little is known about physiological functions of the protein. We generated Spin1M5 mice with ablation of Spin1 in myoblast precursors using the Myf5-Cre deleter strain. Most Spin1M5 mice die shortly after birth displaying severe sarcomere disorganization and necrosis. Surviving Spin1M5 mice are growth-retarded and exhibit the most prominent defects in soleus, tibialis anterior, and diaphragm muscle. Transcriptome analyses of limb muscle at embryonic day (E) 15.5, E16.5, and at three weeks of age provided evidence for aberrant fetal myogenesis and identified deregulated skeletal muscle (SkM) functional networks. Determination of genome-wide chromatin occupancy in primary myoblast revealed direct Spin1 target genes and suggested that deregulated basic helix-loop-helix transcription factor networks account for developmental defects in Spin1M5 fetuses. Furthermore, correlating histological and transcriptome analyses, we show that aberrant expression of titin-associated proteins, abnormal glycogen metabolism, and neuromuscular junction defects contribute to SkM pathology in Spin1M5 mice. Together, we describe the first example of a histone code reader controlling SkM development in mice, which hints at Spin1 as a potential player in human SkM disease. PMID- 29168802 TI - Ligand-accelerated non-directed C-H functionalization of arenes. AB - The directed activation of carbon-hydrogen bonds (C-H) is important in the development of synthetically useful reactions, owing to the proximity-induced reactivity and selectivity that is enabled by coordinating functional groups. Palladium-catalysed non-directed C-H activation could potentially enable further useful reactions, because it can reach more distant sites and be applied to substrates that do not contain appropriate directing groups; however, its development has faced substantial challenges associated with the lack of sufficiently active palladium catalysts. Currently used palladium catalysts are reactive only with electron-rich arenes, unless an excess of arene is used, which limits synthetic applications. Here we report a 2-pyridone ligand that binds to palladium and accelerates non-directed C-H functionalization with arene as the limiting reagent. This protocol is compatible with a broad range of aromatic substrates and we demonstrate direct functionalization of advanced synthetic intermediates, drug molecules and natural products that cannot be used in excessive quantities. We also developed C-H olefination and carboxylation protocols, demonstrating the applicability of our methodology to other transformations. The site selectivity in these transformations is governed by a combination of steric and electronic effects, with the pyridone ligand enhancing the influence of sterics on the selectivity, thus providing complementary selectivity to directed C-H functionalization. PMID- 29168803 TI - Photonuclear reactions triggered by lightning discharge. AB - Lightning and thunderclouds are natural particle accelerators. Avalanches of relativistic runaway electrons, which develop in electric fields within thunderclouds, emit bremsstrahlung gamma-rays. These gamma-rays have been detected by ground-based observatories, by airborne detectors and as terrestrial gamma-ray flashes from space. The energy of the gamma-rays is sufficiently high that they can trigger atmospheric photonuclear reactions that produce neutrons and eventually positrons via beta+ decay of the unstable radioactive isotopes, most notably 13N, which is generated via 14N + gamma -> 13N + n, where gamma denotes a photon and n a neutron. However, this reaction has hitherto not been observed conclusively, despite increasing observational evidence of neutrons and positrons that are presumably derived from such reactions. Here we report ground based observations of neutron and positron signals after lightning. During a thunderstorm on 6 February 2017 in Japan, a gamma-ray flash with a duration of less than one millisecond was detected at our monitoring sites 0.5-1.7 kilometres away from the lightning. The subsequent gamma-ray afterglow subsided quickly, with an exponential decay constant of 40-60 milliseconds, and was followed by prolonged line emission at about 0.511 megaelectronvolts, which lasted for a minute. The observed decay timescale and spectral cutoff at about 10 megaelectronvolts of the gamma-ray afterglow are well explained by de-excitation gamma-rays from nuclei excited by neutron capture. The centre energy of the prolonged line emission corresponds to electron-positron annihilation, providing conclusive evidence of positrons being produced after the lightning. PMID- 29168804 TI - Hydrogen-bearing iron peroxide and the origin of ultralow-velocity zones. AB - Ultralow-velocity zones (ULVZs) at Earth's core-mantle boundary region have important implications for the chemical composition and thermal structure of our planet, but their origin has long been debated. Hydrogen-bearing iron peroxide (FeO2Hx) in the pyrite-type crystal structure was recently found to be stable under the conditions of the lowermost mantle. Using high-pressure experiments and theoretical calculations, we find that iron peroxide with a varying amount of hydrogen has a high density and high Poisson ratio as well as extremely low sound velocities consistent with ULVZs. Here we also report a reaction between iron and water at 86 gigapascals and 2,200 kelvin that produces FeO2Hx. This would provide a mechanism for generating the observed volume occupied by ULVZs through the reaction of about one-tenth the mass of Earth's ocean water in subducted hydrous minerals with the effectively unlimited reservoir of iron in Earth's core. Unlike other candidates for the composition of ULVZs, FeO2Hx synthesized from the superoxidation of iron by water would not require an extra transportation mechanism to migrate to the core-mantle boundary. These dense FeO2Hx-rich domains would be expected to form directly in the core-mantle boundary region and their properties would provide an explanation for the many enigmatic seismic features that are observed in ULVZs.

AB - Interfacing fundamentally different quantum systems is key to building future hybrid quantum networks. Such heterogeneous networks offer capabilities superior to those of their homogeneous counterparts, as they merge the individual advantages of disparate quantum nodes in a single network architecture. However, few investigations of optical hybrid interconnections have been carried out, owing to fundamental and technological challenges such as wavelength and bandwidth matching of the interfacing photons. Here we report optical quantum interconnection of two disparate matter quantum systems with photon storage capabilities. We show that a quantum state can be transferred faithfully between a cold atomic ensemble and a rare-earth-doped crystal by means of a single photon at 1,552 nanometre telecommunication wavelength, using cascaded quantum frequency conversion. We demonstrate that quantum correlations between a photon and a single collective spin excitation in the cold atomic ensemble can be transferred to the solid-state system. We also show that single-photon time-bin qubits generated in the cold atomic ensemble can be converted, stored and retrieved from the crystal with a conditional qubit fidelity of more than 85 per cent. Our results open up the prospect of optically connecting quantum nodes with different capabilities and represent an important step towards the realization of large-scale hybrid quantum networks.

AB - Plasmonic photocatalyst has attracted significant attention due to its valuable theoretical study and promising practical applications in solar cells, functional composites, and sensors. Herein, an interesting RGO-C3N4-supported AuAg core-Au shell (AuAg@Au) nanocomposite has been reported. Due to the surface plasmon resonance (SPR) of AuAg@Au and the accelarated electron transfer and separation of charge carriers induced by the fascinating RGO-C3N4 substrate, the newly generated AuAg@Au/RGO-C3N4 nanomaterials show a strong photo-electrochemical response under visible-light irradiation. The AuAg@Au/RGO-C3N4 photocatalyst demonstrated an excellent photo-electrochemical performance with a broad concentration linear range of 0.064-780.904 MUM and a low detection limit of 0.022 MUM, high stability, and good selectivity when applied in the determination of dopamine (DA) under visible-light irradiation. PMID- 29168845 TI - An ionic liquid-magnetic graphene composite for magnet dispersive solid-phase extraction of triazine herbicides in surface water followed by high performance liquid chromatography. AB - A new ionic liquid-magnetic graphene (IL-MG) composite was used as the adsorbent in magnetic dispersive solid-phase extraction to rapidly extract and isolate triazine herbicides from surface water. IL-MG was synthesized by a simple and time-saving one-pot strategy where the synthesis of magnetic Fe3O4, the modification with an IL, and the reduction of graphene oxide to graphene were conducted at the same time. An IL was applied to enrich the interaction mechanism between IL-MG and analytes (pi-pi, hydrophobic interaction, and electrostatic interaction). Moreover, the IL and Fe3O4 nanoparticles acted as spacers, inserting between the layers of graphene to prevent the aggregation of graphene, which improved the adsorption ability because of the large specific surface area of IL-MG. The resultant IL-MG had hierarchical flake structures and showed a high adsorption capacity (8266.0-12 324.1 MUg g-1) toward triazine herbicides. Under suitable conditions, the linearity for triazine herbicides was achieved in the range of 0.55-500 ng mL-1 with a detection limit of 0.09-0.15 ng mL-1 and a quantitation limit of 0.31-0.51 ng mL-1, and the enrichment factor was 83-fold, which indicated that the proposed method could be successfully applied for the determination of triazine herbicides in surface water. PMID- 29168846 TI - Rapid, portable detection of endocrine disrupting chemicals through ligand nuclear hormone receptor interactions. AB - Endocrine disrupting chemicals (EDC) are structurally diverse compounds that can interact with nuclear hormone receptors, posing significant risk to human and ecological health. Unfortunately, many conventional biosensors have been too structure-specific, labor-intensive or laboratory-oriented to detect broad ranges of EDC effectively. Recently, several technological advances are providing more rapid, portable, and affordable detection of endocrine-disrupting activity through ligand-nuclear hormone receptor interactions. Here, we overview these recent advances applied to EDC biosensors - including cell lyophilization, cell immobilization, cell-free systems, smartphone-based signal detection, and improved competitive binding assays. PMID- 29168847 TI - An aptamer and functionalized nanoparticle-based strip biosensor for on-site detection of kanamycin in food samples. AB - A lateral flow strip biosensor for fast, sensitive, low-cost and on-site detection of kanamycin was developed by using kanamycin-specific aptamer-modified gold nanoparticles (AuNPs-apt) as a probe and oligonucleotide DNA1-modified silver nanoparticles (AgNPs-DNA1) as a signal amplification element. Through the complementary sequences of DNA1 and the aptamer, the AgNP-DNA1-apt-AuNPs complex can be formed and further captured on the test zone of the strip, where a capture probe DNA2 complementary to the 3'-terminal of DNA1 was immobilized. In the presence of kanamycin, it can competitively bind to the aptamer, and then inhibit the formation of the complex and the accumulation of AuNPs on the test zone. AuNPs-apt can finally be captured on the control zone via the specific binding between biotin and streptavidin. The assay avoids multiple incubation and washing steps and can be completed within 10 min. By observing the color change of the test zone, a qualitative detection for kanamycin can be achieved by the naked eye, with the visual limit of 35 nM. Meanwhile, a linear detection range of 1-30 nM with a low detection limit of 0.0778 nM for quantitative analysis can be achieved by using a scanning reader. The lateral flow strip biosensor exhibited high specificity and stability. Moreover, it was applied to detect kanamycin in various food samples, indicating its great potential in field testing. PMID- 29168848 TI - An etching based fluorescent probe for sensitive detection of hydrogen sulfide in cells. AB - Hydrogen sulfide (H2S) is one of the most crucial gas signaling agents that mediate many physiological and pathological processes. However, rapid high efficiency detection and imaging of H2S in living cells is very challenging. Herein we reported a simple fluorescent nanoprobe using FAM-DNA/AgNP nanocomposites for fast and sensitive H2S detection based on surface silver displacement. In contrast to the conventional principles for fluorescence turn-on analyte detection, the present work demonstrated a sensitive and selective AgNP based optosensor for the assay of H2S. Compared with the majority of the reported H2S probes, complex synthesis procedures and costly equipment are not involved in this assay. PMID- 29168849 TI - Highly effective target converting strategy for ultrasensitive electrochemical assay of Hg2. AB - An electrochemical sensing system based on a highly effective mercuric ion (Hg2+) converting strategy and rolling circle amplification (RCA) is developed for the ultrasensitive detection of Hg2+. The Hg2+ converting strategy is implemented based on Hg2+ specific recognition thymine-Hg2+-thymine (T-Hg2+-T)-induced DNA strand displacement. First, polystyrene magnetic microspheres coated by AuNPs (Au@PSC) as a magnetic separator were labeled with ssDNA D1 (thymine-rich) and S1/D2 DNA duplex (guanine-rich S1). In the presence of Hg2+ and long ssDNA D3 (thymine-rich at the 5' end), the formation of a stable T-Hg2+-T structure between D2 and D3 pushes S1 out from the S1/D2 DNA duplex, realizing the conversion of input target Hg2+ into output S1. Thus, the total amount of output S1 is proportional to the amount of input Hg2+. Thereafter, the output S1 serves as the primer to perform RCA to obtain long guanine-rich ssDNA, which could be further hybridized with the capture DNA on the electrode surface. Subsequently, methylene blue (MB) as an electron mediator interacts with the ssDNA polymers via electrostatic binding to produce a detection signal. The electrochemical biosensor exhibits a wide linear range of 1 pM to 1 MUM with a low detection limit of 0.684 pM. Importantly, this sensor can be successfully applied in water samples with good accuracy and excellent recovery, which indicates its potential for Hg2+ detection in the environment.

PMID- 29168851 TI - Non-staining visualization of embryogenesis and energy metabolism in medaka fish eggs using near-infrared spectroscopy and imaging. AB - The energy metabolism and embryogenesis of fertilized Japanese medaka eggs were investigated in vivo at the molecular level using near-infrared (NIR) spectroscopy and imaging. Changes in chemical components, such as proteins and lipids, in yolk sphere and embryonic body were studied over the course of embryonic development. Metabolic changes that represent variations in the concentrations and molecular compositions of proteins and lipids in the yolk part, particularly on the 1st day after fertilization and the day just before hatching, were successfully identified in the 4900-4000 cm-1 wavenumber region. The yolk components were shown to have specific functions at the very early and final stages of the embryonic development. Proteins with alpha-helix- or beta sheet-rich structures clearly showed the different variation patterns within the developing egg. Furthermore, the distribution of lipids could be selectively visualized using data from the higher wavenumber region. Detailed embryonic structures were clearly depicted in the NIR images using the data from the 6400 5500 cm-1 region in which the embryo parts had some characteristic peaks due to unsaturated fatty acids. It was made clear that yolk and embryo parts had different components especially lipid components. The present study provides new insights into material variations in the fertilized egg during its growth. NIR imaging proved to be valuable in investigating the embryogenesis in vivo at the molecular level in terms of changes in biomolecular concentrations and compositions, metabolic differentiation, and detailed information about embryonic structures without the need for staining.

AB - A transition metal free, straightforward synthetic method for the preparation of substituted imidazoles is reported herein.

PMID- 29168853 TI - Electrospun flexible poly(bisphenol A carbonate) nanofibers decorated with Ag nanoparticles as effective 3D SERS substrates for trace TNT detection. AB - A flexible 3D hybrid PC/Ag surface-enhanced Raman scattering (SERS) substrate was fabricated through the combination of electrospinning and in situ chemical reduction. Due to the rough surface morphology and the intricate 3D structure, a high density of Raman "hotspots" was formed at the junctions of cross-linked nanofibers, resulting in excellent sensitivity to a probe molecule (4 aminothiophenol). The nanofibers were modified with l-cysteine to capture TNT molecules by the formation of a Meisenheimer complex, after which positively charged 4-ATP-labelled AgNPs were introduced to the system, which both generated more hotspots and led to a linear relationship between the TNT concentration and the SERS intensity of the labelled molecules. As a result, a good linear response ranging from 10-8 to 10-12 M was achieved, and the detection limit for TNT was as low as 2.05 * 10-13 M. This strategy demonstrates an ultra-sensitive approach for the detection of trace amounts of TNT, and a promising method for the detection of many other analogous explosives.

AB - Herein, we report a conformation switching-based fluorescence sensing scheme using dipeptide-based amidothioureas (azapeptides) that contain a folded beta turn structure. Amidothiourea is equipped at its two termini with an electron acceptor and an electron donor or two fluorophores, such that it exhibits enhanced exciplex or excimer emission because of the turn structure in which the two termini are brought into close proximity; on the other hand, it exhibits a dramatic ratiometric fluorescence response upon anion binding to the thiourea moiety because of the resultant extended conformation of the anion binding complex. PMID- 29168855 TI - High adjuvant activity of layered double hydroxide nanoparticles and nanosheets in anti-tumour vaccine formulations. AB - Effective adjuvants in anti-tumour vaccine formulations are very important in the development of new-generation vaccines. In this study, two layered double hydroxide (LDH) nanomaterial forms, i.e. nanoparticles (NPs) and nanosheets (NSs), were synthesised and examined as adjuvants to provoke the immune responses for anti-tumour purpose. Immunogen ovalbumin (OVA) delivered by both nanomaterials induced much stronger humoral and cell-medicated immune responses, together with an immune stimulant (TLR9 ligand CpG), as evidenced by higher levels of IgG1, IgG2a and interferon-gamma. By comparison, LDH NSs showed higher activity to promote specific antibody responses than LDH NPs but with a similar cell-mediated immune response. The mice immunised with OVA-CpG vaccines formulated with both nanomaterials showed stronger inhibition of the inoculated tumour growth and had a longer survival. Altogether, these data indicate that LDH NPs and NSs can be used as potential nanoadjuvants for efficient protein-based anti-tumour vaccines. PMID- 29168856 TI - Temperature dependence of photoluminescence and hydrogen bonding revealed for the first time in a templated borate family: synthesis, structure and properties of a pentaborate [Emmim][B5O6(OH)4]. AB - Herein, a templated borate, [Emmim][B5O6(OH)4] (denoted 1, Emmim = 1-ethyl-2,3 dimethylimidazolium), has been synthesized. It is unexpectedly observed that 1 exhibits a series of broadened luminescence curves from -183 to 75 degrees C, the emission intensities are measured as a decreasing function of temperature, and the line width of the PL emission is strongly enhanced when temperatures decrease below -100 degrees C. In addition to this, hydrogen bonding (H-B) in 1 with distinctly enlarging trends was observed as the temperature increased. The influence of temperature on H-Bs and physical properties was explored through single crystal X-ray diffraction analysis, theoretical calculations, PL, and dielectric constant test. The results indicate that the temperature can impact weak H-Bs interactions and the PL can be seen as a prober to the varying of structure such as H-Bs in borate crystal.

DFT calculations reveal a bond strength order of Cu-Cl > Cu-O/N ? CuCl. ESI-MS data reveal several small fragments from CBC, but oligomeric [Cu], [Cu], and [Cu] for non-zero in-source energies; MS data indicates the occurrence of several chemical processes, viz. splitting of the ligand, oligomerization, and redox reaction of alcohol to aldehyde and CuII to CuI. Gibbs free energies for the fragments were estimated using DFT. The magnetic susceptibility was modeled with the ferromagnetic coupling J(Cu-Cl2aCu) = +0.99(30) cm-1 and J'(pipi) = +0.35(16) cm-1 and g = 2.38(2). HF-EPR determined the anisotropic g-values, gx = 2.24, gy = 2.16, and gz = 2.09, and a hyperfine constant of Az = 450 G. DFT calculations from crystal structure data reveal a J(Cu-Cl2aCu) of +3.6 at 296 K and +4.1 cm-1 at 90 K that dominates the magnetic properties, whereas J'(pipi) = 0.04 cm-1 is negligibly small.

AB - Among older adults, falls are a leading cause of distress, pain, injury, loss of confidence, and ultimately, loss of independence and death. Previous studies in our laboratory have demonstrated that berry supplementation improves the age related declines in balance, muscle strength, and coordination that often lead to falls, even when initiated later in life. The purpose of this study was to explore the interaction between baseline motor performance and the daily intake of raspberry required to improve/preserve motor function. Aged male F344 (17 mo) rats were tested for baseline (pre-test) balance, muscle strength, and coordination, and divided into good, average, and poor performers based on their motor composite score. Rats in each category were fed with either a control, 1%, or 2% raspberry-supplemented diet for 8 weeks and then retested (post-test). Poor performers fed with 1% or 2% raspberry had higher post-test composite scores (p < 0.05), while 2% raspberry lowered post-test composite scores in the good performers (p < 0.05), compared to control-fed rats. 1% and 2% raspberry appeared to preserve the performance of good performers and improve the performance of poor performers on plank walking (p < 0.05), while 2% raspberry improved post test grip strength of the poor performers (p < 0.05). Additionally, rats with lower post-diet composite scores had higher levels of serum IL-1beta levels (r = 0.347, p < 0.05). These findings identified poor performers as being the most likely to benefit from daily consumption of 1/2-2 cups of raspberry to improve/preserve motor function. Therefore, increased raspberry consumption may reduce fall risk, extend independence, and improve quality of life in the aging population.

AB - Over the last few years, focused interest in aluminum has been heightened by recent studies regarding its health effects. Its possible relation with chronic diseases makes it convenient to address more in depth the reactivity of aluminum with biologically relevant molecules. The present work investigates the interaction of the aluminum ion with two synthetic RNAs, poly(rA) and poly(rU), through a detailed thermodynamic and kinetic study. The trivalent aluminum ion was kept in solution by complexation with the cacodylate anion, even at neutral pH, thus making the study with biological molecules feasible. The results obtained by spectrophotometry, circular dichroism, viscometry and thermal stability measurements indicate that aluminium strongly interacts with single and duplex RNA structures. The kinetic experiments point out that, even though cacodylate is required to keep the metal in solution, it actually inhibits the reaction of aluminum with RNA as it converts the metal into an unreactive dimer species. Notably, further interaction occurred in an excess of the aluminum/cacodylate complex, inducing aggregation of single-stranded RNAs. An analysis of the kinetic data has shown that the modes of aggregation of the two RNAs differ and such a difference can be ascribed to the diverse polynucleotide secondary structures. The observed stabilization of multiple-stranded systems by aluminum can serve as a model for future studies due to the interest aroused by this metal in the study of non-canonical nucleic acid structures.

AB - Advanced glycation endproducts (AGEs) are the harmful products of non-enzymatic reactions in foods formed during the heating process. In order to reduce the content of AGEs in foods, the inhibitory effect of different proportions of transglutaminase (TGase) and chitosan oligosaccharides (COS) on the AGEs of seabream fish meat sausage was studied. The results indicated that the TGase/COS ratio of 1 : 1 could inhibit the formation of AGEs, showing especially a decreased Nepsilon-carboxymethyl-lysine (CML) content and a twice higher inhibition rate (36.4%) than that by aminoguanidine (17.4%), a commonly effective positive inhibitor of AGEs. The data of lysine, fructosamine, and glucosamine contents, combined with sodium dodecyl sulfate-polyacrylamide gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analyses, demonstrated that cross-linking of proteins and glycosylation of glutamine induced by TGase and COS resulted in steric hindrance that inhibited glycation. These findings revealed that TGase catalyzed glycosylation with COS differently from general antioxidants had potential as an effective treatment to inhibit the formation of AGEs in fishery products. PMID- 29168863 TI - Structure characterization of a novel polysaccharide from Hericium erinaceus fruiting bodies and its immunomodulatory activities. AB - A novel polysaccharide fraction (HEP-S) was extracted and isolated from the fruiting bodies of Hericium erinaceus. Structural characterization revealed that HEP-S had an average molecular weight of 1.83 * 104 Da and consisted of rhamnose, fucose, mannose, glucose and galactose at a molar ratio of 1.47 : 0.93 : 1.36 : 8.68 : 4.08. Periodate oxidation-Smith degradation and NMR analysis showed that the main linkage types of HEP-S were composed of (1->)-alpha-d-Glc, (1->3,4) alpha-d-Glc, (1->6)-alpha-d-Gal, (1->3,4)-beta-d-Man, (1->3,6)-alpha-Rha and (1 >2)-beta-l-Fuc. The immunomodulatory assay indicated that HEP-S could significantly enhance the pinocytic and phagocytic capacity and promote the secretion of nitric oxide and pro-inflammatory cytokines by activating the corresponding mRNA and protein expression in RAW 264.7 cells involving a toll like receptor 2 membrane receptor. Besides, HEP-S was also found to improve the adaptive immune function by enhancing T and B lymphocyte proliferation and increasing the interleukin-2, interleukin-4 and interferon-gamma secretion in spleen lymphocytes. These results suggested that HEP-S could be used as a potential immunoregulatory agent in functional foods.

AB - Time-resolved photoelectron spectroscopy measurements combined with quantum chemistry and dynamics calculations allow unprecedented insight into the electronic relaxation mechanisms of photoexcited molecules in the gas-phase. In this Tutorial Review, we explain the essential concepts linking photoelectron spectroscopy measurements with electronic structure and how key features on the potential energy landscape are identified using quantum chemistry and quantum dynamics calculations. We illustrate how time-resolved photoelectron spectroscopy and theory work together using examples ranging in complexity from the prototypical organic molecule benzene to a pyrrole dimer bound by a weak N-Hpi interaction and the green fluorescent protein chromophore. PMID- 29168865 TI - Syntheses, crystal structures, DFT calculations, protein interaction and anticancer activities of water soluble dipicolinic acid-imidazole based oxidovanadium(iv) complexes. AB - Three novel water soluble neutral mononuclear oxidovanadium(iv) complexes 1-3, [VOLB2] (where H2L = dipicolinic acid (DPA) and B = imidazole (1)/1 methylimidazole (2)/1-allylimidazole (3)), were synthesized by the reaction of [VOL(H2O)2] with imidazole/1-methylimidazole/1-allylimidazole in ethanol. The complexes were thoroughly characterized by elemental analysis, IR, UV-Vis and EPR spectroscopy, magnetic susceptibility, cyclic voltammetry and single crystal X ray diffraction techniques. In all the complexes the vanadium(iv) centre assumes a distorted octahedral environment. All the three complexes have similar structures and contain a range of intramolecular interactions such as hydrogen bonding, C-Hpi, and pipi stacking dominating their supramolecular architectures. A thermal study of the complexes was carried out to analyze their stability. The energy of non-covalent interactions and frontier orbitals for the complexes were also calculated by DFT. In order to investigate the binding interactions and conformational changes of the secondary structure of bovine serum albumin (BSA) with the complexes, absorption, fluorimetric titration and circular dichroism measurements in aqueous medium were carried out. Molecular docking studies have also been carried out to understand the binding modes and interaction patterns of the oxidovanadium(iv) complexes with BSA. The anticancer activities of the ligand and complexes 1-3 were tested against the human hepatic carcinoma cell line Hep3B. The complexes showed prominent cytotoxicity towards cancer cells. PMID- 29168866 TI - Chemical composition and bioactive properties of the wild mushroom Polyporus squamosus (Huds.) Fr: a study with samples from Romania. AB - In Eastern Europe, wild mushrooms are widely collected in mountain areas and used for their medicinal properties or as healthy foods. This study aimed at determining the chemical composition (nutritional value, free sugars, organic acids, phenolic compounds, fatty acids and tocopherols) and bioactive properties (antioxidant, antimicrobial and antiquorum sensing) of wild Polyporus squamosus (Huds.) Fr from Romania. The results indicate that the fruiting bodies of P. squamosus are rich in carbohydrates (74.22 g per 100 g dw) and proteins (18.7 g per 100 g dw). Trehalose was the main free sugar, while malic acid was the organic acid detected in the highest amount (2.21 g per 100 g dw), and p hydroxybenzoic acid was the main phenolic compound. Among tocopherols, beta tocopherol was the most abundant form (114.7 MUg per 100 g dw). Additionally, regarding the fatty acids' pattern, polyunsaturated acids represent more than 57% of all fatty acids, followed by monounsaturated fatty acids (24.96%). The highest measured antioxidant effect of P. squamosus extract was found using the TBARS inhibition assay (EC50 = 0.22 mg mL-1), followed by the beta-carotene/linoleate assay (EC50 = 1.41 mg mL-1). A minimal inhibitory concentration of the tested extracts was obtained between 0.61-20.4 mg mL-1, while the bactericidal effect was achieved between 1.2-40.8 mg mL-1. Antibiofilm potential was obtained at all tested concentrations, and subinhibitory concentrations of the extract exhibited an antiquorum effect and reduced the formation of P. aeruginosa pili, which all together influenced the virulence of this bacterium. Due to the investigated bioactivities and compounds of P. squamosus and its well-balanced nutritional profile, this mushroom can be further used as a medicinal ingredient based on its antioxidative and antimicrobial potential. PMID- 29168867 TI - The protective effect of phloretin in osteoarthritis: an in vitro and in vivo study. AB - Osteoarthritis (OA) is a degenerative joint disease characterized by the degradation and inflammation of cartilage. Phloretin, a type of dihydrochalcone mainly found in apples and apple-derived products, has been reported to possess various potent biological effects such as antioxidant, anticancer, anti inflammatory, and immunomodulatory. However, the anti-inflammatory effects of phloretin on OA have not been reported. This study was aimed at assessing the effects of phloretin on human OA chondrocytes. Human OA chondrocytes were pretreated with phloretin (10, 30, and 100 MUM) for 2 h and subsequently stimulated with IL-1beta for 24 h. The production of NO, PGE2, TNF-alpha, and IL 6 was determined using the Griess reagent and ELISAs. The mRNA expression of COX 2, iNOS, MMP-3, MMP-13, and ADAMTS-5 was measured by real-time PCR. Changes in the protein expression of COX-2, iNOS, MMPs, ADAMTS, aggrecan, collagen-II, NF kappaB, and the PI3K/Akt signaling pathway were detected by western blotting. In this study, we found that phloretin significantly inhibited the IL-1beta-induced production of NO, PGE2, TNF-alpha, and IL-6, the expression of COX-2, iNOS, MMP 3, MMP-13, and ADAMTS-5, and the degradation of aggrecan and collagen-II in human OA chondrocytes. Furthermore, phloretin dramatically suppressed the IL-1beta stimulated phosphorylation of PI3K/Akt and activation of NF-kappaB in human OA chondrocytes. In addition, treatment with phloretin not only prevented the destruction of cartilage and the thickening of subchondral bone but also relieved synovitis in a mouse model of OA. Moreover, immunohistochemical results showed that phloretin significantly decreased the expression of MMP-13 and increased the expression of collagen-II in OA in mice. In conclusion, these results suggest that phloretin may be a potential agent for the treatment of OA. PMID- 29168868 TI - Structural elucidation and immunostimulatory activity of a new polysaccharide from Cordyceps militaris. AB - A new polysaccharide (CMPB90-1) was isolated from cultured Cordyceps militaris by alkaline extraction. The chemical structure of CMPB90-1 was determined by analysis of physicochemical and spectral data. The backbone of CMPB90-1 is composed of (1->6)-linked alpha-d-glucopyranosyl and (1->3)-linked alpha-d glucopyranosyl residues, with branching at O-6, which consists of (1->4)-linked beta-d-mannopyranosyl and (1->6)-linked alpha-d-glucopyranosyl residues, respectively. beta-d-Galactopyranosyl residues is the terminal unit. In vitro immunomodulatory assay revealed that CMPB90-1 promoted proliferation of splenic lymphocytes, enhanced cytotoxicity of NK cells and promoted lymphocyte secretion of the cytokine interleukin-2. Besides, CMPB90-1 upregulated T-cell subpopulation, strengthened phagocytosis function of macrophages and induced their M1 polarization. The mechanism of the effects might be due to the activation of TLR2, MAPK and NF-kappaB pathways. The results proposed that CMPB90 1 can be researched and developed as a new functional food. PMID- 29168869 TI - Amentoflavone improves cardiovascular dysfunction and metabolic abnormalities in high fructose and fat diet-fed rats. AB - Metabolic syndrome (MS) is a leading cause of mortality and morbidity in Western countries. Amentoflavone (AMF) is a polyphenolic compound which has been found to exhibit various biological activities. In this study, we investigated the protective effects of AMF against cardiovascular and liver dysfunction in high fructose and fat diet (HFFD)-induced MS rats. AMF could evidently inhibit the changes of general metabolic parameters, including body weight, fat mass, insulin level, and glucose tolerance activity. AMF markedly protected against cardiovascular dysfunction, as evidenced by a decrease of systolic blood pressure, left ventricular internal diameter in diastole (LVIDd) and left ventricular posterior wall thickness in diastole (LVPWd); increase of fractional shortening; and decrease of ejection fraction, relative wall thickness, estimated LV mass, cardiac stiffness and LV wet weight in HFFD-fed rats. AMF also inhibited the increase of aortic vasoconstriction in response to phenylephrine and increased relaxation in response to acetylcholine in HFFD-fed rats. AMF reversed the HFFD-induced decrease of nitrogen oxide level, increase of type 1 Ang II receptor (AT-1A) expression and decrease of AT-2A expression. AMF reduced histological and functional injury and lipid accumulation in livers in MS rats. AMF also inhibited HFFD-induced oxidative stress, as reflected by the decrease of thiobarbituric acid reactive substance content, increase of GSH level, increase of superoxide dismutase and catalase activities, and decrease of NADPH oxidase activities. In summary, we showed that AMF exhibited protective effects against cardiovascular dysfunction and liver injury in MS rats. Inhibition of the renin angiotensin system and oxidative stress contributes to cardiovascular and liver protective activities. Our data provide novel insights into the beneficial effects of AMF against MS. PMID- 29168870 TI - Hybrid compounds assembled from copper-triazole complexes and phosphomolybdic acid as advanced catalysts for the oxidation of olefins with oxygen. AB - Two hybrid compounds, namely [Cu(3atrz)4][PMoMoVO40] (1) and [Cu(3atrz)6][PMo12O40]2 (2), were synthesized through hydrothermal reactions of 3 amino-1,2,4-triazole (3atrz), phosphomolybdic acid (PMA) and appropriate copper salts. Crystal structure analysis reveals that compound 1 contains one dimensional Cu-3atrz chains. The unit of compound 2 contains a double calyx[3]arene-shaped hexamer, which is composed of six two-coordinated CuI atoms and six 3atrz ligands. Both compounds 1 and 2 present a three-dimensional hybrid structure, which is built by the self-assembly of Cu-3atrz clusters and Keggin type PMA units. The resulting hybrid compounds can act as highly efficient heterogeneous catalysts for the selective oxidation of olefins with molecular oxygen as the oxidant in the presence of a trace amount of tert-butyl hydroperoxide (t-BuOOH). Their excellent catalytic properties can be mainly attributed to the existence of stabilized CuI complexes with an appropriate chemical environment and a spacious structure, which can interact with t-BuOOH to form catalytic sites for the direct activation of O2. This work demonstrates that the hybrid compounds assembled from copper-3atrz complexes and phosphomolybdic acid may have great potential in molecular O2-mediated catalytic oxidation reactions, which can certainly build a platform for deep insight into the biologically relevant catalytic oxidation processes. PMID- 29168871 TI - Probing impaired neurogenesis in human brain organoids exposed to alcohol. AB - The fetal brain is highly vulnerable to ethanol exposure, which can trigger various long-term neuronal disabilities and cognitive dysfunctions. However, a comprehensive understanding of fetal brain development under ethanol exposure is challenging due to the limitations of animal models. Here, we propose a human induced pluripotent stem cell (hiPSC)-based 3D brain organoid model, and explore the mechanisms underlying neural dysfunctions in prenatal alcohol exposure (PAE) in vitro. Brain organoids were examined to resemble brain organogenesis in vivo at early stages during gestation, with specific features of neuronal differentiation, brain regionalization, and cortical organization. With ethanol exposure, the brain organoids displayed attenuated neurite outgrowth and skewed neural maturation. Transcriptome analysis identified a series of new markedly altered genes and enriched pathways, such as GSX2, RSPO2, and the Hippo signaling pathway. These genes or pathways, to our knowledge, were reported to be involved in ethanol-induced impaired neurogenesis for the first time. Our new findings might facilitate better understanding of the various postnatal neural disorders observed in individuals with PAE. PMID- 29168872 TI - Organoselenium compounds as mimics of selenoproteins and thiol modifier agents. AB - Selenium is an essential trace element for animals and its role in the chemistry of life relies on a unique functional group: the selenol (-SeH) group. The selenol group participates in critical redox reactions. The antioxidant enzymes glutathione peroxidase (GPx) and thioredoxin reductase (TrxR) exemplify important selenoproteins. The selenol group shares several chemical properties with the thiol group (-SH), but it is much more reactive than the sulfur analogue. The substitution of S by Se has been exploited in organic synthesis for a long time, but in the last 4 decades the re-discovery of ebselen (2-phenyl-1,2 benzisoselenazol-3(2H)-one) and the demonstration that it has antioxidant and therapeutic properties has renovated interest in the field. The ability of ebselen to mimic the reaction catalyzed by GPx has been viewed as the most important molecular mechanism of action of this class of compound. The term GPx like or thiol peroxidase-like reaction was previously coined in the field and it is now accepted as the most important chemical attribute of organoselenium compounds. Here, we will critically review the literature on the capacity of organoselenium compounds to mimic selenoproteins (particularly GPx) and discuss some of the bottlenecks in the field. Although the GPx-like activity of organoselenium compounds contributes to their pharmacological effects, the superestimation of the GPx-like activity has to be questioned. The ability of these compounds to oxidize the thiol groups of proteins (the thiol modifier effects of organoselenium compounds) and to spare selenoproteins from inactivation by soft-electrophiles (MeHg+, Hg2+, Cd2+, etc.) might be more relevant for the explanation of their pharmacological effects than their GPx-like activity. In our view, the exploitation of the thiol modifier properties of organoselenium compounds can be harnessed more rationally than the use of low mass molecular structures to mimic the activity of high mass macromolecules that have been shaped by millions to billions of years of evolution. PMID- 29168873 TI - Throughput enhancement of parallel step emulsifier devices by shear-free and efficient nozzle clearance. AB - Step emulsification is an attractive method for production of monodisperse drops. Its main advantage is the ability to parallelize many step emulsifier nozzles to achieve high production rates. However, step emulsification is sensitive to any obstructions at the nozzle exit. At high production rates, drops can accumulate at nozzle exits, disturb the formation of subsequent drops and impair monodispersity. As a result, parallelized step emulsifier devices typically do not work at maximum productivity. Here a design is introduced that parallelizes hundreds of step emulsifier nozzles, and effectively removes drops from the nozzle exits. The drop clearance is achieved by an open collecting channel, and is aided by buoyancy. Importantly, this clearance method avoids the use of a continuous phase flow for drop clearance and hence no shear is applied on the forming drops. The method works well for a wide range of drops, sizing from 30 to 1000 MUm at production rates of 0.03 and 10 L per hour and achieved by 400 and 120 parallelized nozzles respectively. PMID- 29168874 TI - Bioreactor model of neuromuscular junction with electrical stimulation for pharmacological potency testing. AB - In vitro models of the neuromuscular junction (NMJ) are emerging as a valuable tool to study synaptogenesis, synaptic maintenance, and pathogenesis of neurodegenerative diseases. Many models have previously been developed using a variety of cell sources for skeletal muscle and motoneurons. These models can advanced by integrating beneficial features of the native developmental milieu of the NMJ. We created a functional in vitro model of NMJ by bioreactor cultivation of transdifferentiated myocytes and stem cell-derived motoneurons, in the presence of electrical stimulation. In conjunction with a coculture medium, electrical stimulation resulted in improved maturation and function of motoneurons and myocytes, as evidenced by mature cellular structures, increased expression of neuronal and muscular genes, clusterization of acetylcholine receptors (AChRs) in the vicinity of motoneurons, and the response to glutamate stimulation. To validate the model and demonstrate its utility for pharmacological testing, we documented the potency of drugs that affect key pathways during NMJ signal transduction: (i) acetylcholine (ACh) synthesis, (ii) ACh vesicular storage, (iii) ACh synaptic release, (iv) AChR activation, and (v) ACh inactivation in the synaptic cleft. The model properly responded to the drugs in a concentration-dependent manner. We thus propose that this in vitro model of NMJ could be used as a platform in pharmacological screening and controlled studies of neuromuscular diseases. PMID- 29168875 TI - Appreciation of symmetry in natural product synthesis. AB - Covering: 2012 to June 2017This review aims to show that complex natural product synthesis can be streamlined by taking advantage of molecular symmetry. Various strategies to construct molecules with either evident or hidden symmetry are illustrated. Insights regarding the origins and adjustments of these strategies as well as inspiring new methodological developments are deliberated. When a symmetric strategy fails, the corresponding reason is analysed and an alternative approach is briefly provided. Finally, the importance of exploiting molecular symmetry and future research directions are discussed. PMID- 29168876 TI - A compartmentalized microfluidic chip with crisscross microgrooves and electrophysiological electrodes for modeling the blood-retinal barrier. AB - The interconnection of different tissue-tissue interfaces may extend organ-on chips to a new generation of sophisticated models capable of recapitulating more complex organ-level functions. Single interfaces are largely recreated in organ on-chips by culturing the cells on opposite sides of a porous membrane that splits a chamber in two or by connecting the cells of two adjacent compartments through microchannels. However, it is difficult to interconnect more than one interface using these approaches. To address this challenge, we present a novel microfluidic device where cells are arranged in parallel compartments and are highly interconnected through a grid of microgrooves, which facilitates paracrine signaling and heterotypic cell-cell contact between multiple tissues. In addition, the device includes electrodes on the substrate for the measurement of transepithelial electrical resistance (TEER). Unlike conventional methods for measuring the TEER where electrodes are on each side of the cell barrier, a method with only electrodes on the substrate has been validated. As a proof-of concept, we have used the device to mimic the structure of the blood-retinal barrier by co-culturing primary human retinal endothelial cells (HREC), a human neuroblastoma cell line (SH-SY5Y), and a human retinal pigment epithelial cell line (ARPE-19). Cell barrier formations were assessed by a permeability assay, TEER measurements, and ZO-1 expression. These results validate the proposed microfluidic device with microgrooves as a promising in vitro tool for the compartmentalization and monitoring of barrier tissues. PMID- 29168877 TI - Full-angle tomographic phase microscopy of flowing quasi-spherical cells. AB - We report a reliable full-angle tomographic phase microscopy (FA-TPM) method for flowing quasi-spherical cells along microfluidic channels. This method lies in a completely passive optical system, i.e. mechanical scanning or multi-direction probing of the sample is avoided. It exploits the engineered rolling of cells while they are flowing along a microfluidic channel. Here we demonstrate significant progress with respect to the state of the art of in-flow TPM by showing a general extension to cells having almost spherical shapes while they are flowing in suspension. In fact, the adopted strategy allows the accurate retrieval of rotation angles through a theoretical model of the cells' rotation in a dynamic microfluidic flow by matching it with phase-contrast images resulting from holographic reconstructions. So far, the proposed method is the first and the only one that permits to get in-flow TPM by probing the cells with full-angle, achieving accurate 3D refractive index mapping and the simplest optical setup, simultaneously. Proof of concept experiments were performed successfully on human breast adenocarcinoma MCF-7 cells, opening the way for the full characterization of circulating tumor cells (CTCs) in the new paradigm of liquid biopsy. PMID- 29168878 TI - Quercetin and fisetin enhanced the small intestine cellular uptake and plasma levels of epi-catechins in in vitro and in vivo models. AB - Quercetin and fisetin, known as catechol-containing flavonoids, could positively affect the absorption of catechins due to their strong affinity for catechol-O methyl transferase (COMT), which can methylate and cause the excretion of catechins. The current study examined the effect of quercetin and fisetin on the absorption of epi-catechins (ECs) by using a Caco-2 cell line and an in vivo model. The intestinal transport of total catechins by Caco-2 cells was enhanced from 1.3- to 1.6-fold and 1.4- to 1.7-fold by adding quercetin and fisetin, respectively, compared to the control. It was even higher in the treatment with a mixture of quercetin and fisetin. While EC had the highest value of intestinal transport (169% of the control) in 10% quercetin treatment, EGC (235%), EGCG (244%), and ECG (242%) were significantly transported in the treatment with a 5% mixture of quercetin and fisetin (p < 0.05). In an in vivo pharmacokinetic study, the values of the area under the plasma concentration-time curve (AUC, ng h mL-1) were also higher in rats orally administered EGCG with 10% quercetin (365.5 +/- 25.5) or 10% fisetin (825.3 +/- 46.7) than in those administered EGCG only (111.3 +/- 13.1). Methylated quercetin and methylated fisetin were determined to be m/z 317.24 and m/z 301.25 [M + H]+ with their own product ions, respectively. The results indicate that quercetin or fisetin is superior to ECs for methylation by COMT. PMID- 29168879 TI - 1p36 deletion results in a decrease in glycosaminoglycans which is associated with aggressiveness in neuroblastic tumors. AB - Despite our deep understanding of neuroblastic tumors, some patients still suffer treatment failure, so pre-treatment risk stratification still requires improvement and the search for new therapeutic targets must continue. Here we correlated prognostic clinical and biological features of neuroblastic tumors with the density of extracellular matrix glycosaminoglycans (the main components of the extracellular matrix 'ground substance'), in nearly 400 primary samples. We also studied the relationship between the density of extracellular matrix glycosaminoglycans and the expression of B3GALT6, an enzyme required for their synthesis. We associated a decrease in glycosaminoglycans with neuroblastomas that were histopathologically poorly-differentiated or undifferentiated, as well as with metastatic disease, and 1p36 deleted tumors. This decrease in glycosaminoglycans was also related to abnormal nuclear B3GALT6 expression in neuroblastic cells. These findings point towards the importance of the ground substance in the aggressiveness of neuroblastic tumors, which should therefore be considered when developing novel therapies for treating neuroblastomas. PMID- 29168880 TI - Cost-Effectiveness of a Care Transitions Program in a Multimorbid Older Adult Cohort. AB - BACKGROUND/OBJECTIVES: Facing penalties for preventable 30-day hospital readmissions, many provider groups have implemented programs to remedy this problem, but the cost efficacy and value of such programs are not well delineated. The objective was to compare total cost of care over 30 days of individuals enrolled in the Mayo Clinic Care Transitions (MCCT) program and individuals not enrolled. DESIGN: Retrospective cohort study using secondary data analysis of a previously published cohort study. SETTING: Mayo Clinic, Rochester, Minnesota. PARTICIPANTS: MCCT participants (n = 363) and individuals in a propensity-matched referent cohort (n = 365). INTERVENTION: MCCT program enrollment. MEASUREMENTS: The primary outcome was total cost of care over 30 days after hospital discharge. A 2-part modeling strategy was used to analyze 30-day costs: whether individuals had non-zero costs during the 30 days after discharge and a generalized linear model for individuals who incurred costs. Potential heterogeneous effects of the MCCT program were examined according to decile of 30 day costs using quantile regression. RESULTS: Mean age was 83 in both groups. Adjusted mean 30-day cost after hospitalization was $3,363 (95% confidence interval (CI) = $2,512-4,213) in the MCCT group and $4,161 (95% CI = $3,096 5,226) in the control group (P = .25). Cost savings of $2,744 (P = .008) at the eighth decile and $3,388 (P = .20) at the ninth decile were demonstrated. Thus, the only statistically significant differences were in the post hoc subgroup analysis in the highest-cost subgroups. CONCLUSION: We did not find a difference in overall mean costs between the MCCT group and the control group, although intervention participants in the upper deciles of costs appeared to experience lower costs than controls. A larger study cohort might better determine the value of the intervention. PMID- 29168881 TI - Quality of life in a randomized trial of early closure of temporary ileostomy after rectal resection for cancer (EASY trial). AB - BACKGROUND: A temporary ileostomy may reduce symptoms from anastomotic leakage after rectal cancer resection. Earlier results of the EASY trial showed that early closure of the temporary ileostomy was associated with significantly fewer postoperative complications. The aim of the present study was to compare health related quality of life (HRQOL) following early versus late closure of a temporary ileostomy. METHODS: Early closure of a temporary ileostomy (at 8-13 days) was compared with late closure (at more than 12 weeks) in a multicentre RCT (EASY) that included patients who underwent rectal resection for cancer. Inclusion of participants was made after index surgery. Exclusion criteria were signs of anastomotic leakage, diabetes mellitus, steroid treatment, and signs of postoperative complications at clinical evaluation 1-4 days after rectal resection. HRQOL was evaluated at 3, 6 and 12 months after resection using the European Organisation for Research and Treatment of Cancer (EORTC) questionnaires QLQ-C30 and QLQ-CR29 and Short Form 36 (SF-36(r)). RESULTS: There were 112 patients available for analysis. Response rates of the questionnaires were 82-95 per cent, except for EORTC QLQ-C30 at 12 months, to which only 54-55 per cent of the patients responded owing to an error in questionnaire distribution. There were no clinically significant differences in any questionnaire scores between the groups at 3, 6 or 12 months. CONCLUSION: Although the randomized study found that early closure of the temporary ileostomy was associated with significantly fewer complications, this clinical advantage had no effect on the patients' HRQOL.

AB - BACKGROUND/OBJECTIVES: Frailty in older adults predicts dependence and mortality and is a major challenge for healthcare systems in countries with rapidly aging populations. Little is known about frailty in China. We investigated the prevalence and associated risk factors of frailty in older adults in China. DESIGN: Cross-sectional. SETTING: Data were obtained from the China Comprehensive Geriatric Assessment Study, conducted in 2011-12, which was the first uniform comprehensive assessment system adopted in China. PARTICIPANTS: Older adults from 7 cities were selected based on well-established cluster, stratification, and random selection statistical sampling techniques (N = 5,844). MEASUREMENTS: The Comprehensive Geriatric Assessment-Frailty Index was measured based on demographic characteristics, physical health, physical function, living behavior and social function, mental health, and cognitive function. RESULTS: The overall weighted prevalence of frailty was 9.9%: 12.7% in southwestern China, 11.0% in northern China, 5.9% in northwestern China, 5.0% in south-central China, 2.5% in eastern China, and 2.3% in northeastern China. The prevalence of frailty increased with age and was significantly higher in women and those living in rural areas. After adjusting for sex, age, area, region, and education, activity of daily living impairment was the strongest risk factor for frailty. Chronic diseases, depression, poor lifestyle, and geriatric syndromes were also independent risk factors. CONCLUSION: Our study provides epidemiological characteristics and the risk factors of frailty in China; the findings indicate greater regional disparities. Efforts to promote physical, psychological, and social health in older adults are a core objective of health policy, especially in women and those living in rural areas. PMID- 29168882 TI - Fibroblast growth factor 2 regulates activity and gene expression of human post mitotic excitatory neurons. AB - Many neuropsychiatric disorders are thought to result from subtle changes in neural circuit formation. We used human embryonic stem cells and induced pluripotent stem cells (hiPSCs) to model mature, post-mitotic excitatory neurons and examine effects of fibroblast growth factor 2 (FGF2). FGF2 gene expression is known to be altered in brain regions of major depressive disorder (MDD) patients and FGF2 has anti-depressive effects in animal models of depression. We generated stable inducible neurons (siNeurons) conditionally expressing human neurogenin-2 (NEUROG2) to generate a homogenous population of post-mitotic excitatory neurons and study the functional as well as the transcriptional effects of FGF2. Upon induction of NEUROG2 with doxycycline, the vast majority of cells are post mitotic, and the gene expression profile recapitulates that of excitatory neurons within 6 days. Using hES cell lines that inducibly express NEUROG2 as well as GCaMP6f, we were able to characterize spontaneous calcium activity in these neurons and show that calcium transients increase in the presence of FGF2. The FGF2-responsive genes were determined by RNA-Seq. FGF2-regulated genes previously identified in non-neuronal cell types were up-regulated (EGR1, ETV4, SPRY4, and DUSP6) as a result of chronic FGF2 treatment of siNeurons. Novel neuron-specific genes were also identified that may mediate FGF2-dependent increases in synaptic efficacy including NRXN3, SYT2, and GALR1. Since several of these genes have been implicated in MDD previously, these results will provide the basis for more mechanistic studies of the role of FGF2 in MDD. PMID- 29168884 TI - Transformation of a Geriatric Department in China. AB - China has the world's largest elderly population, and the oldest-old population, with a current disability rate greater than 50%, will triple in the next 35 years. The field of geriatrics is young, because almost all geriatric departments were established after 2000, and so faces many challenges. Management of diseases and hospital care is the focus. Senior physicians were trained in other subspecialties, such as pulmonary or cardiology, and junior physicians entered geriatrics departments as masters or doctorate students after medical school. The inadequacy of post-acute and long-term care facilities has caused long hospital stays. There are no national systematic geriatric training programs, national board examinations, or qualifications in geriatrics. These challenges were used as a framework for guiding changes in the Department of Geriatrics at West China Hospital, Sichuan University. These changes have included international experiences and collaboration for physicians and nurses, revision of departmental conferences, and special training for a unique group of caregivers called hugong (untrained caregivers hired by families to be at the bedside of hospitalized individuals). The most significant yet challenging part of the transformation has been to develop and modify Western-based geriatric models of care (e.g., Acute Care of the Elderly unit, delirium prevention and management models, palliative care). Lastly, the department established Tianxia (in the sky) Doctors, an internet-based platform to connect the department's interdisciplinary team to other hospitals, nursing institutions, home-based care service stations, community health service centers, and pharmacies throughout the region. PMID- 29168886 TI - Phytochemical profiling of anti-inflammatory Lavandula extracts via RP-HPLC-DAD QTOF-MS and -MS/MS: Assessment of their qualitative and quantitative differences. AB - As for other aromatic plants, there are many analytical methods for the determination of volatile compounds in lavender essential oils. Alternatively, in this study RP-HPLC-DAD-QTOF-MS was used for the profiling of the phytochemical constituents of hydromethanolic extracts of L. stoechas and L. dentata, which were obtained by pressurized liquid extraction. The spectrometric data revealed complex profiles constituted of a wide range of polar and semi-polar phytochemicals, mainly, phenolic compounds (68). Most phenolic compounds (55) have not been previously reported in Lavandula; such is the case of caffeic acid based oligomers. Moreover, the analytical method was validated for the determination of phenolic compounds. Our findings showed both qualitative and quantitative differences between the extracts. In this sense, while hydroxycinnamic acids made up the largest class in both extracts, flavones were the most abundant class, accounting for 10.44 g (L. dentata) and 4.85 g (L. stoechas) per 100 g of dry extract. In conclusion, this analytical method provided essential information about the phytochemical composition of the studied medicinal plants, revealing novel constituents that were probably hidden for others. In addition, these results may help to understand the anti-inflammatory properties of these extracts. PMID- 29168885 TI - Distribution of peripheral dendritic cells in patients with HBV infection or spleen and kidney deficiency. AB - Spleen and kidney deficiency syndrome (SKD), a Traditional Chinese Medicine (TCM) syndrome, is the fundamental mechanisms of TCM. We aim to investigate the distribution of peripheral dendritic cells (DCs) in HBV patients with SKD or non SKD. Peripheral venous blood from patients with HBV infection and healthy volunteers was collected to extract PBMC, and flow cytometry assay was used to measure the distribution of DCs subsets, including myeloid dendritic cells (mDCs) and plasmacytoid dendritic cells (pDCs). For the number of pDCs, it was higher in control group and non-SKD group, compared with HBV infection group and SKD group, respectively. For the number of mDCs, it was higher in control group and the non SKD group compared to SKD group, while in control group it was higher than both HBeAg positive group and negative group. The number of pDCs in control group and chronic hepatitis B group were higher than HBVcarrier group, and it was higher in control group than both immune tolerance group and inactive group, while in immune clearance group it was higher than immune tolerance group and inactve group. The number of mDCs in control group and immune clearance group were higher than that of immune tolerance group. There was an obvious correlation between TCM syndromes and immune function in HBV infected patients, the number of pDCs and mDCs of the SKD group was lower than that in non-SKD group. These results provide a new insight into scientific evidence that TCM probably be based. PMID- 29168887 TI - Implications of WHO Guideline on Sugars for dental health professionals. AB - The burden of oral disease is high in populations across the world. This is because of high consumption of free sugars. The WHO Guideline on Sugars Intake for Adults and Children recommended limiting free sugars to no more than 5% energy intake to protect oral health throughout the life-course. The objectives of this paper are to consider the implications of the Guideline for dental health practice and to advocate use of the common risk factor approach when providing dietary advice. As part of a broad range of actions needed to reduce free sugars intake, improved education for dental health professionals and supporting patients to eat less free sugars are key actions for the dental profession. All dental health professionals should have the skills and confidence to provide their patients with healthier eating advice, including how to limit free sugars intake. It is therefore important that dental health professionals receive adequate education in diet and nutrition, and there is a need for dental educational regulating bodies to define the content of the dental curriculum with respect to nutrition. All patients, or their parents or carers, should receive dietary advice to reduce free sugars within the context of a healthy diet for the prevention of all NCDs. Dietary advice should: (i) focus on reducing the amount of free sugars consumed; (ii) be tailored according to the patient's body mass status (eg underweight, overweight, normal weight); (iii) encourage the consumption of fresh fruits and vegetables, nuts, seeds, and wholegrain starch rich foods; (iv) discourage the consumption of foods high in saturated fat and salt; and (v) discourage the consumption of all drinks containing free sugars. The dental health professional has an opportunity to support patients to reduce their intake of free sugars-such advice and support will have positive impacts beyond the mouth. PMID- 29168888 TI - Apparent seronegative maternal shingles with post-natal mother-to-baby transmission of varicella zoster virus. AB - We present an unusual case of varicella zoster (VZ) virus IgG negative, yet clinically apparent, maternal shingles, which prompted the administration of VZ immunoglobulin to the newborn. The mother had no previous VZ vaccination. Eleven days later the baby developed a primary VZ infection, with only mild disease, likely as a result of the VZ immunoglobulin. The variable sensitivity of VZV IgG specific assays is well-recognized. Thus, the ability of this particular VZV IgG assay to detect both maternal and infant VZV IgG, post-natally, suggests that the earlier VZV IgG negative results were due to lower circulating levels of maternal antibody. PMID- 29168889 TI - Acute viral infections of the central nervous system, 2014-2016, Greece. AB - In order to investigate the viral etiology of acute infections of central nervous system (CNS), multiplex and single PCRs combined with serology for arboviruses were applied on samples from 132 hospitalized patients in Greece during May 2014 December 2016. A viral pathogen was detected in 52 of 132 (39.4%) cases with acute CNS infection. Enteroviruses predominated (15/52, 28.8%), followed by West Nile virus (9/52, 17.3%). Phleboviruses, varicella-zoster virus, and Epstein-Barr virus accounted for 15.4%, 13.5%, and 11.5% of the cases, respectively. The study gives an insight into the etiology of viral CNS infections in a Mediterranean country, where arboviruses should be included in the differential diagnosis of acute CNS infections. PMID- 29168890 TI - Toward improved analysis of concentration data: Embracing nondetects. AB - Various statistical tests on concentration data serve to support decision-making regarding characterization and monitoring of contaminated media, assessing exposure to a chemical, and quantifying the associated risks. However, the routine statistical protocols cannot be directly applied because of challenges arising from nondetects or left-censored observations, which are concentration measurements below the detection limit of measuring instruments. Despite the existence of techniques based on survival analysis that can adjust for nondetects, these are seldom taken into account properly. A comprehensive review of the literature showed that managing policies regarding analysis of censored data do not always agree and that guidance from regulatory agencies may be outdated. Therefore, researchers and practitioners commonly resort to the most convenient way of tackling the censored data problem by substituting nondetects with arbitrary constants prior to data analysis, although this is generally regarded as a bias-prone approach. Hoping to improve the interpretation of concentration data, the present article aims to familiarize researchers in different disciplines with the significance of left-censored observations and provides theoretical and computational recommendations (under both frequentist and Bayesian frameworks) for adequate analysis of censored data. In particular, the present article synthesizes key findings from previous research with respect to 3 noteworthy aspects of inferential statistics: estimation of descriptive statistics, hypothesis testing, and regression analysis.

PMID- 29168891 TI - Effects of sediment resuspension on the oxidation of acid-volatile sulfides and release of metals (iron, manganese, zinc) in Pescadero estuary (CA, USA). AB - Bar-built estuaries are unique ecosystems characterized by the presence of a sandbar barrier, which separates the estuary from the ocean for extended periods and can naturally reopen to the ocean with heavy rainfall and freshwater inflows. The physical effects associated with the transition from closed to open state, specifically water mixing and sediment resuspension, often indirectly worsen water quality conditions and are suspected to drive near-annual fish kills at the Pescadero estuary in northern California. The effects of sediment acid-volatile sulfide (AVS) oxidation, specifically oxygen depletion, acidification, and metal release, are believed to aggravate water conditions for fish but remain poorly understood. We performed slurry incubations containing sediment from 4 sites in the Pescadero estuary, representing a gradient from the Pacific Ocean to freshwater tributaries. We measured near-maximum rates of aqueous hydrogen sulfide oxidation, sediment AVS oxidation, sulfate production, and acidification, as well as near-maximum release rates of iron (Fe), manganese (Mn), and zinc (Zn) to the water column. We estimated AVS oxidation rates of 8 to 21 mmol S kg-1 d-1 , which were 3 orders of magnitude higher than aqueous hydrogen sulfide oxidation rates, 6 to 26 MUmol S kg-1 d-1 . We suggest that aqueous hydrogen sulfide cannot be responsible for the observed kills because of low concentrations and minimal oxidative effects on pH and metal concentrations. However, the oxidative effects of AVS are potentially severe, decreasing pH to strongly acidic levels and releasing aqueous Fe, Mn, and Zn concentrations up to 11.2 mM, 0.46 mM, and 88 MUM, respectively, indicating a potential role in worsening water conditions for fish in the Pescadero estuary.

AB - Defective gut immune reactions have been implicated in the development of atopic dermatitis (AD), whereas oral tolerance (OT), that is, the immune unresponsiveness induced by oral antigen administration, protects mice against AD. To investigate this protective role of OT, the transcriptomic profiles of skin were obtained by RNA sequencing from mice that were epicutaneously sensitized, orally tolerized prior to epicutaneous sensitization, or neither (control). Oral tolerance inhibited the upregulation of keratin- and allergic inflammation-associated genes that occurred in the epicutaneously sensitized group. Compared to the controls, mice that were orally tolerized and epicutaneously sensitized showed an upregulation of genes that regulate inflammation or keratinocyte differentiation. Knocking down two of those genes, SCGB1A1 and TSC22D3, upregulated Th2 inflammatory mediators and downregulated a cornified cell envelope-related gene. Based on our findings, OT may protect skin against allergic inflammation by promoting the expression of genes that regulate Th2 inflammatory responses and skin barrier function. PMID- 29168892 TI - Functional properties of dopamine transporter oligomers after copper linking. AB - Although it is universally accepted that dopamine transporters (DATs) exist in monomers, dimers and tetramers (i.e. dimers of dimers), it is not known whether the oligomeric organization of DAT is a prerequisite for its ability to take up dopamine (DA), or whether each DAT protomer, the subunit of quaternary structure, functions independently in terms of DA translocation. In this study, copper phenanthroline (CuP) was used to selectively target surface DAT: increasing concentrations of CuP gradually cross-linked natural DAT dimers in LLC-PK1 cells stably expressing hDAT and thereby reduced DA uptake functionality until all surface DATs were inactivated. DATs that were not cross-linked by CuP showed normal DA uptake with DA Km at ~ 0.5 MUM and DA efflux with basal and amphetamine induced DA efflux as much as control values. The cocaine analog 2beta carbomethoxy-3beta-[4-fluorophenyl]-tropane (CFT) was capable to bind to copper cross-linked DATs, albeit with an affinity more than fivefold decreased (Kd of CFT = 109 nM after cross-linking vs 19 nM before). A kinetic analysis is offered describing the changing amounts of dimers and monomers with increasing [CuP], allowing the estimation of dimer functional activity compared with a DAT monomer. Consonant with previous conclusions for serotonin transporter and NET that only one protomer of an oligomer is active at the time, the present data indicated a functional activity of the DAT dimer of 0.74 relative to a monomer. PMID- 29168894 TI - Fluid mixing in droplet-based microfluidics with T junction and convergent divergent sinusoidal microchannels. AB - To explore and utilize the advantages of droplet-based microfluidics, hydrodynamics, and mixing process within droplets traveling though the T junction channel and convergent-divergent sinusoidal microchannels are studied by numerical simulations and experiments, respectively. In the T junction channel, the mixing efficiency is significantly influenced by the twirling effect, which controls the initial distributions of the mixture during the droplet formation stage. Therefore, the internal recirculating flow can create a convection mechanism, thus improving mixing. The twirling effect is noticeably influenced by the velocity of the continuous phase; in the sinusoidal channel, the Dean vortices and droplet deformation are induced by centrifugal force and alternative velocity gradient, thus enhancing the mixing efficiency. The best mixing occurred when the droplet size is comparable with the channel width. Finally, we propose a unique optimized structure, which includes a T junction inlet joined to a sinusoidal channel. In this structure, the mixing of fluids in the droplets follows two routes: One is the twirling effect and symmetric recirculation flow in the straight channel. The other is the asymmetric recirculation and droplet deformation in the winding and variable cross-section. Among the three structures, the optimized structure has the best mixing efficiency at the shortest mixing time (0.25 ms). The combination of the twirling effect, variable cross-section effect, and Dean vortices greatly intensifies the chaotic flow. This study provides the insight of the mixing process and may benefit the design and operations of droplet-based microfluidics. PMID- 29168895 TI - Epigenetics as a Driver of Developmental Origins of Health and Disease: Did We Forget the Fathers? AB - What are the effects of our environment on human development and the next generation? Numerous studies have provided ample evidence that a healthy environment and lifestyle of the mother is important for her offspring. Biological mechanisms underlying these environmental influences have been proposed to involve alterations in the epigenome. Is there enough evidence to suggest a similar contribution from the part of the father? Animal models provide proof of a transgenerational epigenetic effect through the paternal germ line, but can this be translated to humans? To date, literature on fathers is scarce. Human studies do not always incorporate appropriate tools to evaluate paternal influences or epigenetic effects. In reviewing the literature, I stress the need to explore and recognize paternal contributions to offspring's health within the Developmental Origins of Health and Disease hypothesis, and coin this new concept the Paternal Origins of Health and Disease paradigm (POHaD). A better understanding of preconceptional origins of disease through the totality of paternal exposures, or the paternal exposome, will provide evidence-based public health recommendations for future fathers. PMID- 29168896 TI - Healing of self-inflicted thermal injury of palatal mucosa by low-level laser therapy. AB - Self-inflicted injury to oral mucosa is a rare entity. These injuries can be premeditated, accidental, or can result from an abnormal habit. These uncommon gingival injuries can sometimes test the clinician's diagnostic abilities as well as treatment planning skills. In conventional treatment, removal of etiology and application of topical drugs is usually sufficient for healing. However, some cases require alternative or adjunctive wound healing methods. Low-level laser therapy (LLLT) has been reported to be effective in pain management and improvement in wound healing through promotion, fortification, and commissioning of cellular cycle to generate productive and substitute cells. This report presents a case of 25-year-old female with complaints of a painful, nonhealing wound on the palate for last 6 months. She had an unusual habit of keeping burning matchsticks in her mouth. Although she had quit the habit 2 months ago after psychiatric counseling, the wound on her palate did not show any improvement in symptoms. Based on the history and clinical findings, diagnosis of chronic wound by self-inflicted thermal injury was made. LLLT was administered on the wound every 48 hours for next 10 days. The burn wound healed completely after five applications of LLLT. PMID- 29168897 TI - Early socioeconomic conditions and severe tooth loss in middle-aged Costa Ricans. AB - OBJECTIVE: A wide literature shows a strong social gradient in tooth loss according to income, education and occupation, in both developed and developing countries. It has been shown associations between tooth loss and parental education and occupation, independently of adult conditions. To explore the role of early socioeconomic circumstances on tooth loss, we used a lifecourse model. We analysed the direct and indirect links between early socioeconomic conditions and severe adult tooth loss. METHODS: We used the Costa Rican Longevity and Healthy Aging Study 1945-1955 Retirement Cohort, a nationally representative longitudinal survey of Costa Rican residents born between 1945 and 1955. We used imputed data on 2796 individuals. Principal component analyses were run to integrate measures approaching the material circumstances during childhood and adulthood. We additionally examined the role of adult health behaviours and education level as potential mediators in the multivariable regression. RESULTS: Early socioeconomic conditions were found strongly associated with severe tooth loss; 72.4% of the people who experienced the most deprived socioeconomic conditions during childhood (quartile 1) had severe tooth loss at the time of the interview; vs 43.3% in quartile 4 (most advantaged). This link diminished after adjustment for adult mediators. However, it remained a significant determinant of severe tooth loss in the final model. CONCLUSION: The lifecourse model allowed to highlight that early socioeconomic conditions could have long-term consequences on severe tooth loss in middle ages via both direct and indirect mechanisms. PMID- 29168898 TI - Association of p16 (CDKN2A) polymorphisms with the development of HPV16-related precancerous lesions and cervical cancer in the Greek population. AB - The tumor suppressor protein p16 plays a fundamental role in cell cycle regulation and exerts a protective effect against tumor growth. Two different polymorphisms at positions 540 and 580 at the 3'UTR of exon 3 of p16 gene are implicated in several types of cancer, while their role in cervical cancer development remains rather vague. In the present study, we investigated for the impact of p16 genotypes/haplotypes on patients' vulnerability to cervical disease and examined whether these factors can be used as progression markers in the Greek population. A total of 96 HPV16 positive samples and histologically confirmed as LSIL (42 samples), HSIL (44 samples), and cervical cancer cases (10 samples) along with 50 control cases were tested. The identification of p16 polymorphisms was performed by PCR-RFLP methodology. The present analysis revealed that women with p16 540 CG/GG genotype are at a 2.7-fold higher risk of developing HPV16-associated HSIL (OR = 2.7, 95%CI: 1.01-6.6, P = 0.028). The G allele can be regarded as a risk factor of developing HSIL in the Greek population (OR = 2.7, 95%CI: 1.2-5.9, P = 0.012). Moreover, p16 polymorphism C580T is not associated with the growth of cervical lesion in Greek patients, while 540G/580C haplotype can be regarded as a risk haplotype of developing HSIL (OR = 3.67, 95%CI: 1.56-8.6, P = 0.0019). Our results demonstrated that p16 C540G polymorphism influence patients' susceptibility to more severe dysplasia and consequently this polymorphism could potentially emerge as a valuable biomarker for HSIL development in the Greek population. PMID- 29168899 TI - Global scales for cognitive screening in Parkinson's disease: Critique and recommendations. AB - BACKGROUND: Cognitive impairment is a common nonmotor manifestation of Parkinson's disease, with deficits ranging from mild cognitive difficulties in 1 or more of the cognitive domains to severe dementia. The International Parkinson and Movement Disorder Society commissioned the assessment of the clinimetric properties of cognitive rating scales measuring global cognitive performance in PD to make recommendations regarding their use. METHODS: A systematic literature search was conducted to identify the scales used to assess global cognitive performance in PD, and the identified scales were reviewed and rated as "recommended," "recommended with caveats," "suggested," or "listed" by the panel using previously established criteria. RESULTS: A total of 12 cognitive scales were included in this review. Three scales, the Montreal Cognitive Assessment, the Mattis Dementia Rating Scale Second Edition, and the Parkinson's Disease Cognitive Rating Scale, were classified as "recommended." Two scales were classified as "recommended with caveats": the Mini-Mental Parkinson, because of limited coverage of executive abilities, and the Scales for Outcomes in Parkinson's Disease-Cognition, which has limited data on sensitivity to change. Six other scales were classified as "suggested" and 1 scale as "listed." CONCLUSIONS: Because of the existence of "recommended" scales for assessment of global cognitive performance in PD, this task force suggests that the development of a new scale for this purpose is not needed at this time. However, global cognitive scales are not a substitute for comprehensive neuropsychological testing. (c) 2017 International Parkinson and Movement Disorder Society. PMID- 29168900 TI - Naphthodithiophene-Based Nonfullerene Acceptor for High-Performance Organic Photovoltaics: Effect of Extended Conjugation. AB - Naphtho[1,2-b:5,6-b']dithiophene is extended to a fused octacyclic building block, which is end capped by strong electron-withdrawing 2-(5,6-difluoro-3-oxo 2,3-dihydro-1H-inden-1-ylidene)malononitrile to yield a fused-ring electron acceptor (IOIC2) for organic solar cells (OSCs). Relative to naphthalene-based IHIC2, naphthodithiophene-based IOIC2 with a larger pi-conjugation and a stronger electron-donating core shows a higher lowest unoccupied molecular orbital energy level (IOIC2: -3.78 eV vs IHIC2: -3.86 eV), broader absorption with a smaller optical bandgap (IOIC2: 1.55 eV vs IHIC2: 1.66 eV), and a higher electron mobility (IOIC2: 1.0 * 10-3 cm2 V-1 s-1 vs IHIC2: 5.0 * 10-4 cm2 V-1 s-1 ). Thus, IOIC2-based OSCs show higher values in open-circuit voltage, short-circuit current density, fill factor, and thereby much higher power conversion efficiency (PCE) values than those of the IHIC2-based counterpart. In particular, as-cast OSCs based on FTAZ: IOIC2 yield PCEs of up to 11.2%, higher than that of the control devices based on FTAZ: IHIC2 (7.45%). Furthermore, by using 0.2% 1,8 diiodooctane as the processing additive, a PCE of 12.3% is achieved from the FTAZ:IOIC2-based devices, higher than that of the FTAZ:IHIC2-based devices (7.31%). These results indicate that incorporating extended conjugation into the electron-donating fused-ring units in nonfullerene acceptors is a promising strategy for designing high-performance electron acceptors.

AB - Formaldehyde is a common indoor pollutant that is an irritant and has been classified as carcinogen to humans. Adsorption technology is safe and stable and removes formaldehyde efficiently, but its short life span and low adsorption capacity limit its indoor application. To overcome these limitations, we propose an in-situ thermally regenerated air purifier (TRAP) which self-regenerates as needed. This purifier has four working modes: cleaning mode, regeneration mode, exhaust mode, and outdoor air in-take mode, all of which are operated by valve switching. We developed a real-scale TRAP prototype with activated carbon as adsorbent. The experimental testing showed that the regeneration ratios for formaldehyde of TRAP were greater than 90% during 5 cycles of adsorption regeneration and that through the 5 cycles, there was no damage to the adsorption material as confirmed by scanning electron microscope (SEM) and Brunauer-Emmett Teller (BET) tests. The total energy consumption by the prototype for purifying 1000 m3 indoor air was 0.26 kWh. This in-situ thermal-regeneration method can recover the purifier's adsorption ability through at least five cycles. PMID- 29168903 TI - Black-Phosphorus-Based Orientation-Induced Diodes. AB - Despite many decades of research of diodes, which are fundamental components of electronic and photoelectronic devices with p-n or Schottky junctions using bulk or 2D materials, stereotyped architectures and complex technological processing (doping and multiple material operations) have limited future development. Here, a novel rectification device, an orientation-induced diode, assembled using only few-layered black phosphorus (BP) is investigated. The key to its realization is to utilize the remarkable anisotropy of BP in low dimensions and change the charge-transport conditions abruptly along the different crystal orientations. Rectification ratios of 6.8, 22, and 115 can be achieved in cruciform BP, cross stacked BP junctions, and BP junctions stacked with vertical orientations, respectively. The underlying physical processes and mechanisms can be explained using "orientation barrier" band theory. The theoretical results are experimentally confirmed using localized scanning photocurrent imaging. These orientation-induced optoelectronic devices open possibilities for 2D anisotropic materials with a new degree of freedom to improve modulation in diodes.

PMID- 29168904 TI - APOE, thought disorder, and SPARE-AD predict cognitive decline in established Parkinson's disease. AB - BACKGROUND: People with PD are at high risk of developing cognitive impairment and dementia. Cross-sectional studies have identified candidate biomarkers associated with cognitive decline. However, longitudinal studies on this topic are rarer, and few have investigated the use of biomarker panels encompassing multiple modalities. The objective of this study was to find baseline predictors of cognitive decline in longitudinally followed, nondemented Parkinson's disease patients. METHODS: We performed a prospective cohort study of 100 PD patients with a median disease duration of 6.4 years. All participants were nondemented at baseline. We examined 16 baseline biomarkers from clinical, genetic, biochemical, and MRI-based imaging modalities for their association with longitudinal cognitive decline for up to 8 years. We investigated biomarkers individually, as well as in a multivariate linear mixed-effects model encompassing multimodal biomarkers, with change in the Mattis Dementia Rating Scale-2 over time as the primary outcome. Annual consensus process-derived cognitive diagnosis was used for Cox proportional hazards modeling of risk for cognitive decline. RESULTS: In multivariate analysis, the presence of the APOE E4 allele, thought disorder, and an Alzheimer's disease pattern of brain atrophy (spatial pattern of abnormality for recognition of early Alzheimer's disease index) best predicted cognitive decline, with APOE E4 genotype exerting the greatest effect. The presence of the APOE E4 allele was associated with a 3.5 times higher risk of worsening cognitive diagnosis over time (HR, 3.53; 95% CI, 1.52-8.24; P < 0.05). The APOE genotype effect was not specific to any Mattis Dementia Rating Scale-2 domain.

AB - Photoregulation is among the most promising tools for development of dynamic DNA nanosystems, due to its high spatiotemporal precision, biocompatibility, and ease of use. So far, azobenzene and its derivatives have shown high potential in photocontrolling DNA duplex hybridization by light-dependent photoisomerization. Despite many recent advances, obtaining sufficiently high photoswitching efficiency under conditions more suitable for work with DNA nanostructures are challenging. Here we introduce a pair of arylazopyrazoles as new photoswitches for efficient and reversible control of DNA hybridization achieved even at room temperature with a low number of required modifications. Their photophysical properties in the native state and in DNA strands result in near-quantitative isomerization rates by irradiation with UV and orange light. To demonstrate the applicability of these photoswitches, we have successfully applied one of them to open and close a DNA hairpin by light at room temperature.

AB - In preceding studies the neotropical ascomycete Hypoxylon rickii turned out to be a prolific source of new secondary metabolites, considering that we had obtained terpenoids with five different scaffolds along with a series of terphenyls. From the mycelial extracts of a 70 L scale fermentation of this strain we additionally isolated nine new macrolides (1-9) by RP-HPLC. The planar structures were elucidated by NMR spectroscopy complemented by HR-ESIMS. The relative configurations were assigned by J-based configuration analyses and confirmed by Kishi's Universal Database. Subsequently, the absolute configurations were assigned by Mosher's method using the shift analysis of a tetra-MTPA derivative. For rickiol A (1) and E (5) we observed transesterification of 20-membered ring structures to 22-membered isomers rickiol A2 (6) and E2 (7), and to 24-membered isomers rickiol A3 (8) and rickiol E3 (9), respectively. Cytotoxic effects and moderate antibiotic activity against Gram-positive bacteria were observed for 1-8 and 1-6 and 8, respectively. The total synthesis of rickiol E3 (9) established easier access to these compounds.

AB - 1,3-Bis(mesityl)imidazolium tetraphenylborate (IMesH+ BPh4- ) can be synthesized in one step by anion metathesis between the corresponding imidazolium chloride and sodium tetraphenylborate. In the presence of 2-isopropylthioxanthone (sensitizer), an IMes N-heterocyclic carbene (NHC) ligand can be photogenerated under irradiation at 365 nm through coupled electron/proton transfer reactions. By combining this tandem NHC photogenerator system with metathesis inactive [RuCl2 (p-cymene)]2 precatalyst, the highly active RuCl2 (p-cymene)(IMes) complex can be formed in situ, enabling a complete ring-opening metathesis polymerization (ROMP) of norbornene in the matter of minutes at room temperature. To the best of our knowledge, this is the first example of a photogenerated NHC. Its exploitation in photoROMP has resulted in a simplified process compared to current photocatalysts, because only stable commercial or easily synthesized reagents are required. PMID- 29168910 TI - Parental Immunisation Needs and Attitudes Survey in paediatric hospital clinics and community maternal and child health centres in Melbourne, Australia. AB - AIM: Despite Australia's high vaccination rates, an estimated 3.3% of children are under-vaccinated due to vaccine refusal and the proportion of parents with concerns is unclear. Amongst Australian parents, we aimed to determine the prevalence of vaccine concerns, resources and health-care providers (HCPs) accessed and satisfaction with these resources in two different settings. We also aimed to identify relationships between the level of vaccine concern, socio economic status and vaccine uptake. METHODS: Parents of children under 5 years attending general paediatric clinics in a tertiary paediatric hospital (n = 301/398, 76%) and children under 19 months attending community maternal child health centres (n = 311/391, 81%) completed the survey. Vaccination status was obtained from the Australian Childhood Immunisation Register. RESULTS: Despite high support for vaccination (98%, confidence interval (CI) 97-99), 43% of parents reported vaccine concerns (CI 40-47) including the number of vaccines given in the first 2 years (25%, CI 22 to 29), vaccine ingredients (22%, CI 19 25), allergies (18%, CI 15-21), weakening of the immune system (17%, CI 14-20) and autism (11%, CI 8-13). HCPs were the most commonly accessed and trusted information source. In all, 23% of parents reported insufficient knowledge to make good vaccination decisions (CI 20-26). There was little evidence of an association between parental vaccine acceptance or socio-economic status and vaccination status. CONCLUSIONS: Despite high support for vaccines, nearly half of Australian parents have some concerns and a quarter lack vaccine decision making confidence regarding childhood vaccines. Parents frequently access and report high trust in HCPs, who are best placed to address parental vaccine concerns through provision of clear information, using effective communication strategies. Further research in more highly hesitant populations is required to determine the relationship between the level and nature of vaccination concerns and vaccine uptake. PMID- 29168911 TI - Pre-operative parameters do not reliably identify post-operative respiratory risk in children undergoing adenotonsillectomy. AB - AIM: Adenotonsillectomy is performed in children with recurrent tonsillitis or obstructive sleep apnoea. Children at risk of post-operative respiratory complications are recommended to be monitored in paediatric intensive care unit (PICU). The aim of the study is to review the risk factors for post-operative complications and admissions to PICU. METHODS: A review of medical records of children who underwent adenotonsillectomy between January 2011 and December 2014 was performed. Association between demographic variables and post-operative complications were examined using chi-square and Mann-Whitney tests. RESULTS: A total of 214 children were identified, and of these, 19 (8.8%) experienced post operative complications. Six children (2.8%) had respiratory complications: hypoxaemia in four and laryngospasm requiring reintubation in a further two. Both of the latter patients were extubated upon arrival to PICU and required no escalation of therapy. A total of 13 (6.1%) children had non-respiratory complications: 8 (3.7%) had infection and 5 (2.3%) had haemorrhage. A total of 26 (12.1%) children were electively admitted to PICU and mean stay was 19.5 (SD +/- 13) h. No association between demographic characteristics, comorbid conditions or polysomnographic parameters and post-operative complications were noted. A total of 194 (90.7%) children stayed only one night in hospital (median 1 day, range 1 5 days). CONCLUSION: The previously identified risk factors and criteria for PICU admission need revision, and new recommendations are necessary.

AB - Transition-metal oxides are one of the most promising anode materials for energy storage in lithium- and sodium-ion batteries (LIBs and NIBs, respectively). To improve the electrochemical performance of metal oxides (e.g., Co3 O4 ), such as capacity and cyclability, a convenient strategy (with a metal-organic framework as a template) is introduced to generate Zn- or Ni-doped Co3 O4 . The obtained hollow core-shell nanosized Co3 O4 (denoted as Zn/Ni-Co-Oxide) derived from pyrolyzing zinc or nickel co-doped ZIF-67 (Co(mIm)2 ; mIm=methylimidazole) shows a drastically enhanced capacity of 1300 mAh g-1 at a high current density of 5000 mA g-1 , compared with that of pristine cobalt oxide (800 mAh g-1 ) in LIBs. A zinc-doped Zn-Co-Oxide demonstrates a stable capacity of 1600 mAh g-1 at 1000 mA g-1 for 700 cycles and an excellent performance in full coin cells (cycled with LiNi0.5 Co0.3 Mn0.2 O2 ). Moreover, NIB tests show a stable capacity of 300 mAh g 1 for more than 250 cycles. PMID- 29168913 TI - Synthesis, characterization, and biological properties of composites of hydroxyapatite and hexagonal boron nitride. AB - Hydroxyapatite (HA), obtained from bovine bones, was successfully reinforced with hexagonal boron nitrite (h-BN). h-BN/HA composites, with BN content up to 1.5 wt %, were sintered at various temperatures between 1000 and 1300 degrees C, in air. Well-sintered samples were obtained after sintering at 1200 and 1300 degrees C. The presence of h-BN contributed to dense, fine, and well-crystallized microstructure. The results of X-ray diffraction analysis and FT-IR spectroscopy showed that the produced composites comprised biphasic beta-TCP/HCA (HCA: carbonate partially substituted HA). High values of mechanical properties were achieved, namely compression strength 155 MPa for the sample 0.5% h-BN/HA and Vickers microhardness of 716 HV for the samples 1.5% h-BN/HA, both sintered at 1300 degrees C. U2OS human bone osteosarcoma proliferation and cell viability showed no adverse effect in the presence of h-BN/HA, suggesting the potential use of the produced materials as safe biomaterials in bone tissue engineering.

AB - Unprecedented scatter plots of calculated versus measured NMR 2,3 JCH coupling constants in six densely oxygen functionalized epoxides are found with some B3LYP protocols, an effect attributed to stereoelectronic effects. Hence, 26 other exchange-correlation density functionals (xc DFs) are benchmarked in this work. Very good results are achieved with mPW1PW91 and PBE0 in conjunction with the pcJ 1 basis set (BS) of moderate size. A thorough statistical analysis of 53 relationships between the predicted and observed 2,3 JCH datasets is presented. The effects of some xc DFs, including their x and c parts, and BSs on the calculation results are discussed, also in the context of DFT modeling of electron-density distributions. Moreover, related 1 JCH datasets predicted with 11 different DF methods are considered and compared with the experimental data. Finally, some proposals for further improvement of existing DFs based on the available n JCH (n=1-3) values are briefly outlined, in line with recent results on the DFT electron densities. PMID- 29168915 TI - A Novel Microdevice for Rapid Neutrophil Purification and Phenotyping in Type 2 Diabetes Mellitus. AB - Neutrophil dysfunction is strongly linked to type 2 diabetes mellitus (T2DM) pathophysiology, but the prognostic potential of neutrophil biomarkers remains largely unexplored due to arduous leukocyte isolation methods. Herein, a novel integrated microdevice is reported for single-step neutrophil sorting and phenotyping (chemotaxis and formation of neutrophil extracellular traps (NETosis)) using small blood volumes (fingerprick). Untouched neutrophils are purified on-chip from whole blood directly using biomimetic cell margination and affinity-based capture, and are exposed to preloaded chemoattractant or NETosis stimulant to initiate chemotaxis or NETosis, respectively. Device performance is first characterized using healthy and in vitro inflamed blood samples (tumor necrosis factor alpha, high glucose), followed by clinical risk stratification in a cohort of subjects with T2DM. Interestingly, "high-risk" T2DM patients characterized by severe chemotaxis impairment reveal significantly higher C reactive protein levels and poor lipid metabolism characteristics as compared to "low-risk" subjects, and their neutrophil chemotaxis responses can be mitigated after in vitro metformin treatment. Overall, this unique and user-friendly microfluidics immune health profiling strategy can significantly aid the quantification of chemotaxis and NETosis in clinical settings, and be further translated into a tool for risk stratification and precision medicine methods in subjects with metabolic diseases such as T2DM. PMID- 29168916 TI - Fabrication, characterization, and biocompatibility assessment of a novel elastomeric nanofibrous scaffold: A potential scaffold for soft tissue engineering. AB - With regard to flexibility and strength properties requirements of soft biological tissue, elastomeric materials could be more beneficial in soft tissue engineering applications. The present work investigates the use of an elastic polymer, (polycaprolactone fumarate [PCLF]), for fabricating an electrospun scaffold. PCLF with number-average molecular weight of 13,284 g/mol was synthetized, electrospun PCLF:polycaprolactone (PCL) (70:30) nanofibrous scaffolds were fabricated and a novel strategy (in situ photo-crosslinking along with wet electrospinning) was applied for crosslinking of PCLF in the structure of PCLF:PCL nanofibers was presented. Sol fraction results, Fourier-transform infrared spectroscopy, and mechanical tests confirmed occurrence of crosslinking reaction. Strain at break and Young's modulus of crosslinked PCLF:PCL nanofibers fabricated was found to be 114.5 +/- 3.9% and 0.6 +/- 0.1 MPa, respectively, and dynamic mechanical analysis results revealed elasticity of nanofibers. MTS assay showed biocompatibility of PCLF:PCL (70:30) nanofibrous scaffolds. Our overall results showed that electrospun PCLF:PCL nanofibrous scaffold could be considered as a candidate for further in vitro and in vivo experiments and its application for engineering of soft tissues subjected to in vivo cyclic mechanical stresses.

PMID- 29168917 TI - In Vivo MR Imaging of Glioma Recruitment of Adoptive T-Cells Labeled with NaGdF4 TAT Nanoprobes. AB - Adoptive T lymphocyte immunotherapy is one of the most promising methods to treat residual lesions after glioma surgery. However, the fate of the adoptively transferred T-cells in vivo is unclear, hampering the understanding of this emerging therapy. Thus, it is highly desirable to develop noninvasive and quantitative in vivo tracking of these T-cells to glioma for better identification of the migratory fate and to provide objective evaluation of outcomes of adoptive T-cell immunotherapy targeting glioma. In this work, ultrasmall T1 MR-based nanoprobes, NaGdF4 -TAT, as molecular probes with high longitudinal relaxivity (8.93 mm-1 s-1 ) are designed. By means of HIV-1 transactivator (TAT) peptides, nearly 95% of the adoptive T-cells are labeled with the NaGdF4 -TAT nanoprobes without any measurable side effects on the labeled T-cells, which is remarkably superior to that of the control fluorescein isothiocyanate-NaGdF4 concerning labeling efficacy. Labeled adoptive T-cell clusters can be sensitively tracked in an orthotopic GL261-glioma model 24 h after intravenous infusion of 107 labeled T-cells by T1 -weighted MR imaging. Both in vitro and in vivo experiments show that the NaGdF4 -TAT nanoprobes labeling of T-cells may be a promising method to track adoptive T-cells to improve our understanding of the pathophysiology in adoptive immunotherapy for gliomas. PMID- 29168918 TI - Nano-Biohybrids: In Vivo Synthesis of Metal-Organic Frameworks inside Living Plants. AB - Plants have a complex passive fluid transport system capable of internalizing small molecules from the environment, and this system offers an ideal route for augmenting plants with functional nanomaterials. Current plant augmentation techniques use pre-formed nanomaterials and permeabilizing agents or plant cuttings. A so far unexplored concept is the formation of the functional material, in situ, from precursors small enough to be passively internalized through the roots without harming the plants. Metal-organic frameworks are ideal for in situ synthesis as they are composed of metal ions coordinated with organic ligands and have recently been mineralized around single-celled organisms in mild aqueous conditions. Herein, the synthesis of two types of metal-organic frameworks, zinc(2-methylimidazole)2 and lanthanide2 (terephthalate)3 , are reported inside a variety of plants. In situ synchrotron experiments help elucidate the formation kinetics and crystal phases of the nano-biohybrid plants. Plants augmented with luminescent metal-organic frameworks are utilized for small molecule sensing, although other applications, such as pathogen sensing, proton conductive plants, improved CO2 capture, bacteria-free nitrogen fixation, drought and fungi-resistance, and enhanced photosynthesis and photocatalysis, are foreseeable. Overall, the generation of functional materials inside of fully intact plants could lead to more complex nano-biohybrid sensors and organisms augmented with superior performance characteristics. PMID- 29168919 TI - Comparison of Complexation-Induced pKa Shifts in the Ground and Excited States of Dyes as Well as Different Macrocyclic Hosts and Their Manifestation in Host Retarded Excited-Dye Deprotonation. AB - 1-Aminopyrene and 1-naphthylamine-5-sulfonic acid were converted to the putrescine (1,4-diaminobutane)-substituted derivatives (dyes 1 and 2). The diaminobutyl anchor serves as a common binding motive for cation-receptor macrocycles such as cucurbit[n]urils (n = 6-8) and p-sulfonatocalix[4]arene. When protonated, they are prone to undergo a rapid deprotonation in their excited state to result in fluorescence from the unprotonated form (Forster cycle). The deprotonation can be suppressed by complexation with cation-receptor macrocycles, which allows the fluorescence of the locally excited (protonated) state to be dramatically enhanced (factor 12 for dye 1 and 83 for dye 2). This host-retarded excited-dye deprotonation is a direct consequence of the previously established complexation-induced pKa shifts that dyes undergo upon binding to a macrocyclic host. The data set also allows a systematic comparison of complexation-induced pKa shifts in the ground and excited state of a dye. The trends are comparable, which suggests that structural factors, that is, the geometry of the host-guest complexes, determine the magnitude of the shifts. In regard to the magnitude of the absolute pKa shifts on the size of the macrocycles, we observe for dye 2 that the complexation-induced pKa shifts decrease as the portals become larger along the cucurbit[n]uril series. PMID- 29168920 TI - A case report of open craniofacial sutures, a novel feature of systemic sclerosis? AB - Scleroderma is an uncommon connective-tissue disease, its key feature being excessive collagen deposition resulting in fibrosis of the skin and internal organs. There are different types that can vary in severity from localized scleroderma to systemic sclerosis. Various clinical and radiographic findings can be attributed to the disease, which arise owing to the progressive nature of microvascular changes and collagen deposition. These include limited mouth opening, xerostomia, periodontal disease and cardiac and pulmonary disease. Whilst bone resorption has been reported, as far as we are aware, the literature has not described a case with failure of bony suture closure. Hence, we would like to describe what is probably a unique case of a patient with a 5-year history of systemic sclerosis, who was referred for management of increased mobility of her upper central incisors. Radiographic imaging (conventional and three-dimensional) confirmed increased bone resorption, partly owing to periodontal disease, but also owing to an open premaxillary suture. Similarly, other craniofacial sutures were diagnosed as being open, and, to our knowledge, this represents a yet undescribed finding in a patient suffering from scleroderma.

AB - INTRODUCTION: Diabetes Mellitus has been considered an epidemic by the World Health Organization, with a high risk of morbidity and mortality. The treatment of this pathology consists in glycemic control, which can be done by oral hypoglycemic agents, insulin therapy, dietary guidance, regular physical activity, and psychosocial support. In addition, other adjuvant treatments are employed, such as phytotherapic, and one of the most used plants is Bauhinia forficata. Areas covered: In the current review, patents using Bauhinia forficata for the Diabetes Mellitus treatment have been analyzed. There were 03 patents in WIPO, 01 in Espacenet, 01 in USPTO, and 02 in INPI. Expert opinion: Patents on the adjuvant treatment of Diabetes Mellitus by Bauhinia forficata are discussed. Although there are some phytotherapy products containing this medicinal plant which has hypoglycemic effect here is still a need for the development of more products based on natural resources, for the treatment of this pathology, without side effects and with other benefits, to assist in the glycemia control in diabetic patients, and to improve their quality of life.

AB - Various kinds of image-guided techniques have been successfully applied in the last years for the treatment of tumours, as alternative to surgical resection. High intensity focused ultrasound (HIFU) is a novel, totally non-invasive, image guided technique that allows for achieving tissue destruction with the application of focused ultrasound at high intensity. This technique has been successfully applied for the treatment of a large variety of diseases, including oncological and non-oncological diseases. One of the most fascinating aspects of image-guided ablations, and particularly of HIFU, is the reported possibility of determining a sort of stimulation of the immune system, with an unexpected "systemic" response to treatments designed to be "local". In the present article the mechanisms of action of HIFU are described, and the main clinical applications of this technique are reported, with a particular focus on the immune-stimulation process that might originate from tumour ablations. PMID- 29168925 TI - Enhanced degradation of 1-naphthol in landfill leachate using Arthrobacter sp. AB - Arthrobacter sp. named as JY5-1 isolated from contaminated soil of a coking plant can degrade 1-naphthol as the sole carbon source. Through identification of species, analysis of the optimal degradation condition and kinetic equation, the degradation characteristic of Arthrobacter sp. JY5-1 was obtained. Later, the acclimated strain was added into the bio-reactor to observe treatment performance of landfill leachate. The results showed that the optimal conditions for strain JY5-1 biodegradation in the study were pH 7.0 and 30oC. The bio-reactor operation experiment declared that Arthrobacter sp. JY5-1 had a strengthened effect on COD removal of landfill leachate. Moreover, the efficiency of COD removal could be high and stable when JY5-1 was accumulated as a biofilm together with active sludge. These results demonstrate that adding 1-naphthol-degrading strain JY5-1 is a feasible technique for the enhanced treatment of sanitary landfill leachate, providing theoretical support for engineering utilization. PMID- 29168923 TI - Calpain-2 as a therapeutic target for acute neuronal injury. AB - INTRODUCTION: Calpains represent a family of neutral, calcium-dependent proteases, which modify the function of their target proteins by partial truncation. These proteases have been implicated in numerous cell functions, including cell division, proliferation, migration, and death. In the CNS, where calpain-1 and calpain-2 are the main calpain isoforms, their activation has been linked to synaptic plasticity as well as to neurodegeneration. This review will focus on the role of calpain-2 in acute neuronal injury and discuss the possibility of developing selective calpain-2 inhibitors for therapeutic purposes. Areas covered: This review covers the literature showing how calpain-2 is implicated in neuronal death in a number of pathological conditions. The possibility of developing new selective calpain-2 inhibitors for treating these conditions is discussed. Expert opinion: As evidence accumulates that calpain-2 activation participates in acute neuronal injury, there is interest in developing therapeutic approaches using selective calpain-2 inhibitors. Recent data indicate the potential use of such inhibitors in various pathologies associated with acute neuronal death. The possibility of extending the use of such inhibitors to more chronic forms of neurodegeneration is discussed. PMID- 29168927 TI - Synergism of CuS and tartaric acid in the reduction of Cr(VI) under an irradiation of simulated solar light. AB - The synergism of CuS and tartaric acid (TA) in the reduction of Cr(VI) with an irradiation of simulated solar light was investigated through observing the effects of solution pH, temperature, CuS loading and TA concentration on the removal efficiency of Cr(VI). Approximately 32% and 54% of the initial Cr(VI) (100 umol/L) were reduced within 180 min by TA and CuS with light, respectively. Under the same condition, however, almost a complete removal of the initial Cr(VI) was achieved within 130 min in the coexistence of CuS and TA. In the case, it is considered that Cr(VI) was rapidly reduced in two main pathways. One is that H2S produced from the dissolution of CuS in weak acidic solution directly reduced Cr(VI) to Cr(III). The other is that Cu(II) released from CuS reacted with TA to form complexes with photochemical activity, producing Cu(I) through ligand-to-metal electron transfer, and then the reduction of Cr(VI) was coupled with a conversion of Cu(I) to Cu(II). Thus, a cycle catalytic system was established for the reduction of Cr(VI). Moreover, it is observed that the reaction could be divided into two stages: the initial chemical reduction of Cr(VI) by H2S and the later photochemical reduction of Cr(VI) by Cu(II)-TA complexes. PMID- 29168926 TI - Three-dimensional imaging of soft and hard facial tissues in patients with craniofacial syndromes: a systematic review of methodological quality. AB - OBJECTIVES: To systematically review the methodological quality of three dimensional imaging studies of patients with craniofacial syndromes and to propose recommendations for future research. METHODS: PubMed, Embase and Cochrane databases as well as Grey literature were electronically searched. Inclusion criteria were patients with genetic syndromes with craniofacial manifestations and three-dimensional imaging of facial soft and/or hard tissues. Exclusion criteria consisted of non-syndromic conditions or conditions owing to environmental causes, injury or trauma, facial soft and hard tissues not included in the image analysis, case reports, reviews, opinion articles. No restrictions were made for patients' ethnicity nor age, publication language or publication date. Study quality was evaluated using the Methodological Index for Non Randomized Studies (MINORS). RESULTS: The search yielded 2228 citations of which 116 were assessed in detail and 60 were eventually included in this review. Studies showed a large heterogeneity in study design, sample size and patient age. An increase was observed in the amount of studies with time, and the imaging method most often used was CT. The most studied craniofacial syndromes were Treacher Collins, Crouzon and Apert syndrome. The articles could be divided into three main groups: diagnostic studies (34/60, 57%), evaluation of surgical outcomes (21/60, 35%) and evaluation of imaging techniques (5/60, 8%). For comparative studies, the median MINORS score was 13 (12-15, 25-75th percentile), and for non-comparative studies, the median MINORS score was 8 (7-9, 25-75th percentile). CONCLUSIONS: The median MINORS scores were only 50 and 54% of the maximum scores and there was a lack of prospective, controlled trials with sufficiently large study groups. To improve the quality of future studies in this domain and given the low incidence of craniofacial syndromes, more prospective multicentre controlled trials should be set up. PMID- 29168928 TI - Regulation of Kv1.4 potassium channels by PKC and AMPK kinases. AB - Over the last years extensive kinase-mediated regulation of a number of voltage gated potassium (Kv) channels important in cardiac electrophysiology has been reported. This includes regulation of Kv1.5, Kv7.1 and Kv11.1 cell surface expression, where the kinase-mediated regulation appears to center around the ubiquitin ligase Nedd4-2. In the present study we examined whether Kv1.4, constituting the cardiac Ito,s current, is subject to similar regulation. In the epithelial Madin-Darby Canine Kidney (MDCK) cell line, which constitutes a highly reproducible model system for addressing membrane targeting, we find, by confocal microscopy, that Kv1.4 cell surface expression is downregulated by activation of protein kinase C (PKC) and AMP-activated protein kinase (AMPK). In contrast, manipulating the activities of phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K) and serum and glucocorticoid-regulated kinase 1 (SGK1) were without effect on channel localization. The PKC and AMPK-mediated downregulation of Kv1.4 membrane surface localization was confirmed by two-electrode voltage clamp in Xenopus laevis oocytes, where pharmacological activation of PKC and AMPK reduced Kv1.4 current levels. We further demonstrate that unlike related Kv channels, Kv1.4 current levels in Xenopus laevis oocytes are not reduced by co-expression of Nedd4-2, or the related Nedd4-1 ubiquitin ligase. In conclusion, we demonstrate that the surface expression of Kv1.4 is downregulated by the two kinases AMPK and PKC, but is unaffected by PI3K-SGK1 signaling, as well as Nedd4 1/Nedd4-2 activity. In the light of previous reports, our results demonstrate an impressive heterogeneity in the molecular pathways controlling the surface expression of highly related potassium channel subunits.

AB - This work aimed to investigate the potential effect of cyclodextrin encapsulation on intrinsic ability of daidzein (DAD) and genistein (GEN) to inhibit the glycosaminoglycan (GAG) synthesis in fibroblasts originating from patients with mucopolysaccharidosis (MPS), type II and III. DAD or GEN encapsulation with either 2-hydroxypropyl-beta-cyclodextrin or sulphobuthylether-beta-cyclodextrin were achieved by neat grinding and were characterised by thermal analysis, X-ray powder diffraction, scanning electron microscopy and solubility testing which confirmed the complexes formation with increased solubility with respect to starting compounds. Both isoflavones, as well as their co-ground cyclodextrin complexes reduced GAG levels in the fibroblasts of MPS II and MPS III patients from 54.8-77.5%, in a dose dependent manner, without any significant cytotoxic effect. Cyclodextrin encapsulation did not change the intrinsically high effect of both DAD and GEN on the GAG level reduction in the treated cells, thus could be considered as a part of combination therapies of MPS. PMID- 29168929 TI - Kinin B1 receptors as a therapeutic target for inflammation. AB - INTRODUCTION: Kinins are peptide mediators exerting their pro-inflammatory actions by the selective stimulation of two distinct G-protein coupled receptors, termed BKB1R and BKB2R. While BKB2R is constitutively expressed in a multitude of tissues, BKB1R is hardly expressed at baseline but highly inducible by inflammatory mediators. In particular, BKB1R was shown to be involved in the pathogenesis of numerous inflammatory diseases. Areas covered: This review intends to evaluate the therapeutic potential of substances interacting with the BKB1R. To this purpose we summarize the published literature on animal studies with antagonists and knockout mice for this receptor. Expert Opinion: In most cases the pharmacological inhibition of BKB1R or its genetic deletion was beneficial for the outcome of the disease in animal models. Therefore, several companies have developed BKB1R antagonists and tested them in phase I and II clinical trials. However, none of the developed BKB1R antagonists was further developed for clinical use. We discuss possible reasons for this failure of translation of preclinical findings on BKB1R antagonists into the clinic. PMID- 29168931 TI - Plasma concentrations of cytisine, a commercially available plant-based alkaloid, in healthy adult smokers taking recommended doses for smoking cessation. AB - 1. Cytisine is a plant alkaloid that is a partial agonist for the alpha4beta2 nAChRs and is used as an aid to smoking cessation. To date, there are no published data on cytisine concentrations in humans following multiple dosing. The aim of this study was to determine cytisine plasma concentrations after taking recommended doses for smoking cessation and to report on adverse effects. 2. Subjects (n=10) were instructed to follow the 25-day standard dosing regimen of cytisine. Blood was collected at 0, 2, 4, 8 and 10 hours on day 1 then on subsequent visits (days 2, 3, 4, 6, 13, 14, 17, 18, 21, 22, 25 and 26) to measure plasma cytisine concentrations. Plasma concentrations were determined using a validated LC-MS method. 3. Accumulation of cytisine was observed with repeated dosing of cytisine on day 1. Mean +/- SEM plasma cytisine concentration measured at 10 hours was 50.8 +/- 4.7 ng/mL. Due to dose tapering, there was an overall decrease in plasma cytisine concentration over the whole treatment period. 4. Overall, cytisine was well-tolerated and adverse effects reported were minor, indicating that cytisine is safe at concentrations measured in this study.

AB - Polyethylene (PE) plates grafted with a neutral monomer, 2-hydroxyethyl methacrylate (HEMA), and a cationic monomer, 2-(dimethylamino)ethyl methacrylate (DMAEMA), (PE-g-PHEMA)-g-PDMAEMA plates were prepared by the two-step photografting. The Cr(VI) ion adsorption behavior of the (PE-g-PHEMA)-g-PDMAEMA plates was investigated as a function of the amounts of grafted HEMA, amount of grafted DMAEMA, initial pH value, and temperature. The adsorption capacity of the DMAEMA-grafted PE (PE-g-PDMAEMA) and (PE-g-PHEMA)-g-PDMAEMA plates had the maximum value at the initial pH value of 3.0, independent of the temperature. The adsorption capacity of (PE-g-PHEMA)-g-PDMAEMA plates increased with the amount of grafted HEMA (GHEMA) in the first-step grafting. The increase in the water absorptivity of the grafted layers and thereby the increase in the degree of protonation of dimethylamino groups on grafted PDMAEMA chains were found to lead to the increase in the adsorption capacity. This adsorption capacity was higher than or comparable to those of other polymeric adsorbents for Cr(VI) ions. The Cr(VI) ion adsorption behavior on both PE-g-DMAEMA and (PE-g-PHEMA)-g-PDMAEMA plates obeyed the mechanism of the pseudo-second-order kinetic model and was well expressed by Langmuir isotherm. The high values of the Langmuir constant suggest that the adsorption of Cr(VI) ions occurs through an electrostatic interaction between protonated dimethylamino groups on grafted PDMAEMA chains and [Formula: see text]ions. Cr(VI) ions were successfully desorbed from PE-g-PDMAEMA and (PE-g PHEMA)-g-PDMAEMA plates in eluents such as NaCl, NaCl containing NaOH, NH4Cl, NH4Cl containing NaOH, and NaOH.

AB - INTRODUCTION: Adjuvant platinum based chemotherapy is accepted as standard of care in stage II and III non-small cell lung cancer (NSCLC) patients and is often considered in patients with stage IB disease who have tumors >= 4 cm. The survival advantage is modest with approximately 5% at 5 years. Areas covered: This review article presents relevant data regarding chemotherapy use in the perioperative setting for early stage NSCLC. A literature search was performed utilizing PubMed as well as clinical trial.gov. Randomized phase III studies in this setting including adjuvant and neoadjuvant use of chemotherapy as well as ongoing trials on targeted therapy and immunotherapy are also discussed. Expert commentary: With increasing utilization of screening computed tomography scans, it is possible that the percentage of early stage NSCLC patients will increase in the coming years. Benefits of adjuvant chemotherapy in early stage NSCLC patients remain modest. There is a need to better define patients most likely to derive survival benefit from adjuvant therapy and spare patients who do not need adjuvant chemotherapy due to the toxicity of such therapy. Trials for adjuvant targeted therapy, including adjuvant EGFR-TKI trials and trials of immunotherapy drugs are ongoing and will define the role of these agents as adjuvant therapy.

AB - BACKGROUND: The current study tried to evaluate the factors affecting 10- to 20- years' survival among long term survivors (>5 years) of colorectal cancer (CRC). METHODS: Surveillance, Epidemiology and End Results (SEER) database (1988-2008) was queried through SEER*Stat program.Univariate probability of overall and cancer-specific survival was determined and the difference between groups was examined. Multivariate analysis for factors affecting overall and cancer-specific survival was also conducted. RESULTS: Among node positive patients (Dukes C), 34% of the deaths beyond 5 years can be attributed to CRC; while among M1 patients, 63% of the deaths beyond 5 years can be attributed to CRC. The following factors were predictors of better overall survival in multivariate analysis: younger age, white race (versus black race), female gender, Right colon location (versus rectal location), earlier stage and surgery (P <0.0001 for all parameters). Similarly, the following factors were predictors of better cancer-specific survival in multivariate analysis: younger age, white race (versus black race), female gender, Right colon location (versus left colon and rectal locations), earlier stage and surgery (P <0.0001 for all parameters). CONCLUSION: Among node positive long-term CRC survivors, more than one third of all deaths can be attributed to CRC. PMID- 29168935 TI - Epithelial plasticity and metastatic cascade. PMID- 29168937 TI - Managing the nutritional needs of palliative care patients. AB - The nutritional needs of patients receiving palliative care should be routinely assessed, taking into account disease trajectory and nutrition-related symptoms. The social and emotional aspects of eating and drinking should also be acknowledged; as should the distress that weight loss and anorexia engenders in patients and their families. Practical strategies to optimise nutritional intake are discussed. Open and sensitive communication of patients' needs and wishes is essential, especially when discussing complementary nutrition approaches. A holistic, multidisciplinary approach is key to meeting nutritional needs, and the goals of nutritional intervention should be regularly reviewed in the light of disease progression. PMID- 29168936 TI - Does CBCT alter the diagnostic thinking efficacy, management and prognosis of patients with suspected Stage 0 medication-related osteonecrosis of the jaws? AB - OBJECTIVES: To evaluate the impact of cone beam CT (CBCT) in the diagnostic thinking efficacy, management and prognosis of patients with suspected Stage 0 medication-related osteonecrosis of the jaw (MRONJ). METHODS: For 15 patients with suspected Stage 0 MRONJ, clinical photographs, a panoramic radiograph and selected CBCT sections were identified. 13 oral surgeons reviewed the material and answered 10 questions in two different sessions. First session included clinical photographs and panoramic radiographs, while second session also included CBCT images. Questions (Qs) referred to dental disease and bone abnormalities (Qs 1, 2 and 3), differential diagnosis (Qs 4 and 5), patient management (Qs 6 and 7) and prognosis (Qs 8 and 9). Q 10 queried indication (first session) and usefulness (second session) of CBCT images. RESULTS: Qs 2, 3, 5, 7 and 9 scores increased between sessions, with statistical differences for Qs 2, 3, 5 and 7 (<0.05). Patients 2, 8 and 11 showed a significant increase in the average score of all Qs between sessions, while scores for patient 10 nearly reached statistical significance (p = 0.055). For Q 10, 57.4% of answers reported that CBCT was needed (first session) and was beneficial (second session). CONCLUSIONS: CBCT had a significant impact in differential diagnosis and management of patients with suspected Stage 0 MRONJ. PMID- 29168938 TI - High-dependency care: experiences of the psychosocial work environment. AB - AIM: to explore high-dependency care nurses' experiences of their psychosocial work environment. METHODS: four focus groups were conducted with 23 emergency and critical care hospital nurses in Brunei. All sessions were recorded, transcribed verbatim and analysed using inductive-approach thematic analysis. FINDINGS: three major themes were identified. 'Specialisation/specific skills' explained a fundamental requirement for the high-dependency care nurses to work effectively and efficiently in their workplace. 'Task completion' narrated the pressure they experienced to complete their tasks within time constraints exacerbated by a reduced number of staff. 'Acknowledgement' signified their need for fair and adequate reward for their hard work through career progression and promotion. CONCLUSION: this study facilitates the design of future interventions and policies that promote a healthy psychosocial work environment by ensuring nurses working in these areas have the required specialisation skills, there is a balance of workload and nurse-to-patient ratios, and they are offered fairness and equity in career progression and promotion.

AB - Nursing education is continuously evolving to meet Nursing and Midwifery Council (NMC) requirements for registered nurses. NMC standards state that all registered nurses are responsible for the student learning experience. However, newly qualified nurses can feel underprepared to support pre-registration student learning in the clinical area as the university setting does not facilitate formal peer support. This article will discuss the implementation of a peer facilitation scheme for pre-registration nursing students undertaking the BSc (Hons) and PGDip programmes in a higher education institution in London. The scheme trained second-year nursing students to be peer facilitators for first year clinical skills sessions. This article will also consider the benefits of the scheme for both first and second-year student nurses. PMID- 29168941 TI - Causes, assessment and management of fatigue in critically ill patients. AB - Fatigue is a common complaint among hospitalised patients and is one of the most prevalent and distressing symptoms reported by critically ill patients in the intensive care unit (ICU). Fatigue comes in many forms, is associated with a wide range of aetiologies, and is aggravated and intensified by a multitude of environmental and situational factors present in the intensive care environment. While assessing and evaluating fatigue is key to the effective management of this distressing symptom, reports have shown that fatigue assessment in the ICU is suboptimal and patients are often left suffering from its untoward consequences. Furthermore, the experience of fatigue that originates in the initial ICU admission often persists months to years after being discharged, and this has been shown to be associated with worse patient outcomes. Nurses are in an ideal position to identify, diagnose and evaluate patients who may be at risk of experiencing fatigue and put in place interventions as necessary. This article aims to discuss the incidence, causes, and clinical implications of fatigue among ICU patients and discuss ways in which nurses can effectively assess, diagnose, evaluate, manage and treat patient's fatigue within the ICU environment.

PMID- 29168945 TI - Analysis of the experiences of nurses who return to nursing after cancer. AB - BACKGROUND: understanding the impact of role ambiguity (both professional and patient) can be a factor in deepening the understanding of the ongoing personal, professional and organisational requirements of nurses who are cancer survivors. PURPOSE: the aim of this qualitative study was to elucidate an in-depth description of nurses' experiences of surviving cancer. METHOD: an exploratory qualitative research design was used (n=8), with participants recruited between September 2014 and December 2016. DISCUSSION: data analysis led to the emergence of six themes: being practical about the diagnosis and treatment, empathy and compassion, a 'new normal' and the role of organisational support, medical knowledge and treatment experiences, coping in silence and denial, and being resilient. CONCLUSION: nurses as cancer survivors who return to work offer a richness of experience related to enhanced empathetic responses to patients in their care and have the potential to be great practice role-models for other staff. PMID- 29168946 TI - Using an electronic assessment system for nursing students on placements. AB - Electronic assessment is gaining popularity in clinically based elements of pre registration nurse education. In this study, the authors explored student nurse and mentor experiences during transition from a paper to an electronic system. Mixed research methods used included survey questionnaires and focus groups. Student nurses and their mentors (both n=5) discussed and rated their confidence and skills in information technology and their experience of an electronic assessment document before and after two successive clinical placements. Students' self-reported confidence increased after both placements; mentors' confidence fell after the first placement. Students reported the fewest needs for additional support, while mentors expressed anxieties about system navigation and time required. The main barrier was lack of access to computers connected to the internet in the practice environment. Nevertheless, students and mentors were receptive to the change. Training and support was seen as essential. Serious challenges in up-scaling this system for complete student cohorts lie in wait if computer availability is not addressed.

AB - BACKGROUND: supporting the health and wellbeing of healthcare employees is a national priority in the UK. AIMS: to design, deliver and evaluate an educational package to promote health and wellbeing for nurses and midwives. METHODS: an online training package was developed and administered in two ways: online (HAWN online) or in a face-to-face workshop (HAWN-contact). A mixed methods evaluation was used to assess usability and acceptability of HAWN training. FINDINGS: 316 nurses, midwives and students completed the online training package and 16 participants attended the workshop. HAWN-online significantly increased knowledge in core areas of workplace health and wellbeing. Nurses and midwives valued online and face-to-face delivery but found there were barriers to attendance at workshops. Participants advocated that training in workplace health should be mandatory for all frontline staff. CONCLUSIONS: employers should take steps to promote staff wellbeing through HAWN training, and address barriers to accessing workplace health training or supportive services.

AB - Introduction Until now, the services provided to Iranian youth have been prepared based on authorities' perspectives and according to the resources and reports from other countries and international agencies. Using youth perspectives to provide health, however, helps in continuing the process of providing health services, and most young people will receive these services. Objective To explain perception of youth and key individuals to improve health programs for safe transition in Iran. Methodology This study is a qualitative research with a grounded theory approach. Data were collected using semi-structured in-depth interviews and group discussions. Participants were first selected by purposive sampling and then by theoretical sampling. Overall, 67 adolescents aged 14-18 years, eight youths aged 19-24 years, 12 parents and important persons involved in providing health services joined the study. Young participants and their parents were selected from different training areas of Tehran and the key individuals were from the Ministry of Health and Medical Education and the Education Department. Collecting samples were continued to saturation. The Strauss and Corbin (2008) method was used for data analysis. Result In this study, the phenomenon of adolescents' confusion to manage puberty emerged. This process, with appropriate strategies, such as the mobilization of available resources in the community and comprehensive programming to provide health services by policymakers, could have provided youth empowerment as an impact to self-care. Conclusion Current services provided by health centers cannot guarantee the health of adolescents, but it does require proper planning and management in families, schools and societies. PMID- 29168955 TI - Adherence to a Mediterranean dietary pattern and overweight and obesity among female adolescents in Iran. AB - Background Given the high prevalence of overweight and obesity in Iran, identification of a healthy diet is essential. Objective This study aimed to assess the association between adherence to a Mediterranean diet and overweight and obesity in female adolescents. Methods Two hundred and eighty female adolescents from high schools in Tehran were recruited. General information, physical activity and food frequency questionnaires were completed. Adherence to the Mediterranean diet was evaluated using the Mediterranean Style Dietary Pattern Score (MSDPS). Results Under and over reporters of energy intake were excluded from the analysis (n = 37). Results indicated that prevalence of overweight and obesity was 13.3% and 12.5%, respectively. The mean of MSDPS was low in this population (15.99 +/- 5.64). The MSDPS was positively associated with mother's education level and energy intake (p < 0.05). No significant relation was observed between MSDPS and overweight and obesity among adolescents. However, there was a negative significant association between MSDPS and WHR just among students who had educated mothers [high: second median v. low: first median, odds ratio (OR) = 0.36, 95% confidence interval (CI) = 0.12-1.03]. Conclusion Adherence to a Mediterranean dietary pattern is low among adolescent females in Tehran, with no association with overweight and obesity. PMID- 29168956 TI - (Health-related) quality of life and psychosocial factors in adolescents with chronic disease: a systematic literature review. AB - Background Research on living with a chronic disease (CD) in adolescence is increasing. However, studies on the relevance of psychosocial factors are still needed. The present review, focuses on the impact of living with a CD in adolescence on on quality of life (QoL), health-related quality of life (HRQoL) and psychosocial factors. Methods A literature review of articles identified through PubMed, PsycINFO and PsycARTICLES (these last two ones comprise the Ebsco Host platform) and original peer-reviewed research papers, published between 2010 and 2015, with no restrictions regarding the format/source of interventions, randomized controlled trials (RCTs) or types of comparisons were included. Results Eighteen papers met the inclusion criteria and contradictory results were found: the majority showed a significantly higher risk of impairment on QoL/HRQoL and psychosocial factors, whereas others reported a significantly lower risk of impairment (highlighting possible protective factors), or no significant differences. Heterogeneity in the assessment procedures and substantial difficulties in considering adolescence as a single and independent age group, were also noted. Conclusion The higher risk of impairment and the heterogeneity observed between cohorts, reinforce the need to work towards consensual procedures, which allow for more accurate comparisons among studies. Additionally, it conveys the challenge to find more effective interventions. Furthermore, it is highly suggested to routinely assess HRQoL/psychosocial factors within an individualized framework, to considerer adolescents as a single/independent group, to emphasize potential protective factors, and, to increase youth's participation in their own adaptation process and in health promotion in general. These are possible future directions that could enable multidisciplinary responses to improve HRQoL and psychosocial care in adolescents with a CD. PMID- 29168957 TI - The effects of introducing Tabata interval training and stability exercises to school children as a school-based intervention program. AB - Background Physical activities during leisure time as well as school hours have changed over the past few years, with adolescents being less physically active and adopting a sedentary lifestyle. Objective The overall objective of this mixed methods study was to evaluate the feasibility of introducing a 4-min Tabata interval training into a lower secondary school context. A further aim was to evaluate the possible effects on: coordination, balance, and strength. Methods The study was conducted as an intervention study with a mixed-method approach. Forty-three children, aged 7-9 years, participated in the intervention group. Additionally, 13 children were recruited as a control group. The intervention itself was delivered by the teachers and was performed for 4-min every day in a classroom setting. All participants performed physical tests before and after the intervention period to evaluate the Tabata training. After the completion of the 6-week Tabata interval training, the four teachers were interviewed. Results The push-ups (p = 0.004), kneeling push-ups (p = 0.03), and standing long jump (p = 0.01) improved in the intervention group after 6 weeks. No differences were observed between the genders. The teachers experienced that it worked well to integrate the Tabata interval training in the classroom setting. Conclusion After 6 weeks, a school-based Tabata intervention program improved physical performance. The teachers saw no obstacles in including the Tabata intervention program in a classroom setting and pointed out several positive aspects such as an increased energy level and development in the children's movement patterns. PMID- 29168958 TI - Relationships between physical activity, food choices, gender and BMI in Southern Californian teenagers. AB - Given the increased prevalence of pediatric obesity and risk of developing chronic disease, there has been great interest in preventing these conditions during childhood by focusing on healthy lifestyle habits, including nutritious eating and physical activity (PA). The purpose of this study was to determine the relationship between PA, body mass index (BMI) and food choices in adolescent males and females. This cross-sectional study, using a survey questionnaire, evaluated 1212 Southern Californian adolescents' self-reported PA, BMI and food frequency. Results revealed that even though males are more active than females, they have higher BMI percentile values (p < 0.05). Females consumed salad, vegetables and fruit more frequently than males (p < 0.05), where males consumed hamburgers, pizza, red meat, processed meat, eggs, fish, fruit juice, soda and whole milk more frequently than females (p < 0.05). Overweight/obese teens consumed red meat, processed meat and cheese more frequently than healthy weight teens (p < 0.05), yet there was no difference in PA between healthy and overweight/obese teens. These results demonstrate that higher levels of PA may not counteract an unhealthy diet. Even though PA provides numerous metabolic and health benefits, this study suggests that healthy food choices may have a protective effect against overweight and obesity. Healthy food choices, along with PA, should be advocated to improve adolescent health by encouraging maintenance of a healthy weight into adulthood. PMID- 29168959 TI - Effect of a brief training program for primigravid adolescents on parenting self efficacy and mother-infant bonding in the southeast of Iran. AB - Background Annually, about 16 million adolescent girls give birth, accounting for 11% of all births worldwide. Ninety-five percent of these births occur in low- and middle-income countries, and previous studies have addressed the need for parenting interventions in developing countries with limited health care resources to improve parenting behaviors. Objective To explore the effect of a brief training program for primigravid adolescents on parenting self-efficacy and mother-infant bonding. Subjects We enrolled 116 married pregnant adolescents. Methods This quasi-experimental study was conducted during August 22, 2016 February 3, 2017. The intervention group received three sessions of training on neonatal care, while the control group received the routine care. We evaluated parenting self-efficacy using the Perceived Maternal Parenting Self-Efficacy (PMP S-E) questionnaire, the mother-infant bonding using the Postpartum Bonding Questionnaire (PBQ) and social support by means of the Multidimensional Scale of Perceived Social Support (MSPSS). The participants were followed up for 1 month. Results The mean ages of the intervention and the control groups were 16.37 +/- 0.97 and 16.27 +/- 1.12 years, respectively. The intervention group obtained higher self-efficacy and bonding scores compared to the control group. The logistic regression model showed that the second (evoking behaviors) and the third (reading behavior or signaling) subscales of the PMP S-E, the route of delivery and women's educational levels could predict the mother-infant bonding scores. Conclusion Primigravid adolescents can benefit from brief interventions during pregnancy through improving their parenting self-efficacy and mother infant bonding. PMID- 29168960 TI - Using the Internet to access health-related information: results from a nationally representative sample of New Zealand secondary school students. AB - Objective To determine if secondary school students in New Zealand who report greater health concerns (e.g. significant depressive symptoms) are more likely to use the Internet to access health-related information. Methods A nationally representative health and wellbeing survey was undertaken in 2012 (n = 8500). Multiple regression models were used to examine the associations between students' use of the Internet to access health-related information and selected outcomes or indicators. Results Over 90% of students used the Internet on a daily basis, with 15.4% of students reporting that they had used the Internet to access health-related information. Students experiencing household poverty were more likely to report not using the Internet daily (17.4% compared to 4.2%). Odds ratios (ORs) for accessing the Internet for this sort of information were highest for students who reported self-harm [OR 2.7, 95% confidence interval (CI) 2.3 3.3], disordered eating (OR 2.7, 95% CI 2.4-3.2), or a suicide attempt (OR 2.5, 95% CI 1.9-3.3). Conclusion Our findings suggest that Internet-based health interventions may be a viable way to reach young people with high health needs, but consideration needs to be given to those with limited Internet access. PMID- 29168961 TI - Differences and similarities in medicine use, perceptions and sharing among adolescents in two different educational settings. AB - Background Evidence suggests that there are differences in medicine habits among adolescents with different sociodemographic backgrounds and that peers might also influence medicine use. More knowledge is needed regarding how these aspects together affect how different young people use medicines. Objective To explore the differences in medicine use, perceptions and sharing between adolescents at two different educational (and socio-demographic) settings and assess the influence of parents and peers. Subjects Fifty-nine students from a private high school (HS) and 34 students from a public vocational school (VS) in Denmark between the ages of 15 and 19 years old were subjects in this study. Methods A questionnaire was used that included background, medicine consumption, perceptions and social interaction. Descriptive analyses along with a Fishers test were used to determine differences and similarities between students' medicine patterns at the school settings. Results Of the 93 respondents, 74% used medicine within the past month, with females using more medicines. A significant difference was found with students at the VS using a higher number of medicines. Analgesics were the most frequently consumed medicine; however, reasons for using medicines appear to vary between the schools. Similarities between the schools were identified for perception of safety, sharing medicine and talking primarily with parents about medicine. Conclusion Fewer differences between students' medicine use at two educational settings than expected were identified, showing that aspects other than social background influence adolescents' use of medicine. A general tendency among young people believing that using medicines is a safe might explain these findings. PMID- 29168962 TI - Assessment of anxiety in adolescents involved in a study abroad program: a prospective study. AB - Objective The aim of the study was to measure the effects on levels of anxiety in healthy teenagers caused by a temporary change of country and school during a study abroad program. Methods In a prospective study we gathered the data from six anxiety level related tests on high school participants in a study abroad program (age 15-17, n = 364, M 172, F 192). These volunteer participants were divided into two separate groups: with self-reported elevated levels of anxiety (n = 111; YES-group) and with self-reported normal levels of anxiety (n = 253; NO group). Two control groups of schoolchildren drawn from two local schools were used for comparison (n = 100 each). Three tests were subjective, i.e. self-fill out tests. The next three tests were objective psychological or neurophysiological tests designed to estimate reflex control, concentration and a feeling for the passage of time. Results The initial mean anxiety level score among the 364 participants was 41.5 +/- 16.7 (min 16, max 80) on 5-110 scale. For the YES-group the score was 56.5 +/- 15.9, and for the NO-group the score was 34.7 +/- 17.4 (p = 0.05). The retesting after they had been in the same place for 7 weeks revealed that the mean anxiety level score of the participants decreased to 37.4 +/- 16.9 (min 15, max 72). For the YES-group the score significantly decreased to 39.3 +/- 15.5, and for the NO-group the score slightly elevated to 36.7 +/- 16.4 producing similar results for both groups (p = 0.81). Conclusion A temporary change of country and school at first results in a rise in anxiety levels in about one third of participants. However, after an extended stay it falls to normal levels. PMID- 29168963 TI - A comparison of positive youth development against depression and suicidal ideation in youth from Hong Kong and the Netherlands. AB - Background This study tests the buffering effects of positive youth development (PYD) factors against depression and suicidal ideation across Hong Kong and Dutch students. Methods We collected data on depression, suicidal ideation, history of childhood maltreatment, and PYD from 565 Dutch and Hong Kong undergraduates. The three PYD factors, prosocial attributes, positive identity, and cognitive behavioral competence, were examined for their moderating role in the relationship among childhood maltreatment, depression, and suicidal ideation in path analysis. Results Direct protective effects are found for all PYD factors in both cultures, except for cognitive-behavioral competence in the Dutch sample. A buffering effect of the PYD factors is observed in the maltreatment-depression relationship in Dutch, but not in Hong Kong students. Only behavioral competence buffers against suicidal ideation in Dutch students, while other PYD factors show no buffering effect in both groups of participants. Conclusion The differences in relationships between two samples highlights the need to consider cultural differences. PMID- 29168964 TI - Using theory of planned behavior for prediction of delivery mode among pregnant women: a theory-based cross-sectional research. AB - Background Nowadays, in Iran cesarean rates have increased from the recommended level of the World Health Organization (WHO). Objectives The objective of the present study was to determine which theory of planned behavior (TPB) constructs predict intentions and delivery mode among pregnant women. Methods One hundred and four pregnant nulliparous women in their third trimesters of pregnancy referred to Semirom health care centers were investigated based on census reports. The data were collected by valid and reliable questionnaire based on the TPB constructs and analyzed by SPSS16. Results In examining predictors using linear regression analysis to choose normal vaginal delivery (NVD), all constructs of TPB, including attitude toward NVD (p < 0.0001), subjective norms (p < 0.05) and perceived behavioral control (p < 0.001) were significantly correlated. Finally, after telephone follow-up with the women who had delivered newborns on their delivery method, it was found that 71.15% had a NVD and 28.14% had a cesarean delivery. Conclusions Regarding the effect of attitude to NVD, subjective norms and perceived behavioral control in NVD intention and its crucial role in anticipating the final delivery method, it is recommended considering these constructs in designing educational interventions for safe delivery in the investigated area. PMID- 29168965 TI - Relationships between metabolic profile, hypertension and uric acid with cardiometabolic risk in adolescents with abdominal obesity: impact of geodemographic factors on the prevalence of abdominal obesity. AB - Background Association of hyperuricemia, dyslipidemia and high blood pressure (BP) among adolescents with high waist-to-height ratio (WHtR) remains not fully addressed and could represent a new way to diagnose adolescents early with cardiometabolic risk. Objective We aimed to determine abdominal obesity (AO) prevalence and investigate relations between AO, uric acid (UA), lipid profiles, BP and geographical patterns in adolescents. Subjects 577 and 204 Algerian students aged between 10 and 19 years were included in our epidemiological and biochemical studies, respectively. Methods Height, weight, waist circumference (Wc) and hip circumferences, body mass index (BMI) and BP were measured. Fasting blood sampling was performed to measure glycemia, lipid profile, uricemia, insulinemia and leptinemia. The WHtR >=0.50 was applied for the diagnosis of AO and geodemographics was evaluated. Results The prevalence of AO was 12.13% among all students, 19.17% and 16.39% among students living in urban and plain areas, respectively. The risk of AO may be reduced in rural and mountainous areas. Lipid parameters, UA, insulin and leptin serum concentrations were significantly increased in adolescents with WHtR >=0.50 compared to those with WHtR <0.50. Cardiometabolic risk was increased with WHtR >=0.50 and BMI >26. Means of BMI, Wc, BP, and lipid parameters were significantly increased in the fourth quartiles compared to the first quartile of UA. Conclusion Urban areas and plains represent factors contributing to AO and WHtR >=0.50 may be used as a cut-off point to define risks of high BP, lipid abnormalities and UA serum level in Algerian adolescents. PMID- 29168966 TI - Increased risk of sadness and suicidality among victims of bullying experiencing additional threats to physical safety. AB - Objective To examine, in a nationally-representative sample of high school students, to what extent one or more additional threats to physical safety exacerbates the risk of sadness and suicidality among victims of school and/or cyber-bullying. Methods National data from the 2015 Youth Risk Behavior Survey (YRBS) were analyzed for grades 9-12 (n = 15,624). Victimization groups were characterized by school-bullying and cyber-bullying, with and without additional threats to physical safety: fighting at school, being threatened/injured at school, and skipping school out of fear for one's safety. Outcomes included 2 week sadness and suicidality. Outcomes for victimization groups were compared to non-victims using logistic regression adjusting for sex, grade and race/ethnicity. Results Overall, 20.2% of students were school-bullied, and 15.5% were cyber-bullied in the past year. Compared to non-victims, victims of school bullying and victims of cyber-bullying (VoCBs) who did not experience additional threats to physical safety were 2.76 and 3.83 times more likely to report 2-week sadness, and 3.39 and 3.27 times more likely to exhibit suicidality, respectively. Conversely, victims of bullying who experienced one or more additional threats to physical safety were successively more likely to report these adverse outcomes. Notably, victims of school-bullying and VoCBs with all three additional risk factors were 13.13 and 17.75 times more likely to exhibit suicidality, respectively. Conclusion Risk of depression symptoms and suicidality among victims of school-bullying and/or cyber-bullying is greatly increased among those who have experienced additional threats to physical safety: fighting at school, being threatened/injured at school and skipping school out of fear for their safety. PMID- 29168967 TI - Menstrual irregularity and use of oral contraceptives in female adolescent athletes in Swedish National Sports High Schools. AB - Objective Female adolescent athletes seem to use oral contraceptives (OCs) in the same proportion as the general population. In athletes not using OCs, menstrual irregularity (MI) is reported to be common but there are few studies of MI in adolescent athletes. The aim of the study was to survey menarche, menstrual irregularity and use of OCs in adolescent athletes in the National Sports High Schools in Sweden. A further aim was to study the associations between current sport injury and menstrual irregularity as well as use of OCs. Subjects Two hundred and ninety-eight female adolescent athletes at Swedish National Sports High Schools. Methods A web-based questionnaire containing questions related to menstrual status, contraception and current injury. Results One third (32.6%) of the athletes used OCs and of the remaining athletes 31.8% had MI. The group of athletes with MI had a significantly (p = 0.038; Cohen's d, 0.32) lower BMI and consisted of a significantly (p = 0.043) higher proportion of endurance athletes. OC users were less likely to participate in endurance sports compared to non-OC users (p = 0.024). Current injury was equally distributed in the OC and the non OC group but athletes with MI had fewer sports injuries compared to eumenorrheic women. Conclusion OCs are frequently used among athletes at Swedish National Sports High Schools. OC users were less likely to participate in endurance sports compared to non-OC users. MI was common and athletes with MI had lower BMI compared to eumenorrheic athletes. Sports injuries were not associated with use of OC and eumenorrheic athletes had a higher proportion of current injury. PMID- 29168968 TI - Cross-sectional comparison of age-related changes in the quadriceps femoris in Japanese basketball players. AB - Background This study examines age-related changes in the quadriceps femoris (QF), subdivided into the vastus medialis oblique (VMO), vastus medialis (VM), rectus femoris (RF), vastus intermedius (VI) and vastus lateralis (VL) in basketball players. Subjects Seventy male basketball players were divided into four groups according to age (12-13, 14-15, 16-17, and 18-20 years). Methods Ultrasonography was used to measure muscle architecture of the VMO, VM, RF, VI and VL. We created cubic approximate expressions and calculated inflexion points to evaluate peak growth age of each muscle head. Results Significant interactions were observed for all QF parts (p < 0.01-0.001). Muscle thickness (MT) in all QF parts was significantly lower in 12-13-year olds than in 18-20-year olds (p < 0.01-0.001). Significant differences were recognised between 12-13 and 16-17-year olds in VM (p < 0.001), RF (p < 0.001) and VL (p = 0.007). MT was significantly lower in 14-15-year olds than in 16-17-year olds in the VM (p = 0.007) and RF (p = 0.026) and in 18-20 year olds in the VM (p < 0.001), RF (p = 0.036) and VI (p < 0.001). Peak growth age was estimated for each QF part (VMO, 155.0 months; VM, 187.8 months; RF, 212.2 months, VI, 188.9 months; VL, 181.1 months). Conclusion QF parts have different growth rates due to differing functions in each muscle head. PMID- 29168969 TI - Comparing health promotion behaviors of male and female high school students in Southeast of Iran. AB - Background Adolescence is one of the most challenging periods of human life. Many healthy or risky behaviors may be formed during this period and continue to the end of life. The aim of this study was to examine and compare the health promotion behaviors of male and female students in high schools. Methods In this descriptive-comparative study, 609 high school students were selected using multi stage random sampling method. Data were collected using demographic and health promoting lifestyle profile (HPLPII) questionnaires. Results The mean of health promotion behaviors was moderate in female (2.43 +/- 0.46) and male (2.61 +/- 0.45) students. The highest and lowest means in the male students were respectively the dimensions of spiritual growth and health responsibility. Also, the highest and lowest means in the female students were dimensions of interpersonal relationships as well as physical activity and exercise. The status of male health promotion behaviors was significantly more favorable than that of the female (p = 0.001, t = -4.71). The male students had a better situation than female in terms of all the six dimensions of HPLPII, so there was a significant difference between them in the four dimensions of spiritual growth, stress management, physical activity and health responsibility. There was also a significant relationship between the history of physical and mental illness in the past year and the students' health promotion behaviors (p < 0.05). Conclusion The results indicated the importance of promoting self-care and educational interventions in the aspects such as physical activity and health responsibility of young people in order to improve the health of the community. PMID- 29168970 TI - Human adenovirus-36 seropositivity and obesity among Midwestern US adolescents. AB - Objective Human adenovirus-36 (Ad-36) infection has been implicated as a risk factor for obesity. This study aims to measure Ad-36 antibody prevalence among obese and healthy-weight Midwestern US adolescents. Methods Obese and healthy weight subjects 10-18 years of age attending an adolescent clinic in Missouri, USA, were tested for Ad-36 antibodies via ELISA assay. All subjects were measured for height and weight to determine body mass index (BMI). chi2 analysis was used to compare Ad-36 antibody prevalence between the two groups. Results Ad-36 antibodies were tested on 41 obese and 37 control subjects. The subjects' mean age at the time of sample collection was 15.6 years (SD 2.0). Ad-36 antibody prevalence was 43.9% among the obese group and 21.6% among the control group (p = 0.038). Discussion The findings show that statistically more obese Missouri adolescents test positive for Ad-36 antibodies than their healthy-weight peers, consistent with previous findings suggesting a correlation between Ad-36 infection and obesity. PMID- 29168971 TI - Self perceived psychosocial impact of dental aesthetics among young adults: a cross sectional questionnaire study. AB - Background Oral health is not merely the absence of oral disease and dysfunction, but also influences the subject's social life and dento-facial self confidence. Objective To assess and correlate self perceived psychosocial impact of dental aesthetics among young adults based on gender. Subjects A convenience sample of Young adults of degree college in the age group of 18-23 years of Hyderabad city, India. Method Self perceived psychosocial impact of dental aesthetics was assessed using the psychosocial impact of dental aesthetics questionnaire (PIDAQ). The dental aesthetic index (DAI) was used to evaluate dental aesthetics among participants which includes 10 parameters of dento-facial anomalies related to both clinical and aesthetic aspects of the anterior teeth. Results The majority of the study population were 18 years of age (96; 31.4%) with a mean age of 19.2 +/- 1.1 years. When the mean total score and individual domain scores of PIDAQ was compared based on gender, females showed higher statistical mean (p <= 0.05) for all except the psychology impact domain (p = 0.12). Based on DAI grading and gender, among both males [70 (32.9%)] and females [31 (33.3%)] the majority of them had a DAI score of <=25 (grade1; normal/minor dental malocclusion). A significant negative correlation was observed between DAI, with PIDAQ and its domains (p <= 0.05) except for the dental self confidence (p = 0.72). Conclusion This study had examined the relationship between self-perceived psychosocial impact and dental aesthetics. So, early preventive or interceptive procedures should be carried out to prevent further psychosocial impacts on human life. PMID- 29168972 TI - Experience of violence amongst female medical and nursing students and their perception regarding violence against women in Delhi, India. AB - Background Health care providers are often the first point of contact for the victims of violence against women (VAW). Therefore, it is important to understand their perception about VAW. Objective To assess the proportion of female medical students who experienced violence, and elicit their perception regarding the same. Methods It was a cross-sectional study undertaken among 50 medical and 50 nursing students of a medical college in Central Delhi. A self-administered, questionnaire was used for data collection. Results Of the total, 18% had experienced molestation while 77% had experienced eve-teasing during their lifetime. But, only 2% reported the incident to police. Perception regarding the victim's role and self-determination was favorable amongst the female students. However, only 39% knew some basic self-defense techniques. Conclusion The proportion of students who experienced eve-teasing in their lifetime was high. The study highlighted the need to make the female students more pro-active and competent in terms of tackling violence. PMID- 29168973 TI - Prevalence of obesity among youths in Mississippi: United States, 1999-2015. AB - Background The prevalence of obesity among youths has become a public health problem. The trend in the prevalence of obesity among high school students in Mississippi has not been examined in the last 17 years. Methods The data from the Mississippi High School Youth Risk Behavior Survey from 1999 to 2015 were used to determine the prevalence of obesity. The definition of obesity was based on age- and sex-specific body mass index (BMI) of more than 95th percentile, according to 2000 Centers for Disease Control and Prevention (CDC) growth charts. The differences in the groups were examined using the univariate t-test statistical analysis at p < 0.05 and frequency distribution to determine the percentage differences. Results There was a decline in the prevalence of obesity from 1999 to 2015 among Whites but no significant decrease among Blacks. The prevalence based on race in 2105 was 18.9%, which is higher than 14.4% in 1999 and remaining years. The rate of obesity based on race and sex was 27.7% among Blacks and 15.9% among White males in 2015. The Black females had prevalence of 20.6%, which is higher than their White counterpart (12.1%) in 2015 and previous years. Conclusion The prevalence of obesity among Blacks was higher when compared to White students. There was an increased prevalence of obesity in males over females. Students in 9th and 10th grade had a higher prevalence of obesity than those in 11th and 12th grade. PMID- 29168974 TI - HEEADSSS up: pediatric residents' confidence and practice in adolescent health care before and after mandatory adolescent medicine rotations in Thailand. AB - Background The field of adolescent medicine is an emerging area of specialization in Thailand. Adolescent medicine was made a mandatory rotation in general pediatric residency training programs for the class of 2013. Objective This study aims to explore the difference in pediatric residents' confidence and the frequency in providing aspects of care to adolescents. Subjects Participants included two groups of pediatric residents; the former curriculum group (FCG) in 2012 and the mandatory curriculum group (MCG) in 2015. Methods Participants in this cross-sectional study answered a 41-item self-administered questionnaire and results were analyzed by descriptive statistics. Results There were 91 participants, 50.05% were in the MCG. The FCG reported a higher percentage of feeling "more confident" on physical examination (p = 0.031, V = 0.23) and growth assessment (p = 0.040, V = 0.22). The MCG reported a higher percentage of "more frequently" carrying out the psychosocial assessment (p = 0.035, V = 0.22). Conclusion The FCG reported higher levels of confidence than the MCG in most of the items, while the MCG reported higher levels of frequency in providing care. The psychosocial (HEEADSSS) assessment, a key aspect of the adolescent clinical visit, was the item that the MCG reported doing more frequently than the FCG which remained significant when only the postgraduate year of training (PGY) 4s were compared. PMID- 29168975 TI - Treating malignant melanoma when a rare BRAF V600M mutation is present: case report and literature review. AB - Recent years have brought major advances in the treatment of malignant melanoma. One such an advance is the treatment with BRAF tyrosine-kinase inhibitors in metastatic malignant melanomas that harbor mutations in the BRAF gene. The trials that have been performed in this setting have demonstrated superior response rates and increased overall survival, however, they mostly included patients with melanomas carrying the more common V600E and V600K mutations, not being able to assess the benefit of these treatments in situations where more rare mutations of the BRAF gene are present. We present the evolution of a patient with malignant melanoma with a rare V600M mutation in the BRAF gene, that was eventually treated with vemurafenib. Also we present a brief review of the major phase III trials that showed benefit with tyrosine-kinase inhibitors in BRAF mutated melanoma, with respect to the BRAF mutations included.

AB - Psoriasis is a chronic, immune mediated disorder affecting approximately 2% of the population. Even in our days, patients with psoriasis are confronted with stigmatization and social rejection. As a result, their quality of life is significantly impaired. Biological therapies have revolutionized the treatment of moderate to severe psoriasis. The aim of this paper is to look over the most important biological therapies available for the management of plaque-type psoriasis. PMID- 29168978 TI - Excitations in the quantum liquid 4He: A review. AB - Progress made in measuring and interpreting the elementary excitations of superfluid and normal liquid [Formula: see text] in the past 25 years is reviewed. The goal is to bring up to date the data, calculations and our understanding of the excitations since the books and reviews of the early 1990s. Only bulk liquid [Formula: see text] is considered. Reference to liquid [Formula: see text], mixtures, reduced dimensions (films and confined helium) is made where useful to enhance interpretation. The focus is on the excitations as measured by inelastic neutron scattering methods. The review covers the dynamical response of liquid [Formula: see text] from the collective excitations at low energy and long wavelength (i.e. phonon-roton modes) to the single particle excitations at high energy from which the atomic momentum distribution and Bose-Einstein condensate fraction are determined. A goal is to show the interplay of these excitations with other spectacular properties such as superfluidity and the test of fundamental calculations of quantum liquids that is possible. The role of Bose Einstein condensation in determining the nature of the [Formula: see text] mode and particularly it's temperature dependence is emphasized. The similarity of normal liquid [Formula: see text] with other quantum and classical liquids is discussed. PMID- 29168979 TI - Prognostic Significance of Preoperative Neutrophil-to-Lymphocyte Ratio in Surgically Resectable Pancreatic Neuroendocrine Tumors. AB - BACKGROUND The aim of this study was to evaluate the predictive and prognostic value of the preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to lymphocyte ratio (PLR) in pancreatic neuroendocrine tumor (PNET) patients undergoing potentially curative resection. MATERIAL AND METHODS A retrospective review of 172 patients with PNETs was conducted. Kaplan-Meier curves and multivariate Cox proportional models were used to calculate overall survival (OS) and disease-free survival (DFS). The predictive performance of the NLR was compared with other inflammation-based scores and conventional stratification systems using receiver operating characteristic (ROC) curve analysis. RESULTS Elevated NLR and PLR were both associated with advanced AJCC stage and high grade. In the univariate analysis, elevated NLR and PLR were both significantly associated with decreased OS and DFS. In the multivariate analysis, the preoperative NLR, but not the PLR, was an independent risk factor for OS (HR=4.471, 95% CI 1.531-13.054, p=0.006) and DFS (HR=2.531, 95% CI 1.202-5.329, p=0.015). The discriminatory capability of the NLR was superior to that of other inflammation-based scores in OS prediction. Furthermore, the predictive range was expanded by incorporating the NLR into the conventional stratification systems, including the AJCC stage and WHO classification systems. CONCLUSIONS As an independent prognostic factor, an elevated preoperative NLR is superior to the PLR with respect to predicting clinical outcomes in PNET patients undergoing potentially curative resection. The incorporation of the NLR into the existing conventional stratification systems improved the predictive accuracy. PMID- 29168980 TI - Inability to reduce morbidity of diarrhea by ORS: can we design a better therapy? AB - Diarrheal disease is a worldwide problem that still causes significant morbidity and mortality among children. Currently, oral rehydration solution (ORS) is the standard of care for acute diarrhea in pediatric patients. Although effective in reducing mortality, ORS does not alleviate diarrheal symptoms, thus reducing caregiver compliance and therapeutic efficacy. This article will briefly review the current problem of pediatric diarrhea and the shortcomings of current therapies; however, the focus of this review is to examine the intestinal calcium sensing receptor (CaSR). The author summarizes the evidence suggesting that targeting the CaSR will enable clinicians to address all four major pathophysiological mechanisms of diarrheal disease, and substantiates the need for future research regarding this therapy. PMID- 29168981 TI - High-resolution rapid neonatal whole-body composition using 3.0 Tesla chemical shift magnetic resonance imaging. AB - BackgroundTo evaluate a whole-body rapid imaging technique to calculate neonatal lean body mass and percentage adiposity using 3.0 Tesla chemical shift magnetic resonance imaging (MRI).MethodsA 2-Point Dixon MRI technique was used to calculate whole-body fat and water images in term (n=10) and preterm (n=15) infants.ResultsChemical shift images were obtained in 42 s. MRI calculated whole body mass correlated closely with measured body weight (R2=0.87; P<0.001). Scan rescan analysis demonstrated a 95% limit of agreement of 1.3% adiposity. Preterm infants were born at a median of 25.7 weeks' gestation with birth weight 840 g. At term-corrected age, former preterm infants were lighter than term-born controls, 2,519 vs. 3,094 g regressing out age and group as covariates (P=0.005). However, this was not because of reduced percentage adiposity 26% vs. 24% (P=0.28). At term-corrected age, former preterm infants had significantly reduced lean body mass compared with that of term-born controls 1,935 vs. 2,416 g (P=0.002).ConclusionRapid whole-body imaging for assessment of lean body mass and adiposity in term and preterm infants is feasible, accurate, and repeatable. Deficits in whole-body mass in former preterm infants at term-corrected age are due to reductions in lean body mass not due to differences in adiposity. PMID- 29168983 TI - Reverse cascade screening for familial hypercholesterolemia in high-risk Chinese families. AB - BACKGROUND: Reverse cascade screening is not commonly employed to detect new cases of familial hypercholesterolemia (FH). We aimed to assess the outcome of this screening strategy in families in which the probands were children with severe FH. HYPOTHESIS: Reverse cascade screening is an effective method to detect new patients with FH. METHODS: Reverse cascade screening was undertaken starting from 47 index children with severe hypercholesterolemia; 39 were homozygous/compound heterozygous FH and 8 were heterozygous FH. Available parents, siblings, and second-degree relatives were contacted and screened. RESULTS: From the 39 cases of homozygous/compound heterozygous FH, 80 first degree family members were available for screening; 70 were parents and 10 were siblings. All first-degree relatives screened were genetically diagnosed with FH. None of the parents had been treated with statins at the time of diagnosis, and 10 (12.7%) had premature coronary artery disease. Additionally, 46 second-degree relatives were screened, of which 41 (89%) were diagnosed with FH. From the 8 heterozygous FH children, 17 first- and second-degree relatives were screened and 12 new cases of FH were also diagnosed. Hence, the overall diagnostic yield of screening was 2.8 new cases of FH per index case. CONCLUSIONS: Reverse cascade screening is a highly effective method for diagnosing new cases of FH in parents, siblings, and second-degree relatives of index children with severe FH. PMID- 29168984 TI - Transcatheter vs surgical aortic-valve replacement in low- to intermediate surgical-risk candidates: A meta-analysis and systematic review. AB - The American and European expert documents recommend transcatheter aortic valve replacement (TAVR) for inoperable or high-surgical-risk patients with severe aortic stenosis. In comparison, efficacy of TAVR is relatively less studied in low- to intermediate-surgical-risk patients. We sought to discover whether TAVR can be as effective as surgical aortic valve replacement (SAVR) in low- to intermediate-surgical-risk candidates. Four randomized clinical trials (RCTs) and 8 prospective matched studies were selected using PubMed/MEDLINE, Embase, and Cochrane Library (inception: March 2017). Results were reported as random-effects odds ratio (OR) with 95% confidence interval (CI). Among 9851 patients, analyses of RCTs showed that all-cause mortality was comparable between TAVR and SAVR (short term, OR: 1.19, 95% CI: 0.86-1.64, P = 0.30; mid-term, OR: 0.97, 95% CI: 0.75-1.26, P = 0.84; and long term, OR: 0.97, 95% CI: 0.81-1.16, P = 0.76). The analysis restricted to matched studies showed similar outcomes. In the analysis stratified by study design, no significant differences were noted in the RCTs for stroke, whereas TAVR was better than SAVR in matched studies at short term only (OR: 0.46, 95% CI: 0.33-0.65, P < 0.001). TAVR is associated with reduced risk of acute kidney injury and new-onset atrial fibrillation (P < 0.05). However, increased incidence of permanent pacemaker implantation and paravalvular leaks was observed with TAVR. TAVR can provide similar mortality outcome compared with SAVR in low- to intermediate-surgical-risk patients with critical aortic stenosis. However, both procedures are associated with their own array of adverse events. PMID- 29168985 TI - Association between diet quality and measures of body adiposity using the Rate Your Plate survey in patients presenting for coronary angiography. AB - BACKGROUND: Diet is a modifiable risk factor for cardiovascular disease; however, dietary patterns are historically difficult to capture in the clinical setting. Healthcare providers need assessment tools that can quickly summarize dietary patterns. Research should evaluate the effectiveness of these tools, such as Rate Your Plate (RYP), in the clinical setting. HYPOTHESIS: RYP diet quality scores are associated with measures of body adiposity in patients referred for coronary angiography. METHODS: Patients without a history of coronary revascularization (n = 400) were prospectively approached at a tertiary medical center in New York City prior to coronary angiography. Height, weight, and waist circumference (WC) were measured; body mass index (BMI) and waist-to-height ratio (WHtR) were calculated. Participants completed a 24-question RYP diet survey. An overall score was computed, and participants were divided into high (>=58) and low (<=57) diet quality groups. RESULTS: Participants in the high diet quality group (n = 98) had significantly lower measures of body adiposity than did those in the low diet quality group (n = 302): BMI (P < 0.001), WC (P = 0.001), WHtR (P = 0.001). There were small but significant inverse correlations between diet score and BMI, WC, and WHtR (P < 0.001). These associations remained significant after adjustment for demographics, tobacco use, and socioeconomic factors. CONCLUSIONS: Higher diet quality scores are associated with lower measures of body adiposity. RYP is a potential instrument to capture diet quality in a high-volume clinical setting. Further research should evaluate the utility of RYP in cardiovascular risk-factor control. PMID- 29168986 TI - Skin aging parameters: A window to heart block. AB - BACKGROUND: Skin acts as a mirror to the internal state of the body. HYPOTHESIS: We tried to find the relation between skin aging parameters and the incidence of degenerative AV block. METHODS: This study included 97 patients divided into 2 groups; group D comprised 49 patients with advanced-degree AV block, and group C comprised the 48 matched control group. All were subjected to full history taking, thorough clinical examination, calculation of intrinsic skin aging score, and resting 12-lead surface electrocardiography (ECG). ECG for all patients assessed left ventricular end-systolic diameter, left ventricular end-diastolic diameter, ejection fraction, left atrium (LA) diameter, aortic root diameter, mitral annular calcification, aortic sclerosis. Coronary angiography was also performed when indicated for patients in group D. RESULTS: Patients in group D had a higher percentages of uneven pigmentation, fine skin wrinkles, lax appearance, seborrheic keratosis, total score > 7 (38 [77.55%] vs 10 [20.83%]), mitral annular calcification score of 33 (67.34%) vs 5 (10.41%), aortic sclerosis score of 21 (42.85%) vs 4 (8.33%), and mean LA diameter of 39.98 +/- 5.52 vs 36.21 +/- 3 mm (P < 0.001). Total score > 6 is the best cutoff value to predict advanced-degree heart block with 89.79% sensitivity and 64.58% specificity. Seborrheic keratosis was the strongest independent predictor. CONCLUSIONS: Any population with a total intrinsic skin aging score of >6 is at high risk for developing advanced-degree AV block and should undergo periodic ECG follow-up for early detection of any conduction disturbance in the early asymptomatic stages to minimize sudden cardiac death. PMID- 29168982 TI - N-terminomics reveals control of Arabidopsis seed storage proteins and proteases by the Arg/N-end rule pathway. AB - The N-end rule pathway of targeted protein degradation is an important regulator of diverse processes in plants but detailed knowledge regarding its influence on the proteome is lacking. To investigate the impact of the Arg/N-end rule pathway on the proteome of etiolated seedlings, we used terminal amine isotopic labelling of substrates with tandem mass tags (TMT-TAILS) for relative quantification of N terminal peptides in prt6, an Arabidopsis thaliana N-end rule mutant lacking the E3 ligase PROTEOLYSIS6 (PRT6). TMT-TAILS identified over 4000 unique N-terminal peptides representing c. 2000 protein groups. Forty-five protein groups exhibited significantly increased N-terminal peptide abundance in prt6 seedlings, including cruciferins, major seed storage proteins, which were regulated by Group VII Ethylene Response Factor (ERFVII) transcription factors, known substrates of PRT6. Mobilisation of endosperm alpha-cruciferin was delayed in prt6 seedlings. N termini of several proteases were downregulated in prt6, including RD21A. RD21A transcript, protein and activity levels were downregulated in a largely ERFVII dependent manner. By contrast, cathepsin B3 protein and activity were upregulated by ERFVIIs independent of transcript. We propose that the PRT6 branch of the pathway regulates protease activities in a complex manner and optimises storage reserve mobilisation in the transition from seed to seedling via control of ERFVII action. PMID- 29168987 TI - Independent predictors of effective blood pressure control in patients with hypertension on drug treatment in Brazil. AB - Population assessment of effective blood pressure (BP) control is fundamental for reducing the global burden of hypertension, especially in low- and middle-income countries. The authors evaluated the effectiveness of BP control and determined independent predictors associated with effective control among patients with hypertension on drug treatment in a large cross-sectional study performed in two metropolitan areas in Brazil's southeast region. A total of 43 647 patients taking antihypertensive treatment were identified. Less than half of the patients (40.9%) had controlled BP (systolic BP <140 mm Hg and diastolic BP <90 mm Hg). Independent predictors of BP control were age, eating fruit daily, physical activity, previous cardiovascular disease, male sex, diabetes mellitus, ethnicity, and obesity. Simple variables associated with BP control may be utilized for knowledge translation strategies aiming to reduce the burden of hypertension. PMID- 29168988 TI - Characterizing Risk for Cumulative Risk Assessments. AB - In assessing environmental health risks, the risk characterization step synthesizes information gathered in evaluating exposures to stressors together with dose-response relationships, characteristics of the exposed population, and external environmental conditions. This article summarizes key steps of a cumulative risk assessment (CRA) followed by a discussion of considerations for characterizing cumulative risks. Cumulative risk characterizations differ considerably from single chemical- or single source-based risk characterization. CRAs typically focus on a specific population instead of a pollutant or pollutant source and should include an evaluation of all relevant sources contributing to the exposures in the population and other factors that influence dose-response relationships. Second, CRAs may include influential environmental and population specific conditions, involving multiple chemical and nonchemical stressors. Third, a CRA could examine multiple health effects, reflecting joint toxicity and the potential for toxicological interactions. Fourth, the complexities often necessitate simplifying methods, including judgment-based and semi-quantitative indices that collapse disparate data into numerical scores. Fifth, because of the higher dimensionality and potentially large number of interactions, information needed to quantify risk is typically incomplete, necessitating an uncertainty analysis. Three approaches that could be used for characterizing risks in a CRA are presented: the multiroute hazard index, stressor grouping by exposure and toxicity, and indices for screening multiple factors and conditions. Other key roles of the risk characterization in CRAs are also described, mainly the translational aspect of including a characterization summary for lay readers (in addition to the technical analysis), and placing the results in the context of the likely risk-based decisions. PMID- 29168989 TI - Should I Stay or Should I Go Now? Or Should I Wait and See? Influences on Wildfire Evacuation Decisions. AB - As climate change has contributed to longer fire seasons and populations living in fire-prone ecosystems increase, wildfires have begun to affect a growing number of people. As a result, interest in understanding the wildfire evacuation decision process has increased. Of particular interest is understanding why some people leave early, some choose to stay and defend their homes, and others wait to assess conditions before making a final decision. Individuals who tend to wait and see are of particular concern given the dangers of late evacuation. To understand what factors might influence different decisions, we surveyed homeowners in three areas in the United States that recently experienced a wildfire. The Protective Action Decision Model was used to identify a suite of factors previously identified as potentially relevant to evacuation decisions. Our results indicate that different beliefs about the efficacy of a particular response or action (evacuating or staying to defend), differences in risk attitudes, and emphasis on different cues to act (e.g., official warnings, environmental cues) are key factors underlying different responses. Further, latent class analysis indicates there are two general classes of individuals: those inclined to evacuate and those inclined to stay, and that a substantial portion of each class falls into the wait and see category. PMID- 29168990 TI - Model-Based Meta-Analysis for Multiple Myeloma: A Quantitative Drug-Independent Framework for Efficient Decisions in Oncology Drug Development. AB - The failure rate for phase III trials in oncology is high; quantitative predictive approaches are needed. We developed a model-based meta-analysis (MBMA) framework to predict progression-free survival (PFS) from overall response rates (ORR) in relapsed/refractory multiple myeloma (RRMM), using data from seven phase III trials. A Bayesian analysis was used to predict the probability of technical success (PTS) for achieving desired phase III PFS targets based on phase II ORR data. The model demonstrated a strongly correlated (R2 = 0.84) linear relationship between ORR and median PFS. As a representative application of the framework, MBMA predicted that an ORR of ~66% would be needed in a phase II study of 50 patients to achieve a target median PFS of 13.5 months in a phase III study. This model can be used to help estimate PTS to achieve gold-standard targets in a target product profile, thereby enabling objectively informed decision-making. PMID- 29168991 TI - An Assessment of the Cox Proportional Hazards Regression Model for Epidemiologic Studies. AB - The basic assumptions of the Cox proportional hazards regression model are rarely questioned. This study addresses whether hazard ratio, i.e., relative risk (RR), estimates using the Cox model are biased when these assumptions are violated. We investigated also the dependence of RR estimates on temporal exposure characteristics, and how inadequate control for a strong, time-dependent confounder affects RRs for a modest, correlated risk factor. In a realistic cohort of 500,000 adults constructed using the National Cancer Institute Smoking History Generator, we used the Cox model with increasing control of smoking to examine the impact on RRs for smoking and a correlated covariate X. The smoking associated RR was strongly modified by age. Pack-years of smoking did not sufficiently control for its effects; simultaneous control for effect modification by age and time-dependent cumulative exposure, exposure duration, and time since cessation improved model fit. Even then, residual confounding was evident in RR estimates for covariate X, for which spurious RRs ranged from 0.980 to 1.017 per unit increase. Use of the Cox model to control for a time-dependent strong risk factor yields unreliable RR estimates unless detailed, time-varying information is incorporated in analyses. Notwithstanding, residual confounding may bias estimated RRs for a modest risk factor. PMID- 29168993 TI - Brain Injury in Term Infants: The 'Each Baby Counts' Programme.

AB - Little data is available on the resource utilisation of patients admitted with Community-Acquired Pneumonia (CAP) in Ireland. A retrospective review of 50 randomly-selected patients admitted to Beaumont Hospital with CAP was undertaken. The mean length of stay of patients with CAP was 12 days (+/- 16 days). All patients were emergency admissions, all had a chest x-ray, a C-reactive protein blood test, and occupied a public bed at some point during admission. Common antimicrobial therapies were intravenous (IV) amoxicillin/clavulanic acid and oral clarithromycin; 60% received physiotherapy. The estimated mean cost of CAP per patient was ?14,802.17. Costs arising from admission to hospital with CAP are substantial, but efforts can be undertaken to ensure that resources are used efficiently to improve patient care such as discharge planning and fewer in hospital ward transfers. PMID- 29168996 TI - Cancer Incidence and Mortality due to Excess Body Weight in Ireland: An Analysis of 10-year data. AB - Excess body weight (EBW) increases the risk of specific cancers. The prevalence of EBW has risen significantly in Ireland over recent decades. To highlight the impact on cancer, and to inform future policies, we calculated the proportion of cancers in Ireland that were attributable to EBW using the Population Attributable Fraction (PAF). This fraction was then applied to Irish incidence and mortality data for specific cancers from 2003-2012 to estimate the number of new cancers and cancer deaths attributable to EBW. We found that each year in Ireland, approximately 800 new cancers and 300 cancer deaths are attributable to EBW. The greatest attributable risk of cancer was seen for the upper digestive tract and endometrium, whilst breast and colorectal have the greatest numbers of attributable cancers. EBW is a major cause of cancer, responsible for 4.5% of all cancers in Ireland. Public awareness of this significant preventable risk must improve. PMID- 29168997 TI - A Retrospective Audit of In-Hospital 30-day Mortality from Acute Myocardial Infarction in Connolly Hospital Blanchardstown. AB - In 2015, The Department of Health published the first annual report of the "National Healthcare Quality Reporting System." Connolly Hospital was reported to a mortality rate within 30 days post-Acute Myocardial Infarction (AMI) of 9.87 per 100 cases which was statistically significantly higher than the national rate. We carried out a retrospective audit of patients who were HIPE-coded as having died within 30 days of AMI from 2011-2013 and identified 42 patients. On review, only 23 patients (54.8%) were confirmed as having had an AMI. We identified 12 patients who had AMI included on death certificate without any evidence for same. If the 22 patients incorrectly coded were excluded, the mortality rate within 30 days post-AMI in CHB would fall to 4.14 deaths per 100 cases, well below the national average. Inaccuracies of data collection can lead to erroneous conclusions when examining healthcare data. PMID- 29168998 TI - Three year Experience of Non-Melanoma Skin Cancer in a General Practice. AB - We report 85 lesions of non-melanoma skin cancer in 58 patients, representing 9% of the minor surgical workload of a single general practitioner. Cases were studied in order to describe pathology, management and outcomes. Eighteen percent of lesions were referred, mainly because of central facial site and larger size. Of the lesions treated in the surgery, all but four were treated surgically. Quantitative margins of lateral and deep excision were reported for 50% and 30% of specimens respectively. Lateral histological margins of clearance were narrower for head and neck lesions. Incomplete excision occurred in 4%. There was one recurrent lesion after two years of follow-up. A majority of non-melanoma skin cancers at this clinic were managed safely without referral to secondary care. Quantitative reporting of tumour free margins for skin cancer is lacking.

AB - Gestational Diabetes Mellitus (GDM) is a growing concern and poses serious health risks to both mother and child1. The current study explores the psychological determinants of exercise behaviour in a sample of pregnant women with GDM. A cross-sectional survey design was employed to examine exercise behaviour, illness perceptions, perceived barriers and benefits, exercise beliefs, and exercise self efficacy using validated questionnaires. A sample of 46 pregnant women was recruited from University College Hospital Galway, Letterkenny General Hospital, Cork University Hospital and Mayo General Hospital in Castlebar. Participant's varied; age (22-44 years), body mass index (19-41). High mean scores for Personal Control (24.5) and Treatment Control (30.2) subscales indicated strongly held positive beliefs in relation to controllability of the illness. Total MET min/week score was not related to any psychological variables. Analysis of the IPQ-R data revealed 'diet' (n=37, 80.4%) as the most referred to cause of diabetes. Exercise belief data identified "managing weight gain" (n= 21, 45.7%), and "losing baby weight" (n= 31, 67.4%) as the most frequent beliefs for engaging in physical activity during pregnancy and post pregnancy. Further research on the psychological determinants of physical activity behaviour among this population group is needed in order to create successful intervention strategies. PMID- 29169000 TI - Hidradenitis Suppurativa and Crohn's Disease: A Case Series. AB - Hidradenitis Suppurativa (HS) is characterized by chronic recurrent abscesses, nodules and draining sinus tracts with scar formation. Cutaneous Crohn's Disease (CD) may also present similarly. We wished to identify and describe an Irish cohort with combined HS and CD, with a view to a better recognition of clinical manifestations and understanding of the pathophysiology underlying these two overlapping conditions. Cases were identified using the HIPE Code at Tallaght Hospital from 1990-2014 and retrospective review was performed. Seven patients with both HS and CD were identified, 5(71%) female. The median age of diagnosis with both conditions was 37 years. In all cases, CD had preceded the diagnosis of HS. All patients smoked. Six had an increased BMI and 43% had additional autoimmune conditions. All patients required treatment with a TNF-alpha inhibitor for HS with 5 of 6 subjects having reduced frequency of flare ups and clinically less active HS on follow up.

AB - In Ireland, Ivacaftor is reimbursed, on the High-Tech Drug Scheme, for the treatment of cystic fibrosis in patients age 6 years and older who have the G551D mutation. The aim of this study was to analyse the utilisation and expenditure of Ivacaftor on this scheme in the 12 month period post-reimbursement. All patients who had received Ivacaftor (regardless of General Medical Services Scheme eligibility/ineligibility) were included. A total of 140 individuals (male=74; 53%) received Ivacaftor over the defined 12 month study period (from January 2015 to December 2015 inclusive). The cohort ranged in age from 6 years to 61 years. The mean age was 22 years; a positive skew in age distribution indicated that a greater number of the cohort were in the younger age groups. No statistically significant difference was detected in the mean ages of the male and female subgroups. Drug acquisition expenditure by the Health Services Executive on Ivacaftor over the 12 month study period was ?29.81 million. PMID- 29169002 TI - Skin Cancer Awareness Amongst Irish Golfers. AB - Aim The aim of this study was to assess skin cancer awareness and identify the UV protective measures used by golfers within the Munster region of Ireland. Methods Subjects were recruited from throughout the Munster region at a regional competition, and at three other local golf clubs and "pro" shops. Participants filled out a short anonymous validated questionnaire when collecting their score cards7. Results One hundred and sixty-three golfers completed the questionnaire with a mean age of 65.6 years. 137 (84%) were male and 26 (16%) were female. We noted a high incidence of both non-melanoma and melanoma skin cancer in our subjects. Sixteen (9.8%) had a previous history of skin cancer, with 8 melanomas and 8 non-melanoma skin cancers. A high percentage, 85%, of the golfers surveyed were compliant with SPF use. However many were using too low a SPF, 63 (44%) were using a SPF less than 30. Knowledge of risk of skin cancer is better amongst the golfers surveyed when compared to the general population. Most respondents (N = 96 (59%)) were aware that melanoma can lead to death if left untreated and 114 (70%) recognized that melanoma can be cured if treated early. Conclusion Golfers may benefit from targeted education emphasizing the importance of higher SPF use. Other interventions that may benefit this population would include availability of sunscreens and educational literature in 'pro' shops at golf courses. PMID- 29169003 TI - Growing Old in the Emergency Department. AB - The research team were concerned that older patients requiring emergency admission seemed to wait longer for a hospital bed, and as such were disproportionately affected by Emergency Department overcrowding. To investigate this theory and explore any changes over time, a ten year dataset (2005-2014 inclusive) was extracted from the information systems at Beaumont Hospital, Dublin. This research examines the changing age profile of ED patients, identifies the relationship between age and the total time spent in the Emergency Department (Patient Experience Time (PET)), and examines the public belief that EDs are busiest in winter when reports of overcrowding and elderly patients waiting on trolleys get most media attention. The results highlight that the ED is busy all year round (but for different seasonal reasons) and point to an overdue need to plan for the current and future healthcare of older patients within and beyond acute hospitals.

This prompted additional testing of a total of 8 samples of three different products (Chlorella, Spirulina and Super Greens), for other faecal flora and antimicrobial resistance in any bacteria isolated. All 8 samples cultured enteric flora such as Enterococci, Enterobacteriaceae and Clostridium species. Antimicrobial susceptibility testing revealed one isolate with extended spectrum ?-lactamase (ESBL) activity and one with carbapenemase activity. Clinicians caring for vulnerable patients should be aware of the potential risk of exposure to antimicrobial resistant bacteria associated with these products.

AB - Objectives To describe serious incidents occurring in the management of patient remains after their death. Design Incidents occurring after patient deaths were analysed using content analysis to determine what happened, why it happened and the outcome. Setting The Strategic Executive Information System database of serious incidents requiring investigation occurring in the National Health Service in England. Participants All cases describing an incident that occurred following death, regardless of the age of the patient. Main outcome measures The nature of the incident, the underlying cause or causes of the incident and the outcome of the incident. Results One hundred and thirty-two incidents were analysed; these related to the storage, management or disposal of deceased patient remains. Fifty-four incidents concerned problems with the storage of bodies or body parts. Forty-three incidents concerned problems with the management of bodies, including 25 errors in postmortem examination, or postmortems on the wrong body. Thirty-one incidents related to the disposal of bodies, 25 bodies were released from the mortuary to undertakers in error; of these, nine were buried or cremated by the wrong family. The reported underlying causes were similar to those known to be associated with safety incidents occurring before death and included weaknesses in or failures to follow protocol and procedure, poor communication and informal working practices. Conclusions Serious incidents in the management of deceased patient remains have significant implications for families, hospitals and the health service more broadly. Safe mortuary care may be improved by applying lessons learned from existing patient safety work. PMID- 29169010 TI - Oxidative stress burden inhibits spermatogenesis in adult male rats: testosterone protective effect. AB - In this study, we aimed to investigate the protective effects of androgens, using letrozole (LET; an aromatase inhibitor), grape seed extract (GSE; a naturally occurring aromatase inhibitor and antioxidant), and testosterone propionate (Tp), against methotrexate (MTX)-induced testicular toxicity in adult male rats. MTX has been shown to induce oxidative stress and exhibit antiproliferative effects in the testes. Adult male rats received oral saline gavage (control group with no treatment), the potential protective agents (LET, GSE, or Tp) alone, MTX alone, or a combination of one of the potential protective agents and MTX. The testicular levels of oxidative stress markers and cytokines (tumor necrosis factor-alpha and interleukin-1beta) were measured. Spermatogenesis and sperm viability were microscopically evaluated. Administration of LET and GSE 7 days before MTX improved spermatogenesis and sperm viability, as well as reduced the levels of oxidative stress markers and cellular cytokines. Exogenous testosterone exhibited anti-inflammatory and antioxidant activities, similar to GSE and LET. We also showed that enhancing the endogenous androgenic activity by LET and GSE protected spermatogenesis against MTX-induced testicular toxicity via reduction of inflammation and oxidative stress in the testes. Our data suggest that testosterone protected spermatogenesis owing to its antioxidant and anti inflammatory properties. PMID- 29169011 TI - Objective and subjective measures of exercise intensity during thermo-neutral and hot yoga. AB - While hot yoga has gained enormous popularity in recent years, owing in part to increased environmental challenge associated with exercise in the heat, it is not clear whether hot yoga is more vigorous than thermo-neutral yoga. Therefore, the aim of this study was to determine objective and subjective measures of exercise intensity during constant intensity yoga in a hot and thermo-neutral environment. Using a randomized, crossover design, 14 participants completed 2 identical ~20 min yoga sessions in a hot (35.3 +/- 0.8 degrees C; humidity: 20.5% +/- 1.4%) and thermo-neutral (22.1 +/- 0.2 degrees C; humidity: 27.8% +/- 1.6%) environment. Oxygen consumption and heart rate (HR) were recorded as objective measures (percentage of maximal oxygen consumption and percentage of maximal HR (%HRmax)) and rating of perceived exertion (RPE) was recorded as a subjective measure of exercise intensity. There was no difference in exercise intensity based on percentage of maximal oxygen consumption during hot versus thermo neutral yoga (30.9% +/- 2.3% vs. 30.5% +/- 1.8%, p = 0.68). However, exercise intensity was significantly higher during hot versus thermo-neutral yoga based on %HRmax (67.0% +/- 2.3% vs. 60.8% +/- 1.9%, p = 0.01) and RPE (12 +/- 1 vs. 11 +/- 1, p = 0.04). According to established exercise intensities, hot yoga was classified as light-intensity exercise based on percentage of maximal oxygen consumption but moderate-intensity exercise based on %HRmax and RPE while thermo neutral yoga was classified as light-intensity exercise based on percentage of maximal oxygen uptake, %HRmax, and RPE. Despite the added hemodynamic stress and perception that yoga is more strenuous in a hot environment, we observed similar oxygen consumption during hot versus thermo-neutral yoga, classifying both exercise modalities as light-intensity exercise. PMID- 29169012 TI - Methicillin-resistant Staphylococcus aureus isolated from an intensive care unit in Minas Gerais, Brazil, over a six-year period. AB - To characterize methicillin-resistant Staphylococcus aureus isolates from an intensive care unit of a tertiary-care teaching hospital, between 2005 and 2010. A total of 45 isolates were recovered from patients admitted to the intensive care unit in the study period. Resistance rates higher than 80% were found for clindamycin (100%), erythromycin (100%), levofloxacin (100%), azithromycin (97.7%), rifampin (88.8%), and gentamycin (86.6%). The SCCmec typing revealed that the isolates harbored the types III (66.7%), II (17.8%), IV (4.4%), and I (2.2%). Four (8.9%) isolates carried non-typeable cassettes. Most (66.7%) of the isolates were related to the Brazilian endemic clone from CC8/SCCmec III, which was prevalent (89.3%) between 2005 and 2007, while the USA100/CC5/SCCmec II lineage emerged in 2007 and was more frequent in the last few years. The study showed high rates of antimicrobial resistance among methicillin-resistant S. aureus isolates and the replacement of Brazilian clone, a well-established hospital lineage, by the USA100 in the late 2000s, at the intensive care unit under study.

PMID- 29169013 TI - Body mass index and risk of dementia: Analysis of individual-level data from 1.3 million individuals. AB - INTRODUCTION: Higher midlife body mass index (BMI) is suggested to increase the risk of dementia, but weight loss during the preclinical dementia phase may mask such effects. METHODS: We examined this hypothesis in 1,349,857 dementia-free participants from 39 cohort studies. BMI was assessed at baseline. Dementia was ascertained at follow-up using linkage to electronic health records (N = 6894). We assumed BMI is little affected by preclinical dementia when assessed decades before dementia onset and much affected when assessed nearer diagnosis. RESULTS: Hazard ratios per 5-kg/m2 increase in BMI for dementia were 0.71 (95% confidence interval = 0.66-0.77), 0.94 (0.89-0.99), and 1.16 (1.05-1.27) when BMI was assessed 10 years, 10-20 years, and >20 years before dementia diagnosis. CONCLUSIONS: The association between BMI and dementia is likely to be attributable to two different processes: a harmful effect of higher BMI, which is observable in long follow-up, and a reverse-causation effect that makes a higher BMI to appear protective when the follow-up is short.

PMID- 29169020 TI - Biomarkers of antibiotic resistance genes during seasonal changes in wastewater treatment systems. AB - To evaluate the seasonal distribution of antibiotic resistance genes (ARGs) and explore the reason for their patterns in different seasons and different systems, two wastewater treatment systems were selected and analyzed using high-throughput qPCR. Linear discriminant analysis (LDA) effect size (LEfSe) was used to discover the differential ARGs (biomarkers) and estimate the biomarkers' effect size. We found that the total absolute abundances of ARGs in inflows and excess sludge samples had no obvious seasonal fluctuations, while those in winter outflow samples decreased in comparison with the inflow samples. Eleven differentially abundant ARGs (biomarker genes, BmGs) (aadA5-02, aac-6-II, cmlA1-01, cmlA1-02, blaOXA10-02, aadA-02, tetX, aadA1, ereA, qacEDelta1-01, and blaTEM) in summer samples and 10 BmGs (tet-32, tetA-02, aacC2, vanC-03, aac-6-I1, tetE, ermB, mefA, tnpA - 07, and sul2) in winter samples were validated. According to 16S rRNA gene sequencing, the relative abundance of bacteria at the phylum level exhibited significant seasonal changes in outflow water (OW), and biomarker bacteria (BmB) were discovered at the family (or genus) level. Synechococcus and vadinCA02 are BmB in summer, and Trichococcus, Lactococcus, Pelosinus, Janthinobacterium, Nitrosomonadaceae and Sterolibacterium are BmB in winter. In addition, BmB have good correlations with BmGs in the same season, which indicates that bacterial community changes drive different distributions of ARGs during seasonal changes and that LEfSe is an acute and effective method for finding significantly different ARGs and bacteria between two or more classes. In conclusion, this study demonstrated the seasonal changes of BmGs and BmB at two wastewater treatment systems. PMID- 29169021 TI - Is interference control in children with specific language impairment similar to that of children with autistic spectrum disorder? AB - AIMS: The purpose of the study was to examine resistance to proactive interference, which is strongly associated with working memory (WM) performance and language processing, in children with specific language impairment (SLI), with autism spectrum disorder (ASD), and with typical development (TD). METHODS: Sixty children (eight to ten years; matched in age and nonverbal IQ) participated in the study. Resistance to proactive interference was measured using a verbal conflict paradigm. RESULTS: Children with SLI and ASD show a deficit in resistance to proactive interference compared to their TD peers, but the source of the problem appears to be different for the two clinical groups. The interference problem exhibited by the children with SLI is related to a more complex deficit involving different cognitive-linguistic functions, whereas the children with ASD show a specific problem in cognitive flexibility. IMPLICATIONS: The theoretical implications are that poor resistance to interference may be caused by weaknesses in different WM functions, such as a deficit in updating or responses based on familiarity rather than recollection. The clinical implications are that children with SLI and ASD show distinct patterns of performance; therefore they need different types of intervention to strengthen their resistance to proactive interference. PMID- 29169022 TI - Porous microspheres of polyaniline, poly(o-toluidine), and poly(m-toluidine) prepared from double emulsions stabilized by toluidine isomers as the single surfactant. AB - HYPOTHESIS: Porous spheres of the conducting polymer polyaniline (PANI) and its derivatives are promising materials for use as functional encapsulants for payload delivery and catalyst supports. Stable water-in-oil-in water (W/O/W) double emulsions can be used to obtain this morphology, but typically require multiple surfactants and stabilizers. A single surfactant system that uses a small amphiphilic molecule is desirable, as it can simplify the method, improve its efficiency, and reduce its cost. EXPERIMENTS: Granular poly(o-toluidine) (POT) was transformed into porous microspheres when ammonium hydroxide was added to an aqueous acidic dispersion containing the preformed polymer and amphiphilic o-toluidine (OT). The OT, POT, and ammonium hydroxide concentrations were varied to understand the formation mechanism. Conditions were optimized to obtain a narrowed size distribution. FINDINGS: The rapid change from acidic to alkaline surroundings produces a W/O/W double emulsion from POT and OT over a relatively narrow concentration range. Spheres form when POT dissolves in immiscible OT droplets, and entrapped water droplets form the pores. OT serves as the single amphiphilic surfactant and dissolved POT serves as a hydrophobic co-stabilizer. o Toluidine, m-toluidine, or p-toluidine could be used as the single surfactant to obtain porous spheres from preformed POT, PANI and poly(m-toluidine).

AB - Wearable electronics are developing rapidly in recent years. In this work, we develop a cost-effective, facile, and scalable approach to transform insulating cotton textile to highly conductive Ni-coated cotton textile (NCT). In order to verify the feasibility of NCT as a flexible current collector for wearable supercapacitors, we electrodeposit low-crystalline Ni-Al layered double hydroxide (LDH) nanoparticles onto the NCT. The obtained NCT@NiAl-LDH shows high specific capacitance (935.2 mF cm-2), superior rate capability, and good cyclability. Besides, the asymmetric supercapacitor (ASC) assembled from NCT@NiAl-LDH exhibits high specific energy of 58.8 Wh kg-1 (134 MUWh cm-2) when the specific power is 539 W kg-1 (1228 MUW cm-2). The results demonstrate great potential of our methodology. PMID- 29169024 TI - Self-cleaning superhydrophobic epoxy coating based on fibrous silica-coated iron oxide magnetic nanoparticles. AB - Inspired by the self-cleaning lotus leaf, a facile method of fabricating superhydrophobic silica coated magnetite nanoparticles using a cost-effective process is presented in this work. The structural characterizations and magnetic properties of the obtained core-shell magnetic nanoparticles were characterized by means of X-ray diffraction (XRD), thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). TEM analysis revealed that the particles present flower-like dendrimeric fibers morphology. The particles were uniformly dispersed on the surface of an epoxy resin coating with the purpose to increase the roughness and reduce the surface energy of the surface. The resulting superhydrophobic surface provides robust water-repellent surface under harsh conditions, thanks to its self-cleaning characteristic. The superhydrophobicity of this surface was confirmed based on the measurements of a water contact angle around 175 degrees , which surpasses the theoretical limit of the superhydrophobicity. The simplicity and the cost-effectiveness of the process developed in this study appears to be a promising route for the preparation of other magnetic superhydrophobic organic-inorganic hybrid materials that would be beneficial in a wide variety of applications. PMID- 29169025 TI - Foam and thin films of hydrophilic silica particles modified by beta-casein. AB - HYPOTHESIS: Foaming properties of particle dispersions can be modified by addition of amphiphiles. The molar ratio between particles and amphiphiles will influence the wetting properties of the particles as well as the bulk concentration of the amphiphiles. This will have an effect on air/water interfacial composition as well as on the thin film and foam stability of the mixed system. EXPERIMENTS: In this research foams and thin films of hydrophilic silica particles in presence of beta-casein (beta-CN) were investigated with different particle sizes and varying beta-CN/silica weight ratios (between 1:10 and 1:100). Samples were characterized for particles size, morphology as well as contact angle and related to their foaming, interfacial, and thin film properties. FINDINGS: A threshold weight ratio of beta-CN/silica was found to be 1:50 for foam stabilization with mixtures containing silica particles no larger than 1 MUm and 1:30 for film stabilization with mixtures containing larger particles. At the interface, the modified silica particles were rather diluted without much interaction for surface compressions up to 30%. Large silica particles (0.0015% beta-CN, Csilica <= 0.15%) were dragged to the periphery of the thin liquid films but no decrease of the inner film draining rate by a decrease of capilary pressure gradient across the film was observed. The depletion of beta-casein in the bulk by particles played a major role in foam destabilization. PMID- 29169027 TI - Phase modulated 2D HSQC-TOCSY for unambiguous assignment of overlapping spin systems. AB - We present a new method that allows one to unambiguously resolve overlapping spin systems often encountered in biomolecular systems such as peptides and proteins or in samples containing a mixture of different molecules such as in metabolomics. We address this problem using the recently proposed phase modulation approach. By evolving the 1H chemical shifts in a conventional two dimensional (2D) HSQC-TOCSY experiment for a fixed delay period, the phase/intensity of set of cross peaks belonging to one spin system are modulated differentially relative to those of its overlapping counterpart, resulting in their discrimination and recognition. The method thus accelerates the process of identification and resonance assignment of individual compounds in complex mixtures. This approach facilitated the assignment of molecules in the embryo culture medium used in human assisted reproductive technology.

AB - Smectite clay nanoparticles are implicated in the retention of antimicrobials within soils and sediments; these clays are also inspected as drug carriers in physiological systems. Cation exchange is considered the primary adsorption mechanism of antimicrobials within smectite nanopores. However, a dual role of acid-base chemistry and adsorptive structures is speculated by recent studies. Using the prototypical smectite clay montmorillonite, we employed a combination of X-ray diffraction (XRD), nuclear magnetic resonance, attenuated total reflectance-Fourier transform infrared spectroscopy, and molecular dynamics simulations to investigate the interlayer nanopore trapping of two structurally different fluoroquinolone (FQ) antimicrobials with similar acid-base chemistry: ciprofloxacin (a first-generation FQ) and moxifloxacin (a third-generation FQ). Greater sorption at pH 5.0 than at pH 7.0 for both FQs was consistent with cation exchange of positively-charged species. However, the clay exhibited a near twofold higher sorption capacity for moxifloxacin than for ciprofloxacin. This difference was shown by the XRD data to be accompanied by enhanced trapping of moxifloxacin within the clay interlayers. Using the XRD-determined nanopore sizes, we performed molecular dynamics simulations of thermodynamically-favorable model adsorbates, which revealed that ciprofloxacin was adsorbed parallel to the clay surface but moxifloxacin adopted a tilted conformation across the nanopore. These conformations resulted in more slowly-exchanged than quickly-exchanged Na complexes with ciprofloxacin compared with moxifloxacin. These different Na populations were also captured by 23Na nuclear magnetic resonance. Furthermore, the simulated adsorbates uncovered different complexation interactions that were corroborated by infrared spectroscopy. Therefore, beyond acid-base chemistry, our findings imply that distinct adsorbate structures control antimicrobial trapping within clay nanopores, which can promote persistence in environmental matrices and stable delivery in biological systems.

AB - PURPOSE: Depressive and anxiety disorders are frequent among people with epilepsies. There are, however, only few longitudinal studies, which examine the relationship between these comorbid psychiatric disorders and epilepsy-related variables. Thus, we investigated the interrelationships of depression and anxiety symptoms with seizure frequency across time. METHODS: Before admittance to an epilepsy center (T1) and six months after discharge (T2), patients (n=198) with mainly difficult-to-treat epilepsies completed the Hospital Anxiety and Depression Scale (HADS). Correlation and path analyses were conducted. RESULTS: Depression and anxiety symptoms (HADS) as well as seizure frequency significantly decreased from baseline to follow-up. Both at T1 and T2, seizure frequency was slightly, but significantly correlated with depression and anxiety levels (rs CONCLUSION: The present findings emphasize the importance of psychiatric comorbidities, especially depression, for seizure frequency and its progress in patients with difficult-to-treat epilepsies referred to a specialized epilepsy center. Thus, comorbid psychiatric disorders need specific consideration as part of a comprehensive diagnostic and therapeutic treatment approach.

AB - In this paper, we introduce a simple, yet powerful pipeline for medical image segmentation that combines Fully Convolutional Networks (FCNs) with Fully Convolutional Residual Networks (FC-ResNets). We propose and examine a design that takes particular advantage of recent advances in the understanding of both Convolutional Neural Networks as well as ResNets. Our approach focuses upon the importance of a trainable pre-processing when using FC-ResNets and we show that a low-capacity FCN model can serve as a pre-processor to normalize medical input data. In our image segmentation pipeline, we use FCNs to obtain normalized images, which are then iteratively refined by means of a FC-ResNet to generate a segmentation prediction. As in other fully convolutional approaches, our pipeline can be used off-the-shelf on different image modalities. We show that using this pipeline, we exhibit state-of-the-art performance on the challenging Electron Microscopy benchmark, when compared to other 2D methods. We improve segmentation results on CT images of liver lesions, when contrasting with standard FCN methods. Moreover, when applying our 2D pipeline on a challenging 3D MRI prostate segmentation challenge we reach results that are competitive even when compared to 3D methods. The obtained results illustrate the strong potential and versatility of the pipeline by achieving accurate segmentations on a variety of image modalities and different anatomical regions. PMID- 29169030 TI - Lipoprotein-associated phospholipase A2 and risk of incident peripheral arterial disease: Findings from The Atherosclerosis Risk in Communities study (ARIC). AB - BACKGROUND AND AIMS: Results from prospective studies evaluating the relationship between elevated lipoprotein-associated phospholipase A2 (Lp-PLA2) activity and incident peripheral arterial disease (PAD) have been mixed. We investigated whether higher Lp-PLA2 levels are associated with increased risk of incident PAD and whether PLA2G7 gene variants, which result in lower Lp-PLA2 levels, are associated with reduced risk of incident PAD. METHODS: Our analysis included 9922 participants (56% female; 21% African-American; mean age 63 years) without baseline PAD at ARIC Visit 4 (1996-1998), who had Lp-PLA2 activity measured and were subsequently followed for the development of PAD, defined by occurrence of a PAD-related hospitalization, through 2012. Cox proportional hazard models were performed to determine the association of Lp-PLA2 levels and PLA2G7 gene variants with incident PAD. RESULTS: During a median follow-up of 14.9 years, we identified 756 incident cases of PAD. In analyses adjusting for age, race, and sex, each standard deviation increment in Lp-PLA2 activity (62 nmol/ml/min) was associated with a higher risk of developing PAD (hazard ratio (HR) 1.17; 95% confidence interval (CI) 1.09, 1.26). This association remained significant after additional adjustment for risk factors, other cardiovascular disease, and medication use, but was strongly attenuated (HR: 1.09; 95% CI 1.00, 1.20). PLA2G7 variants were not associated with a lower risk of PAD in both white carriers (HR: 1.21; 95% CI: 0.17-8.56) and African-American carriers (HR: 0.83; 95% CI: 0.41 1.67), although statistical power was quite limited for this analysis, particularly in whites. CONCLUSIONS: While higher Lp-PLA2 activity was associated with an increased risk for incident PAD, it is likely a risk marker largely represented by traditional risk factors. PMID- 29169031 TI - Visceral fat index/percentage body fat ratio is independently associated with proximal aortic dilatation in a middle-aged and aged Chinese population in Liujiang of Guangxi. AB - BACKGROUND AND AIMS: Increased volume of visceral adipose tissue is associated with worsening of cardiovascular disease risk factors that contribute to aortic dilatation. We investigated the effects of visceral fat index (VFI) and VFI/percentage body fat (PBF) ratio on proximal aortic size and proximal aortic dilatation (PAD), to assess whether excess visceral fat deposition is an independent risk factor for PAD. METHODS: 738 participants aged 35 years or more were included in this cross-sectional survey. The sizes of aortic valve annulus (AVA), sinuses of Valsalva (SV), sinotubular junction (STJ), and ascending aorta (AscAo) were measured by transthoracic ultrasound. Multivariate linear regression, binary logistic regression, Bayesian linear regression, and receiver operating characteristic curves were performed to clarify the effects of VFI and VFI/PBF ratio on PAD. RESULTS: There were 78 participants (10.6%) with PAD. VFI and VFI/PBF ratio in the population with PAD was significantly increased, compared to the population without PAD (p < 0.001). However, PBF was not significantly different between the two populations. VFI/PBF ratio was positively associated with sizes of AVA, SV, STJ, and AscAo (p < 0.05), and was independently related to PAD (p < 0.05). A 1-SD increment in VFI/PBF ratio was associated with 13.35-fold increased risk of PAD (odds ratio: 13.35, p < 0.05). CONCLUSIONS: VFI/PBF ratio is independently associated with PAD. An increased proportion of visceral fat may contribute to PAD. VFI/PBF ratio calculation may be used for the preliminary identification of individuals at high risk of PAD in the Chinese population. PMID- 29169032 TI - Altering movement parameters disrupts metacognitive accuracy. AB - Correctly estimating the confidence we should have in our decisions has traditionally been viewed as a perceptual judgement based solely on the strength or quality of sensory information. However, accumulating evidence has demonstrated that the motor system contributes to judgements of perceptual confidence. Here, we manipulated the speed at which participants' moved using a behavioural priming task and showed that increasing movement speed above participants' baseline measures disrupts their ability to form accurate confidence judgements about their performance. Specifically, after being primed to move faster than they would naturally, participants reported higher confidence in their incorrect decisions than when they moved at their natural pace. We refer to this finding as the adamantly wrong effect. The results are consistent with the hypothesis that veridical feedback from the effector used to indicate a decision is employed to form accurate metacognitive judgements of performance. PMID- 29169033 TI - Mapping complex mind states: EEG neural substrates of meditative unified compassionate awareness. AB - Specific mental training cultivates diminished self-reference, encompassing non duality, emptiness, awakened-awareness, and compassionate experiences. We aimed to elucidate the neural substrates of four distinct, interdependent Essence-of Mind states: (1) timelessness, (2) non-preference, non-duality, non conceptualization, (3) the view of luminosity and limitlessness, (4) unified compassionate experience of oneness (stable awakened-awareness). EEG data were collected from 30 advanced meditators concomitant to eyes-open/eyes-closed resting baseline, followed by 60-min of instructed practice. Alpha, beta, and gamma, frequency-spatial EEG-dimensions were analyzed. The results revealed that compared to baseline, current density across frequencies significantly decreased upon meditation onset in self-referential, and executive-control regions. During meditation, gamma-band current density significantly increased from state-1 compared to state-4, within the ACC, precuneus, and superior parietal lobule, whereas beta-band activity increased within the insula. These findings suggest a dissociation between brain regions regulating self-referential vs. executive control processing, during non-dual, compassionate states, characterized by brilliantly awake awareness, free from conceptual thought and "doing". PMID- 29169034 TI - Greater cortical thickness within the limbic visceromotor network predicts higher levels of trait emotional awareness. AB - Previous studies of trait emotional awareness (EA) have not yet examined whether differences in cortical structure might account for differences in EA. Based on previous research on the relationship between EA and both emotion conceptualization and visceromotor control processes, we tested two hypotheses in a sample of 26 healthy participants: that higher EA would be predicted by greater cortical thickness within (1) regions of the default mode network (DMN; linked with conceptualization processes), and/or (2) regions of the limbic network (linked with affect generation and visceromotor control processes). A non significant correlation was found between EA and cortical thickness in the DMN. In contrast, a significant positive correlation was observed between EA and cortical thickness within the limbic network. These findings suggest that the structural integrity of cortical regions involved in the generation of affective bodily reactions may play a more important role in explaining differences in EA than previously thought. PMID- 29169036 TI - Frequency of lethal means assessment among emergency department patients with a positive suicide risk screen. AB - Prior work from surveys and limited populations suggests many emergency department (ED) patients with suicide risk do not have documented lethal means assessments (e.g., being asked about home firearms). The specific objectives of this study were to, in an ED with universal screening for suicide risk: (1) estimate how often ED providers documented lethal means assessment for suicidal patients, and (2) compare patients with and without documented lethal means assessments. We reviewed 800 total charts from a random sample of adults in three a priori age groups (18-34 years; 35-59 years; >= 60 years) with a positive suicide risk screen from 8/2014 to 12/2015. Only 18% (n = 145) had documentation by >= 1 provider of assessment of lethal means access. Among these 145, only 8% (n = 11) had documentation that someone discussed an action plan to reduce access (most commonly changing home storage or moving objects out of the home). Among 545 suicidal patients discharged home from the ED, 85% had no documentation that any provider assessed access to lethal means. Our findings highlight an important area for improving care: routine, documented lethal means assessment and counseling for patients with suicide risk. There is an urgent need for further exploration of barriers and facilitators. PMID- 29169035 TI - Do law enforcement interactions reduce the initiation of injection drug use? An investigation in three North American settings. AB - BACKGROUND: The prevention of drug injecting is often cited as a justification for the deployment of law enforcement and for the continuation of drug criminalization policies. We sought to characterize the impact of law enforcement interactions on the risk that people who inject drugs (PWID) report assisting others with injection initiation in three North American countries. METHODS: Cross-sectional data from PWID participating in cohort studies in three cities (San Diego, USA; Tijuana, Mexico; Vancouver, Canada) were pooled (August 2014 December 2016). The dependent variable was defined as recently (i.e., past six months) providing injection initiation assistance; the primary independent variable was the frequency of recent law enforcement interactions, defined categorically (0 vs. 1 vs. 2-5 vs. >=6). We employed multivariable logistic regression analyses to assess this relationship while controlling for potential confounders. RESULTS: Among 2122 participants, 87 (4.1%) reported recently providing injection initiation assistance, and 802 (37.8%) reported recent law enforcement interactions. Reporting either one or more than five recent interactions with law enforcement was not significantly associated with injection initiation assistance. Reporting 2-5 law enforcement interactions was associated with initiation assistance (Adjusted Odds Ratio=1.74, 95% Confidence Interval: 1.01-3.02). CONCLUSIONS: Reporting interactions with law enforcement was not associated with a reduced likelihood that PWID reported initiating others into injection drug use. Instead, we identified a positive association between reporting law enforcement interactions and injection initiation assistance among PWID in multiple settings. These findings raise concerns regarding the effectiveness of drug law enforcement to deter injection drug use initiation. PMID- 29169037 TI - A nephron model for study of drug-induced acute kidney injury and assessment of drug-induced nephrotoxicity. AB - In this study, we developed a multilayer microfluidic device to simulate nephron, which was formed by "glomerulus", "Bowman's capsule", "proximal tubular lumen" and "peritubular capillary". In this microdevice, artificial renal blood flow was circulating and glomerular filtrate flow was single passing through, mimicking the behavior of a nephron. In this dynamic artificial nephron, we observed typical renal physiology, including the glomerular size-selective barrier, glomerular basement membrane charge-selective barrier, glucose reabsorption and para-aminohippuric acid secretion. To demonstrate the capability of our microdevice, we used it to investigate the pathophysiology of drug-induced acute kidney injury (AKI) and give assessment of drug-induced nephrotoxicity, with cisplatin and doxorubicin as model drugs. In the experiment, we loaded the doxorubicin or cisplatin in the "renal blood flow", recorded the injury of primary glomerular endothelial cells, podocytes, tubular epithelial cells and peritubular endothelial cells by fluorescence imaging, and identified the time dependence, dose-dependence and the death order of four types of renal cells. Then by measuring multiple biomarkers, including E-cadherin, VEGF, VCAM-1, Nephrin, and ZO-1, we studied the mechanism of cell injuries caused by doxorubicin or cisplatin. Also, we investigated the effect of BSA in the "renal blood flow" on doxorubicin-or-cisplatin-induced nephrotoxicity, and found that BSA enhanced the tight junctions between cells and eased cisplatin-induced nephrotoxicity. In addition, we compared the nephron model and traditional tubule models for assessment of drug-induced nephrotoxicity. And it can be inferred that our biomimetic microdevice simulated the complex, dynamic microenvironment of nephron, yielded abundant information about drug-induced-AKI at the preclinical stage, boosted the drug safety evaluation, and provided a reliable reference for clinical therapy. PMID- 29169038 TI - Theranostic 2D ultrathin MnO2 nanosheets with fast responsibility to endogenous tumor microenvironment and exogenous NIR irradiation. AB - The fabrication of functional nanoparticles with unique ultra-sensitivity to endogenous tumor microenvironment (TME) is of great significance for their improved theranostic performance and easy excretion out of the body, which has not been realized among diverse nano-sized photothermal agents for photothermal therapy (PTT) of tumor. In this work, we report on the synthesis of 2D ultrathin MnO2 nanosheets for highly efficient PTT against tumor with ultra-sensitivity to endogenous TME. These ultrathin 2D MnO2 nanosheets show the intriguing characteristic of disintegration and releasing of Mn2+ in response to the mild acidic condition and elevated reducing microenvironment of TME, which has successfully realized the pH- and reducing-responsive T1-weighted magnetic resonance imaging of tumor. Importantly, the high PTT efficiency of 2D MnO2 nanosheets responsive to exogenous NIR irradiation has been systematically demonstrated both in vitro and in vivo for suppressing the tumor growth. This first report on the exploring of TME-sensitive photothermal agents with concurrent diagnostic and therapeutic (theranostic) functions significantly broadens the biomedical application of 2D functional biomaterials, which also promotes the further potential clinical translations of nano-sized photothermal agents. PMID- 29169039 TI - Heteromultivalent targeting of integrin alphavbeta3 and neuropilin 1 promotes cell survival via the activation of the IGF-1/insulin receptors. AB - Angiogenesis strongly depends on the activation of integrins, especially integrin alphavbeta3, and of neuropilin-1 (NRP-1), a co-receptor of VEGFR2. Dual-targeted molecules that simultaneously block both of them are expected have increased anti angiogenic and antitumor activity. Toward this goal, we generated bifunctional 40 nm-sized silica nanoparticles (NPs) coated with controlled amounts of cRGD and ATWLPPR peptides and studied their affinity, selectivity and biological activity in HUVECs. Sub-nanomolar concentrations of NPs grafted either with ATWLPPR alone or in combination with cRGD exhibit potent and specific antagonist activity against VEGFR2/AKT signaling. However, a 1 nM concentration of the cRGD/ATWLPPR heteromultivalent particles (RGD/ATW-NPs) also blocks the phosphorylation of VEGFR2 while co-inducing an unexpected long-lasting activation of AKT via IGF 1R/IR-AKT/GSK3beta/eNOS signaling that stimulates cell survival and abrogates the intrinsic toxicity of silica-NPs to serum-starved HUVECs. We also showed that their repeated intravenous administration was associated with the proliferation of human U87MG tumor cells engrafted in nude mice and a dilatation of the tumor blood vessels. We present biochemical evidence for the complex cross-talk generated by the binding of the heteromultivalent NPs with alphavbeta3-integrin and with NRP1. In particular, we show for the first time that such heteromultivalent NPs can trans-activate IGF-1/insulin receptors and exert dose dependent pro-survival activity. This study demonstrates the difficulties in designing targeted silica-based NPs for antiangiogenic therapies and the possible risks posed by undesirable side effects. PMID- 29169040 TI - Tracking and protection of transplanted stem cells using a ferrocenecarboxylic acid-conjugated peptide that mimics hTERT. AB - In vivo tracking of transplanted stem cells has been a central aim of stem cell therapy. Although many tracking systems have been introduced, no method has yet been validated for clinical applications. We developed a novel sophisticated peptide (GV1001) that mimics hTERT (human telomerase reverse transcriptase) and analysed its ability to track and protect stem cells after transplantation. Ferrocenecarboxylic acid-conjugated GV1001 (Fe-GV1001) efficiently penetrated stem cells with no adverse effects. Moreover, Fe-GV1001 improved the viability, proliferation, and migration of stem cells under hypoxia. After Fe-GV1001 labelled stem cells were transplanted into the brains of rats after stroke, the labelled cells were easily tracked by MRI. Our findings indicate that Fe-GV1001 can be used for the in vivo tracking of stem cells after transplantation into the brain and can improve the efficacy of stem cell therapy by sustaining and enhancing stem cell characteristics under disease conditions. PMID- 29169041 TI - The Shewanella woodyi galactokinase pool phosphorylates glucose at the 6 position. AB - Galactokinases are a class of enzymes which belong to the GHMP (galactokinase, homoserine kinase, mevalonate kinase, and phosphomevalonate kinase) superfamily and catalyse the phosphorylation of galactose in the first step of the Leloir pathway. Here we report the discovery of three enzymes from Shewanella woodyi which have been classified as galactokinases based on sequence similarity. However, each of these enzymes show little to no significant activity towards galactose and instead exhibit a strong preference for glucose. Furthermore, in contrast to the usual galactose-1-phosphate product of the galactokinase catalysed reaction, these enzymes produce glucose-6-phosphate. This radical change in enzyme functionality is postulated to be linked to the mutation of a glycine residue which is conserved in all other sequenced galactokinases. PMID- 29169042 TI - Synthesis of aromatic and indole alpha-glucosinolates. AB - Aromatic and indole glucosinolates are important members of the glucosinolate family of compounds du to their potential medicinal properties. They are known to exert antioxidant and anti-carcinogenic activity either by the natural products themselves, or their metabolic products including indole-3-carbinol and isothiocyanates. Natural glucosinolates are all beta-glucosinolates; however, alpha-glucosinolates are also promising compounds for medicinal applications and hence have to be produced synthetically for any bio-activity studies. Here we report on the successful synthesis of a series of alpha-glucosinolates: alpha neoglucobrassicin, alpha-4-methoxyglucobrassicin, 2,3-dichlorophenyl-alpha glucosinolate for the first time. Testing for anti-inflammatory properties of these synthetic GLs, however, did not yield the expected activity. PMID- 29169043 TI - Promoting father involvement in early home visiting services for vulnerable families: Findings from a pilot study of "Dads matter". AB - Despite mounting evidence on the importance of fathers in children's development, evidence-based perinatal home visitation programs have largely overlooked fathers in the design and delivery of services. This paper describes the design, development, and pilot testing of the "Dads Matter" enhancement to standard home visiting services. Dads Matter is a manualized intervention package designed to fully incorporate fathers into perinatal home visiting services. Twenty-four families were enrolled in a pilot study to assess the feasibility, acceptability, and preliminary outcomes of the intervention. Using a quasi-experimental time lagged design, 12 families received standard home visiting services and completed baseline and four-month post-tests. Home visitor staff were then trained and supervised to implement the Dads Matter enhancement in addition to standard services. Twelve additional families were then enrolled and completed baseline and four-month post-tests. Implementation data indicated that Dads Matter was implemented as planned. Cohen's d scores on outcome measures indicate positive trends associated with Dads Matter in the quality of the mother-father relationship, perceived stress reported by both parents, fathers' involvement with the child, maltreatment indicators, and fathers' verbalizations toward the infant. Effect sizes generally ranged from moderate to large in magnitude and were larger than overall effect sizes of home visitation services alone reported in prior meta-analyses. Dads Matter appears to be a feasible, acceptable, and promising approach to improving fathers' engagement in home visiting services and promoting family and child well-being. PMID- 29169044 TI - Esculentoside A specifically binds to ribosomal protein S3a and impairs LPS induced signaling in macrophages. AB - Esculentoside A (EsA), a saponin isolated from Phytolacca esculenta, is reported as a potent suppressor of pro-inflammatory functions of macrophages. However, little is known about the target proteins of EsA for its anti-inflammatory activity. In the present study, to identify the intracellular target for EsA, affinity resins bearing immobilized EsA were used to capture binding proteins of EsA from RAW264.7 cell lysates. Mass spectrography and Western blot analysis of captured proteins indicated that ribosomal protein S3a preferentially bound to EsA affinity resin. Competition experiment further demonstrated that free EsA can disturb the specific interaction between recombinant RPS3a and affinity resin. Surface Plasmon Resonance analysis confirmed that EsA directly bound to RPS3a. Lentivirus-mediated RNAi RPS3a resulted in suppression of TNF-alpha and IL-6 production and impediment of signal transduction in LPS-stimulated RAW264.7 cells, indicating that RPS3a is required for LPS-triggered signaling during induction of pro-inflammatory cytokines. In addition, EsA inhibited the expression of inflammatory factors more strongly in the case of RPS3a interference. These results suggest that EsA exerts its anti-inflammatory activity by targeting RPS3a and impairing its signaling function. These new findings not only extended our understanding on the intracellular mechanisms of EsA, but also indicated RPS3a as an essential component for LPS-mediated pro inflammatory signaling, thus implying RPS3a as a novel therapeutic target for anti-inflammatory therapy. PMID- 29169045 TI - Optimizing medication use in elderly people in primary care: Impact of STOPP criteria on inappropriate prescriptions. AB - BACKGROUND: STOPP (Screening Tool of Older Person's Prescriptions) criteria have been used in acute care and nursing home settings as a screening tool to assess Potentially Inappropriate Medication (PIM) for elderly people. Furthermore, this tool could help General Practitioners (GPs) to lower PIM frequency in primary care. OBJECTIVE: The aim of the study was to measure the impact of STOPP criteria applied by the GP on prescriptions during a primary care consultation. SETTING, SUBJECTS AND METHOD: Twenty GPs were involved and trained to use STOPP criteria. GPs were asked to use STOPP criteria for elderly patients (>75years old) who were taking at least five different drugs, seen over a two-month period. The rate of PIM according to STOPP criteria was measured before and after training. Prescription quality was compared using the Medication Appropriateness Index (MAI) score. RESULTS: Overall, 172 prescriptions were analyzed. A total of 170 PIM were identified according to STOPP criteria before the intervention. Fifty seven percent of the population (n=98 patients) had at least one PIM. GP's intervention decreased the number of PIM according to STOPP criteria to 106 and was beneficial for 44.9% of the patients (n=44). The mean MAI score of all medications and PIM decreased by 14.3% (p<0.001) and 39.1% (p<0.001) respectively. DISCUSSION CONCLUSIONS: Application of STOPP criteria by GPs is an effective tool to decrease PIM and MAI score in primary care. The generalization of the use of STOPP criteria during GP consultation should be fostered. PMID- 29169046 TI - A novel CCM1/KRIT1 heterozygous deletion mutation (c.1919delT) in a Chinese family with familial cerebral cavernous malformation. AB - BACKGROUND: Cerebral cavernous malformation (CCM) is a relatively rare congenital vascular anomaly in the central venous system. Its inherited form, familial cerebral cavernous malformation (FCCM), is an autosomal-dominant disease with incomplete penetrance. The pathogenic genes of FCCM have been mapped into three loci: CCM1/KRIT1, CCM2/MGC4607, and CCM3/PDCD10. Till now, the genetic basis of FCCM in the Chinese population has yet to be well understood. Herein, we investigated the genetic mutation in a Chinese family with FCCM. CASE REPORT: The proband is a 29-year-old female presenting with a 1-month history of headache. Brain magnetic resonance imaging (MRI) revealed multiple intracranial lesions, the largest one showing a popcorn-like appearance. After a 4-year conservative observation, there was no significant clinical or radiological progression. Family investigation found five of her relatives had multiple CCM lesions. DNA sequencing analysis in the proband disclosed a novel heterozygous deletion mutation (c.1919delT; p.Phe640SerfsX21) in exon 17 of the CCM1/KRIT1 gene. This mutation leads to a frameshift and is predicted to cause a premature termination codon to generate a truncated Krev interaction trapped-1 (Krit1) protein of 659 amino acids. The mutation segregated with the disease in the family. CONCLUSION: The current study identified a novel CCM1/KRIT1 heterozygous deletion mutation (c.1919delT) associated with FCCM. Our findings expand the CCM gene mutation profiles in the Chinese population, which will be beneficial for genetic counseling. PMID- 29169047 TI - Spinal muscular atrophy with progressive myoclonic epilepsy linked to mutations in ASAH1. AB - Spinal muscular atrophy with progressive myoclonic epilepsy (SMA-PME), a rare disorder caused by mutation in the ASAH1 gene, is characterized by progressive muscle weakness and intractable epilepsy. The literature about SMA-PME is very rare and most of the time limited to case reports. Mutation in the ASAH1 gene is also found in another rare syndrome which is Farber disease. We report a case of a 13.5-year-old girl with SMA-PME associated with ASAH1 gene mutation. She presented with progressive muscle weakness, tremor, seizure, and cognitive impairment. Clinical features and electrophysiological investigations revealed a motor neuron disease and generalized epilepsy. The marked difference in disease manifestations may explain why Farber and SMA-PME diseases were not suspected of being allelic conditions. SMA-PME cases with ASAH1 mutation could be treated using therapeutic studies regarding Farber disease. In patients with undefined PME or lower motor neuron disease cases, ASAH1 mutation scans should be studied. PMID- 29169049 TI - Stuttering adults' lack of pre-speech auditory modulation normalizes when speaking with delayed auditory feedback. AB - Auditory modulation during speech movement planning is limited in adults who stutter (AWS), but the functional relevance of the phenomenon itself remains unknown. We investigated for AWS and adults who do not stutter (AWNS) (a) a potential relationship between pre-speech auditory modulation and auditory feedback contributions to speech motor learning and (b) the effect on pre-speech auditory modulation of real-time versus delayed auditory feedback. Experiment I used a sensorimotor adaptation paradigm to estimate auditory-motor speech learning. Using acoustic speech recordings, we quantified subjects' formant frequency adjustments across trials when continually exposed to formant-shifted auditory feedback. In Experiment II, we used electroencephalography to determine the same subjects' extent of pre-speech auditory modulation (reductions in auditory evoked potential N1 amplitude) when probe tones were delivered prior to speaking versus not speaking. To manipulate subjects' ability to monitor real time feedback, we included speaking conditions with non-altered auditory feedback (NAF) and delayed auditory feedback (DAF). Experiment I showed that auditory motor learning was limited for AWS versus AWNS, and the extent of learning was negatively correlated with stuttering frequency. Experiment II yielded several key findings: (a) our prior finding of limited pre-speech auditory modulation in AWS was replicated; (b) DAF caused a decrease in auditory modulation for most AWNS but an increase for most AWS; and (c) for AWS, the amount of auditory modulation when speaking with DAF was positively correlated with stuttering frequency. Lastly, AWNS showed no correlation between pre-speech auditory modulation (Experiment II) and extent of auditory-motor learning (Experiment I) whereas AWS showed a negative correlation between these measures. Thus, findings suggest that AWS show deficits in both pre-speech auditory modulation and auditory-motor learning; however, limited pre-speech modulation is not directly related to limited auditory-motor adaptation; and in AWS, DAF paradoxically tends to normalize their otherwise limited pre-speech auditory modulation. PMID- 29169048 TI - Protein lipoylation: an evolutionarily conserved metabolic regulator of health and disease. AB - Lipoylation is a rare, but highly conserved lysine posttranslational modification. To date, it is known to occur on only four multimeric metabolic enzymes in mammals, yet these proteins are staples in the core metabolic landscape. The dysregulation of these mitochondrial proteins is linked to a range of human metabolic disorders. Perhaps most striking is that lipoylation itself, the proteins that add or remove the modification, as well as the proteins it decorates are all evolutionarily conserved from bacteria to humans, highlighting the importance of this essential cofactor. Here, we discuss the biological significance of protein lipoylation, the importance of understanding its regulation in health and disease states, and the advances in mass spectrometry based proteomic technologies that can aid these studies.

AB - Clivus fractures are usually associated with head blunt trauma due to traffic accident and falls. A 23 - year-old man died immediately after a smash-up while he was stopping on his motorcycle. Post-mortem Computed tomography (PMCT), performed before autopsy, revealed a complex basilar skull base fractures associated with brainstem and cranio-vertebral junction injuries, improving the diagnostic performance of conventional autopsy. Imaging data were re-assessable and PMCT offers the possibility to perform multiplanar and volume rendered reconstructions, increasing forensic medicine knowledge related to traumatic injuries.

In this paper, we employed an endangered fish species (Sinocyclocheilus grahami) in Dianchi Lake, China to evaluate the risks of cell free exudates (MaE) produced by a dominant cyanobacterium (Microcystis aeruginosa) on embryo development, as well as the molecular mechanisms responsible. MaE (3d cultured) caused a reduction of fertilization (35.4%) and hatching (15.5%) rates, and increased mortality rates (<=90.0%) and malformation rate (27.6%), typically accompanied by heart failure. Proteomics analysis revealed that two greatest changed proteins - protein S100A1 (over-expressed 26 times compared with control) and myosin light chain (under-expressed 25 fold) - are closely associated with heart function. Further study revealed that heart failure was due to calcium ion imbalance and malformed cardiac structure. We conclude that harmful secondary metabolites from cyanobacteria may adversely affect embryo development in this endangered fish, and possibly contribute to its disappearance and unsuccessful recovery in Dianchi Lake. Hazardous consequences of substances released by cyanobacteria should raise concerns for managers addressing recovery of this and other imperiled species in affected lakes.

AB - alpha-Amylase from Aspergillus oryzae was immobilized via covalent bonds and by physical interactions on a synthesized titania/lignin novel hybrid support. A temperature of 5 degrees C, a pH of 7.0, an initial enzyme solution concentration of 3.0mg/mL and a 3h process duration were found to be optimal for the highest activity of the immobilized enzyme. Moreover, the effect of temperature, pH, storage time and repeated catalytic cycles on the activity of free and immobilized enzyme was examined. Bound alpha-amylase showed enhanced thermal and chemical stability, and its reusability was also improved. Immobilized alpha amylase retained over 80% of its initial activity when stored for 30days at 4 degrees C. Kinetic parameters of the free and immobilized biocatalyst were calculated and compared. The maximum reaction rate (Vmax) and turnover number (kcat) were slightly lower for the immobilized enzyme than for the free enzyme. It should be clearly stated that this work presents a useful protocol to produce stable and active immobilized alpha-amylase onto titania/lignin hybrid which may also be applied to immobilization of other enzymes.

AB - Tebuthiuron is a phenylurea herbicide widely used in agriculture that can reach the aquatic environments, possibly posing negative effects to the aquatic biota. Phenylurea herbicides, such as diuron, are known to cause estrogenic and anti androgenic effects in fish, but no such effects were yet reported for tebuthiuron exposure. Thus, the aim of this study was to evaluate if tebuthiuron, at environmentally relevant concentrations (100 and 200ng/L) and after 25days of exposure have estrogenic and/or anti-androgenic effects on male of Nile tilapia (Oreochromis niloticus), through the evaluation of plasmatic testosterone (T) and estradiol (E2) levels, brain aromatase (CYP19) levels (western-blot), and by evaluating the histology of the testicles. When compared to the control group, plasmatic T levels decreased about 76% in the animals exposed to 200ng/L of tebuthiuron, while E2 levels increased about 94%, which could be related to a significant increase (77%) in CYP19A1 levels, an enzyme that catalyzes the conversion of androgens into estrogens. Histological analyses of the testicles also demonstrated that tebuthiuron at both tested concentrations caused a decrease in the diameter of the seminiferous tubules and in the diameter of the lumen. Therefore, the gonadosomatic index (GSI) was reduced by 36% % in the animals exposed 200ng/L to tebuthiuron. Indeed, the relative frequency of spermatocytes and spermatids increased respectively 73% (200ng/L) and 61% (100ng/L) in the tebuthiuron exposed animals, possibly due to the impairment of sperm release into the lumen, that was decreased 93% (200ng/L) in the treated animals compared to the control. These results confirm that tebuthiuron causes estrogenic and anti-androgenic effects in Nile tilapias at environmentally relevant concentrations. PMID- 29169054 TI - Reliability and validity of a Coda Motion 3-D Analysis system for measuring cervical range of motion in healthy subjects. AB - In the past two decades, many tools have been reported to measure the cervical range of motion (CROM), but most of the results are controversial in healthy individuals and/or individuals with neck pain. The Coda Motion 3-D Analysis system is a new instrument that measures three-dimensional joint movement. However, measurements of CROM using this system have yet to be conducted. Here, we investigate the reliability and validity of the Coda Motion 3-D Analysis System for measuring CROM in healthy adults. Sixty healthy volunteers were involved in this reliability study. Two trained investigators (M1 and M2) used the Coda Motion 3-D Analysis System to measure CROM. M1 and M2 measured all the volunteers once independently; after a short rest, M1 then measured all of them again. The intraclass correlation coefficient (ICC), standard error of the measurements (SEM), smallest detectable difference (SDD), a scatter diagram, and the limits of agreement (LoAs) were applied to evaluate the inter-tester and intra-tester reliability. Thirty healthy volunteers were involved in this validity study. The cervical flexion and extension ranges of motion were measured simultaneously with both the Coda Motion 3-D Analysis System and X-ray. A scatter diagram, the Pearson correlation coefficient and LoAs were used to evaluate the validity. Excellent intra-tester and inter-tester reliabilities were observed for the Coda Motion 3-D Analysis System (intra-tester ICC: 0.84-0.95, inter-tester ICC: 0.84-0.90). Good validity was achieved in extension and flexion with Pearson correlation coefficients ranging from 0.78 to 0.91. The Coda Motion 3-D Analysis System has excellent reliability for the measurement of CROM and good validity for measurements of flexion and extension in healthy subjects. This system has the potential to be used to measure the normal active CROM in the clinic and is accurate, safe, non-invasive, and radiation free.

AB - This investigation evaluated the progression towards fatigue in two muscles of differing fast- and slow-twitch fiber proportions (abductor pollicis brevis (APB) and vastus lateralis (VL)) when activated by functional electrical stimulation (FES) at three frequencies (10, 35, and 50 Hz). Fatigue was defined as a 50% drop from the initial FES-induced force of 25% maximal voluntary contraction (MVC). Ten healthy adults (mean age: 23.2 +/- 3.0 years) were recruited; participants signed an IRB approved consent form prior to participation. Protocols were developed to evaluate the effects of muscle size, fiber type and FES frequency on total time to fatigue. Results indicated that the predominantly fast-twitch VL fatigued more quickly than the slow-twitch APB at the higher frequencies (p < 0.05), but did not significantly differ with stimulation at 10 Hz. Overall, muscle size and FES frequencies showed some significant interactions when generating a defined force and during fatigue development. Furthermore, it appears that to reduce fatigue, FES treatments should not extend past ~14-16 min for large and small muscle groups, respectively, when the muscle group's optimal stimulation frequency is applied. PMID- 29169056 TI - Engineering microorganisms for improving polyhydroxyalkanoate biosynthesis. AB - Biosynthesis of polyhydroxyalkanoates (PHA) has been studied since the 1920s. The biosynthesis pathways have been well understood and various attempts have been made to improve the PHA biosynthesis efficiency. Recent progresses have been focused on systematic improvements on PHA biosynthesis including changing growth pattern for rapid proliferation, engineering to enlarge cell sizes for more PHA accumulation space, reprogramming the PHA synthesis pathways using optimized RBS and promoter, redirecting metabolic flux to PHA synthesis using CRISPR/Cas9 tools, and very importantly, the employment of non-traditional host such as halophiles for reduced complexity on PHA production. All of the efforts should lead to ultrahigh PHA accumulation, controllable PHA compositions and molecular weights, open and continuous PHA production with gravity separation processes, resulting in competitive PHA production cost. PMID- 29169057 TI - Synthetic social support: Theorizing lay health worker interventions. AB - Levels of social support are strongly associated with health outcomes and inequalities. The use of lay health workers (LHWs) has been suggested by policy makers across the world as an intervention to identify risks to health and to promote health, particularly in disadvantaged communities. However, there have been few attempts to theorize the work undertaken by LHWs to understand how interventions work. In this article, the authors present the concept of 'synthetic socialsupport' and distinguish it from the work of health professionals or the spontaneous social support received from friends and family. The authors provide new empirical data to illustrate the concept based on qualitative, observational research, using a novel shadowing method involving clinical and non-clinical researchers, on the everyday work of 'pregnancy outreach workers' (POWs) in Birmingham, UK. The service was being evaluated as part of a randomized controlled trial. These LHWs provided instrumental, informational, emotional and appraisal support to the women they worked with, which are all key components of social support. The social support was 'synthetic' because it was distinct from the support embedded in spontaneous social networks: it was non-reciprocal; it was offered on a strictly time-limited basis; the LHWs were accountable for the relationship, and the social networks produced were targeted rather than spontaneous. The latter two qualities of this synthetic form of social support may have benefits over spontaneous networks by improving the opportunities for the cultivation of new relationships (both strong and weak ties) outside the women's existing spontaneous networks that can have a positive impact on them and by offering a reliable source of health information and support in a chaotic environment. The concept of SSS can help inform policy makers about how deploying lay workers may enable them to achieve desired outcomes, specify their programme theories and evaluate accordingly. PMID- 29169058 TI - Cyclic di-AMP in host-pathogen interactions. AB - Cyclic di-AMP (c-di-AMP) is a bacterial signaling nucleotide synthesized by several human pathogens. This widespread and specific bacterial product is recognized by infected host cells to trigger an innate immune response. Detection of c-di-AMP in the host cytosol leads primarily to the induction of type I interferon via the STING-cGAS signaling axis, while being also entangled in the activation of the NF-kappaB pathway. During their long-standing interaction, host and pathogens have co-evolved to control c-di-AMP activation of innate immunity. On the bacterial side, the quantity of c-di-AMP released inside cells allows to manipulate the host response to exacerbate infection by avoiding immune recognition or, at the opposite, by overloading the STING-cGAS pathway. PMID- 29169059 TI - Adsorption of ammonia molecules and humidity on germanane nanosheet-A density functional study. AB - The structural stability and electronic properties of pristine and Ga substituted germanane nanosheet were investigated using the density functional theory technique. The stability of bare and Ga substituted germanane nanosheet is substantiated with formation energy. The energy band gap opens upon hydrogenation on germanene sheet, which is utilized as a sensor material for the detection of NH3 and H2O molecules. The interaction of ammonia and humidity on germanane nanosheet is explored using the projected density of states, Bader charge transfer, adsorption energy, average energy gap variation, energy gap and electron density. The interaction of H2O and NH3 gas molecules on germanane material is studied in atomistic level. The interaction of humidity on pristine germanane nanosheet and NH3 on Ga substituted germanane nanosheet is found to be more favorable. The findings recommend that germanane nanosheet can be utilized as a chemi-resistor for the detection of humidity and trace levels of ammonia gas in the environment. PMID- 29169060 TI - Involuntary autobiographical memories are relatively more often reported during high cognitive load tasks. AB - Recent studies on involuntary autobiographical memories (IAMs) in daily life have shown that they are most frequently reported during daily routines (e.g. while ironing). Such studies have suggested that reporting IAMs may be influenced by the level of the ongoing task demands and availability of cognitive resources. In two studies, we investigated the effects of cognitive load on reporting IAMs. To examine the presumed cognitive load dependency of IAMs, we utilised an often employed experimental paradigm (Schlagman & Kvavilashvili, 2008) to elicit IAMs under conditions that differed in cognitive load. When performing a vigilance task, participants had to interrupt the task each time they experienced any spontaneous mental contents and write them down. We manipulated the level of cognitive load by either instructing (cognitive load group) or not instructing (control group) participants to perform an additional demanding task. We compared the groups on the number of IAMs and other mental contents (non-IAM contents) recorded, as well as on the frequency of IAMs that was calculated as a proportion of IAMs in all mental contents reported by the participant. We expected that if reporting IAMs depends on the level of cognitive demands, then we should observe lower frequency of IAMs in the cognitive load group compared to the control group. Consistently across studies, we observed a lower number of IAMs and non IAM contents in the cognitive load group. However, IAMs unexpectedly constituted a higher percentage of all mental contents when participants were cognitively loaded. Further implications of the cognitive load effects for IAMs research and experimental methodology are discussed. PMID- 29169062 TI - Study on a new design of Tehran Research Reactor for radionuclide production based on fast neutrons using MCNPX code. AB - The aim of this work is to increase the magnitude of the fast neutron flux inside the flux trap where radionuclides are produced. For this purpose, three new designs of the flux trap are proposed and the obtained fast and thermal neutron fluxes compared with each other. The first and second proposed designs were a sealed cube contained air and D2O, respectively. The results of calculated production yield all indicated the superiority of the latter by a factor of 55% in comparison to the first proposed design. The third proposed design was based on changing the surrounding of the sealed cube by locating two fuel plates near that. In this case, the production yield increased up to 70%. PMID- 29169061 TI - Measurement of cross-sections for 14MeV neutron interaction with 175Lu. AB - The cross-sections for 14MeV neutron interaction with 175Lu were precisely measured by the neutron activation and off-line gamma ray technique. The neutron fluence was monitored by the accompanying alpha-particle of the T(d,n)alpha reaction, and the neutron energies were determined by using the cross-section ratio method of 90Zr(n,2n)89Zr to 93Nb(n,2n)92mNb reactions. As a result, the cross-sections of 175Lu(n,2n)174mLu, 175Lu(n,2n)174gLu, 175Lu(n,p)175m+gYb and 175Lu(n,alpha)172Tm reactions have been deduced at En = 14.1 +/- 0.3MeV, 14.5 +/- 0.3MeV and 14.7 +/- 0.3MeV, respectively. Meanwhile, the comparisons between this work and the date reported by other groups previously were also given. For the comparison, it was found that there were nonnegligible discrepancies among these experimental data, as well as for several databases. As a conclusion, present data seem to be more consistent with the database of ENDF/B-VII.1, but trend to be lower than those of JEFF-3.2 and FENDL-3.1b, except the 175Lu(n,2n)174m+gLu reaction which are all in agreement. PMID- 29169063 TI - Measurement of absolute gamma-ray emission probabilities in the decay of 235U. AB - Accurate measurements were performed of the photon emission probabilities following the alpha decay of 235U to 231Th. Sources of highly enriched 235U were characterised in terms of isotopic composition by mass spectrometry and their activities were standardised by means of alpha-particle counting at a low defined solid angle. The standardised sources were subsequently measured by high resolution gamma-ray spectrometry with calibrated high-purity germanium detectors to determine the photon emission probabilities. Four laboratories participated in this work and reported emission probabilities for 33 gamma-ray lines. Most of them agree with previously published evaluated data. In addition, new values are proposed for gamma-lines which have been measured only once in the past. PMID- 29169064 TI - Eukaryotic initiation factor 4F-sidestepping resistance mechanisms arising from expression heterogeneity. AB - There is enormous diversity in the genetic makeup and gene expression profiles between and within tumors. This heterogeneity leads to phenotypic variation and is a major mechanism of resistance to molecular targeted therapies. Here we describe a conceptual framework for targeting eukaryotic initiation factor (eIF) 4F in cancer-an essential complex that drives and promotes multiple Cancer Hallmarks. The unique nature of eIF4F and its druggability bypasses several of the heterogeneity issues that plague molecular targeted drugs developed for cancer therapy. PMID- 29169065 TI - Can postmortem proteolysis explain tenderness differences in various bovine muscles? AB - This study investigated the relationship between postmortem proteolysis, muscle pH decline, sarcomere length (SL), intramuscular fat (IMF) and Warner-Bratzler shear force (WBSF) in four bovine muscles (biceps femoris (BF), infraspinatus (IS), longissimus lumborum (LL), psoas major (PM). The WBSF was low in BF, IS and PM, while LL had a higher value (P<0.001), but still considered as tender. The PM had fastest pH decline (P<0.001), ultimate pH was lowest in LL and PM and highest for IS (P<0.001), sarcomeres were longest for PM and shortest for BF and LL (P<0.001), while IS and PM had more IMF than BF and LL (P=0.038). Troponin T degradation was similar in all muscles after 2d postmortem, however after 13d LL had more degradation than IS (P=0.003). The MMP-2 activity increased during storage (P=0.001), while IS had less activity than the other muscles (P=0.022). Although the variation in proteolytic activity could not explain the variation in WBSF, the study provides useful knowledge for the meat industry for optimising processing and storage procedures for different beef muscles. PMID- 29169066 TI - Shining a light on enzyme promiscuity. AB - Most, if not all, enzymes are capable of catalyzing physiologically irrelevant secondary reactions-termed 'promiscuous' reactions-in addition to the reactions that they have evolved to catalyze. Promiscuous activities can provide the starting point for evolution of new enzymes, both in nature and in the hands of protein engineers. Recent work suggests that the universe of promiscuous activities available in nature is enormous. New high-throughput approaches have significantly advanced our ability to identify promiscuous activities, setting the stage for synthetic biology efforts to construct novel pathways using catalysts derived from promiscuous enzymes via directed evolution. PMID- 29169067 TI - The role of personal resilience and personality traits of healthcare students on their attitudes towards interprofessional collaboration. AB - BACKGROUND: Interprofessional collaboration (IPC) improves communication between healthcare workers and healthcare delivery. Interprofessional education (IPE) is essential in preparing healthcare students for cooperating with other healthcare disciplines in a real work setting. Although higher education settings have a responsibility to provide collaborative healthcare practice to students, IPE has not yet been prompted worldwide as a formal division in health professional education and in Israel IPE among health professions students is scarce. OBJECTIVE: To examine the attitudes of health professions students towards IPC in correlation with their personal resilience and personality traits. DESIGN: A descriptive cross-sectional design was used. SETTING AND PARTICIPANTS: Participants were fourth year nursing, occupational therapy (OT), and physical therapy students studying in an academic undergraduate program at a School of Health Professions in a central university in Israel. METHODS: Attitudes were assessed with a questionnaire consisting of the Interdisciplinary Education Perception Scale, the Connor-Davidson Resilience Scale, the Big Five Inventory of personality dimensions, and a question evaluating students' experience with the PBL (Problem-Based Learning) method. RESULTS: Questionnaires were completed by 184 health professions students. Nursing students' perception of actual cooperation with other professions and their perceived competency and autonomy in their profession were slightly lower than those of other students. Among nursing students, positive correlations were found between competency & autonomy and resilience (p<0.01) and between competency & autonomy and agreeableness (p<0.05). Positive correlations were also found between their perception of actual cooperation with other professions and: resilience (p<0.01), agreeableness (p<0.05), conscientiousness (p<0.05), and openness (p<0.05). Only OT students were familiar with and experienced in the PBL method. This experience with PBL was found correlated with more positive attitudes towards competency and autonomy in the profession and higher positive perception of actual cooperation with other professions. CONCLUSIONS: IPE, including PBL, should be integrated in health professions students' training. PMID- 29169069 TI - Anti-inflammatory agents in peripheral arterial disease. AB - Inflammation is pivotally involved in coronary and peripheral atherosclerotic disease. This established concept is based on both experimental animal models of vascular inflammation and Mendelian randomization studies demonstrating a causal relationship between pro-inflammatory cytokines (e.g. interleukin-6) and cardiovascular disease risk. More recently, the reduction of cardiovascular events by use of an interleukin-1beta inhibitor (canakinumab) has revived interest in the use of anti-inflammatory agents for the treatment of atherosclerotic disease, including peripheral arterial disease. In this mini review article we provide an update on the pleiotropic anti-inflammatory properties of approved drugs for use in cardiovascular disease (e.g. antiplatelets, statins, PCSK9 inhibitors) and discuss the role of targeted or untargeted anti-inflammatory atheroprotection in peripheral arterial disease by agents such as colchicine, methotrexate, anti-TNF-alpha agents and monoclonal antibodies against interleukin-signaling.

AB - BACKGROUND: Camp programs yield positive and lasting benefits for children. Integrating a summer camp into a nurse course with a service learning design fosters learning beyond the classroom and enhances community engagement. OBJECTIVE: The purpose of this study is to describe the nursing students' experience and perceived confidence after completing a service learning nursing course. DESIGN: This is a descriptive, qualitative research study that used reflection and a perceived confidence questionnaire. SETTING: The study was conducted in a school of nursing and surrounding university campus facilities during the diabetes camp. PARTICIPANTS: The participants (n=23) were nursing students who enrolled in the nursing course. METHODS: As part of the course requirements, students completed an eight item question confidence survey before and after the diabetes camp related to diabetes and camp management, and interpersonal abilities with patients, families, and healthcare professionals. Within 48-72h after diabetes camp, the students completed the reflection paper. The pre and post Confidence Surveys were analyzed using a t-test and thematic analysis was used to analyze the reflection paper. RESULTS: Overall, perceived confidence levels increased after completing the service learning course (t= 9.91, p=0.001). Four themes emerged from the qualitative analysis: pre-camp assumptions and fears, growth in confidence, understanding diabetes management in the community, and appreciation for learning beyond the classroom and hospital setting. CONCLUSIONS: This service learning course provided nursing students the ability to not only develop diabetes clinical skills and perceived confidence, but also life skills including teamwork, leadership, and conflict resolution.

AB - Cancer distress screening and subsequent referral for psychosocial intervention has been mandated for continued cancer center accreditation. Increasing emphasis is being placed on the referral component of this mandate, ensuring that patient distress is not only identified but also effectively treated. Many evidence-based interventions exist for cancer distress. Specific interventions can effectively target biopsychosocial impacts of stress and promote adaptive coping, focusing on problem-solving, social support utilization, assertive communication, sexual health and intimacy, adherence to medical and supportive care recommendations, health behavior change, and emotional processing and expression. In randomized clinical trials, specific interventions have also been associated with biological improvements, including neuroendocrine and immune functioning, decreased rates of breast cancer recurrence, and improved survival rates. As cancer treatments advance and patients live longer, it is pertinent to treat the impacts of breast cancer with evidence-based interventions.

These genomes for diverse species including Salmonella, Escherichia coli, Listeria, Campylobacter and Vibrio have provided great insight into the genetic make-up of these pathogens. Numerous government agencies, industry and academia have developed new applications in food safety using WGS approaches such as outbreak detection and characterization, source tracking, determining the root cause of a contamination event, profiling of virulence and pathogenicity attributes, antimicrobial resistance monitoring, quality assurance for microbiology testing, as well as many others.

PMID- 29169073 TI - Difficulty of confining recalcitrant tuberculosis patients in isolation wards in Japan, 2013-2014. AB - OBJECTIVES: In Japan, approximately 7000 smear-positive tuberculosis (TB) cases were reported in 2014. According to the law, such patients must be isolated in a TB ward until they become at least sputum smear-negative. However, there are some recalcitrant patients who are difficult to isolate because of problematic behaviors. This study was conducted to characterize recalcitrant TB patients and determine why they left the hospitals and how they were followed up after they left. STUDY DESIGN: Cross-sectional study. METHODS: We sent a self-administered questionnaire to the hospitals in Japan with over 11 TB isolation beds, asking about recalcitrant TB inpatients from April 2013 through March 2014, in terms of demographic information, the reasons why they left, and how they were followed up. RESULTS: A total of 38 recalcitrant patients were reported, of whom 15 (39.5%) self-discharged, eight (21.0%) were discharged, and 15 (39.5%) were transferred. Thirty-three (86.8%) were males. The main reason (52.6%) why the patients were considered recalcitrant was related to psychiatric problems. However, nine (23.6%) patients physically assaulted or insulted the staff members. Thirty-six (94.7%) were able to continue anti-TB treatment after they left the original hospital. CONCLUSION: Although the number of recalcitrant TB patients who were abusive was small, there should be TB facilities with law enforcement officials readily available to enforce isolation. PMID- 29169074 TI - Flow stagnation volume and abdominal aortic aneurysm growth: Insights from patient-specific computational flow dynamics of Lagrangian-coherent structures. AB - Abdominal aortic aneurysms (AAA) are localized, commonly-occurring dilations of the aorta. When equilibrium between blood pressure (loading) and wall mechanical resistance is lost, rupture ensues, and patient death follows, if not treated immediately. Experimental and numerical analyses of flow patterns in arteries show direct correlations between wall shear stress and wall mechano-adaptation with the development of zones prone to thrombus formation. For further insights into AAA flow topology/growth interaction, a workout of patient-specific computational flow dynamics (CFD) is proposed to compute finite-time Lyapunov exponents and extract Lagrangian-coherent structures (LCS). This computational model was first compared with 4-D phase-contrast magnetic resonance imaging (MRI) in 5 patients. To better understand the impact of flow topology and transport on AAA growth, hyperbolic, repelling LCS were computed in 1 patient during 8-year follow-up, including 9 volumetric morphologic AAA measures by computed tomography angiography (CTA). LCS defined barriers to Lagrangian jet cores entering AAA. Domains enclosed between LCS and the aortic wall were considered to be stagnation zones. Their evolution was studied during AAA growth. Good correlation - 2-D cross-correlation coefficients of 0.65, 0.86 and 0.082 (min, max, SD) - was obtained between numerical simulations and 4-D MRI acquisitions in 6 specific cross-sections from 4 patients. In follow-up study, LCS divided AAA lumens into 3 dynamically-isolated zones: 2 stagnation volumes lying in dilated portions of the AAA, and circulating volume connecting the inlet to the outlet. The volume of each zone was tracked over time. Although circulating volume remained unchanged during 8-year follow-up, the AAA lumen and main stagnation zones grew significantly (8 cm3/year and 6 cm3/year, respectively). This study reveals that transient transport topology can be quantified in patient-specific AAA during disease progression by CTA, in parallel with lumen morphology. It is anticipated that analysis of the main AAA stagnation zones by patient-specific CFD on a yearly basis could help to predict AAA growth and rupture. PMID- 29169075 TI - Maternal intention to exclusively breast feed among mainland Chinese mothers: A cross-sectional study. AB - OBJECTIVE: to examine postpartum maternal recall of their intentions to exclusively breast feed among breastfeeding women and identify its predictors. DESIGN AND SETTING: a cross-sectional descriptive study was conducted in a regional teaching hospital at Guangzhou, China between April 1 and July 14, 2014. PARTICIPANTS: 571 mothers who were within four days after delivery were recruited to the study. MEASUREMENTS: data were collected by four research assistants with maternal intention to breast feed data sheet, the Network Support for Breastfeeding Scale (NSBS), and a socio-demographic data sheet. FINDINGS: greater than half of the mothers (69.5%) intended to exclusively breast feed. The logistic regression analysis revealed six variables which predicted postpartum maternal recall of their intentions to exclusively breast feed. They were support from husband, being breast-fed as an infant, previous breast feeding experience, attending antenatal breast feeding class, time of decision to breast feed, and the rating of the importance of my baby's health. CONCLUSION AND IMPLICATIONS FOR PRACTICE: health care professionals could develop strategies to enhance mothers' intention to exclusively breast feed, such as providing antenatal breast feeding class on internet, a strong focus on the benefits of exclusive breast feeding on the baby's health in the education programme, and more efforts directed toward educating school-aged children and adolescents to modify societal perceptions of what are considered normal infant feeding. Mothers' husband could be encouraged in supporting exclusive breast feeding.

AB - The Niger Delta is one of the largest oil producing regions of the world. Large numbers and volumes of oil spills have been reported in this region. What has not been quantified is the putative exposure of humans and/or the environment to this hydrocarbon pollution. In this novel study, advanced geostatistical techniques were applied to an extensive database of oil spill incidents from 2007 to 2015. The aims were to (i) identify and analyse spill hotspots along the oil pipeline network and (ii) estimate the exposure of the hydrocarbon pollution to the human population and the environment within the Niger Delta. Over the study period almost 90millionlitres of oil were released. Approximately 29% of the human population living in proximity to the pipeline network has been potentially exposed to oil contamination, of which 565,000 people live within high or very high spill intensity sectors. Over 1000km2 of land has been contaminated by oil pollution, with broadleaved forest, mangroves and agricultural land the most heavily impacted land cover types. Proximity to the coast, roads and cities are the strongest spatial factors contributing to spill occurrence, which largely determine the accessibility of sites for pipeline sabotage and oil theft. Overall, the findings demonstrate the high levels of environmental and human exposure to hydrocarbon pollutants in the Niger Delta. These results provide evidence with which to spatially target interventions to reduce future spill incidents and mitigate the impacts of previous spills on human communities and ecosystem health. PMID- 29169078 TI - Amino acids/peptides conjugated heterocycles: A tool for the recent development of novel therapeutic agents. AB - Amino acids/peptide conjugated heterocycles represent an important class of therapeutical agents. Biologically active heterocycles are conjugated with amino acids or peptides to increase the drug resistance. Furthermore, the amino acid/peptide based drugs have low toxicity, ample bioavailability and permeability, modest potency and good metabolic and pharmacokinetic properties. Synthetic amino acid/peptides based heterocyclic conjugates constitute a promising choice for the development of new, less toxic and safer conventional pharmaceutical drugs in the near future. In this review, we discuss and highlight the recent findings of the structural features that encourage biological applications of amino acid/peptides based conjugates.

In molecular docking studies 7p showed excellent interactions with amino acids TYR 473, SER 289, HIE 449, TYR 327, ARG 288, MET 329 and LEU 228. Compound 7p did not cause any damage to the liver without any noteworthy weight gain and may be considered as promising candidates for the development of new antidiabetic agents. PMID- 29169080 TI - Novel and rare prenyllipids - Occurrence and biological activity. AB - The data presented indicate that there is a variety of unique prenyllipids, often of very limited taxonomic distribution, whose origin, biosynthesis, metabolism and biological function deserves to be elucidated. These compounds include tocoenols, tocochromanol esters, tocochromanol acids, plastoquinones and ubiquinones. Additionally, based on the available data, it can be assumed that there are still unrecognized prenyllipids, like prenylquinols fatty acid esters of the hydroquinone ring, including prenylquinol phosphates, and others, whose biological function might be of great importance. Our knowledge of these compounds is not only important from the scientific point of view, but may also be of practical significance to medicine, pharmacy or cosmetics. PMID- 29169081 TI - Transcriptome profiling reveals specific patterns of paclitaxel synthesis in a new Taxus yunnanensis cultivar. AB - The difference in contents of paclitaxel and 10-deacetylbaccatin III (10-DABIII) in needles between wildtype (WT) and a new cultivar (Zhongdayihao, ZD1) of Taxus yunnanensis was examined. Transcriptome profiling was conducted for different tissues of the ZD1 and WT to illustrate the regulation mechanism of paclitaxel biosynthesis. It was observed that average contents of paclitaxel and 10-DABIII in ZD1 were 4 folds and 32 folds higher than those in WT, respectively. More significant elevations of differential expressed genes (DEGs) from paclitaxel biosynthesis pathway were revealed in ZD1 rather than WT, which should be responsible for the higher contents of paclitaxel and 10-DABIII in the ZD1. Special tissues-dependent expression patterns of paclitaxel biosynthesis DEGs in ZD1 compared to WT were unraveled. The relative higher expressions of paclitaxel biosynthesis genes in needles than other tissues supported the higher content of paclitaxel and 10-DABIII content in needles of ZD1. Attenuation of plant hormone signal transduction pathway led to the lower expression of TFs in ZD1 rather than WT. Besides, the significant negative correlations between differential expressed TFs and DEGs from paclitaxel biosynthesis pathway displayed a possibly negative regulation pattern of these TFs on paclitaxel biosynthesis pathway genes. These results provided new insights into the molecular process of paclitaxel synthesis in Taxus. PMID- 29169083 TI - Political aspects of shared reality. AB - The political world permeates people's everyday experiences. In this article, we review recent research concerning how the pursuit, creation, and maintenance of shared reality underlie important political phenomena. We address three general points. First, we discuss how the desire to share reality shapes the political attitudes that people adopt. Second, we outline how the existence of competing representations of reality can lead to prolonged political conflicts that are challenging to overcome. Third, we consider how and why shared reality contributes to social stasis and change. A scientifically informed understanding of how shared reality shapes the political arena will enrich psychological research and facilitate addressing social issues. PMID- 29169082 TI - The safety and efficacy of propofol as a replacement for amobarbital in intracarotid Wada testing of presurgical patients with epilepsy. AB - OBJECTIVE: The intracarotid sodium amytal procedure (the "Wada test") has for many years been the gold standard for language and memory lateralization and remains an important part of presurgical analysis for patients with medically intractable seizures. Due to shortages in the key sedative (amobarbital), neuropsychologists have turned to alternatives such as propofol. Our aim was to investigate the safety and efficacy of propofol relative to amobarbital in the Wada test. METHODS: We performed a retrospective review of the 97 Wada procedures performed at University of Iowa Hospitals and Clinics from 2007 through mid-2015. RESULTS: Propofol produced similar lateralization rates as amobarbital for both language and memory. Similar rates of patients in each group went on to have the resection surgery. With regard to safety, there were no differences found in average rate or severity of adverse effects. None of the demographic characteristics reviewed were predictive of increased risk for either drug. SIGNIFICANCE: These findings support previous studies indicating that propofol is as safe and efficacious as amobarbital, and can continue to be used in Wada procedures with confidence. PMID- 29169084 TI - Changes in first trimester fetal CYP1A1 and AHRR DNA methylation and mRNA expression in response to exposure to maternal cigarette smoking. AB - Prenatal exposure to maternal cigarette smoking increases the risk of intrauterine growth retardation, adverse pregnancy outcomes, and diseases later in life. Exposure can result in postnatal global and gene-specific DNA methylation changes, with the latter well documented for the CYP1A1 and AHRR genes involved in the detoxification of xenobiotic substances. This study assessed the impact of exposure to maternal smoking on first trimester fetal CYP1A1 and AHRR mRNA expression and DNA methylation for CpG-sites displaying maternal smoking during pregnancy-mediated methylation changes at birth. The analyses included first trimester (6-12 weeks) placentas (N=39) and livers (N=43). For AHRR, exposure to maternal smoking was associated with increased DNA methylation in the placentas of female fetuses; mRNA expression, however, was unchanged. While exposure to maternal smoking was not associated with AHRR DNA methylation changes in fetal livers; mRNA expression was increased. For CYP1A1, exposure to maternal smoking was not associated with fetal DNA methylation changes whereas mRNA expression increased in placentas and male fetal livers. These results show that first trimester exposure to maternal smoking is associated with CYP1A1 and AHRR DNA methylation and mRNA expression changes. However, the results also indicate that maternal smoking during pregnancy mediated postnatal CYP1A1 and AHRR DNA methylation changes are not imprinted during the first trimester. PMID- 29169085 TI - Combined toxicity of triclosan, 2,4-dichlorophenol and 2,4,6-trichlorophenol to zebrafish (Danio rerio). AB - Triclosan (TCS), 2,4,6-trichlorophenol (2,4,6-TCP) and 2,4-dichlorophenol (2,4 DCP) are the most prevalent chlorinated phenolic pollutants in aquatic environments. Our results showed LC50 and EC50 values of 0.51, 1.11, 2.45mg/L, and 0.36, 0.74, 1.53mg/L for TCS, 2,4,6-TCP and 2,4-DCP, respectively, to 120hpf zebrafish. The highest TCSD (the mixture of TCS, 2,4,6-TCP and 2,4-DCP) toxicity was observed at a TCS:2,4,6-TCP:2,4-DCP concentration ratio of 1:2:4. LC50 and EC50 values of TCSD mixtures for 120-hpf zebrafish were 2.28 and 1.16mg/L, respectively. Two toxicity assessment methods (Toxic Unit and Mixture Toxicity Index) indicated that TCSD interactions produced partly additive toxicity. TCSD exposure decreased zebrafish hatching rate and led to a series of malformations. Following alkaline phosphatase staining, a large area of vascular ablation was observed with almost complete disappearance of vascular branches and a smaller coverage range. Prominent reddening of the yolk sac and visceral mass after oil red O staining implied that TCSD exposure severely affected fat metabolism. Following acridine orange staining, cell death occurred in eyes while high TCSD concentrations (0.84mg/L) induced cardiovascular circulation dysfunction. Alcian blue staining increased the alpha angle between Meckel's cartilages and beta angle between two ceratobranchial. Basihyal and palatoquadrate became shorter and developmental abnormality or defects occurred in the fifth ceratobranchial. Overall, these results provide a theoretical basis for systematically evaluating the combined toxicity of the prevalent chlorinated phenolic pollutants in real world aquatic environments. PMID- 29169086 TI - Linking dynamic patterns of neural activity in orbitofrontal cortex with decision making. AB - Humans and animals demonstrate extraordinary flexibility in choice behavior, particularly when deciding based on subjective preferences. We evaluate options on different scales, deliberate, and often change our minds. Little is known about the neural mechanisms that underlie these dynamic aspects of decision making, although neural activity in orbitofrontal cortex (OFC) likely plays a central role. Recent evidence from studies in macaques shows that attention modulates value responses in OFC, and that ensembles of OFC neurons dynamically signal different options during choices. When contexts change, these ensembles flexibly remap to encode the new task. Determining how these dynamic patterns emerge and relate to choices will inform models of decision-making and OFC function. PMID- 29169087 TI - Antimicrobial discovery inspired by ecological interactions. AB - Bacteria represent an unparalleled source of antibiotics used to treat infectious diseases. Yet, genome analyses have revealed that their full biosynthetic potential is much larger than expected. Valuable strategies to unearth hidden antibiotics are genome mining, pathway engineering and triggering, as well as co cultivation approaches. Nevertheless, there is growing understanding that it is often essential to consider the ecological context and that there is a great potential for antimicrobial discovery from bacteria engaged in well-defined interactions with other organisms. Various ecological scenarios involving antimicrobial agents are outlined in this review: predator-prey and pathogenic interactions, the protection of insect assets such as offspring and cultivars, as well as host protection in symbiotic relationships with plants, invertebrates and animals/humans. The illustrative examples given reinforce the idea that examination of interactions between organisms can yield new antimicrobial compounds, and ultimately further our understanding of the function of these molecules in the environment. PMID- 29169088 TI - Systematically investigating the impact of medication on the gut microbiome. AB - In the recent years, there is accumulating evidence for a strong impact of medication on the gut microbiota composition. This evidence comes from metagenomics-based associations and extends beyond classical antibacterials to a handful of human-targeted drugs. To answer whether such effects are direct and explore their consequences in human health, we need to develop experimental platforms that will allow for systematic profiling of drug-microbiota interactions. Here, we discuss approaches, considerations, experimental setups and strategies that can be used to tackle this need, but can be also readily transmitted to related questions in the microbiome field. A comprehensive understanding of how therapeutics interact with gut microbes will open up the path for further mechanistic dissection of such interactions, and ultimately improve not only our understanding of the gut microbiome, but also drug safety and efficacy. PMID- 29169089 TI - Effect of organic loading rate on anaerobic co-digestion of rice straw and pig manure with or without biological pretreatment. AB - In this study, rice straw (RS) and pig manure (PM) mixtures with or without bio pretreatment were used as the substrates and digested in a 9 L of anaerobic reactor at Organic loading rates (OLRs) of 0.4-3.1 kg COD/(m3 d). The volumetric methane production rate (VMPR), methane yield and anaerobic stability were comparatively investigated. The results showed the co-anaerobic digestion processes of RS and PM mixture after biological pretreatment were very stable at OLRs of 0.4-2.5 kg COD/(m3 d), and its optimal VMPR and methane yield could reach 0.64 L CH4/(L d) and 0.4557 L CH4/g CODremoved at OLR of 2.5 kg COD/(m3 d), which were 62.4% and 37.8% higher than those of the control under the same OLR condition. This study indicated the biological pretreatment with a cellulolytic microbial consortium own great potential in improving the methane yield and productivity of RS and PM wastes. PMID- 29169090 TI - Optimization of Fe2+ supplement in anaerobic digestion accounting for the Fe bioavailability. AB - Fe is widely used as an additive in anaerobic digestion, but its bioavailability and the mechanism by which it enhances digestion are unclear. In this study, sequential extraction was used to measure Fe bioavailability, while biochemical parameters, kinetics model and Q-PCR (fluorescence quantitative PCR) were used to explore its mechanism of stimulation. The results showed that sequential extraction is a suitable method to assess the anaerobic system bioavailability of Fe, which is low and fluctuates to a limited extent (1.7 to -3.1wt%), indicating that it would be easy for Fe levels to be insufficient. Methane yield increased when the added Fe2+ was 10-500mg/L. Appropriate amounts of Fe2+ accelerated the decomposition of rice straw and facilitated methanogen metabolism, thereby improving reactor performance. The modified Gompertz model better fitted the results than the first-order kinetic model. Feasibility analysis showed that addition of Fe2+ at <=50mg/L was suitable. PMID- 29169091 TI - Effects of sulphur on the performance of an anaerobic membrane bioreactor: Biological stability, trace organic contaminant removal, and membrane fouling. AB - This study investigated the impact of sulphur content on the performance of an anaerobic membrane bioreactor (AnMBR) with an emphasis on the biological stability, contaminant removal, and membrane fouling. Removal of 38 trace organic contaminants (TrOCs) that are ubiquitously present in municipal wastewater by AnMBR was evaluated. Results show that basic biological performance of AnMBR regarding biomass growth and the removal of chemical oxygen demand (COD) was not affected by sulphur addition when the influent COD/SO42- ratio was maintained higher than 10. Nevertheless, the content of hydrogen sulphate in the produced biogas increased significantly and membrane fouling was exacerbated with sulphur addition. Moreover, the increase in sulphur content considerably affected the removal of some hydrophilic TrOCs and their residuals in the sludge phase during AnMBR operation. By contrast, no significant impact on the removal of hydrophobic TrOCs was noted with sulphur addition to AnMBR. PMID- 29169092 TI - Triterpenoids with antiplatelet aggregation activity from Ilex rotunda. AB - Phytochemical studies on the barks of Ilex rotunda Thunb. had resulted in the isolation of seven previously undescribed triterpenoids, rotundinosides E-K, along with sixteen known ones. The structures of previously undescribed compounds were elucidated on the basis of extensive spectroscopic analysis and the sugar moieties were further identified by HPLC and GC after acid hydrolysis. Among the isolates, rotundinoside F featured a rare triterpene-phenylpropanoid hybrid structure and rotundinoside H was an uncommon triterpene saponin with alpha linked glucopyranosyl moiety at C-3. The antiplatelet aggregation of all compounds were evaluated against ADP induced rat platelet aggregation in vitro, and five compounds exhibited moderate inhibitory effects with IC50 values ranging from 22.4 to 32.8 MUM. PMID- 29169093 TI - The removal of fluoride from aqueous solution by a lateritic soil adsorption: Kinetic and equilibrium studies. AB - The use of natural sorbents to remove fluoride from drinking water is a promising alternative because of its low-cost and easy implementation. In this article, fluoride adsorption on a latosol soil from Misiones province (Argentina) was studied regarding kinetic and equilibrium aspects. Experiments were conducted in batch at room temperature under controlled conditions of pH 4-8) and ionic strength (1-10mM KNO3). Experimental data indicated that adsorption processes followed a PSO kinetic where initial rates have showed to be influenced by pH solution. The necessary time to reach an equilibrium state had resulted approximately 30min. Equilibrium adsorption studies were performed at pH 8 which is similar to the natural groundwater. For that, fluoride adsorption data were successfully adjusted to Dubinin-Ataskhov model determining that the fluoride adsorption onto soil particles mainly followed a physical mechanism with a removal capacity of 0.48mgg-1. Finally, a natural groundwater was tested with laterite obtaining a reduction close to 30% from initial concentration and without changing significantly the physicochemical properties of the natural water. Therefore, it was concluded that the use of lateritic soils for fluoride removal is very promising on a domestic scale. PMID- 29169094 TI - Evaluation of full pelvic ring stresses using a bilateral static gait-phase finite element modeling method. AB - Trauma to the pelvis is debilitating and often needs fixation intervention. In 58% of patients with this trauma, the injuries can lead to permanent disability, preventing the return to jobs. Of all unsuccessful fixation procedures, 42% are caused by failures of the method, sometimes due to mobilization during healing. Patients would benefit by havibridgetv@comcast.netng fixation hardware in place that enabled ambulation. During walking the bilateral hip joint plus leg and trunk muscle forces, including those from hip motion, can induce torsion into the pelvic ring and across the joint cartilages, and affect the internal stresses of the pelvis. For an accurate understanding, fixation that bridges the bilateral innominate bones needs to be evaluated considering all of these factors, and the affect on the stresses throughout the pelvic ring. Yet there is no bilateral, comprehensive method to do so in the literature. In this study a method was developed that incorporates all of the necessary factors in four bilateral, static, finite element models representing eight gait phases. The resulting stress migration through the full pelvic ring and pubic symphysis displacements were demonstrated under these conditions. In subsequent work, fixation improvements can be applied to these models to evaluate the change in internal stresses, joint displacements and deformations of the hardware, leading to a better quality of design and permitting ambulation during healing for the patient. PMID- 29169095 TI - Bioactivity and properties of an adhesive system functionalized with an experimental niobium-based glass. AB - OBJECTIVE: This study evaluated the incorporation of niobophosphate bioactive glass (NbG) fillers into a commercial adhesive resin. MATERIALS AND METHODS: The silanized (NbGs) or non-silanized (NbG) NbG was added to the commercial adhesive system One Step (OS) at 30% by weight; unfilled adhesive served as control. The bioactivity of adhesives was analyzed by SEM and FTIR/ATR after 28 days in PBS. The adhesives were evaluated as regards microtensile bond strength immediately and after six months (n = 6); degree of conversion (n = 3), microhardness (n = 5); and radiopacity (n = 3). Data from each test were submitted to ANOVA and Tukey tests (P <0.05). RESULTS: FTIR/ATR analysis showed phosphate and carbonate precipitates on the NbG adhesive specimen surface. Statistical analysis of microtensile bond strength values showed that material x time interaction was not significant, but NbG group values were similar to those of unfilled adhesive (p <0.05). Addition of NbG did not alter the degree of conversion, but did increase microhardness and radiopacity values of the adhesive systems compared with those of the control group (OS). Incorporation of NbG into the adhesive system did not compromise the properties of the adhesive. CONCLUSION: A smart adhesive system with bioactive properties, high radiopacity, microhardness, and similar bond strength and degree of conversion was obtained by incorporating 30% by weight of NbG. PMID- 29169096 TI - Neuromuscular compensatory strategies at the trunk and lower limb are not resolved following an ACL reconstruction. AB - BACKGROUND: Following anterior cruciate ligament reconstruction (ACLR), patients present with greater trunk ipsilateral lean, which may affect knee kinetics and increase re-injury risk. However, there has been little research into neuromuscular factors controlling the trunk and their relation to the knee between healthy and ACLR subjects. This is critical to establish in order to develop more directed and effective interventions. HYPOTHESIS: As compared to healthy control subjects, ACLR subjects will demonstrate increased erector spinae and rectus abdominis co-contraction, greater rectus abdominis force and greater hamstring force that is correlated to increased forward trunk lean. STUDY DESIGN: Cross-sectional study, Level of Evidence: 3. METHODS: Eleven healthy and eleven ACLR subjects were matched for age, mass and height. Subjects were asked to run at a self-selected speed while instrumented gait analysis was performed. An anthropometrically scaled OpenSim model was created for each subject. Trunk and hamstring muscle forces from Static Optimization were analyzed at impact peak. Additionally, directed co-contraction ratios were calculated for the erector spinae and erector spinae/rectus abdominis combinations. RESULTS: ACLR subjects showed more balanced erector spinae co-contraction [p<0.01], and greater hamstring force [biceps femoris long head (p=0.02), semimembranosus (0.01), semitendinosus (0.01)]. There was no statistical difference for any other muscle group. CONCLUSION: Despite release to return to sport, ACLR subjects are continuing to increase the stiffness of their trunk as well increase their hamstring force to potentially reduce anterior tibial translation. CLINICAL RELEVANCE: Clinicians may anticipate ACLR subjects using their erector spinae and hamstrings to maintain a sense of stability in their trunk and at their knee. PMID- 29169097 TI - Altered postural control variability in older-aged individuals with a history of lateral ankle sprain. AB - The current study aimed to examine postural control performance during a single leg balance task in elderly individuals with and without a previous history of lateral ankle sprain (LAS). Eighteen adults with a previous history of LAS (mean age = 66 years old) and 12 healthy controls (mean age = 65 years old) were included in the study. Participants performed three trials of a single-leg balance task during an eyes-opened condition for 20-s. Center of pressure (COP) trajectories in the anteroposterior (AP) and mediolateral (ML) directions were collected with a force plate. The following postural control measures were calculated in the AP and ML directions: 1) Sample Entropy (SampEn); 2) Approximate Entropy (ApEn); 3) mean of Time-to-Boundary minima (mean TTB); and 4) COP velocity (COPV). Older-age participants with a history LAS exhibited lower ApEn-AP, SampEn-AP, and SampEn-ML values compared to healthy controls (p < 0.05). The information gained from this investigation indicates more rigid postural control patterns, less adaptability, and more difficulty maintaining COP during a single-leg balance task in adults with a previous history of LAS. Our data suggest that there is a need to consider history of musculoskeletal injury when evaluating factors for postural control and fall risk in the elderly. Future investigations are needed to assess the effect of LAS on age-related declines in postural control and discern associations between potential risk factors of fall related injuries and LAS in an elderly population. PMID- 29169098 TI - Assessing the effects of seawater temperature and pH on the bioaccumulation of emerging chemical contaminants in marine bivalves. AB - Emerging chemical contaminants [e.g. toxic metals speciation, flame retardants (FRs) and perfluorinated compounds (PFCs), among others], that have not been historically recognized as pollutants nor their toxicological hazards, are increasingly more present in the marine environment. Furthermore, the effects of environmental conditions (e.g. temperature and pH) on bioaccumulation and elimination mechanisms of these emerging contaminants in marine biota have been poorly studied until now. In this context, the aim of this study was to assess, for the first time, the effect of warmer seawater temperatures (Delta = + 4 degrees C) and lower pH levels (Delta = - 0.4 pH units), acting alone or combined, on the bioaccumulation and elimination of emerging FRs (dechloranes 602, 603 and 604, and TBBPA), inorganic arsenic (iAs), and PFCs (PFOA and PFOS) in two estuarine bivalve species (Mytilus galloprovincialis and Ruditapes philippinarum). Overall, results showed that warming alone or combined with acidification promoted the bioaccumulation of some compounds (i.e. dechloranes 602, 604, TBBPA), but also facilitated the elimination of others (i.e. iAs, TBBPA). Similarly, lower pH also resulted in higher levels of dechloranes, as well as enhanced iAs, PFOA and PFOS elimination. Data also suggests that, when both abiotic stressors are combined, bivalves' capacity to accumulate contaminants may be time-dependent, considering significantly drastic increase observed with Dec 602 and TBBPA, during the last 10 days of exposure, when compared to reference conditions. Such changes in contaminants' bioaccumulation/elimination patterns also suggest a potential increase of human health risks of some compounds, if the climate continues changing as forecasted. Therefore, this first study pointed out the urgent need for further research on the effects of abiotic conditions on emerging contaminants kinetics, to adequately estimate the potential toxicological hazards associated to these compounds and develop recommendations/regulations for their presence in seafood, considering the prevailing environmental conditions expected in tomorrow's ocean. PMID- 29169099 TI - Exposure to arsenic in tap water and gestational diabetes: A French semi ecological study. AB - INTRODUCTION: The increase in the prevalence of gestational diabetes mellitus (GDM) and its consequences for mother and children prompts research on their risk factors including environmental factors. Studies on exposure to arsenic (As) in tap water and the risk of GDM have not provided conclusive evidence, particularly when levels of exposure were low (from 10 to 50ug As/L). The main objective of this study was to assess the association between exposure to As in tap water and the risk of GDM. METHODS: A semi-ecological study was conducted from births recorded at the University Hospital of Clermont-Ferrand, France, in 2003, 2006 and 2010. Individual medical/obstetric data were available. As exposure was estimated from the concentrations of As measured during sanitary control of tap water supplied in the mothers' commune of residence (aggregate data). French guidelines for As in tap water were used to identify groups potentially exposed, designated "As +" (>= 10ug As/L) and "As -" (< 10ug As/L). Multivariate logistic regression analysis was performed. RESULTS: 5053 women (5.7% with a GDM) were included. Overall, women in the As + group had a higher risk of GDM than those in the As - group (adjusted OR = 1.62; 95%CI: 1.01-2.53). Stratified analysis of pre pregnancy body mass index (BMI) showed a positive association only for obese or overweight women (adjusted OR = 2.30; 95%CI: 1.13-4.50). CONCLUSION: This French semi-ecological study provides additional arguments for an association between As exposure and the risk of GDM in particular in a context of low exposure. Further studies are needed to assess a potential interaction between As exposure and body mass index. PMID- 29169100 TI - The G2 erosion model: An algorithm for month-time step assessments. AB - A detailed description of the G2 erosion model is presented, in order to support potential users. G2 is a complete, quantitative algorithm for mapping soil loss and sediment yield rates on month-time intervals. G2 has been designed to run in a GIS environment, taking input from geodatabases available by European or other international institutions. G2 adopts fundamental equations from the Revised Universal Soil Loss Equation (RUSLE) and the Erosion Potential Method (EPM), especially for rainfall erosivity, soil erodibility, and sediment delivery ratio. However, it has developed its own equations and matrices for the vegetation cover and management factor and the effect of landscape alterations on erosion. Provision of month-time step assessments is expected to improve understanding of erosion processes, especially in relation to land uses and climate change. In parallel, G2 has full potential to decision-making support with standardised maps on a regular basis. Geospatial layers of rainfall erosivity, soil erodibility, and terrain influence, recently developed by the Joint Research Centre (JRC) on a European or global scale, will further facilitate applications of G2. PMID- 29169101 TI - Contribution of diet and other factors to the observed levels of selected perfluoroalkyl acids in serum among US children aged 3-11 years. AB - Data from National Health and Nutrition Examination Survey for 2013-2014 for children aged 3-11 years (N = 639) were analyzed to evaluate the contribution of diet and other factors in variability associated with the observed levels of seven perfluoroalkyl acids in serum, namely, 2(N-methyl-perfluorooctane sulfonamide) acetic acid (MPAH), perfluorodecanoic acid (PFDE), perfluorononanoic acid (PFNA), perflurorohexane sulfonic acid (PFHxS), linear isomer of PFOA (NPFOA), linear isomer of PFOS (NPFOS), and monomethyl isomer of PFOS (MPFOS). Diet accounted for a low of 18.6% of the total explained variance in the adjusted levels of NPFOA and a high of 72.3% for PFNA. Consumption of meat other than fish and poultry was associated with increased levels of NPFOS (beta = 0.00035, p < 0.01) and MPFOS (beta = 0.00027, p=0.02). However, consumption of fish was associated with decreased levels of PFDE (beta = - 0.00058, p=0.01). Consumption of eggs was associated with higher levels of PFDE (beta = 0.00105, p=0.04). Higher levels of PFHxS were associated with consumption of fruits and juices (beta = 0.00019, p = 0.03). Exposure to environmental tobacco smoke in indoor environments other than home was associated with 12.6% increase in the levels of NPFOA. Boys had higher adjusted geometric mean (AGM) than girls for MPAH (0.88 vs. 0.70ng/mL, p = 0.04) and NPFOS (2.73 vs. 2.27ng/mL, p = 0.04). Non-Hispanic white had higher AGMs than Hispanics for MPAH (0.15 vs. 0.07, p < 0.01), for NPFOA (1.98 vs. 1.64ng/mL, p < 0.01), and MPFOS (1.39 vs. 1.18ng/mL, p = 0.03). Non-Hispanic white also had higher AGM than non-Hispanic Asians and others for PFHxS (0.99 vs. 0.63ng/mL, p < 0.01) and NPFOA (1.98 vs. 1.53ng/mL, p < 0.01). PMID- 29169102 TI - A novel framework to evaluate pedestrian safety at non-signalized locations. AB - This paper proposes a new framework to evaluate pedestrian safety at non signalized crosswalk locations. In the proposed framework, the yielding maneuver of a driver in response to a pedestrian is split into the reaction and braking time. Hence, the relationship of the distance required for a yielding maneuver and the approaching vehicle speed depends on the reaction time of the driver and deceleration rate that the vehicle can achieve. The proposed framework is represented in the distance-velocity (DV) diagram and referred as the DV model. The interactions between approaching vehicles and pedestrians showing the intention to cross are divided in three categories: i) situations where the vehicle cannot make a complete stop, ii) situations where the vehicle's ability to stop depends on the driver reaction time, and iii) situations where the vehicle can make a complete stop. Based on these classifications, non-yielding maneuvers are classified as "non-infraction non-yielding" maneuvers, "uncertain non-yielding" maneuvers and "non-yielding" violations, respectively. From the pedestrian perspective, crossing decisions are classified as dangerous crossings, risky crossings and safe crossings accordingly. The yielding compliance and yielding rate, as measures of the yielding behavior, are redefined based on these categories. Time to crossing and deceleration rate required for the vehicle to stop are used to measure the probability of collision. Finally, the framework is demonstrated through a case study in evaluating pedestrian safety at three different types of non-signalized crossings: a painted crosswalk, an unprotected crosswalk, and a crosswalk controlled by stop signs. Results from the case study suggest that the proposed framework works well in describing pedestrian-vehicle interactions which helps in evaluating pedestrian safety at non-signalized crosswalk locations. PMID- 29169103 TI - Impact of roadway geometric features on crash severity on rural two-lane highways. AB - This study examines the impact of a wide range of roadway geometric features on the severity outcomes of crashes occurred on rural two-lane highways. We argue that crash data have a hierarchical structure which needs to be addressed in modeling procedure. Moreover, most of previous studies ignored the impact of geometric features on crash types when developing crash severity models. We hypothesis that geometric features are more likely to determine crash type, and crash type together with other occupant, environmental and vehicle characteristics determine crash severity outcome. This paper presents an application of multilevel models to successfully capture both hierarchical structure of crash data and indirect impact of geometric features on crash severity. Using data collected in Illinois from 2007 to 2009, multilevel ordered logit model is developed to quantify the impact of geometric features and environmental conditions on crash severity outcome. Analysis results revealed that there is a significant variation in severity outcomes of crashes occurred across segments which verifies the presence of hierarchical structure. Lower risk of severe crashes is found to be associated with the presence of 10-ft lane and/or narrow shoulders, lower roadside hazard rate, higher driveway density, longer barrier length, and shorter barrier offset. The developed multilevel model offers greater consistency with data generating mechanism and can be utilized to evaluate safety effects of geometric design improvement projects. PMID- 29169104 TI - Reconciling ethical and economic conceptions of value in health policy using the capabilities approach: A qualitative investigation of Non-Invasive Prenatal Testing. AB - When evaluating new morally complex health technologies, policy decision-makers consider a broad range of different evaluations, which may include the technology's clinical effectiveness, cost effectiveness, and social or ethical implications. This type of holistic assessment is challenging, because each of these evaluations may be grounded in different and potentially contradictory assumptions about the technology's value. One such technology where evaluations conflict is Non-Invasive Prenatal Testing (NIPT). Cost-effectiveness evaluations of NIPT often assess NIPT's ability to deliver on goals (i.e preventing the birth of children with disabilities) that social and ethical analyses suggest it should not have. Thus, cost effectiveness analyses frequently contradict social and ethical assessments of NIPT's value. We use the case of NIPT to explore how economic evaluations using a capabilities approach may be able to capture a broader, more ethical view of the value of NIPT. The capabilities approach is an evaluative framework which bases wellbeing assessments on a person's abilities, rather than their expressed preferences. It is linked to extra-welfarist approaches in health economic assessment. Beginning with Nussbaum's capability framework, we conducted a directed qualitative content analysis of interview data collected in 2014 from 27 Canadian women with personal experience of NIPT. We found that eight of Nussbaum's ten capabilities related to options, states, or choices that women valued in the context of NIPT, and identified one new capability. Our findings suggest that women value NIPT for its ability to provide more and different choices in the prenatal care pathway, and that a capabilities approach can indeed capture the value of NIPT in a way that goes beyond measuring health outcomes of ambiguous social and ethical value. More broadly, the capabilities approach may serve to resolve contradictions between ethical and economic evaluations of health technologies, and contribute to extra-welfarist approaches in the assessment of morally complex health technologies. PMID- 29169105 TI - Constitutive redox and phosphoproteome changes in multiple herbicide resistant Avena fatua L. are similar to those of systemic acquired resistance and systemic acquired acclimation. AB - Plants are routinely confronted with numerous biotic and abiotic stressors, and in response have evolved highly effective strategies of systemic acquired resistance (SAR) and systemic acquired acclimation (SAA), respectively. A much more evolutionarily recent abiotic stress is the application of herbicides to control weedy plants, and their intensive use has selected for resistant weed populations that cause substantial crop yield losses and increase production costs. Non-target site resistance (NTSR) to herbicides is rapidly increasing worldwide and is associated with alterations in generalized stress defense networks. This work investigated protein post-translational modifications associated with NTSR in multiple herbicide resistant (MHR) Avena fatua, and their commonalities with those of SAR and SAA. We used proteomic, biochemical, and immunological approaches to compare constitutive protein profiles in MHR and herbicide susceptible (HS) A. fatua populations. Phosphoproteome and redox proteome surveys showed that post-translational modifications of proteins with functions in core cellular processes were reduced in MHR plants, while those involved in xenobiotic and stress response, reactive oxygen species detoxification and redox maintenance, heat shock response, and intracellular signaling were elevated in MHR as compared to HS plants. More specifically, MHR plants contained constitutively elevated levels of three protein kinases including the lectin S-receptor-like serine/threonine-protein kinase LecRK2, a well-characterized component of SAR. Analyses of superoxide dismutase enzyme activity and protein levels did not reveal constitutive differences between MHR and HS plants. The overall results support the idea that herbicide stress is perceived similarly to other abiotic stresses, and that A. fatua NTSR shares analogous features with SAR and SAA. We speculate that MHR A. fatua's previous exposure to sublethal herbicide doses, as well as earlier evolution under a diversity of abiotic and biotic stressors, has led to a heightened state of stress preparedness that includes NTSR to a number of unrelated herbicides. PMID- 29169106 TI - The transcriptomic changes of Huipizhi Heidou (Glycine max), a nematode-resistant black soybean during Heterodera glycines race 3 infection. AB - Glycine max (soybean) is an extremely important crop, representing a major source of oil and protein for human beings. Heterodera glycines (soybean cyst nematode, SCN) infection severely reduces soybean production; therefore, protecting soybean from SCN has become an issue for breeders. Black soybean has exhibited a different grade of resistance to SCN. However, the underlying mechanism of Huipizhi Heidou resistance against SCN remains elusive. The Huipizhi Heidou (ZDD2315) and race 3 of Heterodera glycines were chosen to study the mechanism of resistance via examination of transcriptomic changes. After 5, 10, and 15days of SCN infection, whole roots were sampled for RNA extraction, and uninfected samples were simultaneously collected as a control. 740, 1413, and 4925 genes were isolated by padj (p-value adjusted)<0.05 after 5, 10, and 15days of the infection, respectively, and 225 differentially expressed genes were overlapped at all the time points. We found that the differentially expressed genes (DEGs) at 5, 10, and 15days after infection were involved in various biological function categories; in particular, induced genes were enriched in defense response, hormone mediated signaling process, and response to stress. To verify the pathways observed in the GO and KEGG enrichment results, effects of hormonal signaling in cyst-nematode infection were further examined via treatment with IAA (indo-3-acetic acid), salicylic acid (SA), gibberellic acid (GA), jasmonic acid (JA), and ethephon, a precursor of ethylene. The results indicate that five hormones led to a significant reduction of J2 number in the roots of Huipizhi Heidou and Liaodou15, representing SCN-resistant and susceptible lines, respectively. Taken together, our analyses are aimed at understanding the resistance mechanism of Huipizhi Heidou against the SCN race 3 via the dissection of transcriptomic changes upon J2 infection. The data presented here will help further research on the basis of soybean and cyst-nematode interaction. PMID- 29169107 TI - Mechanistic insights into alginate fouling caused by calcium ions based on terahertz time-domain spectra analyses and DFT calculations. AB - Fouling mechanisms underlying the filtration behaviors of alginate solution caused by calcium addition were investigated by Terahertz time-domain spectroscopy (THz-TDS) and density functional theory (DFT) techniques. Filtration tests showed that specific filtration resistance (SFR) of alginate solution (0.75 g L-1) monotonously increased with calcium addition at a relatively low range of calcium concentration (0-1.0 mM), and SFR (2.61 * 1015 m kg-1) of alginate solution with 1.0 mM calcium addition was extremely high as compared with sludge suspension. Characterizations by X-ray photoelectric spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR) and Thermogravimetric analysis (TGA) showed that the composition of functional groups, elements and thermal stability of alginate was not apparently affected by calcium concentration. Howbeit, THz TDS spectra showed that calcium addition caused structural variation of alginate polymer in solution. DTF calculation results showed that initial binding of alginate chains induced by calcium ions preferentially occurred in intermolecular other than intramolecular, and moreover, the two alginate chains bridged by a calcium atom tend to stretch in a tetrahedron structure (cross to each other) other than parallel to each other. According to these results, "chemical potential gap" depicted by Flory-Huggins theory was suggested to be responsible for the filtration behaviors of alginate solution caused by calcium addition. This study provided the mechanistic insights into membrane fouling. PMID- 29169108 TI - Identification of mutagenic transformation products generated during oxidation of 3-methyl-4-nitrophenol solutions by orbitrap tandem mass spectrometry and quantitative structure-activity relationship analyses. AB - We used Ames assays to investigate the effects of ozonation (designated O3), ozonation followed by chlorination (O3/Cl), an advanced oxidation process (AOP, UV/H2O2), and AOP followed by chlorination (AOP/Cl) on the mutagenicity of solutions of 3-methyl-4-nitrophenol (3M4NP), a major environmental degradation product of the organophosphorus insecticide fenitrothion. Whereas O3 did not induce mutagenicity, O3/Cl, AOP, and AOP/Cl converted 3M4NP into mutagenic transformation products (TPs). Using liquid chromatography-mass spectrometry, we detected a total of 138 peaks in the solutions subjected to O3/Cl, AOP, and AOP/Cl. To elucidate the TPs responsible for the observed mutagenicity, we performed simple regression analyses of the relationship between the area of each peak and the observed mutagenicity of samples withdrawn periodically during each oxidation process. The area of each of 10 peaks was found to be positively correlated (r2 >= 0.8) with the observed mutagenicity, suggesting that the TPs corresponding to these peaks contributed to the mutagenicity. After taking into account the consistency of mutagenicity induction by the oxidation processes and analyzing the peaks by tandem mass spectrometry, we identified 3 TPs, corresponding to 6 peaks, as candidate mutagens. These TPs were assessed by means of 4 quantitative structure-activity relationship (QSAR) models, and all 3 were predicted to be mutagenic by at least one model. This result was consistent with our assumption that these TPs were mutagens. Ames assays of an authentic sample of one of the 3 TPs revealed that it did not contribute to the mutagenicity. This left 3-methoxy-4-nitrophenol and 2-[(E)-[(2,5-dihydroxyphenyl) methylidene]amino] 5-dihydroxybenzaldehyde on the list of mutagens suspected of contributing to the mutagenicity induced by AOP. No TPs were identified as candidate mutagens responsible for the mutagenicity induced by O3/Cl and AOP/Cl. PMID- 29169109 TI - Mechanism and efficiency of contaminant reduction by hydrated electron in the sulfite/iodide/UV process. AB - Advanced reduction by the extremely strong reducing species, hydrated electron (eaq-), is a promising and viable approach to eliminate a wide variety of persistent and toxic contaminants. In this study, we proposed a sulfite/iodide/UV process, which offered efficient production of eaq- for contaminant reduction. Using monochloroacetic acid (MCAA) as a simple eaq- probe, the availability of eaq- was assessed, and the mechanism involving the roles of S(IV) and iodide in the process was elucidated. A pronounced synergistic effect of S(IV) and iodide was observed in MCAA reductive dechlorination. The efficiency was much more dependent on the iodide concentration due to its higher absorptivity and quantum yield of eaq-. S(IV) played a dual role by producing eaq- via photoionization of SO32- and by reducing the reactive iodine species formed to avoid their scavenging of eaq-. When S(IV) was available, cycling of iodide occurred, favoring the constant eaq- production. The formation and transformation kinetics of sulfite radical were studied to verify the roles of S(IV) and iodide in the process. A kinetic model of MCAA dechlorination was also developed to quantify the eaq--initiated reduction efficiency, highlighting the effects of S(IV), iodide, and pH. High pH favored the reduction, and the process was still effective in field surface water. This study underscores the importance of producing eaq- efficiently and of minimizing the eaq- scavenging of intermediates inherently formed and accumulated, and highlights the potential of the sulfite/iodide/UV process to efficiently eliminate recalcitrant contaminants. PMID- 29169110 TI - Disorder of gut amino acids metabolism during CKD progression is related with gut microbiota dysbiosis and metagenome change. AB - Chronic kidney disease (CKD) is a worldwide public health problem. Uremic retention solutes such as indoxyl sulfate (IS) and p-cresyl sulfate (PCS) are accumulated in CKD patients and are associated with the incidence of CKD progression. Amino acids are the major precursors of uremic retention solutes in gut. The dynamic change of amino acid metabolism in the gut during CKD progression has not been reported previously. In this paper, we studied the dynamic change of gut IS/PCS precursor and amino acid metabolism profile during CKD progression in 5/6 nephrectomized (5/6Nx) rats model. The related gut microbiota and metagenome profile was also studied. Rat plasma, urine and feces were collected at different time points after nephrectomization. Plasma IS and PCS, fecal indole (the precursor of IS), p-cresol (the precursor of PCS) and 19 kinds of amino acids were analyzed by LC-MS. During CKD progression, 5/6 Nx rats showed increased plasma IS, PCS concentration and increased fecal indole, p cresol concentration. 5/6 Nx rats also showed disordered gut amino acids metabolism profile which became more significant along with the progession of CKD. The abundance of some specific gut bacteria also changed significantly in 5/6 Nx rats. The 16S rDNA sequencing data of gut microbiota was further analyzed by an online tool PICRUSt, a large-scale computational method for metagenomes prediction with 16S rDNA sequencing data. The content of each gene was compared between the two groups by Mann-Whitney U test, and then the significantly regulated genes in 5/6 Nx group were subjected to KEGG website. The amino acid metabolism related genes were picked out. Most of these genes are more abundant in 5/6 Nx groups. Our study showed that gut amino acids metabolism profile was disordered with CKD progression, which was highly related to the gut microbiota dysbiosis and metagenome change. And that regulation of gut amino acids metabolism pathway may be a possible way to intervene the progression of CKD. PMID- 29169112 TI - Analysis of unbound plasma concentration of oxcarbazepine and the 10 hydroxycarbazepine enantiomers by liquid chromatography with tandem mass spectrometry in healthy volunteers. AB - This study describes the development and validation of a method for the analysis of unbound plasma concentrations of oxcarbazepine (OXC) and of the enantiomers of its active metabolite 10-hydroxycarbazepine (MHD) [S-(+)- and R-(-)-MHD] using liquid chromatography with tandem mass spectrometry (LC-MS/MS). Additionally, the free fraction of the drug is described in healthy volunteers (n=12) after the oral administration of 300mg OXC/12h for 5days. Plasma aliquots of 200MUL were submitted to ultrafiltration procedure and 50MUL of the ultrafiltrate were extracted with a mixture of tert-butyl methyl ether:dichloromethane (2:1, v/v). OXC and the MHD enantiomers were separated on a OD-H chiral phase column. The method was linear in the range of 4.0-2.0MUg/mL for OXC and of 20.0-6.0MUg/mL plasma for the MHD enantiomers. The limit of quantification was 4ng for OXC and 20ng for each MHD enantiomer/mL plasma. The intra- and inter-day precision and inaccuracy were less than 15%. The free fraction at the time of peak plasma concentration of OXC was 0.27 for OXC, 0.37 for S-(+)-MHD and 0.42 for R-(-)-MHD. Enantioselectivity in the free fraction of MHD was observed, with a higher proportion of R-(-)-MHD compared to S-(+)-MHD. PMID- 29169111 TI - Identification of phenolic components via LC-MS analysis and biological activities of two Centaurea species: C. drabifolia subsp. drabifolia and C. lycopifolia. AB - The Centaurea genus has great potential in traditional systems and has attracted much interest in the design of novel drug formulations. The present study was focused on the chemical fingerprints and biological properties of Centaurea drabifolia subsp. drabifolia and Centaurea lycopifolia extracts. Spectrophotometric and LC-MS techniques were used to establish the chemical profiles of the studied extracts. Enzyme inhibitory potential was assessed against key enzymes linked to global health problems, namely neurodegenerative diseases (acetylcholinesterase), pigmentation (tyrosinase), and diabetes (alpha amylase and alpha-glucosidase). The antimicrobial propensities of the extract were evaluated against 16 bacterial and fungal strains using the microdilution method. The antioxidant abilities were assessed using DPPH and ABTS radical scavenging, ferric, and cupric reducing powers, phosphomolybdenum, and ferrous metal chelation. The total phenolic compounds varied from 18.33 to 32.84mgGAE/g extract. Total flavonoid content of the extracts were in the range of 2.88 22.39mgRE/g extract. Methanol and water extracts showed stronger antioxidant abilities compared to the ethyl acetate extracts. However, the latter extracts were most efficient towards the target enzymes (except for tyrosinase). The water extracts also exerted considerable antimicrobial effects. Findings from the present work tend to support the idea that C. drabifolia subsp. drabifolia and C. lycopifolia may be utilized as effective bio-resources for designing novel health promoting products or ingredients. It is anticipated that results amassed from this still will open new avenues for research and contribute towards establishing primary data on these species for designing novel phytopharmaceuticals. PMID- 29169113 TI - A rapid and simple HPLC-MS/MS method for the simultaneous quantification of valproic acid and its five metabolites in human plasma and application to study pharmacokinetic interaction in Chinese epilepsy patients. AB - Valproic acid(VPA) is a classic drug that used to treat epilepsy in monotherapy or combination with other anticonvulsant drugs such as lamotrigine (LTG). Although it was reported that VPA could increase lamotrigine trough concentration in clinical practice, there was no report about the effect of LTG on the trough concentration of VPA and its main metabolites, such as 4-ene-VPA, 3-OH-VPA, 4-OH VPA, 3-keto-VPA, 2-PGA which are related to the therapeutic and toxic effects of VPA. In this study, a simple and rapid method for the simultaneous determination of VPA and its five metabolites in human plasma using HPLC-MS/MS was developed for the first time. Benzoic acid was used as an internal standard (IS). Separation was performed on a Hypersil GOLD C18 column by isocratic elution using acetonitrile: 10mM ammonium acetate solution (90:10, v/v) as mobile phase at a flow rate of 0.3mL/min. A triple quadrupole mass spectrometer operating in the negative ion-switching, electron spray ionization mode with selection reaction monitoring (SRM) was employed to determine transitions of m/z 143.183->143.183, 157.033->113.165, 173.017->129.074, 159.058->101.082, 140.870->140. 870, 159.049 >123.076, 121.035->77.136 for VPA, 2-PGA, 3-keto-VPA, 3-OH-VPA, 4-ene-VPA, 4-OH VPA and IS, respectively. The method also afforded satisfactory results in terms of sensitivity, specificity, precision (intra- and inter-batch), accuracy, recovery, matrix effect and stability. This method was successfully applied to evaluate the effect of LTG on the trough concentration of VPA, 2-PGA, 3-keto-VPA, 3-OH-VPA, 4-ene-VPA, 4-OH-VPA in Chinese epilepsy patients. The result showed that there was no significant difference in the concentration of VPA and its five metabolites between patients in VPA monotherapy and patients in therapy combining VPA with LTG. PMID- 29169116 TI - p-Nitrophenol degradation by Fenton's oxidation in a bubble column reactor. AB - This paper reports on a study of the oxidation of p-nitrophenol (PNP) in a bubble column reactor (BCR). The use of the air stream aimed to provide perfect mixing in the liquid phase, which was successfully achieved and checked experimentally; there were no concentration gradients along the column, even at the lowest air flow rate used (Q = 1 mL/min at room temperature and atmospheric pressure). The effect of the operating variables was assessed, and a total reduction of PNP was reached, as well as mineralization of 49.2%, oxidant consumption of 90.3%, and with an efficiency of use - etaH2O2 - of 0.09 mg C/mg H2O2, under the best operating conditions found - Q = 1 mL/min, [H2O2] = 1.6 g/L, [Fe2+] = 80 mg/L, pH = 3.0 and T = 22-24 degrees C - (after 120 min of reaction). Following this, various strategies were developed for improving the mineralization rate; it was found that the addition of H2O2 every 5 min and readjusting the pH after 30 min of reaction allow the attainment of a much higher TOC removal (75.1%) and efficiency of oxidant use (etaH2O2 = 0.17 mg C/mg H2O2) with less oxidant. A reaction mechanism was proposed, based on intermediates identified that include p nitrocatechol - PNC, p-benzoquinone - PB, hydroquinone - HQ - and carboxylic acids (oxalic, maleic and fumaric). Since the performance achieved in the BCR was good, and very similar to that obtained in a conventional batch reactor, it was possible to verify the efficacy of carrying out the Fenton process in this reactor configuration, which in our future work will focus on the treatability of industrial effluents. PMID- 29169114 TI - Evaluation of antiparkinson activity of PTUPB by measuring dopamine and its metabolites in Drosophila melanogaster: LC-MS/MS method development. AB - Soluble epoxide hydrolase (sEH) inhibition is reported to elevate endogenous epoxyeicosatrienoic acids (EET's), which are known to play an important role in neuroprotection by inhibiting oxidative stress and neuroinflammation. In the present study, PTUPB, a dual inhibitor of sEH and COX-2, has been tested for its antiparkinson activity against rotenone (ROT) induced neurodegeneration in Drosophila model of Parkinson's disease (PD). To determine the efficacy and brain bioavailability of PTUPB a simple, rapid and sensitive LC-MS/MS method was developed and validated for the estimation of PTUPB (Method-I), dopamine (DA) and its metabolites (Method-II) in fly head. Mass spectrometric acquisitions of analytes signals were performed in positive and negative electron spray ionization MRM mode by monitoring the daughter ions. The isocratic elution using formic acid (0.1% v/v) and acetonitrile (20:80v/v) (for method I), and acetic acid (0.1% v/v) and methanol (for method II) on Jones C18 was carried out to achieve the separation. The results of brain PTUPB, DA and its metabolites estimation shows a dose dependent increase in PTUPB concentration and a dose dependent prevention of ROT induced changes in DA and its metabolites levels (p<0.05), indicating a significant neuroprotection activity of PTUPB. In the present study, we have successfully developed and validated LC-MS/MS methods to identify and quantify PTUPB, DA and its metabolites using a UFLC-ESI-QqQ mass spectrometer for the screening of neuroprotective agents in Drosophila Melanogaster. PMID- 29169117 TI - 3D correction over 2years with anterior vertebral body growth modulation: A finite element analysis of screw positioning, cable tensioning and postoperative functional activities. AB - BACKGROUND: Anterior vertebral body growth modulation is a fusionless instrumentation to correct scoliosis using growth modulation. The objective was to biomechanically assess effects of cable tensioning, screw positioning and post operative position on tridimensional correction. METHODS: The design of experiments included two variables: cable tensioning (150/200N) and screw positioning (lateral/anterior/triangulated), computationally tested on 10 scoliotic cases using a personalized finite element model to simulate spinal instrumentation, and 2years growth modulation with the device. Dependent variables were: computed Cobb angles, kyphosis, lordosis, axial rotation and stresses exerted on growth plates. Supine functional post-operative position was simulated in addition to the reference standing position to evaluate corresponding growth plate's stresses. FINDINGS: Simulated cable tensioning and screw positioning had a significant impact on immediate and after 2years Cobb angle (between 5 degrees -11 degrees , p<0.01). Anterior screw positioning significantly increased kyphosis after 2years (6 degrees -8 degrees , p=0.02). Triangulated screw positioning did not significantly impact axial rotation but significantly reduced kyphosis (8 degrees -10 degrees , p=0.001). Growth plates' stresses were increased by 23% on the curve's convex side with cable tensioning, while screw positioning rather affected anterior/posterior distributions. Supine position significantly affected stress distributions on the apical vertebra compared to standing position (respectively 72% of compressive stresses on convex side vs 55%). INTERPRETATION: This comparative numerical study showed the biomechanical possibility to adjust the fusionless instrumentation parameters to improve correction in frontal and sagittal planes, but not in the transverse plane. The convex side stresses increase in the supine position may suggest that growth modulation could be accentuated during nighttime. PMID- 29169115 TI - Prolonged oxidative stress down-regulates Early B cell factor 1 with inhibition of its tumor suppressive function against cholangiocarcinoma genesis. AB - Early B cell factor 1 (EBF1) is a transcription factor involved in the differentiation of several stem cell lineages and it is a negative regulator of estrogen receptors. EBF1 is down-regulated in many tumors, and is believed to play suppressive roles in cancer promotion and progression. However, the functional roles of EBF1 in carcinogenesis are unclear. Liver fluke-infection associated cholangiocarcinoma (CCA) is an oxidative stress-driven cancer of bile duct epithelium. In this study, we investigated EBF1 expression in tissues from CCA patients, CCA cell lines (KKU-213, KKU-214 and KKU-156), cholangiocyte (MMNK1) and its oxidative stress-resistant (ox-MMNK1-L) cell lines. The formation of 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) was used as an oxidative stress marker. Our results revealed that EBF1 expression was suppressed in cancer cells compared with the individual normal bile duct cells at tumor adjacent areas of CCA tissues. CCA patients with low EBF1 expression and high formation of 8-oxodG were shown to correlate with poor survival. Moreover, EBF1 was suppressed in the oxidative stress-resistant cell line and all of CCA cell lines compared to the cholangiocyte cell line. This suggests that prolonged oxidative stress suppressed EBF1 expression and the reduced EBF1 level may facilitate CCA genesis. To elucidate the significance of EBF1 suppression in CCA genesis, EBF1 expression of the MMNK1 cell line was down-regulated by siRNA technique, and its effects on stem cell properties (CD133 and Oct3/4 expressions), tumorigenic properties (cell proliferation, wound healing and cell migration), estrogen responsive gene (TFF1), estrogen-stimulated wound healing, and cell migration were examined. The results showed that CD133, Oct3/4 and TFF1 expression levels, wound healing, and cell migration of EBF1 knockdown-MMNK1 cells were significantly increased. Also, cell migration of EBF1-knockdown cells was significantly enhanced after 17beta estradiol treatment. Our findings suggest that EBF1 down-regulation via oxidative stress induces stem cell properties, tumorigenic properties and estrogen responses of cholangiocytes leading to CCA genesis with aggressive clinical outcomes. PMID- 29169118 TI - Characterization of a microbial polysaccharide-based bioflocculant and its anti inflammatory and pro-coagulant activity. AB - We describe a novel bioflocculant, MBF-15, which is an exopolysaccharide extracted from the alkaliphilic bacterium Paenibacillus jamilae. The biophysical characteristics of MBF-15 were determined using Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. MBF-15 was also evaluated for its biocompatibility by examining its inflammatory, coagulant, and hemostatic properties in vitro and in vivo. Pretreatment of peripheral blood mononuclear cells with MBF-15 inhibited lipopolysaccharide-stimulated expression of inducible nitric oxide synthase, production of nitric oxide, and secretion of pro inflammatory cytokines, including tumor necrosis factor-alpha and interleukin-6. In addition, MBF-15 increased both mRNA and protein levels of the anti inflammatory cytokines transforming growth factor-beta and IL-10. The hemocompatibility of MBF-15 was investigated by measuring the hemolysis ratio and clotting times. MBF-15 had high pro-thrombogenic activity but was not hemolytic. In a rat model, MBF-15 showed superior hemostatic properties compared with chitosan. Thus, MBF-15 offers a promising combination of anti-inflammatory and pro-coagulant properties that may be useful for hemostasis in a variety of clinical settings. PMID- 29169119 TI - OBP fused with cell-penetrating peptides promotes liposomal transduction. AB - Cell-penetrating peptides (CPPs) have been applied as novel transport systems with the ability to facilitate the delivery of peptides, proteins, and oligonucleotides into cells. Herein, we designed different fusion proteins composed by pig odorant binding protein (OBP-I) and three CPPs, namely Tat, pVEC and Pep-1. A new methodology using liposomes as reservoirs and OBP:CPPs as carriers was developed as an advanced system to capture odorant molecules. 1 aminoanthracene (1-AMA) was used as a model molecule to evaluate the transduction ability of OBP:CPPs into the reservoirs. The transduction efficiency was dependent on the initial capacity of OBP:CPPs to bind 1-AMA and on the penetration of liposomes promoted by the CPPs. An encapsulation efficiency of 42% was obtained with OBP:Tat fusion protein. The presence of Tat peptide increased the 1-AMA transduction of 1.3 and 2.5 fold compared with Pep-1 and pVEC, respectively. This work expands the application of OBPs and CPPs on the design of promising capture and delivery systems for textile and cosmetic applications. PMID- 29169120 TI - Soybean peroxidase immobilized onto silica-coated superparamagnetic iron oxide nanoparticles: Effect of silica layer on the enzymatic activity. AB - Peroxidase immobilization onto magnetic supports is considered an innovative strategy for the development of technologies that involves enzymes in wastewater treatment. In this work, magnetic biocatalysts were prepared by immobilization of soybean peroxidase (SBP) onto different silica-coated superparamagnetic iron oxide nanoparticles. The obtained magnetic biocatalysts were tested for the degradation of malachite green (MG), a pollutant often found in industrial wastewaters and with significant drawbacks for the human and environmental health. A deep physicochemical characterization of the materials was performed by means of X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), High Resolution-Transmission Electron Microscope (HR-TEM) and magnetization measurements among others techniques. Results showed high immobilization yield of SBP onto nanomaterials with excellent properties for magnetic recoverability. A partial loss of activity with respect to free SBP was observed, compatible with the modification of the conformational structure of the enzyme after immobilization. The structural modification depended on the amount (and thickness) of silica present in the hybrid materials and the activity yield of 43% was obtained for the best biocatalyst. Thermal stability and reusability capacity were also evaluated. PMID- 29169121 TI - Perceptions of firearms and suicide: The role of misinformation in storage practices and openness to means safety measures. AB - BACKGROUND: Firearm ownership and unsafe storage increase risk for suicide. Little is known regarding factors that influence storage practices and willingness to engage in means safety. METHODS: Utilizing Amazon's Mechanical Turk program, we recruited an online sample of 300 adults living in the US who own at least one firearm. Firearm storage practices and openness to means safety measures were assessed using items designed for this study. Data were collected and analyzed in 2017. RESULTS: Firearms stored in non-secure locations and without a locking device were associated with lower beliefs in the relationship between firearm storage and suicide risk. Fearlessness about death moderated the association between current secure versus non-secure storage and beliefs regarding firearm storage and suicide risk, in that storage practices and beliefs were more strongly related at higher levels of fearlessness about death. For both secure and locked storage of a firearm, there was a significant indirect effect of current storage practices on willingness to engage in means safety in the future through current beliefs regarding the relationship between firearm storage and suicide risk. Unsafe storage practices were largely associated with an unwillingness to store firearms more safely or to allow a trusted peer to temporarily store the firearm outside the home in order to prevent their own or someone else's suicide. LIMITATIONS: Self-report and cross-sectional data were used. Results may not generalize to non-firearm owners. CONCLUSIONS: Firearm owners are prone to inaccurate beliefs about the relationship between firearms and suicide. These beliefs may influence both current firearm storage practices and the willingness to engage in means safety. PMID- 29169122 TI - PTSD with and without dissociation in young children exposed to interpersonal trauma. AB - BACKGROUND: A Dissociative Subtype of Posttraumatic Stress Disorder (PTSD) was added to the DSM-5, but little is known about this symptom pattern in young children exposed to trauma. Tailoring treatment to traumatized young children requires understanding the different patterns of trauma-related symptomatology and important correlates. The current study tested the hypothesis that type and number of child traumatic events, caregiver trauma exposure, and caregiver symptomatology would predict whether traumatized young children presented with PTSD, PTSD with clinical dissociation, or non-clinical trauma symptoms. METHODS: A multinomial regression was conducted using data collected from an ethnically and economically diverse sample of 297 trauma-exposed children between the ages of 3 and 6 and their caregivers. Based on parent-report on a well-validated measure of trauma symptoms, children were categorized into three groups: non clinical (n = 128), PTSD only (n = 104), or PTSD with dissociation (PTSD-DISS; n = 65). Predictors included trauma exposure, parent trauma symptoms, and child sex. RESULTS: Girls were twice more likely than boys to be in the PTSD-DISS group; sexually abused children were almost three times as likely to be in the PTSD-DISS group; and, for every unit increase in parent avoidance symptoms or number of traumatic events, the odds of being in the PTSD-DISS group increased significantly. LIMITATIONS: Given the cross-sectional study design, conclusions cannot be drawn regarding causality. Measures were completed by a single reporter. CONCLUSIONS: Findings suggest that subgroups of children may be especially vulnerable to comorbid PTSD and dissociation. Implications for treatment are discussed. PMID- 29169123 TI - The comparative effectiveness of electroencephalographic indices in predicting response to escitalopram therapy in depression: A pilot study. AB - BACKGROUND: This study aims to compare the effectiveness of EEG frequency band activity including interhemispheric asymmetry and prefrontal theta cordance in predicting response to escitalopram therapy at 8-weeks post-treatment, in a multi site initiative. METHODS: Resting state 64-channel EEG data were recorded from 44 patients with a diagnosis of major depressive disorder (MDD) as part of a larger, multisite discovery study of biomarkers in antidepressant treatment response, conducted by the Canadian Biomarker Integration Network in Depression (CAN-BIND). Clinical response was measured at 8-weeks post-treatment as change from baseline Montgomery-Asberg Depression Rating Scale (MADRS) score of 50% or more. EEG measures were analyzed at (1) pre-treatment baseline (2) 2 weeks post-treatment and (3) as an ''early change" variable defined as change in EEG from baseline to 2 weeks post-treatment. RESULTS: At baseline, treatment responders showed elevated absolute alpha power in the left hemisphere while non-responders showed the opposite. Responders further exhibited a cortical asymmetry in the parietal region. Groups also differed in pre-treatment relative delta power with responders showing greater power in the right hemisphere over the left while non responders showed the opposite. At 2 weeks post-treatment, responders exhibited greater absolute beta power in the left hemisphere relative to the right and the opposite was noted for non-responders. A reverse pattern was noted for absolute and relative delta power at 2 weeks post-treatment. Responders exhibited early reductions in relative alpha power and early increments in relative theta power. Non-responders showed a significant early increase in prefrontal theta cordance. CONCLUSIONS: Hemispheric asymmetries in the alpha and delta bands at baseline and at 2 weeks post-treatment have moderately strong predictive utility in predicting response to antidepressant treatment. PMID- 29169124 TI - Dorsomedial frontal cortical metabolic differences of comorbid generalized anxiety disorder in refractory major depression: A [18F] FDG PET brain imaging study. AB - BACKGROUND: Refractory major depressive disorder (MDD) is a severe mental disorder, chronic and difficult to treat. Although generalized anxiety disorder (GAD) is frequently observed as a comorbid diagnosis, little is known on the comorbid neurobiological substrate. Better insights may improve adequate treatment algorithms. OBJECTIVE: To examine this poorly understood clinical question, we recruited 52 individuals to participate in a [18F] FDG PET brain imaging study. METHODS: Twenty-two refractory MDD patients were diagnosed with and 15 refractory MDD patients without comorbid GAD. To compare to the none depressed state a sample of 15 age and gender matched never-depressed individuals were included. RESULTS: Compared to healthy control subjects, all patients showed significantly higher metabolic activity in the bilateral parahippocampal areas. Compared to MDD patients, healthy subjects displayed significant higher metabolic activity in distinct (bi)frontotemporal and parietal cortices. Refractory MDD patients without comorbid GAD showed significant higher metabolic activity in the dorsomedial parts of the frontal cortex (dmFC). CONCLUSIONS: The impaired dmFC metabolic activity observed in comorbid GAD within refractory MDD may be indicative of specific emotional dysfunctional top-down processing in this subgroup, conform the anxiety state. Additional psychotherapeutic interventions may be warranted. PMID- 29169125 TI - Functional connectivity between salience, default mode and frontoparietal networks in post-stroke depression. AB - BACKGROUND: Previous studies have demonstrated altered resting state functional connectivity (rsFC) in patients with post-stroke depression (PSD). It remains unclear whether rsFC is changed at the network level as was shown for major depressive disorder (MDD). To address this question, we investigated rsFC of resting sate networks (RSNs) in PSD. METHODS: Eleven subjects with PSD underwent fMRI scanning at rest before and after treatment. The severity of depression was assessed using the aphasic depression rating scale (ADRS). We performed functional network connectivity (FNC) analysis for RSNs, region of interest - FC analysis (ROI-FC) and calculation of brain matter volumes in ROIs overlapping with RSNs and in other brain regions associated with mood maintenance. RESULTS: We found positive correlation of FNC between anterior default mode network (aDMN) and salience network (SAL) with depression severity before treatment, the latter accompanied by the increase of white matter in the middle frontal and left angular gyri. FNC of aDMN and left frontoparietal network (LFP) decreased after treatment. ROI-FC and the brain matter volumes of several regions of DMN, LFP and SAL also showed a correlation with ADRS or significant change after treatment. LIMITATIONS: Limitations include small sample size and methodological issues concerning altered hemodynamics in stroke. However, we took complex preprocessing steps to overcome these issues. CONCLUSION: Present results of altered rsFC in PSD are consistent with previous findings in MDD. The convergence of results obtained in PSD and MDD supports the validity of rsFC approach for investigation of brain network dysfunctions underling these psychiatric symptoms. PMID- 29169126 TI - Effect of copper on the translocation and transformation of polychlorinated biphenyls in rice. AB - Contamination of organic pollutants in the environment is usually accompanied by heavy metals. However, a little information on the influences of heavy metals on the uptake, translocation and transformation of organic pollutants in plants is available. In this study, ten-day hydroponic exposure was conducted to explore the influence of copper (Cu) on the bioaccumulation and biotransformation of polychlorinated biphenyls (PCBs) in intact young rice (Oryza sativa L.). Low dose of Cu (<=100 MUmol/L) increased the accumulation of CB-61 in rice plants, while excess concentrations of Cu (>100 MUmol/L) inhibited uptake and translocation of CB-61. Effect of Cu on the uptake of CB-61 was attributed to the Cu-triggered damage to the roots of rice plants. The presence of a moderate dose of Cu (50 MUmol/L) enhanced the formation of hydroxylated polychlorinated biphenyls (OH PCBs) and methoxylated polychlorinated biphenyls (MeO-PCBs), whereas excess concentrations of Cu (250 MUmol/L) inhibited the metabolism of CB-61. The effect of Cu on the interconversion between 4'-OH-CB-61 and 4'-MeO-CB-61 was also concentration dependent: the biotransformation was promoted by a moderate concentration of Cu but inhibited by excess concentrations of Cu. The activities of Cytochrome P450 (CYP450) and S-adenosyl-l-methionine (SAM)-dependent methyltransferase in the roots of rice plants exposed to Cu and CB-61 or its derivatives were consistent with the pattern and trend of the metabolites observed in rice roots. These results could provide valuable insights into the interactions and combined effects of PCBs and heavy metals in plants. PMID- 29169127 TI - A decision support tool for selecting the optimal sewage sludge treatment. AB - Sewage sludge contains significant amounts of resources, such as nutrients and organic matter. At the same time, the organic contaminants (OC) found in sewage sludge are of growing concern. Consequently, in many European countries incineration is currently favored over recycling in agriculture. This study presents a Multi-Attribute Value Theory (MAVT)-based decision support tool (DST) for facilitating sludge treatment decisions. Essential decision criteria were recognized and prioritized, i.e., weighted, by experts from water utilities. Since the fate of organic contaminants was in focus, a simple scoring method was developed to take into account their environmental risks. The final DST assigns each sludge treatment method a preference score expressing its superiority compared to alternative methods. The DST was validated by testing it with data from two Finnish municipal wastewater treatment plants (WWTP). The validation results of the first case study preferred sludge pyrolysis (preference score: 0.629) to other alternatives: composting and incineration (score 0.580, and 0.484 respectively). The preference scores were influenced by WWTP dependent factors, i.e., the operating environment and the weighting of the criteria. A lack of data emerged as the main practical limitation. Therefore, not all of the relevant criteria could be included in the value tree. More data are needed on the effects of treatment methods on the availability of nutrients, the quality of organic matter and sludge-borne OCs. Despite these shortcomings, the DST proved useful and adaptable in decision-making. It can also help achieve a more transparent, understandable and comprehensive decision-making process. PMID- 29169128 TI - Sample handling and data processing for fluorescent excitation-emission matrix (EEM) of dissolved organic matter (DOM). AB - In environmental engineering and science, fluorescent excitation-emission matrix (EEM) has increasingly been utilized to characterize chromophoric dissolved organic matter (CDOM). This study aims to delineate EEM data processing, including calculation of total fluorescence (TF) which is an emerging water quality parameter often used as a surrogate for micropollutant removal by advanced water treatment processes. In addition, sample handling procedures such as storage, use of preservatives, and oxidant quenching agents were evaluated. In this study, three antimicrobial preservatives were tested: sodium azide, sodium omadine, and thymol. All the tested preservatives altered optical properties of samples, and were therefore not suitable for the preservation of EEM samples. Without preservative, storage of samples at 4 degrees C maintained TF within 7.5% of its original value for 21 days, while TF of samples stored at the room temperature more drastically changed (up to 15%). The impacts of three oxidant quenching agents including ascorbic acid, sodium bisulfite, and sodium thiosulfate on EEM were also tested. Among the quenching agents, sodium bisulfite was found to be suitable since it little influenced optical properties of samples while the other two were not favorable due to interference. We also scrutinized the use of TF as surrogate to monitor micropollutant rejection by nanofiltration membrane. PMID- 29169129 TI - Saline soil properties, quality and productivity of wheat grown with bagasse ash and thiourea in different climatic zones. AB - Soil salinity and atmosphere temperature change have negative impacts on crop productivity and its quality and can pose a significant risk to soil properties in semi-arid regions. We conducted two field experiments in North (first zone) and South (second zone) of Egypt to investigate the effects of soil bagasse ash (10 ton ha-1), foliar thiourea (240 g ha-1) and their combination in comparison to the control treatment on saline soil properties and productivity and quality traits of wheat. All studied treatments were received the recommended rate of N, P and K fertilizations. Combination of soil bagasse ash and foliar thiourea application resulted in a significant improvement of most studied soil properties (i.e. EC, compaction, hydraulic conductivity, OM and available P, K, N contents) after harvest in comparison to other treatments in both of zones. Also, it enhanced growth and grain yield of wheat in terms of photosynthesis related attributes and yield components. Moreover, combination of soil bagasse ash and foliar thiourea application resulted in superior grain quality traits in terms of carbohydrate, fibre, protein and ash contents than separated application of soil bagasse ash, foliar thiourea or even control treatment. In conclusion, combination of soil bagasse ash and foliar thiourea application can be used as suitable option to enhance plant nutrition, wheat productivity and improve wheat grain quality and soil traits in saline soil as well as can alleviate heat stress. PMID- 29169131 TI - Occurrence of benzothiazole, benzotriazole and benzenesulfonamide derivates in outdoor air particulate matter samples and human exposure assessment. AB - Benzothiazole (BTHs), benzotriazole (BTRs) and benzenesulfonamide (BSAs) derivates are high production volume chemicals and they are used in several industrial and household applications, therefore it is expected their occurrence in various environments, especially water and air. In this study we developed a method based on gas chromatography-mass spectrometry (GC-MS) combined with pressurised liquid extraction (PLE) to simultaneously determine four BTR, five BTH and six BSA derivates in the particulate matter (PM10) of outdoor air samples collected in quartz fibre filters (QFFs). To the best of our knowledge, this is the first time these compounds have been determined in open ambient environments. Under optimised conditions, method recoveries at the lower and upper concentration levels (0.8 and 4.2 ng m-3) ranged from 70 to 120%, except for 1-H benzothiazole and 2-chlorobenzothiazole, which were about 50%. The repeatability of the method was usually below 20% (n = 3, %RSD) for both concentration levels. This method enables the contaminants to be detected at pg m-3 concentration levels. Several samples from two different sites influenced by local industries showed that BTRs, followed by BTHs, were the most detected compounds, whereas BSAs were hardly found. The most frequently determined compounds were 1-H benzothiazole, 2-chlorobenzothiazole, 1-H-benzotriazole, 2-hydroxibenzothiazole, 5,6-dimethyl-1-H-benzotriazole and the isomers 4- and 5-methyl-1-H-benzotriazole. With the concentrations found, the human exposure assessment and health risk characterization via ambient inhalation were also evaluated taking into account different subpopulation groups classified by age for the two sampling points. PMID- 29169130 TI - Can liming reduce cadmium (Cd) accumulation in rice (Oryza sativa) in slightly acidic soils? A contradictory dynamic equilibrium between Cd uptake capacity of roots and Cd immobilisation in soils. AB - Cadmium (Cd) accumulation in rice is strongly controlled by liming, but information on the use of liming to control Cd accumulation in rice grown in slightly acidic soils is inconsistent. Here, pot experiments were carried out to investigate the mechanisms of liming on Cd accumulation in two rice varieties focusing on two aspects: available/exchangeable Cd content in soils that were highly responsive to liming, and Cd uptake and transport capacity in the roots of rice in terms of Cd accumulation-relative gene expression. The results showed that soil availability and exchangeable iron, manganese, zinc and Cd contents decreased with increased liming, and that genes related to Cd uptake (OsNramp5 and OsIRT1) were sharply up-regulated in the roots of the two rice varieties. Thus, iron, manganese, zinc and Cd contents in rice plants increased under low liming applications but decreased in response to high liming applications. However, yield and rice quantities were only slightly affected. These results indicated that Cd accumulation in rice grown in slightly acidic soils presents a contradictory dynamic equilibrium between Cd uptake capacity by roots and soil Cd immobilisation in response to liming. The enhanced Cd uptake capacity under low liming dosages increases risks to human health. PMID- 29169132 TI - Comparative evaluation of sorption kinetics and isotherms of pyrene onto microplastics. AB - Concerns regarding microplastics pollution and their potential to concentrate and transport organic contaminants in aquatic environments are growing in recent years. Sorption of organic chemicals by microplastics may affect the distribution and bioavailability of the chemicals. Here sorption process of pyrene (Pyr), a frequently encountered polycyclic aromatic hydrocarbon in aquatic environments, on three types of mass-produced plastic particles (high-density polyethylene (PE), polystyrene (PS) and polyvinylchloride (PVC)), was investigated by comparative analysis of different sorption kinetic and isotherm models. Optimum kinetic and isotherm models were predicted by the linear least-squares regression method. The pseudo-second-order kinetic model was more appropriate in describing the entire sorption process (R2 > 0.99). Sorption rates of Pyr onto microplastics were mainly controlled by intraparticle diffusion. PE exhibited the highest affinity for Pyr, followed by PS and PVC. The sorption equilibrium data were best fitted to the Langmuir isotherm (R2 > 0.99), indicating monolayer coverage of Pyr onto the microplastics. PMID- 29169133 TI - Alterations of mitochondrial antioxidant indexes and apoptosis in duck livers caused by Molybdenum or/and cadmium. AB - Cadmium (Cd) and high Molybdenum (Mo) can lead to adverse reactions on animals, but the co-induced toxicity of Mo and Cd to liver in ducks was not well understood. To investigate the co-induced toxic effects of Mo combined with Cd on mitochondrial oxidative stress and apoptosis in duck livers. 240 healthy 11-day old ducks were randomly divided into 6 groups (control, LMo group, HMo group, Cd group, LMoCd group and HMoCd group). After being treated for 30, 60, 90 and 120 days, liver mitochondrial antioxidant indexes, ceruloplasmin (CP), metallothionein (MT), Bak-1 and Caspase-3 genes mRNA expression levels, and ultrastructural changes were evaluated. The results showed that total antioxidative capacity (T-AOC), catalase (CAT), superoxide dismutase (SOD) and xanthine oxidase (XOD) activities in experimental groups were decreased, whereas malondialdehyde (MDA) content and nitric oxide synthase (NOS) activity were increased compared with control group, and these changes of co-treated groups were more obvious in the later period of the experiment. The mRNA expression levels of CP, Bak-1 and Caspase-3 were up-regulated in experimental groups compared with control group and showed significant difference between co-treated groups and single treated groups. The mRNA expression level of MT in Cd group was higher than that in co-treated groups. Additionally, ultrastructural changes showed karyopyknosis, mitochondrial swelling, vacuolation and disruption of mitochondrial cristae in co-treated groups. Taken together, it was suggested that dietary Mo and Cd might lead to mitochondrial oxidative stress and apoptosis in duck livers, and it showed a possible synergistic relationship between the two elements. PMID- 29169134 TI - The comparison of greenhouse gas emissions in sewage treatment plants with different treatment processes. AB - Greenhouse gas emissions from different sewage treatment plants: oxidation ditch process, double-circulated anoxic-oxic process and anoxic-oxic process were evaluated based on the survey. The methane and nitrous oxide characteristics were discussed based on the gaseous and dissolved gas profiles. As a result, it was found that methane was produced in the sewer pipes and the primary sedimentation tank. Additionally, a ventilation system would promote the gasification of dissolved methane in the first treatment units. Nitrous oxide was produced and emitted in oxic tanks with nitrite accumulation inside the sewage treatment plant. A certain amount of nitrous oxide was also discharged as dissolved gas through the effluent water. If the amount of dissolved nitrous oxide discharge is not included, 7-14% of total nitrous oxide emission would be overlooked. Based on the greenhouse gas calculation, electrical consumption and the N2O emission from incineration process were major sources in all the plants. For greenhouse gas reduction, oxidation ditch process has an advantage over the other advanced systems due to lower energy consumption, sludge production, and nitrogen removal without gas stripping. PMID- 29169135 TI - Nitrogen removal capacity and bacterial community dynamics of a Canon biofilter system at different organic matter concentrations. AB - Three Canon bench-scale bioreactors with a volume of 2 L operating in parallel were configured as submerged biofilters. In the present study we investigated the effects of a high ammonium concentration (320 mgNH4+. L-1) and different concentrations of organic matter (0, 100 and 400 mgCOD.L-1) on the nitrogen removal capacity and the bacterial community structure. After 60 days, the Canon biofilters operated properly under concentrations of 0 and 100 mgCOD.L-1 of organic matter, with nitrogen removal efficiencies up to 85%. However, a higher concentration of organic matter (400 mgCOD.L-1) produced a partial inhibition of nitrogen removal (68.1% efficiency). The addition of higher concentrations of organic matter a modified the bacterial community structure in the Canon biofilter, increasing the proliferation of heterotrophic bacteria related to the genera of Thauera, Longilinea, Ornatilinea, Thermomarinilinea, unclassified Chlorobiales and Denitratisoma. However, heterotrophic bacteria co-exist with Nitrosomonas and Candidatus Scalindua. Thus, our study confirms the co-existence of different microbial activities (AOB, Anammox and denitrification) and the adaptation of a fixed-biofilm system to different concentrations of organic matter. PMID- 29169136 TI - Degradation of diethyl phthalate (DEP) by UV/persulfate: An experiment and simulation study of contributions by hydroxyl and sulfate radicals. AB - Degradation of diethyl phthalate (DEP) by ultraviolet/persulfate (UV/PS) process at different reaction conditions was evaluated. DEP can be degraded effectively via this process. Both tert-butyl (TBA) and methanol (MeOH) inhibited the degradation of DEP with MeOH having a stronger impact than TBA, suggesting sulfate radical () and hydroxyl radical (HO) both existed in the reaction systems studied. The second-order rate constants of DEP reacting with and HO were calculated to be (6.4+/-0.3)*107 M-1s-1 and (3.7+/-0.1)*109 M-1s-1, respectively. To further access the potential degradation mechanism in this system, the pseudo first-order rate constants (ko) and the radical contributions were modeled using a simple steady-state kinetic model involving and HO. Generally, HO had a greater contribution to DEP degradation than . The ko of DEP increased as PS dosages increased when PS dosages were below 1.9 mM. However, it decreased with increasing initial DEP concentrations, which might be due to the radical scavenging effect of DEP. The ko values in acidic conditions were higher than those in alkaline solutions, which was probably caused by the increasing concentration of hydrogen phosphate (with higher scavenging effects than dihydrogen phosphate) from the phosphate buffer as pH values rose. Natural organic matter and bicarbonate dramatically suppressed the degradation of DEP by scavenging and HO. Additionally, the presence of chloride ion (Cl-) promoted the degradation of DEP at low Cl- concentrations (0.25-1 mM). Finally, the proposed degradation pathways were illustrated. PMID- 29169137 TI - Characterization and mechanism analysis of lincomycin biodegradation with Clostridium sp. strain LCM-B isolated from lincomycin mycelial residue (LMR). AB - Lincomycin mycelial residue (LMR) is the restricted resource because it contains residual lincomycin, which is producing potential risks to the environment and human health. In this study, lincomycin-degrading strain LCM-B was isolated and identified as Clostridium sp. in the LMR. Strain LCM-B was able to degrade 62.03% of lincomycin at the initial concentration of 100 mg L-1 after incubation for 10 d, while only 15.61% of lincomycin was removed at the initial concentration of 500 mg L-1. The removal efficiency of lincomycin by strain LCM-B decreased as the initial concentration increased. Gene lnuB (which encodes the nucleotidyl transferase) was detected in the isolated strain, and it was proven to participate in lincomycin biodegradation based on the analysis of degradation products and pathway. The results provide a relatively complete understanding of lincomycin biodegradation mechanism. Strain LCM-B is promising to eliminate lincomycin from the LMR. PMID- 29169138 TI - In situ fabrication of green reduced graphene-based biocompatible anode for efficient energy recycle. AB - Improving the anode configuration to enhance biocompatibility and accelerate electron shuttling is critical for efficient energy recovery in microbial fuel cells (MFCs). In this paper, green reduced graphene nanocomposite was successfully coated using layer-by-layer assembly technique onto carbon brush anode. The modified anode achieved a 3.2-fold higher power density of 33.7 W m-3 at a current density of 69.4 A m-3 with a 75% shorter start period. As revealed in the characterization, the green synthesized nanocomposite film affords larger surface roughness for microbial colonization. Besides, gold nanoparticles, which anchored on graphene sheets, promise the relatively high electroactive sites and facilitate electron transfer from electricigens to the anode. The reduction oxidation peaks in cyclic voltammograms indicated the mechanism of surface cytochromes facilitated current generation while the electrochemical impedance spectroscopy confirmed the enhanced electron transfer from surface cytochrome to electrode. The green synthesis process has the potential to generate a high performing anode in further applications of MFCs. PMID- 29169139 TI - Analysis of extracellular polymeric substances (EPS) and ciprofloxacin-degrading microbial community in the combined Fe-C micro-electrolysis-UBAF process for the elimination of high-level ciprofloxacin. AB - Extracellular polymeric substances (EPS) and ciprofloxacin-degrading microbial community in the combined Fe-C micro-electrolysis and up-flow biological aerated filter (UBAF) process for the treatment of high-level ciprofloxacin (CIP) were analyzed. The research demonstrated a great potential of Fe-C micro-electrolysis UBAF for the elimination of high-level CIP. Above 90% of CIP removal was achieved through the combined process at 100 mg L-1 of CIP loading. In UBAF, the pollutants were mainly removed at 0-70 cm heights. Three-dimensional fluorescence spectrum (3D-EEM) was used to characterize the chemical structural of loosely bound EPS (LB-EPS) and tightly bound EPS (TB-EPS) extracted from biofilm sample in UBAF. The results showed that the protein-like substances in LB-EPS and TB-EPS had no clear change in the study. Nevertheless, an obvious release of polysaccharides in EPSs was observed during long-term exposure to CIP, which was considered as a protective response of microbial to CIP toxic. The high throughput sequencing results revealed that the biodiversity of bacteria community became increasingly rich with gradual ciprofloxacin biodegradation in UBAF. The ciprofloxacin-degrading microbial community was mainly dominated by Proteobacteria and Bacteroidetes. Microorganisms from genera Dechloromonas, Brevundimonas, Flavobacterium, Sphingopyxis and Bosea might take a major role in ciprofloxacin degradation. This study provides deep theoretical guidance for real CIP wastewater treatment. PMID- 29169141 TI - Complicated grief and caregiving correlates among bereaved adolescent girls in South Africa. AB - To our knowledge, this is the first study to document correlates of complicated grief among bereaved adolescents in sub-Saharan Africa. Participants included 339 female adolescents in South Africa who experienced the loss of a loved one at least six months prior to the survey; their primary caregivers were also surveyed. One-fifth of adolescents were classified as having complicated grief using the Inventory of Complicated Grief Revised for Children in conjunction with grief-induced functional impairment. The loss of a biological parent, the primary caregiver's level of grief, and economic stressors since the loss were associated with increased odds of complicated grief among adolescents. Adolescents' age, residential changes, time since the loss, multiple losses, bereavement due to death by illness, and caregiver depression did not affect the odds. Findings signal the potential of family-centered interventions and economic support services for bereaved adolescents. PMID- 29169140 TI - Facile green synthesis of zinc oxide nanoparticles using Ulva lactuca seaweed extract and evaluation of their photocatalytic, antibiofilm and insecticidal activity. AB - The bioactivity of semiconductor nanocomplexes has been poorly studied in the field of pesticide science. In this research, the synthesis of zinc nanoparticles was accomplished through new effortless green chemistry process, using the Ulva lactuca seaweed extract as a reducing and capping agent. The production of U. lactuca-fabricated ZnO nanoparticles (Ul-ZnO Nps) was characterized by powder X ray diffraction (XRD), UV-visible, Fourier transform infrared (FTIR) spectroscopy, selected area electron diffraction (SAED) analysis and transmission electron microscopy (TEM). The U. lactuca-fabricated ZnO NPs were tested for their photodegradative action against organic dyes, as well as for antibiofilm and larvicidal activities. The UV visible absorbance spectrum of Ul-ZnO NPs exhibited the absorbance band at 325nm and TEM highlighted average crystallite sizes of nanoparticles of 10-50nm. Methylene blue (MB) dye was efficiently corrupted under sunlight in presence of Ul-ZnO NPs. Excellent bactericidal activity was shown by the Ul-ZnO Nps on Gram positive (Bacillus licheniformis and Bacillus pumilis) and Gram negative (Escherichia coliand Proteus vulgaris) bacteria. High antibiofilm potential was noted under both dark and sunlight conditions. The impact of a single treatment with Ul-ZnO NPs on biofilm architecture was also analyzed by confocal laser scanning microscopy (CLSM) on both Gram positive and Gram negative bacteria. Moreover, Ul-ZnO NPs led to 100% mortality of Aedes aegypti fourth instar larvae at the concentration of 50MUg/ml within 24h. The effects of ZnO nanoparticle-based treatment on mosquito larval morphology and histology were monitored. Overall, based on our results, we believe that the synthesis of multifunctional Ul-ZnO Nps using widely available seaweed products can be promoted as a potential eco-friendly option to chemical methods currently used for nanosynthesis of antimicrobials and insecticides. PMID- 29169142 TI - A matter of fact? Adolescents' assumptions about crime, laws, and authority and their domain-specific beliefs about punishment. AB - This study examined adolescents' beliefs about the amount of punishment individuals should receive for violating different laws and whether these beliefs are connected with their informational assumptions (i.e., perceived facts) about crime, laws, and authority. American adolescents (N = 340; Mage = 16.64, 58.2% female) reported their judgments concerning the appropriate punishment for violating laws regulating domain-specific behaviors and their informational assumptions regarding the prevalence and causes of crime, beliefs that authority is knowledgeable, and the purpose of punishment. Greater internal attributions for crime was associated with stronger punishment judgments for violating laws that regulate moral and conventional issues. Greater beliefs that punishment teaches right from wrong was associated with stronger punishment judgments for violating laws that regulate drug-related prudential issues, and lower punishment judgments for violating laws that regulate personal issues. Greater beliefs that authorities are more knowledgeable than others was associated with stronger punishment judgments for violating laws that regulate personal issues. PMID- 29169143 TI - Energy dissipation mapping of cancer cells. AB - The purpose of this study is to map the energy dissipation of Jurkat cells using a single 60 nanosecond pulse electric field (NsPEF), primarily through atomic force microscopy (AFM). The phase shift is generated by the sample elements that do not have a heterogeneous surface. Monitoring and manipulating the phase shift is a powerful way for determining the dissipated energy and plotting the topography. The dissipated energy is a relative value, so the silica wafer and cover slip are given a set reference while the transmission of energy between the tip of the cantilever and cell surfaces is measured. The most important finding is that the magnitude and the number of variations in the dissipated energy change with the strength of NsPEF applied. Utilizing a single low field strength NsPEF (15kV/cm), minor changes in dissipated energy were found. The application of a single high field strength NsPEF (60kV/cm) to Jurkat cells resulted in a higher dissipated energy change versus that of in the low field strength condition. Thus, the dissipated energy from the Jurkat cells changes with the strength of NsPEF. By analyzing the forces via investigation in the tapping mode of the AFM, the stabilization of the cytoskeleton and membrane of the cell are related to the strength of NsPEF applied. Furthermore, the strength of NsPEF indicates a meaningful relationship to the survival of the Jurkat cells. PMID- 29169145 TI - Early results on canine fetal kidney development: Ultrasonographic evaluation and value in prediction of delivery time. AB - To date there have been no studies that describe the ultrasonographic evaluation of kidney development in canine fetuses. The aim of this prospective and longitudinal study was to monitor fetal kidney development with ultrasound and use fetal kidney measurements as a complementary biometric index for estimation of gestational age. Ultrasonographic examinations were performed on 15 clinically healthy pregnant bitches every four days from 30th day of pregnancy, until visualization of the fetal renal pelvis was no longer possible. Four distinct periods of ultrasonographic canine fetal kidney development were defined. Kidney length and renal pelvis distention were measured on longitudinal plane images. The fetal kidney ranged from 0.40 cm to 2.30 cm in length, and diameter of the pelvis ranged from 0.06 cm to 0.17 cm, however by the end of gestation the renal pelvis was no longer dilated and so its diameter could not be measured. Statistical analysis confirmed a relationship between gestational age and fetal kidney growth. Ultrasonographic evaluation of fetal kidney development is simple to perform. There is a strong correlation between gestational age and kidney length, which allowed generation of an equation to estimate delivery date with high sensitivity between 48 and 52 days of pregnancy. Fetal organ development can be considered complete when the renal pelvis is no longer dilated, this finding can assist the ultrasonographer in staging the gestation by prompting examination for fetal intestinal motility which begins at the same gestational age. Measurement of fetal kidney length can be used in conjunction with other methods to estimate gestational age and predict delivery time. PMID- 29169144 TI - Targeting the Wnt/beta-catenin pathway in cancer: Update on effectors and inhibitors. AB - The Wnt/beta-catenin pathway is a family of proteins that is implicated in many vital cellular functions such as stem cell regeneration and organogenesis. Several intra-cellular signal transduction pathways are induced by Wnt, notably the Wnt/beta-catenin dependent pathway or canonical pathway and the non-canonical or beta-catenin-independent pathway; the latter includes the Wnt/Ca2+ and Planar Cell Polarity pathway (PCP). Wnt activation occurs at the intestinal crypt floor, and is critical to optimal maintenance of stem cells. Colorectal cancers show evidence of Wnt signaling pathway activation and this is associated with loss of function of the tumor regulator APC. Wnt activation has been observed in breast, lung, and hematopoietic malignancies and contributes to tumor recurrence. The Wnt pathway cross talks with the Notch and Sonic Hedgehog pathways, which has implications for therapeutic interventions in cancers. There are significant challenges in targeting the Wnt pathway, including finding agents that are efficacious without damaging the system of normal somatic stem cell function in cellular repair and tissue homeostasis. Here, we comprehensively review the Wnt pathway and its interactions with the Notch and Sonic Hedgehog pathways. We present the state of the field in effectors and inhibitors of Wnt signaling, including updates on clinical trials in various cancers with inhibitors of Wnt, Notch, and Sonic Hedgehog. PMID- 29169147 TI - C-type lectin receptors in anti-fungal immunity. AB - Host immune systems are constantly engaged with fungal pathogens which are common in environments as well as in healthy human skin and mucosa. C-type lectin receptors (CLRs) are expressed in myeloid cells and play central roles in host defenses against fungal infections by coordinating innate and adaptive immune systems. Upon ligand binding, CLRs stimulate cellular responses by inducing the production of cytokines and reactive oxygen species via the Syk/CARD9 signaling pathway, leading to fungal elimination. Due to identification and characterization of the CLRs, the underlying mechanisms of the anti-fungal immunity are being unveiled in the present decade. In this review, we focus on the anti-fungal activities of CLRs and summarize of current knowledge of the related expression profiles, modes of ligand recognition, and signaling cascades.

AB - CRISPR-Cas systems are adaptive immune systems that protect their hosts from predation by bacteriophages (phages) and parasitism by other mobile genetic elements (MGEs). Given the potent nuclease activity of CRISPR effectors, these enzymes must be carefully regulated to minimize toxicity and maximize anti-phage immunity. While attention has been given to the transcriptional regulation of these systems (reviewed in [1]), less consideration has been given to the crucial post-translational processes that govern enzyme activation and inactivation. Here, we review recent findings that describe how Cas nucleases are controlled in diverse systems to provide a robust anti-viral response while limiting auto immunity. We also draw comparisons to a distinct bacterial immune system, restriction-modification. PMID- 29169148 TI - Selenite-induced nitro-oxidative stress processes in Arabidopsis thaliana and Brassica juncea. AB - Extremes of selenium (Se) exert toxic effects on plants' physiological processes; although plant species tolerate Se differently. This study focuses on the effect of Se (0, 20, 50 or 100MUM sodium selenite) on secondary nitro-oxidative stress processes mainly using in situ microscopic methods in non-accumulator Arabidopsis thaliana and secondary Se accumulator Brassica juncea. Relative Se tolerance or sensitivity of the species was evaluated based on growth parameters (fresh and dry weight, root growth) and cell viability. Besides, selenite-triggered cell wall modifications (pectin, callose) and stomatal regulations were determined for the first time. In case of Arabidopsis, relative selenite sensitivity was accompanied by decreased stomatal density and induced stomatal opening, callose accumulation, pronounced oxidative stress and moderate nitrosative modifications. In contrast, the selenite-treated, relatively tolerant Brassica juncea showed larger number of more opened stomata, pectin accumulation, moderate oxidative and intense nitrosative stress. These suggest that selenite tolerance or sensitivity is rather associated with oxidative processes than secondary nitrosative modifications in higher plants. PMID- 29169149 TI - Prokaryotic Expression and Anti-IBDV Activity of Chicken Interleukin-18 and Interferon-gamma. AB - Interferon-gamma (IFN-gamma), a cytokine produced by activated natural killer cells and T lymphocytes, is an important regulator of innate and adaptive immunity. Interleukin (IL)-18, also known as IFN-gamma-inducing factor, is a cytokine that induces T and natural killer cells to produce IFN-gamma. In this study, the chicken IL-18 (ChIL-18) and chicken IFN-gamma (ChIFN-gamma) genes were inserted into the pET28a prokaryotic expression vector, resulting in pET28a-IL-18 and pET28a-IFN-gamma, respectively. These plasmids were transformed into Escherichia coli strain BL21, and the ChIL-18 and ChIFN-gamma proteins were expressed and purified. To determine their antiviral activities, 200 ng/mL of ChIL-18 and/or ChIFN-gamma were inoculated into chicken embryonic fibroblast cells. After 24 h, one 50% tissue culture infective dose (TCID50) of infectious bursal disease virus (IBDV) was inoculated into the chicken embryonic fibroblast cells. The results showed that the antiviral effect of ChIL-18 and ChIFN-gamma in combination was better than that of ChIL-18 or ChIFN-gamma alone. Next, 14-day old chicken were injected with 200 ug of ChIL-18 and/or ChIFN-gamma and then were challenged with 103 TCID50 of IBDV via intraperitoneal injection. The results showed that the proliferation of IBDV was inhibited by the injection of the recombinant proteins, especially the combination of ChIL-18 and ChIFN-gamma, as evidenced by cytokine detection, quantitative PCR, and pathology analyses. These results indicate that ChIL-18 and ChIFN-gamma could inhibit IBDV infection and the combination of ChIL-18 and ChIFN-gamma has a better inhibitory effect than either cytokine alone. PMID- 29169150 TI - Multiple Roles of Autophagy in the Sorafenib Resistance of Hepatocellular Carcinoma. AB - Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related death worldwide, and prognosis remains unsatisfactory since the disease is often diagnosed at the advanced stages. Currently, the multikinase inhibitor sorafenib is the only drug approved for the treatment of advanced HCC. However, primary or acquired resistance to sorafenib develops, generating a roadblock in HCC therapy. Autophagy is an intracellular lysosomal pathway involved in protein and organelle degradation, with an astonishing number of connections to human disease and physiology. Current understanding of the role of autophagy in the progression of cancer and the response to cancer therapy remains controversial. Sorafenib is able to induce autophagy in HCC, but the effect of autophagy is indistinct. Some studies established that sorafenib-induced autophagy serves as a pro-survival response. However, other studies found that sorafenib-induced autophagy improves the lethality of sorafenib against HCC cells. The mechanisms underlying autophagy and sorafenib resistance remain elusive. The purpose of this review is to summarize the progress of research focused on autophagy and sorafenib resistance and to update current knowledge of how cellular autophagy impacts sorafenib sensitivity in HCC treatment. PMID- 29169151 TI - Cystic Lung Disease in Genetic Syndromes with Deficient Tumor Suppressor Gene Function. AB - Cystic lung diseases constitute a distinct group of rare lung disorders, among which two result from monogenic defects affecting tumor suppressor genes: lymphangioleiomyomatosis, either sporadic or associated with tuberous sclerosis complex, and Birt-Hogg-Dube syndrome. These disorders have similarities in their clinical expression, including occurrence in young adults, multiple pulmonary cysts, recurrent pneumothorax, skin hamartomas, and renal tumors. However, they markedly differ in their gender distribution, pathogenesis, disease course, and prognosis. Our knowledge on these two rare conditions is rapidly expanding. Management of lymphangioleiomyomatosis has substantially improved in the past decade with the understanding of its pathogenic mechanisms, the discovery of an effective therapy, and development of large cohorts and international guidelines. Birt-Hogg-Dube syndrome has been described more recently and still awaits deeper understanding of its pathophysiology. PMID- 29169152 TI - Knockdown of CAVEOLIN-1 Sensitizes Human Basal-Like Triple-Negative Breast Cancer Cells to Radiation. AB - BACKGROUND/AIMS: Triple-negative breast cancer (TNBC) is a high-risk breast cancer phenotype without specific targeted therapy options and is significantly associated with increased local recurrence in patients treated with radiotherapy. CAVEOLIN-1 (CAV-1)-mediated epidermal growth factor receptor (EGFR) nuclear translocation following irradiation promotes DNA repair and thus induces radiation resistance. In this study, we aimed to determine whether knockdown of CAV-1 enhances the radiosensitivity of basal-like TNBC cell lines and to explore the possible mechanisms. METHODS: Western blotting was used to compare protein expression in a panel of breast cancer cell lines. Nuclear accumulation of EGFR as well as DNA repair and damage at multiple time points following irradiation with or without CAV-1 siRNA pretreatment were investigated using western blotting and confocal microscopy. The radiosensitizing effect of CAV-1 siRNA was evaluated using a clonogenic assay. Flowcytometry was performed to analyse cell apoptosis and cell cycle alteration. RESULTS: We found that CAV-1 is over-expressed in basal-like TNBC cell lines and barely expressed in HER-2-positive cells; additionally, we observed that HER-2-positive cell lines are more sensitive to irradiation than basal-like TNBC cells. Our findings revealed that radiation induced EGFR nuclear translocation was impaired by knockdown of CAV-1. In parallel, radiation-induced elevation of DNA repair proteins was also hampered by pretreatment with CAV-1 siRNA before irradiation. Silencing of CAV-1 also promoted DNA damage 24 h after irradiation. Colony formation assays verified that cells could be radiosensitized after knockdown of CAV-1. Furthermore, G2/M cell cycle arrest and apoptosis enhancement may also contribute to the radiosensitizing effect of CAV-1 siRNA. CONCLUSION: Our results support the hypothesis that CAV-1 knockdown by siRNA causes increased radiosensitivity in basal-like TNBC cells. The mechanisms associated with this effect are reduced DNA repair through delayed CAV-1-associated EGFR nuclear accumulation and induction of G2/M arrest and apoptosis through the combined effects of CAV-1 siRNA and radiation. PMID- 29169153 TI - Optimal Trough Concentration of Teicoplanin in Febrile Neutropenic Patients with Hematological Malignancy. AB - BACKGROUND: Teicoplanin is a glycopeptide antibiotic currently used for the treatment of methicillin-resistant Staphylococcus aureus. The need for therapeutic drug monitoring of teicoplanin has been increasingly highlighted as important. It is generally accepted that whereas a plasma trough concentration (Cmin) of >=10 mg/L is appropriate for the majority of infections, it should exceed 20 mg/L for severe infections. The target Cmin of teicoplanin in patients with febrile neutropenia (FN) has not been reported. The aim of this study was to estimate the target Cmin for the treatment of FN in patients with hematological malignancy. METHODS: In this retrospective, single-center, observational cohort study, the records of 52 hospitalized patients with hematological malignancy who were treated with teicoplanin for FN due to bacteriologically documented or presumptive gram-positive infections were analyzed. RESULTS: A significant difference in the first Cmin of teicoplanin was observed between the response and nonresponse groups in patients with bacteremia. The areas under the receiver operating characteristic curves were 0.80 for clinical efficacy. The cut-off value of teicoplanin Cmin on days 4-6 was 15.2 mg/L (sensitivity 80.0%, specificity 75.0%). CONCLUSIONS: The authors propose a target teicoplanin Cmin of >=15.2 mg/L for FN in patients with hematological malignancy. PMID- 29169154 TI - Development of Age-Related Macular Degeneration (AMD) in the Fellow Eye of Patients with AMD Treated by Treat-and-Extend Intravitreal Therapy with Aflibercept. AB - PURPOSE: To evaluate the development of neovascular age-related macular degeneration (nAMD) in the fellow eye in patients with unilateral nAMD treated by a treat-and-extend (TAE) regimen with intravitreal aflibercept injections. METHODS: We retrospectively studied 104 patients with treatment-naive unilateral nAMD. We assessed best-corrected visual acuity (BCVA) and exudative changes in the treated eyes and development of nAMD in the fellow eye for 2 years. RESULTS: The subjects included 46 patients with typical AMD (tAMD), 44 with polypoidal choroidal vasculopathy (PCV), and 14 with retinal angiomatous proliferation (RAP). BCVA was significantly improved after the loading phase in all subtypes. Forty-six patients (44.2%) had no recurrence within 2 years after the loading phase, including 12 (26.1%) with tAMD, 23 (52.2%) with PCV, and 11 (78.6%) with RAP (p < 0.01). Eleven patients (10.6%) developed nAMD in the fellow eye within 2 years, including 4 (8.7%) with tAMD, 0 (0%) with PCV, and 7 (50.0%) with RAP (p < 0.001). CONCLUSIONS: Patients with RAP had significantly more frequent development of nAMD in the fellow eye compared to other subtypes, while they showed significantly less recurrence during the TAE regimen with intravitreal aflibercept injections. Development of nAMD in the fellow eye should be monitored in RAP when the injection interval is extended. PMID- 29169156 TI - Folliculotropism Does Not Affect Overall Survival in Mycosis Fungoides: Results from a Single-Center Cohort and Meta-Analysis. AB - BACKGROUND: Folliculotropic mycosis fungoides (FMF) is a distinct subtype of mycosis fungoides (MF) with unique clinicopathological features. The medical literature suggests that FMF has a more aggressive course and worse survival than classic MF. Previous studies do not use standardized treatment, and no studies have reported an association between treatment response and overall survival (OS). OBJECTIVE: To compare OS for MF, FMF, and Sezary syndrome (SS) patients. METHODS: Data were collected retrospectively from 218 patients (171 MF, 15 SS, 32 FMF) treated in a single academic center between 1970 and 2016. RESULTS: Negative predictors of OS were age (OR = 1.07), male sex (OR = 1.63), and stage IIB, III, and IV (OR = 4.10, 5.42, and 7.54, respectively, vs. stage IA). Lack of initial PUVA response was strongly associated with negative OS (OR = 3.08). Kaplan-Meier analysis of age-, sex-, and stage-matched MF and FMF patients found similar OS between the 2 groups. The 5-year OS was 91% for FMF and 74% for MF. Meta-analysis of current data and 2 published studies where survival of FMF patients was compared to MF did not reveal statistically significant differences between these 2 diseases. CONCLUSIONS: When patients were matched for age, sex, and disease stage, folliculotropism did not affect OS in MF. PMID- 29169155 TI - Rho Kinase Regulates Aortic Vascular Smooth Muscle Cell Stiffness Via Actin/SRF/Myocardin in Hypertension. AB - BACKGROUND/AIMS: Our previous studies demonstrated that intrinsic aortic smooth muscle cell (VSMC) stiffening plays a pivotal role in aortic stiffening in aging and hypertension. However, the underlying molecular mechanisms remain largely unknown. We here hypothesized that Rho kinase (ROCK) acts as a novel mediator that regulates intrinsic VSMC mechanical properties through the serum response factor (SRF) /myocardin pathway and consequently regulates aortic stiffness and blood pressure in hypertension. METHODS: Four-month old male spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats were studied. Aortic stiffness was measured by echography. Intrinsic mechanical properties of VSMCs were measured by atomic force microscopy (AFM) in vitro. RESULTS: Compared to WKY rats, SHR showed a significant increase in aortic stiffness and blood pressure, which is accompanied by a remarkable cell stiffening and ROCK activation in thoracic aortic (TA) VSMCs. Theses alterations in SHR were abolished by Y-27632, a specific inhibitor of ROCK. Additionally, boosted filamentous/globular actin ratio was detected in TA VSMCs from SHR versus WKY rats, resulting in an up regulation of SRF and myocardin expression and its downstream stiffness associated genes including alpha-smooth muscle actin, SM22, smoothelin and myosin heavy chain 11. Reciprocally, these alterations in SHR TA VSMCs were also suppressed by Y-27632. Furthermore, a specific inhibitor of SRF/myocardin, CCG 100602, showed a similar effect to Y-27632 in SHR in both TA VSMCs stiffness in vitro and aorta wall stiffness in vivo. CONCLUSION: ROCK is a novel mediator modulating aortic VSMC stiffness through SRF/myocardin signaling which offers a therapeutic target to reduce aortic stiffening in hypertension. PMID- 29169157 TI - TNF-alpha Regulates Mast Cell Functions by Inhibiting Cell Degranulation. AB - BACKGROUND/AIMS: The aim of this study was to investigate the involvement of inducible co-stimulatory ligand (ICOSL) expression in stimulation of mast cells (MCs) by TNF-alpha and the ability of TNF-alpha stimulation of MCs to influence CD4+ T cell differentiation and function. The mechanisms underlying TNF-alpha stimulation of MCs were also explored. METHODS: Mast cells and CD4+ T cells were prepared from C57BL/6 mice (aged 6-8 weeks). ICOSL expression by MCs was measured by real-time PCR and flow cytometry, and levels of IL-4, IL-10 and IFN-gamma were measured by ELISA. RESULTS: ICOSL expression by MCs was increased by TNF-alpha stimulation, and resulted in interaction with CD4+ T cells. The IL-4 and IL-10 levels in the co-culture system increased, while IFN-gamma levels decreased. Furthermore, CD4+CD25+Foxp3+ T cell proliferation was induced by co-culture with TNF-alpha-stimulated MCs. The mechanism by which TNF-alpha stimulated MCs was dependent on the activation of the MAPK signaling pathway. CONCLUSION: TNF-alpha upregulated the expression of ICOSL on mast cells via a mechanism that is dependent on MAPK phosphorylation. TNF-alpha-treated MCs promoted the differentiation of regulatory T cells and induced a shift in cytokine expression from a Th1 to a Th2 profile by up-regulation ICOSL expression and inhibition of MC degranulation. Our study reveals a novel mechanism by which mast cells regulate T cell function. PMID- 29169158 TI - Potential Targets and Clinical Value of MiR-224-5p in Cancers of the Digestive Tract. AB - BACKGROUND/AIMS: MicroRNAs participate in various biological processes in malignant tumors. However, the mechanisms of miR-224-5p in digestive system cancers are not fully understood. A comprehensive investigation of the clinical value and potential targets of miR-224-5p in cancers of the digestive tract is necessary. METHODS: Expression profiling data and related-prognostic data of miR 224-5p were acquired from Gene Expression Omnibus, The Cancer Genome Atlas, ArrayExpress, and published literature. The potential target mRNAs of miR-224-5p were predicted using bioinformatics methods and finally annotated using Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. RESULTS: MiR-224-5p is up-regulated in digestive system cancers (SMD=0.69, 95% CI: 0.43-0.96, P<0.0001) and exhibits a moderate diagnostic ability (AUC=0.84, 95% CI: 0.80-0.87). Our data also demonstrated that miR-224-5p is statistically significantly correlated with overall survival univariate analysis (HR=1.69, 95% CI: 1.15-2.49, P=0.007) and multivariate analysis (HR=2.39, 95% CI: 1.74-3.30, P<0.0001). In total, 388 potential miR-224 5p target mRNAs were predicted by bioinformatics methods. GO annotation analysis revealed that the top terms of miR-224-5p in biological process, cellular component and molecular function were system development, neuron part, and transcriptional activator activity, RNA polymerase II core promoter proximal region sequence-specific binding, respectively. Moreover, eight pathways were identified in KEGG pathway enrichment analysis. CONCLUSIONS: MiR-224-5p is up regulated and has the potential to become a diagnostic and prognostic biomarker in digestive system cancers. MiR-224-5p might play vital roles in cancers of the digestive tract but the exact molecular mechanisms need further study and verification. PMID- 29169159 TI - An Unexpected Lesson in Global Nephrology. PMID- 29169160 TI - The Use of Peritoneal Dialysis in Phenobarbitone Toxicity in a Critically Unwell Neonate. AB - BACKGROUND: Phenobarbitone (PB) is the first-line anti-convulsant for neonatal seizures. The use of peritoneal dialysis (PD) to enhance drug elimination in cases of neonatal PB overdose has not been reported. OBJECTIVE: To report a case of neonatal severe PB toxicity and review the elimination of PB by PD. METHODS: Assessment of PD drug clearance. RESULTS: A neonate with prolonged seizures was administered PB. Encephalopathy and myocardial failure developed, which were initially suspected to be secondary to hypoxia. At 42 h of age, the serum PB concentration was in the toxic range at 131 mg/L. Despite supportive care, the infant's condition deteriorated with escalating inotropes and the need for CPR. Enhanced PB elimination via multiple-dose activated charcoal and exchange transfusion were considered too risky. Hourly PD cycles via Tenckhoff catheter were commenced, based on reports suggesting that PD enhances PB clearance. The clinical state of the infant then improved. PD administration was continued for 60 h, recovering 20% of the estimated total PB body load. The infant survived and there were no PD complications. CONCLUSIONS: PD increased PB clearance in this neonate, correlating with clinical recovery. Where other techniques are not possible, PD may have a role to play in enhancing PB elimination. PMID- 29169161 TI - Digoxin and Hypermagnesuria. AB - In a recent issue of Nephron, Abu-Amer et al.[1] reported the presence of hypermagnesuria in patients following acute intravenous administration of digoxin and suggested that the Na+/K+-ATPase gamma-subunit, which is the pharmacological target of digoxin, can play a role in this process. Hypermagnesuria induced by digoxin may have important clinical consequences, particularly in the presence of inherited and acquired conditions associated with hypermagnesuria and hypomagnesemia. Moreover, the co-administration of digoxin with other drugs that reduce gastrointestinal absorption (i.e., proton pump inhibitors) or increase urinary excretion (i.e., loop diuretics) may increase the likelihood of developing hypomagnesemia. In this article, we reviewed the main causes of hypermagnesuria and discussed potential drug interactions that can enhance the magnesuric effect of digoxin. We suggest that during the administration of digoxin, clinicians should consider the presence of other causes of hypomagnesemia and hypermagnesuria that could enhance the magnesuric effect of digoxin, monitor the urinary and serum levels of magnesium and prescribe an oral supplementation of magnesium. PMID- 29169162 TI - Application of Electrocautery Needle Knife Combined with Balloon Dilatation versus Balloon Dilatation in the Treatment of Tracheal Fibrotic Scar Stenosis. AB - BACKGROUND: Electrocautery needle knives can largely reduce scar and granulation tissue hyperplasia and play an important role in treating patients with benign stricture. OBJECTIVE: The aim of this retrospective study was to evaluate the efficacy and safety of electrocautery needle knife combined with balloon dilatation versus balloon dilatation alone in the treatment of tracheal stenosis caused by tracheal intubation or tracheotomy. METHODS: We retrospectively analysed the clinical data of 43 patients with tracheal stenosis caused by tracheotomy or tracheal intubation in our department from January 2013 to January 2016. Among these 43 patients, 23 had simple web-like stenosis and 20 had complex steno sis. All patients were treated under general anaesthesia, and the treatment methods were (1) balloon dilatation alone, (2) needle knife excision of fibrotic tissue combined with balloon dilatation, and (3) needle knife radial incision of fibrotic tissue combined with balloon dilatation. RESULTS: After treatment the symptoms, such as shortness of breath, were markedly improved immediately in all cases. The stenosis degree of patients who were treated with the elec-trocautery needle knife combined with balloon dilatation had better improvement compared with that of those treated with balloon dilatation treatment alone after 3 months (0.45 +/- 0.04 vs. 0.67 +/- 0.05, p < 0.01), and the proportion of restenosis occurrence that required further treatment was decreased at 6 months (46.9 vs. 81.8%), especially for the web-like stenosis patients, as most of their stenoses dilated with no obvious restenosis and achieved clinical cure. CONCLUSION: Electrocautery needle knife combined with balloon dilatation is an effective and safe treatment for tracheal fibrotic stenosis compared with balloon dilatation alone.

PMID- 29169167 TI - Structural Pulmonary Abnormalities Still Evident in Schoolchildren with New Bronchopulmonary Dysplasia. AB - BACKGROUND: A new pattern of bronchopulmonary dysplasia (BPD) has emerged with the improved survival of preterm children. OBJECTIVES: Our aim was to characterize structural abnormalities associated with new BPD and to evaluate whether the severity of high-resolution computed tomography (HRCT) changes is associated with lung function. METHODS: HRCT scans were performed on 21 schoolchildren with a history of new BPD (mild, n = 9; moderate, n = 4; and severe, n = 8) with a mean age of 12.7 years (range: 8.7-16.7). Scans were interpreted by 2 radiologists using a structured scoring system. Spirometry (forced expiratory volume in 1 s [FEV1] and maximum mid-expiratory flow [MMEF]) and the diffusion capacity of the lung for carbon monoxide (DLCO) were measured. RESULTS: At least 1 HRCT abnormality was evident in 17 children (81%), including linear-to-triangular subpleural opacities (71%), air trapping (29%), mosaic perfusion (24%), peribronchial thickening (14%), and emphysema (14%). The HRCT score was higher in the severe BPD group (11.50; 95% CI 2.86-20.14) than in the mild or moderate BPD group (1.39; 95% CI 0.24-2.54, and 2.75; 95% CI 0.28-5.22, respectively). HRCT scores were inversely related to FEV1 (beta -4.23; 95% CI 6.97 to -1.49, p = 0.004) and MMEF (beta -3.45; 95% CI -6.10 to -0.80, p = 0.013) but not to DLCO. The duration of the initial mechanical ventilation was associated with HRCT scores (p = 0.014). CONCLUSIONS: Structural lung abnormalities are common among schoolchildren with a history of new BPD, resembling abnormalities described in the presurfactant era. HRCT abnormalities are associated with the duration of early mechanical ventilation and the severity of BPD and they are correlated with spirometry. PMID- 29169168 TI - Anterior Borderzone Angle for Hemodynamic Collateral Metric in Patients with Symptomatic Middle Cerebral Artery Stenosis. AB - BACKGROUND AND AIMS: We aimed to introduce a parameter of anterior borderzone angle (ABZA) to quantitatively evaluate the ACA-MCA leptomeningeal collaterals for middle cerebral artery stenosis (MCAS). METHODS: Two hundred seventy-five patients with 50-100% MCAS and 100 controls were included. The 95% reference range of ABZA was obtained from the controls. ABZAtrans was defined as "ABZA/the 95% upper limit." Relationships between ABZA and MCAS, -ABZAtrans and the TICI grade, the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) collateral grade were analyzed. An ABZA grade model for the ACA leptomeningeal collaterals was tentatively developed. RESULTS: The 95% reference range of ABZA was 0.0o-23.0o. ABZA was significantly associated with MCAS by a function of the fourth power (R2 = 0.723, p < 0.001), and could predict hemodynamic MCAS (>=70%) with an AUC of 0.928 (95% CI 0.903-0.953). ABZAtrans was negatively correlated with the TICI grade (rho = -0.752, p < 0.001) and positively with the ASITN/SIR grade (rho = 0.921, p < 0.001). The ABZA grade was created by rounding -ABZAtrans to a nearest integer, and was closely associated with the ASITN/SIR grade (rho = 0.894, p < 0.001). CONCLUSIONS: ABZA can be used as a hemodynamic parameter to quantitatively evaluate ACA leptomeningeal collaterals. PMID- 29169169 TI - Effects and Interactions of Prenatal Ethanol Exposure, a Post-Weaning High-Fat Diet and Gender on Adult Hypercholesterolemia Occurrence in Offspring Rats. AB - BACKGROUND/AIMS: Prenatal ethanol exposure (PEE) could induce intrauterine programming of hypothalamic-pituitary-adrenal axis-associated neuroendocrine metabolism, resulting in intrauterine growth retardation and susceptibility to adult hypercholesterolemia in offspring. This study aimed to analyse the effects and interactions of PEE, a post-weaning high-fat diet (HFD) and gender on the occurrence of adult hypercholesterolemia in offspring rats. METHODS: Wistar female rats were treated with ethanol (4 g/kg.d) at gestational days 11-20. The offspring were given a normal diet or HFD after weaning, and the blood cholesterol metabolism phenotype and expression of hepatic cholesterol metabolism related genes were detected in 24-week-old offspring. Furthermore, the interactions among PEE, HFD, and gender on hypercholesterolemia occurrence were analysed. RESULTS: PEE increased the serum total cholesterol (TCH) and low density lipoprotein-cholesterol (LDL-C) levels and decreased the serum high density lipoprotein-cholesterol (HDL-C) level in adult offspring rats; the changes in female offspring were greater than those in males. At the same time, the mRNA expression levels of hepatic cholesterol metabolic enzymes (apolipoprotein B (ApoB) and 7alpha-hydroxylase (CYP7A1))-were increased, while the mRNA expression levels of the scavenger receptor B1 (SR-B1) and LDL receptor (LDLR) were decreased. Furthermore, a three-way ANOVA showed there were interactions among PEE, post-weaning HFD and gender. For PEE offspring, a post weaning HFD aggravated the elevated hepatic ApoB and CYP7A1 expression and reduced SR-B1 and LDLR expression; the changes in hepatic SR-B1 and CYP7A1 expression were greater in female HFD rats than in males. CONCLUSION: Our findings suggest that a post-weaning HFD could aggravate offspring hypercholesterolemia caused by PEE and that this mechanism might be associated with hepatic cholesterol metabolic disorders that are aggravated by a post weaning HFD; hepatic cholesterol metabolism was more sensitive to neuroendocrine metabolic alterations by PEE and a post-weaning HFD in the female offspring than in the male offspring. PMID- 29169170 TI - Mite-Induced Asthma and IgE Levels to Shrimp, Mite, Tropomyosin, Arginine Kinase, and Der p 10 Are the Most Relevant Risk Factors for Challenge-Proven Shrimp Allergy. AB - BACKGROUND: Shrimp sensitization is common in the general population, but the presence of symptoms is only moderately related to sensitization. A point still at issue is which in vivo and/or in vitro tests (food challenge, component resolved diagnosis, house dust mite [HDM] sensitization) can help in distinguishing shrimp-allergic subjects from subjects that are sensitized but tolerant. METHODS: The aim of this study was to evaluate the role of IgE to the different shrimp and mite allergens in distinguishing shrimp challenge-positive from challenge-negative patients. Subjects with suspected hypersensitivity reactions to shrimp, positive skin prick tests (SPTs), and/or anti-shrimp IgE were submitted to open and double-blind placebo-controlled food challenges (DBPCFC). Specific IgE to shrimp, mites, and the recombinants rPen a 1, rDer p 1, 2, and 10 were tested using ImmunoCAP-FEIA. IgE immunoblotting was performed to identify the patients' allergenic profiles. RESULTS: In total, 13 out of 51 (25.5%) patients with reported reactions to shrimp were truly shrimp allergic (7 DBPCFC positive and 6 with documented severe reactions). These patients had significantly higher skin test wheal diameters than nonallergic patients, as well as higher levels of IgE to rPen a 1 and rDer p 10. HDM-induced asthma and the simultaneous presence of anti-nDer p 1, 2, and 10 IgE levels increased the risk of true shrimp allergy. CONCLUSION: Food challenge tests are mandatory for the diagnosis of shrimp allergy. Tropomyosin is associated with clinical reactivity. HDM-induced asthma and anti-mite IgE are risk factors for shrimp allergy. PMID- 29169171 TI - MiRNAs are Unlikely to be Involved in Retinoid Receptor Gene Regulation in Pancreatic Cancer Cells. AB - BACKGROUND/AIMS: Retinoid receptors and retinoic acid were reported to be down regulated in pancreatic duct adenocarcinoma (PDAC) compared to normal pancreas. Yet the mechanism of the down-regulation of retinoid receptors is not well defined. The aim of this study was to find out whether selected dysregulated miRNAs in PDAC are responsible for the decreased level of retinoid receptors. METHODS: Bioinformatics, real-time PCR, western blot analysis as well as molecular manipulation with miRNA in cells of PDAC were carried out. RESULTS: We first performed bioinformatics research to identify conserved target sequences for deregulated miRNAs within the 3'UTR region of retinoid receptor mRNA. This research revealed binding sites for miR-138, -27a, -27b, -206, -613, -9-5p, 27a/b-3p and -27a. Next, we investigated the expression of selected retinoid receptors and miRNAs in PDAC cell lines and in the Human Pancreatic Duct Epithelial (HPDE) cell line. Further, we investigated the effects of modifying expression levels of selected miRNAs using miRNA inhibitors or mimics. We demonstrated that none of these miRNAs can target the selected retinoid receptors in vitro. CONCLUSIONS: miR-27a, miR-27b, miR-9, miR10a and miR-10b were up regulated in PDAC cells compared to HPDE cells. The up-regulation of these miRNAs was not responsible for the down-regulation of RARalpha, RARbeta, RXRalpha and RXRbeta in PDAC cells.

AB - BACKGROUND/AIMS: Melatonin is a hormone transferring information about duration of darkness to the organism and is known to modulate several signaling pathways in the cells, e.g. generation of endoplasmic reticulum stress, oxidative status of the cells, etc. Melatonin has been shown to exert antiproliferative and cytotoxic effects on various human cancers. We proposed that this hormone can differently affect tumour cells and healthy cells. METHODS: We compared the effect of 24 h melatonin treatment on calcium transport (by fluorescent probes FLUO-3AM and Rhod-5N), ER stress (determined as changes in the expression of CHOP, XBP1 and fluorescently, using Thioflavin T), ROS formation (by CellROX(r) Green/Orange Reagent) and apoptosis induction (by Annexin-V FLUOS/propidiumiodide) in two tumour cell lines - ovarian cancer cell line A2780 and stable cell line DLD1 derived from colorectal carcinoma, with non-tumour endothelial cell line EA.hy926. RESULTS: Melatonin increased apoptosis in both tumour cell lines more than twice, while in EA.hy926 cells the apoptosis was increased only by 30%. As determined by silencing with appropriate siRNAs, both, type 1 sodium/calcium exchanger and type 1 IP3 receptor are involved in the apoptosis induction. Antioxidant properties of melatonin were significantly increased in EA.hy926 cells, while in tumour cell lines this effect was much weaker. CONCLUSION: Taken together, melatonin has different antioxidative effects on tumour cells compared to non-tumour ones; it also differs in the ability to induce apoptosis through the type 1 sodium/calcium exchanger, and type 1 IP3 receptor. Different targeting of calcium transport systems in tumour and normal, non-tumour cells is suggested as a key mechanism how melatonin can exert its anticancer effects. Therefore, it might have a potential as a novel therapeutic implication in cancer treatment.

AB - BACKGROUND/AIMS: Prior studies have shown that bufalin inhibits cellular proliferation and induces apoptosis in various human cancers. MicroRNA-203 (miR 203) has been shown to function as an important regulator of tumor progression at various stages. In this study, we investigated the effect of miR-203 expression and bufalin treatment on glioma cell proliferation and stem cell-like phenotypes. METHODS: We used cell viability assay, colony formation assay, cell apoptosis assay and neurosphere formation assay to dectect the treatment effect of bufalin on U251 and U87 cells. Cells were transfected with the miR-203 mimic without bufalin treatment or cells were transfected with anti-miR-203 under bufalin treatment, the above expreiments were repeated. RT-PCR was employed to quantify miR-203 expression. Western blot was performed to detect the stem cell-like (CSC) markers, OCT4 and SOX2. Luciferase activity assay was used to determine whether the SPARC is the target of miR-203. RESULTS: Bufalin treatment inhibited cell proliferation, colony formation, and CSC phenotypes and increased cell apoptosis and expression of miR-203. Furthermore, overexpression of miR-203 led to similar outcomes as bufalin treatment with respect to the cell viability, colony formation, cell apoptosis and the phenotypes of glioma cells. While anti-miR-203 attenuated the inhibitory effects of bufalin as promoting cell proliferation, colony formation and CSC phenotyes and inhibiting cell apoptosis. In addition, we identified SPARC as a novel target gene of miR-203. CONCLUSIONS: These findings suggest that miR-203 plays an important role in bufalin's ability to inhibit the growth of glioma cells and the development of stem cell-like phenotypes. PMID- 29169176 TI - Ablation of ATG4B Suppressed Autophagy and Activated AMPK for Cell Cycle Arrest in Cancer Cells. AB - BACKGROUND/AIMS: ATG4B is a cysteine protease required for autophagy, which is a cellular catabolic pathway involved in energy balance. ATG4B expression is elevated during tumor growth in certain types of cancer, suggesting that ATG4B is an attractive target for cancer therapy. However, little is known about the mechanisms through which ATG4B deprivation suppresses the growth of cancer cells. METHODS: Cancer cells were transfected with either siRNA against ATG4B or an expression vector encoding wild-type ATG4BWT or encoding catalytic mutant ATG4BC74A to determine cell cycle progression by propidium iodide staining or by BrdU incorporation assay using flow cytometry. The GFP-MAP1LC3-II puncta and protein levels in the cells were determined by immunofluorescence and immunoblotting, respectively. RESULTS: Knockdown of ATG4B blocked cell proliferation, particularly at the G1-S phase transition, in various cancer cells. Moreover, knockdown of ATG4B or overexpression of the ATG4BC74A catalytic mutant reduced both autophagic flux and ATP levels and increased AMP-activated protein kinase (AMPK) phosphorylation in the cancer cells. Nevertheless, knockdown of ATG4B had only a minor effect on AMPK activation and G1 phase arrest in liver kinase B1 (LKB1)-deficient or AMPK-inhibited cancer cells. CONCLUSION: These results imply that targeting ATG4B might inhibit autophagy and trigger the LKB1-AMPK energy-sensing pathway, resulting in tumor growth suppression. PMID- 29169177 TI - Acute Kidney Injury in Elderly Population: A Prospective Observational Study. AB - BACKGROUND/AIMS: Acute kidney injury (AKI) has been reported as a recognized condition among the elderly population; however, its clinical epidemiology is still poorly evaluated. We propose to evaluate the epidemiological profile of AKI in hospitalized elderly patients and the variables associated with renal replacement therapy (RRT) dependency at discharge after an episode of AKI. METHODS: This prospective observational study enrolled 286 elderly patients (aged >=60 years), who had a diagnosis of AKI and were admitted to a tertiary care hospital. Clinical data were analyzed, which included RRT indication, referral time to nephrologist support, standby period in the emergency care units (ECU) before a transfer to an intensive care unit, staff criteria used to indicate palliative care, and the incidence of patients who stayed on chronic dialysis for at least 6 months after discharge. RESULTS: The overall hospital mortality was 56.3%. Acute Kidney Injury Network (AKIN) 3 at the time of admission was significantly higher in patients who underwent RRT. Intrinsic AKI (p < 0.001), AKIN 3 (p < 0.001), RRT (p < 0.001), and increased length of stay in ECUs (p = 0.01) all had a significantly higher prevalence among non-survivors. On multivariate analysis, however, only renal aetiology (intrinsic AKI) was independently associated with mortality (OR 2.88; 95% CI [1.29-6.13]). Approximately 85% of the discharged patients (n = 125) were dialysis free and 36.4% of them who had a previous diagnosis of chronic kidney disease (CKD) upon admission had a worse renal function. Age, AKIN 3, RRT, prior history of CKD, diabetes mellitus, and the number of hemodialysis sessions showed to have an impact on dialysis dependence. Furthermore, 24 of 161 patients who had a dialysis indication were placed on palliative care. CONCLUSIONS: The severity of AKI and the need for RRT were risk factors for mortality and dependence on dialysis. Antecedents of CKD seem to be associated with a poor renal outcome following an AKI episode. Starting RRT had an impact on the clinical decision to enroll these patients into palliative care. PMID- 29169178 TI - Subjective Assessment of Sleep in Huntington Disease: Reliability of Sleep Questionnaires Compared to Polysomnography. AB - INTRODUCTION: The aim of the study was to evaluate the clinical reliability of subjective sleep evaluation, based on sleep and psychometric questionnaires, by comparing the results with those obtained with laboratory-based video polysomnography (V-PSG). PATIENTS AND METHODS: Thirty consecutive Huntington disease (HD) patients were enrolled. Subjective evaluation of sleep included the Pittsburgh Sleep Quality Index (PSQI), the sleep questionnaire for HD (HDQ), the Epworth Sleepiness Scale, the Bologna questionnaire for sleepiness (BQ), the Berlin questionnaire, and the RBD questionnaire; the International Restless Legs Syndrome Study Group scale was administered to patients with positive screening. The psychometric evaluation included the Zung Anxiety Scale, the short form of the Beck Depression Inventory, and the Maudsley Obsessive-Compulsive Inventory. All patients underwent V-PSG. RESULTS: In sleepiness evaluation, the Epworth score was above the cutoff in 6 subjects, and the BQ detected a "high risk" of sleepiness in 7 cases. The results were concordant in 24 and discordant in 5 cases. In the evaluation of sleep quality, the PSQI score was above the cutoff in 18 subjects. According to the HDQ, 10 subjects were poor sleepers. The results were concordant with the PSQI in 20 subjects. DISCUSSION: All comparisons between scale scores and PSG results showed poor or totally absent concordance between subjective and objective measures. SIGNIFICANCE: The subjective evaluation of sleep in HD patients shows a poor correlation with PSG results. PMID- 29169179 TI - Apolipoprotein E e4 Allele Is Associated with Subjective Cognitive Decline: A Meta-Analysis. AB - BACKGROUND AND PURPOSE: Subjective cognitive decline (SCD) is a condition associated with increased risk of Alzheimer's disease. This study performs a meta analysis to estimate the prevalence of the Apolipoprotein E e4 (APOE e4) allele in SCD and the association of APOE e4 with SCD. METHODS: The MEDLINE, EMBASE, and Cochrane Library databases were searched. Meta-analyses were conducted using STATA 12.0 software. When significant heterogeneity was present (I2 >50% and p < 0.05), we conducted stratified and meta-regression analyses to explore possible reasons for heterogeneity. RESULTS: We selected a total of 28 studies that were conducted in Australia, the United States, northern Europe, middle Europe, southern Europe, and Asia. The sample size of the SCD group was 6,044. Thirteen studies included a healthy control group (total control cohort of 3,822), whereas the remaining 15 studies were single-arm studies of SCD groups. The APOE e4 allele was associated with SCD (OR 1.12 [1.00-1.25]; p = 0.04). The pooled estimate for APOE e4 carrier prevalence was 32% (95% CI 28-35). Due to the significant heterogeneity in prevalence estimates, we performed stratified and meta-regression analyses and found that age and northern European residency were significantly associated with heterogeneity. CONCLUSION: The results of this meta analysis indicate a weak association between APOE e4 and SCD. Age and northern European residency are the critical factors that determine heterogeneity in the APOE e4-associated prevalence of SCD. PMID- 29169180 TI - Mitochondria-Targeted Antioxidant Mito-Tempo Protects Against Aldosterone-Induced Renal Injury In Vivo. AB - BACKGROUND/AIMS: Growing evidence suggests mitochondrial dysfunction (MtD) and the Nlrp3 inflammasome play critical roles in chronic kidney disease (CKD) progression. We previously reported that Aldosterone (Aldo)-induced renal injury in vitro is directly caused by mitochondrial reactive oxygen species (mtROS) mediated activation of the Nlrp3 inflammasome. Here we aimed to determine whether a mitochondria-targeted antioxidant (Mito-Tempo) could prevent Aldo-induced kidney damage in vivo. METHODS: C57BL/6J mice were treated with Aldo and/or Mito Tempo (or ethanol as a control) for 4 weeks. Renal injury was evaluated by Periodic Acid-Schiff reagent or Masson's trichrome staining and electron microscopy. ROS were measured by DCFDA fluorescence and ELISA. MtD was determined by real-time PCR and electron microscopy. Activation of the Nlrp3 inflammasome and endoplasmic reticulum stress (ERS) was detected via western blot. RESULTS: Compared with control mice, Aldo-infused mice showed impaired renal function, increased mtROS production and MtD, Nlrp3 inflammasome activation, and elevated ERS. We showed administration of Mito-Tempo significantly improved renal function and MtD, and reduced Nlrp3 inflammasome activation and ERS in vivo. CONCLUSION: Mitochondria-targeted antioxidants may attenuate Aldo-infused renal injury by inhibiting MtD, the Nlrp3 inflammasome, and ERS in vivo. Therefore, targeting mtROS might be an effective strategy for preventing CKD. PMID- 29169182 TI - Gemcitabine plus platinum-based chemotherapy for first-line treatment of hepatocholangiocarcinoma: an AGEO French multicentre retrospective study. AB - BACKGROUND: Hepatocholangiocarcinoma (cHCC-ICC) is a rare liver tumour for which no data on chemosensitivity exist. The aims of this multicentre study were to evaluate overall survival (OS), progression-free survival (PFS), and prognostic factors in cHCC-ICC treated by gemcitabine plus platinum as first-line. METHODS: Unresectable cHCC-ICC treated by gemcitabine plus platinum-based chemotherapy between 2008 and 2017 were retrospectively analysed. Diagnosis was based on histology or, in case of ICC or HCC histology, on discordant computerised tomography scan enhancement patterns associated with discordant serum tumour marker elevation suggesting the alternative tumour. OS and PFS were evaluated by Kaplan-Meier method and prognostic factors by Log-rank test and Cox model. RESULTS: Among 30 patients included, cHCC-ICC was histologically proven in 22 (73.3%). 18 (60%) received gemcitabine plus oxaliplatin (GEMOX), 9 (30%) GEMOX plus bevacizumab, and 3 (10%) gemcitabine plus cisplatin. RECIST criteria were reported in 28 patients: 8 (28.6%) showed partial response, 14 (50%) stable disease, and 6 (21.4%) tumour progression at first evaluation. Median PFS and OS were 9.0 and 16.2 months, respectively. Serum bilirubin ?30 MUmol l-1 (P=0.001) and positive serology for HBV and/or HCV (P=0.014) were independent poor prognostic factors for OS. CONCLUSIONS: Gemcitabine plus platinum-based chemotherapy is effective as first-line for advanced cHCC-ICC. PMID- 29169181 TI - Inflammatory cytokine IL-8/CXCL8 promotes tumour escape from hepatocyte-induced dormancy. AB - BACKGROUND: Breast cancers can recur after a long latency period following 'successful' primary treatments. Chronic inflammation significantly correlates with reduced diseased-free survival in breast cancer patients and could be a point of intervention to prevent recurrence. Liver is among the main sites of breast cancer recurrence. Thus, we hypothesise that inflammatory signals from hepatic stellate cells, the major inflammatory regulators in the sinusoid, could stimulate dormant cancer cells to emerge. METHODS: We utilise in vitro co-culture of breast cancer cells with stellate cells and an ex vivo 3D human liver micro physiologic system to identify stellate cells-derived factors that mediate tumour emergence. RESULTS: Activated, but not quiescent, hepatic stellate cells secreted soluble factors to induce the proliferation of MCF7 and MDA-MB231 cancer cells. IL-8 and MCP-1 were highly secreted by the activated stellate cells and primary human non-parenchymal cells. IL-8 significantly reduced serum-starvation growth arrest on MDA-MB231 cells in vitro and increased cancer proliferation ex vivo. Blocking IL-8Rb/CXCR2 reduced IL-8-induced cancer growth and proliferation. CONCLUSIONS: Activated stellate cells can induce breast cancer emergence from dormancy in the liver by secreting inflammatory cytokines. Preventing liver inflammation or disrupting the subsequent key cytokines may prevent metastatic outgrowth. PMID- 29169183 TI - MYC regulation of glutamine-proline regulatory axis is key in luminal B breast cancer. AB - BACKGROUND: Altered cellular metabolism is a hallmark of cancer and some are reliant on glutamine for sustained proliferation and survival. We hypothesise that the glutamine-proline regulatory axis has a key role in breast cancer (BC) in the highly proliferative classes. METHODS: Glutaminase (GLS), pyrroline-5 carboxylate synthetase (ALDH18A1), and pyrroline-5-carboxylate reductase 1 (PYCR1) were assessed at DNA/mRNA/protein levels in large, well-characterised cohorts. RESULTS: Gain of PYCR1 copy number and high PYCR1 mRNA was associated with Luminal B tumours. High ALDH18A1 and high GLS protein expression was observed in the oestrogen receptor (ER)+/human epidermal growth factor receptor (HER2)- high proliferation class (Luminal B) compared with ER+/HER2- low proliferation class (Luminal A) (P=0.030 and P=0.022 respectively), however this was not observed with mRNA. Cluster analysis of the glutamine-proline regulatory axis genes revealed significant associations with molecular subtypes of BC and patient outcome independent of standard clinicopathological parameters (P=0.012). High protein expression of the glutamine-proline enzymes were all associated with high MYC protein in Luminal B tumours only (P<0.001). CONCLUSIONS: We provide comprehensive clinical data indicating that the glutamine-proline regulatory axis plays an important role in the aggressive subclass of luminal BC and is therefore a potential therapeutic target. PMID- 29169185 TI - Co-culture of human alveolar epithelial (hAELVi) and macrophage (THP-1) cell lines. AB - The air-blood barrier is mainly composed of alveolar epithelial cells and macrophages. Whereas the epithelium acts as a diffusional barrier, macrophages represent an immunological barrier, in particular for larger molecules and nanoparticles. This paper describes a new co-culture of human cell lines representing both cell types. Acquiring, culturing and maintaining primary alveolar epithelial cells presents significant logistical and technical difficulties. The recently established human alveolar epithelial lentivirus immortalized cell line, hAELVi, when grown on permeable filters, form monolayers with high functional and morphological resemblance to alveolar type I cells. To model alveolar macrophages, the human cell line THP-1 was seeded on pre-formed hAELVi monolayers. The co-culture was characterized regarding cellular morphology, viability and barrier function. Macrophages were homogenously distributed on the epithelium and could be kept in co-culture for up to 7 days. Transmission electron microscopy showed loose contact between THP-1 and hAELVi cells. When grown at air liquid interface, both cells were covered with extracellular matrix-like structure, which was absent in THP-1 mono culture. In co-culture with macrophages, hAELVi cells displayed similar, sometimes even higher, trans-epithelial electrical resistance than in mono-cultures. When exposed to silver and starch NPs, hAELVi mono-cultures were more tolerant to the particles than THP-1 mono-cultures. The viability in the co-culture was similar to that of hAELVi monocultures. Transport studies with sodium fluorescein in presence/absence of EDTA proved that the co culture acts as functional diffusion barrier. These data demonstrate that hAELVi-/THP-1 co-cultures represent a promising model for safety and permeability studies of inhaled chemicals, drugs and nanoparticles. PMID- 29169186 TI - Prenylated Flavonoids and Phenolic Compounds from the Rhizomes of Marine Phanerogam Cymodocea nodosa. AB - Chemical investigation of the rhizomes of the marine phanerogam Cymodocea nodosa resulted in the isolation of two new prenylated flavon-di-O-glycosides, cymodioside A (1: ) and B (2: ), along with known phenolic compounds 3: -7: , some of which never reported from seagrasses to date. The structures of compounds 1: and 2: were established by extensive nuclear magnetic resonance analysis. In addition, the absolute configuration of 4-(2,5-dihydroxyhexyl) benzene-1,2-diol (7: ), which was not previously reported in the literature, has been now determined. PMID- 29169184 TI - HER2 expression patterns in paired primary and metastatic endometrial cancer lesions. AB - BACKGROUND: Despite successful implementation of drugs targeting the human epidermal growth factor receptor 2 (HER2) receptor in breast and gastric cancers, the potential of HER2 as a therapeutic target in other cancers has been less studied, including endometrial cancer. We investigated expression levels of HER2 (ERBB2) in a large cohort of endometrial cancer lesions, also including complex atypical hyperplasia and metastatic lesions. METHODS: 67 precursor lesions, 790 primary endometrial cancers and 383 metastatic lesions were investigated for HER2 expression in relation to clinicopathologic features and outcome. Protein levels were assessed by immunohistochemistry (using the HercepTest and staining index (SI) criteria), mRNA levels by microarrays and amplification status by chromogenic in situ hybridisation. RESULTS: High HER2 protein levels were significantly associated with features of aggressive disease and increased mRNA ERBB2 levels. HER2 expression defined by the SI proved to be a better predictor of survival compared with the HercepTest. A discordant HER2 expression pattern between paired primary and metastatic lesions was detected, revealing substantial reduction in HER2 expression from primary to metastatic disease. CONCLUSIONS: Loss of HER2 expression is common in metastatic endometrial cancer lesions and assessment of HER2 levels in the metastatic lesions may be important to define the potential benefit of anti-HER2 treatments in endometrial cancer patients. PMID- 29169187 TI - Biologically Active Orbitides from the Euphorbiaceae Family. AB - A comprehensive overview of natural orbitides isolated from Euphorbiaceae species and their most relevant biological activities are presented. Euphorbiaceae is a large and diverse family, which comprises about 300 genera, and is known as an important source of medicines and toxins. Several classes of secondary metabolites have been described for this taxon, however, orbitides have been broadly reported in Jatropha and Croton genera. Additionally, the latex is documented as the main source of orbitides in this family. Based on their structural and functional diversity, orbitides present a large variety of biological activities described as cytotoxicity, antimalarial, antibacterial, antifungal, enzymatic inhibition, and immunosuppressive, although the mechanism of action still needs to be further investigated. In recent years, the discovery of bioactive cyclic peptides from different sources has grown exponentially, making them promising molecules in the search for new drug leads. This review also highlights the attempts made by many researchers to organize the orbitides nomenclature and amino acid numbering, as well the important progress recently achieved in the biosynthetic study area. PMID- 29169188 TI - Cardiac Autonomic Function, Cardiovascular Risk and Physical Activity in Adolescents. AB - The aims of this study were to investigate in adolescents: 1) the relationships of physical activity (PA) and cardiorespiratory fitness (CRF) to traditional CVD risk factors, rest and recovery autonomic function; and 2) whether autonomic function strengthens the associations between PA, CRF and CVD risk. Fifty-four (22 girls) adolescents had traditional CVD risk factors, rest and recovery autonomic function evaluated. CRF was measured using a steep ramp cycle test and PA was assessed with accelerometers. Resting HRV (and RMSSD30) and heart rate recovery (T30, HHRtau) were used. Clustered traditional (CVDRtrad) and autonomic (CVDRauto) risk scores were created and added to form a composite clustered CVD risk score (CVDRcom). PA and CRF were significantly and negatively associated with traditional CVD risk factors. Moderate (MPA) and vigorous (VPA) were positively related to resting RMSSD, and negatively related to T30 and HHRtau (all P<0.05). RMSSD30 recovered faster in the high compared to low median split for VPA. Stronger associations for CVDRcom compared to CVDRtrad were observed for MPA (CVDRcom: r2=0.32, P=<0.001; CVDRtrad: r2=0.17, P=0.002), and VPA (CVDRcom: r2=0.18, P=0.001; CVDRtrad: r2=0.06, P=0.08). These findings strengthen the proposed additional beneficial effects of PA on autonomic function above traditional CVD risk factors. PMID- 29169189 TI - Lifelong Voluntary Exercise Modulates Age-Related Changes in Oxidative Stress. AB - The hypothesis that aging and regular physical activity could influence oxidative stress has been studied by comparing antioxidant activities (superoxide dismutase (SOD), glutathione peroxidase (GPX), glutathione reductase (GR), ascorbic acid and alpha-Tocopherol) and malondialdehyde level (MDA) in four groups: young sedentary (n=15; age: 20.3+/-2.8 years; YS), young active (n=16; age: 21.4+/-1.9 years; YA), old sedentary (n=15; age: 65.1+/-3.5 years; OS) and old active (n=17; age: 67.2+/-4.8 years; OA). Antioxidant activities and MDA level were assessed at rest and after an incremental exercise. There was no difference in resting antioxidant activities and lipid peroxidation between YS and OS. However, resting SOD and GR activities were higher in YA compared to OA (p<0.01 and p<0.05, respectively) and resting MDA level was higher in OA compared to YA (p<0.01). After exercise, a significant increase in SOD and GPX activities was observed in YS, YA and OA (p<0.01). Likewise, after exercise a significant increase of MDA level in YA, OS and OA (p<0.01) was observed. In addition, the comparison of YA to OA and YS to OA revealed similar antioxidant activities and lipid peroxidation between YS and OA, whereas antioxidant activities were higher in YA compared to OA. These data suggest that beneficial effects of regular physical activity in antioxidant defense and lipid peroxidation damage could be impaired by the aging process and that regular physical activity in older adults could maintain age related decreases in antioxidant defense. PMID- 29169190 TI - Measurement of Basal Serum Calcitonin for the Diagnosis of Medullary Thyroid Cancer. AB - Calcitonin (CT), a tumor marker for medullary thyroid cancer (MTC), can be stimulated with pentagastrin or calcium. Because of the unavailability of pentagastrin, basal CT measurement is frequently used for the preoperative diagnosis of MTC. The aim of the study was to define basal serum calcitonin (bCT) cut-off thresholds for diagnosing MTC. Within a retrospective analysis, 114 patients (51 males) were included fulfilling the criteria of an increased preoperative bCT level (>10 pg/ml) and the criteria of an available postoperative histology analysis. Based on a ROC plot analysis, the cut-off values for the diagnosis of MTC vs. non-malignancy (C cell hyperplasia and goiter) were identified. The most precise bCT thresholds for the identification of MTC were >=46 pg/ml for males (sensitivity: 93.6%, specificity: 95.0%, PPV: 97%, NPV: 90%) and >=35 pg/ml for females (sensitivity: 87.3%, specificity: 87.5%, PPV: 98%, NPV: 50%). Using these cut-offs, only 6% of male patients were not identified of having MTC, whereas 5% were false positive (having instead C cell hyperplasia). In females, the discrepancy was higher since 13% of female MTC patients were false negative by using the cut-off of >=35 pg/ml, and 13% had false positive results (suffering from C cell hyperplasia). Gender-specific bCT cut-offs for the identification of MTC vs. C cell hyperplasia and non-malignancy were defined, which can be used in clinical routine. In female patients, however, the accuracy is much lower compared to males. PMID- 29169191 TI - The Latest Developments of Functional Molecular Imaging in the Diagnosis of Primary Aldosteronism. AB - Differentiation of unilateral from bilateral aldosterone hypersecretion is the essential step in the clinical practice of primary aldosteronism (PA). Although adrenal venous sampling (AVS) has been established as the most standard test recommended by the guideline, its invasive and technically difficult nature has facilitated the approach to develop non-invasive functioning imaging as an alternative test. Compared to the conventional adrenocortical scintigraphy with cholesterol derivatives as tracer, the first-generation imaging, both of 11C MTO/PET and 123I-IMTO/SPECT/CT, the second-generation imaging, bind with high specificity and affinity to CYP11B enzymes and have advantages in shortening the time for obtaining specific images, reducing the radiation exposure to the patient, and resolution of the images. Because of very short half-life of 11C MTO, 123I-IMTO has a potential for a wider application than 11C-MTO. Sensitivity of identifying an adenoma smaller than 1 cm in diameter is still a common limitation of these new functional imaging methods. The new functional imaging could be supplementary to AVS in lateralization of PA when the results of AVS are not conclusive. To be a substitute for AVS, however, it should fulfill various conditions including high selectivity and binding affinity to CYP11B2, high sensitivity in detecting small adenoma, high resolution image, reduction of radiation exposure, and general versatility. Considering the potential number of patients, cost-effectiveness of the subtype testing in the clinical practice of PA could be one of the issues of the medical expenses. Thus, development of a new non-invasive functional imaging will have a significant impact on the clinical practice of PA and hypertension.

PMID- 29169195 TI - Wide-field piecemeal cold snare polypectomy of large sessile serrated polyps without a submucosal injection is safe. AB - : BACKGROUND AND STUDY AIMS : Large series suggest endoscopic mucosal resection is safe and effective for the removal of large (>= 10 mm) sessile serrated polyps (SSPs), but it exposes the patient to the risks of electrocautery, including delayed bleeding. We examined the feasibility and safety of piecemeal cold snare polypectomy (pCSP) for the resection of large SSPs. METHODS: Sequential large SSPs (10 - 35 mm) without endoscopic evidence of dysplasia referred over 12 months to a tertiary endoscopy center were considered for pCSP. A thin-wire snare was used in all cases. Submucosal injection was not performed. High definition imaging of the defect margin was used to ensure the absence of residual serrated tissue. Adverse events were assessed at 2 weeks and surveillance was planned for between 6 and 12 months. RESULTS: 41 SSPs were completely removed by pCSP in 34 patients. The median SSP size was 15 mm (interquartile range [IQR] 14.5 - 20 mm; range 10 - 35 mm). The median procedure duration was 4.5 minutes (IQR 1.4 - 6.3 minutes). There was no evidence of perforation or significant intraprocedural bleeding. At 2-week follow-up, there were no significant adverse events, including delayed bleeding and post polypectomy syndrome. First follow-up has been undertaken for 15 /41 lesions at a median of 6 months with no evidence of recurrence. CONCLUSIONS: There is potential for pCSP to become the standard of care for non-dysplastic large SSPs. This could reduce the burden of removing SSPs on patients and healthcare systems, particularly by avoidance of delayed bleeding. PMID- 29169196 TI - Peroral endoscopic myotomy in treatment-naive achalasia patients versus prior treatment failure cases. AB - BACKGROUND AND STUDY AIM: Peroral endoscopic myotomy (POEM) has emerged as an effective treatment modality for achalasia. Prior treatment may affect the outcomes of subsequent management. In this study, we aimed to compare the safety and efficacy of POEM in treatment-naive patients vs. those with prior treatment failure (PTF). PATIENTS AND METHODS: The data of consecutive patients with achalasia who underwent POEM at a single tertiary care center from January 2013 to November 2016 were analyzed retrospectively. A comparative analysis was performed between treatment-naive and PTF cases. Technical and clinical success, adverse events, and operative time for POEM were compared between the two groups. RESULTS: Overall, 502 patients with achalasia underwent POEM during the study period: 260 patients (51.8 %) in the treatment-naive group and 242 patients (48.2 %) in the PTF group. The mean operative time was significantly longer in the PTF group compared with the treatment-naive group (74.9 +/- 30.6 vs. 67.0 +/- 27.1 minutes; P = 0.002). On multivariate analysis, type of achalasia, dilated esophagus ( > 6 cm), disease duration, prior treatment, occurrence of adverse events, and type of knife used were significant predictors of operative time. Technical success (98.1 % vs. 97.1 %; P = 0.56) and clinical success (92.4 % vs. 92.5 %; P = 0.95) were comparable in the treatment-naive and PTF cases, respectively. Occurrence of gas-related events and mucosotomy were similar in both groups. Elevated DeMeester score was found in 17 /53 patients (32.1 %) in the PTF group and in 11 /44 patients (25.0 %) in the treatment-naive group (P = 0.50). CONCLUSION: POEM is safe and equally effective for treatment-naive patients and for those in whom prior treatment has failed. POEM should be considered the treatment of choice in patients in whom prior treatment has failed.

AB - BACKGROUND: Metformin was found to reduce circulating levels of pituitary hormones. OBJECTIVE: The purpose of this study was to assess whether sex determines the effect of metformin on lactotroph secretory function. METHODS: The study population included 25 women and 12 men with mildly elevated serum prolactin levels (25-75 ng/mL). Because of concomitant type 2 diabetes, all participants were treated with metformin (3 g daily). Plasma levels of glucose and lipids, HOMA1-IR, serum levels of prolactin, thyrotropin and free thyroid hormones, as well as Jostel's, SPINA-GT and SPINA-GD indices were assessed at baseline and at the end of metformin treatment. RESULTS: The study completed 24 women and 11 men. At baseline, there were no significant differences in circulating levels of glucose and lipids, insulin sensitivity, hormones, Jostel's, SPINA-GT and SPINA-GD indices between women and men. In both men and women, metformin reduced fasting glucose levels and HOMA1-IR. However, only in women metformin decreased elevated prolactin levels and this effect correlated with an improvement insulin sensitivity, as well as with the impact on SPINA-GT. CONCLUSIONS: The results of the study suggest that the effect of metformin on serum prolactin levels is sex-dependent.

AB - "Sense of coherence" (SOC) plays an essential role in the maintenance or recovery of health, according to the salutogenetic approach of Aaron Antonovsky. Empirical studies provide evidence of significant links between sense of coherence and different indicators of mental health. In the present study, the effectivity of an integrative counselling concept for the promotion of sense of coherence, reduction of mental distress and improvement of satisfaction with life was tested in a sample of 153 clients and patients. Correlations of SOC with mental distress and satisfaction with life and studies indicate a strong association. After psychosocial counselling according to the integrative ABCDE-model, significant pre-/post- changes with moderate to high effect sizes could be achieved. These findings bring important implications for the modifiability of the sense of coherence and provide evidence that the integrative ABCDE-model of psychosocial counseling might be effective. Correlations between ratings of the dimensions of the model and pre-/post changes are discussed.

AB - BACKGROUND: Internet addiction (IA) is associated with a high rate of co-morbid mental disorders, especially depression, anxiety disorders, ADHD and personality disorders and a considerable level of psychological strain. In terms of risk assessment, the present work investigates the current research literature on suicidal behavior and non-suicidal self-injurious behavior (NSSI). METHODS: We performed a systematic literature search in 14 databases on title and abstract level for the most common keywords for IA, NSSI and suicidality. After deduction of multiple items, 2334 articles remained. They were filtered per inclusion and exclusion criteria. We identified studies that examined the relationship between IA, NSSI and suicidality, which were assessed by validated psychometric instruments. This allowed a total of 15 studies to be included. RESULTS: The relationship between IA and suicidality was examined in 10 studies, four studies examined the relationship of IA, suicidality, and NSSI, and one study exclusively focused on IA and NSSHB. All studies showed higher prevalence for NSSI and respectively suicidality of the subjects with an IA compared to subjects without IA, with point prevalence varying considerably between 1.6-18.7%. DISCUSSION: The results of the included publications suggest that Internet dependency is associated with an increased rate of non-suicidal self-harming behavior and increased suicidality, with suicidal ideation being more closely related to IA than suicidal actions. In order to develop a better understanding of causal relationships between IA, NSSI and suicidality, further longitudinal studies are required. CONCLUSION: Against the background of the presented studies NSSHB and suicidality need to be explicitly addressed within the assessment and treatment of IA patients. PMID- 29169200 TI - [German Language Version and Validation of the Risk-Taking Behaviour Scale (RBS K) for High-Risk Sports]. AB - Background High-risk sports, particularly climbing, kayaking and extreme skiing, have become increasingly popular. The most widely used psychological survey instrument with regard to risk behaviour in sports is the Sensation Seeking Model, mostly assessed by the Sensation Seeking Scale (SSS-V). Until recently, the literature discussed risk behaviour solely through this model. However, this scale does not measure risk-taking behaviours. In contrast, the Risk-Taking Behaviour Scale (RBS-K) is a three-item scale that measures risk behaviour in high-risk sports. This study aimed to validate a German language version of the RBS-K. Methods The RBS-K was translated and back-translated between English and German. High-risk sports participants (n = 2399) completed the German version of the RBS-K. Of those participants, 820 completed the RBS-K in person as part of a field survey and 1579 participated in an online survey. To validate the questionnaire, the SSS-V, accident involvement, age and sex were evaluated. The RBS-K divides the sample into deliberate risk takers (mean + standard deviation) and risk-averse persons (mean - standard deviation). We tested for internal consistency and correlations with SSS-V, age, sex and accident involvement. Group differences were calculated between deliberate risk takers and risk-averse persons. Results For internal consistency, we obtained a Cronbach's alpha of 0.56 and a McDonald's omega of 0.63. Significant correlations were shown between RBS-K and SSS-V as well as age and sex. Compared to risk-averse persons (n = 643, 26.8 %), deliberate risk takers (n = 319, 13.3 %) scored significantly higher in sensation seeking, were significantly younger and primarily male and had a significantly higher accident involvement. Conclusion The RBS-K discriminates well for age, sex and accident involvement. Also, correlations between the RBS-K and the well-established SSS-V are acceptable. With regard to the results and its compact design, the scale seems to be well suited for field surveys. We discuss the relatively modest internal consistency in the context of the small number of items and the different dimensions of risk-taking.

PMID- 29169203 TI - Dissipation, residues and risk assessment of spirotetramat and its four metabolites in citrus and soil under field conditions by LC-MS/MS. AB - A modified Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method for the simultaneous determination of spirotetramat and its four metabolite residues in citrus, peel, pulp and soil was developed and validated by liquid chromatography with tandem mass spectrometry (LC-MS/MS). The samples were extracted with acetonitrile (1%, glacial acetic acid, v/v) and purified using primary secondary amine and octadecylsilane. The limit of detection was 0.01-0.13 mg/kg, whereas that of quantification was 0.02-0.40 mg/kg for spirotetramat and its metabolites. The average recoveries of spirotetramat, spirotetramat-enol, spirotetramat-mono-hydroxy, spirotetramat-enol-glucoside and spirotetramat ketohydroxy in all matrices were 73.33-107.91%, 75.93-114.85%, 76.44-100.78%, 71.46-103.19% and 73.08-105.27%, respectively, with relative standard deviations < 12.32%. The dissipation dynamics of spirotetramat in citrus and soil followed first-order kinetics, with half-lives of 2.3-8.5 days in the three sampling locations. The terminal residues of spirotetramat in four matrices at the three locations were measured below the 1.0 mg/kg maximum residue limit set by China, and residues were found to be concentrated on the peel. The risk assessment of citrus was evaluated using risk quotients. The risk quotient values were found to be significantly <1, suggesting that the risk to human health was negligible when using the recommended doses of spirotetramat in citrus. These results could provide guidance for the safe and proper application of spirotetramat in citrus in China.

PMID- 29169204 TI - Newborn genetic screening for spinal muscular atrophy in the UK: The views of the general population. AB - BACKGROUND: Spinal muscular atrophy (SMA) is an inherited neuromuscular disorder and a leading genetic cause of infant death worldwide. However, there is no routine screening program for SMA in the UK. Lack of treatments and the inability of screening tests to accurately predict disease severity are among the key reasons implementation of screening has faltered in the UK. With the recent release of the first therapy for SMA (Nusinersen), calls are being made for a reconsideration of this stance; however, very little is known about the views of the general public. METHODS: An online survey was administered to 232 individuals with no prior relationship with SMA to assess their attitudes toward a newborn screening program for it. Results are compared with previously gathered data on the views of SMA-affected families toward screening. RESULTS: Eighty-four percent of participants were in favor of newborn screening. Key reasons for support were a belief that it would lead to better healthcare and life expectancy for affected infants and facilitate informed decision-making for future pregnancies. Key reasons for nonsupport were a belief in the potential for significant negative impact on the family unit in terms of bonding and stress. CONCLUSIONS: Public acceptability is a key component in the evaluation of any potential screening program in the UK. This study demonstrates that newborn screening for SMA is viewed largely positively by people unfamiliar with the condition. The importance of early identification overrode all other social and ethical concerns about screening for the majority of participants.

AB - Mang-Guo-Zhi-Ke tablets (MGZKTs) is an effective Chinese patent medicine. It contains mango leaf extract as the main raw material and the antihistamine drug, chlorpheniramine maleate is included in the formulation. However, its pharmacokinetic effect is rarely reported. A highly sensitive, reliable and rapid high-throughput method using ultra-high-performance liquid chromatography with tandem mass spectrometry (UHPLC-MS/MS) was used to simultaneously determine kaempferol, quercetin, mangiferin, p-hydroxybenzoic acid, gallic acid and chlorpheniramine maleate in rat plasma after oral administration of MGZKTs. The method was successfully developed and fully validated to investigate the pharmacokinetics of MGZKTs. Chloramphenicol and clarithromycin were used as internal standards (IS). A practicable protein precipitation procedure with methanol was adopted for sample preparation. The samples were separated on an Acquity UHPLC Syncronis C18 column (100 * 2.1 mm, 1.7 MUm) using 0.1% formic acid acetonitrile as the mobile phase. The flow rate was set at 0.4 mL/min. The obtained calibration curves were linear in the concentration range of ~1-1000 ng/mL for plasma (r > 0.99). Method validation results met the criteria reported in the US Food and Drug Administration guidelines. Quercetin, p-hydroxybenzoic acid and kaempferol were absorbed rapidly and reached the peak concentration between 0.16 and 0.25 h. This validated that the UHPLC-MS/MS method was successfully applied to study the pharmacokinetic parameters of the six compounds in rat plasma after oral administration of MGZKTs. This evidence will be useful for the clinical rational use of Mang-Guo-Zhi-Ke tablets. PMID- 29169212 TI - Complications of CO2 insufflation during endoscopic vein harvesting.

AB - Aglycon protopanaxatriol (APPT) has valuable pharmacological effects such as memory enhancement and tumor inhibition. beta-Glycosidase from the hyperthermophilic bacterium Dictyoglomus turgidum (DT-bgl) hydrolyzes the glucose residues linked to APPT, but not other glycoside residues. beta-Glycosidase from the hyperthermophilic bacterium Pyrococcus furiosus (PF-bgl) hydrolyzes the outer sugar at C-6 but not the inner glucose at C-6 or the glucose at C-20. Thus, the combined use of DT-bgl and PF-bgl is expected to increase the biotransformation of PPT-type ginsenosides to APPT. We optimized the ratio of PF-bgl to DT-bgl, the concentrations of substrate and enzyme, and the reaction time to increase the biotransformation of ginsenoside Re and PPT-type ginsenosides in Panax ginseng leaf extract to APPT. DT-bgl combined with PF-bgl converted 1.0 mg/ml PPT-type ginsenosides in ginseng leaf extract to 0.58 mg/ml APPT without other ginsenosides, with a molar conversion of 100%. We achieved the complete biotransformation of ginsenoside Re and PPT-type ginsenosides in ginseng leaf extract to APPT by the combined use of two beta-glycosidases, suggesting that discarded ginseng leaves can be used as a source of the valuable ginsenoside APPT. To the best of our knowledge, this is the first quantitative production of APPT using ginsenoside Re, and we report the highest concentration and productivity of APPT from ginseng extract to date. PMID- 29169219 TI - Genome Analysis of Naphthalene-Degrading Pseudomonas sp. AS1 Harboring the Megaplasmid pAS1. AB - Polycyclic aromatic hydrocarbons (PAHs), including naphthalene, are widely distributed in nature. Naphthalene has been regarded as a model PAH compound for investigating the mechanisms of bacterial PAH biodegradation. Pseudomonas sp. AS1 isolated from an arsenic-contaminated site is capable of growing on various aromatic compounds such as naphthalene, salicylate, and catechol, but not on gentisate. The genome of strain AS1 consists of a 6,126,864 bp circular chromosome and the 81,841 bp circular plasmid pAS1. Pseudomonas sp. AS1 has multiple dioxygenases and related enzymes involved in the degradation of aromatic compounds, which might contribute to the metabolic versatility of this isolate. The pAS1 plasmid exhibits extremely high similarity in size and sequences to the well-known naphthalene-degrading plasmid pDTG1 in Pseudomonas putida strain NCIB 9816-4. Two gene clusters involved in the naphthalene degradation pathway were identified on pAS1. The expression of several nah genes on the plasmid was upregulated by more than 2-fold when naphthalene was used as a sole carbon source. Strains have been isolated at different times and places with different characteristics, but similar genes involved in the degradation of aromatic compounds have been identified on their plasmids, which suggests that the transmissibility of the plasmids might play an important role in the adaptation of the microorganisms to mineralize the compounds. PMID- 29169218 TI - Laccase Fermentation of Clove Extract Increases Content of Dehydrodieugenol, Which Has Neuroprotective Activity against Glutamate Toxicity in HT22 Cells. AB - Enzyme fermentation is a type of food processing technique generally used to improve the biological activities of food and herbal medicines. In this study, a Syzygii Flos (clove) extract was fermented using laccase derived from Trametes versicolor (LTV). The fermented clove extract showed greater neuroprotective effects against glutamate toxicity on HT22 than the non-fermented extract did. HPLC analysis revealed that the eugenol (1) and dehydrodieugenol (2) contents had decreased and increased, respectively, after fermentation. The content of 2 peaked at 1 h after fermentation to 103.50 +/- 8.20 mg/gex (not detected at zero time), while that of 1 decreased to 79.54 +/- 4.77 mg/gex (185.41 +/- 10.16 mg/gex at zero time). Compound 2 demonstrated promising HT22 neuroprotective properties with inhibition of Ca2+ influx, the overproduction of intracellular reactive oxygen species, and lipid peroxidation. In addition, LTV showed the best fermentation efficacy compared with laccases derived from Pleurotus ostreatus and Rhus vernicifera. PMID- 29169220 TI - Fermented Soymilk Alleviates Lipid Accumulation by Inhibition of SREBP-1 and Activation of NRF-2 in the Hepatocellular Steatosis Model. AB - Ingredients of soy and fermented soy products have been widely utilized as food supplements for health-enhancing properties. The aim of this study was to evaluate the effects of fermented soymilk (FSM) and soymilk (SM) on free fatty acid-induced lipogenesis in the hepatocellular steatosis model. HepG2 cells were incubated with palmitic acid (PA) for 24 h to induce lipogenesis and accumulation of intracellular lipid contents. The PA-treated cells were co-incubated with FSM, SM, genistein, and estrogen, respectively. Lipid accumulation in the PA-treated HpG2 cells was significantly decreased by co-incubation with FSM. Treatment of HepG2 cells with PA combined with genistein or estrogen significantly increased the expression of SREBP-1. However, FSM co-incubation significantly attenuated SREBP-1 expression in the PA-treated HepG2 cells; in addition, expression of NRF 2 and phosphorylation of ERK were significantly increased in the PA and FSM co incubated cells. PA-induced ROS production was significantly reduced by FSM and SM. Our results suggested that the bioactive components of FSM could protect hepatocytes against the lipid accumulation and ROS production induced by free fatty acids. These effects may be mediated by the inhibition of SREBP-1 and the activation of NRF-2 via the ERK pathway in HepG2 cells. PMID- 29169221 TI - Biochemical Characterization of a Novel GH86 beta-Agarase Producing Neoagarohexaose from Gayadomonas joobiniege G7. AB - A novel beta-agarase, AgaJ5, was identified from an agar-degrading marine bacterium, Gayadomonas joobiniege G7. It belongs to the glycoside hydrolase family 86 and is composed of 805 amino acids with a 30-amino-acid signal peptide. Zymogram analysis showed that purified AgaJ5 has agarase activity. The optimum temperature and pH for AgaJ5 activity were determined to be 30 degrees C and 4.5, respectively. AgaJ5 was an acidic beta-agarase that had strong activity at a narrow pH range of 4.5-5.5, and was a cold-adapted enzyme, retaining 40% of enzymatic activity at 10 degrees C. AgaJ5 required monovalent ions such as Na+ and K+ for its maximum activity, but its activity was severely inhibited by several metal ions. The Km and Vmax of AgaJ5 for agarose were 8.9 mg/ml and 188.6 U/mg, respectively. Notably, thin-layer chromatography, mass spectrometry, and agarose-liquefication analyses revealed that AgaJ5 was an endo-type beta-agarase producing neoagarohexaose as the final main product of agarose hydrolysis. Therefore, these results suggest that AgaJ5 from G. joobiniege G7 is a novel endo type neoagarohexaose-producing beta-agarase having specific biochemical features that may be useful for industrial applications. PMID- 29169222 TI - Metagenomic Approach to Identifying Foodborne Pathogens on Chinese Cabbage. AB - Foodborne illness represents a major threat to public health and is frequently attributed to pathogenic microorganisms on fresh produce. Recurrent outbreaks often come from vegetables that are grown close to or within the ground. Therefore, the first step to understanding the public health risk of microorganisms on fresh vegetables is to identify and describe microbial communities. We investigated the phyllospheres on Chinese cabbage (Brassica rapa subsp. pekinensis, N = 54). 16S rRNA gene amplicon sequencing targeting the V5-V6 region of 16S rRNA genes was conducted by employing the Illumina MiSeq system. Sequence quality was assessed, and phylogenetic assessments were performed using the RDP classifier implemented in QIIME with a bootstrap cutoff of 80%. Principal coordinate analysis was performed using a weighted Fast UniFrac matrix. The average number of sequence reads generated per sample was 34,584. At the phylum level, bacterial communities were composed primarily of Proteobacteria and Bacteroidetes. The most abundant genera on Chinese cabbages were Chryseobacterium, Aurantimonadaceae_g, Sphingomonas, and Pseudomonas. Diverse potential pathogens, such as Pantoea, Erwinia, Klebsiella, Yersinia, Bacillus, Staphylococcus, Salmonella, and Clostridium were also detected from the samples. Although further epidemiological studies will be required to determine whether the detected potential pathogens are associated with foodborne illness, our results imply that a metagenomic approach can be used to detect pathogenic bacteria on fresh vegetables. PMID- 29169223 TI - Comparison of PFGE, IS6110-RFLP, and 24-Locus MIRU-VNTR for Molecular Epidemiologic Typing of Mycobacterium tuberculosis Isolates with Known Epidemic Connections. AB - Two molecular epidemiologic methods, IS6110 restriction fragment length polymorphism (IS6110-RFLP) and 24-locus mycobacterial interspersed repetitive unit-variable-number tandem repeat (MIRU-VNTR), are used worldwide in studies of Mycobacterium tuberculosis (MTB). Conversely, because of its poor resolution, pulsed-field gel electrophoresis (PFGE) is not widely used for MTB. In this study, we improved the 24-locus MIRU-VNTR and PFGE protocols and compared the effectiveness of these approaches for the molecular typing of MTB using 75 clinical isolates obtained from a cohort investigation of high-risk populations infected with MTB. The 24-locus MIRU-VNTR method demonstrated superior discriminatory ability, followed by PFGE and IS6110-RFLP. Next, we analyzed six isolates with clear epidemiologic connections; that is, isolates from patients who attended the same school. IS6110-RFLP and PFGE identified these samples as the same type. By contrast, according to MIRU-VNTR, two isolates differed from four other isolates at one locus each; one isolate was identified as Mtub29 and the other as QUB-26. In summary, the 24-locus MIRU-VNTR assay was the most useful molecular typing method among the three methods investigated due to its discriminatory power, short time required, and availability as an epidemiologic investigation tool. PFGE was the second-best method. Compared with the other loci assessed in the 24-locus MIRU-VNTR assay, the Mtub29 and QUB-26 loci appeared to exhibit greater variability during transmission. PMID- 29169224 TI - Epigenetic Control of Oxidative Stresses by Histone Acetyltransferases in Candida albicans. AB - Candida albicans is a major pathogenic fungus in humans, and meets at first the innate immune cells, such as macrophages, in its host. One important strategy of the host cell to kill C. albicans is to produce reactive oxygen species (ROS) by the macrophages. In response to ROS produced by the macrophages, C. albicans operates its defense mechanisms against them by expressing its oxidative stress response genes. Although there have been many research studies explaining the specific transcription factors and the expression of the oxidative stress genes in C. albicans, the regulation of the oxidative stress genes by chromatin structure is little known. Epigenetic regulation by the chromatin structure is very important for the regulation of eukaryotic gene expression, including the chromatin structure dynamics by histone modifications. Among various histone modifications, histone acetylation is reported for its direct relationship to the regulation of gene expression. Recent studies reported that histone acetyltransferases regulate genes to respond to the oxidative stress in C. albicans. In this review, we introduce all histone acetyltransferases that C. albicans contains and some papers that explain how histone acetyltransferases participate in the oxidative stress response in C. albicans. PMID- 29169225 TI - Comparison of the effects of isoflurane versus propofol-remifentanil anesthesia on oxygen delivery during thoracoscopic lung lobectomy with one-lung ventilation in dogs. AB - This study compared effects of isoflurane inhalation (ISO) and propofol remifentanil combined total intravenous anesthesia (TIVA) on oxygenation during thoracoscopic lung lobectomy with 30-min one-lung ventilation (1LV). Thoracoscopic right middle lung lobectomy was performed in ten dogs divided into ISO and TIVA groups, and cardiopulmonary parameters were measured with blood gas analysis. Throughout the study, isoflurane was inhaled up to 1.5%, and the infusion rates of propofol and remifentanil were 0.2 to 0.4 mg/kg/min and 6 to 11 ug/kg/h, respectively. Cardiac index was not affected in the ISO group, but it increased during 1LV in the TIVA group. There were significant alterations in arterial oxygen pressure, arterial oxygen saturation, oxygen content, and shunt fraction associated with 1LV in each group. However, oxygen delivery did not decrease significantly due to open chest condition, 1LV, or surgical maneuver in either group, rather it increased during 1LV in the TIVA group. All parameters showed no significant difference between groups. Pulmonary vascular resistant index was unaffected in both groups, and there was no difference between groups except in re-ventilation phase. Accordingly, the effect of both anesthetic regimens on oxygenation was not different between groups and can be used with short-term 1LV for thoracoscopic lung lobectomy in dogs. PMID- 29169226 TI - Cytological endometritis in dairy cows: diagnostic threshold, risk factors, and impact on reproductive performance. AB - We determined the threshold proportion of polymorphonuclear leukocytes (PMNs) for a diagnosis of cytological endometritis (CEM), the risk factors for this condition, and its impact on reproductive performance in dairy cows. Uterine cytology was performed on 407 Holstein cows 4 weeks postpartum to determine the proportions of endometrial cells and PMNs. A receiver operator characteristics curve was used to determine the threshold above which the PMN proportion affected the likelihood of cows conceiving by 200 days postpartum. The optimal threshold was >= 14% PMN (sensitivity, 31.3%; specificity, 81.7%; p < 0.05). The farm identity, retained placenta (odds ratio [OR] = 1.87), and septicemic metritis (OR = 3.07) were risk factors for CEM (p < 0.05). Cows with CEM were less likely to resume cyclicity (OR = 0.58) and to conceive by 200 days postpartum (hazard ratio = 0.58). Cows with CEM tended (p < 0.1) to be less likely to become pregnant after their first insemination (OR = 0.65) and to require a greater number of inseminations per conception (2.3 vs. 2.2). In conclusion, a PMN threshold of 14% defined the presence of CEM at 4 weeks postpartum. The farm, retained placenta, and septicemic metritis were risk factors for CEM, which reduces subsequent reproductive performance. PMID- 29169227 TI - Korean red ginseng excitation of paraventricular nucleus neurons via non-N-methyl D-aspartate glutamate receptor activation in mice. AB - It has been reported that Korean red ginseng (KRG), a valuable and important traditional medicine, has varied effects on the central nervous system, suggesting its activities are complicated. The paraventricular nucleus (PVN) neurons of the hypothalamus has a critical role in stress responses and hormone secretions. Although the action mechanisms of KRG on various cells and systems have been reported, the direct membrane effects of KRG on PVN neurons have not been fully described. In this study, the direct membrane effects of KRG on PVN neuronal activity were investigated by using a perforated patch-clamp in ICR mice. In gramicidin perforated patch-clamp mode, KRG extract (KRGE) induced repeatable depolarization followed by hyperpolarization of PVN neurons. The KRGE induced responses were concentration- dependent and persisted in the presence of tetrodotoxin, a voltage sensitive Na+ channel blocker. The KRGE-induced responses were suppressed by 6-cyano-7-nitroquinoxaline-2,3-dione (10 MUM), a non-N-methyl D-aspartate (NMDA) glutamate receptor antagonist, but not by picrotoxin, a type A gamma-aminobutyric acid receptor antagonist. The results indicate that KRG activates non-NMDA glutamate receptors of PVN neurons in mice, suggesting that KRG may be a candidate for use in regulation of stress responses by controlling autonomic nervous system and hormone secretion. PMID- 29169228 TI - Control of type O foot-and-mouth disease by vaccination in Korea, 2014-2015. AB - On December 3, 2014, a type O foot-and-mouth disease (FMD) outbreak began in Korea. Although vaccinations were administered, FMD cases increased steadily for five months, and reached 185 cases by April 2015. Most of the affected animals were pigs, which are vulnerable to vaccination. The FMD virus belonged to the South-East Asia (SEA) topotype that had been observed three times in Korea between April 2010 and July 2014. However, the FMD virus isolated in December 2014 had a unique feature; that is, partial deletion of the 5' non-coding region, a deletion not seen in previous SEA topotype isolates identified in Korea. We conclude that this outbreak included the introduction of a new FMD strain to Korea, and that Korea was now affected by genetically similar FMD virus strains that are related to those from neighboring countries. PMID- 29169229 TI - Novel vertebral computed tomography indices in normal and spinal disorder dogs. AB - This study was carried out to derive and evaluate reference computed tomography (CT)-based indices for normal canine spine. CT and magnetic resonance images were acquired from 12 clinically normal Beagle dogs (normal group) and 50 dogs with 56 spinal disorders (patient group). Image acquisition regions were cervical spine (C2-T1), thoracic spine (T1-T13), and lumbar spine (L1-L7). Measured indices were: the ratios of width to height of the spinal cord including the dura matter (CR) and of the vertebral foramen (FR), and the ratio of the cross-sectional area of the spinal cord to that of the vertebral foramen (CFAR). Reliability analysis was performed to evaluate intermodality agreement. Student's t-tests and receiver operating characteristic curves were used to discriminate the normal and patient groups on CT. Intermodality agreements of the normal and patient groups were acceptable to excellent. The highest discriminating levels of CR at the vertebral body level and the intervertebral disc space level were 1.25 or more and 1.44 or more, respectively. FR and CFAR had the highest discriminating level at the cervical region. This report presents quantitative information on canine spinal morphometry; the obtained indices may be helpful for CT screening of dogs with spinal disorders. PMID- 29169230 TI - Ultrasonographic features of pure ductal carcinoma in situ of the breast: correlations with pathologic features and biological markers. AB - PURPOSE: The purpose of this study was to evaluate the ultrasonographic features of pure ductal carcinoma in situ (DCIS) of the breast and to evaluate the correlations of ultrasonographic features with pathologic and biological features. METHODS: A total of 141 lesions in 138 women with pure DCIS who underwent preoperative breast ultrasonography were retrospectively reviewed. Ultrasonographic features were analyzed using the American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) ultrasonography lexicon and the diagnostic criteria of the Japan Society of Ultrasonics in Medicine. Pathologic features including the nuclear grade and presence of comedonecrosis were evaluated. Biological markers including estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) status, as well as the Ki-67 index, were recorded. Ultrasonographic features were compared with pathologic findings and biological markers using the chi-square test. P-values of <0.05 were considered to indicate statistical significance. RESULTS: Of the 141 lesions, 75 (53.2%) were mass lesions, 26 (39.7%) were non-mass lesions, and 10 (7.1%) were not visible. The most common feature of the mass pattern was a mass with irregular shape (32.6%), an indistinct margin (27.7%), and hypoechogenicity (37.6%). Microcalcifications were observed in 48 cases (36.6%) as an associated feature. Calcifications outside of a mass were more common than calcifications within a mass. Ultrasonographic microcalcifications and ductal changes were frequently observed in non-mass lesions. Ultrasonographic non-mass lesions were associated with high-grade DCIS (P=0.004) and the presence of comedonecrosis (P=0.006), and microcalcifications were significantly associated with high-grade DCIS, the presence of comedonecrosis, an elevated Ki-67 index (P<0.001 for all), and HER2 positivity (P=0.003). CONCLUSION: The most common ultrasonographic feature of pure DCIS was an irregular, hypoechoic mass with an indistinct margin. Ultrasonographic microcalcifications and ductal changes were more frequent in non mass lesions, which were correlated with poor prognostic factors, such as a high nuclear grade, comedonecrosis, HER2 positivity, and an elevated Ki-67 index.

AB - Ultrasound (US)-guided breast biopsy has become the main method for diagnosing breast pathology, and it has a high diagnostic accuracy, approaching that of open surgical biopsy. However, methods for confirming adequate lesion retrieval after US-guided biopsy are relatively limited and false-negative results are unavoidable. Determining imaging-pathology concordance after US-guided biopsy is essential for validating the biopsy result and providing appropriate management. In this review article, we briefly present the results of US-guided breast biopsy; describe general aspects to consider when establishing imaging-pathology concordance; and review the various categories of imaging-pathology correlations and corresponding management strategies. PMID- 29169232 TI - Microcystic Stromal Tumor of Testicle: First Case Report and Literature Review. AB - Microcystic stromal tumor (MCST) is a rare subtype of sex cord-stromal neoplasm. Tumors from all 31 previously reported cases were located in the ovary. Herein, we present a unique case of a right-side testicular tumor in a 33-year-old Chinese male. The tumor is composed of predominantly lobulated cellular nodules separated by hyalinized fibrous stroma and they expressed CD10, beta-catenin (nuclear), and cyclin D1. Molecular analysis identified a point mutation (c.110C>G) in exon 3 of CTNNB1. The histopathological features, immunohistochemistry profiles, and molecular analysis of this tumor were consistent with MCST of the ovary. Therefore, a diagnosis of MCST of the right testicle was determined. To the best of our knowledge, this is the first case of MCST occurring in the testicles. The study may provide new insights to the tumor biology of MCST and a better understanding of this rare entity. PMID- 29169234 TI - Correction of the author name.

AB - PURPOSE: The purpose of this study was to investigate the effect of smoking habit change on the risk of cancer. Materials and Methods: From the Korean National Health Insurance Service database, we determined the change in smoking habit between the first (2002 and 2003) and second (2004 and 2005) health examination periods. A total of 143,071 men were categorized into baseline heavy (>= 20 cigarettes per day), moderate (10-19 cigarettes per day), light (< 10 cigarettes per day) smokers, quitters, and never smokers, after which the change in smoking status was determined during the second health examination. The participants were then followed up from 2006 to 2013 for all cancer, smoking related cancer, and lung cancer. RESULTS: Compared to heavy continual smokers, heavy smokers who quit had reduced risk of smoking related cancer (hazard ratio [HR], 0.74; 95% confidence interval [CI], 0.56 to 0.97) and tended to have reduced risk of all cancer (HR, 0.87; 95% CI, 0.75 to 1.00). Moderate smokers who reduced the amount of smoking to light levels had decreased risk of all cancer (HR, 0.82; 95% CI, 0.72 to 0.94), smoking related cancer (HR, 0.74; 95% CI, 0.59 to 0.93), and lung cancer (HR, 0.55; 95% CI, 0.38 to 0.79) compared to heavy continual smokers. CONCLUSION: Smoking reduction decreases the risk of all cancer, smoking related cancer, and lung cancer. While smoking cessation should be the treatment of choice for smokers, smoking reduction may serve as an alternative strategy for those who cannot quit. PMID- 29169235 TI - Hypermagnesuria in Humans Following Acute Intravenous Administration of Digoxin. AB - BACKGROUND: Hypomagnesemia is a known predisposing condition for the appearance of digitalis toxicity. The detection of a genetic form of Mg urinary wasting with hypomagnesemia being caused by a mutation in the gamma subunit (FXYD2) of the Na,K-ATPase, the pharmacological target of Digoxin, prompted us to investigate whether Digoxin administration increases urinary Mg excretion. METHODS: Two groups of subjects, with rapid atrial fibrillation, received intravenous Digoxin (n = 9) or verapamil (n = 8), for heart rate control. During the following 4 h, blood and urinary creatinine, sodium, potassium, calcium, and magnesium levels were determined, and fractional excretion (Fex) values for Na, K, Ca, and Mg were calculated. RESULTS: In the Digoxin group, at 60 min Fex Mg rose from 3.07 +/- 1.21 to 7.58 +/- 2.51% (an increase of 269 +/- 107% of baseline, p < 0.001), and at 240 min to 6.05 +/- 2.30% (204 +/- 56% of baseline, p < 0.01). No significant change was observed for Fex Na, Fex K, and Fex Ca. A striking correlation was found between individual values of Fex Mg and serum Digoxin concentration (r = 0.678, p < 0.0001). No significant correlation was found between Fex Na or Fex K and serum Digoxin. A correlation of borderline significance was found between Fex Ca and serum Digoxin (r = 0.349, p = 0.073). CONCLUSIONS: The hypermagnesuric effect of acute Digoxin treatment is reminiscent of the effect of the missense mutation in FXYD2, which assumes that FXYD2 is a positive regulator of Na,K ATPase in the distal convoluted tubule (DCT). The borderline calciuric effect of Digoxin may point to an additional site of action, more proximal to the DCT, that is, the thick ascending limb. PMID- 29169236 TI - Aerosol Emissions from Great Lakes Harmful Algal Blooms. AB - In freshwater lakes, harmful algal blooms (HABs) of Cyanobacteria (blue-green algae) produce toxins that impact human health. However, little is known about the lake spray aerosol (LSA) produced from wave-breaking in freshwater HABs. In this study, LSA were produced in the laboratory from freshwater samples collected from Lake Michigan and Lake Erie during HAB and nonbloom conditions. The incorporation of biological material within the individual HAB-influenced LSA particles was examined by single-particle mass spectrometry, scanning electron microscopy with energy-dispersive X-ray spectroscopy, and fluorescence microscopy. Freshwater with higher blue-green algae content produced higher number fractions of individual LSA particles that contained biological material, showing that organic molecules of biological origin are incorporated in LSA from HABs. The number fraction of individual LSA particles containing biological material also increased with particle diameter (greater than 0.5 MUm), a size dependence that is consistent with previous studies of sea spray aerosol impacted by phytoplankton blooms. Similar to sea spray aerosol, organic carbon markers were most frequently observed in individual LSA particles less than 0.5 MUm in diameter. Understanding the transfer of biological material from freshwater to the atmosphere via LSA is crucial for determining health and climate effects of HABs. PMID- 29169237 TI - Janus Colloids toward Interfacial Engineering. AB - Janus colloids are functional particles consisting of two surfaces (or internal materials) with distinct physical or chemical properties in the same particle. Owing to their amphiphilic nature, Janus colloids composed of both hydrophilic and hydrophobic faces provide a powerful tool to generate functional surfaces and to manipulate the properties of interfaces. Amphiphilic Janus colloids have shown promising applications as particulate surfactants in oil/water separation, as interfacial compatibilizers in polymer blends, and as assembly blocks in robust coatings with unique wettability. In this Feature Article, we summarize recent advances in engineering interfaces by using Janus colloids. PMID- 29169238 TI - Electronic and Optical Properties of Pristine and Vertical and Lateral Heterostructures of Janus MoSSe and WSSe. AB - On the basis of electron-electron self-energy corrections, quasiparticle band structures of Janus MoSSe and WSSe are identified, and the excitonic effects are demonstrated to play a dominate role in the optical response. Combining together MoSSe and WSSe monolayers to form vertical heterostructures (VHTs) and lateral heterostructures (LHTs) rarely leads to a simple arithmetic sum of their properties, giving rise to novel and unexpected behaviors. In particular, Rashba polarization can be enhanced in VHTs due to improved out-of-plane electric polarity. In the case of LHTs, photoresponse and absorption coefficients show optical activity in a wide visible light range. It is of interest that both VHTs and LHTs reveal type-II band alignment, enabling the separation of excitons. Besides, grain boundaries (GBs) of large angle (60 degrees ) in Janus MoSSe due to chalcogen effects behave as one-dimensional (1D) metallic quantum wires, suggesting the possible formation of 1D electron or hole gas in such electronic heterostructures. PMID- 29169239 TI - Modification of Transition-Metal Redox by Interstitial Water in Hexacyanometalate Electrodes for Sodium-Ion Batteries. AB - A sodium-ion battery (SIB) solution is attractive for grid-scale electrical energy storage. Low-cost hexacyanometalate is a promising electrode material for SIBs because of its easy synthesis and open framework. Most hexacyanometalate based SIBs work with aqueous electrolyte, and interstitial water in the material has been found to strongly affect the electrochemical profile, but the mechanism remains elusive. Here we provide a comparative study of the transition-metal redox in hexacyanometalate electrodes with and without interstitial water based on soft X-ray absorption spectroscopy and theoretical calculations. We found distinct transition-metal redox sequences in hydrated and anhydrated NaxMnFe(CN)6.zH2O. The Fe and Mn redox in hydrated electrodes are separated and are at different potentials, leading to two voltage plateaus. On the contrary, mixed Fe and Mn redox in the same potential range is found in the anhydrated system. This work reveals for the first time how transition-metal redox in batteries is strongly affected by interstitial molecules that are seemingly spectators. The results suggest a fundamental mechanism based on three competing factors that determine the transition-metal redox potentials. Because most hexacyanometalate electrodes contain water, this work directly reveals the mechanism of how interstitial molecules could define the electrochemical profile, especially for electrodes based on transition-metal redox with well-defined spin states. PMID- 29169240 TI - Differential Reinforcement of Other Behaviors to Treat Challenging Behaviors Among Children With Autism: A Systematic and Quality Review. AB - This review summarizes the literature regarding differential reinforcement of other behaviors (DRO) to treat challenging behavior among children with autism spectrum disorder (ASD) and determines the quality of studies among the current literature according to the 2014 Council for Exceptional Children (CEC): Standards for Evidence-Based Practices in Special Education. Studies that focused on the use of DRO in the treatment of challenging behavior for individuals with ASD were included for systematic analysis. Forty-five studies were identified for inclusion in this review and were evaluated using the eight quality indicators described by the CEC. To the authors' knowledge, this is the only systematic review of the literature that evaluates DRO as an intervention for individuals diagnosed with ASD. Principle findings, practical recommendations, and areas of future research are discussed. PMID- 29169242 TI - Lag Schedules and Functional Communication Training: Persistence of Mands and Relapse of Problem Behavior. AB - We evaluated the effects of lag schedules of reinforcement and functional communication training (FCT) on mand variability and problem behavior in two children with autism spectrum disorder. Specifically, we implemented FCT with increasing lag schedules and compared its effects on problem behavior with baseline conditions. The results showed that both participants exhibited low rates of problem behavior during treatment relative to baseline during and following schedule thinning (up to a Lag 5 schedule arrangement). Variable and total mands remained high during schedule thinning. With one participant, variable manding persisted when the value of the lag schedule was reduced to zero. The current results are discussed in terms of implications for training multiple mand topographies during FCT for the potential prevention and/or mitigation of clinical relapse during challenges to treatment. PMID- 29169243 TI - Time Savings Using a Standardized Glucose Reporting System and Ambulatory Glucose Profile. AB - BACKGROUND: Diabetes care is predominately done at home by the patient. When clinics do not have a reliable, easy process for obtaining this patient data, clinical decisions must be made with incomplete verbal recall reports. Unused or inaccessible glucose data represent a large information gap affecting clinical decision making. This study's purpose was to design an optimized glucose device download system with a standardized report and to evaluate its efficiency. METHODS: Observations and evaluations of glucose data retrieval occurred at two clinics; an additional clinic utilized the optimized process doing only post process timings. Patients/families and clinicians were surveyed about their experiences with the system and the standardized report (AGP). The study was approved by all the sites' IRBs. RESULTS: Optimized systems saved staff at least 3 min per patient. Standardized AGP reports and an optimized data system made the work flow of glucose data easier to complete. The AGP report was preferred by patients, families, and clinicians. CONCLUSIONS: An optimized system takes advantage of patient lobby downtime to download glucose devices and ensures that diabetes clinical decisions are made utilizing all available data. Staff and patients liked the software lobby system and found it a valuable time-saving tool. PMID- 29169241 TI - Gut reactions: How the blood-brain barrier connects the microbiome and the brain. AB - A growing body of evidence indicates that the microbiome interacts with the central nervous system (CNS) and can regulate many of its functions. One mechanism for this interaction is at the level of the blood-brain barriers (BBBs). In this minireview, we examine the several ways the microbiome is known to interact with the CNS barriers. Bacteria can directly release factors into the systemic circulation or can translocate into blood. Once in the blood, the microbiome and its factors can alter peripheral immune cells to promote interactions with the BBB and ultimately with other elements of the neurovascular unit. Bacteria and their factors or cytokines and other immune-active substances released from peripheral sites under the influence of the microbiome can cross the BBB, alter BBB integrity, change BBB transport rates, or induce release of neuroimmune substances from the barrier cells. Metabolic products produced by the microbiome, such as short-chain fatty acids, can cross the BBB to affect brain function. Through these and other mechanisms, microbiome-BBB interactions can influence the course of diseases as illustrated by multiple sclerosis. Impact statement The connection between the gut microbiome and central nervous system (CNS) disease is not fully understood. Host immune systems are influenced by changes to the microbiota and offers new treatment strategies for CNS disease. Preclinical studies provide evidence of changes to the blood-brain barrier when animals are subject to experimental gut infection or when the animals lack a normal gut microbiome. The intestine also contains a barrier, and bacterial factors can translocate to the blood and interact with host immune cells. These metastatic bacterial factors can signal T-cells to become more CNS penetrant, thus providing a novel intervention for treating CNS disease. Studies in humans show the therapeutic effects of T-cell engineering for the treatment of leukemia, so perhaps a similar approach for CNS disease could prove effective. Future research should begin to define the bacterial species that can cause immune cells to differentiate and how these interactions vary amongst CNS disease models. PMID- 29169244 TI - Translation and Validation of the Toronto Pain Management Index, French-Canadian Version. AB - Background To provide effective pain management, nurses must have sufficient knowledge and adequate beliefs about pain management. In Quebec, however, nurses seem to be generally uninvolved in pain management, and there is little significant evidence shedding light on nurses' pain management knowledge and beliefs in postoperative settings. To perform such studies, a valid questionnaire in French to assess nurses' knowledge and beliefs is required. Some valid questionnaires are available in English, but none are available in French. Purpose This article describes the process of translation, adaptation, and preliminary validation of the Toronto Pain Management Index into French. Results For temporal stability of the Toronto Pain Management Index, French-Canadian version, the result of intraclass correlation coefficient for the total score of this questionnaire is 0.59 (CI: 0.44-0.72). Conclusion Following this process, the French version of this questionnaire has suitable face and content validity and can be used to evaluate nurses' knowledge and beliefs about pain management in postoperative settings. PMID- 29169245 TI - A systematic review of evidence for older adults' sedentary behavior and physical activity after hip fracture. AB - OBJECTIVE: To synthesize evidence on older adults' sedentary behavior and physical activity during rehabilitation and recovery for hip fracture (1) across the care continuum and (2) from clinical interventions. DESIGN: We conducted a systematic review of peer-reviewed publications using CINAHL, Embase, Ovid MEDLINE, PsycINFO, and SportDiscus (last search: 17 October 2017). STUDY SELECTION: We included studies that measured sedentary behavior and physical activity of older adults with hip fracture using activity monitors (e.g. accelerometers). We identified literature at Level 1 (title and abstract) and Level 2 (full text), and conducted forward and backward searches. We assessed observational studies' adherence to reporting guidelines and intervention studies' risk of bias. RESULTS: We included 14 studies (882 participants). Four studies reported sedentary behavior data, while all studies reported information on physical activity. Settings included hospital, rehabilitation centers, and the community. Nine studies were observational; five were experimental design. Older adults had excessive sedentary time (>10 hours/day) and low physical activity. Participants' average upright time differed across settings. During hospital stay, it ranged 16-52 minutes/day, while in the community, it ranged 51-261 minutes/day. Data from five interventions reported on physical activity change: two studies increased between 14 and 27 minutes/day. Another study reported participants accumulated 6994 steps/day at the end of the intervention, but for two other interventions, activity was below 5000 steps/day. CONCLUSION: Based on available evidence, older adults with hip fracture engage in prolonged sedentary behavior and have low levels of physical activity during rehabilitation and recovery. PMID- 29169246 TI - Children With Intellectual Disability and Hospice Utilization: The Moderating Effect of Residential Care. AB - BACKGROUND: Children with intellectual disability commonly lack access to pediatric hospice care services. Residential care may be a critical component in providing access to hospice care for children with intellectual disability. OBJECTIVE/HYPOTHESIS: This research tested whether residential care intensifies the relationship between intellectual disability and hospice utilization (ie, hospice enrollment, hospice length of stay), while controlling for demographic characteristics. METHODS: Multivariate regression analyses were conducted using 2008 to 2010 California Medicaid claims data. RESULTS: The odds of children with intellectual disability in residential care enrolling in hospice care were 3 times higher than their counterparts in their last year of life, when controlling for demographics. Residential care promoted hospice enrollment among children with intellectual disability. The interaction between intellectual disability and residential care was not related to hospice length of stay. Residential care did not attenuate or intensify the relationship between intellectual disability and hospice length of stay. CONCLUSIONS: The findings highlight the important role of residential care in facilitating hospice enrollment for children with intellectual disability. More research is needed to understand the capability of residential care staff to identify children with intellectual disability earlier in their end-of-life trajectory and initiate longer hospice length of stays. PMID- 29169247 TI - Palliative Care Consultation for Goals of Care and Future Acute Care Costs: A Propensity-Matched Study. AB - BACKGROUND: Hospitals are under increasing pressure to manage costs across multiple episodes of care. Most studies of the financial impact of palliative care have focused on costs during a single hospitalization. OBJECTIVE: To compare future acute health-care costs and utilization between patients who received inpatient palliative care consultation for goals of care (Palliative Care Service [PCS]) and a propensity-matched cohort of patients who did not receive palliative care consultation (non-PCS) in a single academic medical center. METHODS: Data were extracted from the hospital's electronic records for admissions and discharges between July 2014 and October 2016. A stratified propensity score matching was used to account for nonrandom assignment and potential inherent differences between PCS and non-PCS groups using variables of theoretical interest: age, gender, race, diagnosis, risk of mortality, and prior acute care costs. RESULTS: The analytical sample for this study included 41 363 patients (PCS = 1853; non-PCS = 39 510). Future acute care costs were significantly higher in the non-PCS group after propensity score matching (highest tier = US$15 654 vs US$8831; second highest tier = US$12 200 vs US$5496; P = .0001). The non-PCS group also had significantly higher future acute care utilization across all propensity tiers and outcomes including 30-day readmission ( P = .0001), number of future hospital days ( P = .0001), and number of future intensive care unit days ( P = .0001). CONCLUSION: Palliative care consultations for goals of care may decrease future health-care utilization with cost savings that persist into future hospitalizations. PMID- 29169248 TI - Quality of Life and Compassion Satisfaction in Clinicians: A Pilot Intervention Study for Reducing Compassion Fatigue. AB - BACKGROUND: Compassion fatigue (CF) is prevalent in healthcare professionals, particularly in those caring for chronic, acutely ill, and/or those patients who might be moving toward comfort care. Over time, CF can lead to burnout (BO) and secondary traumatic stress and an overall decrease in professional quality of life. In this pilot study, participants completed a resiliency program focused on education about CF and self-awareness of its individualized impact and were expected to develop ongoing self-care practices to prevent/address the untoward effects. METHODS: Healthcare professionals ( N = 15) participated in a formalized educational program consisting of three 90-minute educational sessions held 2 weeks apart. Preassessment and postintervention data were collected electronically in survey format. A postprogram evaluation was also offered. RESULTS: Upon completion of the program, participants noted an increase in compassion satisfaction (CS) and a small reduction in BO. Secondary traumatic stress remained unchanged. Feedback about the program was positive, and participants reported the impact on their clinical practice and life to be moderately high. At 6 months, over half of the participants continued to report positive impact on their personal/professional lives. CONCLUSION: While the small sample size of this pilot study limits the generalizability of the findings, there were positive effects for CS and BO in participants over time, indicating possible benefits of providing self-care education to healthcare providers. Additional research with a larger sample size is needed to address how healthcare providers might further benefit from resiliency education and interventions to improve professional quality of life. PMID- 29169249 TI - An intelligent detection method for high-field asymmetric waveform ion mobility spectrometry. AB - In conventional high-field asymmetric waveform ion mobility spectrometry signal acquisition, multi-cycle detection is time consuming and limits somewhat the technique's scope for rapid field detection. In this study, a novel intelligent detection approach has been developed in which a threshold was set on the relative error of alpha parameters, which can eliminate unnecessary time spent on detection. In this method, two full-spectrum scans were made in advance to obtain the estimated compensation voltage at different dispersion voltages, resulting in a narrowing down of the whole scan area to just the peak area(s) of interest. This intelligent detection method can reduce the detection time to 5-10% of that of the original full-spectrum scan in a single cycle. PMID- 29169250 TI - Clinical effects of cognitive impairment in patients with chronic obstructive pulmonary disease. AB - The aim of this study was to evaluate the clinical effects of cognitive impairment in patients with chronic obstructive pulmonary disease (COPD). A total of 91 patients with stable moderate to very severe COPD were included in this study. Cognitive functions of the patients were evaluated using the mini-mental state examination (MMSE) tool and clock-drawing test. The Brody's Instrumental Activities of Daily Living (IADL) Questionnaire; COPD assessment test (CAT); body mass index, airflow obstruction, dyspnea, and exercise capacity (BODE); and Charlson comorbidity index were assessed. The patients were divided into two groups as those who were diagnosed with cognitive impairment (group 1, n = 16) and those with normal cognitive functions (group 2, n = 75). Group 1 had a lower arterial partial pressure of oxygen , shorter 6-min walking distance, and higher arterial partial pressure of carbon dioxide (PaCO2) than group 2 ( p = 0.01, p = 0.024, p = 0.018, respectively). In group 1, the IADL score was lower, and CAT and BODE scores were higher than group 2 ( p = 0.002, p = 0.037, p = 0.012, respectively). When we considered all the patients, there was an independent correlation between the IADL score and MMSE score ( p = 0.03). This study revealed that COPD patients with cognitive impairment may have more hypoxemia and limited activities of daily living. PMID- 29169252 TI - Distinguishing Levels of Suicide Risk in Depressed Male Veterans: The Role of Internalizing and Externalizing Psychopathology as Measured by the MMPI-2-RF. AB - Suicide occurs at high rates among veterans, underscoring a need for improved identification of veterans at risk of engaging in suicidal behavior. Considering dimensions of psychopathology in the context of an ideation-to-action framework, the present study examined the utility of the Minnesota Multiphasic Personality Inventory-2-Restructured Form in distinguishing depressed, psychiatrically hospitalized male veterans ( N = 430) at varying levels of suicide risk. Analysis of variance and hierarchical logistic regression analyses indicated that internalizing scales differentiated depressed ideators ( n = 147) and depressed controls ( n = 143); and in line with expectations, both broad and narrowly focused externalizing scales provided incremental validity in distinguishing depressed attempters ( n = 140) from depressed ideators. Interactions between Suicidal/Death Ideation and externalizing scale scores were found to differentiate only depressed ideators from depressed controls. Clinical implications in the areas of suicide risk assessment and therapeutic interventions with suicidal veterans are discussed. PMID- 29169251 TI - Factors Associated With Meat Safety Knowledge and Practices Among Butchers of Ratnanagar Municipality, Chitwan, Nepal: A Cross-sectional Study. AB - Butchers have a huge role in prevention of meat-borne diseases and illness. Hence, this study was conducted to ascertain factors associated with meat hygiene among the butchers. A cross-sectional study was conducted among goat and poultry butchers. None of the butchers fall into "adequate" knowledge and "good" practice category. Butchers who had no side job other than butchering (adjusted odds ratio [aOR] = 3.04, CI = 1.11-8.33), had secondary or higher education (aOR = 3.17, CI = 2.60-14.72), greater workload (aOR = 5.45, CI = 1.01-29.57), and whose shop were closed shop (aOR = 3.33, CI = 1.10-10.38) were more likely to have fair knowledge. Butchers whose shop were temporarily constructed close shop (aOR = 3.07, CI = 1.04-9.06), permanently constructed close shop (aOR = 23.56, CI = 1.91 291.11), and whose ethnicity was Brahmin/Chhetri (aOR = 3.39, CI = 1.10-10.46) were more likely to have satisfactory practices. Despite regular handling of meat, butchers had lack of knowledge and practice on meat hygiene. PMID- 29169253 TI - Treatment of Elopement Without Blocking With a Child With Autism. AB - Elopement is a dangerous behavior common in children with autism spectrum disorder (ASD). Relative to other forms of problematic behavior, elopement has received little attention in both assessment and treatment. The current study entailed a functional analysis of elopement of one child with ASD, results of which suggested a partially automatic function. We then evaluated a differential reinforcement procedure, along with a rule, which successfully decreased elopement without the use of blocking. A changing-criterion design embedded within a withdrawal design was used to gradually increase the criterion for maintaining a close proximity to a therapist prior to being allowed to run. PMID- 29169254 TI - Risky wandering behaviors of persons with dementia predict family caregivers' health outcomes. AB - OBJECTIVES: To examine the relationships between dementia persons' risky wandering behaviors and family caregivers' physical and mental health. METHODS: A secondary analysis was conducted using the original cross-sectional data from180 dyads. The Risky Wandering and Adverse Outcome model assessed behaviors of eloping and getting lost outside the house for dementia persons. Data were analyzed using descriptive statistics, Pearson's correlation coefficient and hierarchical regressions. RESULTS: The mean age of caregivers was 56.01 years (SD = 13.8); 65% were female. Younger caregivers experienced greater physical fatigue and sleep disturbance. Presence of foreign helpers predicted a reduction in mental and physical fatigue of caregiver (beta = -0.186, p < .05; beta = 0.198, p < .05, respectively). Getting lost outside of the house influenced caregivers' mental fatigue (beta = 0-0.215, p < .05); eloping behavior influenced caregivers' sleep disturbance (beta = 0.231, p < .05). Care-receivers' activities of daily living affected caregivers' depressive symptoms (beta = -0.179, p < .05). CONCLUSIONS: Dementia family caregiver physical and mental health problems have distinct predictors. Employing the Risky Wandering and Adverse Outcome model could inform policy makers regarding long-term care resources to improve dementia care. PMID- 29169255 TI - A Standard-Setting Body for US Health Care Quality Measurement. PMID- 29169256 TI - Tolosa-Hunt Syndrome: Appraising the ICHD-3 beta diagnostic criteria. AB - Introduction The term Tolosa-Hunt Syndrome was first used more than half a century ago to describe painful ophthalmoplegia accompanied by cranial nerve palsies. In the decades since, its diagnostic criteria have evolved considerably. The beta version of the 3rd Edition of the International Classification of Headache Disorders narrows these criteria to require the demonstration of granulomatous inflammation on MRI or biopsy. We believe this may introduce challenges to accurate diagnosis. Discussion Requiring the demonstration of granulomatous inflammation for a diagnosis of Tolosa-Hunt Syndrome may introduce the potential for false negative and false positive diagnoses. Although the disorder presents secondary to granulomatous inflammation, MRI technology may not be able to identify it reliably, and biopsy is not always indicated for its symptomatology. Additionally, several cases have been reported of Tolosa-Hunt Syndrome diagnosed with MRI-confirmed granulomatous inflammation that later prove to be attributable to other pathologies. The emphasis on neuroimaging may therefore exclude some true Tolosa-Hunt Syndrome cases and include others resulting from other latent pathologies that are not visible on MRI. Conclusion We wish to offer several potential modifications to the International Classification of Headache Disorders guidelines for Tolosa-Hunt Syndrome, including making the demonstration of granulomatous inflammation on MRI or biopsy non-mandatory and lengthening patient follow-up to two years for cases in which MRI is unrevealing.

PMID- 29169258 TI - High-sensitivity cardiac troponin concentrations at emergency department presentation in females and males with an acute cardiac outcome. AB - Background There is interest in utilizing different cut-offs per sex for high sensitivity cardiac troponin I (hs-cTnI) but less so for high-sensitivity cardiac troponin T (hs-cTnT) for patient management in the acute setting. Our objective was to assess if differences in hs-cTn concentrations exist between males and females for an acute cardiac outcome following the presentation measurement in the emergency department. Methods An observational emergency department population with hs-cTn measurements (Roche Diagnostics and Abbott Diagnostics) at presentation with seven-day outcomes for a composite acute cardiac outcome (i.e. myocardial infarction, unstable angina, ventricular arrhythmia, heart failure or cardiovascular death) (ClinicalTrials.gov: NCT01994577). Receiver operating characteristic curve analyses were performed for each sex with both hs-cTn assays. Results In those patients who had a composite acute cardiac outcome ( n = 128 females; n = 145 males), there was no difference in hs-cTn concentrations between the sexes (median [IQR] female hs-cTnT = 35 ng/L [21-69] vs. male hs-cTnT = 38 ng/L [19-77], P = 0.95; and median [IQR] female hs-cTnI = 27 ng/L [12-75] vs. male hs-cTnI = 26 ng/L [12-85], P = 0.97]. There was also no difference in the area under the curve between the hs-cTn assays and between the sexes ( P > 0.10). Comparing hs-cTn concentrations in those patients with the composite outcome between the sexes <60 years and >=60 years of age also did not yield significant differences ( P > 0.70). Conclusions The concentrations and area under the curves of hs-cTnT and hs-cTnI at patient presentation in the emergency department for an acute composite cardiac outcome were similar between the sexes in this exploratory study.

AB - Both children and adults exhibit moderate conformity behaviors when facing group pressure. While some studies purport that children conform more with age, others have shown the opposite. The publicity of decision-making might be a major factor influencing the development of children's conformity behavior. In this study, we recruited 295 Chinese children aged 9-15 years. We observed no significant correlation between children's age and conformity behaviors when their answers were kept confidential. However, older children showed stronger conformity behaviors when their answers were made public. According to cultural evolutionary theory, with age, children find group acceptance and social recognition increasingly more important, which explains why older children are more likely to conform-namely, doing so has adaptive value. Further research should explore the cross-cultural coherence of this phenomenon and the genuine motivation behind children's conformity behaviors. Meanwhile, designing a more reliable and valid experiment would also be a fruitful direction. PMID- 29169264 TI - Adaptive Memory: Remembering Potential Mates. AB - According to the adaptive memory perspective, memory should function more efficiently in fitness-relevant domains. The current work explored whether there is a mnemonic tuning in a fundamental domain for human evolution: reproduction. In two experiments, female participants assessed how desirable potential male candidates (represented by a face and a short descriptor) would be in the context of a long-term mating relationship or in the context of a long-term work relationship. Then, after a short distractor task, participants performed a recognition task for the faces and a source memory task. Finally, they were asked to recall the descriptors presented during encoding. Experiment 1 used a between subjects design, whereas Experiment 2 employed a within-subject design. In both experiments, participants remembered the faces best when they were encoded in the mating condition. Also, in Experiment 1, source memory performance was better in the mating condition than in the working condition with the reverse being true for free recall of the descriptors. The latter difference was not observed in Experiment 2. These results suggest a potential mnemonic tuning for the faces of potential mate partners.

AB - One new formylated chalcone, 3'- formyl xanthohumol (1) was isolated from the EtOAc-soluble partition of the cones of Humulus lupulus, along with two other known chalcones, namely dehydrocycloxanthohumol (2) and xanthohumol (3). The structure of compound 1 was elucidated on the basis of its 1D, 2D NMR and MS data. The structures of the known compounds were identified by comparison of their spectroscopic data with those reported by the literatures. The isolates were tested for their protective effects on human umbilical vein endothelial cells (HUVECs) injured by angiotensin II (Ang II), all the three compounds protected against the cell injury at the concentration of 20 MUMU, and compound 3 showed the most potent activity by improving cell viability from 53.9 to 74.9%.

AB - The study presents an experimental verification of Wagner et al.'s relationship in microscale and proposes a modification of this relationship. For this purpose, 11 cubic specimens were microcomputed tomography scanned and mechanically tested with the displacement full-field measurements using a digital image correlation system. Then, numerical simulations of the compression tests were performed using a finite elements method. The Young's modulus distributions assigned to the finite elements models were calculated using both of Wagner et al.'s relationships: original and modified. Comparison of the experimental and numerical results indicated the accuracy of numerical solutions for both relationships.

AB - Cereal bars are nutritious food composed of several ingredients including dry raw and agglutinative ingredients. The objective of this study was to evaluate the effect of pear apple and date fibres, from cooked fruit co-product, addition on the physico-chemical textural and sensory properties of cereal bars. First, five formulations containing an amount of 10% of co-products and commercial fibre, used as a reference, were elaborated and their physico-chemical composition was determined. Second, to determine the acceptability of consumer, apple fibre co products were added (6, 10 and 14%). Products were evaluated for their texture using a texturometer and sensory characteristics using an acceptance test. Results showed that physico-chemical composition of cereal bars elaborated with co-products was slightly different compared to those elaborated with commercial fibre. All bars have low water activity levels (~0.470) and interesting energy (300 kcal/100 g bar). External appearance revealed a darker colour (L*:~42/a*:~8/b*:~20). There were no significant differences (P > 0.05) in texture values (hardness: 40.8 N; cohesiveness: 0.34; springiness: 0.60; chewiness: 8.30 N) between cereal bars prepared with pear co-product and wheat bran. Acceptance test confirms the formulation used for cereals bars and showed that incorporation of 10% of co-product produced cereal bars with the highest acceptability. Sensory characteristics revealed that appearance is the limiting factor for consumer acceptability, essentially for cereal bars containing pear co product. Apple, pear and date co-products could be used successfully as a food ingredient to develop new formulations of cereal bars. PMID- 29169268 TI - Contamination sources, biofilm-forming ability and biocide resistance of Staphylococcus aureus in tilapia-processing facilities. AB - The major contamination sources, biofilm-forming ability and biocide resistance of Staphylococcus aureus in tilapia-processing plants were evaluated. Twenty-five processing control points were analysed twice in two factories, including whole tilapias, frozen fillets, water and food-contact surfaces. No final product was contaminated with S. aureus. However, high concentrations of S. aureus carrying enterotoxin ( se) genes were found in several processing points of both factories due to the application of inadequate hygienic and handling procedures, which generate a high risk of cross-contamination of the tilapia fillets with staphylococcal enterotoxins. Nine S. aureus strains were characterized by RAPD PCR using primers AP-7, ERIC-2 and S. A wide diversity of se gene profiles was detected, most strains being multi- se-carriers. All S. aureus strains showed high biofilm-forming ability on stainless steel and polystyrene. Biofilm-forming ability was correlated with the presence of fliC H7 and the type of origin surface (metallic or plastic). A marked resistance of S. aureus to peracetic acid and sodium hypochlorite was also observed, required doses being higher than those recommended by manufacturers to be eradicated. Case-by-case approaches are thus recommended to determine the sources and degree of contamination present in each factory, which would allow applying precise responses that avoid, or at least reduce, the presence of bacterial pathogens and the emergence of antimicrobial resistance.

AB - More than two thirds of adults and one third of children are overweight or obese in the United States. These trends have led to initiatives to provide information that supports informed choices. Traffic light labeling has been shown to increase consumer awareness and encourage healthy selections. This article contributes to the literature on healthy choices by comparing the additional contribution of a number of interventions used in combination with traffic light labeling. We conducted a 21-month field study in a workplace cafeteria. We analyzed cash register receipts, focusing on sales of beverages and chips. We found that the traffic light system was effective. The addition of caloric information to traffic light labeling had a positive effect on the purchase of healthy chips. However, other interventions appeared to produce more harm than good, essentially wiping out the benefits from traffic light labeling. These findings suggest that although it is possible to improve on traffic light labeling with selective interventions, caution is in order as some interventions may trigger compensatory behavior that results in the purchase of unhealthy items. PMID- 29169271 TI - Differentiation of mesenchymal stem cells into neuron-like cells using composite 3D scaffold combined with valproic acid induction. AB - The nervous system has little capacity for self-repair after injury because neurons cannot proliferate owing to lack of suitable microenvironment. Therefore, neural tissue engineering that combines neural stem, scaffolds, and growth factors may improve the chance of restoration of damaged neural tissues. A favorable niche for neural regeneration would be both fibrous and electrically conductive scaffolds. Human Wharton jelly-derived mesenchymal stem cells were seeded on wet-electrospun 3D scaffolds composed of poly lactic acid coated with natural polymers including alginate and gelatin, followed by a multi-wall carbon nanotube coating. The results show that a wet-electrospun poly lactic acid scaffold at a concentration of 15% w/v had higher porosity (above 80%) than other concentrations. Moreover, the coated scaffold supported the growth of human Wharton jelly-derived mesenchymal stem cells in 3D culture, and were incubated for 21 days with 1 mM valproic acid as the inducer resulted in improvement in human Wharton jelly-derived mesenchymal stem cells differentiation into neuron like cells immunoreactivity to nestin, Map2, and neuron specific enolase (NSE), which were also consistent with reverse transcription polymerase chain reaction (RT-PCR) and quantitive Reverse transcription polymerase chain reaction (qRT-PCR) results. The conclusion is that the 3D composite nanofiber poly lactic acid scaffold improved the transdifferentiation of human Wharton jelly-derived mesenchymal stem cells into neuron-like cells.

AB - Phyllodes tumor is a relatively uncommon fibroepithelial neoplasm of the breast characterized by proliferation of both stromal and epithelial elements. Benign phyllodes tumors are distinguished from fibroadenomas by their prominent leaf like architecture and exaggerated intracanalicular stromal growth pattern. Typically, these lesions affect older natal females; however, we present what we believe is the first reported case of benign phyllodes tumor in a hormonally treated transgender woman. PMID- 29169273 TI - Evaluating the Implementation of a Farmers' Market Targeting WIC FMNP Participants. AB - The present study planned and implemented a new farmers' market (FM) at a WIC (Special Supplemental Nutrition Program for Women, Infants, and Children) clinic in North Carolina, of which WIC FM Nutrition Program (FMNP) participants were the main priority population. The purpose of this FM was to provide convenience and improve access to locally grown fresh fruits and vegetables in the community and to increase the FMNP coupon redemption rate. The main objective of this study was to describe the overall process and key strategies involved in implementing a FM at a WIC clinic. A community-based participatory research design using different formative methods documented the process and key inputs in FM implementation. Local farmers, program administrators, and community advocates were involved in documenting the implementation process. Multiple formative methods included direct observation and semistructured interviews with staff and farmers (n = 13). A community partnership was key in implementing the FM. The market operated weekly over the course of 24 weeks, involved 12 WIC-approved farmers, and featured over 50 types of fresh fruits and vegetables. The FMNP coupon redemption rate at the county level increased from 51.3% to 62.9%. The results demonstrate that a FM can be successfully located near a WIC clinic with positive effects of increasing availability to fresh fruits and vegetables for a low-income population and revenue for local farmers.

PMID- 29169275 TI - Functionalised nanomaterials for eradication of CSCs, a promising approach for overcoming tumour heterogeneity. AB - Today, intratumoural heterogeneity has been recognised as one of the main causes of cancer treatment failure and drug resistance development through which multiple mechanisms are simultaneously involved. From the broad diversity of cells presented in tumour microenvironment, owing to their proliferative potential and longevity, cancer stem cells (CSCs), are the main cell subpopulation involved in tumour development, propagation, metastatic dissemination and induction of intratumoural heterogeneity. Accordingly, selective targeting and eradication of CSCs may represent a promising approach for cancer therapy and evading drug resistance development. Nanotechnology is an attractive outgrowing field in medicine due to its promising capabilities in solving several obstacles associated with conventional chemotherapy agents including poor solubility, lack of selectivity and high systemic toxicity. Accordingly, multiple types of nanocarriers have been successfully developed for improving selective delivery and reducing non-selective toxicities of CSC specific chemotherapy agents. In Current review, we mostly focus on examining the role of CSCs in development of intratumoral heterogeneity and introducing recently developed nano delivery systems for more efficient targeting and eradication of them. PMID- 29169276 TI - Iatrogenic Kaposi's Sarcoma in an HIV-Negative Young Male With Crohn's Disease and IgA Nephropathy: A Case Report and Brief Review of the Literature. AB - BACKGROUND: Kaposi's sarcoma (KS) is a vascular tumor arising in association with human herpesvirus-8 (HHV-8) infection, and different variants show different clinical presentations. Isolated intestinal KS in the background of Crohn's disease (CD) is exceedingly rare with only 3 cases reported in the English literature (from 1966 to 2016). CASE PRESENTATION: Herein, we report a case of intestinal KS in a 21-year-old HIV-negative Ethiopian male with a long-standing history of steroid therapy for his underlying IgA nephropathy. Recent gastrointestinal biopsies confirmed an additional diagnosis of CD. Despite the addition of Infliximab to his therapy, his CD remained refractory, and a laparoscopic-assisted ileocolectomy was performed to alleviate a partial small bowel obstruction. Examination of his terminal ileum demonstrated a polypoid mass with adjacent incidental ileal submucosal nodules. These nodules were composed of plump spindle cells with scattered mitoses and vascular channels with extravasated red blood cells. Intratumoral hyaline globules were also noted. Immunohistochemistry revealed HHV-8 positivity, confirming the histologic impression of KS. CONCLUSIONS: Here we report the fourth case of KS in CD in an HIV-negative patient and only the third case of isolated intestinal KS in the setting of CD. A review of the literature suggests that attenuation of immunosuppressive therapy may be adequate management of iatrogenic KS in the absence of a systemic HHV-8 infection. PMID- 29169277 TI - Reconstructing protein and gene phylogenies using reconciliation and soft clustering. AB - The architecture of eukaryotic coding genes allows the production of several different protein isoforms by genes. Current gene phylogeny reconstruction methods make use of a single protein product per gene, ignoring information on alternative protein isoforms. These methods often lead to inaccurate gene tree reconstructions that require to be corrected before phylogenetic analyses. Here, we propose a new approach for the reconstruction of gene trees and protein trees accounting for alternative protein isoforms. We extend the concept of reconciliation to protein trees, and we define a new reconciliation problem called MinDRGT that consists in finding a gene tree that minimizes a double reconciliation cost with a given protein tree and a given species tree. We define a second problem called MinDRPGT that consists in finding a protein supertree and a gene tree minimizing a double reconciliation cost, given a species tree and a set of protein subtrees. We propose a shift from the traditional view of protein ortholog groups as hard-clusters to soft-clusters and we study the MinDRPGT problem under this assumption. We provide algorithmic exact and heuristic solutions for versions of the problems, and we present the results of applications on protein and gene trees from the Ensembl database. The implementations of the methods are available at https://github.com/UdeS CoBIUS/Protein2GeneTree and https://github.com/UdeS-CoBIUS/SuperProteinTree .

PMID- 29169279 TI - Evaluation of Intravenous Vancomycin Pharmacokinetic Parameters in Patients With Acute Brain Injury. AB - BACKGROUND: Vancomycin is a glycopeptide antibiotic that is primarily cleared by renal elimination. Patients with acute brain injury often exhibit augmented renal clearance which has been associated with subtherapeutic vancomycin concentrations. OBJECTIVE: To determine whether population pharmacokinetics accurately predict vancomycin empiric dose frequency in patients with acute brain injury. METHODS: This was a single-center, retrospective cohort study conducted following institutional review board approval at Virginia Commonwealth University Health System. Data were collected from patients 18 years of age or older admitted with acute brain injury. The primary outcome was the difference in the elimination rate constant of vancomycin between population predicted pharmacokinetics and patient-specific pharmacokinetics. RESULTS: A total of 158 patients were included in the analysis. A test of the paired differences between the mean population predicted and patient-specific elimination rate constants showed that the mean population predicted elimination rate constant was larger by 0.0211 h-1 (95% confidence interval [CI]: -0.028 to -0.015). The difference between the mean population predicted and patient-specific half-lives showed that the mean population predicted half-life was shorter by 1.01 hours (95% CI: 0.7 1.3). Vancomycin was administered at a mean initial dose of 15.4 mg/kg (standard deviation [SD] = 2.2), with an average frequency of 12 hours (SD = 1.1). The average trough concentration at steady state was 9.9 ug/mL (SD = 4.9). CONCLUSIONS: The small clinical difference in population and patient-specific elimination rate constants demonstrates that population pharmacokinetics may be an accurate empiric dosing strategy for determining vancomycin dose frequency in patients with acute brain injury.

PMID- 29169281 TI - Pitfalls of Frozen Section Diagnosis for Paraganglioma: A Clinicopathologic Analysis and Review of the Literature. AB - Few paraganglioma (PG) cases include frozen section diagnoses, and therefore, the accuracy of frozen section diagnosis for PG remains unknown. To better understand the histologic characteristics and pitfalls of frozen section findings for PG, 15 PG cases with frozen section diagnoses were selected from 12 articles through PubMed (1984-2015). In addition, we included 3 cases of PG for which intraoperative consultations were requested during a 5-year period (2012-2016) in 2 hospitals. Seven PGs were from the thyroid; 2 from the pancreas; 4 from the mediastinum, retroperitoneum, or mesentery; 1 from the middle ear; and 4 from the urinary bladder (UB). Out of 18 PGs, correct diagnoses were rendered in only 2 cases, and no thyroid or UB PGs were correctly diagnosed on intraoperative consultation. Thyroid PGs were frequently misdiagnosed as medullary thyroid carcinomas (4/7, 57%) and UB PGs were frequently misdiagnosed as malignancies.

Despite a decline in breast cancer mortality, prognosis of advanced breast cancer remains poor. In a desperate need to improve breast cancer outcomes, newer agents that target molecular pathways are being tested. Deregulation of the phosphoinositide 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) is frequently found in breast cancer. This can lead to resistance of endocrine therapy and anti-HER2 therapies. Targeting this pathway may restore sensitivity to these compounds. Buparlisib (BKM-120) is an orally active pan-PI3K inhibitor evaluated in different tumor types. Areas covered: Buparlisib is one of the most investigated PI3K inhibitors. Preclinical and clinical studies of buparlisib in breast cancer are analyzed and discussed. This article reviews the status of buparlisib, completed and ongoing trials, and its safety. Expert opinion: PI3K inhibitors show promising results in breast cancer. However, we raise a number of issues including the identification of biomarkers to predict treatment response and strategies to counteract resistance. Moreover, its toxicity profile could limit its extensive use. PMID- 29169283 TI - Time-lapse microscopic observation of non-dividing cells in cultured human osteosarcoma MG-63 cell line. AB - Cancer stem cells resemble normal tissue-specific stem cells in many aspects, such as self-renewal and plasticity. Like their non-malignant counterparts, cancer stem cells are suggested to exhibit a relative quiescence. The established cancer cell lines reportedly harbor slow-proliferating cells that are positive for some cancer stem cells markers. However, the fate of these cells and their progeny remains unknown. We used time-lapse microscopy and the contrast-based segmentation algorithm to identify and monitor actively dividing and non-dividing cells in human osteosarcoma MG-63 cell line. Within the monitored field of view the non-dividing cells were represented by three cells that never divided, and one cell that attempted to divide, but failed cytokinesis, and later, after significantly prolonged division, produced the progeny with enlarged segmented nuclei, thus pointing to a possible mitotic catastrophe. Together, these cells initially constituted about 6.2% of the total number of seeded cells, yet only 0.02% of all cells at the end of the observation period when cells became confluent. Non-dividing cells were characterized by rounded shape, dark nuclei, random cytoplasmic streaming and subtle oscillatory movement, however, they did not migrate and rarely formed cell-cell contacts as compared to actively dividing cells. Our data indicate that the observed non-dividing MG-63 cells do not have a growth advantage over other cells and, therefore, they do not contribute to the cancer stem cells pool.

(Zingiberaceae) with anti-aging, anticancer, anti-Alzheimer's disease, antioxidant and other medicinal properties. OBJECTIVE: The relaxant effect of C. longa on rat tracheal smooth muscle and its possible mechanisms were investigated in this study. MATERIALS AND METHODS: The relaxant effects of four cumulative concentrations of hydro-ethanol extract of C. longa (6.25, 12.5, 25, 50 mg/mL) were studied on tracheal smooth muscle precontracted by methacholine or KCl in non-incubated or incubated with different substances including propranolol, diltiazem, L-NAME, glibenclamide, atropine, chlorpheniramine, indomethacin and papaverine. The duration of the study was 84 days. RESULTS: In non-incubated tracheal smooth muscle, the extract of C. longa showed significant concentration dependent relaxant effects (p < 0.001 for all concentrations on both KCl and methacholine-induced contraction). There was no significant difference in the relaxant effects between C. longa and theophylline in both methacholine and KCl induced contraction conditions. In tissues incubated with propranolol, diltiazem, L-NAME and glibenclamide on methacholine-induced contraction and in tissues incubated with atropine, chlorpheniramine, indomethacin and papaverine on KCl induced contraction, the extract also showed significant concentration-dependent relaxant effects (p < 0.001). EC50 values of C. longa between non-incubated (16.22 +/- 0.62) and incubated tissues (atropine: 13.03 +/- 0.55, chlorpheniramine: 12.94 +/- 0.68, indomethacin: 14.80 +/- 0.57 and papaverine: 16.16 +/- 1.42) were not significantly different. CONCLUSIONS: Tracheal smooth muscle relaxant effects of C. longa, were comparable to those of theophylline, which could be due to the presence of methylxanthines or its possible interaction with non-adrenergic non-cholinergic nervous system. PMID- 29169286 TI - Sclerosing Mucoepidermoid Carcinoma in the Parotid Gland With CRTC1-MAML2 Fusion: A Case Report. AB - In this article, we report a case of sclerosing mucoepidermoid carcinoma (MEC) arising in the parotid gland, with CRTC1-MAML2 gene fusion. A 73-year-old woman with a mass in the right parotid region was referred to our hospital. Radiological imaging tests revealed a well-defined mass, measuring 25 mm in diameter, with foci of calcification in the deep lobe of the parotid gland, extending to the parapharyngeal space. Microscopically, the tumor was composed of a proliferation of atypical glandular epithelial cells having intracytoplasmic mucin, squamoid cells, and intermediate cells arranged in nests embedded in a fibrosclerotic stroma, associated with a dense chronic inflammatory infiltrate containing immunoglobulin G4-immunoreactive plasma cells. Reverse transcription polymerase chain reaction analysis using a formalin-fixed, paraffin-embedded tumor tissue specimen revealed the CRTC1-MAML2 fusion gene transcript. This is the first report of sclerosing MEC with the detection of the MEC-associated fusion gene, reinforcing a common genetic association between MEC and sclerosing MEC. PMID- 29169284 TI - VEGFC/VEGFR3 Signaling Regulates Mouse Spermatogonial Cell Proliferation via the Activation of AKT/MAPK and Cyclin D1 Pathway and Mediates the Apoptosis by affecting Caspase 3/9 and Bcl-2. AB - We have previously shown that the transcript levels of Vegfc and its receptor Vegfr3 were high in spermatogonia and extremely low in spermatocytes and spermatids. However, it remains unknown about the functions and the mechanisms of VEGFC/VEGFR3 signaling in regulating the fate determinations of spermatogonia. To this end, here we explored the role and signaling pathways of VEGFC/VEGFR3 by using a cell line derived from immortalized mouse spermatogonia retaining markers of mitotic germ cells, namely GC-1 cells. VEGFR3 was expressed in mouse primary spermatogonia and GC-1 cells. VEGFC stimulated the proliferation and DNA synthesis of GC-1 cells and enhanced the phosphorylation of PI3K-AKT and MAPK, whereas LY294002 (an inhibitor for AKT) and CI-1040 (an inhibitor for MAPK) blocked the effect of VEGFC on GC-1 cell proliferation. Furthermore, VEGFC increased the transcripts of c-fos and Egr1 and protein levels of cyclin D1, PCNA and Bcl-2. Conversely, the blocking of VEGFC/VEGFR3 signaling by VEGFR3 knockdown reduced the phosphorylation of AKT/MAPK and decreased the levels of cyclin D1 and PCNA. Additionally, VEGFR3 knockdown not only resulted in more apoptosis of GC-1 cells but also led to a decrease of Bcl-2 and promoted the cleavage of Caspase 3/9 and PARP. Collectively, these data suggested that VEGFC/VEGFR3 signaling promotes the proliferation of GC-1 cells via the AKT /MAPK and cyclin D1 pathway and it inhibits the cell apoptosis through Caspase-3/9, PARP and Bcl-2. Thus, this study sheds a novel insight to the molecular mechanisms underlying the fate decisions of mammalian spermatogonia. PMID- 29169287 TI - Point-of-care testing (POCT) and evidence-based laboratory medicine (EBLM) - does it leverage any advantage in clinical decision making? AB - Point-of-care testing (POCT) is the analysis of patient specimens outside the clinical laboratory, near or at the site of patient care, usually performed by clinical staff without laboratory training, although it also encompasses patient self-monitoring. It is able to provide a rapid result near the patient and which can be acted upon immediately. The key driver is the concept that clinical decision making may be delayed when samples are sent to the clinical laboratory. Balanced against this are considerations of increased costs for purchase and maintenance of equipment, staff training, connectivity to the laboratory information system (LIS), quality control (QC) and external quality assurance (EQA) procedures, all required for accreditation under ISO 22870. The justification for POCT depends upon being able to demonstrate that a more timely result (shorter turnaround times (TATs)) is able to leverage a clinically important advantage in decision making compared with the central laboratory (CL). In the four decades since POCT was adapted for the self-monitoring of blood glucose levels by subjects with diabetes, numerous new POCT methodologies have become available, enabling the clinician to receive results and initiate treatment more rapidly. However, these instruments are often operated by staff not trained in laboratory medicine and hence are prone to errors in the analytical phase (as opposed to laboratory testing where the analytical phase has the least errors). In some environments, particularly remote rural settings, the CL may be at a considerable distance and timely availability of cardiac troponins and other analytes can triage referrals to the main centers, thus avoiding expensive unnecessary patient transportation costs. However, in the Emergency Department, availability of more rapid results with POCT does not always translate into shorter stays due to other barriers to implementation of care. In this review, we apply the principles of evidence-based laboratory medicine (EBLM) looking for high quality systematic reviews and meta-analyses, ideally underpinned by randomized controlled trials (RCTs), looking for evidence of whether POCT confers any advantage in clinical decision making in different scenarios. PMID- 29169288 TI - Human studies with microneedles for evaluation of their efficacy and safety. AB - INTRODUCTION: During the past two decades, many studies have documented the development of microneedles (MNs) as a feasible technique for the effective administration of drugs. More and more human studies have been done with MNs to bridge the gap between research and market applications that provide efficacious techniques for clinical implementation. Areas covered: The aim of this review is provide a brief description of the status of human study with MNs and to demonstrate progress for the right use of microneedle arrays in clinical settings. It also describes the considerations for clinical application with each type of MNs. Expert opinion: Microneedle systems were introduced to overcome the limitations of conventional methods of drug administration. Lots of microneedle systems have undergone clinical evaluation to determine their efficacy and safety, and many studies have demonstrated positive results. The successful clinical use of the microneedle in vaccine therapy is remarkable and supports the importance of conducting further tests in a wide range of medical applications. Self-administered MNs appeared to be an attractive alternative method that needs further research to become a reality in the near future.

AB - The aim was to describe school nurses' experiences working with students with mental health problems. In this inductive qualitative study, interviews were conducted with 14 school nurses in Sweden. The content analysis revealed three themes: (1) sense of worriedness about working with students with mental health problems, (2) taking care of students with mental health issues was an opportunity for personal and professional development, and (3) the experience of making a difference for young people with mental health problems. The school nurses working with students who have mental health problems had to cope with their own emotions, worries, and feelings of insufficiency. However, the school nurses also found the work to be meaningful and rewarding because they appreciated the opportunity for personal and professional development while taking care of students with mental health problems. They felt grateful for having a profession that had a huge impact on children's/adolescents' lives.

Using a pedagogical sociocultural perspective, the research focused on individuals' perspectives and understandings as well as their account of social interaction, working and learning. In all, 17 people working in daily activity services were interviewed once, and, of these, 14 were interviewed a second time. Using qualitative content analysis, two themes and three categories were singled out. The results show that participation can be understood in two major ways: social interaction and performing work tasks.

AB - The activity concentration of natural (238U, 232Th, and 40K) and artificial (137Cs) radionuclides was determined in 50 samples (obtained from the same station) from various species of mushrooms and soil collected from the Middle Black Sea Region (Turkey). The activities of 238U, 232Th, 40K, and 137Cs were found as 84 +/- 16, 45 +/- 14, 570 +/- 28, and 64 +/- 6 Bq kg-1 (dry weight), respectively, in the mushroom samples and as 51 +/- 6, 41 +/- 6, 201 +/- 11, and 44 +/- 4 Bq kg-1, respectively, in the soil samples for the entire area of study. The results of all radionuclide activity measurements, except those of 238U and 232Th in the mushroom samples, are consistent with previous studies. In the soil samples, the mean values of 238U and 232Th are above the world mean, and the activity mean of 40K is below the world mean. Finally, the activity estimation was made with both the soil and mushroom samples for unmeasured points within the study area by using the ordinary kriging method. Radiological distribution maps were generated. PMID- 29169292 TI - Use of a translucent refuge for Xenopus tropicalis with the aim of improving welfare. AB - Xenopus tropicalis is an increasingly important animal model in a variety of biological research fields. In many countries legislation exists to promote and increase welfare wherever possible, including the ability to view animals during daily husbandry with minimal stress to the animal. X. tropicalis ( n = 16) refuge use was investigated; it was found that the animals significantly preferred black opaque overhead cover to open-ended pipes or closed-off ceramic plants pots in refuge choice experiments. This experiment was repeated by replacing the opaque black overhead cover with red filters. A significant preference for overhead cover was seen for the red translucent cover compared with other available refuges, suggesting that X. tropicalis may adopt translucent refuges due to their visual inabilities. The inability of frogs to see certain wavelengths of light may allow staff to view them whilst simultaneously providing the refuge of choice. PMID- 29169293 TI - Qualitative Analysis of Faith Community Nurse-Led Cognitive-Behavioral and Spiritual Counseling for Dementia Caregivers. AB - This article presents themes emerging from semistructured interviews with dementia family caregivers in rural communities who participated in an integrative, cognitive-behavioral and spiritual counseling intervention, and with faith community nurses (FCNs) who delivered the intervention. The primary objectives of the counseling intervention were to ameliorate dementia caregivers' depressive affect and the severity of their self-identified caregiving and self care problems. The qualitative portion of the study was intended to elicit caregivers' and FCNs' perceptions of the benefits and drawbacks of the intervention. We conducted interviews with seven FCN/caregiver pairs 4 times during the 6-month counseling process, totaling 56 interviews. Themes emerging from the interviews included caregivers' perception of burden and care partners' problem behavior; formation of therapeutic alliance between FCNs and caregivers; problem-solving skills, tools, and resources; caregivers' use of problem-solving strategies; spirituality in caregiving and counseling processes; FCNs' prior professional experience; and caregiver and FCN time constraints. PMID- 29169294 TI - Susceptibility of functional impairment scales to noncredible responses in the clinical evaluation of adult ADHD. AB - OBJECTIVE: A growing body of research questions the reliance of symptom self reports in the clinical evaluation of attention-deficit/hyperactivity disorder (ADHD) in adulthood. A recent study suggested that also impairment reports are vulnerable to noncredible responses, as derived from a simulation design using a global functional impairment scale. The present study aims to add evidence to this issue, by using an ADHD specific impairment scale in a simulation design on large samples. METHOD: Impairment ratings on the Weiss Functional Impairment Rating Scale (WFIRS) of 62 patients with ADHD were compared to 142 healthy individuals who were instructed to show normal behavior. Furthermore, impairment ratings of patients with ADHD were compared to ratings of 330 healthy individuals who were randomly assigned to one of four simulation conditions that were instructed to complete the scale as if they had ADHD. RESULTS: Patients with ADHD reported higher levels of impairment than the healthy control group in all domains of life. Furthermore, individuals instructed to feign ADHD indicated higher levels of impairments in most domains of life compared to control participants and genuine patients with ADHD. The group differences between individuals feigning ADHD and individuals with genuine ADHD, however, were only small to moderate. Further analyses revealed that the WFRIS was not useful to successfully differentiate genuine from feigned ADHD. CONCLUSIONS: The present study confirms the conclusion that self-reported impairments are susceptible to noncredible responses and should be used with caution in the clinical evaluation of adult ADHD.

Before the implementation of nationwide German skin cancer screening, the pilot project SCREEN was conducted in Schleswig-Holstein in 2003-2004. We aimed to determine whether the pilot project had achieved a mortality reduction. Methods Using an incidence-based approach (patients with both melanoma diagnosis and death in 2003-2008), we compared the observed melanoma mortality of the SCREEN cohort to the melanoma mortality expected without screening in the general population of Saarland. Results The age- and sex-standardized melanoma mortality ratio (SMR) for 5.5 years of follow-up was 0.59 (95% confidence interval, 0.40 0.83). Conclusion Our results indicate reduced mortality in the SCREEN cohort. Several potential biases cannot be excluded, but most of them tend to inflate the SMR. PMID- 29169296 TI - Blackfullas in ivory towers: referenced reflections of a Bundjalung graduate nurse. AB - BACKGROUND: Indigenous representation is essential to ensure the health workforce is culturally capable and safe for Indigenous patients. However, Indigenous Peoples remain underrepresented in tertiary education and the health workforce. AIM: This aim of this paper is to offer an unmediated, Aboriginal nurses' perspective, on the experience, barriers and challenges of undertaking a Bachelor of Nursing degree. DESIGN: Referenced reflection. RESULTS: Education providers must be culturally capable themselves before teaching Indigenous content and facilitating sensitive classroom discussions. Financial, social and educational support is crucial to equip Indigenous students for tertiary study. CONCLUSION: To retain Indigenous students and contribute to a culturally capable workforce, it is imperative to listen and respond to Indigenous Peoples voices to shape learning experiences and support.

AB - The age-related decline in working memory (WM) has been studied extensively. Yet, research has focused mainly on one aspect of memory, in which older adults memorised information provided to them, neglecting the frequent everyday behaviour in which memory is self-initiated (SI), meaning that individuals memorise information they selected themselves. The present study used a modified spatial span task in which young and older adults memorised spatial sequences they constructed themselves, or random sequences provided to them. The results revealed that young and older adults carefully planned and constructed structured spatial sequences, by minimising distances between successive locations, and by selecting sequences with fewer path crossings and with more linear shapes. Older adults constructed sequences that were even more structured in some aspects. Young and older adults benefited from self-initiation to the same extent, showing similar age-related declines in SI and provided spatial WM. Overall, the study shows that older adults have access to metacognitive knowledge on the structure of efficient WM representations that benefit accuracy, and shows that older adults can use strategic encoding processes efficiently when encoding is SI. More generally, SI WM explores an important aspect of behaviour, demonstrating how older adults shape their environment to facilitate cognitive functioning.

AB - Until discontinued in 2008, the Scottish Hip Fracture Audit collected and reported on data relating to the quality of care of hip fracture patients in Scotland. In 2013, the audit was recommenced under the umbrella of the MSK Audit group, which audits high volume orthopaedic pathways across Scotland. Our aim is to report on the changes in the demographics of hip fracture patients in Scotland between 2003 and 2013. There was an increase in the proportion of male patients from 2003 to 2013 (22.4% to 29.5%; p < 0.0001). An increased percentage of hip fracture patients were admitted from their own home (63.9% to 73.1%; p < 0.0001). Both these factors have deleterious effects on the outcome, and use of necessary resources, following hip fracture. There was also an increase in the percentage of patients who were American Society of Anesthesiologists Grade 3 (52.9% to 56.4%). Over the last decade, there has been a shift in the demographics of Scotland's hip fracture patients. If hip fracture incidence increases as predicted, this potentially more-challenging case-mix will likely impact on multiple health resources. PMID- 29169300 TI - Arterio-biliary fistulas: What to choose as endovascular treatment? AB - Objectives Endovascular procedures are the treatment of choice in cases of intrahepatic fistulas. Arterio-biliary fistulas are the rarest and most difficult to treat, due to high risk of infection. Methods Eight cases of persistent hemobilia that developed as a result of arterio-biliary fistulas are presented. Five cases developed as a result of iatrogenic injury, two cases as a result of chronic infection, one case as a consequence of trauma. Results Patients were treated using endovascular embolization or combined endovascular and endoscopic biliary tract revision. The results were monitored after six to seven days and one month after embolization. The embolizations were considered effective in all cases. One patient had four asynchronous fistulas requiring separate treatments sessions. Four patients required a revision of their biliary ducts after embolization and restoration of patency. In one patient, a migration of the coil to biliary ducts occurred. Conclusion Endovascular treatment of arterio-biliary fistulas is safe and effective. The use of embolization with soft and biodegradable materials like histoacrylic glue or thrombin may be the optimal method of treatment in comparison with coils which have a risk of migration or chronic infection. PMID- 29169301 TI - Utilization of stent grafts in the management of arteriovenous access pseudoaneurysms. AB - Objective Endovascular stent graft repair for exclusion of pseudoaneurysm is currently being explored to replace open surgical repair as current management. The objective of the study was to evaluate the clinical safety and efficacy of endovascular stent graft intervention in pseudoaneurysms complicating arteriovenous reconstructions in patients on chronic hemodialysis. Methods A retrospective analysis of all pseudoaneurysms treated with stent grafts at our institution over a period of five years was performed. The indications for endovascular intervention included bleeding from the pseudoaneurysm, infection, and significant skin compromise overlying the pseudoaneurysm or combination of the above. The rates of technical success, complication, and primary patency were measured at one-week, one-month, and six-month follow-up. Results A total of 33 endovascular stent graft interventions in 29 patients were performed for the treatment of pseudoaneurysms. The average age of patients was 68 years (range 31 90 years), with 13 female. Diabetes and hypertension were present in 15 and 22 patients, respectively. In eight patients, there was evidence of active infection at the fistula site. The choice of stent grafts include Viabahn ( n = 31), Wallgraft ( n = 1), and i-Cast ( n = 1). The initial technical success rate was 94%. The two failed interventions included occlusion of inflow artery with immediate conversion to open procedure ( n = 1) and incomplete pseudoaneurysm exclusion ( n = 1). Primary patency at one month and six months was 83 and 60%, respectively. An additional balloon angioplasty of outflow tract or central stenosis was performed in 18 cases (54%). The explanation of stent grafts due to persistent or recurrent bacteremia/site infection was required in four out of eight patients. The average time to explanation was 93 days (range 6-204 days). Conclusion The stent graft implantation is a safe, minimally invasive and efficient way to control and manage arteriovenous accesses with pseudoaneurysms. In the presence of infection, this approach may be less durable. PMID- 29169303 TI - Inclusion and exclusion strategies for conducting meta-analyses. AB - Some of the most important decisions that a researcher will make when conducting a meta-analysis are decisions about the search strategies and inclusion/exclusion criteria. Decisions regarding inclusion/exclusion criteria serve to define the scope of a meta-analysis and search strategy decisions can have a large impact on how well the results of a meta-analysis actually represent the existing body of literature. In this article, we provide descriptions and recommendations for performing searches and making inclusion/exclusion decisions. We also provide a review of 65 meta-analyses of psychotherapy versus pharmacotherapy in order to offer frequency data on the use of various search strategies and inclusion/exclusion decisions in the field. PMID- 29169302 TI - Laughter therapy as an intervention to promote psychological well-being of volunteer community care workers working with HIV-affected families. AB - The study explores the experiences of volunteer community care workers working with HIV-affected families, participating in laughter therapy. Laughter therapy is being used as an intervention to positively influence individuals experiencing various forms of emotional distress. Community care workers play a vital role in the support of the HIV/AIDS-infected and -affected members in communities. The nature of this type of work and their limited training contributes to high levels of secondary trauma and emotional exhaustion. The purpose of the study was firstly, to explore the effects of working with orphans and vulnerable children (OVC) on the community care workers and secondly, to establish the impact that laughter therapy has to positively combat stresses of working within the care workers' environment. All the community care workers from a community-based organisation that provides care for HIV/AIDS-infected and -affected OVC and their families in the greater region of Soweto, South Africa, took part in daily laughter therapy sessions for one month. To assess the experiences of participants of laughter therapy, seven community care workers agreed to participate in a mixed method assessment. Interviews were conducted before and after the intervention using the Interpretative Phenomenological Analysis as framework. As supportive data, a stress and anxiety and depression scale were added in the interview. Participants reported more positive emotions, positive coping, improved interpersonal relationships and improvement in their care work after exposure to laughter therapy. Quantitative results on stress, anxiety and depression for each participant confirmed observed changes. Laughter therapy as a self-care technique has potential as a low-cost intervention strategy to reduce stress and counteract negative emotions among people working in highly emotional environments. PMID- 29169304 TI - Determination of the predictive clinical parameters to diagnose chronic exertional compartment syndrome. AB - Chronic exertional compartment syndrome (CECS) is characterized by pain occurring during physical activity. As clinical examination is not sufficient to diagnose it, intracompartmental pressure (ICP) measure is used for CECS confirmation. Numerous clinical signs are reported but their diagnosis predictive ability has never been studied. We aimed to determine if the 12 classically reported clinical signs are predictive of CECS. We performed a single-centre retrospective cohort study on patients referred for CECS suspicion. Patients were asked to run on a treadmill. When pain occurred, post-exercise ICP was performed. We diagnosed CECS if the ICP was >=30 mmHg and used a logistic regression to calculate the predictive value of clinical signs. One hundred twenty-five patients were evaluated. Ninety-six had CECS and 29 did not, according to the ICP 30 mmHg cut off. Anterior and lateral compartments were the most frequently affected. After exercise, mean ICP was 58.6 mmHg +/- 20.5 in the group with CECS versus 20.9 mmHg +/- 4 in the group without (p < .001). Muscle hardness, muscle hernia after exercise, absence of pain at rest and pain recidivism for the same exercise were predictive of CECS. The predictive model associated muscle hardness (Odds Ratio (OR) = 2.18; p < .001) and muscle hernia after exercise (OR = 1.44; p < .001). This model identified 88.6% of CECS subjects. The ROC curve area was 0.808 [95% CI: 0.71-0.90]. This study confirmed the importance of clinical parameters to diagnose CECS. A better knowledge of the relevant parameters could help physicians to indicate invasive examinations. PMID- 29169305 TI - The Vulnerability of Occupational Health and Safety to Deregulation: The Weakening of Information Regulations during the Economic Crisis in Korea. AB - This study was conducted to investigate the causes and consequences of the vulnerability of occupational health and safety (OHS) regulations to deregulation during a period of economic crisis in the Republic of Korea. Analysis of Korea's national regulation database revealed that the vulnerability of OHS regulations to deregulation was related to the fact that OHS policy included many regulations without direct deregulatory impacts on workers. The most affected victim of this characteristic was information regulation that provided a legal basis for government's monitoring and inspection of OHS activities. The massive relaxation of information regulation has the potential to weaken government oversight and to tempt businesses to hide industrial accidents. Since changes in regulations without direct deregulatory impacts are not easily identifiable by workers, careful monitoring of deregulation is necessary to prevent policy impacts harmful to workers' health and safety. PMID- 29169306 TI - Occupational Stress Among Home Healthcare Workers: Integrating Worker and Agency Level Factors. AB - Home healthcare work is physically and emotionally exhausting. In addition, home healthcare workers frequently work under precarious work arrangements for low wages and in poor work conditions. Little is known about how sources of job strain for home healthcare workers might be reduced. This research examines the occupational stressors among paid home care workers by analyzing home healthcare agency characteristics and individual home healthcare workers' experiences in upstate New York agencies (n = 9). The study augments existing theoretical models and describes new sources of stress arising from the nature of agency-based caregiving. Results feature the analysis of both agency executives' (n = 20) and home healthcare workers' narratives (n = 25) to make the agency's inner workings more transparent. Agency structures and culture are implicated in the lack of progress to address home care workers' health problems. Policy change should focus on compensation, healthier work conditions, and training requirements. PMID- 29169307 TI - Adult orthodontics in the Republic of Ireland: specialist orthodontists' opinions. AB - OBJECTIVES: To report the opinions of specialist orthodontists regarding the profile, characteristics and treatment of adults currently undergoing orthodontic treatment in the Republic of Ireland (ROI) Design/setting: A national cross sectional questionnaire study in the ROI. METHOD: A pilot-tested questionnaire was distributed to 122 specialist orthodontists in the ROI. Questions addressed general and treatment information for current adult orthodontic patients. Those whose treatment involved orthognathic surgery were not excluded. RESULTS: A response of 83% was obtained. Ninety-five per cent of specialists reported treating adults, most of whom were self-referred and were typically professional, female and aged 25-35 years. The overall ratio quoted of professionals to non professionals was almost 3:2. For 50% of specialists, males were estimated to account for 20-40% of their adult cases and for 23%, this increased to an estimated 40-60%. Class II division 1 malocclusion and skeletal II were considered the most common dentofacial characteristics. Occlusal features encountered in decreasing frequency were generalised crowding, increased overjet, deep overbite, late lower incisor crowding, spacing and impacted teeth. Fifteen per cent reported that at least 10% of their adult cases required orthodontics with maxillofacial surgery but 8% reported that this was at least 50%. Treatment challenges commonly acknowledged were overbite reduction, anchorage management, 'black triangles' and overjet reduction. Tooth whitening was reckoned to be used by 19% of specialists. Aesthetic upper and stainless steel lower brackets were indicated to be used most often whereas only 19% used clear aligners and 10% used lingual appliances often. CONCLUSIONS: The profile and characteristics of adults currently undergoing orthodontic treatment in the ROI were diverse. Higher estimates were quoted for self- than for general dental practitioner-referral. A high percentage of treatment was reported to be undertaken for non-professionals and males. A wide range of treatment and varying use of appliance types were cited. PMID- 29169308 TI - Factors influencing nurse-to-parent communication in culturally sensitive pediatric care: a qualitative study. AB - BACKGROUND: To deliver quality healthcare to diverse patients, effective commmunication is key. Little evidence exists about what factors influence nurse to-parent communication in culturally sensitive pediatric care. OBJECTIVE: The aim of this study was to explore factors that influence nurse-to-parent communication in the provision of culturally sensitive pediatric care. DESIGN: This study employed a qualitative content analysis. METHOD: The participants included 25 nurses and 9 parents from pediatric wards of hospitals located in Northwest and Central Iran. Semi-structured interviews were conducted. Data were analyzed using Graneheim and Lundman's method of content analysis. RESULTS: Factors that influenced the nurse-to-parent communication in pediatric culturally sensitive care were 1-organizational factors (inefficient policies and professional factors) and 2-human factors (nurse-related factors and unique characteristics of the family). Sub-categories included: lack of definitive policies for delivering cultural healthcare, insufficient cultural healthcare education, professional status of nursing in society, time, individual characteristics, cultural knowledge, cultural differences, and family's health literacy. CONCLUSION: The Iranian healthcare system requires a paradigm shift regarding the provision of culturally sensitive care.

PMID- 29169312 TI - Molecular Imaging of IGF-1R in Cancer. AB - The important role of insulin-like growth factor 1 receptor (IGF-1R) in malignant tumors has been well established. Increased IGF-1R activity promotes cancer cell proliferation, migration, and invasion and is associated with tumor metastasis, treatment resistance, poor prognosis, and shortened survival in patients with cancer. However, while IGF-1R has become a promising target for cancer therapy, IGF-1R-targeted therapy is ineffective in unselected patients. It is therefore essential to evaluate IGF-1R expression before treatment in order to identify responsive patients, monitor therapy efficacy, and estimate prognosis. Insulin like growth factor 1 receptor molecular imaging is an optimal method for assessing the expression of IGF-1R in vivo accurately and noninvasively. In this review, we will summarize the current status of IGF-1R molecular imaging in cancer, in which 5 major classes of ligands that have been developed for noninvasive IGF-1R molecular imaging will be discussed: natural ligands, monoclonal antibodies, antibody fragments, affibodies, and small molecules. For decades, IGF-1R molecular imaging is studied in full swing and more effort is needed in the future. PMID- 29169313 TI - Effect of Time-of-Flight and Regularized Reconstructions on Quantitative Measurements and Qualitative Assessments in Newly Diagnosed Prostate Cancer With 18F-Fluorocholine Dual Time Point PET/MRI. AB - Recent technical advances in positron emission tomography/magnetic resonance imaging (PET/MRI) technology allow much improved time-of-flight (TOF) and regularized iterative PET reconstruction regularized iterative reconstruction (RIR) algorithms. We evaluated the effect of TOF and RIR on standardized uptake values (maximum and peak SUV [SUVmax and SUVpeak]) and their metabolic tumor volume dependencies and visual image quality for 18F-fluorocholine PET/MRI in patients with newly diagnosed prostate cancer. Fourteen patients were administered with 3 MBq/kg of 18F-fluorocholine and scanned dynamically for 30 minutes. Positron emission tomography images were divided to early and late time points (1-6 minutes summed and 7-30 minutes summed). The values of the different SUVs were documented for dominant PET-avid lesions, and metabolic tumor volume was estimated using a 50% isocontour and SUV threshold of 2.5. Image quality was assessed via visual acuity scoring (VAS). We found that incorporation of TOF or RIR increased lesion SUVs. The lesion to background ratio was not improved by TOF reconstruction, while RIR improved the lesion to background ratio significantly ( P < .05). The values of the different VAS were all significantly higher ( P < .05) for RIR images over TOF, RIR over non-TOF, and TOF over non-TOF. In conclusion, our data indicate that TOF or RIR should be incorporated into current protocols when available. PMID- 29169314 TI - Word Recognition and Learning: Effects of Hearing Loss and Amplification Feature. AB - Two amplification features were examined using auditory tasks that varied in stimulus familiarity. It was expected that the benefits of certain amplification features would increase as the familiarity with the stimuli decreased. A total of 20 children and 15 adults with normal hearing as well as 21 children and 17 adults with mild to severe hearing loss participated. Three models of ear-level devices were selected based on the quality of the high-frequency amplification or the digital noise reduction (DNR) they provided. The devices were fitted to each participant and used during testing only. Participants completed three tasks: (a) word recognition, (b) repetition and lexical decision of real and nonsense words, and (c) novel word learning. Performance improved significantly with amplification for both the children and the adults with hearing loss. Performance improved further with wideband amplification for the children more than for the adults. In steady-state noise and multitalker babble, performance decreased for both groups with little to no benefit from amplification or from the use of DNR. When compared with the listeners with normal hearing, significantly poorer performance was observed for both the children and adults with hearing loss on all tasks with few exceptions. Finally, analysis of across-task performance confirmed the hypothesis that benefit increased as the familiarity of the stimuli decreased for wideband amplification but not for DNR. However, users who prefer DNR for listening comfort are not likely to jeopardize their ability to detect and learn new information when using this feature. PMID- 29169315 TI - Effectiveness of Two-Talker Maskers That Differ in Talker Congruity and Perceptual Similarity to the Target Speech. AB - Previous work has shown that masked-sentence recognition is particularly poor when the masker is composed of two competing talkers, a finding that is attributed to informational masking. Informational masking tends to be largest when the target and masker talkers are perceptually similar. Reductions in masking have been observed for a wide range of target and masker differences, including language: Performance is better when the target and masker talkers speak in different languages, compared with the same language. The present study evaluated normal-hearing adults' sentence recognition in a two-talker masker as a function of the perceptual similarity between the target and each of the two masker streams. The target was English, and the maskers were composed of English, time-reversed English, or Dutch. These three masker types are known to vary in the informational masking they exert. The two talkers within the two-talker maskers were either congruent (e.g., both English) or incongruent (e.g., one English, one Dutch). As predicted, mean performance was worse for the congruent English masker than the congruent time-reversed English or congruent Dutch maskers. Incongruent two-talker maskers, with just one English masker stream, were only modestly less effective than the congruent English masker. This result indicates that two-talker masker effectiveness was determined predominantly by the one masker stream that was most perceptually similar to the target. Speech recognition in a single-talker masker differed only marginally between the English, Dutch, and time-reversed English masker types, suggesting that perceptual similarity may be more critical in a two-talker than a one-talker masker. PMID- 29169316 TI - Coevolution of Siglec-11 and Siglec-16 via gene conversion in primates. AB - BACKGROUND: Siglecs-11 and -16 are members of the sialic acid recognizing Ig-like lectin family, and expressed in same cells. Siglec-11 functions as an inhibitory receptor, whereas Siglec-16 exhibits activating properties. In humans, SIGLEC11 and SIGLEC16 gene sequences are extremely similar in the region encoding the extracellular domain due to gene conversions. Human SIGLEC11 was converted by the nonfunctional SIGLEC16P allele, and the converted SIGLEC11 allele became fixed in humans, possibly because it provides novel neuroprotective functions in brain microglia. However, the detailed evolutionary history of SIGLEC11 and SIGLEC16 in other primates remains unclear. RESULTS: We analyzed SIGLEC11 and SIGLEC16 gene sequences of multiple primate species, and examined glycan binding profiles of these Siglecs. The phylogenetic tree demonstrated that gene conversions between SIGLEC11 and SIGLEC16 occurred in the region including the exon encoding the sialic acid binding domain in every primate examined. Functional assays showed that glycan binding preference is similar between Siglec-11 and Siglec-16 in all analyzed hominid species. Taken together with the fact that Siglec-11 and Siglec 16 are expressed in the same cells, Siglec-11 and Siglec-16 are regarded as paired receptors that have maintained similar ligand binding preferences via gene conversions. Relaxed functional constraints were detected on the SIGLEC11 and SIGLEC16 exons that underwent gene conversions, possibly contributing to the evolutionary acceptance of repeated gene conversions. The frequency of nonfunctional SIGLEC16P alleles is much higher than that of SIGLEC16 alleles in every human population. CONCLUSIONS: Our findings indicate that Siglec-11 and Siglec-16 have been maintained as paired receptors by repeated gene conversions under relaxed functional constraints in the primate lineage. The high prevalence of the nonfunctional SIGLEC16P allele and the fixation of the converted SIGLEC11 imply that the loss of Siglec-16 and the gain of Siglec-11 in microglia might have been favored during the evolution of human lineage. PMID- 29169317 TI - HashClone: a new tool to quantify the minimal residual disease in B-cell lymphoma from deep sequencing data. AB - BACKGROUND: Mantle Cell Lymphoma (MCL) is a B cell aggressive neoplasia accounting for about the 6% of all lymphomas. The most common molecular marker of clonality in MCL, as in other B lymphoproliferative disorders, is the ImmunoGlobulin Heavy chain (IGH) rearrangement, occurring in B-lymphocytes. The patient-specific IGH rearrangement is extensively used to monitor the Minimal Residual Disease (MRD) after treatment through the standardized Allele-Specific Oligonucleotides Quantitative Polymerase Chain Reaction based technique. Recently, several studies have suggested that the IGH monitoring through deep sequencing techniques can produce not only comparable results to Polymerase Chain Reaction-based methods, but also might overcome the classical technique in terms of feasibility and sensitivity. However, no standard bioinformatics tool is available at the moment for data analysis in this context. RESULTS: In this paper we present HashClone, an easy-to-use and reliable bioinformatics tool that provides B-cells clonality assessment and MRD monitoring over time analyzing data from Next-Generation Sequencing (NGS) technique. The HashClone strategy-based is composed of three steps: the first and second steps implement an alignment-free prediction method that identifies a set of putative clones belonging to the repertoire of the patient under study. In the third step the IGH variable region, diversity region, and joining region identification is obtained by the alignment of rearrangements with respect to the international ImMunoGenetics information system database. Moreover, a provided graphical user interface for HashClone execution and clonality visualization over time facilitate the tool use and the results interpretation. The HashClone performance was tested on the NGS data derived from MCL patients to assess the major B-cell clone in the diagnostic samples and to monitor the MRD in the real and artificial follow up samples. CONCLUSIONS: Our experiments show that in all the experimental settings, HashClone was able to correctly detect the major B-cell clones and to precisely follow them in several samples showing better accuracy than the state-of-art tool. PMID- 29169318 TI - Genome-wide DNA methylation profiling reveals novel epigenetic signatures in squamous cell lung cancer. AB - BACKGROUND: Epigenetic alterations are strongly associated with the development of cancer. The aim of this study was to identify epigenetic pattern in squamous cell lung cancer (LUSC) on a genome-wide scale. RESULTS: Here we performed DNA methylation profiling on 24 LUSC and paired non-tumor lung (NTL) tissues by Illumina Human Methylation 450 K BeadArrays, and identified 5214 differentially methylated probes. By integrating DNA methylation and mRNA expression data, 449 aberrantly methylated genes accompanied with altered expression were identified. Ingenuity Pathway analysis highlighted these genes which were closely related to the carcinogenesis of LUSC, such as ERK family, NFKB signaling pathway, Hedgehog signaling pathway, providing new clues for understanding the molecular mechanisms of LUSC pathogenesis. To verify the results of high-throughput screening, we used 56 paired independent tissues for clinical validation by pyrosequencing. Subsequently, another 343 tumor tissues from the Cancer Genome Atlas (TCGA) database were utilized for further validation. Then, we identified a panel of DNA methylation biomarkers (CLDN1, TP63, TBX5, TCF21, ADHFE1 and HNF1B) in LUSC. Furthermore, we performed receiver operating characteristics (ROC) analysis to assess the performance of biomarkers individually, suggesting that they could be suitable as potential diagnostic biomarkers for LUSC. Moreover, hierarchical clustering analysis of the DNA methylation data identified two tumor subgroups, one of which showed increased DNA methylation. CONCLUSIONS: Collectively, these results suggest that DNA methylation plays critical roles in lung tumorigenesis and may potentially be proposed as a diagnostic biomarker.

However, biogeographic and phylogeographic information of termites of this region is limited compared to other world geographic regions. Nasutitermes corniger is widely distributed in the region and is of considerable economic importance. The goal of this study was to describe the phylogeography of N. corniger in the Neotropical Region, to better understand its evolutionary processes. RESULTS: The sampled populations of N. corniger showed high genetic variation. Results indicated strong geographic structure among N. corniger populations, with most haplotypes not broadly shared among separated locations. Phylogeographic analyses showed a dispersal route for N. corniger from Central America into South America via the Isthmus of Panama, with subsequent dispersal through the highlands east of the Andes and into eastern regions of the continent. The majority of haplotypes were limited in distribution to proximal regions, corresponding to particular biomes (Atlantic Forest, Amazonia, Chaco, Cerrado and Caatinga). CONCLUSIONS: Nasutitermes corniger is suggested to be a good model for biogeographic and phylogeographic studies in the Neotropical Region. This study clarified the phylogeographic history of N. corniger and can contribute to the understanding of biogeographic dispersion processes in the Neotropical Region.

AB - BACKGROUND: The Aspergillus niger genome contains a large repertoire of genes encoding carbohydrate active enzymes (CAZymes) that are targeted to plant polysaccharide degradation enabling A. niger to grow on a wide range of plant biomass substrates. Which genes need to be activated in certain environmental conditions depends on the composition of the available substrate. Previous studies have demonstrated the involvement of a number of transcriptional regulators in plant biomass degradation and have identified sets of target genes for each regulator. In this study, a broad transcriptional analysis was performed of the A. niger genes encoding (putative) plant polysaccharide degrading enzymes. Microarray data focusing on the initial response of A. niger to the presence of plant biomass related carbon sources were analyzed of a wild-type strain N402 that was grown on a large range of carbon sources and of the regulatory mutant strains DeltaxlnR, DeltaaraR, DeltaamyR, DeltarhaR and DeltagalX that were grown on their specific inducing compounds. RESULTS: The cluster analysis of the expression data revealed several groups of co-regulated genes, which goes beyond the traditionally described co-regulated gene sets. Additional putative target genes of the selected regulators were identified, based on their expression profile. Notably, in several cases the expression profile puts questions on the function assignment of uncharacterized genes that was based on homology searches, highlighting the need for more extensive biochemical studies into the substrate specificity of enzymes encoded by these non-characterized genes. The data also revealed sets of genes that were upregulated in the regulatory mutants, suggesting interaction between the regulatory systems and a therefore even more complex overall regulatory network than has been reported so far. CONCLUSIONS: Expression profiling on a large number of substrates provides better insight in the complex regulatory systems that drive the conversion of plant biomass by fungi. In addition, the data provides additional evidence in favor of and against the similarity-based functions assigned to uncharacterized genes. PMID- 29169321 TI - LBJMR medium: a new polyvalent culture medium for isolating and selecting vancomycin and colistin-resistant bacteria. AB - BACKGROUND: Multi-drug resistant bacteria are a phenomenon which is on the increase around the world, particularly with the emergence of colistin-resistant Enterobacteriaceae and vancomycin-resistant enterococci strains. The recent discovery of a plasmid-mediated colistin resistance with the description of the transferable mcr-1 gene raised concerns about the need for an efficient detection method for these pathogens, to isolate infected patients as early as possible. The LBJMR medium was developed to screen for all polymyxin-resistant Gram negative bacteria, including mcr-1 positive isolates, and vancomycin-resistant Gram-positive bacteria. RESULTS: The LBJMR medium was developed by adding colistin sulfate salt at a low concentration (4 MUg/mL) and vancomycin (50 MUg/mL), with glucose (7.5 g/L) as a fermentative substrate, to a Purple Agar Base (31 g/L). A total of 143 bacterial strains were used to evaluate this universal culture medium, and the sensitivity and specificity of detection were 100% for the growth of resistant strains. 68 stool samples were cultured on LBJMR, and both colistin-resistant Gram-negative and vancomycin-resistant Gram positive strains were specifically detected. CONCLUSIONS: The LBJMR medium is a multipurpose selective medium which makes it possible to identify bacteria of interest from clinical samples and to isolate contaminated patients in hospital settings. This is a simple medium that could be easily used for screening in clinical microbiology laboratories. PMID- 29169322 TI - Evidence of high-altitude adaptation in the glyptosternoid fish, Creteuchiloglanis macropterus from the Nujiang River obtained through transcriptome analysis. AB - BACKGROUND: Organisms living at high altitudes face low oxygen and temperature conditions; thus, the genetic mechanisms underlying the adaptations in these organisms merit investigation. The glyptosternoid fish, Creteuchiloglanis macropterus mainly inhabits regions with gradual increases in altitudes along the Nujiang River and might serve as an appropriate evolutionary model for detecting adaptation processes in environments with altitude changes. RESULTS: We constructed eleven RNA-sequencing (RNA-seq) libraries of C. macropterus collected from five locations at different altitudes to identify the genetic signatures of high-altitude adaptation. The comparative genomic analysis indicated that C. macropterus has an accelerated evolutionary rate compared with that of fishes in the lowland, and fishes at higher altitudes might evolve faster. Functional enrichment analysis of the fast-evolving and positively selected genes, differentially expressed genes and highly expressed genes, showed that these genes were involved in many functions related to energy metabolism and hypoxia. CONCLUSIONS: Our study provides evidence of high-altitude adaptation in C. macropterus, and the detected adaptive genes might be a resource for future investigations of adaptations to high-altitude environments in other fishes. PMID- 29169323 TI - Tol2 transposon-mediated transgenesis in the Midas cichlid (Amphilophus citrinellus) - towards understanding gene function and regulatory evolution in an ecological model system for rapid phenotypic diversification. AB - BACKGROUND: The Midas cichlid species complex (Amphilophus spp.) is widely known among evolutionary biologists as a model system for sympatric speciation and adaptive phenotypic divergence within extremely short periods of time (a few hundred generations). The repeated parallel evolution of adaptive phenotypes in this radiation, combined with their near genetic identity, makes them an excellent model for studying phenotypic diversification. While many ecological and evolutionary studies have been performed on Midas cichlids, the molecular basis of specific phenotypes, particularly adaptations, and their underlying coding and cis-regulatory changes have not yet been studied thoroughly. RESULTS: For the first time in any New World cichlid, we use Tol2 transposon-mediated transgenesis in the Midas cichlid (Amphilophus citrinellus). By adapting existing microinjection protocols, we established an effective protocol for transgenesis in Midas cichlids. Embryos were injected with a Tol2 plasmid construct that drives enhanced green fluorescent protein (eGFP) expression under the control of the ubiquitin promoter. The transgene was successfully integrated into the germline, driving strong ubiquitous expression of eGFP in the first transgenic Midas cichlid line. Additionally, we show transient expression of two further transgenic constructs, ubiquitin::tdTomato and mitfa::eGFP. Transgenesis in Midas cichlids will facilitate further investigation of the genetic basis of species specific traits, many of which are adaptations. CONCLUSION: Transgenesis is a versatile tool not only for studying regulatory elements such as promoters and enhancers, but also for testing gene function through overexpression of allelic gene variants. As such, it is an important first step in establishing the Midas cichlid as a powerful model for studying adaptive coding and non-coding changes in an ecological and evolutionary context. PMID- 29169324 TI - A post-gene silencing bioinformatics protocol for plant-defence gene validation and underlying process identification: case study of the Arabidopsis thaliana NPR1. AB - BACKGROUND: Advances in forward and reverse genetic techniques have enabled the discovery and identification of several plant defence genes based on quantifiable disease phenotypes in mutant populations. Existing models for testing the effect of gene inactivation or genes causing these phenotypes do not take into account eventual uncertainty of these datasets and potential noise inherent in the biological experiment used, which may mask downstream analysis and limit the use of these datasets. Moreover, elucidating biological mechanisms driving the induced disease resistance and influencing these observable disease phenotypes has never been systematically tackled, eliciting the need for an efficient model to characterize completely the gene target under consideration. RESULTS: We developed a post-gene silencing bioinformatics (post-GSB) protocol which accounts for potential biases related to the disease phenotype datasets in assessing the contribution of the gene target to the plant defence response. The post-GSB protocol uses Gene Ontology semantic similarity and pathway dataset to generate enriched process regulatory network based on the functional degeneracy of the plant proteome to help understand the induced plant defence response. We applied this protocol to investigate the effect of the NPR1 gene silencing to changes in Arabidopsis thaliana plants following Pseudomonas syringae pathovar tomato strain DC3000 infection. Results indicated that the presence of a functionally active NPR1 reduced the plant's susceptibility to the infection, with about 99% of variability in Pseudomonas spore growth between npr1 mutant and wild-type samples. Moreover, the post-GSB protocol has revealed the coordinate action of target-associated genes and pathways through an enriched process regulatory network, summarizing the potential target-based induced disease resistance mechanism. CONCLUSIONS: This protocol can improve the characterization of the gene target and, potentially, elucidate induced defence response by more effectively utilizing available phenotype information and plant proteome functional knowledge. PMID- 29169325 TI - Primary tumor location predicts poor clinical outcome with cetuximab in RAS wild type metastatic colorectal cancer. AB - BACKGROUND: In metastatic colorectal cancer, the location of the primary tumor has been suggested to have biological significance. In this study, we investigated whether primary tumor location affects cetuximab efficacy in patients with RAS wild-type metastatic colorectal cancer. METHODS: Genotyping by the SequenomMassARRAY technology platform (OncoMap) targeting KRAS, NRAS, PIK3CA, and BRAF was performed in tumors from 307 patients who had been given cetuximab as salvage treatment. Tumors with mutated RAS (KRAS or NRAS; n = 127) and those with multiple primary location (n = 10) were excluded. Right colon cancer was defined as a tumor located in the proximal part to splenic flexure. RESULTS: A total of 170 patients were included in the study (right versus left, 23 and 147, respectively). Patients with right colon cancer showed more mutated BRAF (39.1% vs. 5.4%), mutated PIK3CA (13% vs. 1.4%), poorly differentiated tumor (17.4% vs. 3.4%), and peritoneal involvement (26.1% vs. 8.8%) than those with left colon and rectal cancer. Right colon cancer showed poorer progression-free survival (2.0 vs.5.0 months, P = 0.002) and overall survival (4.1 months and 13.0 months, P < 0.001) than the left colon and rectal cancer. By multivariable analysis, BRAF mutation, right colon primary, poorly differentiated histology, and peritoneal involvement were associated with risk of death. CONCLUSIONS: In RAS wild-type colon cancer treated with cetuximab as salvage treatment, right colon primary was associated with poorer survival outcomes than left colon and rectal cancer. PMID- 29169326 TI - Determinants of depression in primary caregivers of disabled older relatives: a path analysis. AB - BACKGROUND: Despite the large literature analysing factors related to depression, several factors such as caregiving obligation and the interrelationships among the different variables relating to depression have been little studied. The current study aimed to analyse the effect of caregiving obligation (beliefs regarding obligation and social pressure) on depression, and the mediating effects of perceived burden on the relationship between stressors and depression, in primary caregivers of older relatives. METHODS: Cross-sectional study design. A probabilistic sample of caregivers from Spain (N = 200) was used. The data collection was conducted in 2013 through structured interviews in the caregivers' homes. The measures included sense of obligation for caregiving, perceived burden, stressors and depression. RESULTS: Depression had a direct and positive association with perceived burden, behavioural problems, and social pressure, and it was indirectly related through perceived burden to behavioural problems, independence for the activities of daily living and beliefs of obligation. CONCLUSIONS: Our results support the multidimensional concept of obligation, suggesting the existence of both an external obligation (social pressure) and an internal obligation (beliefs of obligation); (b) our findings support the hypothesis that external obligation is related to negative caregiving consequences, while internal obligation protects from these consequences; and (c) our findings support the partial mediation of stressors on depression by perceived burden. The relevance of the research to clinical practice includes the importance of understanding the perceived obligation of caregiving related to both internal and external sources of obligation. PMID- 29169328 TI - Validation and inter-rater reliability of a three item falls risk screening tool. AB - BACKGROUND: Falls screening tools are routinely used in hospital settings and the psychometric properties of tools should be examined in the setting in which they are used. The aim of this study was to explore the concurrent and predictive validity of the Austin Health Falls Risk Screening Tool (AHFRST), compared with The Northern Hospital Modified St Thomas's Risk Assessment Tool (TNH-STRATIFY), and the inter-rater reliability of the AHFRST. METHODS: A research physiotherapist used the AHFRST and TNH-STRATIFY to classify 130 participants admitted to Austin Health (five acute wards, n = 115 two subacute wards n = 15; median length of stay 6 days IQR 3-12) as 'High' or 'Low' falls risk. The AHFRST was also completed by nursing staff on patient admission. Falls data was collected from the hospital incident reporting system. RESULTS: Six falls occurred during the study period (fall rate of 4.6 falls per 1000 bed days). There was substantial agreement between the AHFRST and the TNH-STRATIFY (Kappa = 0.68, 95% CI 0.52-0.78). Both tools had poor predictive validity, with low specificity (AHFRST 46.0%, 95% CI 37.0-55.1; TNH-STRATIFY 34.7%, 95% CI 26.4 43.7) and positive predictive values (AHFRST 5.6%, 95% CI 1.6-13.8; TNH-STRATIFY 6.9%, 95% CI 2.6-14.4). The AHFRST showed moderate inter-rater reliability (Kappa = 0.54, 95% CI = 0.36-0.67, p < 0.001) although 18 patients did not have the AHFRST completed by nursing staff. CONCLUSIONS: There was an acceptable level of agreement between the 3 item AHFRST classification of falls risk and the longer, 9 item TNH-STRATIFY classification. However, both tools demonstrated limited predictive validity in the Austin Health population. The results highlight the importance of evaluating the validity of falls screening tools, and the clinical utility of these tools should be reconsidered. PMID- 29169327 TI - Comparative transcriptome analysis of oil palm flowers reveals an EAR-motif containing R2R3-MYB that modulates phenylpropene biosynthesis. AB - BACKGROUND: Oil palm is the most productive oil crop and the efficiency of pollination has a direct impact on the yield of oil. Pollination by wind can occur but maximal pollination is mediated by the weevil E. kamerunicus. These weevils complete their life cycle by feeding on male flowers. Attraction of weevils to oil palm flowers is due to the emission of methylchavicol by both male and female flowers. In search for male flowers, the weevils visit female flowers by accident due to methylchavicol fragrance and deposit pollen. Given the importance of methylchavicol emission on pollination, we performed comparative transcriptome analysis of oil palm flowers and leaves to identify candidate genes involved in methylchavicol production in flowers. RESULTS: RNA sequencing (RNA Seq) of male open flowers, female open flowers and leaves was performed using Illumina HiSeq 2000 platform. Analysis of the transcriptome data revealed that the transcripts of methylchavicol biosynthesis genes were strongly up-regulated whereas transcripts encoding genes involved in lignin production such as, caffeic acid O-methyltransferase (COMT) and Ferulate-5-hydroxylase (F5H) were found to be suppressed in oil palm flowers. Among the transcripts encoding transcription factors, an EAR-motif-containing R2R3-MYB transcription factor (EgMYB4) was found to be enriched in oil palm flowers. We determined that EgMYB4 can suppress the expression of a monolignol pathway gene, EgCOMT, in vivo by binding to the AC elements present in the promoter region. EgMYB4 was further functionally characterized in sweet basil which also produces phenylpropenes like oil palm. Transgenic sweet basil plants showed significant reduction in lignin content but produced more phenylpropenes. CONCLUSIONS: Our results suggest that EgMYB4 possibly restrains lignin biosynthesis in oil palm flowers thus allowing enhanced carbon flux into the phenylpropene pathway. This study augments our understanding of the diverse roles that EAR-motif-containing MYBs play to fine tune the metabolic flux along the various branches of core phenylpropanoid pathway. This will aid in metabolic engineering of plant aromatic compounds. PMID- 29169329 TI - Micro-costing analysis of guideline-based treatment by direct-acting agents: the real-life case of hepatitis C management in Brazil. AB - BACKGROUND: Eradication of hepatitis C virus (HCV) using direct-acting agents (DAA) has been associated with a financial burden to health authorities worldwide. We aimed to evaluate the guideline-based treatment costs by DAAs from the perspective of the Brazilian Ministry of Health (BMoH). METHODS: The activity based costing method was used to estimate the cost for monitoring/treatment of genotype-1 (GT1) HCV patients by the following strategies: peg-interferon (PEG IFN)/ribavirin (RBV) for 48 weeks, PEG-IFN/RBV plus boceprevir (BOC) or telaprevir (TEL) for 48 weeks, and sofosbuvir (SOF) plus daclastavir (DCV) or simeprevir (SIM) for 12 weeks. Costs were reported in United States Dollars without (US$) and with adjustment for purchasing power parity (PPP$). Drug costs were collected at the National Database of Health Prices and an overview of the literature was performed to assess effectiveness of SOF/DCV and SOF/SIM regimens in real-world cohorts. RESULTS: Treatment costs of GT1-HCV patients were PPP$ 43,176.28 (US$ 24,020.16) for PEG-IFN/RBV, PPP$ 71,196.03 (US$ 39,578.23) for PEG IFN/RBV/BOC and PPP$ 86,250.33 (US$ 47,946.92) for PEG-IFN/RBV/TEL. Treatment by all-oral interferon-free regimens were the less expensive approach: PPP$ 19,761.72 (US$ 10,985.90) for SOF/DCV and PPP$ 21,590.91 (US$ 12,002.75) for SOF/SIM. The overview reported HCV eradication in up to 98% for SOF/DCV and 96% for SOF/SIM. CONCLUSION: Strategies with all oral interferon-free might lead to lower costs for management of GT1-HCV patients compared to IFN-based regimens in Brazil. This occurred mainly because of high discounts over international DAA prices due to negotiation between BMoH and pharmaceutical industries. PMID- 29169330 TI - Comparing levocardia and dextrocardia in fetuses with heterotaxy syndrome: prenatal features, clinical significance and outcomes. AB - BACKGROUND: To investigate the differences in cardiovascular disease, extracardiac anomalies and outcomes between fetuses with levocardia and dextrocardia. METHODS: Clinical demographics, prenatal features, postnatal characteristics and the outcomes of fetuses with levocardia or dextrocardia were recorded and analyzed. RESULTS: Sixty-five fetuses with dextrocardia and thirty eight fetuses with levocardia were enrolled. Right ventricle outlet obstruction, atrioventricular septal defect and intestinal malrotation were common in both groups. Univentricular physiology, transposition of the great arteries and esophageal atresia were more frequent in fetuses with levocardia, whereas abnormal pulmonary venous connection, double outlet of right ventricle, left ventricle outlet obstruction and brain abnormalities were more frequent in the dextrocardia group. The accuracy of evaluating cardiac malformations was high, but the sensitivity in assessing extracardiac abnormalities was low. CONCLUSIONS: Although the disorders have certain overlapping features, there are several differences between fetuses with levocardia and dextrocardia. These findings might improve patient counseling and perinatal management. PMID- 29169331 TI - Prescription of secondary preventive drugs after ischemic stroke: results from the Malaysian National Stroke Registry. AB - BACKGROUND: Evaluation of secondary stroke prevention in low and middle-income countries remains limited. This study assessed the prescription of secondary preventive drugs among ischemic stroke patients upon hospital discharge in Malaysia and identified factors related to the prescribing decisions. METHODS: From Malaysian National Stroke Registry, we included patients with non-fatal ischemic stroke. Prescriptions of antiplatelet, anticoagulants, antihypertensive drugs and lipid-lowering drugs were assessed. Multi-level logistic regressions were performed to determine the relation between potential factors and drug prescriptions. RESULTS: Of 5292 patients, 48% received antihypertensive drugs, 88.9% antiplatelet and 88.7% lipid-lowering drugs upon discharge. Thirty-three percent of patients with an indication for anticoagulants (n = 391) received it. Compared to patients <=50 years, patients above 70 years were less likely to receive antiplatelet (OR: 0.72, 95% CI: 0.50-1.03), lipid-lowering drugs (OR: 0.66, 95% CI: 0.45-0.95) and anticoagulants (OR: 0.27, 95% CI: 0.09-0.83). Patients with moderate to severe disability upon discharge had less odds of receiving secondary preventive drugs; an odds ratio of 0.57 (95% CI: 0.45-0.71) for antiplatelet, 0.86 (95% CI: 0.75-0.98) for antihypertensive drugs and 0.78 (95% CI: 0.63-0.97) for lipid-lowering drugs in comparison to those with minor disability. Having prior specific comorbidities and drug prescriptions significantly increased the odds of receiving these drugs. No differences were found between sexes and ethnicities. CONCLUSIONS: Prescription of antihypertensive drugs and anticoagulants among ischemic stroke patients in Malaysia were suboptimal. Efforts to initiate regular clinical audits to evaluate the uptake and effectiveness of secondary preventive strategies are timely in low and middle-income settings. PMID- 29169332 TI - How does pre-dialysis education need to change? Findings from a qualitative study with staff and patients. AB - BACKGROUND: Pre-dialysis education (PDE) is provided to thousands of patients every year, helping them decide which renal replacement therapy (RRT) to choose. However, its effectiveness is largely unknown, with relatively little previous research into patients' views about PDE, and no research into staff views. This study reports findings relevant to PDE from a larger mixed methods study, providing insights into what staff and patients think needs to improve. METHODS: Semi-structured interviews in four hospitals with 96 clinical and managerial staff and 93 dialysis patients, exploring experiences of and views about PDE, and analysed using thematic framework analysis. RESULTS: Most patients found PDE helpful and staff valued its role in supporting patient decision-making. However, patients wanted to see teaching methods and materials improve and biases eliminated. Staff were less aware than patients of how informal staff-patient conversations can influence patients' treatment decision-making. Many staff felt ill equipped to talk about all treatment options in a balanced and unbiased way. Patient decision-making was found to be complex and patients' abilities to make treatment decisions were adversely affected in the pre-dialysis period by emotional distress. CONCLUSIONS: Suggested improvements to teaching methods and educational materials are in line with previous studies and current clinical guidelines. All staff, irrespective of their role, need to be trained about all treatment options so that informal conversations with patients are not biased. The study argues for a more individualised approach to PDE which is more like counselling than education and would demand a higher level of skill and training for specialist PDE staff. The study concludes that even if these improvements are made to PDE, not all patients will benefit, because some find decision-making in the pre-dialysis period too complex or are unable to engage with education due to illness or emotional distress. It is therefore recommended that pre-dialysis treatment decisions are temporary, and that PDE is replaced with on-going RRT education which provides opportunities for personalised education and on-going review of patients' treatment choices. Emotional support to help overcome the distress of the transition to end-stage renal disease will also be essential to ensure all patients can benefit from RRT education. PMID- 29169333 TI - Cultural factors associated with the intent to be screened for prostate cancer among adult men in a rural Kenyan community. AB - BACKGROUND: The aim of this study was to determine cultural factors associated with prostate cancer screening intent among adult Kenyan African men. METHODS: A cross-sectional quantitative study with an analytic design was carried out in a randomly selected sample of 155 adult men aged 25-98 years living in a rural community in Kenya. Constructs from the Theory of Planned Behaviour were used to guide this study. A 5 -point Likert scale was used to assess fatalistic beliefs, fear, perceived benefits, and family influence. A structured questionnaire was used to collect quantitative data at the household level. RESULTS: Only 2.4% of the study participants had been screened for prostate cancer. About 2/3rd (64%) of the participants felt that they were at risk of getting prostate cancer; 44% intended to be screened within the following 6 months. Mean scores on a 5-point Likert scale indicated: strong beliefs in the benefits of prostate screening (4.2 (+/-SD .8), men aged over 40 were not perceived to be at risk of getting prostate cancer (1.3 +/- .6), relatively high fatalistic beliefs of prostate cancer screening (3.6 (+/-SD .8), high degree of fear or apprehension of prostate cancer screening (3.2 (+/-SD 1.2), and a high level of influence of family members in prostate cancer screening (3.9 (+/-SD 1.0). The Wald criterion demonstrated that only family influence made a significant contribution to the intent to screen for prostate cancer (p = 0.031). Age, education, marital status, fatalism, fear, and benefit of screening were not associated with the intent to screen for prostate cancer. CONCLUSIONS: Strong beliefs of the benefits of prostate screening tended to be surpassed by relatively high fatalistic beliefs and fear or apprehension in prostate cancer screening. The family plays an important role in influencing decision making related to prostate cancer screening in Africans. PMID- 29169334 TI - Prevalence and treatment of diabetes mellitus and hypertension among older adults with intellectual disability in comparison with the general population. AB - BACKGROUND: Diabetes mellitus and hypertension are risk factors for cardiovascular disease, which is the most common cause of death in the world. People with intellectual disability (ID) have been reported to have high rates of both these disorders. The aim of this study was to describe and compare prevalence ratios of diabetes mellitus and hypertension between older adults with ID and their age peers in the general population, and to describe and compare treatment patterns in these two groups. METHODS: This is a Swedish register-based study, in which we established a cohort of people aged 55+ years and who had received support for those with ID in 2012 (n = 7936). We also established a same sized referent cohort from the general population matched by sex and year of birth. Information on diagnoses of diabetes mellitus and hypertension, and prescription of drugs for these disorders, were collected from national registers for the period 2006-2012. The two cohorts were compared using generalized linear models (GLM). RESULTS: People with ID were 20% more likely than the general population to have a diagnosis of diabetes mellitus, and 26% more likely to have prescription of drugs for diabetes mellitus. People in the general population were 81% more likely to have a diagnosis of hypertension, and 9% more likely to have a prescription of drugs for hypertension. Among those with diabetes, ID was associated with higher occurrence of prescription of insulin combination drugs and sulfonylureas, but lower occurrence of prescription of dipeptidyl peptidase (DPP) 4-inhibitors and exenatide/liraglutide. Among those with hypertension, ID was associated with higher occurrence of prescription of diuretics, but lower occurrence of prescription of calcium channel blockers and angiotensin II antagonists. CONCLUSIONS: Treatment regimens among people with ID tended to include older types of medication compared with what was prescribed in the general population. To ensure that this is medically appropriate and not due to failure to update the treatment regimen, it is important to investigate if the people with ID and diabetes mellitus or hypertension are subjected to the same regular drug reviews that are recommended for older adults in general. PMID- 29169335 TI - Patient- and treatment-related risk factors associated with neck muscle spasm in nasopharyngeal carcinoma patients after intensity-modulated radiotherapy. AB - BACKGROUND: To evaluate the incidence of neck muscle spasm in nasopharyngeal carcinoma (NPC) patients that received intensity-modulated radiotherapy (IMRT), and to analyse the patient- and treatment-related risk factors associated with neck muscle spasm. METHODS: A sample of 152 IMRT-treated, biopsy-proven, nondisseminated NPC patients were retrospectively analysed. All had documented IMRT treatment plans and had returned for follow-up review at 4 years post radiotherapy. Spasm of the sternocleidomastoid (SCM) muscle was graded from 0 to 3 (absent to severe) and this grade served as the clinical endpoint. Risk factors were identified using logistic regression analysis. RESULTS: Within 4 years of radiotherapy, neck muscle spasm developed in 23.68% of the patients; Grades 0, 1, 2 and 3 were respectively assigned to 83.55, 7.57, 6.58 and 2.30% of assessed SCMs. Multivariate analysis indicated that gender, N stage, V60 (percentage of SCM volume that received >60 Gy) were independent prognostic variables, and that the optimal threshold for using V60 to predict neck muscle spasm was 61.92% (sensitivity = 0.900, specificity = 0.953). CONCLUSIONS: Gender, N stage and V60 were independent predictive factors for post-radiotherapy neck muscle spasm, and a V60 of <=61.92% in the SCM was relatively safe. PMID- 29169336 TI - Multi-region and single-cell sequencing reveal variable genomic heterogeneity in rectal cancer. AB - BACKGROUND: Colorectal cancer is a heterogeneous group of malignancies with complex molecular subtypes. While colon cancer has been widely investigated, studies on rectal cancer are very limited. Here, we performed multi-region whole exome sequencing and single-cell whole-genome sequencing to examine the genomic intratumor heterogeneity (ITH) of rectal tumors. METHODS: We sequenced nine tumor regions and 88 single cells from two rectal cancer patients with tumors of the same molecular classification and characterized their mutation profiles and somatic copy number alterations (SCNAs) at the multi-region and the single-cell levels. RESULTS: A variable extent of genomic heterogeneity was observed between the two patients, and the degree of ITH increased when analyzed on the single cell level. We found that major SCNAs were early events in cancer development and inherited steadily. Single-cell sequencing revealed mutations and SCNAs which were hidden in bulk sequencing. In summary, we studied the ITH of rectal cancer at regional and single-cell resolution and demonstrated that variable heterogeneity existed in two patients. The mutational scenarios and SCNA profiles of two patients with treatment naive from the same molecular subtype are quite different. CONCLUSIONS: Our results suggest each tumor possesses its own architecture, which may result in different diagnosis, prognosis, and drug responses. Remarkable ITH exists in the two patients we have studied, providing a preliminary impression of ITH in rectal cancer. PMID- 29169338 TI - Anger management in substance abuse based on cognitive behavioral therapy: an interventional study. AB - BACKGROUND: Anger and aggression have been developing notably in societies, especially among patients depending on substance abuse. Therefore, this study aimed to investigate the effect of anger management based on group education among patients depending on substances according to Patrick Reilly's cognitive behavioral approach. METHODS: In a quasi- experimental study, all patients who met the inclusion criteria were evaluated regarding their aggression level. The participants were assigned to 12 educational sessions based on group therapy and Patrick-Reilly's anger management by focusing on using a combination of cognitive intervention, relaxation, and communication skills. The data were analyzed using the SPSS statistical software, version 16. RESULTS: The findings showed a significant difference between the two groups regarding aggression level after the intervention (p = 0.001). No significant relationship was observed between aggression level and demographic variables (p > 0.05). CONCLUSION: The intervention of this study can be used for establishing self-management and decreasing anger among patients depending on substances. They can also be used as a therapeutic program in addition to pharmacotherapy. TRIAL REGISTRATION: IRCT2016102030398N1 . PMID- 29169337 TI - Minimally invasive pancreaticoduodenectomy for periampullary disease: a comprehensive review of literature and meta-analysis of outcomes compared with open surgery. AB - BACKGROUND: Minimally invasive pancreatoduodenectomy (MIPD) has been gradually attempted. However, whether MIPD is superior, equal or inferior to its conventional open pancreatoduodenectomy (OPD) is not clear. METHODS: Studies published up to May 2017 were searched in PubMed, Embase, Cochrane Library, and Web of Science. Main outcomes were comprehensively reviewed and measured including conversion to open approach, operation time (OP), estimated blood loss (EBL), transfusion, length of hospital stay (LOS), overall complications, postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), post pancreatectomy hemorrhage (PPH), readmission, reoperation and reasons of preoperative death, number of retrieved lymph nodes (RLN), surgical margins, recurrence, and survival. The software of Review Manage version 5.1 was used for meta-analysis. RESULTS: One hundred studies were included for systematic review and 26 out of them (totally 3402 cases, 1064 for MIPD, 2338 for OPD) were included for meta-analysis. In the early years, most articles were case reports or non-control case series studies, while in the last 6 years high-volume and comparative researches were increasing gradually. Systematic review revealed conversion rates of MIPD to OPD ranged from 0% to 40%. The mean or median OP of MIPD ranged from 276 to 657 min. The total POPF rates vary between 3.8% and 50% observed in all systematic reviewed studies. Meta-analysis demonstrated MIPD had longer OP (WMD = 99.4 min; 95%CI: 46.0 ~ 152.8, P < 0.01), lower blood loss (WMD = -0.54 ml; 95% CI, -0.88 ~ -0.20 ml; P < 0.01), lower transfusion rate (RR = 0.73, 95%CI: 0.57 ~ 0.94, P = 0.02), shorter LOS (WMD = -3.49 days; 95%CI: -4.83 ~ -2.15, P < 0.01). There was no significant difference in time to oral intake, postoperative complications, POPF, reoperation, readmission, perioperative mortality and number of retrieved lymph nodes. CONCLUSION: Our study demonstrates MIPD is technically feasible and safety on the basis of historical studies. MIPD is associated with less blood loss, faster postoperative recovery, shorter length of hospitalization and longer operation time. These findings are waiting for being confirmed with robust prospective comparative studies and randomized clinical trials. PMID- 29169339 TI - An orthotopic xenograft model for high-risk non-muscle invasive bladder cancer in mice: influence of mouse strain, tumor cell count, dwell time and bladder pretreatment. AB - BACKGROUND: Novel theranostic options for high-risk non-muscle invasive bladder cancer are urgently needed. This requires a thorough evaluation of experimental approaches in animal models best possibly reflecting human disease before entering clinical studies. Although several bladder cancer xenograft models were used in the literature, the establishment of an orthotopic bladder cancer model in mice remains challenging. METHODS: Luciferase-transduced UM-UC-3LUCK1 bladder cancer cells were instilled transurethrally via 24G permanent venous catheters into athymic NMRI and BALB/c nude mice as well as into SCID-beige mice. Besides the mouse strain, the pretreatment of the bladder wall (trypsin or poly-L lysine), tumor cell count (0.5 * 106-5.0 * 106) and tumor cell dwell time in the murine bladder (30 min - 2 h) were varied. Tumors were morphologically and functionally visualized using bioluminescence imaging (BLI), magnetic resonance imaging (MRI), and positron emission tomography (PET). RESULTS: Immunodeficiency of the mouse strains was the most important factor influencing cancer cell engraftment, whereas modifying cell count and instillation time allowed fine tuning of the BLI signal start and duration - both representing the possible treatment period for the evaluation of new therapeutics. Best orthotopic tumor growth was achieved by transurethral instillation of 1.0 * 106 UM-UC-3LUCK1 bladder cancer cells into SCID-beige mice for 2 h after bladder pretreatment with poly-L-lysine. A pilot PET experiment using 68Ga-cetuximab as transurethrally administered radiotracer revealed functional expression of epidermal growth factor receptor as representative molecular characteristic of engrafted cancer cells in the bladder. CONCLUSIONS: With the optimized protocol in SCID-beige mice an applicable and reliable model of high-risk non-muscle invasive bladder cancer for the development of novel theranostic approaches was established. PMID- 29169340 TI - Situational analysis of antibiotic use and resistance in Ghana: policy and regulation. AB - BACKGROUND: Antibiotics have played an essential role in decreasing morbidity and mortality from infectious diseases. However, indiscriminate use and unrestricted access is contributing to the emergence of bacterial resistance. This paper reports on a situational analysis of antimicrobial use and resistance in Ghana, with focus on policy and regulation. METHODS: Relevant policy documents, reports, regulations and enactments were reviewed. PubMed and Google search engines were used to extract relevant published papers. Websites of stakeholders such as Ministry of Health (MOH) and its agencies were also reviewed. An interview guide was used to elicit responses from selected officials from these sectors. RESULTS: Laws and guidelines to control the use of antimicrobials in humans were available but not for animals. There was no National Antimicrobial Policy (NAP). A health practice regulatory law mandates Physicians, Physician Assistants, Midwives and trained Nurses to prescribe antimicrobials. However, antibiotics are widely prescribed and dispensed by unauthorised persons, suggesting weak enforcement of the laws. Antibiotics were also supplied to and from unapproved medicine outlets. The Standard Treatment Guidelines (STG), Essential Medicines List (EML) and the National Health Insurance Scheme Medicines List (NHISML) provide restrictions regarding levels of prescribing of antimicrobials. However, existing guidelines on antibiotic use are mostly not adhered to. The use of Automatic Stop Orders to avoid wastage in the hospitals is also not practiced. Data on use of antibiotics for individuals are not readily available in most facilities. Again, there are no standards or guidelines on veterinary use of antibiotics. Surveillance systems for consumption of antibiotics and resistance monitoring were not in place in most health facilities. However, there is an ongoing national action to create awareness on bacteria resistance, strengthening knowledge through research and surveillance and development of NAP in line with global action plan on antimicrobial resistance. CONCLUSION: Absence of national antimicrobial policy, weak regulatory environment and non-adherence to practice standards may have contributed to increased and unregulated access to antimicrobials in Ghana, a catalyst for development and spread of antimicrobial resistance. PMID- 29169341 TI - Prevalence, genetic variants and clinical implications of G-6-PD deficiency in Burkina Faso: a systematic review. AB - BACKGROUND: It is now well-known that some antimalarials such as primaquine may induce severe hemolytic anemia in people with G-6-PD deficiency. Antimalarial drug prescriptions must, therefore take into account the patient's G-6-PD status in malaria endemic areas such as Burkina Faso, where the prevalence of this genetic abnormality is relatively high. Although great clinical heterogeneity is observed depending on the molecular nature of the deficiency and the residual enzyme activity in the red blood cell, there is very poor data on the prevalence of G-6-PD deficiency and the distribution of involved genetic variants in Burkina Faso. In this systematic review, we present a synthesis of the various studies carried out on the G-6-PD deficiency in Burkina Faso in order to determine its prevalence, probable distribution of the genetic variants involved and their clinical implications for a national systematic screening policy among the groups most vulnerable to malaria. METHODS: A systematic review was carried out to analyze available published data on the prevalence, phenotypes and mutations responsible for G-6-PD deficiency in Burkina Faso. The key words used were "G-6 PD deficiency AND Burkina Faso" or "Deficit en G-6-PD AND Burkina Faso" in French. To identify the relevant articles, two independent reviewers reviewed the titles, abstracts and the full text of the selected papers. RESULTS: An average prevalence of 16.6% (183/1100; CI 95%: 0.145-0.190) and 6.5% (69/1066; CI 95%: 0.051-0.081) of G-6-PD deficiency was found respectively in men and women in this systematic review. Although the predominance (99.8% of G-6-PD deficient cases) of 202A/376G G-6-PD A- variant, the Santamaria and Betica Selma variants were identified in Burkina Faso. Independently of the method used, the enzymatic deficiency was significantly higher in males (2.5-20.5%) compared to females (3.3 12.3%). CONCLUSION: This systematic review suggests that despite the ubiquity of the 202A/376G G-6-PD A- variant in Burkina Faso, it will be necessary to consider the Santamaria and Betica Selma variants although their frequencies remain to be specified. A systematic screening of the G-6-PD deficiency is also needed to prevent the occurrence of iatrogenic hemolytic accidents. PMID- 29169342 TI - MVQTLCIM: composite interval mapping of multivariate traits in a hybrid F1 population of outbred species. AB - BACKGROUND: With the plummeting cost of the next-generation sequencing technologies, high-density genetic linkage maps could be constructed in a forest hybrid F1 population. However, based on such genetic maps, quantitative trait loci (QTL) mapping cannot be directly conducted with traditional statistical methods or tools because the linkage phase and segregation pattern of molecular markers are not always fixed as in inbred lines. RESULTS: We implemented the traditional composite interval mapping (CIM) method to multivariate trait data in forest trees and developed the corresponding software, mvqtlcim. Our method not only incorporated the various segregations and linkage phases of molecular markers, but also applied Takeuchi's information criterion (TIC) to discriminate the QTL segregation type among several possible alternatives. QTL mapping was performed in a hybrid F1 population of Populus deltoides and P. simonii, and 12 QTLs were detected for tree height over 6 time points. The software package allowed many options for parameters as well as parallel computing for permutation tests. The features of the software were demonstrated with the real data analysis and a large number of Monte Carlo simulations. CONCLUSIONS: We provided a powerful tool for QTL mapping of multiple or longitudinal traits in an outbred F1 population, in which the traditional software for QTL mapping cannot be used. This tool will facilitate studying of QTL mapping and thus will accelerate molecular breeding programs especially in forest trees. The tool package is freely available from https://github.com/tongchf /mvqtlcim. PMID- 29169343 TI - "What do you know?"--knowledge among village doctors of lead poisoning in children in rural China. AB - BACKGROUND: This study evaluates the extent of village doctors' knowledge of lead poisoning in children in rural China and assesses the characteristics associated with possessing accurate knowledge. METHODS: A cross-sectional, questionnaire based survey of 297 village doctors in Fenghuang County, Hunan Province, China was conducted. All village doctors were interviewed face-to-face using a "What do you know" test questionnaire focusing on prevention strategies and lead sources in rural children. RESULTS: A total of 287 (96.6%) village doctors completed the survey in full. Most village doctors had an appropriate degree of general knowledge of lead poisoning; however, they had relatively poor knowledge of lead sources and prevention measures. Village doctors with an undergraduate level education scored an average of 2.7 points higher than those who had a junior college level education (p = 0.033). Village doctors with an annual income <= 10,000 RMB yuan scored 1.03 points lower than those whose income was >10,001 RMB yuan. Ethnic Han village doctors scored 1.12 points higher, on average, than ethnic Tujia village doctors (p = 0.027). CONCLUSIONS: This study identified important gaps in knowledge concerning lead poisoning in children among a rural population of village doctors. There is a clear need for multifaceted interventions that target village doctors to improve their knowledge regarding lead poisoning in children. The "What do you know" questionnaire is a new tool to evaluate lead poisoning knowledge and education projects. PMID- 29169344 TI - Genome-wide association mapping of black point reaction in common wheat (Triticum aestivum L.). AB - BACKGROUND: Black point is a serious threat to wheat production and can be managed by host resistance. Marker-assisted selection (MAS) has the potential to accelerate genetic improvement of black point resistance in wheat breeding. We performed a genome-wide association study (GWAS) using the high-density wheat 90 K and 660 K single nucleotide polymorphism (SNP) assays to better understand the genetic basis of black point resistance and identify associated molecular markers. RESULTS: Black point reactions were evaluated in 166 elite wheat cultivars in five environments. Twenty-five unique loci were identified on chromosomes 2A, 2B, 3A, 3B (2), 3D, 4B (2), 5A (3), 5B (3), 6A, 6B, 6D, 7A (5), 7B and 7D (2), respectively, explaining phenotypic variation ranging from 7.9 to 18.0%. The highest number of loci was detected in the A genome (11), followed by the B (10) and D (4) genomes. Among these, 13 were identified in two or more environments. Seven loci coincided with known genes or quantitative trait locus (QTL), whereas the other 18 were potentially novel loci. Linear regression showed a clear dependence of black point scores on the number of favorable alleles, suggesting that QTL pyramiding will be an effective approach to increase resistance. In silico analysis of sequences of resistance-associated SNPs identified 6 genes possibly involved in oxidase, signal transduction and stress resistance as candidate genes involved in black point reaction. CONCLUSION: SNP markers significantly associated with black point resistance and accessions with a larger number of resistance alleles can be used to further enhance black point resistance in breeding. This study provides new insights into the genetic architecture of black point reaction. PMID- 29169345 TI - The antioxidant effects of riluzole on the APRE-19 celll model injury-induced by t-BHP. AB - BACKGROUND: Age-related macular degeneration (AMD) causes the dysfunction of the retinal pigment epithelial (RPE) cells. In this study, we examined the effects of riluzole, a sustained activator of the TRAAK potassium channel, on human RPE (ARPE-19) cells in an oxidant-induced cell-injury model and elucidate the mechanism of riluzole on RPE cell apoptosis. METHODS: The follow four groups of ARPE-19 cells were treated with riluzole and/or tert-butyl hydroperoxide (t-BHP) for 24.0 h: control, t-BHP, riluzole, and t-BHP + riluzole. Cell apoptosis was measured by flow cytometry, and Western blotting was performed to analyze the expression of the weakly inward rectifying potassium (TRAAK) channel. Finally, the mitochondrial membrane potential (Deltapsim) was detected by flow cytometry, and cytochrome C (Cyt-c) release was assessed by Western blotting. RESULTS: The viability of the cells in the cotreated group was significantly higher (85.6 +/- 3.1%) than that in the t-BHP group (66.2 +/- 2.5%). In addition, the cells in the cotreated group had a higher effect on increasing the expression of TRAAK than the t-BHP group. The results also showed that Cyt-c translocation significantly decreased and Deltapsim increased in the cotreated group. CONCLUSIONS: These results demonstrate that riluzole protects RPE cells from apoptosis. The protection mechanism of riluzole could be from stabilizing mitochondrial Deltapsim and preventing the release of Cyt-c. Changes in TRAAK expression might also contribute to the protection of RPE cells. PMID- 29169347 TI - Intermediate PSA half-life after neoadjuvant hormone therapy predicts reduced risk of castration-resistant prostate cancer development after radical prostatectomy. AB - BACKGROUND: The magnitude and rapidity of the tumor response to androgen deprivation is known to predict the durability of the therapy. We have investigated the predictive value of categorizing patients by the half-life of PSA under neoadjuvant androgen deprivation therapy in patients with biochemical recurrence after radical prostatectomy. METHODS: Medical records of 317 patients who received neoadjuvant androgen deprivation therapy before radical prostatectomy and developed biochemical recurrence were analyzed. The patients were categorized into five groups according to PSA half-life. Risk of developing castration resistance was evaluated by Kaplan-Meier analysis and by Cox proportional risk regression analysis. RESULTS: The median follow-up duration was 50.1 months (IQR 31.8-68.7) and median PSA half-life was 22.1 days (IQR 12.7 38.4). Comparison of survival curves revealed that patients in the intermediate response group showed significantly lower 5-year castration-resistant prostate cancer rate (37.5%) compared to non-response and ultra-rapid response groups (63.6%, p = 0.007; 56.1%, p = 0.031; respectively). In the multivariate regression model, intermediate response compared to non-response was associated with significantly reduced risk of castration resistance development (hazard ratio 0.397, 95% confidence interval 0.191-0.823, p = 0.013) and overall mortality (hazard ratio 0.138, 95% confidence interval 0.033-0.584, p = 0.007). When subcategorized by Gleason score, Kaplan-Meier curve revealed that, in the high Gleason score stratum, 5-year castration-resistant prostate cancer rate for intermediate response group (44.0%) was exceptionally lower than that in non response group (66.7%, p = 0.047), while castration resistance increased in other groups. CONCLUSION: Short PSA half-life as well as no response after androgen deprivation is associated with increased risk of treatment failure compared to intermediate PSA half-life. PMID- 29169346 TI - Social and clinical determinants of preferences and their achievement at the end of life: prospective cohort study of older adults receiving palliative care in three countries. AB - BACKGROUND: Achieving choice is proposed as a quality marker. But little is known about what influences preferences especially among older adults. We aimed to determine and compare, across three countries, factors associated with preferences for place of death and treatment, and actual site of death. METHODS: We recruited adults aged >=65-years from hospital-based multiprofessional palliative care services in London, Dublin, New York, and followed them for >17 months. All services offered consultation on hospital wards, support for existing clinical teams, outpatient services and received funding from their National Health Service and/or relevant Insurance reimbursements. The New York service additionally had 10 inpatient beds. All worked with and referred patients to local hospices. Face-to-face interviews recorded most and least preferred place of death, treatment goal priorities, demographic and clinical information using validated questionnaires. Multivariable and multilevel analyses assessed associated factors. RESULTS: One hundred and thirty eight older adults (64 London, 59 Dublin, 15 New York) were recruited, 110 died during follow-up. Home was the most preferred place of death (77/138, 56%) followed by inpatient palliative care/hospice units (22%). Hospital was least preferred (35/138, 25%), followed by nursing home (20%) and home (16%); hospice/palliative care unit was rarely least preferred (4%). Most respondents prioritised improving quality of life, either alone (54%), or equal with life extension (39%); few (3%) chose only life extension. There were no significant differences between countries. Main associates with home preference were: cancer diagnosis (OR 3.72, 95% CI 1.40 9.90) and living with someone (OR 2.19, 1.33-3.62). Adults with non-cancer diagnoses were more likely to prefer palliative care units (OR 2.39, 1.14-5.03). Conversely, functional independence (OR 1.05, 1.04-1.06) and valuing quality of life (OR 3.11, 2.89-3.36) were associated with dying at home. There was a mismatch between preferences and achievements - of 85 people who preferred home or a palliative care unit, 19 (25%) achieved their first preference. CONCLUSION: Although home is the most common first preference, it is polarising and for 16% it is the least preferred. Inpatient palliative care unit emerges as the second most preferred place, is rarely least preferred, and yet was often not achieved for those who wanted to die there. Factors affecting stated preferences and met preferences differ. Available services, notably community support and palliative care units, require expansion. Contrasting actual place of death with capacity for meeting patient and family needs may be a better quality indicator than simply 'achieved preferences'. PMID- 29169348 TI - Inpatient satisfaction with medical information received from caregivers: an observational study on the effect of social deprivation. AB - BACKGROUND: The main objective of this study was to explore the relationships between inpatients' social differentiation and satisfaction with the medical information delivered by caregivers. METHODS: In four departments of a teaching hospital, patients were enrolled as well as their attending physician and one of the nurses assigned to them. Structured survey questionnaires were administered face-to-face to patients and caregivers. Patients were asked to rate their satisfaction with the medical information received, the quality and duration of the interactions with the caregivers, and their experience regarding their involvement in medical decision-making. Caregivers were asked to rate their perception of the patients' social position and involvement in medical decision making. Social deprivation was assessed using the EPICES score in particular. The statistical analysis was mainly descriptive and completed by a structural equation model. RESULTS: A sample of 255 patients, 221 pairs of patient-physician and 235 pairs of patient-nurse were considered. One third of the patients (32.7%) were identified as socially deprived. They were significantly less satisfied with the information they received on their health status or their treatment; 56.7% of patients thought that they received sufficient explanations without having to ask. This proportion was significantly lower in socially deprived patients (42.3%) compared to not deprived patients (63.6%, p < 0.01). Patients' reported involvement in medical decision-making was significantly lower for socially deprived patients (75.0% vs 89.0%, p < 0.001). The structural equation model showed that the main determinant of patients' satisfaction regarding medical information was their perceived involvement in informed medical decision-making (CFI = 0.998, RMSEA = 0.022). CONCLUSIONS: These findings suggest that physicians and nurses need training on communication targeted towards vulnerable patients, in order to improve the accessibility of medical information, and thus to reduce health inequalities. PMID- 29169349 TI - Anticholinesterase and antioxidant potentials of Nonea micrantha Bioss. & Reut along with GC-MS analysis. AB - BACKGROUND: Nonea micrantha Boiss. & Reut . being an unexplored member of Boraginaceae was investigated for GC/MS analysis, acetylcholinesterase (AChE), butyrylcholinesterase (BChE) inhibitory and antioxidant activities in an attempt to find its effectiveness in neurological disorders. METHODS: The AChE and BChE inhibitory activities of crude methanolic extract (Nm.Cr), subsequent fractions; n-hexane (Nm.Hex), chloroform (Nm.Cf), ethyl acetate (Nm.EtAc), aqueous (Nm.Aq) and crude saponins (Nm.Sp) from N. micrantha were conducted using Ellman's assay. The antioxidant activity of the plant samples using DPPH and ABTS free radical scavenging potential following quantitative spectrophotometric and qualitative TLC method were also studied. Moreover the total reducing power (TRP) of all the samples was also figured out. RESULTS: The GC/Ms analysis confirmed that the plant is rich in bioactive molecules. Among different fractions, Nm.Hex, Nm.EtAc and Nm.Cf exhibited highest AChE inhibitory activities causing 75.51 +/- 0.73, 68.54 +/- 0.59 and 63.48 +/- 0.59% enzyme inhibition respectively and IC50 of 44, 100 and 144 MUg/mL respectively. In BChE inhibiton assay, Nm.Aq, Nm.Sp and Nm.Cr showed highest activity causing 83.49 +/- 0.27, 81.49 +/- 0.89 and 75.31 +/- 0.56% enzyme inhibition with IC50 of 90, 110 and 44 MUg/mL respectively. In DPPH assay, Nm.Aq, Nm.Cf, Nm.Hex and Nm.Cr were most potent exhibiting IC50 values of 3, 5, 93 and 120 MUg/ml respectively. In ABTS assay Nm.EtAc, Nm.Aq, Nm.Sp and Nm.Cr showed IC50 values of 60, 95, 100 and 150 MUg/mL respectively. Likewise ABTS inhibition was most prominent for Nm.Sp, Nm.EtAc and Nm.Aq causing 78.26 +/- 0.49, 67.67 +/- 0.73 and 63.58 +/- 0.45% inhibition respectively at 1 mg/mL. These results were further confirmed by qualitative screening using DPPH and ABTS staining. CONCLUSIONS: Our anticholinesterase and antioxidant results signify the N. micrantha as a potential source of natural bioactive compounds. Moreover isolation of natural bioactive compounds from this plant may lead to novel drug candidates against neurodegenerative disorders. PMID- 29169350 TI - "What say ye gout experts?" a content analysis of questions about gout posted on the social news website Reddit. AB - BACKGROUND: Social media is increasingly used by patients to source information for managing chronic disease. The aim of this study was to understand patient information needs about gout by a content analysis of questions posted on the social news website Reddit. METHODS: We analysed questions posted onto the 'Gout sufferers unite' subreddit site. Two reviewers coded questions into categories (inter-reviewer kappa 0.70), with discordant coding resolved by a third reviewer. Data were analysed by calculating the frequency of questions within the categories. Where relevant, categories were further separated into sub-categories to allow organisation and interpretation of the data. RESULTS: We analysed 359 questions in 287 posts by 213 individuals. A wide range of questions arose. The single most common category related to uncertainty of diagnosis (22.3% questions), with questions about disease management common. Information-seeking about medications was generally cautious, with questions about side-effects, risk of flares after starting urate-lowering therapy, and decision to start urate lowering therapy. Community users experiencing flares posted questions about flare management, including medications, sometimes in real-time. Dietary management questions included the effectiveness of dietary changes as a management strategy, choice of alcoholic beverage, and weight loss strategies. Questions about serum urate levels were rare (2.8% questions). CONCLUSIONS: Questions about gout posted on the subreddit site most often related to uncertainty about symptoms and disease management strategies, with infrequent questions about serum urate testing, results or targets. These findings may inform development of strategies to address the information needs of people with gout. PMID- 29169351 TI - "We have been forced to move away from home": print news coverage of Canadians studying abroad at Caribbean offshore medical schools. AB - BACKGROUND: Canadian international medical graduates are Canadian-citizens who have graduated from a medical school outside of Canada or the United States. A growing number of Canadians enroll in medical school abroad, including at Caribbean offshore medical schools. Often, Canadians studying medicine abroad attempt to return to Canada for postgraduate residency training and ultimately to practice. METHODS: The authors conducted a qualitative media analysis to discern the dominant themes and ideologies that frame discussion of offshore medical schools, and the Canadian medical students they graduate, in the Canadian print news. We carried out structured searches on Canadian Newsstand Database for print media related to offshore medical schools. RESULTS: Canadian news articles used two frames to characterize offshore medical schools and the Canadian international medical graduates they train: (1) increased opportunity for medical education for Canadians; and (2) frustration returning to Canada to practice despite domestic physician shortages. CONCLUSION: Frames deployed by the Canadian print media to discuss Caribbean offshore medical schools and Canadians studying abroad define two problems: (1) highly qualified Canadians are unable to access medical school in Canada; and (2) some Canadian international medical graduates are unable to return to Canada to practice medicine. Caribbean offshore medical schools are identified as a solution to the first problem while playing a central role in creating the second problem. These frames do not acknowledge that medical school admissions are a primary means to control the make-up of the Canadian physician workforce and they do not address the nature of Canadian physician shortages. PMID- 29169352 TI - Arthroscopic internal drainage and cystectomy of popliteal cyst in knee osteoarthritis. AB - BACKGROUND: The purpose of this study was to evaluate the efficacy of arthroscopic knee cavity internal drainage and cyst cavity debridement operation of popliteal cyst in knee osteoarthritis patients. METHODS: From August 2007 to March 2013, 58 knee osteoarthritis patients with popliteal cyst were treated with arthroscopic knee cavity internal drainage through posteromedial portal and popliteal cyst cavity debridement through superior posteromedial portal. In all patients, preoperative magnetic resonance imaging (MRI) was performed to detect combined intra-articular pathology and the communication between popliteal cyst and knee cavity. Clinical efficacy was evaluated through VAS score and Lysholm score. RESULTS: All patients had neither recurrence of popliteal cyst nor complaints of pain, swelling, or functional impairment at average 24 months follow-up after surgery. Postoperatively, VAS score was decreased significantly and Lysholm score was raised significantly comparing preoperatively. CONCLUSION: Arthroscopic knee cavity internal drainage operation through posteromedial portal and popliteal cyst cavity debridement through superior posteromedial portal is an effective minimally invasive surgery method for the treatment of popliteal cyst without recurrence in knee osteoarthritis patients. PMID- 29169353 TI - Correction to: Long-term patient reported outcomes following radiation therapy for oropharyngeal cancer: cross-sectional assessment of a prospective symptom survey in patients >=65 years old. AB - In the original publication [1] the name of author Jeremy M. Aymard was spelled wrong. The original article was updated to rectify this error. PMID- 29169354 TI - Development of a novel Newcastle disease virus (NDV) neutralization test based on recombinant NDV expressing enhanced green fluorescent protein. AB - BACKGROUND: Newcastle disease is one of the most important infectious diseases of poultry, caused by Newcastle disease virus (NDV). This virus is distributed worldwide and it can cause severe economic losses in the poultry industry due to recurring outbreaks in vaccinated and unvaccinated flocks. Protection against NDV in chickens has been associated with development of humoral response. Although hemagglutination inhibition (HI) assay and ELISA do not corroborate the presence of neutralizing antibodies (nAbs); they are used to measure protection and immune response against NDV. METHODS: In this study, we established a system to recover a recombinant NDV (rLS1) from a cloned cDNA, which is able to accept exogenous genes in desired positions. An enhanced green fluorescent protein (eGFP) gene was engineered in the first position of the NDV genome and we generated a recombinant NDV carrying eGFP. This NDV- eGFP reporter virus was used to develop an eGFP based neutralization test (eGFP-NT), in which nAbs titers were expressed as the reciprocal of the highest dilution that expressed the eGFP. RESULTS: The eGFP-NT gave conclusive results in 24 h without using any additional staining procedure. A total of 57 serum samples were assayed by conventional neutralization (NT) and eGFP-NT. Additionally, HI and a commercial ELISA kit were evaluated with the same set of samples. Although HI (R 2 = 0.816) and ELISA (R 2 = 0.791) showed substantial correlation with conventional NT, eGFP-NT showed higher correlation (R 2 = 0.994), indicating that eGFP-NT is more accurate method to quantify nAbs. CONCLUSIONS: Overall, the neutralization test developed here is a simple, rapid and reliable method for quantitation of NDV specific nAbs. It is suitable for vaccine studies and diagnostics. PMID- 29169355 TI - A comparison of liquid and solid culture for determining relapse and durable cure in phase III TB trials for new regimens. AB - BACKGROUND: Tuberculosis kills more people than any other infectious disease, and new regimens are essential. The primary endpoint for confirmatory phase III trials for new regimens is a composite outcome that includes bacteriological treatment failure and relapse. Culture methodology is critical to the primary trial outcome. Patients in clinical trials can have positive cultures after treatment ends that may not necessarily indicate relapse, which was ascribed previously to laboratory cross-contamination or breakdown of old lesions. Lowenstein-Jensen (LJ) medium was the previous standard in clinical trials, but almost all current and future trials will use the Mycobacteria Growth Indicator Tube (MGIT) system due to its simplicity and consistency of use, which will affect phase III trial results. LJ was used for the definition of the primary endpoint in the REMoxTB trial, but every culture was also inoculated in parallel into the MGIT system. The data from this trial, therefore, provide a unique opportunity to investigate and compare the incidence of false 'isolated positives' in liquid and solid media and their potential impact on the primary efficacy results. METHODS: All post-treatment positive cultures were reviewed in the REMoxTB clinical trial. Logistic regression models were used to model the incidence of isolated positive cultures on MGIT and LJ. RESULTS: A total of 12,209 sputum samples were available from 1652 patients; cultures were more often positive on MGIT than LJ. In 1322 patients with a favourable trial outcome, 126 (9.5%) had cultures that were positive in MGIT compared to 34 (2.6%) patients with positive cultures on LJ. Among patients with a favourable outcome, the incidence of isolated positives on MGIT differed by study laboratory (p < 0.0001) with 21.9% of these coming from one laboratory investigating only 4.9% of patients. No other baseline factors predicted isolated positives on MGIT after adjusting for laboratory. There was evidence of clustering of isolated positive cultures in some patients even after adjusting for laboratory, p < 0.0001. The incidence of isolated positives on MGIT did not differ by treatment arm (p = 0.845, unadjusted). Compared to negative MGIT cultures, positive MGIT cultures were more likely to be associated with higher grade TB symptoms reported within 7 days either side of sputum collection in patients with an unfavourable primary outcome (p < 0.0001) but not in patients with a favourable outcome (p = 0.481). CONCLUSIONS: Laboratory cross-contamination was a likely cause of isolated positive MGIT cultures which were clustered in some laboratories. Certain patients had repeated positive MGIT cultures that did not meet the definition of a relapse. This pattern was too common to be explained by cross-contamination only, suggesting that host factors were also responsible. We conclude that MGIT can replace LJ in phase III TB trials, but there are implications for the definition of the primary outcome and patient management in trials in such settings. Most importantly, the methodologies differ in the incidence of isolated positives and in their capacity for capturing non-tuberculosis mycobacteria. It emphasises the importance of effective medical monitoring after treatment ends and consideration of clinical signs and symptoms for determining treatment failure and relapse. PMID- 29169356 TI - Aster koraiensis extract prevents diabetes-induced retinal vascular dysfunction in spontaneously diabetic Torii rats. AB - BACKGROUND: Aster koraiensis extract (AKE) is a standard dietary herbal supplement. The aim of this study is to investigate the inhibitory effects of AKE on diabetes-induced retinal vascular dysfunction in Spontaneously Diabetic Torii (SDT) rats. METHODS: AKE (50 and 100 mg/kg body weight/day) was administered for 16 weeks. The effects of orally administered AKE on blood glucose levels, retinal vascular leakage, apoptosis, and accumulation of advanced glycation end products (AGEs) in the retina were evaluated. RESULTS: SDT rats exhibited hyperglycemia and retinal vascular leakage, and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining was clearly detected apoptosis in the retinal microvasculature. Immunofluorescence staining revealed the accumulation of AGEs in the retinal vasculature of the SDT rats. However, oral administration of AKE for 16 weeks blocked diabetes-induced blood-retinal barrier (BRB) breakdown and the loss of occludin, which is an important tight junction protein. Apoptosis of retinal vascular cells and AGE accumulation were significantly inhibited after AKE treatment. CONCLUSION: These results indicate that, as a dietary herbal supplement, AKE may have beneficial effects on patients with diabetic retinopathy. PMID- 29169357 TI - In silico design of a Zika virus non-structural protein 5 aiming vaccine protection against zika and dengue in different human populations. AB - BACKGROUND: The arboviruses Zika virus (ZIKV) and Dengue virus (DENV) have important epidemiological impact in Brazil and other tropical regions of the world. Recently, it was shown that previous humoral immunity to DENV enhances ZIKV replication in vitro, which may lead to more severe forms of the disease. Thus, traditional approaches of vaccine development aiming to control viral infection through neutralizing antibodies may induce cross-reactive enhancing antibodies. In contrast, cellular immune response was shown to be capable of controlling DENV infection independently of antibodies. The aim of the present study was to design a flavivirus NS5 protein capable of inducing a cellular immune response against DENV and ZIKV. METHODS: A consensus sequence of ZIKV NS5 protein was designed among isolates from various continents. Epitopes were predicted for the most prevalent alleles of class I and II HLA in the Brazilian population. Then, this epitopes were analyzed with regard to their conservation, population coverage and distribution along the whole antigen. RESULTS: Nineteen epitopes predicted to be more reactive (percentile rank <1) and 100% conserved among ZIKV and DENV serotypes were selected. The distribution of such epitopes along the protein was shown on a three-dimensional model and population coverage was calculated for different regions of the world. The designed protein was predicted to be stable and the distribution of selected epitopes was shown to be homogeneous along domains. The population coverage of selected epitopes was higher than 50% for most of tropical areas of the world. CONCLUSION: Such results indicate that the proposed antigen has the potential to induce protective cellular immune response to ZIKV and DENV in different human populations of the world. PMID- 29169358 TI - Risk factors for lymph node metastasis in early gastric cancer patients: Report from Eastern Europe country- Lithuania. AB - BACKGROUND: Current risk factors for lymph node metastasis in early gastric cancer have been primarily determined in Asian countries; however their applicability to Western nations is under discussion. The aim of our study was to identify risk factors associated with lymph node metastasis in Western cohort patients from the Eastern European country - Lithuania. METHODS: A total of 218 patients who underwent open gastrectomy for early gastric cancer were included in this retrospective study. After histolopathological examination, risk factors for lymph node metastasis were evaluated. Overall survival was evaluated and factors associated with long-term outcomes were analyzed. RESULTS: Lymph node metastases were present in 19.7% of early gastric cancer cases. The rates were 5/99 (4.95%) for pT1a tumors and 38/119 (31.9%) for pT1b tumors. Submucosal tumor invasion, lymphovascular invasion, and high grade tumor differentiation were identified as independent risk factors for lymph node metastasis. Submucosal tumor invasion and lymphovascular invasion were also associated with worse 5-year survival results. CONCLUSION: Our study established submucosal tumor invasion, lymphovascular invasion, and high grade tumor differentiation as risk factors for lymph node metastasis. PMID- 29169359 TI - Evaluation of a practical expert defined approach to patient population segmentation: a case study in Singapore. AB - BACKGROUND: Segmenting the population into groups that are relatively homogeneous in healthcare characteristics or needs is crucial to facilitate integrated care and resource planning. We aimed to evaluate the feasibility of segmenting the population into discrete, non-overlapping groups using a practical expert and literature driven approach. We hypothesized that this approach is feasible utilizing the electronic health record (EHR) in SingHealth. METHODS: In addition to well-defined segments of "Mostly healthy", "Serious acute illness but curable" and "End of life" segments that are also present in the Ministry of Health Singapore framework, patients with chronic diseases were segmented into "Stable chronic disease", "Complex chronic diseases without frequent hospital admissions", and "Complex chronic diseases with frequent hospital admissions". Using the electronic health record (EHR), we applied this framework to all adult patients who had a healthcare encounter in the Singapore Health Services Regional Health System in 2012. ICD-9, 10 and polyclinic codes were used to define chronic diseases with a comprehensive look-back period of 5 years. Outcomes (hospital admissions, emergency attendances, specialist outpatient clinic attendances and mortality) were analyzed for years 2012 to 2015. RESULTS: Eight hundred twenty five thousand eight hundred seventy four patients were included in this study with the majority being healthy without chronic diseases. The most common chronic disease was hypertension. Patients with "complex chronic disease" with frequent hospital admissions segment represented 0.6% of the eligible population, but accounted for the highest hospital admissions (4.33 +/- 2.12 admissions; p < 0.001) and emergency attendances (ED) (3.21 +/- 3.16 ED visits; p < 0.001) per patient, and a high mortality rate (16%). Patients with metastatic disease accounted for the highest specialist outpatient clinic attendances (27.48 +/- 23.68 visits; p < 0.001) per patient despite their relatively shorter course of illness and high one-year mortality rate (33%). CONCLUSION: This practical segmentation framework can potentially distinguish among groups of patients, and highlighted the high disease burden of patients with chronic diseases. Further research to validate this approach of population segmentation is needed. PMID- 29169360 TI - Positioning pharmacists' roles in primary health care: a discourse analysis of the compensation plan in Alberta, Canada. AB - BACKGROUND: A comprehensive Compensation Plan for pharmacy services delivered by community pharmacists was implemented in Alberta, Canada in July 2012. Services covered by the Compensation Plan include care planning services, prescribing services such as adapting prescriptions, and administering a drug or publicly funded vaccine by injection. Understanding how the Compensation Plan was framed and communicated provides insight into the roles of pharmacists and the potential influence of language on the implementation of services covered by the Compensation Plan by Albertan pharmacists. The objective of this study is to examine the positioning of pharmacists' roles in documents used to communicate the Compensation Plan to Albertan pharmacists and other audiences. METHODS: Publicly available documents related to the Compensation Plan, such as news releases or reports, published between January 2012 and December 2015 were obtained from websites such as the Government of Alberta, Alberta Blue Cross, the Alberta College of Pharmacists, the Alberta Pharmacists' Association, and the Blueprint for Pharmacy. Searches of the Canadian Newsstand database and Google identified additional documents. Discourse analysis was performed using social positioning theory to explore how pharmacists' roles were constructed in communications about the Compensation Plan. RESULTS: In total, 65 publicly available documents were included in the analysis. The Compensation Plan was put forward as a framework for payment for professional services and formal legitimization of pharmacists' changing professional roles. The discourse associated with the Compensation Plan positioned pharmacists' roles as: (1) expanding to include services such as medication management for chronic diseases, (2) contributing to primary health care by providing access to services such as prescription renewals and immunizations, and (3) collaborating with other health care team members. Pharmacists' changing roles were positioned in alignment with the aims of primary health care. CONCLUSIONS: Social positioning theory provides a useful lens to examine the dynamic and evolving roles of pharmacists. This study provides insight into how communications regarding the Compensation Plan in Alberta, Canada positioned pharmacists' changing roles in the broader context of changes to primary health care delivery. Our findings may be useful for other jurisdictions considering implementation of remunerated clinical services provided by pharmacists. PMID- 29169361 TI - Differentiation of human adipose-derived stem cells into cardiomyocyte-like cells in fibrin scaffold by a histone deacetylase inhibitor. AB - BACKGROUND: Human adipose-derived stem cells (hADSCs) are capable of differentiating into many cells such as cardiac cells. Different types of inducers are used for cardiac cell differentiation, but this question still remains to be investigated, which one is the best. The aim of this paper was to investigate the effect of combination of fibrin scaffold and trichostatin A (TSA), for differentiation of hADSCs into cardiomyocyte-like cells. METHODS: After approval of characteristics of hADSCs and fibrin scaffold, hADSCs were cultured in fibrin scaffold with 10 uM TSA for 72 h and kept in standard conditions for 4 weeks. QRT-PCR and immunostaining assay were performed for evaluating the expression pattern of special cardiac genes and proteins. RESULTS: In particular, our study showed that fibrin scaffold alongside TSA enhanced expression of the selected genes and proteins. CONCLUSIONS: We concluded that the TSA alone or with fibrin scaffold can lead to the generation of cardiac like cells in a short period of time. PMID- 29169362 TI - Influence of enhanced recovery after surgery programs on laparoscopy-assisted gastrectomy for gastric cancer: a systematic review and meta-analysis of randomized control trials. AB - BACKGROUND: This meta-analysis is aimed to evaluate the feasibility and safety of enhanced recovery after surgery (ERAS) programs in gastric cancer patients undergoing laparoscopy-assisted gastrectomy (LAG). METHODS: We performed a meta analysis of randomized control trials involving either enhanced recovery after surgery (ERAS)/fast track surgery (FTS) for patients underwent LAG. EMBASE, Pubmed, Web of science, and Cochrane Library were searched. Primary outcomes included the length of postoperative hospital stay, cost of hospitalization, postoperative complications, and readmission rate. RESULTS: Five randomized control trials were eligible for analysis. There were 159 cases in FTS group and 156 cases in conventional care group. Compared with conventional care group, FTS group relates to shorter postoperative hospital stay (WMD - 2.16; 95% CI - 3.05 to - 1.26, P < 0.00001), less cost of hospitalization (WMD - 4.72; 95% CI - 6.88 to - 2.55, P < 0.00001), shorter time to first flatus (WMD - 9.72; 95% CI - 13.75 to - 5.81, P < 0.00001), lower level of C-reaction protein on postoperative days 3 or 4 (WMD - 19.66; 95% CI - 28.98 to - 10.34, P < 0.00001), higher level of albumin on postoperative day 4 (WMD 3.45; 95% CI 2.01 to 4.89, P < 0.00001), and postoperative day 7 (WMD 5.63; 95% CI 1.01 to 10.24, P = 0.02). Regarding postoperative complications, no significant differences were observed between FTS group and conventional care group (OR 0.63, 95% CI 0.37 to 1.09, P = 0.10). The readmission rate of FTS group was comparable to conventional care group (WMD 3.14; 95% CI 0.12 to 81.35, P = 0.49). CONCLUSIONS: Among patients undergoing LAG, FTS is associated with shorter postoperative hospital stay, rapid postoperative recovery, and decreased cost without increasing complications or readmission rate. The combined effects of the two methods could further accelerate clinical recovery of gastric cancer patients. PMID- 29169363 TI - Impact of connective tissue disease on the surgical outcomes of aortic dissection in patients with cystic medial necrosis. AB - BACKGROUND: A retrospective analysis was performed to determine the impact of genetically diagnosed connective tissue disease (CTD) on the early and late outcomes of surgical treatment for aortic dissection in patients having aortic pathology associated with cystic medial necrosis (CMN). METHODS: Between 2003 and 2013, a total of 43 patients (37 +/- 12.8 years old, 23 men, 20 women) who had undergone surgery for aortic dissection associated with CMN in the aortic wall underwent genetic examinations. Subsequently, there were 30 patients with CTD (CTD group) and 13 without CTD (non-CTD group). RESULTS: There were no early or late deaths (the follow-up rate was 100% for 57.1 +/- 43.0 months). The median age was significantly lower in the CTD group (p = 0.030). The rate of elastic fiber loss was significantly higher in the CTD group (p = 0.014). In the long term follow-up, there were no significant differences in the incidences of re dissection (p = 0.332). However, re-operations were required more frequently in the CTD group (p = 0.037). CONCLUSIONS: In patients with CTD as well as CMN, the onset of aortic dissection tends to be earlier, which would result in higher rates of re-operation, compared with the non-CTD group. Closer and stricter follow-up with medication and adequate surgical treatments with appropriate timing are mandatory for such high-risk patients. PMID- 29169364 TI - Policymakers' experience of a capacity-building intervention designed to increase their use of research: a realist process evaluation. AB - BACKGROUND: An intervention's success depends on how participants interact with it in local settings. Process evaluation examines these interactions, indicating why an intervention was or was not effective, and how it (and similar interventions) can be improved for better contextual fit. This is particularly important for innovative trials like Supporting Policy In health with Research: an Intervention Trial (SPIRIT), where causal mechanisms are poorly understood. SPIRIT was testing a multi-component intervention designed to increase the capacity of health policymakers to use research. METHODS: Our mixed-methods process evaluation sought to explain variation in observed process effects across the six agencies that participated in SPIRIT. Data collection included observations of intervention workshops (n = 59), purposively sampled interviews (n = 76) and participant feedback forms (n = 553). Using a realist approach, data was coded for context-mechanism-process effect configurations (retroductive analysis) by two authors. RESULTS: Intervention workshops were very well received. There was greater variation of views regarding other aspects of SPIRIT such as data collection, communication and the intervention's overall value. We identified nine inter-related mechanisms that were crucial for engaging participants in these policy settings: (1) Accepting the premise (agreeing with the study's assumptions); (2) Self-determination (participative choice); (3) The Value Proposition (seeing potential gain); (4) 'Getting good stuff' (identifying useful ideas, resources or connections); (5) Self-efficacy (believing 'we can do this!'); (6) Respect (feeling that SPIRIT understands and values one's work); (7) Confidence (believing in the study's integrity and validity); (8) Persuasive leadership (authentic and compelling advocacy from leaders); and (9) Strategic insider facilitation (local translation and mediation). These findings were used to develop tentative explanatory propositions and to revise the programme theory. CONCLUSION: This paper describes how SPIRIT functioned in six policy agencies, including why strategies that worked well in one site were less effective in others. Findings indicate a complex interaction between participants' perception of the intervention, shifting contextual factors, and the form that the intervention took in each site. Our propositions provide transferable lessons about contextualised areas of strength and weakness that may be useful in the development and implementation of similar studies. PMID- 29169365 TI - Physician perspectives on the burden and management of asthma in six countries: The Global Asthma Physician Survey (GAPS). AB - BACKGROUND: Despite recognition of asthma as a growing global issue and development of global guidelines, asthma treatment practices vary between countries. Several studies have reported patients' perspectives on asthma control. This study presents physicians' perspectives and strategies for asthma management. METHODS: Physicians seeing >=4 adult patients with asthma per month in Australia, Canada, China, France, Germany, and Japan were surveyed (N=1809; ~300 per country). A standardised questionnaire was developed for this study and administered by telephone, online or face-to-face. Statistics were weighted to account for the sampling scheme. RESULTS: Physicians estimated that 71% of their adult patients received maintenance medication, with adherence monitored by 76 97% of physicians. Perceived major barriers to patient adherence included: patients taking treatment as needed; acceptance of symptoms; and patients not perceiving treatment benefits. Written action plans (37%) and technology (15%) were seldom employed by physicians to aid patients' asthma management. Physicians rarely (10%) used validated patient-reported questionnaires to monitor asthma control, instead monitoring selected symptoms, exacerbations, and/or lung function measurements. Awareness of single maintenance and reliever therapy (SMART/MART) varied among countries (56-100%); although most physicians (72%) had prescribed SMART/MART, the majority (91%) co-prescribed a short-acting bronchodilator at least some of the time. CONCLUSIONS: These results show that physicians generally do not employ standardised tools to monitor asthma control or to manage its treatment and that despite high awareness of SMART/MART, the strategy appears to be commonly misapplied. Better education for patients and physicians is required to improve asthma management and resulting patient outcomes. PMID- 29169366 TI - A case report of pulmonary tritrichomonosis in a pig. AB - BACKGROUND: Tritrichomonads like porcine Tritrichomonas foetus (previously named Tritrichomonas suis), can commensally live in nasal cavity of pigs, but it is rare to cause pulmonary tritrichomonosis. CASE PRESENTATION: A 40-day-old piglet was presented for persistent labor breathing and diagnosed with parasite infections in the lung by analysis of bronchoalveolar lavage (BAL) under microscope. By taking advantage of next-generation sequencing approach, we found 9611 homologous tags belonging to 50 annotated genes of tritrichomonads by analysis of mRNA of the bronchoalveolar lavage with the parasite infection. Furthermore, RT-PCR and DNA sequencing analysis confirmed the presence of the tritrichomonad. FINDINGS: Here, we report a case of pulmonary tritrichomonosis in a pig. By taking advantage of next-generation sequencing approach, we found 9611 homologous tags belonging to 50 annotated genes of tritrichomonads by analysis of mRNA of the bronchoalveolar lavage with the parasite infections. Furthermore, RT PCR and DNA sequencing analysis confirmed the presence of the tritrichomonad. CONCLUSION: Our results demonstrate that tritrichomonads like porcine Tritrichomonas foetus can cause lung infections of pigs and reveal that next generation sequencing is potential to identify rare diseases like pulmonary tritrichomonosis in clinical. PMID- 29169367 TI - Image-based quantitative analysis of tear film lipid layer thickness for meibomian gland evaluation. AB - BACKGROUND: Dry eye syndrome is one of the most common ocular diseases, and meibomian gland dysfunction (MGD) is the leading cause of evaporative dry eye syndrome. When the tear film lipid layer becomes thin due to obstructive or hyposecretory meibomian gland dysfunction, the excessive evaporation of the aqueous layer can occur, and this causes evaporative dry eye syndrome. Thus, measuring the lipid layer thickness (LLT) is essential for accurate diagnosis and proper treatment of evaporative dry eye syndrome. METHODS: We used a white LED panel with a slit lamp microscope to obtain videos of the lipid layer interference patterns on the cornea. To quantitatively analyze the LLT from interference colors, we developed a novel algorithm that can automatically perform the following processes on an image frame: determining the radius of the iris, locating the center of the pupil, defining region of interest (ROI), tracking the ROI, compensating for the color of iris and illumination, and producing comprehensive analysis output. A group of dry eye syndrome patients with hyposecretory MGD, dry eye syndrome without MGD, hypersecretory MGD, and healthy volunteers were recruited. Their LLTs were analyzed and statistical information-mean and standard deviation, the relative frequency of LLT at each time point, and graphical LLT visualization-were produced. RESULTS: Using our algorithm, we processed the lipid layer interference pattern and automatically analyzed the LLT distribution of images from patients. The LLT of hyposecretory MGD was thinner (45.2 +/- 11.6 nm) than that of dry eye syndrome without MGD (69.0 +/- 9.4 nm) and healthy volunteers (68.3 +/- 13.7 nm) while the LLT of hypersecretory MGD was thicker (93.5 +/- 12.6 nm) than that of dry eye syndrome without MGD. Patients' LLTs were statistically analyzed over time, visualized with 3D surface plots, and displayed using 3D scatter plots of image pixel data for comprehensive assessment. CONCLUSIONS: We developed an image-based algorithm for quantitative measurement as well as statistical analysis of the LLT despite fluctuation and eye movement. This pilot study demonstrates that the quantitative LLT analysis of patients is consistent with the functions of meibomian glands clinically evaluated by an ophthalmologist. This approach is a significant step forward in developing a fully automated instrument for evaluating dry eye syndrome and for providing proper guidance of treatment. PMID- 29169368 TI - Inactive lifestyles and sedentary behavior in persons with chronic aneurysmal subarachnoid hemorrhage: evidence from accelerometer-based activity monitoring. AB - BACKGROUND: Aneurysmal subarachnoid hemorrhage (a-SAH) is a potential life threatening stroke. Because survivors may be at increased risk for inactive and sedentary lifestyles, this study evaluates physical activity (PA) and sedentary behavior (SB) in the chronic phase after a-SAH. METHODS: PA and SB were objectively measured at six months post a-SAH with an accelerometer-based activity monitor, with the aim to cover three consecutive weekdays. Total time spent in PA (comprising walking, cycling, running and non-cyclic movement) and SB (comprising sitting and lying) was determined. Also, in-depth analyses were performed to determine the accumulation and distribution of PA and SB throughout the day. Binary time series were created to determine the mean bout length and the fragmentation index. Measures of PA and SB in persons with a-SAH were compared to those in sex- and age-matched healthy controls. RESULTS: The 51 participants comprised 33 persons with a-SAH and 18 controls. None of the participants had signs of paresis or spasticity. Persons with a-SAH spent 105 min/24 h being physically active, which was 35 min/24 h less than healthy controls (p = 0.005). For PA, compared with healthy controls, the mean bout length was shorter in those with a-SAH (12.0 vs. 13.5 s, p = 0.006) and the fragmentation index was higher (0.053 vs. 0.041, p < 0.001). Total sedentary time during waking hours showed no significant difference between groups (514 min vs. 474 min, p = 0.291). For SB, the mean bout length was longer in persons with a SAH (122.3 vs. 80.5 s, p = 0.024), whereas there was no difference in fragmentation index between groups (0.0032 vs 0.0036, p = 0.396). CONCLUSIONS: Persons with a-SAH are less physically active, they break PA time into shorter periods, and SB periods last longer compared to healthy controls. Since inactive lifestyles and prolonged uninterrupted periods of SB are independent risk factors for poor cardiovascular health, interventions seem necessary and should target both PA and SB. STUDY REGISTRATION: Dutch registry number: NTR 2085. PMID- 29169369 TI - In vivo screening and evaluation of four herbs against MRSA infections. AB - BACKGROUND: Recently, we reported high in vitro antibacterial efficacy of Althaea officinalis, Ziziphus jujuba, Cordia latifolia and Thymus vulgaris out of a total 21 plants against wide range of bacteria including MRSA. This study was therefore, designed to confirm efficacy of these four herbs against MRSA in an animal model. METHODS: A pilot study was conducted to establish the dose of S. aureus (KY698020) required to induce clinical infection. Afterword, in main trial, efficacy of aforementioned plant extracts on the course of sore throat was checked by evaluating general health, gross lesion score, bacterial load and hematology in mice. RESULTS: Pilot study revealed that 40 MUl dose of 107 CFU/ml could induce infection which persist upto 08 days post infection. Mice treated with T. vulgaris and Z. jujuba showed reduction in gross lesion score of both heart and lungs. Treatment with only some plants could significantly decrease bacterial load of throat (T. vulgaris) heart, blood and joint (C. latifolia, and T. vulagris). Hematological indicators confirmed in vivo control of MRSA infection in all treatment groups except A. officinalis. CONCLUSION: This is first report confirming in vivo anti-MRSA potential of C. latifolia and T. vulgaris and highlight the need to explore bioactive constituents of these plants. Moreover, previously reported in vitro antibacterial efficiency of A. officinalis could not be validated in current study. PMID- 29169370 TI - Cisplatin triggers cancer stem cell enrichment in platinum-resistant cells through NF-kappaB-TNFalpha-PIK3CA loop. AB - BACKGROUND: Parallel to complex alteration in molecular and cellular events, enrichment of cancer stem cells (CSC) contributes significantly in deliberation and maintenance of cisplatin resistance. Cisplatin mediated CSC enrichment is well established in various cancers, yet the underlying mechanism is largely unknown. Cisplatin also promotes transcriptional upregulation of PIK3CA, hence activating PI3K/AKT signaling in resistant cells. However, such cisplatin-induced transcriptional regulators of PIK3CA and their impact on cancer stem cell population in resistant cells are largely unknown. METHODS: DNA-binding protein pulldown using PIK3CA promoter as bait followed by nLCMS was used to identify, cisplatin-induced potential transcriptional regulators of PIK3CA promoter. PIK3CA promoter activity was estimated by luciferase based reporter assay. ChIP was used to assess interaction of NF-kappaB with PIK3CA promoter. CSC-enriched side population was sorted using DCV-dye exclusion methods. All the gene expression levels were assessed using qPCR. RESULTS: Using a transcription factor pull-down assay with PIK3CA promoter, we identified NF-kappaB as a prime regulator, which escalates both TNFalpha and PIK3CA expression only in CSC enriched side population (SP) but not in non side-population (NSP) in platinum resistant ovarian cancer cells upon cisplatin treatment. This SP-specific NF-kappaB TNFalpha-PIK3CA bi-modal loop, on one hand, maintains persistent activation of NF kappaB through TNFalpha- NF-kappaB autocrine loop, while NF-kappaB-PIK3CA loop nurture CSC population under cisplatin treatment. Activation of PI3K/AKT signalling drives SP's into an undifferentiated, anti-apoptotic stage through upregulating P21, P27,cFLIP expression. Contrarily, lack of active NF-kappaB TNFalpha-PIK3CA loop makes NSPs vulnerable towards cisplatin and undergoes apoptosis. Altogether, cisplatin enriches cancer stem cells properties in SP fraction, which is evident from increased levels of pluripotency gene OCT4/SOX2/NANOG expression. Disruption of PIK3CA-NF-kappaB loop by Wortamannin reduces SP fraction by 1.4-1.6 fold in control and treated cells. CONCLUSION: Together, our study signifies an active role of NF-kappaB-TNFalpha-PIK3CA bi modal loop in cisplatin-mediated promotion and maintenance of CSC-like population in platinum-resistant cells.

PMID- 29169372 TI - Association between diet and gallstones of cholesterol and pigment among patients with cholecystectomy: a case-control study in Korea. AB - BACKGROUND: The prevalence of cholesterol gallstones is high in Western populations, while pigment gallstones are common in Asian populations. Dietary factors are suggested to be associated with gallstone risk, but their relationship with gallstone type has not been evaluated. This study investigated the association between diet and risk of cholesterol gallstone or pigment gallstone in a Korean population whose dietary pattern and type of gallstone were changed during the last 30 years. METHODS: Patients with cholesterol (n = 40) and pigment (n = 59) gallstones were recruited after laparoscopic cholecystectomy and were compared with those of age- and sex-matched controls without gallstones (n = 99). Dietary intakes were assessed by trained dietitians using a semi quantitative food frequency questionnaire. Multinomial logistic regression analysis was performed to calculate odds ratios and 95% confidence intervals to examine the associations between diet and risk for type of gallstones adjusted by potential confounders. RESULTS: Patients with cholesterol gallstone consumed more lipid, animal lipid, beef, pork, and fried food than those with pigment gallstones and control, while patients with pigment gallstone consumed more carbohydrate and noodles than patients with cholesterol gallstone and control. In multinomial logistic regression analysis using control as reference group, dietary pattern with high consumption of beef, pork, and fried food was associated with risk of cholesterol gallstones, while there was no association between the risk of pigment gallstone and dietary pattern. In addition, control consumed more alcohol than patients with cholesterol and pigment gallstones. CONCLUSIONS: The present study suggested consumption of fat from meat and fried foods increased the risk of cholesterol gallstone, and intake of carbohydrate from noodles increased the risk of pigment gallstone. PMID- 29169373 TI - The Treatment In Morning versus Evening (TIME) study: analysis of recruitment, follow-up and retention rates post-recruitment. AB - BACKGROUND: The use of information technology (IT) is now the preferred method of capturing and storing clinical research data. The Treatment In Morning versus Evening (TIME) study predominantly uses electronic data capture and IT to compare morning dosing of hypertensive medication against evening dosing. Registration, consent, participant demographics and follow-up data are all captured via the study website. The aim of this article is to assess the success of the TIME methodology compared with similar studies. METHODS: To assess the TIME study, published literature on similar clinical trials was reviewed and compared against TIME recruitment, follow-up and email interaction data. RESULTS: The TIME website registered 31,695 individuals, 21,116 of whom were randomised. Recruitment cost per randomised participant varied by strategy: L17.40 by GP practice, L3.08 by UK Biobank and L58.82 for GoShare. Twelve-month follow-up retention rates were 96%. A total of 1089 participants have withdrawn from their assigned time of dosing, 2% of whom have declined follow-up by record linkage or further contact. When the TIME data are compared with similar study data, study recruitment is very successful. However, TIME suffers difficulties with participant follow-up and withdrawal rates similar to those of conventional studies. CONCLUSIONS: The TIME study has been successful in recruitment. Follow-up, retention rates and withdrawal rates are all acceptable, but ongoing work is required to ensure participants remain engaged with the study. Various recruitment strategies are necessary, and all viable options should be encouraged to maintain participant engagement throughout the life of studies using IT. PMID- 29169374 TI - ID1 promotes hepatocellular carcinoma proliferation and confers chemoresistance to oxaliplatin by activating pentose phosphate pathway. AB - BACKGROUND: Drug resistance is one of the major concerns in the treatment of hepatocellular carcinoma (HCC). The aim of the present study was to determine whether aberrant high expression of the inhibitor of differentiation 1(ID1) confers oxaliplatin-resistance to HCC by activating the pentose phosphate pathway (PPP). METHODS: Aberrant high expression of ID1 was detected in two oxaliplatin resistant cell lines MHCC97H-OXA(97H-OXA) and Hep3B-OXA(3B-OXA). The lentiviral shRNA or control shRNA was introduced into the two oxaliplatin-resistant cell lines. The effects of ID1 on cell proliferation, apoptosis and chemoresistance were evaluated in vitro and vivo. The molecular signaling mechanism underlying the induction of HCC proliferation and oxaliplatin resistance by ID1 was explored. The prognostic value of ID1/G6PD signaling in HCC patients was assessed using the Cancer Genome Atlas (TCGA) database. RESULTS: ID1 was upregulated in oxaliplaitin-resistant HCC cells and promoted HCC cell proliferation and oxaliplatin resistance. Silencing ID1 expression in oxaliplaitin-resistant HCC cell lines inhibited cell proliferation and sensitized oxaliplaitin-resistant cells to death. ID1 knockdown significantly decreased the expression of glucose-6 phosphate dehydrogenase (G6PD), a key enzyme of the PPP. Silencing ID1 expression blocked the activation of G6PD, decreased the production of PPP NADPH, and augmented reactive oxygen and species (ROS), thus inducing cell apoptosis. Study of the molecular mechanism showed that ID1 induced G6PD promoter transcription and activated PPP through Wnt/beta-catenin/c-MYC signaling. In addition, ID1/G6PD signaling predicted unfavorable prognosis of HCC patients on the basis of TCGA. CONCLUSIONS: Our study provided the first evidence that ID1 conferred oxaliplatin resistance in HCC by activating the PPP. This newly defined pathway may have important implications in the research and development of new more effective anti cancer drugs. PMID- 29169376 TI - The mediating factors in the relationship between lower urinary tract symptoms and health-related quality of life. AB - OBJECTIVES: An earlier study found that mental health partially mediates the relationship between lower urinary tract symptoms (LUTS) severity and health related quality of life (HRQOL). In other words, LUTS adversely affects mental health, which in turn adversely affects HRQOL. A major limitation of the previous study was its cross-sectional design. The aim of this study is to evaluate whether changes in mental health mediated the association between changes in the severity of LUTS and changes in HRQOL over 24 months by using Baron and Kenny's regression procedure and Preacher and Hayes's bootstrapping method. RESULTS: We found that changes in mental health were a mediator in the relationship between the change of LUTS severity and the change of LUTS-specific HRQOL. Changes in LUTS severity lead to changes in mental health, which in turn affects the change of LUTS-specific HRQOL. It was observed however that changes in mental health did not mediate the relationship between the change of LUTS severity and the change of the physical aspects of generic HRQOL. These findings suggest that in order to optimize LUTS-specific HRQOL, both LUTS severity and mental health may need to be addressed concurrently. PMID- 29169375 TI - Synaptic configuration of quadrivalents and their association with the XY bivalent in spermatocytes of Robertsonian heterozygotes of Mus domesticus. AB - BACKGROUND: The nuclear architecture of meiotic prophase spermatocytes is based on higher-order patterns of spatial associations among chromosomal domains and consequently is prone to modification by chromosomal rearrangements. We have shown that nuclear architecture is modified in spermatocytes of Robertsonian (Rb) homozygotes of Mus domesticus. In this study we analyse the synaptic configuration of the quadrivalents formed in the meiotic prophase of spermatocytes of mice double heterozygotes for the dependent Rb chromosomes: Rbs 11.16 and 16.17. RESULTS: Electron microscope spreads of 60 pachytene spermatocytes from four animals of Mus domesticus 2n = 38 were studied and their respective quadrivalents analysed in detail. Normal synaptonemal complex was found between arms 16 of the Rb metacentric chromosomes, telocentrics 11 and 17 and homologous arms of the Rb metacentric chromosomes. About 43% of the quadrivalents formed a synaptonemal complex between the heterologous short arms of chromosomes 11 and 17. This synaptonemal complex is bound to the nuclear envelope through a fourth synapsed telomere, thus dragging the entire quadrivalent to the nuclear envelope. About 57% of quadrivalents showed unsynapsed single axes in the short arms of the telocentric chromosomes. About 90% of these unsynapsed quadrivalents also showed a telomere-to-telomere association between one of the single axes of the telocentric chromosome 11 or 17 and the X chromosome single axis, which was otherwise normally paired with the Y chromosome. Nucleolar material was associated with two bivalents and with the quadrivalent. CONCLUSIONS: The spermatocytes of heterozygotes for dependent Rb chromosomes formed a quadrivalent where four chromosomes are synapsed together and bound to the nuclear envelope through four telomeres. The nuclear configuration is determined by the fourth shortest telomere, which drags the centromere regions and heterochromatin of all the chromosomes towards the nuclear envelope, favouring the reiterated encounter and eventual rearrangement between the heterologous chromosomes. The unsynapsed regions of quadrivalents are frequently bound to the single axis of the X chromosome, possibly perturbing chromatin condensation and gene expression. PMID- 29169377 TI - First detection of Wolbachia-infected Culicoides (Diptera: Ceratopogonidae) in Europe: Wolbachia and Cardinium infection across Culicoides communities revealed in Spain. AB - BACKGROUND: Biting midges of the genus Culicoides (Diptera: Ceratopogonidae) transmit pathogens that cause important diseases. No effective technique has been found to properly control either Culicoides spp. abundance or their likelihood to transmit pathogens. Endosymbionts, particularly Wolbachia, represent powerful alternatives to control arthropods of health interest. In arthropods, Wolbachia can reduce vector fitness and vector's pathogen transmission capacity, thus being a potential target for population reduction and replacement strategies. RESULTS: The presence of Wolbachia and Cardinium endosymbionts was screened in Spanish Culicoides spp. populations at livestock premises and natural habitats. The first detection of Wolbachia-infected Culicoides spp. in Europe is reported. The putative Palaearctic vectors for bluetongue and Schmallenberg diseases, C. imicola, C. obsoletus (s.s.) and C. pulicaris (s.l.), were infected with Wolbachia. Four genetic clusters of closely-related Wolbachia strains from A and B supergroups were detected infecting Culicoides. Cardinium strain of the C-group was detected in C. obsoletus (s.l.). Both endosymbionts, Wolbachia and Cardinium, were detected in Culicoides species of minor epidemiological relevance as well. Higher prevalence of Wolbachia infection was detected in natural habitats, while livestock premises lead to higher prevalence of Cardinium. Significant differences in the prevalence of Wolbachia, but not Cardinium, were also detected between some Culicoides species and between locations. CONCLUSIONS: The presence of Wolbachia and Cardinium endosymbionts in Culicoides is expected to trigger new research towards the control of Culicoides-transmitted diseases. The results of the present study could have an impact beyond the Culicoides arena because successful Wolbachia transfection is possible even across genus and species barriers. PMID- 29169378 TI - Network methods to support user involvement in qualitative data analyses: an introduction to Participatory Theme Elicitation. AB - BACKGROUND: While Patient and Public Involvement (PPI) is encouraged throughout the research process, engagement is typically limited to intervention design and post-analysis stages. There are few approaches to participatory data analyses within complex health interventions. METHODS: Using qualitative data from a feasibility randomised controlled trial (RCT), this proof-of-concept study tests the value of a new approach to participatory data analysis called Participatory Theme Elicitation (PTE). Forty excerpts were given to eight members of a youth advisory PPI panel to sort into piles based on their perception of related thematic content. Using algorithms to detect communities in networks, excerpts were then assigned to a thematic cluster that combined the panel members' perspectives. Network analysis techniques were also used to identify key excerpts in each grouping that were then further explored qualitatively. RESULTS: While PTE analysis was, for the most part, consistent with the researcher-led analysis, young people also identified new emerging thematic content. CONCLUSIONS: PTE appears promising for encouraging user led identification of themes arising from qualitative data collected during complex interventions. Further work is required to validate and extend this method. TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT02455986 . Retrospectively Registered on 21 May 2015. PMID- 29169379 TI - Exponential distribution of total depressive symptom scores in relation to exponential latent trait and item threshold distributions: a simulation study. AB - OBJECTIVES: Total depressive symptom scores in the general population have been reported to follow an exponential distribution except at the lowest end of the range of scores. To verify the hypothesis that total depressive symptom scores follow the distribution of the latent trait, we performed a simulation study of depressive symptom scoring modeled after the Revised Clinical Interview Schedule (CIS-R). To simulate the scoring of ordinal scale items in CIS-R, two sets of random numbers were generated, one expressing the degree of the latent trait of depressive symptoms and another expressing the threshold for each item. Random latent trait numbers greater than those of item thresholds indicated the presence of specific symptoms. RESULTS: When exponential distribution was set to the latent trait's random numbers and each item's threshold had a certain degree of standard deviation, simulated total depressive symptom scores showed a linear pattern except at the lowest end of scores with a log-normal scale. Our results suggest that total depressive symptom scores follow the distribution of the latent trait of depressive symptoms due to the property of ordinal scales, which is characterized by individual differences in the threshold of each item.

PMID- 29169381 TI - Surgical resection of advanced non-small cell lung cancer after a response to EGFR-TKI: presentation of two cases and a literature review. AB - BACKGROUND: The usefulness of residual tumor resection after epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) treatment remains unclear. We describe two patients who underwent residual tumor resection after responding to EGFR-TKIs for advanced non-small cell lung cancer (NSCLC) harboring EGFR gene mutations, along with a review of the literature. CASE PRESENTATION: The patient in Case 1 was a 72-year-old female non-smoker who was initially diagnosed with T2aN2M0, stage IIIA adenocarcinoma harboring an EGFR exon 21 L858R mutation. After 8 months of gefitinib therapy, a marked radiologic response was noted, and right upper lobectomy with systemic lymph node dissection was performed. The patient developed brain metastasis despite continuous gefitinib therapy. The patient in Case 2 was a 68-year-old female non-smoker who was initially diagnosed with T3N2M0, stage IIIA adenocarcinoma and an extensive pulmonary thromboembolism. After 3 months of therapy with afatinib and anticoagulants, a marked radiologic response and symptom relief were achieved. We then performed right bilobectomy with systemic lymph node dissection. She developed bone metastasis despite postoperative afatinib therapy. CONCLUSION: The timing and validity of salvage surgery for residual lesions remain unclear when TKIs are offered as first-line therapy to patients with advanced NSCLC. In our two cases, surgery was performed without any complications. Surgical resection of the residual tumor might contribute to good local control. The accumulation of more clinical data is needed to further investigate the role of surgery in patients with advanced NSCLC harboring EGFR gene mutations. PMID- 29169382 TI - Confirmed Ceylon krait (Bungarus ceylonicus) envenoming in Sri Lanka resulting in neuromuscular paralysis: a case report. AB - BACKGROUND: Ceylon krait (Bungarus ceylonicus) is a venomous elapid snake endemic to Sri Lanka. It inhabits shaded home gardens and forests in the wet zone of Sri Lanka and might creep into houses in the night. Despite frequent encounters with humans, reports of envenoming are very rare. CASE PRESENTATION: We report a case of a 26-year-old Sri Lankan Sinhalese man with confirmed Ceylon krait envenoming presenting with bilateral partial ptosis, ophthalmoplegia, facial muscle weakness, and dysphagia. Single fiber electromyography and repetitive nerve stimulation confirmed neuromuscular paralysis. He was administered polyvalent anti-venom serum immediately following admission without a prompt clinical response. Complete recovery was observed 3 days following the bite. CONCLUSIONS: Because of the rarity of envenoming, precise and detailed information on the clinical manifestations following envenoming is lacking. However, Ceylon krait bite can be potentially fatal; so, treating physicians should be aware of species identification, habitat, and biting habits and clinical presentation of envenoming of Ceylon krait. This case report adds knowledge to the existing limited literature available on Ceylon krait envenoming; a rare but potentially fatal clinical entity. PMID- 29169383 TI - Predictors of a follicular nodule (Thy3) outcome of thyroid fine needle aspiration cytology among Saudi patients. AB - OBJECTIVE: A retrospective study was performed to evaluate predictors of thyroid fine needle aspiration cytology (FNAC) outcomes among Saudis with a thyroid nodule. Socio-demographic data, thyroid function status, thyroid parameters, ultrasound and cytology results were collected from 269 files of patients with thyroid nodules. RESULT: The patients' age was 40 +/- 1.4 years (mean +/- SD), and the mean body mass index (BMI) was 30.3 +/- 1.2 kg/m2. The thyroid statuses were euthyroid (85.5%), hypothyroidism (7.4%) and hyperthyroidism (7.1%). Young age, an absence of irradiation history, and multinodular goitre were protective against Thy3 [(OR = 0.05, CI = 003-0.6, P = 0.024), (OR = 0.4, CI = 0.2-0.8, P = 0.012) and (OR = 2.5, CI = 1.2-5.3, P = 0.016), respectively]; a lower FT3 was protective against Thy4 (OR = 0.4, CI = 0.2-0.99, P = 0.046), the absence of cervical lymphadenopathy was associated with Thy2 (OR = 2.7, CI = 1.4-5, P = 0.001), and a solid nodule was associated with Thy2 and Thy3 [(OR = 1.2, CI = 0.3 0.97, P = 0.040) and (OR = 2.2, CI = 1-4.8, P = 0.039), respectively]. In a multivariate analysis, younger age, multinodular goitre, an absence of irradiation history and cervical lymphadenopathy were protective against Thy3 [(OR = 0.04, 95% CI = 0.002-0.96, P = 0.047), (OR = 2.4, 95% CI = 1.0-5.60, P = 0.039), (OR = 0.4, 95% CI = 0.16-0.94, P = 0.036) and (O R = 0.39, 95% CI = 1 5.6, P = 0.039), respectively]. In summary, younger age, multinodular goitre, the absence of an irradiation history and cervical lymphadenopathy were protective against Thy3 in a thyroid nodule. PMID- 29169384 TI - Assessing S. mansoni prevalence in Biomphalaria snails in the Gombe ecosystem of western Tanzania: the importance of DNA sequence data for clarifying species identification. AB - BACKGROUND: Snails are essential for the transmission and maintenance of schistosomiasis in endemic areas, as they serve as intermediate hosts for schistosome parasites. A clear understanding of the snail species present, their local distribution and infection status is therefore a prerequisite for effective control of schistosomiasis. The purpose of this study was to establish the infection status and distribution of Schistosoma mansoni in snails in the Gombe area along the shores of Lake Tanganyika in western Tanzania, using both detection of cercarial shedding and molecular approaches. METHODS: Snails were collected from streams located close to human settlements in Gombe National Park, as well as from nearby villages (Kiziba, Mtanga, Mwamgongo and Bugamba) and the largest town in the region (Kigoma). Snails were individually exposed to light to induce shedding of schistosome larvae, which were examined using a compound light microscope. Additionally, the internal transcribed spacer (ITS) region of the ribosomal RNA gene cluster was simultaneously amplified in both snails and their trematodes using a single polymerase chain reaction (PCR) and sequenced to confirm species identification. RESULTS: Snails morphologically identified as Biomphalaria pfeifferi were present in all streams except at Mtanga but their distribution was patchy in both time and space. Sequencing of PCR products indicated that not all snails were B. pfeifferi. None of the snails from Gombe or Bugamba shed schistosome larvae, while larvae were shed at all other sites. Overall, an infection prevalence of only 12% was observed in snails based on cercarial shedding. While 47% of the snails were PCR-positive for the 500 bp ITS fragment, which was predicted to indicate infection with S. mansoni, sequence data demonstrated that these bands are not species-specific and can be amplified from other trematode infections. In addition, a 1000 bp band was amplified in 14% of samples, which was identified as a trematode in the family Derogenidae. CONCLUSIONS: The results support the previous assumption that B. pfeifferi snails may be involved in transmitting schistosomiasis in the area but suggest that the community structure of both snails and trematodes may be more complicated than previously thought. This emphasises the importance of confirming species identifications using sequencing, rather than relying only on PCR-based diagnostics or cercarial shedding. PMID- 29169385 TI - Standardised Outcomes in Nephrology-Polycystic Kidney Disease (SONG-PKD): study protocol for establishing a core outcome set in polycystic kidney disease. AB - BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is the most common potentially life threatening inherited kidney disease and is responsible for 5-10% of cases of end-stage kidney disease (ESKD). Cystic kidneys may enlarge up to 20 times the weight of a normal kidney due to the growth of renal cysts, and patients with ADPKD have an increased risk of morbidity, premature mortality, and other life-time complications including renal and hepatic cyst and urinary tract infection, intracranial aneurysm, diverticulosis, and kidney pain which impair quality of life. Despite some therapeutic advances and the growing number of clinical trials in ADPKD, the outcomes that are relevant to patients and clinicians, such as symptoms and quality of life, are infrequently and inconsistently reported. This potentially limits the contribution of trials to inform evidence-based decision-making. The Standardised Outcomes in Nephrology Polycystic Kidney Disease (SONG-PKD) project aims to establish a consensus-based set of core outcomes for trials in PKD (with an initial focus on ADPKD but inclusive of all stages) that patients and health professionals identify as critically important. METHODS: The five phases of SONG-PKD are: a systematic review to identify outcomes that have been reported in existing PKD trials; focus groups with nominal group technique with patients and caregivers to identify, rank, and describe reasons for their choices; qualitative stakeholder interviews with health professionals to elicit individual values and perspectives on outcomes for trials involving patients with PKD; an international three-round Delphi survey with all stakeholder groups (including patients, caregivers, healthcare providers, policy makers, researchers, and industry) to gain consensus on critically important core outcome domains; and a consensus workshop to review and establish a set of core outcome domains and measures for trials in PKD. DISCUSSION: The SONG-PKD core outcome set is aimed at improving the consistency and completeness of outcome reporting across ADPKD trials, leading to improvements in the reliability and relevance of trial-based evidence to inform decisions about treatment and ultimately improve the care and outcomes for people with ADPKD. PMID- 29169386 TI - Spatiotemporal distribution and population at risk of soil-transmitted helminth infections following an eight-year school-based deworming programme in Burundi, 2007-2014. AB - BACKGROUND: Investigating the effect of successive annual deworming rounds on the spatiotemporal distribution of infection prevalence and numbers at risk for soil transmitted helminths (STHs) can help identify communities nearing elimination and those needing further interventions. In this study, we aim to quantify the impact of an 8-year mass drug administration (MDA) programme (from 2007 to 2014) on the spatiotemporal distribution of prevalence of STH infections and to estimate the number of school-aged children infected with STHs in Burundi. METHODS: During annual longitudinal school-based surveys in Burundi between 2007 and 2011, STH infection and anthropometric data for a total of 40,656 children were collected; these data were supplemented with data from a national survey conducted in 2014. Bayesian model based geostatistics (MBG) were used to generate predictive prevalence maps for each STH species and year. The numbers of children at-risk of infection per district between 2008 and 2014 were estimated as the product of the predictive prevalence maps and population density maps. RESULTS: Overall, the degree of spatial clustering of STH infections decreased between 2008 and 2011; in 2014 the geographical clusters of all STH infections reappeared. The reduction in prevalence was small for Ascaris lumbricoides and Trichuris trichiura in the centre and central north of the country. Our predictive prevalence maps for hookworm indicate a reduction in prevalence along the periphery of the country. The predicted number of children infected with any STH species decreased substantially between 2007 and 2011, but in 2014 there was an increase in the predicted number of children infected with A. lumbricoides and T. trichiura. In 2014, the districts with the highest predicted number of children infected with A. lumbricoides, T. trichiura and hookworms were Kibuye district (n = 128,903), Mabayi district (n = 35,302) and Kiremba (n = 87,511), respectively. CONCLUSIONS: While the MDA programme in Burundi resulted in a reduction in STH prevalence, this reduction was spatiotemporally heterogeneous, with some pockets of high prevalence remaining, suggesting that treatment coverage and complementary interventions should be evaluated to improve impact. PMID- 29169387 TI - Flotation techniques (FLOTAC and mini-FLOTAC) for detecting gastrointestinal parasites in howler monkeys. AB - BACKGROUND: Analyses of environmental correlates of the composition of gastrointestinal parasite communities in black howler monkeys (Alouatta pigra) have been hindered by inadequate calibration techniques of detection and quantification methods of the parasites. Here we calibrate samples and compare the likelihood of parasite detection using two flotation techniques, FLOTAC and Mini-FLOTAC, and compare flotation solution, preservation method and dilution ratio for egg detection and counts of the most common parasites (Controrchis spp. and Trypanoxyuris spp.) in howler monkeys. RESULTS: For samples preserved in 5% formalin, the Mini-FLOTAC technique was the best option for qualitative and quantitative copro-microscopic analysis. This technique displays an 83.3% and 100% detection of Controrchis spp. and Trypanoxyuris spp. infections, respectively. For the trematode Controrchis spp., more eggs per gram of feces (EPG) were recorded with the flotation solution (FS) #7 (zinc sulfate; specific gravity SG = 1.35) at 1:20 and 1:25 dilution than other methods. By contrast, for the nematode Trypanoxyuris spp., the best results were recorded with FS1 (sucrose and formaldehyde; SG = 1.20) at 1:10 dilution. CONCLUSIONS: We recommend the Mini FLOTAC technique for general use with parasite analysis on frugivore/folivores like the howler monkey, especially if many samples are analyzed. The technique has a high detection rate and the best EPG counts, allowing the qualitative and quantitative analysis of parasite load among the species or populations without the need for specialized equipment. PMID- 29169389 TI - Residential particulate matter and distance to roadways in relation to mammographic density: results from the Nurses' Health Studies. AB - BACKGROUND: High mammographic density is a strong, well-established breast cancer risk factor. Three studies conducted in various smaller geographic settings reported inconsistent findings between air pollution and mammographic density. We assessed whether particulate matter (PM) exposures (PM2.5, PM2.5-10, and PM10) and distance to roadways were associated with mammographic density among women residing across the United States. METHODS: The Nurses' Health Studies are prospective cohorts for whom a subset has screening mammograms from the 1990s (interquartile range 1990-1999). PM was estimated using spatio-temporal models linked to residential addresses. Among 3258 women (average age at mammogram 52.7 years), we performed multivariable linear regression to assess associations between square-root-transformed mammographic density and PM within 1 and 3 years before the mammogram. For linear regression estimates of PM in relation to untransformed mammographic density outcomes, bootstrapped robust standard errors are used to calculate 95% confidence intervals (CIs). Analyses were stratified by menopausal status and region of residence. RESULTS: Recent PM and distance to roadways were not associated with mammographic density in premenopausal women (PM2.5 within 3 years before mammogram beta = 0.05, 95% CI -0.16, 0.27; PM2.5-10 beta = 0, 95%, CI -0.15, 0.16; PM10 beta = 0.02, 95% CI -0.10, 0.13) and postmenopausal women (PM2.5 within 3 years before mammogram beta = -0.05, 95% CI 0.27, 0.17; PM2.5-10 beta = -0.01, 95% CI -0.16, 0.14; PM10 beta = -0.02, 95% CI 0.13, 0.09). Largely null associations were observed within regions. Suggestive associations were observed among postmenopausal women in the Northeast (n = 745), where a 10-MUg/m3 increase in PM2.5 within 3 years before the mammogram was associated with 3.4 percentage points higher percent mammographic density (95% CI -0.5, 7.3). CONCLUSIONS: These findings do not support that recent PM or roadway exposures influence mammographic density. Although PM was largely not associated with mammographic density, we cannot rule out the role of PM during earlier exposure time windows and possible associations among northeastern postmenopausal women. PMID- 29169388 TI - Vitamin D deficiency in critically ill children: a systematic review and meta analysis. AB - BACKGROUND: Vitamin D deficiency (VDD) has been hypothesized not only to be common but also to represent a potentially modifiable risk factor for greater illness severity and clinical outcome during critical illness. The objective of this systematic review was to determine the frequency of VDD in pediatric critical illness and its association with clinical outcomes. METHODS: MEDLINE, Embase, and CENTRAL were searched through December 12, 2016, with no date or language restrictions. The primary objective was to estimate the prevalence of VDD in the pediatric intensive care unit (PICU) and compare vitamin D status with healthy control populations. Secondary objectives were to evaluate whether VDD is associated with mortality, increased illness severity, PICU interventions, and patient clinical course. Random effects meta-analysis was used to calculate pooled VDD event rate, compare levels with those of control subjects, and evaluate for associations between VDD and clinical outcome. RESULTS: Among 2700 citations, 17 studies meeting study eligibility were identified. The studies reported a total of 2783 critically ill children and had a median sample size of 120 (range 12-511). The majority of studies used a 25-hydroxyvitamin D [25(OH)D] level less than 50 nmol/L to define VDD, and the pooled VDD prevalence was 54.8 (95% CI 45.4-63.9). Average 25(OH)D levels were significantly lower in PICU patients than in healthy control subjects (pooled difference -17.3 nmol/L, 95% CI -14.0 to -20.6). In a meta-analysis calculation, we found that VDD was associated with increased mortality (OR 1.62, 95% CI 1.11-2.36), illness severity, and need for PICU interventions. CONCLUSIONS: Approximately 50% of critically ill children have VDD at the time of PICU admission, defined as a blood total 25(OH)D concentration under 50 nmol/L. VDD was further determined to be associated with greater illness severity, multiple organ dysfunction, and mortality in the PICU setting. Clinical trials are required to determine if optimization of vitamin D status improves patient outcome. TRIAL REGISTRATION: PROSPERO, CRD42016026617 . Registered on 11 January 2016. PMID- 29169390 TI - Genomic analysis of bluetongue virus episystems in Australia and Indonesia. AB - The distribution of bluetongue viruses (BTV) in Australia is represented by two distinct and interconnected epidemiological systems (episystems)-one distributed primarily in the north and one in the east. The northern episystem is characterised by substantially greater antigenic diversity than the eastern episystem; yet the forces that act to limit the diversity present in the east remain unclear. Previous work has indicated that the northern episystem is linked to that of island South East Asia and Melanesia, and that BTV present in Indonesia, Papua New Guinea and East Timor, may act as source populations for new serotypes and genotypes of BTV to enter Australia's north. In this study, the genomes of 49 bluetongue viruses from the eastern episystem and 13 from Indonesia were sequenced and analysed along with 27 previously published genome sequences from the northern Australian episystem. The results of this analysis confirm that the Australian BTV population has its origins in the South East Asian/Melanesian episystem, and that incursions into northern Australia occur with some regularity. In addition, the presence of limited genetic diversity in the eastern episystem relative to that found in the north supports the presence of substantial, but not complete, barriers to gene flow between the northern and eastern Australian episystems. Genetic bottlenecks between each successive episystem are evident, and appear to be responsible for the reduction in BTV genetic diversity observed in the north to south-east direction. PMID- 29169391 TI - Factors associated with deaths in 'Elderly Housing with Care Services' in Japan: a cross-sectional study. AB - BACKGROUND: Although the Japanese government has expanded its 'Elderly Housing with Care Services' (EHCS) to ensure sufficient places of death for the elderly, resident deaths have occurred in less than 30% of the facilities. Our purpose was to identify the factors associated with residents' deaths in the EHCS, especially within the areas that are expected to have a large increase in the number of deaths. METHODS: Our cross-sectional study involved all EHCS (N = 412) in Japan's Tokyo, Kanagawa prefecture and used self-administered questionnaire data that the EHCS directors completed. In addition, we accessed the national statistics related to the municipal characteristics of the cities where the EHCS were located. These sources provided information about health care provision for the residents as well as facility/resident/regional characteristics that could potentially be associated with residents' deaths in the EHCS. Based on this information, a sequential multiple logistic regression analysis was performed. First, we included in-facility health care provision (presence of nursing staff) and facility/residents/regional characteristics in Model 1. Next, visiting nurse agency's care provision was included in Model 2. Finally, we included community hospitals or clinical care provision in Model 3. RESULTS: One hundred and fifty four facilities answered the questionnaire (response rate: 37.4%). A total of 114 facilities were analysed. In-facility residents' deaths occurred in more than half (54.4%) of the facilities. After adjusting for all variables (Model 3), end of-life (EOL) care provision from community hospitals or clinics, the number of years since establishment and the number of residents were significantly associated with residents' deaths. In Model 2, visiting nurse's EOL care provision was significantly associated with residents' death. CONCLUSION: Our results suggest that in order to accommodate residents' deaths, the government or the facility's directors should promote the cooperation between EHCS facilities and community hospitals or clinics for in-residents' EOL care. Furthermore, as the results suggest that community nurses contribute to the occurrences of death by collaborating with the physician, promoting cooperation with visiting nurse agencies may be also needed. PMID- 29169392 TI - Prognostic role of nodal ratio, LODDS, pN in patients with pancreatic cancer with venous involvement. AB - BACKGROUND: The UICC/AJCC TNM staging system classifies lymph nodes as N0 and N1 in pancreatic cancer. Aim of the study is to determine whether the number of examine nodes, the nodal ratio (NR) and the logarithm odds of positive lymph nodes (LODDS) may better stratify the prognosis of patients undergoing pancreatectomy combined with venous resection for pancreatic cancer with venous involvement. METHODS: A multicenter database of 303 patients undergoing pancreatectomy in 9 Italian referral centers was analyzed. The prognostic impact of number of retrieved and examined nodes, NR, LODDS was analyzed and compared with ROC curves analysis, Pearson test, univariate and multivariate analysis. RESULTS: The number of metastatic nodes, pN, the NR and LODDS was significantly correlated with survival at multivariate analyses. The corresponding AUC for the number of metastatic nodes, pN, the NR and LODDS were 0.66, 0.69, 0.63 and 0.65, respectively. The Pearson test showed a significant correlation between the number of retrieved lymph nodes and number of metastatic nodes, pN and the NR. LODDS had the lower coefficient correlation. Concerning N1 patients, the NR, the LODDS and the number of metastatic nodes were able to significantly further stratify survival (p = 0.040; p = 0.046; p = 0.038, respectively). CONCLUSIONS: The number of examined lymph nodes, the NR and LODDS are useful for further prognostic stratification of N1 patients in the setting of pancreatectomy combined with PV/SMV resection. No superiority of one over the others methods was detected. PMID- 29169393 TI - A systematic review and meta-analysis of online versus alternative methods for training licensed health care professionals to deliver clinical interventions. AB - BACKGROUND: Online training is growing in popularity and yet its effectiveness for training licensed health professionals (HCPs) in clinical interventions is not clear. We aimed to systematically review the literature on the effectiveness of online versus alternative training methods in clinical interventions for licensed Health Care Professionals (HCPs) on outcomes of knowledge acquisition, practical skills, clinical behaviour, self-efficacy and satisfaction. METHODS: Seven databases were searched for randomised controlled trials (RCTs) from January 2000 to June 2015. Two independent reviewers rated trial quality and extracted trial data. Comparative effects were summarised as standardised mean differences (SMD) and 95% confidence intervals. Pooled effect sizes were calculated using a random-effects model for three contrasts of online versus (i) interactive workshops (ii) taught lectures and (iii) written/electronic manuals. RESULTS: We included 14 studies with a total of 1089 participants. Most trials studied medical professionals, used a workshop or lecture comparison, were of high risk of bias and had small sample sizes (range 21-183). Using the GRADE approach, we found low quality evidence that there was no difference between online training and an interactive workshop for clinical behaviour SMD 0.12 (95% CI -0.13 to 0.37). We found very low quality evidence of no difference between online methods and both a workshop and lecture for knowledge (workshop: SMD 0.04 (95% CI -0.28 to 0.36); lecture: SMD 0.22 (95% CI: -0.08, 0.51)). Lastly, compared to a manual (n = 3/14), we found very low quality evidence that online methods were superior for knowledge SMD 0.99 (95% CI 0.02 to 1.96). There were too few studies to draw any conclusions on the effects of online training for practical skills, self-efficacy, and satisfaction across all contrasts. CONCLUSIONS: It is likely that online methods may be as effective as alternative methods for training HCPs in clinical interventions for the outcomes of knowledge and clinical behaviour. However, the low quality of the evidence precludes drawing firm conclusions on the relative effectiveness of these training methods. Moreover, the confidence intervals around our effect sizes were large and could encompass important differences in effectiveness. More robust, adequately powered RCTs are needed. PMID- 29169394 TI - Physical activity and activity space in patients with pulmonary fibrosis not prescribed supplemental oxygen. AB - BACKGROUND: Patients with pulmonary fibrosis (PF) have impaired quality of life, and research suggests that dyspnea and physical activity are primary drivers. As PF progresses, some patients notice the disease "shrinks their worlds". The objective of this study is to describe movement (both physical activity and activity space) in a cohort of patients with PF of various etiologies who have not been prescribed supplemental oxygen (O2). METHODS: Subjects with PF not on supplemental O2 during the day were enrolled from across the U.S. from August 2013 to October 2015. At enrollment, each subject completed questionnaires and, for seven consecutive days, wore an accelerometer and GPS tracker. RESULTS: One hundred ninety-four subjects had a confirmed diagnosis of PF and complete, analyzable GPS data. The cohort was predominantly male (56%), Caucasian (95%) and had idiopathic pulmonary fibrosis (30%) or connective tissue disease related-PF (31%). Subjects walked a median 7497 (interquartile range [IQR] 5766-9261) steps per day. Steps per day were correlated with symptoms and several quality of life domains. In a model controlling for age, body mass index, wrist- (vs. waist) worn accelerometer and percent predicted diffusing capacity (DLCO%), fatigue (beta coefficient = -51.5 +/- 11.7, p < 0.0001) was an independent predictor of steps per day (model R2=0.34). CONCLUSIONS: Patients with PF, who have not been prescribed O2 for use during the day, have wide variability in their mobility. Day-to-day physical activity is related to several domains that impact quality of life, but GPS-derived activity space is not. Wearable data collection devices may be used to determine whether and how therapeutic interventions impact movement in PF patients. TRIAL REGISTRATION: NCT01961362 . Registered 9 October, 2013. PMID- 29169395 TI - Genome-wide analysis of E. coli cell-gene interactions. AB - BACKGROUND: The pursuit of standardization and reliability in synthetic biology has achieved, in recent years, a number of advances in the design of more predictable genetic parts for biological circuits. However, even with the development of high-throughput screening methods and whole-cell models, it is still not possible to predict reliably how a synthetic genetic construct interacts with all cellular endogenous systems. This study presents a genome-wide analysis of how the expression of synthetic genes is affected by systematic perturbations of cellular functions. We found that most perturbations modulate expression indirectly through an effect on cell size, putting forward the existence of a generic Size-Expression interaction in the model prokaryote Escherichia coli. RESULTS: The Size-Expression interaction was quantified by inserting a dual fluorescent reporter gene construct into each of the 3822 single gene deletion strains comprised in the KEIO collection. Cellular size was measured for single cells via flow cytometry. Regression analyses were used to discriminate between expression-specific and gene-specific effects. Functions of the deleted genes broadly mapped onto three systems with distinct primary influence on the Size-Expression map. Perturbations in the Division and Biosynthesis (DB) system led to a large-cell and high-expression phenotype. In contrast, disruptions of the Membrane and Motility (MM) system caused small-cell and low-expression phenotypes. The Energy, Protein synthesis and Ribosome (EPR) system was predominantly associated with smaller cells and positive feedback on ribosome function. CONCLUSIONS: Feedback between cell growth and gene expression is widespread across cell systems. Even though most gene disruptions proximally affect one component of the Size-Expression interaction, the effect therefore ultimately propagates to both. More specifically, we describe the dual impact of growth on cell size and gene expression through cell division and ribosomal content. Finally, we elucidate aspects of the tight control between swarming, gene expression and cell growth. This work provides foundations for a systematic understanding of feedbacks between genetic and physiological systems. PMID- 29169396 TI - Apolipoprotein E gene polymorphism modifies fasting total cholesterol concentrations in response to replacement of dietary saturated with monounsaturated fatty acids in adults at moderate cardiovascular disease risk. AB - BACKGROUND: Consumption of <=10% total energy from fat as saturated fatty acids (SFA) is recommended for cardiovascular disease risk reduction in the UK; however there is no clear guidance on the optimum replacement nutrient. Lipid-associated single-nucleotide polymorphisms (SNPs) have been shown to modify the lipid responses to dietary fat interventions. Hence, we performed a retrospective analysis in 120 participants from the Dietary Intervention and VAScular function (DIVAS) study to investigate whether lipoprotein lipase (LPL) and apolipoprotein E (APOE) SNPs modify the fasting lipid response to replacement of SFA with monounsaturated (MUFA) or n-6 polyunsaturated (PUFA) fatty acids. METHODS: The DIVAS study was a randomized, single-blinded, parallel dietary intervention study performed in adults with a moderate cardiovascular risk who received one of three isoenergetic diets rich in SFA, MUFA or n-6 PUFA for 16 weeks. RESULTS: After the 16-week intervention, a significant diet-gene interaction was observed for changes in fasting total cholesterol (P = 0.001). For the APOE SNP rs1064725, only TT homozygotes showed a significant reduction in total cholesterol after the MUFA diet (n = 33; -0.71 +/- 1.88 mmol/l) compared to the SFA (n = 38; 0.34 +/- 0.55 mmol/l) or n-6 PUFA diets (n = 37; -0.08 +/- 0.73 mmol/l) (P = 0.004). None of the interactions were statistically significant for the other SNPs. CONCLUSIONS: In summary, our findings have demonstrated a greater sensitivity of the APOE SNP rs1064725 to dietary fat composition, with a total cholesterol lowering effect observed following substitution of SFA with MUFA but not n-6 PUFA. Further large intervention studies incorporating prospective genotyping are required to confirm or refute our findings. TRIAL REGISTRATION: The trial was registered at www.clinicaltrials.gov as NCT01478958. PMID- 29169397 TI - Application of discrete choice experiments to enhance stakeholder engagement as a strategy for advancing implementation: a systematic review. AB - BACKGROUND: One of the key strategies to successful implementation of effective health-related interventions is targeting improvements in stakeholder engagement. The discrete choice experiment (DCE) is a stated preference technique for eliciting individual preferences over hypothetical alternative scenarios that is increasingly being used in health-related applications. DCEs are a dynamic approach to systematically measure health preferences which can be applied in enhancing stakeholder engagement. However, a knowledge gap exists in characterizing the extent to which DCEs are used in implementation science. METHODS: We conducted a systematic literature search (up to December 2016) of the English literature to identify and describe the use of DCEs in engaging stakeholders as an implementation strategy. We searched the following electronic databases: MEDLINE, Econlit, PsychINFO, and the CINAHL using mesh terms. Studies were categorized according to application type, stakeholder(s), healthcare setting, and implementation outcome. RESULTS: Seventy-five publications were selected for analysis in this systematic review. Studies were categorized by application type: (1) characterizing demand for therapies and treatment technologies (n = 32), (2) comparing implementation strategies (n = 22), (3) incentivizing workforce participation (n = 11), and (4) prioritizing interventions (n = 10). Stakeholders included providers (n = 27), patients (n = 25), caregivers (n = 5), and administrators (n = 2). The remaining studies (n = 16) engaged multiple stakeholders (i.e., combination of patients, caregivers, providers, and/or administrators). The following implementation outcomes were discussed: acceptability (n = 75), appropriateness (n = 34), adoption (n = 19), feasibility (n = 16), and fidelity (n = 3). CONCLUSIONS: The number of DCE studies engaging stakeholders as an implementation strategy has been increasing over the past decade. As DCEs are more widely used as a healthcare assessment tool, there is a wide range of applications for them in stakeholder engagement. The DCE approach could serve as a tool for engaging stakeholders in implementation science. PMID- 29169398 TI - Identifying accessible prognostic factors for breast cancer relapse: a case-study on 405 histologically confirmed node-negative patients. AB - BACKGROUND: Histologically, node-negative breast cancer generally have a good prognosis. However, 10 to 30% of the cases present local relapses or metastasis. This group of people has high chances of remission if detected early. The aim of this study is to identify financial affordability for developing countries to adjust treatment. METHODS: We selected 405 patients with histologically confirmed node-negative breast cancer in our institution between January 2001 and December 2003. Patients with metastasis were excluded. The statistical analysis was conducted using SPSS ver. 18 (SPSS, Inc., Chicago, Illinois). RESULTS: The medial age was 51 years old. The medial tumor size was 35.4 mm. Clinically, 67.2% of the patients were staged cT2 and 63.2%, cN1i. Breast conservation was achieved in 41% of cases. In the histologic examination, the medial size was 30 mm. Grade III tumors were found in 50.1% of patients and positive hormonal receptors in 53.4%. The mean number of lymph nodes was 14. Eight patients had neoadjuvant chemotherapy. Adjuvant locoregional radiation and adjuvant chemotherapy were prescribed respectively in 70.6 and 64.4% of cases. 59.7% had adjuvant hormonal therapy. The follow-up showed 17.7% cases of relapse either locally or in a metastatic way in a mean time of 57.4 months. The disease-free survival at 5 years was 82.1%, and the overall survival for the same period was 91.5%. The histologic tumor size and the grade and number of lymph node dissected were shown to be influencing the disease-free survival. Radiation therapy and hormone therapy showed improved disease-free survival and overall survival. CONCLUSION: Our study found interesting results that may help personalize the treatment especially for patient living in underdeveloped countries, but further studies are needed to evaluate those and more accessible prognostic factors for a more accessible healthcare. PMID- 29169399 TI - The effects of using the PReDicT Test to guide the antidepressant treatment of depressed patients: study protocol for a randomised controlled trial. AB - BACKGROUND: Antidepressant medication is commonly used to treat depression. However, many patients do not respond to the first medication prescribed and improvements in symptoms are generally only detectable by clinicians 4-6 weeks after the medication has been initiated. As a result, there is often a long delay between the decision to initiate an antidepressant medication and the identification of an effective treatment regimen. Previous work has demonstrated that antidepressant medications alter subtle measures of affective cognition in depressed patients, such as the appraisal of facial expression. Furthermore, these cognitive effects of antidepressants are apparent early in the course of treatment and can also predict later clinical response. This trial will assess whether an electronic test of affective cognition and symptoms (the Predicting Response to Depression Treatment Test; PReDicT Test) can be used to guide antidepressant treatment in depressed patients and, therefore, hasten treatment response compared to a control group of patients treated as usual. METHODS/DESIGN: The study is a randomised, two-arm, multi-centre, open-label, clinical investigation of a medical device, the PReDicT Test. It will be conducted in five European countries (UK, France, Spain, Germany and the Netherlands) in depressed patients who are commencing antidepressant medication. Patients will be randomised to treatment guided by the PReDicT Test (PReDicT arm) or to Treatment as Usual (TaU arm). Patients in the TaU arm will be treated as per current standard guidelines in their particular country. Patients in the PReDicT arm will complete the PReDicT Test after 1 (and if necessary, 2) weeks of treatment. If the test indicates non-response to the treatment, physicians will be advised to immediately alter the patient's antidepressant therapy by dose escalation or switching to another compound. The primary outcome of the study is the proportion of patients showing a clinical response (defined as 50% or greater decrease in baseline scores of depression measured using the Quick Inventory of Depressive Symptoms - Self-Rated questionnaire) at week 8. Health economic and acceptability data will also be collected and analysed. DISCUSSION: This trial will test the clinical efficacy, cost-effectiveness and acceptability of using the novel PReDicT Test to guide antidepressant treatment selection in depressed patients.

PMID- 29169400 TI - Hypermethylation and loss of retinoic acid receptor responder 1 expression in human choriocarcinoma. AB - BACKGROUND: Human placental development resembles tumorigenesis, due to the invasive and fusogenic potential of trophoblasts. However, these features are tightly controlled in trophoblasts. Disturbance of this spatial and temporal regulation is thought to contribute to the rare formation of choriocarcinomas. Promoter hypermethylation and loss of the tumor suppressor Retinoic acid receptor responder 1 (RARRES1) were shown to contribute to cancer progression. Our study investigated the epigenetic and transcriptional regulation of RARRES1 in healthy human placenta in comparison to choriocarcinoma cell lines and cases. METHODS: Three choriocarcinoma cell lines (Jeg-3, JAR and BeWo) were treated with three different retinoic acid derivates (Am580, Tazarotene and all-trans retinoic acid) and 5-aza-2'-deoxycytidine. We analyzed RARRES1 promoter methylation by pyrosequencing and performed realtime-PCR quantification to determine RARRES1 expression in placental tissue and trophoblastic cell lines. Additionally, RARRES1 was stained in healthy placentas and in biopsies of choriocarcinoma cases (n = 10) as well as the first trimester trophoblast cell line Swan71 by immunofluorescence and immunohistochemistry. RESULTS: In the choriocarcinoma cell lines, RARRES1 expression could not be induced by sole retinoic acid treatment. Stimulation with 5-aza-2'-deoxycytidine significantly induced RARRES1 expression, which then could be further increased with Am580, Tazarotene and all-trans retinoic acid. In comparison to healthy placenta, choriocarcinoma cell lines showed a hypermethylation of the RARRES1 promoter, which correlated with a reduced RARRES1 expression. In concordance, RARRES1 protein expression was lost in choriocarcinoma tissue. Additionally, in the trophoblastic cell line Swan71, we found a significant induction of RARRES1 expression with increased cell density, during mitosis and in syncytial knots. CONCLUSIONS: Our findings showed that RARRES1 expression is absent in choriocarcinoma due to promoter methylation. Based on our analysis, we hypothesize that RARRES1 might exert tumor suppressive functions in multiple cellular processes (e.g. cell cycle regulation, adhesion, invasion and apoptosis). PMID- 29169401 TI - Treatment of splenic trauma in Norway: a retrospective cohort study. AB - BACKGROUND: Non-operative management of splenic injuries has become the treatment of choice in hemodynamically stable patients over the last decades. The aim of the study is to describe the incidence, initial treatment and early outcome of patients with splenic injuries on a national level. METHODS: All hospitals in Norway admitting trauma patients were invited to participate in the study. The study period was January through December 2013. The hospitals delivered anonymous data on primarily admitted patients with splenic injury. RESULTS: Three of the four regional trauma centers and 26 of the remaining 33 acute care hospitals delivered data on a total of 151 patients with splenic injury indicating an incidence of 4 splenic injuries per 100,000 inhabitants/year, and a median of 4 splenic injuries per hospital per year. A total of 128 (85%) patients were successfully treated non-operatively including 20 patients who underwent an angiographic procedure. The remaining 23 (15%) patients underwent open splenectomy or spleen-preserving surgery. CONCLUSION: Most patients with splenic injuries are managed non-operatively. Despite the low number of splenic injuries per hospital, the results indicate satisfactory outcome on a national level. PMID- 29169402 TI - Age, exercise, and the outcome of sepsis.

PMID- 29169403 TI - Improving health promotion through central rating of interventions: the need for Responsive Guidance. AB - BACKGROUND: In several countries, attempts are made to improve health promotion by centrally rating the effectiveness of health promotion interventions. The Dutch Effectiveness Rating System (ERS) for health promotion interventions is an improvement-oriented approach in which multi-disciplinary expert committees rate available health promotion interventions as 'theoretically sound', 'probably effective' or 'proven effective'. The aim of this study is to explore the functioning of the ERS and the perspective of researchers, policy-makers and practitioners regarding its contribution to improvement. METHODS: We interviewed 53 selected key informants from research, policy and practice in the Netherlands and observed the assessment of 12 interventions. RESULTS: Between 2008 and 2012, a total of 94 interventions were submitted to the ERS, of which 23 were rejected, 58 were rated as 'theoretically sound', 10 were rated as 'probably effective' and 3 were rated as 'proven effective'. According to participants, the ERS was intended to facilitate both the improvement of available interventions and the improvement of health promotion in practice. While participants expected that describing and rating interventions promoted learning and enhanced the transferability of interventions, they were concerned that the ERS approach was not suitable for guiding intervention development and improving health promotion in practice. The expert committees that assessed the interventions struggled with a lack of norms for the relevance of effects and questions about how effects should be studied and rated. Health promotion practitioners were concerned that the ERS neglected the local adaptation of interventions and did not encourage the improvement of aspects like applicability and costs. Policy-makers and practitioners were worried that the lack of proven effectiveness legitimised cutbacks rather than learning and advancing health promotion. CONCLUSION: While measuring and centrally rating the effectiveness of interventions can be beneficial, the evidence based-inspired ERS approach is too limited to guide both intervention development and the improvement of health promotion in practice. To better contribute to improving health promotion, a more reflexive and responsive guidance approach is required, namely one which stimulates the improvement of different intervention aspects, provides targeted recommendations to practitioners and provides feedback to those who develop and rate interventions. PMID- 29169404 TI - A mechanistic study of Toxoplasma gondii ROP18 inhibiting differentiation of C17.2 neural stem cells. AB - BACKGROUND: Congenital infection of Toxoplasma gondii is an important factor causing birth defects. The neural stem cells (NSCs) are found to be one of the target cells for the parasite during development of the brain. As a key virulence factor of the parasite that hijacks host cellular functions, ROP18 has been demonstrated to mediate the inhibition of host innate and adaptive immune responses through specific binding different host immunity related molecules. However, its pathogenic actions in NSCs remain elusive. RESULTS: In the present study, ROP18 recombinant adenovirus (Ad-ROP18) was constructed and used to infect C17.2 NSCs. After 3d- or 5d-culture in differentiation medium, the differentiation of C17.2 NSCs and the activity of the Wnt/beta-catenin signaling pathway were detected. The results showed that the protein level of betaIII tubulin, a marker of neurons, in the Ad-ROP18-transfected C17.2 NSCs was significantly decreased, indicating that the differentiation of C17.2 NSCs was inhibited by the ROP18. The beta-catenin level in the Ad-ROP18-transfected C17.2 NSCs was found to be lower than that in the Ad group. Also, neurogenin1 (Ngn1) and neurogenin2 (Ngn2) were downregulated significantly (P < 0.05) in the Ad ROP18-transfected C17.2 NSCs compared to the Ad group. Accordingly, the TOP flash/FOP flash dual-luciferase report system showed that the transfection of Ad ROP18 decreased the Wnt/beta-catenin pathway activity in the C17.2 NSCs. CONCLUSIONS: The inhibition effect of the ROP18 from T. gondii (TgROP18) on the neuronal differentiation of C17.2 NSCs was at least partly mediated through inhibiting the activity of the Wnt/beta-catenin signaling pathway, eventually resulting in the downregulation of Ngn1 and Ngn2. The findings help to better understand potential mechanisms of brain pathology induced by TgROP18. PMID- 29169405 TI - Atypical Creutzfeldt-Jakob disease with PrP-amyloid plaques in white matter: molecular characterization and transmission to bank voles show the M1 strain signature. AB - Amyloid plaques formed by abnormal prion protein (PrPSc) aggregates occur with low frequency in Creutzfeldt-Jakob disease, but represent a pathological hallmark of three relatively rare disease histotypes, namely variant CJD, sporadic CJDMV2K (methionine/valine at PRNP codon 129, PrPSc type 2 and kuru-type amyloid plaques) and iatrogenic CJDMMiK (MM at codon 129, PrPSc of intermediate type and kuru plaques). According to recent studies, however, PrP-amyloid plaques involving the subcortical and deep nuclei white matter may also rarely occur in CJDMM1 (MM at codon 129 and PrPSc type 1), the most common CJD histotype.To further characterize the phenotype of atypical CJDMM1 with white matter plaques (p CJDMM1) and unravel the basis of amyloid plaque formation in such cases, we compared clinical and histopathological features and PrPSc physico-chemical properties between 5 p-CJDMM1 and 8 typical CJDMM1 brains lacking plaques. Furthermore, transmission properties after bioassay in two genetic lines of bank voles were also explored in the two groups.All 5 p-CJDMM1 cases had a disease duration longer than one year. Three cases were classified as sporadic CJDMM1, one as sporadic CJDMM1 + 2C and one as genetic CJDE200K-MM1. Molecular mass, protease sensitivity and thermo-solubilization of PrPSc aggregates did not differ between p-CJDMM1 and classical CJDMM1 cases. Likewise, transmission properties such as incubation time, lesion profile and PrPSc properties in bank voles also matched in the two groups.The present data further define the clinical-pathologic phenotype of p-CJDMM1, definitely establish it as a distinctive CJD histotype and demonstrate that PrP-plaque formation in this histotype is not a strain-specific feature. Since cases lacking amyloid plaques may also manifest a prolonged (i.e. > than one year) disease course, unidentified, host-specific factors likely play a significant role, in addition to disease duration, in generating white matter PrP-amyloid plaques in p-CJDMM1. PMID- 29169406 TI - Extracellular cathepsin L stimulates axonal growth in neurons. AB - OBJECTIVE: Cathepsin L, a lysosomal endopeptidase expressed in most eukaryotic cells, is a member of the papain-like family of cysteine proteases. Although commonly recognized as a lysosomal protease, cathepsin L is also secreted and involved in the degradation of extracellular matrix proteins. Previous studies demonstrated that the secretion of cathepsin L was stimulated by basic fibroblast growth factor (bFGF) and bFGF-enhanced axonal terminal sprouting of motor neurons. Based on these results, although it has never been directly investigated, we hypothesized that extracellular cathepsin L may induce axonal growth. RESULTS: To confirm the hypothesis, the axonal growth activity of recombinant cathepsin L was evaluated in cultured cortical and spinal cord neurons. Treatment with recombinant cathepsin L significantly enhanced axonal growth, but not dendritic growth. This result indicated that extracellular cathepsin L may act as a new neuronal network modulator. PMID- 29169409 TI - Characteristic pro-inflammatory cytokines and host defence cathelicidin peptide produced by human monocyte-derived macrophages infected with Neospora caninum. AB - Neospora caninum is a coccidian intracellular protozoan capable of infecting a wide range of mammals, although severe disease is mostly reported in dogs and cattle. Innate defences triggered by monocytes/macrophages are key in the pathogenesis of neosporosis, as these cells are first-line defenders against intracellular infections. The aim of this study was to characterize infection and innate responses in macrophages infected with N. caninum using a well-known cell model to study macrophage functions (human monocyte THP-1 cells). Intracellular invasion of live tachyzoites occurred as fast as 4 h (confirmed with immunofluorescence microscopy using N. caninum-specific antibodies). Macrophages infected by N. caninum had increased expression of pro-inflammatory cytokines (TNFalpha, IL-1beta, IL-8, IFNgamma). Interestingly, N. caninum induced expression of host-defence peptides (cathelicidins), a mechanism of defence never reported for N. caninum infection in macrophages. The expression of cytokines and cathelicidins in macrophages invaded by N. caninum was mediated by mitogen activated protein kinase (MEK 1/2). Secretion of such innate factors from N. caninum-infected macrophages reduced parasite internalization and promoted the secretion of pro-inflammatory cytokines in naive macrophages. We concluded that rapid invasion of macrophages by N. caninum triggered protective innate defence mechanisms against intracellular pathogens. PMID- 29169407 TI - The clinical significance of plasma clusterin and Abeta in the longitudinal follow-up of patients with Alzheimer's disease. AB - BACKGROUND: Clusterin and beta-amyloid (Abeta) are involved in the pathogenesis of Alzheimer's disease (AD). The clinical significance of plasma clusterin and Abeta in AD progression remains controversial. METHODS: We recruited 322 patients with AD and 88 controls between August 2012 and June 2013. All participants were evaluated at baseline with a clinical assessment, Mini-Mental State Examination (MMSE), and Clinical Dementia Rating (CDR) scales. Patients with AD were evaluated annually with the MMSE and Neuropsychiatric Inventory (NPI) scale during the 2-year follow-up period. The levels of plasma clusterin, Abeta1-40, and Abeta1-42 at baseline were analyzed to study the longitudinal changes in the patient scores on the MMSE and NPI during the follow-up period. RESULTS: Patients in the highest tertile of plasma clusterin levels showed significantly lower MMSE scores than those in the lowest tertile (p = 0.04). After adjustment for multiple covariates using the generalized estimating equation analysis, there was a significant decrease in the MMSE scores over the 2-year follow-up period among AD patients in the highest tertile of plasma clusterin levels compared with those in the lowest tertile (-2.09, 95% confidence interval (CI) = -3.67 to -0.51, p = 0.01). In apolipoprotein E (ApoE)4-positive AD patients, baseline measurements of the ratio of plasma Abeta1-42/Abeta1-40 in the highest tertile predicted an increase in NPI agitation/aggression scores over the 2-year follow-up period (6.06, 95% CI = 1.20-10.62, p = 0.02). CONCLUSIONS: Plasma clusterin could serve as a biomarker for the severity of cognitive decline. Plasma Abeta in ApoE4 positive AD could predict long-term agitation/aggression symptoms. PMID- 29169408 TI - The bacterial interlocked process ONtology (BiPON): a systemic multi-scale unified representation of biological processes in prokaryotes. AB - BACKGROUND: High-throughput technologies produce huge amounts of heterogeneous biological data at all cellular levels. Structuring these data together with biological knowledge is a critical issue in biology and requires integrative tools and methods such as bio-ontologies to extract and share valuable information. In parallel, the development of recent whole-cell models using a systemic cell description opened alternatives for data integration. Integrating a systemic cell description within a bio-ontology would help to progress in whole cell data integration and modeling synergistically. RESULTS: We present BiPON, an ontology integrating a multi-scale systemic representation of bacterial cellular processes. BiPON consists in of two sub-ontologies, bioBiPON and modelBiPON. bioBiPON organizes the systemic description of biological information while modelBiPON describes the mathematical models (including parameters) associated with biological processes. bioBiPON and modelBiPON are related using bridge rules on classes during automatic reasoning. Biological processes are thus automatically related to mathematical models. 37% of BiPON classes stem from different well-established bio-ontologies, while the others have been manually defined and curated. Currently, BiPON integrates the main processes involved in bacterial gene expression processes. CONCLUSIONS: BiPON is a proof of concept of the way to combine formally systems biology and bio-ontology. The knowledge formalization is highly flexible and generic. Most of the known cellular processes, new participants or new mathematical models could be inserted in BiPON. Altogether, BiPON opens up promising perspectives for knowledge integration and sharing and can be used by biologists, systems and computational biologists, and the emerging community of whole-cell modeling. PMID- 29169410 TI - miR-767-3p Inhibits Growth and Migration of Lung Adenocarcinoma Cells by Regulating CLDN18. AB - Claudin18 (CLDN18) is necessary for intercellular junctions and is reported to be involved in cell migration and metastasis, making it like an oncogene in various cancer types. However, the biological function and regulatory mechanisms of CLDN18 in lung adenocarcinoma are not yet clear. In this study, we found downregulation of miR-767-3p and upregulation of CLDN18 in lung adenocarcinoma tissue and cell lines. In addition, there was a negative correlation between the expression of miR-767-3p and CLDN18 in lung adenocarcinoma. Double luciferase reporter gene analysis showed that miR-767-3p modulates the expression of CLDN18 by binding its 3'-untranslated regions (3'-UTR). Knockdown of CLDN18 results in a decrease in the growth, migration, and invasion of lung adenocarcinoma cells. Although overexpression of miR-767-3p inhibits lung adenocarcinoma cell growth and migration, these effects can be rescued by reexpressing CLDN18. In summary, the data suggest that miR-767-3p inhibits tumor cell proliferation, migration, and invasion by targeting CLDN18, providing a promising therapeutic target for lung adenocarcinoma.

Methods Male BALB/c mice were randomly divided into normal control group, ovalbumin (OVA) asthma group, 1, 5, 15 mg/mL PM2.5 treated OVA asthma group. The bronchoalveolar lavage fluid (BALF) was collected and the number of white blood cells was observed by Gimsa staining. ELISA was used to determine the concentrations of serum cytokines interferon gamma (IFN-gamma), interleukin 17 (IL-17) and IL-10 in the peripheral blood of mice. Real-time quantitative PCR was performed to detect the mRNA expression levels of Toll-like receptor 4 (TLR4), nuclear factor-kappaB (NF-kappaB) in peripheral blood mononuclear cells (PBMCs). The levels of T-bet, RORgammat and FOXP3 were tested by Western blotting. The lung tissues were collected and the pathological changes were observed by HE staining. Results Compared with the normal control group, the OVA asthma group showed thickened alveolar septum, enlarged alveolar cavity and more obvious inflammatory cell infiltration, as well as significantly increased white blood cells associated with inflammatory response in the BALF. Whereas, compared with the OVA asthma group, the above mentioned changes in 15 mg/mL PM2.5 treated OVA asthma group were extremely obvious. ELISA showed that the levels of IFN-gamma and IL-10 in the serum of the OVA asthma group were significantly lower than those in the control group, while IL-17 significantly increased. Compared with the OVA asthma group, the levels of IFN-gamma and IL-10 in 15 mg/mL PM2-treated OVA asthma group significantly decreased, while the content of IL-17 significantly increased. Real time quantitative PCR showed that the expressions of TLR4 and NF-kappaB in PBMCs of the OVA asthma group were significantly higher than those in the control group. In 15 mg/mL PM2.5-treated OVA asthma group, the levels of TLR4 and NF kappaB increased significantly as compared with the OVA asthma group. Compared with the control group, the expressions of T-bet and FOXP3 proteins in the OVA asthma group were significantly lower than those in the control group, and the expression of RORgammat protein was significantly increased. Compared with the OVA asthma group, the levels of T-bet and FOXP3 proteins were reduced a lot in 15 mg/mL PM2.5-treated OVA asthma group, while RORgammat protein level was remarkably elevated. Conclusion The 15 mg/mL PM2.5 can obviously promote OVA induced asthma and even lung injury by activating the TLR4/NF-kappaB signaling pathway.

AB - Objective To determine whether tumor necrosis factor alpha (TNF-alpha) regulates the proliferation of MCF-7 and MDA-MB231 cells by modifying ceramide (Cer) production. Methods The optimum dosage and time of TNF-alpha treatment was determined at first. Immunocytochemistry combined with confocal microcopy was adopted to measure Cer content. MCF-7 and MDA-MB231 cells were treated with TNF alpha (50 ng/mL) alone or combined with the interference of ASM inhibitor, desipramine (Des) or sphingosine kinase 1 (SPHK1) inhibitor, dimethylsphingosine (DMS) to investigate the role of Cer in the proliferative regulation of TNF-alpha on breast cancer cells. MTT assay was used to determine the proliferation of the cancer cells and Western blotting was performed to measure the protein expressions of acid sphingomyelinase (ASM), SPHK1 and apoptosis or proliferation relevant factors including Bcl2, Bax and proliferating cell nuclear antigen (PCNA). Results TNF-alpha reduced the proliferation of MCF-7 cells, but enhanced the growth of MDA-MB-231 cells in a time- and dose-dependent manner. After TNF alpha treatment, the protein expression of ASM, but not SPHK1 increased in MCF-7 cells, but both of them were elevated in MDA-MB-231 cells. Accordingly, Cer content was increase in MCF-7 cells treated by TNF-alpha, which was blocked by the pretreatment of ASM inhibitor Des. Cer content in MDA-MB231 cells was reduced by TNF-alpha, which was prevented by the pretreatment of SPHK1 inhibitor DMS. Des and DMS could respectively reverse the TNF-alpha-induced decrease and increase of proliferation in MCF-7 and MDA-MB-231 cells. Moreover, the protein expression of Bcl2 decreased and Bax increased in MCF-7 cells, and the protein expression of PCNA increased in MDA-MB231 cells after TNF-alpha treatment. Conclusion TNF-alpha can alter Cer production by regulating the expressions of ASM and SPHK1 to control the proliferation of MCF-7 and MDA- MB231 cells.

AB - Objective To study the effect of Notch1 signaling on the release of inflammatory mediators in lipopolysaccharide (LPS)-induced macrophages and the related mechanism. Methods The expressions of Notch1 and hairy and enhancer of split 1 (Hes1) mRNAs were investigated by reverse transcription PCR (RT-PCR) in mouse RAW264.7 cells after stimulated with 100 ng/mL LPS for 8 hours. Prior to stimulation with LPS, mouse RAW264.7 cells were treated with DAPT (10 MUmol/L), an inhibitor of Notch1 signaling, for 1 hour. The concentrations of tumor necrosis factor (TNF-alpha), interleukin 1beta (IL-1beta), IL-6, nitric oxide (NO) and prostaglandin E2 (PGE2) in cell culture media were measured by ELISA. The mRNA levels of nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were examined by RT-PCR. The protein levels of iNOS, COX-2, nuclear factor kappa Bp65 (NF-kappaBp65) and phosphorylated nuclear factor kappaB inhibitor alpha (p IkappaBalpha) were detected by Western blotting. Results The expressions of Notch1 and Hes1 mRNAs significantly increased in mouse RAW264.7 cells after stimulated with LPS. The levels of TNF-alpha, IL-1beta, IL-6, NO and PGE2 were significantly up-regulated in cell culture media after stimulated with LPS, but the levels of those inflammatory mediators were reduced by DAPT. The mRNA and protein levels of iNOS and COX-2 were significant raised in mouse RAW264.7 cells after stimulated with LPS, while they were inhibited by DAPT. Both IkappaBalpha phosphorylation and NF-kappaBp65 translocation into nuclear in LPS-induced RAW264.7 cells were also inhibited by DAPT. Conclusion Notch1 signaling activates NF-kappaB to participate in LPS-induced inflammatory mediator release in macrophages.

AB - Objective To investigate the protective effect of lentivirus-mediated BI-1 overexpression on hippocampal neurons in rats with subarachnoid hemorrhage (SAH) and the relationship with endoplasmic reticulum IRE1-JNK signaling pathway. Methods The lentivirus solution of BI-1 over-expression was injected into the brain of rats 24 hours before SAH rat model was established by intravascular puncture method. At 24 hours after modeling, the brain water content and neurological score of the rats were measured. The apoptosis of hippocampal neurons was detected by TUNEL assay. Western blotting was used to detect the expressions of BI-1 protein and endoplasmic reticulum stress (ERS) marker proteins GRP78 and IRE1. ERS in hippocampal neurons of the rats with SAH was intervened by IRE1alpha-specific inhibitor KIRA6, and then the protein expressions of p-IRE1, p-JNK, Bax, Bcl2 and caspase-3 were detected by Western blotting. Results BI-1 over-expression improved neurobehavioral score, decreased brain water content and hippocampal neuron apoptosis rate, and also down regulated GRP78 and IRE1 protein levels in the rats with SAH. Both the interference of KIRA6 and the over-expression of BI-1 inhibited the expressions of p-IRE1, p-JNK, Bax and caspase-3, and promoted the expression of anti apoptotic protein Bcl2. Conclusion Over-expression of BI-1 can inhibit the apoptosis of hippocampal neurons in rats with SAH by inhibiting the activation of ERS-mediated IRE1-JNK signaling pathway, thus ultimately attenuating the early brain injury following SAH.

AB - Objective To investigate the effect of thioredoxin interacting protein (TXNIP) over-expression on the apoptosis of MIN6 beta-cells and the mechanism involved. Methods Lentivirus carrying TXNIP gene was used to infect MIN6 beta-cells in logarithmic growth phase, and the infection efficiency was evaluated by fluorescence microscope and Western blotting. Then MIN6 beta-cells were divided into three groups: control group, empty lentivirus vector (LV-GFP) group and TXNIP over-expression (LV-GFP-TXNIP) group. CCK-8 assay was used to detect cell proliferation. AnnexinV-FITC/PI double staining was utilized to measure the apoptosis of MIN6 cells. Western blotting was applied to detect the expressions of TXNIP protein, TRX, Bax, Bcl2, cleaved caspase-3 (c-caspase-3), p38 mitogen activated protein kinase (p38MAPK), phospho-p38MAPK (p-p38MAPK) proteins in the MIN6 beta-cells before and after treated with p38MAPK inhibitor SP169316. Results At 72 hours after the infection, the infection rate reached (87.10+/-2.30)% and (92.21+/-0.54)% in LV-GFP group and LV-GFP-TXNIP group, respectively, suggesting that lentivirus-mediated TXNIP over-expression was desirable. Compared with control group and LV-GFP group, the cell viability markedly decreased, and cell apoptosis, Bax/Bcl2 ratio, expression of c-caspased-3 and p38MAPK phosphorylation significantly increased in LV-GFP-TXNIP group. However, both the Bax/Bcl2 ratio and c-caspase-3 protein expression in LV-GFP-TXNIP group were obviously reduced after treated with p38MAPK inhibitor. Conclusion TXNIP over-expression might promote the apoptosis of MIN6 cells via activating the p38 MAPK pathway.

AB - Objective To investigate the effect of preproenkephalin-minimalistic immunologically defined gene expression-nuclear localization signal (PPENK-MIDGE NLS) vector postconditioning on mitophagy during myocardial ischemia reperfusion in rats. Methods Forty male SD rats were randomly divided into 4 groups: sham operation group, ischemia reperfusion group, PPENK-MIDGE-NLS group and Control MIDGE-NLS group. Myocardial ischemia reperfusion injury model was induced by ligating left anterior descending branch of coronary artery (LAD). Sham operation group was treated identically with the ischemia reperfusion group except that LAD was not tied and occluded. Ischemia reperfusion group, PPENK-MIDGE-NLS group, and Control-MIDGE-NLS group were treated with ligation and occlusion of LAD for 30 minutes followed by 24 hour-reperfusion, with 1.5 mL saline, or 1.5 mL PPENK MIDGE-NLS vectors (200 MUg), or 1.5 mL Control-MIDGE-NLS vectors (200 MUg) administered respectively right before reperfusion started. Serum cTnI was assayed by ELISA and myocardial infarct size was measured by TTC. Ultrastructural changes of mitochondria and mitophagy were observed using electron microscope, and mitochondrial damage scores were analyzed. Expressions of the mitophagy related proteins such as PINK1, parkin, p62, TOM20 and LC3B were measured by Western blotting. Results Compared with the ischemia reperfusion group, both serum cTnI content and myocardial infarct size in the PPENK group decreased; the expression of PINK1, parkin, p62 and LC3B were all up-regulated. Mitophagy was enhanced and mitochondrial damages were alleviated, with conspicuous improvement in mitochondria ultrastructure. Conclusion PPENK-MIDGE-NLS vector postconditioning can mitigate myocardial ischemia reperfusion injury by promoting mitophagy in rats.

AB - Objective To investigate the effect of lentivirus-mediated shRNA targeting AKT1 gene on the sensitivity of gastric cancer xenografts to doxorubicin. Methods To establish the lentiviral vector of AKT1 RNA interference (RNAi), the vector of pGCSIL-shAKT1-GFP was infected into HEK293T cells, and meanwhile, the empty vector pGCSIL-shCON-GFP was assigned as a blank group, and then the viruses were harvested. BGC-823 gastric cancer cells were infected with the viruses. The protein expression of AKT1 was detected by Western blotting. The gastric cancer xenografts in nude mice were constructed using BGC-823 cells infected with the viruses, followed by the administration of doxorubicin. The size of tumor was evaluated and the growth curve of the tumor was drawn; HE staining was used to observe the pathological conditions of the xenografts; and the apoptosis of xenografts was examined by TUNEL assay. Results The recombinant plasmid of LV shAKT1 was successfully constructed, and then transfected into HEK293T cells to produce high-titer lentivirus with a titer of 5*108 TU/mL. The expression of AKT1 protein in gastric cancer BGC-823 cells was significantly down-regulated after successfully infected with the LV-shAKT1. Nude mice xenografts experiment showed that AKT1 gene silencing inhibited the growth of tumor xenografts, and also enhanced the inhibitory effect of doxorubicin on the growth of tumor xenografts. TUNEL staining showed that AKT1 gene silencing promoted the apoptosis of tumor xenograft cells, and the effect was more obvious when combined with doxorubicin. Conclusion AKT1 gene silencing can enhance the sensitivity of gastric cancer xenografts to doxorubicin through promoting cell apoptosis.

AB - Objective To investigate the isolation and identification of extracellular vesicles (EVs) from rat bone marrow mesenchymal stem cells (BMSCs) and the effect of -80DegreesCelsius cryopreservation on the structural integrity of the EVs' membrane. Methods EVs were isolated and purified from the culture supernatant of bone marrow mesenchymal stem cells (BMSC-CS) by ultrahigh velocity centrifugation. The size and morphology of EVs were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Western blotting was performed to detect the expression of CD63 protein. The integrity of the EVs' membrane structure was observed by TEM at different time after storage at 80DegreesCelsius. Results SEM showed that a large number of EVs with membrane structures, round or oval and ranged in size from 50 to 1000 nm were attached onto BMSC surface. Under TEM, BMSC-EVs were similar in morphology and size to them under SEM. Western blotting revealed that BMSC-EV expressed the marker protein CD63. BMSC-EVs had a complete membrane structure at the first month and the third month, whereas BMSC-EV's membrane structure ruptured at the sixth month after storage at -80DegreesCelsius. Conclusion BMSC-EVs is successfully extracted, and the membrane structure integrity get worse with the prolongation of cryopreservation time.

AB - Objective To investigate the effect of exogenous hydrogen sulfide from sodium hydrosulfide (NaHS) on cardiac thioredoxin (Trx) system in diabetic rats. Methods Male Sprague-Dawley rats were randomly divided into a normal group, a diabetic group, and three NaHS (14, 28 and 56 MUmol/kg) treatment groups, with 6 rats in each group. Type 1 diabetes was induced in the groups by a single intraperitoneal (i.p.) injection of streptozotocin. At the fifth week after modeling, the NaHS treatment groups were injected (i.p.) with NaHS at the doses of 14, 28 and 56 MUmol/kg once a day, respectively. After the treatment for 4 weeks, the fasting blood glucose (FBG) level and ventricular hemodynamic parameters were measured. The changes of myocardial pathomorphology were observed by HE staining. The ultrastructural changes of cardiomyocytes were observed by transmission electron microscopy. The levels of serum lactate dehydrogenase (LDH), creatine kinase (CK), and creatine kinase MB isozyme (CK-MB) were examined using the kits. Serum interleukin (IL)-1beta, IL-6, and tumor necrosis factor alpha (TNF-alpha) were assayed by ELISA. The levels of total antioxidant capacity (T-AOC), lipid peroxide (LPO), and malondialdehyde (MDA) in myocardium were analyzed using the kits. The mRNA expression of heme oxygenase 1 (HO-1) was detected using reverse transcription PCR (RT-PCR). The expression levels of Trx, Trx-interacting protein (TXNIP), and nicotinamide adenine dinucleotide phosphate oxidase 2 (NOX2) in myocardium were measured using Western blotting. Results Compared with the normal group, the left ventricular systolic and diastolic functions were weakened in the diabetic group, and the myocardial morphological structure and ultrastructure were damaged obviously. The FBG, LDH, CK, CK-MB, IL-1beta, IL-6, TNF-alpha, LPO and MDA levels increased, while the T-AOC level decreased. The myocardial Trx protein expression was reduced, while the expressions of HO-1 mRNA, TXNIP and NOX2 proteins were elevated in the diabetic group. Compared with the diabetic group, the left ventricular systolic and diastolic functions, myocardial morphological structure and ultrastructure were improved in the three NaHS treatment groups. The LDH, CK, CK-MB, IL-1beta, IL-6, TNF-alpha, LPO and MDA levels decreased, while T-AOC increased. The myocardial HO-1 mRNA and Trx protein expressions were enhanced, while TXNIP and NOX2 protein expressions were suppressed. Conclusion NaHS treatment attenuates diabetic myocardial injury, and the mechanisms may be associated with the activation of the Trx system, the enhancement of antioxidant capability and the inhibition of inflammatory factor release.

AB - Objective To explore the relationships between the IL1B-511C/T and IL1RN+8006T/C polymorphisms and coronary heart disease (CHD) in Chinese population. Methods We analyzed case-control studies regarding the associations of the IL1B-511C/T and IL1RN+8006T/C polymorphisms with CHD in Chinese population by searching PubMed, EMBASE, VIP Database, Wanfang and China National Knowledge Infrastructure databases. All articles were rigorously evaluated and screened based on the inclusion and exclusion criteria. Meta-analysis was performed using Review Manager 5.3 software. Results Eight case-control studies with a total of 1460 CHD patients and 1547 control subjects met the inclusion criteria. The pooled results from IL1B-511C/T polymorphism showed increased risk in allelic model (OR=1.17, 95%CI=1.04-1.31), recessive model (OR=1.58, 95%CI=1.32-1.90) and homozygote model (OR=1.38, 95%CI=1.09-1.74). But for IL1RN+8006T/C polymorphism, decreased risk was observed in allelic model (OR=0.55, 95%CI=0.43-0.69), dominant model (OR=0.52, 95%CI=0.40-0.66) and heterozygote model (OR=0.51, 95%CI=0.40-0.66). Conclusion The IL1RN+8006T/C polymorphism may play a protective role in CHD. The IL1B-511C/T polymorphism is found to be associated with a significant increased risk for CHD based on our analysis.

AB - Objective To express prokaryotically the non-structural protein 1 (NS1) of duck Tembusu virus (DTMUV) and prepare NS1-specific polyclonal antibodies. Methods The NS1 gene of DTMUV strain AH-F10 was amplified by PCR, followed by subcloning and expression in the prokaryotic vector pET-32a. The recombinant NS1 protein was successfully expressed in Escherichia coli BL21 (DE3), and purified with hydroxymethyl urea and renatured by gradient centrifugation. The BALB/c mice were immunized with the purified recombinant NS1 protein to prepare polyclonal antibodies against the NS1 protein. Furthermore, the titer of the polyclonal antibodies was determined by agar diffusion test (AGP), and the specificity of the polyclonal antibodies was verified by Western blotting and indirect immunofluorescence assay (IFA). Results Polyclonal antibodies against NS1 protein in serum was successfully obtained with an AGP titer of 1:8. Western blotting and IFA demonstrated that the serum with polyclonal antibodies had a high-level specificity and reactivity to the NS1 protein of DTMUV. Conclusion Polyclonal antibodies against DTMUV NS1 protein were successfully prepared and validated in this study. PMID- 29169430 TI - Spontaneous Pneumothorax. AB - BACKGROUND: Few reliable data are available on the epidemiology and treatment of spontaneous pneumothorax. We studied the sex and age distribution, frequency of hospitalization, mortality, and conservative versus surgical care of this condition in Germany in order to draw well-founded conclusions about its in hospital diagnosis and treatment. METHODS: Data from all patients aged 10 or older who were hospitalized in the period 2011-2015 with a main discharge diagnosis of pneumothorax of neither traumatic nor iatrogenic origin were retrieved from the German Federal Statistical Office. Because of their source, all data were based on case numbers rather than patient numbers. RESULTS: During the period of the study, there were 52 738 admissions with the main diagnosis of spontaneous pneumothorax, corresponding to an annual frequency of hospitalization of 14.3 per 100 000 persons per year (95% confidence interval, 14.0 to 14.5). Men were more frequently affected than women. The lethality and in-hospital mortality of this condition (<= 0.08% and <= 0.3%, respectively) were low among persons aged 15 to 45, but markedly higher in persons over age 90 (9.4% and 15.9%, respectively). The frequency of accompanying pulmonary diagnoses also rose with age. Computerized tomography (CT) was performed in 38.9-54.6% of hospitalizations, depending on age. Monitoring on an intensive care unit was carried out in 36% of cases. More than one-quarter of cases involved surgical treatment. CONCLUSION: The danger to life and the likelihood of an accompanying pulmonary diagnosis are both low up to age 45. Treatment on an intensive care unit and computerized tomography of the chest should be performed only for strict indications in patients under age 45. The pathophysiological basis of the differing patterns of illness depending on age and sex requires further investigation. PMID- 29169432 TI - Consider the Risk of Goiter. PMID- 29169431 TI - Monoclonal IgM Gammopathy and Waldenstrom's Macroglobulinemia. AB - BACKGROUND: 3.2-3.5% of persons over age 50 have a monoclonal gammopathy. Monoclonal gammopathies have many causes, including cancer. 10-20% of monoclonal gammopathies are of isotype IgM. A systematic approach to the differential diagnosis of IgM gammopathies is essential because of the different therapeutic implications of the various underlying conditions. METHODS: This review is based on pertinent publications retrieved by a selective search in PubMed and current guidelines from Germany and abroad. RESULTS: The diagnosis of a monoclonal IgM gammopathy is established by serum electrophoresis in combination with immune fixation. Further evaluation enables the identification of the underlying condition: the differential diagnosis includes IgM-MGUS (monoclonal gammopathy of unclear significance), Waldenstrom's disease, and IgM myeloma. The therapeutic implications of the under - lying condition vary from watchful waiting in IgM MGUS to combined rituximab and antineoplastic chemotherapy (off-label first-line use of rituximab) in symptomatic Waldenstrom's macroglobulinemia. Ibrutinib has been approved for the treatment of patients with recurrences, or of those for whom first-line treatment with rituximab and chemotherapy is not suitable. The current treatment options do not result in cure. In symptomatic Waldenstrom's disease, the goal of treatment is to keep the disease under control for as long as possible without impairing the patient's quality of life. CONCLUSION: Evidence based treatment decisions in Waldenstrom's macroglobulinemia now rely mainly on small-scale, single-armed trials. Patients with this disease should be treated in the setting of a clinical trial if possible. Trials aimed at improving the quality of treatment for other IgM-associated diseases, such as IgM neuropathies and cold agglutinin disease, would also be desirable. PMID- 29169433 TI - In Reply.

PMID- 29169441 TI - Patient Selection and Counseling for Urinary Diversion. AB - Patient selection and preoperative counseling are critical aspects of determining which urinary diversion to perform and should be emphasized at each stage of preoperative planning. The surgeon must have a thorough understanding of the patient's disease process, functional and psycho-emotional status, and social support network so that they can set appropriate expectations. It is also crucial to have a multidisciplinary team of individuals who are experienced with all aspects of urinary diversion care, including ostomy nurses, nurse navigators, and urologic surgeons skilled at teaching and trouble-shooting self-catheterization for continent cutaneous diversion and orthotopic diversion in the setting of hypercontinence. PMID- 29169442 TI - Quality of Life and Urinary Diversion. AB - Health-related quality-of-life outcomes after urinary diversion vary significantly. Preserving and even improving health-related quality of life are highly relevant to urinary diversion. Life after urinary diversion is fundamentally different than before. PMID- 29169443 TI - Perioperative Preparation and Nutritional Considerations for Patients Undergoing Urinary Diversion. AB - Patients undergoing urinary diversion are at high risk for complications in the perioperative period. The exact cause of these complications remains poorly defined but is likely multifactorial. Current efforts to optimize patients in the perioperative period, including prehabilitation, smoking cessation, recognition and treatment of comorbid conditions and malnutrition, immunonutrition supplementation, carbohydrate loading, and prevention of known complications and implementation of enhanced recovery after surgery pathways, seem beneficial in helping to improve outcomes in this at-risk population. Further studies (some of which are ongoing) are necessary to help optimize these strategies and identify which modifiable factors have the greatest impact. PMID- 29169444 TI - Urinary Diversion in Renal Transplantation. AB - Renal transplantation involving anatomically or functionally altered recipient urinary reservoirs is a challenging procedure. Initial reports discouraged kidney transplantation in patients with urinary diversion due to inferior outcomes. However, more recent studies have shown that although there are more infectious complications, patients with urinary diversions have comparable long-term graft survival with those with native anatomy. Careful preoperative assessment of these candidates is mandatory. Unique technical and surgical concepts must be considered before embarking on transplanting this specific cohort of kidney transplantation candidates. PMID- 29169445 TI - Advances in Pediatric Urinary Diversion. AB - Pediatric urinary diversion is performed for a unique set of indications with many options to consider. Although surgical intervention has decreased in necessity overall due to advances in expectant management, it remains an important tool. There are many options and various factors to consider in choosing the right type of diversion for an individual and these patients require lifelong follow-up with a pediatric urologist and eventually an adult urologist. This article provides a detailed review of the most relevant techniques used by pediatric urologists for urinary diversion. PMID- 29169446 TI - Tissue Engineering and Conduit Substitution. AB - Radical cystectomy (RC) with urinary diversion is associated with significant morbidity, much of which arises from the interposition of bowel segments in the urinary system. A tissue-engineered alternative for urinary diversion could dramatically reduce the perioperative and long-term morbidity associated with RC. Attempts at developing a tissue-engineered incontinent urinary conduit (TEUC) have involved mechanical scaffolds and promoting tissue growth within them. Despite some preclinical success, significant obstacles remain before a TEUC is ready for clinical use. A further understanding of tissue and materials engineering may help overcome these obstacles or help to develop a new approach to tissue engineering entirely. PMID- 29169447 TI - Metabolic and Nutritional Consequences of Urinary Diversion Using Intestinal Segments to Reconstruct the Urinary Tract. AB - Intestinal segments in various forms have been used to reconstruct the urinary tract since the mid-1800s. Currently, many different forms of continent and incontinent diversion options exist. Incorporating bowel mucosa within the urinary tract leads to predictable metabolic and nutritional consequences. The use of ileum or colon can cause a hyperchloremic metabolic acidosis, vitamin B12 deficiency, osteoporosis, fat malabsorption, urinary calculi, and ammoniagenic encephalopathy. Due to metabolic and nutritional consequences associated with the use of jejunum and gastric segments, the use of these bowel segments is not recommended. PMID- 29169448 TI - Conduit Urinary Diversion. AB - This review summarizes the salient aspects of the ileal conduit with 3 pedagogical objectives in mind: (1) to describe the surgical steps emphasizing important surgical principles, (2) to provide insight on various preoperative and postoperative considerations, and (3) to summarize the risks of the long-term complications and quality of life. We aim to inform a broad medical readership. PMID- 29169449 TI - Male Neobladder. AB - Successful outcome with orthotopic neobladders begins in the preoperative phase with appropriate patient selection and extensive patient counseling. Meticulous attention to surgical and oncological principles is required to optimize neobladder outcomes. Long-term follow-up is needed not only for oncological purposes but also to monitor for the late complications, such as ureterointestinal strictures, renal deterioration, infections, and voiding dysfunction. PMID- 29169450 TI - Orthotopic Urinary Diversion for Women. AB - Orthotopic neobladder is a viable option for women undergoing cystectomy for bladder cancer, with excellent oncologic outcomes and a low incidence of urethral recurrence. Careful patient selection is important, as is developing a clear understanding by the patient and her family in what to expect with an orthotopic diversion. Surgical technique is also important in optimizing functional outcomes, such as continence, sexual function, and decreased rate of vaginal fistula formation, and urinary retention. PMID- 29169451 TI - Continent Cutaneous Diversion. AB - Techniques in continent cutaneous urinary diversion (CCUD) have evolved significantly over the last 30 years resulting in several well-established procedures. CCUD is well suited for patients in whom the urethra cannot be used for orthotopic diversion due to preexisting incontinence, radiation damage, or malignancy. Reservoirs are constructed with adherence to basic principles of continent urinary diversion, including the use of detubularized bowel in a spherical conformation for pouch creation with either ileum or the right colon. The article reviews the history, patient selection, preoperative evaluation, surgical technique, and outcomes of CCUD. PMID- 29169452 TI - Robotic Cystectomy with Intracorporeal Urinary Diversion: Review of Current Techniques and Outcomes. AB - This article reviews the current techniques and outcomes of robot-assisted radical cystectomy with totally intracorporeal urinary diversion. Discussion includes techniques for port placement and methods for urinary diversion for neobladder, ileal conduit, and one case of continent cutaneous diversion. The outcomes analyzed include operative time, estimated blood loss, transfusion rate, conversion to open surgery, and early or late postoperative complications. PMID- 29169453 TI - Surgical Complications of Urinary Diversion. AB - Urinary diversion (UD) with an intestinal segment has significant risks of short- and long-term complications. With modern reporting criteria, understanding of the true prevalence and spectrum of these complications has improved. Methods to minimize early postoperative complications include enhanced recovery pathways, restricted intraoperative fluid protocols, and referral to high-volume centers. With long-term follow-up after UD, the risk of complications steadily rises. Late surgical complications include ureterointestinal anastomotic strictures, urolithiasis, and stomal issues. Patients with UDs require close surveillance to monitor for anatomic, infectious, and metabolic complications and surgeons who perform UD should be aware of the risk and timing of postoperative complications. PMID- 29169454 TI - Secondary Tumors After Urinary Diversion. AB - It has been known that urinary diversions juxtaposing the urinary and intestinal tracts lead to increased incidence of secondary malignancies. Although tumorigenesis in ureterosigmoidostomies follows the typical course from adenomas to adenocarcinomas, secondary malignancies arising from isolated intestinal diversions are much more heterogeneous. Research over the last half century has unveiled patterns of incidence and progression, while also uncovering possible mechanisms driving the neoplastic changes. In this review, we summarize the current understanding of these unique tumors, with the hope that the knowledge gained may shed light on the etiologies of other cancers arising from the urinary and intestinal tracts.

However, it is unclear if S. aureus is a cause of atopic dermatitis or a consequence of the abnormal epithelial environment. In this issue of the Journal of Investigative Dermatology, Meylan et al. present evidence from a prospective clinical trial that shows that S. aureus colonization precedes onset of atopic dermatitis in children. These observations suggest that S. aureus may cause atopic dermatitis in some individuals. PMID- 29169459 TI - Production of Neoepitopes by Dynamic Structural Changes on BP180/Type XVII Collagen.

AB - The regulation of site-specific pigmentation in reconstructs used for skin grafting is incompletely understood. Using an engineered skin equivalent model, Klar et al. incorporated adipose-derived mesenchymal cells into skin substitutes and found that adipose-derived mesenchymal cells secreted high levels of transforming growth factor-beta1, which down-regulates melanogenic enzymes such as tyrosinase to decrease melanin synthesis and prevent normal pigmentation of resulting skin grafts.

A persistent goal in biological research is to develop assays that can faithfully capture different types of protein interactions to allow their study. A major step forward in this direction came with a family of methods that delineates spatial proximity of proteins as an indirect measure of protein protein interaction. A variety of enzyme- and DNA ligation-based methods measure protein co-localization in space, capturing novel interactions that were previously too transient or low affinity to be identified. Here we review some of the methods that have been successfully used to measure spatially proximal protein-protein interactions. PMID- 29169466 TI - SnapshotDx Quiz: December 2017.

AB - BACKGROUND: Lifelong oral anticoagulation, either with warfarin or a non-vitamin K antagonist oral anticoagulant (NOAC), is indicated for stroke prevention in most patients with atrial fibrillation (AF). Emerging evidence suggests that NOACs may be associated with better renal outcomes than warfarin. OBJECTIVES: This study aimed to compare 4 oral anticoagulant agents (apixaban, dabigatran, rivaroxaban, and warfarin) for their effects on 4 renal outcomes: >=30% decline in estimated glomerular filtration rate (eGFR), doubling of the serum creatinine level, acute kidney injury (AKI), and kidney failure. METHODS: Using a large U.S. administrative database linked to laboratory results, the authors identified 9,769 patients with nonvalvular AF who started taking an oral anticoagulant agent between October 1, 2010 and April 30, 2016. Inverse probability of treatment weighting was used to balance more than 60 baseline characteristics among patients in the 4 drug cohorts. Cox proportional hazards regression was performed in the weighted population to compare oral anticoagulant agents. RESULTS: The cumulative risk at the end of 2 years for each outcome was 24.4%, 4.0%, 14.8%, and 1.7% for >=30% decline in eGFR, doubling of serum creatinine, AKI, and kidney failure, respectively. When the 3 NOACs were pooled, they were associated with reduced risks of >=30% decline in eGFR (hazard ratio [HR]: 0.77; 95% confidence interval [CI]: 0.66 to 0.89; p < 0.001), doubling of serum creatinine (HR: 0.62; 95% CI: 0.40 to 0.95; p = 0.03), and AKI (HR: 0.68; 95% CI: 0.58 to 0.81; p < 0.001) compared with warfarin. When comparing each NOAC with warfarin, dabigatran was associated with lower risks of >=30% decline in eGFR and AKI; rivaroxaban was associated with lower risks of >=30% decline in eGFR, doubling of serum creatinine, and AKI; however, apixaban did not have a statistically significant relationship with any of the renal outcomes. CONCLUSIONS: Renal function decline is common among patients with AF treated with oral anticoagulant agents. NOACs, particularly dabigatran and rivaroxaban, may be associated with lower risks of adverse renal outcomes than warfarin.

PMID- 29169471 TI - Fondaparinux for Treatment of Heparin-Induced Thrombocytopenia: Too Good to Be True? PMID- 29169470 TI - Use of Fondaparinux Off-Label or Approved Anticoagulants for Management of Heparin-Induced Thrombocytopenia. AB - BACKGROUND: Life-threatening heparin-induced thrombocytopenia (HIT) is treated with the alternative nonheparin anticoagulants argatroban, lepirudin, or danaparoid. Frequently, the pentasaccharide fondaparinux is used off-label. OBJECTIVES: The authors sought to investigate the safety and efficacy of the different anticoagulants for treating HIT. METHODS: In a national, multicenter registry study, hospitalized patients who were diagnosed with HIT, an at least intermediate clinical HIT-risk (4Ts score >=4 points), and received treatment with >=1 dose of the aforementioned anticoagulants were included. Main outcome measures were the incidences of HIT-specific complications (thromboembolic venous/arterial events, amputations, recurrent/persistent thrombocytopenia, skin lesions) and bleedings. RESULTS: Of 195 patients, 46 (23.6%), 4 (2.1%), 61 (31.3%), and 84 (43.1%) had been treated first-line with argatroban, lepirudin, danaparoid, and fondaparinux, respectively. The composite endpoint of HIT specific complications (thromboembolic events, amputation, skin necrosis) occurred in 11.7% of patients treated with approved alternative anticoagulation and in 0.0% of fondaparinux-treated patients. The all-cause in-hospital mortality rates were 14.4% during approved alternative anticoagulation and 0.0% during fondaparinux treatment. Bleeding complications occurred in alternatively anticoagulated patients and in fondaparinux-treated patients in 6.3% and 4.8%, respectively. Post hoc analysis of clinical and laboratory features confirmed "true" HIT in at least 74 of 195 (38.0%) patients; 35 of 74 (47.3%) were treated with fondaparinux. CONCLUSIONS: Fondaparinux is effective and safe in suspected acute HIT; no HIT-specific complications occurred in the fondaparinux-treated patients, even among those with a high clinical HIT probability. Further data from randomized controlled trials are urgently needed because lepirudin was recalled from the market; danaparoid access has been limited and is not approved in the United States; and argatroban is contraindicated in patients with impaired liver function, and activated partial thromboplastin time confounding may interfere with monitoring.

PMID- 29169472 TI - Inhaled Xenon Attenuates Myocardial Damage in Comatose Survivors of Out-of Hospital Cardiac Arrest: The Xe-Hypotheca Trial. AB - BACKGROUND: The authors previously reported that inhaled xenon combined with hypothermia attenuates brain white matter injury in comatose survivors of out-of hospital cardiac arrest (OHCA). OBJECTIVES: A pre-defined secondary objective was to assess the effect of inhaled xenon on myocardial ischemic damage in the same study population. METHODS: A total of 110 comatose patients who had experienced OHCA from a cardiac cause were randomized to receive either inhaled xenon (40% end-tidal concentration) combined with hypothermia (33 degrees C) for 24 h (n = 55; xenon group) or hypothermia treatment alone (n = 55; control group). Troponin T levels were measured at hospital admission, and at 24 h, 48 h, and 72 h post cardiac arrest. All available cases were analyzed for troponin-T release. RESULTS: Troponin-T measurements were available from 54 xenon patients and 54 control patients. The baseline characteristics did not differ significantly between the groups. After adjustments for age, sex, study site, primary coronary percutaneous intervention (PCI), and norepinephrine dose, the mean +/- SD post arrival incremental change of the ln-transformed troponin-T at 72 h was 0.79 +/- 1.54 in the xenon group and 1.56 +/- 1.38 in the control group (adjusted mean difference -0.66; 95% confidence interval: -1.16 to -0.16; p = 0.01). The effect of xenon on the change in the troponin-T values did not differ in patients with or without PCI or in those with a diagnosis of ST-segment elevation myocardial infarction (group by PCI or ST-segment elevation myocardial infarction interaction effect; p = 0.86 and p = 0.71, respectively). CONCLUSIONS: Among comatose survivors of OHCA, in comparison with hypothermia alone, inhaled xenon combined with hypothermia suggested a less severe myocardial injury as demonstrated by the significantly reduced release of troponin-T. PMID- 29169475 TI - Outcomes in Pediatric Dilated Cardiomyopathy: Quo Vadis? PMID- 29169474 TI - Survival Without Cardiac Transplantation Among Children With Dilated Cardiomyopathy. AB - BACKGROUND: Studies of children with dilated cardiomyopathy (DCM) have suggested that improved survival has been primarily due to utilization of heart transplantation. OBJECTIVES: This study sought to determine transplant-free survival for these children over 20 years and identify the clinical characteristics at diagnosis that predicted death. METHODS: Children <18 years of age with some type of DCM enrolled in the Pediatric Cardiomyopathy Registry were divided by year of diagnosis into an early cohort (1990 to 1999) and a late cohort (2000 to 2009). Competing risks and multivariable modeling were used to estimate the cumulative incidence of death, transplant, and echocardiographic normalization by cohort and to identify the factors associated with death. RESULTS: Of 1,953 children, 1,199 were in the early cohort and 754 were in the late cohort. Most children in both cohorts had idiopathic DCM (64% vs. 63%, respectively). Median age (1.6 vs. 1.7 years), left ventricular end-diastolic z scores (+4.2 vs. +4.2), and left ventricular fractional shortening (16% vs. 17%) at diagnosis were similar between cohorts. Although the rates of echocardiographic normalization (30% and 27%) and heart transplantation (24% and 24%) were similar, the death rate was higher in the early cohort than in the late cohort (18% vs. 9%; p = 0.04). Being in the early cohort (hazard ratio: 1.4; 95% confidence interval: 1.04 to 1.9; p = 0.03) independently predicted death. CONCLUSIONS: Children with DCM have improved survival in the more recent era. This appears to be associated with factors other than heart transplantation, which was equally prevalent in both eras.

AB - Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors substantially reduce low-density lipoprotein cholesterol, but it is presently unclear whether they also reduce mortality. The list prices of PCSK9 inhibitors in the United States (>$14,500 per year) are >100* higher than generic statins, and only a small fraction of their higher cost is likely to be recovered by prevention of cardiovascular events. The projected cost effectiveness of PCSK9 inhibitors does not meet generally accepted benchmarks for good value in the United States, but their value would be improved by substantial price reductions. For individual patients, the high out-of-pocket costs of PCSK9 inhibitors may impede access and reduce long-term adherence. The budgetary impact of PCSK9 inhibitors would be very large if all potentially eligible patients were treated, which poses dilemmas for policymakers, payers, and society. PMID- 29169477 TI - CPR Instruction in U.S. High Schools: What Is the State in the Nation? AB - Cardiopulmonary resuscitation (CPR) training in high schools is required by law in the majority of U.S. states. However, laws differ from state to state, and it is unknown how this legislation is being enacted. The authors sent a cross sectional, closed survey to educational superintendents in 32 states with CPR laws in June 2016. The authors subsequently performed direct examination and categorization of CPR legislation in 39 states (several states passed legislation as of September 2017). Survey results indicated differing practices with regard to CPR instruction in areas such as course content (63% perform automated external defibrillator training), instructor (47% used CPR-certified teachers/coaches, 30% used other CPR-certified instructors, 11% used noncertified teachers/coaches), and method (7% followed American Red Cross methods, 55% followed American Heart Association methods). CPR laws differ, although almost all (97%) require hands-on training. Although hands-on practice during CPR instruction in high school is required by law in the majority of U.S. states, there is currently no standardized method of implementation.

PMID- 29169493 TI - Contemporary Arterial Access in the Cardiac Catheterization Laboratory. AB - Obtaining femoral and radial arterial access in the cardiac catheterization laboratory using state-of-the-art techniques is essential to optimize outcomes, patient satisfaction, and procedural efficiency. Although transradial access is increasingly used for coronary angiography and percutaneous coronary intervention, femoral access remains necessary for numerous procedures, many requiring large-bore access, including complex high-risk coronary interventions, structural procedures, and procedures involving mechanical circulatory support. For femoral access, contemporary access techniques should combine the use of fluoroscopy, ultrasound, micropuncture needle, femoral angiography, and vascular closure devices, when feasible. For radial access, ultrasound may reveal important anatomic features and expedite access. Despite randomized controlled trials supporting use of routine ultrasound guidance for femoral and/or radial arterial access, ultrasound remains underused in cardiac catheterization laboratories. This article reviews contemporary techniques to achieve optimal arterial access in the cardiac catheterization laboratory.

AB - OBJECTIVES: This study sought to examine the relationship between access site practice and clinical outcomes in patients requiring percutaneous coronary intervention (PCI) following thrombolysis for ST-segment elevation myocardial infarction (STEMI). BACKGROUND: Transradial access (TRA) is associated with better outcomes in patients requiring PCI for STEMI. A significant proportion of STEMI patients may receive thrombolysis before undergoing PCI in many countries across the world. There are limited data around access site practice and its associated outcomes in this cohort of patients. METHODS: The author used the British Cardiovascular Intervention Society dataset to investigate the outcomes of patients undergoing PCI following thrombolysis between 2007 and 2014. Patients were divided into TRA and transfemoral access groups depending on the access site used. Multiple logistic regression and propensity score matching were used to study the association of access site with in-hospital and long-term mortality, major bleeding, and access site-related complications. RESULTS: A total of 10,209 patients received thrombolysis and PCI during the study time. TRA was used in 48% (n = 4,959) of patients; 3.3% (n = 336) patients died in hospital, 1.6% (n = 165) of patients experienced major bleeding, 4.2% (n = 437) experienced major adverse cardiac events (MACE), and 4.6% (n = 468) experienced 30-day mortality. After multivariate adjustment, TRA was associated with significantly reduced odds of in hospital mortality (odds ratio [OR]: 0.59; 95% confidence interval [CI]: 0.42 to 0.83; p = 0.002), major bleeding (OR: 0.45; 95% CI: 0.31 to 0.66; p < 0.001), MACE (OR: 0.72; 95% CI: 0.55 to 0.94; p = 0.01), and 30-day mortality (OR: 0.72; 95% CI: 0.55 to 0.94; p = 0.01). CONCLUSIONS: TRA is associated with decreased odds of bleeding complications, mortality, and MACE in patients undergoing PCI following thrombolysis and should be preferred access site choice in this cohort of patients.

PMID- 29169496 TI - Transfemoral Approach for Coronary Angiography and Intervention: A Collaboration of International Cardiovascular Societies. AB - OBJECTIVES: The aim of this study was to examine the current practice and use of transfemoral approach (TFA) for coronary angiography and intervention. BACKGROUND: Wide variability exists in TFA techniques for coronary procedures. METHODS: The authors developed a survey instrument that was distributed via e mail lists from professional societies to interventional cardiologists from 88 countries between March and December 2016. RESULTS: Of 987 operators, 18% were femoralists, 38% radialists, 42% both, and 2% neither. Access using femoral pulse palpation alone was preferred by 60% of operators, fluoroscopy guidance by 11%, and a combination of palpation, fluoroscopy, or ultrasound by 27%. Only 11% used micropuncture in >90% of their cases. Performing femoral angiography immediately after access was preferred by 23% and at the end of the procedure by 47%, and not done at all by 31% of operators. Hemostasis by manual compression was preferred by 50%, collagen plug vascular closure device by 31%, and suture-based vascular closure device by 11% of operators. Judkins left and right catheters were preferred for diagnostic angiography of the left (99%) and right (94%) coronary arteries. Extra backup curves (XB or EBU) were most commonly preferred for percutaneous coronary intervention of the left anterior descending (80%) and left circumflex (80%), whereas the Judkins right catheter was preferred for percutaneous coronary intervention of the right coronary artery (86%). CONCLUSIONS: There is significant variability in preferences for femoral access technique. Even though recommended best practices advocate for fluoroscopic and ultrasound guidance, most operators use palpation alone. Femoral angiography is also not consistently used despite guideline recommendations. The lack of adoption of imaging guidance for vascular access deserves further investigation. PMID- 29169499 TI - Time to Redefine Critical Limb Ischemia. PMID- 29169498 TI - Heterogeneity of Ankle-Brachial Indices in Patients Undergoing Revascularization for Critical Limb Ischemia. AB - OBJECTIVES: This study sought to describe the distribution of pre-intervention treated-limb ankle-brachial indices (ABIs) among patients with critical limb ischemia (CLI) undergoing percutaneous vascular intervention (PVI) or surgical revascularization (SR). BACKGROUND: CLI is diagnosed by the presence of rest pain, tissue ulceration, or gangrene due to chronic arterial insufficiency. It is unclear what fraction of patients with suspected CLI have severe peripheral artery disease (PAD) on noninvasive functional testing. METHODS: The study included patients who underwent lower extremity revascularization for CLI in a multicenter registry in Michigan from January 2012 through June 2015. ABIs were classified as normal (ABI: 0.91 to 1.40), mild-moderate (ABI: 0.41 to 0.90), and severe (ABI: <=0.40). Pre- and post-intervention Peripheral Artery Questionnaire summary scores were assessed in a subset of patients. RESULTS: Among 10,756 patients with signs or symptoms of CLI, 9,113 (84.7%) underwent PVI and 1,643 (15.3%) underwent SR. ABIs were recorded in 4,972 (54.6%) PVI and 1,012 (61.6%) SR patients. Patients undergoing PVI had higher ABIs than those undergoing SR, with substantial variation in both groups (PVI: 0.72 +/- 0.29 vs. SR: 0.61 +/- 0.29; p < 0.001). Nearly a quarter of patients with compressible arteries had normal ABIs (24.0%), whereas severe PAD was uncommon (16.5%). A significant improvement in Peripheral Artery Questionnaire scores was noted after intervention across all ABI categories. CONCLUSIONS: Among patients undergoing revascularization for CLI in contemporary practice, the authors found substantial heterogeneity in pre-intervention ABIs. The disconnect between ABI results and clinical diagnosis calls into question the utility of ABIs in this population and suggests the need for standardization of functional PAD testing.

PMID- 29169500 TI - 1-Year Results of a Multicenter Randomized Controlled Trial Comparing Heparin Bonded Endoluminal to Femoropopliteal Bypass. AB - OBJECTIVES: This study sought to compare heparin-bonded endografts with femoropopliteal bypass, including quality of life, using general health and disease-specific questionnaires as well as patency rates. BACKGROUND: Endovascular treatment continues to advance and is gaining acceptance as primary treatment for long occlusive or stenotic lesions in the superficial femoral artery. Heparin-bonded expanded polytetrafluoroethylene endografts have been related to outcomes comparable to bypass surgery, but this has not been tested in a randomized fashion. METHODS: A multicenter randomized-controlled trial was performed comparing femoropopliteal bypass with heparin-bonded expanded polytetrafluoroethylene endografts. Data were analyzed on an intention-to-treat and per-protocol manner. RESULTS: A total of 129 patients were randomized and 125 patients were treated, 63 in the endoluminal and 62 in the surgical group (42 venous, 20 prosthetic). Enrollment was terminated before reaching the predefined target number for patency. Baseline characteristics and anatomical data were similar. Patients were treated for critical limb ischemia in 38.1% and 32.2% in the endoluminal and surgical arms, respectively. Mean lesion length was 23 cm in both groups and lesions were largely TransAtlantic Inter-Society Consensus II D. Hospitalization time and 30-day morbidity were significantly lower in the endoluminal group, without differences in serious adverse events (n = 5 each; surgical: 4 venous and 1 polytetrafluoroethylene bypass). There were no significant differences in Rutherford category between groups at any time point. At 30 days the endoluminal group showed a greater improvement in quality-of-life scores. At 1 year, these differences had largely disappeared and no differences in primary (endoluminal: 64.8%; surgical: 63.6%), assisted primary (endoluminal: 78.1%; surgical: 79.8%), secondary patency (endoluminal: 85.9%; surgical: 83.3%), and target vessel revascularization (endoluminal: 72.1%; surgical: 71.0%) were observed. Limb salvage rate was 100% in both groups. CONCLUSIONS: Heparin-bonded endoluminal bypass for long segment lesions shows promising results (less morbidity, faster recovery, and improvement in quality of life with indistinguishable patency rates at 1 year) compared with surgical bypass. Long term results have to be awaited. PMID- 29169503 TI - Reply: Repeated Intracoronary Imaging in Spontaneous Coronary Artery Dissection: Weighing Benefits and Risks. PMID- 29169502 TI - Re-Evaluating the Safety of Drug-Eluting Stents in Cancer Patients. AB - Evidence increasingly shows that cancer and coronary artery disease are interlinked through common risk factors, co-occurrence in an aging population, and through the deleterious effects of cancer treatment on cardiovascular health. Many of the clinical risk factors for cancer, such as diabetes, smoking, and chronic inflammatory state, are also risk factors for coronary artery disease and for stent restenosis and thrombosis. The current generations of drug-eluting stents have been proven to reduce the risk of restenosis and stent thrombosis as compared with bare-metal stents. However, because of the perceived need for shorter course of dual antiplatelet treatment, operators often prefer bare-metal stents in patients with cancer out of concern for increased bleeding risk and expectant need for cancer-directed surgery. The current evidence with newer generation stent technology demonstrates the feasibility of shorter duration of dual antiplatelet treatment, without increasing the risk of stent thrombosis and bleeding, while maintaining improved efficacy compared with bare-metal stents. Cardiovascular disease in patients with cancer is complex, and treatment needs to be individualized. Refraining from the use of drug-eluting stents altogether in this rapidly expanding cohort may lead to higher major adverse cardiovascular events, which can thwart the effectiveness of advances in both cancer and cardiovascular therapeutics. Considering the developing evidence thus far, perhaps it is time to rethink the choice of stent in patients with cancer who undergo percutaneous coronary intervention.

PMID- 29169511 TI - Longitudinal and cross-sectional assessment of quality of life in surgically treated advanced (T4) cancer of the buccal mucosa. AB - OBJECTIVE: Quality of life (QOL) has become an important aspect of today's health care management. This study performed longitudinal assessment of QOL in patients with advanced cancers of the buccal mucosa (T4). We compared the QOL between patients who received adjuvant chemoradiation therapy (CTRT) and that of patients who received radiation therapy alone and assessed whether baseline QOL can predict disease recurrence. STUDY DESIGN: This was a prospective study of 225 patients with T4 buccal mucosal cancer. Health-related QOL was assessed at baseline and at 3, 6, 9, and 12 months after completion of treatment by means of the European Organization for Research and Treatment of Cancer Core QOL Questionnaire and the HN35 questionnaire. RESULTS: There was persistent improvement in global QOL and pain. Emotional functioning improved at 12 months. Most of the head and neck-specific symptoms deteriorated at 3 months, with subsequent improvement at 12 months except in swallowing, senses, speech, social eating, social contact, and sexuality. Patients who received adjuvant CTRT had poorer QOL. Poorer baseline global QOL (P = .049), dyspnea (P = .04), appetite loss (P = .015), and weight loss (P = .08) may predict recurrence. CONCLUSIONS: Although there is an improvement in global QOL and pain, most of the head and neck-specific symptoms worsened in the immediate postoperative period. Adjuvant CTRT has a persistent effect on specific domains compared with adjuvant radiation therapy alone. Poor baseline QOL scores are associated with a higher risk of recurrence. PMID- 29169512 TI - Radiation-related caries assessment through the International Caries Detection and Assessment System and the Post-Radiation Dental Index. AB - OBJECTIVE: Although radiation-related caries (RRC) are a well-known toxicity of head and neck radiotherapy, a clinical classification system for RRC has not yet been clinically validated. Therefore, the aim of this study was to assess whether the International Caries Detection and Assessment System (ICDAS) and the Post Radiation Dental Index (PRDI) were viable methods for the assessment of RRC. STUDY DESIGN: Clinicopathologic data and intraoral digital photographs of 60 patients (833 teeth) affected by RRC were assessed and classified according to the ICDAS and PRDI criteria. RESULTS: A total of 814 (97.7%) teeth presented RRC lesions ranging from early stage to complete tooth destruction. Mean scores for the whole sample were 5 for ICDAS and 3 for PRDI, indicating that RRC were diagnosed predominately in late stages. ICDAS and PRDI criteria underestimate the clinical expressivity of RRC by not including the whole qualitative clinical spectrum of RRC, such as enamel cracks, delamination, dental crown amputation, surface color alterations, and atypical lesions topography (incisal/cuspal caries). CONCLUSIONS: ICDAS and PRDI may not be considered viable for the assessment of RRC. The development of a specific clinical classification system is urgently needed to help clinicians recognize the peculiar patterns of RRC, particularly in incipient cases.

PMID- 29169513 TI - The reliability of different methods of manual volumetric segmentation of pharyngeal and sinonasal subregions. AB - OBJECTIVES: The purpose of the study was to test the intra and interobserver reliability of manual volumetric segmentation of pharyngeal and sinonasal airway subregions. STUDY DESIGN: Cone beam computed tomography data of 15 patients were collected from an orthodontic clinical database. Two experienced orthodontists independently performed manual segmentation of the airway subregions. Four performance measures were considered to test intra and interobserver reliability of manual segmentation: (1) volume correlation, (2) mean slice correlation, (3) percentage of volume difference, and (4) percentage of nonoverlapping voxels. RESULTS: Intra and interobserver reliability was observed to be greater than 0.96 for the entire pharyngeal and sinonasal airway sinus subregions by both observers using the volume correlation method. Mean slice correlation was found to be greater than 0.84, showing the existence of nonoverlapping voxels. Therefore, the percentage of nonoverlapping voxels was used as a reliability measure and was found to be less than 20% for both intra and interobserver markings. CONCLUSIONS: The mean slice correlation and percentage of nonoverlapping voxels were the most reliable performance measures of segmentation correctness. Volume correlation and the percentage of volume difference were observed to be the most reliable performance measures for volume correctness.

AB - PURPOSE: To describe time trends and current patterns in sexual practices with opposite-sex partners among men and women aged 16-24 years in Britain. METHODS: Complex survey analyses of cross-sectional probability survey data from three British National Surveys of Sexual Attitudes and Lifestyles (Natsal), conducted approximately decennially 1990-2012, involving interviews with 45,199 people in total. RESULTS: Birth cohort analysis showed a decline in the median age at first sexual experience and first intercourse since the midtwentieth century and a narrowing of the interval between these events. Comparison of data from Natsals 1, 2, and 3 showed increases in the prevalence of ever experience of oral and anal sex among 16- to 24-year-olds, which were more marked among older respondents in this age group between Natsals 1 and 2, and among younger respondents between Natsals 2 and 3. Among the sexually active, vaginal and oral sex remained the most common combination of practices reported in the past year. The proportion reporting a past-year repertoire of vaginal, oral, and anal sex rose from approximately one in 10 in 1990-1991 to approximately one in four men and one in five women in 2010-2012. In the latest survey, heterosexual experience of practices was positively associated with bisexual attraction among women. CONCLUSIONS: Recent decades have seen an earlier age at initiation of partnered sexual experiences and increased diversity in heterosexual practices among young people. Keeping pace with trends in sexual practices is necessary to safeguard young people's health and to support them in increasing their sexual well-being.

Even though existing research using cross-sectional studies has demonstrated that part of these differences can be attributed to compositional differences in human capital, household conditions and gender attitudes, residual 'ethnic effects' typically remain. To further our understanding of women's labour market behaviour across ethnic groups, we use a large-scale longitudinal study and apply a dynamic perspective to examine how far relevant life-course events in addition to individual characteristics, gender attitudes and religiosity contribute to the explanation of ethnic differences in women's labour force entries and exits in the UK. Our findings show that, adjusting for all these factors, Indian and Caribbean women do not differ from White majority women in their labour force entry and exit probabilities but that Pakistani and Bangladeshi women are less likely to enter and more likely to exit the labour market, whereas Black African women have higher entry rates. We also find that relations between life-course events and labour market transitions differ by ethnic group. Most notably, Pakistani and Bangladeshi women's labour market transitions are less sensitive to child-bearing and Caribbean women's transitions less sensitive to partnership changes than other women's. PMID- 29169531 TI - For everything a season? A month-by-month analysis of social network resources in later life. AB - It is widely acknowledged that informal social ties provide older persons with many resources that serve to protect and improve their levels of health and well being. Most studies on this topic, however, ignore the month or season of the year during which data was accumulated. This study proposes two hypotheses to explain seniors' social network resources over the calendar year: the "fluctuation hypothesis", which proposes that seasonal variation, in the form of weather fluctuations, institutional calendars, and holidays, might influence the social lives and resources of older persons, and the "network stability" perspective, which, informed by tenets of convoy theory and socioemotional selectivity theory, emphasizes the increasing importance of close network ties as individuals age and the stability of these ties. Using two waves (2005-2006 and 2010-2011) of the National Social Life, Health, and Aging Project (NSHAP), a nationally representative sample of community-dwelling older adults aged 57-85 in the United States, we examine a diverse set of nine social connectedness outcomes. Results, overall, support the network stability perspective, as the only social connectedness outcome found to significantly vary by month of year was average closeness with network members. We conclude by suggesting some methodological considerations for survey research and by noting how these findings complement the growing literature on inter-year fluctuation in social networks and social support. Changes in older adults' networks, while frequently observable over the course of years, do not seem to be seasonally patterned. PMID- 29169532 TI - Barrios, ghettos, and residential racial composition: Examining the racial makeup of neighborhood profiles and their relationship to self-rated health. AB - Racial/ethnic disparities in self-rated health persist and according to the social determinants of health framework, may be partially explained by residential context. The relationship between neighborhood factors and self-rated health has been examined in isolation but a more holistic approach is needed to understand how these factors may cluster together and how these neighborhood typologies relate to health. To address this gap, we conducted a latent profile analysis using data from the Chicago Community Adult Health Study (CCAHS; N = 2969 respondents in 342 neighborhood clusters) to identify neighborhood profiles, examined differences in neighborhood characteristics among the identified typologies and tested their relationship to self-rated health. Results indicated four distinct classes of neighborhoods that vary significantly on most neighborhood-level social determinants of health and can be defined by racial/ethnic composition and class. Residents in Hispanic, majority black disadvantaged, and majority black non-poor neighborhoods all had significantly poorer self-rated health when compared to majority white neighborhoods. The difference between black non-poor and white neighborhoods in self-rated health was not significant when controlling for individual race/ethnicity. The results indicate that neighborhood factors do cluster by race and class of the neighborhood and that this clustering is related to poorer self-rated health. PMID- 29169533 TI - Leaving late: Understanding the extent and predictors of college late departure. AB - Research on college dropout has largely addressed early exit from school, even though a large share of students who do not earn degrees leave after their second year. In this paper, we offer new evidence on the scope of college late departure. Using administrative data from Florida and Ohio, we conduct an event history analysis of the dropout process as a function of credit attainment. Our results indicate that late departure is widespread, particularly at two- and open admission four-year institutions. We estimate that 14 percent of all entrants to college and one-third of all dropouts completed at least three-quarters of the credits that are typically required to graduate before leaving without a degree. Our results also indicate that the probability of departure spikes as students near the finish line. Amidst considerable policy attention towards improving student outcomes in college, our findings point to promising new avenues for intervention to increase postsecondary attainment. PMID- 29169534 TI - Race, ageism and the slide from privileged occupations. AB - The sociological literature on workplace inequality has been relatively clear regarding racial disparities and ongoing vulnerabilities to contemporary structural and employer biases. We still know little, however, about the consequences of age and ageism for minority workers and susceptibilities to downward mobility. Coupling insights regarding race with recent work on employment-based age discrimination, we interrogate in this article African Americans and Whites, aged 55 and older, and the extent to which they experience job loss across time. Our analyses, beyond controlling for key background attributes, distinguish and disaggregate patterns for higher and lower level status managers and professionals and for men and women. Results, derived from data from the Panel Study of Income Dynamics, reveal unique and significant inequalities. Relative to their White and gender specific counterparts, older African American men and women experience notably higher rates of downward mobility-downward mobility that is not explained by conventional explanations (i.e., human capital credentials, job/labor market characteristics, etc.). Such inequalities are especially pronounced among men and for those initially occupying higher status white-collar managerial and professional jobs compared to technical/skilled professional and blue-collar "first line" supervisors. We tie our results to contemporary concerns regarding ageism in the workplace as well as minority vulnerability. We also suggest an ageism-centered corrective to existing race and labor market scholarship. PMID- 29169535 TI - One flag, two rallies: Mechanisms of public opinion in Israel during the 2014 Gaza war. AB - In Israel, public reaction to the 2014 Gaza war included massive support for the military operation and a sharp increase in the popularity of Prime Minister Netanyahu. To understand what caused these "rally-round-the-flag" (RRTF) effects, panel data were collected from a representative sample of the Jewish majority in Israel during and after the war. The article integrate empirical and theoretical arguments from public opinion studies, and from social and political psychology, to contextualize and guide the analysis. The results reveal that perceived threat to collective security produced two simultaneous rally outcomes through distinct processes: First, increased identification with the ethno-national Jewish group led to a rally behind Israel's prime minister. Second, anger toward Hamas and sentiment of national superiority, which was activated by increased ethno national identification, produced a rally behind the military operation. In addition to explaining its specific empirical case, this study makes three broader contributions. First, it extends the investigation of the RRTF phenomenon in wartime beyond the popularity of the head of the state (the focus of most previous studies) by also examining levels of support for the use of military power. Second, it reveals some of the mechanisms through which distinct elements of popular nationalism mediate the relationship between war events and heterogeneous rally effects. Third, this study shows that the mechanisms that have been detected in studies of individual attitudes and behavior in small groups under conditions of perceived threat or competition can help explain the behavior of these individuals as members of larger, imagined national communities during war.

PMID- 29169536 TI - Countervailing contact: Community ethnic diversity, anti-immigrant attitudes and mediating pathways of positive and negative inter-ethnic contact in European societies. AB - Inter-ethnic contact has long been held as a key means of ameliorating possible inter-group tensions and facilitating the integration of increasing immigrant populations into society. However, our understanding of the role of contact in this relationship may be limited due to the omission of contact-valence; that is, whether contact is experienced positively or negatively. This paper integrates the concept of contact-valence into the question of how increasing community diversity affects attitudes towards immigrants via inter-group contact, across Europe. We posit the existence of dual, mediating pathways of both positive and negative inter-group contact. Applying generalized structural equation models to data from the 2014 European Social Survey, we find that living in more diverse communities increases the frequency of positive inter-group contact but also negative inter-group contact. While the former is positively associated with inter-group attitudes the latter is negatively associated. Testing demonstrates that diversity exerts countervailing positive and negative indirect-effects on attitudes towards immigrants via processes of inter-group contact. Furthermore, while the net-effect of diversity on attitudes via contact is positive, attitudes amongst those experiencing more frequent negative contact become progressively worse. Increasing diversity therefore leads to a polarisation in attitudes towards immigration as a result of, and not due to a lack of, inter-group contact. PMID- 29169539 TI - Invited commentary.

AB - OBJECTIVE: The objective of this study was to assess the reduction in quality of life (QoL) caused by the persistence of primary plantar hyperhidrosis (PPH) symptoms and the level of satisfaction in PPH patients after retroperitoneoscopic lumbar sympathectomy (RLS). The efficacy, safety, and procedure of bilateral RLS in both sexes are also described in this study. METHODS: This is a longitudinal study of consecutive patients who sought specific treatment from a private practitioner for severe PPH as classified on the Hyperhidrosis Disease Severity Scale (HDSS) from October 2005 to October 2014. The patients were asked to report the symptoms of PPH experienced in the immediate preoperative period and to complete a standardized QoL questionnaire developed by de Campos at least 12 months after RLS. Disease outcomes, recurrence of symptoms, and any adverse effects of surgery were evaluated after 30 days and at least 12 months after RLS. RESULTS: Lumbar sympathectomy was performed 116 times in 58 patients; 30 days after surgery, PPH was resolved in all patients. Three patients (5.2%) reported transient thigh neuralgia, and 19 (32.7%) reported transient paresthesia in the lower limbs. There were no reports of retrograde ejaculation. At a minimum of 12 months after RLS, 49 of the 58 patients had fully and correctly answered the follow-up questionnaire and noted a mild (HDSS 2) to moderate (HDSS 3) increase in pre-existing compensatory sweating. One patient had a PPH relapse within 6 months. Improvement in QoL due to the resolution of PPH was reported in 98% of the 49 patients. None of the operations necessitated a change in the laparotomy approach, and none of the patients died. CONCLUSIONS: RLS is safe and effective for the treatment of severe PPH in both sexes. There were no reports of retrograde ejaculation after resection of L3 and L4 ganglia. There was a mild to moderate increase in compensatory sweating in about half of the patients, but without any regret or dissatisfaction for having undergone the surgery because of a significant improvement in QoL.

PMID- 29169544 TI - Systematic review and meta-analysis of duplex ultrasound surveillance for infrainguinal vein bypass grafts. AB - OBJECTIVE: Duplex ultrasound (DUS) surveillance of infrainguinal vein bypass grafts is widely practiced, but the evidence of its effectiveness compared with other methods of surveillance remains unclear. METHODS: Following an a priori protocol developed by the guidelines committee from the Society for Vascular Surgery, this systematic review and meta-analysis included randomized and nonrandomized comparative studies that enrolled patients who underwent infrainguinal arterial reconstruction and received DUS surveillance for follow-up compared with any other method of surveillance. The search included MEDLINE, Embase, Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews, Cumulative Index to Nursing and Allied Health Literature, and Scopus through November 2016. Outcomes of interest included all-cause mortality, limb viability, and graft patency reports. Meta-analysis was performed using the random-effects model. RESULTS: We included 15 studies. Compared with ankle brachial index and clinical examination, DUS surveillance was not associated with a significant change in primary, secondary, or assisted primary patency or mortality. DUS surveillance was associated with a nonstatistically significant reduction in amputation rate (odds ratio, 0.70 [95% confidence interval, 0.23 2.13]). The quality of evidence was low because of imprecision (small number of events and wide confidence intervals) and high risk of bias in the primary literature. CONCLUSIONS: A recommendation for routine DUS surveillance of infrainguinal vein grafts remains dependent on low-quality evidence. Considering that DUS offers the opportunity of early intervention and because of its noninvasive nature and low cost, vascular surgeons may incorporate DUS as they individualize the follow-up of lower extremity vein grafts. PMID- 29169545 TI - An evaluation of the availability, accessibility, and quality of online content of vascular surgery training program websites for residency and fellowship applicants. AB - BACKGROUND: Vascular surgery residency and fellowship applicants commonly seek information about programs from the Internet. Lack of an effective web presence curtails the ability of programs to attract applicants, and in turn applicants may be unable to ascertain which programs are the best fit for their career aspirations. This study was designed to evaluate the presence, accessibility, comprehensiveness, and quality of vascular surgery training websites (VSTW). METHODS: A list of accredited vascular surgery training programs (integrated residencies and fellowships) was obtained from four databases for vascular surgery education: the Accreditation Council for Graduate Medical Education, Electronic Residency Application Service, Fellowship and Residency Electronic Interactive Database, and Society for Vascular Surgery. Programs participating in the 2016 National Resident Matching Program were eligible for study inclusion. Accessibility of VSTW was determined by surveying the Accreditation Council for Graduate Medical Education, Electronic Residency Application Service, and Fellowship and Residency Electronic Interactive Database for the total number of programs listed and for the presence or absence of website links. VSTW were analyzed for the availability of recruitment and education content items. The quality of VSTW was determined as a composite of four dimensions: content, design, organization, and user friendliness. Percent agreements and kappa statistics were calculated for inter-rater reliability. RESULTS: Eighty-nine of the 94 fellowship (95%) and 45 of the 48 integrated residencies (94%) programs participating in the 2016 Match had a VSTW. For program recruitment, evaluators found an average of 12 of 32 content items (35.0%) for fellowship programs and an average of 12 of 32 (37%) for integrated residencies. Only 47.1% of fellowship programs (53% integrated residencies) specified the number of positions available for the 2016 Match, 20% (13% integrated residencies) indicated alumni career placement, 34% (38% integrated residencies) supplied interview dates, and merely 17% (18% integrated residencies) detailed the selection process. For program education, fellowship websites provided an average of 5.1 of 15 content items (34.0%), and integrated residency websites provided 5 of 14 items (34%). Of the fellowship programs, 66% (84.4% integrated residencies) provided a rotation schedule, 65% (56% integrated residencies) detailed operative experiences, 38% (38% integrated residencies) posted conference schedules, and just 16% (28.9% integrated residencies) included simulation training. CONCLUSIONS: The web presence of vascular surgery training programs lacks sufficient accessibility, content, organization, design, and user friendliness to allow applicants to access information that informs them sufficiently. There are opportunities to more effectively use VSTW for the benefit of training programs and prospective applicants. PMID- 29169546 TI - Telehealth electronic monitoring to reduce postdischarge complications and surgical site infections after arterial revascularization with groin incision. AB - It is intuitive that postdischarge surgical complications are associated with increased patient dissatisfaction, and are directly associated with an increase in medical expenditures. It is also easy to make the connection that many post hospital discharge surgical complications, including surgical site infections (SSIs), could be influenced or exacerbated by patient comorbidities. The authors of a recent study reported that female gender, obesity, diabetes, smoking, hypertension, coronary artery disease, critical limb ischemia, chronic obstructive pulmonary disease, dyspnea, and neurologic disease were significant predictors of SSIs after vascular reconstruction was performed. The main concern for optimal patient care, especially in geographically isolated areas of West Virginia, is to have early, expeditious, and prompt diagnosis of complications and SSI. This adjunct to existing approaches could lead to improved outcomes and patient satisfaction, minimizing third-party interventions and decreasing the total cost of care. It seems reasonable to believe that monitoring using telehealth technology and managing the general health care of patients after a hospital vascular intervention will improve overall health and reduce 30-day readmissions and SSIs.

AB - General paralysis is a neurological symptom of tertiary syphilis that was first identified in asylums as paralytic madness. The enlightened discussion of 60 clinicopathological cases provided by Louis Florentin Calmeil in his 1826 treatise greatly improved our knowledge of general paralysis. However, Calmeil was unable to relate this symptom to syphilis, although the latter was quite widespread at that time. Following a detailed reanalysis of Calmeil's observations with special attention to his clinical and demographic data, we conclude that this eminent clinician was unable to define the cause of general paralysis because his early 19th century mind was still under the influence of traditional knowledge and moral prejudices. For Calmeil, general paralysis belonged entirely to the realm of psychiatry. PMID- 29169564 TI - The Ninth 2016 International London Cough Symposium. PMID- 29169565 TI - Septic systems contribute to nutrient pollution and harmful algal blooms in the St. Lucie Estuary, Southeast Florida, USA. AB - Nutrient enrichment is a significant global-scale driver of change in coastal waters, contributing to an array of problems in coastal ecosystems. The St. Lucie Estuary (SLE) in southeast Florida has received national attention as a result of its poor water quality (elevated nutrient concentrations and fecal bacteria counts), recurring toxic Microcystis aeruginosa blooms, and its proximity to the northern boundary of tropical coral species in the United States. The SLE has an artificially large watershed comprised of a network of drainage canals, one of which (C-44) is used to lower the water level in Lake Okeechobee. Public attention has primarily been directed at nutrient inputs originating from the lake, but recent concern over the importance of local watershed impacts prompted a one-year watershed study designed to investigate the interactions between on site sewage treatment and disposal systems (OSTDS or septic systems), groundwaters, and surface waters in the SLE and nearshore reefs. Results provided multiple lines of evidence of OSTDS contamination of the SLE and its watershed: 1) dissolved nutrients in groundwaters and surface waters were most concentrated adjacent to two older (pre-1978) residential communities and the primary canals, and 2) sucralose was present in groundwater at residential sites (up to 32.0MUg/L) and adjacent surface waters (up to 5.5MUg/L), and 3) delta15N values in surface water (+7.5 o/oo), macroalgae (+4.4 o/oo) and phytoplankton (+5.0 o/oo) were within the published range (>+3 o/oo) for sewage N and similar to values in OSTDS-contaminated groundwaters. Measured delta15N values in M. aeruginosa became increasingly enriched during transport from the C-44 canal (~5.8 o/oo) into the mid-estuary (~8.0 o/oo), indicating uptake and growth on sewage N sources within the urbanized estuary. Consequently, there is a need to reduce N and P loading, as well as fecal loading, from the SLE watershed via septic-to-sewer conversion projects and to minimize the frequency and intensity of the releases from Lake Okeechobee to the SLE via additional water storage north of the lake. These enhancements would improve water quality in both the SLE and Lake Okeechobee, reduce the occurrence of toxic harmful algal blooms in the linked systems, and improve overall ecosystem health in the SLE and downstream reefs. PMID- 29169566 TI - A multilevel trait-based approach to the ecological performance of Microcystis aeruginosa complex from headwaters to the ocean. AB - The Microcystis aeruginosa complex (MAC) clusters cosmopolitan and conspicuous harmful bloom-forming cyanobacteria able to produce cyanotoxins. It is hypothesized that low temperatures and brackish salinities are the main barriers to MAC proliferation. Here, patterns at multiple levels of organization irrespective of taxonomic identity (i.e. a trait-based approach) were analyzed. MAC responses from the intracellular (e.g. respiratory activity) to the ecosystem level (e.g. blooms) were evaluated in wide environmental gradients. Experimental results on buoyancy and respiratory activity in response to increased salinity (0 35) and a literature review of maximum growth rates under different temperatures and salinities were combined with field sampling from headwaters (800km upstream) to the marine end of the Rio de la Plata estuary (Uruguay-South America). Salinity and temperature were the major variables affecting MAC responses. Experimentally, freshwater MAC cells remained active for 24h in brackish waters (salinity=15) while colonies increased their flotation velocity. At the population level, maximum growth rate decreased with salinity and presented a unimodal exponential response with temperature, showing an optimum at 27.5 degrees C and a rapid decrease thereafter. At the community and ecosystem levels, MAC occurred from fresh to marine waters (salinity 30) with a sustained relative increase of large mucilaginous colonies biovolume with respect to individual cells. Similarly, total biomass and, specific and morphological richness decreased with salinity while blooms were only detected in freshwater both at high (33 degrees C) and low (11 degrees C) temperatures. In brackish waters, large mucilaginous colonies presented advantages under osmotic restrictive conditions. These traits values have also been associated with higher toxicity potential. This suggest salinity or low temperatures would not represent effective barriers for the survival and transport of potentially toxic MAC under likely near future scenarios of increasing human impacts (i.e. eutrophication, dam construction and climate change). PMID- 29169567 TI - Sandwich hybridization probes for the detection of Pseudo-nitzschia (Bacillariophyceae) species: An update to existing probes and a description of new probes. AB - New sandwich hybridization assay (SHA) probes for detecting Pseudo-nitzschia species (P. arenysensis, P. fraudulenta, P. hasleana, P. pungens) are presented, along with updated cross-reactivity information on historical probes (SHA and FISH; fluorescence in situ hybridization) targeting P. australis and P. multiseries. Pseudo-nitzschia species are a cosmopolitan group of diatoms that produce varying levels of domoic acid (DA), a neurotoxin that can accumulate in finfish and shellfish and transfer throughout the food web. Consumption of infected food sources can lead to illness in humans (amnesic shellfish poisoning; ASP) and marine wildlife (domoic acid poisoning; DAP). The threat of human illness, along with economic loss from fishery closures has resulted in the implementation of monitoring protocols and intensive ecological studies. SHA probes have been instrumental in some of these efforts, as the technique performs well in complex heterogeneous sample matrices and has been adapted to benchtop and deployable (Environmental Sample Processor) platforms. The expanded probe set will enhance future efforts towards understanding spatial, temporal and successional patterns in species during bloom and non-bloom periods. PMID- 29169568 TI - Life-history stages of natural bloom populations and the bloom dynamics of a tropical Asian ribotype of Alexandrium minutum. AB - In 2015, a remarkably high density bloom of Alexandrium minutum occurred in Sungai Geting, a semi-enclosed lagoon situated in the northeast of Peninsular Malaysia, causing severe discoloration and contaminated the benthic clams (Polymesoda). Plankton and water samples were collected to investigate the mechanisms of bloom development of this toxic species. Analysis of bloom samples using flow cytometry indicated that the bloom was initiated by the process of active excystment, as planomycetes (>4C cells) were observed in the early stage of the bloom. Increase in planozygotes (2C cells) was evident during the middle stage of the bloom, coinciding with an abrupt decrease in salinity and increase of temperature. The bloom was sustained through the combination of binary division of vegetative cells, division of planozygotes, and cyst germination through continuous excystment. Nutrient depletion followed by precipitation subsequently caused the bloom to terminate. This study provides the first continuous record of in situ life-cycle stages of a natural bloom population of A. minutum through a complete bloom cycle. The event has provided a fundamental understanding of the pelagic life-cycle stages of this tropical dinoflagellate, and demonstrated a unique bloom development characteristic shared among toxic Alexandrium species in coastal embayments. PMID- 29169569 TI - Effects of modified clay on the physiological and photosynthetic activities of Amphidinium carterae Hulburt. AB - Among the strategies for treating harmful algal blooms, flocculation using modified clay (MC) has been widely applied in the field. This paper studied the mitigation of MC on Amphidinium carterae Hulburt, finding that MC could not only effectively remove A. carterae, but also affect the physiological activities of the residual algae and inhibit their normal growth. The superoxide dismutase (SOD) activity, catalase (CAT) activity and malondialdehyde (MDA) content of the residual algae significantly increased compared with the control, indicating that MC stimulated the accumulation of reactive oxygen species (ROS) in algal cells. In addition, the cell density was significantly correlated with the SOD activity, CAT activity and MDA content in the experiment groups, suggesting that intracellular ROS might be the main internal factor inhibiting cell growth. To reveal the mechanism of ROS generation, this paper further evaluated the effect of MC on photosynthesis in the residual microalgae, and found that compared with the control the absorption flux per photosystem II (PSII) reaction center (ABS/RC), the trapping flux per RC (TR0/RC) and the electron transport flux per RC (ET0/RC) increased, while the TR0/ABS and ET0/ABS decreased after adding 0.10g/L and 0.25g/L MC. These findings indicate that the MC led to an imbalance between photosynthetic light absorption and energy utilization and that the partial RCs became non-primary quinone electron acceptor (QA)-RCs, further inducing the over-excitation of the active RCs. And MC caused the suppression of the electron transport chain (ETC): the ETC from the QA to the secondary quinone electron acceptor (QB) was blocked and the size of plastoquinone pool decreased, which could induce the over-reduction of PSII. The over-excitation of PSII and the damaged ETC likely induce the generation of ROS during photosynthesis. Thus, MC likely induced the accumulation of intracellular ROS due to photosynthesis inhibition, consequently hindering the growth of the residual algae. PMID- 29169571 TI - Differences in the photoacclimation and photoprotection exhibited by two species of the ciguatera causing dinoflagellate genus, Gambierdiscus. AB - In culture, Gambierdiscus spp. have been shown to prefer irradiances that are relatively low (<=250MUmol photonsm-2s-1) versus those to which they are frequently exposed to in their natural environment (>500MUmol photonsm-2s-1). Although several behavioral strategies for coping with such irradiances have been suggested, it is unclear as to how these dinoflagellates do so on a physiological level. More specifically, how do long term exposures (30days) affect cell size and cellular chlorophyll content, and what is the photosynthetic response to short term, high irradiance exposures (up to 1464MUmol photonsm-2s-1)? The results of this study reveal that cell size and chlorophyll content exhibited by G. carolinianus increased with acclimation to increasing photon flux density. Additionally, both G. carolinianus and G. silvae exhibited reduced photosynthetic efficiency when acclimated to increased photon flux density. Photosynthetic yield exhibited by G. silvae was greater than that for G. carolinianus across all acclimation irradiances. Although such differences were evident, both G. carolinianus and G. silvae appear to have adequate biochemical mechanisms to withstand exposure to irradiances exceeding 250MUmol photonsm-2s-1 for at least short periods of time following acclimation to irradiances of up to 150MUmol photonsm-2s-1. PMID- 29169570 TI - Morphology and phylogeny of Prorocentrum caipirignum sp. nov. (Dinophyceae), a new tropical toxic benthic dinoflagellate. AB - A new species of toxic benthic dinoflagellate is described based on laboratory cultures isolated from two locations from Brazil, Rio de Janeiro and Bahia. The morphology was studied with SEM and LM. Cells are elliptical in right thecal view and flat. They are 37-44MUm long and 29-36MUm wide. The right thecal plate has a V shaped indentation where six platelets can be identified. The thecal surface of both thecal plates is smooth and has round or kidney shaped and uniformly distributed pores except in the central area of the cell, and a line of marginal pores. Some cells present an elongated depression on the central area of the apical part of the right thecal plate. Prorocentrum caipirignum is similar to Prorocentrum lima in its morphology, but can be differentiated by the general cell shape, being elliptical while P. lima is ovoid. In the phylogenetic trees based on ITS and LSU rDNA sequences, the P. caipirignum clade appears close to the clades of P. lima and Prorocentrum hoffmannianum. The Brazilian strains of P. caipirignum formed a clade with strains from Cuba, Hainan Island and Malaysia and it is therefore likely that this new species has a broad tropical distribution. Prorocentrum caipirignum is a toxic species that produces okadaic acid and the fast acting toxin prorocentrolide. PMID- 29169572 TI - Opportunistic salpingectomy in women undergoing hysterectomy: Results from the HYSTUB randomised controlled trial. AB - OBJECTIVE: To evaluate whether opportunistic salpingectomy in premenopausal women undergoing hysterectomy for benign indications is both hormonally and surgically safe, compared with hysterectomy without salpingectomy. STUDY DESIGN: In this multicentre randomised controlled trial, women were randomised to undergo either hysterectomy with opportunistic bilateral salpingectomy (intervention group) or standard hysterectomy with preservation of the Fallopian tubes (control group). MAIN OUTCOME MEASURES: The primary outcome was the difference in serum anti Mullerian hormone concentration (DeltaAMH), measured pre-surgery and 6 months post-surgery. Secondary outcomes were surgical outcomes and duration of hospital stay. The sample size was powered at 50 participants per group (n=100) to compare DeltaAMH after hysterectomy with salpingectomy to DeltaAMH after standard hysterectomy. RESULTS: Between March 2013 and December 2016, 104 women, aged 30 55 years, were randomly allocated to hysterectomy with opportunistic bilateral salpingectomy (n=52) or standard hysterectomy (n=52). The baseline characteristics did not differ between the two groups. The median DeltaAMH was 0.14pmol/L (IQR -1.47-0.95) in the intervention group and 0.00pmol/L (IQR -1.05 0.80) in the control group (p=0.49). The addition of salpingectomy did not impair surgical results and it did not affect duration of hospital stay. CONCLUSION: Addition of opportunistic bilateral salpingectomy during hysterectomy did not result in a larger effect on ovarian reserve when compared with hysterectomy alone, neither did it affect surgical outcomes. Therefore, opportunistic salpingectomy seems to be a safe procedure in premenopausal women undergoing hysterectomy for benign gynaecological conditions. PMID- 29169573 TI - Choosing a medication brand: Excipients, food intolerance and prescribing in older people. AB - Multiple brands of the same active ingredient may be available for the same strength, administration route and dose form. Generic brands needs to demonstrate bioequivalence to the originator brand, but the appearance of the generic and originator brands are not required to match. This variation is possible because different brands may vary in the excipients used in the formulation. Excipients are inactive ingredients, and typically make up about 90% of the formulation of an individual medication. Individual preferences or requirements may affect tolerance of particular excipients, such as the use of animal products. The different appearance of brands can affect medication management for some people. This review discusses the potential for excipients to alter the individual response to or tolerance of a medication brand. PMID- 29169574 TI - The male-female health-survival paradox in hospitalised older adults. AB - OBJECTIVES: To determine whether the 'male-female health-survival paradox' is present in older hospitalised adults and to examine whether sex differences in the 'lethality' of acute medical conditions influence the relationship between sex and mortality. STUDY DESIGN AND OUTCOME MEASURES: This study was a secondary analysis of prospective cohort data collected from 1418 Australian inpatients aged 70 years and over. Frailty was measured using a 39-variable Frailty Index (FI-AC). Analyses examined the relationship between sex, age, FI-AC and 28-day mortality. Survival models were adjusted for 'lethality' of acute conditions (high versus low mortality risk). RESULTS: The FI-AC had a normal distribution in both sexes (female mean=0.34 (+/-0.13); male mean=0.31 (+/-0.15)). When adjusted for age, females had similar FI-AC scores to males (beta coefficient=0.014, 95% confidence interval (CI)=0.00-0.028, p=0.056). There were 80 deaths in the sample, with females facing a significantly lower mortality risk than males of the same FI-AC and age (HR=0.39, 95% CI=0.25-0.63, p<0.001). Females were less likely than males to be admitted with a high-risk acute condition. Even so, this did not significantly reduce their survival advantage (HR=0.46, 95% CI=0.29-0.73, p=0.001). CONCLUSION: The male-female health-survival paradox was not demonstrated in this study of older inpatients. Whilst females faced a significantly lower risk of near-term mortality, the sexes were found to have similar levels of frailty on admission to hospital. The sex mortality gap was not explained by sex differences in the 'lethality' of acute medical conditions. PMID- 29169575 TI - Health determinants and survival in nursing home residents in Europe: Results from the SHELTER study. AB - OBJECTIVE: The care processes directed towards institutionalized older people needs to be tailored on goals and priorities that are relevant for this specific population. The aim of the present study was (a) to describe the distribution of selected health determinants in a sample of institutionalized older adults, and (b) to investigate the impact on survival of such measures. DESIGN: Multicentre longitudinal cohort-study. SETTING: 57 nursing homes (NH) in 7EU countries (Czech Republic, England, Finland, France, Germany, Italy, The Netherlands) and 1 non-EU country (Israel). PARTICIPANTS: 3036 NH residents participating in the Services and Health for Elderly in Long TERm care (SHELTER) study. MEASUREMENTS: We described the distribution of 8 health determinants (smoking habit, alcohol use, body mass index [BMI], physical activity, social participation, family visits, vaccination, and preventive visits) and their impact on 1-year mortality. RESULTS: During the one-year follow up, 611 (20%) participants died. Overweight (HR 0.79; 95% C.I. 0.64-0.97) and obesity (HR 0.64; 95% C.I. 0.48-0.87) resulted associated with lower mortality then normal weight. Similarly, physical activity (HR 0.67; 95% C.I. 0.54-0.83), social activities (HR 0.63; 95% C.I. 0.51-0.78), influenza vaccination (HR 0.66; 95% C.I. 0.55-0.80) and pneumococcal vaccination (HR 0.76 95% C.I. 0.63-0.93) were associated with lower mortality. Conversely, underweight (HR 1.28; 95% C.I. 1.03-1.60) and frequent family visits (HR 1.75; 95% C.I. 1.27-2.42) were associated with higher mortality. CONCLUSIONS: Health determinants in older NH residents depart from those usually accounted for in younger and fitter populations. Ad hoc studies are warranted in order to describe other relevant aspects of health in frail older adults, with special attention on those institutionalized, with the ultimate goal of improving the quality of care and life. PMID- 29169576 TI - Sarcopenia and sarcopenic obesity in Spanish community-dwelling middle-aged and older women: Association with balance confidence, fear of falling and fall risk. AB - OBJECTIVES: To analyze the association of sarcopenia, obesity, and sarcopenic obesity (SO) with fear of falling (FoF) and balance confidence in a Spanish sample of middle-aged and older community-dwelling women. STUDY DESIGN AND OUTCOME MEASURES: A total of 235 women (69.21+/-7.56 years) participated in this study. Body composition (bioelectrical impedance analysis), hand-grip strength, and physical performance (gait speed) were evaluated for the diagnosis of sarcopenia, obesity, and SO. Anxiety and depression were measured using the Hospital Anxiety and Depression Scale. The Activities-Specific Balance Confidence Scale (ABC) and the Falls Efficacy Scale-International (FES-I) were employed to assess FoF and balance confidence, respectively. Scores of >26 on the FES-I and <67% on the ABC were used to identify women at risk of falling. The independent associations of sarcopenia, obesity and SO with FoF, balance confidence, and fall risk were evaluated by multivariate linear and logistic regressions, adjusting for potential confounding variables. RESULTS: 27.23% and 18.72% of women presented with sarcopenia and SO, respectively. Gait speed, body mass index (BMI), and fall history were independently associated with ABC score (adjusted R2=0.152) and fall risk (ABC) (adjusted-R2=0.115). FES-I score was independently associated (adjusted-R2=0.193) with fall history, gait speed, BMI, and depression, which, together with obesity (BMI) and SO, remained independent factors for fall risk measured as FES-I score (adjusted-R2=0.243). CONCLUSION: In community-dwelling middle-aged and older Spanish women, BMI, gait speed, and fall history were independently associated with FoF, balance confidence, and fall risk. Depression was related only to FoF, and, together with obesity (BMI) and SO, was an independent predictor of fall risk as assessed by the FES-I. PMID- 29169578 TI - Post-hysterectomy vaginal vault prolapse. AB - Post-hysterectomy vaginal vault prolapse (PHVP) is a recognised although rare complication following both abdominal and vaginal hysterectomy and the risk is increased in women following vaginal surgery for urogenital prolapse. The management of PHVP remains challenging and whilst many women will initially benefit from conservative measures, the majority will ultimately require surgery. The purpose of this paper is to review the prevalence and risk factors associated with PHVP as well to give an overview of the clinical management of this often complicated problem. The role of prophylactic primary prevention procedures at the time of hysterectomy will be discussed as well as initial conservative management. Surgery, however, remains integral in managing these complex patients and the vaginal and abdominal approach to managing PHVP will be reviewed in detail, in addition to both laparoscopic and robotic approaches. PMID- 29169577 TI - Excess fat in the abdomen but not general obesity is associated with poorer metabolic and cardiovascular health in premenopausal and postmenopausal Asian women. AB - OBJECTIVES: To examine the associations of various metabolites and hormones and hormone replacement therapy (HRT) with obesity. METHODS: This is a cross sectional study of 1326 Singaporean women. A DXA-derived percent body fat (PBF) of >=35% and percent abdominal fat (PAbdF) of >21.8% were used, respectively, to define women with general (GOb) and abdominal (AbdOb) obesity. RESULTS: Higher levels of insulin and glucose, lower levels of HDL, higher levels of TC/HDL and HOMA values, and different levels of some hormones were noted only in the women with abdominal, and not general obesity. The incidence of general and abdominal obesity was higher in postmenopausal women with or without HRT, except that those who were on conjugated estradiol-only HRT had no increase in the incidence of general obesity compared with premenopausal women. CONCLUSIONS: Abdominal obesity is associated with insulin resistance and with higher risks of metabolic syndrome and cardiovascular diseases, whereas general obesity is not. Abdominal obesity may predispose to a higher risk of diabetes. The onset of the menopause tends to increase the incidence of general and abdominal obesity, except that postmenopausal women on conjugated estradiol HRT appear to be relatively protected from general obesity. PMID- 29169579 TI - Data Registry on Experiences of Aging, Menopause, and Sexuality (DREAMS): A cohort profile. AB - The Women's Health Clinic (WHC) at Mayo Clinic in Rochester, Minnesota, has provided consultative care to women with menopausal and sexual health concerns since 2005. Clinical information on the 8688 women seen in the WHC through May 2017 who gave consent for the use of their medical records in research is contained in the Data Registry on Experiences of Aging, Menopause, and Sexuality (DREAMS). Initially, DREAMS was created to improve the clinical care of women, but it has become a valuable research tool. About 25% of the DREAMS women have been seen in the WHC 2 or more times, allowing for passive longitudinal follow up. Additionally, about 25% of the DREAMS women live in the 27-county region included in the expanded Rochester Epidemiology Project medical records linkage system, providing additional information on those women. The cohort has been used to investigate associations between: caffeine intake and vasomotor symptom bother; recent abuse (physical, sexual, verbal, and emotional) and menopausal symptoms; specific menopausal symptoms and self-reported view of menopause; and obstructive sleep apnea risk and vasomotor symptom severity and the experience of vasomotor symptoms in women older than 60 years. A study nearing completion describes a clinical series of over 3500 women presenting for sexual health consultation by sexual function domain and by decade of life. Other studies under way are determining correlates with sexual health and dysfunction. Planned studies will investigate associations between the experience with menopause and the risk of disease. PMID- 29169580 TI - The effects of frailty and cognitive impairment on 3-year mortality in older adults. AB - OBJECTIVES: Frailty and cognitive impairment in late life increase the risk of mortality. Physical frailty is closely associated with cognitive impairment. The aim of the study was to examine the independent and interaction effects of frailty and cognitive impairment in predicting mortality. STUDY DESIGN: A nationally representative sample of community-dwelling Koreans aged 65 years and older (n=11,266) was followed for 3 years. MAIN OUTCOME MEASURES: Frailty was categorized using Fried's phenotype model. Cognitive impairment was defined as more than 1.5 standard deviations below the age-, gender-, and education-specific norm of the Mini-Mental State Examination. Cox proportional hazards regression was used to analyze the mortality risk by frailty status and the moderating effect of cognitive impairment. RESULTS: Frailty was associated with cognitive impairment, with 922 (19.1%), 1609 (28.1%), and 392 (42.8%) of the nonfrail, prefrail, and frail group, respectively, being cognitively impaired. Compared with the nonfrail group, those who were prefrail (hazard ratio [HR]=1.38; 95% confidence interval [CI]: 1.10, 1.73) and frail (HR=1.78, 95% CI: 1.29, 2.46) had higher mortality rates, after adjusting for sociodemographic variables, health behaviors, and chronic conditions. Cognitive impairment was associated with a 30% increased mortality rate. A significant interaction between frailty and cognitive impairment was observed (p=0.003). Compared with those nonfrail and not cognitively impaired, frail persons with cognitive impairment had a lower survival rate (HR=1.92, 95% CI: 1.26, 2.93). CONCLUSIONS: Frailty was a significant predictor of 3-year mortality in community-dwelling older adults, with the association being moderated by baseline cognitive status. Taking cognitive function into account may allow better prediction of adverse outcomes of frailty in later life. PMID- 29169581 TI - Vitamin D status is associated with executive function a decade later: Data from the Women's Healthy Ageing Project. AB - OBJECTIVES: Vitamin D deficiency has been associated with cognitive decline and dementia in older adults. However, there is a paucity of studies assessing whether this association manifests from midlife. Given the long prodromal stage of dementia, we investigated the association between midlife vitamin D and cognition 10 years later. STUDY DESIGN: 252 participants (aged 55-67 years) from the Women's Healthy Ageing Project had baseline (2002) vitamin D and neuropsychological measures assessed. Of these, 170 (aged 65-77 years) had follow up neuropsychological testing (2012). OUTCOME MEASURES: Serum 25-hydroxyvitamin D (25[OH]D) was measured using an automated chemiluminescence system. The neuropsychological tests used were: Consortium to Establish a Registry for Alzheimer's Disease (CERAD), California Verbal Learning Test Second Edition (CVLT II), verbal fluency and Trail Making Test-B (TMT-B). Composite scores for verbal episodic memory (CERAD and CVLT-II) and executive function (verbal fluency and TMT-B) were obtained by summating standardized scores for each test. RESULTS: Analyses were adjusted for age, education and body mass index (BMI). Further adjustment for physical activity, depression, vascular risk factors, supplementation and APOE4-genotype did not materially change the results. At baseline, those with vitamin D>25nmol/L performed better on verbal fluency (beta=2.46, 95%CI=0.53,4.40) and TMT-B time (beta=-18.23, 95%CI=-32.86,-3.61), with higher executive function (beta=1.40, 95%CI=0.44,2.37). These relationships persisted 10 years later for TMT-B (beta=-15.38, 95%CI=-30.82,0.07) and executive function (beta=1.05, 95%CI=0.14,1.95). There were no associations with tests of verbal episodic memory. CONCLUSION: Midlife vitamin D>25nmol/L is associated with improved aspects of executive function in ageing. Findings highlight a potential therapeutic age window where midlife vitamin D repletion could be neuroprotective against cognitive decline.

AB - OBJECTIVE: A likely contributor to pelvic floor disorders is injury and degradation of connective tissue components such as collagen and elastin, leading to weakening of the pelvic floor. Prior studies have found similar connective tissue component changes in women with cervical insufficiency (CI). However, the connection between pelvic floor disorders and cervical insufficiency has not previously been evaluated. Our objective was to determine whether a history of cervical insufficiency is associated with an increased risk of pelvic organ prolapse and stress urinary incontinence after controlling for confounders. STUDY DESIGN: The study used de-identified clinical data from a large multi-institution electronic health records HIPAA-compliant data web application, Explorys Inc. (Cleveland, Ohio, USA). Women with a history of at least one prior delivery after at least 20 weeks' gestation between the years 1999 and 2016 were identified. Logistic regression models were used to identify risk factors and adjust for confounders. MAIN OUTCOME MEASURES: The primary outcome was subsequent development of either stress incontinence or pelvic organ prolapse. RESULTS: A total of 1,182,650 women were identified, of whom 30,890 (2.6%) had a history of cervical cerclage or insufficiency. A history of cervical insufficiency was associated with an increased risk of either pelvic organ prolapse or stress urinary incontinence (aOR=1.93, 95%CI: 1.84-2.02). A history of cervical insufficiency was more strongly associated with an increased risk of pelvic organ prolapse (aOR=2.06, 95%CI: 1.91-2.21) than with stress urinary incontinence (aOR=1.91, 95%CI: 1.80-2.02). CONCLUSION: A history of cervical insufficiency is associated with an increased risk of development of pelvic organ prolapse and stress urinary incontinence. PMID- 29169583 TI - Gender-specific associations between quality of life and leukocyte telomere length. AB - We conducted a study on the relationship between leukocyte telomere length (LTL) and quality of life (QoL) in 82 couples aged 55 and older. LTL was measured by quantitative real-time PCR. QoL was evaluated using the physical component score (PCS) and mental component score (MCS) on the Korean version of the Short-Form Health Survey (SF-36). LTL was found to be independently associated with the SF 36 PCS in males (beta=0.014, p=0.03) and the SF-36 MCS in females (beta=1.16, p<0.01). Thus LTL is associated with QoL in gender-specific ways. PMID- 29169584 TI - Calcium in the prevention of postmenopausal osteoporosis: EMAS clinical guide. AB - INTRODUCTION: Postmenopausal osteoporosis is a highly prevalent disease. Prevention through lifestyle measures includes an adequate calcium intake. Despite the guidance provided by scientific societies and governmental bodies worldwide, many issues remain unresolved. AIMS: To provide evidence regarding the impact of calcium intake on the prevention of postmenopausal osteoporosis and critically appraise current guidelines. MATERIALS AND METHODS: Literature review and consensus of expert opinion. RESULTS AND CONCLUSION: The recommended daily intake of calcium varies between 700 and 1200mg of elemental calcium, depending on the endorsing source. Although calcium can be derived either from the diet or supplements, the former source is preferred. Intake below the recommended amount may increase fragility fracture risk; however, there is no consistent evidence that calcium supplementation at, or above, recommended levels reduces risk. The addition of vitamin D may minimally reduce fractures, mainly among institutionalised people. Excessive intake of calcium, defined as higher than 2000mg/day, can be potentially harmful. Some studies demonstrated harm even at lower dosages. An increased risk for cardiovascular events, urolithiasis and even fractures has been found in association with excessive calcium intake, but this issue remains unresolved. In conclusion, an adequate intake of calcium is recommended for general bone health. Excessive calcium intake seems of no benefit, and could possibly be harmful. PMID- 29169585 TI - Socio-economic indicators and diet quality in an older population. AB - PURPOSE: To examine the strength and independence of associations between three major socio-economic indicators (income, education and occupation) and diet quality (DQ) at baseline and after 20-year follow-up. METHODS: Cross-sectional and longitudinal analyses using data collected in the Rotterdam Study, a prospective population-based cohort. Participants were categorised according to socio-economic indicators (education, occupation and household income) measured at baseline (1989-1993). Participants aged 55 years or older were included (n=5434). DQ was assessed at baseline (1989-1993) and after 20 years (2009-2011) and quantified using the Dutch Healthy Diet Index, reflecting adherence to the Dutch guidelines for a healthy diet; scores can range from 0 (no adherence) to 80 (optimal adherence). Linear regression models were adjusted for sex, age, smoking status, BMI, physical activity level, total energy intake and mutually adjusted for the other socio-economic indicators. RESULTS: At baseline, scores on the Dutch Healthy Diet Index were 2.29 points higher for participants with the highest level of education than for those with the lowest level (95%CI=1.23 3.36); in addition, they were more likely to have a higher DQ at follow-up (beta=3.10, 95%CI=0.71-5.50), after adjustment for baseline DQ. In contrast, higher income was associated with lower DQ at follow-up (beta=-1.92, 95%CI=-3.67, -0.17), whereas occupational status was not associated with DQ at baseline or at follow-up. CONCLUSION: In our cohort of Dutch participants, a high level of education was the most pronounced socio-economic indicator of high DQ at baseline and at follow-up. Our results highlight that different socio-economic indicators influence DQ in different ways. PMID- 29169586 TI - The prevalence of urinary incontinence in nulliparous adolescent and middle-aged women and the associated risk factors: A systematic review. AB - Urinary incontinence (UI) has been defined as the complaint of involuntary loss of urine. There is a general belief that UI is experienced almost exclusively by the elderly and women who have given birth. However, epidemiological studies report that young women who are nulliparous also experience UI. The aim of this study was to systematically review studies investigating the prevalence of UI in nulliparous adolescent and middle-aged women and to provide an overview of risk factors associated with UI. The electronic databases PubMed, EMBASE, CINAHL, and Cochrane Library were systematically searched for eligible studies. Inclusion and exclusion criteria were defined a priori. The selected studies were reviewed and data extraction was carried out by the reviewers. Two independent researchers assessed the quality of the included studies. Eighteen studies were included in this systematic review. UI prevalence estimates varied from 1% to 42.2%. Among the women with UI of any type, 12.5% to 79% had stress urinary incontinence. BMI, childhood enuresis, and high-impact exercising were found to be the main associated risk factors. Understanding the effect of the risk factors on the pelvic floor will enable us to implement preventive strategies and advise appropriately on the prevention of UI. PMID- 29169587 TI - Multimorbidity and perceived stress: a population-based cross-sectional study among older adults across six low- and middle-income countries. AB - BACKGROUND: Stress in chronic conditions or multimorbidity (>=2 chronic conditions) has been reported to affect clinical outcomes but there are no studies on the association between stress and chronic conditions/multimorbidity among older adults in low- and middle-income countries (LMICs). Thus, we investigated this association among adults aged >=50 years across six LMICs. METHODS: A cross-sectional analysis using data from the World Health Organization's Study on Global Ageing and Adult Health (China, Ghana, India, Mexico, Russia, South Africa) was conducted. A perceived stress score [range 0 (lowest stress) -100 (highest stress)] was computed based on two questions from the Perceived Stress Scale. Thirteen chronic conditions were assessed. Multivariable linear regression analyses were conducted. RESULTS: 34,129 adults with a mean age of 62.4 (SD=16.0)years (52.1% females) were included. Overall, 56.6% (95% CI=55.0%-58.2%) had multimorbidity. In the adjusted model including all countries, compared with those with no chronic conditions, higher numbers of chronic conditions were significantly associated with higher stress levels, dose dependently. In a countrywide meta-analysis, multimorbidity was associated with significantly higher stress levels in all countries (especially India and Ghana) although characterized by moderate heterogeneity (I2=54.6%). For single chronic conditions, notably high stress scores were observed for depression, stroke, and hearing problems. CONCLUSION: Chronic conditions and multimorbidity are associated with higher levels of stress in older adults in LMICs. Given that perceived stress and chronic conditions are collectively associated with worse health outcomes, low-cost, population-level integrated interventions to address stress among those with chronic conditions are urgently needed. PMID- 29169588 TI - Changes in hormonal and metabolic parameters in transgender subjects on cross-sex hormone therapy: A cohort study. AB - OBJECTIVES: Gender identity disorder is defined as a strong and persistent cross gender identification that is associated with a remarkable uneasiness of living in an incongruent gender (gender dysphoria). We performed a retrospective study on the hormonal and metabolic effects of cross-sex hormone therapy (CSHT) in a small cohort of transgender patients. STUDY DESIGN: Retrospective study. MEAN OUTCOME MEASURES: Hormonal and biochemical parameters at baseline (i.e. before commencement of CSHT) and while on CSHT in 32 patients (21 male to female [MtF], 11 female to male [FtM]) referred to our Endocrinology Unit for gender dysphoria between January 2012 and February 2017. RESULTS: Compared with baseline, in MtF patients systolic blood pressure, red cell count, hemoglobin, hematocrit and total testosterone decreased significantly, while 17-beta estradiol and SHBG increased significantly and trendwise significantly, respectively. In FtM patients, total testosterone, red cell count, hemoglobin, hematocrit, creatinine, gamma-glutamyl transferase and alkaline phosphatase increased significantly, while fasting plasma glucose decreased trendwise significantly. In MtF patients 17-beta estradiol correlated positively with SHBG and alkaline phosphatase and negatively with total cholesterol and HDL-c, whereas total testosterone correlated positively with systolic blood pressure, red cell count and hematocrit, and negatively with SHBG. In FtM patients total testosterone correlated positively with creatinine and alkaline phosphatase, while 17-beta estradiol correlated positively with HDL-c. CONCLUSIONS: Our data are partly in line with other studies concerning the impact of CSHT on hormonal and metabolic parameters in transgender people. Metabolic changes appear, overall, to be modest, confirming the safety of CSHT. PMID- 29169589 TI - Vitamin D deficiency is associated with metabolic syndrome in postmenopausal women. AB - OBJECTIVE: To evaluate the association between vitamin D (VD) deficiency and risk factors for metabolic syndrome (MetS) in postmenopausal women. STUDY DESIGN: Observational, cross-sectional cohort study. MAIN OUTCOME MEASURES: In this study, 463 women, aged 45-75 years, with amenorrhea >12months, without VD supplementation or established cardiovascular disease were included. Clinical and anthropometric data were collected. Biochemical parameters, including total cholesterol (TC), HDL, LDL, triglycerides, glucose, insulin and 25-hydroxyvitamin D [25(OH)D] were measured. Women meeting three or more of the following criteria were diagnosed with MetS: waist circumference >88cm, triglycerides >=150mg/dL, HDL <50mg/dL, blood pressure >=130/85mmHg and glucose >=100mg/dL. Serum 25(OH)D levels were classified as sufficient (>=30ng/mL), insufficient (20-29ng/mL) or deficient (<20ng/mL). ANOVA, chi-square test and logistic regression (odds ratio, OR) were used for statistical analysis. RESULTS: Serum 25(OH)D levels were sufficient in 148 women (32.0%), insufficient in 151 (32.6%) and deficient in 164 (35.4%). Women with low 25(OH)D levels had higher TC, triglycerides, insulin and HOMA-IR levels (p<0.05). MetS was detected in 57.8% (182/315) of women with hypovitaminosis D (insufficient and deficient) and in 39.8% (59/148) of those with sufficient VD (p=0.003). In a multivariate logistic regression analysis, a low 25(OH)D level (<30ng/mL) was significantly associated with MetS (OR1.90, 95%CI=1.26-2.85), high triglyceride levels (OR1.55, 95%CI=1.13-2.35), and low HDL levels (OR1.60, 95%CI=1.19-2.40) (p<0.05) compared with women with sufficient 25(OH)D levels, after adjusting for age, time since menopause, body mass index, smoking and physical exercise. The mean concentration of 25(OH)D decreased with increasing numbers of MetS components (p=0.016). CONCLUSIONS: VD deficiency in postmenopausal women was associated with a higher prevalence of MetS. Women with VD deficiency had a higher risk of MetS, hypertriglyceridemia and low HDL than those with adequate levels. PMID- 29169590 TI - Open Fractures of the Hand: Review of Pathogenesis and Introduction of a New Classification System. AB - Open fractures of the hand are a common and varied group of injuries. Although at increased risk for infection, open fractures of the hand are more resistant to infection than other open fractures. Numerous unique factors in the hand may play a role in the altered risk of postinjury infection. Current systems for the classification of open fractures fail to address the unique qualities of the hand. This article proposes a novel classification system for open fractures of the hand, taking into account the factors unique to the hand that affect its risk for developing infection after an open fracture. PMID- 29169591 TI - Radial Nerve Palsy After Humeral Shaft Fractures: The Case for Early Exploration and a New Classification to Guide Treatment and Prognosis. AB - Radial nerve palsies are a common complication associated with humeral shaft fractures. The authors propose classifying these injuries into 4 types based on intraoperative findings: type 1 stretch/neuropraxia, type 2 incarcerated, type 3 partial transection, and type 4 complete transection. The initial management of radial nerve palsies associated with closed fractures of the humerus remains a controversial topic, with early exploration reserved for open fractures, fractures that cannot achieve an adequate closed reduction requiring fracture repair, fractures with associated vascular injuries, and polytrauma patients. Outside of these recommendations, expectant observation for spontaneous recovery is recommended. PMID- 29169592 TI - Distal Radius Fractures in a Functional Quadruped: Spanning Bridge Plate Fixation of the Wrist. AB - Patients who require assistive devices with their hands for mobilization are called functional quadrupeds. These patients pose a unique challenge after they have a distal radius fracture, as their injury not only limits the wrist but also compromises ambulation. The authors propose a different treatment strategy for functional quadrupeds to improve mobilization and weight-bearing with the injured limb after a distal radius fracture. In this article, the authors define the functional quadruped and describe their technique of spanning bridge plate fixation with a retrospective review of patient outcomes. PMID- 29169593 TI - "Damage Control" Hand Surgery: Evaluation and Emergency Management of the Mangled Hand. AB - Mangled hand injuries are defined as those with significant damage to multiple structures, which may be limb threatening. Historically these injuries resulted in amputation or death, but modern surgical and perioperative advances allow for complex reconstruction and the possibility of a sensate and functional limb. Evaluation begins with surveying for life-threatening injuries followed by a systematic approach to identify injured structures; management begins with preserving all parts, minimizing warm ischemia time, performing debridement, and planning an operative approach to optimize the chance of a functional limb. With careful surgical planning and a well-executed reconstruction, most limbs can be salvaged. PMID- 29169594 TI - Carpal Tunnel Syndrome and Distal Radius Fractures. AB - Carpal tunnel syndrome (CTS) after distal radius fractures can present in 3 forms: acute, transient, and delayed. Acute CTS requires an emergent carpal tunnel release. Many patients with transient CTS after distal radius fracture do not require surgical release of the carpal tunnel once the fracture is repaired. Prophylactic carpal tunnel release in the absence of signs and symptoms of CTS after a distal radius fracture is not indicated. For patients with delayed CTS after a distal radius fracture, all possible causes of nerve compression should be considered and addressed in standard fashion. PMID- 29169595 TI - Open Distal Radius Fractures: Timing and Strategies for Surgical Management. AB - Open distal radius fractures are rare injuries with few studies to guide treatment. Degree of soft tissue injury and contamination may be a primary consideration to dictate timing and operative intervention. Antibiotics should be started as early as possible and include a first-generation cephalosporin. Surgical fixation remains a matter of surgeon preference: although studies support the use of definitive internal fixation, many surgeons address contaminated injuries with external fixation. Although postoperative outcomes are similar to closed injuries for low-grade open distal radius fractures, high-grade injuries with more complex fracture patterns carry a high risk of complications, poor outcomes, and repeat surgical procedures. PMID- 29169596 TI - Hand Compartment Syndrome. AB - Acute hand compartment syndrome is a potentially devastating condition a hand surgeon may be called on to evaluate and treat. This pathophysiologic cascade of events that begins with an inciting event progresses to increased intracompartmental pressure, tissue necrosis, and resultant morbidity and potentially mortality. Many patients present with an altered sensorium, making the diagnosis challenging, requiring the clinician to rely on clinical findings and intracompartmental pressure measurements. The timing to definitive treatment with complete decompressive fasciotomies is critical to optimize patient outcomes. The goals of treatment are to prevent contracture, functional disability, and the loss of limb or life. PMID- 29169597 TI - Forearm Compartment Syndrome: Evaluation and Management. AB - Compartment syndrome of the forearm is uncommon but can have devastating consequences. Compartment syndrome is a result of osseofascial swelling leading to decreased tissue perfusion and tissue necrosis. There are numerous causes of forearm compartment syndrome and high clinical suspicion must be maintained to avoid permanent disability. The most widely recognized symptoms include pain out of proportion and pain with passive stretch of the wrist and digits. Early diagnosis and decompressive fasciotomy are essential in the treatment of forearm compartment syndrome. Closure of fasciotomy wounds can often be accomplished by primary closure but many patients require additional forms of soft tissue coverage procedures. PMID- 29169598 TI - Traumatic Wounds of the Upper Extremity: Coverage Strategies. AB - Soft tissue coverage of traumatic wounds of the upper extremity is often required to restore adequate function and form. An optimal coverage should be stable, durable, and able to withstand heavy demands of work, should allow free joint mobility, and should have an aesthetically acceptable appearance. Reconstructive options for coverage include autologous tissue and dermal skin substitutes. Multiple factors, including wound characteristics and complexity, general condition of the patient, and surgeon comfort and expertise, help in selection of the reconstructive technique. This article summarizes commonly used soft tissue reconstructive options for traumatic wounds of the upper extremity. PMID- 29169599 TI - Elbow Fractures with Instability: Evaluation and Treatment Strategies. AB - The treatment goals of elbow fracture dislocations are congruent reduction of the ulnohumeral and radiocapitellar joints, stable fixation of the proximal ulna, stable fixation or arthroplasty of the radial head, and soft tissue repair. Fracture dislocations occur in patterns, and recognition of these patterns help guide surgical treatment. In patients with persistently unstable fractures after standard fixation, additional temporary joint spanning implants are useful to protect repairs. PMID- 29169600 TI - Arterial Injury in the Upper Extremity: Evaluation, Strategies, and Anticoagulation Management. AB - Trauma to the upper extremity can present with an associated arterial injury. After patient stabilization, thorough assessment with physical examination and various imaging modalities allows accurate diagnosis of the specific arterial injury. After diagnosis, efficient treatment is necessary to allow limb salvage. Treatment options include ligation, primary repair, graft reconstruction, endovascular repair, and amputation. The final treatment rendered is frequently dependent on injury location and mechanism. With any of the treatment options, complications may occur, including thrombosis. Currently, no validated anticoagulation protocol has been established for managing arterial injuries in the upper extremity. PMID- 29169601 TI - Antibiotic Management and Operative Debridement in Open Fractures of the Hand and Upper Extremity: A Systematic Review. AB - Open fractures of the hand are thought to be less susceptible to infection than other open fractures because of the increased blood supply to the area. Current evidence for all open fractures shows that antibiotic use and the extent of contamination are predictive of infection risk, but time to debridement is not. We reviewed in a systematic review the available literature on open fractures of the hand and upper extremity to determine infection rates based on the timing of debridement and antibiotic administration. We continue to recommend prompt debridement and treatment of most open fractures of the upper extremity. PMID- 29169602 TI - Ulnar Nerve Management with Distal Humerus Fracture Fixation: A Meta-Analysis. AB - Ulnar nerve dysfunction following distal humerus fractures is a well-recognized phenomenon. There is no consensus regarding optimal handling of the ulnar nerve during surgical management of these fractures between in situ management and transposition. Using an electronic database to identify retrospective studies involving surgical fixation of distal humerus fractures yielded 46 studies, 5 trials meeting the authors' inclusion criteria, totaling 362 patients. An overall incidence of 19.3% for ulnar neuropathy was identified. Of those patients undergoing in situ release, the incidence was 15.3%. Of those who underwent transposition, there was a 23.5% incidence of ulnar neuropathy. PMID- 29169603 TI - Complex Trauma Management of the Upper Extremity. PMID- 29169604 TI - Validation of Peripherally Inserted Central Catheter-Derived Fick Cardiac Outputs in Patients with Heart Failure. AB - The pulmonary artery catheter (PAC) remains the gold standard to calculate Fick cardiac outputs (FCOs) in patients with heart failure admitted to the intensive care unit (ICU). The peripherally inserted central catheter (PICC) provides long term intravenous access and is used outside the ICU; however, there is scant literature validating venous oxygen saturations (VOSs) from PICC lines. Heart failure patients in the ICU with an existing PAC requiring a PICC line to transition were enrolled. Three blood samples were taken per person (1 at PICC, 1 at central venous pressure [CVP], and 1 at distal PAC). We performed repeated measures analysis of variance, as well as reliability analysis on 31 subjects (77% male, 71% Caucasian, mean +/- standard deviation age 60 +/- 8 years, 80% on inotropes). The average VOSs were 62 +/- 11%, 62 +/- 12%, and 61 +/- 9% for the PICC line, CVP, and distal port, respectively (p = 0.66); there was excellent reliability (0.79). The median FCOs were 5 [4, 6], 5 [4, 6], and 5 [4, 6] L/min at the PICC, CVP, and distal port, respectively (p = 0.91); there was fair-to good reliability (0.67). In conclusion, VOS and FCO did not differ by location, on average. Reliable data may be obtained through the PICC line, after evaluation from the PAC. The PICC may provide longer-term hemodynamic assessment while improving patient comfort. PMID- 29169605 TI - Relation of Stroke and Bleeding Risk Profiles to Efficacy and Safety of Edoxaban for Cardioversion of Atrial Fibrillation (from the EdoxabaN versus warfarin in subjectS UndeRgoing cardiovErsion of Atrial Fibrillation [ENSURE-AF] Study). AB - In the EdoxabaN versus warfarin in subjectS UndeRgoing cardiovErsion of Atrial Fibrillation (ENSURE-AF) study, edoxaban was compared with enoxaparin-warfarin in patients who underwent electrical cardioversion of nonvalvular atrial fibrillation, showing comparable low rates of bleeding and thromboembolism. The present study is an ancillary analysis investigating differences in relation to stroke and bleeding risk profiles. It also determined the relation of patients' clinical risk profiles to the quality of anticoagulation control in the warfarin arm. Primary efficacy (composite of stroke, systemic embolic event, myocardial infarction, and cardiovascular death) and safety (composite of major and clinically relevant nonmajor bleeding) outcomes and time to therapeutic range (TtTR) and time in therapeutic range (TiTR) were analyzed in relation to CHA2DS2 VASc (congestive heart failure, hypertension, age >=75 years (2 points), diabetes mellitus, stroke (2 points), vascular disease, age 65-74 years, sex category) and HAS-BLED (hypertension, age, stroke, bleeding tendency/predisposition, labile INRs, elderly age/frailty, drugs such as concomitant aspirin/nonsteroidal anti inflammatory drugs or alcohol excess) scores. A total of 1,095 patients were randomized to edoxaban and 1,104 received enoxaparin-warfarin. Mean age was 64.3 +/- 10 and 64.2 +/- 11 years, respectively. Mean CHA2DS2-VASc score was 2.6 (standard deviation [SD] 1.5 and 1.4, respectively) and mean HAS-BLED score was 0.9 (SD 0.8) in both arms. There were nonsignificant trends toward lower odds ratios (ORs) for the efficacy end point in patients with CHA2DS2-VASc scores >2 and higher ORs with HAS-BLED score >=3. Mean TiTR was >67%, with no differences between stroke or bleeding risk strata. The correlation between CHA2DS2-VASc and TtTR (p = 0.0286) and HAS-BLED and TiTR (p = 0.0286) were statistically significant. In patients who were at high risk of stroke, edoxaban had numerically lower primary efficacy end-point events and showed a trend for higher ORs, with HAS-BLED scores >=3 compared with enoxaparin-warfarin. TtTR was shorter with higher CHA2DS2-VASc scores, whereas bleeding risk was inversely correlated with quality of anticoagulation control.

AB - OBJECTIVE: To review the spectrum of benign and malignant rectal diseases, their findings on CT colonography, and their management. CONCLUSION: Although CT colonography is not the first choice for the study of rectal disease, it is indicated in cases where optical colonoscopy is contraindicated or cannot be completed. Rectal lesions can go undetected because this anatomic area is difficult to evaluate; for this reason, it is essential to ensure optimal preparation and distension, moderate balloon insufflation, and careful 2D and 3D navigation with knowledge of the spectrum of rectal disease and its CT colonography signs.

AB - Chile has a mixed health system with public and private actors engaged in provision and insurance. This dual system generates important differences in health expenditure between private and public insurances. Selection is a preeminent feature of the Chilean insurance system. In order to explain the role of the insurance in out-of-pocket expenditures between households for different insurance schemes, decomposition methods are applied to disentangle the effect of household 'composition and insurance' degree of financial protection on health expenditures. Health expenditure patterns have not changed in the last 10 years with drugs, outpatient care, and dental health representing 60% of the health expenditure. Health expenditure/income is similar for different income groups in the public insurance, but decreases with income in households with private coverage, reflecting regressivity in health expenditure. On the other hand, health expenditure as share of expenditure increases with income for both groups. Per capita health expenditure in households with private coverage is four times the expenditure of households with public insurance; this gap is mostly explained by differences in households' expenditure and demographics. Roughly 80% of the difference in expenditure is explained by the model, showing the role of selection in understanding the expenditure gap between insurance schemes. PMID- 29169611 TI - The Conduct and Reporting of Child Health Research: An Analysis of Randomized Controlled Trials Published in 2012 and Evaluation of Change over 5 Years. AB - OBJECTIVES: For child health randomized controlled trials (RCTs) published in 2012, we aimed to describe design and reporting characteristics and evaluate changes since 2007; assess the association between trial design and registration and risk of bias (RoB); and assess the association between RoB and effect size. STUDY DESIGN: For 300 RCTs, we extracted design and reporting characteristics and assessed RoB. We assessed 5-year changes in design and reporting (based on 300 RCTs we had previously analyzed) using the Fisher exact test. We tested for associations between design and reporting characteristics and overall RoB and registration using the Fisher exact, Cochran-Armitage, Kruskal-Wallis, and Jonckheere-Terpstra tests. We pooled effect sizes and tested for differences by RoB using the chi2 test for subgroups in meta-analysis. RESULTS: The 2012 and 2007 RCTs differed with respect to many design and reporting characteristics. From 2007 to 2012, RoB did not change for random sequence generation and improved for allocation concealment (P < .001). Fewer 2012 RCTs were rated high overall RoB and more were rated unclear (P = .03). Only 7.3% of 2012 RCTs were rated low overall RoB. Trial registration doubled from 2007 to 2012 (23% to 46%) (P < .001) and was associated with lower RoB (P = .009). Effect size did not differ by RoB (P = .43) CONCLUSIONS: Random sequence generation and allocation concealment were not often reported, and selective reporting was prevalent. Measures to increase trialists' awareness and application of existing reporting guidance, and the prospective registration of RCTs is needed to improve the trustworthiness of findings from this field. PMID- 29169609 TI - Microglia-Mediated Neuroprotection, TREM2, and Alzheimer's Disease: Evidence From Optical Imaging. AB - Recent genetic studies have provided overwhelming evidence of the involvement of microglia-related molecular networks in the pathophysiology of Alzheimer's disease (AD). However, the precise mechanisms by which microglia alter the course of AD neuropathology remain poorly understood. Here we discuss current evidence of the neuroprotective functions of microglia with a focus on optical imaging studies that have revealed a role of these cells in the encapsulation of amyloid deposits ("microglia barrier"). This barrier modulates the degree of plaque compaction, amyloid fibril surface area, and insulation from adjacent axons thereby reducing neurotoxicity. We discuss findings implicating genetic variants of the microglia receptor, triggering receptor expressed on myeloid cells 2, in the increased risk of late onset AD. We provide evidence that increased AD risk may be at least partly mediated by deficient microglia polarization toward amyloid deposits, resulting in ineffective plaque encapsulation and reduced plaque compaction, which is associated with worsened axonal pathology. Finally, we propose possible avenues for therapeutic targeting of plaque-associated microglia with the goal of enhancing the microglia barrier and potentially reducing disease progression.

Then we reviewed our results applying this approach in patients with colorectal liver metastases in contact with hepatic veins at the caval-confluence. METHODS: A cohort of consecutive patients with colorectal liver metastases in contact with hepatic veins at the caval-confluence undergoing liver surgery was reviewed. Relationships were classified as: Type 1: contact/involvement less than a third of hepatic vein circumference; Type 2: contact/involvement in a third to two thirds; Type 3: contact/involvement in more than two-thirds. Hepatic vein- colorectal liver metastases detachment, or in case of hepatic vein-resection, the sparing of the drained parenchyma, were attempted systematically. RESULTS: Overall 190 colorectal liver metastases-hepatic vein contacts in 135 patients were analyzed. Colorectal liver metastases-hepatic vein detachment was performed in 95 (50%) contacts, partial resection and direct suture in 61 (32%), partial resection and patching in 4 (2%), and hepatic vein complete resection in 30 (16%). Hepatic vein-sparing resection was possible in 102 patients (76%), and major hepatectomy was needed in 1 (0.7%). Operative mortality, overall and major morbidity rate were 0.7%, 32%, and 4%, respectively. Local recurrence rate was 6% (median follow-up: 27 months). Preoperative and intraoperative imaging predicted the need for hepatic vein resection in 99% of patients (kappa = 0.971). CONCLUSIONS: Hepatic vein-sparing or a parenchyma-sparing policy is feasible in most patients with colorectal liver metastases-hepatic vein contacts at the caval confluence. This approach seems safe, predictable, and oncologically adequate, and, upon further confirmation, could become an alternative to major hepatectomies or hepatic vein replacement.

PMID- 29169614 TI - Human papillomavirus viral load as a useful triage tool for non-16/18 high-risk human papillomavirus positive women: A prospective screening cohort study. AB - OBJECTIVE: ASCCP cervical cancer screening guidelines recommend triaging high risk human papillomavirus (hrHPV) positive women with cytology and genotyping, but cytology is often unavailable in resource-limited areas. We compared the long term risk of cervical cancer and precancers among type-specific hrHPV-positive women triaged by viral load to cytology and visual inspection with acetic acid (VIA). METHODS: A cohort of 1742 Chinese women was screened with cytology, VIA, and Hybrid Capture 2 (HC2) test and followed for ten years. All HC2-positive samples were genotyped. Viral load was measured by HC2 relative light units/cutoff (RLU/CO). Ten-year cumulative incidence rate (CIR) of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) for type-specific hrHPV viral load was estimated using Kaplan-Meier methods. RESULTS: Baseline hrHPV viral load stratified by specific genotypes was positively correlated with prevalent cytological lesions. Ten-year CIR of CIN2+ was associated with cytological lesions and viral load. Among HPV 16/18-positive women, ten-year CIR of CIN2+ was high, even with normal cytology (15.3%), normal VIA (32.4%), viral load with RLU/CO<10 (23.6%) or RLU/CO<100 (33.8%). Among non-16/18 hrHPV positive women, ten-year CIR of CIN2+ was significantly stratified by cytology grade of atypical squamous cell of undetermined significance or higher (2.0% VS. 34.6%), viral load cutoffs at 10 RLU/CO (5.1% VS. 27.2%), at 100 RLU/CO (11.0% VS. 35.5%), but not by VIA (19.1% VS. 19.0%). CONCLUSIONS: Our findings support the guidelines in referring all HPV16/18 positive women to colposcopy and suggest triaging non 16/18 hrHPV positive women using viral loads in resource-limited areas where cytology screening was inaccessible.

AB - OBJECTIVE: To investigate the morbidity of diverting loop ileostomy (DLI) performed during Visceral Peritoneal Debulking (VPD) for stage IIIC-IV ovarian cancer and to report the rate, timing, and morbidity of DLI reversal. METHODS: We retrieved the data of all consecutive patients who underwent sigmoid-rectum resection (SRR) followed by DLI. Morbidity was defined as any surgical/medical complications clearly correlated to the DLI. The reversal rate of DLI was defined as the number of patients who had the continuity of the gastrointestinal tract restored in the study period. Finally, we recorded the timing and the morbidity of the reversal surgery. Factors associated with non-reversal of DLI were reported. RESULTS: In the study period (01/2010-09/2016), complete data were available for 47 patients. Stoma-related complications occurred in 22 patients (46.8%). Eight patients (17.0%) were readmitted within 30days from surgery. Thirty-two patients (68.1%) had their stoma reversed. The primary cause of non reversal was tumor recurrence/progression (7/15, 46.7%). Patient's age, length of hospitalization, complications after VPD were associated with non-reversal of DLI. The mean time from DLI formation to stoma reversal was 6months (+/-1.7). Post-reversal related complications occurred in 37.1% of the patients. CONCLUSIONS: In our series, 31.9% of the patients with FIGO stage IIIC-IV ovarian cancer who underwent SRR and DLI did not have stoma reversal. Overall they had approximately 45% risk of stoma-related morbidity and 37% risk of morbidity related to the stoma reversal. This information should be part of the consulting process when preparing for debulking surgery, particularly in patients who are likely to need a bowel resection. PMID- 29169616 TI - Characterizing Microscopical Invasion Patterns in Canine Mast Cell Tumours and Soft Tissue Sarcomas. AB - Stromal invasion is identified commonly in cutaneous malignancies; however, invasive patterns are defined inconsistently and their clinical relevance is uncertain. This study aimed to define objective, quantifiable histomorphological invasive patterns in low-grade canine mast cell tumours (MCTs) and grade I/II soft tissue sarcomas (STSs), and correlate invasive patterns with overall excisional status. Haematoxylin and eosin-stained glass slides prepared for routine histopathology of surgically-excised tumours from client-owned dogs were evaluated for invasion beyond their subgross edge, asymmetrical invasion, satellite lesions, lymphovascular invasion, perineurovascular growth, growth along fascial planes, intramuscular invasion and multicompartmental involvement. Digital histological tumour-free margins <1 mm in any direction were considered to represent an incomplete excision. Fifty-one dogs with 69 tumours (50 MCTs and 19 STSs) were included in the study. Invasion in both circumferential and deep directions was significantly greater in MCTs compared with STSs (exact 2-tailed P <0.0001 circumferential; P = 0.0095 deep). Within the MCT group, circumferential invasion was greater than deep invasion (P = 0.0076). Multivariate logistic regression analysis found two variables that were significantly associated with incomplete MCT excision: intraoperative grossly normal circumferential surgical margin size (odds ratio of 0.776, 95% confidence interval: 0.651-0.925) and asymmetry invasion index (odds ratio of 1.318, 95% confidence interval: 1.039 1.671). These data may help create evidence-based strategies for planning surgical resections of cutaneous malignancies. Presence of asymmetrical microscopical invasion might prompt pathologists to perform more comprehensive surgical margin evaluation. PMID- 29169617 TI - Primary Histiocytic Sarcoma of the Brain in an African Hedgehog (Atelerix albiventris). AB - A 2.5-year-old African hedgehog (Atelerix albiventris) with signs of progressive paresis/paralysis for approximately 6 months was diagnosed with 'wobbly hedgehog syndrome' (WHS). Post-mortem examination revealed a primary central nervous system (CNS) histiocytic sarcoma (HS) associated with neurodegenerative changes of the CNS and skeletal muscle atrophy. Grossly, a spherical mass infiltrated the left forebrain and was located between the frontal lobe and thalamus in coronal sections. Microscopically, the neoplastic cells had eccentrically located anisokaryotic nuclei and abundant eosinophilic cytoplasm. Immunohistochemically, they were positive for calcium-binding adapter molecule 1, lysozyme, CD68 and vimentin. Ultrastructurally, the neoplastic cells had varying amounts of bundles and whorls of intermediate filaments and scattered lysosomes. This report represents the first documentation of primary CNS HS in this species. Primary CNS HS should be considered as a differential diagnoses for hedgehogs that present with neurological signs of WHS. PMID- 29169618 TI - Clinical Pathology of the Vulnerable Gough Moorhen (Gallinula comeri). AB - The Gough moorhen (Gallinula comeri) is native to Gough Island, Tristan da Cunha, and listed as Vulnerable by the International Union for Conservation of Nature due to its restricted range and susceptibility to introduced predators. A planned ecosystem restoration by eradication of introduced house mice (Mus musculus) via aerially delivered rodenticide requires a reproductively balanced population of Gough moorhens to be held in captivity to avoid primary and secondary poisoning. To aid disease detection during the period of captivity, Gough moorhens (n = 43; 25 adult females and 18 adult males) were captured, measured and sampled to determine ease of sexing by morphometrics, to establish reference ranges for routine haematological and biochemical parameters and to identify any intestinal and haemoparasites as well as determine which faecal bacteria were present. Male Gough moorhens had significantly greater mean body mass (P = 0.019) and head and bill length (P = 0.001) compared with females, but the overlapping ranges showed genetic identification of sex was required for accurate determination. Plasma globulin and total protein concentrations were significantly greater in female compared with male birds (P = 0.032 and P = 0.012, respectively) and probably related to egg yolk production. No haemoparasites or gastrointestinal parasites were found in any bird and there were no sex-related differences in the haematology. Multiple bacterial taxa were isolated from the faeces of all birds including Enterococcus spp. (n = 42), Klebsiella spp. (n = 40), Staphylococcus aureus (n = 33), Staphylococcus intermedius (n = 16), Escherichia coli (n = 41) and Pseudomonas spp. (n = 7). No clinical or subclinical disease was found in any of the birds examined, suggesting they are suitable for short-term captivity but rapid on-island genetic-based sex determination will be essential to ensure a reproductively balanced population. PMID- 29169619 TI - Immunohistochemical Validation of Spontaneously Arising Canine Osteosarcoma as a Model for Human Osteosarcoma. AB - Osteosarcoma (OS) originates from bone-forming mesenchymal cells and represents one of the primary bone tumours. It is the most common primary bone tumour in dogs and man. The characterization of an appropriate natural disease animal model to study human OS is essential to elucidate the pathogenesis of the disease. This study aimed to validate canine OS as a model for the human disease by evaluating immunohistochemically the expression of markers known to be important in human OS. The immunohistochemical panel included vimentin, alkaline phosphatase (ALP), desmin, S100, neuron-specific enolase (NSE), runt-related transcription factor 2 (Runx2) and bone morphogenetic protein 4 (BMP4). Immunohistochemistry was conducted on formalin-fixed, paraffin wax-embedded tissue sections from 59 dogs with confirmed primary OS. Vimentin, ALP, Runx2 and BMP4 were highly expressed by all tumours, while desmin, S100 and NSE were expressed variably. The findings were similar to those described previously for human OS and suggest that canine OS may represent a useful model for the study of the human disease. PMID- 29169620 TI - Pancreatic Colloid Carcinoma in an Elderly Cat. AB - A 21-year-old neutered female domestic shorthaired cat was presented with a history of inappetence, vomiting and haematuria. The cat was humanely destroyed at the owner's request and a necropsy examination was performed. A 0.8 * 0.5 * 0.5 cm mass was located in the left lobe of the pancreas. The mass was gelatinous in nature and the external and cut surfaces were pale yellow in colour. Microscopically, the mass was non-capsulated and comprised an accumulation of extracellular stromal mucin containing suspended neoplastic columnar epithelial cells forming tubular structures. Immunohistochemically, these cells diffusely expressed cytokeratin (CK) AE1/AE3, CK7 and carcinoembryonic antigen and were partially positive for CK19 and trypsin, but negative for vimentin. The tumour was diagnosed as a colloid carcinoma. The clinical presentation in this case was caused by chronic renal failure complicated by secondary renal hyperparathyroidism and associated metastatic calcinosis. To the best of our knowledge, this is the first report of colloid carcinoma arising from the pancreas in a cat. PMID- 29169622 TI - Cardiac Truncus Arteriosus in an Eastern Black Rhinoceros (Diceros bicornis michaeli). AB - This case report describes congenital truncus arteriosus in a 1-month-old Eastern black rhinoceros (Diceros bicornis michaeli). From the first day of life the animal was underweight and from the 22nd day of life displayed respiratory signs that exacerbated with time leading eventually to collapse and death. Post-mortem examination revealed a single truncus arteriosus originating from the right ventricle leading to two separated pulmonary arteries and the aorta, with the ventricular septum showing a focal communicating defect. Based on the gross examination and current human classifications, the truncus arteriosus was classified as type III or A2. This is the first description of persistent truncus arteriosus in an Eastern black rhinoceros.

PMID- 29169623 TI - Endocardial Peripheral Nerve Sheath Tumour with Features of a Benign Schwannoma in a Donkey. AB - A peripheral nerve sheath tumour, with features of a benign schwannoma and arising from the endocardium of the right ventricle, was found incidentally during routine post-mortem examination of a 28-year-old gelding donkey. Macroscopically, five round to oval, white to grey and red, firm masses, firmly attached to the endocardium were identified. Microscopically, the endocardium and adjacent subendocardium were infiltrated by a variably demarcated, non encapsulated mesenchymal neoplasm with features of a benign schwannoma, including concurrent presence of Antoni A and Antoni B areas, nuclear palisading, neoplastic cells with enlarged bizarre nuclei ('ancient change') and the formation of Verocay-like bodies. Immunohistochemically, the tumour cells were variably strongly positive for expression of S100 and glial fibrillary acidic protein. This is the first cardiac tumour reported in a donkey and is macroscopically, histologically and immunohistochemically similar to endocardial schwannoma occurring in Wistar rats. PMID- 29169624 TI - Suspected Hepadnavirus Association with a Hepatocellular Carcinoma in a Black Tailed Prairie Dog (Cynomys ludovicianus). AB - Hepatocellular carcinomas are the most commonly reported neoplasm of black-tailed prairie dogs (Cynomys ludovicianus). In several other closely related Sciuridae species, infection with species-specific hepadnaviruses is associated with the development of these tumours, but such a hepadnavirus has not yet been identified in any prairie dog species, although its presence has been hypothesized previously. An adult prairie dog was humanely destroyed due to progressive illness and the identification of a cranial abdominal mass that was determined on histopathology to be a hepatocellular carcinoma. Deep sequencing of the tumour tissue identified the presence of a hepadnavirus, similar in its genetic structure to woodchuck hepatitis virus. Electron microscopy showed the presence of viral particles similar in structure to other hepadnaviral particles. This report suggests that a hepadnavirus may be associated with the development of hepatocellular carcinomas in the prairie dog. PMID- 29169625 TI - Ovarian Embryonal Carcinoma in a Dog. AB - A 17-month-old female doberman pinscher was referred for an abdominal mass and ascites. Exploratory laparotomy revealed the presence of a large neoplastic mass replacing the right ovary and associated with multiple mesovarian, mesometrial and peritoneal nodules. An ovariohysterectomy was performed. Grossly, the tumour was soft and multilocular with large areas of haemorrhage and necrosis. Microscopically, it was infiltrative and composed of round and polygonal cells arranged respectively in solid sheets or forming distorted tubular structures separated by thick fibrovascular septae. Tubules contained necrotic debris, proteinaceous fluid or small endoluminal papillary structures. Marked cellular atypia, multiple neoplastic emboli and high mitotic count were observed. Immunohistochemically, the round cells uniformly expressed placental alkaline phosphatase, while the polygonal cells arranged in tubules and papillae expressed cytokeratin (CK) AE1/AE3 and CK7. A final diagnosis of metastasizing ovarian embryonal carcinoma (EC), a primitive germ cell tumour characterized by rudimentary epithelial differentiation was made. Canine ovarian EC should be considered as a differential diagnosis for undifferentiated aggressive ovarian tumours in young dogs. PMID- 29169626 TI - Intra-oral Sebaceous Gland Tumours in Two Dogs. AB - A 12-year-old female miniature schnauzer and a 12-year-old neutered female cocker spaniel each had a grey-yellow nodular lesion arising from the gingiva. Microscopical examination showed that both nodules were composed of varied proportions of sebocytes and basal-type reserve cells with few ducts lined by stratified squamous epithelium. Based on the histopathological findings, the cases were diagnosed as sebaceous adenoma and sebaceous epithelioma, respectively. In man, the occurrence of sebaceous neoplasms in the oral cavity has been reported to some extent, but these lesions are very rare in animals. To the best of our knowledge, this is the first report of intra-oral sebaceous neoplasms in dogs. Intra-oral sebaceous epithelioma has never been reported in animals. PMID- 29169627 TI - Cytomegalic Inclusion Disease caused by Cytomegalovirus Infection in the Salivary Glands of an African Hedgehog (Atelerix arbiventris). AB - Cytomegalic inclusion disease (CID) in the salivary gland of African hedgehogs (Atelerix arbiventris) has been reported before, and is suspected to reflect a cytomegalovirus infection. However, a recent ultrastructural study reported that African hedgehog CID reflected oncocytic metaplasia, mimicking a cytomegalovirus infection. We examined the submandibular and sublingual salivary glands of a 1 year-old male African hedgehog. Histologically, there were multiple foci composed of cytomegalic cells with intranuclear inclusion bodies. Ultrastructurally, viral particles (109-118 nm in diameter) were observed in the nuclei of the cytomegalic cells. There were numerous vesicles containing various numbers of enveloped viruses in the cytoplasm. We also attempted to detect viral DNA fragments by degenerate polymerase chain reaction and obtained amplicons of a predicted size. Phylogenetic analysis indicated that the virus is a betaherpesvirus, comparatively related to human and rodent cytomegaloviruses. The present study suggested that African hedgehog CIDs also include those caused by the cytomegalovirus. PMID- 29169628 TI - Spinal Cord Compression in a Horse due to a Granular Cell Variant of Neurofibroma. AB - A neurofibroma of granular cell subtype is described in a 7-year-old horse. The horse had a 3-month history of ataxia affecting the forelimbs and hindlimbs, suggesting a C1-C6 neuroanatomical localization. Post-mortem examination revealed an intradural mass arising from the right sixth cervical spinal nerve and compressing the spinal cord. Histologically, the mass was composed largely of wavy spindle cells (a mixture of Schwann cells, perineurial cells and fibroblasts) intimately associated with ropy collagen fibres. Approximately 25% of the spindle cells were swollen and contained densely-packed, eosinophilic and periodic acid-Schiff-positive cytoplasmic granules. Immunohistochemistry for S100 and glial fibrillary acidic protein antigens labelled a proportion of neoplastic cells, while the cytoplasmic granules were positive for S100 and neuron specific enolase. This is the first report of a neurofibroma with granular cell differentiation in an animal. Granular cell differentiation in other peripheral nerve sheath tumours of animals is briefly discussed. PMID- 29169629 TI - Suppurative Inflammation and Local Tissue Destruction Reduce the Penetration of Cefuroxime to Infected Bone Implant Cavities. AB - Treatment of post-traumatic and implant-associated osteomyelitis (IAO) includes surgical debridement, removal of implants and long-term antibiotic therapy. The success of antibiotic therapy relies not only on activity towards the infecting pathogen, but also on sufficient penetration of the target site. The aim of the present study was to characterize the local pathological changes associated with reduced penetration of cefuroxime to infected bone implant cavities. Previously, reduced penetration of systemically administrated cefuroxime was demonstrated in the implant cavity of 10 pigs with Staphylococcus aureus IAO present for 5 days. In the present study, a comprehensive histopathological characterization of the peri-implant bone tissue was performed and correlated with the reduced penetration of cefuroxime. In two pigs, the levels of oxygen, pyruvate and lactate was estimated in the implant cavity. A peri-implant pathological bone area (PIBA) developed with a width of 1.2 up to 3.8 mm. PIBAs included: (1) suppuration, resulting in destruction of the implant cavity contour, and (2) a non-vascular zone of primarily necrotic bone tissue. A strong negative correlation was seen between PIBA width and cefuroxime area under the concentration time curves (AUC[0-last]) and peak concentration of cefuroxime (Cmax). All metabolic measurements demonstrated hypoxia. In conclusion, subacute suppurative bone inflammation with local tissue destruction can result in decreased penetration of antibiotics and insufficient oxygen supply. PMID- 29169630 TI - Kinetic analysis of canine gait on the effect of failure tendon repair and tendon graft. AB - Kinetic analysis of canine gait has been extensively studied, including normal and abnormal gait. However, no research has looked into how flexor tendon injury and further treatment would affect the walking pattern comparing to the uninjured state. Therefore, this study was aimed to utilize a portable pressure walkway system, which has been commonly used for pedobarographic and kinetic analysis in the veterinary field, to examine the effect of a failed tendon repair and tendon graft reconstruction on canine digit kinetics during gait. 12 mixed breed (mongrel) hound-type female dogs were included in this study and 2nd and 5th digits were chosen to undergo flexor tendon repair and graft surgeries. Kinetic parameters from the surgery leg in stance phase were calculated. From the results, after tendon failure repair, decrease of weight bearing was seen in the affected digits and weight bearing was shifted to the metacarpal pad. After tendon graft reconstruction, weight bearing returned to the affected digits and metacarpal pads. Slight alteration in peak pressure and instant of peak force were identified, but it was estimated to have little influence on post reconstruction gait. This study could serve as a reference in evaluating canine digit function in flexor tendon injury for future studies. PMID- 29169631 TI - Functional MRI can detect changes in intratissue strains in a full thickness and critical sized ovine cartilage defect model. AB - Functional imaging of tissue biomechanics can reveal subtle changes in local softening and stiffening associated with disease or repair, but noninvasive and nondestructive methods to acquire intratissue measures in well-defined animal models are largely lacking. We utilized displacement encoded MRI to measure changes in cartilage deformation following creation of a critical-sized defect in the medial femoral condyle of ovine (sheep) knees, a common in situ and large animal model of tissue damage and repair. We prioritized visualization of local, site-specific variation and changes in displacements and strains following defect placement by measuring spatial maps of intratissue deformation. Custom data smoothing algorithms were developed to minimize propagation of noise in the acquired MRI phase data toward calculated displacement or strain, and to improve strain measures in high aspect ratio tissue regions. Strain magnitudes in the femoral, but not tibial, cartilage dramatically increased in load-bearing and contact regions especially near the defect locations, with an average 6.7% +/- 6.3%, 13.4% +/- 10.0%, and 10.0% +/- 4.9% increase in first and second principal strains, and shear strain, respectively. Strain heterogeneity reflected the complexity of the in situ mechanical environment within the joint, with multiple tissue contacts defining the deformation behavior. This study demonstrates the utility of displacement encoded MRI to detect increased deformation patterns and strain following disruption to the cartilage structure in a clinically-relevant, large animal defect model. It also defines imaging biomarkers based on biomechanical measures, in particular shear strain, that are potentially most sensitive to evaluate damage and repair, and that may additionally translate to humans in future studies. PMID- 29169632 TI - Effects of annular contraction on anterior leaflet strain using an in vitro simulator with a dynamically contracting mitral annulus. AB - Using in vitro models, the mechanics as well as surgical techniques for mitral valves (MV) and MV devices can be studied in a more controlled environment with minimal monetary investment and risk. However, these current models rely on certain simplifications, one being that the MV has a static, rigid annulus. In order to study more complex issues of imaging diagnostics and implanted device function, it would be more advantageous to verify their use for a dynamic environment in a dynamic simulator. This study provides the novel design and development of a dynamically contracting annulus (DCA) within an in vitro simulator, and its subsequent use to study MV biomechanics. Experiments were performed to study the ability of the DCA to reproduce the MV leaflet mechanics in vitro, as seen in vivo, as well as investigate how rigid annuloplasties affect MV leaflet mechanics. Experiments used healthy, excised MVs and normal hemodynamics; contractile waveforms were derived from human in vivo data. Stereophotogrammetry and echocardiography were used to measure anterior leaflet strain and the change in MV geometry. In pursuit of the first in vitro MV simulator that more completely represents the dynamic motion of the full valvular apparatus, this study demonstrated the successful operation of a dynamically contracting mitral annulus. It was seen that the diseased contractile state increased anterior leaflet strain compared to the healthy contractile state. In addition, it was also shown in vitro that simulated rigid annuloplasty increased mitral anterior leaflet strain compared to a healthy contraction. PMID- 29169633 TI - Pathology and genetics of hereditary colorectal cancer. AB - Colorectal cancer (CRC) accounts for over 8% of all deaths annually worldwide. Between 2 and 5% of all CRCs occur due to inherited syndromes, including Lynch syndrome, familial adenomatous polyposis, MUTYH-associated polyposis, Peutz Jeghers syndrome, juvenile polyposis and Cowden/PTEN hamartoma syndrome. In addition, serrated polyposis is a clinically defined condition characterised by multiple colorectal serrated polyps and an increased risk of CRC but the genetics are not known. In most hereditary CRC syndromes, polyps undergo carcinogenesis, but the exact route to carcinoma seems to differ between the conditions. Discovery of the key germline mutations in these syndromes has been instrumental to our understanding of the underlying molecular mechanisms of colorectal carcinogenesis. This review summarises the genetic and pathological alterations in hereditary CRC syndromes. PMID- 29169635 TI - Environmental triggers in systemic lupus erythematosus. AB - Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect almost any organ in the human body. Despite significant advancements in our understanding of SLE over the recent years, its exact mode of onset and disease progression remains elusive. Low concordance rates among monozygotic twins with SLE (as low as 24%), clustering of disease prevalence around polluted regions and an urban-rural difference in prevalence all highlight the importance of environmental influences in SLE. Experimental data strongly suggests a complex interaction between the exposome (or environmental influences) and genome (genetic material) to produce epigenetic changes (epigenome) that can alter the expression of genetic material and lead to development of disease in the susceptible individual. In this review, we focus on the available literature to explore the role of environmental factors in SLE disease onset and progression and to better understand the role of exposome-epigenome-genome interactions in this dreaded disease.

AB - Bipolar disorder (BD) is a leading cause of global disability. Its biological basis is unknown, and its treatment unsatisfactory. Here, we review two recent areas of progress. First, the discovery of risk genes and their implications, with a focus on voltage-gated calcium channels as part of the disease process and as a drug target. Second, facilitated by new technologies, it is increasingly apparent that the bipolar phenotype is more complex and nuanced than simply one of recurring manic and depressive episodes. One such feature is persistent mood instability, and efforts are underway to understand its mechanisms and its therapeutic potential. BD illustrates how psychiatry is being transformed by contemporary neuroscience, genomics, and digital approaches.

AB - A concept of using thin-layer chromatography to multicomponent sample preparation for quantitative determination of solutes followed by instrumental technique is presented. Thin-layer chromatography (TLC) is used to separate chosen substances and their internal standard from other components (matrix) and to form a single spot/zone containing them at the solvent front position. The location of the analytes and internal standard in the solvent front zone allows their easy extraction followed by quantitation by HPLC. PMID- 29169644 TI - Liquid chromatography coupled to tandem mass spectrometry for detecting ten allergens in complex and incurred foodstuffs. AB - Food allergy is a considerable heath problem, as undesirable contaminations by allergens during food production are still widespread and may be dangerous for human health. To protect the population, laboratories need to develop reliable analytical methods in order to detect allergens in various food products. Currently, a large majority of allergen-related food recalls concern bakery products. It is therefore essential to detect allergens in unprocessed and processed foodstuffs. In this study, we developed a method for detecting ten allergens in complex (chocolate, ice cream) and processed (cookie, sauce) foodstuffs, based on ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS). Using a single protocol and considering a signal-to-noise ratio higher than 10 for the most abundant multiple reaction monitoring (MRM) transition, we were able to detect target allergens at 0.5mg/kg for milk proteins, 2.5mg/kg for peanut, hazelnut, pistachio, and cashew proteins, 3mg/kg for egg proteins, and 5mg/kg for soy, almond, walnut, and pecan proteins. The ability of the method to detect 10 allergens with a single protocol in complex and incurred food products makes it an attractive alternative to the ELISA method for routine laboratories. PMID- 29169645 TI - Application of enzymatic probe sonication for selenium speciation in animal feeds. AB - Enzymatic probe sonication (EPS) was investigated as a novel and alternative technology for the extraction of five Se species SeCys2, MeSeCys, Se (IV), SeMet and Se (VI) from animal feeds. The critical parameters of EPS such as enzyme types, ultrasonic power, sample/enzyme ratio, extraction time and temperature were carefully optimized. Under current conditions, one sample can be extracted in 60s, in contrast to several hours required by the conventional enzymatic methods Moreover, the extraction is performed in pure water, no further temperature control or pH adjustment is needed, and therefore the risk of species interconvertion is drastically reduced or inhibited. The Se species were separated and quantitatively determined by high-performance liquid chromatography hydride generation atomic fluorescence spectrometry (HPLC-HG-AFS), which allows the separation of organic and inorganic Se species in a single chromatographic run. The newly developed method was successfully applied to the determination of Se species in 18 feed samples collected from markets and local farms. Concerning the feed samples studied, the results of this work suggest that stricter measures should be taken to control the Se-enriched feed supplements in terms of Se species. PMID- 29169646 TI - Development of an intelligent surgical training system for Thoracentesis. AB - Surgical training improves patient care, helps to reduce surgical risks, increases surgeon's confidence, and thus enhances overall patient safety. Current surgical training systems are more focused on developing technical skills, e.g. dexterity, of the surgeons while lacking the aspects of context-awareness and intra-operative real-time guidance. Context-aware intelligent training systems interpret the current surgical situation and help surgeons to train on surgical tasks. As a prototypical scenario, we chose Thoracentesis procedure in this work. We designed the context-aware software framework using the surgical process model encompassing ontology and production rules, based on the procedure descriptions obtained through textbooks and interviews, and ontology-based and marker-based object recognition, where the system tracked and recognised surgical instruments and materials in surgeon's hands and recognised surgical instruments on the surgical stand. The ontology was validated using annotated surgical videos, where the system identified "Anaesthesia" and "Aspiration" phase with 100% relative frequency and "Penetration" phase with 65% relative frequency. The system tracked surgical swab and 50mL syringe with approximately 88.23% and 100% accuracy in surgeon's hands and recognised surgical instruments with approximately 90% accuracy on the surgical stand. Surgical workflow training with the proposed system showed equivalent results as the traditional mentor-based training regime, thus this work is a step forward a new tool for context awareness and decision making during surgical training.

AB - BACKGROUND: The abnormal alcohol consumption could cause toxicity and could alter the human brain's structure and function, termed as alcohol used disorder (AUD). Unfortunately, the conventional screening methods for AUD patients are subjective and manual. Hence, to perform automatic screening of AUD patients, objective methods are needed. The electroencephalographic (EEG) data have been utilized to study the differences of brain signals between alcoholics and healthy controls that could further developed as an automatic screening tool for alcoholics. METHOD: In this work, resting-state EEG-derived features were utilized as input data to the proposed feature selection and classification method. The aim was to perform automatic classification of AUD patients and healthy controls. The validation of the proposed method involved real-EEG data acquired from 30 AUD patients and 30 age-matched healthy controls. The resting-state EEG-derived features such as synchronization likelihood (SL) were computed involving 19 scalp locations resulted into 513 features. Furthermore, the features were rank-ordered to select the most discriminant features involving a rank-based feature selection method according to a criterion, i.e., receiver operating characteristics (ROC). Consequently, a reduced set of most discriminant features was identified and utilized further during classification of AUD patients and healthy controls. In this study, three different classification models such as Support Vector Machine (SVM), Naive Bayesian (NB), and Logistic Regression (LR) were used. RESULTS: The study resulted into SVM classification accuracy=98%, sensitivity=99.9%, specificity=95%, and f-measure=0.97; LR classification accuracy=91.7%, sensitivity=86.66%, specificity=96.6%, and f-measure=0.90; NB classification accuracy=93.6%, sensitivity=100%, specificity=87.9%, and f-measure=0.95. CONCLUSION: The SL features could be utilized as objective markers to screen the AUD patients and healthy controls.

AB - Despite great improvements in the outcome of patients with lymphoma, some may still relapse or present with primary refractory disease. In these situations, allogeneic haematopoietic cell transplantation (allo-HCT) is a potentially curative option, in particular in the case of relapse after autologous stem cell transplantation. Recently, novel agents such as anti-PD1 and BTK inhibitors have started to challenge the use of allo-HCT for relapsed or refractory lymphoma. During the 2016 annual workshop of the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC), we performed a comprehensive review of the literature published in the last 10 years and established guidelines to clarify the indications and transplant modalities in this setting. This manuscript reports on general considerations regarding allo-HCT for lymphoma and elaborates on the use of alternative donors in this setting.

AB - Delivery of neuropeptide Y (NPY) to the brain by intranasal administration shows promise as non-invasive means for preventing or treating PTSD symptoms. Here, radiotelemetry and echocardiography were used to determine effects of intranasal NPY on cardiovascular functions in absence and presence of stress. Male adult Sprague Dawley rats were implanted with radiotelemetric probes, and subjected to single prolonged stress (SPS), followed by intranasal vehicle (V) or NPY (150MUg) under conditions shown to prevent development of many of the behavioral neuroendocrine and biochemical impairments. In both groups, mean arterial pressure (MAP) rose rapidly peaking at about 125mmHg, remaining near maximal levels for 1h. SPS also elicited robust rise in heart rate (HR) which was mitigated by intranasal NPY, and significantly lower than V-treated rats 12-50min after exposure to SPS stressors. In the first hr. after SPS, locomotor activity was elevated but only in the V-treated group. By 3h, MAP returned to pre-stress levels in both groups with no further change when monitored for 6days. HR remained elevated during the 6h remaining light phase after SPS. Subsequently HR was at pre-SPS levels during the remaining days. However dark phase HR was low following SPS, gradually recovered over 6days and was associated with reduced activity. When administered in the absence of further stress, intranasal NPY or V elicited similar much smaller, short-lived rises in MAP and HR. Echocardiography revealed no change in HR, stroke volume (SV) or cardiac output (Q) with intranasal NPY in the absence of stress. SPS led to reduced SV and Q but was not affected by NPY. Overall the results demonstrate no major cardiovascular effects of intranasal NPY and indicate possible benefit from transient amelioration of HR response in line with its translational potential to combat PTSD and comorbid impairments.

AB - BACKGROUND: Symmetric peripheral gangrene (SPG) is a symmetrical distal ischemic lesion on at least 2 or more extremities in the absence of proximal arterial obstruction and vasculitis. It is a rare and severe clinical entity. The aim of this study was to describe clinical symptoms, etiological agents and the management of SPG through a series of 4 cases. PATIENTS AND METHODS: We included all cases of SPG hospitalized between 2000 and 2014. The inclusion criterion was the presence of distal ischemic damage at two or more sites in the absence of large vessel obstruction. RESULTS: Four patients (2 men and 2 women) were included. The mean age was 43.2+/-12 years. Two patients had a history of splenectomy. All patients had blackening of the tips of the fingers and toes. Three patients presented with septic shock. The etiology was bacteremia involving Streptococcus pneumoniae in two cases and a malignant form of Mediterranean spotted fever (MSF). In addition to specific antibiotics, we used a potent vasodilator (iloprost) in two cases and curative heparin therapy in two cases. The outcome was favorable in 3 cases, with regression of necrotic lesions. One case required the amputation of non-perfused necrotic fingers and toes. CONCLUSION: SPG can complicate MSF in some rare cases. Thorough and repeated skin examinations are essential to ensure timely diagnosis and treatment of GPS in order to improve the prognosis.

PMID- 29169660 TI - Reward and loss anticipation in panic disorder: An fMRI study. AB - Anticipatory anxiety and harm avoidance are essential features of panic disorder (PD) and may involve deficits in the reward system of the brain, in particular in the ventral striatum. While neuroimaging studies on PD have focused on fearful and negative affective stimulus processing, no investigations have directly addressed deficits in reward and loss anticipation. To determine whether the ventral striatum shows abnormal neural activity in PD patients during anticipation of loss or gain, an event-related functional magnetic resonance imaging experiment using a monetary incentive delay task was employed in 10 patients with PD and 10 healthy controls. A repeated-measures ANOVA to identify effects of group (PD vs. Control) and condition (anticipation of loss vs. gain vs. neutral outcome) revealed that patients with PD showed significantly reduced bilateral ventral striatal activation during reward anticipation but increased activity during loss anticipation. Within the patient group, the degree of activation in the ventral striatum during loss-anticipation was positively correlated with harm avoidance and negatively correlated with novelty seeking. These findings suggest that behavioural impairments in panic disorder may be related to abnormal neural processing of motivational cues. PMID- 29169661 TI - Light irradiance through novel CAD-CAM block materials and degree of conversion of composite cements. AB - OBJECTIVE: To assess light irradiance (LI) delivered by two light-curing units (LCU's) and to measure the degree of conversion (DC) of three composite cements, when cured through different thicknesses of two novel CAD-CAM block materials. METHODS: 100-MUm-thick films of a dual-curable composite cement (G-CEM LinkAce, GC), a light-curable flowable resin-based composite (RBC) (G-aenial Universal Flo, GC) and a micro-hybrid RBC (G-aenial Posterior, GC) were investigated as luting agents. Two 'polymer-ceramic' CAD-CAM blocks (Cerasmart, GC; Enamic, Vita Zahnfabrik) were sectioned in slabs with different thicknesses (1, 3 and 5mm). LI at the bottom of the specimens was measured using a calibrated spectrometer, while being light-cured through the CAD-CAM block slabs for 40s with a low- (+/ 500mW/cm2) or high- (+/-1,600mW/cm2) irradiance LCU (n=5). After light-curing, micro-Raman spectra of the composite films were acquired to determine DC at 5min, 10min, 1h and 24h. LI data were statistically analyzed by Kruskal-Wallis followed by post-hoc comparisons, while a linear mixed-effect model was applied for the DC analysis. In addition, the CAD-CAM blocks ultrastructure was characterized upon argon-ion slicing using scanning transmission electron microscopy (STEM). Finally, light transmission (LT) through each CAD-CAM block material was assessed using a spectrophotometer. RESULTS: Curing-light attenuation and DC were significantly influenced by thickness and type of the overlying material. LCU only had a significant effect on DC of the micro-hybrid RBC. DC significantly increased over time for all composite cements. CAD-CAM block structural analysis revealed a relatively small and homogenous filler configuration (mean filler size of 0.2-0.5MUm) for Cerasmart, while Enamic contained ceramic grains varying in shape and size (1-10MUm), which were interconnected by the polymer-based network. LT was much higher at a wavelength range of 300-800nm for Cerasmart than for Enamic. SIGNIFICANCE: Light-curable composite cements can be cured through a restoration up to 2.7-mm thickness, depending on the kind of CAD-CAM material. A high-irradiance LCU only has a limited effect on the maximum thickness of the polymer-ceramic CAD-CAM material that can be cured through. PMID- 29169662 TI - Effects of Contrast Enhancement on In-Body Calibrated Phantomless Bone Mineral Density Measurements in Computed Tomography. AB - We aimed to test the potential of phantomless volumetric bone mineral density (PLvBMD) measurements for the determination of volumetric bone mineral density (vBMD) in routine contrast-enhanced computed tomography (CECT). We evaluated 56 tri-phasic abdominal computed tomography scans, including an unenhanced scan as well as defined CECT scans in the arterial and portalvenous phase. PLvBMD analysis was performed by 4 radiologists using an FDA-approved tool for phantomless evaluation of bone density (IntelliSpace, Philips, The Netherlands). Mean vBMD of the first 3 lumbar vertebrae in each contrast phase was determined and interobserver variance of vBMD independent of contrast phase was analyzed using intraclass correlation, Bland-Altman plots, and Student's t test. CECT scans were associated with a significantly higher PLvBMD compared with unenhanced scans (unenhanced computed tomography: 97.8 mg/cc; arterial CECT: 106.3 mg/cc, portalvenous CECT: 106.3 mg/cc). Overall, there was no significant difference of PLvBMD between data acquisition in arterial and portalvenous phases (increase of 8.6% each, standard deviation ratio 37.7%-38.3%). In Bland-Altman analysis, there was no evidence of a relevant reader-related bias or an increase in standard deviation of PLvBMD measurements in contrast-enhanced scans compared with unenhanced scans. The following conversion formulas for unenhanced PLvBMD were determined: unenhancedPLvBMD=0.89*arterialPLvBMD+3,74mg/cc(r2 = 0.94) and unenhancedPLvBMD=0.88*venousPLvBMD+4,56mg/cc(r2 = 0.93). Compared with the results of phantom-based quantitative computed tomography measurements reported in the literature, the PLvBMD changes associated with contrast enhancement were relatively moderate with an increase of 8.6% in average. The time-point of the contrast-enhanced PLvBMD measurements after injection of contrast media did not appear to affect the results. With the adjustment formulas provided in this study, the method can improve osteoporosis screening through detection of reduced bone mass of the vertebrae in routinely conducted CECT. PMID- 29169663 TI - Polysialylated Neural Cell Adhesion Molecule Supports Regeneration of Neurons in the Nucleus Ambiguus After Unilateral Recurrent Laryngeal Nerve Avulsion in Adult Rats. AB - OBJECTIVES: A correlation appears to exist between the expression of the polysialic acid neural cell adhesion molecule (PSA-NCAM) and repair in central nervous system (CNS) diseases. However, the expression of PSA-NCAM in the CNS after peripheral nerve injury remains unclear. This study aimed to evaluate the expression of PSA-NCAM in the ipsilateral nucleus ambiguus (NA) after unilateral recurrent laryngeal nerve (RLN) avulsion. MATERIALS AND METHODS: The left RLN of adult Sprague Dawley rats were avulsed. The expression of PSA-NCAM, PSA NCAM/NeuN, and PSA-NCAM/Tuj1 in the brain stem was investigated using immunohistochemistry. The results were subjected to one-way analysis of variance followed by the Tukey post hoc test for statistical analyses. RESULTS: PSA-NCAM positive and PSA-NCAM/NeuN and PSA-NCAM/Tuj1 double-labeled positive cells were observed 7 days post injury in the ipsilateral NA. PSA-NCAM/NeuN and PSA NCAM/Tuj1 double-labeled cells were observed at 21 and 7 days post injury, respectively. PSA-NCAM/NeuN double-labeled cells were also found in the contralateral NA. CONCLUSIONS: After unilateral avulsion of the RLN, the expression of PSA-NCAM in the ipsilateral NA was correlated with the proliferation and the differentiation of neural cells. PSA-NCAM expression may be used as a predictor of the initiation of repair in neural cells. PMID- 29169665 TI - Mindfulness and craving: effects and mechanisms. AB - Mindfulness meditation has a long tradition of being used to manage cravings. This paper reviews 30 experimental studies that have examined the effects of different types of mindfulness practice on cravings for food, cigarettes and alcohol. The findings are interpreted in light of relevant theories of craving. The studies show most support for the elaborated intrusion theory of desire and conditioning models. They suggest that whilst mindfulness strategies may bring about immediate reductions in craving, such effects are likely to stem from working memory load, and will not necessarily be superior to alternative strategies that also load working memory. Likewise, reductions in craving over the medium term may occur due to extinction processes that result from the individual inhibiting craving-related responses. Again, alternative strategies that promote response suppression may be equally effective. Nevertheless, a smaller number of studies show promising results where mindfulness exercises have been repeatedly practiced over a longer period of time. The results of these studies provide tentative support for Buddhist models of craving that suggest mindfulness practice may confer unique benefits in terms of both craving reduction and reducing the extent to which craving leads to consumption. Further research would be needed to confirm this. PMID- 29169664 TI - Long-term efficacy of psychotherapy for posttraumatic stress disorder: A meta analysis of randomized controlled trials. AB - Psychotherapies are well established as efficacious acute interventions for posttraumatic stress disorder (PTSD). However, the long-term efficacy of such interventions and the maintenance of gains following termination is less understood. This meta-analysis evaluated enduring effects of psychotherapy for PTSD in randomized controlled trials (RCTs) with long-term follow-ups (LTFUs) of at least six months duration. Analyses included 32 PTSD trials involving 72 treatment conditions (N=2935). Effect sizes were significantly larger for active psychotherapy conditions relative to control conditions for the period from pretreatment to LTFU, but not posttreatment to LTFU. All active interventions demonstrated long-term efficacy. Pretreatment to LTFU effect sizes did not significantly differ among treatment types. Exposure-based treatments demonstrated stronger effects in the posttreatment to LTFU period (d=0.27) compared to other interventions (p=0.005). Among active conditions, LTFU effect sizes were not significantly linked to trauma type, population type, or intended duration of treatment, but were strongly tied to acute dropout as well as whether studies included all randomized patients in follow-up analyses. Findings provide encouraging implications regarding the long-term efficacy of interventions and the durability of symptom reduction, but must be interpreted in parallel with methodological considerations and study characteristics of RCTs.

PMID- 29169670 TI - Are patients satisfied with the head and neck skin cancer service? An evaluation of outpatient services with a review of published reports. AB - Scientific publications place much emphasis on postoperative outcomes such as recurrence, but little attention to patients' satisfaction. The purpose of this evaluation was to find out patients' reported outcomes after their initial consultation, treatment, and follow-up appointments for non-melanoma skin cancer of the head and neck. We used an adapted version of the European Organisation for Research and Treatment of Cancer (EORTC) validated questionnaire for patients' satisfaction to collect data prospectively from consenting patients between September and December 2015. A total of 179 questionnaires were completed (initial consultation n=51, treatment n=74, and follow up n=54). Patients were most satisfied with the appointments for treatment (Kruskal-Wallis p<0.001, mean (SD) score 4.86/5 (0.15)), and 87% regarding the service as excellent. Patients were least satisfied with services and organisation of care compared with nurses and doctors (Kruskal-Wallis p<0.001). There seemed to be most satisfaction after the appointment for treatment. A possible explanation could simply be the relief of having finally had their cancer removed. Patients are also likely to show greater satisfaction with the clinical team because of the personal nature of the interaction that they experience during this aspect of their care. PMID- 29169668 TI - Arthroscopic subacromial decompression for subacromial shoulder pain (CSAW): a multicentre, pragmatic, parallel group, placebo-controlled, three-group, randomised surgical trial. AB - BACKGROUND: Arthroscopic sub-acromial decompression (decompressing the sub acromial space by removing bone spurs and soft tissue arthroscopically) is a common surgery for subacromial shoulder pain, but its effectiveness is uncertain. We did a study to assess its effectiveness and to investigate the mechanism for surgical decompression. METHODS: We did a multicentre, randomised, pragmatic, parallel group, placebo-controlled, three-group trial at 32 hospitals in the UK with 51 surgeons. Participants were patients who had subacromial pain for at least 3 months with intact rotator cuff tendons, were eligible for arthroscopic surgery, and had previously completed a non-operative management programme that included exercise therapy and at least one steroid injection. Exclusion criteria included a full-thickness torn rotator cuff. We randomly assigned participants (1:1:1) to arthroscopic subacromial decompression, investigational arthroscopy only, or no treatment (attendance of one reassessment appointment with a specialist shoulder clinician 3 months after study entry, but no intervention). Arthroscopy only was a placebo as the essential surgical element (bone and soft tissue removal) was omitted. We did the randomisation with a computer-generated minimisation system. In the surgical intervention groups, patients were not told which type of surgery they were receiving (to ensure masking). Patients were followed up at 6 months and 1 year after randomisation; surgeons coordinated their waiting lists to schedule surgeries as close as possible to randomisation. The primary outcome was the Oxford Shoulder Score (0 [worst] to 48 [best]) at 6 months, analysed by intention to treat. The sample size calculation was based upon a target difference of 4.5 points (SD 9.0). This trial has been registered at ClinicalTrials.gov, number NCT01623011. FINDINGS: Between Sept 14, 2012, and June 16, 2015, we randomly assigned 313 patients to treatment groups (106 to decompression surgery, 103 to arthroscopy only, and 104 to no treatment). 24 [23%], 43 [42%], and 12 [12%] of the decompression, arthroscopy only, and no treatment groups, respectively, did not receive their assigned treatment by 6 months. At 6 months, data for the Oxford Shoulder Score were available for 90 patients assigned to decompression, 94 to arthroscopy, and 90 to no treatment. Mean Oxford Shoulder Score did not differ between the two surgical groups at 6 months (decompression mean 32.7 points [SD 11.6] vs arthroscopy mean 34.2 points [9.2]; mean difference -1.3 points (95% CI -3.9 to 1.3, p=0.3141). Both surgical groups showed a small benefit over no treatment (mean 29.4 points [SD 11.9], mean difference vs decompression 2.8 points [95% CI 0.5-5.2], p=0.0186; mean difference vs arthroscopy 4.2 [1.8-6.6], p=0.0014) but these differences were not clinically important. There were six study-related complications that were all frozen shoulders (in two patients in each group). INTERPRETATION: Surgical groups had better outcomes for shoulder pain and function compared with no treatment but this difference was not clinically important. Additionally, surgical decompression appeared to offer no extra benefit over arthroscopy only. The difference between the surgical groups and no treatment might be the result of, for instance, a placebo effect or postoperative physiotherapy. The findings question the value of this operation for these indications, and this should be communicated to patients during the shared treatment decision-making process.

PMID- 29169671 TI - Enhanced recovery in patients having free tissue transfer for head and neck cancer: does it make a difference? AB - Programmes for Enhanced Recovery after Surgery (ERAS) accelerate recovery, reduce morbidity, and shorten hospital stay in a wide range of surgical specialties. We established a standardised multimodal ERAS pathway for patients who were being treated by free tissue transfer for head and neck cancer to evaluate its benefit. Our primary outcome was duration of hospital stay, and secondary outcomes included complications, number of days to first mobilisation, and readmission rates. We compared 100 consecutive patients who followed the ERAS programme with a control group of 40 consecutive patients who had free tissue transfer before the ERAS programme was introduced. There was a significantly reduced median duration of stay from 14days in the control group to 10days in the ERAS group. Patients in the ERAS group who were aged over 60 years, or had tracheostomies, or who required bone resection also had a significantly reduced duration of stay. There was no difference between morbidity and readmission rates, although patients in the ERAS group were mobilised significantly earlier. The ERAS programme is safe and effective for patients who are treated by free tissue transfer for head and neck cancer, and potentially reduces their duration of stay in hospital.

AB - Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract and may occasionally present with acute gastrointestinal bleed (GIB). Multidetector computed tomography (MDCT) angiography is extremely useful in demonstrating the tumor as well as the presence of active hemorrhage, thereby guiding subsequent interventional or surgical management. We report a case of a 38-year-old man who presented with acute-onset melena and compensated shock, whose source of bleed remained elusive on endoscopy. MDCT angiography performed on a dual-energy scanner showed a jejunal tumor with active intraluminal contrast extravasation. The tumor was subsequently resected and the patient did well on follow-up. This was one of the few instances when MDCT angiography demonstrated active bleeding in a GIST and the first such case demonstrated on a dual-energy scanner.

AB - Programmed death receptor 1 (PD1) checkpoint inhibitors are known for immune mediated toxicities such as colitis, endocrinopathies and pneumonitis. However, other rare adverse effects are reported in the literature. Nivolumab is an anti PD1 immunotherapy used in the second line of non-small cell lung cancer (NSCLC). We report two cases of rare toxicities occurring under nivolumab in patients without a history of dysimmunity. A 79-year-old patient with a large-cell carcinoma showed a muscle weakness after the second course, revealing myositis with a CPK grade IV elevation as well as symptoms of myasthenia. The diagnosis of myositis was confirmed by a muscle biopsy. An 82-year-old patient followed for bronchial adenocarcinoma with EGFR mutation, presented with nivolumab shoulder and hip pain with extreme fatigue. After further investigations, the diagnosis of systemic erythematosus lupus was retained. Investigations led to the diagnosis of systemic lupus erythematosus. For both patients treatment was interrupted and systemic corticosteroid therapy was initiated permitting resolution of symptoms. The occurrence of symptoms of dysimmunity should attract the attention of the clinician, leading to discontinuation of anti-PD1 therapy and corticosteroid therapy. Retreatment after symptoms resolution must be collegially discussed if no alternative therapeutic is available.

PMID- 29169679 TI - Assessing the accuracy of body mass estimation equations from pelvic and femoral variables among modern British women of known mass. AB - Femoral head diameter is commonly used to estimate body mass from the skeleton. The three most frequently employed methods, designed by Ruff, Grine, and McHenry, were developed using different populations to address different research questions. They were not specifically designed for application to female remains, and their accuracy for this purpose has rarely been assessed or compared in living populations. This study analyzes the accuracy of these methods using a sample of modern British women through the use of pelvic CT scans (n = 97) and corresponding information about the individuals' known height and weight. Results showed that all methods provided reasonably accurate body mass estimates (average percent prediction errors under 20%) for the normal weight and overweight subsamples, but were inaccurate for the obese and underweight subsamples (average percent prediction errors over 20%). When women of all body mass categories were combined, the methods provided reasonable estimates (average percent prediction errors between 16 and 18%). The results demonstrate that different methods provide more accurate results within specific body mass index (BMI) ranges. The McHenry Equation provided the most accurate estimation for women of small body size, while the original Ruff Equation is most likely to be accurate if the individual was obese or severely obese. The refined Ruff Equation was the most accurate predictor of body mass on average for the entire sample, indicating that it should be utilized when there is no knowledge of the individual's body size or if the individual is assumed to be of a normal body size. The study also revealed a correlation between pubis length and body mass, and an equation for body mass estimation using pubis length was accurate in a dummy sample, suggesting that pubis length can also be used to acquire reliable body mass estimates. This has implications for how we interpret body mass in fossil hominins and has particular relevance to the interpretation of the long pubic ramus that is characteristic of Neandertals.

AB - In this paper, we present pounded objects from excavations at HWK EE and EF-HR, which are studied from macro and microscopic perspectives. Analysis of HWK EE revealed one of the largest collections of percussive objects from Olduvai Gorge, while excavations at EF-HR have allowed us to recover a much wider collection of percussive tools than previously recorded. Differences are observed between the two localities. At the Acheulean site of EF-HR, percussive tools were predominantly used in the production of flakes and large cutting tools (LCTs). At the Oldowan site of HWK EE, the tool repertoire probably related to a wider range of activities, including bone breaking and bipolar knapping. Comparison of these two assemblages, potentially produced by different hominin species, helps provide a wider picture of pounding activities during the Oldowan-Acheulean transition at Olduvai Gorge.

AB - In the hominin fossil record, pelvic remains are sparse and are difficult to attribute taxonomically when they are not directly associated with craniodental material. Here we describe the pelvic remains from the Dinaledi Chamber in the Rising Star cave system, Cradle of Humankind, South Africa, which has produced hominin fossils of a new species, Homo naledi. Though this species has been attributed to Homo based on cranial and lower limb morphology, the morphology of some of the fragmentary pelvic remains recovered align more closely with specimens attributed to the species Australopithecus afarensis and Australopithecus africanus than they do with those of most (but not all) known species of the genus Homo. As with A. afarensis and A. africanus, H. naledi appears to have had marked lateral iliac flare and either a weakly developed or non-existent acetabulocristal buttress or a distinct, albeit weakly developed, acetabulospinous buttress. At the same time, H. naledi has robust superior pubic and ischiopubic rami and a short ischium with a narrow tuberoacetabular sulcus, similar to those found in modern humans. The fragmentary nature of the Dinaledi pelvic assemblage makes the attribution of sex and developmental age to individual specimens difficult, which in turn diminishes our ability to identify the number of individuals represented in the assemblage. At present, we can only confidently say that the pelvic fossils from Rising Star represent at least four individuals based on the presence of four overlapping right ischial fossils (whereas a minimum of 15 individuals can be identified from the Dinaledi dental assemblage). A primitive, early Australopithecus-like false pelvis combined with a derived Homo-like true pelvis is morphologically consistent with evidence from the lower ribcage and proximal femur of H. naledi. The overall similarity of H. naledi ilia to those of australopiths supports the inference, drawn from the observation of primitive pelvic morphology in the extinct species Homo floresiensis, that there is substantial variation in pelvic form within the genus Homo. In the light of these findings, we urge caution in making taxonomic attributions-even at the genus level-of isolated fossil ossa coxae.

AB - The application of apheresis equipment to perform leukapheresis (LK) in low weight paediatric patients is logistically complex and lacking of largest clinical performing experiences, meanwhile, the benefit from LK is controversial. In this study, 15 children with acute lymphoblastic leukemia(ALL)and acute myeloid leukemia (AML) and hyperleukocytosis were treated with the COBE Spectra apheresis system in the general paediatric ward by the staff from the department of Blood Transfusion. 26 LK procedures were performed. 12 patients (80%) were performed with peripheral veins, others (20%) with femoral veins. Median age, body weight of the patients was 4 years (range from1year 10 month to 7 years) and 15kg (range from10 to 20kg). The median white blood cell (WBC) count of pre-first LK was 289*109/L (range from 108*109/L to 579*109/L). The median decrease in WBC count after each LK was 34% (range from 14% to 54%), and overall decrease in WBC after completion of LK procedures was 45% (range from 15% to 70%). All of the patients had no further signs of leukostasis and achieved marked reductions in WBC counts. Only minor clinical adverse events were attributable to LK. With adequate monitoring and experienced team, LK is a safe and may be a beneficial leukoreduction method in small patients weighing 20kg or less with ALL and AML. PMID- 29169684 TI - Airway morphology and inspiratory flow features in the early stages of Chronic Obstructive Pulmonary Disease. AB - BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is among the leading causes of death worldwide. Inhaled pollutants are the prime risk factor, but the pathogenesis and progression of the diseased is poorly understood. Most studies on the disease onset and trajectory have focused on genetic and molecular biomarkers. Here we investigate the role of the airway anatomy and the consequent respiratory fluid mechanics on the development of COPD. METHODS: We segmented CT scans from a five-year longitudinal study in three groups of smokers (18 subjects each) having: (i) minimal/mild obstruction at baseline with declining lung function at year five; (ii) minimal/mild obstruction at baseline with stable function, and (iii) normal and stable lung function over the five year period. We reconstructed the bronchial trees up to the 7th generation, and for one subject in each group we performed MRI velocimetry in 3D printed models. FINDINGS: The subjects with airflow obstruction at baseline have smaller airway diameters, smaller child-to-parent diameter ratios, larger length-to-diameter ratios, and smaller fractal dimensions. The differences are more significant for subjects that develop severe decline in pulmonary function. The secondary flows that characterize lateral dispersion along the airways are found to be less intense in the subjects with airflow obstruction. INTERPRETATION: These results indicate that morphology of the conducting airways and inspiratory flow features are correlated with the status and progression of COPD already at an early stage of the disease. This suggests that imaging-based biomarkers may allow a pre symptomatic diagnosis of disease progression. PMID- 29169685 TI - Surveillance of porcine reproductive and respiratory syndrome virus in the United States using risk mapping and species distribution modeling. AB - Porcine reproductive and respiratory syndrome virus (PRRSv) outbreaks cause significant financial losses to the U.S. swine industry, where the pathogen is endemic. Seasonal increases in the number of outbreaks are typically observed using PRRSv epidemic curves. However, the nature and extent to which demographic and environmental factors influence the risk for PRRSv outbreaks in the country remains unclear. The objective of this study was to develop risk maps for PRRSv outbreaks across the United States (U.S.) and compare ecological dynamics of the disease in five of the most important swine production regions of the country. This study integrates spatial information regarding PRRSv surveillance with relevant demographic and environmental factors collected between 2009 and 2016. We used presence-only Maximum Entropy (Maxent), a species distribution modeling approach, to model the spatial risk of PRRSv in swine populations. Data fitted the selected model relatively well when the modeling approach was conducted by region (training and testing AUCs<0.75). All of the Maxent models selected identified high-risk areas, with probabilities greater than 0.5. The relative contribution of pig density to PRRSv risk was highest in pig-densely populated areas (Minnesota, Iowa and North Carolina), whereas climate and land cover were important in areas with relatively low pig densities (Illinois, Indiana, South Dakota, Nebraska, Kansas, Oklahoma, Colorado, and Texas). Although many previous studies associated the risk of PRRSv with high pig density and climatic factors, the study here quantifies, for the first time in the peer-reviewed literature, the spatial variation and relative contribution of these factors across different swine production regions in the U.S. The results will help in the design and implement of early detection, prevention, and control strategies for one of the most devastating diseases affecting the swine industry in the U.S. PMID- 29169686 TI - Diagnosing intramammary infection: Controlling misclassification bias in longitudinal udder health studies. AB - Using imperfect tests may lead to biased estimates of disease frequency and of associations between risk factors and disease. For instance in longitudinal udder health studies, both quarters at risk and incident intramammary infections (IMI) can be wrongly identified, resulting in selection and misclassification bias, respectively. Diagnostic accuracy can possibly be improved by using duplicate or triplicate samples for identifying quarters at risk and, subsequently, incident IMI. The objectives of this study were to evaluate the relative impact of selection and misclassification biases resulting from IMI misclassification on measures of disease frequency (incidence) and of association with hypothetical exposures. The effect of improving the sampling strategy by collecting duplicate or triplicate samples at first or second sampling was also assessed. Data sets from a hypothetical cohort study were simulated and analyzed based on a separate scenario for two common mastitis pathogens representing two distinct prevailing patterns. Staphylococcus aureus, a relatively uncommon pathogen with a low incidence, is identified with excellent sensitivity and almost perfect specificity. Coagulase negative staphylococci (CNS) are more prevalent, with a high incidence, and with milk bacteriological culture having fair Se but excellent Sp. The generated data sets for each scenario were emulating a longitudinal cohort study with two milk samples collected one month apart from each quarter of a random sample of 30 cows/herd, from 100 herds, with a herd level exposure having a known strength of association. Incidence of IMI and measure of association with exposure (odds ratio; OR) were estimated using Markov Chain Monte Carlo (MCMC) for each data set and using different sampling strategies (single, duplicate, triplicate samples with series or parallel interpretation) for identifying quarters at risk and incident IMI. For S. aureus biases were small with an observed incidence of 0.29 versus a true incidence of 0.25IMI/100 quarter-month. In the CNS scenario, diagnostic errors in the two samples led to important selection (40IMI/100 quarter-month) and misclassification (23IMI/100 quarter-month) biases for estimation of IMI incidence, respectively. These biases were in opposite direction and therefore the incidence measure obtained using single sampling on both the first and second test (29IMI/100 quarter-month) was exactly the true value. In the S. aureus scenario the OR for association with exposure showed little bias (observed OR of 3.1 versus true OR of 3.2). The CNS scenario revealed the presence of a large misclassification bias moving the association towards the null value (OR of 1.7 versus true OR of 2.6). Little improvement could be brought using different sampling strategies aiming at improving Se and/or Sp on first and/or second sampling or using a two out of three interpretation for IMI definition. Increasing number of samples or tests can prevent bias in some situations but efforts can be spared by holding to a single sampling approach in others. When designing longitudinal studies, evaluating potential biases and best sampling strategy is as critical as the choice of test. PMID- 29169687 TI - Understanding the inhibitory mechanism of BIT225 drug against p7 viroporin using computational study. AB - P7 is the only viral channel encoded by the Hepatitis C Virus (HCV) genome. It is a small, highly hydrophobic protein containing 63 amino acids. Structural studies have shown that p7 has two transmembrane (TM) alpha helices linked by a short dibasic cytoplasmic loop. P7, mostly placed in the endoplasmic reticulum (ER), is a membrane-associated protein. The results obtained from different studies revealed that p7 is a polytopic membrane protein that could oligomerize in membrane bilayer to create ion channels with cation selectivity. In addition, p7 is highly conserved and plays an important role in the assembly and release of mature viral particles. Thus, it can be considered as a potential target for anti HCV drugs. It has been found that several compounds (amantadine, rimantadine, hexamethylene amiloride (HMA) and long-alkyl-chain iminosugar (IS) derivatives) inhibit p7 channel ability. Another new inhibitor identified as BIT225, a derivative of amiloride, also inhibits the viroporin function of HIV-1 Vpu and HCV p7. In the present study, molecular dynamics simulations were applied to get insights into molecular details of a BIT225 binding site. In addition, the g_mmpbsa approach was employed to calculate the binding free energy and free energy decomposition per residue. MD simulation results in the p7-BIT225 complex revealed that drug binding to hydrophobic pocket can allosterically inhibit ion conduction via the funnel tip by restricting significant intrinsic channel breath at the tip of the funnel. Based on the molecular dynamics simulation (MD) analysis and the energy profiles, the hydrophobic interactions were the main driving force for BIT225 binding.

AB - BACKGROUND: Although patient-reported outcomes measures (PROMs) provide valuable health information and aid medical decision making for patients with hip and knee arthritis, survey completion rates remain low. The purpose of this study is to elucidate patient preferences regarding location of completion, delivery method, and barriers or facilitators to pre-visit completion. METHODS: Patients with hip and/or knee pain who were asked to complete pre-visit PROMs at 2 urban arthroplasty clinics were recruited. In-person, semi-structured, audio-recorded interviews were conducted, transcribed, and coded for thematic analysis. Codes were developed using a data-driven approach. RESULTS: We analyzed 51 interviews. The mean age was 57 years, 57% were women, and 45% had private or Medicare insurance. Prevalent themes regarding location preferences were convenience and communication preferences. Thirty-four patients stated a preference for completing pre-visit PROMs at home, 19 for in-office completion, and 10 stated no preference. Prevalent themes around delivery methods included technology access and familiarity. Of the 43 patients asked to select their preferred pre-visit PROM delivery method (phone call, email, text message, or postal mail), 31 (72%) preferred email or text messaging. Barriers to completing pre-visit PROMs were technological issues, recognizing the message was healthcare-related, and being too busy or forgetting. Twenty patients identified no barriers. CONCLUSION: Electronic PROM collection is favored by many patients, but alternative methods for patients without access to or familiarity with technology remain important. Clear recognition that the message is from a physician's office and physician communication of the utility of PROMs in clinical decision making may increase pre-visit completion. PMID- 29169690 TI - Evaluation of Surface Finish and Dimensional Control of Tribological Metal-Ultra High Molecular Weight Polyethylene Pair of Commercially Available Hip Implants. AB - BACKGROUND: Dimensional control and surface finish of the femoral head and acetabular liner are critical factors in the manufacturing process due to the risk of increased polyethylene wear, which is the primary cause of aseptic failure of a metal/polymer hip prosthesis. The aim of this study is to perform a dimensional and surface finish analysis to evaluate the reproduction and accuracy of the manufacturing processes of metal femoral heads and ultra high molecular weight polyethylene acetabular liners. METHODS: Four femoral heads and acetabular liners from 5 manufacturers were evaluated. The methods of evaluation followed the standards ISO 7206-2:2011 and ISO 21535:2010. RESULTS: The diameter, sphericity, and roughness of the femoral heads from all the manufacturers were in accordance with the standard requirements. Only the sphericity showed a lack of repeatability among the manufacturers. The variability in sphericity was high among some manufacturers and low in others. The diameters of the acetabular liners of 2 manufacturers were not in accordance with the standard requirements. The repeatability of sphericity, thickness, and roughness of the acetabular liners were heterogeneous among the manufacturers, which means that some manufacturers need to improve quality control. CONCLUSION: Our results showed a good dimensional and surface finish control of the manufacturing processes of the femoral heads. However, the same control was not shown during the manufacturing of the acetabular liners although all samples had a thickness and sphericity in accordance with the standard. A better quality control of the manufacturing process of ultra high molecular weight polyethylene acetabular liners should be made to improve the dimensional parameters of the acetabular liners and the tribological pair. PMID- 29169691 TI - Kocuria uropygioeca sp. nov. and Kocuria uropygialis sp. nov., isolated from the preen glands of Great Spotted Woodpeckers (Dendrocopos major). AB - Two new species of Gram-positive cocci were isolated from the uropygial glands of wild woodpeckers (Dendrocopos major) originating from different locations in Germany. A polyphasic approach confirmed the affiliation of the isolates to the genus Kocuria. Phylogenetic analysis based on the 16S rRNA gene showed high degree of similarity to Kocuria koreensis DSM 23367T (99.0% for both isolates). However, low ANIb values of <80% unequivocally separated the new species from K. koreensis. This finding was further corroborated by DNA fingerprinting and analysis of polar lipid profiles. Furthermore, growth characteristics, biochemical tests, MALDI-TOF MS analysis, and G+C contents clearly differentiated the isolates from their known relatives. Besides, the woodpecker isolates significantly differed from each other in their whole-cell protein profiles, DNA fingerprints, and ANIb values. In conclusion, the isolated microorganisms constitute members of two new species, for which the names Kocuria uropygioeca sp. nov. and Kocuria uropygialis sp. nov. are proposed. The type strains are 36T (DSM 101740T=LMG 29265T) and 257T (=DSM 101741T=LMG 29266T) for K. uropygialis sp. nov. and K. uropygioeca sp. nov., respectively. PMID- 29169692 TI - Anthropometric growth study of the ear in a Chinese population. AB - BACKGROUND: A large number of anthropometric studies of the auricle have been reported in different nations, but little data were available in the Chinese population. The aim of this study was to analyze growth changes in the ear by measuring the width and length of ears in a Chinese population. METHODS: A total of 480 participants were enrolled and classified into 1-, 3-, 5-, 7-, 9-, 12-, 14 , and 18-year groups (half were boys and half were girls in each group). Ear length, ear width, body weight, and body length were measured and recorded; ear index was calculated according to ear length and ear width. The growth of auricle and differences between genders were analyzed. Growth of ear in relation to body height and weight and the degree of emphasis on the length and width of the auricle were also analyzed. RESULTS: Ear length and width increased with age. Ear length achieved its mature size in both 14-year-old males and females. Ear width reached its mature size in males at 7 years and in females at 5 years. Different trends of ear index were shown between males and females. People in this population paid more attention to the length than the width of the auricle. CONCLUSIONS: The data indicated that ear development followed increase in age. There were gender and ethnic difference in the development of ear. These results may have potential implications for the diagnosis of congenital malformations, syndromes, and planning of ear reconstruction surgery. PMID- 29169693 TI - Specific localization of manserin peptide in the rat carotid body. AB - The carotid body, located at the bifurcation of the common carotid artery, is a small sensory organ that detects changes in oxygen concentration and plays a vital role in controlling respiration. Although several molecules, such as neurotransmitters and neuropeptides, are involved in the regulation of the respiratory system, their detailed mechanisms have not been established yet. This study identifies that the presence of manserin, a neuropeptide, in the carotid body may play a crucial role in regulating respiration. The carotid bodies of adult Wistar rats were perfused with paraformaldehyde, and the frozen sections were subjected to immunohistochemical analyses. The carotid body comprises two distinct types of cells, neuron-like glomus cells and glial-like sustentacular cells. We used specific antibodies to distinguish the specific location of manserin in the carotid body, which included a tyrosine hydroxylase-positive antibody for glomus cells and an S100 protein antibody for sustentacular cells. Immunofluorescence analysis revealed that while tiny, round signals were exclusively observed in the cytoplasm of glomus cells, no signals were observed in sustentacular cells. Because manserin is believed to be secreted from precursor proteins by the endoproteolytic processing of a large precursor protein called secretogranin II, manserin secretion systems may exist in the carotid body, and thus, behave as potential regulators of respiration in the carotid body. PMID- 29169694 TI - Vitamin E can improve behavioral tests impairment, cell loss, and dendrite changes in rats' medial prefrontal cortex induced by acceptable daily dose of aspartame. AB - Aspartame is an artificial sweetener used in about 6000 sugar-free products. Aspartame consumption could be associated with various neurological disorders. This study aimed to evaluate the effect of aspartame onmedial Prefrontal Cortex (mPFC) as well as neuroprotective effects of vitamin E. The rats were divided into seven groups, including distilled water, corn oil, vitamin E (100mg/kg/day), and low (acceptable daily dose) and high doses of aspartame (40 and 200mg/kg/day) respectively, with or without vitamin E consumption, for 8 weeks. Behavioral tests were recorded and the brain was prepared for stereological assessments. Novel objects test and eight-arm radial maze showed impairmentoflong- and short termmemoriesin aspartame groups. Besides, mPFC volume, infralimbic volume, neurons number, glial cells number, dendrites length per neuron,and number of spines per dendrite length were decreased by 7-61% in the rats treated with aspartame. However, neurons' number, glial cells number, and rats' performance in eight-arm radial mazes were improved by concomitant consumption of vitamin E and aspartame. Yet, the mPFC volume and infralimbic cortex were protected only in the rats receiving the low dose of aspartame+vitamin E. On the other hand, dendrites length, spines number,and novel object recognition were not protected by treatment with vitamin E+aspartame. The acceptable daily dose or higher doses of aspartame could induce memory impairments and cortical cells loss in mPFC. However, vitamin E could ameliorate some of these changes. PMID- 29169695 TI - Immunohistochemical analysis of the distribution of molecules involved in ionic and pH regulation in the lancelet Branchiostoma floridae (Hubbs, 1922). AB - The aim of present work is to analyse the distribution of carbonic anhydrase II (CAII), cystic fibrosis transmembrane regulator (CFTR), vacuolar-type H+-ATPase (V-H+-ATPase), Na+/K+ ATPase, Na+/H+ exchanger (NHE) and SLC26A6 (solute carrier family 26, member 6), also known as pendrin protein, in the lancelet Branchiostoma floridae in order to go in depth in the evolution of osmoregulation and pH regulation in Chordates. In view of their phylogenetic position, lancelets may indeed provide a critical point of reference for studies on osmoregulation evolution in Chordates. The results of present work demonstrated that, except to Na+/K+ ATPase that is strongly expressed in nephridia only, all the other studied molecules are abundantly present in skin, coelomic epithelium, renal papillae and nephridia and hepatic coecum. Thus, it is possible to hypothesize that also in lancelet, as in fish, these organs are involved in pH control and ionic regulation. In the digestive tract of B. floridae, the intestine epithelium was weakly immune-reactive to all tested antibodies, while the hepatic coecum showed an intense immunoreactivity to all molecules. Since in amphioxus the hepatic coecum functions simultaneously as stomach, liver and pancreas, these immunohistochemical results proved the secretion of H+ and HCO3- ions, typical of digestive process. Colocalization studies indicated a co-expression of the studied proteins in all considered organs, excluding NHE and pendrin for renal papillae, since some renal papillae are NHE immunopositive only. PMID- 29169696 TI - Efficacy and feasibility of opioids for burn analgesia: An evidence-based qualitative review of randomized controlled trials. AB - Opioids are commonly used for burn analgesia, but no comprehensive reviews have been published on such use. We aimed to assess the literature regarding the effectiveness and side effects of opioids both in adult and pediatric burn patients. We conducted a systematic search of the PubMed, Embase, Cochrane, and Web of Science databases. Information on study characteristics, results, and interventions was extracted. The review identified nine studies that satisfied the inclusion criteria. Burn sizes of patients ranged from 1% to 62% of the body. The examined studies showed that dressing or cream containing morphine could potentially decrease pain, use of analgesics, and side effects associated with systemic opioid medications compared with control groups. Oral transmucosal fentanyl citrate (OTFC) was equivalent, or even preferable, to oral morphine, hydromorphone, and oxycodone in provision of analgesia for burn wound care in pediatric patients. Intranasal fentanyl (INF) was equivalent to oral morphine in burn wound care both in adult and pediatric patients. OTFC and INF could be considered as viable non-invasive analgesic alternatives to oral opioids for procedural burn pain. However, the level of evidence still seems quite uncertain because of the limited sample size.

AB - BACKGROUND: Randomized controlled clinical trials (CTs) are gold standard tools for assessing interventions. Although burn CTs have improved care, their status, publication frequency, and publication quality are not known. OBJECTIVES: (1) Characterize burn CTs by analyzing location, completion status, temporal trend, and funding sources. (2) Assess quality of trial reporting. DATA SOURCES: CT records were obtained from ClinicalTrials.gov and WHO's CT Registry (searched May 2017). Publications were obtained from PubMed, Google Scholar, OVID MEDLINE, and ClinicalTrials.gov (searched June 2017). PUBLICATION APPRAISAL: 23-item rubric adapted from CONSORT and ICH E3 guidelines. RESULTS: 738 burn CTs were identified globally, of which majority were publically-funded (77%), ongoing (52%), and assessed behavioral, pharmacological, device-based, dietary-based, and biological/procedural interventions. Amongst the ended trials, 69 (28%) published their findings. Significantly fewer industry-funded trials published findings (14% vs 33% publically-funded). Quality of reporting was suboptimal, and most underreported categories were trial phase, severity, and sample size estimation. LIMITATIONS: Incomplete, outdated, and non-registered CTs which are difficult to track. CONCLUSIONS: Burn trials are proliferating in number, location, and interventions assessed. Only a small proportion are published and quality of reporting is suboptimal. IMPLICATIONS OF KEY FINDINGS: Burn researchers should aim to register and report on all clinical trials regardless of outcome. Superior a priori design can reduce precocious termination and mandatory reporting of data fields can improve quality of reporting. Systematic review registration number: CRD42017068549. PMID- 29169701 TI - Aromatherapy for the relief of symptoms in burn patients: A systematic review of randomized controlled trials. AB - BACKGROUND: Aromatherapy is often used to manage several conditions, including pain, psychological distress, and burn-related symptoms. The objective of this review was to assess the current evidence regarding the efficacy of aromatherapy as a treatment for burn wounds. METHODS: The following fifteen databases and trial registries were searched for studies published between their dates of inception and January 2017: AMED, CINAHL, EMBASE, MEDLINE, and the Cochrane Central Register of Controlled Trials (CENTRAL), as well as six Korean medical databases and four Iranian databases. All the trials included in the review were randomized controlled trials (RCTs) assessing the efficacy any type of aromatherapy as a treatment for burn-related symptoms. Study selection and data extraction were performed by two independent reviewers, and the risk of bias (ROB) in the trials included in the review was assessed using the Cochrane ROB assessment tool. RESULTS: Four RCTs met our inclusion criteria, including two RCTs comparing the efficacy of aroma inhalation as a treatment for pain and anxiety with that of placebo controls. Both studies showed that aroma inhalation was superior to placebo with respect to relieving pain and anxiety. The third study compared the effects of aroma inhalation on sleep quality with those of music therapy and showed that two the treatments exert equivalent effects on the above parameter, and the fourth trial compared the ability of aroma inhalation to reduce pain and anxiety with that of no treatment. The results showed that aroma inhalation can reduce pain but not anxiety. CONCLUSIONS: The evidence from the above trials is not sufficient to conclude that aromatherapy effectively relieves symptoms in patients with burns. However, the findings of the trials do not seem very plausible, and the trials themselves were of low quality and included only small numbers of patients. Studies that are adequately powered and feature better designs are needed to investigate the potential mechanisms underlying the effects of aroma therapy on pain and anxiety. PMID- 29169702 TI - Relationship between multidisciplinary critical care and burn patients survival: A propensity-matched national cohort analysis. AB - OBJECTIVE: The aims of this study are: firstly, to investigate if admission to specialized burn critical care units leads to better clinical outcomes; secondly, to elucidate if the multidisciplinary critical care contributes to this superior outcome. METHODS: A multi-centre cohort analysis of a prospectively collected national database of 1759 adult burn patients admitted to 13 critical care units in England and Wales between 2005 and 2011. Units were contacted via telephone to establish frequency and constitution of daily ward rounds. Critical care units were categorized into 3 settings: specialized burns critical care units, generalized critical care units and 'visiting' critical care units. Multivariate logistic regression analysis and propensity dose-response analysis were used to calculate risk adjusted mortality. RESULTS: Multivariate logistic regression analysis shows that admission to a specialized burn critical care service is independently associated with significant survival benefit compared to generalized critical care unit (adjusted OR for in-hospital death 1.81, [95% CI, 1.24, 2.66]) and 'visiting' critical care services (adjusted OR for in-hospital death 2.24 [95% CI, 1.49, 3.38]). Further analysis using propensity dose-response analysis demonstrates that risk-adjusted in-hospital mortality rate decreased as the dose of multidisciplinary care increased, with an adjusted odds ratio of 1 (specialized burn critical care units), 1.81 (generalized critical care units) and 2.24 ('visiting' critical care units). CONCLUSIONS: Admission to a specialized burn critical care service is independently associated with significant survival benefit. This is, at least in part, due to care being provided by a fully integrated multidisciplinary team. PMID- 29169703 TI - Laparoscopic partial nephrectomy: Comparative study of the transperitoneal pathway and the retroperitoneal pathway. AB - INTRODUCTION: Laparoscopic partial nephrectomy is the recommended treatment for tumours smaller than 4cm in cases where it is feasible. Depending on the location of the tumour, the transabdominal or direct retroperitoneal pathway may be considered. OBJECTIVE: To compare the transperitoneal (TPPN) and direct retroperitoneal (RPPN) partial nephrectomies performed between 2007 and 2016. MATERIAL AND METHODS: A retrospective study was conducted on 71 patients who underwent TPPN (42) or direct RPPN (29) partial nephrectomy. We evaluated the characteristics of the patients and tumours, including tumour complexity (PADUA, RENAL, C-index). We compared perioperational variables, including the complications between the 2 pathways. RESULTS: We found no differences in terms of age, sex, Charlson's score and BMI. A larger proportion of patients in the direct RPPN group had prior major abdominal surgery (7.1 vs. 24.1%; P=.043). There were no differences in tumour size, laterality, polarity or complexity in any of the assessed scores. There were significant differences in tumour location (anterior/middle/posterior) between the TPPN and RPPN groups (54.8/31/14.3 vs. 3.4/13.8/82.8%; P<.001). There were no differences in the surgical time or length of stay. The TPPN group had a smaller urinary tract opening (4.8 vs. 27.6%; P=.007) and a higher percentage of haemostatic renorrhaphy (47.6 vs. 17.2%; P=.008). There were no differences in the need for warm ischaemia, in the changes in haemoglobin levels or in the glomerular filtration rate. The complication rates were similar for the two series. CONCLUSION: The two pathways show similar results in terms of renal function preservation, complications and oncological results. However, we recommend understanding both techniques and adapting the access type to the clinical case.

AB - PURPOSE: To determine the cumulative incidence of overall and severe radiation cystitis in a high volume cohort of patients and to investigate its potential predictive factors. METHODS: We have performed a retrospective analysis of clinical data from patients diagnosed with localized prostate cancer and treated with radiotherapy at our institution (June 2005-January 2013), and quantified the cumulative incidence of radiation cystitis. Cox regression analysis and Kaplan Meier curves were computed to evaluate the determinants of radiation cystitis. RESULTS: Data from 783 patients was retrieved (557 treated with primary radiotherapy, 188 with adjuvant and 38 with salvage). Median follow-up time was 49 months (P25-P75: 31.8-69.3). At 5 years of follow-up, cumulative incidence of overall and severe radiation cystitis was 9.1 and 1.6%, respectively. No association was found between the incidence of radiation cystitis and age, tumor T stage, baseline PSA level, Gleason score, D'Amico risk classification, radiotherapy setting (primary versus adjuvant versus salvage) or radiation dose applied. CONCLUSIONS: Within our cohort, radiation cystitis is an uncommon complication of prostatic radiotherapy treatment, and severe cases requiring hospitalization are even more infrequent. We found no association between tumor characteristics, radiotherapy setting or radiation dose and the cumulative incidence of radiation cystitis.

AB - INTRODUCTION AND OBJECTIVE: This systematic review of the literature has been focused on determining the clinical usefulness of random bladder biopsies (RB) in the diagnosis of carcinoma in situ. A meta-analysis was performed to establish the clinic and pathological factors associated to positive biopsies. EVIDENCE ACQUISITION: A systematic review was performed using Pubmed/Medline database according to the PRISMA guidelines. Thirty-seven articles were included, recruiting a total of 12,657 patients, 10,975 were submitted to RB. EVIDENCE SYNTHESIS: The overall incidence of positive RB was 21.91%. Significant differences were found in the incidence of positive RB when patients were stratified according to urine cytology result, tumor multiplicity, tumor appearance, stage and grade. The results of the meta-analysis revealed that the presence of positive cytology, tumor multiplicity, non-papillary appearance tumors, stage T1 and histological grades G2 and G3 represent the risk factors to predict abnormalities in RB. CONCLUSIONS: The incidence of positive RB in patients with non-muscle invasive bladder cancer was 21.91%. The maximum usefulness of RB was observed when these are performed in a standardized way. The results of the meta-analysis showed that besides positive cytology and non papillary appearance tumors, tumor multiplicity and histological grades G2 and G3 represent risk factors associated to positive RB, suggesting that the use of RB might be extensive to the intermediate risk group of the European Organization for Research and Treatment of Cancer (EORTC).

AB - Endometriosis is a frequent pathology with a high incidence of deep infiltrating endometriosis and complex forms that can affect 20% of patients with endometriosis. The incidence of infertility associated with endometriosis can reach 50%. The complexity of care requires the creation of expert centers working in networks with general practitioners. Criteria for defining these expert centers are being drawn up, based on structural criteria (multidisciplinary consultation meeting), links with medical assistance structures for procreation and activity criteria for severe and complex forms (number of interventions per center and per surgeon). PMID- 29169710 TI - Dysmetabolic iron overload syndrome (DIOS). AB - Dysmetabolic iron overload syndrome (DIOS) corresponds to mild increase in both liver and body iron stores associated with various components of metabolic syndrome in the absence of any identifiable cause of iron excess. It is characterized by hyperferritinemia with normal or moderately increased transferrin saturation, one or several metabolic abnormalities (increased body mass index with android distribution of fat, elevated blood pressure, dyslipidaemia, abnormal glucose metabolism, steatohepatitis), and mild hepatic iron excess at magnetic resonance imaging or liver biopsy. Alteration of iron metabolism in DIOS likely results from a multifactorial and dynamic process triggered by an excessively rich diet, facilitated by environmental and genetic cofactors and implying a cross-talk between the liver and visceral adipose tissue. Phlebotomy therapy cannot be currently considered as a valuable option in DIOS patients. Sustained modification of diet and life-style habits remains the first therapeutic intervention in these patients together with drug control of increased blood pressure, abnormal blood glucose and dyslipidaemia when necessary.

AB - The incidence of twin pregnancies has increased steadily for the last 40 years due to assisted reproductive technology and increased maternal childbearing age. Multiple pregnancies, especially monochorionic twin pregnancies, carry a high risk for the mother and the fetuses and require close follow-up. Twins are exposed to a higher risk of perinatal anoxia, in utero fetal demise, preterm birth, congenital malformations, fetal growth restriction, and vascular complications. Compared to singletons, twins are at higher risk of perinatal mortality and impaired neurodevelopmental outcome, justifying a thorough follow up by pediatricians, including assessment and management of familial and psychosocial impact. This paper discusses the epidemiological, obstetrical, and genetic issues raised by twin pregnancies and reviews the data on the perinatal and neurological long-term outcomes of twins, as well as the psychosocial impact of multiple births on twins and their families. PMID- 29169713 TI - [Detection and codification of adverse drug reactions in a mother-child university hospital]. AB - INTRODUCTION: In view of the underdeclaration of adverse drug reactions (ADRs), there is a need for optimizing their reporting. To improve our declaration, a pharmacovigilance program was started in 2006 at our center and measures were progressively started (weekly patient rounds, monthly report, etc.). The objectives of the study were to describe and compare the annual average incidence of the ADRs coded by the medical archivists from 1 April 1989 to 31 March 2010 (period 1) and from 1 April 2010 to 31 March 2015 (period 2), to determine the therapeutic classes of drugs associated with ADRs according to age and determine the percentage of ADRs that are declared to Health Canada. METHODS: This was a nonexperimental, descriptive, and retrospective study in a mother-child university hospital. All the ADRs that arose with patients less than 18 years old during period 2 were included. The results of a previous study, conducted during period 1 were used. A Student t-test was used to compare the mean annual incidence and the average number of ADRs per year between the two periods. RESULTS: The average number of ADRs per year was 225.7+/-65.1 ADRs during period 1 versus 429.6+/-52.1 ADRs during period 2 (P<0.01). The mean annual incidence of the ADRs was 1.64%+/-0.41% during period 1 versus 3.17%+/-0.43% during period 2 (P<0.01). Throughout the study period, the mean annual gravity and mortality index were stable. The ADRs caused by antibiotics/antifungals, anticancer agents, opiates, and corticoids accounted for more than 50% of the total ADRs from 1989 1990 to 2014-2015. Only 37% of the ADRs were declared to Health Canada during period 1 versus 41% during period 2. CONCLUSION: This study highlighted a progressive increase in the codification of the ADRs in the pediatric population from 1989-1990 to 2014-2015. No causal effect could be obtained between the measures that we implemented in 2006 and the improvement seen with the ADR codification, but we can reasonably suspect a positive impact. PMID- 29169714 TI - [Idiopathic nephrotic syndrome]. AB - Nephrotic syndrome (NS) is defined by massive proteinuria and hypoalbuminemia, with resulting hyperlipidemia and edema. The most common cause of NS in children is idiopathic nephrotic syndrome (INS), also called nephrosis. Its annual incidence has been estimated to 1-4 per 100,000 children and varies with age, race, and geography. Many agents or conditions have been reported to be associated with INS such as infectious diseases, drugs, allergy, vaccinations, and malignancies. The disease may occur during the 1st year of life, but it usually starts between the ages of 2 and 7 years. INS is characterized by a sudden onset, edema being the major presenting symptom, but may rarely be discovered during a routine urine analysis. The disease may also be revealed by a complication such as hypovolemia, infection (pneumonia and peritonitis due to Streptococcus pneumoniae), deep-vein or arterial thromboses, and pulmonary embolism. Renal biopsy is usually not indicated in a child aged 1-10 years with typical symptoms and a complete remission with corticosteroids. Conversely, it is indicated in children under 1 year in case of macroscopic hematuria, hypertension, low C3 levels, persistent renal failure, or steroid resistance. Steroid therapy is applied in all children whatever the histopathology. Initial prednisone therapy in France consists of 60mg/m2 administered daily for 4 weeks (maximum dose, 60mg/day), followed by alternate-day prednisone with tapering doses. Eight-five to 90 % patients are steroid-responsive and may relapse, but the majority still responds to steroids over the subsequent courses. Only 1-3 % of patients who are initially steroid-sensitive subsequently become steroid resistant. Children with primary or secondary steroid-resistance are at risk of end-stage kidney disease. Symptomatic treatment includes salt restriction, fluid restriction when natremia is less than 125 meq/L, reduction of saturated fat and carbohydrates, calcium and vitamin D supplements, anticoagulation, and vaccination. Albumin infusions are only indicated in case of complications. Diuretics should be restricted to cases of severe edema, after hypovolemia has been corrected.

AB - Decisions regarding whether to initiate or forgo intensive care for extremely premature infants are often based on gestational age alone. However, other factors also affect the prognosis for these patients and must be taken into account. After a short review of these factors, we present the thoughts and proposals of the Risks and Pregnancy department. The proposals are to limit emergency decisions, to better take into account other factors than gestational age and prenatal predicted fetal weight in assessing the prognosis, to introduce multidisciplinary consultation in the evaluation and proposals that will be discussed with the parents, and to separate prenatal steroid therapy from decision-making regarding whether or not to administer intensive care.

PMID- 29169716 TI - [Body mass index charts of Algerian children and adolescents (6-18 years)]. AB - The body mass index (BMI) is widely accepted as a measure of overweight and obesity in children. There are no BMI reference charts for Algerian children and adolescents. The purpose of this study was to construct BMI percentile curves appropriate for children aged 6-18 years in Algeria. The weight and height of 7772 (54.9% girls) healthy schoolchildren from Constantine (eastern Algeria) were measured in 2008/2009. Weight and height for age curves based on the same sample were published previously. The BMI for age percentile curves were estimated in girls and boys separately using the LMS smoothing method. In both sexes, the median BMI increased with age. Girls had lower BMI values than boys before the age of 10 years but they were higher after this age until 18 years of age. Within the study population, the prevalence of overweight (including obesity) and obesity in girls and boys together was 13.7% and 3.0%, respectively, according to the International Obesity Task Force (IOTF) and 16.9% and 4.9% according to the World Health Organization (WHO) (2007). The median BMI curves of Algerian girls and boys were generally lower than those observed in other Arab countries. Compared with other references, the median BMI values of girls were lower than those of a Belgian Flemish population and WHO 2007 until 14 years of age and higher than the French reference between 7 and 18 years of age. The BMI values of Algerian boys were close to the Belgian (Flemish population), French and WHO 2007 references between 6 and 9 years of age and generally lower thereafter. These BMI curves are complementary to the height and weight charts published previously for the assessment of growth in children and adolescents. They were developed according to international guidelines and could serve as a national reference. They could be used as a complement to the 0- to 5-year-old WHO 2006 standards.

For non-breastfed infants, the main dietetic move is the replacement of the standard infant formula with a formula for which the protein fraction has been modified. This formula can be based on hydrolyzed cow's milk proteins, rice proteins or amino acids. Monitoring the growth of these children is essential. The reintroduction of cow's milk, raw or heated, should always be made carefully and gradually. As the child grows and remains allergic, the use of heated (baked) milk substantially eases his/her feeding. PMID- 29169719 TI - Fracture Gap Reduction With Variable-Pitch Headless Screws. AB - PURPOSE: Fully threaded, variable-pitch, headless screws are used in many settings in surgery and have been extensively studied in this context, especially in regard to scaphoid fractures. However, it is not well understood how screw parameters such as diameter, length, and pitch variation, as well as technique parameters such as depth of drilling, affect gap closure. METHODS: Acutrak 2 fully threaded variable-pitch headless screws of various diameters (Standard, Mini, and Micro) and lengths (16-28 mm) were inserted into polyurethane blocks of "normal" and "osteoporotic" bone model densities using a custom jig. Three drilling techniques (drill only through first block, 4 mm into second block, or completely through both blocks) were used. During screw insertion, fluoroscopic images were taken and later analyzed to measure gap reduction. The effect of backing the screw out after compression was evaluated. RESULTS: Drilling at least 4 mm past the fracture site reduces distal fragment push-off compared with drilling only through the proximal fragment. There were no significant differences in gap closure in the normal versus the osteoporotic model. The Micro screw had a smaller gap closure than both the Standard and the Mini screws. After block contact and compression with 2 subsequent full forward turns, backing the screw out by only 1 full turn resulted in gapping between the blocks. CONCLUSIONS: Intuitively, fully threaded headless variable-pitch screws can obtain compression between bone fragments only if the initial gap is less than the gap closed. Gap closure may be affected by drilling technique, screw size, and screw length. Fragment compression may be immediately lost if the screw is reversed. CLINICAL RELEVANCE: We describe characteristics of variable-pitch headless screws that may assist the surgeon in screw choice and method of use. PMID- 29169720 TI - Treatment of Radial Head Fractures and Need for Revision Procedures at 1 and 2 Years. AB - PURPOSE: Optimal treatment strategies for radial head fractures remain a subject of debate. We examined national practice patterns in the management of radial head fractures to determine rates of surgical treatment, type of surgery employed, and the incidence of reoperation. METHODS: Between 2007 and 2011, we identified patients with radial head fractures along with their associated injuries by International Classification of Diseases, Ninth Revision codes in a national database of orthopedic insurance records. For those who underwent surgery, the type of intervention was identified and each patient was observed to determine whether a subsequent procedure was needed by 1 and 2 years. Chi-square analysis was performed to make comparisons between groups. RESULTS: A total of 58,404 radial head fractures were identified between 2007 and 2011; of these, 2,981 underwent surgical treatment (5.1%). Rates of surgical intervention were significantly higher in the context of associated injuries. Among the 2,981 radial head fractures treated surgically, 57.1% underwent open reduction internal fixation (ORIF), 37.9% were treated with radial head arthroplasty, and 4.9% underwent radial head excision. When the surgically treated radial head fracture was associated with a coronoid fracture, elbow dislocation, or proximal ulna fracture, 64.2%, 54.3%, and 47.2% were treated with arthroplasty, respectively, compared with 32.6%, 41.9%, and 52.6% treated with ORIF, respectively. After initial surgical treatment, 12.7% and 14.4% of radial head fractures that underwent ORIF required a secondary surgery at 1 and 2 years, respectively, compared with 8.6% and 10.7% of radial head arthroplasties and 8.3% and 8.4% of resections. CONCLUSIONS: Rates of arthroplasty were significantly higher in the context of associated injury, particularly in the setting of a coronoid fracture or elbow dislocation. Fractures initially treated with ORIF had a higher rate of revision surgery at both 1 and 2 years after the index procedure compared with arthroplasty. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II. PMID- 29169721 TI - Active Range of Motion Over Time in Patients With Obstetrical Brachial Plexus Palsy: A 10-Year Analysis. AB - PURPOSE: In our experience, and from the personal report of others, children with obstetrical brachial plexus palsy appear to lose some of their initially recovered active range of motion over the time in both operated and nonsurgical patients. This study investigates whether such a diminution of active movement occurs over time. METHODS: We performed a retrospective analysis of data from our obstetrical brachial plexus clinic. Between 1991 and 2000, 139 patients with a minimum follow-up of 10 years were included in the study. Patients were divided into a nonsurgical group (n = 42) and a group who underwent either primary or secondary brachial plexus reconstruction or both (n = 97). Fifteen joint movements were assessed at 2, 4 to 6, and 9 to 11 years of age and at later final follow-up using the Active Movement Scale. Repeated measures analysis using age at each visit as the repeated measures covariate was undertaken. RESULTS: Active movement scores were not diminished when patients were evaluated at the 10-year follow-up visit. CONCLUSIONS: The suggested loss of active range of motion over time is not demonstrated at 10-year follow-up. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic III.

We review current methods for examining, diagnosing, and treating pisotriquetral instability. PMID- 29169723 TI - Protective effects of allicin on 1,3-DCP-induced lipid metabolism disorder in HepG2 cells. AB - Allicin (2-propene-1-sulfinothioic acid S-2-propenyl ester), with quite a good range of hepatoprotective and antineoplastic properties, is a functional substance from garlic (Allium sativum L.) The purpose of this study was to provide evidence that allicin could protect 1,3-DCP-induced lipid metabolism disorder in HepG2 cells. Allicin reduced the accumulation of triglycerides (TG) and total cholesterol (TC) in 1,3-DCP-induced HepG2 cells. Allicin significantly increased the phosphorylation of AMP-activated protein kinase (AMPK) and down regulated the levels of sterol regulatory element binding protein-1 (SREBP-1) and sterol regulatory element binding protein-2 (SREBP-2) in 1,3-DCP-induced HepG2 cells. Additionally, allicin had obvious recovery influence on the phosphorylation level of PKA and CREB in 1,3-DCP-induced HepG2 cells. These observations indicated that allicin alleviated lipid metabolism disorder induced by 1,3-DCP in HepG2 cells by regulating AMPK-SREBPs and PKA-CREB signaling pathways. PMID- 29169724 TI - BMSCs protect against liver injury via suppressing hepatocyte apoptosis and activating TGF-beta1/Bax singling pathway. AB - Many factors cause liver injury, including chronic consumption of alcohol, irregular use of drugs, excessive levels of arsenic in water. This study aims to investigate role of bone marrow-derived mesenchymal stem cells (BMSCs) in liver injury recovery and to explore mechanism. BMSCs and primary hepatocytes were isolated, cultured and identified. Hepatocyte model and hepatic fibrosis (HF) model were established using carbon tetrachloride (CCL-4). The role of BMSCs were investigated in both in vitro and in vivo levels. Cell proliferation was examined using MTT assay. Transforming growth factor-beta1 (TGF-beta1), Bcl-2 and Bax expression were detected using western blot and real-time PCR, respectively. Results indicated that BMSCs and primary hepatocytes were successfully isolated and identified, and hepatocyte model was successfully established. BMSCs and HGF treatment enhance viability of normal hepatocytes and hepatocyte injury model. Cell viability in BMSCs treatment and Bax-1 inhibitor treatment group was higher significantly compared to normal hepatocyte control and injury hepatocyte model, respectively (P<0.05). Bax-1 expression was significantly lower and Bcl-2 was significantly higher in Bax-1 inhibitor treatment and BMSCs treatment group compared to normal hepatocyte control (normal rats) and injury hepatocyte model (HF model), respectively (P<0.05). BMSCs significantly decreased ALT and AST levels compared to Saline group (P<0.05). In conclusion, function of BMSCs in liver injury was triggered by inhibiting hepatocyte apoptosis and leading cell proliferation through TGF-beta1/Bax singling pathway. Our study proved protective role of BMSCs against liver injury via TGF-beta1/Bax pathway, which would enrich application of BMSC in clinical. PMID- 29169725 TI - Ginsenoside Rg3 inhibits colorectal tumor growth via down-regulation of C/EBPbeta/NF-kappaB signaling. AB - Colorectal cancer (CRC), the third most frequent occurred cancer, is associated with high mortality and extremely poor prognosis. Ginsenoside Rg3 (Rg3), one of the pharmacologically active components of traditional Chinese herbal medicine Panax ginseng, exerts antitumor effects against several types of cancer growth, including colorectal cancer. However, the detailed molecular mechanisms and particularly the signaling pathways that are decisive in this process are not yet fully elucidated. The present study was carried out to determine the antitumor effects of Rg3 using human colorectal cells in vitro and Xenograft tumor model of human colon cancer in vivo. We found that Rg3 effectively suppressed the proliferation of cancer cells in three human colorectal cancer cell lines (HCT116, HT29, SW480). In addition, intraperitoneal injection of Rg3 for 3 weeks significantly inhibited the growth of xenografts in nude mice. Furthermore, we determined the potential underlying mechanisms for these actions. Treatment with Rg3 significantly inhibited the transactivation of C/EBPbeta and NF-kappaB, as well as the association of C/EBPbeta with p65-NFkappaB in nucleus. However, when SW-480 cells were co-transfected with C/EBPbeta, or pretreatment with TNFalpha, Rg3 failed to inhibit tumor growth. Taken together, our results revealed a robust anti-tumor effect of Rg3, which is mediated by inhibition of C/EBPbeta/NF-kappaB signaling. PMID- 29169726 TI - Piperine (PP) enhanced mitomycin-C (MMC) therapy of human cervical cancer through suppressing Bcl-2 signaling pathway via inactivating STAT3/NF-kappaB. AB - Piperine (PP), an alkaloid from black and long peppers (Piper nigrum Linn &Piper longum Linn), exhibits antitumor activities in vitro and in vivo. We investigated the ability of piperine (PP) to reverse the drug resistance of human cervical cancer cells. In our study, the cervica cancer cells resistant to mitomycin-C (MMC) treatment were used. We found the growth inhibitory effects of piperine on human cervical cancer cell, which were resistant to MMC. Piperine and MMC co treatment resulted in a dose-dependent suppression of the cell proliferation. Decreasing of phosphorylated-signal transducer and activator of transcription (p STAT3) was linked to the suppression of p65 by PP and MMC combinational treatment. Additionally, the presence of PP potentiated the effects of MMC on apoptosis induction in cervical cancer cells with drug resistance, which was dependent on Bcl-2 inhibition. The pro-apoptotic proteins of Bax and Bid were up regulated, accompanied with Caspase cleavage. Moreover, in mice xenograft models, the combined therapy inhibited tumor growth compared to the PP or MMC mono therapy group. Our data indicated a novel therapeutic strategy of PP to potentiate MMC-induced anti-tumor effect on cervical cancer cells with drug resistance through blocking p-STAT3/p65 and Bcl-2 activation. PMID- 29169727 TI - Effects of separate and concurrent supplementation of Nano-sized clinoptilolite and Nigella sativa on oxidative stress, anti-oxidative parameters and body weight in rats with type 2 diabetes. AB - OBJECTIVES: The objective of this study was to investigate the effects of separate and concurrent supplementation of natural nano-sized clinoptilolite (NCLN) and Nigella sativa (NS) on oxidative stress (OS), anti-oxidative parameters and body weight (BW) in high-fat-diet (HFD)/streptozotocin (STZ) induced diabetic rats. METHODS: In this experimental study, 42 male Wistar rats were divided into diabetic (n=36) and non-diabetic (n=6) groups. The diabetic group (DG) was fed with a HFD for one month, then injected with intra-peritoneal single dose STZ (35 mg/kg BW). The DG was divided into 4 subgroups: [1] control (DC), [2] NS 1%/food, [3] NCLN 2%/food, [4] NS 1%/food + NCLN 2%/food. At the end of the 7th week, malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPX) levels and total antioxidant capacity (TAC) were measured. RESULTS: The MDA level was decreased in the NCLN (p = 0.011) and NCLN+NS (p = 0.007) groups compared to the DC group. The GPX level increased in the NS and NCLN groups compared to the DC group (p = 0.014 and p = 0.034). In addition, the level of TAC demonstrated increase in the untreated DG and NS groups, as compared to the normal control (NC) group (pDC = 0.031 and pNS = 0.024). Moreover, in the NS+NCLN group, the level of SOD decreased in comparison to the NS and NCLN groups (p < 0.01). At the end of the 7th week, BW decreased in the diabetic subgroups in comparison to the NC group. Treatment with NS and/or NS+NCLN insignificantly prevented severe weight loss in the fifth week of the treatment. CONCLUSIONS: According to results, separate supplementation of NS and NCLN was more beneficent on anti-oxidative parameters than concurrent supplementation of NS and NCLN. PMID- 29169728 TI - Morphological analysis of mitochondria for evaluating the toxicity of alpha synuclein in transgenic mice and isolated preparations by atomic force microscopy. AB - A key molecular event in the pathogenesis of Parkinson's disease is mitochondrial damage caused by alpha-synuclein (alpha-syn). Mitochondria mediates both necrosis and apoptosis, which are associated with morphological changes. However, the mechanism by which alpha-syn alters mitochondrial morphology remains unclear. To address this issue, we investigated mitochondrial permeability transition pore (mPTP) opening and changes in cardiolipin (CL) levels in mitochondria isolated from the brain of Thy1alpha-syn mice. Cytoplasmic cytochrome C and cleaved caspase-3 protein levels were upregulated in the brain of transgenic mice. Morphological analysis by atomic force microscopy (AFM) suggested a correlation between mitochondrial morphology and function in these animals. Incubation of isolated mitochondria with recombinant human alpha-synuclein N terminus (alpha syn/N) decreased mitochondrial CL content. An AFM analysis showed that alpha syn/N induced mitochondrial swelling and the formation of pore-like structures, which was associated with decreased mitochondrial transmembrane potential and complex I activity. The observed mitochondrial dysfunction was abrogated by treatment with the mPTP inhibitor cyclosporin A, although there was no recovery of CL content. These results provide insight into the mechanism by which alpha syn/N directly undermines mitochondrial structure and function via modulation of mPTP opening and CL levels, and suggests that morphological analysis of isolated mitochondria by AFM is a useful approach for evaluating mitochondrial injury. PMID- 29169729 TI - miR-193b-3p possesses anti-tumor activity in ovarian carcinoma cells by targeting p21-activated kinase 3. AB - miR-193b-3p was found to be downregulated and contributed to ovarian cancer (OC) progression. In the present study, we aimed to study the detailed role of miR 193b-3p in the development of OC and the underlying molecular mechanism. The results showed that miR-193b-3p was downregulated while PAK3 was upregulated in OC cells. Ectopic expression of miR-193b-3p and PAK3 knockdown repressed cell proliferation, promoted paclitaxel-induced cytotoxicity, and reinforced paclitaxel-mediated caspase-3 activity increase in OC cells. Notably, miR-193b-3p was identified to directly target PAK3 and suppressed PAK3 expression. Moreover, enforced expression of PAK3 partially overturned the effects of miR-193b-3p on OC cell proliferation and paclitaxel sensitivity. In conclusion, miR-193b-3p possessed anti-tumor activity in OC through inhibiting cell proliferation and enhancing paclitaxel sensitivity by targeting PAK3. Therefore, our study suggested that the miR-193b-3p/PAK3 axis might be a potential novel therapeutic target for OC.

PMID- 29169731 TI - A composition of medicinal plants with an enhanced ability to suppress microsomal lipid peroxidation and a protective activity against carbon tetrachloride-induced hepatotoxicity. AB - Treatment of liver injury induced by various toxicants represents a serious clinical challenge. Here, we utilized the ability of natural agents to inhibit microsomal lipid peroxidation (LPO) as the in-vitro screening paradigm for selecting efficacious tissue-protective combinations of cooperatively acting medicinal plants. Based on screening of 70 water-ethanol extracts obtained from different parts of 65 plants we prepared a highly active phytocomposition (PC-1) containing oregano (Origanum vulgare), wild thyme (Thymus serpyllum) and coltsfoot (Tussilago farfara) aerial parts, valerian (Valeriana officinalis) leaves and little-leaf linden (Tilia cordata) flowers. PC-1 extract exhibited the strongest anti-PLO and antihemolytic effects in vitro compared to those of the individual plants and other compositions tested. Using luciferase reporter assay and Western blotting in HepG2 human hepatocellular carcinoma cells, we found that PC-1 extract activated the Nrf2/antioxidant response element signaling pathway more effectively than the extracts of other phytocompositions. Importantly, oral administration of PC-1 extract (100-200 mg/kg) markedly ameliorated liver injury in rats acutely or chronically intoxicated by carbon tetrachloride. This was evidenced by improved liver histology, blood chemistry parameters, and microsomal LPO status and superoxide dismutase activity. In addition, treatment with PC-1 extract salvaged the osmotic resistance of erythrocytes in carbon tetrachloride intoxicated rats. Collectively, these data support the strategy of in-vitro plant selection for developing efficacious tissue-protective phytocompositions. PMID- 29169732 TI - MicroRNA-4465 suppresses tumor proliferation and metastasis in non-small cell lung cancer by directly targeting the oncogene EZH2. AB - MicroRNA-26 (miR-26) has been reported to be connected with tumor progression. MicroRNA-4465 (miR-4465) was one member of miR-26 family, however, the role of miR-4465 in non-small cell lung cancer (NSCLC) was unknown. This study was aimed to explore the function of miR-4465 and investigate whether miR-4465 can be a potential target for treating human NSCLC. QRT-PCR was applied to evaluate the miR-4465 expression levels in NSCLC cells. Then, we demonstrated the role of miR 4465 in NSCLC cells biological characteristics through detecting proliferation, migration and invasion. Luciferase reporter assay and TargetScan were applied to explore the potential target gene of miR-4465. In this study, we found that the miR-4465 expression levels in NSCLC cell lines were significantly reduced when compared to the normal human bronchial epithelial cell lines. And, over expression of miR-4465 could restrain the proliferation, migration and invasion of NSCLC. Moreover, MiR-4465 reduced EZH2 protein expression through the binding sites in 3' -UTR of the EZH2 mRNA, indicating EZH2 may be a direct target gene of miR-4465. Conclusively, miR-4465 suppressed cancer cells proliferation and metastasis by directly targeting the oncogene EZH2 and it may serve as a new potential therapeutic target in NSCLC. PMID- 29169733 TI - Use of Copaifera multijuga for acute corneal repair after chemical injury: A clinical, histopathological and toxicogenetic study. AB - Copaiba oil is widely used in medicine, but there are no reports regarding its application in ophthalmology. Therefore, the objective of this study was to evaluate the clinical, histopathological and toxicogenetic effects of eye drops containing 0.1 and 0.5% of Copaifera multijuga Hayne oil on superficial corneal ulcers induced with alkali in the left eye of rats. For histological analysis, the percent reduction in ulcers and thickness of the corneal epithelium and stroma were evaluated 48 and 72 h after ulcer induction. Additionally, neovascularization and polymorphonuclear infiltration were classified in the stroma. The bone marrow micronucleus test was used for toxicogenetic assessment. None of the animals exhibited clinical signs of immediate ocular discomfort after instillation and the eye drops were harmless to the ocular surface. There was a significant difference in percent ulcer reduction and corneal stroma thickness between animals treated with the C. multijuga eye drops and untreated animals with corneal injury and the negative control, respectively, suggesting a healing effect of the oleoresin. Analysis of the thickness of the corneal epithelium at the two time points showed that the eye drops formulated did not significantly reduce the damage caused by alkali. The same was observed for the treatments with the reference drugs. No difference in stromal neovascularization or inflammatory infiltration was observed between the treated groups. The toxicogenetic results revealed the absence of cytotoxicity and genotoxicity of the treatments. In conclusion, the C. multijuga eye drops did not cause damage to the ocular surface under the present experimental conditions and corneal epithelization was similar to the conventional treatments. These results indicate that eye drops containing C. multijuga oleoresin are a promising option for the treatment of superficial keratitis.

PMID- 29169735 TI - Associations of Clinically Relevant Levels of Depressive Symptoms and Antidepressant Use With Mortality in African American Health. AB - BACKGROUND: The Institute of Medicine has highlighted unequal treatment for African American individuals in health care. We examined the association of underuse of antidepressants in African American individuals with increased mortality. METHODS: We conducted a longitudinal cohort study in Metropolitan St Louis, Missouri, in a population-based study of community-dwelling African American individuals, aged 52 to 68 years. Medication evaluations and clinically relevant levels of depressive symptoms (CRLDS) assessments occurred in 2000 and 2004. The analytic sample included 830 (of 853 total, 97%) participants with complete data. CRLDS was defined as >=9 on the 11-item Center for Epidemiologic Studies Depression scale. Antidepressant use was determined by in-home medication recording and in-center coding. Participants were placed into 4 exposure categories: persistent CRLDS-no antidepressant (n = 69); intermittent CRLDS-no antidepressant (n = 123); antidepressant treatment (n = 110); and no CRLDS-no antidepressant (n = 528). Logistic regression with backwards elimination of the 9 identified potential confounders was used to examine associations of exposures with all-cause mortality over 6 years (2004-2010). Five sensitivity analyses investigated robustness of the primary findings. RESULTS: The antidepressant group was independently associated with reduced mortality compared with the persistent-no antidepressant group (odds ratio [OR] 0.19, 95% confidence interval [CI] 0.08-0.44). Sensitivity analyses showed no substantive differences from the primary model; one indicated that the persistent CRLDS-no antidepressant group experienced significantly increased mortality compared with the no CRLDS-no antidepressant group (OR 2.12, 95% CI 1.10-4.09), whereas the intermittent-no antidepressant group did not (OR 0.83, 95% CI 0.44-1.58). CONCLUSIONS: These results highlight that underuse of antidepressants in African American individuals is associated with increased mortality.

AB - RATIONALE: The prevalence of chronic obstructive pulmonary disease (COPD) and its associated comorbidities increase with age. However, little is understood about differences in the disease in patients over 65 years of age compared with younger patients. OBJECTIVES: To determine disease characteristics of COPD and its impact in older patients compared with younger patients. METHODS: We examined baseline characteristics of patients with COPD (global obstructive lung disease stage II IV) in 2 large cohorts: Genetic Epidemiology of COPD Study (COPDGene) and Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints (ECLIPSE). We compared demographics, indices of disease severity, prevalence of comorbidities, exacerbation frequency, and quality of life scores in patients >=65 years of age vs patients <65 years of age. We also tested for associations of age with disease characteristics and health outcomes. RESULTS: In the COPDGene cohort, older patients (n = 1663) had more severe disease as measured by forced expiratory volume in 1 second (1.22 vs 1.52 L, P < .001), use of long-term oxygen therapy (35% vs 22%, P < .001), 6-minute walk distance (355 vs 375 m, P < .001), and radiographic evidence of emphysema (14% vs 8%, P < .001) and air trapping (47% vs 36%, P < .001) and were more likely to have comorbidities compared with younger patients (n = 2027). Similarly, in the ECLIPSE cohort, older patients (n = 1030) had lower forced expiratory volume in 1 second (1.22 vs 1.34 L, P < .001), greater use of long-term oxygen therapy (7% vs 5%, P = .02), shorter 6- minute walk distance (360 vs 389 m, P < .001), and more radiographic evidence of emphysema (17% vs 14%, P = .009) than younger patients (n = 1131). In adjusted analyses of both cohorts, older age was associated with decreased frequency of exacerbations [odds ratio = 0.52, 95% confidence interval (CI) = 0.43-0.64 in COPDGene, odds ratio = 0.79, 95% CI = 0.64-0.99 in ECLIPSE] and a better quality of life (lower St. Georges respiratory questionnaire score) (beta = -8.7, 95% CI = -10.0 to -7.4 in COPDGene, beta = -4.4, 95% CI = -6.1 to -3.2 in ECLIPSE). CONCLUSIONS: Despite greater severity of illness, older patients with COPD had better quality of life and reported fewer exacerbations than younger patients. Although this observation needs to be explored further, it may be related to the fact that older patients change their expectations and learn to adapt to their disease.

PMID- 29169742 TI - A Decade of JAMDA. PMID- 29169741 TI - Utilization of Antibiotics in Long-Term Care Facilities in British Columbia, Canada. AB - BACKGROUND: Antibiotic use is highly prevalent in long-term care facilities (LTCFs); a resident's annual exposure to at least 1 course of antibiotic is approximately 50% to 80%. The objective of this study was to understand the extent of antibiotic use in the population of residents in British Columbia's (BC) LTCFs from 2007 to 2014. METHODS: Antibiotic prescription data for LTCF residents was extracted from the central prescription database and linked to the physician billing plan to obtain antibiotic indication. Total defined daily dose (DDD) per 1000 residents per day was calculated. RESULTS: Our database had 381 LTCFs with an average of nearly 24,694 residents annually and 419,036 antibiotic prescriptions. Antibiotic utilization did not change dramatically between 2007 and 2014, ranging from 39.2 in 2007 to 35.2 DDD per 1000 residents per day in 2014. Although usage of most antibiotics declined, use of moxifloxacin, amoxicillin-clavulanate, doxycycline, and amoxicillin increased significantly. The indication most frequently linked to prescription was urinary tract infection (6.58 DDD per 1000 residents per day), with nitrofurantoin, ciprofloxacin, and trimethoprim/sulfamethoxazole being the most commonly prescribed agents. This was followed closely by prescriptions for respiratory infections (5.34 DDD per 1000 residents per day), with moxifloxacin being the most commonly prescribed antibiotic, primarily for upper respiratory tract infection (URTI), whereas doxycycline is used commonly for lower respiratory tract infection. Duration of antibiotic therapy in LTCF residents has decreased significantly from 9.29 days to 7.3 days per prescription in 2014. CONCLUSION: Antibiotic use in LTCFs is high relative to the general population. Our study underscores that stewardship in LTCFs should continue to focus on length of treatment, appropriate detection of urinary tract infections, and avoidance of treating URTIs with antibiotics.

PMID- 29169740 TI - Redefining Cut-Points for High Symptom Burden of the Global Initiative for Chronic Obstructive Lung Disease Classification in 18,577 Patients With Chronic Obstructive Pulmonary Disease. AB - BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) can be classified into groups A/C or B/D based on symptom intensity. Different threshold values for symptom questionnaires can result in misclassification and, in turn, different treatment recommendations. The primary aim was to find the best fitting cut-points for Global initiative for chronic Obstructive Lung Disease (GOLD) symptom measures, with an modified Medical Research Council dyspnea grade of 2 or higher as point of reference. METHODS: After a computerized search, data from 41 cohorts and whose authors agreed to provide data were pooled. COPD studies were eligible for analyses if they included, at least age, sex, postbronchodilator spirometry, modified Medical Research Council, and COPD Assessment Test (CAT) total scores. MAIN OUTCOMES: Receiver operating characteristic curves and the Youden index were used to determine the best calibration threshold for CAT, COPD Clinical Questionnaire, and St. Georges Respiratory Questionnaire total scores. Following, GOLD A/B/C/D frequencies were calculated based on current cut-points and the newly derived cut-points. FINDINGS: A total of 18,577 patients with COPD [72.0% male; mean age: 66.3 years (standard deviation 9.6)] were analyzed. Most patients had a moderate or severe degree of airflow limitation (GOLD spirometric grade 1, 10.9%; grade 2, 46.6%; grade 3, 32.4%; and grade 4, 10.3%). The best calibration threshold for CAT total score was 18 points, for COPD Clinical Questionnaire total score 1.9 points, and for St. Georges Respiratory Questionnaire total score 46.0 points. CONCLUSIONS: The application of these new cut-points would reclassify about one-third of the patients with COPD and, thus, would impact on individual disease management. Further validation in prospective studies of these new values are needed.

PMID- 29169744 TI - The neuropathology of multiple system atrophy and its therapeutic implications. AB - Multiple system atrophy (MSA) is a fatal neurodegenerative disorder characterized by the abnormal accumulation of toxic forms of the synaptic protein alpha synuclein (alpha-syn) within oligodendrocytes and neurons. The presence of alpha syn within oligodendrocytes in the form of glial cytoplasmic inclusions is the diagnostic hallmark of MSA. However, it has been postulated that alpha-syn is produced in neurons and propagates to oligodendrocytes, where unknown mechanisms lead to its accumulation. The presence of alpha-syn within neurons in MSA has not been so extensively studied, but it may shed light into neuropathological mechanisms leading to oligodendroglial accumulation. Here we summarize the principal neuropathological events of MSA, and discuss how a deeper knowledge of these mechanisms may help develop effective therapies targeting alpha-syn accumulation and spreading. PMID- 29169746 TI - Simulations of simple Bovine and Homo sapiens outer cortex ocular lens membrane models with a majority concentration of cholesterol. AB - The lipid composition of bovine and human ocular lens membranes has been probed, and a variety of lipids have been found including phosphatidylcholine (PC), phosphatidylethanolamine (PE), sphingomyelin (SM), and cholesterol (CHOL) with cholesterol being present in particularly high concentrations. In this study, we use the all-atom CHARMM36 force field to simulate binary, ternary, and quaternary mixtures as models of the ocular lens. High concentration of cholesterol, in combination with different and varying diversity of phospholipids (PL) and sphingolipids (SL), affect the structure of the ocular lens lipid bilayer. The following analyses were done for each simulation: surface area per lipid, component surface area per lipid, deuterium order parameters (SCD), electron density profiles (EDP), membrane thickness, hydrogen bonding, radial distribution functions, clustering, and sterol tilt angle distribution. The SCD show significant bilayer alignment and packing in cholesterol-rich bilayers. The EDP show the transition from liquid crystalline to liquid ordered with the addition of cholesterol. Hydrogen bonds in our systems show the tendency for intramolecular interactions between cholesterol and fully saturated lipid tails for less complex bilayers. But with an increased number of components in the bilayer, the acyl chain of the lipids becomes a less important characteristic, and the headgroup of the lipid becomes more significant. Overall, cholesterol is the driving force of membrane structure of the ocular lens membrane where interactions between cholesterol, PL, and SL determine structure and function of the biomembrane. The goal of this work is to develop a baseline for further study of more physiologically realistic ocular lens lipid membranes.

PMID- 29169748 TI - Ascending aortic size in aortic coarctation depends on aortic valve morphology: Understanding the bicuspid valve phenotype. AB - BACKGROUND: In roughly half of patients with coarctation of the aorta (CoA), the aorta may be enlarged. It is uncertain whether enlargement is independent of aortic valve morphology. We sought to compare aortic size in CoA with a tricuspid valve (TAV) to those with bicuspid aortic valve (BAV). METHODS: Sixty-eight CoA patients and 20 healthy controls with prior cardiac magnetic resonance (CMR) imaging were included. CMR was retrospectively reanalyzed to measure aortic root and mid-ascending aorta. The maximum aortic diameter was compared between CoA with TAV, CoA with BAV, and control groups. RESULTS: CoA with TAV patients (n=27) had smaller aortic root diameters than CoA with BAV (n=41) (32+/-4.9 vs. 37+/ 5.8mm, p=0.001), despite being older (40 vs. 32years, p=0.01). Similarly, TAV CoA patients had a smaller mid-ascending aortic diameter (28+/-4.5 vs. 33+/-6.9mm, p=0.019) than BAV patients. TAV CoA was similar to controls in all metrics. Twenty-four patients (35%) with CoA had dilated aortas (>37mm), of which 79% had BAV. A history of hypertension did not predict larger aortic root or mid ascending aortic dimensions. CONCLUSIONS: In patients with CoA, TAV is associated with smaller aortic size compared to those with BAV, and similar to healthy controls. Aortic size in CoA is independent of hypertension. Therefore, aortopathy associated with BAV is likely a reflection of the BAV phenotype rather than CoA or its physiologic effects. This distinction may have implications for the frequency and types of monitoring and treatment of CoA patients. PMID- 29169749 TI - Comprehensive assessment of sex hormones in Takotsubo syndrome. AB - BACKGROUND: The detailed pathomechanism of Takotsubo syndrome (TS) is still elusive. Due to the predominance of postmenopausal females, a potential role of sex hormones has been suggested. However, the limited available data are contradictory. The aim of this study was to comprehensively assess the role of sex hormone levels in a large cohort of TS patients. METHODS: Serum samples of 57 female TS patients and 57 female patients with myocardial infarction (MI), matched for age (+/-2years) and repolarization disturbances were analyzed for estradiol (E2), estrone (E1), testosterone and androstenedione using liquid chromatography-tandem mass spectrometry. RESULTS: There was no difference concerning the concentrations of E1 [pmol/l (IQR): 89.1 (62.5, 132.0) vs. 98.8 (63.3, 156.0), p=0,441], testosterone [nmol/l (IQR): 0.67 (0.46, 1.00) vs. 0.80 (0.49, 1.08), p=0.382] and androstenedione [nmol/l (IQR): 2.03 (1.57, 3.11) vs. 2.98 (1.48, 5.27), p=0.244] between female TS and MI patients. Regarding E2, the majority of patients demonstrated concentrations below the detection limit of 30pmol/l (TS: n=41/54, 75.9%; MI: n=32/53, 60.4%; p=0.078). The remaining individuals with detectable E2 concentrations did not show a significant difference between TS and MI patients [pmol/l (IQR): 40.5 (33.0, 53.3) vs. 54.1 (37.9, 60.9); p=0.20]. CONCLUSIONS: Altered sex hormone levels, especially an estradiol deficiency, could not be identified as a risk factor for TS.

PMID- 29169751 TI - Selecting the right defibrillator in the younger patient: Transvenous, epicardial or subcutaneous? AB - The advent of the subcutaneous implantable cardioverter-defibrillator (SQ-ICD) provides an alternative to transvenous and epicardial ICD therapy. Particularly germane to the young patient with congenital heart disease or inheritable arrhythmia syndromes, the SQ-ICD may be ideal for those who do not require permanent cardiac pacing. The serious complications associated with transvenous ICD systems are largely driven by the intravascular components of these devices and are avoided by this extravascular technique. Multiple clinical trials have shown that SQ-ICDs are effective in detecting and terminating ventricular arrhythmias, yet nuanced issues must be considered, especially in the context of congenital cardiovascular anomalies. This review aims to contextualize the role of this technology in contrast with traditional ICDs, and provide a logical approach to appropriate device selection. PMID- 29169752 TI - Vigorous exercise in patients with hypertrophic cardiomyopathy. AB - BACKGROUND: We aimed to investigate if history of vigorous exercise was associated with changes in left ventricular morphology, left ventricular function and ventricular arrhythmias (VAs) in hypertrophic cardiomyopathy genotype positive, phenotype negative (Genotype+ LVH-) and in phenotype positive (HCM LVH+). METHODS: In this cross sectional study we included 187 subjects (age 49+/ 16years, 89(48%) female, 121(65%) HCM LVH+ and 66 (35%) Genotype+ LVH-) who answered a questionnaire on physical activity history. Exercise >=6 metabolic equivalents was defined as vigorous. Subjects with a history of vigorous exercise >=4h/week during >=6years were defined as athletes. All underwent echocardiography and Holter monitoring. VAs were defined as aborted cardiac arrest, sustained or non-sustained ventricular tachycardia. RESULTS: In both Genotype+ LVH- and HCM LVH+, lifetime vigorous exercise correlated with larger left ventricular end-diastolic volume (rho 0.44 and 0.38 respectively, both p<0.001). Lifetime vigorous exercise correlated with increased left ventricular mass in Genotype+ LVH- (rho 0.28, p=0.03), but not in HCM LVH+ (p=0.53). Left ventricular systolic function was similar between athletes and non-athletes in Genotype+ LVH- and HCM LVH+. HCM LVH+ athletes had lower E/e' (p=0.03) and higher e' (p=0.02) compared to non-athletes, while this difference was not observed in Genotype+ LVH-. Lifetime vigorous exercise was similar among HCM LVH+ with and without VAs (p=0.89). CONCLUSIONS: Increased lifetime vigorous exercise was associated with larger left ventricular volumes in hypertrophic cardiomyopathy, but correlated to left ventricular mass only in Genotype+ LVH-. Vigorous exercise was associated with favorable diastolic function in HCM LVH+, and was not associated with VAs. PMID- 29169753 TI - Trends and predictors of non-cardiovascular death in patients hospitalized for acute heart failure. AB - BACKGROUND: Little information is available on non-cardiovascular (CV) death in acute heart failure (AHF) patients. The present study determined the incidence, time course, and factors associated with long-term non-CV death in AHF patients in a real-world setting. METHODS: The ATTEND registry, a nationwide, prospective observational multicenter cohort study, included 4842 consecutive patients hospitalized for AHF. The primary endpoint of the present study was non-CV death. RESULTS: Median follow-up duration from admission was 513 (range, 385-778) days. Over the study period, 1183 patients died; 356 deaths (30.1%) were non-CV related. The proportion of non-CV deaths increased in the later follow-up phase (0-180days, 26.7%; 181-360days, 38.4%; >360days, 36.6%, p<0.001). After adjustment for all variables at baseline, age (hazard ratio [HR] 1.6 per decade, p<0.001) and non-cardiac comorbidities including chronic obstructive pulmonary disease (HR 1.58, p=0.003), history of stroke (HR 1.44, p=0.011), renal insufficiency (HR 1.07, per 10ml/min/1.73m2 decrease in estimated glomerular filtration, p=0.015), and hemoglobin (HR 1.15 per 1.0g/dl decrease, p<0.001) were strongly associated with non-CV death. Other predictors included ischemic etiology (HR 1.33, p=0.023), prior hospitalization for heart failure (HR 1.34, p=0.017), C-reactive protein (HR 1.04, p<0.001), and statin use (HR 0.70, p=0.016). CONCLUSIONS: The incidence of non-CV death was high in patients with AHF, accounting for 30% of long-term mortality. Furthermore, the proportion of non-CV death increased in the later follow-up phase. Better understanding of non CV death and more comprehensive treatment of non-CV comorbidities are vital to further improving prognosis in AHF patients. PMID- 29169754 TI - Chronic lower-dose relaxin administration protects from arrhythmia in experimental myocardial infarction due to anti-inflammatory and anti-fibrotic properties. AB - BACKGROUND: The peptide hormone relaxin-2 (RLX) exerts beneficial effects during myocardial ischemia, but functional data on lower-dose RLX in myocardial infarction (MI) is lacking. Therefore, we investigated the impact of 75MUg/kg/d RLX treatment on electrical vulnerability and left ventricular function in a mouse model of MI. METHODS AND RESULTS: Standardized cryoinfarction of the left anterior ventricular wall was performed in mice. A two week treatment period with vehicle or RLX via subcutaneously implanted osmotic minipumps was started immediately after MI. The relaxin receptor RXFP1 was expressed on ventricular/atrial cardiomyocytes, myofibroblasts, macrophages and endothelial but not vascular smooth muscle cells of small coronary vessels. RLX treatment resulted in a significant reduction of ventricular tachycardia inducibility (vehicle: 91%, RLX: 18%, p<0.0001) and increased epicardial conduction velocity in the left ventricle and borderzone. Furthermore, left ventricular function following MI was improved in RLX treated mice (left ventricular ejection fraction; vehicle: 41.1+/-1.9%, RLX: 50.5+/-3.5%, p=0.04). Interestingly, scar formation was attenuated by RLX with decreased transcript expression of connective tissue growth factor. Transcript levels of the pro-inflammatory cytokines interleukin-6 and interleukin-1beta were upregulated in hearts of vehicle treated animals compared to mice without MI. Application of RLX attenuated this inflammatory response. In addition, macrophage infiltration was reduced in the borderzone of RLX treated mice. CONCLUSION: Treatment with lower dose RLX in mice prevents post-infarction ventricular tachycardia due to attenuation of scar formation and cardiac inflammation. Therefore, RLX could be evaluated as new therapeutic option in the treatment of MI. PMID- 29169755 TI - Vigorous exercise in hypertrophic cardiomyopathy: Benefits may outweigh the risks.

PMID- 29169757 TI - Hs-cTroponins for the prediction of recurrent cardiovascular events in patients with established CHD - A comparative analysis from the KAROLA study. AB - BACKGROUND: High-sensitivity Troponins (hs-cTnT and hs-cTnI) are established biomarkers to identify patients with an acute myocardial infarction. However, data comparing the capacity of these two subtypes in predicting recurrent cardiovascular disease (CVD) events in a population with stable coronary heart disease (CHD) after adjustment for several other modern biomarkers are lacking. METHODS: We measured both troponins at baseline in 1068 CHD patients, followed them for 13years, assessed a combined CVD endpoint, and adjusted for multiple traditional and novel risk factors. RESULTS: Both troponins correlated significantly with age, low and high BMI, male gender, statin therapy, and emerging biomarkers (e.g. cystatin C, NT-proBNP, GDF-15, hsCRP or galectin 3). During follow-up of 13years, 267 fatal and non-fatal CVD events occurred. Top quartiles of both troponin concentrations were significantly associated with CVD events compared to the bottom quartile after adjustment for age, gender and established CVD risk factors (hs-cTnT: hazard ratio (HR) 2.54 (95% CI, 1.60 4.03), p for trend: <0.0001; hs-cTnI: HR 2.20 (95% CI, 1.44-3.36), p for trend: <0.0002 and 0.0003). However, after adjustment for other emerging biomarkers, the associations were no longer statistically significant (hs-cTnT: HR 1.63 (95% CI, 0.97-2.73), p for trend: 0.17; hs-cTnI: HR 1.61 (95% CI, 1.00-2.60), p for trend: 0.067). CONCLUSION: Both troponins are reliable biomarkers of recurrent cardiovascular events, especially if other novel, important markers such as NT proBNP, GDF-15 and galectin 3 are not available. Nevertheless, a further workup is still needed to explain the complex interaction of biomarkers indicating vascular and myocardial function.

PMID- 29169759 TI - Abnormal coronary vasoreactivity in transient left ventricular apical ballooning (tako-tsubo) syndrome. AB - BACKGROUND: The exact etiology and pathophysiologic mechanisms of tako-tsubo syndrome (TTS) remain controversial. OBJECTIVE: To further evaluate the abnormal coronary vasoreactivity and its possible anatomical substrate in TTS. METHODS: We studied 47 patients (46 women; age 67+/-12years) who underwent diagnostic cardiac catheterization and evaluation of coronary vasoreactivity by sequential acetylcholine (Ach), nitroglycerine and adenosine testing with angiographic and intracoronary pressure-Doppler flow monitoring. Coronary artery wall morphology was also evaluated by intravascular ultrasound (IVUS) imaging in 45 vessels of 43 patients. RESULTS: Abnormal coronary vasoconstriction to Ach stimulation was elicited in 40 patients (85%) involving the LAD artery and its branches in 39 (83%). Abnormal microvascular function was seen in 39 (83%) patients. Overall, hyperemic microvascular resistance index (HMR) was higher and Doppler coronary flow velocity reserve (CFVR) was lower in the LAD artery territory as compared to the reference territories (2.64+/-1.23 vs 2.05+/-0.56; p=0.008 and 1.95+/-0.7 vs 2.3+/-0.6; p=0.018, respectively). IVUS revealed no plaque rupture, dissection or thrombosis but occult plaque formation and myocardial bridging were found as a possible anatomical substrate of endothelial dysfunction in 67% and 48.8% patients respectively. CONCLUSIONS: A global failure of coronary vasomotor function was demonstrated in most TTS patients. These findings implicate abnormal vasoconstrictive response to the activation of the sympathetic system as a potential mechanism involved in the pathogenesis of myocardial stunning in TTS. PERSPECTIVES: Competency in medical knowledge: Abnormal coronary vasoconstriction secondary to endothelial dysfunction may actively contribute to the clinical manifestation of acute coronary syndromes in patients with non-obstructive coronary disease. Translational outlook 1: TTS patients reveal a global failure of vasomotor function with both vasoconstrictive response to acetylcholine and increased hyperemic microvascular resistances in the territory of myocardial stunning. They may also show occult coronary atherosclerosis and myocardial bridging as the anatomic substrates of endothelial dysfunction. Translational outlook 2: The cardiac phenotype of TTS includes a high prevalence of coronary vasomotor disturbances. These findings implicate abnormal vasoconstrictive response to the activation of the sympathetic system as a potential mechanism involved in the pathogenesis of TTS in post-menopausal women. Thus, a systematic evaluation of coronary vasoreactivity could better characterize the syndrome.

AB - BACKGROUND: Skin cancers (SC) are complex diseases that develop from complex combinations of genetic and environmental risk factors. One of the most severe and rare genetic diseases predisposing to SC is the Xeroderma pigmentosum (XP) syndrome. OBJECTIVES: First, to identify the genetic etiology of XP and to better classify affected patients. Second, to provide early molecular diagnosis for pre symptomatic patient and finally to offer genetic counseling for related individuals. METHODS: Whole Exome Sequencing (WES) and Run Of Homozygosity (ROH) were performed for two patients belonging to two different multiplex consanguineous families. The identified mutations were confirmed by Sanger sequencing and researched in ten Tunisian families including a total of 25 affected individuals previously suspected as having XP group V (XP-V) form. All patients had mild dermatological manifestations, absence of neurological abnormalities and late onset of skin tumors. RESULTS: Screening for functional variations showed the presence of the ERCC2 p.Arg683Gln in XP14KA-2 patient and a novel mutation, DDB2 p. (Lys381Argfs*2), in XP51-MAH-1 patient. Sanger sequencing and familial segregation showed that the ERCC2 mutation is present at a homozygous state in 10 affected patients belonging to 3 families. The second mutation in DDB2, is present at a homozygous state in 5 affected cases belonging to the same family. These two mutations are absent in the remaining 10 affected patients. The ERCC2 c.2048G > A mutation is present in a medium ROH region (class B) suggesting that it mostly arises from ancient relatedness within individuals. However, the c.1138delG DDB2 mutation is present in a large ROH region (class C) suggesting that it arises from recent relatedness. CONCLUSION: To our knowledge, this is the first study that identifies XP-D and XP-E complementation groups in Tunisia. These two groups are very rare and under-diagnosed in the world and were not reported in North Africa. PMID- 29169767 TI - School Environment Is Related to Lower Health and Safety Risks Among Sexual Minority Middle and High School Students. AB - PURPOSE: The objective of this study was to examine the relationship between school involvement and connectedness with measures of sexual risk, substance use, and experience of violence among students who had sexual contact with the same sex or with both sexes. METHODS: A sample of middle school and high school students who participated in a study conducted in a large urban school district were selected based on their reported experience of having initiated sexual activity with same-sex partners. In classroom-based surveys, we assessed self reported involvement in school-based activities and feelings of school connectedness, as well as self-reported sexual risk, substance use, and experience of violence. RESULTS: Significant protective associations were found between school involvement and lifetime alcohol and marijuana use, and between school connectedness and ever having been in a fight, feeling safe at school, and drug use other than marijuana (all p < .05). CONCLUSIONS: Findings suggest that efforts to increase school involvement and connectedness provide a starting point for addressing significant health and safety concerns among students with same sex sexual activity.

AB - Transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) is the first area of interventional cardiology where women are treated as often as men. In this analysis of the gender specific results of randomised controlled trials (RCTs) comparing TAVI with surgical aortic valve replacement (SAVR) we aimed to determine whether gender affects the survival comparison between TAVI and SAVR. We identified all RCTs comparing TAVI versus SAVR for severe AS and reporting 1 and/or 2year survival. Summary odds ratios (ORs) were obtained using a random-effects model. Heterogeneity was assessed using the Q statistic and I2. Four RCTs met the criteria, totalling 3758 patients, 1706 women and 2052 men. Amongst females, TAVI recipients had a significantly lower mortality than SAVR recipients, at 1year (OR 0.68; 95%CI 0.50 to 0.94) and at 2years (OR 0.74; 95%CI 0.58 to 0.95). Amongst males there was no difference in mortality between TAVI and SAVR, at 1year (OR 1.09; 95%CI 0.86 to 1.39) or 2years (OR 1.05; 95%CI 0.85 to 1.3). The difference in treatment effect between genders was significant at both 1year (pinteraction=0.02) and 2years (pinteraction=0.04). In women TAVI has a 26 to 31% lower mortality odds than SAVR. In men, there is no difference in mortality between TAVI and SAVR. PMID- 29169768 TI - Increasing Patient Portal Usage: Preliminary Outcomes From the MyChart Genius Project. AB - PURPOSE: To determine the feasibility, acceptability, and preliminary effectiveness of dedicating staff ("MyChart Geniuses") to assist adolescents with patient portal sign-up; to examine patient satisfaction with MyChart Genius services; and to determine patient preferences for future communications related to health issues. METHODS: Adolescent patients (13-25 years old) in an urban, academic, primary care clinic were approached by MyChart Genius staff to assist with enrolling in MyChart and downloading the MyChart mobile App. Patients were also invited to partake in a brief, online survey assessing their technology use and access, as well as their preferences surrounding communication with their health-care providers. Survey responses were analyzed using SPSS Statistics (SPSS Inc., Chicago, IL). RESULTS: Ninety-six patients were approached, 84 (87.5%) of whom enrolled in MyChart. Sixty-four adolescents agreed to answer survey questions. Respondents were primarily African-American patients (87%), with a mean age of 18.7 years. The majority (79%) of participants were either satisfied or very satisfied with the Genius program. The respondents reported high access to and use of basic technology, and a high perceived need for an electronic health record App. Preferences for future communications with health-care providers revealed population subsets, indicating an area to further individualize interventions. CONCLUSIONS: This is one of the first studies to examine a strategy to increase patient portal uptake and usage among minority, urban adolescents (a group with demonstrated preferences on communications with health-care providers). The presence of specially trained MyChart Genius staff is a feasible, effective, and patient-satisfactory method of engaging with this group of adolescents. PMID- 29169769 TI - Online denoising of eye-blinks in electroencephalography. AB - OBJECTIVE: Due to its high temporal resolution, electroencephalography (EEG) has become a broadly-used technology for real-time brain monitoring applications such as neurofeedback (NFB) and brain-computer interfaces (BCI). However, since EEG signals are prone to artifacts, denoising is a crucial step that enables adequate subsequent data processing and interpretation. The aim of this study is to compare manual denoising to unsupervised online denoising, which is essential to real-time applications. METHODS: Denoising EEG for real-time applications requires the implementation of unsupervised and online methods. In order to permit genericity, these methods should not rely on electrooculography (EOG) traces nor on temporal/spatial templates of the artifacts. Two blind source separation (BSS) methods are analyzed in this paper with the aim of automatically correcting online eye-blink artifacts: the algorithm for multiple unknown signals extraction (AMUSE) and the approximate joint diagonalization of Fourier cospectra (AJDC). The chosen gold standard is a manual review of the EEG database carried out retrospectively by a human operator. Comparison is carried out using the spectral properties of the continuous EEG and event-related potentials (ERP). RESULTS AND CONCLUSION: The AJDC algorithm addresses limitations observed in AMUSE and outperforms it. No statistical difference is found between the manual and automatic approaches on a database composed of 15 healthy individuals, paving the way for an automated, operator-independent, and real-time eye-blink correction technique. PMID- 29169770 TI - Fatal serotonin syndrome in a patient with Marchiafava-Bignami disease: Combined neurological and psychiatric emergency. AB - Marchiafava-Bignami disease (MBD) is a rare fatal neurological disorder characterized by demyelination, primary degeneration, and necrosis of the corpus callosum. Although MBD is mostly associated with chronic alcohol consumption and malnutrition, it has been reported in non-alcoholic patients. Serotonin syndrome is a rare but potentially fatal side effect of antidepressants that results from overstimulation of both central and peripheral serotonergic receptors. In this report, we present a case with fatal serotonin syndrome happening in a non alcoholic patient with the chronic form of MBD. To our knowledge, this case is the first report of fatal serotonin syndrome due to citalopram in an MBD patient. The present report may indicate that citalopram and other SSRIs should not be used in patients with MBD. Our case is also among few reported cases in the literature where no cause was identified in a patient with no previous history of alcohol intake. PMID- 29169771 TI - Antiurolithiatic activity of natural constituents isolated from Aerva lanata. AB - BACKGROUND: Pashanabheda is used as antiurolithiatic in Ayurveda. In the present study, Aerva lanata (L) Juss. ex. Schult (Amaranthaceae) from Western Ghats of India was selected for isolation of active constituents and screening for antiurolithiatic potentials. OBJECTIVE: Screening of compounds isolated from A. lanata for antiurolithiatic potentials. MATERIALS AND METHODS: Ethylene glycol (0.75% v/v) induced urolithiasis model was used to study the antiurolithiatic activity in male Wistar albino rats. The animals were divided into five groups containing six each. Based on the LD50 of the plant extract (2000 mg/kg b.w) equivalent dose was calculated from their yield. Two isolated compounds (quercetin and betulin) of A. lanata were screened for antiurolithiatic potentials in calculi induced (ethylene glycol 0.75% v/v) male Wistar albino rats by administering 2 mg/kg b.w/day orally as test dose for 28 days. RESULTS: The urine volume was found to be significantly increased from 12.76 +/- 0.10 ml to 21.35 +/- 0.20 ml in the rats treated by quercetin and 21.50 +/- 0.21 ml in rats treated by betulin. Urine microscopy revealed significant reduction (p < 0.001) in the size of calculi and significantly enhanced (p < 0.001) excretion of calcium, oxalate, phosphate, whereas the level of magnesium was increased. SEM of kidney sections has revealed reduction in the calculi in treated animals. Serum analysis has revealed significant reduction in the level of BUN and creatinine in treated rats. CONCLUSION: The isolated quercetin and betulin from A. lanata have shown mild diuretic effect as well as antiurolithiatic effect by significantly reducing the size of calculi in the kidneys and enhancing the excretion of calcium, phosphate, oxalate while maintaining the level of magnesium, which is reported to be one of the calculi inhibiting factors.

PMID- 29169774 TI - Sir Denis Browne, the father of modern pediatric surgery. AB - Sir Denis John Wolko Browne (1892-1967), while not the first in the British Isles to devote his entire surgical practice to pediatric surgery, is accepted as "the father of pediatric surgery in the United Kingdom." He made contributions to operations as varied as tonsillectomy, pyloromyotomy, and hypospadias repair, and provided fundamental insights into the proper treatment of club foot, congenital dislocation of the hip, and cryptorchidism. He introduced the transverse laparotomy incision, primary repair of congenital intestinal obstruction, and the end-to-back anastomosis for intestinal atresia, techniques so commonly used that it is difficult to think of pediatric surgical operations done any differently. In addition, he invented the elegant Denis Browne retractor that remains in use today, one of the few eponymic instruments known by its originator's first and last name. He was among the founders of the British Association of Pediatric Surgeons, one of the first professional organizations in the field, and served as its first president. His legendary status was enhanced by an acerbic temperament that often surfaced in an outspoken and uncompromising advocacy on the behalf of the proper care of children. A larger-than-life figure in pediatric surgery, Browne's legacy is so wide-ranging and enduring that his unofficial title has been broadened to "the father of modern pediatric surgery." PMID- 29169775 TI - In and out of schizophrenia: Activation and deactivation of the negative and positive schemas. AB - Theorists, clinicians, and investigators have attempted to find a common source for the negative and positive symptoms of schizophrenia. We propose that a unified theory, based on a common cognitive structure not only has explanatory value, but can serve as a framework for a psychotherapeutic intervention. Specifically, we propose that the cognitive triad - the negative view of the self, others, and the future - is the source of the content for the negative and positive symptoms. We report literature supporting the relationship between each facet of the negative triad and each of the key symptoms: expressive negative symptoms, delusions, and verbal hallucinations. We conclude that the literature supports the validity of the cognitive model of negative and positive symptoms. The cognitive model furthers the understanding of the positive and negative symptoms of schizophrenia, and we describe how this provides a framework for a psychotherapeutic intervention.

PMID- 29169777 TI - One-step FPLC-size-exclusion chromatography procedure for purification of rDMBT1 6 kb with increased biological activity. AB - Deleted in Malignant Brain Tumor 1 (DMBT1, alias SAG or gp340) is a pattern recognition receptor involved in immune defense, cell polarization, differentiation and regeneration. To investigate the role of the protein in physiological and pathological processes, the protein has often been isolated from saliva or produced in vitro and purified by a multistep affinity purification procedure using bacteria, followed by FPLC. Here, we compared a simple, one-step FPLC-SEC protocol for purification of recombinant DMBT1 6 kb, with that of the standard bacteria affinity purification-based protocol. Our data suggest that our FPLC-SEC protocol yields DMBT1 in a more native conformation. PMID- 29169778 TI - 15N CEST data and traditional model-free analysis capture fast internal dynamics of DJ-1. AB - Previous studies have shown that relaxation parameters and fast protein dynamics can be quickly elucidated from 15N-CEST experiments [1]. Longitudinal R1 and transverse R2 values were reliably derived from fitting of CEST profiles. Herein we show that 15N-CEST experiments and traditional modelfree analysis provide the internal dynamics of three states of human protein DJ-1 at physiological temperature. The chemical exchange profiles show the absence of a minor state conformation and, in conjunction with 1H-15N NOEs, show increased mobility. R1 and R2 values remained relatively unchanged at the three naturally occurring oxidation states of DJ-1, but exhibit striking NOE differences. The NOE data was, therefore, essential in determining the internal motions of the DJ-1 proteins. To the authors' knowledge, we present the first study that combines 15N CEST data with traditional model-free analyses in the study of a biological system and affirm that more 'lean' model-free approaches should be used cautiously.

PMID- 29169779 TI - Mind-Matter Interactions and the Frontal Lobes of the Brain: A Novel Neurobiological Model of Psi Inhibition. AB - CONTEXT: Despite a large literature on psi, which encompasses a range of experiences including putative telepathy (mind-mind connections), clairvoyance (perceiving distant objects or events), precognition (perceiving future events), and mind-matter interactions, there has been insufficient focus on the brain in relation to this controversial phenomenon. In contrast, our research is based on a novel neurobiological model suggesting that frontal brain systems act as a filter to inhibit psi and that the inhibitory mechanisms may relate to self awareness. OBJECTIVE: To identify frontal brain regions that may inhibit psi. DESIGN: We used mind-matter interactions to study psi in two participants with frontal lobe damage. The experimental task was to influence numerical output of a Random Event Generator translated into movement of an arrow on a computer screen to the right or left. Brain MRI was analyzed to determine frontal volume loss. RESULTS: The primary area of lesion overlap between the participants was in the left medial middle frontal region, an area related to self-awareness, and involved Brodmann areas 9, 10, and 32. Both participants showed a significant effect in moving the arrow to the right, i.e., contralateral to the side of primary lesion overlap. Effect sizes were much larger compared to normal participants. CONCLUSIONS: The medial frontal lobes may act as a biological filter to inhibit psi through mechanisms related to self-awareness. Neurobiological studies with a focus on the brain may open new avenues of research on psi and may significantly advance the state of this poorly understood field.

PMID- 29169782 TI - Radiation Segmentectomy versus Selective Chemoembolization in the Treatment of Early-Stage Hepatocellular Carcinoma. AB - PURPOSE: To compare outcomes of radiation segmentectomy (RS) and segmental transarterial chemoembolization in treatment of unresectable, solitary hepatocellular carcinoma (HCC) <= 3 cm. MATERIALS AND METHODS: From January 2012 to January 2016, 534 and 877 patients were treated with radioembolization and transarterial chemoembolization, respectively. A cohort of 112 (radiation segmentectomy [RS], 55; chemoembolization, 57) locoregional therapy-naive patients with solitary HCC <= 3 cm without vascular invasion or metastasis was retrospectively identified and stratified according to baseline patient demographics, tumor characteristics, and laboratory values. Propensity score matching (PSM) was conducted using a nearest neighbor algorithm (1:1). Outcomes analyzed included laboratory toxicities, imaging response, time to secondary therapy (TTST), and overall survival. RESULTS: Before PSM, complete response (CR) rate was 81.2% for RS and 49.1% for chemoembolization (odds ratio 2.2; 95% confidence interval [CI], 1.4-3.3; P < .001). Median (95% CI) TTST after initial therapy was 246 days (135-250 d) in chemoembolization group and 700 days (308-812 d) in RS group (hazard ratio 0.71; 95% CI, 0.55-0.92; P = .009). Overall survival before PSM was not significantly different between the 2 groups (P = .29). Overall CR rate after PSM was 92.1% in RS group and 52.6% in chemoembolization group (P = .005). Median (95% CI) TTST after matching was 161 days (76-350 d) in chemoembolization group and 812 days (363-812 d) in RS group (P = .001). Overall survival after matching was not significantly different between the 2 groups (P = .71). CONCLUSIONS: RS results in improved imaging response and longer TTST compared with transarterial chemoembolization in treatment of early-stage HCC. PMID- 29169783 TI - The 2017 Integrated IR Residency Match: Results of a National Survey of Applicants and Program Directors. AB - PURPOSE: To characterize and compare the experiences of matched applicants and program directors (PDs) participating in the first large-scale integrated interventional radiology (IR) residency match. MATERIALS AND METHODS: Survey questionnaires were distributed nationally to integrated IR applicants who matched in the 2017 Match cycle and PDs. Both groups were questioned regarding their experiences with the application, interview, rank, and match processes as well as applicant-specific and PD-specific information. Summary and descriptive statistics were applied to responses, and comparison of Likert scale responses was performed by two-sample t test. RESULTS: Sixty-one matched applicants (51.3%) and 34 PDs (55.7%) responded to the survey. Regarding the match process, applicants believed United States Medical Licensing Examination (USMLE) Step 1 score (P = .002) and connection to a program's geographic location (P = .006) were significantly more important than PDs did, whereas PDs ranked grades (P = .049), class rank (P = .011), academic awards (P = .003), additional degrees (P < .001), and USMLE Step 2 Clinical Skills score (P < .001) as significantly more important factors than applicants did. Additional information regarding demographic data, medical school experiences in IR, application strategies, interview experiences, rank lists, the intern year, and match results are reported. CONCLUSIONS: The completion of the first large-scale integrated IR match represents a paradigm shift in the way in which IR practitioners are recruited and trained. This study provides valuable benchmark data and analysis that can be used to improve efforts to match the best-fitting applicants into the integrated IR residency and improve future match cycles for applicants and PDs alike. PMID- 29169784 TI - Fast-Track Registration: A Way to Increase Efficiency in the IR Division. AB - PURPOSE: To evaluate changes in patient registration process at an academic 2 suite IR Division to determine if moving registration from the waiting room to the vascular holding area decreased amount of time patients spent in the Radiology Department and improved start times. MATERIALS AND METHODS: A data collection sheet was created by evaluating patient-related processes; event timestamps were recorded on the sheet. The control group consisted of 33 patients who registered using the traditional process. The fast-track group consisted of 29 patients who bypassed the traditional registration procedure and were registered by nurses in the vascular holding area. RESULTS: Total time between control and fast-track groups significantly decreased from an average time of 215 minutes to 178 minutes (P = .020). The average start time improved significantly from an average of 63 minutes after scheduled procedure start time for the control group to 33 minutes after the scheduled procedure start time for the fast track group (P = .009). Start time (P = .022), time spent in recovery area (P = .006), and total time, after correcting for differences in laboratory test turnaround time, (P = .010) decreased in variability after implementation of fast track registration. CONCLUSIONS: Implementing fast-track registration for outpatient subcutaneous port placement in the IR Division improved start times and decreased total time patients spent in the hospital, while also reducing variability in the process. PMID- 29169785 TI - [Parental alienation, child psychological abuse and DSM-5]. AB - Psychiatric experts find it is easier to deal with more horrible crimes than highly conflictual divorces. In the former, projections are impossible and "files" raise very interesting issues with regard to criminology; in contrast, in the latter the expert is confronted not just with a family but also and lest one forget, a couple that at one point in time had loved each other. However, the separation resembles a bloodbath. We will not detail the various psychiatric pathologies, which may further complicate a separation: they are well-known and, on a procedural level, do not raise any specific concerns. We will however address "pathological divorces" where although individuals, assessed on a case-by case basis, are exempt from ascertainable or developing psychiatric pathologies, pathology permeates systemic relations, inextricably linked to hatred or disgust. In this light, fault-based divorces still remain rare: it is in this context, marked by defiance and doubt as to the parental competence of each member of the couple that the psychiatric expert intervenes, with a similar acknowledged mission to that of the court: recommendations to be offered regarding visitation and custody rights. Amongst the conflictual and inextricable situations the most often encountered in expert practice, the parental alienation syndrome (PAS) now known as parental alienation (PA) refers to all psychopathological manifestations observed in children subject to highly conflictual parental separations, and above all, the unjustified or inexplicable rejection of a parent by a child (or even by siblings). This recent entity has raised controversy: some even go so far as to deny the existence itself of this phenomenon claiming that it does not appear in the international classifications of psychiatric disorders. Consequently, it was not included in the last edition of the DSM and does not appear in the ICD classification of the OMS whose 11th edition is currently being prepared. The weaknesses in the scientific concept and its purely passionate dimension, including sexist controversies, must be carefully elucidated in the dismissal or denial of this pathology. The author raises various definitions of parental alienation of which the most recent is undoubtedly the least controversial. He discusses the reasons for the dismissal of the concept by the Scientific Committee of the DSM-5. This dismissal is however quite apparent as although the term "parental alienation" is not contained therein, we will show that the notion is clearly referred to in at least two chapters of the new American classification of mental disorders. PMID- 29169786 TI - Characterization of cellulolytic microbial consortium enriched on Napier grass using metagenomic approaches. AB - Energy grass is a promising substrate for production of biogas by anaerobic digestion. However, the conversion efficiency is limited by the enzymatically recalcitrant nature of cellulosic wastes. In this study, an active, structurally stable mesophilic lignocellulolytic degrading microbial consortium (Np-LMC) was constructed from forest compost soil microbiota by successive subcultivation on Napier grass under facultative anoxic conditions. According to tagged 16S rRNA gene amplicon sequencing, increasing abundance of facultative Proteobacteria was found in the middle of batch cycle which was then subsequently replaced by the cellulose degraders Firmicutes and Bacteroidetes along with decreasing CMCase, xylanase, and beta-glucanase activity profiles in the supernatant after 5 days of incubation. Anaerobic/facultative bacteria Dysgonomonas and Sedimentibacter and aerobic bacteria Comamonas were the major genera found in Np-LMC. The consortium was active on degradation of the native and delignified grass. Direct shotgun sequencing of the consortium metagenome revealed relatively high abundance of genes encoding for various lignocellulose degrading enzymes in 23 glycosyl hydrolase (GH) families compared to previously reported cellulolytic microbial communities in mammalian digestive tracts. Enzymes attacking cellulose and hemicellulose were dominated by GH2, 3, 5, 9, 10, 26, 28 and 43 in addition to a variety of carbohydrate esterases (CE) and auxiliary activities (AA), reflecting adaptation of the enzyme systems to the native herbaceous substrate. The consortium identified here represents the microcosm specifically bred on energy grass, with potential for enhancing degradation of fibrous substrates in bioenergy industry. PMID- 29169787 TI - Comprehensive, blinded assessment of balance in orthostatic tremor. AB - INTRODUCTION: Orthostatic Tremor (OT) is a movement disorder characterized by a sensation of unsteadiness and tremors in the 13-18 Hz range present upon standing. The pathophysiology of OT is not well understood but there is a relationship between the sensation of instability and leg tremors. Despite the sensation of unsteadiness, OT patients do not fall often and balance in OT has not been formally assessed. We present a prospective blinded study comparing balance assessment in patients with OT versus healthy controls. METHODS: We prospectively enrolled 34 surface Electromyography (EMG)-confirmed primary OT subjects and 21 healthy controls. Participants underwent evaluations of balance by blinded physical therapists (PT) with standardized, validated, commonly used balance scales and tasks. RESULTS: OT subjects were mostly female (30/34, 88%) and controls were majority males (13/20, 65%). The average age of OT subjects was 68.5 years (range 54-87) and for controls was 69.4 (range 32-86). The average duration of OT symptoms was 18 years. OT subjects did significantly worse on all the balance scales and on most balance tasks including Berg Balance Scale, Functional Gait Assessment, Dynamic Gait Index, Unipedal Stance Test, Functional Reach Test and pull test. Gait speed and five times sit to stand were normal in OT. CONCLUSIONS: Common validated balance scales are significantly abnormal in primary OT. Despite the objective finding of impaired balance, OT patients do not commonly have falls. The reported sensation of unsteadiness in this patient population seems to be out of proportion to the number of actual falls. Further studies are needed to determine which components of commonly used balance scales are affected by a sensation of unsteadiness and fear of falling.

AB - In this review the usual methods applied in systematic reviews and meta-analyses are outlined. The ideal hypothesis for a systematic review should be generated by information not used later in meta-analyses. The selection of studies involves searching in web repertories, and more than one should be consulted. A manual search in the references of articles, editorials, reviews, etc. is mandatory. The selection of studies should be made by two investigators on an independent basis. Data collection on quality of the selected reports is needed, applying validated scales and including specific questions on the main biases which could have a negative impact upon the research question. Such collection also should be carried out by two researchers on an independent basis. The most common procedures for combining studies with binary outcomes are described (inverse of variance, Mantel-Haenszel, and Peto), illustrating how they can be done using Stata commands. Assessment of heterogeneity and publication bias is also illustrated with the same program. PMID- 29169793 TI - Proteomic evaluation of human umbilical cord tissue exposed to polybrominated diphenyl ethers in an e-waste recycling area. AB - Parental exposure to polybrominated diphenyl ethers (PBDEs) is associated with adverse birth outcomes. This study aims to examine differentially-expressed protein profiles in umbilical cord tissue, derived from mothers exposed to PBDEs, and investigate candidate biomarkers to reveal the underlying molecular mechanisms. Umbilical cord samples were obtained from women residing in an electronic waste (e-waste) recycling area (Guiyu) and reference area (Haojiang) in China. The concentration of PBDEs in umbilical cord tissue was determined by gas chromatography and mass spectrometry (GC/MS). Isobaric tagging for relative and absolute quantification (iTRAQ)-based proteomic technology was conducted to analyze differentially-expressed protein profiles. The total PBDE concentration was approximately five-fold higher in umbilical cords from Guiyu than from Haojiang (median 71.92ng/g vs. 15.52ng/g lipid, P<0.01). Neonatal head circumference, body-mass index (BMI) and Apgar1 score were lower in Guiyu and negatively correlated with PBDE concentration (P<0.01). Proteomic analysis showed 697 proteins were differentially expressed in the e-waste-exposed group compared with the reference group. The differentially-expressed proteins were principally involved in antioxidant defense, apoptosis, cell structure and metabolism. Among them, catalase and glutathione S-transferase omega-1, were down-regulated, and cytochrome c was found to be up-regulated, changes which were further verified by enzyme-linked immunosorbent assays. These results suggest that an antioxidant imbalance and cell apoptosis in the umbilical cord following PBDE exposure is associated with neonatal birth outcomes. PMID- 29169794 TI - FOCUS in Thoracic Surgery: Does Feasibility Mean Functionality? PMID- 29169795 TI - Paravertebral Block for Thoracic Surgery. AB - : Local anesthetic injected into a wedge-shaped space lateral to the spinal nerves as they emerge from the intervertebral foramina produces somatosensory and sympathetic nerve blockade effective for anesthesia and for managing pain of unilateral origin from the chest and abdomen. Paravertebral blockade (PVB) is versatile and may be applied unilaterally or bilaterally. Unlike thoracic epidural, the PVB technique may be used to avoid contralateral sympathectomy, thereby minimizing hypotension and leading to better preservation of blood pressure. There are no reports on systemic toxicity associated with bilateral PVB despite the need for relatively large doses of local anesthetics. This review includes an important historic background and captures the resurgence of PVB-an almost lost technique. Thoracic PVB provides post-thoracotomy pain relief comparable with thoracic epidural analgesia (TEA) with lower side effects supported by moderate-quality evidence. The feasibility and potential of bilateral thoracic PVB for bilateral thoracic surgery appear practical. However, there is existing controversy in the assumption that thoracic PVB is a satisfactory, safer alternative when anticoagulation status is a contraindication to thoracic epidural placement. During the last 2 decades of systematic reviews and meta-analyses, both TEA and PVB have been deemed appropriate in the management of thoracic surgery. A multimodal approach to analgesia includes regional techniques for thoracic surgery that may reduce the likelihood of the development of postoperative complications and chronic pain. PURPOSE OF THIS REVIEW: The authors evaluated current opinion, clinical practice, new multimodal adjuvants, regional anesthesia, and innovation and technology related PVB in the thoracic surgery patient population. The review focuses on history, techniques, application, ease of placement, and relative safety of this regional technique. For this review, studies and reference lists were retrieved from the Cochrane library, Embase, and Medline from January 1995 through January 2017. SUMMARY: Existing evidence demonstrates noninferiority of thoracic PVB compared with TEA for postoperative analgesia, with fewer side effects for unilateral and bilateral thoracic surgery, including video-assisted thoracoscopy. The determining factors in selecting the regional technique of choice include the following: (1) tolerance of side effects associated with TEA, (2) consensus on best practice or technique, and (3) operator experience. There is no consensus on the optimal approach for thoracic PVB technique or any standardization when comparing the landmark, ultrasound-guided, or stimulation-based PVB approaches. Moreover, the efficacy of TEA compared with PVB in preventing post-thoracotomy chronic pain syndrome has not been investigated thoroughly and requires future clinical trials. PMID- 29169796 TI - Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (POSSUM) System for Outcome Prediction in Elderly Patients Undergoing Major Vascular Surgery. AB - OBJECTIVE: POSSUM system is widely used and validated for 30-day mortality and morbidity prediction. The aim of this study was to evaluate the performance of five POSSUM's equations (POSSUM, P-POSSUM, V-POSSUM, V-POSSUM physiology and V POSSUM Cambridge) on predicting 30-day mortality and morbidity in elderly patients undergoing major elective vascular surgery. DESIGN: A retrospective longitudinal cohort study. SETTING: A study conducted at an University Hospital. PARTICIPANTS: 208 elderly patients (>= 60 years) undergoing major elective vascular surgery. MEASUREMENTS: Data collected from the clinical files included patient's characteristics, diagnosis, surgery, comorbidities, parameters from POSSUM score, 30, 60 and 90-day mortality and 30-day morbidity. POSSUM system's goodness-of-fit for predicting mortality and morbidity was assessed by Hosmer Lemeshow test (H-L T) and Standardized Mortality/Morbidity Ratio (SMR) and discriminative ability by the area under the ROC curves (ROC-AUC). Patients' average age was 70.8 years, 81% males. INTERVENTIONS: None. MAIN RESULTS: The overall 30-day mortality rate was 2.97% (n=6) and 30-day morbidity was 29.2% (n=59). POSSUM, P-POSSUM, V-POSSUM, V-POSSUM physiology and V-POSSUM Cambridge equation predicted an overall of 29.1, 4.43, 15.3, 21.9 and 13.5 deaths, respectively. POSSUM morbidity equation predicted 105.0 complications. H-LT p values were 0.001, 0.164, 0.208, 0.011, 0.331 and <0.001, respectively. SMRs and 95% confidence interval (CI) were 0.21[0.04-0.37], 1.35[0.27-2.44], 0.39[0.08 0.71], 0.27[0.06-0.49], 0.44[0.09-0.80] and 0.56[0.42-0.71], respectively. ROC AUC and 95% CI were 0.72[0.49-0.95], 0.72[0.49-0.95], 0.73[0.51-0.94], 0.69[0.50 0.89], 0.72[0.52-0.92] and 0.71[0.63-0.79], respectively. CONCLUSIONS: P-POSSUM had the best performance predicting 30-day mortality. All the other overestimated 30-day mortality. Prediction of morbidity was inadequate. POSSUM scoring models may not be robust tools for risk prediction in elderly patients undergoing major elective vascular surgery and need further calibration and discrimination. PMID- 29169797 TI - Carotid Artery Disease as a Predictor of In-Hospital Postoperative Stroke After Coronary Artery Bypass Grafting From 1999 to 2011. AB - BACKGROUND: In this study, the risk factors for stroke after coronary artery bypass grafting (CABG) were examined. In particular, the role of asymptomatic carotid artery stenosis (both unilateral and bilateral) as a predictor of in hospital postoperative stroke was investigated. Finally, the trends surrounding in-hospital postoperative stroke from 1999 to 2011 also were examined. The purpose of the study was to appropriately identify patients at high risk for stroke after CABG and spark discussion about the perioperative management of such patients. MATERIALS AND METHODS: Data from the Nationwide Inpatient Sample from 1999 to 2011 were analyzed retrospectively. The study cohort was identified using the International Classification of Diseases, Ninth Revision, Clinical Modification and Projection Clinical Classification Software codes. Exploratory statistics, univariate analyses, and multivariable regression were used for this study. RESULTS: The analysis demonstrated that both asymptomatic unilateral and bilateral carotid stenoses were independent risk factors for in-hospital postoperative stroke. In addition, increasing age, female sex, increasing van Walraven score, paralysis, neurologic disorders, history of infective endocarditis, asymptomatic basilar stenosis, and cerebral occlusion all were demonstrated to be statistically significant predictors of stroke. Patients with carotid stenosis and a van Walraven score >14 were found to be particularly vulnerable to in-hospital postoperative stroke. Lastly, predictors of carotid stenosis were examined, and increasing age, female sex, and increasing van Walraven score all were found to be significant predictors of asymptomatic carotid stenosis. CONCLUSIONS: This study examined risk factors for stroke after CABG in a large, longitudinal, and population-based database. The study found that both unilateral and bilateral asymptomatic carotid stenoses are indeed risk factors for in-hospital postoperative stroke. In addition, a number of other predictors were identified. These results can be used to identify patients at high risk for perioperative stroke and hopefully decrease the rate of a devastating complication of CABG. PMID- 29169798 TI - Cardioplegia During Minimally Invasive Mitral Valve Surgery, a Team Approach. PMID- 29169799 TI - Pharmacokinetics of Magnesium Bolus Therapy in Cardiothoracic Surgery. AB - OBJECTIVE: To investigate the pharmacokinetics of a 20 mmol magnesium bolus in regards to serum and urinary magnesium concentration, volume of distribution, and half-life. DESIGN: Prospective, experimental study. SETTING: A university affiliated teaching hospital. PARTICIPANTS: Twenty consecutive cardiac surgery patients treated with magnesium bolus therapy for prevention of arrhythmia. INTERVENTIONS: A 20-mmol bolus of magnesium sulfate was administered intravenously. MEASUREMENTS AND MAIN RESULTS: Median magnesium levels increased from 1.04 (interquartile range 0.94-1.23) mmol/L to 1.72 (1.57-2.14) mmol/L after 60 minutes of magnesium infusion (p < 0.001) but decreased to 1.27 (1.21-1.36) and 1.16 (1.11-1.21) mmol/L after 6 and 12 hours, respectively. Urinary magnesium concentration increased from 6.3 (4.2-14.5) mmol/L to 19.1 (7.4-34.5) mmol/L after 60 minutes (p < 0.001), followed by 22.7 (18.4-36.7) and 15 (8.4-19.7) mmol/L after 6 and 12 hours, respectively. Over the 12-hour observation period, the cumulative urinary magnesium excretion was 19.1 mmol (95.5% of the dose given). The median magnesium clearance was 10 (4.7-15.8) mL/min and increased to 14.9 (3.8-20.7; p = 0.934) mL/min at 60 minutes. The estimated volume of distribution was 0.31 (0.28-0.34) L/kg. CONCLUSION: Magnesium bolus therapy after cardiac surgery leads to a significant but short-lived increase of magnesium serum concentration due to renal excretion and distribution, and the magnesium balance is neutral after 12 hours. PMID- 29169800 TI - TGF-beta1/Smad2/3/Foxp3 signaling is required for chronic stress-induced immune suppression. AB - Depending on the duration and severity, psychological tension and physical stress can enhance or suppress the immune system in both humans and animals. Although it has been established that chronic stress exerts a significant suppressive effect on immune function, the mechanisms by which affects immune responses remain elusive. By employing an in vivo murine system, we revealed that TGF beta1/Smad2/3/Foxp3 axis was remarkably activated following chronic stress. Furthermore, TLR9 and p38 MAPK played a critical role in the activation of TGF beta1/Smad2/3/Foxp3 signaling cascade. Moreover, inhibition of TGF beta1/Smad2/3/Foxp3 or p38 significantly attenuated chronic stress-induced lymphocyte apoptosis and apoptosis-related proteins, as well as the differentiation of T regulatory cells in spleen. Interestingly, disequilibrium of pro-inflammatory and anti-inflammatory cytokines balance caused by chronic stress was also rescued by blocking TGF-beta1/Smad2/3/Foxp3 axis. These findings yield insight into a novel mechanism by which chronic stress modulates immune functions and identifies new targets for the development of novel anti-immune suppressant medications. PMID- 29169801 TI - Evaluating melanocytic lesions with single nucleotide polymorphism (SNP) chromosomal microarray. AB - Histopathology is the gold standard for diagnosing melanocytic lesions; however, distinguishing benign versus malignant is not always clear histologically. Single nucleotide polymorphism (SNP) microarray analysis may help in making a definitive diagnosis. Here, we share our experience with the Oncoscan FFPE Assay and demonstrate its diagnostic utility in the context of ambiguous melanocytic lesions. Eleven archival melanocytic lesions, including three benign nevi, four melanomas, three BAP1-deficient Spitzoid nevi and one nevoid melanoma were selected for validation. SNP-array was performed according to the manufacturer's protocol, using the recommended 80ng of DNA; however, as little as 15ng was used if the extraction yield was lower. Concordance was assessed with H&E and various combinations of BAP1 and p16 immunohistochemical stains (IHC) and external reference laboratory chromosomal microarray results. After validation, the SNP array was utilized to make definitive diagnoses in four challenging cases. Oncoscan SNP array findings were in concordance with H&E, IHC, and reference laboratory chromosomal microarray testing. The SNP-based microarray can accurately detect copy number changes and aid in making a more definitive diagnosis of challenging melanocytic lesions. This can be accomplished using significantly less DNA than is required by other microarray technologies. PMID- 29169802 TI - AKT activity is elevated in aggressive thyroid neoplasms where it promotes proliferation and invasion. AB - The PI3K/AKT/mTOR signaling pathway controls major cellular processes such as cell growth, proliferation and survival. Stimulation of this pathway leads to AKT phosphorylation and activation, resulting in phosphorylation of mTOR and myriad other targets. AKT upregulation has been implicated in thyroid cancer pathogenesis and is a candidate treatment target for patients with advanced disease that has not responded to traditional therapies. Here we evaluate a large series of benign and malignant thyroid tumors for AKT activity and intracellular distribution. We also deplete AKT from multiple thyroid cancer cell lines, including putative cancer stem cell lines, and measure the effect on proliferation and invasion in vitro. We show that active AKT has a predominantly nuclear distribution and its expression is highest in anaplastic thyroid carcinomas and papillary thyroid carcinomas, including encapsulated and invasive follicular variants. Depletion of AKT in thyroid carcinoma cell lines led to greatly reduced proliferative capacity and resulted in a reduction of invasive potential. A reduction in invasion was also observed in the cancer stem cell compartment. Targeting AKT activity in the clinical setting may slow the growth and spread of aggressive thyroid neoplasms, and target the tumor stem cell compartment. PMID- 29169803 TI - Expression, purification and characterization of two leucine aminopeptidases of the blood fluke, Schistosoma mansoni. AB - Schistosomiasis is a major neglected tropical disease (NTD) and considered the most important of the human helminthiases in terms of morbidity and mortality. Whereas treatment with praziquantel has been effective since the 1980s, the potential for the emergence of drug resistance has propelled the search for new interventions. Studies have revealed key roles of proteases in parasitic helminths during establishment of infection, tissue invasion, immune evasion, parasite feeding and development throughout the different developmental stages, pinpointing them as possible candidates. The leucine aminopeptidases (LAPs), members of the M17 family of Zn-metalloproteases, preferentially cleave leucine (Leu) residues at the N-terminal end of proteins and short peptides. These enzymes display broad proteolytic activities beyond Leu hydrolysis and are involved in processing, maturation, activation and/or degradation of substrates. As a vaccine immunogen, LAP induces protection against infection with the liver fluke Fasciola hepatica. Herein, two LAPs, SmLAP1 (Smp_030000) and SmLAP2 (Smp_083870) of the human blood fluke Schistosoma mansoni were cloned, expressed, purified and biochemically characterized. The enzymes differed in activity against diagnostic substrates, including leucine, methionine and arginine, with an optimal pH of 8.0. The activity increased in the presence of Mg+2 and Mn+2, and was inhibited by bestatin, a specific inhibitor of aminopeptidase. In addition, 1,10-phenanthroline and EDTA inhibited the enzymatic activity of SmLAP2. Finally, immunolocalization using antibodies specific for SmLAP1 and SmLAP2 identified the expression of these proteases in the egg and adult developmental stages of S. mansoni, and in intestinal epithelia, vitelline cells and sub-tegumental regions of the parasite. Characterization of schistosome proteases not only enhances understanding of the biology of schistosomes and schistosomiasis, but may also provide novel intervention approaches.

PMID- 29169810 TI - Evidence and experience with onabotulinumtoxinA in chronic migraine: Recommendations for daily clinical practice. AB - OnabotulinumtoxinA has been demonstrated to be effective as a preventive treatment in patients with chronic migraine (CM). Five years after the approval of onabotulinumtoxinA in Spain, the Headache Study Group of the Spanish Society of Neurology considered it worthwhile to gather a group of experts in treating patients with CM in order to draw up, based on current evidence and our own experience, a series of guidelines aimed at facilitating the use of the drug in daily clinical practice. For this purpose, we posed 12 questions that we ask ourselves as doctors, and which we are also asked by our patients. Each author responded to one question, and the document was then reviewed by everyone. We hope that this review will constitute a practical tool to help neurologists treating patients with CM. PMID- 29169811 TI - Evidence of and experience with the use of onabotulinumtoxinA in trigeminal neuralgia and primary headaches other than chronic migraine. AB - INTRODUCTION: In the field of headaches, onabotulinumtoxinA (onabotA) is well established as a treatment for chronic migraine (CM). In recent years, it has been used increasingly to treat other primary headaches (high-frequency episodic migraine, trigeminal-autonomic cephalalgias, nummular headache) and trigeminal neuralgia. As this treatment will progressively be incorporated in the management of these patients, we consider it necessary to reflect, with a fundamentally practical approach, on the possible indications of onabotA, beyond CM, as well as its administration protocol, which will differ according to the type of headache and/or neuralgia. DEVELOPMENT: This consensus document was drafted based on a thorough review and analysis of the existing literature and our own clinical experience. The aim of the document is to serve as guidelines for professionals administering onabotA treatment. The first part will address onabotA's mechanism of action, and reasons for its use in other types of headache, from a physiopathological and clinical perspective. In the second part, we will review the available evidence and studies published in recent years. We will add an "expert recommendation" based on our own clinical experience, showing the best patient profile for this treatment and the most adequate dose and administration protocol. CONCLUSION: Treatment with onabotA should always be individualised and considered in selected patients who have not responded to conventional therapy. PMID- 29169812 TI - Epilepsy in Africa: Past, present, and future. PMID- 29169814 TI - Safety of repeated sessions of transcranial direct current stimulation: A systematic review. AB - BACKGROUND: Repeated sessions of transcranial direct current stimulation (tDCS) are increasingly used for therapeutic applications. However, adverse events (AEs) associated with repeated sessions have not been comprehensively evaluated. OBJECTIVE: The aim of this study was therefore to evaluate the safety of repeated sessions of tDCS, examining AE risk relative to tDCS exposure. Further, to identify whether certain participant populations are particularly at risk from tDCS. METHODS: A systematic review and meta-analysis included sham-controlled studies (up to June 2017) involving two or more tDCS sessions, spaced not more than a day apart. Data was extracted on AEs reported, total tDCS exposure (cumulative charge), and diagnostic groups (Healthy, Pain Disorder, Stroke, Neurocognitive Disorder, Neuropsychiatric Disorder, and Other). Univariate simple linear meta-regression analyses examined AE likelihood, comparing active and sham tDCS, with increasing exposure. Rates of AEs were compared for diagnostic groups. RESULTS: 158 studies (total 4130 participants) met inclusion criteria and were included for quantitative analyses. The incidence of AEs (examined per session, by proportion of participants, and by the number of studies reporting AEs) did not increase with higher levels of tDCS exposure. Furthermore, AE rates were not found to be greater for any diagnostic group. CONCLUSIONS: Little evidence was found to suggest that repeated sessions of active tDCS pose increased risk to participants compared to sham tDCS within the limits of parameters used to date. Increased risks associated with greater levels of exposure to tDCS, or rare and under-reported AEs, however, cannot be ruled out. PMID- 29169813 TI - [Clinical problems in medical mycology: Problem number 51]. AB - A 48 year-old immunocompetent woman, who had a nodular lesion in the neck and a dense infiltrate at the lower lobe of the left lung, presented at the Mycology Unit of Muniz Hospital of Buenos Aires City. The pulmonary infiltrate disappeared spontaneously 3 months later. The histopathological study of the nodular lesion showed capsulated yeasts (mucicarmin and alcian blue positive stains) compatible with Cryptococcus. The mycological study of a new sample, obtained by a nodular puncture, allowed the isolation of yeasts, identified as Cryptococcus gattii (VGII). Latex test for Cryptococcus capsular antigen in serum was positive (1/100). CSF cultures rendered negative results. Fluconazole at a daily dose of 800mg was given during 45 days with partial improvement; as cultures from a new clinical sample were positive for Cryptococcus, the antimycotic was changed to itraconazole 400mg/day for 5 months, with an excellent clinical response. PMID- 29169817 TI - The French Infectious Diseases Society's readiness and response to epidemic or biological risk-the current situation following the Middle East respiratory syndrome coronavirus and Ebola virus disease alerts. AB - CONTEXT: In 2012, the French Infectious Diseases Society (French acronym SPILF) initiated the "Coordination of epidemic and biological risk" (SPILF-COREB - Emergences [SCE]) group to support the readiness and response of healthcare workers (HCWs) to new alerts. OBJECTIVE: To present the SCE group, its functioning, and the main support it provided for frontline HCWs. METHODS: A multidisciplinary group of heads of infectious disease departments from reference hospitals was created to build a network of clinical expertise for care, training, and research in the field of epidemic and biological risk (EBR). The network developed a set of standardized operational procedures (SOPs) to guide interventions to manage EBR-suspect patients. RESULTS: A working group created the SOP aimed at frontline HCWs taking care of patients. Priority was given to the development of a generic procedure, which was then adapted according to the current alert. Five key steps were identified and hierarchized: detecting, protecting, caring for, alerting, and referring the EBR patient. The interaction between clinicians and those responsible for the protection of the community was crucial. The SOPs validated by the SPILF and its affiliates were disseminated to a wide range of key stakeholders through various media including workshops and the SPILF's website. CONCLUSION: SPILF can easily adapt and timely mobilize the EBR expertise in case of an alert. The present work suggests that sharing and discussing this experience, initiated at the European level, can generate a new collective expertise and needs to be further developed and strengthened. PMID- 29169816 TI - Existing and investigational therapies for the treatment of Clostridium difficile infection: A focus on narrow spectrum, microbiota-sparing agents. AB - Despite intense international attention and efforts to reduce its incidence, Clostridium difficile infection (CDI) remains a significant concern for patients, clinicians, and healthcare organizations. It is costly for payers and disabling for patients. Furthermore, recurrent CDI is particularly difficult to manage, resulting in excess mortality, hospital length of stay, and other healthcare resource use. A greater understanding of the role of the gut microbiome has emphasized the importance of this diverse community in providing colonization resistance against CDI. The introduction of fidaxomicin, which has limited effect on the microflora has improved clinical outcomes in relation to disease recurrence. There are a number of other new agents in development, which appear to have a narrow spectrum of activity whilst exerting minimal effect on the microflora. Whilst the role of these emerging agents in the treatment of CDI is presently unclear, they appear to be promising candidates. PMID- 29169815 TI - Orchestration of epithelial-derived cytokines and innate immune cells in allergic airway inflammation. AB - Allergic asthma, a chronic respiratory disease, is a leading worldwide health problem, which inflames and constricts the airways, leading to breathing difficulty. Many studies have focused on the pathogenesis contributed by the adaptive immune system, including CD4+ T lymphocytes in delayed type hypersensitivity and B cell-produced IgE in anaphylaxis. More recently, a focus on the airway mucosal barrier and the innate immune system has highlighted, in coordination with T and B cells, to initiate and establish disease. This review highlights the impacts of epithelial-derived cytokines and innate immune cells on allergic airway reactions. PMID- 29169818 TI - Introduction of a Horizontal and Vertical Split Flow Model of Emergency Department Patients as a Response to Overcrowding. AB - INTRODUCTION: ED overcrowding is an issue that is affecting every emergency department and every hospital. The inability to maintain patient flow into and out of the emergency department paralyzes the ability to provide effective and timely patient care. Many solutions have been proposed on how to mitigate the effects of ED overcrowding. Solutions involve either hospital-wide initiatives or ED-based solutions. In this article, the authors seek to describe and provide metrics for a patient flow methodology that targets ESI 3 patients in a vertical flow model. METHODS: In the Stanford Emergency Department, a vertical flow model was created from existing ED space by removing fold-down horizontal stretchers and replacing them with multiple chairs that allowed for assessment and medical management in an upright sitting position. The model was launched and sustained through frequent interdisciplinary huddles, detailed inclusion and exclusion criteria, scripted text on how to promote the flow model to patients, and close analytics of metrics. Metrics for success included patient length of stay (LOS) for those triaged to the vertical flow area compared with ESI 3 patients triaged to the traditional emergency department as a comparison group. The secondary outcome is the total number of patients seen in the vertical flow area. This was a 6-month-September 2014, to February 2015-retrospective pre- and postintervention study that examined LOS as a marker for effective launch and implementation of a vertical patient workflow model. RESULTS: The patients triaged to the vertical flow area in the study period tended to be younger than in the control period (43 years versus 52 years, P = 0.00). There was a significant decrease in our primary end point: the total LOS for ESI 3 patients triaged to the vertical flow area (270 minutes versus 384 minutes, P = 0.00). CONCLUSION: Implementation of a vertical patient flow strategy can decrease LOS for the vertical ESI 3 patients based upon the inclusion and exclusion criteria. Furthermore, this is accomplished with minimal financial investment within the physical constraints of an existing emergency department.

PMID- 29169820 TI - Robotic and hybrid robotic transversus abdominis release may be performed with low length of stay and wound morbidity. AB - The objective of our study was to compare length of stay and wound complications after hybrid robotic transversus abdominis release (hrTAR) vs. robotic transversus abdominis release (rTAR) Two cohorts of patients undergoing robotic (rTAR) and hybrid robotic (hrTAR) performed by two surgeons at a single institution were analyzed. Mean length of stay (LOS) and incidence of surgical site occurrences (SSO) were compared. 57 patients undergoing rTAR and 25 patients undergoing hrTAR were analyzed. The hrTAR group had larger mean hernia dimensions and a larger proportion of men but otherwise the patient cohorts were similar. LOS was not statistically different between rTAR and hrTAR (2.8 vs 3.7 days p = 0.06). We found no difference in incidence of surgical site occurrences between the two groups (7.0% vs 4.0% p = 0.52). Hybrid robotic assisted TAR allows for repair of complex ventral hernias with similar lengths of stay and wound morbidity to pure robotic repairs. PMID- 29169821 TI - Faculty perceptions of resident skills decay during dedicated research fellowships. AB - BACKGROUND: Residents engaging in dedicated research experiences may return to clinical training with less surgical skill. The study aims were 1) to evaluate faculty perceptions of residents skills decay during dedicated research fellowships, and 2) to compare faculty and resident perceptions of residents skills decay. METHODS: Faculty and residents were surveyed on resident research practices and perceptions of resident skills decay. RESULTS: Faculty thought residents returning from research demonstrate less technical skill (Median = 4; 5 point Likert scale, 1 = Strongly disagree, 5 = Strongly agree), demonstrate less confidence (Median = 4), and require more instruction (Median = 4). Both faculty and residents perceived the largest skill reduction in complex procedures, technical surgical skills, and knowledge of procedure steps (p < 0.05). CONCLUSION: While dedicated research experiences provide valuable academic experience, there is a cost to clinical skills retention and confidence specifically in the areas of complex operative procedures and technical surgical skills. PMID- 29169822 TI - Faculty feedback versus residents' self-assessment of operative performance: Different but complementary. AB - BACKGROUND: Surgical training requires development of both technical and cognitive skills. The study analyzed feedback by faculty and residents' self assessments during a laparoscopic training course to identify structure of feedback in this context and compared the focus of trainees to faculty. METHODS: This study collected assessments by surgical residents and faculty during an intensive laparoscopic training course at a single institution. The residents' operative performance was assessed using validated assessment tools including free text feedback. Assessments were completed immediately following procedures. Feedback was analyzed using qualitative method. RESULTS: Eighty (80) residents participated. Three themes were identified: Assessment, instruction and occasion. Faculty provided significantly more feedback than trainees. Moreover, the content of feedback was different. Residents focused on technical performance, while faculty commented on technical and cognitive skills, efficiency and level of independence. Errors were mainly addressed by faculty. CONCLUSION: This study demonstrated differences in cognitive focus of trainees and faculty. Text feedback is informative in understanding perceived challenges. Faculty provided explicit assessment and instruction for improvement. The effectiveness of self assessment and feedback should be further studied. PMID- 29169823 TI - Effect of intra-operative single dose of dexamethasone for control of post operative nausea and vomiting on the control of glucose levels in diabetic patients. AB - BACKGROUND: Dexamethasone adds a unique challenge to glycemic control, and it may complicate patient care if there is an association between intra-operative dexamethasone and blood glucose levels. METHODS: We analyzed 396 diabetic patients who underwent general anesthesia for various surgical procedures and were hospitalized post-operatively for at least 24 h between January 2015 and June 2016. Patients were classified into two groups-those who received dexamethasone intra-operatively and those who did not. The groups were analyzed for blood glucose changes during and following their procedure. RESULTS: A total of 396 diabetic patients (152 (38.8%) dexamethasone group; 244 (62.2%) control) were included. The dexamethasone group had significantly lower preoperative blood glucose (135.5 mmol/L) compared to the control group (144.4 mmol/L) (p = 0.04) and significantly lower proportion of patients who had received insulin during surgery (14.9%) compared to the control group (23.4%) (p = 0.04). Overall, glucose levels declined from pre-op to post-op day 1 by 9.6 (62.9) (p = 0.007). CONCLUSION: Diabetic patients receiving dexamethasone for control of post operative nausea during surgery are at greater risk for increasing blood glucose levels and difficult glycemic control during and after surgery compared to patients receiving other medications to control post-operative nausea. PMID- 29169824 TI - Implementation of a flipped classroom approach to promote active learning in the third-year surgery clerkship. AB - BACKGROUND: Constructivist student-centered instructional models such as the flipped classroom (FC) have been shown to improve learning. METHODS: A FC approach was implemented for the surgery clerkship. Data was collected in phase 1 to evaluate student learning and attitudes. Based on these results, questions for the phase 2 open-ended survey were developed to improve understanding of learner attitudes, and ascertain how well the FC aligns with constructivist principles. RESULTS: There was no significant difference in shelf exam performance between the control and intervention groups. A majority of students agreed that they preferred the FC over lectures, and that their learning improved. Open-ended survey analysis demonstrated that the FC fostered self-directed, active learning, and that the in-class sessions facilitated application of concepts and deeper learning. Areas identified for improvement included better alignment with learning preferences through greater variety of pre-class learning options, improvement of podcast technical quality, and utilization of smaller in-class discussion groups. CONCLUSIONS: Students had a positive perception of the FC. The FC supports self-directed and more active and deeper in-class learning. PMID- 29169825 TI - Nitric oxide-cGMP-PKG signaling in the bed nucleus of the stria terminalis modulates the cardiovascular responses to stress in male rats. AB - The bed nucleus of the stria terminalis (BNST) constitutes an important component of neural substrates of physiological and behavioral responses to aversive stimuli, and it has been implicated on cardiovascular responses evoked by stress. Nevertheless, the local neurochemical mechanisms involved in BNST control of cardiovascular responses during aversive threats are still poorly understood. Thus, the aim of the present study was to assess the involvement of activation in the BNST of the neuronal isoform of the enzyme nitric oxide synthase (nNOS), as well as of signaling mechanisms related to nitric oxide effects such as soluble guanylate cyclase (sGC) and protein kinase G (PKG) on cardiovascular responses induced by an acute session of restraint stress in male rats. We observed that bilateral microinjection of either the nonselective NOS inhibitor Nomega-Nitro-L arginine methyl ester (L-NAME), the selective nNOS inhibitor Nomega-Propyl-L arginine (NPLA) or the sGC inhibitor 1H-[1,2,4]Oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) into the BNST enhanced the tachycardic response and decreased the drop in tail cutaneous temperature evoked by acute restraint stress, but without affecting the increase on blood pressure. Bilateral BNST treatment with the selective PKG inhibitor KT5823 also facilitated the heart rate increase and decreased the drop in cutaneous temperature, in addition to enhancing the blood pressure increase. Taken together, these results provide evidence that NO released from nNOS and activation of sGC and PKG within the BNST play an inhibitory influence on tachycardia to stress, whereas this signaling mechanism mediates the sympathetic-mediated cutaneous vasoconstriction.

PMID- 29169826 TI - Striatal structure and its association with N-Acetylaspartate and glutamate in autism spectrum disorder and obsessive compulsive disorder. AB - Autism spectrum disorders (ASD) and obsessive compulsive disorder (OCD) are often comorbid and are associated with changes in striatal volumes and N Acetylaspartate (NAA) and glutamate levels. Here, we investigated the relation between dorsal striatal volume and NAA and glutamate levels. We additionally compared striatal volume and shape between ASD, OCD and controls. T1-weighted magnetic resonance (MR) images, proton spectra (1H-MRS) in the left striatum, and phenotypic information were collected from 54 children with ASD, 32 with OCD, and 56 controls (aged 8-13 years) in a four-site study. Dorsal striatal volume and shape were determined using the FMRIB integrated registration and segmentation tool (FIRST). Spectra were processed with Linear Combination Model. The relationship of left striatal volume with NAA and glutamate was investigated, and group comparisons were performed for NAA levels and for bilateral striatal volume and shape. NAA levels were lower in subjects with ASD compared with controls (t=2.86, p=0.005) and were associated with striatal volume (beta=0.37, t=2.78, p=0.008). Glutamate levels were also associated with volume in the ASD group (beta=0.38, t=2.46, p=0.018). No group differences were found for striatal volume or shape, but a post-hoc diagnosis-by-hemisphere interaction (F(2,129)=3.86, p=0.024) revealed greater asymmetry (right>left) in striatal volume for the disorder-groups compared with controls. Our findings show involvement of NAA and glutamate in striatal volume in ASD and suggest greater asymmetry in paediatric ASD and OCD compared with controls, pointing to overlapping subcortical abnormalities. The lower NAA in ASD reflects reduced neuronal integrity or impaired neuronal functioning.

AB - Epstein-Barr virus (EBV), a human herpesvirus, is linked to both epithelial and lymphoid malignancies. Induction of EBV reactivation is a potential therapeutic strategy for EBV-associated tumors. In this study, we assessed the effects of rapamycin on EBV reactivation in gastric carcinoma cells. We found that rapamycin upregulated expression of EBV lytic proteins and increased the viral proliferation triggered by the EBV lytic inducer sodium butyrate. Reverse transcription-qPCR, luciferase activity assays, chromatin immunoprecipitation and western blotting were employed to explore the mechanism by which rapamycin promotes EBV reactivation. Our results showed that rapamycin treatment resulted in increased mRNA levels of EBV immediate-early genes. Rapamycin also enhanced the transcriptional activities of the EBV immediate-early lytic promoters Zp and Rp by strengthening Sp1 binding. Repression of the cellular ataxia telangiectasia mutated/p53 pathway by siRNA-mediated knockdown of the ataxia telangiectasia mutated gene significantly abrogated virus reactivation by rapamycin/sodium butyrate treatment, indicating that the ataxia telangiectasia-mutated/p53 pathway is involved in rapamycin-promoted EBV reactivation. Taken together, these findings demonstrate that rapamycin might have the potential to enhance the effectiveness of oncolytic viral therapies developed for EBV-associated malignancies.

AB - Insects are the host and vector of diverse viruses including those that infect vertebrates, plants, and fungi. Recent wide-scale transcriptomic analyses have uncovered the existence of a number of novel insect viruses belonging to an alphavirus-like superfamily (virgavirus/negevirus-related lineage). In this study, through an in silico search using publicly available insect transcriptomic data, we found numerous virus-like sequences related to insect virga/nege-like viruses. Phylogenetic analysis showed that these novel viruses and related virus like sequences fill the major phylogenetic gaps between insect and plant virga/negevirus lineages. Interestingly, one of the phylogenetic clades represents a unique insect-infecting virus group. Its members encode putative coat proteins which contained a conserved domain similar to that usually found in the coat protein of plant viruses in the family Virgaviridae. Furthermore, we discovered endogenous viral elements (EVEs) related to virga/nege-like viruses in the insect genomes, which enhances our understanding on their evolution. Database searches using the sequence of one member from this group revealed the presence of EVEs in a wide range of insect species, suggesting that there has been prevalent infection by this virus group since ancient times. Besides, we present detailed EVE integration profiles of this virus group in some species of the Bombus genus of bee families. A large variation in EVE patterns among Bombus species suggested that while some integration events occurred after the species divergence, others occurred before it. Our analyses support the view that insect and plant virga/nege-related viruses might share common virus origin(s). PMID- 29169831 TI - Next generation sequencing elucidates cacao badnavirus diversity and reveals the existence of more than ten viral species. AB - Cacao swollen shoot virus is a member of the family Caulimoviridae, genus Badnavirus and is naturally transmitted to Theobroma cacao (L.) by several mealybug species. CSSV populations in West African countries are highly variable and genetically structured into several different groups based on the diversity in the first part of ORF3 which encodes the movement protein. To unravel the extent of isolate diversity and address the problems of low titer and mixed viral sequences in samples, we used Illumina MiSeq and HiSeq technology. We were able to reconstruct de novo 20 new complete genomes from cacao samples collected in the Cocoa Research Institute of Ghana (CRIG) Museum and from the field samples collected in Cote d'Ivoire or Ghana. Based on the 20% threshold of nucleotide divergence in the reverse transcriptase/ribonuclease H (RT/RNase H) region which denotes species demarcation, we conclude there exist seven new species associated with the cacao swollen shoot disease. These new species along with the three already described leads to ten, the total number of the complex of viral species associated with the disease. A sample from Sri Lanka exhibiting similar leaf symptomology to West African CSSD-affected plants was also included in the study and the corresponding sequence represents the genome of a new virus named cacao bacilliform SriLanka virus (CBSLV). PMID- 29169833 TI - Molecular characterization of variants of a new 'rule-breaking' tobacco rattle virus RNA2 in potatoes. AB - In potato tubers showing pronounced corky ringspot symptoms, two related 'rule breaking" tobacco rattle virus (TRV) RNA2s, named Da-2 and Db-2, were identified. Their coat protein (cp) genes are preceded on the 5' side by an additional gene for a 35 kDa protein for which no relationships with previously described TRV genes or their expression products were found. With estimated 4296 and 4247 nucleotides (nts) the two RNAs are the longest TRV RNA2s described so far. The difference in size between Da-2 and Db-2 is due to a duplication of a stretch of 49 nts in the 5' untranslated region of Da-2. An alignment of TRV coat proteins (cp) revealed that up to about amino acid (aa) 176 they form two rather uniform groups. The much shorter C-terminal parts of the cps, however, differ considerably in size and composition. With 56 aa this C-terminal part is much longer in the Da and Db sequences than in all other TRV cps. It differs in 18 positions in the two strains whereas their N-terminal 184 aa differ only in two positions. - In young potato plants developing from bud-cuttings of TRV Db infected potato tubers which had been planted in soil free of virus and nematodes a gradual degradation of Db-2 was observed. In the newly formed rootlets already five days after planting a deletion of 80 nts was observed in the putative 2b gene which in other TRV strains encodes a protein necessary for nematode transmission. Thirty three days after planting the entire 2b gene, 119 nts at the 3'end of the cp gene and a portion of the original 3'untranslated region of Db-2 had been lost in the newly formed roots, leaves and stolons. The gene for the 35kDa protein was the only one which was not affected by deletions which seems to emphasize its importance for the virus. Fifty days after planting only TRV RNA1, but no TRV RNA2 were detectable. PMID- 29169834 TI - [An ovarian tumor can hide another one]. AB - We report the case of a 33-year-old woman who went under surgery for a cystic mature teratoma. The histological exam found two cysts, one was a mature teratoma and the other was a struma ovarii with a papillary carcinomatous element. Struma ovarii cancerization is seen in 5 to 10% of the cases usually under a papillary carcinoma type. Diagnosis is rarely made before surgery, the patients exceptionally show thyroid symptoms. Histologically, the tumour presents the same way as the one seen in the thyroid gland and BRAF mutations have been reported. The problem concerns ovarian metastases of a thyroid cancer. A normal thyroid check up and normal thyroid tissue close to the tumor in the ovary are in favor for a cancerize struma ovarii. The therapeutic care is not consensual, going from an annexectomy to hysterectomy and bilateral annexectomy. The patients must be followed on long-term with thyroglobulin quantitative analysis for at least 10 years and whole body scintigraphy with iodine 123 to detect relapse or metastases. The prognosis is usually good but precise criteria are still to define.

AB - We report the case of a large tumor in the left kidney with necrotic and hemorrhagic features in a 7-month-old child, which was clinically and radiologically suggestive of a nephroblastoma. The tumor was a nodular mass measuring 8cm in diameter occupying two thirds of the kidney and presenting areas of necrosis and hemorrhage. No capsular rupture or renal sinus infiltration were found. Adjacent renal parenchyma appeared mascroscopically normal. Histologically, the tumor showed a strictly tubulopapillary architectural pattern with numerous psammomas. The initial hypothesis was a purely epithelial nephroblastoma. However, this hypothesis was rejected due to some immunohistochemical and histological characteristics and the final diagnosis was a metanephric adenoma. Metanephric adenoma is an exceptionally rare benign renal tumor in children. However, pathologists need to keep it in mind because simple surgical excision is curative. PMID- 29169836 TI - [Classification of pancreatic neuroendocrine tumours: Changes made in the 2017 WHO classification of tumours of endocrine organs and perspectives for the future]. AB - The WHO classification of the tumors of endocrine organs, published in July 2017, has introduced significant changes in the classification of pancreatic neuroendocrine tumors, the previous version of which has appeared in 2010, within the WHO classification of the tumors of the digestive system. The main change is the introduction of a new category of well-differentiated neoplasms, neuroendocrine tumors G3, in addition to the previous categories of neuroendocrine tumors G1 and G2. The differential diagnosis between neuroendocrine tumors G3 (well-differentiated) and neuroendocrine carcinomas (poorly-differentiated) might be difficult; the authors of the WHO classification therefore suggest the use of a number of immunohistochemical markers to facilitate the distinction between the two entities. The other changes are: (a) the modification of the threshold between neuroendocrine tumors G1 and G2, now set at 3%; (b) the terminology used for mixed tumors: the previous term mixed adeno-neuroendocrine carcinoma (MANEC) is substituted by the term mixed neuroendocrine-non neuroendocrine neoplasm (MiNEN). Finally, the recommendations for Ki-67 index evaluation are actualized. Even if these changes only concern, stricto sensu, the neuroendocrine tumors of pancreatic location, they will probably be applied, de facto, for all digestive neuroendocrine tumors. The revision of the histological classification of pancreatic neuroendocrine tumors coincides with the revision of their UICC TNM staging; significant changes have been made in the criteria for T3 and T4 stages. Our professional practices have to take into account all these modifications. PMID- 29169837 TI - [Pseudo-cutaneous tumor in a renal transplant patient]. PMID- 29169838 TI - Mitigation of electroencephalographic and cardiovascular responses to castration in Bos indicus bulls following the administration of either lidocaine or meloxicam. AB - OBJECTIVE: To investigate the mitigating effects of administration of local anaesthetic or systemic meloxicam on the electroencephalographic (EEG) and cardiovascular responses during surgical castration of Bos indicus bull calves. STUDY DESIGN: Prospective, randomized, experimental study. ANIMALS: Thirty-six 6 8 month-old Bos indicus bull calves, with a mean +/- standard deviation weight of 237 +/- 19 kg. METHODS: Animals were allocated randomly to three groups of 12 (group L, 260 mg of 2% lidocaine subcutaneously and intratesticularly 5 minutes prior to castration; group M, 0.5 mg kg-1 of meloxicam subcutaneously 30 minutes prior to castration; group C, no preoperative analgesia administered). Anaesthesia was induced and maintained with halothane (0.9-1.1%) in oxygen. Electroencephalogram, heart rate (HR) and mean blood pressure (MAP) were recorded for 300 seconds prior to (baseline, B) and from the start of surgery (first testicle removal, T1). HR and MAP were compared at 10 second intervals for 90 seconds from the start of T1. Median frequency (F50), spectral edge frequency (F95) and total power of the EEG (Ptot) were analysed using area under the curve comparing T1 to B. RESULTS: All EEG variables were significantly different between B and T1 (p <= 0.0001). No differences in F50 were found between groups during T1 (p = 0.6491). F95 and Ptot were significantly different between group L and groups C and M during T1 (p = 0.0005 and 0.0163, respectively). There were transient significant changes in HR and MAP in groups L and M compared to group C during the 20-50 second periods. CONCLUSIONS: The EEG changes indicate nociceptive responses in all three groups during surgical castration, greater in group L compared to groups C and M. Both analgesics attenuated the peracute cardiovascular response. Lidocaine and meloxicam administered prior to castration attenuated these responses in Bos indicus bull calves. CLINICAL RELEVANCE: These findings provide support for the preoperative administration of lidocaine and potentially meloxicam for castration in Bos indicus bull calves. PMID- 29169839 TI - Cardiopulmonary effects of anaesthesia maintained by propofol infusion versus isoflurane inhalation in cheetahs (Acinonyx jubatus). AB - OBJECTIVE: To compare the cardiopulmonary effects of propofol total intravenous anaesthesia (TIVA) with isoflurane in cheetahs (Acinonyx jubatus) to evaluate feasibility for field use. STUDY DESIGN: Prospective clinical study. ANIMALS: A group of 24 adult cheetahs, 12 per group. METHODS: Cheetahs were immobilized with zolazepam/tiletamine (1.2 mg kg-1) and medetomidine [40 MUg kg-1, both intramuscular (IM)] by darting. A maintenance protocol of propofol TIVA (group P) or isoflurane inhalation (group I) was assigned randomly to each cheetah. Anaesthesia was maintained for at least 60 minutes. Cheetahs breathed spontaneously throughout; oxygen was supplemented at 3 L minute-1. Cardiopulmonary parameters were recorded at 5 minute intervals and three arterial blood gas samples were analysed. Following maintenance, atipamezole was administered IM (200 MUg kg-1) and recovery was observed. Data are reported as mean+/-standard deviation; variables over time were compared using a linear mixed model (fixed: time, treatment; random: cheetah). RESULTS: Lack of response to manipulations was maintained in all cases (end-tidal isoflurane percentage 1.1+/ 0.1%, propofol rate maintained at 0.1 mg kg-1 minute-1). The heart and respiratory rates were acceptable throughout maintenance. The end-tidal carbon dioxide tension increased slowly [44.0+/-5.0 mmHg (5.87+/-0.67 kPa)] with no differences between groups. All cheetahs were initially markedly hypertensive [mean arterial blood pressure (MAP): (163+/-17 mmHg)]. The MAP normalized for group I (125+/-30 mmHg) but remained high for group P (161+/-17 mmHg) (p < 0.001). Arterial carbon dioxide tension [48.9+/-14.6 mmHg (6.52+/-1.95 kPa)] never differed between groups. Initial arterial oxygen tension indicated borderline hypoxaemia, but improved with oxygen supplementation. Recovery time was 10.8+/-5.0 and 51.9+/-23.5 minutes for group I and group P, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: Both protocols provided acceptable cardiopulmonary values. Propofol may be an alternative to isoflurane for field use, but the prolonged recovery may make it less suitable for long-term anaesthesia. PMID- 29169840 TI - Cardiovascular effects, induction and recovery characteristics and alfaxalone dose assessment in alfaxalone versus alfaxalone-fentanyl total intravenous anaesthesia in dogs. AB - OBJECTIVE: To compare cardiovascular effects and anaesthetic quality of alfaxalone alone or in combination with a fentanyl constant rate infusion (CRI) when used for total intravenous anaesthesia (TIVA) in dogs. STUDY DESIGN: Prospective, blinded, randomized, experimental study. ANIMALS: A group of 12 intact female dogs. METHODS: Following intramuscular dexmedetomidine (10 MUg kg 1) and methadone (0.1 mg kg-1) administration, anaesthesia was induced intravenously with alfaxalone (2 mg kg-1) (group AP) or alfaxalone (2 mg kg-1) preceded by fentanyl (2 MUg kg-1) (group AF). Anaesthetic maintenance was obtained with an alfaxalone variable rate infusion (VRI) started at 0.15 mg kg-1 minute-1 (group AP) or an alfaxalone VRI (same starting rate) combined with a CRI of fentanyl (10 MUg kg-1 hour-1) (group AF). The alfaxalone VRI was adjusted every 5 minutes, based on clinical assessment. Cardiovascular parameters (recorded every 5 minutes) and recovery characteristics (using a numerical rating scale) were compared between groups. A mixed model statistical approach was used to compare the mean VRI alfaxalone dose and cardiovascular parameters between groups; recovery scores were analysed using the Wilcoxon rank-sum test (alpha = 0.05). RESULTS: The mean CRI alfaxalone dose for anaesthetic maintenance differed significantly between treatments [0.16 +/- 0.01 mg kg-1 minute-1 (group AP) versus 0.13 +/- 0.01 mg kg-1 minute-1 (group AF)]. Overall heart rate, systolic, mean and diastolic arterial pressures were lower in group AF than in group AP (p < 0.0001, p = 0.0058, p < 0.0001 and p < 0.0001, respectively. Recovery quality scores did not differ significantly and were poor in both groups. CONCLUSIONS AND CLINICAL RELEVANCE: In combination with a fentanyl CRI, an alfaxalone TIVA provides a cardiovascular stable anaesthesia in dogs. The addition of fentanyl results in a significant dose reduction. The quality of anaesthetic recovery remains poor. PMID- 29169841 TI - Distribution and neurochemistry of porcine urinary bladder-projecting sensory neurons in subdomains of the dorsal root ganglia: A quantitative analysis. AB - The aim of the present study has been to verify the inter- and intraganglionic distribution pattern of porcine urinary bladder-projecting (UBP) neurons localized in the sacral dorsal root ganglia (DRGs). The morphology and chemical phenotype of these cells have also been investigated. These neurons were visualized using the fluorescent tracer Fast Blue (FB) which was injected bilaterally into the urinary bladder wall of five juvenile female pigs. The intraganglionic distribution showed that small- and medium-sized FB+ perikarya were mainly located in the central (S3-S4) and periphero-central (S2) region of the ganglia, while large cells were heterogeneously distributed. Immunohistochemistry revealed that the most frequently observed markers in small and medium-sized UBP perikarya were: neurofilament 200, lectin from Bandeiraea simplicifolia (Griffonia simplicifolia) isolectin B4, substance P, calcitonin gene-related peptide, pituitary adenylate cyclase-activating polypeptide and transient receptor potential vanilloid 1. Moreover, UBP neurons containing these substances were also mainly observed in the central and periphero-central region of the ganglion. Differences in the percentage of traced cells and their neuropeptide content were observed between the S2, S3 and S4 DRGs. In conclusion, the present study, for the first time, describes the arrangement of UBP DRGs neurons within particular subdomains of sacral ganglia, taking into account their size and chemical phenotype. PMID- 29169842 TI - Anatomic characterization of the radial and ulnar nutrient arteries in humans. AB - BACKGROUND: The localization of nutrient foramens has been extensively studied in humans and other vertebrate animals. However, accurate information on the origin and extraosseous course of the nutrient arteries in some types of long tubular bones is lacking. Terminologia Anatomica, the international standard on human anatomic terminology, lists the radial nutrient artery (RNA) and the ulnar nutrient artery (UNA) as branches of the radial and ulnar arteries, respectively. Anatomy textbooks published in both German- and English-speaking countries regard both the RNA and UNA as branches of the anterior interosseous artery. METHODS: To clarify the anatomic characteristics of the RNA and UNA in humans, we reexamined the origin and course of these arteries by cadaveric dissection. RESULTS: Almost all RNAs and UNAs branched from the ulnar artery or its tributaries. In typical cases, the RNA branched from the anterior interosseous artery and the UNA branched from the proximal part of the ulnar artery or the anterior interosseous artery. These findings are reasonable from the perspective of regional anatomy, since the ulnar artery passes more deeply than the radial artery in the proximal forearm and thus the proximal part of the ulnar artery and its major branches are situated more closely to the radial and ulnar nutrient foramens. CONCLUSIONS: Based on our findings, it is necessary to correct the position of the RNA and UNA in the arterial hierarchy of T. Anatomica for accurate morphological description. PMID- 29169843 TI - Diagnostic evaluation of patients presenting with hematuria: An electronic health record-based study. AB - BACKGROUND: To gain new insights into the origin and prevention of diagnostic delays in the evaluation of hematuria in an electronic health record (EHR)-based integrated care setting. METHODS: We performed a retrospective review of 298 consecutive patients with new-onset hematuria at a Veterans Affairs facility from January 1, 2011 to December 31, 2013 excluding those where diagnostic evaluation was unnecessary (i.e., cystoscopy within 3 years prior). We collected data on presentation, such as red flags of painless gross hematuria (PGH) or asymptomatic microhematuria (AMH) and subsequent evaluation (imaging, urologic referral, and cystoscopy). Delay was defined when evaluation was not completed within 60 days. Logistic regression was performed to identify predictors of delay. RESULTS: Of 201 patients, 149 had delays. PGH was present in 99 patients. These patients had a higher rate of urology referral within 1 year than patients with AMH (86.7% vs. 64.7%; P<0.01) and were more likely to undergo cystoscopy (75.8% vs. 52%; P<0.01). Delays occurred in 67% of PGH patients vs. 81% of AMH patients (OR 0.46; P = 0.02), and roughly a third were related to scheduling/coordination, patient related issues, or delay in primary care referral. Bladder neoplasms were detected in 18% of patients with PGH and 2% of those with AMH. CONCLUSION: Delays in evaluation for hematuria occur commonly, regardless of strength of the red flag. Many delays were preventable and could be targeted with interventions including EHR-based tracking systems or reformed scheduling practices. PMID- 29169844 TI - Fertility preservation for men with testicular cancer: Is sperm cryopreservation cost effective in the era of assisted reproductive technology? AB - INTRODUCTION: Many patients do not cryopreserve sperm before undergoing cancer treatment because of high perceived costs of cryopreservation. We sought to investigate the cost-effectiveness of fertility preservation compared to posttherapeutic fertility treatment in testicular cancer patients. MATERIALS AND METHODS: We performed a systematic search of the PubMed database for the following: risk of azoospermia 12 months after surveillance, chemotherapy, retroperitoneal lymph node dissection, and radiation therapy (RT); rates of natural conception, and rates of conception with the use of intrauterine insemination or assisted reproductive technology, with or without microsurgical testicular sperm extraction (microTESE). A decision tree was constructed using the TreePlan add-in for Microsoft Excel (TreePlan Software, San Francisco, California). Cost-effectiveness was calculated as the overall cost of a given management branch, divided by likelihood of pregnancy. Calculations accounted for variable number of years of cryopreservation, and variable costs of microTESE. RESULTS: 1,113 articles were identified; 44 were included in the final analysis. Overall probability of pregnancy was higher among couples who cryopreserved sperm, versus those who did not. In patients undergoing active surveillance or retroperitoneal lymph node dissection, cryopreservation was more cost-effective if storage time was short (<6 years) or microTESE cost was high (>7,000). Cryopreservation prior to chemotherapy was more cost-effective unless microTESE cost was low (<7,000). Cryopreservation prior to RT was more cost-effective in almost all scenarios. CONCLUSIONS: Sperm cryopreservation prior to undergoing chemotherapy or RT remains the most cost-effective strategy for fertility preservation, across a range of possible costs associated with surgical sperm retrieval and in vitro fertilization/intracytoplasmic sperm injection. PMID- 29169845 TI - Impact of adequate pelvic lymph node dissection on overall survival after radical cystectomy: A stratified analysis by clinical stage and receipt of neoadjuvant chemotherapy. AB - PURPOSE: An adequate pelvic lymph node dissection (LND) during radical cystectomy (RC) for muscle-invasive bladder cancer (BCa) has been shown to provide a survival benefit. We designed a study to assess the effect of adequate LND on overall survival (OS) according to cT stage and receipt of neoadjuvant chemotherapy (NAC). MATERIAL AND METHODS: We identified 16,505 patients with localized BCa who received RC in the National Cancer Database (2004-2012). Inverse probability of treatment weighting (IPTW)-adjusted Kaplan-Meier and Cox regression analyses were used to compare OS between patients who received adequate LND (defined as >=10 nodes removed) and those who did not, stratified by cT stage and receipt of NAC. RESULTS: Overall 8,673 (52.55%) patients underwent adequate LND at RC for localized BCa. Median time to last follow-up was 55.49 months (IQR, 34.73-75.96 months). IPTW-adjusted Kaplan-Meier curves showed that median OS was improved in patients who received adequate LND (60.06 vs. 46.88 months). In patients who did not receive NAC, adequate LND was associated with an OS benefit for cT1/a/cis, cT2, and cT3/4 disease (P <= 0.008). Among patients who received NAC, adequate LND was not associated with any OS difference regardless of cT stage. CONCLUSION: Our data suggest that patients who did not receive NAC benefit from an adequate LND. However, the receipt of an adequate LND was not associated with an OS benefit in patients pretreated with NAC. Our study indicates that the receipt of NAC may eradicate micrometastatic disease, and thus limit the benefit of an adequate LND. PMID- 29169847 TI - Estimating the healthcare costs of treating prostate cancer in Australia: A Markov modelling analysis. AB - PURPOSE: To estimate the health system costs of prostate cancer by disease risk category and treatment type over 2016 to 2025 and to identify potential strategies to contain the cost increase. METHODS: A Markov cohort model was developed using clinical pathways from US prostate cancer guidelines and clinical expertise. Estimates of the probabilities of various treatments and outcomes and their unit costs were sourced from systematic reviews, meta-analyses, epidemiological publications and national cost reports. Estimated costs by stage of disease, by major treatments and by age at diagnosis were reported in 2016 US dollars. One-way and probabilistic sensitivity analyses assessed potential variation in the modeled costs. RESULTS: Australia-wide costs of prostate cancer were estimated at US$270.9 million in 2016 rising to US$384.3 million in 2025, an expected increase of 42%. Of this total increase, newly diagnosed low risk cases will contribute US$32.9 million, intermediate-risk US$56.8 million, high-risk US$53.3 million and advanced US$12.6 million. For men diagnosed at age 65 with low-risk disease, lifetime costs per patient were US$14,497 for surgery, US$19,665 for radiation therapies to the primary lesion, and US$9,234 for active surveillance. For intermediate- or high-risk disease, mean costs per patient were US$34,941 for surgery plus radiation and US$31,790 for androgen deprivation therapy plus radiation while advanced cancer therapies were at US$31,574 per patient. Additional costs for managing iatrogenic disease secondary to these treatments were excluded. CONCLUSION: Strategies for identifying patients early before cancers have spread are critical to contain the estimated 42% increase in costs over the next decade. Increased uptake of active surveillance would also lead to substantial cost-savings in the management of low-risk prostate cancer. PMID- 29169846 TI - PBRM1 and VHL expression correlate in human clear cell renal cell carcinoma with differential association with patient's overall survival. AB - OBJECTIVE: To identify the clinicopathological association of PBRM1 (Polybromo-1 gene) and VHL (von Hippel-Lindau gene) expression at mRNA and protein levels in clear cell renal cell carcinoma (ccRCC) and its role in tumor progression. PATIENTS AND METHODS: Immunohistochemical analysis, Western blotting and qPCR analysis of PBRM1 and VHL were performed on fresh-frozen ccRCC and adjacent normal tissue obtained from 70 patients who underwent radical nephrectomy. In addition, a tissue microarray (TMA) from specimens of 326 ccRCC patients was used to evaluate the effect of loss of PBRM1 and VHL immunohistological expression on clinicopathological features as well as patient survival. RESULTS: In frozen tissue, PBRM1 and VHL mRNA were significantly down-regulated in most ccRCC tumors (77.6%/80.6%). Simultaneous weak PBRM1 and VHL protein expression was observed in 21.4% of frozen tumors. In the TMA samples, weak PBRM1 and VHL immunohistochemical staining was observed in 60.4% of the cases and was correlated (P<0.001). The association of PBRM1 and VHL immunohistochemical expression with clinicopathological parameters depicts a variable picture: predominantly weak PBRM1 and VHL expression were significantly associated with higher Fuhrman grade (P = 0.012 and 0.024, respectively) but only weak VHL expression was associated with a higher pT stage (P = 0.023). PBRM1 expression did not affect the overall survival, whereas weak VHL expression was associated with decreased patient overall survival (P = 0.013). CONCLUSIONS: Our data suggest that reduced expression of PBRM1 and VHL is correlated with an increased tumor aggressiveness. Low VHL expression was identified as a risk factor for worse patient overall survival, independently from PBRM1 expression pattern. PMID- 29169848 TI - LC3-associated phagocytosis in microbial pathogenesis. AB - Phagocytosis is essential for uptake and elimination of pathogenic microorganisms. Autophagy is a highly conserved mechanism for incorporation of cellular constituents to replenish nutrients by degradation. Recently, parts of the autophagy machinery - above all microtubule-associated protein 1 light chain 3 (LC3) - were found to be specifically recruited to phagosomal membranes resulting in phagosome-lysosome fusion and efficient degradation of internalized cargo in a process termed LC3-associated phagocytosis (LAP). Many pathogenic bacterial, fungal and parasitic microorganisms reside within LAP-targeted single membrane phagosomes or vacuoles after infection of host cells. In this minireview we describe the state of knowledge on the interaction of pathogens with LAP or LAP-like pathways and report on various pathogens that have evolved strategies to circumvent degradation in LAP compartments. PMID- 29169850 TI - Family-based analysis of GGT1 and HNF1A gene polymorphisms in patients with polycystic ovary syndrome. AB - Polycystic ovary syndrome (PCOS) is a complex endocrine-metabolic disease. Previous studies indicate that genes GGT1 and HNF1A may contribute to the abnormal glucose metabolism and altered lipid profile that are important clinical features of PCOS. In the current study, the correlation between polymorphisms in the GGT1 and HNF1A genes and PCOS was explored. A total of 310 family trios were studied and the transmission disequilibrium test (TDT) was used to assess the linkage between PCOS and three single-nucleotide polymorphisms (SNP) (rs4820599 of GGT1, rs7305618 and rs2393791 of HNF1A). No deviations from HWE were detected. None of the three SNP markers showed significant transmission disequilibrium in PCOS family trios (rs4820599: GGT1 gene, chi2 = 1.067; rs7305618: HNF1A gene, chi2 = 0.013; rs2393791: HNF1A gene, chi2 = 0.031). In conclusion, no significant evidence supported a relationship between genes GGT1 and HNF1A and PCOS in the current family trios.

AB - Previously established individual differences in appetitive approach and devaluation sensitivity observed in goal- and sign-trackers may be attributed to differences in the acquisition, modification, or use of associative information in basolateral amygdala (BLA) pathways. Here, we sought to determine the extent to which communication of associative information between BLA and anterior portions of insular cortex (IC) supports ongoing Pavlovian conditioned approach behaviors in sign- and goal-tracking rats, in the absence of manipulations to outcome value. We hypothesized that the BLA mediates goal-, but not sign- tracking approach through interactions with the IC, a brain region involved in supporting flexible behavior. We first trained rats in Pavlovian lever autoshaping to determine their sign- or goal-tracking tendency. During alternating test sessions, we gave unilateral intracranial injections of vehicle or a cocktail of gamma-aminobutyric acid (GABA) receptor agonists, baclofen and muscimol, unilaterally into the BLA and contralaterally or ipsilaterally into the IC prior to reinforced lever autoshaping sessions. Consistent with our hypothesis we found that contralateral inactivation of BLA and IC increased the latency to approach the food cup and decreased the number of food cup contacts in goal trackers. While contralateral inactivation of BLA and IC did not affect the total number of lever contacts in sign-trackers, this manipulation increased the latency to approach the lever. Ipsilateral inactivation of BLA and IC did not impact approach behaviors in Pavlovian lever autoshaping. These findings, contrary to our hypothesis, suggest that communication between BLA and IC maintains a representation of initially learned appetitive associations that commonly support the initiation of Pavlovian conditioned approach behavior regardless of whether it is directed at the cue or the location of reward delivery.

AB - The aim of this study was to explore the pathogenic gene in a primary ovarian insufficiency (POI) patient from a consanguineous marriage family. The proband and her healthy mother were selected for whole-exome sequencing. By applying a strict filtering strategy, we found a novel homozygous missense mutation, c.G1070A (p.C357Y), of BMP15 in the proband, whereas her mother was heterozygous for this mutation. The mutation was highly conserved among species and predicted to be disorder causing. This study has revealed a novel homozygous mutation of the BMP15 gene that may be associated with POI.

PMID- 29169853 TI - Colony formation in solid medium by the relapsing fever spirochetes Borrelia hermsii and Borrelia turicatae. AB - Relapsing fever (RF) in North America is caused primarily by the spirochete Borrelia hermsii and is associated with the bite of its tick vector Ornithodoros hermsi. Although this spirochete was known long before the discovery of the Lyme disease (LD) spirochete, Borrelia burgdorferi, basic methods to facilitate the study of B. hermsii have lagged behind. One important technique to expedite the study of the molecular biology and pathogenesis of B. hermsii would be a reliable method to grow and clone these bacteria in solid medium, which we now describe. We have defined the solidifying agent, plating temperature, oxygen concentration, and pH for the efficient plating of two species of RF spirochetes, B. hermsii and Borrelia turicatae. Importantly, this technique allowed us to successfully isolate virulent, clonal cell lines of spirochetes, and to enumerate and isolate viable B. hermsii from infected mouse blood and tick tissues. Our results also demonstrate the value of testing a range of several environmental variables to increase the efficiency of bacterial isolation, which may be helpful for researchers working on other prokaryotes that are intractable for in vitro growth. PMID- 29169855 TI - Hypertensive complications of pregnancy: A clinical overview. AB - Hypertensive disorders in pregnancy are a worldwide health problem for women and their infants complicating up to 10% of pregnancies and associated with increased maternal and neonatal morbidity and mortality. In Europe, 2.3-3% of pregnancies are complicated by preeclampsia. Gestational diabetes, obesity, no previous or multiple births, maternal age less than 20 or greater than 35years old and thrombophilia can be some of the possible factors related to increased risk for hypertension in pregnancy. Complications of hypertension during pregnancy affect both mothers and their infants. Ambulatory blood pressure monitoring helps to distinguish true hypertension from the white coat as pregnant women with office abnormal values may have normal out of office blood pressure. Imbalance between proangiogenic and antiangiogenic factors in placenta may lead to endothelial dysfunction, vasoconstriction, activation of the coagulation system, and hemolysis. Carotid intima-media thickness, pulse wave velocity, augmentation index, and arterial wall tension were found to be significantly increased in women with preeclampsia compared to normotensive pregnant women. Uterine artery Doppler and serum biomarkers can be used to evaluate the probability of hypertension and complications during pregnancy, but further research in the field is needed. Lately, micro ribonucleic acids have also been the focus of research as potential biomarkers. PMID- 29169856 TI - Comparing the accuracy of medication order verification between pharmacists and a tech check tech model: A prospective randomised observational study. AB - BACKGROUND: Medication errors have the potential to cause significant harm and the final verification of dispensed medications is essential to patient safety. There is international evidence to demonstrate that trained pharmacy technicians can safely and accurately undertake the verification of medication orders in ward based unit dose containers. There is a need for evaluation of pharmacy technician verification of medication orders in broader contexts including the hospital inpatient dispensary. AIM: To compare the accuracy of Accuracy Checking Pharmacy Assistants (ACPTs) to pharmacists when verifying inpatient medication orders within the hospital pharmacy setting. METHOD: This 'real world' single-blinded study was conducted in the inpatient dispensary of a major tertiary hospital in Melbourne, Australia. Inpatient medication orders were randomly allocated to an ACPT or pharmacist for final verification, before being reviewed for accuracy by an independent research pharmacist blinded to study allocation. Errors identified by the reviewing pharmacist were documented and severity was assessed by an independent Medication Safety pharmacist. RESULTS: Between February and August 2014, three ACPTs verified 4718 items with 75 errors missed (1.59%), and twelve pharmacists verified 4194 items with 158 errors missed (3.77%). There was a statistically significant difference between both total and minor error rates, with pharmacists missing significantly more errors (total errors: p < 0.0001; minor errors: 1.42 vs 3.53%; p < 0.0001). There was no statistically significant difference in the rate of major errors missed by the two groups (0.17 vs 0.24%; p = 0.48). CONCLUSION: This study is the first of its kind in the hospital dispensary setting, demonstrating that the overall accuracy of ACPTs was greater than pharmacists for verifying dispensed medication orders. ACPTs missed fewer minor and overall errors than pharmacists, indicating that trained pharmacy technicians can verify medication orders safely and accurately. This study provides support for the tech-check-tech model in the hospital setting. PMID- 29169857 TI - Development and validation of new predictive equation for resting energy expenditure in adults with overweight and obesity. AB - BACKGROUND & AIMS: Accurate predictive equations of resting energy expenditure (REE) are crucial in devising nutritional strategies to manage overweight/obesity, especially in countries where these are highly prevalent. REE is the most common measurement used to estimate energy requirements in the nutritional context; the most accurate method of measuring REE is indirect calorimetry (IC). However, this method is costly and often rarely feasible in many clinical settings. The objective of the present study was to develop and validate a new equation for predicting REE in adults with overweight and obesity. METHODS: This was a cross-sectional study including 410 men and women with overweight and obesity (20-60 y). Participants were randomly assigned; the development group included 200 subjects and the validation group 210 subjects. The new predictive equation was derived using stepwise multiple linear regression analysis. The accuracy of the new equation was compared to several existing predictive equations (PEs). The accuracy rate was calculated as the percentage of subjects whose REE-PE was within +/-10% of the REE-IC. REE was measured by IC and anthropometric measurements. RESULTS: One predictive equation was developed (NEQ) in which weight was the strongest predictor of REE. Compared with others predicted equations already using, the new designed equation showed the less mean bias (Kj/day): NEQ: 25.7, Valencia:129, WHO/FAO/United Nations University: 270, Mifflin-St Jeor: 308, Owen: -808, Carrasco: -1097, Korth: -36.4, Johnstone: -375, Livingstone: -315, De Lorenzo: -28.3, Lazzer: -123, Muller: -145, Huang: -399 and Bernstein: -1335. CONCLUSIONS: The present equation had the highest predictive accuracy in subjects with overweight or obesity compared with the previous equations derived from different populations. Thus, these new equation can be used to assist the nutritional management of these subjects. PMID- 29169858 TI - Epicardial adipose tissue, alcohol consumption, and coronary artery disease severity. PMID- 29169859 TI - A model based on feature objects aided strategy to evaluate the methane generation from food waste by anaerobic digestion. AB - A model based on feature objects (FOs) aided strategy was used to evaluate the methane generation from food waste by anaerobic digestion. The kinetics of feature objects was tested by the modified Gompertz model and the first-order kinetic model, and the first-order kinetic hydrolysis constants were used to estimate the reaction rate of homemade and actual food waste. The results showed that the methane yields of four feature objects were significantly different. The anaerobic digestion of homemade food waste and actual food waste had various methane yields and kinetic constants due to the different contents of FOs in food waste. Combining the kinetic equations with the multiple linear regression equation could well express the methane yield of food waste, as the R2 of food waste was more than 0.9. The predictive methane yields of the two actual food waste were 528.22 mL g-1 TS and 545.29 mL g-1 TS with the model, while the experimental values were 527.47 mL g-1 TS and 522.1 mL g-1 TS, respectively. The relative error between the experimental cumulative methane yields and the predicted cumulative methane yields were both less than 5%.

AB - In the present work, the enhancement of biogas and methane yields through anaerobic co-digestion of the pre-hydrolised Organic Fraction of Municipal Solid Wastes (hOFMSW) and Maize Cob Wastes (MCW) in a lab-scale thermophilic anaerobic reactor was tested. In order to increase its biodegradability, MCW were submitted to an initial pre-treatment screening phase as follows: (i) microwave (MW) irradiation catalysed by NaOH, (ii) MW catalysed by glycerol in water and alkaline water solutions, (iii) MW catalysed by H2O2 with pH of 9.8 and (iv) chemical pre-treatment at room temperature catalysed by H2O2 with 4 h reaction time. The pre-treatments cataysed by H2O2 were performed with 2% MCW (wMCW/v alkaline water) at ratios of 0.125, 0.25, 0.5 and 1.0 (wH2O2/wMCW). The pre treatment that presented the most favourable balance between sugars, lignin, cellulose and hemicellulose solubilisations, as well as low production of phenolic compound and furfural (inhibitors), was the chemical pre-treatment catalysed by H2O2, at room temperature, with a ratio of 0.5 wH2O2/wMCW (Pre1). This Pre1 was then optimised testing reaction times of 1, 2 and 3 days at a different pH (11.5) and MCW percentage (10% w/v). The optimised pre-treatment that presented the best results, considering the same criteria defined above, was the one carried out during 3 days, at pH 9.8 and 10% MCW w/v (Pre2). The anaerobic reactor was initially fed with the hOFMSW obtained from the hydrolysis tank of an industrial AD plant. The hOFMSW was than co-digested with MCW submitted to the pre-treatment Pre1. In another assay, hOFMSW was co-digested with MCW submitted pre-treatment Pre 2. The co-digestion of hOFMSW + Pre1 increased the biogas yield by 38.9% and methane yield by 29.7%, when compared to the results obtained with hOFMSW alone. The co-digestion of hOFMSW + Pre2 increased biogas yield by 46.0% and CH4 yield by 36.3%. In both cases, the methane content obtained in the biogas streams was above 66% v/v. These results show that pre-treatment with H2O2, at room temperature, is a promising low cost way to valorize MCW through co-digestion with hOFMSW. PMID- 29169861 TI - Prevalence of restless legs syndrome during pregnancy: A systematic review and meta-analysis. AB - Pregnant women are more likely to be affected by restless legs syndrome (RLS) than the general population. Restless legs syndrome during pregnancy is associated with adverse maternal and fetal outcomes. Currently unknown is the worldwide and regional prevalence of RLS in pregnant women. We performed a meta analysis to provide a full profile of the prevalence of RLS during pregnancy. A systematic search of the PubMed, Medline, EMBASE, and Web of Science databases was performed to identify studies that were published up to April 2017, followed by random-effects meta-analyses. A total of 196 articles were identified, among which 27 longitudinal and cross-sectional observational studies with 51,717 pregnant subjects were included in the analysis. The pooled overall prevalence of RLS across all three trimesters was 21%. According to the regional classification of the World health organization, the prevalence of RLS during pregnancy in the European Region, Western Pacific Region, Eastern Mediterranean Region, and Region of the Americas was 22%, 14%, 30%, and 20%, respectively. The regional prevalence in the African Region and South-East Asia Region was not assessed because of insufficient data. We also analyzed the prevalence of RLS in the first, second, and third trimesters of pregnancy, and the rates of RLS were 8%, 16%, and 22%, respectively. We also found that the high prevalence of RLS decreased to 4% after delivery. No publication bias was found in these analyses. The findings emphasize the high occurrence of RLS during pregnancy. Future studies should examine the effects of RLS during pregnancy on maternal and fetal outcomes.

AB - OBJECTIVE: To provide dietitians with practical guidance on incorporating smartphone applications (apps) in the nutrition care process (NCP) to optimize patient education and counseling. METHODS: The current evidence-base for mobile health (mHealth) apps was searched using PubMed and Google Scholar. Where and how apps could be implemented by dietitians across the four steps of the NCP is discussed. RESULTS: With functionality to automatically convert patient dietary records into nutrient components, nutrition assessment can be streamlined using nutrition apps, allowing more time for dietitians to deliver education and nutrition counseling. Dietitians could prescribe apps to provide patients with education on nutrition skills and in counseling for better adherence to behavior change. Improved patient-provider communication is also made possible through the opportunity for real-time monitoring and evaluation of patient progress via apps. A practical framework termed the 'Mobile Nutrition Care Process Grid' provides dietitians with best-practice guidance on how to use apps. CONCLUSIONS: Including apps into dietetic practice could enhance the efficiency and quality of nutrition care and counseling delivered by dietitians. PRACTICE IMPLICATIONS: Apps should be considered an adjunct to enable dietetic counseling and care, rather than to replace the expertise, social support and accountability provided by dietitians.

AB - BACKGROUND AND OBJECTIVES: Despite the numerous investigations carried out in relation to melatonin, there is a lack of knowledge about the specific melatonin secretion patterns in the diverse primary sleep disturbances. The objective of this study was to analyze the plasma melatonin concentrations in children with primary sleep disorders and the effects of melatonin therapy on their serum levels and their actigraphic sleep parameters. METHODS: Fourteen participants (nine girls; seven to 14 years old) diagnosed with diverse primary sleep disorders were recruited. Four different melatonin secretion patterns were identified: low plasma melatonin levels, absence of a circadian rhythm, advanced acrophase, and delayed acrophase. A placebo (one week) was administered followed by three months of melatonin therapy (3 mg/night). Urinary 6-sulfatoxymelatonin levels, 24-hour plasma melatonin concentrations, and a seven-day actigraphic record were collected after both treatments. RESULTS: After melatonin therapy, a significant increase (P < 0.001) of urinary 6-sulfatoxymelatonin excretion with a clear circadian variation was observed. Plasma melatonin concentrations were also significantly higher with a recovery in the circadian rhythm. Actual sleep time was significantly longer, with a substantial reduction in the sleep onset latency and night awakenings. No severe side effects were reported. CONCLUSIONS: The main clinical implication of this study is to demonstrate the efficacy of melatonin in three main circumstances: an insufficient hormone production, a disturbed circadian rhythm, and an advanced or delayed acrophase. As ongoing work, we are exploring the effect of different doses of melatonin on the regulation of its concentrations and of its secretion rhythm. PMID- 29169868 TI - Response to Sharawat and Suther.

AB - Endoplasmic reticulum (ER) stress attributes a crucial role in diabetes-induced endothelial dysfunction. The present study investigated the effects of quercetin, a potent antioxidant on the attenuation of ER stress-modulated endothelial dysfunction in streptozotocin (STZ)-induced diabetic rats. Oral administration of quercetin for six weeks to diabetic rats dose-dependently reduced the blood glucose levels and improved insulin secretion. Histopathological examination of pancreatic tissues in diabetic rats showed pathological changes such as shrunken islets, reduction in islet area and distorted beta-cells, which were found to be restored by quercetin treatment. In addition, quercetin reduced the pancreatic ER stress-induced endothelial dysfunction as assessed by immunohistochemical analysis of C/ERB homologous protein (CHOP) and endothelin-1 (ET-1). Moreover, quercetin administration progressively increased the expression of vascular endothelial growth factor (VEGF) and its receptor, VEGFR2 in diabetes rats. Quercetin-mediated decrease in the nitric oxide (NO?) and cyclic 3',5'- guanosine monophosphate (cGMP) levels were also observed in the diabetic rats. Quercetin treatment reduced the lipid peroxidation in the diabetic rats, meanwhile increased the total antioxidant capacity in the pancreas from diabetic rats. Altogether, these results demonstrated the vasoprotective effect of quercetin against STZ-induced ER stress in the pancreas of diabetic rats. PMID- 29169873 TI - Modified HyperCVAD Versus Bortezomib-HyperCAD in Patients With Relapsed/Refractory Multiple Myeloma. AB - INTRODUCTION: Multiple myeloma (MM) is an incurable plasma cell malignancy, in which aggressive relapses might require salvage cytotoxic infusional chemotherapy. Several clinical trials that reported the efficacy of bortezomib led to institutional practice changes in which vincristine was replaced with bortezomib in the modified hyperCVAD regimen, creating a new treatment regimen, named "bortezomib-hyperCAD." PATIENTS AND METHODS: We retrospectively describe the effectiveness and tolerability of 2 chemotherapy regimens among 33 patients with relapsed and/or refractory MM. Patients who received >= 1 cycle of modified hyperCVAD or bortezomib-hyperCAD between 2011 and 2015 were assessed. RESULTS: The median number of cycles administered in each arm was 2. The overall response rate was 40% (6 partial responses) in the modified hyperCVAD group and 44.4% (1 complete response, 1 very good partial response, and 6 partial responses) in the bortezomib-hyperCAD group (Fisher exact P = .80). Median progression-free survival (PFS) and median overall survival (OS) for patients in the modified hyperCVAD group was 6.3 months and 11.1 months, respectively. This was comparable with patients in the bortezomib-hyperCAD group, who had a median PFS of 6.6 months and a median OS of 13.8 months (log rank P = .54 and .66, respectively). There was no statistically significant association between treatment arm and febrile neutropenia, emergency department visits, hospitalizations, or peripheral neuropathy (all Fisher exact P values > .05). CONCLUSION: Overall effectiveness and tolerability outcomes were similar between modified hyperCVAD and bortezomib hyperCAD, with both regimens showing an impressive response rate among refractory and heavily pretreated patients with relapsed MM. PMID- 29169874 TI - Intellectual disability in children and teenagers: Influence on family and family health. Systematic review. AB - OBJECTIVE: To examine the influence of a child or adolescent with intellectual disabilities on the family unit. METHOD: A systematic review of the literature, following the recommendations of the PRISMA statement, was carried out on the PubMed, Scopus, CINAHL, PsycINFO and Psicodoc databases. Original articles were found, published in the last 5 years, in Spanish, English, Portuguese, Italian or French, with summary and full text and satisfactory or good methodological quality. Two independent researchers agreed on their decisions. RESULTS: In general, care is provided in the family, mothers assume the greater responsibility, and their wellbeing is lower than that of fathers. Having the support of the husband improves their quality of life. The fraternal subsystem can be affected, with regard to the warmth and the status/power of the relationship, and behavioural problems. Family health may be affected in all its dimensions: family functioning and atmosphere due to increased demands and changes in the organisation and distribution of roles; family resilience and family coping, due to rising costs and dwindling resources; family integrity could be strengthened by strengthened family ties. Quality of family life is enhanced by emotional support. CONCLUSIONS: These families may need individualised attention due to the increased demand for care, diminishing resources or other family health problems. Nurses using a family-centred care approach can identify these families and help them to normalise their situation by promoting their family health and the well-being of its members.

However, prenatal modulation of lung development remains experimental. Fetoscopic endoluminal tracheal occlusion triggers lung growth and is currently being evaluated in a global clinical trial. Prenatal transplacental sildenafil administration may in due course be a therapeutic approach, reducing the occurrence of persistent pulmonary hypertension, either alone or in combination with fetal surgery.

AB - OBJECTIVE: The objective of this study was to demonstrate the 3-year outcome of the covered endovascular reconstruction of the aortic bifurcation (CERAB) technique for the treatment of extensive aortoiliac occlusive disease (AIOD). METHODS: Between February 2009 and July 2016, all patients treated with the CERAB technique for AIOD were identified in the local databases of two centers and analyzed. Demographics and lesion characteristics were scored. Follow-up consisted of clinical assessment, duplex ultrasound, and ankle-brachial indices. Patency rates and clinically driven target lesion revascularization were calculated by Kaplan-Meier analysis. RESULTS: Of 130 patients (69 male and 61 female) treated, 68% were diagnosed with intermittent claudication and 32% suffered from critical limb ischemia. The majority (89%) were TransAtlantic Inter Society Consensus II D lesions, and the remaining were B and C lesions (both 5%). Median follow-up was 24 months (range, 0-67 months). The technical success rate was 97%, and 67% of cases were performed completely percutaneously. The ankle brachial index improved significantly from 0.65 +/- 0.22 preoperatively to 0.88 +/- 0.15 after the procedure. The 30-day minor and major complication rate was 33% and 7%. The median hospital stay was 2 days (range, 1-76 days). At 1 year and 3 years of follow-up, 94% and 96% of the patients clinically improved at least one Rutherford category (2% and 0% unchanged, 4% and 4% worsened). Limb salvage rate was 98% at 1 year and 97% at 3 years of follow-up. Primary, primary assisted, and secondary patency was 86%, 91%, and 97% at 1 year; 84%, 89%, and 97% at 2 years; and 82%, 87%, and 97% at 3 years. Freedom from clinically driven target lesion revascularization was 87% at 1-year follow-up and 86% at both 2 year and 3-year follow-up. CONCLUSIONS: The CERAB technique is a safe and feasible technique for the treatment of extensive AIOD with good 3-year results regarding patency and clinical improvement. PMID- 29169877 TI - Cetuximab plus carboplatin and paclitaxel with or without bevacizumab versus carboplatin and paclitaxel with or without bevacizumab in advanced NSCLC (SWOG S0819): a randomised, phase 3 study. AB - BACKGROUND: EGFR antibodies have shown promise in patients with advanced non small-cell lung cancer (NSCLC), particularly with squamous cell histology. We hypothesised that EGFR copy number by fluorescence in-situ hybridisation (FISH) can identify patients most likely to benefit from these drugs combined with chemotherapy and we aimed to explore the activity of cetuximab with chemotherapy in patients with advanced NSCLC who are EGFR FISH-positive. METHODS: We did this open-label, phase 3 study (SWOG S0819) at 277 sites in the USA and Mexico. We randomly assigned (1:1) eligible patients with treatment-naive stage IV NSCLC to receive paclitaxel (200 mg/m2; every 21 days) plus carboplatin (area under the curve of 6 by modified Calvert formula; every 21 days) or carboplatin plus paclitaxel and bevacizumab (15 mg/kg; every 21 days), either with cetuximab (250 mg/m2 weekly after loading dose; cetuximab group) or without (control group), stratified by bevacizumab treatment, smoking status, and M-substage using a dynamic-balancing algorithm. Co-primary endpoints were progression-free survival in patients with EGFR FISH-positive cancer and overall survival in the entire study population. We analysed clinical outcomes with the intention-to-treat principle and analysis of safety outcomes included patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov (number NCT00946712). FINDINGS: Between Aug 13, 2009, and May 30, 2014, we randomly assigned 1313 patients to the control group (n=657; 277 with bevacizumab and 380 without bevacizumab in the intention-to-treat population) or the cetuximab group (n=656; 283 with bevacizumab and 373 without bevacizumab in the intention-to treat population). EGFR FISH was assessable in 976 patients and 400 patients (41%) were EGFR FISH-positive. The median follow-up for patients last known to be alive was 35.2 months (IQR 22.9-39.9). After 194 progression-free survival events in the cetuximab group and 198 in the control group in the EGFR FISH-positive subpopulation, progression-free survival did not differ between treatment groups (hazard ratio [HR] 0.92, 95% CI 0.75-1.12; p=0.40; median 5.4 months [95% CI 4.5 5.7] vs 4.8 months [3.9-5.5]). After 570 deaths in the cetuximab group and 593 in the control group, overall survival did not differ between the treatment groups in the entire study population (HR 0.93, 95% CI 0.83-1.04; p=0.22; median 10.9 months [95% CI 9.5-12.0] vs 9.2 months [8.7-10.3]). In the prespecified analysis of EGFR FISH-positive subpopulation with squamous cell histology, overall survival was significantly longer in the cetuximab group than in the control group (HR 0.58, 95% CI 0.36-0.86; p=0.0071), although progression-free survival did not differ between treatment groups in this subgroup (0.68, 0.46-1.01; p=0.055). Overall survival and progression-free survival did not differ among patients who were EGFR FISH non-positive with squamous cell histology (HR 1.04, 95% CI 0.78-1.40; p=0.77; and 1.02, 0.77-1.36; p=0.88 respectively) or patients with non-squamous histology regardless of EGFR FISH status (for EGFR FISH positive 0.88, 0.68-1.14; p=0.34; and 0.99, 0.78-1.27; p=0.96; respectively; and for EGFR FISH non-positive 1.00, 0.85-1.17; p=0.97; and 1.03, 0.88-1.20; p=0.69; respectively). The most common grade 3-4 adverse events were decreased neutrophil count (210 [37%] in the cetuximab group vs 158 [25%] in the control group), decreased leucocyte count (103 [16%] vs 74 [20%]), fatigue (81 [13%] vs 74 [20%]), and acne or rash (52 [8%] vs one [<1%]). 59 (9%) patients in the cetuximab group and 31 (5%) patients in the control group had severe adverse events. Deaths related to treatment occurred in 32 (6%) patients in the cetuximab group and 13 (2%) patients in the control group. INTERPRETATION: Although this study did not meet its primary endpoints, prespecified subgroup analyses of patients with EGFR FISH-positive squamous-cell carcinoma cancers are encouraging and support continued evaluation of anti-EGFR antibodies in this subpopulation.

PMID- 29169880 TI - Evaluating the Benefit of Elevated Acoustic Output in Harmonic Motion Estimation in Ultrasonic Shear Wave Elasticity Imaging. AB - Harmonic imaging techniques have been applied in ultrasonic elasticity imaging to obtain higher-quality tissue motion tracking data. However, harmonic tracking can be signal-to-noise ratio and penetration depth limited during clinical imaging, resulting in decreased yield of successful shear wave speed measurements. A logical approach is to increase the source pressure, but the in situ pressures used in diagnostic ultrasound have been subject to a de facto upper limit based on the Food and Drug Administration guideline for the mechanical index (MI <1.9). A recent American Institute of Ultrasound in Medicine report concluded that an in situ MI up to 4.0 could be warranted without concern for increased risk of cavitation in non-fetal tissues without gas bodies if there were a concurrent clinical benefit. This work evaluates the impact of using an elevated MI in harmonic motion tracking for hepatic shear wave elasticity imaging. The studies indicate that high-MI harmonic tracking increased shear wave speed estimation yield by 27% at a focal depth of 5 cm, with larger yield increase in more difficult-to-image patients. High-MI tracking improved harmonic tracking data quality by increasing the signal-to-noise ratio and decreasing jitter in the tissue motion data. We conclude that there is clinical benefit to use of elevated acoustic output in shear wave tracking, particularly in difficult-to-image patients.

AB - OBJECTIVE: Family caregiver involvement may improve patient and family outcomes in the intensive care unit. This study describes critical care nurses' approaches to involving family caregivers in direct patient care. RESEARCH METHODOLOGY & DESIGN: This is a qualitative content analysis of text captured through an electronic survey. SETTING: A convenience sample of 374 critical care nurses in the United States who were subscribers to one of the American Association of Critical Care Nurses social media sites or electronic newsletters. MAIN OUTCOME MEASURE: Critical care nurses' responses to five open-ended questions about their approaches to family involvement in direct patient care. FINDINGS: Nurse, patient and family caregiver factors intersected in the context of the professional practice environment and the available resources for family care. Two main themes were identified: "Involving family caregivers in patient care in the intensive care unit requires careful ssessment" and "There are barriers and facilitators to caregiver involvement in patient care in the intensive care unit." CONCLUSION: Patient care demands, the professional practice environment and a lack of resources for families hindered nursing family caregiver involvement. Greater attention to these barriers as they relate to family caregiver involvement and clinical outcomes should be a priority in future research.

AB - PURPOSE: To evaluate the reproducibility of parafoveal microvascular anatomy of 7 different optical coherence tomography angiography (OCT-A) devices by comparing vessel density (VD), fractal dimension (FD), and foveal avascular zone (FAZ) of superficial and deep capillary plexus in healthy volunteers. DESIGN: Reliability analysis. METHODS: Consecutive healthy volunteers presenting at the Eye Clinic, Department of Biomedical and Clinical Sciences, Luigi Sacco Hospital, University of Milan in the same clinic visit were imaged by 7 different OCT-A devices: Optovue RTVue XR Avanti (Optovue, Inc, Fremont, California, USA), prototype Spectralis OCT-A (Spectralis; Heidelberg Engineering, Heidelberg, Germany), AngioPlex (Cirrus 5000 HD-OCT; Carl Zeiss Meditec, Inc, Dublin, California, USA), prototype PlexElite (Carl Zeiss Meditec), RS-3000 Advance (Nidek, Gamagori, Japan), OCT-HS100 (Canon, Tokyo, Japan), and Revo NX (Optopol Technology SA, Zawiercie, Poland). OCT-A examinations were performed using a 3 * 3 mm volume scan pattern centered on the fovea. Mean VD, FD, and FAZ values between the instruments were compared. RESULTS: The 7 different devices presented measurements with different mean values, with only a limited number of comparisons not significantly different between the instruments. Moreover, Bland Altman analysis revealed that the limits of agreement for all the comparisons were not acceptable. Regression analysis was used in the development of tables to compare various devices, despite which large standard errors were found for both intercepts and slope conversion values. CONCLUSIONS: Our results suggest that the comparison between instruments is nearly impossible and the set of measurements from the various instruments are not interchangeable regarding VD, FD, and FAZ for both the superficial and deep capillary plexus.

AB - The "Spiked Helmet" sign (SHs), is a recently described electrocardiographic sign which is associated with critical illness and with very high risk of impending death. Here, we report the SHs in patient with sepsis and a possible diagnosis of Takotsubo cardiomyopathy (TC). PMID- 29169885 TI - Model performance and variable selection method - A reply to the reader. PMID- 29169886 TI - A potential diagnostic pitfall in acute chest pain: Massive pulmonary embolism mimicking acute STEMI. AB - BACKGROUND: Pulmonary embolism (PE) represents a clinical challenge for clinicians because of nonspecific presentations, including dyspnea, chest pain, and tachycardia. The immediate 12-lead electrocardiogram (ECG) is commonly used to facilitate differential diagnosis of acute chest pain. Although relative rare, massive pulmonary embolism could induce ST segment elevation and mimic acute myocardial infarction. CASE PRESENTATION: We present a challenging scenario that ECG showed ST segment elevation, nevertheless, urgent coronary angiogram revealed non-obstructive coronary artery disease. Unfortunately, the patient suffered from cardiac arrest and required extracorporeal membrane oxygenation devices. Finally, massive pulmonary embolism was diagnosed. CONCLUSION: This case illustrates acute PE could mimic ST segment elevation myocardial infarction. ST elevations on ECG should be interpreted after considering clinical presentations before making a decision.

PMID- 29169888 TI - Prevalence and treatment of anxiety among emergency department patients with pain. PMID- 29169889 TI - Transitory effusive-constrictive pericarditis. AB - Pericardial effusion of various sizes is a quite common clinical finding, while its progression to effusive-constrictive pericarditis occurs in about 1.4-14% of cases. Although available evidence on prevalence and prognosis of this rare pericardial syndrome is poor, apparently a considerable proportion of patients conservatively managed has a spontaneous resolution after several weeks. A 61 year-old female presented to our emergency department reporting fatigue, effort dyspnea and abdominal swelling. The echocardiography showed large pericardial effusion with initial hemodynamic impact, so she underwent a pericardiocentesis with drainage of 800-850cm3 of exudative fluid, on which diagnostic investigations were undertaken: possible viral and bacterial infections, medical conditions, iatrogenic causes, neoplastic and connective tissue diseases were all excluded. Despite empirical therapy with NSAIDs and colchicine, after about one week she had a recurrence of pericardial effusion and progressive development of constriction. Echocardiography performed after a few weeks of anti-inflammatory therapy showed resolution of constriction and PE, with clinical improvement. If progression of pericardial syndromes to a constrictive form is rarely described in literature, cases of transitory effusive-constrictive phase are even more uncommon, mainly reported during the evolution of pericardial effusion. According to the available data, risk of progression to a constrictive form is very low in case of idiopathic pericardial effusion. We report a case of large idiopathic subacute pericardial effusion, treated with pericardiocentesis and then evolved into an effusive-constrictive pericarditis. A prolonged anti-inflammatory treatment leads to complete resolution of pericardial syndrome without necessity of pericardiectomy. PMID- 29169891 TI - Construction of a novel vaccine by conjugating a B-cell epitope of DPP4 to peptide IA2(5)-P2-1 to significantly control type 1 diabetes in NOD mice. AB - Type 1 diabetes is a chronic organ-specific autoimmune disease in which selective destruction of insulin-producing beta cells leads to impaired glucose metabolism and its attendant complications. IA2(5)P2-1, a potent immunogenic carrier which designed by our laboratory, can induce high titer specific antibodies when carry a B cell epitope, such as B cell epitopes of DPP4, xanthine oxidase, and Urate transporter protein. In this report, we describe a novel multi-epitope vaccine composing a peptide of DPP4, an anti-diabetic B epitope of Insulinoma antigen 2(IA-2) and a Th2 epitope (P2:IPALDSLTPANED) of P277 peptide in human heat shock protein 60 (HSP60). Immunization with the multi-epitope vaccine in non-obese diabetic (NOD) mice successfully induced specific anti-DPP4 antibody, inhibited plasma DPP4 activity, and increased serum GLP-1 level. Moreover, this antibody titer was correlated with the dose of immunization (20MUg, 100MUg). Inoculation of this vaccine in NOD mice significantly control blood glucose level, improved glucose excursion and increased insulin level in vivo. Consistent with a lower diabetic and insulitis incidence, a induced splenic T cells proliferation and tolerance were observed. IFN-gamma secretion reduced and IL-10 increased significantly in the D41-IA2(5)-P2-1 treated mice compared to P277 and control group due to the potential immunomodulatory effect of the epitope in the vaccine. Immunohistochemical analysis and cytometry showed a rebalance of Th1/Th2 in NOD mice. Our results demonstrate that this multi-epitope vaccine may serve as a promising therapeutic approach for type 1 diabetes. PMID- 29169890 TI - Differences between vaccinated and unvaccinated women explain increase in non vaccine-type human papillomavirus in unvaccinated women after vaccine introduction. AB - The aim of this study was to determine whether an observed increase in non vaccine-type human papillomavirus (HPV) in unvaccinated women during the first eight years after vaccine introduction may be explained by differences in demographics or sexual behaviors, instead of type replacement. We analyzed data from three cross-sectional surveillance studies of 13-26 year-old women (total N = 1180). For women recruited from a health department clinic, older age (OR = 1.4, 95% CI: 1.2-1.6) and consistent condom use with main partner in the past 3 months (OR = 11.6, 95% CI: 3.4-40) were associated with being unvaccinated. For women recruited from a teen health center African American race (OR = 0.2, 95% CI: 0.07-0.7) and having Medicaid health insurance (OR = 0.3, 95% CI: 0.1-0.7) were inversely associated with being unvaccinated. The observed increase in non vaccine-type HPV prevalence in unvaccinated women may be explained by differences between unvaccinated and vaccinated women. PMID- 29169892 TI - Immunization effects of a communication intervention to promote preteen HPV vaccination in primary care practices. AB - OBJECTIVES: HPV vaccination at the recommended ages of 11-12 is highly effective yet has stalled well below the goal of 80% of the population. We evaluated a statewide practice-based communication intervention (tools: brochures, posters, online training for providers and resources for parents, video game for preteens) to persuade parents, preteens and providers to vaccinate against HPV. The 9-month intervention started May 1, 2015. METHODS: We compared vaccine initiation and completion rates over three 9-month periods (baseline, intervention, post intervention) between practices enrolled in the intervention and a comparable comparison group. All practices reported to the North Carolina Immunization Registry (NCIR) and had at least 100 11- and 12-year-olds who had not completed the HPV vaccine series. Of 175 eligible practices, the 14 intervention practices included 19,398 individuals and the 161 comparison practices included 127,896 individuals. An extended Cox model was used to test the intervention effect. RESULTS: The intervention had a significant effect on both initiation and completion during the intervention and post-intervention periods; the estimated hazard ratio (HR) for initiation was 1.17 (p = .004) during the intervention and 1.11 (p = .005) post-intervention. Likewise, completion during the intervention period was 17% higher in intervention practices, after controlling for baseline differences. This effect increased in the post-intervention period to 30% higher (p = .03). CONCLUSIONS: Individuals in the intervention practices were 17% more likely to initiate and complete HPV vaccination than in the comparison practices during the intervention period and the effect was sustained post-intervention. This intervention is promising for increasing rates of HPV vaccination at ages 11 12. PMID- 29169894 TI - Preparing for rotavirus vaccine introduction - A retrospective assessment of the epidemiology of intussusception in children below 2 years of age in Nepal. AB - BACKGROUND: Rotavirus is the most common cause of severe diarrhea in Nepali children, accounting for 25-33% of childhood diarrhea hospitalizations. Two rotavirus vaccines recommended for inclusion in national immunization programs have been associated with a low risk of intussusception in post-marketing studies conducted in several countries. Data on the epidemiology of intussusception hospitalizations are lacking in Nepal. Thus, we aimed to describe the epidemiology of intussusception-associated hospitalizations among Nepali children in preparation for rotavirus vaccine introduction. METHODS: A retrospective review of intussusception hospitalizations for a three year period was conducted at two major pediatric hospitals in Kathmandu, Nepal. Possible intussusception cases were identified through admission, discharge, and operation theater logs and ultrasound registers. Cases with a diagnosis of possible intussusception were selected for medical record review and classified as confirmed if they met the Brighton Collaboration level 1 criteria of diagnostic certainty and the child was aged < 24 months. Data on demographics, clinical course, and outcome were abstracted and analyzed. RESULTS: Eight-five confirmed intussusception cases were identified; most (96%) were confirmed at surgery. The number of intussusception cases peaked between ages 4-7 months; no cases occurred in children 0-2 months. Fifty-nine (64%) case-patients were male. The median duration of symptoms before admission was 2 days (range: 0-14). Abdominal pain, bloody stool, and vomiting were the most common clinical features. All cases underwent surgical treatment; there was only one death. CONCLUSIONS: This is the first study to evaluate the epidemiology of intussusception hospitalizations among children aged < 24 months in Nepal. Because the public health impact of rotavirus vaccination could be substantial in Nepal, where childhood diarrhea-related morbidity and mortality are high, this baseline knowledge of intussusception prior to introduction of rotavirus vaccine in the national immunization schedule will provide useful information for post-vaccine introduction safety monitoring. PMID- 29169893 TI - Potential for a booster dose of rotavirus vaccine to further reduce diarrhea mortality. AB - Concern has grown that children vaccinated against rotavirus in developing countries may be vulnerable to rotavirus diarrhea in the second year of life due to waning immunity. Adding a booster dose of rotavirus vaccine at 9 or 12 months of age with measles vaccine has been suggested as a strategy to address this. We evaluated the hypothetical potential benefits of a booster dose on reduction of rotavirus mortality. The projected number of deaths averted were calculated using national level full series vaccination coverage, estimated national rotavirus deaths by week of age, and VE at <12 months of age and >=12 months of age derived from the published literature. We assumed three functional forms of waning based on the VE estimates: stepwise, linear, and logarithmic. We modeled three potential boosting scenarios: (a) reduced VE waning in the second year of life by 50%, (b) reestablished second year of life VE to the levels in the first year of life, and (c) boosted first year VE by 50% of the difference between VE in the first and second years. To express uncertainty resulting from the parameters, each of the nine models were run 1000 times using a random sample of input values. Across all WHO regions, with the stepwise models we estimated a median of 9800 (95%CI: 9400, 10,200), 19,600 (95%CI: 18,800, 20,400), and 29,400 (95%CI: 28,200, 30,700) additional rotavirus deaths averted in the reduced VE waning, reestablished VE, and boosted VE scenarios. These estimates were highly sensitive to the assumed functional form of waning with approximately 65-80% fewer deaths averted if immunity waned in a linear or logarithmic fashion compared to the stepwise model. While these projections will benefit from improved input data points, our resultsinform consideration of booster doses of rotavirus vaccine. PMID- 29169895 TI - Additional features of Gillespie syndrome in two Brazilian siblings with a novel ITPR1 homozygous pathogenic variant. AB - Gillespie syndrome (GS) [MIM: 206700] is a very rare condition characterized by bilateral iris defect, congenital hypotonia, cerebellar ataxia and intellectual disability. The typical iris anomaly is considered necessary to the diagnosis of GS. Recently, variants in ITPR1 were described causing GS. Non-neurological features were reported in few patients. Here we describe two consanguineous siblings with GS and a novel homozygous ITPR1 pathogenic variant (p.N984fs). They also present a cardiac defect (pulmonary valve stenosis) and one sib had a genitourinary malformation (ureteropelvic junction obstruction). Our report reinforces ITPR1 as the cause of GS and suggests a possible role of ITPR1 in the development of other organs. PMID- 29169896 TI - The current place of medical therapy in uterine fibroid management. AB - Uterine fibroids (also known as leiomyomas or myomas) are the most common form of benign uterine tumors. Current management strategies mainly involve surgical interventions, but the choice of treatment is guided by patient's age and desire to preserve fertility or avoid "radical" surgery. Surgical and non-surgical approaches include hysterectomy myomectomy by hysteroscopy, myomectomy by laparotomy or laparoscopy, uterine artery embolization, and magnetic resonance guided focused ultrasound surgery. The need for alternatives to surgical intervention is very real, especially for women seeking to preserve their fertility. There is growing evidence of the crucial role of progesterone pathways in the pathophysiology of uterine fibroids, and the efficacy of long-term intermittent use of selective progesterone receptor modulators such as ulipristal acetate was recently demonstrated by randomized controlled studies. PMID- 29169897 TI - Wound healing. AB - Wound healing is an important physiological process to maintain the integrity of skin after trauma, either by accident or by intent procedure. The normal wound healing involves three successive but overlapping phases, including hemostasis/inflammatory phase, proliferative phase, and remodeling phase. Aberration of wound healing, such as excessive wound healing (hypertrophic scar and keloid) or chronic wound (ulcer) impairs the normal physical function. A large number of sophisticated experimental studies have provided insights into wound healing. This article highlights the information after 2010, and the main text includes (i) wound healing; (ii) wound healing in fetus and adult; (iii) prostaglandins and wound healing; (iv) the pathogenesis of excessive wound healing; (v) the epidemiology of excessive wound healing; (vi) in vitro and in vivo studies for excessive wound healing; (vii) stem cell therapy for excessive wound healing; and (viii) the prevention strategy for excessive wound healing.

AB - Recent studies revealing genetic connection of primary open angle glaucoma (POAG) and amyotrophic lateral sclerosis (ALS) have received particular attention. Exploring the evidence for common pathogenesis of these two progressive neurological disorders may assist in understanding the mechanism and searching for new treatment. Retinal nerve fiber layer (RNFL) defect and corresponding visual field (VF) impairment are well known neuropathy signs in glaucoma. In our study, thickness of certain retinal layer in ALS patients was analyzed to detect ganglion cell's soma and axon, and for first time visual field was examined for ALS. The correlation of retinal involvement and ALS progression were also investigated. The results were compared with those of POAG. The study may provide new knowledge for these two neurodegenerative diseases. PMID- 29169900 TI - Cardiotonic actions of quercetin and its metabolite tamarixetin through a digitalis-like enhancement of Ca2+ transients. AB - The plant-derived flavonoid, quercetin (QCT), has many biological actions, including cardioprotective actions, resulting from its antioxidant and anti inflammatory effects. In this study, effects of QCT and its metabolites on the contraction and Ca2+ transients (CaT) of mouse single cardiomyocytes were simultaneously measured and compared with those of isoproterenol and digoxin. Furthermore, cardiac function and plasma concentrations were analyzed after bolus intravenous administration of QCT in mice. QCT and its metabolite, tamarixetin, as well as isoproterenol and digoxin, enhanced the contraction and CaT of cardiomyocytes. The inotropic action of isoproterenol was accompanied by an increase in the velocities of sarcomere shortening and relengthening and CaT decay through activation of cAMP-dependent protein kinase; however, no such lusitropic effects accompanied the inotropic action of QCT, tamarixetin or digoxin. Intravenous administration of QCT to mice resulted in a sustained increase in cardiac systolic function; QCT was rapidly metabolized to tamarixetin and its plasma concentration was maintained at high levels over a similar time frame as the enhancement of cardiac systolic function. These results suggest that QCT exerts a cardiotonic action in vivo at least, in part, through digitalis-like enhancement of CaT by itself and its metabolite tamarixetin. PMID- 29169901 TI - [Transfusion practices in elderly patients: A descriptive study about 241 patients at the university hospital of Brest]. AB - : Red blood cell transfusion is commonly required for elderly patients with little specific guidelines for this population. We wished to study the transfusion practices for patients aged>=75 years transfused with red blood cells in all units of our institution. The aim of this work is to describe this population of patients and to compare the transfusion practices to the HAS and ANSM guidelines published in 2014. METHODS: An observational study was performed including patients>=75 years, transfused with red blood cells between 27th January to 27th March 2014. Analysis of data included the patients' typology, the characteristics of anemia, the indications and transfusion practices, and the adequation with the guidelines. RESULTS: Two hundred and forty-one patients were transfused during the period with 422 transfusion episodes (mean age 83+/-5.2 years, sex-ratio women/men 1.4 with 4.4+/-2 pathologies and 6.7+/-3.2 treatments). Only 4.5% of the patients were transfused in geriatric wards. In 61% of the cases, the anemia is acute and chronic in 39%. Fatigue was reported in 50.6% of the cases and dyspnee in 31.7%. A percentage of 31.1 of the patients were prescribed furosemide for transfusion. The mean transfusion recovery was 1.2+/-0.5g/dL. Two adverse events were reported. Overall, only 10.4% of the prescriptions were not compliant with the guidelines of 2014. CONCLUSION: In this study, we describe transfusion practices for patients aged>=75 years. Although the non-compliance with the guidelines is weak, it is possible to improve the transfusion practices taking care of the geriatric characteristics. Prospective studies on a larger scale have to be done to converge on a more consensual management. PMID- 29169902 TI - [Reversion of overweight and obesity in Vilafranca del Penedes child population: ACTIVA'T Program (2012)]. AB - OBJECTIVE: To assess a 6-month nutritional and physical activity intervention program on the nutritional status of overweight or obese and not very active 8-14 years old children by means of a controlled pre-post design (ACTIVA'T program). METHOD: Pre-post study in 8-14 years old overweight or obese and low active children from Vilafranca del Penedes (Barcelona, Spain) randomized in control group (n = 51, 47.1% girls, nutritional intervention and <=3h/wk physical activity) and ACTIVA'T group (n = 45, 37.8% girls, nutritional and physical activity >=5h/wk intervention). Body mass index, waist/height index, and diet quality by means of KIDMED test at the beginning and at the end of the program were assessed. During the intervention, each participant was accompanied by a relative (father or mother) who performed the same activities as the children. RESULTS: Dietary recommendations have positively changed the habits of both ACTIVA'T and control group. The reversion in the prevalence of overweight and obesity was 93.8% and 58.6%, respectively, in the ACTIVA'T group, compared to 25.0% and 35.8% in the control group. Abdominal obesity was decreased from 42.2% to 17.8% in the ACTIVA'T group and from 47.1% to 27.5% in the control group. CONCLUSIONS: The program ACTIVA'T (nutritional education and physical activity promotion) improves the quality of diet and reverses the prevalence of overweight and obesity in the underactive child population. PMID- 29169903 TI - [New public health challenges in vector management: black flies in Murcia (Spain)]. AB - Historically, no black fly (Diptera: Simuliidae) nuisance has been reported in the Murcia Region. Back in September 2016 the Ojos City Council has contacted the Regional Public Health General Directorate for help regarding a local insect nuisance, most probably based on mosquitoes. After sampling with a BG-sentinel 2 trap, collecting adult specimens with an entomological aspirator, and collect larvae and pupae on submerged giant cane stalks at the river, it turned out that Simulium sergenti was the insect species causing the nuisance. This species is not considered particularly anthropophilic; therefore, a low vector risk for human health was considered. However, the high fly density impaired the life quality of the people at the village. A management plan was recommended, treating the river with Bacillus thuringiensis var israelensis. PMID- 29169905 TI - Fully laparoscopic left hepatectomy - a technical reference proposed for standard practice compared to the open approach: a retrospective propensity score model. AB - BACKGROUND: Laparoscopic left hemihepatectomy (LLH) may be an alternative to open (OLH). There are several original variations in the technical aspects of LLH, and no accepted standard. The aim of this study is to assess the safety and effectiveness of the technique developed at Henri Mondor Hospital since 1996. METHODS: The technique of LLH was conceived for safety and training of two mature generations of lead surgeons. The technique includes full laparoscopy, ventral approach to the common trunk, extrahepatic pedicle dissection, CUSA(r) parenchymal transection, division of the left hilar plate laterally to the Arantius ligament, and ventral transection of the left hepatic vein. The outcomes of LLH and OLH were compared. Perioperative analysis included intra- and postoperative, and histology variables. Propensity Score Matching was undertaken of background covariates including age, ASA, BMI, fibrosis, steatosis, tumour size, and specimen weight. RESULTS: 17 LLH and 51 OLH were performed from 1996 to 2014 with perioperative mortality rates of 0% and 6%, respectively. In the LLH group, two patients underwent conversion to open surgery. Propensity matching selected 10 LLH/OLH pairs. The LLH group had a higher proportion of procedures for benign disease. LLH was associated with longer operating time and less blood loss. Perioperative complications occurred in 30% (LLH) and 10% (OLH) (p = 1). Mortality and ITU stay were similar. CONCLUSION: This technique is recommended as a possible technical reference for standard LLH. PMID- 29169904 TI - Outcomes after vascular resection during curative-intent resection for hilar cholangiocarcinoma: a multi-institution study from the US extrahepatic biliary malignancy consortium. AB - BACKGROUND: Surgical resection is the cornerstone of curative-intent therapy for patients with hilar cholangiocarcinoma (HC). The role of vascular resection (VR) in the treatment of HC in western centres is not well defined. METHODS: Utilizing data from the U.S. Extrahepatic Biliary Malignancy Consortium, patients were grouped into those who underwent resection for HC based on VR status: no VR, portal vein resection (PVR), or hepatic artery resection (HAR). Perioperative and long-term survival outcomes were analyzed. RESULTS: Between 1998 and 2015, 201 patients underwent resection for HC, of which 31 (15%) underwent VR: 19 patients (9%) underwent PVR alone and 12 patients (6%) underwent HAR either with (n = 2) or without PVR (n = 10). Patients selected for VR tended to be younger with higher stage disease. Rates of postoperative complications and 30-day mortality were similar when stratified by vascular resection status. On multivariate analysis, receipt of PVR or HAR did not significantly affect OS or RFS. CONCLUSION: In a modern, multi-institutional cohort of patients undergoing curative-intent resection for HC, VR appears to be a safe procedure in a highly selected subset, although long-term survival outcomes appear equivalent. VR should be considered only in select patients based on tumor and patient characteristics. PMID- 29169906 TI - Limits on normal cochlear 'third' windows provided by previous investigations of additional sound paths into and out of the cat inner ear. AB - While most models of cochlear function assume the presence of only two windows into the mammalian cochlea (the oval and round windows), a position that is generally supported by several lines of data, there is evidence for additional sound paths into and out of the inner ear in normal mammals. In this report we review the existing evidence for and against the 'two-window' hypothesis. We then determine how existing data and inner-ear anatomy restrict transmission of sound through these additional sound pathways in cat by utilizing a well-tested model of the cat inner ear, together with anatomical descriptions of the cat cochlear and vestibular aqueducts (potential additional windows to the cochlea). We conclude: (1) The existing data place limits on the size of the cochlear and vestibular aqueducts in cat and are consistent with small volume-velocities through these ducts during ossicular stimulation of the cochlea, (2) the predicted volume velocities produced by aqueducts with diameters half the size of the bony diameters match the functional data within +/-10 dB, and (3) these additional volume velocity paths contribute to the inner ear's response to non acoustic stimulation and conductive pathology. PMID- 29169907 TI - Upside-down position for the out of hospital management of children with supraventricular tachycardia. AB - BACKGROUND: The upside-down position is a little known modified Valsalva manoeuvre (VM). The aim of this study was to investigate the safety and the efficacy of the upside-down position for the treatment of paroxysmal SVT in children. METHODS: Twenty-four paediatric patients followed for SVT were enrolled. The patients were assigned (1:1) to a standard VM or to an upside-down position at the first episode of SVT at home. If no cardioversion occurred, a second attempt was undertaken with the other VM. At the patient's first relapse, the intervention protocol was applied in the opposite order at home. RESULTS: The upside-down position compared to standard VM reached 67% vs 33% rate of cardioversion at a first attempt, followed by 50% vs 0% rate of cardioversion in patients who had failed the first attempt. After having reversed the order of intervention in case of SVT recurrence, we recorded 67% vs 25% and 71% vs 42% success rates in favour of the upside-down position. There were no adverse events. CONCLUSION: The upside-down position was safe and tended to be more effective than standard VM for out of hospital SVT treatment. Doctors and parents should be more aware of this effective but overlooked manoeuvre. PMID- 29169908 TI - Increased risk and severity of unprovoked venous thromboembolism with clustering cardiovascular risk factors for atherosclerosis: Results of the REMOTEV registry. AB - BACKGROUND: The role of cardiovascular risk factors (CVRF) for atherosclerosis in venous thromboembolic disease (VTE) is controversial. The aim of this study was to evaluate the impact of CVRF and their cumulative effects on the occurrence of unprovoked VTE, severity, recurrence and survival. METHODS AND RESULTS: This is a prospective cohort from the REMOTEV registry including all consecutively hospitalized patients for acute symptomatic VTE. From November 2013 to December 2016, 515 patients with 6months follow-up (FU) were selected for the analysis. Events were classified as unprovoked or provoked VTE. In univariate analysis, hypertension (OR 1.44, [95% CI 1.01-2.06]), diabetes (OR 2.07, [95% CI: 1.25 3.55]) and age (OR 1.94, [95% CI: 1.31-2.88]) were significantly associated with the risk of unprovoked VTE. After adjustment, diabetes (OR 1.82, [95% CI: 1.07 3.18]) and age (OR 1.79, [95% CI: 1.15-2.8]) remained associated with the risk of unprovoked VTE. The proportion of unprovoked VTE increased significantly with the number of CVRF adjusted for thrombophilia (1 CVRF: OR 3 [95% CI: 1.44-6.52]) 2 CVRF: OR 4.33 [95% CI: 2.07-9.49] and >=3 CVRF: OR 4.58 [95% CI: 2.27-9.7]). The severity of pulmonary embolism was significantly associated with CVRF clustering. There were more VTE recurrences and deaths during the 6months of FU with cumulative CVRF. CONCLUSION: The risks of unprovoked VTE and PE severity are associated with clustering CVRF. The role of cumulative CVRF predominates rather than the specific burden of each of the CVRF in the risk of VTE occurrence. PMID- 29169909 TI - Ethyl pyruvate attenuates myocardial ischemia-reperfusion injury exacerbated by hyperglycemia via retained inhibitory effect on HMGB1. AB - BACKGROUND: Hyperglycemia (HG) exacerbates myocardial ischemia/reperfusion (I/R) injury and renders protective strategies ineffective by amplified inflammatory response via enhanced high-mobility group box-1 (HMGB1) release. This study investigated the role of ethyl pyruvate (EP) against myocardial I/R injury under a clinically relevant HG condition. METHODS: Sprague-Dawley rats (n=76) were randomly assigned to 6 groups: normoglycemia (NG)-Sham, NG-I/R-control (C, saline), NG-I/R-EP treatment (50mg/kg) upon reperfusion, HG-Sham, HG-I/R-C, and HG-I/R-EP treatment upon reperfusion. HG was induced by 1.2g/kg dextrose. I/R was induced by ligation of the left anterior descending artery for 30min followed by 4h of reperfusion. RESULTS: HG resulted in exacerbation of myocardial infarct size by 19% with amplified activation of HMGB1-receptors of advanced glycation end products/toll like receptors-NF-kappaB pathway compared to NG following I/R, which all could be attenuated by EP. EP treatment was associated with diminished tumor necrosis factor-alpha, interleukin-1beta, and interleukin-6 expressions. It also served to normalize the increase in pro-apoptotic Bax and the decrease in anti-apoptotic Bcl-2 protein levels. These effects were associated with decreased myocardial apoptosis and infarct size (by 30% and 36% in the NG and HG groups, respectively) regardless of the glycemic condition. CONCLUSION: HG exacerbated myocardial I/R injury through amplified inflammatory response via increased HMGB1 level. EP treatment upon reperfusion conveyed significant myocardial protection against the I/R injury under both NG and HG conditions. Common to both glycemic conditions, associated mechanisms involved attenuated increase in HMGB1 level and suppression of its down-stream pathways. PMID- 29169910 TI - The effect of the number and level of emergency medical technicians on patient outcomes following out of hospital cardiac arrest in Taipei. AB - AIM: The effect of the number and level of on-scene emergency medical technicians (EMTs) on the outcomes of patients with out-of-hospital cardiac arrest (OHCA) remains unclear. We aimed to test the association between the number and level of EMTs and the outcomes of patients with OHCA. METHODS: We analysed Utstein-based registry data on OHCA in Taipei from 2011 to 2015. The eligible patients were adults, aged >=20 years, with non-traumatic OHCA who underwent resuscitation attempts. The exposures were the total number of EMTs or the EMT-Paramedic (EMT P) ratio >50%. The outcome of interest was survival to discharge. RESULTS: During study period, total 8262 OHCA cases were included, of which 1085 (13.1%) were approached by crews with an EMT-P ratio >50%. While an increase in the number of EMTs on-scene was not associated with better chances of survival (adjusted odds ratio [aOR] 0.98, 95% confidence interval [CI] 0.89-1.08), an EMT-P ratio >50% was significantly associated with improved outcome (aOR 1.36, 95% CI 1.06-1.76). Subgroup analyses showed that EMT-P >50% significantly benefited survival in witnessed OHCA cases with non-shockable rhythm (aOR 1.69, 95% CI 1.01-2.58). Survival was the highest among cases seen by four EMTs with an EMT-P ratio >50% (aOR 2.54, 95% CI 1.43-4.50). CONCLUSION: An on-scene EMT-P ratio >50% was associated with improved survival to discharge of OHCA cases, especially in those with witnessed, non-shockable rhythm. The presence of four EMTs with an EMT-P ratio >50% at the scene of OHCA was associated with the best outcome.

PMID- 29169912 TI - Comparison of the Between the Flags calling criteria to the MEWS, NEWS and the electronic Cardiac Arrest Risk Triage (eCART) score for the identification of deteriorating ward patients. AB - INTRODUCTION: Traditionally, paper based observation charts have been used to identify deteriorating patients, with emerging recent electronic medical records allowing electronic algorithms to risk stratify and help direct the response to deterioration. OBJECTIVE(S): We sought to compare the Between the Flags (BTF) calling criteria to the Modified Early Warning Score (MEWS), National Early Warning Score (NEWS) and electronic Cardiac Arrest Risk Triage (eCART) score. DESIGN AND PARTICIPANTS: Multicenter retrospective analysis of electronic health record data from all patients admitted to five US hospitals from November 2008 August 2013. MAIN OUTCOME MEASURES: Cardiac arrest, ICU transfer or death within 24h of a score RESULTS: Overall accuracy was highest for eCART, with an AUC of 0.801 (95% CI 0.799-0.802), followed by NEWS, MEWS and BTF respectively (0.718 [0.716-0.720]; 0.698 [0.696-0.700]; 0.663 [0.661-0.664]). BTF criteria had a high risk (Red Zone) specificity of 95.0% and a moderate risk (Yellow Zone) specificity of 27.5%, which corresponded to MEWS thresholds of >=4 and >=2, NEWS thresholds of >=5 and >=2, and eCART thresholds of >=12 and >=4, respectively. At those thresholds, eCART caught 22 more adverse events per 10,000 patients than BTF using the moderate risk criteria and 13 more using high risk criteria, while MEWS and NEWS identified the same or fewer. CONCLUSION(S): An electronically generated eCART score was more accurate than commonly used paper based observation tools for predicting the composite outcome of in-hospital cardiac arrest, ICU transfer and death within 24h of observation. The outcomes of this analysis lend weight for a move towards an algorithm based electronic risk identification tool for deteriorating patients to ensure earlier detection and prevent adverse events in the hospital. PMID- 29169913 TI - The strategic function of the P5-ATPase ATP13A2 in toxic waste disposal. AB - The P-type ATPase ATP13A2 protein was originally associated with a form of Parkinson's Disease (PD) known as Kufor Rakeb Syndrome (KRS). However, in the last years it has been found to underlay variants of neuronal ceroid lipofuscinoses and hereditary spastic paraplegia. These findings expand the clinical and genetic spectrum of ATP13A2-associated disorders, which are commonly characterized by lysosomal dysfunction. Nowadays it is well known that lysosomes are not merely related to the degradation and recycling of cellular waste, but are also involved in fundamental processes such as secretion, plasma membrane repair, signaling, energy metabolism and autophagy. The essential role of lysosomes in these cellular processes has significant implications for health and disease. ATP13A2 is localized in lysosomes and late endosomes and its mutation leads to lysosome dysfunction, diminishes the exosome secretion and impairs autophagic flux. In this review, we first describe ATP13A2-associated disorders and their relation with the endolysosomal pathway. We then describe the ATP13A2 involvement in iron homeostasis and its potential linkage with new pathologies like cancer, and finally, we consider the putative role of ATP13A2 in lipid processing and degradation, opening the interesting possibility of a broader role of this protein providing protection against a variety of disease-associated changes affecting cellular homeostasis. PMID- 29169914 TI - Low incidence of precore W28* mutant variants in treated hepatitis B virus and human immunodeficiency virus co-infected patients. AB - The precore (pc) W28* mutation arises from immune-selective pressures during the hepatitis B "e" antigen (HBeAg)-positive phase of chronic hepatitis B virus (HBV) infection and has been linked to severe liver-related morbidity. Here, we examined the determinants of harboring this mutation and its rate of emergence in treated patients co-infected with human immunodeficiency virus (HIV) and HBV. In a three-year prospective cohort of 165 HIV-HBV co-infected patients, pcW28* mutation was determined via DNA-chip during yearly sampling. In a subgroup with liver biopsies, HBV covalently-closed circular (ccc)-DNA and total intrahepatic (IH)-DNA were quantified by real-time PCR. From respective inclusion to year-3 visits, median HBV-DNA levels decreased (5.88 log10 IU/mL to <1.78 log10 IU/mL, p < 0.001) and tenofovir-use increased (15.8%-71.4%, p < 0.001). At baseline, 47 of 162 (29.0%) patients had the pcW28* mutation and were more frequently HBeAg negative (adjusted-OR = 4.37, 95%CI = 1.76-10.86) and had non-A HBV genotypes (adjusted-OR = 9.14, 95%CI = 4.05-20.66). No association with HIV-related factors was observed. In 114 patients without baseline mutation and available data, four developed incident pcW28* mutation by the end of follow-up (cumulative 3.5%, 95%CI = 1.3-9.1%). In the 32 patients with liver biopsies, 10 (31.3%) patients harboring the pcW28* mutation had significantly lower adjusted mean cccDNA (0.05 versus without = 0.43 copies/cell, p < 0.001) and total IH-DNA levels (2.31 versus without = 18.59 copies/cell, p = 0.006). In conclusion, the pcW28* mutation infrequently appeared in this co-infected study population with increased use of potent antivirals and suppressed levels of circulating virus.

AB - PURPOSE: To investigate the performance of lissamine green strips from different manufacturers. Additionally, the repeatability, need for sequential dye instillation and impact of repeated lid evertion on lid wiper staining were assessed. METHODS: Study 1 was a prospective, randomised cross-over study where controlled volumes of lissamine green solution prepared from strips (Biotech, Lissaver, GreenGlo, OPGreen) were instilled (right eye: single; left eye: double instillation) on five different days, with OPGreen being tested twice. Lids were everted and digital photographs taken, which were later assessed by a masked observer. Study 2 was an investigator-masked, randomised, controlled study testing the impact of single versus repeated lid evertion. Lid wiper staining was graded (0 to 3 in 0.5 steps). RESULTS: Lid wiper staining differed significantly between lissamine green solutions, with GreenGlo showing the highest amount of staining, and Lissaver the least (all p>0.009). There were no differences in lid wiper staining over two days, using the OPGreen solution (all p>0.05). The number of drops instilled (single versus double) did not significantly affect lid wiper staining (all p>0.05). Repeated lid evertion increased lid wiper staining (p=0.007 when combined with double drop instillation). Light absorbance patterns and measured concentrations aligned with clinical findings. CONCLUSION: There were significant differences in performance between lissamine green solutions. Lid wiper staining was impacted by repeated lid evertion but sequential instillation and use of the Korb grading scale provided little advantage over simpler methods Clinicians must consider this when investigating lid wipers, especially when interpreting a negative finding.

PMID- 29169918 TI - The Use of Body Habitus Reference Images Improves the Ability of Novices to Accurately Estimate Children's Weight Using the PAWPER XL Tape System. AB - BACKGROUND: The original methodology of the PAWPER (Pediatric Advanced Weight Prediction in the Emergency Room) tape relies on a gestalt visual assessment of a child's body habitus to adjust a length-based weight estimation. This assessment is dependent on the user's subjective opinion, which may result in aberrations in accuracy between users and populations. With the development of the second generation PAWPER XL tape, a more objective method of habitus evaluation was desired. OBJECTIVE: The aim of this study was to evaluate a new, more objective figural reference image system and a new checklist system for quantifying body habitus. METHODS: Volunteers were asked to assess the body habitus score of 90 children from a sequence of photographic images using the standard gestalt visual assessment system, a new checklist system, and a system using figural reference images. PAWPER XL tape weight estimations were generated from these scores, which were compared between the three test groups. Participants were also surveyed on their preferences for the different methodologies. RESULTS: There were 11,505 habitus score assessments from 138 doctor, nurse, and paramedic participants. The figural reference image system significantly outperformed the checklist system and the gestalt visual assessment system in terms of weight estimation accuracy, achieving 70.9%, 61.1%, and 60.9% of estimations within 10% of measured weight, respectively. The participants expressed a strong subjective preference for the image system because of speed of use, ease of use, perceived accuracy, objectivity, and low cognitive load. CONCLUSIONS: The figural reference image system was objectively much more accurate than, and subjectively preferable to, the original gestalt visual estimation methodology. PMID- 29169919 TI - Harnessing the native type I-B CRISPR-Cas for genome editing in a polyploid archaeon. AB - Research on CRISPR-Cas (clustered regularly interspaced short palindromic repeats CRISPR associated protein) systems has led to the revolutionary CRISPR/Cas9 genome editing technique. However, for most archaea and half of bacteria, exploitation of their native CRISPR-Cas machineries may be more straightforward and convenient. In this study, we harnessed the native type I-B CRISPR-Cas system for precise genome editing in the polyploid haloarchaeon Haloarcula hispanica. After testing different designs, the editing tool was optimized to be a single plasmid that carries both the self-targeting mini-CRISPR and a 600-800 bp donor. Significantly, chromosomal modifications, such as gene deletion, gene tagging or single nucleotide substitution, were precisely introduced into the vast majority of the transformants. Moreover, we showed that simultaneous editing of two genomic loci could also be readily achieved by one step. In summary, our data demonstrate that the haloarchaeal CRISPR-Cas system can be harnessed for genome editing in this polyploid archaeon, and highlight the convenience and efficiency of the native CRISPR-based genome editing strategy. PMID- 29169920 TI - A glycolysis-based ten-gene signature correlates with the clinical outcome, molecular subtype and IDH1 mutation in glioblastoma. AB - Reprogrammed metabolism is a hallmark of cancer. Glioblastoma (GBM) tumor cells predominantly utilize aerobic glycolysis for the biogenesis of energy and intermediate nutrients. However, in GBM, the clinical significance of glycolysis and its underlying relations with the molecular features such as IDH1 mutation and subtype have not been elucidated yet. Herein, based on glioma datasets including TCGA (The Cancer Genome Atlas), REMBRANDT (Repository for Molecular Brain Neoplasia Data) and GSE16011, we established a glycolytic gene expression signature score (GGESS) by incorporating ten glycolytic genes. Then we performed survival analyses and investigated the correlations between GGESS and IDH1 mutation as well as the molecular subtypes in GBMs. The results showed that GGESS independently predicted unfavorable prognosis and poor response to chemotherapy of GBM patients. Notably, GGESS was high in GBMs of mesenchymal subtype but low in IDH1-mutant GBMs. Furthermore, we found that the promoter regions of tumor promoting glycolytic genes were hypermethylated in IDH1-mutant GBMs. Finally, we found that high GGESS also predicted poor prognosis and poor response to chemotherapy when investigating IDH1-wildtype GBM patients only. Collectively, glycolysis represented by GGESS predicts unfavorable clinical outcome of GBM patients and is closely associated with mesenchymal subtype and IDH1 mutation in GBMs. PMID- 29169921 TI - Cotton functional genomics reveals global insight into genome evolution and fiber development. AB - Due to the economic value of natural textile fiber, cotton has attracted much research attention, which has led to the publication of two diploid genomes and two tetraploid genomes. These big data facilitate functional genomic study in cotton, and allow researchers to investigate cotton genome structure, gene expression, and protein function on the global scale using high-throughput methods. In this review, we summarized recent studies of cotton genomes. Population genomic analyses revealed the domestication history of cultivated upland cotton and the roles of transposable elements in cotton genome evolution. Alternative splicing of cotton transcriptomes was evaluated genome-widely. Several important gene families like MYC, NAC, Sus and GhPLDalpha1 were systematically identified and classified based on genetic structure and biological function. High-throughput proteomics also unraveled the key functional proteins correlated with fiber development. Functional genomic studies have provided unprecedented insights into global-scale methods for cotton research. PMID- 29169922 TI - Site-specific transfer of chromosomal segments and genes in wheat engineered chromosomes. AB - Recently, engineered minichromosomes have been produced using a telomere-mediated truncation technique in some plants. However, the study on transferring genes to minichromosomes is very limited. Here, telomere-mediated truncation was successfully performed in common wheat (Triticum aestivum) to generate stable truncated chromosomes accompanied by a relatively high frequency of chromosomal rearrangements. After the cross between transgenic parents, a promoter-less DsRed gene in a chromosome from one parent was transferred to another chromosome from the other parent at the site behind a maize ubiquitin promoter via the Cre/lox system. DsRed transcripts and red fluorescent proteins were detected in the recombinant plants. In one such seedling, transgenic signals were detected at the centric terminus of chromosome 4D and the distal terminus of chromosome 3A. Clear translocations could be detected at the transgenic loci of these two chromosomes. Intriguingly, signals of centric-specific sequences were co-localized with the translocated D-group chromosomal segment in the terminal region of chromosome 3A. Our results indicate that the Cre/lox system induces the gene swapping to the target chromosome and non-homologous chromosomal recombination simultaneously. These approaches could offer a platform to transfer large DNA fragments or even terminal chromosomal segments to other chromosomes of the natural genome.

AB - OBJECTIVES: To explore the relationship of wet bulb globe temperature (WBGT) on heat-related incidents and alterations in matchplay and behavioural characteristics in women's tennis at the Australian Open. DESIGN: From 360 main draw Australian Open women's matches (2014-2016), data describing on-court calls for trainers, doctors, cooling devices and water, post match medical consults and matchplay characteristics were collated. METHODS: Data were referenced against estimated WBGT and categorised into standard zones (zone 5: >32.3 degrees C, zone 4: 30.1-32.2 degrees C, zone 3: 27.9-30 degrees C, zone 2: 22.3-27.9 degrees C, zone 1: <22.2 degrees C). Generalized linear models assessed the association of WBGT zone on heat-related medical incidences, court call-outs and match characteristics. RESULTS: With an increased estimated WBGT zone, there was an increase in total trainer calls (+19.5%/zone; p=0.019), total doctor calls (+54.1%; p<0.001), total calls for heat related incidents (+55.9%; p<0.001), and cooling devices (+31.4%; p<0.001) calculated from the regression slope. When match characteristics were adjusted for match quality, significant decreases (p<0.001) in the number of winners and net approaches and increase in double faults were associated with increased estimated WBGT zone. CONCLUSIONS: An association between higher estimated WBGT and medical callouts (heat and non-heat related) was evident, with an increased call rate >32 degrees C WBGT, despite no heat-related retirements. As estimated WBGT increased, the number of winners and net approaches were reduced, while double faults increased, particularly >30 degrees C WBGT. Accordingly, the manner in which female players manage and play in the heat during women's Grand Slam tennis appears to change at ~30 degrees C WBGT.

AB - RYR1 mutations, the most common cause of non-dystrophic neuromuscular disorders, are associated with the malignant hyperthermia susceptibility (MHS) trait as well as congenital myopathies with widely variable clinical and histopathological manifestations. Recently, bleeding anomalies have been reported in association with certain RYR1 mutations. Here we report a preterm infant born at 32 weeks gestation with arthrogryposis multiplex congenita due to compound heterozygous, previously MHS-associated RYR1 mutations, with additional signs of prenatal hemorrhage. The patient presented at birth with multiple joint contractures, scoliosis, severe thoracic rigidity and respiratory failure. He continued to depend on mechanical ventilation and tube feeding. Muscle histopathology showed a marked myopathic pattern with eccentric cores. Interestingly, the patient had additional unusual prenatal intraventricular hemorrhage, resulting in post hemorrhagic hydrocephalus as well as epidural hemorrhage affecting the spinal cord. This report adds to the phenotypic variability associated with RYR1 mutations, and highlights possible bleeding complications in affected individuals. PMID- 29169930 TI - Breast Lesion Excision System in the diagnosis and treatment of intraductal papillomas - A feasibility study. AB - OBJECTIVES: This study aims to evaluate the feasibility of Breast Lesion Excision System (BLES) in the treatment of intraductal papillomas. MATERIAL AND METHODS: All patients with a needle biopsy -based suspicion of an intraductal papilloma who consequently underwent a BLES procedure at Helsinki University Hospital between 2011 and 2016 were included in this retrospective study. The purpose of the BLES procedure was either to excise the entire lesion or in few cases to achieve better sampling. RESULTS: In total, 74 patients underwent 80 BLES procedures. Pathological diagnosis after the BLES biopsy confirmed an intraductal papilloma without atypia in 43 lesions, whereas 10 lesions were upgraded to high risk lesions (HRL) with either atypical ductal hyperplasia or lobular carcinoma in situ. Five cases were upgraded to malignancy, two were invasive ductal carcinomas and three were ductal carcinoma in situ. Additionally, 18 lesions were diagnosed as other benign lesions. Four procedures failed. Complete excision with BLES was achieved in 19 out of 43 intraductal papillomas, 6 out of 10 HRL and two out of five malignant lesions. No major complications occurred. The BLES procedure was adequate in the management of the 71 breast lesions. CONCLUSION: The BLES procedure is an acceptable method for the management of small benign and high-risk breast lesions such as intraductal papillomas in selected patients. Thus, a great amount of diagnostic surgical biopsies can be avoided. PMID- 29169931 TI - Aggressive differentiated thyroid cancer. AB - Differentiated thyroid cancer is characteristically associated with an innocuous clinical course, but a minority of cases may manifest surprisingly aggressive behaviour. Such aggressive DTC are directly responsible for the majority of thyroid cancer related deaths. Moreover, they contribute indirectly to increased DTC-related morbidity, because our inability to differentiate these tumours from innocuous DTC at an early stage fuels a significant degree of DTC overtreatment around the globe. In the present paper we describe how improved understanding of the clinicopathological thyroid tumour progression model and optimization of clinical staging systems continues to improve our ability to diagnose and treat aggressive DTC. Early recognition of aggressive DTC allows instillation of an aggressive management strategy which is based upon surgical-oncologic completeness, and minimization of treatment-related sequelae through continued development of reconstructive options and focussed delivery of adjuvant treatments.

PMID- 29169933 TI - Cleaning and disinfection in home care: A comparison of 2 commercial products with potentially different consequences for respiratory health. AB - BACKGROUND: Home care aides perform personal care and homemaking services in client homes, including cleaning and disinfection (C&D). Although C&D are performed to remove soil and dust, they are increasingly performed for infection prevention. Many C&D products contain respiratory irritants. The objective of this study was to evaluate 2 commercial products for C&D effectiveness on common household surfaces in seniors' homes. METHODS: Two C&D visits were conducted in 46 seniors' homes. One visit applied a bleach-containing cleaning product and the other applied an environmentally preferable product. Before and after C&D, the study team performed organic soil bioluminometer measurements on surfaces and collected cotton swab and wipe samples for total bacteria count, Staphylococcus aureus, and Clostridium difficile identification. RESULTS: Both products removed microorganisms from tested surfaces. S aureus was found in 7 households, 1 strain of which was methicillin-resistant. Both products removed S aureus from all surfaces. Bleach-containing products removed somewhat more soil than environmentally preferable products, although results were statistically significant for only 1 surface. CONCLUSIONS: The study showed similar, not identical, C&D performance for 2 cleaning products with potentially different consequences for respiratory health. Additional research is needed to develop robust recommendations for safe, effective C&D in home care. PMID- 29169934 TI - Sustained reduction in rates of hospital-onset Clostridium difficile infection using an automated electronic health record protocol. AB - BACKGROUND: An automated protocol was designed within our electronic medical record (EMR) to help curb the Clostridium difficile problem at our institution. The protocol will identify patients at high risk for C difficile, improve the timing of testing of patients infected on admission, and enhance the appropriateness of C difficile testing throughout the patient's hospitalization. METHODS: Admitted patients with 2 of the following 3 criteria were labeled as high risk for C difficile: admission to a medical institution in the preceding 90 days, administration of antibiotics in the preceding 90 days, or a history of C difficile. High-risk patients with diarrhea in the first 3 days of admission are identified in the EMR, and prompt testing for C difficile is done. After day 3, if diarrhea develops, a series of questions is presented to help test the appropriate patients for C difficile. RESULTS: A statistically significant reduction in rates of hospital-onset C difficile was achieved after implementation of the protocol. CONCLUSIONS: Implementation of an automated protocol for targeted testing of high-risk patients for C difficile was successful at reducing rates of hospital-onset C difficile by improving timing and appropriateness of testing. PMID- 29169935 TI - Survey to explore understanding of the principles of aseptic technique: Qualitative content analysis with descriptive analysis of confidence and training. AB - BACKGROUND: In many countries, aseptic procedures are undertaken by nurses in the general ward setting, but variation in practice has been reported, and evidence indicates that the principles underpinning aseptic technique are not well understood. METHODS: A survey was conducted, employing a brief, purpose-designed, self-reported questionnaire. RESULTS: The response rate was 72%. Of those responding, 65% of nurses described aseptic technique in terms of the procedure used to undertake it, and 46% understood the principles of asepsis. The related concepts of cleanliness and sterilization were frequently confused with one another. Additionally, 72% reported that they not had received training for at least 5 years; 92% were confident of their ability to apply aseptic technique; and 90% reported that they had not been reassessed since their initial training. Qualitative analysis confirmed a lack of clarity about the meaning of aseptic technique. CONCLUSION: Nurses' understanding of aseptic technique and the concepts of sterility and cleanliness is inadequate, a finding in line with results of previous studies. This knowledge gap potentially places patients at risk. Nurses' understanding of the principles of asepsis could be improved. Further studies should establish the generalizability of the study findings. Possible improvements include renewed emphasis during initial nurse education, greater opportunity for updating knowledge and skills post-qualification, and audit of practice. PMID- 29169937 TI - Positive deviance and hand hygiene of nurses in a Quebec hospital: What can we learn from the best? AB - BACKGROUND: Although it is well known that hand hygiene is the most effective measure to prevent health care-associated infections, hand hygiene adherence is low in Quebec, as it is elsewhere. For this study, an innovative framework was used to explore the clinical practice of nurses regarding hand hygiene and the factors that influence it: positive deviance, or the idea that there are people who find better solutions to problems than their peers. This study investigated positive deviance at the level of the care team to shed light on group dynamics. METHODS: We conducted focused ethnographies on 2 care units-a medical-surgery unit and a palliative care unit-at a Montreal university hospital. Data collection consisted mainly of systematic observations and individual interviews with nurses. RESULTS: The results show that positive deviance related to hand hygiene is instigated by social cohesion within a care team, created, in this study, by the mobilizing leadership of the head nurse in the medical-surgery unit and the prevailing humanist philosophy in the palliative care unit. CONCLUSIONS: In health care, it can be useful to apply the positive deviance approach to care teams instead of individuals to better understand the ideologic and structural differences linked to better hand hygiene performance by the nurses. PMID- 29169936 TI - Screening for Clostridium difficile colonization on admission to a hematopoietic stem cell transplant unit may reduce hospital-acquired C difficile infection. AB - Clostridium difficile infection rates are higher in patients undergoing hematopoietic stem cell transplants.

Patient's colonized with C difficile contribute to the overall burden of C difficile infection in hospitals. PMID- 29169938 TI - Correlation between hospital-level antibiotic consumption and incident health care facility-onset Clostridium difficile infection. AB - BACKGROUND: The purpose of this single-center, ecologic study is to characterize the relationship between facility-wide (FacWide) antibiotic consumption and incident health care facility-onset Clostridium difficile infection (HO-CDI). METHODS: FacWide antibiotic consumption and incident HO-CDI were tallied on a monthly basis and standardized, from January 2013 through April 2015. Spearman rank-order correlation coefficients were calculated using matched-months analysis and a 1-month delay. Regression analyses were performed, with P < .05 considered statistically significant. RESULTS: FacWide analysis identified a matched-months correlation between ceftriaxone and HO-CDI (rho = 0.44, P = .018). A unit of stem cell transplant recipients did not have significant correlation between carbapenems and HO-CDI in matched months (rho = 0.37, P = .098), but a significant correlation was observed when a 1-month lag was applied (rho = 0.54, P = .014). DISCUSSION: Three statistically significant lag associations were observed between FacWide/unit-level antibiotic consumption and HO-CDI, and 1 statistically significant nonlagged association was observed FacWide. Antibiotic consumption may convey extended ward-level risk for incident CDI. CONCLUSIONS: Consumption of antibiotic agents may have immediate and prolonged influence on incident CDI. Additional studies are needed to investigate the immediate and delayed associations between antibiotic consumption and C difficile colonization, infection, and transmission at the hospital level. PMID- 29169939 TI - The association between hypercholesterolemia and sitosterolemia, and report of a sitosterolemia kindred. AB - BACKGROUND: Sitosterolemia is associated with increases in intestinal sterol absorption, low-density lipoprotein cholesterol (LDL-C), and cardiovascular disease risk. OBJECTIVE: We examined the relationship between hypercholesterolemia and sitosterolemia in a large population and report a new sitosterolemia case. METHODS: Plasma sterol concentrations were measured by gas chromatography/mass spectrometry, and LDL-C by direct assay. RESULTS: Of 207,926 subjects tested, 4.3% had LDL-C >=190 mg/dL. Plasma beta-sitosterol concentrations >=8.0 mg/L (99th percentile) were found in 4.3% of these subjects vs 0.72% with LDL-C <130 mg/dL. Among all subjects, 0.050% had beta-sitosterol levels >=15.0 mg/L, consistent with sitosterolemia, while among those with LDL-C >=190 mg/dL, 0.334% had this rare disorder. A 13-year-old boy with the highest LDL-C (679 mg/dL) of all subjects had planar xanthomas and a beta-sitosterol level of 53.5 mg/L (normal <3.3 mg/L). He was a compound heterozygote for 2 ABCG8 mutations (p.N409D and an intron 11+2T>A splice site mutation). On a low cholesterol and plant-sterol diet, his LDL-C decreased to 485 mg/dL (-29%) and beta-sitosterol to 44.6 mg/L (-27%). On atorvastatin 20 mg/d, his LDL-C decreased to 299 mg/dL (-38%). With added ezetimibe 10 mg/d, his LDL-C normalized to 60 mg/dL (-80% further decrease); and his beta-sitosterol decreased to 14.1 mg/L ( 68% further decrease). CONCLUSIONS: Our data indicate that about 4% of subjects with LDL-C concentrations >=190 mg/dL have plasma beta-sitosterol concentrations above the 99th percentile and about 0.3% have concentrations consistent with sitosterolemia. Therefore, this diagnosis should be considered in such patients. PMID- 29169940 TI - Enrichment of cellulose acetate nanofibre assemblies for therapeutic delivery of l-tryptophan. AB - The essential amino acid l-tryptophan is naturally present in the body, and is also available as a water soluble dietary supplement. The feasibility of preparing enriched cellulose acetate (CA)-based fibres as a vehicle for therapeutic delivery of such biomolecules was investigated. A new ternary solvent system consisting of acetone: N,N-dimethylacetamide: methanol (2:1:2) has been demonstrated to permit the solution blending of CA with the water soluble l tryptophan. Nanofibrous webs substantially free of structural defects were continuously produced with mean fibre diameters in the range of 520-1010nm, dependent on process parameters. Morphology and diameter of fibres were influenced by concentration of CA spinning solution, applied voltage and flow rates. The kinetic release profile of l-tryptophan from electrospun CA nanofibres was described by the pseudo-second order kinetic model. Fibres with mean diameter of 720nm provide both the highest initial desorption rate and rate constant, which was partially attributed to the low fibre diameter and high relative surface area, but also the fact that the 720nm fibres produced were the most bead free, providing diffusion advantages over the fibres with lowest mean diameter (520nm). The feasibility of combining l-tryptophan within fibres provides a promising route for manufacture of transdermal delivery devices.

AB - Graft copolymerization of chitosan (Ch) with acrylonitrile (AN) prepared by free radical polymerization using potassium persulfate (PPS) as initiator. Optimization of Graft copolymerization of acrylonitrile on to chitosan was performed by studying the main parameters that affecting the grafting process such as initiator and monomer concentrations, reaction time and temperature of the polymerization process to study their influence on percent grafting (G%), grafting efficiency (GE%) and percent homopolymer (H%). Modification of grafted chitosan was done by Schiff's base derivatives using different aldehydes. They are characterized by FT-IR, X-ray diffraction, thermal analysis and scanning electron microscope. Their antibacterial activities against Streptococcus pneumonia (RCMB 010010), Staphylococcus aureus (RCMB 010028), as Gram-positive bacteria and Escherichia coli (RCMB 010052) as Gram-negative bacteria and the antifungal activity against Aspergillus fumigatus (RCMB 02568), Candida albicans (RCMB 05036) and Geotricum candidum (RCMB 05097) were examined using the diffusion agar technique. The obtained data proved that modified chitosan by grafting show better antimicrobial activities than Chitosan. Also Schiff base derivatives showed better antimicrobial activities than grafted chitosan. PMID- 29169942 TI - Injectable hydrogels for delivering biotherapeutic molecules. AB - To date, numerous delivery systems based on either organic or inorganic material have been developed to achieve efficient and sustained delivery of therapeutics. Hydrogels, which are three dimensional networks of crosslinked hydrophilic polymers, have a significant role in solving the clinical and pharmacological limitations of present systems because of their biocompatibility, ease of preparation and unique physical properties such as a tunable porous nature and affinity for biological fluids. Development of an in situ forming injectable hydrogel system has allowed excellent spatial and temporal control, unlike systemically administered therapeutics. Injectable hydrogel systems can offset difficulties with conventional hydrogel-based drug delivery systems in the clinic by forming a drug/gene delivery or cell-growing depot in the body with a single injection, thereby enabling patient compliance and comfort. Carbohydrate polymers are widely used for the synthesis of injectable in situ-forming hydrogels because of ready availability, presence of modifiable functional groups, biocompatibility and other physiochemical properties. In this review, we discuss different aspects of injectable hydrogels, such as bulk hydrogels/macrogels, microgels, and nanogels derived from natural polymers, and their importance in the delivery of therapeutics such as genes, drugs, cells or other biomolecules and how these revolutionary systems can complement existing therapeutic delivery systems. PMID- 29169943 TI - Carboxymethylated iota-carrageenan conjugated amphotericin B loaded gelatin nanoparticles for treating intracellular Candida glabrata infections. AB - Intercellular Candida glabrata infections are difficult to treat due to poor penetration of drugs into the fungal niche. Delivering amphotericin B (Amp B) into the macrophages where the pathogen inhabits is an effective solution. We are studying the macrophage targeting proficiency of iota-carrageenan for the delivery of Amp B using gelatin A nanoparticles (GNPs). The choice of gelatin A was the outcome of in silico inspections where the amino functionalized polymer having the best docking score with Amp B was selected. We prepared a sustained release formulation of amp B loaded carboxymethyl iota-carrageenan conjugated gelatin nanoparticles (CMC-Amp B-GNPs) with size 343+/-12nm and -25+/-5.3mV zeta potential. The formulations were found to be stable, biocompatible and non haemolytic. Flow cytometry analysis showed 3 fold higher uptake of CMC-GNPs compared to the GNPs by RAW 264.7 cells. CMC-Amp B-GNPs showed enhanced antifungal activity than bare Amp B and Amp B-GNPs. PMID- 29169944 TI - A facile comparative approach towards utilization of waste cotton lint for the synthesis of nano-crystalline cellulose crystals along with acid recovery. AB - There is a need for reuse of waste cotton lint (WCL) from the blow room of yarn spinning mills. The drive to use this material for the synthesis of nanocellulose is difficult because of the several purification/pretreatment processes. Here, we developed a combined single bath purification process of WCL and utilized it for the synthesis of nano-crystalline cellulose crystals (NCs) which are valuable nanomaterials with novel properties along with acid recovery for reuse. The micrograph of the synthesized NCs confirmed a network of nano-sized crystalline cellulose crystals having nano ranged diameter of NCs isolated by two processes. The FTIR result established the removal of impurities and hemicelluloses from WCL. The crystallinity index of WCL (~89.97%) is improved to ~96% and ~94% for sulphuric acid and nitric acid synthesized NCs (NC1 and NC2). The crystallite size of WCL, CTWCL, NC1, and NC2 was calculated using XRD and found to be 101.56, 103.54, 98.81, and 95.6nm respectively. The hydrodynamic size (Z-average) (dnm), polydispersity index and zeta potential of NCs was also studied using dynamic light scattering (DLS). The thermal stability of the NC1 is better than that of NC2. These NCs can be used as reinforcing filler/barrier material. PMID- 29169945 TI - Enhanced Antibacterial effect of chitosan film using Montmorillonite/CuO nanocomposite. AB - Montmorillonite -copper oxide (MMT-CuO) nanocomposites were prepared by a facile and eco-friendly method and introduced into chitosan (Cs) matrix to enhance its optical, mechanical and antibacterial properties. The synthesized composites were characterized using diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray (EDX) spectroscopy. The antimicrobial activity of MMT-CuO nanocomposites showed more than 99% mortality against two Gram-negative bacterium (E.coli (PTCC 1270), P.aeruginosa (PTCC 1430)) and two Gram-positive bacterium (S.aureus (PTCC1112) B.cereus (PTCC- 1015)). The effect of weight fraction of MMT-CuO nanocomposites (1, 3 and 5% w/w) as antibacterial nanofiller on physical, optical, mechanical, microstructural, and antibacterial properties of chitosan films were evaluated. The obtained data showed that introducing small amount MMT CuO to chitosan films could enhance the mechanical, antibacterial properties, and decreased both water solubility and UV transition with the lowest effect on the transparency of the films. The incorporation of 3% w/w MMT-CuO-90 nanocomposite into the films increased the tensile strong (TS), and elongation at break (E%) values 58.5% and 52.4%, respectively while reduced the water vapor permeability and oxygen permeability about 55% and 32%, respectively. CSG3MMT-CuO-90 films showed intense antibacterial activity against food borne pathogenic and more effective against S. aureus and B.cereus. than E.coli and P.aeruginosa. PMID- 29169946 TI - Preparation and characterization of chitosan - collagen peptide / oxidized konjac glucomannan hydrogel. AB - In this paper, the microbial transglutaminase (MTGase) was used as a catalyst to graft the collagen peptide (COP) molecules on the amino group of chitosan to obtain water-soluble chitosan-collagen peptide (CS-COP) derivatives. The preparation of composite hydrogel was via the Schiff-base reaction between the amino of CS-COP and the aldehyde of oxidized konjac glucomannan (OKGM). The hydrogels were characterized by various techniques including Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The results of SEM showed that the hydrogel sample had a clear and stable three-dimensional network structure. Meanwhile, these effects of the addition of OKGM on gelation time, swelling behaviors, water evaporation rate and blood coagulation capacity were investigated. The shortest gelation time for hydrogels was 99.3s. The hydrogels showed a good swelling ability and appropriate water retention capacity. The maximum swelling ratio of the hydrogel was 265%. Dynamic blood clotting test showed that the hydrogels materials had good blood coagulation capacity. Moreover, The biocompatibility of hydrogels was evaluated with NIH-3T3 cells by MTT method. The results indicated that the hydrogels exhibited better biocompatibility. Therefore, this hydrogel has a promising potential to be applied as wound dressing. PMID- 29169947 TI - Cu(II)-carboxymethyl chitosan-silane schiff base complex grafted on nano silica: Structural evolution, antibacterial performance and dye degradation ability. AB - O-Carboxymethyl chitosan (OCMC) Schiff's base was utilized for a new class of organic-inorganic hybrid material by grafting it on nano-silica-silane and further metallated with Cu (II). Here (3-Aminopropyl) triethoxysilane (APTES) was used as a linker and 2-hydroxy-1-naphthaldehyde (HN) for Schiff's base formation. The hybrid was characterized by FTIR, TGA, powder XRD, SEM, CHN, DLS, ICP-AES, diffuse reflectance UV-vis and EDX spectroscopic techniques. Magnetization measurements were carried out by VSM at room temperature. This study explored the possible synergic effect of unique properties of carboxymethyl chitosan, Schiff's base Cu (II) complex and nano-silica towards antibacterial activity and in dye degradation studies. The antibacterial performance of nano-hybrid material was examined against both Gram-positive (Escherichia coli) and Gram-negative (Bacillus subtilis) bacteria. The catalytic activity of the hybrid was tested for degradation of reactive black 5 (RB5) through advanced oxidation processes using H2O2 as oxidant. The results show a high dye degradation efficiency of 93% in 130min by the hybrid catalyst with reusability. As per published reports, Chitosan-Schiff's bases show strong antimicrobial activity and their Cu complexes exhibit good catalytic and anticancer activities. Therefore, it is expected that the new organic-inorganic hybrid would be highly applicable in environmental as well as biomedical fields. PMID- 29169948 TI - Biosynthesis of inulin from sucrose using inulosucrase from Lactobacillus gasseri DSM 20604. AB - Inulin is composed of fructose residues connected by beta-(2, 1) glycosidic linkages with many promising physiochemical and physiological properties. In this study, an inulin-producing inulosucrase gene from Lactobacillus gasseri DSM 20604 was cloned, expressed and purified. SDS-PAGE and gel filtration found that the recombinant inulosucrase is a monomeric protein with a molecular weight of 63KDa. The optimal pH for its sucrose hydrolysis and transfructosylation activities was pH 5.5. The optimal temperatures were measured to be 45, 25, and 35 degrees C for sucrose hydrolysis, transfructosylation, and total activity, respectively. Biosynthesis studies showed that the optimal enzyme dosage was 4.5U/g sucrose. Higher sucrose concentrations immensely contributed to inulin biosynthesis; the inulin yield reached its maximum after 1.5h of reaction. Structural analyses of the polysaccharide produced by the recombinant enzyme from sucrose revealed that it is an inulin-type fructan with a molecular weight of 5.858*106Da. PMID- 29169949 TI - High-value utilization of eucalyptus kraft lignin: Preparation and characterization as efficient dye dispersant. AB - The dark color of industrial lignin is the main obstacle for their high value added use in areas such as dyestuff dispersants. A kind of light-colored lignosulfonate with favorable dispersibility and remarkable stain resistance is prepared using fractionated eucalyptus kraft lignin. The fractionated lignins named as D (insoluble part) and X (soluble part) and sulfonated lignin fractions named as SD and SX are characterized by FTIR spectroscopy, 1H NMR spectroscopy, GPC and brightness test. The results reveal that fraction X presents a lower molecular weight but a higher hydroxyl content than that of fraction D, which lead to the differences on the SO3H content, dispersibility and color performance of SD and SX. The sulfonated fractions perform a similar molecular weight to that of unsulfonated lignins and show light color due to the phenolic hydroxyl blocking of 1,4-BS (1,4-butane sultone) and the postprocessing of sodium borohydride. The SX that performs the best of all exhibits obvious decrease on phenolic hydroxyl groups and increase on brightness value which is improved by 85.8% compared with control sample. The SX reaches the highest level (grade 5) in the dispersibility test and presents remarkable stain resistance on different textiles, especially on the dacron and cotton. PMID- 29169950 TI - Lactadherin: An unappreciated haemostasis regulator and potential therapeutic agent. AB - Lactadherin is a small (53-66kDa) multifunctional glycoprotein belonging to the secreted extracellular matrix protein family. It has a multi-domain structure and is involved in many biological and physiological processes, including phagocytosis, angiogenesis, atherosclerosis, tissue remodeling, and haemostasis regulation. Lactadherin binds phosphatidylserine (PS)-enriched cell surfaces in a receptor-independent manner. Interaction between lactadherin and PS is crucial for regulation of blood coagulation processes. This review summarizes recent knowledge on the possible role of lactadherin in haemostasis control, emphasizing the great significance of the interaction between lactadherin and PS expressed on activated platelets and extracellular vesicles. The possible role of lactadherin as a therapeutic target and biomarker is also discussed. PMID- 29169951 TI - Regulation of noradrenergic and serotonergic systems by cannabinoids: relevance to cannabinoid-induced effects. AB - The cannabinoid system is composed of Gi/o protein-coupled cannabinoid type 1 receptor (CB1) and cannabinoid type 2 (CB2) receptor and endogenous compounds. The CB1 receptor is widely distributed in the central nervous system (CNS) and it is involved in the regulation of common physiological functions. At the neuronal level, the CB1 receptor is mainly placed at GABAergic and glutamatergic axon terminals, where it modulates excitatory and inhibitory synapses. To date, the involvement of CB2 receptor in the regulation of neurotransmission in the CNS has not been clearly shown. The majority of noradrenergic (NA) cells in mammalian tissues are located in the locus coeruleus (LC) while serotonergic (5-HT) cells are mainly distributed in the raphe nuclei including the dorsal raphe nucleus (DRN). In the CNS, NA and 5-HT systems play a crucial role in the control of pain, mood, arousal, sleep-wake cycle, learning/memory, anxiety, and rewarding behaviour. This review summarizes the electrophysiological, neurochemical and behavioural evidences for modulation of the NA/5-HT systems by cannabinoids and the CB1 receptor. Cannabinoids regulate the neuronal activity of NA and 5-HT cells and the release of NA and 5-HT by direct and indirect mechanisms. The interaction between cannabinoid and NA/5-HT systems may underlie several behavioural changes induced by cannabis such as anxiolytic and antidepressant effects or side effects (e.g. disruption of attention). Further research is needed to better understand different aspects of NA and 5-HT systems regulation by cannabinoids, which would be relevant for their use in therapeutics. PMID- 29169952 TI - Development and face validation of a Virtual Reality Epley Maneuver System (VREMS) for home Epley treatment of benign paroxysmal positional vertigo: A randomized, controlled trial. AB - PURPOSE: To develop and validate a smartphone based Virtual Reality Epley Maneuver System (VREMS) for home use. METHODS: A smartphone application was designed to produce stereoscopic views of a Virtual Reality (VR) environment, which when viewed after placing a smartphone in a virtual reality headset, allowed the user to be guided step-by-step through the Epley maneuver in a VR environment. Twenty healthy participants were recruited and randomized to undergo either assisted Epleys or self-administered Epleys following reading instructions from an Instructional Handout (IH). All participants were filmed and two expert Otologists reviewed the videos, assigning each participant a score (out of 10) for performance on each step. Participants rated their perceived workload by completing a validated task-load questionnaire (NASA Task Load Index) and averages for both groups were calculated. RESULTS: Twenty participants were evaluated with average age 26.4+/-7.12years old in the VREMS group and 26.1+/ 7.72 in the IH group. The VR assisted group achieved an average score of 7.78+/ 0.99 compared to 6.65+/-1.72 in the IH group. This result was statistically significant with p=0.0001 and side dominance did not appear to play a factor. Analyzing each step of the Epley maneuver demonstrated that assisted Epleys were done more accurately with statically significant results in steps 2-4. Results of the NASA-TLX scores were variable with no significant findings. CONCLUSION: We have developed and demonstrated face validity for VREMS through our randomized controlled trial. The VREMS platform is promising technology, which may improve the accuracy and effectiveness of home Epley treatments. LEVEL OF EVIDENCE: N/A. PMID- 29169953 TI - Total caloric eye speed in patients with vestibular migraine. AB - PURPOSE: Vestibular migraine is a common cause of dizziness that lacks a known objective test. This study examined total eye speed on caloric testing as a diagnostic marker for vestibular migraine. MATERIALS AND METHODS: Retrospective chart review of patients seen in a tertiary otologic practice between 2004 and 2016 who had undergone caloric testing with water irrigation and had a diagnosis of vestibular migraine (n=34). A group of patients with benign paroxysmal positional vertigo (n=10) were used as a control group. Patients were grouped into quartiles based on total eye speed. RESULTS: Only patients in the lowest quartile (total eye speed<79) had a diagnosis of vestibular migraine. All other quartiles included a mix of control and vestibular migraine patients. CONCLUSION: Low total eye speed may be suggestive of a diagnosis of vestibular migraine, but most patients with vestibular migraine do not have low total eye speed. PMID- 29169954 TI - Application of endoscopy in otology: Changes over the last 8years in Korean Otological Society. AB - OBJECTIVES: Despite the worldwide availability of endoscope in otology, it still has not replaced the microscopic surgery as it has for nose surgery. In 2008, we administered a questionnaire on the preference of using otoscopes in Korea. In light of the worldwide availability of endoscopic ear surgery, we have now conducted a more detailed survey to determine if this preference has changed over 8years. SUBJECTS AND METHODS: A questionnaire consisting of 10 questions was used to survey members of the Korean Otological Society who were actively performing middle ear surgery. The responses to this questionnaire were compared to those from 2008. The study also determined the preference for endoscope use based on the surgeon's experience. RESULTS: The mean surgical experience of the otologists was 12.7years. Endoscopy for tympanoplasty and tympanomastoidectomy increased over a period of 8years. In the outpatient clinic, the use of endoscopy also increased; over 8-year period, it surpassed the microscope as the most preferred diagnostic tool in the outpatient clinic. Greater than half of the operating rooms were equipped with endoscopic sets; however, only 4.5% of otologists acknowledged having endoscopic instruments. CONCLUSION: Endoscopy for surgery and in outpatient clinic assessment increased in otology in Korea; however, endoscopes have consistently been used as an adjuvant to the microscope to improve visualization of the tympanic cavity rather than as a tool for totally endoscopic ear surgery. PMID- 29169955 TI - A century and a half of research on the evolution of insect flight. AB - The gill and paranotal lobe theories of insect wing evolution were both proposed in the 1870s. For most of the 20th century, the paranotal lobe theory was more widely accepted, probably due to the fundamentally terrestrial tracheal respiratory system; in the 1970s, some researchers advocated for an elaborated gill ("pleural appendage") theory. Lacking transition fossils, neither theory could be definitively rejected. Winged insects are abundant in the fossil record from the mid-Carboniferous, but insect fossils are vanishingly rare earlier, and all earlier fossils are from primitively wingless insects. The enigmatic, isolated mandibles of Rhyniognatha (early Devonian) hint that pterygotes may have been present much earlier, but the question remains open. In the late 20th century, researchers used models to study the interaction of body and protowing size on solar warming and gliding abilities, and stability and glide effectiveness of many tiny adjustable winglets versus a single, large pair of immobile winglets. Living stoneflies inspired the surface-skimming theory, which provides a mechanism to bridge between aquatic gills and flapping wings. The serendipitously discovered phenomenon of directed aerial descent suggests a likely route to the early origin of insect flight. It provides a biomechanically feasible sequence from guided falls to fully-powered flight. PMID- 29169956 TI - Synovial fluid biomarkers: association with chronic rotator cuff tear severity and pain. AB - BACKGROUND: We tested the hypothesis that biomarkers in the synovial fluid of the glenohumeral (shoulder) joint are correlated with visual analog scale (VAS) scores, functional scores, and ultrasound findings of chronic rotator cuff tear (RCT) severity. METHODS: We measured biomarkers in shoulder joint synovial fluid of 42 patients with partial-thickness (21), nonmassive full-thickness (10), and massive full-thickness (11) RCTs. Pain duration, tear severity, and VAS and functional scores were compared with interleukin (IL) 1beta, IL-6, matrix metalloproteinase (MMP) 1, and MMP-13 levels. RESULTS: Both MMP-1 and MMP-13 levels were significantly highest in the massive full-thickness group. MMP-13 levels were significantly different between groups, but proinflammatory cytokine IL-1beta and IL-6 levels were not. However, IL-1beta levels were significantly positively correlated with VAS (r = 0.66; P <.01) and functional scores (r = 0.61; P <.01), but IL-6, MMP-1, and MMP-13 levels were not. CONCLUSIONS: IL-1beta levels in shoulder synovial fluid correlated positively with shoulder pain and functional scores in patients with chronic RCTs. Both MMP-1 and MMP-13 levels were altered and increased with cuff tear severity. PMID- 29169957 TI - Operative versus nonoperative treatment for the management of full-thickness rotator cuff tears: a systematic review and meta-analysis. AB - BACKGROUND: Rotator cuff disease is the most common pathology of the shoulder, responsible for approximately 70% of clinic visits for shoulder pain. However, no consensus exists on the optimal treatment. The aim of this study was to analyze level I and II research comparing operative versus nonoperative management of full-thickness rotator cuff tears. METHODS: A literature search was performed, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) statement, to identify level I and II studies comparing operative versus nonoperative treatment of rotator cuff tears. Two independent researchers reviewed a total of 1013 articles. Three studies qualified for inclusion. These included 269 patients with 1-year follow-up. The mean age ranged from 59 to 65 years. Clinical outcome measures included the Constant score and visual analog scale (VAS) score for pain. Meta-analysis, using both fixed- and random-effects models, was performed on pooled results to determine overall significance. RESULTS: Statistically significant differences favoring surgery were found in both Constant and VAS scores after 1 year, with mean differences of 5.64 (95% confidence interval, 2.06 to 9.21; P = .002) and -1.08 (95% confidence interval, -1.56 to -0.59; P < .0001), respectively. CONCLUSION: There was a statistically significant improvement in outcomes for patients managed operatively compared with those managed nonoperatively. The differences in both Constant and VAS scores were small and did not meet the minimal difference considered clinically significant. Larger studies with longer follow-up are required to determine whether clinical differences between these treatments become evident over time. PMID- 29169958 TI - Cancer evaluation in the assessment of solid organ transplant candidates: A systematic review of clinical practice guidelines. AB - BACKGROUND: Active malignancies are a contraindication to transplantation, as immunosuppression can lead to worse cancer outcomes; therefore, ensuring transplant candidates are free of malignancy before transplantation is essential. This systematic review assesses the availability, quality, and consistency of recommended cancer evaluation prior to transplantation in Clinical Practice Guidelines (CPGs) for the selection of solid organ transplant candidates. METHODS: We systematically searched for CPGs for the assessment of transplant candidates. The characteristics of included CPGs, strength of recommendations and supporting evidence were extracted. A quality assessment of the CPGs was conducted using the AGREE II tool. RESULTS: We identified 52 CPG for the selection of solid organ transplant candidates. Only 13 (25%) included recommendations for cancer evaluation as part of the assessment of transplant candidates. Most recommended age and sex appropriate cancer screening as per the general population guidelines. Recommendations to evaluate for other malignancies and for high-risk candidates were variable. Most recommendations were based on expert opinion and only two CPGs provided an explicit link between the recommendations and supporting evidence. CONCLUSION: There is a lack of clear and consistent recommendations for pretransplant cancer evaluation in existing CPGs. Although there is some consensus regarding the indication to screen for cancer as per the recommendations for the general population, these recommendations are not an appropriate risk reduction strategy for transplant candidates. Standardized protocols to ensure transplant candidates are cancer free prior to transplantation are needed. PMID- 29169959 TI - Chondrogenic potential of IL-10 in mechanically injured cartilage and cellularized collagen ACI grafts. AB - OBJECTIVE: The application of adjunctive mediators in Autologous chondrocyte implantation (ACI) techniques might be useful for improving the dedifferentiated chondrocyte phenotype, to support neocartilage formation and inhibit post traumatic cartilage destruction. In this study we examined if (a) interleukin 10 treatment can cause chondrogenic phenotype stabilization and matrix preservation in mechanically injured cartilage and if (b) IL-10 can promote chondrogenesis in a clinically applied collagen scaffold for ACI treatment. MATERIALS AND METHODS: For (a) bovine articular cartilage was harvested, subjected to an axial unconfined injury and treated with bovine IL-10 (1-10,000 pg/ng/ml). For (b) a post-operatively remaining ACI graft was treated with human IL-10. Expression levels of type I/II/X collagen, SOX9 and aggrecan were measured by qPCR (a,b). After 3 weeks cell death was analyzed (nuclear blebbing and TUNEL assay) and matrix composition was determined by GAG measurements and immunohistochemistry (aggrecan, type I/II collagen, hyaluronic acid). STATISTICS: One way ANOVA analysis with Bonferroni's correction. RESULTS: (a) IL-10 stabilized the chondrogenic phenotype after injurious compression and preserved matrix integrity. This was indicated by elevated expression of chondrogenic markers COL2A1, ACAN, SOX9, while COL1A1 and COL10A1 were reduced. An increased GAG content paralleled this and histological staining of type 2 collagen, aggrecan and toluidine blue were enhanced after 3 weeks. (b) IL-10 [100 pg/ml] improved the chondrogenic differentiation of human chondrocytes, which was accompanied by cartilaginous matrix formation after 3 weeks of incubation. CONCLUSION: Interleukin-10 is a versatile adjuvant candidate to control the post-injurious environment in cartilage defects and promote chondrogenesis in ACI grafts. PMID- 29169961 TI - The cannabinoid transporter inhibitor OMDM-2 reduces social interaction: Further evidence for transporter-mediated endocannabinoid release. AB - Experimental evidence suggests that the transport of endocannabinoids might work bi-directionally. Accordingly, it is possible that pharmacological blockade of the latter affects not only the re-uptake, but also the release of endocannabinoids, thus preventing them from stimulating CB1 receptors. We used biochemical, pharmacological, and behavioral approaches to investigate the effects of the transporter inhibitor OMDM-2 on social interaction, a behavioral assay that requires activation of CB1 receptors. The underlying mechanisms of OMDM-2 were compared with those of the Fatty Acid Amide Hydrolase (FAAH) inhibitor URB597. Systemic administration of OMDM-2 reduced social interaction, but in contrast to URB597-induced social deficit, this effect was not reversed by the TRPV1 antagonist capsazepine. The CB1 antagonist AM251, which did not affect URB597-induced social withdrawal, exacerbated OMDM-2 effect. In addition, the potent CB1 agonist CP55,940 reversed OMDM-2-, but not URB597-, induced social withdrawal. Blockade of CB1 receptor by AM251 reduced social interaction and the cholecystokinin CCK2 antagonist LY225910 reversed this effect. Similarly, OMDM-2 induced social withdrawal was reversed by LY225910, whereas URB597 effect was not. Elevation of endocannabinoid levels by URB597 or JZL184, an inhibitor of 2 AG degradation, failed to reverse OMDM-2-induced social withdrawal, and did not show additive effects on cannabinoid measurements when co-administered with OMDM 2. Taken together, these findings indicate that OMDM-2 impaired social interaction in a manner that is consistent with reduced activation of presynaptic CB1 receptors. As cannabinoid reuptake inhibitors may impair endocannabinoid release, caution should be taken when using these drugs to enhance endocannabinoid tone in vivo. PMID- 29169960 TI - Oxytocin inhibits the rat medullary dorsal horn Sp5c/C1 nociceptive transmission through OT but not V1A receptors. AB - The medullary dorsal horn (MDH or Sp5c/C1 region) plays a key role modulating the nociceptive input arriving from craniofacial structures. Some reports suggest that oxytocin could play a role modulating the nociceptive input at the MDH level, but no study has properly tested this hypothesis. Using an electrophysiological and pharmacological approach, the present study aimed to determine the effect of oxytocin on the nociceptive signaling in the MDH and the receptor involved. In sevoflurane, anesthetized rats, we performed electrophysiological unitary recordings of second order neurons at the MDH region responding to peripheral nociceptive-evoked responses of the first branch (V1; ophthalmic) of the trigeminal nerve. Under this condition, we constructed dose response curves analyzing the effect of local spinal oxytocin (0.2-20 nmol) on MDH nociceptive neuronal firing. Furthermore, we tested the role of oxytocin receptors (OTR) or vasopressin V1A receptors (V1AR) involved in the oxytocin effects. Oxytocin dose-dependently inhibits the peripheral-evoked activity in nociceptive MDH neurotransmission. This inhibition is associated with a blockade of neuronal activity of Adelta- and C-fibers. Since this antinociception was abolished by pretreatment (in the MDH) with the potent and selective OTR antagonist (L-368,899; 20 nmol) and remained unaffected after the V1AR antagonist (SR49059; 20 nmol or 200 nmol), the role of OTR is implied. This electrophysiological study demonstrates that oxytocin inhibits the peripheral evoked neuronal activity at MDH, through OTR activation. Thus, OTR may represent a new potential drug target to treat craniofacial nociceptive dysfunction in the MDH. PMID- 29169962 TI - Impaired peripheral glucose homeostasis and Alzheimer's disease. AB - Alzheimer's disease (AD) is the most common type of dementia. Recent studies suggest that metabolic disturbances, particularly type 2 diabetes (T2D) increase the risk of cognitive decline and AD. AD is also a risk factor for T2D, and a growing body of evidence indicates that these diseases are connected both at clinical and molecular levels. In T2D, peripheral insulin resistance, hyperglycemia and eventually insulin deficiency develops, leading to an overall decline in tissue health. More recently, brain insulin resistance has been shown to be a key feature of AD that is linked to neuronal dysfunction and cognitive impairment. Furthermore, both AD and T2D are amyloidogenic diseases, with abnormal aggregation of amyloid-beta peptide (Abeta) and islet amyloid polypeptide (IAPP) respectively contributing to cellular death and disease pathogenesis. Emerging data suggests that Abeta may have peripheral effects including its co-deposition in the pancreas. In this review, we discuss how peripheral effects of Abeta and metabolic disturbances may impact AD pathogenesis.

AB - OBJECTIVE: The objective of this study was to evaluate a sample of electronic medical records (EMR) that was sufficiently representative of the different areas of care in a university hospital, as well as to verify the effectiveness of an initial intervention through a second evaluation. METHODS: Medical records audits were performed in 2012 and 2013 by a blind peer review of random samples of care episodes, proportional to the activity of each clinical department, and with the same evaluation method being applied to all of them. RESULTS: More than 1,000 episodes of care were reviewed in the 2audits. A significant improvement was found in hospital admissions (P=.000) in all the sections of the EMR analysed (P=.002), and was especially significant for the reason for consultation, for which its completion increased by 8.5% (p<.05), and also in the sections of the current process record (7.1%), physical examination (4.7%), allergies (3.9%), and clinical course (3.6%). The assessment of the discharge report, as a whole, showed an improvement (P=.001). In outpatient follow-up visits, a significant positive improvement was observed in the 4sections evaluated (P<.05), and also overall (P=.000). CONCLUSIONS: According to study conditions, the dissemination of the results was effective in improving the quality of the EMR. The results have made it possible to implement actions to review the work processes in certain departments, and also the partial redesign of the interface on being a reproducible methodology accepted by the organisation. PMID- 29169964 TI - [Integral incident management system in primary care: Beyond patient safety]. AB - OBJECTIVE: To describe an integral system of notification and management of incidents, created by the Primary Care Team of Guineueta, as well as the main results after 18 months of implementation. MATERIAL AND METHOD: Using a simple online form, health professionals notified any type of, already categorised, incident. Each of them were distributed to an improvement team that assessed and performed the necessary actions. In addition, the Quality Committee immediately assessed the ones that affected patient safety, as well as the most relevant or repetitive ones every 6 months. RESULTS: During the first 18 months of operation of the system, the health professionals reported 1,267 incidents, most notably informatics, maintenance/technical assistance, and errors in scheduling, in internal circuits and protocols. Eight of them were considered to significantly affect patient safety. CONCLUSIONS: The implementation of the described system has been consolidated into our team, facilitating the detection of problems, the accomplishment of improvement actions and involving the professionals in the improvement of the quality. PMID- 29169965 TI - [Social capital as a determinant of public health]. AB - BACKGROUND: The concept of Social Capital (SC), originally described by Durkheim (1893), is composed of dimensions related to cohesion and trust between members of a social group, and considered by the Word Health Organization (WHO) as part of the social determinants of public health for the decrease of inequities and inequalities in health provision. OBJECTIVE: To contribute to the dissemination of the concept of SC related to the social determinants of Public Health, in order to offer the reader in-depth content to observe the potential applications and practices in this field. METHODOLOGY: Literature search (Google AcademicsTM, PubMed, Science directTM, Ebsco HostTM). RESULTS: A total of 294 full-text publications were obtained, and those selected were the most influential sources on the evolution and application of the concept of Social Capital, socioeconomic development and health in the last decade. CONCLUSION: Although the current evidence shows that Social Capital is a determinant related to health, standards are still needed for its measurement. This could allow the concept to be measured, and facilitate its integration into the form of actions that exert positive influence and contribute to the implementation of institutional interventions planned for development and public health. PMID- 29169966 TI - The Finnish Prehospital Stroke Scale Detects Thrombectomy and Thrombolysis Candidates-A Propensity Score-Matched Study. AB - BACKGROUND: Prehospital stroke triage is challenged by endovascular treatment for large vessel occlusion (LVO) being available only in major stroke centers. Conjugate eye deviation (CED) is closely related to LVO, whereas common stroke signs (face-arm-leg-speech-visual) screen stroke. We hypothesized that combining CED with common stroke signs would yield a prehospital stroke scale for identifying both LVO and stroke in general. METHODS AND RESULTS: We retrospectively analyzed consecutive patients (n = 856) with prehospital Code Stroke (recanalization candidate). The National Institutes of Health Stroke Scale (NIHSS) and computed tomography were administered to patients on arrival. Computed tomography angiography was performed on patients with NIHSS score of 8 or greater and considered to benefit from endovascular treatment. With random forest analysis and deviance analysis of the general linear model we confirmed the superiority of the NIHSS "Best Gaze" over other NIHSS items in detecting LVO. Based on this and commonly used stroke signs we presented the Finnish Prehospital Stroke Scale (FPSS) including dichotomized face drooping, extremity weakness, speech difficulty, visual disturbance, and CED. FPSS detected LVO with a sensitivity of 54%, specificity of 91%, positive predictive value of 48%, negative predictive value of 93%, and likelihood ratio of 6.2. CONCLUSIONS: Based on CED and universally used stroke signs, FPSS recognizes stroke in general and additionally, LVO as a stroke subtype comparably to other scales intended to detect LVO only. As the FPSS items are dichotomized, it is likely to be easy for emergency medical services to implement. PMID- 29169967 TI - Relationship between Risk Factor Control and Compliance with a Lifestyle Modification Program in the Stenting Aggressive Medical Management for Prevention of Recurrent Stroke in Intracranial Stenosis Trial. AB - BACKGROUND: Lifestyle modification programs have improved the achievement of risk factor targets in a variety of clinical settings, including patients who have previously suffered a stroke or transient ischemic attack and those with multiple risk factors. Stenting Aggressive Medical Management for Prevention of Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) was the first vascular disease prevention trial to provide a commercially available lifestyle modification program to enhance risk factor control. We sought to determine the relationship between compliance with this program and risk factor control in SAMMPRIS. METHODS: SAMMPRIS aggressive medical management included a telephonic lifestyle modification program provided free of charge to all subjects (n = 451) during their participation in the study. Subjects with fewer than 3 expected lifestyle coaching calls were excluded from these analyses. Compliant subjects (n = 201) had greater than or equal to 78.5% of calls (median % of completed/expected calls). Noncompliant subjects (n = 200) had less than 78.5% of calls or refused to participate. Mean risk factor values or % in-target for each risk factor was compared between compliant versus noncompliant subjects, using t tests and chi square tests. Risk factor changes from baseline to follow-up were compared between the groups to account for baseline differences. RESULTS: Compliant subjects had better risk factor control throughout follow-up for low-density lipoprotein, systolic blood pressure (SBP), hemoglobin A1c (HgA1c), non-high density lipoprotein, nonsmoking, and exercise than noncompliant subjects, but there was no difference for body mass index. After adjusting for baseline differences between the groups, compliant subjects had a greater change from baseline than noncompliant subjects for SBP did at 24 months and HgA1c at 6 months. CONCLUSION: SAMMPRIS subjects who were compliant with the lifestyle modification program had better risk factor control during the study for almost all risk factors. PMID- 29169968 TI - Evaluation of several clinical parameters after bleaching with hydrogen peroxide at different concentrations: A randomized clinical trial. AB - OBJECTIVE: This randomized double-blind clinical trial compared tooth sensitivity (TS), bleaching efficacy, and cytokine levels after applying in-office bleaching treatments containing 15% and 35% hydrogen peroxide (HP15% and HP35%, respectively). METHODS: Twenty-five volunteers were randomly assigned to receive HP15% or HP35% treatment. The bleaching agent was applied in three 15-min applications per session. Two bleaching sessions were separated by a 1-week interval. The participants scored TS using a visual analog scale and numerical rating scale. Bleaching efficacy was determined by subjective and objective methods. Gingival crevicular fluid was collected from three jaws sites per patient for the analysis of fluid volume. Flow cytometry was used to analyze gingival crevicular fluid levels of interleukin (IL)-1beta, IL-2, IL-4, IL-6, IL 10, tumor necrosis factor, and interferon-gamma. All measurements were obtained before and after bleaching. All data were statistically analyzed (alpha=0.05). RESULTS: The absolute risk and intensity of TS was higher for HP35% than for HP15% (p>0.002). One month post-bleaching, HP35% produced more bleaching than HP15% (p=0.02). However patient perception (p=0.06) and patient satisfaction (p=0.53) with regard to bleaching were not significantly different. No significant differences existed in the gingival fluid volume (p>0.38) or in any cytokine level (p>0.05) for either HP concentration. CONCLUSION: Treatment: with HP35% is more effective than HP15%, but generates a greater risk and intensity of TS. No inflammatory changes occurred despite the difference in the HP concentrations. CLINICAL SIGNIFICANCE: Hydrogen peroxide at a lower concentration (e.g., 15%) should be considered a good treatment alternative for in-office bleaching because the higher concentration for in-office bleaching generates a greater risk and intensity of TS for patients. PMID- 29169970 TI - Bark cells and xylem cells in Japanese white birch twigs initiate deacclimation at different temperatures. AB - Appropriate timing of cold deacclimation is an important component of winter survival of perennial plants, such as trees, in temperate and boreal zones. Recently, concerns about predicted global climate change disturbing deacclimation timing have been increasing. The relationship between ambient temperatures and the manner by which cells' freezing resistance changes is essential for forecasting the timing of deacclimation. In this study, Japanese white birch twigs that underwent deacclimation treatment at a constant temperature of -2, 0, 4, 10, or 20 degrees C were separated into bark in which cells adapted to subfreezing temperatures by extracellular freezing and xylem in which cells adapted to subfreezing temperatures by deep supercooling, and the freezing resistance of cells in each tissue type was investigated by measuring percentage electrolyte leakage. Birch cells deacclimated in a different manner according to tissue type. Within 7 days under deacclimation treatment, xylem cells decreased their freezing resistance significantly at a high subfreezing temperature (-2 degrees C). In contrast, bark cells required a temperature of 10 or 20 degrees C for a detectable decrease in freezing resistance to occur within the same period. At a temperature lower than 0 degrees C, bark cells did not decrease their freezing resistance, even after 28 days of treatment. The difference in freezing behavior of cells might involve the difference in how deacclimation occurred in bark and xylem cells. PMID- 29169969 TI - Higher experience of caries and lower income trajectory influence the quality of restorations: A multilevel analysis in a birth cohort. AB - OBJECTIVES: This study aimed to evaluate the quality of posterior restorations (amalgam or composite) placed in adults from a birth cohort and its association with clinical and socioeconomic determinants experienced during their life course. METHODS: A representative sample (n=539) of all 5914 births occurring in Pelotas (Brazil) in 1982 was prospectively investigated. Quality of posterior restorations (satisfactory or unsatisfactory) was assessed at 31 yrs-old, using modified USPHS criteria. Trained and calibrated dentists performed clinical examination. Explanatory variables included demographic and socioeconomic, oral health and dental service utilization patterns during the life course. Tooth related variables (type of tooth, material, size of cavity) were also analyzed. Untreated caries and socioeconomic status were assessed by group-based trajectories analyses. Multilevel Regression models were used to determine factors associated with restoration outcomes. RESULTS: In total 2123 restorations (53% composite) were evaluated of which 107 (5%) were assessed as failed. The main reasons for failure were tooth/restoration fracture (50.5%) and secondary caries (30.7%). Failures in posterior restorations showed a significant association with socioeconomic aspects (lower tertile of income at age 30 - prevalence ratio (PR) 2.21 [95% CI 1.19-4.09]), clinical variables (trajectory of higher untreated caries - PR 2.11 [95% CI 1.23-3.61]) and also with tooth-related factors (Restorations involving three or more surfaces - PR 5.51 [95% CI 3.30 9.19]) after adjustment for each other. CONCLUSIONS: These findings suggest that, although tooth-related variables have an important role in restoration longevity, patient-related factors, such as socioeconomic variables and untreated caries are also associated with failure and should be taken into account when evaluating longevity of posterior restorations. CLINICAL SIGNIFICANCE: This was the first study assessing long-term trajectory of untreated caries, showing an association between higher experience of caries during the life-course and unsatisfactory restorations. The findings suggest that individual related factors should be considered when planning treatment and in future research evaluating the longevity of dental restorations. PMID- 29169971 TI - Comparison of prostate distortion by inflatable and rigid endorectal MRI coils in permanent prostate brachytherapy imaging. AB - PURPOSE: To study the deformation of the prostate by a rigid reusable endorectal coil and a balloon-type endorectal coil (BTC) during MRI of the prostate in brachytherapy imaging. METHODS AND MATERIALS: The prostate gland was contoured on 157 MRI scans from 52 prostate cancer patients undergoing brachytherapy. The curvature of the posterior prostate surface deformation was computed as a measure of prostate distortion and compared between scans with a BTC, rigid endorectal coil (REC), or no endorectal coil. For the nine patients who had MRIs with all three endorectal scenarios, a mean prostate deformation vector was also calculated between scenarios using deformable image registration. These measures of prostate distortion were compared with the prostate anterior-to-posterior to left-to-right ratio (AP/LR) on the largest prostate axial slice. RESULTS: Significant differences in prostate curvature were found between scans without an endorectal coil versus a REC versus a BTC (p < 0.001). The mean prostate deformation was 3.9 mm due to the BTC and 2.0 mm for the REC (p = 0.012). The mean AP/LR ratio was 0.62 with a BTC versus 0.76 without a coil or 0.73 with a REC (p < 0.001), but no difference existed between scans with a REC versus no coil (p = 0.7). The AP/LR ratio showed moderate correlation with prostate curvature (r = 0.48), and with mean prostate deformation (r = -0.64 to 0.68). CONCLUSIONS: The REC caused minimal deformation of the prostate compared with a BTC with adequate MR image quality, and calculation of the cross-sectional AP/LR ratio on the largest axial prostate slice can serve as a simple measure of prostate distortion. PMID- 29169972 TI - Detection of circulating IgG autoantibody to FcepsilonRIalpha in sera from chronic spontaneous urticaria patients. AB - BACKGROUNDS: Chronic spontaneous urticaria (CSU) is a common skin disorder characterized by itchy wheals of at least 6 weeks in duration, wherein the autoimmune mechanism is involved to activate IgE receptors (FcepsilonRIalpha) on mast cells. We aimed to assess levels of IgG autoantibody against FcepsilonRIalpha in sera from CSU patients using dot-blot immunoassay. METHODS: We performed a hospital-based cross-sectional study of 125 CSU patients (64 ASST positive, 61 ASST-negative) and 64 age-and sex-matched healthy controls. The cut off value of IgG FcepsilonRIalpha autoantibody was determined as the mean intensity plus two standard deviations of values in controls. Positivity for IgG autoantibody to FcepsilonRIalpha was analyzed according to clinical parameters of disease duration, urticaria activity score (UAS), ASST, response to antihistamine treatment, complement levels, and the presence of other autoantibodies. Nonparametric tests were applied for statistical analyses. RESULTS: IgG positivity to FcepsilonRIalpha was noted in 24.8% of CSU patients and was significantly more frequent in ASST-positive patients than in ASST-negative patients (32.8% vs 16.4%, P = 0.040). Only 3.1% of healthy controls had this autoantibody. Complement 3 levels were significantly lower in anti FcepsilonRIalpha antibody-positive patients than antibody-negative patients (109.8 +/- 19.9 vs 123.1 +/- 30.9, P = 0.035). No significant associations were found between IgG positivity to FcepsilonRIalpha and UAS, serum total IgE levels, atopic status, clinical responses to antihistamines, or the presence of anti thyroid and anti-nuclear antibodies. CONCLUSION: These findings suggest that circulating IgG autoantibody to FcepsilonRIalpha in a subset of patients may be involved in the autoimmune mechanism of CSU. Further studies are needed to clarify its clinical significance. PMID- 29169973 TI - [Maternal death by venous thromboembolic disease]. AB - Pregnancy and postpartum are very high-risk periods for venous thromboembolism events (TEE), which seems to extend far beyond the classical 6-8 weeks after childbirth. Pulmonary embolism (PE) is one of the 3 main causes of direct maternal death in western countries. Between 2010 an 2012 in France, 24 deaths were related to PE giving a maternal mortality ratio of 1/100,000, which is not different from the former report (2007-2009). PE is responsible of 9% of maternal deaths, in equal position with postpartum hemorrhage and amniotic fluid embolism. Four deaths (16%) occurred after pregnancy interruption (1 abortion, 3 medical interruptions), 7 (30%) during ongoing pregnancy (before 22 weeks of pregnancy) and 13 (54%) in the postpartum period (9 to 60 days after childbirth). Among these deaths, 9 occurred in extra hospital setting (at home or in the street). Fifty percent of these deaths seem to be avoidable, as it was in the former report. Main avoidability criteria were: diagnostic delay; mobilization before effective anticoagulation of proximal deep venous thrombosis; insufficient preventive treatment with low molecular weight heparin [duration and/or dose (obesity)]; unjustified induction of labor. Analyzing those deaths allow to remind that in case of high suspicion of TEE, effective anticoagulation should be started without delay, and that angio-TDM is not contraindicated in pregnant women. Low molecular weight heparin regiment should be adapted to real weight. Monitoring of anti-Xa activity, if not routinely recommended, is probably useful in case of obesity or renal insufficiency. Anticipating birth by induction of labor, in the absence of abnormal fetal heart rhythm, should not delay effective anticoagulation of near-term TEE. PMID- 29169974 TI - A Prospective, Multicenter Phase II Study of the Efficacy and Feasibility of 15 minute Panitumumab Infusion Plus Irinotecan for Oxaliplatin- and Irinotecan refractory, KRAS Wild-type Metastatic Colorectal Cancer (Short Infusion of Panitumumab Trial). AB - BACKGROUND: In some recently updated clinical guidelines, the fully humanized monoclonal antibody panitumumab, combined with irinotecan, has been recommended as an optional third-line chemotherapy for KRAS wild-type metastatic colorectal cancer (mCRC). The present prospective, multicenter phase II study evaluated the effectiveness and safety of short 15-minute panitumumab infusions. PATIENTS AND METHODS: From January 2011 to December 2011, patients with KRAS wild-type mCRC were enrolled at 8 centers. The key eligibility criteria were age >= 20 years and resistance or intolerance to irinotecan, fluoropyrimidine, and oxaliplatin. All patients received 6 mg/kg of panitumumab and 150 mg/m2 or the previous tolerated dose of irinotecan, biweekly, until disease progression or unacceptable toxicity. The initial panitumumab infusion was 60 minutes, followed by a 30-minute infusion and then 15-minute infusions. The primary endpoint was the confirmed response rate using Response Evaluation Criteria In Solid Tumors, version 1.0. The secondary endpoints were progression-free survival, overall survival, and toxicity. The trial is registered in the University Hospital Medical Information Network Clinical Trials Registry (UMIN no. 000004647). RESULTS: Of the 43 patients, the median age was 62 years (range, 32-75 years), 58% were male, and the Eastern Cooperative Oncology Group performance status was 0 to 1. The total response rate was 37.2% (95% confidence interval [CI], 23.0-53.3), and the confirmed response rate was 18.6% (95% CI, 8.4-33.4). The median progression-free and overall survival were 5.8 months (95% CI, 3.3-8.4 months) and 13.6 months (95% CI, 10.8-16.5 months), respectively. The most frequent grade 3/4 toxicities were anorexia (12%), leukopenia (9%), and neutropenia (9%). Nine patients did not reach the 15-minute infusion, primarily because of disease progression. No infusion-related reactions were observed. CONCLUSION: The short 15-minute panitumumab infusion regimen was well tolerated, without compromising safety or efficacy in patients with KRAS wild-type, oxaliplatin- and irinotecan-refractory mCRC.

AB - OBJECTIVES: To determine the prevalence of psychiatric disorders in primary care pediatrics in Atlantic Galicia. METHODS: An observational, descriptive, cross sectional prevalence study was carried out in 9 outpatient clinics in A Coruna and Pontevedra with a population of 8293 children between September and November 2015. A total of 1286 randomly selected patients from 0 to 14 years of age were included. From the medical history was registered: age, sex, psychiatric diagnosis established by DSM-IV-TR criteria in its five axes, professionals who participated in the diagnosis and treatment of the process and what type of treatment was received. Authorization was obtained from the Research Ethics Committee of Galicia number 2015/427. RESULTS: 148 of 1286 patients presented psychiatric pathology (11,5% IC 95% 9.73-13,29), 68% male. Between 0 and 5years, the prevalence was 4.5%; between 6y and 10y, 18.5% and between 11y and 14y 22%. Symptoms lasted a median of 25 months. The most frequent pathologies in 1286 patients were ADHD (5.36%), language disorders (3.42%), learning disorders (3.26%), anxiety-depressive disorders (2.4%) and behavior disorders (1.87%). Of the 148 cases, 47% had comorbidity with another mental disorder. Most of them required attention by multiple social, health and educational professionals; 33% received psychopharmacological treatment. CONCLUSIONS: The prevalence of psychiatric disorders in pediatric primary care is frequent, chronic and complex, increases with age and requires many health, educational and social resources.

PMID- 29169981 TI - Effects of different levels of feed intake during four short periods of gestation and housing systems on sows and litter performance. AB - The current study investigated the effects of different levels of feed intake during 4 short periods of gestation and of housing systems on sow and litter performance. A total of 255 multiparous sows were allotted to 1-4 dietary treatments using a randomized complete block design blocking by initial body weight (BW), backfat (BF) and parity. Sows were housed either in individual stalls (n=129) or group pens (n=126) with 55 sows in each pen with electronic sow feeder during gestation. All sows were fed one common corn-soybean meal-based diet with the amount of 1.0*maintenance energy level of feed intake (106*BW0.75) throughout gestation except 4 periods of 7 d when dietary treatments were imposed on day 27, 55, 83 and 97 of gestation. During the 4 periods, sows were fed 1 of 4 different levels of feed intake: 0.5, 1.0, 1.5 and 2.0*maintenance energy level (0.5M, 1.0M, 1.5M and 2.0M, respectively). Results showed that both BW gain and BF change during gestation for sows on 1.5M (49.7kg and 3.1mm, respectively) and 2.0M (52.5kg and 3.7mm, respectively) levels of feed intake were significantly (P<0.01) greater than sows on 0.5M (26.1kg and -0.1mm, respectively) and 1.0M (35.6kg and 0.1, respectively) levels of feed intake. In contrast, lactation weight gain for sows on 1.5M (3.3kg) and 2.0M (3.4kg) levels of feed intake during 4 short periods of gestation were significantly (P<0.01) less than sows on 0.5M (18.4kg) and 1.0M (11.4kg) levels of feed intake during 4 short periods of gestation, whereas BF loss during lactation for sows on 1.5M (-3.6mm) level of feed intake during 4 short periods of gestation were significantly (P=0.03) higher than sows on 1.0M (-2.1mm) level of feed intake during 4 short periods of gestation. Additionally, average daily feed intake during lactation for sows on 0.5M (6.6kg/d) level of feed intake during gestation tended (P=0.06) to be greater than sows on 2.0M (5.9kg/d) level of feed intake. There were no differences (P>0.1) among 4 levels of feed intake in terms of numbers of total born and weaning piglets. However, both piglet weight at birth (1.46, 1.52, 1.53 and 1.51kg for piglets from sows on 0.5M, 1.0M, 1.5M and 2.0M levels of feed intake during gestation, respectively) and at weaning (6.37, 6.55, 6.64 and 6.38kg for piglets from sows on 0.5M, 1.0M, 1.5M and 2.0M levels of feed intake during gestation, respectively) were maximized at 1.5M level of feed intake. Sows housed in group pens had greater (P<0.01) net BW gain (24.7 vs. 19.2kg) from day 27 of gestation to weaning compared with sows housed in individual stalls. However, there were no differences (P>0.1) between the 2 housing systems in terms of litter size and piglet weight at birth and at weaning. In conclusion, increasing levels of feed intake during 4 short periods of gestation increased BW and BF gain during gestation and led to less BW gain and more BF loss during lactation. Piglet weight at birth and at weaning was maximized at 1.5M level of feed intake. However, housing systems did not affect reproductive performance. Group pen housing system may be beneficial in terms of increased overall BW gain during gestation and lactation. PMID- 29169982 TI - Systematic isolated post-dilatation of the side branch as part of the provisional stent technique in the percutaneous treatment of coronary bifurcations. CR12 Registry. AB - AIMS: To analyse systematic isolated post-dilatation of the side branch as a part of provisional stent technique. METHODS: 1960 angioplasties performed in two centres were prospectively registered, of which 382 were coronary bifurcations with a side branch>2mm. In centre A, isolated post-dilatation of the side branch was performed regardless its impairment after main vessel stenting. In centre B, side branch post-dilatation was performed only if it was severely affected after stent implantation. RESULTS: There was no difference between the two centres in the rate of side branch affection after stent implantation (A: 44.6 vs B: 49.3%, p=0.48) nor in the procedural success rate (A: 98.6% vs B: 96.7%, p=0.45). After one-year follow-up, a reduction of cardiovascular events was observed in centre A (A: 4.4% vs B: 10.4%, p=0.043) with a trend towards lower cardiac mortality (A: 2.2% vs B: 6.5%, p=0.093) and stent thrombosis (A: 0% vs B: 2.6%, p=0.077). There were no differences in the rate of myocardial infarction related to the treated artery (A: 1.4% vs B: 3.9%, p=0.29), or target lesion revascularization (A: 1.4% vs. B: 3.2%, p=0.45). CONCLUSIONS: Systematic isolated post-dilatation of the side branch in the provisional stent technique was associated with a high angiographic success rate, and a low rate of cardiovascular events during follow up. Although the study design does not allow definitive conclusions, this strategy could be considered a valid option in some cases or even as part of the provisional stent technique. PMID- 29169983 TI - Novel proctorship effectively teaches interventionists coronary artery chronic total occlusion lesions. AB - BACKGROUND: Interventionists' experience and skills are essential factors for successful chronic total occlusion-percutaneous coronary intervention (CTO-PCI). However, the construction of theoretical strategy independent from interventionists' procedure may also improve it. We sought to assess the feasibility of CTO-PCI using an educational system supported by a single expert proctor. METHODS: A total of 160 patients underwent CTO-PCI between 2009 and 2016 at 92 Japanese centers in the Hands-on proctorship project. The CTO-PCI strategy was discussed with all participants and their specialists, before and during the procedure. We divided patients into 2 groups based on the CTO-PCI experience of their interventionist: (1) the less experienced group (CTO-PCI <=50 cases, n=65) and (2) the more experienced group (CTO-PCI >50 cases, n=95). Baseline characteristics, procedural complications, and clinical outcomes were compared between groups. RESULTS: No significant differences in patient age, sex, prevalence for coronary risk factors, and lesion complexity was observed between groups. The retrograde approach was used equivalently between groups (55.4% vs. 60.0%, p=0.56), and procedural success rates were similar (96.9% vs. 90.5%, p=0.12). The rate of proctor's bailout for recanalization were not frequent between groups (4.6% vs. 5.3%, p=0.85). No procedure-related mortality was noted in either group. In addition, no significant differences in procedural cardiac complications, including coronary dissection, perforation, or tamponade, were observed between groups (10.8% vs. 14.7%, p=0.47). CONCLUSIONS: The expert supported CTO-PCI maintained high success rates regardless of interventionists' experience. This highlights the importance of theoretical strategy for the management patients undergoing CTO-PCI. PMID- 29169984 TI - Left Main restenosis in the DES era - a call for action. AB - Percutaneous treatment of the unprotected left main trunk (ULM), defined as a vessel without patent bypass graft either to the left circumflex (LCX) or left anterior descending (LAD) artery, has gained a precise role thanks to recent scientific evidence. Although new generation drug-eluting stents have already proven to be safer, there is still a consistent risk of restenosis and late adverse events. The optimal management of a ULM restenosis is still debated. Here we aim at presenting a review of the available data in literature and show our choice for treating it.

PMID- 29169988 TI - The Versican G1 Fragment and Serum-Derived Hyaluronan-Associated Proteins Interact and Form a Complex in Granulation Tissue of Pressure Ulcers. AB - The hyaluronan (HA)-rich extracellular matrix plays dynamic roles during tissue remodeling. Versican and serum-derived HA-associated protein (SHAP), corresponding to the heavy chains of inter-alpha-trypsin inhibitor, are major HA binding molecules in remodeling processes, such as wound healing. Versican G1 domain fragment (VG1F) is generated by proteolysis and is present in either remodeling tissues or the mature dermis. However, the macrocomplex formation of VG1F has not been clarified. Therefore, we examined the VG1F-containing macrocomplex in pressure ulcers characterized by chronic refractory wounds. VG1F colocalized with SHAP-HA in specific regions of the granulation tissue but not with fibrillin-1. A unique VG1F-SHAP-HA complex was isolated from granulation tissues using gel filtration chromatography and subsequent cesium chloride gradient ultracentrifugation under dissociating conditions. Consistent with this molecular composition, recombinant versican G1, but not versican G3, interacted with the two heavy chains of inter-alpha-trypsin inhibitor. The addition of recombinant VG1 in fibroblast cultures enhanced VG1F-SHAP-HA complex deposition in the pericellular extracellular matrix. Comparison with other VG1F-containing macrocomplexes, including dermal VG1F aggregates, versican-bound microfibrils, and intact versican, highlighted the tissue-specific organization of HA-rich extracellular matrix formation containing versican and SHAP. The VG1F-SHAP-HA complex was specifically detected in the edematous granulation tissues of human pressure ulcers and in inflamed stages in a mouse model of moist would healing, suggesting that the complex provides an HA-rich matrix suitable for inflammatory reactions.

AB - Visceral adiposity is of greater risk than obesity in s.c. adipose tissue for diabetes and cardiovascular disease. Its pathogenesis remains unclear, but it is associated with extracellular matrix (ECM) remodeling. A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTSs) are a family of secreted zinc-dependent metalloproteinases that play crucial roles in development and various diseases because of their ECM remodeling activity. ADAMTS18 is an orphan ADAMTS whose function and substrate remain unclear. Herein, we showed that Adamts18 mRNA was abundantly expressed in visceral (gonadal) white adipose tissue (vWAT) during the early stage of development after birth. Adamts18 knockout (KO) mice showed increased body fat percentage and larger adipocyte size in vWAT relative to wild-type littermates. These findings may be partly attributed to ECM remodeling, especially increased expression of laminin 1 and adipokine thrombospondin 1 in vWAT. Attenuated extracellular signal-regulated kinase 1 and 2 activity, along with increased expression of adipocyte-specific transcription factors peroxisome proliferator-activated receptor-gamma, CCAAT/enhancer binding protein beta, and marker gene Fabp4, was detected in vWAT of Adamts18 KO mice. Furthermore, Adamts18 KO mice showed early metabolic syndrome, including hyperlipidemia, blood glucose metabolic disorder, and hypertension. ADAMTS18 deficiency promotes atherosclerosis in apolipoprotein E-deficient mice. These results indicate a novel function of ADAMTS18 in vWAT development and associated metabolic disorders. PMID- 29169987 TI - The R-Enantiomer of Ketorolac Delays Mammary Tumor Development in Mouse Mammary Tumor Virus-Polyoma Middle T Antigen (MMTV-PyMT) Mice. AB - Epidemiologic studies report improved breast cancer survival in women who receive ketorolac (Toradol) for postoperative pain relief compared with other analgesic agents. Ketorolac is a racemic drug. The S-enantiomer inhibits cyclooxygenases; R ketorolac is a selective inhibitor of the small GTPases Ras-related C3 botulinum toxin substrate 1 (Rac1) and cell division control protein 42 (Cdc42), which are signaling molecules up-regulated during breast cancer progression and metastasis. The goal of this study was to determine whether R-ketorolac altered breast cancer development in the mouse mammary tumor virus-polyoma middle T-antigen model. Mice were administered ketorolac orally at 1 mg/kg twice daily to approximate the typical human dose. Mammary glands were analyzed for tumor number and immunohistochemical markers of proliferation and differentiation. R-ketorolac treatment significantly reduced mammary epithelial proliferation, based on Ki67 staining, and suppressed tumor development. Proliferative mammary epithelium from R-ketorolac-treated mice displayed greater differentiation, based on significantly higher total E-cadherin and decreased keratin 5 staining than epithelium of placebo-treated mice. No differences were detected in estrogen receptor, progesterone receptor, beta-catenin, or vimentin expression between placebo and R-ketorolac treatment groups. These findings indicate that R ketorolac treatment slows tumor progression in an aggressive model of breast cancer. R-ketorolac may thus represent a novel therapeutic approach for breast cancer prevention or treatment based on its pharmacologic activity as a Rac1 and Cdc42 inhibitor. PMID- 29169990 TI - Lack of Heme Oxygenase-1 Induces Inflammatory Reaction and Proliferation of Muscle Satellite Cells after Cardiotoxin-Induced Skeletal Muscle Injury. AB - Heme oxygenase-1 (HO-1, Hmox1) regulates viability, proliferation, and differentiation of many cell types; hence, it may affect regeneration of injured skeletal muscle. Here, we injected cardiotoxin into gastrocnemius muscle of Hmox1+/+ and Hmox1-/- animals and analyzed cellular response after muscle injury, focusing on muscle satellite cells (SCs), inflammatory reaction, fibrosis, and formation of new blood vessels. HO-1 is strongly induced after muscle injury, being expressed mostly in the infiltrating leukocytes (CD45+ cells), including macrophages (F4/80+ cells). Lack of HO-1 augments skeletal muscle injury, evidenced by increased creatinine kinase and lactate dehydrogenase, as well as expression of monocyte chemoattractant protein-1, IL-6, IL-1beta, and insulin like growth factor-1. This, together with disturbed proportion of M1/M2 macrophages, accompanied by enhanced formation of arterioles, may be responsible for shift of Hmox1-/- myofiber size distribution toward larger one. Importantly, HO-1-deficient SCs are prone to activation and have higher proliferation on injury. This effect can be partially mimicked by stimulation of Hmox1+/+ SCs with monocyte chemoattractant protein-1, IL-6, IL-1beta, and is associated with increased MyoD expression, suggesting that Hmox1-/- SCs are shifted toward more differentiated myogenic population. However, multiple rounds of degeneration/regeneration in conditions of HO-1 deficiency may lead to exhaustion of SC pool, and the number of SCs is decreased in old Hmox1-/- mice. In summary, HO-1 modulates muscle repair mechanisms preventing its uncontrolled acceleration. PMID- 29169991 TI - Progression of Type 2 Helper T Cell-Type Inflammation and Airway Remodeling in a Rodent Model of Naturally Acquired Subclinical Primary Pneumocystis Infection. AB - Subclinical primary Pneumocystis infection is the most common pulmonary infection in early infancy, making it important to determine whether it damages the lung. Pneumocystis peaks at 2 to 5 months of age, when respiratory morbidity coincidently increases. We have documented that Pneumocystis increases mucus production in infant lungs, and animal models reveal lung lesions that warrant characterization. Herein, immunocompetent rats infected at birth with Pneumocystis by cohabitation, to resemble community-acquired infection, underwent lung assessments at 45, 60, and 75 days of age. Lungs fixed by vascular perfusion to prevent collapse during necropsy were used for morphometry evaluations of mucus production, airway epithelial thickening, perivascular and peribronchiolar inflammation, and structural airway remodeling. Changes in these histologic features indicate lung disease. Selected immune markers were assessed in parallel using fresh-frozen lung tissue from sibling rats of the same cages. Sequential activation of NF-kappaB and an increased Gata3/T-bet mRNA level ratio, consistent with a type 2 helper T-cell-type inflammatory response, and subacute fibrosis were recognized. Therefore, documenting subclinical Pneumocystis infection induces lung disease in the immunocompetent host. Taken together with the peak age of primary Pneumocystis infection, results warrant investigating the clinical impact of this often subclinical infection on the severity of respiratory diseases in early infancy. This model can also be used to assess the effects of airway insults, including coinfections by recognized respiratory pathogens. PMID- 29169994 TI - The Limitations of "How Are You Feeling?" PMID- 29169993 TI - Impact of vitamin D on pregnancy-related disorders and on offspring outcome. AB - Observational studies from all over the world continue to find high prevalence rates of vitamin D insufficiency and deficiency in many populations, including pregnant women. Beyond its classical function as a regulator of calcium and phosphate metabolism, vitamin D elicits numerous effects in the human body. Current evidence highlights a vital role of vitamin D in mammalian gestation. During pregnancy, adaptations in maternal vitamin D metabolism lead to a physiologic increase of vitamin D levels, mainly because of an increased renal production, although other potential sources like the placenta are being discussed. A sufficient supply of mother and child with calcium and vitamin D during pregnancy ensures a healthy bone development of the fetus, whereas lack of either of these nutrients can lead to the development of rickets in the child. Moreover, vitamin D insufficiency during pregnancy has consistently been associated with adverse maternal and neonatal pregnancy outcomes. In multitudinous studies, low maternal vitamin D status was associated with a higher risk for preeclampsia, gestational diabetes mellitus and other gestational diseases. Likewise, several negative consequences for the fetus have been reported, including fetal growth restriction, increased risk of preterm birth and a changed susceptibility for later-life diseases. However, study results are diverging and causality has not been proven so far. Meta-analyses on the relationship between maternal vitamin D status and pregnancy outcomes revealed a wide heterogeneity of studied populations and the applied methodology in vitamin D assessment. Until today, clinical guidelines for supplementation cannot be based on high-quality evidence and it is not clear if the required intake for pregnant women differs from non-pregnant women. Long-term safety data of vitamin D supplementation in pregnant women has not been established and overdosing of vitamin D might have unfavorable effects, especially in mothers and newborns with mutations of genes involved in vitamin D metabolism. Reliable data from large observational and interventional randomized control trials are urgently needed as a basis for any detailed and safe recommendations for supplementation in the general population and, most importantly, in pregnant women. This is of utmost importance, as ensuring a sufficient vitamin D-supply of mother and child implies a great potential for the prevention of birth complications and development of diseases. PMID- 29169992 TI - HAX-1 regulates SERCA2a oxidation and degradation. AB - Ischemia/reperfusion injury is associated with contractile dysfunction and increased cardiomyocyte death. Overexpression of the hematopoietic lineage substrate-1-associated protein X-1 (HAX-1) has been shown to protect from cellular injury but the function of endogenous HAX-1 remains obscure due to early lethality of the knockout mouse. Herein we generated a cardiac-specific and inducible HAX-1 deficient model, which uncovered an unexpected role of HAX-1 in regulation of sarco/endoplasmic reticulum Ca-ATPase (SERCA2a) in ischemia/reperfusion injury. Although ablation of HAX-1 in the adult heart elicited no morphological alterations under non-stress conditions, it diminished contractile recovery and increased infarct size upon ischemia/reperfusion injury. These detrimental effects were associated with increased loss of SERCA2a. Enhanced SERCA2a degradation was not due to alterations in calpain and calpastatin levels or calpain activity. Conversely, HAX-1 overexpression improved contractile recovery and maintained SERCA2a levels. The regulatory effects of HAX 1 on SERCA2a degradation were observed at multiple levels, including intact hearts, isolated cardiomyocytes and sarcoplasmic reticulum microsomes. Mechanistically, HAX-1 ablation elicited increased production of reactive oxygen species at the sarco/endoplasic reticulum compartment, resulting in SERCA2a oxidation and a predisposition to its proteolysis. This effect may be mediated by NAPDH oxidase 4 (NOX4), a novel binding partner of HAX-1. Accordingly, NOX inhibition with apocynin abrogated the effects of HAX-1 ablation in hearts subjected to ischemia/reperfusion injury. Taken together, our findings reveal a role of HAX-1 in the regulation of oxidative stress and SERCA2a degradation, implicating its importance in calcium homeostasis and cell survival pathways. PMID- 29169995 TI - Toward a Fully Fledged Integration of Spiritual Care and Medical Care. AB - In this article, we aimed to set out current problems that hinder a fully fledged integration of spiritual and medical care, which address these obstacles. We discuss the following five statements: 1) spiritual care requires a clear and inclusive definition of spirituality; 2) empirical evidence for spiritual care interventions should be improved; 3) understanding patients' experiences of contingency is paramount to deliver effective spiritual care; 4) attention to spiritual needs of patients is a task for every health care practitioner; 5) courses on spirituality and spiritual care should be mandatory in the medical curriculum. Current problems might be overcome by speaking each other's language, which is crucial in interdisciplinary research and in good interdisciplinary collaboration. Using a clear and inclusive definition of spirituality and substantiating spiritual care using medical standards of evidence-based practice is a way to speak each other's language and to increase mutual understanding. Furthermore, including spirituality in the medical curriculum would raise awareness of medical practitioners for their task of attending to patients' spiritual needs and, subsequently, to better and more appropriate referral for spiritual care. PMID- 29169996 TI - Analysis of different anthropometric indicators in the detection of high blood pressure in school adolescents: a cross-sectional study with 8295 adolescents. AB - BACKGROUND: High blood pressure is strongly associated with obesity in different populations. However, it is unclear whether different anthropometric indicators of obesity can satisfactorily predict high blood pressure in the school setting. OBJECTIVES: This study evaluated the sensitivity and specificity of body mass index, waist circumference, and waist to height ratio in the detection of high blood pressure in adolescents. METHODS: The sample consisted of 8295 adolescents aged 10-17 years. Weight was measured using a digital scale, height with a stadiometer, and waist circumference using a tape measure. Blood pressure was measured by an automatic blood pressure measuring device. ROC curves were used for the analysis of sensitivity and specificity of the three anthropometric indices in identifying high blood pressure. Binary Logistic Regression was used to assess the association of body mass index, waist circumference, and waist to height ratio with high blood pressure. RESULTS: Low values of sensitivity were observed for body mass index (0.35), waist circumference (0.37), and waist to height ratio (0.31) and high values of specificity for body mass index (0.86), waist circumference (0.82), and waist to height ratio (0.83) in the detection of high blood pressure. An association was observed between adolescents classified with high body mass index (OR=3.57 [95% CI=3.10-4.10]), waist cirumference (OR=3.24 [95% CI=2.83-3.72]), and waist to height ratio (OR=2.94 [95% CI=2.54 3.40]) with high blood pressure. CONCLUSIONS: Body mass index, waist circumference, and waist to height ratio presented low sensitivity to identify adolescents with high blood pressure. However, adolescents classified with high body mass index, waist circumference, and waist to height ratio demonstrated a high association of presenting high blood pressure. PMID- 29169998 TI - Interaction between DRD2 and lead exposure on the cortical thickness of the frontal lobe in youth with attention-deficit/hyperactivity disorder. AB - BACKGROUND: The dopamine receptor D2 receptor (DRD2) gene and lead exposure are both thought to contribute to the pathophysiology of attention deficit/hyperactivity disorder (ADHD). ADHD is characterized by delay in brain maturation, most prominent in the prefrontal cortex (PFC). The D2 receptor is also mainly located in the PFC, and animal studies show that lead exposure affects the dopaminergic system of the frontal lobe, indicating an overlap in neural correlates of ADHD, DRD2, and lead exposure. We examined the interaction effects of DRD2 rs1800497 and lead exposure on the cortical thickness of the frontal lobe in patients with ADHD. METHODS: A 1:1 age- and gender-matched sample of 75 participants with ADHD and 75 healthy participants was included in the analysis. The interaction effects of DRD2 and lead exposure on the cortical thickness of 12 regions of interest in the frontal lobe were examined by multivariable linear regression analyses. RESULTS: When we investigated the DRD2*lead effects in the ADHD and HC groups separately, significant DRD2*lead effects were found in the ADHD group, but not in the healthy control group in multiple ROIs of the frontal lobe. There was a significant negative correlation between the cortical thickness of the right superior frontal gyrus and inattention scores. CONCLUSIONS: The present findings demonstrated significant interaction effects of DRD2 and lead exposure on the cortical thickness of the frontal lobe in ADHD. Replication studies with larger sample sizes, using a prospective design, are warranted to confirm these findings. PMID- 29169999 TI - Current challenges in research in suicide. PMID- 29169997 TI - PSD95: A synaptic protein implicated in schizophrenia or autism? AB - The molecular components of the postsynaptic density (PSD) in excitatory synapses of the brain are currently being investigated as one of the major etiologies of neurodevelopmental disorders such as schizophrenia (SCZ) and autism. Postsynaptic density protein-95 (PSD-95) is a major regulator of synaptic maturation by interacting, stabilizing and trafficking N-methyl-d-aspartic acid receptors (NMDARs) and alpha-amino-3-hydroxy-5-methyl-4-isox-azoleproprionic acid receptors (AMPARs) to the postsynaptic membrane. Recently, there has been overwhelming evidence that associates PSD-95 disruption with cognitive and learning deficits observed in SCZ and autism. For instance, recent genomic and sequencing studies of psychiatric patients highlight the aberrations at the PSD of glutamatergic synapses that include PSD-95 dysfunction. In animal studies, PSD-95 deficiency shows alterations in NMDA and AMPA-receptor composition and function in specific brain regions that may contribute to phenotypes observed in neuropsychiatric pathologies. In this review, we describe the role of PSD-95 as an essential scaffolding protein during synaptogenesis and neurodevelopment. More specifically, we discuss its interactions with NMDA receptor subunits that potentially affect glutamate transmission, and the formation of silent synapses during critical time points of neurodevelopment. Furthermore, we describe how PSD 95 may alter dendritic spine morphologies, thus regulating synaptic function that influences behavioral phenotypes in SCZ versus autism. Understanding the role of PSD-95 in the neuropathologies of SCZ and autism will give an insight of the cellular and molecular attributes in the disorders, thus providing treatment options in patients affected. PMID- 29170000 TI - Sleep disorder and altered locomotor activity as biomarkers of the Parkinson's disease cholinopathy in rat. AB - In order to find out the possible earliest biomarkers of Parkinson's disease (PD) cholinopathy, we followed the impact of bilateral pedunculopontine tegmental nucleus (PPT) lesion in rat on: the cortical and hippocampal sleep/wake states architectures, all sleep states related EEG microstructures, sleep spindles, the basal and stimulated locomotor activity. Sleep and basal locomotor activity in adult Wistar rats were followed during their inactive circadian phase, and throughout the same aging period. The bilateral PPT lesions were done by 0.1M ibotenic acid (IBO) during the surgical procedure for implantation of the electroencephalographic (EEG) and electromyographic (EMG) electrodes for chronic sleep recording. The cholinergic neuronal loss was identified by NADPH - diaphorase histochemistry. After all sleep and behavioral recording sessions, the locomotor activity was stimulated by d-amphetamine (d-AMPH) and the neuronal activity of striatum was followed by c-Fos immunolabeling. Impaired cholinergic innervation from the PPT was expressed earlier as sleep disorder then as movement disorder, and it was the earliest and long-lasting at hippocampal and thalamo cortical level, and followed by a delayed "hypokinesia". This severe impact of a tonically impaired PPT cholinergic innervation was evidenced as the cholinergic interneuronal loss of the caudate putamen and as a suppressed c-Fos expression after stimulation by d-AMPH. In order how they occurred, the hippocampal non rapid eye movement (NREM) sleep disorder, altered high voltage sleep spindle (HVS) dynamics during rapid eye movement (REM) sleep in the hippocampus and motor cortex, and "hypokinesia" may serve as the biomarkers of PD cholinopathy onset and progression. PMID- 29170001 TI - Heightened cortisol response to exercise challenge in women with functional hypothalamic amenorrhea. AB - BACKGROUND: Functional hypothalamic amenorrhea is characterized by anovulation caused by reduced gonadotropin-releasing hormone drive and is associated with hypercortisolemia that has been linked to heightened hypothalamic-pituitary adrenal reactivity to common psychological and metabolic challenges. OBJECTIVE: We hypothesized that women with functional hypothalamic amenorrhea would display greater cortisol responses to exercise challenge than ovulatory women with eumenorrhea. STUDY DESIGN: We completed a cross-sectional comparison of 9 women with functional hypothalamic amenorrhea and 11 women with eumenorrhea who were of reproductive age, who weighed 90-110% ideal body weight, who did not exercise excessively, and who had no formal psychiatric diagnosis. Subjects completed a 20 minute submaximal exercise challenge using a cycle ergometer in a research exercise laboratory. Heart rate and circulatory cortisol, glucose, and lactate were measured at 10-minute intervals before, during, and after the exercise challenge. RESULTS: Baseline (t= -10 minutes) cortisol, glucose, lactate, and heart rate were comparable between groups. Glucose levels rose modestly during exercise by 2.9% in women with eumenorrhea (P=.4) but declined by 10.6% in functional hypothalamic amenorrhea (P<.03). The nadir in glucose levels in functional hypothalamic amenorrhea occurred at the end of the 20-minute exercise challenge (t= +20 min). Lactate levels rose comparably in both groups (P<.01). Heart rate increased significantly with exercise in both groups (P<.01), but the increase was smaller in subjects with functional hypothalamic amenorrhea (P<.01). Cortisol levels increased during the exercise challenge in both groups (P<.01) and peaked 10 minutes after the exercise ended (t= +30 min). At peak, subjects with functional hypothalamic amenorrhea displayed higher cortisol levels (147+/ 22 [standard error of the mean] ng/mL) than women with eumenorrhea (96+/-12 ng/mL; P=.05). The mean percent increase over baseline was 62% in women with eumenorrhea and 92% in functional hypothalamic amenorrhea. CONCLUSION: The heightened cortisol response to exercise in women with functional hypothalamic amenorrhea was associated with a decline in blood glucose level that was not observed in women with eumenorrhea. Women with functional hypothalamic amenorrhea appear to be more reactive at the endocrine level to the metabolic demand of exercise. Submaximal challenge unmasks underlying stress sensitivity in women with functional hypothalamic amenorrhea and highlights the importance of the use of psychological interventions for stress reduction in this population.

PMID- 29170003 TI - Exploring the functional significance of sterol glycosyltransferase enzymes. AB - Steroidal alkaloids (SAs) are widely synthesized and distributed in plants manifesting as natural produce endowed with potential for medicinal, pesticidal and other high-value usages. Glycosylation of these SAs raises complex and diverse glycosides in plant cells that indeed govern numerous functional aspects. During the glycosylation process of these valuable metabolites, the addition of carbohydrate molecule(s) is catalyzed by enzymes known as sterol glycosyltransferases (SGTs), commonly referred to as UGTs, leading to the production of steryl glycosides (SGs). The ratio of SGs and nonglyco-conjugated SAs are different in different plant species, however, their biosynthesis in the cell is controlled by different environmental factors. The aim of this review is to evaluate the current SGT enzyme research and the functional consequences of glycomodification of SAs on the physiology and plant development, which together are associated with the plant's primary processes. Pharmaceutical, industrial, and other potential uses of saponins have also been discussed and their use in therapeutics has been unveiled by in silico analysis. The field of biotransformation or conversion of nonglycosylated to glycosylated phytosterols by the activity of SGTs, making them soluble, available and more useful for humankind is the new field of interest towards drug therapy. PMID- 29170004 TI - Identifying Patient Attitudinal Clusters Associated with Asthma Control: The European REALISE Survey. AB - BACKGROUND: Asthma is a highly heterogeneous disease that can be classified into different clinical phenotypes, and treatment may be tailored accordingly. However, factors beyond purely clinical traits, such as patient attitudes and behaviors, can also have a marked impact on treatment outcomes. OBJECTIVE: The objective of this study was to further analyze data from the REcognise Asthma and LInk to Symptoms and Experience (REALISE) Europe survey, to identify distinct patient groups sharing common attitudes toward asthma and its management. METHODS: Factor analysis of respondent data (N = 7,930) from the REALISE Europe survey consolidated the 34 attitudinal variables provided by the study population into a set of 8 summary factors. Cluster analyses were used to identify patient clusters that showed similar attitudes and behaviors toward each of the 8 summary factors. RESULTS: Five distinct patient clusters were identified and named according to the key characteristics comprising that cluster: "Confident and self managing," "Confident and accepting of their asthma," "Confident but dependent on others," "Concerned but confident in their health care professional (HCP)," and "Not confident in themselves or their HCP." Clusters showed clear variability in attributes such as degree of confidence in managing their asthma, use of reliever and preventer medication, and level of asthma control. CONCLUSIONS: The 5 patient clusters identified in this analysis displayed distinctly different personal attitudes that would require different approaches in the consultation room certainly for asthma but probably also for other chronic diseases. PMID- 29170005 TI - High heterogeneity, mixed infections and new genotypes in human congenital toxoplasmosis cases in the mega-metropolis of Central Mexico. AB - Mexico presents high prevalence of Toxoplasma gondii infection, including the congenital form, but there are few data about the genetic diversity of the parasite, so we attempted parasite isolation and genotyping in nine mother/children pairs with congenital toxoplasmosis (CT), living in the Valley of Mexico, who were part of a 30 cases cohort that started 12 years ago. They were recruited through research projects which included pre- and postnatal screening of congenital infections or directly CT, and cases referred to INP for management because they had clinical abnormalities. Genotyping was performed by PCR-RFLP of SAG1, SAG2, SAG3, BTUB GRA6, c22-8, c29-2, L358, PK1 and Apico markers, followed by sequencing. Sixty seven percent of samples were typed for the SAG3 locus, 39% for Apico and 33% for BTUB, while Alt. SAG2, GRA6 and c29-2 types could be labelled in less cases. Type I alleles predominated, followed by II and III. We isolated the first strain obtained from humans in Mexico and found three genotypes not previously found in the world. The presence of ToxoDB#10 clonal type was documented in one pair, as well as mixed infections in five mothers. No relation of genotype or parasite load with clinical signs was found. In conclusion, we encountered great genetic diversity and mixed T. gondii infections among mother/children pairs with congenital toxoplasmosis in the mega-metropolis of the Valley of Mexico. PMID- 29170006 TI - Intraneural cyst of the supraescapular nerve: Atypical cause of peripheral nerve entrapment syndrome. Case report and literature review. AB - OBJECTIVE: Intraneural cysts are benign lesions located within the epineurium of some peripheral nerves and their aetiopathogenesis is controversial. Most are located at the level of the lower limbs. In the upper limbs, the most frequently affected nerve is the ulnar nerve. Suprascapular nerve entrapment syndrome due to the formation of an intraneural cyst is rare. In this article, we show a new case and perform a literature review of intraneural cysts located in the suprascapular nerve. METHODS: We present a 49-year-old woman with pain in the lateral shoulder region of several months' evolution. A brachial plexus MR showed a tumour of approximately 2*1.5cm, with a cystic appearance, in relation to the upper trunk of the right brachial plexus. RESULTS: We used a supra-infraclavicular approach. The cystic tumour affected the suprascapular nerve. After locating a zone on the surface without nervous fascicles, we performed a partial resection of the capsule and emptying of the cyst, with a xanthochromic gelatinous content. The anatomopathological examination confirmed the diagnosis of intraneural cyst. CONCLUSION: The suprascapular nerve is a mixed nerve, coming from the upper trunk. It provides the motor branches to the supraspinatus and infraspinatus muscle. Compression of the suprascapular nerve leads to atrophy of these muscles. This entity is one of the differential diagnoses in a patient with pain irradiating to the shoulder, and its correct treatment often results in complete remission of symptoms. PMID- 29170007 TI - Capacitation in Plant and Animal Fertilization. AB - Sexual reproduction relies on the successful fusion of the sperm and egg cell. Despite the vast differences between plants and animals, there are similarities at a molecular level between plant and animal reproduction. While the molecular basis of fertilization has been extensively studied in plants, the process of capacitation has received little attention until recently. Recent research has started to uncover the molecular basis of plant capacitation. Furthermore, recent studies suggest that the key molecules in plants and animal fertilization are functionally conserved. Here, we review new insights for our understanding of capacitation of pollen tube and fertilization in plants and also propose that there are commonalities in the process of sexual reproduction between plants and animals. PMID- 29170008 TI - Genetic Control of Root System Development in Maize. AB - The maize root system comprises structurally and functionally different root types. Mutant analyses have revealed that root-type-specific genetic regulators intrinsically determine the maize root system architecture. Molecular cloning of these genes has demonstrated that key elements of auxin signal transduction, such as LOB domain (LBD) and Aux/IAA proteins, are instrumental for seminal, shoot borne, and lateral root initiation. Moreover, genetic analyses have demonstrated that genes related to exocytotic vesicle docking, cell wall loosening, and cellulose synthesis and organization control root hair elongation. The identification of upstream regulators, protein interaction partners, and downstream targets of these genes together with cell-type-specific transcriptome analyses have provided novel insights into the regulatory networks controlling root development and architecture in maize. PMID- 29170009 TI - Factors Associated with Inadequate Pain Control among Postoperative Patients with Cancer. AB - Postoperative pain is considered a major, complex and multidimensional problem that affects the clinical and functional outcomes of patients and may contribute to increased postoperative complications. The goal of this study was to determine the prevalence of inadequate pain control and to investigate the factors associated with inadequate pain control among postoperative cancer patients. A descriptive correlational, cross-sectional design was used. The study was conducted at four adult inpatient oncology departments at King Hussein Cancer Center, a nongovernmental, nonprofit, comprehensive hospital for treating cancer patients in Amman, Jordan. The convenience sample of 800 cancer patients selected comprised postoperative patients diagnosed with cancer and aged >=18 years who were willing to participate and able to use the numeric rating scale. About 32.9% of patients had pain scores higher than 4/10 at rest, and 56.4% of patients had pain scores higher than 4/10 on movement. Data revealed that patients aged between 18 and 63 years (odds ratio [OR] = 0.196, p < .0005, and OR = 0.245, p < .0005) and chronic user patients (OR = 28.029, p < .0005, and OR = 10.332, p < .0005) had increased odds of poor pain control at rest and on movement, respectively. Administration of preemptive medications and of fentanyl and bupivacaine during the postoperative period was significantly associated with decreased odds of poor pain control. The intravenous route was associated with increased odds of poor pain control at rest and on movement (OR = 2.279, p = .016, and OR = 5.393, p = .012) compared with other routes, including combinations of the intravenous and oral or epidural route. Chronic use of pain medications and older age were predictors of inadequate pain control postoperatively. Administration of preemptive medications and of combinations of fentanyl and bupivacaine via the epidural route was associated with better pain control. PMID- 29170010 TI - Elongator-a tRNA modifying complex that promotes efficient translational decoding. AB - Naturally occurring modifications of the nucleosides in the anticodon region of tRNAs influence their translational decoding properties. Uridines present at the wobble position in eukaryotic cytoplasmic tRNAs often contain a 5-carbamoylmethyl (ncm(5)) or 5-methoxycarbonylmethyl (mcm(5)) side-chain and sometimes also a 2 thio or 2'-O-methyl group. The first step in the formation of the ncm(5) and mcm(5) side-chains requires the conserved six-subunit Elongator complex. Although Elongator has been implicated in several different cellular processes, accumulating evidence suggests that its primary, and possibly only, cellular function is to promote modification of tRNAs.

AB - Studying melting and energetics of the DNA double helix has been one of the major topics of molecular biophysics over the past six decades. The main objective of this article is to overview the current state of the field and to emphasize that there are still serious gaps in our understanding of the issue. We start with a concise description of the commonly accepted theoretical model of the DNA melting. We then concentrate on studies devoted to the comparison with experiment of theoretically predicted melting profiles of DNAs with known sequences. For long DNA molecules, such comparison is significant from the basic-science viewpoint while an accurate theoretical description of melting of short duplexes is necessary for various very important applications in biotechnology. Several sets of DNA melting parameters, proposed within the framework of the nearest neighbor model, are compared and analyzed. The analysis leads to a conclusion that in case of long DNA molecules the consensus set of nearest neighbor parameters describes well the experimental melting profiles. Unexpectedly, for short DNA duplexes the same set of parameters hardly yields any improvement as compared to the simplest model, which completely ignores the effect of heterogeneous stacking. Possible causes of this striking observation are discussed. We then overview the issue of separation of base-pairing and base stacking contributions into the double helix stability. The recent experimental attempts to solve the problem are extensively analyzed. It is concluded that the double helix is essentially stabilized by stacking interaction between adjacent base pairs. Base pairing between complementary pairs does not appreciably contribute into the duplex stability. In the final section of the article, kinetic aspects of the DNA melting phenomenon are discussed. The main emphasis is made on the hysteresis effects often observed in melting of long DNA molecules. It is argued that the phenomenon can be well described via an accurate theoretical treatment of the random-walk model of melting kinetics of an isolated helical segment in DNA.

PMID- 29170013 TI - Evaluation of photosensitizer penetration into sound and decayed dentin: A photoacoustic spectroscopy study. AB - BACKGROUND: Photodynamic therapy (PDT) may have topical indications. In those cases it is important for a topical photosensitizer to penetrate into the tissue to which it has been applied. This study aimed to compare the penetration of two different concentrations of erythrosine into intact and in vitro decayed dentin samples. METHODS: This in vitro study evaluated erythrosine (0.3 and 5%) penetration into sound (intact) and decayed dentin. A total of 11 dentin discs were prepared and divided into two equal halves, in order to keep one half sound while the other half was submitted to sterilization and an in vitro demineralization model for 5 days. Before erythrosine application, the organic and inorganic composition of all samples was evaluated by Fourier Transform Raman spectroscopy, and after erythrosine application for 30 min, the penetration depth was determined by Photoacoustic spectroscopy technique. RESULTS: The results indicated that 0.3% erythrosine showed a higher penetration depth into sound dentin (p = 0.002); and 5% erythrosine higher penetration into decayed dentin (p < 0.001). However considering clinical parameters, no statistically significant difference was found between any of the conditions tested. CONCLUSIONS: Erythrosine demonstrated ability to penetrate into dentin, irrespective of sound or decayed condition. Photoacoustic spectroscopy can be considered a method for estimating the penetration into hard tissues, and in conjunction with Raman spectroscopy, these are effective methods for evaluating the spectral response of dentin. Considering that erythrosine is capable of penetrating into decayed dentin, clinical trials are needed to test the effectiveness of this photosensitizer in Photodynamic therapy and Antimicrobial Photodynamic therapy.

AB - PURPOSE: Review of various publications on stem cell therapy to treat erectile dysfunction of diabetic origin. MATERIAL AND METHODS: Bibliographic search in PUBMED performed using the keywords cell therapy strain/erectile dysfunction associated with diabetes. Among the 51 articles obtained from the PUBMED research, we selected 16 articles for their specificity of studying erectile dysfunction (DE) related to diabetes. RESULTS: Different types of stem cells have been studied: adipose derived mesenchymal stem cells/bone marrow derived mesenchymal stem cells as well as progenitor endothelial cells. The experimental protocols are quite similar from one study to the next with nevertheless some specifications concerning the studied cells and the monitoring of the latter. Intracavernous pressure (ICP) measured after the injection of stem cells into the corpus cavernosum was always significantly higher than the control populations. The addition of certain growth factors to stem cells by gene transfection improve the efficacy of the cells. No ideal tracking markers of the cells have been identified. CONCLUSION: The positive effect of the injection of stem cells on the ICP belongs to the cellular trans-differentiation effect but especially to the paracrine effects which have not yet been completely elucidated.

AB - CONTEXT: Detrusor sphincter disorders impact quality of life in case of deep endometriosis. Surgery, which is one of the main treatments, is responsible of detrusor sphincter disorders. Since then, it is essential to look for those disorders and find the right medical care. OBJECTIVE: To specify the detrusor sphincter disorders, its links with anatomical localisation of deep endometriosis and its prognosis after surgery. METHODS: A literature review was carried out via PubMed(r) with the followings keywords: "deep endometriosis", "urinary disorders", "voiding dysfunction" and "urinary dysfunction". Prospective and retrospective studies as well as previous reviews were analyzed. RESULTS: Concerning bladder deep endometriosis, detrusor sphincter disorders are observed in more than 50%. Resection of the lesions allows a clear improvement or even a disappearance of the disorders. Concerning the deep endometriosis of the posterior part of the pelvis, disorders are highlighted even if women do not complain of urinary trouble. Detrusor sphincter disorders are observed in 2 to 50% and women with colorectal localisation have the highest rate. Resection of the lesions improves the symptoms described preoperatively but also provides de novo disorders of up to 47.5%. In terms of prevention, the nerve sparing surgery respects the pelvic nerve plexus, and reduces post-operative morbidity to less than 1%. CONCLUSIONS: Detrusor sphincter disorders associated with deep endometriosis have a prognosis if their management is adapted. Well-conducted interviews and standardized questionnaires is necessary to diagnosis them. Urodynamic test may be discussed in case of bladder endometriosis, including for urinary asymptomatic patients. The management of the detrusor sphincter disorders requires a complete resection of the nodules of deep endometriosis. In the case of posterior endometriosis, a dissection must be performed respecting the retroperitoneal vegetative nerves.

AB - INTRODUCTION: The epidemiology of kidney cancer is evolving with a net increase in the incidence of renal tumors, globally, and in young people in particular. OBJECTIVE: To evaluate the incidence and clinical and pathological characteristics of sporadic renal tumors in young subjects and their risk factors. MATERIAL AND METHODS: A retrospective study aimed at collecting clinical, epidemiological and anatomopathological information from the 118 patients aged 18 to 40 treated for a sporadic kidney tumor in two Parisian university hospital centers between 2003 and 2013. RESULTS: Our study showed a very significant increase in the incidence of renal tumors in our 11 years of decline (P=6.10-15). The mode of discovery also seems to have evolved with a majority of tumors (67 %), due to the considerable growth of imaging in recent decades. We also showed a different pathological distribution compared to the literature with a significant increase in the number of papillary tumors (16.9 %) and chromophobes (15.2 %), in addition to a decrease in the number of carcinomas (43.2 %) as well as the appearance of a new pathological entity of particular clinical severity: renal carcinoma related to translocation Xp11.2 (15.3 %) (P<10 5). Among the risk factors, hypertension seems to be a definite risk factor while tobacco and obesity do not have a significant influence. CONCLUSION: Our study showed a marked increase in the incidence of renal tumors with specific clinical and epidemiological features in a population of young subjects. The role and importance of oncogenetic management as well as the study of environmental factors could lead to the identification of new risk factors and corollary to their prevention. LEVEL OF EVIDENCE: 4. PMID- 29170017 TI - Follicular large cleaved cell (centrocytic) lymphoma: an unrecognized variant of follicular lymphoma. AB - The World Health Organization classification of lymphoma recommends the subdivision of follicular lymphoma (FL) into 3 grades (FL1-3) based on the average number of centroblasts per high-power field in the neoplastic follicles, but does not recognize a form of FL characterized by a predominance of large cleaved cells (centrocytes) without enough centroblasts to meet the World Health Organization criteria for FL3. We have classified such cases as follicular large cleaved cell lymphoma (FLC) and, herein, describe the pathologic and clinical features of 72 cases of this entity. The features of FLC include a follicular growth pattern with pale follicles at low magnification and frequent follicular and/or interfollicular fibrosis. Cytologically, the cells are predominantly large cleaved cells with moderately coarse to fine chromatin, absent or inconspicuous nucleoli, and small to moderate amounts of pale cytoplasm. The mean nuclear diameter of the large cleaved cells was 10.1MU, approximately twice that of small lymphocytes and similar to centroblasts. The t(14;18) was present in 83% of the cases, and a high proportion expressed BCL2 (84%), BCL6 (100%), and CD10 (88%) and had high Ki67 proliferation (81%). The clinical features of patients with FLC were similar to those with other types of FL, and survival was excellent with anthracycline-based chemotherapy plus rituximab. FLC is a variant of follicular lymphoma which should be recognized in future lymphoma classifications because the diagnosis of FLC may be important for the selection of therapy. PMID- 29170018 TI - Ocular torsion responses to sinusoidal electrical vestibular stimulation. AB - BACKGROUND: Eye movements evoked by electrical vestibular stimulation (EVS) offer potential for diagnosing vestibular dysfunction. However, ocular recording techniques are often too invasive or impractical for routine clinical use. Furthermore, the kinematic nature of the EVS signal is not fully understood in terms of movement sensations. NEW METHOD: We apply sinusoidal EVS stimuli varying from 0.05 to 20Hz, and record the eye in darkness using an infrared camera. Eye movement was measured offline using commercially available software to track iris striations. Response gain and phase were calculated separately for eye position, velocity and acceleration across all frequencies, to determine how the brain interprets the EVS signal. RESULTS: Ocular torsion responses were observed at the same frequency as the stimulus, for all frequencies, while lateral/vertical responses were minimal or absent. Response gain and phase resembled previously reported responses to natural rotation, but only when analysing eye velocity, not position or acceleration. COMPARISON WITH EXISTING METHOD(S): Our method offers a simple, affordable, reliable and non-invasive method for tracking the ocular response to EVS. It is more convenient than scleral coil recordings, or marking the sclera to aid video tracking. It also allows us to assess the torsional VOR at frequencies not possible with natural stimuli. CONCLUSIONS: Ocular torsion responses to EVS can be readily assessed using sinusoidal stimuli combined with an infrared camera. Gain and phase analysis suggests that the central nervous system interprets the stimulus as head roll velocity. Future work will assess the diagnostic potential for patients with vestibular disorders. PMID- 29170019 TI - Evaluation of a rapid and sensitive RT-qPCR assay for the detection of Ebola Virus. AB - BACKGROUND: The 2013-2016 Ebola virus disease (EVD) outbreak showed a lack of diagnostic point-of-care methods. Currently, EBOV diagnosis relies on quantitative reverse-transcription-PCR (RT- qPCR), highly specific and sensitive, but requiring skilled personnel and well-equipped laboratories. In field settings, these factors and others, such as samples' time of collection and transportation, determine a prolonged turnaround-time to final results. In outbreak scenarios, a rapid and transportable method could eliminate issues of cohorting suspected and actual EVD patients for lack of diagnostic certainty. The aim of this study was the field evaluation of the new fast, easy-to-use and reliable RT-qPCR assay and platform for EBOV detection, developed in the framework of the EbolaMoDRAD project by CLONIT S.r.l. and STMicroelectronics S.r.l. STUDY DESIGN: We evaluated its performance during the outbreak and in further studies in the EVD laboratory at the Princess Christian Maternity Hospital (PCMH) in Freetown (Sierra Leone) run by Emergency NGO and the Italian National Institute for Infectious Diseases (INMI). The assay was tested on residual aliquots of clinical specimens from EBOV-positive or -negative patients (n=116, EVD prevalence 37%). RESULTS AND CONCLUSION: Overall, the test was very easy-to-use and the instrument was robust and reliable in field-settings. The sensitivity of the assay was 100% and the specificity was 98.63% (95%CI: 96.34 100.92%). The positive and negative predictive values were 97.73 (95%CI:94.77 100.68%) and 100%, respectively. The high sensitivity and specificity of this new assay indicate that it is promising for laboratory diagnosis, especially in resource-limited settings. PMID- 29170020 TI - Impact of Race on the Surgical Management of Adhesive Small Bowel Obstruction. AB - BACKGROUND: Small bowel obstruction (SBO) represents roughly 15% of admissions by general surgeons. Management of SBO relies heavily on provider judgment, including decisions on how long to try nonsurgical management and whether to use a laparoscopic or open approach when surgery is needed. Given the subjective nature of these decisions, it is unknown if patient race influences management of SBO. STUDY DESIGN: The National Surgical Quality Improvement Program was used to identify patients who underwent adhesiolysis or small bowel resection for adhesive SBO between 2010 and 2015 (n = 13,896). Adjusted logistic regression models incorporating patient comorbidity, American Society of Anesthesiologists (ASA) class, and emergency status were used to analyze odds of receiving surgery after 5 days from hospital admission (Eastern Association for the Surgery of Trauma guidelines) and of undergoing an open operation. RESULTS: Patients who waited more than 5 days for a procedure had greater adjusted odds of postoperative complication (odds ratio [OR] 1.56 95% CI 1.37 to 1.79) compared with those waiting 5 days or less. Similarly, open procedures had higher odds of complication compared with laparoscopic (OR 2.31 95% CI 2.00 to 2.68). Regression analysis demonstrated that black patients were significantly more likely than white patients to wait more than 5 days for surgery (OR 1.31 95% CI [1.13-1.53]) and undergo open surgery (OR 1.56, 95% CI 1.36 to 1.79). There was no statistical difference for Hispanics patients waiting more than 5 days (OR 0.98, 95% CI 0.73 to 1.31) or receiving open surgery (OR 0.84, 95% CI 0.70 to 1.01) compared with white patients. CONCLUSIONS: Clinical decisions regarding SBO management differ based on patient race. Future studies focusing on the surgical decision-making process and the influence of bias are needed. PMID- 29170021 TI - Chronic stress and the introduction to captivity: How wild house sparrows (Passer domesticus) adjust to laboratory conditions. AB - The conditions of captivity can cause chronic stress in wild animals. Newly captured animals may experience weight loss, elevated glucocorticoid hormones, increased heart rate, increased resting adrenomedullary activation, and an altered heart rate response to acute stressors. As captivity conditions persist, chronic stress may decrease as animals adjust to the stressors of captivity. In this study, house sparrows (Passer domesticus) were captured from the wild, fitted with heart rate transmitters in a minor surgical process, and individually housed in an indoor bird facility. Mass, baseline corticosterone, resting heart rate, resting adrenomedullary activation, and the acute heart rate response to a sudden noise were measured over the course of the first 6 weeks of captivity. Birds lost weight during the first weeks of captivity, which was regained by week 5. Baseline corticosterone peaked at day 7, decreased sharply by day 11, and continued to decrease throughout the 6 weeks. Although heart rate in the first 24 h could not be collected, daytime heart rate decreased from day 1 through day 20, where it reached a stable plateau. Daytime heart rate variability decreased through the entire 6 weeks, which may indicate a gradual shift from sympathetic to parasympathetic nervous system regulation of heart rate. The acute heart rate response to a sudden noise lasted longer at day 6 than earlier or later in captivity. In conclusion, the data indicate that the different physiological systems associated with chronic stress adjust to captivity over different timelines. PMID- 29170022 TI - Functional analysis of the promoter of the molt-inhibiting hormone (mih) gene in mud crab Scylla paramamosain. AB - In this study, the 5'-flanking region of molt-inhibiting hormone (MIH) gene was cloned by Tail-PCR. It is 2024 bp starting from the translation initiation site, and 1818 bp starting from the predicted transcription start site. Forecast analysis results by the bioinformatics software showed that the transcription start site is located at 207 bp upstream of the start codon ATG, and TATA box is located at 240 bp upstream of the start codon ATG. Potential transcription factor binding sites include Sp1, NF-1, Oct-1, Sox-2, RAP1, and so on. There are two CpG islands, located at -25- +183 bp and -1451- -1316 bp respectively. The transfection results of luciferase reporter constructs showed that the core promoter region was located in the fragment -308 bp to -26 bp. NF-kappaB and RAP1 were essential for mih basal transcriptional activity. There are three kinds of polymorphism CA in the 5'-flanking sequence, and they can influence mih promoter activity. These findings provide a genetic foundation of the further research of mih transcription regulation.

PMID- 29170024 TI - Exploiting a water network to achieve enthalpy-driven, bromodomain-selective BET inhibitors. AB - Within the last decade, the Bromodomain and Extra-Terminal domain family (BET) of proteins have emerged as promising drug targets in diverse clinical indications including oncology, auto-immune disease, heart failure, and male contraception. The BET family consists of four isoforms (BRD2, BRD3, BRD4, and BRDT/BRDT6) which are distinguished by the presence of two tandem bromodomains (BD1 and BD2) that independently recognize acetylated-lysine (KAc) residues and appear to have distinct biological roles. BET BD1 and BD2 bromodomains differ at five positions near the substrate binding pocket: the variation in the ZA channel induces different water networks nearby. We designed a set of congeneric 2- and 3 heteroaryl substituted tetrahydroquinolines (THQ) to differentially engage bound waters in the ZA channel with the goal of achieving bromodomain selectivity. SJ830599 (9) showed modest, but consistent, selectivity for BRD2-BD2. Using isothermal titration calorimetry, we showed that the binding of all THQ analogs in our study to either of the two bromodomains was enthalpy driven. Remarkably, the binding of 9 to BRD2-BD2 was marked by negative entropy and was entirely driven by enthalpy, consistent with significant restriction of conformational flexibility and/or engagement with bound waters. Co-crystallography studies confirmed that 9 did indeed stabilize a water-mediated hydrogen bond network. Finally, we report that 9 retained cytotoxicity against several pediatric cancer cell lines with EC50 values comparable to BET inhibitor (BETi) clinical candidates. PMID- 29170026 TI - Nose-to-brain peptide delivery - The potential of nanotechnology. AB - Nose-to-brain (N-to-B) delivery offers to protein and peptide drugs the possibility to reach the brain in a non-invasive way. This article is a comprehensive review of the state-of-the-art of this emerging peptide delivery route, as well as of the challenges associated to it. Emphasis is given on the potential of nanosized drug delivery carriers to enhance the direct N-to-B transport of protein or peptide drugs. In particular, polymer- and lipid- based nanocarriers are comparatively analyzed in terms of the influence of their physicochemical characteristics and composition on their in vivo fate and efficacy. The use of biorecognitive ligands and permeation enhancers in order to enhance their brain targeting efficiency is also discussed. The article concludes highlighting the early stage of this research field and its still unveiled potential. The final message is that more explicatory PK/PD studies are required in order to achieve the translation from preclinical to the clinical development phase. PMID- 29170025 TI - Design and synthesis of highly selective pyruvate dehydrogenase complex E1 inhibitors as bactericides. AB - In order to obtain PDHc-E1 inhibitors with high selectivity and efficacy, four series (7, 12, 15, and 19) of 35 novel 4-aminopyrimidine derivatives were rationally designed and synthesized based on the binding site of ThDP in E. coli PDHc-E1. 12, 15, and 19 were confirmed to be potent inhibitors against E. coli PDHc-E1. Selected compounds 12g, 12i, 15f, and 19a showed negligible inhibition against porcine PDHc-E1. To understand their selectivity, the interaction of inhibitor and E. coli PDHc-E1 or porcine PDHc-E1 was studied by molecular docking. The newly introduced acylhydrazone and N-phenylbenzamide moieties could form stronger interaction by hydrogen bond at the active site of E. coli PDHc-E1 compared with that of porcine PDHc-E1. A part of title compounds as potent PDHc E1 inhibitors also exhibited notable antibacterial activity. In particular, 12e, 12f, 12g, 12o, and 19a exhibited 72-92% inhibition against Xanthomonas oryzae pv. Oryzae and Ralstonia solanacearum at 100 MUg/mL, which was better than thiodiazole-copper (34 and 29%, respectively) and bismerthiazol (56 and 55%, respectively). The results proved that we could obtain effective bactericidal compounds as highly selective PDHc inhibitors by rational molecular design utilizing the binding model of active site of E. coli PDHc-E1. PMID- 29170027 TI - UVA irradiation of BrU-substituted DNA in the presence of Hoechst 33258. AB - Given that our knowledge of DNA repair is limited because of the complexity of the DNA system, a technique called UVA micro-irradiation has been developed that can be used to visualize the recruitment of DNA repair proteins at double-strand break (DSB) sites. Interestingly, Hoechst 33258 was used under micro-irradiation to sensitize 5-bromouracil (BrU)-labelled DNA, causing efficient DSBs. However, the molecular basis of DSB formation under UVA micro-irradiation remains unknown. Herein, we investigated the mechanism of DSB formation under UVA micro irradiation conditions. Our results suggest that the generation of a uracil-5-yl radical through electron transfer from Hoechst 33258 to BrU caused DNA cleavage preferentially at self-complementary 5'-AABrUBrU-3' sequences to induce DSB. We also investigated the DNA cleavage in the context of the nucleosome to gain a better understanding of UVA micro-irradiation in a cell-like model. We found that DNA cleavage occurred in both core and linker DNA regions although its efficiency reduced in core DNA. PMID- 29170028 TI - Identification of cytotoxic, glutathione-reactive moieties inducing accumulation of reactive oxygen species via glutathione depletion. AB - Reactive oxygen species (ROS) play an essential role in the survival and progression of cancer. Moderate oxidative stress drives proliferation, whereas high levels of ROS induce cytotoxicity. Compared to cancer cells, healthy cells often exhibit lower levels of oxidative stress. Elevation of cellular ROS levels by small molecules could therefore induce cancer-specific cytotoxicity. We have employed high-throughput phenotypic screening to identify inducers of ROS accumulation. We found 4,5-dihalo-2-methylpyridazin-3-one (DHMP) and 2,3,4,5(6) tetrachloro-6(5)-methylpyridine (TCMP) moieties to strongly deplete GSH, to cause ROS accumulation and to induce cell death. Small molecules containing these fragments will most likely share the same properties and should therefore be carefully considered in the development of bioactive molecules. PMID- 29170029 TI - Crucial but understudied: incentives in HIV research. PMID- 29170032 TI - Negative Valence Life Events Promote Breast Cancer Development. AB - BACKGROUND: The influence of stress on breast cancer risk remains unknown. The goal of the present study was to determine the effect of stress in the form of salient positive and negative valence life events (LEs) on primary invasive breast cancer risk. We hypothesized that salient negative LEs would increase breast cancer risk and salient positive LEs would attenuate this increased risk. PATIENTS AND METHODS: We used a case-control design with 664 cases identified through the Cancer Surveillance Program of Orange County and 203 population-based controls. Participants completed a risk factor questionnaire, which included a LE section. Fourteen salient LEs of positive or negative valence were used to quantify stress exposure. A baseline model was constructed, and odds ratios (ORs) were calculated using multivariate unconditional logistic regression. RESULTS: Negative LEs were associated with increased breast cancer risk. The OR for >= 4 negative LEs showed a 2.81-fold increase in breast cancer risk (OR, 2.81; 95% confidence interval [CI], 1.47-5.36). A significant dose-response relationship between lifetime negative valence LEs and breast cancer risk was found. Previous personal illness increased breast cancer risk by 3.6-fold (OR, 3.60; 95% CI, 2.50 5.20). In contrast, abortion was associated with a 45% decrease in breast cancer risk (OR, 0.55; 95% CI, 0.34-0.89). Salient positive LEs did not have a significant effect on breast cancer risk. However, they seemed to buffer the adverse effect of salient negative LEs on breast cancer risk. CONCLUSION: The findings from the present study support the role of salient negative LEs in promoting breast cancer development, with a possible buffering effect of salient positive LEs. PMID- 29170031 TI - Development of a new protein labeling system to map subunits and domains of macromolecular complexes for electron microscopy. AB - Several gene fusion technologies have been successfully applied to label particular subunits or domains within macromolecular complexes to enable positional mapping of electron microscopy (EM) density maps, but exogenous fusion of a protein domain into the target polypeptide can cause unwanted structural and functional outcomes. Fab fragments from antibodies can be used as labeling reagents during EM visualization without gene manipulation of the target protein, but this method requires a panel of high-affinity antibodies that recognize a wide variety of epitopes. Linear peptide tags and their anti-tag antibodies can be used but they have a limited mapping ability as their placement is usually limited to the terminal regions of a protein. The PA dodecapeptide epitope tag (GVAMPGAEDDVV), forms a tight beta-turn in the antigen binding pocket of its antibody (NZ-1). This capability allows for insertion of the PA tag into various surface-exposed loops within a multi-domain cell adhesion receptor, alphaIIbbeta3 integrin. We confirmed that the purified PA-tagged integrin ectodomain fragments can form a stable complex with NZ-1 Fab. Negative stain EM of the various integrin-NZ-1 complexes revealed that a majority of the particles exhibited a clear density corresponding to the NZ-1 Fab; and the positions of the bound Fab were in good agreement with the predicted location of the inserted PA tag. The high-affinity and insertion-compatibility of the PA tag system allowed us to develop a new EM labeling methodology applicable to proteins for which good antibodies are not available. PMID- 29170030 TI - Economic incentives for HIV testing by adolescents in Zimbabwe: a randomised controlled trial. AB - BACKGROUND: HIV testing is the important entry point for HIV care and prevention service, but uptake of HIV testing and thus coverage of antiretroviral therapy are much lower in older children and adolescents than in adults. We investigated the effect of economic incentives provided to caregivers of children aged 8-17 years on uptake of HIV testing and counselling in Harare, Zimbabwe. METHODS: This randomised controlled trial was nested within a household HIV prevalence survey of children aged 8-17 years in Harare. Households with one or more survey participants whose HIV status was unknown were eligible to participate in the trial. Eligible households were randomly assigned (1:1:1) to either receive no incentive, receive a fixed US$2 incentive, or participate in a lottery for $5 or $10 if the participant presented for HIV testing and counselling at a local primary health-care centre. The survey fieldworkers who enrolled participants were not blinded to trial arm allocation, but the statistician was blinded for analysis of outcome. The primary outcome was the proportion of households in which at least one child had an HIV test within 4 weeks of enrolment. HIV test uptake in the incentivised groups was compared with uptake in the non incentivised group using logistic regression, adjusting for community and number of children as fixed effects and research assistant as a random effect. All analyses were by intention to treat. The trial is registered with the Pan African Clinical Trials Registry, number PACTR201605001615280. FINDINGS: Between Aug 4, and Dec 18, 2015, 2050 eligible households were enrolled in the prevalence survey. 649 (32%) households were assigned no incentive, 740 (34%) households were assigned a $2 incentive, and 661 (32%) households were assigned to lottery participation. Children were unavailable in 148 households in the no-incentive group, 63 households in the $2 incentive group, and 81 households in the lottery group. 1688 households had at least one child with unknown HIV status and were enrolled into the trial. 22 households had no undiagnosed child, and one household refused consent. The primary outcome of HIV testing was assessed in 472 (28%) households in the no-incentive group, 654 (39%) households in the $2 incentive group, and 562 (33%) households in the lottery group. At least one child was HIV tested in 93 (20%) households in the no-incentive group, in 316 (48%) households in the $2 incentive group (adjusted odds ratio 3.67, 95% CI 2.77 4.85; p<0.0001), and in 223 (40%) of 562 households in the lottery group (2.66, 2.00-3.55; p<0.0001). No adverse events were reported. INTERPRETATION: Fixed incentives and lottery-based incentives increased the uptake of HIV testing by older children and adolescents, a key hard-to-reach population. This strategy would be sustainable in the context of vertical HIV infection as repeated testing would not be necessary until sexual debut. FUNDING: Wellcome Trust. PMID- 29170033 TI - 6-Hydroxydopamine induces autophagic flux dysfunction by impairing transcription factor EB activation and lysosomal function in dopaminergic neurons and SH-SY5Y cells. AB - Autophagy deregulation has been implicated in Parkinson's disease (PD), yet the role of autophagy in neuronal survival remains controversial. In this study, we comprehensively investigated the time-course of autophagy-related markers in 6 OHDA-induced Parkinsonian rat models and assessed its effect on the state of autophagic flux both in vivo and in vitro. We observed an early activation of autophagy followed by autophagic flux impairment, which was confirmed with autophagy inhibitor chloroquine in vivo and Ad-GFP-mCherry-LC3-infected SH-SY5Y cells in vitro. In addition, 6-OHDA not only remarkably reduced the expression level of lysosome-associated membrane protein 1 (Lamp1), but also impaired the hydrolase activities of lysosomal proteases. Transcription factor EB (TFEB), a key transcription factor controlling lysosome biogenesis, was also significantly downregulated by 6-OHDA and its nuclear translocation was inhibited as well, which could account for the impaired lysosomal function. Promoting lysosome biogenesis through TFEB overexpression could protect SH-SY5Y cells against 6-OHDA induced neurotoxicity. The above findings demonstrated that autophagic flux dysfunction was closely associated with 6-OHDA-induced neurotoxicity and highlighted the importance of functional lysosomes and homeostatic autophagic flux in developing therapeutic agents for PD. PMID- 29170034 TI - Bioequivalence of locally acting lozenges: Evaluation of critical in vivo parameters and first steps towards a bio-predictive in vitro test method. AB - Locally-acting lozenges are among the most common types of solid dosage forms applied in the oral cavity. Since no guidance on the in vitro demonstration of local bioequivalence is available, we wanted to develop a new bio-predictive test method for dissolution of lozenges based on a set of physiological parameters relevant to lozenge dissolution in the oral cavity. An in vivo sucking study determining the impact of different lozenge (candy) bases and flavours on sucking times, saliva osmolality and salivary flow rates was performed in 6 volunteers. In vivo sucking times were compared with in vitro dissolution times observed in experiments with official dissolution methods. In vitro dissolution times of all formulations were significantly longer than average in vivo sucking times (20-30 vs. <5 min) indicating that official test methods are not applicable for predicting in vivo dissolution of lozenges. Therefore, we developed and evaluated a novel test apparatus enabling the simulation of forces applied by tongue and hard palate during sucking. Results obtained in a first set of in vitro experiments came very close to those obtained in vivo. This novel in vitro approach is thus very promising in terms of predicting the bioequivalence of locally-acting lozenges.

AB - BACKGROUND: Oxygen supplementation for exercise-induced hypoxemia is a common clinical practice that improves exercise tolerance. However, we know of no standardized exercise oxygen titration protocol using a single walk test. We report our experience with a protocol developed in our laboratory. METHODS: Our protocol is based on the 6-min walk test (6MWT). Pulse oximetry readings (oxygen saturation [Spo2]) are monitored, and supplemental oxygen is added in 2 L/min increments to keep Spo2 > 88%. This continues for at least 6 min of walking with the Spo2 remaining > 88% for at least 3 min. The records of consecutive patients over 4 months undergoing this procedure were reviewed for test performance, oxygen titration results, and adverse events. RESULTS: Two hundred twenty-two patients were tested; only two prematurely terminated the protocol because of intractable dyspnea. One hundred fifty-six patients (38%) required oxygen supplementation, with the first titration most commonly occurring between 1 and 2 min of walking. Nine of the patients had the first titration after 5 min of walking. The average test duration was 7 min (maximum, 15 min). The average number of titrations was 2.2 (maximum six). Sixteen patients could not maintain Spo2 > 88% for 3 min despite administration of 15 L/min of supplemental oxygen (maximal dose). CONCLUSIONS: Our protocol was easily performed as a modification of a standard 6MWT with no serious adverse events. Because it is based on a widely accepted measurement of functional capabilities, and because it determined a stable final oxygen dose for >= 3 min of walking in most patients, we believe this protocol can be easily adapted for clinical use. PMID- 29170036 TI - Mucins, Mucus, and Goblet Cells. AB - The respiratory epithelium is lined by mucus, a gel consisting of water, ions, proteins, and macromolecules. The major macromolecular components of mucus are the mucin glycoproteins, which are critical for local defense of the airway. There are three classes of mucins in the airways: those that are secreted but do not polymerize (MUC7), those that are secreted and polymerize to form gels (MUC5AC, MUC5B), and those that have transmembrane domains and are cell surface associated (MUC1, MUC4, MUC16, MUC20). The mucins are regulated at the transcriptional, posttranscriptional, and epigenetic levels, and posttranslational modifications play an important role in mucin binding and clearance of microbes and pollutants. The development of mice deficient in specific mucins, and the cystic fibrosis pig, has greatly advanced our understanding of the role of mucins as innate immune mediators and how mucins and mucus contribute to lung disease. These observations suggest new strategies to ameliorate mucus obstruction by targeting mucociliary clearance and mucin hyperconcentration. Furthermore, a polymorphism in the promoter of MUC5B is strongly associated with risk of developing pulmonary fibrosis, supporting a novel function for MUC5B to influence interstitial lung disease. Exciting new data support the concept not only that mucins and mucus are important for lung homeostasis and protection from environmental threats but also that goblet cells play an important role as regulators of innate immune function. These insights into the innate immune properties of mucins and goblet cells support a shift from the current paradigm of repressing increased mucin expression to targeting regulation of specific mucins and the abnormal airway milieu. PMID- 29170037 TI - Stiff and tough: a comparative study on the tensile properties of shark skin. AB - In sharks, the skin is a biological composite with mineralized denticles embedded within a collagenous matrix. Swimming performance is enhanced by the dermal denticles on the skin, which have drag reducing properties produced by regional morphological variations and changes in density along the body. We used mechanical testing to quantify the effect of embedded mineralized denticles on the quasi-static tensile properties of shark skin to failure in four coastal species. We investigated regional differences in denticle density and skin properties by dissecting skin from the underlying fascia and muscle at 10 anatomical landmarks. Hourglass-shaped skin samples were extracted in the cranial to caudal orientation. Denticle density was quantified and varied significantly among both regions and species. We observed the greatest denticle densities in the cranial region of the body for the bonnethead, scalloped hammerhead, and bull sharks. Skin samples were then tested in tension until failure, stress strain curves were generated, and mechanical properties calculated. We found significant species and region effects for all three tensile mechanical properties. We report the greatest ultimate tensile strength, stiffness, and toughness near the cranial and lateral regions of the body for all 4 of the coastal species. We also report that denticle density increases with skin stiffness but decreases with toughness. PMID- 29170038 TI - Micromorphology of ovaries and oogenesis in Grania postclitellochaeta (Clitellata: Enchytraeidae). AB - The genus Grania comprises over 70 species of exclusively marine clitellate annelids belonging to the family Enchytraeidae. Morphologically, this genus is well separated from other enchytraeids, with thick cuticles, anterior segments I IV fused into a "head", chaetal bundles consisting only of one stout chaeta, and reduction of circular musculature. The aim of the present study is to describe the ovary organization and the course of oogenesis in Grania postclitellochaeta, and to compare it with other known systems of ovary organization and oogenesis in clitellate annelids, especially in enchytraeids. Generally, oogenesis in G. postclitellochaeta can be divided into two phases: (i) early stages of oogenesis, occurring within the paired ovaries - each ovary is similar to a bunch of grapes, where each 'lobe' is a germ-line cyst enveloped by flat somatic cells, and (ii) oogenesis proper, which takes place within the body lumen where each growing oocyte is accompanied by its own group of nurse cells. Germ cells are interconnected by cytoplasmic channels (intercellular bridges, ring canals) and form syncytial cysts. As in other clitellate annelids, the cyst center contains a common cytoplasm (cytophore) to which each cell is connected by one ring canal only. Initially, within the ovary, all interconnected cells develop synchronously and are morphologically similar. At the time when the cysts detach from the ovary, one of the interconnected cells begins to gather nutrients, grows and becomes an oocyte, whereas the rest of the cells (nurse cells) do not continue meiosis and instead seem to provide the oocyte with macromolecules and cell organelles. Analysis of serial sections reveals that cysts are always composed of 16 cells - one oocyte and fifteen nurse cells. A comparative analysis showed that almost all features of oogenesis in G. postclitellochaeta are similar to that in other representatives of Enchytraeidae (mainly Enchytraeus albidus), suggesting evolutionary conservation of the process across this family. PMID- 29170039 TI - [Delineation of the surgical bed of operated brain metastases treated with adjuvant stereotactic irradiation: A review]. AB - Stereotactic radiotherapy of the surgical bed of brain metastases is a technique that comes supplant indications of adjuvant whole brain radiotherapy after surgery. After a growing number of retrospective studies, a phase III trial has been presented and validated this indication. However, several criteria such as the dose, the fractionation, the use of a margin and definition of volumes remain to be defined. Our study consisted in making a literature review in order to provide a guideline of delineation of surgical beds of brain metastases, as well as the different modalities of their implementation process. PMID- 29170040 TI - Elevated production of IL-36alpha in chronic hepatitis B virus-infected patients correlates with viral load. AB - Chronic hepatitis B (CHB) infection is a typical inflammatory disease characterized by a dysregulated expression of cytokines, which contributes to the pathogenesis of chronic Hepatitis B virus (HBV) infection. IL-36 cytokines (IL 36alpha, IL-36beta, IL-36gamma and IL-36Ra) are important players in infection and immunity. However, their roles in the pathogenesis of chronic HBV infection remain unknown. Here the circulating concentrations of IL-36 cytokines from 50 CHB patients and 30 healthy controls were determined by enzyme-linked immunosorbent assay (ELISA). Sera concentrations of IL-36alpha were found to be significantly elevated in CHB patients, while the concentrations of IL-36beta, IL 36gamma and IL-36Ra were not significantly different in comparison to healthy donors. Furthermore, increased IL-36alpha concentrations correlated positively with HBV-DNA levels in CHB patients. Our study suggests that IL-36alpha production was up-regulated during CHB infection, which could be directly related to HBV-DNA loads in CHB patients. The immunoregulatory role of IL-36alpha in the pathogenesis of chronic HBV infection should be further studied. PMID- 29170041 TI - NFkappaB transcription factor (p65) immunohistochemistry in leprosy dermal microvasculature. AB - Leprosy caused by Mycobacterium leprae is characterized by a spectrum of clinical manifestations that are determined by the predominant immunological profile of the host. The recruitment of leukocytes to the sites of injury can influence the development of these profiles. Cell adhesion molecules such as ICAM-1, VCAM-1 and CD62E participate in this process and their expression is regulated by transcriptions factors such as NFkappaB. To correlate the expression of cell adhesion molecules and NFkappaB (p65) in leprosy lesions, 30 skin biopsies of patients with leprosy [16 with the tuberculoid (TT) or borderline tuberculoid (BT) forms and 14 with the lepromatous (LL) or borderline lepromatous (BL) forms] were analyzed by immunohistochemistry. A larger mean number of cells expressing VCAM-1 (BT/TT: 18.28 +/- 1.4; BL/LL: 10.67 +/- 1.2; p = 0.0002), ICAM-1 (BT/TT: 9.92 +/- 1.1; BL/LL: 5.87 +/- 1.0; p = 0.0084) and CD62E (BT/TT: 13.0 +/- 1.5; BL/LL: 2.58 +/- 0.3; p = 0.0001) were observed in BT and TT lesions. The mean number of cells expressing NFkappaB was similar in the two clinical forms (BT/TT: 2.21 +/- 2.7; BL/LL: 2.35 +/- 3.1;p = 0.9285). No significant correlation was observed between expression of the transcription factor and adhesion molecules analyzed. The synthesis of ICAM-1, VCAM-1 and CD62E depends on the activation of NFkappaB, which acts synergistically with other transcription factors. Adequate activation of intracellular signaling pathways results in the production of endothelial adhesion molecules, contributing to the recruitment of cells to the site of injury and thus eliciting an effective inflammatory response in the elimination of the bacillus. PMID- 29170042 TI - Anti-cancer effects of Staphylococcal Enterotoxin type B on U266 cells co cultured with Mesenchymal Stem Cells. AB - BACKGROUND: Malignant plasma cells are responsible for Multiple Myeloma (MM). Myeloma Cells (MCs) are located in Bone Marrow (BM) and are in contact with stromal cells. The BM-derived Mesenchymal Stem Cells (BM-MSCs) affect MCs biology through different mechanisms. Currently, Staphylococcal Enterotoxin B (SEB) has been introduced as an anti-tumor agent that is able to kill cancer cells. The present study examined the effects of SEB on MCs and MSCs as an anti-tumor substance. METHODS: U266 cells co-cultured on BM-MSCs and treated with SEB and cell viability was analyzed by MTT assay and flow cytometry. The expression levels of IKKb, IL-6, IL-10, and TGF-beta genes were evaluated by Real Time-PCR technique in U266 cells and BM-MSCs. RESULTS: Data showed that in the presence of SEB, BM-MSCs support U266 cells proliferation and survival. Moreover, SEB, BM MSCs and BM-MSCs Conditioned Medium (CM) up-regulated IL-6 and IL-10 expression in U266 cells. Additionally, U266 cells showed increased levels in IKKb expression in presence of SEB or BM-MSCs, while expression of IKKb in U266 cells was down-regulated in coexistence of SEB with BM-MSCs or SEB with CM. Also, TGF beta remained without any changes. DISCUSSION: All in all, SEB can be an appropriate candidate to decrease proliferation and survival rate of cancer cells and it can make noticeable alteration in expression of some genes in U266 cells and BM-MSCs. Further molecular studies are needed to identify the mechanism of action of SEB on U266 cells and BM-MSCs. PMID- 29170043 TI - Green synthesis of silver nano particles from Atalantia monophylla (L) Correa leaf extract, their antimicrobial activity and sensing capability of H2O2. AB - In the present study deals with the green synthesis of silver nano particles from methanolic leaf extracts of Atalantia monophylla. The synthesized nano-particles are characterized by UV-vis spectroscopy, PL, FTIR, XRD, SEM with EDAX and TEM. The nano-particles are indicated in absorption peak at 404 nm in the absorption spectrum. Further micro graphical analysis confirmed the average size was estimated about 35 nm and SEAD pattern authorized well crystalline materials. The FTIR studies help to confirm the functional group of synthesized silver nano particles. The XRD data shown the crystalline nature of nano particles and EDAX measurement indicates the purity of silver metal. The antimicrobial effect of silver nanoparticles was tested on pathogenic organisms using agar well diffusion method. Minimum inhibitory concentration (MIC) and Minimum bactericidal/fungicidal concentration (MBC/MFC) were also investigated in different concentrations of leaf extract. The results indicated that synthesized silver nano particle of A. monophylla leaf extract has the potential of antimicrobial activity against pathogenic microorganism. In addition, this is the first report on leaf synthesized silver nano particles of A. monophylla. The antimicrobial activity against pathogenic microorganisms and the ability to detect hydrogen peroxide using the silver nanoparticles were confirmed which would find applications in the development of new antimicrobial drugs and new biosensors to detect the presence of hydrogen peroxide in various samples respectively. PMID- 29170044 TI - Differential gene expression in Mycobacterium bovis challenged monocyte-derived macrophages of cattle. AB - A functional genomics approach was used to examine the immune response for transcriptional profiling of PBMC M. bovis infected cattle and healthy control cattle to stimulation with bovine tuberculin (purified protein derivative PPD-b). Total cellular RNA was extracted from non-challenged control and M. bovis challenged MDM for all animals at intervals of 6 h post-challenge, in response to in-vitro challenge with M. bovis (multiplicity of infection 2:1) and prepared for global gene expression analysis using the Agilent Bovine (V2) Gene Expression Microarray, 8 * 60 K. The pattern of expression of these genes in PPD bovine stimulated PBMC provides the first description of an M. bovis specific signature of infection that may provide insights into the molecular basis of the host response to infection. Analysis of these mapped reads showed 2450 genes (1291 up regulated and 1158 down regulated) 462 putative natural antisense transcripts (354 up-regulated and 108 down regulated) that were differentially expressed based on sense and antisense strand data, respectively (adjusted P-value <= 0.05). The results provided enrichment for genes involved top ten up regulated and down regulated panel of genes, including transcription factors proliferation of T and B lymphocytes. The highest differentially-expressed genes were associated to immune and inflammatory responses, immunity, differentiation, cell growth, apoptosis, cellular trafficking and regulation of lipolysis and thermogenesis. Microarray results were confirmed in infected cattle by RT qPCR to identify potential biomarkers TLR2, CD80, NFKB1, IL8, CXCL6 and ADORA3 of bovine tuberculosis. PMID- 29170045 TI - Astragalus polysaccharides inhibit avian infectious bronchitis virus infection by regulating viral replication. AB - The avian coronavirus causes infectious bronchitis (IB), which is one of the most serious diseases affecting the avian industry worldwide. However, there are no effective strategies for controlling the IB virus (IBV) at present. Therefore, development of novel antiviral treatment strategies is urgently required. As reported, astragalus polysaccharides (APS) have potential antiviral effects against several viruses; however, the antiviral effect of APS against IBV remains unclear. In this study, we explored whether APS had the potential to inhibit IBV infectionby utilizing several in vitro experimental approaches. To this end, the effect of APS on the replication of IBV was examined in chicken embryo kidney (CEK) cells. Viral titers were calculated by using the plaque formation assay, and the cytotoxicity of APS was tested by utilizing a Cell Counting Kit-8 assay. The expression of viral mRNA and cytokine (IL-1beta, IL-6, IL-8 and TNF-alpha) mRNA transcripts was determined by real-time quantitative RT-PCR(qRT-PCR). IBV titers in infected CEK cells treated with APS were significantly reduced in a dose-dependent manner, indicating that APS inhibited IBV replication in vitro. We also found that the decreased viral replication after APS treatment was associated with reduced mRNA levels of the cytokines IL-1B, IL-6, IL-8 and TNF alpha. In conclusion, these results suggest that APS exhibit antiviral activities against IBV and it may represent a potential therapeutic agent for inhibiting the replication of IBV. PMID- 29170046 TI - The Single von Willebrand factor C-domain protein (SVC) coding gene is not involved in the hymenoptaecin upregulation after Israeli acute paralysis virus (IAPV) injection in the bumblebee Bombus terrestris. AB - Within insects, inductions of antimicrobial peptides (AMPs) have been reported after different virus challenges. It is believed that this link is not directly induced by the virus itself, but rather indirectly induced by secondary effects of virus infection. Here we explored if direct sensing of the virus could trigger AMP expression. Recently, a cytokine-like molecule vago, a member of the Single von Willebrand factor C-domain (SVC) protein family, has been shown to be induced by virus infection in a Dicer-2 dependent manner. SVCs are also reported to be responsive in relation to multiple environmental challenges including bacterial infections and the nutritional status in the model species Drosophila melanogaster. Within the bumblebee Bombus terrestris only one SVC member has been identified and is proven to be involved in both the host antiviral defense and the basal expression of AMP genes, thereby it is a possible candidate linking virus infection and AMPs induction. Here we showed that the injection of Israeli acute paralysis virus (IAPV) resulted in a higher hymenoptaecin expression at 1dpi. This expression is IAPV specific as neither injection of slow bee paralysis virus (SBPV) nor random dsRNA results in a similar induction at 1dpi. We could not prove that hymenoptaecin expression after IAPV treatment was related to BtSVC, as a silencing experiment did not lower hymenoptaecin induction. This leaves indirect activation by secondary effects of IAPV infection as a mechanism of AMP genes induction, or that IAPV infection influences the AMP expression dynamics which is initially induced by non-virus related triggers. PMID- 29170047 TI - Caffeic acid-assisted cross-linking catalyzed by polyphenol oxidase decreases the allergenicity of ovalbumin in a Balb/c mouse model. AB - Ovalbumin (OVA) is the most abundant egg white protein, but is also a major egg allergen. Desensitization of OVA may be a good way to control an egg allergy. In this study, caffeic acid-assisted cross-linked OVA catalyzed by polyphenol oxidase (PPO) was prepared, the effect of cross-linking on the allergenicity of OVA was tested in a Balb/c mouse model. Mice were orally sensitized with OVA or cross-linked OVA using cholera toxin as adjuvant. Clinical signs of allergy, specific antibody levels, serum histamine levels, mast cell protease-1 (mMCP-1) concentrations, morphological structure of duodenum, and cytokines were determined after mice were challenged with OVA or cross-linked OVA. Both OVA and cross-linked OVA induced allergic diarrhea in Balb/c mice, however, histological symptoms of small intestine were much milder in mice fed with cross-linked OVA than in those fed with OVA. A tendency toward decreased allergen-specific IgE, IgG, IgG1 and IgG2a levels, as well as serum histamine and mMCP-1 concentration were observed in cross-linked OVA group, accompanied by an inhibition of IL-4, IL 5, IL-13 and IFN-gamma production in the stimulated spleen cell. It could be concluded that caffeic acid-assisted PPO-catalyzed cross-linking significantly reduced the potential allergenicity of OVA, but may not completely eliminate it. PMID- 29170048 TI - Neuroprotective effect of berberine against environmental heavy metals-induced neurotoxicity and Alzheimer's-like disease in rats. AB - Heavy metals are reported as neurodegenerative disorders progenitor. They play a role in the precipitation of abnormal beta-amyloid protein and hyper phosphorylated tau, the main hallmarks of Alzheimer's disease (AD). The present study aimed to validate the heavy metals-induced Alzheimer's-like disease in rats as an experimental model of AD and explore the therapeutic effect of berberine via tracking its effect on the oxidative stress-inflammatory pathway. Alzheimer's like disease was induced in rats orally by a mixture of aluminium, cadmium and fluoride for three months, followed by berberine treatment for another one month. Berberine significantly improved the cognitive behaviors in Morris water maze test and offered a protective effect against heavy metals-induced memory impairment. Docking results showed that berberine inhibited AChE, COX-2 and TACE. Matching with in silico study, berberine downregulated the AChE expression and inhibited its activity in the brain tissues. Also, it normalized the production of TNF- alpha, IL-12, IL-6 and IL-1beta. Moreover, it evoked the production of antioxidant Abeta40 and inhibited the formation of Abeta42, responsible for the aggregations of amyloid-beta plaques. Histopathological examination confirmed the neuroprotective effect of berberine. The present data advocate the possible beneficial effect of berberine as therapeutic modality for Alzheimer's disease via its antiinflammatory/antioxidant mechanism. PMID- 29170049 TI - Brachytherapy for conservative treatment of invasive penile carcinoma in older patients: Single institution experience. AB - BACKGROUND: No study has examined the possibility to perform an organ sparing strategy in older patients with penile carcinoma, and amputation is frequently proposed. We report our experience of interstitial brachytherapy for the conservative treatment of penile carcinoma confined to the glans in patients aged of 70years and more. METHODS: A total of 55 patients candidates to conservative brachytherapy were identified. Median age was 73.8years (range: 70-95years). Patients underwent a circumcision then 3-4weeks later, an interstitial brachytherapy was delivered, median dose of 65Gy (range 55-74Gy). Salvage surgery was discussed in patients with histological confirmation of residual/relapsed tumor. RESULTS: With median follow-up of 9.0years, eight patients (14.5%) experienced a relapse, including five patients with local relapse. Three patients with local relapse only underwent salvage penile surgery, including two partial glansectomies and one total penectomy, and were in second complete remission at last follow-up. Among 55 patients analyzed for late side effects, seven patients (13.0%) presented pain or ulceration, 12 (22.2%) experienced urethral or meatal stenosis requiring at least one dilatation, two patients (3.7%) experienced both ulcerations and urethral complication. Three patients (5.5%) needed partial glansectomy for focal necrosis. At five years, estimated overall survival rate was 74.5% (95%CI: 62.0-87.0%) and local relapse free rate was 91.0% (95%CI: 82.6 99.4%). CONCLUSION: Brachytherapy is feasible in selected older patients with penile carcinoma, with efficacy and toxicity rates comparable to that of other series in younger patients. PMID- 29170050 TI - Identification of a pyruvate-to-lactate signature in pancreatic intraductal papillary mucinous neoplasms. AB - OBJECTIVE: We used transcriptomic profiling and immunohistochemistry (IHC) to search for a functional imaging strategy to resolve common problems with morphological imaging of cystic neoplasms and benign cystic lesions of the pancreas. METHODS: Resected pancreatic cancer (n = 21) and normal pancreas were laser-capture micro-dissected, and transcripts were quantified by RNAseq. Functional imaging targets were validated at the protein level by IHC on a pancreatic adenocarcinoma tissue microarray and a newly created tissue microarray of resected intraductal papillary mucinous neoplasms (IPMNs) and IPMN-associated adenocarcinomas. RESULTS: Genes encoding proteins responsible for cellular import of pyruvate, export of lactate, and conversion of pyruvate to lactate were highly upregulated in pancreatic adenocarcinoma compared to normal pancreas. Strong expression of MCT4 and LDHA was observed by IHC in >90% of adenocarcinoma specimens. In IPMNs, the pyruvate-to-lactate signature was significantly elevated in high grade dysplasia (HGD) and IPMN-associated adenocarcinoma. Additionally, cores containing HGD and/or adenocarcinoma exhibited a higher number of peri lesional stromal cells and a significant increase in peri-lesional stromal cell staining of LDHA and MCT4. Interestingly, the pyruvate-to-lactate signature was significantly upregulated in cores containing only low grade dysplasia (LGD) from patients with histologically confirmed IPMN-associated adenocarcinoma versus LGD cores from patients with non-invasive IPMNs. CONCLUSION: Our results suggest prospective studies with hyperpolarized [1-13C]-pyruvate magnetic resonance spectroscopic imaging are warranted. If these IHC results translate to functional imaging findings, a positive pyruvate-to-lactate imaging signature might be a risk factor for invasion that would warrant resection of IPMNs in the absence of other worrisome features. PMID- 29170051 TI - Multicenter study of early pancreatic cancer in Japan. AB - BACKGROUND/OBJECTIVES: The diagnosis of early-stage pancreatic ductal adenocarcinoma (PDAC) is still challenging. We conducted a multicenter study to clarify the clinical features of early-stage PDAC in Japan. METHODS: We collected patients with stage 0 and stage I PDAC according to the sixth edition of the Japanese Classification of Pancreatic Carcinoma. We retrospectively analyzed the clinical profiles including opportunities for medical examination, imaging modalities and findings, methods of cytological diagnosis, and prognosis according to the stages at diagnosis. RESULTS: Two hundred cases with Stage 0 and stage I PDAC were reported from 14 institutions, which accounted for approximately 0.7% and 3% of all PDAC cases, respectively. Overall, 20% of the early-stage PDAC cases were symptomatic. Indirect imaging findings such as dilatation of the main pancreatic duct were useful to detect early-stage PDAC. In particular, local fatty changes may be specific to early-stage PDAC. For preoperative pathologic diagnosis, cytology during endoscopic retrograde cholangiopancreatography was more commonly applied than endoscopic ultrasound fine-needle aspiration. Although the overall prognosis was favorable, new PDAC lesions developed in the remnant pancreas in 11.5% cases. CONCLUSIONS: This multicenter study revealed several key points concerning the diagnosis and management of early-stage PDAC, including screening of asymptomatic cases, importance of indirect imaging findings, application of cytology during endoscopic retrograde cholangiopancreatography, and the risk of carcinogenesis in the remnant pancreas. PMID- 29170052 TI - Impact of age on survival of patients with pancreatic cancer after surgery: Analysis of SEER data. AB - BACKGROUND: To explore the impact of age on all-cause death and cancer-specific death in patients with pancreatic duct adenocarcinoma (PDAC) undergoing surgery. MATERIALS AND METHODS: Individuals with PDAC undergoing surgery between 2004 and 2013 (N = 11,138) were retrospectively studied from the Surveillance, Epidemiology, and End Results (SEER) cancer registry database. The impact of age on all-cause death and cancer-specific death was assessed using Cox regression model and competing risk model respectively. RESULTS: Multivariate Cox regression analysis indicated that the risks of all-cause death increased with age: hazard ratios (95% confidence interval, 95%CI) were 1.10 (1.04-1.17), 1.31 (1.23-1.38), 1.47 (1.35-1.61) for groups 61-70 years, 71-80 years, and >80 years, respectively, compared with <=60 years. Multivariate competing risk analysis indicated that the risk of cancer-specific death was similar between patients <=60 years and 61-70 years (subhazard ratio 0.93; 95% confidence interval 0.87 1.00), but decreased in patients 71-80 years (subhazard ratio 0.84; 95%CI 0.79 0.90) and >80 years (subhazard ratio 0.76; 95%CI 0.68-0.85). CONCLUSION: Age at diagnosis appeared to be an independent predictor of prognosis, with reverse impacts on all-cause death and cancer-specific death. PMID- 29170053 TI - A comparative study of pathophysiological alterations in scorpionism induced by Tityus serrulatus and Tityus bahiensis venoms. AB - Scorpionism is a relevant public health problem in several countries in tropical and subtropical regions. In Brazil, Tityus serrulatus sting can induce acute lung injury in part as a consequence of inflammation. Despite the occurrence of other scorpions of Tityus genus in Brazilian scorpiofauna, the knowledge regarding pulmonary alterations is related to T. serrulatus venom (Tsv). Here we studied, comparatively, the pathophysiological changes in the rat airways envenomed by Tsv or T. bahiensis venom (Tbv), since both scorpions are involved in human accidents but with severe envenomations occurring when victims are stung by T. serrulatus. After intravenous injection of the venoms (200 MUg/kg), both were able to induce Evans blue extravasation (in 30 min) into airways and increased protein extravasation into lungs at 4 and 24 h, but the magnitude of such events was higher in Tsv group. Hemorrhage (in 60 min) in the lungs was higher in Tbv group, while IL-1beta (at 1 h) and IL-6 (at 1 and 4 h) in lung homogenates were detected only in Tsv group. Four and 24 h after envenomation, myeloperoxidase activity in lung was equally augmented in the envenomed groups, as well as an increased in polymorphonuclear cell numbers in bronchoalveolar lavage fluid. At 4 h blood leukogram showed increased leukocyte values with the highest neutrophilia in Tsv group. The numbers of leukocytes and neutrophils remained higher than control at 24 h in Tsv and Tbv groups, and it was accompanied by lympho (envenomed groups) and monocytosis (Tsv group). In conclusion, although Tbv was capable of inducing acute lung injury and blood leukocyte mobilization, most of the evaluated parameters were more affected by the Tsv. These results could help to explain the pathophysiology of the scorpionism and the clinical data arguing toward the greatest severity associated with T. serrulatus stings. PMID- 29170054 TI - Local and systemic effects of BdipTX-I, a Lys-49 phospholipase A2 isolated from Bothrops diporus snake venom. AB - The present work aimed to isolate a basic phospholipase A2 (PLA2) from Bothrops diporus snake venom (BdV), evaluate and compare the myotoxic and oedema-inducing activities, as well as the systemic effects caused by both the isolated PLA2 and BdV on Swiss mice. A Lys-49 PLA2 (BdipTX-I) was obtained through two chromatographic steps: an ion-exchange and a reverse phase. The local (oedema and myotoxicity) and systemic (hepatic and renal functions) effects were then assessed for BdipTX-I and BdV. Results showed that the oedema-inducing activity was significant in all tested doses (5 and 20 MUg/paw) for both BdipTX-I and BdV. Myotoxicity was evaluated by the increase of serum CK, CK-MB and LDH, and results showed that BdV effect is more prominent than BdipTX-I effect. The systemic effects were evaluated by determining specific laboratory markers: AST, ALT, GGT, ALP, urea, creatinine, protein and calcium. BdipTX-I and BdV were able to induce renal changes in the experimental model, leading to proteinuria (induced both by BdipTX-I and by BdV) and uremia (induced only by BdV). Thus, it is concluded that the systemic effects of BdV and BdipTX-I occur differently. PMID- 29170055 TI - Immune drug discovery from venoms. AB - This review catalogues recent advances in knowledge on venoms as standalone therapeutic agents or as blueprints for drug design, with an emphasis on venom derived compounds that affects the immune system. We discuss venoms and venom derived compounds that affect total immune cell numbers, immune cell proliferation, immune cell migration, immune cell phenotype and cytokine secretion. Identifying novel compounds that 'tune' the system, up-regulating the immune response during infectious disease and cancer and down-regulating the immune response during autoimmunity, will greatly expand the tool kit of human immunotherapeutics. Targeting these pathways may also open therapeutic options that alleviate symptoms of envenomation. Finally, combining recent advances in venomics with progress in low cost, high-throughput screening platforms will no doubt yield hundreds of prototype immune modulating compounds in the coming years.

AB - OBJECTIVE: Evaluate whether participation in Choose Health: Food, Fun, and Fitness (CHFFF), a hands-on, experiential curriculum aimed at third- to sixth graders, resulted in improvements in the targeted obesity and chronic disease prevention behaviors. METHODS: The researchers evaluated CHFFF in low-income youth participating in 2 federal programs in New York State during 2013-2015. Food and activity behaviors were assessed using the Expanded Food and Nutrition Education Program third- through fifth- and sixth- through eighth-grade pre-post surveys, along with 2 sets of added CHFFF-specific items completed by subsamples. Educators trained in CHFFF had youth complete the surveys as they delivered the curriculum, primarily in schools and after-school programs. RESULTS: Paired t tests showed significant (P < .01) positive changes before to after CHFFF education for consumption of vegetables, fruits, sweetened drinks, nutrition label reading, and other food and activity behaviors. CONCLUSIONS AND IMPLICATIONS: Results provide practice-based evidence that CHFFF promotes positive behavior change in participating youth.

AB - OBJECTIVE: To identify perceived barriers and enablers to implementation of dietary guidelines reported by early childhood education center cooks, and barriers and enablers associated with greater implementation based on assessment of center menu compliance. DESIGN: Cross-sectional telephone interview. SETTING: Early childhood education centers, New South Wales, Australia. PARTICIPANTS: A total of 202 cooks responsible for menu planning; 70 centers provided a menu for review of compliance with dietary guidelines. MAIN OUTCOME MEASURE: Barriers and enablers to dietary guideline implementation were determined using a tool assessing constructs of the Theoretical Domains Framework (TDF). Higher scores (>=6) for each construct indicated enablers to guideline implementation; lower scores (<6) suggested barriers. ANALYSIS: Multivariable linear regression identified TDF constructs associated with greater guideline implementation. RESULTS: Scores were lowest for reinforcement (mean, 5.85) and goals (mean, 5.89) domains, and highest for beliefs about consequences (mean, 6.51) and social/professional role and identity (mean, 6.50). The skills domain was positively associated with greater implementation of guidelines based on menu review (P = .01). CONCLUSIONS AND IMPLICATIONS: Cooks perceived social/professional role and identity, and beliefs about consequences to be enablers to dietary guideline implementation; however, only the skills domain was associated with greater implementation. There are opportunities to target the incongruence in perceptions vs reality of the barriers and enablers to implementation. Future research could examine the utility of the TDF to identify barriers and enablers to implementation to inform intervention development and for evaluating interventions to examine intervention mechanisms. PMID- 29170058 TI - Ability to Categorize Food Predicts Hypothetical Food Choices in Head Start Preschoolers. AB - OBJECTIVE: To investigate whether preschoolers are able to identify and categorize foods, and whether their ability to classify food as healthy predicts their hypothetical food choice. DESIGN: Structured interviews and body measurements with preschoolers, and teacher reports of classroom performance. SETTING: Six Head Start centers in a large southeastern region. PARTICIPANTS: A total of 235 preschoolers (mean age [SD], 4.73 [0.63] years; 45.4% girls). INTERVENTION(S): Teachers implemented a nutrition education intervention across the 2014-2015 school year in which children were taught to identify and categorize food as sometimes (ie, unhealthy) and anytime (ie, healthy). MAIN OUTCOME MEASURES: Preschooler responses to a hypothetical snack naming, classifying, and selection scenario. ANALYSIS: Hierarchical regression analyses to examine predictors of child hypothetical food selection. RESULTS: While controlling for child characteristics and cognitive functioning, preschoolers who were better at categorizing food as healthy or unhealthy were more likely to say they would choose the healthy food. Low-contrast food pairs in which food had to be classified based on multiple dimensions were outside the cognitive abilities of the preschoolers. CONCLUSIONS AND IMPLICATIONS: Nutrition interventions may be more effective in helping children make healthy food choices if developmental limitations in preschoolers' abilities to categorize food is addressed in their curriculum. Classification of food into evaluative categories is challenging for this age group. Categorizing on multiple dimensions is difficult, and dichotomous labeling of food as good or bad is not always accurate in directing children toward making food choices. Future research could evaluate further preschoolers' developmental potential for food categorization and nutrition decision making and consider factors that influence healthy food choices at both snack and mealtime. PMID- 29170059 TI - The clinical potential of adipogenesis and obesity-related microRNAs. AB - Obesity is a growing health problem commonly associated with numerous metabolic disorders including type 2 diabetes, hypertension, cardiovascular disease, and some forms of cancer. The burden of obesity and associated cardiometabolic diseases are believed to arise through complex interplay between genetics and epigenetics predisposition, nutrition, environment, and lifestyle. However, the molecular basis and the repertoire of obesity-affecting factors are still unknown. Emerging evidence is connecting microRNAs (miRNAs) dysregulation with adipogenesis and obesity. Alteration in miRNAs expression could result in changes in the pattern of genes controlling a range of biological processes including inflammation, lipid metabolism, insulin resistance and adipogenesis. Hence, understanding exact roles of miRNAs as well as the degree of their contribution to the regulation of adipogenesis and fat cell development in obesity would provide new therapeutic targets for the development of novel and effective anti obesity drugs. The objective of the current review is to: (i) discuss some of the latest development on relevant miRNAs dysregulation mainly in human adipogenesis and obesity, (ii) emphasize the role of circulating miRNAs as new promising therapeutics and attractive potential biomarkers for treating obesity and associated risk factor diseases, (iii) describe how dietary factors may influence obesity through modulation of miRNAs expression, (iv) highlight some of the actual limitations to the promise of miRNAs as novel therapeutics as well as to their translation for the benefit of patients, and finally (v) provide recommendations for future research on miRNA-based therapeutics that could lead to a breakthrough in the treatment of obesity and its associated pathologies. PMID- 29170060 TI - Low vitamin D status in relation to cardiovascular disease and mortality in Swedish women - Effect of extended follow-up. AB - BACKGROUND AND AIMS: The impact of vitamin D concentrations on subsequent cardiovascular disease (CVD) and overall mortality has been generally examined for periods under two decades. The magnitude of the association may depend on follow-up length. We aimed to investigate the relationship between baseline vitamin D and risk of total CVD, stroke and all-cause mortality over three decades of follow-up. Secondly, we aimed to assess how follow-up affects the associations. METHODS AND RESULTS: Concentrations of 25-hydroxyvitamin D (25D) were measured in a population-based sample of 1227 middle-aged women using serum collected at baseline and categorized into low (lowest 25D quartile) vs high 25D status (upper three 25D quartiles). Hazard ratio (HR) of the endpoints was estimated for low 25D. The impact of follow-up was examined in intermediary analyses where follow-up was interrupted up to four times, each time decreasing it by five years. There were 596 cardiovascular events and 635 participants died. During the first 17 years, the low 25D group experienced a 29% higher CVD risk and 3.3-fold higher stroke risk after accounting for confounders. Longer follow up diminished significantly these risks and 25D status had no contribution at 32 years. For mortality, the decline over time was less dramatic, with HR = 1.96 (1.25; 3.08) at 17 years and HR = 1.42 (1.17; 1.72) at 37 years. CONCLUSION: Low 25D status increased the risk for all endpoints, but a lengthy follow-up diminished these risks towards the null. The impact of follow-up depends on the outcome. Future studies of 25D and disease should use repeated 25D assessments. PMID- 29170061 TI - The association between muscle mass deficits and arterial stiffness in middle aged men. AB - BACKGROUND AND AIMS: Early diagnosis of arteriosclerosis is fundamental for the prevention of cardiovascular morbidity and mortality. The current study was performed to identify major predictors of arteriosclerosis and to assess the association between arterial stiffness as measured by cardio-ankle vascular index (CAVI) and muscle mass deficit (MMD) estimated by bioelectrical impedance analysis (BIA) in middle-aged men. METHODS AND RESULTS: Data were gathered from 3356 middle-aged men who visited a health promotion center. CAVI was measured as an index of arterial stiffness. Body composition analysis was performed using BIA. MMD was positively associated with CAVI in the regression model. The odds ratios for high-CAVI (>=9.0) rose with MMD grade in a dose-dependent manner after adjusting for age, lifestyle factors and current medication use. The estimated mean CAVI rose as MMD grade increased (P for trend >0.001). CONCLUSIONS: MMD estimated from BIA was positively associated with arterial stiffness in middle aged men. These findings show a close interaction between low muscle mass and cardiovascular risk. PMID- 29170062 TI - The relationship between high-density lipoprotein cholesterol levels and arterial stiffness in a Taiwanese population. AB - BACKGROUND AND AIMS: There are few studies on the association between HDL-C levels and arterial stiffness (AS). HDL-C levels vary in males and females, and it is not clear whether the relationship between HDL-C levels and AS is influenced by gender. The purpose of this study was to investigate gender differences in the association between HDL-C levels and AS in adults. METHODS AND RESULTS: After excluding subjects using lipid-lowering agent, 7254 subjects were enrolled. The AS was assessed by measuring the brachial-ankle pulse wave velocity (baPWV) value. The quartiles of HDL-C were <38, 38-45, 45-53 and >53 mg/dL in men and <48, 48-57, 57-69 and >68 mg/dL in women, respectively. In subjects aged <50 years, none of the HDL-C quartiles were associated with baPWV values. In subjects aged >=50 years, the highest quartile of HDL-C (beta: -37.57, 95% CI: -61.61 to 13.54) was negatively related to baPWV values. When considering gender difference in subjects aged >=50 years, the highest quartile of HDL-C (Q4 beta: -57.22, 95% CI: -95.63 to -18.81) was inversely associated with baPWV values in women, but none of the HDL-C quartiles were related to baPWV values in men. CONCLUSIONS: A high HDL-C level was associated with a lower risk of AS in subjects aged >=50 years in women but not in men, although this relationship was not apparent in subjects aged <50 years. The association between HDL-C level and AS is thus influenced by gender in people aged >=50 years. PMID- 29170064 TI - The role of paraoxonase in cancer. AB - The paraoxonase (PON) gene family includes three proteins, PON1, PON2 and PON3. PON1 and PON3 are both associated with high-density lipoprotein (HDL) particles and exert anti-oxidant and anti-inflammatory properties. PON2 and PON3 are intracellular enzymes which modulate mitochondrial superoxide anion production and endoplasmic reticulum (ER) stress-induced apoptosis. The pleiotropic roles exerted by PONs have been mainly investigated in cardiovascular and neurodegenerative diseases. In recent years, overexpression of PON2 and PON3 has been observed in cancer cells and it has been proposed that both enzymes could be involved in tumor survival and stress resistance. Moreover, a lower activity of serum PON1 has been reported in cancer patients. This review summarizes literature data on the role of PONs in human cancers and their potential role as a target for antitumor drugs. PMID- 29170063 TI - Incidence and progression of Parvovirus B19 infection and molecular changes in circulating B19V strains in children with haematological malignancy: A follow up study. AB - The present study was planned to estimate the incidence of human Parvovirus B19 infection and understand its progression in children suffering with hematological malignancy. The circulating B19V genotypes and viral mutations occurring in strains of B19V over one-year period were also studied. Children with malignancies were enrolled consecutively and were followed up for one-year period. Serum sample was collected at the time of enrolment and each follow up visit and was tested for anti B19V IgG and IgM as well as for B19V DNA. At least one B19V DNA positive sample from each patient was processed for sequencing. For patients positive for B19V DNA >1 time and at least 6 months apart, last positive sample from the same patient was also sequenced to study the nucleotide change over time. We have found very high incidence of B19V infection (100%) in the study population. All the patients tested positive for at least one B19V infection parameter (either antibodies or DNA) at least once, over one year of follow up. Cumulative percent positivity of anti B19V IgG, anti B19V IgM and B19V DNA was 85.3%, 45.2% and 72.1% respectively. Genotype 3b was reported, with occasional nucleotide change over one year period. DNA clearance was delayed in spite of appearance of IgG antibodies. Appearance of IgM class of antibodies was either delayed or absent. To conclude, children with haematological malignancies have high incidence of B19V infection with late and short lived serological response and persistence of DNA for long duration. PMID- 29170065 TI - Challenges in Ras therapeutics in pancreatic cancer. AB - Pancreatic cancer is considered among the most aggressive and the least curable of all human malignancies. It is usually characterized by multiple aberrations in tumor suppressor genes and oncogenes, most notably activating mutations in KRAS. This review examines the various attempts that have been made to inhibit Kras and its downstream signaling pathways in pancreatic cancer with an emphasis on challenges related to clinical trials. Attempts include preventing the localization of Ras protein to the plasma membrane, inhibiting downstream oncogenic signaling by targeting Kras effectors such as MEK1/2, Erk1/2 or Akt singly or in combination, and directly inhibiting Kras protein. Most clinical trials have focused on inhibiting downstream effector pathways and clinical benefit has been limited due to compensatory mechanisms and toxicity associated with small therapeutic windows. Additionally, genetic screens have been conducted to identify gene or genes that could provide therapeutic vulnerabilities in mutant KRAS cells and provide a way to target mutant Kras protein only. We also discuss how potentially transforming clinical trials have failed in the past and what new strategies are on-going in clinical trials for pancreas cancer. For long term success in targeting Kras, future efforts should focus on combinatorial strategies to more effectively block Kras pathways at multiple points, and improve translational application of pre-clinical data to the clinic. PMID- 29170066 TI - Glioma epigenetics: From subclassification to novel treatment options. AB - Gliomas are the most common malignant primary brain tumors, of which glioblastoma is the most malignant form (WHO grade IV), and notorious for treatment resistance. Over the last decade mutations in epigenetic regulator genes have been identified as key drivers of subtypes of gliomas with distinct clinical features. Most characteristic are mutations in IDH1 or IDH2 in lower grade gliomas, and histone 3 mutations in pediatric high grade gliomas that are also associated with characteristic DNA methylation patterns. Furthermore, in adult glioblastoma patients epigenetic silencing of the DNA repair gene MGMT by promoter methylation is predictive for benefit from alkylating agent therapy. These epigenetic alterations are used as biomarkers and play a central role for classification of gliomas (WHO 2016) and treatment decisions. Here we review the pivotal role of epigenetic alterations in the etiology and biology of gliomas. We summarize the complex interactions between "driver" mutations, DNA methylation, histone post-translational modifications, and overall chromatin organization, and how they inform current efforts of testing epigenetic compounds and combinations in preclinical and clinical studies. PMID- 29170067 TI - Perspectives on the integration of Immuno-Oncology Biomarkers and drugs in a Health Care setting. AB - Immunotherapies, specifically checkpoint inhibitors, are becoming an important component in cancer care with the most application now in melanoma and lung cancer patients. Some drawbacks that converge with this new evolution are the rather low response rates to these drugs and their high cost with a significant economic impact on the health care system. These major challenges can likely be circumvented by implementing a "personalized immuno-oncology" approach to accomplish a selection of optimal responders based on biomarkers. In this paper we first discuss the legal framework for the development of valuable in vitro diagnostics. Based on a case study in lung cancer, the clinical validity and utility requirements of predictive immuno-oncology biomarkers is highlighted and an overview is given on the evolution towards multiplex or omics-based assays together with its challenges and pitfalls. Finally, some initiatives between the public and private sector are pinpointed to sustain the future access to innovative medicines in cancer therapy at a reasonable cost. PMID- 29170068 TI - Enhanced heat tolerance in transgenic silkworm via overexpression of Pyrococcus furiosus superoxide reductase. AB - Heat shock causes a serious harm to organisms by accelerating the production of reactive oxygen species (ROS). Pyrococcus furiosus superoxide reductase (PfSOR) is an enzyme that efficiently detoxifies ROS. In order to generate a silkworm strain with high heat tolerance for sericulture, we synthesized an artificial DNA sequence encoding PfSOR based on the codon bias of Bombyx mori. PfSOR was successfully overexpressed in transgenic silkworm (named A4SOR) and BmE cells, as determined by RT-PCR and western blot analyses. An SOR activity assay confirmed that the expressed enzyme was functional in A4SOR. After exposure to a temperature of 35 degrees C for 44 h, the mortality rate was about 30% lower in transgenic A4SOR than in non-transgenic silkworms. Moreover, transgene expression had no apparent effect on economic characteristics of silkworms. The heat tolerance of silkworm was thus enhanced by expressing an archaeal SOR; this can be useful for sericulture in regions where the average temperature exceeds the optimal environmental temperature for B. mori of 25 degrees C. PMID- 29170070 TI - Dynamic phase alignment of ongoing auditory cortex oscillations. AB - Neural oscillations can synchronize to external rhythmic stimuli, as for example in speech and music. While previous studies have mainly focused on elucidating the fundamental concept of neural entrainment, less is known about the time course of entrainment. In this human electroencephalography (EEG) study, we unravel the temporal evolution of neural entrainment by contrasting short and long periods of rhythmic stimulation. Listeners had to detect short silent gaps that were systematically distributed with respect to the phase of a 3 Hz frequency-modulated tone. We found that gap detection performance was modulated by the stimulus stream with a consistent stimulus phase across participants for short and long stimulation. Electrophysiological analysis confirmed neural entrainment effects at 3 Hz and the 6 Hz harmonic for both short and long stimulation lengths. 3 Hz source level analysis revealed that longer stimulation resulted in a phase shift of a participant's neural phase relative to the stimulus phase. Phase coupling increased over the first second of stimulation, but no effects for phase coupling strength were observed over time. The dynamic evolution of phase alignment suggests that the brain attunes to external rhythmic stimulation by adapting the brain's internal representation of incoming environmental stimuli. PMID- 29170069 TI - A common neural network differentially mediates direct and social fear learning. AB - Across species, fears often spread between individuals through social learning. Yet, little is known about the neural and computational mechanisms underlying social learning. Addressing this question, we compared social and direct (Pavlovian) fear learning showing that they showed indistinguishable behavioral effects, and involved the same cross-modal (self/other) aversive learning network, centered on the amygdala, the anterior insula (AI), and the anterior cingulate cortex (ACC). Crucially, the information flow within this network differed between social and direct fear learning. Dynamic causal modeling combined with reinforcement learning modeling revealed that the amygdala and AI provided input to this network during direct and social learning, respectively. Furthermore, the AI gated learning signals based on surprise (associability), which were conveyed to the ACC, in both learning modalities. Our findings provide insights into the mechanisms underlying social fear learning, with implications for understanding common psychological dysfunctions, such as phobias and other anxiety disorders. PMID- 29170071 TI - Cortical networks for auditory detection with and without informational masking: Task effects and implications for conscious perception. AB - Ambiguous and masked stimuli have been used to study conscious perception by comparing neural activity during different percepts of identical physical stimuli. One limitation of this approach is that it typically requires a reporting task that may engage neural processes beyond those required for conscious perception. Here, we explored potential fMRI correlates of auditory conscious perception with and without overt report. In experiment 1, regular tone patterns were presented as targets under informational masking, and participants reported their percepts on each trial. In experiment 2, regular tone patterns were presented without masking, while the uninformed participants (i) passively fixated, (ii) performed an orthogonal visual task, and (iii) reported trial-wise the presence of the auditory pattern as in experiment 1 (in fixed order). Under informational masking, target-pattern detection was associated with activity in auditory cortex, superior temporal sulcus, and a distributed fronto-parieto insular network. Unmasked and task-irrelevant tone patterns elicited activity that overlapped with the network observed under informational masking in auditory cortex, the right superior temporal sulcus, and the ventral precentral sulcus in an ROI analysis. We therefore consider these structures candidate regions for a neural substrate of auditory conscious perception. In contrast, activity in the intraparietal sulcus, insula, and dorsal precentral sulcus were only observed for unmasked tone patterns when they were task relevant. These areas therefore appear more closely related to task performance or top-down attention rather than auditory conscious perception, per se.

AB - Exocrine pancreatic insufficiency (EPI) is one of the possible mechanisms of fat maldigestion following gastric surgery, together with reduced food intake, loss of gastric reservoir, small bowel bacterial overgrowth and rapid small bowel transit. Oral pancreatic enzyme replacement therapy (PERT) is the mainstay of treatment for EPI. The efficacy and safety of pancreatic enzyme substitution in patients following gastric resection remains unclear. This review article summarizes relevant studies addressing PERT after gastric resection. PMID- 29170073 TI - Effect of intravenous fentanyl on ticagrelor absorption and platelet inhibition among patients undergoing percutaneous coronary intervention: Design, rationale, and sample characteristics of the PACIFY randomized trial. AB - INTRODUCTION: Morphine reduces and delays the absorption of oral P2Y12 platelet inhibitors. Fentanyl is another opiate often administered during percutaneous coronary interventions (PCI). The PACIFY study will test whether intravenous fentanyl also impairs the absorption and action of oral P2Y12 inhibitors. METHODS: PACIFY is a single-center trial randomizing adults undergoing clinically indicated coronary angiography to have the procedure with or without fentanyl. All patients will receive local anesthetic and intravenous midazolam. Doses of all drugs are at the discretion of treating providers. Patients that require PCI receive 180mg of oral ticagrelor during the angiography procedure. The primary outcome is area under the ticagrelor plasma concentration-time curve. Secondary outcomes include platelet inhibition 2-h after loading, measured both by VerifyNow(r) (Accriva Diagnostics, San Diego, California) and by light transmission platelet aggregometry. We will also survey patient comfort and measure high-sensitivity troponin levels. Patients and outcomes assessors are blinded, treating providers are not. RESULTS: A total of 212 patients are participating, 70 of whom required PCI. Baseline characteristics are numerically well balanced in both study arms. Mean age is 63years and 27% are female. There were no differences in total midazolam dose during the index PCI procedure, whereas mean total fentanyl dose was 9 mcg in the no-fentanyl arm (2 participants in this arm required fentanyl for bailout treatment of pain) versus 96 mcg in the fentanyl arm. CONCLUSIONS: This study will provide important information on the impact of fentanyl administered during PCI on the absorption of ticagrelor and its antiplatelet activity. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT02683707. PMID- 29170074 TI - Study design considerations for the Standardized Treatment of Pulmonary Exacerbations 2 (STOP2): A trial to compare intravenous antibiotic treatment durations in CF. AB - BACKGROUND: Pulmonary exacerbations (PEx) in cystic fibrosis (CF) are common and contribute to morbidity and mortality. Duration of IV antibiotic therapy to treat PEx varies widely in the US, and there are few data to guide treatment decisions. METHODS: We combined a survey of CF stakeholders with retrospective analyses of a recent observational study of CF PEx to design a multicenter, randomized, prospective study comparing the efficacy and safety of different durations of IV antibiotics for PEx to meet the needs of people with CF and their caregivers. RESULTS: IV antibiotic duration was cited as the most important PEx research question by responding CF physicians and top concern among surveyed CF patients/caregivers. During PEx, forced expiratory volume in 1s (FEV1% predicted) and symptom responses at 7-10days of IV antibiotics identified two distinct groups: early robust responders (ERR) who subsequently experienced greater FEV1 improvements compared to non-ERR (NERR). In addition to greater FEV1 and symptom responses, only 14% of ERR patients were treated with IV antibiotics for >15days, compared with 45% of NERR patients. CONCLUSIONS: A divergent trial design that evaluates subjects' interim improvement in FEV1 and symptoms to tailor randomization to IV treatment duration (10 vs. 14days for ERR, 14 vs. 21days for NERR) may alleviate physician and patient concerns about excess or inadequate treatment. Such a study has the potential to provide evidence necessary to standardize IV antibiotic duration in CF PEx care -a first step to conducting PEx research of other treatment features. PMID- 29170075 TI - Reducing depressive symptoms through behavioral activation in churches: A Hybrid 2 randomized effectiveness-implementation design. AB - : Rural African Americans are disproportionately exposed to numerous stressors such as poverty that place them at risk for experiencing elevated levels of depressive symptoms. Effective treatments for decreasing depressive symptoms exist, but rural African Americans often fail to receive adequate and timely care. Churches have been used to address physical health outcomes in rural African American communities, but few have focused primarily on addressing mental health outcomes. Our partnership, consisting of faith community leaders and academic researchers, adapted an evidence-based behavioral activation intervention for use with rural African American churches. This 8-session intervention was adapted to include faith-based themes, Scripture, and other aspects of the rural African American faith culture (e.g. bible studies) This manuscript describes a Hybrid-II implementation trial that seeks to test the effectiveness of the culturally adapted evidence-based intervention (Renewed and Empowered for the Journey to Overcome in Christ: REJOICE) and gather preliminary data on the strategies necessary to support the successful implementation of this intervention in 24 rural African American churches. This study employs a randomized one-way crossover cluster design to assess effectiveness in reducing depressive symptoms and gather preliminary data regarding implementation outcomes, specifically fidelity, associated with 2 implementation strategies: training only and training+coaching calls. This project has the potential to generate knowledge that will lead to improvements in the provision of mental health interventions within the rural African American community. Further, the use of the Hybrid-II design has the potential to advance our understanding of strategies that will support the implementation of and sustainability of mental health interventions within rural African American faith communities. TRIAL REGISTRATION: NCT02860741. Registered August 5, 2016. PMID- 29170076 TI - Association of interleukin-6 with aortic stiffness in end-stage renal disease. AB - Cardiovascular disease (CVD) is the leading cause of mortality in patients with chronic kidney disease (CKD). Aortic stiffness, a nontraditional risk factor, is associated with high rate of mortality in CKD. Using a CKD animal model with medial vascular calcification, we previously reported increased mRNA expression of interleukin-6 (IL-6), tumor necrosis factor (TNF), and interleukin-1beta (IL 1beta) in calcified aorta. The aim of the study was to investigate the association between IL-6, TNF, IL-1beta, and aortic stiffness in end-stage renal disease patients. In a cross-sectional study, we enrolled 351 patients on dialysis. Aortic stiffness was assessed by carotid-femoral pulse wave velocity (cf-PWV), while central pulse pressure and augmentation index were assessed using generalized transfer function applied to the radial artery pressure wave form. Plasma IL-6, TNF, and IL-1beta were measured by enzyme-linked immunosorbent assay. IL-6 was associated with cf-PWV adjusted for mean blood pressure (MBP) (standardized beta = 0.270; P < .001). In a multivariate adjusted model for age, diabetes, hypertension, CVD, and MBP, IL-6 was still associated with cf-PWV (standardized beta = 0.096; P = .026). The impact of age, diabetes, and CVD on cf PWV was partially mediated by IL-6 in a mediation analysis. However, there were no associations between TNF, IL-1beta, and aortic stiffness. While IL-6 was associated with augmentation index (standardized beta = 0.224; P < .001) and central pulse pressure (standardized beta = 0.162; P = .001) when adjusted for MBP and heart rate, this relationship was not significant after adjusting for potential confounders.This study suggests a potential role of IL-6 for CKD related aortic stiffness. PMID- 29170077 TI - 5 years after introduction of a transition protocol: An evaluation of transition care for patients with chronic bladder conditions. AB - INTRODUCTION: In recent years, more attention has been given to the transition of adolescents in urological care. In 2010, the current team investigated the needs of children with chronic bladder conditions, in preparation for transfer to adult care. A transition protocol was developed and implemented. The current study evaluated current transition care, in order to further improve the transition process. OBJECTIVE: To give insight into the current transition care of adolescents with chronic bladder conditions since the introduction of a transition protocol in 2011. STUDY DESIGN: A total of 124 patients with chronic bladder conditions, born 1980-2003, received a questionnaire. The study population was divided in a pre-transfer (n = 97) and post-transfer group (n = 27). The questionnaire was based on that used for a national study and was supplemented with specific urological questions. The questions for the pre transfer patients investigated their level of independence, what subjects were discussed with the healthcare professionals, and their expectations and wishes regarding transfer to adult urology care. The post-transfer group was asked for their opinions about their transfer process. RESULTS: A total of 61% (n = 76/124) responded (pre-transfer 61/97 patients and post-transfer 1527 patients). Their knowledge about their condition and related issues was generally good. The subjects 'future', 'relationships', 'sexuality' and 'fertility' were discussed more with the nurse practitioner than with the pediatric urologist in comparison with 2010. The last three subjects were only discussed with one third of the adolescents (Summary table). The bond with the pediatric urologist was the most common reason to continue care at the Pediatric Urology department. Adolescents aged >18 years were better prepared for transfer to adult urology than in 2010. The majority of the post-transfer patients were transferred because of being aged >17 years. Most patients in the post-transfer group were pleased with the current transition process. DISCUSSION: The results showed that changes occurred after implementation of the personal patient transition protocol. The mean age of the pre-transfer group was younger compared to 2010; this influenced some of the results. Therefore, they were divided into two age groups, for more reliable outcomes. More attention to subjects like relationships and sexuality could further improve the satisfaction of adolescents in transition. CONCLUSION: The older adolescents seemed better prepared for their transfer from pediatric to adult urology than in 2010. The majority was satisfied with the current transition protocol. Tailor-made transition care seemed to be the best option. PMID- 29170078 TI - How common is substantial weight gain after pregnancy? AB - BACKGROUND: Although population-based studies indicate that on average, women gain 1-2kg between pregnancies, women with obesity often attribute its development to childbearing. There is little contemporary data available regarding how commonly this occurs, particularly in women of different body mass index (BMI) categories. The aim of this study was to examine inter-pregnancy weight changes among women at a tertiary obstetric hospital in Melbourne, Australia. METHODS: This was a retrospective review of data from the Birthing Outcomes System electronic record of 19,617 women aged 20 years or older, who delivered at least two consecutive singleton infants at >=37 weeks' gestation at Mercy Hospital for Women between December 1994 and December 2015. A logistic regression model was used to assess the relationship between gain of >=4kg/m2 between pregnancies and maternal BMI category in the first pregnancy, adjusting for covariates of maternal age, inter-pregnancy interval, and socioeconomic status. RESULTS: Gain of >=4kg/m2 between the first two pregnancies occurred in 7.5% of normal weight women, 10.5% of overweight women, and 13.4% of women with obesity. One in five women who were normal weight in their first pregnancy increased to overweight or obese BMI categories in their second pregnancy. CONCLUSIONS: Substantial weight gain in relation to pregnancy affects a considerable proportion of women. Since inter-pregnancy weight gain is associated with several complications in the next pregnancy and longer term, avoiding excessive weight gain during and between pregnancies may prevent adverse health consequences in mothers and offspring. PMID- 29170079 TI - Practical management of behavioral problems in mucopolysaccharidoses disorders. AB - The mucopolysaccharidosis (MPS) disorders are caused by deficiencies of specific lysosomal enzymes, resulting in progressive glycosaminoglycan (GAG) accumulation in cells and tissues throughout the body. Excessive GAG storage can lead to a variety of somatic manifestations as well as primary and secondary neurological symptoms. Behavioral problems (like hyperactivity, attention difficulties, and severe frustration) and sleeping problems are typical primary neurological symptoms of MPS caused by GAG accumulation in neurons, and are frequently observed in patients with MPS I, II, III, and VII. As these problems often place a significant burden on the family, proper management is important. This review summarizes current insights into behavioral and sleeping problems in MPS disorders and the most optimal management approaches, as presented and discussed during a meeting of an international group of experts with extensive experience in managing and treating MPS. PMID- 29170080 TI - Epilepsy in mucopolysaccharidosis disorders. AB - The mucopolysaccharidosis (MPS) disorders are caused by deficiencies of specific lysosomal enzymes involved in the catabolism of glycosaminoglycans (GAGs). The resulting GAG accumulation in cells and tissues throughout the body leads to progressive multi-organ dysfunction. MPS patients present with several somatic manifestations, including short stature, musculoskeletal abnormalities, and cardiorespiratory dysfunction, and several primary and secondary neurological signs and symptoms. Epileptic seizures are neurological signs of MPS thought to develop due to accumulation of GAGs in the brain, triggering alterations in neuronal connectivity and signaling, and release of inflammatory mediators. The amount of literature on the prevalence, pathophysiology, clinical features, and management of epileptic seizures in patients with MPS is limited. This review discusses current knowledge on this topic, as well as two case examples, presented and discussed during a closed meeting on MPS and the brain among an international group of experts with extensive experience in managing and treating MPS.

AB - BACKGROUND AND AIM: We previously reported a novel tumor associated antigen (TTA) with molecular weight around 48kDa that is a fragment derived from human DNA topoiomerase I (TOP1). We termed the novel TAA as TOPO48 and termed autoantibody against the TAA as anti-TOPO48 autoantibody. The aim of this study is to further investigate the clinical applications of the autoantibody in patients with esophageal squamous cell carcinomas (ESCC). METHODS: Serum levels of the anti TOPO48 autoantibody in 112 ESCC patients, 112 age- and gender-matched healthy controls and 75 patients with esophageal benign tumors were determined by using a specific anti-TOPO48 autoantibody ELISA. Then, we statistically evaluated its clinical significance. RESULTS: We found that serum anti-TOPO48 autoantibody levels in ESCC patients were significantly higher than that in healthy controls and benign tumor patients (P=0.001). The percentage of sera with a positive level of anti-TOPO48 autoantibody in early stages was significantly higher than that in advanced stages of the cancer patients when the maximum level of healthy control sera was taken as a cut-off value (P=0.001). The area under ROC curve was 0.863 (95% CI=0.797-0.928) for healthy controls vs. early stage ESCC. In addition, patients with positive anti-TOPO48 autoantibody had significantly higher survival rate and longer survival time than that with negative anti-TOPO48 autoantibody in cancer patients (P=0.038, 0.025 and 0.047 for all stages, early stage and advanced stage, respectively). CONCLUSIONS: Our results suggest that anti-TOPO48 autoantibody may be a potentially useful biomarker for early diagnosis and prognosis of ESCC.

AB - The trehalose-6-phosphate phosphatase (TPP) enzyme is involved in the synthesis of trehalose, the main sugar in the energy metabolism of nematodes. TPP is a member of the HAD-like hydrolase superfamily and shows a robust and specific phosphatase activity for the substrate trehalose-6-phosphate. The presence of conserved active sites of TPP in closely related nematodes and its absence in humans makes it a promising target for antiparasitic drugs. In the present study, homology modeling, molecular docking and MD simulation techniques were used to explore the structure and dynamics of TPP. In the active site, a magnesium ion is stabilized by 3 coordinate bonds formed by D189, D191 and D400. The key amino acids involved in ligand binding by the enzyme are C198, Y201,T357, D191 and Y197. This study relied on docking to select potential inhibitors of TPP which were tested in vitro for sensitivity to anthelmintic drugs such as levamisole and ivermectin targeting Anisakis simplex. The higher toxicity of LEV than IVM was demonstrated after 96 h, 30% of larvae were motile in cultures with 100 MUg/ml of LEV and 1000 MUg/ml of IVM. We identified drug combination of LEV-IVM against in vitro A. simplex as agonistic effect (CI = 1.1). Levamisole appeared to be a more effective drug which inhibited enzyme activity after 48 h and expression of mRNA after 96 h at a concentration of 10 MUg/ml. This preliminary study predicted the structure of TPP, and the results of an in vitro experiment involving A. simplex will contribute to the development of effective inhibitors with potential antiparasitic activity in the future. PMID- 29170086 TI - Toxoplasma gondii-positive human sera recognise intracellular tachyzoites and bradyzoites with diverse patterns of immunoreactivity. AB - Antibody detection assays have long been the first line test to confirm infection with the zoonotic parasite Toxoplasma gondii. However, challenges exist with serological diagnosis, especially distinguishing between acute, latent and reactivation disease states. The sensitivity and specificity of serological tests might be improved by testing for antibodies against parasite antigens other than those typically found on the parasite surface during the acute stage. To this end, we analysed the reactivity profile of human sera, identified as positive for anti-Toxoplasma gondii IgG in traditional assays, by indirect immunofluorescence reactivity to acute stage intracellular tachyzoites and in vitro-induced latent stage bradyzoites. The majority of anti-Toxoplasma gondii IgG positive sera recognised both intracellularly replicating tachyzoites and in vitro-induced bradyzoites with varying patterns of immune-reactivity. Furthermore, anti bradyzoite antibodies were not detected in sera that were IgM-positive/IgG negative. These results demonstrate that anti-Toxoplasma gondii-positive sera may contain antibodies to a variety of antigens in addition to those traditionally used in serological tests, and suggest the need for further investigations into the utility of anti-bradyzoite-specific antibodies to aid in diagnosis of Toxoplasma gondii infection. PMID- 29170087 TI - Avian malaria infection intensity influences mosquito feeding patterns. AB - Pathogen-induced host phenotypic changes are widespread phenomena that can dramatically influence host-vector interactions. Enhanced vector attraction to infected hosts has been reported in a variety of host-pathogen systems, and has given rise to the parasite manipulation hypothesis whereby pathogens may adaptively modify host phenotypes to increase transmission from host to host. However, host phenotypic changes do not always favour the transmission of pathogens, as random host choice, reduced host attractiveness and even host avoidance after infection have also been reported. Thus, the effects of hosts' parasitic infections on vector feeding behaviour and on the likelihood of parasite transmission remain unclear. Here, we experimentally tested how host infection status and infection intensity with avian Plasmodium affect mosquito feeding patterns in house sparrows (Passer domesticus). In separate experiments, mosquitoes were allowed to bite pairs containing (i) one infected and one uninfected bird and (ii) two infected birds, one of which treated with the antimalarial drug, primaquine. We found that mosquitoes fed randomly when exposed to both infected and uninfected birds. However, when mosquitoes were exposed only to infected individuals, they preferred to bite the non-treated birds. These results suggest that the malarial parasite load rather than the infection itself plays a key role in mosquito attraction. Our findings partially support the parasite manipulation hypothesis, which probably operates via a reduction in defensive behaviour, and highlights the importance of considering parasite load in studies on host-vector-pathogen interactions. PMID- 29170088 TI - Simplified medical abortion screening: a demonstration project. AB - OBJECTIVES: The objectives were to evaluate the safety and acceptability of outpatient medical abortion in selected women without a pretreatment ultrasound or pelvic examination. STUDY DESIGN: We conducted a prospective case-series study to estimate the incidence of serious adverse events (death, life-threatening event, hospitalization, transfusion or any other medical problem that we judged to be significant), surgical completion of the abortion and satisfaction in women provided with medical abortion without a pretreatment ultrasound or pelvic examination. We enrolled 406 women requesting medical abortion in Moldova, Mexico and the United States. To be eligible, a woman must have been certain that her last menstrual period started within the prior 56days, have had regular menses before the pregnancy, not have used hormonal contraceptives in the prior 2months (in the United States and Mexico) or 3months (in Moldova), have no risk factors for or symptoms of ectopic pregnancy, and not have had an ultrasound or pelvic exam in this pregnancy. One site also excluded women with uterine enlargement on abdominal palpation. Each participant received mifepristone (200mg orally) and misoprostol (400 mcg sublingually in Moldova; 800 mcg buccally at all other sites) and was followed until complete abortion, defined as requiring no further treatment. RESULTS: Of the 365 (90%) participants who provided sufficient follow up information for analysis, 347 (95%) had complete abortion without additional treatment, 5 (1%) had surgical aspiration, and 10 (3%) had extra misoprostol. Three participants (1%) had serious adverse events; these included two hospital admissions for heavy bleeding managed with aspiration and one diagnosis of persistent gestational sac 19days after enrollment. Most (317, 90%) participants were pleased with omitting the pretreatment ultrasound and pelvic exam. CONCLUSIONS: In this study, medical abortion without screening ultrasound or pelvic exam resulted in no serious adverse events that were likely to have been prevented by those tests and was highly acceptable. IMPLICATIONS: Screening for medical abortion without exam or ultrasound shows promise as a means for increasing access to this service. More research is needed to develop screening criteria that are more inclusive and simpler for clinical use. PMID- 29170089 TI - Schistosomiasis in the first 1000 days. AB - Infections during the first 1000 days-the period from conception to a child's second birthday-can have lifelong effects on health, because this is a crucial phase of growth and development. There is increasing recognition of the burden and potential effects of schistosomiasis in women of reproductive age and young children. Exposure to schistosomes during pregnancy can modulate infant immune development and schistosomiasis can occur from early infancy, such that the high disease burden found in adolescents is often due to accumulation of infections with long-lived schistosomes from early life. Women of reproductive age and young children are largely neglected in mass drug administration programmes, but early treatment could avert subsequent disease. We evaluate the evidence that early schistosomiasis has adverse effects on birth, growth, and development. We also discuss the case for expanding public health interventions for schistosomiasis in women of reproductive age and preschool-age children, and the need for further research to evaluate the potential of treating women pre-conception to maximise health across the life course. PMID- 29170090 TI - Mucolipidosis type III gamma: Three novel mutation and genotype-phenotype study in eleven patients. AB - Mucolipidosis type III gamma (MLIII gamma) is a lysosomal storage disease characterized by joint stiffness, mild coarse face and corneal clouding, which becomes recognizable usually in childhood. Biallelic mutations in the GNPTG gene, which encode the gamma subunit of the N-acetylglucosamine-1-phosphotransferase enzyme, are the underlying cause of MLIII gamma. The aim of this study is to evaluate the longitudinal findings and genotype of eleven patients from eight families with MLIII gamma and to establish a genotype-phenotype correlation. The most frequently observed initial finding was stiffness of finger joints, which detected in patients between 18month-olds and five year-olds. However, in four patients presented here, initial finding was knee pain or waddling gait, which started between six-16years of age. All patients also had variable degrees of stiffness on large joints. The longest follow up period was 16years while the shortest was three years and six months. We observed that the patients who had an early onset disease and severe joint stiffness had also rapidly progressive joint involvement mostly localized in hands, shoulders, and hip. However; the patients with late onset and/or mild joint stiffness experienced slowly progressive symptoms. Most patients dropped in their growth curve in time and the ones who were severely affected reached the final height below the third centile. Seven disease-causing mutations, three of them novel, were detected in GNPTG gene. According to our clinical observations c.493_494insC and c.283_284insC mutations lead to a severe phenotype and c.196C>T, c.347_349del, c.652_655delTACT and c.445delG/c.367A>G mutations seemed to generate a milder phenotype. PMID- 29170091 TI - Potentiation of glutathione loss and nerve cell death by the transition metals iron and copper: Implications for age-related neurodegenerative diseases. AB - There is growing evidence for alterations in iron and copper homeostasis during aging that are exacerbated in neurodegenerative diseases such as Alzheimer's disease (AD). However, how iron and copper accumulation leads to nerve cell damage in AD is not clear. In order to better understand how iron and copper can contribute to nerve cell death, a simple, well-defined in vitro model of cell death, the oyxtosis assay, was used. This assay uses glutamate to induce glutathione (GSH) depletion which initiates a form of oxidative stress-induced programmed cell death. A reduction in GSH is seen in the aging brain, is associated with cognitive dysfunction and is accelerated in many CNS diseases including AD. It is shown that both iron and copper potentiate both GSH loss and cell death in this model. Iron and copper also potentiate cell death induced by other GSH depleters but not by compounds that induce oxidative stress via other pathways. At least part of the effects of copper on GSH are related to its ability to reduce the activity of glutamate cysteine ligase, the rate limiting enzyme in GSH synthesis. Both metals also alter several signaling pathways involved in modulating nerve cell death. Together, these results suggest that in vivo iron and copper may specifically enhance nerve cell death under conditions where GSH levels are reduced.

PMID- 29170094 TI - The Choline Acetyltransferase (CHAT) Gene is Associated with Parahippocampal and Hippocampal Structure and Short-term Memory Span. AB - The CHAT gene encodes choline acetyltransferase, which is an enzyme responsible for the biosynthesis of the neurotransmitter acetylcholine in the brain. This study collected structural MRI, genetic, and behavioral data from 324 healthy Chinese adults, and examined the associations between CHAT genetic variants, parahippocampal and hippocampal structure, and short-term memory span. After controlling for intracranial volume, sex, and age, CHAT SNP rs12246528 had the strongest association with parahippocampal structure, with the A allele being linked to smaller volume, surface area, and thickness. SNP rs1917814 had the strongest association with hippocampal volume, with the T allele being linked to larger hippocampal volume. After controlling for sex and age, CHAT rs3729496 had the strongest association with memory span, with the T allele being associated with a greater memory span. Finally, the left parahippocampal gyrus surface area was positively associated with memory span. This study provides the first evidence for the involvement of the CHAT gene in parahippocampal and hippocampal structures and memory span in healthy Chinese adults. PMID- 29170092 TI - KRIT1 loss-of-function induces a chronic Nrf2-mediated adaptive homeostasis that sensitizes cells to oxidative stress: Implication for Cerebral Cavernous Malformation disease. AB - KRIT1 (CCM1) is a disease gene responsible for Cerebral Cavernous Malformations (CCM), a major cerebrovascular disease of proven genetic origin affecting 0.3 0.5% of the population. Previously, we demonstrated that KRIT1 loss-of-function is associated with altered redox homeostasis and abnormal activation of the redox sensitive transcription factor c-Jun, which collectively result in pro-oxidative, pro-inflammatory and pro-angiogenic effects, suggesting a novel pathogenic mechanism for CCM disease and raising the possibility that KRIT1 loss-of-function exerts pleiotropic effects on multiple redox-sensitive mechanisms. To address this possibility, we investigated major redox-sensitive pathways and enzymatic systems that play critical roles in fundamental cytoprotective mechanisms of adaptive responses to oxidative stress, including the master Nrf2 antioxidant defense pathway and its downstream target Glyoxalase 1 (Glo1), a pivotal stress responsive defense enzyme involved in cellular protection against glycative and oxidative stress through the metabolism of methylglyoxal (MG). This is a potent post-translational protein modifier that may either contribute to increased oxidative molecular damage and cellular susceptibility to apoptosis, or enhance the activity of major apoptosis-protective proteins, including heat shock proteins (Hsps), promoting cell survival. Experimental outcomes showed that KRIT1 loss-of-function induces a redox-sensitive sustained upregulation of Nrf2 and Glo1, and a drop in intracellular levels of MG-modified Hsp70 and Hsp27 proteins, leading to a chronic adaptive redox homeostasis that counteracts intrinsic oxidative stress but increases susceptibility to oxidative DNA damage and apoptosis, sensitizing cells to further oxidative challenges. While supporting and extending the pleiotropic functions of KRIT1, these findings shed new light on the mechanistic relationship between KRIT1 loss-of-function and enhanced cell predisposition to oxidative damage, thus providing valuable new insights into CCM pathogenesis and novel options for the development of preventive and therapeutic strategies. PMID- 29170095 TI - Assessing prevalence of and barriers to medication adherence in patients with uncontrolled diabetes attending primary healthcare clinics in Qatar. AB - BACKGROUND: Studies conducted in Qatar have reported a high prevalence of diabetic nephropathy, retinopathy, and neuropathy. These complications are often associated with poor medication adherence and uncontrolled diabetes. The objectives of this study were to determine the rate of medication adherence among patients with uncontrolled diabetes, and to compare the characteristics and identified barriers between patients with good and those with poor medication adherence. METHOD: A cross-sectional quantitative study was conducted among patients living in Qatar with uncontrolled diabetes attending primary healthcare clinics from October 2016 to January 2017. An interviewer-administered questionnaire comprising three sections was utilized in the study: patients' characteristics, Adherence to Refill and Medications Scale in Diabetes (ARMS-D), and barriers to medication adherence. ARMS-D is a validated tool that is used to identify adherence level among patients with diabetes. Descriptive and inferential statistics including regression analysis were used for data analysis. RESULTS: A total of 260 patients were included in the analysis. Overall, 73% (n=191) were nonadherent to their diabetes medications (ARMS-D score above 11). Nonadherent patients reported the majority of the pre-determined barriers to medication adherence with forgetfulness being the most commonly reported barrier. Multivariate linear regression analysis found age, ethnicity, education level, income level and HbA1c to be independent predictors of adherence. CONCLUSION: The findings of this study reaffirm the notion that non-adherence to medications among patients with uncontrolled diabetes within primary care setting is higher than the general diabetes population. This high prevalence is concerning and necessitates urgent interventions. Nonetheless, an in-depth understanding of barriers to medication adherence often requires qualitative research approach as these barriers are very complex and multifactorial in nature. PMID- 29170096 TI - Pb2+ modulates ryanodine receptors from the endoplasmic reticulum in rat brain. AB - Although the neurotoxic mechanism of lead (Pb2+) has been extensively studied, it is not well understood. The effects of Pb2+ on free cytosolic calcium (Ca2+) concentration and calcium-regulated events have been suggested to be major mechanisms in Pb2+ toxicity. Based on our previous findings that Pb2+ changes calcium release through ryanodine receptors (RyRs), the modulation of endoplasmic reticulum (ER) vesicular RyRs by Pb2+ was investigated further in the present study. The results of [3H]ryanodine binding assays showed that in the presence of a free Ca2+ concentration ([Ca2+]f) of 100MUM, Pb2+ modulated the equilibrium of [3H]ryanodine binding to brain RyRs, with a U-type dose-response curve, where minimal binding was observed at a free Pb2+ concentration ([Pb2+]f) of 0.39MUM. This modulation was also observed over a time course. Scatchard analysis indicated that both an increase in Kd and a possible decrease in Bmax were responsible for the decrease in binding induced by low [Pb2+]f. Moreover, the effects of Pb2+ on the function of ER RyRs in neurons might also be controlled by other RyR modulators. Whole-cell patch-clamp experiments revealed that dynamic calcium oscillations evoked by specific RyR agonists were depressed rapidly and reversibly by exposure to 10MUM Pb2+. Our study indicates that RyRs are molecular targets of Pb2+, and this interaction disturbs Ca2+ signals and leads to neurotoxicity. PMID- 29170097 TI - Mild cognitive impairment due to Alzheimer disease: Contemporary approaches to diagnostics and pharmacological intervention. AB - Alzheimer disease (AD) and related forms of dementia are among the main medical and social problems in the economically developed countries. It is connected with significant increase in human life span in these regions and with the absence of efficient medicines for treatment and prevention of such diseases. Lack of positive results in the developing of novel drugs for AD treatment stimulates special attention on problem of early diagnosis and drug discovery for pharmacotherapy on the very early stages of dementia, in particular, on mild cognitive impairments (MCI) due to AD. Here we review the state of art in the field of MCI diagnostics and analyze the data on the pharmacological agents developed for MCI treatment, which currently are in preclinical and clinical trials. The conclusion was made that only the agents that act on the very early pathogenetic stages of the disease, when the damage of cholinergic neurons is not observed, can be efficient for pharmacotherapeutic intervention of MCI. Therefore, the focused search and design of "disease-modifying" medicines should be accepted as the most (and may be the only) efficient strategy for treatment and prevention of MCI.

AB - To explore the genetic divergence and phylogeny of Chinese indigenous sheep breeds, in the current study, we analyzed the polymorphisms of 5 structural loci in ten sheep populations, including Sishui Fur, Sunite, Wurank, Bayinbuluke, Altay, Small-Tailed Han, Wadi, Tan, Tong and Hu sheep. The data were then compared with those from an additional 13 Asian and 4 European sheep populations acquired by the same experimental method. Based on the genetic distance and the results of a cluster analysis, we constructed the phylogenetic relationship of 27 populations. The results showed that the sheep populations in this study could be classified into four genetic groups: "Mongolian", "Tibetan", "South-Southeast Asian" and "European" sheep groups. All 10 Chinese sheep breeds belonged to the "Mongolian sheep" lineage; however, Finnish Landrace sheep and Yunnan sheep could not be classified into any of the four groups. These results could provide a good reference for the protection and utilization of primary breed resources in China and phylogenic research on Asian sheep populations. PMID- 29170101 TI - A new approach of digital PCR system for non-invasive prenatal screening of trisomy 21. AB - BACKGROUND: Non-invasive prenatal screening (NIPS) of trisomy 21 (T21) using digital PCR (dPCR) with several advantages will be very effective. Here, we developed a dPCR system for T21 screening which allows high sensitivity and real time diagnosis and thus overcome sequence based analysis. METHODS: Cut-off value was established using DNA extracted from all 157 T21 negative samples including 47 pregnant woman samples and 3 T21 positive pregnant woman samples extracted from 4 different sample types. To increase the portion of the cell-free fetal DNA (cffDNA) in maternal cell-free DNA (cfDNA), a size selection method was devised. We evaluated the clinical reliability of NIPS using dPCR through analysis of 877 pregnant woman samples. RESULTS: We could demonstrate the possibility of NIPS using dPCR performed by applying cut-off value and size selection method. The overall accuracy was derived at 99.66% using 877 pregnant woman plasma samples. CONCLUSION: Our results showed that dPCR can meet the requirements for NIPS for T21. It is relatively inexpensive, easy to use in a screening method and compatible with ethical concerns regarding access to nucleotide sequence information. This study may be a basic data for the development of population wide screening for T21 in pregnant women. PMID- 29170102 TI - Pretreatment albumin to globulin ratio can serve as a prognostic marker in human cancers: a meta-analysis. AB - PURPOSE: Our meta-analysis aims to investigate the prognostic role of pretreatment albumin to globulin ratio (AGR) in human cancers. METHODS: Available databases were searched up to Sept 25th, 2017. Pooled hazard ratios (HRs) and risk ratio (RRs) with their corresponding 95% confidence intervals (CIs) were used to assess the prognostic impact of AGR on overall survival (OS)/disease-free survival (DFS)/progression-free survival (PFS) and 5-year mortality respectively. RESULTS: Totally, 28 studies with 15 356 cancer patients were included. Our results demonstrated that low pretreatment AGR is associated with poor OS (HR=2.08, 95%CI:1.78-2.44, univariate results; HR=1.75, 95%CI:1.56-1.97, multivariate results), poor DFS (HR=1.96, 95%CI:1.48-2.59, univariate results; HR=1.64, 95%CI:1.26-2.14, multivariate results) and poor PFS (HR=1.89, 95%CI:1.61 2.22, univariate results; HR=1.66, 95%CI:1.32-2.0, multivariate results). Meanwhile, low pretreatment AGR is also associated with increased 5-year mortality (RR=2.12, 95%CI:1.48-3.03). Moreover, this significant correlation was not altered by stratified analysis according to publication times, sample sizes, patient origins, AGR cutoff values, cancer systems, treatment methods or HR sources. CONCLUSION: Low pretreatment AGR is associated with poor prognosis in human cancers, and AGR should be used as a prognostic marker during cancer therapy. PMID- 29170103 TI - Gamma-glutamyl transpeptidase-to-platelet ratio predicts the prognosis in HBV associated acute-on-chronic liver failure. AB - BACKGROUND: The gamma-glutamyl transpeptidase-to-platelet ratio (GPR) is a new noninvasive marker for assessing liver fibrosis. We aimed to evaluate the performance of GPR for prediction of 90-day mortality in patients with acute-on chronic liver failure (ACLF). METHODS: A total of 355 patients with HBV associated ACLF were enrolled from two clinical centers and divided into training group (n=210) and validation group (n=145). Potential risk factors for 90-day mortality were analyzed. RESULTS: Age, MELD score and GPR were independent risk factors associated with ACLF prognosis. A new scoring system (MELD-GPR) was developed. MELD-GPR=9.211-0.029*age-0.290*MELD-0.460*GPR. For ACLF patients with liver cirrhosis, the area under the receiver operating characteristic curve (AUROC) of MELD-GPR was 0.788, which was significantly higher than that of MELD and MELD-Na (0.706 and 0.666, respectively). Patients were stratified into three groups according to MELD-GPR scores (high risk: <-0.19, intermediate risk: -0.19 0.95, and low risk: >0.95), and the high-risk group (MELD-GPR<-0.19) had a poor prognosis (P<0.01). For ACLF patients without liver cirrhosis, MELD-GPR<0.95 predicted a poor prognosis. CONCLUSIONS: Incorporating GPR into MELD may provide more accurate survival prediction in patients with HBV-ACLF. PMID- 29170104 TI - Unraveling unusual X-chromosome patterns during fragile-X syndrome genetic testing. AB - BACKGROUND: Fragile X syndrome (FXS) is the most common form of inherited intellectual disability (ID). Together with fragile X-associated tremor and ataxia (FXTAS) and fragile X-associated premature ovarian failure (POF)/primary ovarian insufficiency (POI), FXS depends on dysfunctional expression of the FMR1 gene on Xq27.3. In most cases, FXS is caused by a >200 CGG repeats in FMR1 5' untranslated region (UTR) and by promoter hypermethylation that results in gene silencing. Males and females with unmethylated premutated alleles (repeats between 55 and 200) are at risk for FXTAS and POF/POI. METHODS: FXS molecular testing relied on PCR and methylation-specific Southern blot analysis of the FMR1 5'UTR. Atypical Southern blot patterns were studied by X-chromosome microsatellite analysis, copy number dosage at DMD locus, amelogenin gender marker analysis and array-comparative genomic hybridization (array-CGH). RESULTS: Six men affected by ID and three women affected by ID and POF/POI underwent FXS molecular testing. They had normal FMR1 CGG repeats, but atypical X chromosome patterns. Further investigations revealed that the six males had Klinefelter syndrome (XXY), one female was a Turner mosaic (X0/XX) and two women had novel rearrangements involving X chromosome. CONCLUSIONS: Diagnostic investigation of atypical patterns at FMR1 locus can address patients and/or their relatives to further verify the condition by performing karyotyping and/or array-CGH.

PMID- 29170106 TI - One-year in vitro stability of cardiac troponins and galectin-3 in different sample types. AB - BACKGROUND: We assessed the long-term in vitro stability of cardiac troponins and galectin-3 under different storage conditions. METHODS: We used high-sensitivity cardiac troponin I (hs-cTnI) and galectin-3 assays from Abbott and a high sensitivity cardiac troponin T (hs-cTnT) assay from Roche. The analyte concentrations of 30 patients were measured in heparin-treated plasma, EDTA treated plasma and serum samples after the following storage conditions: 1) samples used immediately after blood collection for baseline measurements; 2) samples stored for 0.5year at -80 degrees C after one freeze-thaw cycle; 3) samples stored for 1.0year at -80 degrees C after two freeze-thaw cycles; and 4) samples stored for 1.0year at -80 degrees C after one freeze-thaw cycle. According to the concept of acceptable change limits (ACL) the analytes were considered stable as long as the median concentration at a particular time point was >80%. RESULTS: Baseline hs-cTnI, hs-cTnT and galectin-3 concentrations ranged from 2.3 to 5436ng/L, from 5.3 to 850ng/L, and from 8.3 to 79.3ng/mL, respectively. After applying the default criterion for analyte stability, the three analytes were stable for at least 1.0year even after two freeze-thaw cycles for each sample type. We observed the following variation in analyte concentrations after storage relative to the baseline values: the interquartile range (IQR) of cardiac troponin results extended from approx. 80 to 115%, and the IQR of galectin-3 results extended from approx. 90 to 110%. CONCLUSION: hs-cTnI, hs-cTnT and galectin-3 were stable under the reported storage conditions irrespective of the sample type used. However, we observed a considerable variation in analyte concentrations after sample storage, which might affect the diagnostic/prognostic value of these analytes in individual patients using frozen blood samples. PMID- 29170107 TI - Analytical and clinical comparison of two fully automated immunoassay systems for the detection of autoantibodies to extractable nuclear antigens. AB - BACKGROUND: Detection of antinuclear antibodies (ANA) by indirect immunofluorescence assay (IIFA) is increasingly substituted by fully automated solid phase immunoassays. This study evaluated the performance of an automated chemiluminescence immunoassay (CIA) and fluorescence enzyme immunoassay (FEIA) and compared their performance to that of IIFA. METHODS: The study included an unselected prospective study population suspected of systemic autoimmune rheumatic disease. ANA were measured by IIFA, while in parallel sera were tested by CIA QUANTA Flash CTD Screen Plus on the BIO-FLASH(r) and FEIA EliA CTD Screen on the Phadia(r) 250 system. As validation, retrospective cohorts of patients with ANA-associated rheumatic disease (AARD) and healthy controls were tested. RESULTS: Prospectively, sensitivity of IIFA, CIA and FEIA was 90%, 99% and 92%, respectively. Specificity was 76%, 76% and 84%, respectively. Total percent agreements between the three methods were 75.2% (IIFA vs. CIA), 79.2% (IIFA vs. FEIA) and 85.4% (FEIA vs. CIA). The AUC values were 0.95 for CIA and 0.93 for FEIA and did not significantly differ. Retrospectively in individual AARD cohorts, similar results were obtained comparing both CTD screens. CONCLUSIONS: Both FEIA and CIA CTD screen significantly outperformed IIFA, with a higher specificity for FEIA and higher sensitivity for CIA. Based on ROC analysis, major contributor to the difference between the two solid phase immunoassays was the cut-off. PMID- 29170108 TI - A mathematical multiscale model of bone remodeling, accounting for pore space specific mechanosensation. AB - While bone tissue is a hierarchically organized material, mathematical formulations of bone remodeling are often defined on the level of a millimeter sized representative volume element (RVE), "smeared" over all types of bone microstructures seen at lower observation scales. Thus, there is no explicit consideration of the fact that the biological cells and biochemical factors driving bone remodeling are actually located in differently sized pore spaces: active osteoblasts and osteoclasts can be found in the vascular pores, whereas the lacunar pores host osteocytes - bone cells originating from former osteoblasts which were then "buried" in newly deposited extracellular bone matrix. We here propose a mathematical description which considers size and shape of the pore spaces where the biological and biochemical events take place. In particular, a previously published systems biology formulation, accounting for biochemical regulatory mechanisms such as the rank-rankl-opg pathway, is cast into a multiscale framework coupled to a poromicromechanical model. The latter gives access to the vascular and lacunar pore pressures arising from macroscopic loading. Extensive experimental data on the biological consequences of this loading strongly suggest that the aforementioned pore pressures, together with the loading frequency, are essential drivers of bone remodeling. The novel approach presented here allows for satisfactory simulation of the evolution of bone tissue under various loading conditions, and for different species; including scenarios such as mechanical dis- and overuse of murine and human bone, or in osteocyte-free bone.

AB - BACKGROUND: Fibrodysplasia ossificans progressiva (FOP), is caused by mutations in the type I BMP receptor ACVR1 that lead to increased activation of the BMP pSmad1/5/8 signaling pathway. Recent findings suggest that Activin A (Act A) promiscuously stimulates the bone morphogenetic protein (BMP) signaling pathway in vitro and mediates heterotopic ossification (HO) in mouse models of FOP, but primary data from FOP patient cells are lacking. OBJECTIVE: To examine BMP pSmad1/5/8 pathway signaling and chondro-osseous differentiation in response to endogenous and exogenous Act A in primary connective tissue progenitor cells [CTPCs; also known as stem cells from human exfoliated deciduous teeth (SHED) cells] from patients with FOP. These cells express the common FOP mutation, ACVR1 (R206H). RESULTS: We found that Act A amplifies dysregulated BMP pathway signaling in human FOP primary CTPCs cells through the Smad1/5/8 pathway and induces chondro-osseous differentiation. Amplification of BMP-pSmad1/5/8 signaling was inhibited by Follistatin and by a neutralizing antibody to Activin A. The increased basal pSmad1/5/8 activity, as well as the hypoxia-induced stimulation of FOP CTPCs cells, were BMP4 and Act A independent. Importantly, either BMP4 or Act A stimulated pSmad1/5/8 pathway signaling but BMP4 signaling was not dependent on Activin A and vice versa. Circulating plasma levels of Act A or BMP4 are similar in controls compared to FOP patients, and suggest the potential for an autocrine or paracrine route for pathological signaling. CONCLUSIONS: The mutated FOP receptor [ACVR1 (R206H)] is hypersensitive to BMP4 and uniquely sensitive (compared to the wild type receptor) to Act A. Both canonical and non-canonical ligands have a synergistic effect on BMP-pSmad1/5/8 signaling in FOP CTPCs and may cooperate to alter the threshold for HO in FOP. Our findings in primary human FOP CTPCs have important implications for the design of clinical trials to inhibit dysregulated BMP pathway signaling in humans who have FOP. PMID- 29170110 TI - Association of anti-HER2 antibody with graphene oxide for curative treatment of osteosarcoma. AB - The finding of HER2 overexpression in osteosarcoma (OS) makes HER2 a potential therapeutic target. However, studies indicate OS cells are nonresponsive to anti HER2 antibody trastuzumab (TRA) therapy. We established stable, non-covalent association of TRA with nanomaterial graphene oxide (GO) to generated multivalent TRA/GO complexes that demonstrated markedly enhanced HER2-binding activity and capacity to rapidly kill OS cells. TRA/GO simultaneously induced oxidative stress and HER2 signaling in the target cells, leading to rapid depletion of the cellular inhibitors of apoptosis protein (cIAP) and caspase-8, formation of RIP1/RIPK3/MLKL necroptosome and necroptosis of the OS cells. Intravenous administration of TRA/GO eradicated established xenograft the OS in immunodeficient mice, resulting in indefinite survival of the animals, whereas TRA in its original form failed to do so. No appreciable side effects were observed with TRA/GO therapy. The results demonstrate a novel, nontoxic, curative therapy for a HER2pos cancer in a preclinical animal model. PMID- 29170111 TI - TAT-modified self-assembled cationic peptide nanoparticles as an efficient antibacterial agent. AB - The increasing emergence of drug resistant pathogenic bacteria poses a great challenge to clinical therapy and a threat to public health. Cationic peptides have received great attention for their unique antibacterial mechanism and ability to combat drug-resistant bacteria. In this study, we designed a TAT modified cationic peptide PA-28 which self-assembled into nanoparticles of about 150 nm. These nanoparticles showed strong antimicrobial activities against both gram-positive and gram-negative bacteria, including drug-resistant bacteria. They were more potent than the unassembled counterpart peptide nonalysine (K9). Their antibacterial mechanism of directly destructing bacterial wall/membrane reduces the possibility of developing bacterial resistance. In vivo anti-infective experiments showed that these nanoparticles were able to penetrate the blood brain barrier to inhibit bacterial growth in infected brains of rats. In addition, these nanoparticles induced low hemolysis below the minimum inhibitory concentration. Therefore, the peptide designed in this study is a promising and efficient antibacterial agent against bacterial infections. PMID- 29170112 TI - Nanocellulose reinforced gellan-gum hydrogels as potential biological substitutes for annulus fibrosus tissue regeneration. AB - Intervertebral disc (IVD) degeneration is associated with both structural damage and aging related degeneration. Annulus fibrosus (AF) defects such as annular tears, herniation and discectomy require novel tissue engineering strategies to functionally repair AF tissue. An ideal construct will repair the AF by providing physical and biological support, facilitating regeneration. The presented strategy herein proposes a gellan gum-based construct reinforced with cellulose nanocrystals (nCell) as a biological self-gelling AF substitute. Nanocomposite hydrogels were fabricated and characterized with respect to hydrogel swelling capacity, degradation rate in vitro and mechanical properties. Rheological evaluation on the nanocomposites demonstrated the GGMA reinforcement with nCell promoted matrix entanglement with higher scaffold stiffness observed upon ionic crosslinking. Compressive mechanical tests demonstrated compressive modulus values close to those of the human AF tissue. Furthermore, cell culture studies with encapsulated bovine AF cells indicated that nanocomposite constructs promoted cell viability and a physiologically relevant cell morphology for up to fourteen days in vitro. PMID- 29170113 TI - Anti-Adherent Biomaterials for Prevention of Catheter Biofouling. AB - Medical device-associated infections present a leading global healthcare challenge, and effective strategies to prevent infections are urgently required. Herein, we present an innovative anti-adherent hydrogel copolymer as a candidate catheter coating with complementary hydrophobic drug-carrying and eluting capacities. The amphiphilic block copolymer, Poloxamer 188, was chemically derivatized with methacryloyl moieties and copolymerized with the hydrogel monomer, 2-hydroxyethyl methacrylate. Performance of the synthesized copolymers was evaluated in terms of equilibrium swelling, surface water wettability, mechanical integrity, resistance to encrustation and bacterial adherence, and ability to control release of the loaded fluoroquinolone antibiotic, ofloxacin. The developed matrices were able to provide significant protection from fouling, with observed reductions of over 90% in both adherence of the common urinary pathogen Escherichia coli and encrusting crystalline deposits of calcium and magnesium salts relative to the commonly employed hydrogel, poly (hydroxyethyl methacrylate). Additionally, the release kinetics of a loaded hydrophobic drug could be readily tuned through facile manipulation of polymer composition. This combinatorial approach shows significant promise in the development of suitable systems for prevention of catheter-associated infections. PMID- 29170114 TI - Protein-alginate complexes as pH-/ion-sensitive carriers of proteins. AB - Protein-alginate complexes were prepared with the objective of quantifying the influence of the parameters such as protein characteristics on the final complex properties and their dissociation rates. Cytochrome C, lysozyme, myoglobin, chymotrypsin, and bovine serum albumin were used as model proteins for preparing the complexes and physical properties such as composition, average diameter, and zeta potential of the complexes formed were measured. In addition, protein release kinetics from the complexes in response to changes in pH and ionic strength were investigated. The results clearly demonstrated that, even in the absence of a cation, proteins could be complexed with alginate and showed a decreased release rate under the appropriate conditions. Projection to Latent Structures was applied as a multivariate statistical analysis method to mathematically describe the final properties and the protein release kinetics as a function of the influencing variables. It was found that the physical characteristics of the complexes could be accurately modelled with low error thresholds indicative of good fit and prediction capabilities of the model. The statistical model indicated that the release kinetics parameters were highly dependent on the ionic strength and the protein net charge as a function of pH, demonstrating the potential use of these complexes in ion-/pH-sensitive delivery systems. PMID- 29170115 TI - Incorporation of surface-modified dry micronized poorly water-soluble drug powders into polymer strip films. AB - Recent work has established polymer strip films as a robust platform for delivery of poorly water-soluble drugs via slurry casting, in particular using stable drug nanosuspensions. Here, a simpler, robust method to directly incorporate dry micronized poorly water-soluble drug, fenofibrate (FNB), is introduced. As a major novelty, simultaneous surface modification using hydrophilic silica along with micronization was done using fluid energy mill (FEM) in order to reduce FNB hydrophobicity and powder agglomeration. It is hypothesized that silica coating promotes easy, uniform dispersion of micronized and coated FNB (MC-FNB) during direct mixing with aqueous hydroxypropyl methylcellulose (HPMC-E15LV) and glycerin solutions. Uniform dispersion leads to improved film critical quality attributes (CQAs) such as appearance, drug content uniformity and drug dissolution. The impact of polymer solution viscosity (low and high), mixer type (low versus high shear), and FNB surface modification on film CQAs were also assessed. Films with as-received FNB (AR-FNB) and micronized uncoated FNB (MU FNB) were prepared as control. When MC-FNB powders were used, films exhibited improved appearance (thickness uniformity, visible lumps/agglomerates), better drug content uniformity (expressed as relative standard deviation), fast and immediate drug release, and enhanced mechanical properties (tensile strength, elongation percentage), regardless of the polymer solution viscosity or mixer type. These results compare favorably with those reported using nanosuspensions of FNB, establishing the feasibility of directly incorporating surface modified micronized poorly water-soluble drug powders in film manufacturing. PMID- 29170116 TI - In vivo controlled release of fenretinide from long-acting release depots for chemoprevention of oral squamous cell carcinoma recurrence. AB - Local, long-acting release fenretinide (4HPR) millicylindrical implants were prepared and evaluated for their release kinetics in vivo and their ability to suppress oral cancer tumor explant growth. Poly(lactic-co-glycolic acid)(PLGA) implants were prepared as a function of drug loading and the presence of various excipients (pore-formers, solubilizers, crystallization inhibitors) to enhance release of the insoluble 4HPR. Release kinetics and bioerosion of PLGA were monitored both in vitro in a PBS/Tween 80 buffer and in vivo by recovery of the drug remaining at the injection site. 4HPR was released from PLGA implants much slower in vivo than in the drug solubilizing media in vitro, with a 3-week lag phase and continuous release of >2 months, but showed some release enhancement by addition of solubilizers. Water-soluble PVA/sucrose implants for release of 4HPR served to determine if drug dissolution provided suitable controlled release without the PLGA, and this formulation showed continuous drug release over 6 weeks in vivo. Placement of PLGA-4HPR implants adjacent to oral cancer tumor murine xenografts showed inhibition of tumor growth relative to sham implants, indicating the potential for the local 4HPR delivery approach to be useful for oral cancer chemoprevention. PMID- 29170117 TI - Investigation of microemulsion and microemulsion gel formulations for dermal delivery of clotrimazole. AB - Dermal delivery of hydrophobic drugs by microemulsion (ME) formulations and effect from ME microstructures were studied. Anti-fungal drug, clotrimazole (CLOT), was used as the model compound. ME formulations possessing different microstructures were prepared using a ME system that contains isopropyl myristate as oil, Labrasol and Cremophor EL as surfactant and co-surfactant, and water. Permeation experiments on human cadaver skin were conducted for ME and the control formulations of different CLOT concentrations. Dermal delivery of CLOT assessed by the dermal tissue drug concentration was found to be significantly higher for MEs when compared with the control formulation, evidenced by dermal retention Enhancement Ratio (ERD) of 5.1, 2.8, and 3.0 for tested O/W, bi continuous, and W/O MEs, respectively. The highest concentration was observed with O/W ME, suggesting the ME microstructure is an important formulation variable for enhancing dermal delivery efficiency. ME gel formulations prepared by incorporating 1.0%(w/w) of Carbopol980 showed comparable dermal CLOT concentration to MEs, but up to 2.4 fold higher than the commercial CLOT cream product, Lotrimin(r). Furthermore, Fluorescein Isothiocynate (FITC), used as a model compound for highly hydrophobic drugs, was also studied for dermal delivery by MEs, and results show consistent ME microstructure effect, suggested by significantly higher FITC concentrations in all skin layers, SC, viable epidermis, and dermis, from O/W ME over bi-continuous and W/O MEs. PMID- 29170118 TI - Generic drug device combination products: Regulatory and scientific considerations. AB - Complex regulatory and scientific considerations exist for drug-device combination products submitted under an Abbreviated New Drug Application. The Agency has published several guidances to aid industry in the development of a generic drug-device combination product: providing recommendations on the types of studies necessary to establish bioequivalence, providing considerations on product quality and performance for certain types of device constituents, and most recently, providing tools to assess the proposed user interface when compared to the user interface of the Reference Listed Drug. In addition, the Office of Generic Drugs1 has established a regulatory science research program intended to support projects that examine scientific questions relating to the development of generic combination products and their associated regulatory review. Several research examples are described within this article, which demonstrate how equivalence can be evaluated when the function of the device could potentially impact drug delivery. Moreover, this article provides an overview of regulatory recommendations and ongoing scientific research efforts to further develop guidances and ultimately improve public access to generic combination products. PMID- 29170119 TI - Adult Patients with Pneumococcal Meningitis at a Neurosurgical Neurologic Center: Different Predisposing Conditions? AB - BACKGROUND: In previous studies of pneumococcal meningitis in adults within general hospitals or national cohorts, the most common predisposing conditions were otitis media, sinusitis, pneumonia, immunosuppression, alcoholism, and diabetes. The epidemiology of pneumococcal meningitis is changing because of the use of vaccines in childhood, and antibiotic resistance has increased. METHODS: We retrospectively reviewed the cases of patients with diagnoses of pneumococcal meningitis proved by an inflammatory cerebrospinal fluid (CSF) with a positive culture, treated during a period of 14 years at an adult neurosurgical neurologic referral center. Our aim was to define their clinical course, predisposing conditions, antimicrobial susceptibilities, and outcome. RESULTS: We reviewed the cases of 30 patients, 17 men and 13 women, with a mean age of 36.7 years. Fourteen patients (46.6%) had previous neurosurgery, 12 patients (40%) had CSF fistula, 8 had remote head trauma, and 8 also presented recurrent meningitis. Resistance to ceftriaxone or vancomycin was less than 5%, and penicillin resistance was 53%. Eight patients (26.7%) had died. An increased risk of death was associated with coma at admission, septic shock, upper gastrointestinal bleeding, mechanical ventilation, thrombocytopenia, and a low CSF opening pressure. CONCLUSIONS: We conclude that patients with pneumococcal meningitis treated at neurosurgical neurologic centers have different predisposing conditions with severe disease and high mortality, thus prompting us to recommend aggressive pneumococcal vaccination in patients with CSF leaks and severe head trauma. Prospective studies to identify which neurosurgical patients may benefit in the long term from a pneumococcal vaccine are urgently needed. PMID- 29170120 TI - Peripheral Blood Biomarkers Associated with Clinical Outcome in Non-Small Cell Lung Cancer Patients Treated with Nivolumab. AB - OBJECTIVE: The aim of this study was to identify baseline peripheral blood biomarkers associated with clinical outcome in patients with NSCLC treated with nivolumab. METHODS: Univariable and multivariable analyses were performed retrospectively for 134 patients with advanced or recurrent NSCLC treated with nivolumab to evaluate the relationship between survival and peripheral blood parameters measured before treatment initiation, including absolute neutrophil count (ANC), absolute lymphocyte count (ALC), absolute monocyte count, and absolute eosinophil count (AEC), as well as serum C-reactive protein and lactate dehydrogenase levels. Progression-free survival, overall survival, and response rate were determined. RESULTS: Among the variables selected by univariable analysis, a low ANC, high ALC, and high AEC were significantly and independently associated with both better progression-free survival (p = 0.001, p = 0.04, and p = 0.02, respectively) and better overall survival (p = 0.03, p = 0.03, and p = 0.003, respectively) in multivariable analysis. Categorization of patients according to the number of favorable factors revealed that those with only one factor had a significantly worse outcome than those with two or three factors. A similar trend was apparent for patients with a programmed death 1 ligand tumor proportion score less than 50%, whereas all patients with a score of 50% or higher had at least two favorable factors. CONCLUSIONS: A baseline signature of a low ANC, high ALC, and high AEC was associated with a better outcome of nivolumab treatment, with the number of favorable factors identifying subgroups of patients differing in survival and response rate. PMID- 29170121 TI - Personal relative deprivation increases self-selected portion sizes and food intake. AB - Cues and experiences of the deprivation of financial/material resources have been associated with increased caloric intake and risk for overweight/obesity. Given that social comparisons may serve as a powerful reference for the adequacy of one's standing and resources, the present research tested whether subjective feelings of personal relative deprivation (PRD) or "losing out" to others stimulates calorie selection and intake. Study 1 demonstrated that self-reported chronic experiences of PRD positively predicted calories selected for a portion and consumed during an ad-libitum meal. Study 2 revealed that experimentally induced PRD resulted in an increase in the amount of calories selected on a portion selection task and a stronger desire to consume the foods. Consequently, these findings demonstrate that chronic and acute subjective deprivation of non food resources may contribute to socioeconomic gradients in obesity, and that perceived social inequality may have inherently obesogenic properties that promote excess calorie intake. PMID- 29170122 TI - Kudinoside-D, a triterpenoid saponin derived from Ilex kudingcha suppresses adipogenesis through modulation of the AMPK pathway in 3T3-L1 adipocytes. AB - The leaves of Ilex Kudingcha, locally named "Kudingcha" in China, has been traditionally applied for treating obesity. Studies have demonstrated that the ethanol extract of Ilex kudingcha have anti-adipogenic effects. However, the constituent which was responsible for its anti-obesity and its underlying molecular mechanism has not yet been elucidated. This research explored the anti obesity effect of kudinoside-D which was a main natural component of triterpenoid saponin from the ethanol extract of Ilex kudingcha, on lipid accumulation and the potential mechanism of action of adipogenesis in 3T3-L1 adipocytes. The adipocytes were treated with various concentrations of kudinoside D (0 to 40MUM) during differentiation. The image-based Oil Red O staining analyses revealed that KD-D, dose dependently reduced cytoplasmic lipid droplet in 3T3-L1 adipocytes with the IC50 is 59.49MUM. Meanwhile, major adipogenic transcription factor peroxisome proliferator-activated receptor gamma (PPARgamma), CCAAT/enhancer binding protein-alpha (C/EBPalpha) and sterol regulatory element-binding protein 1c (SREBP-1c) were significantly repressed as well as their target genes. The phosphorylation of AMP-activated protein kinase (AMPK) and its downstream target phosphorylated-acetyl CoA carboxylase (ACC) expression were also increased. In addition, the inhibitory effects of KD-D on the expressions of PPARgamma and C/EBPalpha were weakened when cells were cotreated with AMPK inhibitor Compound C. These results indicated KD-D exerts anti-adipogenic effects through modulation of adipogenic transcription factors via AMPK signaling pathway. And the current findings demonstrated that KD-D was a potential therapeutic candidate for alleviating obesity and hyperlipidemia.

AB - Seven new glucosyloxybenzyl 2R-benzylmalate derivatives, arundinosides A-G (1-7) were isolated from the aerial parts of the bamboo orchid Arundina graminifolia. This is the first occurrence of this class of compounds in the genus Arundina. Their planar structures and absolute configuration were determined by extensive NMR spectroscopic data as well as chemical conversion. Their neuroprotective properties were also evaluated on their potential ability to reduce the beta amyloid damage on PC12 cell model. PMID- 29170124 TI - Long non-coding RNA LUCAT1 modulates methotrexate resistance in osteosarcoma via miR-200c/ABCB1 axis. AB - Long non-coding RNAs (lncRNAs) have been verified to participate in the tumorigenesis of multiple cancers. Nevertheless, the deepgoing role molecular mechanisms of lncRNAs on osteosarcoma chemoresistance remain unclear. In present study, we investigate the function of lncRNA LUCAT1 on osteosarcoma methotrexate (MTX) resistant phenotype and discover the potential regulatory mechanism. Results showed that LUCAT1 was up-regulated in MTX-resistant cells (MG63/MTX, HOS/MTX) compared to that in parental cells. LncRNA LUCAT1 and ABCB1 protein expression levels were both up-regulated when induced by different concentration of methotrexate. In vitro and vivo, LUCAT1 knockdown decreased the expression levels drug resistance related genes (MDR1, MRP5, LRP1), proliferation, invasion and tumor growth of osteosarcoma cells. Bioinformatics tools and luciferase assay reveled that miR-200c both targeted the 3'-UTR of LUCAT1 and ABCB1 mRNA, suggesting the modulation of LUCAT1 on ABCB1 through sponging miR-200c. Rescue experiments confirmed the combined role of LUCAT1, miR-200c and ABCB1 on osteosarcoma proliferation, invasion and methotrexate resistance. Overall, results indicate the vital role of LUCAT1 in the methotrexate resistance regulation through miR-200c/ABCB1 pathway, providing a novel insight and treatment strategy for osteosarcoma drug resistance. PMID- 29170125 TI - S-layer glycoprotein from Lactobacillus kefiri CIDCA 8348 enhances macrophages response to LPS in a Ca+2-dependent manner. AB - The S-layer is a (glyco)-proteinaceous envelope constituted by self-assembled subunits that form a two-dimensional lattice covering the surface of different species of Bacteria and Archaea. It could be considered as one of the most abundant biopolymers in our planet. Because of their unique self-assembly features, exhibiting repetitive identical physicochemical properties down to the subnanometer scale, as well as their involvement in specific interactions with host cells, the S-layer proteins (SLPs) show a high potential application in different areas of biotechnology, including the development of antigen carriers or new adjuvants. The presence of a glycosylated SLP on potentially probiotic Lactobacillus kefiri strains was previously described by our research group. In this study, we aim to investigate the role of carbohydrates present in the SLP from L. kefiri CIDCA 8348 (SLP-8348) in their internalization by murine macrophages, as well as to analyze their immunomodulatory capacity and their effect on LPS-stimulated macrophages. RAW 264.7 cells internalized the SLP-8348 in a process that was mediated by carbohydrate-receptor interactions since it was inhibited by glucose, mannose or EGTA, a Ca+2 chelating agent. These results correlated with the recognition of SLP-8348 by ConA lectin. We further show that while SLP-8348 was not able to induce the activation of macrophages by itself, it favored the LPS-induced response, since there was a significant increase in the expression of surface cell markers MHC-II, CD86 and CD40, as well as in IL-6 and IL-10 expression at both transcript and protein levels, in comparison with LPS stimulated cells. The presence of EGTA completely abrogated this synergistic effect. Taken together, these results strongly suggest the involvement of both glycosidic residues and Ca+2 ions in the recognition of SLP-8348 by cellular receptors on murine macrophages. Moreover, these results suggest the potentiality of the SLP-8348 for the development of new adjuvants capable of stimulating antigen presenting cells by interaction with glycan receptors. PMID- 29170126 TI - Role of cAMP in phenotypic changes of osteoblasts. AB - Bone remodeling is precisely controlled by bone formation and bone resorption, and osteoblasts are responsible for both processes. Osteoblasts exhibit an osteoclastogenic phenotype in response to elevated intracellular cyclic AMP [cAMP]i levels. However, the role of cAMP in osteoblasts acquiring an osteogenic phenotype is controversial. To elucidate the effect of cAMP on both phenotypes, an osteoblast-like cell line, TMS-12, was established in our laboratory and used in this study. Dibutyryl-cAMP (dBcAMP), a cAMP analogue, inhibited mineralization in TMS-12 cells and MC3T3E1 cells (an osteoblast-like cell line) but promoted osteoclast-supporting activity in TMS-12 cells. Moreover, mineralization was inhibited in glucagon receptor-transduced TMS-12 cells (TMS-12GCGR) after glucagon treatment to increase endogenous [cAMP]i levels. However, the osteoclast supporting activity of TMS-12GCGR cells was stimulated by glucagon treatment. These cAMP-induced phenotypic changes of osteoblasts were also supported by their gene expression profile. These results suggest that [cAMP]i is an important factor mediating phenotypic changes of osteoblasts. Our findings may provide valuable insights into the mechanisms that underlie bone remodeling in both, healthy and diseased states. PMID- 29170127 TI - miR-455-3p serves as prognostic factor and regulates the proliferation and migration of non-small cell lung cancer through targeting HOXB5. AB - MicroRNAs (miRs) have been reported to play significantly roles in the initiation and progression of human cancers. miR-455-3p has been recently found could function as tumor suppressor in various human cancers. However, its expression and biological role in non-small cell lung cancer (NSCLC) remains elusive. In this study, we found miR-455-3p was markedly downregulated in NSCLC tissues and cell lines. Chi-square test to analyze the correlations between miR-455-3p expression and clinicopathological features revealed that miR-455-3p expression was correlated with poorly differentiated cancer and advanced tumor stage (P < 0.05). Kaplan-Meier curve revealed that low expression of miR-455-3p was correlated with shorter 5-year survival time (P = 0.029). Univariate and multivariate analyses identified low miR-455-3p expression was an unfavorable prognostic factor for overall survival. Gain-of-function and loss-of-function studies revealed that miR-455-3p inhibits cell proliferation and migration in vitro. Computer algorithm and dual-luciferase reporter assay revealed that miR 455-3p directly targets and suppresses HOXB5 in NSCLC. Further studies demonstrated that knockdown of HOXB5 attenuated the effect of miR-455-3p downregulation on cell proliferation and migration. Taken together, our results for the first time suggested that miR-455-3p was downregulated in NSCLC and was correlated with the poor prognosis of NSCLC patients. Also, miR-455-3p functions as tumor suppressor by directly targeting HOXB5 in NSCLC progression and may be used as a potential target for NSCLC treatment. PMID- 29170128 TI - Cerebrospinal fluid CD4+ T lymphocyte-derived miRNA-let-7b can enhances the diagnostic performance of Alzheimer's disease biomarkers. AB - Alzheimer's disease is very difficult to clinically diagnose. miRNAs constitute the promising next generation of Alzheimer's disease (AD) biomarkers and have the potential to diagnose neurodegenerative diseases. In this study, 94 subjects underwent extensive dementia screening. Let-7b miRNA was found to increase in association with the progression of AD, and the increase in let-7b miRNA was mainly due to CD4+ T cells in the cerebrospinal fluid (CSF). Additionally, let-7b was positively correlated with the expression of t-Tau and p-Tau. The inclusion of let-7b in Abeta40-Abeta42 or t-tau-p-tau logistic regression and receiver operating characteristic predictive models can significantly improve the diagnostic performance. Overall, let-7b has an important association with the pathology of AD and can be used as an adjunct to improve the diagnostic performance of traditional AD biomarkers. PMID- 29170129 TI - Rbfox family proteins make the homo- and hetero-oligomeric complexes. AB - Rbfox family of proteins that consists of Rbfox1, Rbfox2, and Rbfox3 in mammals regulates alternative pre-mRNA splicing in various tissues via direct binding to their RNA binding element. Although many studies have indicated the splicing activity of each member of the Rbfox family, the interactions of Rbfox family proteins are largely unknown. Here, we have investigated interactions among Rbfox family proteins. Co-immunoprecipitation (Co-IP) and GST-pull down assays confirmed that Rbfox proteins form homo and hetero complexes. Moreover, in vivo crosslinking using disuccinimidyl suberate treatment indicated that the Rbfox proteins form a dimer which then assembles with other proteins to form a large multiprotein complex. Duolink in situ proximity ligation (PLA) assay revealed that neuron specific Rbfox3 protein interacts with other Rbfox family proteins. This study is the first to provide an evidence that Rbfox family proteins form homo- and hetero-oligomeric complexes in vivo. PMID- 29170130 TI - MicroRNA-140 suppresses osteosarcoma tumor growth by enhancing anti-tumor immune response and blocking mTOR signaling. AB - Immune checkpoint blockade is proved to be a promising therapeutic strategy against several human malignancies. MicroRNAs (miRNAs) are ~22 nucleotide RNAs that play important roles in regulating gene expression, either suppressing its translation or speeding up its degradation. In this study, we demonstrated that miR-140 acts as a critical modulator of PD-L1 and is significantly reduced in osteosarcoma (OS). MiR-140 was inversely correlated with PD-L1 and luciferase reporter assay confirmed that miR-140 can direct regulate PD-L1 expression by binding to its 3'UTR. MiR-140 failed to influence tumor growth in nude mice, whereas markedly inhibited tumor growth in the immune-competent C57BL/6J mice. Mechanistically, the tumor-suppressive role of miR-140 was associated with the increased infiltrates of cytotoxic CD8+ T cells and the decreased infiltrates of myeloid-derived suppressive cells and regulatory T cells. Moreover, miR-140 significantly inhibited mTOR signaling and combined miR-140 overexpression with pharmacological inhibition of mTOR signaling showed remarkable synergistic anti tumor effect. Collectively, our findings indicate that miR-140 exerts anti-OS efficacy by targeting immune checkpoint molecule PD-L1 and can be developed as a novel immunotherapeutic agent for the treatment of OS. PMID- 29170132 TI - High ALDH activity defines ovarian cancer stem-like cells with enhanced invasiveness and EMT progress which are responsible for tumor invasion. AB - Epithelial ovarian cancer (EOC) is highly metastatic and current therapeutics are unsatisfactory. Cancer stem/stem-like cells (CSCs/CSCLs) represent a rare population of undifferentiated oncogenic cells responsible for tumor initiation and maintenance. We identified ovarian cancer ALDHhigh (aldehyde dehydrogenase) population could perform not only strengthened CSCLs properties embodied in colony-formation, CSCs-markers expression, and tumorigenesis in vivo, but also a greater invasive capacity with advanced EMT progress and anti-apoptosis compared with ALDHlow cells. Furthermore, both the stemness and aggressive features, along with ALDHhigh percentages were in positive association with the invasiveness of cell lines for sorting, indicating the promotive role of ALDHhigh CSCLs in EOC neoplasia and metastasis, since the whole tumor was derived from the CSCLs with hyperactive self-renewal and aggression. Collectively, this study illustrates the interplay between ALDHhigh CSCLs and EOC invasion, and offers a novel application target for the EOC oncotherapy. PMID- 29170131 TI - Negative regulation of lncRNA GAS5 by miR-196a inhibits esophageal squamous cell carcinoma growth. AB - MiR-196a could play important roles in carcinogenesis by targeting many protein coding genes. However, little is known about whether miR-196a can target any long non-coding RNAs (lncRNAs). In the present study, we screen lncRNAs which are regulated by miRNA-196a in human esophageal squamous cell carcinoma (ESCC). We found that miR-196a could suppress the expression of lncRNA growth arrest specific 5(GAS5). GAS5 is frequently down-regulated in 86 paired human ESCC tissues. Importantly, there was lower GAS5 expression in the late stage of ESCC patients. The reduced expression of GAS5 in ESCC may not be related to DNA methylation but related to the high expression of miR-196a. In vitro and in vivo studies indicated that GAS5 could inhibit the growth of ESCC cells. Using Chromatin Isolation by RNA Purification-qPCR, we found that miR-196a could bind to GAS5. The Luciferase Reporter Assay indicated that miR-196a could bind to the seventh exon of GAS5. Additionally, both GAS5 and miR-196a could bind to Ago2 which is a key component of the RNA-induced silencing complex (RISC). Together, these results suggest that GAS5 functions as a tumor suppressor gene in ESCC and is regulated by miR-196a involved in RISC.

AB - The mitochondrial Bit1 protein exerts tumor-suppressive function in NSCLC through induction of anoikis and inhibition of EMT. Having this dual tumor suppressive effect, its downregulation in the established human lung adenocarcinoma A549 cell line resulted in potentiation of tumorigenicity and metastasis in vivo. However, the exact role of Bit1 in regulating malignant growth and transformation of human lung epithelial cells, which are origin of most forms of human lung cancers, has not been examined. To this end, we have downregulated the endogenous Bit1 expression in the immortalized non-tumorigenic human bronchial epithelial BEAS-2B cells. Knockdown of Bit1 enhanced the growth and anoikis insensitivity of BEAS-2B cells. In line with their acquired anoikis resistance, the Bit1 knockdown BEAS-2B cells exhibited enhanced anchorage-independent growth in vitro but failed to form tumors in vivo. The loss of Bit1-induced transformed phenotypes was in part attributable to the repression of E-cadherin expression since forced exogenous E cadherin expression attenuated the malignant phenotypes of the Bit1 knockdown cells. Importantly, we show that the loss of Bit1 expression in BEAS-2B cells resulted in increased Erk activation, which functions upstream to promote TLE1 mediated transcriptional repression of E-cadherin. These collective findings indicate that loss of Bit1 expression contributes to the acquisition of malignant phenotype of human lung epithelial cells via Erk activation-induced suppression of E-cadherin expression. PMID- 29170135 TI - Temporally coordinated spiking activity of human induced pluripotent stem cell derived neurons co-cultured with astrocytes. AB - In culture conditions, human induced-pluripotent stem cells (hiPSC)-derived neurons form synaptic connections with other cells and establish neuronal networks, which are expected to be an in vitro model system for drug discovery screening and toxicity testing. While early studies demonstrated effects of co culture of hiPSC-derived neurons with astroglial cells on survival and maturation of hiPSC-derived neurons, the population spiking patterns of such hiPSC-derived neurons have not been fully characterized. In this study, we analyzed temporal spiking patterns of hiPSC-derived neurons recorded by a multi-electrode array system. We discovered that specific sets of hiPSC-derived neurons co-cultured with astrocytes showed more frequent and highly coherent non-random synchronized spike trains and more dynamic changes in overall spike patterns over time. These temporally coordinated spiking patterns are physiological signs of organized circuits of hiPSC-derived neurons and suggest benefits of co-culture of hiPSC derived neurons with astrocytes. PMID- 29170134 TI - Synergistic chemo-photothermal therapy of tumor by hollow carbon nanospheres. AB - Combined use of different therapies is conducive to improve the effectiveness of cancer therapy. The chemo-photothermal therapy is commonly used in one nanocarrier to provide an excellent synergistic effect for cancer therapy over photothermal therapy (PTT) or chemotherapy alone. In this study, biocompatible and monodisperse hollow carbon nanospheres (HCNs) were developed as a multifunctional platform for the delivery of paclitaxel (PTX) and PTT of cancer simultaneously. The mesoporous HCNs have large pore volume and proper channels for loading and release of PTX. Upon near-infrared (NIR) laser illumination, the photothermal mediator of HCNs could effectively convert absorbed light into heat, which triggered rapid release of chemotherapeutic drug from HCNs through dissociating the interactions between PTX and HCNs by heat energy. A large number of tumor cells were significantly destroyed when hct116 cells treated with PTX@HCNs were irradiated, which was mainly attribute to the synergistic result of HCNs-mediated photothermal damage and cytotoxicity of light-triggered PTX release. PMID- 29170136 TI - Cereblon deficiency confers resistance against polymicrobial sepsis by the activation of AMP activated protein kinase and heme-oxygenase-1. AB - Cereblon (CRBN) has a pleiotropic role in important cellular processes and is a potential therapeutic target in several diseases, including mental retardation, cancer, and metabolic disorders. The role of CRBN in polymicrobial sepsis induced by cecal ligation and puncture (CLP) was investigated using CRBN-deficient (KO) mice. Survival following CLP was significantly higher in KO mice compared to wild type (WT) controls (50% vs 0% at day 6 after CLP). The improved survival of KO mice was accompanied by reduced peripheral blood bacterial load and lung injury. Serum tumor necrosis factor (TNF)-alpha and high mobility group box 1 (HMGB1) concentrations were significantly lower in KO mice than in WT mice. Peritoneal macrophages from KO mice with CLP-induced septic mouse had higher levels of activation of AMPK and heme oxygenase-1 (HO-1). Forced expression of CRBN in macrophage of KO mice suppressed activation of 5' adenosine monophosphate activated protein kinase (AMPK) and HO-1 and augmented expression of TNF-alpha and HMGB1 as inhibition of AMPK by compound C. These studies demonstrate the contribution of CRBN expression to the pathogenesis of CLP-induced sepsis and peritoneal macrophage responses and suggest a novel therapeutic modality for polymicrobial sepsis.

The characteristic fluorescence emission property of C-dots establishes their role in optical imaging. C-dots which are superior to fluorescent dyes and semiconductor quantum dots act as a safer in vivo imaging probe. Apart from their bioimaging application, other applications in biomedicine such as drug delivery, cancer therapy, and gene delivery were studied. In this review, we present multifaceted applications of C-dots along with their synthesis, surface passivation, doping, and toxicity profile. PMID- 29170140 TI - A novel controlled release formulation of the Pin1 inhibitor ATRA to improve liver cancer therapy by simultaneously blocking multiple cancer pathways. AB - Hepatocellular carcinoma (HCC) is the second leading cause of cancer deaths worldwide largely due to lack of effective targeted drugs to simultaneously block multiple cancer-driving pathways. The identification of all-trans retinoic acid (ATRA) as a potent Pin1 inhibitor provides a promising candidate for HCC targeted therapy because Pin1 is overexpressed in most HCC and activates numerous cancer driving pathways. However, the efficacy of ATRA against solid tumors is limited due to its short half-life of 45min in humans. A slow-releasing ATRA formulation inhibits solid tumors such as HCC, but can be used only in animals. Here, we developed a one-step, cost-effective route to produce a novel biocompatible, biodegradable, and non-toxic controlled release formulation of ATRA for effective HCC therapy. We used supercritical carbon dioxide process to encapsulate ATRA in largely uniform poly L-lactic acid (PLLA) microparticles, with the efficiency of 91.4% and yield of 68.3%, and ~4-fold higher Cmax and AUC over the slow-releasing ATRA formulation. ATRA-PLLA microparticles had good biocompatibility, and significantly enhanced the inhibitory potency of ATRA on HCC cell growth, improving IC50 by over 3-fold. ATRA-PLLA microparticles exerted its efficacy likely through degrading Pin1 and inhibiting multiple Pin1-regulated cancer pathways and cell cycle progression. Indeed, Pin1 knock-down abolished ATRA inhibitory effects on HCC cells and ATRA-PLLA did not inhibit normal liver cells, as expected because ATRA selectively inhibits active Pin1 in cancer cells. Moreover ATRA-PLLA microparticles significantly enhanced the efficacy of ATRA against HCC tumor growth in mice through reducing Pin1, with a better potency than the slow-releasing ATRA formulation, consistent with its improved pharmacokinetic profiles. This study illustrates an effective platform to produce controlled release formulation of anti-cancer drugs, and ATRA-PLLA microparticles might be a promising targeted drug for HCC therapy as PLLA is biocompatible, biodegradable and nontoxic to humans. PMID- 29170141 TI - RNA nanoparticle distribution and clearance in the eye after subconjunctival injection with and without thermosensitive hydrogels. AB - Thermodynamically and chemically stable RNA nanoparticles derived from the three way junction (3WJ) of the pRNA from bacteriophage phi29 DNA packaging motor were examined previously for ocular delivery. It was reported that, after subconjunctival injection, RNA nanoparticles with tri-way shape entered the corneal cells but not the retinal cells, whereas particle with four-way shape entered both corneal and retinal cells. The present study evaluated ocular delivery of RNA nanoparticles with various shapes and sizes, and assessed the effect of thermosensitive hydrogels (poly(lactic-co-glycolic acid)-b poly(ethylene glycol)-b-poly(lactic-co-glycolic acid); PLGA-PEG-PLGA) for increasing the retention of RNA nanoparticles in the eye. Fluorescence imaging of mouse eyes and fluorescence microscopy of dissected eye tissues from the conjunctiva, cornea, retina, and sclera were performed to determine the distribution and clearance of the nanoparticles in the eyes after subconjunctival injection in vivo. RNA nanoparticles entered the cells of the conjunctiva, cornea, retina, and sclera after subconjunctival delivery. The clearance of RNA pentagon was slower than both RNA square and triangle of the same designed edge length (10nm) in the eye, and the clearance of RNA squares of the longer edge lengths (10 and 20nm) was slower than RNA square of the shorter edge length (5nm), thus indicating that the size could affect ocular pharmacokinetics of the nanoparticles. At 24h after the injection, approximately 6-10% of the fluorescence signal from the larger nanoparticles in the study (RNA square of 20nm edge length and RNA pentagon of 10nm edge length) remained in the eye, and up to 70% of the retinal cells contained the nanoparticles. The results suggest that the larger nanoparticles were "gulped" in conjunctival, corneal, retinal, and scleral cells, similar to the behavior observed in macrophages. Additionally, the combination of RNA nanoparticles with the thermosensitive polymers increased the retention of the nanoparticles in the eye.

PMID- 29170142 TI - A robust microparticle platform for a STING-targeted adjuvant that enhances both humoral and cellular immunity during vaccination. AB - Most FDA-approved adjuvants for infectious agents boost humoral but not cellular immunity, and have poorly-understood mechanisms. Stimulator of interferon genes (STING, also known as MITA, MPYS, or ERIS) is an exciting adjuvant target due to its role in cyclic dinucleotide (CDN)-driven anti-viral immunity; however, a major hindrance is STING's cytosolic localization which requires intracellular delivery of its agonists. As a result, STING agonists administered in a soluble form have elicited suboptimal immune responses. Delivery of STING agonists via particle platforms has proven a more successful strategy, but the opportunity for improved formulations and bioactivity remains. In this study we evaluated the adjuvant activity of the potent STING agonist, CDN 3'3'-cGAMP (cGAMP), encapsulated in acid-sensitive acetalated dextran (Ace-DEX) polymeric microparticles (MPs) which passively target antigen-presenting cells for intracellular release. This formulation was superior to all particle delivery systems evaluated and maintained its bioactivity following a sterilizing dose of gamma irradiation. Compared to soluble cGAMP, the Ace-DEX cGAMP MPs enhanced type I interferon responses nearly 1000-fold in vitro and 50-fold in vivo, caused up to a 104-fold boost in antibody titers, increased Th1-associated responses, and expanded germinal center B cells and memory T cells. Furthermore, the encapsulated cGAMP elicited no observable toxicity in animals and achieved protective immunity against a lethal influenza challenge seven months post immunization when using CDN adjuvant doses up to 100-fold lower than previous reports. For these reasons, Ace-DEX MP-encapsulated cGAMP represents a potent vaccine adjuvant of humoral and cellular immunity. PMID- 29170144 TI - Coexistence of tachyarrhythmias in patients with tetralogy of Fallot. AB - BACKGROUND: The expanding population of adult patients with tetralogy of Fallot (ToF) requires knowledge of its long-term sequelae. OBJECTIVE: The purpose of this study was to examine the coexistence and order of appearance of atrial fibrillation (AF), other supraventricular tachycardias (SVTs), ventricular tachycardia (VT), and ventricular fibrillation (VF), and their impact on survival during long-term follow-up. METHODS: Adult, corrected ToF patients [N = 225; 128 male; mean +/- SD (minimum-maximum) age 41 +/- 12 (19-79) years] were included in the study. Medical correspondence, ECGs, and Holter recordings were reviewed for documented AF, other SVTs, VT, and VF. RESULTS: During follow-up of 35 +/- 9 (16 64) years, sustained tachyarrhythmias, including SVT (n=50, 22%), AF (n=29, 13%), VT (n=20, 9%), and VF (n=9, 4%), were observed in 71 patients (32%), of whom 27 (38%) had coexistence of different tachyarrhythmias. In 18 patients with coexisting SVT and AF, SVT most often preceded AF in 13 (72%). Age at SVT onset was similar between those with and those without subsequent AF development (40 +/ 17 years vs 35 +/- 16 years; P = .283). However, age at SVT and AF onset were positively correlated (rho 0.585; P = .011). Prevalence of SVT/AF was associated with VT/VF prevalence (odds ratio [OR] 4.59; P < .001). Although 11% of patients with SVT/AF subsequently develop VT/VF, onset of SVT/AF could not predict future VT/VF development (OR 1.81; P = .233). Adult ToF patients are initially at risk for SVT development, followed by AF, VT, and VF at 46 (43-50), 56 (53-59), 57 (54 61), and 62 (61-63) years after ToF correction (P < .001), respectively. Survival time decreased when sustained tachyarrhythmias developed (P = .024). Age at onset of SVT, AF, and VT was positively correlated with age at death (SVT: rho 0.734; P = .004; AF: rho 0.783; P = .007, VT: rho 0.755; P = .050). CONCLUSION: Coexistence of different (supra)ventricular tachyarrhythmias is frequently observed in adult ToF patients. In these patients, a specific order of these tachyarrhythmias was observed. Tachyarrhythmias are associated with decreased survival time, and, more importantly, age at tachyarrhythmia development positively correlates with age at death. PMID- 29170145 TI - Sharing Family Life Information Through Video Calls and Other Information and Communication Technologies and the Association With Family Well-Being: Population Based Survey. AB - BACKGROUND: The use of information and communication technologies (ICTs) for information sharing among family members is increasing dramatically. However, little is known about the associated factors and the influence on family well being. OBJECTIVE: The authors investigated the pattern and social determinants of family life information sharing with family and the associations of different methods of sharing with perceived family health, happiness, and harmony (3Hs) in Hong Kong, where mobile phone ownership and Internet access are among the most prevalent, easiest, and fastest in the world. METHODS: A territory-wide population-based telephone survey was conducted from January to August 2016 on different methods of family life information (ie, information related to family communication, relationships with family members, emotion and stress management) sharing with family members, including face-to-face, phone, instant messaging (IM), social media sites, video calls, and email. Family well-being was assessed by three single items on perceived family health, happiness, and harmony, with higher scores indicating better family well-being. Adjusted prevalence ratios were used to assess the associations of sociodemographic factors with family life information sharing, and adjusted beta coefficients for family well-being. RESULTS: Of 2017 respondents, face-to-face was the most common method to share family life information (74.45%, 1502/2017), followed by IM (40.86%, 824/2017), phone (28.10%, 567/2017), social media sites (11.91%, 240/2017), video calls (5.89%, 119/2017), and email (5.48%, 111/2017). Younger age and higher education were associated with the use of any (at least one) method, face-to-face, IM, and social media sites for sharing family life information (all P for trend <.01). Higher education was most strongly associated with the use of video calls (adjusted prevalence ratio=5.61, 95% CI 2.29-13.74). Higher household income was significantly associated with the use of any method, face-to-face, and IM (all P for trend <.05). Sharing family life information was associated with a higher level of perceived family well-being (beta=0.56, 95% CI 0.37-0.75), especially by face-to-face (beta=0.62, 95% CI 0.45-0.80) and video calls (beta=0.34, 95% CI 0.04-0.65). The combination of face-to-face and video calls was most strongly associated with a higher level of perceived family well-being (beta=0.81, 95% CI 0.45-1.16). CONCLUSIONS: The differential use of ICTs to share family life information was observed. The prevalence of video calls was low, but associated with much better family well-being. The results need to be confirmed by prospective and intervention studies to promote the use of video calls to communicate and share information with family, particularly in disadvantaged groups. PMID- 29170146 TI - An eHealth Intervention to Promote Physical Activity and Social Network of Single, Chronically Impaired Older Adults: Adaptation of an Existing Intervention Using Intervention Mapping. AB - BACKGROUND: Especially for single older adults with chronic diseases, physical inactivity and a poor social network are regarded as serious threats to their health and independence. The Active Plus intervention is an automated computer tailored eHealth intervention that has been proven effective to promote physical activity (PA) in the general population of adults older than 50 years. OBJECTIVE: The aim of this study was to report on the methods and results of the systematic adaptation of Active Plus to the wishes and needs of the subgroup of single people older than 65 years who have one or more chronic diseases, as this specific target population may encounter specific challenges regarding PA and social network. METHODS: The Intervention Mapping (IM) protocol was used to systematically adapt the existing intervention to optimally suit this specific target population. A literature study was performed, and quantitative as well as qualitative data were derived from health care professionals (by questionnaires, n=10) and the target population (by focus group interviews, n=14), which were then systematically integrated into the adapted intervention. RESULTS: As the health problems and the targeted behavior are largely the same in the original and adapted intervention, the outcome of the needs assessment was that the performance objectives remained the same. As found in the literature study and in data derived from health professionals and focus groups, the relative importance and operationalization of the relevant psychosocial determinants related to these objectives are different from the original intervention, resulting in a refinement of the change objectives to optimally fit the specific target population. This refinement also resulted in changes in the practical applications, program components, intervention materials, and the evaluation and implementation strategy for the subgroup of single, chronically impaired older adults. CONCLUSIONS: This study demonstrates that the adaptation of an existing intervention is an intensive process in which adopting the IM protocol is an invaluable tool. The study provides a broad insight in adapting interventions aimed at single older adults with a chronic disease. It is concluded that even when the new target population is a sizable segment of the original target population, the adapted intervention still needs considerable changes to optimally fit the needs and situational differences of the narrower target population. PMID- 29170147 TI - Bioimpedance Alerts from Cardiovascular Implantable Electronic Devices: Observational Study of Diagnostic Relevance and Clinical Outcomes. AB - BACKGROUND: The use of implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy (CRT) devices is expanding in the treatment of heart failure. Most of the current devices are equipped with remote monitoring functions, including bioimpedance for fluid status monitoring. The question remains whether bioimpedance measurements positively impact clinical outcome. OBJECTIVE: The aim of this study was to provide a comprehensive overview of the clinical interventions taken based on remote bioimpedance monitoring alerts and their impact on clinical outcome. METHODS: This is a single-center observational study of consecutive ICD and CRT patients (n=282) participating in protocol driven remote follow-up. Bioimpedance alerts were analyzed with subsequently triggered interventions. RESULTS: A total of 55.0% (155/282) of patients had an ICD or CRT device equipped with a remote bioimpedance algorithm. During 34 (SD 12) months of follow-up, 1751 remote monitoring alarm notifications were received (2.2 per patient-year of follow-up), comprising 2096 unique alerts (2.6 per patient-year of follow-up). Since 591 (28.2%) of all incoming alerts were bioimpedance-related, patients with an ICD or CRT including a bioimpedance algorithm had significantly more alerts (3.4 versus 1.8 alerts per patient-year of follow-up, P<.001). Bioimpedance-only alerts resulted in a phone contact in 91.0% (498/547) of cases, which triggered an actual intervention in 15.9% (87/547) of cases, since in 75.1% (411/547) of cases reenforcing heart failure education sufficed. Overall survival was lower in patients with a cardiovascular implantable electronic device with a bioimpedance algorithm; however, this difference was driven by differences in baseline characteristics (adjusted hazard ratio of 2.118, 95% CI 0.845-5.791). No significant differences between both groups were observed in terms of the number of follow-up visits in the outpatient heart failure clinic, the number of hospital admissions with a primary diagnosis of heart failure, or mean length of hospital stay. CONCLUSIONS: Bioimpedance-only alerts constituted a substantial amount of incoming alerts when turned on during remote follow-up and triggered an additional intervention in only 16% of cases since in 75% of cases, providing general heart failure education sufficed. The high frequency of heart failure education that was provided could have contributed to fewer heart failure-related hospitalizations despite significant differences in baseline characteristics. PMID- 29170149 TI - GP returners: then and now. PMID- 29170148 TI - A Group of 500 Women Whose Health May Depart Notably From the Norm: Protocol for a Cross-Sectional Survey. AB - BACKGROUND: Longitudinal studies of women's health often seek to identify predictors of good health. Research has shown that following simple guidelines can halve women's mortality. The ongoing Australian Longitudinal Study of Women's Health (ALSWH) shows that Australian women are getting better at reducing their smoking and alcohol use, and are generally diligent about attending recommended health screenings, but are becoming less successful at dealing with obesity. There are communities of women who live unusually healthy lives (Rosetans, Seventh-Day Adventists, traditional Japanese women), but their lifestyles are unlikely to be adopted widely. Universal Medicine (UM) is a complementary-to medicine approach that emphasizes personal empowerment and the importance of menstrual health symptoms. OBJECTIVE: This survey investigates whether the approximately 500 women associated with UM exhibit health status significantly above the norm. As part of this investigation, questions for a newly developed menstrual attitudes questionnaire will also be evaluated. METHODS: A quantitative cross-sectional survey of women in a UM cohort was designed with the help of three focus groups of women at three life stages: in menses, peri-menopausal, and menopausal. The menstrual attitudes portion of the survey incorporates the insights of these women regarding female health issues. The survey also includes 41 questions taken from the ALSWH. Focus groups generated additional questions about symptoms experienced and attitudes toward female health issues. ALSWH questions, including a range of health scales like the Short Form 36 (SF-36), Center for Epidemiologic Studies Depression Scale, Perceived Control Scale, Kessler Psychological Distress Scale, and the Multi-Item Summed Score for Perceived Stress, along with questions about experienced major health events, were investigated and incorporated if considered suitable. RESULTS: The validity of the menstrual attitudes questionnaire will be evaluated with Cohen's kappa. ALSWH respondents and UM participants will be compared, using unweighted regression or regression weighted or normalized by age, education, and interest in alternative treatments (to increase comparability), as appropriate. Analyses will determine whether UM-related variables (being a UM participant, length of UM participation, number of UM events attended) are associated with: differences in the number of major health events and health symptoms experienced; SF-36 physical and mental health scores; body mass index; and consumption of alcohol, tobacco, sugar, salt, caffeine, and dairy. CONCLUSIONS: If women in the UM cohort are truly in substantially better health than the norm, further investigations may be worthwhile to see whether UM plays a causal role, and whether the women's practices are generalizable.

AB - BACKGROUND: YouTube's online archive of video testimonials related to health information are more commonly viewed than those developed by clinicians and professional groups, suggesting the importance of the patient experience to viewers. We specifically sought to examine the accuracy of information on, and projected acceptability of, the intrauterine device (IUD) from these YouTube testimonials. METHODS: We searched YouTube for videos about individual uploaders' IUD experiences, using the search terms 'intrauterine device', 'IUD', 'Mirena' and 'Paragard'. Given interest in user testimonials, we excluded professional and instructional videos belonging to commercial or non-profit entities. Two reviewers independently analysed the videos using a structured guide, with attention to inaccurate information. RESULTS: Of 86 identified videos, four videos featured clinicians and were excluded; 62 met inclusion criteria. Interrater agreement on IUD portrayal was good (K=0.73). Young (mean age 25, range 19-38, years), white (75%), nulliparous (61%) women primarily uploaded content. Most described placement of the LNG-IUS (65%), were posted within 1 month of insertion (45%), and mentioned side effects (66%) - bleeding, pain, and partner sensation of the strings. About one-third of videos contained inaccurate information (34%) and were thought to project an overall negative experience (30%). Videos portraying IUDs negatively were associated with inaccurate information and/or mention of side effects. CONCLUSION: While one-third of IUD user testimonials on YouTube contained inaccurate information, the majority of IUD experiences were perceived by our study viewers to be positive.

PMID- 29170152 TI - Impact of Lipid Measurements in Youth in Addition to Conventional Clinic-Based Risk Factors on Predicting Preclinical Atherosclerosis in Adulthood: International Childhood Cardiovascular Cohort Consortium. AB - BACKGROUND: Data suggest that the prediction of adult cardiovascular disease using a model comprised entirely of adult nonlaboratory-based risk factors is equivalent to an approach that additionally incorporates adult lipid measures. We assessed and compared the utility of a risk model based solely on nonlaboratory risk factors in adolescence versus a lipid model based on nonlaboratory risk factors plus lipids for predicting high-risk carotid intima-media thickness (cIMT) in adulthood. METHODS: The study comprised 2893 participants 12 to 18 years of age from 4 longitudinal cohort studies from the United States (Bogalusa Heart Study and the Insulin Study), Australia (Childhood Determinants of Adult Health Study), and Finland (The Cardiovascular Risk in Young Finns Study) and followed into adulthood when cIMT was measured (mean follow-up, 23.4 years). Overweight status was defined according to the Cole classification. Hypertension was defined according to the Fourth Report on High Blood Pressure in Children and Adolescents from the National High Blood Pressure Education Program. High-risk plasma lipid levels were defined according to the National Cholesterol Education Program Expert Panel on Cholesterol Levels in Children. High cIMT was defined as a study-specific value >=90th percentile. Age and sex were included in each model. RESULTS: In univariate models, all risk factors except for borderline high and high triglycerides in adolescence were associated with high cIMT in adulthood. In multivariable models (relative risk [95% confidence interval]), male sex (2.7 [2.0-2.6]), prehypertension (1.4 [1.0-1.9]), hypertension (1.9 [1.3 2.9]), overweight (2.0 [1.4-2.9]), obesity (3.7 [2.0-7.0]), borderline high low density lipoprotein cholesterol (1.6 [1.2-2.2]), high low-density lipoprotein cholesterol (1.6 [1.1-2.1]), and borderline low high-density lipoprotein cholesterol (1.4 [1.0-1.8]) remained significant predictors of high cIMT (P<0.05). The addition of lipids into the nonlaboratory risk model slightly but significantly improved discrimination in predicting high cIMT compared with nonlaboratory-based risk factors only (C statistics for laboratory-based model 0.717 [95% confidence interval, 0.685-0.748] and for nonlaboratory 0.698 [95% confidence interval, 0.667-0.731]; P=0.02). CONCLUSIONS: Nonlaboratory-based risk factors and lipids measured in adolescence independently predicted preclinical atherosclerosis in young adulthood. The addition of lipid measurements to traditional clinic-based risk factor assessment provided a statistically significant but clinically modest improvement on adolescent prediction of high cIMT in adulthood.

Here, we used a mouse model (crrm1) that expresses a reduced level of the RyR2 protein to determine the impact of reduced RyR2 protein expression on the susceptibility to VT, cardiac alternans, cardiac hypertrophy, and sudden death. Electrocardiographic analysis revealed that after the injection of relatively high doses of caffeine and epinephrine (agents commonly used for stress test), wild-type (WT) mice displayed long-lasting VTs, whereas the crrm1 mutant mice exhibited no VTs at all, indicating that the crrm1 mutant mice are resistant to stress-induced VTs. Intact heart Ca2+ imaging and action potential (AP) recordings showed that the crrm1 mutant mice are more susceptible to fast-pacing induced Ca2+ alternans and AP duration alternans compared with WT mice. The crrm1 mutant mice also showed an increased heart-to-body-weight ratio and incidence of sudden death at young ages. Furthermore, the crrm1 mutant hearts displayed altered Ca2+ transients with increased time-to-peak and decay time (T50), increased ventricular wall thickness and ventricular cell area compared with WT hearts. These results indicate that reduced RyR2 protein expression suppresses stress-induced VTs, but enhances the susceptibility to cardiac alternans, hypertrophy, and sudden death. PMID- 29170160 TI - Insulin selectively reduces mitochondrial uncoupling in brown adipose tissue in mice. AB - The purpose of the present study was to determine the effects of prolonged hyperinsulinemia on mitochondrial respiration and uncoupling in distinct adipose tissue depots. Sixteen-week-old male mice were injected daily with placebo or insulin to induce an artificial hyperinsulinemia for 28 days. Following the treatment period, mitochondrial respiration and degree of uncoupling were determined in permeabilized perirenal, inguinal, and interscapular adipose tissue. White adipose tissue (WAT) mitochondria (inguinal and perirenal) respire at substantially lower rates compared with brown adipose tissue (BAT). Insulin treatment resulted in a significant reduction in mitochondrial respiration in inguinal WAT (iWAT) and interscapular BAT (iBAT), but not in perirenal WAT (pWAT). Furthermore, these changes were accompanied by an insulin-induced reduction in UCP-1 (uncoupling protein 1) and PGC-1alpha in iWAT and iBAT only, but not in pWAT or skeletal muscle. Compared with adipose tissue mitochondria in placebo conditions, adipose tissue from hyperinsulinemic mice manifested a site specific reduction in mitochondrial respiration probably as a result of reduced uncoupling. These results may help explain weight gain so commonly seen with insulin treatment in type 2 diabetes mellitus. PMID- 29170162 TI - Classification of gastrointestinal stromal tumor syndromes. AB - Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, thought to derive from neoplastic outgrowth of the interstitial cells of Cajal. Building on recent advances in recognition, classification and diagnosis, the past two decades have seen a changing paradigm with molecular diagnostics and targeted therapies. KIT and PDGFRA mutations account for 85-90% of GIST carcinogenesis. However, the remaining 10-15% of GISTs, which until recently were called KIT/PDGFRA wild-type GISTs, have been found to have one of the several mutations, including in the SDHA, B, C, D, BRAF and NF1 genes. Though most of such GISTs are sporadic, a number of families with high incidence rates of GISTs and other associated clinical manifestations have been reported and found to harbor germline mutations in KIT, PDGFRA, SDH subunits and NF1 The goal of this review is to describe the mutations, clinical manifestations and therapeutic implications of syndromic and inherited GISTs in light of recent studies of their clinicopathologic range and pathogenesis.

PMID- 29170163 TI - MicroRNAs: tiny molecules with a significant role in mammalian follicular and oocyte development. AB - The genetic regulation of female fertility (follicular development, oocyte maturation and early preimplantation embryo development) involves the spatio temporal regulation of those genes that play key roles in various stages of the female reproductive axis. MicroRNAs (miRNAs), a class of small non-coding RNAs, are known to regulate the expression of a large proportion of such genes. In recent decades, multiple studies have aimed to determine the roles of these non coding RNAs in mammalian follicular development, oocyte growth and embryo development. These studies have applied a variety of approaches, including conditional knockout of miRNA biogenesis genes, high-throughput sequencing technologies for pattern recognition in miRNA expression and loss- and gain-of function of miRNAs in various animal models. In addition to the cellular miRNAs, a large variety of RNAs are found in circulation, being coupled with extracellular vesicles, proteins and lipids. Because of their potential as diagnostic markers for abnormal physiologies, there is increasing interest in the identification of extracellular miRNAs in various biological fluids and spent in vitro culture media. This review focuses on studies addressing the expression and potential role of cellular and extracellular miRNAs in mammalian follicular cell physiology and subsequent ovarian functionality and oocyte maturation.

PMID- 29170164 TI - KIRREL is differentially expressed in adipose tissue from 'fertil+' and 'fertil-' cows: in vitro role in ovary? AB - We have previously shown that dairy cows carrying the 'fertil-' haplotype for one quantitative trait locus affecting female fertility located on the bovine chromosome three (QTL-F-Fert-BTA3) have a significantly lower conception rate and body weight after calving than cows carrying the 'fertil+' haplotype. Here, we compared by Tiling Array the expression of genes included in the QTL-F-Fert-BTA3 in 'fertil+' and 'fertil-' adipose tissue one week after calving when plasma non esterified fatty acid concentrations were greater in 'fertil-' animals. We observed that thirty-one genes were overexpressed whereas twelve were under expressed in 'fertil+' as compared to 'fertil-' cows (P < 0.05). By quantitative PCR and immunoblot we confirmed that adipose tissue KIRREL mRNA and protein were significantly greater expressed in 'fertil+' than in 'fertil-'. KIRREL mRNA is abundant in bovine kidney, adipose tissue, pituitary, and ovary and detectable in hypothalamus and mammary gland. Its expression (mRNA and protein) is greater in kidney of 'fertil+' than 'fertil-' cows (P < 0.05). KIRREL (mRNA and protein) is also present in the different ovarian cells with a greater expression in granulosa cells of 'fertil+' than 'fertil-' cows. In cultured granulosa cells, recombinant KIRREL halved steroid secretion in basal state (P < 0.05). It also decreased cell proliferation (P < 0.05) and in vitro oocyte maturation (P < 0.05). These results were associated to a rapid increase in MAPK1/3 and MAPK14 phosphorylation in granulosa cells and to a decrease in MAPK1/3 phosphorylation in oocyte. Thus, KIRREL could be a potential metabolic messenger linking body composition and fertility. PMID- 29170168 TI - Revealing the complexity of quitting smoking: a qualitative grounded theory study of the natural history of quitting in Australian ex-smokers. AB - OBJECTIVE: To explore the quitting histories of Australian ex-smokers in order to develop an understanding of the varied contribution of smoking cessation assistance (either pharmacotherapy or professionally mediated behavioural support) to the process of quitting. DESIGN: Qualitative grounded theory study; in-depth interviews. PARTICIPANTS: 37 Australian adult ex-smokers (24-68 years; 15 men, 22 women) who quit in the past 6-24 months. RESULTS: Although participants' individual quitting histories and their overall experiences of quitting were unique, when the 37 quitting histories were compared it was clear two experiences were common to almost all participants: almost no one quit at their first quit attempt and almost everyone started out quitting unassisted. Furthermore, distinct patterns existed in the timing and use of assistance, in particular the age at which assistance was first used, how some participants were resolutely uninterested in assistance, and how assistance might have contributed to the process of successful quitting even if not used on the final quit attempt. Importantly, three patterns in use of assistance were identified: (1) only ever tried to quit unassisted (n=13); (2) started unassisted, tried assistance but reverted back to unassisted (n=13); (3) started unassisted, tried assistance and quit with assistance (n=11). For most participants, insight into what quitting would require was only gained through prior quitting experiences with and without assistance. For a number of participants, interest in assistance was at its lowest when the participant was most ready to quit. CONCLUSION: Quitting should be viewed as a process drawing on elements of assisted and unassisted quitting rather than a stand-alone event that can be labelled as strictly assisted or unassisted.

AB - INTRODUCTION: Several studies suggest that the health of an individual is influenced by the socioeconomic status (SES) of the community in which he or she lives. This analysis seeks to understand the relationship between SES, tobacco store density and health outcomes at the neighbourhood level in a large urban community. METHODS: Data from the 55 neighbourhoods of Baltimore City were reviewed and parametric tests compared demographics and health outcomes for low income and high-income neighbourhoods, defined by the 50th percentile in median household income. Summary statistics are expressed as median. Tobacco store density was evaluated as both an outcome and a predictor. Association between tobacco store densities and health outcomes was determined using Moran's I and spatial regression analyses to account for autocorrelation. RESULTS: Compared with higher-income neighbourhoods, lower-income neighbourhoods had higher tobacco store densities (30.5 vs 16.5 stores per 10 000 persons, P=0.01), lower life expectancy (68.5 vs 74.9 years, P<0.001) and higher age-adjusted mortality (130.8 vs 102.1 deaths per 10 000 persons, P<0.001), even when controlling for other store densities, median household income, race, education status and age of residents. CONCLUSION: In Baltimore City, median household income is inversely associated with tobacco store density, indicating poorer neighbourhoods in Baltimore City have greater accessibility to tobacco. Additionally, tobacco store density was linked to lower life expectancy, which underscores the necessity for interventions to reduce tobacco store densities. PMID- 29170169 TI - Thoracic aortic transection resulting in a type B dissection following blunt trauma. AB - A 39-year-old man sustained an acute grade III aortic injury resulting in a type B aortic dissection in the setting of severe traumatic brain injury, cervical spine injury and multiple orthopaedic injuries following a motorcycle crash. The patient underwent an emergent thoracic endovascular aortic repair, complicated by a thoracic pseudoaneurysm rupture and ongoing exsanguination from a persistent type 1 endoleak. Additional stent grafts were required to gain control of the endoleak. The patient ultimately progressed to brain death post procedure in the intensive care unit. This case reviews treatment considerations in the context of a blunt thoracic aortic transection and distal dissection with concomitant polytrauma. PMID- 29170170 TI - Twist on a classic: vitamin D and hypercalcaemia of malignancy. AB - Malignancy is the most common cause of hypercalcaemia in the inpatient setting. Most cases are caused by tumour production of parathyroid hormone-related protein and osseous metastases. In less than 1% of cases, hypercalcaemia is driven by increased production of 1,25-dihydroxyvitamin D (1,25(OH)2D), a mechanism most commonly seen in haematological malignancies. Here, we describe a woman with metastatic small cell cervical carcinoma who developed hypercalcaemia secondary to paraneoplastic overproduction of 1,25(OH)2D, a finding that, to our knowledge, has not been previously associated with this cancer. We also review the current cases of solid tumours reported to have this mechanism of hypercalcaemia and the evidence behind multiple therapeutic approaches.

Dental implant rehabilitation might become necessary to overcome the functional and psychological adverse effects of LAD periodontitis, especially in patients with milder forms who are expected to have a relatively normal life expectancy. Outcome of dental implants in patients with LAD has not been previously reported; we describe the dental rehabilitation of a 24-year-old man with clinical features of LAD using endosseous dental implants.

AB - We present the case of a 28-year-old man who presented with chest pain and elevated cardiac biomarkers, with no evidence of acute ischaemia. He had a pronounced eosinophilia, abnormal echocardiographic, cardiac MRI and CT findings. He underwent transbronchial biopsy of carinal lymph nodes and of lung parenchyma. Endomyocardial biopsy yielded an eosinophilic infiltrate. He was treated with high dose glucocorticoids and made a rapid recovery. Testing for FIP1L1-PDGFRA and other BCR-ABL1 mutations was negative. Ultimately, he was diagnosed with eosinophilic granulomatosis with polyangiitis, also known as Churg-Strauss syndrome. PMID- 29170173 TI - Kikuchi-Fujimoto disease: an unusual presentation of meningitis in a returning traveller. AB - A 19-year-old, previously healthy woman developed a pruritic erythematous maculopapular rash on her bilateral palms and wrists, right-sided tender cervical lymphadenopathy and nightly fevers and headaches 5 days after returning from a 1 month trip to Cambodia. She presented 2 weeks after her trip due to ongoing nightly fevers to a maximum of 38.8 degrees C. She was given empiric doxycycline for possible rickettsial disease, though an extensive infectious workup returned without positive findings. Lumbar puncture was performed on hospital day 4, and spinal fluid analysis was consistent with aseptic meningitis. On hospital day 5, core biopsy and fine-needle aspiration were performed on the largest anterior cervical lymph node. Her fever curve gradually improved, and she was discharged on hospital day 6. Results of the lymph node biopsy were finalized 5 days after discharge and were compatible with Kikuchi's lymphadenitis. Symptoms had completely resolved on follow-up with infectious disease and rheumatology. PMID- 29170174 TI - Wernicke's encephalopathy secondary to gestational hyperthyroidism.

AB - We report a likely false-positive phencyclidine (PCP) result detected with a urine drug screen (UDS) (Medtox, St Paul, Minnesota, USA) in the setting of therapeutic desvenlafaxine (Pristiq) use. Desvenlafaxine (O-desmethylvenlafaxine) is the active metabolite of venlafaxine (Effexor). Prior reports have confirmed venlafaxine use resulting in a false-positive for PCP on a UDS. However, there has been a paucity of reporting of commercially available desvenlafaxine formulations (Pristiq, Khedezla) resulting in false-positives for PCP on a UDS. PMID- 29170179 TI - ANCA-positive IgA nephropathy without necrotising or crescentic glomerulonephritis: a clinical conundrum. AB - IgA nephropathy, the most prevalent form of primary glomerular disease, usually portends a favourable outcome. Antineutrophil cytoplasmic autoantibodies (ANCAs) have been reported in association with IgA nephropathy in a small subset of patients, mostly presenting with rapidly progressive glomerulonephritis and necrotising crescentic lesions. Herein, we describe a case of IgA nephropathy, positive serum cytoplasmic and perinuclear ANCAs with anti-myeloperoxidase antibody, and preserved renal function without any histological evidence of necrotising or crescentic glomerulonephritis. Based on available mechanistic and clinical data, we opine that such patients could benefit from close monitoring of renal function. PMID- 29170180 TI - Muscle fasciculation detected by ECG. AB - A 79-year-old man presented to hospital with scald burns to the perineum after a syncopal episode while in a hot bathtub. Admission ECG was misdiagnosed as possible ventricular fibrillation with high-frequency irregular waveforms in lead V2 at a rate exceeding 1000 cycles per minute, corresponding to intervening skeletal muscle contractions unrelated to the heart. Follow-up ECG showed full resolution of the irregular waveforms. Muscle fasciculations are a benign cause of ECG artefact and can easily be mistaken for serious cardiac arrhythmias. While most muscle fasciculations detected on ECG are benign, in the correct clinical circumstance these waveforms indicate an underlying neuromuscular disorder. The patient underwent surgical skin grafting with no perioperative cardiac complications and no further syncope in hospital. PMID- 29170181 TI - Multiple hybrid sutures of bucket handle injury on the lateral and medial meniscus of the knee. AB - The objective of the study is to show possibilities of several combinations of suture techniques in a rare bicompartmental bucket handle injury. According to specific injury characteristics, combined suturing techniques were used. The option for different meniscal suture techniques in the two knee compartments allowed the patient, after completing the treatment, to return to his activities with a preserved meniscus. Although meniscectomy continues to be a chosen technique in bucket handle injury, we attempted to show a case of bicompartmental meniscal suture with different techniques. In this, which could be a case of rapid resolution and quick return to activities with bicompartmental meniscectomy, we chose to preserve the menisci with more complex techniques and longer rehabilitation, believing that the preservation of this structure could be extremely valuable in the long term. PMID- 29170182 TI - Panuveitis simulating ocular Behcet's in cases of chronic myelogenous leukaemia in remission. AB - We report two patients with chronic myelogenous leukaemia (CML) in remission phase who developed panuveitis simulating Behcet's disease. A 26-year-old man presented with bilateral panuveitis (hypopyon in the right eye, bilateral anterior segment inflammation, vitritis and retinitis). He was on imatinib for CML which was in remission. He gave a history of recurrent oral ulcers. The panuveitis responded to oral and topical steroids but recurred after the steroids were stopped. His ocular condition again stabilised on restarting oral steroids and azathioprine. The second patient, a 28-year-old man, presented with bilateral anterior segment inflammation, vitritis, exudative retinal detachment and hypopyon in the right eye. He was also on imatinib with the CML being in remission. The uveitis and exudative retinal detachment improved on systemic and topical steroids. The vision of this patient did not improve as optic atrophy ensued. The panuveitis seen in our patients with CML responded favourably to oral steroids/immunosuppressant therapy.

AB - Round ligament tumours represent a rare entity that can present similarly to an incarcerated hernia. Basic understanding and appropriate preoperative management is imperative in order to differentiate between the two diagnoses. Leiomyoma is the most common type of round ligament tumour. It is associated with oestrogen exposure and is more common in the presence of uterine leiomyomas. Here we discuss a 68-year-old woman who presented with a palpable left inguinal mass that progressively grew in size, associated with pelvic pressure and discomfort. On surgical resection, the mass was found to be derived from the round ligament at the entrance of the external inguinal ring. Pathology confirmed a round ligament leiomyoma, measuring 25*9*8.5 cm. This case is the largest round ligament leiomyoma recorded to date and the first to exhibit carneous degeneration. A review of the current literature is also provided. PMID- 29170185 TI - Dysosmia and dysgeusia associated with duloxetine. AB - Common adverse effects of serotonin-norepinephrine reuptake inhibitors are nausea, dry mouth, dizziness and headache. We describe the case of a patient with dysosmia and subsequent dysgeusia associated with duloxetine. A 68-year-old Japanese woman with a history of type 1 diabetes mellitus, hypertension, insomnia and reflux esophagitis presented to a local hospital with bilateral leg pain; she was treated with duloxetine. However, after 4 weeks, she sensed rotten egg smell, experienced nausea and vomiting and was admitted to our hospital. We diagnosed dysosmia using the T&T olfactometer threshold test and dysgeusia using filter paper disk method. Taste was assessed using electrogustometry. We suspected that dysosmia and dysgeusia were adverse effects of duloxetine. After stopping duloxetine, her symptoms gradually subsided and the above test results improved, despite continuing the other ongoing medication. To the best of our knowledge, this is the first case report of dysosmia and dysgeusia associated with duloxetine.

History revealed the patient had a past episode of infective keratitis managed medically in a local hospital. The last follow-up record suggested a diagnosis of healed keratitis with corneoiridic scar. On examination, the patient had visual acuity of hand movement and a corneoiridic scar of 7*7 mm with an inferotemporal translucent cystic area measuring 3*4 mm in size with underlying uveal tissue visible. Seidel test was found to be positive confirming leakage. For this, a tenon patch over the area of defect along with anterior chamber formation was done. On postoperative day 1, the graft was well attached and anterior chamber was formed with no leak on Seidel test. Intraocular pressure was 16 mm Hg.

AB - OBJECTIVES: To examine the extent and cost of work disability among patients with gout compared with matched population controls and to analyse predictors of work disability. METHODS: A regional cohort study using data from Swedish national and regional registries from January 2000 through December 2012, including 4571 patients with gout of working age, with a first recorded diagnosis of gout in the years 2003-2009 and 22 482 population controls, matched by age, sex and place of residence. Differences in baseline characteristics (educational level, income, previous employment and comorbidities) and the number of work-loss days (absenteeism) due to sick leave and disability pension for 3 years after identification were calculated. Predictors for new-onset work absenteeism (>90 days/year) in a subset were determined by conditional logistic regression. RESULTS: Patients with gout (median age 53 years) had significantly more comorbidities, lower income and lower level of education than matched controls. The average work absentee rate during the 3-year follow-up period was higher among patients with gout than controls, 22% and 14%, respectively (P<0.0001). New onset absenteeism was in multivariate analyses significantly predicted by gout (OR 1.47; 95% CI 1.23 to 1.75). Other variables independently related to new onset absenteeism were education <=12 years, previous unemployment and history of sick leave, in addition to several comorbidities (renal disease, cardiovascular disease, alcohol abuse and obesity). CONCLUSIONS: Gout is associated with substantially higher work absenteeism and costs for society due to productivity loss, after adjusting for associated comorbidities and socioeconomic differences. Whether more intensive treatment of gout is cost-effective needs to be addressed in future studies.

AB - Kim et al (Reports, 28 April 2017, p. 430) describe a method for harvesting water from air, using a metal-organic framework (MOF) as the adsorbent. The process as described in the paper is, however, inadequate, and the system cannot deliver the claimed amount of liquid water in an arid climate. A modification of the process design and the use of more suitable MOFs may be more likely to achieve the goals targeted by Kim et al.

PMID- 29170203 TI - Identification of a novel locus on chromosome 2q13, which predisposes to clinical vertebral fractures independently of bone density. AB - OBJECTIVES: To identify genetic determinants of susceptibility to clinical vertebral fractures, which is an important complication of osteoporosis. METHODS: Here we conduct a genome-wide association study in 1553 postmenopausal women with clinical vertebral fractures and 4340 controls, with a two-stage replication involving 1028 cases and 3762 controls. Potentially causal variants were identified using expression quantitative trait loci (eQTL) data from transiliac bone biopsies and bioinformatic studies. RESULTS: A locus tagged by rs10190845 was identified on chromosome 2q13, which was significantly associated with clinical vertebral fracture (P=1.04*10-9) with a large effect size (OR 1.74, 95% CI 1.06 to 2.6). Bioinformatic analysis of this locus identified several potentially functional SNPs that are associated with expression of the positional candidate genes TTL (tubulin tyrosine ligase) and SLC20A1 (solute carrier family 20 member 1). Three other suggestive loci were identified on chromosomes 1p31, 11q12 and 15q11. All these loci were novel and had not previously been associated with bone mineral density or clinical fractures. CONCLUSION: We have identified a novel genetic variant that is associated with clinical vertebral fractures by mechanisms that are independent of BMD. Further studies are now in progress to validate this association and evaluate the underlying mechanism. PMID- 29170206 TI - Structural insights into ion conduction by channelrhodopsin 2. AB - The light-gated ion channel channelrhodopsin 2 (ChR2) from Chlamydomonas reinhardtii is a major optogenetic tool. Photon absorption starts a well characterized photocycle, but the structural basis for the regulation of channel opening remains unclear. We present high-resolution structures of ChR2 and the C128T mutant, which has a markedly increased open-state lifetime. The structure reveals two cavities on the intracellular side and two cavities on the extracellular side. They are connected by extended hydrogen-bonding networks involving water molecules and side-chain residues. Central is the retinal Schiff base that controls and synchronizes three gates that separate the cavities. Separate from this network is the DC gate that comprises a water-mediated bond between C128 and D156 and interacts directly with the retinal Schiff base. Comparison with the C128T structure reveals a direct connection of the DC gate to the central gate and suggests how the gating mechanism is affected by subtle tuning of the Schiff base's interactions.

After seeing an agent attain two goals equally often at varying costs, infants expected the agent to prefer the goal it attained through costlier actions. These expectations held across three experiments that conveyed cost through different physical path features (height, width, and incline angle), suggesting that an abstract variable-such as "force," "work," or "effort" supported infants' inferences. We modeled infants' expectations as Bayesian inferences over utility-theoretic calculations, providing a bridge to recent quantitative accounts of action understanding in older children and adults. PMID- 29170231 TI - Structure-property relationships from universal signatures of plasticity in disordered solids. AB - When deformed beyond their elastic limits, crystalline solids flow plastically via particle rearrangements localized around structural defects. Disordered solids also flow, but without obvious structural defects. We link structure to plasticity in disordered solids via a microscopic structural quantity, "softness," designed by machine learning to be maximally predictive of rearrangements. Experimental results and computations enabled us to measure the spatial correlations and strain response of softness, as well as two measures of plasticity: the size of rearrangements and the yield strain. All four quantities maintained remarkable commonality in their values for disordered packings of objects ranging from atoms to grains, spanning seven orders of magnitude in diameter and 13 orders of magnitude in elastic modulus. These commonalities link the spatial correlations and strain response of softness to rearrangement size and yield strain, respectively. PMID- 29170233 TI - The fundamental advantages of temporal networks. AB - Most networked systems of scientific interest are characterized by temporal links, meaning the network's structure changes over time. Link temporality has been shown to hinder many dynamical processes, from information spreading to accessibility, by disrupting network paths. Considering the ubiquity of temporal networks in nature, we ask: Are there any advantages of the networks' temporality? We use an analytical framework to show that temporal networks can, compared to their static counterparts, reach controllability faster, demand orders of magnitude less control energy, and have control trajectories, that are considerably more compact than those characterizing static networks. Thus, temporality ensures a degree of flexibility that would be unattainable in static networks, enhancing our ability to control them. PMID- 29170230 TI - Molecular and cellular reorganization of neural circuits in the human lineage. AB - To better understand the molecular and cellular differences in brain organization between human and nonhuman primates, we performed transcriptome sequencing of 16 regions of adult human, chimpanzee, and macaque brains. Integration with human single-cell transcriptomic data revealed global, regional, and cell-type-specific species expression differences in genes representing distinct functional categories. We validated and further characterized the human specificity of genes enriched in distinct cell types through histological and functional analyses, including rare subpallial-derived interneurons expressing dopamine biosynthesis genes enriched in the human striatum and absent in the nonhuman African ape neocortex. Our integrated analysis of the generated data revealed diverse molecular and cellular features of the phylogenetic reorganization of the human brain across multiple levels, with relevance for brain function and disease. PMID- 29170234 TI - Major role of nitrite-oxidizing bacteria in dark ocean carbon fixation. AB - Carbon fixation by chemoautotrophic microorganisms in the dark ocean has a major impact on global carbon cycling and ecological relationships in the ocean's interior, but the relevant taxa and energy sources remain enigmatic. We show evidence that nitrite-oxidizing bacteria affiliated with the Nitrospinae phylum are important in dark ocean chemoautotrophy. Single-cell genomics and community metagenomics revealed that Nitrospinae are the most abundant and globally distributed nitrite-oxidizing bacteria in the ocean. Metaproteomics and metatranscriptomics analyses suggest that nitrite oxidation is the main pathway of energy production in Nitrospinae. Microautoradiography, linked with catalyzed reporter deposition fluorescence in situ hybridization, indicated that Nitrospinae fix 15 to 45% of inorganic carbon in the mesopelagic western North Atlantic. Nitrite oxidation may have a greater impact on the carbon cycle than previously assumed. PMID- 29170236 TI - Three-dimensional mechanical metamaterials with a twist. AB - Rationally designed artificial materials enable mechanical properties that are inaccessible with ordinary materials. Pushing on an ordinary linearly elastic bar can cause it to be deformed in many ways. However, a twist, the counterpart of optical activity in the static case, is strictly zero. The unavailability of this degree of freedom hinders applications in terms of mode conversion and the realization of advanced mechanical designs using coordinate transformations. Here, we aim at realizing microstructured three-dimensional elastic chiral mechanical metamaterials that overcome this limitation. On overall millimeter sized samples, we measure twists per axial strain exceeding 2 degrees /%. Scaling up the number of unit cells for fixed sample dimensions, the twist is robust due to metamaterial stiffening, indicating a characteristic length scale and bringing the aforementioned applications into reach. PMID- 29170235 TI - Control of zeolite framework flexibility and pore topology for separation of ethane and ethylene. AB - The discovery of new materials for separating ethylene from ethane by adsorption, instead of using cryogenic distillation, is a key milestone for molecular separations because of the multiple and widely extended uses of these molecules in industry. This technique has the potential to provide tremendous energy savings when compared with the currently used cryogenic distillation process for ethylene produced through steam cracking. Here we describe the synthesis and structural determination of a flexible pure silica zeolite (ITQ-55). This material can kinetically separate ethylene from ethane with an unprecedented selectivity of ~100, owing to its distinctive pore topology with large heart shaped cages and framework flexibility. Control of such properties extends the boundaries for applicability of zeolites to challenging separations. PMID- 29170237 TI - Creation of a Bose-condensed gas of 87Rb by laser cooling. AB - Protocols for attaining quantum degeneracy in atomic gases almost exclusively rely on evaporative cooling, a time-consuming final step associated with substantial atom loss. We demonstrate direct laser cooling of a gas of rubidium 87 (87Rb) atoms to quantum degeneracy. The method is fast and induces little atom loss. The atoms are trapped in a two-dimensional optical lattice that enables cycles of compression to increase the density, followed by Raman sideband cooling to decrease the temperature. From a starting number of 2000 atoms, 1400 atoms reach quantum degeneracy in 300 milliseconds, as confirmed by a bimodal velocity distribution. The method should be broadly applicable to many bosonic and fermionic species and to systems where evaporative cooling is not possible. PMID- 29170238 TI - Double-trap measurement of the proton magnetic moment at 0.3 parts per billion precision. AB - Precise knowledge of the fundamental properties of the proton is essential for our understanding of atomic structure as well as for precise tests of fundamental symmetries. We report on a direct high-precision measurement of the magnetic moment MUp of the proton in units of the nuclear magneton MUN The result, MUp = 2.79284734462 (+/-0.00000000082) MUN, has a fractional precision of 0.3 parts per billion, improves the previous best measurement by a factor of 11, and is consistent with the currently accepted value. This was achieved with the use of an optimized double-Penning trap technique. Provided a similar measurement of the antiproton magnetic moment can be performed, this result will enable a test of the fundamental symmetry between matter and antimatter in the baryonic sector at the 10-10 level. PMID- 29170239 TI - Current-induced strong diamagnetism in the Mott insulator Ca2RuO4. AB - Mott insulators can host a surprisingly diverse set of quantum phenomena when their frozen electrons are perturbed by various stimuli. Superconductivity, metal insulator transition, and colossal magnetoresistance induced by element substitution, pressure, and magnetic field are prominent examples. Here we report strong diamagnetism in the Mott insulator calcium ruthenate (Ca2RuO4) induced by dc electric current. The application of a current density of merely 1 ampere per centimeter squared induces diamagnetism stronger than that in other nonsuperconducting materials. This change is coincident with changes in the transport properties as the system becomes semimetallic. These findings suggest that dc current may be a means to control the properties of materials in the vicinity of a Mott insulating transition. PMID- 29170240 TI - Learning to be a mentor. PMID- 29170241 TI - How does the canine paw pad attenuate ground impacts? A multi-layer cushion system. AB - Macroscopic mechanical properties of digitigrade paw pads, such as non-linear elastic and variable stiffness, have been investigated in previous studies; however, little is known about the micro-scale structural characteristics of digitigrade paw pads, or the relationship between these characteristics and the exceptional cushioning of the pads. The digitigrade paw pad consists of a multi layered structure, which is mainly comprised of a stratified epithelium layer, a dermis layer and a subcutaneous layer. The stratified epithelium layer and dermal papillae constitute the epidermis layer. Finite element analyses were carried out and showed that the epidermis layer effectively attenuated the ground impact across impact velocities of 0.05-0.4 m/s, and that the von Mises stresses were uniformly distributed in this layer. The dermis layer encompassing the subcutaneous layer can be viewed as a hydrostatic system, which can store, release and dissipate impact energy. All three layers in the paw pad work as a whole to meet the biomechanical requirements of animal locomotion. These findings provide insights into the biomechanical functioning of digitigrade paw pads and could be used to facilitate bio-inspired, ground-contacting component development for robots and machines, as well as contribute to footwear design.

PMID- 29170243 TI - Trajectories of prostate-specific antigen after treatment for prostate cancer. AB - Prostate-specific antigen (PSA) measurements after primary treatment reflect residual tumor burden among men with prostate cancer. Using a mixture model analysis, we identified distinct trajectories of post-treatment PSA measurements and evaluated their associations with prostate cancer mortality. The study sample included 623 US Veterans treated for prostate cancer with curative intent during 1991-1995; 225 men received surgery and 398 men received radiation therapy. Post treatment PSA measurements over a 2-year period for each patient were evaluated in latent class mixture models using the SAS TRAJ procedure, and groups of men with distinct trajectories of PSA were identified. These groups were then assessed for associations with 10-year prostate cancer mortality using proportional hazards analysis. Analyses identified three distinct groups representing patterns of both initial values and changes in PSA over time-after surgery (n=172/31/14) and radiation therapy (n=253/103/22). Men in groups with patterns of higher (compared with the group with lowest) PSA values tended to have worse survival experience: HRs for prostate cancer mortality were 3.45 (P=0.18) and 22.7 (P<0.001) for surgery, and 2.70 (P=0.005) and 18.1 (P<0.001) for radiation therapy. The results indicate that PSA measurements after surgery or radiation therapy with curative intent include groups of men with a diverse spectrum of prognosis for prostate cancer mortality. Although contemporary PSA levels are lower than those observed in the study sample, the corresponding trajectory patterns may become evident shortly after the time of diagnosis and treatment. PMID- 29170244 TI - Diabetes and pre-eclampsia affecting pregnancy: a retrospective cross-sectional study. AB - The interaction between pre-eclampsia and diabetes mellitus (DM) is far from being completely understood. In this study, we compared normal pregnancies with those complicated with pre-eclampsia, gestational DM, and/or pre-existing diabetes to assess the effects of hyperglycemia on placental development. AnInstitutional Review Board (IRB) approved retrospective cross-sectional study with 621 subjects was performed. Statistical analysis was performed using Duncan's post hoc test and analysis of variance. Regardless of diabetes status, patients with pre-eclampsia delivered prematurely. Patients in the group with pre eclampsia and pregestational diabetes delivered much earlier, at 35.0+/-0.4 weeks, when compared with the patients that had pre-eclampsia with gestational diabetes and pre-eclampsia with no diabetes (*P<0.05 for each). Additionally, patients with pre-existing diabetes who developed pre-eclampsia delivered smaller babies than those with pre-existing diabetes without pre-eclampsia (1.00+/-0.03, P<0.05 for each). Pre-existing diabetes with added insult of pre-eclampsia led to fetal growth restriction. This outcome validates the understanding that elevated glucose earlier in pregnancy alters placentogenesis and leads to fetal growth restriction. PMID- 29170246 TI - Parallel Pleistocene amphitropical disjunctions of a parasitic plant and its host. AB - PREMISE OF THE STUDY: Aphyllon is a clade of holoparasites that includes closely related North American and South American species parasitic on Grindelia. Both Aphyllon (Orobanchaceae) and Grindelia (Asteraceae) have amphitropical disjunctions between North America and South America; however, the timing of these patterns and the processes to explain them are unknown. METHODS: Chronograms for the Orobanchaceae and Grindelia and their relatives were constructed using fossil and secondary calibration points, one of which was based on the inferred timing of horizontal gene transfer from a papilionoid legume into the common ancestor of Orobanche and Phelipanche. Elevated rates of molecular evolution in the Orobanchaceae have hindered efforts to determine reliable divergence time estimates in the absence of a fossil record. However, using a horizontal gene transfer event as a secondary calibration overcomes this limitation. These chronograms were used to reconstruct the biogeography of Aphyllon, Grindelia, and relatives using a DEC+J model implemented in RevBayes. KEY RESULTS: Aphyllon had two amphitropical dispersals from North America to South America, while Grindelia had a single dispersal. The dispersal of the Aphyllon lineage that is parasitic on Grindelia (0.40 Ma) took place somewhat after Grindelia began to diversify in South America (0.93 Ma). Using a secondary calibration based on horizontal gene transfer, we infer more recent divergence dates of holoparasitic Orobancheae than previous studies. CONCLUSIONS: Parallel host-parasite amphitropical disjunctions in Grindelia and Aphyllon illustrate one means by which ecological specialization may result in nonindependent patterns of diversity in distantly related lineages. Although Grindelia and Aphyllon both dispersed to South America recently, Grindelia appears to have diversified more extensively following colonization. More broadly, recent Pleistocene glaciations probably have also contributed to patterns of diversity and biogeography of temperate northern hemisphere Orobancheae. We also demonstrate the utility of using horizontal gene transfer events from well-dated clades to calibrate parasite phylogenies in the absence of a fossil record. PMID- 29170247 TI - Origins of North American arid-land Verbenaceae: More than one way to skin a cat. AB - PREMISE OF THE STUDY: Verbenaceae originated and initially diversified in South America in wet forest habitats. They have diversified extensively in arid habitats in both South and North America. This study aims to understand the origin of the North American arid-land members of Verbenaceae. METHODS: A phylogenetic approach is used to examine four genera (Aloysia, Citharexylum, Glandularia, Verbena) in three distinct clades with representatives in North American deserts and disjunct South and North American distributions. Phylogenetic analyses were conducted using maximum likelihood and Bayesian approaches. Analyses included both plastid and nuclear DNA regions and include the first study of Citharexylum and an expanded sampling of tribe Verbeneae (Glandularia and Verbena). Ancestral areas were reconstructed for each group. KEY RESULTS: North American desert species of Aloysia and Glandularia were likely derived from ancestors in arid temperate South America, perhaps by long-distance dispersal. The pattern for Verbena was less clear, with evidence from plastid DNA implicating an Andean dispersal route to the North American clade, whereas nuclear data suggest that the Andean and North American species resulted from independent dispersals from southern South America. A previously unrecognized clade of Andean Verbeneae was discovered, raising the possibility of an Andean origin of Verbena or Verbena and Glandularia. North American desert species of Citharexylum represent multiple, independent origins from mesic habitat ancestors in Mesoamerica. CONCLUSIONS: North American arid-zone Verbenaceae are derived from South and Central American ancestors via multiple avenues, including long distance, amphitropical dispersal, Andean migration corridors, and in situ evolution of desert-adapted species. PMID- 29170248 TI - Memoirs of a frequent flier: Phylogenomics reveals 18 long-distance dispersals between North America and South America in the popcorn flowers (Amsinckiinae). AB - PREMISE OF THE STUDY: American amphitropical disjunction (AAD) is an important but understudied New World biogeographic pattern in which related plants occur in extratropical North America and South America, but are absent in the intervening tropics. Subtribe Amsinckiinae (Boraginaceae) is one of the richest groups of plants displaying the AAD pattern. Here, we infer a time-calibrated molecular phylogeny of the group to evaluate the number, timing, and directionality of AAD events, which yields generalizable insights into the mechanism of AAD. METHODS: We perform a phylogenomic analysis of 139 samples of subtribe Amsinckiinae and infer divergence times using two calibration schemes: with only fossil calibrations and with fossils plus a secondary calibration from a recent family level analysis. Biogeographic analysis was performed in the R package BioGeoBEARS. KEY RESULTS: We document 18 examples of AAD in the Amsinckiinae. Inferred divergence times of these AAD examples were strongly asynchronous, ranging from Miocene (17.1 million years ago [Ma]) to Pleistocene (0.33 Ma), with most (12) occurring <5 Ma. Four events occurred 10-5 Ma, during the second rise of the Andes. All AAD examples had a North America to South America directionality. CONCLUSIONS: Second only to the hyperdiverse Poaceae in number of documented AAD examples, the Amsinckiinae is an ideal system for the study of AAD. Asynchronous divergence times support the hypothesis of long-distance dispersal by birds as the mechanism of AAD in the subtribe and more generally. Further comparative phylogenomic studies may permit biogeographic hypothesis testing and examination of the relationship between AAD and fruit morphology, reproductive biology, and ploidy.

PMID- 29170251 TI - Clustered F8 missense mutations cause hemophilia A by combined alteration of splicing and protein biosynthesis and activity. AB - Dissection of pleiotropic effects of missense mutations, rarely investigated in inherited diseases, is fundamental to understanding genotype-phenotype relationships. Missense mutations might impair mRNA processing in addition to protein properties. As a model for hemophilia A, we investigated the highly prevalent F8 c.6046c>t/p.R2016W (exon 19) mutation. In expression studies exploiting lentiviral vectors, we demonstrated that the amino acid change impairs both Factor VIII (FVIII) secretion (antigen 11.0+/-0.4% of wild-type) and activity (6.0+/-2.9%). Investigations in patients' ectopic F8 mRNA and with minigenes showed that the corresponding nucleotide change also decreases correct splicing to 70+/-5%, which is predicted to lower further FVIII activity (4.2+/ 2%), consistently with patients' levels (<1-5%). Masking the mutated exon 19 region by antisense U7snRNA supported the presence of a splicing regulatory element, potentially affected by several missense mutations causing hemophilia A. Among these, the c.6037g>a (p.G2013R) reduced exon inclusion to 41+/-3% and the c.6053a>g (p.E2018G) to 28+/-2%, similarly to a variant affecting the 5' splice site (c.6113a>g, p.N2038S, 26+/-2%), which displayed normal protein features upon recombinant expression. The p.G2013R reduced both antigen (7.0+/-0.9%) and activity (8.4+/-0.8%), while the p.E2018G produced a dysfunctional molecule (antigen: 69.0+/-18.1%; activity: 19.4+/-2.3%). In conclusion, differentially altered mRNA and protein patterns produce a gradient of residual activity, and clarify genotype-phenotype relationships. Data detail pathogenic mechanisms that, only in combination, account for moderate/severe disease forms, which in turn determine the mutation profile. Taken together we provide a clear example of interplay between mRNA and protein mechanisms of disease that operate in shaping many other inherited disorders. PMID- 29170252 TI - Nationwide survey on the use of eltrombopag in patients with severe aplastic anemia: a report on behalf of the French Reference Center for Aplastic Anemia. AB - Few therapeutic options are available for patients with aplastic anemia who are ineligible for transplantation or refractory to immunosuppressive therapy. Eltrombopag was recently shown to produce trilineage responses in refractory patients. However, the effects of real-life use of this drug remain unknown. This retrospective study (2012-2016) was conducted by the French Reference Center for Aplastic Anemia on patients with relapsed/refractory aplastic anemia, and patients ineligible for antithymocyte globulin or transplantation, who received eltrombopag for at least 2 months. Forty-six patients with aplastic anemia were given eltrombopag without prior antithymocyte globulin treatment (n=11) or after antithymocyte globulin administration (n=35) in a relapsed/refractory setting. Eltrombopag (median daily dose 150 mg) was introduced 17 months (range, 8-50) after the diagnosis of aplastic anemia. At last followup, 49% were still receiving treatment, 9% had stopped due to a robust response, 2% due to toxicity and 40% due to eltrombopag failure. Before eltrombopag treatment, all patients received regular transfusions. The overall rates of red blood cell and platelet transfusion independence were 7%, 33%, 46% and 46% at 1, 3, 6 months and last follow-up. Responses were slower to develop in antithymocyte treatment-naive patients. In patients achieving transfusion independence, hemoglobin concentration and platelet counts improved by 3 g/dL (interquartile range, 1.4 4.5) and 42*109/L (interquartile range, 11-100), respectively. Response in at least one lineage (according to National Institutes of Health criteria) was observed in 64% of antithymocyte treatment-naive and 74% of relapsed/refractory patients, while trilineage improvement was observed in 27% and 34%, respectively. We found high rates of hematologic improvement and transfusion independence in refractory aplastic anemia patients but also in patients ineligible for antithymocyte globulin receiving first-line treatment. In conclusion, elderly patients unfit for antithymocyte globulin therapy may benefit from eltrombopag.

PMID- 29170254 TI - WT1 loss attenuates the TP53-induced DNA damage response in T-cell acute lymphoblastic leukemia. AB - Loss-of-function mutations and deletions in Wilms tumor 1 (WT1) gene are present in approximately 10% of T-cell acute lymphoblastic leukemia. Clinically, WT1 mutations are enriched in relapsed series and are associated to inferior relapse free survival in thymic T-cell acute lymphoblastic leukemia cases. Here we demonstrate that WT1 plays a critical role in the response to DNA damage in T cell leukemia. WT1 loss conferred resistance to DNA damaging agents and attenuated the transcriptional activation of important apoptotic regulators downstream of TP53 in TP53-competent MOLT4 T-leukemia cells but not in TP53 mutant T-cell acute lymphoblastic leukemia cell lines. Notably, WT1 loss positively affected the expression of the X-linked inhibitor of apoptosis protein, XIAP, and genetic or chemical inhibition with embelin (a XIAP inhibitor) significantly restored sensitivity to gamma-radiation in both T-cell acute lymphoblastic leukemia cell lines and patient-derived xenografts. These results reveal an important role for the WT1 tumor suppressor gene in the response to DNA damage, and support the view that anti-XIAP targeted therapies could have a role in the treatment of WT1-mutant T-cell leukemia. PMID- 29170255 TI - Outcomes among North American patients with diffuse large B-cell lymphoma are independent of tumor Epstein-Barr virus positivity or immunosuppression. AB - The prevalence, presenting clinical and pathological characteristics, and outcomes for patients with diffuse large B-cell lymphoma that is Epstein-Barr virus positive remain uncertain as does the impact of congenital or iatrogenic immunosuppression. Patients with newly diagnosed diffuse large B-cell lymphoma with available tissue arrays were identified from the University of Iowa/Mayo Clinic Molecular Epidemiology Resource. Patients infected with human immunodeficiency virus or who had undergone a prior organ transplant were excluded. Epstein-Barr virus-associated ribonucleic acid testing was performed on all tissue arrays. A history of significant congenital or iatrogenic immunosuppression was determined for all patients. At enrollment, 16 of the 362 (4.4%) biopsies were positive for Epstein-Barr virus. Thirty-nine (10.8%) patients had a significant history of immunosuppression. Patients with Epstein Barr-positive diffuse large B-cell lymphoma had no unique clinical characteristics but on pathology exhibited a higher frequency of CD30 positivity (25.0% versus 8.1%, respectively; P<0.01), and non-germinal-center subtype (62.5% versus 34.1%, respectively; P<0.01). No baseline clinical characteristics were associated with a history of immunosuppression. With a median follow up of 59 months, and after adjustment for International Prognostic Index, there was no association of Epstein-Barr virus positivity or immunosuppression with event-free survival at 24 months (odds ratio=0.49; 95% confidence interval: 0.13-1.84 and odds ratio=0.81; 95% confidence interval: 0.37-1.77) or overall survival (hazard ratio=0.86; 95% confidence interval: 0.38-1.97 and hazard ratio=1.00; 95% confidence interval: 0.57-1.74). In contrast to non-Western populations, our North American population had a low prevalence of Epstein-Barr virus-positive diffuse large B-cell lymphoma that did not convey an adverse prognosis. A history of immunosuppression, while known to be a risk factor for the development of diffuse large B-cell lymphoma, did not affect subsequent prognosis. PMID- 29170257 TI - Cognitive skills of common shrews (Sorex araneus) vary with seasonal changes in skull size and brain mass. AB - In a rare phenomenon, shrews and a few other species cope with seasonal environments by reducing and regrowing brain size, potentially at the cost of changes in cognitive abilities. Here, we confirm an extensive seasonal shrinkage (21.4%) and regrowth (17.0%) of brain mass in winter and spring, respectively, in the common shrew (Sorex araneus L.) in Southern Germany. In a spatial learning task experiment, individuals with reduced winter brain size covered larger distances to find food, compared with the relatively large-brained summer juveniles and regrown spring adults. By reducing their brain mass, these shrews may reduce their energetic demands, but at the cost of cognitive performance, implying a complex trade-off for coping with seasonally fluctuating resources. These results are relevant for our understanding of evolution and the dynamics of mammalian nervous systems in response to environmental changes. PMID- 29170256 TI - Effects of a physical and energetic challenge on male California mice (Peromyscus californicus): modulation by reproductive condition. AB - Reproduction strongly influences metabolism, morphology and behavior in female mammals. In species in which males provide parental care, reproduction might have similar effects on fathers. We examined effects of an environmental challenge on metabolically important physiological, morphological and behavioral measures, and determined whether these effects differed between reproductive and non reproductive males in the biparental California mouse (Peromyscus californicus). Males were paired with an ovary-intact female, an ovariectomized female treated with estrogen and progesterone to induce estrus, or an untreated ovariectomized female. Within each group, half of the animals were housed under standard laboratory conditions and half in cages requiring them to climb wire towers to obtain food and water; these latter animals were also fasted for 24 h every third day. We predicted that few differences would be observed between fathers and non reproductive males under standard conditions, but that fathers would be in poorer condition than non-reproductive males under challenging conditions. Body and fat mass showed a housing condition*reproductive group interaction: the challenge condition increased body and fat mass in both groups of non-reproductive males, but breeding males were unaffected. Males housed under the physical and energetic challenge had higher blood lipid content, lower maximal aerobic capacity and related traits (hematocrit and relative triceps surae mass), increased pain sensitivity and increased number of fecal boli excreted during tail-suspension tests (a measure of anxiety), compared with controls. Thus, our physical and energetic challenge paradigm altered metabolism, morphology and behavior, but these effects were largely unaffected by reproductive condition. PMID- 29170258 TI - Mechanisms for the functional differentiation of the propulsive and braking roles of the forelimbs and hindlimbs during quadrupedal walking in primates and felines. AB - During quadrupedal walking in most animals, the forelimbs play a net braking role, whereas the hindlimbs are net propulsive. However, the mechanism by which this differentiation occurs remains unclear. Here, we test two models to explain this pattern using primates and felines: (1) the horizontal strut effect (in which limbs are modeled as independent struts), and (2) the linked strut model (in which limbs are modeled as linked struts with a center of mass in between). Video recordings were used to determine point of contact, timing of mid-stance, and limb protraction/retraction duration. Single-limb forces were used to calculate contact time, impulses and the proportion of the stride at which the braking-to-propulsive transition (BP) occurred for each limb. We found no association between the occurrence of the BP and mid-stance, little influence of protraction and retraction duration on the braking-propulsive function of a limb, and a causative relationship between vertical force distribution between limbs and the patterns of horizontal forces. These findings reject the horizontal strut effect, and provide some support for the linked strut model, although predictions were not perfectly matched. We suggest that the position of the center of mass relative to limb contact points is a very important, but not the only, factor driving functional differentiation of the braking and propulsive roles of the limbs in quadrupeds. It was also found that primates have greater differences in horizontal impulse between their limbs compared with felines, a pattern that may reflect a fundamental arboreal adaptation in primates. PMID- 29170259 TI - Sound production mechanism in triggerfish (Balistidae): a synapomorphy. AB - The ability to produce sounds for acoustic communication is known in different Balistidae species but the eventual synapomorphic aspect of the mechanism remains to be shown. In Rhinecanthus aculeatus, sounds result from alternate sweeping movements of the right and left pectoral fins, which push a system of three scutes against the swim bladder wall. In this study, we made a comparison between the sounds produced by this species and two additional ones (Balistapus undulatus and Rhinecanthus rectangulus) using hand-held specimens to provide a description of the sound mechanism. The results highlighted that the sound production mechanism is similar in the three species. According to recent phylogenetic data and shared morphological features, this mechanism could be common to the majority of Balistidae family members and all species could be capable of sound production using pectoral fins. PMID- 29170260 TI - Multimodal sensorimotor system in unicellular zoospores of a fungus. AB - Complex sensory systems often underlie critical behaviors, including avoiding predators and locating prey, mates and shelter. Multisensory systems that control motor behavior even appear in unicellular eukaryotes, such as Chlamydomonas, which are important laboratory models for sensory biology. However, we know of no unicellular opisthokonts that control motor behavior using a multimodal sensory system. Therefore, existing single-celled models for multimodal sensorimotor integration are very distantly related to animals. Here, we describe a multisensory system that controls the motor function of unicellular fungal zoospores. We found that zoospores of Allomyces arbusculus exhibit both phototaxis and chemotaxis. Furthermore, we report that closely related Allomyces species respond to either the chemical or the light stimuli presented in this study, not both, and likely do not share this multisensory system. This diversity of sensory systems within Allomyces provides a rare example of a comparative framework that can be used to examine the evolution of sensory systems following the gain/loss of available sensory modalities. The tractability of Allomyces and related fungi as laboratory organisms will facilitate detailed mechanistic investigations into the genetic underpinnings of novel photosensory systems, and how multisensory systems may have functioned in early opisthokonts before multicellularity allowed for the evolution of specialized cell types.

AB - BACKGROUND: Subsequent injury (SI) is a major contributor to disability and costs for individuals and society. AIM: To identify modifiable risk factors predictive of SI and SI health and disability outcomes and costs. OBJECTIVES: To (1) describe the nature of SIs reported to New Zealand's no-fault injury insurer (the Accident Compensation Corporation (ACC)); (2) identify characteristics of people underaccessing ACC for SI; (3) determine factors predicting or protecting against SI; and (4) investigate outcomes for individuals, and costs to society, in relation to SI. DESIGN: Prospective cohort study. METHODS: Previously collected data will be linked including data from interviews undertaken as part of the earlier Prospective Outcomes of Injury Study (POIS), ACC electronic data and national hospitalisation data about SI. POIS participants (N=2856, including 566 Maori) were recruited via ACC's injury register following an injury serious enough to warrant compensation entitlements. We will examine SI over the following 24 months for these participants using descriptive and inferential statistics including multivariable generalised linear models and Cox's proportional hazards regression. DISCUSSION: Subsequent Injury Study (SInS) will deliver information about the risks, protective factors and outcomes related to SI for New Zealanders. As a result of sourcing injury data from New Zealand's 'all injury' insurer ACC, SInS includes people who have been hospitalised and not hospitalised for injury. Consequently, SInS will provide insights that are novel internationally as other studies are usually confined to examining trauma registries, specific injuries or injured workers who are covered by a workplace insurer rather than a 'real-world' injury population.

PMID- 29170266 TI - Posttreatment Infarct Volumes when Compared with 24-Hour and 90-Day Clinical Outcomes: Insights from the REVASCAT Randomized Controlled Trial. AB - BACKGROUND AND PURPOSE: Endovascular therapy has become the standard of care for patients with disabling anterior circulation ischemic stroke due to proximal intracranial thrombi. Our aim was to determine whether the beneficial effect of endovascular treatment on functional outcome could be explained by a reduction in posttreatment infarct volume in the Endovascular Revascularization With Solitaire Device Versus Best Medical Therapy in Anterior Circulation Stroke Within 8 Hours (REVASCAT) trial. MATERIALS AND METHODS: The REVASCAT trial was a multicenter randomized open-label trial with blinded outcome evaluation. Among 206 enrolled subjects (endovascular treatment, n = 103; control, n = 103), posttreatment infarct volume was measured in 204 subjects. Posttreatment infarct volumes were compared with treatment assignment and recanalization status. Appropriate statistical models were used to assess the relationship among baseline clinical and imaging variables, posttreatment infarct volume, the 24-hour NIHSS score, and functional status with the 90-day modified Rankin Scale score. RESULTS: The median posttreatment infarct volume in all subjects was 23.7 mL (interquartile range = 68.9 mL) and 16.3 mL (interquartile range = 50.2 mL) in the endovascular treatment arm and 38.6 mL (interquartile range = 74.9 mL) in the control arm (P = .02 for endovascular treatment versus control subjects). Baseline NIHSS (P < .01), site of occlusion (P < .03), baseline NCCT ASPECTS (P < .01), and recanalization status (P = .02) were independently associated with posttreatment infarct volume. Baseline NIHSS (P < .01), time from symptom onset to randomization (P = .02), treatment type (P = .04), and recanalization status (P < .01) were independently associated with the 24-hour NIHSS scores. The 24-hour NIHSS score strongly mediated the relationship between treatment type and 90-day mRS (P < .01 for indirect effect when adjusted for age), while posttreatment infarct volume did not (P = .26). CONCLUSIONS: Endovascular treatment saves brain and improves 90-day clinical outcomes primarily through a beneficial effect on the 24-hour stroke severity. PMID- 29170267 TI - Perivascular Spaces in Old Age: Assessment, Distribution, and Correlation with White Matter Hyperintensities. AB - BACKGROUND AND PURPOSE: The visual rating scales for perivascular spaces vary considerably. We sought to develop a new scale for visual assessment of perivascular spaces and to further describe their distribution and association with white matter hyperintensities in old age. MATERIALS AND METHODS: This population-based study included 530 individuals who did not have dementia and were not institutionalized (age, >=60 years or older; mean age, 70.7 years; 58.9% women) who were living in central Stockholm, Sweden. A semiquantitative visual rating scale was developed to score the number and size of visible perivascular spaces in 7 brain regions in each hemisphere. A modified Scheltens visual rating scale was used to assess white matter hyperintensities. RESULTS: The global scores for perivascular spaces ranged from 4-32 for number, 3-22 for size, and 7 54 for the combination of number and size. The weighted kappa statistics for the intra- and interrater reliability both were 0.77. The global score for the number of perivascular spaces increased with advancing age (P < .001). The scores for the number of perivascular spaces in the basal ganglia and subinsular regions were significantly correlated with the load of white matter hyperintensities, especially in lobar and deep white matter regions (partial correlation coefficients, >0.223; P < .01). CONCLUSIONS: The new visual rating scale for perivascular spaces shows excellent intra- and interrater reliability. The number of perivascular spaces globally and, especially, in the basal ganglia, is correlated with the load of lobar and deep white matter hyperintensities, supporting the view that perivascular spaces are a marker for cerebral small vessel disease. PMID- 29170268 TI - Leukoaraiosis Attenuates Diagnostic Accuracy of Large-Vessel Occlusion Scales. AB - BACKGROUND AND PURPOSE: Prehospital stroke scales may help identify patients likely to have large-vessel occlusion to facilitate rapid triage to thrombectomy capable stroke centers. Scale misclassification may result in inaccurate decisions and possible harm. Pre-existing leukoaraiosis has been shown to attenuate the association between deficit type and stroke severity. We sought to determine whether leukoaraiosis affects the predictive ability of 5 commonly used large-vessel occlusion scales. MATERIALS AND METHODS: We retrospectively analyzed 274 consecutive patients with stroke with available brain MR imaging and vessel imaging. We used the following large-vessel occlusion scales: the 3-Item Stroke Scale; Field Assessment Stroke Triage for Emergency Destination; Rapid Arterial Occlusion Evaluation; Vision, Aphasia, Neglect score; and Cincinnati Prehospital Stroke Severity Scale. For diagnostic scale accuracy, we assessed sensitivity, specificity, positive predictive value, negative predictive value, and kappa. Multivariable logistic regression was used to determine the predictive ability of the scales after adjustment for leukoaraiosis and potential confounders. RESULTS: In unadjusted analyses, all scales predicted the presence of large-vessel occlusion (n = 46, P < .01 each), though diagnostic accuracy was attenuated among patients with moderate-to-severe leukoaraiosis. After adjustment, the Field Assessment Stroke Triage for Emergency Destination (OR = 3.2; 95% CI, 1.1-9.5; P = .033) and Rapid Arterial Occlusion Evaluation (OR = 3.7; 95% CI, 1.3-10.8; P = .015), but not the 3-Item Stroke Scale (OR = 5.4; 95% CI, 0.86-33.9; P = .073), Vision, Aphasia, Neglect score (OR = 2.5; 95% CI, 0.8-7.2), and Cincinnati Prehospital Stroke Severity Scale (OR = 2.8; 95% CI, 1.0-8.0), predicted large vessel occlusion. CONCLUSIONS: The diagnostic accuracy of the tested large-vessel occlusion scales was attenuated in the presence of moderate-to-severe leukoaraiosis. This information that may aid the design of future studies that require large-vessel occlusion scale screening of patients who are likely to have concomitant leukoaraiosis. PMID- 29170269 TI - Feasibility of Brain Atrophy Measurement in Clinical Routine without Prior Standardization of the MRI Protocol: Results from MS-MRIUS, a Longitudinal Observational, Multicenter Real-World Outcome Study in Patients with Relapsing Remitting MS. AB - BACKGROUND AND PURPOSE: Feasibility of brain atrophy measurement in patients with MS in clinical routine, without prior standardization of the MRI protocol, is unknown. Our aim was to investigate the feasibility of brain atrophy measurement in patients with MS in clinical routine. MATERIALS AND METHODS: Multiple Sclerosis and Clinical Outcome and MR Imaging in the United States (MS-MRIUS) is a multicenter (33 sites), retrospective study that included patients with relapsing-remitting MS who began treatment with fingolimod. Brain MR imaging examinations previously acquired at the baseline and follow-up periods on 1.5T or 3T scanners with no prior standardization were used, to resemble a real-world situation. Brain atrophy outcomes included the percentage brain volume change measured by structural image evaluation with normalization of atrophy on 2D-T1 weighted imaging and 3D-T1WI and the percentage lateral ventricle volume change, measured by VIENA on 2D-T1WI and 3D-T1WI and NeuroSTREAM on T2-fluid-attenuated inversion recovery examinations. RESULTS: A total of 590 patients, followed for 16 months, were included. There were 585 (99.2%) T2-FLAIR, 425 (72%) 2D-T1WI, and 166 (28.2%) 3D-T1WI longitudinal pairs of examinations available. Excluding MR imaging examinations with scanner changes, the analyses were available on 388 (65.8%) patients on T2-FLAIR for the percentage lateral ventricle volume change, 259 and 257 (43.9% and 43.6%, respectively) on 2D-T1WI for the percentage brain volume change and the percentage lateral ventricle volume change, and 110 (18.6%) on 3D-T1WI for the percentage brain volume change and percentage lateral ventricle volume change. The median annualized percentage brain volume change was -0.31% on 2D-T1WI and -0.38% on 3D-T1WI. The median annualized percentage lateral ventricle volume change was 0.95% on 2D-T1WI, 1.47% on 3D-T1WI, and 0.90% on T2 FLAIR. CONCLUSIONS: Brain atrophy was more readily assessed by estimating the percentage lateral ventricle volume change on T2-FLAIR compared with the percentage brain volume change or percentage lateral ventricle volume change using 2D- or 3D-T1WI in this observational retrospective study. Although measurement of the percentage brain volume change on 3D-T1WI remains the criterion standard and should be encouraged in future prospective studies, T2 FLAIR-derived percentage lateral ventricle volume change may be a more feasible surrogate when historical or other practical constraints limit the availability of percentage brain volume change on 3D-T1WI. PMID- 29170270 TI - The Role of Hemodynamics in Intracranial Bifurcation Arteries after Aneurysm Treatment with Flow-Diverter Stents. AB - BACKGROUND AND PURPOSE: Treatment of intracranial bifurcation aneurysms with flow diverter stents can lead to caliber changes of the distal vessels in a subacute phase. This study aims to evaluate whether local anatomy and flow disruption induced by flow-diverter stents are associated with vessel caliber changes in intracranial bifurcations. MATERIALS AND METHODS: Radiologic images and demographic data were acquired for 25 patients with bifurcation aneurysms treated with flow-diverter stents. Whisker plots and Mann-Whitney rank sum tests were used to evaluate if anatomic data and caliber changes could be linked. Symmetry/asymmetry were defined as diameter ratio 1 = symmetric and diameter ratio <1 = asymmetric. Computational fluid dynamics was performed on idealized and patient-specific anatomies to evaluate flow changes induced by flow-diverter stents in the jailed vessel. RESULTS: Statistical analysis identified a marked correspondence between asymmetric bifurcation and caliber change. Symmetry ratios were lower for cases showing narrowing or subacute occlusion (medium daughter vessel diameter ratio = 0.59) compared with cases with posttreatment caliber conservation (medium daughter vessel diameter ratio = 0.95). Computational fluid dynamics analysis in idealized and patient-specific anatomies showed that wall shear stress in the jailed vessel was more affected when flow-diverter stents were deployed in asymmetric bifurcations (diameter ratio <0.65) and less affected when deployed in symmetric anatomies (diameter ratio ~1.00). CONCLUSIONS: Anatomic data analysis showed statistically significant correspondence between caliber changes and bifurcation asymmetry characterized by diameter ratio <0.7 (P < .001). Similarly, computational fluid dynamics results showed the highest impact on hemodynamics when flow-diverter stents are deployed in asymmetric bifurcations (diameter ratio <0.65) with noticeable changes on wall sheer stress fields. Further research and clinical validation are necessary to identify all elements involved in vessel caliber changes after flow-diverter stent procedures. PMID- 29170271 TI - Temporal Lobe Malformations in Achondroplasia: Expanding the Brain Imaging Phenotype Associated with FGFR3-Related Skeletal Dysplasias. AB - Thanatophoric dysplasia, achondroplasia, and hypochondroplasia belong to the fibroblast growth factor receptor 3 (FGFR3) group of genetic skeletal disorders. Temporal lobe abnormalities have been documented in thanatophoric dysplasia and hypochondroplasia, and in 1 case of achondroplasia. We retrospectively identified 13 children with achondroplasia who underwent MR imaging of the brain between 2002 and 2015. All children demonstrated a deep transverse temporal sulcus on MR imaging. Further common neuroimaging findings were incomplete hippocampal rotation (12 children), oversulcation of the mesial temporal lobe (11 children), loss of gray-white matter differentiation of the mesial temporal lobe (5 children), and a triangular shape of the temporal horn (6 children). These appearances are very similar to those described in hypochondroplasia, strengthening the association of temporal lobe malformations in FGFR3-associated skeletal dysplasias. PMID- 29170272 TI - Vertebroplasty and Kyphoplasty for Osteoporotic Vertebral Fractures: What Are the Latest Data? AB - Osteoporotic vertebral compression fractures frequently result in significant morbidity and health care resource use. For patients with severe and disabling pain, vertebral augmentation (vertebroplasty and kyphoplasty) is often considered. Although vertebroplasty was introduced >30 years ago, there are conflicting opinions regarding the role of these procedures in the treatment of osteoporotic vertebral compression fractures. This review article updates clinicians on the published prospective randomized controlled data, including the most recent positive trials that followed initial negative trials in 2009. Analysis of multiple national claim datasets has also provided further insight into the utility of these procedures. Finally, we considered the recent recommendations of national organizations and medical societies that advise on the use of vertebral augmentation procedures for osteoporotic vertebral compression fractures.

PMID- 29170273 TI - Optimization of Quantitative Dynamic Postgadolinium MRI Technique Using Normalized Ratios for the Evaluation of Temporomandibular Joint Synovitis in Patients with Juvenile Idiopathic Arthritis. AB - BACKGROUND AND PURPOSE: MR imaging has been shown to be useful in the diagnosis of juvenile idiopathic arthritis of the temporomandibular joint. Prior MR imaging approaches have relied mainly on the subjective interpretation of synovial enhancement as a marker for synovial inflammation. Although, more recently, several attempts have been made to quantify synovial enhancement, these methods have not taken into account the dynamic enhancement characteristics of the temporomandibular joint and the effect of sampling time. Our aim was to develop a clinically feasible, reproducible, dynamic, contrast-enhanced MR imaging technique for the quantitative assessment of temporomandibular joint synovitis in patients with juvenile idiopathic arthritis and to study the effect of sampling time on the evaluation of synovitis. MATERIALS AND METHODS: This was a retrospective study of all patients who had dynamic, contrast-enhanced coronal T1 3T MR imaging through the temporomandibular joint at our institution between January 1, 2015, and July 8, 2016. Patients in this cohort included those with a history of juvenile idiopathic arthritis and control patients who underwent MR imaging for other routine, clinical purposes. Synovial enhancement was calculated for each temporomandibular joint using 3 different types of equations termed normalization ratios. The enhancement profiles generated by each equation were studied to determine which provided the best discrimination between affected and unaffected joints, was the least susceptible to sampling errors, and was the most clinically feasible. RESULTS: A ratio of synovial enhancement (defined as the difference between the postgadolinium and the pregadolinium T1 signal of the synovium) to the postgadolinium signal of the longus capitis provided the best discrimination between affected and unaffected joints, the least susceptibility to sampling error, and was thought to be the most clinically feasible method of quantification of synovial inflammation. Additional synovial enhancement ratios studied did not provide the same level rates of discrimination between the affected and unaffected joints and were thought to be too temporally variable to provide reliable clinical use. CONCLUSIONS: We provide a robust, reproducible, dynamic gadolinium-enhanced MR imaging technique for the quantitative assessment of temporomandibular joint synovitis in patients with juvenile idiopathic arthritis.

PMID- 29170277 TI - Rapid hybrid speciation in Darwin's finches. AB - Homoploid hybrid speciation in animals has been inferred frequently from patterns of variation, but few examples have withstood critical scrutiny. Here we report a directly documented example, from its origin to reproductive isolation. An immigrant Darwin's finch to Daphne Major in the Galapagos archipelago initiated a new genetic lineage by breeding with a resident finch (Geospiza fortis). Genome sequencing of the immigrant identified it as a G. conirostris male that originated on Espanola >100 kilometers from Daphne Major. From the second generation onward, the lineage bred endogamously and, despite intense inbreeding, was ecologically successful and showed transgressive segregation of bill morphology. This example shows that reproductive isolation, which typically develops over hundreds of generations, can be established in only three. PMID- 29170278 TI - A mitosis-specific and R loop-driven ATR pathway promotes faithful chromosome segregation. AB - The ataxia telangiectasia mutated and Rad3-related (ATR) kinase is crucial for DNA damage and replication stress responses. Here, we describe an unexpected role of ATR in mitosis. Acute inhibition or degradation of ATR in mitosis induces whole-chromosome missegregation. The effect of ATR ablation is not due to altered cyclin-dependent kinase 1 (CDK1) activity, DNA damage responses, or unscheduled DNA synthesis but to loss of an ATR function at centromeres. In mitosis, ATR localizes to centromeres through Aurora A-regulated association with centromere protein F (CENP-F), allowing ATR to engage replication protein A (RPA)-coated centromeric R loops. As ATR is activated at centromeres, it stimulates Aurora B through Chk1, preventing formation of lagging chromosomes. Thus, a mitosis specific and R loop-driven ATR pathway acts at centromeres to promote faithful chromosome segregation, revealing functions of R loops and ATR in suppressing chromosome instability. PMID- 29170279 TI - Multiplex recording of cellular events over time on CRISPR biological tape. AB - Although dynamics underlie many biological processes, our ability to robustly and accurately profile time-varying biological signals and regulatory programs remains limited. Here we describe a framework for storing temporal biological information directly in the genomes of a cell population. We developed a "biological tape recorder" in which biological signals trigger intracellular DNA production that is then recorded by the CRISPR-Cas adaptation system. This approach enables stable recording over multiple days and accurate reconstruction of temporal and lineage information by sequencing CRISPR arrays. We further demonstrate a multiplexing strategy to simultaneously record the temporal availability of three metabolites (copper, trehalose, and fucose) in the environment of a cell population over time. This work enables the temporal measurement of dynamic cellular states and environmental changes and suggests new applications for chronicling biological events on a large scale. PMID- 29170281 TI - Synthesis of ultrasmall, homogeneously alloyed, bimetallic nanoparticles on silica supports. AB - Supported nanoparticles containing more than one metal have a variety of applications in sensing, catalysis, and biomedicine. Common synthesis techniques for this type of material often result in large, unalloyed nanoparticles that lack the interactions between the two metals that give the particles their desired characteristics. We demonstrate a relatively simple, effective, generalizable method to produce highly dispersed, well-alloyed bimetallic nanoparticles. Ten permutations of noble and base metals (platinum, palladium, copper, nickel, and cobalt) were synthesized with average particle sizes from 0.9 to 1.4 nanometers, with tight size distributions. High-resolution imaging and x ray analysis confirmed the homogeneity of alloying in these ultrasmall nanoparticles. PMID- 29170280 TI - Analysis of Fusobacterium persistence and antibiotic response in colorectal cancer. AB - Colorectal cancers comprise a complex mixture of malignant cells, nontransformed cells, and microorganisms. Fusobacterium nucleatum is among the most prevalent bacterial species in colorectal cancer tissues. Here we show that colonization of human colorectal cancers with Fusobacterium and its associated microbiome including Bacteroides, Selenomonas, and Prevotella species-is maintained in distal metastases, demonstrating microbiome stability between paired primary and metastatic tumors. In situ hybridization analysis revealed that Fusobacterium is predominantly associated with cancer cells in the metastatic lesions. Mouse xenografts of human primary colorectal adenocarcinomas were found to retain viable Fusobacterium and its associated microbiome through successive passages. Treatment of mice bearing a colon cancer xenograft with the antibiotic metronidazole reduced Fusobacterium load, cancer cell proliferation, and overall tumor growth. These observations argue for further investigation of antimicrobial interventions as a potential treatment for patients with Fusobacterium-associated colorectal cancer. PMID- 29170282 TI - Histone methyltransferase SUV39H1 participates in host defense by methylating mycobacterial histone-like protein HupB. AB - Host cell defense against an invading pathogen depends upon various multifactorial mechanisms, several of which remain undiscovered. Here, we report a novel defense mechanism against mycobacterial infection that utilizes the histone methyltransferase, SUV39H1. Normally, a part of the host chromatin, SUV39H1, was also found to be associated with the mycobacterial bacilli during infection. Its binding to bacilli was accompanied by trimethylation of the mycobacterial histone-like protein, HupB, which in turn reduced the cell adhesion capability of the bacilli. Importantly, SUV39H1-mediated methylation of HupB reduced the mycobacterial survival inside the host cell. This was also true in mice infection experiments. In addition, the ability of mycobacteria to form biofilms, a survival strategy of the bacteria dependent upon cell-cell adhesion, was dramatically reduced in the presence of SUV39H1. Thus, this novel defense mechanism against mycobacteria represents a surrogate function of the epigenetic modulator, SUV39H1, and operates by interfering with their cell-cell adhesion ability. PMID- 29170283 TI - Local anaesthetics combined with vasoconstrictors in patients with cardiovascular disease undergoing dental procedures: systematic review and meta-analysis protocol. AB - INTRODUCTION: The use of vasoconstrictors combined with local anaesthetics (LAs) in dentistry for patients with cardiovascular disease (CVD) is still controversial in the scientific literature. It raises concerns regarding the possibility of transient episodes, triggering negative cardiovascular outcomes. METHOD/DESIGN: Trials eligible for our systematic review will enrol patients with CVD who have undergone dental treatments carried out with the use of LAs by comparing two arms: LAs with vasoconstrictors and LAs without vasoconstrictors. The research will be conducted in the electronic databases, namely Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Healthstar (via Ovid), Cumulative Index to Nursing and Allied Health Literature and Web of Science, from their inception to December 2017, without any restrictions in terms of language and status of publication. A team of reviewers will independently assess titles, abstracts and complete text to determine eligibility. For eligible studies, the same reviewers will perform data extraction and evaluate the risk of bias in the selected articles. The selected outcomes comprise death, mortality by a specific cause, stroke, acute myocardial infarction, hospitalisation, pain, bleeding, arrhythmias, ischaemic episodes, anxiety, adverse effects, changes in blood pressure, changes in heart rate, anxiety and results obtained via oximetry. Whenever possible, we will conduct a meta-analysis to establish the effects of LAs with and without vasoconstrictors in the patients with CVD, and the overall quality of evidence for each outcome will be determined using the Grading of Recommendations Assessment, Development and Evaluation classification system. ETHICS AND DISSEMINATION: Ethics committee approval was not necessary because this is a protocol of systematic review. This systematic review will be submitted for presentation at conferences and for publication in a peer-reviewed journal. Our review will assess the risks of cardiovascular events when using LAs with and without vasoconstrictors in patients with CVD, focusing on important clinical outcomes.

PMID- 29170284 TI - Impact of multimorbidity on healthcare professional task shifting potential in patients with type 2 diabetes in primary care: a French cross-sectional study. AB - OBJECTIVES: To estimate the transferability of processes of care from general practitioners (GPs) to allied healthcare professionals and the determinants of such transferability. DESIGN: French national cross-sectional multicentre study SETTING: 128 family practices providing supervised training for residents in general practice. PARTICIPANTS: All patients consulting with their GP over a total number of 20 days (ie, 1 day a week from December 2011 to April 2012). Encounters where type 2 diabetes was one of the managed health problems were selected for analysis. PRIMARY AND SECONDARY OUTCOME MEASURES: Processes that were associated with specific health problems were collected by 54 residents. Potential process transferability was the main outcome assessed, as well as the professionals involved in the collaboration and the eventual conditions associated with transfer. RESULTS: From 8572 processes of care that concerned 1088 encounters of patients with diabetes, 21.9% (95% CI 21.1% to 22.8%) were considered eligible for transfer from GPs to allied healthcare professionals (78.1% to nurses, 36.7% to pharmacists). Processes were transferable with condition(s) for 70.6% (ie, a protocol, shared record or supervision). The most transferable processes concerned health maintenance (32.1%) and cardiovascular risk factors (hypertension (28.7%), dyslipidaemia (25.3%) and diabetes (24.3%)). Multivariate analysis showed that educational processes or a long-term condition status were associated with increased transferability (OR 3.26 and 1.47, respectively), whereas patients with higher intellectual occupations or those with two or more associated health problems were associated with lower transferability (OR 0.33 and 0.81, respectively). CONCLUSIONS: A significant part of GP activity relating to patients with multimorbidity including type 2 diabetes could be transferred to allied healthcare professionals, mainly on prevention and global education to cardiovascular risk factors. The organisational and finance conditions of team work as views of patients and healthcare professionals must be explored before implementation in primary care. PMID- 29170285 TI - Categorising cancers to enable tailored care planning through a secondary analysis of cancer registration data in the UK. AB - OBJECTIVES: The aim of this study is to categorise cancers into broad groups based on clusters of common treatment aims, experiences and outcomes to provide a numerical framework for understanding the services required to meet the needs of people with different cancers. This framework will enable a high-level overview of care and support requirements for the whole cancer population. SETTING AND PARTICIPANTS: People in the UK with 1 of 20 common cancers; an estimated 309 000 diagnoses in 2014, 1 679 000 people diagnosed in a 20-year period and still living in 2010 and 135 000 cancer deaths in 2014. PRIMARY AND SECONDARY OUTCOME MEASURES: Survival and stage at diagnosis data were reviewed alongside clinically led assumptions to identify commonalities and cluster cancer types into three groups. The three cancer groups were then described using incidence, prevalence and mortality data collected and reported by UK cancer registries. This was then reviewed, validated and refined following consultation. RESULTS: Group 1 includes cancers with the highest survival; 5-year survival is over 80%. Group 3 cancers have shorter term survival. Five-year survival is not >20% for any cancer in this group and many do not survive over a year. Group 2 includes cancers where people typically live more than a year but are less likely to live >5 years. We estimate that the majority (64%) of people living with cancer (20 year prevalence) have a cancer type in group 1 'longer term survival', but significant minorities of people have cancers in group 2 'intermediate survival' (19%) and group 3 'shorter term survival' (10%). CONCLUSIONS: Every person with cancer has unique needs shaped by a multitude of factors including comorbidities, treatment regimens, patient preferences, needs, attitudes and behaviours. However, to deliver personalised care, there needs to be a high-level view of potential care requirements to support service planning. PMID- 29170286 TI - The effect of nut consumption on markers of inflammation and endothelial function: a systematic review and meta-analysis of randomised controlled trials. AB - OBJECTIVES: To examine the effect of nut consumption on inflammatory biomarkers and endothelial function. DESIGN: A systematic review and meta-analysis. DATA SOURCES: MEDLINE, PubMed, Cumulative Index to Nursing and Allied Health Literature and Cochrane Central Register of Controlled Trials (all years to 13 January 2017). ELIGIBILITY CRITERIA: Randomised controlled trials (with a duration of 3 weeks or more) or prospective cohort designs conducted in adults; studies assessing the effect of consumption of tree nuts or peanuts on C-reactive protein (CRP), adiponectin, tumour necrosis factor alpha, interleukin-6, intercellular adhesion molecule 1, vascular cell adhesion protein 1 and flow mediated dilation (FMD). DATA EXTRACTION AND ANALYSIS: Relevant data were extracted for summary tables and analyses by two independent researchers. Random effects meta-analyses were conducted to explore weighted mean differences (WMD) in change or final mean values for each outcome. RESULTS: A total of 32 studies (all randomised controlled trials) were included in the review. The effect of nut consumption on FMD was explored in nine strata from eight studies (involving 652 participants), with consumption of nuts resulting in significant improvements in FMD (WMD: 0.79%(95% CI 0.35 to 1.23)). Nut consumption resulted in small, non significant differences in CRP (WMD: -0.01 mg/L (95% CI -0.06 to 0.03)) (26 strata from 25 studies), although sensitivity analyses suggest results for CRP may have been influenced by two individual studies. Small, non-significant differences were also found for other biomarkers of inflammation. CONCLUSIONS: This systematic review and meta-analysis of the effects of nut consumption on inflammation and endothelial function found evidence for favourable effects on FMD, a measure of endothelial function. Non-significant changes in other biomarkers indicate a lack of consistent evidence for effects of nut consumption on inflammation. The findings of this analysis suggest a need for more research in this area, with a particular focus on randomised controlled trials. PROSPERO REGISTRATION NUMBER: CRD42016045424. PMID- 29170287 TI - Maternal and neonatal outcomes of vaginal breech delivery for singleton term pregnancies in a carefully selected Cameroonian population: a cohort study. AB - BACKGROUND AND OBJECTIVES: Vaginal breech delivery (VBD) is known to be associated with more perinatal and maternal complications. Very few studies on the subject have been carried out in poor-resource settings. The aim of this study was to determine maternal and neonatal outcomes in carefully selected cases of VBD for singleton term pregnancies in a tertiary centre in Cameroon. DESIGN: A retrospective cohort study. SETTING: A tertiary hospital in Yaounde, Cameroon. PARTICIPANTS: Cases of VBD of newborns weighing 2500-3500 g were matched in a ratio of 1:4 to consecutive vaginal cephalic deliveries (VCDs) of newborns weighing 2500-3500 g over a 5-year period. Both groups were matched for maternal age and parity. We excluded cases of multiple gestations, footling breech, clinically inadequate maternal pelvis, preterm delivery, post-term pregnancies, fetal demise prior to the onset of labour, placenta praevia and fetal anomaly incompatible with vaginal delivery. OUTCOME MEASURES: Neonatal and maternal adverse outcomes of VBD observed till 6 weeks after delivery analysed using Bonferroni correction. RESULTS: Fifty-three (53) VBDs were matched against 212 VCD. Unlike women who had VCD, those who underwent VBD were more likely to have prolonged labour (OR 8.05; 95% CI 3.00 to 11.47; P<0.001), and their newborns were more likely to suffer from birth asphyxia (OR 10.24; 95% CI 4.92 to 21.31; P<0.001). CONCLUSION: The study infers a strong association between VBD of singleton term pregnancies and maternofetal morbidity when specific protocols are applied. This, however, failed to translate into higher differences in perinatal mortality. This finding does not discount the role of VBD in low-income countries, but we emphasise the need for specific precautions like close monitoring of labour and adequate anticipation for neonatal resuscitation in order to reduce these complications. PMID- 29170288 TI - Midwife or doctor local opinion leader to implement a national guideline in babies on postnatal wards (DesIGN): protocol of a cluster-randomised, blinded, controlled trial. AB - INTRODUCTION: Neonatal hypoglycaemia is a common condition that can cause developmental delay. Treatment of neonatal hypoglycaemia with oral dextrose gel has been shown to reverse hypoglycaemia and reduce admissions to neonatal intensive care for hypoglycaemia. An evidence-based clinical practice guideline was written to guide the use of dextrose gel to treat neonatal hypoglycaemia in New Zealand. However, it is unclear what clinical discipline might most effectively lead the implementation of the guideline recommendations. OBJECTIVE: To determine if midwife or doctor local opinion leaders are more effective in implementing a clinical practice guideline for use of oral dextrose gel to treat hypoglycaemia in babies on postnatal wards. METHODS AND ANALYSIS: A cluster randomised, blinded, controlled trial. New Zealand maternity hospitals that care for babies born at risk of neonatal hypoglycaemia will be randomised to having either a local midwife or doctor lead the guideline implementation at that hospital. The primary outcome will be the change in the proportion of hypoglycaemic babies treated with dextrose gel from before implementation of the guideline to 3 months after implementation. ETHICS AND DISSEMINATION: Approved by Health and Disability Ethics Committee: 15/NTA/31. Findings will be disseminated to peer-reviewed journals, guideline developers and the public.

AB - OBJECTIVE: To assess the use of driving-impairing medicines (DIM) in the general population with special reference to length of use and concomitant use. DESIGN: Population-based registry study. SETTING: The year 2015 granted medicines consumption data recorded in the Castile and Leon (Spain) medicine dispensation registry was consulted. PARTICIPANTS: Medicines and DIM consumers from a Spanish population (Castile and Leon: 2.4 million inhabitants). EXPOSURE: Medicines and DIM consumption. Patterns of use by age and gender based on the length of use (acute: 1-7 days, subacute: 8-29 days and chronic use: >=30 days) were of interest. Estimations regarding the distribution of licensed drivers by age and gender were employed to determine the patterns of use of DIM. RESULTS: DIM were consumed by 34.4% (95% CI 34.3% to 34.5%) of the general population in 2015, more commonly with regularity (chronic use: 22.5% vs acute use: 5.3%) and more frequently by the elderly. On average, 2.3 DIM per person were dispensed, particularly to chronic users (2.8 DIM per person). Age and gender distribution differences were observed between the Castile and Leon medicine dispensation registry data and the drivers' license census data. Of all DIM dispensed, 83.8% were in the Anatomical Therapeutic Chemical code group nervous system medicines (N), which were prescribed to 29.2% of the population. CONCLUSIONS: The use of DIM was frequent in the general population. Chronic use was common, but acute and subacute use should also be considered. This finding highlights the need to make patients, health professionals, health providers, medicine regulatory agencies and policy-makers at large aware of the role DIM play in traffic safety. PMID- 29170290 TI - Cerebrospinal fluid biomarkers for the diagnosis and prognosis of Parkinson's disease: protocol for a systematic review and individual participant data meta analysis. AB - INTRODUCTION: Idiopathic Parkinson's disease (PD) is a progressive neurodegenerative disorder related to alpha-synuclein misfolding and aggregation. For this reason, it belongs to the family of 'synucleinopathies', which also includes some other neurological diseases. Although imaging and ancillary investigations may be helpful in the diagnostic workup, the diagnosis of PD mostly relies on the clinician's expertise. Furthermore, there is a need today for markers that can track the disease progression in PD that might improve the evaluation of novel disease-modifying therapies. The cerebrospinal fluid (CSF) has been widely investigated with the purpose of finding useful diagnostic and prognostic biomarkers for PD. METHODS AND ANALYSIS: This systematic review protocol has been developed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses Protocol 2015 statement and was registered on the PROSPERO international prospective register of systematic reviews. An international collaboration will be established. We will search the Cochrane Library, Web of Science, Medline and Embase from inception, using appropriate search strategies. Individual participant data from all included studies will be merged into a single database. We will include any study assessing the diagnostic and prognostic role of CSF biomarkers in PD. To evaluate the risk of bias and applicability of primary diagnostic accuracy studies, we will use Quality Assessment of Diagnostic Accuracy Studies-2 and Quality in Prognostic Studies. We will use standard meta-analytic procedures. We will first explore the utility of each CSF biomarker in turn. For each biomarker, we will assess its diagnostic and prognostic utility by means of receiver operating characteristic analysis and regression models. We will then move towards a multivariate approach considering different panels of biomarkers. ETHICS AND DISSEMINATION: Our study will not include confidential data, and no intervention will be involved, so ethical approval is not required. The results of the study will be reported in international peer-reviewed journals. PMID- 29170291 TI - Authorship, plagiarism and conflict of interest: views and practices from low/middle-income country health researchers. AB - OBJECTIVES: To document low/middle-income country (LMIC) health researchers' views about authorship, redundant publication, plagiarism and conflicts of interest and how common poor practice was in their institutions. DESIGN: We developed a questionnaire based on scenarios about authorship, redundant publication, plagiarism and conflicts of interest. We asked participants whether the described practices were acceptable and whether these behaviours were common at their institutions. We conducted in-depth interviews with respondents who agreed to be interviewed. PARTICIPANTS: We invited 607 corresponding authors of Cochrane reviews working in LMICs. From the 583 emails delivered, we obtained 199 responses (34%). We carried out in-depth interviews with 15 respondents. RESULTS: Seventy-seven per cent reported that guest authorship occurred at their institution, 60% reported text recycling. For plagiarism, 12% of respondents reported that this occurred 'occasionally', and 24% 'rarely'. Forty per cent indicated that their colleagues had not declared conflicts of interest in the past. Respondents generally recognised poor practice in scenarios but reported that they occurred at their institutions. Themes identified from in-depth interviews were (1) authorship rules are simple in theory, but not consistently applied; (2) academic status and power underpin behaviours; (3) institutions and culture fuel bad practices and (4) researchers are uncertain about what conflict of interests means and how this may influence research. CONCLUSIONS: LMIC researchers report that guest authorship is widely accepted and common. While respondents report that plagiarism and undeclared conflicts of interest are unacceptable in practice, they appear common. Determinants of poor practice relate to academic status and power, fuelled by institutional norms and culture. PMID- 29170292 TI - Core outcome research measures in anal cancer (CORMAC): protocol for systematic review, qualitative interviews and Delphi survey to develop a core outcome set in anal cancer. AB - INTRODUCTION: The incidence of anal squamous cell carcinoma (ASCC) has increased threefold in the last 30 years. Initial treatment is chemoradiotherapy, associated with short-term and long-term side effects. Future therapy innovations aim to reduce morbidity in treatment of early tumours while maintaining treatment efficacy, and to escalate treatment intensity in locally advanced tumours with acceptable quality of life (QoL). However, all phase III randomised controlled trials to-date have utilised different primary outcomes, which hinders evidence synthesis and presents challenges to the selection of optimal outcomes in future trials. No trial comprehensively assessed long-term side effects and QoL, suggesting outcomes reflecting issues important to patients are under represented. This project aims to determine the priority outcomes for all stakeholders and reach agreement on a standardised core set of outcomes to be measured and reported on in all future ASCC trials. METHODS AND ANALYSIS: A systematic review will identify all outcomes reported in trials and observational studies of chemoradiotherapy as primary treatment for ASCC. Outcomes of importance to patients will be identified through patient interviews. The long list of outcomes generated from the systematic review and interviews will be used to create a two-round Delphi process, including key stakeholders (patients and healthcare professionals). The results of the Delphi will be discussed at a face to-face consensus meeting. Discussion will focus on outcomes that did not achieve consensus through the Delphi process and conclude with anonymous voting to ratify the final core outcome set (COS). ETHICS AND DISSEMINATION: The final COS will feed directly into the PersonaLising Anal cancer radioTherapy dOse (PLATO) national anal cancer trials and the Association of coloproctologists of Great Britain and Ireland (ACPGBI) supported national anal cancer database. Utilisation of the COS will increase the relevance of research output to all stakeholders and increase the capacity for data synthesis between trials. This study has ethical approval and is registered with the Core Outcome Measures in Effectiveness Trials (COMET) initiative. TRIAL REGISTRATION NUMBER: PROSPERO registration ID: CRD42016036540. PMID- 29170293 TI - Identifying clinical features in primary care electronic health record studies: methods for codelist development. AB - OBJECTIVE: Analysis of routinely collected electronic health record (EHR) data from primary care is reliant on the creation of codelists to define clinical features of interest. To improve scientific rigour, transparency and replicability, we describe and demonstrate a standardised reproducible methodology for clinical codelist development. DESIGN: We describe a three-stage process for developing clinical codelists. First, the clear definition a priori of the clinical feature of interest using reliable clinical resources. Second, development of a list of potential codes using statistical software to comprehensively search all available codes. Third, a modified Delphi process to reach consensus between primary care practitioners on the most relevant codes, including the generation of an 'uncertainty' variable to allow sensitivity analysis. SETTING: These methods are illustrated by developing a codelist for shortness of breath in a primary care EHR sample, including modifiable syntax for commonly used statistical software. PARTICIPANTS: The codelist was used to estimate the frequency of shortness of breath in a cohort of 28 216 patients aged over 18 years who received an incident diagnosis of lung cancer between 1 January 2000 and 30 November 2016 in the Clinical Practice Research Datalink (CPRD). RESULTS: Of 78 candidate codes, 29 were excluded as inappropriate. Complete agreement was reached for 44 (90%) of the remaining codes, with partial disagreement over 5 (10%). 13 091 episodes of shortness of breath were identified in the cohort of 28 216 patients. Sensitivity analysis demonstrates that codes with the greatest uncertainty tend to be rarely used in clinical practice. CONCLUSIONS: Although initially time consuming, using a rigorous and reproducible method for codelist generation 'future-proofs' findings and an auditable, modifiable syntax for codelist generation enables sharing and replication of EHR studies. Published codelists should be badged by quality and report the methods of codelist generation including: definitions and justifications associated with each codelist; the syntax or search method; the number of candidate codes identified; and the categorisation of codes after Delphi review.

PMID- 29170295 TI - BET 1: Can the Manchester Acute Coronary Syndromes and Troponin-only Manchester Acute Coronary Syndromes decision aids rule out acute coronary syndromes in the emergency department? AB - A short-cut review was carried out to establish whether the Manchester Acute Coronary Syndromes (MACS) and Troponin-only MACS (T-MACS) decision aids can safely rule out acute coronary syndromes in patients presenting to the ED with suspected cardiac chest pain. Six studies were directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The clinical bottom line is that both rules have high sensitivity for acute coronary syndromes, including the detection of major adverse cardiac events at 30 days. The original MACS algorithm may have marginally greater sensitivity than T MACS but has inferior specificity and requires the use of a biomarker assay (for heart-type fatty acid binding protein) that is not currently widely used in practice. PMID- 29170297 TI - BET 2: Sharing decisions for patients with suspected cardiac chest pain in the emergency department. AB - A short-cut review was carried out to establish whether shared decision making used alongside a decision aid can lead to greater patient satisfaction, lower healthcare resource use and non-inferior clinical outcomes in patients with suspected acute coronary syndromes. Four studies were directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The clinical bottom line is that the use of shared decision-making tools in the ED for management of patients with low-risk chest pain appears to be beneficial to the patient and the physician. Use of these shared decision-making tools appears to increase patient knowledge and satisfaction, while decreasing decision conflict and resource use, without causing additional negative outcomes for the patient. PMID- 29170318 TI - 21 Daily dynamic discharge - a whole system solution to ED crowding. AB - INTRODUCTION: ED crowding is associated with increased mortality, poor staff and patient experience, an increased inpatient length of stay and poor compliance with the four-hour emergency access standard.1 Where crowding is caused by exit block, the focus needs to be on whole system patient management, reducing the temporal mismatch between admissions and discharges since at times of peak demand hospitals may become gridlocked until patients are discharged.In an attempt to tackle exit block, the Scottish Government Unscheduled Care Team have implemented the Daily Dynamic Discharge (DDD) approach, which aims to increase the number of inpatient discharges by 12 pm, thus enabling more timeous flow through the ED. METHODS: A series of meetings were held between the Unscheduled Care Team and the clinical and managerial staff of Dumfries and Galloway Royal Infirmary over a two week period to train staff on implementing the elements of the Daily Dynamic Discharge approach. These included holding a daily whiteboard meeting with input from the multidisciplinary team, early determination of an Estimated Date of Discharge (EDD) for each patient, and conducting 'golden hour' ward rounds whereby the highest acuity patients were seen first followed by those who were expected to be discharged that day, thus increasing the number of discharges by 12 pm. RESULTS: Over a twelve-week period the average number of weekly discharges increased from 26.5 to 30.2, i.e., an average increase of 3.7 discharges per week. Average length of stay dropped from 6.8 days to 6.2 days, a saving of 0.6 days.The median discharge time was 32 min earlier once DDD had been implemented. Previously, a third (33%) of patients were discharged before 4 pm; after implementation, this rose to 44%. DISCUSSION: Emergency Department activity, and particularly crowding, is the barometer for the rest of the hospital, and the only way to guarantee that patients who require admission, get into the right bed, and in a timely way, is to ensure that the downstream wards discharge sufficient numbers early in the day to accommodate admissions from the ED.The DDD approach has been shown to be effective in increasing the number of discharges by 12 pm, smoothing the admission/discharge profile, and is now being adopted in other hospitals throughout Scotland.

AB - Cardiovascular magnetic resonance (CMR) assesses cardiac function, ischaemia, viability and tissue characterisation, all within a single scan. Many studies regarding the role of CMR in stable coronary artery disease (CAD) have been published over the last decade providing important technical advances, large scale clinical validation and prognostic data. As a result, CMR has emerged as a highly accurate technique for diagnosis and risk stratification in stable CAD and has been incorporated into national and international guidelines. Furthermore, clinical pathways utilising CMR have been shown to be the most cost-effective in several healthcare systems. In this review, we summarise the key roles and guideline recommendations for CMR in stable CAD supported by contemporary clinical evidence. PMID- 29170358 TI - Cardiopulmonary fitness in children with congenital heart diseases versus healthy children. AB - OBJECTIVE: We aimed to compare the cardiopulmonary fitness of children with congenital heart diseases (CHD) with that of age-adjusted and gender-adjusted controls. We also intended to identify clinical characteristics associated with maximum oxygen uptake (VO2max) in this population. METHODS AND RESULTS: We included in a cross-sectional multicentre study a total of 798 children (496 CHD and 302 controls) who underwent a complete cardiopulmonary exercise test (CPET). The association of clinical characteristics with VO2max was studied using a multivariate analysis. Mean VO2max in the CHD group and control represented 93%+/ 20% and 107%+/-17% of predicted values, respectively. VO2max was significantly lower in the CHD group, overall (37.8+/-0.3vs 42.6+/-0.4 mL/kg/min, P<0.0001) and for each group (P<0.05). The mean VO2max decline per year was significantly higher in CHD than in the controls overall (-0.84+/-0.10 vs -0.19+/-0.14 mL/kg/min/year, P<0.01), for boys (-0.72+/-0.14vs 0.11+/-0.19 mL/kg/min/year, P<0.01) and for girls (-1.00+/-0.13 vs -0.55+/-0.21 mL/kg/min/year, P=0.05). VO2max was associated with body mass index, ventilatory anaerobic threshold, female gender, restrictive ventilatory disorder, right ventricle systolic hypertension, tricuspid regurgitation, the number of cardiac catheter or surgery procedures, and the presence of a genetic anomaly. CONCLUSIONS: Although the magnitude of the difference was not large, VO2max among children with CHD was significantly lower than in normal children. We suggest performing CPET in routine follow-up of these patients. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT01202916;Post-results. PMID- 29170359 TI - Non-antibiotic options for recurrent urinary tract infections in women. PMID- 29170360 TI - Sex-specific cardiovascular susceptibility to ischaemic myocardial injury following exposure to prenatal hypoxia. AB - Cardiovascular diseases (CVDs) are the leading cause of mortality and hypertension contributes substantially to the incidence of stroke, coronary artery disease, heart failure, atrial fibrillation and peripheral vascular disease. The origin of hypertension is clearly multifactorial, and a complex and multifaceted approach is necessary to decrease its incidence. The most recognizable factors involved in reducing the incidence of hypertension are prevention, early diagnosis and treatment; however, the importance of the foetal environment and early postnatal development has recently been considered. In clinical practice, these factors are still frequently overlooked, probably because of a lack of knowledge about the underlying mechanisms and effective treatment or prevention. Pathophysiological mechanisms underlying the prenatal programming of CVDs were investigated in the study by Shah et al. published recently in Clinical Science (2017) 131(17), 2303-2317. The study explored cardiac susceptibility of adult male and female rat offspring to ischaemic myocardial injury due to prenatal exposure to hypoxia. The results demonstrated significant changes in global cardiac function and left ventricular dilatation following myocardial infarction in rat offspring prenatally exposed to hypoxia. The effects were gender specific and occurred only in males, whereas females were protected. These findings are important from several perspectives. First, they point to the fact that an inadequate foetal environment can increase susceptibility to death from myocardial infarction. Second, during their reproductive life, females are better protected from cardiovascular insult than males, but it is not known if they lose this advantage after menopause, and can be equally at risk as males. PMID- 29170361 TI - Polycystic ovary syndrome: a common reproductive syndrome with long-term metabolic consequences. AB - Polycystic ovary syndrome is the most common endocrine disorder among women of reproductive age. Although traditionally viewed as a reproductive disorder, there is increasing appreciation that it is associated with significantly increased risk of cardiometabolic disorders. Women with polycystic ovary syndrome may present to clinicians via a variety of different routes and symptoms. Although the impact on reproduction predominates during the reproductive years, the increased cardiometabolic problems are likely to become more important at later stages of the life course. Women with polycystic ovary syndrome have an approximately 2- to 5-fold increased risk of dysglycaemia or type 2 diabetes, and hence regular screening with oral glucose tolerance test is warranted. Although the diagnostic criteria for polycystic ovary syndrome are still evolving and are undergoing revision, the diagnosis is increasingly focused on the presence of hyperandrogenism, with the significance of polycystic ovarian morphology in the absence of associated hyperandrogenism or anovulation remaining uncertain. The management of women with polycystic ovary syndrome should focus on the specific needs of the individual, and may change according to different stages of the life course. In view of the clinical manifestations of the condition, there is recent debate about whether the current name is misleading, and whether the condition should be renamed as metabolic reproductive syndrome. PMID- 29170362 TI - The effect of body mass index on chest trauma severity and prognosis. AB - AIM: Patients with thoracic trauma constitute one third of all the trauma cases, in west Sicily were recorded 941 thoracic trauma during the period between 2006 and 2009. Sicily is one of the Italian regions with the highest rate of obesity: some studies have demonstrated that obesity is an independent risk factor for mortality in high energy blunt traumas. MATERIAL OF STUDY: This study was conducted with trauma patients older than 20 years old who presented to our Department during the last five years. We only included thoracic injuries and politrauma with a thoracic involvement and a BMI >25. Patients were divided into two groups: HET and LET patients. RESULTS: Thoracic trauma was more common in patients with a BMI >25 than in normo-weight and clinic admission rate, length of hospital stay and ISS score increased in proportion with the increase of BMI. Both HET (high energy trauma) and LET (low energy trauma) revealed that overweight, obese and morbidly obese patients had greater admissions and length of hospital stay. DISCUSSION: The overweight and obese population has increased substantially over the last two decades and 61,5% of the Sicilian population is above normal weight. A large body mass with excess adiposity may contribute to HET injuries in several ways. Obesity has a number of comorbidities that reduce chances of recovery in overweight and obese patients experienced thoracic trauma both HET and LET. CONCLUSION: Obesity increases morbidity independently of injury severity in thoracic trauma patients. As BMI increased, length of hospital stay increased and prognosis deteriorates. KEY WORDS: BMI, Obesity, Thoracic trauma. PMID- 29170363 TI - The Influence of Class II Division 2 Malocclusions on the Harmony of the Human Face Profile. AB - BACKGROUND Persons with class II division 2 malocclusion are characterized by a very specific dento-skeletal and soft-tissue profile (a profile in which a protruding nose and chin, retruding lips, concave and shortened lower third of the face, and gummy smile are dominant), which is the opposite of the currently modern profiles (convex profile of protruding lips and small chin). The aim of this research was to determine the differences in parameters of harmonies of facial profiles between persons with class II division 2 malocclusions and class I, and to establish the significance of those differences. MATERIAL AND METHODS For this study, 50 patients with class II division 2 malocclusions and 50 patients with class I were selected; profile photos were recorded and a photometric analysis was done: a type of profile according to Schwarz, the shape of a nose, the prominence of chin, biometrical field, the position of lips in relation to the tangent Sn-Pg, S-line (Steiner), E-line (Riketts) and a facial angle according to Arnett. RESULTS The significant differences in profiles of persons with class II division 2 compared to class I were: position and prominence of the chin, the position of the lower and upper lip in relation to the S-line, and smaller value of a facial angle in relation to persons with class I. CONCLUSIONS The differences seen in skeletal profiles were not associated with significant differences in the profiled facial contours of the examined groups. The compensatory role of the fullness of soft tissues of the lips is probably the reason why there were not significant deviations in all the examined parameters. PMID- 29170364 TI - Acute Fibrinous and Organizing Pneumonia: A Case Report and Review of the Literature. AB - BACKGROUND Acute fibrinous organizing pneumonia (AFOP) is a rare condition of the lung that is associated with acute lung injury, and has a poor prognosis. AFOP is characterized histologically by intra-alveolar fibrin. AFOP has been described to be associated with lung infections, connective tissue disorders, drugs, toxic environmental exposure, and in lung transplantation. However, most cases of AFOP remain idiopathic, and because the condition can present with a wide variety of clinical manifestations, open lung biopsy or video-assisted thoracoscopic (VAT) lung biopsy is necessary for the diagnosis. Currently, treatments for AFOP remain under investigation. CASE REPORT A 35-year-old woman presented with a cough and dyspnea, and was initially diagnosed to have pneumonia. Due to the progression of her symptoms and increasing respiratory failure she underwent video-assisted thoracoscopic (VAT) biopsy and was diagnosed with AFOP, 19 days following hospital admission. She was treated with mechanical ventilation, intravenous steroids, and cyclophosphamide. She required tracheostomy after 14 days of mechanical ventilation and died two weeks later. CONCLUSIONS AFOP is an uncommon clinical condition, with a poor prognosis, which often has a delay in diagnosis. Some patients benefit from steroids and immunosuppressive therapy. Currently, new treatments for AFOP are under investigation.

AB - BACKGROUND In patients with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) co-infection, HIV can modulate HCV replication and immune response as well as accelerate liver fibrosis. The role of miRNA in HIV/HCV co-infection is not fully elucidated. The aim of this study was to examine the differential expression of miRNAs in the liver. MATERIAL AND METHODS Thirteen patients who had undergone a liver transplant (7 HCV-infected and 6 HIV/HCV-co-infected patients) were examined using a miRNA array containing 1347 human miRNAs. To confirm the microarray results, data for 20 patients (10 HCV-infected and 10 HIV/HCV-co infected) were validated using real-time polymerase chain reaction probing for miR101b, miR149, and miR200c. This miRNA was selected based on microarray results and its biological significance in liver fibrosis. RESULTS Microarray analysis revealed 22 miRNAs that were differentially expressed in the HIV/HCV-co-infected group compared to the HCV-infected group (p<0.05). The expression of miR-101b and miR149 was significantly decreased in the HIV/HCV-co-infected group compared to that in the HCV-infected group (miR101b, 0.103+/-0.09 vs. 0.0157+/-0.0093, p=0.007; miR149, 0.152+/-0.159 vs. 0.0192+/-0.015, p=0.025). CONCLUSIONS HIV/HCV co-infection may promote liver fibrosis by modulating miRNA expression. PMID- 29170367 TI - Simulating quantum light propagation through atomic ensembles using matrix product states. AB - A powerful method to interface quantum light with matter is to propagate the light through an ensemble of atoms. Recently, a number of such interfaces have emerged, most prominently Rydberg ensembles, that enable strong nonlinear interactions between propagating photons. A largely open problem is whether these systems produce exotic many-body states of light and developing new tools to study propagation in the large photon number limit is highly desirable. Here we provide a method based on a "spin model" that maps quasi one-dimensional (1D) light propagation to the dynamics of an open 1D interacting spin system, where all photon correlations are obtained from those of the spins. The spin dynamics in turn are numerically solved using the toolbox of matrix product states. We apply this formalism to investigate vacuum induced transparency, wherein the different photon number components of a pulse propagate with number-dependent group velocity and separate at output.

AB - A strategy for HIV-1 vaccine development is to define envelope (Env) evolution of broadly neutralizing antibodies (bnAbs) in infection and to recreate those events by vaccination. Here, we report host tolerance mechanisms that limit the development of CD4-binding site (CD4bs), HCDR3-binder bnAbs via sequential HIV-1 Env vaccination. Vaccine-induced macaque CD4bs antibodies neutralize 7% of HIV-1 strains, recognize open Env trimers, and accumulate relatively modest somatic mutations. In naive CD4bs, unmutated common ancestor knock-in mice Env+B cell clones develop anergy and partial deletion at the transitional to mature B cell stage, but become Env- upon receptor editing. In comparison with repetitive Env immunizations, sequential Env administration rescue anergic Env+ (non-edited) precursor B cells. Thus, stepwise immunization initiates CD4bs-bnAb responses, but immune tolerance mechanisms restrict their development, suggesting that sequential immunogen-based vaccine regimens will likely need to incorporate strategies to expand bnAb precursor pools. PMID- 29170371 TI - Multicomponent mapping of boron chemotypes furnishes selective enzyme inhibitors. AB - Heteroatom-rich organoboron compounds have attracted attention as modulators of enzyme function. Driven by the unmet need to develop chemoselective access to boron chemotypes, we report herein the synthesis of alpha- and beta aminocyano(MIDA)boronates from borylated carbonyl compounds. Activity-based protein profiling of the resulting beta-aminoboronic acids furnishes selective and cell-active inhibitors of the (ox)lipid-metabolizing enzyme alpha/beta hydrolase domain 3 (ABHD3). The most potent compound displays nanomolar in vitro and in situ IC50 values and fully inhibits ABHD3 activity in human cells with no detectable cross-reactivity against other serine hydrolases. These findings demonstrate that synthetic methods that enhance the heteroatom diversity of boron containing molecules within a limited set of scaffolds accelerate the discovery of chemical probes of human enzymes. PMID- 29170369 TI - Stress-responsive FKBP51 regulates AKT2-AS160 signaling and metabolic function. AB - The co-chaperone FKBP5 is a stress-responsive protein-regulating stress reactivity, and its genetic variants are associated with T2D related traits and other stress-related disorders. Here we show that FKBP51 plays a role in energy and glucose homeostasis. Fkbp5 knockout (51KO) mice are protected from high-fat diet-induced weight gain, show improved glucose tolerance and increased insulin signaling in skeletal muscle. Chronic treatment with a novel FKBP51 antagonist, SAFit2, recapitulates the effects of FKBP51 deletion on both body weight regulation and glucose tolerance. Using shorter SAFit2 treatment, we show that glucose tolerance improvement precedes the reduction in body weight. Mechanistically, we identify a novel association between FKBP51 and AS160, a substrate of AKT2 that is involved in glucose uptake. FKBP51 antagonism increases the phosphorylation of AS160, increases glucose transporter 4 expression at the plasma membrane, and ultimately enhances glucose uptake in skeletal myotubes. We propose FKBP51 as a mediator between stress and T2D development, and potential target for therapeutic approaches. PMID- 29170370 TI - Receptor-binding loops in alphacoronavirus adaptation and evolution. AB - RNA viruses are characterized by a high mutation rate, a buffer against environmental change. Nevertheless, the means by which random mutation improves viral fitness is not well characterized. Here we report the X-ray crystal structure of the receptor-binding domain (RBD) of the human coronavirus, HCoV 229E, in complex with the ectodomain of its receptor, aminopeptidase N (APN). Three extended loops are solely responsible for receptor binding and the evolution of HCoV-229E and its close relatives is accompanied by changing loop receptor interactions. Phylogenetic analysis shows that the natural HCoV-229E receptor-binding loop variation observed defines six RBD classes whose viruses have successively replaced each other in the human population over the past 50 years. These RBD classes differ in their affinity for APN and their ability to bind an HCoV-229E neutralizing antibody. Together, our results provide a model for alphacoronavirus adaptation and evolution based on the use of extended loops for receptor binding. PMID- 29170372 TI - High magnesium mobility in ternary spinel chalcogenides. AB - Magnesium batteries appear a viable alternative to overcome the safety and energy density limitations faced by current lithium-ion technology. The development of a competitive magnesium battery is plagued by the existing notion of poor magnesium mobility in solids. Here we demonstrate by using ab initio calculations, nuclear magnetic resonance, and impedance spectroscopy measurements that substantial magnesium ion mobility can indeed be achieved in close-packed frameworks (~ 0.01 0.1 mS cm-1 at 298 K), specifically in the magnesium scandium selenide spinel. Our theoretical predictions also indicate that high magnesium ion mobility is possible in other chalcogenide spinels, opening the door for the realization of other magnesium solid ionic conductors and the eventual development of an all solid-state magnesium battery. PMID- 29170373 TI - Caldera resurgence driven by magma viscosity contrasts. AB - Calderas are impressive volcanic depressions commonly produced by major eruptions. Equally impressive is the uplift of the caldera floor that may follow, dubbed caldera resurgence, resulting from magma accumulation and accompanied by minor eruptions. Why magma accumulates, driving resurgence instead of feeding large eruptions, is one of the least understood processes in volcanology. Here we use thermal and experimental models to define the conditions promoting resurgence. Thermal modelling suggests that a magma reservoir develops a growing transition zone with relatively low viscosity contrast with respect to any newly injected magma. Experiments show that this viscosity contrast provides a rheological barrier, impeding the propagation through dikes of the new injected magma, which stagnates and promotes resurgence. In explaining resurgence and its related features, we provide the theoretical background to account for the transition from magma eruption to accumulation, which is essential not only to develop resurgence, but also large magma reservoirs.

AB - Conventional models for grain growth are based on the assumption that grain boundary (GB) velocity is proportional to GB mean curvature. We demonstrate via a series of molecular dynamics (MD) simulations that such a model is inadequate and that many physical phenomena occur during grain boundary migration for which this simple model is silent. We present a series of MD simulations designed to unravel GB migration phenomena and set it in a GB migration context that accounts for competing migration mechanisms, elasticity, temperature, and grain boundary crystallography. The resultant formulation is quantitative and validated through a series of atomistic simulations. The implications of this model for microstructural evolution is described. We show that consideration of GB migration mechanisms invites considerable complexity even under ideal conditions. However, that complexity also grants these systems enormous flexibility, and that flexibility is key to the decades-long success of conventional grain growth theories.

AB - The formation of endothelial lumen is fundamental to angiogenesis and essential to the oxygenation of hypoxic tissues. The molecular mechanism underlying this important process remains obscure. Here, we show that Akt activation by a Ras homolog, R-Ras, stabilizes the microtubule cytoskeleton in endothelial cells leading to endothelial lumenogenesis. The activation of Akt by the potent angiogenic factor VEGF-A does not strongly stabilize microtubules or sufficiently promote lumen formation, hence demonstrating a distinct role for the R-Ras-Akt axis. We show in mice that this pathway is important for the lumenization of new capillaries and microvessels developing in ischemic muscles to allow sufficient tissue reperfusion after ischemic injury. Our work identifies a role for Akt in lumenogenesis and the significance of the R-Ras-Akt signaling for the patency of regenerating blood vessels. PMID- 29170376 TI - Cryo-EM structure of Saccharomyces cerevisiae target of rapamycin complex 2. AB - The target of rapamycin (TOR) kinase assembles into two distinct multiprotein complexes, conserved across eukaryote evolution. In contrast to TOR complex 1 (TORC1), TORC2 kinase activity is not inhibited by the macrolide rapamycin. Here, we present the structure of Saccharomyces cerevisiae TORC2 determined by electron cryo-microscopy. TORC2 contains six subunits assembling into a 1.4 MDa rhombohedron. Tor2 and Lst8 form the common core of both TOR complexes. Avo3/Rictor is unique to TORC2, but interacts with the same HEAT repeats of Tor2 that are engaged by Kog1/Raptor in mammalian TORC1, explaining the mutual exclusivity of these two proteins. Density, which we conclude is Avo3, occludes the FKBP12-rapamycin-binding site of Tor2's FRB domain rendering TORC2 rapamycin insensitive and recessing the kinase active site. Although mobile, Avo1/hSin1 further restricts access to the active site as its conserved-region-in-the-middle (CRIM) domain is positioned along an edge of the TORC2 active-site-cleft, consistent with a role for CRIM in substrate recruitment.

AB - Animals integrate multiple sensory inputs to successfully navigate in their environments. Head direction (HD), boundary vector, grid and place cells in the entorhinal-hippocampal network form the brain's navigational system that allows to identify the animal's current location, but how the functions of these specialized neuron types are acquired remain to be understood. Here we report that activity of HD neurons is influenced by the ambulatory constraints imposed upon the animal by the boundaries of the explored environment, leading to spurious spatial information. However, in the post-subiculum, the main cortical stage of HD signal processing, HD neurons convey true spatial information in the form of border modulated activity through the integration of additional sensory modalities relative to egocentric position, unlike their driving thalamic inputs. These findings demonstrate how the combination of HD and egocentric information can be transduced into a spatial code. PMID- 29170379 TI - The influence of the solid to plasma phase transition on the generation of plasma instabilities. AB - The study of plasma instabilities is a research topic with fundamental importance since for the majority of plasma applications they are unwanted and there is always the need for their suppression. The initiating physical processes that seed the generation of plasma instabilities are not well understood in all plasma geometries and initial states of matter. For most plasma instability studies, using linear or even nonlinear magnetohydrodynamics (MHD) theory, the most crucial step is to correctly choose the initial perturbations imposed either by a predefined perturbation, usually sinusoidal, or by randomly seed perturbations as initial conditions. Here, we demonstrate that the efficient study of the seeding mechanisms of plasma instabilities requires the incorporation of the intrinsic real physical characteristics of the solid target in an electro-thermo-mechanical multiphysics study. The present proof-of-principle study offers a perspective to the understanding of the seeding physical mechanisms in the generation of plasma instabilities. PMID- 29170380 TI - Josephson emission with frequency span 1-11 THz from small Bi2Sr2CaCu2O8+delta mesa structures. AB - Mesa structures made of Bi2Sr2CaCu2O8+delta high-temperature superconductor represent stacks of atomic scale intrinsic Josephson junctions. They can be used for generation of high-frequency electromagnetic waves. Here we analyze Josephson emission from small-but-high mesas (with a small area, but containing many stacked junctions). We have found strong evidence for tunable terahertz emission with a good efficacy in a record high-frequency span 1-11 THz, approaching the theoretical upper limit for this superconductor. Emission maxima correspond to in phase cavity modes in the mesas, indicating coherent superradiant nature of the emission. We conclude that terahertz emission requires a threshold number of junctions N ~ 100. The threshold behavior is not present in the classical description of stacked Josephson junctions and suggests importance of laser-like cascade amplification of the photon number in the cavity. PMID- 29170381 TI - Feature-based learning improves adaptability without compromising precision. AB - Learning from reward feedback is essential for survival but can become extremely challenging with myriad choice options. Here, we propose that learning reward values of individual features can provide a heuristic for estimating reward values of choice options in dynamic, multi-dimensional environments. We hypothesize that this feature-based learning occurs not just because it can reduce dimensionality, but more importantly because it can increase adaptability without compromising precision of learning. We experimentally test this hypothesis and find that in dynamic environments, human subjects adopt feature based learning even when this approach does not reduce dimensionality. Even in static, low-dimensional environments, subjects initially adopt feature-based learning and gradually switch to learning reward values of individual options, depending on how accurately objects' values can be predicted by combining feature values. Our computational models reproduce these results and highlight the importance of neurons coding feature values for parallel learning of values for features and objects.

AB - Humans have a strong need to belong to social groups and a natural inclination to benefit ingroup members. Although the psychological mechanisms behind human prosociality have extensively been studied, the specific neural systems bridging group belongingness and altruistic motivation remain to be identified. Here, we used soccer fandom as an ecological framing of group membership to investigate the neural mechanisms underlying ingroup altruistic behaviour in male fans using event-related functional magnetic resonance. We designed an effort measure based on handgrip strength to assess the motivation to earn money (i) for oneself, (ii) for anonymous ingroup fans, or (iii) for a neutral group of anonymous non-fans. While overlapping valuation signals in the medial orbitofrontal cortex (mOFC) were observed for the three conditions, the subgenual cingulate cortex (SCC) exhibited increased functional connectivity with the mOFC as well as stronger hemodynamic responses for ingroup versus outgroup decisions. These findings indicate a key role for the SCC, a region previously implicated in altruistic decisions and group affiliation, in dovetailing altruistic motivations with neural valuation systems in real-life ingroup behaviour. PMID- 29170384 TI - The origin of motif families in food webs. AB - Food webs have been found to exhibit remarkable "motif profiles", patterns in the relative prevalences of all possible three-species subgraphs, and this has been related to ecosystem properties such as stability and robustness. Analysing 46 food webs of various kinds, we find that most food webs fall into one of two distinct motif families. The separation between the families is well predicted by a global measure of hierarchical order in directed networks-trophic coherence. We find that trophic coherence is also a good predictor for the extent of omnivory, defined as the tendency of species to feed on multiple trophic levels. We compare our results to a network assembly model that admits tunable trophic coherence via a single free parameter. The model is able to generate food webs in either of the two families by varying this parameter, and correctly classifies almost all the food webs in our database. This is in contrast with the two most popular food web models, the generalized cascade and niche models, which can only generate food webs within a single motif family. Our findings suggest the importance of trophic coherence in modelling local preying patterns in food webs. PMID- 29170385 TI - Temperature dependence of the single photon emission from interface-fluctuation GaN quantum dots. AB - The temperature dependent single photon emission statistics of interface fluctuation GaN quantum dots are reported. Quantum light emission is confirmed at temperatures up to ~77 K, by which point the background emission degrades the emission purity and results in a measured g(2) (0) in excess of 0.5. A discussion on the extent of the background contamination is also given through comparison to extensive data taken under various ambient and experimental conditions, revealing that the quantum dots themselves are emitting single photons with high purity. PMID- 29170387 TI - Microstructural Development in a Laser-Remelted Al-Zn-Si-Mg Coating. AB - In the last five decades, there has been intense development in the field of Zn Al galvanic coating modification. Recently, Mg was added to improve corrosion properties. Further improvements to the coating are possible with additional laser surface treatment. In this article, we focus on remelting the Al-Zn-Mg-Si layer, using a diode laser with a wide-beam format, concentrating on the microstructure development during extreme cooling rates. Laser remelting of the Al-Zn-Mg-Si coating and rapid self-quenching produces a finer grain size, and a microstructure that is substantially refined and homogenized with respect to the phase distribution. Using EBSD results, we are able to understand microstructure modification. The laser modified coating has some porosity and intergranular cracking which are difficult to avoid, however this does not seem to be detrimental to mechanical properties, such as ductility on bending. The newly developed technology has a high potential for improved corrosion performance due to highly refined microstructure. PMID- 29170388 TI - Influence of Stage Cooling Method on Pore Architecture of Biomimetic Alginate Scaffolds. AB - Porous scaffold is widely used in the field of tissue engineering. However, the anisotropic structure of actual extracellular matrix (ECM) of human tissue pose a challenge to the scaffold structure that pore size should be changed in gradient. Here we report a stage cooling method to fabricate alginate scaffold with gradient pores. Eight cooling models were set according to different temperature steps, different initial temperature, and different time duration. The thermal characterization of solution during cooling process were recorded and scaffold morphology were observed. The results revealed that the temperature steps mainly affected pore shape, while the initial temperature and time duration mainly affected pore size. By altering the initial temperature and time duration, scaffold exhibited cellular and gradually enlarged pores on the vertical axial direction (10-65 MUm at base, 50-141 MUm at top). With this stage cooling method, pore shape and pore size could be easily tailored and scaffold with gradient structure could be fabricated. PMID- 29170386 TI - Glucocorticoid-induced phosphorylation by CDK9 modulates the coactivator functions of transcriptional cofactor GRIP1 in macrophages. AB - The glucocorticoid (GC) receptor (GR) suppresses inflammation by activating anti inflammatory and repressing pro-inflammatory genes. GR-interacting protein-1 (GRIP1) is a GR corepressor in macrophages, however, whether GRIP1 mediates GR activated transcription, and what dictates its coactivator versus corepressor properties is unknown. Here we report that GRIP1 loss in macrophages attenuates glucocorticoid induction of several anti-inflammatory targets, and that GC treatment of quiescent macrophages globally directs GRIP1 toward GR binding sites dominated by palindromic GC response elements (GRE), suggesting a non-redundant GRIP1 function as a GR coactivator. Interestingly, GRIP1 is phosphorylated at an N-terminal serine cluster by cyclin-dependent kinase-9 (CDK9), which is recruited into GC-induced GR:GRIP1:CDK9 hetero-complexes, producing distinct GRE-specific GRIP1 phospho-isoforms. Phosphorylation potentiates GRIP1 coactivator but, remarkably, not its corepressor properties. Consistently, phospho-GRIP1 and CDK9 are not detected at GR transrepression sites near pro-inflammatory genes. Thus, GR restricts actions of its own coregulator via CDK9-mediated phosphorylation to a subset of anti-inflammatory genes. PMID- 29170389 TI - Ultra-wideband polarization conversion metasurface and its application cases for antenna radiation enhancement and scattering suppression. AB - A double-layer complementary metasurface (MS) with ultra-wideband polarization conversion is presented. Then, we propose two application cases by applying the polarization conversion structures to aperture coupling patch antenna (ACPA). Due to the existence of air-filled gap of ACPA, air substrate and dielectric substrate are used to construct the double-layer MS. The polarization conversion bandwidth is broadened toward low-frequency range. Subsequently, two application cases of antenna are proposed and investigated. The simultaneous improvement of radiation and scattering performance of antenna is normally considered as a contradiction. Gratifyingly, the contradiction is addressed in these two application cases. According to different mechanism of scattering suppression (i.e., polarization conversion and phase cancellation), the polarization conversion structures are utilized to construct uniform and orthogonal arrangement configurations. And then, the configurations are integrated into ACPA and two different kinds of metasurface-based (MS-based) ACPA are formed. Radiation properties of the two MS-based ACPAs are improved by optimizing the uniform and orthogonal arrangement configurations. The measured results suggest that ultra-wideband polarization conversion properties of the MS are achieved and radiation enhancement and scattering suppression of the two MS-based ACPAs are obtained. These results demonstrate that we provide novel approach to design high performance polarization conversion MS and MS-based devices. PMID- 29170390 TI - Systems analysis of latent HIV reversal reveals altered stress kinase signaling and increased cell death in infected T cells. AB - Viral latency remains the most significant obstacle to HIV eradication. Clinical strategies aim to purge the latent CD4+ T cell reservoir by activating viral expression to induce death, but are undercut by the inability to target latently infected cells. Here we explored the acute signaling response of latent HIV infected CD4+ T cells to identify dynamic phosphorylation signatures that could be targeted for therapy. Stimulation with CD3/CD28, PMA/ionomycin, or latency reversing agents prostratin and SAHA, yielded increased phosphorylation of IkappaBalpha, ERK, p38, and JNK in HIV-infected cells across two in vitro latency models. Both latent infection and viral protein expression contributed to changes in perturbation-induced signaling. Data-driven statistical models calculated from the phosphorylation signatures successfully classified infected and uninfected cells and further identified signals that were functionally important for regulating cell death. Specifically, the stress kinase pathways p38 and JNK were modified in latently infected cells, and activation of p38 and JNK signaling by anisomycin resulted in increased cell death independent of HIV reactivation. Our findings suggest that altered phosphorylation signatures in infected T cells provide a novel strategy to more selectively target the latent reservoir to enhance eradication efforts. PMID- 29170391 TI - Preventive effect of Agnucastoside C against Isoproterenol-induced myocardial injury. AB - An iridoid glycoside, agnucastoside C (ACC) was isolated from the leaves of Moringa oliefera and its cardio protective potential was investigated in adult rats by examining the effects of this test compound, ACC at 30 mg/kg for 14 days in isoproterenol (100 mg/kg)-induced myocardial injury. Isoproterenol (ISO) administration induced the myocardial injury as evidenced by the altered ECG pattern with ST-segment elevation and an increase in the levels of cardiac injury markers including troponin-I, creatine kinase-MB, alanine transaminase, aspartate transaminase, lactate dehydrogenase; inflammatory markers, interleukine-6 and tumor necrosis factor. In this group, there was also an increase in cardiac lipid peroxidation and a decrease in cellular antioxidants. However, pretreatment with ACC maintained the normal ECG pattern and nearly normal levels of all the cardiac markers in ISO-induced animals. Electron microscopic and histological studies also showed marked reduction in ISO-induced cardiac damages including infarct size by ACC. Analysis by 2-DE revealed the involvement of 19 different cardiac proteins, associated with energy metabolism, oxidative stress and maintenance of cytoskeleton. The expression of those proteins were altered by ISO, but maintained in ACC pretreated rats. Our findings reveal the potential of isolated ACC in the prevention of myocardial damage.

AB - High dispersal of Lepidoptera larvae between non-Bt and Bt cotton plants can favour the evolution of insect resistance; however, information on host acceptance of neonates in tropical transgenic crops is scarce. Therefore, the purposes of this study were as follows: (i) to investigate the feeding behaviour of susceptible and Cry1F-resistant strains of Spodoptera frugiperda (J.E. Smith) on Bt and non-Bt cotton (Gossypium hirsutum L.) varieties and (ii) to understand the possible effects of cotton field contamination on the dispersal and infestation capacity of S. frugiperda larvae by using an individual-based model. The main results of this paper are as follows: (1) the highest post-feeding larval dispersal of the Cry1F-resistant strain occurred at an exposure time of 18 24 h; (2) via video tracking assays, we found that the least distance moved was by larvae resistant to Cry1F on non-Bt cotton; and (3) the model indicated differences in mobility capacity between Bt and non-Bt cotton. We conclude that resistant neonates exhibit sedentary behaviour. Our report represents the first findings concerning the fitness cost of larval behaviour traits of S. frugiperda associated with Cry1F resistance in Brazilian populations. PMID- 29170393 TI - An in vivo biosensing, biomimetic electrochemical transistor with applications in plant science and precision farming. AB - The in vivo monitoring of key plant physiology parameters will be a key enabler of precision farming. Here, a biomimetic textile-based biosensor, which can be inserted directly into plant tissue is presented: the device is able to monitor, in vivo and in real time, variations in the solute content of the plant sap. The biosensor has no detectable effect on the plant's morphology even after six weeks of continuous operation. The continuous monitoring of the sap electrolyte concentration in a growing tomato plant revealed a circadian pattern of variation. The biosensor has the potential to detect the signs of abiotic stress, and therefore might be exploited as a powerful tool to study plant physiology and to increase tomato growth sustainability. Also, it can continuously communicate the plant health status, thus potentially driving the whole farm management in the frame of smart agriculture. PMID- 29170394 TI - Quantifying protein densities on cell membranes using super-resolution optical fluctuation imaging. AB - Quantitative approaches for characterizing molecular organization of cell membrane molecules under physiological and pathological conditions profit from recently developed super-resolution imaging techniques. Current tools employ statistical algorithms to determine clusters of molecules based on single molecule localization microscopy (SMLM) data. These approaches are limited by the ability of SMLM techniques to identify and localize molecules in densely populated areas and experimental conditions of sample preparation and image acquisition. We have developed a robust, model-free, quantitative clustering analysis to determine the distribution of membrane molecules that excels in densely labeled areas and is tolerant to various experimental conditions, i.e. multiple-blinking or high blinking rates. The method is based on a TIRF microscope followed by a super-resolution optical fluctuation imaging (SOFI) analysis. The effectiveness and robustness of the method is validated using simulated and experimental data investigating nanoscale distribution of CD4 glycoprotein mutants in the plasma membrane of T cells. PMID- 29170396 TI - An estimate of diapycnal nutrient fluxes to the euphotic zone in the Florida Straits. AB - A recent hydrographic survey of the Florida Current at 27 degrees N revealed an enhanced upward flux of nutrients along the Florida coast. Geostrophic flow of the Gulf Stream through the narrow Florida Straits causes an uplift of the nutricline toward its western edge, shoaling the mixed layers into the base of the euphotic zone. At a nearshore station, nitrate, phosphate, and silicate concentrations reached 19, 1.4, and 10 uM, respectively, at a water depth of 27 m. Furthermore, nutrient vertical gradients below the mixed layer increased with decreasing seafloor depth toward the Florida coast. The estimated vertical eddy diffusive nutrient fluxes across diapycnal surfaces reached 0.40-83.7, 0.03-6.24, and 0.24-45.5 mmol m-2 d-1 for nitrate, phosphate, and silicate, respectively, along the shore. Estimated fluxes span a wide range due to the range of diffusivity measured. The lower end of estimated fluxes are comparable to open ocean values, but higher end of estimates are two orders of magnitude greater than those observed in open ocean. The diapycnal nutrient fluxes declined rapidly offshore as a result of decreasing vertical gradients of nutrient concentration. PMID- 29170395 TI - Oncogenic PIK3CA induces centrosome amplification and tolerance to genome doubling. AB - Mutations in PIK3CA are very frequent in cancer and lead to sustained PI3K pathway activation. The impact of acute expression of mutant PIK3CA during early stages of malignancy is unknown. Using a mouse model to activate the Pik3ca H1047R hotspot mutation in the heterozygous state from its endogenous locus, we here report that mutant Pik3ca induces centrosome amplification in cultured cells (through a pathway involving AKT, ROCK and CDK2/Cyclin E-nucleophosmin) and in mouse tissues, and increased in vitro cellular tolerance to spontaneous genome doubling. We also present evidence that the majority of PIK3CA H1047R mutations in the TCGA breast cancer cohort precede genome doubling. These previously unappreciated roles of PIK3CA mutation show that PI3K signalling can contribute to the generation of irreversible genomic changes in cancer. While this can limit the impact of PI3K-targeted therapies, these findings also open the opportunity for therapeutic approaches aimed at limiting tumour heterogeneity and evolution. PMID- 29170397 TI - Methylomic and phenotypic analysis of the ModH5 phasevarion of Helicobacter pylori. AB - The Helicobacter pylori phase variable gene modH, typified by gene HP1522 in strain 26695, encodes a N6-adenosine type III DNA methyltransferase. Our previous studies identified multiple strain-specific modH variants (modH1 - modH19) and showed that phase variation of modH5 in H. pylori P12 influenced expression of motility-associated genes and outer membrane protein gene hopG. However, the ModH5 DNA recognition motif and the mechanism by which ModH5 controls gene expression were unknown. Here, using comparative single molecule real-time sequencing, we identify the DNA site methylated by ModH5 as 5'-Gm6ACC-3'. This motif is vastly underrepresented in H. pylori genomes, but overrepresented in a number of virulence genes, including motility-associated genes, and outer membrane protein genes. Motility and the number of flagella of H. pylori P12 wild type were significantly higher than that of isogenic modH5 OFF or DeltamodH5 mutants, indicating that phase variable switching of modH5 expression plays a role in regulating H. pylori motility phenotypes. Using the flagellin A (flaA) gene as a model, we show that ModH5 modulates flaA promoter activity in a GACC methylation-dependent manner. These findings provide novel insights into the role of ModH5 in gene regulation and how it mediates epigenetic regulation of H. pylori motility. PMID- 29170399 TI - Polarization of the Majorana quasiparticles in the Rashba chain. AB - We demonstrate that the selective equal-spin Andreev reflection (SESAR) spectroscopy can be used in STM experiments to distinguish the zero-energy Majorana quasiparticles from the ordinary fermionic states of the Rashba chain. Such technique, designed for probing the p-wave superconductivity, could be applied to the intersite pairing of equal-spin electrons in the chain of magnetic Fe atoms deposited on the superconducting Pb substrate. Our calculations of the effective pairing amplitude for individual spin components imply the magnetically polarized Andreev conductance, which can be used to 'filter' the Majorana quasiparticles from the ordinary in-gap states, although the pure spin current (i.e., perfect polarization) is impossible. PMID- 29170398 TI - Arabidopsis RSS1 Mediates Cross-Talk Between Glucose and Light Signaling During Hypocotyl Elongation Growth. AB - Plants possess exuberant plasticity that facilitates its ability to adapt and survive under challenging environmental conditions. The developmental plasticity largely depends upon cellular elongation which is governed by a complex network of environmental and phytohormonal signals. Here, we report role of glucose (Glc) and Glc-regulated factors in controlling elongation growth and shade response in Arabidopsis. Glc controls shade induced hypocotyl elongation in a dose dependent manner. We have identified a Glc repressed factor REGULATED BY SUGAR AND SHADE1 (RSS1) encoding for an atypical basic helix-loop-helix (bHLH) protein of unknown biological function that is required for normal Glc actions. Phenotype analysis of mutant and overexpression lines suggested RSS1 to be a negative regulator of elongation growth. RSS1 affects overall auxin homeostasis. RSS1 interacts with the elongation growth-promoting proteins HOMOLOG OF BEE2 INTERACTING WITH IBH 1 (HBI1) and BR ENHANCED EXPRESSION2 (BEE2) and negatively affects the transcription of their downstream targets such as YUCs, INDOLE-3-ACETIC ACID INDUCIBLE (IAAs), LONG HYPOCOTYL IN FAR-RED1 (HFR1), HOMEOBOX PROTEIN 2 (ATHB2), XYLOGLUCAN ENDOTRANSGLUCOSYLASE/HYDROLASES (XTHs) and EXPANSINS. We propose, Glc signals might maintain optimal hypocotyl elongation under multiple signals such as light, shade and phytohormones through the central growth regulatory bHLH/HLH module. PMID- 29170400 TI - Host STING-dependent MDSC mobilization drives extrinsic radiation resistance. AB - Radiotherapy induces and promotes innate and adaptive immunity in which host STING plays an important role. However, radioresistance in irradiated tumors can also develop, resulting in relapse. Here we report a mechanism by which extrinsic resistance develops after local ablative radiation that relies on the immunosuppressive action of STING. The STING/type I interferon pathway enhances suppressive inflammation in tumors by recruiting myeloid cells in part via the CCR2 pathway. Germ-line knockouts of CCR2 or treatment with an anti-CCR2 antibody results in blockade of radiation-induced MDSC infiltration. Treatment with anti CCR2 antibody alleviates immunosuppression following activation of the STING pathway, enhancing the anti-tumor effects of STING agonists and radiotherapy. We propose that radiation-induced STING activation is immunosuppressive due to (monocytic) M-MDSC infiltration, which results in tumor radioresistance. Furthermore, the immunosuppressive effects of radiotherapy and STING agonists can be abrogated in humans by a translational strategy involving anti-CCR2 antibody treatment to improve radiotherapy. PMID- 29170401 TI - Functional diversity of topological modules in human protein-protein interaction networks. AB - A large-scale molecular interaction network of protein-protein interactions (PPIs) enables the automatic detection of molecular functional modules through a computational approach. However, the functional modules that are typically detected by topological community detection algorithms may be diverse in functional homogeneity and are empirically considered to be default functional modules. Thus, a significant challenge that has been described but not elucidated is investigating the relationship between topological modules and functional modules. We systematically investigated this issue by initially using seven widely used community detection algorithms to partition the PPI network into communities. Four homogeneity measures were subsequently implemented to evaluate the functional homogeneity of protein community. We determined that a significant portion of topological modules with heterogeneous functionality exists and should be further investigated; moreover, these findings indicated that topologically based functional module detection approaches must be reconsidered. Furthermore, we found that the functional homogeneity of topological modules is positively correlated with their edge densities, degree of association with diseases and general Gene Ontology (GO) terms. Thus, topologically based module detection approaches should be used with caution in the identification of functional modules with high homogeneity.

PMID- 29170403 TI - Coalescent-based delimitation outperforms distance-based methods for delineating less divergent species: the case of Kurixalus odontotarsus species group. AB - Few empirical studies have compared coalescent-based methods to distance-based methods for delimitation of less divergent species. In this study, we used two coalescent-based (BFD and BPP) and two distance-based barcoding (ABGD and jMOTU) methods to delimit closely related species in the Kurixalus odontotarsus species group. Phylogenetic analyses revealed that the K. odontotarsus species group comprises 11 distinct maternal clades with strong support values. Based on the genetic and morphological evidences, we consider that species diversity in the K. odontotarsus species group was underestimated and the 11 clades represent 11 species, of which six are unnamed. The coalescent-based delimitations decisively supported the scenario of 11-species corresponding to the 11 clades. However, the distance-based ABGD only obtained 3-6 candidate species, which is not consistent with morphological evidence. These results indicate that BFD and BPP are more conservative than ABGD to false negatives (lumping). Method of fixed threshold (jMOTU) may obtain a resolution similar to that inferred by BFD and BPP, but it severely relies on subjective choice of the threshold and lacks statistical support. We consider that coalescent-based BFD and BPP approaches outperform distance-based methods for delineation of less divergent species. PMID- 29170404 TI - A galactic microquasar mimicking winged radio galaxies. AB - A subclass of extragalactic radio sources known as winged radio galaxies has puzzled astronomers for many years. The wing features are detected at radio wavelengths as low-surface-brightness radio lobes that are clearly misaligned with respect to the main lobe axis. Different models compete to account for these peculiar structures. Here, we report observational evidence that the parsec-scale radio jets in the Galactic microquasar GRS 1758-258 give rise to a Z-shaped radio emission strongly reminiscent of the X and Z-shaped morphologies found in winged radio galaxies. This is the first time that such extended emission features are observed in a microquasar, providing a new analogy for its extragalactic relatives. From our observations, we can clearly favour the hydrodynamic backflow interpretation against other possible wing formation scenarios. Assuming that physical processes are similar, we can extrapolate this conclusion and suggest that this mechanism could also be at work in many extragalactic cases. PMID- 29170405 TI - The Robustness and the Doubly-Preferential Attachment Simulation of the Consensus Connectome Dynamics of the Human Brain. AB - Consensus Connectome Dynamics (CCD) is a remarkable phenomenon of the human connectomes (braingraphs) that was discovered by continuously decreasing the minimum confidence-parameter at the graphical interface of the Budapest Reference Connectome Server, which depicts the cerebral connections of n = 418 subjects with a frequency-parameter k: For any k = 1, 2, ..., n one can view the graph of the edges that are present in at least k connectomes. If parameter k is decreased one-by-one from k = n through k = 1 then more and more edges appear in the graph, since the inclusion condition is relaxed. The surprising observation is that the appearance of the edges is far from random: it resembles a growing, complex structure. We hypothesize that this growing structure copies the axonal development of the human brain. Here we show the robustness of the CCD phenomenon: it is almost independent of the particular choice of the set of underlying connectomes. This result shows that the CCD phenomenon is most likely a biological property of the human brain and not just a property of the data sets examined. We also present a simulation that well-describes the growth of the CCD structure: in our random graph model a doubly-preferential attachment distribution is found to mimic the CCD.

AB - The prognosis and prediction of adjuvant chemotherapy (ACT) response in early stage non-small cell lung cancer (NSCLC) patients remain poor in this era of personalized medicine. We hypothesize that extracellular matrix (ECM)-associated components could be potential markers for better diagnosis and prognosis due to their differential expression in 1,943 primary NSCLC tumors as compared to 303 normal lung tissues. Here we develop a 29-gene ECM-related prognostic and predictive indicator (EPPI). We validate a robust performance of the EPPI risk scoring system in multiple independent data sets, comprising a total of 2,071 early-stage NSCLC tumors. Patients are stratified according to the universal cutoff score based on the EPPI when applied in the clinical setting; the low-risk group has significantly better survival outcome. The functional EPPI gene set represents a potential genomic tool to improve patient selection in early-stage NSCLC to further derive the best benefits of ACT and prevent unnecessary treatment or ACT-associated morbidity. PMID- 29170407 TI - Higher risk sexual behaviour is associated with unawareness of HIV-positivity and lack of viral suppression - implications for Treatment as Prevention. AB - Efficacy of Treatment as Prevention Strategy depends on a variety of factors including individuals' likelihood to test and initiate treatment, viral load and sexual behaviour. We tested the hypothesis that people with higher risk sexual behaviour are less likely to know their HIV-positive status and be virologically suppressed. A cross-sectional population-based survey of individuals aged 15-59 years old was conducted in 2013 in KwaZulu-Natal, South Africa. A two-stage cluster probability sampling was used. After adjustment for age and sex, lack of awareness of HIV-positivity was strongly associated with having more than one sexual partner in the preceding year (aOR: 2.1, 95%CI: 1.5-3.1). Inconsistent condom use was more common in individuals with more than one sexual partner (aOR: 16.6, 95%CI: 7.6-36.7) and those unaware (aOR: 3.7, 95%CI: 2.6-5.4). Among people aware of their HIV-positivity, higher risk sexual behaviour was associated with lack of viral suppression (aOR: 2.2, 95%CI: 1.1-4.5). Risky sexual behaviour seems associated with factors linked to poor health-seeking behaviour which may have negative implications for HIV testing and Treatment as Prevention. Innovative strategies, driven by improved epidemiological and anthropological understanding, are needed to enable comprehensive approaches to HIV prevention. PMID- 29170408 TI - Identification of the Binding Sites on Rab5 and p110beta Phosphatidylinositol 3 kinase. AB - Rab5 is a small monomeric GTPase that mediates protein trafficking during endocytosis. Inactivation of Rab5 by GTP hydrolysis causes a conformational change that masks binding sites on its "switch regions" from downstream effectors. The p85 subunit of phosphatidylinositol 3-kinase (PI3K) is a GTPase activating protein (GAP) towards Rab5. Whereas p85 can bind with both Rab5-GTP and Rab5-GDP, the PI3K catalytic subunit p110beta binds only Rab5-GTP, suggesting it interacts with the switch regions. Thus, the GAP functions of the catalytic arginine finger (from p85) and switch region stabilization (from p110beta) may be provided by both proteins, acting together. To identify the Rab5 residues involved in binding p110beta, residues in the Rab5 switch regions were mutated. A stabilized recombinant p110 protein, where the p85-iSH2 domain was fused to p110 (alpha or beta) was used in binding experiments. Eleven Rab5 mutants, including E80R and H83E, showed reduced p110beta binding. The Rab5 binding site on p110beta was also resolved through mutation of p110beta in its Ras binding domain, and includes residues I234, E238 and Y244. This is a second region within p110beta important for Rab5 binding. The Rab5-GTP:p110beta interaction may be further elucidated through the characterization of these non-binding mutants in cells.

AB - Nowadays, complicated topological defects enable many experimental manipulations and configurational simulations of active soft matter for optical and photonic applications. Investigation of topological defects in soft anisotropic materials enables one to better understand three-dimensional orientation fields in cholesteric liquid crystals. Here, we describe optical properties of bistable bubble domain (BD) texture torons in a thin layer of cholesteric liquid crystal (CLC), frustrated by homeotropic anchoring conditions, and reliably switchable by a random process. The control of macroscopic optical density and diffraction efficiency of the BD texture is demonstrated by a selection of a confinement ratio of the CLC. Experimentally reconstructed CLC director profile reveals the topology of BD torons allowing consideration of naturally occurring BD texture for applications in optical and photonic devices, which are bistably switchable between active and transparent optical states. PMID- 29170410 TI - Endothelial cell-surface tissue transglutaminase inhibits neutrophil adhesion by binding and releasing nitric oxide. AB - Nitric oxide (NO) produced by endothelial cells in response to cytokines displays anti-inflammatory activity by preventing the adherence, migration and activation of neutrophils. The molecular mechanism by which NO operates at the blood endothelium interface to exert anti-inflammatory properties is largely unknown. Here we show that on endothelial surfaces, NO is associated with the sulfhydryl rich protein tissue transglutaminase (TG2), thereby endowing the membrane surfaces with anti-inflammatory properties. We find that tumor necrosis factor alpha-stimulated neutrophil adherence is opposed by TG2 molecules that are bound to the endothelial surface. Alkylation of cysteine residues in TG2 or inhibition of endothelial NO synthesis renders the surface-bound TG2 inactive, whereas specific, high affinity binding of S-nitrosylated TG2 (SNO-TG2) to endothelial surfaces restores the anti-inflammatory properties of the endothelium, and reconstitutes the activity of endothelial-derived NO. We also show that SNO-TG2 is present in healthy tissues and that it forms on the membranes of shear activated endothelial cells. Thus, the anti-inflammatory mechanism that prevents neutrophils from adhering to endothelial cells is identified with TG2 S nitrosylation at the endothelial cell-blood interface. PMID- 29170411 TI - Flavonoids from Pterogyne nitens Inhibit Hepatitis C Virus Entry. AB - Hepatitis C virus (HCV) is one of the leading causes of liver diseases and transplantation worldwide. The current available therapy for HCV infection is based on interferon-alpha, ribavirin and the new direct-acting antivirals (DAAs), such as NS3 protease and NS5B polymerase inhibitors. However, the high costs of drug design, severe side effects and HCV resistance presented by the existing treatments demonstrate the need for developing more efficient anti-HCV agents. This study aimed to evaluate the antiviral effects of sorbifolin (1) and pedalitin (2), two flavonoids from Pterogyne nitens on the HCV replication cycle. These compounds were investigated for their anti-HCV activities using genotype 2a JFH-1 subgenomic replicons and infectious virus systems. Flavonoids 1 and 2 inhibited virus entry up to 45.0% and 78.7% respectively at non-cytotoxic concentrations. The mechanism of the flavonoid 2 block to virus entry was demonstrated to be by both the direct action on virus particles and the interference on the host cells. Alternatively, the flavonoid 1 activity was restricted to its virucidal effect. Additionally, no inhibitory effects on HCV replication and release were observed by treating cells with these flavonoids. These data are the first description of 1 and 2 possessing in vitro anti-HCV activity. PMID- 29170412 TI - Ischemic Postconditioning Protects Against Intestinal Ischemia/Reperfusion Injury via the HIF-1alpha/miR-21 Axis. AB - Intestinal ischemia/reperfusion (I/R) can lead to tissue damage associated with inflammation and mucosal apoptosis. Ischemic postconditioning (IPostC), a series of repeated, brief, intermittent periods of ischemia and reperfusion, has beneficial effects against I/R-induced injury in the heart and intestine, although the underlying mechanisms for these effects remain unclear. We evaluated the involvement of microRNA-21 (miR-21) in the protective effects of IPostC in a rat model of I/R induced by superior mesenteric artery occlusion and reopening. IPostC decreased I/R injury and suppressed apoptosis in the intestinal tissues concomitant with the induction of hypoxia inducible factor 1 alpha (HIF-1alpha) and the upregulation of miR-21. In vitro experiments in the intestinal epithelial cell line IEC-6 showed that hypoxia induced miR-21 and this effect was abolished by silencing HIF1-alpha, confirming the induction of miR-21 by HIF1-alpha, HIF1 alpha or miR-21 inhibition exacerbated I/R induced apoptosis, and programmed cell death 4 (PDCD4) and Fas-L was involved in miR-21 mediated anti-apoptotic effects on intestinal epithelial cells. Knockdown of miR-21 or inhibition of HIF1-alpha abolished the IPostC-mediated attenuation of intestinal injury and apoptosis and the downregulation of PDCD4 and Fas-L. A potential mechanism underlying the protective effect of IPostC may therefore involve the induction of miR-21 by HIF1 alpha and the attenuation of apoptosis via the downregulation of PDCD4 and Fas-L. PMID- 29170414 TI - Tailoring the structural, morphological, optical and dielectric properties of lead iodide through Nd3+ doping. AB - Hexagonal single crystal nanosheets of Nd3+ doped PbI2 were effortlessly synthesized via microwave-assisted technique under a power of 700 W and in a duration of 15 minutes with a homogeneous morphology. X-ray diffraction, energy dispersive X-ray spectroscope, scanning electron microscope, FT-Raman, UV Visible, photoluminescence and dielectric measurement were employed to study the product. High purity, single phase and presence of Nd3+ doping was confirmed. SEM study confirm the formation of nanorods and single crystal nanosheets of very few nanometers in size. Robust vibrational analysis has been carried out and the observed bands are assigned to the vibration modes of E21, A11, A12, 2E21 and 2E11, respectively. These bands are red-shifted when compare to the corresponding bulk values which indicate relaxed nanostructure formation and occurrence of confinement effect. The thickness of the synthesized single crystal nanosheets are found to be in the range of ~20 to 30 nm. The energy band gap was calculated and found to be 3.35, 3.34, 3.42 and 3.39 eV for pure, 1, 3 and 5% Nd3+ doped lead iodide, respectively. The clear blue luminescence has been observed at 440 nm and 466 nm when excited at 250 nm and 280 nm respectively. Dielectric and ac electrical conductivity was also measured and discussed. PMID- 29170413 TI - MYC regulates ductal-neuroendocrine lineage plasticity in pancreatic ductal adenocarcinoma associated with poor outcome and chemoresistance. AB - Intratumoral phenotypic heterogeneity has been described in many tumor types, where it can contribute to drug resistance and disease recurrence. We analyzed ductal and neuroendocrine markers in pancreatic ductal adenocarcinoma, revealing heterogeneous expression of the neuroendocrine marker Synaptophysin within ductal lesions. Higher percentages of Cytokeratin-Synaptophysin dual positive tumor cells correlate with shortened disease-free survival. We observe similar lineage marker heterogeneity in mouse models of pancreatic ductal adenocarcinoma, where lineage tracing indicates that Cytokeratin-Synaptophysin dual positive cells arise from the exocrine compartment. Mechanistically, MYC binding is enriched at neuroendocrine genes in mouse tumor cells and loss of MYC reduces ductal neuroendocrine lineage heterogeneity, while deregulated MYC expression in KRAS mutant mice increases this phenotype. Neuroendocrine marker expression is associated with chemoresistance and reducing MYC levels decreases gemcitabine induced neuroendocrine marker expression and increases chemosensitivity. Altogether, we demonstrate that MYC facilitates ductal-neuroendocrine lineage plasticity in pancreatic ductal adenocarcinoma, contributing to poor survival and chemoresistance. PMID- 29170415 TI - Antagonistic bacteria disrupt calcium homeostasis and immobilize algal cells. AB - Photosynthetic unicellular organisms, known as microalgae, are key contributors to carbon fixation on Earth. Their biotic interactions with other microbes shape aquatic microbial communities and influence the global photosynthetic capacity. So far, limited information is available on molecular factors that govern these interactions. We show that the bacterium Pseudomonas protegens strongly inhibits the growth and alters the morphology of the biflagellated green alga Chlamydomonas reinhardtii. This antagonistic effect is decreased in a bacterial mutant lacking orfamides, demonstrating that these secreted cyclic lipopeptides play an important role in the algal-bacterial interaction. Using an aequorin Ca2+ reporter assay, we show that orfamide A triggers an increase in cytosolic Ca2+ in C. reinhardtii and causes deflagellation of algal cells. These effects of orfamide A, which are specific to the algal class of Chlorophyceae and appear to target a Ca2+ channel in the plasma membrane, represent a novel biological activity for cyclic lipopeptides. PMID- 29170417 TI - Remotely Triggered Locomotion of Hydrogel Mag-bots in Confined Spaces. AB - In this study, soft hydrogel crawlers with remote magnetic-responsive motility in confined spaces have been developed. Inspired by the motion of maggots, the hydrogel crawlers can reversibly contract and elongate their body controlled by repeatedly switching on/off an alternating magnetic field. Based on the cyclic deformation, the hydrogel crawlers can move peristaltically in a confined space that is coated with asymmetric micro-patterns. The dependence of the hydrogel motility on the pattern structures and lubrication is characterized using experimental measurements. Such a hydrogel system pioneers the study of active motile systems in porous media and has the potential to impact the fields of targeted drug delivery and active actuators. PMID- 29170416 TI - Ultrafast non-radiative dynamics of atomically thin MoSe2. AB - Photo-induced non-radiative energy dissipation is a potential pathway to induce structural-phase transitions in two-dimensional materials. For advancing this field, a quantitative understanding of real-time atomic motion and lattice temperature is required. However, this understanding has been incomplete due to a lack of suitable experimental techniques. Here, we use ultrafast electron diffraction to directly probe the subpicosecond conversion of photoenergy to lattice vibrations in a model bilayered semiconductor, molybdenum diselenide. We find that when creating a high charge carrier density, the energy is efficiently transferred to the lattice within one picosecond. First-principles nonadiabatic quantum molecular dynamics simulations reproduce the observed ultrafast increase in lattice temperature and the corresponding conversion of photoenergy to lattice vibrations. Nonadiabatic quantum simulations further suggest that a softening of vibrational modes in the excited state is involved in efficient and rapid energy transfer between the electronic system and the lattice. PMID- 29170418 TI - Gene Therapy Restores Mfrp and Corrects Axial Eye Length. AB - Hyperopia (farsightedness) is a common and significant cause of visual impairment, and extreme hyperopia (nanophthalmos) is a consequence of loss-of function MFRP mutations. MFRP deficiency causes abnormal eye growth along the visual axis and significant visual comorbidities, such as angle closure glaucoma, cystic macular edema, and exudative retinal detachment. The Mfrp rd6 /Mfrp rd6 mouse is used as a pre-clinical animal model of retinal degeneration, and we found it was also hyperopic. To test the effect of restoring Mfrp expression, we delivered a wild-type Mfrp to the retinal pigmented epithelium (RPE) of Mfrp rd6 /Mfrp rd6 mice via adeno-associated viral (AAV) gene therapy. Phenotypic rescue was evaluated using non-invasive, human clinical testing, including fundus auto fluorescence, optical coherence tomography, electroretinography, and ultrasound. These analyses showed gene therapy restored retinal function and normalized axial length. Proteomic analysis of RPE tissue revealed rescue of specific proteins associated with eye growth and normal retinal and RPE function. The favorable response to gene therapy in Mfrp rd6 /Mfrp rd6 mice suggests hyperopia and associated refractive errors may be amenable to AAV gene therapy.

PMID- 29170419 TI - PDGFR Signaling Mediates Hyperproliferation and Fibrotic Responses of Subsynovial Connective Tissue Cells in Idiopathic Carpal Tunnel Syndrome. AB - Fibrosis of the subsynovial connective tissue (SSCT) is a pathognomonic change in carpal tunnel syndrome (CTS). Identification of molecular targets and anti fibrotic therapies could provide new treatment strategies for CTS. The contribution of SSCT cells to fibrosis and the signaling pathways that initiate and aggravate fibrosis in CTS remain unknown. Here we report that platelet derived growth factor receptor alpha (PDGFRalpha) positive ( + ) cells accumulate in CTS SSCT and that the presence of fibrotic growth factor, PDGF-AA, results in increased proliferation of PDGFRalpha+ cells via PI3K/Akt signaling pathway. Although PI3K inhibition decreased proliferation, there was no change in fibrosis related gene expression. Indeed, protein levels of fibrosis signaling mediator TGF-beta remained the same and the second messenger, Smad2/3, accumulated in the nucleus. In contrast AMP-activated protein kinase (AMPK) activation, which can be induced with metformin and AICAR inhibited proliferation, TGF-beta expression, and altered cell morphology in SSCT cells. Further we show that AMPK activation by metformin reduced collagen III levels and the ratio of Collagen I to Collagen III. Both AICAR and metformin reduced F-actin and significantly reduced the fiber cross alignment. Our results suggest that PDGFRa signaling may be an important fibrosis target and that activators of AMPK, may be an important therapeutic approach for treating CTS. PMID- 29170421 TI - Resident Microbiome Disruption with Antibiotics Enhances Virulence of a Colonizing Pathogen. AB - There is growing evidence that symbiotic microbes play key roles in host defense, but less is known about how symbiotic microbes mediate pathogen-induced damage to hosts. Here, we use a natural wildlife disease system, house finches and the conjunctival bacterial pathogen Mycoplasma gallisepticum (MG), to experimentally examine the impact of the ocular microbiome on host damage and pathogen virulence factors during infection. We disrupted the ocular bacterial community of healthy finches using an antibiotic that MG is intrinsically resistant to, then inoculated antibiotic- and sham-treated birds with MG. House finches with antibiotic-disrupted ocular microbiomes had more severe MG-induced conjunctival inflammation than birds with unaltered microbiomes, even after accounting for differences in conjunctival MG load. Furthermore, MG cultures from finches with disrupted microbiomes had increased sialidase enzyme and cytadherence activity, traits associated with enhanced virulence in Mycoplasmas, relative to isolates from sham-treated birds. Variation in sialidase activity and cytadherence among isolates was tightly linked with degree of tissue inflammation in hosts, supporting the consideration of these traits as virulence factors in this system. Overall, our results suggest that microbial dysbiosis can result in enhanced virulence of colonizing pathogens, with critical implications for the health of wildlife, domestic animals, and humans. PMID- 29170423 TI - Bamboo sheath-A modified branch based on the anatomical observations. AB - Culm sheath has always been considered a modified leaf. In this study, the anatomical structure of the culm sheath from Fargesia yunnanensis was analyzed to determine whether it originated from the foliage leaf blade or from the branch. The vascular bundles of the culm sheath showed greater similarity to the branches in shape and anatomical structure. In contrast to foliage blades, there are no midribs in culm sheaths. Stomatal density in the culm sheath is greater in the adaxial than it is in the abaxial epidermis, which is the opposite of that found in foliage leaf blades, and that density shows greater similarity to branches than it does to foliage blades. Fusoid cells are distributed on both sites of the vascular bundles in foliage blades, whereas culm sheaths have, instead, a few parenchyma cells that disintegrate and form air cavities when the sheath matures. Additionally, the culm sheath has no bulliform cells or trichome in its epidermis, and the shape of its long cells shows greater similarity to those of branches. Therefore, culm sheath is a modified branch, rather than a modified leaf. PMID- 29170422 TI - Species composition and environmental adaptation of indigenous Chinese cattle. AB - Indigenous Chinese cattle combine taurine and indicine origins and occupy a broad range of different environments. By 50 K SNP genotyping we found a discontinuous distribution of taurine and indicine cattle ancestries with extremes of less than 10% indicine cattle in the north and more than 90% in the far south and southwest China. Model-based clustering and f4-statistics indicate introgression of both banteng and gayal into southern Chinese cattle while the sporadic yak influence in cattle in or near Tibetan area validate earlier findings of mitochondrial DNA analysis. Geographic patterns of taurine and indicine mitochondrial and Y chromosomal DNA diversity largely agree with the autosomal cline. The geographic distribution of the genomic admixture of different bovine species is proposed to be the combined effect of prehistoric immigrations, gene flow, major rivers acting as genetic barriers, local breeding objectives and environmental adaptation. Whole-genome scan for genetic differentiation and association analyses with both environmental and morphological covariables are remarkably consistent with previous studies and identify a number of genes implicated in adaptation, which include TNFRSF19, RFX4, SP4 and several coat color genes. We propose indigenous Chinese cattle as a unique and informative resource for gene level studies of climate adaptation in mammals. PMID- 29170424 TI - p300-mediated acetylation increased the protein stability of HIPK2 and enhanced its tumor suppressor function. AB - Homeodomain-interacting protein kinase 2 (HIPK2) is a nuclear serine/threonine kinase that functions in development and tumor suppression. One of the prominent features of this kinase is that it is tightly regulated by proteasomal degradation. In the present study, we present evidence suggesting that the protein stability of HIPK2 can be regulated by p300-mediated acetylation. p300 increased the protein level of HIPK2 via its acetyltransferase activity. p300 increased the acetylation of HIPK2 while decreased polyubiquitination and its proteasomal degradation. We also observed that DNA damage induced acetylation of HIPK2 along with an increase in the protein amount, which was inhibited by p300 RNAi. Importantly, p300 promoted p53 activation and the HIPK2-mediated suppression of cell proliferation, suggesting acetylation-induced HIPK2 stabilization contributed to the enhanced activation of HIPK2. Overexpression of p300 promoted the HIPK2-mediated suppression of tumor growth in mouse xenograft model as well. Taken together, our data suggest that p300-mediated acetylation of HIPK2 increases the protein stability of HIPK2 and enhances its tumor suppressor function. PMID- 29170425 TI - TRADD mediates the tumor necrosis factor-induced apoptosis of L929 cells in the absence of RIP3. AB - Receptor-interacting protein kinase 3 (RIP3) is a critical initiator in mediating necroptosis induced by tumor necrosis factor alpha (TNFalpha) in L929 cells, so knockdown of RIP3 inhibits TNFalpha-induced L929 cell necroptosis. However, RIP3 knockdown was shown to switch TNFalpha-induced necroptosis to apoptosis in L929 cells in other studies. Therefore, whether RIP3 knockdown blocks the TNFalpha induced death of L929 cells is controversial. In this study, TNFalpha activated caspase pathway and induced cell death in RIP3 knockdown L929 cells, and the RIP3 independent cell death had been blocked by Z-VAD-FMK (pan-caspase inhibitor) or caspase 8 knockdown, demonstrating that RIP3 knockdown switched TNFalpha-induced necroptosis to caspase-dependent apoptosis. Although both TNF receptor type 1 associated death domain protein (TRADD) and RIP1 have been reported to mediate TNFalpha-induced apoptosis, the knockdown of TRADD, but not RIP1, suppressed TNFalpha-induced activation of the caspase pathway and subsequent apoptosis in RIP3 knockdown L929 cells. In addition, TRADD bound and activated caspase 8 during the RIP3-independent apoptosis process, indicating that TRADD initiates RIP3-independent apoptosis by activating the caspase pathway. Collectively, we identified the target and mechanism underlying RIP3-independent apoptosis and elucidated the coordinated roles of RIP3 and TRADD in mediating the programmed cell death of L929 cells following TNFalpha stimulation. PMID- 29170426 TI - Non-Invasive whole-body detection of complement activation using radionuclide imaging in a mouse model of myocardial ischaemia-reperfusion injury. AB - Complement activation is a recognised mediator of myocardial ischaemia reperfusion-injury (IRI) and cardiomyocytes are a known source of complement proteins including the central component C3, whose activation products can mediate tissue inflammation, cell death and profibrotic signalling. We investigated the potential to detect and quantify the stable covalently bound product C3d by external body imaging, as a marker of complement activation in heart muscle in a murine model of myocardial IRI. We used single-photon-emission computed-tomography (SPECT) in conjunction with 99mTechnecium-labelled recombinant complement receptor 2 (99mTc-rCR2), which specifically detects C3d at the site of complement activation. Compared to control imaging with an inactive CR2 mutant (99mTc-K41E CR2) or an irrelevant protein (99mTc-PSMA) or using 99mTc rCR2 in C3-deficient mice, the use of 99mTc-rCR2 in complement-intact mice gave specific uptake in the reperfused myocardium. The heart to skeletal muscle ratio of 99mTc-rCR2 was significantly higher than in the three control groups. Histological analysis confirmed specific uptake of 99mTc-rCR2. Following therapeutic inhibition of complement C3 activation, we found reduced myocardial uptake of 99mTc-rCR2. We conclude, therefore that 99mTc-rCR2 imaging can be used for non-invasive detection of activated complement and in future could be exploited to quantify the severity of myocardial damage due to complement activation. PMID- 29170427 TI - Genome-wide proteomic profiling reveals the role of dominance protein expression in heterosis in immature maize ears. AB - Heterosis refers to the phenomenon in which hybrid progeny show superior performance relative to their parents. Early maize ear development shows strong heterosis in ear architecture traits and greatly affects grain yield. To explore the underlying molecular mechanisms, genome-wide proteomics of immature ears of maize hybrid ZD909 and its parents were analyzed using tandem mass tag (TMT) technology. A total of 9,713 proteins were identified in all three genotypes. Among them, 3,752 (38.6%) proteins were differentially expressed between ZD909 and its parents. Multiple modes of protein action were discovered in the hybrid, while dominance expression patterns accounted for 63.6% of the total differentially expressed proteins (DEPs). Protein pathway enrichment analysis revealed that high parent dominance proteins mainly participated in carbon metabolism and nitrogen assimilation processes. Our results suggested that the dominant expression of favorable alleles related to C/N metabolism in the hybrid may be essential for ZD909 ear growth and heterosis formation. Integrated analysis of proteomic and quantitative trait locus (QTL) data further support our DEP identification and provide useful information for the discovery of genes associated with ear development. Our study provides comprehensive insight into the molecular mechanisms underlying heterosis in immature maize ears from a proteomic perspective. PMID- 29170428 TI - Complex three-dimensional self-assembly in proxies for atmospheric aerosols. AB - Aerosols are significant to the Earth's climate, with nearly all atmospheric aerosols containing organic compounds that often contain both hydrophilic and hydrophobic parts. However, the nature of how these compounds are arranged within an aerosol droplet remains unknown. Here we demonstrate that fatty acids in proxies for atmospheric aerosols self-assemble into highly ordered three dimensional nanostructures that may have implications for environmentally important processes. Acoustically trapped droplets of oleic acid/sodium oleate mixtures in sodium chloride solution are analysed by simultaneous synchrotron small-angle X-ray scattering and Raman spectroscopy in a controlled gas-phase environment. We demonstrate that the droplets contained crystal-like lyotropic phases including hexagonal and cubic close-packed arrangements of spherical and cylindrical micelles, and stacks of bilayers, whose structures responded to atmospherically relevant humidity changes and chemical reactions. Further experiments show that self-assembly reduces the rate of the reaction of the fatty acid with ozone, and that lyotropic-phase formation also occurs in more complex mixtures more closely resembling compositions of atmospheric aerosols. We suggest that lyotropic-phase formation likely occurs in the atmosphere, with potential implications for radiative forcing, residence times and other aerosol characteristics.

PMID- 29170429 TI - Genome-wide meta-analysis in Japanese populations identifies novel variants at the TMC6-TMC8 and SIX3-SIX2 loci associated with HbA1c. AB - Glycated haemoglobin (HbA1c) is widely used as a biomarker for the diagnosis of diabetes, for population-level screening, and for monitoring the glycaemic status during medical treatment. Although the heritability of HbA1c has been estimated at ~55-75%, a much smaller proportion of phenotypic variance is explained by the HbA1c-associated variants identified so far. To search for novel loci influencing the HbA1c levels, we conducted a genome-wide meta-analysis of 2 non-diabetic Japanese populations (n = 7,704 subjects in total). We identified 2 novel loci that achieved genome-wide significance: TMC6-TMC8 (P = 5.3 * 10-20) and SIX3-SIX2 (P = 8.6 * 10-9). Data from the largest-scale European GWAS conducted for HbA1c supported an association between the novel TMC6-TMC8 locus and HbA1c (P = 2.7 * 10-3). The association analysis with glycated albumin and glycation gap conducted using our Japanese population indicated that the TMC6-TMC8 and SIX3-SIX2 loci may influence the HbA1c level through non-glycaemic and glycaemic pathways, respectively. In addition, the pathway-based analysis suggested that the linoleic acid metabolic and 14-3-3-mediated signalling pathways were associated with HbA1c. These findings provide novel insights into the molecular mechanisms that modulate the HbA1c level in non-diabetic subjects. PMID- 29170431 TI - Relative importance of dietary uptake and waterborne exposure for a leaf shredding amphipod exposed to thiacloprid-contaminated leaves. AB - Systemic neonicotinoids are commonly used in forest pest management programs. Senescent leaves containing neonicotinoids may, however, fall from treated trees into nearby streams. There, leaf-shredding invertebrates are particularly exposed due to their diet (feeding on neonicotinoid-contaminated leaves) or collaterally via the water phase (leaching of a neonicotinoid from leaves) - a fact not considered during aquatic environmental risk assessment. To unravel the relevance of these pathways we used leaves from trees treated with the neonicotinoid thiacloprid to subject the amphipod shredder Gammarus fossarum for 21 days (n = 40) either to dietary, waterborne or a combined (dietary + waterborne) exposure. Dietary exposure caused - relative to the control - similar reductions in gammarids' leaf consumption (~35%) and lipid content (~20%) as observed for the waterborne exposure pathway (30 and 22%). The effect sizes observed under combined exposure suggested additivity of effects being largely predictable using the reference model "independent action". Since gammarids accumulated - independent of the exposure pathway - up to 280 ng thiacloprid/g, dietary exposure may also be relevant for predators which prey on Gammarus. Consequently, neglecting dietary exposure might underestimate the environmental risk systemic insecticides pose for ecosystem integrity calling for its consideration during the evaluation and registration of chemical stressors. PMID- 29170432 TI - Ocular effects of virtual reality headset wear in young adults. AB - Virtual Reality (VR) headsets create immersion by displaying images on screens placed very close to the eyes, which are viewed through high powered lenses. Here we investigate whether this viewing arrangement alters the binocular status of the eyes, and whether it is likely to provide a stimulus for myopia development. We compared binocular status after 40-minute trials in indoor and outdoor environments, in both real and virtual worlds. We also measured the change in thickness of the ocular choroid, to assess the likely presence of signals for ocular growth and myopia development. We found that changes in binocular posture at distance and near, gaze stability, amplitude of accommodation and stereopsis were not different after exposure to each of the 4 environments. Thus, we found no evidence that the VR optical arrangement had an adverse effect on the binocular status of the eyes in the short term. Choroidal thickness did not change after either real world trial, but there was a significant thickening (~10 microns) after each VR trial (p < 0.001). The choroidal thickening which we observed suggest that a VR headset may not be a myopiagenic stimulus, despite the very close viewing distances involved. PMID- 29170433 TI - Lipoprotein-associated phospholipase A2 and oxidized low-density lipoprotein in young patients with acute coronary syndrome in China. AB - Lipoprotein-associated phospholipase A2 (Lp-PLA2) is considered to be a risk factor for acute coronary syndrome (ACS), but this remains controversial. This study investigated the role of Lp-PLA2 in young Chinese patients with ACS. 228 young patients (aged <=55 years) with ACS and 237 age-matched controls were included. Lp-PLA2 and oxidized low-density lipoprotein (ox-LDL) levels were measured by sandwich enzyme-linked immunosorbent assay. Lp-PLA2 levels were significantly correlated with smoking, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and ox-LDL levels (all P < 0.05). Multivariate logistic regression analysis showed that male sex (OR = 3.25, 95%CI = 1.26-8.38), smoking (OR = 3.50, 95%CI = 1.75-7.0), triglyceride (OR = 1.76, 95%CI = 1.08 2.87), high sensitivity C-reactive protein (hs-CRP) (OR = 2.11, 95%CI = 1.14 3.90) and ox-LDL (OR = 2.98, 95%CI = 1.72-5.1) were independently associated with ACS risk in young patients. Lp-PLA2 was associated with risk of ACS in young patients when adjusted for traditional risk factors, including age, sex, diabetes, hypertension, smoking, TC, LDL-C, triglyceride and hs-CRP (OR = 1.98, 95%CI = 1.10-3.56). When further adjusted for ox-LDL levels, the association between Lp-PLA2 and ACS became insignificant (OR = 1.69, 95%CI = 0.90-3.17). Lp PLA2 was a marker of oxidative stress and inflammation, rather than an independent risk factor for ACS in young Chinese patients.

AB - Panonychus citri is one of the most damaging pests of horticultural crops. Conventional control of this pest population through pesticides has led to the enhanced pest resistance. Management of P. citri population through RNAi, is still largely unknown. In oviparous organisms, fabrication and development of yolk protein play a vital role in the reproduction. Vitellin (Vn) is the source of eggs storage that helps in proper functioning of Vitellogenin (Vg) and Vitellogenin receptor (VgR). VgR is very compulsory protein for the development of Vg into oocytes. In the current study, Vg (PcVg) and VgR (PcVgR) genes were studied and their expressions at different developmental stages were quantified by RT-qPCR. Females treated with dsRNA of PcVg and PcVgR genes exhibited reduction in gene expression. Down regulation of target genes significantly effected oviposition and reduced the egg laying capacity up to 48% as compared to control (ds-egfp). Synergistic effect of target gene's dsRNA was also accessed that reduced the egg laying up to 60.42%. Furthermore, combination of target dsRNA on deutonymph and protonymph also resulted in 67% and 70% reduction in eggs, respectively. Synergistic effect of dsRNA at 1000 ng/ul resulted in longer life span as compared to control treatments. This study suggests to develop a new strategy of P. citri population control by reducing its reproduction. PMID- 29170436 TI - Fate tracing of hepatocytes in mouse liver. AB - Hepatocytes perform most of the functions of the liver and are considered terminally differentiated cells. Recently, it has been suggested that hepatocytes might have the potential to transdifferentiate or dedifferentiate under physiological or pathological conditions in vivo. Epithelial-mesenchymal transition of hepatocytes in liver fibrosis has also been proposed. However, these findings have not been fully confirmed. In this study, hepatocytes were genetically labelled for cell fate tracing using lacZ via the tamoxifen-induced CreERT/loxP system. After induction with tamoxifen, alb + cells were permanently marked by lacZ expression, and all progeny lacZ + cells were derived from a single source with no interference. We did not observe transdifferentiation or dedifferentiation of hepatocytes into cholangiocytes or hepatic progenitor cells under conditions of liver homeostasis or following a 2/3 partial hepatectomy. Meanwhile, lacZ/OPN-positive cells were observed in livers of 3,5 diethoxycarbonyl-1,4-dihydrocollidine-fed mice, and lacZ/alpha-smooth muscle actin-positive cells were detected in carbon tetrachloride-induced chronic liver injury models. These results suggested that some existing differentiated alb + cells might have the potential of transdifferentiation/dedifferentiation or epithelial-to-mesenchymal transition in vivo in some liver injury models, but the proportion of these alb + cells in liver was very low, and their significance and actual function during the pathological process remains to be elucidated. PMID- 29170434 TI - Single-cell absolute contact probability detection reveals chromosomes are organized by multiple low-frequency yet specific interactions. AB - At the kilo- to megabase pair scales, eukaryotic genomes are partitioned into self-interacting modules or topologically associated domains (TADs) that associate to form nuclear compartments. Here, we combine high-content super resolution microscopies with state-of-the-art DNA-labeling methods to reveal the variability in the multiscale organization of the Drosophila genome. We find that association frequencies within TADs and between TAD borders are below ~10%, independently of TAD size, epigenetic state, or cell type. Critically, despite this large heterogeneity, we are able to visualize nanometer-sized epigenetic domains at the single-cell level. In addition, absolute contact frequencies within and between TADs are to a large extent defined by genomic distance, higher order chromosome architecture, and epigenetic identity. We propose that TADs and compartments are organized by multiple, small-frequency, yet specific interactions that are regulated by epigenetics and transcriptional state. PMID- 29170437 TI - The responses of cancer cells to PLK1 inhibitors reveal a novel protective role for p53 in maintaining centrosome separation. AB - Polo-like kinase-1 (PLK1) plays a major role in driving mitotic events, including centrosome disjunction and separation, and is frequently over-expressed in human cancers. PLK1 inhibition is a promising therapeutic strategy and works by arresting cells in mitosis due to monopolar spindles. The p53 tumour suppressor protein is a short-lived transcription factor that can inhibit the growth, or stimulate the death, of developing cancer cells. Curiously, although p53 normally acts in an anti-cancer capacity, it can offer significant protection against inhibitors of PLK1, but the events underpinning this effect are not known. Here, we show that functional p53 reduces the sensitivity to PLK1 inhibitors by permitting centrosome separation to occur, allowing cells to traverse mitosis and re-enter cycle with a normal complement of 2N chromosomes. Protection entails the activation of p53 through the DNA damage-response enzymes, ATM and ATR, and requires the phosphorylation of p53 at the key regulatory site, Ser15. These data highlight a previously unrecognised link between p53, PLK1 and centrosome separation that has therapeutic implications for the use of PLK1 inhibitors in the clinic. PMID- 29170438 TI - Solar energy converters based on multi-junction photoemission solar cells. AB - Multi-junction solar cells with multiple p-n junctions made of different semiconductor materials have multiple bandgaps that allow reducing the relaxation energy loss and substantially increase the power-conversion efficiency. The choice of materials for each sub-cell is very limited due to the difficulties in extracting the current between the layers caused by the requirements for lattice- and current-matching. We propose a new vacuum multi-junction solar cell with multiple p-n junctions separated by vacuum gaps that allow using different semiconductor materials as cathode and anode, both activated to the state of effective negative electron affinity (NEA). In this work, the compact proximity focused vacuum tube with the GaAs(Cs,O) photocathode and AlGaAs/GaAs-(Cs,O) anode with GaAs quantum wells (QWs) is used as a prototype of a vacuum single-junction solar cell. The photodiode with the p-AlGaAs/GaAs anode showed the spectral power conversion efficiency of about 1% at V bias = 0 in transmission and reflection modes, while, at V bias = 0.5 V, the efficiency increased up to 10%. In terms of energy conservation, we found the condition at which the energy cathode-to-anode transition was close to 1. Considering only the energy conservation part, the NEA cell power-conversion efficiency can rich a quantum yield value which is measured up to more than 50%. PMID- 29170439 TI - Body representation disturbances in visual perception and affordance perception persist in eating disorder patients after completing treatment. AB - Body image disturbances (BID) are a key feature of eating disorders (ED). Clinical experience shows that BID exists in patients who Completed their Eating Disorder Treatment (CEDT), however studies concerning BID in CEDT patients are often limited to cognition and affect, measured by interviews and questionnaires. The current study is the first systematic study investigating the full scope of the mental body representation, including bodily attitudes, visual perception of body size, tactile perception, and affordance perception in CEDT patients. ED patients (N = 22), CEDT patients (N = 39) and healthy controls (HC; N = 30) were compared on BID tasks including the Body Attitude Test (BAT), Visual Size Estimation (VSE), Tactile Estimation Task (TET), and Hoop Task (HT). Results on the BAT show higher scores for ED patients compared to CEDT patients and HC but no difference between CEDT patients and HC. Both ED and CEDT patients show larger overestimations on the VSE and HT compared to HC, where ED patients show the largest overestimations. No group differences were found on the TET. The results indicate the existence of disturbances in visual perception and affordance perception in CEDT patients. Research focussing on more effective treatments for ED addressing multiple (sensory) modalities is advised. PMID- 29170440 TI - Evidence for unconscious regulation of performance in fatigue. AB - Since fatigue is prevalent in modern societies, it is necessary to clarify the neural mechanisms of fatigue. The regulation of performance through fatigue sensation is one of the mechanisms that decreases performance in fatigue. However, it is unknown whether subjective feeling of fatigue is necessary for the regulation of performance. Here, we examined whether decreased performance occurs without increased fatigue sensation through the experiment which was designed to test if fatigue can be learned unconsciously. Healthy male volunteers performed a fatigue-inducing hand-grip task for 10 min while viewing a target image presented without awareness. On the next day, they viewed a control and the target images presented with awareness and the neural activity caused by viewing the images was measured using magnetoencephalography. Results showed the level of fatigue sensation was not altered but grip-strength was decreased by viewing the target image on the second day. The level of beta band power in Brodmann's area 31 was increased by viewing the target image and this increase was negatively associated with the decrease of grip-strength caused in the hand-grip task. These findings demonstrated that fatigue can be learned unconsciously and that there is a mechanism to decrease performance without fatigue sensation. PMID- 29170441 TI - Genome-wide identification and differential analysis of translational initiation. AB - Translation is principally regulated at the initiation stage. The development of the translation initiation (TI) sequencing (TI-seq) technique has enabled the global mapping of TIs and revealed unanticipated complex translational landscapes in metazoans. Despite the wide adoption of TI-seq, there is no computational tool currently available for analyzing TI-seq data. To fill this gap, we develop a comprehensive toolkit named Ribo-TISH, which allows for detecting and quantitatively comparing TIs across conditions from TI-seq data. Ribo-TISH can also predict novel open reading frames (ORFs) from regular ribosome profiling (rRibo-seq) data and outperform several established methods in both computational efficiency and prediction accuracy. Applied to published TI-seq/rRibo-seq data sets, Ribo-TISH uncovers a novel signature of elevated mitochondrial translation during amino-acid deprivation and predicts novel ORFs in 5'UTRs, long noncoding RNAs, and introns. These successful applications demonstrate the power of Ribo TISH in extracting biological insights from TI-seq/rRibo-seq data. PMID- 29170442 TI - Inhibition of the inflammatory response to stress by targeting interaction between PKR and its cellular activator PACT. AB - PKR is a cellular kinase involved in the regulation of the integrative stress response (ISR) and pro-inflammatory pathways. Two N-terminal dsRNA Binding Domains (DRBD) are required for activation of PKR, by interaction with either dsRNA or PACT, another cellular DRBD-containing protein. A role for PKR and PACT in inflammatory processes linked to neurodegenerative diseases has been proposed and raised interest for pharmacological PKR inhibitors. However, the role of PKR in inflammation is subject to controversy. We identified the flavonoid luteolin as an inhibitor of the PKR/PACT interaction at the level of their DRBDs using high-throughput screening of chemical libraries by homogeneous time-resolved fluorescence. This was further validated using NanoLuc-Based Protein Complementation Assay. Luteolin inhibits PKR phosphorylation, the ISR and the induction of pro-inflammatory cytokines in human THP1 macrophages submitted to oxidative stress and toll-like receptor (TLR) agonist. Similarly, luteolin inhibits induction of pro-inflammatory cytokines in murine microglial macrophages. In contrast, luteolin increased activation of the inflammasome, in a PKR-independent manner. Collectively, these data delineate the importance of PKR in the inflammation process to the ISR and induction of pro-inflammatory cytokines. Pharmacological inhibitors of PKR should be used in combination with drugs targeting directly the inflammasome. PMID- 29170444 TI - Enhanced strength and ductility in a friction stir processing engineered dual phase high entropy alloy. AB - The potential of high-entropy alloys (HEAs) to exhibit an extraordinary combination of properties by shifting the compositional regime from the corners towards the centers of phase diagrams has led to worldwide attention by material scientists. Here we present a strong and ductile non-equiatomic HEA obtained after friction stir processing (FSP). A transformation-induced plasticity (TRIP) assisted HEA with composition Fe50Mn30Co10Cr10 (at.%) was severely deformed by FSP and evaluated for its microstructure-mechanical property relationship. The FSP-engineered microstructure of the TRIP HEA exhibited a substantially smaller grain size, and optimized fractions of face-centered cubic (f.c.c., gamma) and hexagonal close-packed (h.c.p., epsilon) phases, as compared to the as homogenized reference material. This results in synergistic strengthening via TRIP, grain boundary strengthening, and effective strain partitioning between the gamma and epsilon phases during deformation, thus leading to enhanced strength and ductility of the TRIP-assisted dual-phase HEA engineered via FSP. PMID- 29170443 TI - Should we screen for the sexually-transmitted infection Mycoplasma genitalium? Evidence synthesis using a transmission-dynamic model. AB - There is increasing concern about Mycoplasma genitalium as a cause of urethritis, cervicitis, pelvic inflammatory disease (PID), infertility and ectopic pregnancy. Commercial nucleic acid amplification tests (NAATs) are becoming available, and their use in screening for M. genitalium has been advocated, but M. genitalium's natural history is poorly-understood, making screening's effectiveness unclear. We used a transmission-dynamic compartmental model to synthesise evidence from surveillance data and epidemiological and behavioural studies to better understand M. genitalium's natural history, and then examined the effects of implementing NAAT testing. Introducing NAAT testing initially increases diagnoses, by finding a larger proportion of infections; subsequently the diagnosis rate falls, due to reduced incidence. Testing only symptomatic patients finds relatively little infection in women, as a large proportion is asymptomatic. Testing both symptomatic and asymptomatic patients has a much larger impact and reduces cumulative PID incidence in women due to M. genitalium by 31.1% (95% range:13.0%-52.0%) over 20 years. However, there is important uncertainty in M. genitalium's natural history parameters, leading to uncertainty in the absolute reduction in PID and sequelae. Empirical work is required to improve understanding of key aspects of M. genitalium's natural history before it will be possible to determine the effectiveness of screening. PMID- 29170445 TI - A novel bi-domain plant defensin MtDef5 with potent broad-spectrum antifungal activity binds to multiple phospholipids and forms oligomers. AB - Defensins are cysteine-rich cationic antimicrobial peptides contributing to the innate immunity in plants. A unique gene encoding a highly cationic bi-domain defensin MtDef5 has been identified in a model legume Medicago truncatula. MtDef5 consists of two defensin domains of 50 amino acids each linked by a 7-amino acid peptide. It exhibits broad-spectrum antifungal activity against filamentous fungi at submicromolar concentrations. It rapidly permeabilizes the plasma membrane of the ascomycete fungi Fusarium graminearum and Neurospora crassa and induces accumulation of reactive oxygen species. It is internalized by these fungi, but uses spatially distinct modes of entry into these fungi. It co-localizes with cellular membranes, travels to nucleus and becomes dispersed in other subcellular locations. It binds to several membrane-resident phospholipids with preference for phosphatidylinositol monophosphates and forms oligomers. Mutations of the cationic amino acids present in the two gamma-core motifs of this defensin that eliminate oligomerization also knockout its ability to induce membrane permeabilization and fungal growth arrest. MtDef5 is the first bi-domain plant defensin that exhibits potent broad-spectrum antifungal activity, recruits multiple membrane phospholipids and forms oligomers in their presence. These findings raise the possibility that MtDef5 might be useful as a novel antifungal agent in transgenic crops. PMID- 29170446 TI - Radiographic assessment of the skeletons of Dolly and other clones finds no abnormal osteoarthritis. AB - Our recent report detailing the health status of cloned sheep concluded that the animals had aged normally. This is in stark contrast to reports on Dolly (first animal cloned from adult cells) whose diagnoses of osteoarthritis (OA) at 51/2 years of age led to considerable scientific concern and media debate over the possibility of early-onset age-related diseases in cloned animals. Our study included four 8-year old ewes derived from the cell line that gave rise to Dolly, yet none of our aged sheep showed clinical signs of OA, and they had radiographic evidence of only mild or, in one case, moderate OA. Given that the only formal record of OA in Dolly is a brief mention of a single joint in a conference abstract, this led us to question whether the original concerns about Dolly's OA were justified. As none of the original clinical or radiographic records were preserved, we undertook radiographic examination of the skeletons of Dolly and her contemporary clones. We report a prevalence and distribution of radiographic OA similar to that observed in naturally conceived sheep, and our healthy aged cloned sheep. We conclude that the original concerns that cloning had caused early-onset OA in Dolly were unfounded. PMID- 29170447 TI - Monocyte-derived exosomes upon exposure to cigarette smoke condensate alter their characteristics and show protective effect against cytotoxicity and HIV-1 replication. AB - Smoking is known to exacerbate HIV-1 pathogenesis, especially in monocytes, through the oxidative stress pathway. Exosomes are known to alter HIV-1 pathogenesis through inter-cellular communication. However, the role of exosomes in smoking-mediated HIV-1 pathogenesis is unknown. In this study, we investigated the effect of cigarette smoke condensate (CSC) on the characteristics of monocyte derived exosomes and their influence on HIV-1 replication. Initially, we demonstrated that CSC reduced total protein and antioxidant capacity in exosomes derived from HIV-1-infected and uninfected macrophages. The exosomes from CSC treated uninfected cells showed a protective effect against cytotoxicity and viral replication in HIV-1-infected macrophages. However, exosomes derived from HIV-1-infected cells lost their protective capacity. The results suggest that the exosomal defense is likely to be more effective during the early phase of HIV-1 infection and diminishes at the latter phase. Furthermore, we showed CSC-mediated upregulation of catalase in exosomes from uninfected cells, with a decrease in the levels of catalase and PRDX6 in exosomes derived from HIV-1-infected cells. These results suggest a potential role of antioxidant enzymes, which are differentially packaged into CSC-exposed HIV-1-infected and uninfected cell derived exosomes, on HIV-1 replication of recipient cells. Overall, our study suggests a novel role of exosomes in tobacco-mediated HIV-1 pathogenesis. PMID- 29170448 TI - Colorectal cancer screening in patients with spinal cord injury yields similar results to the general population with an effective bowel preparation: a retrospective chart audit. AB - STUDY DESIGN: Retrospective chart audit. OBJECTIVES: To compare adequacy of colonoscopy bowel preparation and diagnostic findings between persons with SCI receiving an extended inpatient bowel preparation and the general population. SETTING: Veterans Affairs Puget Sound Healthcare System, Seattle, WA, USA. METHODS: We reviewed an electronic database of all colonoscopies performed at a tertiary Veterans Affairs medical center between 7/12/13 and 15/10/15. Patients with SCI received a multi-day bowel preparation with magnesium citrate, and 8-10 liters of polyethylene glycol-3350 and electrolyte colonic lavage solution (PEG ELS) over two and one half days. The control population received a standard bowel preparation consisting of magnesium citrate and 4 liters of PEG-ELS over 1 day. RESULTS: Two hundred and fifty-five patients were included in the study, including 85 patients with SCI. Average risk screening was a more common colonoscopy indication in patients with SCI vs. the control population (24 vs. 13% p = 0.03). There was no difference in adequacy of bowel preparation (87 vs. 85%, p = 0.73) or adenoma detection rate (55 vs. 51%, p = 0.59) when comparing patients with SCI with the control population. No difference in polyp histopathology was detected (p = 0.748). CONCLUSIONS: Our study demonstrated that an extended bowel preparation for patients with SCI produces similar bowel preparation results and diagnostic yield when compared to patients without SCI undergoing colonoscopy. PMID- 29170449 TI - Quantitative analysis of biofluid spots by coated blade spray mass spectrometry, a new approach to rapid screening. AB - This study demonstrates the quantitative capabilities of coated blade spray (CBS) mass spectrometry (MS) for the concomitant analysis of multiple target substances in biofluid spots. In CBS-MS the analytes present in a given sample are first isolated and enriched in the thin coating of the CBS device. After a quick rinsing of the blade surface, as to remove remaining matrix, the analytes are quickly desorbed with the help of a solvent and then directly electrosprayed into the MS analyzer. Diverse pain management drugs, controlled substances, and therapeutic medications were successfully determined using only 10 uL of biofluid, with limits of quantitation in the low/sub ng.mL-1 level attained within 7 minutes. PMID- 29170451 TI - Chemokines protect vascular smooth muscle cells from cell death induced by cyclic mechanical stretch. AB - The pulsatile nature of blood flow exposes vascular smooth muscle cells (VSMCs) in the vessel wall to cyclic mechanical stretch (CMS), which evokes VSMC proliferation, cell death, phenotypic switching, and migration, leading to vascular remodeling. These responses have been observed in many cardiovascular diseases; however, the underlying mechanisms remain unclear. We have revealed that CMS of rat aortic smooth muscle cells (RASMCs) causes JNK- and p38-dependent cell death and that a calcium channel blocker and angiotensin II receptor antagonist decreased the phosphorylation of JNK and p38 and subsequently decreased cell death by CMS. In the present study, we showed that the expression of Cxcl1 and Cx3cl1 was induced by CMS in a JNK-dependent manner. The expression of Cxcl1 was also induced in VSMCs by hypertension produced by abdominal aortic constriction (AAC). In addition, antagonists against the receptors for CXCL1 and CX3CL1 increased cell death, indicating that CXCL1 and CX3CL1 protect RASMCs from CMS-induced cell death. We also revealed that STAT1 is activated in RASMCs subjected to CMS. Taken together, these results indicate that CMS of VSMCs induces inflammation-related gene expression, including that of CXCL1 and CX3CL1, which may play important roles in the stress response against CMS caused by hypertension. PMID- 29170450 TI - Interplay between Notch1 and Notch3 promotes EMT and tumor initiation in squamous cell carcinoma. AB - Notch1 transactivates Notch3 to drive terminal differentiation in stratified squamous epithelia. Notch1 and other Notch receptor paralogs cooperate to act as a tumor suppressor in squamous cell carcinomas (SCCs). However, Notch1 can be stochastically activated to promote carcinogenesis in murine models of SCC. Activated form of Notch1 promotes xenograft tumor growth when expressed ectopically. Here, we demonstrate that Notch1 activation and epithelial mesenchymal transition (EMT) are coupled to promote SCC tumor initiation in concert with transforming growth factor (TGF)-beta present in the tumor microenvironment. We find that TGFbeta activates the transcription factor ZEB1 to repress Notch3, thereby limiting terminal differentiation. Concurrently, TGFbeta drives Notch1-mediated EMT to generate tumor initiating cells characterized by high CD44 expression. Moreover, Notch1 is activated in a small subset of SCC cells at the invasive tumor front and predicts for poor prognosis of esophageal SCC, shedding light upon the tumor promoting oncogenic aspect of Notch1 in SCC. PMID- 29170453 TI - Association of protein kinase CK2 inhibition with cellular radiosensitivity of non-small cell lung cancer. AB - Protein kinase CK2 is a highly conserved protein Ser/Thr protein kinase and plays important roles in cell proliferation, protein translation and cell survival. This study investigated the possibility of using CK2 inhibition as a new approach for increasing the efficacy of radiotherapy in non-small cell lung cancer (NSCLC) and its underlying mechanisms. Kinase inhibition of CK2 was attempted either by using the specific CK2 inhibitor, Quinalizarin or by applying siRNA interference technology to silence the expression of the catalytic subunit of CK2 in A549 and H460 cells. The results showed that CK2alpha knockdown or Quinalizarin significantly enhanced the radiosensitivity of various NSCLC cells. The notable findings we observed after exposure to both CK2 inhibition and ionizing radiation (IR) were a prolonged delay in radiation-induced DNA double-strand breaks (DSB) repair, robust G2/M checkpoint arrest and increased apoptosis. In vivo studies further demonstrated that compared with each treatment alone, CK2 inhibition combined with IR reduced tumor growth in the H460 cell xenograft model. In conclusion, CK2 is a promising target for the enhancement of radiosensitivity in NSCLC. PMID- 29170452 TI - Liraglutide restores chronic ER stress, autophagy impairments and apoptotic signalling in SH-SY5Y cells. AB - Growing evidence suggests that agonists of glucagon-like peptide (GLP-1) receptor exert neuroprotective and neurorestorative effects across a range of experimental models of neuronal degeneration, and, recently, a pilot clinical trial of Liraglutide in Alzheimer's disease patients showed improvements in cerebral glucose consumption that signifies disease progression. However, the exact underlying mechanism of action remains unclear. Chronic endoplasmic reticulum (ER) stress has recently emerged as a mechanism for neuronal injury, rendering it a potent therapeutic target for acute and chronic neurodegenerative disorders. Here, we investigate the neuroprotective effects of Liraglutide along with the signalling network against prolong ER stress and autophagy impairments induced by the non-competitive inhibitor of sarco/ER Ca2+-ATPase, thapsigargin. We show that Liraglutide modulates the ER stress response and elicits ER proteostasis and autophagy machinery homeostasis in human SH-SY5Y neuroblastoma cell line. These effects correlate with resolution of hyper-activity of the antioxidant Nrf2 factor and restoration of the impaired cell viability and proliferation. Mechanistically, Liraglutide engages Akt and signal transducer and activator of transcription 3 (STAT3) signalling to favour adaptive responses and shift cell fate from apoptosis to survival under chronic stress conditions in SH-SY5Y cells. PMID- 29170454 TI - CB2 receptor activation causes an ERK1/2-dependent inflammatory response in human RPE cells. AB - A chronic low-level inflammation contributes to the pathogenesis of age-related macular degeneration (AMD), the most common cause of blindness in the elderly in Western countries. The loss of central vision results from attenuated maintenance of photoreceptors due to the degeneration of retinal pigment epithelium (RPE) cells beneath the photoreceptor layer. It has been proposed that pathologic inflammation initiated in RPE cells could be regulated by the activation of type 2 cannabinoid receptors (CB2). Here, we have analysed the effect of CB2 activation on cellular survival and inflammation in human RPE cells. RPE cells were treated with the selective CB2 agonist JWH-133 in the presence or absence of the oxidative stressor 4-hydroxynonenal. Thereafter, cellular viability as well as the release of pro-inflammatory cytokines and potential underlying signalling pathways were analysed. Our results show that JWH-133 led to increased intracellular Ca2+ levels, suggesting that RPE cells are capable of responding to a CB2 agonist. JWH-133 could not prevent oxidative stress-induced cell death. Instead, 10 uM JWH-133 increased cell death and the release of proinflammatory cytokines in an ERK1/2-dependent manner. In contrast to previous findings, CB2 activation increased, rather than reduced inflammation in RPE cells. PMID- 29170455 TI - Ultrafast bridge planarization in donor-pi-acceptor copolymers drives intramolecular charge transfer. AB - Donor-pi-acceptor conjugated polymers form the material basis for high power conversion efficiencies in organic solar cells. Large dipole moment change upon photoexcitation via intramolecular charge transfer in donor-pi-acceptor backbone is conjectured to facilitate efficient charge-carrier generation. However, the primary structural changes that drive ultrafast charge transfer step have remained elusive thereby limiting a rational structure-function correlation for such copolymers. Here we use structure-sensitive femtosecond stimulated Raman spectroscopy to demonstrate that pi-bridge torsion forms the primary reaction coordinate for intramolecular charge transfer in donor-pi-acceptor copolymers. Resonance-selective Raman snapshots of exciton relaxation reveal rich vibrational dynamics of the bridge modes associated with backbone planarization within 400 fs, leading to hot intramolecular charge transfer state formation while subsequent cooling dynamics of backbone-centric modes probe the charge transfer relaxation. Our work establishes a phenomenological gating role of bridge torsions in determining the fundamental timescale and energy of photogenerated carriers, and therefore opens up dynamics-based guidelines for fabricating energy efficient organic photovoltaics. PMID- 29170456 TI - Determination of Asphaltene Critical Nanoaggregate Concentration Region Using Ultrasound Velocity Measurements. AB - Asphaltenes constitute the heaviest, most polar and aromatic fraction of petroleum crucial to the formation of highly-stable water-in-crude oil emulsions. The latter occur during crude oil production as well as spills and cause difficulties to efficient remediation practice. It is thought that in nanoaggregate form, asphaltenes create elastic layers around water droplets enhancing stability of the emulsion matrix. Ultrasonic characterisation is a high resolution non-invasive tool in colloidal analysis shown to successfully identify asphaltene nanoaggregation in toluene. The high sensitivity of acoustic velocity to molecular rearrangements and ease in implementation renders it an attractive method to study asphaltene phase properties. Currently, aggregation is thought to correspond to an intersection of two concentration-ultrasonic velocity regressions. Our measurements indicate a variation in the proximity of nanoaggregation which is not accounted for by present models. We attribute this uncertainty to physico-chemical heterogeneity of the asphaltene fraction driven by variation in molecular size and propose a critical nanoaggregation region. We treated asphaltenes from North and South American crude oils with ruthenium ion catalysed oxidation to characterize their n-alkyl appendages attached to aromatic cores. Principal component analysis was performed to investigate the coupling between asphaltene structures and velocity measurements and their impact on aggregation. PMID- 29170457 TI - Pulsed Corona Discharge Induced Hydroxyl Radical Transfer Through the Gas-Liquid Interface. AB - The highly energetic electrons in non-thermal plasma generated by gas phase pulsed corona discharge (PCD) produce hydroxyl (OH) radicals via collision reactions with water molecules. Previous work has established that OH radicals are formed at the plasma-liquid interface, making it an important location for the oxidation of aqueous pollutants. Here, by contacting water as aerosol with PCD plasma, it is shown that OH radicals are produced on the gas side of the interface, and not in the liquid phase. It is also demonstrated that the gas liquid interfacial boundary poses a barrier for the OH radicals, one they need to cross for reactive affinity with dissolved components, and that this process requires a gaseous atomic H scavenger. For gaseous oxidation, a scavenger, oxygen in common cases, is an advantage but not a requirement. OH radical efficiency in liquid phase reactions is strongly temperature dependent as radical termination reaction rates increase with temperature. PMID- 29170458 TI - Towards personalised allele-specific CRISPR gene editing to treat autosomal dominant disorders. AB - CRISPR/Cas9 holds immense potential to treat a range of genetic disorders. Allele specific gene disruption induced by non-homologous end-joining (NHEJ) DNA repair offers a potential treatment option for autosomal dominant disease. Here, we successfully delivered a plasmid encoding S. pyogenes Cas9 and sgRNA to the corneal epithelium by intrastromal injection and acheived long-term knockdown of a corneal epithelial reporter gene, demonstrating gene disruption via NHEJ in vivo. In addition, we used TGFBI corneal dystrophies as a model of autosomal dominant disease to assess the use of CRISPR/Cas9 in two allele-specific systems, comparing cleavage using a SNP-derived PAM to a guide specific approach. In vitro, cleavage via a SNP-derived PAM was found to confer stringent allele specific cleavage, while a guide-specific approach lacked the ability to distinguish between the wild-type and mutant alleles. The failings of the guide specific approach highlights the necessity for meticulous guide design and assessment, as various degrees of allele-specificity are achieved depending on the guide sequence employed. A major concern for the use of CRISPR/Cas9 is its tendency to cleave DNA non-specifically at "off-target" sites. Confirmation that S. pyogenes Cas9 lacks the specificity to discriminate between alleles differing by a single base-pair regardless of the position in the guide is demonstrated. PMID- 29170459 TI - Randomness-induced quantum spin liquid on honeycomb lattice. AB - Quantum entanglement in magnetic materials is expected to yield a quantum spin liquid (QSL), in which strong quantum fluctuations prevent magnetic ordering even at zero temperature. This topic has been one of the primary focuses of condensed matter science since Anderson first proposed the resonating valence bond state in a certain spin-1/2 frustrated magnet in 1973. Since then, several candidate materials featuring frustration, such as triangular and kagome lattices, have been reported to exhibit liquid-like behavior. However, the mechanisms that stabilize the liquid-like states have remained elusive. Here, we present a QSL state in a spin-1/2 honeycomb lattice with randomness in the exchange interaction. That is, we successfully introduce randomness into the organic radial-based complex and realize a random-singlet (RS) state (or valence bond glass). All magnetic and thermodynamic experimental results indicate the liquid like behaviors, which are consistent with those expected in the RS state. Our results suggest that the randomness or inhomogeneity in the actual systems stabilize the RS state and yield liquid-like behavior.

AB - Two genera of terrestrial slugs (Arion and Geomalacus) display a striking disproportion in species richness in the Iberian Peninsula. While there are 17 Iberian endemic species in Arion, morphological criteria only recognize four species within Geomalacus. Sequence data were used to test whether these differences could result from: (1) cryptic diversity within Geomalacus; (2) an earlier origin for Arion (older clades are expected to accumulate more species); (3) distinct patterns of diversification rates (higher initial speciation rates in Arion), and (4) some combination of the above factors (e.g., an older clade with higher speciation rates). Species delimitation tests based on mitochondrial and nuclear data revealed eight cryptic lineages within Geomalacus that lessened the asymmetry; nevertheless, the disparity required further investigation. No meaningful differences in crown group ages of each recovered clade were found. Regardless the different premises of the two equally plausible diversification models (similar initial speciation rates vs. higher initial speciation rates in Geomalacus), both coincide on diversity-dependent diversification for the two groups but weaker rate declines in Arion best explains the observed asymmetry in species richness. Also, the broader environmental tolerance combined with a faster dispersal and wider distribution may have represented an evolutionary advantage for Arion.

The efficiency of observational learning depends on how observational information is used, something we propose depends on our beliefs' about others. Here, we investigated how described and actual abilities of another individual (a demonstrator) influenced performance and psychophysiology during learning of an observational avoidance task. Participants were divided into two groups. In each group there were two demonstrators who were described as either high (Described-High group) or low (Described-Low group) in their ability to learn the task. In both groups, one demonstrator had a high ability (Actual-High) and the other had a low ability (Actual-Low) to learn. Participants performed worse in the Described-Low compared to the Described-High group. Pupil dilation, and behavioral data in combination with reinforcement learning modeling, suggested that the described ability influenced performance by affecting the level of attention towards the observational information. Skin conductance responses and pupil dilation provided us with a separate measure of learning in addition to choice behavior. PMID- 29170463 TI - Associating a product with a luxury brand label modulates neural reward processing and favors choices in materialistic individuals. AB - The present study investigated the extent to which luxury vs. non-luxury brand labels (i.e., extrinsic cues) randomly assigned to items and preferences for these items impact choice, and how this impact may be moderated by materialistic tendencies (i.e., individual characteristics). The main objective was to investigate the neural correlates of abovementioned effects using functional magnetic resonance imaging. Behavioural results showed that the more materialistic people are, the more they choose and like items labelled with luxury brands. Neuroimaging results revealed the implication of a neural network including the dorsolateral and ventromedial prefrontal cortex and the orbitofrontal cortex that was modulated by the brand label and also by the participants' preference. Most importantly, items with randomly assigned luxurious brand labels were preferentially chosen by participants and triggered enhanced signal in the caudate nucleus. This effect increased linearly with materialistic tendencies. Our results highlight the impact of brand-item association, although random in our study, and materialism on preference, relying on subparts of the brain valuation system for the integration of extrinsic cues, preferences and individual characteristics. PMID- 29170464 TI - Giant Anisotropic Magnetocaloric Effect in Double-perovskite Gd2CoMnO6 Single Crystals. AB - The magnetocaloric effect (MCE) is described by the change in temperature of a material by magnetic field variation and is a crucial subject in magnetism; it is motivated by the desire to enhance energy-efficient magnetic refrigeration for clean technology. Despite the recent discovery of the giant cryogenic MCE in double perovskites, the role of magnetic anisotropy has not yet been clearly discussed, because of the averaging effect of polycrystalline samples. Here, we investigated the anisotropic MCE in the single-crystal double perovskite Gd2CoMnO6. In addition to the ferromagnetic order of the Co2+ and Mn4+ moments, the large Gd3+ moments align below T Gd = 21 K, exhibiting an isotropic nature. Because of the intricate temperature development of magnetically hysteretic behaviour and metamagnetism, the change in magnetic entropy along the c-axis appears to be relatively small. On the contrary, the smaller but almost reversible magnetization perpendicular to the c-axis leads to a large MCE with a maximum entropy change of 25.4 J/kg.K. The anisotropic MCE generates a giant rotational MCE, estimated as 16.6 J/kg.K. Our results demonstrate the importance of magnetic anisotropy for understanding the MCE and reveal essential clues for exploring suitable magnetic refrigerant compounds aiming at magnetic functional applications. PMID- 29170462 TI - Structure of Rap1b bound to talin reveals a pathway for triggering integrin activation. AB - Activation of transmembrane receptor integrin by talin is essential for inducing cell adhesion. However, the pathway that recruits talin to the membrane, which critically controls talin's action, remains elusive. Membrane-anchored mammalian small GTPase Rap1 is known to bind talin-F0 domain but the binding was shown to be weak and thus hardly studied. Here we show structurally that talin-F0 binds to human Rap1b like canonical Rap1 effectors despite little sequence homology, and disruption of the binding strongly impairs integrin activation, cell adhesion, and cell spreading. Furthermore, while being weak in conventional binary binding conditions, the Rap1b/talin interaction becomes strong upon attachment of activated Rap1b to vesicular membranes that mimic the agonist-induced microenvironment. These data identify a crucial Rap1-mediated membrane-targeting mechanism for talin to activate integrin. They further broadly caution the analyses of weak protein-protein interactions that may be pivotal for function but neglected in the absence of specific cellular microenvironments. PMID- 29170465 TI - Egr1 deficiency induces browning of inguinal subcutaneous white adipose tissue in mice. AB - Beige adipocyte differentiation within white adipose tissue, referred to as browning, is seen as a possible mechanism for increasing energy expenditure. The molecular regulation underlying the thermogenic browning process has not been entirely elucidated. Here, we identify the zinc finger transcription factor EGR1 as a negative regulator of the beige fat program. Loss of Egr1 in mice promotes browning in the absence of external stimulation and leads to an increase of Ucp1 expression, which encodes the key thermogenic mitochondrial uncoupling protein-1. Moreover, EGR1 is recruited to the proximal region of the Ucp1 promoter in subcutaneous inguinal white adipose tissue. Transcriptomic analysis of subcutaneous inguinal white adipose tissue in the absence of Egr1 identifies the molecular signature of white adipocyte browning downstream of Egr1 deletion and highlights a concomitant increase of beige differentiation marker and a decrease in extracellular matrix gene expression. Conversely, Egr1 overexpression in mesenchymal stem cells decreases beige adipocyte differentiation, while increasing extracellular matrix production. These results reveal a role for Egr1 in blocking energy expenditure via direct Ucp1 transcription repression and highlight Egr1 as a therapeutic target for counteracting obesity. PMID- 29170466 TI - Statistics and simulation of growth of single bacterial cells: illustrations with B. subtilis and E. coli. AB - The inherent stochasticity of molecular reactions prevents us from predicting the exact state of single-cells in a population. However, when a population grows at steady-state, the probability to observe a cell with particular combinations of properties is fixed. Here we validate and exploit existing theory on the statistics of single-cell growth in order to predict the probability of phenotypic characteristics such as cell-cycle times, volumes, accuracy of division and cell-age distributions, using real-time imaging data for Bacillus subtilis and Escherichia coli. Our results show that single-cell growth statistics can accurately be predicted from a few basic measurements. These equations relate different phenotypic characteristics, and can therefore be used in consistency tests of experimental single-cell growth data and prediction of single-cell statistics. We also exploit these statistical relations in the development of a fast stochastic-simulation algorithm of single-cell growth and protein expression. This algorithm greatly reduces computational burden, by recovering the statistics of growing cell-populations from the simulation of only one of its lineages. Our approach is validated by comparison of simulations and experimental data. This work illustrates a methodology for the prediction, analysis and tests of consistency of single-cell growth and protein expression data from a few basic statistical principles. PMID- 29170467 TI - mTORC1 suppresses PIM3 expression via miR-33 encoded by the SREBP loci. AB - The mechanistic target of rapamycin complex 1 (mTORC1) is a central regulator of cell growth that is often aberrantly activated in cancer. However, mTORC1 inhibitors, such as rapamycin, have limited effectiveness as single agent cancer therapies, with feedback mechanisms inherent to the signaling network thought to diminish the anti-tumor effects of mTORC1 inhibition. Here, we identify the protein kinase and proto-oncogene PIM3 as being repressed downstream of mTORC1 signaling. PIM3 expression is suppressed in cells with loss of the tuberous sclerosis complex (TSC) tumor suppressors, which exhibit growth factor independent activation of mTORC1, and in the mouse liver upon feeding-induced activation of mTORC1. Inhibition of mTORC1 with rapamycin induces PIM3 transcript and protein levels in a variety of settings. Suppression of PIM3 involves the sterol regulatory element-binding (SREBP) transcription factors SREBP1 and 2, whose activation and mRNA expression are stimulated by mTORC1 signaling. We find that PIM3 repression is mediated by miR-33, an intronic microRNA encoded within the SREBP loci, the expression of which is decreased with rapamycin. These results demonstrate that PIM3 is induced upon mTORC1 inhibition, with potential implications for the effects of mTORC1 inhibitors in TSC, cancers, and the many other disease settings influenced by aberrant mTORC1 signaling. PMID- 29170468 TI - Non-Invasive Placental Perfusion Imaging in Pregnancies Complicated by Fetal Heart Disease Using Velocity-Selective Arterial Spin Labeled MRI. AB - The placenta is a vital organ for fetal growth and development during pregnancy. Congenital heart disease (CHD) is a leading cause of morbidity and mortality in newborns. Despite the parallel development of the placenta and fetal heart early in pregnancy, very few studies suggested an association between placental dysfunction and fetal CHD. In this study, we report placental perfusion of healthy pregnancies and pregnancies complicated by fetal CHD measured using advanced fetal MRI techniques. We studied forty-eight pregnant women (31 healthy volunteers and 17 with fetal CHD) that underwent fetal MRI during their second or third trimester of pregnancy. Placental perfusion imaging was performed using velocity-selective arterial spin labeling (VSASL) and 3D image acquisition with whole-placenta coverage. In pregnancies with fetal CHD, global placental perfusion significantly decreased and regional variation of placental perfusion significantly increased with advancing gestational age; however, no such correlation was found in healthy pregnancies. Also, global placental perfusion was significantly higher in fetal CHD versus controls, in the lateral side-lying patient position versus supine, and in the posterior placental position versus anterior placental position. This study reports for the first time non-invasive whole-placenta perfusion imaging in utero. These data suggest that placental VSASL may serve as a potential biomarker of placental dysfunction in fetuses diagnosed with CHD. PMID- 29170470 TI - Switchable photovoltaic windows enabled by reversible photothermal complex dissociation from methylammonium lead iodide. AB - Materials with switchable absorption properties have been widely used for smart window applications to reduce energy consumption and enhance occupant comfort in buildings. In this work, we combine the benefits of smart windows with energy conversion by producing a photovoltaic device with a switchable absorber layer that dynamically responds to sunlight. Upon illumination, photothermal heating switches the absorber layer-composed of a metal halide perovskite-methylamine complex-from a transparent state (68% visible transmittance) to an absorbing, photovoltaic colored state (less than 3% visible transmittance) due to dissociation of methylamine. After cooling, the methylamine complex is re-formed, returning the absorber layer to the transparent state in which the device acts as a window to visible light. The thermodynamics of switching and performance of the device are described. This work validates a photovoltaic window technology that circumvents the fundamental tradeoff between efficient solar conversion and high visible light transmittance that limits conventional semitransparent PV window designs. PMID- 29170469 TI - Rapid changes in Atlantic grey seal milk from birth to weaning - immune factors and indicators of metabolic strain. AB - True seals have the shortest lactation periods of any group of placental mammal. Most are capital breeders that undergo short, intense lactations, during which they fast while transferring substantial proportions of their body reserves to their pups, which they then abruptly wean. Milk was collected from Atlantic grey seals (Halichoerus grypus) periodically from birth until near weaning. Milk protein profiles matured within 24 hours or less, indicating the most rapid transition from colostrum to mature phase lactation yet observed. There was an unexpected persistence of immunoglobulin G almost until weaning, potentially indicating prolonged trans-intestinal transfer of IgG. Among components of innate immune protection were found fucosyllactose and siallylactose that are thought to impede colonisation by pathogens and encourage an appropriate milk-digestive and protective gut microbiome. These oligosaccharides decreased from early lactation to almost undetectable levels by weaning. Taurine levels were initially high, then fell, possibly indicative of taurine dependency in seals, and progressive depletion of maternal reserves. Metabolites that signal changes in the mother's metabolism of fats, such as nicotinamide and derivatives, rose from virtual absence, and acetylcarnitines fell. It is therefore possible that indicators of maternal metabolic strain exist that signal the imminence of weaning. PMID- 29170471 TI - Steps forward for cancer precision medicine. AB - The availability of targeted anticancer drugs and the relative affordability of genomic analyses has led to a growing expectation among patients with cancer that they can receive personalized treatment based on the genomic signature of their tumour. Here, we discuss some of the challenges and steps needed to bring such approaches into routine practice. PMID- 29170472 TI - Interaction Effects of AFB1 and MC-LR Co-exposure with Polymorphism of Metabolic Genes on Liver Damage: focusing on SLCO1B1 and GSTP1. AB - AFB1 and MC-LR are two major environmental risk factors for liver damage worldwide, especially in warm and humid areas, but there are individual differences in health response of the toxin-exposed populations. Therefore, we intended to identify the susceptible genes in transport and metabolic process of AFB1 and MC-LR and find their effects on liver damage. We selected eight related SNPs that may affect liver damage outcomes in AFB1 and MC-LR exposed persons, and enrolled 475 cases with liver damage and 475 controls of healthy people in rural areas of China. The eight SNPs were genotyped by PCR and restriction fragment length polymorphism. We found that SLCO1B1 (T521C) is a risk factor for liver damage among people exposed to high AFB1 levels alone or combined with MC-LR, and that GSTP1 (A1578G) could indicate the risk of liver damage among those exposed to high MC-LR levels alone or combined with high AFB1 levels. However, GSTP1 (A1578G) could reduce the risk of liver damage in populations exposed to low MC LR levels alone or combined with high AFB1 levels. In conclusion, SLCO1B1 (T521C) and GSTP1 (A1578G) are susceptible genes for liver damage in humans exposed to AFB1 and/or MC-LR in rural areas of China. PMID- 29170473 TI - Generation of an osteoblast-based artificial niche that supports in vitro B lymphopoiesis. AB - B lymphocytes are produced from hematopoietic stem cells (HSCs) through the highly ordered process of B lymphopoiesis, which is regulated by a complex network of cytokines, chemokines and cell adhesion molecules derived from the hematopoietic niche. Primary osteoblasts function as an osteoblastic niche (OBN) that supports in vitro B lymphopoiesis. However, there are significant limitations to the use of primary osteoblasts, including their relative scarcity and the consistency and efficiency of the limited purification and proliferation of these cells. Thus, development of a stable osteoblast cell line that can function as a biomimetic or artificial OBN is necessary. In this study, we developed a stable osteoblastic cell line, designated OBN4, which functions as an osteoblast-based artificial niche that supports in vitro B lymphopoiesis. We demonstrated that the production of a B220+ cell population from Lineage- (Lin-) Sca-1+ c-Kit+ hematopoietic stem and progenitor cells (HSPCs) was increased ~1.7 fold by OBN4 cells relative to production by primary osteoblasts and OP9 cells in coculture experiments. Consistently, OBN4 cells exhibited the highest production of B220+ IgM+ cell populations (6.7+/-0.6-13.6+/-0.6%) in an IL-7- and stromal cell-derived factor 1-dependent manner, with higher production than primary osteoblasts (3.7+/-0.5-6.4+/-0.6%) and OP9 cells (1.8+/-0.6-3.9+/-0.5%). In addition, the production of B220+ IgM+ IgD+ cell populations was significantly enhanced by OBN4 cells (15.4+/-1.1-18.9+/-3.2%) relative to production by primary osteoblasts (9.5+/-0.6-14.6+/-1.6%) and OP9 cells (9.1+/-0.5-10.3+/-1.8%). We conclude that OBN4 cells support in vitro B lymphopoiesis of Lin- Sca-1+ c-Kit+ HSPCs more efficiently than primary osteoblasts or OP9 stromal cells. PMID- 29170475 TI - Leukotriene B4 receptor 2 gene polymorphism (rs1950504, Asp196Gly) leads to enhanced cell motility under low-dose ligand stimulation. AB - Recently, single-nucleotide polymorphisms (SNPs) in G-protein-coupled receptors (GPCRs) have been suggested to contribute to physiopathology and therapeutic effects. Leukotriene B4 receptor 2 (BLT2), a member of the GPCR family, plays a critical role in the pathogenesis of several inflammatory diseases, including cancer and asthma. However, no studies on BLT2 SNP effects have been reported to date. In this study, we demonstrate that the BLT2 SNP (rs1950504, Asp196Gly), a Gly-196 variant of BLT2 (BLT2 D196G), causes enhanced cell motility under low dose stimulation of its ligands. In addition, we demonstrated that Akt activation and subsequent production of reactive oxygen species (ROS), both of which act downstream of BLT2, are also increased by BLT2 D196G in response to low-dose ligand stimulation. Furthermore, we observed that the ligand binding affinity of BLT2 D196G was enhanced compared with that of BLT2. Through homology modeling analysis, it was predicted that BLT2 D196G loses ionic interaction with R197, potentially resulting in increased agonist-receptor interaction. To the best of our knowledge, this report is the first to describe a SNP study on BLT2 and shows that BLT2 D196G enhances ligand sensitivity, thereby increasing cell motility in response to low-dose ligand stimulation.

AB - Urea breath test (UBT), as a leading preferred non-invasive diagnostic technology, but may not be able to detect oral H. pylori. With negative results of UBT, the patient may have an oral infection. On the basis of the fact of success, eradication rate may increase by 21% in the 95% Cl range after the elimination of oral H. pylori, the author believes oral H. pylori does exist and the oral cavity is the second colonized site aside its primary site of the stomach. H. pylori migrated out of Africa along with its human host circa 60 000 years ago; they are not lives in stomach only. In this review article, evidence established in recent years studies with use more appropriate technology had been listed and discussed. The author considers the oral cavity is a black hole for H. pylori infection that significant effective on gastroenterology and another medical field. The role of the oral cavity as the source of H. pylori infection is so controvert in past years. It seems like a human being having a second-time face to discover H. pylori in the history. PMID- 29170476 TI - Trib2 regulates the pluripotency of embryonic stem cells and enhances reprogramming efficiency. AB - Embryonic stem (ES) cells are pluripotent cells characterized by self renewability and differentiation potential. Induced pluripotent stem (iPS) cells are ES cell-equivalent cells derived from somatic cells by the introduction of core reprogramming factors. ES and iPS cells are important sources for understanding basic biology and for generating therapeutic cells for clinical applications. Tribbles homolog 2 (Trib2) functions as a scaffold in signaling pathways. However, the relevance of Trib2 to the pluripotency of ES and iPS cells is unknown. In the present study, we elucidated the importance of Trib2 in maintaining pluripotency in mouse ES cells and in generating iPS cells from somatic cells through the reprogramming process. Trib2 expression decreased as ES cells differentiated, and Trib2 knockdown in ES cells changed their colony morphology while reducing the activity of alkaline phosphatase and the expression of the pluripotency marker genes Oct4, Sox2, Nanog and Klf4. Trib2 directly interacted with Oct4 and elevated Oct4 promoter activity. During the generation of iPS cells, Trib2 knockdown decreased the reprogramming efficiency of mouse embryonic fibroblasts, whereas Trib2 overexpression significantly increased their reprogramming efficiency. In summary, our results suggest that Trib2 is important for maintaining self-renewal in ES cells and for pluripotency induction during the reprogramming process. PMID- 29170477 TI - Participation of GATA-3 in regulation of bone healing through transcriptional upregulation of bcl-xL expression. AB - We have previously demonstrated the expression of GATA-DNA-binding protein (GATA) 3, a transcription factor, in osteoblasts and have verified its function in transducing cell survival signaling. This translational study was further designed to evaluate the roles of GATA-3 in regulating bone healing and to explore its possible mechanisms. A metaphyseal bone defect was created in the left femurs of male ICR mice. Analysis by micro-computed topography showed that the bone volume, trabecular bone number and trabecular thickness were augmented and that the trabecular pattern factor decreased. Interestingly, immunohistological analyses showed specific expression of GATA-3 in the defect area. In addition, colocalized expression of GATA-3 and alkaline phosphatase was observed at the wound site. As the fracture healed, the amounts of phosphorylated and non-phosphorylated GATA-3 concurrently increased. Separately, GATA-3 mRNA was induced during bone healing, and, levels of Runx2 mRNA and protein were also increased. The results of confocal microscopy and co-immunoprecipitation showed an association between nuclear GATA-3 and Runx2 in the area of insult. In parallel with fracture healing, Bcl-XL mRNA was significantly triggered. A bioinformatic search revealed the existence of a GATA-3-specific DNA-binding element in the promoter region of the bcl-xL gene. Analysis by chromatin immunoprecipitation assays further demonstrated transactivation activity by which GATA-3 regulated bcl-xL gene expression. Therefore, this study shows that GATA-3 participates in the healing of bone fractures via regulating bcl-xL gene expression, owing to its association with Runx2. In the clinic, GATA-3 may be used as a biomarker for diagnoses/prognoses or as a therapeutic target for bone diseases, such as bone fractures. PMID- 29170478 TI - Therapeutic inhibition of SGK1 suppresses colorectal cancer. AB - Colorectal cancer (CRC) is one of the leading causes of death worldwide. Thus, the development of new therapeutic targets for CRC treatment is urgently needed. SGK1 is involved in various cellular activities, and its dysregulation can result in multiple cancers. However, little is known about its roles and associated molecular mechanisms in CRC. In present study, we found that SGK1 was highly expressed in tumor tissues compared with peri-tumor samples from CRC patients. In vitro experiments revealed that SGK1 overexpression promoted colonic tumor cell proliferation and migration and inhibited cell apoptosis induced by 5 fluorouracil (5-FU), while SGK1 shRNA and inhibitors showed the inverse effects. Using CRC xenograft mice models, we demonstrated that knockdown or therapeutic inhibition of SGK1 repressed tumor cell proliferation and tumor growth. Moreover, SGK1 inhibitors increased p27 expression and promoted p27 nuclear accumulation in colorectal cancer cells, and p27 siRNAs could attenuate the repression of CRC cell proliferation induced by SGK1 inhibitors. Collectively, SGK1 promotes colorectal cancer development via regulation of CRC cell proliferation, migration and survival. Inhibition of SGK1 represents a novel strategy for the treatment of CRC.

AB - Heme oxygenase-1-derived carbon monoxide prevents inflammatory vascular disorders. To date, there is no clear evidence that HO-1/CO prevents endothelial dysfunction associated with the downregulation of endothelial NO synthesis in human endothelial cells stimulated with TNF-alpha. Here, we found that the CO releasing compound CORM-2 prevented TNF-alpha-mediated decreases in eNOS expression and NO/cGMP production, without affecting eNOS promoter activity, by maintaining the functional activity of the eNOS mRNA 3'-untranslated region. By contrast, CORM-2 inhibited MIR155HG expression and miR-155-5p biogenesis in TNF alpha-stimulated endothelial cells, resulting in recovery of the 3'-UTR activity of eNOS mRNA, a target of miR-155-5p. The beneficial effect of CORM-2 was blocked by an NF-kappaB inhibitor, a miR-155-5p mimic, a HO-1 inhibitor and siRNA against HO-1, indicating that CO rescues TNF-alpha-induced eNOS downregulation through NF kappaB-responsive miR-155-5p expression via HO-1 induction; similar protective effects of ectopic HO-1 expression and bilirubin were observed in endothelial cells treated with TNF-alpha. Moreover, heme degradation products, except iron and N-acetylcysteine prevented H2O2-mediated miR-155-5p biogenesis and eNOS downregulation. These data demonstrate that CO prevents TNF-alpha-mediated eNOS downregulation by inhibiting redox-sensitive miR-155-5p biogenesis through a positive forward circuit between CO and HO-1 induction. This circuit may play an important preventive role in inflammatory endothelial dysfunction associated with human vascular diseases. PMID- 29170481 TI - Globular Shaped Polypyrrole Doped Well-Dispersed Functionalized Multiwall Carbon Nanotubes/Nafion Composite for Enzymatic Glucose Biosensor Application. AB - Herein, we report preparation of a bio-nanohybrid material of homogenously dispersed functionalized multiwall carbon nanotubes (fMWCNTs) in Nafion (Nf) doped with polypyrrole (PPy) and followed by one-step in situ electrochemical polymerization along with glucose oxidase (GOx) on a platinum (Pt) electrode. The bioengineered Nf-GOx-fMWCNTs-PPy/Pt electrode showed excellent electrocatalytic performance to detect glucose with a high sensitivity (54.2 MUAmM-1 cm-2) in linear range of up to 4.1 mM as well as a low detection limit of 5 MUM (S/N = 3), response time within 4 s, good selectivity, stability, and practical applicability. It is our hope that the comprehensive results will contribute to design an efficient glucose biosensor with practical prospects for biomedical applications. PMID- 29170482 TI - A New Approach to Deliver Anti-cancer Nanodrugs with Reduced Off-target Toxicities and Improved Efficiency by Temporarily Blunting the Reticuloendothelial System with Intralipid. AB - We have developed a new strategy to temporarily blunt the reticuloendothelial system uptake of nanodrugs, a major challenge for nanodrug delivery and causing off-target toxicities, using an FDA approved nutrition supplement, Intralipid. We have tested our methodology in rats using an experimental platinum-containing anti-cancer nanodrug and three FDA approved nanodrugs, Abraxane, Marqibo, and Onivyde, to determine their toxicities in liver, spleen, and kidney, with and without the addition of Intralipid. Our method illustrates its potentials to deliver nanodrugs with an increase in the bioavailability and a decrease in toxicities. Our study shows that Intralipid treatment exhibits no harmful effect on tumor growing and no negative effect on the anti-tumor efficacy of the platinum-containing nanodrug, as well as animal survival rate in a HT-29 xenograft mouse model. Our methodology could also be a valuable complement/supplement to the "stealth" strategies. Our approach is a general one applicable to any approved and in-development nanodrugs without additional modification of the nanodrugs, thus facilitating its translation to clinical settings. PMID- 29170483 TI - Free-running Sn precipitates: an efficient phase separation mechanism for metastable Ge1-xSnx epilayers. AB - The revival of interest in Ge1-xSnx alloys with x >= 10% is mainly owed to the recent demonstration of optical gain in this group-IV heterosystem. Yet, Ge and Sn are immiscible over about 98% of the composition range, which renders epilayers based on this material system inherently metastable. Here, we address the temperature stability of pseudomorphic Ge1-xSnx films grown by molecular beam epitaxy. Both the growth temperature dependence and the influence of post-growth annealing steps were investigated. In either case we observe that the decomposition of epilayers with Sn concentrations of around 10% sets in above ~230 degrees C, the eutectic temperature of the Ge/Sn system. Time-resolved in situ annealing experiments in a scanning electron microscope reveal the crucial role of liquid Sn precipitates in this phase separation process. Driven by a gradient of the chemical potential, the Sn droplets move on the surface along preferential crystallographic directions, thereby taking up Sn and Ge from the strained Ge1-xSnx layer. While Sn-uptake increases the volume of the melt, single crystalline Ge becomes re-deposited by a liquid-phase epitaxial process at the trailing edge of the droplet. This process makes phase separation of metastable GeSn layers particularly efficient at rather low temperatures. PMID- 29170484 TI - The evaluation of contralateral foot circulation after unilateral revascularization procedures using indocyanine green angiography. AB - The aim of the present study is to assess the effects of unilateral revascularization on the contralateral foot circulation using indocyanine green (ICG). From January 2016 to April 2016, a total of twenty-one patients were included in this study. The patients underwent elective unilateral revascularization at our institution and we evaluated the feet circulation by indocyanine green angiography (ICGA) tests preoperatively and postoperatively. The ICGA parameters included the magnitude of intensity from the onset of ICG to the maximum intensity (Imax), the time from the onset of ICG to the maximum intensity (Tmax), and the time required to reach the half maximum intensity from the onset of ICG (T1/2). There were significant differences in the treated limb Tmax (P = 0.016) and T1/2 (P = 0.013) values and in the contralateral limb Tmax (P = 0.013), and T1/2 (P < 0.001) values on the perioperative ICGA tests. These results reflect the increase in skin perfusion in the treated limb and the decrease in skin perfusion in the contralateral limb. Unilateral revascularization decreases contralateral foot circulation. The preoperative contralateral lesion should be evaluated when revascularization is performed.

AB - BACKGROUND/OBJECTIVES: Emulsified lipids, with central lipid core surrounded by polar lipid 'protective coat', have been proposed to stimulate the ileal brake, alter appetite, food intake and aid weight control. In addition to lipid composition, emulsion particle size may contribute to efficacy with small droplets providing a larger surface area for gastrointestinal (GI) lipase action and larger droplets prolonging and delaying digestion in the GI tract. Tube feeding studies delivering emulsions directly into the small intestine show clear effects of smaller particle size on appetite and food intake, but evidence from oral feeding studies is sparse. The objective of this study was to determine the effects of lipid emulsion particle size on appetite response and food intake. SUBJECTS/METHODS: In a three-arm randomised cross-over, high-phospholipid (PL) dairy lipid emulsions or matched control were consumed at breakfast within a yoghurt smoothie: (i) large-particle size emulsion, LPE (diameter 0.759 um, 10 g lipid emulsion, 190 g yoghurt), (ii) small-particle size emulsion, SPE (diameter 0.290 um, 10 g lipid emulsion, 190 g yoghurt), (iii) control non-emulsion, NE (10 g non-emulsion lipid, 190 g yoghurt). Twenty male participants completed the study, where postprandial appetite response was rated using visual analogue scales (VAS) and ad libitum energy intake at a lunch meal measured 3 h later. RESULTS: There was a trend for LPE to suppress hunger (P = 0.08) and enhance fullness (P = 0.24) relative to both SPE and NE but not statistically significant, and no significant effect of either emulsion on food intake at the lunch meal (P > 0.05). CONCLUSIONS: Altering particle size of a high-PL emulsion did not enhance satiety or alter eating behaviour in a group of lean men.

AB - Neural substrates behind schizophrenia (SZ) and its heritability mediated by brain function are largely unknown. Cerebral blood flow (CBF), as a biomarker of activation in the brain, reflects the neuronal metabolism, and is promisingly used to detect cerebral alteration thereby shedding light on the features of individuals at high genetic risk. We performed a cross-sectional functional magnetic resonance imaging (MRI) study enrolling 45 first-episode drug-naive patients with SZ, 32 unaffected first-degree relatives of these patients, and 51 healthy controls (HCs). We examined CBF, CBF connectivity, and CBF topological properties. SZ patients showed increased CBF in the left medial superior frontal gyrus and right precuneus compared with HCs, and decreased CBF in the left middle temporal gyrus compared with their relatives. Furthermore, unaffected relatives revealed higher level of CBF pronounced in regions within default mode network (DMN). Both SZ patients and their relatives exhibited dysconnectivity patterns. Notably, as for the network properties, unaffected relatives were with an intermediate level between SZ patients and HCs in the local efficiency and global efficiency. Our findings demonstrate the aberrant CBF of areas within DMN and the CBF connectivity pattern might be a familial feature in the brain of first episode SZ patients and their relatives.

AB - Histone lysine methyltransferases (KMTs) represent an important class of epigenetic enzymes that play essential roles in regulation of gene expression in humans. Members of the KMT family catalyze the transfer of the methyl group from S-adenosylmethionine (SAM) to lysine residues in histone tails and core histones. Here we report combined MALDI-TOF MS experiments, NMR analyses and quantum mechanical/molecular dynamics studies on human KMT-catalyzed methylation of the most related shorter and longer lysine analogues, namely ornithine and homolysine, in model histone peptides. Our experimental work demonstrates that while lysine is an excellent natural substrate for KMTs, ornithine and homolysine are not. This study reveals that ornithine does not undergo KMT-catalyzed methylation reactions, whereas homolysine can be methylated by representative examples of human KMTs. The results demonstrate that the specificity of KMTs is highly sensitive to the side chain length of the residue to be methylated. The origin for the degree of the observed activities of KMTs on ornithine and homolysine is discussed. PMID- 29170488 TI - Heme enables proper positioning of Drosha and DGCR8 on primary microRNAs. AB - MicroRNAs regulate the expression of many proteins and require specific maturation steps. Primary microRNA transcripts (pri-miRs) are cleaved by Microprocessor, a complex containing the RNase Drosha and its partner protein, DGCR8. Although DGCR8 is known to bind heme, the molecular role of heme in pri miR processing is unknown. Here we show that heme is critical for Microprocessor to process pri-miRs with high fidelity. Furthermore, the degree of inherent heme dependence varies for different pri-miRs. Heme-dependent pri-miRs fail to properly recruit Drosha, but heme-bound DGCR8 can correct erroneous binding events. Rather than changing the oligomerization state, heme induces a conformational change in DGCR8. Finally, we demonstrate that heme activates DGCR8 to recognize pri-miRs by specifically binding the terminal loop near the 3' single-stranded segment.

AB - A new bicentennial series of the Australian monsoon strength based on historical wind observations has allowed for the assessment of the variability of this system since the early 19th century. Our series covers a period in which the scarcity of meteorological observations in the area had precluded the evaluation of long-term climatic trends. Results indicate that the increase in precipitation over Northern Australia reported for the last 60 years is just a manifestation of a much longer lasting trend related to the strengthening of the Australian monsoon that has been occurring since at least 1816. PMID- 29170489 TI - Prokaryotic soluble expression and purification of bioactive human fibroblast growth factor 21 using maltose-binding protein. AB - Human fibroblast growth factor 21 (hFGF21) has been characterized as an important regulator of glucose and lipid metabolism homeostasis. Here, to produce hFGF21 efficiently in Escherichia coli, the expression and solubility of hFGF21 were tested and optimised by fusing the protein with one of eight tags: hexahistidine (His6), thioredoxin (Trx), small ubiquitin-related modifier (Sumo), glutathione S transferase (GST), maltose-binding protein (MBP), N-utilisation substance protein A (NusA), human protein disulphide isomerase (PDI), and the b'a' domain of PDI (PDIb'a'). Each tag increased solubility of the protein when the expression temperature was 18 degrees C. Unlike many other tags that were tested, MBP significantly enhanced the solubility of the protein also in the culture condition at 37 degrees C. Thus, the MBP-hFGF21 construct was further pursued for optimisation of affinity chromatography purification. After tag removal, 8.1 mg of pure hFGF21 was obtained as a final product from 500 mL of starting culture. The protein was then characterised by mass spectroscopy and an in vitro functional assay using NIH-3T3 cells transfected with a beta-klotho reporter gene. These characteristics are similar to those of commercial hFGF21. Thus, the MBP tag is useful for efficient prokaryotic production and purification of bioactive hFGF21.

AB - It is well known that surface energy differences thermodynamically stabilize nanocrystalline gamma-Al2O3 over alpha-Al2O3. Here, through correlative ab initio calculations and advanced material characterization at the nanometer scale, we demonstrate that the metastable phase formation of nanocrystalline TiAlN, an industrial benchmark coating material, is crystallite size-dependent. By relating calculated surface and volume energy contributions to the total energy, we predict the chemical composition-dependent phase boundary between the two metastable solid solution phases of cubic and wurzite Ti1-xAlxN. This phase boundary is characterized by the critical crystallite size d critical . Crystallite size-dependent phase stability predictions are in very good agreement with experimental phase formation data where x was varied by utilizing combinatorial vapor phase condensation. The wide range of critical Al solubilities for metastable cubic Ti1-xAlxN from x max = 0.4 to 0.9 reported in literature and the sobering disagreement thereof with DFT predictions can at least in part be rationalized based on the here identified crystallite size dependent metastable phase formation. Furthermore, it is evident that predictions of critical Al solubilities in metastable cubic TiAlN are flawed, if the previously overlooked surface energy contribution to the total energy is not considered. PMID- 29170492 TI - Prediction of plasma efavirenz concentrations among HIV-positive patients taking efavirenz-containing combination antiretroviral therapy. AB - We investigated the predictors of plasma mid-dose concentrations (C12) of efavirenz by enrolling 456 HIV-positive patients who had received 2 nucleos(t)ide reverse-transcriptase inhibitors plus efavirenz (600 mg daily) for 2 weeks or longer and had their CYP2B6 516G>T polymorphism and efavirenz C12 determined. The median efavirenz C12 was 2.41 mg/L (IQR, 1.93-3.14). In analysis of covariance models, patients with CYP2B6 516GT and TT genotypes compared to those with GG genotype had higher efavirenz C12 (for GT genotype, an increase by 0.976 mg/L [95%CI, 0.765-1.188], and TT genotype, 4.871 mg/L [95%CI, 4.126-5.616]), while per 10-kg increment in weight decreased C12 by 0.199 mg/L (95%CI, 0.111-0.287). Models incorporating CYP2B6 516G>T polymorphism and weight had moderate predictive values in predicting efavirenz C12 >= 2 mg/L (ROC area under curve = 0.706 [95%CI, 0.656-0.756]). In the absence of CYP2B6 516G>T polymorphism, weight <=58 kg provided better predictabilities for efavirenz C12 >= 2 mg/L (probability, 77.1% [95%CI, 69.0-83.5%] for weight = 50 kg and 70.6% [95%CI, 64.1 76.4%] for weight = 58 kg). PMID- 29170493 TI - The molecular basis of phosphite and hypophosphite recognition by ABC transporters. AB - Inorganic phosphate is the major bioavailable form of the essential nutrient phosphorus. However, the concentration of phosphate in most natural habitats is low enough to limit microbial growth. Under phosphate-depleted conditions some bacteria utilise phosphite and hypophosphite as alternative sources of phosphorus, but the molecular basis of reduced phosphorus acquisition from the environment is not fully understood. Here, we present crystal structures and ligand binding affinities of periplasmic binding proteins from bacterial phosphite and hypophosphite ATP-binding cassette transporters. We reveal that phosphite and hypophosphite specificity results from a combination of steric selection and the presence of a P-H...pi interaction between the ligand and a conserved aromatic residue in the ligand-binding pocket. The characterisation of high affinity and specific transporters has implications for the marine phosphorus redox cycle, and might aid the use of phosphite as an alternative phosphorus source in biotechnological, industrial and agricultural applications. PMID- 29170494 TI - Phosphate-Solubilizing Bacteria Nullify the Antagonistic Effect of Soil Calcification on Bioavailability of Phosphorus in Alkaline Soils. AB - Phosphate-solubilizing bacteria (PSB) reduce the negative effects of soil calcification on soil phosphorus (P) nutrition. In this incubation study, we explored the ability of PSB (control and inoculated) to release P from different P sources [single super phosphate (SSP), rock phosphate (RP), poultry manure (PM) and farm yard manure (FYM)] with various soil lime contents (4.78, 10, 15 and 20%) in alkaline soil. PSB inoculation progressively enriched Olsen extractable P from all sources compared to the control over the course of 56 days; however, this increase was greater from organic sources (PM and FYM) than from mineral P sources (SSP and RP). Lime addition to the soil decreased bioavailable P, but this effect was largely neutralized by PSB inoculation. PSB were the most viable in soil inoculated with PSB and amended with organic sources, while lime addition decreased PSB survival. Our findings imply that PSB inoculation can counteract the antagonistic effect of soil calcification on bioavailable P when it is applied using both mineral and organic sources, although organic sources support this process more efficiently than do mineral P sources. Therefore, PSB inoculation combined with organic manure application is one of the best options for improving soil P nutrition. PMID- 29170495 TI - First-trimester vaginal microbiome diversity: A potential indicator of preterm delivery risk. AB - Preterm birth is a leading cause of global neonate mortality. Hospitalization costs associated with preterm deliveries present a huge economic burden. Existing physical/biochemical markers for predicting preterm birth risk are mostly suited for application at mid/late pregnancy stages, thereby leaving very short time (between diagnosis and delivery) for adopting appropriate intervention strategies. Recent studies indicating correlations between pre/full-term delivery and the composition of vaginal microbiota in pregnant women have opened new diagnostic possibilities. In this study, we performed a thorough meta-analysis of vaginal microbiome datasets to evaluate the utility of popular diversity and inequality measures for predicting, at an early stage, the risk of preterm delivery. Results indicate significant differences (in diversity measures) between 'first-trimester' vaginal microbiomes obtained from women with term and preterm outcomes, indicating the potential diagnostic utility of these measures. In this context, we introduce a novel diversity metric that has significantly better diagnostic ability as compared to established diversity measures. The metric enables 'early' and highly accurate prediction of preterm delivery outcomes, and can potentially be deployed in clinical settings for preterm birth risk-assessment. Our findings have potentially far reaching implications in the fight against neonatal deaths due to preterm birth. PMID- 29170496 TI - Genome-wide analysis of circular RNAs in prenatal and postnatal pituitary glands of sheep. AB - Circular RNAs (circRNAs) are a class of animal non-coding RNAs and play an impor tant role in animal growth and development. However, the expression and function of circRNAs in the pituitary gland of sheep are unclear. Transcriptome profiling of circRNAs in the pituitary gland of sheep may enable us to understand their biological functions. In the present study, we identified 10,226 circRNAs from RNA-seq data in the pituitary gland of prenatal and postnatal sheep. Reverse transcription PCR and DNA sequencing analysis confirmed the presence of several circRNAs. Real-time RT-PCR analysis showed that sheep circRNAs are resistant to RNase R digestion and are expressed in prenatal and postnatal pituitary glands. GO and KEGG enrichment analysis showed that host genes of differentially expressed circRNAs are involved in the regulation of hormone secretion as well as in several pathways related to these processes. We determined that numerous circRNAs interact with pituitary-specific miRNAs that are involved in the biologic functions of the pituitary gland. Moreover, several circRNAs contain at least one IRES element and open reading frame, indicating their potential to encode proteins. Our study provides comprehensive expression profiles of circRNAs in the pituitary gland, thereby offering a valuable resource for circRNA biology in sheep. PMID- 29170497 TI - Divergent synthesis of N-heterocycles via controllable cyclization of azido diynes catalyzed by copper and gold. AB - Gold-catalyzed intermolecular alkyne oxidation by an N-O bond oxidant has proven to be a powerful method in organic synthesis during the past decade, because this approach would enable readily available alkynes as precursors in generating alpha oxo gold carbenes. Among those, gold-catalyzed oxidative cyclization of dialkynes has received particular attention as this chemistry offers great potential to build structurally complex cyclic molecules. However, these alkyne oxidations have been mostly limited to noble metal catalysts, and, to our knowledge, non noble metal-catalyzed reactions such as diyne oxidations have not been reported. Herein, we disclose a copper-catalyzed oxidative diyne cyclization, allowing the facile synthesis of a wide range of valuable pyrrolo[3,4-c]quinolin-1-ones. Interestingly, by employing the same starting materials, the gold-catalyzed cascade cyclization leads to the divergent formation of synthetically useful pyrrolo[2,3-b]indoles. Furthermore, the proposed mechanistic rationale for these cascade reactions is strongly supported by both control experiments and theoretical calculations. PMID- 29170498 TI - A structurally distinct TGF-beta mimic from an intestinal helminth parasite potently induces regulatory T cells. AB - Helminth parasites defy immune exclusion through sophisticated evasion mechanisms, including activation of host immunosuppressive regulatory T (Treg) cells. The mouse parasite Heligmosomoides polygyrus can expand the host Treg population by secreting products that activate TGF-beta signalling, but the identity of the active molecule is unknown. Here we identify an H. polygyrus TGF beta mimic (Hp-TGM) that replicates the biological and functional properties of TGF-beta, including binding to mammalian TGF-beta receptors and inducing mouse and human Foxp3+ Treg cells. Hp-TGM has no homology with mammalian TGF-beta or other members of the TGF-beta family, but is a member of the complement control protein superfamily. Thus, our data indicate that through convergent evolution, the parasite has acquired a protein with cytokine-like function that is able to exploit an endogenous pathway of immunoregulation in the host.

PMID- 29170499 TI - DNA double-strand break repair pathway regulates PD-L1 expression in cancer cells. AB - Accumulating evidence suggests that exogenous cellular stress induces PD-L1 upregulation in cancer. A DNA double-strand break (DSB) is the most critical type of genotoxic stress, but the involvement of DSB repair in PD-L1 expression has not been investigated. Here we show that PD-L1 expression in cancer cells is upregulated in response to DSBs. This upregulation requires ATM/ATR/Chk1 kinases. Using an siRNA library targeting DSB repair genes, we discover that BRCA2 depletion enhances Chk1-dependent PD-L1 upregulation after X-rays or PARP inhibition. In addition, we show that Ku70/80 depletion substantially enhances PD L1 upregulation after X-rays. The upregulation by Ku80 depletion requires Chk1 activation following DNA end-resection by Exonuclease 1. DSBs activate STAT1 and STAT3 signalling, and IRF1 is required for DSB-dependent PD-L1 upregulation. Thus, our findings reveal the involvement of DSB repair in PD-L1 expression and provide mechanistic insight into how PD-L1 expression is regulated after DSBs.

PMID- 29170503 TI - Mutational and putative neoantigen load predict clinical benefit of adoptive T cell therapy in melanoma. AB - Adoptive T-cell therapy (ACT) is a highly intensive immunotherapy regime that has yielded remarkable response rates and many durable responses in clinical trials in melanoma; however, 50-60% of the patients have no clinical benefit. Here, we searched for predictive biomarkers to ACT in melanoma. Whole exome- and transcriptome sequencing and neoantigen prediction were applied to pre-treatment samples from 27 patients recruited to a clinical phase I/II trial of ACT in stage IV melanoma. All patients had previously progressed on other immunotherapies. We report that clinical benefit is associated with significantly higher predicted neoantigen load. High mutation and predicted neoantigen load are significantly associated with improved progression-free and overall survival. Further, clinical benefit is associated with the expression of immune activation signatures including a high MHC-I antigen processing and presentation score. These results improve our understanding of mechanisms behind clinical benefit of ACT in melanoma. PMID- 29170504 TI - Characterization of large and small-plaque variants in the Zika virus clinical isolate ZIKV/Hu/S36/Chiba/2016. AB - An Asian/American lineage Zika virus (ZIKV) strain ZIKV/Hu/S36/Chiba/2016 formed 2 types in plaque size, large and small. Genomic analysis of the plaque-forming clones obtained from the isolate indicated that the clones forming small plaques commonly had an adenine nucleotide at position 796 (230Gln in the amino acid sequence), while clones forming large plaques had a guanine nucleotide (230Arg) at the same position, suggesting that this position was associated with the difference in plaque size. Growth kinetics of a large-plaque clone was faster than that of a small-plaque clone in Vero cells. Recombinant ZIKV G796A/rZIKV MR766, which carries a missense G796A mutation, was produced using an infectious molecular clone of the ZIKV MR766 strain rZIKV-MR766/pMW119-CMVP. The plaque size of the G796A mutant was significantly smaller than that of the parental strain. The G796A mutation clearly reduced the growth rate of the parental virus in Vero cells. Furthermore, the G796A mutation also decreased the virulence of the MR766 strain in IFNAR1 knockout mice. These results indicate that the amino acid variation at position 230 in the viral polyprotein, which is located in the M protein sequence, is a molecular determinant for plaque morphology, growth property, and virulence in mice of ZIKV. PMID- 29170505 TI - Ilizarov external fixation versus plate internal fixation in the treatment of end stage ankle arthritis: decision analysis of clinical parameters. AB - The purpose of this study was to evaluate the effect of Ilizarov external fixation (IEF) and plate internal fixation (PIF) in the treatment of end-stage ankle arthritis on pain relieving and function improvement. The study cohort consisted of 59 patients with end-stage ankle arthritis underwent ankle arthrodesis with IEF or PIF between June 2011 and June 2015. Standard radiographs and computed tomography (CT) scans were obtained before surgery and during the follow-up. Functional assessments were performed using Foot and Ankle pain score of American Orthopedics Foot and Ankle Society (AOFAS) and Visual Analogue Scale (VAS). The average AOFAS scores in both IEF group and PIF groups increased significantly after operation, from 45.5 +/- 6.3 to 84.8 +/- 4.9 and from 45.9 +/ 6.6 to 86.6 +/- 5.4, respectively. The average VAS scores in both groups decreased significantly after operation, from 8.4 +/- 1.9 to 2.5 +/- 0.6 and from 8.2 +/- 1.5 to 2.3 +/- 0.7, respectively. Nevertheless, there was no significant difference for preoperative or postoperative AOFAS and VAS scores between the two groups. The IEF would result in comparable postoperative functional recovery and pain relieving to PIF and may be an effective substitute to PIF in the treatment of end-stage ankle arthritis. PMID- 29170501 TI - Idiopathic REM sleep behaviour disorder and neurodegeneration - an update. AB - So-called idiopathic rapid eye movement (REM) sleep behaviour disorder (RBD), formerly seen as a rare parasomnia, is now recognized as the prodromal stage of an alpha-synucleinopathy. Given the very high risk that patients with idiopathic RBD have of developing alpha-synucleinopathies, such as Parkinson disease (PD), PD dementia, dementia with Lewy bodies or multiple system atrophy, and the outstandingly high specificity and very long interval between the onset of idiopathic RBD and the clinical manifestations of alpha-synucleinopathies, the prodromal phase of this disorder represents a unique opportunity for potentially disease-modifying intervention. This Review provides an update on classic and novel biomarkers of alpha-synuclein-related neurodegeneration in patients with idiopathic RBD, focusing on advances in imaging and neurophysiological, cognitive, autonomic, tissue-specific and other biomarkers. We discuss the strengths, potential weaknesses and suitability of these biomarkers for identifying RBD and neurodegeneration, with an emphasis on predicting progression to overt alpha-synucleinopathy. The role of video polysomnography in providing quantifiable and potentially treatment-responsive biomarkers of neurodegeneration is highlighted. In light of all these advances, and the now understood role of idiopathic RBD as an early manifestation of alpha-synuclein disease, we call for idiopathic RBD to be reconceptualized as isolated RBD. PMID- 29170506 TI - Daily Time-Use Patterns and Obesity and Mental Health among Primary School Students in Shanghai: A Population-Based Cross-Sectional Study. AB - Physical activity, screen viewing, sleep, and homework among children have been independently linked to health outcomes. However, few studies have assessed the independent associations between time spent in daily activities and children's physical and mental health. This study describes time spent in four activities among primary school students in Shanghai, and examines the relationship between daily time-use patterns and obesity and mental health. The representative sample consists of 17,318 children aged 6-11 years in Shanghai. Time spent in moderate to vigorous physical activities (MVPA), screen viewing, sleep, and homework was measured by validated questionnaires. Logistic regressions were performed. We also fitted generalized additive models (GAM) and performed two-objective optimization to minimize the probability of poor mental health and obesity. In 2014, 33.7% of children spent ?1 hour/day on MVPA, 15.6% spent >= 2 hours/day on screen viewing, 12.4% spent ? 9 hours/day on sleep, and 27.2% spent >= 2 hours/day on homework. The optimization results suggest that considering the 24 hour time limit, children face trade-offs when allocating time. A priority should be given to the duration of sleep and MVPA. Screen exposure should be minimized to save more time for sleep and other beneficial activities. PMID- 29170507 TI - Increased core body temperature in astronauts during long-duration space missions. AB - Humans' core body temperature (CBT) is strictly controlled within a narrow range. Various studies dealt with the impact of physical activity, clothing, and environmental factors on CBT regulation under terrestrial conditions. However, the effects of weightlessness on human thermoregulation are not well understood. Specifically, studies, investigating the effects of long-duration spaceflight on CBT at rest and during exercise are clearly lacking. We here show that during exercise CBT rises higher and faster in space than on Earth. Moreover, we observed for the first time a sustained increased astronauts' CBT also under resting conditions. This increase of about 1 degrees C developed gradually over 2.5 months and was associated with augmented concentrations of interleukin-1 receptor antagonist, a key anti-inflammatory protein. Since even minor increases in CBT can impair physical and cognitive performance, both findings have a considerable impact on astronauts' health and well-being during future long-term spaceflights. Moreover, our findings also pinpoint crucial physiological challenges for spacefaring civilizations, and raise questions about the assumption of a thermoregulatory set point in humans, and our evolutionary ability to adapt to climate changes on Earth. PMID- 29170508 TI - Differential distribution of Y-chromosome haplotypes in Swiss and Southern European goat breeds. AB - The analysis of Y-chromosome variation has provided valuable clues about the paternal history of domestic animal populations. The main goal of the current work was to characterize Y-chromosome diversity in 31 goat populations from Central Eastern (Switzerland and Romania) and Southern Europe (Spain and Italy) as well as in reference populations from Africa and the Near East. Towards this end, we have genotyped seven single nucleotide polymorphisms (SNPs), mapping to the SRY, ZFY, AMELY and DDX3Y Y-linked loci, in 275 bucks from 31 populations. We have observed a low level of variability in the goat Y-chromosome, with just five haplotypes segregating in the whole set of populations. We have also found that Swiss bucks carry exclusively Y1 haplotypes (Y1A: 24%, Y1B1: 15%, Y1B2: 43% and Y1C: 18%), while in Italian and Spanish bucks Y2A is the most abundant haplotype (77%). Interestingly, in Carpathian goats from Romania the Y2A haplotype is also frequent (42%). The high Y-chromosome differentiation between Swiss and Italian/Spanish breeds might be due to the post-domestication spread of two different Near Eastern genetic stocks through the Danubian and Mediterranean corridors. Historical gene flow between Southern European and Northern African goats might have also contributed to generate such pattern of genetic differentiation. PMID- 29170509 TI - Measuring tissue displacement of the anterior vaginal wall using the novel aspiration technique in vivo. AB - Little is known about the mechanical properties of pelvic floor structures and their role in the course and treatment of pelvic organ prolapse (POP). We hypothesize that in vivo mechanical properties of the vaginal wall are related to the appearance of POP and pre-and post-operative states. We used a suction device for intravaginal application, the aspiration device, to evaluate two in vivo mechanical parameters of the anterior vaginal wall, the load dependent tissue displacement and the initial displacement, by image analysis in pre- and post menopausal women with (POP) and without (control) cystocele (POP: pre-menopausal: N = 6, post-menopausal: N = 19, control: pre-menopausal: N = 17, post-menopausal: N = 6). Mechanical parameters in women with and without cystocele and pre- and post-operative parameters were compared. Statistically significant differences were observed between the two mechanical parameters in pre- and post-operative states (P = 0.04, P = 0.03), but not between the parameters for women with and without cystocele (P = 0.92, P = 0.75). The mechanical behavior of pelvic floor structures is influenced by factors such as POP, age or estrogenization that are apparent at different length scales, which cannot be separated by the aspiration based biomechanical measurements. When comparing pre- and post-operative states of the same patient, a firmer tissue response was observed after intervention. PMID- 29170510 TI - Whole blood stabilization for the microfluidic isolation and molecular characterization of circulating tumor cells. AB - Precise rare-cell technologies require the blood to be processed immediately or be stabilized with fixatives. Such restrictions limit the translation of circulating tumor cell (CTC)-based liquid biopsy assays that provide accurate molecular data in guiding clinical decisions. Here we describe a method to preserve whole blood in its minimally altered state by combining hypothermic preservation with targeted strategies that counter cooling-induced platelet activation. Using this method, whole blood preserved for up to 72 h can be readily processed for microfluidic sorting without compromising CTC yield and viability. The tumor cells retain high-quality intact RNA suitable for single cell RT-qPCR as well as RNA-Seq, enabling the reliable detection of cancer specific transcripts including the androgen-receptor splice variant 7 in a cohort of prostate cancer patients with an overall concordance of 92% between fresh and preserved blood. This work will serve as a springboard for the dissemination of diverse blood-based diagnostics. PMID- 29170511 TI - T cell-targeting nanoparticles focus delivery of immunotherapy to improve antitumor immunity. AB - Targeted delivery of compounds to particular cell subsets can enhance therapeutic index by concentrating their action on the cells of interest. Because attempts to target tumors directly have yielded limited benefit, we instead target endogenous immune cell subsets in the circulation that can migrate actively into tumors. We describe antibody-targeted nanoparticles that bind to CD8+ T cells in the blood, lymphoid tissues, and tumors of mice. PD-1+ T cells are successfully targeted in the circulation and tumor. The delivery of an inhibitor of TGFbeta signaling to PD-1-expressing cells extends the survival of tumor-bearing mice, whereas free drugs have no effect at such doses. This modular platform also enables PD-1 targeted delivery of a TLR7/8 agonist to the tumor microenvironment, increasing the proportion of tumor-infiltrating CD8+ T cells and sensitizing tumors to subsequent anti-PD-1. Targeted delivery of immunotherapy to defined subsets of endogenous leukocytes may be superior to administration of free drugs.

PMID- 29170512 TI - Generation of interspecies limited chimeric nephrons using a conditional nephron progenitor cell replacement system. AB - Animal fetuses and embryos may have applications in the generation of human organs. Progenitor cells may be an appropriate cell source for regenerative organs because of their safety and availability. However, regenerative organs derived from exogenous lineage progenitors in developing animal fetuses have not yet been obtained. Here, we established a combination system through which donor cells could be precisely injected into the nephrogenic zone and native nephron progenitor cells (NPCs) could be eliminated in a time- and tissue-specific manner. We successfully achieved removal of Six2+ NPCs within the nephrogenic niche and complete replacement of transplanted NPCs with donor cells. These NPCs developed into mature glomeruli and renal tubules, and blood flow was observed following transplantation in vivo. Furthermore, this artificial nephron could be obtained using NPCs from different species. Thus, this technique enables in vivo differentiation from progenitor cells into nephrons, providing insights into nephrogenesis and organ regeneration. PMID- 29170514 TI - Synthesis of uniform single layer WS2 for tunable photoluminescence. AB - Two-dimensional transition metal dichalcogenides (2D TMDs) have gained great interest due to their unique tunable bandgap as a function of the number of layers. Especially, single-layer tungsten disulfides (WS2) is a direct band gap semiconductor with a gap of 2.1 eV featuring strong photoluminescence and large exciton binding energy. Although synthesis of MoS2 and their layer dependent properties have been studied rigorously, little attention has been paid to the formation of single-layer WS2 and its layer dependent properties. Here we report the scalable synthesis of uniform single-layer WS2 film by a two-step chemical vapor deposition (CVD) method followed by a laser thinning process. The PL intensity increases six-fold, while the PL peak shifts from 1.92 eV to 1.97 eV during the laser thinning from few-layers to single-layer. We find from the analysis of exciton complexes that both a neutral exciton and a trion increases with decreasing WS2 film thickness; however, the neutral exciton is predominant in single-layer WS2. The binding energies of trion and biexciton for single-layer WS2 are experimentally characterized at 35 meV and 60 meV, respectively. The tunable optical properties by precise control of WS2 layers could empower a great deal of flexibility in designing atomically thin optoelectronic devices.

AB - Long non-coding RNAs (lncRNAs) were shown to be the crucial regulators of the many diseases. In this study, the expressions of lncRNAs were investigated in resected 158 hepatocellular carcinomas (HCCs) to evaluate the effects of their expression levels on prognosis. The expression levels of HULC and MALAT1 were shown to be significantly higher in the normal background tissue of HCC than those in the normal liver tissue of metastatic liver tumor without hepatitis (HULC: fold change 14.9, P = 1.7e-06; MALAT1: fold change 17.5, P = 1.2e-06. The formation of capsule was shown to be correlated with the increased expression of HULC (P = 0.041), while the size of HCC under 2 cm was correlated with a decrease in MALAT1 expression (P = 0.019). The levels of serum alpha-fetoprotein above 20 ng/mL indicated a decreased expression of both HULC and MALAT1 (HULC: P = 0.017; MALAT1: P = 0.0036). The increase in the expression levels of MALAT1 in HCC tissues was significantly correlated with better overall survival (HULC: P = 0.099, MALAT1: P = 0.028). Thus, the expression of these lncRNAs in HCC potentially correlates with the HCC malignancy and they represent potential prognostic biomarkers of the resected HCC.

AB - The new oncologic paradigm of precision medicine is focused on identifying metabolic, proteomic, transcriptomic and genomic variabilities in tumors that can be exploited to tailor treatments and improve patient outcomes. Metabolic changes are a hallmark of cancer, and inhibition of metabolic pathways is now a major strategy in medicinal chemistry for targeting cancers. However, non-invasive biomarkers to categorize metabolic subtypes are in short supply. The purpose of this study was to characterize the intracellular and extracellular metabolic profiles of four prostate cancer cell lines with varying degrees of aggressiveness. We observed metabolic differences between the aggressive prostate cancer cell line PC3 and the even more aggressive, metastatic subline PC3M assessed by hyperpolarized in vivo pyruvate studies, nuclear magnetic resonance spectroscopy, and carbon-13 feeding studies. On further examination of the differences between these two cell lines, we found increased glutamine utilization in the metastatic PC3M subline that led directly to sensitivity to glutaminase inhibitor CB-839. Our study supports the theory that metastatic progression increases glutamine utilization and the inhibition of glutaminolysis could have clinical implications. PMID- 29170517 TI - Direct evidence of multichannel-improved charge-carrier mechanism for enhanced photocatalytic H2 evolution. AB - In the field of photocatalysis, the high-charge recombination rate has been the big challenge to photocatalytic conversion efficiency. Here we demonstrate the direct evidence of multichannel-improved charge-carrier mechanism to facilitate electron-hole transfer for raising photocatalytic H2 evolution activity. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and UV-Vis diffuse reflectance spectroscopy (DRS), were used to characterize the as-fabricated samples. The result shows that the present design of Au/Pt nanoparticles (NPs) decorated one-dimensional Z-scheme TiO2/WO3 heterostructure composite nanofibers have been fabricated, which even exhibited excellent light absorption in the visible region and greatly enhanced photocatalytic activities on H2 generation comparing with pure TiO2, TiO2/WO3 and Pt/WO3/TiO2 nanofibers. This greatpromotion is mainly on account of the photosynthetic heterojunction system, which include the surface plasmon resonance (SPR) of Au nanoparticles, low overpotential of Pt nanoparticles, and more importantly, the one-dimensional multichannel-improved charge-carrier photosynthetic heterojunction system with Pt as an electron collector and WO3 as a hole collector. Transferring photoinduced electrons and holes at the same time, leading to effective charge separation was directly proved by ultraviolet photoelectron spectroscopy, electrochemical impedance spectroscopy, photocurrent analysis and incident photon-to-electron conversion spectrum. PMID- 29170518 TI - Second messenger analogues highlight unexpected substrate sensitivity of CD38: total synthesis of the hybrid "L-cyclic inosine 5'-diphosphate ribose". AB - The multifunctional, transmembrane glycoprotein human CD38 catalyses the synthesis of three key Ca2+-mobilising messengers, including cyclic adenosine 5' diphosphate ribose (cADPR), and CD38 knockout studies have revealed the relevance of the related signalling pathways to disease. To generate inhibitors of CD38 by total synthesis, analogues based on the cyclic inosine 5'-diphosphate ribose (cIDPR) template were synthesised. In the first example of a sugar hybrid cIDPR analogue, "L-cIDPR", the natural "northern" N1-linked D-ribose of cADPR was replaced by L-ribose. L-cIDPR is surprisingly still hydrolysed by CD38, whereas 8 Br-L-cIDPR is not cleaved, even at high enzyme concentrations. Thus, the inhibitory activity of L-cIDPR analogues appears to depend upon substitution of the base at C-8; 8-Br-L-cIDPR and 8-NH2-L-cIDPR inhibit CD38-mediated cADPR hydrolysis (IC50 7 MUM and 21 uM respectively) with 8-Br-L-cIDPR over 20-fold more potent than 8-Br-cIDPR. In contrast, L-cIDPR displays a comparative 75-fold reduction in activity, but is only ca 2-fold less potent than cIDPR itself. Molecular modelling was used to explore the interaction of the CD38 catalytic residue Glu-226 with the "northern" ribose. We propose that Glu226 still acts as the catalytic residue even for an L-sugar substrate. 8-Br-L-cIDPR potentially binds non-productively in an upside-down fashion. Results highlight the key role of the "northern" ribose in the interaction of cADPR with CD38. PMID- 29170519 TI - Plasmonic enhanced low-threshold random lasing from dye-doped nematic liquid crystals with TiN nanoparticles in capillary tubes. AB - We report a plasmonic enhanced low-threshold random lasing from dye-doped nematic liquid crystals with titanium nitride (TiN) nanoparticles (NPDDNLC) in capillary tubes. The NPDDNLC sample yields a coherent random laser with about 0.3 nm in the full width at half maximum (FWHM). We find the laser threshold is decreased by introducing the TiN NPs into the dye-doped nematic liquid crystal sample. The laser threshold decreases with increasing the number density of TiN nanoparticles from 5.613 * 1010/ml to 5.314 * 1011/ml. We suggest that the low-threshold random laser is caused by the cooperative effect of the recurrent multiple scattering and field enhancement in the vicinity of TiN nanoparticles. The localized electric field near the TiN nanoparticles enhances the energy absorption of the dye and strengthens the fluorescence amplification. Moreover, we provide a new parameter (the relative efficiency of the stimulated radiation photons) to quantify the quality of the random laser, and we give expressions for the wavelength, mode, and whole emission spectrum. Finally, we find the emission spectrum depends strongly on the emission angle and we discuss the reasons. These findings provide a simple and efficient way for the realization of low-threshold random lasers with low cost. PMID- 29170520 TI - Integrated Proteomic and Metabolomic prediction of Term Preeclampsia. AB - Term preeclampsia (tPE), >=37 weeks, is the most common form of PE and the most difficult to predict. Little is known about its pathogenesis. This study aims to elucidate the pathogenesis and assess early prediction of tPE using serial integrated metabolomic and proteomic systems biology approaches. Serial first- (11-14 weeks) and third-trimester (30-34 weeks) serum samples were analyzed using targeted metabolomic (1H NMR and DI-LC-MS/MS) and proteomic (MALDI-TOF/TOF-MS) platforms. We analyzed 35 tPE cases and 63 controls. Serial first- (sphingomyelin C18:1 and urea) and third-trimester (hexose and citrate) metabolite screening predicted tPE with an area under the receiver operating characteristic curve (AUC) (95% CI) = 0.817 (0.732-0.902) and a sensitivity of 81.6% and specificity of 71.0%. Serial first [TATA box binding protein-associated factor (TBP)] and third-trimester [Testis-expressed sequence 15 protein (TEX15)] protein biomarkers highly accurately predicted tPE with an AUC (95% CI) of 0.987 (0.961-1.000), sensitivity 100% and specificity 98.4%. Integrated pathway over-representation analysis combining metabolomic and proteomic data revealed significant alterations in signal transduction, G protein coupled receptors, serotonin and glycosaminoglycan metabolisms among others. This is the first report of serial integrated and combined metabolomic and proteomic analysis of tPE. High predictive accuracy and potentially important pathogenic information were achieved. PMID- 29170521 TI - Age-dependent and regional heterogeneity in the long-chain base of A-series gangliosides observed in the rat brain using MALDI Imaging. AB - Alterations in the long chain base of the sphingosine moiety of gangliosides have been shown to play a role in neurodevelopment and neurodegeneration. Indeed, the accumulation of d20:1 sphingosine has been referred to as a metabolic marker of aging in the brain, however, this remains to be shown in simple gangliosides GM2 and GM3. In this study, Matrix-assisted laser desorption/ionization Imaging Mass Spectrometry (MALDI IMS) was used to examine the neuroanatomical distribution of A-series gangliosides with either 18 or 20 carbon sphingosine chains (d18:1 or d20:1) in Fisher 344 rats across the lifespan. The ratio of d20:1/d18:1 species was determined across 11 regions of interest in the brain. Interestingly, a decrease in the d20:1/d18:1 ratio for GM2 and GM3 was observed during early development with the exception of the peri-ventricular corpus callosum, where an age-dependent increase was observed for ganglioside GM3. An age-dependent increase in d20:1 species was confirmed for complex gangliosides GM1 and GD1 with the most significant increase during early development and a high degree of anatomical heterogeneity during aging. The unique neuroanatomically-specific responses of d20:1 ganglioside abundance may lead to a better understanding of regional vulnerability to damage in the aging brain. PMID- 29170522 TI - Elevation in tropical sky islands as the common driver in structuring genes and communities of freshwater organisms. AB - Tropical mountains are usually characterized by a vertically-arranged sequence of ecological belts, which, in contrast to temperate habitats, have remained relatively stable in space across the Quaternary. Such long-lasting patterning of habitats makes them ideal to test the role of environmental pressure in driving ecological and evolutionary processes. Using Sumatran freshwater mayfly communities, we test whether elevation, rather than other spatial factors (i.e. volcanoes, watersheds) structures both species within communities and genes within species. Based on the analysis of 31 mayfly (Ephemeroptera) communities and restriction-site-associated-DNA sequencing in the four most ubiquitous species, we found elevation as the major spatial component structuring both species and genes in the landscape. In other words, similar elevations across different mountains or watersheds harbor more similar species and genes than different elevations within the same mountain or watershed. Tropical elevation gradients characterized by environmental conditions that are both steep and relatively stable seasonally and over geological time scales, are thus responsible for both ecological and genetic differentiation. Our results demonstrate how in situ ecological diversification at the micro-evolutionary level might fuel alpha- and beta- components of diversity in tropical sky islands. PMID- 29170523 TI - Stochastic evolutionary voluntary public goods game with punishment in a Quasi birth-and-death process. AB - Traditional replication dynamic model and the corresponding concept of evolutionary stable strategy (ESS) only takes into account whether the system can return to the equilibrium after being subjected to a small disturbance. In the real world, due to continuous noise, the ESS of the system may not be stochastically stable. In this paper, a model of voluntary public goods game with punishment is studied in a stochastic situation. Unlike the existing model, we describe the evolutionary process of strategies in the population as a generalized quasi-birth-and-death process. And we investigate the stochastic stable equilibrium (SSE) instead. By numerical experiments, we get all possible SSEs of the system for any combination of parameters, and investigate the influence of parameters on the probabilities of the system to select different equilibriums. It is found that in the stochastic situation, the introduction of the punishment and non-participation strategies can change the evolutionary dynamics of the system and equilibrium of the game. There is a large range of parameters that the system selects the cooperative states as its SSE with a high probability. This result provides us an insight and control method for the evolution of cooperation in the public goods game in stochastic situations. PMID- 29170524 TI - Quantitative analysis of motor evoked potentials in the neonatal lamb. AB - Evoking motor potentials are an objective assessment method for neuromotor function, yet this was to our knowledge never done in neonatal lambs. There is neither a method for standardized quantification of motor evoked potentials (MEPs). We first aimed to evaluate the feasibility of MEP recording in neonatal lambs and test its validity. Second we aimed to develop an algorithm for its quantification and test its reliability since manual input is required. We recorded myogenic MEPs after transcranial motor cortex stimulation in 6 lambs aged 1-2 days. MEPs were also measured in one lamb undergoing Neuro-Muscular Blockade (NMB) and another undergoing lumbar spinal cord (SC) transection, both serving as controls. We computed 5 parameters using a custom-made algorithm: motor threshold, latency, area-under-the-curve, peak-to-peak amplitude and duration. Intra- and inter-observer reliability was analyzed. MEPs could be easily recorded, disappearing after NMB and SC transection. The algorithm allowed for analysis, hence physiologic readings of the parameters in all 4 limbs of all lambs were obtained. Our method was shown to have high intra- and inter-observer ( >=70%) reliability for latency, area-under-the-curve and peak-to-peak amplitude. These results suggest that standardized MEP recording and analysis in neonatal lambs is feasible, and can reliably assess neuromotor function. PMID- 29170525 TI - Advanced glycation endproducts link inflammatory cues to upregulation of galectin 1 in diabetic retinopathy. AB - Diabetic retinopathy (DR) is an inflammatory and progressive vaso-occlusive disease resulting in angiogenesis. Galectin-1 is a hypoxia-induced angiogenic factor associated with cancer and proliferative DR. Here we reveal a significant upregulation of galectin-1 in eyes of DR patients along with progression of clinical stages beginning from the pre-ischemic, inflammatory stage with diabetic macular edema, but not in eyes with non-diabetic retinal vascular occlusions. As for its regulatory mechanism unrelated to hypoxia but selective to DR, in vitro galectin-1/LGALS1 expression was shown to increase after application to Muller glial cells with interleukin (IL)-1beta, which was induced in monocyte-derived macrophages and microglial cells via toll-like receptor (TLR) 4 signaling stimulated by advanced glycation endproducts (AGE). In vivo inhibition of AGE generation with aminoguanidine, macrophage depletion with clodronate liposomes, and antibody-based blockade of Il-1beta and Tlr4 attenuated diabetes-induced retinal Lgals1 expression in mice. Fibrovascular tissues from proliferative DR eyes were immunoreactive for AGE, TRL4 and IL-1beta in macrophages, and IL-1beta receptor-positive glial cells expressed galectin-1. Therefore, diabetes-induced retinal AGE accumulation was suggested to activate IL-1beta-related inflammatory cues in macrophages followed by Muller cells, linking to galectin-1 upregulation in human DR with time. Our data highlight AGE-triggered inflammation as the DR selective inducer of galectin-1. PMID- 29170526 TI - Driver pattern identification over the gene co-expression of drug response in ovarian cancer by integrating high throughput genomics data. AB - Multiple types of high throughput genomics data create a potential opportunity to identify driver patterns in ovarian cancer, which will acquire some novel and clinical biomarkers for appropriate diagnosis and treatment to cancer patients. To identify candidate driver genes and the corresponding driving patterns for resistant and sensitive tumors from the heterogeneous data, we combined gene co expression modules with mutation modulators and proposed the method to identify driver patterns. Firstly, co-expression network analysis is applied to explore gene modules for gene expression profiles through weighted correlation network analysis (WGCNA). Secondly, mutation matrix is generated by integrating the CNV data and somatic mutation data, and a mutation network is constructed from the mutation matrix. Thirdly, candidate modulators are selected from significant genes by clustering vertexs of the mutation network. Finally, a regression tree model is utilized for module network learning, in which the obtained gene modules and candidate modulators are trained for the driving pattern identification and modulators regulatory exploration. Many identified candidate modulators are known to be involved in biological meaningful processes associated with ovarian cancer, such as CCL11, CCL16, CCL18, CCL23, CCL8, CCL5, APOB, BRCA1, SLC18A1, FGF22, GADD45B, GNA15, GNA11, and so on. PMID- 29170527 TI - Theoretical investigations on microwave Fano resonances in 3D-printable hollow dielectric resonators. AB - High-index dielectric structures have recently been studied intensively for Mie resonances at optical frequencies. These dielectric structures can enable extreme light manipulation, similar to that which has been achieved with plasmonic nanostructures. In the microwave region, dielectric resonators and metamaterials can be fabricated directly using 3D printing, which is advantageous for fabricating structurally complicated 3D geometries. It is therefore especially suitable for the fabrication of subwavelength structures. Here we report theoretical investigations on microwave Fano resonances in 3D-printable dielectric materials and structures. In particular, we propose and analyse 3D printable, hollow, dielectric resonators with relatively low refractive indices, which exhibit sharp Fano resonances. We can control the interaction between bright and dark modes in a coupled dielectric particle pair by adjusting the inner-hole size, and thus we can increase the radiative Q factors further. We also find that Fano resonances in these hollow dielectric resonators are very sensitive to an index change in the surrounding medium, which could be useful for long-distance environmental sensing. New possibilities and opportunities are opening up with the rapid development of 3D-printing technologies. Our findings and the detailed investigations reported here can provide useful guidelines for future photonic devices based on 3D-printable materials and structures. PMID- 29170528 TI - Kidney Androgen-Regulated Protein (KAP) Transgenic Mice Are Protected Against High-Fat Diet Induced Metabolic Syndrome. AB - Metabolic Syndrome (MS) is reaching epidemic proportions with significant social and economical burden worldwide. Since the molecular basis of MS remains poorly defined, we investigated the impact of KAP, a kidney specific androgen-regulated gene, in the development of high fat-diet (hfd)-induced MS. Tg mice overexpressing KAP specifically in proximal tubule cells of the kidney exhibited reduced body weight and lower liver and adipose tissue weight compared to control littermates when fed a hfd. KAP Tg mice showed diminished adipocyte hypertrophy and reduced hepatic steatosis, significantly correlating with expression of relevant molecular markers and lower lipid content in liver. KAP transgenic were protected from hfd-induced insulin resistance, increased blood pressure and exhibited lower IL-6 serum levels and diminished expression of inflammatory markers in the adipose. Moreover, KAP was localized in the secretory pathway of proximal tubule cells and it is released to the extracellular media, preventing IL-6 induction and STAT-3 activation upon TNFalpha stimulation. We conclude that KAP, which might act as a hormone-like product in extra-renal tissues, protects Tg mice against hfd-induced MS by preventing inflammatory related events that are mediated, in part, through the IL-6 pathway. PMID- 29170529 TI - Visual analysis of mass cytometry data by hierarchical stochastic neighbour embedding reveals rare cell types. AB - Mass cytometry allows high-resolution dissection of the cellular composition of the immune system. However, the high-dimensionality, large size, and non-linear structure of the data poses considerable challenges for the data analysis. In particular, dimensionality reduction-based techniques like t-SNE offer single cell resolution but are limited in the number of cells that can be analyzed. Here we introduce Hierarchical Stochastic Neighbor Embedding (HSNE) for the analysis of mass cytometry data sets. HSNE constructs a hierarchy of non-linear similarities that can be interactively explored with a stepwise increase in detail up to the single-cell level. We apply HSNE to a study on gastrointestinal disorders and three other available mass cytometry data sets. We find that HSNE efficiently replicates previous observations and identifies rare cell populations that were previously missed due to downsampling. Thus, HSNE removes the scalability limit of conventional t-SNE analysis, a feature that makes it highly suitable for the analysis of massive high-dimensional data sets. PMID- 29170530 TI - Identification and analysis of seven effector protein families with different adaptive and evolutionary histories in plant-associated members of the Xanthomonadaceae. AB - The Xanthomonadaceae family consists of species of non-pathogenic and pathogenic gamma-proteobacteria that infect different hosts, including humans and plants. In this study, we performed a comparative analysis using 69 fully sequenced genomes belonging to this family, with a focus on identifying proteins enriched in phytopathogens that could explain the lifestyle and the ability to infect plants. Using a computational approach, we identified seven phytopathogen-enriched protein families putatively secreted by type II secretory system: PheA (CM-sec), LipA/LesA, VirK, and four families involved in N-glycan degradation, NixE, NixF, NixL, and FucA1. In silico and phylogenetic analyses of these protein families revealed they all have orthologs in other phytopathogenic or symbiotic bacteria, and are involved in the modulation and evasion of the immune system. As a proof of concept, we performed a biochemical characterization of LipA from Xac306 and verified that the mutant strain lost most of its lipase and esterase activities and displayed reduced virulence in citrus. Since this study includes closely related organisms with distinct lifestyles and highlights proteins directly related to adaptation inside plant tissues, novel approaches might use these proteins as biotechnological targets for disease control, and contribute to our understanding of the coevolution of plant-associated bacteria. PMID- 29170532 TI - Active Sites of M(IV)-incorporated Zeolites (M = Sn, Ti, Ge, Zr). AB - M(IV)-incorporated zeolites have recently aroused wide interest due to outstanding catalytic effects while their active sites remain largely elusive. Here periodic density functional theory calculations are conducted finding that active sites are determined jointly by identity of M(IV) ions, topology of zeolites, type of framework species and choice of T sites. All M2(IV) active sites in BEA zeolites are penta-coordinated with chemisorption of one water while subsequent water molecules that form only H-bonds promote chemisorption of the first water, especially the second water possessing comparable or even higher adsorption strengths as the first water; Ti(IV) and Ge(IV) active sites at the intersection remain penta-coordinated and Sn(IV) and Zr(IV) active sites prefer to hexa-coordination although potentially expanded to hepta-coordination. Different from other zeolites, Ti(IV) active sites in FER zeolites are hexa coordinated as Sn(IV) active sites, due to the promoting effect of the first water. Lewis acidic defects expand Ti(IV) active sites to hexa-coordination while inhibit the formation of hepta-coordinated Sn(IV) species. Two forms of Brphinsted acidic defects exist for Sn(IV) sites instead of only one for Ti(IV) sites, and all M(IV) Brphinsted acidic defects, regardless of different acidic forms and M(IV) ions, can chemisorb only one water. PMID- 29170531 TI - Analysis of the respiratory component of heart rate variability in the Cururu toad Rhinella schneideri. AB - Beat-to-beat variation in heart rate (f H ) has been used as a tool for elucidating the balance between sympathetic and parasympathetic modulation of the heart. A portion of the temporal changes in f H is evidenced by a respiratory influence (cardiorespiratory interaction) on heart rate variability (HRV) with heartbeats increasing and decreasing within a respiratory cycle. Nevertheless, little is known about respiratory effects on HRV in lower vertebrates. By using frequency domain analysis, we provide the first evidence of a ventilatory component in HRV similar to mammalian respiratory sinus arrhythmia in an amphibian, the toad Rhinella schneideri. Increases in the heartbeats arose synchronously with each lung inflation cycle, an intermittent breathing pattern comprised of a series of successive lung inflations. A well-marked peak in the HRV signal matching lung inflation cycle was verified in toads whenever lung inflation cycles exhibit a regular rhythm. The cardiac beat-to-beat variation evoked at the moment of lung inflation accounts for both vagal and sympathetic influences. This cardiorespiratory interaction may arise from interactions between central and peripheral feedback mechanisms governing cardiorespiratory control and may underlie important cardiorespiratory adjustments for gas exchange improvement especially under extreme conditions like low oxygen availability. PMID- 29170533 TI - Equilibrium folding dynamics of meACP in water, heavy water, and low concentration of urea. AB - Many proteins fold in apparent two-state behavior, as partially folded intermediates only transiently accumulate and easily escape detection. Besides a native form and a mainly unfolded form, we captured a partially unfolded form of an acyl carrier protein from Micromonospora echinospora (meACP) in the folding/unfolding equilibrium using chemical exchange saturation transfer NMR experiments. The C-terminal region of the partially unfolded form is mainly folded and the N-terminal is unfolded. Furthermore, to understand how the folding process of meACP is influenced by solvent environments, we compared the folding dynamics of meACP in D2O, H2O and low concentration of urea. As the environment becomes more denaturing from D2O to H2O and then to urea, the unfolded state becomes increasingly populated, and the folding rate decreases. Adding a small amount of urea, which does not change solvent viscosity, has little effects on the unfolding rates, while changing H2O to D2O reduces the unfolding rates possibly due to the increase of solvent viscosity. The quantified solvent effects on the protein folding Gibbs energy and activation energy suggest that the transition state of folding may have a similar structure to the native state of the protein. PMID- 29170534 TI - Increased serum vascular endothelial growth factor is associated with acute viral encephalitis in Bangladeshi children. AB - Encephalitis causes significant global morbidity and mortality. A large number of viruses cause encephalitis, and their geographic and temporal distributions vary. In many encephalitis cases, the virus cannot be detected, even after extensive testing. This is one challenge in management of the encephalitis patient. Since cytokines are pivotal in any form of inflammation and vary according to the nature of the inflammation, we hypothesized cytokine levels would allow us to discriminate between encephalitis caused by viruses and other aetiologies. This pilot study was conducted in a tertiary care hospital in Dhaka, Bangladesh. Viral detection was performed by polymerase chain reaction using patient cerebrospinal fluid. Acute phase reactants and cytokines were detected in patient serum. Of the 29 biomarkers assessed using the Wilcoxon rank-sum test, only vascular endothelial growth factor (VEGF) was significantly higher (P = 0.0015) in viral positive compared with virus-negative encephalitis patients. The area under the curve (AUC) for VEGF was 0.82 (95% confidence interval: 0.66-0.98). Serum VEGF may discriminate between virus-positive and virus-negative encephalitis. Further study will be needed to confirm these findings. PMID- 29170535 TI - Rapid Detection of Prunus Necrotic Ringspot Virus by Reverse Transcription-cross priming Amplification Coupled with Nucleic Acid Test Strip Cassette. AB - Prunus necrotic ringspot virus (PNRSV) is one of the most devastating viruses to Prunus spp. In this study, we developed a diagnostic system RT-CPA-NATSC, wherein reverse transcription-cross-priming amplification (RT-CPA) is coupled with nucleic acid test strip cassette (NATSC), a vertical flow (VF) visualization, for PNRSV detection. The RT-CPA-NATSC assay targets the encoding gene of the PNRSV coat protein with a limit of detection of 72 copies per reaction and no cross reaction with the known Prunus pathogenic viruses and viroids, demonstrating high sensitivity and specificity. The reaction is performed on 60 degrees C and can be completed less than 90 min with the prepared template RNA. Field sample test confirmed the reliability of RT-CPA-NATSC, indicating the potential application of this simple and rapid detection method in routine test of PNRSV.

PMID- 29170536 TI - Non-coding RNA networks in cancer. AB - Thousands of unique non-coding RNA (ncRNA) sequences exist within cells. Work from the past decade has altered our perception of ncRNAs from 'junk' transcriptional products to functional regulatory molecules that mediate cellular processes including chromatin remodelling, transcription, post-transcriptional modifications and signal transduction. The networks in which ncRNAs engage can influence numerous molecular targets to drive specific cell biological responses and fates. Consequently, ncRNAs act as key regulators of physiological programmes in developmental and disease contexts. Particularly relevant in cancer, ncRNAs have been identified as oncogenic drivers and tumour suppressors in every major cancer type. Thus, a deeper understanding of the complex networks of interactions that ncRNAs coordinate would provide a unique opportunity to design better therapeutic interventions. PMID- 29170537 TI - Hippocampal MRS and subfield volumetry at 7T detects dysfunction not specific to seizure focus. AB - Ultra high-field 7T MRI offers sensitivity to localize hippocampal pathology in temporal lobe epilepsy (TLE), but has rarely been evaluated in patients with normal-appearing clinical MRI. We applied multimodal 7T MRI to assess if focal subfield atrophy and deviations in brain metabolites characterize epileptic hippocampi. Twelve pre-surgical TLE patients (7 MRI-negative) and age-matched healthy volunteers were scanned at 7T. Hippocampal subfields were manually segmented from 600MUm isotropic resolution susceptibility-weighted images. Hippocampal metabolite spectra were acquired to determine absolute concentrations of glutamate, glutamine, myo-inositol, NAA, creatine and choline. We performed case-controls analyses, using permutation testing, to identify abnormalities in hippocampal imaging measures in individual patients, for evaluation against clinical evidence of seizure lateralisation and neuropsychological memory test scores. Volume analyses identified hippocampal subfield atrophy in 9/12 patients (75%), commonly affecting CA3. 7/8 patients had altered metabolite concentrations, most showing reduced glutamine levels (62.5%). However, neither volume nor metabolite deviations consistently lateralized the epileptogenic hippocampus. Rather, lower subiculum volumes and glutamine concentrations correlated with impaired verbal memory performance. Hippocampal subfield and metabolic abnormalities detected at 7T appear to reflect pathophysiological processes beyond epileptogenesis. Despite limited diagnostic contributions, these markers show promise to help elucidate mnemonic processing in TLE.

AB - In this paper, we have investigated the structural, electronic, magnetic, half metallic, mechanical, and thermodynamic properties of the equiatomic quaternary Heusler (EQH) compound FeCrRuSi using the density functional theory (DFT) and the quasi-harmonic Debye model. Our results reveal that FeCrRuSi is a half-metallic material (HMM) with a total magnetic moment of 2.0 MUB in agreement with the well known Slater-Pauling rule Mt = Zt - 24. Furthermore, the origin of the half metallic band gap in FeCrRuSi is well studied through a schematic diagram of the possible d-d hybridization between Fe, Cr and Ru elements. The half-metallic behavior of FeCrRuSi can be maintained in a relatively wide range of variations of the lattice constant (5.5-5.8 A) under uniform strain and the c/a ratio (0.96 1.05) under tetragonal distortion. The calculated phonon dispersion, cohesive and formation energies, and mechanical properties reveal that FeCrRuSi is stable with an EQH structure. Importantly, the compound of interest has been prepared and is found to exist in an EQH type structure with the presence of some B2 disorder. Moreover, the thermodynamic properties, such as the thermal expansion coefficient alpha, the heat capacity CV, the Gruneisen constant gamma, and the Debye temperature ThetaD are calculated. PMID- 29170543 TI - Long-term effects of adolescent obesity: time to act. AB - Obesity in adolescence will probably have major implications not only for the affected adolescents but also for society. Those who have obesity during adolescence usually have obesity into adulthood, which causes many medical and psychological issues that can result in premature death. Furthermore, obesity in adolescents is associated with a range of social problems, including difficulties securing an apprenticeship or a job or finding a partner. Adolescents with obesity are also at increased risk of having children with obesity later in life. All these consequences lead to high costs for the health-care system. Although efficient treatment options are available that have been proven in randomized controlled trials, such as lifestyle interventions for adolescents with obesity and bariatric surgery for adolescents with severe obesity, these interventions frequently fail in clinical practice as treatment adherence is low in adolescents and most adolescents with obesity do not seek medical care. Therefore, improving treatment adherence and identifying treatment barriers are necessary.

AB - Light is an attractive tool for high spatial- and contrast-resolution imaging, highly sensitive molecular imaging, and target-selective therapy, and it does not exhibit the risks associated with ionizing radiation. The main limitation of using light in clinical applications is its superficial imaging and therapeutic depth caused by high optical scattering in biological media. Here, we demonstrate that the scattering and thus defocusing of the incident light can be alleviated when simultaneously delivered ultrasound generates air bubbles in the pathway of the incident light, thus increasing the light penetration. The bubbles are temporally induced by ultrasound with an intensity that is sufficiently low to avoid tissue damage and act as a Mie scattering medium in which light is scattered predominantly in the forward direction. The change in the optical scattering property caused by the ultrasound is undone after cessation of the insonification. From the results, it is expected that this proposed method will open a new route for overcoming the limitations of current optical imaging and therapeutic techniques.

AB - Chemical doping of organic semiconductors using molecular dopants plays a key role in the fabrication of efficient organic electronic devices. Although a variety of stable molecular p-dopants have been developed and successfully deployed in devices in the past decade, air-stable molecular n-dopants suitable for materials with low electron affinity are still elusive. Here we demonstrate that photo-activation of a cleavable air-stable dimeric dopant can result in kinetically stable and efficient n-doping of host semiconductors, whose reduction potentials are beyond the thermodynamic reach of the dimer's effective reducing strength. Electron-transport layers doped in this manner are used to fabricate high-efficiency organic light-emitting diodes. Our strategy thus enables a new paradigm for using air-stable molecular dopants to improve conductivity in, and provide ohmic contacts to, organic semiconductors with very low electron affinity.

AB - The role of pathological angiogenesis on liver fibrogenesis is still unknown. Here, we developed fibrotic microniches (FMUNs) that recapitulate the interaction of liver sinusoid endothelial cells (LSECs) and hepatic stellate cells (HSCs). We investigated how the mechanical properties of their substrates affect the formation of capillary-like structures and how they relate to the progression of angiogenesis during liver fibrosis. Differences in cell response in the FMUNs were synonymous of the early and late stages of liver fibrosis. The stiffness of the early-stage FMUNs was significantly elevated due to condensation of collagen fibrils induced by angiogenesis, and led to activation of HSCs by LSECs. We utilized these FMUNs to understand the response to anti-angiogenic drugs, and it was evident that these drugs were effective only for early-stage liver fibrosis in vitro and in an in vivo mouse model of liver fibrosis. Late-stage liver fibrosis was not reversed following treatment with anti-angiogenic drugs but rather with inhibitors of collagen condensation. Our work reveals stage-specific angiogenesis-induced liver fibrogenesis via a previously unrevealed mechanotransduction mechanism which may offer precise intervention strategies targeting stage-specific disease progression. PMID- 29170556 TI - Ultrathin graphene-based membrane with precise molecular sieving and ultrafast solvent permeation. AB - Graphene oxide (GO) membranes continue to attract intense interest due to their unique molecular sieving properties combined with fast permeation. However, their use is limited to aqueous solutions because GO membranes appear impermeable to organic solvents, a phenomenon not yet fully understood. Here, we report efficient and fast filtration of organic solutions through GO laminates containing smooth two-dimensional (2D) capillaries made from large (10-20 MUm) flakes. Without modification of sieving characteristics, these membranes can be made exceptionally thin, down to ~10 nm, which translates into fast water and organic solvent permeation. We attribute organic solvent permeation and sieving properties to randomly distributed pinholes interconnected by short graphene channels with a width of 1 nm. With increasing membrane thickness, organic solvent permeation rates decay exponentially but water continues to permeate quickly, in agreement with previous reports. The potential of ultrathin GO laminates for organic solvent nanofiltration is demonstrated by showing >99.9% rejection of small molecular weight organic dyes dissolved in methanol. Our work significantly expands possibilities for the use of GO membranes in purification and filtration technologies.

AB - Biomaterials have dramatically increased in functionality and complexity, allowing unprecedented control over the cells that interact with them. From these engineering advances arises the prospect of improved biomaterial-based therapies, yet practical constraints favour simplicity. Tools from the biology community are enabling high-resolution and high-throughput bioassays that, if incorporated into a biomaterial design framework, could help achieve unprecedented functionality while minimizing the complexity of designs by identifying the most important material parameters and biological outputs. However, to avoid data explosions and to effectively match the information content of an assay with the goal of the experiment, material screens and bioassays must be arranged in specific ways. By borrowing methods to design experiments and workflows from the bioprocess engineering community, we outline a framework for the incorporation of next generation bioassays into biomaterials design to effectively optimize function while minimizing complexity. This framework can inspire biomaterials designs that maximize functionality and translatability. PMID- 29170560 TI - Clinicopathological correlation of tumor-associated macrophages in Ewing sarcoma. AB - AIMS: Tumor-associated macrophages (TAMs) are known markers playing complex roles in tumorigenesis. However, the function of TAMs in a variety of malignancies is not yet fully understood. The aim of this pilot study was to quantify the density of TAMs in Ewing sarcoma and to determine the correlation between TAMs and clinicopathological parameters. METHODS: Using immunohistochemistry, the expressions of CD68 and CD163 were examined in 24 tissue samples of Ewing sarcoma of bone. The density of CD68 and CD163-positive TAMs was analyzed quantitatively and semi-quantitatively and statistically correlated with clinical parameters. RESULTS: CD163-positive TAMs outnumbered CD68-positive cells (median of 130 vs 96, respectively). No statistically significant relatio nship was found between density of CD68-positive cells, clinical parameters or prognosis. However, high levels of CD163-positive TAMs were associated with localized disease (P=0.008). In cases with a higher density of CD163-positive cells, a trend toward longer survival was revealed (P=0.063). CONCLUSION: This is the first study that has quantified CD163 expression in TAMs in Ewing sarcoma and showed its possible prognostic value. CD163 was confirmed to be a more specific marker of macrophages than CD68. CD163 is not an exclusive hallmark of M2 macrophages.

AB - We explore the in- and out- of sample robustness of tests for choice inconsistencies based on parameter restrictions in parametric models, focusing on tests proposed by Ketcham, Kuminoff and Powers (KKP). We argue that their non parametric alternatives are inherently conservative with respect to detecting mistakes. We then show that our parametric model is robust to KKP's suggested specification checks, and that comprehensive goodness of fit measures perform better with our model than the expected utility model. Finally, we explore the robustness of our 2011 results to alternative normative assumptions highlighting the role of brand fixed effects and unobservable characteristics. PMID- 29170562 TI - Enhanced durability of carbon nanotube grafted hierarchical ceramic microfiber reinforced epoxy composites. AB - As carbon nanotube (CNT) infused hybrid composites are increasingly identified as next-generation aerospace materials, it is vital to evaluate their long-term structural performance under aging environments. In this work, the durability of hierarchical, aligned CNT grafted aluminoborosilicate microfiber-epoxy composites (CNT composites) are compared against baseline aluminoborosilicate composites (baseline composites), before and after immersion in water at 25 degrees C (hydro) and 60 degrees C (hydrothermal), for extended durations (90 d and 180 d). The addition of CNTs is found to reduce water diffusivities by approximately 1.5 times. The mechanical properties (bending strength and modulus) and the damage sensing capabilities (DC conductivity) of CNT composites remain intact regardless of exposure conditions. The baseline composites show significant loss of strength (44 %) after only 15 d of hydrothermal aging. This loss of mechanical strength is attributed to fiber-polymer interfacial debonding caused by accumulation of water at high temperatures. In situ acoustic and DC electrical measurements of hydrothermally aged CNT composites identify extensive stress relieving micro-cracking and crack deflections that are absent in the aged baseline composites. These observations are supported by SEM images of the failed composite cross-sections that highlight secondary matrix toughening mechanisms in the form of CNT pullouts and fractures which enhance the service life of composites and maintain their properties under accelerated aging environments.

AB - A full understanding and mediation of nanoparticle-serum protein interactions is key to design nanoparticles with vivid functions within the body, and to solve this problem one needs to differentiate and characterize individual nano-protein conjugates. In this paper, the authors applied capillary electrophoresis combined with inductively coupled plasma mass spectrometry detection to study the behavior of gold nanoparticles of different geometry, size and surface functionalization upon interacting with serum proteins and their mixtures. Due to high-resolution and -sensitivity benefits of this combined technique baseline separations were attained for free nanoparticles (at real-life doses) and different protein conjugates, and the conversion into the protein-bound form was scrutinized in terms of reaction time. PMID- 29170564 TI - INTEGRATED MICROFLUIDIC SELEX USING FREE SOLUTION ELECTROKINETICS. AB - Systematic evolution of ligands by exponential enrichment (SELEX) offers a powerful method to isolate affinity oligonucleotides known as aptamers, which can then be used in a wide range of applications from drug delivery to biosensing. However, conventional SELEX methods rely on labor intensive and time consuming benchtop operations. A simplified microfluidic approach is presented which allows integration of the affinity selection and amplification stages of SELEX for the isolation of target-binding oligonucleotides by combining bead-based biochemical reactions with free solution electrokinetic oligonucleotide transfer. Free solution electrokinetics allows coupling of affinity selection and amplification for closed loop oligonucleotide enrichment without the need for offline processes, flow handling components or gel components, while bead based selection and amplification allow efficient manipulation of reagents and reaction products thereby realizing on-chip loop closure and integration of the entire SELEX process. Thus the approach is capable of multi-round enrichment of oligonucleotides using simple transfer processes while maintaining a high level of device integration, as demonstrated by the isolation of an aptamer pool against a protein target (IgA) with significantly higher binding affinity than the starting library in approximately 4 hours of processing time. PMID- 29170565 TI - Behavior Problems in Elementary School among Low-Income Males: The Role of Teacher-Child Relationships. AB - The present study identified trajectories of teacher-child relationship conflict and closeness from first through sixth grades, and associations between these trajectories and externalizing and internalizing behaviors at age 11 among low income, urban males (N = 262). There were three main findings. Nagin cluster analyses indicated five trajectories for conflict with all children evidencing increases in conflict, and four trajectories for closeness with all children demonstrating decreases in closeness. Trajectories with higher levels of conflict and lower levels of closeness were associated with higher levels of externalizing and internalizing behavior problems at age 11. Moreover, conflictual teacher child relationships exacerbated the effects of externalizing and internalizing behavior problems in early childhood; children with conflictual teacher-child relationships had higher levels of behavior problems in middle childhood relative to children with low conflictual teacher-child relationships. Implications of targeting teacher-child relationships as interventions to help prevent behavior problems are discussed. PMID- 29170566 TI - What reduces sexual minority stress? A review of the intervention "toolkit". AB - Sexual orientation health disparities are rooted in sexual minorities' exposure to stress and challenges to effective coping. This paper reviews the "toolkit" of psychosocial interventions available to reduce sexual minority stress effects. A systematic search uncovered 44 interventions that both seek to reduce sexual minority stress at its source in unjust and discriminatory social structures as well as bolster sexual minorities' stigma-coping abilities. These interventions were implemented in a variety of contexts (e.g., education, health care delivery) and utilized heterogeneous modalities to create change (e.g., policy implementation, role-playing activities). They were designed to affect change across structural, interpersonal, and individual levels. The interventions reviewed here, while in early stages of efficacy testing, possess potential for meeting the needs and resources of mental and medical health care providers, policy makers, and other stakeholders who aim to lessen the burden of sexual minority stress and the health disparities it generates. PMID- 29170567 TI - Predicting ecological responses in a changing ocean: the effects of future climate uncertainty. AB - Predicting how species will respond to climate change is a growing field in marine ecology, yet knowledge of how to incorporate the uncertainty from future climate data into these predictions remains a significant challenge. To help overcome it, this review separates climate uncertainty into its three components (scenario uncertainty, model uncertainty, and internal model variability) and identifies four criteria that constitute a thorough interpretation of an ecological response to climate change in relation to these parts (awareness, access, incorporation, communication). Through a literature review, the extent to which the marine ecology community has addressed these criteria in their predictions was assessed. Despite a high awareness of climate uncertainty, articles favoured the most severe emission scenario, and only a subset of climate models were used as input into ecological analyses. In the case of sea surface temperature, these models can have projections unrepresentative against a larger ensemble mean. Moreover, 91% of studies failed to incorporate the internal variability of a climate model into results. We explored the influence that the choice of emission scenario, climate model, and model realisation can have when predicting the future distribution of the pelagic fish, Electrona antarctica. Future distributions were highly influenced by the choice of climate model, and in some cases, internal variability was important in determining the direction and severity of the distribution change. Increased clarity and availability of processed climate data would facilitate more comprehensive explorations of climate uncertainty, and increase in the quality and standard of marine prediction studies. PMID- 29170568 TI - Southern Ocean pteropods at risk from ocean warming and acidification. AB - Early life stages of marine calcifiers are particularly vulnerable to climate change. In the Southern Ocean aragonite undersaturation events and areas of rapid warming already occur and are predicted to increase in extent. Here, we present the first study to successfully hatch the polar pteropod Limacina helicina antarctica and observe the potential impact of exposure to increased temperature and aragonite undersaturation resulting from ocean acidification (OA) on the early life stage survival and shell morphology. High larval mortality (up to 39%) was observed in individuals exposed to perturbed conditions. Warming and OA induced extensive shell malformation and dissolution, respectively, increasing shell fragility. Furthermore, shell growth decreased, with variation between treatments and exposure time. Our results demonstrate that short-term exposure through passing through hotspots of OA and warming poses a serious threat to pteropod recruitment and long-term population viability. PMID- 29170569 TI - Fine-scale population genetic structure of sugar kelp, Saccharina latissima (Laminariales, Phaeophyceae), in eastern Maine, USA. AB - There is an interest to develop sugar kelp (Saccharina latissima) cultivation in the rural, eastern Maine region of the USA. Future farming efforts would benefit from an understanding of the genetic diversity and population structure of kelp, to inform management and conservation, and to identify genetic resources. The purpose of the present study was to characterize the fine-scale population genetic structure of kelp in eastern Maine, using twelve microsatellite loci. A total of 188 samples were genotyped from five sampling locations. Overall, kelp exhibited relatively low genetic diversity and small but significant differentiation among populations (FST = 0.0157). The greatest genetic difference was detected between two geographically close populations in Penobscot and Frenchman Bays, which is likely due to patterns in the Eastern Maine Coastal Current that may limit meiospore recruitment. The population structure could not be fully explained by an isolation-by-distance model. Fine-scale structuring was also detected among populations along the more continuous, eastern Maine coastline. These differences highlight that sugar kelp populations are finely structured across small spatial scales, and that future management and farming efforts should aim to maintain genetic diversity and assess the culture potential of local populations.

AB - Parental incarceration impacts millions of children in the U.S. and has important consequences for youths' adjustment. Children of incarcerated parents are at risk for a host of negative psychosocial outcomes, including substance abuse problems. Using data from a statewide survey of youth behavior, the effect of both present and past parental incarceration on youths' report of their substance use behaviors was examined. Both present and past parental incarceration was significantly associated with use of alcohol, tobacco, marijuana, and prescription drugs, as well as substance abuse and dependence. Implications for practice and research are discussed. PMID- 29170571 TI - Reliability between online raters with varying familiarities of a region: Microscale Audit of Pedestrian Streetscapes (MAPS). AB - Background: To test inter-rater reliability of the online Microscale Audit of Pedestrian Streetscapes (MAPS) tool between raters with varying familiarities of Phoenix, Arizona. Methods: The online MAPS tool, based on the MAPS in-field audit tool and scoring system, was used for audits. Sixty route pairs, 141 segment pairs, and 92 crossing pairs in Phoenix were included. Each route, segment or crossing was audited by two independent raters: one rater in Phoenix and the other in San Diego, California, respectively. Item, subscale scores, and total scores reliability analyses were computed using Kappa or intra-class correlation coefficient (ICC). Results: The route overall score had substantial reliability (ICC: 0.832). Of the route subscale and overall scores, sixteen out of twenty had moderate to substantial reliability (ICC: 0.616-0.906), and the four subscales had fair reliability (ICC: 0.409-0.563). Sixteen out of twenty scores in segment and crossing sections demonstrated fair to substantial reliability (ICC: 0.448 0.897), and the remaining four had slight reliability (ICC: 0.348-0.364). Conclusions: Most of the online MAPS items, subscales, and overall scores demonstrated fair to substantial reliability between raters with varied familiarities of the Phoenix area. Results support use of online MAPS to measure microscale elements of the built environment by raters unfamiliar with a region. PMID- 29170573 TI - Novel Pretreatments of Whole Blood Using Fenton-like Processes for Trace Metal Analysis. AB - Whole blood is a complex mixture of biological and chemical species. Its pretreatment, which is often conducted by dry ashing, is needed before the analyses of trace metals in whole blood. Recently photo-Fenton Advanced Oxidation Process (AOP) process has been used in the pretreatment of whole blood. Two new AOP processes using simple heating and microwave irradiation have been developed in the current work to pretreat blood samples. The treatments are based on a Fenton-like AOP with acid deactivation of the enzyme catalase. The first treatment is performed with a lab oven over 5 h, while the second uses microwave irradiation for 6 min. These methods allow for either cost-effective pretreatment through the use of the lab oven, or time savings through the use of the microwave oven. The degradations of blood and pure hemoglobin samples are compared through UV/visible spectroscopy, and the copper concentration in the treated samples were analyzed via anodic stripping voltammetry as a demonstration of analyzing trace metals in the pretreated whole blood. PMID- 29170572 TI - Use of Research Evidence and Implementation of Evidence-Based Practices in Youth Serving Systems. AB - Although the effectiveness of interventions for prevention and treatment of mental health and behavioral problems in abused and neglected youth is demonstrated through the accumulation of evidence through rigorous and systematic research, it is uncertain whether use of research evidence (URE) by child-serving systems leaders increases the likelihood of evidence- based practice (EBP) implementation and sustainment. Information on URE was collected from 151 directors and senior administrators of child welfare, mental health and juvenile justice systems in 40 California and 11 Ohio counties participating in an RCT of the use of community development teams (CDTs) to scale up implementation of Treatment Foster Care Oregon over a 3 year period (2010-12). Separate multivariate models were used to assess independent effects of evidence acquisition (input), evaluation (process), application (output), and URE in general (SIEU Total) on two measures of EBP implementation, highest stage reached and proportion of activities completed at pre-implementation, implementation and sustainment phases. Stage of implementation and proportion of activities completed in the implementation and sustainment phases were independently associated with acquisition of evidence and URE in general. Participation in CDTs was significantly associated with URE in general and acquisition of research evidence in particular. Implementation of EBPs for treatment of abused and neglected youth does appear to be associated with use of research evidence, especially during the later phases. PMID- 29170574 TI - The checkpoint ordering problem. AB - We suggest a new variant of a row layout problem: Find an ordering of n departments with given lengths such that the total weighted sum of their distances to a given checkpoint is minimized. The Checkpoint Ordering Problem (COP) is both of theoretical and practical interest. It has several applications and is conceptually related to some well-studied combinatorial optimization problems, namely the Single-Row Facility Layout Problem, the Linear Ordering Problem and a variant of parallel machine scheduling. In this paper we study the complexity of the (COP) and its special cases. The general version of the (COP) with an arbitrary but fixed number of checkpoints is NP-hard in the weak sense. We propose both a dynamic programming algorithm and an integer linear programming approach for the (COP) . Our computational experiments indicate that the (COP) is hard to solve in practice. While the run time of the dynamic programming algorithm strongly depends on the length of the departments, the integer linear programming approach is able to solve instances with up to 25 departments to optimality. PMID- 29170575 TI - Tower-Based Greenhouse Gas Measurement Network Design---The National Institute of Standards and Technology North East Corridor Testbed. AB - The North-East Corridor (NEC) Testbed project is the 3rd of three NIST (National Institute of Standards and Technology) greenhouse gas emissions testbeds designed to advance greenhouse gas measurements capabilities. A design approach for a dense observing network combined with atmospheric inversion methodologies is described. The Advanced Research Weather Research and Forecasting Model with the Stochastic Time-Inverted Lagrangian Transport model were used to derive the sensitivity of hypothetical observations to surface greenhouse gas emissions (footprints). Unlike other network design algorithms, an iterative selection algorithm, based on a k-means clustering method, was applied to minimize the similarities between the temporal response of each site and maximize sensitivity to the urban emissions contribution. Once a network was selected, a synthetic inversion Bayesian Kalman filter was used to evaluate observing system performance. We present the performances of various measurement network configurations consisting of differing numbers of towers and tower locations. Results show that an overly spatially compact network has decreased spatial coverage, as the spatial information added per site is then suboptimal as to cover the largest possible area, whilst networks dispersed too broadly lose capabilities of constraining flux uncertainties. In addition, we explore the possibility of using a very high density network of lower cost and performance sensors characterized by larger uncertainties and temporal drift. Analysis convergence is faster with a large number of observing locations, reducing the response time of the filter. Larger uncertainties in the observations implies lower values of uncertainty reduction. On the other hand, the drift is a bias in nature, which is added to the observations and, therefore, biasing the retrieved fluxes. PMID- 29170576 TI - Early Jurassic diversification of pycnodontiform fishes (Actinopterygii, Neopterygii) after the end-Triassic extinction event: evidence from a new genus and species, Grimmenodon aureum. AB - A new genus and species of pycnodontiform fishes, Grimmenodon aureum, from marginal marine, marine-brackish lower Toarcian (Harpoceras exaratum ammonite subzone) clay deposits of Grimmen in northeastern Germany is described. The single specimen represents a diagnostic left prearticular dentition characterized by unique tooth arrangement and ornamentation patterns. Grimmenodon aureum, gen. et sp. nov., is the second unambiguously identified pycnodontiform species from the Early Jurassic, in addition to Eomesodon liassicus from the early Lower Jurassic of western Europe. We also report an indeterminate pycnodontiform tooth crown from the upper Pliensbachian (Pleuroceras apyrenum ammonite subzone) of the same site. The material expands the Early Jurassic range of pycnodontiforms significantly northwards and confirms their presence before and immediately following the onset of the Toarcian Oceanic Anoxic Event (T-OAE) in the marginal marine ecosystems south of the Fennoscandian Shield. Moreover, the new records indicate that the Early Jurassic diversity of pycnodontiform fishes was greater than previously assumed and probably equaled that of the Late Triassic. Therefore, it is hypothesized that the Triassic-Jurassic mass extinction event did not affect pycnodontiform fishes significantly. Micro-computed tomography was used to study the internal anatomy of the prearticular of Grimmenodon aureum, gen. et sp. nov. Our results show that no replacement teeth were formed within the tooth-bearing bone but rather were added posteriorly to functional teeth. http://zoobank.org/urn:lsid:zoobank.org:pub:A56BDE9C-40C4-4CFA-9C2E-F5FA35A66F2 Citation for this article: Stumpf, S., J.

AB - The preparation and characterization of two NiII complexes are described, a terminal NiII-OH complex with the tripodal ligand tris[(N)-tertbutylureaylato)-N ethyl)]aminato ([H3buea]3-) and a terminal Ni II-OH2 complex with the tripodal ligand N,N',N"-[2,2',2"-nitrilotris(ethane-2,1-diyl)]tris(2,4,6 trimethylbenzenesulfonamido) ([MST]3-). For both complexes, the source of the -OH and -OH2 ligand is water. The salts K2[NiIIH3buea(OH)] and NMe4[NiIIMST(OH2)] were characterized using perpendicular-mode X-band electronic paramagnetic resonance, Fourier transform infrared, UV-visible spectroscopies, and its electrochemical properties were evaluated using cyclic voltammetry. The solid state structures of these complexes determined by X-ray diffraction methods reveal that they adopt a distorted trigonal bipyramidal geometry, an unusual structure for 5-coordinate NiII complexes. Moreover, the NiII-OH and NiII-OH2 units form intramolecular hydrogen bonding networks with the [H3buea]3- and [MST]3- ligands. The oxidation chemistry of these complexes was explored by treating the high-spin NiII compounds with one-electron oxidants. Species were formed with S = 1/2 spin ground states that are consistent with formation of monomeric NiIII species. While the formation of NiIII-OH complexes cannot be ruled out, the lack of observable O-H vibrations from the putative Ni-OH units suggest the possibility that other high valent Ni species are formed.

AB - Infection of the brain by the Human Immunodeficiency Virus (HIV) causes irreversible damage to the synaptic connections resulting in cognitive impairment. Patients with HIV infection, showing signs of impairment in multiple cognitive domains, as assessed by neuropsychological testing, are said to exhibit symptoms of HIV Associated Neurocognitive Disorder (HAND). In this study, we use resting-state functional MRI (fMRI) data to distinguish between healthy subjects and subjects with symptoms of HAND. To this end, we first establish a measure of interaction between pairs of regional time-series by quantifying their non-linear functional connectivity using Mutual Connectivity Analysis (MCA). Subsequently, we use a classifier to distinguish patterns of interaction between healthy and diseased individuals. Our results, quantified as the mean Area under the ROC curve (AUC) over 75 iterations, indicate that, using fMRI data, we can discriminate between the two cohorts well (AUC > 0.8). Specifically, we find that MCA (mean AUC = 0.89) based connectivity features perform significantly better (p < 0.05) when compared to cross-correlation (mean AUC = 0.82) at the classification task. A higher AUC using our approach suggests that such a nonlinear approach is better able to capture connectivity changes between brain regions and has potential for the development of novel neuro-imaging biomarkers. PMID- 29170579 TI - Predicting the Biomechanical Strength of Proximal Femur Specimens through High Dimensional Geometric Features and Support Vector Regression. AB - Estimating local trabecular bone quality for purposes of femoral bone strength prediction is important for improving the clinical assessment of osteoporotic hip fracture risk. In this study, we explore the ability of geometric features derived from the Scaling Index Method (SIM) in predicting the biomechanical strength of proximal femur specimens as visualized on multi-detector computed tomography (MDCT) images. MDCT scans were acquired for 50 proximal femur specimens harvested from human cadavers. An automated volume of interest (VOI) fitting algorithm was used to define a consistent volume in the femoral head of each specimen. In these VOIs, the non-linear micro-structure of the trabecular bone was characterized by statistical moments of its BMD distribution and by local scaling properties derived from SIM. Linear multi-regression analysis and support vector regression with a linear kernel (SVRlin) were used to predict the failure load (FL) from the feature sets; the predicted FL was compared to the FL values determined through biomechanical testing. The prediction performance was measured by the root mean square error (RMSE) for each image feature on independent test set. The best prediction result was obtained from the SIM feature set with SVRlin, which had the lowest prediction error (RMSE = 0.842 +/- 0.209) and which was significantly lower than the conventionally used mean BMD (RMSE = 1.103 +/- 0.262,, p<0.005). Our results indicate that the biomechanical strength prediction can be significantly improved in proximal femur specimens on MDCT images by using high-dimensional geometric features derived from SIM with support vector regression. PMID- 29170580 TI - Introducing Anisotropic Minkowski Functionals and Quantitative Anisotropy Measures for Local Structure Analysis in Biomedical Imaging. AB - The ability of Minkowski Functionals to characterize local structure in different biological tissue types has been demonstrated in a variety of medical image processing tasks. We introduce anisotropic Minkowski Functionals (AMFs) as a novel variant that captures the inherent anisotropy of the underlying gray-level structures. To quantify the anisotropy characterized by our approach, we further introduce a method to compute a quantitative measure motivated by a technique utilized in MR diffusion tensor imaging, namely fractional anisotropy. We showcase the applicability of our method in the research context of characterizing the local structure properties of trabecular bone micro architecture in the proximal femur as visualized on multi-detector CT. To this end, AMFs were computed locally for each pixel of ROIs extracted from the head, neck and trochanter regions. Fractional anisotropy was then used to quantify the local anisotropy of the trabecular structures found in these ROIs and to compare its distribution in different anatomical regions. Our results suggest a significantly greater concentration of anisotropic trabecular structures in the head and neck regions when compared to the trochanter region (p < 10-4 ). We also evaluated the ability of such AMFs to predict bone strength in the femoral head of proximal femur specimens obtained from 50 donors. Our results suggest that such AMFs, when used in conjunction with multi-regression models, can outperform more conventional features such as BMD in predicting failure load. We conclude that such anisotropic Minkowski Functionals can capture valuable information regarding directional attributes of local structure, which may be useful in a wide scope of biomedical imaging applications.

AB - The ability of Anisotropic Minkowski Functionals (AMFs) to capture local anisotropy while evaluating topological properties of the underlying gray-level structures has been previously demonstrated. We evaluate the ability of this approach to characterize local structure properties of trabecular bone micro architecture in ex vivo proximal femur specimens, as visualized on multi-detector CT, for purposes of biomechanical bone strength prediction. To this end, volumetric AMFs were computed locally for each voxel of volumes of interest (VOI) extracted from the femoral head of 146 specimens. The local anisotropy captured by such AMFs was quantified using a fractional anisotropy measure; the magnitude and direction of anisotropy at every pixel was stored in histograms that served as a feature vectors that characterized the VOIs. A linear multi-regression analysis algorithm was used to predict the failure load (FL) from the feature sets; the predicted FL was compared to the true FL determined through biomechanical testing. The prediction performance was measured by the root mean square error (RMSE) for each feature set. The best prediction performance was obtained from the fractional anisotropy histogram of AMF Euler Characteristic (RMSE = 1.01 +/- 0.13), which was significantly better than MDCT-derived mean BMD (RMSE = 1.12 +/- 0.16, p<0.05). We conclude that such anisotropic Minkowski Functionals can capture valuable information regarding regional trabecular bone quality and contribute to improved bone strength prediction, which is important for improving the clinical assessment of osteoporotic fracture risk. PMID- 29170582 TI - Predicting the Biomechanical Strength of Proximal Femur Specimens with Minkowski Functionals and Support Vector Regression. AB - Regional trabecular bone quality estimation for purposes of femoral bone strength prediction is important for improving the clinical assessment of osteoporotic fracture risk. In this study, we explore the ability of 3D Minkowski Functionals derived from multi-detector computed tomography (MDCT) images of proximal femur specimens in predicting their corresponding biomechanical strength. MDCT scans were acquired for 50 proximal femur specimens harvested from human cadavers. An automated volume of interest (VOI)-fitting algorithm was used to define a consistent volume in the femoral head of each specimen. In these VOIs, the trabecular bone micro-architecture was characterized by statistical moments of its BMD distribution and by topological features derived from Minkowski Functionals. A linear multi-regression analysis and a support vector regression (SVR) algorithm with a linear kernel were used to predict the failure load (FL) from the feature sets; the predicted FL was compared to the true FL determined through biomechanical testing. The prediction performance was measured by the root mean square error (RMSE) for each feature set. The best prediction result was obtained from the Minkowski Functional surface used in combination with SVR, which had the lowest prediction error (RMSE = 0.939 +/- 0.345) and which was significantly lower than mean BMD (RMSE = 1.075 +/- 0.279, p<0.005). Our results indicate that the biomechanical strength prediction can be significantly improved in proximal femur specimens with Minkowski Functionals extracted from on MDCT images used in conjunction with support vector regression.

AB - Cone beam computed tomography (CBCT) has found use in mammography for imaging the entire breast with sufficient spatial resolution at a radiation dose within the range of that of conventional mammography. Recently, enhancement of lesion tissue through the use of contrast agents has been proposed for cone beam CT. This study investigates whether the use of such contrast agents improves the ability of texture features to differentiate lesion texture from healthy tissue on CBCT in an automated manner. For this purpose, 9 lesions were annotated by an experienced radiologist on both regular and contrast-enhanced CBCT images using two dimensional (2D) square ROIs. These lesions were then segmented, and each pixel within the lesion ROI was assigned a label - lesion or non-lesion, based on the segmentation mask. On both sets of CBCT images, four three-dimensional (3D) Minkowski Functionals were used to characterize the local topology at each pixel. The resulting feature vectors were then used in a machine learning task involving support vector regression with a linear kernel (SVRlin) to classify each pixel as belonging to the lesion or non-lesion region of the ROI. Classification performance was assessed using the area under the receiver-operating characteristic (ROC) curve (AUC). Minkowski Functionals derived from contrast enhanced CBCT images were found to exhibit significantly better performance at distinguishing between lesion and non-lesion areas within the ROI when compared to those extracted from CBCT images without contrast enhancement (p < 0.05). Thus, contrast enhancement in CBCT can improve the ability of texture features to distinguish lesions from surrounding healthy tissue. PMID- 29170584 TI - Pair-wise Clustering of Large Scale Granger Causality Index Matrices for Revealing Communities. AB - The analysis of large ensembles of time series is a fundamental challenge in different domains of biomedical image processing applications, specifically in the area of functional MRI data processing. An important aspect of such analysis is the ability to reconstruct community network structures based on interactive behavior between different nodes of the network which are captured in such time series. In this study, we start with a previously proposed novel approach that applies the linear Granger Causality concept to very high-dimensional time series. This approach is based on integrating dimensionality reduction into a multivariate time series model. If residuals of dimensionality reduced models can be transformed back into the original space, prediction errors in the high dimensional space may be computed, and a large scale Granger Causality Index (lsGCI) is properly defined. The primary goal of this study was then to present an approach for recovering network structure from such lsGCI interactions through the application of pair-wise clustering. We specifically focus on a clustering approach based on topographic mapping of proximity data (TMP) for this purpose. We demonstrate our approach with a simulated network composed of five pair-wise different internal networks with varying strengths of community structure (based on the number of inter-network vertices). Our results suggest that such pair-wise clustering with TMP is capable of reconstructing the structure of the original network from lsGCI matrices that record the interactions between different nodes of the network when there is sufficient disparity between the intra- and inter network vertices. PMID- 29170585 TI - Large-Scale Granger Causality Analysis on Resting-State Functional MRI. AB - We demonstrate an approach to measure the information flow between each pair of time series in resting-state functional MRI (fMRI) data of the human brain and subsequently recover its underlying network structure. By integrating dimensionality reduction into predictive time series modeling, large-scale Granger Causality (lsGC) analysis method can reveal directed information flow suggestive of causal influence at an individual voxel level, unlike other multivariate approaches. This method quantifies the influence each voxel time series has on every other voxel time series in a multivariate sense and hence contains information about the underlying dynamics of the whole system, which can be used to reveal functionally connected networks within the brain. To identify such networks, we perform non-metric network clustering, such as accomplished by the Louvain method. We demonstrate the effectiveness of our approach to recover the motor and visual cortex from resting state human brain fMRI data and compare it with the network recovered from a visuomotor stimulation experiment, where the similarity is measured by the Dice Coefficient (DC). The best DC obtained was 0.59 implying a strong agreement between the two networks. In addition, we thoroughly study the effect of dimensionality reduction in lsGC analysis on network recovery. We conclude that our approach is capable of detecting causal influence between time series in a multivariate sense, which can be used to segment functionally connected networks in the resting-state fMRI. PMID- 29170586 TI - Investigating Changes in Brain Network Properties in HIV-Associated Neurocognitive Disease (HAND) using Mutual Connectivity Analysis (MCA). AB - About 50% of subjects infected with HIV present deficits in cognitive domains, which are known collectively as HIV associated neurocognitive disorder (HAND). The underlying synaptodendritic damage can be captured using resting state functional MRI, as has been demonstrated by a few earlier studies. Such damage may induce topological changes of brain connectivity networks. We test this hypothesis by capturing the functional interdependence of 90 brain network nodes using a Mutual Connectivity Analysis (MCA) framework with non-linear time series modeling based on Generalized Radial Basis function (GRBF) neural networks. The network nodes are selected based on the regions defined in the Automated Anatomic Labeling (AAL) atlas. Each node is represented by the average time series of the voxels of that region. The resulting networks are then characterized using graph theoretic measures that quantify various network topology properties at a global as well as at a local level. We tested for differences in these properties in network graphs obtained for 10 subjects (6 male and 4 female, 5 HIV+ and 5 HIV-). Global network properties captured some differences between these subject cohorts, though significant differences were seen only with the clustering coefficient measure. Local network properties, such as local efficiency and the degree of connections, captured significant differences in regions of the frontal lobe, precentral and cingulate cortex amongst a few others. These results suggest that our method can be used to effectively capture differences occurring in brain network connectivity properties revealed by resting-state functional MRI in neurological disease states, such as HAND. PMID- 29170587 TI - Mutual Connectivity Analysis (MCA) Using Generalized Radial Basis Function Neural Networks for Nonlinear Functional Connectivity Network Recovery in Resting-State Functional MRI. AB - We investigate the applicability of a computational framework, called mutual connectivity analysis (MCA), for directed functional connectivity analysis in both synthetic and resting-state functional MRI data. This framework comprises of first evaluating non-linear cross-predictability between every pair of time series prior to recovering the underlying network structure using community detection algorithms. We obtain the non-linear cross-prediction score between time series using Generalized Radial Basis Functions (GRBF) neural networks. These cross-prediction scores characterize the underlying functionally connected networks within the resting brain, which can be extracted using non-metric clustering approaches, such as the Louvain method. We first test our approach on synthetic models with known directional influence and network structure. Our method is able to capture the directional relationships between time series (with an area under the ROC curve = 0.92 +/- 0.037) as well as the underlying network structure (Rand index = 0.87 +/- 0.063) with high accuracy. Furthermore, we test this method for network recovery on resting-state fMRI data, where results are compared to the motor cortex network recovered from a motor stimulation sequence, resulting in a strong agreement between the two (Dice coefficient = 0.45). We conclude that our MCA approach is effective in analyzing non-linear directed functional connectivity and in revealing underlying functional network structure in complex systems. PMID- 29170588 TI - The Biophysical Effects of Neolithic Island Colonization: General Dynamics and Sociocultural Implications. AB - Does anthropogenic environmental change constrain long-term sociopolitical outcomes? It is clear that human colonization of islands radically alters their biological and physical systems. Despite considerable contextual variability in local specificities of this alteration, I argue that these processes are to some extent regular, predictable, and have socio-political implications. Reviewing the data for post-colonization ecodynamics, I show that Neolithic colonization of previously insulated habitats drives biotic homogenization. I argue that we should expect such homogenization to promote regular types of change in biophysical systems, types of change that can be described in sum as environmentally convergent. Such convergence should have significant implications for human social organization over the long term, and general dynamics of this sort are relevant in the context of understanding remarkably similar social evolutionary trajectories towards wealth-inequality not only islands, but also more generally. PMID- 29170589 TI - The Past Ubiquity and Environment of the Lost Earth Buildings of Scotland. AB - This paper investigates the once ubiquitous vernacular earth-built structures of Scotland and how perceptions of such buildings were shaped and developed through periods of intense cultural and environmental change. We focus upon the past exploitation of traditional resources to construct vernacular architectures and on changes in the perception of the resultant buildings. Historic earth-built structures are today deeply hidden within the landscapes of Scotland, although they were once a common feature of both urban and rural settlements. Whilst the eighteenth and nineteenth century period of Improvement - during which many of these structures were destroyed, repurposed, or left to decay - has received extensive attention by historians, there exists no previous serious study of the human and environmental dimensions. Through analysis of the material aspects of landscape resource use and analysis of the historical perceptions of such use, we emphasize the national significance of this undervalued aspect of Scotland's built and cultural heritage, increasingly at risk of being lost completely, highlighting the prior ubiquity of mudwall structures. PMID- 29170590 TI - People, Patches, and Parasites: The Case of Trypanosomiasis in Zimbabwe. AB - Understanding the socio-ecology of disease requires careful attention to the role of patches within disease landscapes. Such patches, and the interfaces between different socio-epidemiological systems, we argue, have important implications for disease control. We conducted an interdisciplinary study over three years to investigate the spatial dynamics of human and animal trypanosomiasis in the Zambezi valley, Zimbabwe. We used a habitat niche model to identify changes in suitable habitat for tsetse fly vectors over time, and this is related to local villagers' understandings of where flies are found. Fly trapping and blood DNA analysis of livestock highlighted the patchy distribution of both flies and trypanosome parasites. Through livelihoods analysis we explored who makes use of what areas of the landscape and when, identifying the social groups most at risk. We conclude with a discussion of the practical implications, including the need for an integrated 'One Health' approach involving targeted approaches to both vector control and surveillance. PMID- 29170591 TI - New Technological Interventions in Conservation Conflicts: Countering Emotions and Contested Knowledge. AB - New technologies have increasingly featured in environmental conservation conflicts. We examined the deployment of imaging devices such as sonar equipment and cameras to survey the Fal estuary in Cornwall, UK. Due to heavy use of these waters, there have been several disputes coalescing around protected marine features, including the estuary's rare maerl beds. A comparison of two cases, scallop dredging and docks development, showed technical instruments being deployed to produce information about the marine environment as evidence to inform decision-making. The use of imaging devices stimulated political action and was regarded as a move away from emotion-based decision-making towards desired objectivity. Simultaneously, however, the process of deploying these devices was challenged and there was recognition that the resultant information could be used to construct the estuary as a politically charged space. Thus, rather than clarifying and resolving contentious issues, technological interventions generated new baselines for knowledge contestation and amplified ongoing battles for credibility and authority. PMID- 29170592 TI - Enablers and challenges to occupational therapists' research engagement: A qualitative study. AB - Introduction: To develop occupational therapy's evidence base and improve its clinical outcomes, occupational therapists must increase their research involvement. Barriers to research consumption and leadership are well documented, but those relating to delivering research interventions, less so. Yet, interventions need to be researched within practice to demonstrate their clinical effectiveness. This study aims to improve understanding of challenges and enablers experienced by occupational therapists who deliver interventions within research programmes. Method: Twenty-eight occupational therapists who participated in the Valuing Active Life in Dementia (VALID) research programme reported their experiences in five focus groups. Data were analysed thematically to identify key and subthemes. Results: Occupational therapists reported that overwhelming paperwork, use of videos, recruitment and introducing a new intervention challenged their research involvement, whereas support, protected time and a positive attitude enabled it. The impact of these challenges and enablers varied between therapists and organisations. Conclusion: Challenges and enablers to research involvement can be identified but must be addressed within individual and organisational contexts. Multifaceted collective action to minimise challenges and maximise enablers can facilitate clinicians' involvement in research. Using this approach should enable occupational therapists to increase their research involvement, thus demonstrating the clinical effectiveness of their interventions. PMID- 29170593 TI - The use of the nest for parental roosting and thermal consequences of the nest for nestlings and parents. AB - Abstract: At temperate latitudes, altricial birds and their nestlings need to handle night temperatures well below thermoneutrality during the breeding season. Thus, energy costs of thermoregulation might constrain nestling growth, and low nocturnal temperatures might require resources that parents could otherwise have invested into nestlings during the day. To manipulate parental work rate, we performed brood size manipulations in breeding marsh tits (Poecile palustris). Nest box temperatures were always well above ambient temperature and increased with increasing brood size. In line with predictions, a large majority of females (but no males) made use of this benign environment for roosting. Furthermore, females tending enlarged broods, thereby having to work harder during the day, reduced their body temperature at night. This might have reduced nocturnal energy expenditure. Our finding that a higher proportion of enlarged, as compared to control, females continued to use the nest box as roosting sites even after a simulated predation event despite increased vulnerability to predation, further highlighting the need for energy conservation in this group. High nest box attendance and reduced body temperature in brood-reduced females may indicate that these females prioritised self-maintenance by initiating other costly physiological adjustments, e.g. moult, when relieved from parental work. We suggest that the energy demand for defending homeothermy is an element of the general trade-off between current and future reproduction, i.e. between daytime investment in food provisioning and the potential short- and long-term costs of a reduction in body temperature and increased predation risk. Significance statement: Even during summer at temperate latitudes, breeding birds need to use energy to maintain stable body temperature. Parents, thus, need to enter the night with sufficient body reserves to cover energy requirements for thermoregulation. As these resources could be used for feeding nestling during the day, adaptations to reduce the cost of thermoregulation would be selected for. We performed brood size manipulations, thereby increasing the need for nestling provisioning in marsh tits (Parus palustris). We found that females typically spent the night in the thermally benign environment of the nest box together with their brood. Females working hard during the day continued to roost in the nest box during the night despite an increase in the perceived risk of nest predation. Furthermore, these females reduced their body temperature at night, thereby reducing the gradient between ambient and body temperature, further reducing the cost of thermoregulation. PMID- 29170594 TI - Laughter and the Management of Divergent Positions in Peer Review Interactions. AB - In this paper we focus on how participants in peer review interactions use laughter as a resource as they publicly report divergence of evaluative positions, divergence that is typical in the give and take of joint grant evaluation. Using the framework of conversation analysis, we examine the infusion of laughter and multimodal laugh-relevant practices into sequences of talk in meetings of grant reviewers deliberating on the evaluation and scoring of high level scientific grant applications. We focus on a recurrent sequence in these meetings, what we call the score-reporting sequence, in which the assigned reviewers first announce the preliminary scores they have assigned to the grant. We demonstrate that such sequences are routine sites for the use of laugh practices to navigate the initial moments in which divergence of opinion is made explicit. In the context of meetings convened for the purposes of peer review, laughter thus serves as a valuable resource for managing the socially delicate but institutionally required reporting of divergence and disagreement that is endemic to meetings where these types of evaluative tasks are a focal activity. PMID- 29170595 TI - Exploring Intergenerational Continuity in Gang Membership. AB - Little is known regarding intergenerational continuity in gang membership. Qualitative literature is suggestive of intergenerational parallelism yet no known research examines the causal mechanisms associated with this cycle, if it even exists. Prospective, longitudinal data from the Rochester Youth Development Study (RYDS) and the Rochester Intergenerational Study (RIGS) assess intergenerational continuity in gang membership among 371 parent-child dyads in a series of logistic regressions accounting for moderating influences of parent sex, child sex, parent-child sex combinations, and level of contact. Path analyses reported herein explore whether parenting behaviors mediate the relationship between parent and child gang membership among fathers and mothers, respectively. Three key findings emerge. First, intergenerational continuity in gang membership exists between mothers and daughters and, conditional on contact, between fathers and sons. Second, maltreatment mediates some of this relationship among father-son dyads. Third, no pathways to daughter gang membership were identified among mothers. In sum, this study provides evidence of intergenerational continuity in gang membership and further highlights the importance of parent sex, child sex, and level of contact in intergenerational research. Future research should further explore the causal pathways between parent and child gang membership. PMID- 29170596 TI - Early-onset Conduct Problems: Predictions from daring temperament and risk taking behavior. AB - Objective: Given its considerable public health significance, identifying predictors of early expressions of conduct problems is a priority. We examined the predictive validity of daring, a key dimension of temperament, and the Balloon Analog Risk Task (BART), a laboratory-based measure of risk taking behavior, with respect to two-year change in parent, teacher-, and youth self reported oppositional defiant disorder (ODD), conduct disorder (CD), and antisocial behavior. Method: At baseline, 150 ethnically diverse 6- to 10-year old (M=7.8, SD=1.1; 69.3% male) youth with (n=82) and without (n=68) DSM-IV ADHD completed the BART whereas parents rated youth temperament (i.e., daring); parents and teachers also independently rated youth ODD and CD symptoms. Approximately 2 years later, multi-informant ratings of youth ODD, CD, and antisocial behavior were gathered from rating scales and interviews. Results: Whereas risk taking on the BART was unrelated to conduct problems, individual differences in daring prospectively predicted multi-informant rated conduct problems, independent of baseline risk taking, conduct problems, and ADHD diagnostic status. Conclusion: Early differences in the propensity to show positive socio-emotional responses to risky or novel experiences uniquely predicted escalating conduct problems in childhood, even with control of other potent clinical correlates. We consider the role of temperament in the origins and development of significant conduct problems from childhood to adolescence, including possible explanatory mechanisms underlying these predictions. PMID- 29170597 TI - The Psychometric Properties of English and Spanish Versions of the Life Orientation Test-Revised in Hispanic Americans. AB - The Life Orientation Test-Revised (LOT-R) is a widely used measure of optimism and pessimism, with three positively worded and three negatively worded content items. This study examined the structural validity and invariance, internal consistency reliability, and convergent and divergent validity of the English and Spanish versions of the LOT-R among Hispanic Americans. A community sample of Hispanic Americans (N = 422) completed self-report measures, including the LOT-R, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7, in their preferred language of English or Spanish. Based on the literature, four structural models were tested: one-factor, oblique two-factor, orthogonal two factor method effects with positive specific factor, and orthogonal two-factor method effects with negative specific factor. Baseline support for both of the English and Spanish versions was not achieved for any model; in all models, the negatively worded items in Spanish had non-significant factor loadings. Therefore, the positively worded three-item optimism subscale of the LOT-R was examined separately and fit the data, with factor loadings equivalent across language-preference groups. Coefficient alphas for the optimism subscale were consistent across both language-preference groups (alphas = .61 [English] and .66 [Spanish]). In contrast, the six-item total score and three-item pessimism subscale demonstrated extremely low or inconsistent alphas. Convergent and divergent validity were established for the optimism subscale in both languages. In sum, the optimism subscale of the LOT-R demonstrated minimally acceptable to good psychometric properties across English and Spanish language-preference groups. However, neither the total score nor the pessimism subscale showed adequate psychometric properties for Spanish-speaking Hispanic Americans, likely due to translation and cultural adaptation issues, and thus are not supported for use with this population. PMID- 29170598 TI - Experimental and Kinetic Modeling Studies on the Conversion of Sucrose to Levulinic Acid and 5-Hydroxymethylfurfural Using Sulfuric Acid in Water. AB - We here report experimental and kinetic modeling studies on the conversion of sucrose to levulinic acid (LA) and 5-hydroxymethylfurfural (HMF) in water using sulfuric acid as the catalyst. Both compounds are versatile building blocks for the synthesis of various biobased (bulk) chemicals. A total of 24 experiments were performed in a temperature window of 80-180 degrees C, a sulfuric acid concentration between 0.005 and 0.5 M, and an initial sucrose concentration between 0.05 and 0.5 M. Glucose, fructose, and HMF were detected as the intermediate products. The maximum LA yield was 61 mol %, obtained at 160 degrees C, an initial sucrose concentration of 0.05 M, and an acid concentration of 0.2 M. The maximum HMF yield (22 mol %) was found for an acid concentration of 0.05 M, an initial sucrose concentration of 0.05 M, and a temperature of 140 degrees C. The experimental data were modeled using a number of possible reaction networks. The best model was obtained when using a first order approach in substrates (except for the reversion of glucose) and agreement between experiment and model was satisfactorily. The implication of the model regarding batch optimization is also discussed.

AB - The complexity and challenges in noncontact temperature measurements inside microwave-heated catalytic reactors are presented in this paper. A custom designed microwave cavity has been used to focus the microwave field on the catalyst and enable monitoring of the temperature field in 2D. A methodology to study the temperature distribution in the catalytic bed by using a thermal camera in combination with a thermocouple for a heterogeneous catalytic reaction (methane dry reforming) under microwave heating has been demonstrated. The effects of various variables that affect the accuracy of temperature recordings are discussed in detail. The necessity of having at least one contact sensor, such as a thermocouple, or some other microwave transparent sensor, is recommended to keep track of the temperature changes occurring in the catalytic bed during the reaction under microwave heating. PMID- 29170600 TI - Production of Monosugars from Lignocellulosic Biomass in Molten Salt Hydrates: Process Design and Techno-Economic Analysis. AB - ZnCl2 hydrate, the main molten salt used in biomass conversion, combined with low concentration HCl is an excellent solvent for the dissolution and hydrolysis of the carbohydrates present in lignocellulosic biomass. The most recalcitrant carbohydrate, cellulose, is dissolved in a residence time less than 1 h under mild conditions without significant degradation. This technology is referred to as BIOeCON-solvent technology. Separation of the sugars from the solution is the main challenge. The earlier conclusion regarding the potential of zeolite beta for selective adsorption has been used as the basis of a scale-up study. The technology of choice is continuous chromatographic separation (e.g., simulated moving bed, SMB). The sugar monomers are separated from the sugar oligomers, allowing the production of monosugars at high yield, using water as an eluent. Results of a pilot plant study are presented showing a stable operation at high selectivity. Several process designs are discussed, and the techno-economic performance of the BIOeCON-solvent technology is demonstrated by comparison with the state-of-the-art technology of NREL (National Renewable Energy Laboratory), which is based on enzymatic conversion of cellulose. It is concluded that the BIOeCON-solvent technology is technically and economically viable and is competitive to the NREL process. Because the BIOeCON-solvent process is in an early stage of development and far from fully optimized, it has the potential to outperform the existing processes. PMID- 29170601 TI - Micromixing in a Rotor-Stator Spinning Disc Reactor. AB - This paper presents the micromixing times in a rotor-stator spinning disc reactor. Segregation indices are obtained at different rotational speeds performing the Villermaux-Dushman parallel-competitive reaction scheme. Consequently, the corresponding micromixing times are calculated using the engulfment model, while considering the self-engulfment effect. It was found that the segregation index decreases with an increasing disc speed. Furthermore, for the investigated operational conditions, the estimated micromixing times are in the range of 1.13 * 10-4 to 8.76 * 10-3 seconds, in agreement with the theoretical dependency on the energy dissipation rate of epsilon-0.5. In a rotor stator spinning disc reactor it is thus possible to further continue the theoretical trend of decreasing micromixing times with very high levels of energy dissipation rates that are unattainable in traditional types of process equipment. PMID- 29170602 TI - Theoretical Study of Ripening Mechanisms of Pd Clusters on Ceria. AB - We carried out density functional theory calculations to investigate the ripening of Pd clusters on CeO2(111). Starting from stable Pd n clusters (n = 1-21), we compared how these clusters can grow through Ostwald ripening and coalescence. As Pd atoms have mobility higher than that of Pd n clusters on the CeO2(111) surface, Ostwald ripening is predicted to be the dominant sintering mechanism. Particle coalescence is possible only for clusters with less than 5 Pd atoms. These ripening mechanisms are facilitated by adsorbed CO through lowering barriers for the cluster diffusion, detachment of a Pd atom from clusters, and transformation of initial planar clusters.

AB - Skiing underwent substantial changes during the post-war years when the sport turned into a multi-billion dollar industry and a leisure activity for the masses. Despite its global nature and popularity, skiing in academic writing has not gained much recognition. This paper explores the role of knowledge transfer during the pioneering phase of post-war skiing in Australia. It describes the life of Charles William Anton, an Austrian refugee from the Anschluss who migrated to Sydney and subsequently became one of the founding fathers of Australian post-war skiing. The following pages show the multi-layered nature of skiing as a global sport by exemplifying how ideas spread from pre-war Europe to post-war Australia. The paper will also provide a case study about refugee knowledge transfer and the 'productive process of absorption, adoption or rejection of knowledge' that takes place once an idea has been introduced into a new environment. PMID- 29170604 TI - Conceptual designs of conduction cooled MgB2 magnets for 1.5 and 3.0T full body MRI systems. AB - Conceptual designs of 1.5 and 3.0 T full-body magnetic resonance imaging (MRI) magnets using conduction cooled MgB2 superconductor are presented. The sizes, locations, and number of turns in the eight coil bundles are determined using optimization methods that minimize the amount of superconducting wire and produce magnetic fields with an inhomogeneity of less than 10 ppm over a 45 cm diameter spherical volume. MgB2 superconducting wire is assessed in terms of the transport, thermal, and mechanical properties for these magnet designs. Careful calculations of the normal zone propagation velocity and minimum quench energies provide support for the necessity of active quench protection instead of passive protection for medium temperature superconductors such as MgB2. A new 'active' protection scheme for medium Tc based MRI magnets is presented and simulations demonstrate that the magnet can be protected. Recent progress on persistent joints for multifilamentary MgB2 wire is presented. Finite difference calculations of the quench propagation and temperature rise during a quench conclude that active intervention is needed to reduce the temperature rise in the coil bundles and prevent damage to the superconductor. Comprehensive multiphysics and multiscale analytical and finite element analysis of the mechanical stress and strain in the MgB2 wire and epoxy for these designs are presented for the first time. From mechanical and thermal analysis of our designs we conclude there would be no damage to such a magnet during the manufacturing or operating stages, and that the magnet would survive various quench scenarios. This comprehensive set of magnet design considerations and analyses demonstrate the overall viability of 1.5 and 3.0 T MgB2 magnet designs. PMID- 29170606 TI - Religious Communities and Human Flourishing. AB - Participation in religious services is associated with numerous aspects of human flourishing, including happiness and life satisfaction, mental and physical health, meaning and purpose, character and virtue, and close social relationships. Evidence for the effects of religious communities on these flourishing outcomes now comes from rigorous longitudinal study designs with extensive confounding control. The associations with flourishing are much stronger for communal religious participation than for spiritual-religious identity or for private practices. While the social support is an important mechanism relating religion to health, this only explains a small portion of the associations. Numerous other mechanisms appear to be operative as well. It may be the confluence of the religious values and practices, reinforced by social ties and norms, that give religious communities their powerful effects on so many aspects of human flourishing.

PMID- 29170607 TI - How outpatient substance abuse treatment unit director activities may affect provision of community outreach services. AB - Aims: Community outreach services play an important role in infectious disease prevention and engaging drug users not currently in treatment. However, fewer than half of US substance abuse treatment units provide these services and many have little financial incentive to do so. Unit directors generally have latitude about scope of services, including the level of outreach provided to the community. The current study examines how directors' interactions with external stakeholders affect substance abuse treatment units' provision of community outreach services. Methods: Cross-sectional logistic and Poisson regression analyses were conducted on a national sample of US outpatient substance abuse treatment units (N = 547). Results: Findings suggest that the amount of time directors spent with licensing and monitoring associations was associated with provision of a greater number of community outreach services, while time spent with professional and occupational associations was associated with provision of off-site human immunodeficiency virus and hepatitis C testing. Several other director attributes and organizational characteristics also emerged as significant. Conclusions: External stakeholders with whom substance abuse treatment directors interact may influence community outreach through their effects on treatment directors' strategic priorities. Implications for policy and prevention efforts are discussed. PMID- 29170605 TI - Toll-Like Receptor 4 Signalling and Its Impact on Platelet Function, Thrombosis, and Haemostasis.

In addition to these classic functions, platelets have emerged as important players in the innate immune system. In particular, they interact with leukocytes, secrete pro- and anti-inflammatory factors, and express a wide range of inflammatory receptors including Toll-like receptors (TLRs), for example, Toll-like receptor 4 (TLR4). TLR4, which is the most extensively studied TLR in nucleated cells, recognises lipopolysaccharides (LPS) that are compounds of the outer surface of Gram-negative bacteria. Unlike other TLRs, TLR4 is able to signal through both the MyD88-dependent and MyD88 independent signalling pathways. Notably, despite both pathways culminating in the activation of transcription factors, TLR4 has a prominent functional impact on platelet activity, haemostasis, and thrombosis. In this review, we summarise the current knowledge on TLR4 signalling in platelets, critically discuss its impact on platelet function, and highlight the open questions in this area. PMID- 29170609 TI - New results on reachable set bounding for linear time delay systems with polytopic uncertainties via novel inequalities. AB - This work is further focused on analyzing a bound for a reachable set of linear uncertain systems with polytopic parameters. By means of L-K functional theory and novel inequalities, some new conditions which are expressed in the form of LMIs are derived. It should be noted that novel inequalities can improve upper bounds of Jensen inequalities, which yields less conservatism of systems. Consequently, some numerical examples demonstrate that the authors' results are somewhat more effective and advantageous compared with the previous results. PMID- 29170610 TI - Monotonicity, convexity, and inequalities for the generalized elliptic integrals. AB - We provide the monotonicity and convexity properties and sharp bounds for the generalized elliptic integrals [Formula: see text] and [Formula: see text] depending on a parameter [Formula: see text], which contains an earlier result in the particular case [Formula: see text]. PMID- 29170611 TI - Factors Affecting Member Perceptions of Coalition Impact. AB - The purpose of this study was to identify attributes of community-based coalitions associated with member perceptions of greater impact. Based on Hackman's model of work group effectiveness, we hypothesized that member effort, knowledge and skill, and performance strategies would affect their perceptions of coalition impact. Findings from a lagged regression on a sample of forty-five youth-oriented coalitions indicated that two aspects of member effort were associated with subsequent perceived impact, as were performance strategies for both coalition governance and community interventions. There were no associations, however, between member knowledge and skill and perceived impact. These results suggest that leaders may improve perceived coalition impact by encouraging member participation in discussions and interventions and by developing effective strategies for both governance and implementation. PMID- 29170612 TI - Visual Analytics Tools for Sustainable Lifecycle Design: Current Status, Challenges, and Future Opportunities. AB - The rapid rise in technologies for data collection has created an unmatched opportunity to advance the use of data-rich tools for lifecycle decision-making. However, the usefulness of these technologies is limited by the ability to translate lifecycle data into actionable insights for human decision-makers. This is especially true in the case of sustainable lifecycle design (SLD), as the assessment of environmental impacts, and the feasibility of making corresponding design changes, often relies on human expertise and intuition. Supporting human sense-making in SLD requires the use of both data-driven and user-driven methods while exploring lifecycle data. A promising approach for combining the two is through the use of visual analytics (VA) tools. Such tools can leverage the ability of computer-based tools to gather, process, and summarize data along with the ability of human-experts to guide analyses through domain knowledge or data driven insight. In this paper, we review previous research that has created VA tools in SLD. We also highlight existing challenges and future opportunities for such tools in different lifecycle stages-design, manufacturing, distribution & supply chain, use-phase, end-of-life, as well as life cycle assessment. Our review shows that while the number of VA tools in SLD is relatively small, researchers are increasingly focusing on the subject matter. Our review also suggests that VA tools can address existing challenges in SLD and that significant future opportunities exist.

AB - An optimization of the guanidylation process by verifying the efficacy of common guanylation reagents in order to obtain the guanidine derivatives of indolo[2,3 b]quinoline has been performed. As a result, a high-yield procedure using N,N'-di Boc-N''-triflylguanidine was applied to synthesize the guanidine derivative of indolo[2,3-b]quinoline 1 in a gram scale for specific in vitro and in vivo biological research. Extensive studies on the antiproliferative activity against eight human tumor cell lines were completed. Compound 1 revealed the highest activity against A549 lung adenocarcinoma and MCF7 breast cancer cell lines. Thus, 1 was evaluated for the in vivo anticancer activity against 4T1 mammary gland carcinoma and KLN205 murine lung carcinoma in mouse models. The anticancer effect was observed in the KLN205 model with a 37% tumor growth inhibition at the 20 mg/kg dose. This anticancer activity of 1 was comparable to that of cyclophosphamide which inhibited murine lung tumor growth in the range of 27-43% at the dose of 100 mg/kg. The biochemistry research after 1 admission, including measurements of blood parameters like alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, and urea and creatinine, were also performed. PMID- 29170614 TI - Partisan Bias in Message Selection: Media Gatekeeping of Party Press Releases. AB - Parties try to shape media coverage in ways that are favorable to them, but what determines whether media outlets pick up and report on party messages? Based on content analyses of 1,496 party press releases and 6,512 media reports from the 2013 Austrian parliamentary election campaign, we show that media coverage of individual party messages is influenced not just by news factors, but also by partisan bias. The media are therefore more likely to report on messages from parties their readers favor. Importantly, this effect is greater rather than weaker when these messages have high news value. These findings have important implications for understanding the media's role in elections and representative democracies in general.

AB - The death of a loved one, particularly a parent, has been identified as not only the most common, but also the most distressing form of adversity youth may experience in their lifetime. Surviving caregivers' communication with their children may play a critical role in shaping bereaved children's psychological functioning. However, few studies have examined the specific content (e.g., word usage) of caregivers' verbal communication as a predictor of psychological functioning in bereaved youth. In a sample of 39 parentally-bereaved children and their surviving caregivers, we investigated whether the frequency of caregivers' use of positive emotion words (e.g., "love", "happy", "hope") during a reminiscing task about the deceased was associated with children's psychological functioning and coping. In a cross-sectional analysis, we specifically examined whether these associations were moderated by the amount of time passed since children lost their parents. The Linguistic Inquiry and Word Count Program (LIWC) was used to code and evaluate the percentage of positive emotion words caregivers used during the discussion. When caregivers used more positive emotion words, children were less likely to experience depression, anxiety, and avoidant coping. Those associations were present for children who had experienced parental loss at least 105 days prior to the study. Our findings have implications for how caregivers can support their children and help to alleviate psychological distress in the aftermath of parental loss. PMID- 29170617 TI - Optimal Computing Budget Allocation for Particle Swarm Optimization in Stochastic Optimization. AB - Particle Swarm Optimization (PSO) is a popular metaheuristic for deterministic optimization. Originated in the interpretations of the movement of individuals in a bird flock or fish school, PSO introduces the concept of personal best and global best to simulate the pattern of searching for food by flocking and successfully translate the natural phenomena to the optimization of complex functions. Many real-life applications of PSO cope with stochastic problems. To solve a stochastic problem using PSO, a straightforward approach is to equally allocate computational effort among all particles and obtain the same number of samples of fitness values. This is not an efficient use of computational budget and leaves considerable room for improvement. This paper proposes a seamless integration of the concept of optimal computing budget allocation (OCBA) into PSO to improve the computational efficiency of PSO for stochastic optimization problems. We derive an asymptotically optimal allocation rule to intelligently determine the number of samples for all particles such that the PSO algorithm can efficiently select the personal best and global best when there is stochastic estimation noise in fitness values. We also propose an easy-to-implement sequential procedure. Numerical tests show that our new approach can obtain much better results using the same amount of computational effort. PMID- 29170618 TI - Bi2Se3 van der Waals Virtual Substrates for II-VI Heterostructures. AB - We report on the growth and characterization of optical quality multiple quantum well structures of Zn x Cd1-x Se/Zn x Cd y Mg1-x-y Se on an ultra-thin Bi2Se3/CdTe virtual substrate on c-plane Al2O3 (sapphire). Excellent quality highly oriented films grown along the (111) direction were achieved as evidenced by reflection high energy electron diffraction and X-ray diffraction studies. We also observed room temperature and 77 K photoluminescence emission with peak energies at 77 K of 2.407 eV and linewidths of 56 meV comparable to those achieved on structures grown on InP. Exfoliation of the structures is also possible due to the van der Waals bonding of Bi2Se3. Exfoliated (substrate free) films exhibit photoluminescence emission nearly identical to that of the supported film. Additionally, contactless electroreflectance measurements show good agreement with simulations of the multiple quantum well structure as well as evidence of excited state levels. These results open new avenues of research for substrate independent epitaxy and the possibility of ultra-thin electronics. PMID- 29170616 TI - Considering passive mechanical properties and patient user motor performance in lower limb prosthesis design optimization to enhance rehabilitation outcomes. AB - Background: Selection of prosthesis mechanical characteristics to restore function of persons with lower-limb loss can be framed as an optimization problem to satisfy a given performance objective. However, the choice of a particular objective is critical, and considering only device and generalizable outcomes across users without accounting for inherent motor performance likely restricts a given patient from fully realizing the benefits of a prosthetic intervention. Objectives: This review presents methods for optimizing passive below-knee prosthesis designs to maximize rehabilitation outcomes and how considerations on patient motor performance may enhance these outcomes. Major Findings: Available literature supports that considering patient-specific variables pertaining to motor performance permits a multidimensional landscape relating device characteristics and user function, which may yield more accurate predictions of rehabilitation outcomes for individual patients. Moreover, the addition of targeted physical therapeutic interventions that encourage user self-organization may further improve these outcomes. We note the potential of existing paradigms to address these additional dimensions, and we encourage investigators to consider the many different performance objectives available for prosthesis optimization. Conclusions: By considering user motor performance in combination with prosthesis mechanical characteristics, a staged optimization approach can be formulated which acknowledges that device modifications may only improve outcomes to a certain extent and user self-organization is a critical component to complete rehabilitation. An iterative process that can be integrated within existing rehabilitative practices accounts for changes in patient status through combined targeted prosthetic solutions and physical therapeutic techniques, and embodies the concept of personalized intervention for patients with lower limb loss. PMID- 29170619 TI - Internal and International Mobility as Adaptation to Climatic Variability in Contemporary Mexico: Evidence from the Integration of Census and Satellite Data. AB - Migration provides a strategy for rural Mexican households to cope with, or adapt to, weather events and climatic variability. Yet prior studies on "environmental migration" in this context have not examined the differences between choices of internal (domestic) or international movement. In addition, much of the prior work relied on very coarse spatial scales to operationalize the environmental variables such as rainfall patterns. To overcome these limitations, we use fine grain rainfall estimates derived from NASA's Tropical Rainfall Measuring Mission (TRMM) satellite. The rainfall estimates are combined with Population and Agricultural Census information to examine associations between environmental changes and municipal rates of internal and international migration 2005-2010. Our findings suggest that municipal-level rainfall deficits relative to historical levels are an important predictor of both international and internal migration, especially in areas dependent on seasonal rainfall for crop productivity. Although our findings do not contradict results of prior studies using coarse spatial resolution, they offer clearer results and a more spatially nuanced examination of migration as related to social and environmental vulnerability and thus higher degrees of confidence. PMID- 29170620 TI - The Coordination Abilities of Three Novel Analogues of Saliva Peptides: The Influence of Structural Modification on the Copper Binding. AB - Three novel analogues of salivary peptides as sialorphin (QHNPR) and opiorphin (QRFSR) were synthesized by the solid-phase method. The sequences of these ligands were following: AHNPR, QANPR and QRFPR. The aim of our work was investigation in what way some structural modifications may impact on coordination abilities of studied peptides. In this work we presented the interaction of pentapeptides with copper(II) ions in wide range of pH. To determine the coordination model of ligands there were carried out several studies by spectroscopy (UV-Vis, CD) methods and potentiometric measurements. PMID- 29170621 TI - The Analysis of Cu(II)/Zn(II) Cyclopeptide System as Potential Cu,ZnSOD Mimic Center. AB - In this paper are presented the features of copper (II) and zinc (II) heteronuclear complexes of the cyclic peptide-c(HKHGPG)2. The coordination properties of ligand were studied by potentiometric, UV-Vis and CD spectroscopic methods. These experiments were carried out in aqueous solutions at 298 K depending on pH. It turned out that in a physiological pH dominates Cu(II)/Zn(II) complex ([CuZnL]4+) which could mimic the active center of superoxide dismutase (Cu,ZnSOD). In next step we performed in vitro research on Cu,ZnSOD activity for [CuZnL]4+ complex existing in 7.4 pH by the method of reduction of nitroblue tetrazolium (NBT). Also mono- and di-nuclear copper (II) complexes of this ligand were examined. The ability of inhibition free radical reaction were compared for all complexes. The results of these studies show that Cu(II) mono-, di-nuclear and Cu(II)/Zn(II) complexes becoming to new promising synthetic superoxide dismutase mimetics, and should be considered for further biological assays. PMID- 29170622 TI - Comparisons of Alcohol Consumption by Time-Line Follow Back vs. Smartphone-Based Daily Interviews. AB - This study compared alcohol consumption data collected through daily interviews on a smartphone with data collected via the Timeline Follow-Back (TLFB) during a 6-week pilot study of a smartphone-based alcohol intervention system. The focus of the study was to assess for discrepancies between the two measurement methodologies on commonly utilized alcohol outcome variables. Twenty-five participants between 22 and 45 years of age and were drinking heavily at study incipience completed a 6-week alcohol intervention delivered by a smartphone application that monitored drinking through a daily interview. Participants also completed a TLFB of their alcohol consumption during the intervention period. Difference scores were calculated by subtracting the average weekly outcome variables derived from the smartphone daily interview from the average weekly outcome variables derived from the TLFB which yielded six discrepancy scores for each of the 25 participants and resulted in 150 observations. Heirarchical linear modeling indicated that the TLFB and smartphone daily interview methods did not produce significant discrepancies over the 6-week interval when examining percent of heavy drinking days and percent of days abstinent. However, discrepancies on drinks per drinking day increased substantially over time, suggesting that it is susceptible to recall bias when assessed by the TLFB. Results also indicated that participants under-reported their drinking on the TLFB compared to the daily smartphone-based assessment. Results indicate that outside of assessing for extreme drinking (binge or no drinking), the TLFB should be used cautiously and that smartphone apps represent a promising method for accurately assessing alcohol consumption over time. PMID- 29170623 TI - N2O strongly prevents adhesion formation and postoperative pain in open surgery through a drug-like effect. AB - Background: Microsurgical tenets and peritoneal conditioning during laparoscopic surgery (LS) decrease postoperative adhesions and pain. For a trial in human, the strong beneficial effects of N2O needed to be confirmed in open surgery (OS). Results: In a mouse model for OS, the effect of the gas environment upon adhesions was evaluated. Experiment I evaluated desiccation and the duration of exposure to CO2, N2O or CO2 + 4%O2. Experiment II evaluated the dose-response curve of adding N2O to CO2. Experiment III compared humidified CO2 + 10% N2O during LS and OS.In OS, 30- and 60-min exposure to non-humidified CO2 caused mortality of 33 and 100%, respectively. Mortality was prevented by humidification, by dry N2O or dry CO2 + 4%O2. Adhesions increased with the duration of exposure to CO2 (p < 0.0001) and decreased slightly by humidification or by the addition of 4% O2. N2O strongly decreased adhesions at concentrations of 5% or greater. With humidified CO2 + 10% N2O, adhesion formation was similar in OS and LS. Conclusions: The drug-like and strong beneficial effect of low concentrations of N2O is confirmed in OS. PMID- 29170624 TI - Estimating Memory Deterioration Rates Following Neurodegeneration and Traumatic Brain Injuries in a Hopfield Network Model. AB - Neurodegenerative diseases and traumatic brain injuries (TBI) are among the main causes of cognitive dysfunction in humans. At a neuronal network level, they both extensively exhibit focal axonal swellings (FAS), which in turn, compromise the information encoded in spike trains and lead to potentially severe functional deficits. There are currently no satisfactory quantitative predictors of decline in memory-encoding neuronal networks based on the impact and statistics of FAS. Some of the challenges of this translational approach include our inability to access small scale injuries with non-invasive methods, the overall complexity of neuronal pathologies, and our limited knowledge of how networks process biological signals. The purpose of this computational study is three-fold: (i) to extend Hopfield's model for associative memory to account for the effects of FAS, (ii) to calibrate FAS parameters from biophysical observations of their statistical distribution and size, and (iii) to systematically evaluate deterioration rates for different memory-recall tasks as a function of FAS injury. We calculate deterioration rates for a face-recognition task to account for highly correlated memories and also for a discrimination task of random, uncorrelated memories with a size at the capacity limit of the Hopfield network. While it is expected that the performance of any injured network should decrease with injury, our results link, for the first time, the memory recall ability to observed FAS statistics. This allows for plausible estimates of cognitive decline for different stages of brain disorders within neuronal networks, bridging experimental observations following neurodegeneration and TBI with compromised memory recall. The work lends new insights to help close the gap between theory and experiment on how biological signals are processed in damaged, high dimensional functional networks, and towards positing new diagnostic tools to measure cognitive deficits. PMID- 29170625 TI - Connectopathy in Autism Spectrum Disorders: A Review of Evidence from Visual Evoked Potentials and Diffusion Magnetic Resonance Imaging. AB - Individuals with autism spectrum disorder (ASD) show superior performance in processing fine details; however, they often exhibit impairments of gestalt face, global motion perception, and visual attention as well as core social deficits. Increasing evidence has suggested that social deficits in ASD arise from abnormal functional and structural connectivities between and within distributed cortical networks that are recruited during social information processing. Because the human visual system is characterized by a set of parallel, hierarchical, multistage network systems, we hypothesized that the altered connectivity of visual networks contributes to social cognition impairment in ASD. In the present review, we focused on studies of altered connectivity of visual and attention networks in ASD using visual evoked potentials (VEPs), event-related potentials (ERPs), and diffusion tensor imaging (DTI). A series of VEP, ERP, and DTI studies conducted in our laboratory have demonstrated complex alterations (impairment and enhancement) of visual and attention networks in ASD. Recent data have suggested that the atypical visual perception observed in ASD is caused by altered connectivity within parallel visual pathways and attention networks, thereby contributing to the impaired social communication observed in ASD. Therefore, we conclude that the underlying pathophysiological mechanism of ASD constitutes a "connectopathy." PMID- 29170626 TI - Role of MicroRNA-143 in Nerve Injury-Induced Upregulation of Dnmt3a Expression in Primary Sensory Neurons. AB - Peripheral nerve injury increased the expression of the DNA methyltransferase 3A (Dnmt3a) mRNA and its encoding Dnmt3a protein in injured dorsal root ganglia (DRG). This increase is considered as an endogenous instigator in neuropathic pain genesis through epigenetic silencing of pain-associated genes (such as Oprm1) in injured DRG. However, how DRG DNMT3a is increased following peripheral nerve injury is still elusive. We reported here that peripheral nerve injury caused by the fifth spinal nerve ligation (SNL) downregulated microRNA (miR)-143 expression in injured DRG. This downregulation was required for SNL-induced DRG Dnmt3a increase as rescuing miR-143 downregulation through microinjection of miR 143 mimics into injured DRG blocked the SNL-induced increase in Dnmt3a and restored the SNL-induced decreases in Oprm1 mRNA and its encoding mu opioid receptor (MOR) in injured DRG, impaired spinal cord central sensitization and neuropathic pain, and improved morphine analgesic effects following SNL. Mimicking SNL-induced DRG miR-143 downregulation through DRG microinjection of miR143 inhibitors in naive rats increased the expression of Dnmt3a and reduced the expression of Oprm1 mRNA and MOR in injected DRG and produced neuropathic pain-like symptoms. These findings suggest that miR-143 is a negative regulator in Dnmt3a expression in the DRG under neuropathic pain conditions and may be a potential target for therapeutic management of neuropathic pain. PMID- 29170627 TI - Combinatorial In Silico Strategy towards Identifying Potential Hotspots during Inhibition of Structurally Identical HDAC1 and HDAC2 Enzymes for Effective Chemotherapy against Neurological Disorders. AB - Histone deacetylases (HDACs) regulate epigenetic gene expression programs by modulating chromatin architecture and are required for neuronal development. Dysregulation of HDACs and aberrant chromatin acetylation homeostasis have been implicated in various diseases ranging from cancer to neurodegenerative disorders. Histone deacetylase inhibitors (HDACi), the small molecules interfering HDACs have shown enhanced acetylation of the genome and are gaining great attention as potent drugs for treating cancer and neurodegeneration. HDAC2 overexpression has implications in decreasing dendrite spine density, synaptic plasticity and in triggering neurodegenerative signaling. Pharmacological intervention against HDAC2 though promising also targets neuroprotective HDAC1 due to high sequence identity (94%) with former in catalytic domain, culminating in debilitating off-target effects and creating hindrance in the defined intervention. This emphasizes the need of designing HDAC2-selective inhibitors to overcome these vicious effects and for escalating the therapeutic efficacy. Here we report a top-down combinatorial in silico approach for identifying the structural variants that are substantial for interactions against HDAC1 and HDAC2 enzymes. We used extra-precision (XP)-molecular docking, Molecular Mechanics Generalized Born Surface Area (MMGBSA) for predicting affinity of inhibitors against the HDAC1 and HDAC2 enzymes. Importantly, we employed a novel in silico strategy of coupling the state-of-the-art molecular dynamics simulation (MDS) to energetically-optimized structure based pharmacophores (e-Pharmacophores) method via MDS trajectory clustering for hypothesizing the e-Pharmacophore models. Further, we performed e-Pharmacophores based virtual screening against phase database containing millions of compounds. We validated the data by performing the molecular docking and MM-GBSA studies for the selected hits among the retrieved ones. Our studies attributed inhibitor potency to the ability of forming multiple interactions and infirm potency to least interactions. Moreover, our studies delineated that a single HDAC inhibitor portrays differential features against HDAC1 and HDAC2 enzymes. The high affinity and selective HDAC2 inhibitors retrieved through e-Pharmacophores based virtual screening will play a critical role in ameliorating neurodegenerative signaling without hampering the neuroprotective isoform (HDAC1). PMID- 29170628 TI - Targeted Genetic Screen in Amyotrophic Lateral Sclerosis Reveals Novel Genetic Variants with Synergistic Effect on Clinical Phenotype. AB - Amyotrophic lateral sclerosis (ALS) is underpinned by an oligogenic rare variant architecture. Identified genetic variants of ALS include RNA-binding proteins containing prion-like domains (PrLDs). We hypothesized that screening genes encoding additional similar proteins will yield novel genetic causes of ALS. The most common genetic variant of ALS patients is a G4C2-repeat expansion within C9ORF72. We have shown that G4C2-repeat RNA sequesters RNA-binding proteins. A logical consequence of this is that loss-of-function mutations in G4C2-binding partners might contribute to ALS pathogenesis independently of and/or synergistically with C9ORF72 expansions. Targeted sequencing of genomic DNA encoding either RNA-binding proteins or known ALS genes (n = 274 genes) was performed in ALS patients to identify rare deleterious genetic variants and explore genotype-phenotype relationships. Genomic DNA was extracted from 103 ALS patients including 42 familial ALS patients and 61 young-onset (average age of onset 41 years) sporadic ALS patients; patients were chosen to maximize the probability of identifying genetic causes of ALS. Thirteen patients carried a G4C2-repeat expansion of C9ORF72. We identified 42 patients with rare deleterious variants; 6 patients carried more than one variant. Twelve mutations were discovered in known ALS genes which served as a validation of our strategy. Rare deleterious variants in RNA-binding proteins were significantly enriched in ALS patients compared to control frequencies (p = 5.31E-18). Nineteen patients featured at least one variant in a RNA-binding protein containing a PrLD. The number of variants per patient correlated with rate of disease progression (t test, p = 0.033). We identified eighteen patients with a single variant in a G4C2 repeat binding protein. Patients with a G4C2-binding protein variant in combination with a C9ORF72 expansion had a significantly faster disease course (t test, p = 0.025). Our data are consistent with an oligogenic model of ALS. We provide evidence for a number of entirely novel genetic variants of ALS caused by mutations in RNA-binding proteins. Moreover we show that these mutations act synergistically with each other and with C9ORF72 expansions to modify the clinical phenotype of ALS. A key finding is that this synergy is present only between functionally interacting variants. This work has significant implications for ALS therapy development. PMID- 29170629 TI - Dusp16 Deficiency Causes Congenital Obstructive Hydrocephalus and Brain Overgrowth by Expansion of the Neural Progenitor Pool. AB - Hydrocephalus can occur in children alone or in combination with other neurodevelopmental disorders that are often associated with brain overgrowth. Despite the severity of these disorders, the molecular and cellular mechanisms underlying these pathologies and their comorbidity are poorly understood. Here, we studied the consequences of genetically inactivating in mice dual-specificity phosphatase 16 (Dusp16), which is known to negatively regulate mitogen-activated protein kinases (MAPKs) and which has never previously been implicated in brain development and disorders. Mouse mutants lacking a functional Dusp16 gene (Dusp16 /-) developed fully-penetrant congenital obstructive hydrocephalus together with brain overgrowth. The midbrain aqueduct in Dusp16-/- mutants was obstructed during mid-gestation by an expansion of neural progenitors, and during later gestational stages by neurons resulting in a blockage of cerebrospinal fluid (CSF) outflow. In contrast, the roof plate and ependymal cells developed normally. We identified a delayed cell cycle exit of neural progenitors in Dusp16 /- mutants as a cause of progenitor overproliferation during mid-gestation. At later gestational stages, this expanded neural progenitor pool generated an increased number of neurons associated with enlarged brain volume. Taken together, we found that Dusp16 plays a critical role in neurogenesis by balancing neural progenitor cell proliferation and neural differentiation. Moreover our results suggest that a lack of functional Dusp16 could play a central role in the molecular mechanisms linking brain overgrowth and hydrocephalus. PMID- 29170630 TI - Heterogeneity of the Axon Initial Segment in Interneurons and Pyramidal Cells of Rodent Visual Cortex. AB - The microdomain that orchestrates action potential initiation in neurons is the axon initial segment (AIS). It has long been considered to be a rather homogeneous domain at the very proximal axon hillock with relatively stable length, particularly in cortical pyramidal cells. However, studies in other brain regions paint a different picture. In hippocampal CA1, up to 50% of axons emerge from basal dendrites. Further, in about 30% of thick-tufted layer V pyramidal neurons in rat somatosensory cortex, axons have a dendritic origin. Consequently, the AIS is separated from the soma. Recent in vitro and in vivo studies have shown that cellular excitability is a function of AIS length/position and somatodendritic morphology, undermining a potentially significant impact of AIS heterogeneity for neuronal function. We therefore investigated neocortical axon morphology and AIS composition, hypothesizing that the initial observation of seemingly homogeneous AIS is inadequate and needs to take into account neuronal cell types. Here, we biolistically transfected cortical neurons in organotypic cultures to visualize the entire neuron and classify cell types in combination with immunolabeling against AIS markers. Using confocal microscopy and morphometric analysis, we investigated axon origin, AIS position, length, diameter as well as distance to the soma. We find a substantial AIS heterogeneity in visual cortical neurons, classified into three groups: (I) axons with somatic origin with proximal AIS at the axon hillock; (II) axons with somatic origin with distal AIS, with a discernible gap between the AIS and the soma; and (III) axons with dendritic origin (axon-carrying dendrite cell, AcD cell) and an AIS either starting directly at the axon origin or more distal to that point. Pyramidal cells have significantly longer AIS than interneurons. Interneurons with vertical columnar axonal projections have significantly more distal AIS locations than all other cells with their prevailing phenotype as an AcD cell. In contrast, neurons with perisomatic terminations display most often an axon originating from the soma. Our data contribute to the emerging understanding that AIS morphology is highly variable, and potentially a function of the cell type. PMID- 29170631 TI - Histamine H3 Heteroreceptors Suppress Glutamatergic and GABAergic Synaptic Transmission in the Rat Insular Cortex. AB - Histamine H3 receptors are autoreceptors that regulate histamine release from histaminergic neuronal terminals. The cerebral cortex, including the insular cortex (IC), expresses abundant H3 receptors; however, the functions and mechanisms of H3 receptors remain unknown. The aim of this study was to elucidate the functional roles of H3 in synaptic transmission in layer V of the rat IC. Unitary excitatory and inhibitory postsynaptic currents (uEPSCs and uIPSCs) were obtained through paired whole-cell patch-clamp recording in cerebrocortical slice preparations. The H3 receptor agonist, R-alpha-methylhistamine (RAMH), reduced the uEPSC amplitude obtained from pyramidal cell to pyramidal cell or GABAergic interneuron connections. Similarly, RAMH reduced the uIPSC amplitude in GABAergic interneuron to pyramidal cell connections. RAMH-induced decreases in both the uEPSC and uIPSC amplitudes were accompanied by increases in the failure rate and paired-pulse ratio. JNJ 5207852 dihydrochloride or thioperamide, H3 receptor antagonists, inhibited RAMH-induced suppression of uEPSCs and uIPSCs. Unexpectedly, thioperamide alone increased the uIPSC amplitude, suggesting that thioperamide was likely to act as an inverse agonist. Miniature EPSC or IPSC recordings support the hypothesis that the activation of H3 receptors suppresses the release of glutamate and GABA from presynaptic terminals. The colocalization of H3 receptors and glutamate decarboxylase or vesicular glutamate transport protein 1 in presynaptic axon terminals was confirmed through double pre embedding microscopy, using a combination of pre-embedding immunogold and immunoperoxidase techniques. The suppressive regulation of H3 heteroreceptors on synaptic transmission might mediate the regulation of sensory information processes, such as gustation and visceral sensation, in the IC.

AB - The neocortex is a laminated brain structure that is the seat of higher cognitive capacity and responses, long-term memory, sensory and emotional functions, and voluntary motor behavior. Proper lamination requires that progenitor cells give rise to a neuron, that the immature neuron can migrate away from its mother cell and past other cells, and finally that the immature neuron can take its place and adopt a mature identity characterized by connectivity and gene expression; thus lamination proceeds through three steps: genesis, migration, and maturation. Each neocortical layer contains pyramidal neurons that share specific morphological and molecular characteristics that stem from their prenatal birth date. Transcription factors are dynamic proteins because of the cohort of downstream factors that they regulate. RNA-binding proteins are no less dynamic, and play important roles in every step of mRNA processing. Indeed, recent screens have uncovered post-transcriptional mechanisms as being integral regulatory mechanisms to neocortical development. Here, we summarize major aspects of neocortical laminar development, emphasizing transcriptional and post-transcriptional mechanisms, with the aim of spurring increased understanding and study of its intricacies. PMID- 29170634 TI - Lost in Time and Space: States of High Arousal Disrupt Implicit Acquisition of Spatial and Sequential Context Information. AB - Biased cognition during high arousal states is a relevant phenomenon in a variety of topics: from the development of post-traumatic stress disorders or stress triggered addictive behaviors to forensic considerations regarding crimes of passion. Recent evidence indicates that arousal modulates the engagement of a hippocampus-based "cognitive" system in favor of a striatum-based "habit" system in learning and memory, promoting a switch from flexible, contextualized to more rigid, reflexive responses. Existing findings appear inconsistent, therefore it is unclear whether and which type of context processing is disrupted by enhanced arousal. In this behavioral study, we investigated such arousal-triggered cognitive-state shifts in human subjects. We validated an arousal induction procedure (three experimental conditions: violent scene, erotic scene, neutral control scene) using pupillometry (Preliminary Experiment, n = 13) and randomly administered this method to healthy young adults to examine whether high arousal states affect performance in two core domains of contextual processing, the acquisition of spatial (spatial discrimination paradigm; Experiment 1, n = 66) and sequence information (learned irrelevance paradigm; Experiment 2, n = 84). In both paradigms, spatial location and sequences were encoded incidentally and both displacements when retrieving spatial position as well as the predictability of the target by a cue in sequence learning changed stepwise. Results showed that both implicit spatial and sequence learning were disrupted during high arousal states, regardless of valence. Compared to the control group, participants in the arousal conditions showed impaired discrimination of spatial positions and abolished learning of associative sequences. Furthermore, Bayesian analyses revealed evidence against the null models. In line with recent models of stress effects on cognition, both experiments provide evidence for decreased engagement of flexible, cognitive systems supporting encoding of context information in active cognition during acute arousal, promoting reduced sensitivity for contextual details. We argue that arousal fosters cognitive adaptation towards less demanding, more present-oriented information processing, which prioritizes a current behavioral response set at the cost of contextual cues. This transient state of behavioral perseverance might reduce reliance on context information in unpredictable environments and thus represent an adaptive response in certain situations. PMID- 29170635 TI - Interactions of Insula Subdivisions-Based Networks with Default-Mode and Central Executive Networks in Mild Cognitive Impairment. AB - Interactions between the brain networks and subnetworks are crucial for active and resting cognitive states. Whether a subnetwork can restore the adequate function of the parent network whenever a disease state affects the parent network is unclear. Investigations suggest that the control of the anterior insula-based network (AIN) over the default-mode network (DMN) and central executive network (CEN) is decreased in individuals with mild cognitive impairment (MCI). Here, we hypothesized that the posterior insula-based network (PIN) attempts to compensate for this decrease. To test this, we compared a group of MCI and normal cognitive individuals. A dynamical causal modeling method has been employed to investigate the dynamic network controls/modulations. We used the resting state functional MRI data, and assessed the interactions of the AIN and of the PIN, respectively, over the DMN and CEN. We found that the greater control of AIN than that of DMN (Wilcoxon rank sum: Z = 1.987; p = 0.047) and CEN (Z = 3.076; p = 0.002) in normal group and the lower (impaired) control of AIN than that of CEN (Z = 8.602; p = 7.816 * 10-18). We further revealed that the PIN control was significantly higher than that of DMN (Z = 6.608; p = 3.888 * 10-11) and CEN (Z = 6.429; p = 1.278 * 10-10) in MCI group where the AIN was impaired, but that control was significantly lower than of DMN (Z = 5.285; p = 1.254 * 10 7) and CEN (Z = 5.404; p = 6.513 * 10-8) in normal group. Finally, the global cognitive test score assessed using Montreal cognitive assessment and the network modulations were correlated (Spearman's correlation: r = 0.47; p = 3.76 * 10-5 and r = -0.43; p = 1.97 * 10-4). These findings might suggest the flexible functional profiles of AIN and PIN in normal aging and MCI.

AB - : Objective: To evaluate the impact of pharmacist-led warfarin management and standardized treatment protocol. Methods: A retrospective cohort study was carried out in a cardiology referral hospital located in central Kuala Lumpur, Malaysia, from 2009 to 2014. The inclusion criteria were: adult patients who were diagnosed and treated for atrial fibrillation (AF) with warfarin, attended the warfarin medication therapy adherence clinic (WMTAC) for at least 12 weeks, and with at least four international normalized ratio (INR) readings. The electronic medical records were reviewed for demographics, type of AF, warfarin dose, INRs, adverse events, co-morbidities, and drug-drug interactions. The outcome measures included the mean time to therapeutic INR, the mean percentage of time in therapeutic range (TTR), bleeding events, and common drug interactions. Results: Out of 473 patients, 151 patients fulfilled the inclusion criteria. The findings revealed that there were significant associations between the usual medical care (UMC) group and pharmacist-led WMTAC in terms of TTR (p = 0.01) and INR (p = 0.02) levels. A positive impact of pharmacists' involvement in the WMTAC clinic was where the "pharmacist's recommendation accepted" (p = 0.01) and "expanded therapeutic INR range" (p = 0.04) were statistically significantly higher in the WMTAC group. Conclusion: There was a significant positive association between the pharmacist-led WMTAC and anticoagulation effect (therapeutic TTR, INR). The identified findings revealed that expanded role of pharmacist in pharmacist managed warfarin therapy is beneficial to optimize the warfarin therapy. This study also highlighted the critical roles that pharmacists can actively play to ensure optimal anticoagulation pharmaceutical care. Key messages: What is already known on this subject?* Pharmacist-managed warfarin therapy is beneficial for optimizing warfarin therapy. In such therapy, recommendations such as dose adjustment and safer alternative drugs (given drug-drug interactions and/or food drug interactions) are made.* The active involvement of pharmacists in warfarin adherence clinics could significantly improve adherence.* However, the warfarin treatment outcomes from UMC, pharmacist-and-physician-led care and pharmacist-led care have not been studied.* The impact of the implementation of the standardized protocol for the warfarin adherence clinic has not been assessed.What this study adds?* INR levels among UMC group and WMTAC group were significantly different.* Though the TTR level for the WMTAC group was not significantly different than the UMC group, it was higher and close to the targeted 60% level.* The identified findings show that pharmacists' focus on intervention for missed doses, adherence and dose adjustment provide positive impact on patients' warfarin therapy.

AB - Executive function (EF) has been defined as a multifaceted construct that involves a variety of high-level cognitive abilities such as planning, working memory, mental flexibility, and inhibition. Being able to identify deficits in EF is important for the diagnosis and monitoring of several neurodegenerative disorders, and thus their assessment is a topic of much debate. In particular, there has been a growing interest in the development of neuropsychological screening tools that can potentially provide a reliable quick measure of EF. In this review, we critically discuss the four screening tools of EF currently available in the literature: Executive Interview-25 (EXIT 25), Frontal Assessment Battery (FAB), INECO Frontal Screening (IFS), and FRONTIER Executive Screen (FES). We first describe their features, and then evaluate their psychometric properties, the existing evidence on their neural correlates, and the empirical work that has been conducted in clinical populations. We conclude that the four screening tools generally present appropriate psychometric properties, and are sensitive to impairments in EF in several neurodegenerative conditions. However, more research will be needed mostly with respect to normative data and neural correlates, and to determine the extent to which these tools add specific information to the one provided by global cognition screening tests. More research directly comparing the available tools with each other will also be important to establish in which conditions each of them can be most useful. PMID- 29170638 TI - Volatile Oil from Amomi Fructus Attenuates 5-Fluorouracil-Induced Intestinal Mucositis. AB - Amomi Fructus has been used to treat digestive diseases in the context of traditional Chinese medicine, so we evaluated the effects of a volatile oil from Amomum villosum (VOA) on intestinal mucositis induced by 5-fluorouracil (5-FU). We measured the effect of VOA and its main active constituent, bornyl acetate (BA), on body weight, food intake, diarrhea, inflammatory cytokines, the mucosal barrier, and gut microbiota. VOA and BA significantly increased the rats' body weight, relieved diarrhea, and reversed histopathological changes in the gut and inflammation. VOA significantly inhibited apoptosis and alleviated the endoenteritis by downregulating p38 MAPK and caspase-3 expression. VOA and BA strengthened the intestinal mucosal barrier by increasing zonula occludin-1 and occludin expression. VOA and BA reduced the amount of pathogenic bacteria and increased the abundance of probiotics. Thus, VOA prevented the development and progression of intestinal mucositis after chemotherapy. PMID- 29170639 TI - A Cell Line for Detection of Botulinum Neurotoxin Type B. AB - Botulinum neurotoxins (BoNTs) type A and type B are commonly used as biopharmaceutics for neurological diseases, uniquely allowing months-long paralysis of target muscles. Their exquisite neuronal specificity is conferred by a multistep process of binding, internalization, cytosolic escape and cleavage of the neuron-specific proteins, SNAP-25 and vesicle-associated membrane proteins (VAMPs), ultimately to inhibit secretion of neurotransmitters. Currently the mouse lethality bioassay is the only available method for quality control testing of VAMP-cleaving botulinum products. Refined assays for botulinum product testing are urgently needed. Specifically, in vitro replacement assays which can account for all steps of BoNT intoxication are in high demand. Here, we describe a novel SiMa cell-based approach where re-engineering of the VAMP molecule allows detection of all BoNT/B intoxication steps using a luminescent enzymatic reaction with sensitivity comparable to mouse LD50 bioassay. The presented one-step enzyme linked immunosorbent assay meets 3Rs (replacement, reduction, and refinement of the use of animals) objectives, is user-friendly and will accelerate development of new botulinum drugs. The sensitive enzymatic reporter cell line could also be adapted for the detection of toxin activity during the manufacture of botulinum and tetanus vaccines. PMID- 29170640 TI - Shedding of Microvesicles from Microglia Contributes to the Effects Induced by Metabotropic Glutamate Receptor 5 Activation on Neuronal Death. AB - Metabotropic glutamate (mGlu) receptor 5 is involved in neuroinflammation and has been shown to mediate reduced inflammation and neurotoxicity and to modify microglia polarization. On the other hand, blockade of mGlu5 receptor results in inhibition of microglia activation. To dissect this controversy, we investigated whether microvesicles (MVs) released from microglia BV2 cells could contribute to the communication between microglia and neurons and whether this interaction was modulated by mGlu5 receptor. Activation of purinergic ionotropic P2X7 receptor with the stable ATP analog benzoyl-ATP (100 MUM) caused rapid MVs shedding from BV2 cells. Ionic currents through P2X7 receptor increased in BV2 cells pretreated for 24 h with the mGlu5 receptor agonist CHPG (200 MUM) as by patch-clamp recording. This increase was blunted when microglia cells were activated by exposure to lipopolysaccharide (LPS; 0.1 MUg/ml for 6 h). Accordingly, a greater amount of MVs formed after CHPG treatment, an effect prevented by the mGlu5 receptor antagonist MTEP (100 MUM), as measured by expression of flotillin, a membrane protein enriched in MVs. Transferred MVs were internalized by SH-SY5Y neurons where they did not modify neuronal death induced by a low concentration of rotenone (0.1 MUM for 24 h), but significantly increased rotenone neurotoxicity when shed from CHPG-treated BV2 cells. miR146a was increased in CHPG-treated MVs, an effect concealed in MVs from LPS-activated BV2 cells that showed per se an increase in miRNA146a levels. The present data support a role for microglia-shed MVs in mGlu5-mediated modulation of neuronal death and identify miRNAs as potential critical mediators of this interaction.

AB - Background: A diet rich in fat, in particular saturated fat (SF), may be linked to cardiovascular disease development, possibly due to a detrimental effect of fat on endothelial function (EF). Objective: We aimed to determine whether the habitual SF intake [as a ratio to total fat (the sum of saturated, polyunsaturated, and monounsaturated fat)] might influence endothelial function in young, overweight but otherwise healthy adults. Design: Sixty-nine young adults (49 males, mean age: 23 +/- 1 years, mean BMI: 29.1 +/- 0.8 kg/m2) were classified into three tertiles according to their habitual SF intake consumption (low SF: <39%, medium SF 39.1-43.7%, and high SF: >43.7% of total fat). Endothelial function was assessed using digital amplitude tonometry. Results: The three groups of individuals were comparable for total energy intake and calories from: fat, protein, and carbohydrates. There was no difference in anthropometric and hemodynamic variables among the groups. Those in the high SF group presented with impaired endothelial function [reactive hyperemia index (RHI): high SF: 1.60 +/- 0.08 compared to 2.23 +/- 0.16 in the medium SF and 2.12 +/- 0.14 in the low SF group, P < 0.01]. Regression analysis, including gender, age, ethnicity, body mass index indicated that the ratio of SF to total fat was an independent predictor of the RHI (P < 0.05). Conclusion: The habitual consumption of a diet high in SF in relation to polyunsaturated and monounsaturated fat was strongly associated with impaired endothelial function in young overweight adults, potentially contributing to increased risk of developing cardiovascular disease. PMID- 29170643 TI - Combining Mass Spectrometry and X-Ray Crystallography for Analyzing Native-Like Membrane Protein Lipid Complexes. AB - Membrane proteins represent a challenging family of macromolecules, particularly related to the methodology aimed at characterizing their three-dimensional structure. This is mostly due to their amphipathic nature as well as requirements of ligand bindings to stabilize or control their function. Recently, Mass Spectrometry (MS) has become an important tool to identify the overall stoichiometry of native-like membrane proteins complexed to ligand bindings as well as to provide insights into the transport mechanism across the membrane, with complementary information coming from X-ray crystallography. This perspective article emphasizes MS findings coupled with X-ray crystallography in several membrane protein lipid complexes, in particular transporters, ion channels and molecular machines, with an overview of techniques that allows a more thorough structural interpretation of the results, which can help us to unravel hidden mysteries on the membrane protein function. PMID- 29170642 TI - Muscle Non-shivering Thermogenesis and Its Role in the Evolution of Endothermy. AB - The development of sustained, long-term endothermy was one of the major transitions in the evolution of vertebrates. Thermogenesis in endotherms does not only occur via shivering or activity, but also via non-shivering thermogenesis (NST). Mammalian NST is mediated by the uncoupling protein 1 in the brown adipose tissue (BAT) and possibly involves an additional mechanism of NST in skeletal muscle. This alternative mechanism is based on Ca2+-slippage by a sarcoplasmatic reticulum Ca2+-ATPase (SERCA) and is controlled by the protein sarcolipin. The existence of muscle based NST has been discussed for a long time and is likely present in all mammals. However, its importance for thermoregulation was demonstrated only recently in mice. Interestingly, birds, which have evolved from a different reptilian lineage than mammals and lack UCP1-mediated NST, also exhibit muscle based NST under the involvement of SERCA, though likely without the participation of sarcolipin. In this review we summarize the current knowledge on muscle NST and discuss the efficiency of muscle NST and BAT in the context of the hypothesis that muscle NST could have been the earliest mechanism of heat generation during cold exposure in vertebrates that ultimately enabled the evolution of endothermy. We suggest that the evolution of BAT in addition to muscle NST was related to heterothermy being predominant among early endothermic mammals. Furthermore, we argue that, in contrast to small mammals, muscle NST is sufficient to maintain high body temperature in birds, which have enhanced capacities to fuel muscle NST by high rates of fatty acid import. PMID- 29170644 TI - An Overt Chemical Protective Garment Reduces Thermal Strain Compared with a Covert Garment in Warm-Wet but Not Hot-Dry Environments. AB - Objectives: A commercial chemical, biological, radiological and nuclear (CBRN) protective covert garment has recently been developed with the aim of reducing thermal strain. A covert CBRN protective layer can be worn under other clothing, with equipment added for full chemical protection when needed. However, it is unknown whether the covert garment offers any alleviation to thermal strain during work compared with a traditional overt ensemble. Therefore, the aim of this study was to compare thermal strain and work tolerance times during work in an overt and covert ensemble offering the same level of CBRN protection. Methods: Eleven male participants wore an overt (OVERT) or covert (COVERT) CBRN ensemble and walked (4 km.h-1, 1% grade) for a maximum of 120 min in either a wet bulb globe temperature [WBGT] of 21, 30, or 37 degrees C (Neutral, WarmWet and HotDry, respectively). The trials were ceased if the participants' gastrointestinal temperature reached 39 degrees C, heart rate reached 90% of maximum, walking time reached 120 min or due to self-termination. Results: All participants completed 120 min of walking in Neutral. Work tolerance time was greater in OVERT compared with COVERT in WarmWet (P < 0.001, 116.5[9.9] vs. 88.9[12.2] min, respectively), though this order was reversed in HotDry (P = 0.003, 37.3[5.3] vs. 48.4[4.6] min, respectively). The rate of change in mean body temperature and mean skin temperature was greater in COVERT (0.025[0.004] and 0.045[0.010] degrees C.min-1, respectively) compared with OVERT (0.014[0.004] and 0.027[0.007] degrees C.min-1, respectively) in WarmWet (P < 0.001 and P = 0.028, respectively). However, the rate of change in mean body temperature and mean skin temperature was greater in OVERT (0.068[0.010] and 0.170[0.026] degrees C.min-1, respectively) compared with COVERT (0.059[0.004] and 0.120[0.017] degrees C.min-1, respectively) in HotDry (P = 0.002 and P < 0.001, respectively). Thermal sensation, thermal comfort, and ratings of perceived exertion did not differ between garments at trial cessation (P > 0.05). Conclusion: Those dressed in OVERT experienced lower thermal strain and longer work tolerance times compared with COVERT in a warm-wet environment. However, COVERT may be an optimal choice in a hot-dry environment. These findings have practical implications for those making decisions on the choice of CBRN ensemble to be used during work. PMID- 29170646 TI - Attention-Deficit/Hyperactivity Disorder And Inflammation: What Does Current Knowledge Tell Us? A Systematic Review. AB - Background: Attention-deficit/hyperactivity disorder (ADHD) is a complex condition that interferes with development and/or functioning. Our objective is to investigate the potential association between ADHD and inflammation. Methods: We conducted a systematic review of human studies measuring inflammatory markers in ADHD. The studies were identified by searching PUBMED, MEDLINE, EMBASE, PSYCHINFO, COCHRANE, and SCOPUS databases for peer-reviewed journals published until September 2016. We included cytokine gene expression and protein measured. Fourteen papers met the inclusion criteria. Results: Seven studies evaluated the association of cytokine gene polymorphisms in ADHD, and six studies measured cytokines levels in blood. One study analyzed the presence of cytokines in cerebrospinal fluid in patients with ADHD. Altogether, these studies indicate a possible role of inflammation in ADHD pathogenesis, despite the significant heterogeneity and contradictory results. Conclusion: Evidence points to the association of ADHD with inflammatory processes, but more studies are warranted. PMID- 29170645 TI - Drugs Interfering with Muscarinic Acetylcholine Receptors and Their Effects on Place Navigation. AB - Muscarinic acetylcholine receptors (mAChRs) have been found to regulate many diverse functions, ranging from motivation and feeding to spatial navigation, an important and widely studied type of cognitive behavior. Systemic administration of non-selective antagonists of mAChRs, such as scopolamine or atropine, have been found to have adverse effects on a vast majority of place navigation tasks. However, many of these results may be potentially confounded by disruptions of functions other than spatial learning and memory. Although studies with selective antimuscarinics point to mutually opposite effects of M1 and M2 receptors, their particular contribution to spatial cognition is still poorly understood, partly due to a lack of truly selective agents. Furthermore, constitutive knock-outs do not always support results from selective antagonists. For modeling impaired spatial cognition, the scopolamine-induced amnesia model still maintains some limited validity, but there is an apparent need for more targeted approaches such as local intracerebral administration of antagonists, as well as novel techniques such as optogenetics focused on cholinergic neurons and chemogenetics aimed at cells expressing metabotropic mAChRs. PMID- 29170647 TI - Writing System Modulates the Association between Sensitivity to Acoustic Cues in Music and Reading Ability: Evidence from Chinese-English Bilingual Children. AB - Music and language share many attributes and a large body of evidence shows that sensitivity to acoustic cues in music is positively related to language development and even subsequent reading acquisition. However, such association was mainly found in alphabetic languages. What remains unclear is whether sensitivity to acoustic cues in music is associated with reading in Chinese, a morphosyllabic language. The present study aimed to answer this question by measuring music (i.e., musical metric perception and pitch discrimination), language (i.e., phonological awareness, lexical tone sensitivity), and reading abilities (i.e., word recognition) among 54 third-grade Chinese-English bilingual children. After controlling for age and non-verbal intelligence, we found that both musical metric perception and pitch discrimination accounted for unique variance of Chinese phonological awareness while pitch discrimination rather than musical metric perception predicted Chinese lexical tone sensitivity. More importantly, neither musical metric perception nor pitch discrimination was associated with Chinese reading. As for English, musical metric perception and pitch discrimination were correlated with both English phonological awareness and English reading. Furthermore, sensitivity to acoustic cues in music was associated with English reading through the mediation of English phonological awareness. The current findings indicate that the association between sensitivity to acoustic cues in music and reading may be modulated by writing systems. In Chinese, the mapping between orthography and phonology is not as transparent as in alphabetic languages such as English. Thus, this opaque mapping may alter the auditory perceptual sensitivity in music to Chinese reading. PMID- 29170648 TI - One Big Happy Family? Unraveling the Relationship between Shared Perceptions of Team Psychological Contracts, Person-Team Fit and Team Performance. AB - With the knowledge that team work is not always associated with high(er) performance, we draw from the Multi-Level Theory of Psychological Contracts, Person-Environment Fit Theory, and Optimal Distinctiveness Theory to study shared perceptions of psychological contract (PC) breach in relation to shared perceptions of complementary and supplementary fit to explain why some teams perform better than other teams. We collected three repeated survey measures in a sample of 128 respondents across 46 teams. After having made sure that we met all statistical criteria, we aggregated our focal variables to the team-level and analyzed our data by means of a longitudinal three-wave autoregressive moderated mediation model in which each relationship was one-time lag apart. We found that shared perceptions of PC breach were directly negatively related to team output and negatively related to perceived team member effectiveness through a decrease in shared perceptions of supplementary fit. However, we also demonstrated a beneficial process in that shared perceptions of PC breach were positively related to shared perceptions of complementary fit, which in turn were positively related to team output. Moreover, best team output appeared in teams that could combine high shared perceptions of complementary fit with modest to high shared perceptions of supplementary fit. Overall, our findings seem to indicate that in terms of team output there may be a bright side to perceptions of PC breach and that perceived person-team fit may play an important role in this process. PMID- 29170649 TI - Does the Effort of Processing Potential Incentives Influence the Adaption of Context Updating in Older Adults? AB - A number of aging studies suggest that older adults process positive and negative information differently. For instance, the socioemotional selectivity theory postulates that older adults preferably process positive information in service of emotional well-being (Reed and Carstensen, 2012). Moreover, recent research has started to investigate whether incentives like gains or losses can influence cognitive control in an ongoing task. In an earlier study (Schmitt et al., 2015), we examined whether incentive cues, indicating potential monetary gains, losses, or neutral outcomes for good performance in the following trial, would influence older adults' ability to exert cognitive control. Cognitive control was measured in an AX-Continuous-Performance-Task (AX-CPT) in which participants had to select their responses to probe stimuli depending on a preceding context cue. In this study, we did not find support for a positivity effect in older adults, but both gains and losses led to enhanced context processing. As the trial-wise presentation mode may be too demanding on cognitive resources for such a bias to occur, the main goal of the present study was to examine whether motivational mindsets, induced by block-wise presentation of incentives, would result in a positivity effect. For this reason, we examined 17 older participants (65-76 years) in the AX-CPT using a block-wise presentation of incentive cues and compared them to 18 older adults (69-78 years) with the trial-wise presentation mode from our earlier study (Schmitt et al., 2015). Event-related potentials were recorded to the onset of the motivational cue and during the AX-CPT. Our results show that (a) older adults initially process cues signaling potential losses more strongly, but later during the AX-CPT invest more cognitive resources in preparatory processes like context updating in conditions with potential gains, and (b) block-wise and trial-wise presentation of incentive cues differentially influenced cognitive control. When incentives were presented block-wise, the above described valence effects were consistently found. In contrast, when incentives were presented trial-wise, the effects were mixed and salience as well as valence effects can be obtained. Hence, how positive and negative incentive cues influence cognitive control in older adults is dependent on demands of cue processing. PMID- 29170650 TI - Eye Movements in Parkinson's Disease and Inherited Parkinsonian Syndromes. AB - Despite extensive research, the functions of the basal ganglia (BG) in movement control have not been fully understood. Eye movements, particularly saccades, are convenient indicators of BG function. Here, we review the main oculomotor findings reported in Parkinson's disease (PD) and genetic parkinsonian syndromes. PD is a progressive, neurodegenerative disorder caused by dopaminergic cell loss within the substantia nigra pars compacta, resulting in depletion of striatal dopamine and subsequent increased inhibitory BG output from the internal globus pallidus and the substantia nigra pars reticulata. Eye movement abnormalities are common in PD: anomalies are more evident in voluntary than reflexive saccades in the initial stages, but visually guided saccades may also be involved at later stages. Saccadic hypometria (including abnormally fragmented saccades), reduced accuracy, and increased latency are among the most prominent deficits. PD patients show also unusually frequent and large square wave jerks and impaired inhibition of reflexive saccades when voluntary mirror saccades are required. Poor convergence ability and altered pursuit are common. Inherited parkinsonisms are a heterogeneous group of rare syndromes due to gene mutations causing symptoms resembling those of PD. Eye movement characteristics of some parkinsonisms have been studied. While sharing some PD features, each syndrome has a distinctive profile that could contribute to better define the clinical phenotype of parkinsonian disorders. Moreover, because the pathogenesis and the underlying neural circuit failure of inherited parkinsonisms are often well defined, they might offer a better prospect than idiopathic PD to understand the BG function. PMID- 29170651 TI - The Spatial Associations of Cerebral Blood Flow and Spontaneous Brain Activities with White Matter Hyperintensities-An Exploratory Study Using Multimodal Magnetic Resonance Imaging. AB - White matter hyperintensities (WMHs) have been reported to be correlated with functional brain changes, but the association of the specific WMHs distribution pattern with regional functional changes remains uncertain. The aim of this study is to explore the possible spatial correlation of WMH with changes in cerebral blood flow (CBF) and spontaneous brain activities in elderly using a novel approach. The WMHs, CBF, and spontaneous brain activities measured by intrinsic connectivity contrast (ICC), were quantified using multimodal magnetic resonance imaging for 69 elderly subjects. Such approach enables us to expand our search for newly identified correlated areas by drawing strengths of different modes and provides a means for triangulation as well as complementary insights. The results showed significant positive correlations between WMH volumes in the right superior corona radiata and CBF in the left supplementary motor area, as well as between WMH volumes in left anterior limb internal capsule and CBF in the right putamen. Significant correlations of regional WMH volumes and ICC were also detected between the right anterior corona radiata and the left cuneus, and the right superior occipital cortex, as well as between the right superior corona radiata and the left superior occipital cortex. These findings may suggest a regional compensatory functional enhancement accounting for the maintenance of cognitively normal status, which can be supported by the widely observed phenomenon that mild to moderate WMH load could have little effect on global cognitive performance. PMID- 29170652 TI - Characteristic Eye Movements in Ataxia-Telangiectasia-Like Disorder: An Explanatory Hypothesis. AB - Objective: To investigate cerebellar dysfunctions and quantitatively characterize specific oculomotor changes in ataxia-telangiectasia-like disorder (ATLD), a rare autosomal recessive disease caused by mutations in the MRE11 gene. Additionally, to further elucidate the pathophysiology of cerebellar damage in the ataxia telangiectasia (AT) spectrum disorders. Methods: Saccade dynamics, metrics, and visual fixation deficits were investigated in two Italian adult siblings with genetically confirmed ATLD. Visually guided saccades were compared with those of 40 healthy subjects. Steady fixation was tested in primary and eccentric positions. Quantitative characterization of saccade parameters, saccadic intrusions (SI), and nystagmus was performed. Results: Patients showed abnormally hypermetric and fast horizontal saccades to the left and greater inaccuracy than healthy subjects in all saccadic eye movements. Eye movement abnormalities included slow eye movements that preceded the initial saccade. Horizontal and vertical spontaneous jerk nystagmus, gaze-evoked, and rebound nystagmus were evident. Fixation was interrupted by large square-wave jerk SI and macrosaccadic oscillations. Conclusion: Slow eye movements accompanying saccades, SI, and cerebellar nystagmus are frequently seen in AT patients, additionally our ATLD patients showed the presence of fast and hypermetric saccades suggesting damage of granule cell-parallel fiber-Purkinje cell synapses of the cerebellar vermis. A dual pathogenetic mechanism involving neurodevelopmental and neurodegenerative changes is hypothesized to explain the peculiar phenotype of this disease. PMID- 29170653 TI - The Association of Thyroid Disease and Oral Lichen Planus: A Literature Review and Meta-analysis. AB - Background: The objective of this study was to systemically evaluate the association between oral lichen planus (OLP) and thyroid disease. Method: Eleven electronic databases were searched for any clinical study published up until August 2016 that explored an association between OLP and thyroid disease, complemented with manual searching. The titles and abstracts of all studies identified from the electronic searches were then assessed independently to determine inclusion of the study. The population of interest was patients with OLP, and the exposure was the presence of thyroid disease in OLP patients. Statistical analyses were conducted using Review Manager 5.2. The odds ratios (OR) and 95% confidence intervals (CIs) were calculated to evaluate the association between OLP and thyroid disease. Results: Eight studies were included for review, and of these, four case-control studies were included in the final meta-analysis. The mean Newcastle-Ottawa Scale score evaluating the methodological quality of the four studies was 6.5. The OR was 2.10 (95% CI: 1.47 3.01), indicating a statistically significant difference in the prevalence of thyroid disease between the OLP and control groups. Heterogeneity was satisfactory (I2 = 0%, <25%). An approximately symmetrical funnel plot suggested no obvious publication bias. Two articles showed a higher correlation between OLP and hypothyroidism (OR 1.83, 95% CI: 1.16-2.89), with satisfactory heterogeneity (I2 = 0%, <25%). Conclusion: This meta-analysis indicated a significantly high prevalence of thyroid disease among OLP patients compared with controls, suggesting that routine screening for thyroid disease could be beneficial to OLP patients. However, due to the small number of studies included, further studies are needed to confirm the results. PMID- 29170654 TI - Preparation and Characterization of Enzyme Compartments in UV-Cured Polyurethane Based Materials and Their Application in Enzymatic Reactions. AB - The preparation and characterization of UV-cured polyurethane-based materials for the mild inclusion immobilization of enzymes was investigated. Full curing of the polymer precursor/enzyme solution mixture was realized by a short irradiation with UV-light at ambient temperatures. The included aqueous enzyme solution remains highly dispersed in the polymer material with an even size distribution throughout the polymer material. The presented concept provides stable enzyme compartments which were applied for an alcohol dehydrogenase-catalyzed reduction reaction in organic solvents. Cofactor regeneration was achieved by a substrate coupled approach via 2-propanol or an enzyme-coupled approach by a glucose dehydrogenase. This reaction concept can also be used for a simultaneous application of contrary biocatalytic reaction conditions within an enzymatic cascade reaction. Independent polymer-based reaction compartments were provided for two incompatible enzymatic reaction systems (alcohol dehydrogenase and hydroxynitrile lyase), while the relevant reactants diffuse between the applied compartments.

AB - Pathogenicity of the Gram-negative plant-pathogenic bacterium Xanthomonas campestris pv. vesicatoria depends on a type III secretion (T3S) system which translocates effector proteins into plant cells. Effector protein delivery is controlled by the T3S chaperone HpaB, which presumably escorts effector proteins to the secretion apparatus. One intensively studied effector is the transcription activator-like (TAL) effector AvrBs3, which binds to promoter sequences of plant target genes and activates plant gene expression. It was previously reported that type III-dependent delivery of AvrBs3 depends on the N-terminal protein region. The signals that control T3S and translocation of AvrBs3, however, have not yet been characterized. In the present study, we show that T3S and translocation of AvrBs3 depend on the N-terminal 10 and 50 amino acids, respectively. Furthermore, we provide experimental evidence that additional signals in the N-terminal 30 amino acids and the region between amino acids 64 and 152 promote translocation of AvrBs3 in the absence of HpaB. Unexpectedly, in vivo translocation assays revealed that AvrBs3 is delivered into plant cells even in the absence of HrpF, which is the predicted channel-forming component of the T3S translocon in the plant plasma membrane. The presence of HpaB- and HrpF-independent transport routes suggests that the delivery of AvrBs3 is initiated during early stages of the infection process, presumably before the activation of HpaB or the insertion of the translocon into the plant plasma membrane. PMID- 29170656 TI - Double-Face Meets the Bacterial World: The Opportunistic Pathogen Stenotrophomonas maltophilia. AB - Most studies on bacterial virulence focus on the pathogen itself. However, it is important to recall that the in-host behavior and the virulence of bacterial pathogens constitute a complex situation that depends on both the microorganisms and the infected host. While healthy people (the community) is infected by classical pathogenic microorganisms, able to cope with the anti-infection defenses of the host, in the case of people with basal diseases, debilitated or immunodepressed, the range of pathogens able to cause infection is wider and includes the so-named opportunistic pathogens, which lack the inherent ability to cause disease in healthy hosts and rarely produce infections in the community. Some of the most relevant opportunistic pathogens, as Stenotrophomonas maltophilia, have an environmental origin and, in occasions, present interesting biotechnological properties. Consequently, it is important knowing whether S. maltophilia isolates recovered from infections constitute a specific phylogenetic branch that has evolved toward acquiring a virulent phenotype as it happens in the case of classical pathogens or rather, any member of this bacterial species is capable of producing infection and its pathogenic behavior is mainly a consequence of the host situation. To address this question, we analyzed a set of environmental and clinical S. maltophilia strains. Our results indicate that this opportunistic pathogen presents a large core genome and that the distribution of genes in general, and of known virulence determinants in particular, is similar among environmental and clinical isolates. The majority of genes not belonging to the S. maltophilia core genome are present in just one or two of the analyzed strains. This indicates that, more than speciation into different lineages (virulent and environmental), the evolution of S. maltophilia is based in the strain-specific acquisition of genes, likely involved in the adaptation of this bacterial species to different microniches. In addition, both environmental and clinical isolates present low susceptibility to several antimicrobials. Altogether our results support that S. maltophilia does not present a specific evolutionary branch toward virulence and most likely infection is mainly the consequence of the impaired anti-infective response of the infected patients. PMID- 29170657 TI - Fitness Cost of Daptomycin-Resistant Staphylococcus aureus Obtained from in Vitro Daptomycin Selection Pressure. AB - Daptomycin-resistant (DAP-R) Staphylococcus aureus strains are well documented, but have not been reported in China. To elucidate the evolution adaptability and fitness cost of DAP-R S. aureus, three DAP susceptible strains, Pre3 (MRSA, ST239 t037), Pre5 (MRSA, ST239-t037), and Pre14b (MSSA, ST188-t189), were isolated from patients with bloodstream infections, and serially passaged in Mueller-Hinton broth with a gradient of DAP concentration to select for resistance. Highly DAP-R mutants were obtained after screening for 34 passages. The DAP minimum inhibitory concentrations increased from 0.5 MUg/ml in the parent strains to 16 MUg/ml in the mutants, which remained tolerant to 4 MUg/ml of DAP for more than 160 generations. The growth of the three mutant strains was slower than that of the parent strains, with relative fitness cost of 34.8%, 19.2%, and 15.0%, respectively. The in vitro serum tolerance of the mutants was decreased, and the lethality and pathogenicity in mice were weakened (P < 0.01). Transmission electron microscopy found that the cell walls of the mutants were significantly thicker (from 38.6% to 75.4%) than those of the parent cells. Mutation L826F of mprF was found in Post14b, G299V, and L473I of mprF and Y225N of walK were found in Post3, while T345A of mprF, S52N of graS, and F473I of walK were found in Post5. Thus, stable DAP-R mutants could be obtained from a middle-short term of in vitro DAP selection, and according to their fitness cost, some prevention and control work may be done to cope with DAP-R S. aureus that may appear in China in the future. PMID- 29170658 TI - Fungal Community Structure and As-Resistant Fungi in a Decommissioned Gold Mine Site. AB - Although large quantities of heavy metal laden wastes are released in an uncontrolled manner by gold mining activities with ensuing contamination of the surrounding areas, there is scant information on the mycobiota of gold-mine sites. Thus, the present study was aimed to describe the fungal community structure in three differently As- and Hg-polluted soils collected from the Pestarena decommissioned site by using Illumina(r) metabarcoding. Fungal richness was found to increase as the contamination level increased while biodiversity was not related to the concentrations of inorganic toxicants. Within the phylum Zygomigota which, irrespective of the contamination level, was predominant in all the soils under study, the most abundant genera were Mucor and Mortierella. The relative abundances of Basidiomycota, instead, tended to raise as the contamination increased; within this phylum the most abundant genera were Cryptococcus and Pseudotomentella. The abundance of Ascomycota, ranging from about 8 to 21%, was not related to the contamination level. The relative abundances of those genera (i.e., Penicillium, Trichoderma, and Chaetomium), the cultivable isolates of which exhibited significant As-resistance, were lower than the set threshold (0.5%). Mass balances obtained from As-exposure experiments with these isolates showed that the main mechanisms involved in counteracting the toxicant were accumulation and, above all, volatilization, the respective extents of which ranged from 0.6 to 5.9% and from 6.4 to 31.2% in dependence of the isolate. PMID- 29170659 TI - Geochemical Influence on Microbial Communities at CO2-Leakage Analog Sites. AB - Microorganisms influence the chemical and physical properties of subsurface environments and thus represent an important control on the fate and environmental impact of CO2 that leaks into aquifers from deep storage reservoirs. How leakage will influence microbial populations over long time scales is largely unknown. This study uses natural analog sites to investigate the long-term impact of CO2 leakage from underground storage sites on subsurface biogeochemistry. We considered two sites with elevated CO2 levels (sample groups I and II) and one control site with low CO2 content (group III). Samples from sites with elevated CO2 had pH ranging from 6.2 to 4.5 and samples from the low CO2 control group had pH ranging from 7.3 to 6.2. Solute concentrations were relatively low for samples from the control group and group I but high for samples from group II, reflecting varying degrees of water-rock interaction. Microbial communities were analyzed through clone library and MiSeq sequencing. Each 16S rRNA analysis identified various bacteria, methane-producing archaea, and ammonia-oxidizing archaea. Both bacterial and archaeal diversities were low in groundwater with high CO2 content and community compositions between the groups were also clearly different. In group II samples, sequences classified in groups capable of methanogenesis, metal reduction, and nitrate reduction had higher relative abundance in samples with relative high methane, iron, and manganese concentrations and low nitrate levels. Sequences close to Comamonadaceae were abundant in group I, while the taxa related to methanogens, Nitrospirae, and Anaerolineaceae were predominant in group II. Our findings provide insight into subsurface biogeochemical reactions that influence the carbon budget of the system including carbon fixation, carbon trapping, and CO2 conversion to methane. The results also suggest that monitoring groundwater microbial community can be a potential tool for tracking CO2 leakage from geologic storage sites. PMID- 29170660 TI - Effect of Dietary Forage to Concentrate Ratios on Dynamic Profile Changes and Interactions of Ruminal Microbiota and Metabolites in Holstein Heifers. AB - A better understanding of global ruminal microbiota and metabolites under extensive feeding conditions is a prerequisite for optimizing rumen function and improving ruminant feed efficiency. Furthermore, the gap between the information on the ruminal microbiota and metabolites needs to be bridged. The aim of this study was to investigate the effects of a wide range of forage to concentrate ratios (F:C) on changes and interactions of ruminal microbiota and metabolites. Four diets with different F:C (80:20, 60:40, 40:60, and 20:80) were limit-fed to 24 Holstein heifers, and Illumina MiSeq sequencing and gas chromatography time-of flight/mass spectrometry were used to investigate the profile changes of the ruminal microbes and metabolites, and the interaction between them. The predominant bacterial phyla in the rumen were Bacteroidetes (57.2 +/- 2.6%) and Firmicutes (26.8 +/- 1.6%), and the predominant anaerobic fungi were Neocallimastigomycota (64.3 +/- 3.8%) and Ascomycota (22.6 +/- 2.4%). In total, 44, 9, 25, and 2 genera, respectively, were identified as the core rumen bacteria, ciliate protozoa, anaerobic fungi, and archaea communities across all samples. An increased concentrate level linearly decreased the relative abundance of cellulolytic bacteria and ciliates, namely Fibrobacter, Succinimonas, Polyplastron, and Ostracodinium (q < 0.05), and linearly increased the relative abundance of Entodinium (q = 0.04), which is a non-fibrous carbohydrate degrader. Dietary F:C had no effect on the communities of anaerobic fungi and archaea. Rumen metabolomics analysis revealed that ruminal amino acids, lipids, organic acids, and carbohydrates were altered significantly by altering the dietary F:C. With increasing dietary concentrate levels, the proportions of propionate and butyrate linearly increased in the rumen (P <= 0.01). Correlation analysis revealed that there was some utilization relationship or productive association between candidate metabolites and affected microbe groups. This study provides a better understanding of ruminal microbiota and metabolites under a wide range of dietary F:C, which could further reveal integrative information of rumen function and lead to an improvement in ruminant production. PMID- 29170661 TI - Trade, Diplomacy, and Warfare: The Quest for Elite Rhizobia Inoculant Strains. AB - Rhizobia form symbiotic nitrogen-fixing nodules on leguminous plants, which provides an important source of fixed nitrogen input into the soil ecosystem. The improvement of symbiotic nitrogen fixation is one of the main challenges facing agriculture research. Doing so will reduce the usage of chemical nitrogen fertilizer, contributing to the development of sustainable agriculture practices to deal with the increasing global human population. Sociomicrobiological studies of rhizobia have become a model for the study of the evolution of mutualistic interactions. The exploitation of the wide range of social interactions rhizobia establish among themselves, with the soil and root microbiota, and with the host plant, could constitute a great advantage in the development of a new generation of highly effective rhizobia inoculants. Here, we provide a brief overview of the current knowledge on three main aspects of rhizobia interaction: trade of fixed nitrogen with the plant; diplomacy in terms of communication and possible synergistic effects; and warfare, as antagonism and plant control over symbiosis. Then, we propose new areas of investigation and the selection of strains based on the combination of the genetic determinants for the relevant rhizobia symbiotic behavioral phenotypes. PMID- 29170662 TI - Salmonella in Peripheral Lymph Nodes of Healthy Cattle at Slaughter. AB - To more fully characterize the burden of Salmonella enterica in bovine peripheral lymph nodes (PLN), PLN (n = 5,450) were collected from healthy cattle at slaughter in 12 commercial abattoirs that slaughtered feedlot-fattened (FF) cattle exclusively (n = 7), cattle removed (or culled) from breeding herds (n = 3), or both FF and cull cattle (n = 2). Qualitative and quantitative methods were used to estimate prevalence and concentration of Salmonella in PLN. Isolates were subjected to a variety of phenotypic, serological, and molecular assays. Overall, Salmonella prevalence in PLN from FF and cull cattle was 7.1 and 1.8%. However, burden varied by season in that observed prevalence in PLN collected in cooler or warmer seasons was 2.4 and 8.2%, respectively. Prevalence in PLN from cull cattle in the southwest region of the US was 2.1 and 1.1% for cool and warm seasons, respectively; however, prevalence in FF PLN was far greater in that it was 6.5 and 31.1%, respectively. Salmonella was recovered from 289 (5.6%) PLN and 2.9% (n = 160) of all PLN tested had quantifiable concentrations that varied from 1.6 to 4.9 log10 colony forming units/PLN. The most common serotypes isolated from PLN were Montevideo (26.9%), Lille (14.9%), Cerro (13.0%), Anatum (12.8%), and Dublin (6.9%). In all, 376 unique isolates were collected from the 289 Salmonella positive PLN. Antimicrobial susceptibility testing revealed the majority (80.6%) of these isolates were pansusceptible; however, 10.7% of isolates were found to be resistant to two or more antimicrobial classes. We were able to document an observed increased in prevalence of Salmonella in PLN during the warmer season, particularly in FF cattle from the southwest region of the US. The mechanisms underlying the observed association between season, region, and production source have yet to be elucidated. Nevertheless, these findings increase our understanding of the sources of contamination of beef products and shed light on transmission dynamics that may be useful in targeting these sources. PMID- 29170663 TI - Neutrophil Functional Heterogeneity: Identification of Competitive Phagocytosis. AB - Introduction: Phagocytosis by neutrophils is a key process in the innate immune response against invading microorganisms. Despite reported heterogeneity in other neutrophils functions, little is known regarding differences in phagocytosis by individual cells. Therefore, we tested the hypothesis that heterogeneity is present in the neutrophil compartment in its potency to phagocytize bacteria. Methods: Phagocytosis assays were performed in suspension with isolated neutrophils and Staphylococcus aureus expressing different fluorescent proteins at MOIs between 1 and 10. Repetitive addition of bacteria with different fluorescent proteins and MOIs was used to compare the phagocytic capacity of S. aureus-green fluorescent protein (GFP)-positive and negative neutrophils and exclude randomness. Results: The percentage and mean fluorescence intensity (MFI) of S. aureus-GFP-positive neutrophils increased with higher MOIs. The increase in MFI was due to phagocytosis of multiple bacteria per neutrophil as was confirmed by confocal imaging. Sequential phagocytosis of GFP- and mCherry-expressing S. aureus showed a non-random process, as S. aureus-GFP-positive neutrophils preferentially phagocytized S. aureus-mCherry. Conclusion: All neutrophils were able to phagocytize S. aureus, but some were much more potent than others. Therefore, at physiologically relevant MOIs these potent phagocytizing neutrophils will outcompete the uptake of bacteria by less competent cells in a process we propose to name "competitive phagocytosis." PMID- 29170664 TI - The Intra-Dependence of Viruses and the Holobiont. AB - Animals live in symbiosis with the microorganisms surrounding them. This symbiosis is necessary for animal health, as a symbiotic breakdown can lead to a disease state. The functional symbiosis between the host, and associated prokaryotes, eukaryotes, and viruses in the context of an environment is the holobiont. Deciphering these holobiont associations has proven to be both difficult and controversial. In particular, holobiont association with viruses has been of debate even though these interactions have been occurring since cellular life began. The controversy stems from the idea that all viruses are parasitic, yet their associations can also be beneficial. To determine viral involvement within the holobiont, it is necessary to identify and elucidate the function of viral populations in symbiosis with the host. Viral metagenome analyses identify the communities of eukaryotic and prokaryotic viruses that functionally associate within a holobiont. Similarly, analyses of the host in response to viral presence determine how these interactions are maintained. Combined analyses reveal how viruses interact within the holobiont and how viral symbiotic cooperation occurs. To understand how the holobiont serves as a functional unit, one must consider viruses as an integral part of disease, development, and evolution. PMID- 29170665 TI - Canonical Stimulation of the NLRP3 Inflammasome by Fungal Antigens Links Innate and Adaptive B-Lymphocyte Responses by Modulating IL-1beta and IgM Production. AB - The NLRP3 inflammasome is activated in response to different bacterial, viral, and fungal pathogens and serves as modulator of different pattern recognition receptors signaling pathways. One of the main functions of NLRP3 is to participate in IL-1beta maturation which is important in the host defense against Pneumocystis and other fungal infections. However, dysregulation of NLRP3 and IL 1beta secretion are also implicated in the pathophysiology of many auto inflammatory disorders. Often time's inflammatory flares are preceded by infectious illnesses questioning the role of infection in autoimmune exacerbations. However, we still do not fully understand the exact role that infection or even colonization plays as a trigger of inflammation. Herein, we investigated the role of NLRP3 in circulating B-lymphocytes following activation with two major microbial antigens (beta-glucan and CpG). NLRP3 was determined essential in two independent B-lymphocytes processes: pro-inflammatory cytokine secretion and antibody regulation. Our results show that the beta-glucan fungal cell wall carbohydrate stimulated B-lymphocytes to secrete IL-1beta in a process partially mediated by Dectin-1 activation via SYK and the transcription factors NF-kappaB and AP-1. This IL-1beta secretion was regulated by the NLRP3 inflammasome and was dependent on potassium efflux and Caspase-1. Interestingly, B-lymphocytes activated by unmethylated CpG motifs, found in bacterial and fungal DNA, failed to induce IL-1beta. However, B-lymphocyte stimulation by CpG resulted in NLRP3 and Caspase-1 activation and the production and secretion of IgM antibodies. Furthermore, CpG-stimulated IgM secretion, unlike beta-glucan mediated IL-1beta production, was mediated by the mammalian target of rapamycin (mTOR). Inhibition of NLRP3 and the mTOR pathway in CpG activated B-lymphocytes resulted in impaired IgM secretion suggesting their participation in antibody regulation. In conclusion, this study describes a differential response of NLRP3 to beta-glucan and CpG antigens and identifies the NLRP3 inflammasome of human circulating B-lymphocytes as a modulator of the innate and adaptive immune systems. PMID- 29170666 TI - Low T-Cell Responses to Mitogen Stimulation Predicts Poor Survival in Recipients of Allogeneic Hematopoietic Stem Cell Transplantation. AB - Background: Successful engraftment and reconstitution of the innate and adaptive immune system are associated with improved outcomes in recipients of allogeneic hematopoietic stem cell transplantation (HSCT). A clinically meaningful and simple biomarker of immunosuppression could potentially assist clinicians in their decision-making. We aimed to determine the relationship between T-cell production of interferon gamma (IFN-gamma) in response to phytohemagglutinin (PHA) to clinical outcomes in HSCT recipients. Methods: A prospective observational multicenter study of 73 adult allogeneic HSCT recipients was conducted in Melbourne, Australia. Eligible participants were >18 years and at risk of cytomegalovirus disease. T-cell responses to PHA were assessed at 3, 6, 9, and 12 months post-HSCT using the commercial quantiferon-cytomegalovirus assay, which quantifies IFN-gamma production by ELISA following stimulation with PHA. A low response was defined as IFN-gamma <0.5 IU/ml following stimulation with PHA. Results: At 3 months post-HSCT, high responses to PHA (median IFN-gamma 7.68 IU/ml) were seen in 63% of participants and low responses to PHA (median IFN gamma 0.06 IU/ml) in 37%. IFN-gamma responses to PHA were significantly associated with the severity of acute graft versus host disease (AGVHD) (spearman r = -0.53, p < 0.001) and correlated with blood lymphocyte count (spearman r = 0.52, p < 0.001). Twelve month overall survival was greater in individuals with high compared to low IFN-gamma response to PHA at 3 months [92 vs. 62%, respectively, Cox proportional hazard ratio (HR): 4.12 95% CI: 1.2-13.7, p = 0.02]. Non-relapse mortality (NRM) was higher in individuals with low IFN-gamma response to PHA (competing risk regression HR 11.6 p = 0.02). In individuals with no AGVHD compared to AGVHD and high IFN-gamma response to PHA compared to AGVHD and low IFN-gamma response to PHA, 12-month survival was 100 vs. 80 vs. 52%, respectively (log rank test p < 0.0001). Conclusion: Low IFN-gamma response to PHA at the 3-month time-point following allogeneic HSCT was predictive of reduced 12-month overall survival, increased NRM, and reduced survival in recipients with AGVHD. Assessing IFN-gamma response to PHA post-HSCT may be a clinically useful immune biomarker. PMID- 29170667 TI - Will a mAb-Based Immunotherapy Directed against Cancer Stem Cells Be Feasible? AB - The cancer stem cell (CSC) hypothesis suggests that within a tumor, there is a small subpopulation of cells with stem cell properties responsible for tumor maintenance and metastasis generation. This hypothesis also implies that new antitumor drugs, rather than targeting the bulk of the tumor mass, would be more effective if they directly targeted the CSC subpopulation. The CSCs from several types of tumors have been identified with mAbs recognizing surface antigens in these cells; however, antigens specifically or exclusively expressed in the CSC population have not yet been identified. Thus, questioning the possibility of using therapeutic antibodies directed against the CSCs. Here, we review the possibilities of using antibodies directly targeting the CSCs as therapeutic agents in the form of naked antibodies, antibodies conjugated to nanoparticles, or antibody cocktails. PMID- 29170668 TI - Epitope-Specific Tolerance Modes Differentially Specify Susceptibility to Proteolipid Protein-Induced Experimental Autoimmune Encephalomyelitis. AB - Immunization with myelin components can elicit experimental autoimmune encephalomyelitis (EAE). EAE susceptibility varies between mouse strains, depending on the antigen employed. BL/6 mice are largely resistant to EAE induction with proteolipid protein (PLP), probably a reflection of antigen specific tolerance. However, the extent and mechanism(s) of tolerance to PLP remain unclear. Here, we identified three PLP epitopes in PLP-deficient BL/6 mice. PLP-sufficient mice did not respond against two of these, whereas tolerance was "leaky" for an epitope with weak predicted MHCII binding, and only this epitope was encephalitogenic. In TCR transgenic mice, the "EAE-susceptibility associated" epitope was "ignored" by specific CD4 T cells, whereas the "resistance-associated" epitope induced clonal deletion and Treg induction in the thymus. Central tolerance was autoimmune regulator dependent and required expression and presentation of PLP by thymic epithelial cells (TECs). TEC specific ablation of PLP revealed that peripheral tolerance, mediated by dendritic cells through recessive tolerance mechanisms (deletion and anergy), could largely compensate for a lack of central tolerance. However, adoptive EAE was exacerbated in mice lacking PLP in TECs, pointing toward a non-redundant role of the thymus in dominant tolerance to PLP. Our findings reveal multiple layers of tolerance to a central nervous system autoantigen that vary among epitopes and thereby specify disease susceptibility. Understanding how different modalities of tolerance apply to distinct T cell epitopes of a target in autoimmunity has implications for antigen-specific strategies to therapeutically interfere with unwanted immune reactions against self. PMID- 29170669 TI - Introducing Membrane Charge and Membrane Potential to T Cell Signaling. AB - While membrane models now include the heterogeneous distribution of lipids, the impact of membrane charges on regulating the association of proteins with the plasma membrane is often overlooked. Charged lipids are asymmetrically distributed between the two leaflets of the plasma membrane, resulting in the inner leaflet being negatively charged and a surface potential that attracts and binds positively charged ions, proteins, and peptide motifs. These interactions not only create a transmembrane potential but they can also facilitate the formation of charged membrane domains. Here, we reference fields outside of immunology in which consequences of membrane charge are better characterized to highlight important mechanisms. We then focus on T cell receptor (TCR) signaling, reviewing the evidence that membrane charges and membrane-associated calcium regulate phosphorylation of the TCR-CD3 complex and discuss how the immunological synapse exhibits distinct patterns of membrane charge distribution. We propose that charged lipids, ions in solution, and transient protein interactions form a dynamic equilibrium during T cell activation. PMID- 29170670 TI - Metabolic Adaptation of Human CD4+ and CD8+ T-Cells to T-Cell Receptor-Mediated Stimulation. AB - Linking immunometabolic adaptation to T-cell function provides insight for the development of new therapeutic approaches in multiple disease settings. T-cell activation and downstream effector functions of CD4+ and CD8+ T-cells are controlled by the strength of interaction between the T-cell receptor (TCR) and peptides presented by human leukocyte antigens (pHLA). The role of TCR-pHLA interactions in modulating T-cell metabolism is unknown. Here, for the first time, we explore the relative contributions of the main metabolic pathways to functional responses in human CD4+ and CD8+ T-cells. Increased expression of hexokinase II accompanied by higher basal glycolysis is demonstrated in CD4+ T cells; cytokine production in CD8+ T-cells is more reliant on oxidative phosphorylation. Using antigen-specific CD4+ and CD8+ T-cell clones and altered peptide ligands, we demonstrate that binding affinity tunes the underlying metabolic shift. Overall, this study provides important new insight into how metabolic pathways are controlled during antigen-specific activation of human T cells. PMID- 29170671 TI - B7-H1 Influences the Accumulation of Virus-Specific Tissue Resident Memory T Cells in the Central Nervous System. AB - Therapies that target the PD-1/B7-H1 axis have revolutionized cancer treatment, yet precise knowledge of how this pathway provides benefit continues to evolve. Here, we report a novel role for the immune checkpoint ligand B7-H1 in the accumulation of tissue-resident memory CD8+ T-cells (TRM). After intracranial infection, Theiler's murine encephalomyelitis virus (TMEV) generates TRM that are maintained in the central nervous system (CNS) tissues of B7-H1WT animals. Although no differences in acute T-cell responses between B7-H1WT and B7-H1KO are observed, at long-term periods post-infection the maintenance of CD8+ TRM is diminished in B7-H1KO animals. This is accompanied by redistribution of the resident CD8+ population from primarily CD103+ TRM to a diminished population of TRM and a preponderance of non-specified PD-1+ CD103- CD8+ T-cells. T-cell transfer studies demonstrate that host B7-H1 is necessary for maintaining TRM and limiting accumulation of PD-1+ CD103- CD8+ T-cells. The lack of host B7-H1 results in compromised control of a heterologous virus re-challenge demonstrating a functional defect in TRM mediated virus control. This study reveals a new role for B7-H1 in TRM and pro-inflammatory PD-1+ CD103- CD8+ T-cell accumulation in the CNS and gives insight for using B7-H1/PD-1 blockade in modulating long-term T cell protection. PMID- 29170672 TI - Triterpene Structural Diversification by Plant Cytochrome P450 Enzymes. AB - Cytochrome P450 monooxygenases (P450s) represent the largest enzyme family of the plant metabolism. Plants typically devote about 1% of the protein-coding genes for the P450s to execute primary metabolism and also to perform species-specific specialized functions including metabolism of the triterpenes, isoprene-derived 30-carbon compounds. Triterpenes constitute a large and structurally diverse class of natural products with various industrial and pharmaceutical applications. P450-catalyzed structural modification is crucial for the diversification and functionalization of the triterpene scaffolds. In recent times, a remarkable progress has been made in understanding the function of the P450s in plant triterpene metabolism. So far, ~80 P450s are assigned biochemical functions related to the plant triterpene metabolism. The members of the subfamilies CYP51G, CYP85A, CYP90B-D, CYP710A, CYP724B, and CYP734A are generally conserved across the plant kingdom to take part in plant primary metabolism related to the biosynthesis of essential sterols and steroid hormones. However, the members of the subfamilies CYP51H, CYP71A,D, CYP72A, CYP81Q, CYP87D, CYP88D,L, CYP93E, CYP705A, CYP708A, and CYP716A,C,E,S,U,Y are required for the metabolism of the specialized triterpenes that might perform species-specific functions including chemical defense toward specialized pathogens. Moreover, a recent advancement in high-throughput sequencing of the transcriptomes and genomes has resulted in identification of a large number of candidate P450s from diverse plant species. Assigning biochemical functions to these P450s will be of interest to extend our knowledge on triterpene metabolism in diverse plant species and also for the sustainable production of valuable phytochemicals. PMID- 29170674 TI - A Pectin Methylesterase ZmPme3 Is Expressed in Gametophyte factor1-s (Ga1-s) Silks and Maps to that Locus in Maize (Zea mays L.). AB - The ga1 locus of maize confers unilateral cross incompatibility, preventing cross pollination between females carrying the incompatible Ga1-s allele and males not carrying a corresponding compatible allele. To characterize this system at the molecular level, we carried out a transcript profiling experiment in which silks from near isogenic lines carrying the Ga1-s and ga1 alleles were compared. While several differentially expressed genes were identified, only one mapped to the known location of ga1. This gene is a pectin methylesterase (PME), which we designated as ZmPme3, and is present and expressed only in Ga1-s genotypes. While a functional ZmPME3 is not present in the ga1 genotypes examined, a pectin methylesterase gene cluster is found in ga1 genotypes. The gene cluster in W22 contains 58 tandem full-length or partial PME pseudo genes. These data combined with a wealth of previously published data on the involvement of PMEs in pollen tube growth suggest a role for cell wall modification enzymes in the pollen exclusion component of Ga1-s gametophytic incompatibility. Consistent with this role, a third allele which lacks the female function of Ga1-s, Ga1-m, has a mutationally inactivated version of ZmPme3. PMID- 29170673 TI - Mutant Transcriptome Sequencing Provides Insights into Pod Development in Peanut (Arachis hypogaea L.). AB - Pod size is the major yield component and a key target trait that is selected for in peanut breeding. However, although numerous quantitative trait loci (QTLs) for peanut pod size have been described, the molecular mechanisms underlying the development of this characteristic remain elusive. A peanut mutant with a narrower pod was developed in this study using ethyl methanesulfonate (EMS) mutagenesis and designated as the "pod width" mutant line (pw). The fresh pod weight of pw was only about 40% of that seen in the wild-type (WT) Zhonghua16, while the hull and seed filling of the mutant both also developed at earlier stages. Pods from both pw and WT lines were sampled 20, 40, and 60 days after flowering (DAF) and used for RNA-Seq analysis; the results revealed highly differentially expressed lignin metabolic pathway genes at all three stages, but especially at DAF 20 and DAF 40. At the same time, expression of genes related to auxin signal transduction was found to be significantly repressed during the pw early pod developmental stage. A genome-wide comparative analysis of expression profiles revealed 260 differentially expressed genes (DEGs) across all three stages, and two candidate genes, c26901_g1 (CAD) and c37339_g1 (ACS), responsible for pod width were identified by integrating expression patterns and function annotation of the common DEGs within the three stages. Taken together, the information provided in this study illuminates the processes underlying peanut pod development, and will facilitate further identification of causal genes and the development of improved peanut varieties with higher yields. PMID- 29170676 TI - Plasticity in Meristem Allocation as an Adaptive Strategy of a Desert Shrub under Contrasting Environments. AB - The pattern of resource allocation to reproduction vs. vegetative growth is a core component of a plant's life-history strategy. Plants can modify their biomass allocation patterns to adapt to contrasting environments. Meristems can have alternative fates to commit to vegetative growth, reproduction, or remaining inactive (dormant or senescent/dead). However, knowledge about whether meristem fates can interpret adaptive changes in biomass allocation remains largely unknown. We measured aboveground plant biomass (a proxy of plant size) and meristem number of a dominant shrub Artemisia ordosica in three populations occupying different habitats in the Mu Us Desert of northern China. Size dependent biomass allocation and meristem allocation among habitats were compared. The size-dependent biomass allocation and meristem allocation of A. ordosica strongly varied across habitats. There were significant positive linear relationships between meristem allocation and biomass allocation in all habitats, indicating that meristem allocation is an indicator of the estimated resource allocation to reproductive and vegetative organs in this species. Plasticity in meristem allocation was more likely caused by larger individuals having less active meristems due to environmental stress. Vegetative meristems (VM) were likely more vulnerable to environmental limitation than reproductive ones, resulting in the ratio of resource investment between vegetative and reproductive functions exhibiting plasticity in different habitats. A. ordosica invested a higher fraction of its resource to reproduction in the adverse habitat, while more resource to vegetative growth in the favorable habitat. A. ordosica adopts different resource allocation patterns to adapt to contrasting habitat conditions through altering its meristem fates. Our results suggest that the arid-adapted shrub A. ordosica deactivates more VM than reproductive ones to hedge against environmental stress, representing an important adaptive strategy. This information contributes to understand the life-history strategies of long-lived plants under stressful environments.

AB - Terpenes are an important group of secondary metabolites in carrots influencing taste and flavor, and some of them might also play a role as bioactive substances with an impact on human physiology and health. Understanding the genetic and molecular basis of terpene synthases (TPS) involved in the biosynthesis of volatile terpenoids will provide insights for improving breeding strategies aimed at quality traits and for developing specific carrot chemotypes possibly useful for pharmaceutical applications. Hence, a combination of terpene metabolite profiling, genotyping-by-sequencing (GBS), and genome-wide association study (GWAS) was used in this work to get insights into the genetic control of terpene biosynthesis in carrots and to identify several TPS candidate genes that might be involved in the production of specific monoterpenes. In a panel of 85 carrot cultivars and accessions, metabolite profiling was used to identify 31 terpenoid volatile organic compounds (VOCs) in carrot leaves and roots, and a GBS approach was used to provide dense genome-wide marker coverage (>168,000 SNPs). Based on this data, a total of 30 quantitative trait loci (QTLs) was identified for 15 terpenoid volatiles. Most QTLs were detected for the monoterpene compounds ocimene, sabinene, beta-pinene, borneol and bornyl acetate. We identified four genomic regions on three different carrot chromosomes by GWAS which are both associated with high significance (LOD >= 5.91) to distinct monoterpenes and to TPS candidate genes, which have been identified by homology-based gene prediction utilizing RNA-seq data. In total, 65 TPS candidate gene models in carrot were identified and assigned to known plant TPS subfamilies with the exception of TPS d and TPS-h. TPS-b was identified as largest subfamily with 32 TPS candidate genes.

Leaves by Near Infrared Hyperspectral Imaging. AB - Nitrate is an important component of the nitrogen cycle and is therefore present in all plants. However, excessive nitrogen fertilization results in a high nitrate content in vegetables, which is unhealthy for humans. Understanding the spatial distribution of nitrate in leaves is beneficial for improving nitrogen assimilation efficiency and reducing its content in vegetables. In this study, near-infrared (NIR) hyperspectral imaging was used for the non-destructive and effective evaluation of nitrate content in spinach (Spinacia oleracea L.) leaves. Leaf samples with different nitrate contents were collected under various fertilization conditions, and reference data were obtained using reflectometer apparatus RQflex 10. Partial least squares regression analysis revealed that there was a high correlation between the reference data and NIR spectra (r2 = 0.74, root mean squared error of cross-validation = 710.16 mg/kg). Furthermore, the nitrate content in spinach leaves was successfully mapped at a high spatial resolution, clearly displaying its distribution in the petiole, vein, and blade. Finally, the mapping results demonstrated dynamic changes in the nitrate content in intact leaf samples under different storage conditions, showing the value of this non-destructive tool for future analyses of the nitrate content in vegetables. PMID- 29170677 TI - DWARF14, A Receptor Covalently Linked with the Active Form of Strigolactones, Undergoes Strigolactone-Dependent Degradation in Rice. AB - Strigolactones (SLs) are the latest confirmed phytohormones that regulate shoot branching by inhibiting bud outgrowth in higher plants. Perception of SLs depends on a novel mechanism employing an enzyme-receptor DWARF14 (D14) that hydrolyzes SLs and becomes covalently modified. This stimulates the interaction between D14 and D3, leading to the ubiquitination and degradation of the transcriptional repressor protein D53. However, the regulation of SL perception in rice remains elusive. In this study, we provide evidences that D14 is ubiquitinated after SL treatment and degraded through the 26S proteasome system. The Lys280 site of the D14 amino acid sequence was important for SL-induced D14 degradation, but did not change the subcellular localization of D14 nor disturbed the interaction between D14 and D3, nor D53 degradation. Biochemical and genetic analysis indicated that the key amino acids in the catalytic center of D14 were essential for D14 degradation. We further showed that D14 degradation is dependent on D3 and is tightly correlated with protein levels of D53. These findings revealed that D14 degradation takes place following D53 degradation and functions as an important feedback regulation mechanism of SL perception in rice.

PMID- 29170680 TI - Family structure, maternal employment, and change in children's externalizing problem behaviour: Differences by age and self-regulation. AB - This study used a latent difference score growth model to investigate how changes in family structure (biological father and stepfather residence) and maternal employment are associated with American children's externalizing problem behaviors (EPB) from ages 4 to 10 and whether these associations vary by children's level of self-regulation. For all 4 year old children, living with a biological father at age 4 was associated with reductions in EPB at ages 4-6 and later years, with no variation by child self-regulation. Living with a stepfather at age 4 was associated with higher levels of EPB at age 4; however, for less regulated children, stepfather residence at ages 4 and 8 was associated with reductions in EPB between ages 4-6 and from 8-10, respectively. Greater employment hours were associated with increased EPB in the next two years for less-regulated children of all ages; however, except for the age 4-6 transition, there was a lagged association that reduced behavior problems after two years and outweighed short-term increases. PMID- 29170681 TI - Education, substance use, and HIV risk among orphaned adolescents in Eastern Zimbabwe. AB - There is a growing interest in education as a means to reduce HIV infection in vulnerable children in sub-Saharan Africa; however, the mechanisms by which education reduces HIV infection remain uncertain. Substance use has been associated with high-risk sexual behaviour and could lie on the causal pathway between education and HIV risk. Therefore, we used multivariable regression to measure associations between: (i) orphanhood and substance use (alcohol, recreational drugs, and smoking), (ii) substance use and sexual risk behaviours, and (iii) school enrolment and substance use, in adolescents aged 15-19 years, in Eastern Zimbabwe. We found substance use to be low overall (6.4%, 3.2%, and 0.9% of males reported alcohol, drug, and cigarette use; <1% of females reported any substance use), but was more common in male maternal and double orphans than non orphans. Substance use was positively associated with early sexual debut, number of sexual partners, and engaging in transactional sex, while school enrolment was associated with lower substance use in males. We conclude that education may reduce sexual risk behaviours and HIV infection rates among male adolescents in sub-Saharan Africa, in part, by reducing substance abuse. PMID- 29170682 TI - Adaptive Skill Trajectories in Infants with Fragile X Syndrome Contrasted to Typical Controls and Infants at High Risk for Autism. AB - Background: Adaptive behaviors are essential for optimal outcomes and independence in individuals with developmental disabilities. This study examined longitudinal trajectories of adaptive behavior in infants with fragile X syndrome (FXS), compared to typical development (TD) and infant siblings of children diagnosed with autism (ASIBs). Method: Participants included 76 male infants (FXS =25, ASIBs=27, TD = 24) assessed up to 4 times between 6 and 24 months of age for a total of 215 assessments of adaptive behavior. A sample of 12 females with FXS was included for a comparative sex analysis. Results: Results indicate that infant males with FXS displayed lower initial adaptive behavior across all domains that emerged by 9 months-of-age with slower growth rates than both comparison groups. A flat profile across the domains at 24 months was evident. Increased severity of autism symptoms was related to reduced adaptive skills at 24 months-of-age. Females with FXS displayed higher scores than males on the Socialization and Motor domains and equivalent scores on the Communication and Daily Living domains at 9 months-of-age with different rates of growth across domains. Conclusions: This is the first study to provide evidence of etiological specificity in adaptive behavior profiles during infancy across two populations at high risk for ASD. These findings support targeted adaptive behavior interventions in young children with FXS beginning as early at 9 months of age to reduce identified deficits and the cascading impacts of these early impairments. PMID- 29170683 TI - A Systematic Review of Research into the Impact of Loose Parts Play on Children's Cognitive, Social and Emotional Development. AB - Loose parts play (LPP) interventions introduce moveable materials and equipment to children's play spaces to facilitate unstructured, child-led play. Meta analysis of previous school-based research has shown significant benefits of LPP for physical activity. In the current paper, we review the scope and quality of the quantitative evidence relating to cognitive, social and emotional outcomes. We conducted a systematic search of the literature on LPP interventions for primary school-aged children which used quantitative outcome indicators for cognitive, social and/or emotional development. Studies were screened for inclusion by two independent researchers and reviewed for content, relevant outcomes and quality indicators. Five studies met the review inclusion criteria. Two studies used a randomised controlled trial design, two studies used quasi experimental design, and one used an observational design. Outcomes measured focused mainly on social development. With the exception of enjoyment, school satisfaction and self-esteem, emotional outcomes were almost entirely absent. No measures of cognitive or academic outcomes were found. For the studies using control groups, few differences between groups were reported, although one study found increased happiness at school and increased odds of reporting being pushed/shoved at playtime associated with intervention. Null results were found for peer acceptance, relational bullying, social competence, social skills, peer group size and psychosocial quality of life. In the non-controlled study, there were observed increases in co-operative play. There is insufficient high-quality, quantitative, empirical evidence available to determine whether or not LPP interventions have an impact on children's cognitive, social and emotional development. We conclude our review with some recommendations which we hope will assist future research in this promising field. PMID- 29170684 TI - From basics to clinic: Cancer Nanotechnology. PMID- 29170685 TI - Connection Between Thermodynamics and Dynamics of Simple Fluids in Pores: Impact of Fluid-Fluid Interaction Range and Fluid-Solid Interaction Strength. AB - Using molecular simulations, we investigate how the range of fluid-fluid (adsorbate-adsorbate) interactions and the strength of fluid-solid (adsorbate adsorbent) interactions impact the strong connection between distinct adsorptive regimes and distinct self-diffusivity regimes reported in [Krekelberg, W. P.; Siderius, D. W.; Shen, V. K.; Truskett, T. M.; Errington, J. R. Langmuir2013, 29, 14527-14535]. Although increasing the fluid-fluid interaction range changes both the thermodynamics and the dynamic properties of adsorbed fluids, the previously reported connection between adsorptive filling regimes and self-diffusivity regimes remains. Increasing the fluid-fluid interaction range leads to enhanced layering and decreased self-diffusivity in the multilayer-formation regime but has little effect on the properties within film-formation and pore-filling regimes. We also find that weakly attractive adsorbents, which do not display distinct multilayer formation, are hard-sphere-like at super- and subcritical temperatures. In this case, the self-diffusivity of the confined and bulk fluid has a nearly identical scaling-relationship with effective density. PMID- 29170686 TI - Charge-Transfer Analysis of 2p3d Resonant Inelastic X-ray Scattering of Cobalt Sulfide and Halides. AB - We show that with 2p3d resonant inelastic X-ray scattering (RIXS) we can accurately determine the charge-transfer parameters of CoF2, CoCl2, CoBr2, and CoS. The 160 meV resolution RIXS results are compared with charge-transfer multiplet calculations. The improved resolution and the direct observation of the crystal field and charge-transfer excitations allow the determination of more accurate parameters than could be derived from X-ray absorption and X-ray photoemission, both limited in resolution by their lifetime broadening. We derive the crystal field and charge-transfer parameters of the Co2+ ions, which provides the nature of the ground state of the Co2+ ions with respect to symmetry and hybridization. In addition, the increased spectral resolution allows the more accurate determination of the atomic Slater integrals. The results show that the crystal field energy decreases with increasing ligand covalency. The L2 edge RIXS spectra show that the intensity of the (Coster-Kronig induced) nonresonant X-ray emission is a measure of ligand covalency. PMID- 29170687 TI - Methane Adsorption in Zr-Based MOFs: Comparison and Critical Evaluation of Force Fields. AB - The search for nanoporous materials that are highly performing for gas storage and separation is one of the contemporary challenges in material design. The computational tools to aid these experimental efforts are widely available, and adsorption isotherms are routinely computed for huge sets of (hypothetical) frameworks. Clearly the computational results depend on the interactions between the adsorbed species and the adsorbent, which are commonly described using force fields. In this paper, an extensive comparison and in-depth investigation of several force fields from literature is reported for the case of methane adsorption in the Zr-based Metal-Organic Frameworks UiO-66, UiO-67, DUT-52, NU 1000, and MOF-808. Significant quantitative differences in the computed uptake are observed when comparing different force fields, but most qualitative features are common which suggests some predictive power of the simulations when it comes to these properties. More insight into the host-guest interactions is obtained by benchmarking the force fields with an extensive number of ab initio computed single molecule interaction energies. This analysis at the molecular level reveals that especially ab initio derived force fields perform well in reproducing the ab initio interaction energies. Finally, the high sensitivity of uptake predictions on the underlying potential energy surface is explored. PMID- 29170688 TI - Emergence of Nonlinear Optical Activity by Incorporation of a Linker Carrying the p-Nitroaniline Motif in MIL-53 Frameworks. AB - p-Nitroaniline presents the typical motif of a second-order nonlinear optically (NLO) active molecule. However, because of its crystallization in an antiparallel and hence centrosymmetric structure, the NLO activity is lost. In this contribution, the p-nitroaniline motif was built successfully into the MIL-53 metal-organic framework. More precisely, MIL-53 was synthesized with 2-amino-5 nitroterephthalate as organic linker, with Al3+, Ga3+, or In3+ as inorganic cation. The Al and Ga structures are polar, as confirmed by second-harmonic generation microscopy, yielding stable NLO materials. Indeed, they contain a 22 36% surplus of the dipolar 2-amino-5-nitro-terephthalate oriented in a parallel fashion. The indium compound was shown to be less crystalline and centrosymmetric. Ab initio modeling of the second-order NLO response shows that the Al and Ga materials show a response comparable to typical inorganic commercial NLO materials such as KDP. As a hybrid material, capable of low temperature synthesis and processing and the ultrafast NLO responses associated with organic materials, this material can potentially provide an interesting venue for applications with respect to traditional inorganic NLO materials. PMID- 29170689 TI - Perception of Community Tolerance and Prevalence of Depression among Transgender Persons. AB - Purpose: The goal of the study was to examine the association between depression and perceived community tolerance after controlling for various demographic and personal characteristics, treatment receipt, and past experiences with abuse or discrimination. Methods: An on-line survey assessed depressive symptoms among transgender and gender non-conforming individuals. Depression was assessed using the 7-item Beck Depression Inventory for Primary Care (BDI-PC) and the 10-item Center for Epidemiologic Studies Depression (CESD-10) scale. Results: The prevalence ratios (95% confidence intervals) comparing depression in persons who did and did not perceive their area as tolerant were 0.33 (0.20-0.54) for BD-PC and 0.66 (0.49-0.89) for CESD-10. Other factors associated with depression were experience with abuse or discrimination, lower education, and unfulfilled desire to receive hormonal therapy. Conclusion: Depression was common in this sample of transgender and gender non-conforming individuals and was strongly and consistently associated with participants' perceptions of community tolerance, even after adjusting for possible confounding. The association between desire to receive hormonal therapy and depression is a finding that warrants further exploration. Future research should also assess depression and changes in perception of community tolerance in transgender individuals before and after initiation of gender confirmation treatment. PMID- 29170690 TI - Correlation between the Functional Movement Screen and Hip Mobility in NCAA Division II Athletes. AB - The Functional Movement Screen (FMS) is a series of seven exercises designed to assess athletes prior to competitive training to determine dysfunctional movement patterns. The exercises include the deep squat (DS), hurdle step (HS), inline lunge (IL), shoulder mobility (SM), active straight leg raise (ASL), pushup (PU), and rotary stability (RS), all of which comprise the composite score (FMS CS). The purpose of this study was to determine correlations between the FMS screens and hip mobility. The specific hip range-of-motion exercises used were bilateral internal/external rotation (IRR, IRL ERL, ERR), and flexion/extension (FL, FR, ER, EL). Participants of both genders (32 males, 13 females) were solicited from four sports (baseball, softball, and men's and women's cross-country). The most significant/intriguing correlations were between FMS HS/FL, FMS ILL/R, FMS PU/FL, FMS ALL and IRR/L and ERR/L and FMS SM/ER. All correlations produced were weak to moderate at the .05 level of significance. These results demonstrate that hip range-of-motion plays a minor role in FMS score. Future studies should utilize a larger sample size, including more females, as well as analyze range-of-motion across multiple joints. PMID- 29170691 TI - Does Time Heal all Wounds? A Case Study on Rival Perceptions Before and After Conference Realignment. AB - The current longitudinal case study investigated how conference realignment and beginning new annual competitions impacted fan rival perceptions for fans of the Texas A&M Aggies, Missouri Tigers, and Texas Christian University Horned Frogs. In particular, fan rival perceptions before and after conference realignment were compared to determine if significant differences were present. Findings indicate that history plays an important role in rivalry as fans of teams sharing longstanding rivalries with schools in their previous conference (i.e., Texas A&M/Texas and Missouri/Kansas) did not differ in their rival perceptions before or after conference realignment. On the other hand, rival perceptions of TCU fans significantly differed in their perceptions of Boise State (previous rival) and Baylor (current rival) before and after conference realignment. Implications for sport managers are discussed. PMID- 29170692 TI - "I will change the world": The Intersection of Social Change and Male College Athletes' Leadership Perspectives. AB - Historically, men have been characterized as task-oriented leaders who are motivated by desires for autonomy, wealth, and power (17, 33). However, these "masculine" views of leadership might not accurately capture the leadership motivations of Millennial males as the views were developed in previous generations (4). Given the commitment of many Millennials towards socially responsible attitudes and behaviors (18, 25), we utilized a qualitative research design to examine the influence of social change on the leadership motivations of Millennial male intercollegiate athletes. In doing so, we found participants were motivated to lead in order to affect social change within their communities and within society. Our findings indicate a new perspective, one which includes a commitment to social change, is potentially needed when discussing "masculine" views of leadership. PMID- 29170693 TI - From Crisis to De-escalation: An Examination of Politics in a U.S. High School Steroid Testing Program. AB - Preventing the use of performance enhancing drugs in sport has long been a concern for policymakers. In the United States, amidst national attention the state of Texas constructed the country's largest steroid testing program for high school athletes. However, resource allocation steadily declined until the program was defunded in 2015. Using escalation of commitment theory as a framework, this conceptual paper examines the critical, but less studied, role of politics and de escalation behavior that directed this distinct sport situation. By combining policy and media documents with the academic literature, this paper allows for a greater understanding of how the steroid testing program was formulated and implemented, which may influence how policymakers address steroids among amateur athletes in the future. This paper also offers new opportunities for future research by highlighting a new sport context in which escalation of commitment theory applies and specifically noting the significant role politics can play in escalation or de-escalation decision making. PMID- 29170694 TI - The Relationship Between Athletic Identity and Academic Major Chosen by Student Athletes. AB - This study examines the correlation between athletic identity and academic major selection among intercollegiate student-athletes. A thorough review of literature focusing on academic clustering, athletic identity, and academic development leads to the development of two hypotheses - 1) student-athletes with stronger athletic identity will have a declared major of decreased academic rigor; and 2) student-athletes with stronger athletic identity will be more likely to be undecided on their major. Data were collected through a survey administered to Division I, II, and III student-athletes recording academic major and their Athletic Identity Measurement Scale (AIMS). After analyzing the student responses, Hypothesis I is supported, while Hypothesis II is met with some limitation that leads to a lack of statistical significance. Overall, this study sheds light on a connection between academic choice and athletic identity. PMID- 29170695 TI - Students' Perceptions of an Applied Research Experience in an Undergraduate Exercise Science Course. AB - Applied research experiences can provide numerous benefits to undergraduate students, however few studies have assessed the perceptions of Exercise Science (EXS) students to an applied research experience. The purpose of this study was two-fold: 1) to describe the rationale and implementation of an applied research experience into an EXS curriculum and 2) to evaluate EXS undergraduate students' perceptions of an applied research experience. An EXS measurement course was chosen for implementation of an applied research experience. The applied research experience required groups of students to design, implement, and evaluate a student-led research project. Fourteen questions were constructed, tailored to EXS undergraduate students, to assess students' perceptions of the experience. Qualitative analysis was used for all applicable data, with repeated trends noted; quantitative data were collapsed to determine frequencies. There was an overall positive student perception of the experience and 85.7% of students agreed an applied research experience should be continued. 84.7% of students perceived the experience as educationally enriching, while 92.8% reported the experience was academically challenging. This experience allowed students to develop comprehensive solutions to problems that arose throughout the semester; while facilitating communication, collaboration, and problem solving. Students believed research experiences were beneficial, but could be time consuming when paired with other responsibilities. Results suggest an applied research experience has the potential to help further the development of EXS undergraduate students. Understanding student perceptions of an applied research experience may prove useful to faculty interested in engaging students in the research process. PMID- 29170696 TI - Speed- and Circuit-Based High-Intensity Interval Training on Recovery Oxygen Consumption. AB - Due to the current obesity epidemic in the United States, there is growing interest in efficient, effective ways to increase energy expenditure and weight loss. Research has shown that high-intensity exercise elicits a higher Excess Post-Exercise Oxygen Consumption (EPOC) throughout the day compared to steady state exercise. Currently, there is no single research study that examines the differences in Recovery Oxygen Consumption (ROC) resulting from high-intensity interval training (HIIT) modalities. The purpose of this study is to review the impact of circuit training (CT) and speed interval training (SIT), on ROC in both regular exercising and sedentary populations. A total of 26 participants were recruited from the UW-Eau Claire campus and divided into regularly exercising and sedentary groups, according to self-reported exercise participation status. Oxygen consumption was measured during and after two HIIT sessions and was used to estimate caloric expenditure. There was no significant difference in caloric expenditure during and after exercise among individuals who regularly exercise and individuals who are sedentary. There was also no significant difference in ROC between regular exercisers and sedentary or between SIT and CT. However, there was a significantly higher caloric expenditure in SIT vs. CT regardless of exercise status. It is recommended that individuals engage in SIT vs. CT when the goal is to maximize overall caloric expenditure. With respect to ROC, individuals can choose either modalities of HIIT to achieve similar effects on increased oxygen consumption post-exercise. PMID- 29170697 TI - Effects of Flexibility and Balance on Driving Distance and Club Head Speed in Collegiate Golfers. AB - Good balance, flexibility, and strength are all required to maintain a steady stance during the kinematic chain to produce successful golf shots. When the body can produce more power, more club head speed is generated. This formation of power translates into greater distance and accuracy. Athletes today are seeking exercise programs to enhance these qualities of their golf swing. The purpose of this study is to investigate the correlations between flexibility and balance with club head speed and driving distance in the golf swing of male and female collegiate golfers. Five male and five female collegiate golfers participated in the study. They completed multiple range of motion tests, the Balance Error System Test, and multiple flexibility tests. Subjects then participated in a short hitting session. Ten shots were hit with the subject's own driver. The Optishot simulator measured distance and club head speed generated. There was a significant negative correlation between the BESS test score and average distance for male subjects (r=-0.850, p=0.034). There were also a few trends between the balance, flexibility, and club head speed findings of both male and female subjects. This data shows there is a significant relationship between better balance and driving the ball farther. Other trends show better balance and flexibility will result in greater driving distance and club head speed. Balance and flexibility exercises should be incorporated into a golfer's practice or workout regiment. PMID- 29170698 TI - Effects of the Boy Scouts of America Personal Fitness Merit Badge on Cardio Metabolic Risk, Health Related Fitness and Physical Activity in Adolescent Boys. AB - A growing number of adolescents are more sedentary and have fewer formal opportunities to participate in physical activity. With the mounting evidence that sedentary time has a negative impact on cardiometabolic profiles, health related fitness and physical activity, there is a pressing need to find an affordable adolescent physical activity intervention. One possible intervention that has been overlooked in the past is Boy Scouts of America. There are nearly 900,000 adolescent boys who participate in Boy Scouts in the United States. The purpose of this research study was to evaluate the effect of the Personal Fitness merit badge system on physical activity, health-related fitness, and cardio metabolic blood profiles in Boy Scouts 11-17 years of age. Participants were fourteen (N = 14) Boy Scouts from the Great Salt Lake Council of the Boy Scouts of America who earned their Personal Fitness merit badge. Classes were held in the Spring of 2016 where boys received the information needed to obtain the merit badge and data were collected. Results from the related-samples Wilcoxon signed rank test showed that the median of differences between VO2 peak pre-test and post-test scores were statistically significant (p = 0.004). However, it also showed that the differences between the Pre-MetS (metabolic syndrome) and Post MetS scores (p = 0.917), average steps taken per day (p = 0.317), and BMI (p = 0.419) were not statistically significant. In conclusion, the merit badge program had a positive impact on cardiovascular endurance, suggesting this program has potential to improve cardiovascular fitness and should be considered for boys participating in Boy Scouts. PMID- 29170700 TI - The Effect of a Single Bout of Surfing on Exercise-Induced Affect. AB - Exercise-induced affect (EIA) has been well documented and is often composed of positive affect, negative affect, tranquility, and fatigue. Research on EIA has focused on mainstream sports such as running, walking, or cycling; however, no research has evaluated the influence of action sports participation in activities such surfing on EIA. The current study examined the effect of a single 30-min surfing bout on EIA in 107 adult volunteers. An additional purpose was if change in affect was similar based on surfing history, surfing frequency, and surfing skill level. To assess EIA, each participant completed the Physical Activity Affect Scale (PAAS) prior to and immediately following the 30-min surf session. Dependent t-tests were used to examine differences between pre- and post-test EIA. For the secondary purpose, a change score (PAAS posttest-PAAS pretest) was computed for each subscale. One-way ANOVAs were performed to determine differences among comparisons of surfing history, surfing frequency, and surfing skill level, and the change score for each of the 4 subscales. EIA was significantly altered by surfing, with significant improvements in positive affect and tranquility, and significant reductions in negative affect and fatigue. There were no significant differences among surfing history, surfing frequency, and surfing skill level, and positive affect, negative affect or tranquility. However, there were significant differences between fatigue and surfing history, surfing frequency, and surfing skill level. The results indicate that a single 30-min surfing bout may provide positive benefits for the participant. Implications for future surfing research and EIA are discussed. PMID- 29170699 TI - Validity of Arm-to-Arm BIA Devices Compared to DXA for Estimating % Fat in College Men and Women. AB - Bioelectric impedance analysis (BIA) devices are commonly used to estimate percent body fat (%fat), although validation of their accuracy varies widely. The purpose of this study was to assess the validity of four commonly used BIA devices compared to dual-energy X-ray absorptiometry (DXA). College-aged men (n = 29, age = 19.7 +/- 1.2 y, weight = 76.9 +/- 12.5 kg) and women (n = 31, age = 20.5 +/- 0.8 y, weight = 61.5 +/- 9.2 kg) were evaluated for %fat using four single-frequency (50 mHz) BIA devices and DXA. A gender * device repeated measures ANOVA indicated some less expensive BIA devices produced %fat values that were not significantly different from DXA. A thumb-to-thumb BIA device produced the closest values in men (21.9 +/- 6.6%) and women (32.1 +/- 5.3%) compared to DXA (20.6 +/- 6.1% and 30.3 +/- 5.4%, respectively). The two more expensive BIA devices significantly underestimated in men (14.7 +/- 5.8% and 17.0 +/- 5.6%) and women (23.3 +/- 4.2% and 23.3 +/- 4.2%) compared to DXA. Interclass correlation coefficients with DXA were higher for the more expensive devices in men (ICC = 0.899 and 0.958) than the less expensive devices (ICC = 0.681 and 0.730). In women, all BIA devices showed moderate correlations with DXA (ICC = 0.537 to 0.658). Despite the convenience of simple BIA devices, their use in estimating body composition in young men and women might be questionable due to large variations in the differences between DXA and each device in this study.

Participants (16 women, 14 men, college students 19-26 years) performed 2 sets of leg press to failure using 150% of their body mass with 5 min rest separating the 2 sets. Each exercise was performed twice (1* MS, 1* PL) at the same time of day with 48 h separating each exercise. Both MS and PL were ingested 30 min prior to performing the exercise. Just prior to starting the exercise and at the end of each set, heart rate, and blood pressure were obtained and the rate pressure product was calculated to determine myocardial workload. Two-way repeated measures ANOVA for lift number showed no significant main effects for either MS vs. PL, or for Set1 vs. Set2 (p > 0.05). The interaction was also not statistically different (mean repetitions +/- std. dev.: MS1= 28+/-20, MS2= 26+/-18, PL1 = 30+/-24, PL2 = 29+/-20). Two-way repeated measures ANOVA for rate pressure product showed no significance for either the main effect for MS vs. PL, or supplement * pre-post interaction (p > 0.05). The main effect for pre-lift vs. post lift was significant (p<0.001) with post being higher than pre. Ingestion of Muscle Sentry(r) 30 min prior to leg pressing 150% of body mass to failure had no effect upon either total work performance or myocardial workload. PMID- 29170702 TI - College Student Work Habits are Related to Physical Activity and Fitness. AB - Despite the known benefits of regular physical activity, research shows a significant decline in physical activity participation and an increase in sedentary behavior during young adulthood during the college years. Studies examining the relationship between academic outcomes and fitness/physical activity have not extensively examined this among college students. Therefore, the purpose of this study was to examine the relationship between fitness measures (cardiovascular endurance, muscular endurance, flexibility and body composition), physical activity, and academic outcomes in college students. This cross-sectional study had college students complete a one-time fitness assessment and survey examining their physical activity and academic factors (GPA, study habits, course load). Correlations examined relationships between fitness, physical activity and academic outcomes, t-tests compared differences for fitness and behavioral outcomes between groups by academic factors. The final sample (n=512) was 50.4% male, 78% Non-Hispanic White, and 67% upperclassmen. The majority (76%) of participants reported meeting current PA guidelines. Hours of studying and social media use were both positively associated with body fat. Course load was negatively associated with vigorous activity. Study time was negatively associated with cardiovascular endurance, positively associated with hip flexibility and sedentary behavior. Higher GPA was associated with a higher BMI and a higher credit load was associated with less vigorous physical activity. These findings indicated that academic outcomes and physical activity may have a different relationship among college students compared with younger age groups. This study provides insight for the development of future campus-based health initiatives to have a shared focus of academic outcomes and physical activity. PMID- 29170703 TI - Nutrient Intake of Elite Canadian and American Athletes with Spinal Cord Injury. AB - The nutrient needs of athletes with Spinal Cord Injury (SCI) are dependent on their physiological alterations and training status. Limited research is available regarding dietary intake of elite athletes with SCI and possible nutrient deficiencies. Therefore, the purpose of this study was to examine dietary intake of elite athletes with SCI, and determine dietary intake inadequacies based on the Estimated Average Requirement (EAR) comparisons. Additionally, the average energy and macronutrient (carbohydrate, protein, and fat) intake was compared based on level of injury (C level, T1-T6, T7-T12, Lumbar). A total of 39 athletes with a SCI completed a self-reported 24 hour diet recall in autumn and 27 athletes returned to complete a second data collection period (winter). Nutrient inadequacy was estimated by the proportion of athletes with mean intakes below the EAR through the Research Solutions Food Processor Diet Analysis Software (ESHA). Although Macronutrients for both men and women were within acceptable macronutrient distribution range (AMDR) recommendations, low EAR's for various nutrients were consistently found for both men and women. No significant differences were found for energy or macronutrient intake between groups based on level of lesion. Further research is needed to examine nutrient intake using other methods of dietary assessment and to determine the factors that may lead to nutrient insufficiency among elite athletes with SCI. PMID- 29170704 TI - A Pre-Exercise Dose of Melatonin Can Alter Substrate Use During Exercise. AB - Notwithstanding the lack of exercise research, several reviews have championed the use of melatonin to combat metabolic syndrome. Therefore, this study compared substrate utilization during a 30-minute (min) graded exercise protocol following the ingestion of either 6 mg melatonin (M) or a placebo (P). Participants (12 women, 12 men) performed stages 1-5 of the Naughton graded exercise protocol (6 min per stage). The protocol was repeated 4 times (2x M, 2x P) at the same time of day with one week separating each session. Expired gases were monitored, VO2 and respiratory exchange ratio (RER) output was provided every 30s. Total, carbohydrate (CHO), and fat energy expenditures were obtained from the RER values using the formulae of Lusk. The VO2 at which CHO accounted for 50% of the total caloric expenditure was calculated by a VO2: RER regression line. Additionally, the energy derived was calculated by multiplying VO2 and the respective energy expenditures. Then, the total, CHO, and fat energies consumed during the 30 min of exercise were determined by calculating the area under the kJ/min: time curve using the trapezoid rule. The final data for the two similar trials were averaged and a paired-T test was used for statistical comparison. The average VO2 for 50% CHO usage was significantly lower following M (0.84 +/- 0.54 l.min-1) than after P (1.21 +/- 0.52 l.min-1). Also, average CHO kJ for M (627 +/- 284) was significantly (p < 0.004) greater than P (504 +/- 228), and accounted for a significantly greater contribution of total kJ consumed (M = 68% +/-15 vs. P = 61% +/- 18). Ingestion of melatonin 30 min prior to an aerobic exercise bout elevates CHO use during exercise. PMID- 29170705 TI - Energy Cost of Active and Sedentary Music Video Games: Drum and Handheld Gaming vs. Walking and Sitting. AB - To compare energy expenditure during and after active and handheld video game drumming compared to walking and sitting. Ten experienced, college-aged men performed four protocols (one per week): no-exercise seated control (CTRL), virtual drumming on a handheld gaming device (HANDHELD), active drumming on drum pads (DRUM), and walking on a treadmill at ~30% of VO2max (WALK). Protocols were performed after an overnight fast, and expired air was collected continuously during (30min) and after (30min) exercise. DRUM and HANDHELD song lists, day of the week, and time of day were identical for each participant. Significant differences (p < 0.05) among the average rates of energy expenditure (kcal.min-1) during activity included WALK > DRUM > HANDHELD. No significant differences in the rates of energy expenditure among groups during recovery were observed. Total energy expenditure was significantly greater (p < 0.05) during WALK (149.5 +/- 30.6 kcal) compared to DRUM (118.7 +/- 18.8 kcal) and HANDHELD (44.9+/-11.6 kcal), and greater during DRUM compared to HANDHELD. Total energy expenditure was not significantly different between HANDHELD (44.9 +/- 11.6 kcal) and CTRL (38.2 +/- 6.0 kcal). Active video game drumming at expert-level significantly increased energy expenditure compared to handheld, but it hardly met moderate-intensity activity standards, and energy expenditure was greatest during walking. Energy expenditure with handheld video game drumming was not different from no-exercise control. Thus, traditional aerobic exercise remains at the forefront for achieving the minimum amount and intensity of physical activity for health, individuals desiring to use video games for achieving weekly physical activity recommendations should choose games that require significant involvement of lower body musculature, and time spent playing sedentary games should be a limited part of an active lifestyle. PMID- 29170706 TI - The Effects of Resistance Training Volume on Skeletal Muscle Proteome. AB - Studies are conflicting to whether low volume resistance training (RT) is as effective as high-volume RT protocols with respect to promoting morphological and molecular adaptations. Thus, the aim of the present study was to compare, using a climbing a vertical ladder, the effects of 8 weeks, 3 times per week, resistance training with 4 sets (RT4), resistance training with 8 sets (RT8) and without resistance training control (CON) on gastrocnemius muscle proteome using liquid chromatography mass spectrometry (LC-MS/MS) and cross sectional area (CSA) of rats. Fifty-two proteins were identified by LC-MS/MS, with 39 in common between the three groups, two in common between RT8 and CON, one in common between RT8 and RT4, four exclusive in the CON, one in the RT8, and four in the RT4. The RT8 group had a reduced abundance of 12 proteins, mostly involved in muscle protein synthesis, carbohydrate metabolism, tricarboxylic acid cycle, anti-oxidant defense, and oxygen transport. Otherwise one protein involved with energy transduction as compared with CON group showed high abundance. There was no qualitative protein abundance difference between RT4 and CON groups. These results revealed that high volume RT induced undesirable disturbances on skeletal muscle proteins, while lower volume RT resulted in similar gains in skeletal muscle hypertrophy without impairment of proteome. The CSA was significantly higher in RT8 group when compared to RT4 group, which was significantly higher than CON group. However, no differences were found between trained groups when the gastrocnemius CSA were normalized by the total body weight. PMID- 29170707 TI - Is the Relationship Between Stride Length, Frequency, and Velocity Influenced by Running on a Treadmill or Overground? AB - The purpose of the study was to compare the relationship between stride length (SL), stride frequency (SF), and velocity while running on a treadmill and overground. Participants (n=10; 22.3+/-2.6 yrs; 1.71+/-.08 m; 71.4+/-15.5 kg) completed a total of 14 runs (7 treadmill, 7 overground) with each run at a different velocity. SL, SF, and velocity data were recorded using wearable technology (Garmin, Fenix2). The outdoor trials occurred first. The treadmill velocities were selected to match the range of velocities used overgroud. SL vs. velocity plots were generated for treadmill and overground data for each participant and fit with a 2nd order polynomial in the form of SL=Av2+Bv+C. Each equation coefficient (i.e., A, B, C) was averaged across participants and compared between treadmill and overground using paired t-tests. The A coefficient (v2 term) was different treadmill vs. overground (p=0.031). Neither B (p=0.136) nor C (p=0.260) coefficients were different treadmill vs. overground. It was concluded that the A coefficient (v2 term) for SL vs. velocity was larger during overground vs. treadmill running. This is an indication that the strategy of changing SL across velocities was different when on the treadmill vs. overground. Specifically, while running on a treadmill, SL continued to increase in a more linear manner than when running overground. PMID- 29170709 TI - Effects of Heat Exposure on Body Water Assessed using Single-Frequency Bioelectrical Impedance Analysis and Bioimpedance Spectroscopy. AB - The purpose of this study was to determine if heat exposure alters the measures of total body water (TBW), extracellular water (ECW), and intracellular water (ICW) in both single-frequency bioelectrical impedance analysis (BIA) and bioimpedance spectroscopy (BIS). Additionally, we sought to determine if any differences exist between the BIA and BIS techniques before and after brief exposure to heat. Body water was evaluated for twenty men (age=24+/-4 years) in a thermoneutral environment (22 degrees C) before (PRE) and immediately after (POST) 15 min of passive heating (35 degrees C) in an environmental chamber. The mean difference and 95% limits of agreement at PRE demonstrated that BIS yielded significantly higher body water values than BIA (all p<0.05; TBW=1.8kg; ECW=0.6+/ 1.3kg; ICW=1.2+/-3.7kg). However, the effect size (ES) of the mean differences at PRE were small and the r-values were high (r>=0.97). TBW and ICW remained significantly higher at POST for BIS (both p<0.05; 1.4+/-3.2kg and 1.1+/-3.7kg, respectively) whereas ECW was not different (p>0.05; 0.2+/-1.5kg). Additionally, the ES of the mean differences at POST were trivial to small and the r-values were high (r>=0.96). When analyzing the changes in body water before and after heat exposure, POST values for BIS were significantly higher than PRE (all p<0.001; TBW=0.6+/-0.8kg; ECW=0.4+/-0.3kg; ICW=0.3+/-0.6kg). Similarly, POST values for BIA were significantly higher than PRE (all p<0.001; TBW=1.0+/-0.6kg; ECW=0.7+/-0.4kg; ICW=0.4+/-0.4kg). BIA and BIS provide similar body water estimates. However, the increase in POST body water values indicate more research is needed before either method can be used for estimating body water after heat exposure. PMID- 29170708 TI - Repeated Plyometric Exercise Attenuates Blood Glucose in Healthy Adults. AB - Plyometric exercise is popular in commercial exercise programs aiming to maximize energy expenditure for weight loss. However, the effect of plyometric exercise on blood glucose is unknown. The purpose of this study was to investigate the effect of relatively high intensity plyometric exercise on blood glucose. Thirteen subjects (6 females age= 21.8 +/- 1.0 yrs.; height= 163.7 +/- 7.8 cm; mass= 60.8 +/- 6.7 kg and 7 males age= 22.0 +/- 2.6 yrs.; height= 182.3 +/- 3.6 cm; mass= 87.4 +/- 12.5 kg) volunteered to participate. Subjects completed two random conditions on two separate days, consisting of either five sets of 10 maximal effort countermovement squat jumps (SJ) with 50 seconds' rest between sets or quiet sitting (SIT) for the time equated to the SJ duration (~4min). Immediately after each condition, subjects drank 75g of anhydrous glucose (CHO) in 100ml of water. Blood glucose measurements were taken via finger prick pre and immediately post SJ or SIT, and 5, 15, 30, and 60 min post. A 2*6 (condition * time) ANOVA revealed a significant interaction where SJ blood glucose was lower at 15 (114.0 +/- 14.6 mg/dl) and 30 (142.1 +/- 22.5 mg/dl) min compared to SIT (15min 130.8 +/ 14.0 mg/dl and 30min 159.3 +/- 21.0 mg/dl). The current plyometric protocol attenuated CHO-induced blood glucose at 15 and 30 min. This may be due to increased physiological stress applied to the muscles, thus increasing muscular glucose uptake. PMID- 29170710 TI - Validation of the Functional Assessment of Chronic Illness Therapy-Spiritual Well Being-Expanded (FACIT-Sp-Ex) Across English and Spanish-Speaking Hispanics/Latinos: Results From the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study. AB - The validity of the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp) has been examined in primarily non-Hispanics/Latinos with chronic illness. This study assessed the psychometric properties of the non illness, expanded FACIT-Sp (FACIT-Sp-Ex) in 5,163 U.S. Hispanic/Latino adults. Measures were interviewer-administered in English or Spanish. Confirmatory factor analyses indicated four factors: Meaning, Peace, Faith, and Relational. The scale demonstrated measurement invariance across English and Spanish. Subscales displayed adequate internal and test-retest reliability. Scores were positively associated with Duke Religion Index (DUREL) subscales. When all subscales were entered in a single model, Meaning and Peace were inversely associated with depressive symptoms and positively associated with HRQOL. Faith was positively associated with depressive symptoms and inversely associated with HRQOL. Relational was not associated with any outcome. FACIT-Sp-Ex subscales were generally more strongly associated than DUREL subscales with well-being. The FACIT-Sp-Ex appears to be a valid measure of spiritual well-being in U.S. Hispanics/Latinos. PMID- 29170711 TI - Correlation of Planned Dose to Area Postrema and Dorsal Vagal Complex with Clinical Symptoms of Nausea and Vomiting in Oropharyngeal Cancer (OPC) patients treated with radiation alone using IMRT. AB - Objective: To correlate the planned dose to the nausea center (NC) - area postrema (AP) and dorsal vagal complex (DVC) - with nausea and vomiting symptoms in OPC patients treated with IMRT without chemotherapy. We also investigated whether it was possible to reduce doses to the NC without significant degradation of the clinically accepted treatment plan. Methods: From 11/04 to 4/09, 37 OPC patients were treated with definitive or adjuvant IMRT without chemotherapy. Of these, only 23 patients had restorable plans and were included in this analysis. We contoured the NC with the assistance of an expert board-certified neuroradiologist. We searched for correlation between the delivered dose to the NC and patient-reported nausea and vomiting during IMRT. We used one-paired t test: two-sample assuming equal variances to compare differences in dose to NC between symptomatic and asymptomatic patients. We then replanned each case to determine if reduced dose to the NC could be achieved without compromising coverage to target volumes, increasing unwarranted hotspots or increasing dose to surrounding critical normal tissues. Results: Acute symptoms of nausea were as follows: Grade 0 (n=6), Grade 1 (n=13), Grade 2 (n=3), and Grade 3 (n=1). Patients with no complaints of nausea had a median dose to the DVC of 34.2 Gy (range 4.6-46.6 Gy) and AP of 32.6 Gy (range 7.0-41.4Gy); whereas those with any complaints of nausea had a median DVC dose of 40.4 Gy (range 19.3-49.4 Gy) and AP dose of 38.7 Gy (range 16.7-46.8 Gy) (p=0.04). Acute vomiting was as follows: Grade 0 (n=17), Grade 1 (n=4), Grade 2 (n=1), and Grade 3 (n=1). There was no significant difference in DVC or AP dose among those with and without vomiting symptoms (p=0.28).Upon replanning of each case to minimize dose to the NC, we were, on average, able to reduce the radiation dose to AP by 18% and DVC by 17%; while the average dose variations to the PTV coverage, brainstem, cord, temporal lobes, and cochlea were never greater than 3%. Hotspots increased by 2% for 3 patients while hotspots for remaining patients were less than 2% variation. Conclusion: For OPC cancer patients treated with IMRT without chemotherapy, dose to AP and DVC may be associated with development of nausea. We were able to show that reducing doses substantially to the NC is achievable without significant alteration of the clinically accepted plan and may reduce the incidence and grade of nausea. As symptoms of nausea can be devastating to patients, one can consider routine contouring and constraining of the NC to minimize chances of having this complication.

AB - Thiazolines and thiazoles are an integral part of numerous natural products, a number of drugs, and many useful molecules such as ligands for metal catalysis. We report the first common synthetic protocol for the synthesis of thiazoles and thiazolines. Novel molecules are efficiently synthesized by using readily available and inexpensive substrates. The reaction conditions are mild and pure products are obtained without work-up and column purification. PMID- 29170714 TI - Reduced Bimolecular Recombination in Blade-Coated, High-Efficiency, Small Molecule Solar Cells. AB - To realize the full promise of solution deposited photovoltaic devices requires processes compatible with high-speed manufacturing. We report the performance and morphology of blade-coated bulk heterojunction devices based on the small molecule donor p-DTS(FBTTh2)2 when treated with a post-deposition solvent vapor annealing (SVA) process. SVA with tetrahydrofuran improves the device performance of blade-coated films more than solvent additive processing (SA) with 1,8 diiodooctane. In spin-coating, SA and SVA achieve similar device performance. Our optimized, blade coated, SVA devices achieve power conversion efficiencies over 8 % and maintain high efficiencies in films up to ~ 250 nm thickness, providing valuable resilience to small process variations in high-speed manufacturing. Using impedance spectroscopy, we show that this advantageous behavior originates from highly suppressed bimolecular recombination in the SVA-treated films. Electron microscopy and grazing-incidence X-ray scattering experiments show that SA and SVA both produce highly crystalline donor domains, but SVA films have a radically smaller domain size compared to SA films. We attribute the different behavior to variations in initial nucleation density and relative ability of SVA and SA to control subsequent crystal growth. PMID- 29170712 TI - Chemical probes and inhibitors of bromodomains outside the BET family. AB - In the last five years, the development of inhibitors of bromodomains has emerged as an area of intensive worldwide research. Emerging evidence has implicated a number of non-BET bromodomains in the onset and progression of diseases such as cancer, HIV infection and inflammation. The development and use of small molecule chemical probes has been fundamental to pre-clinical evaluation of bromodomains as targets. Recent efforts are described highlighting the development of potent, selective and cell active non-BET bromodomain inhibitors and their therapeutic potential. Over half of typical bromodomains now have reported ligands, but those with atypical binding site residues remain resistant to chemical probe discovery efforts. PMID- 29170715 TI - Biocompatible, degradable thermoplastic polyurethane based on polycaprolactone block-polytetrahydrofuran-block-polycaprolactone copolymers for soft tissue engineering. AB - Biodegradable synthetic polymers have been widely used as tissue engineering scaffold materials. Even though they have shown excellent biocompatibility, they have failed to resemble the low stiffness and high elasticity of soft tissues because of the presence of massive rigid ester bonds. Herein, we synthesized a new thermoplastic polyurethane elastomer (CTC-PU(BET)) using poly ester ether triblock copolymer (polycaprolactone-block-polytetrahydrofuran-block polycaprolactone triblock copolymer, PCTC) as the soft segment, aliphatic diisocyanate (hexamethylene diisocyanate, HDI) as the hard segment, and degradable diol (bis(2-hydroxyethyl) terephthalate, BET) as the chain extender. PCTC inhibited crystallization and reduced the melting temperature of CTC PU(BET), and BET dramatically enhanced the thermal decomposition and hydrolytic degradation rate when compared with conventional polyester-based biodegradable TPUs. The CTC-PU(BET) synthesized in this study possessed a low tensile modulus and tensile strength of 2.2 MPa and 1.3 MPa, respectively, and an elongation-at break over 700%. Meanwhile, it maintained a 95.3% recovery rate and 90% resilience over ten cycles of loading and unloading. In addition, the TPU could be electrospun into both random and aligned fibrous scaffolds consisting of major microfibers and nanobranches. 3T3 fibroblast cell culture confirmed that these scaffolds outperformed the conventional biodegradable TPU scaffolds in terms of substrate-cellular interactions and cell proliferation. Considering the advantages of this TPU, such as ease of synthesis, low cost, low stiffness, high elasticity, controllable degradation rate, ease of processability, and excellent biocompatibility, it has great prospects to be used as a tissue engineering scaffold material for soft tissue regeneration. PMID- 29170716 TI - POSS-ProDOT Crosslinking of PEDOT. AB - Alkoxy-functionalized polythiophenes such as poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(3,4-propylenedioxythiophene) (PProDOT) have become promising materials for a variety of applications including bioelectronic devices due to their high conductivity, relatively soft mechanical response, good chemical stability and excellent biocompatibility. However the long-term applications of PEDOT and PProDOT coatings are still limited by their relatively poor electrochemical stability on various inorganic substrates. Here, we report the synthesis of an octa-ProDOT-functionalized polyhedral oligomeric silsesquioxane (POSS) derivative (POSS-ProDOT) and its copolymerization with EDOT to improve the stability of PEDOT coatings. The POSS-ProDOT crosslinker was synthesized via thiol-ene "click" chemistry, and its structure was confirmed by both Nuclear Magnetic Resonance and Fourier Transform Infrared spectroscopies. PEDOT copolymer films were then electrochemically deposited with various concentrations of the crosslinker. The resulting PEDOT-co-POSS-ProDOT copolymer films were characterized by Cyclic Voltammetry, Electrochemical Impedance Spectroscopy, Ultraviolet-Visible spectroscopy and Scanning Electron Microscopy. The optical, morphological and electrochemical properties of the copolymer films could be systematically tuned with the incorporation of POSS-ProDOT. Significantly enhanced electrochemical stability of the copolymers was observed at intermediate levels of POSS-ProDOT content (3.1 wt%). It is expected that these highly stable PEDOT-co-POSS-ProDOT materials will be excellent candidates for use in bioelectronics devices such as neural electrodes.

PMID- 29170718 TI - Resting state fMRI connectivity analysis as a tool for detection of abnormalities in five different cognitive networks of the brain in Multiple Sclerosis patients. AB - Objectives: Cognitive dysfunction is present in at least half of patients with Multiple Sclerosis. The purpose of this study was to examine functional connectivity abnormalities in patients with multiple sclerosis (MS) using resting state fMRI (rsfMRI). Methods: Conventional MRI, rsfMRI and diffusion tensor imaging (DTI) data was acquired from 10 patients with relapsing-remitting multiple sclerosis (RRMS) and 20 healthy controls. Cross-correlation of the resting state average signal among the voxels in each brain region of the five cognitive networks: default mode network (DMN), attention, verbal memory, memory, and visuospatial working memory network, was calculated. Voxelwise analyses were used to investigate fractional anisotropy (FA) of white matter tracts. The normalized gray matter (GM), white matter and thalamus volumes were calculated. Results: Compared to controls, significant deficit in MS patients at each of five networks, attention (p=0.026), DMN (p=0.004), verbal memory (p<0.001), memory (p=0.001), visuospatial working memory (p=0.003) was found. Significant reduction (p=0.034) in the normalized GM volume and asymmetry in thalamus volume (p=0.041) was detected in MS patients compared to controls. Conclusion: Wide spread of functional abnormalities are present within different cognitive networks in patients with RRMS, suggesting that DMN may not be sufficient for measurement of MS cognitive impairment. Larger and longitudinal studies should ascertain whether rsfMRI of cognitive networks and changes in GM and thalamus volume can be used as tools for assessment of cognition in clinical trials in MS. PMID- 29170719 TI - Subclinical Hypothyroidism and Its Association with Increased Cardiovascular Mortality. AB - Thyroid hormones play an important role in regulating different metabolism functions and multiple organs' performance. Changes in the thyroid hormone axis can lead to profound effects on the stability of vital organs and systems, especially the cardiovascular system. Hypothyroidism is classified according to the clinical presentation as overt and subclinical. There is some evidence supporting the benefits of thyroxine hormone replacement for subclinical hypothyroidism on cardiovascular mortality outcomes. However, the clinical relevance of measuring and treating high thyroid-stimulating hormone (TSH) levels in newly diagnosed heart failure patients with preserved ejection fraction requires further study. In this report, we review the current evidence regarding the prognostic significance of subclinical hypothyroidism in heart failure patients with preserved ejection fraction. PMID- 29170721 TI - A GENERAL FRAMEWORK FOR MINIMIZING ENERGY CONSUMPTION OF SERIES ELASTIC ACTUATORS WITH REGENERATION. AB - The use of actuators with inherent compliance, such as series elastic actuators (SEAs), has become traditional for robotic systems working in close contact with humans. SEAs can reduce the energy consumption for a given task compared to rigid actuators, but this reduction is highly dependent on the design of the SEA's elastic element. This design is often based on natural dynamics or a parameterized optimization, but both approaches have limitations. The natural dynamics approach cannot consider actuator constraints or arbitrary reference trajectories, and a parameterized elastic element can only be optimized within the given parameter space. In this work, we propose a solution to these limitations by formulating the design of the SEA's elastic element as a non parametric convex optimization problem, which yields a globally optimal conservative elastic element while respecting actuator constraints. Convexity is proven for the case of an arbitrary periodic reference trajectory with a SEA capable of energy regeneration. We discuss the optimization results for the tasks defined by the human ankle motion during level-ground walking and the natural motion of a single mass-spring system with a nonlinear spring. For all these tasks, the designed SEA reduces energy consumption and satisfies the actuator's constraints. PMID- 29170720 TI - Methionine adenosyltransferases in liver health and diseases. AB - Methionine adenosyltransferases (MATs) are essential for cell survival because they catalyze the biosynthesis of the biological methyl donor S adenosylmethionine (SAMe) from methionine and adenosine triphosphate (ATP). Mammalian cells express two genes, MAT1A and MAT2A, which encode two MAT catalytic subunits, alpha1 and alpha2, respectively. The alpha1 subunit organizes into dimers (MATIII) or tetramers (MATI). The alpha2 subunit is found in the MATII isoform. A third gene MAT2B, encodes a regulatory subunit beta, that regulates the activity of MATII by lowering the inhibition constant (Ki) for SAMe and the Michaelis constant (Km) for methionine. MAT1A expressed mainly in hepatocytes maintains the differentiated state of these cells whereas MAT2A and MAT2B are expressed in non-parenchymal cells of the liver (hepatic stellate cells [HSCs] and Kupffer cells) and extrahepatic tissues. A switch from the liver specific MAT1A to MAT2A has been observed during conditions of active liver growth and de-differentiation. Liver injury, fibrosis, and cancer are associated with MAT1A silencing and MAT2A/MAT2B induction. Even though both MAT1A and MAT2A are involved in SAMe biosynthesis, they exhibit distinct molecular interactions in liver cells. This review provides an update on MAT genes and their roles in liver pathologies. PMID- 29170723 TI - Homologue distribution patterns of 2,3,7,8-chloro-substituted PCDD/F in Bavarian soils. AB - Background: Soil-background values of PCDD/F concentrations are usually conveniently displayed as toxic equivalent (TEq), being a bulk parameter of all relevant 7 PCDD- and 10 PCDF-congeneres, chloro-subsidized at the 2nd, 3rd, 7th and 8th carbon atom. Data here are ample, not so survey on congenere/homologue patterns occurring in soils. The sufficient number of samples taken within this analysis allowed first a well-grounded evaluation. Results: OCDD proved to be the dominant congenere in all samples (forest and agriculture), however, in considerably different concentrations. As expected, highest level was detected in forest organic layers, followed by forest top soils, cropland- and grassland top soils. Although highest in concentration, OCDD only contributes to 0.17% (both forest organic- and top soil layer), respectively, 0.4% (cropland) and 0.3% (grassland) to TEq. The influence of lower chlorinated homologues on TEq is strongest in forest top soils (72%) followed by 67% (forest organic layers), cropland top soil (63%) and grassland (61%). Although all homologue patterns (forest and agriculture) give a fairly similar picture, a test of significance (chi2) proved a different population of forest samples. Conclusions: The resemblance of the homologue patterns throughout all utilization suggests that agent levels are explained mainly by diffuse atmospheric depositions rather than by specific land use input. PMID- 29170722 TI - What Drives False Memories in Psychopathology? A Case for Associative Activation. AB - In clinical and court settings, it is imperative to know whether posttraumatic stress disorder (PTSD) and depression may make people susceptible to false memories. We conducted a review of the literature on false memory effects in participants with PTSD, a history of trauma, or depression. When emotional associative material was presented to these groups, their levels of false memory were raised relative to those in relevant comparison groups. This difference did not consistently emerge when neutral or nonassociative material was presented. Our conclusion is supported by a quantitative comparison of effect sizes between studies using emotional associative or neutral, nonassociative material.

AB - Recently, ultrasound (US)-based drug delivery strategies have received attention to improve enhanced permeation and retention (EPR) effect-based passive targeting efficiency of nanoparticles in vitro and in vivo conditions. Among the US treatment techniques, pulsed-high intensity focused ultrasound (pHIFU) have specialized for improving tissue penetration of various macromolecules and nanoparticles without irreversible tissue damages. In this study, we have demonstrated that pHIFU could be utilized to improve tissue penetration of fluorescent dye-labeled glycol chitosan nanoparticles (FCNPs) in femoral tissue of mice. pHIFU could improve blood flow of the targeted-blood vessel in femoral tissue. In addition, tissue penetration of FCNPs was specifically increased 5.7-, 8- and 9.3-folds than that of non-treated (0 W pHIFU) femoral tissue, when the femoral tissue was treated with 10, 20 and 50 W of pHIFU, respectively. However, tissue penetration of FCNPs was significantly reduced after 3 h post-pHIFU treatment (50 W). Because overdose (50 W) of pHIFU led to irreversible tissue damages, including the edema and chapped red blood cells. These overall results support that pHIFU treatment can enhance the extravasation and tissue penetration of FCNPs as well as induce irreversible tissue damages. We expect that our results can provide advantages to optimize pHIFU-mediated delivery strategy of nanoparticles for further clinical applications.

AB - This paper presents a feasibility study of a brain-machine interface system to assist repetitive facilitation exercise. Repetitive facilitation exercise is an effective rehabilitation method for patients with hemiplegia. In repetitive facilitation exercise, a therapist stimulates the paralyzed part of the patient while motor commands run along the nerve pathway. However, successful repetitive facilitation exercise is difficult to achieve and even a skilled practitioner cannot detect when a motor command occurs in patient's brain. We proposed a brain machine interface system for automatically detecting motor commands and stimulating the paralyzed part of a patient. To determine motor commands from patient electroencephalogram (EEG) data, we measured the movement-related cortical potential (MRCP) and constructed a support vector machine system. In this paper, we validated the prediction timing of the system at the highest accuracy by the system using EEG and MRCP. In the experiments, we measured the EEG when the participant bent their elbow when prompted to do so. We analyzed the EEG data using a cross-validation method. We found that the average accuracy was 72.9% and the highest at the prediction timing 280 ms. We conclude that 280 ms is the most suitable to predict the judgment that a patient intends to exercise or not. PMID- 29170725 TI - Reduction of Cognitive Decline in Patients with or at High Risk for Diabetes. AB - Purpose of review: The incidence of Alzheimer's disease and related disorders is expected to triple by 2050. People with type 2 diabetes and prediabetes have a higher risk of cognitive dysfunction, including Alzheimer's disease and vascular dementia. Controversy remains about when and how to prevent and treat cognitive dysfunction in people with or at high risk of diabetes. Recent findings: In our review of ongoing clinical trials, we have found that there has been an increase in the number of studies assessing the efficacy of pharmacological and non pharmacological approaches to prevent or slow down cognitive impairment among people with or at high risk of diabetes. Summary: Despite the considerable risk of cognitive impairment in people with diabetes and prediabetes, there is not enough evidence to support a specific treatment to prevent or slow mild cognitive impairment, or progression to Alzheimer's disease or related disorders. Several ongoing trials are attempting to identify the usefulness of several compounds, as well as lifestyle changes including exercise and diet. Direct mechanisms linking diabetes to cognitive decline have not been elucidated. PMID- 29170727 TI - Grasping state estimation of printable soft gripper using electro-conductive yarn. AB - Automatic handling of many types of food materials are required to realize the automation of production of commercially prepared box lunches. A printable soft gripper was developed for food handling which is simple to produce with a 3D printer. However, the sensing ability of the printable soft gripper was not discussed in previous research. In this paper, a novel method for estimating the grasping state of a printable soft gripper using electro-conductive yarn is presented. Electro-conductive yarn is a conductive material, and the resistance of strings is changed by stretching. It is less expensive than other sensors that can be used for measurement of grasping state. Additionally, it is easy to assemble and disassemble by hand. Electro-conductive yarn is applied to a prototype printable soft gripper, and the proposed estimation method is verified experimentally. From the experimental results, the estimated grasping state from the resistance of the electro-conductive yarn coincides with the actual grasping state of the gripper. Our proposed method of using electro-conductive yarn was successful for estimating the grasping state of a printable soft gripper. PMID- 29170729 TI - Aerial pruning mechanism, initial real environment test. AB - In this research, a pruning mechanism for aerial pruning tasks is tested in a real environment. Since the final goal of the aerial pruning robot will be to prune tree branches close to power lines, some experiments related to wireless communication and pruning performance were conducted. The experiments consisted of testing the communication between two XBee RF modules for monitoring purposes as well as testing the speed control of the circular saw used for pruning tree branches. Results show that both the monitoring and the pruning tasks were successfully done in a real environment. PMID- 29170728 TI - Dynamics and control of separable coupled rigid body systems. AB - This paper explores the dynamics of separable coupled rigid body systems, a special class of constrained rigid body systems. These are defined as two systems that interact with each other by forces of contact, resulting in a reduction in dimensionality and complexity. The mechanics and consequences of this reduction are investigated here. The basic hypothesis and an example of the reduction in two successive steps are formulated. A simple mechanical biped model is developed and analyzed in some details by both system theoretical concepts and simulations. The main contribution of this work is the novel extension to the known dynamics of constrained rigid bodies. The modular, versatile and systematic formulation presented here is computationally efficient and has many applications in the studies of the human neuro-musculoskeletal system, robotic systems and humanoids, as well as clinical and sports biomechanics applications. Computer simulations are provided to demonstrate the feasibility and effectiveness of the methodology. PMID- 29170730 TI - Improving low-cost inertial-measurement-unit (IMU)-based motion tracking accuracy for a biomorphic hyper-redundant snake robot. AB - This paper develops and experimentally validates a 3D-printed snake robot prototype. Its structure is designed to allocate limited room for each functional module (including an external power module, battery power module, the wireless control and transmission module and some detective sensors), so as to ensure the snake robot works in different environments. In order to control and track the snake robot, a low-cost MEMS-IMU (micro-electro-mechanical systems inertial measurement unit)-based snake robot motion tracking system is developed. Three algorithms (low-pass filter, baseline calibration, and Kalman filter) are used to eliminate noise from IMU's acceleration data, thus minimizing the noise influence to tracking accuracy. Through signal processing, the IMU acceleration data can be effectively used for motion tracking. The result from the video tracking software is employed as a reference for comparison, so as to evaluate the motion tracking algorithm efficiency. The comparison results demonstrate high efficiency of the proposed IMU-based motion tracking algorithm. PMID- 29170731 TI - Robot-aided electrospinning toward intelligent biomedical engineering. AB - The rapid development of robotics offers new opportunities for the traditional biofabrication in higher accuracy and controllability, which provides great potentials for the intelligent biomedical engineering. This paper reviews the state of the art of robotics in a widely used biomaterial fabrication process, i.e., electrospinning, including its working principle, main applications, challenges, and prospects. First, the principle and technique of electrospinning are introduced by categorizing it to melt electrospinning, solution electrospinning, and near-field electrospinning. Then, the applications of electrospinning in biomedical engineering are introduced briefly from the aspects of drug delivery, tissue engineering, and wound dressing. After that, we conclude the existing problems in traditional electrospinning such as low production, rough nanofibers, and uncontrolled morphology, and then discuss how those problems are addressed by robotics via four case studies. Lastly, the challenges and outlooks of robotics in electrospinning are discussed and prospected. PMID- 29170732 TI - Changes in Saving Cognitions Mediate Hoarding Symptom Change in Cognitive Behavioral Therapy for Hoarding Disorder. AB - Cognitive-behavioral therapy (CBT) is an empirically-supported treatment for hoarding disorder (HD). However, meta-analytic studies suggest that CBT is only modestly effective, and a significant number of individuals with HD remain symptomatic following treatment. To inform the development of more effective and targeted treatments, it will be important to clarify the mechanisms of treatment response in CBT for HD. To this end, the current study examined whether change in maladaptive saving beliefs mediated symptom change in CBT for HD. Sixty-two patients with primary HD completed measures of maladaptive saving cognitions and hoarding severity at pre-, mid-, and post-CBT. Results showed that change in saving cognitions mediated change in all three domains of HD symptoms (i.e., acquiring, difficulty discarding, and excessive clutter), suggesting that cognitive change may be a mechanism of treatment response in CBT. The findings indicate that cognitive change may have an impact on treatment outcomes, and are discussed in terms of cognitive-behavioral theory of HD and potential ways in which to enhance belief change in treatment. PMID- 29170733 TI - Editorial: Metabolism As a Therapeutic Target. PMID- 29170734 TI - The Prevalence and Distribution of Spina Bifida in a Single Major Referral Center in Malaysia. AB - Background: The aim of this study is to review the medical history of patients with spina bifida, encompassing both aperta and occulta types born between the years 2003 until 2016, spanning a 13-year time period. We assessed each patient and maternal parent information, details of the defects, and conditions associated with the primary defect. We also include information on patients' ambulation and education level (where available). Methods: Data from the Department of Patient Information University of Malaya Medical Centre (UMMC), Malaysia was captured from spina bifida patients (ICD10: Q05 spina bifida). Data involved patients referred to UMMC between 2003 and 2016 and/or born in UMMC within that particular time frame. We filtered and extracted the information according to the data of clinical examination, medical review, and social history provided in the medical records. Results: A total of 86 patient records with spina bifida were analyzed. Spina bifida prevalence rate in this study ranged from 1.87 to 8.9 per 1,000 live births depending on weightage. We note that ethnicity was a factor whereby the highest numbers of spina bifida were from Malays (n = 36, 41.86%), followed by equal numbers of Chinese and Indians (n = 24, 27.91%). The highest number of diagnoses reported was myelomeningocele type spina bifida (n = 39, 45.35%). The most common site of the spina bifida lesion was located at the lumbar region irrespective of aperta or occulta types (n = 23, 26.74%). Data on other associated phenotypes of spina bifida such as hydrocephalus and encephalocele was also captured at 37.21% (n = 32) and 1.16% (n = 1), respectively. In terms of mobility, 32.84% (n = 22/67) of patients between the ages 4 and 16 years old were found to be mobile. As many as 36.07% of patients ranging from 5 to 16 years of age (n = 22/61) received formal education ranging from preschool to secondary school. Conclusion: The prevalence of spina bifida in UMMC is as according to international statistics which is in the range of 0.5-10 per 1,000 live births. Majority of the reported cases were males, Malays, full term babies, and of the myelomeningocele phenotype located at the lumbar region.

PMID- 29170738 TI - BIM-Sim: Interactive Simulation of Broadband Imaging Using Mie Theory. AB - Understanding the structure of a scattered electromagnetic (EM) field is critical to improving the imaging process. Mechanisms such as diffraction, scattering, and interference affect an image, limiting the resolution, and potentially introducing artifacts. Simulation and visualization of scattered fields thus plays an important role in imaging science. However, EM fields are high dimensional, making them time-consuming to simulate, and difficult to visualize. In this paper, we present a framework for interactively computing and visualizing EM fields scattered by micro and nano-particles. Our software uses graphics hardware for evaluating the field both inside and outside of these particles. We then use Monte-Carlo sampling to reconstruct and visualize the three-dimensional structure of the field, spectral profiles at individual points, the structure of the field at the surface of the particle, and the resulting image produced by an optical system. PMID- 29170737 TI - How Are Substrate Binding and Catalysis Affected by Mutating Glu127 and Arg161 in Prolyl-4-hydroxylase? A QM/MM and MD Study. AB - Prolyl-4-hydroxylase is a vital enzyme for human physiology involved in the biosynthesis of 4-hydroxyproline, an essential component for collagen formation. The enzyme performs a unique stereo- and regioselective hydroxylation at the C4 position of proline despite the fact that the C5 hydrogen atoms should be thermodynamically easier to abstract. To gain insight into the mechanism and find the origin of this regioselectivity, we have done a quantum mechanics/molecular mechanics (QM/MM) study on wildtype and mutant structures. In a previous study (Timmins et al., 2017) we identified several active site residues critical for substrate binding and positioning. In particular, the Glu127 and Arg161 were shown to form multiple hydrogen bonding and ion-dipole interactions with substrate and could thereby affect the regio- and stereoselectivity of the reaction. In this work, we decided to test that hypothesis and report a QM/MM and molecular dynamics (MD) study on prolyl-4-hydroxylase and several active site mutants where Glu127 or Arg161 are mutated for Asp, Gln, or Lys. Thus, the R161D and R161Q mutants give very high barriers for hydrogen atom abstraction from any proline C-H bond and therefore will be inactive. The R161K mutant, by contrast, sees the regio- and stereoselectivity of the reaction change but still is expected to hydroxylate proline at room temperature. By contrast, the Glu127 mutants E127D and E127Q show possible changes in regioselectivity with the former being more probable to react compared to the latter. PMID- 29170735 TI - A Novel Strategy to Predict Carcinogenicity of Antiparasitics Based on a Combination of DNA Lesions and Bacterial Mutagenicity Tests. AB - Genotoxicity and carcinogenicity testing of pharmaceuticals prior to commercialization is requested by regulatory agencies. The bacterial mutagenicity test was considered having the highest accuracy of carcinogenic prediction. However, some evidences suggest that it always results in false-positive responses when the bacterial mutagenicity test is used to predict carcinogenicity. Along with major changes made to the International Committee on Harmonization guidance on genotoxicity testing [S2 (R1)], the old data (especially the cytotgenetic data) may not meet current guidelines. This review provides a compendium of retrievable results of genotoxicity and animal carcinogenicity of 136 antiparasitics. Neither genotoxicity nor carcinogenicity data is available for 84 (61.8%), while 52 (38.2%) have been evaluated in at least one genotoxicity or carcinogenicity study, and only 20 (14.7%) in both genotoxicity and carcinogenicity studies. Among 33 antiparasitics with at least one old result in in vitro genotoxicity, 15 (45.5%) are in agreement with the current ICH S2 (R1) guidance for data acceptance. Compared with other genotoxicity assays, the DNA lesions can significantly increase the accuracy of prediction of carcinogenicity. Together, a combination of DNA lesion and bacterial tests is a more accurate way to predict carcinogenicity. PMID- 29170739 TI - Market Impacts of Reducing the Prevalence of Bovine Respiratory Disease in United States Beef Cattle Feedlots. AB - Bovine respiratory disease (BRD) is a common endemic disease among North American feedlot cattle. BRD can lead to significant economic losses for individual beef cattle feedlot producers through mortality and morbidity. With promising new management and technology research that could reduce BRD prevalence, this study evaluates the potential impacts of a reduction of BRD in the US beef cattle feedlot sector. Using a multi-market, multi-commodity partial equilibrium economic model of the US agricultural industry, we evaluate the market impacts of reduced BRD to producers from various livestock, meat, and feedstuffs industries. We find that as morbidity and mortality is reduced, beef cattle producers experience losses due to increased supplies (lower beef cattle prices) and increased demand for feedstuff (higher feedstuff prices). Beef cattle processors see gains as the price of beef cattle is lower, whereas feedstuff producers gain from higher feedstuff prices. Producers in the allied industries (pork, lamb, poultry, and eggs) see a small reduction in returns as consumers substitute with less expensive beef products. Consumers see gains in welfare as the increase in beef cattle supply results in lower beef prices. These lower beef prices more than offset the small increases in pork, lamb, poultry, and egg prices. Overall, the potential economic welfare change due to management and technologies that reduce BRD is a net gain for the US society as a whole. PMID- 29170740 TI - Tip Design for Safety of Steerable Needles for Robot-Controlled Brain Insertion. AB - Background: Current practice in neurosurgical needle insertion is limited by the straight trajectories inherent with rigid probes. One technique allowing curvilinear trajectories involves flexible bevel-tipped needles, which bend during insertion due to their asymmetry. In the brain, safety will require avoidance of the sharp tips often used in laboratory studies, in favor of a more rounded profile. Steering performance, on the other hand, requires maximal asymmetry. Design of safe bevel-tipped brain needles thus involves management of this tradeoff by adjusting needle gauge, bevel angle, and fillet (or tip) radius to arrive at a design that is suitably asymmetrical while producing strain, strain rate, and stress below the levels that would damage brain tissue. Methods: Designs with a variety of values of needle radius, bevel angle, and fillet radius were evaluated in finite-element simulations of simultaneous insertion and rotation. Brain tissue was modeled as a hyperelastic, linear viscoelastic material. Based on the literature available, safety thresholds of 0.19 strain, 10 s-1 strain rate, and 120 kPa stress were used. Safe values of needle radius, bevel angle, and fillet radius were selected, along with an appropriate velocity envelope for safe operation. The resulting needle was fabricated and compared with a Sedan side-cutting brain biopsy needle in a study in the porcine model in vivo (N=3). Results: The prototype needle selected was 1.66 mm in diameter, with bevel angle of 10 degrees and fillet radius of 0.25 mm. Upon examination of postoperative CT and histological images, no differences in tissue trauma or hemorrhage were noted between the prototype needle and the Sedan needle. Conclusions: The study indicates a general design technique for safe bevel-tipped brain needles based on comparison with relevant damage thresholds for strain, strain rate, and stress. The full potential of the technique awaits the determination of more exact safety thresholds. PMID- 29170741 TI - Small-scale Triton X-114 Extraction of Hydrophobic Proteins. AB - Here we introduce a protocol for Triton X-114 extraction which we used in our recently-published paper (Taguchi et al., 2013). It is a versatile method to concentrate or partially purify hydrophobic proteins. The presented protocol is based on the protocol published by Bordier (Bordier, 1981) but more simplified and down-scaled for more small-scale and simpler use (Taguchi et al., 2013). Triton X-114 (TX114) is a non-ionic detergent which has a relatively low clouding point at 22 degrees C and separates into detergent (Det) and aqueous (Aq) phase at temperatures above the clouding point. During phase separation, hydrophobic solutes in the TX114 solution are sequestered to the Det phase, while hydrophilic solutes are sequestered to the Aq phase. Utilizing this phenomenon, TX114 extraction is a very versatile technique to efficiently concentrate hydrophobic proteins, especially glycosylphosphatidylinositol (GPI)-anchored proteins like the prion protein (PrP), because they have substantial amounts of highly hydrophobic moieties. Besides, phase separation using TX114 tolerates a variety of conditions, e.g. different pH or relatively low concentrations of guanidine hydrochloride. Since the hydrophobic proteins are sequestered to the Det phase as long as the phase separation occurs, and if the hydrophobicity of the protein of interest is not affected by pH or denaturant, this technique can be also utilized to change buffers or to remove denaturants. When using enzymes or proteases which maintain activities in detergent solutions, TX114 can also be used to separate hydrophobic from the water-soluble hydrophilic moieties upon enzymatic digestion of proteins, as done by us using in vitro digestion of PrP with phosphatidylinositol-specific phospholipase C (Taguchi et al., 2013). PMID- 29170742 TI - Small-scale Subcellular Fractionation with Sucrose Step Gradient. AB - Here, we introduce the protocol for small-scale and simple subcellular fractionation used in our recent publication (Taguchi et al., 2013), which uses homogenization by passing through needles and sucrose step-gradient. Subcellular fractionation is a very useful technique but usually a large number of cells are required. Because we needed subcellular fractionation of transiently-transfected cells, we developed a protocol for smaller numbers of cells. Our protocol for the subcellular fractionation is based on the protocol published by de Araujo and Huber (de Araujo et al., 2007), although substantial modifications have been made according to our experiences and information from personal communications. As optimal conditions seem to vary between cell lines, we advise to further modify the protocol to optimize for individual experiments. Our method is simple but sufficient for analysis of integral membrane proteins or proteins anchored to organelles by glycosylphosphatidylinositol or other lipid anchors, e.g. prion protein. However, proteins non-covalently attached to membranes or membrane proteins of organelles seem to be more prone to dissociation from the organelles during preparation and, if these proteins are the object of study, further modifications might be necessary. Unlike in a continuous gradient, where a protein of interest is scattered over a wide range, step-gradient fractionation is advantageous in detection of relatively small amounts of proteins from small scale experiments, because it concentrates the protein of interest in one fraction, if an appropriate combination of sucrose concentrations is used. PMID- 29170743 TI - Infant Rabbit Colonization Competition Assays. AB - Enteric pathogenic bacteria such as Vibrio cholerae and enteropathogenic Escherichia coli (E. coli) cause life-threatening diarrheal diseases that have afflicted humans for centuries. Understanding the effectors required for intestinal colonization is very important to research on bacteria pathogenesis, and is also important to testing new therapeutics and development of the novel vaccines. Here, we describe the Infant Rabbit Colonization Competition Assay, a variant method of the powerful, nonsurgical animal model reported by Ritchie et al. (2010). In our modified assay, wild type and mutant strains are mixed together and inoculated into 2-day-old New Zealand white rabbits. The competitive index for each mutant measures the colonization capacity of the mutant relative to its wild type parental strain in the gastrointestinal tract. Compared to the traditional Sucking Mice model, the clinical and histologic signs of Vibrio cholerae (V. cholera)-induced disease of infant rabbits more closely resemble human cholera. The larger input bacteria amount of this model also facilitates high-throughput screens, such as Tn-Seq technology (Fu et al., 2013). PMID- 29170744 TI - Murine in vivo CD8+ T Cell Killing Assay. AB - Antigen-specific killing ability of effector CD8+ T cells is critical for protective immunity against infection. Here, we describe in vivo cytotoxic T cell assay to examine effector function of antigen-specific CD8+ T cells. Mice infected with Listeria monocytogenes (L. monocytogenes) expressing chicken ovalbumin as a model antigen mount ovalbumin-specific CD8+ T cell responses. Effector CD8+ T cell function in vivo is determined by mixed transfer of OVA peptide-pulsed target cells with control target cells into the previously immunized mice. Difference in CFSE expression levels clearly marks two distinct populations: Antigen-pulsed target cells-CFSElow vs. unpulsed target cells CFSEhi. The frequencies between antigen-pulsed target cells and control target cells are used as readouts of antigen-specific killing.

AB - The RNA chromatin immunoprecipitation assay (RNA-ChIP) allows detection and quantification of RNA-protein interactions using in vivo cross-linking with formaldehyde followed by immunoprecipitation of the RNA-protein complexes. Here we describe the RNA-ChIP protocol that we have adapted for Caenorhabditis elegans (C. elegans) to detect interaction between the nuclear Argonaute CSR-1 (chromosome segregation and RNAi deficient) protein and its target nascent RNAs. We have used a transgenic strain expressing a recombinant long isoform of CSR-1 protein fused with N-terminal 3x FLAG epitope. PMID- 29170746 TI - Artificial Optogenetic TRN Stimulation of C. elegans. AB - Optogenetics is a powerful tool for manipulating neuronal activity with high temporal and spatial precision. In the nematode C. elegans optogentics is especially useful and easy to apply. This is because C. elegans is translucent, so its neurons are highly accessible to optic stimulation. In addition, many of its neurons can be exclusively targeted using cell-specific promoters. We have recently taken advantage of optogentics to deliver artificial patterns of prolonged activation to a class of mechanosensory neurons, called touch receptor neurons (TRNs) in worms that lack touch sensation due to a genetic mutation. Our aim was to examine whether we can counteract the effects of sensory loss by artificially activating the sensory neurons. Here we describe in detail the various components of the protocol that we used. This consists of exposing worms expressing the light-sensitive ion channel Channelrohdopsin 2 (ChR2) in TRNs to long-term random flashes of light.

PMID- 29170748 TI - Fluorophore Labeling, Nanodisc Reconstitution and Single-molecule Observation of a G Protein-coupled Receptor. AB - Activation of G protein-coupled receptors (GPCRs) by agonist ligands is mediated by a transition from an inactive to active receptor conformation. We describe a novel single-molecule assay that monitors activation-linked conformational transitions in individual GPCR molecules in real-time. The receptor is site specifically labeled with a Cy3 fluorescence probe at the end of trans-membrane helix 6 and reconstituted in phospholipid nanodiscs tethered to a microscope slide. Individual receptor molecules are then monitored over time by single molecule total internal reflection fluorescence microscopy, revealing spontaneous transitions between inactive and active-like conformations. The assay provides information on the equilibrium distribution of inactive and active receptor conformations and the rate constants for conformational exchange. The experiments can be performed in the absence of ligands, revealing the spontaneous conformational transitions responsible for basal signaling activity, or in the presence of agonist or inverse agonist ligands, revealing how the ligands alter the dynamics of the receptor to either stimulate or repress signaling activity. The resulting mechanistic information is useful for the design of improved GPCR targeting drugs. The single-molecule assay is described in the context of the beta2 adrenergic receptor, but can be extended to a variety of GPCRs. PMID- 29170749 TI - In vitro AMPylation Assays Using Purified, Recombinant Proteins. AB - Post-translational protein modifications (PTMs) orchestrate the activity of individual proteins and ensure their proper function. While modifications such as phosphorylation or glycosylation are well understood, more unusual modifications, including nitrosylation or AMPylation remain comparatively poorly characterized. Research on protein AMPylation-which refers to the covalent addition of an AMP moiety to the side chains of serine, threonine or tyrosine-has undergone a renaissance (Yarbrough et al., 2009; Engel et al., 2012; Ham et al., 2014; Woolery et al., 2014; Preissler et al., 2015; Sanyal et al., 2015; Truttmann et al., 2016; Truttmann et al., 2017). The identification and characterization of filamentation (fic) domain-containing AMPylases sparked new interest in this PTM (Kinch et al., 2009; Yarbrough et al., 2009). Based on recent in vivo and in vitro studies, we now know that secreted bacterial AMPylases covalently attach AMP to members of the Rho family of GTPases, while metazoan AMPylases modify HSP70 family proteins in the cytoplasm and the endoplasmic reticulum (ER) (Itzen et al., 2011; Hedberg and Itzen, 2015; Truttmann and Ploegh, 2017). AMPylation is thought to trap HSP70 in a primed yet transiently disabled state that cannot participate in protein refolding reactions (Preissler et al., 2015). In vitro AMPylation experiments are key to assess the activity, kinetics and specificity of protein AMPylation catalyzed by pro- and eukaryotic enzymes. These simple assays require recombinant AMPylases, target proteins (Rho GTPases, HSP70s), as well as ATP as a nucleotide source. Here, we describe strategies to qualitatively and quantitatively study protein AMPylation in vitro.

PMID- 29170751 TI - Accurate, Streamlined Analysis of mRNA Translation by Sucrose Gradient Fractionation. AB - The efficiency with which proteins are produced from mRNA molecules can vary widely across transcripts, cell types, and cellular states. Methods that accurately assay the translational efficiency of mRNAs are critical to gaining a mechanistic understanding of post-transcriptional gene regulation. One way to measure translational efficiency is to determine the number of ribosomes associated with an mRNA molecule, normalized to the length of the coding sequence. The primary method for this analysis of individual mRNAs is sucrose gradient fractionation, which physically separates mRNAs based on the number of bound ribosomes. Here, we describe a streamlined protocol for accurate analysis of mRNA association with ribosomes. Compared to previous protocols, our method incorporates internal controls and improved buffer conditions that together reduce artifacts caused by non-specific mRNA-ribosome interactions. Moreover, our direct-from-fraction qRT-PCR protocol eliminates the need for RNA purification from gradient fractions, which greatly reduces the amount of hands-on time required and facilitates parallel analysis of multiple conditions or gene targets. Additionally, no phenol waste is generated during the procedure. We initially developed the protocol to investigate the translationally repressed state of the HAC1 mRNA in S. cerevisiae, but we also detail adapted procedures for mammalian cell lines and tissues. PMID- 29170752 TI - Proximal Ligation Assay (PLA) on Lung Tissue and Cultured Macrophages to Demonstrate Protein-protein Interaction. AB - In this protocol, we describe proximal ligation assay (PLA), an antibody-based detection method for protein-protein interaction. This method relies on specific binding of individual primary antibodies to the two putative interacting proteins. The primary antibodies need to have different hosts. The secondary antibodies against the two hosts have complementary oligonucleotide moieties attached to them. If the two antigens are in close proximity (presumably interacting with each other), the complementary oligonucleotides can anneal and fluorescent nucleotides can be incorporated in a single DNA polymerization step. Under a microscope, these reactions appear as punctate fluorescent spots, indicating successful PLA reaction and suggesting protein-protein interaction between the two antigens. PMID- 29170753 TI - The Object Context-place-location Paradigm for Testing Spatial Memory in Mice. AB - This protocol was originally designed to examine long-term spatial memory in PKMzeta knockout (i.e., PKMzeta-null) mice (Tsokas et al., 2016). Our main goal was to test whether the ability of these animals to maintain previously acquired spatial information was sensitive to the type and complexity of the spatial information that needs to be remembered. Accordingly, we modified and combined into a single protocol, three novelty-preference tests, specifically the object in-context, object-in-place and object-in-location tests, adapted from previous studies in rodents (Mumby et al., 2002; Langston and Wood, 2010; Barker and Warburton, 2011). During the training (learning) phase of the procedure, mice are repeatedly exposed to three different environments in which they learn the spatial arrangement of an environment-specific set of non-identical objects. After this learning phase is completed, each mouse receives three different memory tests configured as environment mismatches, in which the previously learned objects-in-space configurations have been modified from the original training situation. The mismatch tests differ in their cognitive demands due to the type of spatial association that is manipulated, specifically evaluating memory for object-context and object-place associations. During each memory test, the time differential spent exploring the novel (misplaced) and familiar objects is computed as an index of novelty discrimination. This index is the behavioral measure of memory recall of the previously acquired spatial associations.

Phase-sensitive nonlinear spectroscopy techniques are widely implemented to explore these dynamics through demodulation of the complex optical signal field into its quadrature components; however, complete reconstruction of the optical response requires measuring both the amplitude and phase of each quadrature, which is often lost in standard detection methods. Here, we implement a heterodyne-detection scheme to fully reconstruct the amplitude and phase response of spectral hole-burning from InAs/GaAs charged quantum dots. We observe an ultra-narrow absorption profile and a corresponding dispersive lineshape of the phase, which reflect the nanosecond optical coherence time of the charged exciton transition. Simultaneously, the measurements are sensitive to electron spin relaxation dynamics on a millisecond timescale, as this manifests as a magnetic-field dependent delay of the amplitude and phase modulation. Appreciable amplitude modulation depth and nonlinear phase shift up to ~0.09*pi radians (16 degrees ) are demonstrated, providing new possibilities for quadrature modulation at faint photon levels with several independent control parameters, including photon number, modulation frequency, detuning, and externally applied fields.

AB - Purpose: Accountable care organizations have the potential to increase the value of healthcare by improving population health and enhanced financial stewardship. How practice context modifies effects on a specialty-focused disease, such as prostate cancer care, has implications for their success. Methods: We performed a retrospective cohort study of newly diagnosed men with prostate cancer between 2012 and 2013 using national Medicare data. Practice affiliation (small single specialty, large single-specialty, multispecialty groups) and accountable care organization alignment were measured at the patient level. Generalized linear multivariable models were fitted to derive adjusted rates of treatment and spending for the 12-month period after diagnosis according to accountable care organization alignment and practice affiliation. Results: Of 15,640 patients with newly diagnosed prostate cancer, 1,100 (7.0%) were aligned with accountable care organizations. Patients in these organizations had similar use of curative treatment to those not in accountable care organizations (71.4% vs. 70.0%, respectively; p=0.33), which did not vary with practice affiliation (p=0.39). Adjusted spending was higher among patients in accountable care organizations ($20,916 vs. $19,773, p=0.03); however, this relationship was independent of the practice affiliation (p=0.90). Higher accountable care organization penetration within a practice was associated with increased spending (p<0.05) but not with treatment (p=0.87). Conclusions: Prostate cancer patients aligned with accountable care organizations had similar rates of treatment, but increased spending, in the year following diagnosis. These findings were similar across practice affiliations. Better specialist engagement by accountable care organizations may be necessary for them to alter practice patterns for specialty care.

AB - Objective: This study evaluated whether providing the Fruits and Vegetables (F/V) required by the Healthy Hunger-Free Kids Act (HHFKA) increased phytochemical/antioxidant content of school lunches. Additionally, the ability of adolescents to apply their nutritional knowledge following participation in a nutrition-focused science-based curriculum was assessed. Methods: Changes in antioxidant/phytochemical content from F/V offered in school lunch menus were analyzed Pre-and Post-HHFKA. Food logs completed by 717 youth aged 10-18 were analyzed for correctly identifying "fighting foods". Results: Significant increases in antioxidant/phytochemical content resulted following implementation of HHFKA (P<0.05). Seventy-five percent [0, 100] of the time students accurately identified "fighting foods" in their one-day in-school food log (n=468). Conclusions and Implications: Creatively incorporating nutrition education into core curriculum, when paired with a supportive built environment that increases F/V access (HHFKA), generates a multilevel intervention promoting F/V consumption among school-aged youth. PMID- 29170757 TI - Human pluripotent stem cell-derived epicardial progenitors can differentiate to endocardial-like endothelial cells. AB - During heart development, epicardial progenitors contribute various cardiac lineages including smooth muscle cells, cardiac fibroblasts, and endothelial cells. However, their specific contribution to the human endothelium has not yet been resolved, at least in part due to the inability to expand and maintain human primary or pluripotent stem cell (hPSC)-derived epicardial cells. Here we first generated CDH5-2A-eGFP knock-in hPSC lines and differentiated them into self renewing WT1+ epicardial cells, which gave rise to endothelial cells upon VEGF treatment in vitro. In addition, we found that the percentage of endothelial cells correlated with WT1 expression in a WT1-2A-eGFP reporter line. The resulting endothelial cells displayed many endocardium-like endothelial cell properties, including high expression levels of endocardial-specific markers, nutrient transporters and well-organized tight junctions. These findings suggest that human epicardial progenitors may have the capacity to form endocardial endothelium during development and have implications for heart regeneration and cardiac tissue engineering.

AB - Introduction: Experiencing the death of a spouse during late life is associated with an increased risk of developing debilitating mental health problems. Healthy lifestyle practices, such as regular exercise, healthy eating, and good sleep hygiene are promising strategies to influence the mental health and associated physical symptoms of late-life spousal bereavement. Objective: This paper describes the design and rationale of an intervention development study addressing selective and indicated prevention of depression, anxiety, and/or complicated grief disorder(s) among adults 60 years and older who are grieving the recent loss (within 8 months) of a spouse or partner. Methods: In Phase I, now complete, we developed and standardized behavioral self-monitoring of daily lifestyle choices via an electronic diary (BSM) and the combined BSM + motivational interviewing-based lifestyle coaching (BSM+MI) to be administered to participants grieving the loss of loved one. In Phase II, we have been implementing the interventions in a randomized controlled trial and addressing challenges related to recruitment. Randomization is to one of three cells: BSM, BSM+MI, or an enhanced usual care condition. Discussion: Several challenges in implementing our lifestyle interventions to older widow(er)s who are at risk for common mental disorders have been identified. Direct outreach to hospice organizations is an effective way to identify older adults in the early months following spousal death. Results from study may advance the field of grief support and promote a healthy adaptation to widowhood. PMID- 29170759 TI - Autism, Attention, and Alpha Oscillations: An Electrophysiological Study of Attentional Capture. AB - Background: Autism spectrum disorder (ASD) is associated with deficits in adaptively orienting attention to behaviorally-relevant information. Neural oscillatory activity plays a key role in brain function and provides a high resolution temporal marker of attention dynamics. Alpha band (8-12 Hz) activity is associated with both selecting task-relevant stimuli and filtering task irrelevant information. Methods: The present study used electroencephalography (EEG) to examine alpha-band oscillatory activity associated with attentional capture in nineteen children with ASD and twenty-one age- and IQ-matched typically developing (TD) children. Participants completed a rapid serial visual presentation paradigm designed to investigate responses to behaviorally-relevant targets and contingent attention capture by task-irrelevant distractors, which either did or did not share a behaviorally-relevant feature. Participants also completed six minutes of eyes-open resting EEG. Results: In contrast to their TD peers, children with ASD did not evidence posterior alpha desynchronization to behaviorally-relevant targets. Additionally, reduced target-related desynchronization and poorer target detection were associated with increased ASD symptomatology. TD children also showed behavioral and electrophysiological evidence of contingent attention capture, whereas children with ASD showed no behavioral facilitation or alpha desynchronization to distractors that shared a task-relevant feature. Lastly, children with ASD had significantly decreased resting alpha power, and for all participants increased resting alpha levels were associated with greater task-related alpha desynchronization. Conclusions: These results suggest that in ASD under-responsivity and impairments in orienting to salient events within their environment are reflected by atypical EEG oscillatory neurodynamics, which may signify atypical arousal levels and/or an excitatory/inhibitory imbalance. PMID- 29170760 TI - The long reach of early adversity: Parenting, stress, and neural pathways to antisocial behavior in adulthood. AB - Background: Early life adversities including harsh parenting, maternal depression, neighborhood deprivation, and low family economic resources are more prevalent in low-income urban environments and are potent predictors of psychopathology, including, for boys, antisocial behavior (AB). However, little research has examined how these stressful experiences alter later neural function. Moreover, identifying genetic markers of greater susceptibility to adversity is critical to understanding biopsychosocial pathways from early adversity to later psychopathology. Methods: Within a sample of 310 low-income boys followed from age 1.5 to 20, multimethod assessments of adversities were examined at age 2 and age 12. At age 20, amygdala reactivity to emotional facial expressions was assessed using fMRI, and symptoms of Antisocial Personality Disorder were assessed via structured clinical interview. Genetic variability in cortisol signaling (CRHR1) was examined as a moderator of pathways to amygdala reactivity. Results: Observed parenting and neighborhood deprivation at age 2 each uniquely predicted amygdala reactivity to emotional faces at age 20 over and above other adversities measured at multiple developmental periods. Harsher parenting and greater neighborhood deprivation in toddlerhood predicted clinically-significant symptoms of AB via less amygdala reactivity to fearful facial expressions and this pathway was moderated by genetic variation in CRHR1. Conclusions: These results elucidate a pathway linking early adversity to less amygdala reactivity to social signals of interpersonal distress 18 years later, which in turn increased risk for serious AB. Moreover, these findings suggest a genetic marker of youth more susceptible to adversity.

AB - Latex allergy confounded by IV infiltration presents a serious problem for pediatric patients. If unrecognized, it can lead to serious neurologic deficits, loss of limb mobility, compartment syndrome, and ultimately lasting disability. Appropriate early recognition can prevent progression to these devastating outcomes. In this case report, we present an infant with IV infiltration and latex allergy. The case is used to highlight important clinical diagnostic criteria, treatment approaches, and how to prevent detrimental outcomes. We provide a detailed review of the literature and highlight the key teaching points in a reader-friendly reference table. PMID- 29170762 TI - Clinical Utility of CLIA-Grade AR-V7 Testing in Patients With Metastatic Castration-Resistant Prostate Cancer. AB - Purpose: A splice variant of the androgen receptor, AR-V7, confers resistance to AR-targeted therapies (ATTs) but not taxane chemotherapies in patients with metastatic castration-resistant prostate cancer. Since August 2015, a clinical grade assay to detect AR-V7 messenger RNA expression in circulating tumors cells (CTCs) has been available to providers through a Clinical Laboratory Improvement Amendments-certified laboratory at Johns Hopkins University. Methods: We contacted ordering providers of the first 150 consecutive tests by using a questionnaire-based survey to determine how the results of AR-V7 testing were used to influence clinical practice. Results: In all, 142 (95%) of 150 questionnaires were completed by 38 providers from 29 sites across the United States and Canada. AR-V7 test results were reported either as CTC- (28%), CTC+/AR V7- (30%), or CTC+/AR-V7+ (42%). Prevalence of AR-V7 detection increased with prior exposure to ATTs (abiraterone and enzalutamide naive, 22%; after abiraterone or enzalutamide, 35%; after abiraterone and enzalutamide, 43%). Overall, management was affected by AR-V7 testing in 53% of the patients and even more often with CTC+/AR-V7+ results. AR-V7+ patients were commonly switched from ATT to taxane chemotherapy (43%) or were offered a clinical trial (43%); management remained unchanged in only 14% of these patients. Overall, patients who had a change in management on the basis of AR-V7 testing were significantly more likely to achieve a physician-reported 50% decline in prostate-specific antigen response on next-line therapy than those who did not change treatment (54% v 31%; P = .015). Conclusion: Providers used AR-V7 testing to influence clinical decision making more often than not. Physicians reported thatmenwithAR V7+results had the most treatment changes, and such men were preferentially managed with taxane therapy or offered a clinical trial, which may have improved outcomes.

AB - The growing number of persons surviving to age 100 years and beyond raises questions about the shape of mortality trajectories at exceptionally high ages, and this problem may become significant for actuaries in the near future. However, such studies are scarce because of the difficulties in obtaining reliable age estimates at exceptionally high ages. The current view about mortality beyond age 110 years suggests that death rates do not grow with age and are virtually flat. The same assumption is made in the new actuarial VBT tables. In this paper, we test the hypothesis that the mortality of supercentenarians (persons living 110+ years) is constant and does not grow with age, and we analyze mortality trajectories at these exceptionally high ages. Death records of supercentenarians were taken from the International Database on Longevity (IDL). All ages of supercentenarians in the database were subjected to careful validation. We used IDL records for persons belonging to extinct birth cohorts (born before 1895) since the last deaths in IDL were observed in 2007. We also compared our results based on IDL data with a more contemporary database maintained by the Gerontology Research Group (GRG). First we attempted to replicate findings by Gampe (2010), who analyzed IDL data and came to the conclusion that "human mortality after age 110 is flat." We split IDL data into two groups: cohorts born before 1885 and cohorts born in 1885 and later. Hazard rate estimates were conducted using the standard procedure available in Stata software. We found that mortality in both groups grows with age, although in older cohorts, growth was slower compared with more recent cohorts and not statistically significant. Mortality analysis of more numerous 1884-1894 birth cohort with the Akaike goodness-of-fit criterion showed better fit for the Gompertz model than for the exponential model (flat mortality). Mortality analyses with GRG data produced similar results. The remaining life expectancy for the 1884-1894 birth cohort demonstrates rapid decline with age. This decline is similar to the computer-simulated trajectory expected for the Gompertz model, rather than the extremely slow decline in the case of the exponential model. These results demonstrate that hazard rates after age 110 years do not stay constant and suggest that mortality deceleration at older ages is not a universal phenomenon. These findings may represent a challenge to the existing theories of aging and longevity, which predict constant mortality in the late stages of life. One possibility for reconciliation of the observed phenomenon and the existing theoretical consideration is a possibility of mortality deceleration and mortality plateau at very high yet unobservable ages. PMID- 29170765 TI - Historical Evolution of Old-Age Mortality and New Approaches to Mortality Forecasting. AB - Knowledge of future mortality levels and trends is important for actuarial practice but poses a challenge to actuaries and demographers. The Lee-Carter method, currently used for mortality forecasting, is based on the assumption that the historical evolution of mortality at all age groups is driven by one factor only. This approach cannot capture an additive manner of mortality decline observed before the 1960s. To overcome the limitation of the one-factor model of mortality and to determine the true number of factors underlying mortality changes over time, we suggest a new approach to mortality analysis and forecasting based on the method of latent variable analysis. The basic assumption of this approach is that most variation in mortality rates over time is a manifestation of a small number of latent variables, variation in which gives rise to the observed mortality patterns. To extract major components of mortality variation, we apply factor analysis to mortality changes in developed countries over the period of 1900-2014. Factor analysis of time series of age-specific death rates in 12 developed countries (data taken from the Human Mortality Database) identified two factors capable of explaining almost 94 to 99 percent of the variance in the temporal changes of adult death rates at ages 25 to 85 years. Analysis of these two factors reveals that the first factor is a "young-age" or background factor with high factor loadings at ages 30 to 45 years. The second factor can be called an "oldage" or senescent factor because of high factor loadings at ages 65 to 85 years. It was found that the senescent factor was relatively stable in the past but now is rapidly declining for both men and women. The decline of the senescent factor is faster for men, although in most countries, it started almost 30 years later. Factor analysis of time series of age-specific death rates conducted for the oldest-old ages (65 to 100 years) found two factors explaining variation of mortality at extremely old ages in the United States. The first factor is comparable to the senescent factor found for adult mortality. The second factor, however, is specific to extreme old ages (96 to 100 years) and shows peaks in 1960 and 2000. Although mortality below 90 to 95 years shows a steady decline with time driven by the senescent factor, mortality of centenarians does not decline and remains relatively stable. The approach suggested in this paper has several advantages. First, it is able to determine the total number of independent factors affecting mortality changes over time. Second, this approach allows researchers to determine the time interval in which underlying factors remain stable or undergo rapid changes. Most methods of mortality projections are not able to identify the best base period for mortality projections, attempting to use the longest-possible time period instead. We observe that the senescent factor of mortality continues to decline, and this decline does not demonstrate any indications of slowing down. At the same time, mortality of centenarians does not decline and remains stable. The lack of mortality decline at extremely old ages may diminish anticipated longevity gains in the future.

AB - Throughout a patient's stay in the Intensive Care Unit (ICU), accurate measurement of patient mobility, as part of routine care, is helpful in understanding the harmful effects of bedrest [1]. However, mobility is typically measured through observation by a trained and dedicated observer, which is extremely limiting. In this work, we present a video-based automated mobility measurement system called NIMS: Non-Invasive Mobility Sensor . Our main contributions are: (1) a novel multi-person tracking methodology designed for complex environments with occlusion and pose variations, and (2) an application of human-activity attributes in a clinical setting. We demonstrate NIMS on data collected from an active patient room in an adult ICU and show a high inter-rater reliability using a weighted Kappa statistic of 0.86 for automatic prediction of the highest level of patient mobility as compared to clinical experts. PMID- 29170767 TI - Robust indirect band gap and anisotropy of optical absorption in B-doped phosphorene. AB - A traditional doping technique plays an important role in the band structure engineering of two-dimensional nanostructures. Since electron interaction is changed by doping, the optical and electrochemical properties could also be significantly tuned. In this study, density functional theory calculations have been employed to explore the structural stability, and electronic and optical properties of B-doped phosphorene. The results show that all B-doped phosphorenes are stable with a relatively low binding energy. Of particular interest is that these B-doped systems exhibit an indirect band gap, which is distinct from the direct one of pure phosphorene. Despite the different concentrations and configurations of B dopants, such indirect band gaps are robust. The screened hybrid density functional HSE06 predicts that the band gap of B-doped phosphorene is slightly smaller than that of pure phosphorene. Spatial charge distributions at the valence band maximum (VBM) and the conduction band minimum (CBM) are analyzed to understand the features of an indirect band gap. By comparison with pure phosphorene, B-doped phosphorenes exhibit strong anisotropy and intensity of optical absorption. Moreover, B dopants could enhance the stability of Li adsorption on phosphorene with less sacrifice of the Li diffusion rate. Our results suggest that B-doping is an effective way of tuning the band gap, enhancing the intensity of optical absorption and improving the performances of Li adsorption, which could promote potential applications in novel optical devices and lithium-ion batteries. PMID- 29170768 TI - Counterion effects on the ultrafast dynamics of charge-transfer-to-solvent electrons. AB - We performed femtosecond transient absorption (TA) experiments to monitor the solvation dynamics of charge-transfer-to-solvent (CTTS) electrons originating from UV photoexcitation of ammoniated iodide in close proximity to the counterions. Solutions of KI were prepared in liquid ammonia and TA experiments were carried out at different temperatures and densities, along the liquid-gas coexistence curve of the fluid. The results complement previous femtosecond TA work by P. Vohringer's group in neat ammonia via multiphoton ionization. The dynamics of CTTS-detached electrons in ammonia was found to be strongly affected by ion pairing. Geminate recombination time constants as well as escape probabilities were determined from the measured temporal profiles and analysed as a function of the medium density. A fast unresolved (tau < 250 fs) increase of absorption related to the creation/thermalization of solvated electron species was followed by two decay components: one with a characteristic time around 10 ps, and a slower one that remains active for hundreds of picoseconds. While the first process is attributed to an early recombination of (I, e-) pairs, the second decay and its asymptote reflects the effect of the K+ counterion on the geminate recombination dynamics, rate and yield. The cation basically acts as an electron anchor that restricts the ejection distance, leading to solvent separated counterion-electron species. The formation of (K+, NH3, e-) pairs close to the parent iodine atom brings the electron escape probability to very low values. Transient spectra of the electron species have also been estimated as a function of time by probing the temporal profiles at different wavelengths.

AB - The precision synthesis and self-assembly of amphiphilic copolypeptides containing a recombinant elastin-like polypeptide (ELP) block used as a macroinitiator for the ring opening polymerization (ROP) of gamma-benzyl-l glutamate (gamma-BLG NCA) are herein presented. The molecular weight of the resulting PBLG-b-ELP block copolypeptides was precisely controlled without the use of complex initiator or demanding experimental setup. Diblock copolypeptides were obtained with an excellent control of the polymerization highlighted by the dispersity below 1.04. These amphiphilic hybrid synthetic/recombinant copolypeptides were self-assembled in water and the nanoparticles obtained were characterized by a combination of dynamic light scattering and electron microscopy. A variety of morphologies, namely polymersomes, inter-connected worm like micelles and spherical micelles, were evidenced depending on the hydrophilic ratio of the diblocks as well as the self-assembly procedure.

PMID- 29170772 TI - A kinetic study of the gas-phase reactions of 1-methylsilacyclobutane in hot wire chemical vapor deposition. AB - The reaction kinetics of the decomposition of 1-methylsilacyclobutane (MSCB) in a hot wire chemical vapor deposition (HWCVD) reactor was investigated. The stable reaction products were monitored using vacuum ultraviolet laser single photon ionization in tandem with time-of-flight mass spectrometry. Steady-state approximation was used to determine the rate constants of three individual decomposition pathways of MSCB, i.e., cycloreversion to form ethene and methylsilene (R1), ring opening to form propene and methylsilylene (R2), and exocyclic Si-CH3 bond cleavage to form CH3 radicals (R3). The activation energies (Ea) for R2 and R3 in a HWCVD reactor were determined to be 86.6 kJ mol-1 and 106 kJ mol-1, respectively. The fact that these Ea values are close to those obtained for the MSCB decomposition on metal surfaces under collision-free conditions indicates that the heterogeneous reactions on the hot wire surface govern the gas phase reaction kinetics in the HWCVD reactor. In addition, the Ea values obtained from a theoretical study of the decomposition kinetics using ab initio calculations at the CCSD(T)/6-311++G(3d,2p)//MP2/6-311++G(d,p) level were 62.9 kcal mol-1 (i.e., 263 kJ mol-1), 62.0 kcal mol-1 (i.e., 259 kJ mol-1), and 86.2 kcal mol-1 (i.e., 361 kJ mol-1) for R1, R2, and R3, respectively. The much lower experimental Ea values compared with those from the theoretical calculations clearly suggest that the tungsten filament in the HWCVD reactor catalyzed the decomposition. PMID- 29170771 TI - A fluorescent combinatorial logic gate with Na+, H+-enabled OR and H+-driven low medium-high ternary logic functions. AB - A novel fluorescent molecular logic gate with a 'fluorophore-spacer1-receptor1 spacer2-receptor2' format is demonstrated in 1 : 1 (v/v) methanol/water. The molecule consists of an anthracene fluorophore, and tertiary alkyl amine and N-(2 methoxyphenyl)aza-15-crown-5 ether receptors. In the presence of threshold concentrations of H+ and Na+, the molecule switches 'on' as an AND logic gate with a fluorescence quantum yield of 0.21 with proton and sodium binding constants of log betaH+ = 9.0 and log betaNa+ = 3.2, respectively. At higher proton levels, protonation also occurs at the anilinic nitrogen atom ether with a log betaH+ = 4.2, which allows for Na+, H+-enabled OR (OR + AND circuit) and H+ driven ternary logic functions. The reported molecule is compared and contrasted to classic anthracene-based Na+ and H+ logic gates. We propose that such logic based molecules could be useful tools for probing the vicinity of Na+, H+ antiporters in biological systems. PMID- 29170773 TI - Solvatochromism in perylene diimides; experiment and theory. AB - We report an experimental and computational investigation into the solvatochromism of a perylene diimide derivative. The alkyl swallowtail substituents allowed solubility in many solvents of widely differing polarity, with a complicated resultant behaviour, illustrating both negative and positive solvatochromism as a function of dielectric constant. Luminescence quantum yield and optical absorption linewidth displayed an inverse correlation, indicating varying degrees of intermolecular aggregation, and a remarkably similar trend was found between the peak absorption wavelength and the solvent boiling point, illustrating the dependency of aggregation on the solvent interactions. These outline trends may be parameterised by an empirically derived dimensionless quantity, as a tool to be used in more sophisticated future models of solvatochromism in small molecule chromophores. PMID- 29170774 TI - A modular approach towards functionalized highly stable self-complementary quadruple hydrogen bonded systems. AB - Self-complementary quadruple hydrogen bonded systems have shown potential as key building blocks for developing various supramolecular polymers. Opportunities for the introduction of multiple functionalities would further augment, in principle, their application potential. Herein, we report a novel modular approach to simultaneously introduce two closely aligned side chains into AADD-type self complementary quadruple hydrogen-bonding systems. Dithiane-tethered ureidopyrimidinone has been used as a reactive intermediate to efficiently attach closely aligned side chains by simply reacting with amines to form highly stable molecular duplexes. These duplexes featuring AADD-type arrays of hydrogen bonding codes are highly stable in non-polar solvents (Kdim > 1.9 * 107 M-1 in CDCl3) as well as in polar solvents (Kdim > 105 in 10% DMSO-d6/CDCl3). Another notable feature of these self-assembling systems is their insensitivity to prototropy related issues owing to their prototropic degeneracy, which will enhance their application potential in supramolecular chemistry.

AB - Magnetite is a conversion anode material displaying multi-electron transfer during lithiation and delithiation. The solid electrolyte interphase (SEI) on magnetite, Fe3O4, electrodes for lithium ion batteries was deliberately modified through the use of fluoroethylene carbonate (FEC) electrolyte additive, improving both capacity retention and rate capability. Analysis showed reduction of FEC at higher voltage compared to non-fluorinated solvents with formation of a modified lithium flouride containing electrode surface. PMID- 29170780 TI - The absorption spectrum of cis-azobenzene. AB - Azobenzene is a prototypical photochromic molecule existing in two isomeric forms, which has numerous photochemical applications that rely on a precise knowledge of the molar absorption coefficients (epsilon). Careful analysis revealed that the previously reported absorption spectra of the "pure" isomers were in fact mutually contaminated by small amounts of the other isomer. Therefore, the absorption spectra of both trans- and cis-azobenzene in methanol were re-determined at temperatures of 5-45 degrees C. The thermodynamically more stable trans-azobenzene was prepared by warming the solution in the dark. To obtain the spectrum of cis-azobenzene three methods were used, which gave consistent results within the limits of error. The method based on the subtraction of derivative spectra coupled with a global analysis of the spectra recorded during thermal cis-trans isomerization is shown to give slightly more reliable results than the method using isomeric ratios determined by 1H-NMR. The described methods are readily generalizable to other azobenzene derivatives and to other photochromic systems. The practical implication of the re-determined epsilon values is demonstrated by a very high precision of spectrophotometric species analysis in azobenzene isomeric mixtures. The new epsilon values imply that the previously reported quantum yields must be revised.

AB - A structural, spectroscopic and computational study of a series of oximes was undertaken to investigate how geometric and structural changes relevant to the reaction coordinate for the Beckmann reaction (normal Beckmann) and Beckmann fragmentation (abnormal Beckmann) manifest in the ground state. X-ray structures of a range of oximes derived from dihydrolevoglucosan (CyreneTM; which undergoes the abnormal Beckmann reaction), in which the oxygen substituent was systematically varied were determined. As the electron demand of the OR group increased, the major structural changes included lengthening of the N-OR bond distance, and a decrease in the magnitude of the C2[double bond, length as m dash]N-O bond angle, consistent with the changes seen for cyclohexanone oximes, which undergo the normal Beckmann reaction. However, unique to the Cyrene oximes, an increase in the length of the fissile C1-C2 bond was observed, which correlated with a decrease in the 13C-13C 1-bond coupling constants as the electron demand of the OR substituent increased. Computational studies of Cyrene and cyclohexanone oximes using Natural Bond Orbital analysis support an electronic structure involving n(O) -> sigma*C1-C2 and sigmaC1-C2 -> sigma*N-O localized orbital interactions.

AB - Kidney-specific delivery is critically important for the treatment of renal fibrosis with drugs such as salvianolic acid B (Sal B). Here we report a kidney specific nanocomplex formed by the coordination-driven assembly of catechol modified low molecular weight chitosan (HCA-Chi), calcium ions and Sal B. The prepared HCA-Chi-Ca-Sal B (HChi-Ca-Sal B) nanocomplex reversed the TGF-beta1 induced epithelial-mesenchymal transition (EMT) in HK-2 cells. In vivo imaging demonstrated a kidney-specific biodistribution of the nanocomplex. The anti fibrosis effect of HChi-Ca-Sal B was tested in a mouse model of unilateral ureteral obstruction (UUO). Significant attenuation of the morphological lesions and the levels of extracellular matrix (ECM) proteins in the tubulointerstitium was observed in mice treated with HChi-Ca-Sal B, suggesting that the nanocomplex was able to prevent fibrosis better than the treatment with free Sal B. It was concluded that the HChi-Ca-Sal B nanocomplex showed a specific renal targeting capacity and could be utilized to enhance Sal B delivery for treating renal fibrosis.

AB - Anticancer metallodrugs based on ruthenium and osmium are among the most investigated and advanced non-platinum metallodrugs. Inorganic drug discovery with these agents has undergone considerable advances over the past two decades and has currently two representatives in active clinical trials. As many ruthenium and osmium metallodrugs are prodrugs, a key question to be addressed is how the molecular reactivity of such metal-based therapeutics dictates the selectivity and the type of interaction with molecular targets. Within this frame, this review introduces the field by the examples of the most advanced ruthenium lead structures. Then, global structure-activity relationships are discussed for ruthenium and osmium metallodrugs with respect to in vitro antiproliferative/cytotoxic activity and in vivo tumor-inhibiting properties, as well as pharmacokinetics. Determining and validating global mechanisms of action and molecular targets are still major current challenges. Moreover, significant efforts must be invested in screening in vivo tumor models that mimic human pathophysiology to increase the predictability for successful preclinical and clinical development of ruthenium and osmium metallodrugs.

PMID- 29170785 TI - Amplification or cancellation of Fano resonance and quantum confinement induced asymmetries in Raman line-shapes. AB - Fano resonance is reported here to be playing a dual role by amplifying or compensating for the quantum confinement effect induced asymmetry in Raman line shape in silicon (Si) nanowires (NWs) obtained from heavily doped n- and p-type Si wafers respectively. The compensatory nature results in a near symmetric Raman line-shape from heavily doped p-type Si nanowires (NWs) as both the components almost cancel each other. On the other hand, the expected asymmetry, rather with enhancement, has been observed from heavily doped n-type SiNWs. Such a system (p- & n-) dependent Raman line-shape study has been carried out by theoretical line shape analysis followed by experimental validation through suitably designed experiments. A dual role of Fano resonance in n- and p-type nano systems has been observed to modulate Raman spectra differently and reconcile accordingly to enhance and cease the Raman spectral asymmetry respectively. The present analysis will enable one to be more careful while analyzing a symmetric Raman line-shape from semiconductor nanostructures. PMID- 29170787 TI - Synthesis, computational, and spectroscopic analysis of tunable highly fluorescent BN-1,2-azaborine derivatives containing the N-BOH moiety. AB - Nine new polycyclic aromatic BN-1,2-azaborine analogues containing the N-BOH moiety were synthesized using a convenient two-step, one-pot procedure. Characterization of the prepared compounds show the luminescence wavelength and the quantum yields of the azaborines were tunable by controlling the power and location of the donor and acceptor substituents on the chromophore. UV-visible spectroscopy and density functional theory (DFT) computations revealed that the addition of electron-donating moieties to the isoindolinone hemisphere raised the energy of the HOMO, resulting in the reduction of the HOMO-LUMO gap. The addition of an electron-accepting moiety to the isoindolinone hemisphere and an electron donating group to the boronic acid hemisphere decreased the HOMO-LUMO gap considerably, leading to emission properties from partial intramolecular charge transfer (ICT) states. The combined effect of an acceptor on the isoindolinone side and a donor on the boronic acid side (strong acceptor-pi-donor) gave the most red-shifted absorption. The polycyclic aromatic BN-1,2-azaborines emitted strong fluorescence in solution and in the solid-state with the largest red shifted emission at 640 nm and a Stokes shift of Deltalambda = 218 nm, or Deltanu = 8070 cm-1. PMID- 29170788 TI - [Incontinence after radical prostatectomy : Male Sling or "best option" first?] AB - Postprostatectomy incontinence (PPI) is a rare complication of radical prostatectomy, and it may lead to severe limitations for the patient and loss of quality of life. Several different surgical options for the therapy of PPI are available and may be chosen depending on severity of incontinence, residual urethral sphincter function, and previous history of radiotherapy. Alternatives to artificial urinary sphincters which over the last few decades have represented the gold standard for treatment of PPI are fixed slings and adjustable devices. In cases of mild or moderate incontinence, male slings can be used. Adjustable devices can also be adopted in irradiated patient with good results. Artificial urinary sphincters represent the ideal option in case of severe incontinence. Absolute contraindications for the implant of this device are impaired dexterity and cognitive capacity of the patients that may make use of the pump difficult. One type of therapy for all patients does not exist and must be individually determined. It is influenced by the grade of incontinence, the anatomical conditions, and the patient's expectations. Thus, appropriate counselling is mandatory. A common opinion is that these devices are direct competitors in the treatment of PPI. In reality, these devices are completely different surgical methods that rely on different principles and therefore have different indications.

AB - The inherent heterogeneity in cell populations has become of great interest and importance as analytical techniques have improved over the past decades. With the advent of personalized medicine, understanding the impact of this heterogeneity has become an important challenge for the research community. Many different microfluidic approaches with varying levels of throughput and resolution exist to study single cell activity. In this review, we take a broad view of the recent microfluidic developments in single cell analysis based on microwell, microchamber, and droplet platforms. We cover physical, chemical, and molecular biology approaches for cellular and molecular analysis including newly emerging genome-wide analysis. PMID- 29170791 TI - Trauma-induced coagulopathy upon emergency room arrival: still a significant problem despite increased awareness and management? AB - PURPOSE: Over the last decade, the pivotal role of trauma-induced coagulopathy has been described and principal drivers have been identified. We hypothesized that the increased knowledge on coagulopathy of trauma would translate into a more cautious treatment, and therefore, into a reduced overall incidence rate of coagulopathy upon ER admission. PATIENTS AND METHODS: Between 2002 and 2013, 61,212 trauma patients derived from the TraumaRegister DGU(r) had a full record of coagulation parameters and were assessed for the presence of coagulopathy. Coagulopathy was defined by a Quick's value < 70% and/or platelet counts < 100,000/ul upon ER admission. For each year, the incidence of coagulopathy, the amount of pre-hospital administered i.v.-fluids and transfusion requirements were assessed. RESULTS: Coagulopathy upon ER admission was present in 24.5% of all trauma patients. Within the years 2002-2013, the annual incidence of coagulopathy decreased from 35 to 20%. Even in most severely injured patients (ISS > 50), the incidence of coagulopathy was reduced by 7%. Regardless of the injury severity, the amount of pre-hospital i.v.-fluids declined during the observed period by 51%. Simultaneously, morbidity and mortality of severely injured patients were on the decrease. CONCLUSION: During the 12 years observed, a substantial decline of coagulopathy has been observed. This was paralleled by a significant decrease of i.v.-fluids administered in the pre-hospital treatment. The reduced presence of coagulopathy translated into decreased transfusion requirements and mortality. Nevertheless, especially in the most severely injured patients, posttraumatic coagulopathy remains a frequent and life-threatening syndrome. PMID- 29170790 TI - A multiple near isogenic line (multi-NIL) RNA-seq approach to identify candidate genes underpinning QTL. AB - KEY MESSAGE: This study demonstrates how identification of genes underpinning disease-resistance QTL based on differential expression and SNPs can be improved by performing transcriptomic analysis on multiple near isogenic lines. Transcriptomic analysis has been widely used to understand the genetic basis of a trait of interest by comparing genotypes with contrasting phenotypes. However, these approaches identify such large sets of differentially expressed genes that it proves difficult to isolate which genes underpin the phenotype of interest. This study tests whether using multiple near isogenic lines (NILs) can improve the resolution of RNA-seq-based approaches to identify genes underpinning disease resistance QTL. A set of NILs for a major effect Fusarium crown rot-resistance QTL in barley on the 4HL chromosome arm were analysed under Fusarium crown rot using RNA-seq. Differential gene expression and single nucleotide polymorphism detection analyses reduced the number of putative candidates from thousands within individual NIL pairs to only one hundred and two genes, which were differentially expressed or contained SNPs in common across NIL pairs and occurred on 4HL. Our findings support the value of performing RNA-seq analysis using multiple NILs to remove genetic background effects. The enrichment analyses indicated conserved differences in the response to infection between resistant and sensitive isolines suggesting that sensitive isolines are impaired in systemic defence response to Fusarium pseudograminearum. PMID- 29170789 TI - CREBBP and p300 lysine acetyl transferases in the DNA damage response. AB - The CREB-binding protein (CREBBP, or in short CBP) and p300 are lysine (K) acetyl transferases (KAT) belonging to the KAT3 family of proteins known to modify histones, as well as non-histone proteins, thereby regulating chromatin accessibility and transcription. Previous studies have indicated a tumor suppressor function for these enzymes. Recently, they have been found to acetylate key factors involved in DNA replication, and in different DNA repair processes, such as base excision repair, nucleotide excision repair, and non homologous end joining. The growing list of CBP/p300 substrates now includes factors involved in DNA damage signaling, and in other pathways of the DNA damage response (DDR). This review will focus on the role of CBP and p300 in the acetylation of DDR proteins, and will discuss how this post-translational modification influences their functions at different levels, including catalytic activity, DNA binding, nuclear localization, and protein turnover. In addition, we will exemplify how these functions may be necessary to efficiently coordinate the spatio-temporal response to DNA damage. CBP and p300 may contribute to genome stability by fine-tuning the functions of DNA damage signaling and DNA repair factors, thereby expanding their role as tumor suppressors. PMID- 29170792 TI - Prospective comparison among three intrarectal anesthetic treatments combined with periprostatic nerve block during transrectal ultrasonography-guided prostate biopsy. AB - BACKGROUND: Recent trends in prostate biopsy analgesia suggest a combination anesthetic to provide better pain relief than periprostatic nerve block (PPNB) alone. This study aimed to demonstrate the efficacy and safety of three intrarectal local anesthesia (IRLA) combined with PPNB in patients undergoing transrectal ultrasonography (TRUS)-guided prostate biopsy. METHODS: In this prospective, randomized study, 120 prostate biopsy patients were equally divided into four IRLA groups: group 1 (placebo) received simple lubrication; group 2 received 2% lidocaine gel; group 3 received 100 mg indomethacin suppository and group 4 received 5% prilocaine/lidocaine (EMLA) cream. PPNB with 2% lidocaine was applied in all groups. A ten-point visual analog scale evaluated both pain associated with the probe insertion and pain associated with prostate sampling. Adverse effects or complications due to anesthesia during and after the procedure were documented. RESULTS: Compared with group 1, groups 3 and 4 had significantly lower pain scores at both probe insertion and prostate sampling while group 2 showed no significant differences at both pain scores. Moreover, group 4 showed significantly lower pain scores at probe insertion compared to group 3, while no significant difference was observed at prostate sampling. Mild complications were observed in all groups with no significant difference in the incidence of complications between groups. CONCLUSION: Intrarectal application of EMLA cream is a more efficient pain reduction than either 2% lidocaine gel or 100 mg indomethacin suppository when applied combined with PPNB. This combination represents an effective option of pain relief for patients undergoing TRUS-guided prostate biopsy.

AB - PURPOSES: Our study aims to enhance the accuracy of the clinical diagnosis in patients with vaginal mesh extrusion following transvaginal mesh placement for pelvic organ prolapse using significant clinical parameters and risk factors. METHODS: All patients who underwent vaginal mesh removal were retrospectively reviewed from January 2000 to May 2014. Eligible patients were divided into two groups according to the presence of vaginal mesh extrusion. RESULTS: A total of 862 patients, 798 were included. 357 (44.7%) had evidence of vaginal mesh extrusion, and 441 (55.3%) had no evidence of vaginal mesh extrusion. The mean age of the vaginal mesh extrusion group was slightly higher than in the group without vaginal mesh extrusion (58.7 +/- 11.2 vs. 56.4 +/- 11.5, respectively; p = 0.002). From multivariate analysis, the significant clinical correlations for vaginal mesh extrusion were vaginal bleeding [60 (16.9) vs. 14 (3.2%), p < 0.001], hispareunia [48 (13.5) vs. 15 (3.4%), OR = 4.163, p < 0.001], and vaginal discharge [45 (12.6) vs. 18 (4.1%), p = 0.001]. The risk factors were multiple mesh implantations [218 (67.06) vs. 175 (39.68%), p < 0.001] and menopause [314 (88) vs. 364 (82.7%), p = 0.145]. Demographic data, including BMI, sexual activity, vaginal atrophy, both local and systemic hormonal use, smoking status, and hysterectomy status, were not significantly different, as well as the clinical symptoms including dyspareunia, vaginal infection, and symptomatic vaginal bulge. CONCLUSIONS: Vaginal bleeding, hispareunia, and vaginal discharge were the most significant clinical predictors for raising suspicion of vaginal mesh extrusion. Multiple mesh implantations were a significant risk factor for extrusion. PMID- 29170794 TI - Three-dimensional microCT imaging of murine embryonic development from immediate post-implantation to organogenesis: application for phenotyping analysis of early embryonic lethality in mutant animals. AB - In this work, we applied three-dimensional microCT imaging to study murine embryogenesis in the range from immediate post-implantation period (embryonic day 5.5) to mid-gestation (embryonic day 12.5) with the resolution up to 1.4 um/voxel. Also, we introduce an imaging procedure for non-invasive volumetric estimation of an entire litter of embryos within the maternal uterine structures. This method allows for an accurate, detailed and systematic morphometric analysis of both embryonic and extra-embryonic components during embryogenesis. Three dimensional imaging of unperturbed embryos was performed to visualize the egg cylinder, primitive streak, gastrulation and early organogenesis stages of murine development in the C57Bl6/N mouse reference strain. Further, we applied our microCT imaging protocol to determine the earliest point when embryonic development is arrested in a mouse line with knockout for tRNA splicing endonuclease subunit Tsen54 gene. Our analysis determined that the embryonic development in Tsen54 null embryos does not proceed beyond implantation. We demonstrated that application of microCT imaging to entire litter of non perturbed embryos greatly facilitate studies to unravel gene function during early embryogenesis and to determine the precise point at which embryonic development is arrested in mutant animals. The described method is inexpensive, does not require lengthy embryos dissection and can be applicable for detailed analysis of mutant mice at laboratory scale as well as for high-throughput projects.

PMID- 29170796 TI - Factors Affecting Element Concentrations in Eggshells of Three Sympatrically Nesting Waterbirds in Northern Poland. AB - Avian eggshells are convenient samples in biomonitoring studies, because they are easily accessible, especially from colonially or semicolonially breeding birds. In the present study, concentrations of 17 elements, including heavy metals and essential elements in post-hatch eggshells, were compared among three species of waterbirds of differing strategies for gaining reserves for egg production and diet: mallard, Anas platyrhynchos (ML, a capital breeder, mainly herbivorous), common tern, Sterna hirundo (CT, an income breeder, piscivorous) and black-headed gull, Chroicocephalus ridibundus (BHG, mixed strategy, omnivorous) and breeding sympatrically in three sites in North Poland. Analyses revealed that Fe, Zn, and Cu levels differed the most in the studied species, which may be explained by various contributions of fish, aquatic plants, and soil invertebrates in their diets. Generally, the studied species' eggshells accumulated amounts of elements comparable to those reported for other waterbirds without putting the growth and development of the embryo at risk. The only exception was very high levels of Cr in ML and CT, which may be explained by their foraging on aquatic organisms in waterbodies polluted by this element. Intersite differences in eggshell concentrations of Ni, Sr, Hg and Cr in CT (an income breeder) may be explained by the influence of local pollution sources (small factories, polluted river).

AB - A new, fast, easy to handle, and environmentally friendly magnetic headspace single-drop microextraction (Mag-HS-SDME) based on a magnetic ionic liquid (MIL) as an extractant solvent is presented. A small drop of the MIL 1-ethyl-3 methylimidazolium tetraisothiocyanatocobaltate(II) ([Emim]2[Co(NCS)4]) is located on one end of a small neodymium magnet to extract nine chlorobenzenes (1,2 dichlorobenzene, 1,3-dichlorobenzene, 1,4-dichlorobenzene, 1,2,3 trichlorobenzene, 1,2,4-trichlorobenzene, 1,3,5-trichlorobenzene, 1,2,3,4 tetrachlorobenzene, 1,2,4,5-tetrachlorobenzene, and pentachlorobenzene) as model analytes from water samples prior to thermal desorption-gas chromatography-mass spectrometry determination. A multivariate optimization strategy was employed to optimize experimental parameters affecting Mag-HS-SDME. The method was evaluated under optimized extraction conditions (i.e., sample volume, 20 mL; MIL volume, 1 MUL; extraction time, 10 min; stirring speed, 1500 rpm; and ionic strength, 15% NaCl (w/v)), obtaining a linear response from 0.05 to 5 MUg L-1 for all analytes. The repeatability of the proposed method was evaluated at 0.7 and 3 MUg L-1 spiking levels and coefficients of variation ranged between 3 and 18% (n = 3). Limits of detection were in the order of nanograms per liter ranging from 4 ng L 1 for 1,4-dichlorobenzene and 1,2,3,4-tetrachlorobenzene to 8 ng L-1 for 1,2,4,5 tetrachlorobenzene. Finally, tap water, pond water, and wastewater were selected as real water samples to assess the applicability of the method. Relative recoveries varied between 82 and 114% showing negligible matrix effects.

AB - OBJECTIVES: To evaluate the feasibility and time saving of fusing CT and MR enterography with ultrasound for ultrasound molecular imaging (USMI) of inflammation in an acute small bowel inflammation of swine. METHODS: Nine swine with ileitis were scanned with either CT (n = 3) or MR (n = 6) enterography. Imaging times to load CT/MR images onto a clinical ultrasound machine, fuse them to ultrasound with an anatomical landmark-based approach, and identify ileitis were compared to the imaging times without anatomical road mapping. Inflammation was then assessed by USMI using dual selectin-targeted (MBSelectin) and control (MBControl) contrast agents in diseased and healthy control bowel segments, followed by ex vivo histology. RESULTS: Cross-sectional image fusion with ultrasound was feasible with an alignment error of 13.9 +/- 9.7 mm. Anatomical road mapping significantly reduced (P < 0.001) scanning times by 40%. Localising ileitis was achieved within 1.0 min. Subsequently performed USMI demonstrated significantly (P < 0.001) higher imaging signal using MBSelectin compared to MBControl and histology confirmed a significantly higher inflammation score (P = 0.006) and P- and E-selectin expression (P <= 0.02) in inflamed vs. healthy bowel. CONCLUSIONS: Fusion of CT and MR enterography data sets with ultrasound in real time is feasible and allows rapid anatomical localisation of ileitis for subsequent quantification of inflammation using USMI. KEY POINTS: * Real-time fusion of CT/MRI with ultrasound to localise ileitis is feasible. * Anatomical road mapping using CT/MRI significantly decreases the scanning time for USMI. * USMI allows quantification of inflammation in swine, verified with ex vivo histology. PMID- 29170799 TI - MHC haplotype diversity in Persian Arabian horses determined using polymorphic microsatellites. AB - Previous research on the equine major histocompatibility complex (MHC) demonstrated strong correlations between haplotypes defined by polymorphic intra MHC microsatellites and haplotypes defined using classical serology. Here, we estimated MHC diversity in a sample of 124 Arabian horses from an endangered strain native to Iran (Persian Asil Arabians), using a validated 10-marker microsatellite panel. In a group of 66 horses related as parent-offspring pairs or half-sibling groups, we defined 51 MHC haplotypes, 49 of which were new. In 47 of the remaining 58 unrelated horses, we could assign one previously identified MHC haplotype, and by default, we gave provisional haplotype status to the remaining constellation of microsatellite alleles. In these horses, we found 21 haplotypes that we had previously defined and 31 provisional haplotypes, two of which had been identified in an earlier study. This gave a total of 78 new MHC haplotypes. The final 11 horses were MHC heterozygotes that we could not phase using information from any of the previously validated or provisional haplotypes. However, we could determine that these horses carried a total of 22 different undefined haplotypes. In the overall population sample, we detected three homozygous horses and one maternally inherited recombinant from 21 informative segregations. Virtually all of the horses tested were MHC heterozygotes, and most unrelated horses (98%) were heterozygous for rare microsatellite-defined haplotypes found less than three times in the sampled horses. This is evidence for a very high level of MHC haplotype variation in the Persian Asil Arabian horse. PMID- 29170801 TI - Immunity and immunopathology in early human life.

AB - PURPOSE: Data on panitumumab dosing in cancer patients with renal insufficiency are lacking. Here, we report a 63-year-old metastatic colorectal cancer patient with chronic kidney injury with a glomerular filtration rate of approximately 11 mL/min. METHODS: Pharmacokinetic parameters, including dose-normalized area under the curve, clearance and elimination half-life (T 1/2) after the 11th and 12th infusions were estimated using trapezoidal non-compartmental methods. Data were compared to previous reported pharmacokinetic data from studies in patients with normal renal function. RESULTS: The results show that the pharmacokinetic data in this patient with kidney failure are comparable to those in patients with adequate renal function. Moreover the treatment was well tolerated in this patient. CONCLUSION: This study suggests that panitumumab can be safely used in cancer patients with renal impairment without dose adjustment.

AB - A novel bacterial strain MAH-8T was isolated from a soil sample of a Korean pine garden and was characterized using a polyphasic approach. Cells were Gram staining negative, pinkish yellow colored, motile and vibrio-shaped. The strain was aerobic and catalase, oxidase positive, optimum growth temperature and pH were 28-30 degrees C and 7.0, respectively. On the basis of 16S rRNA gene sequence analysis, strain MAH-8T belongs to the genus Caenispirillum and is most closely related to Caenispirillum bisanense KCTC 12839T (98.14%), Caenispirillum deserti KCTC 42064T (96.35%), and Caenispirillum salinarum JCM 17360T (95.76%). In DNA-DNA hybridization tests, the DNA relatedness between strain MAH-8T and its closest phylogenetic neighbor was below 45.0%. The DNA G + C content was 70.5 mol% and the predominant respiratory quinone was ubiquinone-10. Flexirubin-type pigments were present and the major cellular fatty acids were C18:1 omega7c/C18:1 omega6c, C16:1 omega7c/C16:1 omega6c and C16:0. The results of DNA-DNA hybridization and genotypic analysis in combination with chemotaxonomic and physiological data demonstrated that strain MAH-8T represented a novel species within the genus Caenispirillum, for which the name Caenispirillum humi, is proposed. The type strain is MAH-8T (= KACC 19294T = CGMCC 1.16224T). The NCBI GenBank Accession Number for the 16S rRNA gene sequence of strain MAH-8T is KY964275.

AB - Type 1 diabetes (T1D) is perceived as a chronic immune-mediated disease with a subclinical prodromal period characterized by selective loss of insulin-producing beta cells in the pancreatic islets in genetically susceptible subjects. The incidence of T1D has increased manifold in most developed countries after World War II in parallel with a series of other immune-mediated diseases. T1D results from gene-environmental interactions. The appearance of disease-associated autoantibodies into the peripheral circulation is the first detectable sign of the initiation of the disease process leading to clinical T1D. The first autoantibodies may appear already before the age of 6 months and the seroconversion rate peaks during the second year of life. This implies that exogenous factors involved in the pathogenesis of T1D must be operative in early life, some of them most likely already during pregnancy. Here, we discuss putative endogenous factors that may contribute to the development of T1D during fetal and early postnatal life. Many environmental factors operative in early life have been implicated in the pathogenesis of T1D, but relatively few have been firmly confirmed.

PMID- 29170805 TI - Role of actin depolymerizing factor cofilin in Aspergillus fumigatus oxidative stress response and pathogenesis. AB - Aspergillus fumigatus is a major fungal pathogen that is responsible for approximately 90% of human aspergillosis. Cofilin is an actin depolymerizing factor that plays crucial roles in multiple cellular functions in many organisms. However, the functions of cofilin in A. fumigatus are still unknown. In this study, we constructed an A. fumigatus strain overexpressing cofilin (cofilin OE). The cofilin OE strain displayed a slightly different growth phenotype, significantly increased resistance against H2O2 and diamide, and increased activation of the high osmolarity glycerol pathway compared to the wild-type strain (WT). The cofilin OE strain internalized more efficiently into lung epithelial A549 cells, and induced increased transcription of inflammatory factors (MCP-1, TNF-alpha and IL-8) compared to WT. Cofilin overexpression also resulted in increased polysaccharides including beta-1, 3-glucan and chitin, and increased transcription of genes related to oxidative stress responses and polysaccharide synthesis in A. fumigatus. However, the cofilin OE strain exhibited similar virulence to the wild-type strain in murine and Galleria mellonella infection models. These results demonstrated for the first time that cofilin, a regulator of actin cytoskeleton dynamics, might play a critical role in the regulation of oxidative stress responses and cell wall polysaccharide synthesis in A. fumigatus. PMID- 29170806 TI - Environmentally prevalent polycyclic aromatic hydrocarbons can elicit co carcinogenic properties in an in vitro murine lung epithelial cell model. AB - Low molecular weight (LMW) polycyclic aromatic hydrocarbons (PAH) are the most abundant PAHs environmentally, occupationally, and are in cigarette smoke; however, little is known about their carcinogenic potential. We hypothesized that LMW PAHs act as co-carcinogens in the presence of a known carcinogen (benzo[a]pyrene (B[a]P)) in a mouse non-tumorigenic type II cell line (C10 cells). Gap junctions are commonly suppressed and inflammation induced during tumor promotion, while DNA-adduct formation is observed during the initiation stage of cancer. We used these endpoints together as markers of carcinogenicity in these lung adenocarcinoma progenitor cells. LMW PAHs (1-methylanthracene and fluoranthene, 1-10 uM total in a 1:1 ratio) were used based on previous studies as well as B[a]P (0-3 uM) as the classic carcinogen; non-cytotoxic doses were used. B[a]P-induced inhibition of gap junctional intercellular communication (GJIC) was observed at low doses and further reduced in the presence of the LMW PAH mixture (P < 0.05), supporting a role for GJIC suppression in cancer development. Benzo[a]pyrene diol-epoxide (BPDE)-DNA adduct levels were significantly induced in B[a]P-treated C10 cells and additionally increased with the LMW PAH mixture (P < 0.05). Significant increases in cyclooxygenase (Cox-2) were observed in response to the B[a]P/LMW PAH mixture combinations. DNA adduct formation coincided with the inhibition of GJIC and increase in Cox-2 mRNA expression. Significant cytochrome p4501b1 increases and connexin 43 decreases in gene expression were also observed. These studies suggest that LMW PAHs in combination with B[a]P can elicit increased carcinogenic potential. Future studies will further address the mechanisms of co-carcinogenesis driving these responses.

AB - The current study reports the modification of prokaryotic microorganism through a single-layer technique by using different polyanions/cations and doping with magnetic (Fe3O4) nanoparticles. Briefly, individual Escherichia coli cells were encapsulated through deposition of 1% sodium alginate as first layer followed by depositing precipitate layers of calcium chloride, disodium hydrogen phosphate, and Fe3O4 nanoparticles. Surface and cross sectional analysis of modified E. coli cells by field emission scanning electron microscope (FE-SEM) confirmed the synthesis of varying sizes of artificial shells around the microbial cells while the deposition of Fe3O4 nanoparticles was confirmed by transmission electron microscope (TEM). Thermogravimetric analysis (TGA) showed the deposition of 58 wt% of Fe3O4 nanoparticles on E. coli cell surface. Chemical structure analysis by Fourier transform infrared (FTIR) spectroscopy confirmed the presence of characteristic functional groups of deposited reagents in the hydrogel capsule. Zeta potential analysis of hydrogel capsule showed moderate stability with a surface charge of - 21 mV. Growth and viability analysis by Alamar Blue assay indicated marked increase in the reduction of resazurin blue (> 100%) by the modified E. coli indicating their viability. The movement and control of magnetized E. coli cells were manipulated using external permanent magnetic field as observed with optical microscope images. The surface-modified cells can find potential applications in bioremediation, biodegradation, and catalysis and can be used as biosorbents.

PMID- 29170811 TI - Triple elastofibromas located in the supra- and infrascapular regions-a case report. AB - We report a case of triple elastofibromas located in the supra- and infrascapular regions. A 61-year-old female with a history of bilateral elastofibroma in the typical subscapular region (6 years before) was admitted for the evaluation of a left-sided suprascapular mass that she had first noted 3 months before. On physical examination, a firm, painless, mobile mass was palpated in the subcutaneous tissue. The patient had not observed any changes of the two known lesions over the past 6 years. The patient denied a family history of elastofibroma. The signal characteristic on T1- and T2-weighted images as well as contrast enhancement curves on dynamic study was identical in all three masses. Ultrasound-guided biopsy performed before surgical intervention confirmed the diagnosis of elastofibroma. This case report has a teaching value as, to our knowledge, it is the only one in the literature with images of synchronous elastofibromas documented by dynamic contrast-enhanced MRI. In cases of elastofibroma with diagnostic difficulties, particularly in uncommon sites, a dynamic contrast-enhanced MRI may help to establish the proper diagnosis. This case report gives an example of rare multiple elastofibromas, presents current diagnostic imaging methods, and reminds us that elastofibroma is not exclusive to the posterior thoracic region.

AB - This retrospective study attempts to establish if a correlation exists between osteoporosis and hematopoiesis before and after adjuvant chemotherapy in the context of non-metastatic breast cancer. Osteoporosis is interpreted both as a direct marker of osteoblastic decline and as an indirect marker of increased bone marrow adiposity within the hematopoietic microenvironment. Patients from the "Centre du Sein" at CHUV (Centre Hospitalier Universitaire Vaudois) undergoing adjuvant chemotherapy were included in this study. Evolution of blood counts was studied in correlation with the osteoporosis status. Toxicity of chemotherapy was coded according to published probability of febrile neutropenia. One hundred forty-three women were included: mean age 52.1 +/- 12.5 years, mean BMI (body mass index) 24.4 +/- 4.1. BMD (bone mineral density) scored osteoporotic in 32% and osteopenic in 45%. Prior to chemotherapy, BMD was positively correlated with neutrophil (p < 0.001) and thrombocyte (p = 0.01) count; TBS (trabecular bone score) was not correlated with blood count. After the first cycle of chemotherapy, an increase of one point in TBS correlated with a decrease of 57% on the time to reach leucocyte nadir (p = 0.004). There was a positive correlation between BMD and risk of infection (p < 0.001). Our data demonstrates an association between osteoporosis and lower blood counts in a younger cohort than previously published, extending it for the first time to neutrophil counts in females. Our results suggest that the healthier the bone, the earlier the lowest leucocyte count value, prompting further research on this area. PMID- 29170812 TI - Avulsion fracture of an ossified pes anserinus tendon post-lateral patellar dislocation. AB - The pes anserinus is a common tendon comprising the tendinous insertions of the sartorius, gracilis, and semitendinosus muscles. It inserts at the anteromedial aspect of the tibia and plays a significant role in stabilization of the medial side of the knee joint. The current article presents a case with recurrent lateral patellar dislocations causing chronic stress along the medial knee stabilizers and consecutive enthesophyte formation at the insertion of the pes anserinus tendon that showed a transverse fracture upon a subsequent incident of traumatic lateral patellar dislocation. Avulsion injuries of the pes anserinus tendon are rarely encountered, and to our knowledge, association with recurrent lateral patellar dislocations has not been described before. PMID- 29170813 TI - MRI in chronic groin pain: sequence diagnostic reliability compared to systematic surgical assessment. AB - OBJECTIVE: To determine the diagnostic reliability of magnetic resonance imaging (MRI) sequences in chronic groin pain (CGP) compared to surgery and try to propose a suitable MRI protocol. MATERIALS AND METHODS: Forty-three consecutive patients with resistant clinical CGP underwent a pre-surgical pelvis MRI. Eight MRI sequences were acquired: axial fast spin-echo T1-weighted (FSE T1), coronal FSE T1, axial-oblique (in symphysis plane) proton density weighted with fat saturation (PDFS), coronal PDFS, sagittal PDFS, axial FSE T1 with fat saturation and gadolinium enhancement (FSGE), coronal FSE T1 FSGE and axial FSE T1 with Valsalva maneuver (VM). These sequences were reviewed for pubic symphysis assessment, adductor longus (AL) tendon and abdominal wall (AW) injuries. The same surgeon operated on all of these patients (26 AL and 49 AW). Sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative prospective value (NPV) and accuracy of each sequence and combinations for AL or AW injuries were calculated in comparison to surgical findings. RESULTS: One hundred ninety two sequences were obtained. Coronal T1 FSGE and axial T1 VM proved to be the most reliable sequences (accuracy: 91.67% in AL and 83.33% in AW). The best sequence combination was coronal T1, axial PDFS, sagittal PDFS and axial T1 VM (accuracy: 77.78%; Se: 100.00%, Sp: 69.23%, PPV: 55.56%, NPV: 100.00%). CONCLUSION: MRI has 77.78% accuracy, 100.00% sensitivity, 69.23% specificity, 55.56% PPV and 100.00% NPV in evaluating CGP, with coronal T1-axial PDFS-sagittal PDFS-axial T1 VM as the optimal protocol in terms of diagnostic performance within a reasonable scan time. Diagnostic performance of MRI was examined in the evaluation of CGP using surgery as reference standard. PMID- 29170815 TI - Management of post-midurethral sling voiding dysfunction. International Urogynecological Association research and development committee opinion. AB - Voiding dysfunction following midurethral sling procedures is not a rare event. There is no current consensus regarding management of this complication. Although it is often transient and self-limiting, chronic post-midurethral sling voiding dysfunction may lead to irreversible changes affecting detrusor function. Initial management includes intermittent catheterization, and addressing circumstantial factors interfering with normal voiding, such as pain. Early sling mobilization often resolves the dysfunction, and is associated with minimal morbidity. Sling incision or excision at a later stage, although fairly effective, could be associated with recurrence of stress urinary incontinence. There is insufficient evidence to justify urethral dilatation in this context. PMID- 29170816 TI - Umbilical cord entanglement's frequency and its impact on the newborn. AB - Neonaticide is a serious allegation that needs a complete chain of criminal investigations. In this context, a nuchal cord is considered to be responsible for an infant's death, but there is a clear lack of evidence. The purpose of our study is to reveal if a nuchal cord can be responsible for stillbirth, poor perinatal outcome, or neonatal death in the forensic aspect. We conducted a prospective study in collaboration with the Augustinian Sisters' Hospital in Cologne, Germany in the period from February 2014 to May 2016. Four-hundred eighty-six children were enrolled. All births were assessed regarding the occurrence of an umbilical cord entanglement, and perinatal outcome was measured by arterial blood gas analysis, Apgar after 1, 5, and 10 min after birth as well as the general vitality. The prevalence of a nuchal cord was 16.87%. Apgar decrease and acidosis were significantly associated with a nuchal cord. No adverse perinatal outcome was recorded in this constellation. There was no child death regarding the first 24 h, and no mother experienced a syncope while giving birth. We can conclude that a nuchal cord is not associated with adverse perinatal outcome.

PMID- 29170817 TI - Postmortem 1H-MRS-Detection of Ketone Bodies and Glucose in Diabetic Ketoacidosis. AB - Diabetic ketoacidosis (DKA) is a metabolic complication of diabetes mellitus that takes a lethal course if untreated. In this way relevant to forensic medicine, secure diagnosis of DKA usually involves the evidence of elevated levels of glucose and the ketone bodies acetone, acetoacetate, and beta-hydroxybutyrate in corpse fluids. We conducted a postmortem hydrogen proton magnetic resonance spectroscopy (1H-MRS) in a case of lethal DKA. Distinctive resonances of all three ketone bodies as well as glucose were visible in spectra of cerebrospinal fluid, vitreous humor, and white matter. Estimated concentrations of ketone bodies and glucose supported the findings both of autopsy and biochemical analysis. Advantages of human postmortem 1H-MRS are the lack of movement and flow artifacts as well as lesser limitations of scan duration. Postmortem 1H-MRS is able to non-invasively measure concentrations of glucose and ketone bodies in small volumes of various regions of the brain. It may thus become a diagnostic tool for forensic investigations by quick determination of pathological metabolite concentrations in addition to conventional autopsy. PMID- 29170819 TI - Tongue Pressure Production and Submental Surface Electromyogram Activities During Tongue-Hold Swallow with Different Holding Positions and Tongue Length. AB - Our previous study regarding the tongue-hold swallow (THS) demonstrated that the tongue-to-palate contact during THS could be influenced by the maximum tongue protrusion length (MTPL) of individual subjects, resulting in two different patterns of pressure generation. The present study further analyzed the influence of MTPL on the tongue pressure production along with submental surface electromyography (sEMG) during THS, in order to establish an index to better control THS effects. Tongue pressure using a sensor sheet system and concurrent submental sEMG activities were measured during swallowing tasks in 18 healthy young adults. Task conditions comprised THS at two different degrees of tongue protrusion and dry swallow. Tongue pressures and sEMG activities were compared among three task conditions, and correlations of MTPL with tongue pressure were also investigated. Additionally, a ROC curve was used to find a cut-off value for MTPL to predict changes (increases and decreases) in tongue pressure during THS. The duration and the amount of submental muscle activity increased concurrently during THS. Two trends were shown on the change in tongue pressure at the posterior-circumferential part of the hard palate during THS compared to dry swallow; the maximal magnitude and the integrated value of tongue pressure increased in some subjects, while these values decreased in others. Thirty-two millimeters was found to be the cut-off value of MTPL, which distinguishes increase/decrease pattern of tongue pressure with sensitivities of 60.0-85.7%. The present finding suggests that more reliable THS effects should be attainable using MTPL to set the tongue-hold position. PMID- 29170820 TI - Decoupling habitat fragmentation from habitat loss: butterfly species mobility obscures fragmentation effects in a naturally fragmented landscape of lake islands. AB - Since the publication of the theory of island biogeography, ecologists have postulated that fragmentation of continuous habitat presents a prominent threat to species diversity. However, negative fragmentation effects may be artifacts; the result of species diversity declining with habitat loss, and habitat loss correlating positively with degree of fragmentation. In this study, we used butterfly assemblages on islands of Lake of the Woods, Ontario, Canada to decouple habitat fragmentation from habitat loss and test two competing hypotheses: (1) the island effect hypothesis, which predicts that decreasing fragment size and increasing fragment isolation reduces species diversity beyond the effects of habitat loss, and (2) the habitat amount hypothesis, which negates fragmentation effects and predicts that only total habitat area determines the diversity of species persisting on fragmented landscapes. Using eight independent size classes of islands (ranging from 0.1 to 8.0 ha) that varied in number of islands while holding total area constant, species diversity comparisons, species accumulation curves, and species-area relationship extrapolations demonstrated that smaller insular habitats contained at least as many butterfly species as continuous habitat. However, when highly mobile species occurring on islands without their larval food plants were excluded from analyses, island effects on potentially reproducing species became apparent. Similarily, generalized linear models suggested that effects of island isolation and vascular plant richness on insular butterfly richness were confounded by species of high mobility. We conclude that inter-fragment movements of highly mobile species may obscure important fragmentation effects on potentially reproducing populations, questioning support for the habitat amount hypothesis. PMID- 29170821 TI - Weather-driven change in primary productivity explains variation in the amplitude of two herbivore population cycles in a boreal system. AB - Vertebrate populations throughout the circumpolar north often exhibit cyclic dynamics, and predation is generally considered to be a primary driver of these cycles in a variety of herbivore species. However, weather and climate play a role in entraining cycles over broad landscapes and may alter cyclic dynamics, although the mechanism by which these processes operate is uncertain. Experimental and observational work has suggested that weather influences primary productivity over multi-year time periods, suggesting a pathway through which weather and climate may influence cyclic herbivore dynamics. Using long-term monitoring data, we investigated the relationships among multi-year weather conditions, measures of primary productivity, and the abundance of two cyclic herbivore species: snowshoe hare and northern red-backed vole. We found that precipitation (rain and snow) and growing season temperatures were strongly associated with variation in primary productivity over multi-year time horizons. In turn, fourfold variation in the amplitude of both the hare and vole cycles observed in our study area corresponded to long-term changes in primary productivity. The congruence of our results for these two species suggests a general mechanism by which weather and climate might influence cyclic herbivore population dynamics. Our findings also suggested that the association between climate warming and the disappearance of cycles might be initiated by changes in primary productivity. This work provides an explanation for observed influences of weather and climate on primary productivity and population cycles and will help our collective understanding of how future climate warming may influence these ecological phenomena in the future.

AB - PURPOSE: Anastomotic stricture after esophagectomy is a major cause of long-term morbidity and a poor quality of life. The aim of this study was to identify the risk factors for the development of anastomotic stricture after esophagectomy. METHODS: The study subjects were 213 patients who underwent esophagectomy for squamous cell carcinoma of the esophagus between 2012 and 2014. Anastomotic stricture was defined as stenosis at the site of anastomosis that required endoscopic dilation. Refractory stricture was defined as that requiring more than four sessions of dilations. Univariate and multivariate logistic regression analyses were used to identify the potential risk factors for the development of anastomotic stricture. RESULTS: In this retrospective study, 29 patients (13.6%) developed anastomotic stricture within a median period of 108 postoperative days and required a median of 2 dilations. Tumors located in the upper part of the esophagus (p = 0.004), the presence of cardiovascular disease (p = 0.024) and anastomotic leakage (p = 0.002) were identified as independent risk factors for the development of anastomotic stricture. The time to the diagnosis of refractory stricture (85 +/- 33 days) was significantly shorter than that of non-refractory stricture (171 +/- 22 days, p = 0.038). CONCLUSIONS: Patients with squamous cell carcinoma in the upper esophagus with cardiovascular disease who develop postoperative anastomotic leakage should be carefully monitored to prevent the development of benign anastomotic stricture. PMID- 29170825 TI - [Psychosomatic medicine in old age]. AB - Approximately 25% of people over 65 years old suffer from psychiatric disorders but in cases of simultaneously occurring somatic diseases the prevalence is increased. Sickness, loss of important reference persons and life crises in older age often reactivate traumatic experiences from earlier life stages. It can be difficult to differentiate between psychological disorders and the psychological symptoms accompanying somatic illness. The biographic medical history and estimation of cognitive skills within a geriatric basis assessment should be standard in geriatric diagnostics. Psychological disorders are often overlooked or inadequately treated in older people. In the case of psychopharmacological treatment, effects on somatic sickness as well as drug-drug interactions have to be kept in mind. Psychotherapeutic approaches focusing on resources and social support particularly in group therapy seem to be very helpful. PMID- 29170823 TI - Engineering new neurons: in vivo reprogramming in mammalian brain and spinal cord. AB - Neurons are postmitotic. Once lost because of injury or degeneration, they do not regenerate in most regions of the mammalian central nervous system. Recent advancements nevertheless clearly reveal that new neurons can be reprogrammed from non-neuronal cells, especially glial cells, in the adult mammalian brain and spinal cord. Here, we give a brief overview concerning cell fate reprogramming in vivo and then focus on the underlying molecular and cellular mechanisms. Specifically, we critically review the cellular sources and the reprogramming factors for in vivo neuronal conversion. Influences of environmental cues and the challenges ahead are also discussed. The ability of inducing new neurons from an abundant and broadly distributed non-neuronal cell source brings new perspectives regarding regeneration-based therapies for traumatic brain and spinal cord injuries and degenerative diseases. PMID- 29170826 TI - Increased pericardial adipose tissue and cardiometabolic risk in patients with schizophrenia versus healthy controls. AB - Patients with schizophrenia are at increased risk of diabetes, cardiovascular disease (CVD) and associated mortality versus the general population. Increased intra-abdominal and pericardial adipose tissue are associated with elevated CVD and mortality in the general population, but little is known about these in patients with schizophrenia. This study examined pericardial and intra-abdominal adipose tissue in schizophrenia and compared this to healthy controls. Thirty-one patients with schizophrenia (mean age 41.2 years, 76% males) and 30 healthy volunteers (CTRL) were examined in this study. The primary outcomes were the volumes of pericardial adipose tissue and intra-abdominal adipose tissue, measured using magnetic resonance imaging. Secondary outcomes included diabetes and cardiac event risk assessed by established instruments. Volumes of pericardial adipose tissue were increased in male and female patients with schizophrenia compared to healthy controls after the adjustment of age, sex and body mass index (P < 0.005). The 10-year risk of a cardiac event was significantly higher in patients with schizophrenia. Furthermore, the risk for developing type-2 diabetes mellitus was slightly increased in schizophrenia. Volumes of intra-abdominal adipose tissue were slightly increased in male and female patients with schizophrenia, albeit not statistically significant. This study demonstrates that patients with schizophrenia have increased pericardial adipose tissue versus controls. This increased fat deposit around the heart is highly relevant for understanding the comorbidity between heart disease and schizophrenia. Interventions aiming to reduce pericardial and intra-abdominal adipose tissue, such as exercise, may be essential to reduce the burden of heart disease in schizophrenia. PMID- 29170828 TI - A novel trifunctional, family GH10 enzyme from Acidothermus cellulolyticus 11B, exhibiting endo-xylanase, arabinofuranosidase and acetyl xylan esterase activities. AB - A novel, family GH10 enzyme, Xyn10B from Acidothermus cellulolyticus 11B was cloned and expressed in Escherichia coli. This enzyme was purified to homogeneity by binding to regenerated amorphous cellulose. It had higher binding on Avicel as compared to insoluble xylan due to the presence of cellulose-binding domains, CBM3 and CBM2. This enzyme was optimally active at 70 degrees C and pH 6.0. It was stable up to 70 degrees C while the CD spectroscopy analysis showed thermal unfolding at 80 degrees C. Xyn10B was found to be a trifunctional enzyme having endo-xylanase, arabinofuranosidase and acetyl xylan esterase activities. Its activities against beechwood xylan, p-Nitrophenyl arabinofuranoside and p Nitrophenyl acetate were found to be 126,480, 10,350 and 17,250 U MUmol-1, respectively. Xyn10B was highly active producing xylobiose and xylose as the major end products, as well as debranching the substrates by removing arabinose and acetyl side chains. Due to its specific characteristics, this enzyme seems to be of importance for industrial applications such as pretreatment of poultry cereals, bio-bleaching of wood pulp and degradation of plant biomass. PMID- 29170827 TI - The role of nanomaterials in cell delivery systems. AB - In more than one decade, cell transplantation has created an important strategy to treat a wide variety of diseases characterized by tissue and cell dysfunctions. In this course of action, cell delivery to target site has been always one of the most important constraints and complications, as only a small proportion of the cells are housed in the target sites. Nanotechnology and nanoscale biomaterials have been helpful for cell transplantation in various fields of regenerative medicine including diagnosis, delivery systems for the cell, drug or gene, and cells protection system. In this study, the basic concepts and recently studied aspects of cell delivery systems based on nanoscale biomaterials for transplantation and clinical applications are highlighted. Nanomaterials may be used in combination with cell therapy to control the release of drugs or special factors of engineered cells after transplantation.

PMID- 29170830 TI - Genetic analysis of three porcine bocaparvoviruses and identification of a natural recombinant breakpoint in NS1. AB - In this study, we obtained the whole genomes of three porcine bocaparvovirus (PBoV) strains (GD6, GD10, and GD23) by polymerase chain reaction. Sequence analysis showed that all three field strains belonged to PBoV group 3 (G3). The phylogenetic trees based on NS1, NP1, and VP1 differed to the extent that these PBoVs were potentially more closely related to bocaparvoviruses known to infect other animals than to other PBoVs. GD6, GD10, and GD23 all included the conserved sequences YLGPF and HDXXY, with known phospholipase A2 activity. Using recombination-detection software we identified a natural recombinant breakpoint in the NS1 region of PBoV G3. The results of this study will further the epidemiological characterization of PBoVs. PMID- 29170831 TI - Mutation independently affects reproductive traits and dauer larvae development in mutation accumulation lines of Caenorhabditis elegans. AB - Developmental decisions are important in organismal fitness. For the nematode Caenorhabditis elegans, which is naturally found in the ephemeral food patches formed by rotting plant material, correctly committing to dauer or non-dauer larval development is key to genotype survival. To investigate the link between reproductive traits, which will determine how populations grow, and dauer larvae formation, we have analysed these traits in mutation accumulation lines of C. elegans. We find that reproductive traits of individual worms-the total number of progeny and the timing of progeny production-are highly correlated with the population size observed in growing populations. In contrast, we find no relationship between reproduction traits and the number of dauer larvae observed in growing populations. We also do not observe a mutational bias in dauer larvae formation. These results indicate that the control of dauer larvae formation is distinct from the control of reproduction and that differences in dauer larvae formation can evolve rapidly. PMID- 29170832 TI - Spectrophotometric determination of anionic surfactants: optimization by response surface methodology and application to Algiers bay wastewater. AB - A simple analytical method for quantitative determination of an anionic surfactant in aqueous solutions without liquid-liquid extraction is described. The method is based on the formation of a green-colored ion associate between sodium dodecylbenzenesulfonate (SDBS) and cationic dye, Brilliant Green (BG) in acidic medium. Spectral changes of the dye by addition of SDBS are studied by visible spectrophotometry at maximum wave length of 627 nm. The interactions and micellar properties of SDBS and cationic dye are also investigated using surface tension method. The pH, the molar ratio ([BG]/[SDBS]), and the shaking time of the solutions are considered as the main parameters which affect the formation of the ion pair. Determination of AS in distilled water gives a significant detection limit up to 3 * 10-6 M. The response surface methodology (RSM) is applied to study the absorbance. A Box-Behnken is a model designed to the establishment of responses given by parameters with great probability. This model is set up by using the three main parameters at three levels. Analysis of variance shows that only two parameters affect the absorbance of the ion pair. The statistical results obtained are interesting and give us real possibility to reach optimum conditions for the formation of the ion pair. As the proposed method is free from interferences from major constituents of water, it has been successfully applied to the determination of anionic surfactant contents in wastewaters samples collected from Algiers bay. PMID- 29170833 TI - Inclusion of Assistive Technologies in a Basic Package of Essential Healthcare Service. AB - This paper outlines the potential and necessity of the development of assistive technologies (AT) for people with intellectual disabilities (IDs). We analyse a policy recommendation designed to determine the contents of a basic health package supplied by the state, known as the Dunning Funnel. We contend that the Dunning Funnel is a useful methodology, but is weakened by a potentially relativistic understanding of "necessity" in relation to the requirements of people with IDs (i.e., community standards will determine whether AT are necessary). We remedy this defect by using the capabilities approach as outlined by Martha Nussbaum. We argue that this approach provides a strong normative case for ensuring that communities provide help to people with IDs, if those communities are to achieve a minimal standard of justice. However, the capabilities approach does not offer much specific guidance on how AT ought to be distributed, nor does it offer guidance on risks, like the bottomless pit problem. We propose that the Dunning Funnel used in combination with the capabilities approach will provide a suitable heuristic for determining the distribution of AT in a basic health package. PMID- 29170835 TI - Entomopathogen ID: a curated sequence resource for entomopathogenic fungi. AB - We report the development of a publicly accessible, curated nucleotide sequence database of hypocrealean entomopathogenic fungi. The goal is to provide a platform for users to easily access sequence data from taxonomic reference strains. The database can be used to accurately identify unknown entomopathogenic fungi based on sequence data for a variety of phylogenetically informative loci. The database provides full multi-locus sequence alignment capabilities. The initial release contains data compiled for 525 strains covering the phylogenetic diversity of three important entomopathogenic families: Clavicipitaceae, Cordycipitaceae, and Ophiocordycipitaceae. Furthermore, Entomopathogen ID can be expanded to other fungal clades of insect pathogens, as sequence data becomes available. The database will allow isolate characterisation and evolutionary analyses. We contend that this freely available, web-accessible database will facilitate the broader community to accurately identify fungal entomopathogens, which will allow users to communicate research results more effectively. PMID- 29170834 TI - Emerging roles of cortical microtubule-membrane interactions. AB - Plant cortical microtubules have crucial roles in cell wall development. Cortical microtubules are tightly anchored to the plasma membrane in a highly ordered array, which directs the deposition of cellulose microfibrils by guiding the movement of the cellulose synthase complex. Cortical microtubules also interact with several endomembrane systems to regulate cell wall development and other cellular events. Recent studies have identified new factors that mediate interactions between cortical microtubules and endomembrane systems including the plasma membrane, endosome, exocytic vesicles, and endoplasmic reticulum. These studies revealed that cortical microtubule-membrane interactions are highly dynamic, with specialized roles in developmental and environmental signaling pathways. A recent reconstructive study identified a novel function of the cortical microtubule-plasma membrane interaction, which acts as a lateral fence that defines plasma membrane domains. This review summarizes recent advances in our understanding of the mechanisms and functions of cortical microtubule membrane interactions. PMID- 29170836 TI - Phase-contrast cerebrospinal fluid flow magnetic resonance imaging in qualitative evaluation of patency of CSF flow pathways prior to infusion of chemotherapeutic and other agents into the fourth ventricle. AB - PURPOSE: Nuclear medicine studies have previously been utilized to assess for blockage of cerebrospinal fluid (CSF) flow prior to intraventricular chemotherapy infusions. To assess CSF flow without nuclear medicine studies, we obtained cine phase-contrast MRI sequences that assess CSF flow from the fourth ventricle down to the sacrum. METHODS: In three clinical trials, 18 patients with recurrent malignant posterior fossa tumors underwent implantation of a ventricular access device (VAD) into the fourth ventricle, either with or without simultaneous tumor resection. Prior to infusing therapeutic agents into the VAD, cine MRI phase contrast CSF flow sequences of the brain and total spine were performed. Velocity encoding (VENC) of 5 and 10 cm/s was used to confirm CSF flow from the fourth ventricular outlets to the cervical, thoracic, and lumbar spine. Qualitative CSF flow was characterized by neuroradiologists as present or absent. RESULTS: All 18 patients demonstrated CSF flow from the outlets of the fourth ventricle down to the sacrum with no evidence of obstruction. One of these patients, after disease progression, subsequently showed obstruction of CSF flow. No patient required a nuclear medicine study to assess CSF flow prior to initiation of infusions. Fourteen patients have received infusions to date, and none has had neurological toxicity. CONCLUSIONS: CSF flow including the fourth ventricle and the total spine can be assessed noninvasively with phase-contrast MRI sequences. Advantages over nuclear medicine studies include avoiding both an invasive procedure and radiation exposure. PMID- 29170837 TI - Post-traumatic carotid-cavernous fistula in a pediatric patient: a case-based literature review. AB - BACKGROUND: Carotid-cavernous fistula (CCF) is a shunt between the carotid artery and the cavernous sinus. Traumatic CCFs are diagnosed in 0.2% of head traumas being only 4.6% of the pediatric population. Classified by Barrow in 1985, type A CCF is the most frequent, occurring in 75% of cases. Type A is characterized by direct and high-flow CCF that generally can occur as a result of traumatic injury or rupture of an intracavernous aneurysm. CASE PRESENTATION: The subject was an 8 year-old boy with penetrating trauma to his left eye. During the initial evaluation, a computed tomography (CT) scan was unremarkable, and after relief of symptoms, the patient was discharged. Seven days later, he developed grade I proptosis, conjunctival chemosis, ophthalmoplegia (III, IV, and VI cranial nerve palsies), and left-sided ptosis and mydriasis. Arteriography confirmed a post traumatic CCF, and the patient was treated with an endovascular detachable balloon. CONCLUSION: CCF should be suspected in craniofacial traumas with ocular symptoms. The presence of a skull base fracture on CT is a poor predictor of CCF associated with head trauma. Early diagnosis and treatment can prevent permanent neurological deficits and unfavorable outcomes. PMID- 29170838 TI - Embolization of a traumatic arteriovenous fistula between the middle meningeal artery and middle meningeal vein in a child with pulsatile tinnitus. AB - Traumatic arteriovenous fistulas (AVFs) involving the middle meningeal artery (MMA) are uncommon lesions and rare in the pediatric population. An adolescent with headaches developed a bruit and a rhythmic "swooshing" noise in the left ear 9 weeks after a traumatic brain injury involving a left temporal bone fracture. An MRA of the brain demonstrated an enlarged left MMA and arterialized flow in the left middle meningeal vein (MMV), suggestive of an AVF. Cerebral angiography confirmed and characterized the left MMA-MMV fistula, which drained into the pterygoid plexus. The patient underwent transarterial coil embolization, with successful obliteration of the fistulous connection, and her tinnitus resolved. This case illustrates the importance of recognizing a post-traumatic AVF in a pediatric patient with pulsatile tinnitus, and that endovascular treatment by coil embolization is a safe and effective treatment option.

AB - BACKGROUND: The transanal hemorrhoidal dearterialization (THD) Doppler procedure is a minimally invasive technique to treat symptomatic hemorrhoids. The aim of the study was to assess the clinical efficacy and the satisfaction of patients in a large series treated with THD and to review the relevant literature. METHODS: In this retrospective, single-institution, study consecutive patients with grade 2, 3, or 4 hemorrhoidal disease were treated with the THD Doppler procedure. Dearterialization was performed in all cases and mucopexy in case of prolapse. The dearterialization procedure evolved from "proximal artery ligation" to "distal Doppler-guided dearterialization." Follow-up was scheduled at 15 days, 1, 3, 12 months, and once a year thereafter. Complications were recorded. Clinical efficacy was assessed comparing both frequency of symptoms and disease grading (Goligher's classification) at baseline versus last follow-up. Uni-/multivariate analysis evaluated factors affecting the outcome. RESULTS: There were 1000 patients (619 men; mean age: 48.6 years, range 19-88 years). Acute postoperative bleeding was observed in 14 patients (1.4%), pain/tenesmus in 31 patients (3.1%), and urinary retention in 23 patients (2.3%). At mean follow-up duration of 44 +/- 29 months, the symptomatic recurrence rate was 9.5% (95 patients; bleeding in 12 (1.2%), prolapse in 46 (4.6%), and bleeding and prolapse in 37 (3.7%) patients). The recurrence rate was 8.5, 8.7, and 18.1% in patients with grade 2, 3, and 4 hemorrhoids, respectively. Seventy out of 95 patients with recurrence needed surgery (reoperation rate: 7.0%). At final follow-up and taking into account the reoperations, 95.7% of patients had no hemorrhoidal disease on examination. Younger age, grade 4 disease, and high artery ligation affected the outcome negatively. CONCLUSIONS: Our results show that the THD Doppler procedure is safe and effective in patients with hemorrhoidal disease and associated with low morbidity and recurrence rates and a high rate percentage of treatment success. PMID- 29170840 TI - Early detection of cardiac alterations by left atrial strain in patients with risk for cardiac abnormalities with preserved left ventricular systolic and diastolic function. AB - This study sought to examine whether early cardiac alterations could be detected by left atrial (LA) strain in patients with risk for cardiac abnormalities. In this cross-sectional and retrospective study, we included patients with (n = 234) and without (n = 48) risk for cardiac abnormalities (i.e. those with arterial hypertension, diabetes mellitus and/or a history of coronary artery disease) of similar age and with preserved left ventricular (LV) systolic and diastolic function according to standard criteria. LA strain was significantly altered in patients with risk for cardiac abnormalities in comparison to those without risk (29.2 +/- 8.6 vs. 38.5 +/- 12.6%; rate of impaired LA strain: 18.8% vs. 0%; all p < 0.01) and was the most sensitive parameter to detect early LA alterations in comparison with other LA functional parameters (rate of impaired LA strain rate, LA total emptying fraction, and LA expansion index 3.8%, 7.3%, and 3.8%, respectively). Moreover, in patients with risk for cardiac abnormalities LA strain was altered even in the absence of subtle LV systolic and diastolic alterations (rates 13.9% and 6.8%), albeit to a lesser extent than in patients with an abnormal LV longitudinal systolic strain or abnormal mitral annular e' velocities (rates 48.5% and 24.4%). Regarding the clinical relevance of these findings, an impaired LA strain (i.e. < 23%) was significantly linked to exertional dyspnea (OR 3.5 [1.7-7.0]) even adjusting the analyses by age, gender and subtle LV abnormalities. In conclusion, the findings from this study suggest that LA strain measurements could be useful to detect early cardiac alterations in patients with risk for cardiac abnormalities with preserved LV systolic and diastolic function and that these early LA strain alterations could be linked to exertional dyspnea. PMID- 29170841 TI - Oxymatrine induces apoptosis and inhibits invasion in Gallbladder carcinoma via PTEN/PI3K/AKT pathway. AB - Oxymatrine extracted from Sophora flavescens Ait as a natural polyphenolic phytochemical has been demonstrated to exhibit anti-tumor effects on various cancers, including Gallbladder carcinoma (GBC). However, its underlying mechanisms of function are largely unknown in GBC cells. The present study is conducted to investigate the anti-tumor effects and the underlying mechanisms of oxymatrine on GBC cells in vitro and in vivo. The results showed that oxymatrine inhibited cell viability, metastatic ability and induced cell apoptosis in dose dependent manners. Furthermore, we found that the expression of p-AKT, MMP-2, MMP 9 and the ratio of Bcl-2/Bax were significantly down-regulated, while the expression of PTEN was up-regulated in GBC cells. In addition, pretreatment with a specific PI3K/AKT activator (IGF-1) significantly antagonized the oxymatrine mediated inhibition of GBC-SD cells. Subsequently, our in vivo studies showed that administration of oxymatrine induced a significant dose-dependent decrease in tumor growth. In conclusion, these findings indicated that the inhibition of cells proliferation, migration, invasion and the induction of apoptosis in response to oxymatrine in GBC cells, may function through the suppression of PTEN/PI3K/AKT pathway, which was considered as the vital signaling pathway in regulating tumorigenesis. These results suggested that oxymatrine might be a novel effective candidate as chemotherapeutic agent against GBC. PMID- 29170842 TI - Electropore Formation in Mechanically Constrained Phospholipid Bilayers. AB - Molecular dynamics simulations of lipid bilayers in aqueous systems reveal how an applied electric field stabilizes the reorganization of the water-membrane interface into water-filled, membrane-spanning, conductive pores with a symmetric, toroidal geometry. The pore formation process and the resulting symmetric structures are consistent with other mathematical approaches such as continuum models formulated to describe the electroporation process. Some experimental data suggest, however, that the shape of lipid electropores in living cell membranes may be asymmetric. We describe here the axially asymmetric pores that form when mechanical constraints are applied to selected phospholipid atoms. Electropore formation proceeds even with severe constraints in place, but pore shape and pore formation time are affected. Since lateral and transverse movement of phospholipids may be restricted in cell membranes by covalent attachments to or non-covalent associations with other components of the membrane or to membrane-proximate intracellular or extracellular biomolecular assemblies, these lipid-constrained molecular models point the way to more realistic representations of cell membranes in electric fields. PMID- 29170843 TI - The impact of waiting for intervention on costs and effectiveness: the case of transcatheter aortic valve replacement. AB - OBJECTIVES: The economic crisis in Europe might have limited access to some innovative technologies implying an increase of waiting time. The purpose of the study is to evaluate the impact of waiting time on the costs and benefits of transcatheter aortic valve replacement (TAVR) for the treatment of severe aortic stenosis. METHODS: This is a cost-utility analysis from the perspective of the Spanish National Health Service. Results of two prospective hospital registries (158 and 273 consecutive patients) were incorporated into a probabilistic Markov model to compare quality adjusted life years (QALYs) and costs for TAVR after waiting for 3-12 months, relative to immediate TAVR. We simulated a cohort of 1000 patients, male, and 80 years old; other patient profiles were assessed in sensitivity analyses. RESULTS: As waiting time increased, costs decreased at the expense of lower survival and loss of QALYs, leading to incremental cost effectiveness ratios for eliminating waiting lists of about 12,500 ? per QALY. In subgroup analyses prioritization of patients for whom higher benefit was expected led to a smaller loss of QALYs. Concerning budget impact, long waiting lists reduced spending considerably and permanently. CONCLUSIONS: A shorter waiting time is likely to be cost-effective (considering commonly accepted willingness-to pay thresholds in Europe) relative to 3 months or longer waiting periods. If waiting lists are nevertheless seen as unavoidable due to severe but temporary budgetary restrictions, prioritizing patients for whom higher benefit is expected appears to be a way of postponing spending without utterly sacrificing patients' survival and quality of life. PMID- 29170845 TI - Trapping and resection of cortical MCA mycotic aneurysm in eloquent area. AB - BACKGROUND: Mycotic aneurysms, although well recognized, are relatively rare intracranial vascular pathology. These aneurysms are typically located in distal cortical vessels. When these aneurysms are located in eloquent cerebral territories, they may become challenging to treat. Eloquent location may necessitate intraoperative angiographic evaluation to verify complete aneurysmal occlusion/obliteration and preservation of normal adjacent vasculture. Recently, ICG videoangiography has become a widely used intra-operative adjunct and is an important tool used to assess complete occlusion and vessel patency at the conclusion of clip reconstruction. In this report, we outline the comprehensive and concurrent utilization of both vascular imaging modalities to ensure safe and complete occlusion of a mycotic aneurysm. METHODS: We describe our experience with a patient with left M4, Rolandic, enlarging mycotic aneurysm that was treated in a comprehensive fashion with microsurgery and intra-operative angiography (IA). CONCLUSIONS: ICG videoangiography, in combination with concurrent intraoperative angiography in the setting of complex vascular lesions, may support intraoperative decision-making and provide demonstration of complete occlusion in an immediate fashion. A hybrid operative suite allows for high quality imaging confirming complete resection. PMID- 29170844 TI - Early recognition of aggressive pituitary adenomas: a single-centre experience. AB - BACKGROUND: Pituitary adenomas are usually considered benign tumours, although some of them can exhibit an aggressive behaviour. Patients with clinically aggressive pituitary adenomas are frequently diagnosed with larger masses, and may present an earlier recurrence (or persistence) after surgery. Our aim was to characterise the clinical, histopathological and radiological features of patients with aggressive pituitary adenoma, in order to correlate their clinical behaviour with the response to treatment plan. METHOD: We considered an aggressive pituitary adenoma on the basis of radiological features (size, local invasion), pathological reports (atypical adenoma: MIB-1 >3%, p53 immunoreactivity, increased mitotic activity) and clinical aspects (response to surgery, radiotherapy and medical treatment). RESULTS: Among our cohort of 582 patients, we considered 102 subjects with aggressive pituitary adenomas (18%, 56 male and 46 female): 14 adrenocorticotrophic hormone (ACTH)-secreting, 18 growth hormone (GH)-secreting, 23 prolactin (PRL)-secreting and 47 non-secreting, with a median follow-up of 5 years. In the whole cohort, 75% of patients with aggressive pituitary adenomas presented invasion of surrounding structure, especially GH secreting, PRL-secreting and non-secreting. Besides invasion, their remission rate after surgery, radiotherapy or medical treatment was similar, irrespective of hormonal secretion. Surgery was the most performed treatment (overall remission rate of 24%), especially in those patients with ACTH- or GH-secreting adenoma, and 22% of patients were submitted to radiotherapy, with a remission rate of 45% after a median of 3 years. Two consecutive years of medical treatment, in patients with secreting pituitary adenoma, achieved disease control in 41% of them. Considering pathological reports, 24% of cases were defined as atypical adenomas; radiological characteristics, responses to medical treatment and remission rates were similar among patients with typical and atypical adenoma. CONCLUSIONS: We proposed a new and comprehensive definition of aggressive pituitary adenoma, based upon radiological, clinical and pathological features. In a selected cohort of patients, radiological invasion resulted in the most common marker to describe the aggressive behaviour of pituitary adenoma. Surgery, radiotherapy and medical treatment (the latter only in secreting adenoma) achieved disease control in half of the patients with aggressive adenoma, especially surgery in those with ACTH-oma and medical treatment in those with GH- and PRL-secreting adenoma. Nevertheless, radiological, clinical or atypical features did not affect the outcome.

AB - The mutations of MYH7 (slow skeletal/beta-cardiac myosin heavy chain) are commonly found in familial hypertrophic/dilated cardiomyopathy, and also can cause Laing early-onset distal myopathy (LDM), myosin storage myopathy (MSM), and congenital myopathy with fiber-type disproportion (CFTD). Here we report two cases whose diagnosis was hereditary myopathy according to clinical feature and muscle pathology analysis. High-throughput genomic sequencing (next generation sequencing) was performed to validate the diagnosis. Two MYH7 mutations, p.R1845W and p.E1687del, were identified. p.R1845W was found in a male patient showing weakness of both terminal lower legs without foot drop. Muscle pathology stainings characteristically showed the hyaline body in the intracytoplasmic location. The novel mutation p.E1687del was found in a family with seven patients. The proband showed foot drop, scoliosis, and winged scapula, while his mother only showed mild foot drop and winged scapula. Muscle pathology analysis showed congenital centronucleus myopathy. Both cases only showed muscular disorder and had no cardiomyopathy. This study, for the first time, reports the MYH7 mutations associated with centronucleus myopathy. PMID- 29170850 TI - Carbon monoxide inhibits hemotoxic activity of Elapidae venoms: potential role of heme. AB - Envenomation by hemotoxic enzymes continues to be a major cause of morbidity and mortality throughout the world. With regard to treatment, the gold standard to abrogate coagulopathy caused by these venoms is still the administration of antivenom; however, despite antivenom therapy, coagulopathy still occurs and recurs. Of interest, this laboratory has demonstrated in vitro and in vivo that coagulopathy inducing venom derived from snakes of the family Viperidae exposed to carbon monoxide (CO) is inhibited, potentially by an attached heme. The present investigation sought to determine if venoms derived from snakes of the Elapidae family (taipans and cobras) could also be inhibited with CO or with the metheme inducing agent, O-phenylhydroxylamine (PHA). Assessing changes in coagulation kinetics of human plasma with thrombelastography, venoms from Elapidae snakes were exposed in isolation to CO (five species) or PHA (one specie) and placed in human plasma to assess changes in procoagulant or anticoagulant activity. The procoagulant activity of two taipan venoms and anticoagulant activity of three cobra venoms were significantly inhibited by CO. The venom of the inland taipan was also inhibited by PHA. In sum, these data demonstrate indirectly that the biometal heme is likely bound to these disparate venoms as an intermediary modulatory molecule. In conclusion, CO may not just be a potential therapeutic agent to treat envenomation but also may be a potential modulator of heme as a protective mechanism for venomous snakes against injury from their own proteolytic venoms. PMID- 29170851 TI - The complete chloroplast genome sequence of Dodonaea viscosa: comparative and phylogenetic analyses. AB - The plant chloroplast (cp) genome is a highly conserved structure which is beneficial for evolution and systematic research. Currently, numerous complete cp genome sequences have been reported due to high throughput sequencing technology. However, there is no complete chloroplast genome of genus Dodonaea that has been reported before. To better understand the molecular basis of Dodonaea viscosa chloroplast, we used Illumina sequencing technology to sequence its complete genome. The whole length of the cp genome is 159,375 base pairs (bp), with a pair of inverted repeats (IRs) of 27,099 bp separated by a large single copy (LSC) 87,204 bp, and small single copy (SSC) 17,972 bp. The annotation analysis revealed a total of 115 unique genes of which 81 were protein coding, 30 tRNA, and four ribosomal RNA genes. Comparative genome analysis with other closely related Sapindaceae members showed conserved gene order in the inverted and single copy regions. Phylogenetic analysis clustered D. viscosa with other species of Sapindaceae with strong bootstrap support. Finally, a total of 249 SSRs were detected. Moreover, a comparison of the synonymous (Ks) and nonsynonymous (Ka) substitution rates in D. viscosa showed very low values. The availability of cp genome reported here provides a valuable genetic resource for comprehensive further studies in genetic variation, taxonomy and phylogenetic evolution of Sapindaceae family. In addition, SSR markers detected will be used in further phylogeographic and population structure studies of the species in this genus. PMID- 29170853 TI - Brain Networks are Independently Modulated by Donepezil, Sleep, and Sleep Deprivation. AB - Resting-state connectivity has been widely studied in the healthy and pathological brain. Less well-characterized are the brain networks altered during pharmacological interventions and their possible interaction with vigilance. In the hopes of finding new biomarkers which can be used to identify cortical activity and cognitive processes linked to the effects of drugs to treat neurodegenerative diseases such as Alzheimer's disease, the analysis of networks altered by medication would be particularly interesting. Eleven healthy subjects were recruited in the context of the European Innovative Medicines Initiative 'PharmaCog'. Each underwent five sessions of simultaneous EEG-fMRI in order to investigate the effects of donepezil and memantine before and after sleep deprivation (SD). The SD approach has been previously proposed as a model for cognitive impairment in healthy subjects. By applying network based statistics (NBS), we observed altered brain networks significantly linked to donepezil intake and sleep deprivation. Taking into account the sleep stages extracted from the EEG data we revealed that a network linked to sleep is interacting with sleep deprivation but not with medication intake. We successfully extracted the functional resting-state networks modified by donepezil intake, sleep and SD. We observed donepezil induced whole brain connectivity alterations forming a network separated from the changes induced by sleep and SD, a result which shows the utility of this approach to check for the validity of pharmacological resting state analysis of the tested medications without the need of taking into account the subject specific vigilance. PMID- 29170854 TI - Why childhood-onset type 1 diabetes impacts labour market outcomes: a mediation analysis. AB - AIMS/HYPOTHESIS: Previous studies show a negative effect of type 1 diabetes on labour market outcomes such as employment and earnings later in life. However, little is known about the mechanisms underlying these effects. This study aims to analyse the mediating role of adult health, education, occupation and family formation. METHODS: A total of 4179 individuals from the Swedish Childhood Diabetes Register and 16,983 individuals forming a population control group born between 1962 and 1979 were followed between 30 and 50 years of age. The total effect of having type 1 diabetes was broken down into a direct effect and an indirect (mediating) effect using statistical mediation analysis. We also analysed whether type 1 diabetes has different effects on labour market outcome between the sexes and across socioeconomic status. RESULTS: Childhood-onset type 1 diabetes had a negative impact on employment (OR 0.68 [95% CI 0.62, 0.76] and OR 0.76 [95% CI 0.67, 0.86]) and earnings (-6%, p < 0.001 and -8%, p < 0.001) for women and men, respectively. Each of the mediators studied contributed to the total effect with adult health and occupational field accounting for the largest part. However, some of the effect could not be attributed to any of the mediators studied and was therefore likely related to other characteristics of the disease that hamper career opportunities. The effect of type 1 diabetes on employment and earnings did not vary significantly according to socioeconomic status of the family (parental education and earnings). CONCLUSIONS/INTERPRETATION: A large part of the effect of type 1 diabetes on the labour market is attributed to adult health but there are other important mediating factors that need to be considered to reduce this negative effect. PMID- 29170855 TI - Laparoscopic and robotic surgery for stone disease. AB - Treatment for stone disease has evolved drastically during the past 3-4 decades. Ureteroscopy, percutaneous nephrolithotomy along with SWL, provides the means to treat practically all urinary tract stones with minimal invasion to the patients. However, for complex stone case scenarios where open surgery is being considered, a less invasive and better tolerated option such as laparoscopy (robot assisted or not) can be performed. The present manuscript reviews role of laparoscopic and robotic surgery in treating urinary tract stones. PMID- 29170852 TI - T cell subsets: an integral component in pathogenesis of rheumatic heart disease. AB - Acute rheumatic fever (ARF) is a consequence of pharyngeal infection of group A streptococcal (GAS) infection. Carditis is the most common manifestation of ARF which occurs in 30-45% of the susceptible individuals. Overlooked ARF cases might further progress towards rheumatic heart disease (RHD) in susceptible individuals, which ultimately leads to permanent heart valve damage. Molecular mimicry between streptococcal antigens and human proteins is the most widely accepted theory to describe the pathogenesis of RHD. In the recent past, various subsets of T cells have been reported to play an imperative role in the pathogenesis of RHD. Alterations in various T cell subsets, viz. Th1, Th2, Th17, and Treg cells, and their signature cytokines influence the immune responses and are associated with pathogenesis of RHD. Association of other T cell subsets (Th3, Th9, Th22, and TFH) is not defined in context of RHD. Several investigations have confirmed the up-regulation of adhesion molecules and thus infiltration of T cells into the heart tissues. T cells secrete both Th type 1 and type 2 cytokines and these auto-reactive T cells play a key role in progression of heart valve damage. In this review, we are going to discuss about the role of T cell subsets and their corresponding cytokines in the pathogenesis of RHD. PMID- 29170856 TI - Robot-assisted flexible ureteroscopy: an update. AB - The role of flexible ureteroscopy (FURS) in the management of nephrolithiasis has increased due to the improved armamentarium. However, FURS still represents a challenging technique limiting its diffusion. Similar to previous experiences in laparoscopy, recently developed robotic devices may significantly compensate for the ergonomic deficiencies of FURS. Based on a short description of the history of robotic devices for laparoscopy, this article summarizes all current developments of robotic FURS. In 2008, robotic FURS was first reported using the Sensei-Magellan system designed for interventional cardiology. However, with this device the ureteroscope was only passively manipulated, which represented the main reason why this project has been discontinued after 18 clinical cases. Avicenna RoboflexTM was especially developed for FURS. It consists of a surgeon's console and manipulator of a flexible ureterorenoscope. The console provides an adjustable seat with armrests and two manipulators of the endoscope: the right wheel enables deflection and the left horizontal joystick allows rotation as well as advancing and retracting the instrument. The speed of rotation and advancement can be regulated at the screen of the console. Using the IDEAL system for evaluation of new robotic devices, safety and efficacy of the system could be demonstrated in two multi-centric studies providing significant improved ergonomics for the surgeon (IDEAL stage 1 and 2). Future studies are necessary to determine the final role of robotic FURS. PMID- 29170857 TI - Comorbidities and medication use in patients with a recent clinical fracture at the Fracture Liaison Service. AB - : In this cross-sectional study, two-thirds of Fracture Liaison Service (FLS) patients had comorbidities and medications associated with increased bone- or fall-related fracture risk. Bone-related and fall-related fracture risk (BRR and FRR) were associated with age and fracture type, but not with gender or BMD. Systematic evaluation of these factors leads to a more profound assessment in FLS care. INTRODUCTION: This study is a systematic evaluation of comorbidities and medications associated with increased fracture risk in patients aged 50-90 years with a recent fracture visiting the FLS. METHODS: In this cross-sectional cohort study, comorbidities were classified according to ICD-10 and medications according to the Anatomic Therapeutic Chemical (ATC) classification and further categorized into those associated BRR and FRR. RESULTS: Of 1282 patients (72% women; 65 +/- 9 years), 53% had at least one BRR, 46% had at least one FRR, and 66% at least one BRR and/or FRR. At least one BRR, as well as at least one FRR were associated with age, BMI, and fracture type, but not with gender or BMD. The proportion of patients with only BRR (+/- 20%) or only FRR (+/- 10%) was similar among ages, gender, BMI, fracture type, and BMD. The combination of at least one BRR and at least one FRR was significantly associated with age, BMI, and major fractures, but not with gender or BMD. CONCLUSION: Comorbidities and medications associated with increased fracture risk are present in two-thirds of patients visiting the FLS. In addition, the proportion of patients having a combination of BRR and FRR increased significantly with age, BMI, and fracture severity. This indicates that systematic evaluation of these factors is important for a more profound assessment of subsequent fracture risk in FLS care. PMID- 29170858 TI - Impact of choice of future climate change projection on growth chamber experimental outcomes: a preliminary study in potato. AB - Understanding the impacts of climate change on agriculture is essential to ensure adequate future food production. Controlled growth experiments provide an effective tool for assessing the complex effects of climate change. However, a review of the use of climate projections in 57 previously published controlled growth studies found that none considered within-season variations in projected future temperature change, and few considered regional differences in future warming. A fixed, often arbitrary, temperature perturbation typically was applied for the entire growing season. This study investigates the utility of employing more complex climate change scenarios in growth chamber experiments. A case study in potato was performed using three dynamically downscaled climate change projections for the mid-twenty-first century that differ in terms of the timing during the growing season of the largest projected temperature changes. The climate projections were used in growth chamber experiments for four elite potato cultivars commonly planted in Michigan's major potato growing region. The choice of climate projection had a significant influence on the sign and magnitude of the projected changes in aboveground biomass and total tuber count, whereas all projections suggested an increase in total tuber weight and a decrease in specific gravity, a key market quality trait for potato, by mid-century. These results demonstrate that the use of more complex climate projections that extend beyond a simple incremental change can provide additional insights into the future impacts of climate change on crop production and the accompanying uncertainty. PMID- 29170859 TI - Patients' Reported Usage of Weight Management Skills Following Bariatric Surgery. AB - Little is known about which specific weight management skills bariatric patients find most and least valuable. Participants completed a measure assessing their usage of weight management skills at a follow-up appointment one or more years after undergoing bariatric surgery. Decreased usage of skills was associated with unsuccessful weight outcome, defined as losing less than 50% of excess weight, as well as weight regain. Weighing regularly was the skill selected most often by successful participants as helpful, and was chosen by a significantly smaller percentage of unsuccessful participants and those who regained a clinically significant amount of weight. A majority of both successful and unsuccessful participants indicated that they had discontinued food journaling. Weighing regularly may be perceived as a more useful method of self-monitoring. PMID- 29170860 TI - gamma-Glutamyltransferase Fractions in Obese Subjects with Type 2 Diabetes: Relation to Insulin Sensitivity and Effects of Bariatric Surgery. AB - BACKGROUND/OBJECTIVES: Gamma-glutamyltranspeptidase (GGT) levels are an independent risk marker for the development of type 2 diabetes (T2DM). We investigated the relationship between the newly identified serum GGT fractions and glucose metabolism in obese subjects before and after bariatric surgery. SUBJECTS/METHODS: Twenty-nine T2DM subjects, wait-listed for Roux-en-Y gastric bypass (RYGB; n = 21) or laparoscopic sleeve gastrectomy (LSG; n = 8), received a 5-h mixed meal test before (T0), 15 days (T15), and 1 year after surgery (T365). Insulin sensitivity was assessed by the OGIS index and beta-cell function by C peptide analysis; fractional GGT (b-, s-, m-, and f-GGT) analysis was performed by gel-filtration chromatography. RESULTS: At T15, total GGT activity decreased by 40% after LSG (p = 0.007) but remained unchanged after RYGB. At T365, all patients showed a reduction in total GGT, in particular b-GGT (>= 60%) and m-GGT (>= 50%). In patients with biopsy-proven steatohepatitis (n = 10), total, b-, s-, and m-GGT fractions at T0 were significantly higher than in patients with low grade steatosis (p = 0.016, 0.0003, and 0.005, respectively); at T365, there was a significant fall in total GGT as well as in each fraction in both groups. In a multiple regression model, b-GGT was the only fraction related to insulin sensitivity (p = 0.016; beta coeff. = - 14.0) independently of BMI, fasting glucose, and triglycerides. CONCLUSIONS: While GGT activity is generally associated with impaired glucose metabolism, fractional GGT analysis showed that the b-GGT fraction specifically and independently tracks with insulin resistance. PMID- 29170861 TI - Incidence of peripheral nerve injury during shoulder arthroplasty when motor evoked potentials are monitored. AB - To report the incidence of clinically detectable nerve injuries when utilizing transcranial electrical motor evoked potentials (MEPs) during shoulder arthroplasty. A retrospective review of patients undergoing shoulder arthroplasty with continuous IONM was performed. The criteria for nerve alerts was an 80% amplitude reduction in MEPs. The primary outcome measure was post-operative clinically detectable nerve deficit. An additional retrospective analysis on a subset of cases using an all-or-none (100% amplitude reduction) criterion applied to the deltoid was performed. Two hundred eighty four arthroplasty cases were included. There were no permanent post-operative nerve injuries and two transient nerve injuries (0.7%). MEP alerts occurred in 102 cases (36.2%). Nineteen (6.7%) cases did not have signals return above alert threshold at closure. These cases were significantly associated with post-operative nerve injury (p = 0.03). There were no false negatives, making sensitivity 100% and specificity was 93.9%. In the subset of cases in which an all-or-none criterion was retrospectively applied to just the deltoid, MEP alerts occurred in just 17.9% of cases; specificity improved to 98.0%. We conclude that utilization of the real-time diagnostic MEP data during shoulder arthroplasty aids surgeons in decision making regarding impending peripheral nerve injuries. PMID- 29170862 TI - Editorial on EMC 2017 special issue. PMID- 29170863 TI - Strontium Promotes Transforming Growth Factors beta1 and beta2 Expression in Rat Chondrocytes Cultured In Vitro. AB - The transforming growth factors beta1 (TGF-beta1) and TGF-beta2, as two distinct homodimers of TGF-beta superfamily, involve in chondrocyte growth and differentiation. Emerging evidence has implied that strontium (Sr) plays an important role in the bone formation and resorption, and has strong effects on stimulating human cartilage matrix formation in vitro. However, the direct effects of Sr on TGF-beta1 and TGF-beta2 expressions in chondrocytes are not entirely clear. The purpose of this study was to evaluate the influence of different Sr concentrations on the expression of TGF-beta1 and TGF-beta2 in rat chondrocytes in vitro. Chondrocytes were isolated from Wistar rat articular by enzymatic digestion. Strontium chloride hexahydrate (SrCl2.6H2O) was used as a Sr source in this study. Sr was added to the culture solution at final concentrations of 0, 0.5, 1.0, 2.0, 5.0, 20.0, and 100 MUg/mL. After 72 h of continuous culture, TGF-beta1 and TGF-beta2 mRNA abundance and protein expression levels in the chondrocytes were determined by real-time polymerase chain reaction (real-time PCR) and Western blot, respectively. The results showed that TGF-beta1 and TGF-beta2 expressions in chondrocytes increased dose-dependently with Sr concentration. The mRNA abundance of TGF-beta1 and TGF-beta2 were markedly higher than those observed for control (P < 0.01) when the Sr-treated concentration exceeded 1.0 and 5.0 MUg/mL, respectively. The TGF-beta1 and TGF-beta2 protein expression levels were extremely significantly higher than those in the control group (P < 0.01) at above 5.0 MUg/mL Sr-treatment. These results indicated that Sr could involve in the chondrocytes metabolism via regulating TGF-beta1 and TGF beta2 signalling. PMID- 29170864 TI - Risk of Malignancy in a Nationwide Cohort of Elderly Inflammatory Bowel Disease Patients. AB - BACKGROUND: Management of elderly inflammatory bowel disease (IBD) patients (>= 65 years of age) is complicated due to many factors, including a higher risk of cancer, which may impact therapeutic decisions. OBJECTIVE: The aim of this study was to determine the risk of cancer among elderly IBD patients compared with younger IBD patients. Additionally, the absolute risk of malignancy and factors contributing to it were evaluated, and therapeutic patterns among the elderly were assessed. METHODS: This retrospective cohort study extracted data from the Truven Health Analytics MarketScan(r) database. Among adult IBD patients who were free of cancer before starting on corticosteroids, immunomodulators, or biologics, a Cox model for time to cancer was fitted that adjusted for several covariates, including time-dependent treatment. Baseline results were evaluated by age group, as were the incidence of cancer and the distribution of cancer subtypes. RESULTS: The elderly IBD cohort (n = 8788) had a higher prevalence of cancer and several other ailments before starting treatment, relative to the younger IBD cohort aged 18-64 years (n = 54,971). During follow-up, the elderly IBD cohort experienced a higher incidence of malignancy, confirmed by a hazard ratio (HR) of 3.04 (95% confidence interval [CI] 2.71-3.41) from the Cox model fit. The risk of cancer was also significantly associated with male sex (HR 0.82 female), duration of disease (HR 1.08), several comorbidities and corticosteroid use (HR 1.35), but not with the use of immunomodulators or biologics. Non Hodgkin's lymphoma, urinary tract malignancy, and prostate, lung, and female breast cancers were observed more commonly in this elderly IBD cohort when compared with the same age group in the Surveillance, Epidemiology, and End Results (SEER) database. CONCLUSIONS: The elderly with IBD have a higher risk of malignancy when compared with younger IBD patients and the general age-matched population, with certain cancers being more common among these patients.

AB - Previous research has shown how filial piety is strong among people of Iranian background and that traditional Iranian culture result in most families' preferring to care for their elderly (and sick) family members at home. While acknowledging this, this article highlights what living in diaspora could mean in terms of cultural adaption and changing family values. By interviewing people with Iranian background living in Sweden (n = 20), whom all have been former primary caregivers to a relative living with dementia, we are able to show how the decision to cease caregiving at home is taken, and what underlying factors form the basis for such decision. Results indicate that although the existence of a Persian profiled dementia care facility is crucial in the making of the decision, it is the feeling of 'sheer exhaustion' that is the main factor for ceasing care at home. And, we argue, the ability to make such a decision based upon 'being too tired' must be understood in relation to transition processes and changes in lifestyle having an affect upon cultural values in relation to filial piety. Because, at the same time the changes on cultural values might not change accordingly among the elderly who are the ones moving into residential care, resulting in them quite often being left out of the actual decision. PMID- 29170866 TI - Registration of angiographic image on real-time fluoroscopic image for image guided percutaneous coronary intervention. AB - PURPOSE: In percutaneous coronary intervention (PCI), cardiologists must study two different X-ray image sources: a fluoroscopic image and an angiogram. Manipulating a guidewire while alternately monitoring the two separate images on separate screens requires a deep understanding of the anatomy of coronary vessels and substantial training. We propose 2D/2D spatiotemporal image registration of the two images in a single image in order to provide cardiologists with enhanced visual guidance in PCI. METHODS: The proposed 2D/2D spatiotemporal registration method uses a cross-correlation of two ECG series in each image to temporally synchronize two separate images and register an angiographic image onto the fluoroscopic image. A guidewire centerline is then extracted from the fluoroscopic image in real time, and the alignment of the centerline with vessel outlines of the chosen angiographic image is optimized using the iterative closest point algorithm for spatial registration. RESULTS: A proof-of-concept evaluation with a phantom coronary vessel model with engineering students showed an error reduction rate greater than 74% on wrong insertion to nontarget branches compared to the non-registration method and more than 47% reduction in the task completion time in performing guidewire manipulation for very difficult tasks. Evaluation with a small number of experienced doctors shows a potentially significant reduction in both task completion time and error rate for difficult tasks. The total registration time with real procedure X-ray (angiographic and fluoroscopic) images takes [Formula: see text] 60 ms, which is within the fluoroscopic image acquisition rate of 15 Hz. CONCLUSIONS: By providing cardiologists with better visual guidance in PCI, the proposed spatiotemporal image registration method is shown to be useful in advancing the guidewire to the coronary vessel branches, especially those difficult to insert into.

AB - Three-dimensional (3D) printing is an emerging technique in the field of biomedical engineering and electronics. This paper presents a novel biofabrication method of implantable carbon electrodes with several advantages including fast prototyping, patient-specific and miniaturization without expensive cleanroom. The method combines stereolithography in additive manufacturing and chemical modification processes to fabricate electrically conductive carbon electrodes. The stereolithography allows the structures to be 3D printed with very fine resolution and desired shapes. The resin is then chemically modified to carbon using pyrolysis to enhance electrochemical performance. The electrochemical characteristics of 3D printing carbon electrodes are assessed by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The specific capacitance of 3D printing carbon electrodes is much higher than the same sized platinum (Pt) electrode. In-vivo electromyography (EMG) recording, 3D printing carbon electrodes exhibit much higher signal-to noise ratio (40.63 +/- 7.73) than Pt electrodes (14.26 +/- 6.83). The proposed biofabrication method is envisioned to enable 3D printing in many emerging applications in biomedical engineering and electronics. PMID- 29170868 TI - Levofloxacin for febrile neutropenia prophylaxis in acute myeloid leukemia patients associated with reduction in hospital admissions. AB - PURPOSE: The purpose of this study is to evaluate the efficacy and safety of prophylactic oral levofloxacin in acute myeloid leukemia (AML) patients after receiving consolidation chemotherapy to prevent febrile neutropenia. METHODS: We conducted a retrospective chart review of 50 AML patients who were prescribed levofloxacin and 50 AML patients who were not prescribed levofloxacin post consolidation chemotherapy between June 2006 and August 2013 at a tertiary academic medical center. The primary outcome of this study was to evaluate the effectiveness of levofloxacin in preventing hospital readmission due to febrile neutropenia. Secondary outcomes evaluated the safety of this therapy, including the rate of Clostridium difficile-associated diarrhea (CDAD) within 30 days from discharge of receiving consolidation chemotherapy and rate of fluoroquinolone resistance in positive bacterial cultures. RESULTS: Hospital readmission due to febrile neutropenia after the first consolidation cycle occurred in 42% of patients prescribed levofloxacin, as compared to 72% that were not prescribed levofloxacin (p = 0.002). This was also significantly reduced when levofloxacin was prescribed after all consolidation cycles (51.4 vs. 67%, p = 0.023). CDAD did not occur in any patient prescribed levofloxacin after the first cycle, compared to one case in those not prescribed levofloxacin. Evaluation of the impact on fluoroquinolone resistance was limited due to a paucity of fluoroquinolone susceptibilities reported. CONCLUSIONS: Prescribing oral levofloxacin post consolidation chemotherapy in AML patients is associated with a reduction in febrile neutropenia. Further research is required to identify the impact on fluoroquinolone resistance and risk of CDAD.

PMID- 29170871 TI - The diagnostic role of PTEN and ARID1A in serous effusions. AB - The aim of this study was to analyze the diagnostic role of PTEN and ARID1A in effusion cytology. Effusions (n = 279), consisting of 226 carcinomas (70 ovarian, 64 breast, 36 lung, and 15 uterine corpus carcinomas; 41 carcinomas of other origin) and 53 malignant mesotheliomas, were analyzed for PTEN and ARID1A expression using immunohistochemistry. PTEN was preserved in 166 (59%) tumors, partially lost in 38 (14%), and absent in 75 (27%), with lower expression in malignant mesotheliomas compared to carcinomas, though not significantly (p = 0.084). ARID1A was preserved in 243 (88%) tumors, partially lost in 18 (6%), and absent in 18 (6%). The majority of tumors with absent ARID1A were ovarian carcinomas, predominantly of clear cell or low-grade serous type. Reactive mesothelial cells in carcinoma specimens were uniformly positive for both proteins. ARID1A mutation analysis showed no mutations in eight analyzed specimens negative by immunohistochemistry. Loss of PTEN and ARID1A expression is highly specific for malignancy in effusion pathology. Loss of PTEN is not informative of organ of origin, whereas absence of ARID1A should raise suspicion of an ovarian primary. PMID- 29170872 TI - New insights from molecular phylogenetics of amoebophagous fungi (Zoopagomycota, Zoopagales). AB - Amoebophagous fungi are represented in all fungal groups: Basidiomycota, Ascomycota, Zygomycota, and Chytridiomycota. The amoebophagous fungi, within the zygomycota (Zoopagales, Zoopagomycota), mainly affect naked amoebae as ectoparasites or endoparasites. It is rather difficult to isolate members of the Zoopagales, because of their parasitic lifestyle, and to bring them into culture. Consequently, gene sequences of this group are undersampled, and its species composition and phylogeny are relatively unknown. In the present study, we were able to isolate amoebophagous fungi together with their amoeba hosts from various habitats (moss, pond, bark, and soil). Altogether, four fungal strains belonging to the genera Acaulopage and Stylopage plus one unidentified isolate were detected. Sequences of the 18S rDNA and the complete ITS region and partial 28S (LSU) rDNA were generated. Subsequent phylogenetic analyses showed that all new isolates diverge at one branch together with two environmental clonal sequences within the Zoopagomycota. Here, we provide the first molecular characterization of the genus Stylopage. Stylopage is closely related to the genus Acaulopage. In addition, taxonomy and phylogeny of amoebophagous fungi and their ecological importance are reviewed based on new sequence data, which includes environmental clonal sequences. PMID- 29170873 TI - Multispecies blow fly myiasis combined with hypothermia in a man assumed to be dead. AB - We describe the case of a man who was found with severe hypothermia and advanced myiasis involving five species of blow flies, which eventually led to a transtibial amputation of the man's right leg. A case of such a heavy and species rich infestation with fly larvae in an urban environment is extraordinary and has, to our knowledge, never been described so far. Best practice in cases such as this one demands accurate species identification not only to ensure appropriate treatment and pest management but also, from a forensic point of view, to explore the possibility of third-party responsibility. The cooperation between physicians and forensic entomologists is highlighted. PMID- 29170874 TI - Daily variation of NTBC and its relation to succinylacetone in tyrosinemia type 1 patients comparing a single dose to two doses a day. AB - INTRODUCTION: In hereditary tyrosinemia type 1 (HT1) patients, the dose of NTBC that leads to the absence of toxic metabolites such as succinylacetone (SA) is still unknown. Therefore, the aims of this study were to investigate the variation and concentrations of 2-(2-nitro-4-trifluormethyl-benzyl)-1,3 cyclohexanedione (NTBC) during the day in relation to the detection of SA, while comparing different dosing regimens. METHODS: All patients were treated with NTBC (mean 1.08 +/- 0.34 mg/kg/day) and a low phenylalanine-tyrosine diet. Thirteen patients received a single dose of NTBC and five patients twice daily. Home bloodspots were collected four times daily for three consecutive days measuring NTBC and SA concentrations. Statistical analyses were performed by using mixed model analyses and generalized linear mixed model analyses to study variation and differences in NTBC concentrations and the correlation with SA, respectively. RESULTS: NTBC concentrations varied significantly during the day especially if NTBC was taken at breakfast only (p = 0.026), although no significant difference in NTBC concentrations between different dosing regimens could be found (p = 0.289). Momentary NTBC concentrations were negatively correlated with SA (p < 0.001). Quantitatively detectable SA was only found in subjects with once daily administration of NTBC and associated with momentary NTBC concentrations <44.3 MUmol/l. DISCUSSION: NTBC could be less stable than previously considered, thus dosing NTBC once daily and lower concentrations may be less adequate. Further research including more data is necessary to establish the optimal dosing of NTBC. PMID- 29170875 TI - Long-term pharmacodynamic effects of Ticagrelor versus Clopidogrel in fibrinolytic-treated STEMI patients undergoing early PCI. AB - The long-term pharmacodynamic effects of Ticagrelor versus Clopidogrel in patients undergoing early percutaneous coronary intervention (PCI) after fibrinolytic therapy is unknown. From May 2014 to August 2016, 212 patients undergoing PCI within 24 h of Tenecteplase (TNK), Aspirin, and Clopidogrel for ST elevated myocardial infarction (STEMI) were randomized at four Canadian sites to receive additional Clopidogrel or Ticagrelor initiated prior to PCI. The platelet reactivity units (PRU) were measured with the VerifyNow Assay before study drug administration (baseline), at 4 and 24 h post PCI, and follow-up appointment. A mixed-model analysis with time as the repeated measure and drug as the between subjects factor was calculated using 2 separate 1 * 4 ANOVAs, with students t tests used to compare drugs within each time point. Complete clinical follow-up data (median 115.0 days; IQR 80.3-168.8) was available in 50 patients (23.6%) randomized to either Clopidogrel (n = 23) or Ticagrelor (n = 27). Analyses revealed significant decreases in PRU from baseline to 4 h (261.4 vs. 71.7; Mdiff = - 189.7; p < 0.001) to 24 h (71.7 vs. 27.7; Mdiff = - 44.0; p < 0.001) to end of follow-up (27.7 vs.17.9; Mdiff = - 9.9. p = 0.016) for those randomized to Ticagrelor and significant decreases in PRU only from baseline to 4 h (271.3 vs. 200.8; Mdiff = - 70.5, p = < 0.001) in patients receiving Clopidogrel, and a significantly greater proportion of patients with adequate platelet inhibition (PRU < 208) on long-term follow-up (Clopidogrel, 82.6% vs. Ticagrelor, 100.0%; p = 0.038). Our results demonstrate that in patients undergoing PCI within 24 h of fibrinolysis for STEMI, Ticagrelor provides prolonged platelet inhibition compared with Clopidogrel. PMID- 29170876 TI - Venous thromboembolism in assisted reproductive technologies: comparison between unsuccessful versus successful cycles in an Italian cohort. AB - Pregnancies after assisted reproductive technologies (ART) have been associated with an increased risk of venous thromboembolism (VTE). On the contrary, the magnitude of this risk in unsuccessful ART cycles (not resulting in a clinical pregnancy) has not yet been clearly defined. In this study, we evaluated the incidence of VTE in unsuccessful cycles and compared it with that recorded in successful cycles in the same study population. From a cohort of 998 women consecutively referred by local Fertility Clinics to our Atherosclerosis and Thrombosis Unit (April 2002-July 2011), we identified and included women with at least one cycle of ovarian stimulation and a negative history for VTE. Overall, 661 women undergone 1518 unsuccessful and 318 successful cycles of ovarian stimulation, respectively, were analysed. VTE events occurred in 2/1518 (1.30/00) unsuccessful cycles compared with 3/318 (9.40/00) successful cycles, (Two-tailed Fisher exact test, p = 0.04, OR 0.14, 95% CI 0.02-1.02). Both cases observed in unsuccessful cycles were isolated pulmonary embolism occurred after OHSS; no antithrombotic prophylaxis had been prescribed. At logistic regression analysis, the occurrence of successful cycle and BMI were significantly and independently associated with the occurrence of VTE with an OR of 13.94 (95% CI 1.41-137.45) and 1.23 (95% CI 1.01-1.49), respectively. VTE incidence is significantly lower in unsuccessful cycles as compared to that of successful ones. However, although rare, thrombotic risk during ovarian stimulation cannot be excluded and, when it occurs, can be life-threatening. Therefore, particular attention should be paid to these women, independently of ART outcome. PMID- 29170877 TI - Oral anticoagulant dosing, administration, and storage: a cross-sectional survey of Canadian health care providers. AB - Direct oral anticoagulant (DOAC) use is increasing worldwide. However, if not taken or prescribed correctly, DOACs have serious side effects. It is crucial that healthcare providers (HCPs) offer patients accurate information and counselling around DOACs, to optimize safe and effective use. To assess knowledge around oral anticoagulant indication, dosing, storage, and administration, an electronic survey was distributed to HCPs across Canada from June to August 2017, with 18 questions on the practical use of oral anticoagulants. A total of 191 responses were received: 100 from nurse practitioners, 42 from pharmacists, 27 from Hematologists, 5 from Thrombosis specialists, 4 from internists, 9 from residents and fellows, and 2 each from family physicians and registered nurses. Only 51 (26.7%) of the respondents correctly identified all the approved indications for warfarin and 4 DOACs. Only 101 (52.9%) correctly identified that DOACs are not approved for treatment of heparin-induced thrombocytopenia, cerebral sinus venous thrombosis, or mechanical prosthetic valves. 112 (58.6%) felt comfortable or very comfortable prescribing oral anticoagulants. Half of the respondents knew that dabigatran should not be crushed, however only 85 (44.5%) knew that it should not be exposed to moisture. 94 (49%) knew that higher dose rivaroxaban should be taken with food. The results of our study demonstrate that there are important knowledge gaps around HCPs' practical understanding of oral anticoagulants. Future research should focus on educational interventions to improve HCPs' knowledge around indications, dosing, storage, and administration, with the goal of enhancing patient safety. PMID- 29170878 TI - Addressing Relationship Health Needs in Primary Care: Adapting the Marriage Checkup for Use in Medical Settings with Military Couples. AB - The overall objective of this study was to pilot the Marriage Checkup (MC), a brief intervention for enhancing marital resiliency tailored to a military population, for use by internal behavioral health consultants (IBHCs) working in an integrated primary care clinic. The MC was revised to fit into the fast-paced environment of primary care (e.g., streamlined to fit within three 30-min appointments), and military-relevant material was added to the content. IBHCs working in primary care were then trained to offer the intervention. Thirty participants were enrolled in the study and completed a relationship checkup and one-month follow-up questionnaires. Analysis of post-test and one-month follow-up data showed statistically significant improvements in participants' marital health compared to pre-treatment. The MC intervention appeared to be well received by both couples and IBHCs. PMID- 29170879 TI - Factors influencing recurrence and progression of Dupuytren's disease treated by Collagenase Clostridium histolitycum. AB - AIM OF THE STUDY: The purpose of this study was to determine the recurrence rate, possible adverse reactions and factors influencing recurrence and progression of Dupuytren's disease (DD) treated with Collagenase from Clostridium histolyticum (CCH). METHOD: This was a prospective study of 71 patients with DD treated with CCH from 2011 to February 2013, with a minimum follow-up period of four years. Clinical, functional, patient satisfaction, drug safety and factors influencing recurrence and disease progression were evaluated. RESULTS: In all patients, the rupture of the cord was achieved after the injection, reducing joint contracture. In five patients (7%) we verified the existence of disease recurrence during the follow-up. In 11 patients (15.5%) there was a disease progression. Three patients have been surgically operated on, without added surgery difficulty; the rate of recurrence and progression was higher in grades III and IV of Tubiana, in proximal interphalangeal (PIP) punctures, and was earlier in patients younger than 60 years. DISCUSSION: No serious local complications or general complications were observed with this method. The recurrence of DD, following criteria of Felici, is mainly observed in young patients with greater severity of the disease and at the PIP level. Progression is influenced by the same factors. Patients operated on after recurrence have no added difficulty in the surgical technique, as it has also been published in other studies. CONCLUSIONS: Patients with the lowest rates of recurrence and progression were those with a single cord in the metacarpophalangeal (MCP), a grade II of Tubiana, and were older than 60 years. PMID- 29170880 TI - Fingernail and toenail clippings as a non-invasive measure of chronic cortisol levels in adult cancer survivors. AB - PURPOSE: Cancer survivors are at greater risk of comorbidities and functional decline due to physiological and psychological stress which can be measured by salivary cortisol. If saliva is used, multiple samples must be collected to accurately quantify long-term stress; however, fingernail (FN) and toenail (TN) clippings offer an opportunity to measure retrospective cortisol levels in a non invasive manner. METHODS: Three sets of FN and TN clippings were collected at 12 month intervals in conjunction with saliva samples from cancer survivors (n = 109) participating in two clinical trials. FN and TN samples were stored at room temperature (RT); a subset underwent additional processing and freezing before analysis. Cortisol levels were determined via enzyme immunoassay, and correlation coefficients were generated to determine overall correspondence of the individual measures. RESULTS: Matched RT and frozen samples were highly correlated for TN (r = 0.950, p = 5.44 * 10-37) and FN (r = 0.784, p = 1.05 * 10-10). Correlations between RT FN and TN were statistically significant (r = 0.621, p = 3.61 * 10- 17), as were frozen FN and TN (r = 0.310, p = 0.0283). RT, but not frozen TN and FN correlated with salivary cortisol (r = 0.580, p = 1.65 * 10- 16 and r = 0.287, p = 0.00042 for TN and FN, respectively). CONCLUSIONS: FN and TN cortisol levels correlate with salivary cortisol in adult cancer survivors and may offer a less invasive and convenient means for measuring chronic cortisol levels. PMID- 29170881 TI - Factors related to longitudinal adherence in colorectal cancer screening: qualitative research findings. AB - BACKGROUND: The effectiveness of screening in colorectal cancer prevention depends on sustained participation rates. The objective of this study was to explore factors related to the longitudinal adherence of screening behavior in the context of a biennial population-based cancer screening program. METHODS: Eight focus groups were conducted with individuals who were invited two or three consecutive times to a population-based colorectal cancer screening program using a fecal occult blood test and who agreed to participate in the program at least once (n = 45). The criteria used to select the study members included adherence to fecal occult blood test maintenance, factors regarding their initial participation in the colorectal cancer screening, sex, and contextual educational level. RESULTS: The participants expressed a high level of satisfaction with the program; however, they showed a low level of understanding with respect to cancer screening. Consulting a general practitioner was cited by all participants as an important factor that mediated their final decision or influenced their behavior as a whole with regard to the program. Fear played a different role in the screening behavior for regular and irregular adherent participants. In the adherent participants, fear facilitated their continued participation in the screening program, whereas for the irregular participants, fear led them to avoid or refuse further screening. Having a close person diagnosed with colorectal cancer was a facilitator for the regular adherent participants. The irregular adherent participants showed some relaxation with respect to screening after a negative result and considered that further screening was no longer necessary. CONCLUSION: Considering the importance of primary healthcare professionals in the decision regarding sustained participation, it is important to better engage them with cancer screening programs, as well as improve the communication channels to provide accurate and balanced information for both health professionals and individuals. PMID- 29170882 TI - The association of unemployment with glucose metabolism: a systematic review and meta-analysis. AB - OBJECTIVES: Unemployment has been linked with poor health. We hypothesized that being unemployed is associated with disorders of glucose metabolism and performed a systematic review and meta-analysis of the literature to ascertain the relationship. METHODS: We searched the databases of Scopus, Medline Ovid and Web of Science for population-based original studies for past 20 years. Random effects meta-analyses were used to estimate odds ratios (OR) with 95% confidence intervals (CI) for prediabetes and type 2 diabetes among the unemployed as compared to those employed, separately for men and women when possible. RESULTS: Out of 981 articles found, 12 articles were included in the systematic review and eight articles in the meta-analyses. Unemployment was associated with 1.6-fold odds for prediabetes (OR 1.58; 95% CI 1.07-2.35), and 1.7-fold odds for type 2 diabetes (OR 1.72; 95% CI 1.14-2.58) in the total sample. The corresponding associations for type 2 diabetes were also found stratified for men (OR 1.53; 95% CI 1.47-1.60) and women (OR 1.60; 95% CI 1.33-1.92). CONCLUSIONS: Unemployment is associated with prediabetes and type 2 diabetes, global concerns of public health with potential for prevention. PMID- 29170883 TI - Identification of key gene modules and pathways of human breast cancer by co expression analysis. AB - BACKGROUND: Breast cancer is the most common and aggressive tumor causing injury to women world wide. Although gene expression analysis had been performed previously, systemic co-expression analysis for this cancer is still lacking to date. We attempted to identify the critical modules of breast cancer. METHODS: Co expression modules were established with the help of WGCNA and the interactions among them were performed by R language. Biological process and pathways analysis of co-expression genes were figured out by GO and KEGG functional enrichment analysis using DAVID dataset. RESULTS: In this study, expression data of 4,000 genes from 136 samples with breast cancer was used for the establishment of co expression modules. And nine modules were identified. There was much higher scale independence among different modules by interactions analysis. Moreover, there was an obvious difference in adjacency degree among different modules. The most enriched pathways as immune response and ubiquitin-mediated proteolysis were identified as the most critical modules of breast cancer by GO and KEGG enrichment analysis. CONCLUSION: Our result demonstrated that immune response and ubiquitin-mediated proteolysis could serve as prognostic and predictive markers for the occurrence of breast cancer, providing evidence for further analysis in the prognosis and treatment of breast cancer. PMID- 29170884 TI - Is retrograde blood flow of aortic isthmus useful for the prenatal screening of coarctation of the aorta by fetal color Doppler echocardiography? A preliminary study. AB - PURPOSE: To validate the relationship between retrograde blood flow in the aortic isthmus (AoI-R) by color Doppler in fetal echocardiography and postnatal coarctation of the aorta (CoA) diagnosed as isthmus narrowing. METHODS: This was a retrospective study of 22 cases of prenatally suspected simple CoA or CoA with small ventricular septum defect based on fetal echocardiography performed by pediatric cardiologists in our hospital. Gestational age at the first detection of AoI-R and the optimal cut-off value for the prediction of postnatal CoA were mainly evaluated according to the postnatal diagnosis of CoA. RESULTS: All 22 cases had AoI-R prenatally, and nine of them (40.9%) had isthmus narrowing and were diagnosed as having CoA immediately after birth. The gestational age at the first detection of AoI-R was significantly lower in cases with postnatal CoA than in those without (average 34.4 weeks; P = 0.034). The cut-off value for the prediction of postnatal CoA was 35.5 weeks of gestation, with a sensitivity and specificity of 77.8 and 69.2%, respectively. CONCLUSION: AoI-R determined by color Doppler echocardiography can become a useful tool in the screening of fetal CoA, especially at < 35 weeks of gestation. PMID- 29170886 TI - Phase II study of doxorubicin and thalidomide in patients with refractory aggressive fibromatosis. AB - Background To evaluate the efficacy and safety of doxorubicin (ADM) combined with thalidomide (THA) as a first-line treatment for patients with refractory aggressive fibromatosis (AF). Patients and Methods Eligible patients were treated with ADM 30 mg/m2 on days 1-2 and THA 200 mg nightly on days 1-21 every 3 weeks for a maximum of six cycles. THA was then continued for a total of 1 year. The primary end point was response rate (RR). Results Fifteen patients were enrolled in the study. No patient had a complete response, but five patients had partial responses, resulting in a RR of 33%. Eight patients (53%) had stable disease and two patients (13%) had progressive disease, and the disease control rate was 87%. The median progression free survival (mPFS) was 20.6 months (95% confidence interval, 14.5-26.7 months). Patients with below normal baseline serum albumin levels had significantly inferior mPFS compared with those with normal baseline serum albumin (1.4 months versus 23.7 months, P = 0.045). Grade 3/4 toxicities included leukopenia (33%), neutropenia (60%), febrile neutropenia (7%), nausea (7%), and vomiting (6.6%). Conclusions ADM plus THA was well-tolerated and effective as a first-line treatment for patients with refractory AF. However, patients with hypoalbuminemia at baseline had inferior clinical outcomes, and further studies are needed to investigate this issue. PMID- 29170885 TI - The structure of the S-layer of Clostridium difficile. AB - The nosocomially acquired pathogen Clostridium difficile is the primary causative agent of antibiotic associated diarrhoea and causes tens of thousands of deaths globally each year. C. difficile presents a paracrystalline protein array on the surface of the cell known as an S-layer. S-layers have been demonstrated to possess a wide range of important functions, which, combined with their inherent accessibility, makes them a promising drug target. The unusually complex S-layer of C. difficile is primarily comprised of the high- and low- molecular weight S layer proteins, HMW SLP and LMW SLP, formed from the cleavage of the S-layer precursor protein, SlpA, but may also contain up to 28 SlpA paralogues. A model of how the S-layer functions as a whole is required if it is to be exploited in fighting the bacterium. Here, we provide a summary of what is known about the S layer of C. difficile and each of the paralogues and, considering some of the domains present, suggest potential roles for them. PMID- 29170888 TI - Booming cancer immunotherapy fighting tumors. PMID- 29170887 TI - Early and late outcomes after open ascending aortic surgery: 47-year experience in a single centre. AB - The aims of the study are to describe the long-term survival of patients undergoing primary open ascending aortic surgery and to portray the evolution of aortic surgery during six decades in a single centre. Included were all 614 patients who underwent primary ascending aortic surgery in 1968-2014 at one Nordic university hospital. Patients were identified and data were collected from patient records and surgical logs. Mortality data were acquired from the national registry. Median follow-up was 11.2 years using reverse Kaplan-Meier method. Overall 30-day survival was 91.2% and for 30-day survivor rates were 86.9, 77.6, 52.1, 38.3 and 26.7% at 5, 10, 20, 30 and 40 years. There was no significant difference in long-term survival for 30-day survivors (p = 0.105) between patients treated emergently for dissection/rupture and electively (mainly ascending aortic aneurysms). On Cox regression era of surgery (p = 0.006), increasing age (p < 0.001) and indication (p < 0.001) were predictors of 30-day mortality. Arch involvement indicated twofold risk (HR 2.09, p = 0.05) compared to non-arch involved. Only increasing age (p < 0.001) predicted long-term mortality. There was a sixfold risk of 30-day mortality in the earliest era compared to the latest (p = 0.03). After the early postoperative phase following ascending aortic surgery, the surgical indication and urgency of the index operation have no significant impact on long-term survival. The very long term survival after ascending aortic surgery is excellent for 30-day survivors and improved through the era. Surgical treatment has improved and perioperative mortality has decreased significantly in 47 years. PMID- 29170889 TI - Transfer RNA-derived small RNAs in plants. AB - Rather than random degradation products, the 18 to 40 nucleotides (nt) transfer RNA-derived small RNAs (tsRNAs) are RNA species generated specifically from pre RNAs or mature tRNAs in archaea, bacteria and eukaryotes. Recent studies from animal systems have shown that tsRNAs are important non-coding RNAs that regulate gene expression at the transcriptional and/or post-transcriptional levels. They are involved in various biological processes, such as cell proliferation, tumor genesis, stress response and intergenerational epigenetic inheritance. In this review, we will summarize the discovery, biogenesis, and function of tsRNAs in higher plants. In addition, analysis on tsRNAs from lower plants is shown. PMID- 29170890 TI - CART trials are going ahead. PMID- 29170891 TI - AMPK and cardiac remodelling. AB - Cardiac remodelling is generally accepted as a critical process in the progression of heart failure. Myocyte hypertrophy, inflammatory responses and cardiac fibrosis are the main pathological changes associated with cardiac remodelling. AMP-activated protein kinase (AMPK) is known as an energy sensor and a regulator of cardiac metabolism under normal and ischaemic conditions. Additionally, AMPK has been shown to play roles in cardiac remodelling extending well beyond metabolic regulation. In this review, we discuss the currently defined roles of AMPK in cardiac remodelling and summarize the effects of AMPK on cardiac hypertrophy, inflammatory responses and fibrosis and the molecular mechanisms underlying these effects. In addition, we discuss some pharmacological activators of AMPK that are promising treatments for cardiac remodelling. PMID- 29170892 TI - Advancement in regional immunity and its clinical implication. AB - Organs in our body have formed their own unique immune surveillance system that is finely tuned by in situ milieu. Sequestrated tissue-resident immune cells differ from their counterparts in circulation and participate in tissue physiological activities and the maintenance of local homeostasis. Dysregulation of regional immunity leads to organ-specific inflammatory injuries. Here we review the recent developments in the field of tissue-resident immune cells and organ-specific regional immunity, and discuss their clinical implication. PMID- 29170893 TI - Comparison of the gut microbiota composition between wild and captive sika deer (Cervus nippon hortulorum) from feces by high-throughput sequencing. AB - The gut microbiota is characterized as a complex ecosystem that has effects on health and diseases of host with the interactions of many other factors together. Sika deer is the national level for the protection of wild animals in China. The available sequencing data of gut microbiota from feces of wild sika deer, especially for Cervus nippon hortulorum in Northeast China, are limited. Here, we characterized the gastrointestinal bacterial communities of wild (7 samples) and captive (12 samples) sika deer from feces, and compared their gut microbiota by analyzing the V3-V4 region of 16S rRNA gene using high-throughput sequencing technology on the Illumina Hiseq platform. Firmicutes (77.624%), Bacteroidetes (18.288%) and Tenericutes (1.342%) were the most predominant phyla in wild sika deer. While in captive sika deer, Firmicutes (50.710%) was the dominant phylum, followed by Bacteroidetes (31.996%) and Proteobacteria (4.806%). A total of 9 major phyla, 22 families and 30 genera among gastrointestinal bacterial communities showed significant differences between wild and captive sika deer. The specific function and mechanism of Tenericutes in wild sika deer need further study. Our results indicated that captive sika deer in farm had higher fecal bacterial diversity than the wild. Abundance and quantity of diet source for sika deer played crucial role in shaping the composition and structure of gut microbiota. PMID- 29170894 TI - A novel dissociation between representational momentum and representational gravity through response modality. AB - When people are required to indicate the vanishing location of a moving object, systematic biases forward, in the direction of motion, and downward, in the direction of gravity, are usually found. Both these displacements, called representational momentum and representational gravity, respectively, are thought to reflect anticipatory internal mechanisms aiming to overcome neural delays in the perception of motion. We challenge this view. There may not be such a single mechanism. Although both representational momentum and representational gravity follow a specific time-course, compatible with an anticipation of the object's dynamics, they do not seem to be commensurable with each other, as they are differentially modulated by relevant variables, such as eye movements and strength of motion signals. We found separate response components, one related to overt motor localization behaviour and one limited to purely perceptual judgement. Representational momentum emerged only for the motor localization task, revealing a motor overshoot. In contrast, representational gravity was mostly evident for spatial perceptual judgements. We interpret the results in support of a partial dissociation in the mechanisms that give rise to representational momentum and representational gravity, with the former but not the latter strongly modulated by the enrolment of the motor system. PMID- 29170895 TI - Toward a Psychology of Resistance. AB - Resistance is all around us in contemporary life. It is an everyday phenomenon of personal and cultural life, as the Chaudhary et al. (2017) volume establishes with theoretical analyses and empirical examples from diverse cultural contexts. Resistance functions in the dynamics of person-by-culture encounters when one party takes an opposing position. With the purpose of working towards a unified approach to resistance, the authors in this volume lay down the foundations for a psychology of resistance as an everyday phenomenon. As a basis for analyzing the role of resistance in the dialectical processes of change, the volume presents resistance as: personal and social, oppositional, intentional and future oriented, transformational and developmental. We see different positions opening up a debate about whether resistance is a particular, intentional and oppositional phenomenon, or is the basic process of all dialectical transformational change. Further resistance to either position is consistent with moving forward in the development of a psychology of resistance. PMID- 29170896 TI - Modern Treatments of Haemophilia: Review of Cost-Effectiveness Analyses and Future Directions. AB - BACKGROUND: Cost is currently one of the most important aspects in haemophilia care. Factor concentrates absorb more than 90% of healthcare direct costs of haemophilia care, and the debate regarding the high cost of haemophilia treatments and their different use across different countries is increasing. OBJECTIVE: The objective of this study was to review cost-effectiveness analyses conducted on treatment options in haemophilia, focusing on their results and their strengths and limitations; to highlight the possible issues associated with economic evaluations of new treatment options. METHODS: Electronic searches in PubMed and EMBASE were performed to retrieve papers published between November 2015 and September 2017 to update the previous review of economic evaluations of haemophilia treatments by Drummond et al. Reference lists of included articles and reviews were examined for relevant studies, which were assessed for their quality and their empirical results. RESULTS: Twenty-six relevant economic analyses were identified; 15 (57.7%) were conducted in patients with haemophilia with inhibitors while 11 (42.3%) involved patients without inhibitors. There were methodological variations among the included studies, and differences in the treatment schemes make a comparative assessment of interventions for patients with haemophilia difficult. Only immune tolerance induction showed consistent results in its cost-saving profile compared with the treatment with bypassing agents. CONCLUSIONS: Economic evaluations of haemophilia treatments are increasing, but the identification of general cost-effectiveness trends is still difficult in these studies. We are now facing a new era in haemophilia management with a soaring need for high-quality economic evaluations, performed through proactive collaboration between clinical experts, budget holders and health economists. PMID- 29170897 TI - Selective tuning of activity in a multifunctional enzyme as revealed in the F21W mutant of dehaloperoxidase B from Amphitrite ornata. AB - Possessing both peroxidase and peroxygenase activities with a broad substrate profile that includes phenols, indoles, and pyrroles, the enzyme dehaloperoxidase (DHP) from Amphitrite ornata is a multifunctional catalytic hemoglobin that challenges many of the assumptions behind the well-established structure-function paradigm in hemoproteins. While previous studies have demonstrated that the F21W variant leads to attenuated peroxidase activity in DHP, here we have studied the impact of this mutation on peroxygenase activity to determine if it is possible to selectively tune DHP to favor one function over another. Biochemical assays with DHP B (F21W) revealed minimal decreases in peroxygenase activity of 1.2-2.1 fold as measured by 4-nitrophenol or 5-Br-indole substrate conversion, whereas the peroxidase activity catalytic efficiency for 2,4,6-trichlorophenol (TCP) was more than sevenfold decreased. Binding studies showed a 20-fold weaker affinity for 5-bromoindole (K d = 2960 +/- 940 MUM) in DHP B (F21W) compared to WT DHP B. Stopped-flow UV/visible studies and isotope labeling experiments together suggest that the F21W mutation neither significantly changes the nature of the catalytic intermediates, nor alters the mechanisms that have been established for peroxidase and peroxygenase activities in DHP. The X-ray crystal structure (1.96 A; PDB 5VLX) of DHP B (F21W) revealed that the tryptophan blocks one of the two identified TCP binding sites, specifically TCPinterior, suggesting that the other site, TCPexterior, remains viable for binding peroxygenase substrates. Taken together, these studies demonstrate that blocking the TCPinterior binding site in DHP selectively favors peroxygenase activity at the expense of its peroxidase activity. PMID- 29170899 TI - Preoperative urine culture is unnecessary in asymptomatic men prior to prostate needle biopsy. AB - PURPOSE: To determine the clinical utility of preoperative urine cultures in asymptomatic men undergoing prostate needle biopsy (PNB). METHODS: One hundred fifty asymptomatic men had urine cultures obtained 14-days prior to PNB. As per study protocol, positive cultures were not treated. Antibiotic prophylaxis prior to PNB included ciprofloxacin 500 mg the night before and morning of the biopsy. Repeat urine cultures were obtained immediately prior to PNB with colony-forming units (CFUs) annotated. Infectious complications post-biopsy were recorded. RESULTS: Of the 150 men, six patients (4%) had evidence of asymptomatic bacteriuria with > 10,000 CFU/mL on office urine culture. Repeat urine cultures on morning of biopsy in all 150 patients noted a mean bacterial count of 55 CFU/mL (range 0-1000). All six patients with positive office urine cultures had < 100 CFU/mL at time of PNB. Following biopsy, four patients (2.7%) developed an infectious complication including two with sepsis and two with culture-positive UTIs. The causative organism in all cases was quinolone-resistant E. coli. None of the six patients with preoperative positive urine cultures developed an infectious complication following PNB. CONCLUSIONS: In this prospective observational study, under 5% of asymptomatic men had positive office cultures prior to PNB. Furthermore, repeat urine culture on the morning of biopsy showed resolution in these patients, and none developed post-biopsy infectious complications. Routine office urine culture in the asymptomatic male prior to PNB was unnecessary. PMID- 29170898 TI - Reconsideration of frailty in relation to surgical indication. AB - Given that an increasing number of elderly patients are undergoing surgical procedures for a diversity of indications, the concept of frailty is currently being examined in more depth in clinical medicine. Established surgical risk scores designed to predict mortality are mainly focused on general demographic information and clinical factors; however, these do not account for the frailty condition. With vulnerability and low resiliency in the frail elderly, these conventional scores are unable to accurately predict postoperative outcomes including adverse complications, disability, the need for additional rehabilitation, and prolonged length of hospitalization. Over the last decade, it has been demonstrated that frailty is an independent risk factor of surgery and strongly associated with adverse postoperative outcomes and mortality. It is essential today that surgeons assimilate the concept of frailty and the relationship between frailty and surgical outcomes. A preoperative frailty assessment can assist in determining surgical indication and optimal perioperative management, ultimately impacting the postoperative functional state and quality of life. Here we review the validity of preoperative frailty assessments for surgical intervention, possible treatments for frailty, and indicate future directions in this field. PMID- 29170900 TI - The challenges of closing an ileostomy in patients with total intestinal aganglionosis after small bowel transplant. AB - We present the case of a 14-year-old male with a history of small bowel transplantation for long segment Hirschsprung's disease who underwent Duhamel ileorectal pull-through procedure. In post-transplant, the patient had no restrictions and was not TPN-dependent. To improve his quality of life, he and his family were interested in closing the ileostomy and undergoing pull-through surgery. The complexity of the case includes the presence of an aganglionic rectal segment-a short root of the mesentery due to the small bowel transplant and significant immunosuppression. At the moment, he is continent, doing well, and has not had any remarkable complications. PMID- 29170901 TI - Randomized, blinded, controlled trial on effectiveness of photobiomodulation therapy and exercise training in the fibromyalgia treatment. AB - This study evaluated the role of the phototherapy and exercise training (EXT) as well as the combined treatment in general symptoms, pain, and quality of life in women suffering from fibromyalgia (FM). A total of 160 women were enrolled and measures were carried out in two sets: it was sought to identify the acute effect for a single phototherapy and EXT session (Set 1); long-term effect (10 weeks) of the interventions (Set 2). Phototherapy irradiation was performed at 11 locations in their bodies, employing a cluster with nine diodes (one super-pulsed infrared 905 nm, four light-emitting diodes [LEDs] of 640 nm, and four LEDs of 875 nm, 39.3 J per location). Algometry and VAS instrument were applied to evaluate pain. The FM symptoms were evaluated with Fibromyalgia Impact Questionnaire (FIQ) and Research Diagnostic Criteria (RDC) instruments. Quality of life was assessed through SF-36 survey. Set 1: pain threshold was improved with the phototherapy, and EXT improved the pain threshold for temporomandibular joint (right and left body side) and occipital site (right body side). Set 2: there was improved pain threshold in several tender points with the phototherapy and EXT. There was an overlap of therapies to reduce the tender point numbers, anxiety, depression, fatigue, sleep, and difficulty sleeping on FIQ/RDC scores. Moreover, quality of life was improved with both therapies. The phototherapy and EXT improved the pain threshold in FM women. A more substantial effect was noticed for the combined therapy, in which pain relief was accomplished by improving VAS and FIQ scores as well as quality of life.

Experiences Among Survivors and Parents of Children with Retinoblastoma in Kenya. AB - Genetic testing and counseling have become integral to the timely control of heritable cancers, like the childhood eye cancer retinoblastoma. This study aimed to determine attitudes, knowledge and experiences related to retinoblastoma genetics, among survivors and parents of children with retinoblastoma in Kenya. This qualitative study used focus groups as the primary data collection method, coupled with a brief demographic questionnaire. Study settings were Kenyatta National Hospital and Presbyterian Church of East Africa Kikuyu Hospital. Thematic analysis was used to identify key themes. Thirty-one individuals participated in five focus groups. Two main concepts emerged: (1) the origins of retinoblastoma are unclear, and (2) retinoblastoma is associated with significant challenges. The lack of clarity surrounding the origins of retinoblastoma was linked to limited knowledge of retinoblastoma genetics, and limited genetic counseling delivery and uptake. The challenges associated with retinoblastoma were discussed in terms of the impact of the diagnosis on individuals and families, and unmet healthcare needs related to the diagnosis. Next steps will incorporate these findings to develop evidence-informed and accessible cancer genetic services in Kenya. PMID- 29170904 TI - Effects of chronic endurance exercise training on serum 25(OH)D concentrations in elderly Japanese men. AB - BACKGROUND: Higher levels of physical activity and cardiorespiratory fitness are positively related to serum 25-hydroxyvitamin D [25(OH)D] concentrations; however, the response of 25(OH)D concentrations to chronic endurance exercise training is unclear. Therefore, the purpose of this study was to elucidate whether serum 25(OH)D concentrations were directly increased by 5 weeks of endurance exercise training and influenced by changes in body fat in elderly men. METHODS: Twenty elderly Japanese men were randomized to either the 5-week endurance exercise training group (ET group; N = 10) or the sedentary control group (SC group; N = 10). Fasting blood samples were collected to determine serum 25(OH)D and other blood parameters. The visceral fat area and hepatic fat content were assessed by magnetic resonance imaging and proton magnetic resonance spectroscopy, respectively. RESULTS: After 5 weeks of endurance exercise training, the levels of maximal oxygen uptake (VO2 max) were significantly increased from 23.3 at baseline to 28.1 mL/kg/min at the endpoint for the ET group; levels were unchanged for the SC group. A significant seasonal reduction in serum 25(OH)D concentrations was observed in the SC group (P < 0.05), while no change was found in the ET group. The results may be partly attributed to the slight decrease in intrahepatic fat in the ET group. No changes were observed in percent body fat or visceral fat area. CONCLUSIONS: The results of our study suggest that 5 weeks of endurance training could inhibit the seasonal reduction in serum 25(OH)D concentrations without changes in body fat. PMID- 29170906 TI - Bevacizumab and risk of intracranial hemorrhage in patients with brain metastases: a meta-analysis. AB - Administration of bevacizumab to patients with brain metastases (BM) is controversial due to concerns about the increased risk of intracranial hemorrhage (ICH). This meta-analysis assessed whether the risk of ICH increases in BM patients receiving treatments that contain bevacizumab versus without. PubMed, Embase, Cochrane Library and annual meeting abstracts of the American Society of Clinical Oncology up to 13 November 2016 were searched for studies that referred to ICH complications due to bevacizumab in patients with BM. Eight studies involving 8713 patients were included in this analysis. Compared with the control arm without bevacizumab, the bevacizumab treatment arm did not exhibit a significant increase in ICH [odds ratio (OR) 1.20; 95% confidence intervals (CI) 0.69-2.09; P = 0.53]. Subgroup analyses with retrospective studies showed a similar result, although subgroup analyses with prospective studies failed. This meta-analysis revealed that bevacizumab does not significantly increase the risk of ICH in solid tumor patients with BM. PMID- 29170905 TI - Irisin in metabolic diseases. AB - INTRODUCTION: Irisin is a myokine/adipokine induced by the exercise in mice and humans, which is proposed to induce "browning" of white adipose tissue, its primary target, thus increasing thermogenesis and energy expenditure. Since its identification, irisin has been linked to favorable effects on metabolic diseases, including obesity, type 2 diabetes mellitus (T2DM), lipid metabolism and cardiovascular disease (CVD), nonalcoholic fatty liver disease (NAFLD), polycystic ovary syndrome (PCOS), and metabolic bone diseases. Generally, despite the promising profile of irisin in rodents, its effects on human are less recognized. REVIEW: Most, but not all studies show a positive association between irisin and indices of adiposity. In T2DM, NAFLD, and CVD, most observational studies reported lower irisin levels in patients than controls. Regarding metabolic bone diseases, irisin is positively associated with bone mineral density and strength in athletes, and inversely associated with osteoporotic fractures in postmenopausal osteoporosis. In PCOS, data remain largely conflicting. Irisin does not seem to be further reduced when two metabolic diseases, e.g., T2DM and NAFLD, or obesity and NAFLD exist though more data are needed. Furthermore, it seems that diverse confounders may have affected the results of different clinical studies. CONCLUSION: Irisin remains an appealing molecule from a pathophysiological point of view and an appealing therapeutic target for metabolic diseases, albeit much research is still needed. PMID- 29170907 TI - An immune-related lncRNA signature for patients with anaplastic gliomas. AB - We investigated immune-related long non-coding RNAs (lncRNAs) that may be exploited as potential therapeutic targets in anaplastic gliomas. We obtained 572 lncRNAs and 317 immune genes from the Chinese Glioma Genome Atlas microarray and constructed immune-related lncRNAs co-expression networks to identify immune related lncRNAs. Two additional datasets (GSE16011, REMBRANDT) were used for validation. Gene set enrichment analysis and principal component analysis were used for functional annotation. Immune-lncRNAs co-expression networks were constructed. Nine immune-related lncRNAs (SNHG8, PGM5-AS1, ST20-AS1, LINC00937, AGAP2-AS1, MIR155HG, TUG1, MAPKAPK5-AS1, and HCG18) signature was identified in patients with anaplastic gliomas. Patients in the low-risk group showed longer overall survival (OS) and progression-free survival than those in the high-risk group (P < 0.0001; P < 0.0001). Additionally, patients in the high-risk group displayed no-deletion of chromosomal arms 1p and/or 19q, isocitrate dehydrogenase wild-type, classical and mesenchymal TCGA subtype, G3 CGGA subtype, and lower Karnofsky performance score (KPS). Moreover, the signature was an independent factor and was significantly associated with the OS (P = 0.000, hazard ratio (HR) = 1.434). These findings were further validated in two additional datasets (GSE16011, REMBRANDT). Low-risk and high-risk groups displayed different immune status based on principal components analysis. Our results showed that the nine immune-related lncRNAs signature has prognostic value for anaplastic gliomas. PMID- 29170908 TI - Local control and overall survival for adjuvant stereotactic radiosurgery in patients with residual or recurrent disease. AB - Prior studies of post-operative stereotactic radiosurgery (SRS) have not distinguished between Adjuvant SRS (ARS) versus Adjuvant SRS to residual/recurrent disease (ARD). In this study, we defined ARS and ARD and investigated local control (LC), overall survival (OS), distant development of brain metastases (DBF), and leptomeningeal disease (LMD). We retrospectively identified BM patients who received surgical resection and SRS for BM from an IRB approved database between Jan 2009-Aug 2015. Patients were stratified into two groups: ARS and ARD. LC was determined by follow-up MRI studies and OS was measured from the date of surgery. LC and OS were assessed using the Kaplan-Meier method. 70 cavities underwent surgical resection of BM and received SRS to the post-operative bed. 41 cavities were classified as ARS and 29 as ARD. There was no significant difference in 12-month LC between the ARS and ARD group (71.4 vs. 80.8%, respectively; p = 0.135) from the time point of SRS. The overall 1-year survival for ARS and ARD was 79.9 and 86.1%, respectively (p = 0.339). Mean time to progression was 6.45 and 8.0 months and median follow-up was 10 and 15 months for ARS and ARD, respectively. 11.8% of ARS patients and 15.4% of ARD patients developed LMD, p = 0.72. 29.4% of ARS and 48.0% of ARD patients developed DBF, p = 0.145. Our findings suggest that observation after surgical resection, with subsequent treatment with SRS after the development of local failure, may not compromise treatment efficacy. If validated, this would spare patients who do not recur post-surgically from additional treatment. PMID- 29170909 TI - New therapeutic approaches for brainstem tumors: a comparison of delivery routes using nanoliposomal irinotecan in an animal model. AB - Despite the advances in imaging, surgery and radiotherapy, the majority of patients with brainstem gliomas die within 2 years after initial diagnosis. Factors that contribute to the dismal prognosis of these patients include the infiltrative nature and anatomic location in an eloquent area of the brain, which prevents total surgical resection and the presence of the blood-brain barrier (BBB), which reduces the distribution of systemically administered agents. The development of new therapeutic approaches which can circumvent the BBB is a potential path to improve outcomes for these children. Convection-enhanced delivery (CED) and intranasal delivery (IND) are strategies that permit direct drug delivery into the central nervous system and are an alternative to intravenous injection (IV). We treated rats bearing human brainstem tumor xenografts with nanoliposomal irinotecan (CPT-11) using CED, IND, and IV. A single treatment of CED irinotecan had a similar effect on overall survival as multiple treatments by IV route. IND CPT-11 showed significantly increased survival of animals with brainstem tumors, and demonstrated the promise of this non-invasive approach of drug delivery bypassing the BBB when combined with nanoliposomal chemotherapy. Our results indicated that using CED and IND of nanoliposomal therapy increase likelihood of practical therapeutic approach for the treatment of brainstem gliomas. PMID- 29170910 TI - Bioenergetic reprogramming plasticity under nitrogen depletion by the unicellular green alga Scenedesmus obliquus. AB - MAIN CONCLUSION: Simultaneous nitrogen depletion and 3,4-dichlorophenol addition induce a bioenergetic microalgal reprogramming, through strong Cyt b 6 f synthesis, that quench excess electrons from dichlorophenol's biodegradation to an overactivated photosynthetic electron flow and H 2 -productivity. Cellular energy management includes "rational" planning and operation of energy production and energy consumption units. Microalgae seem to have the ability to calculate their energy reserves and select the most profitable bioenergetic pathways. Under oxygenic mixotrophic conditions, microalgae invest the exogenously supplied carbon source (glucose) to biomass increase. If 3,4-dichlorophenol is added in the culture medium, then glucose is invested more to biodegradation rather than to growth. The biodegradation yield is enhanced in nitrogen-depleted conditions, because of an increase in the starch accumulation and a delay in the establishment of oxygen-depleted conditions in a closed system. In nitrogen depleted conditions, starch cannot be invested in PSII-dependent and PSII independent pathways for H2-production, mainly because of a strong decrease of the cytochrome b 6 f complex of the photosynthetic electron flow. For this reason, it seems more profitable for the microalga under these conditions to direct the metabolism to the synthesis of lipids as cellular energy reserves. Nitrogen-depleted conditions with exogenously supplied 3,4-dichlorophenol induce reprogramming of the microalgal bioenergetic strategy. Cytochrome b 6 f is strongly synthesized (mainly through catabolism of polyamines) to manage the electron bypass from the dichlorophenol biodegradation procedure to the photosynthetic electron flow (at the level of PQ pool) and consequently through cytochrome b 6 f and PSI to hydrogenase and H2-production. All the above showed that the selection of the appropriate cultivation conditions is the key for the manipulation of microalgal bioenergetic strategy that leads to different metabolic products and paves the way for a future microalgal "smart" biotechnology. PMID- 29170911 TI - Characterization of an acetohydroxy acid synthase mutant conferring tolerance to imidazolinone herbicides in rice (Oryza sativa). AB - MAIN CONCLUSION: The acetohydroxy acid synthase S627N mutation confers herbicide tolerance in rice, and the rice variety containing this mutation produces good yields. This variety is commercially viable at Shanghai and Jiangsu regions in China. Weedy rice is a type of rice that produces lower yields and poorer quality grains than cultivated rice. It plagues commercial rice fields in many countries. One strategy to control its proliferation is to develop rice varieties that are tolerant to specific herbicides. Acetohydroxy acid synthase (AHAS) mutations have been found to confer herbicide tolerance to rice. Here, we identified a single mutation (S627N) in AHAS from an indica rice variety that conferred tolerance against imidazolinone herbicides, including imazethapyr and imazamox. A japonica rice variety (JD164) was developed to obtain herbicide tolerance by introducing the mutated indica ahas gene. Imidazolinone application was sufficient to efficiently control weedy rice in the JD164 field. Although the imazethapyr treatment caused dwarfing in the JD164 plants, it did not significantly reduce yields. To determine whether the decrease of the ahas mRNA expression caused the dwarfism of JD164 after imazethapyr application, we detected the ahas mRNA level in plants. The abundance of the ahas mRNA in JD164 increased after imidazolinone application, thus excluding the mRNA expression level as a possible cause of dwarfism. Activity assays showed that the mutated AHAS was tolerant to imidazolinone but the catalytic efficiency of the mutated AHAS decreased in its presence. Moreover, the activity of the mutated AHAS decreased more in the presence of imazethapyr than in the presence of imazamox. We observed no difference in the AHAS secondary structures, but homology modeling suggested that the S627N mutation enabled the substrate to access the active site channel in AHAS, resulting in imidazolinone tolerance. Our work combined herbicides with a rice variety to control weedy rice and showed the mechanism of herbicide tolerance in this rice variety. PMID- 29170912 TI - Relationships between water status and photosystem functionality in a chlorolichen and its isolated photobiont. AB - MAIN CONCLUSION: Drought tolerance was greater in the whole lichen than in its isolated photobiont. Cell turgor state has an influence on the functionality of photosynthetic process in lichens. Irreversible thermodynamics is widely used to describe the water relations of vascular plants. However, poikilohydrous organisms like lichens and aeroterrestrial microalgae have seldom been studied using this approach. Water relations of lichens are generally addressed without separate analysis of the mycobiont and photobiont, and only few studies have correlated changes in photosynthetic efficiency of dehydrating lichens to accurate measurements of their water potential components. We measured water potential isotherms and chlorophyll a fluorescence in the lichen Flavoparmelia caperata harvested in different seasons, as well as in its isolated photobiont, the green alga Trebouxia gelatinosa, either exposed to water stress cycles or fully hydrated. No significant seasonal trends were observed in lichen water relations parameters. Turgor loss point and osmotic potential of the whole thallus were significantly lower than those measured in the photobiont, while differences between the water stressed photobiont and controls were not significant. Dehydration-induced drop of F v/F m was correlated with turgor loss, revealing that the photosynthetic activity of lichens partly depends on their turgor level. We provided one of the first quantitative evidences of the influence that turgor status could exert on the functionality of photosynthetic processes in lichens. PMID- 29170913 TI - Impact of HBV replication in peripheral blood mononuclear cell on HBV intrauterine transmission. AB - This study determined the effect of hepatitis B virus (HBV) replication in peripheral blood mononuclear cell (PBMC) from HBsAg-positive mothers on HBV intrauterine transmission. A total of 150 HBsAg-positive mothers and their neonates were recruited in this study. Within 24 h after birth, HBV serological markers, serum HBV DNA, PBMC HBV relaxed circular DNA (rcDNA), and covalently closed circular DNA (cccDNA) were measured in the HBsAg-positive mothers and their neonates before passive-active immune prophylaxis. The relationship between HBV replication in PBMC and HBV intrauterine transmission was examined through Chisquare test and logistic regression. The rate of HBV intrauterine transmission was 8.00% (12/150) in the 150 neonates born to HBsAg-positive mothers. The positivities of PBMC HBV rcDNA and cccDNA in the HBsAg-positive mothers were 36.67% (55/150) and 10% (15/150), respectively. Maternal PBMC HBV cccDNA was a risk factor of HBV intrauterine transmission (OR = 6.003, 95% CI: 1.249-28.855). Maternal serum HBeAg was a risk factor of PBMC HBV rcDNA (OR = 3.896, 95% CI: 1.929-7.876) and PBMC HBV cccDNA (OR = 3.74, 95% CI: 1.186-11.793) in the HBsAg positive mothers. Administration of hepatitis B immune globulin was a protective factor of PBMC HBV cccDNA (OR = 0.312, 95%CI: 0.102-0.954) during pregnancy. The positivity of PBMC HBV rcDNA was related to that of cccDNA in the HBsAg-positive mothers (chi 2= 5.087, P = 0.024). This study suggests that PBMC is a reservoir of HBV and an extrahepatic site for virus replication and plays a critical role in HBV intrauterine transmission.

AB - Superinfection is frequently detected among individuals infected by human immunodeficiency virus type I (HIV-1). Superinfection occurs at similar frequencies at acute and chronic infection stages but less frequently than primary infection. This observation indicates that the immune responses elicited by natural HIV-1 infection may play a role in curb of superinfection; however, these responses are not sufficiently strong to completely prevent superinfection. Thus, a successful HIV-1 vaccine likely needs to induce more potent and broader immune responses than those elicited by primary infection. On the other hand, potent and broad neutralization responses are more often detected after superinfection than during monoinfection. This suggests that broadly neutralizing antibodies are more likely induced by sequential immunization of multiple different immunogens than with only one form of envelope glycoprotein immunogens. Understanding why the protection from superinfection by immunity induced by primary infection is insufficient and if superinfection can lead to cross reactive immune responses will be highly informative for HIV-1 vaccine design. PMID- 29170915 TI - Potential use of serum HBV RNA in antiviral therapy for chronic hepatitis B in the era of nucleos(t)ide analogs. AB - Although the efficacy of nucleos(t)ide analogue (NA) has been confirmed for treatment of chronic hepatitis B, long-term therapy has been recommended due to the high frequency of off-therapy viral DNA rebound and disease relapse. In this review, the RNA virion-like particles of hepatitis B virus (HBV) are integrated into the life cycle of HBV replication, and the potential significance of serum HBV RNA is systematically described. The production of HBV RNA virion-like particles should not be blocked by NA; in this regard, serum HBV RNA is found to be a suitable surrogate marker for the activity of intrahepatic covalently closed circular DNA (cccDNA), particularly among patients receiving NA therapy. Therefore, the concept of virological response is redefined as persistent loss of serum HBV DNA and HBV RNA. In contrast to hepatitis B surface antigen (HBsAg) that can originate from either the cccDNA or the integrated HBV DNA fragment, serum HBV RNA, with pregenomic RNA origination, can only be transcribed from cccDNA. Therefore, the loss of serum HBV RNA would likely be a promising predicator for safe drug discontinuation. The clinical status of consistent loss of serum HBV RNA accompanied with low serum HBsAg levels might be implicated as a "para-functional cure," a status nearly close to the functional cure of chronic hepatitis B, to distinguish the "functional cure" characterized as serum HBsAg loss with or without anti-HBs seroconversion. PMID- 29170916 TI - Development of small-molecule viral inhibitors targeting various stages of the life cycle of emerging and re-emerging viruses. AB - In recent years, unexpected outbreaks of infectious diseases caused by emerging and re-emerging viruses have become more frequent, which is possibly due to environmental changes. These outbreaks result in the loss of life and economic hardship. Vaccines and therapeutics should be developed for the prevention and treatment of infectious diseases. In this review, we summarize and discuss the latest progress in the development of small-molecule viral inhibitors against highly pathogenic coronaviruses, including severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus, Ebola virus, and Zika virus. These viruses can interfere with the specific steps of viral life cycle by blocking the binding between virus and host cells, disrupting viral endocytosis, disturbing membrane fusion, and interrupting viral RNA replication and translation, thereby demonstrating potent therapeutic effect against various emerging and re-emerging viruses. We also discuss some general strategies for developing small-molecule viral inhibitors. PMID- 29170917 TI - Radical versus conservative surgical treatment of liver hydatid cysts: a meta analysis. AB - To date, the efficacy of radical surgery (RS) versus conservative surgery (CS) for liver hydatid cysts (LHC) remains controversial. This meta-analysis was conducted to compare the two interventions. PubMed, Embase, and Web of Science were searched from their inceptions until June 2016. Meta-analysis was performed using STATA 12.0 software. We identified 19 eligible studies from 10 countries by retrieval. In total, 1853 LHC patients who received RS were compared with 2274 patients treated by CS. The risk of postoperative overall complication, biliary fistula, and recurrence was significantly lower, and operation time was significantly longer in the RS group. However, no statistically significant differences were found in terms of mortality risk and the duration of hospital stay between RS and CS. No significant publication biases were observed in all the above analyses. In conclusion, RS reduces the rates of postoperative complications and recurrence, whereas no trend toward such a reduction in mortality was observed in LHC patients. PMID- 29170918 TI - Determining "abnormal" levator hiatus distensibility using three-dimensional transperineal ultrasound in Chinese women. AB - The dimension of the levator hiatus is a possible predictor of pelvic organ prolapse (POP). This retrospective study investigated 360 women who went to urogynecological clinic for pelvic floor discomfort. Levator hiatus dimensions were obtained by three-dimensional transperineal ultrasound and results were compared between women with and without significantly objective prolapse (International Continence Society POP quantification, grade 2 or higher). Receiver operating characteristic (ROC) curve analyses were performed to determine valid screening index for detecting abnormal levator hiatus distensibility. Women with significantly objective prolapse had significantly higher levator hiatus dimensions than those without (all P < 0.001). ROC curve analyses confirmed that hiatal area (HA) of 19.5 cm2 during Valsalva maneuver can be used as single-screening index for abnormal levator hiatus distensibility with sensitivity of 0.80 and specificity of 0.70. In this study, we used a two-step method and achieved higher sensibility (0.80 vs. 0.87) without reducing specificity (0.70 vs. 0.71) compared with a single-screening index method. As a result, we suggest that HA ? 19.5 cm2 during Valsalva maneuver is an indicator of abnormal levator hiatus distensibility in Chinese women and that the two-step method has higher sensitivity in detecting abnormal distensibility.

PMID- 29170919 TI - Current advances in the elimination of hepatitis B in China by 2030. AB - With its 78 million chronic carriers, hepatitis B virus (HBV) infection is still one of the leading public health challenges in China. Over the last two decades, China has made great progress on the prevention of HBV transmission through national vaccination programs. Zero transmission from mother to infant has been proposed as the current goal. Available anti-HBV therapy is efficacious in suppressing HBV replication; however, it fails to completely cure patients with chronic hepatitis B and even requires lifelong treatment. To reduce the costs and improve the efficacy, several trials have been recently conducted in China to optimize the current anti-HBV managements. Novel biomarkers were identified to predict treatment outcomes, and new promising treatment strategies were developed. Reports also indicate that coinfections of HBV with other hepatotropic viruses and human immunodeficiency virus are common in China and cause severe liver diseases, which should be recognized early and treated properly. Work is still needed to eliminate hepatitis B in China by 2030. PMID- 29170922 TI - Vaccine Safety and Surveillance for Adverse Events Following Immunization (AEFI) in India. AB - RATIONALE: Assured quality vaccines and safe immunization practices are pre requisite to successful immunization programs. All vaccines go through stringent safety checks during pre-licensure stage. Adverse Events Following Immunization (AEFI) Surveillance program is an integral part of routine immunization program in India to monitor the vaccine safety in the post licensure phase. Indian AEFI Program: National AEFI surveillance relies on passive surveillance and reporting by the health functionaries and practitioners. Vigorous strengthening of AEFI surveillance has resulted in manifold rise in absolute number of AEFI reports across several reporting units in the country in the last decade. Establishment of National AEFI Secretariat, National Technical Collaborating Centre, and development of risk communication strategy as well as quality management certification are some of the unique aspects of this public health program. All serious AEFI reports undergo a systematic causality assessment as per WHO algorithm by trained committees. National AEFI surveillance system has forged formal linkages with national pharmacovigilance program, the regulators, and professional bodies. Challenges: The number of the reported serious AEFIs are still far less than the expected numbers. Although the AEFI committees at the district and state levels have been established, a large proportion are far from functional. Way forward: As the national immunization program introduces newer vaccines for different age groups and coverage improves, the issues of vaccine hesitancy and confidence are likely to be raised more often and the AEFI surveillance program will have to assume greater responsibility to comprehensively respond to the community concerns and sustain public confidence in vaccines.

AB - OBJECTIVE: Urinary screening is a simple inexpensive tool to evaluate kidney functions. The authors carried out urinary screening of school children for early detection of kidney diseases. METHODS: Children in the age group 5-15 y were screened for urinalysis. They were divided in 2 groups; group-1 included 5-10 y and group-2 included >10-15 y old children. RESULTS: Urine samples of 3340(78%) out of 4283 enrolled children were tested. Abnormal samples were found in 5.75%; with proteinuria in 4.59%, pyuria in 3.29% and hematuria in 4.31%. Males constituted 47.71% in group-1 and 54.64% in group-2. Low body mass index was found in 94.1% group-1 and 78.99% group-2 children. Mild proteinuria was found in 1.2% group-1 and 2.56% group-2 children. Severe proteinuria was more in group-2 (0.77% vs. 0.06%) with female preponderance. Glucosuria was found in 1 boy of group-2. Urobilinogen was more in group-2 (0.65% vs. 0.24%) with male preponderance. Nitrituria was found in 9 girls. Pyuria (2.02% vs. 1.27%) and hematuria were more in group-2 (3.04% vs. 1.87%) with female preponderance. Combined proteinuria and hematuria (0.42% vs. 0.24%) as well bacteruria and fungaluria were more in group-2 (4.11% vs. 1.39%). Six of 192 children with abnormal urinary findings were treated; 1 for urinary calculus and 5 for urinary tract infection. CONCLUSIONS: Abnormal urinary findings were more common in children >10 y of age. Thus urinary screening program of children can become useful for early detection of kidney diseases and contribute towards building up of a healthy nation.

AB - Waste from the beneficiation of fish was composted with crushed grass aiming to characterize their chemical composition and investigate the possibility of the use of the final compost as source of humic acids (HA) able to stimulate the growth of lettuce. Compost presented pH value, C/N ratio, and electrical conductivity that allow its use as an organic fertilizer. The element content was present in the following order of abundance in the compost: P > Ca > N > Mg > K > Fe > Zn > Mn > Mo > Cu, and the humus composition was similar to that observed in others kind of organic residues composted. The high content of oxygen pointed out a high level of oxidation of HA, in line with the predominance of phenolic acidity in the functional groups. The 13C-NMR spectra showed marked resonances due to the presence of lipids and other materials resistant to degradation as methoxy substituent and N-alkyl groups. A concentration of 20 mg L-1 HA increased significantly both dry and wet root matter in lettuce but the CO2 assimilation, stomatal conductance, and number of lateral roots of the plants were not affected. However, increases of 64% in the water-use efficiency was observed due to the HA addition, probably related to the root morphology alteration which resulted in 1.6-fold increase of lateral root average length and due to the higher H+ extrusion activity. Reuse of residues from the fish beneficiation activity by composting may represent a safe tool to increase the value of recycled organic residues and generate HA with potential use as plant growth stimulants. PMID- 29170927 TI - Climate mitigation, low-carbon society, and dynamism of educational institutes in a low-income country. AB - This paper aims to investigate carbon footprints of faculty members of University of Agriculture Faisalabad (UAF) associated with income and education in pursuance of a low-carbon society. For the study, 140 UAF faculty members (professors, associate professors, assistant professors, and lecturers) were selected using stratified random sampling technique, and a representative questionnaire was used to record primary data. Moreover, the ordinary least square (OLS) method was used to explain the statistical relationship between income, education, and carbon footprints. It was found that carbon footprints of UAF faculty members were 10.06 metric tons (mt) per year per person on an average. Our results further indicated that carbon footprints of assistant professors, associate professors, and professors were 10.83, 11.95, and 10.96 mt per person per annum, respectively. OLS estimates showed that an increase in one Doctor of Philosophy (Ph.D.) faculty member increases the carbon footprint by 1.15 mt per annum. Male faculty members emit more carbon footprints than females. Faculty members of Tenure Track System (TTS) had a higher income than those of Basic Pay Scale (BPS). Therefore, emissions of TTS faculty members were higher. Hence, in order to reduce carbon footprints and corroborate UAF campus environment-friendly, the attitude towards this aspect should be changed and awareness should be created. Furthermore, reduced car usage can be another bottom-up policy suggestion. As witnessed in green campuses of international universities, UAF should also be a motor-free campus (cycling and pedestrian only). PMID- 29170926 TI - Chemometric and high-resolution mass spectrometry tools for the characterization and comparison of raw and treated wastewater samples of a pilot plant on the SIPIBEL site. AB - Due to its key role in the contamination of natural resources, the assessment of raw and treated wastewater effluents is a current major concern and urges comprehensive analytical methods capable of selectively capturing the chemodiversity of these samples. In this context, the overall objective of this work can be summarized as (i) the assessment of the performance of secondary and tertiary (advanced oxidation) wastewater treatments through multivariate analysis followed by (ii) the comprehensive characterization of wastewater samples based on their spectral fingerprints and a combination of suspect and non-target screening approaches. Several compounds, belonging to different sources of contamination were annotated and/or partially identified: pharmaceuticals, metabolites and transformation compounds, human activity markers, surfactants, and polyethoxy compounds. These results highlight the contribution of filtering and screening tools such as monoisotopic exact mass, mass defect, MS/MS data dependent acquisitions, isotopic pattern and retention time to the selection, and the identification of environmental contaminants and their metabolites/degradation products. This paper completes the target study conducted in the SIPIBEL site and offers an alternative for the assessment of treatment processes by broadening the spectrum to a larger number of compounds and the correlations between them. PMID- 29170929 TI - The Validity of Bioelectrical Impedance Analysis to Measure Body Composition in Phenylketonuria. AB - AIM: To compare the measurement of total body water (TBW) and fat-free mass (FFM) using the criterion method of deuterium dilution space (2H2O) with bioelectrical impedance analysis (BIA) using a portable QuadScan 4000, Bodystat(r) in children and adolescents with phenylketonuria (PKU). METHODS: Sixteen patients with PKU, median age is 12.5 (range 5-20.6) years, were recruited into this cross-sectional study. TBW was measured by both deuterium dilution and BIA on the same occasion as per a standard protocol. FFM was estimated from predictive equations. RESULTS: There was no significant difference between TBWDeut and TBWBIA (p = 0.344) or FFMDeut and FFMBIA (p = 0.111). TBWDeut and TBWBIA were highly correlated (r = 0.990, p < 0.0001), as were FFMDeut and FFMBIA (r = 0.984, p < 0.0001). Bland Altman plots demonstrated that there was no proportional bias between the criterion method, TBWDeut, and the test method TBWBIA, in estimating TBW (beta = 0.056, adjusted r 2 = 0.069, p = 0.169) or FFM (beta = -0.089, adjusted r 2 = 0.142, p = 0.083). CONCLUSION: Our results suggest that when compared with the criterion method, the QuadScan 4000, Bodystat(r) can reliably be used to predict TBW and FFM in patients with PKU. We suggest that due to the portability and non invasive approach, this method can reliably be used to monitor body composition in the outpatient clinic setting, to further improve the monitoring and assessment of nutritional status in PKU. PMID- 29170928 TI - Leishmania mexicana differentiation involves a selective plasma membrane autophagic-like process. AB - Parasites of the Leishmania genus, which are the causative agents of leishmaniasis, display a complex life cycle, from a flagellated form (promastigotes) residing in the midgut of the phlebotomine vector to a non flagellated form (amastigote) invading the mammalian host. The cellular process for the conversion between these forms is an interesting biological phenomenon involving modulation of the plasma membrane. In this study, we describe a selective autophagic-like process during the in vitro differentiation of Leishmania mexicana promastigote to amastigote-like cells. This process is responsible for size reduction and shape change of the promastigote (15-20 MUm long) to the rounded amastigote-like form (4-5 MUm long), identical to the one that infects host macrophages. This autophagic-like process is characterized by a profound folding of the plasma membrane and the presence of abundant cytoplasmic lipid droplets that may be the product of changes in the lipid metabolism. The key feature for the differentiation process at either pH 7.0 or pH 5.5 is the shift in temperature from 25 to 35 degrees C. Flagella shortening during the differentiation process appears as the product of continuous flagellar microtubular disassembly that is also accompanied by changes in mitochondrion localization. Drugs directed at blocking the parasite autophagic-like process could be important as new strategies to fight the disease. PMID- 29170930 TI - Age-Specific Patient Navigation Preferences Among Adolescents and Young Adults with Cancer. AB - BACKGROUND: Patient navigation is increasingly being directed at adolescent and young adult (AYA) patients. This study provides a novel description of differences in AYA cancer patients' preferences for navigation services by developmental age at diagnosis. METHODS: Eligible patients were diagnosed with cancer between ages 15 and 39 and had completed at least 1 month of treatment. Between October 2015 and January 2016, patients completed semi-structured interviews about navigation preferences. Summary statistics of demographic and cancer characteristics were generated. Differences in patient navigation preferences were examined through qualitative analyses by developmental age at diagnosis. RESULTS: AYAs were interviewed (adolescents 15-18 years N = 8; emerging adults 19-25 years N = 8; young adults 26-39 years N = 23). On average, participants were 4.5 years from diagnosis. All age groups were interested in face-to-face connection with a navigator and using multiple communication platforms (phone, text, email) to follow-up. Three of the most frequently cited needs were insurance, finances, and information. AYAs differed in support, healthcare, and resource preferences by developmental age; only adolescents preferred educational support. While all groups preferred financial and family support, the specific type of assistance (medical versus living expenses, partner/spouse, child, or parental assistance) varied by age group. CONCLUSIONS: AYAs with cancer have different preferences for patient navigation by developmental age at diagnosis. AYAs are not a one-size-fits-all population, and navigation programs can better assist AYAs when services are targeted to appropriate developmental ages. Future research should examine fertility and navigation preferences by time since diagnosis. While some navigation needs to span the AYA age range, other needs are specific to developmental age.

AB - In the frame of a project which consists in modeling a laboratory microcosm under cadmium pressure, we initiated this study on the fate and effects of cadmium in the presence of either the microalga Pseudokirchneriella subcapitata or the duckweed Lemna minor, two organisms of the microcosm. For each organism, growth inhibition tests on a duration of 2-3 weeks were carried out with the objective of linking effects with total dissolved, ionic and internalized forms of cadmium. Numbers of organisms (algal cells or duckweed fronds) in 2-L beakers filled with synthetic nutritive medium containing EDTA were counted during the course of assays, while cadmium concentrations in the water and in the organisms were measured. Free cadmium fraction was calculated using PHREEQC, a computer program for chemical speciation. Results showed that cadmium toxicity to microalgae could be correlated to the free divalent fraction of this metal, limited by the presence of EDTA, and to its concentration in the organisms. Bioconcentration factors for our medium were suggested for P. subcapitata (111,000 on the basis of free cadmium concentration) and L. minor (17,812 on the basis of total dissolved concentration). No effect concentrations were roughly estimated around 400 ug/g for Pseudokirchneriella subcapitata and 200-300 ug/g for Lemna minor. This study is a first step towards a fate model based on chemical speciation for a better understanding of microcosm results. PMID- 29170932 TI - Estimating cross quantile residual ratio with left-truncated semi-competing risks data. AB - A semi-competing risks setting often arises in biomedical studies, involving both a nonterminal event and a terminal event. Cross quantile residual ratio (Yang and Peng in Biometrics 72:770-779, 2016) offers a flexible and robust perspective to study the dependency between the nonterminal and the terminal events which can shed useful scientific insight. In this paper, we propose a new nonparametric estimator of this dependence measure with left truncated semi-competing risks data. The new estimator overcomes the limitation of the existing estimator that is resulted from demanding a strong assumption on the truncation mechanism. We establish the asymptotic properties of the proposed estimator and develop inference procedures accordingly. Simulation studies suggest good finite-sample performance of the proposed method. Our proposal is illustrated via an application to Denmark diabetes registry data. PMID- 29170933 TI - Impact of previous episodes of hepatic encephalopathy on short-term brain function recovery after liver transplantation: a functional connectivity strength study. AB - Neuropsychological studies have documented an incomplete reversal of pre-existing cognitive dysfunction in cirrhotic patients after liver transplantation (LT) and have found this is more severe in patients with hepatic encephalopathy (HE). In this study, we aimed to investigate the impact of prior HE episodes on post transplantation brain function recovery. Resting-state functional magnetic resonance imaging data was collected from 30 healthy controls and 33 cirrhotic patients (HE, n = 15 and noHE, n = 18) before and one month after LT. Long- and short-range functional connectivity strength (FCS) analysis indicated that before transplantation both noHE and HE groups showed diffuse FCS abnormalities relative to healthy controls. For the noHE group, the abnormal FCS found before LT largely returned to normal levels after LT, except for in the cerebellum, precuneus, and orbital middle frontal gyrus. However, the abnormal FCS prior to LT was largely preserved in the HE group, including high-level cognition-related (frontal and parietal lobes) and vision-related areas (occipital lobe, cuneus, and precuneus). In addition, comparisons between HE and noHE groups revealed that weaker FCS in default mode network (DMN) in HE group persisted from pre- to post- LT. Correlation analysis showed that changes in FCS in the left postcentral and right middle frontal gyrus correlated with alterations in neuropsychological performance and ammonia levels. In conclusion, the findings in this study demonstrate potential adverse effects of pre-LT episode of HE on post-LT brain function recovery, and reveal that DMN may be the most affected brain region by HE episodes, which can't be reversed by LT.

AB - Portrayals of characters with autism spectrum disorder (ASD) and/or with autistic traits on film and in TV-series are increasing. Such portrayals may contribute in increasing awareness of the condition but can also increase stereotypes. Thus, these character portrayals are subject to heated debate within the ASD-community, but also in the general public at large. Following our recent published study on character portrayals of ASD on film and TV we here address some central issues related advantages and disadvantage of such portrayals. PMID- 29170935 TI - Predicting Internalizing and Externalizing Symptoms in Children with ASD: Evaluation of a Contextual Model of Parental Factors. AB - Parental adjustment, parenting behaviors, and child routines have been linked to internalizing and externalizing child behavior. The purpose of the present study was to evaluate a comprehensive model examining relations among these variables in children with ASD and their parents. Based on Sameroff's Transactional Model of Development (Sameroff in: The transactional model of development: How children and contexts shape each other, American Psychological Association, Washington, DC, 2009), researchers hypothesized that these factors would collectively predict child behavior. Parents (n = 67) completed measures of parental adjustment, parenting behaviors, child routines, and child behavior using the Hopkins Symptom Checklist, Alabama Parenting Questionnaire, Child Routines Inventory, and Child Behavior Checklist, respectively. Results indicated that parental adjustment predicted harsh/disengaged parenting (B = 0.17, p < .01) and internalizing behavior (B = 0.32, p < .01). Harsh/disengaged parenting and warm/supportive parenting predicted externalizing behavior (B = 0.59, p < .01) and internalizing behavior (B = - 0.49 p < .01), respectively. PMID- 29170936 TI - Symbolic Play in School-Aged Minimally Verbal Children with Autism Spectrum Disorder. AB - Few interventions exist for school-aged minimally verbal children with autism spectrum disorder (ASD). Even though play skills are associated with children's production of language, few studies have focused on play for minimally verbal children. Fifty-eight minimally verbal children with ASD received a naturalistic developmental behavioral intervention. Children were randomized to receive a speech generating device in the context of the intervention or not. Children in both conditions improved in play skills at exit. Children demonstrated an increase in play skills in proximal (sessions) and distal (during blind assessment) contexts. Minimally verbal children with ASD can improve their play skills within a targeted intervention. Increases in symbolic play were associated with increases in expressive language skills. PMID- 29170937 TI - Commentary on Social Skills Training Curricula for Individuals with ASD: Social Interaction, Authenticity, and Stigma. AB - By teaching social rules thought to be necessary for social competence, social skills training (SST) curricula aim to improve indicators of well-being for individuals with autism spectrum disorder (ASD), such as the attainment of meaningful friendships. However, several recent meta-analyses indicate that SST curricula may fall short of these goals. We offer an explanation for these potentially null effects by illustrating how the content of these curricula diverge from empirical evidence derived from disciplines that take social interaction as their object of study. Next, we argue that employing the social rules advocated for by SST curricula may work counterproductively by inhibiting authenticity, while at the same time increasing stigma associated with ASD. We close with suggestions for future intervention research. PMID- 29170938 TI - Feasibility of Parent Training via Telehealth for Children with Autism Spectrum Disorder and Disruptive Behavior: A Demonstration Pilot. AB - Telehealth is a potential solution to limited access to specialized services for children with autism spectrum disorder (ASD) in rural areas. We conducted a feasibility trial of parent training with children ages 3-8 with ASD and disruptive behavior from rural communities. Fourteen children (mean age 5.8 +/- 1.7) from four telehealth sites enrolled. Thirteen families (92.9%) completed treatment, with 91.6% of core sessions attended. Therapists attained 98% fidelity to the manual and 93% of expected outcome measures were collected at week 24. Eleven of 14 (78.6%) participants were rated as much/very much improved. Parent training via telehealth was acceptable to parents and treatment could be delivered reliably by therapists. Preliminary efficacy findings suggests further study is justified. PMID- 29170939 TI - Behavioral Outcomes of Specialized Psychiatric Hospitalization in the Autism Inpatient Collection (AIC): A Multisite Comparison. AB - Psychiatric hospitalization of children with autism spectrum disorder (ASD) is relatively common and occurs at a higher rate than in non-ASD youth. This study compared changes in the severity of serious problem behaviors in 350 youth with ASD enrolled in the autism inpatient collection during and after hospitalization in six specialized child psychiatry units. There was a significant reduction in serious problem behaviors from admission (aberrant behavior checklist irritability subscale M = 29.7, SD 9.6) to discharge (M = 15.0, SD 10.3) and 2 month follow-up (M = 19.3, SD 10.3). Between discharge and 2-month follow-up, tantrum-like behaviors but not self-injurious behaviors increased slightly. Improvement in the severity of problem behaviors was not uniform across sites, even after controlling for measured site differences. PMID- 29170940 TI - Association of Autism Spectrum Disorders and Inflammatory Bowel Disease. AB - Autism spectrum disorders (ASD) and inflammatory bowel disease (IBD) both have multifactorial pathogenesis with an increasing number of studies demonstrating gut-brain associations. We aim to examine the association between ASD and IBD using strict classification criteria for IBD. We conducted a retrospective case cohort study using records from the Military Health System database with IBD defined as having one encounter with an ICD-9-CM diagnostic code for IBD and at least one outpatient prescription dispensed for a medication to treat IBD. Children with ASD were more likely to meet criteria for Crohn's disease (CD) and Ulcerative colitis (UC) compared to controls. This higher prevalence of CD and UC in children with ASD compared to controls confirms the association of ASD with IBD. PMID- 29170941 TI - A Sibling-Mediated Intervention for Children with Autism Spectrum Disorder: Using the Natural Language Paradigm (NLP). AB - We taught three typically developing siblings to occasion speech by implementing the Natural Language Paradigm (NLP) with their brothers with autism spectrum disorder (ASD). A non-concurrent multiple baseline design across children with ASD and sibling dyads was used. Ancillary behaviors of happiness, play, and joint attention for the children with ASD were recorded. Generalization of speech for the children with ASD across setting and peers was also measured. During baseline, the children with ASD displayed few target speech behaviors and the siblings inconsistently occasioned speech from their brothers. After sibling training, however, they successfully delivered NLP, and in turn, for two of the brothers with ASD, speech reached criterion. Implications of this research suggest the inclusion of siblings in interventions. PMID- 29170942 TI - Refractive Status and Amblyopia Risk Factors in Chinese Children with Autism Spectrum Disorder. AB - Amblyopia risk factors in children with autism spectrum disorders (ASD) are usually hard to detect in early childhood due to poor cooperation and has not been reported in the Chinese population. We screened 168 Chinese children with ASD, aged between 3 and 8 years, and 264 age-matched neurotypical children with Spot photoscreener and basic ophthalmologic examinations. Children with ASD were found to have normal refractive status but significantly higher incidence of strabismus (16.1%), compared with control children (1.5%) (p < 0.01). Most of the cases of strabismus found in children with ASD were classified as esodeviation. Strabismus in children with ASD should be considered more seriously as an amblyopia risk factor by ophthalmologists and other healthcare professionals. PMID- 29170943 TI - Asenapine Treatment in Pediatric Patients with Bipolar I Disorder or Schizophrenia: A Review. AB - Asenapine, administered as a twice-daily (BID) sublingual tablet, is approved in the US as monotherapy for the acute treatment of manic and mixed episodes of bipolar I disorder in children and adolescents aged 10-17 years based on the positive results of one 3-week, double-blind, placebo-controlled study; the recommended dose is 2.5-10 mg BID. Although asenapine has been studied in pediatric patients with schizophrenia, it is not approved for this indication. Asenapine is not approved for pediatric use in bipolar I disorder or schizophrenia in other major markets. To inform clinicians treating psychiatric disorders in pediatric patients, we have summarized the neuropharmacology, pharmacokinetics, clinical trial experience, and clinical use of asenapine in pediatric patients. After rapid absorption through the oral mucosa, the pharmacokinetic profile of asenapine in pediatric patients is similar to that which is observed in adult patients, indicating that the recommended adult dosage does not need to be adjusted for pediatric use. Intake of food and water should be avoided for 10 min after administration. In clinical trials, asenapine was generally safe and well tolerated in pediatric patients with bipolar I disorder and schizophrenia. Serious adverse effects were generally related to worsening of the underlying psychiatric disorder. The most common treatment-emergent adverse events (TEAEs) in both indications were sedation and somnolence. Like some other second-generation antipsychotic agents, weight gain and changes in some metabolic parameters were noted; oral effects (e.g., oral hypoesthesia, dysgeusia, paresthesia) related to sublingual administration did not typically result in treatment discontinuation and were generally transient. Extrapyramidal symptom TEAEs occurred in >=5% of asenapine-treated patients in the acute and long-term studies in bipolar I disorder and schizophrenia.

AB - : Modulating the function of the insular cortex could be a novel therapeutic strategy to treat addiction to a variety of drugs of abuse as this region has been implicated in mediating drug reward and addictive processes. The recent advent of the H-coil has permitted the targeting of deeper brain structures which was not previously feasible. The goal of this study was to bilaterally target the insular region using the H-coil with repetitive Transcranial Magnetic Stimulation (rTMS) and subsequently measure changes in dopamine levels using Positron Emission Tomography (PET) with [11C]-(+)-propyl-hexahydro-naphtho-oxazin (PHNO). This was a within-subject, crossover, blinded and sham-controlled pilot study. Eight healthy, right-handed subjects, aged 19-45, participated in the investigation. All subjects underwent 3 PHNO-PET scans preceded by rTMS (sham, 1 Hz or 10 Hz), on 3 separate days. Low frequency rTMS (1 Hz), targeting the insular cortex, significantly decreased dopamine levels in the substantia nigra, sensorimotor striatum and associative striatum. Replicating this study in tobacco smokers or alcoholics would be a logical follow-up to assess whether H-coil stimulation of the bilateral insula can be employed as a treatment option for addiction.

AB - Despite national efforts to improve the public's education about an HIV diagnosis, stigma still plays a significant role in how persons living with HIV (PLH) decide to disclose their serostatus to friends, family, or healthcare workers. Disclosure can be related to both positive and negative psychological health outcomes, including rates of depression and perceived social support. Researchers often assess disclosure patterns in PLH due to its association with important health implications; however, to date, there are no empirically validated measures of HIV-serostatus disclosure. The HIV Disclosure Scale (HDS) was created to assess various aspects of the disclosure process and has been utilized in several studies as an adequate measurement of HIV-serostatus disclosure despite no available psychometric data. This study aims to uncover constructs measured by the HDS using exploratory two-step cluster analysis to provide an initial analysis of the psychometric properties of this scale.

AB - Limited research examines family planning for HIV-infected women with a history of injection drug use. We describe modern contraceptive use and its association with heavy drinking and recent injection for HIV-infected females in St. Petersburg, Russia (N = 49): 22.4% (n = 11) used traditional methods and 30.6% (n = 15) reported modern contraceptive use, which consisted primarily of condoms (26.5%, n = 13). Over 63% (n = 31) had an abortion. Observed associations for heavy alcohol use (AOR = 2.36, CI = 0.53, 12.41) and recent injection drug use (AOR = 2.88, CI = 0.60, 16.92) were clinically notable, but not statistically significant. Prioritizing family planning for HIV-infected women with a history of substance use is urgently needed.

AB - Using National HIV Behavioral Surveillance (NHBS) cross-sectional survey and HIV testing data in 21 U.S. metropolitan areas, we identify sex practices among sexually active men who have sex with men (MSM) associated with: (1) awareness of HIV status, and (2) engagement in the HIV care continuum. Data from 2008, 2011, and 2014 were aggregated, yielding a sample of 5079 sexually active MSM living with HIV (MLWH). Participants were classified into HIV status categories: (1) unaware; (2) aware and out of care; (3) aware and in care without antiretroviral therapy (ART); and (4) aware and on ART. Analyses were conducted examining sex practices (e.g. condomless sex, discordant condomless sex, and number of sex partners) by HIV status. Approximately 30, 5, 10 and 55% of the sample was classified as unaware, aware and out of care, aware and in care without ART, and aware and on ART, respectively. Unaware MLWH were more likely to report condomless anal sex with a last male partner of discordant or unknown HIV status (25.9%) than aware MLWH (18.0%, p value < 0.0001). Unaware MLWH were 3 times as likely to report a female sex partner in the prior 12 months as aware MLWH (17.3 and 5.6%, p-value < 0.0001). When examining trends across the continuum of care, reports of any condomless anal sex with a male partner in the past year (ranging from 65.0 to 70.0%), condomless anal sex with a male partner of discordant or unknown HIV status (ranging from 17.7 to 21.3%), and median number of both male and female sex partners were similar. In conclusion, awareness of HIV and engagement in care was not consistently associated with protective sex practices, highlighting the need for continued prevention efforts.

AB - A new methodology for crop-growth stage-specific assessment of agricultural drought risk under a variable sowing window is proposed for the soybean crop. It encompasses three drought indices, which include Crop-Specific Drought Index (CSDI), Vegetation Condition Index (VCI), and Standardized Precipitation Evapotranspiration Index (SPEI). The unique features of crop-growth stage specific nature and spatial and multi-scalar coverage provide a comprehensive assessment of agricultural drought risk. This study was conducted in 10 major soybean-growing districts of Madhya Pradesh state of India. These areas contribute about 60% of the total soybean production for the country. The phenophase most vulnerable to agricultural drought was identified (germination and flowering in our case) for each district across four sowing windows. The agricultural drought risk was quantified at various severity levels (moderate, severe, and very severe) for each growth stage and sowing window. Validation of the proposed new methodology also yielded results with a high correlation coefficient between percent probability of agricultural drought risk and yield risk (r = 0.92). Assessment by proximity matrix yielded a similar statistic. Expectations for the proposed methodology are better mitigation-oriented management and improved crop contingency plans for planners and decision makers. PMID- 29170949 TI - Parts Characterization for Tunable Protein Expression. AB - Flow-seq combines flexible genome engineering methods with flow cytometry-based cell sorting and deep DNA sequencing to enable comprehensive interrogation of genotype to phenotype relationships. One application is to study the effect of specific regulatory elements on protein expression. Constructing targeted genomic variation around genomically integrated fluorescent marker genes enables rapid elucidation of the contribution of specific sequence variants to protein expression. Such an approach can be used to characterize the impact of modifications to the Shine-Dalgarno sequence in Escherichia coli. PMID- 29170950 TI - Enzyme Nicotinamide Cofactor Specificity Reversal Guided by Automated Structural Analysis and Library Design. AB - The specificity of enzymes for nicotinamide adenine dinucleotide (NAD) or nicotinamide adenine dinucleotide phosphate (NADP) as redox carriers can pose a significant hurdle for metabolic engineering and synthetic biology applications, where switching the specificity might be beneficial. We have developed an easy-to use computational tool (CSR-SALAD) for the design of mutant libraries to simplify the process of reversing the cofactor specificity of an enzyme. Here, we describe the optimal use of this tool and present methods for its application in a laboratory setting. PMID- 29170951 TI - Bacterial Genome Editing Strategy for Control of Transcription and Protein Stability. AB - In molecular biology and cell factory engineering, tools that enable control of protein production and stability are highly important. Here, we describe protocols for tagging genes in Escherichia coli allowing for inducible degradation and transcriptional control of any soluble protein of interest. The underlying molecular biology is based on the two cross-kingdom tools CRISPRi and the N-end rule for protein degradation. Genome editing is performed with the CRMAGE technology and randomization of the translational initiation region minimizes the polar effects of tag insertion. The approach has previously been applied for targeting proteins originating from essential operon-located genes and has potential to serve as a universal synthetic biology tool. PMID- 29170952 TI - An Automated Pipeline for Engineering Many-Enzyme Pathways: Computational Sequence Design, Pathway Expression-Flux Mapping, and Scalable Pathway Optimization. AB - Engineering many-enzyme metabolic pathways suffers from the design curse of dimensionality. There are an astronomical number of synonymous DNA sequence choices, though relatively few will express an evolutionary robust, maximally productive pathway without metabolic bottlenecks. To solve this challenge, we have developed an integrated, automated computational-experimental pipeline that identifies a pathway's optimal DNA sequence without high-throughput screening or many cycles of design-build-test. The first step applies our Operon Calculator algorithm to design a host-specific evolutionary robust bacterial operon sequence with maximally tunable enzyme expression levels. The second step applies our RBS Library Calculator algorithm to systematically vary enzyme expression levels with the smallest-sized library. After characterizing a small number of constructed pathway variants, measurements are supplied to our Pathway Map Calculator algorithm, which then parameterizes a kinetic metabolic model that ultimately predicts the pathway's optimal enzyme expression levels and DNA sequences. Altogether, our algorithms provide the ability to efficiently map the pathway's sequence-expression-activity space and predict DNA sequences with desired metabolic fluxes. Here, we provide a step-by-step guide to applying the Pathway Optimization Pipeline on a desired multi-enzyme pathway in a bacterial host. PMID- 29170953 TI - Computational Approaches on Stoichiometric and Kinetic Modeling for Efficient Strain Design. AB - Engineering biological systems that are capable of overproducing products of interest is the ultimate goal of any biotechnology application. To this end, stoichiometric (or steady state) and kinetic models are increasingly becoming available for a variety of organisms including prokaryotes, eukaryotes, and microbial communities. This ever-accelerating pace of such model reconstructions has also spurred the development of optimization-based strain design techniques. This chapter highlights a number of such frameworks developed in recent years in order to generate testable hypotheses (in terms of genetic interventions), thus addressing the challenges in metabolic engineering. In particular, three major methods are covered in detail including two methods for designing strains (i.e., one stoichiometric model-based and the other by integrating kinetic information into a stoichiometric model) and one method for analyzing microbial communities. PMID- 29170954 TI - Extended Metabolic Space Modeling. AB - Determining the fraction of the chemical space that can be processed in vivo by using natural and synthetic biology devices is crucial for the development of advanced synthetic biology applications. The extended metabolic space is a coding system based on molecular signatures that enables the derivation of reaction rules for metabolic reactions and the enumeration of all possible substrates and products corresponding to the rules. The extended metabolic space expands capabilities for controlling the production, processing, sensing, and the release of specific molecules in chassis organisms. PMID- 29170955 TI - Computational Methods to Assess the Production Potential of Bio-Based Chemicals. AB - Elevated costs and long implementation times of bio-based processes for producing chemicals represent a bottleneck for moving to a bio-based economy. A prospective analysis able to elucidate economically and technically feasible product targets at early research phases is mandatory. Computational tools can be implemented to explore the biological and technical spectrum of feasibility, while constraining the operational space for desired chemicals. In this chapter, two different computational tools for assessing potential for bio-based production of chemicals from different perspectives are described in detail. The first tool is GEM-Path: an algorithm to compute all structurally possible pathways from one target molecule to the host metabolome. The second tool is a framework for Modeling Sustainable Industrial Chemicals production (MuSIC), which integrates modeling approaches for cellular metabolism, bioreactor design, upstream/downstream processes, and economic impact assessment. Integrating GEM-Path and MuSIC will play a vital role in supporting early phases of research efforts and guide the policy makers with decisions, as we progress toward planning a sustainable chemical industry. PMID- 29170956 TI - Multiplex Genome Editing in Escherichia coli. AB - Lambda Red recombineering is an easy and efficient method for generating genetic modifications in Escherichia coli. For gene deletions, lambda Red recombineering is combined with the use of selectable markers, which are removed through the action of, e.g., flippase (Flp) recombinase. This PCR-based engineering method has also been applied to a number of other bacteria. In this chapter, we describe a recently developed one plasmid-based method as well as the use of a strain with genomically integrated recombineering genes, which significantly speeds up the engineering of strains with multiple genomic alterations. PMID- 29170957 TI - Designing and Implementing Algorithmic DNA Assembly Pipelines for Multi-Gene Systems. AB - Advances in DNA synthesis and assembly technology allow for the high-throughput fabrication of hundreds to thousands of multi-part genetic constructs in a short time. This allows for rapid hypothesis-testing and genetic optimization in multi gene biological systems. Here, we discuss key considerations to design and implement an algorithmic DNA assembly pipeline that provides the freedom to change nearly any design variable in a multi-gene system. In addition to considerations for pipeline design, we describe protocols for three useful molecular biology techniques in plasmid construction. PMID- 29170958 TI - An Adaptive Laboratory Evolution Method to Accelerate Autotrophic Metabolism. AB - Adaptive laboratory evolution (ALE) is an approach enabling the development of novel characteristics in microbial strains via the application of a constant selection pressure. This method is also an efficient tool to acquire insights on molecular mechanisms responsible for specific phenotypes. ALE experiments have mainly been conducted with heterotrophic microbes to study, for instance, cell metabolism with different multicarbon substrates, tolerance to solvents, pH variation, and high temperature. Here, we describe employing an ALE method to generate Sporomusa ovata strains growing faster autotrophically and reducing CO2 into acetate more efficiently. Strains developed via this ALE method were also used to gain knowledge on the autotrophic metabolism of S. ovata as well as other acetogenic bacteria. PMID- 29170959 TI - CRISPR-Cas9 Toolkit for Actinomycete Genome Editing. AB - Bacteria of the order Actinomycetales are one of the most important sources of bioactive natural products, which are the source of many drugs. However, many of them still lack efficient genome editing methods, some strains even cannot be manipulated at all. This restricts systematic metabolic engineering approaches for boosting known and discovering novel natural products. In order to facilitate the genome editing for actinomycetes, we developed a CRISPR-Cas9 toolkit with high efficiency for actinomyces genome editing. This basic toolkit includes a software for spacer (sgRNA) identification, a system for in-frame gene/gene cluster knockout, a system for gene loss-of-function study, a system for generating a random size deletion library, and a system for gene knockdown. For the latter, a uracil-specific excision reagent (USER) cloning technology was adapted to simplify the CRISPR vector construction process. The application of this toolkit was successfully demonstrated by perturbation of genomes of Streptomyces coelicolor A3(2) and Streptomyces collinus Tu 365. The CRISPR-Cas9 toolkit and related protocol described here can be widely used for metabolic engineering of actinomycetes. PMID- 29170960 TI - Assembly and Multiplex Genome Integration of Metabolic Pathways in Yeast Using CasEMBLR. AB - Genome integration is a vital step for implementing large biochemical pathways to build a stable microbial cell factory. Although traditional strain construction strategies are well established for the model organism Saccharomyces cerevisiae, recent advances in CRISPR/Cas9-mediated genome engineering allow much higher throughput and robustness in terms of strain construction. In this chapter, we describe CasEMBLR, a highly efficient and marker-free genome engineering method for one-step integration of in vivo assembled expression cassettes in multiple genomic sites simultaneously. CasEMBLR capitalizes on the CRISPR/Cas9 technology to generate double-strand breaks in genomic loci, thus prompting native homologous recombination (HR) machinery to integrate exogenously derived homology templates. As proof-of-principle for microbial cell factory development, CasEMBLR was used for one-step assembly and marker-free integration of the carotenoid pathway from 15 exogenously supplied DNA parts into three targeted genomic loci. As a second proof-of-principle, a total of ten DNA parts were assembled and integrated in two genomic loci to construct a tyrosine production strain, and at the same time knocking out two genes. This new method complements and improves the field of genome engineering in S. cerevisiae by providing a more flexible platform for rapid and precise strain building. PMID- 29170961 TI - A Modified Gibson Assembly Method for Cloning Large DNA Fragments with High GC Contents. AB - Gibson one-step, isothermal assembly method (Gibson assembly) can be used to efficiently assemble large DNA molecules by in vitro recombination involving a 5' exonuclease, a DNA polymerase and a DNA ligase. In the past few years, this robust DNA assembly method has been widely applied to seamlessly construct genes, genetic pathways and even entire genomes. Here, we expand this method to clone large DNA fragments with high GC contents, such as antibiotic biosynthetic gene clusters from Streptomyces . Due to the low isothermal condition (50 degrees C) in the Gibson reaction system, the complementary overlaps with high GC contents are proposed to easily form mismatched linker pairings, which leads to low assembly efficiencies mainly due to vector self-ligation. So, we modified this classic method by the following two steps. First, a pair of universal terminal single-stranded DNA overhangs with high AT contents are added to the ends of the BAC vector. Second, two restriction enzyme sites are introduced into the respective sides of the designed overlaps to achieve the hierarchical assembly of large DNA molecules. The optimized Gibson assembly method facilitates fast acquisition of large DNA fragments with high GC contents from Streptomyces. PMID- 29170962 TI - Coupling Yeast Golden Gate and VEGAS for Efficient Assembly of the Violacein Pathway in Saccharomyces cerevisiae. AB - The ability to express non-native pathways in genetically tractable model systems is important for fields such as synthetic biology, genetics, and metabolic engineering. Here we describe a modular and hierarchical strategy to assemble multigene pathways for expression in S. cerevisiae. First, discrete promoter, coding sequence, and terminator parts are assembled in vitro into Transcription Units (TUs) flanked by adapter sequences using "yeast Golden Gate" (yGG), a type IIS restriction enzyme-dependent cloning strategy. Next, harnessing the natural capacity of S. cerevisiae for homologous recombination, TUs are assembled into pathways and expressed using the "Versatile Genetic Assembly System" (VEGAS) in yeast. Coupling transcription units constructed by yGG with VEGAS assembly is a generic and flexible workflow to achieve pathway expression in S. cerevisiae. This protocol describes assembly of a five TU pathway for yeast production of violacein, a pigment derived from Chromobacterium violaceum. PMID- 29170963 TI - Multi-capillary Column Ion Mobility Spectrometry of Volatile Metabolites for Phenotyping of Microorganisms. AB - Rational strain engineering requires solid testing of phenotypes including productivity and ideally contributes thereby directly to our understanding of the genotype-phenotype relationship. Actually, the test step of the strain engineering cycle becomes the limiting step, as ever advancing tools for generating genetic diversity exist. Here, we briefly define the challenge one faces in quantifying phenotypes and summarize existing analytical techniques that partially overcome this challenge. We argue that the evolution of volatile metabolites can be used as proxy for cellular metabolism. In the simplest case, the product of interest is a volatile (e.g., from bulk alcohols to special fragrances) that is directly quantified over time. But also nonvolatile products (e.g., from bulk long-chain fatty acids to natural products) require major flux rerouting that result potentially in altered volatile production. While alternative techniques for volatile determination exist, rather few can be envisaged for medium to high-throughput analysis required for phenotype testing. Here, we contribute a detailed protocol for an ion mobility spectrometry (IMS) analysis that allows volatile metabolite quantification down to the ppb range. The sensitivity can be exploited for small-scale fermentation monitoring. The insights shared might contribute to a more frequent use of IMS in biotechnology, while the experimental aspects are of general use for researchers interested in volatile monitoring. PMID- 29170964 TI - Selection of Highly Expressed Gene Variants in Escherichia coli Using Translationally Coupled Antibiotic Selection Markers. AB - Strategies to select highly expressed variants of a protein coding sequence are usually based on trial-and-error approaches, which are time-consuming and expensive. We address this problem using translationally coupled antibiotic resistance markers. The system requires that the target gene can be fused at the 3'-end with a translational coupling element and an antibiotic resistance gene. Highly expressed target genes can then be selected using a fast and simple whole cell survival assay in the presence of high antibiotic concentrations. Herein we show that the system can be used to select highly expressing clones from libraries sampling translation initiation sites. PMID- 29170965 TI - Design, Engineering, and Characterization of Prokaryotic Ligand-Binding Transcriptional Activators as Biosensors in Yeast. AB - In cell factory development, screening procedures, often relying on low throughput analytical methods, are lagging far behind diversity generation methods. This renders the identification and selection of the best cell factory designs tiresome and costly, conclusively hindering the manufacturing process. In the yeast Saccharomyces cerevisiae, implementation of allosterically regulated transcription factors from prokaryotes as metabolite biosensors has proven a valuable strategy to alleviate this screening bottleneck. Here, we present a protocol to select and incorporate prokaryotic transcriptional activators as metabolite biosensors in S. cerevisiae. As an example, we outline the engineering and characterization of the LysR-type transcriptional regulator (LTTR) family member BenM from Acetinobacter sp. ADP1 for monitoring accumulation of cis,cis muconic acid, a bioplast precursor, in yeast by means of flow cytometry. PMID- 29170966 TI - A Capture-SELEX Strategy for Multiplexed Selection of RNA Aptamers Against Small Molecules. AB - In vitro selection of aptamers that recognize small organic molecules has proven difficult, in part due to the challenge of immobilizing small molecules on solid supports for SELEX (Systematic Evolution of Ligands by Exponential Enrichment). This study describes the implementation of RNA Capture-SELEX, a selection strategy that uses an RNA library to yield ligand-responsive RNA aptamers targeting small organic molecules in solution. To demonstrate the power of this method we selected several aptamers with specificity towards either the natural sweetener rebaudioside A or the food-coloring agent carminic acid. In addition, Bio-layer interferometry is used to screen clonal libraries of aptamer candidates and is used to interrogate aptamer affinity. The RNA-based Capture-SELEX strategy described here simplifies selection of RNA aptamers against small molecules by avoiding ligand immobilization, while also allowing selection against multiple candidate targets in a single experiment. This makes RNA Capture-SELEX particularly attractive for accelerated development of RNA aptamers targeting small metabolites for incorporation into synthetic riboswitches and for analytical biosensors. PMID- 29170967 TI - High-Throughput Microfluidics for the Screening of Yeast Libraries. AB - Cell factory development is critically important for efficient biological production of chemicals, biofuels, and pharmaceuticals. Many rounds of the Design Build-Test-Learn cycles may be required before an engineered strain meeting specific metrics required for industrial application. The bioindustry prefer products in secreted form (secreted products or extracellular metabolites) as it can lower the cost of downstream processing, reduce metabolic burden to cell hosts, and allow necessary modification on the final products , such as biopharmaceuticals. Yet, products in secreted form result in the disconnection of phenotype from genotype, which may have limited throughput in the Test step for identification of desired variants from large libraries of mutant strains. In droplet microfluidic screening, single cells are encapsulated in individual droplet and enable high-throughput processing and sorting of single cells or clones. Encapsulation in droplets allows this technology to overcome the throughput limitations present in traditional methods for screening by extracellular phenotypes. In this chapter, we describe a protocol/guideline for high-throughput droplet microfluidics screening of yeast libraries for higher protein secretion . This protocol can be adapted to screening by a range of other extracellular products from yeast or other hosts. PMID- 29170968 TI - Growth-Coupled Carotenoids Production Using Adaptive Laboratory Evolution. AB - Adaptive laboratory evolution is a powerful technique for strain development. However, the target phenotypes using this strategy have been limited by the required coupling of the phenotype-of-interest with fitness or survival, and thus adaptive evolution is generally not used to improve product formation. If the desired product confers a benefit to the host, then adaptive evolution can be an effective approach to improve host productivity. In this book chapter, we describe an effective adaptive laboratory evolution strategy for improving product formation of carotenoids, a class of compounds with antioxidant potential, in the yeast Saccharomyces cerevisiae. PMID- 29170969 TI - Two-Scale 13C Metabolic Flux Analysis for Metabolic Engineering. AB - Accelerating the Design-Build-Test-Learn (DBTL) cycle in synthetic biology is critical to achieving rapid and facile bioengineering of organisms for the production of, e.g., biofuels and other chemicals. The Learn phase involves using data obtained from the Test phase to inform the next Design phase. As part of the Learn phase, mathematical models of metabolic fluxes give a mechanistic level of comprehension to cellular metabolism, isolating the principle drivers of metabolic behavior from the peripheral ones, and directing future experimental designs and engineering methodologies. Furthermore, the measurement of intracellular metabolic fluxes is specifically noteworthy as providing a rapid and easy-to-understand picture of how carbon and energy flow throughout the cell. Here, we present a detailed guide to performing metabolic flux analysis in the Learn phase of the DBTL cycle, where we show how one can take the isotope labeling data from a 13C labeling experiment and immediately turn it into a determination of cellular fluxes that points in the direction of genetic engineering strategies that will advance the metabolic engineering process.For our modeling purposes we use the Joint BioEnergy Institute (JBEI) Quantitative Metabolic Modeling (jQMM) library, which provides an open-source, python-based framework for modeling internal metabolic fluxes and making actionable predictions on how to modify cellular metabolism for specific bioengineering goals. It presents a complete toolbox for performing different types of flux analysis such as Flux Balance Analysis, 13C Metabolic Flux Analysis, and it introduces the capability to use 13C labeling experimental data to constrain comprehensive genome-scale models through a technique called two-scale 13C Metabolic Flux Analysis (2S-13C MFA) [1]. In addition to several other capabilities, the jQMM is also able to predict the effects of knockouts using the MoMA and ROOM methodologies. The use of the jQMM library is illustrated through a step-by-step demonstration, which is also contained in a digital Jupyter Notebook format that enhances reproducibility and provides the capability to be adopted to the user's specific needs. As an open-source software project, users can modify and extend the code base and make improvements at will, providing a base for future modeling efforts.

AB - INTRODUCTION: We conducted a study at two main centres for paediatric surgery in the Republic of Ireland, Temple Street Children's University Hospital (TSCUH) and Our Lady's Children's Hospital Crumlin (OLCHC). AIM: The aim of the study was to assess doctors' opinions, frequency and methods of smartphone use in clinical practice. METHODS: Doctors (n = 265) at the two hospitals were invited to complete a 12-item survey. Descriptive statistics were calculated accordingly. RESULTS: Almost 50% (132/256) responded; 98.4% owned a smartphone and 76% owned an iPhone. Seventy-nine percent used medical apps and 59% used the OLCHC formulary. Ninety-seven percent used smartphones for inter-team communication with 73.5% (n = 97) using WhatsApp. Smartphone camera was used by 57% for clinical photos and 41% for photos of radiological imaging. Only 42% reported obtaining consent for smartphone camera use from patients or guardians. Ninety two percent either 'strongly agreed' or 'agreed' that smartphones positively impact their practice. CONCLUSION: Smartphone usage is universal among healthcare professionals and their influence is growing in patient care. PMID- 29170972 TI - The accessibility and utilization of genetic testing for inherited heart rhythm disorders: a Canadian cross-sectional survey study. AB - The genetic basis of many sudden death-related conditions has been elucidated. These include inherited arrhythmias and arrhythmogenic cardiomyopathies, termed inherited heart rhythm disorders (IHRD). Advising on and interpreting genetic testing is challenging for the general cardiologist. This has led to the development of interdisciplinary clinics for IHRD in varying stages of establishment in Canada. We sought the viewpoints and patterns of practice of Canadian IHRD experts, and assessed their ability to access genetic testing for IHRD using a national cross-sectional survey. Of 56 participants, most were physicians (68%) or genetic counselors (19%). Despite working collaboratively, most genetic counselors (59%) were either not satisfied or only somewhat satisfied with their relationships with physicians. Ninety percent of participants were involved in offering genetic evaluation, including 80% who felt that testing was usually/always accessible. Most offered genetic testing to confirm clinical diagnosis and/or direct family screening. Post-mortem genetic analysis was sought by 69% of respondents; however, a lack of retained tissue and/or poor tissue preparation hindered this process. Family screening was usually recommended in the setting of a pathogenic/likely pathogenic variant. The most commonly perceived barrier to genetic testing was cost to the healthcare system. More than a quarter of patients waited >= 6 months for funding. An ability to engage at-risk relatives was rated as limited/poor by 34% of participants. Despite the establishment of several interdisciplinary clinics, timely access to affordable testing, supported by strong team communication, continues to be a barrier to genetic testing in Canada. PMID- 29170971 TI - Assembly and remodeling of viral DNA and RNA replicons regulated by cellular molecular chaperones. AB - A variety of cellular reactions mediated by interactions among proteins and nucleic acids requires a series of proteins called molecular chaperones. The viral genome encodes relatively few kinds of viral proteins and, therefore, host derived cellular factors are required for virus proliferation. Here we discuss those cellular proteins known as molecular chaperones, which are essential for the assembly of functional viral DNA/RNA replicons. The function of these molecular chaperones in the cellular context is also discussed. PMID- 29170973 TI - Primary acute angle-closure glaucoma complicating ciliochoroidal detachment: report of four cases and review of the literature. AB - PURPOSE: To describe the ultrasound biomicroscopy (UBM) and B-scan ultrasonography findings and therapeutic approach for ciliochoroidal detachment secondary to acute primary angle-closure glaucoma (APACG) in four patients. We also reviewed the literature. METHODS: Case report and systematic literature review. RESULTS: The four patients were referred to our department for further management of APACG. The UBM and B-scan ultrasonography examinations were conducted 2 days after the beginning of medical treatment and demonstrated ciliochoroidal detachment in four eyes of the four patients. The patients all received intravenous infusion of corticosteroid therapy (10 mg dexamethasone once daily for 5-7 days). We reviewed the UBM findings, which confirmed that the ciliochoroidal detachment disappeared. The patients then underwent trabeculectomy combined with peripheral iridotomy surgery. The patients all ultimately recovered very well. CONCLUSION: APACG with ciliochoroidal detachment is rare and has hidden clinical manifestations, and the pathophysiological mechanism is not yet fully understood. Anti-glaucoma surgery may increase the detachment. UBM and B scan ultrasounds are useful tools for ciliochoroidal detachment diagnosis in APACG patients before operative treatment. PMID- 29170974 TI - Comparative proteomic analysis of amnion membrane transplantation and cross linking treatments in an experimental alkali injury model. AB - PURPOSE: In this study, by using a two-dimensional (2D) electrophoresis-based experimental approach, we aimed at understanding the nature of alkali injuries and the underlying mechanisms. A secondary aim was to compare the effects of cross-linking (CXL) and amnion membrane transplantation (AMT) on corneal protein compositions at the end of the early repair phase after injured with alkali. METHOD: The right corneas of 24 rabbits were injured with a 1 N solution of NaOH. Groups were formed based on the adjuvant therapies as (1) healthy group, (2) control group, (3) CXL group, (4) AMT group. In addition to the therapies, a conventional medical treatment was applied to all groups. Left eyes were used as within-subject healthy corneas (1). The corneas were excised at day 21, and a comparative proteomic analysis was performed using 2D gel electrophoresis coupled with MALDI-TOF/TOF. RESULT: 2D gel electrophoresis revealed the presence seven protein spots whose abundance changed among the groups. Those proteins were SH3 domain-binding protein, plant homeodomain finger protein 23, S100 calcium binding protein A-11(S100 A11), keratin type 2 cytoskeletal 1 and 2, transketolase and glyceraldehyde 3-phosphate dehydrogenase. Ingenuity pathway analysis predicted that the observed changes may be linked to a central metabolic pathway, transforming growth factor beta 1. Canonical pathway analysis focused our attention to two different pathways, namely nicotinamide adenine dinucleotide repair pathway and non-oxidative branch of pentose phosphate pathway. CONCLUSION: Our results shed some light onto the molecular mechanisms affected by alkali injury and adjuvant treatments. Further research is needed to propose medically significant target molecules that may be used for novel drug developments for alkali injury. PMID- 29170975 TI - Utility of superiorly based platysma myocutaneous flap for reconstruction of intraoral surgical defects: our experience. AB - PURPOSE: Various surgical modalities have been advocated for the soft tissue reconstruction of oral cavity with variable results. This prospective study evaluates the utility of platysma myocutaneous flap (PMF) in the reconstruction of surgical defects followed by treatment of oral submucous fibrosis (OSMF) and oral squamous cell carcinoma (OSCC) in terms of healing and functional outcomes. METHODS: In this prospective study, 47 patients with OSMF and 15 of OSCC were evaluated and selected for PMF reconstruction. OSCC was selected under T1N0M0 category only. Patients were operated under general anaesthesia followed by PMF grafting. In OSCC, ipsilateral and for OSMF, bilateral PMF was used. RESULTS: In 47 patients treated for OSMF, 46 were male and 1 female while 15 cases of OSCC, 10 were male and 5 females aged between 18 and 44 years. Intraoperative mouth opening was achieved up to 48 mm in OSMF followed by 42.5 mm postoperatively after 2 years. However, uneventful healing and acceptable scar on cervical region was noted in all the cases including OSCC. In OSMF, three cases of dehiscence, four partial necrosis at end of flap and in OSCC one case shows skin loss at flap and two partial necrosis at tip of flap and extraoral localised abscess at ipsilateral donor site in one case was noted. An uneventful healing, anatomical form and functional results were restored with acceptable scarring at donor site without any evidence of difficulty in neck movements were observed. CONCLUSION: The PMF is simple, versatile and could be valued as a reconstructive alternative, with interesting visual qualities. It is a good therapeutic alternative tool for reconstruction of the buccal mucosa, especially for small- and medium-sized defects between 2 and 4 cm2 of the oral cavity. PMID- 29170976 TI - Real-world treatment in patients with HER2+ metastatic breast cancer : Treatment decisions in HER2+ mBC. AB - PURPOSE: The landscape of HER2+ metastatic breast cancer (mBC) treatment is changing due to the availability of new anti-HER2 drugs. The purpose of this study was to assess the current treatment patterns and sequences used in HER2+ mBC in the real-world setting. Secondary objectives were to describe the factors that influence the decision to prescribe a first and second-line antitumour treatment. METHODS: Retrospective chart review of 3068 cases in Spain, Italy, the Netherlands and the UK. RESULTS: First and second-line treatments and regimens are consistent with the clinical guidelines, especially for recently initiated treatments. Age and performance status (PS) of patients impact treatment patterns: younger patients received more innovative treatments than elderly patients. In addition, while most patients received a first antitumor treatment, the rate of patients who continue to subsequent lines of therapy is low (55% transitioning from 1st to 2nd line; 58% from 2nd to 3rd line). Age and PS are key factors in the decision to prescribe further antitumor treatment. CONCLUSION: Fewer HER2+ mBC patients than expected receive a second and third line therapy. Guidelines should make specific recommendations for older patients or those with a poor PS. PMID- 29170977 TI - Species differences and mechanism of action of A3 adenosine receptor allosteric modulators. AB - Activity of the A3 adenosine receptor (AR) allosteric modulators LUF6000 (2 cyclohexyl-N-(3,4-dichlorophenyl)-1H-imidazo [4,5-c]quinolin-4-amine) and LUF6096 (N-{2-[(3,4-dichlorophenyl)amino]quinolin-4-yl}cyclohexanecarbox-amide) was compared at four A3AR species homologs used in preclinical drug development. In guanosine 5'-[gamma-[35S]thio]triphosphate ([35S]GTPgammaS) binding assays with cell membranes isolated from human embryonic kidney cells stably expressing recombinant A3ARs, both modulators substantially enhanced agonist efficacy at human, dog, and rabbit A3ARs but provided only weak activity at mouse A3ARs. For human, dog, and rabbit, both modulators increased the maximal efficacy of the A3AR agonist 2-chloro-N 6-(3-iodobenzyl)adenosine-5'-N-methylcarboxamide as well as adenosine > 2-fold, while slightly reducing potency in human and dog. Based on results from N 6-(4-amino-3-[125I]iodobenzyl)adenosine-5'-N-methylcarboxamide ([125I]I-AB-MECA) binding assays, we hypothesize that potency reduction is explained by an allosterically induced slowing in orthosteric ligand binding kinetics that reduces the rate of formation of ligand-receptor complexes. Mutation of four amino acid residues of the human A3AR to the murine sequence identified the extracellular loop 1 (EL1) region as being important in selectively controlling the allosteric actions of LUF6096 on [125I]I-AB-MECA binding kinetics. Homology modeling suggested interaction between species variable EL1 and agonist-contacting EL2. These results indicate that A3AR allostery is species-dependent and provide mechanistic insights into this therapeutically promising class of agents. PMID- 29170978 TI - Implementing a screening tool to improve prescribing in hospitalized older patients: a pilot study. AB - Background The use of STOPP-START criteria during hospitalization reduced inappropriate medications in randomized controlled trials. Objective To evaluate whether the implementation of a screening tool (short version of STOPP-START criteria) in routine geriatric practice reduces potentially inappropriate medications (PIM) and potential prescribing omissions (PPO) at discharge. Methods We conducted a retrospective interrupted time series analysis. Four periods were selected between February and September 2013: (1) baseline situation; (2) screening tool made available to physicians; (3) 3 months later; (4) weekly meetings with junior doctors and a clinical pharmacist to review treatments according to the tool. The primary outcome was the proportion of patients with prescribing improvement from admission to discharge. Results We included 120 patients (median age 85 years). The prevalence of PIMs and PPOs on admission was 56% (67/120) and 51% (61/120) respectively. Hospitalization improved prescribing appropriateness in 49% of patients with PIMs (33/67) and 39% of patients with PPOs (24/61). The use of the screening tool by way of multidisciplinary meetings was a predictor of PIMs reduction at discharge. Conclusions The sole distribution of a screening tool in a geriatric unit did not reduce PIMs and PPOs. Multidisciplinary meetings to review treatments should be encouraged. PMID- 29170979 TI - Predictors of changes in disease activity among children with juvenile dermatomyositis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Legacy Registry. AB - Determinants of changes in disease activity among patients with juvenile dermatomyositis (JDM) are unknown. Our objective was to develop predictive models to predict changes in disease activity using the CARRA Legacy Registry. The CARRA Legacy Registry included 658 subjects with definite or probably JDM with 297 subjects with a one follow-up visit after baseline, and we studied the 65 subjects with active disease at baseline. Linear regression models were used to build risk scores for changes in disease activity adjusted for baseline disease activity, age, sex, and disease duration. Disease activity improved from baseline to 6-month follow-up as measured by patient/parent global health score (median 4; p = 0.008), patient pain score (median 2; p = 0.014), physician global (median 4; p < 0.001), and Childhood Myositis Assessment Scale (CMAS) (median 41, p < 0.001). Anti-nuclear antibodies (p = 0.013) and hydroxychloroquine use (p = 0.045) were significant predictors of less improvement in patient/parent global and baseline patient/parent global. Anti-nuclear antibodies (p = 0.001) and V/shawl sign (p = 0.005) were significant predictors of less improvement in patient pain (R-square improved from 0.29 for adjustors alone to 0.46 for the full model). Small joint arthritis (p < 0.01) predicted less improvement and dysphagia/dysphonia (p = 0.033) predicted greater improvement in CMAS and baseline CMAS (R-square improved from 0.73 for adjustors alone to 0.86 for the full model). Disease characteristics can help identify patients who are less likely to improve over time. Risk scores to predict future changes in disease activity could be used to trigger more aggressive treatment earlier in the disease course. PMID- 29170980 TI - From electromyographic activity to frequency modulation in zebra finch song. AB - Behavior emerges from the interaction between the nervous system and peripheral devices. In the case of birdsong production, a delicate and fast control of several muscles is required to control the configuration of the syrinx (the avian vocal organ) and the respiratory system. In particular, the syringealis ventralis muscle is involved in the control of the tension of the vibrating labia and thus affects the frequency modulation of the sound. Nevertheless, the translation of the instructions (which are electrical in nature) into acoustical features is complex and involves nonlinear, dynamical processes. In this work, we present a model of the dynamics of the syringealis ventralis muscle and the labia, which allows calculating the frequency of the generated sound, using as input the electrical activity recorded in the muscle. In addition, the model provides a framework to interpret inter-syllabic activity and hints at the importance of the biomechanical dynamics in determining behavior. PMID- 29170982 TI - Subcallosal and Heubner artery infarcts following surgical repair of an anterior communicating artery aneurysm: a causal relationship with postoperative amnesia and long-term outcome. AB - Since the 1950s, amnesia or memory impairment has been repeatedly reported in patients following surgical repair of anterior communicating artery (ACoA) aneurysms. Postoperative infarctions following surgical repair of ACoA aneurysms are classified as involvement of the subcallosal artery (the largest unpaired perforator of the ACoA), the recurrent artery of Heubner (RAH), or a combination of both. Postoperative amnesia can seriously affect the patient's quality of life, thus prompting physicians to discuss the symptomatology of the three infarction patterns. We made the following speculations regarding the causal relationship between the infarction pattern and postoperative amnesia. First, postoperative amnesia is most likely caused by an infarction in the territory of the subcallosal artery, particularly in the column of the fornix, a constituent of the Papez neuronal circuit. Second, infarction in the RAH territory alone is unlikely to cause significant amnesia. Third, infarcted foci in the RAH territory, when associated with a subcallosal artery infarction, can cause considerable frontal dysfunction due to impaired frontostriatal circuits in patients with postoperative amnesia, with resultant worsening of the long-term outcome or quality of life.

AB - Well-established studies have shown an elevated level of reactive oxygen species (ROS) that induces oxidative stress in the Alzheimer's disease (AD) patient's brain and an animal model of AD. Herein, we investigated the underlying anti oxidant neuroprotective mechanism of natural dietary supplementation of anthocyanins extracted from Korean black beans in the amyloid precursor protein/presenilin-1 (APP/PS1) mouse model of AD. Both in vivo (APP/PS1 mice) and in vitro (mouse hippocampal HT22 cells) results demonstrated that anthocyanins regulate the phosphorylated-phosphatidylinositol 3-kinase-Akt-glycogen synthase kinase 3 beta (p-PI3K/Akt/GSK3beta) pathways and consequently attenuate amyloid beta oligomer (AbetaO)-induced elevations in ROS level and oxidative stress via stimulating the master endogenous anti-oxidant system of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (Nrf2/HO-1) pathways and prevent apoptosis and neurodegeneration by suppressing the apoptotic and neurodegenerative markers such as activation of caspase-3 and PARP-1 expression as well as the TUNEL and Fluoro-Jade B-positive neuronal cells in the APP/PS1 mice. In vitro ApoTox-GloTM Triplex assay results also showed that anthocyanins act as a potent anti-oxidant neuroprotective agent and reduce AbetaO-induced neurotoxicity in the HT22 cells via PI3K/Akt/Nrf2 signaling. Importantly, anthocyanins improve memory-related pre- and postsynaptic protein markers and memory functions in the APP/PS1 mice. In conclusion, our data suggested that consumption and supplementation of natural-derived anti-oxidant neuroprotective agent such as anthocyanins may be beneficial and suggest new dietary-supplement strategies for intervention in and prevention of progressive neurodegenerative diseases, such as AD. PMID- 29170984 TI - Clinical nutrition and physical rehabilitation in a long-term care setting: preliminary observations in sarcopenic older patients. AB - BACKGROUND: Sarcopenia could have a negative prognostic impact in long-term care residents, which are characterized by multiple comorbidities and a high level of dependence. However, there is limited evidence on its prevalence and management in this healthcare setting. METHODS: All residents living in a long-term care institution were screened for the presence of sarcopenia. Sarcopenic patients in whom functional status could be assessed were included, based on the Tinetti scale (TS) score, in two parallel single-arm trials and received a specific nutritional supplement for muscle mass recovery in combination (TS >= 10) or not (TS < 10) with a supervised physical exercise rehabilitation program for 12 months. The nutritional supplement was administered twice daily for the first 6 months; none for 3 months and again twice daily for the last 3 months. RESULTS: We screened 95 residents and 81 had low skeletal muscle mass (SMM) according to bioimpedance. Thirty-nine residents were included in the intervention phase due to sarcopenia. At 6 months, patients receiving nutritional support alone (n = 17) showed a significant improvement in body weight (P = 0.009) and composition with an increase in SMM (from 15.3 +/- 4.1 to 17.0 +/- 5.1 kg, P = 0.013) and SMM index (SMI; from 6.24 +/- 1.07 to 6.91 +/- 1.54 kg/m2, P = 0.013), but not in handgrip strength (HS). Patients assigned to the multidisciplinary program (n = 22) showed an improvement in both muscle mass [SMM (from 16.6 +/- 6.0 to 17.3 +/- 5.7 Kg, P = 0.050) and SMI (from 6.63 +/- 1.65 to 6.91 +/- 1.52 kg/m2, P = 0.038)] and functional status [HS (from 13.5 +/- 5.0 to 15.6 +/- 6.7; P = 0.028), gait speed (from 0.44 +/- 0.18 to 0.51 +/- 0.20, P = 0.047) and Short Physical Performance Battery (from 4.6 +/- 3.1 to 5.5 +/- 3.2, P = 0.047)] at 6 months. The effect was no longer present after discontinuation of the intervention and was restored after its re-introduction at 12 months. CONCLUSIONS: Nutritional and multidisciplinary interventions tailored on patient's functional status could be considered as strategies for the management of sarcopenia, a high prevalent condition in old adults living in long-term care institutions.

AB - This article considers how seventeenth-century writer John Milton engages in modes of thinking that register the obstetric revolution occurring during the period. During a time when physicians were gaining entry to the birthing room, a medical rhetoric of childbirth was developing that cast childbirth in new pathological terms. Milton's A Masque Presented at Ludlow Castle demonstrates how childbirth was influenced by emerging obstetrical language and practice, as well as the ways in which a writer might question such influence. Finally, this article also draws links between disrupted historical rituals of childbirth and modern anxieties about medically-centred birthing practices.

PMID- 29170989 TI - Modeling energy intake and body weight effects of a long-acting amylin analogue. AB - The inhibitory effect of anti-obesity drugs on energy intake (EI) is counter acted by feedback regulation of the appetite control circuit leading to drug tolerance. This complicates the design and interpretation of EI studies in rodents that are used for anti-obesity drug development. Here, we investigated a synthetic long-acting analogue of the appetite-suppressing peptide hormone amylin (LAMY) in lean and diet-induced obese (DIO) rats. EI and body weight (BW) were measured daily and LAMY concentrations in plasma were assessed using defined time points following subcutaneous administration of the LAMY at different dosing regimens. Overall, 6 pharmacodynamic (PD) studies including a total of 173 rats were considered in this evaluation. Treatment caused a dose-dependent reduction in EI and BW, although multiple dosing indicated the development of tolerance over time. This behavior could be adequately described by a population model including homeostatic feedback of EI and a turnover model describing the relationship between EI and BW. The model was evaluated by testing its ability to predict BW loss in a toxicology study and was utilized to improve the understanding of dosing regimens for obesity therapy. As such, the model proved to be a valuable tool for the design and interpretation of rodent studies used in anti-obesity drug development. PMID- 29170990 TI - Lack of ethnic differences of moxifloxacin and metabolite pharmacokinetics in East Asian men. AB - This study was designed to investigate ethnic differences in the pharmacokinetics (PKs) of moxifloxacin and its metabolites, M1 (sulfo conjugate) and M2 (acyl glucuronate), among Japanese, Chinese, and Korean populations, following oral administration. We used a population PK modeling approach using data from a clinical study involving 79 healthy male volunteers. A comprehensive population PK model considering the PK mechanism of moxifloxacin and its metabolites was newly built. The structures of the final model were two-compartment for moxifloxacin and one-compartment for M1 and M2, with first-order absorption with lag time for all three compounds. The formation of M1 and M2 from moxifloxacin via a first-pass effect and subsequent metabolic clearance in the system were also modeled. Lean body mass on the central volume of distribution (V c ) and estimated glomerular filtration rate on renal clearance (CL r ) were identified as covariates of PKs of moxifloxacin. Additionally, bioavailability was slightly higher in Koreans, whereas CL r , non-renal clearance (CL nr ), and V c were slightly lower. Regarding M1 and M2, body surface area on CL r of M2 and UGT1A1*6 on F of M2 were modeled. Korean ethnicity was observed to influence CL nr of M2, F of M2, and the metabolic clearance of moxifloxacin to M2. However, the exposure levels of moxifloxacin, M1, and M2 in Koreans were comparable to those in Japanese and Chinese because the effects of Korean ethnicity on some PK parameters were counterbalanced. These results suggest that PKs for moxifloxacin and its metabolites among East Asian populations are essentially similar. PMID- 29170991 TI - Facilitated enumeration of the silicate bacterium Paenibacillus mucilaginosus comb. nov. (formerly Bacillus mucilaginosus) via tetrazolium chloride incorporation into a double agar-based solid growth medium. AB - Accurate enumeration of Paenibacillus mucilaginosus (formerly Bacillus mucilaginosus) bacterium from environmental samples on solid medium is challenging owing to its extensive extracellular polysaccharides (EPS) excretion. In the present study, P. mucilaginosus enumeration has been facilitated by a simple modification: addition of triphenyl tetrazolium chloride (TTC) to growth medium and application of a second soft agar layer. Results show distinctively better and accurate colonies' count. This method can be applied to all bacterial species that produce excessive EPS that may interfere with direct count. PMID- 29170992 TI - Clinical strains of Lactobacillus reduce the filamentation of Candida albicans and protect Galleria mellonella against experimental candidiasis. AB - Candida albicans is the most common human fungal pathogen and can grow as yeast or filaments, depending on the environmental conditions. The filamentous form is of particular interest because it can play a direct role in adherence and pathogenicity. Therefore, the purpose of this study was to evaluate the effects of three clinical strains of Lactobacillus on C. albicans filamentation as well as their probiotic potential in pathogen-host interactions via an experimental candidiasis model study in Galleria mellonella. We used the reference strain Candida albicans ATCC 18804 and three clinical strains of Lactobacillus: L. rhamnosus strain 5.2, L. paracasei strain 20.3, and L. fermentum strain 20.4. First, the capacity of C. albicans to form hyphae was tested in vitro through association with the Lactobacillus strains. After that, we verified the ability of these strains to attenuate experimental candidiasis in a Galleria mellonella model through a survival curve assay. Regarding the filamentation assay, a significant reduction in hyphae formation of up to 57% was observed when C. albicans was incubated in the presence of the Lactobacillus strains, compared to a control group composed of only C. albicans. In addition, when the larvae were pretreated with Lactobacillus spp. prior to C. albicans infection, the survival rate of G. mellonela increased in all experimental groups. We concluded that Lactobacillus influences the growth and expression C. albicans virulence factors, which may interfere with the pathogenicity of these microorganisms.

PMID- 29170994 TI - "No go" donor hepatectomy in living-donor liver transplantation. AB - BACKGROUND: Selection of appropriate donors after rigorous evaluation is of paramount importance in living-donor liver transplantation. Despite this, donor surgery may not proceed due to unforeseen reasons. The aim of this paper is to study reasons for "no go" donor hepatectomy in living liver donors. PATIENTS AND METHODS: Donor operations stopped after surgical start, directly due to donor safety-related reasons, qualified for inclusion as "no go" donor hepatectomy. Living-donor evaluation was performed as per standard protocol. Data for consecutive living liver donors operated between April 2012 and November 2016 were analyzed to evaluate reasons for "no go" donor hepatectomy in a liver transplantation unit at a tertiary care teaching hospital. RESULTS: In 307 donors, the operation was aborted in 7 (2.3 %). One patient had unexpected biliary pathology with fibrosis found intraoperatively. Operations in five donors were abandoned in view of liver parenchymal abnormalities (fibrosis/steatohepatitis). One donor had hemodynamically significant bradycardia after handling the round ligament. All these donors recovered uneventfully and remained well on follow-up. CONCLUSIONS: "No go" donor hepatectomy remains a real possibility despite rigorous assessment. Although thresholds for on-table rejection of the donor after complete evaluation vary, "no go" hepatectomy is a calculated risk-avoidance approach.

AB - Despite the importance of the nursing profession for healthcare delivery, costs, and quality, there is relatively little research on how provider payments to hospitals affect the labor market for nurses. This study deals with the hospital wage index (HWI) adjustment to Medicare hospital payments, an area-level adjustment intended to compensate hospitals in high-cost labor markets. Since the HWI adjustment is based on hospital-reported labor costs, some argue that it incentivizes hospitals in concentrated markets to pay higher wages to nurses and other workers (the "circularity" critique). We investigate this critique using market-level data on the relative wages reported by nurses and hospital-level data on the average hourly wage for healthcare workers. For identification, we exploit a 2005 change in the geographic area used to define labor markets, which resulted in exogenous changes in the ability of some hospitals to influence their area's wage index. We find that worker-reported relative nurse wages and hospital reported healthcare worker wages are higher in some locations where hospitals experienced increased opportunities to game the circularity of the wage index, but these effects appear to be driven by pre-existing wage growth. Medicare's HWI adjustment method does not appear to suffer from inefficiency due to circularity. PMID- 29170997 TI - Differential Expression of Ion Channels in Adult and Neonatal Rat Ventral Respiratory Column. AB - In mammals, the neural control of breathing is attributed to circuits distributed along the ventral respiratory column (VRC) in the ventrolateral medulla. The VRC contains the kernel for generation of the inspiratory phase of respiratory rhythm and nuclei involved in central chemoreception. During development, the respiratory rhythm, as well as central chemosensitivity, adjusts to meet the changing physiological requirements associated with increased body weight and size. Gene expression in VRC ontogeny is well characterized. However, little is known about gene expression in the VRC during postnatal development. Here, we sought to characterize the changes in gene expression that occur in the VRC of the adult rat (5-6 months of age) in comparison with the VRC of neonate rat (1-4 days old). We isolated total RNA from VRC tissue punches collected from thick transversal slices. We hybridized cDNA to a 5000-oligonucleotide rat microarray. We found that 218 genes (4.4%) of the 5000 genes in the microarray changed their expression in adult VRC with respect to that from neonate. To further analyze the modified expression of specific genes, we quantified the differential expression of 84 genes of neuronal ion channels using a quantitative RT-PCR array. This analysis confirmed the overexpression of 68 genes and the underexpression of 14 genes in the VRC from adult compared with that from neonate. Our findings may help to explain the functional changes in respiratory rhythm and chemosensitivity occurring throughout life. PMID- 29170999 TI - The Baby Boom and later life: is critical care fit for the future? AB - Populations around the world are ageing while in many developed countries the proportion of elderly patients admitted to critical care is rising. It is clear that age alone should not be used as a reason for refusing intensive care admission. Critical care in this patient group is challenging in many ways: with advancing age, several physiological changes occur which all lead to a subsequent reduction of physical performance and compensatory capacity, in many cases additionally aggravated by chronic illness. Subsequently, these age-dependent changes (with or without chronic illness) increase the risk for death, treatment costs and a prolonged length of intensive care and hospital stay. This review explores the potential of using co-morbidity and frailty to predict outcome and to help to make better decisions about critical care admission in the elderly. The authors explore the challenges of using different frailty assessment tools and offer a model for holistic approach to answer these questions. PMID- 29170998 TI - Introducing TOPMAST, the first double-blind randomized clinical trial specifically dedicated to perioperative maintenance fluid therapy in adults. AB - BACKGROUND: Although prescribed to every patient undergoing surgery, maintenance fluid therapy is a poorly researched part of perioperative fluid therapy. The tonicity of the chosen solutions, could be an important cause of morbidity, with hyponatremia being a potential side effect of hypotonic solutions, where isotonic solution could lead to fluid overload. METHODS: The TOPMAST-trial is an ongoing prospective single-center double-blind randomized trial comparing an isotonic and a hypotonic maintenance fluid strategy during and after surgery in patients undergoing different types of major thoracic surgery. Patients receive NaCl 0.9% in glucose 5% with an added 40 mmol L-1 of potassium chloride or a premixed solution containing 54 mmol L-1 sodium, 55 mmol L-1 chloride and 26 mmol of potassium at a rate of 27 mL per kg of body weight per day. The primary hypothesis is that isotonic maintenance solutions cause a more positive perioperative fluid balance than hypotonic fluids. Different secondary safety endpoints will be explored, especially the effect of the study treatments on the occurrence electrolyte disturbances (e.g. hyponatremia, hyperchloremia) and a set of clinical endpoints. Efficacy endpoints include the need for resuscitation fluids and assessment of renal and hormonal adaptive mechanisms. An anticipated 68 patients will be included between March 2017 and January 2018. DISCUSSION: The study will provide the most comprehensive evaluation of clinically important outcomes associated with the choice of perioperative maintenance fluid therapy. PMID- 29171000 TI - Applying pharmacokinetic/pharmacodynamic principles for optimizing antimicrobial therapy during continuous renal replacement therapy AB - Continuous renal replacement therapy (CRRT) is progressively supplanting intermittent haemodialysis (IHD) in critically ill patients. Although CRRT indeed offers more appropriate haemodynamic, fluid, and metabolic stability, concern is rising about its impact on concomitant drugs and, in particular, antimicrobial treatment. Antimicrobial dose recommendations have been elaborated to avoid drug accumulation and toxicity in patients undergoing IHD. However, these dosing regimens have resulted in significant underdosing in patients undergoing CRRT, thereby increasing the risk of treatment failure and development of resistance. Applying pharmacokinetic/pharmacodynamic (PK/PD) principles may aid one to obtain more adequate antimicrobial therapy during CRRT. Much progress has been made in recent years resulting in relevant changes in particular antimicrobial therapies. In this review, we discuss antimicrobials that are frequently used in an intensive care setting. Drugs are divided according to their PK/PD characteristics and, wherever possible, dose recommendations during CRRT are provided. Of course, while therapeutic drug monitoring remains the best way to cope with PK/PD variability within a critically ill CRRT population, its bedside use is actually limited to some specific antibiotics. PMID- 29171001 TI - Modern imaging techniques in intra-abdominal hypertension and abdominal compartment syndrome: a bench to bedside overview. AB - Intra-abdominal hypertension (IAH) is common in critically ill patients. Diagnosis is based on measurement of intraabdominal pressure, most commonly via the bladder. Modern imaging techniques with plain radiographs, computed tomography and magnetic resonance can help establish the diagnosis and also guide treatment. In 2013 the Abdominal Compartment Society (WSACS) published updated consensus definitions and recommendations for management of IAH and abdominal compartment syndrome (ACS). This review will give a concise overview of the important role radiographic imaging plays within these management guidelines. PMID- 29171002 TI - Pharmacokinetic/pharmacodynamic analysis of adjunctive perampanel in subjects with partial-onset seizures. AB - OBJECTIVES: Explore perampanel pharmacokinetics (PK) in all subjects (aged >=12 years) vs adolescents (aged >=12 to <=17 years) with partial-onset seizures (POS) and identify factors explaining between-subject variability in efficacy using a population PK/pharmacodynamic (PD) analysis. MATERIALS & METHODS: Population PK analysis was performed using nonlinear mixed-effect modeling with data from phase II/III randomized, double-blind, placebo-controlled studies of adjunctive perampanel in POS. Perampanel exposure was predicted for all subjects and adolescents. Population PK/PD analyses were performed using data from phase III studies to explore the relationship between perampanel exposure and 28-day average seizure frequency and responder probability. RESULTS: Pooled perampanel PK data from 1318 subjects were described by a one-compartment disposition model. In the absence of antiepileptic drugs (AEDs) affecting perampanel PK, estimated perampanel apparent clearance (CL/F) was 0.668 L/h (all subjects) and 0.682 L/h (adolescent subjects). Co-administration of carbamazepine and oxcarbazepine/phenytoin reduced perampanel exposure. Gender, Asian race (excluding Japanese or Chinese), and increasing alanine aminotransferase lowered perampanel CL/F, but differences were small and not considered clinically relevant. Adolescent outcomes were similar to the total population. Based on PK/PD data from 1748 subjects, percent reduction in 28-day average seizure frequency from baseline and responder probability increased with increasing perampanel exposure; concomitant CYP3A-inducing AEDs lowered perampanel exposure but did not impact the slope for responder probability. CONCLUSIONS: These results are consistent with previous analyses but expand on these through inclusion of a larger number of patients from different ethnic groups, and demonstrate that outcomes were similar between adults and adolescents.

AB - Several CAR T designs with CD19 specificity have been associated with consistent responses in clinical trials with complete remission (CR) rates ranging from 70 90%. Relevant challenges remain to be addressed, such as production time, early loss of CAR T cells, relapse due to loss of the target antigen, and prevention of severe cytokine release syndrome and neurotoxicity. This review describes constructs, clinical trial results, side effects, and future direction of CAR T cell therapy in B-ALL. PMID- 29171003 TI - Inhibition of monoacylglycerol lipase terminates diazepam-resistant status epilepticus in mice and its effects are potentiated by a ketogenic diet. AB - OBJECTIVE: Status epilepticus (SE) is a life-threatening and commonly drug refractory condition. Novel therapies are needed to rapidly terminate seizures to prevent mortality and morbidity. Monoacylglycerol lipase (MAGL) is the key enzyme responsible for the hydrolysis of the endocannabinoid 2-arachidonoylglycerol (2 AG) and a major contributor to the brain pool of arachidonic acid (AA). Inhibiting of monoacylglycerol lipase modulates synaptic activity and neuroinflammation, 2 mediators of excessive neuronal activation underlying seizures. We studied the effect of a potent and selective irreversible MAGL inhibitor, CPD-4645, on SE that was refractory to diazepam, its neuropathologic sequelae, and the mechanism underlying the drug's effects. METHODS: Diazepam resistant SE was induced in adult mice fed with standard or ketogenic diet or in cannabinoid receptor type 1 (CB1) receptor knock-out mice. CPD-4645 (10 mg/kg, subcutaneously) or vehicle was dosed 1 and 7 h after status epilepticus onset in video-electroencephalography (EEG) recorded mice. At the end of SE, mice were examined in the novel object recognition test followed by neuronal cellloss analysis. RESULTS: CPD-4645 maximal plasma and brain concentrations were attained 0.5 h postinjection (half-life = 3.7 h) and elevated brain 2-AG levels by approximately 4-fold. CPD-4645 administered to standard diet-fed mice progressively reduced spike frequency during 3 h postinjection, thereby shortening SE duration by 47%. The drug immediately abrogated SE in ketogenic diet-fed mice. CPD-4645 rescued neuronal cell loss and cognitive deficit and reduced interleukin (IL)-1beta and cyclooxygenase 2 (COX-2) brain expression resulting from SE. The CPD-4645 effect on SE was similar in mice lacking CB1 receptors. SIGNIFICANCE: MAGL represents a novel therapeutic target for treating status epilepticus and improving its sequelae. CPD-4645 therapeutic effects appear to be predominantly mediated by modulation of neuroinflammation. PMID- 29171005 TI - Is There a Downside to Anticipating the Upside? Children's and Adults' Reasoning About How Prior Expectations Shape Future Emotions. AB - Four- to 10-year-olds and adults (N = 205) responded to vignettes involving three individuals with different expectations (high, low, and no) for a future event. Participants judged characters' pre-outcome emotions, as well as predicted and explained their feelings following three events (positive, attenuated, and negative). Although adults rated high-expectation characters more negatively than low-expectation characters after all outcomes, children shared this intuition starting at 6-7 years for negative outcomes, 8-10 years for attenuated, and never for positive. Comparison to baseline (no expectation) indicated that understanding the costs of high expectations emerges first and remains more robust across age than recognition that low expectations carry benefits. Explanation analyses further clarified this developing awareness about the relation between thoughts and emotions over time. PMID- 29171007 TI - High-Ability Grouping: Benefits for Gifted Students' Achievement Development Without Costs in Academic Self-Concept. AB - Effects of full-time ability grouping on students' academic self-concept (ASC) and mathematics achievement were investigated in the first 3 years of secondary school (four waves of measurement; students' average age at first wave: 10.5 years). Students were primarily from middle and upper class families living in southern Germany. The study sample comprised 148 (60% male) students from 14 gifted classes and 148 (57% male) students from 25 regular classes (matched by propensity score matching). Data analyses involved multilevel and latent growth curve analyses. Findings revealed no evidence for contrast effects of class average achievement or assimilation effects of class type on students' ASC. ASC remained stable over time. Students in gifted classes showed higher achievement gains than students in regular classes. PMID- 29171006 TI - BAD knockout provides metabolic seizure resistance in a genetic model of epilepsy with sudden unexplained death in epilepsy. AB - Metabolic alteration, either through the ketogenic diet (KD) or by genetic alteration of the BAD protein, can produce seizure protection in acute chemoconvulsant models of epilepsy. To assess the seizure-protective role of knocking out (KO) the Bad gene in a chronic epilepsy model, we used the Kcna1-/- model of epilepsy, which displays progressively increased seizure severity and recapitulates the early death seen in sudden unexplained death in epilepsy (SUDEP). Beginning on postnatal day 24 (P24), we continuously video monitored Kcna1-/- and Kcna1-/- Bad-/- double knockout mice to assess survival and seizure severity. We found that Kcna1-/- Bad-/- mice outlived Kcna1-/- mice by approximately 2 weeks. Kcna1-/- Bad-/- mice also spent significantly less time in seizure than Kcna1-/- mice on P24 and the day of death, showing that BadKO provides seizure resistance in a genetic model of chronic epilepsy. PMID- 29171008 TI - Patient-reported outcome measures for young people with developmental disabilities: incorporation of design features to reduce cognitive demands. AB - : Use of patient-reported outcome measures (PROMs) may increase the involvement of young people with developmental disabilities in their healthcare decisions and healthcare-related research. Young people with developmental disabilities may have difficulty completing PROMs because of extraneous assessment demands that require additional cognitive processes. However, PROM design features may mitigate the impact of these demands. We identified and evaluated six pediatric PROMs of self-care and domestic life tasks for the incorporation of suggested design features that can reduce cognitive demands. PROMs incorporated an average of 6 out of 11 content, 7 out of 14 layout, and 2 out of 9 administration features. This critical review identified two primary gaps in PROM design: (1) examples and visuals were not optimized to reduce cognitive demands; and (2) administration features that support young people's motivation and self-efficacy and reduce frustration were underutilized. Because assessment demands impact the validity of PROMs, clinicians should prospectively consider the impact of these demands when selecting PROMs and interpreting scores. WHAT THIS PAPER ADDS: Patient-reported outcome measure (PROM) design features can reduce assessment demands related to cognitive processes. Pediatric PROMs underutilize design features that decrease cognitive demands of self-reporting. PMID- 29171009 TI - Bevacizumab in combination with different platinum-based doublets in the first line treatment for advanced nonsquamous non-small-cell lung cancer: A network meta-analysis. AB - Platinum-based doublet chemotherapy with or without bevacizumab is the standard treatment for untreated advanced nonsquamous non-small-cell lung cancer (NS NSCLC). However, adding bevacizumab to chemotherapies other than paclitaxel carboplatin is, though widely applied clinically, largely unjustified due to the lack of head-to-head data. We performed a Bayesian network meta-analysis (NMA) to address this important issue. Data of 8,548 patients from 18 randomized controlled trials (RCTs) receiving six treatments, including taxane-platinum (Taxane-Pt), gemcitabine-platinum (Gem-Pt), pemetrexed-platinum (Pem-Pt), taxane platinum + bevacizumab (Taxane-Pt + B), gemcitabine-platinum + bevacizumab (Gem Pt + B) and pemetrexed-platinum + bevacizumab (Pem-Pt + B), were incorporated into the analyses. Direct and indirect evidence of overall survival (OS) and progression-free survival (PFS) were synthesized at the hazard ratio (HR) scale and evidence of objective response rate (ORR) and serious adverse events (SAE) were synthesized at the odds ratio (OR) scale. Taxane-Pt + B showed significant advantages in OS (HR = 0.79, p < 0.001), PFS (HR = 0.54, p < 0.001) and ORR (OR = 2.7, p < 0.001) over Taxane-Pt with comparable tolerability (OR = 3.1, p = 0.08). Gem-Pt + B showed no OS benefit compared to any other treatment. No significant differences were detected between Pem-Pt + B and Pem-Pt in four outcomes. In terms of the benefit-risk ratio, Pem-Pt and Taxane-Pt + B were ranked the first and second, respectively. In conclusion, in the first-line treatment for advanced NS-NSCLC, Taxane-Pt and Gem-Pt are the most and least preferable regimens to be used with bevacizumab, respectively. Adding bevacizumab to Pem-Pt remains unjustified because it fails to improve efficacy or tolerability. In terms of the benefit-risk ratio, Pem-Pt and Taxane-Pt + B are the best and second-best treatment for this population. PMID- 29171010 TI - Prenatal exposure to ketamine in rats: Implications on animal models of schizophrenia. AB - Schizophrenia is a complex neuropsychiatric disorder characterized by hallucinations, delusions, anhedonia, flat affect and cognitive impairments. The aim of this study was to propose a prenatal treatment with ketamine, a psychedelic drug that acts as a non-competitive inhibitor of glutamate NMDA receptors, as a neurodevelopmental animal model of schizophrenia. The drug was applied (i.m. 60 mg.kg-1 h-1 ) in pregnant Sprague-Dawley rats on gestational Day 14. Offspring behavior was studied on pubertal (4 weeks old) and adult (10 weeks old) stages. Also, hippocampal CA1-CA3 morphology was assessed in adult animals through a Nissl stain. Results showed a disinhibition and hyperactive behavior in pubertal animals exposed to ketamine, followed in adulthood with cognitive impairments, social withdrawal, anxiety, depression, and aggressive like behaviors. In the hippocampus, a reduction of the CA3 layer thickness was observed, without changes in cell density. These results strongly suggest a robust link between prenatal pharmacologic manipulation of NMDA receptors and schizophrenia. PMID- 29171011 TI - Stroke-like migraine attacks after radiation therapy: A misnomer? AB - OBJECTIVE: To understand the frequency of electrographic and clinical seizures in patients with stroke-like migraine attacks after radiation therapy (SMART), and determine whether SMART warrants comprehensive electroencephalographic (EEG) monitoring and aggressive seizure management. METHODS: We searched our magnetic resonance brain imaging report database for all patients between January 2013 and December 2015 for suspected SMART syndrome. Clinical inclusion criteria were further applied as follows: inpatient adults (>18 years of age) with history of cranial radiation presenting with acute neurologic deficits as primary admission reason who lacked evidence of recurrent or new brain malignancy, stroke, or infectious agents in cerebrospinal fluid. Six patients were identified. All 6 patients underwent prolonged video EEG monitoring as part of our standard protocol. RESULTS: All patients but 1 were found to have multiple or prolonged electrographic seizures consistent with status epilepticus during video EEG monitoring. Their neurological deficit and/or mental status change improved in parallel with resolution of the seizure activity. SIGNIFICANCE: SMART is likely a misnomer that underestimates the significance of seizures and status epilepticus in the pathophysiology and clinical presentation of the syndrome. Systematic continuous EEG monitoring and appropriate seizure management is warranted to reduce symptom duration and optimize clinical outcome. PMID- 29171012 TI - Children's anxiety symptoms and salivary immunoglobulin A: A mutual regulatory system? AB - Anxiety can impact the immune system resulting in negative health outcomes. Salivary immunoglobulin A (sIgA) is a first line of defense against foreign antigens, with lowered levels indicative of weakened mucosal immunity. Little is known about how anxiety symptoms affect the diurnal rhythm of sIgA secretion, or the longitudinal transactional sequence between the two in children and adolescents. The goals of the two studies were to: (i) explore the concurrent associations between self-reported anxiety symptoms and diurnal variations of sIgA across the day using repeated daily samples of sIgA; and (ii) examine transactional relations between children's anxiety and aggregated total amount of sIgA levels across successive periods from middle childhood (Wave 1; ages 9-12) to early adolescence (Wave 2; ages 12-15), and from early to mid- adolescence (Wave 3; ages 15-18). Concurrent results showed a steeper (positive) rise in diurnal slope of sIgA from awakening to 5 hr post-awakening in children with higher anxiety. Longitudinally, higher levels of total anxiety, and specifically, worries at Wave 1 significantly predicted lower cumulative daily levels of sIgA 3 years later at Wave 2. Lowered sIgA levels at Wave 2 in turn predicted higher anxiety at Wave 3, illustrating a "vicious cycle" feedback loop. These findings broaden our understanding of the developmental links between anxiety symptoms, the immune system, and health. PMID- 29171013 TI - Severe infantile onset developmental and epileptic encephalopathy caused by mutations in autophagy gene WDR45. AB - Heterozygous de novo variants in the autophagy gene, WDR45, are found in beta propeller protein-associated neurodegeneration (BPAN). BPAN is characterized by adolescent onset dementia and dystonia; 66% patients have seizures. We asked whether WDR45 was associated with developmental and epileptic encephalopathy (DEE). We performed next generation sequencing of WDR45 in 655 patients with developmental and epileptic encephalopathies. We identified 3/655 patients with DEE plus 4 additional patients with de novo WDR45 pathogenic variants (6 truncations, 1 missense); all were female. Six presented with DEE and 1 with early onset focal seizures and profound regression. Median seizure onset was 12 months, 6 had multiple seizure types, and 5/7 had focal seizures. Three patients had magnetic resonance susceptibility-weighted imaging; blooming was noted in the globus pallidi and substantia nigra in the 2 older children aged 4 and 9 years, consistent with iron accumulation. We show that de novo pathogenic variants are associated with a range of developmental and epileptic encephalopathies with profound developmental consequences. PMID- 29171015 TI - Dental health-care service utilisation and its determinants in West Iran: a cross sectional study. AB - BACKGROUND: Dental health care is not only an effective strategy for the prevention, early diagnosis and treatment of oral diseases but also contributes to the general health of communities. This study aimed to investigate the situation of dental health-care service utilisation and its determinants in Kermanshah city, western Iran, in 2015. METHODS AND MATERIALS: A cross-sectional study on a total of 894 household heads was conducted. The participants were selected using a multistage sampling technique. A self-administered questionnaire was used to collect the data. Multiple logistic regression was performed to assess factors associated with utilisation of dental-care services and a negative binomial regression was carried out to identify the main factor associated with the frequency of visiting a dentist for dental health care. A statistically significant association was considered at a value of P < 0.05. All the analyses were performed using STATA version 12. FINDING: Of the total household heads who participated in the study, 60.3% and 9.9% reported visiting a dentist for dental treatment in the past year and for 6-monthly dental check-ups, respectively. The average +/- standard deviation number of visits by a respondent was 2.08 +/- 2.97. Of the total number of respondents, 281 (31.4%) reported visiting a dentist once or twice in the last 12 months for dental health-care services, while 28.9% reported visiting a dentist more than twice in the same time period. Ageing, having dental insurance, higher income, being a university graduate, self-rated poor oral health and not regularly brushing own teeth were the main factors associated with utilisation of dental health-care services. CONCLUSION: Our study indicates that dental health-care utilisation among households in the study area was influenced by a number of factors, including being socio-economically disadvantaged, self-rated poor oral health and not regularly brushing own teeth. Therefore, in this setting, dental-intervention programmes, including dental health insurance, should focus on mechanisms that can strengthen utilisation of preventive dental health-care services among disadvantaged households. PMID- 29171014 TI - The Influence of Big (Clinical) Data and Genomics on Precision Medicine and Drug Development. AB - Drug development continues to be costly and slow, with medications failing due to lack of efficacy or presence of toxicity. The promise of pharmacogenomic discovery includes tailoring therapeutics based on an individual's genetic makeup, rational drug development, and repurposing medications. Rapid growth of large research cohorts, linked to electronic health record (EHR) data, fuels discovery of new genetic variants predicting drug action, supports Mendelian randomization experiments to show drug efficacy, and suggests new indications for existing medications. New biomedical informatics and machine-learning approaches advance the ability to interpret clinical information, enabling identification of complex phenotypes and subpopulations of patients. We review the recent history of use of "big data" from EHR-based cohorts and biobanks supporting these activities. Future studies using EHR data, other information sources, and new methods will promote a foundation for discovery to more rapidly advance precision medicine. PMID- 29171016 TI - Long-term development of gait after multilevel surgery in children with cerebral palsy: a multicentre cohort study. AB - AIM: We investigated the long-term efficacy and safety of multilevel surgery (MLS) in ambulatory children with bilateral spastic cerebral palsy (CP). METHOD: Two hundred and thirty-one children were evaluated at short term (1.1y, SD 0.4) and long term (9.1y, SD 3.0) follow-up using clinical examination and gait analysis. MLS was investigated by studying changes in the Gait Profile Score (GPS) referenced to the minimally important clinical difference. RESULTS: Ambulatory children aged 10 years and 7 months (SD 2y 11mo) at MLS in Gross Motor Function Classification System levels I (19), II (144), and III (68) showed a decrease (improvement) in preoperative GPS from 16.3 degrees (SD 4.8) to 11.3 degrees (SD 3.2) at short-term follow-up, an improvement of 5 degrees . At long term follow-up, GPS was maintained at 11.4 degrees (SD 3.1). Overall, 177 (76.6%) children maintained their improvement in GPS after 9 years. INTERPRETATION: Multilevel surgery is a safe and effective surgical intervention, which leads to a significant improvement in gait kinematics in children with bilateral spastic CP. This study improves our understanding of MLS in the long term and will help to inform families and children when planning for MLS. WHAT THIS PAPER ADDS: Largest study of multilevel surgery (MLS) for children with bilateral spastic cerebral palsy, with longest follow-up. MLS resulted in significant long-term improvements in gait function. Minor adverse events were common, while events requiring intervention were uncommon (4% of children). Thirty-nine per cent of children required additional surgery during follow-up. 'Single-event multilevel surgery' was changed to the more realistic term 'multilevel surgery'. PMID- 29171017 TI - Pathogenesis and therapeutic targeting of aberrant MYC expression in haematological cancers. AB - Identifying and therapeutically targeting cancer cell liabilities is of utmost importance in order to improve the treatment of patients with malignancies of poor prognosis. The MYC family genes (MYC, MYCN and MYCL) are among the most deregulated proto-oncogenes in human cancer. Aberrant MYC expression is frequently associated with poor prognosis. Although many aspects of MYC-mediated tumour biology are well characterized, there are currently no effective means for targeting MYC in a specific manner that have been established for clinical use. This review first discusses the role of MYC in the pathogenesis of haematopoietic malignancies, and secondly summarizes how insight into MYC functions could be translated into therapeutic approaches. In particular, we will address the possibilities of taking advantage of MYC-induced cancer cell vulnerabilities that could be exploited in terms of synthetic lethal interactions. PMID- 29171018 TI - Personal history of non-melanoma skin cancer diagnosis and death from melanoma in women. AB - Melanoma incidence is increasing. We evaluated risk of melanoma death after diagnosis of non-melanoma skin cancer (NMSC). We followed 77,288 female American nurses from the Nurses' Health Study from 1986 to 2012. We used Cox proportional hazards models to determine the hazard ratio (HR) of lethal and non-lethal melanoma diagnosis and melanoma death, according to personal NMSC history. Among melanoma cases, we examined the HR of melanoma death and the odds ratio (OR) of melanoma with a Breslow thickness >=0.8 mm or Clark's levels of IV and V according to history of NMSC. We documented 930 melanoma cases without NMSC history and 615 melanoma cases with NMSC history over 1.8 million person-years. The multivariate-adjusted HR (95% confidence interval) of melanoma death associated with personal history of NMSC was 2.89 (1.85-4.50). Women with history of NMSC were more likely to develop non-lethal melanoma than lethal melanoma (HR (95% CI): 2.31 (2.05-2.60) vs. 1.74 (1.05-2.87)). Among melanoma cases, women with history of NMSC had a non-significant decreased risk of melanoma deaths (0.87 (0.55-1.37)), Breslow thickness >=0.8 mm (0.85 (0.59-1.21)) and Clark's levels IV and V (0.81(0.52-1.24)). Women with NMSC history were less likely to be diagnosed with a lethal melanoma than a non-lethal melanoma, but overall rate of melanoma diagnosis was increased in both subtypes, leading to the increased risk of melanoma death. Our findings suggest the continued need for dermatologic screening for patients after NMSC diagnosis, given increased melanoma risk. Early detection among NMSC patients may decrease deaths from melanoma. PMID- 29171019 TI - Cortisol profiles differentiated in adolescents and young adult males with fragile X syndrome versus autism spectrum disorder. AB - BACKGROUND: Fragile X syndrome (FXS) and non-syndromic autism spectrum disorder (ASD) are distinct disorders with overlapping behavioral features. Both disorders are also highly associated with anxiety with abnormal physiological regulation implied mechanistically. Some reports suggest atypical hypothalamus-pituitary adrenal (HPA) axis function, indexed via aberrant cortisol reactivity, in both FXS and non-syndromic ASD. However, no study has compared cortisol reactivity across these two disorders, or its relationship to ASD symptom severity. METHODS: Cortisol reactivity (prior to and following a day of assessments) was measured in 54 adolescent/young adult males with FXS contrasted to 15 males with non syndromic ASD who had low cognitive abilities. RESULTS: Greater ASD symptom severity was related to increased cortisol reactivity and higher levels at the end of the day, but only in the non-syndromic ASD group. Elevated anxiety was associated with increased HPA activation in the group with FXS alone. CONCLUSIONS: Taken together, findings suggest a unique neuroendocrine profile that distinguishes adolescent/young adult males with FXS from those with non syndromic ASD. Severity of ASD symptoms appears to be related to cortisol reactivity in the non-syndromic ASD sample, but not in FXS; while anxiety symptoms are associated with HPA activation in the FXS sample, but not in ASD despite a high prevalence of ASD, anxiety and physiological dysregulation characteristic in both populations.

PMID- 29171020 TI - Clopidogrel but Not Prasugrel Significantly Inhibits the CYP2C8-Mediated Metabolism of Montelukast in Humans. AB - The oxidation of montelukast is mainly mediated by cytochrome P450 (CYP) 2C8, but other mechanisms may contribute to its disposition. In healthy volunteers, we investigated the effects of two widely used P2Y12 inhibitors on montelukast pharmacokinetics. Clopidogrel (300 mg on day 1 and 75 mg on day 2) increased the area under the plasma concentration-time curve (AUC) of montelukast 2.0-fold (90% confidence interval (CI) 1.72-2.28, P < 0.001) and decreased the M6:montelukast AUC0-7h ratio to 45% of control (90% CI 40-50%, P < 0.001). Prasugrel (60 mg on day 1 and 10 mg on day 2) had no clinically meaningful effect on montelukast pharmacokinetics. Our results imply that clopidogrel is at least a moderate inhibitor of CYP2C8, but prasugrel is not a clinically relevant CYP2C8 inhibitor. The different interaction potentials of clopidogrel and prasugrel are important to consider when antiplatelet therapy is planned for patients at risk for polypharmacy with CYP2C8 substrates. PMID- 29171023 TI - Thinking fast and slow - in clinical psychiatry. PMID- 29171021 TI - Xenopus-derived glucagon-like peptide-1 and polyethylene-glycosylated glucagon like peptide-1 receptor agonists: long-acting hypoglycaemic and insulinotropic activities with potential therapeutic utilities. AB - BACKGROUND AND PURPOSE: Incretin-based therapies based on glucagon-like peptide-1 (GLP-1) receptor agonists are effective treatments of type 2 diabetes. Abundant research has focused on the development of long-acting GLP-1 receptor agonists. However, all GLP-1 receptor agonists in clinical use or development are based on human or Gila GLP-1. We have identified a potent GLP-1 receptor agonist, xGLP-1B, based on Xenopus GLP-1. EXPERIMENTAL APPROACH: To further modify the structure of xGLP-1B, alanine scanning was performed to study the structure -activity relationship of xGLP-1B. Two strategies were then employed to improve bioactivity. First, the C-terminal tail of lixisenatide was appended to cysteine altered xGLP-1B analogues. Second, polyethylene glycol (PEG) chains with different molecular weights were conjugated with the peptides, giving a series of PEGylated conjugates. Comprehensive bioactivity studies of these conjugates were performed in vitro and in vivo. RESULTS: From the in vitro receptor activation potency and in vivo acute hypoglycaemic activities of conjugates 25 -36, 33 was identified as the best candidate for further biological assessments. Conjugate 33 exhibited prominent hypoglycaemic and insulinotropic activities, as well as improved pharmacokinetic profiles in vivo. The prolonged antidiabetic duration of 33 was further confirmed by pre-oral glucose tolerance tests (OGTT) and multiple OGTT. Furthermore, chronic treatment of db/db mice with 33 ameliorated non fasting blood glucose and insulin levels, reduced HbA1c values and normalized their impaired glucose tolerance. Importantly, no in vivo toxicity was observed in mice treated with 33. CONCLUSIONS AND IMPLICATIONS: Peptide 33 is a promising long-acting type 2 diabetes therapeutic deserving further investigation. PMID- 29171024 TI - miR-19b-3p induces cell proliferation and reduces heterochromatin-mediated senescence through PLZF in goat male germline stem cells. AB - Promyelocytic leukemia zinc finger PLZF, known as ZBTB16 or ZFP145 is a critical zinc finger protein of male germline stem cells (mGSCs), it's an essential transcriptional factor for goat testis development and spermatogenesis. Loss of PLZF results in progressive depletion of SSCs after the first wave of spermatogenesis leading to eventual spermatogenic arrest, apparently the result of a shift in the balance in SSC fate away from self-renewal and toward differentiation. Cumulating evidences have demonstrated that microRNAs are expressed in a cell-specific or stage-specific manner during spermatogenesis and acts as regulators on specific makers such as Stra8, ETV5, and PLZF. However, the post transcriptional function of PLZF still poorly elucidate in mGSCs. Bioinformatic analysis and dual luciferase reporter assay showed that miR-19b-3p binds the 3'UTR of PLZF, suggesting that PLZF is a direct target of miR-19b-3p. The profile of miR-19b-3p and PLZF analyzed in dairy goat testis at different age showed that miR-19b-3p was significantly up-regulated in goat testis at 1, 3, 6 months and downregulated at 12, 18, and 24 months which was inversely correlated with PLZF in the same testis. Focusing on the role of miR-19b-3p, we found that miR-19b-3p changes c-KIT and mTOR signaling through PLZF to promote proliferation in goat nGSCs and infertile mice testes. Over-expression of PLZF significantly reversed miR-19b-3p-mediated proliferation in mice testes. We found also that miR 19b-3p reduced heterochromatin-mediated senescence through PLZF localized on HP1alpha. Taken together, our findings indicate that miR-19b-3p promotes proliferation and reduces heterochromatin-mediated senescence through PLZF in mGSCs. PMID- 29171025 TI - 25-Hydroxy vitamin D3 serum concentration in dogs with acute polyradiculoneuritis compared to matched controls. AB - OBJECTIVES: To determine if dogs with acute polyradiculoneuritis have lower serum 25-hydroxy vitamin D3 concentration compared to a control group of dogs with idiopathic epilepsy. MATERIALS AND METHODS: Retrospective case-control study of 21 dogs with acute canine polyradiculoneuritis and 21 control dogs with idiopathic epilepsy matched for year and season of presentation from a referral hospital population in the UK. Serum concentration of 25-hydroxy vitamin D3 was compared between groups using Student's t-test. RESULTS: Dogs with acute canine polyradiculoneuritis had significantly lower (P=0.033) serum 25-hydroxy vitamin D3 concentration (87.1 nmol/L +/-55.4 nmol/L) compared to a control group with idiopathic epilepsy (113 nmol/L +/-66.3 nmol/L). CLINICAL SIGNIFICANCE: The cause and clinical significance of the altered vitamin D status in dogs with acute polyradiculoneuritis are not clear and require further investigation. Our findings pave the way for improved understanding of acute canine polyradiculoneuritis and, potentially, improved clinical management, if a causal role for 25-hydroxy vitamin D3 is defined.

AB - Two cases of hepatocellular carcinoma (HCC) in 2 female captive golden-headed lion tamarins (Leontopithecus chrysomelas) are described. HCC was diagnosed in both, with pulmonary metastasis in one of them. Neoplastic cells were positive for hepatocyte-specific antigen (HSA) by immunohistochemistry, confirming the diagnosis. PMID- 29171027 TI - On the Validity of Beer-Lambert Law and its Significance for Sunscreens. AB - The sun protection factor (SPF) is the most important quantity to characterize the performance of sunscreens. As the standard method for its determination is based on clinical trials involving irradiation of human volunteers, calculations of sunscreen performance have become quite popular to reduce the number of in vivo studies. Such simulations imply the calculation of UV transmittance of the sunscreen film using the amounts and spectroscopic properties of the UV absorbers employed, and presuppose the validity of the Beer-Lambert law. As sunscreen films on human skin can contain considerable concentrations of UV absorbers, it is questioned whether the Beer-Lambert law is still valid for these systems. The results of this work show that the validity of the Beer-Lambert law is still given at the high concentrations at which UV absorbers occur in sunscreen films on human skin. PMID- 29171028 TI - The mechanosensitive Piezo1 channel: structural features and molecular bases underlying its ion permeation and mechanotransduction. AB - The evolutionarily conserved Piezo family of proteins, including Piezo1 and Piezo2, encodes the long-sought-after mammalian mechanosensitive cation channels that play critical roles in various mechanotransduction processes such as touch, pain, proprioception, vascular development and blood pressure regulation. Mammalian Piezo proteins contain over 2500 amino acids with numerous predicted transmembrane segments, and do not bear sequence homology with any known class of ion channels. Thus, it is imperative, but challenging, to understand how they serve as effective mechanotransducers for converting mechanical force into electrochemical signals. Here, we review the recent major breakthroughs in determining the three-bladed, propeller-shaped structure of mouse Piezo1 using the state-of-the-art cryo-electron microscopy (cryo-EM) and functionally dissecting out the molecular bases that define its ion permeation and mechanotransduction properties, which provide key insights into clarifying its oligomeric status and pore-forming region. We also discuss the hypothesis that the complex Piezo proteins can be deduced into discrete mechanotransduction and ion-conducting pore modules, which coordinate to fulfil their specialized function in mechanical sensing and transduction, ion permeation and selection. PMID- 29171029 TI - Stress degradation of edaravone: Separation, isolation and characterization of major degradation products. AB - In the present study the International Conference on Harmonization-prescribed stress degradation was carried out to study the degradation profile of edaravone. To establish a Quality by Design (QbD)-assisted stability-indicating assay, the reaction solutions in which different degradation products were formed were mixed. Plackett Burman and central composite design were used to screen and optimize experimental variables to resolve edaravone and its impurities with good peak symmetry using an RP C18 column. The method was validated according to International Conference on Harmonization guidelines. Seven unknown and two known degradation products were identified and characterized by LC-MS/MS. Two major degradation products formed under thermal degradation were isolated and characterized as 4-(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl-4-(4,5 dihydro-5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-3-methyl-1-phenyl-1H-pyrazol 5(4H)-one and 3-hydroxy-dihydro-thiazolo[1-(2-methyl-buta-1,3dienyl)-1 phenylhydrazine]5-one. The degradation pathways of degradants were proposed based on m/z values.

AB - PURPOSE: Total variation minimization (TVM) is a popular and useful method for accurate CT reconstruction from few-views and limited-angle data. However, the optimization procedure of previous TVM-based algorithms is very time-consuming. The purpose of this paper was to accelerate the high image quality CT reconstruction from few-views and limited-angle data. METHOD: A new optimization algorithm based on the optimization transfer principle is proposed. The proposed algorithm uses TVM as the regularization term of the cost function that ensures the quality of the CT image reconstructed from few-views and limited-angle data. Additionally, half of the square of the difference between the original projection and the forward projection is used as the fidelity term. We then proved that the regularization term, i.e., 2-norm TV, is a convex function. Based on the convexity of the regularization and fidelity terms, a separable quadratic surrogate (SQS) function was proposed to substitute the regularization and fidelity terms. The solution of the cost function can be obtained by minimizing the SQS function and building the next SQS function at the minimum point. RESULTS: Both numerical simulations and simulations using real experimental data showed that the proposed algorithm reconstruct high-quality CT image from few views and limited-angle data. The differences between the image reconstructed by the proposed algorithm and the images reconstructed by the previous algorithms are very small. However, the proposed algorithm required less than 1/10 time of the computational time of the previous algorithms. The image quality is not assessed in a rigorous way. CONCLUSION: The proposed algorithm can greatly accelerate the accurate CT reconstruction from few-views and limited-angle data relative to previous algorithms.

AB - PURPOSE: To compare two different fragmentation patterns in femtosecond laser assisted cataract surgery (FLACS) in terms of phaco values, postoperative endothelial cell count (ECC) and corneal thickness (CT). METHODS: This non randomized, retrospective cross-sectional study included patients with senile cataract of grade 3 who underwent FLACS using the LenSx laser system. In Group 1 (32 eyes), lens fragmentation was created as a cross pattern. In Group 2 (35 eyes), lens fragmentation was created as a hybrid pattern. Intraoperative measurements were of the femtosecond procedure time, the ultrasound (US) total time, effective phacoemulsification time (EPT) and mean phacoemulsification power (MPP). Postoperative measurements were of CT and ECC at day 1, day 7 and 4 weeks after surgery. RESULTS: MPP and the US total time were significantly less with the hybrid pattern (P < 0.001, and P = 0.003). The EPT did not differ between the two groups (P = 0.266). The CT increased significantly in Group 1 from pre operative to first day after surgery (28.1 +/- 14.9 in Group 1, and 9.8 +/- 15.3 in Group 2) (P < 0.001). The loss in ECC as a percentage was significantly greater in Group 1, 1 day, 1 week and 1 month after surgery (P = 0.18, 0.49 and 0.07, respectively). CONCLUSION: The hybrid fragmentation method resulted in less time spent with the phaco being on and with less phaco power. It also caused less loss in ECC and milder changes in CT during the early post-operative time. 50:319 323, 2018. (c) 2017 Wiley Periodicals, Inc. PMID- 29171032 TI - Immunological differences between insect venom-allergic patients with and without immunotherapy and asymptomatically sensitized subjects. AB - BACKGROUND: Currently available tests are unable to distinguish between asymptomatic sensitization and clinically relevant Hymenoptera venom allergy. A reliable serological marker to monitor venom immunotherapy (VIT) does also not exist. Our aim was to find reliable serological markers to predict tolerance to bee and vespid stings. METHODS: We included 77 asymptomatically sensitized subjects, 85 allergic patients with acute systemic sting reactions, and 61 allergic patients currently treated with VIT. Levels of sIgE and sIgG4 to bee and vespid venom, rApi m 1, and rVes v 5 were measured immediately after allergic sting reactions or before sting challenges and 4 weeks later. All sting challenges were tolerated. The inhibitory activity was determined using BAT inhibition and ELIFAB assay. RESULTS: Median sIgG4 levels were 96-fold higher in VIT patients (P < .001) while sIgE/sIgG4 ratios were consistently lower (P < .001). The ELIFAB assay was paralleled by low sIgE/sIgG4 ratios in VIT patients, showing markedly higher allergen-blocking capacity (P < .001). An almost complete inhibition of the basophil response was seen in all patients treated with vespid venom, but not in those treated with bee venom. Four weeks after the sting, sIgE and sIgG4 levels were increased in allergic and asymptomatically sensitized patients, but not in VIT patients. CONCLUSION: Immunological responses after stings varied in bee and vespid venom-allergic patients. In patients under VIT, sIgE and sIgG4 remained completely stable after sting challenges. Monitoring VIT efficacy was only possible in vespid venom allergy, and the sIgG4 threshold for rVes v 5 had the highest sensitivity to confirm tolerance. The BAT inhibition test was the most reliable tool to confirm tolerance on an individual basis. PMID- 29171033 TI - Actin cytoskeleton remodeling drives epithelial-mesenchymal transition for hepatoma invasion and metastasis in mice. AB - : High invasiveness is a hallmark of human hepatocellular carcinoma (HCC). Large tumors predict invasion and metastasis. Epithelial-mesenchymal transition (EMT) is crucial for cancer invasion and metastasis. However, the mechanisms whereby large tumors tend to undergo EMT remain unclear. We conducted a subgenome-wide screen and identified KLHL23 as an HCC invasion suppressor by inhibiting EMT. KLHL23 binds to actin and suppresses actin polymerization. KLHL23 silencing induced filopodium and lamellipodium formation. Moreover, EMT was suppressed by KLHL23 through its action on actin dynamics. Traditionally, actin cytoskeleton remodeling is downstream of EMT reprogramming. It is therefore intriguing to ask why and how KLHL23 inversely regulates EMT. Activation of actin cytoskeleton remodeling by either KLHL23 silencing or treatment with actin cytoskeleton modulators augmented cellular hypoxic responses in a cell-density-dependent manner, resulting in hypoxia-inducible factor (HIF) and Notch signals and subsequent EMT. Environmental hypoxia did not induce EMT unless actin cytoskeleton remodeling was simultaneously activated and only when cells were at high density. The resulting EMT was reversed by either adenosine 5'-triphosphate supplementation or actin polymerization inhibitors. Down-regulation of KLHL23 was associated with invasion, metastasis, and poor prognosis of HCC and pancreatic cancer. Correlations of tumor size with EMT and inverse association of expression of KLHL23 with HIF/Notch signals were further validated in patient-derived xenograft HCCs in mice. CONCLUSION: Simultaneously activation of actin cytoskeleton remodeling by intrinsic (such as KLHL23 down-regulation) or microenvironment cues is crucial for cell-density-dependent and hypoxia-mediated EMT, providing a mechanistic link between large tumor size and invasion/metastasis. Our findings provide a means of developing the prevention and treatment strategies for tumor invasion and metastasis. (Hepatology 2018;67:2226-2243). PMID- 29171034 TI - Retrospective estimation of the electric and magnetic field exposure conditions in in vitro experimental reports reveal considerable potential for uncertainty. AB - Experiments on cell cultures exposed to extremely low frequency (ELF, 3-300 Hz) magnetic fields are often subject to multiple sources of uncertainty associated with specific electric and magnetic field exposure conditions. Here we systemically quantify these uncertainties based on exposure conditions described in a group of bioelectromagnetic experimental reports for a representative sampling of the existing literature. The resulting uncertainties, stemming from insufficient, ambiguous, or erroneous description, design, implementation, or validation of the experimental methods and systems, were often substantial enough to potentially make any successful reproduction of the original experimental conditions difficult or impossible. Without making any assumption about the true biological relevance of ELF electric and magnetic fields, these findings suggest another contributing factor which may add to the overall variability and irreproducibility traditionally associated with experimental results of in vitro exposures to low-level ELF magnetic fields.

AB - Alternating recurrent event data arise frequently in clinical and epidemiologic studies, where 2 types of events such as hospital admission and discharge occur alternately over time. The 2 alternating states defined by these recurrent events could each carry important and distinct information about a patient's underlying health condition and/or the quality of care. In this paper, we propose a semiparametric method for evaluating covariate effects on the 2 alternating states jointly. The proposed methodology accounts for the dependence among the alternating states as well as the heterogeneity across patients via a frailty with unspecified distribution. Moreover, the estimation procedure, which is based on smooth estimating equations, not only properly addresses challenges such as induced dependent censoring and intercept sampling bias commonly confronted in serial event gap time data but also is more computationally tractable than the existing rank-based methods. The proposed methods are evaluated by simulation studies and illustrated by analyzing psychiatric contacts from the South Verona Psychiatric Case Register. PMID- 29171036 TI - Prenatal diagnosis of posterior fossa anomalies: Additional value of chromosomal microarray analysis in fetuses with cerebellar hypoplasia. AB - OBJECTIVE: To elucidate the relationship between copy number variations (CNVs) detected by high-resolution chromosomal microarray analysis (CMA) and the type of prenatal posterior fossa anomalies (PFAs), especially cerebellar hypoplasia (CH). METHODS: This study involved 77 pregnancies with PFAs who underwent CMA. RESULTS: Chromosomal aberrations including pathogenic CNVs and variants of unknown significance were detected in 31.2% (24/77) of all cases by CMA and in 18.5% (12/65) in fetuses with normal karyotypes. The high detection rate of clinically significant CNVs was evident in fetuses with cerebellar hypoplasia (54.6%, 6/11), vermis hypoplasia (33.3%, 1/3), and Dandy-Walker malformation (25.0%, 3/12). Compare with fetuses without other anomalies, cases with CH and additional malformations had the higher CMA detection rate (33.3% vs 88.9%). Three cases of isolated unilateral CH with intact vermis and normal CMA result had normal outcomes. The deletion of 5p15, 6q terminal deletion, and X chromosome aberrations were the most frequent genetic defects associated with cerebellar hypoplasia. CONCLUSION: Among fetuses with PFA, those with cerebellar hypoplasia, vermis hypoplasia, or Dandy-Walker malformation are at the highest risk of clinically significant CNVs. Chromosomal microarray analysis revealed the most frequent chromosomal aberrations associated with CH. PMID- 29171037 TI - Stochastic phenotype switching leads to intratumor heterogeneity in human liver cancer. AB - : Intratumor heterogeneity is increasingly recognized as a major factor impacting diagnosis and personalized treatment of cancer. We characterized stochastic phenotype switching as a mechanism contributing to intratumor heterogeneity and malignant potential of liver cancer. Clonal analysis of primary tumor cell cultures of a human sarcomatoid cholangiocarcinoma identified different types of self-propagating subclones characterized by stable (keratin-7-positive or keratin 7-negative) phenotypes and an unstable phenotype consisting of mixtures of keratin-7-positive and keratin-7-negative cells, which lack stem cell features but may reversibly switch their phenotypes. Transcriptome sequencing and immunohistochemical studies with the markers Zeb1 and CD146/MCAM demonstrated that switching between phenotypes is linked to changes in gene expression related but not identical to epithelial-mesenchymal transition. Stochastic phenotype switching occurred during mitosis and did not correlate with changes in DNA methylation. Xenotransplantation assays with different cellular subclones demonstrated increased tumorigenicity of cells showing phenotype switching, resulting in tumors morphologically resembling the invasive component of primary tumor and metastasis. CONCLUSION: Our data demonstrate that stochastic phenotype switching contributes to intratumor heterogeneity and that cells with a switching phenotype have increased malignant potential.

AB - We investigated whether exposure to the 915 MHz radiofrequency identification (RFID) signal affected circulating blood cells in rats. Sprague-Dawley rats were exposed to RFID at a whole-body specific absorption rate of 2 W/kg for 8 h per day, 5 days per week, for 2 weeks. Complete blood counts were performed after RFID exposure, and the CD4+ /CD8+ ratio was determined by flow cytometry. The number of red blood cells (RBCs) and the values of hemoglobin, hematocrit, and RBC indices were increased in the RFID-exposed group compared with those in the cage-control and sham-exposed groups (P < 0.05). However, the RBCs and platelet numbers were within normal physiologic response ranges. The number of white blood cells, including lymphocytes, was decreased in RFID-exposed rats. However, there was no statistically significant difference between the sham-exposed and RFID exposed groups in terms of T-cell counts or CD4+ /CD8+ ratio (P > 0.05). Although the number of circulating blood cells was significantly altered by RFID exposure at a whole-body specific absorption rate of 2 W/kg for 2 weeks, these changes do not necessarily indicate that RFID exposure is harmful, as they were within the normal physiological response range.

AB - OBJECTIVES: To evaluate the long-term efficacy of treating nasal telangiectasias with the TRASER device. METHODS: Subjects from the TRASER efficacy analysis clinical trial were invited for a 1-year follow-up. Standardized photographs were taken to compare to baseline. The same clinical trial evaluator graded the subjects' current vessel clearance using the 5-point telangiectasia scale. The data was compiled and analyzed. RESULTS: Of the subjects with available follow-up data, 44% maintained "complete vessel clearance," 44% dropped down one grade to "almost complete vessel clearance," and 11% dropped down to "moderately clear vessel clearance." All showed clinically significant improvement in nasal telangiectasias from baseline. CONCLUSIONS: The TRASER effectively treats nasal telangiectasias with minimal to mild recurrence at 1-year follow-up. Lasers Surg. Med. 50:61-63, 2018. (c) 2017 Wiley Periodicals, Inc. PMID- 29171040 TI - Hypoxia-inducible factor-1alpha/interleukin-1beta signaling enhances hepatoma epithelial-mesenchymal transition through macrophages in a hypoxic-inflammatory microenvironment. AB - : The development and progression of hepatocellular carcinoma (HCC) are dependent on its local microenvironment. Hypoxia and inflammation are two critical factors that shape the HCC microenvironment; however, the interplay between the two factors and the involvement of cancer cells under such conditions remain poorly understood. We found that tumor-associated macrophages, the primary proinflammatory cells within tumors, secreted more interleukin 1beta (IL-1beta) under moderate hypoxic conditions due to increased stability of hypoxia inducible factor 1alpha (HIF-1alpha). Under persistent and severe hypoxia, we found that the necrotic debris of HCC cells induced potent IL-1beta release by tumor associated macrophages with an M2 phenotype. We further confirmed that the necrotic debris-induced IL-1beta secretion was mediated through Toll-like receptor 4/TIR domain-containing adapter-inducing interferon-beta/nuclear factor kappa-light-chain-enhancer of activated B cells signaling in a similar, but not identical, fashion to lipopolysaccharide-induced inflammation. Using mass spectrometry, we identified a group of proteins with O-linked glycosylation to be responsible for the necrotic debris-induced IL-1beta secretion. Following the increase of IL-1beta in the local microenvironment, the synthesis of HIF-1alpha was up-regulated by IL-1beta in HCC cells through cyclooxygenase-2. The epithelial-mesenchymal transition of HCC cells was enhanced by overexpression of HIF-1alpha. We further showed that IL-1beta promoted HCC metastasis in mouse models and was predictive of poor prognosis in HCC patients. CONCLUSION: Our findings revealed an HIF-1alpha/IL-1beta signaling loop between cancer cells and tumor-associated macrophages in a hypoxic microenvironment, resulting in cancer cell epithelial-mesenchymal transition and metastasis; more importantly, our results suggest a potential role of an anti-inflammatory strategy in HCC treatment.

AB - BACKGROUND: Increased prostatic smooth muscle tone and hyperplastic growth contribute to urethral obstruction and voiding symptoms in benign prostatic hyperplasia (BPH). It has been suggested that different proliferative potential of stromal cells between transition zone (TZ) and adjoining regions of the prostate plays a significant role in the development of BPH. However, the molecular mechanisms of this hyperplastic process remain unclear. We found tumor necrosis factor receptor-associated factor 6 (TRAF6) highly expressed in TZ stromal cells compared to peripheral zone (PZ) stromal cells by gene array analyzes. Therefore, we aim to study the potential mechanisms of stromal TRAF6 in promoting BPH progression. METHODS: Stromal cells obtained from BPH-derived primary cultures. The TRAF6-siRNA vector were constructed and transfected into cultured human BPH primary TZ stromal cells, and TRAF6-overexpressing vector were constructed and transfected into cultured human BPH primary PZ stromal cells. Stromal cells were recombined with BPH-1 cells then subcutaneously inoculated into the kidney capsule of male nude mice. Cell proliferation was evaluated by CCK-8 assay. Multiple proteins in the Akt/mTOR pathway were assessed using western blot. RESULTS: TRAF6 levels were increased in TZ stroma compared with PZ stroma of BPH. The in vitro cell culture and in vivo cell recombination revealed that selective downregulation of TRAF6 in TZ stromal cells led to suppression of the proliferation, while upregulation of TRAF6 in PZ stromal cells enhanced the proliferation. We found that the Phosphorylation and Ubiquitination of Akt as well as the Phosphorylation of mTOR, P70S6K were decreased when TRAF6 was downregulated in primary cultured TZ stromal cells of BPH. CONCLUSIONS: TRAF6 can promote the proliferation of stromal cells of BPH via Akt/mTOR signaling. Our results may make stromal TRAF6 responsible for zonal characteristic of BPH and as a promising therapeutic strategy for BPH treatment. PMID- 29171042 TI - The 2D axial transverse views of the fetal face: A new technique to visualize the fetal hard palate; methodology description and feasibility. AB - OBJECTIVES: The objectives of this study were to describe the methodology and to assess the feasibility of a simple 2D ultrasound technique to visualize the fetal hard palate (FHP) using a strict axial transverse view (ATV). METHODS: Prospective cohort of 100 singleton pregnancies, screened routinely during second trimester scans. Three operators imaged the FHP through a strict 2D ATV according to a simple methodology. An expert sonographer reviewed all images, and palate normality was confirmed at birth. Univariate and multivariate analysis of factors modifying the ability to assess the palate were performed. RESULTS: Feasibility of imaging the FHP was obtained in 95% of cases with no difference between the operators (P = .7). The palate was visualized directly without fetal mobilization in 46%. An earlier gestational age at scanning, a prolonged duration of the scan, fetal back positioned anteriorly, fetal head flexed, a smaller amniotic pocket, and an unmoving fetal limb significantly reduced the feasibility. All failed attempts were in fetuses with their back located in anterior and in those with a deflexed head. Multivariate analysis did not converge because of the collinearity of most parameters. CONCLUSIONS: The ATV is an easy, simple, and accessible 2D method to visualize the FHP with no additional time.

AB - Graphene oxide (GO) is considered a promising material for biological application due to its unique properties. However, the potential toxicity of GO to aquatic organism particularly bluegill sun fish cells (BF-2) is unexplored or remains poorly understood. GO-induced cytotoxicity and oxidative stress in BF-2 cells were assessed using a battery of biomarkers. Two different biological assays (3 (4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide and neutral red uptake were used to evaluate the cytotoxicity of GO on BF-2 cells. It was found that GO induced dose- and time-dependent cytotoxicity on BF-2 cells. BF-2 cells exposed to lower concentration of GO (40 MUg ml-1 ) for 24 induced morphological changes when compared to their respective controls. As evidence for oxidative stress lipid peroxidation, superoxide dismutase, catalase, reactive oxygen species and 8-hydroxy-2'-deoxyguanosine levels were increased and glutathione levels were found to decline in BF-2 cells after treatment with GO. Our findings demonstrate that GO when exposed to BF-2 fish cells cause oxidative stress. PMID- 29171044 TI - Stemming the Standard-of-Care SPRAWL: Clinician Self-Interest and the Case of Electronic Fetal Monitoring. AB - The "best interests of the patient" standard-a complex balance between the principles of beneficence and autonomy-is the driving force of ethical clinical care. Clinicians' fear of litigation is a challenge to that ethical paradigm. But is it ever ethically appropriate for clinicians to undertake a procedure with the primary goal of protecting themselves from potential legal action? Complicating that question is the fact that tort liability is adjudicated based on what most clinicians are doing, not the scientific basis of whether they should be doing it in the first place. In a court of law, clinicians are generally judged based on the "reasonably prudent" standard: what a reasonably prudent practitioner in a similar situation would do. But this legal standard can have the effect of shifting the medical standard of care-enabling a standard-of-care sprawl where actions undertaken for the primary purpose of avoiding liability reset the standard of care against which clinicians will be adjudicated. While this problem has been recognized in the legal literature, neither current ethical models of care nor legal theory offer workable solutions. One of the best examples of the conflict between evidence-based medicine and common clinical practice is the use of electronic fetal monitoring. Despite strong evidence and professional guidelines that argue against the use of EFM for healthy pregnancies, the practice persists. One of the main reasons for this is often assumed to be physicians' concerns about liability. PMID- 29171045 TI - Being Better Bodies. AB - Bioethics has an uneasy relationship with embodiment. Only with vigilance does knowledge of the body as it is lived counterbalance the momentous inertia of knowledge of the body as an object brought about by modern medical sciences. As a field tethered to detached, technical ways of knowing the world, bioethics must toil to treat the body as more than mere material and machine. To be more is, among other things, to be social-to live in the thickets of interdependence and the institutions and practices we build, hone, and defend to facilitate it. I take this tension to define the ultimate stakes of Melinda Hall's The Bioethics of Enhancement: Transhumanism, Disability, and Biopolitics. Hall homes in on transhumanism, the idea that we should embrace technology to vault beyond current human limitations. Yet the work serves as a reminder for all bioethicists and philosophers of how easily one can be led astray by otherwise irreproachable values when they are disconnected from the conditions and realities of human life, including being irremediably interdependent embodied beings. Put more acerbically, the book is a reminder of how thinking goes wrong when divorced from the principal sources out of which human appraisals emerge: our fleshy, messy, social bodies. PMID- 29171046 TI - Delegating Informed Consent. AB - Ten years ago, Megan Shinal sought the care of neurosurgeon Steven Toms for the surgical treatment of a recurrent nonmalignant tumor in the pituitary region of her brain. In their twenty-minute meeting, Shinal did not make a final decision about which surgical approach she wished to pursue. Subsequently, she spoke with Tom's physician assistant once by phone and once in person, when she signed the consent form, which did not appear to designate which surgical approach she had chosen. During the operation-a total resection-Toms perforated Shinal's carotid artery, resulting in hemorrhage, stroke, brain injury, and partial blindness. The jury found that Toms had fulfilled his informed-consent obligations prior to performing the resection; however, in June 2017, the Supreme Court of Pennsylvania overturned the decision, relying on the Pennsylvania Medical Care Availability and Reduction of Error Act. The court found that the language of the act is unambiguous in its requirement that "a physician's duty to provide information to a patient sufficient to obtain her informed consent is non delegable." Presumably, this rule of nondelegation applies beyond the surgical theater to other major treatment decisions. And it is unclear whether it applies to other professionals in a subordinate position to the treating physician, such as residents and fellows. PMID- 29171048 TI - Erratum.

AB - In 2012, Loyola University Chicago's Stritch School of Medicine became the first medical school in the United States to actively recruit and accept undocumented immigrants who received protections granted under the Deferred Action for Childhood Arrivals program that was established by presidential memorandum. By 2016, sixty-one medical schools were considering applications from DACA recipients for admission, and more than 110 students applied. According to the American Association of Medical Colleges, sixty-five DACA recipients matriculated in U.S. medical schools in the 2016-2017 school year. These students contribute both diversity and talent to our medical community; they could also have a significant impact on the care of underserved and immigrant populations. The recent decision by the Trump administration to rescind DACA therefore comes with serious pragmatic and ethical ramifications, impeding our medical community's efforts to develop a diverse and representative workforce committed to improving access to quality care for all patients. PMID- 29171049 TI - Public Health Autonomy: A Critical Reappraisal. AB - The ethical principle of autonomy is among the most fundamental in ethics, and it is particularly salient for those in public health, who must constantly balance the desire to improve health outcomes by changing behavior with respect for individual freedom. Although there are some areas in which there is a genuine tension between public health and autonomy-childhood vaccine mandates, for example-there are many more areas where not only is there no tension, but public health and autonomy come down to the same thing. These areas of overlap are often rendered invisible by a thin understanding of autonomy. Better integrating newer theoretical insights about autonomy into applied ethics can make discussions of public health ethics more rigorous, incisive, and effective. Even more importantly, bringing modern concepts of autonomy into public health ethics can showcase the many areas in which public health and autonomy have the same goals, face the same threats, and can be mutually advanced by the same kinds of solutions. This article provides a schema for relational autonomy in a public health context and gives concrete examples of how autonomy can be served through public-health interventions. It marshals insights from sociology, psychology, and philosophy to advance a theory of autonomy and coercion that recognizes three potential threats to autonomy: threats to choice sets, threats to knowledge, and threats to preferences.

A successful mid-thirties businesswoman, she is a self described social butterfly-which made her diagnosis of tongue cancer even more devastating. She came to the clinic complaining of a lump in her throat, which in most young healthy people turns out to be benign and easily treated. But not for Suzie, who had a very rare salivary tumor arising in the back of her tongue. Its slow growth was both a blessing and a curse; such tumors do not kill people quickly, but they typically require surgery. It would slowly and relentlessly grow until and unless we removed most of her tongue. In head and neck surgery, issues of appearance, identity, function, and communication are the foremost considerations when we decide when, and whether, to operate. As the adage goes, knowing when not to operate is the sine qua non of the wise surgeon. But the inverse is also true. PMID- 29171051 TI - The Real-World Ethics of Adaptive-Design Clinical Trials. AB - From the earliest application of modern randomized controlled trials in medical research, scientists and observers have deliberated the ethics of randomly allocating study participants to trial control arms. Adaptive RCT designs have been promoted as ethically advantageous over conventional RCTs because they reduce the allocation of subjects to what appear to be inferior treatments. Critical assessment of this claim is important, as adaptive designs are changing medical research, with the potential to significantly shift how clinical trials are conducted. Policy-makers are swiftly moving to encourage greater use of adaptive designs. In 2016, the newly enacted 21st Century Cures Act instructed the Food and Drug Administration to help product sponsors incorporate adaptive methods into proposed clinical trial protocols and applications for investigational drugs and also biological products. In this article, we review the ethical justifications commonly offered for adaptive designs, explore these arguments in the context of actual trials, and contend that clinical equipoise is a useful standard for adaptive-trial ethics. We distinguish between theoretical and clinical equipoise and explain why ethical arguments related to adaptive trials tend to focus on the former. Yet we contend that theoretical equipoise can be an unreliable standard for adaptive ethics. While we contend that clinical equipoise is the most critical principle for the primary ethical concerns posed by adaptive trials, we suggest ethical approaches to deal with some additional concerns unique to adaptive designs. PMID- 29171052 TI - Social Practices. AB - In one way or another, several pieces in the November-December 2017 of the Hastings Center Report reflect an insistence on turning away from abstractions to learn how a whole community understands a problem at issue-how a community understands what's at stake in individuals' autonomous choices, how a community understands the results of a clinical trial, how a community understands, and generates and adjusts, medical standards. In the lead article, Kayte Spector Bagdady and colleagues argue that, given extensive research showing that electronic fetal monitoring during childbirth offers very little benefit to the mother and child, a mechanism is needed to ensure that the medical standard of care is based on the right kinds of considerations. The core claim of the second article, by Laura Bothwell and Aaron Kesselheim, is that adaptive-trial designs are premised on the idea that trial designs should be maximally persuasive to the medical community. In the third article, Frederick Zimmerman argues that a richer understanding of autonomy makes it possible to see that public health is more frequently compatible with autonomy than is commonly recognized. A supplement to the issue contains a special report that explores what "just reproduction" means "in the face of multifarious understandings of both justice and autonomy and in light of increasingly complex and costly reproductive technologies." PMID- 29171054 TI - The Sticky Standard of Care. AB - The problem at the heart of "Stemming the Standard-of-Care Sprawl: Clinician Self Interest and the Case of Electronic Fetal Monitoring," an article by Kayte Spector-Bagdady and colleagues in the November-December 2017 issue of the Hastings Center Report, is the persistence of a suboptimal standard of care long after evidence-driven approaches would dictate a change. That problem is not simply defensive medicine, or what the authors call "standard-of-care sprawl." Instead, it is that, in some cases, the standard of care lags behind best practices. It gets stuck. The authors point to the genesis of the stickiness problem in their passing reference to a core truth: "The problem is that standard of care is not synonymous with best or evidence-based medicine." In my view, we might best understand the persistence of ineffective and even harmful medical interventions by acknowledging the regulatory vacuum in which such practices thrive. It is by default, not by design, that the profession relies on medical malpractice law to set the boundaries on acceptable practice. PMID- 29171055 TI - Global bioethics.

The prime minister of Serbia, Ana Brnabic, spoke of the significance of bringing together an international community of bioethicists, acknowledging that ethical, social, and legal issues surrounding gene editing technologies transcend national boundaries. Europe's Oviedo Convention prohibits human germline gene editing, and UNESCO's Universal Declaration on the Human Genome and Human Rights says that germline editing "could be contrary to human dignity," an assault on humanity itself. Whether one agrees or not, engaging with the idea forces us to think about what it means to be part of the global human community and about the moral significance of the human genome to creating that community. The conference highlighted for me how challenging having international, much less global, conversations about bioethics can be. PMID- 29171056 TI - "What's in a name?" CAR-T Gene Therapy.

Events in late 2016 raised concerns that the FDA's evidentiary standards were being weakened, compromising the agency's ability to adequately perform its regulatory and public health responsibilities. Two developments most directly contributed to these fears-the approval of eteplirsen, a treatment for Duchenne muscular dystrophy, against the recommendations of both FDA staff and an advisory committee and the December 2016 signing of the 21st Century Cures Act, which encouraged greater use by the FDA of "real-world" evidence not obtained through randomized controlled trials. The arrival of the Trump administration-with its deregulatory, industry-friendly approach-has only amplified concerns over the future of the FDA. It is too early to know whether the recent developments are truly harbingers of an FDA less likely to prevent unsafe or ineffective products from reaching the market. But elements in the two events-the role of patient narratives in deliberations regarding eteplirsen and the enthusiasm for real-world evidence in the 21st Century Cures Act-raise critical issues for the future of evidence in the FDA's work. The rigorous, inclusive approach under way to consider issues related to real-world evidence provides a model for a similarly needed inquiry regarding public participation in FDA decision-making.

AB - OBJECTIVES: To assess visibility of the acetabular cup in total hip replacement and to determine the value of direct and indirect signs of iliopsoas impingement syndrome with ultrasound. METHODS: Ultrasound examinations were performed by a single operator in 17 patients with iliopsoas impingement syndrome and 48 control patients. Cup visibility, contact between the cup and psoas tendon, and the presence of indirect signs of iliopsoas impingement syndrome were investigated in all patients. When the acetabular cup was visible, its size and position in relation to the psoas tendon were recorded. RESULTS: Anterior cup visibility (P = .03), contact with the psoas tendon (P < .001), psoas tendinopathy (P = .02), and iliopsoas bursitis (P < .001) were significantly associated with iliopsoas impingement syndrome, the latter reported with specificity of 100%. In the sagittal plane at the level of the psoas tendon, a maximum sagittal length of greater than 5 mm and a posteroanterior cup shift of 3 mm or greater yielded respective sensitivities of 82% and 59% and specificities of 81% and 100%. CONCLUSIONS: When iliopsoas impingement syndrome is clinically suspected, the presence of iliopsoas bursitis or a posteroanterior cup shift of greater than 3 mm under the psoas tendon serve to confirm the diagnosis. In the absence of these conditions, a therapeutic test may be necessary because of the incomplete, albeit high, specificity of other signs.

AB - Children's early numeracy outcomes set the foundation for mathematics learning in their future school years. This study examined how different family and individual variables were associated with the numeracy interest and competence of disadvantaged young children in the Philippines. The numeracy and literacy skills of 673 children living in low-middle income communities were tested. Their parents were also asked to complete a questionnaire on demographics, their home numeracy practices, attitudes about numeracy learning, and children's numeracy interest. Structural equation modelling analyses showed that children's numeracy interest was linked with their parents' practices and attitudes. Children's numeracy competence, on the other hand, was related to their gender, age, socioeconomic status, and literacy abilities. These findings suggest that family and individual variables might play different roles in disadvantaged children's early numeracy development. Moreover, parents can be encouraged to make effective use of home numeracy experiences to promote their children's numeracy competence. Statement of contribution What is already known on this subject? In developed countries, home environment is occasionally found to link with early numeracy development. Some individual variables are also found to play significant roles in early numeracy development. What does this study add? Among young Filipino children from disadvantaged backgrounds, home environment is related to numeracy interest. Family socioeconomic status plays a significant role in early numeracy competence. Early literacy and numeracy skills are interrelated with each other.

AB - PURPOSE: Experimental dosimetry of high-dose-rate (HDR) 192 Ir brachytherapy (BT) sources is complicated due to high dose and dose-rate gradients, and softening of photon energy spectrum with depth. A single crystal synthetic diamond detector microDiamond (PTW 60019, Freiburg, Germany) has a small active volume, high sensitivity, direct readout, and nearly water-equivalent active volume. The purpose of this study was to evaluate the suitability of microDiamond detectors for the determination of absorbed dose to water around HDR 192 Ir BT sources. Three microDiamond detectors were used, allowing for the comparison of their properties. METHODS: In-phantom measurements were performed using microSelectron and VariSource iX HDR 192 Ir BT treatment units. Their treatment planning systems (TPSs), Oncentra (v. 4.3) and BrachyVision (v. 13.6), respectively, were used to create irradiation plans for a cubic PMMA phantom with the microDiamond positioned at one of three source-to-detector distances (SDDs) (1.5, 2.5, and 5.5 cm) at a time. The source was stepped in increments of 0.5 cm over a total length of 6 cm to yield absorbed dose of 2 Gy at the nominal reference-point of the detector. Detectors were calibrated in 60 Co beam in terms of absorbed dose to water, and Monte Carlo (MC) calculated beam quality correction factors were applied to account for absorbed-dose energy dependence. Phantom correction factors were applied to account for differences in dimensions between the measurement phantom and a water phantom used for absorbed dose calculations made with a TPS. The same measurements were made with all three of the detectors. Additionally, dose-rate dependence and stability of the detectors were evaluated in 60 Co beam. RESULTS: The percentage differences between experimentally determined and TPS-calculated absorbed doses to water were from -1.3% to +2.9%. The values agreed to within experimental uncertainties, which were from 1.9% to 4.3% (k = 2) depending on the detector, SDD and treatment delivery unit. No dose rate or intrinsic energy dependence corrections were applied. All microDiamonds were comparable in terms of preirradiation dose, stability of the readings and energy response, and showed a good agreement. CONCLUSIONS: The results indicate that the microDiamond is potentially suitable for the determination of absorbed dose to water around HDR 192 Ir BT sources and may be used for independent verification of TPS's calculations, as well as for QA measurements of HDR 192 Ir BT treatment delivery units at clinical sites. PMID- 29171061 TI - "Hosting" an implantable cardioverter defibrillator: A phenomenological inquiry. AB - Implantable cardioverter defibrillators (ICDs) can reduce unexpected cardiac mortality, but they also have a dramatic impact on a patient's quality of life. We aimed to explore ICD recipients' experiences in order to foster improvements in the quality of care. Analyses were done using a descriptive phenomenological method, based on qualitative interview data from a purposive sample of 20 ICD recipients. Four main themes emerged: living with fear; relying on technology; knowing about the ICD and how to live with it; and coping with the effects of the ICD on daily life. ICD recipients lived in a constant state of fear due to the presence of the device and the uncertainty related to the potential electrical shocks it could deliver. This fear was compounded by changes that severely affected the quality of their daily life. ICD recipients felt they were always on the brink of death, and that although they received sufficient technical information they did not feel they received meaningful information to help them accept, live with, and cope with the device. Emotional information and support, rather than technical information, must be provided to ICD recipients to give them the ability to cope with the everyday threats they perceive because of the device. Qualitative evidence may help professionals tackle known threats to patients' quality of life and increase the quality of care. PMID- 29171062 TI - Mixture drug-count response model for the high-dimensional drug combinatory effect on myopathy. AB - Drug-drug interactions (DDIs) are a common cause of adverse drug events (ADEs). The electronic medical record (EMR) database and the FDA's adverse event reporting system (FAERS) database are the major data sources for mining and testing the ADE associated DDI signals. Most DDI data mining methods focus on pair-wise drug interactions, and methods to detect high-dimensional DDIs in medical databases are lacking. In this paper, we propose 2 novel mixture drug count response models for detecting high-dimensional drug combinations that induce myopathy. The "count" indicates the number of drugs in a combination. One model is called fixed probability mixture drug-count response model with a maximum risk threshold (FMDRM-MRT). The other model is called count-dependent probability mixture drug-count response model with a maximum risk threshold (CMDRM-MRT), in which the mixture probability is count dependent. Compared with the previous mixture drug-count response model (MDRM) developed by our group, these 2 new models show a better likelihood in detecting high-dimensional drug combinatory effects on myopathy. CMDRM-MRT identified and validated (54; 374; 637; 442; 131) 2-way to 6-way drug interactions, respectively, which induce myopathy in both EMR and FAERS databases. We further demonstrate FAERS data capture much higher maximum myopathy risk than EMR data do. The consistency of 2 mixture models' parameters and local false discovery rate estimates are evaluated through statistical simulation studies. PMID- 29171063 TI - Enzyme-linked immunosorbent assays (ELISA) based on thread, paper, and fabric. AB - This paper describes enzyme-linked immunosorbent assays (ELISAs) utilizing microfluidic thread/paper-based analytical devices (MUTPAD), microfluidic fabric based analytical devices (MUFAD), and microfluidic thread-based analytical devices (MUTAD). Here, the quantitative detection of biotinylated goat anti-mouse IgG (system one) and rabbit IgG (system two) antibodies via colorimetric analysis is detailed. In both systems, antibody is spotted on the detection site and subjected to a series of washes, addition of streptavidin-alkaline phosphatase (Strep-ALP) (system 1) or alkaline phosphatase (ALP)-conjugated secondary antibody (system 2), and colorimetric substrate. The devices are scanned and analyzed yielding a correlation between inverse yellow (or purple) intensity. For system one, a linear range of detection at low concentrations of streptavidin alkaline phosphatase (Strep-ALP) was observed befire the enzyme reached a Vmax . At higher concentrations of Strep-ALP, saturation is achieved for both the MUTPAD and MUFAD devices. For system two, the IC50 values obtained for the non trifurcated and trifurcated MUTADs were determined to be 180.2 fmol/zone and 133.8 fmol/zone, respectively. The IC50 value was demonstrated to be 1034 fmol/zone and 208.6 fmol/zone for the MUTPADs and MUFADs, respectively. For all devices the lowest concentration of Strep-ALP or rabbit IgG used in the assay was 3.75 * 10-4 mg/mL and 0.7 fmol/zone, respectively. The development of this technology should further facilitate the use of these platforms for ELISA to detect and quantitate antibodies. PMID- 29171064 TI - Analysis of ear side of mobile phone use in the general population of Japan. AB - This study aimed to clarify the distribution of the ear side of mobile phone use in the general population of Japan and clarify what factors are associated with the ear side of mobile phone use. Children at elementary and junior high schools (n = 2,518) and adults aged >=20 years (n = 1,529) completed an Internet-based survey. Data were subjected to a logistic regression analysis. In children, due to the tendency to use the dominant hand, we analyzed the factors associated with the use of right ear in right-handed people. Statistically significant differences were observed only in talk time per call (odds ratio (OR) = 2.17; 95% confidence interval (CI): 1.22-3.99). In adults, due to the tendency to use the left ear, we analyzed factors associated with the use of left ear in right-handed people. Significant differences were observed in those aged 30-39 years (OR = 2.55; 95% CI: 1.79-3.68), those aged 40-49 years (OR = 3.08; 95% CI: 2.15-4.43), those aged >50 years (OR = 1.85; 95% CI: 1.20-2.85), and in those with a percentage of total talk time when using mobile phones at work of 51-100% (OR = 1.75; 95% CI: 1.21-2.55). We believe that future epidemiological studies on mobile phone use can be improved by considering the trends in mobile phone use identified in this study. Bioelectromagnetics. 39:53-59, 2018.

PMID- 29171066 TI - Association of Serum Vitamin D Level and Carotid Atherosclerosis: A Systematic Review and Meta-analysis. AB - Vitamin D deficiency is associated with an increased risk of subclinical atherosclerosis. To explore the potential link of the serum vitamin D level with carotid atherosclerosis, this meta-analysis assessed the correlation between vitamin D and carotid intima-media thickness as well as carotid atherosclerotic plaque. PubMed, Embase, Web of Science, and Cochrane Library databases were searched until the end of March 2017. Clinical studies investigating the relationship between vitamin D and carotid atherosclerosis were included. The outcome data were extracted according to the inclusion criteria and pooled for an effect estimate by a random-effects model. Of the 506 initially retrieved studies, 11 studies involving a total of 16,434 participants were included in the meta-analysis. Newcastle-Ottawa Quality Assessment Scale scores suggested that the included studies were of high quality. The pooled effects estimate showed that the serum vitamin D level was negatively associated with carotid atherosclerosis (odds ratio, 0.95; 95% confidence interval [CI], 0.93-0.96), with substantial heterogeneity among the individual studies (I2 = 54%). Furthermore, a subgroup analysis suggested that hypovitaminosis D was associated with an 0.85 fold decrease in the odds of having a higher carotid intima-media thickness (95% CI, 0.76-0.96; P < .05; I2 = 69%). Additionally, the pooled analysis also indicated that the serum vitamin D level was a protective factor against increased carotid plaque (odds ratio, 0.95; 95% CI, 0.93-0.97; P < .05; I2 = 29%). Funnel plots and the Egger regression test showed the absence of a publication bias. In this meta-analysis, we comprehensively revealed a close link between vitamin D deficiency and carotid atherosclerosis. Patients with hypovitaminosis D might have extra requirements for preventive and therapeutic measures against early atherosclerosis, thus reducing the cardiovascular disease risk in the long term. PMID- 29171067 TI - Toward Scintillator High-Gain Avalanche Rushing Photoconductor Active Matrix Flat Panel Imager (SHARP-AMFPI): Initial fabrication and characterization. AB - PURPOSE: We present the first prototype Scintillator High-Gain Avalanche Rushing Photoconductor Active Matrix Flat Panel Imager (SHARP-AMFPI). This detector includes a layer of avalanche amorphous Selenium (a-Se) (HARP) as the photoconductor in an indirect detector to amplify the signal and reduce the effects of electronic noise to obtain quantum noise-limited images for low-dose applications. It is the first time avalanche a-Se has been used in a solid-state imaging device and poses as a possible solution to eliminate the effects of electronic noise, which is crucial for low-dose imaging performance of AMFPI. METHODS: We successfully deposited a solid-state HARP structure onto a 24 * 30 cm2 array of thin-film transistors (TFT array) with a pixel pitch of 85 MUm. The HARP layer consists of 16 MUm of a-Se with a hole-blocking and electron-blocking layer to prevent charge injection from the high-voltage bias and pixel electrodes, respectively. An electric field (ESe ) up to 105 V MUm-1 was applied across the a-Se layer without breakdown. A 150 MUm thick-structured CsI:Tl scintillator was used to form SHARP-AMFPI. The x-ray imaging performance is characterized using a 30 kVp Mo/Mo beam. We evaluate the spatial resolution, noise power, and detective quantum efficiency at zero frequency of the system with and without avalanche gain. The results are analyzed using cascaded linear system model (CLSM). RESULTS: An avalanche gain of 76 +/- 5 was measured at ESe = 105 V MUm-1 . We demonstrate that avalanche gain can amplify the signal to overcome electronic noise. As avalanche gain is increased, image quality improves for a constant (0.76 mR) exposure until electronic noise is overcome. Our system is currently limited by poor optical transparency of our high-voltage electrode and long integrating time which results in dark current noise. These two effects cause high-spatial frequency noise to dominate imaging performance. CONCLUSIONS: We demonstrate the feasibility of a solid-state HARP x-ray imager and have fabricated the largest active area HARP sensor to date. Procedures to reduce secondary quantum and dark noise are outlined. Future work will improve optical coupling and charge transport which will allow for frequency DQE and temporal metrics to be obtained. PMID- 29171069 TI - List of Referees. PMID- 29171068 TI - A T-cell diagnostic test for cystic echinococcosis based on Antigen B peptides. AB - Cystic echinococcosis (CE) immunodiagnosis is still imperfect. We recently set-up a whole-blood test based on the interleukin (IL)-4 response to the native Antigen B (AgB) of Echinococcus granulosus. However, AgB is encoded by a multigene family coding for five putative subunits. Therefore, the aims of this study were to analyse the IL-4 response to peptides spanning the immunodominant regions of the five AgB subunits and to evaluate the accuracy of this assay for CE diagnosis. Peptides corresponding to each subunit were combined into five pools. A pool containing all peptides was also used (total pool). IL-4 evaluated by enzyme linked immunosorbent assay was significantly higher in patients with CE compared to those without (NO-CE subjects) when whole-blood was stimulated with AgB1 and with the total pool. Moreover, IL-4 levels in response to the total pool were significantly increased in patients with active cysts. Receiver Operator Curve analysis identified a cut-off point of 0.59 pg/mL predicting active cysts diagnosis with 71% sensitivity and 82% specificity in serology-positive CE patients. These data, if confirmed in a larger cohort, offer the opportunity to develop new diagnostic tools for CE based on a standardized source of AgB as the peptides. PMID- 29171070 TI - Music for reducing the anxiety and pain of patients undergoing a biopsy: A meta analysis. AB - AIM: This study aimed to evaluate the efficacy of music therapy for reducing the anxiety and pain of patients who underwent a biopsy. BACKGROUND: Music can affect human anxiety and pain by triggering a neuroendocrine effect. Clinical study results indicated that music can influence the anxiety and pain caused by invasive procedures. There is no effective solution for anxiety and pain arising from a biopsy. Although researchers in this field have different views, music still holds promise in reducing the anxiety and pain in patients undergoing the biopsy. DESIGN: Systematic review and meta-analysis of randomized controlled trials. DATA SOURCES: Systematic searches were conducted in PubMed, Embase, Medline and Cochrane databases for studies reported in the English language. The review period covered 2000 - December 2016. The outcome measure of interest was anxiety and pain. METHODS: This review followed Cochrane methods. Studies were selected according to the PICOS framework. The methodological quality of studies was assessed with the Cochrane risk of bias tool. A systematic review of effectiveness was conducted by using GRADE approach. RESULTS: Nine randomized controlled trials with a total of 326 participants in the music intervention group and 323 controls met the inclusion criteria. Music had a tendency towards decreasing systolic blood pressure before the biopsy, State-Trait Anxiety Inventory scores after the biopsy, diastolic blood pressure after the biopsy and heart rate after the biopsy. Similarly, music also tended to be more effective for controlling pain after the biopsy. There was moderate quality evidence for the outcome: State-Trait Anxiety Inventory scores after the biopsy; and low- or very low-quality evidence for other outcomes. CONCLUSION: Music can be used for patients before and during the biopsy procedure. This approach may be performed by nurses to promote the recovery of patients after the biopsy. PMID- 29171071 TI - Person-centred, web-based support in pregnancy and early motherhood for women with Type 1 diabetes mellitus: a randomized controlled trial. AB - AIMS: To report results from and explore use of a multicentre, parallel-group, unblinded, randomized controlled trial testing the effectiveness in terms of well being and diabetes management of a person-centred, web-based support programme for women with Type 1 diabetes, in pregnancy and postpartum. METHODS: Between 2011 and 2014, 174 pregnant women with Type 1 diabetes were randomly allocated (1:1) to web-based support and standard care (intervention group, n=83), or standard care (control group, n=91). The web-based support consisted of evidence based information; a self-care diary for monitoring of daily activities; and peer support in a discussion forum. The primary outcomes (mean difference, measured at 6 months after childbirth) were well-being and diabetes management. RESULTS: No differences were found with regard to the primary outcome measure scores for general well-being [1.04 (95% CI -1.28 to 3.37); P=0.68] and self-efficacy of diabetes management [0.08 (95% CI -0.12 to 0.28); P= 0.75], after adjustment for baseline differences in the insulin administration method, nor with regard to the secondary outcome measures. CONCLUSIONS: At 6 months after childbirth, the web based support plus standard care was not superior to standard care in terms of general well-being or self-efficacy of diabetes management. This might be explained by the low number of participants who had a high activity level. Few simultaneously active participants in the web-based programme and stressors in motherhood and diabetes postpartum were the main barriers to its use. Further intervention studies that offer web-based support are needed, with lessons learned from the present study. (Clinicaltrials.gov identification number: NCT015665824). PMID- 29171072 TI - Proteomic profiling of integral membrane proteins associated to pathogenicity in Vibrio parahaemolyticus strains. AB - Vibrio parahaemolyticus has been recognized as the causal agent of early mortality syndrome and is currently considered an emerging shrimp disease causing losses of millions in the aquaculture industry. Integral membrane proteins are widely recognized as pathogenicity factors involved in essential mechanisms for V. parahaemolyticus infection, which makes them attractive as therapeutic targets. However, their physico-chemical properties and weak expression has resulted in under-representation of these proteins in conventional bottom-up proteomics, making integral membrane proteomics a challenging task. Integral membrane proteins from a bacterial strain isolated from the hepatopancreases of white shrimp with early mortality syndrome and identified by 16S rRNA sequencing as V. parahaemolyticus and an ATCC strain that is pathogenic for humans were obtained by a sequential extraction method and subjected to relative quantification and identification by isobaric Tags for Relative and Absolute Quantitation. A homology database search resulted in identification of more than two hundred proteins, 35 of which are recognized as pathogenic factors showed statistically significant differential accumulation between the strains. These proteins are mainly associated with adherence, secretion systems, cell division, transport, lysogenization, movement and virulence. Identification of pathogenicity-related proteins in V. parahaemolyticus provides valuable information for developing strategies based on molecular mechanisms that inhibit these proteins, which may be useful therapeutic targets for assisting the shrimp and aquaculture industry.

AB - Francisella tularensis, which causes tularemia, is an intracellular gram-negative bacterium. F. tularensis has received significant attention in recent decades because of its history as a biological weapon. Thus, development of novel vaccines against tularemia has been an important goal. The attenuated F. tularensis strain DeltapdpC, in which the pathogenicity determinant protein C gene (pdpC) has been disrupted by TargeTron mutagenesis, was investigated as a potential vaccine candidate for tularemia in the present study. C57BL/6J mice immunized s.c. with 1 * 106 CFUs of DeltapdpC were challenged intranasally with 100* the median lethal dose (LD50 ) of a virulent SCHU P9 strain 21 days post immunization. Protection against this challenge was achieved in 38% of immunized C57BL/6J mice administered 100 LD50 of this strain. Conversely, all unimmunized mice succumbed to death 6 days post challenge. Survival rates were significantly higher in vaccinated than in unimmunized mice. In addition, DeltapdpC was passaged serially in mice to confirm its stable attenuation. Low bacterial loads persisted in mouse spleens during the first to tenth passages. No statistically significant changes in the number of CFUs were observed during in vivo passage of DeltapdpC. The inserted intron sequences for disrupting pdpC were completely maintained even after the tenth passage in mice. Considering the stable attenuation and intron sequences, it is suggested that DeltapdpC is a promising tularemia vaccine candidate.

AB - AIM: To summarize the associations between weight stigma and physiological and psychological health for individuals who are overweight or obese. BACKGROUND: Weight stigma can be defined as individuals experiencing verbal or physical abuse secondary to being overweight or obese. Weight stigma has negative consequences for both physiological and psychological health. DESIGN: A quantitative systematic review. DATA SOURCES: PubMed, PsycINFO, CINAHL and MEDLINE from 1 January 2008 - 30 July 2016. REVIEW METHODS: A systematic review was conducted using the Cochrane Collaboration guidelines, the PRISMA statement guidelines and the quality assessment from the National Heart, Lung and Blood Institute. Inclusion criteria consisted of quantitative studies that examined the associations between weight stigma and physiological and psychological health outcomes in adults who were overweight or obese. Exclusion criteria consisted of qualitative studies, literature reviews, expert opinions, editorials and reports on weight stigma without health outcomes or with behavioural outcomes and intervention studies that reduced weight stigma. A quality appraisal of the selected studies was conducted. RESULTS: A total of 33 studies met the eligibility criteria. Weight stigma was positively associated with obesity, diabetes risk, cortisol level, oxidative stress level, C-reactive protein level, eating disturbances, depression, anxiety, body image dissatisfaction and negatively associated with self-esteem among overweight and obese adults. CONCLUSION: Weight stigma is associated with adverse physiological and psychological outcomes. This conclusion highlights the need to increase public and professional awareness about the issue of weight stigma and the importance of the further development of assessment and prevention strategies of weight stigma. PMID- 29171077 TI - Louisa May Alcott and Hospital Sketches: An innovative approach to gender and nursing professionalization. AB - AIM: To show the development of an emerging nursing profession through the eyes of Louisa May Alcott and Hospital Sketches. BACKGROUND: In Hospital Sketches, Louisa May Alcott recounts her experiences when she worked as a nurse of injured soldiers during the American Civil War, in an autobiographically and masked referential way, which allows her to negotiate between transgression and convention. Unlike other reviews, in this paper the relevance of nursing remains highlighted. DESIGN: Discussion paper. DATA SOURCES: Existing literature in databases, history books and our own reading of facts. IMPLICATIONS FOR NURSING: Illuminating overlooked meanings hidden in nurses' personal sources enables to approach their contribution to history, improve their visibility and project the future of nursing. Nursing care, whether domestic or professional, was and remains a catalyst for change. CONCLUSION: Through Alcott's words, we understand the transition of nursing care as a gradual extension of the middle-class woman's domestic role and a progressive definition of nurses' identity. In particular, we highlight how certain professional nursing nuances which appear in the text are compatible with the gradual extension of the boundaries of women's domesticity. Furthermore, Alcott's use of literary devices reveals the delicate balance between women's domestic role and some new nursing professional features, which anticipates nursing professionalization. PMID- 29171078 TI - Men across a range of ethnicities have a higher prevalence of diabetes: findings from a cross-sectional study of 500 000 UK Biobank participants. AB - AIMS: Studies show that white men have a higher prevalence of Type 2 diabetes mellitus than women at a given age and BMI, but equivalent standardized data for other ethnic groups in the UK are sparse. METHODS: This cross-sectional study analysed UK Biobank data from 489 079 participants to compare the prevalence of diabetes mellitus across four major ethnic groups including: 471 700 (96.4%) white, 7871 (1.6%) South Asian, 7974 (1.6%) black and 1534 (0.3%) Chinese participants, before and after standardizing for age, socio-economic status (SES), BMI and lifestyle factors including physical activity, TV viewing, fruit and vegetable intake, processed meat, red meat, oily fish, alcohol intake and smoking. A subgroup analysis of South Asians was also undertaken. RESULTS: Crude diabetes prevalence was higher in men across all four ethnicities. After standardizing for age, SES, BMI and lifestyle factors, a significant sex difference in diabetes prevalence persisted in white (men 6.0% vs. women 3.6%), South Asian (21.0% vs. 13.8%) and black individuals (13.3% vs. 9.7%) (P < 0.0001); there was a non-significant difference between Chinese men and women (7.1% vs. 5.5%) (P = 0.211). Sex differences persisted across South Asian subgroups. CONCLUSIONS: Men across a range of major ethnic groups including white, South Asian and black, have a higher prevalence of diabetes compared with women of similar age, BMI, SES and lifestyle in the UK. PMID- 29171079 TI - A survey of staffing levels in paediatric diabetes services throughout the UK. AB - AIMS: To assess staffing levels of healthcare professionals involved in the care of children and young people with diabetes in the UK. METHODS: A web-based questionnaire was distributed to lead consultant paediatricians from all paediatric diabetes services in the UK between October and December 2014. Data on staffing levels and other aspects of diabetes services were collected and differences between the four nations of the UK and across the 10 English diabetes networks were explored. RESULTS: Some 175 services (93%) caring for 29 711 children and young people aged <= 24 years with diabetes participated in the survey. Northern Ireland and Wales had the lowest ratio of total staff to patient population. Nursing caseloads per one whole-time equivalent (WTE) nurse ranged from 71 patients in England to 110 patients in Northern Ireland with only 52% of the UK services meeting the Royal College of Nursing recommended nurse-to-patient ratio of > 1 : 70. Scotland and Northern Ireland had the highest ratio of consultants and fully trained doctors per 1000 patients (3.5 WTE). Overall, 17% of consultants had a Certificate of Completion of Training in Endocrinology and Diabetes. Some 44% of dietitians were able to adjust insulin dose. Only 43% of services provided 24-h access to advice from the diabetes team and 82% of services had access to a psychologist. Staffing levels adjusted for volume were not directly related to glycaemic performance of services in England and Wales. CONCLUSIONS: Wide variations in staffing levels existed across the four nations of the UK and important gaps were present in key areas. PMID- 29171080 TI - Testosterone therapy for sexual dysfunction in men with Type 2 diabetes: a systematic review and meta-analysis of randomized controlled trials. AB - AIM: To evaluate the effectiveness of testosterone therapy on a range of sexual function domains in men with Type 2 diabetes. METHOD: Electronic databases were searched for studies investigating the effect of testosterone therapy on sexual function in men with Type 2 diabetes. All randomized controlled trials were considered for inclusion if they compared the efficacy of testosterone therapy with that of placebo and reported sexual function outcomes. Statistical analysis was performed using a random-effects model, and heterogeneity was expressed using the I2 statistic. RESULTS: A total of 611 articles were screened. Six randomized control trials, in a total of 587 men with Type 2 diabetes, were eligible for inclusion. The pooled data suggested that testosterone therapy improves sexual desire (random-effects pooled effect size 0.314; 95% CI 0.082-0.546) and erectile function (random-effects pooled effect size 0.203; 95% CI 0.007-0.399) when compared with control groups. Testosterone therapy had no significant effect on constitutional symptoms or other sexual domains compared with control groups. No studies have investigated the incidence of prostate cancer, fertility and cardiovascular disease after testosterone therapy in men with Type 2 diabetes. CONCLUSION: Testosterone therapy may moderately improve sexual desire and erectile function in men with Type 2 diabetes; however, available data are limited, and the long-term risks of testosterone therapy are not known in this specific patient group. We conclude that testosterone therapy is a potential treatment for men with Type 2 diabetes non-responsive to phosphodiesterase-5 inhibitors. Testosterone therapy could be considered for men with Type 2 diabetes when potential risks and benefits of therapy are carefully considered and other therapeutic options are unsuitable.

AB - BACKGROUND: Mexican mestizo population has a pluriethnic mixture of Amerindian, European and African ancestry, predominant in most Latin American countries. Until now, there are no reports about hair characteristics in this population, necessary to define normal values, for hair diseases evaluation and comparison among other ethnic groups. METHODS: The VivoSight(r) swept-source multibeam optical coherence tomography system was used to evaluate hair diameter and shape in 30 females. Three hair samples from each volunteer were measured transversely along three distances, generating nine cross-sectional images, two measurements per image and 18 measurements per patient for a total of 540 diameter measurements. RESULTS: Minimum hair diameter (n = 540) was 0.06 mm while maximum was 0.14 mm. Mean diameter was 0.10 +/- 0.01 mm as compared with Asian hair, which ranges from 0.08 mm to 0.12 mm. On morphological analysis, Mexican Mestizo hair tends to have a round shape with homogenous diameters, resembling Caucasian and Asian hair. CONCLUSION: Mexican hair is similar to Asian hair in diameter and shape and can be classified as 'thick' hair, which make it more resistant and with more volume. Cosmetic products intended to improve hair care in this population must to consider this characteristic.

AB - AIM: To investigate how mentors form judgements and reach summative assessment decisions regarding student competence in practice. BACKGROUND: Competence assessment is a significant component of pre-registration nursing programmes in the United Kingdom. Concerns exist that assessments are subjective, lack consistency and that mentors fail to judge student performance as unsatisfactory. DESIGN: A two-stage sequential embedded mixed-methods design. Data collected 2012 2013. METHODS: This study involved a whole student cohort completing a UK undergraduate adult nursing programme (N = 41). Stage 1: quantitative data on mentor conduct of assessment interviews and the final decision recorded (N = 330 from 270 mentors) were extracted from student Practice Assessment Documents (PADs). Stage 2: mentor feedback in student PADs was used in Stimulated Recall interviews with a purposive sample of final placement mentors (N = 17). These were thematically analysed. Findings were integrated to develop a theoretically driven model of mentor decision-making. RESULTS: Course assessment strategies and documentation had limited effect in framing mentor judgements and decisions. Rather, mentors amassed impressions, moderated by expectations of an "idealized student" by practice area and programme stage that influenced their management and outcome of the assessment process. These impressions were accumulated and combined into judgements that informed the final decision. This process can best be understood and conceptualized through the Brunswik's lens model of social judgement. CONCLUSION: Mentor decisions were reasoned and there was a shared understanding of judgement criteria and their importance. This impression-based nature of mentor decision-making questions the reliability and validity of competency-based assessments used in nursing pre-registration programmes.

AB - OBJECTIVES: Although qualitative alteration of the subsynovial connective tissue in the carpal tunnel is considered to be one of the most important factors in the pathophysiologic mechanisms of carpal tunnel syndrome (CTS), little information is available about the microcirculation in the subsynovial connective tissue in patients with CTS. The aims of this study were to use contrast-enhanced ultrasonography (US) to evaluate blood flow in the subsynovial connective tissue proximal to the carpal tunnel in patients with CTS before and after carpal tunnel release. METHODS: The study included 15 volunteers and 12 patients with CTS. The blood flow in the subsynovial connective tissue and the median nerve was evaluated preoperatively and at 1, 2, and 3 months postoperatively using contrast enhanced US. RESULTS: The blood flow in the subsynovial connective tissue was higher in the patients with CTS than in the volunteers. In the patients with CTS, there was a significant correlation between the blood flow in the subsynovial connective tissue and the median nerve (P = .01). The blood flow in both the subsynovial connective tissue and the median nerve increased markedly after carpal tunnel release. CONCLUSIONS: Our results suggest that increased blood flow in the subsynovial connective tissue may play a role in the alteration of the microcirculation within the median nerve related to the pathophysiologic mechanisms of CTS. The increase in the blood flow in the subsynovial connective tissue during the early postoperative period may contribute to the changes in intraneural circulation, and these changes may lead to neural recovery. PMID- 29171084 TI - Emerging adulthood and Type 1 diabetes: insights from the DAWN2 Study. AB - AIMS: To compare clinical, psychological, education and social variables in emerging adults (aged 18-30 years) with Type 1 diabetes with their adult counterparts aged >30 years. METHODS: A single assessment multinational sample was surveyed as part of the larger second Diabetes Attitudes, Wishes and Needs (DAWN2) study. Participants completed a series of surveys incorporating demographic as well as clinical questions (comorbidities, hypoglycaemia) and validated self-report scales concerning psychosocial (health impact, quality of life, beliefs and attitudes, self-management behaviours, healthcare experience and family support) and diabetes education factors. RESULTS: Emerging adults differed from adults aged >30 years with regard to a number of psychosocial variables. Emerging adults reported better overall quality of life, social support and support from their healthcare team compared with adults aged >30 years of age; however, emerging adults experienced greater diabetes-specific distress and were less engaged in self-management. Diabetes education was related to a number of indicators, while experience of discrimination was harmful, but these impacts did not differ between emerging adults and adults aged >30 years. An analysis of geographical regions suggested that emerging adults in North America and Europe had better well-being than older adults, while the opposite was observed in Asia. CONCLUSIONS: Emerging adults, particularly those in the later phase (ages 25-30 years) are especially at risk in terms of diabetes specific distress. There is a need for novel interventions to meet the needs of these vulnerable emerging adults more effectively.

PMID- 29171085 TI - Contrast-Enhanced Ultrasound Examination for the Assessment of Renal Perfusion in Cats with Chronic Kidney Disease. AB - BACKGROUND: Contrast-enhanced ultrasound examination (CEUS) is a functional imaging technique allowing noninvasive assessment of tissue perfusion. Studies in humans show that the technique holds great potential to be used in the diagnosis of chronic kidney disease (CKD). However, data in veterinary medicine are currently lacking. OBJECTIVES: To evaluate renal perfusion using CEUS in cats with CKD. ANIMALS: Fourteen client-owned cats with CKD and 43 healthy control cats. METHODS: Prospective case-controlled clinical trial using CEUS to evaluate renal perfusion in cats with CKD compared to healthy control cats. Time-intensity curves were created, and perfusion parameters were calculated using off-line software. A linear mixed model was used to examine differences between perfusion parameters of cats with CKD and healthy cats. RESULTS: In cats with CKD, longer time to peak and shorter mean transit times were observed for the renal cortex. In contrast, a shorter time to peak and rise time were seen for the renal medulla. The findings for the renal cortex indicate decreased blood velocity and shorter total duration of enhancement, likely caused by increased vascular resistance in CKD. Increased blood velocity in the renal medulla has not been described before and may be because of a different response to regulatory factors in cortex and medulla. CONCLUSIONS AND CLINICAL IMPORTANCE: Contrast-enhanced ultrasound examination was capable of detecting perfusion changes in cats with CKD. Further research is warranted to assess the diagnostic capabilities of CEUS in early stage of the disease process. PMID- 29171086 TI - A randomized study of prourokinase during primary percutaneous coronary intervention in acute ST-segment elevation myocardial infarction. AB - OBJECTIVES: To evaluate the efficacy and safety of intracoronary administration of prourokinase via balloon catheter during primary percutaneous coronary interventions (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). METHODS: Acute STEMI patients underwent primary PCI were randomly divided into two groups: intracoronary prourokinase (IP) group (n = 118) and control group (n = 112). During primary PCI, prourokinase or saline were injected to the distal end of the culprit lesion via balloon catheter after balloon catheter dilatation. Demographic and clinical characteristics, infarct size, myocardial reperfusion, and cardiac functions were evaluated and compared between two groups. Hemorrhagic complications and MACE occurred in the 6-months follow up were recorded. RESULTS: No significant differences were observed between two groups with respect to baseline demographic, clinical, and angiographic characteristics (P > 0.05). In IP group, more patients had complete ST segment resolution (>70%) compared with control group (P < 0.05). Patients in IP group showed lower levels of serum CK, CK-MB and TnI, and a much higher myocardial blood flow (MBF) than those in control group (P < 0.05). No significant differences of TIMI major or minor bleeding complications were observed between the two groups (P > 0.05). At 6-months follow-up, there was a trend that patients in the IP group had a less chance to have MACE, though it was not statistically different (8.5% vs 12.5%, P > 0.05). CONCLUSIONS: Intracoronary administration of prourokinase via balloon catheter during primary PCI effectively improved myocardial perfusion in STEMI patients. PMID- 29171088 TI - Comparison of Single, Averaged, and Pooled Urine Protein:Creatinine Ratios in Proteinuric Dogs Undergoing Medical Treatment. AB - BACKGROUND: Monitoring urine protein:creatinine ratios (UPC) in dogs with protein losing nephropathy (PLN) is challenging because of day-to-day variation in UPC results. HYPOTHESIS/OBJECTIVES: Determine whether single, averaged, or pooled samples from PLN dogs receiving medical treatment yield comparable UPCs, regardless of degree of proteinuria. ANIMALS: Twenty-five client-owned PLN dogs receiving medical treatment. METHODS: UPC ratios were prospectively measured in each dog utilizing 3 methods: single in-hospital sample (day 3), average sample (days 1-3), and pooled sample (equal pooling of urine from days 1-3). Bland Altman analysis was performed to evaluate agreement between methods for all dogs, as well as in subgroups of dogs (UPC <=4 or UPC >4). RESULTS: For all dogs, Bland Altman log-transformed 95% limits of agreement were -0.07-0.18 (single versus pooled UPC), -0.06-0.16 (single versus average UPC), and -0.06-0.04 (pooled versus average UPC). For dogs with UPC <=4, Bland-Altman 95% limits of agreement were -0.42-0.82 (single versus pooled UPC), -0.38-0.76 (single versus average UPC), and -0.27-0.25 (pooled versus average UPC). For dogs with UPC >4, Bland Altman 95% limits of agreement were -0.17-2.4 (single versus pooled UPC), -0.40 2.2 (single versus average UPC), and -0.85-0.43 (pooled versus average UPC). CONCLUSIONS AND CLINICAL IMPORTANCE: UPC ratios from all methods were comparable in PLN dogs receiving medical treatment. In PLN dogs with UPC >4, more variability between methods exists likely because of higher in-hospital results, but whether this finding is clinically relevant is unknown.

PMID- 29171091 TI - Internal fit of three-unit fixed dental prostheses produced by computer-aided design/computer-aided manufacturing and the lost-wax metal casting technique assessed using the triple-scan protocol. AB - Suboptimal adaptation of fixed dental prostheses (FDPs) can lead to technical and biological complications. It is unclear if the computer-aided design/computer aided manufacturing (CAD/CAM) technique improves adaptation of FDPs compared with FDPs made using the lost-wax and metal casting technique. Three-unit FDPs were manufactured by CAD/CAM based on digital impression of a typodont model. The FDPs were made from one of five materials: pre-sintered zirconium dioxide; hot isostatic pressed zirconium dioxide; lithium disilicate glass-ceramic; milled cobalt-chromium; and laser-sintered cobalt-chromium. The FDPs made using the lost wax and metal casting technique were used as reference. The fit of the FDPs was analysed using the triple-scan method. The fit was evaluated for both single abutments and three-unit FDPs. The average cement space varied between 50 MUm and 300 MUm. Insignificant differences in internal fit were observed between the CAD/CAM-manufactured FDPs, and none of the FPDs had cement spaces that were statistically significantly different from those of the reference FDP. For all FDPs, the cement space at a marginal band 0.5-1.0 mm from the preparation margin was less than 100 MUm. The milled cobalt-chromium FDP had the closest fit. The cement space of FDPs produced using the CAD/CAM technique was similar to that of FDPs produced using the conventional lost-wax and metal casting technique. PMID- 29171090 TI - 24-Hour Kinetics of Cardiac Troponin-T Using a "High-Sensitivity" Assay in Thoroughbred Chuckwagon Racing Geldings after Race and Associated Clinical Sampling Guidelines. AB - BACKGROUND: A "high-sensitivity" cardiac troponin-T (hscTnT) assay recently has been validated for use in horses and is a specific biomarker of myocardial damage. Postexercise release kinetics of cTnT utilizing the hscTnT assay have yet to be established in horses. OBJECTIVES: To determine: (1) cTnT release kinetics in racing Thoroughbreds after a high-intensity 5/8th mile Chuckwagon race; (2) the effects of age on pre- and postrace cTnT concentrations; and (3) sampling guidelines for clinicians evaluating horses presenting after exercise. ANIMALS: Samples were obtained from 38 Thoroughbred geldings aged 5-16 years before racing and immediately, 2, 3, 4, 6, 12, and 24 hour postrace. METHODS: Prospective, observational study with convenience sampling. A fifth-generation hscTnT assay was used for plasma sample analysis, and concentrations were compared at all time points. Correlations were determined between cTnT concentrations and age. Biochemistry analysis was performed to assess rhabdomyolysis, renal failure, and exercise-induced dehydration. RESULTS: All horses with measureable cTnT concentrations had significant postexercise increases in cTnT with a median peak (8.0 ng/L) at 3-hour postrace. All horses had peak postexercise cTnT concentrations 2- to 6-hour postrace <= the 99th percentile upper reference limit of 23.2 ng/L, after which all cTnT concentrations decreased until returning to baseline by 12-24 hours. There was no correlation over time between cTnT concentrations and age. CONCLUSIONS AND CLINICAL IMPORTANCE: In racing Thoroughbreds completing short-duration, high-intensity Chuckwagon races, cTnT concentrations are expected to be increased 2- to 6-hour postrace and to decrease by 12-24 hours while remaining <=23.2 ng/L throughout. This study contributes to establishing guidelines for clinical use of the hscTnT assay in exercising horses. PMID- 29171092 TI - Oral keratinocytes synthesize CTACK: A new insight into the pathophysiology of the oral mucosa. AB - The skin-associated chemokine CTACK plays a key role in many inflammatory conditions and could be instrumental in the pathophysiology of tissue-specific immunological diseases such as oral lichen planus (OLP). In this study, we investigated, by RT-PCR, ELISA, chemotaxis assays, and fluorescence-activated cell sorting (FACS), the production of CTACK in oral keratinocytes, its expression in tissues from normal and OLP patients, and its role in T-cell recruitment.CTACK was produced by the oral epithelium, and it affects chemotaxis of memory CLA+ cells to the oral epithelium. CTACK mRNA was expressed constitutively in primary oral epithelium and was increased during pro inflammatory IFN-gamma treatment. We found a constitutive production of CTACK at a protein level in oral primary cells that increased after IFN-gamma treatment. Moreover, we confirmed that CTACK attracts memory T cells and those T cells that express CLA above the level of basal migration. PMID- 29171093 TI - Government helper and citizen advocate? A case study of the multiple roles and pressures facing a nongovernmental organization contracted by government to strengthen community health in northern India. AB - While nongovernmental organizations (NGOs) can potentially strengthen valuable citizen political engagement, NGOs that are increasingly oriented towards donor and government contracts may instead contribute to depoliticizing development. Amidst competing pressures, NGO experiences and agency in managing multiple roles require examination. We present a qualitative case study of an NGO implementing a government-designed intervention to strengthen Village Health, Sanitation, and Nutrition Committees (VHSNCs) in rural north India. Despite a challenging context of community scepticism and poor government services, the NGO did successfully form VHSNCs by harnessing its respected interlocutor status, preexisting relationships, and ability to "sell" the VHSNC as a mechanism for improving local well-being. While the VHSNC enabled community members to voice concerns to government officials, improvements often failed to meet community expectations. NGO staff endured community frustration on one hand and rebuffs from lower-level officials on the other, while feeling undersupported by the government contract. Consequently, although contracted to strengthen a community institution, the NGO increasingly worked alongside VHSNC members to try to strengthen the public sector. Contrary to assumptions that NGOs become "tamed" through taking government contracts, being contracted to deliver inputs for community participation was intertwined with microlevel political action, though this came at a cost to the NGO.

PMID- 29171096 TI - Risk of acute myocardial infarction with real-world NSAIDs depends on dose and timing of exposure. AB - PURPOSE: Real-life use of nonsteroidal anti-inflammatory drugs (NSAIDs) is dynamic. This study aimed to characterize the temporal association between time varying NSAID exposure and acute myocardial infarction (MI). METHODS: Nested case control analyses were conducted on a Quebec administrative health cohort. NSAID dose, confounders, and outcome status were determined for each day of follow-up. To better account for dose and timing of past exposures, flexible weighted cumulative exposure models were also fitted. RESULTS: The cohort consisted of 233 816 older adults including 21 256 acute MI cases. Dose-related increased risks of MI were found with current use of all NSAIDs. In models not accounting for duration of use, ORs (95%CI) for the most common current daily dose vs. no current exposure were: celecoxib 200 mg: 1.16 (1.10, 1.22), diclofenac 150 mg: 1.59 (1.38, 1.84), ibuprofen 1200 mg: 1.42 (1.17, 1.74), naproxen 750 mg: 1.38 (1.21, 1.58), and rofecoxib 25 mg: 1.54 (1.43, 1.66). Weighted cumulative exposure models confirmed that all NSAIDs-including naproxen-are associated with an increased risk of MI and suggested that doses taken up to 3 weeks ago for rofecoxib, ibuprofen, and naproxen and up to 75 days ago for diclofenac and celecoxib may contribute to the current MI risk. However, the celecoxib risk seems to require continuous use for more than 30 days, whereas for other NSAIDs, a heightened MI risk occurs within 7 days. CONCLUSIONS: Weighted cumulative exposure analysis uncovered NSAID-specific differences in the immediate MI risk and how this risk seems to accumulate. KEY POINTS Accurate assessment of drug safety requires an etiologically correct model encompassing all relevant aspects of exposure. Weighted cumulative exposure models suggest that the relative importance of past doses on the risk of MI differs among NSAIDs. All common NSAIDs are associated with an increased MI risk. Celecoxib MI risk seems to depend on continuously using the drug for more than 30 days, whereas for ibuprofen, rofecoxib, diclofenac, and naproxen, a heightened MI risk occurs within 7 days of use. PMID- 29171097 TI - Usefulness of left ventricular strain analysis in patients with takotsubo syndrome during acute phase. AB - BACKGROUND: Takotsubo syndrome (TTS) is peculiar clinical condition often resembling an acute coronary syndrome and mostly affecting postmenopausal women after a stressful trigger. TTS was initially thought to be a relatively benign condition. However, current data have shown it may be associated with considerable inpatient morbidity and carry a small, but important, mortality risk. METHODS: We hypothesized that left ventricular (LV) regional and global longitudinal strain (GLS) assessed with 2D speckle tracking echocardiography could identify early systolic functional impairment and predict in-hospital cardiovascular events. We conducted a retrospective descriptive study reviewing patients with the discharge diagnosis of TCM between 2003 and 2016 at our institution. RESULTS: One hundred patients with TSS met the Modified Mayo Clinic criteria. Using 2D speckle tracking echocardiography, two independent cardiologists assessed the LV GLS as well as the longitudinal strain (LS) of 7 individual segments [basal-septal (BS); mid-septal (MS), apical-septal (AS), apex, basal-lateral (BL), mid-lateral (ML), and apical-lateral (AL)]. The inter observer variability was <5%. Mean age was 69.1 years, 87% were females, and 53% were African Americans. Mean initial LV EF was 32% +/- 9.8%. In univariate analysis, patients with worse BL, ML, and GLS profiles (means: -5.7; -3.3, and 4, respectively) had higher in-hospital mortality (P < .05). Worse BL and ML profiles (means: -8.6 and -7.3, respectively) were associated with higher prevalence of MACE (major adverse cardiovascular outcomes) (P < .05). In a multivariate analysis, mid-lateral strain >= -7 and basolateral strain >= -10 were independent predictors of in-hospital mortality and MACE + in-hospital heart failure, respectively. CONCLUSIONS: Assessment of LV global and segmental longitudinal strain by speckle tracking has important prognostic value in the acute phase of TTS. Additional large-scale studies will be needed to confirm our findings. PMID- 29171098 TI - Can bladder preservation therapy come to the center stage? AB - Decision-making in urological cancer care requires a multidisciplinary approach for refinement, but its impact on urothelial carcinoma of the bladder has not been fully addressed for the past three decades, except for the latest immunological checkpoint inhibitor approved by the U.S. Food and Drug Administration for metastatic muscle-invasive bladder cancer that is resistant to platinum-based chemotherapy. For the time being, radical cystectomy is the gold standard of curative therapy for muscle-invasive bladder cancer. Trimodal therapy that combines chemotherapy for the purpose of radiation sensitization, external beam radiotherapy and transurethral resection of bladder tumor has emerged as a potential alternative treatment option that preserves the bladder. In lack of randomized studies for bladder preservation therapy compared with surgery, the principles of management of urothelial carcinoma of the bladder have evolved in recent times, with an emphasis on bladder preservation. A number of bladder preservation techniques are available to the surgeon; however, appropriately selected patients with muscle-invasive bladder cancer should be offered the opportunity to discuss various treatment options, including organ-sparing trimodal therapy. The aim of the present study was to compare the primary outcomes of the available treatment methods and identify the sources of variance among studies. A review of various bladder preservation techniques in vogue for the management of urothelial carcinoma of the bladder is discussed. PMID- 29171095 TI - The Gastrointestinal Microbiome: A Review. AB - The gastrointestinal microbiome is a diverse consortium of bacteria, archaea, fungi, protozoa, and viruses that inhabit the gut of all mammals. Studies in humans and other mammals have implicated the microbiome in a range of physiologic processes that are vital to host health including energy homeostasis, metabolism, gut epithelial health, immunologic activity, and neurobehavioral development. The microbial genome confers metabolic capabilities exceeding those of the host organism alone, making the gut microbiome an active participant in host physiology. Recent advances in DNA sequencing technology and computational biology have revolutionized the field of microbiomics, permitting mechanistic evaluation of the relationships between an animal and its microbial symbionts. Changes in the gastrointestinal microbiome are associated with diseases in humans and animals including inflammatory bowel disease, asthma, obesity, metabolic syndrome, cardiovascular disease, immune-mediated conditions, and neurodevelopmental conditions such as autism spectrum disorder. While there remains a paucity of data regarding the intestinal microbiome in small animals, recent studies have helped to characterize its role in host animal health and associated disease states. This review is intended to familiarize small animal veterinarians with recent advances in the field of microbiomics and to prime them for a future in which diagnostic tests and therapies will incorporate these developments into clinical practice. PMID- 29171099 TI - Regional Citrate Anticoagulation for Intermittent Hemodialysis in Dogs. AB - BACKGROUND: The traditional systemic heparinization used for anticoagulation in extracorporeal therapies may cause fatal complications in animals at risk of bleeding. HYPOTHESIS/OBJECTIVES: To develop and validate a protocol of regional citrate anticoagulation (RCA) for intermittent hemodialysis in dogs. ANIMALS: A total of 172 dogs treated with hemodialysis for acute kidney injury. METHODS: In vitro titration was performed, adding trisodium citrate and calcium chloride to heparinized canine blood. A tentative protocol was used first in 66 treatments with additional heparinization and subsequently in 518 heparin-free treatments. Safety and adequacy of RCA were assessed based on clinical and laboratory monitoring, dialyzer pressure gradient, treatment completion, and visual scoring of the extracorporeal circuit. RESULTS: Addition of 1 mmol/L citrate to heparinized blood decreased the ionized calcium concentration by 0.23 mmol/L (95% confidence interval [CI], 0.16-0.30) and 1 mmol/L calcium increased it by 0.62 mmol/L (95% CI, 0.45-0.79). Heparin-free treatments were initiated with infusion of trisodium citrate (102 mmol/L) at 2.55 mmol/L blood and calcium chloride (340 mmol/L) at 0.85 mmol/L. Citrate and calcium administrations were adjusted in 27 and 34% of the treatments, respectively. Overall, anticoagulation was satisfactory in 92% of the treatments, with expected azotemia reduction in 95% (urea) and 86% (creatinine), stable dialyzer pressure gradient in 82%, and clean extracorporeal circuits in 92% of the treatments. Eighteen treatments (3.5%) were discontinued prematurely, 9 because of clotting and 9 for reasons unrelated to the RCA procedure. CONCLUSIONS AND CLINICAL IMPORTANCE: Regional citrate anticoagulation allows safe and efficient heparin-free hemodialysis in dogs at risk of bleeding. PMID- 29171100 TI - Impact of age-related macular degeneration on object searches in realistic panoramic scenes. AB - BACKGROUND: This study investigated whether realistic immersive conditions with dynamic indoor scenes presented on a large, hemispheric panoramic screen covering 180 degrees of the visual field improved the visual search abilities of participants with age-related macular degeneration (AMD). METHOD: Twenty-one participants with AMD, 16 age-matched controls and 16 young observers were included. Realistic indoor scenes were presented on a panoramic five metre diameter screen. Twelve different objects were used as targets. The participants were asked to search for a target object, shown on paper before each trial, within a room composed of various objects. A joystick was used for navigation within the scene views. A target object was present in 24 trials and absent in 24 trials. The percentage of correct detection of the target, the percentage of false alarms (that is, the detection of the target when it was absent), the number of scene views explored and the search time were measured. RESULTS: The search time was slower for participants with AMD than for the age-matched controls, who in turn were slower than the young participants. The participants with AMD were able to accomplish the task with a performance of 75 per cent correct detections. This was slightly lower than older controls (79.2 per cent) while young controls were at ceiling (91.7 per cent). Errors were mainly due to false alarms resulting from confusion between the target object and another object present in the scene in the target-absent trials. CONCLUSION: The outcomes of the present study indicate that, under realistic conditions, although slower than age-matched, normally sighted controls, participants with AMD were able to accomplish visual searches of objects with high accuracy. PMID- 29171101 TI - In vitro Inhibition of Canine Complement-Mediated Hemolysis. AB - BACKGROUND: Immune-mediated hemolytic anemia (IMHA) is the most common hematologic immune-mediated disease in dogs. Complement fixation on erythrocytes causes hemolysis. Complement inhibition decreases hemolysis in people with the hemolytic disease and also may prove effective in treating IMHA in dogs. HYPOTHESIS/OBJECTIVES: Evaluate the in vitro efficacy of 2 complement inhibitors used in humans against canine complement. METHODS: The inhibitory activity of the C3-inhibitor compstatin and recombinant human C1-esterase inhibitor (C1-INH) was evaluated using an in vitro hemolytic assay and spectrophotometric measurement of released hemoglobin. Dose-response curves for each inhibitor were generated. RESULTS: Compstatin decreased approximately 50% of canine complement-mediated hemolysis in initial experiments. This inhibition largely was lost when a new lot of drug was purchased. C1-INH showed a dose-dependent inhibition. The highest concentration of C1-INH tested (500 MUg/mL) decreased >80% of canine complement mediated hemolysis, and the lowest concentration tested (31.25 MUg/mL) decreased hemolysis >60%. CONCLUSIONS AND CLINICAL IMPORTANCE: Human C1-INH is a robust inhibitor of canine complement-mediated hemolysis, whereas compstatin was minimally and variably effective. Human C1-INH may substantially decrease complement-mediated hemolysis in dogs with IMHA and warrants further investigation.

PMID- 29171104 TI - Elevated perseveration errors on a verbal fluency task in frequent nightmare recallers: a replication. AB - A recent study reported that individuals recalling frequent idiopathic nightmares (NM) produced more perseveration errors on a verbal fluency task than did control participants (CTL), while not differing in overall verbal fluency. Elevated scores on perseveration errors, an index of executive dysfunction, suggest a cognitive inhibitory control deficit in NM participants. The present study sought to replicate these results using a French-speaking cohort and French language verbal fluency tasks. A phonetic verbal fluency task using three stimulus letters (P, R, V) and a semantic verbal fluency task using two stimulus categories (female and male French first names) were administered to 23 participants with frequent recall of NM (>=2 NM per week, mean age = 24.4 +/- 4.0 years), and to 16 CTL participants with few recalled NM (<= 1 NM per month, mean age = 24.5 +/- 3.8 years). All participants were French-speaking since birth and self-declared to be in good mental and physical health apart from their NM. As expected, groups did not differ in overall verbal fluency, i.e. total number of correct words produced in response to stimulus letters or categories (P = 0.97). Furthermore, groups exhibited a difference in fluency perseveration errors, with the NM group having higher perseveration than the CTL group (P = 0.03, Cohen's d = 0.745). This replication suggests that frequent NM recallers have executive inhibitory dysfunction during a cognitive association task and supports a neurocognitive model which posits fronto-limbic impairment as a neural correlate of disturbed dreaming. PMID- 29171103 TI - Adult functions for the Drosophila DHR78 nuclear receptor. AB - BACKGROUND: The Testicular Receptors 2 and 4 (TR2, TR4) comprise a small subfamily of orphan nuclear receptors. Genetic studies in mouse models have identified roles for TR4 in developmental progression, fertility, brain development, and metabolism, as well as genetic redundancy with TR2. Here we study the adult functions of the single Drosophila member of this subfamily, DHR78, with the goal of defining its ancestral functions in the absence of genetic redundancy. RESULTS: We show that DHR78 mutants have a shortened lifespan, reduced motility, and mated DHR78 mutant females display a reduced feeding rate. Transcriptional profiling reveals a major role for DHR78 in promoting the expression of genes that are expressed in the midgut, suggesting that it contributes to nutrient uptake. We also identify roles for DHR78 in maintaining the expression of genes in the ecdysone and Notch signaling pathways. CONCLUSIONS: This study provides a new context for linking the molecular activity of the TR orphan nuclear receptors with their complex roles in adult physiology and lifespan.

PMID- 29171105 TI - Effects of a family-support programme for pregnant women with foetal abnormalities requiring pregnancy termination: A randomized controlled trial in China. AB - AIM: We examined the effects of a family-support programme for pregnant women with foetal abnormalities in terms of family support, depression, and post traumatic stress symptoms. METHOD: A randomized controlled trial was conducted from November 2016 to June 2017. A total of 124 pregnant women with foetal abnormalities were recruited and randomly assigned to the intervention group that received a family-support programme or control group that received only routine care. Self-reported questionnaires including the Family Adaptation Partnership Growth Affection and Resolve Index, the Edinburgh Postnatal Depression Scale, and the Impact of Event Scale-Revised were administered before and after intervention. RESULTS: Relative to the control group, posttest Family Adaptation Partnership Growth Affection and Resolve Index scores and scores on the intimacy domain were significantly higher in the intervention group, the Edinburgh Postnatal Depression Scale and Impact of Event Scale-Revised scores and the scores on all subscales except the intrusion subscale were significantly lower in the intervention group. CONCLUSION: The findings of this study suggest that family-support programme represents an effective and feasible support approach of improving family support and reducing depression and post-traumatic stress symptoms for pregnant women with foetal abnormalities requiring pregnancy termination.

AB - OBJECTIVE: We inspected the relevance of CD44, ABCB1 and ADAM17 in OSCC stemness and deciphered the role of autophagy/mitophagy in regulating stemness and chemoresistance. MATERIAL AND METHODS: A retrospective analysis of CD44, ABCB1 and ADAM17 with respect to the various clinico-pathological factors and their correlation was analysed in sixty OSCC samples. Furthermore, the stemness and chemoresistance were studied in resistant oral cancer cells using sphere formation assay, flow cytometry and florescence microscopy. The role of autophagy/mitophagy was investigated by transient transfection of siATG14, GFP LC3, tF-LC3, mKeima-Red-Mito7 and Western blot analysis of autophagic and mitochondrial proteins. RESULTS: In OSCC, high CD44, ABCB1 and ADAM17 expressions were correlated with higher tumour grades and poor differentiation and show significant correlation in their co-expression. In vitro and OSCC tissue double labelling confirmed that CD44+ cells co-expresses ABCB1 and ADAM17. Further, cisplatin (CDDP)-resistant FaDu cells displayed stem-like features and higher CD44, ABCB1 and ADAM17 expression. Higher autophagic flux and mitophagy were observed in resistant FaDu cells as compared to parental cells, and inhibition of autophagy led to the decrease in stemness, restoration of mitochondrial proteins and reduced expression of CD44, ABCB1 and ADAM17. CONCLUSION: The CD44+ /ABCB1+ /ADAM17+ expression in OSCC is associated with stemness and chemoresistance. Further, this study highlights the involvement of mitophagy in chemoresistance and autophagic regulation of stemness in OSCC. PMID- 29171107 TI - Assessing sleep quality using self-report and actigraphy in PTSD. AB - Sleep disturbance is commonly reported by participants with post-traumatic stress disorder, but objective evidence of poor sleep is often absent. Here we compared self-report and actigraphic evaluations of sleep between veterans with post traumatic stress disorder and controls. Participants reported their sleep retrospectively for the month before the recording night and on the recording night. On the recording night, they wore an Actiwatch-64 and were instructed to press the marker button upon getting into bed, each time they awoke, and at their final awakening. The post-traumatic stress disorder group reported much worse sleep than controls on the Pittsburgh Sleep Quality Index for the previous month and somewhat poorer sleep on the recording night. However, on the recording night, neither diary nor actigraphic measures of number of awakenings, total time in bed, nor time lying awake after sleep onset differed between participants with and without post-traumatic stress disorder. Diary-reported number of awakenings was fewer than actigraphically captured awakenings. These results suggest a memory bias towards remembering worse sleep on the nights before the recording night. PMID- 29171108 TI - Optimization and validation of automated hippocampal subfield segmentation across the lifespan. AB - Automated segmentation of hippocampal (HC) subfields from magnetic resonance imaging (MRI) is gaining popularity, but automated procedures that afford high speed and reproducibility have yet to be extensively validated against the standard, manual morphometry. We evaluated the concurrent validity of an automated method for hippocampal subfields segmentation (automated segmentation of hippocampal subfields, ASHS; Yushkevich et al., ) using a customized atlas of the HC body, with manual morphometry as a standard. We built a series of customized atlases comprising the entorhinal cortex (ERC) and subfields of the HC body from manually segmented images, and evaluated the correspondence of automated segmentations with manual morphometry. In samples with age ranges of 6 24 and 62-79 years, 20 participants each, we obtained validity coefficients (intraclass correlations, ICC) and spatial overlap measures (dice similarity coefficient) that varied substantially across subfields. Anterior and posterior HC body evidenced the greatest discrepancies between automated and manual segmentations. Adding anterior and posterior slices for atlas creation and truncating automated output to the ranges manually defined by multiple neuroanatomical landmarks substantially improved the validity of automated segmentation, yielding ICC above 0.90 for all subfields and alleviating systematic bias. We cross-validated the developed atlas on an independent sample of 30 healthy adults (age 31-84) and obtained good to excellent agreement: ICC (2) = 0.70-0.92. Thus, with described customization steps implemented by experts trained in MRI neuroanatomy, ASHS shows excellent concurrent validity, and can become a promising method for studying age-related changes in HC subfield volumes. PMID- 29171109 TI - A systematic review of quantitative observational studies investigating psychological distress in testicular cancer survivors. AB - OBJECTIVE: Testicular cancer (TC) affects young men and may cause psychological distress despite a good prognosis. This systematic review evaluated the prevalence, severity, and correlates of anxiety, depression, fear of cancer recurrence (FCR), and distress in TC survivors. METHODS: A systematic search of literature published 1977 to 2017 was conducted to find quantitative studies including TC survivor-reported outcomes relevant to review objectives. The quality of included articles was assessed, and a narrative synthesis conducted. RESULTS: Of 6717 articles identified, 66 (39 good, 20 fair, and 7 poor quality) reporting results from 36 studies were included. Testicular cancer survivors' mean anxiety levels were higher than in the general population, while mean depression and distress were no different. Clinically significant anxiety (~1 in 5) and to a lesser extent distress (~1 in 7), but not depression, were more prevalent in TC survivors than the general population. Approximately 1 in 3 TC survivors experienced elevated FCR. Poorer psychological outcomes were more common among TC survivors who were single, unemployed/low socio-economic status, suffering from co-morbidities, experiencing worse symptoms/side effects, and using passive coping strategies. CONCLUSIONS: Many TC survivors do not experience significant psychological morbidity, but anxiety and FCR are prevalent. Inadequate coping resources (eg, low socio-economic status and social support) and strategies (eg, avoidance) and greater symptoms/side effects were associated with poorer outcomes. Theoretically driven prospective studies would aid understanding of how outcomes change over time and how to screen for risk. Age and gender appropriate interventions that prevent and manage issues specific to TC survivors are also needed. PMID- 29171110 TI - The prevalence of narcolepsy in Catalunya (Spain). AB - Previous studies have estimated an overall prevalence for narcolepsy between 15 and 70 cases per 100 000 inhabitants. We aimed to estimate the prevalence of narcolepsy in Catalunya (Catalonia), a north-east region of Spain (7 424 754 inhabitants), on 31 December 2014 by identifying all living subjects diagnosed with narcolepsy. First, we identified patients diagnosed by one of the 13 sleep, paediatric or neurological departments that perform tests regularly to diagnose narcolepsy. In a second phase, we searched for additional patients with narcolepsy in a clinical database of the primary health-care system. Clinical files were reviewed and narcolepsy diagnosis validated according to the Brighton Collaboration case definitions. Three hundred and twenty-five patients had a validated diagnosis of narcolepsy in the specialized centres (mean age: 44.6 years, range: 6-89; male: 60.3%; 85% with narcolepsy type 1), including 17.8% cases in Brighton, definition level 1, 62.5% in level 2, 15.4% in level 3 and 4.3% in level 4a. The overall prevalence for narcolepsy was 4.4; 3.7 for narcolepsy type 1 and 0.7 cases per 100 000 inhabitants for narcolepsy type 2. Fifty-six additional narcoleptic patients were identified in the primary health care system, increasing the overall prevalence to 5.2 cases per 100 000 inhabitants. Prevalence rates for narcolepsy type 1 increased from childhood to adulthood, but in subjects aged more than 50 years there was a substantial drop in prevalence rates, suggesting the presence of a significant pool of undiagnosed cases in this population. Narcolepsy can be considered a rare neurological disorder in Catalunya. PMID- 29171111 TI - Knockdown of ubiquitin D inhibits adipogenesis during the differentiation of porcine intramuscular and subcutaneous preadipocytes. AB - OBJECTIVES: Intramuscular fat (IMF) has a significant influence on porcine meat quality. Ubiquitin D (UBD) is involved in the management of diverse intracellular processes. However, its physiological functions in adipose cell differentiation and proliferation are still poorly defined. MATERIALS AND METHODS: Intramuscular and subcutaneous preadipocytes were isolated from the longissimus dorsi and neck subcutaneous deposits of Chinese native Guanzhong Black piglets (3-5 days old), respectively. Lentivirus with short hairpin RNA (shRNA) for UBD was applied to knockdown UBD expression. We used real-time PCR and Western blot analysis to detect gene expression. Lipid droplets were dyed with Oil Red O, and cell proliferation was assessed using flow cytometry, 5-ethynyl-2'-deoxyuridine incorporation and cell counting assays. RESULTS: Lipogenesis through the Akt/mTOR pathway was inhibited when preadipocytes were transfected with UBD shRNA. The expression of adipogenic genes and the number of lipid droplets were obviously diminished. Moreover, repression of UBD attenuated cell proliferation. UBD downregulation resulted in cell cycle arrest because of a decreased proportion of S-phase cells, and the expression of positive cell proliferation markers was significantly decreased. CONCLUSION: These observations illustrated that knockdown of UBD partially suppressed porcine intramuscular and subcutaneous preadipocyte adipogenesis through the Akt/mTOR signalling and inhibited cell proliferation, suggesting the essential role of UBD in the differentiation of preadipocytes.

PMID- 29171112 TI - The impact of social deprivation on the response to a randomised controlled trial of a weight management intervention (BeWEL) for people at increased risk of colorectal cancer. AB - BACKGROUND: Although 45% of colorectal cancer (CRC) cases may be avoidable through appropriate lifestyle and weight management, health promotion interventions run the risk of widening health inequalities. The BeWEL randomised controlled trial assessed the impact of a diet and activity programme in overweight adults who were diagnosed with a colorectal adenoma, demonstrating a significantly greater weight loss at 12 months in intervention participants than in controls. The present study aimed to compare BeWEL intervention outcomes by participant deprivation status. METHODS: The intervention group of the BeWEL trial (n = 163) was classified by the Scottish Index of Multiple Deprivation (SIMD) quintiles into 'more deprived' (SIMD 1-2, n = 58) and 'less deprived' (SIMD 3-5, n = 105). Socio-economic and lifestyle variables were compared at baseline to identify potential challenges to intervention adherence in the more deprived. Between group differences at 12 months in primary outcome (change in body weight) and secondary outcomes (cardiovascular risk factors, diet, physical activity, knowledge of CRC risk and psychosocial variables) were assessed by deprivation status. RESULTS: At baseline, education (P = 0.001), income (P < 0.001), spending on physical activity (P = 0.003) and success at previous weight loss attempts (P = 0.007) were significantly lower in the most deprived. At 12 months, no between group differences by deprivation status were detected for changes in primary and main secondary outcomes. CONCLUSIONS: Despite potential barriers faced by the more deprived participants, primary and most secondary outcomes were comparable between groups, indicating that this intervention is unlikely to worsen health inequalities and is equally effective across socio economic groups. PMID- 29171114 TI - Prescription drug use in pregnancy and variations according to prior psychiatric history. AB - PURPOSE: Prescription drug use during pregnancy has increased during the past decades. However, little is known about prescription drug use for high-risk pregnancies. We aimed to estimate the prevalence of redeemed prescriptions in Danish pregnant women with and without previous psychiatric history. METHODS: A Danish population-based descriptive study of 981 392 pregnancies ending in live born singletons by 586 988 women aged 15 to 55 years between 1997 and 2012, of which 113 449 (11.6%) pregnancies were by women with a psychiatric history prior to the index pregnancy. All prescription drugs redeemed during pregnancy were identified, and dispensing patterns among the women were reported by therapeutic classes of drugs, calendar year of childbirth, and trimester. RESULTS: Overall, women with psychiatric history prior to pregnancy were more likely to fill a prescription (75.8%; 95% confidence interval [CI], 75.5-76.0%), compared with women with no psychiatric history (64.5%; 95% CI, 64.4-64.6%). The difference was observed even when psychotropic drug use was excluded and in all therapeutic classes except for antineoplastic and immunomodulating drugs. The most commonly prescribed drugs were anti-infectives. Approximately 44.7% (95% CI, 44.5-45.0%) of women with psychiatric history and 31.3% (95% CI, 31.2-31.4%) of women with no psychiatric history redeemed more than one therapeutic class of drugs. CONCLUSIONS: Women with a psychiatric history were more likely to redeem prescriptions during pregnancy across almost all drug classes, especially anti infectives. Two thirds of all women redeemed at least one prescription drug during pregnancy and one third more than one drug class. KEY POINTS We mapped prescription drug use of almost 600 000 women during almost one million pregnancies with focus on women with a history of psychiatric disorder before conception compared with women with no such history. Pregnant women with a previous psychiatric disorder were more likely to redeem prescription drugs compared with pregnant women without a previous psychiatric disorder. The observed overall difference was not due to obvious differences in psychotropic drug use. The difference was evident across calendar years, all trimesters, and almost all drug classes, but to a large extent in anti-infectives, among those mainly antibiotics. Two thirds of pregnant women redeemed prescription drugs during pregnancy, and one third redeemed more than one drug class. Health professionals should be aware of comorbid conditions requiring multiple drug use during pregnancy with the risk of unknown fetal effects. PMID- 29171115 TI - Carboplatin and programmed death-ligand 1 blockade synergistically produce a similar antitumor effect to carboplatin alone in murine ID8 ovarian cancer model. AB - AIM: In advanced, platinum resistant or refractory ovarian cancer (OC), the therapeutic efficacy of carboplatin is controversial. Although anti-programmed death-1/programmed death-ligand 1 (PD-1/PD-L1) pathway blockages show great potential in cancer treatment, the antitumor effect of single anti-PD-L1 pathway monoclonal antibody (mAb) is not obvious in advanced or some poorly immunogenic tumors, including OC. We compared the effects of single or combined carboplatin and anti-PD-L1 mAb treatments and explored the possible antitumor mechanisms in a murine ID8 OC model. METHODS: C57BL/6 mice with established peritoneal ID8 OC were intraperitoneally injected with single or combined carboplatin and anti-PD L1 mAb. The formation time of ascites and their overall survival were recorded. The compositions of tumor-associated immune cells were analyzed by flow cytometry. RESULTS: A single treatment of carboplatin and combined carboplatin/PD L1 mAb induced a strong anti-ascites response. Mice treated with carboplatin presented the longest overall survival, followed by the combined remedy. Mechanistic investigation of the tumor microenvironment revealed that carboplatin and carboplatin/PD-L1 mAb increased antitumor effector CD4+ , CD8+ T cells and decreased immunosuppressive regulatory T and myeloid suppressor cells, giving rise to remarkably higher ratios of effector CD4+ , CD8+ T cells to regulatory T cells and myeloid suppressor cells in the peritoneal cavity. CONCLUSIONS: To our knowledge, this is the first report to compare the antitumor effect and potential mechanisms between carboplatin, PD-L1 mAb and their combination strategies in a murine ID8 OC model. The results of this study may deepen our understanding of OC and aid future preclinical experiments or clinical trials. PMID- 29171116 TI - Impact of weight loss on ablation outcome in obese patients with longstanding persistent atrial fibrillation. AB - AIMS: This study investigated the impact of weight loss in longstanding persistent (LSPAF) patients undergoing catheter ablation (CA). METHODS: Ninety consecutive obese LSPAF patients were approached; 58 volunteered to try weight loss interventions for up to 1 year (group 1), while 32 patients declined weight loss interventions and were included as a control (group 2). Both groups remained on antiarrhythmic drugs. If they continued to experience AF, CA was performed. Body weight was measured at 6-month intervals and arrhythmia status was assessed by event recorder, electrocardiogram (ECG), and Holter monitoring. Symptom severity and quality of life (QoL) were evaluated by AFSS and SF-36 survey, respectively. A scoring algorithm with two summary measures, physical component score (PCS) and mental component score (MCS), was prepared for QoL analysis. RESULTS: Significant reduction in body weight (median -24.9 (IQR -19.1 to -56.7) kg, P < 0.001) was observed in the group 1 patients, while no such change was seen in group 2. The PCS and MCS scores improved significantly in group 1 only, with a change from baseline of 8.4 +/- 3 (P = 0.013) and 12.8 +/- 8.2 (P < 0.02). However, AF symptom severity remained unchanged from baseline in both groups (P = 0.84). All 90 patients eventually underwent CA and received PVAI+ posterior wall+ non-PV triggers ablation. At 1-year follow-up after single procedure, 37 (63.8%) in group 1 and 19 (59.3%) patients in group 2 remained arrhythmia-free off AAD (P = 0.68). CONCLUSION: In this prospective analysis, in LSPAF patients weight loss improved QoL but had no impact on symptom severity and long-term ablation outcome. PMID- 29171117 TI - Predictive factors for emergent surgical intervention in patients with ovarian endometrioma hospitalized for pelvic inflammatory disease: A retrospective observational study. AB - AIM: The aim of this study was to identify predictive factors for emergent surgical interventions in patients with ovarian endometriomas hospitalized for pelvic inflammatory disease (PID). METHODS: We retrospectively identified 22 patients with ovarian endometriomas who were hospitalized to manage PID. Patients were divided into two groups: those who required emergent surgery after failed antibiotic therapy (emergent surgery group, n = 6) and those who were discharged with successful antibiotic therapy (conservative group, n = 16). Logistic regression analysis was performed to analyze the factors associated with emergent surgery. RESULTS: Patients in the emergent surgery group were significantly more likely to have intrauterine or intrapelvic procedures before the onset of PID compared to those in the conservative group (83% vs 38%, odds ratio 8.33, 95% confidence interval 1.02-181.3; P = 0.048). The mean interval between the onset of PID symptoms and the commencement of parenteral antibiotic therapy was significantly longer in the emergent surgery compared to the conservative group (6.5 vs 1 day, odds ratio 1.28, 95% confidence interval 1.01-1.75; P = 0.041). CONCLUSION: A history of an intrauterine or intrapelvic procedure before the onset of PID was more likely to result in emergent surgery. A longer interval between the onset of PID symptoms and the commencement of parenteral antibiotics was also associated with emergent surgery. These findings could help to identify patients with ovarian endometriomas hospitalized with PID at higher risk of emergent surgical intervention. PMID- 29171118 TI - Translesional pressure gradient and leptomeningeal collateral status in symptomatic middle cerebral artery stenosis. AB - BACKGROUND AND PURPOSE: Leptomeningeal collateral (LMC) status governs the prognosis of large artery occlusive stroke, although factors determining LMC status are not fully elucidated. The aim was to investigate metrics affecting LMC status in such patients by using computational fluid dynamics (CFD) models based on computed tomography angiography (CTA). METHODS: In this cross-sectional study, patients with recent ischaemic stroke or transient ischaemic attack attributed to atherosclerotic M1 middle cerebral artery (MCA) stenosis (50%-99%) were recruited. Demographic, clinical and imaging data of these patients were collected. Ipsilesional LMC status was graded as good or poor by assessing the laterality of anterior and posterior cerebral arteries in CTA. A CFD model based on CTA was constructed to reflect focal hemodynamics in the distal internal carotid artery, M1 MCA and A1 anterior cerebral artery. Pressure gradients were calculated across culprit MCA stenotic lesions in CFD models. Predictors for good LMC status were sought in univariate and multivariate analyses. RESULTS: Amongst the 85 patients enrolled (mean age 61.5 +/- 10.9 years), 38 (44.7%) had good ipsilesional LMC status. The mean pressure gradient across MCA lesions was 14.8 +/- 18.1 mmHg. Advanced age (P = 0.030) and a larger translesional pressure gradient (P = 0.029) independently predicted good LMCs. A lower fasting blood glucose level also showed a trend for good LMCs (P = 0.058). CONCLUSIONS: Our study suggested a correlation between translesional pressure gradient and maturation of LMCs in intracranial atherosclerotic disease. Further studies with more exquisite and dynamic monitoring of cerebral hemodynamics and LMC evolution are needed to verify the current findings. PMID- 29171119 TI - Abundant recent activity of retrovirus-like retrotransposons within and among flycatcher species implies a rich source of structural variation in songbird genomes. AB - Transposable elements (TEs) are genomic parasites capable of inserting virtually anywhere in the host genome, with manifold consequences for gene expression, DNA methylation and genomic stability. Notably, they can contribute to phenotypic variation and hence be associated with, for example, local adaptation and speciation. However, some organisms such as birds have been widely noted for the low densities of TEs in their genomes and this has been attributed to a potential dearth in transposition during their evolution. Here, we show that avian evolution witnessed diverse and abundant transposition on very recent timescales. First, we made an in-depth repeat annotation of the collared flycatcher genome, including identification of 23 new, retrovirus-like LTR retrotransposon families. Then, using whole-genome resequencing data from 200 Ficedula flycatchers, we detected 11,888 polymorphic TE insertions (TE presence/absence variations, TEVs) that segregated within and among species. The density of TEVs was one every 1.5 2.5 Mb per individual, with heterozygosities of 0.12-0.16. The majority of TEVs belonged to some 10 different LTR families, most of which are specific to the flycatcher lineage. TEVs were validated by tracing the segregation of hundreds of TEVs across a three-generation pedigree of collared flycatchers and also by their utility as markers recapitulating the phylogenetic relationships among flycatcher species. Our results suggest frequent germline invasions of songbird genomes by novel retroviruses as a rich source of structural variation, which may have had underappreciated phenotypic consequences for the diversification of this species rich group of birds. PMID- 29171120 TI - Quality of development and reporting of dietetic intervention studies in primary care: a systematic review of randomised controlled trials. AB - BACKGROUND: High-quality research methodologies and clear reporting of studies are essential to facilitate confidence in research findings. The aim of the present study was to conduct an in-depth examination of the methodological quality and reporting of studies included in a recent systematic review of dietitians' effectiveness at providing individualised nutrition care to adult patients. METHODS: The methodological quality and reporting of 27 Randomised Controlled Trials (RCTs) were appraised using the UK Medical Research Council (MRC) Guidelines for complex interventions and the CONSORT checklist for reporting RCTs. A quality appraisal checklist was developed for each guideline/assessment tool aiming to evaluate the extent to which each study met the designated criteria. Excerpts from studies that best addressed criteria were collated to provide exemplary accounts of how criteria may be achieved in future studies. RESULTS: None of the reviewed studies met more than half of the MRC Guidance criteria, indicating that there is clear room for improvement in reporting the methodological underpinnings of these studies. Similarly, no studies met all criteria of the CONSORT checklist, suggesting that there is also room for improvement in the design and reporting of studies in this field. CONCLUSIONS: Dietitians, researchers and journal editors are encouraged to use the results and exemplary accounts from this review to identify key aspects of studies that could be improved in future research. Improving future research will enhance the quality of the evidence-base that investigates the outcomes of dietary interventions involving dietitians. PMID- 29171121 TI - Insular damage, new-onset atrial fibrillation and outcome after acute intracerebral hemorrhage. AB - BACKGROUND AND PURPOSE: Cortical insular damage is associated with cardiac arrhythmias and an increased risk of death. We investigated the influence of insular damage on the outcome of patients with acute intracerebral hemorrhage as well as the frequency and predictors of new-onset atrial fibrillation (nAF). METHODS: We studied consecutive patients with intracerebral hemorrhage from 2013 to 2016. We identified those patients who underwent continuous electrocardiographic monitoring (>=24 h), known atrial fibrillation and recent ischemic stroke. We prospectively collected demographic data, vascular risk factors, neurological severity, vital signs, radiological data, nAF and mortality at 3 months. Bivariate and multivariate regression analyses were performed. RESULTS: We evaluated 347 patients whose mean age was 73.5 +/- 14.0 years (50.7% of them were men). We selected 183 patients to study the frequency and risk factors of nAF (mean age, 69.1 +/- 14.7 years; 52.5% of them were men). We observed that 11/183 (6.0%) had nAF. Insular damage [odds ratio (OR), 7.6; 95% confidence interval (CI), 2.1-27.7] was associated with nAF. A total of 138/347 patients died within the first 3 months and insular damage was detected in 99/347 of them. Predictors of death were age (OR, 1.07; 95% CI, 1.04-1.10), blood glucose (OR, 1.00 per mg/dL;, 95% CI, 1.00-1.01), Glasgow Coma Scale score (OR, 0.85; 95% CI, 0.77-0.92), hematoma volume (OR, 1.02 per mL; 95% CI, 1.01-1.04), intraventricular hemorrhage (OR, 1.93; 95% CI, 1.03-3.64) and insular damage (OR, 3.98; 95% CI, 2.00-7.90). CONCLUSIONS: The frequency of nAF in our patients was 6.0%. Insular damage was a risk factor for nAF and an independent predictor of death at 3 months. PMID- 29171122 TI - The Mutation in the Single-Crystal Structural Transformation Process, Induced by the Combined Stimuli of Temperature and Solvent. AB - A 2D coordination polymer containing a free ligand (Lf ), fixed by hydrogen bonds, transformed into a 3D metal-organic framework (MOF) in a single-crystal to single-crystal fashion. This transformation occurs through the combined stimuli of temperature and solvent. From 50 to 90 degrees C, a series of changes take place in a gradual form: the Lf is slowly moved to the cobalt center, which is accompanied by a contraction of unit cell and hydrogen bond. When the temperature rises to 95 degrees C, the hydrogen bond is destroyed, and Lf is suddenly combined with the cobalt ion to form an intricate 3D structure. This mutation process is irreversible and cannot occur just with the stimulus of either temperature or solvent. Notably, even under the combined stimuli, this mutation phenomena is difficult to reproduce when the solvent species and proportions change. DFT calculations were used to try to explain the nature of the phenomenon. PMID- 29171123 TI - Investigation of Known Genetic Mutations of Arabian Horses in Egyptian Arabian Foals with Juvenile Idiopathic Epilepsy. AB - BACKGROUND: The carrier status of lavender foal syndrome (LFS), cerebellar abiotrophy (CA), severe combined immunodeficiency (SCID), and occipitoatlantoaxial malformation (OAAM1) in foals with juvenile idiopathic epilepsy (JIE) is unknown. HYPOTHESIS/OBJECTIVES: To determine the carrier status of LFS, CA, SCID, and OAAM1 in foals with JIE. ANIMALS: Ten foals with JIE. MATERIALS AND METHODS: Archived DNA samples were tested for known genetic mutations causing LFS, CA, SCID, and OAAM1. The inclusion criteria consisted of having been diagnosed with JIE by ruling out other causes of seizures in foals and supported by electroencephalographic examination. RESULTS: Ten Egyptian Arabian horses (5 females and 5 males) were phenotyped as foals with JIE by electroencephalography (EEG). All foals were negative for the genetic mutations that cause LFS, CA, SCID, and OAAM1 except for 1 foal that was a carrier of CA. CONCLUSIONS AND CLINICAL IMPORTANCE: Juvenile idiopathic epilepsy of Egyptian Arabian foals and LFS appear to be phenotypically and genetically distinct disorders. There was no apparent association between JIE and LFS, CA, SCID, and OAAM1. PMID- 29171124 TI - KDM6A promotes chondrogenic differentiation of periodontal ligament stem cells by demethylation of SOX9. AB - OBJECTIVES: KDM6A has been demonstrated critical in the regulation of cell fates. However, whether KDM6A is involved in cartilage formation remains unclear. In this study, we investigated the role of KDM6A in chondrogenic differentiation of PDLSCs, as well as the underlying epigenetic mechanisms. METHODS: KDM6A shRNA was transfected into PDLSCs by lentivirus. The chondrogenic differentiation potential of PDLSCs was assessed by Alcian blue staining. Immunofluorescence was performed to demonstrate H3K27me3 and H3K4me3 levels during chondrogenesis. SOX9, Col2a1, ACAN and miRNAs (miR-29a, miR-204, miR-211) were detected by real-time RT-PCR. Western blot was performed to evaluate SOX9, H3K27me3 and H3K4me3. RESULTS: The production of proteoglycans in PDLSCs was decreased after knockdown of KDM6A. Depletion of KDM6A inhibited the expression of SOX9, Col2a1, ACAN and resulted in increased H3K27me3 and decreased H3K4me3 levels. EZH2 inhibitor rescued the chondrogenic potential of PDLSCs after knockdown of KDM6A by regulating H3K27me3. Additionally, miR-29a, miR-204 and miR-211 were also involved in the process of PDLSCs chondrogenesis. CONCLUSIONS: KDM6A is required in chondrogenic differentiation of PDLSCs by demethylation of H3K27me3, and EZH2 inhibitor could rescue chondrogenesis of PDLSCs after knockdown of KDM6A. It could be inferred that upregulation of KDM6A or application of EZH2 inhibitor might improve mesenchymal stem cell mediated cartilage regeneration in inflammatory tissue destruction such as osteoarthritis. PMID- 29171125 TI - A Microsporidian Infection in Phoronids (Phylum Phoronida): Microsporidium phoronidi n. sp. from a Phoronis embryolabi. AB - Microsporidia-like spores (2.0-3.0 * 1.3-1.5 MUm) were discovered upon examination of histological sections taken from Phoronis embryolabi Temereva, Chichvarkhin 2017 found inhabiting burrows of shrimps Nihonotrypeae japonica (Decapoda, Callianassidae) from the Sea of Japan, Russia. Ultrastructural examination of spores revealed one nucleus and a uniform polar filament of 7-11 coils. Representatives of the phylum Phoronida have never been recorded as hosts of microsporidia. Parasites developed in vasoperitoneal tissue and caused formation of multinucleate syncytia. Basing on unique host and fine morphology, we assign the novel finding to Microsporidium phoronidi n. sp. and place provisionally in the collective genus Microsporidium.

AB - BACKGROUND: Children whose 11th fetal week falls in pollen season (spring) reportedly have an increased risk of sensitization to food allergens. No such finding has been reported for pet allergens. OBJECTIVE: The aim of the study was to (i) evaluate the incidence of pet (dog and cat) sensitization according to the season of the 11th fetal week and (ii) whether the association between pet exposure and respective sensitization is modified by the coincidence of the 11th fetal week with pollen season. METHODS: The study population comprised all children (born between 2001 and 2006) in the province of South Karelia, Finland (N = 5920). Their data of immunoglobulin E antibodies and skin prick tests to pet allergens (N = 538) were collected from patient records and linked with questionnaire data on pet exposure. RESULTS: The seasonal incidence peak of cat sensitization was observed in children whose 11th fetal week occurred in June (7.4%) and that of dog sensitization in April (3.8%) and June (4.7%). The relative rate (RR) for cat sensitization was 2.92 (95% CI 1.40-6.08) in children with cat exposure alone, 8.53 (4.07-17.86) in children with cat and fetal pollen exposures and 0.61 (0.20-1.83) in children exposed to pollen alone, compared with children without these exposures. The respective RRs for dog sensitization were 2.17 (1.13-4.19), 4.40 (2.19-8.83) and 1.65 (0.77-3.53). CONCLUSIONS AND CLINICAL RELEVANCE: Coincidence of the first fetal trimester with pollen season strengthens the association between pet exposure and respective sensitization. Pollen exposure at early pregnancy may deviate immune system towards Th2-type reactivity promoting development of specific allergy in case allergen exposure occurred. Therefore, primary prevention of allergic diseases may need to begin during early pregnancy. PMID- 29171127 TI - How many geriatricians should, at minimum, be staffing health regions in Australia? AB - In any particular region, determining an adequate, quantifiable geriatrician full time equivalent required to run geriatric medicine services comprehensively - that is spanning both inpatient and outpatient settings - remains an imperfect science. Whilst workforce planning may be addressed through 'demand versus supply' simulations, 'specialist-to-patient ratios' (SPRs) may be a useful additional workforce metric. There has never been a yardstick SPR, which 'defines' a satisfactory level of geriatrician manpower in any particular Australian hospital catchment. Here, a new methodology is proposed (tailored specifically to Australian geriatrics), illustrating how we may begin to transparently deduce such a national benchmark SPR. Allowing for some empiricism, the method presently favours an SPR approximating '0.4 full-time equivalent of geriatrician time per 10 000 head of population' in regions with 'average' population age distribution; this level of manpower may afford specialist assessment of targeted patients (widely capturing geriatric cases from acute to community settings). Further discussion on workforce planning methodologies is warranted. PMID- 29171128 TI - Soil pH as the chief modifier for regional nitrous oxide emissions: New evidence and implications for global estimates and mitigation. AB - Nitrous oxide (N2 O) is a greenhouse gas that also plays the primary role in stratospheric ozone depletion. The use of nitrogen fertilizers is known as the major reason for atmospheric N2 O increase. Empirical bottom-up models therefore estimate agricultural N2 O inventories using N loading as the sole predictor, disregarding the regional heterogeneities in soil inherent response to external N loading. Several environmental factors have been found to influence the response in soil N2 O emission to N fertilization, but their interdependence and relative importance have not been addressed properly. Here, we show that soil pH is the chief factor explaining regional disparities in N2 O emission, using a global meta-analysis of 1,104 field measurements. The emission factor (EF) of N2 O increases significantly (p < .001) with soil pH decrease. The default EF value of 1.0%, according to IPCC (Intergovernmental Panel on Climate Change) for agricultural soils, occurs at soil pH 6.76. Moreover, changes in EF with N fertilization (i.e. DeltaEF) is also negatively correlated (p < .001) with soil pH. This indicates that N2 O emission in acidic soils is more sensitive to changing N fertilization than that in alkaline soils. Incorporating our findings into bottom-up models has significant consequences for regional and global N2 O emission inventories and reconciling them with those from top-down models. Moreover, our results allow region-specific development of tailor-made N2 O mitigation measures in agriculture. PMID- 29171130 TI - First experience in the UK of treating women with recurrent urinary tract infections with the bacterial vaccine Uromune(r). AB - OBJECTIVES: To determine the effectiveness of Uromune(r) in preventing recurrent urinary tract infections (UTIs) in women. PATIENTS AND METHODS: A total of 77 women with microbiology-proven recurrent UTIs were given Uromune sublingual vaccine for a period of 3 months. Time to first UTI recurrence since treatment and adverse events were prospectively recorded in a follow-up period of up to 12 months. RESULTS: Of the 77 women, 75 completed the treatment. Of the 75 women who completed treatment, 59 (78%) had no subsequent UTIs in the follow-up period. Prior to treatment, all women had experienced a minimum of three or more episodes of UTI during the preceding 12 months. Proportionally, the majority of recurrences occurred in postmenopausal women. One patient had to stop treatment because of an adverse event (rash over face and neck). CONCLUSION: This prospective study suggests that Uromune is safe and effective at preventing UTIs in women. Further research is required in larger groups of patients for longer treatment times. An international double-blind randomized control trial comparing Uromune with placebo is currently underway. PMID- 29171129 TI - The influence of body mass index and age on C-peptide at the diagnosis of type 1 diabetes in children who participated in the diabetes prevention trial-type 1. AB - BACKGROUND/OBJECTIVE: The extent of influence of BMI and age on C-peptide at the diagnosis of type 1 diabetes (T1D) is unknown. We thus studied the impact of body mass index Z-scores (BMIZ) and age on C-peptide measures at and soon after the diagnosis of T1D. METHODS: Data from Diabetes Prevention Trial-Type 1 (DPT-1) participants <18.0 years at diagnosis was analyzed. Analyses examined associations of C-peptide measures with BMIZ and age in 2 cohorts: oral glucose tolerance tests (OGTTs) at diagnosis (n = 99) and mixed meal tolerance tests (MMTTs) <6 months after diagnosis (n = 80). Multivariable linear regression was utilized. RESULTS: Fasting and area under the curve (AUC) C-peptide from OGTTs (n = 99) at diagnosis and MMTTs (n = 80) after diagnosis were positively associated with BMIZ and age (P < .001 for all). Associations persisted when BMIZ and age were included as independent variables in regression models (P < .001 for all). BMIZ and age explained 31%-47% of the variance of C-peptide measures. In an example, 2 individuals with identical AUC C-peptide values had an approximate 5 fold difference in values after adjustments for BMIZ and age. The association between fasting glucose and C-peptide decreased markedly when fasting C-peptide values were adjusted (r = 0.30, P < .01 to r = 0.07, n.s.). CONCLUSIONS: C peptide measures are strongly and independently related to BMIZ and age at and soon after the diagnosis of T1D. Adjustments for BMIZ and age cause substantial changes in C-peptide values, and impact the association between glycemia and C peptide. Such adjustments can improve assessments of beta-cell impairment at diagnosis. PMID- 29171131 TI - CPAP by helmet for treatment of acute respiratory failure after pediatric liver transplantation. AB - ARF after pediatric liver transplantation accounts for high rate of morbidity and mortality associated with this procedure. The role of CPAP in postoperative period is still unknown. The aim of the study was to describe current practice and risk factors associated with the application of helmet CPAP. In this retrospective observational cohort study, 119 recipients were divided into two groups based on indication to CPAP after extubation. Perioperative variables were studied, and determinants of CPAP application were analyzed in a multivariate logistic model. Sixty patients (60/114) developed ARF and were included in the CPAP group. No differences were found between the two groups for primary disease, graft type, and blood product transfused. At multivariate analysis, weight <11 kg (OR = 2.9; 95% CI = 1.1-7.3; P = .026), PaO2 /FiO2 <380 before extubation (OR = 5.4; 95% CI = 2.1-13.6; P < .001), need of vasopressors (OR = 2.6; 95% CI = 1.1 6.4; P = .038), and positive fluid balance >148 mL/kg (OR = 4.0; 95% CI = 1.6 10.1; P = .004) were the main determinants of CPAP application. In the CPAP group, five patients (8.4%) needed reintubation. Pediatric liver recipients with lower weight, higher need of inotropes/vasopressors, higher positive fluid balance after surgery, and lower PaO2 /FiO2 before extubation were at higher odds of developing ARF needing CPAP application. PMID- 29171132 TI - Structured education to improve primary-care management of headache: how long do the benefits last? A follow-up observational study. AB - BACKGROUND AND PURPOSE: Our earlier study showed that structured education of general practitioners (GPs) improved their practice in headache management. Here the duration of this effect was assessed. METHODS: In a follow-up observational study in southern Estonia, subjects were the same six GPs as previously, managing patients presenting with headache as the main complaint. Data reflecting their practice were collected prospectively during a 1-year period commencing 2 years after the educational intervention. The primary outcome measure was referral rate (RR) to neurological services. Comparisons were made with baseline and post intervention data from the earlier study. RESULTS: In 366 patients consulting during the follow-up period, the RR was 19.9%, lower than at baseline (39.5%; P < 0.0001) or post-intervention (34.7%; P < 0.0001). The RR was diagnosis-dependent: the biggest decline was for migraine. Use of headache diagnostic terms showed changes generally favouring specific terminology. In particular, the proportion of patients given migraine diagnoses greatly increased whilst use of the inappropriate M79.1 (Pericranial) myalgia almost disappeared. Requests for investigations, which had fallen from 26% (of patients seen) at baseline to 4% post-intervention, resurged to 23% (mostly laboratory investigations; requests for X-rays continued to dwindle). Initiation of treatment by the GPs remained at the post-intervention level of just over 80% (up from baseline 58%). CONCLUSIONS: Improvements in GPs' practice after a structured educational programme mostly last for >=3 years, some showing further betterment. A few measures suggest the beginnings of a decline towards baseline levels. This policy-informing evidence for continuing medical education indicates that the educational programme needs repeating every 2-3 years. PMID- 29171133 TI - Nurses' perceptions of preventing falls for patients with dementia in the acute hospital setting. AB - OBJECTIVES: Safe and high-quality care for patients with dementia is a key priority area of the Australian Commission on Safety and Quality in Health Care; however, caring for patients with dementia in the acute hospital setting is perceived as challenging. The aim of this analysis was to explore nurses' perspectives regarding fall prevention for patients with dementia in an acute care setting. METHODS: Secondary analysis of focus group data. Focus groups were conducted with nurses (n = 96) across six hospitals in New South Wales and Victoria. RESULTS: Nurses frequently reported issues relating to the physical environment of the acute care setting, competing priorities in a complex care setting and the need for one-on-one supervision for patients with dementia. CONCLUSION: Nurses report that one-on-one supervision is required to keep patients safe. Future research examining the acceptability and cost-effectiveness of volunteers providing this supervision is warranted in Australian hospitals. PMID- 29171134 TI - Cardiovascular autonomic dysfunction predicts increasing albumin excretion in type 1 diabetes. AB - OBJECTIVE: To determine the potential role of cardiovascular autonomic dysfunction in the development of renal complications in young people with type 1 diabetes (T1D). METHODS: In this prospective study, 199 children and adolescents recruited to the Oxford Regional Prospective Study underwent assessment of autonomic function ~5 years after diagnosis, and were subsequently followed with longitudinal assessments of HbA1c and urine albumin-creatinine ratio (ACR) over 8.6 +/- 3.4 years. Autonomic function was assessed with 4 standardized tests of cardiovascular reflexes: heart rate (HR) response to (1) Valsalva Maneuver, (2) deep breathing, (3) standing, and (4) blood pressure (BP) response to standing. Linear mixed models were used to assess the association between autonomic parameters and future changes in ACR. RESULTS: Independent of HbA1c , each SD increase in HR response to Valsalva Maneuver predicted an ACR increase of 2.16% [95% CI: 0.08; 4.28] per year (P = .04), while each SD increase in diastolic BP response to standing predicted an ACR increase of 2.55% [95% CI: 0.37; 4.77] per year (P = .02). The effect of HR response to standing on ACR reached borderline significance (-2.07% [95% CI: -4.11; 0.01] per year per SD increase, P = .051). CONCLUSIONS: In this cohort of young people with T1D, enhanced cardiovascular reflexes at baseline predicted future increases in ACR. These results support a potential role for autonomic dysfunction in the pathogenesis of diabetic nephropathy. PMID- 29171135 TI - Feasibility and pilot study of an intervention to support active lifestyles in youth with type 1 diabetes: The ActivPals study. AB - BACKGROUND: Evidence suggests youth with type 1 diabetes (T1D) have lower levels of physical activity (PA) than the general population. The ActivPals intervention aimed to support youth with T1D to lead an active lifestyle. METHODS: Twenty youth aged 7 to 16 years with T1D were recruited to a pilot randomized controlled trial. PA and quality of life (QoL) were measured using Actigraph GT3X+ monitor and Pediatric QoL scales at baseline and 1-month follow-up. A two-way, mixed ANOVA showed indicative effects of the intervention. Qualitative interviews were carried out with 16 participants to explore perceptions of the intervention. RESULTS: An increase in moderate to vigorous PA was reported in intervention and control groups from baseline to follow-up (F(1, 14) = 5.83; P = .03), with no significance between group differences. Participants in both groups reported significantly less overall diabetes "problems" (F(1, 16) = 7.93; P = .012) and significantly less lifestyle "problems" (F(1, 16) = 7.39; P = .015) at follow-up. However, both groups also reported significant increases in "problems" with the day-to-day diabetes routine (F(1,16) = 6.48; P = .022) at follow-up. Parents reported significant increased worry about their child's diabetes at follow-up, in both groups (F(1, 14) = 5.83; P = .046). There was no significant increase in reported hypoglycemic occurrences despite increased PA. The qualitative data highlight that goal setting, self-monitoring, and social support were effective motivators for increasing PA. CONCLUSIONS: A larger trial with longer follow-up should be conducted to explore the effect of the intervention on PA in youth with T1D. PMID- 29171136 TI - Prevalence and prognostic impact of electrocardiographic abnormalities in outpatients with extracardiac artery disease. AB - Identifying cardiac disease in patients with extracardiac artery disease (ECAD) is essential for clinical decision-making. Electrocardiography (ECG) is an easily accessible tool to unmask subclinical cardiac disease and to risk stratify patient with or without manifest cardiovascular disease (CV). We aimed to examine the prevalence and prognostic impact of ECG changes in outpatients with ECAD. Outpatients with carotid or lower extremity artery disease (n = 435) and community-based controls (n = 397) underwent resting ECG. The patients were followed during a median of 4.8 years for CV events (hospitalization or death caused by ischaemic heart disease, cardiac arrest, heart failure, or stroke). ECG abnormalities were classified according to the Minnesota Code. Major (33% versus 15%, P<0.001) but not minor ECG abnormalities (23% versus 26%, P = 0.42) were significantly more common in patients versus controls. During the follow-up, 141 patients experienced CV events. Both major ECG abnormalities [hazard ratio (HR) 1.58, 95% confidence interval (CI) 1.11-2.25, P = 0.012] and any ECG abnormalities (HR 1.57, 95% CI 1.06-2.33, P = 0.024) were significantly associated with CV events after adjustment for potential risk factors. In conclusion, ECG abnormalities were common in these outpatients with ECAD. Major and any ECG abnormalities were independent predictors of CV events. Addition of easily accessible ECG information might be useful in risk stratification for such patients. PMID- 29171137 TI - Renewable Methane Generation from Carbon Dioxide and Sunlight. AB - The direct approach: Methane is a potential key player in the world's transition to a more sustainable energy future. The direct conversion of carbon dioxide into methane is highly desirable to lower the concentration of CO2 in the atmosphere and also to store renewable energy. This Highlight describes the first homogeneous system for the light-driven conversion of CO2 into CH4 . PMID- 29171138 TI - Enantioselective Synthesis of N,S-Acetals by an Oxidative Pummerer-Type Transformation using Phase-Transfer Catalysis. AB - Reported is the first enantioselective oxidative Pummerer-type transformation using phase-transfer catalysis to deliver enantioenriched sulfur-bearing heterocycles. This reaction includes the direct oxidation of sulfides to a thionium intermediate, followed by an asymmetric intramolecular nucleophilic addition to form chiral cyclic N,S-acetals with moderate to high enantioselectivites. Deuterium-labelling experiments were performed to identify the stereodiscrimination step of this process. Further analysis of the reaction transition states, by means of multidimensional correlations and DFT calculations, highlight the existence of a set of weak noncovalent interactions between the catalyst and substrate that govern the enantioselectivity of the reaction. PMID- 29171139 TI - Randomized, double-blind, placebo-controlled dose-finding study of the dipeptidyl peptidase-4 inhibitor linagliptin in pediatric patients with type 2 diabetes. AB - OBJECTIVE: To identify the dose of the dipeptidyl peptidase-4 (DPP-4) inhibitor linagliptin in pediatric patients with type 2 diabetes (T2D). METHODS: Double blind, randomized, controlled parallel group study comparing linagliptin 1 and 5 mg once daily, with placebo in 39 patients with T2D aged 10 to below 18 years. The primary efficacy endpoint was the change from baseline in glycated hemoglobin (HbA1c) after 12 weeks of treatment. The key pharmacodynamic endpoint was DPP-4 inhibition during steady-state. RESULTS: Compared to placebo, there was a dose dependent reduction in mean HbA1c of 0.48% and 0.63% with linagliptin 1 and 5 mg, respectively, associated with corresponding declines in mean fasting plasma glucose (FPG) of 5.6 and 34.2 mg/dL. Median DPP-4 inhibition was 38% with linagliptin 1 mg and 79% with linagliptin 5 mg. Geometric mean trough levels of linagliptin were 3.80 and 7.42 nmol/L in the 1 and 5 mg groups, respectively; levels that were slightly higher than in adult patients with T2D that were most likely caused by higher plasma DPP-4 concentrations in the study population. There were no drug-related adverse events during treatment with either dose of linagliptin. CONCLUSIONS: Linagliptin was well tolerated and induced dose dependent DPP-4 inhibition that was accompanied by corresponding reductions in HbA1c and FPG levels in young people with T2D. The results are consistent with the clinical efficacy and safety profile that have been reported for linagliptin in adult patients with T2D, favoring linagliptin 5 mg over 1 mg. PMID- 29171140 TI - Safety and efficacy of autoantigen-specific therapy with 2 doses of alum formulated glutamate decarboxylase in children with multiple islet autoantibodies and risk for type 1 diabetes: A randomized clinical trial. AB - OBJECTIVE: Treatments have failed to delay or stop the autoimmune process, preceding onset of type 1 diabetes. We investigated if autoantigen-specific treatment with alum-formulated glutamate decarboxylase (GAD-Alum) was safe and affected progression to type 1 diabetes in children with islet autoimmunity. METHODS: In an investigator-initiated, double-blind, placebo-controlled clinical trial, non-diabetic children aged 4 to 17.9 years with autoantibodies to glutamate decarboxylase (GADA) and at least one of insulinoma-associated protein 2, insulin or zinc-transporter 8, were randomized, stratified by 2 or >=3 islet autoantibodies, to 2 injections of 20 MUg GAD-Alum or placebo, 30 days apart. Main outcome was safety, investigated by adverse events, hematology, chemistry, thyroid and celiac autoimmunity and titers of islet autoantibodies, and efficacy, investigated by cumulative incidence of diabetes onset over 5-year follow-up. Secondary variables: change in first-phase insulin release (FPIR) after intravenous glucose tolerance tests, fasting, 120 minutes and Area under the curve (AUC) C-peptide and p-glucose after oral glucose tolerance tests and HbA1c. RESULTS: Fifty children (median age: 5.2) were assigned 1:1 to GAD-Alum or placebo, all receiving full treatment and included in the analyses. GAD-Alum did not affect any safety parameter, while GADA titers increased (P = .001). Time to clinical diagnosis was not affected by treatment (hazard ratio, HR = 0.77, P = .574) in the full population or in the separate stratum groups. Treatment did not affect any of the secondary variables. CONCLUSIONS: GAD-Alum as a subcutaneous prime and boost injection was safe in prediabetic young children but did not affect progression to type 1 diabetes. The safety of GAD-Alum should prove useful in future prevention studies. PMID- 29171141 TI - The mental health of adolescents with and without mild/moderate intellectual disabilities in England: Secondary analysis of a longitudinal cohort study. AB - BACKGROUND: Children with mild/moderate intellectual disabilities are at greater risk for mental health problems, with socio-economic factors and adversity partly accounting for this. Fewer data are available for adolescents. METHODS: Secondary analysis was undertaken of the Next Steps annual panel study following a cohort through adolescence into adulthood containing self-report mental health data up to age 16/17. Participants with mild/moderate intellectual disabilities were identified through data linkage with educational records. RESULTS: Adolescents with mild/moderate intellectual disabilities were more likely than non-disabled peers to experience socio-economic disadvantage and bullying. Incidence rates of mental health problems were generally not significantly different between adolescents with and without intellectual disabilities. CONCLUSIONS: These findings are consistent with higher rates of persistent mental health problems beginning earlier among children with intellectual disabilities. Greater attention needs to be paid to the timecourse of mental health problems, and the impact of socio-economic factors, family and peers on mental health. PMID- 29171143 TI - Mechanical effects of negative pressure wound therapy on abdominal wounds - effects of different pressures and wound fillers. AB - The mechanical deformation of the wound edge resulting from negative pressure wound therapy (NPWT) at the standard setting of around -120 mmHg has positive effects in promoting wound healing. However, it may cause pain to the patient during treatment. It is therefore important to study the mechanical effects of the wound edges using lower pressure and different wound fillers. Abdominal wounds were created on eight pigs. The wounds were sealed for NPWT using foam or gauze. Negative pressures between -20 and -160 mmHg were applied, and the decrease in wound diameter and the force with which the edges of the wound were drawn together (wound edge force) were measured. Increasing levels of negative pressure resulted in a gradual decrease in wound diameter and increase in wound edge force and reached a maximum at -120 mmHg, which is the pressure commonly used in clinical practice. Both the decrease in wound diameter and the increase in wound edge force was greater with foam than with gauze. A pressure of -80 mmHg has only 15% less effect than -120 mmHg, while a lower pressure (-40 mmHg) diminished the effects on diameter and force markedly. The NPWT-induced decrease in wound diameter and increase in wound edge force are greater at higher levels of negative pressure and when using foam than when using gauze as a wound filler. It may be possible to tailor the type of wound filler and level of negative pressure to obtain the best balance between wound healing and patient comfort. PMID- 29171142 TI - Interleukin-6 regulates expression of Fos and Jun genes to affect the development of mouse preimplantation embryos. AB - AIM: We investigated whether recombinant mouse interleukin-6 (IL-6) affects the development of preimplantation embryos and induces the -signal transducers and activators of transcription (JAK-STAT) signaling pathway by binding IL-6 signal transducer (IL-6st) and regulating Fos and Jun gene expression, thereby accounting for the negative effect of superovulation on embryo development. METHODS: We compared rates of blastocyst formation from embryos cultured with different concentrations of IL-6 or/and anti-interleukin 6 receptor antibody (anti-IL-6RAb) in superovulated experimental and normal control groups. IL-6 expression in preimplantation embryos was determined by immunofluorescence identification. Fos, Jun and IL-6st messenger RNA expression was detected by PCR and microarray experiments. RESULTS: Rates of blastocyst formation significantly decreased in superovulated embryos, whether or not they were incubated in 0.1, 1, 25 or 50 pg/mL IL-6, (P < 0.01) compared to embryos from naturally ovulated controls, whereas incubation in 5 and 10 pg/mL IL-6 reversed the negative effects of superovulation. The addition of anti-IL-6RAb to naturally ovulated embryos reduced blastocyst rates to those of superovulated embryos. Gene chip analysis indicated that the JAK-STAT signaling pathway contained differentially expressed IL-6, IL-6st, Jun and Fos genes. Both anti-IL-6RAb or ovarian stimulation downregulated IL-6st, Jun, and Fos messenger RNA expression, but expression of the same three genes increased in 5 pg/mL IL-6. CONCLUSION: Ovarian stimulation negatively impacts the development of preimplantation embryos by reducing IL-6 release. IL-6 affects the rate of development of zygotes to blastocyst by regulating IL-6st, Fos and Jun expression in the JAK-STAT signaling pathway. PMID- 29171144 TI - Altered fatty acid-binding protein 4 (FABP4) expression and function in human and animal models of hepatocellular carcinoma. AB - BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related mortality. Risk factors for developing HCC include viral hepatitis, alcohol and obesity. Fatty acid-binding proteins (FABPs) bind long chain free fatty acids (FFAs) and are expressed in a tissue-specific pattern; FABP1 being the predominant hepatic form, and FABP4 the predominant adipocyte form. The aims of this study were to investigate the expression and function of FABPs1-9 in human and animal models of obesity-related HCC. METHODS: FABP1-9 expression was determined in a mouse model of obesity-promoted HCC. Based on these data, expression and function of FABP4 was determined in human HCC cells (HepG2 and HuH7) in vitro. Serum from patients with different underlying hepatic pathologies was analysed for circulating FABP4 levels. RESULTS: Livers from obese mice, independent of tumour status, exhibited increased FABP4 mRNA and protein expression concomitant with elevated serum FABP4. In vitro, FABP4 expression was induced in human HCC cells by FFA treatment, and led to FABP4 release into culture medium. Treatment of HCC cells with exogenous FABP4 significantly increased proliferation and migration of human HCC cells. Patient serum analysis demonstrated significantly increased FABP4 in those with underlying liver disease, particularly non-alcoholic fatty liver disease (NAFLD) and HCC. CONCLUSIONS: These data suggest FABP4, an FABP not normally expressed in the liver, can be synthesized and secreted by hepatocytes and HCC cells, and that FABP4 may play a role in regulating tumour progression in the underlying setting of obesity. PMID- 29171145 TI - Acute care nurses' views on family participation and collaboration in fundamental care. AB - AIMS AND OBJECTIVES: To understand the beliefs, attitudes and perceptions of nurses regarding family participation and collaboration in the care of their hospitalized adult relative. BACKGROUND: Family participation in care is known to enhance the quality of patient care. Nurses are uniquely placed to support such participation, including the delivery of fundamental care. However, nurses' attitudes and beliefs may help or hinder participation. DESIGN: A mixed methods approach with an exploratory sequential design was used. SETTING: A regional referral hospital in Australia. PARTICIPANTS: Nurses were eligible to participate in the study if they were permanent staff of the hospital, and who in their day to-day work had direct contact with adult patients and their families on acute care wards. METHODS: Observer-as-participant observation data and semi-structured interviews were undertaken. 30 hr of observational data were gathered, and 14 nurses were interviewed. Data collection occurred between September and December 2016. Following separate analysis, data were triangulated. RESULTS: Analysis uncovered two contrasting categories: (i) enacting family participation (four themes); and (ii) hindering family participation (five themes). CONCLUSION: The findings of our study demonstrated that the practices of nurses do not always align with healthcare policies, and strategies to support nurses to enact patient and family-centred practices are needed. RELEVANCE TO CLINICAL PRACTICE: Nurses can use these findings to make informed evidence-based changes to the way they practice and communicate with families to ensure fundamental care is delivered. PMID- 29171146 TI - OnabotulinumtoxinA in chronic migraine: predictors of response. A prospective multicentre descriptive study. AB - BACKGROUND AND PURPOSE: OnabotulinumtoxinA is a treatment specifically approved for the prophylaxis of chronic migraine in adults. The aim of this study was to assess the effectiveness of OnabotulinumtoxinA in chronic migraine after 1 year of treatment in a real-life setting and to identify clinical predictors of outcome. METHODS: We designed a prospective multicentre study performed in 13 hospitals in Spain. Patients underwent a complete medical history and examination. They were treated with OnabotulinumtoxinA every 12 weeks for 1 year. Data about outcome, adverse events, abortive medication use, emergency room use and disability were collected at 3 and 12 months. RESULTS: A total of 725 subjects completed the study. At 12 months, 79.3% showed >50% reduction in number of headaches per month and 94.9% reported no adverse events. Unilaterality of pain, fewer days of disability per month and milder headache at baseline were correlated with good outcome. Duration of disease <12 months increased the chances of response to treatment with OnabotulinumtoxinA (odds ratio, 1.470; 95% confidence interval, 1.123-2.174; P = 0.045). CONCLUSIONS: This study confirmed the effectiveness of treatment with OnabotulinumtoxinA after 1 year of treatment. The chances of a good outcome may be increased by starting treatment in the first 12 months after chronic migraine diagnosis. PMID- 29171147 TI - Physical activity perceptions and behaviors among young adults with congenital heart disease: A mixed-methods study. AB - OBJECTIVE: A physically active lifestyle can help maintain positive physical and psychosocial health outcomes among adults with congenital heart disease (CHD). This study explored the physical activity perceptions and behaviors among young adults with CHD. DESIGN: This was a cross-sectional, mixed-methods study that included objectively measured physical activity assessment (accelerometer), individual semistructured interviews, and psychosocial questionnaires. RESULTS: Fifteen participants (67% male; 21 +/- 3 years old) with moderate (n = 10) or complex (n = 5) CHD were recruited from an outpatient adult CHD clinic. Participants accumulated 26 +/- 16 minutes of moderate-to-vigorous physical activity per day, and reported a high quality of life, moderate self-efficacy for exercise, and low cardiac-focused anxiety. Qualitative data indicated that participants reported more positive perceptions toward activity if their family members encouraged physical activity participation, including siblings that engaged in physical activity alongside participants. Participants described parents as supportive rather than overprotective. Activity precautions were perceived by participants as being instructions from cardiologists rather than restrictions by parents. Participants described some physical limitations compared to peers, but managed challenges by either working within their limitations or choosing activities that met their expectations and/or in which they could fully participate. Participants often described childhood physical activity in the context of school, physical education, and organized sports. Whereas physical activity in childhood was viewed as recreational, the cardiac health-promoting aspects became more prominent in adulthood. Activities performed during one's employment were considered sufficient to meet physical activity recommendation levels, and participants reported limited time and/or energy to participate in activity outside of work. CONCLUSIONS: The influence of family appeared to help participants adopt a positive perception toward activity participation in childhood that was carried forward to young adulthood. Future clinical work should target adolescents with CHD with less social supports and/or negative perceptions toward physical activity. PMID- 29171148 TI - Comorbidity and the increased mortality after hospitalization for stroke: a population-based cohort study. AB - : Essentials Comorbidity is prevalent in the stroke population and affects post stroke survival. A stroke patient cohort (n = 201 691) and a general population cohort were followed for survival. Cancer and advanced renal/liver disease substantially increased one-year stroke mortality. Tailoring stroke interventions according to comorbidity may reduce excess mortality. SUMMARY: Background Comorbidity is prevalent among stroke patients, affecting post-stroke survival. It remains unknown whether comorbidity impacts post-stroke mortality beyond the combined individual effects of stroke and comorbidity. Methods Using nationwide Danish databases, we performed a cohort study of 201 691 patients >= 18 years old with incident ischemic stroke, intracerebral or subarachnoid hemorrhage, or unspecified stroke during 1995-2012, and 992 942 adults from the general population, matched to stroke patients by birth year, sex and individual comorbidities in the Charlson Comorbidity Index. During up to 5 years of follow up, we computed standardized mortality rates (SMRs) to assess interaction contrasts as a measure of excess mortality not explained by the additive effects of stroke and comorbidity acting alone. Results Five-year post-stroke mortality was 48%, corresponding to an SMR of 187 deaths per 1000 person-years. During the 30-day peak post-stroke mortality (SMR, 180 per 1000 person-months), interaction with comorbidity represented 23%, 34% and 51% of post-stroke mortality rates among patients with low (score = 1), moderate (score = 2-3) and high (score = 4+) comorbidity based on Charlson Comorbidity Index scores. The interaction accounted for 5% to 32% of subsequent 31-365-day post-stroke mortality rates, depending on comorbidity level. The interaction contrasts were most notable among comorbid patients with cancer, particularly with hematological or metastatic disease, followed by patients with moderate-to-severe liver or renal disease. Conclusion Comorbidity, notably cancer and advanced renal or liver disease, increased 1-year mortality after stroke beyond the combined effects expected from either disease acting alone.

AB - Emerging evidence suggests that maternal prepregnancy body mass index or weight (MPBW) may be associated with offspring's blood pressure (BP). Therefore, we conducted a systematic review-following the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement-to assess and judge the evidence for an association between MPBW with offspring's later BP. Five data bases were searched without limits. Risk of bias was assessed using the "Tool to Assess Risk of Bias in Cohort Studies," and an evidence grade was allocated following the World Cancer Research Fund criteria. Of 2,011 publications retrieved, 16 studies (all cohort studies) were included in the systematic review; thereof, 5 studies (31%) were rated as good-quality studies. Overall, data from 63,959 participants were enclosed. Systolic BP was analysed in 15 (5 good quality), diastolic BP in 12 (3 good quality), and mean arterial pressure in 3 (no good quality) studies. Five good-quality studies of MPBW with offspring's systolic BP as the outcome and 1 good-quality study with offspring's diastolic BP as the outcome observed a significant association. However, after adding offspring's anthropometry variables to the statistical model, the effect attenuated in 4 studies with systolic BP to nonsignificance, the study with diastolic BP remained significant. No good-quality studies were found with respect to offspring's later mean arterial pressure. In conclusion, this systematic review found suggestive, but still limited, evidence for an association between MPBW with offspring's later BP. The available data suggest that the effect might be mainly mediated via offspring's anthropometry.

AB - Innovative techniques to visualize native microRNAs (miRNAs) in live cells can dramatically impact current research on the roles of miRNA in biology and medicine. Here, we report a novel approach for live-cell miRNA imaging using a biodegradable MnO2 nanosheet-mediated DD-A FRET hybridization chain reaction (HCR). The MnO2 nanosheets can adsorb DNA hairpin probes and deliver them into live cells. After entering cells, the MnO2 nanosheets are degraded by cellular GSH. Then, the target miR-21 triggers cascaded assembly of the liberated hairpin probes into long dsDNA polymers, which brings each two FAMs (donor) and one TAMRA (acceptor) into close proximity to generate significantly enhanced DD-A FRET signals, which was discovered and proven by our previous report. We think the developed approach can serve as an excellent intracellular miRNAs detection tool, which promises the potential for biological and disease studies.

PMID- 29171152 TI - Evaluation of three experimental in vitro models for the assessment of the mechanical cleansing efficacy of wound irrigation solutions. AB - The aim of this study was to compare different wound-rinsing solutions to determine differences in the efficiency and to evaluate three different in vitro models for wound cleansing. Different wound-rinsing solutions (physiological saline solution, ringer lactate solution for wound irrigation, water and a solution containing polihexanide and the surfactant undecylenamidopropyl-betain) were applied on standardised test models (one- and three-chamber model, flow-cell method and a biofilm model), each challenged with three different standardised wound test soils. In the one-chamber model saline showed a better effect on decontaminating proteins than the ringer lactate solution. In the flow-cell method, water performed better than physiological saline solution, whereas ringer lactate solution demonstrated the lowest cleansing effect. No obvious superiority between the two electrolyte-containing solutions was detectable in the biofilm model. Unfortunately, it was not possible to assess the protein decontamination qualities of the surfactant-containing solution because of the interference with the protein measurement. The flow-cell method was able to detect differences between different rinse solutions because it works at constant flow mechanics, imitating a wound-rinsing procedure. The three-chamber and the less-pronounced modified one-chamber method as well as the biofilm model had generated inhomogeneous results. PMID- 29171154 TI - Layperson's perception of axial midline angulation in asymmetric faces. AB - OBJECTIVE: Asymmetric facial features such as a deviated nose and chin are common and known to affect smile esthetics. When presented with these asymmetries, the clinician must consider the impact they will have on the smile design parameters especially the placement and angulation of the dental midline, which is a common starting point for a case involving smile design. The purpose of this article is to determine if the nose and chin deviations affect the perception of dental midline angulation. MATERIALS AND METHODS: An asymmetric facial model (AFM) was created from a digital symmetric facial model, used in a previous study by digitally deviating the nose and chin to the same side. Eight different pictures of this AFM were created, each with different degrees of maxillary midline angulation (both in and against the direction of the deviated nose and chin). Using a visual Likert scaled delivered via Websurvey in the private practice setting, one hundred and ninety-six randomly selected laypersons were asked to evaluate each image according to their own notions of beauty. RESULTS: A minor axial dental midline angulation of 3.5 degrees can be perceived independently of the direction of the cant. All pictures where the midline was canted pointing in the opposite direction of nose and chin deviations presented lower rating mean values. CONCLUSIONS: Off-center noses and chins can influence the perceived attractiveness of a smile with a canted dental midline. The degree and direction of a canted midline can influence the harmony between the smile and overall face, with canting in the same direction of the asymmetric features being rated as more attractive. CLINICAL SIGNIFICANCE: The dental midline should be as vertically straight as possible. If a midline cant is present, however, it is more favorable to have a dental midline angulation which points in the same direction as nose and chin deviations, rather than in the opposite direction. PMID- 29171155 TI - Interactions of (2S,6S;2R,6R)-Hydroxynorketamine, a Secondary Metabolite of (R,S) Ketamine, with Morphine. AB - Ketamine and its primary metabolite norketamine attenuate morphine tolerance by antagonising N-methyl-d-aspartate (NMDA) receptors. Ketamine is extensively metabolized to several other metabolites. The major secondary metabolite (2S,6S;2R,6R)-hydroxynorketamine (6-hydroxynorketamine) is not an NMDA antagonist. However, it may modulate nociception through negative allosteric modulation of alpha7 nicotinic acetylcholine receptors. We studied whether 6 hydroxynorketamine could affect nociception or the effects of morphine in acute or chronic administration settings. Male Sprague Dawley rats received subcutaneous 6-hydroxynorketamine or ketamine alone or in combination with morphine, as a cotreatment during induction of morphine tolerance, and after the development of tolerance induced by subcutaneous minipumps administering 9.6 mg morphine daily. Tail flick, hot plate, paw pressure and rotarod tests were used. Brain and serum drug concentrations were quantified with high-performance liquid chromatography-tandem mass spectrometry. Ketamine (10 mg/kg), but not 6 hydroxynorketamine (10 and 30 mg/kg), enhanced antinociception and decreased rotarod performance following acute administration either alone or combined with morphine. Ketamine efficiently attenuated morphine tolerance. Acutely administered 6-hydroxynorketamine increased the brain concentration of morphine (by 60%), and brain and serum concentrations of 6-hydroxynorketamine were doubled by morphine pre-treatment. This pharmacokinetic interaction did not, however, lead to altered morphine tolerance. Co-administration of 6-hydroxynorketamine 20 mg/kg twice daily did not influence development of morphine tolerance. Even though morphine and 6-hydroxynorketamine brain concentrations were increased after co-administration, the pharmacokinetic interaction had no effect on acute morphine nociception or tolerance. These results indicate that 6 hydroxynorketamine does not have antinociceptive properties or attenuate opioid tolerance in a similar way as ketamine. PMID- 29171156 TI - The roles of CSFs on the functional polarization of tumor-associated macrophages. AB - Macrophages have a central role in numerous physiological processes, such as immune defense, maintenance of tissue homeostasis, wound healing, and inflammation. Moreover, in numerous severe disorders, such as cancer or chronic inflammation, their functions can be profoundly affected. Macrophages continuously sense their environment and adapt their phenotypes and functions to the local requirements; this process is called plasticity. In addition to stress signals, metabolites, and direct cell-contact interactions with surrounding cells, numerous cytokines play a central role in controlling macrophage polarization. In this review, we will focus on three human macrophage differentiation factors: macrophage colony-stimulating factor (M-CSF), IL-34, and granulocyte M-CSF. These CSFs allow human monocyte survival, promote their differentiation into macrophages, and control macrophage polarization as they give rise to cells with different phenotype and functions. Based on recent observations, the role of granulocyte CSF on macrophage polarization is also addressed. Finally, our current knowledge on the expression of these growth factors in tumor microenvironment and their impact on the generation and polarization of tumor-associated macrophages are summarized. PMID- 29171157 TI - Bioavailability of Terpenes and Postprandial Effect on Human Antioxidant Potential. An Open-Label Study in Healthy Subjects. AB - SCOPE: To assess bioavailability of terpenes in human plasma and their effect on oxidative stress biomarkers. METHODS AND RESULTS: In this open-label and single arm postprandial trial, seventeen healthy male volunteers (20-40 years old) follow a low-phytochemical diet for 5 days. Next, after overnight fasting, volunteers consume Mastiha powder (a natural resin rich in terpenes) dispersed in water. Blood samples are collected on time points 0 h (before ingestion) and 0.5, 1, 2, 4, 6, and 24 h (post-ingestion). Ultra-high-pressure liquid chromatography high-resolution MS (UHPLC-HRMS/MS) is applied for high throughput analysis of plasma. Serum resistance to oxidation and oxidized LDL (oxLDL) levels are measured. UHPLC-HRMS/MS analysis shows that major terpenes are bioavailable since 0.5 h after administration, reaching a peak between 2 h and 4 h. Serum resistance to oxidation, expressed as difference of tLAG (time point-0 h), starts to increase from 0.5 h. This increase reaches statistical significance at 4 h (402.3 +/- 65.0 s), peaks at 6 h (524.6 +/- 62.9 s), and remains statistically significant until 24 h (424.2 +/- 48.0 s). oxLDL levels, expressed as %change from 0 h, are reduced significantly from time point-1 h until time point-6 h. CONCLUSION: Results demonstrate the terpene bioavailability pattern after oral administration of Mastiha. Terpenes are potential mediators of antioxidant defense in vivo. PMID- 29171158 TI - Genetic monitoring of open ocean biodiversity: An evaluation of DNA metabarcoding for processing continuous plankton recorder samples. AB - DNA metabarcoding is an efficient method for measuring biodiversity, but the process of initiating long-term DNA-based monitoring programmes, or integrating with conventional programs, is only starting. In marine ecosystems, plankton surveys using the continuous plankton recorder (CPR) have characterized biodiversity along transects covering millions of kilometres with time-series spanning decades. We investigated the potential for use of metabarcoding in CPR surveys. Samples (n = 53) were collected in two Southern Ocean transects and metazoans identified using standard microscopic methods and by high-throughput sequencing of a cytochrome c oxidase subunit I marker. DNA increased the number of metazoan species identified and provided high-resolution taxonomy of groups problematic in conventional surveys (e.g., larval echinoderms and hydrozoans). Metabarcoding also generally produced more detections than microscopy, but this sensitivity may make cross-contamination during sampling a problem. In some samples, the prevalence of DNA from large plankton such as krill masked the presence of smaller species. We investigated adding a fixed amount of exogenous DNA to samples as an internal control to allow determination of relative plankton biomass. Overall, the metabarcoding data represent a substantial shift in perspective, making direct integration into current long-term time-series challenging. We discuss a number of hurdles that exist for progressing DNA metabarcoding from the current snapshot studies to the requirements of a long term monitoring programme. Given the power and continually increasing efficiency of metabarcoding, it is almost certain this approach will play an important role in future plankton monitoring. PMID- 29171159 TI - Unilateral pectoralis major muscle flap for the treatment of sternal wounds due to Ludwig's angina. AB - Necrotising descending mediastinitis may rarely originate from Ludwig's angina, which is an infection of the submandibular space. The use of the bilateral pectoralis major muscle flap for the treatment of sternal wound dehiscence is common, but reports of the unilateral application of this flap are scarce. This study aims to report the use of the unilateral pectoralis major muscle flap for the treatment of sternotomy dehiscence in a patient with mediastinitis due to Ludwig's angina. A 21-year-old male patient underwent an exploratory cervicotomy and median sternotomy for drainage of a submandibular infection that extended to the anterior, retropharyngeal and mediastinal cervical spaces. The patient had dehiscence of the sternal wound, and the unilateral pectoralis major muscle flap was used for reconstruction of the defect. This flap was able to completely cover the area of dehiscence of the sternotomy, and the patient presented a good postoperative evolution, without complications. The reconstruction technique using the unilateral pectoralis major muscle flap was considered a good option for the treatment of sternotomy dehiscence. It is an adjuvant method in the treatment of infections such as mediastinitis and osteomyelitis of the sternum secondary to Ludwig's angina, allowing a stable coverage of the sternum. PMID- 29171160 TI - Joining the dots between omics and environmental management. AB - With the rapid advancement of DNA sequencing technologies and the substantial reduction of their running costs, environmental genomics and transcriptomics become more affordable and popular in environmental toxicology. In parallel, there are also speedy improvements of mass spectrometry and nuclear magnetic resonance spectrometry, enabling high-throughput analyses of proteins and metabolites in biological samples and promoting research studies in proteomics and metabolomics. By applying these high-throughput omics technologies, researchers can quickly generate an unprecedentedly vast amount of biological data that may be useful to environmental management. However, the current pace of applying omics information in environmental management is still very slow, and lags well behind the rapid development of omics-based research. This timely commentary, therefore, calls for joint efforts to increase this pace and join the dots between omics and environmental management, turning omics into practical tools. Herein, I explore how omics can contribute to risk assessment and management of chemicals, and recommend what we can do to facilitate and promote the use of omics information in environmental management.

(c) 2017 SETAC. PMID- 29171161 TI - Negative pressure wound therapy in complex cranio-maxillofacial and cervical wounds. AB - The care and the management of the healing of difficult wounds at the level of the skull-facial face many problems related to patient compliance and the need to perform multiple dressings, with long periods of healing and, occasionally, a very long hospitalisation period. The introduction and evolution of negative pressure wound therapy (NPWT) in the treatment of difficult wounds has resulted in better healing, with a drastic reduction in terms of time and biological costs to the patient and cost to the health care system. The main aim of this study is to describe and discuss, using out our experience, the usefulness of NPWT in the cranial-facial-cervical region. We studied 16 patients with complex wounds of the cranial-facial-cervical region treated with NPWT. We divided clinical cases in four groups: cervicofacial infectious disease, healing complications in oncological-reconstructive surgery, healing complications of injury with exposure of bone and/or internal fixations and healing complications in traumatic injury with loss of substance. We evaluated complete or incomplete wound healing; application time, related also to hospitalisation time; days of intensive care unit (ICU) stay; management of the upper airways; timing of medication renewal; and patient comfort and compliance (on a scale of 1-5). Depression values were always between -75 and -125 mmHg in a continuous aspiration pattern. For every patient, we used the ActiVAC Therapy Unit, derived from the vacuum-assisted closure system (Kinetic Concepts Inc., San Antonio, TX). Medication renewals were performed every 48-72 hours. The NPWT application time ranged from 4 to 22 days (mean of 11.57 day). Therapy was effective to gain a complete restitutio ad integrum in every patient included in the group of cervicofacial infectious disease. Therapy has, however, been well tolerated in our series; this is probably due to the decreased number of applications, the ease of use and the comfort of the system relative to traditional dressing. Results were satisfactory for most of cases treated; faster and more effective wound healing was achieved. The lower number of NPWT applications, relating to standard dressings, led to an increase in patient comfort and compliance and a decrease in the use of medical, and in some cases economic, resources according to international literature.

AB - CHARGE syndrome is a multiple congenital anomaly condition caused, in a majority of individuals, by loss of function pathogenic variants in the gene CHD7. In this special issue of the American Journal of Medical Genetics part C, authors of eleven manuscripts describe specific organ system features of CHARGE syndrome, with a focus on recent developments in diagnosis, etiologies, and treatments. Since 2004, when CHD7 was identified as the major causative gene in CHARGE, several animal models (mice, zebrafish, flies, and frog) and cell-based systems have been developed to explore the underlying pathophysiology of this condition. In this article, we summarize those advances, highlight opportunities for new discoveries, and encourage readers to explore specific organ systems in more detail in each individual article. We hope the excitement around innovative research and development in CHARGE syndrome will encourage others to join this effort, and will stimulate other investigators and professionals to engage with individuals diagnosed as having CHARGE syndrome, their families, and their care providers. PMID- 29171163 TI - Surface changes of various bulk-fill resin-based composites after exposure to different food-simulating liquid and beverages. AB - OBJECTIVE: To evaluate surface roughness, hardness, and morphology changes of various bulk-fill resin composites eroded by different food-simulating liquids and beverages. MATERIALS AND METHODS: One hundred and thirteen specimens were fabricated in polytetrafluoroethylene cylindrical mold (10 mm in diameter and 4 mm in thickness). Before immersion, baseline data of roughness, Vicker's microhardness were recorded and surface characteristics were examined using scanning electron microscopy (SEM). Each product of specimens (SDR, Dentsply; SonicFill, Kerr; Tetric N-Ceram Bulk Fill, Ivoclar Vivadent AG; and Filtek Bulk Fill, 3M ESPE) were divided into 5 groups for spicy and sour soup, spicy soup (Tom Yum), pineapple juice, passionfruit juice, and deionized water (served as a control). Specimens were then alternately immersed in storage agents for 5 seconds and artificial saliva for 5 seconds over 10 cycles. Specimens were stored in artificial saliva for 22 hours. This process was repeated for 28 days. After immersion, surface hardness and roughness of specimens were evaluated at 7, 14, 21, and 28 days and data were analyzed by two-way repeated ANOVA and Tukey's HSD (alpha = 0.05). Surface morphology of specimens was also examined on day 28. RESULTS: The SDR group had the most statistically significant decrement in hardness (25.65 +/- 1.74 kg/mm2 in mean difference) and increment in roughness (0.26 +/- 0.10 MUm in mean difference; P < .05). Passionfruit juice caused the most surface changes in bulk-fill resin composites. SEM photomicrographs showed surface changes of all resin composites in varying degrees. CONCLUSION: Acidic food-simulating liquids and beverages significantly increased the surface roughness and decreased surface microhardness of bulk-fill resin composites after evaluation at the end of the 28-day immersion period. CLINICAL SIGNIFICANCE: For restoration of the affected teeth in patients who consume acidic food and beverages, roughness and erosion of resin composites should be considered. All of bulk-fill resin-based composites except SDR may be suitable for restorations in these patients. PMID- 29171165 TI - ReadTools: A universal toolkit for handling sequence data from different sequencing platforms. AB - Sequencing whole genomes has become a standard research tool in many disciplines including Molecular Ecology, but the rapid technological advances in combination with several competing platforms have resulted in a confusing diversity of formats. This lack of standard formats causes several problems, such as undocumented preprocessing steps or the loss of information in downstream software tools, which do not account for the specifics of the different available formats. ReadTools is an open-source Java toolkit designed to standardize and preprocess read data from different platforms. It manages FASTQ- and SAM formatted inputs while dealing with platform-specific peculiarities and provides a standard SAM compliant output.

PMID- 29171164 TI - Exercise performance, haemodynamics, and respiratory pattern do not identify heart failure patients who end exercise with dyspnoea from those with fatigue. AB - AIMS: The two main symptoms referred by chronic heart failure (HF) patients as the causes of exercise termination during maximal cardiopulmonary exercise testing (CPET) are muscular fatigue and dyspnoea. So far, a physiological explanation why some HF patients end exercise because of dyspnoea and others because of fatigue is not available. We assessed whether patients referring dyspnoea or muscular fatigue may be distinguished by different ventilator or haemodynamic behaviours during exercise. METHODS AND RESULTS: We analysed exercise data of 170 consecutive HF patients with reduced left ventricular ejection fraction in stable clinical condition. All patients underwent maximal CPET and a second maximal CPET with measurement of cardiac output by inert gas rebreathing at peak exercise. Thirty-eight (age 65.0 +/- 11.1 years) and 132 (65.1 +/- 11.4 years) patients terminated CPET because of dyspnoea and fatigue, respectively. Haemodynamic and cardiorespiratory parameters were the same in fatigue and dyspnoea patients. VO2 was 10.4 +/- 3.2 and 10.5 +/- 3.3 mL/min/kg at the anaerobic threshold and 15.5 +/- 4.8 and 15.4 +/- 4.3 at peak, in fatigue and dyspnoea patients, respectively. In fatigue and dyspnoea patients, peak heart rate was 110 +/- 22 and 114 +/- 22 beats/min, and VE/VCO2 and VO2 /work relationship slopes were 31.2 +/- 6.8 and 30.6 +/- 8.2 and 10.6 +/- 4.2 and 11.4 +/- 5.5 L/min/W, respectively. Peak cardiac output was 6.68 +/- 2.51 and 6.21 +/- 2.55 L/min (P = NS for all). CONCLUSIONS: In chronic HF patients in stable clinical condition, fatigue and dyspnoea as reasons of exercise termination do not highlight different ventilatory or haemodynamic patterns during effort. PMID- 29171166 TI - Outcomes of Asian patients with localized prostate cancer treated with combined intensity modulated radiation therapy (IMRT) and high dose rate (HDR) brachytherapy: A single institution experience. AB - AIM: External beam radiotherapy (EBRT) followed by high dose rate (HDR) brachytherapy boost has demonstrated minimal toxicities and improved disease control rate compared with EBRT alone in observational and randomized studies with predominantly Caucasian patients. This study aims to report the outcomes of patients treated with this approach in our predominantly Asian population. METHODS: Medical records for patients with localized prostate cancer who received combined EBRT delivered via intensity modulated radiotherapy (IMRT) technique followed by HDR brachytherapy boost were retrospectively reviewed. Outcomes evaluated included 5-year biochemical recurrence-free survival (per Phoenix definition), overall survival and treatment toxicities. RESULTS: From June 2009 to March 2015, 75 patients were treated with IMRT followed by HDR brachytherapy boost. Twenty patients (27%) had intermediate risk, 55 (74%) had high-risk disease. Median follow up was 64 months. All patients received IMRT to a median dose of 45 Gy to the pelvis followed by HDR brachytherapy boost. Sixty, 10 and 5 patients received boost of 21 Gy in two fractions, 19 Gy in two fractions and 15 Gy in a single fraction, respectively. All patients met the planning criteria adapted from RTOG 0815. The 5-year prostate-specific antigen (PSA) control was 85.2% (80.3% and 100% for high-risk and intermediate-risk group, respectively). Cancer-specific survival and overall survival are 97.3% and 92.0%, respectively. Eleven (15%) patients developed biochemical failure, six of which had distant metastasis. Three (4%) developed grade 3 genitourinary toxicity (urethral stricture and/or cystitis) and none developed grade 3 radiation proctitis. CONCLUSION: Our outcomes are comparable to internationally published data and demonstrate reproducibility of this approach in our population. PMID- 29171167 TI - A clinical study comparing digital radiography and near-infrared transillumination in caries detection. AB - OBJECTIVE: The purpose of this study was to compare the effectiveness of detecting proximal carious lesions utilizing a new near-infrared transillumination (NIRTI) system (CariVu, Dexis) to traditional digital bitewing radiography (BWXR). MATERIALS AND METHODS: Thirty patients received four posterior BWXRs and all premolars and molars were individually imaged with the NIRTI device. Sixty-seven proximal carious lesions were classified based on their depth into enamel or dentin for both BWXR and NIRTI images. RESULTS: The caries depth classification between the two systems were strongly correlated (rs = 0.66; Spearman range: 0.60-0.79 = strong) and significant (P < .001) with a median score of 3 for NIRTI and 2 for BWXR. CONCLUSIONS: The new NIRTI system (CariVu) may serve as an adjunct to BWXR in the diagnosis of proximal caries. CLINICAL SIGNIFICANCE: The NIRTI system could serve as an adjunct diagnostic system that could be used in high-caries risk programs where patients are closely monitored with regimented follow-up appointments. NIRTI could also be beneficial with pregnant or pediatric patients, and in situations where radiography may not be available such as remote humanitarian missions. PMID- 29171168 TI - Pilocytic astrocytoma with leptomeningeal spread in a patient with incontinentia pigmenti presenting with unilateral nystagmus. AB - Incontinentia pigmenti (IP) is a genetic disorder caused by mutations in IKBKG, leading to functional loss of nuclear factor kappa B (NF-KB). We report the case of a 6-month-old female child with IP who presented with unilateral nystagmus and was found to have a pilocytic astrocytoma with leptomeningeal spread. Enhanced understanding of the relationship between NF-KB, along with its upstream regulators, and tumorigenesis may shed light on whether a subset of patients with IP may be at increased risk for neoplasia. PMID- 29171169 TI - No effect of transcranial direct current stimulation of the dorsolateral prefrontal cortex on short-term memory. AB - INTRODUCTION: Short-term memory refers to the capacity for holding information in mind for a short period of time with conscious memorization. It is an important ability for daily life and is impaired in several neurological and psychiatric disorders. Anodal transcranial direct current stimulation (tDCS) applied to the dorsolateral prefrontal cortex (DLPFC) was reported to enhance the capability of short-term memory in healthy subjects. However, results were not consistent and what is the possible impact factor is not known. One important factor that may significantly influence the effect of tDCS is the timing of tDCS administration. AIMS: In order to explore whether tDCS impact short-term memory and the optimal timing of tDCS administration, we applied anodal tDCS to the left DLPFC to explore the modulatory effect of online and off-line tDCS on digit span as well as visual short-term memory performance in healthy subjects. RESULTS: Results showed tDCS of the left DLPFC did not influence intentional digit span memory performance, whether before the task or during the task. In addition, tDCS of the DLPFC administered before the task showed no effect on visual short-term memory, while there was a trend of increase in false alarm when tDCS of the DLPFC administered during the task. CONCLUSIONS: These results did not provide evidence for the enhancement of short-term memory by tDCS of the left DLPFC in healthy subjects, but it suggested an importance of administration time for visual short term memory. Further studies are required to taking into account the baseline performance of subjects and time-dependence feature of tDCS. PMID- 29171170 TI - Reestablishment of individual sleep structure during a single 14-h recovery sleep episode after 58 h of wakefulness. AB - Sleep structure is highly stable within individuals but different between individuals. The present study investigated robustness of the individual sleep structure to extended total sleep deprivation. Seventeen healthy men spent a baseline night (23:00-07:00 hours), 58 h of sleep deprivation and a 14-h recovery night (17:00-07:00 hours) in the laboratory. Intraclass correlation coefficients showed that the agreement between baseline and recovery with respect to the proportion of the different sleep stages increased as a function of recovery sleep duration. High values were reached for most of the sleep stages at the end of 14 h of recovery sleep (intraclass correlation coefficients between 0.38 and 0.76). If sleep duration of the recovery night is extended to 14 h, sleep stage distribution resembles that of a baseline night underlining the robustness of the individual sleep structure. PMID- 29171171 TI - Sleep restriction and cognitive load affect performance on a simulated marksmanship task. AB - Sleep restriction degrades cognitive and motor performance, which can adversely impact job performance and increase the risk of accidents. Military personnel are prone to operating under sleep restriction, and previous work suggests that military marksmanship may be negatively affected under such conditions. Results of these studies, however, are mixed and have often incorporated additional stressors (e.g. energy restriction) beyond sleep restriction. Moreover, few studies have investigated how the degree of difficulty of a marksmanship task impacts performance following sleep restriction. The purpose of the current experiment was to study the effects of sleep restriction on marksmanship while minimizing the potential influence of other forms of stress. A friend-foe discrimination challenge with greater or lesser degrees of complexity (high versus low load) was used as the primary marksmanship task. Active duty Soldiers were recruited, and allowed 2 h of sleep every 24 h over a 72-h testing period. Marksmanship tasks, cognitive assessment metrics and the NASA-Task Load Index were administered daily. Results indicated that reaction times to shoot foe targets and signal friendly targets slowed over time. In addition, the ability to correctly discriminate between friend and foe targets significantly decreased in the high-cognitive-load condition over time despite shot accuracy remaining stable. The NASA-Task Load Index revealed that, although marksmanship performance degraded, participants believed their performance did not change over time. These results further characterize the consequences of sleep restriction on marksmanship performance and the perception of performance, and reinforce the importance of adequate sleep among service members when feasible. PMID- 29171172 TI - Cost-effectiveness of routine viral load monitoring in low- and middle-income countries: a systematic review. AB - INTRODUCTION: Routine viral load monitoring for HIV-1 management of persons on antiretroviral therapy (ART) has been recommended by the World Health Organization (WHO) to identify treatment failure. However, viral load testing represents a substantial cost in resource constrained health care systems. The central challenge is whether and how viral load monitoring may be delivered such that it maximizes health gains across the population for the costs incurred. We hypothesized that key features of program design and delivery costs drive the cost-effectiveness of viral load monitoring within programs. METHODS: We conducted a systematic review of studies on the cost-effectiveness of viral load monitoring in low- and middle-income countries (LMICs). We followed the Cochrane Collaboration guidelines and the PRISMA reporting guidelines. RESULTS AND DISCUSSION: We identified 18 studies that evaluated the cost-effectiveness of viral load monitoring in HIV treatment programs. Overall, we identified three key factors that make it more likely for viral load monitoring to be cost-effective: 1) Use of effective, lower cost approaches to viral load monitoring (e.g. use of dried blood spots); 2) Ensuring the pathway to health improvement is established and that viral load results are acted upon; and 3) Viral load results are used to simplify HIV care in patients with viral suppression (i.e. differentiated care, with fewer clinic visits and longer prescriptions). Within the context of differentiated care, viral load monitoring has the potential to double the health gains and be cost saving compared to the current standard (CD4 monitoring). CONCLUSIONS: The cost-effectiveness of viral load monitoring critically depends on how it is delivered and the program context. Viral load monitoring as part of differentiated HIV care is likely to be cost-effective. Viral load monitoring in differentiated care programs provides evidence that reduced clinical engagement, where appropriate, is not impacting health outcomes. Introducing viral load monitoring without differentiated care is unlikely to be cost-effective in most settings and results in lost opportunity for health gains through alternative uses of limited resources. As countries scale up differentiated care programs, data on viral suppression outcomes and costs should be collected to evaluate the on-going cost-effectiveness of viral load monitoring as utilized in practice.

AB - Through this brief review, we provide a comprehensive historical background of the development of nanostructured hydroxyapatite (nHAp), and its application potentials for controlled drug delivery, drug conjugation, and other biomedical treatments. Aspects associated with efficient utilization of hydroxyapatite (HAp) nanostructures such as their synthesis, interaction with drug molecules, and other concerns, which need to be resolved before they could be used as a potential drug carrier in body system, are discussed. This review focuses on the evolution of perceptions, practices, and accomplishments in providing improved delivery systems for drugs until date. The pioneering developments that have presaged today's fascinating state of the art drug delivery systems based on HAp and HAp-based composite nanostructures are also discussed. Special emphasis has been given to describe the application and effectiveness of modified HAp as drug carrier agent for different diseases such as bone-related disorders, carriers for antibiotics, anti-inflammatory, carcinogenic drugs, medical imaging, and protein delivery agents. As only a very few published works made comprehensive evaluation of HAp nanostructures for drug delivery applications, we try to cover the three major areas: concepts, practices and achievements, and applications, which have been consolidated and patented for their practical usage. The review covers a broad spectrum of nHAp and HAp modified inorganic drug carriers, emphasizing some of their specific aspects those needed to be considered for future drug delivery applications.

AB - BACKGROUND: As a bio-psycho-social issue, chronic low back pain (CLBP) has been a significant topic in health management, and patients' quality of life (QOL) is gaining extensive attention. Self-efficacy, pain fear-avoidance belief (FAB), and coping styles play important roles in the QOL of CLBP patients. However, it remains unclear how self-efficacy and FAB influence QOL through specific coping styles. This study aimed to explore the influencing paths of self-efficacy, FAB, and coping styles on the QOL of patients with CLBP. METHODS: This study relies on a multisite, cross-sectional design involving 221 CLBP patients. Stepwise multiple regression and structural equation modeling were employed. RESULTS: CLBP patients lived with a poor global QOL. Self-efficacy played a direct, positive role in predicting QOL for patients with CLBP (beta = 0.35), and it also played an indirect, positive role in predicting QOL (beta = 0.19) through active coping styles (beta = 0.31). FAB played a direct, negative role in predicting QOL (beta = -0.33), and it also played an indirect, negative role in predicting QOL (beta = -0.32) through passive coping styles (beta = 0.32). CONCLUSIONS: Self-efficacy and FAB are both directly and indirectly related to global QOL, and coping styles are important mediating variables. Self-efficacy and active coping are protective factors for the QOL of CLBP patients, while FAB and passive coping are risk factors. Health education strategies are recommended by medical personnel to enhance CLBP patients' pain self-efficacy, decrease pain FAB, and modify pain coping styles, so that their global QOL can be improved. PMID- 29171175 TI - Computational predictions of damage propagation preceding dissection of ascending thoracic aortic aneurysms. AB - Dissections of ascending thoracic aortic aneurysms (ATAAs) cause significant morbidity and mortality worldwide. They occur when a tear in the intima-media of the aorta permits the penetration of the blood and the subsequent delamination and separation of the wall in 2 layers, forming a false channel. To predict computationally the risk of tear formation, stress analyses should be performed layer-specifically and they should consider internal or residual stresses that exist in the tissue. In the present paper, we propose a novel layer-specific damage model based on the constrained mixture theory, which intrinsically takes into account these internal stresses and can predict appropriately the tear formation. The model is implemented in finite-element commercial software Abaqus coupled with user material subroutine. Its capability is tested by applying it to the simulation of different exemplary situations, going from in vitro bulge inflation experiments on aortic samples to in vivo overpressurizing of patient specific ATAAs. The simulations reveal that damage correctly starts from the intimal layer (luminal side) and propagates across the media as a tear but never hits the adventitia. This scenario is typically the first stage of development of an acute dissection, which is predicted for pressures of about 2.5 times the diastolic pressure by the model after calibrating the parameters against experimental data performed on collected ATAA samples. Further validations on a larger cohort of patients should hopefully confirm the potential of the model in predicting patient-specific damage evolution and possible risk of dissection during aneurysm growth for clinical applications.

AB - This study evaluated patterns of response as discerned by comprehensive metastasis-specific analysis in metastatic melanoma patients receiving anti-PD-1 antibodies. Bi-dimensional measurements of every metastasis in patients enrolled in the KEYNOTE-001 trial at a single institution were obtained at baseline and throughout treatment. Twenty-seven evaluable patients had 399 baseline metastases measurable on CT imaging. Complete response (CR) which occurred in 52.6% of metastases was smaller (mean 223 mm2 versus 760 mm2 , p < .01) and occurred more frequently in the lungs (65% versus 39.4%, p < .01). Response was heterogenous (new/progressing metastases alongside CR metastases) at first assessment in 4/14 patients with objective response (OR) as opposed to 7/13 patients with non-OR. CR of individual metastases is common and influenced by site and size. Most patients with OR demonstrate homogenous regression in all metastases at the first assessment. In contrast, patients with early heterogeneity had a poor outcome. PMID- 29171177 TI - Extracellular matrix remodeling in 3D: implications in tissue homeostasis and disease progression. AB - The extracellular matrix (ECM) plays a critical role in regulating cell behavior during tissue homeostasis and in disease progression. Through a combination of adhesion, contraction, alignment of ECM proteins and subsequent degradation, cells change the chemical, mechanical, and physical properties of their surrounding matrix. Other contributing factors to matrix remodeling are the de novo synthesis of ECM proteins, post-translational modifications and receptor mediated internalization. In this review, we highlight how each of these processes contributes to the maintenance of homeostasis and in disease conditions such as cancer and liver fibrosis.

PMID- 29171178 TI - HIV viral load monitoring among key populations in low- and middle-income countries: challenges and opportunities. AB - INTRODUCTION: Key populations bear a disproportionate HIV burden and have substantial unmet treatment needs. Routine viral load monitoring represents the gold standard for assessing treatment response at the individual and programme levels; at the population-level, community viral load is a metric of HIV programme effectiveness and can identify "hotspots" of HIV transmission. Nevertheless, there are specific implementation and ethical challenges to effectively operationalize and meaningfully interpret viral load data at the community level among these often marginalized populations. DISCUSSION: Viral load monitoring enhances HIV treatment, and programme evaluation, and offers a better understanding of HIV surveillance and epidemic trends. Programmatically, viral load monitoring can provide data related to HIV service delivery coverage and quality, as well as inequities in treatment access and uptake. From a population perspective, community viral load data provides information on HIV transmission risk. Furthermore, viral load data can be used as an advocacy tool to demonstrate differences in service delivery and to promote allocation of resources to disproportionately affected key populations and communities with suboptimal health outcomes. However, in order to perform viral load monitoring for individual and programme benefit, health surveillance and advocacy purposes, careful consideration must be given to how such key population programmes are designed and implemented. For example, HIV risk factors, such as particular sex practices, sex work and drug use, are stigmatized or even criminalized in many contexts. Consequently, efforts must be taken so that routine viral load monitoring among marginalized populations does not cause inadvertent harm. Furthermore, given the challenges of reaching representative samples of key populations, significant attention to meaningful recruitment, decentralization of care and interpretation of results is needed. Finally, improving the interoperability of health systems through judicious use of biometrics or identifiers when confidentiality can be maintained is important to generate more valuable data to inform monitoring programmes. CONCLUSIONS: Opportunities for expanded viral load monitoring could and should benefit all those affected by HIV, including key populations. The promise of the increasing routinization of viral load monitoring as a tool to advance HIV treatment equity is great and should be prioritized and appropriately implemented within key population programmatic and research agendas. PMID- 29171179 TI - Optimal timing of viral load monitoring during pregnancy to predict viraemia at delivery in HIV-infected women initiating ART in South Africa: a simulation study. AB - INTRODUCTION: HIV viral load (VL) monitoring is a central tool to evaluate ART effectiveness and transmission risk. There is a global movement to expand VL monitoring following recent recommendations from the World Health Organization (WHO), but there has been little research into VL monitoring in pregnant women. We investigated one important question in this area: when and how frequently VL should be monitored in women initiating ART during pregnancy to predict VL at the time of delivery in a simulated South African population. METHODS: We developed a mathematical model simulating VL from conception through delivery using VL data from the Maternal and Child Health - Antiretroviral Therapy (MCH-ART) cohort. VL was modelled based on three major compartments: pre-ART VL, viral decay immediately after ART initiation and viral maintenance (including viral suppression and viraemic episodes). Using this simulation, we examined the performance of various VL monitoring schema in predicting elevated VL at delivery. RESULTS AND DISCUSSION: If WHO guidelines for non-pregnant adults were used, the majority of HIV-infected pregnant women (69%) would not receive a VL test during pregnancy. Most models that based VL monitoring in pregnancy on the time elapsed since ART initiation (regardless of gestation) performed poorly (sensitivity <50%); models that based VL measures in pregnancy on the woman's gestation (regardless of time on ART) appeared to perform better overall (sensitivity >60%). Across all permutations, inclusion of pre-ART VL values had a negligible impact on predictive performance (improving test sensitivity and specificity <6%). Performance of VL monitoring in predicting VL at delivery generally improved at later gestations, with the best performing option a single VL measure at 36 weeks' gestation. CONCLUSIONS: Development and evaluation of a novel simulation model suggests that strategies to measure VL relative to gestational age may be more useful than strategies relative to duration on ART, in women initiating ART during pregnancy, supporting better integration of maternal and HIV health services. Testing turnaround times require careful consideration, and point-of-care VL testing may be the best approach for measuring VL at delivery. Broadening the scope of this simulation model in the light of current scale up of VL monitoring in high burden countries is important.

AB - Vertebrate eye development and homoeostasis critically depend on the regulation of proliferation of cells forming the retinal pigment epithelium (RPE). Previous results indicated that the death-associated protein like-1 DAPL1 cell autonomously suppresses RPE proliferation in vivo and in vitro. Here, we show in human RPE cell lines that the pigment cell transcription factor MITF regulates RPE cell proliferation by upregulating DAPL1 expression. DAPL1 regulation by MITF is, however, mediated predominantly by (-) MITF, one of two alternative splice isoforms of MITF that lacks six residues located upstream of the DNA-binding basic domain. Furthermore, we find that the regulation of DAPL1 by MITF is indirect in that (-) MITF stimulates the transcription of Musashi homolog-2 (MSI2), which negatively regulates the processing of the anti-DAPL1 microRNA miR 7. Our results provide molecular insights into the regulation of RPE cell proliferation and quiescence and may help us understand the mechanisms of normal RPE maintenance and of eye diseases associated with either RPE hyperproliferation or the lack of regenerative proliferation. PMID- 29171180 TI - The case for viral load testing in adolescents in resource-limited settings. AB - INTRODUCTION: The success of HIV treatment programmes globally has resulted in children with perinatally acquired HIV reaching adolescence in large numbers. The number of adolescents living with HIV is growing further due to persisting high HIV incidence rates among adolescents in low- and middle-income settings, particularly in sub-Saharan Africa. Although expanding access to HIV viral load monitoring is necessary to achieve the 90-90-90 targets across the HIV care continuum, implementation is incomplete. We discuss the rationale for prioritizing viral load monitoring among adolescents and the associated challenges. DISCUSSION: Adolescents with HIV are a complex group to treat successfully due to extensive exposure to antiretroviral therapy for those with perinatally acquired HIV and the challenges in sustained medication adherence in this age group. Given the high risk of treatment failure among adolescents and the limited drug regimens available in limited resource settings, HIV viral load monitoring in adolescents could prevent unnecessary and costly switches to second line therapy in virologically suppressed adolescents. Because adolescents living with HIV may be heavily treatment experienced, have suboptimal treatment adherence, or may be on second or even third-line therapy, viral load testing would allow clinicians to make informed decisions about increased counselling and support for adolescents together with the need to maintain or switch therapeutic regimens. CONCLUSIONS: Given scarce resources, prioritization of viral load testing among groups with a high risk of virological failure may be required. Adolescents have disproportionately high rates of virological failure, and targeting this age group for viral load monitoring may provide valuable lessons to inform broader scale-up. PMID- 29171182 TI - Acid hydrolysis reveals a low but constant level of pheomelanin in human black to brown hair. AB - We previously reported a constant ratio of the benzothiazole pheomelanin marker thiazole-2,4,5-tricarboxylic acid (TTCA) to the eumelanin marker pyrrole-2,3,5 tricarboxylic acid (PTCA) in eumelanic, black human hair. A constant level (20% 25%) of benzothiazole-type pheomelanin was recently demonstrated in human skin with varying concentrations of melanin. Therefore, in this study, we aimed to investigate the origin of pheomelanin markers in black to brown human hair by developing a method to remove protein components from hair by heating with 6 M HCl at 110 degrees C for 16 hr. For comparison, synthetic melanins were prepared by oxidizing mixtures of varying ratios of dopa and cysteine with tyrosinase. Hair melanins and synthetic melanins were subjected to acid hydrolysis followed by alkaline H2 O2 oxidation. The results show that the hydrolysis leads to decarboxylation of the 5,6-di-hydroxyindole-2-carboxylic acid moiety in eumelanin and the benzothiazole moiety in pheomelanin and that eumelanic human hair contains 11%-17% benzothiazole-type pheomelanin. PMID- 29171183 TI - Cause-specific mortality in HPV+ and HPV- oropharyngeal cancer patients: insights from a population-based cohort. AB - Identifying the causes of death in head and neck cancer patients can optimize follow-up and therapeutic strategies, but studies in oropharyngeal squamous cell carcinoma (OPSCC) patients stratified by HPV status are lacking. We report cause specific mortality in a population-based cohort of patients with OPSCC. Patients who had been diagnosed with OPSCC (n = 1541) between 2000 and 2014 in eastern Denmark were included in the study. Causes of death were collected through medical files and the Danish National Cause of Death registry. Deaths were grouped as (1) primary oropharyngeal cancer, (2) secondary malignancies, (3) cardiovascular and pulmonary disease, or (4) other/unspecified. The cumulative incidence of death and specific causes of death were determined using risk analysis. At follow-up, 723 (47.5%) patients had died. The median time to and cause of death were determined: oropharyngeal cancer (n = 432; 1.00 year), secondary malignancies (n = 131; 2.37 years), cardiovascular and pulmonary causes (n = 58; 3.48 years), and unspecified causes (n = 102; 3.42 years). HPV/p16 status was the strongest predictor of improved survival across all causes of death. The only cause of death to decrease in incidence over the 2 years after treatment was death from OPSCC. HPV/p16 positivity was an independent factor for improved survival across all causes of death in patients with OPSCC. In addition, both HPV-positive and HPV-negative OPSCC patients faced high 5- and 10-year mortality rates. Implementing secondary screening and prevention strategies for late toxicity and mortality are major goals in managing the treatment of these patients.

AB - PHACE syndrome is the association of segmental facial hemangiomas with congenital arterial, brain, cardiac, and ocular anomalies. Structural brain malformations affect 41-52% of PHACE patients and can be associated with focal neurologic deficits, developmental delays, and/or intellectual disability. To better characterize the spectrum of structural brain and other intracranial anomalies in PHACE syndrome, MRI scans of the head/neck were retrospectively reviewed in 55 patients from the PHACE Syndrome International Clinical Registry and Genetic Repository. All registry patients with a diagnosis of definite PHACE syndrome who had MRI scans of satisfactory quality were included. Of 55 patients, 34 (62%) demonstrated >=1 non-vascular intracranial anomaly; structural brain malformations were present in 19 (35%). There was no difference in the prevalence of brain anomalies between genders. Brain anomalies were more likely in patients with S1 and/or S2 distribution of facial hemangioma. The most common structural brain defects were cerebellar hypoplasia (25%) and fourth ventricle abnormalities (13%). Dandy-Walker complex and malformations of cortical development were present in 9% and 7%, respectively. Extra-axial findings such as pituitary anomalies (18%) and intracranial hemangiomas (18%) were also observed. Six patients (11%) had anomalies of the globes or optic nerve/chiasm detectable on MRI. Brain malformations comprise a diverse group of structural developmental anomalies that are common in patients with PHACE syndrome. Along with brain malformations, numerous abnormalities of the pituitary, meninges, and globes were observed, highlighting the need for careful radiologic assessment of these structures in the neuroimaging workup for PHACE syndrome. PMID- 29171185 TI - Low-grade inflammation and muscular fitness on insulin resistance in adolescents: Results from LabMed Physical Activity Study. AB - BACKGROUND: Low muscular fitness (MF) and low-grade inflammation has been linked to insulin resistance (IR). OBJECTIVE: To evaluate the associations between MF and a clustered score of inflammatory biomarkers on IR and to investigate the combined impact of MF and inflammation on IR in adolescents. METHODS: This is a cross-sectional analysis with 529 adolescents (267 girls) aged 12 to 18 years. Pubertal stage, socioeconomic status, adherence to the Mediterranean diet, cardiorespiratory fitness, and waist circumference were assessed. Standing long jump and isometric handgrip dynamometry were used as indicators of MF. Continuous score of clustered inflammatory biomarkers (InflaScore) (sum of Z-scores of C reactive protein, C3, C4, fibrinogen, and leptin) and IR (homeostasis model assessment of insulin resistance [HOMA-IR] estimated from fasting serum insulin and glucose) were assessed. RESULTS: HOMA-IR and fasting insulin were positively associated with InflaScore and negatively associated with MF, independently of age, sex, pubertal stage, socioeconomic status, adherence to the Mediterranean diet, cardiorespiratory fitness, and waist circumference. Adolescents classified as High InflaScore/Unfit showed significantly higher HOMA-IR when compared than those with High InflaScore/Fit and those with Low InflaScore/Fit (F(3,519) = 4.761, P < .003), after adjustments for potential confounders. Unfit adolescents with high InflaScore had the highest odds of expressing high HOMA-IR (odds ratio, OR = 2.40, 95% confidence interval [CI]: 1.2-5.6) and insulin risk (2.53 95% CI, 1.5-5.9) when compared to those of the Low InflaScore/Fit group, after adjustments for potential confounders. CONCLUSION: Higher levels of MF seem to minimize the deleterious effect of inflammation on IR.

PMID- 29171187 TI - The effect of allogeneic cardiac stem cells in left ventricular geometry and function in a rat model of myocardial infarction. AB - BACKGROUND: The development of heart failure after acute myocardial infarction (MI) was related to left ventricular (LV) pathological remodeling and dysfunction. Cardiac stem cells (CSCs) provided a new option to treat acute MI. This study was to investigate the effects of CSCs on structural and functional alteration in acute MI. METHODS: Acute MI was induced in 20 Sprague-Dawley rats by ligation of the left anterior descending coronary artery. Two weeks after MI, animals were randomized into CSCs or control group. LV geometry and function were echocardiographically measured at baseline, 2, 4, and 6 weeks after MI. After measuring hemodynamics at 6 weeks after MI, hearts were harvested for tracing CSCs stained by PKH26 and testing expression of VEGF-alpha/TGF-beta1 by RT-PCR and ELISA. RESULTS: Two weeks after MI, there were significant decreases in interventricular septal systolic and diastolic thickness (IVSTs/d), while increases in LV systolic and diastolic dimension (LVDs/d). Consequently, this contributed to decreases in ejection fraction (EF) and fractional shorting (FS). With the treatment of CSCs for 4 weeks, significant better ejection fraction (EF) and fractional shorting (FS) were achieved in CSCs group accompanied by the reduction in LV systole and diastole dimension (LVDs/d). Besides, a significant improvement in the maximal rate of LV pressure development and decline (peak +dP/dt and -dP/dt, respectively) was observed. Moreover, significantly higher VEGF-alpha was expressed in CSCs group rather than TGF-beta1. CONCLUSION: CSCs significantly prevented structural and functional deterioration after MI with increasing expression of VEGF-alpha. PMID- 29171189 TI - Synthetic lethality in DNA repair network: A novel avenue in targeted cancer therapy and combination therapeutics. AB - Synthetic lethality refers to a lethal phenotype that results from the simultaneous disruptions of two genes, while the disruption of either gene alone is viable. Many DNA double strand break repair (DSBR) genes have synthetic lethal relationships with oncogenes and tumor suppressor genes, which can be exploited for targeted cancer therapy, an approach referred to as combination therapy. DNA double-strand breaks (DSBs) are one of the most toxic lesions to a cell and can be repaired by non-homologous end joining (NHEJ) or homologous recombination (HR). HR and NHEJ genes are particularly attractive targets for cancer therapy because these genes have altered expression patterns in cancer cells when compared with normal cells and these genetic abnormalities can be targeted for selectively killing cancer cells. Here, we review recent advances in the development of small molecule inhibitors against HR and NHEJ genes to induce synthetic lethality and address the future directions and clinical relevance of this approach.

AB - INTRODUCTION: The objective of this commentary is to review considerations for implementing routine viral load (VL) monitoring programmes for HIV-infected infants and children living in low- and middle-income countries (LMIC). Since 2013, the World Health Organization (WHO) guidelines recommend VL testing as the preferred monitoring approach for all individuals treated with ART in order to assess treatment response, detect treatment failure and determine the need to switch to a second-line regimen in a timely manner. More recently, WHO guidelines from 2016 identify HIV-infected infants and children as a priority group for routine VL monitoring. DISCUSSION: There are a number of reasons why HIV-infected infants and children should be prioritized for routine VL monitoring. Data from national VL monitoring programmes as well as systematic reviews and meta-analyses from LMIC indicate rates of viral suppression are lower for infants and children compared to adults. The number of antiretroviral drugs and palatable formulations suitable for young children are limited. In addition, emotional and developmental issues particular to children can make daily medication administration difficult and pose a challenge to adherence and achievement of sustained viral suppression. VL monitoring can be instrumental for identifying those in need of additional adherence support, reducing regimen switches and preserving treatment options. The needs of infants and children warrant consideration in all aspects of VL monitoring services. If capacity for paediatric venipuncture is not assured, platforms that accept dried blood spot specimens are necessary in order for infants and children to have equitable access. Healthcare systems also need to prepare to manage the substantial number of infants and children identified with elevated VL, including adherence interventions that are appropriate for children. Establishing robust systems to evaluate processes and outcomes of routine VL monitoring services and to support drug forecasting and supply management is essential to determine best practices for infants and children in LMIC. CONCLUSIONS: The particular concerns of HIV-infected infants and children warrant attention during all phases of planning and implementation of VL monitoring services. There are a number of key areas, including frequency of monitoring, blood specimen type and adherence challenges, where specific approaches tailored for infants and children may be required. PMID- 29171191 TI - Pre-Zika descriptive epidemiology of microcephaly in Texas, 2008-2012. AB - BACKGROUND: There are limited population-based studies on microcephaly. We characterized the epidemiology of microcephaly in Texas during a 5-year period (2008-2012), prior to the Zika epidemic in the Western hemisphere (2015). The associations of suspected risk factors were compared across four clearly defined case groups. METHODS: Data from the Texas Birth Defects Registry were used to calculate the prevalence of congenital microcephaly and crude and adjusted prevalence ratios using Poisson regression. Twelve maternal and infant factors were assessed across case groups, which included total (explained + unexplained), explained (e.g., syndromic), unexplained, and severe unexplained microcephaly (head circumference <3rd percentile). RESULTS: The birth prevalence for total and total severe microcephaly were 14.7 and 4.8 per 10,000 livebirths, respectively. For explained and unexplained cases, significantly elevated risks were noted for mothers who were older (35+), less educated (<=12 years), diabetic (pre-pregnancy or gestational), or had a preterm delivery. Unlike explained cases, however, mothers who were non-White or smoked had an increased risk for unexplained microcephaly. Furthermore, young maternal age (<20), multiparity, and higher BMI reduced the risk for unexplained microcephaly. For severe unexplained cases, the risk profile was similar to that for all unexplained cases-with the exception of null associations noted for diabetes and birth year. CONCLUSIONS: We found that risk patterns for microcephaly varied across case groupings. Risk factors included maternal race/ethnicity, age, and smoking during pregnancy. Among severe unexplained cases, notable positive associations were seen among mothers who were non-Hispanic Black or less educated, while inverse associations were noted for obesity.

AB - BACKGROUND: During the fall of 2014, the threat of an Ebola outbreak gripped the United States (Poll, 8-12 October 2014; see Harvard School of Public Health & SSRS, 2014), creating a unique opportunity to advance basic knowledge concerning how emotion regulation works in consequential contexts and translate existing research in this area to inform public health and policy. METHOD: We addressed these issues by examining whether third-person self-talk, a simple technique that promotes emotion regulation, could nudge people into reasoning about Ebola more rationally. In all, 1,257 people from across the United States were asked to write about their feelings about Ebola using their name or I (i.e. third-person self-talk vs. first-person self-talk) as concerns about Ebola swelled (24 October 2014-26 October 2014). RESULTS: Third-person self-talk led participants who scored high on Ebola worry at baseline to generate more fact-based reasons not to worry about Ebola, which predicted reductions in their Ebola worry and risk perception. These findings held when controlling for several theoretically relevant covariates, highlighting their robustness. CONCLUSION: These results demonstrate how a simple linguistic technique can enhance rational thinking and quell worry about a pressing public health threat. PMID- 29171193 TI - Returning HIV-1 viral load results to participant-selected health facilities in national Population-based HIV Impact Assessment (PHIA) household surveys in three sub-Saharan African Countries, 2015 to 2016. AB - INTRODUCTION: Logistical complexities of returning laboratory test results to participants have precluded most population-based HIV surveys conducted in sub Saharan Africa from doing so. For HIV positive participants, this presents a missed opportunity for engagement into clinical care and improvement in health outcomes. The Population-based HIV Impact Assessment (PHIA) surveys, which measure HIV incidence and the prevalence of viral load (VL) suppression in selected African countries, are returning VL results to health facilities specified by each HIV positive participant within eight weeks of collection. We describe the performance of the specimen and data management systems used to return VL results to PHIA participants in Zimbabwe, Malawi and Zambia. METHODS: Consenting participants underwent home-based counseling and HIV rapid testing as per national testing guidelines; all confirmed HIV positive participants had VL measured at a central laboratory on either the Roche CAP/CTM or Abbott m2000 platform. On a bi-weekly basis, a dedicated data management team produced logs linking the VL test result with the participants' contact information and preferred health facility; project staff sent test results confidentially via project drivers, national courier systems, or electronically through an adapted short message service (SMS). Participants who provided cell phone numbers received SMS or phone call alerts regarding availability of VL results. RESULTS AND DISCUSSION: From 29,634 households across the three countries, 78,090 total participants 0 to 64 years in Zimbabwe and Malawi and 0 to 59 years in Zambia underwent blood draw and HIV testing. Of the 8391 total HIV positive participants identified, 8313 (99%) had VL tests performed and 8245 (99%) of these were returned to the selected health facilities. Of the 5979 VL results returned in Zimbabwe and Zambia, 85% were returned within the eight-week goal with a median turnaround time of 48 days (IQR: 33 to 61). In Malawi, where exact return dates were unavailable all 2266 returnable results reached the health facilities by 11 weeks. CONCLUSIONS: The first three PHIA surveys returned the vast majority of VL results to each HIV positive participant's preferred health facility within the eight-week target. Even in the absence of national VL monitoring systems, a system to return VL results from a population-based survey is feasible, but it requires developing laboratory and data management systems and dedicated staff. These are likely important requirements to strengthen return of results systems in routine clinical care. PMID- 29171195 TI - The Dynamic Nature of Self-Assessed Health (SAH) as a Function of Negative and Positive Affects among Cardiac Patients. AB - BACKGROUND: Self-assessed health (SAH) predicts health outcomes above and beyond medical variables. One of the explanations for this robust finding is the sensitivity of SAH to changes in multiple aspects of health, including emotional factors. We assessed the dynamic nature of SAH by longitudinally examining the associations between initial and change levels of SAH and positive affect (PA) and negative affect (NA). METHODS: Participants were 138 cardiac patients undergoing coronary angioplasty. Self-report questionnaires measured SAH, PA, and NA, one day and one month after catheterisation. RESULTS: Means of SAH and NA did not change between measurement points, but PA decreased. Cross-lagged analysis indicated that the best model for representing the data included a path from affect at hospitalisation to SAH one month later; that is, lower NA (but not PA) at hospitalisation predicted higher SAH a month later. A latent change model analysis also revealed that NA (but not PA) at hospitalisation predicted changes in SAH (but SAH did not predict changes in negative or positive affect); and that increases in positive affect and decreases in negative affect were linked to increases in SAH. CONCLUSIONS: These findings highlight the importance of NA as an indicator of SAH and SAH change, and provide further insights into the dynamics of SAH in cardiac patients. PMID- 29171196 TI - Clinical and Subclinical Distress, Quality of Life, and Psychological Well-Being after Cardiac Rehabilitation. AB - BACKGROUND: The literature has outlined positive effects of cardiac rehabilitation (CR) on clinical psychological distress (DSM depression and anxiety) and quality of life (QoL). In cardiac settings, subclinical distress (subthreshold depressive and anxious symptomatology) and psychological well-being also showed relevant clinical implications. This research explored these psychological variables, their changes over time and cardiac course of CR patients. METHODS: Clinical and subclinical distress, QoL, and psychological well being were assessed in 108 consecutive patients undergoing CR, at baseline and up to 12 months after the program's completion. RESULTS: Of all patients, 25.9 per cent showed high distress with a DSM diagnosis, 31.5 per cent high distress without a DSM diagnosis, and 42.6 per cent low distress. Comparing these subgroups, worse QoL and psychological well-being were significantly linked not only to clinical but also to subclinical distress. After CR completion, a significant reduction in DSM diagnoses was observed, whereas there were no positive effects on subclinical distress, QoL, and well-being, or when they initially occurred, they were not long lasting. Moreover, only the subgroup with high distress without a DSM diagnosis was at greater risk for adverse cardiac outcomes, showing worse scores on items of contentment. CONCLUSIONS: These findings confirm data on clinical distress reduction after CR completion. However, a large amount of relevant subclinical distress remains and predicts adverse cardiac events. PMID- 29171197 TI - Socioeconomic Context as a Moderator in the Relationship between Body Mass Index and Depression in Europe. AB - BACKGROUND: Obesity and depression are two major health issues in contemporary societies. This study aims to address two fundamental questions: (1) what is the impact of macro-level adverse socioeconomic circumstances on depression? and (2) how do macro-level variations in the socioeconomic context affect the relationship between body mass index (BMI) and depression? METHODS: Data from the 7th round of the European Social Survey were used, collected from a sample size of 37,623 participants and aggregated around a total of 20 countries. A random intercept multilevel model was constructed to study the variations in the relationship between depression and BMI. The contextual effect of risk of poverty, unemployment rate, and gross domestic product per capita were studied at the country level. RESULTS: First, both unemployment and poverty risk were found to be positively associated with depressive disorders. Second, the results show that a higher risk of poverty at the macro level may increase the effect of BMI on depression in European countries. CONCLUSION: The present study provides new evidence suggesting that the obesity-depression relationship will be, on average, stronger in countries with poor socioeconomic conditions. Therefore, adverse socioeconomic contextual conditions may increase depression associated with obesity. PMID- 29171198 TI - Ischemia-based Coronary Revascularization: Beyond Anatomy and Fractional Flow Reserve. AB - Treatment strategies for patients with coronary artery disease (CAD) should be based on objective evidence of inducible ischemia in the subtended myocardium to improve clinical outcomes, symptoms, and cost-effectiveness. Fractional flow reserve (FFR) is the most verified index to-date for invasively evaluating lesion specific myocardial ischemia. Favorable results from large clinical trials that applied FFR-guided percutaneous coronary intervention (PCI) prompted changes in coronary revascularization guidelines to emphasize the importance of this ischemia-based strategy using invasive coronary physiology. However, the frequency of functional evaluations is lacking in daily practice, and visual assessment still dominates treatment decisions in CAD patients. Despite recent efforts to integrate functional and anatomical assessments for coronary stenosis, there is considerable discordance between the 2 modalities, and the diagnostic accuracy of simple parameters obtained from current imaging tools is not satisfactory to determine functional significance. Although evidence that supports or justifies anatomy-guided PCI is more limited, and FFR-guided PCI is currently recommended, it is important to be aware of conditions and factors that influence FFR for accurate interpretation and application. In this article, we review the limitations of the current anatomy-derived evaluation of the functional significance of coronary stenosis, detail considerations for the clinical utility of FFR, and discuss the importance of an integrated physiologic approach to determine treatment strategies for CAD patients.

PMID- 29171200 TI - Clinical Characteristics of Korean Patients with Bicuspid Aortic Valve Who Underwent Aortic Valve Surgery. AB - BACKGROUND AND OBJECTIVES: Clinical data for Korean patients with bicuspid aortic valve (BAV) that underwent aortic valve (AV) surgery are currently limited. METHODS: Data for 1,160 consecutive adult BAV patients who underwent AV surgery from 2000 to 2014 in 4 tertiary referral centers were retrospectively analyzed. A standard case report form was used for clinical and echocardiographic parameters. RESULTS: Mean age at the time of AV surgery was 59+/-13 years. The most common cause of AV surgery was aortic stenosis (AS, 892 [77%]), followed by aortic regurgitation (AR, 199 [17%]), and infective endocarditis (69 [6%]). AS showed a skewed peak in the aged population and was the predominant cause of AV surgery (87%) in patients >=50 years of age, whereas AR (46%) and active infective endocarditis (19%) were more common in younger patients (p<0.001). Echocardiographic determination of the BAV phenotype revealed that fusion of the right coronary cusp (RCC) and left coronary cusp (LCC) was most common (622 [53%]), followed by fusion of RCC and non-coronary cusp (NCC) (313 [27%]), and fusion of LCC and NCC (42 [4%]); the BAV phenotype could not be determined in the remaining 183 patients (16%). Fusion of RCC and LCC was more commonly observed in patients with AR than in those with AS (74% vs. 49%; p<0.001). CONCLUSION: BAV patients were characterized by distinct surgical indications according to their age. Possible associations between BAV phenotypes and surgical indications with potential impacts of ethnicity need to be tested in further studies. PMID- 29171201 TI - Carotid Artery Stenting. AB - Carotid artery stenosis is relatively common and is a significant cause of ischemic stroke, but carotid revascularization can reduce the risk of ischemic stroke in patients with significant symptomatic stenosis. Carotid endarterectomy has been and remains the gold standard treatment to reduce the risk of carotid artery stenosis. Carotid artery stenting (CAS) (or carotid artery stent implantation) is another method of carotid revascularization, which has developed rapidly over the last 30 years. To date, the frequency of use of CAS is increasing, and clinical outcomes are improving with technical advancements. However, the value of CAS remains unclear in patients with significant carotid artery stenosis. This review article discusses the basic concepts and procedural techniques involved in CAS. PMID- 29171202 TI - Advances in Intravascular Imaging: New Insights into the Vulnerable Plaque from Imaging Studies. AB - The term "vulnerable plaque" denotes the plaque characteristics that are susceptible to coronary thrombosis. Previous post-mortem studies proposed 3 major mechanisms of coronary thrombosis: plaque rupture, plaque erosion, and calcified nodules. Of those, characteristics of rupture-prone plaque have been extensively studied. Pathology studies have identified the features of rupture-prone plaque including thin fibrous cap, large necrotic core, expansive vessel remodeling, inflammation, and neovascularization. Intravascular imaging modalities have emerged as adjunctive tools of angiography to identify vulnerable plaques. Multiple devices have been introduced to catheterization laboratories to date, including intravascular ultrasound (IVUS), virtual-histology IVUS, optical coherence tomography (OCT), coronary angioscopy, and near-infrared spectroscopy. With the use of these modalities, our understanding of vulnerable plaque has rapidly grown over the past several decades. One of the goals of intravascular imaging is to better predict and prevent future coronary events, for which prospective observational data is still lacking. OCT delineates microstructures of plaques, whereas IVUS visualizes macroscopic vascular structures. Specifically, plaque erosion, which has been underestimated in clinical practice, is gaining an interest due to the potential of OCT to make an in vivo diagnosis. Another potential future avenue for intravascular imaging is its use to guide treatment. Feasibility of tailored therapy for acute coronary syndromes (ACS) guided by OCT is under investigation. If it is proven to be effective, it may potentially lead to major shift in the management of millions of patients with ACS every year.

PMID- 29171203 TI - Association of Syntax Score II with Contrast-induced Nephropathy and Hemodialysis Requirement in Patients with ST Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention. AB - BACKGROUND AND OBJECTIVES: Contrast-induced nephropathy (CIN) is a common complication of primary percutaneous coronary intervention (pPCI) and is associated with high mortality and morbidity and long hospital stay in patients with ST elevation myocardial infarction (STEMI). The Syntax Score (SS) has previously been studied in STEMI patients, and it was associated with increased CIN development and long-term mortality. This study investigates a possible relationship between CIN development and Syntax Score II (SSII) and compares SS and SSII by assessing CIN risk in STEMI patients treated with pPCI. METHODS: A total of 1,234 patients who underwent pPCI were divided into 2 groups according to CIN development. Patients with CIN were further divided into 2 groups according to whether or not they required hemodialysis. Reclassification tables, net reclassification improvement, and integrated discriminative improvement methods were used to assess the additive predictive value of SSII for predicting CIN. RESULTS: In the present study, 166 patients (13.5%) had CIN. Although both SS and SSII were significantly higher in CIN patients, only SSII was an independent predictor of CIN (odds ratio [OR], 1.031; 95% confidence interval [CI], 1.012-1.051; p<0.001) and hemodialysis requirement (OR, 1.078; 95% CI, 1.046-1.078; p<0.001). When comparing SSII and SS in their ability to determine CIN risk, we found SSII to have a reclassification improvement of 27.59% (p<0.001) and an integrated discrimination improvement of 9.1% (p<0.001). CONCLUSIONS: The combination of clinical and anatomic variables can more accurately identify patients who are at high risk for CIN after pPCI. While SSII is harder to calculate than SS, it provides better prediction for CIN and hemodialysis requirement than SS. PMID- 29171205 TI - Factors Predicting Resistance to Intravenous Immunoglobulin Treatment and Coronary Artery Lesion in Patients with Kawasaki Disease: Analysis of the Korean Nationwide Multicenter Survey from 2012 to 2014. AB - BACKGROUND AND OBJECTIVES: Approximately 10-15% of children with Kawasaki disease (KD) do not respond to initial intravenous immunoglobulin (IVIG) and have higher risk for coronary artery lesion (CAL). The aim of this study was to identify predictive factors from laboratory findings in patients who do not respond to IVIG treatment and develop CAL from KD. METHODS: We retrospectively collected nationwide multicenter data from the Korean Society of Kawasaki Disease and included 5,151 patients with KD between 2012 and 2014 from 38 hospitals. RESULTS: Among 5,151 patients with KD, 524 patients belonged to the IVIG-resistant group. The patients in the IVIG-resistant group had a significantly higher serum N terminal pro-brain natriuretic peptide (NT-proBNP) level (1,573.91+/-3,166.46 vs. 940.62+/-2,326.10 pg/mL; p<0.001) and a higher percentage of polymorphonuclear neutrophils (PMNs) (70.89+/-15.75% vs. 62.38+/-32.94%; p<0.001). Multivariate logistic regression analyses revealed that significantly increased PMN, NT proBNP, C-reactive protein (CRP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were the predictors of IVIG resistance (p<0.05). Multivariate logistic regression analyses also showed that only CRP was associated with the risk of CAL (p<0.01), while PMN, NT-proBNP, AST, and ALT were not. CONCLUSIONS: Elevated PMN, serum NT-proBNP, CRP, AST, and ALT levels are significantly associated with IVIG resistance in patients with KD. Moreover, serum CRP is significantly increased in patients with KD with CAL.

PMID- 29171207 TI - Formation and Transformation of Neointima after Drug-eluting Stent Implantation: Insights from Optical Coherence Tomographic Studies. AB - After coronary stent implantation, neointima formation resembles the wound healing process as it involves the sequential processes of inflammation, granulation, and remodeling. Because antiproliferative drugs and polymers of drug eluting stents (DESs) delay vascular healing compared with bare metal stents, fibrin deposition can remain long after stent implantation, or inflammation can be excessive. Delayed vascular healing can be associated with adverse clinical outcomes including DES thrombosis or restenosis, and poor endothelization of DES neointima can accelerate neoatherosclerotic change inside the neointima, further contributing to luminal restenosis or neointimal instability. Despite the lack of correlation between pathologic and optical coherence tomography (OCT) findings, OCT assessments of neointima under various circumstances can reveal vascular responses to stent therapy. Homogeneous, heterogeneous, and layered neointima patterns can be recognized by OCT and can change with time. Homogeneous neointima might be associated with better clinical outcomes after DES implantation, whereas non-homogeneous neointima or neoatherosclerotic change can be associated with poorer clinical outcomes. However, limited data are currently available, and further studies are required to comprehensively address these questions. PMID- 29171208 TI - Real-world Data and Recommended Dosage of Non-vitamin K Oral Anticoagulants for Korean Patients. AB - Regulatory approvals of non-vitamin K antagonist oral anticoagulants (NOACs) have been based on large randomized phase III trials evaluating dabigatran, rivaroxaban, apixaban, or edoxaban relative to warfarin for atrial fibrillation (AF). The results of the trials showed that all NOACs were at least non-inferior to warfarin in the prevention of stroke/thromboembolism and showed lower rates of intracranial bleeding than those associated with warfarin. However, the trials were designed differently, varied in the inclusion/exclusion criteria, and used either one dose or a low/high dose of the NOAC drug. Some of these differences have challenged the ability to directly compare various NOACs, and comparative data on effectiveness and intracranial bleeding are sparse in "real-world" patients. Real-world data complement data from large randomized phase III trials by providing new aspects of the "real-world" absolute risks of ischemic and hemorrhagic stroke associated with NOACs vs. warfarin. Moreover, "real-world" fragile patients might have been included (e.g., patients with increased risk of bleeding, liver disease, and chronic kidney disease), although these patients would be less represented in trials. This paper introduces recently published real-world data of NOACs and further suggests the recommended dosage of NOACs for Korean patients. PMID- 29171209 TI - Relationship between Pulmonary Artery Stiffness and Functional Capacity in Patients with Heart Failure with Reduced Ejection Fraction. AB - BACKGROUND AND OBJECTIVES: Functional capacity varies significantly among patients with heart failure with reduced ejection fraction (HFrEF), and it remains unclear why functional capacity is severely compromised in some patients with HFrEF while it is preserved in others. In this study, we aimed to evaluate the role of pulmonary artery stiffness (PAS) in the functional status of patients with HFrEF. METHODS: A total of 46 heart failure (HF) patients without overt pulmonary hypertension or right HF and 52 controls were enrolled in the study. PAS was assessed on parasternal short-axis view using pulsed-wave Doppler recording of pulmonary flow one centimeter distal to the pulmonic valve annulus at a speed of 100 mm/sec. PAS was calculated according to the following formula: the ratio of maximum flow velocity shift of pulmonary flow to pulmonary acceleration time. RESULTS: PAS was significantly increased in the HFrEF group compared to the control group (10.53+/-2.40 vs. 7.41+/-1.32, p<0.001). In sub group analysis of patients with HFrEF, PAS was significantly associated with the functional class of the patients. HFrEF patients with poor New York Heart Association (NYHA) functional capacity had higher PAS compared those with good functional capacity. In multivariate regression analysis, NYHA class was independently correlated with PAS. CONCLUSION: PAS is associated with functional status and should be taken into consideration as an underlying pathophysiological mechanism of dyspnea in patients with HFrEF. PMID- 29171210 TI - Pericardial-esophageal Fistula Complicating Atrial Fibrillation Ablation Successfully Resolved after Pericardial Drainage with Conservative Management. AB - A 40-year-old male patient underwent radiofrequency catheter ablation for symptomatic paroxysmal atrial fibrillation (AF). Although pulmonary vein (PV) isolation was successfully completed without acute complications, the patient began complaining of sustained retrosternal pain. Seventeen days after ablation, the patient visited the emergency room with fever and severe chest pain with pericarditis-like features. Chest computed tomography (CT) revealed clustered air bubbles in the pericardial space. Esophagography confirmed leakage of contrast agent into the pericardial space but not into the left atrium. While performing pericardiostomy, the operator confirmed the absence of active bleeding from the left atrium. Because there were no signs of left atrial-esophageal fistula, such as systemic embolization, conservative management based on strict fasting with fluids and antibiotic therapy was undertaken. Follow-up esophagography performed 2 weeks later showed no more contrast agent leakage, and the patient was discharged without further incident. PMID- 29171211 TI - A Prospective Survey of Atrial Fibrillation Management for Real-world Guideline Adherence: COmparison study of Drugs for symptom control and complication prEvention of Atrial Fibrillation (CODE-AF) Registry. AB - BACKGROUND AND OBJECTIVES: The aging population is rapidly increasing, and atrial fibrillation (AF) is becoming a significant public health burden in Asia, including Korea. This study evaluated current treatment patterns and guideline adherence of AF treatment. METHODS: In a prospective observational registry (COmparison study of Drugs for symptom control and complication prEvention of Atrial Fibrillation [CODE-AF] registry), 6,275 patients with nonvalvular AF were consecutively enrolled between June 2016 and April 2017 from 10 tertiary hospitals in Korea. RESULTS: The AF type was paroxysmal, persistent, and permanent in 65.3%, 30.0%, and 2.9% of patients, respectively. Underlying structural heart disease was present in 11.9%. Mean CHA2DS2-VASc was 2.7+/-1.7. Oral anticoagulation (OAC), rate control, and rhythm control were used in 70.1%, 53.9%, and 54.4% of patients, respectively. OAC was performed in 82.7% of patients with a high stroke risk. However, antithrombotic therapy was inadequately used in 53.4% of patients with a low stroke risk. For rate control in 192 patients with low ejection fraction (<40%), beta-blocker (65.6%), digoxin (5.2%), or both (19.3%) were adequately used in 90.1% of patients; however, a calcium channel blocker was inadequately used in 9.9%. A rhythm control strategy was chosen in 54.4% of patients. The prescribing rate of class Ic antiarrythmics, dronedarone, and sotalol was 16.9% of patients with low ejection fraction. CONCLUSION: This study shows how successfully guidelines can be applied in the real world. The nonadherence rate was 17.2%, 9.9%, and 22.4% for stroke prevention, rate control, and rhythm control, respectively. PMID- 29171212 TI - Plaque Characteristics and Ruptured Plaque Location according to Lesion Geometry in Culprit Lesions of ST-Segment Elevation Myocardial Infarction. AB - BACKGROUND AND OBJECTIVES: The correlations between plaque characteristics and plaque rupture location according to segmental lesion analysis have not been well defined. The aim of this study was to assess those characteristics of ST-segment elevation myocardial infarction (STEMI) culprit lesions according to segmental lesion geometry using virtual histology intravascular ultrasound (VH-IVUS). METHODS: Sixty single discrete lesions found in the left anterior descending (LAD) coronary arteries of 60 patients with STEMI were included. Each lesion was divided into 3 segments based on lumen area (LA) index, calculated by dividing the lesion LA by the reference LA. RESULTS: Among the 3 segments, the mid-segment showed the highest proportion of necrotic core (NC; proximal, mid-, and distal segments: 20.9+/-11.8%, 22.7+/-11.3%, and 17.5+/-11.2%, respectively, p=0.044). VH-IVUS-derived thin-cap fibroatheroma (VH-TCFA) was also more frequently found in the mid-segment than in proximal and distal segments (36.7%, 58.3%, and 16.7%, p<0.001). The mid-segment also showed the highest prevalence of plaque rupture (45.0%, 78.3% and 11.7%, p<0.001) and thrombus (61.7%, 95.0%, and 41.7%, p<0.001) compared to proximal or distal segments. When the lesions were divided into 2 groups according to the median value (4.0 mm2) of minimum lumen area (MLA), plaque rupture at the distal segment was observed only in high MLA lesions (23.3% vs. 0.0%, p=0.011). CONCLUSION: Analysis of longitudinal lesion geometry using the LA index can be useful in evaluating plaque vulnerability and the incidence of plaque rupture and thrombus in STEMI patients. PMID- 29171213 TI - Extracorporeal Cardiopulmonary Resuscitation with Therapeutic Hypothermia for Prolonged Refractory In-hospital Cardiac Arrest. AB - BACKGROUND AND OBJECTIVES: We identified the impact of extracorporeal cardiopulmonary resuscitation (ECPR) followed by therapeutic hypothermia on survival and neurologic outcome in patients with prolonged refractory in-hospital cardiac arrest (IHCA). METHODS: We enrolled 16 adult patients who underwent ECPR followed by therapeutic hypothermia between July 2011 and December 2015, for IHCA. Survival at discharge and cerebral performance category (CPC) scale were evaluated. RESULTS: All patients received bystander cardiopulmonary resuscitation (CPR); the mean CPR time was 66.5+/-29.9 minutes, and the minimum value was 39 minutes. Eight patients (50%) were discharged alive with favorable neurologic outcomes (CPC 1-2). The mean follow-up duration was 20.1+/-24.3 months, and most deaths occurred within 21 days after ECPR; thereafter, no deaths occurred within one year after the procedure. CONCLUSION: ECPR followed by therapeutic hypothermia could be considered in prolonged refractory IHCA if bystander initiated conventional CPR is performed. PMID- 29171215 TI - Gaps between Real-world Practice and Guidelines in Managing Patients with Atrial Fibrillation in Korea. PMID- 29171216 TI - Nd:YAG laser combined with gold nanorods for potential application in port-wine stains: an in vivo study. AB - Neodymium:yttrium aluminum garnet (Nd:YAG) lasers exhibit considerable potential for treating deeply buried port-wine stains. However, the application of Nd:YAG laser is limited by its weak absorption to blood. This in vivo study tested the efficacy and safety of utilizing thiol-terminated methoxypolyethylene glycol modified gold nanorods (PEG-GNRs) to enhance the absorption of Nd:YAG laser to blood. Mouse mesentery and dorsal skinfold chamber (DSC) model were prepared to analyze the thermal responses of a single venule without anatomic structures, as well as blood vessels in the complex structure of the skin, to laser light. After the injection of 0.44 mg of PEG-GNRs, the required threshold density of laser energy for blood coagulation and complete vasoconstriction decreased from 24 to 18 J/cm2 in the mesentery model and from 36 to 31 J/cm2 in the DSC model. The laser pulse required for blood coagulation and complete vasoconstriction decreased by 67.75% and 62.25% on average in the mesentery model and by 67.55% and 54.45% on average in the DSC model. Histological and histochemical results confirmed that PEG-GNRs are nontoxic in the entire mouse life span. Therefore, combining PEG-GNRs with Nd:YAG laser may be effective and safe for inducing an obvious thermal response of blood vessels under low energy density and minimal pulse conditions. PMID- 29171214 TI - Bioresorbable Vascular Scaffold Korean Expert Panel Report. AB - Bioresorbable vascular scaffold (BRS) is an innovative device that provides structural support and drug release to prevent early recoil or restenosis, and then degrades into nontoxic compounds to avoid late complications related with metallic drug-eluting stents (DESs). BRS has several putative advantages. However, recent randomized trials and registry studies raised clinical concerns about the safety and efficacy of first generation BRS. In addition, the general guidance for the optimal practice with BRS has not been suggested due to limited long-term clinical data in Korea. To address the safety and efficacy of BRS, we reviewed the clinical evidence of BRS implantation, and suggested the appropriate criteria for patient and lesion selection, scaffold implantation technique, and management.

AB - Traditional Chinese medicine (TCM) products are the finished products by adopting certain preparation processes according to the profile of the herbs, with Chinese herbs or decoction pieces as the raw materials.Among their adverse reactions to the organs, hepatotoxicity can not be ignored. As a new stage of quality control in TCM, dynamic quality control system of the multidemensional structure process emphasized on the research of the effectiveness and safety, focused on the pretreatment, preparation process,dosage forms and drug delivery methods to control the quality of TCM preparation products and reduce the generation of hepatotoxicity.In this paper, we will start from these factors to discuss the causes of hepatotoxicity underlying drug products and hope to provide the reference for developing low toxicity and high quality modern Chinese medicine products.

AB - Idiosyncratic drug-induced liver injury (IDILI) is a kind of unique adverse drug reaction with relative high morbidity compared with other idiosyncratic diseases. Its occurrence, however, has nothing to do with pharmacological effects and clinical dosage of drugs administered, and only a small number of susceptible individuals will suffer from it. Especially to deserve to be mentioned, the proportion of TCM-induced IDILI showed an ascending trend year by year. So in this article, the author has reviewed some facts related with TCM-induced IDILI, including the predisposing causes and occurrence mechanism, and tries to provide reference for the prevention, diagnosis and treatment of TCM-induced IDILI through the analysis of characteristics and research status of TCM-induced IDILI and exploration of the internal relationship between Chinese medicine constitution type and IDILI.

AB - Traditional Chinese medicine(TCM) preparation is one of the most important aspects in the development and quality control of traditional Chinese medicine, and its security problem becomes more and more serious. It is worthy to note that the liver, as the main drug metabolic organ, bears the brunt of the damage caused by TCM preparations. In this paper, the author attempts to explore the relationship between TCM preparations and hepatotoxicity based on the processing chains from crude drugs to the end product. Besides, the author hopes to clarify the underlying mechanism of hepatotoxicity of TCM preparations and provide basis and guidance for the quality control and rational clinical use of the preparations as well as the development of modern TCM preparations with high quality and low toxicity.

Rapid detection techniques used for rapid screening of pesticide residues have expanded in a fast progress. As one of the fast development methods of rapid detection, visualization test strip based on nanoparticle has received much concern in recent years. This article focused on the classification of detection test strips and key factors on the fabrication of nanoparticle-based visualization test strips used in small molecule pesticides. Moreover, a wide application of nanoparticles-tagged test strips on pesticide residue was reviewed including single residue detection, multi residue detection, as well as quantitative analysis. Finally, the future application of visual test strip for detecting of pesticide residues in traditional Chinese medicine was forecasted, intending to provide the reference for rapid detection techniques on pesticide residues screening in herbal medicine industry. PMID- 29171222 TI - [Molecular regulative mechanisms of aging and interventional effects of Chinese herbal medicine]. AB - Aging is a gradual process during the loss of functions in cells,organs and tissues by time. The molecular mechanisms of aging-related theories include the classical ones such as telomere,oxygen radical and nonenzymatic glycosylation,as well as the newly proposed ones such as DNA methylation,mitochondrial DNA (mtDNA)and autophagy. The latest study showed the anti-aging effect of autophagy in hematopoietic stem cells. In recent years,based on the molecular regulative mechanisms of aging,a number of the promising anti-aging drugs have been found,including nicotinamide mononucleotide(NMN)and FOXO4-DRI,a peptide of anti aging. In addition,there are many new discoveries in the field of plant extracts,in which,the extracts from Chinese herbal medicine(CHM),some single CHMs and the classical prescriptions of CHM,represented by curcumin and resveratrol,have the partial anti-aging effects by regulating the molecular mechanisms of aging both in vivo and in vitro. In brief,developing or exploring anti-aging drugs,especially the natural drugs,is one of the main development directions in the field of anti-aging research in the basis of the molecular regulative mechanisms of aging. PMID- 29171223 TI - [Recent advances on pericytes in microvascular dysfunction and traditional Chinese medicine prevention]. AB - Pericytesis a kind of widespread vascular mural cells embedded within the vascular basement membrane of blood microvessels, constituting the barrier of capillaries and tissue spaces together with endothelial cells. Pericytes communicate with microvascular endothelial cells through cell connections or paracrine signals, playing an important role in important physiological processes such as blood flow, vascular permeability and vascular formation. Pericytes dysfunction may participate in some microvascular dysfunction, and also mediate pathological repair process, therefore pericytes attracted more and more attention. Traditional Chinese medicine suggests that microvascular dysfunction belongs to the collaterals disease; Qi stagnation and blood stasis in collaterals result in function imbalance of internal organs. Traditional Chinese medicine (TCM) has shown effects on pericytes in microvascular dysfunction, for example qi reinforcing blood-circulation activating medicines can reduce the damage of retinal pericytes in diabetic retinopathy. However, there are some limitations of research fields, inaccuracy of research techniques and methods, and lack of mechanism elaboration depth in the study of microvascular lesion pericytes.

AB - The study was aimed to clarify the effect of three cultivation environments on the growth and metabolism of Dendrobium catenatum C13 group. There were three different cultivation conditions including rock epiphytic cultivation, pear epiphytic cultivation and pot cultivation. Morphological characteristics and agronomic characters of D. catenatum were observed and measured. Microstructure, contents of polysaccharide and alcohol-soluble extracts were measured by paraffin section method, phenol-sulfuric acid method and hot-dip method, respectively. The result showed that the cultivation environment significantly affected the growth of D. catenatum, the leaves of D. catenatum that cultivated on the rock and pear were sparse and small, the stems were short and purple and the root system was developed. Compare with potted cultivation, D. catenatum from rock epiphytic cultivation and pear epiphytic cultivation showed the following characteristics in the microstructure: the upper epidermis became thicker, the epidermal hair in the epidermis became denser, stomatal showed smaller and denser, the cell wall of exodermis, endoderm and medulla became thicker, the cell of velamen, exodermis, endoderm and medulla were smaller and arranged more closely, but the cultivation environment did not produce specific tissue structure, mainly changed in the structural parameters of size and quantity. The growth environments also influenced contents of polysaccharides and alcohol-soluble extracts. The dontents of polysaccharides and alcohol-soluble extracts in D. catenatum from rock epiphytic were the highest, reached 37.34% and 11.66%, the second was pear epiphytic, both higher than pot cultivation, alcohol-soluble extracts contents in D. catenatum from rock epiphytic are more complex, which shows that rock epiphytic is conducive to the accumulation of secondary metabolites in D. catenatum.

AB - In this study, 128 individuals form 14 Epimedium pubescens populations and 1 E. stellulatum population were analyzed by ISSR marker. The data were calculated by POPGENE software and clustered by UPGMA method. Optical microscope was used to observe the main types of the non-glandular hairs and their characteristics in each population. It is found that the following conclusions: Non-glandular hairs can be divided into five morphological categories, long straight pubescent, curly pubescent, appressed curly pubescent, pseudo short appressed hairs and long appressed. Eight primers were screening and a total of 94 bands were detected in ISSR, among which 90 were polymorphic bands. Based on the results of ISSR cluster analysis, 15 populations were divided into 3 clades. E. stellulatum populations should be incorporated into the E. pubescens or as avariety under E. pubescens not be independent and as it has no separate phylogenetic branch for a cluster. The genetic relationship among the populations of E. pubescens was closely related with its geographical distribution and non-glandular hair features. But there were also some inconsistency, which provided a good hint for the further study on the interspecific relationship and natural speciation manner of Epimedium species. Population diversity analysis showed Nm=0.354 4, Nei's=0.585 2. It was showed that E. pubescens has high genetic diversity among populations, for which the main reason was probably the high inbreeding rate and the small range of seed dispersal.

AB - This paper investigated the diversity of the silkworm excrement bacterial communities in different ages before and after drying, aiming to clarify the differences of bacterial communities in composition and bacterial abundance and the influences of drying treatment, and provide scientific basis for the efficacy of scientific connotation and utilization of silkworm excrement. High-throughput sequencing technique was used to measure the sequence of 16S rDNA-V4 variable region of bacteria in silkworm excrement. QIIME, Mothur and PICRUSt software programs were employed to sort and calculate the number of sequences and operational taxonomic units (OTUs) for each sample. Thereafter, the abundance, distribution, alpha diversity index of species, beta diversity and bacterial communities diversity among different sample groups and predicted the bacterial gene functions were analyzed. In this study, the numbers of effective sequences for six samples were 259 250; the rarefaction curves showed a sufficient sequencing depth, and the number of OTUs was close to saturation. The bacteria in silkworm excrement belonged to the following five phylums: Proteobacteria (89.3%), Actinobacteria (5.0%), Firmicutes (4.4%), Bacteroidetes (1.1%) and Cyanobacteria (0.2%). The dominant specie was Cyanobacteria of the total bacteria identified, respectively. The abundances and diversities of the silkworm excrement bacterial communities have been reduced after drying treatment, especially the silkworm excrement of the fifth instar. PICRUSt analysis was performed to show that abundance of the functional genes such as membrane transport, carbohydrate metabolism, amino acid metabolism, lipid metabolism, nucleotide metabolism, cellular processes and signaling were relatively high. The result showed that the drying treatment could decreased the species and numbers of pathogenic bacteria in silkworm excrement obviously and improve the quality of medicinal materials. Compared with the lower ages, silkworm excrement of fifth instar seems like to be more suitable for use in medicine. Illumina MiSeq high throughput sequencing system provides a more accurate and scientific data resource for the study of bacteria in silkworm excrement.

AB - In this study,the content of ethanol extraction of agarwood were performed following the method of Chinese Pharmacopoeia(ChP 2015 edition). The chromatographic fingerprints were established by GC-MS. Similarity Evaluation System for Chromatographic Fingerprint of traditional Chinese medicine(TCM)(version 2012) was employed to calculate the similarity of each chromatogram of agarwood. The ratios of sum peak area in the range of 170-270 min and 0-100 min of individual chromatogram were calculated using square peaks to normalization. AMDIS and RI were employed to identify the common and different peaks. Correlation coefficient P(corr) combined with Variable important in projection(VIP) value was employed to screen the different representative components based on OPLS-DA analysis. Grey related degree and TOPSIS were used to evaluate the quality of artificial agarwoods. The results showed that more than 10.0% of the ethanol extract content was found in 15 batches of artificial agarwoods among the total 18. The similarity of 18 batches artificial agarwoods was 0.439-0.779. The peak area ratios of two intervals were in the range of 0.307 13.254. The 9 common components and 8 different components were identified. Meanwhile, 2% salicylic acid is the best inducer based on grey related degree and TOPSIS.

AB - This work was launched to explore the effect of habitat and growth year on the secondary metabolites contents of cultivated Polygala tenuifolia. The samples of cultivated P. tenuifolia were analyzed by ultra-high performance liquid chromatography(UPLC)-quadrupole time-of-flight mass spectrometry(Q-TOF MS), and the obtained data were analyzed using multiple statistical analysis and cluster analysis. The results showed that compared with growth year, habitat is a main influencing factor which affected the secondary metabolites contents of P. tenuifolia. The contents of sucrose esters and oligosacchride multi-esters are greatly dependent on the habitat (the sample-AG with high levels of components of tenuifoliside B and tenuifoliside C, and the sample-FY with high levels of 3,6' disinapoyl sucrose, tenuifoliose S, tenuifoliose L, and tenuifoliose V). There is no obvious effect of habitat and growth year on xanthone. The contents of triterpene saponins are greatly dependent on the growth year, and the content of parts of triterpene saponins increased as time goes on.The result indicated that the effect of habitat and growth year on different types of secondary metabolites is not completely equivalent. This study will contribute to the breeding of P. tenuifolia and amendment of current commodity criteria. PMID- 29171238 TI - [Investigation on stability and degradation kinetics of febrifugine]. AB - To investigate the stability and degradation kinetics of febrifugine. The results showed that within 24 hours, febrifugine content was decreased by only 1% in mobile phase solvent, but its content was decreased to be 90% of the initial content in the water, methanol, 50% methanol and 10% acetonitrile solution. When the pH value of the solution was between 3 and 7, the retention rate of febrifugine in 24 hours was over 98%, but its content was decreased by about 12% in alkaline solution (pH 9.0). The higher the temperature, the worse the stability of febrifugine. At 40-80 C, the content of febrifugine was decreased to be 60% of its initial content in 10 hours, but the content was decreased by only 5% in 10 h at 20 C.However, no matter 40 Cor 60 C, febrifugine was mainly transformed into isofebrifugine, and the total content of febrifugine and isofebrifugine was equal to their initial total content in 10 hours, while incase of 80 C, the total content was decreased to be 83.33% in 10 h, which suggested that the structure of febrifugine was absolutely changed, not just isomerized to be isofebrigugine at high temperature. Light had a significant impact on the stability of febrifugine. Under bright light, the content of febrifugine was reduced by about 23% in 108 h, but it only decreased by about 10% in the natural light or darkness. In artificial gastric fluid (pH 1.4) and artificial intestinal fluid (pH 6.8), the content of febrifugine was decreased by less than 5% in 10 h. After storage at high temperature(60 C), high humidity [(75+/-1)%] and strong light (3 000 lx) conditions for 10 d, the content of solid febrifugine was decreased by 0.27%, 7.6% and 5.39%, respectively. The degradation of febrifugine basically complied with the first-order reaction kinetic process in the following conditions: in water, methanol, 50%methanol and 10% acetonitrile solvents, alkaline solution (pH>7), different light intensity and different temperatures (20,40 C). Therefore, no matter the isolation and purification of febrifugine or the production of the related preparations, it should be done fast in the acidic solution, low temperature and dark conditions, while the febrifugine solid should be kept in dry and dark conditions.

AB - To study the inhibitory effect of butyl alcohol extract of Baitouweng decoction(BAEB) on Candida albicans cell membrane. The effects of BAEB on the activity of C. albicans were observed by Spot assay. The changes of intracellular osmotic pressure of C. albicans after BAEB intervention were detected by microtiter plate reader. The effect of BAEB on cell membrane permeability of C. albicans were observed by fluorescence microscopy. The content of ergosterol in C. albicans cell membrane was detected by high performance liquid chromatography, and the expression of ergosterol biosynthesis related genes in cell membrane was detected by qRT-PCR. The results showed that the activity of C. albicans was significantly decreased in 256, 512 and 1 024 mg*L-1 BAEB group. The intracellular glycerol content of C. albicans was significantly increased in 512 and 1 024 mg*L-1 BAEB group(P<0.05). The gene HOG1 associated with intracellular osmotic pressure of C. albicans was down-regulated by 9.1, 9.3 and 5.5 times, respectively. C. albicans with red fluorescent were increased significantly in 512 and 1 024 mg*L-1 BAEB group. The peak area of ergosterol in the 1 024 mg*L-1 BAEB group was 35.884 95, with a significant difference(P<0.05); ERG1, ERG2, ERG3, ERG4, ERG5, ERG6, ERG10, ERG11, ERG13, ERG24, ERG25, ERG251, ERG26 and UPC2 were down-regulated by 6.58, 4.89, 4.15, 9.24,3.41, 9.84, 3.08, 7.50, 5.53, 5.90, 2.45, 3.25,1.98 and 10.07 times respectively in 1 024 mg*L-1 BAEB group. The study indicated that BAEB could inhibit ergosterol and its biosynthesis related genes expression in the cell membrane and inhibit the activity of C. albicans.

AB - To explore the effect of leech on proliferation and apoptosis of vascular smooth muscle cells(VSMCs) in early atherosclerosis rats via p38MAPK signaling pathway and investigate its possible mechanism. Biochemical analyzer was used to examine the regulation of leech on levels of triglycerides(TG), total cholesterol(TC), low-density lipoprotein(LDL-C), and high-density lipoprotein(HDL-C) in blood lipid of rats. The expression of transforming growth factor-beta 1(TGF-beta1) in serum was detected by ELISA. Immunological histological chemistry (IHC) was taken to measure the expression levels of proliferating cell nucleus antigen(PCNA) and cell apoptosis proteinase-3(Caspase-3), while the protein expression levels of MKK3, p38 and C-myc were detected by Western blot. In addition, hematoxylin and eosin(HE) staining was used to observe the morphological change of thoracic aortas. The results showed that leech decreased the levels of TC, LDL-C obviously and increased HDL-C, suppressed the expression levels of TGF-beta1 and PCNA, up regulated Caspase-3, down-regulated the expression levels of MKK3, p38, and C-myc protein. HE staining indicated that it could inhibit intimal thickening and reduce plaque formation. The above results indicated that leech may affect the protein expression of the p38MAPK signaling pathway to inhibit proliferation and promote the apoptosis of VSMCs via reducing blood lipid levels and suppressing TGF-beta1, aiming at inhibiting intimal thickening and reducing plaque formation, tand then slowing down the process of early atherosclerosis. PMID- 29171241 TI - [Adverse reaction and screening of sensitizing substance of Shuxuening injection]. AB - In this study, by the means of the active systemic allergy test in guinea pigs, passive skin allergy test in rats and pseudoallergic test in mice, it was determined that the "allergic reaction" of Shuxuening injection(SXNI) may not be a true IgE-mediated allergic reactions, but mainly of pseudoallergic reaction. Further pseudoallergic test proved that the pseudoallergic reactions of SXNI had difference between batches and showed dose dependence, so it was recommended to establish SXNI pseudoallergic reaction detection method for timely detecting and controlling the product risk of each batch products. In addition, as the pseudoallergic reactions of SXNI were dose-dependent, the dose and concentration of SXNI should be strictly controlled in clinical use. Then the main pseudoallergenic reaction test was conducted for the main monomer components in SXNI and the different fractions of Ginkgo biloba extract in mice, and the results showed that the sensitizing substances may mainly exist in YXY-3 fractions containing flavonol glycosides. By further chemically separating YXY-3, we got four chemical components. Among these four components, YXY-3-1 and YXY-3-2 were testified as the main allergenic components in SXNI through pseudoallergic test in mice. To make sure the specific chemical constituent that is responsible for the pseudoallergic reaction, in-depth study in follow-up experiments should be needed.

AB - Tongmai formula (TMF) is a drug combination of three components including Puerariae Lobatae Radix [roots of Pueraria lobata], Salviae Miltiorrhizae Radix (roots of Salvia miltiorrhiza) and Chuanxiong Rhizoma (rhizomes of Ligusticum chuanxiong) in a weight ratio of 1?1?1. The absorption and transport of isoflavonoid compounds from Tongmai formula across human intestinal epithelial (Caco-2) cells in vitro were studied in this paper. The assay isoflavonoid compounds include daidzein, formononetin, 5-hydroxylononin, ononin, daidzin, 3' methoxypuerarin, genistin, puerarin, formononetin-8-C-beta-D-apiofuranosyl-(1->6) O-beta-D-glucopyranoside, formononetin-7-O-beta-D-apiofuranosyl-(1->6)-O-beta-D glucopyranoside, lanceolarin, kakkanin, daidzein-7,4'-di-O-beta-D glucopyranoside, mirificin, 3'-hydroxypuerarin, 3'-methoxydaidzin, formononetin-8 C-beta-D-xylopyranosyl-(1->6)-O-beta-D-glucopyranoside, genistein-8-C-beta-D apiofuranosyl-(1->6)-O-beta-D-glucopyranoside, genistein-7-O-beta-D-apiofuranosyl (1->6)-O-beta-D-glucopyranoside (ambocin), 3'-hydroxymirificin, 6"-O-beta-D xylosylpuerarin, biochanin A-8-C-beta-D-apiofuranosyl-(1->6)-O-beta-D glucopyranoside, 3'-methoxydaidzein-7,4'-di-O-beta-D-glucopyranoside, daidzein-7 O-beta-D-glucopyranosyl-(1->4)-O-beta-D-glucopyranoside, and daidzein-7-O-alpha-D glucopyranosyl-(1->4)-O-beta-D-glucopyranoside. By using human Caco-2 monolayer as an intestinal epithelial cell model in vitro, the permeability of above mentioned 25 isoflavonoids in TMF were studied from the apical (AP) side to basolateral (BL) side or from the BL side to AP side. The assay compounds were determined by reversed phased high-performance liquid chromatography (HPLC) coupled with UV detector. Transport parameters and apparent permeability coefficients (Papp) were then calculated and and compared with those of propranolol and atenolol, which are the transcellular transport marker and as a control substance for high and poor permeability, respectively. The Papp values of daidzein and formononetin were (2.55+/-0.03) *10-5,(3.06+/-0.01) *10-5 cm*s-1 from AP side to BL side, respectively, and (2.62+/-0.00) *10-5, (2.65+/-0.11) *10 5 cm*s-1 from BL side to AP side, respectively. Under the condition of this experiment, the Papp value was (2.66+/-0.32) *10-5 cm*s-1 for propranolol and (2.34+/-0.10) *10-7 cm*s-1 for atenolol. The Papp values of daidzein and formononetin were at a same magnitude with those of propranolol. And the Papp values of other 23 isoflavonoid compounds were at a same magnitude with those of atenolol. On the other hand, the rats of Papp AP->BL/Papp BL->AP of daidzein and formononetin on the influx transport were 0.97 and 1.15, respectively. It can be predicted that daidzein and formononetin can be absorbed across intestinal epithelial cells to go to the body circulation by the passive diffusion mechanism and they were assigned to the well-absorbed compounds. Other 23 isoflavonoid compounds were assigned to the poorly absorbed compounds. Because of the rats of Papp AP->BL/Papp BL->AP of 5-hydroxylononin, genistin, lanceolarin, kakkanin, and genistein-7-O-beta-D-apiofuranosyl-(1->6)-O-beta-D-glucopyranoside were 0.18, 0.28, 0.45, 0.38, 0.49, they may have been involved in the efflux mechanism in Caco-2 cells monolayer model from the BL side to AP side direction.

Through collection of the prescriptions, a total of 215 prescriptions were included, involving a total of 376 herbs. Through the "frequency statistics", the prescriptions containing Pterocephali Herba were commonly used to treat cold fever, distemper virus and arthritis. The highest frequently (frequency>=15) used drugs were Corydalis Herba, Lagotidis Herba, and Gentianae Macrophyllae Radix, et al. The most frequently used drug combinations were "Pterocephali Herba, Corydalis Herba","Pterocephali Herba, Lagotidis Herba", and "Pterocephali Herba, Gentianae Macrophyllae Radix" et al. The prescriptions containing Pterocephali Herba were used to primarily treat disease for Tourette syndrome caused by the dampness heat toxin, fever, arthritis etc, such as pestilent toxicity, pneumonia and influenza, rheumatoid arthritis etc. The drugs in the prescriptions mostly had the effects of heat-clearing and detoxifying, anti-inflammatory, dispelling wind and dampness, often in compatible use with heat-clearing drugs. The drug use was concentrated and reflected the clear thought of prescription statutes. PMID- 29171244 TI - [Identification of origin plant of Uygur medicine mulberry based on DNA barcode]. AB - To provide molecular evidence for medical material identification, we analyzed the nucleotide sequence of ITS2, psbA-trnH gene in Morus genus plants and commercial products which were obtained from different places in Xinjiang. The sequence of ITS2 and psbA-trnH in fifty-one samples were amplified and sequenced, MEGA 6.0 was used to analyze the intra- and interspecific K-2P distances, neighbor-joining (NJ) tree was used to constructing clustering tree. ITS2 sequence analyzed results showed that there is no intra-specific variation among Morus alba, M. alba var. tatarica and M. nigra, but 13 variations sites were exist between M. alba and M. nigra and their inter-specific K-2P distances was 0.04, which indicated that there had significant variation in them. We didn't find informative variation sites between Morus genus plants and commercial products, and we also found that M. nigra can be distinguished from other two species by NJ Tree. PsbA-trnH analysis results showed there was only one variation site between M. alba and M. nigra, but insertion or deletion variation were remarkable evidence among M. alba, M. alba var. tatarica and M. Nigra. Inter specific variation was accordance with intra-specific variation of commercial products. So ITS2 and psbA-trnH gene were important marker for M. alba, M. alba var. tatarica and M. nigra identification. This study provided important evidence for Uygur medicine identification and market supervision. PMID- 29171245 TI - [Origin of lifting and lowering theory and its herb pair study]. AB - Lifting and lowering theory is one of the important basis for guiding clinical medication. Through the study of ancient books and literature, we learned that lifting and lowering theory was originated in Huangdi Neijing, practiced more in the Shanghan Zabing Lun, established in Yixue Qiyuan, and developed in Compendium of Materia Medica and now. However, lifting and lowering theory is now mostly stagnated in the theoretical stage, with few experimental research. In the clinical study, the guiding role of lifting and lowering theory to prescriptions?mainly includes opposite?role?of lift and lower medicine property, mutual promotion of lift and lower medicine property, main role of lift medicine property and main role of lower medicine property. Under the guidance of lifting and lowering theory, the herb pair compatibility include herb combination of lift medicine property, herb combination of lift and lower medicine property and herb combination of lower medicine property. Modern biological technology was used in this study to carry out experimental research on the lifting and lowering theory, revealing the scientific connotation of it, which will help to promote clinical rational drug use. PMID- 29171246 TI - [Strategy of constructing post-market integral evaluation system of traditional Chinese medicine injection]. AB - As an important representative of modern Chinese medicine, traditional Chinese medicine (TCM) injzection has become an indispensable part of the Chinese medicine industry. However, its development is now restricted by the bottleneck of insufficient core competitiveness, low-level research and production, even injection quality and the safe use are not guaranteed. Thus, it is urgent to reevaluate post-marketing TCM injection generally and to make secondary development. Under current circumstances, taking major brands which have good clinical and market foundation, as well as research value, as the main subject of cultivation and evaluation is an important approach to innovative development of TCM injection industry. Unlike oral proprietary Chinese medicine, the cultivatation of major brands of TCM injection needs higher technical support, quality standards and more timely feedback. Therefore, a post-market integral evaluation system adaptive to TCM injection is required. This article discussed some key points on the construction of a post-market integral evaluation system of TCM injection in three levels: optimizing evaluation methods, building synergistic innovation platforms which combine the medical research institutions and pharmaceutical enterprises, and finally constructing the integral evaluation system. A "five to one" structure has been proposed to enhance TCM injection effectiveness, safety and adaptability on the whole, which are from the following aspects: mechanism research, clinical evidence validation, literature information mining, sustainable development of resources and industrialization operation.

AB - There are several reasons why mechanical ventilation - the use of an artificial device to assist a patient to breathe - may be initiated, for example to enable general anaesthesia for patients undergoing surgery, and for those with a compromised airway or respiratory failure. It is important that critical care nurses have the skills and knowledge to care for patients who are undergoing weaning from mechanical ventilation. This is to ensure that patients are weaned safely and as soon as possible, to improve their outcomes and avoid an increase in patient mortality and morbidity through complications that can arise such as airway trauma and ventilator-associated pneumonia. Furthermore, there are resource and cost implications of patients not being weaned as soon as possible. PMID- 29171248 TI - Methods of contraception: the nurse's role in providing care and advice. AB - Most women require contraception during their reproductive years, and many methods are available. Women should have access to all of these methods and be encouraged to take an active role in decision-making about their choice of contraceptive, within medical eligibility constraints. Long-acting reversible contraceptives are more effective than user-dependent methods, such as condoms, and should be offered to all women during contraceptive consultations. In primary care settings, nurses often provide much basic contraception care and advice. Nurses should ensure that they work within the limits of their competence and are aware of how and where to refer women for specialist support, if required. PMID- 29171249 TI - Chronic venous disease treated with sulodexide: a survey among primary care physicians in Mexico. AB - BACKGROUND: Sulodexide is a glycosaminoglycan approved for the treatment of chronic venous disease (CVD). It has been available in Mexico since 2012. The aim of the study was to understand the clinical experience of primary care physicians in the treatment of CVD with sulodexide. METHODS: Clinical data collection forms were distributed among general practitioners. Data was collected for up to four follow-up consultations. All signs and symptoms were rated with the Likert Scale at each examination: 0 to 5 (where 0 means none, and 5 very severe). Both the patient's and the physician's opinions of the effects of the treatment were recorded. RESULTS: Data were collected from 1599 patients at different clinical stages of CVD, 52% of which were at advanced stages (C4-C6). A total of 434 cases were followed up with four examinations (median of thirty days between each examination). In these cases, the overall sign and symptom score decreased significantly at each examination (P<0.01). At the fourth examination, 98.9% of the patients felt better or much better than at the first examination, and 99.7% were better or much better in the physician's opinion (P<0.01). The only adverse effect was nausea, reported in two cases. CONCLUSIONS: Sulodexide was effective and well tolerated in the treatment of CVD.

AB - Chip-scale chemical sensors were demonstrated using optical waveguides consisting of amorphous silicon (a-Si) and aluminum nitride (AlN). A mid-infrared (mid-IR) transparent AlN thin film was prepared by room-temperature sputtering, which exhibited high Al/N elemental homogeneity. The Si-on-AlN waveguides were fabricated by a complementary metal-oxide-semiconductor process. A sharp fundamental mode and low optical loss of 2.21 dB/cm were obtained. Label-free chemical identification and real-time monitoring were performed by scanning the mode spectrum while the waveguide was exposed to various chemicals. Continuous tracing of heptane and methanol was accomplished by measuring the waveguide intensity attenuation at lambda = 2.5-3.0 MUm, which included the characteristic CH and -OH absorptions. The monolithically integrated Si-on-AlN waveguides established a new sensor platform that can operate over a broad mid-IR regime, thus enabling photonic chips for label-free chemical detection.

AB - Generation of uniform emulsion droplets mixed with multiple components is one of the key issues in the field of lab in a drop. Traditionally, droplet microfluidic chips are often served as the prime choice while designing and fabricating microfluidic chips always rely on skilled technician and specialized equipment, severely restricting its wide accessibility. In this work, an alternative technique, called multichannel dynamic interfacial printing (MC-DIP), was proposed for multicomponent droplet generation. The MC-DIP device was designed modularly and could be set up manually without any microfabrication process, exhibiting full accessibility for freshmen after a brief training. This new technique owns advantages in the generation of droplets with predictable sizes and composites. Quantitative experiments of measuring minimum inhibitory concentration (MIC) value via mixing microbes and antibiotics into droplet were conducted to proving its application potential for lab in a drop. Further research on a clinical pathogenic strain revealed that this technique could be potentially applied in the clinical laboratory for antibiotic susceptibility testing. PMID- 29171253 TI - Can Carbamates Undergo Radical Oxidation in the Soil Environment? A Case Study on Carbaryl and Carbofuran. AB - Radical oxidation of carbamate insecticides, namely carbaryl and carbofuran, was investigated with spectroscopic (electron paramagnetic resonance [EPR] and UV vis) and theoretical (density functional theory [DFT] and ab initio orbital optimized spin-component scaled MP2 [OO-SCS-MP2]) methods. The two carbamates were subjected to reaction with *OH, persistent DPPH* and galvinoxyl radical, as well as indigenous radicals of humic acids. The influence of fulvic acids on carbamate oxidation was also tested. The results obtained with EPR and UV-vis spectroscopy indicate that carbamates can undergo direct reactions with various radical species, oxidizing themselves into radicals in the process. Hence, they are prone to participate in the prolongation step of the radical chain reactions occurring in the soil environment. Theoretical calculations revealed that from the thermodynamic point of view hydrogen atom transfer is the preferred mechanism in the reactions of the two carbamates with the radicals. The activity of carbofuran was determined experimentally (using pseudo-first-order kinetics) and theoretically to be noticeably higher in comparison with carbaryl and comparable with gallic acid. The findings of this study suggest that the radicals present in soil can play an important role in natural remediation mechanisms of carbamates. PMID- 29171254 TI - Near-Infrared-to-Ultraviolet Light-Mediated Photoelectrochemical Aptasensing Platform for Cancer Biomarker Based on Core-Shell NaYF4:Yb,Tm@TiO2 Upconversion Microrods. AB - Titanium dioxide (TiO2; as a potential photosensitizer) has good photocurrent performance and chemical stability but often exhibits low utilization efficiency under ultraviolet (UV) region excitation. Herein, we devised a near-infrared light-to-UV light-mediated photoelectrochemical (PEC) aptasensing platform for the sensitive detection of carcinoembryonic antigen (CEA) based on core-shell NaYF4:Yb,Tm@TiO2 upconversion microrods by coupling with target-triggered rolling circle amplification (RCA). The upconversion microrods synthesized through the hydrothermal reaction could act as a photosensing platform to convert the near infrared (near-IR) excitation into UV emission for generation of photoinduced electrons. The target analyte was determined on a functional magnetic bead by using the corresponding aptamers with a sandwich-type assay format. Upon target CEA introduction, a complex was first formed between capture aptamer-1-conjugated magnetic bead (Apt1-MB) and aptamer-2-primer DNA (Apt2-pDNA). Thereafter, the carried primer DNA by the aptamer-2 paired with linear padlock DNA to trigger the RCA reaction. The guanine (G)-rich product by RCA reaction was cleaved by exonuclease I and exonuclease III (Exos I/III), thereby resulting in the formation of numerous individual guanine bases to enhance the photocurrent of core-shell NaYF4:Yb,Tm@TiO2 upconversion microrods under near-IR illumination (980 nm). Under optimal conditions, the near-IR light-mediated PEC aptasensing system could exhibit good photoelectrochemical response toward target CEA and allowed for the detection of target CEA as low as 3.6 pg mL-1. High reproducibility and good accuracy were achieved for analysis of human serum specimens. Importantly, the near-IR-activated PEC aptasensing scheme provides a promising platform for ultrasensitive detection of other biomolecules.

AB - Controlling spin dynamics through modulation of spin interactions in a fast, compact, and energy-efficient way is compelling for its abundant physical phenomena and great application potential in next-generation voltage controllable spintronic devices. In this work, we report electric field manipulation of spin dynamics-the two-magnon scattering (TMS) effect in Ni0.5Zn0.5Fe2O4 (NZFO)/Pb(Mg2/3Nb1/3)-PbTiO3 (PMN-PT) multiferroic heterostructures, which breaks the bottleneck of magnetostatic interaction-based magnetoelectric (ME) coupling in multiferroics. An alternative approach allowing spin-wave damping to be controlled by external electric field accompanied by a significant enhancement of the ME effect has been demonstrated. A two-way modulation of the TMS effect with a large magnetic anisotropy change up to 688 Oe has been obtained, referring to a 24 times ME effect enhancement at the TMS critical angle at room temperature. Furthermore, the anisotropic spin-freezing behaviors of NZFO were first determined via identifying the spatial magnetic anisotropy fluctuations. A large spin-freezing temperature change of 160 K induced by the external electric field was precisely determined by electron spin resonance. PMID- 29171256 TI - Combination of Redox Assembly and Biomimetic Mineralization To Prepare Graphene Based Composite Cellular Foams for Versatile Catalysis. AB - Graphene-based materials with hierarchical structures and multifunctionality have gained much interest in a variety of applications. Herein, we report a facile, yet universal approach to prepare graphene-based composite cellular foams (GCCFs) through combination of redox assembly and biomimetic mineralization enabled by cationic polymers. Specifically, cationic polymers (e.g., polyethyleneimine, lysozyme, etc.) could not only reduce and simultaneously assemble graphene oxide (GO) into cellular foams but also confer the cellular foams with mineralization inducing capability, enabling the formation of inorganic nanoparticles (e.g., silica, titania, silver, etc.). The GCCFs show highly porous structure and appropriate structural stability, where nanoparticles are well distributed on the surface of the reduced GO. Through altering polymer/inorganic pairs, a series of GCCFs are synthesized, which exhibit much enhanced catalytic performance in enzyme catalysis, heterogeneous chemical catalysis, and photocatalysis compared to nanoparticulate catalysts. PMID- 29171257 TI - Stereoselective Synthesis of Bicyclo[6.1.0]nonene Precursors of the Bioorthogonal Reagents s-TCO and BCN. AB - The cyclooctyne BCN and the trans-cyclooctene s-TCO are widely used in bioorthogonal chemistry. A bottleneck for their synthesis had been a poorly selective cyclopropanation with ethyl diazoacetate. Here, we describe that low catalyst loadings (0.27 mol %) of Rh2( S-BHTL)4 provide the BCN precursor with 79:21 syn/ anti selectivity. The synthesis of the s-TCO precursor was best achieved through a sequence of Rh2(OAc)4 (0.33 mol %)-catalyzed cyclopropanation, followed by ester hydrolysis under epimerizing conditions. Both sequences could be carried out on multigram scale. PMID- 29171258 TI - Construction of Plasmonic Ag and Nitrogen-Doped Graphene Quantum Dots Codecorated Ultrathin Graphitic Carbon Nitride Nanosheet Composites with Enhanced Photocatalytic Activity: Full-Spectrum Response Ability and Mechanism Insight. AB - The full utilization of solar energy has attracted great attention in the photocatalysis and environmental pollutant control. In this study, the local surface plasmon resonance effect of Ag nanoparticles (Ag NPs) with the upconversion property of nitrogen-doped graphene quantum dots (N-GQDs) was first combined for the formation of ternary Ag/N-GQDs/g-C3N4 nanocomposites. The prepared material presents enhanced full-spectrum light response ability, even in near-infrared (NIR) light. The experiment results disclosed that the 0.5% N-GQDs and 2.0% Ag NPs co-doped g-C3N4 show the highest photocatalytic activity, achieving 92.8 and 31.3% removal efficiency under full-spectrum light and NIR light irradiation, respectively, which was three-fold than that of pristine g C3N4. The boosted photocatalytic activity can be attributed to the synergistic effect among the g-C3N4, N-GQDs, and Ag NPs. The g-C3N4 nanosheets can serve as the reaction matrix and support for the dispersion of N-GQDs and Ag NPs, inhibiting their agglomeration. The existence of Ag NPs and N-GQDs can promote the light absorption and transfer ability, leading to the generation of more photoinduced charges. Simultaneously, N-GQDs and Ag NPs can efficiently transfer and reserve electrons, which can accelerate the photoinduced electrons' migration, inhibiting the recombination. The comprehensive effect of the reasons mentioned above resulted in the unique photocatalytic activity of the prepared Ag/N-GQDs/g-C3N4 nanocomposites. This study provides a new strategy for the formation of highly efficient photocatalysts with broad-spectrum light response ability and the potential for realistic wastewater pollution control. PMID- 29171259 TI - Label-Free and Recalibrated Multilayer MoS2 Biosensor for Point-of-Care Diagnostics. AB - Molybdenum disulfide (MoS2) field-effect transistor (FET)-based biosensors have attracted significant attention as promising candidates for highly sensitive, label-free biomolecule detection devices. In this paper, toward practical applications of biosensors, we demonstrate reliable and quantitative detection of a prostate cancer biomarker using the MoS2 FET biosensor in a nonaqueous environment by reducing nonspecific molecular binding events and realizing uniform chemisorption of anti-PSA onto the MoS2 surface. A systematic and statistical study on the capability of the proposed device is presented, and the biological binding events are directly confirmed and characterized through intensive structural and electrical analysis. Our proposed biosensor can reliably detect various PSA concentrations with a limit of 100 fg/mL. Moreover, rigorous theoretical simulations provide a comprehensive understanding of the operating mechanism of the MoS2 FET biosensors, and further suggests the enhancement of the sensitivity through engineering device design parameters. PMID- 29171260 TI - Engineering the Photoresponse of InAs Nanowires. AB - We report on individual-InAs nanowire optoelectronic devices which can be tailored to exhibit either negative or positive photoconductivity (NPC or PPC). The NPC photoresponse time and magnitude is found to be highly tunable by varying the nanowire diameter under controlled growth conditions. Using hysteresis characterization, we decouple the observed photoexcitation-induced hot electron trapping from conventional electric field-induced trapping to gain a fundamental insight into the interface trap states responsible for NPC. Furthermore, we demonstrate surface passivation without chemical etching which both enhances the field-effect mobility of the nanowires by approximately an order of magnitude and effectively eliminates the hot carrier trapping found to be responsible for NPC, thus restoring an "intrinsic" positive photoresponse. This opens pathways toward engineering semiconductor nanowires for novel optical-memory and photodetector applications. PMID- 29171261 TI - Aggregation-Induced Enhanced Electrochemiluminescence from Organic Nanoparticles of Donor-Acceptor Based Coumarin Derivatives. AB - Organic nanoparticles (NPs) from donor-acceptor based coumarin derivatives, 6-[4 (N,N-diphenylamino)phenyl]-3-ethoxycarbonyl coumarin (DPA-CM), with an average size of 5.82 nm, were synthesized by a facile reprecipitation method using water as a poor solvent and tetrahydrofuran as a good solvent. Red-shifted absorption, blue-shifted photoluminescence emission, and aggregation-induced enhanced electrochemiluminescence (ECL) emission were observed for the DPA-CM NPs in aqueous solution compared with the original DPA-CM in organic solution. The aggregation-induced enhanced ECL emission is ascribed to the combined effects of the small size of the DPA-CM NPs, the restricted conformational relaxation in the NPs, and the good stability of the cationic radical of DPA-CM. A strong and stable ECL emission is obtained at the DPA-CM NPs modified glassy carbon electrode in the presence of tri-n-propylamine, and the ECL intensity of the DPA CM NPs modified electrode is quenched linearly in the range of 0.05-50 MUM with detection limit of 0.04, 0.2, and 0.4 MUM for ascorbic acid, uric acid, and dopamine, respectively. This work shows an example of donor-acceptor based organic NPs as ECL emitters and their analytical applications to monitor biomolecules. PMID- 29171262 TI - High-Yield and Sustainable Production of Phosphatidylserine in Purely Aqueous Solutions via Adsorption of Phosphatidylcholine on Triton-X-100-Modified Silica. AB - Triton X-100 was covalently bound to a surface of silica and acted as an anchor molecule to facilitate the adsorption of phosphatidylcholine (PC) in a purely aqueous solution. The silica-adsorbed PC obtained was successfully used for phospholipase D (PLD)-mediated transphosphatidylation in the production of phosphatidylserine (PS). Organic solvents were completely avoided in the whole production process. The PC loading and PS yield reached 98.9 and 99.0%, respectively. Two adsorption models were studied, and the relevant parameters were calculated to help us understand the adsorption and reaction processes deeply. In addition, the silica-adsorbed PC provides a promising way to continuously biosynthesize PS. A packed-bed reactor was employed to demonstrate the process flow of the continuous production of PS. The recyclability and stability of the Triton-X-100-modified silica were excellent, as demonstrated by its use 30 times during continuous operation without any loss of the productivity. PMID- 29171263 TI - A Small Molecule Nanodrug by Self-Assembly of Dual Anticancer Drugs and Photosensitizer for Synergistic near-Infrared Cancer Theranostics. AB - Phototherapy including photodynamic therapy (PDT) and photothermal therapy (PTT) has attracted great attention. However, applications of some photosensitizers remain an obstacle by their poor photostability. To enhance the treatment efficiency of photosensitizers and tumor theranostic effect, herein, we reported a novel carrier-free, theranostic nanodrug by self-assembly of small molecule dual anticancer drugs and photosensitizer for tumor targeting. The developed carrier-free small molecule nanodrug delivery system was formed by hydrophobic ursolic acid, paclitaxel, and amphipathic indocyanine green (ICG) associated with electrostatic, pi-pi stacking, and hydrophobic interactions exhibiting water stability. The self-assembling of ICG on the dual anticancer nanodrug significantly enhanced water solubility of hydrophobic anticancer drugs and ICG photostability contributing to long-term near-infrared (NIR) fluorescence imaging and effective chemophototherapy of tumor. The in vivo NIR fluorescence imaging showed that the theranostic nanodrug could be targeted to the tumor site via a potential enhanced permeability and retention effect proving the efficient accumulation of nanoparticles in the tumor site. Dramatically, chemophototherapy of tumor-bearing mice in vivo almost completely suppressed tumor growth and no tumor recurrence was observed. Encouraged by its carrier-free, prominent imaging and effective therapy, the small molecule nanodrug via self-assembly will provide a promising strategy for synergistic cancer theranostics. PMID- 29171264 TI - Radiopaque Resists for Two-Photon Lithography To Enable Submicron 3D Imaging of Polymer Parts via X-ray Computed Tomography. AB - Two-photon lithography (TPL) is a high-resolution additive manufacturing (AM) technique capable of producing arbitrarily complex three-dimensional (3D) microstructures with features 2-3 orders of magnitude finer than human hair. This process finds numerous applications as a direct route toward the fabrication of novel optical and mechanical metamaterials, miniaturized optics, microfluidics, biological scaffolds, and various other intricate 3D parts. As TPL matures, metrology and inspection become a crucial step in the manufacturing process to ensure that the geometric form of the end product meets design specifications. X ray-based computed tomography (CT) is a nondestructive technique that can provide this inspection capability for the evaluation of complex internal 3D structure. However, polymeric photoresists commonly used for TPL, as well as other forms of stereolithography, poorly attenuate X-rays due to the low atomic number (Z) of their constituent elements and therefore appear relatively transparent during imaging. Here, we present the development of optically clear yet radiopaque photoresists for enhanced contrast under X-ray CT. We have synthesized iodinated acrylate monomers to formulate high-Z photoresist materials that are capable of forming 3D microstructures with sub-150 nm features. In addition, we have developed a formulation protocol to match the refractive index of the photoresists to the immersion medium of the objective lens so as to enable dip-in laser lithography, a direct laser writing technique for producing millimeter-tall structures. Our radiopaque photopolymer resists increase X-ray attenuation by a factor of more than 10 times without sacrificing the sub-150 nm feature resolution or the millimeter-scale part height. Thus, our resists can successfully replace existing photopolymers to generate AM parts that are suitable for inspection via X-ray CT. By providing the "feedstock" for radiopaque AM parts, our resist formulation is expected to play a critical role in enabling fabrication of functional polymer parts to tight design tolerances.

AB - We demonstrate that particle-particle interaction affects the photocatalytic efficiency of colloids.

PMID- 29171266 TI - Toward a Unified Total Synthesis of the Xiamycin and Oridamycin Families of Indolosesquiterpenes. AB - A unified synthetic strategy toward the oridamycin and xiamycin families of natural products was designed, aiming to access several natural products from a common synthetic intermediate readily prepared from geranyl acetate. Part of this strategy was successfully realized, culminating in the synthesis of oridamycin A and oridamycin B. Key steps include a Mn(III)-mediated oxidative radical cyclization to construct the trans-decalin ring, and a 6pi electrocyclization/aromatization sequence to produce the 2,3-fused carbazole. Oridamycin B was accessed through a late-stage, C-H oxidation that converted the C16 methyl to a hydroxymethyl. A variety of strategies were explored to form a chelated radical intermediate en route to xiamycin A, including enolate SET oxidation, oxo-vanadium oxidation, and atom-transfer cyclization. Unfortunately, none of these strategies provided the desired C16-epimeric trans-decalin. Exploratory studies on photoredox-catalyzed radical cyclizations yielded interesting results, including the formation of a bicyclic lactone arising from oxidative termination of the photoredox-catalyzed radical cyclization, and a double 6-endo cyclization with catalyst loadings as low as 0.01 mol%. PMID- 29171267 TI - UHPLC-Q-TOF-MS/MS Method Based on Four-Step Strategy for Metabolism Study of Fisetin in Vitro and in Vivo. AB - Fisetin has been identified as an anticancer agent with antiangiogenic properties in mice. However, its metabolism in vitro (rat liver microsomes) and in vivo (rats) is presently not characterized. In this study, ultra-high-performance liquid chromatography coupled with hybrid triple quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS) was employed for data acquiring, and a four-step analytical strategy was developed to screen and identify metabolites. First, full scan was applied, which was dependent on a multiple mass defect filter (MMDF) combined with dynamic background subtraction (DBS). Then PeakView 1.2 and Metabolitepilot 1.5 software were used to load data to seek possible metabolites. Finally, metabolites were identified according to mass measurement and retention time. Moreover, isomers were distinguished based on Clog P parameter. Based on the proposed method, 53 metabolites in vivo and 14 metabolites in vitro were characterized. Moreover, metabolic pathways mainly included oxidation, reduction, hydrogenation, methylation, sulfation, and glucuronidation. PMID- 29171268 TI - Quantification of Gold Nanoparticle Ultraviolet-Visible Extinction, Absorption, and Scattering Cross-Section Spectra and Scattering Depolarization Spectra: The Effects of Nanoparticle Geometry, Solvent Composition, Ligand Functionalization, and Nanoparticle Aggregation. AB - Using the recent polarized resonance synchronous spectroscopic (PRS2) technique, we reported the quantification of photon extinction, absorption, scattering cross section spectra, and scattering depolarization spectra for AuNPs of different sizes and shapes. The effects of the solvent composition, ligand functionalization, and nanoparticle aggregation on the AuNP photon absorption and scattering have also been experimentally quantified. The light scattering depolarization is close to 0 for gold nanospheres (AuNSs) crossing the entire UV vis region but is strongly wavelength-dependent for gold nanorods (AuNRs). Increasing the dielectric constant of the medium surrounding AuNPs either by solvents or ligand adsorption increases photon absorption and scattering but has no significant impact on the AuNP scattering depolarization. Nanoparticle aggregation increases AuNP photon scattering. However, even the extensively aggregated AuNPs remain predominantly photon absorbers with photon scattering-to extinction ratios all less than 0.03 for the investigated AuNP aggregates at the AuNP peak extinction wavelength. The AuNP scattering depolarization initially increases with the AuNP aggregation but decreases when aggregation further progresses. The insights from this study are important for a wide range of AuNP applications that involve photon/matter interactions, while the provided methodology is directly applicable for experimental quantification of optical properties for nanomaterials that are commonly simultaneously photon absorbers and scatterers.

AB - A fluorescence "turn-off" probe has been designed and successfully applied to detect cyanide (CN-) based on a Michael-type nucleophilic addition reaction and intramolecular charge transfer (ICT) mechanism. For this research, a family of 3 aryl-4-(2,2-dicyanovinyl)-1-(2-pyridinyl)pyrazoles as donor-pi-acceptor (D-pi-A) systems have been synthesized in 58-66% overall yield, by a three-step synthesis sequence starting from p-substituted acetophenones. The substituted p methoxyphenyl showed good fluorescence emission and large Stokes shifts in different solvents due to its greater ICT. Likewise, this probe evidenced high selectivity and sensitivity and fast recognition for CN- with a detection limit of 6.8 MUM. HRMS analysis, 1H NMR titration experiments, and TD-DFT calculations were performed to confirm the mechanism of detection and fluorescence properties of the chemodosimeter of CN-. Additionally, fluorescent test paper was conveniently used to detect cyanide in aqueous solution. PMID- 29171270 TI - Genetically Encoded Chemical Decaging in Living Bacteria. AB - We report the genetically encoded chemical decaging strategy for protein activation in living bacterial cells. In contrast to the metabolically labile photocaging groups inside Escherichia coli, our chemical decaging strategy that relies on the inverse electron-demand Diels-Alder (iDA) reaction is compatible with the intracellular environment of bacteria, which can be a general tool for gain-of-function study of a given protein in prokaryotic systems. By applying this strategy for in situ activation of the indole-producing enzyme TnaA, we built an orthogonal and chemically inducible indole production pathway inside E. coli cells, which revealed the role of indole in bacterial antibiotic tolerance. PMID- 29171271 TI - Biosynthetic Pathway and Metabolic Engineering of Plant Dihydrochalcones. AB - Dihydrochalcones are plant natural products containing the phenylpropanoid backbone and derived from the plant-specific phenylpropanoid pathway. Dihydrochalcone compounds are important in plant growth and response to stresses and, thus, can have large impacts on agricultural activity. In recent years, these compounds have also received increased attention from the biomedical community for their potential as anticancer treatments and other benefits for human health. However, they are typically produced at relatively low levels in plants. Therefore, an attractive alternative is to express the plant biosynthetic pathway genes in microbial hosts and to engineer the metabolic pathway/host to improve the production of these metabolites. In the present review, we discuss in detail the functions of genes and enzymes involved in the biosynthetic pathway of the dihydrochalcones and the recent strategies and achievements used in the reconstruction of multi-enzyme pathways in microorganisms in efforts to be able to attain higher amounts of desired dihydrochalcones.

AB - In this study, a new materials platform, utilizing the amorphous microstructure of bulk metallic glasses (BMGs) and the versatility of ion implantation, was developed for the fundamental investigation of cell responses to substrate rigidity variations in the gigapascal modulus range, which was previously unattainable with polymeric materials. The surface rigidity of a Zr-Al-Ni-Cu-Y BMG was modulated with low-energy Ar-ion implantation because of the impartment of Ar nanobubbles into the amorphous matrix. Surface softening was achieved due to the formation of nanobubble-doped transitional zones in the Zr-based BMG substrate. Bone-forming cell studies on this newly designed platform demonstrated that mechanical cues, accompanied by the potential effects of other surface properties (i.e., roughness, morphology, and chemistry), contributed to modulating cell behaviors. Cell adhesion and actin filaments were found to be less established on less stiff surfaces, especially on the surface with an elastic modulus of 51 GPa. Cell growth appeared to be affected by surface mechanical properties. A lower stiffness was generally related to a higher growth rate. Findings in this study broadened our fundamental understanding concerning the mechanosensing of bone cells on stiff substrates. It also suggests that surface mechanoengineering of metallic materials could be a potential strategy to promote osseointegration of such materials for bone-implant applications. Further investigations are proposed to fine-tune the ion implantation variables in order to further distinguish the surface-mechanical effect on bone-forming cell activities from the contributions of other surface properties.

AB - The analysis of oral fluid (OF) and urine samples to detect drug consumption has garnered considerable attention as alternative biomatrices. Efficient implementation of microextraction and ambient ionization technologies for rapid detection of target compounds in such biomatrices creates a need for biocompatible devices which can be implemented for in vivo sampling and easily interfaced with mass spectrometry (MS) analyzers. This study introduces a novel solid-phase microextraction-transmission mode (SPME-TM) device made of poly(etheretherketone) (PEEK) mesh that can rapidly detect prohibited substances in biofluids via direct analysis in real-time tandem MS (DART-MS/MS). PEEK mesh was selected due to its biocompatibility, excellent resistance to various organic solvents, and its ability to withstand relatively high temperatures (<=350 degrees C). The meshes were coated with hydrophilic-lipophilic-balance particle poly(acrylonitrile) (HLB-PAN) slurry. The robustness of the coated meshes was tested by performing rapid vortex agitation (>=3200 rpm) in LC/MS-grade solvents and by exposing them to the DART source jet stream at typical operational temperatures (~250-350 degrees C). PEEK SPME-TM devices proved to be robust and were therefore used to perform ex vivo analysis of drugs of abuse spiked in urine and OF samples. Excellent results were obtained for all analytes under study; furthermore, the tests yielded satisfactory limits of quantitation (median, ~0.5 ng mL-1), linearity (>=0.99), and accuracy (80-120%) over the evaluated range (0.5-200 ng mL-1). This research highlights plastic SPME-TM's potential usefulness as a method for rapidly screening for prohibited substances in on site/in vivo scenarios, such as roadside or workplace drug testing, antidoping controls, and pain management programs. PMID- 29171274 TI - Spontaneous Lipid Nanodisc Fomation by Amphiphilic Polymethacrylate Copolymers. AB - There is a growing interest in the use of lipid bilayer nanodiscs for various biochemical and biomedical applications. Among the different types of nanodiscs, the unique features of synthetic polymer-based nanodiscs have attracted additional interest. A styrene-maleic acid (SMA) copolymer demonstrated to form lipid nanodiscs has been used for structural biology related studies on membrane proteins. However, the application of SMA polymer based lipid nanodiscs is limited because of the strong absorption of the aromatic group interfering with various experimental measurements. Thus, there is considerable interest in the development of other molecular frameworks for the formation of polymer-based lipid nanodiscs. In this study, we report the first synthesis and characterization of a library of polymethacrylate random copolymers as alternatives to SMA polymer. In addition, we experimentally demonstrate the ability of these polymers to form lipid bilayer nanodiscs through the fragmentation of lipid vesicles by means of light scattering, electron microscopy, differential scanning calorimetry, and solution and solid-state NMR experiments. We further demonstrate a unique application of the newly developed polymer for kinetics and structural characterization of the aggregation of human islet amyloid polypeptide (also known as amylin) within the lipid bilayer of the polymer nanodiscs using thioflavin-T-based fluorescence and circular dichroism experiments. Our results demonstrate that the reported new styrene-free polymers can be used in high-throughput biophysical experiments. Therefore, we expect that the new polymer nanodiscs will be valuable in the structural studies of amyloid proteins and membrane proteins by various biophysical techniques. PMID- 29171276 TI - Pericardial effusion following cardiac surgery. A single-center experience. AB - Background Pericardial effusion is still a common postoperative complication after open heart surgery with cardiopulmonary bypass. Pericardial effusion significantly prolongs the hospital stay and associated costs as well as affecting overall outcomes after open heart surgery in Hanoi Heart Hospital, a tertiary hospital in Vietnam with an annual volume of 1000 patients. This study aimed to investigate the clinical presentation, incidence, and risk factors of postoperative pericardial effusion, which may ensure better prevention of pericardial effusion and improvement in surgical outcomes after open heart surgery. Methods A cross-sectional study was performed on 1127 patients undergoing open heart surgery from January 2015 to December 2015. Results Thirty six (3.19%) patients developed pericardial effusion. Of these, 16 (44.4%) had cardiac tamponade. Pericardial effusion occurred after valve procedures in 77.8% of cases. Pericardial effusion was detected after discharge in 47.2% of cases at a mean time of 18.1 +/- 13.7 days. Univariate logistic regression analysis showed that age > 25 years, body surface area >= 1.28 m2, preoperative liver dysfunction, New York Heart Association class III/IV, left ventricular end diastolic diameter z score >= 0.55, and postoperative anticoagulant use were associated with postoperative pericardial effusion. Multivariate logistic regression analysis showed that left ventricular end-diastolic diameter z score >= 0.55 was an independent risk factor for postoperative pericardial effusion. Conclusions Routine postoperative echocardiography is necessary to detect postoperative pericardial effusion. Increased left ventricular end-diastolic dimension is an independent predictor of postoperative pericardial effusion. PMID- 29171277 TI - Corrigendum.

AB - The aim of this study was to identify which employees' sociodemographic characteristics and personality traits affected their career development. The research was conducted on a sample of 462 employees, aged between 30 and 55. The final analysis of covariance model included only characteristics which had previously been identified as having significant effect and relations with career development: gender, age, education level, years of work experience with the current employer, total years of work experience, financial status, and all Big Five traits. It was determined that the following characteristics had a significant effect on career development: gender, years of work experience with the current employer, and financial status, from the set of sociodemographic characteristics, as well as Conscientiousness, from the personality traits. Sociodemographic characteristics and personality traits, especially Conscientiousness, represent significant determinants in career development.

AB - BACKGROUND: The Food and Drug Administration (FDA)'s Center for Food Safety and Applied Nutrition (CFSAN) oversees the safety of the nation's foods, dietary supplements, and cosmetic products. OBJECTIVE: To present a descriptive analysis of the 2004-2013 dietary supplement adverse event report (AER) data from CAERS and evaluate the 2006 Dietary Supplements and Nonprescription Drug Consumer Protection Act as pertaining to dietary supplements adverse events reporting. METHODS: We queried CAERS for data from the 2004-2013 AERs specifying at least 1 suspected dietary supplement product. We extracted the product name(s), the symptom(s) reported, age, sex, and serious adverse event outcomes. We examined time trends for mandatory and voluntary reporting and performed analysis using SAS v9.4 and R v3.3.0 software. RESULTS: Of the total AERs (n = 15 430) received from January 1, 2004, through December 31, 2013, indicating at least 1 suspected dietary supplement product, 66.9% were mandatory, 32.2% were voluntary, and 0.9% were both mandatory and voluntary. Reported serious outcomes included death, life threatening conditions, hospitalizations, congenital anomalies/birth defects and events requiring interventions to prevent permanent impairments (5.1%). The dietary supplement adverse event reporting rate in the United States was estimated at ~2% based on CAERS data. CONCLUSIONS: This study characterizes CAERS dietary supplement adverse event data for the 2004-2013 period and estimates a reporting rate of 2% for dietary supplement adverse events based on CAERS data. The findings show that the 2006 Dietary Supplements and Nonprescription Drug Consumer Protection Act had a substantial impact on the reporting of adverse events. PMID- 29171280 TI - An analysis of integrated health care for Internet Use Disorders in adolescents and adults. AB - Background and aims Although first treatment approaches for Internet Use Disorders (IUDs) have proven to be effective, health care utilization remained low. New service models focus on integrated health care systems, which facilitate access and reduce burdens of health care utilization, and stepped-care interventions, which efficiently provide individualized therapy. Methods An integrated health care approach for IUD intended to (a) be easily accessible and comprehensive, (b) cover a variety of comorbid syndromes, and (c) take heterogeneous levels of impairment into account was investigated in a one-armed prospective intervention study on n = 81 patients, who were treated from 2012 to 2016. Results First, patients showed significant improvement in Compulsive Internet Use over time, as measured by hierarchical linear modeling. Effect sizes of outcome change from baseline to 6-month follow-up ranged from d = 0.48 to d = 1.46. Second, differential effects were found depending on patients' compliance, demonstrating that high compliance resulted in significantly higher rates of change. Third, patients referred to minimal interventions did not differ significantly in amount of change from patients referred to intensive psychotherapy. Discussion Tailored interventions result in higher efficiency through optimized resource allocation and equal amounts of symptom change in all treatment conditions. Moreover, comprehensive, low-threshold interventions seem to increase health service utilization. PMID- 29171281 TI - Complete Malleus Removal for Cholesteatoma: A Multivariate Analysis of Ossiculoplasty Success and Residual Disease. AB - OBJECTIVE: Determine the effect of complete malleus removal during canal wall up tympanomastoidectomy for cholesteatoma on ossiculoplasty success and rate of residual cholesteatoma. METHODS: We reviewed the operative, audiogram, and clinical reports of patients who underwent canal wall up tympanomastoidectomy for cholesteatoma between 2009 and 2016 at a tertiary academic medical center with at least 8 months of follow-up after surgery. To control for extent of disease, we independently catalogued the subsites of the middle ear and mastoid that cholesteatoma involved from each operation. We performed multivariate logistic regression to determine the independent effect of complete removal of the malleus on the rate of residual disease and success of ossiculoplasty. RESULTS: One hundred eighty surgeries were included in the analysis. For ossiculoplasty success, the adjusted odds ratio of complete malleus removal was 1.7 (95% CI, 0.43-7.0, P = .43), which was not statistically significant. For residual disease, the adjusted odds ratio of complete malleus removal versus not was 0.29 (95% CI, 0.074-1.1, P = .076), which approached but did not meet statistical significance. CONCLUSION: Though complete malleus removal does not independently decrease the rate of residual cholesteatoma, it may be a safe technique as it did not compromise ossiculoplasty success. PMID- 29171282 TI - (3R)-5,6,7-trihydroxy-3-isopropyl-3-methylisochroman-1-one alleviates lipoteichoic acid-induced photoreceptor cell damage. AB - OBJECTIVE: Exposure to oxidative stress will lead to the progression of retinal degenerative diseases, and unfortunately the exact mechanisms have not been fully understood. In this study, the protective effects of (3R)-5,6,7-trihydroxy-3 isopropyl-3-methylisochroman-1-one (TIM) against the lipoteichoic acid (LTA) induced cell damage in mouse photoreceptor-derived 661W cells were investigated. METHODS: 661W cells were pre-treated with TIM at different concentrations (0.1 2.5 MUM) before exposure to LTA. The oxidative stress and inflammatory response were detected in 661W cells. RESULTS: Pre-treatment of 661W cells with TIM (0.1 2.5 MUM) for 4 h significantly decreased the LTA-induced toxicity. Meanwhile, pre treatment with TIM could attenuate the imbalance state of redox in 661W cells by decreasing the levels of intracellular ROS and MDA, as well as enhancing the SOD activity and the level of GSH, through increasing the protein expression of Nrf2. Moreover, TIM pre-treatment decreased pro-inflammatory factors IL-1beta, IL-12 and TNFalpha, through inhibiting the nuclear factor kappa B. Pre-treatment with TIM also suppressed Egr1, Fosl1, and Lox12 gene expression. CONCLUSION: These results suggested that TIM may exert its protective effects against LTA-induced toxicity in 661W cells, through counteracting the oxidative stress and inhibiting inflammatory response. Our findings provided the scientific rational to develop TIM in the treatment of oxidative stress-induced photoreceptor cell damage. PMID- 29171283 TI - Weightbearing Computed Tomography of the Foot and Ankle: Emerging Technology Topical Review. AB - : In the last decade, cone-beam computed tomography technology with improved designs allowing flexible gantry movements has allowed both supine and standing weight-bearing imaging of the lower extremity. There is an increasing amount of literature describing the use of weightbearing computed tomography in patients with foot and ankle disorders. To date, there is no review article summarizing this imaging modality in the foot and ankle. Therefore, we performed a systematic literature review of relevant clinical studies targeting the use of weightbearing computed tomography in diagnosis of patients with foot and ankle disorders. Furthermore, this review aims to offer insight to those with interest in considering possible future research opportunities with use of this technology. LEVEL OF EVIDENCE: Level V, expert opinion. PMID- 29171284 TI - Hamstring Autograft for Foot and Ankle Applications. AB - BACKGROUND: Hamstring tendon autografts may be used for foot and ankle surgeries, although reports on their effectiveness and morbidity in the foot and ankle literature are limited. We studied a cohort of patients who underwent hamstring harvest for foot and ankle applications, hypothesizing that morbidity to the knee would be limited. METHODS: We studied a cohort of patients who underwent hamstring autograft for foot or ankle applications by a fellowship-trained sports and foot and ankle surgeon since 2011. Thirty-seven patients underwent isokinetic strength testing using a dynamometer an average of 38 months postoperatively. The average patient age was 45 +/- 16 (range, 18-78) years, and 54% were women. Peak flexion and extension torque as well as flexion and extension torque at 30, 70, and 90 degrees of flexion were collected at 2 different testing speeds, 180 and 300 degrees/s. t tests were used for all comparisons. RESULTS: At follow-up, 32 patients (86%) reported no pain at the harvest site; the remaining 5 patients reported mild to moderate symptoms. No patients were dissatisfied, and all would recommend the surgery to someone else. Flexion strength at higher degrees of flexion was significantly lower compared with extension strength as well as compared with flexion strength at lower degrees of flexion, when testing was performed at lower speed ( P < 0.05). CONCLUSIONS: When used for foot and ankle surgery, hamstring autografts resulted in high patient satisfaction with minimal donor site morbidity. While knee flexion strength was decreased at higher degrees of flexion, this finding did not appear to be clinically significant. LEVEL OF EVIDENCE: Level IV, case series. PMID- 29171285 TI - A human right to literacy education: Implications for serving Syrian refugee children. AB - Forty percent of Syrian refugees are younger than 12, and many have not attended school for up to five years, disadvantaging them academically, emotionally, and psychosocially. Article 19 of the Universal Declaration of Human Rights dictates "the right to freedom of opinion and expression...and to seek, receive and impart information and ideas...)". Resettled refugee children face the challenge of integration into majority-English school systems with limited ability to express themselves or linguistic means to access education. However, Syrian adults possess high rates of literacy and funds of knowledge that can promote an environment of learning in the home language. With incomplete language and literacy skills in their native Arabic, learning English for academics proves challenging. Without language and literacy instruction, refugee children experience a lower likelihood of class participation and a greater likelihood of social isolation or drop out. To inform speech-language pathologists and other educators, this literature review aims: (1) to apply second language learning concepts relevant to refugees, (2) to inform pedagogy specific to reading by highlighting cross-linguistic differences between Arabic and English, and (3) to illuminate strategies that families and educators of Arabic-speaking refugee students may employ to resume and promote language and literacy development. PMID- 29171286 TI - The first use of dementia care mapping in the care for older people with intellectual disability: a process analysis according to the RE-AIM framework. AB - INTRODUCTION: The aging of the population with intellectual disability (ID), with associated conseqences as dementia, creates a need for evidence-based methods to support staff. Dementia Care Mapping (DCM) is perceived to be valuable in dementia care and promising in ID-care. The aim of this study was to evaluate the process of the first use of DCM in ID-care. METHODS: DCM was used among older people with ID and care-staff in 12 group homes of six organisations. We obtained data on the first use of DCM in ID-care via focus-group discussions and face-to face interviews with: care-staff (N = 24), managers (N = 10), behavioural specialists (N = 7), DCM-ID mappers (N = 12), and DCM-trainers (N = 2). We used the RE-AIM framework for a thematic process-analysis. RESULTS: All available staff (94%) participated in DCM (reach). Regarding its efficacy, staff considered DCM valuable; it provided them new knowledge and skills. Participants intended to adopt DCM, by continuing and expanding its use in their organisations. DCM was implemented as intended, and strictly monitored and supported by DCM-trainers. As for maintenance, DCM was further tailored to ID-care and a version for individual ID-care settings was developed, both as standards for international use. To sustain the use of DCM in ID-care, a multidisciplinary, interorganisational learning network was established. CONCLUSION: DCM tailored to ID-care proved to be an appropriate and valuable method to support staff in their work with aging clients, and it allows for further implementation. This is a first step to obtain an evidence-based method in ID-care for older clients. PMID- 29171287 TI - When one childhood meets another - maternal childhood trauma and offspring child psychopathology: A systematic review. AB - BACKGROUND: Child maltreatment can have a long-term impact on mental health. Less is known about the consequences of child maltreatment on the next generation's psychological wellbeing. AIM: This systematic review aimed to synthesise the existing empirical literature on the association between a mother's history of maltreatment in her own childhood and her children's experiences of psychopathology, and to characterise potential mediating pathways. METHOD: Electronic database and hand searches yielded 12 studies, with a combined sample size of 45,723 mother-child dyads, which met criteria for inclusion in the review. RESULTS: There was evidence of an overall positive association between a mother's history of child maltreatment and her child's experience of emotional and behavioural difficulties across childhood and adolescence. Maternal psychological distress and poorer parenting practices were found to be key mediating pathways of this association. CONCLUSION: Children of mothers who were exposed to maltreatment in childhood appear to be at an increased risk for psychopathology. Mothers with traumatic childhood experiences should be offered improved access to psychological therapies and parenting programmes to help mitigate the potential impact of child maltreatment on future generations. PMID- 29171289 TI - Preclinical biomarker qualification. AB - Biomarkers are ubiquitously used within drug development programs in both nonclinical species and in humans to assess safety and efficacy of novel compounds. To routinely apply such novel biomarkers with certainty, a well defined data package is necessary for review and endorsement by regulatory agencies including the US Food and Drug Administration, European Medicines Agency, and Japanese Pharmaceuticals and Medical Devices Agency. This type of endorsement is known as regulatory qualification. Novel approaches are being applied to speed the process, lower the resource intensity, and increase the accessibility of biomarker qualification data and it is likely that consortia will continue to play a fundamental role in the qualification process by bringing together like-minded stakeholders focused on specific tools to accelerate drug development. This article will focus on learnings from the previous three nonclinical biomarker qualification projects, as well as discuss the progression of preclinical biomarker projects into the clinical qualification space and the current strategy for the use of nonclinical biomarker data in the translational qualification of clinical biomarkers; much like nonclinical information is used in the approval of drug development candidates. Impact statement This minireview provides an overview of the history of preclinical biomarker qualification by summarizing the three examples of this type of qualification with US Food and Drug Administration, European Medicines Agency, and Japanese Pharmaceuticals and Medical Devices Agency. In addition, an overview of the biomarker qualification process is included to educate key stakeholders with links to relevant white papers that provide information on current evidentiary considerations. The manuscript also provides new information on the evolution of the role that preclinical qualification plays in clinical qualification of biomarkers and the novel approaches that are being utilized to improve the process.

PMID- 29171288 TI - Featured article: Structure moderation of gut microbiota in liraglutide-treated diabetic male rats. AB - The change of gut microbiome is associated with a serious of metabolic disorders, such as diabetes. As a glucagon-like peptide 1 analogue, liraglutide is a potent antidiabetic drug in clinical practice. However, the effect of liraglutide on the community of gut microbiota is still unknown. We aimed to determine the influence of liraglutide on fecal microbiota in diabetic male rats. Five-week-old male Sprague-Dawley rats were fed with a control diet or a high-fat diet for four weeks. By injecting streptozotocin, the diabetic rat model was performed. Diabetic male rats were injected subcutaneously with a low dose of liraglutide (liraglutide 0.2 mg/kg/day), a high dose of liraglutide (liraglutide 0.4 mg/kg/day), or normal saline for 12 weeks. Our data showed that liraglutide effectively prevented the development of diabetes in male rats. Pyrosequencing of the V3-V4 region of 16S rRNA genes manifested a remarkable transfer of gut microbiota construction in liraglutide-treated male rats compared with that of the diabetic male rats. Further analysis identified 879 liraglutide-treated specific operational taxonomic units. Some short-chain fatty acid (SCFA) producing bacteria, including Bacteroides, Lachnospiraceae, and probiotic bacteria, Bifidobacterium, were selectively enhanced in liraglutide-treated diabetic male rats. Lactobacillus was negatively correlated with fasting blood glucose. To sum up, our findings propose that the prevention of diabetes by liraglutide in the diabetic male rats may be associated with the structural change of the gut microbiota, inflammation alleviation, and abundantly elevated SCFA-producing bacteria in the intestine. Impact statement Our findings suggest that significant changes in gut microbiota are associated with liraglutide treatment on the diabetic male rats, including enrichment of short-chain fatty acid producers and probiotic bacteria. This may help alleviate systemic inflammation and contribute to the beneficial effects of liraglutide against diabetes.

AB - The secondary metabolites of Xylaria cf. cubensis SWUF08-86 fungus were investigated, and the chromatographic separation of the crude extracts yielded seventeen compounds. The structure elucidation by spectroscopic analysis including 1D and 2D NMR and the comparison of these data with literature, along with HREIMS spectrometry, revealed one new amino amidine derivative (1), together with five known simple cyclic dipeptide analogs, diketopiperazines (2-6) and eleven other known compounds, including one hemi-cycline (10), three aromatic derivatives (11-13), one sesquiterpene (14) and three sterols (15-17). The isolated compounds were screened for anticancer and anti-pathogenic bacterial and fungal activities. Based on this work, Xylaria cf. cubensis SWUF08-86 has proven to be a diverse secondary metabolites producer. PMID- 29171294 TI - Communication Capacity Research in the Majority World: Supporting the human right to communication specialist services. AB - Receipt of accessible and appropriate specialist services and resources by all people with communication and/or swallowing disability is a human right; however, it is a right rarely achieved in either Minority or Majority World contexts. This paper considers communication specialists' efforts to provide sustainable services for people with communication difficulties living in Majority World countries. The commentary draws on human rights literature, particularly Article 19 of the Universal Declaration of Human Rights and the Communication Capacity Research program that includes: (1) gathering knowledge from policy and literature; (2) gathering knowledge from the community; (3) understanding speech, language and literacy use and proficiency; and (4) developing culturally and linguistically appropriate resources and assessments. To inform the development of resources and assessments that could be used by speech-language pathologists as well as other communication specialists in Fiji, the Communication Capacity Research program involved collection and analysis of data from multiple sources including 144 community members, 75 school students and their families, and 25 teachers. The Communication Capacity Research program may be applicable for achieving the development of evidence-based, culturally and linguistically sustainable SLP services in similar contexts. PMID- 29171295 TI - Rural and remote speech-language pathology service inequities: An Australian human rights dilemma. AB - Access to healthcare is a fundamental human right for all Australians. Article 19 of the Universal Declaration of Human Rights acknowledges the right to freedom of opinion and to seek, receive and impart information and ideas. Capacities for self-expression and effective communication underpin the realisation of these fundamental human rights. For rural and remote Australian children this realisation is compromised by complex disadvantages and inequities that contribute to communication delays, inequity of access to essential speech language pathology services and poorer later life outcomes. Localised solutions to the provision of civically engaged, accessible, acceptable and sustainable speech-language pathology services within rural and remote Australian contexts are required if we are to make substantive human rights gains. However, civically engaged and sustained healthcare can significantly challenge traditional professionalised perspectives on how best to design and implement speech-language pathology services that seek to address rural and remote communication needs and access inequities. A failure to engage these communities in the identification of childhood communication delays and solutions to address these delays, ultimately denies children, families and communities of their human rights for healthcare access, self-expression, self-dignity and meaningful inclusion within Australian society.

The goal is to prevent common problems in care that emerge during the course of dementia by (1) actively engaging the person with dementia in developing a balanced plan of future care with his/her caregiver, (2) increasing use of available services, (3) enhancing dyadic relationship functioning, (4) improving well-being, and (5) evoking satisfaction with components of the intervention. Design and methods Persons with early stage dementia ( n = 128) and their caregivers ( n = 128) were randomly assigned either to Support, Health, Activities, Resources, and Education Program or a control condition. Intervention efficacy was evaluated for completion of a care plan, use of services, dyadic relationship functioning, participant well being, and program satisfaction. Results Dyads in the treatment condition were able to construct a balanced care plan and increased their use of services. Dyadic functioning improved for one dimension (decreased emotional disruptions). Compared to the control condition, satisfaction with the intervention was higher for caregivers enrolled in Support, Health, Activities, Resources, and Education Program on four of five dimensions and one dimension for persons with dementia. IMPLICATIONS: Support, Health, Activities, Resources, and Education Program is a promising prevention approach that takes advantage of the early stage of dementia when both members of the dyad can participate fully in making decisions about later care.

AB - Positive social interaction is important for people with dementia, providing emotional and psychological benefits. Friendships may retain more reciprocal balance than caregiver relationships, which often become one-sided. This qualitative study investigates the meaning that friendship has for people with dementia, and how reciprocity relates to positive social identity. Individuals experiencing dementia were recruited from programs sponsored by a Midwest chapter of The Alzheimer's Association. In a face-to-face, one-time interview, participants were asked to share their perceptions about reciprocal friendship. Participants included 10 individuals who were primarily White, averaged 76 years old, with at least some college education. The data were analyzed using a phenomenological approach that revealed five themes of reciprocal friendship: recognizing the importance of longevity in friendship, helping one another is a normal part of friendship, feeling "alive" through the give and take in friendship, knowing somebody is there for them, and seeking security through friendship.

AB - OBJECTIVE: The purpose of this experimental study was to investigate the role of vitamin supplements (Ocuvite, Vitalux Omega, and Nutrof Total) as possible inhibitors of the onset of age-related macular degeneration (AMD). MATERIALS AND METHODS: The anti-aggregating effect of each vitamin was determined against four accumulative factors namely, platelet activating factor (PAF), adenosine diphosphate (ADP), thrombin receptor-activating peptide (TRAP), and arachidonic acid (AA) in the platelet rich plasma (PRP) of healthy volunteers. RESULTS: Ocuvite, Vitalux Omega, and Nutrof Total were more potent inhibitors against PAF and ADP compared to TRAP and AA. Among the three vitamins, Nutrof Total displayed more potent inhibitions against TRAP and AA, while against PAF and ADP all the three vitamins revealed similar IC50 values. CONCLUSIONS: The vitamins Ocuvite, Vitalux Omega, and Nutrof Total have anti-aggregating effects and therefore can be used against AMD in healthy volunteers. PMID- 29171299 TI - Whole body exposure of rats to sulfur mustard vapor. AB - Sulfur mustard (SM) is an incapacitating chemical warfare agent used in numerous conflicts around the world and it is still a major threat for both, army troops and civilians. To evaluate its multiple targets effects in experimental setup, a model of whole body exposure (WBE) to SM vapor was established in rats and its simultaneous effects on lungs and eyes as well as on general wellbeing were examined. Rats were exposed to SM vapor. Evaluation (up to 10 weeks post exposure) included body weight, general observation, blood counts and histological analysis. Results showed that following a latency-period of several hours, rats typical symptoms developed over a period of more than one week. The initial symptoms, characterized by swollen and erythematic nose, deteriorated into extensive rhinorrhea, eye closure, excessive lacrimation as well as rhonchi, wheezing and breathing difficulties. Alopecia and behavioral abnormality were also recorded. A weight loss of up to 40% was measured within one week with spontaneous recovery to baseline level within three weeks after exposure. Blood counts revealed leukopenia during the first three days post-exposure. Histological evaluation revealed a long lasting damage to the trachea, lungs and eyes. Thus, WBE to SM, was found to closely mimic the deleterious effects of SM on the sensitive tissues previously described in human victims during WWI and the Iran-Iraq war. The use of this animal model will enable comprehensive characterization of changes in biological processes that may lead to the development of therapeutic measures to ameliorate SM induced multi-system injuries.

AB - INTRODUCTION: Maintaining spontaneous ventilation (SV) under total intravenous anesthesia (TIVA) without an endotracheal tube provides uninterrupted and unobstructed surgical access for suspension microlaryngoscopy (SML). This study describes the method and outcome of adults who underwent SML under tubeless TIVA SV. METHODS: Retrospective review of adults who underwent SML between June 2014 and September 2016 using TIVA-SV without an endotracheal tube. RESULTS: Sixty-six cases in 36 patients were included with mean age of 50.6 years and 52.7% were female. Airway pathology included 41.6% subglottic or tracheal stenosis, 19.4% laryngeal lesion or mass, 16.7% glottic stenosis, 13.9% recurrent respiratory papilloma, and 8.3% supraglottic stenosis. Anesthesia was most commonly provided by continuous infusion of propofol and remifentanil (57.6%). Approximately half (53%) of cases received superior laryngeal nerve block. Average operative time was 72.9 minutes (range, 27-166 minutes). Eight cases required supplemental ventilation: 6 cases required transient endotracheal ventilation or mask ventilation, and 2 cases were converted to alternative ventilation. CONCLUSIONS: Total intravenous anesthesia is an attractive alternative to traditional endotracheal tube intubation, jet ventilation, or intermittent apneic ventilation for adult SML. During episodes of hypoventilation or desaturation, endotracheal ventilation, mask ventilation, or jet ventilation can effectively recover oxygenation. PMID- 29171301 TI - Hypolipidemic and cardioprotective effects of Ulva lactuca ethanolic extract in hypercholesterolemic mice. AB - CONTEXT: Hypercholesterolemia has significant cardiac consequences, since it is among the major risk factors of ischemic heart diseases. OBJECTIVE: The aim was searching the cardioprotective effect of chemical constituents from the sea lettuce Ulva lactuca upon hypercholesterolemic regime in mice. MATERIAL AND METHODS: Mice were randomly divided into three groups: untreated group, hypercholesterolemic group, and mice receiving 1% cholesterol associated with U. lactuca ethanolic extract. RESULTS: In vitro study demonstrated that algal extract has antioxidant efficacy attributable to the presence of phenolic compounds. Additionally, the alga alleviated cardiotoxicity, as shown by the improvement of haematological parameters, white cell viability, heart oxidative stress, plasma biochemical parameters and index of atherogenesis. Gene expression of the proinflammatory cytokines TNF-alpha, IL-1beta and IL-6 significantly decreased in the heart of U. lactuca supplemented hypercholesterolemic animals. CONCLUSION: It was established that the green alga, thanks to its bioactive compounds, effectively counteracts cardiotoxic effects of hypercholesterolemic regime.

AB - Many studies have shown that natural marine compounds can prevent biofouling by a broad spectrum of organisms without toxic effects, encouraging their use in antifouling (AF) coatings. Studies over the past 25 years of the natural product zosteric acid (ZA) are systematically organized in this review. ZA is a sulfated phenolic acid produced by the seagrass Zostera marina that has very promising AF potential against several micro- and macrofouling organisms. ZA was shown to have appropriate environmental fate parameters such as high water solubility, a low log P, low bioaccumulation, and no ecotoxicity, which demonstrated the potential of ZA as a safe AF agent. This review also highlights that ZA has been successfully incorporated into several types of coatings. The synthesis of analogs is also considered in this review, and it has allowed a better understanding of ZA structure-AF activity relationships and clarified the mechanism of action of ZA.

AB - OBJECTIVES: Infliximab is effective in patients with ulcerative colitis (UC); however, one-third of patients do not respond and require additional therapies such as other biologic agents. Therefore, the aim of this study was to analyze the association between pro-inflammatory molecules and clinical efficacy to elucidate possible mechanisms for the non-response to infliximab to aid in treatment selection. MATERIALS AND METHOD: Patients with moderate-to-severe active UC receiving infliximab in our hospital between 2010 and 2016 for whom pre treatment serum samples were available were retrospectively evaluated. We analyzed the association between serum interleukin (IL)-6, tumor necrosis factor alpha (TNF-alpha) and soluble mucosal vascular addressin cell adhesion molecule-1 (sMAdCAM-1) and the clinical efficacy of infliximab. The primary endpoint was clinical response at the end of the induction period. RESULTS: Forty-one patients were included in this study. After induction therapy, 27 patients (65.9%) showed a clinical response. Serum IL-6 levels were significantly lower in responders than in non-responders (p = .012), whereas no significant differences were noted in other factors including sMAdCAM-1 and TNF-alpha. Multivariate analysis identified that serum IL-6 level (odds ratio = 0.72; 95% confidence interval, 0.54-0.96; p = .027) was independently associated with response to infliximab. CONCLUSIONS: Serum IL-6 level is associated with response to infliximab in UC. Elevated concentrations of IL-6 may provide insight to the mechanism of non response to infliximab. PMID- 29171307 TI - Pre-injury job characteristics and return to work among injured workers in South Korea: differences by socio-demographic and injury-related characteristics. AB - PURPOSE: This study examined the effect of pre-injury job characteristics on the odds of RTW outcomes for specific socio-demographic and injury-related characteristics among injured workers in South Korea. METHODS: This study employed first-wave data for 1993 participants from the Panel Study of Workers' Compensation Insurance. A two-step cluster analysis was conducted to profile pre injury job characteristics, including monthly wages, length of service, company size, contract type, and working hours. For each subsample selected by the characteristics of the independent variables, multinomial logistic regression analyses were performed to predict the odds ratio for being unemployed or working in a new firm versus returning to the pre-injury job, depending on cluster membership. RESULTS: Two clusters were identified with pre-injury job characteristics. Workers in the unstable employment cluster were more likely than were workers in the stable employment cluster to be unemployed or work in a new firm rather than return to the pre-injury job; this held for all socio demographic and injury-related characteristics. CONCLUSIONS: Our results showed a need to develop differential RTW strategies for injured workers in insecure jobs at the time of injury. Implications for rehabilitation Policymakers and rehabilitation practitioners need to take into account not only socio-demographic or injury-related characteristics but also working conditions at the time of injury when designing return-to-work programs for injured workers in South Korea. Injured employees in poor working conditions are relatively more vulnerable in the return-to-work process and deserve special attention and supports from the Korean government. The Korean government needs to review return-to-work policies for injured workers in unstable employment environment in the context of employment relationships rather than individual characteristics. PMID- 29171308 TI - Family-directed approach to brain injury (FAB) model: a preliminary framework to guide family-directed intervention for individuals with brain injury. AB - PURPOSE: This article proposes a theoretical framework to help professionals include family as active members in brain injury rehabilitation. A trend towards greater family involvement has lead to the development of family-collaboration models. However, current models appear to focus on information sharing rather than increasing the capability of family members. This article introduces a family-directed approach to brain injury model, which provides a theoretical framework for supporting family as facilitators of change. METHODS: Family collaboration models and literature regarding family experiences following brain injury and support needs are reviewed to identify the driving forces behind family engagement in rehabilitation, including effective professional-family relationships, and important factors in the delivery of education underpinned by evidence-based practices. RESULTS: The family-directed approach to brain injury model is based on principles of hope, family expertise, education/skill building, and family-directed intervention. CONCLUSIONS: The family-directed approach to brain injury model provides a theoretical framework for educating and training family members as facilitators in the management process: promoting competence rather than dependency on service systems. Guiding recommendations encourage professionals to reflect on the importance of their therapeutic relationships and their capacity to positively impact rehabilitation outcomes beyond the technical aspects of health care and treatment. Implications for Rehabilitation Training family members as facilitators in the rehabilitation process is suggested to reduce dependency on the service system, address families' unmet support needs, and to optimize rehabilitation outcomes for individuals with brain injury. The family-directed approach to brain injury model is proposed to guide the increased involvement of family as active members in the rehabilitation team and to define potential active ingredients in this process. PMID- 29171310 TI - The impact of speech and language problems in kindergarten on academic learning and special education status in grade three. AB - PURPOSE: This study addressed the implications of experiencing early speech language pathologies (SLPs) in kindergarten on special education needs (SEN) and academic outcomes in grade three. METHOD: Early Development Instrument (EDI) kindergarten data on development and the presence or absence of SLPs were matched with grade three school-system standardised tests of reading, writing and maths, and SEN classification in Ontario, Canada for 59 015 students. Children were classified as having a Persistent speech language pathology (SLP), Remittent SLP, Latent SEN or as a typically developing Control. RESULT: Even though 72.3% of children's SLPs remitted by grade three, kindergarten SLPs conveyed higher likelihood of having an SEN, and of lower achievement levels in grade three. The degree of impact varied between Persistent and Remittent groups. Children in the Latent group had lower scores in kindergarten on all five EDI domains than Control children. CONCLUSION: These population level results provide strong evidence to indicate that all children who present with an SLP in kindergarten face further academic challenges, even if their SLP resolves over time. Findings have implications for early intervention and treatment for children with early SLPs.

AB - Lichen striatus is an acquired, benign, linear inflammatory dermatosis characterized by a sudden skin eruption along Blaschko's lines that usually is not associated with specific etiologic agents. In most cases, it is a self limited dermatosis, but may relapse. Topical steroids are its first-line therapy, but this treatment is not always effective. We describe the case of a 45-year-old woman affected by a lichen striatus on her right limb resistant to topical corticosteroid therapy. The patient was successfully treated with cyclosporine (4 mg/kg/die) for 4 weeks with no recurrence of the dermatitis during the subsequent 1-year follow-up period. PMID- 29171312 TI - Acute lateral ankle sprain to chronic ankle instability: a pathway of dysfunction. AB - Lateral ankle sprains (LAS) have been reported as one of the most common musculoskeletal injuries observed in sports and in individuals who are recreationally active. Approximately 40% of individuals who sustain a LAS develop a condition known as chronic ankle instability (CAI). Years of research has identified numerous impairments associated with CAI such as decreases in range of motion (ROM), strength, postural control, and altered movement patterns during functional activities when compared to individuals with no LAS history. As a result, an impairment-based rehabilitation model was developed to treat the common impairments associated with CAI. The impairment-based rehabilitation model has been shown to be an effective rehabilitation strategy at improving both clinical and patient-oriented outcomes in patients with CAI. To date, the efficacy of an impairment-based rehabilitation model has not been evaluated in patients with an acute LAS. Prior to implementing an impairment-based model for the treatment of an acute LAS, similarities between impairments associated with acute LAS and CAI across the spectrum of the healing process is warranted. Therefore, the purpose of this review paper is to compare and contrast impairments and treatment techniques in individuals with an acute LAS, sub-acute LAS, and CAI. A secondary purpose of this review is to provide clinical commentary on the management of acute LAS and speculate how the implementation of an impairment-based rehabilitation strategy for the treatment of acute LAS could minimize the development of CAI. The main findings of this review were that similar impairments (decreased ROM, strength, postural control, and functional activities) are observed in patients with acute LAS, sub-acute LAS, and CAI, suggesting that the impairments associated with CAI are a continuation from the original impairments developed during the initial LAS. Therefore, the use of an impairment-based model may be advantageous when treating patients with an acute LAS.

PMID- 29171314 TI - Quality of life in Indian women with fertility problems as assessed by the FertiQoL questionnaire: a single center cross sectional study. AB - PURPOSE: Infertility and its treatment can significantly impact an individual's physical and psychological health; however, this has not been well-studied in the Indian population. This study aimed to assess the quality of life in women with infertility at a teaching hospital in Hyderabad, India. METHODS: In this cross sectional study of women with infertility, the quality of life was measured using the 'FertiQoL International' questionnaire (English/Hindi). RESULTS: The age ranged from 20 to 38 years and polycystic ovary syndrome was the most common cause of infertility. Core FertiQoL scores were analyzed in 215 women and Treatment FertiQoL in 156. The mean Total FertiQoL score in the study population was 66.1 (SD 13.0) and this overall score was not influenced by socio-demographic or infertility-specific factors. However, on subscale analysis, women who had living children and were university-educated had significantly better emotional scores while obese (>=35 kg/m2) women and those on ovulation induction treatment had poorer mind body and relational scores, respectively. Women with associated co-morbidities had worse quality of life on the Treatment Environment scale than those without. CONCLUSIONS: The results provide a baseline quality of life score in these women. Infertility had the greatest impact on the emotional domain. PMID- 29171315 TI - Suppressive effect of Okara on intestinal lipid digestion and absorption in mice ingesting high-fat diet. AB - Soymilk residue Okara is paid attention as a low-calorie foodstuff effective for the amelioration of obesity, and expected to have the potential ability to reduce calorie intake by suppressing the digestion and absorption of high-calorie nutrients in the intestinal tract. Then, the direct effect of Okara extract on lipase activity was examined, and this extract was shown to inhibit the enzyme activity. On the other hand, the spray-dried powder of Okara extract was suspended in a drinking water and given to mice fed with a high-fat diet. Consequently, Okara suspension was shown to reduce triglyceride (TG) levels in the blood, thus suggesting that Okara ingestion could suppress the digestion and absorption of lipids through the inhibition of lipase activity in the intestinal tract. Therefore, Okara is speculated to have the potential ability to prevent the excess intake of calories, thereby being effective and useful for the amelioration of metabolic syndrome. PMID- 29171316 TI - HBB: c.316-125A>G and HBB: c.316-42delC: Phenotypic Evaluations of Two Rare Changes in the Second Intron of the HBB Gene. AB - We report two very rare changes in the second intron of the HBB gene, a substitution at nucleotide (nt) 726 [IVS-II-726 (A>G) (beta+), NM_000518, HBB: c.316-125A>G] and a deletion of a cytosine at nt 809 [IVS-II-809 (-C) (beta), NM_000518, HBB: c.316-42delC] identified during the screening program for hemoglobinopathies in the resident Sicilian population. The purpose of this study was to evaluate the clinical implication of these rare changes, particularly in coinheritance with known mutations in the globin clusters, in order to conduct an appropriate genetic counseling for at-risk couples. Molecular analysis detected the first rare nt substitution in two cases in simple heterozygosity and in two cases in association with other known mutations on globin genes, while the deletion was identified in a pregnant woman, carrier of beta-thal, and in her fetus at prenatal diagnosis (PND) for hemoglobinopathies. The present study emphasizes the importance of sharing the observed changes in the globin gene cluster, especially in the case of new or rare undefined mutations, in order to facilitate the determination of their phenotypic expression and possible interactions with known molecular defects.

AB - OBJECTIVE: In literature, recent evidence has shown that the hypothalamic pituitary-adrenal (HPA) axis can be dysregulated in patients with post-traumatic stress disorder (PTSD) and HPA axis hormones may predict the psychotherapy treatment response in patients with PTSD. In this study, it was aimed to investigate changing cortisol and DHEA-S levels post-eye movement desensitization and reprocessing (EMDR) therapy and the relationship between treatment response and basal cortisol, and DHEA-S levels before treatment. METHOD: The study group comprised 40 adolescents (age, 12-18 years) with PTSD. The PTSD symptoms were assessed using the Child Depression Inventory (CDI) and Child Post-traumatic Stress Reaction Index (CPSRI) and the blood cortisol and DHEA-S were measured with the chemiluminescence method before and after treatment. A maximum of six sessions of EMDR therapy were conducted by an EMDR level-1 trained child psychiatry resident. Treatment response was measured by the pre- to post treatment decrease in self-reported and clinical PTSD severity. RESULTS: Pre- and post-treatment DHEA-S and cortisol levels did not show any statistically significant difference. Pre-treatment CDI scores were negatively correlated with pre-treatment DHEA-S levels (r: -0.39). ROC analysis demonstrated that the DHEA S/cortisol ratio predicts treatment response at a medium level (AUC: 0.703, p: .030, sensitivity: 0.65, specificity: 0.86). CONCLUSION: The results of this study suggested that the DHEA-S/cortisol ratio may predict treatment response in adolescents with PTSD receiving EMDR therapy. The biochemical parameter of HPA axis activity appears to be an important predictor of positive clinical response in adolescent PTSD patients, and could be used in clinical practice to predict PTSD treatment in the future. PMID- 29171319 TI - Cost-effectiveness of TYRX absorbable antibacterial envelope for prevention of cardiovascular implantable electronic device infection. AB - AIMS: Infection is a major complication of cardiovascular implantable electronic device (CIED) therapy that usually requires device extraction and is associated with increased morbidity and mortality. The TYRX Antibacterial Envelope is a polypropylene mesh that stabilizes the CIED and elutes minocycline and rifampin to reduce the risk of post-operative infection. METHODS: A decision tree was developed to assess the cost-effectiveness of TYRX vs standard of care (SOC) following implantation of four CIED device types. The model was parameterized for a UK National Health Service perspective. Probabilities were derived from the literature. Resource use included drug acquisition and administration, hospitalization, adverse events, device extraction, and replacement. Incremental cost-effectiveness ratios (ICERs) were calculated from costs and quality-adjusted life-years (QALYs). RESULTS: Over a 12-month time horizon, TYRX was less costly and more effective than SOC when utilized in patients with an ICD or CRT-D. TYRX was associated with ICERs of L46,548 and L21,768 per QALY gained in patients with an IPG or CRT-P, respectively. TYRX was cost-effective at a L30,000 threshold at baseline probabilities of infection exceeding 1.65% (CRT-D), 1.95% (CRT-P), 1.87% (IPG), and 1.38% (ICD). LIMITATIONS AND CONCLUSIONS: Device-specific infection rates for high-risk patients were not available in the literature and not used in this analysis, potentially under-estimating the impact of TYRX in certain devices. Nevertheless, TYRX is associated with a reduction in post-operative infection risk relative to SOC, resulting in reduced healthcare resource utilization at an initial cost. The ICERs are below the accepted willingness-to pay thresholds used by UK decision-makers. TYRX, therefore, represents a cost effective prevention option for CIED patients at high-risk of post-operative infection. PMID- 29171320 TI - The role of mitochondrial folate enzyme MTHFD1L in esophageal squamous cell carcinoma. AB - OBJECTIVE: The lack of novel therapeutic targets poses the major challenge to prolong survival and improve the quality of life for esophageal squamous cell carcinoma (ESCC). Methylenetetrahydrofolate dehydrogenase 1-like (MTHFD1L) plays critical roles in folate cycle maintenance. However, little information is available concerning the role of MTHFD1L in cancer cells, and no studies have addressed such issues in esophageal cancer. MATERIALS AND METHOD: Surgical cancer and adjacent normal esophageal tissues were obtained from patients with esophagectomy and esophagogastrostomy for ESCC. Western blot, immunohistochemistry and Quantitative RT-PCR were performed to evaluate protein and RNA expression levels of MTHFD1L. Knockdown of MTHFD1L expression was achieved by using short hairpin RNA. The effects of MTHFD1L silencing on ESCC cell proliferation and apoptosis were assessed by the MTT assay, Celigo assays, Annexin V FACS assay and Caspase-3/7 array in vitro. RESULTS: Twenty-three paired cancer and adjacent normal esophageal tissues from patients with ESCC were included in this study. MTHFD1L protein and RNA expression levels were significantly upregulated in ESCC tissue as compared with normal tissue. High expression of MTHFD1 was also detected in two esophageal cancer cell lines (TE-1 and EC109). Knockdown of MTHFD1L expression inhibited the proliferation of TE-1 cells, and the apoptosis was distinctly increased following shMTHFD1L infection. CONCLUSIONS: Our preliminary study highlighted for the first time that MTHFD1L might be involved in the development of ESCC, which may provide a new potential tumor-specific therapeutic targeting for anti-folate agents. PMID- 29171321 TI - Changes in medical student implicit attitudes following a health equity curricular intervention. AB - PURPOSE: This study assessed the: (1) effect of an LGBTQI + health equity curriculum (eQuality) on implicit attitudes among first (M1) and second year (M2) medical students and (2) utility of dedicated time to explore implicit bias. METHOD: Implicit biases were assessed at baseline using implicit association tests (IAT) for all M2s and a random sample of first years (M1A). These students were then debriefed on strategies to mitigate bias. Following eQuality, all M1 and M2s completed post-intervention IATs. The remaining first years (M1B) were then debriefed. Paired sample t-tests assessed differences between pre/post. Independent sample t-tests assessed differences in post-IATs between M1 groups. RESULTS: IATs indicated preferences for "Straight," "White," and "Thin" at both pre and post. M2s demonstrated statistically significant improvements pre to post for sexuality (p = 0.01) and race (p = 0.03). There were significant differences in post-intervention IAT scores between M1As who received the IAT and debriefing prior to eQuality and M1Bs for sexuality (p = 0.002) and race (p = 0.046). There were no significant changes for weight. CONCLUSION: eQuality reduced implicit preference for "Straight" and "White." Differences in M1 post-intervention IAT scores between groups suggest dedicating time to debrief implicit attitudes enhances bias mitigation. PMID- 29171322 TI - Graft fixation influences revision risk after ACL reconstruction with hamstring tendon autografts. AB - Background and purpose - A large number of fixation methods of hamstring tendon autograft (HT) are available for anterior cruciate ligament reconstruction (ACLR). Some studies report an association between fixation method and the risk of revision ACLR. We compared the risk of revision of various femoral and tibial fixation methods used for HT in Scandinavia 2004-2011. Materials and methods - A register-based study of 38,666 patients undergoing primary ACLRs with HT, with 1,042 revision ACLRs. The overall median follow-up time was 2.8 (0-8) years. Fixation devices used in a small number of patients were grouped according to design and the point of fixation. Results - The most common fixation methods were Endobutton (36%) and Rigidfix (31%) in the femur; and interference screw (48%) and Intrafix (34%) in the tibia. In a multivariable Cox regression model, the transfemoral fixations Rigidfix and Transfix had a lower risk of revision (HR 0.7 [95% CI 0.6-0.8] and 0.7 [CI 0.6-0.9] respectively) compared with Endobutton. In the tibia the retro interference screw had a higher risk of revision (HR 1.9 [CI 1.3-2.9]) compared with an interference screw. Interpretation - The choice of graft fixation influences the risk of revision after primary ACLR with hamstring tendon autograft. PMID- 29171324 TI - Obstructive and restrictive pulmonary dysfunction in long-term lymphoma survivors after high-dose therapy with autologous stem cell transplantation. AB - BACKGROUND: Obstructive and restrictive dysfunction in long-term lymphoma survivors (LSs) after high-dose therapy with autologous stem-cell transplantation (HDT-ASCT) has not been addressed systematically previously. MATERIAL AND METHODS: LSs treated in Norway 1987-2008 with HDT-ASCT who performed spirometry, measurement of static lung volumes and echocardiography 2012-2014 at either Oslo or St. Olavs University Hospitals was eligible. Smoking data were recorded by questionnaire. Treatment data were collected from medical records or hospital databases. Factors associated with obstructive and restrictive impairments (dichotomous outcomes) were examined by Poisson regression. Linear regression with the margins post-estimation command was used to derive adjusted mean values of forced expiratory volume in 1 s (FEV1). We used the normative reference data recommended by the European Respiratory Society for calculating percent predicted values. RESULTS: A total of 226 LSs were studied, of whom 11.5 and 5.8% had obstructive and restrictive impairment, respectively. For women and men, mean FEV1 was 2.31 and 3.34 l corresponding to 11.4%- and 11.1%-points below that predicted from norms, respectively. In multivariable regression analyses, cumulative doxorubicin dose (400-775 mg/m2) and current smoking were associated with increased risk of obstructive impairment, and chest RT (>13-66 Gy) was associated with increased risk of restrictive impairment. Currently smoking LSs within the highest doxorubicin category (400-775 mg/m2), had the lowest adjusted mean FEV1. CONCLUSIONS: Despite intensive cancer treatment, our analysis showed modest reductions in obstructive parameters among long-term LSs after HDT-ASCT compared to normative reference data. To limit obstructive impairments in LSs after HDT-ASCT, we suggest that targeted smoking-cessation advice is directed towards patients who have received high cumulative doses of doxorubicin.

AB - CONTEXT: Limonoids possess broad range of biological activities, including antitumour, antimicrobial and antioxidant activities, etc. Eudesmin (EDN) is a type of limonoid which also possesses various activities. However, there is no report on the antitumour lung cancer (LC) activities of this compound. OBJECTIVE: The present study investigates the antitumour effects of EDN and its potential molecular mechanisms. MATERIALS AND METHODS: The in vitro antitumour effects of EDN on LC A549 cells were evaluated by using MTT assay. The in vivo antitumour effects were investigated on a xenograft athymic nude mouse model. The mice were administered orally with EDN (10, 20 and 40 mg/kg) once daily for 28 days. Effects of EDN on apoptosis-related or signalling proteins (Bcl-2, Bax, caspase 3, caspase-9, P53, Akt and JNK) were assayed by western blot analysis. RESULTS: EDN showed significant inhibitory effects on the growth of LC A549 cells in vitro with the half maximal inhibitory concentration (IC50) of 18.3 MUM. By treating with EDN (10, 20 and 40 MUM), expression of caspase-3, caspase-9, Bax, P53 and phosphorylated JNK in A549 cells were significantly upregulated, whereas expression of Bcl-2 and Akt phosphorylation were significantly down-regulated. Interestingly, EDN-induced apoptosis could be attenuated by JNK inhibitor. In addition, in vivo experiments also indicated EDN (10, 20 and 40 mg/kg) had significant antitumour effects (p < 0.01) on nude mice. CONCLUSIONS: Overall, the results indicated that EDN possesses significant antitumour effects on LC and the possible mechanism might be related to induction of mitochondria-mediated apoptosis.

AB - This review critically examines the data on claimed endocrine-mediated adverse effects of chemicals on wildlife populations. It focuses on the effects of current-use chemicals, and compares their apparent scale and severity with those of legacy chemicals which have been withdrawn from sale or use, although they may still be present in the environment. The review concludes that the effects on wildlife of many legacy chemicals with endocrine activity are generally greater than those caused by current-use chemicals, with the exception of ethinylestradiol and other estrogens found in sewage effluents, which are causing widespread effects on fish populations. It is considered that current chemical testing regimes and risk assessment procedures, at least those to which pesticides and biocides are subjected, are in part responsible for this improvement. This is noteworthy as most ecotoxicological testing for regulatory purposes is currently focused on characterizing apical adverse effect endpoints rather than identifying the mechanism(s) responsible for any observed effects. Furthermore, a suite of internationally standardized ecotoxicity tests sensitive for potential endocrine-mediated effects is now in place, or under development, which should ensure further characterization of substances with these properties so that they can be adequately regulated.

AB - BACKGROUND: "Student-as-Teacher" (SaT) programs have been growing in number to prepare medical students for their teaching roles in residency and beyond, but it remains unknown what content areas should be covered in SaT curricula. AIM: To determine five to ten "essential" content areas for inclusion in SaT curricula using expert opinion. METHODS: Using a three-round Delphi process, moderators iteratively surveyed a panel of 28 medical educators (25 academy directors and three individuals identified as having expertise in undergraduate medical education) representing 25 medical schools in the United States. This "SaT Delphi Working Group" was tasked with rating topics for inclusion in SaT curricula on a 3-point scale (i.e. 1. "essential," 2. "important, but not essential" 3. "not important"). Topics achieving >=70% consensus as "essential," "important" or "not important" were accepted by the moderators and removed from subsequent rounds. RESULTS: Hundred per cent response rate (n = 28) was achieved for all survey rounds. Five content areas reached consensus as "essential" for inclusion in a SaT curriculum: feedback, bedside teaching and clinical precepting, small-group teaching, case-based teaching and professionalism as a medical educator. CONCLUSION: This consensus from a group of leaders in medical education is a first step toward the implementation of more developmentally-appropriate SaT competencies.

PMID- 29171328 TI - Emerging roles of DROSHA beyond primary microRNA processing. AB - DROSHA is the catalytic subunit of the Microprocessor complex, which initiates microRNA (miRNA) maturation in the nucleus by recognizing and cleaving hairpin precursors embedded in primary transcripts. However, accumulating evidence suggests that not all hairpin substrates of DROSHA are associated with the generation of functional small RNAs. By targeting those hairpins, DROSHA regulates diverse aspects of RNA metabolism across the transcriptome, serves as a line of defense against the expression of potentially deleterious elements, and permits cell fate determination and differentiation. DROSHA is also versatile in the way that it executes these noncanonical functions, occasionally depending on its RNA-binding activity rather than its catalytic activity. Herein, we discuss the functional and mechanistic diversity of DROSHA beyond the miRNA biogenesis pathway in light of recent findings. PMID- 29171331 TI - The Y-V plasty for first web space release.

AB - Service learning is an educational methodology that facilitates transformation of students' knowledge, attitudes and attitudes around holistic care through work with community organizations. To implement academically, defensible service learning requires faculty endorsement, consideration of course credit, an enthusiastic champion able to negotiate agreements with organizations, organizations' identification of their own projects so they are willing to both fund and supervise them, curricular underpinning that imparts the project skills necessary for success, embedding at a time when students' clinical identity is being formed, small packets of curriculum elements delivered "just in time" as students engage with their project, flexible online platform/s, assessment that is organically related to the project, providing cross cultural up-skilling, and focused on the students' responsibility for their own product. The result is a learning experience that is engaging for medical students, links the university to the community, and encourages altruism which is otherwise reported to decline through medical school. PMID- 29171335 TI - The cardiovascular benefits of indiscriminate supplementation of omega-3 fatty acids; meta-analysis and decision-making approach. AB - AIM: The meta-analysis was conducted to estimate of the cardiovascular benefits of indiscriminate supplementation of omega-3 capsules. The results, expressed in terms of quality adjusted life years (QALY) intuitively understood by the general public, can be the basis for the (personal) decision on whether to take omega-3 supplements. METHODS: The results of meta-analysis of eight double-blind, placebo controlled clinical trials are expressed in terms of QALY, using the Markov model and Monte Carlo simulations. RESULTS: Omega-3 supplementation results in a 8% decrease of the risk of cardiac death, unless the patients are treated by statins. Results indicate that omega-3 supplementation may prolong QALY by about a month. Old people gain less, whereas DM-2 patients and people with history of CV events gain more. DISCUSSION: Our analysis yielded an algorithm for estimating benefit from omega-3 supplementation, based on the age and the individual risk of CV events of the patient. PMID- 29171334 TI - G-Quadruplexes influence pri-microRNA processing. AB - RNA G-Quadruplexes (G4) have been shown to possess many biological functions, including the regulation of microRNA (miRNA) biogenesis and function. However, their impact on pri-miRNA processing remains unknown. We identified G4 located near the Drosha cleavage site in three distinct pri-miRNAs: pri-mir200c, pri mir451a, and pri-mir497. The folding of the potential G4 motifs was determined in solution. Subsequently, mutations disrupting G4 folding led to important changes in the mature miRNAs levels in cells. Moreover, using small antisense oligonucleotides binding to the pri-miRNA, it was possible to modulate, either positively or negatively, the mature miRNA levels. Together, these data demonstrate that G4 motifs could contribute to the regulation of pri-mRNA processing, a novel role for G4. Considering that bio-informatics screening indicates that between 9% and 50% of all pri-miRNAs contain a putative G4, these structures possess interesting potential as future therapeutic targets.

AB - We compared the timed performance and compensatory movements of 32 boys (mean age = 10.0 years) with Duchenne muscular dystrophy (DMD) and 38 healthy boys (mean age = 9.2 years) on 10 -meter walking and four-step stair work (climbing and descending). Dependent measures were digital scores on the Functional Evaluation Scale for DMD obtained by watching the boys on film. Groups were compared initially and after 6 and 12 months, using General Linear Models analysis (for two groups and three assessments). Results showed no significant timed performance differences between groups on 10 -m walking at the initial assessment; but boys with DMD showed longer times after 6 and 12 months, and boys with DMD engaged in more compensatory movements while walking. For stair climbing, boys with DMD were significantly slower than healthy controls when both climbing and descending steps in all assessments. PMID- 29171338 TI - Effects of a Dual Swallow-Attention Task on Swallow and Cognitive Performance Measures. AB - Research evidence has mounted that cognitive distracters can be detrimental to concurrent motor performance. Yet, few investigations have probed how cognitive distracters might impact dysphagia (swallowing impairment) though secondary tasks, like watching television, now compete with swallowing in a 21st-century lifestyle. Accordingly, we sought to determine whether cognitive distracters while swallowing alter swallowing or cognitive performance among healthy young adults. Participants were 30 healthy volunteers 18-24 years of age who underwent a baseline swallow task (BST), a baseline cognitive task (BCT), and a dual task (DT) in randomized order. The BST consisted of consuming 100 mL of (a) luke warm water (LWW) and (b) carbonated sweet water (CSW). The BCT involved pressing a key to indicate speed or reaction time for completing a number recognition task. In the DT condition, swallow and cognitive tasks were performed concurrently. Volume/swallow (V/S), time/swallow (T/S), and swallow capacity (SC) indices were derived for the swallow task and reaction time in milliseconds reflected cognitive task performance. On comparison between baseline and the DT condition, there was a decrease in V/S, increase in T/S, and an overall reduction in SC across LWW and CSW. Moreover, there was a slower cognitive reaction time in the DT condition. A significant repeated measures of ANOVA difference was noted between baseline and DT conditions ( p < .001). We conclude that swallowing should not be done in the presence of cognitively distracters.

AB - Establishing fidelity processes and measures is an important step in the development of interventions. Accurate referencing, naming of interventions and robust discussion of deviations from the theories, methods or terminology underpinning interventions support the fidelity of future applications of interventions in research and clinical settings. This commentary clarifies the establishment of fidelity for Occupational Performance Coaching (OPC) in relation to a recent article on this topic by Dunn and colleagues. Fundamental flaws in the referencing, labelling, theoretical underpinnings and methods inaccurately described as OPC are outlined. Guidance in establishing fidelity for future applications of OPC is provided. PMID- 29171340 TI - Measurement properties and feasibility of the Loughborough soccer passing test: A systematic review. AB - The purpose of this paper was to systematically review the literature and examine the research methodological quality, measurement properties and feasibility of the Loughborough Soccer Passing Test (LSPT). Databases were searched up to June 2017. Twenty five studies fulfilled the eligibility criteria. The main methodological limitations of the studies were the small sample size and the lack of information on participants and eligibility criteria. Results showed that test retest reliability of the LSPT was moderate to excellent. Good discriminative validity was found between playing levels and ages. The LSPT was positively correlated with sprint, dribbling, and agility test; however, a weak correlation was established with in-game performance. Test responsiveness (an ability to detect change over time) to some external interventions was observed in studies. Adjusted Cronbach's alpha (alpha = 0.67), smallest worthwhile change (SWC = 0.8 3.8) and minimal detectable change (MDC50 = 1.9-11.3) were calculated based on available data. The findings indicate that the LSPT has acceptable test-retest reliability and discriminative validity. However, it may not be a feasible and effective way to interpret the intra-individual change of skill performance in practice. Future work should be undertaken to establish additional measurement properties of the LSPT, and to improve its practical feasibility. PMID- 29171341 TI - Diagnosis of a tympanic paraganglioma with CT perfusion imaging: a technical note and case description. AB - Paragangliomas can be diagnosed accurately using magnetic resonance imaging and dynamic four-dimensional magnetic resonance angiography. Four-dimensional imaging uses the highly vascularised structure of these tumours, which results in a homogenous capillary blush and usually, due to the arteriovenous shunting, in an early draining vein. By these features the tumour can be differentiated from other neoplasms. The authors describe a case of a paraganglioma localised in the middle ear of an elderly patient. Magnetic resonance contraindications led to preoperative diagnostics with high resolution computed tomography of the temporal bone and additionally computed tomography perfusion imaging instead of magnetic resonance imaging with four-dimensional magnetic resonance angiography. Using the computed tomography perfusion dataset, regions of interest were placed in the carotid artery, the sigmoid sinus and the tympanic mass. In the computer-assisted analysis the tumour showed late arterial enhancement and delayed wash-out compared to the enhancement curves of the carotid artery and the sigmoid sinus. This corresponded to the highly vascularised nature of a paraganglioma. On postoperative follow-up imaging computed tomography perfusion showed almost no enhancement of a small residual tympanic mass, which was then considered to be granulation tissue. In conclusion, in the case of magnetic resonance contraindications the preoperative diagnosis of tympanic paraganglioma can be made using computed tomography imaging criteria alone. Computed tomography perfusion imaging may be helpful in these cases to detect residual or recurrent tumour.

AB - The title family of mixed-ligand oxidovanadium(V) hydrazone complexes are [VVO(HL1)(hq)] (1) and [VVO(HL2)(hq)] (2), where (HL1)2- and (HL2)2- are the dinegative form of 2-hydroxybenzoylhydrazone of acetylacetone (H3L1) and benzoylacetone (H3L2), respectively, and hq- is the mononegative form of 8 hydroxyquinoline (Hhq). Complexes were used to determine their binding constant with CT DNA using various spectroscopic techniques namely, electronic absorption, fluorescence and circular dichroism spectroscopy. The binding constant values suggest the intercalative mode of binding with the CT DNA and follow the order: 2 > 1. The bulky size as well as electron withdrawing property of the phenyl group (which is present in the beta-diketone part of the hydrazone moiety in complex 2 in place of a CH3 group in complex 1) is responsible for the higher activity of 2 than 1. Complexes were screened for cytotoxic activity on cervical cancer cells and were found to be potentially active (IC50 value for 1 and 2 is 33 and 29 MUM, respectively), even better than the widely used cis-platin (IC50 = 63.5 MUM) and carboplatin (IC50 = > 200 MUM) which is evident from the respective IC50 value. Nuclear staining experiment suggests that these complexes kill the SiHa cancer cells through apoptotic mode. The molecular docking study also suggested the intercalative mode of binding of these complexes with CT DNA and HPV 18 DNA.

AB - Acute exercise reduces postprandial triacylglycerol concentrations ([TAG]) in boys and girls; however, it is not known whether between-sex differences exist in response to exercise. Fifteen boys (mean(SD): 11.8(0.4) years) and sixteen girls (12.1(0.7) years) completed two, 2-day conditions. On day 1, participants rested (CON) or completed 10 * 1 min high-intensity interval runs at 100% maximal aerobic speed with 1 min recovery (HIIR). On day 2, participants consumed a standardised breakfast and lunch over a 6.5-h period during which seven capillary blood samples were collected. Based on ratios of the geometric means (95% CI for ratios), fasting [TAG] was 32% lower in boys than girls (-44 to -18%, ES = 1.31, P < 0.001), and 12% lower after HIIR than CON (-18 to -5%, ES = 0.42, P = 0.003); the magnitude of reduction was not significantly different between the sexes (8% (ES = 0.36) vs. 15% (ES = 0.47), respectively; P = 0.29). The total area under the [TAG] versus time curve was 27% lower in boys than girls (-40 to -10%, ES = 1.02, P = 0.005), and 10% lower after HIIR than CON (-16 to -5%, ES = 0.36, P = 0.001); the magnitude of reduction was similar between the sexes (11% (ES = 0.43) vs. 10% (ES = 0.31), respectively; P = 0.87). The small-moderate reduction in postprandial [TAG] after HIIR was similar between the sexes.

AB - Ikshusterol3-O-glucoside was isolated from Clematis gouriana Roxb. ex DC. root. A structure of the isolated compound was determined on the basis of various spectroscopic interpretations (UV, NMR, FTIR, and GC-MS-EI). This structure was submitted in the PubChem compound database (SID 249494133). SID 249494133 was carried out by density functional theory calculation to observe the chemical stability and electrostatic potential of this compound. The absorption, distribution, metabolism, and excretion property of this compound was predicted to evaluate the drug likeness and toxicity. In addition, molecular docking, quantum polarized ligand docking, prime MMGBSA calculation, and induced fit docking were performed to predict the binding status of SID 249494133 with the active site of phospholipase A2 (PLA2) (PDB ID: 1A3D). The stability of the compound in the active site of PLA2 was carried out using molecular dynamics simulation. Further, the anti-venom activity of the compound was assessed using the PLA2 assay against Naja naja (Indian cobra) crude venom. The results strongly show that Ikshusterol3-O-glucoside has a potent snake-venom neutralizing capacity and it might be a potential molecule for the therapeutic treatment for snakebites. PMID- 29171347 TI - "Watchful? For sure!" - Health professionals as family carers and their roles in patient safety AB - Background: Little is known about family caregivers in the context of adverse events that occur during the care of their significant others. Nurses as family caregivers can draw on expert specific knowledge and nursing skills. Aim: To explore how family carers who are also trained nurses experience and deal with adverse events that occur during the care of their significant others. Method: As part of a larger research project using a sequential mixed methods design, 30 semi-structured interviews were conducted with health professionals, who were also family caregivers, of whom 20 were qualified nurses. All interviews were theoretically coded, dimensionalized and contextualized. Based on the nurses' data a model was developed. Results: The model illustrates the dilemma the interviewed nurses experienced when they need to deal with safety-relevant problems. As family caregivers with expert knowledge and skills, they were vigilant in surveilling the care provided. They were quick to identify risks and vulnerable points in the system of care being delivered. However, before taking action, they carefully considered the advantages and disadvantages of intervening, and also whether or not to admit that they were health care professionals. Conclusions: In the case of events relevant to the health and safety of their significant others, family carers who are trained nurses are most likely to use their expert knowledge, in situations with a perceived high risk to health, to minimise the potential harm.

Due to impeded weaning, verbal communication is impossible. The tracheal cannula affects breathing and swallowing. The Passy Muir speaking valve (PMV) allows patients on ventilators to speak. It counteracts pharyngeal as well as laryngeal desensitization and prevents an insufficient swallowing reflex. Aim and methods: To implement the PMV, we conducted a multiprofessional practice- and quality development project. The objective was to ensure safe swallowing and communicating for ventilated patients with tracheostoma. Results: Intensive care nurses, doctors and physiotherapists assessed patient safety as being high. In nine patients with 51 PMV applications, we observed three undesirable events in terms of dyspnea and oxygen desaturation. On one occasion, it was necessary to remove the PMV. Conclusion: A combination of mandatory training for the entire treatment team, presence of two professionals during PMV application, and a newly developed guiding document resulted in a high level of patient safety. By means of PMV, ventilated intensive care patients are able to communicate verbally and to swallow better. Complications can be identified early and solved effectively. PMID- 29171350 TI - ?

AB - Tibial acceleration is a surrogate measure for impact loading and lower limb fatigue injury in runners. Triaxial accelerometers may offer reliable and practical measurement of resultant peak tibial acceleration (PTA). With such potential in mind, this study examined variability and measurement reliability of tibial acceleration in 14 runners at baseline at one week, and eight of the runners again at six months. Triaxial accelerometers were attached to the distal tibiae of runners before they ran on a treadmill for two minutes each, at speeds of 2.7, 3.0, 3.3 and 3.7 m/s in standardised shoes. Resultant PTAs were calculated for each speed and session. Reliability outcomes were presented as percentage change and effect sizes. Variability outcomes included intraclass correlation coefficients and the typical error of the measurement. Smallest worthwhile change and performance/noise ratio were also calculated. While runners demonstrated marginally lower reliability and higher variability over six months, compared to one week, in all cases the measures of reliability and variability were of 'good' to 'moderate' reliability, and 'small' to 'moderate' variability using magnitude-based inferences. We can be confident that resultant PTA can be used with runners to assess and monitor their impacts throughout a six-month intervention. PMID- 29171353 TI - The neuro control of the ovarain cycle - a hypothesis. AB - Since more than 100 years, it is known that pituitary function depends upon the function of higher centers in the brain. It was already assumed at this time that pituitary extracts could influence the gonads and postulated that their use could have practical applications. In 1926, the 'gonadal principle' was discovered revealing the regulation of ovarian function by the pituitary. The two pituitary hormones were called 'Prolan A' and 'Prolan B' which are responsible for ovarian function especially secretion of the hormones: 'lutein' and 'foliculin'. If the names of Prolan A and B are changed to follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and the names of foliculin and lutein to estrogen and progesterone, it becomes obvious that the pituitary-gonadal relationship, as we know it today, was first described in 1930. Then, the next step was the isolation, sequence and synthesis of gonadotropin releasing hormone (GnRH) responsible for the secretion of gonadotropins (Gn). It could be shown that GnRH pulse frequency has differential effects on Gn secretion: low-frequency pulses of GnRH stimulate preferentially FSH and high frequency LH secretion. The pulse frequency control depends from a subpopulation of kisspeptin neurons within the infundibular region of the hypothalamus with coexpression of neurokinin B and dynorphin A - KNDy neurons showing a negative feedback to estrogen. A second group of kisspeptide neurons in the rostral periventricular area of the third ventricle is devoid of neurokinin-B and dynorphin, mediates positive feedback from estrogen and so induces the midcycle LH-surge. Therefore, the variability in the frequency and amplitude of GnRH pulsatility is central to the differential regulation of LH and FSH and thus ovarian follicle development, the correct selection of a single dominant follicle for ovulation, the LH surge and the luteal phase. PMID- 29171354 TI - Haematology and coagulation profiles in cats with congenital portosystemic shunts. AB - Objectives The objectives of this study were, first, to report the haematological parameters and coagulation times for cats with a congenital portosystemic shunt (CPSS) and the influence of surgical shunt attenuation on these parameters; and, second, to identify any association between prolongation in coagulation profiles and incidence of perioperative haemorrhage. Methods This was a retrospective clinical study using client-owned cats with a CPSS. Signalment, shunt type (extra or intrahepatic), degree of shunt attenuation (complete or partial), haematological parameters, prothrombin time (PT) and activated partial thromboplastin time (aPTT) test results, and occurrence of any perioperative clinical bleeding complications were recorded for cats undergoing surgical treatment of a CPSS at the Royal Veterinary College, UK, between 1994 and 2011. Results Forty-two cats were included. Thirty-six (85.7%) had an extrahepatic CPSS and six (14.3%) had an intrahepatic CPSS. Preoperatively, mean cell volume (MCV) and mean cell haemoglobin (MCH) were below the reference interval (RI) in 32 (76.2%) and 31 (73.8%) cats, respectively. Red blood cell count and mean cell haemoglobin concentration (MCHC) were above the RI in 10 (23.8%) and eight (19.1%) cats, respectively. Postoperatively, there were significant increases in haematocrit ( P = 0.044), MCV ( P = 0.008) and MCH ( P = 0.002). Despite the significant increase in MCV postoperatively, the median MCV postoperatively was below the RI, indicating persistence of microcytosis. Preoperatively, PT was above the upper RI in 14 cats (87.5%), and aPTT was above the upper RI in 11 cats (68.8%). No cat demonstrated a perioperative clinical bleeding complication. Conclusions and relevance Cats with a CPSS are likely to present with a microcytosis, but rarely present with anaemia, leukocytosis or thrombocytopenia. Surgical attenuation of the CPSS results in a significant increase in the HCT and MCV. Coagulation profiles in cats with a CPSS are likely to be prolonged, irrespective of shunt type, but do not appear to be associated with an increased risk of clinical bleeding. PMID- 29171355 TI - Overweight adult cats have significantly lower voluntary physical activity than adult lean cats. AB - Objectives The objectives of the current pilot study were to evaluate whether body condition score (BCS) and body weight are significantly related to physical activity counts, and to evaluate potential interaction between BCS and voluntary physical activity measured over a 14 day period. Methods Ten (five lean, five overweight), neutered, adult American Shorthair cats were selected for this study (median age 4 +/- 0.5 years). Cats with a BCS of ?3.0 were considered lean, whereas cats with a BCS >3.0 were considered overweight, using a 5-point scale. Cats were housed in a free-living environment with indoor/outdoor access and were individually fed once daily a commercially available dry extruded diet and allowed 1 h to eat. Voluntary physical activity was measured consecutively for 14 days using the Actical Activity Monitors that were worn parallel to the ribs and attached via a harness. Results Lean cats had a greater mean total daily voluntary physical activity ( P = 0.0059), and a greater voluntary physical activity during light ( P = 0.0023) and dark ( P = 0.0446) periods, with overweight cats having 60% of the physical activity of lean cats. Lean cats were more active before feeding and during animal care procedures. These data suggest that lean cats have a greater anticipatory physical activity prior to feeding and are more eager to have social interaction with humans than overweight cats. A significant interaction was observed between day of physical activity measurement and BCS for total daily voluntary physical activity ( P = 0.0133) and activity during the light period ( P = 0.0016) where lean cats were consistently more active than overweight cats. In general, cats were more active during weekdays vs weekends. Conclusions and relevance The results of this study suggest that overweight cats are less active than lean cats and that voluntary physical activity level appears to be influenced by social interaction with humans. PMID- 29171357 TI - Parents' perceptions of children's executive functions across different cities. AB - Culture is thought to strongly influence the development of executive functions (EF), such that ethnic groups with similar cultural origins are generally assumed to exhibit comparable levels of EF performance. However, other characteristics, such as urbanization and Westernization, may also affect EF performance in societies comprising different ethnic groups, even if the ethnic groups share a similar cultural origin. The present study aimed to compare the perceptions of parents in three cities [China-Shenzhen (ZH group), China-Hong Kong (HK group), and Singapore (SG group)] regarding the EF performances of their children, all of whom share the same genetic and cultural (i.e., Chinese) origin. The study recruited 95 children aged 5-6 years (ZH group = 32; HK group = 32; SG group = 31). Their parents were invited to complete the Behavior Rating Inventory of Executive Function (BRIEF). The ZH group had significantly lower BRIEF scores compared to both the HK and SG groups. However, the BRIEF scores of the HK and SG groups only differed significantly in terms of the Organization of Materials domain. The results suggest city-related differences in parents' perceptions of their children's EF performances, despite their similar genetic and cultural backgrounds. We additionally discuss further interpretations of our results and the limitations of this study. PMID- 29171356 TI - Antifatigue properties of tanshinone IIA in mice subjected to the forced swimming test. AB - CONTEXT: Tanshinone IIA (Tan IIA) is a constituent of Danshen Salvia miltiorrhiza Bunge (Lamiaceae); however, its antifatigue activity remains unclear. OBJECTIVE: To study the antifatigue properties of Tan IIA and its underlying mechanisms. MATERIALS AND METHODS: In program I, three mouse groups were separately subjected to three gavages with 0, 1 and 6 mg/kg Tan IIA and forced swimming test (FST) weekly for 8 weeks; in program II, one gavage with 0, 2 and 10 mg/kg Tan IIA was administered plus FST weekly for 4 weeks. Serum glucose, lactate, superoxide dismutase (SOD), malondialdehyde (MDA) and blood urea nitrogen (BUN) were determined after final FST. RESULTS: Tan IIA significantly prolonged swimming durations in program I but not in program II. Swimming times were 3208 +/- 1054 and 2443 +/- 1054 s for the 1 and 6 mg/kg treatments and 856 +/- 292 s for the vehicle control. The two doses significantly reduced serum glucose levels (40.3 +/- 8.5 and 60.0 1 +/- 11.8 mg/kg) and lactate levels (61.3 +/- 27.5 and 68.8 +/- 8.5 mg/kg) in treated mice compared with those in control mice (137.5 +/- 38.6 mg/kg and 122.7 +/- 18.2 mg/kg, respectively). However, no significant differences were observed regarding SOD, MDA or BUN levels. DISCUSSION AND CONCLUSIONS: Tan IIA has antifatigue activity and is associated with reductions in serum glucose and lactate levels. Further studies should assess muscle hypertrophy and efficient aerobic glycolysis caused by Tan IIA. Tan IIA has potential as a pharmacological agent for fatigue resistance.

AB - AIM: To further characterize the pharmacokinetics of Xtampza(r) ER. SUBJECTS & METHODS: This was an open-label, randomized, active-controlled, five-treatment, five-period, naltrexone-blocked, cross-over study. Healthy subjects received five equivalent oxycodone doses: Xtampza ER (intact or crushed), OxyContin(r) (intact or crushed) or immediate-release (IR) oxycodone (crushed). Blood samples were collected to assess oxycodone concentrations. RESULTS: Crushed and intact Xtampza ER resulted in lower peak plasma concentrations compared with crushed oxycodone IR; crushed and intact Xtampza ER were bioequivalent. Crushed OxyContin exhibited a rapid increase in plasma oxycodone and was bioequivalent to crushed oxycodone IR. CONCLUSION: This second pharmacokinetic study demonstrated that Xtampza ER maintains its ER properties after crushing, unlike OxyContin, which failed to retain its ER properties after crushing.

PMID- 29171359 TI - Effects of alteplase for acute stroke according to criteria defining the European Union and United States marketing authorizations: Individual-patient-data meta analysis of randomized trials. AB - Background The recommended maximum age and time window for intravenous alteplase treatment of acute ischemic stroke differs between the Europe Union and United States. Aims We compared the effects of alteplase in cohorts defined by the current Europe Union or United States marketing approval labels, and by hypothetical revisions of the labels that would remove the Europe Union upper age limit or extend the United States treatment time window to 4.5 h. Methods We assessed outcomes in an individual-patient-data meta-analysis of eight randomized trials of intravenous alteplase (0.9 mg/kg) versus control for acute ischemic stroke. Outcomes included: excellent outcome (modified Rankin score 0-1) at 3-6 months, the distribution of modified Rankin score, symptomatic intracerebral hemorrhage, and 90-day mortality. Results Alteplase increased the odds of modified Rankin score 0-1 among 2449/6136 (40%) patients who met the current European Union label and 3491 (57%) patients who met the age-revised label (odds ratio 1.42, 95% CI 1.21-1.68 and 1.43, 1.23-1.65, respectively), but not in those outside the age-revised label (1.06, 0.90-1.26). By 90 days, there was no increased mortality in the current and age-revised cohorts (hazard ratios 0.98, 95% CI 0.76-1.25 and 1.01, 0.86-1.19, respectively) but mortality remained higher outside the age-revised label (1.19, 0.99-1.42). Similarly, alteplase increased the odds of modified Rankin score 0-1 among 1174/6136 (19%) patients who met the current US approval and 3326 (54%) who met a 4.5-h revised approval (odds ratio 1.55, 1.19-2.01 and 1.37, 1.17-1.59, respectively), but not for those outside the 4.5-h revised approval (1.14, 0.97-1.34). By 90 days, no increased mortality remained for the current and 4.5-h revised label cohorts (hazard ratios 0.99, 0.77-1.26 and 1.02, 0.87-1.20, respectively) but mortality remained higher outside the 4.5-h revised approval (1.17, 0.98-1.41). Conclusions An age-revised European Union label or 4.5-h-revised United States label would each increase the number of patients deriving net benefit from alteplase by 90 days after acute ischemic stroke, without excess mortality. PMID- 29171360 TI - Canadian stroke best practice consensus statement: Secondary stroke prevention during pregnancy. AB - The Canadian Stroke Best Practice Consensus Statement: Secondary Stroke Prevention during Pregnancy, is the first of a two-part series devoted to stroke in pregnancy. This document focuses on unique aspects of secondary stroke prevention in a woman with a prior history of stroke or transient ischemic attack who is, or is planning to become, pregnant. Although stroke is relatively rare in this cohort, several aspects of pregnancy can increase stroke risk during or immediately after pregnancy. The rationale for the development of this consensus statement is based on the premise that stroke in this group requires a specifically-tailored management approach. No other broad-based, stroke-specific guidelines or consensus statements exist currently. Underpinning the development of this document was the concept that maternal health is vital for fetal wellbeing; therefore, management decisions should be based on the confluence of two clinical considerations: (a) decisions that would be made if the patient was not pregnant and (b) decisions that would be made if the patient had not had a stroke. While empirical research in this area is limited, this consensus document is based on the best available literature and guided by expert consensus. Issues addressed in this document include general management considerations for secondary stroke prevention, the use of antithrombotics, blood pressure management, lipid management, diabetes care, and management for specific ischemic stroke etiologies in pregnancy. The focus is on maternal and fetal health while minimizing risks of a recurrent stroke, through counseling, monitoring, and the safety of select pharmacotherapy. These statements are appropriate for health care professionals across all disciplines. PMID- 29171361 TI - Canadian stroke best practice recommendations: Secondary prevention of stroke, sixth edition practice guidelines, update 2017. AB - The 2017 update of The Canadian Stroke Best Practice Recommendations for the Secondary Prevention of Stroke is a collection of current evidence-based recommendations intended for use by clinicians across a wide range of settings. The goal is to provide guidance for the prevention of ischemic stroke recurrence through the identification and management of modifiable vascular risk factors. Recommendations include those related to diagnostic testing, diet and lifestyle, smoking, hypertension, hyperlipidemia, diabetes, antiplatelet and anticoagulant therapies, carotid artery disease, atrial fibrillation, and other cardiac conditions. Notable changes in this sixth edition include the development of core elements for delivering secondary stroke prevention services, the addition of a section on cervical artery dissection, new recommendations regarding the management of patent foramen ovale, and the removal of the recommendations on management of sleep apnea. The Canadian Stroke Best Practice Recommendations include a range of supporting materials such as implementation resources to facilitate the adoption of evidence to practice, and related performance measures to enable monitoring of uptake and effectiveness of the recommendations. The guidelines further emphasize the need for a systems approach to stroke care, involving an interprofessional team, with access to specialists regardless of patient location, and the need to overcome geographic barriers to ensure equity in access within a universal health care system. PMID- 29171362 TI - Complications of endovascular treatment for acute ischemic stroke: Prevention and management. AB - Endovascular mechanical thrombectomy (MT) for the treatment of acute stroke due to large vessel occlusion has evolved significantly with the publication of multiple positive thrombectomy trials. MT is now a recommended treatment for acute ischemic stroke. Mechanical thrombectomy is associated with a number of intra-procedural or post-operative complications, which need to be minimized and effectively managed to maximize the benefits of thrombectomy. Procedural complications include: access-site problems (vessel/nerve injury, access-site hematoma and groin infection); device-related complications (vasospasm, arterial perforation and dissection, device detachment/misplacement); symptomatic intracerebral hemorrhage; subarachnoid hemorrhage; embolization to new or target vessel territory. Other complications include: anesthetic/contrast-related, post operative hemorrhage, extra-cranial hemorrhage and pseudoaneurysm. Some complications are life-threatening and many lead to increased length of stay in intensive care and stroke units. Complications increase costs and delay the commencement of rehabilitation. Some may be preventable; the impact of others can be minimized with early detection and appropriate management. Both neurointerventionists and stroke specialists need to be aware of the risk factors, strategies for prevention, and management of these complications. With the increasing use of mechanical thrombectomy for the treatment of acute ischemic stroke, incidence and outcome of complications will need to be carefully monitored by stroke teams. In this narrative review, we examine the frequency of complications of MT in the treatment of acute ischemic stroke with an emphasis on periprocedural complications. Overall, from recent randomized controlled trials, the risk of complications with sequelae for patient from mechanical thrombectomy is ~15%. We discuss the management of complications and identify areas with limited evidence, which need further research. Search strategy and selection criteria Relevant evidence was found by searches of Medline and Cochrane Library, reference list, cross-referencing and main journal content pages. Search terms included "brain ischemia", "acute ischemic stroke", "cerebral infarction" AND "mechanical thrombectomy", "endovascular therapy", "endovascular treatment", "endovascular embolectomy", "intra-arterial" AND "randomized controlled trial", "non-randomised trials", "observational studies" AND "complications", "procedural complications", "peri-procedural complications", "device-related complications", "management", "treatment", "outcome". The search included only human studies, and was limited to studies published in English between January 2014 and November 2016. The final reference list was selected on the basis of relevance to the topics covered in the Review. Guidelines for management of acute ischaemic stroke by the American Heart Association, the European Stroke Organisation, multi disciplinary guidelines and the National Institute for Health and Care Excellence (NICE) were also reviewed.

PMID- 29171364 TI - Endovascular embolization of branch-incorporated cerebral aneurysms. AB - Objectives The aim of this study was to examine the feasibility, technique, and clinical and angiographic outcomes of endovascular coiling to treat a cerebral aneurysm with a branch incorporated into the aneurysmal wall. Methods From 2012 to 2016, 25 patients with 26 cerebral aneurysms having a branch incorporated into the aneurysm (9 unruptured, 17 ruptured) were treated to prevent rupture or re bleeding from the sac while preserving the incorporated branch by using single catheter ( n = 18), balloon-remodeling ( n = 4), stent-assisted coiling ( n = 3), or double-catheter ( n = 1) techniques. Results Endovascular coiling was conducted in 26 procedures without angiographic occlusion of the incorporated branch. Post-embolization angiography revealed near-complete occlusion ( n = 8; 30.7%), neck remnant ( n = 13; 50%), and incomplete occlusion ( n = 5; 19.3%) aneurysms. Thromboembolisms were observed in four (15.4%) patients during or after the procedure. A procedure-related neurological deficit was observed in one (3.8%) patient. When patients with a preictal modified Rankin Scale (mRS) score of 3 presenting with grade 5 subarachnoid hemorrhage were excluded, all patients had favorable outcomes (mRS 0-2). Six (23.1%) recurrent aneurysms were observed during follow-up, five of which were treated endovascularly at 5-22 months without complication. The location of an aneurysm at the ICA-posterior communicating artery associated with the dominant-type posterior communicating artery was significantly associated with recurrence ( p = 0.041). Conclusions Cerebral aneurysms with an incorporated branch were safely treated using conventional endovascular coiling. However, treatment durability was unsatisfactory, especially for dominant-type ICA-posterior communicating artery aneurysms. PMID- 29171365 TI - [Distal femur fracture in a woman with a lower limb prosthesis.] AB - BACKGROUND: People who use a lower limb prosthesis can fracture their distal femur after a trivial fall; however, this kind of fracture is uncommon. CASE DESCRIPTION: A 53-year-old woman with a trans-tibial prosthesis fell in her kitchen. She felt pain just above the socket of the prosthesis, was unable to get up and her knee and leg were swollen. Radiographic imaging showed a distal femur fracture, for which she received a non-operative treatment with a stump cast. In consultation with the rehabilitation physician she received a conventional lower limb prosthesis after consolidation of the fracture. She mobilised adequately and was able to resume her activities at home and at work. CONCLUSION: Distal femur fractures in patients with a lower limb prosthesis can be recognised through pain just above the socket of the prosthesis. Conservative treatment, including the use of a stump cast, followed by mobilisation with an adapted prosthesis under supervision of a rehabilitation physician often results in a good outcome in terms of functionality. PMID- 29171366 TI - [Palmar and axillary hyperhidrosis in children: endoscopic thoracic sympathectomy using clips for an underestimated problem]. AB - BACKGROUND: Palmar and axillary hyperhidrosis are defined as perspiration exceeding the body's 'normal' physiological need for thermal regulation. This condition affects about 1% of adolescents and children and may lead to psychosocial problems and poor school performance. CASE DESCRIPTION: We carried out an endoscopic thoracic sympathectomy (ETS) with clips in a 14-year-old girl and a 16-year-old girl who suffered from debilitating palmar and axillary hyperhidrosis. They were able to quickly resume their general daily activities and both were free of symptoms during an outpatient visit after 6 weeks. CONCLUSION: ETS using clips is a safe, relatively simple and effective technique, which may provide a permanent solution. ETS can be an option in case of therapy resistant debilitating hyperhidrosis. This surgical procedure should be carefully considered, possible causes should be excluded and ETS should not be offered as the first treatment option for children.

AB - A 69-year-old woman with right-sided flank pain, probably based on a ureteropelvic junction obstruction, underwent JJ-catheter placement under fluoroscopic guidance. X-ray showed an appendix filled with shot pellets. This phenomenon has been described earlier in Eskimo hunters, who were known to accidently swallow shot pellets lodged in hunted animals. Shot pellet accumulation can result in appendicitis perforata or lead poisoning.

In the Netherlands, trisomy 18 is described as a lethal condition leading to death during or immediately after birth. The Dutch course of action for trisomy 18 is termination of pregnancy, almost without exception, or passive treatment without medical interventions. But that approach might be outdated. We present a case that inspired physicians and parents to rethink the perception of trisomy 18. PMID- 29171369 TI - [Can sick leave be predicted in patients with non-traumatic arm, neck and/or shoulder complaints?] AB - OBJECTIVES: Impediments due to complaints of non-traumatic arm, neck and/or shoulder (CANS) during work often leads to consultation in primary care. This study examines the occurrence of sick leave among workers with new CANS, and evaluates sick leave trajectories and their characteristics. METHODS: This prospective 2-year cohort study included workers with a new CANS presenting in general practice. Participants filled out postal questionnaires on sick leave at 6-monthly intervals. Latent class growth mixture modelling was used to identify distinct trajectories of sick leave. Multinomial regression analyses identified characteristics of the subgroups. RESULTS: During follow-up, of the 533 participants 190 reported at least one episode of sick leave due to CANS. Three sick leave trajectories were distinguished: (a) 'low risk' trajectory (n = 366), with a constant low probability over time; (b) 'intermediate risk' trajectory, with a high probability at first consultation followed by a steep decrease in probability of sick leave (n = 122); (c) 'high risk' trajectory (n = 45), with a constant high probability of sick leave. Compared to the 'low-risk' trajectory, the other trajectories were characterised by more functional limitations, less specific diagnoses, more work-related symptoms and low coworker support. Specific for the 'high-risk' subgroup were more recurrent symptoms, more musculoskeletal comorbidity, high score on somatisation and low score on job demands. CONCLUSIONS: Three trajectories of sick leave were distinguished, graded from favourable to unfavourable. Several complaint-related and work-related factors and somatisation contributed modestly to identify an unfavourable trajectory of sick leave when presenting in primary care with CANS.

AB - Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are both part of a spectrum of serious mucocutaneous disorders, most often caused by drugs, with a high morbidity and mortality. In the acute stage, serious skin and mucocutaneous lesions with painful blistering, erosions and systemic involvement present the main focus of attention. The severity of skin manifestations in the acute stage, however, does not necessarily correlate with that of the mucosal lesions. Most feared are long-term sequelae, especially chronic eye involvement, which can be highly disabling. Here, we illustrate the importance of daily evaluation, early recognition and treatment of eye involvement in the acute stage of SJS/TEN, even when skin manifestations and/or initial eye involvement are relatively mild. Timely performed amniotic membrane transplantation in the acute stage can limit irreversible damage, caused by chronic inflammation, and therefore prevent cicatrisation at a later stage.

AB - - Every day medication is administered to thousands of hospital inpatients, and medication administration errors can occur.- Interventions to reduce medication administration errors have been developed and tested; these include training, double-checking procedures, and technological solutions (such as smart infusion pumps and barcode-controlled drug administration).- Most of the studies that investigated these interventions were small, meaning it is unclear which intervention is the most effective. More research is needed to identify the best solutions. PMID- 29171372 TI - [Two pulmonary lesions on an X-ray of the chest].

One week after treatment with furosemide, the pulmonary lesions had disappeared completely. PMID- 29171373 TI - [Is our treatment of well-differentiated thyroid cancer too aggressive? Hemithyroidectomy versus total thyroidectomy]. AB - Recent literature shows that hemithyroidectomy is a safe alternative for total thyroidectomy in the treatment of patients with well-differentiated thyroid cancer up to 4 cm in diameter and a low risk of recurrence. According to criteria of the 2015 American Thyroid Association guidelines, more than 28% of patients with well-differentiated thyroid cancer of a Dutch cohort would be eligible for hemithyroidectomy instead of the total thyroidectomy they actually underwent. However, standardisation and high quality pre- and postoperative diagnostics are required for responsible implementation of this new guideline in Dutch healthcare.

AB - BACKGROUND: Toxic epidermal necrolysis (TEN) is a rare disease that is characterised by epidermal loss, often as a result of medication use - particularly sulfonamides and anti-epileptics. People of South-East Asian descent are at increased risk of developing TEN since they may carry the HLA-B*1502 allele. CASE DESCRIPTION: A 61-year-old female of Indonesian descent developed TEN due to carbamazepine use, resulting in admission to the intensive care department of a specialised burn centre in the Netherlands. She was successfully treated with high-dose prednisone and local therapy for the skin disorder. CONCLUSION: The US Food and Drug Administration advises screening of patients of South-East Asian descent for HLA-B*1502 prior to initiation of treatment with TEN related medication. In the Netherlands, screening for this allele is currently not mandatory. PMID- 29171375 TI - [Spondylodiscitis as a rare manifestation of gout]. AB - BACKGROUND: Spondylodiscitis is usually caused by microorganisms, but there are also non-infectious causes. CASE DESCRIPTION: We are describing an 84-year-old man with severe pain in the side and elevated inflammation parameters. MRI of the spinal column yielded a picture suggesting spondylodiscitis. Repeated peripheral cultures and culture of a vertebral biopsy did not yield a pathogen. Intravenous antibiotics had no effect on symptoms or inflammation parameters. When the physical examination was repeated, we found arthritis in the feet and tophi. Microscopic examination of a new vertebral biopsy found urate crystals. This meant we were dealing with spondylodiscitis as manifestation of gout. Treatment with colchicine was highly successful. CONCLUSION: Spinal column gout is unknown, but seems to occur with some regularity. This disease can be symptom-free but may also lead to myelopathy or spondylodiscitis. In case of spondylodiscitis without demonstrated pathogen in patients with gout or risk factors for this, the vertebral biopsy should be evaluated for urate crystals or a dual-energy CT should be considered.

Focal aware seizures provide an opportunity to predict the location of the epileptic source in the brain. The impact of these seizures is often underestimated, especially if someone has previously had seizures with loss of awareness. PMID- 29171377 TI - [Off-label prescription of antipsychotics]. AB - Antipsychotic medication is frequently prescribed for off-label use in individuals with intellectual disability and elderly persons, in particular to reduce challenging behaviour. However, clear evidence for effectiveness is scarce and long-term use of antipsychotics is associated with a wide range of serious side-effects, including movement disorders and metabolic syndrome. Therefore, off label use of antipsychotics in these populations has been widely debated. Nevertheless, non-pharmacological interventions alone are not always effective and a treatment attempt with an antipsychotic is sometimes inevitable. In this commentary, it is argued that clinicians should focus on the decision-making process in prescribing antipsychotics, rather than focus on discontinuation of these medications. PMID- 29171378 TI - [Safe administration of medicines: learning from our mistakes]. AB - This issue of the Dutch Journal of Medicine (NTvG) features a review article by Van der Veen et al. on safe administration of medicines in hospitals. This topic is part of an increased focus on patient safety that started at the beginning of the 21st century, following publication of the renowned report 'To err is human'. Now, almost 20 years later, we are a little disappointed that there is still no set of interventions that can be implemented to guarantee safe administration of medicines in hospitals. Why ever not? In this commentary we discuss the main limitations of the interventions that have been studied, but also describe what we think can already be implemented without further research.

PMID- 29171379 TI - CollAborative care for Screen-Positive EldeRs with major depression (CASPER plus): a multicentred randomised controlled trial of clinical effectiveness and cost-effectiveness. AB - BACKGROUND: Depression in older adults is common and is associated with poor quality of life, increased morbidity and early mortality, and increased health and social care use. Collaborative care, a low-intensity intervention for depression that is shown to be effective in working-age adults, has not yet been evaluated in older people with depression who are managed in UK primary care. The CollAborative care for Screen-Positive EldeRs (CASPER) plus trial fills the evidence gap identified by the most recent guidelines on depression management. OBJECTIVES: To establish the clinical effectiveness and cost-effectiveness of collaborative care for older adults with major depressive disorder in primary care. DESIGN: A pragmatic, multicentred, two-arm, parallel, individually randomised controlled trial with embedded qualitative study. Participants were automatically randomised by computer, by the York Trials Unit Randomisation Service, on a 1 : 1 basis using simple unstratified randomisation after informed consent and baseline measures were collected. Blinding was not possible. SETTING: Sixty-nine general practices in the north of England. PARTICIPANTS: A total of 485 participants aged >= 65 years with major depressive disorder. INTERVENTIONS: A low-intensity intervention of collaborative care, including behavioural activation, delivered by a case manager for an average of six sessions over 7-8 weeks, alongside usual general practitioner (GP) care. The control arm received only usual GP care. MAIN OUTCOME MEASURES: The primary outcome measure was Patient Health Questionnaire-9 items score at 4 months post randomisation. Secondary outcome measures included depression severity and caseness at 12 and 18 months, the EuroQol-5 Dimensions, Short Form questionnaire-12 items, Patient Health Questionnaire-15 items, Generalised Anxiety Disorder-7 items, Connor Davidson Resilience Scale-2 items, a medication questionnaire, objective data and adverse events. Participants were followed up at 12 and 18 months. RESULTS: In total, 485 participants were randomised (collaborative care, n = 249; usual care, n = 236), with 390 participants (80%: collaborative care, 75%; usual care, 86%) followed up at 4 months, 358 participants (74%: collaborative care, 70%; usual care, 78%) followed up at 12 months and 344 participants (71%: collaborative care, 67%; usual care, 75%) followed up at 18 months. A total of 415 participants were included in primary analysis (collaborative care, n = 198; usual care, n = 217), which revealed a statistically significant effect in favour of collaborative care at the primary end point at 4 months [8.98 vs. 10.90 score points, mean difference 1.92 score points, 95% confidence interval (CI) 0.85 to 2.99 score points; p < 0.001], equivalent to a standard effect size of 0.34. However, treatment differences were not maintained in the longer term (at 12 months: 0.19 score points, 95% CI -0.92 to 1.29 score points; p = 0.741; at 18 months: < 0.01 score points, 95% CI -1.12 to 1.12 score points; p = 0.997). The study recorded details of all serious adverse events (SAEs), which consisted of 'unscheduled hospitalisation', 'other medically important condition' and 'death'. No SAEs were related to the intervention. Collaborative care showed a small but non-significant increase in quality-adjusted life-years (QALYs) over the 18-month period, with a higher cost. Overall, the mean cost per incremental QALY for collaborative care compared with usual care was L26,016; however, for participants attending six or more sessions, collaborative care appears to represent better value for money (L9876/QALY). LIMITATIONS: Study limitations are identified at different stages: design (blinding unfeasible, potential contamination), process (relatively low overall consent rate, differential attrition/retention rates) and analysis (no baseline health-care resource cost or secondary/social care data). CONCLUSION: Collaborative care was effective for older people with case-level depression across a range of outcomes in the short term though the reduction in depression severity was not maintained over the longer term of 12 or 18 months. Participants who received six or more sessions of collaborative care did benefit substantially more than those who received fewer treatment sessions but this difference was not statistically significant. FUTURE WORK RECOMMENDATIONS: Recommendations for future research include investigating the longer-term effect of the intervention. Depression is a recurrent disorder and it would be useful to assess its impact on relapse and the prevention of future case-level depression.

PMID- 29171392 TI - Clinical assessment of skin phototypes: watch your words! AB - Fitzpatrick skin phototype classification is widely used to assess risk factors for skin cancers. This skin type evaluation is easy to use in clinical practice but is not always applied as initially described, nor practiced in a standardised way. This can have implications on the results of relevant dermato epidemiological studies. To demonstrate, in a large multinational setting, that the phrasing of questions on sun sensitivity can have a strong impact on the perception and reporting of skin phototype, as well as the importance of a standardised procedure for phototype assessment. Using data collected from 48,258 screenees of the Euromelanoma campaign in six European countries from 2009 to 2011, we analysed the impact of change in the question phrasing on phototype classification in each country. Changing the wording of a question to assess the phototype of a person also significantly influenced the classification of phototypes in different countries (p<0.001 for each country). The difference essentially corresponded to a shift towards a less sun-sensitive skin type when a shorter question that did not include skin colour description was used. The only exception was Portugal where phototype was not patient-assessed and classification shifted towards a more sun-sensitive phototype. Results were statistically significant and highly consistent, irrespective of gender. The phrasing of questions on skin type is important and substantially influences reporting. A standardized procedure to classify phototypes should be used in order to obtain comparable data between studies. PMID- 29171393 TI - Characterization of skin Th17 transcriptional profiles in psoriatic patients under adalimumab biotherapy. AB - In psoriasis, a specific cytokine network has been described to play a central role in the pathophysiology of the disease. Anti-cytokine therapeutic approaches have been largely developed and TNFalpha constitutes the main target. Adalimumab is a human anti-TNFalpha monoclonal antibody that has been reported to demonstrate clinical efficacy and safety, resulting in reversal of epidermal hyperplasia and cutaneous inflammation. We aimed to analyse changes in the skin inflammatory transcriptomic profile in psoriatic patients during adalimumab therapy. In addition, the circulating cytokine profile was analysed to define systemic inflammation. Eighteen patients with chronic plaque psoriasis were treated with adalimumab. After four and 16 weeks, clinical efficacy was assessed using PASI and DLQI, and skin mRNA profiles were determined and circulating cytokines quantified. We identified a rapid effect of adalimumab therapy on a large array of Th17 cytokines of the skin, which may account for the modification of keratinocyte expression profile and clinical response. In contrast, analysis of serum cytokine concentrations was uninformative, confirming the need for characterization of local cytokines in skin lesions. Finally, in non-responders, local cytokine expression was shown to be unchanged. We show that TNFalpha inhibition in psoriasis patients treated with adalimumab has a broad effect on the expression profile of cytokines and keratinocyte markers of skin inflammation, which may account for its clinical efficacy.

PMID- 29171395 TI - Incidence and ten-year follow-up of primary cutaneous lymphomas: a single-centre cohort study. AB - BACKGROUND: Primary cutaneous lymphomas (PCLs) are a rare group of extranodal non Hodgkin lymphomas, and epidemiological data in Mediterranean countries are scarce. OBJECTIVE: To investigate the incidence and characteristics of PCL in a single tertiary referral centre in Italy. MATERIALS & METHODS: A total of 141 PCL patients, seen over a 10-year follow-up period, were investigated. RESULTS: Incidence rate of PCL was 0.8 cases/100,000 person years. T-cell lymphoma represented 78.7% of all cases, the majority being early mycosis fungoides (MF) (64%; median age: 66 years), followed by lymphomatoid papulosis (LyP) (19%; median: age 48 years), and others (median age: 72 years), including eight cases of anaplastic large CD30+ T-cell lymphoma, four CD4+ small-medium pleomorphic T cell lymphoproliferative disorder, four Sezary syndrome, one subcutaneous panniculitis-like T-cell lymphoma, one extranodal NK/T-cell lymphoma nasal-type, and one angioimmunoblastic T-cell lymphoma. B-cell lymphoma accounted for 21.3% of PCL, with 20 cases of cutaneous follicular centre B-cell (median age: 63 years), four primary cutaneous marginal zone, three primary cutaneous diffuse large B-cell, and three leg-type lymphoma. Complete remission within the first year after diagnosis occurred in 70.4% of MF, 61.9% of LyP, 78.9% of other T-cell lymphoma, and 93.1% of B-cell lymphoma cases. Based on a Cox proportional hazard regression model, age, gender, stage, and lactate dehydrogenase and beta2 microglobulin blood levels did not predict clinical remission of MF or LyP. CONCLUSIONS: The incidence and characteristics of PCL in Italy are similar to those in other European countries. PCLs may be diagnosed at very early stages with good prognosis. PMID- 29171396 TI - Sleep-related hypermotor epilepsy activated by rapid eye movement sleep. AB - Most sleep-related seizures occur during non-rapid eye movement (NREM) sleep, particularly during stage changes. Sleep-related hypermotor epilepsy (SHE) is a rare epileptic syndrome characterized by paroxysmal motor seizures, mainly arising from NREM sleep. Here, we report a patient with SHE who had seven seizures captured on video-EEG-polysomnography during REM sleep. Ictal semiology of this patient ranged from brief paroxysmal arousals to hypermotor seizures. On EEG-polysomnography, the spontaneous arousals were more frequent during REM than NREM sleep, with a considerably higher arousal index in REM sleep (20/hour). While the reason for seizures during REM sleep in this patient is unclear, we speculate that the threshold and mechanisms of arousal during different sleep stages may be related to the occurrence of seizures.

PMID- 29171397 TI - Crossing the lines between epilepsy syndromes: a myoclonic epilepsy variant with prominent eyelid myoclonia and atonic components. AB - Accurate diagnosis of a distinct epilepsy syndrome is based on well-defined electroclinical features that differentiate separate nosological entities. In clinical practice, however, syndromes may overlap and cases may present with unusual manifestations posing a diagnostic challenge. This heterogeneity has been documented in several cases presenting with eyelid myoclonia with or without absences (EMA) diagnosed either as Jeavons syndrome (JS) variants or as genetic generalised epilepsies defined by the presence of this unique clinical entity. The hallmark of JS is the triad: (1) eyelid myoclonia with or without absences, (2) eye closure-induced paroxysms, and (3) photosensitivity. The presence of massive myoclonus, intellectual disability, or slowing of the EEG background are not typical features of the syndrome and may cause delay in making the correct diagnosis. Adding to the variability of clinical features, we describe two female paediatric patients with probable genetic epilepsy who presented with EMA but demonstrated clear atypical features, such as prominent myoclonic seizures, atonic components on video-EEG, and cognitive impairment. We also note the presence of interictal and ictal posterior discharges during eyelid myoclonia in one, supporting similar previous observations leading to consideration of EMA as an occipital cortex-initiated seizure activity.

AB - BACKGROUND: Atopic dermatitis (AD) is one of the most common, chronic or chronically relapsing inflammatory skin diseases that affect children. Multiple genetic and environmental factors appear to regulate the pathogenesis of AD. OBJECTIVES: Our aim was to investigate the possible association between family, social, dieting, atopic and environmental factors and the severity of AD evaluated by SCORAD scores in children. MATERIALS & METHODS: The study group included 100 children with AD who attended a paediatric dermatology outpatient clinic with a median age of 18.5 months. The diagnosis of AD was established on the basis of the clinical criteria according to the American Dermatology Society, while the SCORAD score was used to evaluate disease severity. RESULTS: Multivariate linear regression analysis disclosed that excessive cleanliness (p<0.001), RAST level greater than 0.7 KU/l (p<0.001), breastfeeding for less than two months (p = 0.001), and the absence of an older sibling (p = 0.049) were statistically significant independent determinants for high SCORAD scores. Multivariate logistic regression analysis showed that excessive cleanliness (p<0.001) was the strongest independent risk factor for severe AD (SCORAD>36) (aOR: 59.4; 95% CI: 10.9-322.6). RAST level greater than 0.7 KU/l (aOR: 7.9; 95% CI: 1.5-41.0; p = 0.014) and severe passive smoking (aOR: 4.6; 95% CI: 1.0-22.1; p = 0.050) also showed a significant independent, but clearly weaker, association with severe AD. CONCLUSIONS: A short duration of breastfeeding, absence of older siblings, parental passive smoking, food allergens along with aeroallergens, and excessive cleanliness should be considered as negative prognostic factors, leading to a higher SCORAD score in children with AD.

AB - Limbic encephalitis associated with anti-LGI1 antibody (LGI1 encephalitis) presents with a variety of features, the most prominent of which include seizures and progressive disturbance of memory and behaviour. Although varied in semiology, recognition of the pattern of seizures in LGI1 encephalitis is important, as early diagnosis and definitive treatment may prevent subsequent development of cognitive impairment. We present a patient with LGI1 encephalitis and "faciobrachial dystonic seizures-plus", which began as classic faciobrachial dystonic seizures and progressed to focal seizures with impaired awareness, dacrystic/gelastic-like outbursts, ictal speech, manual automatisms, and autonomic signs (tachycardia). Recognition of the broad range of seizure types associated with LGI1 encephalitis is crucial for early diagnosis and definitive treatment.

AB - BACKGROUND: Malignant melanoma cases arising in tattoos have been increasingly described, however, there is no clear relationship between this practice and the development of cutaneous malignancies. OBJECTIVES: We report a new case of melanoma in a dark-blue tattoo and we review all cases of melanoma reported in the medical literature from 1938 to date. MATERIALS & METHODS: Pubmed and Google Scholar were searched using the terms "melanoma tattoo", "tattoo skin tumour" and "ink melanoma". RESULTS: In most cases, the melanoma occurred on dark blue (10/30), black (8/30), or blue ink (3/30). The Breslow thickness at diagnosis was <=1 mm in 13/30, 1-2 mm in 3/30, 2-4 mm in 2/30, >4 mm in 5/30, and Clark II in 2/30 (not available in 5/30). CONCLUSIONS: Both the incidence of melanoma and the number of tattoos have been increasing in recent years, but a possible carcinogenic effect of tattoos remains unproven. The spread of this decorative custom will make observation of melanoma in tattoos more frequent in dermatological practice, therefore these cases should be reported in national skin cancer registries.

AB - While the peripheral nervous system has the capacity to regenerate following a nerve injury, it is often at a slow rate and results in unsatisfactory recovery, leaving patients with reduced function. Many regeneration associated genes have been identified over the years, which may shed some insight into how we can manipulate this intrinsic regenerative ability to enhance repair following peripheral nerve injuries. Our lab has identified the membrane bound protease beta-site amyloid precursor protein-cleaving enzyme 1 (BACE1), or beta secretase, as a potential negative regulator of peripheral nerve regeneration. When beta secretase activity levels are abolished via a null mutation in mice, peripheral regeneration is enhanced following a sciatic nerve crush injury. Conversely, when activity levels are greatly increased by overexpressing beta secretase in mice, nerve regeneration and functional recovery are impaired after a sciatic nerve crush injury. In addition to our work, many substrates of beta secretase have been found to be involved in regulating neurite outgrowth and some have even been identified as regeneration associated genes. In this review, we set out to discuss BACE1 and its substrates with respect to axonal regeneration and speculate on the possibility of utilizing BACE1 inhibitors to enhance regeneration following acute nerve injury and potential uses in peripheral neuropathies. PMID- 29171413 TI - On the road towards the global analysis of human synapses. AB - Synapses are essential units for the flow of information in the brain. Over the last 70 years, synapses have been widely studied in multiple animal models including worms, fruit flies, and rodents. In comparison, the study of human synapses has evolved significantly slower, mainly because of technical limitations. However, three novel methods allowing the analysis of molecular, morphological, and functional properties of human synapses may expand our knowledge of the human brain. Here, we briefly describe these methods, and evaluate how the information provided by each unique approach may contribute to the functional and anatomical analysis of the synaptic component of human brain circuitries. In particular, using tissue from cryopreserved human brains, synaptic plasticity can be studied in isolated synaptosomes by fluorescence analysis of single-synapse long-term potentiation (FASS-LTP), and subpopulations of synapses can be thoroughly assessed in the ribbons of brain tissue by array tomography (AT). Currently, it is also possible to quantify synaptic density in the living human brain by positron emission tomography (PET), using a novel synaptic radio-ligand. Overall, data provided by FASS-LTP, AT, and PET may significantly contribute to the global understanding of synaptic structure and function in both healthy and diseased human brains, thus directly impacting translational research. PMID- 29171414 TI - Non-invasive electrical brain stimulation: from acute to late-stage treatment of central nervous system damage. AB - Non-invasive brain current stimulation (NIBS) is a promising and versatile tool for inducing neuroplasticity, protection and functional rehabilitation of damaged neuronal systems. It is technically simple, requires no surgery, and has significant beneficial effects. However, there are various technical approaches for NIBS which influence neuronal networks in significantly different ways. Transcranial direct current stimulation (tDCS), alternating current stimulation (ACS) and repetitive transcranial magnetic stimulation (rTMS) all have been applied to modulate brain activity in animal experiments under normal and pathological conditions. Also clinical trials have shown that tDCS, rTMS and ACS induce significant behavioural effects and can - depending on the parameters chosen - enhance or decrease brain excitability and influence performance and learning as well as rehabilitation and protective mechanisms. The diverse phaenomena and partially opposing effects of NIBS are not yet fully understood and mechanisms of action need to be explored further in order to select appropriate parameters for a given task, such as current type and strength, timing, distribution of current densities and electrode position. In this review, we will discuss the various parameters which need to be considered when designing a NIBS protocol and will put them into context with the envisaged applications in experimental neurobiology and medicine such as vision restoration, motor rehabilitation and cognitive enhancement.

AB - Emerging evidence is fueling a new appreciation of oligodendrocyte diversity that is overturning the traditional view that oligodendrocytes are a homogenous cell population. Oligodendrocytes of distinct origins, maturational stages, and regional locations may differ in their functional capacity or susceptibility to injury. One of the most unique qualities of the oligodendrocyte is its ability to produce myelin. Myelin abnormalities have been ascribed to a remarkable array of perinatal brain injuries, with concomitant oligodendrocyte dysregulation. Within this review, we discuss new insights into the diversity of the oligodendrocyte lineage and highlight their relevance in paradigms of perinatal brain injury. Future therapeutic development will be informed by comprehensive knowledge of oligodendrocyte pathophysiology that considers the particular facets of heterogeneity that this lineage exhibits.

AB - Baicalin is a flavonoid compound extracted from Scutellaria baicalensis root. Recent evidence indicates that baicalin is neuroprotective in models of ischemic stroke. Here, we investigate the neuroprotective effect of baicalin in a neonatal rat model of hypoxic-ischemic encephalopathy. Seven-day-old pups underwent left common carotid artery ligation followed by hypoxia (8% oxygen at 37 degrees C) for 2 hours, before being injected with baicalin (120 mg/kg intraperitoneally) and examined 24 hours later. Baicalin effectively reduced cerebral infarct volume and neuronal loss, inhibited apoptosis, and upregulated the expression of p-Akt and glutamate transporter 1. Intracerebroventricular injection of the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) inhibitor LY294002 30 minutes before injury blocked the effect of baicalin on p-Akt and glutamate transporter 1, and weakened the associated neuroprotective effect. Our findings provide the first evidence, to our knowledge that baicalin can protect neonatal rat brains against hypoxic-ischemic injury by upregulating glutamate transporter 1 via the PI3K/Akt signaling pathway. PMID- 29171428 TI - The role of glycogen synthase kinase 3 beta in brain injury induced by myocardial ischemia/reperfusion injury in a rat model of diabetes mellitus. AB - Myocardial ischemia/reperfusion injury can lead to severe brain injury. Glycogen synthase kinase 3 beta is known to be involved in myo-cardial ischemia/reperfusion injury and diabetes mellitus. However, the precise role of glycogen synthase kinase 3 beta in myocardial ischemia/reperfusion injury-induced brain injury is unclear. In this study, we observed the effects of glycogen synthase kinase 3 beta on brain injury induced by myocardial ischemia/reperfusion injury in diabetic rats. Rat models of diabetes mellitus were generated via intraperitoneal injection of streptozotocin. Models of myocardial ischemia/reperfusion injury were generated by occluding the anterior descending branch of the left coronary artery. Post-conditioning comprised three cycles of ischemia/reperfusion. Immunohistochemical staining and western blot assays demonstrated that after 48 hours of reperfusion, the structure of the brain was seriously damaged in the experimental rats compared with normal controls. Expression of Bax, interleukin-6, interleukin-8, terminal deoxynucleotidyl transferase dUTP nick end labeling, and cleaved caspase-3 in the brain was significantly increased, while expression of Bcl-2, interleukin-10, and phospho glycogen synthase kinase 3 beta was decreased. Diabetes mellitus can aggravate inflammatory reactions and apoptosis. Ischemic post-conditioning with glycogen synthase kinase 3 beta inhibitor lithium chloride can effectively reverse these changes. Our results showed that myocardial ischemic post-conditioning attenuated myocardial ischemia/reperfusion injury-induced brain injury by activating glyco gen synthase kinase 3 beta. According to these results, glycogen synthase kinase 3 beta appears to be an important factor in brain injury induced by myocardial ischemia/reperfusion injury. PMID- 29171429 TI - Age-related connectivity differences between attention deficit and hyperactivity disorder patients and typically developing subjects: a resting-state functional MRI study. AB - Attention deficit and hyperactivity disorder (ADHD) is a disorder characterized by behavioral symptoms including hyperactivity/impulsivity among children, adolescents, and adults. These ADHD related symptoms are influenced by the complex interaction of brain networks which were under explored. We explored age related brain network differences between ADHD patients and typically developing (TD) subjects using resting state fMRI (rs-fMRI) for three age groups of children, adolescents, and adults. We collected rs-fMRI data from 184 individuals (27 ADHD children and 31 TD children; 32 ADHD adolescents and 32 TD adolescents; and 31 ADHD adults and 31 TD adults). The Brainnetome Atlas was used to define nodes in the network analysis. We compared three age groups of ADHD and TD subjects to identify the distinct regions that could explain age-related brain network differences based on degree centrality, a well-known measure of nodal centrality. The left middle temporal gyrus showed significant interaction effects between disease status (i.e., ADHD or TD) and age (i.e., child, adolescent, or adult) (P < 0.001). Additional regions were identified at a relaxed threshold (P < 0.05). Many of the identified regions (the left inferior frontal gyrus, the left middle temporal gyrus, and the left insular gyrus) were related to cognitive function. The results of our study suggest that aberrant development in cognitive brain regions might be associated with age-related brain network changes in ADHD patients. These findings contribute to better understand how brain function influences the symptoms of ADHD. PMID- 29171430 TI - Toxic effect of acrylamide on the development of hippocampal neurons of weaning rats. AB - Although numerous studies have examined the neurotoxicity of acrylamide in adult animals, the effects on neuronal development in the embryonic and lactational periods are largely unknown. Thus, we examined the toxicity of acrylamide on neuronal development in the hippocampus of fetal rats during pregnancy. Sprague Dawley rats were mated with male rats at a 1:1 ratio. Rats were administered 0, 5, 10 or 20 mg/kg acrylamide intragastrically from embryonic days 6-21. The gait scores were examined in pregnant rats in each group to analyze maternal toxicity. Eight weaning rats from each group were also euthanized on postnatal day 21 for follow-up studies. Nissl staining was used to observe histological change in the hippocampus. Immunohistochemistry was conducted to observe the condition of neurites, including dendrites and axons. Western blot assay was used to measure the expression levels of the specific nerve axon membrane protein, growth associated protein 43, and the presynaptic vesicle membrane specific protein, synaptophysin. The gait scores of gravid rats significantly increased, suggesting that acrylamide induced maternal motor dysfunction. The number of neurons, as well as expression of growth associated protein 43 and synaptophysin, was reduced with increasing acrylamide dose in postnatal day 21 weaning rats. These data suggest that acrylamide exerts dose-dependent toxic effects on the growth and development of hippocampal neurons of weaning rats. PMID- 29171431 TI - Effect of erythropoietin combined with hypothermia on serum tau protein levels and neurodevelopmental outcome in neonates with hypoxic-ischemic encephalopathy. AB - Although hypothermia therapy is effective to treat neonatal hypoxic-ischemic encephalopathy, many neonatal patients die or suffer from severe neurological dysfunction. Erythropoietin is considered one of the most promising neuroprotective agents. We hypothesized that erythropoietin combined with hypothermia will improve efficacy of neonatal hypoxic-ischemic encephalopathy treatment. In this study, 41 neonates with moderate/severe hypoxic-ischemic encephalopathy were randomly divided into a control group (hypothermia alone for 72 hours, n = 20) and erythropoietin group (hypothermia + erythropoietin 200 IU/kg for 10 days, n = 21). Our results show that compared with the control group, serum tau protein levels were lower and neonatal behavioral neurological assessment scores higher in the erythropoietin group at 8 and 12 days. However, neurodevelopmental outcome was similar between the two groups at 9 months of age. These findings suggest that erythropoietin combined with hypothermia reduces serum tau protein levels and improves neonatal behavioral neurology outcome but does not affect long-term neurodevelopmental outcome. PMID- 29171432 TI - Locomotor analysis identifies early compensatory changes during disease progression and subgroup classification in a mouse model of amyotrophic lateral sclerosis. AB - Amyotrophic lateral sclerosis is a motoneuron degenerative disease that is challenging to diagnose and presents with considerable variability in survival. Early identification and enhanced understanding of symptomatic patterns could aid in diagnosis and provide an avenue for monitoring disease progression. Use of the mSOD1G93A mouse model provides control of the confounding environmental factors and genetic heterogeneity seen in amyotrophic lateral sclerosis patients, while investigating underlying disease-induced changes. In the present study, we performed a longitudinal behavioral assessment paradigm and identified an early hindlimb symptom, resembling the common gait abnormality foot drop, along with an accompanying forelimb compensatory mechanism in the mSOD1G93A mouse. Following these initial changes, mSOD1 mice displayed a temporary hindlimb compensatory mechanism resembling an exaggerated steppage gait. As the disease progressed, these compensatory mechanisms were not sufficient to sustain fundamental locomotor parameters and more severe deficits appeared. We next applied these initial findings to investigate the inherent variability in B6SJL mSOD1G93A survival. We identified four behavioral variables that, when combined in a cluster analysis, identified two subpopulations with different disease progression rates: a fast progression group and a slow progression group. This behavioral assessment paradigm, with its analytical approaches, provides a method for monitoring disease progression and detecting mSOD1 subgroups with different disease severities. This affords researchers an opportunity to search for genetic modifiers or other factors that likely enhance or slow disease progression. Such factors are possible therapeutic targets with the potential to slow disease progression and provide insight into the underlying pathology and disease mechanisms. PMID- 29171433 TI - Protective effects of Bushen Tiansui decoction on hippocampal synapses in a rat model of Alzheimer's disease. AB - Bushen Tiansui decoction is composed of six traditional Chinese medicines: Herba Epimedii, Radix Polygoni multiflori, Plastrum testudinis, Fossilia Ossis Mastodi, Radix Polygalae, and Rhizoma Acorus tatarinowii. Because Bushen Tiansui decoction is effective against amyloid beta (Abeta) toxicity, we hypothesized that it would reduce hippocampal synaptic damage and improve cognitive function in Alzheimer's disease. To test this hypothesis, we used a previously established animal model of Alzheimer's disease, that is, microinjection of aggregated Abeta25-35 into the bilateral brain ventricles of Sprague-Dawley rats. We found that long-term (28 days) oral administration of Bushen Tiansui decoction (0.563, 1.688, and 3.375 g/mL; 4 mL/day) prevented synaptic loss in the hippocampus and increased the expression levels of synaptic proteins, including postsynaptic density protein 95, the N-methyl-D-aspartate receptor 2B subunit, and Shank1. These results suggested that Bushen Tiansui decoction can protect synapses by maintaining the expression of these synaptic proteins. Bushen Tiansui decoction also ameliorated measures reflecting spatial learning and memory deficits that were observed in the Morris water maze (i.e., increased the number of platform crossings and the amount of time spent in the target quadrant and decreased escape latency) following intraventricular injections of aggregated Abeta25-35 compared with those measures in untreated Abeta25-35-injected rats. Overall, these results provided evidence that further studies on the prevention and treatment of dementia with this traditional Chinese medicine are warranted. PMID- 29171434 TI - Nischarin-siRNA delivered by polyethylenimine-alginate nanoparticles accelerates motor function recovery after spinal cord injury. AB - A previous study by our group found that inhibition of nischarin promotes neurite outgrowth and neuronal regeneration in Neuro-2a cells and primary cortical neurons. In recent years, more and more studies have shown that nanomaterials have good prospects in treatment of spinal cord injury. We proposed that small interfering RNA targeting nischarin (Nis-siRNA) delivered by polyethyleneimine alginate (PEI-ALG) nanoparticles promoted motor function recovery in rats with spinal cord injury. Direct microinjection of 5 MUL PEI-ALG/Nis-siRNA into the spinal cord lesion area of spinal cord injury rats was performed. From day 7 after surgery, Basso, Beattie and Bresnahan score was significantly higher in rats from the PEI-ALG/Nis-siRNA group compared with the spinal cord injury group and PEI-ALG/Control-siRNA group. On day 21 after injection, hematoxylin-eosin staining showed that the necrotic area was reduced in the PEI-ALG/Nis-siRNA group. Immunohistochemistry and western blot assay results confirmed successful inhibition of nischarin expression and increased protein expression of growth associated protein-43 in the PEI-ALG/Nis-siRNA group. These findings suggest that a complex of PEI-ALG nanoparticles and Nis-siRNA effectively suppresses nischarin expression, induces expression of growth-associated protein-43, and accelerates motor function recovery after spinal cord injury. PMID- 29171435 TI - Central projections and connections of lumbar primary afferent fibers in adult rats: effectively revealed using Texas red-dextran amine tracing. AB - Signals from lumbar primary afferent fibers are important for modulating locomotion of the hind-limbs. However, silver impregnation techniques, autoradiography, wheat germ agglutinin-horseradish peroxidase and cholera toxin B subunit-horseradish peroxidase cannot image the central projections and connections of the dorsal root in detail. Thus, we injected 3-kDa Texas red dextran amine into the proximal trunks of L4 dorsal roots in adult rats. Confocal microscopy results revealed that numerous labeled arborizations and varicosities extended to the dorsal horn from T12-S4, to Clarke's column from T10-L2, and to the ventral horn from L1-5. The labeled varicosities at the L4 cord level were very dense, particularly in laminae I-III, and the density decreased gradually in more rostral and caudal segments. In addition, they were predominately distributed in laminae I-IV, moderately in laminae V-VII and sparsely in laminae VIII-X. Furthermore, direct contacts of lumbar afferent fibers with propriospinal neurons were widespread in gray matter. In conclusion, the projection and connection patterns of L4 afferents were illustrated in detail by Texas red dextran amine-dorsal root tracing. PMID- 29171436 TI - End-to-side neurorrhaphy repairs peripheral nerve injury: sensory nerve induces motor nerve regeneration. AB - End-to-side neurorrhaphy is an option in the treatment of the long segment defects of a nerve. It involves suturing the distal stump of the disconnected nerve (recipient nerve) to the side of the intimate adjacent nerve (donor nerve). However, the motor-sensory specificity after end-to-side neurorrhaphy remains unclear. This study sought to evaluate whether cutaneous sensory nerve regeneration induces motor nerves after end-to-side neurorrhaphy. Thirty rats were randomized into three groups: (1) end-to-side neurorrhaphy using the ulnar nerve (mixed sensory and motor) as the donor nerve and the cutaneous antebrachii medialis nerve as the recipient nerve; (2) the sham group: ulnar nerve and cutaneous antebrachii medialis nerve were just exposed; and (3) the transected nerve group: cutaneous antebrachii medialis nerve was transected and the stumps were turned over and tied. At 5 months, acetylcholinesterase staining results showed that 34% +/- 16% of the myelinated axons were stained in the end-to-side group, and none of the myelinated axons were stained in either the sham or transected nerve groups. Retrograde fluorescent tracing of spinal motor neurons and dorsal root ganglion showed the proportion of motor neurons from the cutaneous antebrachii medialis nerve of the end-to-side group was 21% +/- 5%. In contrast, no motor neurons from the cutaneous antebrachii medialis nerve of the sham group and transected nerve group were found in the spinal cord segment. These results confirmed that motor neuron regeneration occurred after cutaneous nerve end-to-side neurorrhaphy. PMID- 29171437 TI - miR-30c promotes Schwann cell remyelination following peripheral nerve injury. AB - Differential expression of miRNAs occurs in injured proximal nerve stumps and includes miRNAs that are firstly down-regulated and then gradually up-regulated following nerve injury. These miRNAs might be related to a Schwann cell phenotypic switch. miR-30c, as a member of this group, was further investigated in the current study. Sprague-Dawley rats underwent sciatic nerve transection and proximal nerve stumps were collected at 1, 4, 7, 14, 21, and 28 days post injury for analysis. Following sciatic nerve injury, miR-30c was down-regulated, reaching a minimum on day 4, and was then upregulated to normal levels. Schwann cells were isolated from neonatal rat sciatic nerve stumps, then transfected with miR-30c agomir and co-cultured in vitro with dorsal root ganglia. The enhanced expression of miR-30c robustly increased the amount of myelin-associated protein in the co-cultured dorsal root ganglia and Schwann cells. We then modeled sciatic nerve crush injury in vivo in Sprague-Dawley rats and tested the effect of perineural injection of miR-30c agomir on myelin sheath regeneration. Fourteen days after surgery, sciatic nerve stumps were harvested and subjected to immunohistochemistry, western blot analysis, and transmission electron microscopy. The direct injection of miR-30c stimulated the formation of myelin sheath, thus contributing to peripheral nerve regeneration. Overall, our findings indicate that miR-30c can promote Schwann cell myelination following peripheral nerve injury. The functional study of miR-30c will benefit the discovery of new therapeutic targets and the development of new treatment strategies for peripheral nerve regeneration. PMID- 29171438 TI - In vitro neuroprotective effects of ciliary neurotrophic factor on dorsal root ganglion neurons with glutamate-induced neurotoxicity. AB - Ciliary neurotrophic factor has neuroprotective effects mediated through signal transducer and Janus kinase (JAK) 2/activator of transcription 3 (STAT3) and phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathways. Whether ciliary neurotrophic factor is neuroprotective for glutamate-induced excitotoxicity of dorsal root ganglion neurons is poorly understood. In the present study, the in vitro neuroprotective effects of ciliary neurotrophic factor against glutamate induced excitotoxicity were determined in a primary culture of dorsal root ganglion neurons from Wistar rat embryos at embryonic day 15. Whether the JAK2/STAT3 and PI3K/Akt signaling pathways were related to the protective effects of ciliary neurotrophic factor was also determined. Glutamate exposure inhibited neurite outgrowth, cell viability, and growth-associated protein 43 expression and promoted apoptotic neuronal cell death, all of which were reversed by the administration of exogenous ciliary neurotrophic factor. Additionally, preincubation with either JAK2 inhibitor AG490 or PI3K inhibitor LY294002 blocked the neuroprotective effect of ciliary neurotrophic factor. These data indicate that the two pathways JAK2/STAT3 and PI3K/Akt play major roles in mediating the in vitro neuroprotective effects of ciliary neurotrophic factor on dorsal root ganglion neurons with glutamate-induced neurotoxicity. PMID- 29171439 TI - Effect of glial cells on remyelination after spinal cord injury. AB - Remyelination plays a key role in functional recovery of axons after spinal cord injury. Glial cells are the most abundant cells in the central nervous system. When spinal cord injury occurs, many glial cells at the lesion site are immediately activated, and different cells differentially affect inflammatory reactions after injury. In this review, we aim to discuss the core role of oligodendrocyte precursor cells and crosstalk with the rest of glia and their subcategories in the remyelination process. Activated astrocytes influence proliferation, differentiation, and maturation of oligodendrocyte precursor cells, while activated microglia alter remyelination by regulating the inflammatory reaction after spinal cord injury. Understanding the interaction between oligodendrocyte precursor cells and the rest of glia is necessary when designing a therapeutic plan of remyelination after spinal cord injury.

AB - The fornix, which connects the medial temporal lobe and the medial diencephalon, is involved in episodic memory as an important part of the Papez circuit. The mechanisms of recovery of an injured fornix revealed by diffusion tensor tractography in the five studies are summarized as follows: 1) recovery through the nerve tract from an injured fornical crus to the medial temporal lobe via the normal pathway of the fornical crus; 2) recovery through the nerve tract originating from an ipsi-lesional fornical body connected to the ipsi-lesional medial temporal lobe via the splenium of the corpus callosum; 3) recovery through the nerve tract from the ipsi-lesional fornical body extending to the contra lesional medial temporal lobe via the splenium of the corpus callosum; 4) recovery through the nerve tract originating from the ipsi-lesional fornical column connected to the ipsi-lesional medial temporal lobe; and 5) recovery through the nerve tract originating from the contra-lesional fornical column connected to the ipsi-lesional medial temporal lobe via the contra-lesional medial temporal lobe and the splenium of the corpus callosum. These diffusion tensor tractography studies on mechanisms of recovery of injured fornical crus appeared to provide useful information for clinicians caring for patients with brain injury, however, studies on this topic are still in the beginning stages. PMID- 29171440 TI - Brain-derived neurotropic factor and GABAergic transmission in neurodegeneration and neuroregeneration. AB - Neurotoxicity induced by stress, radiation, chemicals, or metabolic diseases, is commonly associated with excitotoxicity, oxidative stress, and neuroinflammation. The pathological process of neurotoxicity induces neuronal death, interrupts synaptic plasticity in the brain, and is similar to that of diverse neurodegenerative diseases. Animal models of neurotoxicity have revealed that clinical symptoms and brain lesions can recover over time via neuroregenerative processes. Specifically, brain-derived neurotropic factor (BDNF) and gamma aminobutyric acid (GABA)-ergic transmission are related to both neurodegeneration and neuroregeneration. This review summarizes the accumulating evidences that suggest a pathogenic role of BDNF and GABAergic transmission, their underlying mechanisms, and the relationship between BDNF and GABA in neurodegeneration and neuroregeneration. This review will provide a comprehensive overview of the underlying mechanisms of neuroregeneration that may help in developing potential strategies for pharmacotherapeutic approaches to treat neurotoxicity and neurodegenerative disease. PMID- 29171443 TI - Risk factors for tuberculosis and beyond. PMID- 29171444 TI - Role of Vitamins B, C, and D in the fight against tuberculosis. AB - Worldwide, tuberculosis (TB) is still a serious and significant health concern, more so with the emergence of multidrug-resistant-TB. The inability of mankind to control this infection stems from the fact that the vaccines and drugs that were once effective against TB are no longer efficacious. This has led to a search for new antituberculous agents and adjuvant therapy. Vitamins are being revisited for their role in pathogenicity as well as for their antimycobacterial properties. Vitamins such as biotin and thiamin are essential for Mycobacterium tuberculosis and are required for establishment of infection. On the other hand, vitamins such as Vitamin C and Vitamin D have been shown to possess antimycobacterial properties. To combat M. tuberculosis, innovative strategies need to be devised, keeping in mind the efficacy of the agent to be used. Vitamins can prove to be useful agents capable of modifying the life cycle and biology of M. tuberculosis. We present here a brief overview of the available knowledge on thiamin, biotin, Vitamin C, and Vitamin D, keeping TB treatment and control in perspective. PMID- 29171445 TI - The epidemiology of tuberculous dactylitis: A case report and review of literature. AB - The literature on tuberculous dactylitis is poor, and most literature consists of isolated case reports. The aim of this case series is to study the particularities and the epidemiological aspects of tuberculous dactylitis in Tunisian patients. Google and Medline search was done using key words "tuberculous dactylitis" and "spina ventosa." Only Tunisian reports in adult patients were included. Eleven cases including this mentioned case were included in this review. There was a female predominance, high frequency of trauma before disease installation, rarity of predisposing factors, and less inflammation in blood tests when comparing with other cases in literature. PMID- 29171446 TI - Do infections with disseminated Mycobacterium avium complex precede sweet's syndrome? A case report and literature review. AB - Sweet's syndrome is reportedly associated with preceding nontuberculous mycobacterial infections (NTMIs). Here, we report on a systemic Mycobacterium intracellulare infection in a patient on corticoid therapy for Sweet's syndrome. Literature searches show that 69.1% of patients with Sweet's syndrome and NTMIs developed this syndrome later than NTMIs and 89.3% of them developed during the clinical course of a rapidly growing mycobacterial infection. The residual cases were associated with slow-growing mycobacteria (14.3%), but only three cases of Mycobacterium avium complex (MAC) infections before the onset of Sweet's syndrome have been reported, and all of them were caused by disseminated MAC disease. One of these cases developed during corticoid therapy for Sweet's syndrome, while another case had underlying diabetes mellitus. Hence, the occurrence of systemic MAC disease may be an inevitable consequence of long-term steroid use and underlying diseases. Literature searches also show that cervical lymphadenitis was a predominant symptom in NTMIs (90.5%). The present case did not have cervical lymphadenitis although the previously reported MAC cases did experience it. Therefore, lymphadenitis from NTMIs may be related to the pathogenesis of Sweet's syndrome. Hence, should a patient have systemic infection without lymphadenitis, it will be more difficult to clinically confirm that MAC disease is a predisposing factor for Sweet's syndrome. PMID- 29171447 TI - Nontuberculous mycobacteria in a tertiary Hospital in Portugal: A clinical review. AB - BACKGROUND: Nontuberculous mycobacteria (NTM) form a heterogeneous group regarding their ability to cause disease. To further understand their clinical relevance, the characteristics of patients who had positive cultures for NTM at a tertiary hospital in Portugal were reviewed. METHODS: Retrospective analysis of patients assessed at the Infectious Diseases (ID) Department of the Sao Joao Hospital Center, from January 2007 to December 2014, from whom at least one biological sample was tested culture positive for NTM. RESULTS: A total of 74 patients with at least one positive culture for NTM were identified. Forty-nine (66.2%) were infected by the human immunodeficiency virus, 4 (5.4%) had cancer, and 7 (9.5%) were under immunosuppressive medication. A total of 13 patients (17.6%) fulfilled the American Thoracic Society/ID Society of America criteria for pulmonary NTM disease and treatment was initiated in 12 other patients (16.2%), all of which were immunocompromised. Mycobacterium avium complex was more frequently associated with disease, responsible for 56% of the patients treated. Patients were treated with antituberculosis drugs adjusted for the species isolated, and cure was achieved in 13 patients (52%). CONCLUSION: The present study highlights the importance of understanding the epidemiology of NTM to better comprehend their clinical impact. PMID- 29171448 TI - Vitamin D, cell death pathways, and tuberculosis. AB - BACKGROUND: Mycobacterium tuberculosis induces cellular necrosis that could promote spread of infection. The aim of this study is to analyze the effects of Vitamin D3 supplementation to improve the effectiveness of 2nd-line anti tuberculosis (TB) drug therapy, especially in relation with cell death pathways. METHODS: Mus musculus C3HeB/FeJ was randomly divided into four groups containing eight animals each. The 1st group (G1), consisting of mice that were intratracheally infected with multidrug-resistant strain of M. tuberculosis and sacrificed on 2-week postinfection to confirm successful infection. (G2) was a group of TB mice without therapy. Then, (G3) was a group of mice with the 2nd line anti-TB therapy. The last group (G4) was a group of mice receiving not only the 2nd-line anti-TB therapy but also daily oral Vitamin D3 supplementation. Immunohistochemistry was used to measure expression of nuclear Vitamin D receptor, apoptosis marker cleaved caspase-3, cathelin-related antimicrobial peptide (CRAMP) and LC3B autophagy markers, necrosis marker RIPK3, and collagenase matrix metalloproteinase-1 (MMP1). The number of bacteria in the lung was calculated by colony forming units. The partial least square structural equation modeling with SmartPLS 3.2.6 software was used to analyze structural models among the variables. RESULTS: Supplementation of Vitamin D3 on the 2nd line anti-TB therapy increases Vitamin D3 receptor, CRAMP, LC3B, caspase-3 (P = 0.026, P = 0.000, P= 0.001), presses MMP1, and the number of bacteria (P = 0.010 and P= 0.000, respectively). The structural equation modeling analysis shows that increasing autophagy pathways reduces necrosis by lowering MMP1, whereas apoptosis reduces necrosis by decreasing the number of bacteria (each with indirect effects - 0.543 and - 0.544). CONCLUSION: A comprehensive analysis with the partial least square structural equation modeling shows decreasing necrosis requires increasing autophagy and apoptosis. PMID- 29171449 TI - Risk factors for tuberculosis mortality in a tertiary care center in Oman, 2006 2016. AB - BACKGROUND: Mortality from tuberculosis (TB) remains high despite its declining global incidence. Host risk factors of TB death have not been fully identified. The aim of this study is to explore some of the host risk factors associated with TB mortality. METHODS: We conducted a retrospective cross-sectional review of patients with TB admitted to Sultan Qaboos University Hospital in Oman from July 2006 to February 2016. Multivariate logistic regression analyses were used to evaluate the risk factors for TB mortality. RESULTS: Of the 205 TB cases reviewed, we identified 31 (15%) TB deaths during TB treatment. The median time of death from starting TB drugs was 30 days. Fifty-one percent of the TB deaths occurred in the 1st month of TB diagnosis. The main risk factors for TB mortality were advanced age, low body weight, negative sputum TB smear, pulmonary involvement, human immunodeficiency virus infection, and noncitizen status. CONCLUSION: To improve TB outcome in this high-risk group, abrupt clinical management approaches should be applied when TB is suspected. Public health measures that increase community awareness of TB mortality and reduce barriers to TB care are crucial to reducing TB mortality. PMID- 29171450 TI - Treatment outcome of tuberculosis patients under directly observed treatment short course and its determinants in Shangla, Khyber-Pakhtunkhwa, Pakistan: A retrospective study. AB - BACKGROUND: Tuberculosis (TB) is one of the leading causes of morbidity and mortality in Pakistan. Assessment of TB treatment outcomes, monitoring and evaluation of its risk factors in Directly Observed Treatment Short Course (DOTS) are among the major indicators of the performance of a national TB control program. Even though Pakistan ranks 5th among the 22 high-TB burden countries, there are no available data in this regard. METHODS: Institution-based retrospective study was conducted to determine the treatment outcome of TB patients and investigate associated risk factors at District Head Quarter Hospital Shangla, Khyber-Pakhtunkhwa, Pakistan. Two-year record (January 2011 to December 2012) of TB clinic of the hospital was reviewed. A total of 493 patients' complete information was reviewed in the study period. RESULTS: Of these, 42.19% were smear-positive pulmonary TB (PTB), 35.09% were smear-negative PTB, and 22.72% were extra-PTB (EPTB). The overall prevalence of smear-positive PTB was 42.19% (95% confidence interval [CI]: 37.9-46.2). Records of the treatment outcome showed that 192 (38.94%) were cured, 276 (55.98%) completed treatment, 13 (2.6%) defaulted, 9 (1.8%) died, 1 (0.2%) treatment failure, and 1 (0.2%) had transferred to other facilities. The overall mean treatment success rate of the TB patients was 94.93%. TB age and TB form or baseline smear were significantly associated with unsuccessful treatment outcome. The risk of unsuccessful outcome was significantly lower among TB patients age Conclusion: The treatment success rate was high and match the World Health Organization criteria. To sustain the effective implementation of DOTS in the area, effective management, and diagnosis should be given for EPTB. PMID- 29171451 TI - Sequence homology and expression profile of genes associated with DNA repair pathways in Mycobacterium leprae. AB - BACKGROUND: Survival of Mycobacterium leprae, the causative bacteria for leprosy, in the human host is dependent to an extent on the ways in which its genome integrity is retained. DNA repair mechanisms protect bacterial DNA from damage induced by various stress factors. The current study is aimed at understanding the sequence and functional annotation of DNA repair genes in M. leprae. METHODS: T he genome of M. leprae was annotated using sequence alignment tools to identify DNA repair genes that have homologs in Mycobacterium tuberculosis and Escherichia coli. A set of 96 genes known to be involved in DNA repair mechanisms in E. coli and Mycobacteriaceae were chosen as a reference. Among these, 61 were identified in M. leprae based on sequence similarity and domain architecture. The 61 were classified into 36 characterized gene products (59%), 11 hypothetical proteins (18%), and 14 pseudogenes (23%). All these genes have homologs in M. tuberculosis and 49 (80.32%) in E. coli. A set of 12 genes which are absent in E. coli were present in M. leprae and in Mycobacteriaceae. These 61 genes were further investigated for their expression profiles in the whole transcriptome microarray data of M. leprae which was obtained from the signal intensities of 60bp probes, tiling the entire genome with 10bp overlaps. RESULTS: It was noted that transcripts corresponding to all the 61 genes were identified in the transcriptome data with varying expression levels ranging from 0.18 to 2.47 fold (normalized with 16SrRNA). The mRNA expression levels of a representative set of seven genes ( four annotated and three hypothetical protein coding genes) were analyzed using quantitative Polymerase Chain Reaction (qPCR) assays with RNA extracted from skin biopsies of 10 newly diagnosed, untreated leprosy cases. It was noted that RNA expression levels were higher for genes involved in homologous recombination whereas the genes with a low level of expression are involved in the direct repair pathway. CONCLUSION: This study provided preliminary information on the potential DNA repair pathways that are extant in M. leprae and the associated genes. PMID- 29171453 TI - Antibiotic resistance in Mycobacterium Abscessus and Mycobacterium Fortuitum isolates from Malaysian patients. AB - BACKGROUND: Rapidly growing mycobacterial species (RGM) are increasingly being recognized as the cause of various superficial and deep infections in humans. Two of the species most frequently isolated from clinical specimens are Mycobacterium abscessus and Mycobacterium fortuitum. Both species are associated with antibiotic resistances that may complicate therapy. This paper describes the pattern of resistance to five antibiotics commonly prescribed for RGM infections, in M. abscessus and M. fortuitum isolated from Malaysian patients. METHODS: The bacterial strains studied were examined with Etest strips to determine their minimum inhibitory concentrations (MICs) toward amikacin, ciprofloxacin, clarithromycin, imipenem, and linezolid. RESULTS: Among 51 M. abscessus isolates examined by the Etest, the overall MICs of ciprofloxacin, imipenem, amikacin, clarithromycin, and linezolid showed resistance rates of 33.3%, 31.4%, 2.0%, 5.9%, and 21.6%, to the five antibiotics, respectively. M. abscessus subspecies abscessus was more resistant than M. abscessus subsp. massilience to ciprofloxacin, imipenem, and linezolid but was more susceptible to clarithromycin and amikacin. M. fortuitum isolates were significantly less resistant than M. abscessus to ciprofloxacin (3.6%) and imipenem (7.1%) but more resistant to clarithromycin (42.9%) and linezolid (39.3%). CONCLUSION: A suitable combination therapy for Malaysian patients would be amikacin plus clarithromycin and ciprofloxacin, to cover infections by all three M. abscessus subspecies and M. fortuitum. PMID- 29171452 TI - The most frequent Mycobacterium tuberculosis complex families in mali (2006-2016) based on spoligotyping. AB - BACKGROUND: To identify strains of Mycobacterium tuberculosis complex (MTBc) circulating in Bamako region during the past 10 years. METHODS: From 2006 to 2016, we conducted a cross-sectional study to identify with spoligotyping, clinical isolates from tuberculosis (TB)-infected patients at different stages of their treatments in Bamako, Mali. RESULTS: Among the 904 suspected TB patients included in the study and thereafter tested in our BSL-3 laboratory, 492 (54.4%) had MTBc and therefore underwent spoligotyping. Overall, three subspecies, i.e., MTB T1 (31.9%) and MTB LAM10 (15.3%) from lineage 4 and M. africanum 2 (16.8%) from lineage 6 were the leading causes of TB in Bamako region during the past 10 years. Other spoligotypes such as MTB T3, MTB Haarlem 2, MTB EAI3, and MTB family 33 were also commonly seen from 2010 to 2016. CONCLUSION: This study showed a high genetic diversity of strains isolated in Bamako region and highlights that M. tuberculosis T1 strain was the most prevalent. Furthermore, the data indicate an increasing proportion of primary drug resistance overtime in Bamako. PMID- 29171454 TI - Nontuberculous mycobacteria in clinical samples with negative acid-fast bacilli. AB - BACKGROUND: There is a progressive increase in nontuberculous mycobacteria (NTM) in pulmonary and extrapulmonary infections that might cause confusion with the Mycobacterium tuberculosis complex. To determine the frequency of finding NTM in clinical samples from patients diagnosed with active tuberculosis, with negative acid-alcohol-resistant bacilli (acid-fast bacillus [AFB]) in a third-level specialty hospital's mycobacterial laboratory between January 2013 and December 2014. METHODS: This is a prospective, descriptive study where isolated strains of biological material were studied in Lowenstein-Jensen and BACTEC MGIT 960 cultures. RESULTS: Clinical samples of 120 patients were studied, with pulmonary samples of 99/120 (82%) and extrapulmonary samples of 21/120 (18%). We identified NTM in 37/120 samples (30.8%), of which 16 in pulmonary, 13 in genitourinary, 3 in bone marrow, and 5 in various specimens. Mycobacterium avium was isolated in 20 samples, Mycobacterium intracellulare in seven samples, and various other species of NTM in the other 10 samples. CONCLUSION: To establish adequate treatment, we point out the importance of identifying the presence of NTM in the clinical samples of active tuberculosis patients with negative AFB, as possibly becoming confused with M. tuberculosis and which is essential in deciding which treatment is the most adequate. PMID- 29171455 TI - Association between effectiveness of tuberculosis treatment and cytochrome P 4502E1 polymorphism of the patients. AB - CONTEXT: The risk of antituberculosis (TB) drug-induced liver injury could be determined by patients' genotype polymorphism of the xenobiotic-metabolizing enzymes. To find the meaning of cytochrome P-4502E1 (CYP2E1) polymorphism in TB patients. Corresponding of CYP2E1 polymorphism in TB patients with the level of isoniazid and rifampicin as well as for the outcome and toxicity development during inpatient TB treatment. METHODS: CYP2E1 genotype was detected with the help of polymerase chain reaction and endonuclease analysis. The level of rifampicin, isoniazid, diene conjugates (DC), and catalase activity in the blood was determined spectrophotometrically. We have considered medical records at the beginning and at the end of inpatient treatment. STATISTICAL ANALYSIS USED: Kruskal-Wallis, ANOVA, and Chi-square tests were used in this study. RESULTS: The concentration of rifampicin 6 h after its intake was 17.6% higher in carriers of slow metabolizer (SM) CYP2E1 genotype than in patients with rapid metabolizer (RM) genotype that proved a participation of hepatic enzyme CYP2E1 in metabolism of rifampicin. According to obtained results in TB patients with RM genotype, the indexes of cytolysis (alanine aminotransferase, aspartate aminotransferase) and bile stasis (gamma-glutathione transferase) were higher comparatively to SM genotype both before and after inpatient treatment. This correlated with a higher concentration of DC in the blood (+8.6%) and lower plasma catalase activity ( 50.0%) in the patients with RM genotype comparatively with the patients with SM genotypes. CONCLUSION: Polymorphism of CYP2E1 genotype is an important criterion for the development of hepatotoxicity before and during TB treatment while increased rifampicin level has no influence on it. PMID- 29171456 TI - Mycobacterium Interjectum isolated from an immunocompetent host with lung infection. AB - Improved molecular diagnostic techniques have resulted in increased reporting of nontuberculous mycobacterial infections. A 40-year-old male immunocompetent individual presented with cough and fever of 2-week duration. His chest X-ray showed cavities in the left upper zone and fibrosis in the right upper zone. His sputum was positive for AFB on Ziehl-Neelsen staining and showed slow-growing mycobacteria in mycobacteria growth indicator tube. The isolate was identified as Mycobacterium interjectum using GenoType(r) Mycobacterium CM assay (Hain Lifescience, GmBH, Nehren, Germany). At the end of a year's treatment, this first case from India has shown good progress. PMID- 29171457 TI - Tubercular colitis masquerading as ischemic colitis: An unusual presentation. AB - Tuberculosis is a common clinical problem which can involve virtually any organ and mimic a multitude of clinical conditions. Colonic tuberculosis is a type of intestinal tuberculosis which involves the colon and mimics inflammatory bowel disease. Occasionally, it is also confused with colonic malignancy. We report the case of a young female who presented with abdominal pain, bleeding per rectum. Abdominal X-ray showed evidence of thumb-printing. A possibility of ischemic colitis was entertained. However, further investigation unraveled the presence of tubercular colitis. The patient improved with anti-tubercular therapy. Colonic tuberculosis can mimic a number of clinical entities and should be considered in differential diagnosis of colonic lesions in endemic areas. PMID- 29171458 TI - Symmetrical peripheral gangrene and tuberculosis: A rare kinship. AB - Symmetrical peripheral gangrene (SPG) is a rare clinical syndrome characterized by ischemic necrosis of 2 or more limbs, without involvement of large vessels. It is often associated with disseminated intravascular coagulation and septic shock. Usually caused by Gram-positive and Gram-negative organisms, tuberculosis as a cause is extremely rare. We present the case of a 46-year-old man, who initially presented with signs and symptoms suggestive of tuberculosis but later developed SPG along with septic shock after his initial visit. The case highlights the progression of this dreaded complication and touches upon recent developments in its etiology as well as pathogenesis. PMID- 29171459 TI - Bilateral inguinal lymphadenopathy presenting as tuberculosis in a case of carcinoma rectum. AB - Isolated bilateral inguinal tubercular lymphadenitis is a very rare presentation. A 59-year-old male, on treatment for Carcinoma rectum (T3 N1 M0) presented with bilateral inguinal lymphadenopathy. Metastasis and tuberculosis were considered for differentials. FNAC of the lesion showed Necrotizing granulomatous lymphadenitis. There was regression of the lesion on both sides after two months of Anti-tubercular Therapy. Even though Metastasis is the commonest cause of inguinal lymphadenopathy in a case of carcinoma rectum, Tuberculosis needs to be considered in the differential diagnosis in our country. FNAC/Biopsy can be considered in those patients to confirm the diagnosis. PMID- 29171460 TI - Knowledge on tuberculosis in rural Myanmar.

Factors associated with their authorisation.] AB - OBJECTIVE: Postauthorisation observational studies are crucial source of information on drug effectiveness and safety. The objectives of this work were to describe the characteristics of the postauthorisation observational prospective studies (EPA-SP) for which authorisation was requested in the Valencian region, as well as to explore which factors influenced the aforementioned authorisation. METHODS: We performed a retrospective analytical study comprising all the EPA-SP for which authorisation was requested in the Valencian region between 2010 and 2015.The variables associated to the studies (e.g., objectives, studied drug, target disease) as well as those concerning the authorisation process itself (e.g., authorisation status, reason for authorisation refusal, current status of the study) were obtained from relevant databases. The analysis was divided into descriptive and analytical stages. RESULTS: We included a total of 249 studies, out of which 192 (77, 1%) aimed at estimating effectiveness or quality of life. The most frequent types of drugs involved in the studies were the antineoplastic and immunomodulating agents (42%). Only 57% of the studies were granted authorisation, with prescription induction and unusual practice being the most common causes for refusal (40.1% and 39.3%, respectively). The authorisation was linked to the diagnosis (circulatory system OR 10,7, IC95% 2,3 to 49,1), ATC L group (OR 4,2, IC95% 1,9 to 49,1) as well as to whether it had been advocated by the industry (OR 0,5, IC95% 0,3 to 0,9). CONCLUSIONS: Given the importance of having information on effectiveness and safety in usual practice, it is a priority for EPA-SP to be directed towards these aims and to promote independent research.

However, the question remains whether there are ways to achieve not only satisfactory glycemic control, but also T2DM remission (or even complete cure). The review presents an update on the concept of T2DM remission and describes the ways of its possible achievement with non-drug and drug treatments and surgery. The mechanisms of T2DM remission are given. PMID- 29171464 TI - [Impact of various wound dressings on wound bed neoangiogenesis in patients with different forms of diabetic foot syndrome]. AB - AIM: To investigate the impact of various wound dressings on wound bed neoangiogenesis in patients with different forms of diabetic foot syndrome (DFS). SUBJECTS AND METHODS: The clinical (local tissue oxygenation) and immunohistochemical (CD31) markers of foot soft tissue neoangiogenesis were evaluated in patients with DFS receiving negative pressure (NP) therapy and collagen-containing dressings (CCDs) versus standard treatment. 63 patients with neuropathic and neuroischemic (without critical ischemia) forms of DFS were examined after wound debridement. In the postoperative period, 21 patients received NP treatment, CCDs were applied to 21 patients, and 21 patients had standard treatment. RESULTS: During NP therapy, there was statistically significantly intensified local microhemodynamics, as evidenced by transcutaneous oximetry (p < 0.05); the remaining two groups showed no statistically significant differences in transcutaneous oxygen tension during the treatment. Immunohistochemical examination revealed a significant increase in the number of newly formed vessels, as shown by anti-CD31 antibody staining (p < 0.05), in patients who had NP therapy and CCDs (p < 0.05). CONCLUSION: Vacuum (NP) therapy versus standard therapy most effectively affects wound bed neoangiogenesis. This is reflected in the increased local tissue microhemodynamics, as confirmed by immunohistochemical examination. PMID- 29171465 TI - [A 20-year prospective follow-up study to evaluate the development of retinopathy and nephropathy after the onset of type 1 diabetes mellitus: Contribution of glycemic control and metabolic memory]. AB - AIM: To assess the time course of changes in the level of glycated hemoglobin (HbA1c) for 20 years after the onset of type 1 diabetes mellitus (T1DM) and to compare its correlation with the development of microvascular complications, such as diabetic retinopathy (DR) and diabetic nephropathy (DN). SUBJECTS AND METHODS: A total of 187 children with new-onset T1DM were registered in Moscow in 1994. During the 20-year follow-up study, these patients underwent regular check-ups at the Endocrinology Research Center, Ministry of Health of the Russian Federation, which included assessment of physical data, HbA1c 2-4 times a year, biochemical blood and albuminuria tests (once per year), and ophthalmologic examination (twice a year). A total of 155 people fully completed the 20-years follow-up study. RESULTS: During the 20-year follow-up period after the onset of T1DM, 86 of the 155 patients developed microvascular complications: DR and DN in 86 (55.5%) and 24 (15.5%) cases, respectively; while DR concurrent with DN were noted in 20 patients. By the time of their last visit, 69 (44.5%) patients had no evidence suggesting the presence of microvascular complications. The level of HbA1c at the onset of the disease in patients who later developed the complications was higher than in those without complications (10.2+/-0.6 and 8.5+/-0.2%, respectively (p = 0.003). The statistically significant differences in HbA1c levels between the groups persisted during subsequent 15 years of follow up, averaging 9.2+/-1.5, 9.7+/-0.9, and 8.1+/-0.7% after 5, 10, and 15 years, respectively, in the complication group and 7.1+/-0.3, 8.1+/-0.4, and 7.2+/-0.2% in the non-complication group (p < 0.01). Over the last 5 years of the follow-up, the mean HbA1c level between the groups was not significantly different, which at the end of the 20-year follow-up period was 7.8+/-0.3 and 7.4+/-0.6%, respectively (p > 0.05). The mean duration of T1DM, in which DR developed, was 9.6+/-6.2, 11.0+/-2.0, and 13.6+/-4.6 years for the non-proliferative, pre proliferative, and proliferative stages, respectively. That of T1DM, in which DN developed, was 11.8+/-0.6 years for microalbuminuria and 16.1+/-1.3 years for macroalbuminuria. CONCLUSION: The 20-year clinical follow-up of patients who had fallen ill with T1DM in childhood showed that diabetic microangiopathies developed with the long-term preservation of poor blood glucose control (BGC) starting at the onset of the disease. At the same time, the complications progressed to more severe stages, despite a clear trend toward better BGC. This may be suggestive of the negative metabolic memory phenomenon, which necessitates stable BGC, starting at the onset of the disease, for the prevention of microvascular complications. PMID- 29171466 TI - [The attitude of patients with types 1 and 2 diabetes mellitus towards having the disease]. AB - AIM: To analyze the types of attitude towards disease, their relationships to its course in patients with diabetes mellitus (DM). SUBJECTS AND METHODS: 418 patients with DM, including 318 with type 2 DM (T2DM) and 100 with Type 1 (T1DM), were examined. Clinical and laboratory examinations were performed; the types of attitude towards the disease were studied. RESULTS: The patients with T2DM were more frequently found to have anxious (12.9%) and hypochondriacal (10.7%) types of attitude towards the disease; those with T1DM had euphoric types. The paranoiac type of disease attitude, which was characterized by the presence of peculiar notions about the disease, was detected in 15.1% of the patients with T2DM and in 13% of those with T1DM. Hypernosognosia (overreaction to disease) was more often identified in T2DM (62.3% versus 39% in T1DM (chi2; p < 0.001). In the T2DM group, hypernosognosia was more frequently seen in women, unemployed persons, and obese patients. With the comparable awareness about the disease and degree of self-control, the patients with T2DM with no signs of hypernosognosia had a lower glycated hemoglobin level [7.35 (6.6; 8.6)%] than those with hypernosognosia [7.9 (7; 9.4)%] (p = 0.024). CONCLUSION: The revealed peculiarities of attitude towards the disease in patients with DM justify the need for increased attention to their psychological characteristics. The situation could be improved if the physicians are be informed, the time of outpatient care is prolonged, and psychotherapists and/or clinical psychologists are widely involved in the management of diabetic patients.

SUBJECTS AND METHODS: A total of 196 patients with T2DM were examined and divided into 2 groups: 1) 52 patients (40.4% of men) aged 52.8+/-8.7 years with compensated T2DM (glycated hemoglobin (HbA1s), 6.3+/-0.5%); 2) 68 patients (38.2% of men) aged 52.8+/-8.1 years with decompensated T2DM (HbA1s, 9.4+/-1.7%). Both patient groups had concomitant hypertension (its prevalence, degree, stage of hypertension were comparable). A control group consisted of 76 volunteers (40.8% of men) aged 52.2+/-8.7 years with normal carbohydrate metabolism and without signs of cardiovascular disease (HbA1s, 5.3+/-0.49%). Capillary blood flow in the finger nail-fold area was investigated in all the participants. A digital optical capillaroscope with image processing software was used to obtain quantitative blood microcirculatory parameters. The diameters of arterial and venous capillary segments were measured, by calculating the remodeling rate. The degree of capillary tortuosity, network density, and polymorphism and the size of the perivascular zone (PZ) were estimated. Blood rheological properties and capillary blood flow velocity were also investigated. RESULTS: The decompensated T2DM group compared to the compensated T2DM group was found to have a narrowing of the arterial capillary segment diameter (8.4+/-2.0 um; p=0.009) and an increase in remodeling rates (1.47+/-0.22; p=0.000). The tendency of the PZ size to be larger in patients with decompensated T2DM compared to those with compensated T2DM (p=0.080) and the increase in this indicator compared to the control group (p=0.001) reflect the presence of edema syndrome in Group 2, as laboratory confirmed by a statistically significantly elevated sodium level (p=0.000; p=0.006). The enlarged venous capillary segment demonstrates involvement of the venous component in microcirculatory disorders in T2DM. The reduction in the density of the capillary network and the increase in capillary tortuosity and polymorphism, which were also observed in the patients of both groups versus the control group, are referred to as disorders that are characteristic of T2DM. CONCLUSION: In decompensated T2DM, capillary bed structural and functional changes are found as a narrowing of the arterial capillary segment, an increase in the rate of remodeling, and enlargement of the PZ. Digital capillaroscopy opens up new possibilities for assessing the magnitude of changes in the microcirculatory system in DM and can simultaneously evaluate the efficiency of treatment, by monitoring the status of the microvasculature. PMID- 29171468 TI - [Glycemic variability and oxidative stress in patients with type 2 diabetes mellitus during combined glucose-lowering therapy]. AB - AIM: To evaluate the impact of intensified glucose-lowering therapy on carbohydrate metabolic indicator, such as glycated hemoglobin, fasting blood glucose level (BGL) (FBGL), postprandial BGL (PBGL), and glycemic variability (GV) in patients with type 2 diabetes mellitus (T2DM) during metformin monotherapy before and 3 months after therapy intensification. SUBJECTS AND METHODS: The investigation enrolled 51 patients with T2DM treated with metformin 1000 mg twice daily, who failed to achieve satisfactory glycemic control. During randomization, the treatment was intensified by addition of sitagliptin 100 mg/day in Group 1 (n=25) or gliclazide MB 60 mg/day in Group 2 (n=26). Before and 3 months after the treatment, carbohydrate metabolic indicators were investigated, 24-hour BGL monitoring (continuous glucose monitoring system (GMS)) was performed, and the body's antioxidant status was examined by determining the total antioxidant capacity of blood plasma (overall sound pressure levels (OASPL)). RESULTS: During 3-month treatment, Group 1 had a significantly reduced FBGL compared to that before the therapy; in Group 2 this index did not change significantly. Both study groups showed a significant decrease in PBGL and glycated hemoglobin (HbA1c). The mean amplitude of glycemic excursion (MAGE) was significantly decreased in the sitagliptin intensification group. In both groups, the standard deviation (SD) reduced significantly by 26% in Group 1 and by 38% in Group 2. Both groups also displayed a significant increase in blood OASPL (p<0.05). CONCLUSION: The addition of sitagliptin significantly affected the change in the indicators of both the standard carbohydrate metabolism (FBGL, PBGL, and HbA1c) and GV (MAGE, SD), whereas that of gliclazide MV altered some studied parameters. OASPL significantly increased in both groups. PMID- 29171469 TI - [Risk of type 2 diabetes mellitus in the Kyrgyz population in the presence of ADIPOQ (G276T), KCNJ11 (Glu23Lys), TCF7L2 (IVS3C>T) gene polymorphisms]. AB - AIM: To analyze the association of genotype combinations of the polymorphic markers G276T in the ADIPOQ gene, Glu23Lys in the KCNJ11 gene, and IVS3C>T in the TCF7L2 gene with the development of type 2 diabetes mellitus (T2DM) in the Kyrgyz population. SUBJECTS AND METHODS: The investigation enrolled 23 Kyrgyz people, of whom there were 114 patients with T2DM and 109 without T2DM (a control group). T2DM was diagnosed in accordance with the WHO criteria (1999). The genotypes of ADIPOQ (G276T), KCNJ11 (Glu23Lys), and TCF7L2 (IVS3C>T) gene polymorphisms were identified using the restriction fragment length polymorphism analysis. RESULTS: When typing at the polymorphic loci G276T in the ADIPOQ gene, Glu23Lys in the KCNJ11 gene, and IVS3C>T in the TCF7L2 gene, the development of T2DM in the Kyrgyz population was associated with the T allele (odds ratio (OR), 1.68; p=0.025), the heterozygous G276T genotype (OR 1,8; p=0.036) in the ADIPOQ gene; the 23Lys allele (OR, 1.62; p=0.019) in the KCNJ11 gene; a two-locus genotype combination in the genes ADIPOQ/KCNJ11: G276T/Glu23Lys (OR, 4.88; p=0.0013), G276G/Lys23Lys (OR, 4.65; p=0.019), G276T/Glu23Glu (OR, 3.10; p=0.022), a two locus genotype combination in the genes ADIPOQ/TCF7L2: G276T/SS (OR, 1.97; p=0.04); two-locus genotype combinations in the genes KCNJ11/TCF7L2: Lys23Lys/CC (OR, 2.65; p=0.042), Glu23Lys/CT (OR, 3.88; p=0.027); and a three-locus genotype combination in the genes ADIPOQ/KCNJ11/TCF7L2: G276T/Glu23Lys/CT (OR, 14.48; p=0.02). CONCLUSION: The development of T2DM in the Kyrgyz population is genetically determined by ADIPOQ (G276T) gene, KCNJ11 (Glu23Lys), and TCF7L (IVS3C>T) gene polymorphisms with the predisposing value of the T allele of the heterozygous G276T genotype in the ADIPOQ gene; the 23Lys allele in the KCNJ1 gene; as well as by genotype combinations in the genes ADIPOQ/KCNJ11 (G276T/Glu23Lys, G276G/Lys23Lys, G276T/Glu23Glu); ADIPOQ/TCF7L2 (G276T/SS); KCNJ11/TCF7L2 (Lys23Lys/CC, Glu23Lys/CT); ADIPOQ/KCNJ11/TCF7L2 (G276T/Glu23Lys /CT). The IVS3C>T locus in the TCF7L2 gene is not independently statistically significantly associated with the development of T2DM; however, its predisposing effect has been identified in its combination with the variant genotypes of the polymorphic loci G276T in the ADIPOQ gene and Glu23Lys in the KCNJ11 gene. PMID- 29171470 TI - [Shereshevsky-Turner syndrome: Estrogen replacement therapy and cardiovascular risk factors]. AB - AIM: To investigate the impact of menopausal hormone therapy (MHT) on the expression of risk factors for cardiovascular events (CVEs) in patients with Shereshevsky-Turner syndrome (STS); to elaborate an algorithm for patient management using MHT. SUBJECTS AND METHODS: From 2010 to 2012, a total of 41 patients aged 14 to 35 years with STS were examined in the framework of a prospective observational study. 100 STS case histories in 2000 to 2009 were retrospectively analyzed. The indicators of the so-called cardiometabolic risk, such as body mass index (BMI), lipidogram readings, venous plasma glucose levels, and blood pressure, were estimated in relation to the type of MHT. In the prospective part of the investigation, an angioscan was used to estimate vessel characteristics (stiffness, wall tone, endothelial function (EF)), by using the examination data. RESULTS: 90% of the patients with STS were found to have risk factors for CVEs: atherogenic dyslipidemia (85%; 51% in the general female population of the same age), diastolic hypertension (36%; no more than 5% that is not typical for age-matched healthy general female population). In addition to increased arterial wall stiffness (AWS), obvious EF disorder is typical for STS patients. MHT was accompanied by a dose-dependent (estradiol, at least 2 mg) reduction in diastolic blood pressure by an average of 13% over 24 months, an increase in high density lipoprotein levels by more than 10% over 24 months and also contributedto a decrease in AWS and an improvement in EF. CONCLUSION: By favorably affecting the EF of vessels and reducing the severity of atherogenic dyslipidemia, MHT potentially enables a reduction in CV risk in patients with STS. PMID- 29171471 TI - [Associations between metabolic syndrome and reduced lung function in young people]. AB - AIM: To reveal possible associations between metabolic syndrome (MS) and reduced lung function. SUBJECTS AND METHODS: In 2013-016, a cross-sectional survey was conducted in 908 Novosibirsk dwellers, which included spirometry to evaluate external respiratory function (ERF). For the detection of MS, the investigators used the 2009 All-Russian Research Society of Cardiologists criteria: waist circumference (WC) > 80 cm for women and >94 cm for men in combination with two of the following criteria: blood pressure (BP) >=130/85 mm Hg, triglycerides (TG) >=1.7 mmol/l, high-density lipoproteins (HDL) cholesterol <1.0 mmol/l for men and <1.2 mmol/l for women, low-density lipoprotein (LDL) cholesterol >3.0 mmol/l, and glucose >=6.1 mmol/l. RESULTS: The mean values of WC were significantly greater with a forced expiratory volume in one second (FEV1) <80% than those with a FEV1 of >=80% in both men (p=0.002) and women (p=0.050); in women, the mean values of WS were higher than those with a FEV1/forced vital capacity (FVC) <70% than those with a FEV1/FVC of >=70% (p=0.047); the mean systolic and diastolic BP levels were significantly more with reductions in FEV1 and FVC, and the level of HDL cholesterol was significantly lower than that with a FEV1 of < 80% in men only. Significant correlations were found between FEV1 and all components of MS in men, between the majority of components of MS and FVC in men, between WC, BP, and FEV1/FVC in men and women, between plasma glucose levels and FEV1/FVC in women. Linear regression analysis revealed significant inverse correlations of FEV1 with TG, glucose, BP; those of FVC with TG, glucose; at the same time a positive association with HDL cholesterol in men, and only a negative correlation of FEV1/FVC with WC. CONCLUSION: The revealed associations between MS and reduced lung function can most likely be explained by the greater prevalence of both MS and its components (hypertension, hypertriglyceridemia, hyperglycemia, LDL hypercholesterolemia) among Novosibirsk men. This is consistent with the assertion that the decline in ERF, particularly FEV1, may be a marker of future cardiovascular disease morbidity and mortality. PMID- 29171472 TI - [CYP7A1 gene polymorphism and the characteristics of dyslipidemias in patients with nonalcoholic fatty liver disease concurrent with hypothyroidism]. AB - AIM: To investigate the association of the polymorphic variants -204A > C (rs 3808607) in the CYP7A1 gene with the development of dyslipidemias in healthy individuals, in patients with non-alcoholic fatty liver disease (NAFLD) and in those with NAFLD concurrent with hypothyroidism. SUBJECTS AND METHODS: DNA samples and lipidograms were examined in 180 patients, including 60 healthy individuals (Group 1), 60 patients with hypothyroidism concurrent with NAFLD (Group 2), and 60 patients with NAFLD (Group 3). All the patients underwent ultrasound examination of the thyroid gland and abdominal cavity organs; FibroMax scores were calculated. RESULTS: All the study groups most frequently showed a homozygous AA genotype (86.6% of cases in Group 1, 80% in Group 2, and 83.3% in Group 3). The development of NAFLD in CC genotype carriers is characterized by the most pronounced changes in lipid metabolism (atherogenic index (AI), 7.32 in Group 3) compared to the genotypes AA (AI, 4.56 in Group 2 and 1.73 in Group 1) and CC (AI, 6.43 in Group 2 and 2.52 in Group 1) in functional insufficiency of thyroid hormones and relative normal conditions. CONCLUSION: The analysis of the relationship of polymorphic variants CYP7A1 rs 38088607 to lipid metabolic disturbances in the study groups showed that the significantly higher levels of atherogenic cholesterol fractions were determined in the CC genotype compared to AA genotype carriers and they did not depend on the presence of NAFLD and hypothyroidism. The findings make it possible to consider the AA homozygous genotype of variant mutation CYP7A1 rs 38088607 as protective against dyslipidemia. However, in functional insufficiency of thyroid hormones, the level of triglycerides is significantly higher in both genotypes, which suggests that hypothyroidism plays an essential role in the development of dyslipidemia and NAFLD. PMID- 29171473 TI - [Time course of changes in cytokines (IFN-gamma, IFN-alpha, IL-18, TNF-alpha) in the treatment of moderate influenza A (H1N1) pdm09 (2013-2016) with oseltamivir (Tamiflu) and umifenovir (Arbidol) alone and in combination with Kagocel]. AB - AIM: To assess correlation of cytokines levels and therapy regimes a relationship of the time course of changes in the cytokines IFN-gamma, IFN-alpha, IL-18, and TNF-alpha to the treatment option for influenza A (H1N1) pdm09 with umifenovir (Arbidol) 800 mg/day for 5 days (n=50); oseltamivir (Tamiflu) 150 mg/day for 5 days (n=50); umifenovir (Arbidol) 800 mg/day for 5 days in combination with Kagocel 72 mg/day for 2 days.; 36 mg/day for 2 days (n=50); oseltamivir (Tamiflu) (150 mg/day for 5 days) in combination with Kagocel 72 mg/day for 2 days; 36 mg/day for 2 days (n=50). A comparison group consisted of 30 healthy volunteers. MATERIAL AND METHODS: The state of immunologic reactivity was assessed twice: at admission of the patients to an infectious disease clinic (at 1-3 disease days) and in the early convalescent period (at 7-8 disease days): venous blood samples were collected to determine the concentrations of IFN-gamma, IFN-alpha, IL-18, and TNF-alpha by a solid-phase enzyme immunoassay. RESULTS: All the patients in the acute phase of influenza A showed a statistically significant increase in the levels of IFN-gamma, IFN-alpha, and IL-18 as compared with the control group. The groups receiving monotherapy in the early convalescent period had a decrease in the IFN-gamma, IFN-alpha, and IL-18 concentrations that could be compensated by the combined use of the immunomodulator Kagocel. No statistically significant changes in the levels of TNF-alpha were found in the patients of all the groups, but the groups receiving monotherapy exhibited its lower concentrations in the convalescence period. CONCLUSION: The combination of etiotropic antiviral drugs with Kagocel enhances the efficiency of antiviral therapy. Monitoring of antiviral cytokines during the treatment of influenza A is a convenient tool to verify the efficiency of antiviral therapy and needs to be more widely introduced into medical practice. PMID- 29171474 TI - [Progressive pulmonary hypertension in a patient with type 1 Gaucher disease]. AB - Gaucher disease is the most common form of hereditary enzymopathies combined into a group of lysosomal storage diseases. The basis for the disease is a hereditary deficiency of the activity of acid beta-glucosidase, a lysosomal enzyme involved in the catabolism of lipids, which results in the accumulation of nonutilized cellular metabolism products in the macrophage lysosomes. The main clinical manifestations of type 1 Gaucher disease are cytopenia, hepatomegaly, and splenomegaly, and bone lesion. One of the atypical clinical manifestations of Gaucher disease is damage to the lungs with the development of pulmonary hypertension, which is usually considered within the underlying disease - the development of pneumosclerosis due to macrophage dysfunction. The paper describes a case of progressive pulmonary hypertension in a patient with type 1 Gaucher disease. PMID- 29171475 TI - [Long-term consequences of polycystic ovary syndrome]. AB - Polycystic ovary syndrome (PCOS) is the most common chronic endocrine disease in women. The prevailing complaints at a young age are menstrual irregularities, infertility, and hyperandrogenism-related problems. However, metabolic disorder induced complications have been in the foreground over years. The review gives the current ideas on a change of clinical manifestations in the natural course of PCOS, as well as the pathogenetically grounded prevention of complications in patients. PMID- 29171476 TI - [Recombinant human parathyroid hormone in the therapy of hypoparathyroidism]. AB - Hypoparathyroidism is an endocrine disease that results from deficiency or complete absence of parathyroid hormone (PTH), a biologically active 84-amino acid polypeptide. Standard therapy for chronic hypoparathyroidism includes oral calcium salts and active vitamin D metabolites and is aimed at maintaining a balance between optimal near-normal serum calcium concentration and normocalcuria. Traditional treatment regimens not always lead to the compensation for calcium and phosphorus metabolism. Until recently, hypoparathyroidism is the only endocrine disorder that has not been treated with the recombinant hormone. To date, two recombinant PTH forms have been synthesized, which can be used as pathogenetic therapy for hypoparathyroidism. This review is dedicated to replacement therapy for hypoparathyroidism, by using both the full-length PTH molecule (1-84) and its shorter, but fully active, PTH form (1-34). This review considers stages in the developmental of hormone replacement therapy for hypoparathyroidism, discusses the most rational dosing regimens, and compares their efficacy and safety, as well as prospects for the development of this area. PMID- 29171477 TI - [Endothelial dysfunction and arterial wall stiffness: New targets in diabetic nephropathy]. AB - In recent years, one of the promising areas in clinical medicine is the study of impaired ments in endothelial function and arterial wall stiffness, which can be referred to as one of the important predictors of cardiovascular events in patients with chronic kidney disease, including that of diabetic etiology. There is strong evidence that endothelial function and great artery stiffness may be used as reliable clinical and instrumental indicators to evaluate the efficiency of therapeutic measures and the rate of progression of cardiovascular disorders in type 2 diabetes mellitus. The article presents data on the role of endothelial dysfunction and arterial wall stiffness in the progression of chronic kidney disease in type 2 diabetes mellitus and discusses the possibility of their correction with pharmacological agents. PMID- 29171478 TI - [Enteral failure and metabolic syndrome: Common neurohormonal mechanisms of development, possibilities of their rational therapy]. AB - The paper deals with small bowel (SB) functional disorders in metabolic syndrome (MS). The main components of a cascade of metabolic abnormalities in MS are closely due to SB functional changes. This is associated to some extent with the presence of common neurohormonal mechanisms in the development of enteropathy and MS. The paper gives the physical, laboratory and instrumental methods for identifying SB dysfunctions in patients with MS. Therapy for the latter is of particular interest in the context of SB functional recovery. The authors discuss the possibilities of enteropathy therapy in patients with MS; thus there is not only SB functional recovery, but also improved overall metabolic processes.

PMID- 29171482 TI - [Sleep quality and hormone levels in the morning and evening hours under chemical pollution]. AB - AIM: To evaluate self-assessment of sleep and the level of hormones in the morning and evening in chemical pollution conditions. MATERIAL AND METHODS: Three hundred adolescent and adult men living in the regions with low and high levels of chemical pollution were examined using questionnaires for self-assessment of quality of sleep, sleep hygiene, daytime sleepiness. Levels of cortisol and testosterone in the saliva were determined in the morning and evening hours by ELISA. RESULTS AND CONCLUSION: In areas with low pollution level, there were normal changes in hormone levels with an increase in the morning and decrease in the evening. In high pollution conditions, the average levels of hormones increased, the morning-evening gradient disappeared. These conditions were also associated with an increase in daytime sleepiness and disturbances in the sleep wake cycle and the endocrine regulation system that indicate the possibility of the development of internal desynchronosis. PMID- 29171483 TI - [Intermittent hypoxia due to sleep apnea syndrome in patients with type 2 diabetes mellitus]. AB - OBJECTIVES: To evaluate the possible association between intermittent hypoxia (IH) and HbA1c in patients with insufficient control type of 2 diabetes mellitus (T2DM). MATERIAL AND METHODS: In this cross-sectional study 183 patients with HbAc1>=7% underwent three-channel overnight monitoring (ApneaLink) and completed Berlin Questionnaire, Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index. Patients were divided in two groups, based on the cut-off value of oxygen desaturation index>=15. RESULTS AND CONCLUSION: There were 79 (43%) patients with intermittent hypoxia, which was associated with poorer glycaemic control, defined as HbA1c>8.7% (sample median) in the univariate analysis and after adjustment for body mass index OR 2,40 (CI 1.21-4.95, p=0.021). Neither of three questionnaires yielded satisfactory results as a screening method in patients with T2DM. There is a need to implement instrumental screening of sleep-disordered breathing in this population and to study the effects of CPAP-therapy on glycaemic control and carbohydrate metabolism. PMID- 29171484 TI - [Sexual functioning and sexual dysfunction in women with infertility]. AB - AIM: To study sexual dysfunction and assess the need in sexological care to improve quality of life of women with infertility. MATERIAL AND METHODS: Sexual functioning was studied in 329 women with infertility and 722 women who underwent an outpatient gynecological examination using a clinical interview and the Female Sexual Function Index (FSFI). RESULTS: In 24.01% of women with infertility, the total FSFI score was correlated with the presence of clinically relevant disorders. Sexual dysfunction was identified in 16.1% of women with infertility including libido disorder (84.9%), dyspareunia (30.2%) and orgasmic dysfunction (13.2%). The latent forms of sexual dysfunction were identified as well. CONCLUSION: The study showed a high need for curative and preventive sexological care to improve quality of life of women with infertility.

AB - AIM: To improve the quality of anesthesia in school-age children by using intraoperative metabolic-mediated cerebroprotection to reduce the incidence of cognitive impairment after total intravenous anesthesia based on propofol. MATERIAL AND METHODS: A randomized, prospective, longitudinal clinical study was conducted, involving 60 school-age children operated under total intravenous anesthesia on the basis of propofol. Children were randomized into two equal groups. Patients of the 1st group did not receive intraoperative metabolic mediated cerebroprotection, patients of the 2nd group were treated with cytoflavin. For Z-assessment of changes in cognitive potential, neuropsychological testing of 30 children of the same age who were not subjected to surgical intervention was performed. RESULTS AND CONCLUSION: On the 1st day of the postoperative period, 13.79% of patients of the 1st group had postoperative cognitive dysfunction (POCD), on the 7th day, POCD was observed in 26.67% of children. In the 2nd group, POCD was detected in 6.67% and 3.33% of patients on the 1st and 7th day, respectively (p=0,009). The results confirm the efficacy of cytoflavin in intraoperative prevention of POCD in school-age children. PMID- 29171486 TI - [Monitoring of neurotrophic factors and cognitive function in patients with traumatic brain injury]. AB - AIM: To study the neurological and cognitive status in comparison to the quantitative content of blood serum neurotrophic factors of patients with acute and long-term brain injury during treatment with cerebrolysin. MATERIAL AND METHODS: Eighty patients, 56 men and 24 women, aged from 18 to 64 years, were examined in acute and long-term periods of the brain injury of moderate severity. An open, comparative, randomized study was performed before and after treatment with cerebrolysin. RESULTS AND CONCLUSION: Cognitive impairment, dysregulation type in the acute and long-term brain injury of mild to moderate severity was associated with the low content of brain-derived neurotrophic factor. These disorders were clinically more pronounced in patients with the damage of the frontal and temporal lobes. After treatment with cerebrolysin, a significant positive dynamics on the scale of frontal dysfunction and increased levels of serum brain-derived neurotrophic factor were identified. PMID- 29171487 TI - [Evaluation of efficiency and safety of adding neuromultivit to basic therapy of vertebrogenic radiculopathy]. AB - AIM: To evaluate the efficacy and safety of neuromultivit (valiant, Russia) as add-on to the basic therapy of vertebrogenic radiculopathy (VR) L5-S1. MATERIAL AND METHODS: The open clinical trial included 100 patients with VR L5-S1 randomized into 2 groups. In group 1, patients received neuromultivit and basic therapy; in group 2 only basic therapy. Treatment efficacy was assessed by the dynamics of regression of pain intensity on the visual analogue scale (VAS), McGill pain questionnaire (MGPQ), Aberdeen back pain scale (ABPS), the Quebec Back Pain Disability Scale (QBPDS), the dynamics of neurologic symptoms, the need for additional treatment with NSAID. Safety was assessed by evaluation of vital functions, laboratory tests, ECG, registration of adverse events (AE). RESULTS: In both groups, a significant positive changes on VAS, MGPQ, ABPS, QBPDS were observed. Nevertheless, the positive effect of therapy was more pronounced in group 1 p<0.05). The AE spectrum between two groups did not differ significantly (p<0.05). CONCLUSION: Addition of neuromultivit to basic therapy increased the efficacy of treatment of VR L5-S1. PMID- 29171488 TI - [The efficacy of recognan in the early stage of ischemic stroke]. AB - AIM: To assess the efficacy and safety of recognan in patients with acute ischemic stroke (IS). MATERIAL AND METHODS: Seventy-nine patients, aged from 30 to 80 years, were examined in the early stage of IS. All patients received recognan (citicoline) in dose of 1000 mg/daily during 15 days. The recovery of cognitive functions (MMSE), level of consciousness (Glasgow Coma Scale), severity of focal neurological deficit (NIHSS) and functional recovery (Rankin scale, Barthel index, Rivermead Mobility Index) were assessed. RESULTS AND CONCLUSION: A decrease of cognitive impairment, improvement of memory, regression of neurological symptoms and increase in the motor activity were observed. Recognan used in dose of 1000 mg/daily during 15 days in the complex treatment of patients with IS promotes the recovery of cognitive function, reduces neurological symptoms and improves the recovery of motor activity. PMID- 29171489 TI - [Melatonin in the treatment of low back pain and predictors of its efficacy]. AB - AIM: To assess analgesic properties of melatonin in the treatment of chronic non specific low back pain and to study predictors of its efficacy. MATERIAL AND METHODS: A study included 178 patients, aged from 40 to 65 years, with chronic non-specific low back pain during >3 month and the VAS score >3. Patients were stratified into 6 groups (3 pairs of comparison). In the first pair, patients of both groups received a combination of 500 mg of glucosamine hydrochloride and 500 mg of chondroitin sulfate; in the second pair - a combination of 500 mg of glucosamine hydrochloride and 500 mg of chondroitin sulfate and diclofenac, in the third pair - diclofenac. All patients received additionally melaxen. The duration of the study was 3 month in the first pair and one month in the second and third pairs. With regard to response to melatonin, patients of the main groups were divided into responders and non-responders. Baseline factors determining the efficacy of treatment with melatonin were studied. RESULTS AND CONCLUSION: A significant reduction in pain intensity at movement and resting state was noted in all main groups compared to comparison groups. This result indicates possible analgesic properties of melatonin. Moreover, factors predicting the efficacy of such therapy were determined. Addition of melatonin to the standard scheme of low back pain treatment increases its efficacy, in particular in case of comorbidity of pain and sleep disorders and depressive symptoms. PMID- 29171490 TI - [Genetic and clinical predictors of treatment efficacy in depressive disorders]. AB - AIM: To study clinical and genetic characteristics that impact on the efficacy of pharmacotherapy of depressive disorders. MATERIAL AND METHODS: The study included 188 patients with unipolar depressive disorders of different genesis (psychogenic, endogenous and organic). A clinical-psychopathological method and depression psychometric scales were used. Serotonin transporter 5-HTTLPR and STin2 and dopamine transporter 3',-VNTR polymorphisms were determined. RESULTS AND CONCLUSION: The S-allele of the 5-HTTLPR polymorphism is associated with the low efficacy of treatment with selective serotonin reuptake inhibitors. Tricyclic antidepressants are more effective in treatment of psychogenic depression. The authors determined clinical factors that can predict response to treatment of psychogenic and endogenous depression. No predictors were found for organic depression. PMID- 29171491 TI - [The efficacy and tolerability of pericyazine in the treatment of patients with schizotypal disorder, organic personality disorders and pathocharacterological changes within personality disorders]. AB - AIM: To assess the efficacy and tolerability of pericyazine in the treatment of patients with mental disorders manifesting with psychopathic-like symptoms and correction of pathocharacterological disorders in patients with personality disorders during the short-term admission to the hospital or the long-term outpatient treatment. MATERIAL AND METHODS: Sixty-three patients with schizotypal personality disorder and organic personality disorder with psychopathic-like symptoms and pathocharacterological changes within the diagnosis of dissocial personality disorder and borderline personality disorder were examined. Patients received pericyazine during the short-term admission to the hospital (6 weeks) or the long-term outpatient treatment (6 month). Efficacy, tolerability and compliance were assessed in the study. RESULTS AND CONCLUSION: Treatment with pricyazine was effective in all patients. The improvement was seen in patients with organic personality disorders and patients with personality disorders (psychopathy). The maximal effect was observed in inpatients and this effect remained during outpatient treatment. The improvement of mental state of patients with schizotypal personality disorder achieved during inpatient treatment with pericyazine continued during the long-term outpatient treatment. Side-effects were restricted to extrapyramidal symptoms, the frequency of metabolic syndrome was low. During outpatient treatment, the compliance was higher if the patient was managed by the same psychiatrist during inpatient- and outpatient treatment.

AB - AIM: To assess brain stem dysfunction in patients with hemodynamically significant stenosis of vertebral arteries (VA) using short latency brainstem auditory evoked potentials (BAEP). MATERIAL AND METHODS: The study group included 50 patients (mean age 64+/-6 years) with hemodynamically significant extracranial VA stenosis. RESULTS: Patients with hemodynamically significant extracranial VA stenosis had BAEP abnormalities including the elongation of interpeak intervals I V and peak V latency as well as the reduction of peak I amplitude. After transluminal balloon angioplasty with stenting of VA stenoses, there was a shortening of peak V latency compared to the preoperative period that reflected the improvement of brain stem conductive functions. CONCLUSION: Atherostenosis of vertebral arteries is characterized by the signs of brain stem dysfunction, predominantly in the pontomesencephal brain stem. After transluminal balloon angioplasty with stenting of VA, the improvement of brain stem conductive functions was observed.

AB - AIM: To highlights the problems of assessing cognitive deficits in schizophrenia, relevant to the epigenetic, as well as a wide range of other approaches to the search for biological bases of cognition. MATERIAL AND METHODS: The literature on the weaknesses in the evaluation of cognitive functions in patients with schizophrenia are summarized and discussed. The analysis is illustrated by our experience in developing a cognitive battery and a sample to examine relationships between DNA methylation in blood cells and cognitive deficits in schizophrenia. RESULTS AND CONCLUSION: It has been shown that to assess cognitive deficits in patients and to reduce the influence of confounders in epigenetic analysis it is necessary (1) to use a battery with the existing co-normative data in the target population, which allows to evaluate representativeness of control and patients included in the study sample, (2) to verify the theoretically driven battery structure using normative population and a cohort of patients, (3) to balance groups of cases and controls on the number, age and sex, for which an individual matching of cases and controls is best suited, (4) to conduct an additional statistical analysis controlling for education and smoking.

AB - BACKGROUND: Mutations in the glucocerebrosidase gene (GBA) increase the risk of Parkinson's disease (PD) by 6-10 times in all populations and are associated with the early-onset of PD, development of cognitive impairment and presence of psychotic disorders. At the same time, polymorphic variants associated with the twofold increase in the risk of PD were also described in the GBA gene. AIM: To estimate the clinical features of PD in patients with mutations and polymorphic variants of the GBA gene. MATERIAL AND METHODS: Evaluation of motor, cognitive, emotional, psychotic and autonomic dysfunctions in patients with mutations (N370S, L444P) and polymorphic variants (E326K, T369M) in the GBA gene was performed using clinical scales. RESULTS: Patients with mutations (mGBA-PD), and with polymorphic variants (pGBA-PD) in the GBA gene were compared with the group of patients with sporadic PD (sPD). Compared to sPD, affective disorders (depression and anxiety) were more expressed in the mGBA-PD group (p=0.001) and the general GBA-PD group (p=0.001) assessed with Sheehan anxiety rating scale, in the pGBA-PD group (p=0.012) and the general GBA-PD group (p=0.05) assessed with the NPI, in the mGBA-PD (p=0.003), pGBA-PD (p=0.022), and general GBA-PD groups (p=0.001) assessed with the Hospital Anxiety and Depression scale (HADS 'A'), and in the pGBA-PD group (p=0.005) assessed with the HADS 'D'. Non-motor symptoms assessed with the PD-NMS were more expressed in the pGBA-PD patients (p=0.007) and in the total group with GBA-PD (p=0,014) compared to sPD. Cognitive impairment measured with MMSE was more marked in mGBA-PD patients (p=0.022). Differences in motor and non-motor clinical symptoms between pGBA-PD and mGBA-PD groups were not found. CONCLUSION: Thus, clinical features of non-motor symptoms were described both in carriers of GBA mutations and polymorphisms. Identification of the specific clinical phenotype of PD in carriers of GBA polymorphic variants is important due to their relatively high prevalence in PD patients.

AB - : The aim of the research - to study the Mexidol (ethylmethylhydroxypyridine succinate) effect on the factor induced by hypoxia (HIF-1alpha) expression in the frontal cortex of the brain in its ischemia. MATERIAL AND METHODS: The work was performed on the 64 male Wistar rats. The expression of HIF-1alpha was determined immunohistochemically. RESULTS AND DISCUSSION: It is determined that single intraperitoneal administration of Mexidol at a dose 120 mg/kg and oral administration at a dose 100 mg/kg three times a day for 14 days is not affected the expression of HIF-1alpha. Unilateral occlusion of the common carotid artery increases the expression of HIF-1alpha at 4 hours after the occlusion. Oral administration of Mexidol at a dose 100 mg/kg three times a day for 14 days before and after ischemia increases the expression of HIF-1alpha after 4 and 12 hours in comparison with the norm, on the 5th day in comparison with occlusion control. Thus, it has been established that Mexidol increases the expression of HIF-1alpha in the frontal cortex of rat brain not under normal conditions, but in unilateral occlusion of the common carotid artery.

AB - AIM: To reason the choice of methods of restoration of advanced hand activity depending on severity of motor disturbance in the top extremity. MATERIAL AND METHODS: Eighty-eight patients were randomized into 3 groups: 1) the mCIMT group, 2) the 'touch glove' group, 3) the control group. For assessment of physical activity of the top extremity Fugl-Meyer Assessment Upper Extremity, Nine-Hole Peg Test, Motor Assessment Scale were used. Assessment of non-use phenomenon was carried out with the Motor Activity Log scale. RESULTS AND CONCLUSION: At a stage of severe motor dysfunction, there was a restoration of proximal departments of a hand in all groups, neither method was superior to the other. In case of moderate severity of motor deficiency of the upper extremity the most effective was the method based on the principle of biological feedback - 'a touch glove'. In the group with mild severity of motor dysfunction, the best recovery was achieved in the mCIMT group.

AB - Traumatic brain injury (TBI) is one of the main reasons of death and disability in children and adolescents in Russia and abroad. Spasticity is a frequent outcome of the TBI that influences on the rehabilitation prognosis, degree of movement disorders and quality of life after trauma. Early spasticity correction and complex rehabilitation lead to the optimal recovery and prevent secondary complications. This review presents the current data about the prognostic role of the spasticity in children after TBI, methods of its correction and their scientific evidence. Limitations and challenges of per-oral antispastic agents are described especially for the patients with local spasticity. Attention is focused on the methods of treatment of local hypertonus, in particular botulinum toxin A (BTA) injections proved to be effective in adults with acquired brain injury. The article summarizes the results of international investigations, systematic reviews and consensus statements about the efficacy and safety of botulinum toxin treatment in children after the TBI. The authors describe an algorithm of the optimal patient selection and goal setting for BTA injections in children with acquired brain injury.

AB - Memantine is the first clinically available glutamate antagonist, with an antagonist action at the N-methyl-D-aspartate receptors in the brain, for correction of cognitive and behavioral functions in neurodegenerative disorders. Glutamate mediated excitotoxic neuronal damage has been implicated in Alzheimer's disease (AD) and other parkinsonism-related dementias and, therefore, memantine represents a novel mode of action to counteract the glutamate-mediated excitotoxicity. In moderate to severe AD, 20 mg of memantine shows a positive effect on cognition, mood, behavior and the ability to perform activities of daily living. Long-term studies show good tolerability of memantine with an acceptable side-effect profile. In recent years, there have been a proliferation of a number of companies producing generic memantine with different trade names. In Russia, the first memantine generic drug noojerone was approved in 2010 and its use has since been supported by a growing evidence base of efficacy in real life clinical practice. Postmarketing studies show that noojerone provides long term and effective therapy in patients with moderate and severe Alzheimer's dementia. This observation is supported by the clinically significant therapeutic effect of noojerone on cognitive and daily functioning, behavioral and psychotic symptoms of dementia and a reduction of the burden on caregivers. This generic version of memantine is affordable and, therefore, reduces financial burden on patients and improves compliance with treatment. PMID- 29171503 TI - [Prevention and treatment of hepatic encephalopathy]. AB - Hepatic encephalopathy is a common neuropsychiatric complication of serious liver diseases and serves as a marker for worsening of their course and increasing the risk of death. The principal pathogenesis factors of hepatic encephalopathy is the excessive formation of ammonia and its accumulation by astrocytes. A key role in the prevention and treatment of hepatic encephalopathy is played by drugs that prevent hyperammonemia and promote the removal of ammonia from the body, namely lactulose, rifaximin and L-ornithine-L-aspartate. L-ornithine-L-aspartate has proven clinical effectiveness in the treatment of hepatic encephalopathy, prevents the transformation of minimal hepatic encephalopathy into overt forms, increases the tolerability of psychotropic drugs used in the treatment of alcohol dependence, and improves cognitive functions. PMID- 29171504 TI - Intraoperative optical coherence tomography to evaluate the effect of the eyelid speculum on corneal pachymetry during accelerated corneal cross-linking (9 mW/cm2). AB - PurposeTo investigate intraoperative anterior segment optical coherence tomography (AS-OCT) to compare pachymetry changes between two methods (group 1: speculum-on, group 2: speculum-off during riboflavin instillation stage) during corneal cross-linking /CXL) (9 mW/cm2 for 10 min) in keratoconic patients.MethodsIn this interventional case series, 11 eyes (11 patients) in group 1 and 14 eyes (14 patients) in group 2 were enrolled. Pachymetry measurements by spectral domain OCT was performed at baseline, after epithelial removal, after 30 min of imbibition with riboflavin, and after UV irradiation. Repeated measures analysis of variance was used to compare the trend of changes in different stages of the procedure within and between two groups.ResultsThe corneal thinnest pachymerty (CTP) at baseline, after epithelial removal, 30 min of riboflavin instillation, and irradiation was 469.8+/-26.5, 438.0+/-27.1, 354.3+/-28.4, 367.1+/-31.8 microns in group 1 and 463.2+/-25.1, 438.0+/-27.1, 421.6+/-54.0, 386.9+/-34.0 microns in group 2, respectively. Group 1 showed a significantly greater decrease in the corneal pachymetry (P<0.001) during riboflavin instillation, while in group 2 a greater decrease in CTP was observed during the UV irradiation phase (P=0.002).ConclusionsUsing the intraoperative OCT, the speculum-off group had a more stable corneal pachymetry during riboflavin instillation time. Despite this, the effect was not lasting throughout the procedure; significant changes were noted in the corneal pachymetry at the end of operation in both groups; further highlighting the limitations imposed by corneal stromal shrinkage using isotonic dextran containing riboflavin solution for CXL.

AB - Inflammasomes, key molecular regulators that play an important role in inflammation, consist of a central protein, an adaptor protein ASC (apoptosis speck-like protein) and a caspase-1 protein. Upon activation, caspase-1 induces maturation of cytokines such as interleukin-1beta (IL-1beta) and interleukin-18 (IL-18). The release of these cytokines can result in inflammation. Inflammasomes are activated by a variety of factors and their activation involves complex signalling leading to resolution of infection, but can also contribute to the pathology of inflammatory, autoimmune, and infectious diseases. The role of NLRP1, NLRP3, NLRC4 and AIM2 inflammasomes in the pathogenesis of ocular diseases such as glaucoma, age related macular degeneration (AMD), diabetic retinopathy, dry eye and infections of the eye has been established over the past decade. In experimental studies and models, inhibition of inflammasomes generally helps to reduce the inflammation associated with these eye diseases, but as yet the role of these inflammasomes in many human eye diseases is unknown. Therefore, a need exists to study and understand various aspects of inflammasomes and their contribution to the pathology of human eye diseases. The goal of this review is to discuss the role of inflammasomes in the pathology of eye diseases, scope for anti-inflammasome therapy, and current research gaps in inflammasome-related eye disease.

The series is taken from the Faculty of General Dental Practice UK (FGDP[UK]) 2016 Good Practice Guidelines book on this topic, edited by A. M. Hadden. This particular article, the first in the series, describes what constitutes dental records. The principles are applicable to electronic and handwritten records.

PMID- 29171511 TI - Defensive dentistry and the young dentist - this isn't what we signed up for. AB - Why did I want to become a dentist? I wanted a job where I would be respected as a professional and could change the lives of others, using my hands. This, I thought, would be my ideal profession; one where I could walk into work with a smile on my face every day. Cue dental school a place where one is trained to become competent in all areas of general dentistry. As readers will appreciate, dentistry is a vast field and the question that comes to mind is how so many diverse and varied topics can be jam packed into a five-year course. There has always been a debate about what to put in, and therefore leave out. At my particular dental school, the first two years covered basic scientific theory, leaving three years to get into clinical dentistry with some 'other' aspects sprinkled in. Some of these aspects included general communication skills, record keeping and one or two practice visits at fancy dental practices to see how good life was as a general dental practitioner. In light of the profession's current climate and the rise of defensive dentistry, I aim to reflect on why many young graduates from all over the country feel out of touch with the profession so early on in their careers, and why some of these 'other' aspects of dentistry should have been covered much more comprehensively to prepare us for the big wide world.

AB - Lesions of the mouth are surprisingly common and vary from the totally innocuous to highly malignant neoplasms. As required for the management of all patients, a clear and concise history and a thorough clinical examination are essential. In addition, radiographs and other laboratory investigations may be required to formulate a differential diagnosis. A definitive diagnosis, on which treatment planning should always be based, can usually only be confirmed following a histological examination. This may be obtained through a biopsy or following total excision of a lesion. PMID- 29171518 TI - Help ease festive hardship among dentists and their families.

AB - Introduction Knowledge of tooth dimensions and relationships and ethnic variations in these parameters are important in the planning and provision of aesthetic dentistry.Aim The aim of the present study was to investigate the dimensions and relationships of the upper anterior teeth in young adults of Indian origin, living in an urban location in the UK, and to compare the data obtained with data pertaining to other ethnic groups.Materials and methods This was a qualitative, non-experimental, cross sectional descriptive study with ethical approval. The dependent variables were tooth dimensions and relationships. The independent variable was gender. Fifty male and 50 female young adult Indians were recruited to the study, according to predetermined criteria. Upper and lower, full arch impressions were obtained for each of the 100 participants. Stone cast were obtained from these impressions. The width and length of each upper anterior tooth included in the casts were measured using precision callipers. Anterior arch length was determined using a flexible measuring tape. All measurements were repeated at least three times to obtain consistent values. The error of the method was investigated by means of repeat measurements. The data obtained was analysed, and compared with existing data on tooth dimensions and used to investigate the presence of Golden Proportion relationships.Results The measurements obtained had a normal distribution. Statistical analysis revealed significant differences in the overall data for left and right canine width and length (P <0.05). No such differences were noted in respect of the upper central and lateral incisors. Also, significant differences (P <0.05) were found to exist between male and female subjects in respect of the width of all anterior tooth types, except for the upper right lateral incisor. There were significant differences in the length of the upper left central incisor and upper right and left canines between male and female subjects (P <0.05). Significant differences (<0.05) were found in the width to length ratios between right and left canines. No such differences were observed for incisors. There was an absence of Golden Proportion relationships.Conclusion Within the limitations of the present study, it is concluded that it is inappropriate to adopt a formulaic, left/right symmetrical approach to smile design in the provision of aesthetic dentistry for young adults of Indian origin.

AB - Has the state's manipulation of the NHS dental contract systems deliberately, or accidentally, had corrupting effects on the behaviours of some members of the dental profession? If the answer is 'possibly' or 'probably', then obvious questions that follow include, 'was this done deliberately' and if so, 'why'? Could this have been done for largely altruistic reasons, or was it done to achieve government control for minimum cost? Might this have been undertaken for political, financial or ideological reasons - regardless of any adverse longer term consequences for some patients or for some dental professionals? Might it have been done to take greater control of the dental profession on the grounds that all professions are a conspiracy against the laity, as the mildly paranoid George Bernard Shaw once alleged? Is it possible that some of this manipulation might have been done to help to disempower yet another profession, allegedly to 'modernise it', but perhaps to enslave it for its own reasons? Was this just another example of some statist politicians wanting to interfere in all aspects of UK society, regardless of their lack of specific understanding, or any proven expertise, in many areas? Could the state's manipulation of contracts and processes be regarded as an abuse of power by a virtual monopoly, which has been used to control a largely altruistic profession by imposing corrupting NHS dental contract systems with the most recent one involving 'units of dental activity' (UDAs)? Perhaps it was really about some politicians wanting ever more power, control or money - their usual drivers - with the dental and medical professions accidentally becoming casualties?

AB - Many women are exposed to carbon disulfide (C2) hazards at work every day. Working with C2 may cause some women to experience abnormalities in their reproductive health. Until now obtained data is generally concentrated on the health effects of C2 observed in the viscose industry. To date, C2 has not been studied precisely for its potential to have damaging effects on female reproductive system, especially the frequency of menstrual disturbances and the course of menopause. The aim of the study was to sum up female reproductive health hazards amongst women chronically exposed to C2 in their workplace in the viscose industry. In order to study the effect of C2 in the contemporary viscose industry, exposure measurements should be collected in prospective or cross sectional studies. In conclusion, reproductive health hazards for women chronically exposed to C2 in the workplace in the viscose industry are the following: 1) menstrual disorders essentially are more frequent than in the case of the healthy women, 2) for women chronically exposed to C2 the average menopausal age is statistically earlier, as compared to healthy women, 3) complex disturbances in neurohormonal system for women exposed to C2, resulting from toxic influences of C2, which cause the secretion of estrogens and progesterone in ovaries and dehydroepiandrosterone sulfate in the adrenal gland to diminish.

AB - OBJECTIVE: To determine the relationship among vitamin B12 status, obesity severity, and metabolic syndrome and its components in obese children.. METHODS: This case-control study was conducted at the School of Medicine, Gaziosmanpasa University, Tokat, Turkey, from January 2012 and October 2014, and comprised cases of obese and healthy children. The obese children were divided into three groups according to body mass index-standard deviation score quartiles. Group 1 included the first quartile, group 2 included the second and third quartiles, and group 3 included the fourth quartile. Patients with a body mass index of >95th percentile, according to reference curves for Turkish children and adolescents, were considered obese.Patients with a body mass index between15th and 85th percentile were considered to have normal weight. The World Health Organisation's modified metabolic syndrome criteria for children were used to diagnose metabolic syndrome.SPSS 19 was used for data analysis. RESULTS: Of the 256 participants, 153(59.8%) were obese and 103(40.2%) were healthy controls. The mean age of the obese children was 12.69+/-2.29 years and that of healthy controls was 13.05+/ 2.48 years. Mean vitamin B12 levels were significantly lower among obese children than healthy volunteers (p<0.001). Age and body mass index-standard deviation score were significantly associated with vitamin B12 status (r= -0.175, p=0.030; r= -0.210, p=0.09, respectively). CONCLUSIONS: Increase in body mass index standard deviation score was associated with a decrease in vitamin B12 levels. PMID- 29171554 TI - Evaluation of several classification methods in carpal tunnel syndrome. AB - OBJECTIVE: To investigate the performance and effectiveness of 4 classification methods including support vector machine, naive Bayes, classification tree, and artificial neural network in the detection of carpal tunnel syndrome. METHODS: This retrospective study was conducted at Yuzuncu Yil University, Van, Turkey, and comprised record of patients suspected of having carpal tunnel syndrome between January and December 2013. The evaluations included age, gender, and 6 electromyography variables, including right/left median nerve sensory velocity, right/left fourth finger peak latency difference, and right/left median nerve motor distal latency. We investigated the performance of classification methods such as support vector machine, naive Bayes, classification tree and artificial neural network in the patients using data obtained from electromyography scan. A total of 6 criteria were used for the assessment of performance, including: true positive rate, false positive rate, true negative rate, false negative rate, accuracy, and preciseness. RESULTS: Of the 109 patients, 88(80.7%) were women and 21(19.3%) men. Besides, 67(61.5%) participants had carpal tunnel syndrome and 42(38.5%) did not have it. On classification tree, only 2 variables, i.e. left fourth finger peak latency difference and right/left median nerve sensory velocity, were found to be statistically significant (p<0.001). Naive Bayes had the highest detection score (91.04%), followed by support vector machine (89.55%). CONCLUSIONS: Naive Bayes yielded better performance than all the other methods in the diagnosis of carpal tunnel syndrome, followed by support vector machine.

AB - OBJECTIVE: To assess if genotypes/diplotypes of vitamin D binding protein have any association with type 2 diabetes mellitus. METHODS: This case-control study was conducted from January 2013 to July 2015 at the endocrinology clinics of the Aga Khan University Hospital, Karachi, and comprised adult patients with type 2 diabetes and their age- and gender-matched healthy controls. Venous blood was obtained and assessed for serum/plasma 25 hydroxyvitamin D, parathyroid hormone, calcium, alkaline phosphatase and creatinine. Deoxyribonucleic acid was isolated and genotyping was done by polymerase chain reaction-restriction fragment length polymorphism procedures. RESULTS: Of the 330 participants, there were 165(50%) cases and as many controls. There were 116(70.3%) males and 49(29.7%) females in each group. The mean age of the patients was 48.82+/-9.23 years and that of the controls was 46.27+/-8.77 years (range: 22-70 years) (p=0.010) Mean serum concentration of 25 hydroxy vitamin D was significantly higher among the patients compared to the controls (p<0.001), but not significantly different by genotypes or diplotypes (p>0.05). Multiple conditional logistic regression revealed an association of group-specific 1-2 genotype with patients when adjusted for age, body mass index, and serum levels of 25 hydroxy vitamin D with matched adjusted odds ratio (95% confidence interval) being 3.1(1.22-7.88). CONCLUSIONS: Group specific 1-2 genotype of vitamin D binding protein gene was associated with the risk of type 2 diabetes. PMID- 29171556 TI - Assessment of the risk factors of hypertension among adult & elderly group in twin cities of Pakistan. AB - OBJECTIVE: To estimate the prevalence of hypertension and to explore the risk factors associated with it. METHODS: In a cross-sectional study, a population based survey was conducted on inhabitants of Rawalpindi-Islamabad region, 219 individuals; aged 18 years or above were included in the study. Blood pressure was measured along with information about individual's demographic and socio economic characteristics were obtained using a standard questionnaire.. RESULTS: Overall prevalence of hypertension was 29.22% (males: 21.9% and females: 78.1%) in individuals residing in Rawalpindi-Islamabad. High blood pressure is more associated with obesity (59.4%) and a progressive increase in hypertension was observed with increasing age. Bivariate analysis revealed that hypertension has a significant correlation (p-value<0.05) with age, gender, family status, weight and physical health. CONCLUSIONS: The study concludes that our generation is well aware about the risks and consequences of hypertension, but they still continue to make no or little effort in managing or preventing it. The factors contributing to hypertension are low physical activity, diet and lack of interest to maintain their health. PMID- 29171557 TI - Effects of supervised structured aerobic exercise training programme on level of Exertion, dyspnoea, VO2 max and Body Mass Index in patients with type 2 diabetes mellitus. AB - OBJECTIVE: To determine the effects of supervised structured aerobic exercise training programme on level of exertion, dyspnoea, maximum oxygen consumption, and body mass index in type 2 diabetics. METHODS: The randomised, controlled trial was carried out at Riphah Rehabilitation and Research Centre, Islamic International medical College Trust, Pakistan Railways General Hospital, Rawalpindi, Pakistan, from January 2015 to June 2016, and comprised type 2 diabetics. Sedentary individuals of both genders, aged40-70 years, diagnosed on World Health Organisation's criteria were included. Participants were randomly divided into two groups, i.e. A (experimental) and B (control), by toss and trial method. Intervention in the experimental group were supervised structured aerobic exercise training programme, routine medication and dietary, while the control group was treated by routine medication and dietary plan for 25 weeks at 3 days per week for both groups. Level of exertion, dyspnoea, maximum oxygen consumption and body mass index were assessed and documented at baseline (0 week) and at the completion of intervention (after 25 weeks). SPSS20 was used for data analysis. RESULTS: Of the 102 participants, there were 51(50%) in each group. Pre- and post intervention analysis showed that a 25-week training programme, routine medication, and dietary plan significantly improved level of exertion, dyspnoea, maximum oxygen consumption and body mass index (p<0.05)) in the experimental group compared to the control group treated with routine medication, and dietary plan. CONCLUSIONS: The supervised structured aerobic exercise training programme along with routine medication and dietary plan positively influenced level of exertion, dyspnoea, maximum oxygen consumption and body mass index than routine medication and dietary plan in patients with type 2 diabetes. PMID- 29171558 TI - Enhanced recovery after surgery (ERAS) protocol in stoma reversals. AB - OBJECTIVE: To compare the length of hospital stay and return of bowel movement using the conventional management versus 'enhanced recovery after surgery' protocol. METHODS: This study was conducted at the Civil Hospital, Karachi, from June 2014 to May 2015, and comprised patients undergoing stoma reversal. Patients were randomly allocated in two equal groups, i.e. A (treated with conventional peri-operative management) and B (with 'enhanced recovery after surgery' protocol). Prolonged ileus, wound infection and length of hospital stay between the two groups were compared. SPSS 20 was used for statistical analysis. RESULTS: There were 60 participants who were divided into two groups of 30(50%) each. Overall, 39(65%) patients were males and 21(35%) were females. The mean age was 27.80+/-9.99 years in group A and 23.87+/-4.56 years in group B. Besides, 25(83%) patients in group A had prolonged ileus compared to 3(10.7%) in group B (p=0.00). Moreover, 14(46.7%) patients in group A and 8(26.7%) patients in group B had wound infection (p=0.10). The mean duration of hospital stay was also less in group B compared to group A (p<0.05). CONCLUSIONS: The application of 'enhanced recovery after surgery' protocol was found to be safe. PMID- 29171559 TI - Prognostic importance of paraoxonase, arylesterase and mean platelet volume efficiency in acute ischaemic stroke. AB - OBJECTIVE: To study the prognostic importance activity of paraoxonase and arylesterase, and the value of mean platelet volume in patients with acute ischaemic stroke. METHODS: This case-control study was conducted at Harran University Hospital, Sanliurfa, Turkey, from January to June 2014, and comprised patients with symptoms of acute ischaemic stroke who presented to the emergency department. Paraoxonase activity, expressed in units per litre, or U/L, of serum, was evaluated in the absence of basal activity, and arylesterase activity was defined as micromoles, of phenol generated/min, and was expressed as U/L of serum. Mean platelet volume was measured as a routine parameter. SPSS 20 was used for data analysis. RESULTS: Of the 94 participants, 48(51%) were patients with acute ischaemic stroke and 46(49%) were control subjects. Moreover, 27(56.3%) patients were females and 21(43.7%) were males. In the control group, 26(56.5%) were females and 20(43.5%) were males. The mean age of patients was 68.39+/-11.83 years compared to controls' 65+/-9.95 years. Decreased activity of prognostic importance and arylesterase were significant in patients than in the controls (p= 0.016 and p= 0.001, respectively). The median platelets of patients was significantly lower than that of the controls (p=0.004). However, the median mean platelet volume values were similar in the both groups (p=0.568). Binary logistic regression analyses showed that the paraoxonase and arylesterase were risk markers for the patients. CONCLUSIONS: Decreased paraoxonase and arylesterase activity and decreased platelet counts were observed probably due to increased oxidative stress in acute ischaemic stroke patients.

PMID- 29171567 TI - An effective and doable interventional strategy to enhance vaccination coverage - are we ready to change? AB - OBJECTIVE: To evaluate the effect of patient reminder calls on improvement of routine vaccination coverage. METHODS: This prospective, interventional study was conducted at Rawal Institute of Health Sciences, Islamabad, Pakistan, from December 2014 to August 2016, and comprised babies enrolled at the time of 1st vaccination. Babies who were given bacillus Calmette-Guerin, oral polio vaccine were included. Mobile phone numbers of parents were noted. The 1st reminder call was given after 7 days if a baby did not report on the scheduled date. Similarly, 2nd and 3rd reminder calls were made after waiting for 7 days each time in case of non-reporting. Record of reporting and reminder calls was reviewed daily till all the enrolled babies crossed 15 months of age (scheduled time for 2nd dose of measles) plus 4 weeks. RESULTS: A total of 150 babies were enrolled at the time of 1st vaccination. Reporting without call within 01 week of scheduled date ranged from 52(34.66%) to 99(66%) for different vaccines. The 1st reminder call showed maximum improvement in reporting rate. The range of vaccination rate reached from 91(60.66%) to 132(88%). The 2nd call improved coverage rate range from 108(71.99%) to 140(93.33%). The 3rd call improved coverage rate from 113(75.32%) to 144(96%). Overall coverage rate achieved ranged from 112.5(75%) to 144(96%). CONCLUSIONS: Patient reminder calls showed significant effect in improvement of vaccination coverage rate of all antigens. PMID- 29171568 TI - Risk factors of cardiovascular disease and its recommendations in Pakistani context. AB - Cardiovascular diseases possess a major cause for fatality and disability the world over. Since last several decades, the rates of cardiovascular diseases related deaths have decreased in a number of high-income countries but increased in low- and middle-income countries with around 80% of the burden. Despite the seriousness of cardiovascular diseases in low- and middle-income countries, minimal attention is given to the prevention of cardiovascular diseases risk factors in South Asia, particularly in Pakistan. In addition, economic and political instability is accelerating the rates of cardiovascular diseases in the country. Practical efforts are required to enhance the understanding of cardiovascular diseases risk factors such as diet, physical activity, and tobacco control policies to support prevention and control at the population level. This paper reviews the major modifiable risk factors in Pakistan, highlights available preventive services, and presents the most likely ways to promote risk-factor reduction. PMID- 29171569 TI - HIV-1 in Pakistan: Where we stand? Where we will go? AB - Adherence to Islamic beliefs and being home to more than 190 million Muslims made many to believe that Pakistan was protected from human immunodeficiency virus or acquired immunodeficiency syndrome (HIV/AIDS). More than 30 years of HIV-1 epidemic, the reality is totally different now. HIV/AIDS is not only becoming a major health concern of Pakistan, but also in several other Muslim-majority countries like Malaysia, Iran and Indonesia having prevalence rates of 0.4%, 0.2% and 0.3%, respectively. While in most parts of the world, HIV-1 infections have decreased or stabilised. However, the countries where HIV-1 prevalence is increased by 25-35% has Muslim majority. The high-risk populations in these countries are drug users and immoral sexual behaviours that include practices forbidden in Islam. PMID- 29171570 TI - Retinitis pigmentosa genes implicated in South Asian populations: a systematic review. AB - Retinitis pigmentosais one of the most prevalent causes of inherited retinal dystrophies worldwide. The widespread custom of consanguineous marriages in South Asian countries puts the population at risk for autosomal recessive disorders including retinitis pigmentosa. This systematic review was done between May and December 2015.A comprehensive literature search was carried out using MEDLINE and CINAHL databases and all relevant articles on causative mutations for non syndromic Retinitis pigmentosa from 1999 till 2015 were included. Overall, 41 articles were identified involving 66 families; 28(68%)from Pakistan, 12(29%) from India and 1(2.4%) from Bangladesh. No data was available from the rest of countries in the region. Autosomal recessive was the most common pattern of inheritance and out of the known 60 genes thought to be involved in the pathogenesis of non-syndromic Retinitis pigmentosa, 32(53%) were identified in South Asia. Although significant progress has been made in this regard, there are many more loci that are yet to be identified. Our study found that significant gaps in knowledge exist due to lack of reported literature from countries other than Pakistan and India and the absence of cost-effective screening programmes in place. PMID- 29171571 TI - Bacterial contamination of medical uniforms: a cross-sectional study from Suzhou city, China. AB - Few studies have been conducted which evaluate the prevalence of contamination of medical uniforms in China. The present study was designed to explore the characteristics of uniform contamination and associated factors. A total of 120 participants were enrolled in the study and 122 uniforms were sampled. Each uniform was sampled at three different sites to determine the colonisation of microorganisms. A total of 366 swab samples were cultured; 294 (80.3%) samples yielded various microorganisms and 75(61.5%) uniforms were contaminated with bacteria. The uniforms of medical students had the highest prevalence of contamination. The cuffs of uniforms were the most easily infected with bacteria. Participants who wiped their hands at the back of uniforms had higher contamination rate in the hanging part of uniforms. Our study demonstrated that medical uniforms can harbour microorganisms. Proper handling of medical uniforms and adequate education to medical staffs are required to decrease healthcare associated infections. PMID- 29171572 TI - Susceptibility pattern of methicillin resistant Staphylococcus aureus to vancomycin and other alternate agents: report from a private sector hospital laboratory. AB - With increasing prevalence of methicillin resistant Staphylococcus aureus in clinical settings and injudicious use of antibiotics, resistance among MRSA against commonly used antibiotics is increasing. To assess the susceptibility pattern of MRSA against vancomycin, linezolid, tigecycline, rifampicin, fosfomycin fusidic acid, clindamycin, trimethoprim-sulfamethoxazole and teicoplanin, minimum inhibitory concentrations (MICs) for given antimicrobials were performed on 234 MRSA clinical isolates using automated VITEK 2 system. Vancomycin, linezolid, rifampicin, clindamycin, co-trimoxazole and teicoplanin susceptibilities were interpreted according to CLSI breakpoints, while tigecycline, fosfomycin and fusidic acid were interpreted according to BSAC breakpoints. All isolates were found susceptible to vancomycin, tigecycline, teicoplanin and linezolid. Non-susceptibility of the isolates for rifampicin, fusidic acid and fosfomycin was noted for 58(25%). Co-trimoxazole and clindamycin were found less susceptible showing high resistance rates of 61.5% and 42.3%, respectively. Vancomycin resistance was not found, however an increased MIC of 1 mg/ml was observed in about 25% of clinical strains. Increase in vancomycin MICs in MRSA is of concern and alternative antimicrobial options must be evaluated and considered for treatment of MRSA infections. Continuous antimicrobial surveillance is needed to monitor resistance patterns and detect possible emergence of vancomycin non-susceptible isolates.

Mean arterial pH was 6.8+/-0.5 on arrival. Ethanol was given to 30(88%) patients and 12(32%) patients received bicarbonate for immediate treatment. A total of 15 (42.8%) patients underwent dialysis, out of which only 5 (33.3%) patients survived. Overall, 19 (54.3%) patients expired secondary to methanol ingestion. PMID- 29171575 TI - A case of hypotriploid chromosome in a patient with acute lymphoblastic leukaemia. AB - TA 58-61, XXXX, hypotriploid chromosome was detected in the cytogenetics report of a 28 years old female patient, known case of B-cell Acute Lymphoblastic Leukaemia. On admission, the patient had normal physical examination findings and mental status, except history of fever spikes and generalized bone pains. The patient was admitted for induction of chemotherapy. Bone Marrow/Trephine biopsy report showed diffuse infiltration with blast cells with overall cellularity around 80-85% and suppressed normal haematopoiesis. Hypotriploid chromosome number in patients with B-cell Acute Lymphoblastic Leukaemia is a unique finding which, according to WHO classification of ALL, is an important prognostic factor itself and these cases have a favourable prognosis. There are only a few medical reports published about cases with similar presentations in Pakistan. Therefore, this case is very unique and further work should be done for better understanding of similar presentations and to find out more about its epidemiology. PMID- 29171576 TI - An elusive case of dermatomyositis. AB - Dermatomyositis is an inflammatory myopathy of unknown aetiology. Muscle involvement may eventuate later in the disease course in some patients, who may present with typical skin disease without clinical signs of myopathy and are referred to as dermatomyositis sine myositis. A 48 year old female presented with intermittent urticaria like rashes, diffuse asymmetrical swelling of proximal limbs, pain in small joints of hands and fatiguability. Initial laboratory work up for immune markers was negative. Three years later, she developed heliotrope rash and periorbital oedema with no evidence of muscle weakness and was labeled as amyopathic dermatomyositis. After an interval of one year, she developed profound weakness and significantly raised CPK. Patient responded well to steroids and Azathioprine and improved both clinically and biochemically. PMID- 29171577 TI - A case of Vogt Koyanagi Harada disease in a 16 year old girl. AB - Vogt Koyanagi Harada (VKH) is an autoimmune disease with widespread systemic manifestations. It typically presents with bilateral sudden painless loss of vision. It is mainly characterized by serous retinal detachment, iridocyclitis and choroidal swelling. The disease is more common in females and maximus incidence occurs in the age group of 30 to 40 years. We present a case of a 16 year-old girl who presented with sudden bilateral painless loss of vision. Fundus examination and OCT scanning confirmed bilateral serous retinal detachment. Patient was started on IV methylprednisolone and the patient showed excellent response with marked improvement in visual acuity. VKH is very uncommon in children and is usually missed. It is important for general practitioners and ophthalmologists to know about this rare cause of painless loss of vision so that it could be managed adequately. PMID- 29171578 TI - Neurobrucellosis: A report of two cases. AB - Neurobrucellosis is a rare complication of brucellosis, a common zoonosis with multisystem involvement. Its clinical presentation is quite heterogeneous and diagnosis requires a high index of suspicion in patients from endemic areas. We present two cases of neurobrucellosis with widely varying clinical involvement from a tertiary center in Pakistan. Our case report emphasizes that neurobrucellosis should be considered in evaluation of patients with unexplained neurological symptoms.. PMID- 29171579 TI - Common clinical features of pediatric multiple sclerosis in Pakistan - A report of 15 cases. AB - The aim of this note is to assess the common clinical features of paediatric multiple sclerosis (PMS) in Pakistan. For this purpose, 150 MS patients with the age range of (1-72) years and mean age (34.2+/-11.09) years were studied during the period 2010 to 2015 from MRI centers of Pakistan.

AB - The International Diabetes Federation (IDF), in collaboration with the Diabetes and Ramadan (DAR) International Alliance, has recently published practical guidelines on the management of diabetes and Ramadan .The risk stratification categorizes all persons wishing to fast into three groups, based upon potential risk. In spite of evidence to the contrary, all persons using premixed insulin are categorized as having high risk. In this article, we present data from randomized controlled trials, and discuss the placement of premixed insulin in the risk stratification framework. PMID- 29171582 TI - The sixth vital sign in diabetes. AB - The vital signs are an integral part of clinical methods. In diabetes, determination of plasma glucose can be taken as the fifth vital sign. The sixth vital sign is well being, which can easily be measured by two item questionnaires designed to assess distress, depression and coping skills. This sign is essential for the screening and follow up of persons living with diabetes, as it provides an idea of quality of care, helps plan therapeutic interventions, and serves as a surrogate for prognosis or outcome. Inclusion of the sixth vital sign reflects the relevance of the bio-psychosocial model of health to diabetes care.

AB - OBJECTIVE: To determine knowledge and misconceptions about asthma among the local population.. METHODS: This cross-sectional study was conducted at four tertiary care hospitals; Aga Khan University Hospital, Civil Hospital Karachi, Jinnah Postgraduate Medical Centre and Ojha Institute of Chest Diseases, Karachi, from October to November 2016, and comprised hospital attendants. The questionnaire used in the study comprised 26 questions answered with a true, false or not sure answer.SPSS 20 was used for data analysis. RESULTS: There were 400 participants. The overall mean age was 41.2+/-14.2 years, and 214(53.5%) of the participants were males. Moreover, 75(19%) participants thought that asthma was a psychological disorder while 181(45%) considered it an infectious disease. Nearly 174(43.5%) believed that inhaled medications had significant side effects. Besides, 264(66%) participants considered steam inhalation to be an effective treatment for asthma, 269(67%) thought that patients with asthma should avoid rice in their diet and 167(42%) considered milk as a common trigger. CONCLUSIONS: Participants' knowledge about asthma was poor and misconceptions were common about the condition.

AB - A cross-sectional study was carried out at Shifa International Hospital Islamabad over a period of 6 months, to determine the frequency and compare the different lifestyle modifications among patients with Gastroesophageal Reflux Disease (GERD) of different monthly income groups. Two hundred patients of GERD were enrolled in the study and divided into two groups based on monthly income less than and more than Rs. 30,000 respectively. Data was analyzed using SPSS 21. Descriptive statistics were calculated. Chi-square test was applied keeping p value <0.05. Mean age was 40+/-13 years, 82 (41%) males and 118 (59%) females. Walking was undertaken by 32% after meals and 87.5% consumed tea. Significant difference was seen between income groups and higher intake of fried and spicy foods respectively. Thus, effort needs to be made in creating awareness and counseling patients to practice lifestyle modifications to reduce GERD symptoms and stop sole reliance on medications.

AB - Fluorescence measurement is the main technology for post-amplification DNA detection in automated systems. Direct electrical reading of DNA concentration in solution could be an interesting alternative to go toward more miniaturized or less expensive devices, in particular in the pathogen detection field. Here we present the detection of short bacterial biomarkers with a direct impedancemetric measurement, within solutions of amplified and elongated DNA sequences in a microchannel. This technology relies on the electrohydrodynamic instability occurring in solutions of long charged macromolecules in a strong electric field. This instability specifically induces the aggregation of long DNAs and triggers conductivity variations that can be monitored by on-contact conductometry. An innovative isothermal amplification and elongation strategy was developed, combining SDA and HRCA reactions, in order to yield long DNAs suitable to be detected by the above principle, from a dilute initial DNA target. In contrast with previous label-free detection methods, this new strategy is very robust to matrix effects, thanks to the unique molecular weight dependence of the instability, coupled with this specific DNA amplification strategy. We demonstrate the detection of a 1 pM gene sequence specific to Staphylococcus aureus, in a portable system.

AB - A new water soluble and fluorogenic probe (L) that can demonstrate a specific ratiometric detection of a SO2 derivative (SO32-) in 100% aqueous medium and live cells has been designed and synthesized. The detection process can be visualized by the naked eye, as the orange-red fluorescence of L turns into a strong blue fluorescence upon interaction with SO32-. L displayed several beneficial attributes such as detection in complete aqueous medium, extremely fast response time along with high selectivity and sensitivity. The ratiometric sensing was attributed to the selective nucleophilic addition reaction of SO32- with L. The probe was further used to develop a low cost microfluidic sensor device (MUPAD). The probe was biocompatible and its potential to sense SO32- in mitochondria was captured in live HeLa cells.

PMID- 29171598 TI - Continuous wave random lasing in naturally occurring biocompatible pigments and reduction of lasing threshold using triangular silver nanostructures as scattering media. AB - Random lasers have enormous applications in several fields including speckle-free imaging and bio-imaging. Thus, recently, random laser (RL) generation (mostly under pulsed operation) has been demonstrated in several commercial organic dyes with high photoluminescence quantum yields (PLQY). Although some commercial organic dyes have high PLQYs, these have several limitations; particularly, these dyes are not bio-compatible and thus cannot be used in in vivo bio-imaging. In this study, rarely reported bio-inspired continuous-wave (CW) RL generation has been demonstrated at ca. 674 nm, pumped by a low power He-Ne laser, in naturally occurring pigments of Hibiscus rosa-sinensis leaves extract (HRLe). The lasing threshold was reduced by ~2.4 times from 40.7 W cm-2 (without scatterer) to 16.8 W cm-2 using anisotropic triangular nanostructures of silver (TNS) as a scatterer with a typical number density of 8 * 1015 nos. per ml. Unprecedentedly, further RL generation at ca. 691.7 nm with spectrally narrowed emission modes with a line width of ca. 1 nm along with a very low lasing threshold of 15 W cm-2 has been demonstrated in a thin film of polyvinyl alcohol doped with methylene blue dye and TNS. This study will initiate a new era of development of bio-inspired RL for bio-photonics applications.

AB - Ginger, which has been widely used for dietary condiment, has been reported to improve memory dysfunction in an animal model of Alzheimer's disease (AD). Recently, a few trials have been carried out to enhance the effects of ginger by improving the bioavailability of its relevant components via fermentation. Some reports have suggested that the fermented ginger has the ability to affect the AD in vitro systems; however, its anti-amnesic effects on an in vivo model still remain to be investigated. In the present study, we aimed to investigate the neuroprotective effects of ginger fermented with Schizosaccharomyces pombe (FG) in the in vivo models of AD. The neuroprotective effects were investigated by employing behavioral, western blotting, and immunohistochemical assays. The administration of FG improved recognition memory, impaired by scopolamine injection, than that of non-fermented ginger. In addition, FG ameliorated memory impairment in amyloid beta1-42 (Abeta1-42) plaque-injected mice via protecting neuronal cells in the CA3 area of the mouse hippocampus. Moreover, FG reinstated the pre- and postsynaptic protein levels decreased by Abeta1-42 plaque-toxicity. Overall, these data suggest that FG attenuates memory impairment in Abeta1-42 plaque-induced AD mice through inhibition of neuronal cell loss and synaptic disruption.

AB - Polymer solar cells are a promising technology for the commercialization of low cost, large scale organic solar cells. With the evolution of high efficiency (>13%) non-fullerene polymer solar cells, the stability of the cells has become a crucial parameter to be considered. Among the several degradation mechanisms of polymer solar cells, burn-in photo-degradation is relatively less studied. Herein, we present the first systematic study of photo-degradation of novel PBDB T:ITIC fullerene-free polymer solar cells. The thermally treated and as-prepared PBDB-T:ITIC solar cells were exposed to continuous 1 sun illumination for 5 hours. The aged devices exhibited rapid losses in the short-circuit current density and fill factor. The severe short-circuit current and fill factor burn in losses were attributed to trap mediated charge recombination, as evidenced by an increase in Urbach energy for aged devices. PMID- 29171601 TI - Debye ring diffraction elucidation of 2D photonic crystal self-assembly and ordering at the air-water interface. AB - We fabricate 2D photonic crystals (2DPC) by spreading a dispersion of charged colloidal particles (diameters = 409, 570, and 915 nm) onto the surface of electrolyte solutions using a needle tip flow method. When the interparticle electrostatic interaction potential is large, particles self-assemble into highly ordered hexagonal close packed (hcp) monolayers. Ordered 2DPC efficiently forward diffract monochromatic light to produce a Debye ring on a screen parallel to the 2DPC. The diameter of the Debye ring is inversely proportional to the 2DPC particle spacing, while the Debye ring brightness and thickness depends on the 2DPC ordering. The Debye ring thickness increases as the 2DPC order decreases. The Debye ring ordering measurements of 2DPC attached to glass slides track measurements of the 2D pair correlation function order parameter calculated from SEM micrographs. The Debye ring method was used to investigate the 2DPC particle spacing, and ordering at the air-solution interface of NaCl solutions, and for 2DPC arrays attached to glass slides. Surprisingly, the 2DPC ordering does not monotonically decrease as the salt concentration increases. This is because of chloride ion adsorption onto the anionic particle surfaces. This adsorption increases the particle surface charge and compensates for the decreased Debye length of the electric double layer when the NaCl concentration is below a critical value.

AB - A benchmark for structural interpretation of the 31P NMR shift and the 2JP,C NMR spin-spin coupling in the phosphate group was obtained by means of theoretical calculations and NMR measurements in diethylphosphate (DEP) and 5,5-dimethyl-2 hydroxy-1,3,2-dioxaphosphinane 2-oxide (cDEP). The NMR parameters were calculated employing the B3LYP, BP86, BPW91, M06-2X, PBE0, KT2, KT3, MP2, and HF methods, and the 6-31+G(d), Iglo-n (n = II, III), cc-pVnZ (n = D, T, Q, 5), aug-cc-pVnZ (n = D, T and Q), and pcS-n and pcJ-n (n = 1, 2, 3, 4) bases, including the solvent effects described with explicit water molecules and/or the implicit Polarizable Continuum Model (PCM). The effect of molecular dynamics (MD) on NMR parameters was MD-calculated using the GAFF force field inclusive of explicit hydration with TIP3P water molecules. Both the optimal geometries and the dynamic behaviors of the DEP and cDEP phosphates differed notably, which allowed a reliable theoretical benchmark of the 31P NMR parameters for highly flexible and structurally constrained phosphate in a one-to-one relationship with the corresponding experiment. The calculated 31P NMR shifts were referenced employing three different NMR reference schemes to highlight the effect of the 31P NMR reference on the accuracy of the calculated 31P NMR shift. The relative Deltadelta(31P) NMR shift calculated employing the MD/B3LYP/Iglo-III/PCM method differed from the experiment by 0.16 ppm while the NMR shifts referenced to H3PO4 and/or PH3 deviated from the experiment notably more, which illustrated the superior applicability of the relative NMR reference scheme. The 2JP,C coupling in DEP and cDEP calculated employing the MD/B3LYP/Iglo-III(DSO,PSO,SD)/cc PV5Z(FC)/PCM method inclusive of correction due to explicit hydration differed from the experiment by 0.32 Hz and 0.15 Hz, respectively. The NMR calculations demonstrated that reliable structural interpretation of the 31P NMR parameters in phosphate must involve both the structural and the dynamical components.

AB - Calix[4]arenes are versatile ligands, capable of supporting the formation of a wide variety of polymetallic clusters comprising 3d, 4f or 3d-4f metal ions. Calixarene-based metal ion fragments act as both bridging and structure capping moieties in these systems, and this behaviour is systematically extended upon moving to bis-calix[4]arene, a relatively new ligand in which two calix[4]arenes are tethered at the methylene bridge position. N,O-Ligands greatly influence cluster formation with bis-calix[4]arene, affording a remarkable mixed-valence [MnMnMn] cluster that displays coordination chemistry typical of each ligand type, but also new structure capping behaviour for the latter. PMID- 29171604 TI - Sensitivity-enhanced detection of non-labile proton and carbon NMR spectra on water resonances. AB - Chemical exchange saturation transfer (CEST) experiments enhance the NMR signals of labile protons by continuously transferring these protons' saturation to an abundant solvent pool like water. The present study expands these principles by fusing into these experiments homonuclear isotropic mixing sequences, enabling the water-enhanced detection of non-exchangeable species. Further opportunities are opened by the addition of coupling-mediated heteronuclear polarization transfers, which then impose on the water resonance a saturation stemming from non-labile heteronuclear species like 13C. To multiplex the ensuing experiments, these relayed approaches are combined with time-domain schemes involving multiple Ramsey-labeling experiments imparting the frequencies of the non-labile sites on the water resonance, via chemical exchange. 13C and 1H NMR spectra were detected in this fashion with about two-fold SNR amplification vis-a-vis conventionally detected spectroscopies. When combined with non-uniform sampling principles, this methodology thus becomes a sensitive alternative to detect non-exchangeable species in biomolecules. Still, multiple parameters including the scalar couplings and solvent exchange rates, will affect the efficiency and consequently the practicality of the overall experiment.

PMID- 29171606 TI - Dynamics of poly(vinyl butyral) studied using dielectric spectroscopy and 1H NMR relaxometry. AB - Dielectric Spectroscopy (DS) and 1H Fast Field-Cycling (FFC) NMR relaxometry were applied for understanding the dynamic behavior of the amorphous ter-polymer poly(vinyl butyral) (PVB) across the glass transition temperature (Tg = 70 degrees C by Differential Scanning Calorimetry). Above Tg, main chain segmental motions (alpha relaxation) were detected and characterized using both DS and FFC NMR relaxometry. The correlation times extracted by the analysis of DS and FFC NMR relaxometry data agreed within a factor of three and showed a Vogel-Fulcher Tammann temperature dependence, with an associated Tg of 69 degrees C and a fragility of 155 for PVB glass. Below Tg, a secondary process (beta relaxation) was revealed by DS, and was ascribed to reorientations of the vinyl alcohol dipoles due to local twisting motions with an associated activation barrier of 11 kcal mol-1. The beta process was also found to contribute to 1H NMR relaxation above Tg. PMID- 29171607 TI - Towards single egg toxicity screening using microcoil NMR. AB - Planar microcoils with diameter ranging from 20 to 1000 MUm I.D. (130-1130 MUm O.D.) are evaluated for their applications in NMR spectroscopy. The coils are first overfilled with a standard sucrose solution and compared against each other. Coils with smaller I.D. (<=100 MUm) perform extremely well. One hypothesis is that as the coils get smaller the volume occupied by the copper turns increases relative to the open I.D.; as such a large proportion of the sample is brought in close proximity to the coil turns and likely gives rise to strong sample-coil magnetic coupling, which increases the signal. The applications of the planar microcoils are demonstrated on Cypselurus poecilopterus (fish) and Daphnia magna (water flea) eggs. A single D. magna egg on a 50 MUm coil yielded at least 3000 times the mass sensitivity (~9,000,000 time saving) when compared to a 5 mm probe. This value could be at least 4 times higher if the B1 homogeneity of the coils could be improved. With the current design, 80% of the signal is lost in multiple pulse experiments that rely on phase inversion and signal cancellation between scans. The data were extrapolated to predict that biological samples as small as ~4 MUm may become accessible via planar microcoil designs. To fulfill their potential for in situ metabolic screening, specialized magnetic susceptibility matched sample holders that restrict the sample to the homogeneous B1 field region (i.e. within the 90% RF field) of the coil and advanced experiments that narrow spectral lines, suppress lipids and disperse signals into multiple dimensions will be required. PMID- 29171608 TI - Template-free synthesis and structural evolution of discrete hydroxycancrinite zeolite nanorods from high-concentration hydrogels. AB - We report the synthesis and characterization of hydroxycancrinite zeolite nanorods by a simple hydrothermal treatment of aluminosilicate hydrogels at high concentrations of precursors without the use of structure-directing agents. Transmission electron microscopy (TEM) analysis reveals that cancrinite nanorods, with lengths of 200-800 nm and diameters of 30-50 nm, exhibit a hexagonal morphology and are elongated along the crystallographic c direction. The powder X ray diffraction (PXRD), Fourier transform infrared (FT-IR) and TEM studies revealed sequential events of hydrogel formation, the formation of aggregated sodalite nuclei, the conversion of sodalite to cancrinite and finally the growth of cancrinite nanorods into discrete particles. The aqueous dispersion of the discrete nanorods displays a good stability between pH 6-12 with the zeta potential no greater than -30 mV. The synthesis is unique in that the initial aggregated nanocrystals do not grow into microsized particles (aggregative growth) but into discrete nanorods. Our findings demonstrate an unconventional possibility that discrete zeolite nanocrystals could be produced from a concentrated hydrogel.

PMID- 29171610 TI - Biological application of water-based electrochemically synthesized CuO leaf-like arrays: SERS response modulated by the positional isomerism and interface type. AB - Cupric oxide leaf-like nanostructures (CuONSs) (average dimensions: 80-180 nm in width and 400-750 nm in length) were synthesized via anodic electrochemical dissolution of copper in an ethanol solution containing LiCl electrolyte and water. Ultraviolet-visible (UV-Vis), Fourier-transform infrared (FT-IR), and Raman spectroscopies as well as scanning electron microscope (SEM), high resolution transmission electron microscopy with energy dispersive X-ray (HD-TEM EDS), X-ray photoelectron spectroscopy (XPS), and X-ray powder diffraction (XRD) were used to explore the metal surface plasmon, size, rheology, and structure of CuONSs. Then, pyridine alpha-aminophosphinic acid isomers (alpha-, beta-, and gamma-NHPy) were synthesized and assembled on the CuONS/air and CuONS/aqueous solution interfaces at the pH level of solution = 7. Differences in adsorption and thus in the spectral response resulting from positional isomerism were examined by surface-enhanced Raman scattering (SERS) with an excitation wavelength of 785 nm. The manner of interaction of the investigated isomers with CuONSs in an aqueous solution was discussed in detail and compared with that at the CuONS/air interface. For gamma-NHPy, at the CuONS/water interface, the time dependent changes in the spectral profile were observed and analyzed. For beta NHPy at the CuONS/air interface, tip-enhanced Raman scattering (TERS) measurements were performed. These measurements allowed observing single molecule behavior and avoiding interference from the molecule's surrounding environment.

AB - We report a complete suppression of the coffee-ring effect resulting in the formation of loosely packed two-dimensional particle monolayers by controlled evaporation of sessile drops containing soft microgel particles. These particulate deposits show gradual order-to-disorder transitions that are not abrupt like deposits of hard colloids. The areal coverage of the monolayer deposits can also be precisely controlled by tuning the particle concentration. The preferential adsorption of soft-microgel particles to the water-vapor interface, and their radial flow along the interface towards the drop edge facilitates the creation of the novel monolayer deposits. PMID- 29171612 TI - Design of superhalogens using a core-shell structure model. AB - Superhalogens, which have larger electron affinity than any halogen, play an important role in physical chemistry and materials design because of their applications in hydrogen storage and lithium-ion batteries. Inspired by the unique geometries and electronic properties of II-VI/III-V cage clusters, particularly the experimentally synthesized B12N12, we propose a core-shell structure model to design new superhalogens. The idea is assessed by conducting ab initio calculations on endohedral cage clusters X@B12N12 (X = F, Cl, Br) and other similar systems. With an exceptionally large electron affinity of 5.36 eV, the stable F@B12N12 cluster behaves as a novel superhalogen that can serve as a building block for Li salts and hyperhalogens. The findings highlight a new route for the discovery of superhalogens and provide useful building blocks for the bottom-up design of materials.

AB - We report on radical polarization and optically-driven liquid DNP using nitroxide radicals functionalized by photoexcitable fullerene derivatives. Pulse laser excitation of the fullerene moiety leads to transient nitroxide radical polarization that is one order of magnitude larger than that at the Boltzmann equilibrium. The life time of the radical polarization increases with the size of the fullerene derivative and is correlated with the electronic spin-lattice relaxation time T1e. Overhauser NMR signal enhancements of toluene solvent protons were observed under steady-state illumination, which replaced microwave irradiation.

Prospective evaluation of the Danish national Job & Body campaign. AB - Objectives This study evaluates the Danish national Job & Body campaign on beliefs about musculoskeletal pain and work. Methods Initiated in 2011, a national campaign in Denmark targeted public sector employees with a mixture of networking activities, workplace visits, and a mass media outreach with topics related to job and body (eg, musculoskeletal pain, movement and work) and creating balance between demands at work and physical capacity. At baseline (2011) and at four time points until the end of 2014, random cross-sectional samples of >=>=1000 representative public sector employees (total N=5012) replied to eight questions concerning beliefs about musculoskeletal pain and work. Changes over time were modelled using general linear models (averaged for all questions, 0-100 points, where 0 is completely negative and 100 completely positive) and logistic regression analyses (for the single questions) controlling for age, gender and a number of work-related factors. Results At the last follow up in 2014, 17.3% of public sector employees were familiar with the campaign. Beliefs about musculoskeletal pain and work were 3.4 points (95% CI 2.4-4.3) higher than at baseline. For the single questions, 4 out of 8 showed improved odds for more positive beliefs [odds ratios (OR) of 1.28-1.89]. Conclusion During follow-up of the national campaign, beliefs about musculoskeletal pain and work were more positive among public sector employees in Denmark. Due to the time-wise mixture of several campaign activities, the isolated effect of each component could not be disentangled. Whether changes in health occurred remain unknown. PMID- 29171639 TI - Nutritional supplements in depressive disorders. AB - There is increasing evidence about the role of nutrients in mental health. An adequate intake of nutrients contributes to better overall health and mental health in particular. Major depression is a severe mental illness with a high prevalence for which effective treatments exist but not in all cases the patient’s remission is achieved. Therefore, it is increasingly aimed at optimizing the supply of nutrients necessary for adequate brain functioning as adjunctive therapy to antidepressant treatment in depressive disorders. In this article we review those nutrients that have been related to depression: Omega-3 fatty acids, B vitamins, s-adenosylmethionine, tryptophan, magnesium, zinc and probiotics. PMID- 29171640 TI - Nutritional supplements in Anxiety Disorder. AB - In recent years, a direct relation between the occurrence of anxiety disorders, sleep disturbances, and mood disorders has been observed as a consequence of poor or inadequate diet. Eating habits in Western societies have greatly changed in recent decades, with an increase in the consumption of foods low in vitamin and mineral content, high in caloric value, and rapidly prepared and easily consumed. It may be that the new lifestyles that directly affect family organization and planning interfere with following a proper diet. However, with increasing frequency, especially among young adults, there is interest in healthy and balanced nutrition, as well as learning culinary techniques. We reviewed the literature for this study, and describe the concept of anxiety and its existence in relation to dietary disorders, as well as alternatives for the treatment of these symptoms. The characteristics of these disorders and their impact on patients are analyzed. The information used in this work was obtained mainly from PubMed, PsycARTICLES, PsycCRITIQUES, and PsycINFO. It was retrieved using the keywords “mental health”, “nutrition”, “diet”, “phytotherapy”, “natural alternatives”, “anxiety”, “mood”, and “sleep disturbance”. PMID- 29171641 TI - Dietary supplements in child and adolescent psychiatry. AB - Complementary and alternative treatments, including dietary supplements, are very popular and increasingly used in developed countries. Some features such as accessibility, ease of use, the possibility of self-administration and the belief they are safe without side effects, have led to an increase in their consumption. However, there is limited evidence of the effectiveness and safety of these treatments because of methodological issues. The level of scientific evidence is particularly low and weak in the field of child and adolescent Psychiatry. The purpose of this article is to give an updated overview of dietary treatments in this area. We make a brief introduction about general questions, including legal aspects, and propose general practical recommendations for a proper management by the families that choose these treatments. We focus on reviewing the current state of research into dietary treatments in some childhood and juvenile psychiatric disorders, highlighting current evidence of specific treatments. The final purpose of this article is to describe the level of current evidence on dietary treatments and to provide professionals involved in the care of children and adolescents with a useful tool to help, guide and educate families about their use in order to achieve the greatest benefit to patients. PMID- 29171642 TI - Dietary supplements for cognitive impairment. AB - Alzheimer disease and the other neurodegenerative dementias as yet have no curative treatment. For this reason, the prevention of these conditions and non pharmacological treatments are important fields of research at present. The Mediterranean diet (rich in fruits, vegetables, legumes, and olive oil, with regular fish consumption and low consumption of dairy products and meats) has been shown to reduce the incidence of mild cognitive impairment (MCI) and, probably, the conversion of MCI to dementia. Vitamins, especially vitamin E and the vitamins of the B group, have also been associated with the prevention of cognitive impairment due to their antioxidant effects. Ginkgo biloba is one of the most widely used supplements in the world for cognitive improvement because of its possible effects as a vasodilator and facilitator of cerebral vascularization. Green tea polyphenols have shown beneficial effects in different diseases, including cognitive impairment. Cerebral aging is associated with changes in the lipid composition of neuronal membranes, so it has been suggested that treatment with phospholipids like phosphatidylcholine and phosphatidylserine could favor cognitive improvement. Similarly, polyunsaturated and omega-3 fatty acids, and docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) supplements are associated with a beneficial effect on cognitive function due to the cumulative summation of factors that ultimately favor membrane permeability and neuronal functioning. PMID- 29171643 TI - Nutritional supplements in psychotic disorders. AB - There is growing interest about the potential of diet and nutrients to improve the mental health of the population and for the treatment of psychiatric disorders. In the case of schizophrenia, the limitations of antipsychotic drugs to achieve adequate rates of clinical remission and functional recovery have promoted the search for complementary approaches. This narrative review approaches the dietary patterns and interventions in schizophrenia, efficacy of specific nutrients and therapeutic modulation of the gut microflora by probiotics. As a whole, schizophrenia patients follow a low-quality diet and are exposed to deficiencies in various nutrients that are essential for brain functioning. Although clinical trials with nutritional supplements are still limited and have inconsistent results, specific nutrients, as Omega-3, vitamin D and Group B vitamins can be useful as complementary strategies in the treatment of schizophrenia. It is hoped that the initiation of personalized medicine strategies, such as stratification and using a clinical staging approach, will make it possible to identify the subgroups of patients who can obtain maximum benefit from dietary and nutritional interventions. PMID- 29171644 TI - Nutritional supplements in eating disorders. AB - Eating disorders (EDs) are a series of differentiated nosological entities sharing the common link of a continuous alteration in food intake or in food intake-related behavior. Within this classification, the following disorders are noteworthy: anorexia nerviosa (AN) and bulimia nerviosa (BN). Anorexia nervosa is a chronic disorder characterized mainly by negative or decreased food intake accompanied by a distortion of body image and intense accompanying fear of weight gain. The estimated vital prevalence of this disorder in adolescence is approximately 0.5%-1%.1 The primary feature of BN is the presence of binge eating accompanied by compensatory behavior (in the form of intense exercise and the use of laxatives and diuretics, etc.). The prevalence of BN is estimated to be between 2% and 4% in young women, and it generally starts at somewhat later stages than AN. It is believed that biological, psychological, and environmental factors, as well as genetic vulnerability, influence the pathogenesis of EDs. A variety of therapies exist, both biological and psychological, whose effectiveness is supported by the scientific literature. Nonetheless, we find these therapies only partially effective and new targets as well as new treatments should be sought. Although the etiopathogenesis of EDs is unclear, some of the neurobiological dysfunction found suggests that diet and nutrient supplementation could be relevant in their treatment. We review in this article new treatments focusing on nutritional deficits. PMID- 29171645 TI - Cardiovascular risk factors and white matter hyperintensities in patients with migraine without aura. AB - OBJECTIVES: White matter hyperintensities (WMHs) are observed in patients with migraine with aura (MWA) and without aura (MWO), but there are a limited number of studies regarding patients with MWA. In this study, we aimed to investigate the cardiovascular risk factors which may play a role in the development of WMHs in patients with MWO. METHODS: This observational, analytical, case-control study was conducted between June 2016 and January 2017. It included 21 patients with MWO who had WMHs on brain MRI and 19 patients with MWO who tested normal on MRI (control group) at the Neurology Department Outpatient Polyclinic, Ankara Training and Research Hospital. The patients' data (history, family history, neurological examination findings, echocardiography findings, and cerebral MRI findings) were retrospectively reviewed. RESULTS: Age, gender, body mass index, blood lipid level, migraine duration, localization of headache, average number of headache per month, medication for headache attack, and echocardiography findings were similar between the two groups. (p>0.05). CONCLUSION: In this study, we did not find any association between cardiovascular risk factors and WMHs development in patients with MWO. The association of risk factors other than cardiovascular risk factors (genetic factors and oxidative stress) with the development of WMHs in patients with MWO should also be studied in future. PMID- 29171646 TI - [Effect of rocuronium administration rate and remifentanil on prevention of rocuronium injection pain in pediatric cases]. AB - OBJECTIVES: In this study, we aimed to determine the effect of remifentanil administration prior to slow and fast rocuronium infusion on hemodynamic changes and rocuronium injection pain in pediatric patients. METHODS: In total, 120 5-15 year-old ASA score I/II pediatric patients were included in the study. Group A: slow rocuronium injection-saline; group B: slow rocuronium injection (0.6 mg/kg IV)-remifentanyl; group C: fast rocuronium injection-saline; and group D: fast rocuronium injection-remifentanyl. Withdrawal movement after rocuronium injection was recorded based on a 3-point response to withdrawal score. Hemodynamic parameters were recorded. RESULTS: One minute after rocuronium injection, HR values were found to be lower in remifentanil groups (p: 0.0001; 101.4+/-22.1, p: 0.003; 99.8+/-18.3 in group B and D, respectively) compared with those in placebo groups (p: 0.025; 107.4+/-21.7, p: 0.012; 114.0+/-16.4 in group A and C, respectively). With respect to the response to withdrawal scores, unresponsiveness rates were the highest in group B (66.7%) and group D (70%). The number of non-responder patients was 9 in saline-administered groups (group A and C), whereas it was 20 and 21 in remifentanil-administered groups (group B and D, respectively). Generalized responses were observed predominantly in groups A (20%) and C (20%). Generalized responses were highest in groups A (20%, n=6) and C (20%, n=6). CONCLUSION: There was no impact of infusion speed on rocuronium injection pain in pediatric cases, whereas it is concluded that remifentanil administration prior to rocuronium injection considerably reduced rocuronium injection pain regardless of injection speed and without serious hemodynamic changes. PMID- 29171647 TI - Pain, anxiety, and depression during bone marrow aspiration and biopsy. AB - OBJECTIVES: This study is performed with the aim of prospectively analyzing the factors that affect pain, anxiety, and depression in cases for whom bone marrow aspiration and biopsy are performed and the relationships among them. METHODS: This study consisted of 90 patients who consulted to Department of Hematology, Faculty of Medicine, Uludag University, and followed-up for bone marrow aspiration and biopsy indication. The data was gathered using a personal information form, Hospital Anxiety Depression scale, and Wong-Baker face pain scale where generally face expressions exist. RESULTS: The average age of the patients who participated in the study was 50.90 years (16.59), and the pain level after the application was 1.98 (1.33). After the application, a positive relationship is determined between the pain level and anxiety (r=-0.79; p=0.02), whereas this has a negative relationship with age (r=0.78; p=0.03). CONCLUSION: As a result, pain develops depending on bone marrow aspiration and biopsy; therefore, taking precautions aimed at alleviating pain and evaluation of pain before and after the application within the scope of total maintenance have been suggested. PMID- 29171648 TI - Methemoglobinemia incidence after the application of lidocaine for small surgical procedures. AB - OBJECTIVES: Methemoglobinemia (MetHb) is a rare condition that may have mortal consequences. Literature shows cases of methemoglobinemia due to the use of lidocaine and other local anesthetics. This is a cross-sectional study to determine the incidence of methemoglobinemia after the application of lidocaine. METHODS: In this study, 88 patients admitted to the emergency department of a university hospital between May 2014 and May 2015 and needed lidocaine application for small surgical procedures were included. When compared before and after the administration of lidocaine <2 mg/kg and >2 mg/kg, there was not a significant difference in the level of methemoglobin, hemoglobin, or in the hematocrit (p=0.604, p=0.502, and p=0.367, respectively). RESULTS: Mean age of the patients was 33.85 (+/-17.58) years, and 83% of the patients were male. Methemoglobin levels were not significantly different before and after the procedures (p>0.05). CONCLUSION: The results of our study were consistent with the literature; lidocaine associated methemoglobinemia is a rare complication. PMID- 29171649 TI - [Cognitive behavioral therapy for tension-type headache: a case report]. AB - Tension-type headache has a very high socioeconomic impact, and its lifetime prevalence is reported to be between 30% and 78% in different studies. It is widely acknowledged that noninvasive management with a multidisciplinary approach should be considered for the treatment of tension-type headache. Cognitive behavioral therapy and relaxation exercises are efficient techniques. This article illustrates the application of a cognitive behavioral therapy protocol enhanced with progressive muscle stretching and relaxation exercises in the treatment of chronic tension-type headache via a case report. Our patient had an ongoing headache for 6 years when he was referred to us by the department of psychiatry. After 10 cognitive behavioral therapy sessions, the patient had learned to notice muscle tension and relax the muscles as well as to recognize and express his emotions in a better way. He became aware of automatic thoughts and learned to find alternative thoughts. Headache severity decreased, and he was able to increase participation in daily life activities. PMID- 29171650 TI - [Contact lenses as a migraine trigger]. AB - We aimed to investigate the relationship between contact lens (CL) usage and migraine attacks. Our patient who began using CL with different base curves experienced discomfort and burning of the eyes. The ocular complaints were followed by migraine attacks. The frequency of migraine attacks decreased significantly when the flatter base curve was selected. We assessed the potential causal relationship between CL and migraine. PMID- 29171651 TI - Pulmonary embolism occurring in a patient treated with spinal cord stimulation. AB - Spinal cord stimulation (SCS) has been shown to be an effective method for treating many chronic pain syndromes. In addition, providing pain relief with SCS can reduce immobilization and complications related to immobilization. The present case describes pulmonary embolism (PE) that occurred in patient being treated with SCS for post-laminectomy syndrome. The possibility of PE must be kept in mind while treating patients with SCS. PMID- 29171652 TI - Accidental intrathecal catheterization in two patients having undergone lumbar radiotherapy. PMID- 29171653 TI - Retrospective evaluation of the effects of periprostatic local anesthesia on recurrent prostate biopsy. AB - OBJECTIVES: The aim of the study was investigate the pain palliation effect of 2% dose of lidocaine on the periprostatic nerve block in prostate biopsy patients. METHODS: Extended (12 cores) and saturation (22 cores) biopsy patients were included. The patients were separated into three groups: extended biopsy patients (Group I), saturation biopsy patients (Group II), and control group patients undergoing a biopsy procedure for the first time (Group III). All patients received 2% lidocaine (10 mL) on both the seminal vesicular junction and apex of the prostate with transrectal ultrasonography guidance. Following the procedure, the pain levels of patients were assessed using a 10-cm linear Visual Analog Scale (VAS). RESULTS: Following the procedure, the VAS values of each group were 2.96+/-1.06, 3.2+/-1.47, and 2.93+/-0.94, respectively (p>0.05). While the highest pain score was seen in the saturation group patients (II), the lowest pain level was seen in the control biopsy group (III). However, no statistical di erence was observed among the groups. CONCLUSION: Herein, we observed that a local injection using 2% lidocaine was effective as local anesthetic in recurrent prostate biopsies. In addition, it was found that the pain level increases as the number of cores taken in recurrent prostate biopsies increases; however, this has not been established statistically. PMID- 29171654 TI - Remodelling of collagen fibres in the placentas of women with venous insufficiency during pregnancy. AB - Haemodynamic changes produced during pregnancy lead to elevated venous pressure in the legs and an increased resting consumption of oxygen. These events can cause varicose veins, or venous insufficiency (VI), which by creating an environment of hypoxia could affect the structure and function of the placental barrier. This study assesses the remodelling state of the placental villi by examining differences in collagens with a known role in villus structure and in placental barrier permeability between patients with and without VI. Samples of 67 placentas from women with VI (n=24) and without VI (n=43) during their pregnancy were processed for gene and protein expression analysis of COL-I, COL III, MMP-2 and MMP-9 by RT-qPCR and immunohistochemistry. While no differences in COL-I expression levels were detected in the samples from women with and without VI, significant differences did emerge in both gene and protein expression levels of COL-III. Importantly, COL-I/III ratios were reduced in the VI group compared to controls. MMP-2 activity was similar in the two groups while MMP-9 levels were significantly elevated in VI with greatest expression differences observed at the level of the decidual cells. Mothers who developed VI during pregnancy showed significantly higher COL-III and MMP-9 levels consistent with a state of remodelling of the placental villi. PMID- 29171656 TI - Investigation of the presence of HPV on KTP laser fibers following KTP laser treatment of papilloma. AB - OBJECTIVES: Recurrent respiratory papillomatosis is often treated with in-office laser procedures using a potassium titanyl phosphate (KTP) laser transmitted through a laser fiber. Although effective, this procedure has notable downsides, including the possibility of transmitting human papillomavirus (HPV) in the smoke plume and the high cost of these single-use fibers. The objective of this study is to determine if HPV can be detected on a laser fiber after use, with or without sterilization. METHODS: Twelve patients with laryngeal papillomas were treated with KTP laser energy transmitted via a KTP fiber. Ten fibers were sterilized in CIDEX (ASP, Irvine, California), a glutaraldehyde disinfectant, for 12 minutes, whereas two fibers were left unsterilized. Human papillomavirus DNA amplification was done on all 12 fiber samples with real-time polymerase chain reaction (PCR) using general primer mediated 5+ and 6+. Human papillomavirus genotyping detection was done using type specific probes and/or Sanger sequencing. RESULTS: Over 27 strains of HPV were not detected on KTP fibers after use, with or without sterilization. CONCLUSION: Human papillomavirus was undetectable by PCR on KTP laser fibers that were sterilized or unsterilized after use. Further studies are needed utilizing a transmission model to determine if HPV can be incubated from this fiber after sterilization. LEVEL OF EVIDENCE: NA. Laryngoscope, 128:926-928, 2018. PMID- 29171655 TI - Oral sampling methods are associated with differences in immune marker concentrations. AB - OBJECTIVE: To determine whether the concentration and distribution of immune markers in paired oral samples were similar. STUDY TYPE: Clinical research. STUDY DESIGN: Cross-sectional study. METHODS: Paired saliva and oral secretions (OS) samples were collected. The concentration of immune markers was estimated using Luminex multiplex assay (Thermo Fisher Scientific, Waltham, MA). For each sample, the concentration of respective immune markers was normalized to total protein present and log-transformed. Median concentrations of immune markers were compared between both types of samples. Intermarker correlation in each sampling method and across sampling methods was evaluated. RESULTS: There were 90 study participants. Concentrations of immune markers in saliva samples were significantly different from concentrations in OS samples. Oral secretions samples showed higher concentrations of immunoregulatory markers, whereas the saliva samples contained proinflammatory markers in higher concentration. CONCLUSION: The immune marker profile in saliva samples is distinct from the immune marker profile in paired OS samples. LEVEL OF EVIDENCE: 2b. Laryngoscope, 128:E214-E221, 2018. PMID- 29171657 TI - The parenthood argument. AB - Don Marquis is well known for his future like ours theory (FLO), according to which the killing beings like us is seriously morally wrong because it deprives us of a future we can value. According to Marquis, human fetuses possess a future they can come to value, and thus according to FLO have a right to life. Recently Mark Brown has argued that even if FLO shows fetuses have a right to life, it fails to show that fetuses have a right to use their mother's body, evoking Judith Jarvis Thomson's famous violinist case. In the wake of Brown's conclusion, Marquis presents a new argument-the parenthood argument (PA)-which he believes shows that abortion is seriously morally wrong. Here I argue that the PA fails to show abortion is seriously morally wrong for the same reasons FLO fails to show abortion is seriously morally wrong. PMID- 29171658 TI - Epistaxis in children and adolescents with hereditary hemorrhagic telangiectasia. AB - OBJECTIVES/HYPOTHESIS: Our objective was to describe epistaxis onset and severity in pediatric hereditary hemorrhagic telangiectasia (HHT) patients and study the cumulative incidence of epistaxis by age of onset within each genetic subtype. STUDY DESIGN: Retrospective cohort chart review. METHODS: Charts were reviewed of patients age 0 to 18 years with a clinical or genetic diagnosis of HHT who were evaluated at a tertiary multidisciplinary HHT clinic from January 2010 to June 2016. The epistaxis severity score (ESS), a validated tool for assessing epistaxis severity, was used to assess epistaxis. Statistical analyses were conducted on the full HHT cohort as well as subgroups stratified by the HHT causative gene (HHT1 = ENG and HHT2 = ACVRL1). RESULTS: Sixty-nine pediatric subjects were identified; 60 had HHT confirmed by genetic testing, and nine (from families with known mutations) met published clinical diagnostic criteria alone. Fifty-nine (85%) had onset of epistaxis. The median age of onset of epistaxis was 5 years (interquartile range [IQR]: 2-9 years). The median ESS for the entire cohort was 1.6 (IQR: 0-2.6). The median ESS was higher in HHT1 versus HHT2 (2.3 vs. 1.1, P = .002), and age of epistaxis onset was earlier in HHT1 (3 vs. 5 years, P = .03). Sex and age were not associated with ESS. CONCLUSIONS: Epistaxis may present early in HHT, but is typically mild in the pediatric period. Severity in the pediatric population is worse in patients with HHT1. By recognizing the significance of even mild, infrequent epistaxis in a child with a family history of HHT, and understanding that not all HHT patients have epistaxis during childhood, community providers and otolaryngologist can assist in the early detection of HHT.

AB - In a recent article in this journal, Savulescu and Schuklenk defend and extend their earlier arguments against a right to medical conscientious objection in response to criticisms raised by Cowley. I argue that while it would be preferable to be less accommodating of medical conscientious than many countries currently are, Savulescu and Schuklenk's argument that conscientious objection is 'simply unprofessional' is mistaken. The professional duties of doctors should be defined in relation to the interests of patients and society, and for reasons set out in this article, these may support limited accommodation of conscientious objection on condition that it does not impede access to services. Moreover, the fact that conscientious objection appears to involve unjustifiable compromise from the objector's point of view is not a reason for society not to offer that compromise. Arguing for robust enforcement of the no-impediment condition, rather than opposing conscientious objection in principle, may be a more effective way of addressing the harms resulting from an over-permissive conscientious objection policy. PMID- 29171661 TI - A randomised controlled trial comparing high-flow nasal oxygen with standard management for conscious sedation during bronchoscopy. AB - Traditional conscious sedation for endobronchial ultrasound procedures places patients at risk of desaturation, and high-flow nasal oxygen may reduce the risk. We designed a parallel-group randomised controlled trial of high-flow nasal oxygen at a flow rate of 30-70 l.min-1 via nasal cannulae, compared with standard oxygen therapy at 10 l.min-1 via a bite block in adults planned for conscious sedation for endobronchial ultrasound. The primary outcome was the proportion of patients experiencing desaturation (defined as SpO2 < 90%). Secondary outcomes included oxygen saturation after pre-oxygenation, lowest oxygen saturation during procedure, number of hypoxic episodes, duration of hypoxia, end-procedure end tidal CO2 , satisfaction scores and complications. Thirty participants were allocated to each group. Baseline patient characteristics, procedure time and anaesthetic agents used were similar between the groups. Desaturation occurred in 4 out of 30 patients allocated to the high-flow nasal oxygen group, compared with 10 out of 30 allocated to the standard oxygenation group, a non-significant difference (p = 0.07) with intention to treat analysis. The difference was significant (p = 0.047) when using a per-protocol analysis. Oxygen saturation after pre-oxygenation and the lowest oxygen saturation during procedure were significantly higher in the high-flow nasal oxygen group compared with the standard oxygenation group; median (IQR [range] 100 (99-100 [93-100]) vs. 98 (97 99 [94-100]), p = 0.0001 and 97.5 (94-99 [77-100]) vs. 92 (88-95 [79-98]), p < 0.001, respectively. There were no differences in other secondary outcomes. Although high-flow nasal oxygen may prevent desaturation due to some causes, it does not protect against hypoxaemia in all circumstances. PMID- 29171660 TI - Relationship between degree of obstruction and airflow limitation in subglottic stenosis. AB - OBJECTIVES: Subglottic stenosis (SGS) is one of the most common airway disorders in pediatric patients. Currently, treatment decisions rely primarily on the Cotton-Myer scale, which classifies SGS severity based on percentage reduction in airspace cross-sectional area (CSA). However, the precise relationship between upper airway resistance and subglottic CSA is unknown. We hypothesize that airway resistance can be described by the Bernoulli Obstruction Theory, which predicts that airway resistance is inversely proportional to airspace CSA ( R?A-1) in cases of severe constriction. METHODS: Computed tomography (CT) scans of six healthy subjects and five SGS patients were used to create three-dimensional models of the respiratory tract from nostrils to carina. Cylindrical segments of varying lengths and varying diameters were digitally inserted in the subglottis of the healthy subjects to create simulated SGS models. Computational fluid dynamics simulations were run, and airway resistance was computed in the simulated SGS models and actual SGS models. RESULTS: Constriction diameter had a greater impact in airway resistance than constriction length. In agreement with the Bernoulli Obstruction Theory, airway resistance in the simulated SGS models was well represented by the power law R=aAb, where a is a constant and the exponent b ranged from -0.85 to -1.07. The percentage reduction in airflow (QOBSTRUCTIONQHEALTHY) at a constant pressure drop was found to be directly proportional to the percentage reduction in CSA (AOBSTRUCTIONAHEALTHY) in the limit of severe constrictions, namely QOBSTRUCTIONQHEALTHY=kAOBSTRUCTIONAHEALTHY, where k=2.25 +/- 0.15. Airway resistances in the simulated SGS models were similar to resistances in models based on CT scans of actual SGS patients, suggesting that our simulated SGS models were representative of airway resistance in actual SGS patients. CONCLUSION: Our computer simulations suggest that the degree of airflow limitation in SGS patients may be estimated based on anatomic measurements alone. Future studies are recommended to test these predictions in larger cohorts. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:1551-1557, 2018. PMID- 29171662 TI - A Within-Family Examination of Interparental Conflict, Cognitive Appraisals, and Adolescent Mood and Well-Being. AB - Interparental conflict (IPC) is a well-established risk factor across child and adolescent development. This study disentangled situational (within-family) and global (between-family) appraisal processes to better map hypothesized processes to adolescents' experiences in the family. This 21-day daily dairy study sampled 151 caregivers and their adolescents (61.5% female). Using multilevel mediation analyses indicated that, on days when IPC was elevated, adolescents experienced more threat and self-blame. In turn, when adolescents experienced more threat appraisals, they experienced diminished positive well-being; whereas days when adolescents felt more self-blame, they experienced increased negative mood and diminished positive well-being. Statistically significant indirect effects were found for threat as a mediator of IPC and positive outcomes. Daily blame appraisals mediated IPC and adolescent angry mood. PMID- 29171663 TI - Granulocytic anaplasmosis in 63 dogs: clinical signs, laboratory results, therapy and course of disease. AB - OBJECTIVES: To describe the clinical signs, laboratory results, therapy and course of disease in dogs with canine granulocytic anaplasmosis in which co infections had been excluded. METHODS: Medical records of dogs naturally infected with Anaplasma phagocytophilum were retrospectively evaluated with regard to clinical signs and laboratory abnormalities at the time of presentation, therapy and course of disease. RESULTS: Nine hundred and seventy-four dogs with clinical signs suspicious for canine granulocytic anaplasmosis were tested for A. phagocytophilum DNA by modified real-time PCR; 72 dogs had a positive result. Nine of the positive dogs were excluded from further evaluation due to other diseases or lack of data. The most common clinical signs in the 63 A. phagocytophilum-positive dogs included in the study were lethargy and reduced activity (83%), fever (67%) and inappetence (63%). Thrombocytopenia was the most common laboratory abnormality (86%), followed by increased liver enzyme activities and hyperbilirubinaemia (77%), anaemia (70%), hypoalbuminaemia (62%) and leucocytosis (27%). Of 36 thrombocytopenic dogs tested for platelet-bound antibodies, 44% were positive. Of the 63 infected dogs, 59 (97%) recovered, two dogs died (epileptic seizures and immune-mediated haemolytic anaemia) and two were lost to follow-up. CLINICAL SIGNIFICANCE: In areas where it is endemic, canine granulocytic anaplasmosis should be considered as a potential cause of acute nonspecific clinical signs or immune-mediated disease if tick exposure cannot be excluded. PMID- 29171664 TI - Does water fluoridation affect the prevalence of enamel fluorosis differently among racial and ethnic groups? AB - OBJECTIVES: There are reports showing higher prevalence of enamel fluorosis among African-American children. This study was conducted to assess whether the effect of water fluoride level on enamel fluorosis is different among different race/ethnicity groups among US school children. METHODS: Data from the National Survey of Oral Health of US School Children 1986-1987 were analyzed to determine the prevalence of enamel fluorosis among 7-17 year-old children. The association between race/ethnicity and enamel fluorosis was examined using logistic regression modeling after controlling for potential confounders age, gender, water fluoridation, other sources of fluoride, and region of residence. RESULTS: The prevalence of very mild to severe enamel fluorosis was 20.8 (95% CI, 15.4, 26.3) and 25.7 (95% CI, 15.0, 36.5) percent among non-Hispanic White and non Hispanic Black children, respectively. Neither the adjusted odds ratio of 1.3 (0.8, 2.0) for the non-Hispanic Black group nor the interaction effect between non-Hispanic Black and water fluoridation were statistically significant. CONCLUSIONS: Enamel fluorosis was not associated with race/ethnicity. Our analysis suggests that exposure to similar levels of fluoride in the water does not appear to place certain race/ethnic groups at a higher risk for developing enamel fluorosis, and lowering the optimal range of drinking water fluoride to a single value of 0.7 ppm will provide a level of protection against enamel fluorosis that will benefit all race/ethnicity groups.

PMID- 29171666 TI - The association between paternal depressogenic cognitive styles during pregnancy and offspring depressogenic cognitive styles: an 18-year prospective cohort study. AB - BACKGROUND: Preventing the development of depressogenic or negative cognitive styles could also prevent the development of depression, a leading public health problem worldwide. Maternal negative cognitive styles are a modifiable risk factor for the development of negative cognitive styles in offspring. However, evidence on the role of paternal negative cognitive styles is inconclusive and there have only been a few small studies, which may also have lacked statistical power. METHODS: We used data from the Avon Longitudinal Study of Parents and Children (ALSPAC) to investigate the association between paternal negative cognitive styles, measured when mothers were 18 weeks pregnant, and offspring negative cognitive styles 18 years later (N = 6,123). Associations were calculated using linear regression models, before and after adjustment for confounders including maternal negative cognitive styles. We compared associations before and after controlling for depression in parents and offspring, and used multiple imputation to reduce biases that may have arisen due to missing data. RESULTS: A two-standard deviation increase in paternal negative cognitive style was associated with a 3-point increase in offspring negative cognitive style (95% CI 1.36-4.37). This association remained after adjustment for confounders and was independent of depression in both parents and offspring. The effect size was equivalent to that of maternal negative cognitive style, and was also independent of maternal negative cognitive style. CONCLUSIONS: Our results suggest that fathers should be included in individual- and family-based interventions designed to prevent the development of depressogenic cognitive styles in adolescent offspring. This could possibly also prevent the development of depression. PMID- 29171667 TI - Exposure to Parental Depression in Adolescence and Risk for Metabolic Syndrome in Adulthood. AB - The psychosocial consequences of living with a depressed parent have been well characterized. Less well known, however, is how this exposure is predictive of later physical health problems. The present study evaluated how parental depression across youths' adolescence (ages 11-18) was associated with youth metabolic syndrome at age 25 (n = 391). Youth self-regulation and health behaviors were considered as possible moderators of the link between parental depression and youth metabolic syndrome. Analyses revealed that parental depression in adolescence was associated with a composite score reflecting metabolic syndrome components in early adulthood. Furthermore, self-regulation and health behaviors moderated this link, such that links between parental depression and the metabolic syndrome existed only for youth with low self regulation or unhealthy behaviors. PMID- 29171668 TI - Post-temporary ligation intraoperative mesenteric portovenography: comparison with CT angiography for investigation of portosystemic shunts. AB - OBJECTIVES: Comparison of pre-operative CT angiography and post-temporary, full ligation, intraoperative, mesenteric portovenography for the characterisation of intrahepatic portal vasculature in patients with single extrahepatic portosystemic shunts. METHODS: Descriptive analysis of previously collected images from 14 dogs and five cats. RESULTS: With the exception of shunts involving the right gastric vein, intrahepatic arborisation appeared similar on both modalities. Portovenography improved contrast enhancement and slightly enlarged the intrahepatic portal vasculature. CLINICAL SIGNIFICANCE: CT angiography cannot replace intraoperative mesenteric portovenography after temporary full ligation, which provides information on intrahepatic portal vascularity. It is a practical and dynamic procedure, providing results that are instantaneously available at the time of surgery. In addition, intraoperative post-temporary, full-ligation, mesenteric portography confirmed that the single shunting vessel had both been recognised and ligated.

Values for cardiac output, mean arterial and central venous pressure, and the calculated cardiovascular variables mean systemic filling pressure analogue, heart efficiency, cardiac power indexed by volume state and volume efficiency, before and after passive leg raising as well as before and after fluid volume challenge, were extracted from published studies. Eleven studies including 572 patients and 52% responders were analysed. Cardiac output increased by 12% in responders during passive leg raising and by 22% following a volume challenge. No statistically significant differences were found between responders and non responders in cardiac output, mean arterial or central venous pressure before the passive leg-raising manoeuvre or the volume challenge. In contrast, the calculated mean (SD) systemic filling pressure analogue, reflecting the intravascular volume, was significantly lower in responders (14.2 (1.8) mmHg) than non-responders (17.5 (3.4) mmHg; p = 0.007) before the passive leg-raising manoeuvre, as well as before fluid volume challenge (14.6 (2.2) mmHg vs. 17.6 (3.5) mmHg, respectively; p = 0.02). The scalar measure volume efficiency was higher in responders at 0.35 compared with non-responders at 0.10. Non-responders also demonstrated deteriorating heart efficiency of -15% and cardiac power of -7% when given an intravenous fluid volume challenge. The results demonstrate that the calculation of mean systemic filling pressure analogue and derived variables can identify patients likely to respond to a fluid volume challenge and provides scalar results rather than merely a dichotomous outcome of responder or non responder.

AB - OBJECTIVES/HYPOTHESIS: Pirfenidone (PFD) is a strong antifibrotic agent that has been clinically approved in Japan for idiopathic pulmonary fibrosis. We examined the antifibrotic effects of PFD on fibroblasts isolated from scarred vocal folds (VFs) of ferrets in vitro. STUDY DESIGN: Prospective animal experiments with controls. METHODS: Scar fibroblasts (SFs) were isolated from scarred VFs that had been electrocauterized 2 weeks before harvesting (N = 4). Normal fibroblasts (NFs) were isolated from intact VFs (N = 4). SFs and NFs were incubated in the presence of 10 ng/mL transforming growth factor beta1 (TGF-beta1), with or without PFD. After the 48-hour incubation, mRNA expression levels of alpha smooth muscle actin (alphaSMA), TGF-beta1, collagen type I, and hyaluronan synthase 2 (HAS2) were examined by real-time polymerase chain reaction. Immunohistochemistry with anti-alphaSMA anti-collagen type I and phosphorylated Smad (p-Smad)2/3 antibodies in SFs with or without PFD was performed. SFs and NFs were cultured in collagen gel with or without PFD for 48 hours, and the extent of gel contraction was examined quantitatively. RESULTS: PFD treatment significantly (P < .05) decreased mRNA expression of collagen type I, significantly increased mRNA expression of TGF-beta1 and HAS2, and significantly suppressed collagen gel contraction. However, it did not have a significant effect on the expression of alphaSMA. The expression of p-Smad2/3 in the nucleus was faded with PFD, possibly demonstrating the suppression of translocation of p-Smad2/3 from cytoplasm to nucleus with PFD. CONCLUSIONS: This is the first report to demonstrate the in vitro antifibrotic effects of PFD on fibroblasts isolated from scarred VFs of ferrets. LEVEL OF EVIDENCE: NA.

AB - OBJECTIVE: Many trials incorporate induction chemotherapy (IC) in selecting for organ preservation in head and neck squamous cell carcinomas (HNSCC). However, few studies examine IC response in predicting for chemoradiation therapy (CRT) response. This meta-analysis aims to determine the predictive accuracy of IC for subsequent response to CRT and overall survival (OS). DATA SOURCES: Medline, EMBASE, Cochrane register. METHODS: A systematic search identified studies from database inception to October 2016 that used IC prior to CRT as definitive treatment for advanced HNSCC. The sensitivities and specificities of IC response predicting for complete CRT response were calculated, and the results were pooled in a summary receiver operating curve. One-, 2- and 5-year OS data were extracted. RESULTS: Seven studies (n = 423 patients) were analyzed for response and six (n = 439) for OS. Pooled median sensitivity and specificity of IC response predicting CRT response were 0.95 (95% confidence interval [CI]: 0.72 0.98) and 0.43 (95% CI: 0.00-0.61), respectively. Patients were more likely to respond to CRT given previous response to IC (positive likelihood ratio = 1.6; 95% CI: 1.21-2.11) and less likely to respond to CRT if they failed to respond to IC (negative likelihood ratio = 0.16; 95% CI: 0.07-0.38). At 2 years, good response to IC was a statistically significant prognostic marker with a risk ratio of 1.35 (95% CI: 1.12-1.64). CONCLUSION: Our data suggests that patients with poor IC response will have poorer response to CRT and should be directed to other modalities. In contrast, good IC response does not guarantee a favorable outcome to CRT; however, because these patients are likely to have better prognoses, they should be offered salvage therapies of curative intent despite treatment failure.

AB - OBJECTIVE: Frontal sinus anatomy is complex and often is a difficult subject to both teach and learn. The traditional surgical dogma of "see one, do one, teach one" is impractical and dangerous in the frontal sinus. Based on the building block three-dimensional conceptualization module, the Frontal Sinus Masterclass (FSMC) was created to teach this anatomy. METHODS: Study was performed at two academic centers among second- to fifth-year otolaryngology residents. A pretest assessed knowledge prior to the course. Computed tomography scans of the sinuses were evaluated in triplanar view, and participants attempted to reconstruct the anatomy. Subsequently, the course instructor explained the anatomy using the building block method and showed a short video of the surgical dissection, pointing out relevant anatomy. Cases progressed in anatomical difficulty and inflammatory load. A posttest determined knowledge after the course. RESULTS: Thirty of 50 participating residents completed the pre- and posttests (14 junior, 16 senior residents). Correct identification of the frontal sinus drainage pathway increased from 42% to 63% correct (P = 0.054). Anatomical assessment increased from 61% to 68% correct (P = 0.047), and overall assessment increased from 52% to 66% correct (P = 0.016). CONCLUSION: Objectively, participants of the FSMC expanded on their ability to recognize cells of the frontal recess on CT scans. Before the class, residents could answer less than half of the answers correctly, and by the end of the class they were answering over two-thirds of these complex questions correctly. Subjectively, participants reported benefit from the course and felt they would be better surgeons. LEVEL OF EVIDENCE: NA. Laryngoscope, 128:1294-1298, 2018. PMID- 29171673 TI - Does the diameter of the stapes prosthesis really matter? A prospective clinical study. AB - OBJECTIVES/HYPOTHESIS: To evaluate the influence of the diameter of stapes prosthesis on functional outcomes in stapes surgery. STUDY DESIGN: Prospective cohort study. METHODS: Fifty consecutive small fenestra stapedotomies performed using a 0.4-mm-diameter prosthesis were compared with 50 consecutive small fenestra stapedotomies carried out using a 0.6-mm-diameter piston. Audiological assessment following the recommendations of the Committee on Hearing and Equilibrium was performed 1 month after surgery. Postoperative complications between the two groups were noted. RESULTS: There were no statistically significant differences in demographic data between the two groups, and no differences in preoperative bone-conduction (BC) or air-conduction (AC) hearing thresholds for all frequencies (analysis of variance [ANOVA] and chi2 tests). No differences were found in the mean preoperative BC and AC pure-tone average and air-bone gap (ABG). In the postoperative evaluation, a statistically significant difference was found for the mean AC gain (20 +/- 8.7 vs. 24 +/- 11.5, P = .042, ANOVA) as well as for the postoperative AC threshold at 0.125 and 0.25 kHz and the postoperative BC threshold at 0.25 kHz (P < .01, ANOVA). A postoperative ABG <=10 dB was obtained in 90% and 94% of patients in the 0.4-mm- and 0.6-mm diameter piston groups, respectively (difference not significant, chi2 test). No postoperative dead ear and/or sensorineural hearing loss was noted in either group. CONCLUSIONS: The 0.6-mm piston allowed a statistically significant higher AC gain compared with the 0.4-mm diameter piston. A larger diameter piston may be preferable if there are no anatomical or technical reasons that would favor a smaller prosthesis. LEVEL OF EVIDENCE: 2b Laryngoscope, 1922-1926, 2018. PMID- 29171674 TI - A dubious defense of 'after-birth abortion': A reply to Rasanen. AB - Scholars have offered various critiques of Alberto Giubilini and Francesca Minerva's controversial article, 'After-birth abortion: Why should the baby live?' My book The Ethics of Abortion: Women's Rights, Human Life, and the Question of Justice presents four such critiques. First, Giubilini and Minerva argue from the deeply controversial to the even more controversial. Second, they presuppose a false view of personal identity called body-self dualism. Third, their view cannot secure human equality. And fourth, their account of harm cannot account for harm found in some cases of murder. In the article, 'Pro-life arguments against infanticide and why they are not convincing', J. Rasanen examines and finds wanting these four critiques. This essay responds to Rasanen's defense of infanticide and argues that his responses to the four objections fail. PMID- 29171675 TI - Judgments of moral responsibility in tissue donation cases. AB - If a person requires an organ or tissue donation to survive, many philosophers argue that whatever moral responsibility a biological relative may have to donate to the person in need will be grounded at least partially, if not entirely, in biological relations the potential donor bears to the recipient. We contend that such views ignore the role that a potential donor's unique ability to help the person in need plays in underwriting such judgments. If, for example, a sperm donor is judged to have a significant moral responsibility to donate tissue to a child conceived with his sperm, we think this will not be due to the fact that the donor stands in a close biological relationship to the recipient. Rather, we think such judgments will largely be grounded in the presumed unique ability of the sperm donor to help the child due to the compatibility of his tissues and organs with those of the recipient. In this paper, we report the results of two studies designed to investigate the comparative roles that biological relatedness and unique ability play in generating judgments of moral responsibility in tissue donation cases. We found that biologically related individuals are deemed to have a significant moral responsibility to donate tissue only when they are one of a small number of people who have the capacity to help.

AB - Sociocultural models of body image posit that the media and peers play a role in early adolescents' body dissatisfaction. Introducing a sociocultural perspective on youth sexualization, the present three-wave panel study (N = 968, Mage = 11.30) sought to examine the role of tween television and peer appearance conversations in early adolescents' body surveillance and self-objectification over time. Special attention was given to the mediating role of media internalization in these relationships. The results showed evidence for a reciprocal interaction between media internalization and peer appearance conversations and identified this reciprocal interaction as the underlying mechanism linking tween television exposure to higher levels of body surveillance and self-objectification 1 year later. Implications for body image and media literacy programs are discussed.

AB - AIM: This retrospective study examined the clinical presentation and outcome of all patients who presented with acute kidney injury (AKI) following consumption of uncooked fish gallbladder as folk medicine. METHODS: We reviewed all cases admitted at our institute between 1st January 1997 and 31st December 2016 following ingestion of fish gallbladder (Indian carp/Labeo rohita). RESULTS: A total 32 of patients were included, with a male: female ratio of 3:1 and mean age 44.34 +/- 13.33 years. The mean number of gall bladder consumed was 4.59+/-4.75. All 32 patients presented with hepatic and renal failure. The mean duration of onset of symptoms following ingestion was 6.47+/-2.84 hours. At the time of admission, urine output was 187.9+/-141 ml/24 hours, serum creatinine 11.66+/ 2.50 mg/dl, serum bilirubin 6.14+/-3.91 mg/dl, SGPT 687+/-458 IU/L and SGOT 188+/ 181 IU/L. All but one patient required hemodialysis. Twenty-seven patients were discharged with recovering acute kidney injury while 5 patients died. Mean duration of hospital stay was 12.94+/-8.31 days. Mean number of hemodialysis received by patients was 4.59+/-3.12. Interval between consumption and onset of symptoms, serum bilirubin and SGPT were found to be significantly different between those who survived and died. CONCLUSION: AKI associated with ingestion of raw fish gallbladder is associated with significant morbidity and mortality. PMID- 29171678 TI - Visibility and meanings of partnership in health care for older people who need support to live at home. AB - INTRODUCTION: Problems experienced by older people with complex needs to live at home have been reported in the literature. This qualitative study builds on previous research and investigates enduring issues older people face when interacting with healthcare services. AIM: To gain an in-depth understanding of what is involved in providing good quality health care for older people who need support to live at home. METHODOLOGICAL DESIGN: We adopted an interpretive descriptive approach and conducted semi-structured interviews with older people (n = 7), carers (n = 8) and key informants (n = 11). Initial and secondary analysis of qualitative data was completed. FINDINGS: Major themes emerged about meanings of partnership in health care, and invisibility of the older person as a partner in health care. Partnership in health care was understood to mean being treated as an equal, being involved in decision-making, and making contributions which impact on health care and health systems. The metaphorical concept of 'invisibility' related to the older person not being seen and heard as a partner in health care, as well as being a recipient of care. CONCLUSIONS: We concluded that older people who need support to live at home are not highly visible to health providers, policymakers and researchers as a central partner and consumer to be meaningfully engaged in shaping their health care. Opportunities to address persistent issues with quality of health care may in future be achieved through stronger partnerships between older people and health providers, to find new ways to improve the quality of care for older people. PMID- 29171679 TI - Self-Assembled Hybrid Materials Based on Organic Nanocrystals and Carbon Nanotubes. AB - Organic crystalline materials are used as dyes/pigments, pharmaceuticals, and active components of photonic and electronic devices. There is great interest in integrating organic crystals with inorganic and carbon nanomaterials to create nanocomposites with enhanced properties. Such efforts are hampered by the difficulties in interfacing organic crystals with dissimilar materials. Here, an approach that employs organic nanocrystallization is presented to fabricate solution-processed organic nanocrystal/carbon nanotube (ONC/CNT) hybrid materials based on readily available organic dyes (perylene diimides (PDIs)) and carbon nanotubes. The hybrids are prepared by self-assembly in aqueous media to afford free-standing films with tunable CNT content. These exhibit excellent conductivities (as high as 5.78 +/- 0.56 S m-1 ), and high thermal stability that are superior to common polymer/CNT hybrids. The color of the hybrids can be tuned by adding various PDI derivatives. ONC/CNT hybrids represent a novel class of nanocomposites, applicable as optoelectronic and conductive colorant materials.

AB - For the first time, the bidentate phosphinite ligand 1,2-bis(di-tert butylphosphinoxy)ethane (tBu2 POCH2 CH2 OPtBu2 ) was synthesized. In the presence of this ligand, various N-acyl enamides were obtained in good yields and chemoselectivity by Pd-catalyzed carbonylation reaction of imines containing alpha-H. Meanwhile, imines without alpha-H could be transformed to N-acyl imines, which form highly hindered amides by straightforward addition of Grignard reagents. PMID- 29171681 TI - Spatial Patterning of Hydrogels via 3D Covalent Transfer Stamping from a Fugitive Ink. AB - In this study, a novel hydrogel patterning approach using 3D covalent transfer stamping from a fugitive ink is introduced. A model transfer molecule (7 diethylamino-3-(4'maleimidylphenyl)-4-methylcoumarin (CPM)) is absorbed into a 3D fugitive ink stamp made from poly(caprolactone), and then encapsulated in a poly(ethylene glycol) hydrogel. As the CPM diffuses from the fugitive ink to the curing hydrogel it is selectively covalently bound at the boundary of the ink and the hydrogel. Removal of the fugitive ink by solvent exchange leads to a negative copy of interconnected channels patterned with the localized transfer of the molecules at the hydrogel interface. The results suggest that small molecules can be patterned in porous hydrogels in a spatially controllable manner and that the transferred amount can be tuned.

AB - BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an alternative to surgical aortic valve replacement (SAVR) for patients with severe symptomatic aortic stenosis (AS) who are at intermediate and high risk for surgery. Commercial use of TAVR has expanded to patients with end stage renal disease (ESRD). OBJECTIVES: Compare in-hospital outcomes of TAVR versus SAVR in ESRD patients requiring hemodialysis (HD). METHODS: ESRD patients on HD undergoing TAVR (n = 328) or SAVR (n = 697) between 2012 and 2014 were identified in the National Inpatient Sample (NIS). Propensity-score matching method was used to minimize selection bias. Baseline characteristics and in-hospital outcomes were compared. RESULTS: TAVR patients were older (75.3 vs. 61.6 years, P < 0.001) and had more comorbidities, including congestive heart failure (16.2% vs. 7.5%), diabetes mellitus (28.4% vs. 22.5%), chronic lung disease (27.7% vs. 20.4%), and peripheral vascular disease (35.1% vs. 21.2%). Propensity-score matching yielded 175 pairs of patients matched on 30 baseline covariates. Overall in-hospital mortality was high (9.9%) and similar between TAVR and SAVR (8% vs. 10.3%, P = 0.58). TAVR was associated with shorter length of stay (LOS) (8 vs. 14 days, P < 0.001), lower hospitalization cost ($276,448 vs. $364,280, P = 0.01), lower in hospital complications (60.6% vs. 76%, P = 0.003), and higher rate of home discharge (31.4% vs. 17.7%, P = 0.004) compared with SAVR. CONCLUSIONS: Regardless of treatment modality, patients with AS on HD have high in-hospital mortality. TAVR and SAVR have comparable in-hospital mortality in this population. However, TAVR is associated with shorter LOS, lower hospitalization costs, lower in-hospital complications, and higher rates of home discharge. PMID- 29171683 TI - Ptychographic X-Ray Imaging of Colloidal Crystals. AB - Ptychographic coherent X-ray imaging is applied to obtain a projection of the electron density of colloidal crystals, which are promising nanoscale materials for optoelectronic applications and important model systems. Using the incident X ray wavefield reconstructed by mixed states approach, a high resolution and high contrast image of the colloidal crystal structure is obtained by ptychography. The reconstructed colloidal crystal reveals domain structure with an average domain size of about 2 um. Comparison of the domains formed by the basic close packed structures, allows us to conclude on the absence of pure hexagonal close packed domains and confirms the presence of random hexagonal close-packed layers with predominantly face-centered cubic structure within the analyzed part of the colloidal crystal film. The ptychography reconstruction shows that the final structure is complicated and may contain partial dislocations leading to a variation of the stacking sequence in the lateral direction. As such in this work, X-ray ptychography is extended to high resolution imaging of crystalline samples. PMID- 29171684 TI - Comparison of left atrial pressure monitoring with dedicated catheter versus steerable guiding catheter during transcatheter mitral valve repair. AB - OBJECTIVE: The objective of this study was to determine the accuracy of left atrial pressure (LAP) measurement through the manufacturer provided steerable guiding catheter (SGC) during transcatheter mitral valve repair (TMVR). BACKGROUND: LAP measurement during TMVR has been shown to be associated with clinical improvement when measured through a dedicated catheter. METHODS: Simultaneous LAP was performed in consecutive patients using an independent fluid filled 4F multipurpose catheter and compared to LAP waveforms measured through the manufacturer-provided MitraClip SGC during TMVR (Abbott, Santa Clara, CA). RESULTS: Mean age of 10 consecutive subjects with primary mitral regurgitation undergoing TMVR was 83 +/- 3 years (60% female). Left atrial v wave and mean pressures through the dedicated catheter were 42 +/- 7 and 24 +/- 3 mmHg vs. 35 +/- 7 and 23 +/- 3 mmHg through the SGC (P < 0.001 and P = 0.23, respectively). Mean differences in v wave and mean LAP were 8 +/- 4 and 1.0 +/- 2.4 mmHg (percent difference 19 and 3%), respectively. SGC waveform overdamping was observed in all cases. CONCLUSIONS: Left atrial v wave pressure measurement through a dedicated catheter with sideholes during TMVR has superior accuracy compared to the manufacturer provided SGC, which results in waveform overdamping and a significant underestimation of v wave pressure. These data have important implications for clinical practice. PMID- 29171685 TI - SLC6A3 polymorphism and response to methylphenidate in children with ADHD: A systematic review and meta-analysis. AB - Methylphenidate (MPH) is the most commonly used treatment for attention-deficit hyperactivity disorder (ADHD) in children. However, the response to MPH is not similar in all patients. This meta-analysis investigated the potential role of SLC6A3 polymorphisms in response to MPH in children with ADHD. Clinical trials or naturalistic studies were selected from electronic databases. A meta-analysis was conducted using a random-effects model. Cohen's d effect size and 95% confidence intervals (CIs) were determined. Sensitivity analysis and meta-regression were performed. Q-statistic and Egger's tests were conducted to evaluate heterogeneity and publication bias, respectively. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was used to assess the quality of evidence. Sixteen studies with follow-up periods of 1-28 weeks were eligible. The mean treatment acceptability of MPH was 97.2%. In contrast to clinical trials, the meta-analysis of naturalistic studies indicated that children without 10/10 repeat carriers had better response to MPH (Cohen's d: -0.09 and 0.44, respectively). The 9/9 repeat polymorphism had no effect on the response rate (Cohen's d: -0.43). In the meta-regression, a significant association was observed between baseline severity of ADHD, MPH dosage, and combined type of ADHD in some genetic models. Sensitivity analysis indicated the robustness of our findings. No publication bias was observed in our meta-analysis. The GRADE evaluations revealed very low levels of confidence for each outcome of response to MPH. The results of clinical trials and naturalistic studies regarding the effect size between different polymorphisms of SLC6A3 were contradictory. Therefore, further research is recommended.

AB - The development of highly active electrocatalysts is crucial for the advancement of renewable energy conversion devices. The design of core-shell nanoparticle catalysts represents a promising approach to boost catalytic activity as well as save the use of expensive precious metals. Here, a simple, one-step synthetic route is reported to prepare hexagonal nanosandwich-shaped Ni@Ru core-shell nanoparticles (Ni@Ru HNS), in which Ru shell layers are overgrown in a regioselective manner on the top and bottom, and around the center section of a hexagonal Ni nanoplate core. Notably, the synthesis can be extended to NiCo@Ru core-shell nanoparticles with tunable core compositions (Ni3 Cox @Ru HNS). Core shell HNS structures show superior electrocatalytic activity for the oxygen evolution reaction (OER) to a commercial RuO2 black catalyst, with their OER activity being dependent on their core compositions. The observed trend in OER activity is correlated to the population of Ru oxide (Ru4+ ) species, which can be modulated by the core compositions.

AB - To date, the possible depletion of lithium resources has become relevant, giving rise to the interest in Na-ion batteries (NIBs) as promising alternatives to Li ion batteries. While extensive investigations have examined various transition metal oxides and chalcogenides as anode materials for NIBs, few of these have been able to utilize their high specific capacity in sodium-based systems because of their irreversibility in a charge/discharge process. Here, the mixed Sn-S nanocomposites uniformly distributed on reduced graphene oxide are prepared via a facile hydrothermal synthesis and a unique carbothermal reduction process, producing ultrafine nanoparticle with the size of 2 nm. These nanocomposites are experimentally confirmed to overcome the intrinsic drawbacks of tin sulfides such as large volume change and sluggish diffusion kinetics, demonstrating an outstanding electrochemical performance: an excellent specific capacity of 1230 mAh g-1 , and an impressive rate capability (445 mAh g-1 at 5000 mA g-1 ). The electrochemical behavior of a sequential conversion-alloying reaction for the anode materials is investigated, revealing both the structural transition and the chemical state in the discharge/charge process. Comprehension of the reaction mechanism for the mixed Sn-S/rGO hybrid nanocomposites makes it a promising electrode material and provides a new approach for the Na-ion battery anodes.

This biomimetic account, "focusing on catalytic systems in confinement" within zero-dimensional microenvironments and second sphere coordination covers primarily results from our group on N-sulfonylketenimine mediated cycloaddition, hydrogenation and C-C bond forming reactions, thus providing an interesting insight into the versatility and utility of these Cu and Pd catalysts. Other significant advantages and green credentials of confinement such as stability, selectivity, reusability, promotion of multicomponent reactions, use of green solvents, atom economy, and use of ambient conditions are highlighted at appropriate places. In the final section, our views on the current achievements and the future prospects in this area are summarized. PMID- 29171689 TI - The moderating role of regulatory emotional self-efficacy on smoking craving: An ecological momentary assessment study. AB - Emotion is presumed as a major reason for smoking, but this hypothesis needs support from data with high ecological validity. Regulatory emotional self efficacy (RESE) is key for emotion regulation, therefore RESE is likely to moderate the relationship between emotional states and smoking. The present study used the ecological momentary assessment (EMA) to record the levels of pleasure, arousal, and smoking craving in 33 male current smokers' daily lives, and examined the moderating effect of RESE in the prediction relationship between emotion and craving. The results showed that either end of the pleasure dimension, namely the high positive or high negative affect, predicted higher smoking craving. A similar pattern was also discovered in the arousal dimension, in which either of the activation and deactivation ends predicted higher smoking craving. Moreover, the prediction of negative affect on smoking craving was weakened by higher RESE, especially by the higher self-efficacy in managing negative emotions. In conclusion, smoking craving is closely related with immediate emotional states, and RESE reveals promising value in the reduction of smoking behavior. We discuss the possibility of expanding the RESE frame. PMID- 29171690 TI - Discovery of 2D Anisotropic Dirac Cones.

The Dirac cones are centered at the X and X' points. The data also reveal that the hybridization between borophene and Ag(111) is very weak, which explains the preservation of the Dirac cones. As chi3 borophene has been predicated to be a superconductor, the results may stimulate further research interest in the novel physics of borophene, such as the interplay between Cooper pairs and the massless Dirac fermions. PMID- 29171691 TI - Na-Cation-Assisted Exfoliation of MX2 (M = Mo, W; X = S, Se) Nanosheets in an Aqueous Medium with the Aid of a Polymeric Surfactant for Flexible Polymer Nanocomposite Memory Applications. AB - 2D nanosheets of transition metal dichalcogenides (TMDCs) have been attracting attention due to their sizable band gap. Facile and effective Na-cation-assisted exfoliation of TMDC (MX2 , M = Mo, W; X = S, Se) nanosheets in an aqueous medium and their application as a composite filler in a polyvinyl alcohol (PVA) matrix are explored in this work. The presence of Na cations is highly beneficial for exfoliating defect-free and few-layer MX2 nanosheets in water in the presence of small-sized micelles of polymeric surfactant, and significantly elevates the exfoliation yield by more than one order of magnitude compared to a conventional surfactant-assisted exfoliation. The strategy suggested in this work is very advantageous compared to both Li cation intercalation in organic solvents and conventional low-yield surfactant-assisted exfoliations. As an application of the exfoliated nanosheets, the fabrication of memory devices with the configuration of Ga-doped ZnO/MX2 -PVA/Ag is demonstrated, and they exhibit bistable and write once-read-many-times resistive switching behavior with a high ON/OFF current ratio of 3 * 103 at -1.0 V (for WS2 ) and 2.0 V (for MoS2 ). Furthermore, MX2 PVA nanocomposite fibrous films and mats are successfully fabricated using an electrospinning technique, which can expand the use of TMDC nanofillers in applications involving highly flexible polymer-based MX2 composites.

AB - Dihydropteroate synthase (DHPS) is an enzyme of the folate biosynthesis pathway, which catalyzes the formation of 7,8-dihydropteroate (DHPt) from 6-hydroxymethyl 7,8-dihydropterin pyrophosphate (DHPPP) and para-aminobenzoic acid (pABA). DHPS is the long-standing target of the sulfonamide class of antibiotics that compete with pABA. In the wake of sulfa drug resistance, targeting the structurally rigid (and more conserved) pterin site has been proposed as an alternate strategy to inhibit DHPS in wild-type and sulfa drug resistant strains. Following the work on developing pterin-site inhibitors of the adjacent enzyme 6-hydroxymethyl-7,8 dihydropterin pyrophosphokinase (HPPK), we now present derivatives of 8 mercaptoguanine, a fragment that binds weakly within both enzymes, and quantify sub-MUm binding using surface plasmon resonance (SPR) to Escherichia coli DHPS (EcDHPS). Eleven ligand-bound EcDHPS crystal structures delineate the structure activity relationship observed providing a structural framework for the rational development of novel, substrate-envelope-compliant DHPS inhibitors.

The influence of PBI side chain on the photovoltaic performance of these DPP-based conjugated polymers is systematically investigated. This study suggests that the PBI side chains can not only alter the absorption spectrum and energy level but also enhance the crystallinity of conjugated polymers. As a result, such polymers can act as electron donor, electron acceptor, and single-component active layer in organic solar cells. These findings provide a new guideline for the future molecular design of multifunctional conjugated polymers.

AB - A brand new, soluble quadruple-stranded copolymer is synthesized by using a self template polymer from a new monomer. In addition, another very unique quadruple stranded copolymer having a pi-pi stacking supramolecular polymer main chain is synthesized by selective photocyclic aromatization of the quadruple-stranded copolymer. The two quadruple-stranded copolymers gave self-standing membranes. PMID- 29171697 TI - RuII Photosensitizer-Functionalized Two-Dimensional MoS2 for Light-Driven Hydrogen Evolution. AB - Metallic-phase molybdenum disulfide (1T-MoS2 ) nanosheets have proven to be highly active in the hydrogen evolution reaction (HER). We describe construction of photosensitizer functionalized 1T-MoS2 by covalently tethering the molecular photosensitizer [RuII (bpy)3 ]2+ (bpy=2,2'-bipyridine) on 1T-MoS2 nanosheets. This was achieved by covalently tethering the bpy ligand to 1T-MoS2 nanosheets, and subsequent complexation with [RuII (bpy)2 Cl2 ] to yield [RuII (bpy)3 ]-MoS2 . The obtained [RuII (bpy)3 ]-MoS2 nanosheets were characterized using infra-red, electronic absorption, X-ray photoelectron, and Raman spectroscopies, X-ray powder diffraction and electron microscopy. The fabricated material exhibited a significant improvement of photocurrent and HER performance, demonstrating the potential of such two-dimensional [RuII (bpy)3 ]-MoS2 constructs in photosensitized HER. PMID- 29171698 TI - Construction of Complex Co3 O4 @Co3 V2 O8 Hollow Structures from Metal-Organic Frameworks with Enhanced Lithium Storage Properties. AB - A novel metal-organic-framework-engaged strategy is demonstrated for the preparation of multishelled Co3 O4 @Co3 V2 O8 hybrid nanoboxes. This strategy relies on the unique reaction of zeolitic imidazolate framework-67 with the vanadium source of vanadium oxytriisopropoxide. Benefitting from the synthetic versatility, a series of nanostructures can be realized including triple-shelled and double-shelled Co3 O4 @Co3 V2 O8 nanoboxes and single-shelled Co3 V2 O8 nanoboxes. When evaluated as electrode materials for lithium-ion batteries, these unique hollow structures demonstrate remarkable lithium storage properties. For example, the triple-shelled Co3 O4 @Co3 V2 O8 nanoboxes retain a high capacity of 948 mAh g-1 after 100 cycles at 100 mA g-1 . PMID- 29171699 TI - Higher adaptive functioning and lower rate of psychotic comorbidity in married versus unmarried individuals with 22q11.2 deletion syndrome. AB - 22q11.2 deletion syndrome (22q11.2DS) is a relatively common genetic disorder. Due to improvement in pediatric care, affected individuals live into adulthood, some of whom marry or have committed relationships, and reproduce. The current study aimed to identify the factors that discriminate between married and unmarried adults with 22q11.2DS. In the presents study, 90 adults with 22q11.2DS (48 men/42 women), aged 29.8 +/- 10.3 years, were included in the analysis. Psychiatric comorbidities, IQ score, and adaptive functioning were assessed using gold-standard diagnostic tools. Demographic factors, marital status, and reproductive status were evaluated by self-reports. Of the sample 25 adults (27.7%) were married and 14 (56%) of those had children. Married, as compared to unmarried individuals, were older, had less psychotic comorbidities, showed higher adaptive functioning in all domains of the Vineland Adaptive Behavior Scale, and had higher rates of independent living and sustained employment. Unexpectedly, married individuals showed higher rates of mood disorders and full scale IQ scores did not discriminate between the groups. We propose that multiple factors are associated with marital status among individuals with 22q11.2DS. Identification of key personal, functional, and social characteristics of those who married and reproduced may help counseling health professionals and clinicians in advising affected individuals and their families. PMID- 29171701 TI - Electrochemical Conversion of Phthaldianilides to Phthalazin-1,4-diones by Dehydrogenative N-N Bond Formation. AB - The electrochemical synthesis of 6-membered rings via anodic dianilide N-N coupling is challenging due to concurring benzoxazole co-formation. The rigidity of the a phthalic acid backbone allows a novel access to phthalazin-1,4-diones by N-N bond formation using anodically generated amidyl radicals. Since conventional synthetic routes to phthalazin-1,4-diones require the use of toxic N,N' diarylhydrazines and generate reagent waste, a safer and more sustainable approach is required. Easy accessible starting materials, a broad scope of applicable functional groups, promising yields, and a very simple set-up elevate this sustainable method. PMID- 29171700 TI - Practical strategies for improving outcomes in T2DM: The potential role of pioglitazone and DPP4 inhibitors. AB - T2DM is a complex disease underlined by multiple pathogenic defects responsible for the development and progression of hyperglycaemia. Each of these factors can now be tackled in a more targeted manner thanks to glucose-lowering drugs that have been made available in the past 2 to 3 decades. Recognition of the multiplicity of the mechanisms underlying hyperglycaemia calls for treatments that address more than 1 of these mechanisms, with more emphasis placed on the earlier use of combination therapies. Although chronic hyperglycaemia contributes to and amplifies cardiovascular risk, several trials have failed to show a marked effect from intensive glycaemic control. During the past 10 years, the effect of specific glucose-lowering agents on cardiovascular risk has been explored with dedicated trials. Overall, the cardiovascular safety of the new glucose-lowering agents has been proven with some of the trials summarized in this review, showing significant reduction of cardiovascular risk. Against this background, pioglitazone, in addition to exerting a sustained glucose-lowering effect, also has ancillary metabolic actions of potential interest in addressing the cardiovascular risk of T2DM, such as preservation of beta-cell mass and function. As such, it seems a logical agent to combine with other oral anti-hyperglycaemic agents, including dipeptidyl peptidase-4 inhibitors (DPP4i). DPP4i, which may also have a potential to preserve beta-cell function, is available as a fixed dose combination with pioglitazone, and could, potentially, attenuate some of the side effects of pioglitazone, particularly if a lower dose of the thiazolidinedione is used. This review critically discusses the potential for early combination of pioglitazone and DPP4i. PMID- 29171702 TI - Screening for risk of violence using service users' self-perceptions: A prospective study from an acute mental health unit. AB - Service users' self-perception of risk has rarely been emphasized in violence risk assessments. A recent review pointed to the importance of a multidisciplinary approach, because different perspectives may provide a deeper and improved understanding of risk assessment. The aim of this study was to investigate service users' perceptions of their own risk of committing violence, using a self-report risk scale, to determine the feasibility and efficacy of this potential violence risk marker during acute mental health hospitalization. All service users admitted to a psychiatric emergency hospital in Norway during one calendar year were included (N = 512). Nearly 80% self-reported no risk or low risk; only seven (1.4%) reported moderate risk or high risk. Service users who reported moderate risk, high risk, don't know, or won't answer were more likely to be violent (OR = 4.65, 95% CI = 2.79-7.74) compared with those who reported no risk or low risk. There was a significant gender interaction with higher OR for women on both univariate and multivariate analyses. Although the OR was higher for women, women's violence rate (11.0%) was almost half that of men (21.8%). For women, sensitivity and specificity were 0.55 and 0.88, respectively; corresponding values for men were 0.40 and 0.80. Inclusion of self-perception of violence risk is the first step towards service users' collaborative involvement in violence prediction; these results indicate that self-perception can contribute to violence risk assessments in acute mental health settings. Findings also indicate that there are gender differences in these assessments. PMID- 29171703 TI - Homo- and Copolycyclotrimerization of Aromatic Internal Diynes Catalyzed with Co2 (CO)8 : A Facile Route to Microporous Photoluminescent Polyphenylenes with Hyperbranched or Crosslinked Architecture. AB - This study reports the first Co2 (CO)8 -catalyzed [2+2+2] polycyclotrimerization by the transformation of internal ethynyl groups of aromatic diyne monomers. The reaction yields polycyclotrimers of polyphenylene-type with either hyperbranched or partly crosslinked architecture. The homopolycyclotrimerization of the monomers with two ethynyl groups per one molecule, namely 1,4 bis(phenylethynyl)benzene, 4,4'-bis(phenylethynyl)biphenyl, and 4 (phenylethynyl)phenylacetylene, gives partly crosslinked, insoluble polyphenylenes. The soluble, hyperbranched polyphenylenes are generated via copolycyclotrimerization of 1,4-bis(phenylethynyl)benzene with 1,2 diphenylacetylene (average number of ethynyl groups per monomer molecule < 2). This one-step polycyclotrimerization path to hyperbranched or partly crosslinked polyphenylenes is an alternative to the synthesis of these polymers by Diels Alder transformation of substituted cyclopentadienones. All polyphenylenes prepared exhibit photoluminescence with emission maxima ranging from 381 to 495 nm. Polyphenylenes with a less compact packing of segments are microporous (specific surface area up to 159 m2 g-1 ), which is particularly important in the case of soluble polyphenylenes because they can be potentially used to prepare microporous layers. PMID- 29171704 TI - A qualitative investigation of physical activity compensation among older adults. AB - OBJECTIVES: This study explored the mechanisms of physical activity (PA) compensation among older adults who recently reduced their non-exercise physical activity (NEPA) in response to a structured PA intervention. DESIGN: A post trial, retrospective qualitative process evaluation using interviews was employed. METHODS: Levels of PA compensation were determined by comparing NEPA prior to and during the final week of a 4-week structured PA intervention. Those who reduced their NEPA by 10% or greater were considered as compensators. Interviews were conducted with older adult compensators (mean age = 58.56 +/- 3.88 years; n = 9), employing thematic analysis to identify potential mechanisms of PA compensation. RESULTS: The findings suggest that the majority of participants were unaware that they had compensated in their PA, suggesting that this may be a non-volitional process. Most participants perceived PA compensation to hold negative implications for health and well-being. Physiological processes of fatigue and delayed onset of muscle soreness were cited as the principal cause of PA compensation, whereas psychological processes including a drive to be inactive, fear of overexertion, deficient motivation, and perceived time constraints were cited to a lesser extent. CONCLUSION: A range of physiological and psychological compensatory barriers were identified. Implications of and methods to overcome these compensatory barriers are discussed. Statement of contribution What is already known on this subject? Physical activity compensation holds negative implications for physical activity promotion and health. Older adults are an age group more likely to compensate in their physical activity levels. What does this study add? Physical activity compensation may be a result of a range of physiological and psychological processes including fatigue and delayed onset of muscle soreness, compensatory health beliefs, fear of overexertion, deficient motivation, and perceived time constraints. Most older adult compensators may be unaware they are compensating and, however, agree that physical activity compensation has negative implications for health and well being. PMID- 29171705 TI - Broadening the Photoresponse to Near-Infrared Region by Cooperating Fullerene and Nonfullerene Acceptors for High Performance Ternary Polymer Solar Cells. AB - Ternary polymer solar cells (PSCs) based on multiple materials with level matching and complementary absorptions are regarded as an efficient way to overcome the light-harvesting restriction to surpass high-performance binary PSCs. This study introduces the third component, nonfullerene acceptor IEICO, into binary PSC-based PBDTBDD:PC71 BM to fabricate ternary PSC with one donor and two acceptors. By carefully tuning the third component ratio and cathode engineering, the resulting ternary PSC shows a power conversion efficiency of 10.51%, greatly improved in comparison with binary PSCs-based PBDTBDD:PC71 BM (7.86%) and PBDTBDD:IEICO (5.19%). In addition to extended light absorption, the third component IEICO could accelerate charge-carrier transfer, decrease charge recombination, and increase electron collection, resulting from cascade energy levels, and ameliorate the device morphology to increase the contact area of the active layer and cathode buffer layer. This work demonstrates that ternary PSC incorporated with IEICO is a promising structure for producing high performance PSCs. PMID- 29171706 TI - Controllable Surface Reorganization Engineering on Cobalt Phosphide Nanowire Arrays for Efficient Alkaline Hydrogen Evolution Reaction. AB - Developing highly efficient hydrogen evolution reaction (HER) catalysts in alkaline media is considered significant and valuable for water splitting. Herein, it is demonstrated that surface reorganization engineering by oxygen plasma engraving on electocatalysts successfully realizes a dramatically enhanced alkaline HER activity. Taking CoP nanowire arrays grown on carbon cloth (denoted as CoP NWs/CC) as an example, the oxygen plasma engraving can trigger moderate CoOx species formation on the surface of the CoP NWs/CC, which is visually verified by the X-ray absorption fine structure, high-resolution transmission electron microscopy, and energy-dispersive spectrometer (EDS) mapping. Benefiting from the moderate CoOx species formed on the surface, which can promote the water dissociation in alkaline HER, the surface reorganization of the CoP NWs/CC realizes almost fourfold enhanced alkaline HER activity and a 180 mV decreased overpotential at 100 mA cm-2 , compared with the pristine ones. More interestingly, this surface reorganization strategy by oxygen plasma engraving can also be effective to other electrocatalysts such as free-standing CoP, Co4 N, O-CoSe2 , and C-CoSe2 nanowires, which verifies the universality of the strategy. This work thus opens up new avenues for designing alkaline HER electrocatalysts based on oxygen plasma engraving. PMID- 29171707 TI - Basic Remarks on Acidity.

For this purpose, a brief overview of the concepts acidity, acid strengths, and pH value is given, including problems, proposed solutions, and the use of the pHabs /pHabsH2O scale as a unifying concept. Thereafter, some examples of the accessibility and application of unified pHabs values are given. The Review is rounded off with the analogy of acid-base chemistry to redox chemistry with the introduction of the unified redox scale peabs . The combination of pHabs and peabs values in the protoelectric potential map (PPM), as elaborated in ongoing studies on the thermochemistry of single ions, provides a means to classify and to compare all possible acid-base/redox reactions in a medium-independent and, thus, unified fashion.

PMID- 29171709 TI - The influence of inflammation and hematocrit on clot strength in canine thromboelastographic hypercoagulability. AB - OBJECTIVE: To investigate parameters causing canine thromboelastographic hypercoagulability and to investigate whether thromboelastography (TEG) with Cytochalasin D (Cyt D) added is related to parameters of platelet activity. DESIGN: Prospective observational study on hemostatic and inflammatory parameters. Data were collected between November 2012 and July 2013. SETTING: University teaching hospital. ANIMALS: Twenty-eight dogs suffering from diseases predisposing to thrombosis and 19 clinically healthy dogs. Diseased dogs were enrolled if they fulfilled inclusion criteria regarding age, size, informed client consent, and obtained a diagnosis of a disease that has been associated with thrombosis or hypercoagulability. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Parameters of coagulation and anticoagulation, fibrinolysis, and antifibrinolysis, platelet activity, inflammation, platelet count, and hematocrit were measured using CBC, TEG, platelet aggregation on multiplate, platelet activity on flow cytometry, and hemostatic and inflammatory markers on plasma and serum analyses. ANOVA and multilinear regression analyses indicated that especially hematocrit and the inflammatory parameters C-reactive protein and interleukin-8 showed best association with overall clot strength in diseased dogs with hypercoagulable TEG tracings. Ratios presumed to reflect platelet contribution to the TEG tracing obtained in TEG analyses with Cyt D were related especially with hematocrit and P-selectin expression of platelets measured after gamma-Thrombin activation on flow cytometry. CONCLUSION: Overall clot strength in TEG analyses of the hypercoagulable dogs included in the present study appears to be primarily associated with inflammation as well as hematocrit. Furthermore, the ratio between standard TEG analyses and TEG analyses with Cyt D may reflect some degree of platelet activity. PMID- 29171710 TI - Asymmetrically Encapsulated Vertical ITO/MoS2 /Cu2 O Photodetector with Ultrahigh Sensitivity. AB - Strong light absorption, coupled with moderate carrier transport properties, makes 2D layered transition metal dichalcogenide semiconductors promising candidates for low intensity photodetection applications. However, the performance of these devices is severely bottlenecked by slow response with persistent photocurrent due to long lived charge trapping, and nonreliable characteristics due to undesirable ambience and substrate effects. Here ultrahigh specific detectivity (D*) of 3.2 * 1014 Jones and responsivity (R) of 5.77 * 104 A W-1 are demonstrated at an optical power density (Pop ) of 0.26 W m-2 and external bias (Vext ) of -0.5 V in an indium tin oxide/MoS2 /copper oxide/Au vertical multi-heterojunction photodetector exhibiting small carrier transit time. The active MoS2 layer being encapsulated by carrier collection layers allows us to achieve repeatable characteristics over large number of cycles with negligible trap assisted persistent photocurrent. A large D* > 1014 Jones at zero external bias is also achieved due to the built-in field of the asymmetric photodetector. Benchmarking the performance against existing reports in literature shows a viable pathway for achieving reliable and highly sensitive photodetectors for ultralow intensity photodetection applications. PMID- 29171713 TI - Black Phosphorus Quantum Dots with Renal Clearance Property for Efficient Photodynamic Therapy. AB - Black phosphorus (BP) nanomaterials have emerged as rapidly rising stars in the field of nanomedicine. In this work, BP quantum dots (BPQDs) are synthesized and their potential as photosensitizers is investigated for the first time. The BPQDs present good stability in physiological medium and no appreciable cytotoxicity. More importantly, the BPQDs can be rapidly eliminated from the body in their intact form via renal clearance due to their ultrasmall hydrodynamic diameter (5.4 nm). Both in vitro and in vivo studies indicate that the BPQDs have excellent photodynamic effect under light irradiation that can effectively generate reactive oxygen species to kill cancer cells. The BPQDs thus can serve as biocompatible and powerful photosensitizers for efficient photodynamic therapy. PMID- 29171712 TI - Perspectives in allergen immunotherapy: 2017 and beyond. AB - The Future of the Allergists and Specific Immunotherapy (FASIT) workshop provides a regular platform for global experts from academia, allergy clinics, regulatory authorities and industry to review developments in the field of allergen immunotherapy (AIT). The most recent meeting, held in February 2017, had two main themes: advances in AIT and hot topics in AIT from the regulatory point of view. The first theme covered opportunities for personalized AIT, advances in adjuvants and delivery systems, and the development of new molecules and future vaccines for AIT. Key topics in the second part of the meeting were the effects of the enactment of European Directive 2001/83 on the availability of allergens for therapy and diagnosis across the EU, the challenges of conducting Phase 3 studies in the field, the future role of allergen exposure chambers in AIT studies and specific considerations in performing AIT studies in the paediatric population. Finally, the group highlighted the forthcoming EAACI guidelines and their particular importance for the standardization of practice in the treatment of allergies. This review presents a comprehensive insight into those panel discussions and highlights unmet needs and also possible solutions to them for the future. PMID- 29171714 TI - Biomimetic Materials and Fabrication Approaches for Bone Tissue Engineering. AB - Various strategies have been explored to overcome critically sized bone defects via bone tissue engineering approaches that incorporate biomimetic scaffolds. Biomimetic scaffolds may provide a novel platform for phenotypically stable tissue formation and stem cell differentiation. In recent years, osteoinductive and inorganic biomimetic scaffold materials have been optimized to offer an osteo friendly microenvironment for the osteogenic commitment of stem cells. Furthermore, scaffold structures with a microarchitecture design similar to native bone tissue are necessary for successful bone tissue regeneration. For this reason, various methods for fabricating 3D porous structures have been developed. Innovative techniques, such as 3D printing methods, are currently being utilized for optimal host stem cell infiltration, vascularization, nutrient transfer, and stem cell differentiation. In this progress report, biomimetic materials and fabrication approaches that are currently being utilized for biomimetic scaffold design are reviewed. PMID- 29171715 TI - Restenosis patterns after bioresorbable vascular scaffold implantation: Angiographic substudy of the GHOST-EU registry. AB - OBJECTIVES: To evaluate pattern of in-BVS-restenosis after bioresorbable vascular scaffold (BVS) implantation. BACKGROUND: In-stent restenosis morphology impacts target lesion revascularization (TLR) rates and clinical outcomes. Although several trials report on outcomes after BVS implantation, information about in BVS restenosis pattern is still lacking. METHODS: Between November 2011 and January 2014, in 7 of 10 European centers participating in the GHOST-EU registry, 668 patients underwent BVS implantation. Of them 164 patients (200 lesions) underwent an additional angiogram 3 to 12 months after index PCI. RESULTS: Binary in-BVS restenosis (IBR) (in-segment diameter stenosis >=50%) was observed in 12.7% (21 of 164) of patients (30 lesions), with a TLR rate of 16.5%. The IBR morphology was classified as focal margin in 50.0%, focal body in 26.7%, multifocal in 10.0%, and diffuse in 13.3% of these cases. Treatment of small vessels (OR 5.49, 95% CI 1.6-18.8, P < 0.01) was identified as independent predictor of IBR. Performing predilatation (OR 0.13, 95% CI 0.02-1.04, P = 0.06), high-pressure postdilatation (OR 3.16, 95% CI 0.90-11.18, P = 0.07) as well as treatment of acute coronary syndrome (OR 0.18, 95% CI 0.03-1.12, P = 0.07) seem to strongly influence this risk. CONCLUSIONS: The IBR morphology is mostly focal involving particularly the BVS margins suggesting association with procedural aspects in this early experience with BVS. Treatment of small vessels is the strongest predictor of higher IBR risk. PMID- 29171716 TI - Architecting Graphene Oxide Rolled-Up Micromotors: A Simple Paper-Based Manufacturing Technology. AB - A graphene oxide rolled-up tube production process is reported using wax-printed membranes for the fabrication of on-demand engineered micromotors at different levels of oxidation, thickness, and lateral dimensions. The resultant graphene oxide rolled-up tubes can show magnetic and catalytic movement within the addition of magnetic nanoparticles or sputtered platinum in the surface of graphene-oxide-modified wax-printed membranes prior to the scrolling process. As a proof of concept, the as-prepared catalytic graphene oxide rolled-up micromotors are successfully exploited for oil removal from water. This micromotor production technology relies on an easy, operator-friendly, fast, and cost-efficient wax-printed paper-based method and may offer a myriad of hybrid devices and applications. PMID- 29171717 TI - Sex-related relationships between uric acid and target organ damage in hypertension. AB - Heterogeneous results have been obtained in the relationship between serum uric acid (SUA) and target organ damage (TOD) in patients with hypertension. Clinic blood pressure, SUA, and cardiac, arterial (carotid and aortic), and renal TOD were assessed in 762 consecutive patients with hypertension. Hyperuricemia was defined as an SUA >7.0 in men and >6.0 mg/dL in women. Men with hyperuricemia compared with those with normal SUA showed lower estimated glomerular filtration rates and E/A ratios and a higher prevalence of carotid plaques. Women with hyperuricemia showed lower estimated glomerular filtration rates and E/A ratios and a higher intima-media thickness. Except for pulse wave velocity, all TODs significantly correlated with SUA. However, at multivariate analysis, only estimated glomerular filtration rate was significantly determined by SUA. Our data provide evidence on the role of SUA in the development of TOD only in the case of renal alteration. It is likely that SUA may indirectly act on the other TODs through the increase in blood pressure and the decrease in glomerular filtration rate. PMID- 29171718 TI - Revealing the Fate of Transplanted Stem Cells In Vivo with a Novel Optical Imaging Strategy. AB - Stem-cell-based regenerative medicine holds great promise in clinical practices. However, the fate of stem cells after transplantation, including the distribution, viability, and the cell clearance, is not fully understood, which is critical to understand the process and the underlying mechanism of regeneration for better therapeutic effects. Herein, we develop a dual-labeling strategy to in situ visualize the fate of transplanted stem cells in vivo by combining the exogenous near-infrared fluorescence imaging in the second window (NIR-II) and endogenous red bioluminescence imaging (BLI). The NIR-II fluorescence of Ag2 S quantum dots is employed to dynamically monitor the trafficking and distribution of all transplanted stem cells in vivo due to its deep tissue penetration and high spatiotemporal resolution, while BLI of red emitting firefly luciferase (RfLuc) identifies the living stem cells after transplantation in vivo because only the living stem cells express RfLuc. This facile strategy allows for in situ visualization of the dynamic trafficking of stem cells in vivo and the quantitative evaluation of cell translocation and viability with high temporal and spatial resolution, and thus reports the fate of transplanted stem cells and how the living stem cells help, regeneration, for an instance, of a mouse with acute liver failure. PMID- 29171719 TI - Developing an adherence in hypertension questionnaire short version: MUAH-16. AB - The Maastricht Utrecht Adherence in Hypertension (MUAH) questionnaire provides clinicians with information about the causes of a patient's poor adherence to antihypertensive drugs. In this study, the authors aimed to develop and validate a short version of the MUAH questionnaire. After an exploratory factor analysis, the number of MUAH items was reduced. The original MUAH questionnaire (model 1) was compared with the 16-item MUAH short version (model 2). Next, this short version of MUAH (MUAH-16) with all factors correlated (model 2a) was compared with the short version of MUAH with four subscales that contribute to a global factor of adherence (model 2b). Model 1 had a poor fit to the data (chi2 269 = 663.41, P < .001, comparative fit index = 0.695, root mean square error of approximation = 0.06), and model 2 had a very good fit to the data (chi2 100 = 171.07, P < .001, comparative fit index = 0.92, root mean square error of approximation = 0.04). When comparing model 2a with model 2b, the chi-square difference of the model (Deltachi2 2 = 4.06; P = .067) revealed that the fits of both models were not significantly different. These findings suggest that MUAH-16 better represents a patient's adherence to antihypertensive medication than the original MUAH questionnaire. PMID- 29171720 TI - Building resilience in regional youth: Impacts of a universal mental health promotion programme. AB - Mental health is a leading health issue facing young people today, particularly those living in rural and regional areas. Although public policy supports schools based health promotion, there is limited evidence of the efficacy of such programmes and the elements that enhance successful implementation in rural and regional areas. A study was designed to evaluate a mental health promotion programme, delivered collaboratively by nurses, guidance officers, and teachers, to 850 young people from 23 rural and regional high schools in Queensland, Australia. The study aims were to determine what effect the intervention had on young peoples' resilience, coping, and self-efficacy, and to understand the implications of delivering the programme in the regional Queensland school setting. Students completed self-report measures of self-efficacy, resilience, and coping strategies pre- and postprogramme, as well as at 8-week follow-up. We found that after programme completion there was a significant increase in self efficacy and in the number of positive coping strategies used by the participating young people. Qualitative data indicated that participants benefited from the collaboration between health and education sectors; that is, nurses, guidance officers, and teachers delivered the programme together in ways that were perceived to be respectful of young people and effectively discussion based, and engaging. PMID- 29171721 TI - Heparan sulfate inhibits inflammation and improves wound healing by downregulating the NLR family pyrin domain containing 3 (NLRP3) inflammasome in diabetic rats. AB - BACKGROUND: Heparan sulfate (HS) attenuates the inflammatory response and improves diabetic wound healing in rats. However, the specific mechanisms by which HS suppresses inflammation are not clear. Given that NLR family pyrin domain containing 3 (NLRP3) is a major receptor involved in innate immune regulation, the aim of the present study was to elucidate the effects of HS on NLRP3 and proinflammatory cytokines in diabetic wounds. METHODS: Full-thickness wounds were created on the back of diabetic rats. The experimental group received HS treatment (1 mg/kg, i.m., on Days 0 and 7), whereas the control group received vehicle (0.1% dimethylsulfoxide in 0.9% NaCl). Expression of NLRP3 and its downstream effector molecules, namely cleaved interleukin (IL)-1beta, IL-18, tumor necrosis factor (TNF)-alpha, apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), proteinase inhibitor 9, and caspase-12, in the wound tissues was examined. RESULTS: Treatment with HS accelerated wound healing in diabetic rats. Rats treated with HS exhibited decreased activation of cleaved IL-1beta, IL-18, and TNF-alpha, as well as decreased expression of NLRP3 and ASC. In addition, HS increased levels of proteinase inhibitor 9 and caspase-12. CONCLUSIONS: Heparan sulfate inhibits inflammation and improves wound healing by downregulating the NLRP3 inflammasome and cleaved IL-1beta during the wound healing process in diabetic rats. PMID- 29171722 TI - Magnetically Responsive Elastomer-Silicon Hybrid Surfaces for Fluid and Light Manipulation. AB - Stimuli-responsive surfaces with tunable fluidic and optical properties utilizing switchable surface topography are of significant interest for both scientific and engineering research. This work presents a surface involving silicon scales on a magnetically responsive elastomer micropillar array, which enables fluid and light manipulation. To integrate microfabricated silicon scales with ferromagnetic elastomer micropillars, transfer printing-based deterministic assembly is adopted. The functional properties of the surface are completely dictated by the scales with optimized lithographic patterns while the micropillar array is magnetically actuated with large-range, instantaneous, and reversible deformation. Multiple functions, such as tunable wetting, droplet manipulation, tunable optical transmission, and structural coloration, are designed, characterized, and analyzed by incorporating a wide range of scales (e.g., bare silicon, black silicon, photonic crystal scales) in both in-plane and out-of plane configurations.

AB - An electrochemical cell comprising a novel dual-component graphite and Earth crust abundant metal anode, a hydrogen producing cathode and an aqueous sodium chloride electrolyte was constructed and used for carbon dioxide mineralisation. Under an atmosphere of 5 % carbon dioxide in nitrogen, the cell exhibited both capacitive and oxidative electrochemistry at the anode. The graphite acted as a supercapacitive reagent concentrator, pumping carbon dioxide into aqueous solution as hydrogen carbonate. Simultaneous oxidation of the anodic metal generated cations, which reacted with the hydrogen carbonate to give mineralised carbon dioxide. Whilst conventional electrochemical carbon dioxide reduction requires hydrogen, this cell generates hydrogen at the cathode. Carbon capture can be achieved in a highly sustainable manner using scrap metal within the anode, seawater as the electrolyte, an industrially relevant gas stream and a solar panel as an effective zero-carbon energy source.

AB - PURPOSE: To investigate the retinal features and distribution of paravascular abnormalities (PVAs) and their relationship with retinoschisis in eyes with high myopia. METHODS: One hundred and fifty-two eyes of 88 patients with high myopia [refractive error greater than -6 dioptres (D) or axial length (AL) >=26.5 mm] who had undergone comprehensive ophthalmic examinations were evaluated in this cross-sectional study. Multiple optical coherence tomography (OCT) scans were performed to study the microstructural alterations adjacent to the retinal vascular arcades and the entire macular area. The presence and distribution patterns of various PVAs, retinoschisis and the association between these parameters were analysed. RESULTS: Of the 152 highly myopic eyes, PVAs were detected by OCT in 126 eyes (82.9%), including paravascular microfolds in all 126 eyes, paravascular cysts in 109 eyes (71.7%) and paravascular lamellar holes in 44 eyes (28.9%). All three types of PVAs were observed more frequently along the temporal vascular arcades than along the nasal vascular arcades (p < 0.005). Seventy-eight eyes (51.3%) were identified with retinoschisis at retinal vascular arcades, most frequently in the inner plexiform layer (IPL) and along temporal arcades. Eyes with all three types of PVAs (microfolds, cysts and lamellar holes) had the highest incidence of retinoschisis at vascular arcades (p < 0.001). Multivariate analysis indicated that age, the AL, presence of paravascular microfolds and cysts, and simultaneously existence of all three types of PVAs were associated with an increased risk for retinoschisis at vascular arcades. Macular retinoschisis was detected in 25 eyes (19.8%) and presented with splitting of the outer retina in all cases. All seven eyes with entire macular area retinoschisis (S4 grade) were accompanied by retinoschisis at vascular arcades within multiple layers, including outer retinoschisis, IPL schisis and inner limiting membrane (ILM) detachment. CONCLUSION: Our findings indicated that all three types of PVAs and different types of retinoschisis were most frequently observed along the temporal vascular arcades. Eyes with paravascular microfolds and cysts, and those with all three paravascular lesions may in risk of developing retinoschisis at vascular arcades.

AB - PURPOSE: To investigate factors associated with choroidal microcirculation in the peripapillary chorioretinal atrophy (PPA) zone in eyes with normal-tension glaucoma (NTG) and myopic disc. METHODS: In 100 eyes of 100 NTG patients with myopic disc and 20 eyes of 20 age-matched myopic controls, 4.5 * 4.5 mm scans were made of the optic nerve head with optical coherence tomography angiography (OCTA). Peripapillary chorioretinal atrophy (PPA) area and PPA superficial choroidal image intensity (PPA-CI) were calculated with image j software. Clinical characteristics, laser speckle flowgraphy-measured mean blur rate in the temporal tissue area (temporal MT), the central thresholds (the averaged standard automated perimetry-measured visual field thresholds in the four paracentral points) and 3D-OCT-measured ganglion cell complex thickness in the papillomacular bundle (PMB-GCCT) were recorded. RESULTS: The NTG patients had significantly lower intraocular pressure, PMB-GCCT and central threshold values, and a larger PPA area, than the controls. The area under the receiver operating characteristics curve to differentiate NTG with parafoveal scotoma (PFS) from controls was 0.76 for temporal MT, 0.85 for PPA-CI and 0.87 for PMB-GCCT. Univariate and multivariate analyses revealed that PPA-CI was negatively correlated with age, pulse rate, best-corrected visual acuity, axial length and PPA area, and positively correlated with temporal MT, PMB-GCCT and the central thresholds. CONCLUSION: Peripapillary chorioretinal atrophy (PPA)-CI was associated with temporal MT, ageing, bradycardia, axial length elongation and changes in central retinal structure and visual function in patients with NTG and myopic disc. Thus, microcirculation deep within the PPA zone might be a clinically useful biomarker of PFS in NTG.

AB - Obtaining a wavelength division multiplexer (WDM) at the micro/nanometer level is a considerable challenge that holds great potential in optical communication technology owing to the enlarged data-carrying capacity without laying more fibers. Of the progress that has been made in recent years, one of the most promising methods is to fabricate nanoscale pattern on silicon substrate, forcing signals of different wavelength to enter predesigned channels due to the alternant changes in refractive index. However, it is not an easy task to incorporate light sources into these WDM systems, because of the nonradiative characteristics of silicon itself. This study demonstrates a successful integration of laser signal sources and WDM fully with 1D semiconductor structures. Nanowires from II-VI semiconductor serve as both lasing media and low loss waveguides for signal loading and delivering, respectively. On the basis of the distinct size-dependent cut-off effect, finely tuning the diameters of homojunctions would result in a controllable filtering of confined signal that light, beyond cut-off wavelength, cannot transfer within the narrowed segments any longer. These results pave the way for semiconductor photonic components toward integration. PMID- 29171728 TI - Sanger sequencing.

PMID- 29171729 TI - Long-term outcomes in unilateral vocal fold paralysis patients. AB - OBJECTIVES/HYPOTHESIS: At presentation, unilateral vocal fold paralysis (UVFP) patients have different treatment options, including conservative management (CM), injection laryngoplasty (IL) with a temporary agent, or permanent medialization (PM). This study evaluates long-term outcomes for UVFP patients relative to intervention. STUDY DESIGN: Retrospective chart review. METHODS: A retrospective chart review was performed of UVFP patients who presented to the University of California San Francisco Voice and Swallowing Center. Videolaryngostroboscopy examinations were reviewed. Maximum glottic closure was quantified with the normalized glottic gap area (NGGA). Perceptual voice analysis was performed using the Consensus Auditory-Perceptual Evaluation of Voice (CAPE V) at corresponding time points. RESULTS: Fifty-three patients met inclusion criteria. Six underwent CM only, 20 went on to require PM, 19 underwent IL only, and eight underwent IL and subsequent PM. NGGA at presentation was similar among groups; however, the CM group was noted to have more favorable CAPE-V scores for Breathiness (P = .007) and Loudness (P = .018). All groups had similar NGGA and CAPE-V scores at last follow-up. When compared to pooled data for patients who underwent PM, the IL group was noted to have similar NGGA and CAPE-V scores at presentation. Although improvements in both groups were noted following intervention, both groups appeared similar at last follow-up with the exception of Roughness, for which the IL group retained a slightly improved outcome (13.3 vs. 18.3, P = .03). CONCLUSIONS: At presentation, UVFP patients have similar NGGA. This finding suggests that treatment recommendations cannot be made on the size of the glottic gap alone. Furthermore, in many patients, IL results in long term benefit with glottic closure and CAPE-V scores equivalent to that obtained with PM. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:430-436, 2018. PMID- 29171730 TI - The JUPITER registry: One-year outcomes of transapical aortic valve implantation using a second generation transcatheter heart valve for aortic regurgitation. AB - OBJECTIVES: We present 1-year outcomes of the post-market registry of a next generation transcatheter heart valve used for aortic regurgitation (AR). BACKGROUND: Transcatheter aortic valve replacement (TAVR) is routine in high-risk patients with aortic stenosis but is not recommended for AR. The JenaValveTM (JenaValve Technology GmbH, Munich, Germany) overcomes technical challenges in AR patients through a leaflet clipping mechanism. METHODS: The JenaValve EvalUation of Long Term Performance and Safety In PaTients with SEvere Aortic Stenosis oR Aortic Insufficiency (JUPITER) Registry is a European study to evaluate safety and effectiveness of this THV. From 2012-2015, 30 patients with AR were enrolled. RESULTS: Mean age was 74.4 +/- 9.3 years. Procedural success was 96.7% (29/30). One patient was converted to open surgery. No annular rupture or coronary ostia obstruction occurred. Mortality at 30 days was 10.0% (3/30). Combined safety endpoint was met in 13.3% (4/30). Paravalvular regurgitation was not present/trivial in 84.6% (22/26) and mild in 15.4% (4/26). Rate of permanent pacemaker implantation was 3.8% (1/26). One-year Kaplan-Meier survival was 79.9%, one-year combined efficacy was 73.1% (19/30). No further strokes were observed during 1 year of follow-up. CONCLUSIONS: The JenaValve overcomes technical challenges of TAVR in AR through a clipping mechanism. We report satisfactory outcomes of a multicenter registry using the JenaValve for predominant AR, as rate of THV embolization, residual AR and permanent pacemaker implantation was low. One-year results using the JenaValve for AR encourage its use for this indication. PMID- 29171731 TI - Expressions of Mast Cell Tryptase and Brain Natriuretic Peptide in Myocardium of Sudden Death due to Hypersensitivity and Coronary Atherosclerotic Heart Disease. AB - OBJECTIVES: To explore the value of mast cell tryptase and brain natriuretic peptide(BNP) in the differential diagnostic of sudden death due to hypersensitivity and coronary atherosclerotic heart disease. METHODS: Totally 30 myocardial samples were collected from the autopsy cases in the Department of Forensic Pathology, Shanxi Medical University during 2010-2015. All samples were divided into three groups: death of craniocerebral injury group, sudden death of hypersensitivity group and sudden death of coronary atherosclerotic heart disease group, 10 cases in each group. Mast cell tryptase and BNP in myocardium were detected by immunofluorescence staining and Western Blotting. RESULTS: Immunofluorescence staining showed that the positive staining mast cell tryptase appeared in myocardium of sudden death of hypersensitivity group and coronary atherosclerotic heart disease group. Among the three groups, the expression of mast cell tryptase showed significantly differences through pairwise comparison (P<0.05); The expression level of BNP in sudden death of coronary atherosclerotic heart disease group were significantly higher than the sudden death of hypersensitivity group and death of craniocerebral injury group (P<0.05). The difference of the expression level of BNP between the sudden death of hypersensitivity group and the death of craniocerebral injury group had no statistical significance (P>0.05). CONCLUSIONS: The combined detection of the mast cell tryptase and BNP in myocardium is expected to provide help for the forensic differential diagnosis of sudden death due to hypersensitivity and coronary atherosclerotic heart disease. PMID- 29171732 TI - Correlation between RNA Degradation Patterns of Rat's Brain and Early PMI at Different Temperatures. AB - OBJECTIVES: To explore the correlation between early postmortem interval (PMI) and eight RNA markers of rat's brain at different temperatures. METHODS: Total 222 SD rats were randomly divided into control group (PMI=0 h) and four experimental groups. And the rats in the experimental groups were sacrificed by cervical dislocation and respectively kept at 5 C, 15 C, 25 C and 35 C in a controlled environment chamber. The RNA was extracted from brain tissues, which was taken at 9 time points from 1 h to 24 h postmortem. The expression levels of eight markers, beta-actin, GAPDH, RPS29, 18S rRNA, 5S rRNA, U6 snRNA, miRNA-9 and miRNA-125b, were detected using real-time fluorescent quantitative PCR, respectively. Proper internal reference was selected by geNorm software. Regression analysis of normalized RNA markers was performed by SPSS software. Mathematical model for PMI estimation was established using R software. Another 6 SD rats with known PMI were used to verify the mathematical model. RESULTS: 5S rRNA, miR-9 and miR-125b were suitable as internal reference markers for their stable expression. Both beta-actin and GAPDH had well time-dependent degradation patterns and degraded continually with prolongation of PMI in 24 h postmortem. The mathematical model of the variation of DeltaCt values with PMI and temperature was set up by R software and the model could be used for PMI estimation. The average error rates of model validation using beta-actin and GAPDH were 14.1% and 22.2%, respectively. CONCLUSIONS: The expression levels of beta-actin and GAPDH are well correlated with PMI and environmental temperature. The mathematical model established in present study can provide references for estimating early PMI under various temperature conditions. PMID- 29171733 TI - Detection of Metabolism Function of Microbial Community of Corpses by Biolog-Eco Method. AB - OBJECTIVES: To detect the changes of microbial community functional diversity of corpses with different postmortem interval (PMI) and to evaluate forensic application value for estimating PMI. METHODS: The cultivation of microbial community from the anal swabs of a Sus scrofa and a human corpse placed in field environment from 0 to 240 h after death was performed using the Biolog-Eco Microplate and the variations of the absorbance values were also monitored. Combined with the technology of forensic pathology and flies succession, the metabolic characteristics and changes of microbial community on the decomposed corpse under natural environment were also observed. RESULTS: The diversity of microbial metabolism function was found to be negatively correlated with the number of maggots in the corpses. The freezing processing had the greatest impact on average well color development value at 0 h and the impact almost disappeared after 48 h. The diversity of microbial metabolism of the samples became relatively unstable after 192 h. The principal component analysis showed that 31 carbon sources could be consolidated for 5 principal components (accumulative contribution ratio >90%).The carbon source tsquare-analysis showed that N-acetyl D-glucosamine and L-serine were the dominant carbon sources for estimating the PMI (0=240 h) of the Sus scrofa and human corpse. CONCLUSIONS: The Biolog-Eco method can be used to reveal the metabolic differences of the carbon resources utilization of the microbial community on the corpses during 0-240 h after death, which could provide a new basis for estimating the PMI. PMID- 29171734 TI - Research on Auditory Long Latency Response in Normal Hearing Subjects. AB - OBJECTIVES: To explore the characters and the relationship among latency response, amplitude and sound stimulus intensity of auditory long latency response(ALR), and to investigate the significance of ALR applied in auditory threshold prediction. METHODS: Total 46 subjects (92 ears) with normal hearing were tested by ALR. The ALR waves of the subjects were elicited by 5 sound stimulus intensity according to the order of 70, 50, 30, 20 and 10 dB nHL. By making N1 wave and P2 wave, the values of 3 observed indexes (the latencies of N1 wave and P2 wave and N1-P2 amplitude) were obtained, and the variation trend of the observed indexes were statistically analyzed. The differences in the frequency of the indexes were observed. RESULTS: The rate of ALR waves from 46 subjects (92 ears) with normal hearing was 100%. The latencies of N1 wave and P2 wave delayed gradually and N1-P2 amplitude declined with sound stimulus intensity descending. CONCLUSIONS: In suitable conditions, ALR is a stable technology for hearing thresholds prediction. The relation between sound stimulus intensity and latency of N1 wave, latency of P2 wave and N1-P2 amplitude of ALR plays an important part in auditory thresholds assessment.

The specificity, identity, sensitivity, balance of the amplification, anti-interference and accuracy of the system were detected and the gene diversity was investigated in the population of Guangdong. RESULTS: No band was found in nonhuman and female samples that were tested by the established multiplex amplification system. The same genotyping results were obtained from different tissues of the same person. Complete profiles could be obtained from more than 0.1 ng of the standard sample 9948. The loss of alleles was found when the common inhibitors such as hemoglobin and calcium ion were added 120-200 MUmol/L and 1.5 2.0 mmol/L respectively to the system which with a strong anti-interference to the indigo, humic acid and EDTA. The typing of 24 Y-STR system could give the reliable results when 146 unrelated male individuals were detected and compared with the Yfiler system parallelly. The haplotype diversity (HD) of the population in Guangdong reached 0.999 72 that was better than the result retained from Yfiler system, which the HD was 0.998 58. CONCLUSIONS: The fluorescence amplification system with 24 Y-STR loci established in present study has a wildly application prospect and can be used for cases inspection, paternity tests and Y STR database construction.

AB - OBJECTIVES: To investigate the single nucleotide polymorphism (SNP) and haplotypes in differentially methylated region (DMR) upstream of H19 gene in Guangdong Han population. METHODS: The PIA typing and restriction enzyme McrBC and HpaII were used to digest the genomic DNA and obtain the individual uniparental DNA template strand. The data of uniparental SNP alleles, genotypes and haplotypes in DMR upstream of H19 gene were obtained by sequencing. RESULTS: A total of 13 SNPs (rs10840167, rs2525883, rs12417375, rs4930101, rs2525882, rs2735970, rs2735971, rs11042170, rs2735972, rs10732516, rs2071094, rs2107425, and rs4930098) and one mutation locus (g7351c) were found. All loci followed the Hardy-Weinberg equilibrium (P>0.05) by statistical analysis. Except for rs12417375 (DP=0.279) locus, the DP of remaining 12 SNPs were 0.446-0.614, and the g7351c mutation locus (DP=0.013) was the particular loci of the Southern Chinese Han population. Eight haplotypes (designated as haplotype 1-8) were detected, in which 3 haplotypes had not yet been reported and the DP, PIC, PE and H were 0.891, 0.714, 0.524 and 0.758, respectively. CONCLUSIONS: Obtained by PIA typing, the SNP in DMR upstream of H19 gene and its haplotypes genetic marker system have a high determination power and show a good practical value in forensic identification.

PMID- 29171741 TI - Source Identification of Human Biological Materials and Its Prospect in Forensic Science. AB - Source identification of human biological materials in crime scene plays an important role in reconstructing the crime process. Searching specific genetic markers to identify the source of different human biological materials is the emphasis and difficulty of the research work of legal medical experts in recent years. This paper reviews the genetic markers which are used for identifying the source of human biological materials and studied widely, such as DNA methylation, mRNA, microRNA, microflora and protein, etc. By comparing the principles and methods of source identification of human biological materials using different kinds of genetic markers, different source of human biological material owns suitable marker types and can be identified by detecting single genetic marker or combined multiple genetic markers. Though there is no uniform standard and method for identifying the source of human biological materials in forensic laboratories at present, the research and development of a series of mature and reliable methods for distinguishing different human biological materials play the role as forensic evidence which will be the future development direction.

AB - Diphenylphosphinoethane (DPPE)-catalyzed and ZnI2-promoted in situ formation of oxazolidine, alkynyl zinc, and propargylamine intermediates from 1-alkynes, chiral (S)-diphenyl(pyrrolidin-2-yl)methanol, and propiolates gave the corresponding chiral (R)-beta-allenoates in 40-72% yield with up to >99% ee. The intermediate propargylamine was isolated in 50% yield and converted to give the beta-allenoate 10aa in 68% yield and 96% ee upon reaction with ZnI2. The results are discussed considering a mechanism involving oxazolidine and iminium ions formed in situ followed by addition of alkynyl zinc complex to produce the propargylamine that gives the corresponding allenoate via a 1,5-hydrogen shift in the presence of ZnI2.

AB - This comprehensive review surveys the up-to-date development of aggregation induced emission/aggregation-induced emission enhancement (AIE/AIEE) active naphthalimide (NI)-based smart materials with potential for wide and real-world applications and that serves as a highly versatile building block with tunable absorption and emission in the complete visible region. The review article commences with a precise description of the importance of NI moiety and its several restricted area of applications owing to its aggregation caused quenching (ACQ) properties, followed by the discovery and importance of AIE/AIEE-active NIs. The introduction section tracked an overview of the state of the art in NI luminogens in multiple applications. It also includes a few mechanistic studies on the structure-property correlation of NIs and provides more insights into the condensed-state photophysical properties of small aggregation-prone systems. The review aims to ultimately accomplish current and forthcoming views comprising the use of the NIs for the detection of biologically active molecules, such as amino acids and proteins, recognition of toxic analytes, fabrication of light emitting diodes, and their potential in therapeutics and diagnostics. PMID- 29171748 TI - Sensitivities of Simulated Source Contributions and Health Impacts of PM2.5 to Aerosol Models. AB - Chemical transport models are useful tools for evaluating source contributions and health impacts of PM2.5 in the atmosphere. We recently found that concentrations of PM2.5 compounds over Japan were much better reproduced by a volatility basis set model with an enhanced dry deposition velocity of HNO3 and NH3 compared with a two-product yield model. In this study, we evaluated the sensitivities to organic aerosol models of the simulated source contributions to PM2.5 concentrations and of PM2.5-related mortality. Overall, the simulated source contributions to PM2.5 were similar between the two models. However, because of the improvements associated with the volatility basis set model, the contributions of ammonia sources decreased, particularly in winter and spring, and contributions of biogenic and stationary evaporative sources increased in spring and summer. The improved model estimated that emission sources in Japan contributed 35%-48% of the PM2.5-related mortality in Japan. These values were higher than the domestic contributions to average PM2.5 concentrations in Japan (26%-33%) because the domestic contributions were higher in higher population areas. These results indicate that control of both domestic and foreign emissions is necessary to reduce health impacts due to PM2.5 in Japan.

AB - Silver nanoparticles (AgNPs) and their assembled nanostructures such as core/satellite nanoassemblies are quite attractive in plasmonic-based applications. However, one biggest drawback of the AgNPs is the poor chemical stability which also greatly limits their applications. We report fine Au coating on synthesized quasi-spherical silver nanoparticles (AgNSs) with few atomic layers to several nanometers by stoichiometric method. The fine Au coating layer was confirmed by energy-dispersive X-ray spectroscopy elemental mapping and aberration-corrected high-angle annular dark-field scanning transmission electron microscopy. The optimized minimal thickness of Au coating layer on different sized AgNSs (22 nm Ag@0.9 nm Au, 44 nm Ag@1.8 nm Au, 75 nm Ag@2.9 nm Au, and 103 nm Ag@0.9 nm Au) was determined by extreme chemical stability tests using H2O2, NaSH, and H2S gas. The thin Au coating layer on AgNSs did not affect their plasmonic-based applications. The core/satellite assemblies based on Ag@Au NPs showed the comparable SERS intensity and uniformity three times higher than that of noncoated Ag core/satellites. The Ag@Au core/satellites also showed high stability in intracellular SERS imaging for at least two days, while the SERS of the noncoated Ag core/satellites decayed significantly. These spherical Ag@Au NPs can be widely used and have great advantages in plasmon-based applications, intracellular SERS probes, and other biological and analytical studies.

AB - Development of intrinsically safe and long lifespan sodium-ion batteries (SIBs) is urgently needed for large-scale energy storage applications. However, most of the currently developed SIBs suffer from insufficient cycle life and potential unsafety. Herein, we construct an all-phosphate sodium-ion battery (AP-SIB) using a Na3V2(PO4)3 cathode, NaTi2(PO4)3 anode, and nonflammable trimethyl phosphate (TMP) electrolyte. The AP-SIB exhibits not only high safety, high rate performance, and ultralong cycle life but also zero-strain characteristics due to the inverse volume change of the phosphate cathode and anode during charge and discharge cycles, offering a safer and cycle-stable Na-ion technology for electric storage applications. PMID- 29171751 TI - From Cellulose Nanospheres, Nanorods to Nanofibers: Various Aspect Ratio Induced Nucleation/Reinforcing Effects on Polylactic Acid for Robust-Barrier Food Packaging. AB - The traditional approach toward improving the crystallization rate as well as the mechanical and barrier properties of poly(lactic acid) (PLA) is the incorporation of nanocelluloses (NCs). Unfortunately, little study has been focused on the influence of the differences in NC morphology and dimensions on the PLA property enhancement. Here, by HCOOH/HCl hydrolysis of lyocell fibers, microcrystalline cellulose (MCC), and ginger fibers, we unveil the preparation of cellulose nanospheres (CNS), rod-like cellulose nanocrystals (CNC), and cellulose nanofibers (CNF) with different aspect ratios, respectively. All the NC surfaces were chemically modified by Fischer esterification with hydrophobic formate groups to improve the NC dispersion in the PLA matrix. This study systematically compared CNS, CNC, and CNF as reinforcing agents to induce different kinds of heterogeneous nucleation and reinforce the effects on the properties of PLA. The incorporation of three NCs can greatly improve the PLA crystallization ability, thermal stability, and mechanical strength of nanocomposites. At the same NC loading level, the PLA/CNS showed the highest crystallinity (19.8 +/- 0.4%) with a smaller spherulite size (33 +/- 1.5 MUm), indicating that CNS, with its high specific surface area, can induce a stronger heterogeneous nucleation effect on the PLA crystallization than CNC or CNF. Instead, compared to PLA, the PLA/CNF nanocomposites gave the largest Young's modulus increase of 350 %, due to the larger aspect ratio/rigidity of CNF and their interlocking or percolation network caused by filler-matrix interfacial bonds. Furthermore, taking these factors of hydrogen bonding interaction, increased crystallinity, and interfacial tortuosity into account, the PLA/CNC nanocomposite films showed the best barrier property against water vapor and lowest migration levels in two liquid food simulates (well below 60 mg kg-1 for required overall migration in packaging) than CNS- and CNF-based films. This comparative study was very beneficial for selecting reasonable nanocelluloses as nucleation/reinforcing agents in robust-barrier packaging biomaterials with outstanding mechanical and thermal performance. PMID- 29171752 TI - Solution-Processed Flexible Organic Ferroelectric Phototransistor. AB - In this article, we demonstrate ferroelectric insulator, P(VDF-TrFE), can be integrated with red light sensitive polymeric semiconductor, P(DPP-TzBT), toward ferroelectric organic phototransistors (OPTs). This ferroelectricity-modulated phototransistor possesses different nonvolatile and tunable dark current states due to P(VDF-TrFE)'s remnant polarization. As a result, the OPT is endowed with a tunable dark current level ranging from 1 nA to 100 nA. Once the OPT is programmed or electrically polarized, its photo-to-dark (signal-to-noise) ratio can be "flexible" during photodetection process, without gate bias application. This kind of organic ferroelectric phototransistor has great potential in detecting wide ranges of light signals with good linearity. Moreover, its tuning mechanism discussed in this work can be helpful to understand the operation mechanism of organic phototransistor (OPT). It can be promising for novel photodetection application in plastic electronic devices.

AB - Herein, we report an alternative synthetic approach for selected 2,6,9 trisubstituted purine CDK inhibitor conjugates with folic acid as a drug-delivery system targeting folate receptors. In contrast to the previously reported approaches, the desired conjugates were constructed stepwise using solid-phase synthesis starting from immobilized primary amines. The ability of the prepared conjugates to release the free drug was verified using dithiothreitol (DTT) and glutathione (GSH) as liberating agents. Finally, binding to the folate receptor (FOLR1) overexpressed in a cancer cell line was measured by flow cytometry using a fluorescent imaging probe.

AB - Using the synthetic strategy of palladium-catalyzed dual activation of both C-I and vicinal C-H bonds of diaryliodonium salts, we report an approach for direct diarylations of 2-bromobiphenyls or bromobenzenes. As a result, a wide range of triphenylenes with various substituents have been synthesized in good yields. These triphenylenes are expected to be employed in the "bottom-up" synthesis of functional aromatic molecules in material science.

AB - New Si-phenyl-substituted silacyclohexanes and 3-silatetrahydropyrans have been synthesized and studied with respect to the conformational equilibria of the heterosix-membered ring by low temperature 13C NMR spectroscopy and quantum chemical calculations. For 1-methoxy-1-phenylsilacyclohexane 1 and 3-phenyl-3 silatetrahydropyran 4 the conformational equilibria could be frozen and assigned. The Phax ? Pheq equilibrium constants at 103 K are 2.21 for 1 and 4.59 for 4. In complete agreement with former studies of similar silicon compounds, molecules 1 and 4 prefer to adopt the Pheq conformation. The conformational equilibria of 1 hydroxy-1-phenylsilacyclohexane 2 and 3-hydroxy-3-phenyl-3-silatetrahydropyran 3 could not be frozen at 100 K and proved to be heavily one-sided (if not anancomeric). Obviously, there is a general trend of predominance of Phax conformer in the gas phase and of Pheq in solution. For the isolated molecules of silanols 2 and 3, calculations allowed to explain the axial predominance of the phenyl group by a larger polarization of the Si-Ph than of the Si-O bond in the Phax conformer and additional destabilization of 3-Pheq conformer by repulsion of unidirectional dipoles of the endocyclic oxygen lone pair and of the highly polar axial Si-O bond.

PMID- 29171757 TI - Impedimetric Sensor of ss-HSDNA/Reduced Graphene Oxide Aerogel Electrode toward Aflatoxin B1 Detection: Effects of Redox Mediator Charges and Hydrodynamic Diffusion. AB - Here, an impedimetric biosensor for determination and quantification of an aflatoxin B1 (AFB1) level using a reduced graphene oxide aerogel labeled with a single strand DNA (ss-HSDNA/rGOae) modified on a rotating disk electrode (RDE) is presented. Owing to the large biomolecule biding on the electrode, an electron transfer is interrupted and not easily accessible to a target molecule. To address this issue, we aim to study two effects; one considers electro-redox mediators and the other considers the hydrodynamic effect. By observing a cyclic voltammetric response from the ss-HSDNA/rGOae electrode in three different charges of the redox mediators (i.e., neutral FcCH2OH, cationic Ru(NH3)63+, and anionic Fe(CN)64-) in a phosphate buffer solution (PBS) containing AFB1, the magnitude of anodic current at 50 mV s-1 is 825, 615, and 550 mA cm-1, respectively, which is significant dominated by the charge of the redox probe. The effect of hydrodynamic diffusion of the ss-HSDNA/rGOae rotating disk electrode (RDE) toward AFB1 detection using FcCH2OH as the redox mediator was recorded by applying a range of rotating speed from 500 to 4000 rpm. Increasing rotating speed reduces the charge transfer resistance resulting in the lower detectable level for AFB1 quantification. In the case of 4000 rpm, the AFB1 can be detected with a limit of detection of 0.04 ng/mL and a linear range of 1 * 10 10 to 7 * 10-8g/mL. PMID- 29171758 TI - Toward best practices in data processing and analysis for intact biotherapeutics by MS in quantitative bioanalysis. AB - AIM: Typically, quantitation of biotherapeutics from biological matrices by LC-MS is based on a surrogate peptide approach to determine molecule concentration. Recent efforts have focused on quantitation of the intact protein molecules or larger mass subunits of monoclonal antibodies. To date, there has been limited guidance for large or intact protein mass quantitation for quantitative bioanalysis. METHODOLOGY: Intact- and subunit-level analyses of biotherapeutics from biological matrices are performed at 12-25 kDa mass range with quantitation data presented. RESULTS: Linearity, bias and other metrics are presented along with recommendations made on the viability of existing quantitation approaches. CONCLUSION: This communication is intended to start a discussion around intact protein data analysis and processing, recognizing that other published contributions will be required. PMID- 29171759 TI - Microdosing, isotopic labeling, radiotracers and metabolomics: relevance in drug discovery, development and safety. AB - This review discusses the use of stable (13C, 2D) or radioactive isotopes (14C, 11C, 18F, 131I, 64Cu, 68Ga) incorporated into the molecular structure of new drug entities for the purpose of pharmacokinetic or -dynamic studies. Metabolite in safety testing requires the administration of pharmacologically active doses. In such studies, radiotracers find application mainly in preclinical animal investigations, whereby LC-MS/MS is used to identify metabolite structure and drug-related effects. In contrast, first-in-human metabolite studies have to be carried out at nonpharmacological doses not exceeding 100 MUg (microdose), which is generally too low for metabolite detection by LC-MS/MS. This short-coming can be overcome by specific radio- or isotopic labeling of the drug of interest and measurements using accelerator mass spectroscopy, single-photon emission computed tomography and positron emission tomography. Such combined radioisotope-based approaches permit Phase 0, first-in-human metabolite study.

PMID- 29171761 TI - New agents for the management of resistant metastatic breast cancer. AB - INTRODUCTION: Metastatic breast cancer (MBC) is an incurable disease and treatment is directed towards symptom palliation and survival prolongation. Treatment selection in patients is based on tumor biology, age, comorbidities, performance status, tumor burden, and prior treatment history. Areas covered: This present review summarizes the recent treatment strategies in the management of MBC, highlighting regimens after first-line therapy. Topics discussed include new strategies for endocrine therapy, anti-HER2 therapy, and promising strategies for the management of triple negative breast cancer. Expert opinion: MBC is a heterogeneous entity and despite recent advances, there is significant room for improvement of treatment beyond first-line therapies. Combination regimens that can maximize clinical efficacy while minimizing toxicities are required. Current investigation approaches in advanced stages of clinical development include immunoconjugates, immune checkpoint blockade, novel cyclin-dependent-kinase inhibitors, and PARP inhibitors for MBC associated with germline BRCA mutations. We recommend that every patient with MBC should be evaluated for clinical trial options.

PMID- 29171762 TI - PLK4: a link between centriole biogenesis and cancer. AB - INTRODUCTION: Polo like kinase (PLK) is known to play a pivotal role in various cell cycle processes to perpetuate proper division and growth of the cells. Polo like kinase-4 (PLK4) is one such kinase that appears in low abundance and plays a well-characterized role in centriole duplication. PLK4 deregulation (i.e. both overexpression and depletion of PLK4), leads to altered mitotic fidelity and thereby triggers tumorigenesis. Hence, over the last few years PLK4 has emerged as a potential therapeutic target for the treatment of various advanced cancers. Areas covered: In this review, we discuss the basic structure, expression, localization and functions of PLK4 along with its regulation by various proteins. We also discuss the role of altered PLK4 activity in the onset of cancer and the current pre-clinical and clinical inhibitors to regulate PLK4. Expert opinion: PLK4 mediated centriole duplication has a crucial role in maintaining mitotic correctness in normal cells, while its deregulation has a greater impact on genesis of cancer. Henceforth, a deep knowledge of the PLK4 levels, its role and interactions with various proteins in cancer is required to design effective inhibitors for clinical use. PMID- 29171764 TI - Loneliness and social isolation among young and late middle-age adults: Associations with personal networks and social participation. AB - OBJECTIVE: Associations between social networks and loneliness or social isolation are well established among older adults. Yet, limited research examines personal networks and participation on perceived loneliness and social isolation as distinct experiences among younger adults. Accordingly, we explore relationships among objective and subjective measures of personal networks with loneliness and isolation, comparing a younger and older cohort. METHODS: The UC Berkeley Social Networks Study offers unique cohort data on young (21-30 years old, n = 472) and late middle-age adults' (50-70 years old, n = 637) personal network characteristics, social participation, network satisfaction, relationship status, and days lonely and isolated via online survey or in-person interview. Negative binomial regression models were used to examine associations between social network characteristics, loneliness, and isolation by age group. RESULTS: Young adults reported twice as many days lonely and isolated than late middle-age adults, despite, paradoxically, having larger networks. For young adults, informal social participation and weekly religious attendance were associated with fewer days isolated. Among late middle-age adults, number of close kin and relationship status were associated with loneliness. Network satisfaction was associated with fewer days lonely or isolated among both age groups. CONCLUSION: Distinct network characteristics were associated with either loneliness or isolation for each cohort, suggesting network factors are independently associated with each outcome, and may fluctuate over time. Network satisfaction was associated with either loneliness or isolation among both cohorts, suggesting perceptions of social networks may be equally important as objective measures, and remain salient for loneliness and isolation throughout the life course. PMID- 29171765 TI - Serine protease inhibitors to treat inflammation: a patent review (2011-2016). AB - INTRODUCTION: Inflammation is a physiological part of the complex biological response of tissues to counteract various harmful signals. This process involves diverse actors such as immune cells, blood vessels, and nerves as sources of mediators for inflammation control. Among them serine proteases are key elements in both physiological and pathological inflammation. Areas covered: Serine protease inhibitors to treat inflammatory diseases are being actively investigated by various industrial and academic institutions. The present review covers patent literature on serine protease inhibitors for the therapy of inflammatory diseases patented between 2011 and 2016. Expert opinion: Serine proteases regulating inflammation are versatile enzymes, usually involved in proinflammatory cytokine production and activation of immune cells. Their dysregulation during inflammation can have devastating consequences, promoting various diseases including skin and lung inflammation, neuroinflammation, and inflammatory arthritis. Several serine proteases were selected for their contribution to inflammatory diseases and significant efforts that are spread to develop inhibitors. Strategies developed for inhibitor identification consist on either peptide-based inhibitor derived from endogenous protein inhibitors or small-organic molecules. It is also worth noting that among the recent patents on serine protease inhibitors related to inflammation a significant number are related to retinal vascular dysfunction and skin diseases.

AB - Type 2 diabetes mellitus, a disease which prevalence has been progressively increasing worldwide, is characterized by chronic hyperglycemia resulting from the combination of inappropriate insulin secretion and/or resistance to insulin action. If left uncontrolled, diabetes is associated with complications such as dysfunction and failure of various organs, and even premature death. Along with lifestyle-modification strategies, several classes of oral antidiabetic agents can be employed for glycemic control. Thus, therapeutic drug monitoring of these drugs is essential to maintain appropriate treatment. This review discusses the most frequently employed analytical techniques and sample preparation systems to obtain a reliable and trustworthy method to quantify antidiabetic drugs in biological matrices. An adequate choice of internal standard, ideal chromatography conditions and most suitable analytical detector are reported.

AB - INTRODUCTION: Alirocumab is a fully human immunoglobulin G1 monoclonal antibody directed against proprotein convertase subtilisin/kexin type 9 (PCSK9) approved for the treatment of hypercholesterolemia in high-risk patients. The objective is to provide an updated review of the recent data published for alirocumab. Areas covered: The efficacy and safety of alirocumab has been initially evaluated in a comprehensive phase 3 program conducted in more than 6 000 patients with primary non-familial and heterozygous familial hypercholesterolemia: alirocumab reduced LDL-cholesterol up to 62% in phase 3 with every 2-week dosing compared with placebo, and up to 36% compared with ezetimibe, with an excellent safety and tolerability profile. Herein, the author describes new efficacy and safety data obtained from complementary analyses of the phase 3 program submitted for approval and reports data from new specific trials. Expert commentary: Based on current high pricing, the patient groups prioritized for alirocumab treatment are patients with heterozygous familial hypercholesterolemia and patients with atherosclerotic cardiovascular disease who have substantially elevated LDL cholesterol on maximally tolerated statin plus ezetimibe therapy. The ongoing ODYSSEY OUTCOMES trial will provide important information on the cost effectiveness of alirocumab treatment. PMID- 29171770 TI - Emerging biomarkers of lymphangioleiomyomatosis. AB - INTRODUCTION: Lymphangioleiomyomatosis (LAM) is a destructive lung disease affecting primarily women. LAM is caused by inactivating mutations in the tuberous sclerosis complex (TSC) genes, resulting in hyperactivation of mechanistic/mammalian target of rapamycin complex 1 (mTORC1). Over the past five years, there have been remarkable advances in the diagnosis and therapy of LAM, including the identification of vascular endothelial growth factor D (VEGF-D) as a diagnostic biomarker and the US Food and Drug Administration approval of sirolimus as therapy for LAM. In appropriate clinical situations VEGF-D testing can make lung biopsy unnecessary to diagnose LAM. However, there remains an urgent unmet need for additional biomarkers of disease activity and/or response to therapy. Areas covered: This work reviews VEGF-D, an established LAM biomarker, and discusses emerging biomarkers, including circulating LAM cells, imaging, lipid, and metabolite biomarkers, focusing on those with the highest potential impact for LAM patients. Expert commentary: Ongoing research priorities include the development of validated biomarkers to 1) noninvasively diagnose LAM in women whose VEGF-D levels are not diagnostic, 2) accurately predict the likelihood of disease progression and 3) quantitatively measure disease activity and LAM cell burden. These biomarkers would enable personalized, precision clinical care and fast-track clinical trial implementation, with high clinical impact.

AB - AIM: To develop and validate an inductively coupled plasma-mass spectrometry method for quantitative bioanalysis of aluminum (Al) in monkey serum in support of a GLP TOX study with alhydrogel-formulated drug candidate. METHODS & RESULTS: The method was linear over a dynamic range of 10-1000 ng/ml using a 50-MUl sample volume. The intra-/inter-run precision (%CV) of the quality control sample results were <=7.9% (CV) and the accuracy (%bias) within +/-11.0% across all quality control concentrations evaluated. Other validation parameters, including stability under various conditions, extraction recovery and matrix effect, all met the acceptance criteria. CONCLUSION: The validated method was successfully implemented for the quantitative analysis of Al in monkey serum to assess the systemic exposure to Al. PMID- 29171772 TI - Assessing gaps in cholesterol treatment guidelines for primary prevention of cardiovascular disease based on available randomised clinical trial evidence: The Rotterdam Study. AB - Background The purpose of this study was to determine how American College of Cardiology/American Heart Association (ACC/AHA) 2013 and European Society of Cardiology 2016 guidelines for the primary prevention of atherosclerotic cardiovascular disease (CVD) compare in reflecting the totality of accrued randomised clinical trial evidence for statin treatment at population level. Methods From 1997-2008, 7279 participants aged 45-75 years, free of atherosclerotic cardiovascular disease, from the population-based Rotterdam Study were included. For each participant, we compared eligibility for each one of 11 randomised clinical trials on statin use in primary prevention of CVD, with recommendations on lipid-lowering therapy from the ACC/AHA and European Society of Cardiology (ESC) guidelines. Atherosclerotic cardiovascular disease incidence and cardiovascular disease mortality rates were calculated. Results The proportion of participants eligible for each trial ranged from 0.4% for ALLHAT LLT to 30.8% for MEGA. The likelihood of being recommended for lipid-lowering treatment was lowest for those eligible for low-to-intermediate risk RCTs (HOPE 3, MEGA, and JUPITER), and highest for high-risk individuals with diabetes (MRC/BHF HPS, CARDS, and ASPEN) or elderly PROSPER. Eligibility for an increasing number of randomised clinical trials correlated with a greater likelihood of being recommended lipid-lowering treatment by either guideline ( p < 0.001 for both guidelines). Conclusion Compared to RCTs done in high risk populations, randomised clinical trials targeting low-to-intermediate risk populations are less well-reflected in the ACC/AHA, and even less so in the ESC guideline recommendations. Importantly, the low-to-intermediate risk population targeted by HOPE-3, the most recent randomised clinical trial in this field, is not well captured by the current European prevention guidelines and should be specifically considered in future iterations of the guidelines. PMID- 29171773 TI - Fitness attenuates the prevalence of increased coronary artery calcium in individuals with metabolic syndrome. AB - Background The association between cardiorespiratory fitness, physical activity and coronary artery calcium (CAC) is unclear, and whether higher levels of fitness attenuate CAC prevalence in subjects with metabolic syndrome is not fully elucidated. The present study aims to: a) investigate the independent association of fitness on the prevalence of CAC, after adjustment for moderate-to-vigorous physical activity and sedentary time, and b) study the possible attenuation of increased CAC by higher fitness, in participants with metabolic syndrome. Design Cross-sectional. Methods In total 678 participants (52% women), 50-65 years old, from the SCAPIS pilot study were included. Fitness (VO2max) was estimated by submaximal cycle ergometer test and moderate-to-vigorous physical activity and sedentary time were assessed using hip-worn accelerometers. CAC score (CACS) was quantified using the Agatston score. Results The odds of having a significant CACS (>=100) was half in participants with moderate/high fitness compared with their low fitness counterparts. Further consideration of moderate-to-vigorous physical activity, sedentary time and number of components of the metabolic syndrome did only slightly alter the effect size. Those with metabolic syndrome had 47% higher odds for significant CAC compared with those without metabolic syndrome. However, moderate/high fitness seems to partially attenuate this risk, as further joint analysis indicated an increased odds for having significant CAC only in the unfit metabolic syndrome participants. Conclusions Being fit is associated with a reduced risk of having significant CAC in individuals with metabolic syndrome. While still very much underutilized, fitness should be taken into consideration in everyday clinical risk prediction in addition to the traditional risk factors of the metabolic syndrome. PMID- 29171774 TI - Advances in treating psoriasis in the elderly with small molecule inhibitors. AB - INTRODUCTION: Due to the chronic nature of psoriasis, the population of elderly psoriasis patients is increasing. However, many elderly psoriatic patients are not adequately treated because management is challenging as a result of comorbidities, polypharmacy, and progressive impairment of organ systems. Physicians may hesitate to use systemic or biologic agents in elderly psoriasis patients because of an increased risk of adverse events in this patient population. Small molecule medications are emerging as promising options for elderly patients with psoriasis and other inflammatory conditions. Areas covered: Here we review the efficacy, safety and tolerability of small molecule inhibitors apremilast, tofacitinib, ruxolitinib, baricitinib, and peficitinib in the treatment of psoriasis, with focus on their use in the elderly population. Expert opinion: Although small molecule inhibitors demonstrate efficacy in elderly patients with psoriasis, they will require larger head-to-head studies and post marketing registries to evaluate their effectiveness and safety in specific patient populations. Apremilast, ruxolitinib, and peficitinib are effective agents with favorable side effect profiles; however, physicians should exercise caution when prescribing tofacitinib or baricitinib in elderly populations due to adverse events. The high cost of these drugs in the U.S. is likely to limit their use. PMID- 29171775 TI - Acute high-fat feeding leads to disruptions in glucose homeostasis and worsens stroke outcome. AB - Chronic consumption of diets high in fat leads to obesity and can negatively affect brain function. Rodents made obese by long-term maintenance on a high-fat diet have worse outcome after experimental stroke. High-fat consumption for only three days does not induce obesity but has rapid effects on the brain including memory impairment. However, the effect of brief periods of high-fat feeding or high-fat consumption in the absence of obesity on stroke is unknown. We therefore tested the effect of an acute period of high-fat feeding (three days) in C57B/6 mice on outcome after middle cerebral artery occlusion (MCAo). In contrast to a chronic high-fat diet (7.5 months), an acute high-fat diet had no effect on body weight, adipose tissue, lipid profile or inflammatory markers (in periphery and the brain). Three days of high-fat feeding impaired glucose tolerance, increased plasma glucose and insulin and brain expression of the glucose transporter GLUT 1. Ischaemic damage was increased (48%) in mice fed an acute high-fat diet, and was associated with a further reduction in GLUT-1 in the ischaemic hemisphere. These data demonstrate that only a brief period of high-fat consumption has a negative effect on glucose homeostasis and worsens outcome after ischaemic stroke.

PMID- 29171776 TI - Extended thromboprophylaxis in the acutely ill medical patient after hospitalization - a paradigm shift in post-discharge thromboprophylaxis. AB - Venous thromboembolism (VTE) is a significant healthcare burden with approximately 900,000 events annually in the United States, over half of which are healthcare-associated. This number is anticipated to double by 2050. Group prophylaxis strategies confined to the inpatient setting appear to have minimal impact on the reduction of post-discharge VTE in medically ill patients due to shortened lengths of stay and a heterogenous population that includes patients at low risk for VTE. In accordance with current guideline recommendations, very few (<5%) medically ill patients are discharged with extended prophylaxis, which potentially creates a clinical gap for at-risk patients as VTE risk has been shown to persist for up to 90 days. Initial studies of extended thromboprophylaxis in acutely ill medical patients with enoxaparin, rivaroxaban and apixaban showed little to no benefit towards VTE reduction that was consistently outweighed by increased bleeding. The more recent APEX study that compared betrixaban to enoxaparin in an enriched patient population at high-risk for VTE was the first study of extended thromboprophylaxis that showed similar efficacy in VTE prevention without an increase in major bleeding. Based on the APEX results, betrixaban recently gained FDA approval for extended thromboprophylaxis in acutely ill medical patients. Recognition that up to half of medically ill patients are not at sufficient risk to warrant thromboprophylaxis has driven extensive research towards development of scientifically derived and validated VTE risk assessment models intended to identify patients who do not warrant prophylaxis, as well as those at high risk who may derive benefit from extended thromboprophylaxis. This article will review prior and ongoing extended thromboprophylaxis studies, VTE and bleed risk assessment models, incorporation of biomarkers in VTE risk assessment and key issues in the paradigm shift towards individualized VTE prophylaxis in acutely ill medical patients.

AB - Oral insulin administration is limited due to its degradation by proteases. The hormone was encapsulated in spheres made of either pure calcium alginate (ALG) or its association with whey protein isolate (WPI-ALG) in order to minimise loss in the stomach region while allowing liberation in the maximum absorption area, located in the intestine. Diffusion coefficients for both matrix compositions were determined in vitro for gastric pH (5.88 and 10.26 * 10-12 m2 s-1) and intestinal pH (21.11 and 79.29 * 10-12 m2 s-1). Higher initial insulin concentrations and lower diameters accelerated its release, confirming Fickian behaviour. The analytic model exhibited a good fit in most cases. Computer simulations revealed that ALG spheres are more convenient for oral administration because they release more insulin in the intestine than the WPI-ALG ones, thus supporting its therapeutic viability for the purpose of reducing stress in those who depend on insulin.

AB - Objective The progressive rise in demand on NHS emergency care resources is partly attributable to increases in attendances of children and older people. A quality gap exists in the care provision for the old and the young. The Five Year Forward View suggested new models of care but that the "answer is not one-size fits-all". This article discusses the urgent need for person-centred outcome measures to bridge the gap that exists between demand and provision. Design This review is based on evidence gathered from literature searching across several platforms using a variety of search terms to account for the obvious heterogeneity, drawing on key 'think-tank' evidence. Settings Qualitative and quantitative studies examining approaches to caring for individuals at the extremes of age. Participants Individuals at the extremes of age (infants and older people). Main Outcome Measures Understanding similarities and disparities in the care of individuals at the extremes of age in an emergency and non emergency context. Results There exists several similarities and disparities in the care of individuals at the extremes of age. The increasing burden of health disease on the economy must acknowledge the challenges that exist in managing patients in emergency settings at the extremes of age and build systems to acknowledge the traits these individuals exhibit. Conclusion Commissioners of services must optimise the models of care delivery by appreciating the similarities and differences between care requirements in these two large groups seeking emergency care.

AB - While staying in the White House over Christmas 1941, Churchill developed chest pain on trying to open a window in his bedroom. Sir Charles Wilson, his personal physician, diagnosed a 'heart attack' (myocardial infarction). Wilson, for political and personal reasons, decided not to inform his patient of the diagnosis or obtain assistance from US medical colleagues. On Churchill's return to London, Wilson sought a second opinion from Dr John Parkinson who did not support the diagnosis of coronary thrombosis (myocardial infarction) and reassured Churchill accordingly.

PMID- 29171783 TI - Hyperhomocysteinemia-induced autophagy and apoptosis with downregulation of hairy enhancer of split 1/5 in cortical neurons in mice. AB - It has been reported that hyperhomocysteinemia (HHcy) is associated with neurodegenerative and cardiovascular diseases. However, little is known about brain histomorphology, neuronal organelles, and hairy enhancer of split ( hes) expression under HHcy. In this study, non-HHcy and HHcy induced by high methionine diet in apolipoprotein E-deficient (Apo E-/-) mice were comparatively investigated. The histomorphology, ultrastructure, autophagosomes, apoptosis, and expression of proteins, HES1, HES5 and P62, were designed to assess the effects of HHcy on brain. The results showed that compared to the non-HHcy mice, the HHcy group had an increase in autophagosomes, vacuolization in mitochondria, and neuron apoptosis; treatment with folate and vitamin B12 reduced the extent of these lesions. However, the elementary histomorphology, the numbers of cortical neurons, and Nissl bodies had no significant difference between the HHcy and the non-HHcy groups or the group treated with folate and vitamin B12. Immunohistochemistry and immunofluorescence demonstrated a decrease in HES1- or HES5-positive neurons in the HHcy group when compared to the non-HHcy groups, wild-type, and Apo E-/- controls, or the HHcy mice with folate and vitamin B12 supplement. Western blots showed that HHcy induced a decreased expression of HES1 and HES5, or P62, in which the expression of HES1 and P62 was elevated by treating with folate and vitamin B12 supplement. These results suggest that HHcy enhanced brain damage is associated with increased autophagy and neuronal apoptosis in Apo E-/- mice, in which downregulation of hes1 and hes5 is involved. PMID- 29171784 TI - Necroptosis promotes autophagy-dependent upregulation of DAMP and results in immunosurveillance. AB - Programmed necrosis, necroptosis, is considered to be a highly immunogenic activity, often mediated via the release of damage-associated molecular patterns (DAMPs). Interestingly, enhanced macroautophagic/autophagic activity is often found to be accompanied by necroptosis. However, the possible role of autophagy in the immunogenicity of necroptotic death remains largely obscure. In this study, we investigated the possible mechanistic correlation between phytochemical shikonin-induced autophagy and the shikonin-induced necroptosis for tumor immunogenicity. We show that shikonin can instigate RIPK1 (receptor [TNFRSF] interacting serine-threonine kinase 1)- and RIPK3 (receptor-interacting serine threonine kinase 3)-dependent necroptosis that is accompanied by enhanced autophagy. Shikonin-induced autophagy can directly contribute to DAMP upregulation. Counterintuitively, among the released and ectoDAMPs, only the latter were shown to be able to activate the cocultured dendritic cells (DCs). Interruption of autophagic flux via chloroquine further upregulated ectoDAMP activity and resultant DC activation. For potential clinical application, DC vaccine preparations treated with tumor cells that were already pretreated with chloroquine and shikonin further enhanced the antimetastatic activity of 4T1 tumors and reduced the effective dosage of doxorubicin. The enhanced immunogenicity and vaccine efficacy obtained via shikonin and chloroquine cotreatment of tumor cells may thus constitute a compelling strategy for developing cancer vaccines via the use of a combinational drug treatment. PMID- 29171786 TI - Bidirectional Regulation of Genistein on the Proliferation and Differentiation of C2C12 Myoblasts. AB - 1. Genistein is a widely studied phytoestrogen. The effects of genistein on myoblasts were reported long ago, but the conclusions are controversial. In the current study, we evaluated the effects of different concentrations of genistein on C2C12 myoblasts. 2. Genistein treatment promoted myoblast proliferation in a dose-development manner in the 0-2 uM/L range, reaching its maximum effect at 2 uM/L. Proliferation then declined, and a concentration higher than 20 uM/L showed significant inhibition. Additionally, genistein treatment promoted myoblast differentiation at a dose of 10 uM/L. However, at treatment concentrations higher than 10 uM/L, the effect on myoblast differentiation was rapidly inhibited as the concentration increased. 3. Genistein treatment also downregulated miR-222, resulting in increased expression of its target genes, MyoG, MyoD and ERalpha and thereby promoting myoblast differentiation. 4. Our results suggest that genistein has a dose-dependent and bidirectional regulation effect on myoblast proliferation and differentiation. We also found that genistein is a miRNA inducer, and it specifically affects the expression of miR-222 to regulate myoblast differentiation.

AB - Scanning Wizard software helps scanning users improve the setup of their switch and scanning system. This study evaluated Scanning Wizard's effectiveness and usability. Ten people who use switch scanning and ten practitioners used Scanning Wizard in the initial session. Usability was high, based on survey responses averaging over 4.5 out of 5, and qualitative feedback was very positive. Five switch users were able to complete the multi-week protocol, using settings on their own scanning system that were recommended from the Scanning Wizard session. Using these revised settings, text entry rates improved by an average of 71%, ranging from 29% to 172% improvement. Results suggest that Scanning Wizard is a useful tool for improving the configuration of scanning systems for people who use switch scanning to communicate. Implications for Rehabilitation Some individuals with severe physical impairments use switch scanning for spoken and written communication. Scanning Wizard software helps scanning users improve the setup of their switch and scanning system. This study demonstrated high usability of Scanning Wizard (with 10 switch userpractitioner teams) and increased text entry rate by an average of 71% (for five switch users). Results suggest that Scanning Wizard is a useful tool for improving the configuration of scanning systems for people who use switch scanning to communicate. PMID- 29171785 TI - Regulation of RNA polymerase III transcription during transformation of human IMR90 fibroblasts with defined genetic elements. AB - RNA polymerase (Pol) III transcribes small untranslated RNAs that are essential for cellular homeostasis and growth. Its activity is regulated by inactivation of tumor suppressor proteins and overexpression of the oncogene c-MYC, but the concerted action of these tumor-promoting factors on Pol III transcription has not yet been assessed. In order to comprehensively analyse the regulation of Pol III transcription during tumorigenesis we employ a model system that relies on the expression of five genetic elements to achieve cellular transformation. Expression of these elements in six distinct transformation intermediate cell lines leads to the inactivation of TP53, RB1, and protein phosphatase 2A, as well as the activation of RAS and the protection of telomeres by TERT, thereby conducting to full tumoral transformation of IMR90 fibroblasts. Transformation is accompanied by moderately enhanced levels of a subset of Pol III-transcribed RNAs (7SK; MRP; H1). In addition, mRNA and/or protein levels of several Pol III subunits and transcription factors are upregulated, including increased protein levels of TFIIIB and TFIIIC subunits, of SNAPC1 and of Pol III subunits. Strikingly, the expression of POLR3G and of SNAPC1 is strongly enhanced during transformation in this cellular transformation model. Collectively, our data indicate that increased expression of several components of the Pol III transcription system accompanied by a 2-fold increase in steady state levels of a subset of Pol III RNAs is sufficient for sustaining tumor formation. PMID- 29171788 TI - Endovascular retrieval of a migrating pedicle screw within the inferior vena cava after instrumented spinal surgery: case report. AB - During L3-5 instrumented spinal surgery for degenerative spondylolisthesis in a 75-year-old woman, the right L-3 pedicle screw was accidentally pushed into the retroperitoneum and then migrated to the inferior vena cava (IVC). The patient was transferred to the surgical intensive care unit, and after careful discussion with cardiology specialists, a minimally invasive endovascular technique was used to remove the migrating pedicle screw within the IVC and thus salvage this critical case. Pedicle screw instrumentation is an effective procedure, but not risk free. Every detail should be scrutinized during surgery, even instrument construction. A minimally invasive endovascular technique should be considered in this patient population. PMID- 29171789 TI - Accuracy of identification of low or high risk lifting during standardised lifting situations. AB - The aim was to classify lifting activities into low and high risk categories (according to The Danish Working Environment Authority guidelines) based on surface electromyography (sEMG) and trunk inclination (tri-axial accelerometer) measurements. Lifting tasks with different weights, horizontal distance and technique were performed. The lifting tasks were characterised by a feature vector composed of either the 90th, 95th or 99th percentile of sEMG activity level and trunk inclinations during the task. Linear Discriminant Analysis and a subject-specific threshold scheme were applied and lifting tasks were classified with an accuracy of 65.1-65.5%. When lifts were classified based on the subject specific threshold scheme from low and upper back accelerometers, the accuracy reached 52.1-58.1% and 72.7-78.1%, respectively. In conclusion, the use of subject-specific thresholds from sEMG from upper trapezius and erector spinae as well as inclination of the upper trunk enabled us to identify low and high risk lifts with an acceptable accuracy. Practitioner Summary: This study contributes to the development of a method enabling the automatic detection of high risk lifting tasks, i.e. exposure to high biomechanical loads, based on individual sEMG and kinematics from an entire working day. These methods may be more cost effective and may complement observations commonly used by practitioners. PMID- 29171790 TI - Transcriptomic Analysis of Arabidopsis Seedlings in Response to an Agrobacterium Mediated Transformation Process. AB - Agrobacterium tumefaciens is a plant pathogen that causes crown gall disease. This pathogen is capable of transferring the T-DNA from its Ti plasmid to the host cell and, then, integrating it into the host genome. To date, this genetic transformation ability has been harnessed as the dominant technology to produce genetically modified plants for both basic research and crop biotechnological applications. However, little is known about the interaction between Agrobacterium tumefaciens and host plants, especially the host responses to Agrobacterium infection and its associated factors. We employed RNA-seq to follow the time course of gene expression in Arabidopsis seedlings infected with either an avirulent or a virulent Agrobacterium strain. Gene Ontology analysis indicated many biological processes were involved in the Agrobacterium-mediated transformation process, including hormone signaling, defense response, cellular biosynthesis, and nucleic acid metabolism. RNAseq and quantitative reverse transcription-polymerase chain reaction results indicated that expression of genes involved in host plant growth and development were repressed but those involved in defense response were induced by Agrobacterium tumefaciens. Further analysis of the responses of transgenic Arabidopsis lines constitutively expressing either the VirE2 or VirE3 protein suggested Vir proteins act to enhance plant defense responses in addition to their known roles facilitating T DNA transformation. PMID- 29171791 TI - Voice and swallowing outcomes following reoperative anterior cervical discectomy and fusion with a 2-team surgical approach. AB - OBJECTIVE Dysphagia and vocal cord palsy (VCP) are common complications after anterior cervical discectomy and fusion (ACDF). The reported incidence rates for dysphagia and VCP are variable. When videolaryngostroboscopy (VLS) is performed to assess vocal cord function after ACDF procedures, the incidence of VCP is reported to be as high as 22%. The incidence of dysphagia ranges widely, with estimates up to 71%. However, to the authors' knowledge, there are no prospective studies that demonstrate the rates of VCP and dysphagia for reoperative ACDF. This study aimed to investigate the incidence of voice and swallowing disturbances before and after reoperative ACDF using a 2-team operative approach with comprehensive pre- and postoperative assessment of swallowing, direct vocal cord visualization, and clinical neurosurgical outcomes. METHODS A convenience sample of sequential patients who were identified as requiring reoperative ACDF by the senior spinal neurosurgeon at the University of Alabama at Birmingham were enrolled in a prospective, nonrandomized study during the period from May 2010 until July 2014. Sixty-seven patients undergoing revision ACDF were enrolled using a 2-team approach with neurosurgery and otolaryngology. Dysphagia was assessed both preoperatively and postoperatively using the MD Anderson Dysphagia Inventory (MDADI) and fiberoptic endoscopic evaluation of swallowing (FEES), whereas VCP was assessed using direct visualization with VLS. RESULTS Five patients (7.5%) developed a new postoperative temporary VCP after reoperative ACDF. All of these cases resolved by 2 months postoperatively. There were no new instances of permanent VCP. Twenty-five patients had a new swallowing disturbance detected on FEES compared with their baseline assessment, with most being mild and requiring no intervention. Nearly 60% of patients showed a decrease in their postoperative MDADI scores, particularly within the physical subset. CONCLUSIONS A 2-team approach to reoperative ACDF was safe and effective, with no new cases of VCP on postoperative VLS. Dysphagia rates as assessed through the MDADI scale and FEES were consistent with other published reports. PMID- 29171792 TI - Preparation and characteristics of the sulfonated chitosan derivatives electrodeposited onto 316l stainless steel surface. AB - In order to ameliorate the properties of corrosion resistance and achieve applications in anti-biofouling of 316L stainless steel (SS), a sulfated derivative of chitosan was deposited onto stainless steel surface by an electrochemical method. In detail, chitosan-catechol (CS-CT) was synthesised in the hydrochloric acid solution by the Mannich reaction and then electrodeposited on the surface of the polished 316L stainless steel. The chitosan-catechol deposited SS sample was further modified with maleic anhydride and sulfite. The grafting progress was monitored by FTIR, UV spectrophotometer and X-ray photoelectron spectroscopy. Hydrophilicity and corrosion resistance of modified SS were characterized by water contact angle measurements, Tafel curves and electrochemical impedance spectroscopy. The morphology of the SS surface before and after the modification was investigated by atomic force microscopy and scanning electron microscope. Further, the anti-biofouling performance in terms of the anti-adsorption protein and anti-bacteria effects of all modified SS samples were estimated, and the modified 316L exhibits the capability of lower protein adsorption and improved antibacterial effect. PMID- 29171793 TI - Preoperative skin antisepsis with chlorhexidine gluconate versus povidone-iodine: a prospective analysis of 6959 consecutive spinal surgery patients. AB - OBJECTIVE The aim of this study was to determine the efficacy of 2 common preoperative surgical skin antiseptic agents, ChloraPrep and Betadine, in the reduction of postoperative surgical site infection (SSI) in spinal surgery procedures. METHODS Two preoperative surgical skin antiseptic agents-ChloraPrep (2% chlorhexidine gluconate and 70% isopropyl alcohol) and Betadine (7.5% povidone-iodine solution)-were prospectively compared across 2 consecutive time periods for all consecutive adult neurosurgical spine patients. The primary end point was the incidence of SSI. RESULTS A total of 6959 consecutive spinal surgery patients were identified from July 1, 2011, through August 31, 2015, with 4495 (64.6%) and 2464 (35.4%) patients treated at facilities 1 and 2, respectively. Sixty-nine (0.992%) SSIs were observed. There was no significant difference in the incidence of infection between patients prepared with Betadine (33 [1.036%] of 3185) and those prepared with ChloraPrep (36 [0.954%] of 3774; p = 0.728). Neither was there a significant difference in the incidence of infection in the patients treated at facility 1 (52 [1.157%] of 4495) versus facility 2 (17 [0.690%] of 2464; p = 0.06). Among the patients with SSI, the most common indication was degenerative disease (48 [69.6%] of 69). Fifty-one (74%) patients with SSI had undergone instrumented fusions in the index operation, and 38 (55%) patients with SSI had undergone revision surgeries. The incidence of SSI for minimally invasive and open surgery was 0.226% (2 of 885 cases) and 1.103% (67 of 6074 cases), respectively. CONCLUSIONS The choice of either ChloraPrep or Betadine for preoperative skin antisepsis in spinal surgery had no significant impact on the incidence of postoperative SSI.

AB - In this study, potential microalgae species (Chlorella vulgaris, Scenedesmus dimorphus, Chlorococcum sp. and Chlamydomonas sp.) have been studied for nutrient removal from synthetic and industrial wastewater. Batch experiments were carried out to investigate the removal performance among four chosen species at different nitrogen and phosphorus concentrations. NH4-N and PO4-P were varied from 13.2 to 52.8 mg/L and 6.6 to 26.4 mg/L, respectively, by keeping N:P ratio as 2:1. In synthetic wastewater, maximum NH4-N and PO4-P removal efficiencies of 88.6% and 91.2% were obtained with C. vulgaris when compared to the other microalgae studied. Further studies were carried out using C. vulgaris in batch experiments to investigate the nutrient removal performance in secondary treated sewage, soak liquor and composite tannery effluent. Experimental results indicated that NH4-N, NO3-N, PO4-P and chemical oxygen demand (COD) removal efficiencies were found to be 68.6%, 74%, 71.5% and 90.2%, respectively, in secondary treated sewage. Maximum removal efficiencies of NH4-N, NO3-N, PO4-P and COD in composite tannery wastewater were found to be 55%, 85.6%, 60.5% and 43.4%, respectively. In soak liquor, maximum removal efficiencies of NH4-N, NO3-N, PO4-P and COD were found to 66.7%, 62.6%, 63.6% and 93.8%, respectively. PMID- 29171795 TI - Young men's rationales for non-exclusive gay sexualities. AB - Recent evidence suggests it is useful to distinguish sexual identities among young men at the gay end of the spectrum because of group differences between primarily gay, mostly gay and gay orientations on several assessed physiological, behavioural and self-report measures. However, little is known about individuals' rationales for choosing sexuality labels beyond traditional gay or bisexual categories. We addressed this issue by interviewing 24 young men with a non exclusive gay orientation about their sexual desires and histories, drawing on both qualitative and numeric data. Undertaking an inductive analysis, we found four distinct rationales for identification with a sexual orientation label: sexual, romantic, intellectual and internalised homophobia. By examining what young men mean when they classify themselves as primarily gay, mostly gay or bisexual-leaning gay, this article provides data to understand these issues and proposes that greater focus should be placed on sexual identity for non-exclusive gay men. Although the sexual and affectional components of sexual orientation are meaningful, previous research has not sufficiently accounted for the importance of intellectual, cultural and romantic factors in non-exclusive sexual orientations. To address these issues, the use of in-depth interviews should be incorporated in future studies. PMID- 29171796 TI - 'He's not my pimp': toward an understanding of intimate male partner involvement in female sex work at the Mexico-US border. AB - Female sex work is often perceived as women being controlled by men. We used surveys and qualitative interviews with female sex workers and their intimate partners in two Northern Mexico cities to examine couples' own perceptions of their relationships and male partners' involvement in sex work. Among 214 couples, the median age was 34 and relationship duration was approximately 3 years. Only 10 women in the survey reported having a pimp, and the majority reported sole control over sex work decisions. Qualitative analyses revealed that while most men avoided direct involvement in sex work, they offered advice that was largely driven by concern for their partner's well-being. Our discussion of these results considers the broader socio-political context surrounding these relationships and how changing gender roles, economic insecurity and stigma shape couples' everyday social interactions. Assumptions that all sex workers' relationships are coercive and commercial marginalises these couples while leaving their health concerns unaddressed. PMID- 29171797 TI - Health-related quality of life outcomes in complex adult spinal deformity surgery. AB - OBJECTIVE Significant health-related quality of life (HRQOL) benefits have been observed for patients undergoing primary and revision adult spinal deformity (ASD) surgery. The purpose of this study was to report changes in HRQOL measures in a consecutive series of patients undergoing complex spinal reconstructive surgery, using Scoli-RISK-1 (SR-1) inclusion criteria. METHODS This was a single center, retrospective cohort study. The SR-1 inclusion criteria were used to define patients with complex ASD treated between June 1, 2009, and June 1, 2011. Standard preoperative and perioperative data were collected, including the Scoliosis Research Society (SRS)-22r instrument. The HRQOL changes were evaluated at a minimum 2-year follow-up. Standardized forms were used to collect surgery related complications data for all patients. Complications were defined as minor, transient major, or permanent major. Patients who achieved a minimum 2-year follow-up were included in the analysis. RESULTS Eighty-four patients meeting SR 1 criteria were identified. Baseline demographic and surgical data were available for 74/84 (88%) patients. Forty-seven of 74 (64%) patients met the additional HRQOL criteria with a minimum 2-year follow-up (mean follow-up 3.4 years, range 2 6.5 years). Twenty-one percent of patients underwent posterior fusion only, 40% of patients had a posterior column osteotomy, and 38% had a 3-column osteotomy. Seventy-five percent of patients underwent a revision procedure. Significant improvements were observed in all SRS-22r domains: Pain: +0.8 (p < 0.001); Self Image: +1.4 (p < 0.001); Function: +0.46 (p < 0.001); Satisfaction: +1.6 (p < 0.001); and Mental Health: +0.28 (p = 0.04). With the exception of Mental Health, more than 50% of patients achieved a minimum clinically important difference (MCID) in SRS-22r domain scores (Mental Health: 20/47, 42.6%). A total of 65 complications occurred in 31 patients. This includes 29.8% (14/47) of patients who suffered a major complication and 17% (8/47) who suffered a postoperative neurological deficit, most commonly at the root level (10.6%, 5/47). Of the 8 patients who suffered a neurological deficit, 1 (13%) was able to achieve MCID in the SRS Function domain. CONCLUSIONS The majority of patients experienced clinically relevant improvement in SRS-22r HRQOL scores after complex ASD surgery. The greatest improvements were seen in the SRS Pain and SRS Self-Image domains. Although 30% of patients suffered a major or permanent complication, benefits from surgery were still attained. Patients sustaining a neurological deficit or major complication were unlikely to achieve HRQOL improvements meeting or exceeding MCID for the SRS Function domain. PMID- 29171798 TI - Orbital lymphatic-venous malformation with concomitant spontaneous orbital arteriovenous fistula: case report. AB - The authors describe the case of an 11-year-old boy with no history of prior trauma, who experienced acute proptosis and visual loss while showering. Diagnostic carotid artery angiography revealed an orbital lymphatic-venous malformation (LVM) concomitant with an intraorbital arteriovenous fistula. The patient was treated with transvenous coil and N-butyl cyanoacrylate glue embolization, combined with direct percutaneous glue injection into the LVM followed by excision. There was good clinical and radiological response without recurrence at the 2-year follow-up. Diagnostic carotid angiography should be considered in cases of orbital LVM, as a concomitant arteriovenous fistula might be present in rare cases. PMID- 29171799 TI - Surgical management of cerebellopontine angle arachnoid cysts associated with hearing deficit in pediatric patients. AB - OBJECTIVE Few cases of cerebellopontine angle (CPA) arachnoid cysts in pediatric patients have been described in the literature, and in only 2 of these cases were the patients described as suffering from hearing deficit. In this article, the authors report on 3 pediatric patients with CPA arachnoid cysts (2 with hearing loss and 1 with recurrent headaches) who underwent neurosurgical treatment at the authors' institution. METHODS Four pediatric patients were diagnosed with CPA arachnoid cysts at the International Neuroscience Institute during the period from October 2004 through August 2012, and 3 of these patients underwent surgical treatment. The authors describe the patients' clinical symptoms, the surgical approach, and the results on long-term follow-up. RESULTS One patient (age 14 years) who presented with headache (without hearing deficit) became asymptomatic after surgical treatment. The other 2 patients who underwent surgical treatment both had hearing loss. One of these children (age 9 years) had recent-onset hypacusia and experienced complete recovery immediately after the surgery. The other (age 6 years) had a longer history (2 years) of progressive hearing loss and showed an interruption of the deficit progression and only mild improvement at the follow-up visit. CONCLUSIONS CPA arachnoid cysts are uncommon in pediatric patients. The indication and timing of the surgical treatment are fundamental, especially when a hearing deficit is present. PMID- 29171800 TI - Chiari-related scoliosis: a single-center experience with long-term radiographic follow-up and relationship to deformity correction. AB - OBJECTIVE Previous reports have addressed the short-term response of patients with Chiari-related scoliosis (CRS) to suboccipital decompression and duraplasty (SODD); however, the long-term behavior of the curve has not been well defined. The authors undertook a longitudinal study of a cohort of patients who underwent SODD for CRS to determine whether there are factors related to Chiari malformation (CM) that predict long-term scoliotic curve behavior and need for deformity correction. METHODS The authors retrospectively reviewed cases in which patients underwent SODD for CRS during a 14-year period at a single center. Clinical (age, sex, and associated disorders/syndromes) and radiographic (CM type, tonsillar descent, pBC2 line, clival-axial angle [CXA], syrinx length and level, and initial Cobb angle) information was evaluated to identify associations with the primary outcome: delayed thoracolumbar fusion for progressive scoliosis. RESULTS Twenty-eight patients were identified, but 4 were lost to follow-up and 1 underwent fusion within a year. Among the remaining 23 patients, 11 required fusion surgery at an average of 88.3 +/- 15.4 months after SODD, including 7 (30%) who needed fusion more than 5 years after SODD. On univariate analysis, a lower CXA (131.5 degrees +/- 4.8 degrees vs 146.5 degrees +/- 4.6 degrees , p = 0.034), pBC2 > 9 mm (64% vs 25%, p = 0.06), and higher initial Cobb angle (35.1 degrees +/- 3.6 degrees vs 22.8 degrees +/- 4.0 degrees , p = 0.035) were associated with the need for thoracolumbar fusion. Multivariable modeling revealed that lower CXA was independently associated with a need for delayed thoracolumbar fusion (OR 1.12, p = 0.0128). CONCLUSIONS This investigation demonstrates the long-term outcome and natural history of CRS after SODD. The durability of the effect of SODD on CRS and curve behavior is poor, with late curve progression occurring in 30% of patients. Factors associated with CRS progression include an initial pBC2 > 9 mm, lower CXA, and higher Cobb angle. Lower CXA was an independent predictor of delayed thoracolumbar fusion. Further study is necessary on a larger cohort of patients to fully elucidate this relationship. PMID- 29171801 TI - Intraoperative and postoperative complications in the surgical treatment of craniosynostosis: minimally invasive versus open surgical procedures. AB - OBJECTIVE To compare minimally invasive endoscopic and open surgical procedures, to improve informed consent of parents, and to establish a baseline for further targeted improvement of surgical care, this study evaluated the complication rate and blood transfusion rate of craniosynostosis surgery in our department. METHODS A prospective complication registration database that contains a consecutive cohort of all pediatric neurosurgical procedures in the authors' neurosurgical department was used. All pediatric patients who underwent neurosurgical treatment for craniosynostosis between February 2004 and December 2014 were included. In total, 187 procedures were performed, of which 121 were endoscopically assisted minimally invasive procedures (65%). Ninety-three patients were diagnosed with scaphocephaly, 50 with trigonocephaly, 26 with plagiocephaly, 3 with brachycephaly, 9 with a craniosynostosis syndrome, and 6 patients were suffering from nonsyndromic multisutural craniosynostosis. RESULTS A total of 18 complications occurred in 187 procedures (9.6%, 95% CI 6.2-15), of which 5.3% (n = 10, 95% CI 2.9-10) occurred intraoperatively and 4.2% (n = 8, 95% CI 2.2-8.2) occurred postoperatively. In the open surgical procedure group, 9 complications occurred: 6 intraoperatively and 3 postoperatively. In the endoscopically assisted procedure group, 9 complications occurred: 4 intraoperatively and 5 postoperatively. Blood transfusion was needed in 100% (n = 66) of the open surgical procedures but in only 21% (n = 26, 95% CI 15-30) of the endoscopic procedures. One patient suffered a transfusion reaction, and 6 patients suffered infections, only one of which was a surgical site infection. A dural tear was the most common intraoperative complication that occurred (n = 8), but it never led to postoperative sequelae. Intraoperative bleeding from a sagittal sinus occurred in one patient with only minimal blood loss. There were no deaths, permanent morbidity, or neurological sequelae. CONCLUSIONS Complications during craniosynostosis surgery were relatively few and minor and were without permanent sequelae in open and in minimally invasive procedures. The blood transfusion rate was significantly reduced in endoscopic procedures compared with open procedures. PMID- 29171803 TI - Letter to the Editor. Puzzling posology: was the bevacizumab regimen in recurrent glioblastoma misreported? PMID- 29171802 TI - Is the chiasm-pituitary corridor size important for achieving gross-total resection during endonasal endoscopic resection of craniopharyngiomas? AB - OBJECTIVE Craniopharyngiomas arise from the pituitary stalk, and in adults they are generally located posterior to the chiasm extending up into the third ventricle. The extended endonasal approach (EEA) can provide an ideal corridor between the bottom of the optic chiasm and the top of the pituitary gland (chiasm pituitary corridor [CPC]) for their removal. A narrow CPC in patients with a prefixed chiasm and a large tumor extending up and behind the chiasm has been considered a contraindication to EEA, with a high risk of visual deterioration and subtotal resection. METHODS A database of all patients treated in the authors' center (Weill Cornell Medical College, NewYork-Presbyterian Hospital) between July 2004 and August 2016 was reviewed. Patients with craniopharyngiomas who underwent EEA with the goal of gross-total resection (GTR) were included in the study. Patients with postfixed chiasm or limited available preoperative imaging were excluded. Using preoperative contrast-enhanced T1-weighted sagittal midline MR images, the authors calculated the CPC as well as the distance from the chiasm to the top of the tumor (CTOT). From these numbers, they calculated a ratio of the CPC to the CTOT as a measure of difficulty in removing the tumors through the EEA and called this ratio the corridor index (CI). The relationship between the CI and the ability to achieve GTR and visual outcome were measured. RESULTS Thirty-four patients were included in the study. The mean CPC was 10.1 mm (range 5.2-19.1 mm). The mean CTOT was 12.8 mm (range 0-28.3 mm). The median CI was 0.8; the CI ranged from 0.4 to infinity (for tumors with a CTOT of 0). Thirty two patients had GTR (94.1%) and 2 had subtotal resection. The CPC value had no relationship with our ability to achieve GTR and no effect on visual or endocrine outcome. CONCLUSIONS EEA for craniopharyngioma is generally considered the first line surgical approach. Although a narrow corridor between the top of the pituitary gland and the bottom of the chiasm may seem to be a relative contraindication to surgery for larger tumors, the authors' data do not bear this out. EEA appears to be a successful technique for the majority of midline craniopharyngiomas. PMID- 29171805 TI - Erratum.

AB - Intraoperative 3D recognition of the motor tract is indispensable to avoiding neural fiber injury in brain tumor surgery. However, precise localization of the tracts is sometimes difficult with conventional mapping methods. Thus, the authors developed a novel brain mapping method that enables the 3D recognition of the motor tract for intrinsic brain tumor surgeries. This technique was performed in 40 consecutive patients with gliomas adjacent to motor tracts that have a risk of intraoperative pyramidal tract damage. Motor tracts were electrically stimulated and identified by a handheld brain-mapping probe, the NY Tract Finder (NYTF). Sixteen-gauge plastic tubes were mounted onto the NYTF and inserted in the estimated direction of the motor tract with reference to navigational information. Only the NYTF was removed, leaving the plastic tubes in their places, immediately after muscle motor evoked potentials were recorded at the minimum stimulation current. Motor tracts were electrically identified in all cases. Three-dimensional information on the position of motor tracts was given by plastic tubes that were neurophysiologically placed. Tips of tubes showed the resection limit during tumor removal. Safe tumor resection with an arbitrary safety margin can be performed by adjusting the length of the plastic tubes. The motor tract positioning method enabled the 3D recognition of the motor tract by surgeons and provided for safe resection of tumors. Tumor resections were performed safely before damaging motor tracts, without any postoperative neurological deterioration. PMID- 29171806 TI - Letter to the Editor. Computed tomography angiography in brain death determination: is there justification for its use? PMID- 29171807 TI - The venous delay phenomenon in computed tomography angiography: a novel imaging outcome predictor for poor cerebral perfusion after severe aneurysmal subarachnoid hemorrhage. AB - OBJECTIVE: Diverse treatment results are observed in patients with poor-grade aneurysmal subarachnoid hemorrhage (aSAH). Significant initial perfusion compromise is thought to predict a worse treatment outcome, but this has scant support in the literature. In this cohort study, the authors correlate the treatment outcomes with a novel poor-outcome imaging predictor representing impaired cerebral perfusion on initial CT angiography (CTA). METHODS: The authors reviewed the treatment results of 148 patients with poor-grade aSAH treated at a single tertiary referral center between 2007 and 2016. Patients with the "venous delay" phenomenon on initial CTA were identified. The outcome assessments used the modified Rankin Scale (mRS) at the 3rd month after aSAH. Factors that may have had an impact on outcome were retrospectively analyzed. RESULTS: Compared with previously identified outcome predictors, the venous delay phenomenon on initial CTA was found to have the strongest correlation with posttreatment outcomes on both univariable (p < 0.0001) and multivariable analysis (OR 4.480, 95% CI 1.565-12.826; p = 0.0052). Older age and a higher Hunt and Hess grade at presentation were other factors that were associated with poor outcome, defined as an mRS score of 3 to 6. CONCLUSIONS: The venous delay phenomenon on initial CTA can serve as an imaging predictor for worse functional outcome and may aid in decision making when treating patients with poor-grade aSAH.

AB - BACKGROUND: Although the current obesity epidemic has been well documented in children and adults, less is known about long-term risks of adult obesity for a given child at his or her present age and weight. We developed a simulation model to estimate the risk of adult obesity at the age of 35 years for the current population of children in the United States. METHODS: We pooled height and weight data from five nationally representative longitudinal studies totaling 176,720 observations from 41,567 children and adults. We simulated growth trajectories across the life course and adjusted for secular trends. We created 1000 virtual populations of 1 million children through the age of 19 years that were representative of the 2016 population of the United States and projected their trajectories in height and weight up to the age of 35 years. Severe obesity was defined as a body-mass index (BMI, the weight in kilograms divided by the square of the height in meters) of 35 or higher in adults and 120% or more of the 95th percentile in children. RESULTS: Given the current level of childhood obesity, the models predicted that a majority of today's children (57.3%; 95% uncertainly interval [UI], 55.2 to 60.0) will be obese at the age of 35 years, and roughly half of the projected prevalence will occur during childhood. Our simulations indicated that the relative risk of adult obesity increased with age and BMI, from 1.17 (95% UI, 1.09 to 1.29) for overweight 2-year-olds to 3.10 (95% UI, 2.43 to 3.65) for 19-year-olds with severe obesity. For children with severe obesity, the chance they will no longer be obese at the age of 35 years fell from 21.0% (95% UI, 7.3 to 47.3) at the age of 2 years to 6.1% (95% UI, 2.1 to 9.9) at the age of 19 years. CONCLUSIONS: On the basis of our simulation models, childhood obesity and overweight will continue to be a major health problem in the United States. Early development of obesity predicted obesity in adulthood, especially for children who were severely obese. (Funded by the JPB Foundation and others.).

PMID- 29171818 TI - Fremanezumab for the Preventive Treatment of Chronic Migraine. AB - BACKGROUND: Fremanezumab, a humanized monoclonal antibody targeting calcitonin gene-related peptide (CGRP), is being investigated as a preventive treatment for migraine. We compared two fremanezumab dose regimens with placebo for the prevention of chronic migraine. METHODS: In this phase 3 trial, we randomly assigned patients with chronic migraine (defined as headache of any duration or severity on >=15 days per month and migraine on >=8 days per month) in a 1:1:1 ratio to receive fremanezumab quarterly (a single dose of 675 mg at baseline and placebo at weeks 4 and 8), fremanezumab monthly (675 mg at baseline and 225 mg at weeks 4 and 8), or matching placebo. Both fremanezumab and placebo were administered by means of subcutaneous injection. The primary end point was the mean change from baseline in the average number of headache days (defined as days in which headache pain lasted >=4 consecutive hours and had a peak severity of at least a moderate level or days in which acute migraine-specific medication [triptans or ergots] was used to treat a headache of any severity or duration) per month during the 12 weeks after the first dose. RESULTS: Of 1130 patients enrolled, 376 were randomly assigned to fremanezumab quarterly, 379 to fremanezumab monthly, and 375 to placebo. The mean number of baseline headache days (as defined above) per month was 13.2, 12.8, and 13.3, respectively. The least-squares mean (+/-SE) reduction in the average number of headache days per month was 4.3+/-0.3 with fremanezumab quarterly, 4.6+/-0.3 with fremanezumab monthly, and 2.5+/-0.3 with placebo (P<0.001 for both comparisons with placebo). The percentage of patients with a reduction of at least 50% in the average number of headache days per month was 38% in the fremanezumab-quarterly group, 41% in the fremanezumab-monthly group, and 18% in the placebo group (P<0.001 for both comparisons with placebo). Abnormalities of hepatic function occurred in 5 patients in each fremanezumab group (1%) and 3 patients in the placebo group (<1%). CONCLUSIONS: Fremanezumab as a preventive treatment for chronic migraine resulted in a lower frequency of headache than placebo in this 12-week trial. Injection-site reactions to the drug were common. The long-term durability and safety of fremanezumab require further study.

AB - BACKGROUND: To assess the effect of a combination strategy for prevention of human immunodeficiency virus (HIV) on the incidence of HIV infection, we analyzed the association between the incidence of HIV and the scale-up of antiretroviral therapy (ART) and medical male circumcision in Rakai, Uganda. Changes in population-level viral-load suppression and sexual behaviors were also examined. METHODS: Between 1999 and 2016, data were collected from 30 communities with the use of 12 surveys in the Rakai Community Cohort Study, an open, population-based cohort of persons 15 to 49 years of age. We assessed trends in the incidence of HIV on the basis of observed seroconversion data, participant-reported use of ART, participant-reported male circumcision, viral-load suppression, and sexual behaviors. RESULTS: In total, 33,937 study participants contributed 103,011 person-visits. A total of 17,870 persons who were initially HIV-negative were followed for 94,427 person-years; among these persons, 931 seroconversions were observed. ART was introduced in 2004, and by 2016, ART coverage was 69% (72% among women vs. 61% among men, P<0.001). HIV viral-load suppression among all HIV positive persons increased from 42% in 2009 to 75% by 2016 (P<0.001). Male circumcision coverage increased from 15% in 1999 to 59% by 2016 (P<0.001). The percentage of adolescents 15 to 19 years of age who reported never having initiated sex (i.e., delayed sexual debut) increased from 30% in 1999 to 55% in 2016 (P<0.001). By 2016, the mean incidence of HIV infection had declined by 42% relative to the period before 2006 (i.e., before the scale-up of the combination strategy for HIV prevention) - from 1.17 cases per 100 person-years to 0.66 cases per 100 person-years (adjusted incidence rate ratio, 0.58; 95% confidence interval [CI], 0.45 to 0.76); declines were greater among men (adjusted incidence rate ratio, 0.46; 95% CI, 0.29 to 0.73) than among women (adjusted incidence rate ratio, 0.68; 95% CI, 0.50 to 0.94). CONCLUSIONS: In this longitudinal study, the incidence of HIV infection declined significantly with the scale-up of a combination strategy for HIV prevention, which provides empirical evidence that interventions for HIV prevention can have a population-level effect. However, additional efforts are needed to overcome disparities according to sex and to achieve greater reductions in the incidence of HIV infection.

AB - BACKGROUND: We tested erenumab, a fully human monoclonal antibody that inhibits the calcitonin gene-related peptide receptor, for the prevention of episodic migraine. METHODS: We randomly assigned patients to receive a subcutaneous injection of either erenumab, at a dose of 70 mg or 140 mg, or placebo monthly for 6 months. The primary end point was the change from baseline to months 4 through 6 in the mean number of migraine days per month. Secondary end points were a 50% or greater reduction in mean migraine days per month, change in the number of days of use of acute migraine-specific medication, and change in scores on the physical-impairment and everyday-activities domains of the Migraine Physical Function Impact Diary (scale transformed to 0 to 100, with higher scores representing greater migraine burden on functioning). RESULTS: A total of 955 patients underwent randomization: 317 were assigned to the 70-mg erenumab group, 319 to the 140-mg erenumab group, and 319 to the placebo group. The mean number of migraine days per month at baseline was 8.3 in the overall population; by months 4 through 6, the number of days was reduced by 3.2 in the 70-mg erenumab group and by 3.7 in the 140-mg erenumab group, as compared with 1.8 days in the placebo group (P<0.001 for each dose vs. placebo). A 50% or greater reduction in the mean number of migraine days per month was achieved for 43.3% of patients in the 70-mg erenumab group and 50.0% of patients in the 140-mg erenumab group, as compared with 26.6% in the placebo group (P<0.001 for each dose vs. placebo), and the number of days of use of acute migraine-specific medication was reduced by 1.1 days in the 70-mg erenumab group and by 1.6 days in the 140-mg erenumab group, as compared with 0.2 days in the placebo group (P<0.001 for each dose vs. placebo). Physical-impairment scores improved by 4.2 and 4.8 points in the 70-mg and 140-mg erenumab groups, respectively, as compared with 2.4 points in the placebo group (P<0.001 for each dose vs. placebo), and everyday-activities scores improved by 5.5 and 5.9 points in the 70-mg and 140-mg erenumab groups, respectively, as compared with 3.3 points in the placebo group (P<0.001 for each dose vs. placebo). The rates of adverse events were similar between erenumab and placebo. CONCLUSIONS: Erenumab administered subcutaneously at a monthly dose of 70 mg or 140 mg significantly reduced migraine frequency, the effects of migraines on daily activities, and the use of acute migraine-specific medication over a period of 6 months. The long-term safety and durability of the effect of erenumab require further study. (Funded by Amgen and Novartis; STRIVE ClinicalTrials.gov number, NCT02456740 .).

AB - The genomic integrity of Mycobacterium tuberculosis is continuously threatened by the harsh survival conditions inside host macrophages, due to immune and antibiotic stresses. Faithful genome maintenance and repair must be accomplished under stress for the bacillus to survive in the host, necessitating a robust DNA repair system. The importance of DNA repair systems in pathogenesis is well established. Previous examination of the M. tuberculosis genome revealed homologues of almost all the major DNA repair systems, i.e. nucleotide excision repair (NER), base excision repair (BER), homologous recombination (HR) and non homologous end joining (NHEJ). However, recent developments in the field have pointed to the presence of novel proteins and pathways in mycobacteria. Homologues of archeal mismatch repair proteins were recently reported in mycobacteria, a pathway previously thought to be absent. RecBCD, the major nuclease-helicase enzymes involved in HR in E. coli, were implicated in the single-strand annealing (SSA) pathway. Novel roles of archeo-eukaryotic primase (AEP) polymerases, previously thought to be exclusive to NHEJ, have been reported in BER. Many new proteins with a probable role in DNA repair have also been discovered. It is now realized that the DNA repair systems in M. tuberculosis are highly evolved and have redundant backup mechanisms to mend the damage. This review is an attempt to summarize our current understanding of the DNA repair systems in M. tuberculosis. PMID- 29171824 TI - Haem-iron plays a key role in the regulation of the Ess/type VII secretion system of Staphylococcus aureus RN6390. AB - The Staphylococcus aureus type VII protein secretion system (T7SS) plays important roles in virulence and intra-species competition. Here we show that the T7SS in strain RN6390 is activated by supplementing the growth medium with haemoglobin, and its cofactor haemin (haem B). Transcript analysis and secretion assays suggest that activation by haemin occurs at a transcriptional and a post translational level. Loss of T7 secretion activity by deletion of essC results in upregulation of genes required for iron acquisition. Taken together these findings suggest that the T7SS plays a role in iron homeostasis in at least some S. aureus strains. PMID- 29171826 TI - Tertiary care centre adherence to unified guidelines for management of periprosthetic joint infections: a gap analysis. AB - BACKGROUND: The success rate of surgical treatment for periprosthetic joint infection (PJI) remains inconsistent in the literature. Variability in PJI clinical guidelines and surgeon adherence to guidelines could affect treatment success. The objectives of this study were to appraise current recommendations for PJI management and develop a unified clinical standard of care, to perform a gap analysis of PJI cases in a tertiary institution to determine the rate of guideline adherence, and to determine if adherence to unified PJI guidelines affected 2-year treatment outcomes. METHODS: We appraised the PJI guidelines from 3 academic medical societies, and consistent statements were aggregated. We retrospectively reviewed all PJI cases in a tertiary care institution. We defined PJI based on Musculoskeletal Infection Society PJI criteria. Surgeon adherence to preoperative, intraoperative, surgical and medical management guidelines was calculated, and we evaluated the association between guideline adherence and 2 year treatment outcomes. RESULTS: The institutional rate of PJI was 1.13% (38 of 3368). Treatment success was 57.8% at 2 years. Unified guideline adherence percentages varied substantially: 92% of patients had preoperative erythrocyte sedimentation rate and C-reactive protein, 97% had intraoperative tissue cultures, 42% had appropriate preoperative arthrocentesis, and 74% underwent guideline-appropriate surgery. Performing appropriate preoperative arthrocentesis significantly correlated with positive treatment outcomes at 2 years (p = 0.028). CONCLUSION: Adherence to PJI guidelines varies considerably, indicating that clinicians are either unaware of them or do not recognize their value for PJI treatment. This study shows the need for institution-based PJI treatment pathways that are consistent with published guidelines and the need to monitor adherence. PMID- 29171827 TI - Comparing the anterior, posterior and lateral approach: gait analysis in total hip arthroplasty. AB - BACKGROUND: The choice of surgical approach for total hip arthroplasty (THA) remains a contentious issue with regards to clinical outcome optimization and restoring patient function. The purpose of this study was to determine the impact of surgical approach for THA on quantitative gait analysis. METHODS: Patients undergoing THA for primary osteoarthritis of the hip were assigned to 1 of 3 surgical approaches: anterior, posterior and lateral. Standardized implants were used at the time of surgery. Three-dimensional gait analysis was performed preoperatively and at 6 and 12 weeks postoperatively. At each time point, we compared temporal parameters, kinematics and kinetics. RESULTS: We included 30 patients in our analysis (10 anterior, 10 posterior, and 10 lateral). The groups were similar with respect to age (p = 0.27), body mass index (p = 0.16), and Charlson Comorbidity Index score (p = 0.66). Temporal parameters were similar among the groups at all time points. The lateral cohort had higher pelvic tilt during stance on the affected leg than the anterior cohort at 6 weeks (p = 0.041). Affected leg ipsilateral trunk lean during stance was higher in the lateral group than in the other cohorts at 6 weeks (p = 0.008) and 12 weeks (p = 0.040). The anterior and posterior groups showed increased external rotation at 6 weeks (p = 0.003) and 12 weeks (p = 0.012) compared with the lateral group. CONCLUSION: Temporal gait parameters were similar following THA for all approaches. Differences in gait kinematics and kinetics exist; however, given the small absolute differences, the clinical importance of these changes remains undetermined. PMID- 29171828 TI - Analysis of postdischarge costs following emergent general surgery in elderly patients. AB - BACKGROUND: As populations age, more elderly patients will undergo surgery. Frailty and complications are considered to increase in-hospital cost in older adults, but little is known on costs following discharge, particularly those borne by the patient. We examined risk factors for increased cost and the type of costs accrued following discharge in elderly surgical patients. METHODS: Acute abdominal surgery patients aged 65 years and older were prospectively enrolled. We assessed baseline clinical characteristics, including Clinical Frailty Scale (CFS) scores. We calculated 6-month cost (in Canadian dollars) from patient reported use following discharge according to the validated Health Resource Utilization Inventory. Primary outcomes were 6-month overall cost and cost for health care services, medical products and lost productive hours. Outcomes were log-transformed and assessed in multivariable generalized linear and zero inflated negative binomial regressions and can be interpreted as adjusted ratios (AR). Complications were assessed according to Clavien-Dindo classification. RESULTS: We included 150 patients (mean age 75.5 +/- 7.6 yr; 54.1% men) in our analysis; 10.8% had major and 43.2% had minor complications postoperatively. The median 6-month overall cost was $496 (interquartile range $140-$1948). Disaggregated by cost type, frailty independently predicted increasing costs of health care services (AR 1.76, 95% confidence interval [CI] 1.43-2.18, p < 0.001) and medical products (AR 1.61, 95% CI 1.15-2.25, p = 0.005), but decreasing costs in lost productive hours (AR 0.39, p = 0.002). Complications did not predict increased cost. CONCLUSION: Frail patients accrued higher health care services and product costs, but lower costs from lost productive hours. Interventions in elderly surgical patients should consider patient-borne cost in older adults and lost productivity in less frail patients. TRIAL REGISTRATION: NCT02233153 (clinicaltrials.gov). PMID- 29171829 TI - Effect of patient decision aid was influenced by presurgical evaluation among patients with osteoarthritis of the knee. AB - BACKGROUND: Decision aids help patients make total joint arthroplasty decisions, but presurgical evaluation might influence the effects of a decision aid. We compared the effects of a decision aid among patients considering total knee arthroplasty at 2 surgical screening clinics with different evaluation processes. METHODS: We performed a subgroup analysis of a randomized controlled trial. Patients were recruited from 2 surgical screening clinics: an academic clinic providing 20-minute physician consultations and a community clinic providing 45 minute physiotherapist/nurse consultations with education. We compared the effects of decision quality, decisional conflict and surgery rate using Cochran Mantel-Haenszel chi2 tests and the Breslow-Day test. RESULTS: We evaluated 242 patients: 123 from the academic clinic (61 who used the decision aid and 62 controls) and 119 from the community clinic (59 who used the decision aid and 60 controls). Results suggested a between-site difference in the effect of the decision aid on the patients' decision quality (p = 0.09): at the academic site, patients who used the decision were more likely to make better-quality decisions than controls (54% v. 35%, p = 0.044), but not at the community site (47% v. 51%, p = 0.71). Fewer patients who used decision aids at the academic site than at the community site experienced decisional conflict (p = 0.007) (33% v. 52%, p = 0.05 at the academic site and 40% v. 24%, p = 0.08 at the community site). The effect of the decision aid on surgery rates did not differ between sites (p = 0.65). CONCLUSION: The decision aid had a greater effect at the academic site than at the community site, which provided longer consultations with more verbal education. Hence, decision aids might be of greater value when more extensive total knee arthroplasty presurgical assessment and counselling are either impractical or unavailable. PMID- 29171830 TI - Process mapping as a framework for performance improvement in emergency general surgery. AB - BACKGROUND: Emergency general surgery conditions are often thought of as being too acute for the development of standardized approaches to quality improvement. However, process mapping, a concept that has been applied extensively in manufacturing quality improvement, is now being used in health care. The objective of this study was to create process maps for small bowel obstruction in an effort to identify potential areas for quality improvement. METHODS: We used the American College of Surgeons Emergency General Surgery Quality Improvement Program pilot database to identify patients who received nonoperative or operative management of small bowel obstruction between March 2015 and March 2016. This database, patient charts and electronic health records were used to create process maps from the time of presentation to discharge. RESULTS: Eighty eight patients with small bowel obstruction (33 operative; 55 nonoperative) were identified. Patients who received surgery had a complication rate of 32%. The processes of care from the time of presentation to the time of follow-up were highly elaborate and variable in terms of duration; however, the sequences of care were found to be consistent. We used data visualization strategies to identify bottlenecks in care, and they showed substantial variability in terms of operating room access. CONCLUSION: Variability in the operative care of small bowel obstruction is high and represents an important improvement opportunity in general surgery. Process mapping can identify common themes, even in acute care, and suggest specific performance improvement measures. PMID- 29171831 TI - Physical performance following acute high-risk abdominal surgery: a prospective cohort study. AB - BACKGROUND: Acute high-risk abdominal (AHA) surgery is associated with high mortality, multiple postoperative complications and prolonged hospital stay. Further development of strategies for enhanced recovery programs following AHA surgery is needed. The aim of this study was to describe physical performance and barriers to independent mobilization among patients who received AHA surgery (postoperative days [POD] 1-7). METHODS: Patients undergoing AHA surgery were consecutively enrolled from a university hospital in Denmark. In the first postoperative week, all patients were evaluated daily with regards to physical performance, using the Cumulated Ambulation Score (CAS; 0-6 points) to assess basic mobility and the activePAL monitor to assess the 24-hour physical activity level. We recorded barriers to independent mobilization. RESULTS: Fifty patients undergoing AHA surgery (mean age 61.4 +/- 17.2 years) were included. Seven patients died within the first postoperative week, and 15 of 43 (35%) patients were still not independently mobilized (CAS < 6) on POD-7, which was associated with pulmonary complications developing (53% v. 14% in those with CAS = 6, p = 0.012). The patients lay or sat for a median of 23.4 hours daily during the first week after AHA surgery, and the main barriers to independent mobilization were fatigue and abdominal pain. CONCLUSION: Patients who receive AHA surgery have very limited physical performance in the first postoperative week. Barriers to independent mobilization are primarily fatigue and abdominal pain. Further studies investigating strategies for early mobilization and barriers to mobilization in the immediate postoperative period after AHA surgery are needed. PMID- 29171832 TI - No. 3 Canadian General Hospital (McGill) in the Great War: service and sacrifice. AB - SUMMARY: During the Great War, McGill University fielded a full general hospital to care for the wounded and sick among the Allied forces fighting in France and Belgium. The unit was designated No. 3 Canadian General Hospital (McGill) and included some of the best medical minds in Canada. Because the unit had a relationship with Sir William Osler, who was a professor at McGill from 1874 to 1885, the unit received special attention throughout the war, and legendary Canadian medical figures, such as John McCrae, Edward Archibald and Francis Scrimger, VC, served on its staff. The unit cared for thousands of victims of the war, and its trauma care advanced through the clinical innovation and research demanded by the nature of its work. Although No. 3 Canadian General Hospital suffered tragedies as well, such as the deaths of John McCrae and Osler's only son Revere, by the war's end the McGill hospital was known as one of the best medical units within the armies in France. PMID- 29171833 TI - Patient-perceived barriers to radiation therapy for breast cancer. AB - SUMMARY: Studies have shown that a number of women do not receive adjuvant radiation therapy following breast-conserving surgery; the reasons have not been well investigated. We reviewed the charts of 267 patients in our institution who did not receive radiation therapy following surgery in order to determine patientstated reasons for nonreceipt. We found that 43% of patients did not receive radiation because they received a completion mastectomy. Excluding these patients, reasons for nonreceipt of radiation therapy were sorted into 9 categories. Most patients declined radiation therapy (against physician advice). We identified 3 major barriers to receipt of radiation therapy: improper patient selection, transportation or ambulatory issues and patient fear surrounding radiation toxicity. All of these reasons are surmountable barriers to radiation receipt.

AB - Intracellular parasitism often results in gene loss, genome reduction, and dependence upon the host for cellular functioning. Rozellomycota is a clade comprising many such parasites and is related to the diverse, highly reduced, animal parasites, Microsporidia. We sequenced the nuclear and mitochondrial genomes of Paramicrosporidium saccamoebae [Rozellomycota], an intranuclear parasite of amoebae. A canonical fungal mitochondrial genome was recovered from P. saccamoebae that encodes genes necessary for the complete oxidative phosphorylation pathway including Complex I, differentiating it from most endoparasites including its sequenced relatives in Rozellomycota and Microsporidia. Comparative analysis revealed that P. saccamoebae shares more gene content with distantly related Fungi than with its closest relatives, suggesting that genome evolution in Rozellomycota and Microsporidia has been affected by repeated and independent gene losses, possibly as a result of variation in parasitic strategies (e.g. host and subcellular localization) or due to multiple transitions to parasitism.

AB - Highly adapted herbivores can phenocopy two-component systems by stabilizing, sequestering and reactivating plant toxins. However, whether these traits protect herbivores against their enemies is poorly understood. We demonstrate that the western corn rootworm Diabrotica virgifera virgifera, the most damaging maize pest on the planet, specifically accumulates the root-derived benzoxazinoid glucosides HDMBOA-Glc and MBOA-Glc. MBOA-Glc is produced by D. virgifera through stabilization of the benzoxazinoid breakdown product MBOA by N-glycosylation. The larvae can hydrolyze HDMBOA-Glc, but not MBOA-Glc, to produce toxic MBOA upon predator attack. Accumulation of benzoxazinoids renders D. virgifera highly resistant to nematodes which inject and feed on entomopathogenic symbiotic bacteria. While HDMBOA-Glc and MBOA reduce the growth and infectivity of both the nematodes and the bacteria, MBOA-Glc repels infective juvenile nematodes. Our results illustrate how herbivores combine stabilized and reactivated plant toxins to defend themselves against a deadly symbiosis between the third and the fourth trophic level enemies. PMID- 29171836 TI - CRIg, a tissue-resident macrophage specific immune checkpoint molecule, promotes immunological tolerance in NOD mice, via a dual role in effector and regulatory T cells. AB - How tissue-resident macrophages (TRM) impact adaptive immune responses remains poorly understood. We report novel mechanisms by which TRMs regulate T cell activities at tissue sites. These mechanisms are mediated by the complement receptor of immunoglobulin family (CRIg). Using animal models for autoimmune type 1 diabetes (T1D), we found that CRIg+ TRMs formed a protective barrier surrounding pancreatic islets. Genetic ablation of CRIg exacerbated islet inflammation and local T cell activation. CRIg exhibited a dual function of attenuating early T cell activation and promoting the differentiation of Foxp3+ regulatory (Treg) cells. More importantly, CRIg stabilized the expression of Foxp3 in Treg cells, by enhancing their responsiveness to interleukin-2. The expression of CRIg in TRMs was postnatally regulated by gut microbial signals and metabolites. Thus, environmental cues instruct TRMs to express CRIg, which functions as an immune checkpoint molecule to regulate adaptive immunity and promote immune tolerance.

AB - The increased survival of treated people living with HIV (PLWH) represents a tremendous accomplishment. However, this has not been accompanied by uniform improvements in quality of life. Many PLWH prematurely develop age-related complications and traditional geriatric syndromes, including frailty. This is a potentially reversible state of vulnerability to adverse outcomes. Its operationalization remains challenging. The most commonly used tools, the frailty phenotype and the frailty index, have their advantages and limitations, but predict similar poor outcomes. Yeoh et al. applied both metrics, and a simpler construct, the Edmonton Frail Scale, to a population of Australian PLWH. Although the prevalence of frailty was generally similar to that in other settings, distinct differences occurred between the tools. This paper adds to the literature on this serious condition in this already vulnerable population. Further research is needed before consensus is reached on how to reliably and simply diagnose frailty in PLWH. PMID- 29171839 TI - Primary pericardial mesothelioma in a 48-year-old patient. PMID- 29171837 TI - Inflammation investigated as a source of pharmacokinetic variability of atazanavir in AIDS Clinical Trials Group protocol A5224s. AB - BACKGROUND: Inflammation is associated with the downregulation of drug metabolizing enzymes and transporters. Thus, we investigated the chronic inflammatory state associated with HIV infection as a source of pharmacokinetic variability of atazanavir. We also explored the association of total bilirubin concentrations with markers of inflammation and endothelial activation. METHODS: Apparent oral clearance (CL/F) of atazanavir was estimated from plasma samples collected from participants in AIDS Clinical Trials Group Study A5202. Several inflammatory and endothelial activation biomarkers were measured at baseline and weeks 24 and 96 as part of metabolic substudy A5224s: high-sensitivity C-reactive protein (hsCRP), interleukin-6, tumour necrosis factor-alpha and its soluble receptors, soluble vascular cellular and intracellular adhesion molecules and total bilirubin. Statistical analysis was performed by a matrix of correlation coefficients between atazanavir CL/F and biomarker concentrations measured at week 24. The correlation between atazanavir clearance and percentage change in bilirubin from baseline to weeks 24 and 96, and between biomarkers and bilirubin concentrations at each week were also evaluated. RESULTS: Among 107 participants, there were no significant correlations observed between atazanavir CL/F and inflammatory and endothelial activation biomarkers measured at week 24 (P>=0.24). As expected, bilirubin increased with increasing exposure to atazanavir (rho= 0.25, P=0.01). Bilirubin concentrations were inversely correlated (P<0.01) with each of the biomarkers except hsCRP. CONCLUSIONS: Atazanavir CL/F did not correlate with the inflammatory biomarkers changes. Inflammatory-mediated inhibition of cytochrome P450 3A may have been attenuated due to atazanavir associated increases of bilirubin, which has known anti-inflammatory properties. PMID- 29171840 TI - What intrinsic and extrinsic factors explain the stoichiometric diversity of aquatic heterotrophic bacteria? AB - The elemental content of microbial communities is dependent upon the physiology of constituent populations, yet ecological stoichiometry has made slow progress toward identifying predictors of how species and strains change the elemental content of their biomass in response to the stoichiometry of elements in resources. We asked whether the elemental content of aquatic bacteria, especially flexibility in elemental content, could be predicted by their phylogeny, maximum growth rate or lake productivity. We examined 137 isolates using chemostats and found that strains differed substantially in how the carbon:nitrogen:phosphorus ratios (C:N:P) in their biomass responded to P-sufficient and P-limiting conditions. The median strain increased its biomass C:N:P from 68:14:1 to 164:25:1 under P limitation. Patterns in elemental content and ratios were partly explained by phylogeny, yet flexibility in elemental content showed no phylogenetic signal. The growth rate hypothesis predicts that P content is positively related to growth rate, but we found weak correlation between maximum growth rate and P content among the strains. Overall, isolates from highly productive lakes had higher maximum growth rates and less flexible biomass N:P than isolates from unproductive lakes. These results show that bacteria present within lake communities exhibit diverse strategies for responding to elemental imbalance. PMID- 29171841 TI - Verification of electronic device technology for measurement and evaluation of thermal exposure of fire fighters and members of rescue teams. AB - BACKGROUND: The work of members of rescue teams could be associated with very high physical and thermal loads. If not timely interrupted, any extreme labour thermal load may lead to a failure of the body and fatal collapse. This risk may be significantly reduced by devices that monitor the response of the body during the intervention and inform rescuers about the need to interrupt the exposure when the critical value of the reference indicator is achieved. The aim of the study was to test the correlation between the data of the newly developed device for signaling the strain of rescuers and the indicators of physiological response of the body. MATERIAL AND METHODS: The tests were performed on 2 physically fit fire fighters dressed in a protective rescue suit and using insulating breathing apparatus, over a wide range of heat load under a model load on a bicycle ergometer in a climatic chamber. RESULTS: The study provided a significant correlation between the body temperature measured in the ear canal and the temperature under the suit sensed by the tested device - the Safety Ambient Monitor (SAM) (R = 0.9007). The temperature under the suit also correlated with the temperature of the chest skin (R = 0.8928) and heart rate (R = 0.8613). CONCLUSIONS: A statistically significant correlation was proven between the temperature sensed by the SAM and the body temperature. The technical solution of sensing the temperature under the suit using the verified SAM technology does not affect or limit fire fighters in their work and minimizes the possibility of damage to the sensor and signaling failures.

AB - BACKGROUND: The main purpose of this article was to examine, whether and to what extend an assessment of work environment and feeling of threat are associated with stress at work performed in health- and life-threatening conditions. Previous studies of the determinants of occupational stress have been carried out in relation to representatives of different occupational groups that are not, however, representatives of one organization. The research was also meant to provide practical guidance for a particular employer. MATERIAL AND METHODS: The study was carried out in the factory of explosives. It involved 95 randomly selected employees of the production departments. Subjective evaluation of work was performed by the examined persons in the Areas of Worklife Survey. It allows to assess the functioning of the employee in the workplace and to recognize the discrepancies between the requirements of the organization and the needs, aspirations and abilities of the examined person. Feeling of insecurity at work was defined by using the Feeling of Danger at Work Survey. The level of stress was assessed using the Perceived Stress Scale (PSS-10). RESULTS: The workload and feeling of danger are relevant to the stress felt by the employees. The workload is also the mediator of the relations between the sense of danger and the stress felt by the examined employees. CONCLUSIONS: At the level of manufacturing process management in an organization, there is a need to reduce the negative impact of physical and mental strain associated with haste and uncertainty.

AB - OBJECTIVES: The objective of the work was to determine the resistance of selected protective clothing and glove materials to permeation of cytostatics such as docetaxel, fluorouracil, and doxorubicin. MATERIAL AND METHODS: The following glove materials were used: natural rubber latex (code A), acrylonitrile-butadiene rubber (code B) and chloroprene rubber (code C). In addition, we tested a layered material composed of a non-woven polyester (PES), a polypropylene (PP) film, and a non-woven PP used for protective coats (code D). The cytostatics were analyzed by liquid chromatography with diode array detection. The tested samples were placed in a purpose-built permeation cell modified to be different from that specified in the standard EN 6529:2001. RESULTS: The tested materials were characterized by good resistance to solutions containing 2 out of the 3 selected cytostatics: doxorubicin and 5-fluorouracil, as indicated by a breakthrough time of over 480 min. Equally high resistance to permeation of the third cytostatic (docetaxel) was exhibited by natural rubber latex, acrylonitrile-butadiene rubber, and chloroprene rubber. However, docetaxel permeated much more readily through the clothing layered material, compromising its barrier properties. CONCLUSIONS: It was found that the presence of additional components in cytostatic preparations accelerated permeation through material samples, thus deteriorating their barrier properties.

AB - To gain an understanding of the transport and thermodynamic behavior of the highly non-ideal mixture methanol + cyclohexane, three complementary approaches, i.e. experiment, molecular simulation and predictive equations, are employed. The temperature and composition dependence of different diffusion coefficients is studied around the miscibility gap at ambient pressure. On the one hand Fick diffusion coefficients are measured experimentally by interferometric probing and on the other hand Maxwell-Stefan diffusion coefficients and intradiffusion coefficients are sampled by equilibrium molecular dynamics simulation at five temperatures below the upper critical temperature of ~319 K. The spinodal curve is determined from extrapolation of the experimental Fick diffusion coefficient data and compared to predictions from excess Gibbs energy models. It is found that these models are not capable to correctly describe the activity coefficients over the whole composition range of the studied mixture. Thus, different parameter sets for a modified Wilson model are used for calculations of the thermodynamic factor, which is needed to transform Maxwell-Stefan into Fick diffusion coefficients and vice versa. Further, predictive equations for the Maxwell-Stefan diffusion coefficient, which are based on intradiffusion coefficients, are compared to simulation results. Using different approaches provides a clearer understanding of the relations between kinetic and thermodynamic properties contributing to the diffusion behavior of partially miscible mixtures. PMID- 29171845 TI - Unusual intramolecular CHO hydrogen bonding interaction between a sterically bulky amide and uranyl oxygen. AB - The selective separation of toxic heavy metals such as uranyl can be accomplished using ligands with stereognostic hydrogen bonding interactions to the uranyl oxo group, as proposed by Raymond and co-workers (T. S. Franczyk, K. R. Czerwinski and K. N. Raymond, J. Am. Chem. Soc., 1992, 114, 8138-8146). Recently, several ligands possessing this weak interaction have been proposed involving the hydrogen bonding of NH and OH based moieties with uranyl oxygen. We herein report the structurally and spectroscopically characterized CHO hydrogen bonding using a sterically bulky amide based ligand. In conjunction with experiments, electronic structure calculations are carried out to understand the structure, binding and the strength of the CHO hydrogen bonding interactions. This weak interaction is mainly due to the steric effect caused by a bulky substituent around the donor group which has direct relevance in designing novel ligands in nuclear waste management processes. Although the kinetics are very slow, the ligand is also highly selective to uranyl in the presence of other interfering ions such as lanthanides. PMID- 29171846 TI - Sm(iii)[12-MCGa(III)shi-4] as a luminescent probe for G-quadruplex structures. AB - G-quadruplexes (GQs), spatial assemblies of guanine-rich DNA strands, play an important role in the regulation of gene expression and chromosome stabilization. These structures are recognized to be useful in cancer therapies as the presence of multiple G-quadruplexes in a telomeric strand stops cancer cell proliferation. Metallacrowns of the type 12-MC-4 form planar structures that have remarkable similarity to G-tetrads in terms of dimension, shape and the ability to bind alkali metal and lanthanide cations in a central cavity. The interaction between the Sm(iii)[12-MCGa(III)shi-4] (SmMC) metallacrown (MC) and human telomeric G quadruplex structures was examined using several methods including CD titrations, CD melting temperatures, fluorescence titration of SmMC with GQ/Na+, fluorescence intercalator displacement (FID) assays and methods measuring the MC quenching effect on the Tb3+/GQ luminescence. It was proven that the studied metallacrown acted as a sensing probe and interacted with quadruplex DNA. The Stern-Volmer quenching constant (Kas) of Tb3+/GQ luminescence was calculated to be 3.9 * 105 M 1. The binding constant using the indirect FID method gave the result of 1.3 * 105 M-1. CD melting temperature experiments reveal the following pattern - the higher the concentration of the complex the lower the registered Tm for quadruplex DNA, which indicates a destabilizing effect of SmMC at higher GQ : MC ratios. These data implicate a shape and size selective interaction between MCs and GQs that may be exploited for telomere detection. PMID- 29171847 TI - A multifunctional Ni(ii) coordination polymer: synthesis, crystal structure and applications as a luminescent sensor, electrochemical probe, and photocatalyst. AB - Herein, a nickel coordination polymer (CP 1), {Ni(1,4-bib)1.5(TPA-Cl2).H2O}n (1,4 bib = 1,4-bis(1H-imidazol-1-yl)benzene, H2TPA-Cl2 = 2,5-dichloro-terephthalic acid), has been synthesized under solvothermal conditions. The structure of CP 1 is a 3D 3-fold interpenetrating framework with the sqc12 topology. The thermal stability and luminescence properties of CP 1 were investigated. Scanning electron microscopy (SEM) images of this material display that it possesses an irregular block 3D structure. Interestingly, CP 1 can serve as a multifunctional material via its luminescence sensing, electrochemical sensing, and photocatalytic properties. The experimental results indicate that CP 1 is an efficient luminescent sensor for the detection of Fe3+ ions in an aqueous solution. In addition, CP 1 exhibits a sensitive and rapid electrochemical response to nitrite ions in water solution. The photocatalytic activities of CP 1 were evaluated in the degradation of different dye contaminants (MB, RhB, and MO), and the results demonstrate that its photocatalytic efficiency for the degradation of MB is highest (92.1% for MB, 85.7% for RhB, and 86.2% for MO). The effects of different dyes, different powers of UV light, and different amounts of catalyst CP 1 on the photocatalytic efficiency were also explored. Finally, the mechanism of the luminescence quenching effect toward Fe3+ ions, electroreduction of nitrite ions, and photocatalytic degradation of different dyes have been investigated in detail. PMID- 29171849 TI - Uracil removal-inhibited ligase reaction in combination with catalytic hairpin assembly for the sensitive and specific detection of uracil-DNA glycosylase activity. AB - Sensitive and specific detection of uracil-DNA glycosylase (UDG) activity is crucial in biomedical study and disease diagnosis. Here, we developed a uracil removal-inhibited ligase reaction in combination with catalytic hairpin assembly (CHA) for the sensitive and specific detection of UDG activity. A hairpin probe is specially designed, which contains two uracil bases in the loop and is extended with toehold and branch-migration domains at the ends of the stem. Two short oligonucleotides are separately hybridized to one-half of the loop of the hairpin probe to form a DNA complex with a nick. Under the action of UDG, two uracil bases in the hairpin-loop are removed to generate apurinic/apyrimidinic (AP) sites. The AP sites locating at the 3'-side of the nick inhibit the ligase reaction, leaving the toehold and branch-migration domains at the ends of the hairpin probe still adjacent. The adjacent toehold and branch-migration domains initiate CHA, producing numerous G-quadruplex (G4) structures, which interact with N-methyl-mesoporphyrin IX (NMM) to generate an enhanced fluorescence signal. The excessive probes would be masked by the ligase reaction that closes the nick and forms a long DNA strand fully complementary to the hairpin domain. The probes then get opened and the toehold/branch-migration domains are not associated, prohibiting the CHA reaction and minimizing false-positive interferences. The detection limit is as low as 0.00028 U mL-1, and UDG can be well distinguished from other DNA glycosylases. Furthermore, this method is successfully applied for detecting UDG activity from HeLa cell lysates. Additionally, the inhibition of UDG activity is analyzed, which shows inhibitor dose-dependent activity suppression. This strategy will provide a promising tool for assaying UDG activity in biomedical study and disease diagnosis. PMID- 29171848 TI - A pilot study on clinical pharmacokinetics and preclinical pharmacodynamics of (+)-epicatechin on cardiometabolic endpoints. AB - We reported that (-)-epicatechin can stimulate mitochondria biogenesis and improve metabolism. However, preliminary studies indicate that the (+) stereoisomer form may be more potent. We evaluated in a preliminary manner, the pharmacokinetics (PK) and initial safety analysis of (+)-epicatechin ((+)-Epi) in healthy and pre-diabetic subjects. Using a mouse model of diet-induced obesity and insulin resistance, we also evaluated the metabolic effects of (+)-Epi vs. (+)-catechin (Cat) to determine class effects. In the Phase I PK study, subjects were provided a single incremental oral dose of (+)-Epi (10, 30 or 100 mg). For the PD study, subjects were provided a single 30 mg dose per day for 7 days. Blood samples were collected and safety measures were performed. Incremental doses of (+)-Epi increase the half-life of blood metabolites from 1.2-4.9 h. The compound was well tolerated and no adverse effects were reported. Seven day dosing of pre-diabetic subjects led to tendencies for reductions in circulating levels of tumor necrosis factor-alpha and monocyte chemoattractant protein-1, which returned to baseline by 7 days after treatment. In animals, 2 weeks of oral dosing (0.003, 0.01, 0.03, 0.1 and 0.3 mg kg-1 day-1) dose dependently improved metabolism-related endpoints (weight gain, glucose, cholesterol, triglyceride, with thresholds as low as 0.01 mg kg-1 day-1). Cat yielded no effects at 0.1 mg kg-1 day-1. Results indicate that (+)-Epi evidences a favorable PK and safety profile. Using a pre-clinical model, the compound positively modulates metabolism, which may link to mitochondrial effects. Effects are not due to general antioxidant actions, as Cat yielded no effects. PMID- 29171850 TI - Intercalative hybridization of layered double hydroxide nanocrystals with mesoporous g-C3N4 for enhancing visible light-induced H2 production efficiency. AB - Efficient visible light active hybrid photocatalysts for H2 production can be synthesized by the intercalative hybridization of Zn-Cr-layered double hydroxide (Zn-Cr-LDH) with a mesoporous g-C3N4 lattice. Small Zn-Cr-LDH nanocrystals with a size of ~6 nm are immobilized in the mesopores of g-C3N4. Beyond an optimal LDH/g C3N4 molar ratio of 0.3, a further increase in the LDH content leads to the surface deposition of LDH crystals on the g-C3N4 material as well as the intercalative immobilization of LDH into its mesopores, indicating the controllability of the LDH deposition site. The Zn-Cr-LDH-g-C3N4 nanohybrids exhibit smaller surface areas than the pristine g-C3N4, confirming the intercalative stabilization of Zn-Cr-LDH nanocrystals in the mesopore of g-C3N4. The hybridization between Zn-Cr-LDH and g-C3N4 is effective in enhancing visible light absorptivity and also in depressing electron-hole recombination, which is attributable to an efficient electronic coupling between both the hybridized components. The present Zn-Cr-LDH-g-C3N4 nanohybrid exhibits promising photocatalytic activities for visible light-induced H2 production at a rate of 155.7 MUmol g-1 h-1, which is much superior to that of the pristine g-C3N4 (21.7 MUmol g-1 h-1). The present study underscores that the intercalative immobilization of Zn-Cr-LDH crystals in the limited space of a mesopore is quite useful in improving the visible light active photocatalyst functionality of mesoporous carbon nitride. PMID- 29171851 TI - A facile and universal strategy for preparation of long wavelength emission carbon dots. AB - Carbon dots (CDs) have emerged as a promising new type of fluorescent nanomaterial, although one of their main problems is the tuning of the emission wavelength toward the long wavelength region. In this work, the influence of reaction solvents to emission of CDs was systematically studied using four groups of classical precursors (citric acid individually mixed with four nitrogenous organic compounds). Water and toluene were selected to represent the hydrophobic and hydrophilic reaction medium, respectively. It is interesting to observe that in toluene solvent, all the CD products yield two emission bands of blue and yellow light, and the relative intensity of the yellow to blue can be finely tuned by the precursors. In contrast, the CDs formed in water only demonstrate blue emission. Systematic studies indicate that the spectral change results from the content control of carbogenic/defect states to surface states and the energy transfer from the carbogenic/defect states to the surface states. Moreover, solid state luminescent CD-polymers were fabricated that also demonstrated continuously tunable emission properties. This work provides a new strategy for recognizing the generation of long wavelength-emitting CDs. PMID- 29171852 TI - Steering on-surface reactions with self-assembly strategy. AB - The control of assembly structures that subsequently help achieve viable functionalities has been one of the key motivations for the exploration of surface molecular assembly. In terms of its functionality and applicability, the assembly is explored as a strategy to steer on-surface reactions primarily by two methods: assembly-assisted and assembly-involved reactions. The functions of the self-assembly strategy are threefold: tweaking reaction selectivities, steering reaction pathways, and directing reaction sites. The governing principle herein is that the assembly strategy can apply a surface confinement effect that affects the energy barrier and pre-exponential factor of the Arrhenius equation for the dynamics of the target reaction. Development of such a strategy may reveal new routes to steer on-surface reactions and even single molecule properties in surface chemistry. PMID- 29171853 TI - Lamellar zirconium phosphates to host metals for catalytic purposes. AB - In the present study a porous lamellar zirconium phosphate heterostructure (PPH) formed from zirconium(iv) phosphate expanded with silica galleries (P/Zr molar ratio equal to 2 and (Si + Zr)/P equal to 3) was prepared to host noble metals. Textural and structural characterization of PPH-noble metal materials was carried out in order to elucidate the location and dispersion of the metallic particles and the properties of the resulting material to be used in catalytic processes. In the present paper, their activity in the catalytic hydrodeoxygenation (HDO) reaction of dibenzofuran (DBF) was evaluated. X-ray diffraction (XRD), solid state nuclear magnetic resonance (NMR) and X-ray photoelectron spectroscopy (XPS) evidenced that the structure of the pillared zirconium phosphate material was not modified by the incorporation of Pt and Pd. Moreover, transmission electron microscopy (TEM) showed a different dispersion of the noble metal. The acidity of the resulting PPH-noble metal materials also changed, although in all cases the acidity was of weak nature, and the incorporation of noble metals affected Bronsted acid sites as observed from 31P NMR spectra. In general, the textural, structural and acidic properties of the resulting materials suggest that PPH can be considered a good candidate to be used as a catalytic support. Thus, the catalytic results of the PPH-noble metal samples indicated that the Pd sample showed a stable behavior probably ascribed to a high dispersion of the active phase. However, the Pt sample suffered from fast deactivation. The selectivity to the reaction products was strongly dependent on the noble metal employed. PMID- 29171854 TI - Preparation and characterization of terdentate [C,N,N] acetophenone and acetylpyridine hydrazone platinacycles: a DFT insight into the reaction mechanism. AB - The reaction of N-ortho-chlorophenyl-substituted acetylpyridine hydrazones (a and d) with K2[PtCl4] (n-butanol/water, 100 degrees C) gave mononuclear complexes 1a and 1d with the ligands as [N,N] bidentate. In contrast, the reaction of N-phenyl or N-meta-chlorophenyl hydrazones (b and c, respectively) under analogous reaction conditions gave the cycloplatinated species 2b and 2c with the ligand as [C,N,N] terdentate. The treatment of the mononuclear complexes 1a and 1d with NaOAc (n-butanol, 100 degrees C) gave the corresponding cycloplatinated complexes 2a and 2d. Acetophenone hydrazone platinacycle 2e was prepared in a similar fashion and its reaction with tertiary mono- and triphosphines gave mono- or trinuclear species depending on the reaction conditions. The X-ray crystal structures of some of these complexes showed interesting pi-pi slipped stacking interactions between metallacyclic rings which, according to NCI analyses, showed an aromatic character. With an aim to rationalize the different reactivities shown by acetylpyridine hydrazones and the precise role of the acetate anion, the energy profiles for the three main steps of cycloplatination (iminoplatinum complex formation, chelation and cyclometallation) have been determined by using the DFT (M06) methods. Calculations indicate that the cycloplatination of 1b proceeds via electrophilic substitution, involving the direct replacement of the chloride anion at the Pt(ii) centre with the N-phenyl moiety as the rate determining step, to give an agostic intermediate 5b+ that, subsequently, leads to the elimination of a proton as hydrogen chloride. When present as an "external" base, acetate enters the coordination sphere around the Pt(ii) centre and facilitates hydrazone N-H deprotonation and electrophilic C-H activation through a dissociative route, leading to a Wheland-type sigma-complex intermediate 9ac. PMID- 29171855 TI - A gel aging effect in the synthesis of open-framework gallium phosphates: structure solution and solid-state NMR of a large-pore, open-framework material. AB - The templated zeolite-analogue GaPO-34 (CHA structure type) crystallises from a gel precursor Ga2O3 : 2H3PO4 : 1HF : 1.7SDA : 70H2O (where SDA = structure directing agent), treated hydrothermally for 24 hours at 170 degrees C using either pyridine or 1-methylimizadole as SDA and one of either poorly crystalline epsilon-Ga2O3 or gamma-Ga2O3 as gallium precursor. If the same gels are stirred for periods shorter than 2 hours but treated under identical hydrothermal conditions, then a second phase crystallises, free of GaPO-34. If beta-Ga2O3 is used as a reagent only the second phase is found to crystallise, irrespective of gel aging time. The competing phase, which we denote GaPO-34A, has been structurally characterised using synchrotron powder X-ray diffraction for the pyridine material, GaPO-34A(pyr), and using single-crystal X-ray diffraction for the 1-methylimiazole material, GaPO-34A(mim). The structure of GaPO-34A(pyr), P1[combining macron], a = 10.22682(6) A, b = 12.09585(7) A, c = 13.86713(8) A, alpha = 104.6531(4) degrees , beta = 100.8111(6) degrees , gamma = 102.5228(6) degrees , contains 7 unique gallium sites and 6 phosphorus sites, with empirical formula [Ga7P6O24(OH)2F3(H2O)2].2(C5NH6). GaPO-34A(mim) is isostructural but is modelled as a half volume unit cell, P1[combining macron], a = 5.0991(2) A, b = 12.0631(6) A, c = 13.8405(9) A, alpha = 104.626(5) degrees , beta = 100.346(5) degrees , gamma = 101.936(4) degrees , with a gallium and a bridging fluoride partially occupied and two partially occupied SDA sites. Solid-state 31P and 71Ga NMR spectroscopy confirms the structural complexity of GaPO-34A with signals resulting from overlapping lineshapes from multiple Ga and P sites, while 1H and 13C solid-state NMR spectra confirm the presence of the protonated SDA and provide evidence for disorder in the SDA. The protonated SDA is located in 14 ring one-dimensional channels with hydrogen bonding deduced from the SDA nitrogens to framework oxygen distances. Upon thermal treatment to investigate SDA removal, structure collapse occurs, which may be due the large number of bridging hydroxides and fluorides in the as-made material, and the unequal amounts of gallium and phosphorus present. PMID- 29171856 TI - 2-Acyl-1,1,3,3-tetracyanopropenides (ATCN): structure characterization and luminescence properties of ammonia and alkali metal ATCN salts. AB - Herein, syntheses, crystal structures, and photoluminescence properties of 24 new ammonia and alkali metal ATCN salts characterized via single-crystal X-ray diffraction are reported. Moreover, ten structure types of these salts have been described, three of which are predominant. Some ATCNs were obtained as two crystalline polymorphs. It was estimated that most ATCN powders exhibited yellow green fluorescence (at 450-600 nm). For samples that possess fluorescence of low intensity in the solid state, several optical centers of emission exist. It was speculated that the obtained spectral features were due to anion-anion intermolecular interactions. ATCN being a new representative of stable tetracyanoallyl salts is a promising candidate for creation of various 1D, 2D, and 3D supramolecular structures and potential functional materials.

PMID- 29171858 TI - Advances in single quantum dot-based nanosensors. AB - Single-molecule detection provides a simple and ultrasensitive platform to quantify target molecules by simply counting the individual fluorescence signals. Quantum dots (QDs) are novel semiconductor nanocrystals with distinct characteristics of high brightness, large Stokes shift and broad absorption spectra, high molar extinction coefficients, high quantum yield, good photostability and long fluorescence lifetime. The combination of single-molecule detection with QDs enables the development of single QD-based nanosensors with extremely high sensitivity. Single QD-based nanosensors may be divided into two categories based on single QD burst coincidence detection and single QD fluorescence resonance energy transfer (FRET) detection, and have significant advantages of high signal-to-noise ratio, high sensitivity, rapidity, and low sample consumption. The single QD-based nanosensors have the capability of directly detecting low-abundance species without the need for nucleic acid amplification, and may elucidate a variety of biological and biochemical phenomena in real time using single QD tracking. In this review, we summarize the recent advances in single QD-based nanosensors and their applications for sensitive detection of DNAs, microRNAs, proteins, enzymes, small molecules and viruses. We highlight the challenges and future direction of single QD-based nanosensors as well.

AB - BACKGROUND: Treatments for the disinfection of irrigation water have to be evaluated by demonstration tests carried out under commercial settings taking into account not only their antimicrobial activity but also the potential phytotoxic effects on the crop. The consequences of the treatment of irrigation water with chlorine dioxide (ClO2 ) used for sprinkler irrigation of baby spinach in two commercial agricultural fields was assessed. RESULTS: Residual ClO2 levels at the sprinklers in the treated field were always below 1 mg L-1 . ClO2 treatment provoked limited but statistically significant reductions in culturable Escherichia coli counts (0.2-0.3 log reductions), but not in the viable E. coli counts in water, suggesting the presence of viable but non-culturable cells (VBNC). Although disinfected irrigation water did not have an impact on the microbial loads of Enterobacteriaceae nor on the quality characteristics of baby spinach, it caused the accumulation of chlorates (up to 0.99 mg kg-1 in plants) and the reduction of the photosynthetic efficiency of baby spinach. CONCLUSION: Low concentrations of ClO2 are effective in reducing the culturable E. coli present in irrigation water but it might induce the VBNC state. Presence of disinfection by-products and their accumulation in the crop must be considered to adjust doses in order to avoid crop damage and chemical safety risks.

PMID- 29171861 TI - Matching-adjusted indirect comparison of efficacy in patients with moderate-to severe plaque psoriasis treated with ixekizumab vs. secukinumab. AB - BACKGROUND: Head-to-head randomized studies comparing ixekizumab and secukinumab in the treatment of psoriasis are not available. OBJECTIVES: To assess efficacy and quality of life using matching-adjusted indirect comparisons for treatment with ixekizumab vs. secukinumab. METHODS: Psoriasis Area and Severity Index (PASI) improvement of at least 75%, 90% and 100% and Dermatology Life Quality Index (DLQI) 0/1 response rates for approved dosages of ixekizumab (160 mg at Week 0, then 80 mg every two weeks for the first 12 weeks) and secukinumab (300 mg at Weeks 0, 1, 2, 3 and 4, then 300 mg every 4 weeks) treatment were compared using data from active (etanercept and ustekinumab) and placebo-controlled studies. Comparisons were made using the Bucher (BU) method and two modified versions of the Signorovitch (SG) method (SG total and SG separate). Subsequently, results based on active treatment common comparators were combined using generic inverse-variance meta-analysis. RESULTS: In the meta-analysis of studies with active comparators, PASI 90 response rates were 12.7% [95% confidence interval (CI) 5.5-19.8, P = 0.0005], 10.0% (95% CI 2.1-18.0, P = 0.01) and 11.2% (95% CI 3.2-19.1, P = 0.006) higher and PASI 100 response rates were 11.7% (95% CI 5.9-17.5, P < 0.001), 12.7% (95% CI 6.0-19.4, P < 0.001) and 13.1% (95% CI 6.3-19.9, P < 0.001) higher for ixekizumab compared with secukinumab using BU, SG total and SG separate methods. PASI 75 results were comparable when SG methods were used and favoured ixekizumab when the BU method was used. Week 12 DLQI 0/1 response rates did not differ significantly. CONCLUSIONS: Ixekizumab had higher PASI 90 and PASI 100 responses at week 12 compared with secukinumab using adjusted indirect comparisons. PMID- 29171862 TI - Deployment-Related Military Sexual Trauma Predicts Heavy Drinking and Alcohol Problems Among Male Reserve and National Guard Soldiers. AB - BACKGROUND: Military sexual trauma (MST) is associated with a range of deleterious mental and physical health consequences; however, far less attention has been paid to the associations between MST and negative health behaviors, such as substance abuse. This study examined 2 focal research questions: (i) What is the prevalence of experiencing MST during deployment among male Reserve and National Guard soldiers? and (ii) to what extent is the degree of MST exposure during deployment associated with frequent heavy drinking and alcohol problems postdeployment? METHODS: Data from male soldiers who had been deployed (N = 248) were drawn from the baseline wave of Operation: SAFETY (Soldiers And Families Excelling Through the Years) an ongoing study examining health among U.S. Army Reserve and National Guard and their partners. Participants were recruited over a 15-month period (Summer 2014 to Fall 2015) from units in New York State. Deployments occurred prior to the baseline wave of the study. Analyses examined the relation between degree of MST exposure during soldiers' most recent deployment and (i) frequent heavy drinking and (ii) alcohol problems, measured at baseline, controlling for posttraumatic stress disorder symptoms and age. RESULTS: 17.3% of the male service members reported experiencing MST during their most recent deployment. Further, greater MST exposure was associated with a greater likelihood of engaging in frequent heavy drinking (adjusted risk ratio [aRR] = 1.03, 95% CI [1.01, 1.05]) and experiencing alcohol problems (aRR = 1.03, 95% CI [1.01, 1.06]) at baseline. CONCLUSIONS: Findings demonstrate that MST rates are high among male Reserve and National Guard soldiers, and greater MST exposure is associated with an increased likelihood of engaging in frequent heavy drinking and experiencing alcohol problems among a population already at risk for problematic alcohol use.

PMID- 29171863 TI - Schistosoma mansoni-specific immune responses and allergy in Uganda. AB - Low allergy-related disease (ARD) prevalence in low-income countries may be partly attributed to helminth infections. In the Schistosoma mansoni (Sm)-endemic Lake Victoria islands (Uganda), we recently observed positive helminth-allergy associations, despite low ARD prevalence. To understand how Sm-induced cytokine and antibody profiles might influence allergic response profiles in this population, we assessed Schistosoma worm (SWA)- and egg antigen (SEA)-specific Th1 (IFN-gamma), Th2 (IL-5, IL-13) and regulatory (IL-10) cytokine profiles (n = 407), and total (n = 471), SWA-, SEA- and allergen (house dust mite [HDM] and cockroach)-specific (as)IgE and IgG4 profiles (n = 2117) by ELISA. Wheeze was inversely associated with SWA-specific IFN-gamma (P < .001) and IL-10 (P = .058), and SEA-specific IL-5 (P = .004). Conversely, having a detectable asIgE response was positively associated with SWA-specific IL-5 (P = .006) and IL-10 (P < .001). Total, SWA-, SEA- and allergen-specific IgE and IgG4 responses were higher among Sm Kato-Katz positive (SmKK+) and skin prick test (SPT)+ individuals compared to SmKK- and SPT- individuals. However, total and asIgG4/IgE ratios were lower among SPT+ and wheezing individuals. We conclude that, in this population, helminth induced antibody and cytokine responses may underlie individual positive helminth atopy associations, while the overall IgG4-IgE balance may contribute to the low overall prevalence of clinical allergies in such settings.

PMID- 29171867 TI - Enthusiastic portrayal of 3D bioprinting in the media: Ethical side effects. AB - There has been a surge in mass media reports extolling the potential for using three-dimensional printing of biomaterials (3D bioprinting) to treat a wide range of clinical conditions. Given that mass media is recognized as one of the most important sources of health and medical information for the general public, especially prospective patients, we report and discuss the ethical consequences of coverage of 3D bioprinting in the media. First, we illustrate how positive mass media narratives of a similar biofabricated technology, namely the Macchiarini scaffold tracheas, which was involved in lethal experimental human trials, influenced potential patient perceptions. Second, we report and analyze the positively biased and enthusiastic portrayal of 3D bioprinting in mass media. Third, we examine the lack of regulation and absence of discussion about risks associated with bioprinting technology. Fourth, we explore how media misunderstanding is dangerously misleading the narrative about the technology. PMID- 29171868 TI - Efficient quantification of water content in edible oils by headspace gas chromatography with vapour phase calibration. AB - BACKGROUND: An automated and accurate headspace gas chromatographic (HS-GC) technique was investigated for rapidly quantifying water content in edible oils. In this method, multiple headspace extraction (MHE) procedures were used to analyse the integrated water content from the edible oil sample. A simple vapour phase calibration technique with an external vapour standard was used to calibrate both the water content in the gas phase and the total weight of water in edible oil sample. After that the water in edible oils can be quantified. RESULTS: The data showed that the relative standard deviation of the present HS GC method in the precision test was less than 1.13%, the relative differences between the new method and a reference method (i.e. the oven-drying method) were no more than 1.62%. CONCLUSION: The present HS-GC method is automated, accurate, efficient, and can be a reliable tool for quantifying water content in edible oil related products and research.

AB - BACKGROUND: Irrigation water disinfection reduces the microbial load but it might lead to the formation and accumulation of disinfection by-products (DBPs) in the crop. If DBPs are present in the irrigation water, they can accumulate in the crop, particularly after the regrowth, and be affected by the postharvest handling such as washing and storage. To evaluate the potential accumulation of DBPs, baby lettuce was grown using irrigation water treated with electrolysed water (EW) in a commercial greenhouse over three consecutive harvests and regrowths. The impact of postharvest practices such as washing and storage on DBP content was also assessed. RESULTS: Use of EW caused the accumulation of chlorates in irrigation water (0.02-0.14 mg L-1 ), and in the fresh produce (0.05 0.10 mg kg-1 ). On the other hand, the disinfection treatment had minor impact regarding the presence of trihalomethanes (THMs) in water (0.3-8.7 MUg L-1 max), and in baby lettuce (0.3-2.9 MUg kg-1 max). CONCLUSIONS: Disinfection of irrigation water with EW caused the accumulation of chlorates in the crop reaching levels higher than the current maximum residual limit established in the EU legislation for leafy greens.

AB - Respiratory supercomplex factor (Rcf) 1 is a membrane-bound protein that modulates the activity of cytochrome c oxidase (CytcO) in Saccharomyces cerevisiae mitochondria. To investigate this regulatory mechanism, we studied the interactions of CytcO with potassium cyanide (KCN) upon removal of Rcf1. While the addition of KCN to the wild-type mitochondria results in a full reduction of heme a, with the rcf1Delta mitochondria, a significant fraction remains oxidized. Upon addition of ascorbate in the presence of O2 and KCN, the reduction level of hemes a and b was a factor of ~ 2 larger with the wild-type than with the rcf1Delta mitochondria. These data indicate that turnover of CytcO was less blocked in rcf1Delta than in the wild-type mitochondria, suggesting that Rcf1 modulates the structure of the catalytic site. PMID- 29171872 TI - Topological characterization of the mitochondrial phospholipid scramblase 3. AB - Scramblases redistribute phospholipids in biological membranes. Phospholipid scramblase 3 (PLSCR3), which is located in mitochondria, has been reported to be involved in cardiolipin distribution from the inner to the outer membrane, thus regulating cellular processes such as apoptosis or mitophagy. However, the localization and topology of this protein has not been convincingly addressed to support a role in intermembrane phospholipid transfer. Here, we studied PLSCR3 topology within mitochondria. We show that PLSCR3 inserts in the inner membrane (IM) via its C-terminal transmembrane helix, whereas its N-terminal portion is oriented toward the intermembrane space where it is activated by calcium. Our results suggest that PLSCR3, via its C-terminal transmembrane domain, participates in the bidirectional movement of phospholipids within the IM. PMID- 29171871 TI - Cytokine responses, microbial aetiology and short-term outcome in community acquired pneumonia. AB - BACKGROUND: The inflammatory response to community-acquired pneumonia (CAP) is orchestrated through activation of cytokine networks and the complement system. We examined the association of multiple cytokines and the terminal complement complex (TCC) with microbial aetiology, disease severity and short-term outcome. MATERIALS AND METHODS: Plasma levels of 27 cytokines and TCC were analysed in blood samples obtained at hospital admission, clinical stabilization and 6-week follow-up from 247 hospitalized adults with CAP. Fourteen mediators were included in final analyses. Adverse short-term outcome was defined as intensive care unit (ICU) admission and 30-day mortality. RESULTS: Cytokine and TCC levels were dynamic in the clinical course of CAP, with highest levels seen at admission for most mediators. Admission levels of cytokines and TCC did not differ between groups of microbial aetiology. High admission levels of IL-6 (odds ratio [OR] 1.47, 95% confidence interval [CI] 1.18-1.84, P = .001), IL-8 (OR 1.79, 95% CI 1.26-2.55, P = .001) and MIP-1beta (OR 2.28, 95% CI 1.36-3.81, P = .002) were associated with a CURB-65 severity score of >=3, while IL-6 (OR 1.37, 95% CI 1.07 1.74, P = .011) and MIP-1beta (OR 1.86, 95% CI 1.03-3.36, P = .040) were associated with a high risk of an adverse short-term outcome. CONCLUSIONS: In this CAP cohort, admission levels of IL-6, IL-8 and MIP-1beta were associated with disease severity and/or adverse short-term outcome. Still, for most mediators, only nonsignificant variations in inflammatory responses were observed for groups of microbial aetiology, disease severity and short-term outcome. PMID- 29171873 TI - Let it go: Relationship autonomy predicts pro-relationship responses to partner transgressions. AB - OBJECTIVE: The purpose of the present research is to better understand how relationship autonomy-having more self-determined reasons for being committed to a relationship-contributes to pro-relationship responses to transgressions in romantic relationships (e.g., forgiveness and accommodation). METHOD: Study 1 employed a cross-sectional design (N = 350) and Study 2 used a weekly diary (N = 121) to test associations between relationship autonomy and pro-relationship responses to transgressions. Studies 3 and 4 utilized dyadic designs (Study 3: N = 200 couples, 400 individuals; Study 4: N = 275 couples, 550 individuals) to determine how both partners' relationship autonomy is associated with pro relationship responses. RESULTS: Results revealed that relationship autonomy is robustly associated with pro-relationship responses to transgressions, both as general tendencies and as responses to idiosyncratic transgressions. Results of actor-partner interdependence model (APIM) analyses in Studies 3 and 4 provide evidence that one's partner's relationship autonomy is important for promoting pro-relationship responses as well. Study 4 also found that people perceive that partners respond better to transgressions if their partner is high in relationship autonomy. CONCLUSIONS: This research provides consistent and compelling evidence that the degree of self-determination underlying commitment is important for understanding how people respond to transgressions in their relationships, beyond their current levels of commitment. PMID- 29171874 TI - Serum paraoxonase-1 activity is inversely related to free thyroxine in euthyroid subjects: The PREVEND Cohort Study. AB - BACKGROUND: Low-normal thyroid function within the euthyroid range has been suggested to enhance atherosclerosis susceptibility. Paraoxonase-1 (PON-1) may protect against atherosclerotic cardiovascular disease development by attenuating oxidative stress. We evaluated relationships of PON-1 with thyroid stimulating hormone (TSH), free T4 , free T3 , lipids and apolipoprotein (apo)A-I in euthyroid subjects, and assessed whether such relationships are modified in the context of the metabolic syndrome (MetS). MATERIALS AND METHODS: Serum PON-1 activity (arylesterase activity), TSH, free T4 , free T3 , lipids and apoA-I was measured in 2206 euthyroid subjects (aged 28-75 years; 1138 men (age 49 +/- 13 years) and 1068 women (age 46 +/- 12 years), recruited from the general population (PREVEND cohort). RESULTS: In age- and sex-adjusted analysis, PON-1 activity (divided into tertiles) was positively related to TSH (beta = -0.045, P = .036) and inversely to free T4 (beta = -0.042, P = .050) but not to free T3 (beta = -0.027, P = .20). PON-1 activity was positively related to total cholesterol, non-HDL cholesterol and triglycerides, as well as to HDL cholesterol and apoA-I (P < .01 to <.001). The inverse relationship of PON-1 activity with free T4 remained present after adjustment for lipids and other potential confounders (beta = -0.066, P = .002), but the positive relationship with TSH lost significance (beta = 0.034, P = .11). The inverse relationship of PON-1 activity with free T4 was not different in subjects with vs without MetS (P = .94), nor modified by the presence of its individual components (P >= .22 for each). CONCLUSIONS: Serum PON-1 activity is inversely associated with free T4 in euthyroid subjects, suggesting that low-normal thyroid function may affect PON-1 regulation. PMID- 29171875 TI - Transcriptomic analysis on responses of the liver and kidney of finishing pigs fed cadmium contaminated rice. AB - BACKGROUND: Cadmium (Cd) is a common harmful substance that has many deleterious effects on the liver and kidney. Most reports about Cd toxic studies focused on its inorganic status, whereas the toxicity of Cd in organic materials is less studied. Here, we performed RNA-seq to explore the influences of Cd contaminated rice on function of the liver and kidney of finishing pigs. RESULTS: The concentration of Cd in liver and kidney of pigs fed Cd contaminated rice increased by 4.00 and 2.94 times, respectively, compared to those in the control group. With transcriptomic analysis, approximately 4-6 * 107 clean reads were acquired. Five differently expressed genes (DEGs) were identified in the liver, and 12 DEGs in the kidney. SPHK2 was commonly down-regulated. No significantly enriched gene ontology (GO) terms were identified. By Kyoto encyclopaedia of genes and genomes (KEGG) enrichments, four pathways were identified in hepatic tissue, and five pathways in nephritic tissue. Intriguingly, two pathways (sphingolipid metabolism and VEGF signalling pathway) were altered both in the liver and kidney. CONCLUSION: Cd contaminated rice may cause liver and kidney damage and inflammation, or even lead to more severe harm to these tissues. (c) 2017 Society of Chemical Industry. PMID- 29171876 TI - Decreased platelet inhibition by P2Y12 receptor blockers in anaemia. AB - BACKGROUND: Anaemic patients undergoing angioplasty and stenting are at an increased risk of ischaemic events, which may be caused by an inadequate response to antiplatelet therapy with adenosine diphosphate (ADP) P2Y12 inhibitors. In the current study, we investigated the associations between anaemia and on-treatment platelet reactivity in clopidogrel-treated (group 1, n = 306) and prasugrel /ticagrelor-treated (group 2, n = 109) patients undergoing elective and acute angioplasty with stent implantation, respectively. MATERIALS AND METHODS: Monocyte-platelet aggregate (MPA) formation was determined by flow cytometry in both groups. On-treatment residual platelet reactivity in response to ADP was assessed by light transmission aggregometry (LTA) in both groups, and by the VerifyNow P2Y12 assay and the Impact-R in group 1. P-selectin expression was measured by flow cytometry in group 2. RESULTS: In both groups, anaemia was associated with significantly higher MPA formation in response to ADP (both P <= .02). Moreover, by LTA maximal aggregation in response to ADP was significantly higher in patients with anaemia in both groups (both P < .05), and anaemic patients in group 1 had a significantly higher on-treatment platelet reactivity by the VerifyNow P2Y12 assay and the Impact-R than those without anaemia (both P < .001). In group 2, significantly higher platelet surface expression of P selectin was seen in anaemia after stimulation with ADP (P = .02). CONCLUSION: Anaemia is associated with decreased platelet inhibition by ADP P2Y12 receptor antagonists after elective and acute percutaneous interventions with stent implantation. However, due to inconsistencies between different platelet function tests additional data are needed to clarify the role of anaemia for platelet inhibition. PMID- 29171877 TI - Personality traits and maladaptivity: Unipolarity versus bipolarity. AB - OBJECTIVE: Dimensional personality trait models have gained favor as an alternative to categorical personality disorder (PD) diagnosis; however, debate persists regarding whether these traits should be conceptualized as maladaptive at both extremes (i.e., maladaptively bipolar) or just one trait pole (i.e., unipolar). METHOD: To inform the debate on maladaptive bipolarity, linear and nonlinear relations between personality traits and dysfunction were examined in a large psychiatric patient sample (N = 365). Participants self-reported on normal range and pathological personality domains, life satisfaction, specific interpersonal problems, and broad psychosocial functioning. In addition, participants were interviewed regarding specific psychiatric symptoms and broad psychosocial functioning. RESULTS: All traits related moderately to strongly with at least one dysfunction variable. All traits were predominantly correlated with dysfunction at one pole; however, several small linear relations provided some evidence for maladaptively high Extraversion and Agreeableness. None of the significant nonlinear effects provided clear evidence for maladaptivity at both ends of any trait. CONCLUSIONS: Taken together, these results suggest that broad personality traits are predominantly maladaptive at one extreme; however, in limited cases, the opposite extreme may also be maladaptive. PMID- 29171878 TI - Tophus size is associated with hallux valgus deformity in gout. AB - OBJECTIVE: Hallux valgus (HV) and gout are common pathologies of the first metatarsophalangeal joint (MTP1) leading to pain and deformation. In this study, we aimed to determine the correlation between tophus size and characteristics of HV in gouty patients. METHODS: In this case-control study, we included patients with gout (the presence of monosodium urate crystals in synovial fluid) and control patients with spondyloarthritis, without crystal disease disorders. Radiographic assessment and ultrasound (US) assessment were performed by two blinded operators. US features of gout (double contour [DC] sign and/or tophus) were collected. HV was defined by hallux abductus (HA) angle >=20 degrees and/or intermetatarsal angle (IM) >=10 degrees . Correlation between US findings and HV angles was estimated by Spearman correlation coefficient. RESULTS: We included 56 gouty patients (87.5% males, mean age of 63.9 +/- 12.2 years) and 41 control patients (90% males, mean age of 59.0 +/- 12.8 years). HV was more frequent in patients with gout than controls (62% vs 37%, P = .0007). Regardless of HV status, correlations were found between the size of US tophi and IM (r = .3381, P = .003) and HA angles (r = .2344, P = .043). CONCLUSIONS: Our results confirm a high prevalence of HV in gouty patients. We also observed a correlation between the size of the US tophus and the angles defining HV, which suggests a link between urate deposition load and HV. Early urate-lowering therapy for gout could limit the occurrence of HV. PMID- 29171879 TI - Bidirectional associations between emotions and school adjustment. AB - OBJECTIVE: We examined the relations of children's (N = 301) observed expression of negative and positive emotion in classes or nonclassroom school contexts (i.e., lunch and recess) to school adjustment from kindergarten to first grade. METHOD: Naturalistic observations of children's emotional expressivity were collected, as were teachers' reports of children's school engagement and relationship quality with teachers and peers. RESULTS: In longitudinal panel models, greater teacher-student conflict and lower student engagement in kindergarten predicted greater negative expressivity in both school contexts. School engagement and peer acceptance in kindergarten positively predicted first grade positive emotion in the classroom. Suggestive of possible bidirectional relations, there was also small unique prediction (near significant) from negative expressivity at lunch and recess to higher teacher-student conflict, from negative expressivity in the classroom to low peer acceptance, and from positive expressivity in the classroom to higher peer acceptance. CONCLUSIONS: The pattern of findings suggests that the quality of experience at school uniquely predicts children's emotional expressivity at school more consistently than vice versa-a finding that highlights the important role of school context in young children's emotionality at school. PMID- 29171880 TI - Torsional fatigue resistance of pathfinding instruments manufactured from several nickel-titanium alloys. AB - AIM: To evaluate the torsional properties of pathfinding nickel-titanium (NiTi) rotary instruments manufactured from several NiTi alloys, ProGlider (M-wire), Hyflex GPF (conventional NiTi Wire and controlled memory wire), Logic (conventional NiTi wire and controlled memory wire) and Mtwo (conventional NiTi wire). METHODOLOGY: A total of 56 NiTi instruments from Glidepath rotary systems (n = 8) were used: Logic (size 25, .01 taper), Logic CM (size 25, .01 taper), ProGlider (size 16, .02 taper), Hyflex GPF (size 15, .01 taper), Hyflex GPF CM (size 15, .02 taper; size 20, .02 taper) and Mtwo (size 10, .04 taper). The torsion tests were performed based on ISO 3630-1 (1992). Three millimetres of each instrument tip was clamped to a small load cell by a lever arm linked to the torsion axis. Data were analysed using a one-way analysis of variance (anova) and Tukey test with a significance level at a = 5%. RESULTS: The Logic size 25, .01 taper had significantly higher torsional strength values (P < 0.05). The ProGlider was significantly different when compared with Hyflex GPF size 15, .01 taper and size 15, .02 taper (P < 0.05). The Logic CM size 25, .01 taper had significantly higher torsional strength than Hyflex GPF size 15, .01 taper and size 15, .02 taper (P < 0.05). No difference was found amongst Mtwo size 10, .04 taper and Hyflex GPF groups (size 15, .01 taper; size 15, .02 taper; size 20, .02 taper). In relation to the angle of rotation, Logic CM size 25, .01 taper and Hyflex GPF size 15, .01 taper had the highest angle values (P < 0.05). The ProGlider had the lowest angle values in comparison with all the groups (P < 0.05) followed by Mtwo size 10, .04 taper. The Logic size 25, .01 taper had significantly higher angle of rotation values than ProGlider and Mtwo size 10, .04 taper (P < 0.05). CONCLUSION: The Logic size 25, .01 taper instrument made of conventional NiTi alloy had the highest torsional strength of all instruments tested. In addition, the ProGlider instrument manufactured from M-Wire alloy had the lowest angle of rotation to fracture in comparison with the other instruments. PMID- 29171881 TI - RNA N6-methyladenosine methyltransferase-like 3 promotes liver cancer progression through YTHDF2-dependent posttranscriptional silencing of SOCS2. AB - : Epigenetic alterations have contributed greatly to human carcinogenesis. Conventional epigenetic studies have predominantly focused on DNA methylation, histone modifications, and chromatin remodeling. Recently, diverse and reversible chemical modifications of RNAs have emerged as a new layer of epigenetic regulation. N6-methyladenosine (m6A) is the most abundant chemical modification of eukaryotic messenger RNA (mRNA) and is important for the regulation of mRNA stability, splicing, and translation. Using transcriptome sequencing, we discovered that methyltransferase-like 3 (METTL3), a major RNA N6-adenosine methyltransferase, was significantly up-regulated in human hepatocellular carcinoma (HCC) and multiple solid tumors. Clinically, overexpression of METTL3 is associated with poor prognosis of patients with HCC. Functionally, we proved that knockdown of METTL3 drastically reduced HCC cell proliferation, migration, and colony formation in vitro. Knockout of METTL3 remarkably suppressed HCC tumorigenicity and lung metastasis in vivo. On the other hand, using the CRISPR/dCas9-VP64 activation system, we demonstrated that overexpression of METTL3 significantly promoted HCC growth both in vitro and in vivo. Through transcriptome sequencing, m6A sequencing, and m6A methylated RNA immuno precipitation quantitative reverse-transcription polymerase chain reaction, we identified suppressor of cytokine signaling 2 (SOCS2) as a target of METTL3 mediated m6A modification. Knockdown of METTL3 substantially abolished SOCS2 mRNA m6A modification and augmented SOCS2 mRNA expression. We also showed that m6A mediated SOCS2 mRNA degradation relied on the m6A reader protein YTHDF2-dependent pathway. CONCLUSION: METTL3 is frequently up-regulated in human HCC and contributes to HCC progression. METTL3 represses SOCS2 expression in HCC through an m6A-YTHDF2-dependent mechanism. Our findings suggest an important mechanism of epigenetic alteration in liver carcinogenesis. (Hepatology 2018;67:2254-2270). PMID- 29171882 TI - Characterization of epitope specificities of reference antibodies used for the quantification of the birch pollen allergen Bet v 1. AB - BACKGROUND: Accurate allergen quantification is needed to document the consistency of allergen extracts used for immunotherapy. Herein, we characterize the epitope specificities of two monoclonal antibodies used in an ELISA for the quantification of the major birch pollen allergen Bet v 1, established as a reference by the BSP090 European project. METHODS: The ability of mAbs 5B4 and 6H4 to recognize Bet v 1 isoforms was addressed by immunochromatography. The capacity of each mAb to compete with patients' IgE for binding to Bet v 1 was measured by ELISA inhibition. Epitope mapping was performed by pepscan analysis, site-directed mutagenesis, and hydrogen/deuterium exchange-mass spectrometry. RESULTS: The 5B4 epitope corresponds to a peptide sequence (I56-K68) overlapping with the binding sites of patients' serum IgEs. Mutation of residues P59, E60, and K65 abolishes 5B4 binding to Bet v 1 and reduces the level of IgE recognition. In contrast, 6H4 recognizes a conformational epitope lying opposite to the 5B4 binding site, involving residues located in segments I44-K55 and R70 F79. Substitution of E45 reduces the binding capacity of 6H4, confirming that it is critical for the interaction. Both mAbs interact with >90% of Bet v 1 content present in the birch pollen extract, while displaying a weak cross-reactivity with other allergens of the PR-10 family. CONCLUSIONS: MAbs 5B4 and 6H4 recognize structurally distinct epitopes present in the vast majority of Bet v 1 isoforms. These results support the relevance as a reference method of the Bet v 1-specific quantitative ELISA adopted by the European Pharmacopoeia. PMID- 29171883 TI - A Call for Empirical Research on Uterine Transplantation and Reproductive Autonomy. AB - Uterine transplantation could give women who suffer from uterine factor infertility the possibility of experiencing gestation. Much of the ethical discussion about uterine transplantation has focused on whether research on it should even be pursued, but researchers are nevertheless moving forward with several uterine transplant research protocols. Scholars should therefore already be identifying and engaging in an intimate examination of the ethical realities of offering uterine transplantation in a clinical setting. Given the potential for the procedure to expand reproductive options for women, reproductive autonomy has been a primary principle underlying much of the ethical discourse about the hypothetical impact of uterine transplantation. Yet the factors that will affect whether uterine transplants promote or undermine a patients' reproductive autonomy if the procedure is integrated into clinical practice have yet to be rigorously explored. Focusing on the clinical realities of patient autonomy, I argue that empirical data exploring prospective recipients' motivations and their perceptions of the benefits of the procedure in the context of their lived experiences are critical to a robust analysis of the ethical dimensions of uterine transplantation. PMID- 29171884 TI - Autonomy in Tension: Reproduction, Technology, and Justice. AB - Respect for autonomy is a central value in reproductive ethics, but it can be a challenge to fulfill and is sometimes an outright puzzle to understand. If a woman requests the transfer of two, three, or four embryos during fertility treatment, is that request truly autonomous, and do clinicians disrespect her if they question that decision or refuse to carry it out? Add a commitment to justice to the mix, and the challenge can become more complex still. Is it unfair for insurance policies to exclude from coverage the costs of giving fertility to those who lack it or restoring fertility in those who have lost it? What does "just reproduction" look like in the face of multifarious understandings of both justice and autonomy and in light of increasingly complex and costly reproductive technologies? In today's dialogue about reproduction, medicine, and ethics in the United States, old ethical issues-such as whether women ought to be allowed to access pregnancy termination-are more contested than they have been in decades, while new technologies-like those used to edit the genes of human embryos-suggest that our species could face unprecedented questions about who should exist. As we considered the discussions accompanying these issues and contemplated a special report responding to them, we found ourselves consistently circling back to two ethical commitments: respect for autonomy and the pursuit of justice. As one of the nine essays in this collection asks, why should certain women receive help to establish a pregnancy while others are thrown in jail when they miscarry or their child is stillborn? Respect for autonomy is required where individuals have the ability to make fully informed and voluntary choices. Yet does respecting autonomy require acceding to all the choices of patients or consumers of medical care? We consider these and related questions in this special report from the Hastings Center Report. PMID- 29171885 TI - About The Hastings Center. PMID- 29171886 TI - Reproductive Rights without Resources or Recourse. AB - The U.S. Supreme Court declared procreation to be a fundamental right in the early twentieth century in a case involving Oklahoma's Habitual Criminal Sterilization Act, an act that permitted unconsented sterilization of individuals convicted of certain crimes. The right that the Court articulated in that case is a negative right: it requires that the government not place unjustified roadblocks in the way of people seeking to procreate, but it does not require the government to take positive steps to help people procreate if they wish to. I argue that a positive legal right is morally necessary in the United States, given the profound significance of procreation, the current barriers to access to care, and the related issues of individual and societal justice. I assume at the outset that the right to procreate should be expansive enough to include a right to noncoital reproduction. The absence of a positive right to procreate reflects not just constitutional tradition but also a governmental and societal commitment to a longstanding set of reproductive hierarchies by which those who fall outside of the traditional framing of family too frequently find their procreative dreams hindered. Reconceiving procreative rights to include a positive right would create greater opportunities to argue and lobby for increased access to technologies that are out of reach for many. PMID- 29171887 TI - Freezing Eggs and Creating Patients: Moral Risks of Commercialized Fertility. AB - There's no doubt that reproductive technologies can transform lives for the better. Infertile couples and single, lesbian, gay, intersex, and transgender people have the potential to form families in ways that would have been inconceivable years ago. Yet we are concerned about the widespread commercialization of certain egg-freezing programs, the messages they propagate about motherhood, the way they blur the line between care and experimentation, and the manipulative and exaggerated marketing that stretches the truth and inspires false hope in women of various ages. We argue that although reproductive technology, and egg freezing in particular, promise to improve women's care by offering more choices to achieve pregnancy and childbearing, they actually have the potential to be disempowering. First, commercial motives in the fertility industry distort women's medical deliberations, thereby restricting their autonomy; second, having the option to freeze their eggs can change the meaning of women's reproductive choices in a way that is limiting rather than liberating. PMID- 29171889 TI - The Shifting Landscape of Prenatal Testing: Between Reproductive Autonomy and Public Health. AB - Since the 1970s, prenatal testing has been integrated into many health care systems on the basis of two competing and largely irreconcilable rationales. The reproductive autonomy rationale focuses on nondirective counseling and consent as ways to ensure that women's decisions about testing and subsequent care are informed and free of undue pressures. It also represents an easily understandable and ethically convincing basis for widespread access to prenatal testing, since the value of autonomy is well established in Western bioethics and widely recognized by funders of health care. In contrast, the public health rationale approaches prenatal testing as designed to reduce the incidence of certain conditions in the population to reduce the burden of disease. This rationale emphasizes the societal consequences of reproduction and the aggregate impact of women's individual reproductive decisions on the overall health of future populations. In this essay, I argue that, despite what could be seen as a persistent failure to meet the ideals of reproductive autonomy, resisting the public health rationale as a basis for prenatal screening is ethically and pragmatically crucial. I recommend policy mechanisms that can enhance reproductive autonomy at a societal level to support choice at the individual level. PMID- 29171890 TI - Reproductive Autonomy and Regulation-Coexistence in Action. AB - On occasion, British in vitro fertilization practitioners look over the ocean to the practice of IVF and embryo research in the United States, wonder why these areas are subject to less regulation than in the United Kingdom, and ask how much less risky and more progressive IVF and embryo research might be if subject to additional federal, or at least state, regulation. To an American audience, imbued with the centuries-old spirit of independence, regulation and autonomy can seem in tension. From a British perspective, there is no necessary conflict. There is no dissent in the United Kingdom from the proposition that individual activities, services, and industries can be regulated and, at the same time, retain and exercise such autonomy as is their right within a safe sphere. From 1994 to 2002, I was the chair of the United Kingdom's Human Fertilisation and Embryology Authority, which regulates the practice of IVF and embryo research. The existence of the HFEA assures patients that safety and aspects of the practice of assisted reproduction are monitored, leaving them free to choose without worrying about danger, in the same way that the public may take only those drugs that have passed health and safety tests. I would propose that anxious and vulnerable patients do not have more autonomy in a less regulated, market-driven field. PMID- 29171891 TI - About the Special Report. PMID- 29171892 TI - Parenting in the Age of Preimplantation Gene Editing. AB - Medical science at its core aims to preserve health and eliminate disease, but a common theme in scientific discovery is the application of findings in ways that were not the primary intent. The development of diagnostic modalities to predict the health of resulting children has been a fundamental aim underpinning research into prenatal and preimplantation diagnostic modalities; however, the knowledge gained has in some cases been utilized for nonmedical purposes. As an example, amniocentesis developed to determine whether the pregnancy is chromosomally normal also provides information about the sex of the fetus, which normally does not affect health. The emerging gene-editing technologies that could be used to repair mutated disease-causing genes in an embryo will presumably also be able to be used to alter traits unrelated to disease. And yet, I will argue, the desire to preserve the mystery of reproduction remains a central value in humans' quest to reproduce. This yearning to maintain the mysteries will likely temper the development of strategies to alter our genome and affect the genetic identities of our offspring. In my experience as an obstetrician and reproductive endocrinology and infertility subspecialist, people want to have, not the best possible baby, but rather their own baby. PMID- 29171893 TI - Should Clinicians Set Limits on Reproductive Autonomy? AB - As a gynecologic surgeon with a focus on infertility, I frequently hold complex discussions with patients, exploring with them the risks and benefits of surgical options. In the past, we physicians may have expected our patients to simply defer to our expertise and choose from the options we presented. In our contemporary era, however, patients frequently request options not favored by their physicians and even some they've found themselves online. In reproductive endocrinology and infertility, the range of options that may be offered or that patients may themselves seek out is continuously widening. Physicians certainly seek to find the option that will result in the best outcome for their patients, but the information to guide us in achieving the best outcome can be vague or conflicting. Add to this the financial and emotional pressures bearing on patients seeking assisted reproduction. In this essay, I explore the extent to which clinicians in reproductive medicine should follow patient requests with which they disagree or instead try to persuade the patient to do something else or simply refuse outright to meet the request. And if persuasion is to be used, what would be legitimate methods? Clearly, coercion is unacceptable, but the line between persuasion and coercion can be elusive. At what point can or should clinicians resist such requests-and to what degree? PMID- 29171894 TI - The Future of Reproductive Autonomy. AB - In a project The Hastings Center is now running on the future of prenatal testing, we are encountering clear examples, both in established law and in the practices of individual providers, of failures to respect women's reproductive autonomy: when testing is not offered to certain demographics of women, for instance, or when the choices of women to terminate or continue pregnancies are prohibited or otherwise not supported. But this project also raises puzzles for reproductive autonomy. We have learned that some clinicians and patients do not discuss the fact that prenatal testing can lead to a decision about whether to terminate a pregnancy-they just don't talk about it. And while the decision whether to agree to prenatal screening and diagnostic testing is to be made with women's free and informed consent, many screening tests have been routinized in such a way that some women do not even recall agreeing to testing, while others feel that agreeing to testing is what their clinicians expect of them or that the testing is necessary to protect themselves and their families from the significant financial hardship of raising a child with a disability. In the face of these pressures, can one really say that women are freely choosing to undergo testing or are freely choosing to continue or terminate a pregnancy following receipt of test results? The reality of these pressures is requiring us to consider expanding the scope of our investigation beyond the clinical encounter to the broader context-to think harder about what reproductive autonomy means and how best to enhance it. PMID- 29171895 TI - How the Criminalization of Pregnancy Robs Women of Reproductive Autonomy. AB - In 2003, the South Carolina Supreme Court upheld the conviction of Regina McKnight, an African American woman who was convicted at the age of twenty-two for committing "homicide by child abuse." She became the first woman in the United States to be arrested, prosecuted, and convicted for experiencing a stillbirth. Rather than an outlier case in the annals of American jurisprudence that stretched law beyond reason while restraining compassion and justice, McKnight's conviction inspired similar prosecutions of other poor black women and then of other women. More than one-third of states consider pregnant women's illicit drug use a form of child abuse, resulting in unprecedented forms of criminal and civil punishment. Laws previously understood to protect pregnant women from domestic violence during pregnancy, such as fetal protection laws, now serve as the vehicles for prosecuting pregnant women. What these prosecutions and laws expose are the multitudinous ways in which the criminalization of poor pregnant women-and normalization of that criminalization, such that even doctors and nurses are expected to participate in it-serve to humiliate women, interfere with their reproductive health, and ultimately rob women of reproductive autonomy. PMID- 29171896 TI - A protocol for combining fluorescent proteins with histological stains for diverse cell wall components. AB - Higher plant function is contingent upon the complex three-dimensional (3D) architecture of plant tissues, yet severe light scattering renders deep, 3D tissue imaging very problematic. Although efforts to 'clear' tissues have been ongoing for over a century, many innovations have been made in recent years. Among them, a protocol called ClearSee efficiently clears tissues and diminishes chlorophyll autofluorescence while maintaining fluorescent proteins - thereby allowing analysis of gene expression and protein localisation in cleared samples. To further increase the usefulness of this protocol, we have developed a ClearSee based toolbox in which a number of classical histological stains for lignin, suberin and other cell wall components can be used in conjunction with fluorescent reporter lines. We found that a number of classical dyes are highly soluble in ClearSee solution, allowing the old staining protocols to be enormously simplified; these additionally have been unsuitable for co visualisation with fluorescent markers due to harsh fixation and clearing. Consecutive staining with several dyes allows 3D co-visualisation of distinct cell wall modifications with fluorescent proteins - used as transcriptional reporters or protein localisation tools - deep within tissues. Moreover, the protocol is easily applied on hand sections of different organs. In combination with confocal microscopy, this improves image quality while decreasing the time and cost of embedding/sectioning. It thus provides a low-cost, efficient method for studying thick plant tissues which are usually cumbersome to visualise. Our ClearSee-adapted protocols significantly improve and speed up anatomical and developmental investigations in numerous plant species, and we hope they will contribute to new discoveries in many areas of plant research. PMID- 29171897 TI - Structural whole-brain covariance of the anterior and posterior hippocampus: Associations with age and memory. AB - The hippocampus (HC) interacts with distributed brain regions to support memory and shows significant volume reductions in aging, but little is known about age effects on hippocampal whole-brain structural covariance. It is also unclear whether the anterior and posterior HC show similar or distinct patterns of whole brain covariance and to what extent these are related to memory functions organized along the hippocampal longitudinal axis. Using the multivariate approach partial least squares, we assessed structural whole-brain covariance of the HC in addition to regional volume, in young, middle-aged and older adults (n = 221), and assessed associations with episodic and spatial memory. Based on findings of sex differences in both memory and brain aging, we further considered sex as a potential modulating factor of age effects. There were two main covariance patterns: one capturing common anterior and posterior covariance, and one differentiating the two regions by capturing anterior-specific covariance only. These patterns were differentially related to associative memory while unrelated to measures of single-item memory and spatial memory. Although patterns were qualitatively comparable across age groups, participants' expression of both patterns decreased with age, independently of sex. The results suggest that the organization of hippocampal structural whole-brain covariance remains stable across age, but that the integrity of these networks decreases as the brain undergoes age-related alterations. PMID- 29171898 TI - I had no other option: Women, electroconvulsive therapy, and informed consent. AB - Electroconvulsive therapy (ECT) is a controversial procedure used in the management of depression. Whilst it may be administered under mental health legislation, it is usually given to people who voluntarily consent. At the practice level, the consent process for ECT requires a detailed explanation of the procedure. The person consenting must have capacity to make this decision, and consent must be given freely and without coercion. Research using a feminist narrative approach unexpectedly highlighted the issue of potential coercion in the context of explaining the procedure. In-depth interviews were used to understand seven women's accounts of deciding to receive ECT. A thematic analysis of their narratives uncovered a shared concern with how they consented to the treatment. Four subthemes were identified that related to the way in which they provided their consent: (i) 'Not enough information'; (ii) 'I had no other choice'; (iii) 'Just go along with it'; and (iv) 'Lacking capacity'. A consent process that includes elements of passive coercion and a lack of timely and appropriate information influences the way some women make decisions. These factors can disempower women at the point of decision-making. A practice shift is needed where women are enabled to have control over decisions. Further, there is a need to adhere more rigorously to noncoercive practice when obtaining consent. PMID- 29171899 TI - Well-being of nursing staff on specialized units for older patients with combined care needs. AB - WHAT IS ALREADY KNOWN ABOUT THE SUBJECT: Working in long-term care is seen as a stressful, physically and mentally demanding occupation, and thus, nursing staff are at risk for work and stress-related diseases. In older patients, psychiatric illnesses often occur in combination with physical illnesses, requiring nursing care that is specific to these combined care needs. The impact of caring for these patients on the mental well-being of nurses is unknown. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE: Nursing staff working on specialized units for patients with combined care needs experience high levels of self-efficacy in combination with strong feelings of self-rated competence. Although levels of burnout are relatively low, mental healthcare nursing staff is more at risk for burnout when working in specialized settings for patients with combined care needs than nursing home staff working in specialized settings for these patients. Nursing staff characteristics, such as years of working experience and age, seem more important in relation to staff well-being than patient characteristics in specialized settings for combined care needs. WHAT ARE THE IMPLICATIONS FOR PRACTICE: Staff well-being might benefit from specializing care, so that patients with similar care needs are placed together and care is focused. The presence of specialized care units for older patients with combined care needs can allow for both targeted and focused allocation of nursing staff to these units and provision of specific training. ABSTRACT: Introduction In older patients, psychiatric illnesses frequently exist in tandem with physical illnesses, requiring nursing care that is specific to these combined care needs. The impact of caring for these patients on the mental well-being of nursing staff is unknown. AIM: To investigate whether care characteristics of patients with combined care needs are related to the mental well-being of nursing staff. METHOD: Well-being of nursing staff was studied within a larger exploratory observational cross-sectional study that examined the differences and similarities of specialized combined care units in Dutch mental healthcare and nursing home settings. RESULTS: Nursing staff across settings, with more than 5 years of work experience, felt competent in caring for patients with combined care needs. No significant effects of care characteristics of patients with combined care needs on the work-related well-being of nursing staff were shown. Both mental health nursing staff and older employees, however, were found to be more at risk for burnout. IMPLICATIONS/CONCLUSION: Staff well-being might benefit from placing patients with combined care needs together, so care is focused. The presence of specialized care units can allow for both targeted and focused allocation of nursing staff to these units and provision of specific training.

AB - Saturation mutagenesis (SM) constitutes a widely used technique in the directed evolution of selective enzymes as catalysts in organic chemistry and in the manipulation of metabolic paths and genomes, but the quality of the libraries is far from optimal due to the inherent amino acid bias. Herein, it is shown how this fundamental problem can be solved by applying high-fidelity solid-phase chemical gene synthesis on silicon chips followed by efficient gene assembly. Limonene epoxide hydrolase was chosen as the catalyst in the model desymmetrization of cyclohexene oxide with the stereoselective formation of (R,R) and (S,S)-cyclohexane-1,2-diol. A traditional combinatorial PCR-based SM library, produced by simultaneous randomization at several residues by using a reduced amino acid alphabet, and the respective synthetic library were constructed and compared. Statistical analysis at the DNA level with massive sequencing demonstrates that, in the synthetic approach, 97 % of the theoretically possible DNA mutants are formed, whereas the traditional SM library contained only about 50 %. Screening at the protein level also showed the superiority of the synthetic library; many highly (R,R)- and (S,S)-selective variants being discovered are not found in the traditional SM library. With the prices of synthetic genes decreasing, this approach may point the way to future directed evolution. PMID- 29171901 TI - Current advances in aptamer-assisted technologies for detecting bacterial and fungal toxins. AB - Infectious diseases are among the common leading causes of morbidity and mortality worldwide. Associated with the emergence of new infectious diseases, the increasing number of antimicrobial-resistant isolates presents a serious threat to public health and hospitalized patients. A microbial pathogen may elicit several host responses and use a variety of mechanisms to evade host defences. These methods and mechanisms include capsule, lipopolysaccharides or cell wall components, adhesions and toxins. Toxins inhibit phagocytosis, cause septic shock and host cell damages by binding to host surface receptors and invasion. Bacterial and fungal pathogens are able to apply many different toxin dependent mechanisms to disturb signalling pathways and the structural integrity of host cells for establishing and maintaining infections Initial techniques for analysis of bacterial toxins were based on in vivo or in vitro assessments. There is a permanent demand for appropriate detection methods which are affordable, practical, careful, rapid, sensitive, efficient and economical. Aptamers are DNA or RNA oligonucleotides that are selected by systematic evolution of ligands using exponential enrichment (SELEX) methods and can be applied in diagnostic applications. This review provides an overview of aptamer-based methods as a novel approach for detecting toxins in bacterial and fungal pathogens. PMID- 29171902 TI - Early ecological outcomes of natural regeneration and tree plantations for restoring agricultural landscapes. AB - Mixed tree plantings and natural regeneration are the main restoration approaches for recovering tropical forests worldwide. Despite substantial differences in implementation costs between these methods, little is known regarding how they differ in terms of ecological outcomes, which is key information for guiding decision making and cost-effective restoration planning. Here, we compared the early ecological outcomes of natural regeneration and tree plantations for restoring the Brazilian Atlantic Forest in agricultural landscapes. We assessed and compared vegetation structure and composition in young (7-20 yr old) mixed tree plantings (PL), second-growth tropical forests established on former pastures (SGp), on former Eucalyptus spp. plantations (SGe), and in old-growth reference forests (Ref). We sampled trees with diameter at breast height (DBH) 1 5 cm (saplings) and trees at DBH > 5 cm (trees) in a total of 32 20 * 45 m plots established in these landscapes. Overall, the ecological outcomes of natural regeneration and restoration plantations were markedly different. SGe forests showed higher abundance of large (DBH > 20 cm) nonnative species, of which 98% were resprouting Eucalyptus trees, than SGp and PL, and higher total aboveground biomass; however, aboveground biomass of native species was higher in PL than in SGe. PL forests had lower abundance of native saplings and lianas than both naturally established second-growth forests, and lower proportion of animal dispersed saplings than SGe, probably due to higher isolation from native forest remnants. Rarefied species richness of trees was lower in SGp, intermediate in SGe and Ref and higher in PL, whereas rarefied species richness of saplings was higher in SG than in Ref. Species composition differed considerably among regeneration types. Although these forests are inevitably bound to specific landscape contexts and may present varying outcomes as they develop through longer time frames, the ecological particularities of forests established through different restoration approaches indicate that naturally established forests may not show similar outcomes to mixed tree plantings. The results of this study underscore the importance that restoration decisions need to be based on more robust expectations of outcomes that allow for a better analysis of the cost effectiveness of different restoration approaches before scaling-up forest restoration in the tropics. PMID- 29171903 TI - Public Response to a Near-Miss Nuclear Accident Scenario Varying in Causal Attributions and Outcome Uncertainty. AB - Many studies have investigated public reactions to nuclear accidents. However, few studies focused on more common events when a serious accident could have happened but did not. This study evaluated public response (emotional, cognitive, and behavioral) over three phases of a near-miss nuclear accident. Simulating a loss-of-coolant accident (LOCA) scenario, we manipulated (1) attribution for the initial cause of the incident (software failure vs. cyber terrorist attack vs. earthquake), (2) attribution for halting the incident (fail-safe system design vs. an intervention by an individual expert vs. a chance coincidence), and (3) level of uncertainty (certain vs. uncertain) about risk of a future radiation leak after the LOCA is halted. A total of 773 respondents were sampled using a 3 * 3 * 2 between-subjects design. Results from both MANCOVA and structural equation modeling (SEM) indicate that respondents experienced more negative affect, perceived more risk, and expressed more avoidance behavioral intention when the near-miss event was initiated by an external attributed source (e.g., earthquake) compared to an internally attributed source (e.g., software failure). Similarly, respondents also indicated greater negative affect, perceived risk, and avoidance behavioral intentions when the future impact of the near-miss incident on people and the environment remained uncertain. Results from SEM analyses also suggested that negative affect predicted risk perception, and both predicted avoidance behavior. Affect, risk perception, and avoidance behavior demonstrated high stability (i.e., reliability) from one phase to the next.

AB - A rhodium-catalyzed intramolecular acetyl-group transfer has been achieved through a "cut and sew" process. The challenge arises from the existence of different competitive pathways. Preliminary success has been achieved with unstrained enones that contain a biaryl linker. The use of an electron-rich N heterocycilc carbene (NHC) ligand is effective to inhibit undesired beta-hydrogen elimination. Various 9,10-dihydrophenanthrene derivatives can be prepared with excellent functional-group compatibility. The 13 C-labelling study suggests that the reaction begins with cleavage of the unstrained C-C bond, followed by migratory insertion and reductive elimination. PMID- 29171905 TI - Educational nurse-led lifestyle intervention for persons with mental illness. AB - Although persons with severe mental illness face an increased risk of mortality and of developing negative health outcomes, research has shown that lifestyle interventions can sufficiently support their health. In response, this study examined a nurse-led lifestyle intervention developed in cooperation with members of municipal and county councils to gauge its impact on the quality of life, cognitive performance, walking capacity, and body composition of persons with severe mental illness. Lasting 26 weeks and involving 38 persons with severe mental illness, the intervention prioritised two components: the interpersonal relationships of persons with severe mental illness, staff, and group leaders and group education about physical and mental health. Pre-post intervention measurements of quality of life collected with the Manchester Short Assessment of Quality of Life, cognitive performance with the Frontal Systems Behaviour Scale, walking capacity with a 6-min walk test, and body composition in terms of waist circumference and body mass index were analysed using a nonparametric test Wilcoxon signed-rank test. Results suggest that the intervention afforded significant improvements in the health-related variables of quality of life, cognitive performance, walking capacity, and waist circumference for persons with severe mental illness. However, long-term studies with control groups and that examine parameters related to cardiovascular risk factors are essential to ensure the sustained impact of the intervention.

AB - We investigated the association between the current use of individual sulphonylureas and the risk of a first-ever acute myocardial infarction (AMI) and all-cause mortality, in a population-based cohort study, using primary care data from the Clinical Practice Research Datalink database (2004-2012). New users (N = 121 869), aged >=18 years, with at least one prescription for a non-insulin antidiabetic agent were included. The first prescription defined start of follow up. Time-dependent Cox proportional hazard models were used to estimate the risk of a first-ever AMI and all-cause mortality associated with the use of individual sulphonylureas, and other non-insulin glucose-lowering drugs. No differences in risk of a first-ever AMI (adjusted hazard ratio [HR] 1.02, 95% confidence interval [CI] 0.70-1.50) or all-cause mortality (adjusted HR 0.97, 95% CI 0.80 1.17) were observed when comparing gliclazide use with non-gliclazide sulphonylurea use. Similar results were found for each individual sulphonylurea. As evidence is accumulating that gliclazide is no safer than other sulphonylureas, current guidelines suggesting superiority should be carefully evaluated. PMID- 29171908 TI - An estimation of US horse-owner/caregiver willingness-to-pay for daily use and infectious upper respiratory disease treatment options. AB - BACKGROUND: Equine injury and disease cause two types of costs for those financially responsible for treating and caring for the infected horse(s); direct costs of treating the horse and indirect cost of lost use of the horse for a period of time to the user of the horse (daily horse use). Indirect costs are more difficult to estimate but pose significant financial implications for equine owners/caregivers. Additionally, there exists a gap in existing research regarding the valuation of infectious treatment options in horses. OBJECTIVE: To estimate the value a US horse-owner/caregiver places on daily horse use and describe respondents' willingness-to-pay for various attributes of equine treatment options. STUDY DESIGN: Online questionnaire survey. METHODS: An online questionnaire was provided to equine-owners and caretakers, and owner demographic, horse care and horse use information from respondents were requested. Additionally, respondents were presented with hypothetical disease treatment options with the following attributes: daily dosage, number of days of rest required, route of administration and out-of-pocket cost to the owner/caretaker through a choice experiment. Data were analysed using a rank ordered logit analysis and willingness-to-pay estimates for daily use and treatment options were calculated. RESULTS: Results suggest that the average horse-owner with an uninsured and insured horse is willing to pay $12.07 (95% confidence interval: -$15.01, -$9.69) and $17.95 (95% confidence interval: $25.30, -$11.20) per day to reduce lost use days required (due to need for rest) respectively. Respondents showed preferences for oral administration over treatments requiring i.m. injections. MAIN LIMITATIONS: As this study employed an online survey it was subjected to self-selection bias and a sample size calculation was not performed. CONCLUSIONS: Veterinarians and pharmaceutical companies may use these results when promoting various treatment options to horse owners/caregivers and in product development. Additionally, promotion efforts may be targeted towards equine-owners with higher daily use values (owners with insured horses). PMID- 29171909 TI - LYS12 LysM receptor decelerates Phytophthora palmivora disease progression in Lotus japonicus. AB - Phytophthora palmivora is a devastating oomycete plant pathogen. We found that P. palmivora induces disease in Lotus japonicus and used this interaction to identify cellular and molecular events in response to this oomycete, which has a broad host range. Transcript quantification revealed that Lys12 was highly and rapidly induced during P. palmivora infection. Mutants of Lys12 displayed accelerated disease progression, earlier plant death and a lower level of defence gene expression than the wild type, while the defence program after chitin, laminarin, oligogalacturonide or flg22 treatment and the root symbioses with nitrogen-fixing rhizobia and arbuscular mycorrhiza were similar to the wild type. On the microbial side, we found that P. palmivora encodes an active chitin synthase-like protein, and mycelial growth is impaired after treatment with a chitin-synthase inhibitor. However, wheat germ agglutinin-detectable N-acetyl glucosamine (GlcNAc) epitopes were not identified when the oomycete was grown in vitro or while infecting the roots. This indicates that conventional GlcNAc-mers are unlikely to be produced and/or accumulate in P. palmivora cell walls and that LYS12 might perceive an unknown carbohydrate. The impact of Lys12 on progression of root rot disease, together with the finding that similar genes are present in other P. palmivora hosts, suggests that LYS12 might mediate a common early response to this pathogen.

METHODS: We performed a series of postmortem immunohistochemical and immunofluorescent stainings, as well as Western blot analyses, on cervical and lumbar sections of the spinal cord in patients diagnosed with HD (n = 11 of all grades of disease severity) along with sex- and age-matched healthy controls (n = 9). RESULTS: We observed that mHTT was preferably expressed within the anterior horn of the gray matter, in both cervical and lumbar sections. At the cellular level, mHTT aggregates were more often encountered in the extracellular matrix but could also be observed within cell bodies and neurites as well as within the endothelium of blood vessels with an increase in the density of small blood vessels in cervical sections of HD cases. These vasculature changes were accompanied with features of BSCB leakage, as assessed by the presence of increased levels of fibrinogen in the surrounding parenchyma and enhanced leukocyte infiltration. INTERPRETATION: This alteration in BSCB integrity may be explained, in part, by the dysregulation we found in some of the main proteins associated with it such as junctional adhesion molecule-1 and vascular endothelial cadherin. These observations have important implications for our understanding of HD pathology and may also have significant therapeutic implications. Ann Neurol 2017;82:981-994.

AB - BACKGROUND: Buckwheat (Fagopyrum esculentum) has become increasingly popular as a healthy food in Europe. However, for sensitized individuals, consumption can cause anaphylactic reactions. The aim of this study was to identify individual well-characterized buckwheat allergens for component-resolved diagnosis. METHODS: Patients were selected by positive skin prick test to buckwheat and divided into two groups: (1) sensitized to buckwheat without clinical symptoms and (2) buckwheat allergy. Buckwheat proteins were extracted from raw buckwheat seeds, purified applying a combination of protein precipitation and chromatographic methods, and analyzed by IgE immunoblotting and ELISA. RESULTS: Buckwheat allergic patients had a significantly larger median skin prick test weal diameter for buckwheat than the sensitized group and the positive control. Also, IgE immunoblotting clearly showed a distinct pattern in sera from allergic patients when compared to sensitized individuals. Several IgE-reactive proteins were purified from crude buckwheat extract, namely legumin (Fag e 1 plus its large subunit), Fag e 2 (2S albumin), and newly identified Fag e 5 (vicilin-like) as well as hevein-like antimicrobial peptides, designated Fag e 4. All four allergens showed superior diagnostic precision compared to extract-based ImmunoCAP with high sensitivity as well as high specificity. CONCLUSIONS: Patients with clinical symptoms clearly show a distinct allergen recognition pattern. We characterized a buckwheat vicilin-like protein as a new relevant marker allergen, designated Fag e 5. Additionally, another new allergen, Fag e 4, potentially important for cross-reactivity to latex was added to the allergen panel of buckwheat. Further, our data show that the full-length legumin comprising both, large and small subunit should be applied for component-resolved diagnosis. Our data indicate that concomitant sensitization to legumin, Fag e 2 and Fag e 5, predicts buckwheat allergy.

AB - OBJECTIVE: Prospective data on the use of granulocyte-colony-stimulating factor (G-CSF) in non-Hodgkin's lymphoma and its aggressive subtypes, including diffuse large B-cell lymphoma (DLBCL), are limited. MONITOR-GCSF is a pan-European, multicenter, prospective, observational study aiming to describe treatment patterns and clinical outcomes in patients receiving biosimilar filgrastim in the prophylaxis of chemotherapy-induced neutropenia (CIN) and febrile neutropenia (FN). METHODS: This analysis describes patient characteristics, treatment patterns, and outcomes for 245 patients with stage 3 or 4 DLBCL receiving <=6 chemotherapy cycles as part of MONITOR-GCSF study, including patients aged >=65 years and >=70 years. Outcomes of interest included the incidence of CIN and FN, antibiotic prophylaxis, biosimilar filgrastim prophylaxis, and adverse events (AEs). RESULTS: MONITOR-GCSF included 245 patients with DLBCL. Of these patients, 87 (35.5%) experienced one or more CIN (any grade) episode and 24 (9.8%) experienced FN (any grade). The most frequent AE reported was bone pain (n = 7, 2.9%), followed by arthralgia (n = 2, 0.8%) and back pain (n = 2, 0.8%). CONCLUSION: In real-life practice, biosimilar filgrastim demonstrated clinical effectiveness and safety in patients with DLBCL. The large percentage of patients aged >=65 years adds to the evidence on how to best treat older patients with DLBCL receiving myelosuppressive chemotherapy. PMID- 29171914 TI - Risk of inferior alveolar nerve injury with coronectomy vs surgical extraction of mandibular third molars-A comparison of two techniques and review of the literature. AB - The removal of mandibular third molar teeth is one of the most common oral surgical procedures. In a significant number of patients, it carries a degree of associated morbidity, including damage to the inferior alveolar nerve (IAN). For this reason, practitioners desire the most up-to-date guidance on the most appropriate technique, informed by the best available evidence that will produce the lowest incidence of iatrogenic complications. The aim of this study was to perform a systematic review comparing the effect of coronectomy vs complete surgical extraction of mandibular third molar teeth on the risk of IAN injury and other complications in adults. Studies were identified through Embase (1980-2016) and Ovid MEDLINE (1946-2016) database searches. Search terms included coronectomy, partial root removal, deliberate vital root retention, odontectomy, surgical removal, surgical extraction, complete tooth extraction and extract. Limits of the study included humans, English language and randomised controlled trials (RCTs). Only RCTs comparing IAN damage associated with surgical extraction of mandibular third molars vs coronectomy were included. From our database searches, we identified two unique RCTs matching the inclusion criteria. Both evaluated patients who had specific radiographic signs of intimate relationships with the IAN. Upon detailed analysis, the studies were noted to exhibit a high risk of bias in many categories, thereby rendering their results inconclusive. Although evidence from two RCTs suggests that coronectomy can reduce the risk of IAN injury compared to surgical removal of high-risk mandibular third molars, the quality of evidence is insufficient to provide definitive conclusions regarding the preferred technique. PMID- 29171916 TI - Distribution and clinical determinants of time-to-positivity of blood cultures in patients with neutropenia. AB - OBJECTIVES: Blood cultures (BCs) are essential in the evaluation of neutropenic fever. Modern BC systems have significantly reduced the time-to-positivity (TTP) of BC. This study explores the probability of bacteraemia when BCs have remained negative for different periods of time. METHODS: All adult patients with neutropenia and bacteraemia were included (January 2012-February 2016). Predictive clinical factors for short (<=16 hours) and long (>24 hours) TTP were determined. The residual probability of bacteraemia was estimated for the scenario of negative BC 24 hours after collection. RESULTS: The cohort consisted of 154 patients, accounting for 190 episodes of bacteraemia. Median age of 61 years, 60.5% were male. In 123 (64.7%) episodes, BC yielded a single Gram positive micro-organism and in 49 (25.8%) a Gram-negative micro-organism (median TTP 16.7, 14.5 hours respectively, P < .01). TTP was <=24 hours in 91.6% of episodes. Central line-associated bacteraemia was associated with long TTP. The probability of bacteraemia if BC had remained negative for 24 hours was 1%-3%. CONCLUSIONS: The expected TTP offers guidance in the management of patients with neutropenia and suspected bacteraemia. The knowledge of negative BC can support a change in working diagnosis, and impact clinical decisions as soon as 24 hours after BC collection. PMID- 29171915 TI - Targeting hypersensitive corticostriatal terminals in restless legs syndrome. AB - OBJECTIVE: The first aim was to demonstrate a previously hypothesized increased sensitivity of corticostriatal glutamatergic terminals in the rodent with brain iron deficiency (BID), a pathogenetic model of restless legs syndrome (RLS). The second aim was to determine whether these putative hypersensitive terminals could constitute a significant target for drugs effective in RLS, including dopamine agonists (pramipexole and ropinirole) and alpha2 delta ligands (gabapentin). METHODS: A recently introduced in vivo optogenetic-microdialysis approach was used, which allows the measurement of the extracellular concentration of glutamate upon local light-induced stimulation of corticostriatal glutamatergic terminals. The method also allows analysis of the effect of local perfusion of compounds within the same area being sampled for glutamate. RESULTS: BID rats showed hypersensitivity of corticostriatal glutamatergic terminals (lower frequency of optogenetic stimulation to induce glutamate release). Both hypersensitive and control glutamatergic terminals were significant targets for locally perfused pramipexole, ropinirole, and gabapentin, which significantly counteracted optogenetically induced glutamate release. The use of selective antagonists demonstrated the involvement of dopamine D4 and D2 receptor subtypes in the effects of pramipexole. INTERPRETATION: Hypersensitivity of corticostriatal glutamatergic terminals can constitute a main pathogenetic mechanism of RLS symptoms. Selective D4 receptor agonists, by specifically targeting these terminals, should provide a new efficient treatment with fewer secondary effects. Ann Neurol 2017;82:951-960. PMID- 29171918 TI - Asphyxiated neonates who received active therapeutic hypothermia during transport had higher rates of hypocapnia than controls. AB - AIM: We investigated the association between active hypothermia and hypocapnia in neonates with moderate-to-severe hypoxic-ischaemic encephalopathy (HIE) transported after birth. METHODS: This was a retrospective cohort study of neonates with HIE born between 2007 and 2011 and transported to Semmelweis University, Hungary, for hypothermia treatment before and after we introduced active cooling during transport in 2009. Of these, 71 received intensive care plus controlled active hypothermia during transport, while the 46 controls just received standard intensive care. Incident hypocapnia was defined as a partial pressure of carbon-dioxide (pCO2 ) that decreased below 35 mm Hg during transport. Multivariable logistic regression investigated the relationship between hypothermia and incident hypocapnia. RESULTS: Incident hypocapnia was more frequent in the actively cooled transport group (36.6%) than control group (17.4%; p = 0.025). pCO2 decreased from a median of 45 to 35 mm Hg (p < 0.0001) in the intervention group, but remained unchanged in the controls. After adjusting for confounders, hypothermia remained an independent risk factor for hypocapnia with an odds ratio (OR) of 4.23 and 95% confidence interval (95% CI) of 1.30-13.79. Sedation was associated with a reduction in OR of hypocapnia, at 0.35 (95% CI 0.12-0.98). CONCLUSIONS: Hypothermia increased the risk of hypocapnia in neonates with HIE during transport. PMID- 29171917 TI - Increasing motor neuron excitability to treat weakness in sepsis. AB - OBJECTIVE: Weakness induced by critical illness (intensive care unit acquired weakness) is a major cause of disability in patients and is currently untreatable. We recently identified a defect in repetitive firing of lower motor neurons as a novel contributor to intensive care unit acquired weakness. To develop therapy for intensive care unit acquired weakness, it was necessary to determine the mechanism underlying the defect in repetitive firing. METHODS: Both computer simulation and in vivo dynamic voltage clamp of spinal motor neurons in septic rats were employed to explore potential mechanisms underlying defective repetitive firing. RESULTS: Our results suggest alteration in subthreshold voltage-activated currents might be the mechanism underlying defective repetitive firing. It has been shown previously that pharmacologic activation of serotonin receptors on motor neurons increases motor neuron excitability, in part by enhancing subthreshold voltage-activated inward currents. Administration of a U.S. Food and Drug Administration-approved serotonin agonist (lorcaserin) to septic rats greatly improved repetitive firing and motor unit force generation. INTERPRETATION: Our findings suggest activation of serotonin receptors with lorcaserin may provide the first ever therapy for intensive care unit acquired weakness in patients.

AB - Covalent organic frameworks (COFs) are promising for catalysis, sensing, gas storage, adsorption, optoelectricity, etc. owning to the unprecedented combination of large surface area, high crystallinity, tunable pore size, and unique molecular architecture. Although COFs are in their initial research stage, progress has been made in the design and synthesis of COF-based electrocatalysis for the oxygen reduction reaction, oxygen evolution reaction, hydrogen evolution reaction, and CO2 reduction in energy conversion and fuel generation. Design principles are also established for some of the COF materials toward rational design and rapid screening of the best electrocatalysts for a specific application. Herein, the recent advances in the design and synthesis of COF-based catalysts for clean energy conversion and storage are presented. Future research directions and perspectives are also being discussed for the development of efficient COF-based electrocatalysts. PMID- 29171920 TI - Doing what we can, but knowing our place: Being an ally to promote consumer leadership in mental health. AB - Consumer participation in all aspects of mental health services is clearly articulated as an expectation of contemporary mental health policy. Consumer leadership has been demonstrated to be beneficial to mental health services. Barriers to implementation have limited the realization of this goal. In this discursive paper, we argue that non-consumers who support consumer partnerships and leadership (known as 'allies') have an important role to play in facilitating and supporting consumers in leadership roles. Allies currently have more potential to influence resource allocation, and might be viewed more credibly by their peers than consumer leaders themselves. We call for allies to ensure their role is one of support and facilitation (doing what they can), rather than directing the content or speaking on behalf of the consumer movement (knowing their place). In the present study, we address the importance of allies for the consumer movement. It proposes some 'rules of engagement' to ensure that allies do not intentionally or otherwise encroach on consumer knowledge and expertise, so that they maintain the important position of supporting consumers and facilitating the valuing and use of consumer knowledge, expertise, and ultimately, leadership. PMID- 29171921 TI - Developing a Clinically Relevant Tissue Engineered Heart Valve-A Review of Current Approaches. AB - Tissue engineered heart valves (TEHVs) have the potential to address the shortcomings of current implants through the combination of cells and bioactive biomaterials that promote growth and proper mechanical function in physiological conditions. The ideal TEHV should be anti-thrombogenic, biocompatible, durable, and resistant to calcification, and should exhibit a physiological hemodynamic profile. In addition, TEHVs may possess the capability to integrate and grow with somatic growth, eliminating the need for multiple surgeries children must undergo. Thus, this review assesses clinically available heart valve prostheses, outlines the design criteria for developing a heart valve, and evaluates three types of biomaterials (decellularized, natural, and synthetic) for tissue engineering heart valves. While significant progress has been made in biomaterials and fabrication techniques, a viable tissue engineered heart valve has yet to be translated into a clinical product. Thus, current strategies and future perspectives are also discussed to facilitate the development of new approaches and considerations for heart valve tissue engineering. PMID- 29171922 TI - Less means more: The magnitude of synaptic plasticity along the hippocampal dorso ventral axis is inversely related to the expression levels of plasticity-related neurotransmitter receptors. AB - The dorsoventral axis of the hippocampus exhibits functional differentiations with regard to (spatial Vs emotional) learning and information retention (rapid encoding Vs long-term storage), as well as its sensitivity to neuromodulation and information received from extrahippocampal structures. The mechanisms that underlie these differentiations remain unclear. Here, we explored neurotransmitter receptor expression along the dorsoventral hippocampal axis and compared hippocampal synaptic plasticity in the CA1 region of the dorsal (DH), intermediate (IH) and ventral hippocampi (VH). We observed a very distinct gradient of expression of the N-methyl-D-aspartate receptor GluN2B subunit in the Stratum radiatum (DH< IH< VH). A similar distribution gradient (DH< IH< VH) was evident in the hippocampus for GluN1, the metabotropic glutamate receptors mGlu1 and mGlu2/3, GABAB and the dopamine-D1 receptor. GABAA exhibited the opposite expression relationship (DH > IH > VH). Neurotransmitter release probability was lowest in DH. Surprisingly, identical afferent stimulation conditions resulted in hippocampal synaptic plasticity that was the most robust in the DH, compared with IH and VH. These data suggest that differences in hippocampal information processing and synaptic plasticity along the dorsoventral axis may relate to specific differences in the expression of plasticity-related neurotransmitter receptors. This gradient may support the fine-tuning and specificity of hippocampal synaptic encoding. PMID- 29171923 TI - Clinical and genetic findings in children with central nervous system arteriovenous fistulas. AB - OBJECTIVE: To assess the spectrum of genetic anomalies in a cohort of children presenting at least one cerebral or spinal pial arteriovenous fistula (AVF), and to describe their clinical characteristics. METHODS: From 1988 to 2016, all consecutive patients with at least one cerebral or spinal pial AVF were screened for genetic disease. All patients aged <18 years were included. Symptoms associated with AVF were recorded: heart failure, neurological deficit/seizure, and hemorrhage. The outcome was assessed using the modified Rankin Scale and school performance in children with cerebral AVF and the American Spinal Injury Association impairment scale in children with spinal AVF. RESULTS: Forty-three children were included. Twenty-five children were male and 18 were female. A germline mutation was identified in 23 probands (53.5 +/- 14.9%): 8 in ENG (34.8 +/- 14.2%), 1 in ACVRL1 (4.3 +/- 6%) leading to a diagnosis of HHT, and 14 in RASA1 (60.9 +/- 14.4%) leading to a diagnosis of capillary malformation/arteriovenous malformation type 1. No EphB4 gene mutation was identified. HHT patients presented a significantly lower rate of heart failure at diagnosis (p = 0.047). A trend toward an increased bleeding rate at presentation was observed in HHT (p = 0.069) and an increased rate of giant venous pouch in children in whom no mutation was identified (p = 0.097). Finally, an association with RASA1 mutation was observed in children with associated skin capillary hemangioma (p < 0001). INTERPRETATION: These results highlight the importance of genetic testing in this setting in view of the high frequency of gene mutations in pediatric cerebrospinal AVFs, and show the predominance of RASA1 over HHT mutations.

AB - Nanoscale spin crossover materials capable of undergoing reversible switching between two electronic configurations with markedly different physical properties are excellent candidates for various technological applications. In particular, they can serve as active materials for storing and processing information in photonic, mechanical, electronic, and spintronic devices as well as for transducing different forms of energy in sensors and actuators. In this progress report, a brief overview on the current state-of-the-art of experimental and theoretical studies of nanomaterials displaying spin transition is presented. Based on these results, a detailed analysis and discussions in terms of finite size effects and other phenomena inherent to the reduced size scale are provided. Finally, recent research devices using spin crossover complexes are highlighted, emphasizing both challenges and prospects. PMID- 29171925 TI - Clinical and photobiological response in eight patients with solar urticaria under treatment with omalizumab, and review of the literature. AB - BACKGROUND: Solar urticaria (SU) is a rare photodermatosis. Treatment is challenging, and outcomes are often disappointing. Omalizumab is an anti-IgE, currently approved for treatment of chronic spontaneous urticaria. We sought to evaluate therapy with omalizumab in refractory SU and describe predictive factors for response. MATERIALS/METHODS: Patients with refractory SU under treatment with omalizumab were included in this study. Clinical outcome was evaluated using the Urticaria Activity Score 7 (UAS7), Dermatology Life Quality Index (DLQI) and Pruritus Visual Analogue Scale (VAS). Complete clinical response (CCR) was defined as having an UAS7 = 0, DLQI <6 and VAS = 0. Phototesting was performed and compared to baseline. We performed a PubMed search to identify reported cases of SU in adults treated with omalizumab, analysing their characteristics in order to predict response to omalizumab. RESULTS: Eight patients were included. Median age was 45.5 years (range, 23-64). Light spectrum most commonly implicated was UV A. Clinical outcomes: 89% (7/8) achieved CCR with omalizumab. Phototesting was normal in 42.8% (3/7) of them. In our review, we identified 38 patients (including the current case series), and 68.4% showed favourable outcomes with omalizumab. Median time since onset of SU was lower in responders. CONCLUSIONS: Omalizumab can be an effective treatment in refractory SU. PMID- 29171926 TI - Episodic autobiographical memory is associated with variation in the size of hippocampal subregions. AB - Striking individual differences exist in the human capacity to recollect past events, yet, little is known about the neural correlates of such individual differences. Studies investigating hippocampal volume in relation to individual differences in laboratory measures of episodic memory in young adults suggest that whole hippocampal volume is unrelated (or even negatively associated) with episodic memory. However, anatomical and functional specialization across hippocampal subregions suggests that individual differences in episodic memory may be linked to particular hippocampal subregions, as opposed to whole hippocampal volume. Given that the DG/CA2/3 circuitry is thought to be especially critical for supporting episodic memory in humans, we predicted that the volume of this region would be associated with individual variability in episodic memory. This prediction was supported using high-resolution MRI of the hippocampal subfields and measures of real-world (autobiographical) episodic memory. In addition to the association with DG/CA2/3 , we further observed a relationship between episodic autobiographical memory and subiculum volume, whereas no association was observed with CA1 or with whole hippocampal volume. These findings provide insight into the possible neural substrates that mediate individual differences in real-world episodic remembering in humans. PMID- 29171927 TI - Growth of Black Phosphorus Nanobelts and Microbelts. AB - Black phosphorus nanobelts are fabricated with a one-step solid-liquid-solid reaction method under ambient pressure, where red phosphorus is used as the precursor instead of white phosphorus. The thickness of the as-fabricated nanobelts ranges from micrometers to tens of nanometers as studied by scanning electron microscopy. Energy dispersive X-ray spectroscopy and X-ray diffraction indicate that the nanobelts have the composition and the structure of black phosphorus, transmission electron microscopy reveals a typical layered structure stacked along the b-axis, and scanning transmission electron microscopy with energy dispersive X-ray spectroscopy analysis demonstrates the doping of bismuth into the black phosphorus structure. The nanobelt can be directly measured in scanning tunneling microscopy in ambient conditions. PMID- 29171928 TI - Functionalizing PLGA and PLGA Derivatives for Drug Delivery and Tissue Regeneration Applications. AB - Poly(lactic-co-glycolic) acid (PLGA) is one of the most versatile biomedical polymers, already approved by regulatory authorities to be used in human research and clinics. Due to its valuable characteristics, PLGA can be tailored to acquire desirable features for control bioactive payload or scaffold matrix. Moreover, its chemical modification with other polymers or bioconjugation with molecules may render PLGA with functional properties that make it the Holy Grail among the synthetic polymers to be applied in the biomedical field. In this review, the physical-chemical properties of PLGA, its synthesis, degradation, and conjugation with other polymers or molecules are revised in detail, as well as its applications in drug delivery and regeneration fields. A particular focus is given to successful examples of products already on the market or at the late stages of trials, reinforcing the potential of this polymer in the biomedical field.

AB - An integrated analysis was performed with data from 4 phase 2 and phase 3 studies of tofogliflozin in which patients with type 2 diabetes mellitus received the sodium-glucose cotransporter 2 inhibitor tofogliflozin for up to 24 weeks. Sex differences, baseline haemoglobin A1c (HbA1c) and serum uric acid (UA) levels, and log10 -transformed urinary N-acetyl-beta-D-glucosaminidase ratio were significantly correlated with the reduction in serum UA levels at both 4 and 24 weeks in multivariate analysis (respectively, P < .0001). The decrease in HbA1c levels was greatest in the group with the highest baseline HbA1c level (quartile 4; HbA1c > 8.6%) and lowest in the group with the lowest baseline HbA1c level (quartile 1; HbA1c <= 7.4%). The decrease in serum UA levels was greatest in the quartile 1 group and lowest in the quartile 4 group. In most groups, the maximum decrease in serum UA levels was seen in the first 4 weeks, while the maximum decrease in HbA1c was seen at week 24. Thus, serum UA levels were significantly decreased in patients with moderate HbA1c levels. PMID- 29171929 TI - AHNS Series: Do you know your guidelines? Principles of treatment for locally advanced or unresectable head and neck squamous cell carcinoma. AB - This article is a continuation of the "Do You Know Your Guidelines" series, initiated by the Education committee of the American Head and Neck Society. Treatment guidelines for advanced head and neck squamous cell carcinoma are reviewed here, including the critical roles of radiotherapy, chemotherapy, and the recent application of immunotherapy agents. We will be limiting this discussion to include cancers of the oral cavity, oropharynx, hypopharynx, and larynx. It should be noted that much of the article pertains to human papillomavirus (HPV)-negative oropharyngeal cancer where applicable, as HPV positive oropharyngeal squamous cell carcinoma carries a different natural history, different prognosis, and now different staging criteria. Additionally, the article will not include information on nasopharyngeal or sinus cancers, as these latter topics are covered in separate "Do you know your guidelines?" installments and these diagnoses carry somewhat different approaches to diagnosis and management that diverge from the focus of this article. PMID- 29171932 TI - Extremely Small Pyrrhotite Fe7 S8 Nanocrystals with Simultaneous Carbon Encapsulation for High-Performance Na-Ion Batteries. AB - Na/FeSx batteries have remarkable potential applicability due to their high theoretical capacity and cost-effectiveness. However, realization of high power capability and long-term cyclability remains a major challenge. Herein, ultrafine Fe7 S8 @C nanocrystals (NCs) as a promising anode material for a Na-ion battery that addresses the above two issues simultaneously is reported. An Fe7 S8 core with quantum size (~10 nm) overcomes the kinetic and thermodynamic constraints of the Na-S conversion reaction. In addition, the high degree of interconnection through carbon shells improves the electronic transport along the structure. As a result, the Fe7 S8 @C NCs electrode achieves excellent power capability of 550 mA h g-1 (~79% retention of its theoretical capacity) at a current rate of 2700 mA g 1 . Furthermore, a conformal carbon shell acts as a buffer layer to prevent severe volume change, which provides outstanding cyclability of ~447 mA h g-1 after 1000 cycles (~71% retention of the initial charge capacity). PMID- 29171933 TI - Transpalpebral ultrasonographic measurement of the optic nerve sheath diameter in healthy dogs. AB - OBJECTIVE: To develop a reference range for ultrasonographically measured optic nerve sheath diameter (ONSD-US) in dogs. We hypothesized that ONSD-US can be measured reliably and is associated with weight but not age, sex, or body condition score (BCS), and that the relationship between weight and ONSD-US in dogs is allometric due to canine size variations. DESIGN: Prospective, observational study. SETTING: University teaching hospital. ANIMALS: Seventy eight healthy adult dogs. INTERVENTIONS: The ONSD was measured by a standardized transpalpebral approach. MEASUREMENTS AND MAIN RESULTS: Regression analysis showed the relationship between weight and ONSD was better fit with a linear model (R2 = 0.8510) than an allometric model (R2 = 0.7917). Multiple regression analysis showed ONSD is associated with weight (P < 0.0001), age (P = 0.0021), and BCS (P = 0.0007), but not with sex. Dominance analysis showed 94.6% of the variance explained by the model was due to weight. Intraclass correlation coefficient (ICC) analysis showed excellent interobserver (ICC = 0.9338-0.9608) and intraobserver (ICC = 0.9893) reliability. CONCLUSIONS: These results suggest that ONSD-US may be reliably measured in dogs using our described transpalpebral approach, and we have calculated prediction intervals based on body weight. Future studies are needed to determine if ONSD-US measurements are associated with intracranial hypertension as shown in human medicine. PMID- 29171934 TI - Design, Synthesis, and Evaluation of omega-(Isothiocyanato)alkylphosphinates and Phosphine Oxides as Antiproliferative Agents. AB - A series of 21 novel, structurally diverse omega (isothiocyanato)alkylphosphinates and phosphine oxides (ITCs) were designed and synthesized in moderate to good yields. The synthesized compounds were evaluated for in vitro antiproliferative activity using LoVo and LoVo/DX cancer cell lines. The biological activity of the synthesized compounds was higher than that of natural isothiocyanates such as benzyl isothiocyanate or sulforaphane. The antiproliferative activity of selected ITCs was also tested on selected cancer cell lines: A549, MESSA and MESSA/DX-5, HL60 and HL60MX2, BALB/3T3, and 4T1. These compounds were assessed for their mechanism of action as inducers of cell cycle arrest and apoptosis. Ethyl (6-isothiocyanatohexyl)(phenyl)phosphinate (71) was tested in vivo on the 4T1 cell line and demonstrated moderate antitumor activity, similar to that benzyl isothiocyanate and cyclophosphamide. PMID- 29171935 TI - Single molecule real-time DNA sequencing of HLA genes at ultra-high resolution from 126 International HLA and Immunogenetics Workshop cell lines. AB - The hyperpolymorphic HLA genes play important roles in disease and transplantation and act as genetic markers of migration and evolution. A panel of 107 B-lymphoblastoid cell lines (B-LCLs) was established in 1987 at the 10th International Histocompatibility Workshop as a resource for the immunogenetics community. These B-LCLs are well characterised and represent diverse ethnicities and HLA haplotypes. Here we have applied Pacific Biosciences' Single Molecule Real-Time (SMRT) DNA sequencing to HLA type 126 B-LCL, including the 107 International HLA and Immunogenetics Workshop (IHIW) cells, to ultra-high resolution. Amplicon sequencing of full-length HLA class I genes (HLA-A, -B and C) and partial length HLA class II genes (HLA-DRB1, -DQB1 and -DPB1) was performed. We typed a total of 931 HLA alleles, 895 (96%) of which were consistent with the typing in the IPD-IMGT/HLA Database (Release 3.27.0, January 20, 2017), with 595 (64%) typed at a higher resolution. Discrepant types, including novel alleles (n = 10) and changes in zygosity (n = 13), as well as previously unreported types (n = 34) were observed. In addition, patterns of linkage disequilibrium were distinguished by four-field resolution typing of HLA B and HLA-C. By improving and standardising the HLA typing of these B-LCLs, we have ensured their continued usefulness as a resource for the immunogenetics community in the age of next generation DNA sequencing. PMID- 29171936 TI - BRAF internal deletions and resistance to BRAF/MEK inhibitor therapy. AB - BRAF and MEK inhibitors have improved clinical outcomes in advanced, BRAFV600 mutated melanomas. Acquired resistance occurs in most patients, with numerous and diverse drivers. We obtained pretreatment and progression biopsies from a patient who progressed on dabrafenib and trametinib. In addition to a preserved BRAFV600E mutation, an internal deletion (rearrangement) of BRAF was observed in the progression sample. This deletion involved exons 2-8, which includes the Ras binding domain, and is analogous to previously documented BRAF fusions and splice variants known to reactivate RAS-RAF-MEK-ERK signaling. In a large cohort of melanomas, 10 additional internal deletions were identified (0.4% of all melanomas; nine of which had concurrent BRAF mutations), as well as sporadically in other tumor types. Thus, we describe a novel mechanism of resistance to BRAF and MEK inhibition.

AB - AIMS/INTRODUCTION: To evaluate the incidence rate of and identify factors associated with severe hypoglycemic episodes in patients with treated type 2 diabetes mellitus. MATERIALS AND METHODS: Using Diagnosis Procedure Combination hospital-based medical database, we carried out a retrospective cohort study to assess the incidence rate of severe hypoglycemia in treated type 2 diabetes mellitus patients. We evaluated the associations between severe hypoglycemia and age, sex, complications, and current use of insulin or sulfonylurea (SU) in a nested case-control study. RESULTS: Of 166,806 eligible patients, 1,242 had episodes of severe hypoglycemia during the observational period. The incidence rate of the first hypoglycemic events was 3.70/1,000 patient years. Based on the nested case-control analysis, age was associated with hypoglycemic events with adjusted odds ratios (ORs) of 1.64 or 65-74-year-old patients and 3.79 for >=75 year-old patients in comparison with 20-64-year-old patients. Comorbidities, such as cognitive impairment, cancer, macrovascular disease and diabetic complications (retinopathy, nephropathy and neuropathy), were associated with severe hypoglycemia, with adjusted ORs ranging from 1.25 to 3.80. Severe hypoglycemic events also increased in patients with current use of both SU and insulin, either SU or insulin, with adjusted ORs of 18.36, 6.31 or 14.07, respectively, compared with patients with other antihyperglycemic agents. In patients with an SU glimepiride, adjusted ORs increased dose-dependently from 3.65 (<=1 mg) to 13.34 (>2 mg). CONCLUSIONS: The incidence rate of severe hypoglycemia in this cohort was 3.70/1,000 patient years. Age, cognitive impairment, cancer, diabetic complications, current use of insulin + SU and SU dosage were identified as risk factors for severe hypoglycemia.

AB - Increasing the environmental benignity of lithium-ion batteries is one of the greatest challenges for their large-scale deployment. Toward this end, we present herein a strategy to enable the aqueous processing of high-voltage LiNi0.5 Mn1.5 O4 (LNMO) cathodes, which are considered highly, if not the most, promising for the realization of cobalt-free next-generation lithium-ion cathodes. Combining the addition of phosphoric acid with the cross-linking of sodium carboxymethyl cellulose by means of citric acid, aqueously processed electrodes with excellent performance are produced. The combined approach offers synergistic benefits, resulting in stable cycling performance and excellent coulombic efficiency (98.96 %) in lithium-metal cells. Remarkably, this approach can be easily incorporated into standard electrode preparation processes with no additional processing step. PMID- 29171939 TI - Initial flow cytometric evaluation of the Clearllab lymphoid screen. AB - INTRODUCTION: Flow cytometric immunophenotyping (FCI) is an integral part in the diagnosis and classification of hematologic malignancies. FCI results also influence therapeutic decisions and disease prognosis. ClearLLab LS is a 12 antibody 10-color cocktail provided in dry format designed as a screen for patients suspected of having hematolymphoid disease. METHODS: A blinded comparison between ClearLLab LS, (CD8-FITC, Kappa-FITC,CD4-PE, Lambda-PE, CD19 ECD, CD56-PE-Cy5.5, CD10-PE-Cy7, CD34-APC, CD5-APC-A700, CD20-APC-A750, CD3-PB, and CD45-KrO), ClearLLab Reagents (five-color, 17-antibodies) and individual Laboratory Developed Tests (LDTs), was conducted at four laboratories. Evaluation of ClearLLab LS was performed on 210 specimens, compared to the five-color ClearLLab Reagents (IVD and CE-IVD), and a subset (n = 167) to LDTs. RESULTS: ClearLLab LS showed good agreement to ClearLLab Reagents in detecting the absence (104/104) or presence (106/106) of abnormal populations. Of specimens with abnormal populations the ClearLLab LS agreed with the ClearLLab Reagent for neoplasm maturity assessment (70/70 mature and 36/36 immature). Out of 167 specimens with LDTs results, 86 contained abnormal population(s), ClearLLab LS detected 82 (95.3%) of cases. Of the 4 cases not detected by ClearLLab LS, 3 were plasma cell neoplasms and 1 was a mature T cell malignancy. Eighty-one samples with no hematological malignancy as analyzed by LDT were also negative by ClearLLab LS (100% agreement). ClearLLab LS agreed with LDTs assessment of neoplasms' maturity (55/55 mature and 27/27 immature). CONCLUSION: ClearLLab LS screening tube showed excellent agreement between ClearLLab Reagents and with LDT's. The presence of CD34 and CD10 in the tube allowed the detection of blast populations in several acute leukemias and myeloid neoplasms that were tested.

AB - Adverse drug reactions (ADR) can be broadly categorised as either on-target or off-target. On-target ADRs arise as a direct consequence of the pharmacological properties of the drug and are therefore predictable and dose-dependent. On target ADRs comprise the majority (>80%) of ADRs, relate to the drug's interaction with its known pharmacological target and are a result of a complex interplay of genetic and ecologic factors. In contrast, off-target ADRs, including immune-mediated ADRs (IM-ADRs), are due to unintended pharmacological interactions such as inadvertent ligation of host cell receptors or non pharmacological interactions mediated through an adaptive immune response. IM ADRs can be classified according to the primary immune cell involved and include B-cell-mediated (Gell-Coombs type I-III reactions) and T-cell-mediated (Gell Coombs type IV or delayed hypersensitivity) reactions. IM-ADRs mediated by T cells are associated with phenotypically distinct clinical diagnoses and can vary from a mild delayed rash to a life-threatening cutaneous, systemic or organ disease, such as Stephen Johnson syndrome/toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms and drug-induced liver disease. T-cell-mediated ADRs are strongly linked to the carriage of particular HLA risk alleles which are in the case of abacavir hypersensitivity and HLA-B*57:01 has led to translation into the clinic as a routine screening test. In this review, we will discuss the immunogenetics and pathogenesis of IM-ADRs and how HLA associations inform both pre-drug screening strategies and mechanistic understanding.

PMID- 29171941 TI - Extracorporeal cellular therapy (ELAD) in severe alcoholic hepatitis: A multinational, prospective, controlled, randomized trial. AB - Severe alcoholic hepatitis (sAH) is associated with a poor prognosis. There is no proven effective treatment for sAH, which is why early transplantation has been increasingly discussed. Hepatoblastoma-derived C3A cells express anti inflammatory proteins and growth factors and were tested in an extracorporeal cellular therapy (ELAD) study to establish their effect on survival for subjects with sAH. Adults with sAH, bilirubin >=8 mg/dL, Maddrey's discriminant function >= 32, and Model for End-Stage Liver Disease (MELD) score <= 35 were randomized to receive standard of care (SOC) only or 3-5 days of continuous ELAD treatment plus SOC. After a minimum follow-up of 91 days, overall survival (OS) was assessed by using a Kaplan-Meier survival analysis. A total of 203 subjects were enrolled (96 ELAD and 107 SOC) at 40 sites worldwide. Comparison of baseline characteristics showed no significant differences between groups and within subgroups. There was no significant difference in serious adverse events between the 2 groups. In an analysis of the intent-to-treat population, there was no difference in OS (51.0% versus 49.5%). The study failed its primary and secondary end point in a population with sAH and with a MELD ranging from 18 to 35 and no upper age limit. In the prespecified analysis of subjects with MELD < 28 (n = 120), ELAD was associated with a trend toward higher OS at 91 days (68.6% versus 53.6%; P = .08). Regression analysis identified high creatinine and international normalized ratio, but not bilirubin, as the MELD components predicting negative outcomes with ELAD. A new trial investigating a potential benefit of ELAD in younger subjects with sufficient renal function and less severe coagulopathy has been initiated. Liver Transplantation 24 380-393 2018 AASLD.

It usually manifests itself in adolescence by a hematocolpos. Hematocolpos is the vaginal retention of menstrual blood at puberty. It results clinically in painful amenorrhea and more rarely in a pelvic mass syndrome. The diagnosis is easy, it is primarily clinical. Pelvic ultrasound and nuclear magnetic resonance are the complementary examinations to be performed as a preoperative assessment and to detect any associated genito-urinary malformations. PMID- 29171946 TI - [Cardiac rehabilitation, state of the art 2017]. AB - Cardiovascular disease remains the leading cause of death in western countries. Despite advances in acute management of patients, secondary prevention remains essential and should include cardiac rehabilitation. Recent data have confirmed the interest of this management in the various conventional indications : coronary disease, valvular heart disease, heart failure and heart transplantation. New indications emerge with some benefit that should be evaluated : ventricular assistance, pulmonary hypertension, trans-catheter aortic valve implantation. However, the different rehabilitation programs proposed are still too uneven in content and duration and the number of patients participating in these programs remains low. Home based cardiac rehabilitation technologies have already shown some effectiveness and could improve some of the weaknesses of rehabilitation programs. Again protocols and tools need to be improved and standardized. The budgetary impact will also have to be studied further. PMID- 29171947 TI - [Perception by the oncologist of the parental distress in childhood cancer survivor]. AB - The aim of the study was to assess the degree of similarity between the distress expressed by parents of a child cancer survivor and the distress perceived by the oncologist. Overall, 61 parents of a child cancer survivor (between 4 and 6 years of cancer remission) were recruited in Belgian hospitals (Province of Liege). Parents filled out questionnaires about the intolerance of uncertainty (IUS), positive beliefs about worry (WW-II), parental worries about the evolution of their child's health (QIPS-R15), problem orientation (NPOQ), cognitive avoidance (CAQ), ruminations (Mini-CERTS), and anxiety/depression (HADS). Eight oncologists who having taken care of the child filled out the "OncoMed" questionnaire that examines their perception of the parental distress (e.g. anxiety, worries). Parents suffered from anxiety,worries about their child's health and showed a low level of tolerance of uncertainty. Overall, oncologists demonstrated a low perceived distress compared to the level of parental distress. The study highlights the need to detect early parents who are intolerant of uncertainty in order to offer them an efficient psychological follow-up. This study underlines finally the necessity to develop medical perception tools about the distress in order to strengthen the medical communication and the follow-up of these families.

PMID- 29171949 TI - [Multidisciplinary team meetings : experiences and difficulties of ambulatory care professionals. A qualitative study.] AB - Multidisciplinary work is gaining importance with the ageing of the population, an increase in the number of chronically ill patients, and patients' preference for homebased healthcare. Multidisciplinary team meetings (MDTMs) were designed to foster dialogue between care providers of patients with decreasing autonomy. Despite being financed by the Health Insurance, few professionals use it. This study aimed at an exploration of the professionals' reasons for this lack of MDTM. Semi-structured interviews with health and social care providers who had participated in an MDTM were analysed thematically by two researchers working independently. All of the professionals recognised the importance of MDTMs in improving support for patients and their relatives. Each person's presence at the MDTM helped participants to define their scope of action, to become acquainted with one another, and to coordinate their work. Administrative and logistical limitations were cited as obstacles, as was the absence of a multidisciplinary working culture. MDTMs place the patient at the forefront, and allow professionals to meet and agree on a treatment plan. A range of different working practices and cultures challenges the method. PMID- 29171950 TI - [Evolocumab (Repatha(r)) : a human monoclonal antibody against PCSK9 protein as potent cholesterol-lowering therapy]. AB - Evolocumab is a fully human monoclonal antibody (mAb) targeting ProProtein Convertase Subtilisin/Kexin 9 (PCSK9). PCSK9 is a circulating enzyme secreted by the liver and plays a key role in the LDL-Receptors (LDL-R) turnover. Binding of PCSK9 on the extracellular part of LDL-R is responsible for its degradation in the lysosome instead of its recycling to the cell surface, thereby producing a reduction in the number of LDL-R on the cell surface, a decreased LDL-C uptake and increased levels of LDL-C. Inhibiting PCSK9 is a new way to markedly reduce LDL-C. The development of mAbs that bind the extracellular PCSK9 and prevent its interaction with LDL-R is the most advanced and tested approach to PCSK9 inhibition to date. The clinical efficacy and safety of evolocumab have been studied in a number of controlled trials versus placebo or versus active comparator (ezetimibe) during 12 to 76 weeks. Added on statin, evolocumab reduced LDL-C up to 50 to 60 % from baseline. Evolocumab also reduced LCL-C in monotherapy in statin-intolerant patients. Evolocumab also significally reduced total cholesterol, non-HDL cholesterol, apoprotein B and lipoprotein(a). Safety and tolerance were good. Evolocumab is commercialized under the trade name Repatha(r) and administrated subcutaneously at the dose of 140 mg every 2 weeks or 420 mg once per month. Repatha(r) is approved in Belgium, with conditions, for the treatment of hypercholesterolemia in patients with heterozygous (HFe) and homozygous (HFo) familial hypercholesterolemia.

PMID- 29171952 TI - Dynamics of Radical Ions of Hydroxyhexafluoroisopropyl-Substituted Benzenes. AB - Fluorination of resist materials is an effective method used to enhance the energy deposition of extreme ultraviolet (EUV) light in the fabrication of next generation semiconductor devices. The dynamics of radical ions are important to understand when considering the radiation-chemistry of the resist materials using EUV and electron beam lithography. Here, the dynamics of the radical anions and cations of benzenes with one or two 2-hydroxyhexafluoroisopropyl groups (HFABs) were studied using radiolysis techniques. The formation of dimer radical cations was observed only in the monosubstituted benzene solutions of 1,2-dichloroethane. If the compound contained more than two substituents, it was found to hinder the necessary pi-pi overlapping. Pulse radiolysis of HFABs in tetrahydrofuran showed a characteristic spectral shift of the radical anion within the region of several hundred nanoseconds. From the results of low-temperature spectroscopy and density functional calculations, it is suggested that excess electrons of the 2 hydroxyhexafluoroisopropyl group of the radical anions cause dissociation into neutral radicals. PMID- 29171953 TI - Topologically Micropatterned Collagen and Poly(epsilon-caprolactone) Struts Fabricated Using the Poly(vinyl alcohol) Fibrillation/Leaching Process To Develop Efficiently Engineered Skeletal Muscle Tissue. AB - Optimally designed three-dimensional (3D) biomedical scaffolds for skeletal muscle tissue regeneration pose significant research challenges. Currently, most studies on scaffolds focus on the two-dimensional (2D) surface structures that are patterned in the micro-/nanoscales with various repeating sizes and shapes to induce the alignment of myoblasts and myotube formation. The 2D patterned surface clearly provides effective analytical results of pattern size and shape of the myoblast alignment and differentiation. However, it is inconvenient in terms of the direct application for clinical usage due to the limited thickness and 3D shapeability. Hence, the present study suggests an innovative hydrogel or synthetic structure that consists of uniaxially surface-patterned cylindrical struts for skeleton muscle regeneration. The alignment of the pattern on the hydrogel (collagen) and poly(epsilon-caprolactone) struts was attained with the fibrillation of poly(vinyl alcohol) and the leaching process. Various cell culture results indicate that the C2C12 cells on the micropatterned collagen structure were fully aligned, and that a significantly high level of myotube formation was achieved when compared to the collagen structures that were not treated with the micropatterning process. PMID- 29171954 TI - Mitochondrial-Targeting Lonidamine-Doxorubicin Nanoparticles for Synergistic Chemotherapy to Conquer Drug Resistance. AB - Lonidamine (LND) can act on mitochondria and inhibit energy metabolism in cancer cells and therefore has been used together with chemotherapy drugs for synergistically enhanced therapeutic efficacy. However, its use is hindered by the poor solubility and slow diffusion in the cytoplasm. To address these problems, we designed and prepared aqueous dispersible nanoparticles (NPs) containing integrated components including triphenylphosphine (TPP) to target the mitochondria of cells and LND and doxorubicin (DOX) for synergistic cancer treatment and conquering drug resistance. This design allows the NPs to concentrate in the mitochondria of cells, solve the low solubility of LND, and contain very high load of LND and DOX in comparison with previously reported drug delivery systems based on various carrier nanomaterials. Detailed mechanism studies reveal that TPP-LND-DOX NPs could induce significant reactive oxygen species production, mitochondrial membrane potential decrease, and mitochondrial apoptosis pathway, thereby leading to great cytotoxicity in cancer cells. In vivo anticancer activities indicate that TPP-LND-DOX NPs exhibit the highest efficacy in tumor inhibition among all tested groups and show high effectiveness in drug resistant model. This work demonstrates the potential use of our TPP-LND-DOX NPs to jointly promote the mitochondria apoptosis pathway and contribute to conquer drug resistance in cancer therapy. PMID- 29171955 TI - Energetics of van der Waals Adsorption on the Metal-Organic Framework NU-1000 with Zr6-oxo, Hydroxo, and Aqua Nodes. AB - We report measurements of adsorption isotherms and the determination of the isosteric heats of adsorption of several small gases (H2, D2, Ne, N2, CO, CH4, C2H6, Ar, Kr, and Xe) on the metal-organic framework (MOF) NU-1000, which is one of the most thermally stable MOFs. It has transition-metal nodes of formula Zr6(MU3-OH)4(MU3-O)4(OH)4(OH2)4 that resemble hydrated ZrO2 clusters and can serve as catalysts or catalyst supports. The linkers in this MOF are pyrenes linked to the nodes via the carboxylate groups of benzoates. The broad range of adsorbates studied here allows us to compare trends both with adsorption on other surfaces and with density functional calculations also presented here. The experimental isotherms indicate similar filling of the MOF surface by the different gases, starting with strong adsorption sites near the Zr atoms, a result corroborated by the density functional calculations. This adsorption is followed by the filling of other adsorption sites on the nodes and organic framework. Capillary condensation occurs in wide pores after completion of a monolayer. The total amount adsorbed for all the gases is the equivalent of two complete monolayers. The experimental isosteric heats of adsorption are nearly proportional to the atom-atom (or molecule-molecule) Lennard-Jones well-depth parameters of the adsorbates but ~13-fold larger. The density functional calculations show a similar trend but with much more scatter and heats that are usually greater (by 30%, on average). PMID- 29171956 TI - The Montreal Cognitive Assessment (MoCA) in a population-based sample of Turkish migrants living in Germany. AB - OBJECTIVES: Data on cognitive testing in migrants in Germany are scarce. We aimed to evaluate the Montreal Cognitive Assessment (MoCA) in Turkish migrants in Berlin and its association with demographics and health-related variables. METHOD: For this cross-sectional study, a random sample of persons with Turkish names was drawn from the registration-office. Cognitive function was assessed using the MoCA; 0 = worst, 30 = best total score. Multivariable linear regression models were calculated to determine associated factors with the total MoCA-score. RESULTS: In our analyses we included 282 participants (50% female), mean age 42.3 +/- 11.9 years (mean +/- standard deviation (SD)). The mean +/- SD MoCA score was 23.3 +/- 4.3. In the multivariable analysis, higher education (beta = 2.68; p < 0.001), and chosing the German version of the MoCA (beta = -1.13; p = 0.026), were associated with higher MoCA-scores, whereas higher age (beta = -0.08; p = 0.002) was associated with lower MoCA scores. CONCLUSION: In our study, a higher educational level, lower age, and German as the preferred test language (as compared to Turkish) were positively associated with the cognitive performance of Berliners with Turkish roots. To examine neurocognitive health of migrants, longitudinal population-based and clinical cohort studies that specifically compare migrants and their descendants with the original population of their home countries are required. PMID- 29171957 TI - Carotid artery longitudinal wall motion: regulatory factors and implications for arterial health. AB - The carotid artery wall moves longitudinally along the length of the vessel, although little is known about what causes this motion, or what health information it represents. The overarching purpose of this dissertation was to investigate the regulation of carotid artery longitudinal wall motion (CALM) in humans, as well as how CALM can be used to infer information about arterial health. Through observational and experimental designs, we tested evidence for a structural ventricular-vascular coupling effect, which postulates that systolic anterograde CALM is influenced by the forward blood shear rate while systolic retrograde CALM is influenced by left ventricular rotation, although the data suggest a moderate influence of left ventricular rotation, and minimal influence of shear rate. In cross-sectional analyses, we demonstrated that diastolic CALM variables are better related to age and health status compared with systolic CALM displacement and that this relationship was independent of traditional measures of arterial stiffness. These experimental and observational results directed the use of diastolic CALM as a potential indicator of arterial health in subsequent studies, owing to the relative independence from systolic events. While there was no effect of 12 weeks of exercise training in healthy men on diastolic CALM variables, we observed increased systolic retrograde CALM and diastolic CALM acceleration in men with a history of resistance exercise training compared with sedentary men, suggesting an effect of habitual exercise training. Our novel findings suggest that CALM is regulated by a complex system, in part related to both arterial wall structure and ventricular-vascular coupling, and may have clinical value in complimenting measures of traditional arterial stiffness in humans. Future studies should examine whether local changes to arterial wall structure or indirect changes in regulatory control dictate differences in CALM with aging and with chronic exercise training, before integrating CALM into routine measurement of arterial health. PMID- 29171958 TI - Fecal incontinence as a moderator between dietary intake and depressive symptoms among a sample of older adults obtained from the National Health and Nutrition Examination Survey (NHANES). AB - OBJECTIVES: Many studies have established a relationship between diet and mental health, as well as the importance of bowel health. Further, with increased evidence of a gut-brain bidirectional relationship, an indication of dysbiosis as a potential moderator between diet and depression may be a viable target for future interventions. The current study investigated the relationship between diet and depressive symptoms (DS) among older adults, as well as gender, and whether a symptom of dysbiosis, fecal incontinence severity (FIS), moderated this relationship. METHOD: Using moderated regressions, we examined whether FIS moderates the relationship between diet and DS while controlling for covariates in the overall sample (N = 1918), as well as among the male (n = 841) and female sample (n = 1077). The dietary variables were reduced using a factor analysis. RESULTS: Results indicated significant moderating effects of FIS between Component 4 and polyunsaturated fatty acids (PFA) in the overall sample. Component 4, protein, carbohydrates, and alcohol were significant in males only while PFA only in females. Further analysis of protein/carbohydrate ratio groups indicated significant differences within males. Higher scores of FIS were related to higher DS and less consumption of Component 4 nutrients, PFA, and protein. Males that consumed higher protein and carbohydrates resulted in lower DS with increased FIS. CONCLUSION: Outcomes from the current study provide further evidence of the importance of healthy bowel function and the potential of modifying the diet to improve DS in older adults. PMID- 29171959 TI - The influence of social support and perceived stress on response time inconsistency. AB - OBJECTIVES: Lack of social support and high levels of stress represent potentially modifiable risk factors for cognitive aging. In this study we examined the relationships between these two risk factors and response time inconsistency (RTI), or trial-to-trial variability in choice response time tasks. RTI is an early indicator of declining cognitive health, and examining the influence of modifiable psychosocial risk factors on RTI is important for understanding and promoting cognitive health during adulthood and old age. METHODS: Using data from a community sample study (n = 317; Mage = 49, range = 19 83), we examined the effects of social support, including size of network and satisfaction with support, global perceived stress, and their interactions on RTI. RESULTS: Neither size of network nor satisfaction with support was associated with RTI independent of perceived stress. Stress was positively associated with increased RTI on all tasks, independent of social support. Perceived stress did not interact with either dimension of social support to predict RTI, and perceived stress effects were invariant across age and sex. CONCLUSION: Perceived stress, but not social support, may be a unique and modifiable risk factor for normal and pathological cognitive aging. Discussion focuses on the importance of perceived stress and its impact on RTI in supporting cognitive health in adulthood and old age. PMID- 29171960 TI - Longitudinal trajectories of subjective care stressors: the role of personal, dyadic, and family resources. AB - OBJECTIVES: Stressors are critical to the caregiver stress process, yet little work has examined resources that contribute to longitudinal changes in subjective stressors. The present study examines a variety of factors that contribute to changes in subjective stressors across time. METHOD: Dementia caregivers (N = 153) completed an in-person interview and eight daily telephone interviews at baseline, and follow up interviews at 6 and 12 months. Growth curve analyses examine how care- and non-care stressors, respite, dyadic relationship quality, family support/conflict and care transitions (e.g. nursing home placement) are associated with changes in role overload and role captivity across 12 months. RESULTS: Caregivers who transitioned out of their role had higher overload and captivity at baseline. Among caregivers who transitioned out of caregiving, higher captivity at baseline was associated with declines in captivity and overload; more non-care stressors at baseline was linked to increased captivity and greater overload across time. Adult day service use and family support were associated with lesser captivity over time; taking more breaks from caregiving was linked to lower overload. Higher dyadic relationship quality was associated with lower captivity and overload. CONCLUSION: Findings contribute to caregiver intervention efforts by highlighting important resources associated with subjective stressors across time. PMID- 29171961 TI - Social impact of menstrual problems among adolescent school girls in rural Tamil Nadu. AB - Background Adolescence is a period of physiological, psychological and social transition between childhood and adulthood and is characterized by the onset of menstruation in girls. A adolescent girls are naive about menstruation and they take time to adapt to these changes both socially and psychologically. This study was carried out to assess the psychosocial impact of menstrual problems among schoolgoing adolescent girls. Methods This study is a cross-sectional study carried out in 350 schoolgoing adolescent girls in the year 2012 in the Thiruvallur district of Tamil Nadu. Girls who attained menarche 1 year prior to the data collection were included in the study. Data regarding background characteristics and psychosocial impact of menstrual problems were collected. Data was analyzed using SPSS ver. 15 software. The chi2-test was carried out to assess the statistical significance at the 95% level of significance. Results The mean age of the participants was 14.7 years. In this study, 87.7% of the girls had at least one menstrual problem. Among these, 78.5% could not attend school during menstruation, 51.1% were unable to perform household/sports activities (p < 0.001). It was observed that dysmenorrhea and menorrhagia were at increased risk of absenting the girls from school (p < 0.05). Conclusion The key to a sound adolescent health programme is a holistic approach which also focuses on the psychological and social domain of health. This could be achieved by involving all the stakeholders like parents, teachers, etc. to work as a team. It is also essential to develop adolescent friendly health services at the grass root level. PMID- 29171962 TI - Maternal demographic factors associated with emergency caesarean section for non reassuring foetal status. AB - OBJECTIVES: This study aimed to determine maternal and obstetric factors associated with emergency caesarean section (CS) for non-reassuring foetal status (NRFS). MATERIALS AND METHODS: This was a retrospective analysis of term singleton births between January 2007 and December 2015 at the Mater Mother's Hospital in Brisbane. The study group comprised all cases of emergency CS for NRFS, and the control cohort comprised all other births meeting the inclusion criteria but excluding those in the study cohort. RESULTS: Over the study period, there were 74,177 births fulfilling the inclusion criteria. The overall rate of emergency CS for NRFS was 4.2% (3132/74,177). Multivariate analysis showed that being overweight and obese, Indian and "other" ethnicity, artificial reproductive techniques, smoking, induction of labour and gestation at 39-42 weeks were associated with an increased risk, whereas being underweight, female sex, hypertension and birth without labour conferred a lower risk. CONCLUSION: Many maternal and obstetric factors were associated with emergency CS for NRFS and influenced adverse perinatal outcomes. Recognition of these risk factors could help risk stratify women prior to labour. PMID- 29171963 TI - Indium selenide monolayer: strain-enhanced optoelectronic response and dielectric environment-tunable 2D exciton features. AB - Electronic and optical performances of the beta-InSe monolayer (ML) are considerably boosted by tuning the corresponding band energies through lattice in plane compressive strain engineering. First principles calculations show an indirect-direct gap transition with a large bandgap size. The crossover is due to different responses of the near-gap state energies with respect to strain. This is explained by the variation of In-Se bond length, the bond nature of near-band edge electronic orbital and of the momentum angular contribution versus in-plane compressive strain. The effective masses of charge carriers are also found to be highly modulated and significantly light at the indirect-direct-gap transition. The tuned optical response of the resulting direct-gap ML beta-InSe is evaluated versus applied energy to infer the allowed optical transitions, dielectric constants, semiconductor-metal behavior and refractive index. The environmental dielectric engineering of exciton behavior of the resulting direct-gap ML beta InSe is handled within the effective mass Wannier-Mott model and is expected to be important. Our results highlight the increase of binding energy and red shifted exciton energy with decreasing screening substrates, resulting in a stable exciton at room temperature. The intensity and energy of the ground-state exciton emission are expected to be strongly influenced under substrate screening effect. According to our findings, the direct-gap ML beta-InSe assures tremendous 2D optoelectronic and nanoelectronic merits that could overcome several limitations of unstrained ML beta-InSe.

AB - PURPOSE: We evaluated the relation between first site of recurrence of early breast cancer and disease profile at presentation and reported survival results, suggesting a personalized diagnostic imaging guidance during follow up. METHODS: Among 1400 early breast cancer treated from 2000 to 2010, 324 relapses were divided into 4 groups according to first site: A-locoregional, B-bone, C-Brain and D-visceral. We analyzed redictive factors of each group compared to a control group of 100 non relapsing patients and the remaining groups matched. RESULTS: In group A, patients were more likely to have histological tumor size above >2 cm, grade 1-2, HR positive and 0-3 involved lymph nodes. In group B, patients had more commonly grade 2-3, 1-3 positive lymph nodes and HR positive tumors. In group C, patients were more frequently young, with large tumor size, grade3, positive lymph nodes and HER2 positive tumors. In group D, patients were more likely to have tumors>2 cm in size, with nodal involvement, grade 3, HR negative and HER2 positive tumors. Annual recurrence rate in group A, was stable ranging between 15%-18%, within the first 3 years and peaked at 19.4% in the interval [1 2]year in group B. Median survival was 46 months in group A, 43 months in group B, with no significant difference. CONCLUSION: Outcome of loco-regional and bone relapses was good, suggesting that both systematic mammography and bone-scan/CT scan for high risk patients (N+, gradeIII) during the first 2-3 years may represent a tailored relevant follow-up protocol for breast cancer patients.

AB - The effect of myocardial infarction on the global functioning of the heart is well known. Less is understood regarding the effect of LV fibrotic infarction on the cardiac mechanics of the septal wall. To determine this unknown, the stress and strain of septal wall on the healthy and infarcted rat heart model is measured by using finite element models of rat heart geometries. The main objective of this study was to utilized computational methods to study the effect of LV free wall fibrotic infarction on the healthy septal wall. Three-dimensional biventricular rat heart geometries were developed from cardiac magnetic resonance images of a healthy heart and a heart with left ventricular (LV) fibrotic infarction after infarct induction. From these geometries, FE models were established. Three-dimensional biventricular rat heart geometries developed from cardiac magnetic resonance images were used in creating FE models of healthy and infarcted rat hearts. The average radial strain percentage change of the healthy septal wall on the epicardium, mid-wall and endocardium was 61%, 52% and 14% higher than the infarcted septal wall, respectively. It was concluded that the fibrotic infarction has a potential cause the malfunction of the heart due to high myocardial stress and strain that the septal wall experiences.

PMID- 29171967 TI - Surface characteristics of three commercially available grafts and adhesion of stem cells to these grafts. AB - BACKGROUND: Reconstruction of bone defects is often performed using bone autografts. However, limitations associated with the use of autografts led to the use of bone substitute materials. OBJECTIVES: The purpose of this study was to compare the surface characteristics of three commercially available grafts namely allografts, xenografts and alloplasts. METHODS: This in vitro study was conducted on beta-tricalcium phosphate (beta-TCP) alloplast, a mixture of demineralized bone matrix and mineralized bone allograft (DBM&MBA) and natural bovine bone mineral (NBBM) xenograft. Presence of apatite groups on the surface of samples was assessed by X-ray diffraction (XRD) while the presence of functional groups was evaluated using Fourier transform infrared spectroscopy (FTIR). Also, dental pulp stem cells (DPSCs) were cultured on the surface of samples and their adhesion was evaluated under a scanning electron microscope (SEM). RESULTS: The FTIR showed a relatively similar pattern for NBBM and TCP samples and a different pattern in DBM&MBA. The results of XRD analysis also showed similarities between NBBM and TCP with sharper peaks than the DBM&MBA sample. The SEM micrographs showed that at 24 hours, no cell was detectable on the surface of NBBM sample; whereas, elongated cells were noted on the surface of TCP and DBM&MBA samples. CONCLUSIONS: The patterns of beta-TCP and NBBM samples in XRD and FTIR spectroscopy showed high resemblance but they had different behaviors with respect to cell adhesion.

AB - OBJECTIVE: To investigate the effects of Uygur sand therapy on the mechanical properties of the femur bone of osteoarthritic rabbits. METHODS: Sixteen rabbits were injected with papain in the right posterior femoral articular cavity on the first, fourth and seventh day to establish the osteoarthritis (OA) rabbit model. Animals were divided into the experimental group and control group (8 rabbits each). The experimental group was treated with sand therapy, and the control group received no sand therapy treatment. Computed tomography (CT) scanning was used to collect the data of the femur before modeling, after modeling and 14 and 28 days after sand treatment. A 3D model of the femur was generated with the MIMIC software the bone layer was divided according to the different gray values and the change of the bone volume was analyzed. The body mesh is divided, and the material properties are given, then the three-point bending simulation is performed in Ansys. Additionally, the three-point bending test was performed on all the rabbits' femur to obtain the deflection and maximum stress values. And the effects of the sand treatment on the volume and mechanical properties of the bone were analyzed. Finally, the simulation results are compared with the experimental results, and the effects of sand treatment on the volume and mechanical properties of the bone are analyzed. RESULTS: (1) there is a tendency in the control group to convert the hard bone into dense bone and soft bone, while in the experimental group, the soft bone is converted into dense bone and hard bone obviously; (2) the morphological parameters of the experimental group are lower than those of the control group, whereas the maximum load, maximum normal stress, maximum shear stress of the experimental group are higher than those of the control group. (3) The mechanical test of three-point bending test was carried out using the three dimensional finite element model of rabbit femur. CONCLUSION: The sand therapy has positive effects on the volume distribution of bone layer and the mechanical properties of the femur of adult osteoarthritic rabbits.

AB - BACKGROUND: The clinical magnetic resonance imaging (MRI) images may get corrupted due to the presence of the mixture of different types of noises such as Rician, Gaussian, impulse, etc. Most of the available filtering algorithms are noise specific, linear, and non-adaptive. OBJECTIVE: There is a need to develop a nonlinear adaptive filter that adapts itself according to the requirement and effectively applied for suppression of mixed noise from different MRI images. METHODS: In view of this, a novel nonlinear neural network based adaptive filter i.e. functional link artificial neural network (FLANN) whose weights are trained by a recently developed derivative free meta-heuristic technique i.e. teaching learning based optimization (TLBO) is proposed and implemented. RESULTS: The performance of the proposed filter is compared with five other adaptive filters and analyzed by considering quantitative metrics and evaluating the nonparametric statistical test. The convergence curve and computational time are also included for investigating the efficiency of the proposed as well as competitive filters. CONCLUSION: The simulation outcomes of proposed filter outperform the other adaptive filters. The proposed filter can be hybridized with other evolutionary technique and utilized for removing different noise and artifacts from others medical images more competently. PMID- 29171970 TI - Bone regeneration from human mesenchymal stem cells on porous hydroxyapatite-PLGA collagen bioactive polymer scaffolds. AB - We have developed a novel multicomponent nano-hydroxyapatite-poly(D,L-lactide-co glycolide)-collagen biomaterial (nHAP-PLGA-collagen) with mechanical properties similar to human cancellous bone. To demonstrate the bone forming capacity of nHAP-PLGA-collagen prior to in vivo experiments, nHAP-PLGA-collagen films and 3D porous scaffolds were seeded with human mesenchymal stem cells (hMSCs) to characterize cell proliferation and osteogenic differentiation. Over 21 days hMSCs seeded on 2D nHAP-PLGA-collagen films proliferate, form nodules, deposit mineral and express high alkaline phosphatase activity (ALP) indicating commitment of hMSCs towards osteogenic lineage. When seeded in 3D scaffolds, hMSCs migrate throughout the connected porous network of the nHAP-PLGA-collagen scaffold and proliferate to fill the scaffold voids. Over 35 days, cells express ALP, osteocalcin and deposit minerals with kinetics similar to osteogenesis in vivo. Adipogenic or chondrogenic differentiation is not detected in 3D constructs, indicating that in an osteogenic environment the presence of bone ECM specific molecules in nHAP-PLGA-collagen scaffolds support homogeneous bone tissue development. This ability of nHAP-PLGA-collagen matrices to provide biochemical stimulation to support osteogenesis from stem cells along with its high mechanical strength suggests that nHAP-PLGA-collagen is a suitable biomaterial for bone regeneration. This platform technology of covalently attaching ECM proteins and molecules with synthetic and natural polymers to adjust material properties and biochemical signaling has a potential for a wider range of applications in tissue engineering and regenerative medicine. PMID- 29171971 TI - A method for systematically evaluating the hemostatic ability of hydrogels in vitro. AB - The bursting strength is a key parameter to assess hemostatic ability of tissue sealants. It is associated to mechanical property of the materials, the binding strength of the materials to the tissues as well as the applied conditions of the materials, such as temperature and wound size. Few works have systematically investigated the relationship of the hemostatic ability of hydrogels with the factors listed above. This study introduced a method to systematically investigate the effect of the thickness, covered area and components of hydrogels, and the applied conditions on the bursting strength of hydrogels. The gelatin hydrogel and fibrin glue were used in this study. The method quantitatively investigated the effect of material properties and applied conditions on the bursting strength of materials. It also suggested a minimum dosage of tissue sealant used in both animal study and clinical practice. This study proved that the method we proposed is reliable to assess the bursting strength of materials for the hemostatic application.

Moreover, NaOH and radioactive methods were the most reliable methods among the direct methods. PMID- 29171973 TI - Biocompatibility evaluation and corrosion resistance of tungsten added Co-30Cr 4Mo-1Ni alloy. AB - Biomaterials are continuously being developed to overcome the drawbacks of existing materials and provide improved function in artificial organs. Currently Co-Cr based alloys are used in many medical applications such as hip and knee implants which still require modification to better perform. In this article, therefore, the influence of tungsten allying element on electrochemical corrosion resistance and biocompatibility behaviour of a recently developed Co-30Cr-4Mo-1Ni alloy composition were investigated. The tungsten modified alloys were prepared by using a high temperature vertical vacuum casting technique at five different weight percentages (0-4wt.% tungsten). The electrochemical corrosion behaviour of all the samples under NaCl solution was studied by using potentiodynamic scan method. The corrosion characteristics were investigated in terms of corrosion potential (Ecorr) and corrosion current density (Icorr). From the results of the analysis, it was observed that out of all samples, an alloy with 2wt.% of tungsten in composition (i.e. Co-30Cr-4Mo-1Ni-2W) exhibited better corrosion resistance. Furthermore, histopathological evaluations in subcutaneous tissue were performed in rats according to the standard ISO 10993 to examine the biocompatibility of the prepared samples. The results showed no evidence of inflammatory cell migration, no epidermal necrosis, no vacuolar degeneration of basal cell, no adnexal atrophy and vesicle formation of any samples. The obtained findings indicate that Co-30Cr-4Mo-1Ni-2W can be used in biomedical applications including femoral component of hip and knee implants.

PMID- 29171974 TI - Co-existence effect of tricalcium phosphate and bioactive glass on biological and biodegradation characteristic of Poly L-Lactic Acid (PLLA) in trinary composite scaffold form. AB - The purpose of this study is to analyze the co-existence effect of 30 wt.% TCP-BG phases on degradation and precipitation behaviors of PLLA based composite scaffold in biological media. First, phase separation method was used to synthesize of the pure PLLA and the trinary composite scaffolds, and second they were immersed in SBF solution for 45 days. Subsequently, the degradation and precipitation characteristic were investigated by analyzing of pH value and weight changes of the immersed samples, the ability of biological products formation and the change of relative molecular weight of PLLA matrix as function of the degradation time. Finally, the experimental data of relative molecular weight change were verified by Han and Pan model and comparisons were made between them. Results have represented precipitation of huge amount of carbonate apatite on surface of the composite scaffold, and also the acidity of SBF media changes moderately which is prove better bioactivity properties compare to the pure PLLA scaffold. The results of comparison with the model point to quiet good agreement between them in early stage of degradation. So, the consequences suggest that the TCP-BG/PLLA composite scaffold have great potential to be applied in bone replacements or repairs. PMID- 29171976 TI - Right versus left side bridge static endurance ability among healthy collegiate students at Taibah University. AB - BACKGROUND: Spinal muscles endurance is fundamental for providing adequate trunk stability. OBJECTIVE: The purpose of this study was to compare the side bridge static endurance ability of the right versus left side. METHODS: Forty right hand dominant students, aged between 18 and 25 years, were recruited from Taibah University. Every participant had to lie down on his side and bear trunk weight on the arm with shoulder abducted to 90? and elbow flexed to 90?. Every participant had to lift off his trunk of the supporting surface, keeping the trunk straight in neutral position, breathing normally and holding on that position as long as tolerated. RESULTS: A paired sample t test was calculated. The mean score, in seconds, for right side bridge was 41.6 (SD = 30.08), and for left side bridge was 38.00 (SD = 26.93). No significant difference was found between right and left side bridge endurance ability [t (39) = 1.67, p> 0.05]. Pearson correlation showed high positive correlation [r (38) = 0.89, p< 0.001]. CONCLUSIONS: Among healthy participants, clinicians should expect very close endurance profile for the musculature of the two sides of trunk. Clinicians should equally train both sides of trunk muscles stabilizers in order to enhance tolerance. PMID- 29171977 TI - Ultrasonographic measurements of the metacarpophalangeal and talar cartilage thicknesses: A reliability study in healthy subjects. AB - BACKGROUND: Assessment of the joint cartilage using ultrasound imaging is important. OBJECTIVE: Our aim was to investigate the reliabilities of ultrasonographic measurements for talus dome (TCT) and metacarpal cartilage thicknesses (MCT). METHODS: Twenty healthy volunteers were recruited in the study. Every day, five physiatrists measured eight joint cartilage thicknesses. They repeated all the measurements in five consecutive days. RESULTS: Intra observer intraclass correlation coefficient (ICC) values were "excellent" for all MCTs, except for the 3rd left MCT on the 1st day, 4th left MCT on the 1st day and 4th right MCT on the 3rd day which were "good". They were "excellent" for the TCT measurements, except for the left side on the 3rd day and the right side on the 4th day which were "good". Inter-observer ICC values pertaining to the 2nd MCT measurements were "excellent" for all sonographers. Third and 4th MCT measurements (at least one side) were "excellent" for four and three sonographers, respectively. On the other hand, while TCT measurements were "excellent" for 4 sonographers. CONCLUSIONS: Our results have shown that sonographic measurements of MCT and TCT have good to excellent reliabilities in healthy adults. These findings support the use of ultrasound for cartilage assessment in various diseases. PMID- 29171978 TI - Comparison between zero-profile spacer and plate with cage in the treatment of single level cervical spondylosis. AB - BACKGROUND: Retrospective study of 68 patients of symptomatic cervical spondylosis who were treated by anterior cervical discectomy and fusion (ACDF). OBJECTIVE: The purpose of this study was to compare the clinical and radiological outcomes of patients with single level cervical spondylosis using either zero profile spacer (group A) or anterior cervical plate and cage (group B). METHODS: Clinical and radiological data of 68 patients undergoing ACDF from C3-C7 were collected retrospectively. There were 35 patients with a mean age of 54.05 years who received treatment by zero-profile implant. A total of 33 patients with a mean age of 52.09 years underwent fusion by traditional plate with cage. Group A and group B were followed up for an average of 23.68 months and 24.39 months, respectively. Age, blood loss, and operation time were assessed. The clinical outcomes were evaluated by JOA and VAS score before and after surgery. In addition, incidence of dysphagia was recorded. The Cobb angle (from C2 to C7) change was measured on the lateral cervical spine radiographs. RESULTS: There was no significant difference in terms of operation time and blood loss between two groups. The postoperative JOA significantly increased and the VAS decreased correspondently in both groups. The postoperative Cobb angle increased and showed statistical difference compared with preoperative Cobb angle in both groups. There was no significant difference between group A and group B in achieving clinical symptoms and radiograph improvement according to postoperative JOA, VAS and Cobb angle comparison. The incidence of postoperative dysphagia was lower in the group A than group B. CONCLUSIONS: Our study suggests that the application of zero-p spacer can achieve similar clinical and radiological improvement compared with traditional plate and cage. Meanwhile, zero-p is superior to plate and cage with a lower incidence of postoperative dysphagia. PMID- 29171979 TI - Influence of a dynamic seating habit on lumbar motor control in schoolchildren. AB - BACKGROUND: Adequate motor control is considered important for spinal stability and the prevention of low back pain in adulthood and in childhood. OBJECTIVE: Given that the sitting position can affect proprioception, this study aimed to evaluate the influence of using at school a triangular and dynamic cushion on schoolchildren's trunk motor control. METHODS: Thirty 8-year-old schoolchildren were randomized into a control group (n= 15) and a "cushion group" (n= 15), in which the children used the cushion for one year and a half. At the end of this period, a 3D-analysis was used to assess lumbar spine proprioception by means of a trunk repositioning task performed blindfolded in a seated position in two conditions (on a stable and on an unstable surface). RESULTS: The schoolchildren in the cushion group performed better at the trunk repositioning task (p= 0.02) and hold their lumbar lordosis (p= 0.03) better than the control children, in both conditions (stable and unstable). CONCLUSIONS: This preliminary study suggests that daily use of a triangular dynamic cushion has a beneficial impact on children's lumbar proprioception. Further studies are needed to confirm these results and investigate the effectiveness of its use to prevent low back pain in adulthood. PMID- 29171980 TI - Effectiveness of Neuro-Developmental Treatment (Bobath Concept) on postural control and balance in Cerebral Palsied children. AB - BACKGROUND AND OBJECTIVE: The aim of this study was to show the effects of an 8 week Neurodevelopmental Treatment based posture and balance training on postural control and balance in diparetic and hemiparetic Cerebral Palsied children (CPC). METHODS: Fifteen CPC (aged 5-15 yrs) were recruited from Denizli Yagmur Cocuklari Rehabilitation Centre. Gross Motor Function Classification System, Gross Motor Function Measure, 1-Min Walking Test, Modified Timed Up and Go Test, Paediatric Balance Scale, Functional Independence Measure for Children and Seated Postural Control Measure were used for assessment before and after treatment.

RESULTS: After the treatment program, all participants showed statistically significant improvements in terms of gross motor function (p< 0.05). They also showed statistically significant improvements about balance abilities and independence in terms of daily living activities (p< 0.05). Seated Postural Control Measure scores increased after the treatment program (p< 0.05). CONCLUSIONS: The results of this study indicate that an 8-week Neurodevelopmental Treatment based posture and balance training is an effective approach in order to improve functional motor level and functional independency by improving postural control and balance in diparetic and hemiparetic CPC. PMID- 29171981 TI - A comparison of occupational groups using different working postures in terms of their low back and neck health status. AB - OBJECTIVE: To compare how disability, fear of movement, psychosocial status and quality of life are affected in terms of low back-neck health status in three occupational groups using different work postures. METHOD: Three hundred thirty nine individuals participated in this study from the following three different occupational groups: group A, where the individuals worked in a prolonged sitting position (secretaries), group B, where the individuals performed dynamic activities in a standing position (cleaning workers) and group C, where the individuals worked in a prolonged standing position (private security officers). The participants were evaluated by Million Visual Analog Scale, Neck Disability Index, Oswestry Disability Index, Nottingham Health Profile, Hospital Anxiety and Depression Scale and Tampa Kinesiophobia Scale. RESULTS: It was found that disability, emotional status and the quality of life were minimally affected, but kinesiophobia was increased in all of the occupational groups. In the group C, low back pain disability, quality of life and fear of movement were more affected than the other groups (p< 0.05). CONCLUSION: For the occupational groups with long working years, the presence of kinesiophobia should be considered and cognitive-behavioural treatment methods should be recommended. In cleaning workers, low back pain is an important risk factor. Therefore, its awareness should be increased, and preventive programmes should be offered. PMID- 29171982 TI - Morphofunctional muscle changes influence on foot stability in multiple sclerosis during gait prediction: The rehabilitation potential. AB - BACKGROUND: Multiple sclerosis patients may suffer muscle changes that involve gait disorders of the kinetic and kinematic parameters also their gait may be clinically symmetrical or asymmetrical. OBJECTIVE: The aim of this study is to analyze how the muscle change, could affect the biomechanical parameters of foot stability during the gait, by disturb the motor control. METHODS: The study group consisted of 13 patients diagnosed with multiple sclerosis, presenting clinically detectable abnormal gait. The biomechanical evaluation included the foot axes and angles -external and internal rotation; the foot angle deviation from the gait direction; the subtalar angle. RESULTS: The values of the foot angle were between -10.74? to 26.38? for the left foot and between -11.16? to 30.04? for the right foot. The foot axis angle is the axis of the foot in relation to the gait direction, and the subtalar angle is in relation to the vertical axis of the foot. The rotation of the right foot into pronation during the initial contact phase was followed by supination in the semi-support phase, to return to the neutral position during the propulsion phase, which meant being in free zone of minimal risk. CONCLUSIONS: Biomechanical analysis of the foot angle and of subtalar angle in the patients with multiple sclerosis allows us to objectify the existence of a right-left asymmetry, the behavior ankle-foot during the gait. At the same time this evolution is closely correlated with the contact surface that tends to increase, which means involving the reflex mechanisms that place the foot in the zone of minimum risk and assure the stability of the body. PMID- 29171983 TI - Growth differentiation factor (GDF-15) concentration combined with Ca125 levels in serum is superior to commonly used cancer biomarkers in differentiation of pancreatic mass. AB - BACKGROUND: Pancreatic cancer (PDAC) will have been the second leading cancer related death in the United States by 2020, according to current estimation. Its late manifestation and the lack of good early detection methods are the cause of extremely low survival rates. Therefore, there is an urgent need to develop highly sensitive and specific marker. GDF-15, a member of TGFbeta family, has recently emerged as a protein playing an important role in carcinogenesis of various neoplasms. OBJECTIVE: Our aim was to assess the potential of GDF-15, IL 17, IL-23 serum concentration, and the panel of PDAC markers in differentiating pancreatic adenocarcinoma from chronic pancreatitis. METHODS: Sixty-three consecutive patients operated on due to pancreatobiliary lesions were enrolled in this study. Levels of CEA, CA125 and Ca19-9 were assessed using standard laboratory protocols. A sample of serum was collected prior to the surgery via central line. Levels of GDF-15, Il-17, Il-23 were measured using a ELISA kit. After standard pathological examination of specimens obtained on surgery, patients were divided into 2 groups: 42 patients with pancreatic adenocarcinoma and 21 patients with focal chronic pancreatitis. RESULTS: Mean GDF-15 concentration in patients with CP vs PDAC was 2247.95 (+/- 179.27) vs 7694.58 (+/ 1878.94) [pg/mL] respectively (p= 0.011). Mean concentration of Il-17, Il-23, Ca19-9, Ca125, Ca15-3, CEA in patients with CP and PDAC was 862.36 (+/- 30.84) vs 841.83 (+/- 33.94) p= 0.833; 127.85 (+/- 5.87) vs 127.51 (+/- 9.74) p= 0.175; 34.95 (+/- 23.34) vs 266.62 (+/- 49.7) p= 0.001; 13.4 (+/- 1.6) vs 39.27 (+/- 6.85) p= 0.005; 18.4 (+/- 1.48) vs 20.2 (+/- 1.38) p= 0.416; 1.96 (+/- 0.38) vs 5.93 (+/- 1.74) p= 0.004 respectively. In order to compare these markers with the routinely used ones, ROC curve was built. CA19-9 with clinically used cut-off point of ? 36 IU/mL has specificity of 90.5% and sensitivity of 57.14%. At the same time GDF-15 with the optimal cut-off point of 2.7 ng/mL has specificity of 76.19% and sensitivity of 73.8%. Although in our research group CA19-9 has an excellent specificity, its usefulness is hampered by its low sensitivity. On the other hand, GDF-15 parameters are well-balanced making it a more useful biomarker of PDAC. CONCLUSIONS: In conclusion, GDF-15 is more accurate than Ca19-9 in differentiating pancreatic mass due to chronic pancreatitis from pancreatic adenocarcinoma. Interleukin 17 and 23 cannot be considered as PDAC biomarkers. GDF-15 concentration in serum should be further investigated in order to assess their usefulness in pancreatic adenocarcinoma diagnosis. PMID- 29171984 TI - MicroRNA-1246 inhibits cell invasion and epithelial mesenchymal transition process by targeting CXCR4 in lung cancer cells. AB - BACKGROUND: Recent studies have indicated that microRNAs (miRNAs) are closely related to lung cancer. However, the effects of miR-1246 on lung cancer are still elusive. In this study, we aimed to explore the molecular mechanisms of miR-1246 in lung cancer. MATERIALS AND METHODS: Using RT-qPCR assay, we analyzed the expression of miR-1246 in lung cancer cell lines and lung epithelial cell line. Using Cell Counting Kit-8 (CCK-8), flow cytometry, Transwell, RT-qPCR and western blot assays, we investigated cell viability, apoptosis, invasion and epithelial mesenchymal transition (EMT) process. Using luciferase reporter assay, we confirmed a target of miR-1246. Using western blot assay, we detected the protein mechanisms of Janus kinase (JAK)/signal transducer and activator of transcription (STAT) and phosphatidylinositol 3 kinase (PI3K)/protein kinase B (AKT) signal pathways. RESULTS: Our results showed that miR-1246 was down-regulated in lung cancer cell lines (A549, H1650 and H1299) compared to in lung epithelial cell line (16HBE14o). MiR-1246 overexpression remarkably inhibited cell invasion as well as up-regulated E-cadherin expression and down-regulated N-cadherin, Vimentin, ZEB1 and Snail expressions in A549 cells. Further studies have confirmed CXCR4 as a target gene of miR-1246, and CXCR4 silence significantly abolished the promotion effect of miR-1246 suppression on cell invasion and EMT process in A549 cells. Besides, miR-1246 blocked JAK/STAT and PI3K/AKT signal pathways by regulation of CXCR4. CONCLUSIONS: These results demonstrated that miR 1246 inhibited cell invasion and EMT process by targeting CXCR4 and blocking JAK/STAT and PI3K/AKT signal pathways in lung cancer cells. PMID- 29171985 TI - Low-level serum miR-24-2 is associated with the progression of colorectal cancer. AB - BACKGROUND: colorectal cancer (CRC) is the second leading cause of cancer and cancer-related death in the world. Noninvasive biomarkers for early diagnosis of CRC are highly demanded. OBJECTIVE: The up-regulation of specific microRNAs (miRNAs) in serum has been considered a promising biomarker of CRC and miR-24-2 may be a potential biomarker in the diagnosis the progression of CRC. METHODS: Sixty-eighty healthy subjects and 228 CRC patients were divided into six groups: control group, CRC 0, CRC I, CRC II, CRC III, CRC IV and CRC V. Serum level of miR-24-2 was measured by real-time qPCR. Serum lipid profiles and oxidative related molecules were also measured. RESULTS: Serum levels of miR-24-2 in CRC patients were significantly higher than healthy subjects (p< 0.05). In addition, the expression level of the miR-24-2 was decreased with the progression of CRC and reached the lowest level in CRC V. Spearman Rank Correlation analysis showed that miR-24-2 level was negatively related to the levels of superoxide dismutase (SOD) and reduced glutathione (GSH), aspartate transaminase (AST), alanine transaminase (ALT), cholesterol and triglyceride (p< 0.05). CONCLUSIONS: Serum miR-24-2 is a potential negative biomarker in the diagnosis of the progression of CRC patients and associated with biochemical indices.

AB - OBJECTIVE: To explore the correlation of PD-1/PD-L1 polymorphisms and their expressions with clinicopathologic features and prognosis of ovarian cancer. METHODS: A total of 164 patients with ovarian cancer were enrolled as case group and 170 healthy women as control group. We conducted quantitative reverse transcription-PCR (qRT-PCR) to determine PD-1/PD-L1 expressions in peripheral blood mononuclear cells (PBMCs). Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele-specific amplification were used to detect PD-1 rs2227982 C>T and PD-L1 rs4143815 C>G. RESULTS: PD-1 rs2227982 C>T and PD-L1 rs4143815 C>G polymorphisms increased the risk for ovarian cancer. PD-1 rs2227982 C>T was associated with FIGO stage and differentiation grade, while PD L1 rs4143815 C>G was correlated with histological type and differentiation grade. Besides, PD-1/PD-L1 expressions were positively correlated in PBMCs of patients with ovarian cancer to be associated with differentiation grade. Compared with wild homozygous patients, PD-1/PD-L1 expressions were significantly decreased in PBMCs of ovarian cancer patients carried with the mutant genotypes of rs2227982 C>T and rs4143815 C>G. The PFS and OS in ovarian cancer patients with wild homozygous genotype of rs2227982 C>T and rs4143815 C>G were significantly higher than those with mutant genotypes, which were significantly lower in patients with low expressions of PD-1/PD-L1 than those with high expressions. Univariate COX regression analysis identified FIGO staging, differentiation grade, rs2227982 C>T, rs4143815 C>G and expressions of PD-1/PD-L1 as the prognostic factors, and multivariate COX regression analysis demonstrated that high FIGO stage and low expressions of PD-1/PD-L1 were independent risk factors for the prognosis of ovarian cancer. CONCLUSION: PD-1 rs2227982 C>T and PD-L1 rs4143815 C>G polymorphisms increased the risk of ovarian cancer, leading to a poor prognosis, associated with low expressions of PD-1 and PD-L1. While high PD-1 and PD-L1 expressions are indicators of a favorable prognosis in ovarian cancer. PMID- 29171987 TI - Dysregulation of miR-126/Crk protein axis predicts poor prognosis in gastric cancer patients. AB - BACKGROUND: miR-126 functions as a tumor suppressor in gastric cancer (GC) by negatively regulating Crk protein expression post-transcriptionally. OBJECTIVE: The aim of this study was to investigate the associations of miR-126 and Crk protein expression levels, alone or in combination, with the clinicopathological characteristics and prognosis of GC patients. METHODS: The expression levels of miR-126 and Crk protein in 338 GC patients were analyzed by quantitative real time polymerase chain reaction and immunohistochemistry, respectively. The relationship of miR-126 and Crk protein expression with clinicopathologic characteristics and clinical outcome was evaluated. RESULTS: Compared with matched adjacent non-tumor tissues, miR-126 was significantly down-regulated while Crk protein was significantly up-regulated in tumor tissues. A reduced miR 126 expression and an elevated Crk protein expression, alone or in combination, statistically correlated with aggressive clinicopathological characteristics, such as larger tumor size, deeper local invasion, more lymph node metastasis, advanced TNM stage, and poorer prognosis. Multivariate analysis showed that combined miR-126-low/Crk protein-high expression was an independent unfavorable prognostic factor of GC. CONCLUSIONS: These results indicate for the first time that miR-126 down-regulation and Crk protein up-regulation may be synergistically associated with tumor progression in GC and may predict unfavorable prognosis of GC. PMID- 29171988 TI - High expression of NDRG3 associates with unfavorable overall survival in non small cell lung cancer. AB - BACKGROUND AND OBJECTIVE: N-myc downstream-regulated gene 3 (NDRG3) is one of the important members of the NDRG family which crucially take part in cell proliferation, differentiation and other biological processes. METHODS: In this present study, western-blotting analysis was performed to evaluate NDRG3 expression in NSCLC cell lines. One-step quantitative reverse transcription polymerase chain reaction (qPCR) with 16 fresh-frozen NSCLC samples and immunohistochemistry (IHC) analysis in 100 NSCLC cases were conducted to explore the relationship between NDRG3 expression and the clinicopathological characteristics of NSCLC. RESULTS: NDRG3 expression levels were statistically higher in NSCLC cell lines and tissue samples, compared with that of in non cancerous cell line and tissue samples (p< 0.05). The IHC data demonstrated that the NDRG3 expression was significantly correlated with pathological grade (p= 0.038), N (p= 0.020) and TNM stage (p= 0.002). Survival analysis and Kaplan-Meier curve indicated that NDRG3 expression (p= 0.002) and T (p= 0.047) were independently associated with the unfavorable overall survival of patients with NSCLC. CONCLUSIONS: The data implied that NDRG3 expression may be identified as a new predictor in NSCLC prognosis. PMID- 29171989 TI - Comparative analysis of immune function, hemorheological alterations and prognosis in colorectal cancer patients with different traditional Chinese medicine syndromes. AB - OBJECTIVE: The present study investigates the differences in immune function, hemorheological alterations and prognostic evaluation in colorectal cancer (CRC) patients with different traditional Chinese medicine (TCM) syndromes. METHODS: A total of 128 patients, diagnosed as stage II and III of CRC, were recruited. They were assigned into three TCM syndromes: deficiency syndrome, excess syndrome, and syndrome of intermingled deficiency and excess, and another 53 healthy individuals were selected as the control. Flow cytometry was used to determine the peripheral blood lymphocyte subsets (the levels of CD+3, CD+4, CD+8, NK cells, and the ratios of CD+4/CD+8, Th1/Th2 and Tc1/Tc2). Whole blood viscosity (WBV), plasma viscosity (PV), hematocrit (Hct), erythrocyte sedimentation rate (ESR), plasma fibrinogen concentration (PFC) were measured using a fully automatic blood rheological instrument. The univariate analysis and Cox regression analysis were conducted to evaluate the prognosis of CRC patients with different TCM syndromes. RESULTS: Compared with healthy individuals, CRC patients with three different syndromes had lower levels of CD+3, CD+4, NK cells, and ratios of CD+4/CD+8, Th1/Th2 and Tc1/Tc2, but higher level of CD+8, WBV, PV, Hct, ESR and PFC. Besides, patients with excess syndrome showed the highest levels of CD3+, CD4+ and NK cells, and ratios of CD+4/CD+8, Th1/Th2 and Tc1/Tc2, but the lowest level of CD+8 among three syndromes, and those with deficiency syndrome showed an opposite trend. Compared with patients with excess syndrome, those with deficiency syndrome showed decreased WBV, PV, Hct, ESR and PFC. The pathological type, surgical approach, tumor node metastasis (TNM) stage, liver metastasis, TCM treatment time and different TCM syndromes were independent factors of prognostic survival in CRC patients except perioperative blood transfusion volume. CONCLUSIONS: Taken together, we conclude that patients with TCM deficiency syndrome has lower immune function and poorer prognosis while patients with TCM excess syndrome has higher immune function and better prognosis of CRC. PMID- 29171990 TI - Development of nanoparticle adjuvants to potentiate the immune response against diphtheria toxoid. AB - BACKGROUND: Over the years, diphtheria was known as contagious fatal infection caused by Corynebacterium diphtheria that affects upper respiratory system. The spread of diphtheria epidemic disease is best prevented by vaccination with diphtheria toxoid vaccine. Aluminum adjuvants were reported to stimulate the immune responses to killed and subunit vaccines. OBJECTIVE: Our study aimed to minimize adjuvant particles size, to gain insight of resulting immunity titer and impact on immune response antibody subtypes. METHODS: Aluminum salts and calcium phosphate adjuvants were prepared, followed by micro/nanoparticle adjuvants preparation. After formulation of diphtheria vaccine from diphtheria toxoid and developed adjuvants, we evaluated efficacy of these prepared vaccines based on their impact on immune response via measuring antibodies titer, antibodies isotyping and cytokines profile in immunized mice. RESULTS: A noteworthy increase in immunological parameters was observed; antibodies titer was higher in serum of mice injected with nanoparticle adjuvants-containing vaccine than mice injected with standard adjuvant-containing vaccine and commercial vaccine. Aluminum compounds adjuvants (nanoparticles and microparticles formulation) and microparticles calcium phosphate adjuvant induce TH2 response, while nanoparticles calcium phosphate and microparticles aluminum compounds adjuvants stimulate TH1 response. CONCLUSIONS: Different treatments to our adjuvant preparations (nanoparticles and microparticles formulation) had a considerable impact on vaccine immunogenicity. PMID- 29171991 TI - Concordance Between Cerebrospinal Fluid Biomarkers with Alzheimer's Disease Pathology Between Three Independent Assay Platforms. AB - BACKGROUND: To enhance the accuracy of clinical diagnosis for Alzheimer's disease (AD), pre-mortem biomarkers have become increasingly important for diagnosis and for participant recruitment in disease-specific treatment trials. Cerebrospinal fluid (CSF) biomarkers provide a low-cost alternative to positron emission tomography (PET) imaging for in vivo quantification of different AD pathological hallmarks in the brains of affected subjects; however, consensus around the best platform, most informative biomarker and correlations across different methodologies are controversial. OBJECTIVE: Assessing levels of Abeta-amyloid and tau species determined using three different versions of immunoassays, the current study explored the ability of CSF biomarkers to predict PET Abeta-amyloid (32 Abeta-amyloid-and 45 Abeta-amyloid+), as well as concordance between CSF biomarker levels and PET Abeta-amyloid imaging. METHODS: Prediction and concordance analyses were performed using a sub-cohort of 77 individuals (48 healthy controls, 15 with mild cognitive impairment, and 14 with AD) from the Australian Imaging Biomarker and Lifestyle study of aging. RESULTS: Across all three platforms, the T-tau/Abeta42 ratio biomarker had modestly higher correlation with SUVR/BeCKeT (rho= 0.69-0.8) as compared with Abeta42 alone (rho= 0.66-0.75). Differences in CSF biomarker levels between the PET Abeta-amyloid-and Abeta-amyloid+ groups were strongest for the Abeta42/Abeta40 and T-tau/Abeta42 ratios (p < 0.0001); however, comparison of predictive models for PET Abeta amyloid showed no difference between Abeta42 alone and the T-tau/Abeta42 ratio. CONCLUSION: This study confirms strong concordance between CSF biomarkers and PET Abeta-amyloid status is independent of immunoassay platform, supporting their utility as biomarkers in clinical practice for the diagnosis of AD and for participant enrichment in clinical trials. PMID- 29171992 TI - Delirium Severity Post-Surgery and its Relationship with Long-Term Cognitive Decline in a Cohort of Patients without Dementia. AB - BACKGROUND: Delirium has been associated with more rapid cognitive decline. However, it is unknown whether increased delirium severity is associated with a higher rate of long-term cognitive decline. OBJECTIVE: To evaluate delirium severity and the presence and rate of cognitive decline over 36 months following surgery. METHODS: We examined patients from the Successful Aging after Elective Surgery Study, who were age >=70 years undergoing major elective surgery (N = 560). Delirium severity was determined by the peak Confusion Assessment Method Severity (CAM-S) score for each patient's hospitalization and grouped based on the sample distribution: scores of 0-2, 3-7, and 8-19. A neuropsychological composite, General Cognitive Performance (GCP), and proxy-reported Informant Questionnaire for Cognitive Decline (IQCODE) were used to examine cognitive outcomes following surgery at 0, 1, and 2 months, and then every 6 months for up to 3 years. RESULTS: No significant cognitive decline was observed for patients with peak CAM-S scores 0-2 (-0.17 GCP units/year, 95% confidence interval [CI] 0.35, 0.01). GCP scores decreased significantly in the group with peak CAM-S scores 3-7 (-0.30 GCP units/year, 95% CI -0.51, -0.09), and decreased almost three times faster in the highest delirium severity group (peak CAM-S scores 8 19; -0.82 GCP units/year, 95% CI -1.28, -0.37). A similar association was found for delirium severity and the proportion of patients who developed IQCODE impairment over time. CONCLUSION: Patients with the highest delirium severity experienced the greatest rate of cognitive decline, which exceeds the rate previously observed for patients with dementia, on serial neuropsychological testing administered over 3 years, with a dose-response relationship between delirium severity and long-term cognitive decline. PMID- 29171993 TI - Prevalence of Delirium in a Population of Elderly Outpatients with Dementia: A Retrospective Study. AB - BACKGROUND: Delirium is a multifactorial geriatric syndrome and often occurs in patients with cognitive impairment. It also remains under-recognized, specifically in elderly outpatients, because signs of delirium might overlap with symptoms of dementia. OBJECTIVE: The aim of the present study is to retrospectively apply the chart-based delirium instrument on a cohort of elderly outpatients with dementia, to assess prevalence and features of delirium in this population. METHODS: We randomly selected 650 medical records of outpatients referred to the "Neurogenetic Regional Centre" (CRN) of Lamezia Terme. Each evaluation included demographics, medical history, drugs, type and severity of dementia, and cognitive and functional status. Delirium was identified by the application of the chart-based delirium instrument. RESULTS: The prevalence of delirium was 13.3%. The study population was divided, according to the presence of delirium, into two subgroups. Compared to the no delirium group, the delirium group was significantly older and had greater cognitive impairment with lower MMSE scores both at baseline and at the end of the follow up. They also had a significant lower score on the ADL and IADL. In this group, a higher intake of antihypertensive and antipsychotic drugs, together with a lower intake of cholinesterase inhibitors and memantine, was observed. CONCLUSIONS: In this study, the chart-based delirium instrument was applied to an outpatient population affected by dementia and followed for a long time. Our data confirm the importance that age and frailty play on the genesis of delirium and suggest attention should be paid to the pharmacological treatment of these patients. PMID- 29171995 TI - High Caregiver Burden in Young Onset Dementia: What Factors Need Attention? AB - BACKGROUND: There is an increase in prevalence of young onset dementia (YOD). The specific problems among YOD patients and levels of caregiver burden (CB) in this group warrants further evaluation. OBJECTIVE: To evaluate and compare level of CB in YOD and late onset dementia (LOD). Also, we sought to understand the specific factors, such as neuropsychiatric symptoms, that may affect the levels of caregiver burden in the YOD group. METHODS: Patient-caregiver dyads with YOD and LOD were recruited from a tertiary neurology center. Levels of CB between YOD and LOD were compared among 183 patient-caregiver dyads. CB was quantified using the Zarit Burden Inventory (ZBI). Neuropsychological evaluations as well as the Neuropsychiatric Inventory were performed. Factors that influenced level of CB in YOD group was investigated with regression analyses. RESULTS: There were 57 YOD and 126 LOD dyads. Caregivers of YOD subjects reported significantly higher levels of burden compared to caregivers of LOD subjects (ZBI: 17.3 versus 13.94; p = 0.015). 52.6% of YOD caregivers reported a high caregiver burden. When compared to caregivers of LOD, the odds of a caregiver of YOD reporting high caregiver burden was 2.34 (95% CI: 1.22-4.49: p = 0.010). YOD dyads with a high caregiver burden had significantly higher neuropsychiatric inventory scores. Risk factors for high caregiver burden in YOD included family history of dementia and behavioral symptoms including disinhibited behavior, delusions, and apathy. CONCLUSION: Targeted support for caregivers of patients with YOD is needed to address the higher CB in this group. PMID- 29171994 TI - Hippocampal Stratum Radiatum, Lacunosum, and Moleculare Sparing in Mild Cognitive Impairment. AB - BACKGROUND: Alzheimer's disease (AD) is associated with atrophy in entorhinal cortex (ERC), the hippocampus, and its subfields Cornu Ammonis 1 (CA1) and subiculum, which predict conversion from mild cognitive impairment (MCI) to clinical AD. The stratum radiatum, lacunosum, and moleculare (SRLM) are also important gateways involving ERC and CA1, which are affected by early AD pathology. OBJECTIVE: To assess whether the SRLM is affected in MCI and AD. METHODS: In this proof-of-concept study, 27 controls, 13 subjects with AD, and 22 with MCI underwent 3T MRI. T1 maps were used for whole-hippocampal volumetry, T2 maps were segmented for hippocampal subfield areas, entorhinal cortex and subiculum thickness, and evaluated for SRLM integrity. RESULTS: Significant CA1 atrophy and subiculum thinning were found in both AD and MCI compared to similarly aged controls. However, SRLM integrity was only significantly reduced in AD but not in MCI compared to controls. There were no significant differences in other hippocampal subfields (CA2, CA3/dentate gyrus) or ERC thickness between the groups. Finally, CA1 and CA3/DG areas and SRLM clarity were correlated with clinical and cognitive measurements of disease severity. CONCLUSION: Although this study was cross sectional, it suggests a progression of specific subfield changes from MCI to established AD that is associated with the reduced integrity of SRLM, which may reflect more widespread hippocampal involvement as the disease progresses and the relative preservation of SRLM in MCI. These results provide new MRI biomarkers for disease staging and understanding of the neurobiology in AD. PMID- 29171996 TI - Cerebrospinal Fluid C-C Motif Chemokine Ligand 2 Correlates with Brain Atrophy and Cognitive Impairment in Alzheimer's Disease. AB - BACKGROUND: Chronic neuroinflammation has been implicated in Alzheimer's disease (AD) pathology. OBJECTIVE: To investigate the association between cytokine and anti-amyloid-beta (Abeta) autoantibody levels and the degree of brain atrophy and cognitive impairment in AD patients. METHODS: Cerebrospinal fluid (CSF) levels of C-C motif chemokine ligand 2 (CCL2), C-X-C motif chemokine ligand 8, C-X-C motif chemokine ligand 10, interleukin 6, and anti-Abeta autoantibody were evaluated in 69 AD patients. Serum levels of CCL2 and anti-Abeta autoantibody were also examined. The degree of brain atrophy was assessed using the voxel-based specific regional analysis system for AD, which targets the volumes of interest (VOI) in medial temporal structures. Cognitive function was evaluated by neuropsychological testing, including the Mini-Mental State Examination (MMSE) and Frontal Assessment Battery (FAB). RESULTS: CSF CCL2 levels correlated significantly with the severity (p = 0.023) and the extent (p = 0.022) of VOI atrophy, and with the extent of gray matter atrophy (p = 0.039) in AD patients. CSF anti-Abeta autoantibody levels were inversely correlated with the severity of VOI atrophy (p = 0.020), the extent of VOI atrophy (p = 0.015), and the ratio of VOI/GM atrophy (r = -0.358, p = 0.004). CSF CCL2 levels were also inversely correlated with MMSE (p = 0.0497) and FAB scores (p = 0.016). CONCLUSIONS: CSF CCL2 levels are associated with the degree of medial temporal lobe and gray matter atrophy, and cognitive decline in AD. PMID- 29171997 TI - Tau and Amyloid Positron Emission Tomography Imaging Predict Driving Performance Among Older Adults with and without Preclinical Alzheimer's Disease. AB - Abnormal levels of Alzheimer's disease (AD) biomarkers, measured by positron emission tomography imaging using amyloid-based radiotracers and cerebrospinal fluid, are associated with impaired driving performance in older adults. We examined whether preclinical AD staging, defined using amyloid imaging and tau imaging using the radiotracer T807 (AKA flortaucipir or AV-1451), was associated with receiving a marginal/fail rating on a standardized road test (n = 42). Participants at Stage 2 (positive amyloid and tau scans) of preclinical AD were more likely to receive a marginal/fail rating compared to participants at Stage 0 or 1. Stage 2 preclinical AD may manifest in worse driving performance. PMID- 29171999 TI - ABC Transporters Are Key Players in Alzheimer's Disease. AB - Human ATP-binding cassette (ABC) transporters mediate a critical function in the cell, namely the transport of molecules across lipid membranes. Associated to their ubiquitous tissue distribution, they are key players in cellular homeostasis but also potential causative or contributing factors for many pathologies, including Alzheimer's disease (AD). In the central nervous system (CNS), numerous ABC transporters are present throughout the brain parenchyma and especially at the blood-brain barrier (BBB). AD is a neurodegenerative disorder mainly characterized by extracellular deposition of amyloid-beta (Abeta) peptides and intracellular accumulation of hyperphosphorylated forms of tau protein. Besides being degraded via proteolytic and phagocytic processes mediated by brain parenchymal cells, a major mechanism for eliminating cerebral Abeta is through its transport across the BBB into the peripheral blood. In fact, many AD cases are associated with impaired Abeta clearance. Consistently, several studies have recently uncovered important roles for ABC transporters in AD pathophysiology. Hence, this review focuses on the relevance of ABC transporters in CNS homeostasis by highlighting AD as a strong example of the deleterious consequences that might result from the former's altered expression and/or activity in the brain. The potentiality of human ABC transporters as novel pharmacological targets for both the diagnosis and therapeutics of AD is emphasized. PMID- 29171998 TI - Biological, Neuroimaging, and Neurophysiological Markers in Frontotemporal Dementia: Three Faces of the Same Coin. AB - Frontotemporal dementia (FTD) is a heterogeneous clinical, genetic, and neuropathological disorder. Clinical diagnosis and prediction of neuropathological substrates are hampered by heterogeneous pictures. Diagnostic markers are key in clinical trials to differentiate FTD from other neurodegenerative dementias. In the same view, identifying the neuropathological hallmarks of the disease is key in light of future disease-modifying treatments. The aim of the present review is to unravel the progress in biomarker discovery, discussing the potential applications of available biological, imaging, and neurophysiological markers. PMID- 29172002 TI - Mental States in Moving Shapes: Distinct Cortical and Subcortical Contributions to Theory of Mind Impairments in Dementia. AB - Impaired capacity for Theory of Mind (ToM) represents one of the hallmark features of the behavioral variant of frontotemporal dementia (bvFTD) and is suggested to underpin an array of socioemotional disturbances characteristic of this disorder. In contrast, while social processing typically remains intact in Alzheimer's disease (AD), the cognitive loading of socioemotional tasks may adversely impact mentalizing performance in AD. Here, we employed the Frith-Happe animations as a dynamic on-line assessment of mentalizing capacity with reduced incidental task demands in 18 bvFTD, 18 AD, and 25 age-matched Controls. Participants viewed silent animations in which geometric shapes interact in Random, Goal-Directed, and ToM conditions. An exclusive deficit in ToM classification was observed in bvFTD relative to Controls, while AD patients were impaired in the accurate classification of both Random and ToM trials. Correlation analyses revealed robust associations between ToM deficits and carer ratings of affective empathy disruption in bvFTD, and with episodic memory dysfunction in AD. Voxel-based morphometry analyses further identified dissociable neural correlates contingent on patient group. A distributed network of medial prefrontal, frontoinsular, striatal, lateral temporal, and parietal regions were implicated in the bvFTD group, whereas the right hippocampus correlated with task performance in AD. Notably, subregions of the cerebellum, including lobules I-IV and V, bilaterally were implicated in task performance irrespective of patient group. Our findings reveal new insights into the mechanisms potentially mediating ToM disruption in dementia syndromes, and suggest that the cerebellum may play a more prominent role in social cognition than previously appreciated. PMID- 29172001 TI - Co-Expression of Glia Maturation Factor and Apolipoprotein E4 in Alzheimer's Disease Brain. AB - Apolipoprotein E4 (ApoE4) is a major genetic risk factor for Alzheimer's disease (AD). The E4 allele of ApoE plays a crucial role in the inflammatory and neurodegenerative processes associated with AD. This is evident from the multiple effects of the ApoE isoforms in amyloid-beta (Abeta) aggregation. Glia maturation factor (GMF) is a brain-specific neuroinflammatory protein that we have previously demonstrated to be significantly upregulated in various regions of AD brains compared to non-AD control brains and that it induces neurodegeneration. We have previously reported that GMF is predominantly expressed in the reactive astrocytes surrounding amyloid plaques (APs) in AD brain. In the present study, using immunohistochemical and dual immunofluorescence staining, we show the expression and colocalization of GMF and ApoE4 in AD brains. Our results show that ApoE4 is present within the APs of AD brain. Further, we found that GMF and ApoE4 were strongly expressed and co-associated in APs and in the reactive astrocytes surrounding APs in AD. An increased expression of GMF in APs and neurofibrillary tangles in the AD brain, and the co-localization of GMF and ApoE4 in APs suggest that GMF and ApoE4 together should be contributing to the neuropathological changes associated with AD. PMID- 29172000 TI - Translational Research in Alzheimer's and Prion Diseases. AB - Translational neuroscience integrates the knowledge derived by basic neuroscience with the development of new diagnostic and therapeutic tools that may be applied to clinical practice in neurological diseases. This information can be used to improve clinical trial designs and outcomes that will accelerate drug development, and to discover novel biomarkers which can be efficiently employed to early recognize neurological disorders and provide information regarding the effects of drugs on the underlying disease biology. Alzheimer's disease (AD) and prion disease are two classes of neurodegenerative disorders characterized by incomplete knowledge of the molecular mechanisms underlying their occurrence and the lack of valid biomarkers and effective treatments. For these reasons, the design of therapies that prevent or delay the onset, slow the progression, or improve the symptoms associated to these disorders is urgently needed. During the last few decades, translational research provided a framework for advancing development of new diagnostic devices and promising disease-modifying therapies for patients with prion encephalopathies and AD. In this review, we provide present evidence of how supportive can be the translational approach to the study of dementias and show some results of our preclinical studies which have been translated to the clinical application following the 'bed-to-bench-and-back' research model. PMID- 29172003 TI - Functional brain dynamic analysis of ADHD and control children using nonlinear dynamical features of EEG signals. AB - Attention deficit hyperactivity disorder is a neurodevelopmental condition associated with varying levels of hyperactivity, inattention, and impulsivity. This study investigates brain function in children with attention deficit hyperactivity disorder using measures of nonlinear dynamics in EEG signals during rest. During eyes-closed resting, 19 channel EEG signals were recorded from 12 ADHD and 12 normal age-matched children. We used the multifractal singularity spectrum, the largest Lyapunov exponent, and approximate entropy to quantify the chaotic nonlinear dynamics of these EEG signals. As confirmed by Wilcoxon rank sum test, largest Lyapunov exponent over left frontal-central cortex exhibited a significant difference between ADHD and the age-matched control groups. Further, mean approximate entropy was significantly lower in ADHD subjects in prefrontal cortex. The singularity spectrum was also considerably altered in ADHD compared to control children. Evaluation of these features was performed by two classifiers: a Support Vector Machine and a Radial Basis Function Neural Network. For better comparison, subject classification based on frequency band power was assessed using the same types of classifiers. Nonlinear features provided better discrimination between ADHD and control than band power features. Under four-fold cross validation testing, support vector machine gave 83.33% accurate classification results. PMID- 29172004 TI - Early-Onset Myopathies: Clinical Findings, Prevalence of Subgroups and Diagnostic Approach in a Single Neuromuscular Referral Center in Germany. AB - BACKGROUND: Early-onset myopathies are a heterogeneous group of neuromuscular diseases with broad clinical, genetic and histopathological overlap. The diagnostic approach has considerably changed since high throughput genetic methods (next generation sequencing, NGS) became available. OBJECTIVE: We present diagnostic subgroups in a single neuromuscular referral center and describe an algorithm for the diagnostic work-up. METHODS: The diagnostic approach of 98 index patients was retrospectively analysed. In 56 cases targeted sequencing of a known gene was performed, in 44 patients NGS was performed using large muscle specific panels, and in 12 individuals whole exome sequencing (WES) was undertaken. One patient was diagnosed via array CGH. Clinical features of all patients are provided. RESULTS: The final diagnosis could be found in 63 out of 98 patients (64%) with molecular genetic analysis. In 55% targeted gene sequencing could establish the genetic diagnosis. However, this rate largely depended on the presence of distinct histological or clinical features. NGS (large myopathy-related panels and WES) revealed genetic diagnosis in 58.5% (52% and 67%, respectively). The genes detected by WES in our cohort of patients were all covered by the panels. Based on our findings we propose an algorithm for a practical diagnostic approach.Prevalences:MTM1- and LAMA2-patients are the two biggest subgroups, followed by SEPN1-, RYR1- and Collagen VI-related diseases. 31% of genetically confirmed cases represents a group with overlap between "congenital myopathies (CM)" and "congenital muscular dystrophies (CMD)". In 36% of the patients a specific genetic diagnosis could not be assigned. CONCLUSIONS: A final diagnosis can be confirmed by high throughput genetic analysis in 58.5% of the cases, which is a higher rate than reported in the literature for muscle biopsy and should in many cases be considered as a first diagnostic tool. NGS cannot replace neuromuscular expertise and a close discussion with the geneticists on NGS is mandatory. Targeted candidate gene sequencing still plays a role in selected cases with highly suspicious clinical or histological features. There is a relevant clinical and genetic overlap between the entities CM and CMD. PMID- 29172005 TI - Cytokine Profiling of Serum Allows Monitoring of Disease Progression in Inclusion Body Myositis. AB - BACKGROUND: Inclusion body myositis is a late onset inflammatory myopathy lacking reliable serum biomarkers for diagnosis and for disease progression. OBJECTIVE: To identify diagnostic and predictive biomarkers, cytokine profiling is used to assess the potential of cytokines to discriminate between cases and controls and to assess whether treatment with methotrexate can influence biomarkers associated with disease progression. METHODS: The diagnostic and follow-up potential of 48 cytokines was tested using Bioplex-assay and ELISA in sera of healthy individuals, IBM patients and patients with other neuromuscular disorders. RESULTS: Ten cytokines (TRAIL, IL-8, MIF, MCP-1, LIF, IP-10, IFN-alpha2, MIG, bNGF and IL-3) were identified to be good to excellent markers to discern IBM patients from healthy controls. Three cytokines (IP-10, Eotaxin and SDF1A) changed significantly upon methotrexate treatment as compared with the natural clinical course. Muscle strength loss was associated with changes in IL-8 and SDF1A levels. IFN-gamma levels were only associated with survival of IBM patients before correction for multiple comparisons. DISCUSSION: Cytokine profiling can discriminate IBM patients from healthy controls and other neuromuscular disorders. Immunosuppression with methotrexate affects cytokine levels in IBM. IL 8 and SDF1A could serve as biomarkers for disease progression. PMID- 29172006 TI - Two Cases of Spinal Muscular Atrophy Type II with Eosinophilic Oesophagitis. AB - Although primarily characterised by loss of motor neurons from the anterior horn of spinal cord and muscle atrophy, spinal muscular atrophy (SMA) is now recognised as a multi-systemic disorder. Here, we report two SMA Type II patients with eosinophilic oesophagitis (EoE), a rare, chronic immune/antigen-mediated condition. One patient presented with dysphagia and poor weight gain, and the second patient had symptoms of gastro-oesophageal reflux (GOR) and poor weight gain. In both patients, macroscopic observations during gastroscopy indicated typical signs of EoE, which were verified during histological examination of oesophageal biopsies. Given that there is a specific treatment strategy for EoE, these cases highlight the importance of considering this condition in clinical investigations - especially for patients with SMA - who have GOR, discomfort, and oral aversion. PMID- 29172007 TI - Frequency-specific effects of repetitive magnetic stimulation on primary astrocyte cultures. AB - BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive technique that uses magnetic pulses over the cranium to induce electrical currents in underlying cortical tissue. Although rTMS has shown clinical utility for a number of neurological conditions, we have only limited understanding of how rTMS influences cellular function and cell-cell interactions. OBJECTIVE: In this study, we sought to investigate whether repeated magnetic stimulation (rMS) can influence astrocyte biology in vitro. METHOD: We tested four different rMS frequencies and measured the calcium response in primary neonatal astrocyte cultures. We also tested the effect of rMS on astrocyte migration and proliferation in vitro. We tested 3 to 4 culture replicates and 17 to 34 cells for each rMS frequency (sham, 1 Hz, cTBS, 10 Hz and biomemetic high frequency stimulation - BHFS). RESULTS: Of all frequencies tested, 1 Hz stimulation resulted in a statistically significant rise in intracellular calcium in the cytoplasmic and nuclear compartments of the cultured astrocytes. This calcium rise did not affect migration or proliferation in the scratch assay, though astrocyte hypertrophy was reduced in response to 1 Hz rMS, 24 hours post scratch injury. CONCLUSION: Our results provide preliminary evidence that rMS can influence astrocyte physiology, indicating the potential for a novel mechanism by which rTMS can influence brain activity. PMID- 29172008 TI - Effects of cerebrolysin on nerve growth factor system in the aging rat brain. AB - BACKGROUND: Aging is associated with some cognitive decline and enhanced risk of development of neurodegenerative diseases. It is assumed that altered metabolism and functions of neurotrophin systems may underlie these age-related functional and structural modifications. CerebrolysinTM (CBL) is a neuropeptide mixture with neurotrophic effects, which is widely used for the treatment of stroke and traumatic brain injury patients. It is also evident that CBL has an overall beneficial effect and a favorable benefit-risk ratio in patients with dementia. However, the effects of CBL on cognition and brain neurotrophin system in normal aging remain obscure. OBJECTIVE: The aim of the present study was to examine the age-related modifications of endogenous neurotrophin systems in the brain of male Wistar rats and the effects of CBL on learning and memory as well as the levels neurotrophins and their receptors. METHODS: Old (23-24 months) and young (2-3 months) male Wistar rats were used for the study. A half of animals were subjected to CBL course (2.5 ml/kg, 20 i.p. injections). Behavior of rats was studied using the open field test and simple water maze training. The contents of NGF and BDNF were studied using enzyme-linked immunosorbent assay; the expression of neurotrophin receptors was estimated by Western-blot analysis. RESULTS: CBL treatment did not affect general status, age-related weight changes, general locomotor activity as well as general brain histology. In a water maze task, a minor effect of CBL was observed in old rats at the start of training and no effect on memory retention was found. Aging induced a decrease in neurotrophin receptors TrkA, TrkB, and p75NTR in the neocortex. CBL counteracted effects of aging on neocortical TrkA and p75NTR receptors and decreased expression of proNGF without influencing overall NGF levels. BDNF system was not significantly affected by CBL. CONCLUSION: The pro-neuroplastic "antiaging" effects of CBL in the neocortex of old animals were generally related to the NGF rather than the BDNF system.

AB - BACKGROUND: Assessment of therapies for the key consequences of mild traumatic brain injury (mTBI)/concussion is required. OBJECTIVE: Identify all RCTs of mTBI/concussion therapy, risks of bias, and therapies with significant positive results. METHODS: 17 electronic, 9 grey-literature databases searched without language/date restrictions; independent assessment of 1450 Abstracts/titles, 141 fulltext articles, 14 included RCTs. RESULTS: Four RCTs used American Congress of Rehabilitation TBI definition, others used unique definitions. Risk of bias: 43% low risk randomization; 14% concealed assignments; 21% blinded participants/personnel; 57% blinded assessors; 64% low risk attrition; 100% no selective reporting. Eleven RCTs included only mTBI. Ten significant positive results: six cognitive behavioral therapy (CBT), three videotape, pagers or personal digital assistants, and one physical therapy. One of referrals to health professionals no significant positive results. Three RCTs included both mTBI and moderate TBI. We wished to assess if authors proved using same interventions with both groups is appropriate. Two used CBT, one used pagers. All three RCTs significant positive results but results for their mild and moderate TBI patients were not separated. Two RCTs assessed return to work and no differences between intervention. CONCLUSION: Of 14 RCTs, six CBT, four digital assistants or videotape feedback and one physical therapy all had significant positive results. One referred patients to consultants and no significant positive results. Two assessed return to employment and no differences between interventions. Limitations are: (1) only four RCTs used the same concussion definition; (2) average age 38 (except for one study of adolescents, (3) all studies used unique interventions; (4) most authors used multiple interventions and effects could not be separated; (5) substantial attrition from eligibles to randomization, (4) only 64% at low risk from randomization, (5) 80 different outcome measures and meta analysis was not possible, (6) only two studies assessed return to work.

AB - BACKGROUND: Spinal cord injury (SCI) is a debilitating condition characterized by a complex of neurological dysfunctions ranging from loss of sensation to partial or complete limb paralysis. Recently, we reported that intravenous administration of neural precursors physiologically releasing erythropoietin (namely Er-NPCs) enhances functional recovery in animals following contusive spinal cord injury through the counteraction of secondary degeneration. Er-NPCs reached and accumulated at the lesion edges, where they survived throughout the prolonged period of observation and differentiated mostly into cholinergic neuron-like cells. OBJECTIVE: The aim of this study was to investigate the potential reparative and regenerative properties of Er-NPCs in a mouse experimental model of traumatic spinal cord injury. METHODS AND RESULTS: We report that Er-NPCs favoured the preservation of axonal myelin and strongly promoted the regrowth across the lesion site of monoaminergic and chatecolaminergic fibers that reached the distal portions of the injured cord. The use of an anterograde tracer transported by the regenerating axons allowed us to assess the extent of such a process. We show that axonal fluoro-ruby labelling was practically absent in saline-treated mice, while it resulted very significant in Er-NPCs transplanted animals. CONCLUSION: Our study shows that Er-NPCs promoted recovery of function after spinal cord injury, and that this is accompanied by preservation of myelination and strong re-innervation of the distal cord. Thus, regenerated axons may have contributed to the enhanced recovery of function after SCI. PMID- 29172010 TI - Extended Multiple-Field High-Definition transcranial direct current stimulation (HD-tDCS) is well tolerated and safe in healthy adults. AB - BACKGROUND: High definition transcranial direct current stimulation (HD-tDCS) has been administered over single brain regions for small numbers of sessions. Safety, feasibility and tolerability of HD-tDCS over multiple brain regions, multiple daily stimulations and long periods are not established. OBJECTIVE: We studied safety, feasibility and tolerability of daily HD-tDCS over 2-4 brain regions for 20 sessions in healthy adults. METHODS: Five healthy adults underwent physical and neurological examination, electrocardiogram (EKG), electroencephalogram (EEG) and cognitive screening (ImpACT) before, during and after HD-tDCS. Four networks (left/right temporoparietal and frontal) were stimulated in sequence (20 min each) using HD-tDCS in 20 daily sessions. Sessions 1-10 included sequential stimulation of both temporoparietal networks, sessions 11-15 stimulations of 4 networks and sessions 16-20 two daily stimulation cycles of 4 networks/cycle (1.5 mA/network). Side effects, ImpACT scores and EEG power spectrum were compared before and after HD-tDCS. RESULTS: All subjects completed the trial. Adverse events were tingling, transient redness at the stimulation site, perception of continuing stimulation after end of session and one self resolving headache. EEG power spectrum showed decreased delta power in frontal areas several days after HD-tDCS. While at the group level ImpACT scores did not differ before and after stimulations, we found a trend for correlation between decreased EEG delta power and individual improvements in ImpACT scores after HD tDCS. CONCLUSION: Prolonged, repeat daily stimulation of multiple brain regions using HD-tDCS is feasible and safe in healthy adults. Preliminary EEG results suggest that HD-tDCS may induce long lasting changes in excitability in the brain. PMID- 29172012 TI - Do whole body vibration exercises affect lower limbs neuromuscular activity in populations with a medical condition? A systematic review. AB - BACKGROUND: The use of surface electromyography (sEMG) to evaluate muscle activation when executing whole body vibration exercises (WBVE) in studies provide neuromuscular findings, in healthy and diseased populations. OBJECTIVES: Perform a systematic review of the effects of WBVE by sEMG of lower limbs in non healthy populations. METHODS: The search using the defined keywords was performed in PubMed, PEDRo and EMBASE databases by three independent researchers. Applying the PRISMA statement several studies were selected according to eligibility criteria and organized for the review. Full papers were included if they described effects of WBVE for the treatment of illnesses, evaluated by sEMG of lower limbs independently on the year of the publication; in comparison or associated with other treatment and evaluation techniques. RESULTS: Seven publications were selected; two in spinal cord injury patients, one in Friedreich's ataxia patients, three in stroke patients and one study in breast cancer survivors. Reported effects of WBV in were muscle activation by sEMG and also on strength, blood flow and exercise resistance; even in paretic limbs. CONCLUSION: By the use of sEMG it was verified that WBVE elicits muscle activation in diseased population. These results may lead to the definition of exercise protocols to maintain or increase muscular activation. However, due to the heterogeneity of methods among studies, there is currently no consensus on the sEMG signal processing. These strategies might also induce effects on muscle strength, balance and flexibility in these and other illnesses.

AB - Impingement, tibial erosions, and "painful hardware" caused by a lag screw used for malleolar fracture stabilization are rare occurrences. We report a case of a symptomatic lag screw, used to fix a distal fibular fracture, that impinged on the distal tibial and causing symptoms. Awareness of the condition and early diagnosis based on thoughtful review of CT images are key to symptom alleviation. A review of the published data on the complication of "painful hardware" following ankle fracture fixation is also presented. PMID- 29172013 TI - The association between brain activity and motor imagery during motor illusion induction by vibratory stimulation. AB - BACKGROUND: The association between motor imagery ability and brain neural activity that leads to the manifestation of a motor illusion remains unclear. OBJECTIVE: In this study, we examined the association between the ability to generate motor imagery and brain neural activity leading to the induction of a motor illusion by vibratory stimulation. METHODS: The sample consisted of 20 healthy individuals who did not have movement or sensory disorders. We measured the time between the starting and ending points of a motor illusion (the time to illusion induction, TII) and performed electroencephalography (EEG). We conducted a temporo-spatial analysis on brain activity leading to the induction of motor illusions using the EEG microstate segmentation method. Additionally, we assessed the ability to generate motor imagery using the Japanese version of the Movement Imagery Questionnaire-Revised (JMIQ-R) prior to performing the task and examined the associations among brain neural activity levels as identified by microstate segmentation method, TII, and the JMIQ-R scores. RESULTS: The results showed four typical microstates during TII and significantly higher neural activity in the ventrolateral prefrontal cortex, primary sensorimotor area, supplementary motor area (SMA), and inferior parietal lobule (IPL). Moreover, there were significant negative correlations between the neural activity of the primary motor cortex (MI), SMA, IPL, and TII, and a significant positive correlation between the neural activity of the SMA and the JMIQ-R scores. CONCLUSION: These findings suggest the possibility that a neural network primarily comprised of the neural activity of SMA and M1, which are involved in generating motor imagery, may be the neural basis for inducing motor illusions. This may aid in creating a new approach to neurorehabilitation that enables a more robust reorganization of the neural base for patients with brain dysfunction with a motor function disorder. PMID- 29172016 TI - Applicability of simplified computational models in prediction of peak wall stress in abdominal aortic aneurysms. AB - In the paper impact of different material models on the calculated peak wall stress (PWS) and peak wall rupture risk (PWRR) in abdominal aortic aneurysms (AAAs) is assessed. Computational finite element models of 70 patient-specific AAAs were created using two different material models - a realistic one based on mean population results of uniaxial tests of AAA wall considered as reference, and a 100 times stiffer artificial model. The calculated results of PWS and PWRR were tested to evaluate statistical significance of differences caused by the non realistic material model. It was shown that for majority of AAAs the differences are insignificant but for some 10% of them their relative differences exceed 20% which may lead to incorrect decisions on their surgical treatment. This percentage of failures favours application of realistic material models in clinical practise although they are much more time-consuming. PMID- 29172018 TI - Are vaginal estrogens effective for preventing urinary tract infection in postmenopausal women? AB - INTRODUCTION: Urinary tract infection commonly affects postmenopausal women, probably because of the changes in vaginal flora secondary to estrogen deficiency. So, the use of vaginal estrogens could revert this process and then decrease the risk of infection. However, it is not clear whether they are really effective. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified seven systematic reviews including four primary studies overall and all were randomized trials. We concluded it is not clear whether vaginal estrogens decrease the risk of symptomatic urinary infection because the certainty of the available evidence is very low. PMID- 29172017 TI - Scutellarin Prevents Nonalcoholic Fatty Liver Disease (NAFLD) and Hyperlipidemia via PI3K/AKT-Dependent Activation of Nuclear Factor (Erythroid-Derived 2)-Like 2 (Nrf2) in Rats. AB - BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is a condition characterized by excessive fat accumulation in the form of triglycerides. The incidence of NAFLD and hyperlipidemia, with their associated risks of end-stage liver and cardiovascular diseases, is increasing rapidly. This study aimed to investigate the effects of scutellarin on the experimental NAFLD in high-fat diet fed and chronic stress rats, and its possible mechanism. MATERIAL AND METHODS Sprague Dawley rats were fed with high-fat diet and subjected to chronic stress for 12 weeks, and administered orally with scutellarin for 4 weeks (n=8), and then blood and livers were harvested for analyzing. Enzyme activity assay, immunofluorescence, Western blot, and quantitative RT-PCR were performed to analyze the factors of the oxidant/antioxidant system and pathway. RESULTS After the high-fat diet and chronic stress administration for 12 weeks, serum and liver lipid metabolism of treatment groups with the different doses of SCU effectively improved and the degree of oxidative damage reduced. Using Western blot assay and immunofluorescence (IF) staining assay, Nrf2, HO-1, and PI3K, and AKT proteins significantly increased after SCU treatment for 4 weeks (P<0.01). The hepatic mRNA expression of HO-1, NQO1, and Nrf2 in SCU treatment groups was upregulated significantly through quantitative RT-PCR assay (P<0.05). However, compared to the positive control group, no difference was detected in the SCU (100 or 300 mg/kg) groups (P>0.05). These results indicate that SCU protects against NAFLD in rats via attenuation of oxidative stress. CONCLUSIONS The antioxidant effects of SCU on NAFLD are possibly dependent on PI3K/AKT activation with subsequent Nrf2 nuclear translocation, which increases expression of HO-1 and NQO1. We therefore suggest that breviscapine may be a potentially useful therapeutic strategy for NAFLD and hyperlipidemia. PMID- 29172019 TI - The Long-Term Stability of KO2 in K-O2 Batteries. AB - The rechargeable K-O2 battery is recognized as a promising energy storage solution owing to its large energy density, low overpotential, and high coulombic efficiency based on the single-electron redox chemistry of potassium superoxide. However, the reactivity and long-term stability of potassium superoxide remains ambiguous in K-O2 batteries. Parasitic reactions are explored and the use of ion chromatography to quantify trace amounts of side products is demonstrated. Both quantitative titrations and differential electrochemical mass spectrometry confirm the highly reversible single-electron transfer process, with 98 % capacity attributed to the formation and decomposition of KO2 . In contrast to the Na-O2 counterparts, remarkable shelf-life is demonstrated for K-O2 batteries owing to the thermodynamic and kinetic stability of KO2 , which prevents the spontaneous disproportionation to peroxide. This work sheds light on the reversible electrochemical process of K+ +e- +O2 <->KO2 . PMID- 29172020 TI - Evaluation of the effect of different post materials and adhesive systems on the bonding strength of short-post technique for primary teeth. AB - BACKGROUND: The most important process in treating grossly decayed teeth, including decay in the pulp, is the ability to hold a retainer in for a short time. AIM: The aim of this study was to investigate the bond strengths of different adhesive systems and post materials on primary teeth. DESIGN: One hundred and twenty extracted maxillar primary central incisor teeth were randomly divided into two main groups (total-etch and self-etch adhesive systems) and five subgroups (1: control-nanohybrid composite resin, 2: pre-impregnated glass fiber, 3: unsaturated glass fiber, 4: polyethylene fiber, 5: short-fiber reinforced composite resin). The push-out test was performed using a universal testing machine with a crosshead speed of 0.5 mm/min. RESULTS: No statistically significant difference was detected between the two different adhesive systems and five different materials in terms of the maximum values measured for fractures in the specimens when both the adhesive materials and the short-post materials were evaluated separately (P > 0.05). However, as a result of multiple comparisons made, it was found that statistical differences between the groups applying the total-etch adhesive system occurred in Groups 3 and 5. The highest push-out test values were measured in Group 5 and Group 1, and the lowest value in Group 3. Although the fracture type distribution in the total-etch adhesive system groups was not statistically different based on the material used (chi2 = 11,865; P = 0.309), the self-etch adhesive systems did show differences (chi2 = 28,463; P < 0.001). Both the total-etch and the self-etch adhesive system groups showed mostly adhesive failures. CONCLUSION: The fiber-reinforced and nanohybrid composite resin had higher values in the short-post technique, and there was no significant difference between the different fiber posts. PMID- 29172021 TI - Early-onset type 2 diabetes: Age gradient in clinical and behavioural risk factors in 5115 persons with newly diagnosed type 2 diabetes-Results from the DD2 study. AB - AIM: To examine the association between early onset of type 2 diabetes mellitus (DM) and clinical and behavioural risk factors for later complications of diabetes. METHODS: We conducted a cross-sectional study of 5115 persons with incident type 2 DM enrolled during 2010-2015 in the Danish Centre for Strategic Research in Type 2 Diabetes-cohort. We compared risk factors at time of diagnosis among those diagnosed at <=45 years (early onset) with diagnosis age 46 to 55, 56 to 65 (average onset = reference), 66 to 75, and >75 years (late onset). Prevalence ratios (PRs) were computed by using Poisson regression. RESULTS: Poor glucose control, ie, HbA1c >= 75 mmol/mol (>=9.0%) in the early-, average-, and late-onset groups was observed in 12%, 7%, and 1%, respectively (PR 1.70 [95% confidence intervals (CI) 1.27, 2.28] and PR 0.17 [95% CI 0.06, 0.45]). A similar age gradient was observed for severe obesity (body mass index > 40 kg/m2 : 19% vs. 8% vs. 2%; PR 2.41 [95% CI 1.83, 3.18] and 0.21 (95% CI 0.08, 0.57]), dyslipidemia (90% vs. 79% vs. 68%; PR 1.14 [95% CI 1.10, 1.19] and 0.86 [95% CI 0.79, 0.93]), and low-grade inflammation (C-reactive protein > 3.0 mg/L: 53% vs. 38% vs. 26%; PR 1.41 [95% CI 1.12, 1.78] and 0.68 [95% CI 0.42, 1.11]). Daily smoking was more frequent and meeting physical activity recommendations less likely in persons with early-onset type 2 DM. CONCLUSIONS: We found a clear age gradient, with increasing prevalence of clinical and behavioural risk factors the younger the onset age of type 2 DM. Younger persons with early-onset type 2 DM need clinical awareness and support. PMID- 29172022 TI - Structure-Activity Relationships for Pt-Free Metal Phosphide Hydrogen Evolution Electrocatalysts. AB - In the field of renewable energy, the splitting of water into hydrogen and oxygen fuel gases using water electrolysis is a prominent topic. Traditionally, these catalytic processes have been performed by platinum-group metal catalysts, which are effective at promoting water electrolysis but expensive and rare. The search for an inexpensive and Earth-abundant catalyst has led to the development of 3d transition-metal phosphides for the hydrogen evolution reaction. These catalysts have shown excellent activity and stability. In this review, we discuss the electronic and crystal structures of bulk and surface of selected Fe, Co, and Ni phosphides, and their relationships to the experimental catalytic activity. The various synthetic protocols towards the state-of-the-art transition metal phosphide electrocatalysts are also discussed. PMID- 29172023 TI - Investigations of the local distortions and EPR parameters for Cu2+ in xNa2 O-(30 x)K2 O-70B2 O3 (5 <= x <= 25 mol%) glasses. AB - The local distortions and electron paramagnetic resonance parameters for Cu2+ in the mixed alkali borate glasses xNa2 O-(30-x)K2 O-70B2 O3 (5 <= x <= 25 mol%) are theoretically studied with distinct modifier Na2 O compositions x. Owing to the Jahn-Teller effect, the octahedral [CuO6 ]10- clusters show significant tetragonal elongation ratios p ~19% along the C4 axis. With the increase of composition x, the cubic field parameter Dq and the orbital reduction factor k exhibit linearly and quasi-linearly decreasing tendencies, respectively, whereas the relative tetragonal elongation ratio p has quasi-linearly increasing rule with some fluctuations, leading to the minima of g factors at x = 10 mol%. The composition dependences of the optical spectra and the electron paramagnetic resonance parameters are suitably reproduced by the linear or quasi-linear relationships of the relevant quantities (i.e., Dq, k, and p) with x. The above composition dependences are analyzed from mixed alkali effect, which brings forward the modifications of the local crystal-fields and the electronic cloud distribution around Cu2+ with the variation of the composition of Na2 O.

AB - Several studies have suggested a favorable role for vitamin D in glycaemic metabolism and its potential as adjuvant treatment of type 2 diabetes mellitus. This review discusses the role of vitamin D in the glycaemic control of individuals with type 2 diabetes mellitus and evaluates the effect of vitamin D supplementation on glycaemic markers in this population. Literature searches were performed in the BIREME, LILACS, and PubMed databases using the Medical Subject Headings and words related to vitamin D, type 2 diabetes mellitus, and glycaemic control. Interventional and observational studies were considered eligible. The evaluation of the included studies was independently performed by 2 evaluators at all stages of selection, data extraction, and bias risk assessment. The primary outcome was the relationship between vitamin D levels and glucose metabolism markers in type 2 diabetes mellitus individuals. The secondary outcome was the effect of vitamin D supplementation on the glycaemic control markers in individuals with type 2 diabetes mellitus. The inverse relationship between vitamin D and variables of glucose metabolism was verified. Interventional studies revealed that vitamin D supplementation did not alter glycaemic control markers in most studies. Few studies have shown positive effects with a significant reduction in the percentage of glycated haemoglobin, insulin, and glucose concentrations, and changes in homeostatic model assessment-insulin resistance and beta cell, and quantitative insulin sensitivity check index. Therefore, despite the association of vitamin D with glucose metabolism, there is insufficient evidence of the beneficial effects of its supplementation on the metabolic control of type 2 diabetes mellitus. PMID- 29172026 TI - Effect of non-prohibited drugs on the phase II metabolic profile of morphine. An in vitro investigation for doping control purposes. AB - The potential consequences of drug-drug interaction on the strategies adopted by anti-doping laboratories to report an adverse analytical finding for morphine were investigated. We evaluated in vitro the effects of 14 drugs on the principal metabolic pathways of morphine. The selected drugs are among those most commonly used by the athletes, none of them presently included in the World Anti-Doping Agency (WADA) Prohibited List. The non-prohibited drugs included 4 antifungals (fluconazole, itraconazole, ketoconazole, and miconazole), 6 benzodiazepines (alprazolam, bromazepam, clonazepam, lorazepam, lormetazepam, and triazolam), and 4 non-steroidal anti-inflammatory drugs (diclofenac, ibuprofen, ketoprofen, and nimesulide). The in vitro assays were based on the use of either human liver microsomes or uridine 5'-diphospho-glucuronosyl-transferases. Morphine and its glucuronides were determined by developed liquid chromatography-mass spectrometry procedure after dilution with an aqueous solution containing their deuterated isotopologues as internal standards. Morphine is mainly excreted as phase II metabolites: about 70% of the parent compound is found to be biotransformed by UGT2B7 to morphine-3-glucuronide (6065%) and morphine-6-glucuronide (5-10%). A reduction of the enzymatic activity of the UGT2B7 was recorded in the presence of 9 of the 14 drugs under investigation (ketoconazole, miconazole, itraconazole, diclofenac, ibuprofen, clonazepam, lorazepam, lormetazepam, and triazolam), with a consequent significant reduction of the levels of the glucuronide metabolites. This phenomenon in vivo may affect the rate of the urinary excretion of morphine with the risk of reporting "false negative" results, especially in case of results close to the decision limit value set by WADA. PMID- 29172027 TI - An enhanced chemoenzymatic method for loading substrates onto carrier protein domains. AB - Non-ribosomal peptide synthetase (NRPS) machineries produce many medically relevant peptides that cannot be easily accessed by chemical synthesis. Thus, understanding NRPS mechanism is of crucial importance to allow efficient redesign of these machineries to produce new compounds. During NRPS-mediated synthesis, substrates are covalently attached to peptidyl carrier proteins (PCPs), and studies of NRPSs are impeded by difficulties in producing PCPs loaded with substrates. Different approaches to load substrates onto PCP domains have been described, but all suffer from difficulties in either the complexity of chemical synthesis or low enzymatic efficiency. Here, we describe an enhanced chemoenzymatic loading method that combines 2 approaches into a single, highly efficient one-pot loading reaction. First, d-pantetheine and ATP are converted into dephospho-coenzyme A via the actions of 2 enzymes from coenzyme A (CoA) biosynthesis. Next, phosphoadenylates are dephosphorylated using alkaline phosphatase to allow linker attachment to PCP domain by Sfp mutant R4-4, which is inhibited by phosphoadenylates. This route does not depend on activity of the commonly problematic dephospho-CoA kinase and, therefore, offers an improved method for substrate loading onto PCP domains. PMID- 29172028 TI - Neural adaptations in quadriceps muscle after 4 weeks of local vibration training in young versus older subjects. AB - This study investigated the effects of a 4-week local vibration training (LVT) on the function of the knee extensors and corticospinal properties in healthy young and older subjects. Seventeen subjects (9 young and 8 older) performed 3 testing sessions: before (PRE1) and after (PRE2) a 4-week resting period to control the repeatability of the data as well as after the LVT (POST). Jump performance, maximal voluntary contraction (MVC) and electromyographic (EMG) activity on vastus lateralis and rectus femoris muscles were assessed. Single-pulse transcranial magnetic stimulation (TMS) allowed evaluation of cortical voluntary activation (VATMS), motor evoked potential (MEP) area, and silent period (SP) duration. All training adaptations were similar between young and older subjects (p > 0.05) and the following results reflect the pooled sample of subjects. MVC (+11.9% +/- 8.0%, p < 0.001) and VATMS (+3.6% +/- 5.2%, p = 0.004) were significantly increased at POST compared with PRE2. Maximal vastus lateralis EMG was significantly increased at POST (+21.9% +/- 33.7%, p = 0.03). No changes were reported for MEPs on both muscles (p > 0.05). SPs recorded during maximal and submaximal contractions decreased in both muscles at POST (p < 0.05). Vertical jump performance was increased at POST (p < 0.05). LVT seems as effective in young as in older subjects to improve maximal functional capacities through neural modulations occurring at least partly at the supra-spinal level. Local vibration may be used as an efficient alternative training method to improve muscular performance in both healthy young and older subjects. PMID- 29172029 TI - Decreasing sprint duration from 20 to 10 s during reduced-exertion high-intensity interval training (REHIT) attenuates the increase in maximal aerobic capacity but has no effect on affective and perceptual responses. AB - Recent studies have demonstrated that modifying the "classic" 6 * 30-s "all-out" sprint interval training protocol by incorporating either shorter sprints (6 * 10 s or 15-s sprints) or fewer sprints (e.g., 2 * 20-s sprints; reduced-exertion high-intensity interval training (REHIT)) does not attenuate the training-induced improvements in maximal aerobic capacity. The aim of the present study was to determine if reducing the sprint duration in the REHIT protocol from 20 s to 10 s per sprint influences acute affective responses and the change in maximal aerobic capacity following training. Thirty-six sedentary or recreationally active participants (17 women; mean +/- SD; age: 22 +/- 3 years; body mass index: 24.5 +/- 4.6 kg.m-2; maximal aerobic capacity: 37 +/- 8 mL.kg-1.min-1) were randomised to a group performing a "standard" REHIT protocol involving 2 * 20-s sprints or a group who performed 2 * 10-s sprints. Maximal aerobic capacity was determined before and after 6 weeks of 3 weekly training sessions. Acute affective responses and perceived exertion were assessed during training. Greater increases in maximal aerobic capacity were observed for the group performing 20-s sprints (2.77 +/- 0.75 to 3.04 +/- 0.75 L.min-1; +10%) compared with the group performing 10-s sprints (2.58 +/- 0.57 vs. 2.67 +/- 3.04 L.min-1; +4%; group * time interaction effect: p < 0.05; d = 1.06). Positive affect and the mood state vigour increased postexercise, while tension, depression, and total mood disturbance decreased, and negative affect remained unchanged. Affective responses and perceived exertion were not altered by training and were not different between groups. In conclusion, reducing sprint duration in the REHIT protocol from 20 s to 10 s attenuates improvements in maximal aerobic capacity, and does not result in more positive affective responses or lower perceived exertion.

PMID- 29172031 TI - Close Resection Margins Do Not Influence Local Recurrence in Patients With Oral Squamous Cell Carcinoma: A Prospective Cohort Study. AB - PURPOSE: This study investigated the clinical relevance of the distance between the resection margin and tumor cells of the primary sites for oral squamous cell carcinoma, with particular attention to local recurrence rate. PATIENTS AND METHODS: All patients diagnosed with oral squamous cell carcinoma from 1995 to 2006 and treated primarily with surgery formed the initial cohort of the study. Patient with various degrees of dysplasia in the margin, patients who received radiotherapy, and patients who died of causes other than oral cancer were excluded. Margins 1 to 5 mm were considered close. A margin of at least 5 mm was considered free of disease (clear). Local recurrence was defined as tumor development at the site of the primary tumor during the follow-up period (>=5 yr). The Fisher exact test was used to determine the relevance of the differences between the studied groups (free vs close margins) in relation to local recurrence. RESULTS: Histologic analysis of the specimens was performed. Of the 53 patients, 32 had free margins and 3 of the 32 had a local recurrence. In addition, 21 patients had close margins and 3 of the 21 had a local recurrence. The difference between the 2 groups was not statistically relevant. CONCLUSIONS: The authors advocate that the strategy of using close resection margins as a generic indicator for local recurrence and adverse prognosis might have to be reassessed. The histopathologic evidence of tumor cells within a distance less than 0.5 cm from the surgical margins does not necessarily seem to offer a certain indication for additional treatment. Other prognostic factors, such as involvement of cervical lymph nodes and tumor depth, must be considered in the decision making for further treatment.

AB - INTRODUCTION: Invasive aspergillosis is a condition associated with a high mortality rate mostly due to difficulties in performing an early diagnosis. In recent years, galactomannan detection has markedly improved the diagnosis of invasive aspergillosis, but very little is known on how physicians deal with this test in clinical practice. METHODS: This cross-sectional study aimed to analyze the indications for the use of serum galactomannan in a large Brazilian hospital, between 2015 and 2016. No specific protocol was in place for GM request. We reviewed the medical records of adult (>18 years-old) patients who were tested for galactomannan due to one the following indications: screening, diagnosis, or treatment follow-up. Additional variables included demographic data, underlying diseases, presence of neutropenia, and use of previous antifungal (anti Aspergillus) drugs. RESULTS: The mean age of the patients was 51 years-old (sd+/ 15.8), and 63.3% of patients were male. Patients with hematological malignancies accounted for 60.1% of the cases, mostly acute myeloid leukemia (19.6%). Galactomannan testing was positive in 12.2% of patients, including 1.6% of occasions in which the test was used for screening purposes, 13.2% for diagnosis, and 32.4% during follow-up. Median time for chest imaging request was two days before GM testing. Previous antifungal therapy was reported for 35.1% of patients, mostly amphotericin B (57.1%). CONCLUSION: The correct use of galactomannan testing is essential for an early diagnosis of invasive aspergillosis, which may improve the prognosis of the disease. We demonstrated that clinicians usually ask for galactomannan tests to confirm imaging findings in patients who frequently were on antifungal drugs, something that could be improved by medical education. We observed a low frequency of galactomannan use for preemptive antifungal therapy (25.7%), which is worrying considering the well known beneficial use of GM testing in this scenario. PMID- 29172033 TI - In vitro antifungal susceptibility of clinical and environmental isolates of Aspergillus fumigatus and Aspergillus flavus in Brazil. AB - The in vitro susceptibility of 105 clinical and environmental strains of Aspergillus fumigatus and Aspergillus flavus to antifungal drugs, such as amphotericin B, azoles, and echinocandins was evaluated by the broth microdilution method proposed by the European Committee on Antimicrobial Susceptibility Testing (EUCAST). Following the EUCAST-proposed breakpoints, 20% and 25% of the clinical and environmental isolates of A. fumigatus, respectively, were found to be resistant to itraconazole (Minimal Inhibitory Concentration, MIC>2.0mg/L). Voriconazole showed good activity against A. fumigatus and A. flavus strains, except for one clinical strain of A. fumigatus whose MIC was 4.0mg/L. Posaconazole (<=0.25mg/L) also showed appreciable activity against both species of Aspergillus, except for six A. fumigatus strains with relatively higher MICs (0.5mg/L). The MICs for Amphotericin B ranged from 0.06 to 1.0mg/L for A. fumigatus, but were much higher (0.5-8.0mg/L) for A. flavus. Among the echinocandins, caspofungin showed a geometric mean of 0.078 and 0.113 against the clinical and environmental strains of A. flavus, respectively, but had elevated minimal effective concentrations (MECs) for seven of the A. fumigatus strains. Anidulafungin and micafungin exhibited considerable activity against both A. fumigatus and A. flavus isolates, except for one environmental isolate of A. fumigatus that showed an MEC of 1mg/L to micafungin. Our study proposes that a detailed investigation of the antifungal susceptibility of the genus Aspergillus from different regions of Brazil is necessary for establishing a response profile against the different classes of antifungal agents used in the treatment of aspergillosis. PMID- 29172034 TI - Development of mannose functionalized dendrimeric nanoparticles for targeted delivery to macrophages: use of this platform to modulate atherosclerosis. AB - Dysfunctional macrophages underlie the development of several diseases including atherosclerosis where accumulation of cholesteryl esters and persistent inflammation are 2 of the critical macrophage processes that regulate the progression as well as stability of atherosclerotic plaques. Ligand-dependent activation of liver-x-receptor (LXR) not only enhances mobilization of stored cholesteryl ester but also exerts anti-inflammatory effects mediated via trans repression of proinflammatory transcription factor nuclear factor kappa B. However, increased hepatic lipogenesis by systemic administration of LXR ligands (LXR-L) has precluded their therapeutic use. The objective of the present study was to devise a strategy to selectively deliver LXR-L to atherosclerotic plaque associated macrophages while limiting hepatic uptake. Mannose-functionalized dendrimeric nanoparticles (mDNP) were synthesized to facilitate active uptake via the mannose receptor expressed exclusively by macrophages using polyamidoamine dendrimer. Terminal amine groups were used to conjugate mannose and LXR-L T091317 via polyethylene glycol spacers. mDNP-LXR-L was effectively taken up by macrophages (and not by hepatocytes), increased expression of LXR target genes (ABCA1/ABCG1), and enhanced cholesterol efflux. When administered intravenously to LDLR-/- mice with established plaques, significant accumulation of fluorescently labeled mDNP-LXR-L was seen in atherosclerotic plaque-associated macrophages. Four weekly injections of mDNP-LXR-L led to significant reduction in atherosclerotic plaque progression, plaque necrosis, and plaque inflammation as assessed by expression of nuclear factor kappa B target gene matrix metalloproteinase 9; no increase in hepatic lipogenic genes or plasma lipids was observed. These studies validate the development of a macrophage-specific delivery platform for the delivery of anti-atherosclerotic agents directly to the plaque-associated macrophages to attenuate plaque burden.

AB - OBJECTIVE: To evaluate television and simultaneous electronic devices use in adolescents with musculoskeletal pain and musculoskeletal pain syndromes. METHODS: A cross-sectional study was performed in 299 healthy adolescents of a private school. All students completed a self-administered questionnaire, including: demographic data, physical activities, musculoskeletal pain symptoms, and use of simultaneous television/electronic devices (computer, internet, electronic games, and cell phones). Seven musculoskeletal pain syndromes were also evaluated: juvenile fibromyalgia, benign joint hypermobility syndrome, myofascial syndrome, tendinitis, bursitis, epicondylitis, and complex regional pain syndrome. RESULTS: Inter-rater agreement between pretest and retest was 0.83. Musculoskeletal pain and musculoskeletal pain syndrome were found in 183/299 (61%) and 60/183 (33%), respectively. The median age (15 [10-18] vs. 14 [10-18] years, p=0.032) and years of education (10 [5-12] vs. 9 [5-12] years, p=0.011) were significantly higher in adolescents with musculoskeletal pain when compared with those without this condition. The frequencies of female gender (59% vs. 47%, p=0.019), cell phone use (93% vs. 81%, p=0.003), and simultaneous use of at least two electronic devices (80% vs. 67%, p=0.011) were significantly higher in the former group. Further comparisons between adolescents with and without musculoskeletal pain syndromes revealed that the frequency of female gender was significantly higher in the former group (75% vs. 25%, p=0.002), and with a significantly reduced median of weekends/holidays electronic games use (1.5 [0 10] vs. 3 [0-17]h/day, p=0.006). CONCLUSIONS: A high prevalence of musculoskeletal pain/syndromes was observed in female adolescents. Musculoskeletal pain was mostly reported at a median age of 15 years, and students used at least two electronic devices. Reduced use of electronic games was associated with musculoskeletal pain syndromes. PMID- 29172035 TI - Macrophages under pressure: the role of macrophage polarization in hypertension. AB - Hypertension is a multifactorial disease involving the nervous, renal, and cardiovascular systems. Macrophages are the most abundant and ubiquitous immune cells, placing them in a unique position to serve as key mediators between these components. The polarization of macrophages confers vast phenotypic and functional plasticity, allowing them to act as proinflammatory, homeostatic, and anti-inflammatory agents. Key differences between the M1 and M2 phenotypes, the 2 subsets at the extremes of this polarization spectrum, place macrophages at a juncture to mediate many mechanisms involved in the pathogenesis of hypertension. Neuronal and non-neuronal regulation of the immune system, that is, the "neuroimmuno" axis, plays an integral role in the polarization of macrophages. In hypertension, the neuroimmuno axis results in synchronization of macrophage mobilization from immune cell reservoirs and their chemotaxis, via increased expression of chemoattractants, to end organs critical in the development of hypertension. This complicated system is largely coordinated by the dichotomous actions of the autonomic neuronal and non-neuronal activation of cholinergic, adrenergic, and neurohormonal receptors on macrophages, leading to their ability to "switch" between phenotypes at sites of active inflammation. Data from experimental models and human studies are in concordance with each other and support a central role for macrophage polarization in the pathogenesis of hypertension. PMID- 29172039 TI - Health-related quality of life in patients with bronchiolitis obliterans. AB - OBJECTIVE: To evaluate the overall health-related quality of life in patients with bronchiolitis obliterans. METHODS: Participants with a diagnosis of post infectious bronchiolitis obliterans, who were being followed-up at two specialized outpatient clinics of Pediatric Pulmonology in Porto Alegre, Brazil, and controls aged between 8 and 17 years, of both genders, were included in the study. Controls were paired by gender, age, and socioeconomic level in relation to the group of participants with post-infectious bronchiolitis obliterans. The version of the Pediatric Quality of Life Inventory (PedsQ) tool validated for Brazil was applied for the assessment of Health-related Quality of Life, through an interview. The comparison of the Health-related Quality of Life means between the groups was performed using Student's t-test for independent samples and the chi-squared test, for categorical variables. RESULTS: 34 patients diagnosed with post-infectious bronchiolitis obliterans and 34 controls participated in the study. The mean age of the children included in the study was 11.2+/-2.5 years, and 49 (72%) of them were males. The groups showed no significant differences in relation to these variables. The quality of life score was significantly and clinically lower in the post-infectious bronchiolitis obliterans group when compared with controls in the health (72.36+/-15.6, 81.06+/-16.4, p=0.031) and school domains (62.34+/-20.7, 72.94+/-21.3, p=0.043), as well as in the total score (69.53+/-14.9, 78.02+/-14.8, p=0.024), respectively. CONCLUSION: Patients with post-infectious bronchiolitis obliterans presented lower health-related quality of life scores when compared with healthy individuals in the total score and in the health and school domains. PMID- 29172040 TI - Effect of long-term fertilization on humic redox mediators in multiple microbial redox reactions. AB - This study investigated the effects of different long-term fertilizations on humic substances (HSs), humic acids (HAs) and humins, functioning as redox mediators for various microbial redox biotransformations, including 2,2',4,4',5,5'- hexachlorobiphenyl (PCB153) dechlorination, dissimilatory iron reduction, and nitrate reduction, and their electron-mediating natures. The redox activity of HSs for various microbial redox metabolisms was substantially enhanced by long-term application of organic fertilizer (pig manure). As a redox mediator, only humin extracted from soils with organic fertilizer amendment (OF HM) maintained microbial PCB153 dechlorination activity (1.03 MUM PCB153 removal), and corresponding HA (OF-HA) most effectively enhanced iron reduction and nitrate reduction by Shewanella putrefaciens. Electrochemical analysis confirmed the enhancement of their electron transfer capacity and redox properties. Fourier transform infrared analysis showed that C=C and C=O bonds, and carboxylic or phenolic groups in HSs might be the redox functional groups affected by fertilization. This research enhances our understanding of the influence of anthropogenic fertility on the biogeochemical cycling of elements and in situ remediation ability in agroecosystems through microorganisms' metabolisms. PMID- 29172041 TI - Airborne microplastics: Consequences to human health? AB - Microplastics have recently been detected in atmospheric fallout in Greater Paris. Due to their small size, they can be inhaled and may induce lesions in the respiratory system dependent on individual susceptibility and particle properties. Even though airborne microplastics are a new topic, several observational studies have reported the inhalation of plastic fibers and particles, especially in exposed workers, often coursing with dyspnea caused by airway and interstitial inflammatory responses. Even though environmental concentrations are low, susceptible individuals may be at risk of developing similar lesions. To better understand airborne microplastics risk to human health, this work summarizes current knowledge with the intention of developing awareness and future research in this area. PMID- 29172042 TI - The transformation of triclosan by laccase: Effect of humic acid on the reaction kinetics, products and pathway. AB - This study systematically explored the effect of humic acid (HA) (as model of natural organic matter) on the kinetics, products and transformation pathway of triclosan (TCS) by laccase-catalyzed oxidation. It was found that TCS could be effectively transformed by laccase-catalysis, with the apparent second-order rate constant being 0.056 U-1 mL min-1. HA inhibited the removal rate of TCS. HA induced inhibition was negatively correlated with HA concentration in the range of 0-10 mg L-1 and pH-dependent from 3.5 to 9.5. FT-IR and 13C NMR spectra showed a decrease of aromatic hydroxyl (phenolic) groups and an increase of aromatic ether groups, indicating the cross-linking of HA via C-O-C and C-N-C bonds during enzyme-catalyzed oxidation. Ten principle oxidative products, including two quinone-like products (2-chlorohydroquinone, 2-chloro-5-(2,4 dichlodichlorophenoxy)-(1,4)benzoquinone), one chlorinated phenol (2,4 dichlorophenol (2,4-DCP)), three dimers, two trimmers and two tetramers, were detected by gas chromatograghy/mass spectrometry (GC-MS) and high performance liquid chromatography/quadrupole time-of-flight/mass spectrometry (HPLC/Q TOF/MS). The presence of HA induced significantly lesser generation of self polymers and enhanced cross-coupling between HA and self-polymers via C-O-C, C-N C and C-C coupling pathways. A plausible transformation pathway was proposed as follows: TCS was initially oxidized to form reactive phenoxyl radicals, which self-coupled to each other subsequently by C-C and C-O pathway, yielding self polymers. In addition, the scission of ether bond was also observed. The presence of HA can promote scission of ether bond and further oxidation of phenoxyl radicals, forming hydroxylated or quinone-like TCS. This study shed light on the behavior of TCS in natural environment and engineered processes, as well provided a perspective for the water/wastewater treatment using enzyme-catalyzed oxidation techniques. PMID- 29172043 TI - Polycyclic aromatic hydrocarbons in fruits and vegetables: Origin, analysis, and occurrence. AB - Feed intake, for non-smokers, is the first route of contamination to polycyclic aromatic hydrocarbons (PAHs), which are potentially toxic compounds via ingestion. Investigations are focused on the presence of PAHs in fruits and vegetables. Transfer of PAHs can occur from air and soil during cultivation. They can also appear prior to consumption during storage, transport or cooking processes. Rather low amounts of PAHs are usually detected in raw fruits and vegetables. Quantities are between 0.01 and 0.5 MUg kg-1 (wet weight) for compounds classified as priority pollutants by the US Environmental Protection Agency (EPA). However, several studies point out that concentrations of some PAHs can exceed 0.5 MUg kg-1 wet weight in diverse fruits and vegetables and even reach 5 MUg kg-1. Amounts can be very different depending on the surrounding area of the crops, the aromatic hydrocarbon, or even the product itself. PAHs content is usually higher for products grown near roadways or in urban regions than in rural areas. Trace level of compounds such as phenanthrene, fluoranthene and pyrene have been found in quite every raw fruit and vegetable. Relative high amounts of lighter PAHs such as naphthalene, acenaphthylene, and acenaphthene have been found in some of them. PMID- 29172044 TI - Investigation on the wrong way driving crash patterns using multiple correspondence analysis. AB - Wrong way driving (WWD) has been a constant traffic safety problem in certain types of roads. Although these crashes are not large in numbers, the outcomes are usually fatalities or severe injuries. Past studies on WWD crashes used either descriptive statistics or logistic regression to determine the impact of key contributing factors. In conventional statistics, failure to control the impact of all contributing variables on the probability of WWD crashes generates bias due to the rareness of these types of crashes. Distribution free methods, such as multiple correspondence analysis (MCA), overcome this issue, as there is no need of prior assumptions. This study used five years (2010-2014) of WWD crashes in Louisiana to determine the key associations between the contribution factors by using MCA. The findings showed that MCA helps in presenting a proximity map of the variable categories in a low dimensional plane. The outcomes of this study are sixteen significant clusters that include variable categories like determined several key factors like different locality types, roadways at dark with no lighting at night, roadways with no physical separations, roadways with higher posted speed, roadways with inadequate signage and markings, and older drivers. This study contains safety recommendations on targeted countermeasures to avoid different associated scenarios in WWD crashes. The findings will be helpful to the authorities to implement appropriate countermeasures. PMID- 29172045 TI - Interactive risk analysis on crash injury severity at a mountainous freeway with tunnel groups in China. AB - Traffic safety of freeways has attracted major concerns, especially for a mountainous freeway affected by adverse terrain conditions, constrained roadway geometry and complicated driving environments. On the basis of a comprehensive dataset collected from a mountainous freeway with a length of 61km but gathering 12 tunnels, this study seeks to examining the interactive effect of mountainous freeway alignment, driving behaviors, vehicle characteristics and environmental factors on crash severity. A classification and regression tree (CART) model is employed as it can deal with high-order interactions between explanatory variables. Results show that the driving behavior is the most important determinant for injury severity of mountainous freeway crashes, followed by the crash time, grade, curve radius and vehicle type. These variables, interacted with the factors of season and crash location, may largely account for the likelihood of high risk events which may result in severe crashes. Events associated with a notably higher probability of severe crashes include coach drivers involved in improper lane changing and other improper actions, drivers involved in speeding during afternoon or evening, drivers involved in speeding along large curve and straight segment during morning, noon or night, and drivers involved in fatigue while passing along the downgrade. Safety interventions to prevent severe crashes at the mountainous freeway include hierarchical supervision in terms of hazardous driving events, enhanced enforcement for speeding and fatigue driving, deployment of advanced driving assistance systems for fatigue driving warning, and cumulative driving time monitoring for long distance-travel freight vehicles. PMID- 29172046 TI - Evaluating the effect of lane width and roadside configurations on speed, lateral position and likelihood of comfortable overtaking in exclusive motorcycle lane. AB - Construction of exclusive motorcycle lanes is one of the measures to reduce motorcycle fatalities. Previous studies highlighted the risk of crashes with roadside objects and the tendency of motorcyclists to ride with excessive speed on exclusive motorcycle lanes. However, the risk of same-direction crashes on exclusive motorcycle lanes was not explored in much detail, especially on the impact of lane geometry and roadside configurations. This study used naturalistic riding data to determine the effects of lane width and roadside configurations on overtaking speed, lateral position and likelihood of comfortable overtaking on tangential sections of an exclusive motorcycle lane. Twenty-nine recruited motorcyclists rode the instrumented motorcycles along a 20km stretch of an exclusive motorcycle lane along a major urban road. Results revealed that both the roadside configurations and lane width significantly affect the participants' lateral position, while the roadside configurations only affects the overtaking speed. Participants' overtaking speeds and the front motorcycles' lateral position contribute significantly to the likelihood of comfortable overtaking in exclusive motorcycle lanes. The findings highlight the importance of micro-level behavior indicators in improving the design and overall safety of the exclusive motorcycle facility. PMID- 29172047 TI - Unhealthy assimilation or persistent health advantage? A longitudinal analysis of immigrant health in the United States. AB - Existing evidence on immigrant health assimilation, which is largely based on cross-sectional data, suggests that immigrants' initial health advantage erodes over time. This study uses longitudinal data to directly compare the self-rated health trajectories of immigrants and the native-born population. Data come from four panels of the Survey of Income and Program Participation (1996, 2001, 2004, and 2008), with each panel containing 2-4 years of health information. Results show that immigrants' self-rated health remained stable during the period under study, but there was a concomitant decline in health for the native-born population. This result pointed to a persistent health advantage of immigrants during the period under study. The pattern held for immigrants of different length of residence and was especially salient for those originally from Latin America and Asia. Our findings that immigrants maintain their health advantage do not support the pattern of unhealthy assimilation commonly reported in cross sectional studies. PMID- 29172048 TI - Life events in schizoaffective disorder: A systematic review. AB - BACKGROUND: Life events play a central role in the development of psychiatric disorders and impact course and outcome. We present a systematic review of the literature on the relationship of life events with the onset and long-term course of schizoaffective disorder. METHODS: MEDLINE was searched with the combination of the key words: 'life events' plus 'schizoaffective'. The PRISMA method was followed in the review process. RESULTS: From the identified 66 papers only 12 were considered to be of relevance to the current study and 6 more papers were identified by inspecting the reference lists of the identified papers. LIMITATIONS: There are very few studies focusing on the role of life events in schizoaffective disorder indicating insufficient data concerning the relationship of life events with onset and long-term course of schizoaffective disorder. Reported effects are not generic but concern specific events like the loss of mother, and females seem to be more vulnerable. Patients with schizoaffective disorder manifest high rates of PTSD. CONCLUSION: The literature on life events with the development and course of schizoaffective disorder is limited and precludes solid conclusions. PMID- 29172049 TI - Emotion regulation strategies moderate the relationship of fatigue with depersonalization and derealization symptoms. AB - BACKGROUND: The aim of the present study was to investigate the relationships of common emotion regulation strategies (suppression and reappraisal) to self reported fatigue and depersonalization/derealization symptoms. Specifically, we tested the moderating effect of suppression and reappraisal on the link of fatigue with depersonalization and derealization symptoms. Opposite effects were expected for both emotion regulation strategies assuming that cognitive reappraisal has an adaptive buffering effect, while suppression intensifies the association of fatigue and depersonalization/derealization experiences. METHODS: In a representative study (N = 2524) we assessed emotion regulation strategies, fatigue, depersonalization/derealization, distress, and demographic variables via questionnaires. 55.5% of the participants were female, mean age was 49.4 (SD = 18.2) years with age groups represented in comparable proportions. RESULTS: In line with the assumptions, moderated regression analyses revealed an interaction effect of emotion regulation strategies and fatigue. Simple slope analyses indicated a buffering effect of cognitive reappraisal on the positive relation of fatigue with depersonalization and derealization symptoms. In contrast, suppression fosters the positive correlation of fatigue and depersonalization and derealization experiences. LIMITATIONS: Our study is limited to these two habitual emotion regulation strategies employing a cross sectional design. CONCLUSION: Our findings provide comprehensive empirical data investigating depersonalization/derealization symptoms from the perspective of emotion regulation research. Cognitive reappraisal might help people suffering from fatigue to prevent depersonalization and derealization tendencies. PMID- 29172050 TI - A longitudinal study of Latino and non-Hispanic mothers' and fathers' depressive symptoms and its association with parent-child communication. AB - BACKGROUND: Roughly 8% of the U.S. population report moderate or severe depression for two or more weeks and Latinos (3.7%) report higher rates of severe depression compared to non-Hispanic whites (2.6%) (Pratt and Brody, 2014). As the Latino population continues to grow in the U.S., there is little research on the manifestations for depression, and how this affects the family system longitudinally. METHODS: Based on data from the Fragile Families and Child Wellbeing Study, a 3-step latent class analysis examined the association of self reported parental depressive symptoms and their children's perceived levels of closeness and openness to communicate with their parents over 9 years (N=3956 families). RESULTS: Latino parents reported four different depressive patterns, while non-Hispanic parents were more diversified and had six patterns in terms of latent class analysis. Latinos reported episodic symptoms, while NH parents were more likely to report chronic depressive symptoms over time. Regardless of race/ethnicity, parental depressive symptoms negatively affected their children's reported level of parental closeness and openness to communicate with mothers and fathers. LIMITATIONS: As with any self-report data, the risk of social desirability bias is likely still present. Additionally, these results cannot be generalized to the broader U.S. POPULATION: CONCLUSIONS: Due to the different mental health presentations over 9 years, and following the federal initiatives (National Institute of Mental Health, 2015) of early and consistent surveillance, we advise that clinicians and primary care physicians screen for depressive symptoms at least yearly. PMID- 29172052 TI - Profiling risk for depressive disorder by circuit, behavior and self-report measures of emotion function. AB - BACKGROUND: Major depressive disorder (MDD) is characterized by maladaptions in affective brain circuitry and in emotion regulation. It remains unknown whether these maladaptions characterize first-degree relatives of probands who are unaffected yet have a higher risk of developing MDD. METHODS: Participants were 72 unaffected first-degree relatives of probands with MDD and 66 matched non relative controls. We investigated brain circuit function and self-reported emotion regulation strategies for reappraisal and suppression. During functional magnetic resonance imaging, we probed circuitry relevant to both negative and positive valence systems using facial expressions signaling potential threat, sadness and happiness, presented under both conscious and subliminal viewing conditions. We compared groups using a statistically controlled region of interest (ROI) approach including the amygdala, insula, anterior cingulate cortex (ACC), ventromedial prefrontal cortex and dorsolateral prefrontal cortex. We also used a data-driven cluster analytic approach for characterizing the relatives by their brain function profiles. RESULTS: As a group, relatives were distinguished by hyper-reactivity of the pregenual ACC during subliminal viewing of threat related expressions but hypo-activation of the amygdala, insula and dorsal ACC during explicit viewing of the same threat-related expressions and sadness. When considered individually, this brain function profile characterized two-thirds of relatives, and these relatives were also less likely to use reappraisal to regulate negative emotion. LIMITATIONS: The design was cross-sectional and therefore does not provide direct evidence as to the trait- (versus state-) like profile observed in relatives. CONCLUSIONS: Familial risk for MDD may involve a disruption to the normal recruitment of neural circuits for appraising salient emotions, both implicit and explicit. Interventions targeting reappraisal strategies for regulating negative emotion may serve to buffer this risk. PMID- 29172051 TI - DNA methylation from birth to late adolescence and development of multiple-risk behaviours. AB - BACKGROUND: Risk behaviours in adolescence are linked to poor educational attainment and health and other outcomes in young adulthood. We explored whether there are molecular mechanisms associated with the development, or the result, of multiple risk behaviours (MRBs). METHODS: MRBs (antisocial behaviour and delinquency, traffic-related risk behaviour, risky sexual behaviour, lack of exercise) and their sumscore were characterized based on self-reported questions at age 7 and 17 within the ARIES subsample of the ALSPAC birth cohort, and were linked to DNA methylation at over 485,000 CpG sites at ages 0,7 and 17. Associations were determined for participants with complete data (n = 227-575). RESULTS: There was weak evidence of associations between cumulative MRBs and methylation at cg01783492 and cg16720578 at age 17. DNA methylation at age 17 was associated with risky sexual behaviour (cg22883332), lack of exercise (cg03152353, cg20056908, cg20571116) and substance use (cg02188400, cg13906377). No associations between DNA methylation and individual risk behaviours at age 7 were observed. DNA methylation at age 7 might predispose for traffic-related risk behaviour (cg24683561) and substance use (cg08761410) at age 17. LIMITATIONS: Main limitations are absence of information on directly measured blood cell type proportions and tissue specificity, and a modest sample size. CONCLUSIONS: Cumulative MRB in late adolescence was associated with effects on DNA methylation. More specifically, risky sexual behaviour and sedentary behaviour are associated with changes in DNA methylation, while DNA methylation in childhood may predict later traffic-related risky behaviour. For substance use effects in both temporal directions were observed. PMID- 29172053 TI - Associations of neurofunctional, morphometric and metabolic abnormalities with clinical symptom severity and recognition deficit in obsessive-compulsive disorder. AB - BACKGROUND: Obsessive-compulsive disorder (OCD) causes neural dysfunction associated with cognitive deficit and emotional dysregulation. This study assessed the associations of the neurofunctional changes, gray matter (GM) and white matter (WM) volume alterations in conjunction with in vivo metabolic changes on the working memory tasks in patients with OCD. METHODS: Eighteen patients with OCD and 18 healthy controls matched for age, sex, and educational levels underwent high-resolution T1-weighted magnetic resonance imaging (MRI), event-related functional MRI (fMRI), and proton magnetic resonance spectroscopy (1H-MRS) at 3T. RESULTS: In fMRI, patients with OCD showed lower activities in the cerebellum, inferior temporal gyrus, orbitofrontal gyrus, dorsolateral prefrontal cortex and calcarine gyrus compared to the controls. In VBM, the patients showed significantly reduced GM volumes, especially in the cerebellum, hippocampus, and superior temporal gyrus, together with significantly reduced WM volumes in the retrolenticular part of the internal capsule, dorsolateral prefrontal cortex (DLPFC) and orbitofrontal gyrus. In 1H-MRS, the ratios of N acetylaspartate/creatine and choline/creatine were significantly lower in the DLPFC of the patients than in the controls, whereas the ratio of beta?gamma glutamine-glutamate/creatine was significantly higher in the patients than in the controls. LIMITATIONS: This study examined small numbers of subjects in each one of the groups. CONCLUSIONS: The findings will be helpful to aid us in understanding of neurocognitive impairment in OCD, and thus, enhancing the diagnostic accuracy for OCD by additional information on the associated brain functional deficit, cerebral volume change and metabolic abnormality. PMID- 29172054 TI - Mobile technology for medication adherence in people with mood disorders: A systematic review. AB - BACKGROUND: Medication non-adherence is a critical challenge for many patients diagnosed with mood disorders (Goodwin and Jamison, 1990). There is a need for alternative strategies that improve adherence among patients with mood disorders that are cost-effective, able to reach large patient populations, easy to implement, and that allow for communication with patients outside of in-person visits. Technology-based approaches to promote medication adherence are increasingly being explored to address this need. The aim of this paper is to provide a systematic review of the use of mobile technologies to improve medication adherence in patients with mood disorders. METHODS: A total of nine articles were identified as describing mobile technology targeting medication adherence in mood disorder populations. RESULTS: Results showed overall satisfaction and feasibility of mobile technology, and reduction in mood symptoms; however, few examined effectiveness of mobile technology improving medication adherence through randomized control trials. LIMITATIONS: Given the limited number of studies, further research is needed to determine long term effectiveness. CONCLUSIONS: Mobile technologies has the potential to improve medication adherence and can be further utilized for symptom tracking, side effects tracking, direct links to prescription refills, and provide patients with greater ownership over their treatment progress. PMID- 29172055 TI - Offspring of depressed and anxious patients: Help-seeking after first onset of a mood and/or anxiety disorder. AB - BACKGROUND: Offspring of patients with depressive and/or anxiety disorders are at high risk of developing a similar disorder themselves. Early recognition and treatment may have substantial effects on prognosis. The main aim of this study was to examine the time to initial help-seeking and its determinants in offspring after the first onset of a mood and/or anxiety disorder. METHODS: Data are presented of 215 offspring with a mood and/or anxiety disorder participating in a cohort study with 10 year follow-up. We determined age of disorder onset and age of initial help-seeking. Offspring characteristics (gender, IQ, age of onset, disorder type, suicidal ideation) and family characteristics (socioeconomic status, family functioning) were investigated as potential predictors of the time to initial help-seeking. RESULTS: The estimated overall proportion of offspring of depressed/anxious patients who eventually seek help after onset of a mood and/or anxiety disorder was 91.9%. The time to initial help-seeking was more than two years in 39.6% of the offspring. Being female, having a mood disorder or comorbid mood and anxiety disorder (relative to anxiety) and a disorder onset in adolescence or adulthood (relative to childhood) predicted a shorter time to initial help-seeking. LIMITATIONS: Baseline information relied on retrospective reports. Age of onsets and age of initial help-seeking may therefore be subject to recall bias. CONCLUSION: Although most offspring eventually seek help after onset of a mood/anxiety disorder, delays in help-seeking were common, especially in specific subgroups of patients. This information may help to develop targeted strategies to reduce help-seeking delays. PMID- 29172056 TI - Electroconvulsive therapy and age: Age-related clinical features and effectiveness in treatment resistant major depressive episode. AB - OBJECTIVE: This study was aimed to compare clinical features, treatments outcomes and tolerability between young (18-45 years), middle age (46-64 years) and old (>= 65 years) patients treated with bilateral ECT for treatment resistant major depressive episode. METHOD: 402 patients were evaluated 1 day prior to ECT and a week after the treatment termination using the Clinical Global Impression Scale (CGI), the Hamilton Rating Scale for Depression-17 items (HAM-D-17), the Brief Psychiatric Rating Scale (BPRS), the Young Mania Rating Scale (YMRS) and the Mini Mental State Examination (MMSE). Response was defined as a reduction of at least 50% from baseline on the HAM-D-17 score. Remission was defined as a score <= 7 on the HAM-D-17 at the final evaluation. RESULTS: Rates of response were not statistically different in the three groups (69.6% in old versus 63.5% in young and 55.5% in middle age groups). No significant differences were also observed in the proportions of remitters between the age groups (31.4% in young group, 27.7% in middle age group and 29.3% in old group). One week after the end of the ECT course the middle and old age groups showed a statistically significant increase in the MMSE score compared to baseline. We did not find significant differences between the three age groups in rates of premature drops-out due to ECT-related side effects. CONCLUSION: Our data support the use of ECT in elderly patients with treatment-resistant major depressive episode, with rates of response around 70% and effectiveness being independent from age. In the old age group the baseline cognitive impairment improved after ECT and no life-threatening adverse event was detected.

AB - The purpose of this articl is to explore nursing students' experiences of dialogic group oral exams used in the assessment of a medical nursing course. We discuss a small-group, educator-facilitated exam (dialogue exam). The data were gathered in April 2015 via an online survey including open questions. The participants were nursing students (n = 58) at a University of Applied Sciences. The data were subjected to inductive content analysis. The results suggest that students' experiences of the dialogue exam can be represented by four themes: context bound dynamics, new shared understanding, verified competences and holistic nursing care. The students liked the dialogue exam format, preferring it to the traditional individual written exam. The prerequisite for successful use of the dialogue exam format is that candidates perceived the exam situation as safe. Students need to be given information about the schedule and assessment criteria beforehand and should have some experience of the format.

AB - Cerebral damage secondary to the vasospasm due to subarachnoid hemorrhage (SAH) is an important cause of morbid-mortality. We propose the use of the PET tracer [18F]Fluoromisonidazole to visualize the hypoxia due to the vasospasm. On the other hand [18F]Fluoromisonidazole synthesis process was optimized, avoiding HPLC purification using SPE cartridges instead, and reducing some synthesis steps. [18F]Fluoromisonidazole in vitro stability was tested for ten hours, and in vivo PET/CT images showed higher cerebral uptake in hemorrhagic animals than in control rats. PMID- 29172059 TI - Hydroxamate column-based purification of zirconium-89 (89Zr) using an automated fluidic platform. AB - Zirconium-89 (89Zr) is a long-lived (t1/2 = 78.4h) positron-emitting isotope that is useful for positron emission tomography (PET) based diagnostic imaging using radiolabeled antibodies. Hydroxamate resin columns are predominantly used for the purification of 89Zr from cyclotron bombarded natY targets dissolved in strong HCl. 89Zr is conventionally eluted from the resin in 1M oxalic acid (H2C2O4), a complexant that is conducive to follow-on binding of 89Zr through a transchelation process to the deferoxamine siderophore. In the present study, we determined that a lower concentration of H2C2O4 eluent (0.8M) is adequate to efficiently remove 89Zr from a column containing 100mg hydroxamate resin. As a result, less buffering agents are needed to be added to the 89Zr product fraction prior to labeling. A simple automated fluidic system prototype has been developed to perform the steps required for 89Zr purification using a hydroxamate resin column (column conditioning in HCl, Y target dissolution, dissolved target solution load onto column, column washes using HCl and water, and 89Zr elution). The system performance was evaluated using several cyclotron bombarded Y targets; 89Zr product fractions demonstrated excellent chemical recoveries from these targets, with 1.0mL product volumes yielding 89+/-2% of the column elution peak activity and 84+/-2% of 89Zr recovered from the target (at EOB). These results compare favorably with previously published 89Zr product volumes and yields, despite the lower concentration of H2C2O4 eluent employed. Transchelation of resulting 89Zr product fractions was performed to assess product quality. The effective specific activity (ESA) ranged between 44(7) and 109(22) TBq.mmole-1, while the bindable metals concentration, a metric introduced for assessing and comparing product purity, ranged between 43(7) and 115(27) nmole.g-1. PMID- 29172060 TI - Thinness pressures in ethnically diverse college women in the United States. AB - While research consistently supports the negative impact of thinness pressures on body image, this work has primarily utilized White samples in the United States, limiting generalizability to other ethnicities. Further, limited research has examined ethnic differences in thinness pressures from distinct sociocultural influences. This study examined distinct sources of thinness pressures in 598 White, 135 Black, and 131 Hispanic college women in the United States. Mean levels of thinness pressures significantly differed across ethnicity, with Black women generally reporting the lowest levels of each pressure. Additionally, distinct sources of thinness pressures were more highly related to negative outcomes within ethnic groups. For White women, each source was salient for disordered eating. For Black women, family pressure was particularly salient for appearance evaluation. For Hispanic women, family pressure was particularly salient for disordered eating and appearance evaluation. Findings suggest possible ethnic differences in the relative salience of some pressures over others. PMID- 29172061 TI - Self-objectification, body shame, and disordered eating: Testing a core mediational model of objectification theory among White, Black, and Hispanic women. AB - Objectification theory asserts that self-objectification, which manifests as self surveillance, leads to increased body shame and subsequent eating pathology. Although evidence supports the core mediational model, the majority of this work utilizes primarily White samples, limiting generalizability to other ethnic groups. The current study examined whether the core tenets of objectification theory generalize to Black and Hispanic women. Participants were 880 college women from the United States (71.7% White, 15.1% Hispanic, 13.2% Black) who completed self-report measures of self-surveillance, body shame, and disordered eating. Multivariate analysis of variance tests indicated lower levels of self surveillance and disordered eating among Black women. Moreover, body shame mediated the relationship between self-surveillance and disordered eating for White and Hispanic women, but not for Black women. These analyses support growing evidence for the role of body shame as a mediator between body surveillance and eating pathology, but only for women in certain ethnic groups. PMID- 29172062 TI - Association of nutrition and immune-endocrine dysfunction with muscle mass and performance in cognitively impaired older adults. AB - BACKGROUND: With lean mass declining early in Alzheimer's disease, muscle quality beyond quantity is relevant to physical performance. We sought to identify potentially modifiable factors for the differential loss of muscle mass (pre sarcopenia) and its performance (sarcopenia) in older adults with mild cognitive impairment (MCI) and mild-to-moderate Alzheimer's disease (AD). METHODS: This is a cross-sectional study of 108 community-dwelling older adults with MCI and mild to-moderate AD. Participants were categorized as: (i) No sarcopenia (normal muscle mass), (ii) Pre-sarcopenia (low muscle mass without weakness or slowness), (iii) Sarcopenia (low muscle mass AND weak grip strength and/or slow gait speed) using Asian cut-offs. Muscle quality was defined as the ratio of grip and knee extension strength to average arm and leg lean mass respectively. We measured cognitive, functional and physical (Short Physical Performance Battery, SPPB) performance; physical activity level; nutritional status; and blood biomarkers of inflammation and endocrine dysfunction. RESULTS: SPPB (p=0.033) and activity level (p=0.010) were highest in the pre-sarcopenic group. Pre-sarcopenic group had highest arm muscle quality [10.6 (7.7-12.2) vs 13.9 (12.6-15.7) vs 11.3 (9.7 12.8), p<0.001], despite significantly lower appendicular lean mass than non sarcopenic group. In multi-nomial logistic regression reference to non-sarcopenic group, malnutrition independently increased risk for both pre-sarcopenia (Relative risk=7.53, 95% C.I 1.20-47.51, p=0.032) and sarcopenia (Relative risk=11.91, 95% C.I 2.85-49.77, p=0.001). A combined pro-inflammatory and endocrine deficient state significantly increased the risk of sarcopenia (Relative risk=5.17, 95% C.I 1.31-20.37, p=0.019). CONCLUSION: Malnutrition is a precursor for progressive loss of muscle mass, but a pro-inflammatory and endocrine deficient state may potentially aggravate decline in muscle quality to culminate in frank sarcopenia. PMID- 29172063 TI - Protective effect of catechin on humoral and cell mediated immunity in rat model. AB - The present study was focused on examining the effect of catechin on the cellular and humoral immunity in rat model. Immunomodulatory effect of catechin was determined by delayed-type hypersensitivity (DTH) response, carbon clearance assay, leucocyte mobilization test and cyclophosphamide-induced myelosuppression and hemagglutinating antibody (HA) titer assay. Catechin in experimental dose (25, 50 and 100mg/kg, p.o.) elevated a significant increase in antibody titer in the hemagglutination test with increased levels of immunoglobulin. There was an enhancement in the delayed-type hypersensitivity reaction produced by sheep red blood cells. There was also restoration in the functioning of leucocytes in cyclophosphamide-treated rats with an increased clearance of carbon particles. The results of the present study signify that catechin possesses sufficient potential for modulating immune activity by cellular and humoral mechanisms. PMID- 29172064 TI - Propofol attenuates myocardial ischemia reperfusion injury partly through inhibition of resident cardiac mast cell activation. AB - Cardiac mast cell activation is involved in the process of myocardial ischemia reperfusion (I/R) injury and exacerbates myocardial infarction. Propofol, an anesthetic with antioxidant property, can reduce myocardial infarct size in I/R injury. The present study was designed to investigate whether propofol can attenuate myocardial I/R injury by inhibiting resident cardiac mast cell activation by a Langendorff model. Thirty rats were randomly assigned to 5 groups (n=6 per group): control group and four test groups (I/R, I/R+compound 48/80, I/R+propofol, I/R+compound 48/80+propofol). Cultured RBL-2H3 cells were pretreated with propofol and subjected to mast cell degranulator compound48/80 (C48/80).Microscopically, degradation of myofibrillar and degranulation of mast cells were studied using hematoxylin-eosin toluidine blue staining techniques. After the effluent was assayed for tryptase, LDH, CK-MB and cTnI, myocardial tissue was evaluated for cytokine levels and infarct area. Heart subjected to I/R showed significantly increased expression of cytokines (TNF-alpha and IL-6), LDH, CK-MB and cTnI. In addition, the I/R-induced heart also showed greater histopathological injury and a larger infarction zone, following increased mast cell degranulation with concomitant rise in tryptase. Mast cell degranulation by C48/80 further aggravated I/R injury. However, all of these effects were suppressed by propofol pretreatment, which also abrogated C48/80-mediated exacerbation of I/R injury. Also, propofol attenuated the C48/80-evoked tryptase and histamine release in RBL-2H3 cells. It is concluded that pretreatment of propofol confers protection against I/R injury partly by inhibiting resident cardiac mast cell activation. PMID- 29172065 TI - DNA methylation markers in combination with skeletal and dental ages to improve age estimation in children. AB - Age estimation is critical in forensic science, in competitive sports and games and in other age-related fields, but the current methods are suboptimal. The combination of age-associated DNA methylation markers with skeletal age (SA) and dental age (DA) may improve the accuracy and precision of age estimation, but no study has examined this topic. In the current study, we measured SA (GP, TW3-RUS, and TW3-Carpal methods) and DA (Demirjian and Willems methods) by X-ray examination in 124 Chinese children (78 boys and 46 girls) aged 6-15 years. To identify age-associated CpG sites, we analyzed methylome-wide DNA methylation profiling by using the Illumina HumanMethylation450 BeadChip system in 48 randomly selected children. Five CpG sites were identified as associated with chronologic age (CA), with an absolute value of Pearson's correlation coefficient (r)>0.5 (p<0.01) and a false discovery rate<0.01. The validation of age associated CpG sites was performed using droplet digital PCR techniques in all 124 children. After validation, four CpG sites for boys and five CpG sites for girls were further adopted to build the age estimation model with SA and DA using multivariate linear stepwise regressions. These CpG sites were located at 4 known genes: DDO, PRPH2, DHX8, and ITGA2B and at one unknown gene with the Illumina ID number of 22398226. The accuracy of age estimation methods was compared according to the mean absolute error (MAE) and root mean square error (RMSE). The best single measure for SA was the TW3-RUS method (MAE=0.69years, RMSE=0.95years) in boys, and the GP method (MAE=0.74years, RMSE=0.94years) in girls. For DA, the Willems method was the best single measure for both boys (MAE=0.63years, RMSE=0.78years) and girls (MAE=0.54years, RMSE=0.68years). The models that incorporated SA and DA with the methylation levels of age-associated CpG sites provided the highest accuracy of age estimation in both boys (MAE=0.47years, R2=0.886) and girls (MAE=0.33years, R2=0.941). Cross validation of the results confirmed the reliability and validity of the models. In conclusion, age associated DNA methylation markers in combination with SA and DA greatly improve the accuracy of age estimation in Chinese children. This method may be applied in forensic science, in competitive sports and games and in other age-related fields. PMID- 29172066 TI - Discrimination of relationships with the same degree of kinship using chromosomal sharing patterns estimated from high-density SNPs. AB - Distinguishing relationships with the same degree of kinship (e.g., uncle-nephew and grandfather-grandson) is generally difficult in forensic genetics by using the commonly employed short tandem repeat loci. In this study, we developed a new method for discerning such relationships between two individuals by examining the number of chromosomal shared segments estimated from high-density single nucleotide polymorphisms (SNPs). We computationally generated second-degree kinships (i.e., uncle-nephew and grandfather-grandson) and third-degree kinships (i.e., first cousins and great-grandfather-great-grandson) for 174,254 autosomal SNPs considering the effect of linkage disequilibrium and recombination for each SNP. We investigated shared chromosomal segments between two individuals that were estimated based on identity by state regions. We then counted the number of segments in each pair. Based on our results, the number of shared chromosomal segments in collateral relationships was larger than that in lineal relationships with both the second-degree and third-degree kinships. This was probably caused by differences involving chromosomal transitions and recombination between relationships. As we probabilistically evaluated the relationships between simulated pairs based on the number of shared segments using logistic regression, we could determine accurate relationships in >90% of second-degree relatives and >70% of third-degree relatives, using a probability criterion for the relationship >=0.9. Furthermore, we could judge the true relationships of actual sample pairs from volunteers, as well as simulated data. Therefore, this method can be useful for discerning relationships between two individuals with the same degree of kinship. PMID- 29172067 TI - Improving communication at handover and transfer reduces retained swabs in maternity services. AB - OBJECTIVE: To reduce the incidence of retained vaginal swabs and near misses. STUDY DESIGN: A review of previous retained swab incidents and near misses in a large maternity unit identified handovers and transfers as a key point of vulnerability. Interventions were introduced to improve communication at handover from the delivery suite to theatre and from theatre to the high dependency unit. Process data was collected to monitor compliance. The outcome measures were the incidence of retained swab never events and the incidence of near misses. Chi squared analysis was used to test the significance of the results. RESULTS: For transfers from delivery suite to theatre, verbal handover significantly increased from 28.8% to 75.6% (p<0.0001), and written handover significantly increased from 4.4% to 62.9% (p<0.0001). There were 291 transfers to theatre post-intervention: in 88 (30.2%) of these transfers a vaginal swab was already in situ. In 70/88 (79.5%) of cases the presence of the swab was communicated to theatre staff in three ways (verbally, written and transfer of opened swab packets) according to the new policy. In the post-intervention period there were 56 women transferred from theatre to the high-dependency unit with a vaginal pack in situ: 52 (92.9%) of these women had a sticker in place serving as a constant reminder of the presence of the vaginal pack to staff. Following a baseline of four near misses in two months, there has been only one near miss in the 15 months since the interventions were implemented, (33.3% vs. 1.1%, p<0.0001). There have been no retained swab incidents since the project commenced. CONCLUSIONS: Simple interventions to improve communication at handover and transfer can reduce the incidence of retained vaginal swabs and near misses. Further work is needed to raise the profile of swab counting in maternity settings: swab counting needs to be the responsibility of all disciplines, not just the responsibility of theatre staff. PMID- 29172068 TI - Gestational diabetes-Predictors of response to treatment and obstetric outcome. AB - OBJECTIVE: Evaluate patient characteristics that are predictors of treatment response and outcomes in gestational diabetes STUDY DESIGN: Retrospective cohort of 265 women with gestational diabetes treated with diet/metformin and/or insulin in a single centre over 2 years. RESULTS: Multinomial logistic regression showed that (after adjusting for age and ethnicity) women who were of normal weight were more likely to be on diet and women who were obese were more likely to be on metformin or metformin and insulin(p=0.014). Women who were obese were twice more likely to have labour induced than those with normal weight. Onset of labour was the only parameter significantly associated with a treatment modality among the three groups (p<0.001). There was no difference in the incidence of large for gestational age, neonatal admission, shoulder dystocia or still birth between the three groups. CONCLUSIONS: Maternal BMI appears to be the only parameter that is predictive of need for treatment with metformin/insulin and the modality of treatment does not have an effect on maternal and neonatal outcomes. PMID- 29172069 TI - Antimutagenic action of the live yeast can be transmitted to the offspring of Drosophila melanogaster. A genetic study using the wing spot assay. AB - The present study evaluates whether the protective effect of live yeast (LY) against direct and indirect mutagenic agents, persists in the offspring from individuals fed with LY. The wing-spot test in Drosophila was used; four different mates were performed: a) neither females nor males were fed with LY enriched food (NLYxNLY); b) only females were fed (LYxNLY); c) males were fed (NLYxLY) or d) both progenitors were fed (LYxLY). Results confirm that LY strongly stimulates fecundity in females but not in males and provides strength to the egg for survive. A greater reduction in mutation rate was observed when females were feed, in the following relationship: LYxNLY>LYxLY>NLYxLY. No protection was found against action in any of the promutagens tested. Results suggest that LY has a very powerful antimutagenic action, predominantly against the action of ionizing radiation and Chromium trioxide that can be transmitted mainly through the female. PMID- 29172070 TI - Vertical transmission of positive-sense single-stranded RNA viruses in plants as a model for arboviral induced teratogenesis. AB - Teratogenic viruses have increased public health importance with the emergence of Zika virus and a recent decline in rubella virus vaccination. Of the seven viruses known to cause birth defects in humans, three are mosquito-borne pathogens. Ethical oversight, compliance, rising costs, and the need for specialized training slow the pace of study of these human pathogens compared to study of similar teratogenic viruses in plants. Plant viruses have served as models for human viruses which can be applied to animal systems. This review describes the similar features of plant and animal teratogenic arboviruses and the common systems and barriers that are encountered during vertical transmission in the host. PMID- 29172072 TI - Reproductive effects of arteriviruses: equine arteritis virus and porcine reproductive and respiratory syndrome virus infections. AB - Equine arteritis virus (EAV) and porcine reproductive and respiratory syndrome virus (PRRSV) are the most economically important members of the family Arteriviridae. EAV and PRRSV cause reproductive and respiratory disease in equids and swine, respectively and constitute a significant economic burden to equine and swine industries around the world. Furthermore, they both cause abortion in pregnant animals and establish persistent infection in their natural hosts, which fosters viral shedding in semen leading to sexual transmission. The primary focus of this article is to provide an update on the effects of these two viruses on the reproductive tract of their natural hosts and provide a comparative analysis of clinical signs, virus-host interactions, mechanisms of viral pathogenesis and viral persistence. PMID- 29172071 TI - Zika virus infection of first-trimester human placentas: utility of an explant model of replication to evaluate correlates of immune protection ex vivo. AB - The emergence of congenital Zika virus (ZIKV) disease, with its devastating effects on the fetus, has prompted development of vaccines and examination of how ZIKV breaches the maternal-fetal barrier. Infection of placental and decidual tissue explants has demonstrated cell types at the uterine-placental interface susceptible to infection and suggests routes for transmission across the placenta and amniochorionic membrane. ZIKV replicates in proliferating Hofbauer cells within chorionic villi in placentas from severe congenital infection. Explants of anchoring villi recapitulate placental architecture and early-stage development and suggest infected Hofbauer cells disseminate virus to fetal blood vessels. ZIKV infection of explants represents a surrogate human model for evaluating protection against transmission by antibodies in vaccine recipients and passive immune formulations and novel therapeutics. PMID- 29172073 TI - Intrinsic sodium currents and excitatory synaptic transmission influence spontaneous firing in up and down activities. AB - Periodic up and down transitions of membrane potentials are considered to be a significant spontaneous activity. These kinds of oscillations always accompany with some spontaneous firing in up state. Our previous theoretical studies mainly looked at the subthreshold up and down transitions and characteristics of up and down dynamics. In this paper, we focus on suprathreshold spontaneous firing of up and down transitions based on improved network model and its stimulations. The simulated results indicate that fast sodium current is critical to the generation of spontaneous neural firing. While persistent sodium current plays a part in spontaneous fluctuation. Both intrinsic fast and persistent sodium dynamics influence spontaneous firing rate and synchronous activity in up and down behavior. Meanwhile, blocking excitatory synaptic transmission decreases neural firing and reveals spontaneous firing. These simulated results are basically in accordance with experimental results. Through the observation and analysis of the findings, we prove the validity of the model so we can further adopt this model to study other properties and characteristics of the network, laying the foundation for further work on cortex activity. PMID- 29172074 TI - Using rotated speech to approximate the acoustic mismatch negativity response to speech. AB - The mismatch negativity (MMN) response is influenced by the magnitude of the acoustic difference between standard and deviant, and the response is typically larger to linguistically relevant changes than to linguistically irrelevant changes. Linguistically relevant changes between standard and deviant typically co-occur with differences between the two acoustic signals. It is therefore not straightforward to determine the contribution of each of those two factors to the MMN response. This study investigated whether spectrally rotated speech can be used to determine the impact of the acoustic difference on the MMN response to a combined linguistic and acoustic change between standard and deviant. Changes between rotated vowels elicited an MMN of comparable amplitude to the one elicited by a within-category vowel change, whereas the between-category vowel change resulted in an MMN amplitude of greater magnitude. A change between rotated vowels resulted in an MMN ampltude more similar to that of a within-vowel change than a complex tone change did. This suggests that the MMN amplitude reflecting the acoustic difference between two speech sounds can be well approximated by the MMN amplitude elicited in response to their rotated counterparts, in turn making it possible to estimate the part of the response specific to the linguistic difference. PMID- 29172075 TI - Real-time RT-PCR for Mayaro virus detection in plasma and urine. AB - BACKGROUND: Mayaro virus (MAYV) causes an acute febrile illness which can be difficult to differentiate from dengue or chikungunya. MAYV RNA can be detected in plasma during the first 3-5days of illness, but only a single rRT-PCR has been fully evaluated in the literature. OBJECTIVES: To develop an rRT-PCR for MAYV and evaluate assay performance using human plasma and urine samples spiked with different MAYV strains. STUDY DESIGN: A MAYV rRT-PCR targeting a region of the 5'UTR and nsp1 gene was designed from the alignment of all complete-genome MAYV sequences to be compatible with existing laboratory protocols. The assay was evaluated using human samples spiked with six MAYV strains, including strains from each of the three genotypes. RESULTS: The linear range of the MAYV rRT-PCR extended from 1.0 to 8.0 log10copies/MUL, and the lower limit of 95% detection was 8.2copies/MUL. No detection was observed when the MAYV rRT-PCR was tested with genomic RNA from related arboviruses. The assay demonstrated linear amplification of all 6 MAYV strains when spiked into human plasma samples as well as 2 strains spiked into urine. CONCLUSIONS: We report the design and evaluation of an rRT-PCR for MAYV. Given the concern for MAYV emergence in the Americas and the few molecular tests that have been evaluated in the literature, this assay should provide a useful diagnostic for patients with an acute febrile illness. PMID- 29172076 TI - Gemtuzumab Ozogamicin (GO) Inclusion to Induction Chemotherapy Eliminates Leukemic Initiating Cells and Significantly Improves Survival in Mouse Models of Acute Myeloid Leukemia. AB - Gemtuzumab ozogamicin (GO) is an anti-CD33 antibody-drug conjugate for the treatment of acute myeloid leukemia (AML). Although GO shows a narrow therapeutic window in early clinical studies, recent reports detailing a modified dosing regimen of GO can be safely combined with induction chemotherapy, and the combination provides significant survival benefits in AML patients. Here we tested whether the survival benefits seen with the combination arise from the enhanced reduction of chemoresidual disease and leukemic initiating cells (LICs). Herein, we use cell line and patient-derived xenograft (PDX) AML models to evaluate the combination of GO with daunorubicin and cytarabine (DA) induction chemotherapy on AML blast growth and animal survival. DA chemotherapy and GO as separate treatments reduced AML burden but left significant chemoresidual disease in multiple AML models. The combination of GO and DA chemotherapy eliminated nearly all AML burden and extended overall survival. In two small subsets of AML models, chemoresidual disease following DA chemotherapy displayed hallmark markers of leukemic LICs (CLL1 and CD34). In vivo, the two chemoresistant subpopulations (CLL1+/CD117- and CD34+/CD38+) showed higher ability to self renewal than their counterpart subpopulations, respectively. CD33 was coexpressed in these functional LIC subpopulations. We demonstrate that the GO and DA induction chemotherapy combination more effectively eliminates LICs in AML PDX models than either single agent alone. These data suggest that the survival benefit seen by the combination of GO and induction chemotherapy, nonclinically and clinically, may be attributed to the enhanced reduction of LICs. PMID- 29172077 TI - Photoresponsive azo-combretastatin A-4 analogues. AB - Colchicine analogues in which an azo group is incorporated into a molecule containing the key pharmacophore of colchicine, have found particular utility as switchable tubulin binding chemotherapeutics. Combretastatin is a related compound containing a stilbene fragment that shows different bioactivity for the cis and trans isomers. We have performed cell assays on 17 new compounds structurally related to a previously reported azo-analogue of combretastatin. One of these compounds showed enhanced potency against HeLa (IC50 = 0.11 MUM) and H157 cells (IC50 = 0.20 MUM) for cell studies under 400 nm irradiation and the highest photoactivity (IC50 with irradiation/IC50 in dark = 550). We have performed docking and physicochemical studies of this new compound (7). Kinetic studies in water reveal a longer half-life for the cis isomer of 7 which may be one factor responsible for the better IC50 values in cell assays and the improved photoresponsive behavior.

PMID- 29172079 TI - Design, syntheses and lipid accumulation inhibitory activities of novel resveratrol mimics. AB - Hispidine was initially discovered from Ficus Hispida for cardiovascular protection. In this paper, hispidine derivatives, which contain a novel resveratrol-like scaffold, have been designed, synthesized, and assayed as agents against lipid accumulations in 3T3-L1 pre-adipocytes. Six hispidine derivatives have the activity of reducing TG in 3T3-L1 adipocytes in dosage-dependent manner. The most active compound can reduce the lipid accumulation up to 78.4% at 10 MUM qPCR and Western blotting results demonstrate that the two most active compounds inhibit both lipodenesis and adipogenesis in 3T3-L1 cells through (1) increasing the phosphorylations of AMPK and ACC, promoting SIRT1 expression. These three proteins are key regulators for lipogenesis and energy metabolism. (2) Decreasing the expressions of PPARgamma, sREBP-1c, and FABP4, which are pivotal regulators for adipogenesis. Overall, this work proves that hispidine derivatives diminish the lipid accumulation in 3T3-L1 cell line by downregulating lipogenic and adipogenic pathways.

Such unprecedented pharmacophores were accessed using an aminomethylalcohol derivative at C-17 as the key intermediate; reaction of such functionality with triphosgene, or conversion into N-substituted thioureas, followed by an intramolecular cyclodesulfurization reaction promoted by yellow HgO, furnished such spirocycles in excellent yields. Title compounds were tested in vitro against a panel of six human tumor cell lines, named A549 (non-small cell lung), HBL-100 (breast), HeLa (cervix), SW1573 (non-small cell lung), T-47D (breast) and WiDr (colon), and the results were compared with steroidal chemotherapeutic agents (abiraterone and galeterone); the A-ring of the steroidal backbone, the nature of the heterocycle and the N-substituents proved to be essential motifs for establishing structure-activity relationships concerning not only the potency but also the selectivity against tumor cell lines. Estrone derivatives, particularly those bearing a spiranic 2-aminooxazoline scaffold were found to be the most active compounds, with GI50 values ranging from the low micromolar to the submicromolar level (0.34-1.5 MUM). Noteworthy, the lead compounds showed a remarkable increase in activity against the resistant cancer cell lines (T-47D and WiDr) compared to the anticancer reference drugs (up to 120 fold). PMID- 29172081 TI - Discovery of novel propargylamine-modified 4-aminoalkyl imidazole substituted pyrimidinylthiourea derivatives as multifunctional agents for the treatment of Alzheimer's disease. AB - A series of novel propargylamine-modified pyrimidinylthiourea derivatives (1-3) were designed and synthesized as multifunctional agents for Alzheimer's disease (AD) therapy, and their potential was evaluated through various biological experiments. Among these derivatives, compound 1b displayed good selective inhibitory activity against AChE (vs BuChE, IC50 = 0.324 MUM, SI > 123) and MAO-B (vs MAO-A, IC50 = 1.427 MUM, SI > 35). Molecular docking study showed that the pyrimidinylthiourea moiety of 1b could bind to the catalytic active site (CAS) of AChE, and the propargylamine moiety interacted directly with the flavin adenine dinucleotide (FAD) of MAO-B. Moreover, 1b demonstrated mild antioxidant ability, good copper chelating property, effective inhibitory activity against Cu2+ induced Abeta1-42 aggregation, moderate neuroprotection, low cytotoxicity, and appropriate blood-brain barrier (BBB) permeability in vitro and was capable of ameliorating scopolamine-induced cognitive impairment in mice. These results indicated that 1b has the potential to be a multifunctional candidate for the treatment of Alzheimer's disease. PMID- 29172082 TI - Discovery and structure-activity relationship of novel 4-hydroxy-thiazolidine-2 thione derivatives as tumor cell specific pyruvate kinase M2 activators. AB - Pyruvate kinase M2 isoform (PKM2) is a crucial protein responsible for aerobic glycolysis of cancer cells. Activation of PKM2 may alter aberrant metabolism in cancer cells. In this study, we discovered a 4-hydroxy-thiazolidine-2-thione compound 2 as a novel PKM2 activator from a random screening of an in-house compound library. Then a series of novel 4-hydroxy-thiazolidine-2-thione derivatives were designed and synthesized for screening as potent PKM2 activators. Among these, some compounds showed higher PKM2 activation activity than lead compound 2 and also exhibited significant anti-proliferative activities on human cancer cell lines at nanomolar concentration. The compound 5w was identified as the most potent antitumor agent, which showed excellent anti proliferative effects with IC50 values from 0.46 MUM to 0.81 MUM against H1299, HCT116, Hela and PC3 cell lines. 5w also showed less cytotoxicity in non-tumor cell line HELF compared with cancer cells. In addition, Preliminary pharmacological studies revealed that 5w arrests the cell cycle at the G2/M phase in HCT116 cell line. The best PKM2 activation by compound 5t was rationalized through docking studies. PMID- 29172083 TI - Novel aminopyrimidinyl benzimidazoles as potentially antimicrobial agents: Design, synthesis and biological evaluation. AB - A series of novel aminopyrimidinyl benzimidazoles as potentially antimicrobial agents were designed, synthesized and characterized by IR, NMR and HRMS spectra. The biological evaluation in vitro revealed that some of the target compounds exerted good antibacterial and antifungal activity in comparison with the reference drugs. Noticeably, compound 7d could effectively inhibit the growth of A. flavus, E. coli DH52 and MRSA with MIC values of 1, 1 and 8 MUg/mL, respectively. Further studies revealed that pyrimidine derivative 7d could exhibit bactericidal mode of action against both Gram positive (S. aureus and MRSA) and Gram negative (P. aeruginosa) bacteria. The active molecule 7d showed low cell toxicity and did not obviously trigger the development of resistance in bacteria even after 16 passages. Furthermore, compound 7d was able to beneficially regulate reactive oxygen species (ROS) generation for an excellent safety profile. Molecular docking study revealed that compound 7d could bind with DNA gyrase by the formation of hydrogen bonds. The preliminary exploration for antimicrobial mechanism disclosed that compound 7d could effectively intercalate into calf thymus DNA to form a steady supramolecular complex, which might further block DNA replication to exert the powerful bioactivities. The binding investigation of compound 7d with human serum albumins (HSA) revealed that this molecule could be effectively transported by HSA. PMID- 29172084 TI - Synthesis and biological evaluation of N-substituted 3-oxo-1,2,3,4-tetrahydro quinoxaline-6-carboxylic acid derivatives as tubulin polymerization inhibitors. AB - A series of novel N-substituted 3-oxo-1,2,3,4-tetrahydro-quinoxaline-6-carboxy- lic acid derivatives were synthesized and evaluated for their biological activities. Among all synthesized target compounds, 13d exhibited the most potent antiproliferative activity against HeLa, SMMC-7721, K562 cell line (IC50 = 0.126 MUM, 0.071 MUM, 0.164 MUM, respectively). Furthermore, compound 13d inhibited tubulin polymerization (IC50 = 3.97 MUM), arrested cell cycle at the G2/M phase and induced apoptosis. The binding mode at the colchicine binding site was also probed. These studies provided a new molecular scaffold for the further development of antitumor agents that target tubulin. PMID- 29172085 TI - Design, synthesis and pharmacological evaluation of N-(5-chloro-2,4 dihydroxybenzoyl)-(R)-N-arylmethyl-1,2,3,4-tetrahydro-3-isoquinolinecarboxamides as potent Hsp90 inhibitors. AB - Using diverse arylmethyl groups to replace the benzyl moiety of the lead Hsp90 inhibitor 1 (N-(5-chloro-2,4-dihydroxybenzoyl)-(R)-N-benzyl-1,2,3,4-tetrahydro-3 iso quinolinecarboxamide), thirty four derivatives (10-43) were developed, and exhibited improved Hsp90 inhibitory and antiproliferative activities. SAR analysis indicated that the southeastern aryl substitutions influenced their antiproliferative activities obviously, with the para-pyridyl group (41) outperforming all other substitution patterns. In this regard, compound 41 was selected for further evaluation. CETSA melt and ITDRFCETSA (isothermal dose response fingerprint) curves for Hsp90alpha further proved that 41 interacted with intracellular Hsp90alpha powerfully. Compared with the lead compound 1, docking and MD refinement of the Hsp90alpha-41 complex revealed a favorable H bonding interaction between the side-chain of Tyr139 and the pyridine moiety of 41, which is the first time to be used for resorcinol-based Hsp90 inhibitors. With broad-spectral antitumor activity, compound 41 induced time- and dose dependent growth inhibition and G0/G1 cell cycle arrest on human breast cancer MDA-MB-453 cell line. In addition, flow cytometry and Western blot analyses confirmed that 41 induced apoptosis of human breast cancer MDA-MB-453 cell line. Via degradation of IKKs and suppression of IKKs activity, compound 41 inhibited TNF-alpha-induced NF-kappaB activation. The overall properties warrant compound 41 a promising Hsp90 inhibitor and further biological characterizations. This study provides insights into the chemical evolution of Hsp90 inhibitors, and may facilitate the design of next generation Hsp90 inhibitors for the antitumor drug development. PMID- 29172087 TI - Development of a group work assessment pedagogy using constructive alignment theory. AB - The purpose of this paper is to explore group work assessment underpinned by constructive alignment theory to develop a new assessment pedagogy. A review was undertaken of an existing module 'Mental Health Nursing 1', with student nurses participating in the BSc (Hons) Nursing Programme. Constructive alignment theory requires teachers to adopt a deep approach to learning where module learning outcomes are aligned with the teaching environment and modes of assessment. As the module progressed, reviewing the Mental Health Nursing 1 module became an excellent opportunity to begin to understand how constructive alignment theory can inform a group work assessment pedagogy. Working using a constructively aligned assessment process became a valuable learning experience for the module leader whilst at the same time revealed a gap in the research around the impact of constructively aligned teaching and group work assessment. PMID- 29172086 TI - Synthesis of new 1-benzyl tetrahydropyridinylidene ammonium salts and their antimicrobial and anticellular activities. AB - A series of N-benzyl tetrahydropiperidinylidene pyrrolidinium salts have been synthesized and investigated for their antiplasmodial and antitrypanosomal activities as well as for their cytotoxic effects. The antibacterial, antimycobacterial and anticancer potencies of selected compounds were examined, too. Physicochemical parameters were calculated and structure-activity relationships are discussed. PMID- 29172088 TI - Silencing of H19 inhibits the adipogenesis and inflammation response in ox-LDL treated Raw264.7 cells by up-regulating miR-130b. AB - Atherosclerosis (AS) is the main cause of cardiovascular diseases (CADs). Lipid accumulation and inflammatory response in macrophages are two key factors in the pathogenesis of AS. In this study, we aimed to explore the regulating role of long non-coding RNA (LncRNA)-H19 in oxygenized low density lipoprotein (ox-LDL) treated Raw264.7 cells. Compared with the healthy control, a relatively higher level of H19 was detected in the blood samples from AS patients. Obviously up regulated expression of TG (triglycerides)/TC (total cholesterol)/LDL-C (low density lipoprotein-cholesterol) and down-regulated level of HDL-C (high density lipoprotein-cholesterol) were detected in ox-LDL-treated Raw264.7 cells. Besides that, increased expression of H19 was detected in ox-LDL-treated Raw264.7 cells. To examine the function of H19, gene knockdown was performed using short hairpin RNAs (shRNAs). The expression of TG, TC, LDL-C and HDL-C was detected by enzyme linked immunosorbent assay (Elisa) and the expression of lipolytic genes/lipogenic genes (PPARalpha, CPT-1/REBP-1c, ACS) was examined through western blot. In combination with the result of oil red O staining, we concluded that H19 shRNA effectively decreased lipid accumulation in ox-LDL-treated Raw264.7 cells. Besides that, H19 shRNA decreased the level of pro-inflammatory factors (TNF-alpha, IL-1beta)/CD68+ cells and increased the level of anti inflammatory factors (IL-4, IL-10)/CD163+ cells compared with the control group. Combined the bioinformatics analyses/luciferase assay with the promoting effect of H19 shRNA on the expression of miR-130b, we speculated that miR-130b was a target of H19 in ox-LDL-treated Raw264.7 cells. Moreover, the adding of LncRNA H19 abolished the facilitating effect of miR-130b inhibitor on adipogenesis and inflammation response by up-regulating the expression of miR-130b. Taken together, our research indicated a H19-miR130b pathway in regulating lipid metabolism and inflammation response in ox-LDL-treated Raw264.7 cells, providing new targets for AS treatment. PMID- 29172089 TI - Retargeted and detargeted adenovirus for gene delivery to the muscle. AB - We previously selected muscle binding peptides 12.51 and 12.52 from "context specific" phage display libraries for introduction into adenovirus (Ad) vectors. In this work, these peptides were inserted into the hypervariable region (HVR) 5 loop of the Ad5 hexon protein to display 720 peptides per virions. HVR-12.51 and 12.52 increased transduction of C2C12 cells up to 20-fold when compared to unmodified Ad5. 12.51 increased in vivo muscle transduction 2 to 7-fold over unmodified Ad after intramuscular injection in mice and hamsters. 12.52 did not increase muscle transduction. Notably, insertion of 12.51 into the hexon reduced liver transduction 80-fold when compared to unmodified Ad5 after intravenous injection. Increased muscle transduction in mice translated into increased immune responses after gene-based vaccination. These data suggest there are merits to retargeting and detargeting benefits to modifying the hexons of Ads with peptide ligands. PMID- 29172091 TI - Neural mechanisms of movement planning: motor cortex and beyond. AB - Neurons in motor cortex and connected brain regions fire in anticipation of specific movements, long before movement occurs. This neural activity reflects internal processes by which the brain plans and executes volitional movements. The study of motor planning offers an opportunity to understand how the structure and dynamics of neural circuits support persistent internal states and how these states influence behavior. Recent advances in large-scale neural recordings are beginning to decipher the relationship of the dynamics of populations of neurons during motor planning and movements. New behavioral tasks in rodents, together with quantified perturbations, link dynamics in specific nodes of neural circuits to behavior. These studies reveal a neural network distributed across multiple brain regions that collectively supports motor planning. We review recent advances and highlight areas where further work is needed to achieve a deeper understanding of the mechanisms underlying motor planning and related cognitive processes. PMID- 29172090 TI - Nutritional status and diet as predictors of children's lead concentrations in blood and urine. AB - Lead exposure remains an important public health problem. Contaminated foods may act as a source of lead exposure, while certain nutrients may reduce lead absorption. We examined the cross-sectional associations of dietary patterns and the intake of several nutrients and foods with blood (Pb-B) and urinary (Pb-U) lead concentrations in children (5-8y) from Montevideo, Uruguay. From two 24-hour recalls completed by caregivers, we derived the mean daily intake of select nutrients and food groups (dairy, milk, fruit, root vegetables, foods rich in heme and non-heme iron), as well as "nutrient dense" and "processed" food patterns. Pb-B (n=315) was measured using atomic absorption spectrometry; Pb-U (n=321) using ICP-MS. Pb-U was adjusted for specific gravity and log-transformed to approximate a normal distribution. Iron deficiency (ID) and dietary variables were tested as predictors of Pb-B and log-Pb-U in covariate-adjusted regressions. Median [5%, 95%] Pb-B and Pb-U were 3.8 [0.8-7.8] MUg/dL and 1.9 [0.6-5.1] MUg/L, respectively; ~25% of Pb-B above current U.S. CDC reference concentration of 5MUg/dL. ID was associated with 0.75MUg/dL higher Pb-B, compared to non-ID (p<0.05). Consumption of root vegetables was not associated with Pb-B or log-Pb U. Higher scores on the nutrient-dense pattern were related with higher Pb-Bs, possibly due to consumption of green leafy vegetables. Dietary intake of iron or iron-rich foods was not associated with biomarkers of lead. Conversely, children consuming more calcium, dairy, milk and yogurt had lower Pb-B and log-Pb-U. Our findings appear consistent with existing recommendations on including calcium rich, but not iron- or vitamin-C-rich foods in the diets of lead-exposed children, especially where the consumption of these foods is low. PMID- 29172092 TI - Visual field defects after temporal lobe resection for epilepsy. AB - PURPOSE: To determine visual field defects (VFDs) using methods of varying complexity and compare results with subjective symptoms in a population of newly operated temporal lobe epilepsy patients. METHODS: Forty patients were included in the study. Two patients failed to perform VFD testing. Humphrey Field Analyzer (HFA) perimetry was used as the gold standard test to detect VFDs. All patients performed a web-based visual field test called Damato Multifixation Campimetry Online (DMCO). A bedside confrontation visual field examination ad modum Donders was extracted from the medical records in 27/38 patients. All participants had a consultation by an ophthalmologist. A questionnaire described the subjective complaints. REULTS: A VFD in the upper quadrant was demonstrated with HFA in 29 (76%) of the 38 patients after surgery. In 27 patients tested ad modum Donders, the sensitivity of detecting a VFD was 13%. Eight patients (21%) had a severe VFD similar to a quadrant anopia, thus, questioning their permission to drive a car. In this group of patients, a VFD was demonstrated in one of five (sensitivity=20%) ad modum Donders and in seven of eight (sensitivity=88%) with DMCO. Subjective symptoms were only reported by 28% of the patients with a VFD and in two of eight (sensitivity=25%) with a severe VFD. Most patients (86%) considered VFD information mandatory. CONCLUSION: VFD continue to be a frequent adverse event after epilepsy surgery in the medial temporal lobe and may affect the permission to drive a car in at least one in five patients. Subjective symptoms and bedside visual field testing ad modum Donders are not sensitive to detect even a severe VFD. Newly developed web-based visual field test methods appear sensitive to detect a severe VFD but perimetry remains the golden standard for determining if visual standards for driving is fulfilled. Patients consider VFD information as mandatory. PMID- 29172094 TI - Familial temporal lobe epilepsy in the 19th century. AB - PURPOSE: To draw attention to a publication showing that familial temporal lobe epilepsy had been described in 1895, considerably earlier than 1994, usually thought to be the date of the original account of the disorder METHODS: Examination of the contents of Sir James Crichton-Browne's Cavendish lecture on 'Dreamy mental states' that was published in the Lancet in mid-1895 RESULTS: At a time when the clinical phenomena that later became associated with the idea of temporal lobe epilepsy were beginning to become known, Creighton-Browne described the presence of this disorder in members of four consecutive generations of a British family throughout the course of the 19th Century CONCLUSIONS: There is evidence that the genetic abnormality responsible for familial temporal epilepsy had probably appeared considerably earlier than hitherto thought. PMID- 29172093 TI - Quantification of perivascular spaces at 7T: A potential MRI biomarker for epilepsy. AB - PURPOSE: 7T (7T) magnetic resonance imaging (MRI) facilitates the visualization of the brain with resolution and contrast beyond what is available at conventional clinical field strengths, enabling improved detection and quantification of small structural features such as perivascular spaces (PVSs). The distribution of PVSs, detected in vivo at 7T, may act as a biomarker for the effects of epilepsy. In this work, we systematically quantify the PVSs in the brains of epilepsy patients and compare them to healthy controls. METHODS: T2 weighted turbo spin echo images were obtained at 7T on 21 epilepsy patients and 17 healthy controls. For all subjects, PVSs were manually marked on Osirix image analysis software. Marked PVSs with diameter>=0.5mm were then mapped by hemisphere and lobe. The asymmetry index (AI) was calculated for each region and the maximum asymmetry index (|AImax|) was reported for each subject. The asymmetry in epilepsy subjects was compared to that of controls, and the region with highest asymmetry was compared to the suspected seizure onset zone. RESULTS: There was a significant difference between the |AImax| in epilepsy subjects and in controls (p=0.016). In 72% of patients, the region or lobe of the brain showing maximum PVS asymmetry was the same as the region containing the suspected seizure onset zone. CONCLUSION: These findings suggest that epilepsy may be associated with significantly asymmetric distribution of PVSs in the brain. Furthermore, the region of maximal asymmetry of the PVSs may help provide localization or confirmation of the seizure onset zone. PMID- 29172095 TI - Innovations and pitfalls in the use of wearable devices in the prevention and rehabilitation of running related injuries. AB - Running-related injuries are common and are associated with a high rate of reoccurrence. Biomechanics and errors in applied training loads are often cited as causes of running-related injuries. Clinicians and runners are beginning to utilize wearable technologies to quantify biomechanics and training loads with the hope of reducing the incidence of running-related injuries. Wearable devices can objectively assess biomechanics and training loads in runners, yet guidelines for their use by clinicians and runners are not currently available. This article outlines several applications for the use of wearable devices in the prevention and rehabilitation of running-related injuries. Applications for monitoring of training loads, running biomechanics, running epidemiology, return to running programs and gait retraining are discussed. Best-practices for choosing and use of wearables are described to provide guidelines for clinicians and runners. Finally, future applications are outlined for this rapidly developing field. PMID- 29172096 TI - Serum agouti-related protein (AgRP) levels in bipolar disorder: Could AgRP be a state marker for mania? AB - Orexigenic and anorexigenic peptides, especially agouti-related protein (AgRP) and leptin, play important roles in the regulation of energy homeostasis in bipolar disorder. AgRP regulates energy metabolism by increasing appetite and decreasing energy expenditure. The resting energy expenditures of patients with manic bipolar disorder are higher than those of controls. Due to the effects of AgRP on energy expenditure and the increased physical activity of manic patients, we hypothesised that serum AgRP levels may be lower in manic patients than in euthymic patients and controls. There was a total of 112 participants, including 47 patients in the manic group, 35 patients in the euthymic group and 30 healthy controls. For this study, serum AgRP, leptin, cholesterol, and cortisol levels were measured and compared between the groups. The serum AgRP, leptin, and cholesterol levels were significantly different between the groups. The serum AgRP levels of manic group were significantly lower than those of euthymic and control groups. The lower serum AgRP levels of manic patients could be indicators of impaired energy homeostasis during manic episodes. Since the serum AgRP levels of manic patients are lower than those of euthymic patients and controls, AgRP could be a state marker for manic episodes. PMID- 29172097 TI - Statin add-on therapy in the antipsychotic treatment of schizophrenia: A meta analysis. AB - A comprehensive meta-analysis of statin add-on therapy in the antipsychotic treatment of schizophrenia was conducted. Data from previous studies, prior to 8/21/2017, was obtained from Scopus, PubMed, PsycINFO, and Cochrane Library. Both a systematic review and meta-analysis were conducted with patient data from randomized placebo-controlled trials (RCTs) to compare statins with placebo in order to calculate effect size. Across the five RCTs (mean duration: 9.2 weeks), 236 adult patients with schizophrenia were randomly selected to receive either placebo (n=117) or statins (n=119). Pooled statin add-on therapy showed significant superiority over placebo in the improvement of Positive and Negative Syndrome Scale (PANSS) total scores (mean difference=-1.96; 95% confidence interval, -2.94 to -0.98; p<0.0001; I2=0%; N=4, n=174). However, there were no statistically significant differences in other efficacy outcomes between the two treatment groups. Statin did not have a significant difference in its incidence of discontinuation or have individual adverse events compared to placebo. Our results suggest that statins may have considerable potential as an add-on therapy for schizophrenia. However, determining the effectiveness of this treatment in clinical practice requires future investigation due to limitations of the current evidence-base including small sample, potential for publication and selection biases and short duration of follow-up. PMID- 29172098 TI - Social defeat as a mediator of the relationship between childhood trauma and paranoid ideation. AB - Social defeat, the subjective experience of viewing oneself as a failure or social outsider, is associated with various psychiatric disorders. Recent studies suggest that social defeat may play an important role in the development of psychotic disorders. This study examined the role of social defeat in the relationship between childhood trauma and paranoid ideation, a symptom of psychosis, in non-psychotic mental disorders. Psychiatric patients (N = 199) completed the Korean version of the Childhood Trauma Questionnaire, the Korean version of the Defeat Scale, and Restructured Clinical Scale 6 (Ideas of Persecution) of the Korean version of the Minnesota Multiphasic Personality Inventory-2. A partial correlation analysis revealed that childhood trauma was significantly related to social defeat and paranoid ideation after controlling for age and gender. Structural equation modeling confirmed that the relationship between childhood trauma and paranoid ideation was partially mediated by social defeat. Thus, social defeat is a possible psychological mechanism underlying the association between childhood trauma and paranoia. PMID- 29172099 TI - Associations between ADHD and eating disorders in relation to comorbid psychiatric disorders in a nationally representative sample. AB - The objective of this study was to examine whether previously observed associations of attention-deficit/hyperactivity disorder (ADHD) with eating disorders (EDs) are at least partially attributable to other underlying psychopathology. Data came from 4719 participants aged 18-44 years in the National Comorbidity Survey Replication and the National Survey of American Life. DSM-IV diagnoses were assessed using the World Health Organization Composite International Diagnostic Interview. Multinomial logistic regression assessed associations between DSM-IV lifetime and past-12 month diagnoses of ADHD with EDs in unadjusted models and in models adjusted for demographic variables and other psychopathology. Lifetime ADHD was strongly and significantly associated with lifetime bulimia nervosa (BN), binge eating disorder (BED), and any ED in unadjusted models, but not with anorexia nervosa or subthreshold BED. After adjusting for demographic variables and psychiatric comorbidities, all associations of lifetime ADHD with EDs were substantially attenuated, and only the association of ADHD with BN remained statistically significant. Similar results were found using past-12 month diagnoses. These results suggest that previously observed associations of ADHD with EDs might be due - at least in part - to additional psychiatric disorders that are often comorbid with both ADHD and EDs. PMID- 29172100 TI - Social identities and shared realities. AB - People are fundamentally motivated to establish a shared reality with others to validate their identity and experiences. Guided by social identity theory, we examine how social identity processes, such as self-categorization and depersonalization, create a shared identity and a sense of shared reality. Research demonstrates that internal states such as attitudes, feelings, and emotions are often shared among members of a group. Furthermore, research has shown that self-uncertainty motivates people to establish shared realities through group identification, often with highly entitative groups that are associated with a self-saturating reality that is shared absolutely. Finally, we review research on how group-defining norms that serve as the bases of these identity-related shared realities are constructed and communicated through group membership based influence. PMID- 29172101 TI - Design, synthesis and evaluation of resveratrol-indazole hybrids as novel monoamine oxidases inhibitors with amyloid-beta aggregation inhibition. AB - Novel hybrids with MAO and Abeta (1-42) self-aggregation inhibitory activities were designed and synthesized with the employment of indazole moiety and resveratrol. The biological screening results indicated that most compounds displayed potent inhibitory activity for Abeta (1-42) self-aggregation, and obvious selective inhibition to MAO-B. Among these compounds, compound 6e was the most potent inhibitor not only for hMAO-B (IC50 = 1.14 MUM) but also for Abeta (1 42) self-aggregation (58.9% at 20 MUM). Molecular modeling and kinetic studies revealed that compound 6e was a competitive MAO-B inhibitor, which can occupy the active site of MAO-B, and interact with Abeta (1-42) via pi-pi and cation-pi stacking interactions. In addition, compound 6e had no toxicity on PC12 cells and could cross the BBB. Collectively, all these results suggested that compound 6e might be a promising multi-target lead compound worthy of further investigation. PMID- 29172102 TI - Influence of salicylic acid pretreatment on seeds germination and some defence mechanisms of Zea mays plants under copper stress. AB - The study was focused on the influence of salicylic acid (SA) on maize seeds germination and on some physiological and biochemical processes in maize plants growing in the hydroponic culture under copper (Cu) stress. A significant influence of SA pretreatment on the advanced induction of the maize seeds metabolic activity and the level of the endogenous SA in germinated seeds and developing roots have been stated. Although, the ability of maize seeds to uptake SA and accumulate it in the germinated roots was confirmed, the growth inhibition of Cu-stressed maize seedlings was not ameliorated by SA seeds pretreatment. Cu stressed plants exhibited a decrease in the photosynthetic pigment concentration and the increase in non-photochemical quenching (NPQ) - an indicator of an excess energy in PSII antenna assemblies lost as a heat. The amelioration effect of SA application was found only for carotenoids content which increased in stressed plants. It was also shown that maize roots growing in stress conditions significantly differed in the chemical composition in comparison to the roots of control plants, but the SA pretreatment did not affect these differences. On the other hand, it was found that SA seed pretreatment significantly influenced the ability of stressed plants to accumulate copper in the roots. It was stated that a higher level of exogenous SA application led to a lower accumulation of Cu ions in maize roots. Cu-stressed plants exhibited higher oxidative stress in roots than in leaves which was manifested as an increase in the concentration of hydrogen peroxide due to stress factor application. We observed an increase in catalase (CAT) activity in leaves of Cu-stressed plants which corresponded with a lower H2O2 content when compared with roots where the hydrogen peroxide level was higher, and the inhibition of the CAT activity was found. Furthermore, we found that the SA seed pretreatment led to a decrease in the H2O2 content in the roots of the Cu-stressed plants, but it did not influence the H2O2 level in leaves. The increase in hydrogen peroxide content in the roots of Cu-stressed plants correlated with a higher activity of the MnSODI and MnSODII isoforms. It was found that SA pretreatment caused a decrease in MnSODII activity accompanied by the decrease in H2O2 concentration. Achieved results indicated also that the changes in the chemical composition of the root tissue under copper stress constituted protection mechanisms of blocking copper flow into other plant organs. However, it might be assumed that the root tissue remodelling under Cu stress did not only prevent against the Cu ions uptake but also limited the absorption of minerals required for the normal growth leading to the inhibition of the plant development. PMID- 29172103 TI - Effect of cold stress on oxidative damage and mitochondrial respiratory properties in chickpea. AB - The present work aimed to characterize some of the mitochondrial and defense responses involved in tolerance to cold stress (CS) in tolerant (Sel96Th11439) and sensitive (ILC533) chickpea (Cicer arietinum L.) genotypes. During CS, the tolerant genotype prevented the H2O2 accumulation significantly; led to a decrease in electrolyte leakage index (ELI), which was a sign of relative acclimation of this genotype compared to sensitive one. A significant positive correlation between ELI and H2O2 (r0.01 = 0.86) content confirmed these results. Under cold, a significant increase in the alternative oxidase (AOX) activity was observed in tolerant genotype compared to sensitive one. In parallel, the high activity of superoxide dismutase (SOD) accompanied with catalase (CAT) and ascorbate peroxidase (APX) activities and also the extreme amounts of ascorbate and proline certified the active reactive oxygen species (ROS)-scavenging systems. There was a significant negative correlation between damage indices like H2O2 content and the activity of AOX (r0.01 = -0.79) as well as significant positive correlation between AOX activity with CAT (r0.05 = 0.61), SOD (r0.05 = 0.51) and APX activity (r0.05 = 0.52). The increasing succinate dehydrogenase (CaSDH), CaAOX and cytochrome c oxidase (CaCOX) gene expression showed an enhancing response of respiration under CS in tolerant plants compared to sensitive ones. The increasing trend of phosphoenol pyruvate carboxylase (PEPC) activity in tolerant genotype particularly in the sixth day of CS indicated the recovered performance of metabolism pathways. Therefore, the increase of AOX activity along with other defensive mechanisms could be coordinately related to cold tolerance mechanisms in order to alleviate cold-induced oxidative stress in chickpea.

AB - Some Rumex species such as sorrel are edible as baby leaf salad greens. On the other hand, Rumex plants accumulate soluble oxalate, a toxic metabolite which causes serious diseases such as renal syndrome. We attempted to produce low oxalate plants of R. obtusifolius, a perennial weed which has higher vitamin C and amino acid content and higher tolerance to stress than many other Rumex species. Ion beams are ionising radiation with high linear energy transfer that causes a wide spectrum of mutations. Thus, in the present study we evaluated the effects of ion beams on oxalate and other primary metabolites in leaves of R. obtusifolius using CE-MS. The results showed that oxalate content was increased by irradiation with carbon ion beams. Metabolome analysis revealed that ion beams affected carbon flow to the isocitrate pathway, which is involved in oxalate synthesis. These observations suggested that modulation of carbon flow to the isocitrate pathway is important to regulate oxalate levels in plants.

AB - We report five experiments using the picture-word task to examine lexical selection by comparing the effects of translation distractors in bilinguals and synonym distractors in monolinguals. Three groups of bilinguals named objects in their L1 or L2, and English monolinguals named objects using common names (e.g., DOG="dog") or, in a novel manipulation, using synonymous alternative names (e.g., DOG="hound", GLASSES="spectacles"). All studies produced strikingly similar results. When bilinguals named in L1, there was a small facilitation effect from translation distractors, but larger facilitation when they named in L2. When monolinguals produced common names, there was no reliable effect from synonym distractors, but facilitation when they produced alternative names. (There were also strong identity facilitation effects in all naming conditions.) We discuss the relevance of these results for the debate concerning the role of competition in lexical selection and propose that for speech production there are direct facilitatory connections between the lexical representations of translations in bilinguals (and between synonyms in monolinguals). The effects of synonyms in monolinguals appear to "simulate" the effects found for translations in bilinguals, which suggest that there are commonalities in monolingual and bilingual lexical selection.

AB - BACKGROUND: Throughout the first two years of college, the majority of drinkers experience one or more alcohol-related consequences. Research that examines the characteristics surrounding negative consequences typically utilizes global retrospective survey methods. The objective of the current study was to apply an event-based methodology to describe the circumstances of a recent drinking episode that resulted in one or more alcohol-related consequences among first- and second-year college students. METHODS: We used a prospective web-based survey method to identify participants (N=296) who had one or more alcohol-related consequences in the past week. Shortly after reporting the consequence(s), participants attended an in-person interview during which they described the circumstances that preceded and followed the consequence(s), including the use of alcohol and other substances, proximal contextual factors including peer drinking, the characteristics of the negative alcohol-related consequence(s), and the reaction of others to the event. RESULTS: The majority of participants reported experiencing the event at either their own (32.4%) or a friend's (32.8%) residence, and 87.1% of participants were with peers when the event happened. Most (85.0%) of the sample indicated that their closest friend knew about their event. CONCLUSION: The high peer involvement at all stages of the event suggest the potential for training college students to help each other avoid or prevent consequences.

AB - Given the increasing interest in alternative processes for producing biodiesel, we focused on the latest screening of lipases and bioprocess design using multiple feedstocks. The implementation of lipase technology to the biodiesel industry is in the early stages. However, current research has made phenomenal advances in generating lipase variants and in engineering biodiesel production. The structural insights into lipase stability, together with primary screening, have opened up opportunities for acquiring lipase variants that are highly tolerant under industrially relevant conditions. The versatility of lipases is promising for process intensification, where time-consuming and costly steps can possibly be avoided. To judiciously overcome uncertainties in the biodiesel industry, further research on technology development integrated with supply chain models is necessary. PMID- 29172109 TI - The oral glucose test predicts laminitis risk in ponies fed a diet high in nonstructural carbohydrates. AB - The aim of this study was to investigate the relationship between laminitis development in ponies and insulin/glucose concentrations in response to the oral glucose test (OGT) and a dietary challenge high in nonstructural carbohydrates (NSCs). After undergoing an OGT (1 g dextrose/kg BW in feed), 37 ponies with 2-h serum insulin concentrations ranging from 22 to 1,133 MUIU/mL were subjected to a diet challenge period (DCP), consuming 12 g NSC/kg BW/d for up to 18 d. Insulin and glucose responses were measured on day 2 of the DCP. Clinical laminitis was diagnosed by blinded experts and confirmed radiographically. Basal ACTH levels and clinical signs were assessed to investigate concurrent putative pituitary pars intermedia dysfunction (PPID). The diet induced Obel grade 1 or 2 laminitis in 14 ponies (38%). The ponies that developed laminitis had higher maximum concentrations of blood glucose (P = 0.04) and serum insulin (P = 0.02) in response to the diet. The geometric mean (95% CI) blood glucose concentration for laminitis cases was 14.9 (12.9-17.2) mM, compared to 10.7 (9.2-12.5) mM for ponies who did not develop laminitis. Similarly, the geometric mean (95% CI) for serum insulin was 396 (301-520) MUIU/mL for laminitis cases, compared to 216 (148 316) MUIU/mL for ponies who did not develop laminitis. Laminitis incidence was likewise associated with insulin concentrations measured during the OGT. Laminitis occurred at frequencies of 0% (0/7) if postdextrose insulin (MUIU/mL) was <50; 35% (8/23) if insulin was 50 to 195; and 86% (6/7) if insulin was >195 MUIU/mL. Basal ACTH concentrations were above seasonally accepted reference ranges in 16/37 ponies, and 8 of these animals (50%) developed laminitis. This included all 5 ponies in the study that had clinical signs of PPID (100%). In contrast, hyperinsulinemia and laminitis occurred in only 3/11 ponies (27%) with elevated ACTH concentrations and no clinical signs of PPID (P = 0.009). Thus, laminitis occurrence was associated with higher glucose and insulin responses to both the OGT and challenge diet, and the frequency of laminitis can be predicted based on insulin and glucose hyperresponsiveness to these oral carbohydrate challenges. PMID- 29172107 TI - Immune responses in influenza A virus and human coronavirus infections: an ongoing battle between the virus and host. AB - Respiratory viruses, especially influenza A viruses and coronaviruses such as MERS-CoV, represent continuing global threats to human health. Despite significant advances, much needs to be learned. Recent studies in virology and immunology have improved our understanding of the role of the immune system in protection and in the pathogenesis of these infections and of co-evolution of viruses and their hosts. These findings, together with sophisticated molecular structure analyses, omics tools and computer-based models, have helped delineate the interaction between respiratory viruses and the host immune system, which will facilitate the development of novel treatment strategies and vaccines with enhanced efficacy. PMID- 29172110 TI - Role of luteal biosynthesis of prostaglandin F2alpha on function and structure of the corpus luteum during luteolysis in heifers. AB - The role of endogenous prostaglandin F2alpha (PGF) in the induction of luteolysis by exogenous PGF was studied by simultaneous inhibition of endogenous PGF with flunixin meglumine (FM). Groups were controls (n = 8), PGF treated (n = 8), and FM + PGF treated (n = 9). Treatments were given 10 d postovulation at hours 0, 8, and 16. The protocol was based on (1) the assumption that luteolytic characteristics of exogenous PGF would be altered if the synthesis of endogenous PGF is simultaneously inhibited and (2) the reports that luteolysis involves a direct effect of uterine PGF on large luteal cells followed by an effect of the large cells on the small cells. At hour 48, progesterone concentration was greater in the controls (7.6 +/- 0.8 ng/mL) than that in the FM + PGF group (3.0 +/- 0.5 ng/mL) and lower in the PGF group (0.7 +/- 0.3 ng/mL) than in the FM + PGF group (interaction, P < 0.0001). The effects of each of the 3 groups on percentage change in CL volume were similar to the effects on progesterone. At hour 48, the percentage of CL tissue with color-Doppler signals of blood flow was similar between the controls (56.2% +/- 3.8%) and FM + PGF group (50.0% +/- 6.4%) and lowest in the PGF group (15.6% +/- 7.2%) (interaction, P < 0.0001). A resurgence in progesterone concentration began at hours 24 or 48 in 6 of 9 heifers in the FM + PGF group compared to 0 of 8 heifers in each of the other groups (P < 0.007). The progesterone resurgence in the FM + PGF group was associated with the maintenance of percentage of CL tissue with blood-flow signals. The experimental hypothesis that an inhibitor of endogenous PGF reduces the luteolytic response to exogenous PGF was supported. PMID- 29172111 TI - Influence of dentin pretreatment with 2.5% titanium tetrafluoride on inhibiting caries at the tooth-restoration interface in situ. AB - OBJECTIVE: Investigate the effects of dentin pretreatment with 2.5% titanium tetrafluoride (TiF4) aqueous solution followed by two-step self-etching (CLE/Clearfil SE Bond) and one-step self-etching adhesive systems (SBU/Single Bond Universal) on carious lesion inhibition at the tooth-restoration interface using an in situ model. DESIGN: Sixty-four cavities at the enamel-dentin junction of dental fragments were randomly distributed according to groups (n=16): 1) TiF4+CLE; 2) TiF4+SBU; 3) CLE; 4) SBU. Cavities were restored using resin composite, and placed in intraoral palatal devices used by 16 volunteers for 21days, to induce caries formation in situ. The fragments were then ground-flat to perform Knoop microhardness tests. Nine indentations were performed on each enamel and dentin substrate, subjacent to the restoration. Analysis of variance and Tukey's test were applied. RESULTS: Enamel: groups receiving TiF4 dentin pretreatment (regardless of adhesive system and tooth-restoration interface distance) presented higher hardness means at a depth of 25MUm from the outer tooth surface (p<0.0001). Dentin: groups receiving CLE presented higher means when applying TiF4 pretreatment, whereas groups restored with SBU presented higher means without pretreatment (p=0.0003). CONCLUSIONS: Dentin pretreatment with TiF4 inhibited demineralization of the enamel interface in situ, regardless of the adhesive, and TiF4 pretreatment followed by CLE application showed higher potential for inhibiting dentin demineralization at the interface. PMID- 29172112 TI - Cholesterol-lowering effects of dietary pomegranate extract and inulin in mice fed an obesogenic diet. AB - BACKGROUND: It has been demonstrated in animal studies that both polyphenol-rich pomegranate extract (PomX) and the polysaccharide inulin, ameliorate metabolic changes induced by a high-fat diet, but little is known about the specific mechanisms. OBJECTIVE: This study evaluated the effect of PomX (0.25%) and inulin (9%) alone or in combination on cholesterol and lipid metabolism in mice. METHODS: Male C57BL/6 J mice were fed high-fat/high-sucrose [HF/HS (32% energy from fat, 25% energy from sucrose)] diets supplemented with PomX (0.25%) and inulin (9%) alone or in combination for 4 weeks. At the end of intervention, serum and hepatic cholesterol, triglyceride levels, hepatic gene expression of key regulators of cholesterol and lipid metabolism as well as fecal cholesterol and bile acid excretion were determined. RESULTS: Dietary supplementation of the HF/HS diet with PomX and inulin decreased hepatic and serum total cholesterol. Supplementation with PomX and inulin together resulted in lower hepatic and serum total cholesterol compared to individual treatments. Compared to HF/HS control, PomX increased gene expression of Cyp7a1 and Cyp7b1, key regulators of bile acid synthesis pathways. Inulin decreased gene expression of key regulators of cholesterol de novo synthesis Srebf2 and Hmgcr and significantly increased fecal elimination of total bile acids and neutral sterols. Only PomX in combination with inulin reduced liver and lipid weight significantly compared to the HF/HS control group. PomX showed a trend to decrease liver triglyceride (TG) levels, while inulin or PomX-inulin combination had no effect on either serum or liver TG levels. CONCLUSION: Dietary PomX and inulin supplementation decreased hepatic and serum total cholesterol by different mechanisms and the combination leading to a significant enhancement of the cholesterol-lowering effect. PMID- 29172113 TI - Integrating self-management support for knee injuries into routine clinical practice: TRAK intervention design and delivery. AB - BACKGROUND: TRAK is a web-based intervention that provides knee patients with health information, personalised exercise plans and remote clinical support. The aim of this study was to fully define TRAK intervention content, setting and context and develop the training through an implementation study in a physiotherapy out-patient service. METHODS: A mixed methods study. Phase 1 was a qualitative interview study, whereby fifteen physiotherapists used TRAK for 1 month with a patient of their choice. Interviews explored patient and physiotherapist views of TRAK intervention and training requirements. In Phase 2 seventy-four patients were recruited, all received conventional physiotherapy, a subset of 48 patients used TRAK in addition to conventional Physiotherapy. Aspects of feasibility measured included: uptake and usage of TRAK. RESULTS: Patients and physiotherapists reported that TRAK was easy to use and highlighted the therapeutic benefit of the exercise videos and personalised exercise plans to remind them of their exercises and the correct technique. Patients reported needing to use TRAK with the guidance of their treating physiotherapist initially. Physiotherapists highlighted appointment time constraints and lack of familiarity with TRAK as factors limiting engagement. In Phase 2, 67% patients accessed TRAK outside of the clinical environment. A total of 91% of patients were given a personalised exercise plan, but these were only updated in 34% of cases. CONCLUSION: A comprehensive training package for patients and clinicians has been defined. The refined TRAK intervention is reported using the 'Template for Intervention Description and Replication in preparation for a definitive randomised control trial. PMID- 29172114 TI - Beamforming applied to surface EEG improves ripple visibility. AB - OBJECTIVE: Surface EEG can show epileptiform ripples in people with focal epilepsy, but identification is impeded by the low signal-to-noise ratio of the electrode recordings. We used beamformer-based virtual electrodes to improve ripple identification. METHODS: We analyzed ten minutes of interictal EEG of nine patients with refractory focal epilepsy. EEGs with more than 60 channels and 20 spikes were included. We computed ~79 virtual electrodes using a scalar beamformer and marked ripples (80-250 Hz) co-occurring with spikes in physical and virtual electrodes. Ripple numbers in physical and virtual electrodes were compared, and sensitivity and specificity of ripples for the region of interest (ROI; based on clinical information) were determined. RESULTS: Five patients had ripples in the physical electrodes and eight in the virtual electrodes, with more ripples in virtual than in physical electrodes (101 vs. 57, p = .007). Ripples in virtual electrodes predicted the ROI better than physical electrodes (AUC 0.65 vs. 0.56, p = .03). CONCLUSIONS: Beamforming increased ripple visibility in surface EEG. Virtual ripples predicted the ROI better than physical ripples, although sensitivity was still poor. SIGNIFICANCE: Beamforming can facilitate ripple identification in EEG. Ripple localization needs to be improved to enable its use for presurgical evaluation in people with epilepsy. PMID- 29172115 TI - RLS patients show better nocturnal performance in the Simon task due to diminished visuo-motor priming. AB - OBJECTIVE: The restless legs syndrome (RLS) is characterized by sensory-motor symptoms which usually occur predominantly at rest in the evening and at night. It is assumed that this circadian rhythm is caused by low dopamine levels in the evening. Yet, it has never been investigated whether RLS patients show diurnal variations in cognitive functions modulated by dopamine and what neurophysiological and functional neuroanatomical processes underlie such modulations. METHODS: We used a Simon task combined with EEG and source localization to investigate whether top-down response selection and/or automatic visuo-motor priming are subject to diurnal changes in RLS patients, as compared to matched healthy controls. RESULTS: We found that RLS patients showed better task performance due to reduced visuo-motor priming in the evening, as reflected by smaller early lateralized readiness potential (e-LRP) amplitudes and decreased activation of the superior parietal cortex and premotor cortex. Top-down response selection and early attentional processing were unaffected by RLS. CONCLUSIONS: Counterintuitively, RLS patients show enhanced task performance in the evening, i.e. when experiencing dopaminergic deficiency. Yet, this may be explained by deficits in visuo-motor priming that lead to reduced false response tendencies. SIGNIFICANCE: This study reveals a counterintuitive circadian variation of cognitive functions in RLS patients. PMID- 29172116 TI - Bilateral loss of cortical SEPs predict severe MRI lesions in neonatal hypoxic ischemic encephalopathy treated with hypothermia. AB - OBJECTIVE: The introduction of therapeutic hypothermia for neonatal hypoxic ischemic encephalopathy calls for reevaluation of the prognostic role of somatosensory evoked potentials (SEPs). METHODS: Among 80 consecutive neonates undergoing hypothermia for hypoxic-ischemic encephalopathy, 58 performed SEPs and MRI at 4-14 days of life and were recruited in this multicenter study. SEPs were scored as: 0 (bilaterally/unilaterally recorded N20) or 1 (bilaterally absent N20). The severity of brain injury was scored using MRI. RESULTS: Bilaterally absent N20 was observed in 10/58 neonates (17%); all had moderate/severe MRI abnormalities; 36/48 neonates (75%) with score 0 at SEPs had normal MRI. The positive predictive value of SEPs on MRI outcome was of 1.00, while the negative predictive value 0.72, sensitivity 0.48, specificity 1.00, with an accuracy of 0.78 (p < .001). CONCLUSIONS: Bilateral absence of cortical SEPs predicts moderate/severe MRI pattern of injury. SIGNIFICANCE: Therapeutic hypothermia does not seem to significantly affect prognostic reliability of SEPs. PMID- 29172117 TI - The effect of surfactant adsorption on surface wettability and flow resistance in slit nanopore: A molecular dynamics study. AB - HYPOTHESIS: Due to large surface/volume ratio, fluid flow resistance in nanopores is affected dramatically by surfactants adsorption, which dictates wettability and friction. Surfactants with different aggregated morphology and molecular alignment at solid/water interface are expected to affect friction and mobility of surfactant adsorption layer, both of which should be possible to contribute to surfactant drag reduction mechanism in nanopores. Simulations: Molecular dynamics (MD) simulations were adopted to study the morphology of the adsorption layer of different types of surfactants on negatively charged hydrophilic silica surface and their effect on flow resistance in slit nanopores. FINDINGS: Flow resistance differs as surfactant adsorption morphologies vary. Adsorption layer composed of hemimicelles with "head on" orientation in low adsorption amount exhibits low flow resistance. As adsorption amount increases, adsorption layer evolves into the double layer in which less polar surfactant composition is found to be beneficial for improving hydrophobicity of pore wall and interfacial water diffusion. More ordered and tight intermolecular packing and high mobility of the adsorption layer are found to be propitious to reduce the flow friction. PMID- 29172118 TI - Rational and green synthesis of novel two-dimensional WS2/MoS2 heterojunction via direct exfoliation in ethanol-water targeting advanced visible-light-responsive photocatalytic performance. AB - Two-dimensional transition metal dichalcogenides (2D TMDs) and their heterostructures have by far stimulated growing research interests in the field of optoelectronics and photocatalysis. In this regard, scalable fabrication of 2D TMDs at an environmentally-benign and cost-effective manner via liquid phase exfoliation is a particularly fascinating concept. Herein we report a facile and green strategy to produce few-layered WS2 suspensions at a large scale by a direct exfoliation of commercial WS2 powders in water-ethanol mixtures. In turn, by making full use of the features of 2D layered WS2, a novel 2D WS2/MoS2 composite was constructed for the first time via an in-situ hydrothermal reaction to grow MoS2 nanoflakes onto few-layered WS2 basal planes. The as-obtained WS2/MoS2 heterostructure was investigated for photocatalytic applications. Such a hybrid material demonstrated superior photocatalytic activity in the photocatalysis of organic dye molecules relative to that of pristine 2D WS2, MoS2 and their physical mixtures. This enhancement was associated with the 2D WS2/MoS2 heterostructuring effect. In addition, comparisons of the photocatalytic performances of our heterojunctions with those of recently reported 2D TMD-based hybrid materials manifested a significantly higher efficiency. PMID- 29172119 TI - Assembling particle clusters with incoherent 3D magnetic fields. AB - Directed assembly of particle suspensions in massively parallel formats, such as with magnetic fields, has application in rheological control, smart drug delivery, and active colloidal devices from optical materials to microfluidics. At the heart of these applications lies a control optimization problem for driving the assembly and dissolution of highly monodisperse particle clusters. For magnetic field control, most attention to-date has been centered around in phase coherent magnetic fields. Instead, we investigate a family of incoherent 3D magnetic fields that are capable of creating controlled and tunable particle assemblies such as dimers, trimers, and quadramers. These field functions can be tuned to assemble monodisperse clusters with long term stability and can quickly switch the clusters between different states. This subset of three-dimensional field functions that we have studied demonstrates the rich phase space available to tune colloidal suspensions with magnetic fields. PMID- 29172120 TI - 18F-labeled norepinephrine transporter tracer [18F]NS12137: radiosynthesis and preclinical evaluation. AB - INTRODUCTION: Several psychiatric and neurodegenerative diseases are associated with malfunction of brain norepinephrine transporter (NET). However, current clinical evaluations of NET function are limited by the lack of sufficiently sensitive methods of detection. To this end, we have synthesized exo-3-[(6 [18F]fluoro-2-pyridyl)oxy]-8-azabicyclo[3.2.1]-octane ([18F]NS12137) as a radiotracer for positron emission tomography (PET) and have demonstrated that it is highly specific for in vivo detection of NET-rich regions of rat brain tissue. METHODS: We applied two methods of electrophilic, aromatic radiofluorination of the precursor molecule, exo-3-[(6-trimethylstannyl-2-pyridyl)oxy]-8-azabicyclo [3.2.1]octane-8-carboxylate: (1) direct labeling with [18F]F2, and (2) labeling with [18F]Selectfluor, a derivative of [18F]F2, using post-target produced [18F]F2. The time-dependent distribution of [18F]NS12137 in brain tissue of healthy, adult Sprague-Dawley rats was determined by ex vivo autoradiography. The specificity of [18F]NS12137 binding was demonstrated on the basis of competitive binding by nisoxetine, a known NET antagonist of high specificity. RESULTS: [18F]NS12137 was successfully synthesized with radiochemical yields of 3.9% +/- 0.3% when labeled with [18F]F2 and 10.2% +/- 2.7% when labeled with [18F]Selectfluor. The molar activity of radiotracer was 8.8 +/- 0.7 GBq/MUmol with [18F]F2 labeling and 6.9 +/- 0.4 GBq/MUmol with [18F]Selectfluor labeling at the end of synthesis of [18F]NS12137. Uptake of [18F]NS12137 in NET-rich areas in rat brain was demonstrated with the locus coeruleus (LCoe) having the highest regional uptake. Prior treatment of rats with nisoxetine showed no detectable [18F]NS12137 in the LCoe. Analyses of whole brain samples for radiometabolites showed only the parent compound [18F]NS12137. Uptake of 18F-radioactivity in bone increased with time. CONCLUSIONS: The two electrophilic 18F-labeling methods proved to be suitable for synthesis of [18F]NS12137 with the [18F]Selectfluor method providing an approximate three-fold higher yield than the [18F]F2 method. As an electrostatically neutral radiotracer [18F]NS12137 crosses the blood-brain barrier and enabled specific labeling of NET-rich regions of rat brain tissue with the highest concentration in the LCoe. PMID- 29172121 TI - Marijuana use is associated with hypersensitivity to multiple allergens in US adults. AB - BACKGROUND: The recent legalization of marijuana use for both medical and recreational purposes in several states of the United Sates is expected to further increase the already high prevalence of marijuana use. Although allergic reactions are uncommon, the potential of marijuana use and cultivation to cause allergy should be considered. We aimed to investigate whether marijuana use is associated with the prevalence of sensitization to specific allergens. METHODS: A total of 2671 adults (aged 20-59 years) who participated in the 2005-2006 National Health and Nutrition Examination Survey were included. Participants completed a questionnaire on marijuana use and underwent sensitization tests to 19 specific allergens. Those who reported marijuana use for at least 1 day in the past 30 days were considered marijuana users. RESULTS: No difference was found in the history of allergy between marijuana users and non-users. Compared with marijuana non-users as a reference group, the adjusted odds ratio (AOR) of sensitization to a specific allergen among marijuana users was significantly greater for antibodies against the following: Alternaria alternata (AOR=1.67; 95% confidence interval (CI), 1.04-2.70), D. farinae (AOR=1.68; 95% CI, 1.27-2.22), D. pteronyssin (AOR=1.65; 95% CI, 1.32-2.06), ragweed (AOR=1.84; 95% CI, 1.30 2.59), rye grass (AOR=1.49; 95% CI, 1.12-1.97), Bermuda grass (AOR=1.55; 95% CI, 1.03-2.33), oak (AOR=1.76; 95% CI, 1.14-2.70), birch (AOR=2.09; 95% CI, 1.23 3.55), peanut (AOR=1.91; 95% CI, 1.25-2.92), and cat dander (AOR=1.51; 95% CI=1.13-2.03). CONCLUSIONS: We provide preliminary findings to suggest that marijuana use is associated with sensitization to specific allergens, including molds, dust mites, plants, and cat dander. PMID- 29172122 TI - Brain substrates of early (4h) cigarette abstinence: Identification of treatment targets. AB - INTRODUCTION: Research indicates that overnight nicotine abstinence disrupts neural activity in the mesocorticolimbic reward network; however, less is known about the time course of abstinence-induced brain changes. To examine the potential neural effects of early abstinence, we used arterial spin labeling perfusion fMRI, to measure regional cerebral blood flow (rCBF) changes in the resting brain induced by 4h of nicotine abstinence. METHODS: In a repeated measures design, 5min of resting perfusion fMRI data were acquired in awake nicotine-dependent individuals (eyes open) during 'smoking as usual' (SMK) and following 4h of monitored nicotine abstinence (ABS) conditions (N=20). Conditions were compared using a paired t test in SPM8. Craving was assessed prior to each condition. RESULTS: Compared to SMK, ABS significantly increased craving and reduced rCBF in select regions, including the hippocampus and ventral striatum (cluster corr, alpha=0.01, 943 contiguous voxels). The magnitude of the abstinence-induced change in rCBF correlated with the magnitude of the change in craving across conditions in select regions, including the medial and lateral orbitofrontal cortices and the anterior ventral insula (r values ranging from 0.59-0.74). CONCLUSIONS: Results show that as few as 4h of abstinence can reduce resting rCBF in multiple nodes of the brain's mesocorticolimbic network, disrupting neural processing. Identifying early withdrawal treatment targets has far-reaching implications, which include thwarting relapse proclivities. Results parallel those of the extant human literature and are in agreement with an extensive preclinical literature showing compromised mesolimbic dopaminergic function and impairments in reward function during nicotine withdrawal. PMID- 29172124 TI - Material mapping strategy to improve the predicted response of the proximal femur to a sideways fall impact. AB - Sideways falls are largely responsible for the highly prevalent osteoporotic hip fractures in today's society. These injuries are dynamic events, therefore dynamic FE models validated with dynamic ex vivo experiments provide a more realistic simulation than simple quasi-static analysis. Drop tower experiments using cadaveric specimens were used to identify the material mapping strategy that provided the most realistic mechanical response under impact loading. The present study tested the addition of compression-tension asymmetry, tensile bone damage, and cortical-specific strain rate dependency to the material mapping strategy of fifteen dynamic FE models of the proximal femur, and found improved correlations and reduced error for whole bone stiffness (R2 = 0.54, RSME = 0.87kN/mm) and absolute maximum force (R2 = 0.56, RSME =0.57kN), and a high correlation in impulse response (R2 = 0.82, RSME =12.38kg/s). Simulations using fully bonded nodes between the rigid bottom plate and PMMA cap supporting the femoral head had higher correlations and less error than simulations using a frictionless sliding at this contact surface. Strain rates over 100/s were observed in certain elements in the femoral neck and trochanter, indicating that additional research is required to better quantify the strain rate dependencies of both trabecular and cortical bone at these strain rates. These results represent the current benchmark in dynamic FE modeling of the proximal femur in sideways falls. Future work should also investigate improvements in experimental validation techniques by developing better displacement measurements and by enhancing the biofidelity of the impact loading wherever possible. PMID- 29172123 TI - Existing and emerging therapies for managing constipation and diarrhea. AB - Functional bowel disorders (i.e., constipation and diarrhea) are characterized by abdominal pain, bloating, distention, and/or bowel habit abnormalities in the absence of obvious anatomic or physiologic abnormalities on routine diagnostic tests. These symptoms are attributable to gastrointestinal sensorimotor dysfunctions resulting from peripheral and/or central mechanisms. Available drugs target the underlying bowel disturbance (i.e., constipation, diarrhea, or both), supplemented when necessary by management of pain. Osmotic and stimulant laxatives, secretagogues, and serotonin 5-HT4 receptor agonists are approved for treating constipation. Loperamide, anticholinergic agents, rifaximin, bile-acid binding agents, eluxadoline, and clonidine are used to treat diarrhea. Several exciting new compounds, some of which have been evaluated in humans, are currently under development. PMID- 29172125 TI - Microtensile bond strength, 4-point bending and nanoleakage of resin-dentin interfaces: Effects of two matrix metalloproteinase inhibitors. AB - Chronic degradation of hybrid layer collagen by matrix metalloproteinases (MMPs) jeopardizes resin-dentin interfacial integrity and limits the durability of dental restorations. The 4-point bending strength (BS) is a valid but uncommon method of testing the mechanical behavior of resin-dentin interfaces. The present study aims to analyze the influence of two matrix metalloproteinase inhibitors on microtensile bond strength (uTBS), BS and nanoleakage. A total of 48M were divided into three groups according to bonding procedure. Teeth were horizontally sectioned to produce a flat dentin surface. In the control group, etch-and-rinse Prime&Bond One (Dentsply) bonding was used; in the self-etch group, methacryloyloxydodecylpyridinium bromide (MDPB)-containing Clearfil SE Protect (Kuraray) was used; and in the benzalkonium chloride (BAC)-etch group, BAC etchant (Bisco) was used. A Ceram.X-One (Dentsply) composite was built as three successive layers and was light-cured. Samples were sectioned to produce microrods that were randomly divided into two groups for analysis at baseline and after 6 months of water immersion (n = 32), plus one slab for nanoleakage analysis (n = 8) via scanning electron microscopy (SEM) and digital image analysis (Fiji). Data were analyzed using the Weibull distribution and a mixed model ANOVA with a post hoc Tukey test. All groups showed deterioration of the initial bonds. The self-etch group had a worse baseline uTBS than the control but had the best BS after aging. BAC-etch did not improve bond stability of etch-and rinse adhesive. The uTBS and BS test results after aging were moderately correlated. Mixed fractures prevailed with regard to uTBS, whereas adhesive fractures dominated with regard to BS. Nanoleakage was not eliminated in any group and increased after aging. MDPB self-etch resisted bond degradation better than etch-and-rinse adhesives, even after BAC-etching. Integrating BS in studies of uTBS and nanoleakage might provide more clinically relevant outcomes for predicting the performance of dental adhesives.

AB - LH601A is a novel non-reactive chiral molecule inhibiting Keap1-Nrf2 protein protein interaction. The absolute configuration (AC) was independently determined in this study using vibrational circular dichroism (VCD) spectroscopy. Because of band overlapping and broadening in the IR spectrum, a direct VCD spectrum comparison method is devised without the conventional IR band alignment. Being an unbiased AC inquiry, all possible chiralities are evaluated based on the statistical analysis of VCD similarity, Sv. The AC of three-center stereoisomer LH601A is unambiguously assigned to (S,R,S). A comparative study was also carried out to investigate the structural and energy differences of calculated conformers using the polarized continuum model of dimethyl sulfoxide.

AB - We aimed to investigate whether 6-O-alpha-maltosyl-beta-cyclodextrin (Mal-betaCD) is incorporated into cells and lysosomes during the release of unesterified cholesterol in Npc1-deficient Chinese hamster ovary (CHO) cells (Npc1 KO cells) and CHO-JP17 cells (JP17 cells). Internalization of Mal-betaCD in cells and lysosomes and extracellular release of lysosomal unesterified cholesterol were demonstrated by LC/MS/MS and LC/MS, respectively. Internalization of Mal-betaCD was greater in Npc1 KO cells than in JP17 cells. The majority of internalized Mal betaCD in both cell types was metabolized by lysosomal alpha-glucosidase to 6-O alpha-D-glucosyl-beta-cyclodextrin (Glc-betaCD). However, Mal-betaCD did not directly enter the lysosomes prepared from cell homogenates. Mal-betaCD-treated Npc1 KO cells and JP17 cells both released Mal-betaCD and Glc-betaCD, together with unesterified cholesterol, out of cells. The release of unesterified cholesterol by Mal-betaCD in Npc1 KO cells was much greater than that in JP17 cells. This study is the first to report the influx of Mal-betaCD into the lysosomes of Npc1 KO cells and JP17 cells, followed by generation of Glc-betaCD, and the efflux of Mal-betaCD/Glc-betaCD and unesterified cholesterol to the extracellular fluid, based on the quantitative LC/MS analysis.

AB - Aggregation of human ocular lens proteins, the crystallins is believed to be one of the key reasons for age-onset cataract. Previous studies have shown that human gammaD-crystallin forms amyloid like fibres under conditions of low pH and elevated temperature. In this article, we have investigated the aggregation propensity of human gammaB-crystallin in absence and presence of epigallocatechin gallate (EGCG), in vitro, when exposed to stressful conditions. We have used different spectroscopic and microscopic techniques to elucidate the inhibitory effect of EGCG towards aggregation. The experimental results have been substantiated by molecular dynamics simulation studies. We have shown that EGCG possesses inhibitory potency against the aggregation of human gammaB-crystallin at low pH and elevated temperature. PMID- 29172129 TI - Effects of two-hour exposure to environmental and high concentrations of methylmercury on the transcriptome of the macrophyte Elodea nuttallii. AB - The effects of two methylmercury (CH3Hg+, MeHg) concentrations, representative of environmental level and extreme contamination, were investigated on the macrophyte Elodea nuttallii during a 2h-exposure combining transcriptomic (RNA Seq), physiological endpoints (pigment contents, activity of anti-oxidative stress enzymes) and bioaccumulation. Exposure to MeHg induced the up- and down regulation of numerous genes (4389 and 16853 for 10ngL-1 and 10MUgL-1 MeHg exposure, respectively) involved in sugar, amino acid and secondary metabolism (e.g. cinnamic acid, flavonoids) at both concentrations. Genes coding for photosynthesis, membrane integrity, metal homeostasis, water transport and anti oxidative enzymes were additionally up- and down-regulated at the higher concentration. At the physiological level, exposure to both MeHg concentrations resulted in a strong increase of anthocyanin content in shoots. Chlorophyll content and antioxidant enzyme activities were unchanged. The data suggest that the macrophyte was able to efficiently cope with the stress resulting from MeHg exposure, possibly by using anthocyanin as anti-oxidant and S-rich amino acids (such as cysteine and methionine) as chelators. Transcriptomics analysis enabled gaining novel insights on molecular effects of MeHg in primary producers, which are one of the main entry pathway of hazardous MeHg in aquatic food webs. PMID- 29172130 TI - Multigenerational effects of 4-methylbenzylidene camphor (4-MBC) on the survival, development and reproduction of the marine copepod Tigriopus japonicus. AB - One of the most widely used organic UV filters, 4-methylbenzylidene camphor (4 MBC), is present at high concentrations in offshore waters. The marine copepod Tigriopus japonicus was exposed to different concentrations of 4-MBC (i.e., 0, 0.5, 1, 5 and 10MUgL-1) for 4 consecutive generations (F0-F3) to evaluate the impact of 4-MBC on marine ecosystems. The results showed that in the F0 generation, 4-MBC caused significant lethal toxicity in T. japonicas at concentrations of 5 and 10MUgL-1 and the nauplii were more sensitive to 4-MBC toxicity than the adults. However in the F1-F3 generations, 4-MBC exposure did not affect the survival rate. The hatching rate and the developmental duration from the nauplii to the copepodite (N-C) and from the nauplii to adult (N-A) decreased significantly in the F1-F2 generations and in the F2-F3 generations, respectively, even at the lowest exposure concentration (0.5MUgL-1). In the subsequent two generations (i.e., the F4-F5 generations) of recovery exposure in clean seawater, the growth rates of the original 4-MBC exposure groups were still faster than the control in both the N-C and N-A stages, suggesting possible transgenerational genetic and/or epigenetic changes upon chronic 4-MBC exposure. The expression of the ecdysone receptor gene was up-regulated by 4-MBC, which was consistent with the decrease of the N-C/N-A duration. In addition, 4-MBC may induce oxidative stress and trigger apoptosis in T. japonicas, resulting in developmental, reproductive and even lethal toxicity. A preliminary risk assessment suggested that under environmentally realistic concentrations, 4-MBC had significant potential to pose a threat to marine crustaceans and marine ecosystems. PMID- 29172131 TI - Nanoteamwork: covalent protein assembly beyond duets towards protein ensembles and orchestras. AB - Biological processes often depend on the harmonious interplay of multiple macromolecules. Biotechnology has had great success in applying and modifying individual components, but the building of multi-component teams is at an early stage. Cells are intelligent in sensing their environment, so manipulating just one signal can limit potency and promote side-effects for therapeutics. Here we critically assess the latest advances in irreversibly connecting individual protein units, through different spontaneous or catalysed reactions. Then we outline efforts to go beyond bipartite assembly, towards multimeric or sequence programmed architectures. These early steps will be put in context of the enormous opportunities for synthetic protein nanomachines, focusing on catalysis and the control of cell signalling for cancer and the immune system. PMID- 29172132 TI - Melatonin pretreatment improves vanadium stress tolerance of watermelon seedlings by reducing vanadium concentration in the leaves and regulating melatonin biosynthesis and antioxidant-related gene expression. AB - Vanadium (V) is an important heavy metal with ubiquitous presence in the Earth's crust, but limited information is available as to its effect on plants and management strategies. Melatonin is a widely studied biomolecule; it acts as an antioxidant and a signaling molecule that enhances the abiotic stress tolerance of plants. Melatonin improves copper, zinc, and cadmium tolerance in plants. In this study, we investigated the response of watermelon seedlings to V stress and the potential role of melatonin in enhancing V stress tolerance of watermelon seedlings. The results showed that seedlings pretreated with melatonin (0.1MUM) exposed to V (50mg/L) had a higher relative chlorophyll content (SPAD index), photosynthetic assimilation, and plant growth compared with non-melatonin pretreated seedlings. Melatonin pretreatment lowered leaf and stem V concentrations by reducing V transport from root to shoot. Melatonin pretreatment enhanced superoxide dismutase (SOD) and catalase (CAT) activities, and reduced the hydrogen peroxide (H2O2) and malondialdehyde (MDA) content of watermelon seedlings, by regulating melatonin biosynthesis and gene expression for superoxide dismutase, peroxidase, ascorbate peroxidase, glutathione peroxidase, and glutathione S-transferase. So far as we know, these results are the first evidence that melatonin improves plant growth of watermelon seedlings under vanadium stress conditions. Considering these observations, melatonin can be utilized to reduce the availability of V to plants, and improve plant growth and V stress tolerance. PMID- 29172133 TI - Cellular imaging and bactericidal mechanism of green-synthesized silver nanoparticles against human pathogenic bacteria. AB - In recent years, silver nanoparticles (AgNPs) have attracted significant attention in medicinal, biomedical, and pharmaceutical research owing to their valuable physicochemical and antibacterial properties. Leaf sap extract (LSE) from Aloe arborescens can be used as an active ingredient for different biological applications, including wound healing. In this study, we have investigated the use of LSE from A. arborescens as a reducing, stabilizing and capping agent to produce AgNPs during the so called "green synthesis" (G-AgNPs). The objective of this study was to prepare, characterize and evaluate the potential of G-AgNPs against human pathogenic bacteria for the intended use as treatment of infected wounds. When the mixture of silver nitrate solution and LSE was exposed to direct sunlight it yielded a rapid color change from colorless to reddish-brown, indicating the formation of G-AgNPs. Physicochemical characterization such as Single particle inductively coupled plasma mass spectrometry, High resolution transmission electron microscopy and surface chemistry studies (Fourier transform infrared spectroscopy and X-Ray diffraction) revealed a small size in the range of 38+/-2nm, smooth surface and existence of LSE on the G-AgNPs. G-AgNPs possessed good antibacterial activity against both Pseudomonas aeruginosa and Staphylococcus aureus. The flow cytometry study revealed the increased percentage of dead cells treated by G-AgNPs through cell membrane damage, and it was further confirmed by confocal laser scanning microscopy. Thus, the present study reveals that the novel G-AgNPs demonstrated effective antibacterial properties against both Gram-negative and Gram-positive bacterial strains and shows great potential for its use in the treatment of pathogen infected wounds. PMID- 29172134 TI - Synthesis, characterisation, cellular uptake and cytotoxicity of functionalised magnetic ruthenium (II) polypyridine complex core-shell nanocomposite. AB - The development of multifunctional nanoparticles comprising of a magnetic core in conjunction with appropriate molecules with capabilities to impart functionalities like luminescent, specific binding sites to facilitate attachment of moieties. This has attracted increasing attention and enables identification of promising candidates using for applications such as diagnostics and cure through early detection and localized delivery. Many studies have been performed on the synthesis and cellular interactions of core-shell nanoparticles, in which a functional inorganic core is coated with a biocompatible polymer layer that should reduce nonspecific uptake and cytotoxicity Here we report the synthesis and characterisation of multifunctional core-shell magnetic, luminescent nanocomposite (Fe3O4@SiO2@[Ru(Phen)3]2+@SiO2@NH2). Fe3O4 as core and a luminescent ruthenium (II) complex encapsulated with silica shell, and then it is functionalized by an amine group by APTMS. The magnetic, luminescent, and biological activity of this multifunctional nanocomposite have also been studied to prove the nanocomposite is biocompatible, cellular uptake. The synthesized nanocomposite was completely characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), and emission spectroscopy. MTT assay and cellular uptake by flow cytometry results proved that magnetic ruthenium (II) polypyridine complex - core shell nanocomposite has biocompatibility, minimum cytotoxicity and internalized inside B16F10 cells and confirms the potential biomedical applications. PMID- 29172135 TI - Potentiation by potassium iodide reveals that the anionic porphyrin TPPS4 is a surprisingly effective photosensitizer for antimicrobial photodynamic inactivation. AB - We recently reported that addition of the non-toxic salt, potassium iodide can potentiate antimicrobial photodynamic inactivation of a broad-spectrum of microorganisms, producing many extra logs of killing. If the photosensitizer (PS) can bind to the microbial cells, then delivering light in the presence of KI produces short-lived reactive iodine species, while if the cells are added after light the killing is caused by molecular iodine produced as a result of singlet oxygen-mediated oxidation of iodide. In an attempt to show the importance of PS bacterial binding, we compared two charged porphyrins, TPPS4 (thought to be anionic and not able to bind to Gram-negative bacteria) and TMPyP4 (considered cationic and well able to bind to bacteria). As expected TPPS4+light did not kill Gram-negative Escherichia coli, but surprisingly when 100mM KI was added, it was highly effective (eradication at 200nM+10J/cm2 of 415nm light). TPPS4 was more effective than TMPyP4 in eradicating the Gram-positive bacteria, methicillin resistant Staphylococcus aureus and the fungal yeast Candida albicans (regardless of KI). TPPS4 was also highly active against E. coli after a centrifugation step when KI was added, suggesting that the supposedly anionic porphyrin bound to bacteria and Candida. This was confirmed by uptake experiments. We compared the phthalocyanine tetrasulfonate derivative (ClAlPCS4), which did not bind to bacteria or allow KI-mediated killing of E. coli after a spin, suggesting it was truly anionic. We conclude that TPPS4 behaves as if it has some cationic character in the presence of bacteria, which may be related to its delivery from suppliers in the form of a dihydrochloride salt. PMID- 29172136 TI - IDH1 and IDH2 mutations in postoperative diffuse glioma-associated epilepsy. AB - OBJECTIVE: Isocitrate dehydrogenase 1 and 2 mutations (IDH1/2) have an established association with preoperative seizures in patients with grades II-IV diffuse gliomas. Here, we examined if IDH1/2 mutations are a biomarker of postoperative seizure frequency. METHODS: This was a retrospective study. Patients with grades II-IV supratentorial diffuse glioma, immunohistochemistry results of IDH1-R132H, and antiepileptic drug (AED) prescribed postoperatively were included. The primary outcome was seizure frequency over the first 12 postoperative months: Group A - postoperative seizure freedom; Group B - 1-11 seizures over 12months (less than one seizure per month); and Group C - greater than one seizure per month. Rates of IDH1-R132H mutation were compared between the three outcome groups in univariate and multivariate analyses. Subgroup analysis was performed in 64 patients with IDH1/2 pyrosequencing data. RESULTS: One hundred cases were included in the analysis: 30.0% grade II, 20.0% grade III, and 50.0% grade IV gliomas. Group B patients averaged 1 seizure over 12months, compared with 2 seizures per month in Group C. Isocitrate dehydrogense 1-R132H mutation was present in 29.3% (17/58) of Group A, 18.2% (14/22) of Group B, and 70.0% (14/20) of Group C patients (p=0.001). On multivariate analysis, after controlling for preoperative seizure, grade, and temporal tumor location, IDH1 R132H was associated with Group C when compared with both Group A (RR 4.75, p=0.032) and Group B (RR 9.70, p=0.012). In the subgroup with IDH1/2 molecular data, an IDH1/2 mutation was present in 64.7% (22/34) of Group A, 28.6% (4/14) of Group C, and 87.5% (14/16) of Group C patients (p=0.004). SIGNIFICANCE: In patients with supratentorial diffuse gliomas, IDH1-R132H mutations are associated with a more severe phenotype of postoperative epilepsy. These findings support further research into IDH mutations, and the potential for an antiepileptic therapeutic effect of their inhibitors, in patients with glioma-associated epilepsy. PMID- 29172137 TI - The impact of stereotactic laser ablation at a typical epilepsy center. AB - PURPOSE: Stereotactic laser ablation (SLA) is a novel form of epilepsy surgery for patients with drug-resistant focal epilepsy. We evaluated one hundred consecutive surgeries performed for patients with epilepsy to address the impact of SLA on our therapeutic approach, as well as patient outcomes. METHODS: A retrospective, single center analysis of the last one hundred neurosurgeries for epilepsy was performed from 2013 to 2015. Demographics, surgical procedures, and postoperative measures were assessed up to 5years to compare the effect of SLA on outcome. Confidence intervals (CI) and comparative tests of proportions compared outcomes for SLA and resective surgery. Procedural categorical comparison used Chi-square and Kaplan-Meier curves. Student t-test was utilized for single variables such as age at procedure and seizure onset. RESULTS: One hundred surgeries for epilepsy yielded thirty-three SLAs and twenty-one resections with a mean of 21.7-month and 21.3-month follow-up, respectively. The temporal lobe was the most common target for SLA (92.6%) and resection (75%). A discrete lesion was present on brain magnetic resonance imaging (MRI) in 27/32 (84.4%) of SLA patients compared with 7/20 (35%) of resection patients with a normal MRI. Overall, 55-60% of patients became seizure-free (SF). Four of five patients with initial failure to SLA became SF with subsequent resection surgery. Complications were more frequent with resection although SF outcomes did not differ (Chi square; p=0.79). Stereotactic laser ablation patients were older than those with resections (47.0years vs. 35.4years, p=0.001). The mean length of hospitalization prior to discharge was shorter for SLA (1.18days) compared with open resection (3.43days; SD: 3.16 days) (p=0.0002). CONCLUSION: We now use SLA as a first line therapy at our center in patients with lesional temporal lobe epilepsy (TLE) before resection. Seizure-free outcome with SLA and resection was similar but with a shorter length of stay. Long-term follow-up is recommended to determine sustained SF status from SLA. PMID- 29172138 TI - Non-epileptic seizures in children: Views and approaches at a UK child and adolescent psychiatry conference. AB - PURPOSE: To describe clinical experiences of paediatric non-epileptic seizures (NES) among doctors attending a UK child and adolescent psychiatry conference. METHODS: Sixty-six participants completed a semi-structured bespoke questionnaire. Results are reported using descriptive statistics. RESULTS: Two thirds of respondents regarded the best name for the disorder to be "non epileptic seizures". Although most doctors saw new cases each year, two-thirds described their own service as poorly equipped to manage NES. Anti-epileptic drugs (AEDs) were commonly still being taken by children without epilepsy 6 months after their diagnosis. Preferred treatment approaches included supportive case management and cognitive behavioural therapy. Joint working with paediatrics and liaison with schools were seen as important. CONCLUSION: Despite many clinicians having experience of the disorder, NES seemed to occupy a neglected status, often falling between paediatrics and child mental health, with inadequately defined care pathways leading to sub-optimal treatment. Re configuration of services to prioritise liaison with paediatrics and education may support development of effective treatment, thus maximising health, social and educational opportunities for young people and their families. PMID- 29172139 TI - Clinical experience with eslicarbazepine acetate in adults with sub-analysis of elderly. AB - PURPOSE: Eslicarbazepine acetate (ESL) is indicated for treatment of focal epilepsy. Our aim was to evaluate the effect and tolerability of ESL in elderly and younger adults. The primary objective was to measure changes in seizure frequency before and after at least six months of treatment. Secondary objective was to analyse the safety profile. Sub-analysis was performed in patients previously treated with oxcarbamazepine. METHOD: A single-centre, retrospective study of patients with focal epilepsy treated with ESL. Data were collected by reviewing the clinical and laboratory files. Seventy-two patients received ESL, of which 14 were >=60 years old, and were analysed for adverse effects. Fifty nine patients received treatment for >=6 months and were included in the evaluation of seizure frequency; in this group 12 were >=60 years old. RESULTS: Seizure frequency (n=59) was reduced for both young adults (< 60years) and elderly adults (>=60); both groups achieved better seizure control from an average of 2 to 0.5 (p-value: 0.002) and 3.5 to 0.65 (p-value:<0.05) seizures per month, respectively. Adverse effects leading to treatment discontinuation (n=72) were more frequent in elderly (42.9%) than in young adults (17.2%) (p-value 0.04). There was no significant difference in mild adverse effects between young (15.5%) and elderly adults (14.3%). Most common adverse effects were somnolence, gastrointestinal disturbances and dizziness. CONCLUSIONS: The study indicates that ESL has an advantageous profile in relation to seizure control. The discontinuation rate might be higher in elderly than in younger adults. Further prospective studies are needed to confirm these conclusions. PMID- 29172140 TI - A novel electrochemical aptasensor for highly sensitive and quantitative detection of the streptomycin antibiotic. AB - In the present study, we report a facile approach to employ gold nanoparticle (AuNPs) and thiol graphene quantum dots (GQD-SH) as the nanomaterial for ultrasensitive detection of streptomycin (STR). Based on this strategy, a GQD-SH was immobilized onto the surface of a glassy carbon electrode (GCE). AuNPs have been immobilized on SH groups of GQDs through bonding formation of AuS and Apt have been loaded on the electrode surface through the interaction between thiol group of aptamer. By incubating STR as a target onto the surface of the prepared Apt/AuNPs/GQD-SH/GCE as a proposed nanoaptasensor, the Apt/STR complex was formed and the changes of the electrochemical signal were evaluated with the EIS technique. The proposed nanoaptasensor showed wide linear range from 0.1 to 700pgml-1. Finally, the proposed nanoaptasensor was successfully applied for the determination of STR in real samples and satisfactory results were obtained. PMID- 29172141 TI - New sensor based on membranes with magnetic nano-inclusions for early diagnosis in periodontal disease. AB - A series of sodium selective membranes with magnetic nano-inclusions using p tertbutyl calix[4]arene as ionophore and polymeric matrix (polyvinyl chloride) have been developed, and the corresponding sodium selective sensors were obtained for the first time. A linear range was registered between 3.1 * 10-5 and 10 1moldm-3 and near Nernstian electrochemical answer: 55.73mV/decade has been recoreded for PVC (polyvinyl chloride) - based sodium selective sensor, with a response time of 45s. Due to their small dimensions, sensors could be used for measuring ions from the gingival crevicular fluid directly into the peri-odontal pocket, avoiding the difficulties of collecting an appropriate amount of fluid for analysis. Alterations in the inorganic ions level could be evidenced with this new device, assisting the early diagnosis and prevention of periodontal disease. PMID- 29172142 TI - Detection of early stage prostate cancer by using a simple carbon nanotube@paper biosensor. AB - This study is an investigation for an inexpensive, simple and sensitive biosensor to detect prostate cancer using bioactivated-multi wall carbon nanotubes (MWCNTs, diameter of 20nm, length of 5um) and a micro-pore filter paper (pore size of 0.45um). For the immunoassay of prostate specific antigen (PSA), which is a biomarker of prostate cancer, MWCNTs were activated with PSA antibody (monoclonal antibody of the prostate specific antigen) by using N-(3-dimethylaminopropyl)-N' ethylcarbodiimide hydrochloride (EDC) and N-hydroxysulfosuccinimide sodium salt (NHSS). The activated MWCNTs were deposited on the micro-pore filter paper to use as a biosensor. The prepared biosensor can assay from 0 to 500ng/mL of PSA level within 2h with the detection limit of 1.18ng/mL by the measurement of resistance change. The resistance change was caused by site selective interaction between PSA and PSA-antigen with an inexpensive bench top digital multimeter (5 1/2 digits). The detection range and sensitivity of the prepared sensor are good enough to diagnose the early stage of prostate cancer (> 4ng/mL of PSA). This paper-based biosensor is about 20 times cheaper (fabricated biosensor price: 2.4 $) and over 10 times faster than enzyme-linked immunosorbent assay (ELISA), which is a general method for the detection of a specific protein in the modernized hospitals. Furthermore, the maximum detection limit is about 50 times higher than ELISA.

AB - A novel bi-component composite of porous self-assembled micro-/nanostructured Ni0.1Mn0.9O1.45 microellipsoids as high-performance anode electrocatalyst for microbial fuel cells (MFCs) is successfully synthesized via a simple coprecipitation reaction in microemulsion and calcination method in air atmosphere. The morphology and structural characterization indicate that the as fabricated Ni0.1Mn0.9O1.45 product is consist of Mn2O3 and NiMn2O4 (n(Mn2O3): n(NiMn2O4) = 0.35: 0.1) and has a porous microellipsoidal morphology. The microellipsoids are compose of numerous layered micro-/nanostructured blocks and the special porous microellipsoids structure of Ni0.1Mn0.9O1.45 offers a large specific surface area for bacteria adhesion. The porous Ni0.1Mn0.9O1.45 microellipsoids as anode electrocatalyst for MFCs exhibits excellent electrocatalytic activity to promote the extracellular electron transfer (EET) between the anode and bacteria, hence improves the performance of MFC. The MFC equipped with Ni0.1Mn0.9O1.45/CF anode achieves a maximum power density of 1.39 +/- 0.02Wm-2, is significantly higher than that of commercial carbon felt anode. This work proposes a new method for the synthesis of high-performance and environmentally friendly anode electrocatalyst for MFCs. PMID- 29172144 TI - A molecularly imprinted electrochemiluminescence sensor based on upconversion nanoparticles enhanced by electrodeposited rGO for selective and ultrasensitive detection of clenbuterol. AB - A simple, efficient and sensitive molecularly imprinted electrochemiluminescence sensor (MIECLS) based on reduced graphene oxide (rGO) and upconversion nanoparticles (UCNPs) was developed for determination of clenbuterol (CLB). In this study, rGO generated by electrodeposition of graphene oxide not only acted as carrier for immobilizing UCNPs, but also had a significant impact in boosting electrochemiluminescence (ECL) response of UCNPs thanks to its high conductivity, superior electron transport rate and large specific surface area. UCNPs as an advanced ECL emitter possessed wonderful ECL performance. Furthermore, the introduction of molecularly imprinted polymers (MIP) endowed the ECL sensor a new character of specifically identifying analyte CLB. Under the optimal experimental conditions, the ECL signal was proportional to the logarithm of CLB concentration in the range of 10nM to 100uM with a low detection limit of 6.3nM. The proposed MIECLS combining the advantages of UCNPs-ECL and MIP exhibited good sensitivity, desirable selectivity and favorable stability, indicating enormous potential in the future of food safety detection. PMID- 29172145 TI - A novel 3D bioprinted flexible and biocompatible hydrogel bioelectronic platform. AB - Bioelectronics platforms are gaining widespread attention as they provide a template to study the interactions between biological species and electronics. Decoding the effect of the electrical signals on the cells and tissues holds the promise for treating the malignant tissue growth, regenerating organs and engineering new-age medical devices. This work is a step forward in this direction, where bio- and electronic materials co-exist on one platform without any need for post processing. We fabricate a freestanding and flexible hydrogel based platform using 3D bioprinting. The fabrication process is simple, easy and provides a flexible route to print materials with preferred shapes, size and spatial orientation. Through the design of interdigitated electrodes and heating coil, the platform can be tailored to print various circuits for different functionalities. The biocompatibility of the printed platform is tested using C2C12 murine myoblasts cell line. Furthermore, normal human dermal fibroblasts (primary cells) are also seeded on the platform to ascertain the compatibility. PMID- 29172147 TI - Interpreting solution X-ray scattering data using molecular simulations. AB - Small-angle and wide-angle X-ray scattering in solution (SAXS, WAXS, SWAXS) is an increasingly accurate method for obtaining information on biomolecular structures, ensembles, and time-resolved dynamics at near-native conditions. However, the interpretation of the solution scattering data by computational methods is complicated by the low information content of the data, by scattering contributions from the hydration layer, and by unknown systematic errors. In the light of available computational methods, we first review the main computational challenges with the interpretation of SWAXS data. Molecular dynamics (MD) simulations may help to overcome these challenges and guide the interpretation of SWAXS in multiple ways. The physical information in atomistic force fields complements the low-information SWAXS data; explicit-solvent MD may be used to predict solvent scattering, and the MD-related sampling methods may guide the structure refinement against SWAXS data. PMID- 29172146 TI - Development, validation and application of a micro-liquid chromatography-tandem mass spectrometry based method for simultaneous quantification of selected protein biomarkers of endothelial dysfunction in murine plasma. AB - The objective of this study was to develop and validate the method based on micro liquid chromatography-tandem mass spectrometry (microLC/MS-MRM) for simultaneous determination of adiponectin (ADN), von Willebrand factor (vWF), soluble form of vascular cell adhesion molecule 1 (sVCAM-1), soluble form of intercellular adhesion molecule 1 (sICAM-1) and syndecan-1 (SDC-1) in mouse plasma. The calibration range was established from 2.5pmol/mL to 5000pmol/mL for ADN; 5pmol/mL to 5000pmol/mL for vWF; 0.375pmol/mL to 250pmol/mL for sVCAM-1 and sICAM 1; and 0.25pmol/mL to 250pmol/mL for SDC-1. The method was applied to measure the plasma concentration of selected proteins in mice fed high-fat diet (HFD), and revealed the pro-thrombotic status by increased concentration of vWF (1.31+/-0.17 nmol/mL (Control) vs 1.98+/-0.09 nmol/mL (HFD), p <0.05) and the dysregulation of adipose tissue metabolism by decreased concentration of ADN (0.62+/-0.08 nmol/mL (Control) vs 0.37+/-0.06 nmol/mL (HFD), p <0.05). In conclusion, the microLC/MS MRM-based method allows for reliable measurements of selected protein biomarkers of endothelial dysfunction in mouse plasma. PMID- 29172148 TI - Genetic characterization, micropropagation, and potential use for arsenic phytoremediation of Dittrichia viscosa (L.) Greuter. AB - In the last decade, many scientists have focused their attention on the search for new plant species that can offer improved capacities to reclaim polluted soils and waters via phytoremediation. In this study, seed batches from three natural populations of Dittrichia viscosa, harvested in rural, urban, and industrial areas of central and southern Italy, were used to: (i) evaluate the genetic and morphological diversity of the populations; (ii) develop an efficient protocol for in-vitro propagation from seedling microcuttings; (iii) achieve optimal acclimatization of micropropagated plants to greenhouse conditions; (iv) test the response to arsenic (As) soil contamination of micropropagated plants. The genetic biodiversity study, based on Random Amplification of Polymorphic DNA (RAPD), as well as the morphometric analysis of 20 seedlings from each population revealed some degree of differentiation among populations. Based on these data, the most biodiverse plants from the three populations (10 lines each) were clonally multiplied by micropropagation using microcuttings of in-vitro grown seedlings. Three culture media were tested and Mureshige and Skoog medium was chosen for both seedling growth and micropropagation. The micropropagated plants responded well to greenhouse conditions and over 95% survived the acclimatization phase. Four clones were tested for their capacity to grow on soil spiked with NaAsO2 and to absorb and accumulate the metalloid. All clones tolerated up to 1.0mg As. At the end of the trial (five weeks), As was detectable only in leaves of As-treated plants and concentration varied significantly among clones. The amount of As present in plants (leaves) corresponded to ca. 0.10-1.7% of the amount supplied. However, As was no longer detectable in soil suggesting that the metalloid was taken up, translocated and probably phytovolatilized.

AB - Deltamethrin (DTM) is a synthetic pyrethroid insecticide highly used by farmers and home users. This pesticide has lipophilic properties that facilitate a high absorption and can cause toxicity in non-target organisms. During foraging, the fruit-eating bats Artibeus lituratus are exposed to pesticides. However, the knowledge of the toxicity of pesticides on the physiology of bats is relatively scarce. This study aimed to check the toxicity of short-term exposure to low concentration of DTM on fruit-eating bat A. lituratus. After seven days of exposure to two doses of DTM (0.02 and 0.04mg/kg of papaya), the fruit bats showed an increase in the enzyme aspartate aminotransferase, alanine aminotransferase, and hyperglycemia. The liver and pectoral muscle presented oxidative stress. In the liver, the hydrogen peroxide (H2O2) and nitric oxide (NO) were increased as well as the antioxidant glutathione (GSH), the activity of glutathione S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) but in a lesser extent. Yet, total lipids were increased while hepatic glycogen content is reduced. The pectoral muscle showed NO, SOD, CAT, malondialdehyde (MDA), and carbonyl increased protein levels in both concentrations of DTM. All these results show that low doses of DTM can cause hepatic and muscular toxicity and induce changes in carbohydrate metabolism. Physiological changes caused by exposure to DTM in bats may have direct consequences in flight capacity, reproduction, and metabolism of these animals.

AB - The increasing presence of pharmaceuticals in aquatic environments in the last decades, derived from human and veterinary use, has become an important environmental problem. Previous studies have shown that ibuprofen (IB) and carbamazepine (CBZ) modify physiological and biochemical processes in Senegalese sole (Solea senegalensis) in a temperature-dependent manner. In other vertebrates, there is evidence that both of these pharmaceuticals interfere with the 'arachidonic acid (AA) cascade', which is responsible for the biosynthesis of numerous enzymes that are involved in the osmoregulatory process. The present work aims to study the temperature-dependent effects of these two pharmaceuticals on several biochemical and molecular parameters in Senegalese sole. Regarding osmoregulation, Na+, K+ -ATPase enzyme activity was determined in the gills, kidney and intestine, and the expressions of both Na+, K+ -ATPase 1alpha-subunit isoforms (ATP1A1a and ATP1A1b) were quantified in gills. Gill prostaglandin endoperoxide synthase-2 (PTGS2) gene expression and fatty acid composition were selected to determine the interference of both pharmaceuticals with the AA cascade. Senegalese sole juveniles, acclimatised at 15 degrees C or 20 degrees C, were exposed through intraperitoneal injection to IB (10mg/kg) and CBZ (1mg/kg) for 48h. Non-injected fish (Control) and those injected with the carrier (sunflower oil; S.O.), acclimated at each of the two temperatures, were used for comparison. The results show that IB directly affected the osmoregulatory mechanisms that alter gill and intestine Na+, K+ -ATPase activities. In addition, the copy number of ATP1A1a was higher at 20 degrees C than at 15 degrees C, which could be a direct response to the temperature variation. The gene expression of PTGS2 was affected by neither drug administration nor acclimation temperature. Nevertheless, detailed analysis of AA and eicosapentaenoic acid (EPA) percentages revealed a CBZ-derived effect in the fatty acid composition of the gills.

AB - Lung failure is responsible for significant morbidity and is a frequent cause of death in ataxia-telangiectasia (A-T). Disturbance in the redox balance of alveolar epithelial cells must be considered as a causal factor for respiratory disease in A-T. To investigate bronchoalveolar sensitivity to reactive oxygen species (ROS) and ROS-induced DNA damage, we used bleomycin (BLM) to induce experimental inflammation and fibrotic changes in the Atm-deficient mouse model. BLM or saline was administered by oropharyngeal instillation into the lung of Atm deficient mice and wild-type mice. Mice underwent pulmonary function testing at days 0, 9, and 28, and bronchoalveolar lavage (BAL) was analysed for cell distribution and cytokines. Lung tissue was analysed by histochemistry. BLM administration resulted in a tremendous increase in lung inflammation and fibrotic changes in the lung tissue of Atm-deficient mice and was accompanied by irreversible deterioration of lung function. ATM (ataxia telangiectasia mutated) deficiency resulted in reduced cell viability, a delay in the resolution of gammaH2AX expression and a significant increase in intracellular ROS in pulmonary epithelial cells after BLM treatment. This was confirmed in the human epithelial cell line A549 treated with the ATM-kinase inhibitor KU55933. Our results demonstrate high bronchoalveolar sensitivity to ROS and ROS-induced DNA damage in the Atm-deficient mouse model and support the hypothesis that ATM plays a pivotal role in the control of oxidative stress-driven lung inflammation and fibrosis. PMID- 29172152 TI - Safety and immune regulatory properties of canine induced pluripotent stem cell derived mesenchymal stem cells. AB - Mesenchymal stem cells (MSCs) exhibit broad immune modulatory activity in vivo and can suppress T cell proliferation and dendritic cell activation in vitro. Currently, most MSC for clinical usage are derived from younger donors, due to ease of procurement and to the superior immune modulatory activity. However, the use of MSC from multiple unrelated donors makes it difficult to standardize study results and compare outcomes between different clinical trials. One solution is the use of MSC derived from induced pluripotent stem cells (iPSC); as iPSC derived MSC have nearly unlimited proliferative potential and exhibit in vitro phenotypic stability. Given the value of dogs as a spontaneous disease model for pre-clinical evaluation of stem cell therapeutics, we investigated the functional properties of canine iPSC-derived MSC (iMSC), including immune modulatory properties and potential for teratoma formation. We found that canine iMSC downregulated expression of pluripotency genes and appeared morphologically similar to conventional MSC. Importantly, iMSC retained a stable phenotype after multiple passages, did not form teratomas in immune deficient mice, and did not induce tumor formation in dogs following systemic injection. We concluded therefore that iMSC were phenotypically stable, immunologically potent, safe with respect to tumor formation, and represented an important new source of cells for therapeutic modulation of inflammatory disorders. PMID- 29172154 TI - Specific binding of human C-reactive protein towards supported monolayers of binary and engineered phospholipids. AB - Circulating C-reactive protein (CRP) recognizes altered plasma membranes and activates complements systems in the acute phase of inflammation and infection in human. We have shown previously the calcium-independent adsorption of CRP toward 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) and lysophosphatidylcholine (LPC) on supported phospholipid monolayers. Here, we extended our study to other phospholipids and additives to elucidate the pattern recognition of CRP using a surface plasmon resonance biosensor. Surface density and lateral fluidity depended on the type of phospholipids in the monolayers as characterized by SPR and fluorescence recovery after photobleaching measurements. CRP recognized 1-palmitoyl-2-oleoyl-sn-glycero-3-phospho-l-serine (POPS) and 1 palmitoyl-2-oleoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (POPG) in the supported POPC monolayers without calcium at pH 7.4 and 5.5. As opposed to LPC, CRP did not recognize 3-sn-lysophosphatidylethanolamine in the POPC monolayers in calcium free conditions. While, the addition of 1-palmitoyl-2-oleoyl-sn-glycero-3 phosphoethanolamine (POPE) or sphingomyelin to supported POPC monolayers blocked CRP adsorption. Calcium-dependent CRP binding was observed only at pH 5.5 on supported monolayers of engineered phospholipids with inverted headgroups relative to POPC. The complement 1q (C1q) protein recognized the active form of CRP on the supported phospholipid monolayers. The discovery of CRP recognition with these phospholipids aids our understanding of the activation dynamics of CRP with phospholipid-based biomaterials when used during the acute phase. PMID- 29172153 TI - Ajmaline blocks INa and IKr without eliciting differences between Brugada syndrome patient and control human pluripotent stem cell-derived cardiac clusters. AB - The class Ia anti-arrhythmic drug ajmaline is used clinically to unmask latent type I ECG in Brugada syndrome (BrS) patients, although its mode of action is poorly characterised. Our aims were to identify ajmaline's mode of action in human induced pluripotent stem cell (hiPSC)-derived cardiomyocytes (CMs), and establish a simple BrS hiPSC platform to test whether differences in ajmaline response could be determined between BrS patients and controls. Control hiPSCs were differentiated into spontaneously contracting cardiac clusters. It was found using multi electrode array (MEA) that ajmaline treatment significantly lengthened cluster activation-recovery interval. Patch clamping of single CMs isolated from clusters revealed that ajmaline can block both INa and IKr. Following generation of hiPSC lines from BrS patients (absent of pathogenic SCN5A sodium channel mutations), analysis of hiPSC-CMs from patients and controls revealed that differentiation and action potential parameters were similar. Comparison of cardiac clusters by MEA showed that ajmaline lengthened activation recovery interval consistently across all lines. We conclude that ajmaline can block both depolarisation and repolarisation of hiPSC-CMs at the cellular level, but that a more refined integrated tissue model may be necessary to elicit differences in its effect between BrS patients and controls. PMID- 29172155 TI - Controlling insulin release from reverse hexagonal (HII) liquid crystalline mesophase by enzymatic lipolysis. AB - In the present study we aimed to control insulin release from the reverse hexagonal (HII) mesophase using Thermomyces lanuginosa lipase (TLL) in the environment (outer TLL) or within the HII cylinders (inner TLL). Two insulin loaded systems differing by the presence (or absence) of phosphatidylcholine (PC) were examined. In general, incorporation of PC into the HII interface (without TLL) increased insulin release, as a more cooperative system was formed. Addition of TLL to the systems' environments resulted in lipolysis of the HII structure. In the absence of PC, the lipolysis was more dominant and led to a significant increase in insulin release (50% after 8h). However, the presence of PC stabilized the interface, hindering the lipolysis, and therefore no impact on the release profile was detected during the first 8h. Entrapment of TLL within the HII cylinders (with and without PC) drastically increased insulin release in both systems up to 100%. In the presence of PC insulin released faster and the structure was more stable. Consequently, the presence of lipases (inner or outer) both enhanced the destruction of the carrier, and provided sustained release of the entrapped insulin. PMID- 29172156 TI - Comparative investigation of X-ray contrast medium degradation by UV/chlorine and UV/H2O2. AB - The degradation of iopamidol and diatrizoate sodium (DTZ) by UV/chlorine was carried out according to efficiency, mechanism, and oxidation products, and compared to that by UV/H2O2. The pseudo-first order rate (k') of iopamidol and DTZ was accelerated by UV/chlorine compared to that by UV and chlorine alone. k' of iopamidol and DTZ by UV/chlorine increased with increasing chlorine dosage. Both of iopamidol and DTZ could not be effectively removed by UV/H2O2 compared to that by UV/chlorine. Secondary radicals (Cl2- and ClO) rather than primary radicals (HO and Cl) were demonstrated to be mainly responsible for the enhanced removal of iopamidol and DTZ by UV/chlorine. The oxidation products of iopamidol and DTZ resulting from UV/chlorine and UV/H2O2 process were identified, and differences existed in the two systems. IO3- (the desired sink of I-) was the major inorganic product in the UV/chlorine process whereas I- was the predominant inorganic product in the UV/H2O2 process. The formation of chlorine-containing products during the degradation of iopamidol and DTZ by UV/chlorine was also observed. H-abstraction, additions, de-iodination were shared during the degradation of iopamidol by UV/chlorine and UV/H2O2. Neutral pH condition was preferred for the removal of iopamidol and DTZ by UV/chlorine. UV/chlorine could also be applied in real waters for the removal of iopamidol and DTZ. PMID- 29172157 TI - New particle formation and growth at a suburban site and a background site in Hong Kong. AB - Atmospheric nanoparticles have great impacts on human health and global climate change. The number concentrations and size distributions of nanoparticles in the size range of 5.5-350.4 nm were detected at a background site and a suburban site in Hong Kong from summer to winter in 2011 and in autumn of 2013, respectively. Significantly higher particle number concentrations in all modes were observed at the suburban site (p < 0.05) during the sampling periods, possibly due to stronger primary emissions/regional transport and more intensive new particle formation (NPF). Particle number concentrations were much enhanced under northerly winds at both sites, resulting from regional transport of Aitken and accumulation mode particles, enhanced local NPF and occasionally low condensation sink. NPF was mainly limited by the precursors of condensable vapors and oxidative capacity of the atmosphere at the background site and the suburban site, respectively. In most cases, the formation rate of 5.5 nm particles was a function of sulfuric acid vapor to the power of 1.32 +/- 0.34 at the background site and 0.81 +/- 0.31 at the suburban site, abiding by the cluster activation theory. However, ozonolysis of monoterpenes (particularly alpha-pinene) might also drive NPF, particularly in the afternoon. These reactions also contributed to the growth of nucleation mode particles, which was largely explained by sulfuric acid vapor (73.6 +/- 10% at the background site and 60.4 +/- 9.8% at the suburban site). In contrast, the oxidations of isoprene, beta-pinene and aromatics (particularly xylenes and trimethylbenzenes) were found to participate in the growth of Aitken mode particles. PMID- 29172158 TI - Facing the rain after the phase out: Performance evaluation of alternative fluorinated and non-fluorinated durable water repellents for outdoor fabrics. AB - Fluorinated durable water repellent (DWR) agents are used to obtain water and stain repellent textiles. Due to the on-going phase-out of DWRs based on side chain fluorinated polymers (SFP) with "long" perfluoroalkyl chains, the textile industry lacks suitable alternatives with comparable material characteristics. The constant development and optimization of SFPs for textile applications initiated more than half a century ago has resulted in a robust and very efficient DWR-technology and textiles with exceptional hydro- and oleo-phobic properties. The industry is now in the predicament that the long-chain SFPs with the best technical performance have undesirable toxicological and environmental behaviour. This study provides a comprehensive overview of the technical performance of presently available fluorinated and non-fluorinated DWRs as part of a chemical alternatives assessment (CAA). The results are based on a study with synthetic outdoor fabrics treated with alternative DWRs and tested for repellency using industrial standard and complementary methods. Using this approach, the complex structure-property relationships of DWR-polymers could be explained on a molecular level. Both short-chain SFPs and non-fluorinated DWRs showed excellent water repellency and durability in some cases while short-chain SFPs were the more robust of the alternatives to long-chain SFPs. A strong decline in oil repellency and durability with perfluoroalkyl chain length was shown for SFP DWRs. Non-fluorinated alternatives were unable to repel oil, which might limit their potential for substitution in textile application that require repellency towards non-polar liquids. PMID- 29172159 TI - Electro-oxidation of Ofloxacin antibiotic by dimensionally stable Ti/RuO2 anode: Evaluation and mechanistic approach. AB - Present study investigates the potential of Ti/RuO2 electrode for degradation and mineralization of Ofloxacin (OFLX) antibiotic from synthetic wastewater by electro-oxidation (EO) method, not reported earlier. Effects of various EO parameters such as applied current (I), initial pH, initial OFLX concentration (C0) and supporting electrolyte concentration on %OFLX removal efficiency and %TOC removal efficiency were systematically studied and reported. Decay kinetics of OFLX by varying C0 and applied I were also studied. Additionally, mineralization current efficiency and specific energy consumption of OFLX mineralization were evaluated. Moreover, mode of oxidation method involved (direct and/or indirect oxidation) was also explored. Major OFLX transformation products during EO were identified using UPLC-Q-TOF-MS, and possible degradation reaction mechanism was proposed. Furthermore, operating cost analysis was performed to check the economic feasibility of the EO process. The optimum pH and current (I) were found to be ~6.8 (natural pH of OFLX wastewater) and 1 A, respectively. Mineralization current efficiency decreased from 7.8% to 4.9% with increase in I value from 0.25 to 1 A. ~80% of OFLX removal in 30 min of electrolysis and 46.3% TOC removal in 240 min of electrolysis at I = 1 A were observed. Pseudo-first-order kinetic model best fitted the experimental data showing R2 value ~ 0.99 for all the Co and applied I studied. PMID- 29172160 TI - The neurocognitive effects of a conducted electrical weapon compared to high intensity interval training and alcohol intoxication - implications for Miranda and consent. AB - While the physiologic effects of conducted electrical weapons (CEW) have been the subjects of numerous studies over nearly two decades, their effects on neurocognitive functioning, both short-term and long-term, have only recently been studied. In a 2014 study involving use-of-force scenarios, including a CEW scenario, we found that there was a decline in neurocognitive performance immediately post-scenario in all groups; however this effect was transient, of questionable clinical/legal significance, not statistically different between the groups, and, returned to baseline by one hour post-scenario. Two subsequent studies by other authors have also found transient neurocognitive effects in the immediate post-exposure period; however, in one study, the effect was greater in one measure (of 5) for the CEW compared to exertion, and the authors suggested that this effect could have implications for the Miranda waiver obtained before custodial interrogation as well as consent. In our current study, we compared the neurocognitive effects of an exposure to a CEW to another exertion regimen, as well as to alcohol intoxication given the latter has significant established case law with regard to the Miranda waiver and consent. Such a comparison may offer more insight into the clinical/legal significance of any measured changes. As with the prior studies, the neurocognitive performance decrements of the CEW and exertion regimens, found only in one measure in this study (of three), were transient, and here, non-significant. Only alcohol intoxication resulted in statistically significant performance declines across all measures and these were persistent over the study period. Given that the neurocognitive changes associated with the CEW were non-significant, but were significant for alcohol intoxication, and given that current case law does not use intoxication as a per se or bright line barrier to Miranda and consent, our results do not suggest that a CEW exposure should preclude waiving of Miranda rights or obtaining consent. PMID- 29172161 TI - Urban upbringing and childhood respiratory and allergic conditions: A multi country holistic study. AB - OBJECTIVE: We integratively assessed the effect of different indoor and outdoor environmental exposures early in life on respiratory and allergic health conditions among children from (sub-) urban areas. METHODS: This study included children participating in four ongoing European birth cohorts located in three different geographical regions: INMA (Spain), LISAplus (Germany), GINIplus (Germany) and BAMSE (Sweden). Wheezing, bronchitis, asthma and allergic rhinitis throughout childhood were assessed using parental-completed questionnaires. We designed "environmental scores" corresponding to different indoor, green- and grey-related exposures (main analysis, a-priori-approach). Cohort-specific associations between these environmental scores and the respiratory health outcomes were assessed using random-effects meta-analyses. In addition, a factor analysis was performed based on the same exposure information used to develop the environmental scores (confirmatory analysis, data-driven-approach). RESULTS: A higher early exposure to the indoor environmental score increased the risk for wheezing and bronchitis within the first year of life (combined adjusted odds ratio: 1.20 [95% confidence interval: 1.13-1.27] and 1.28 [1.18-1.39], respectively). In contrast, there was an inverse association with allergic rhinitis between 6 and 8 years (0.85 [0.79-0.92]). There were no statistically significant associations for the outdoor related environmental scores in relation to any of the health outcomes tested. The factor analysis conducted confirmed these trends. CONCLUSION: Although a higher exposure to indoor related exposure through occupants was associated with an increased risk for wheezing and bronchitis within the 1st year, it might serve as a preventive mechanism against later childhood allergic respiratory outcomes in urbanized environments through enhanced shared contact with microbial agents. PMID- 29172162 TI - Isolation and characterization of a respirable particle fraction from residential house-dust. AB - Indoor air pollution has caused increasing concern in recent years. As we spend most of our lives indoors, it is crucial to understand the health effects caused by indoor air pollution. Household dust serve as good proxy for accessing indoor air pollution, especially smaller dust particles that can pass into the lungs are of interest. In this study we present an efficient method for the isolation of dust particles in the respirable size range. The respirable fraction was recovered from vacuum cleaner bags, separated by stepwise sieving, followed by characterization for size, morphology, surface area, organic content and elemental composition. The respirable fraction was obtained in a yield of 0.6% with a specific surface area of 2.5m2/g and a Mass Median Aerodynamic Diameter of 3.73 +/- 0.15um. Aluminum and zink were the dominating metals measured in the dust, whereas the major mineral components were found to be silicon dioxide and calcium carbonate. The fraction of organic matter in the dust was measured to be 69 +/- 1%. The organic matrix contained bacterial and fungi and a presence of skin fragments. We present here an efficient and fast method for the isolation of dust particles in the respirable size range. That is of considerable value due to the need for large quantities of respirable particle fractions to conduct toxicological studies and risk assessment work. PMID- 29172164 TI - Electrolysis assisted persulfate with annular iron sheet as anode for the enhanced degradation of 2, 4-dinitrophenol in aqueous solution. AB - Annular iron sheet (AIS), playing a dual role of anode electrode and source of activator, was combined with electrolysis technology for the activation of persulfate to improve the degradation of 2, 4-dinitrophenol (DNP) in aqueous solution. In this study, effects of current density (0-10.0mA/cm2), persulfate (PS) dosage (0-8.0mM), initial pH (3.0-11.0), reaction temperature (25-60 degrees C) and reaction time (0-30min) on COD removal of DNP in aqueous solution were investigated, respectively. COD removal reached its maximal value (63.4%) after 15min treatment due to the synergistic effect in electro/AIS/PS system under the optimal conditions. Furthermore, comparative studies of 7 different experimental processes were setup. In addition, the reasonable DNP degradation pathway was proposed based on intermediates detected by HPLC. According to characterization analysis of SEM-EDS, XRD and XPS of the generated flocculation in electro/AIS/PS system, the possible reaction mechanism was proposed in detail. In a word, the electrolysis process coupled with annular iron sheet as anode activating persulfate technology shows a significant synergetic effect in enhancing degradation of DNP in aqueous solution. PMID- 29172165 TI - BS12-assisted flotation for the intensification of SNPs separation from CMP wastewater using a novel flotation column. AB - In view of the extremely small size, high stable dispersion and intricate colloidal nature of silica nanoparticles (SNPs) in chemical mechanical polishing (CMP) wastewater, they might not only have hazards for environment and human health, but also cause low separation efficiency by classical water-treatment processes. Thus, it would be an important challenge to develop an efficient flotation technology for the separation SNPs. For this propose, this paper firstly presented the interaction between SNPs and dodecyl dimethyl betaine (ambient-friendly surfactant). Secondly, a novel flotation column was developed for strengthening interfacial adsorption by micro-bubbles and enhancing foam drainage by internal of regular-decagonal hollow frustum (RHF). One vital finding was that the mixture of micro-bubbles and macro-bubbles was conducive to improving the flotation performance. Under the suitable operating conditions, the enrichment ratio (E) and recovery percentage (R) of SNPs could reach 30.4+/-1.5 and 90.8+/-4.5%, respectively. The great E and R were obtained simultaneously, revealing a good participation of RHF in the flotation. Without a doubt, owing to the low chemical reagent addition and the high flotation performance, it was clear that our flotation has huge implications for the separation of nanoparticles from their wastewaters. PMID- 29172166 TI - Removal of volatile odorous organic compounds over NiAl mixed oxides at low temperature. AB - In this paper, a series of NiAl hydrotalcite-like compounds (HTLCs) were prepared by the urea-decomposition method. Removal of carbonyl sulfide (COS) and methyl mercaptan (CH4S) over the hydrotalcite-derived oxides (HTO) at low temperature was studied. The Ni3Al-HTO exhibited higher catalytic activities than Ni3Al mixed oxides prepared by physical mixing method (Ni3Al-PM) or impregnation/calcination method (Ni3Al-IC). Based on the characterization, it was found that desulfurization activities are closely tied to the surface acid-base properties of catalysts. CO2-TPD indicates that the basic characteristic of the Ni3Al-HTO is prominent. XPS results showed that there was a strong interaction between Ni and Al element on Ni3Al-HTO. The first principle calculation based on density function theory was applied with the aim to study the change of basic sites. The results showed that Ni3Al-HTO presents a half-metallic characteristic. Electron transfer from the Al and O atom to the Ni atom was observed, which is helpful for the transfer of electrons from the surface and improves the catalytic activity. Analysis of the DRIFT spectra suggests that sulfate species was formed by the action of surface basic sites, resulting in the formation of H2O on the surface.

AB - Frontotemporal dementia (FTD) is a highly heritable condition with multiple genetic causes. In this study, similarities and differences of gray matter (GM) atrophy patterns were assessed among 3 common forms of genetic FTD (mutations in C9orf72, GRN, and MAPT). Participants from the Genetic FTD Initiative (GENFI) cohort with a suitable volumetric T1 magnetic resonance imaging scan were included (319): 144 nonmutation carriers, 128 presymptomatic mutation carriers, and 47 clinically affected mutation carriers. Cross-sectional differences in GM volume between noncarriers and carriers were analyzed using voxel-based morphometry. In the affected carriers, each genetic mutation group exhibited unique areas of atrophy but also a shared network involving the insula, orbitofrontal lobe, and anterior cingulate. Presymptomatic GM atrophy was observed particularly in the thalamus and cerebellum in the C9orf72 group, the anterior and medial temporal lobes in MAPT, and the posterior frontal and parietal lobes as well as striatum in GRN. Across all presymptomatic carriers, there were significant decreases in the anterior insula. These results suggest that although there are important differences in atrophy patterns for each group (which can be seen presymptomatically), there are also similarities (a fronto insula-anterior cingulate network) that help explain the clinical commonalities of the disease.

AB - Two-dimensional metal carbides and nitrides (MXenes) have attracted increasing attention for application in water/wastewater treatment. The functionalization of MXenes to increase their stability while demonstrating high pollutant removal can facilitate sustainable water/wastewater treatment processes. In this study, the highly stable magnetic titanium carbide (Ti3C2Tx) MXene nanocomposite (MGMX nanocomposite) was successfully synthesized through a facile hydrothermal approach and was tested for aqueous-phase adsorptive removal of mercuric ions. The synthesized MGMX nanocomposite was studied using characteristic analyses, showing high stability as revealed by zeta-potential analysis and dynamic light scattering technique. The MGMX nanocomposite presented excellent Hg(II) removal in a wide range of pH conditions, and an exceptional maximum experimental Hg(II) uptake capacity of 1128.41mgg-1 was observed. The adsorption behavior was investigated using the Redlich-Peterson adsorption isotherm, pseudo second-order kinetics, and thermodynamics models. In the adsorption/desorption investigation, the MGMX nanocomposite was reusable for up to five cycles of adsorption/desorption. The stability, hydrophilic nature, available adsorptive surfaces, and easy separation after reaction make the MGMX nanocomposite an efficient sorbent for the removal of toxic Hg(II) for water purification. PMID- 29172168 TI - Electrospun AOPAN/RC blend nanofiber membrane for efficient removal of heavy metal ions from water. AB - In this study, an innovative nano-material was prepared, which was ultilized to removal of heavy metal ions from wastewater. Polyacrylonitrile/cellulose acetate (PAN/CA) composite nanofibrous membranes were generated by the electronspinning technique first, and then amidoxime ployarcylonitrile/regenerate cellulose (AOPAN/RC) composite nanofibrous membranes were prepared by combining hydrolysis and amidoximation modification. The modification of composite nanofibers (AOPAN/RC) were consequently used in heavy metal ions adsorption. The characterizations of various different nanofibers were analyzed using scanning electron microscopy, Fourier transform infrared spectroscopy, surface area and pore size distribution analyzer and energy dispersive X-ray spectroscopy. Meantime, the adsorption equilibrium studies were studied. In addition, the saturation adsorption amount of nanofibrous membranes (at 25 degrees C) for Fe(III), Cu(II) and Cd(II) of 7.47, 4.26 and 1.13mmolg-1, respectively. The effects of pH value of solution, adsorption time and ions concentration on adsorption capacity were also investigated. Furthermore, the composite nanofibrous membranes after five times consecutive adsorption and desorption tests, the desorption rate of the Fe(III), Cu(II) and Cd(II) mental ions maintained more than 80% of their first desorption rate, AOPAN/RC composite nanofibrous reflected excellent resuability. PMID- 29172169 TI - Magnetic multi-metal co-doped magnesium ferrite nanoparticles: An efficient visible light-assisted heterogeneous Fenton-like catalyst synthesized from saprolite laterite ore. AB - Magnetic nanoparticles of multi-metal co-doped magnesium ferrite (MgFe2O4) were synthesized from saprolite laterite ore by a hydrothermal method, and firstly proposed as a heterogeneous photon-Fenton-like catalyst for degradation of Rhodamine B (RhB). The factors that influence the degradation reaction including pH value, the concentration of H2O2 and the amount of catalyst, were systematically investigated. The doped MgFe2O4 exhibited a degradation efficiency up to 96.8%, and the chemical oxygen demand (COD) and total organic carbon (TOC) removal efficiencies about 85.6% and 68.3%, respectively, under visible light illumination for 180min. The high activity is mainly attributed to the high specific surface area of the catalyst and the synergistic interaction between photo-catalytic oxidation and Fenton-like oxidation. Moreover, the catalyst also showed good stability and recycling performance for degrading RhB. After five consecutive degradation cycles, the activity decayed no more than 10%. Compared to other catalysts prepared from pure chemical agents, the multi-metal co-doped MgFe2O4 is more competitive due to its high activity, good stability, ease of recollection, and especially the use of saprolite laterite ore as precursor.

AB - Motivated by the persisting need for enhanced resolution in solution state NMR spectra, pure shift techniques such as Zangger-Sterk decoupling have recently attracted widespread interest. These techniques for homonuclear decoupling offer enhanced resolution in one- and multidimensional proton detected experiments by simplifying multiplet structures. In this work, a modification to the popular Zangger-Sterk technique PEPSIE (Perfect Echo Pure Shift Improved Experiment) is presented, which decouples pairs of spins even if they share the same volume element. This in turn can drastically improve the sensitivity, as compared to classical Zangger-Sterk decoupling, as larger volume elements can be used to collect the detected signal. Most interestingly, even in the presence of moderate strong coupling, the PEPSIE experiment produces clean and widely artifact free spectra. In order to better understand this - to us initially - surprising behaviour we performed analyses using numerical simulations and derived an (approximate) analytical solution from density matrix formalism. We show that this experiment is particularly suitable to study samples with strong signal clustering, a situation which can render classic Zangger-Sterk decoupling inefficient. PMID- 29172171 TI - Trastuzumab for metastatic breast cancer: Real world outcomes from an Australian whole-of-population cohort (2001-2016). AB - PURPOSE: Outcomes for patients treated in clinical trials may not reflect the experience in routine clinical care. We aim to describe the real-world treatment patterns and overall survival (OS) for women receiving trastuzumab for metastatic breast cancer (MBC). METHODS: Retrospective, whole-of-population cohort study using demographic, dispensing, and medical services data for women in the Herceptin Program for HER2+MBC. We estimated time on trastuzumab and OS from first dispensing of trastuzumab for MBC and rates of cardiac monitoring prior to and during treatment. We stratified outcomes by two groups based on year of initiation: 2001-2008 and 2009-2015. We benchmarked outcomes to two key trastuzumab clinical trials: H0648g (median OS 25 months) and CLEOPATRA (control group median OS 41 months). RESULTS: Median age of the 5899 women at first trastuzumab dispensing was 57 years (interquartile range [IQR]: 48-66). Median time on trastuzumab increased from 15 months (7-33) in Group One to 18 months (8 42) in Group Two. Median OS increased from 27 months (12-57) in Group One to 38 months (16-83) in Group Two. Rates of cardiac monitoring increased at baseline (52%-76%), and on-treatment (47%-67%), in Group One and Two, respectively. CONCLUSIONS: OS, duration of trastuzumab, and frequency of cardiac monitoring increased over the study period. Outcomes for trastuzumab in this heterogeneous real world population were reassuringly comparable to those from clinical trials, with the median OS > 3 years in Group Two and 25% of patients living 7 years or longer. PMID- 29172172 TI - Visualization of old bruises in children: Use of violet light to record long-term bruises. AB - When a child consultation center evaluates abused children, evidence of the abuse must be documented. Children who have suffered physical abuse often have bruises, which cannot be confirmed by visualization when the bruise has healed. In forensics, a method to confirm an old bruise by ultraviolet radiation is possible. However, long-term ultraviolet exposure can be harmful. In this study, we observed 15 bruises on healthy volunteer children using four kinds of light sources, including ultraviolet radiation, over time. The violet light source enabled observation of a bruise for a longer time than ultraviolet radiation. Although other studies have shown that violet light is superior for enhancing bruises, this is the first report to evaluate data concerning the ability to identify bruises over time in living children. These results might help to identify evidence of past violence suffered by children.

PMID- 29172174 TI - Deficit of supramodal executive control of attention in schizophrenia. AB - Although a deficit in executive control of attention is one of the hallmarks in schizophrenia that has significant impact on everyday functioning due to its relationship with thought processing, whether this deficit occurs across modalities, i.e., is supramodal, remains unclear. To investigate the supramodal mechanism in SZ, we examined cross-modal correlations between visual and auditory executive control of attention in a group of patients with schizophrenia (SZ, n = 55) compared to neurotypical controls (NC, n = 55). While the executive control effects were significantly correlated between the two modalities in the NC group, these effects were not correlated in the SZ group, with a significant group difference in the correlation. Further, the inconsistency and magnitude of the cross-modal executive control effects were significantly larger in the SZ group compared to the NC group. Together, these results suggest that there is a disruption of a common supramodal executive control mechanism in patients with schizophrenia, which may be related to the thought processing disorder characterizing the disorder. PMID- 29172176 TI - ATP-sensitive and maxi potassium channels regulate BRL 37344-induced tocolysis in buffaloes-an in vitro study. AB - Cellular coupling of beta3-adrenoceptors (beta3-ADR) to potassium channels in myometrium is largely unknown. In vitro study was undertaken to unravel the presence of beta3-adrenergic receptors (ADR) and the role of K+-channels in mediating beta3-ADR-induced relaxation in isolated myometrial strips from cyclic non-pregnant water buffaloes. Isometric tension was recorded in isolated myometrial strips using data acquisition system based physiograph. Compared to SR 59230A, BRL 37344 was found to be more potent in inducing beta3-dependent myometrial relaxation which was significantly (p < 0.05) inhibited in the presence of beta3 antagonist, SAR 150640. The immunoreactive protein to beta3-ADR was also detected in membrane fraction of myometrial protein. Further, incubation with BRL 37344 (10 MUM) significantly (p < 0.05) increased c-AMP accumulation (37.58 +/- 9.52 pmol/mg protein; n = 4) in the myometrial strips compared to basal c-AMP level (16.85 +/- 3.87 pmol/mg protein; n = 4). The concentration response curves (CRC) of BRL 37344 were significantly (p < 0.05) shifted towards right in the presence of KATP channels specific blocker, glibenclamide (10 MUM) and maxi K+-channels (BKCa) specific blocker, iberiotoxin (100 nM), with decrease in both efficacy and potency as compared to control. However, 4-aminopyridine (4 AP), a specific blocker of the voltage gated K+-channels (Kv), failed to alter the CRC of BRL 37344. Existence of immunoreactive protein to Kir6.1, alpha subunit of BKCa and Kv1.1 channels were also detected in the membrane fraction of myometrial protein. Based on the above findings, it can be concluded that BRL 37344 is a potent stimulator of beta3-adrenoceptors in buffalo myometrium and besides mediating their effect through rise in c-AMP, they are coupled to KATP and BKCa channels in inducing tocolytic effects. PMID- 29172175 TI - A predictive threshold value for the diagnosis of early pregnancy in cows using interferon-stimulated genes in granulocytes. AB - Interferon tau plays an important role in establishing bovine pregnancy. Interferon-stimulated genes (ISGs) have been examined to identify a suitable indicator for the diagnosis of early gestation in cows. Although ISGs can be specifically detected in peripheral white blood cells during early gestation, its reliability remains to be validated. In the current study, a predictive threshold level of ISGs to determine pregnancy in cows during Days 20-22 of gestation was verified by analyzing the expression of ISGs in granulocytes and peripheral blood leucocytes (a total of 57 cows were used, 28 of which were pregnant and 29 were non-pregnant). Four genes, interferon-stimulated gene 15 ubiquitin-like modifier (ISG15), MX dynamin like GTPase (MX) 1, MX2, and 2'-5'-oligoadenylate synthetase 1 (OAS1), were analyzed via quantitative RT-PCR and a receiver operating characteristic (ROC) curve was produced to visualize diagnostic accuracy measures. The expression values of the four ISGs during the estrous cycle (100 collection points from 65 cattle) were used to determine a pregnancy prediction cutoff value. Pregnancy status was determined using these cutoff values and then confirmed by ultrasonography. ROC analysis was then applied to confirm the accuracy of the pregnancy statuses (positive and negative) statistically. The statistical evaluation of the diagnostic accuracy measurements suggested that the average values of ISG15 and MX2 in granulocytes were reliable indicators of pregnancy within the three weeks after insemination with 80% accuracy. Average ISG15 and MX2 levels during the estrous cycle were more reliable biomarkers for the prediction of gestation. They predicted negative and positive pregnancies efficiently within three weeks after artificial insemination. PMID- 29172177 TI - Lupeol supplementation improves the developmental competence of bovine embryos in vitro. AB - Lupeol is a triterpene with various pharmacological properties. This study investigated the effect of lupeol on the in vitro development of bovine embryos. Oocytes (270 per group, 1620 in total) obtained from slaughterhouse-derived ovaries were matured and fertilized in vitro and then cultured for 8 days in a humidified atmosphere of 5% CO2 in air at 38.5 degrees C. The in vitro maturation medium was supplemented with 0.5, 1.0, 2.0, 3.0, and 4.0 MUM lupeol. Treatment with 2.0 MUM lupeol significantly (P < 0.05) improved blastocyst development. Hoechst 33342 staining and terminal deoxynucleotidyl transferase dUTP nick-end labeling showed that treatment with 2.0 MUM lupeol improved blastocyst quality by increasing the total cell number and reducing the apoptotic cell number. Confocal microscopy confirmed that treatment with 2.0 MUM lupeol significantly (P < 0.05) reduced the level of 8-oxoguanine, an indicator of reactive oxygen species. Lupeol treatment also significantly attenuated protein expression of nuclear factor-kappa B subunit 1 (NFKB1), cyclooxygenase (COX) 2, and CASP3. Real-time PCR analysis of nitric oxide synthase 2, NFKB1, COX2, CASP3, and BCL2-associated X protein supported the immunofluorescence data. In conclusion, lupeol is a potent antioxidant that improves bovine embryo development in vitro. PMID- 29172178 TI - A 10-year follow-up study of violent victimization in first episode psychosis: Risk and protective factors. AB - Violent victimization in persons with severe mental illness has long-term adverse consequences. Little is known about the long-term prevalence of victimization in first episode psychosis, or about factors affecting victimization throughout the course of illness. To assess the prevalence of violent victimization during a 10 year follow-up period in a group of first episode psychosis (FEP) patients, and to identify early predictors and risk factors for victimization. A prospective design was used with comprehensive assessments of violent victimization, treatment variables and functioning at baseline and during 10-year follow-up. A clinical epidemiological sample of FEP patients (n = 298) was studied. FEP patients in our study were at a 3.5 times greater risk of victimization as compared to the normal population. During the 10-year follow-up period, 23% of subjects fell victim to one or more violent assaults. Victimized patients were younger and reported less occupational activity. At 10-year follow-up, victimization was associated with more concomitant drug use, alcohol misuse and violent behavior, but not with a worse clinical or functional outcome. Treatment programs should focus on risk factors for victimization and develop behavioral alternatives to mitigate risk in FEP patients. PMID- 29172179 TI - Higher participation in physical activity is associated with less use of inpatient mental health services: A cross-sectional study. AB - There is a stark disparity in the physical health of people with mental illness compared to those without mental illness, resulting in shorter life expectancy and increased rates of preventable deaths. Physical activity has previously been shown to have a positive impact on various markers of mental health and has been linked with a reduction in hospital admissions for those with chronic physical illness. The purpose of this study was to investigate whether there is a relationship between physical activity and the number of days spent admitted to acute inpatient mental health wards in people with enduring mental illness. Eighty participants from four acute mental health wards in Oxfordshire, UK were included. Subjective and objective measurements of physical activity levels were collected alongside the amount of days spent admitted on acute mental health wards over the year previous. Participants who recorded higher levels of physical activity, both subjectively and objectively, were found to have spent less time admitted to acute mental health services. With a significant negative correlation found, future research should aim to investigate any causative link between physical activity and mental health admission. PMID- 29172180 TI - Microsatellite Alterations and Protein Expression of 5 Major Tumor Suppressor Genes in Gastric Adenocarcinomas. AB - PURPOSE: In gastric adenocarcinoma (GC), the major tumor suppressor genes (TSGs) such as p16, PTEN, Rb, E-cadherin, and p53, may play important roles in various regulatory pathways and in tumor suppression. This study evaluated the loss of heterozygosity (LOH) of microsatellite and protein expression of 5 TSGs and the results were examined for their correlation with clinicopathological factors. METHODS: LOH analysis was carried out using polymerase chain reactions with 15 polymorphic microsatellite markers of 5 chromosomes containing TSGs in 100 surgically resected tumors. Protein expression was evaluated by immunohistochemistry (IHC). RESULTS: LOH was detected in 83% of GCs. LOH of 9p21, 10q23, 13q14, 16q22, and 17p13 were detected in 26%, 31%, 24%, 22%, and 35% of cases, respectively. Protein expression of p16, PTEN, Rb, E-cadherin, and p53 were found to be 31%, 39%, 28%, 32%, and 46% of cases. Advanced GCs showed significantly higher rates of 17p13 LOH and p53 expression. 9p21 LOH and E cadherin IHC were correlated with higher tumor grade. Lymph node metastasis was correlated with the LOH of 9p21, 16q22, and 17p13 and IHC of the Rb and p53. A higher stage was correlated with 10q23 and 17p13 in LOH and p53 for IHC. CONCLUSION: These results suggest that LOH and protein expression of various TSGs are important in carcinogenesis and tumor invasion. Additionally, LOH and IHC may be useful clinical indicators for determining the prognosis of patients with GCs. In particular, the 17p13 LOH and p53 for IHC can be applied as simple evaluations in the clinic. PMID- 29172181 TI - Efficient removal of Cr(VI) from water by quaternized chitin/branched polyethylenimine biosorbent with hierarchical pore structure. AB - A novel chitin-based biosorbent (QCP) was synthesized by cross-linking quaternized chitin and branched polyethylenimine with the aid of epichlorohydrin for efficient removal of Cr(VI) from water. Because it possessed both quaternary ammonium groups and amino groups as well as the hierarchical pore structure, QCP presented a maximum adsorption capacity of 387.7 mg/g according to the Langmuir isotherm at 25 degrees C. The biosorption of QCP achieved the equilibrium within 40 min and followed the pseudo-second-order kinetic model. QCP worked well even in the solution with high pH and high content of competing anions and, it exhibited an excellent reusability. The main Cr(VI) uptake mechanism was confirmed to be electrostatic attractions between Cr(VI) anions and quaternary ammonium groups as well as the protonated amino groups, and followed by partial reduction of Cr(VI) to Cr(III) by amines and hydroxyls. This work may provide a potential for Cr(VI) removal by chitin-based biosorbents. PMID- 29172182 TI - Enhanced nitrogen and phosphorus removal from domestic wastewater via algae assisted sequencing batch biofilm reactor. AB - This study proposed a potential strategy for enhancement of nutrients removal from domestic wastewater by adding algae to sequencing batch biofilm reactor (SBBR) to form a novel algal-bacterial symbiosis (ABS) system. Results indicated that the algae-assisted SBBR increased the total nitrogen and phosphorus removal efficiencies from 38.5% to 65.8%, and from 31.9% to 89.3%, respectively. The carriers fixed at the top of the reactor were favorable for both formation of ABS system and algae enrichment. The chlorophyll-a increased to 3.59 mg/g at stable stage, which was 4.07 times higher than that in suspension. Moreover, the bio carrier replacement and sludge discharge were independent, indicating that the sludge and algae retention time could be separated. The mechanisms analysis suggested that the enhanced nitrogen and phosphorus mainly attributed to the enrichment of both algae biomass and total biomass in biofilm. This study highlights the significance of developing ABS system for wastewater treatment. PMID- 29172183 TI - Enzymatic hydrolysis at high dry matter content: The influence of the substrates' physical properties and of loading strategies on mixing and energetic consumption. AB - The present work investigates the impact of the physical properties and loading strategies of wheat straw and miscanthus on enzymatic hydrolysis at high DM concentration. Three parameters have been chosen to evaluate the enzymatic hydrolysis performance: (i) the mixing time, (ii) the energetic mixing consumption and (iii) the glucose concentration. It was demonstrated that the hydrolysis of miscanthus is easy to perform and has low viscosity. On the contrary, the higher porosity grade of wheat straw than miscanthus (73% against 52%) contributed to have a very high viscosity at 20% w/w DM. The development of a fed-batch strategy allowed the reduction of viscosity inducing the energetic consumption lowering from 30 kJ to 10 kJ. It has been also proven that the miscanthus addition in wheat straw achieved to decrease mixing energy consumption at 5-8 kJ, when it represented more than 30% of the total mass of the reaction medium. PMID- 29172184 TI - [Phenomenon of Perceived Duration in the Subjective Present]. AB - Among phenomena involving the subjective present, duration perception is especially worth discussing from the viewpoints of psychophysics, cognitive neuroscience, and computational modeling of underlying mechanisms. First, several situations in which moving visual stimuli appear to last longer are reported. Second, the phenomenon of illusory time compression, which occurs in a moving stimulus after prolonged observation of another stimulus moving at a faster speed, is described. Third, how an attended visual stimulus appears to last longer and how a stimulus appears to last for a shorter duration when attention is directed away are explained. Finally, possible underlying mechanisms in relation to the stages of hierarchical visual information processing are discussed. PMID- 29172185 TI - [Dynamic Attending Binds Time and Rhythm Perception]. AB - Relations between time and rhythm perception are discussed in this review of psychophysical research relevant to the multiple-look effect and dynamic attending theory. Discrimination of two neighboring intervals that are marked by three successive sounds is improved when the presentation of the first (standard, S) interval is repeated before that of the second (comparison, C), as SSSSC. This improvement in sensitivity, called the multiple-look effect, occurs because listeners (1) perceive regular rhythm during the repetition of the standard interval, (2) predict the timing of subsequent sounds, and (3) detect sounds that are deviated from the predicted timing. The dynamic-attending theory attributes such predictions to the entrainment of attentional rhythms. An endogenous attentional rhythm is synchronized with the periodic succession of sounds marking the repeated standard. The standard and the comparison are discriminated on the basis of whether the ending marker of the comparison appears at the peak of the entrained attentional rhythm. This theory is compatible with the findings of recent neurophysiological studies that relate temporal prediction to neural oscillations. PMID- 29172186 TI - [Neural Basis for Producing Temporal Order]. AB - It has been proposed that a position in time can be discriminated in two ways. First, each position is either past, present, or future (A series). Second, each position is either before or after another (B series). In this review, we aim to infer how the two series are represented in the brain on the basis of findings from clinical, neurophysiological, and neuroimaging studies. We suggest that the precuneus and posterior cingulate cortex are critically involved in the A series. In the B series, we suggest that a group of events are represented in space around the intraparietal cortex and are combined with the temporal directional cue provided by the motion signals in the left temporo-parietal junction. We also review a report that states that the B series is affected by alpha rhythm, the source of which is located in the precuneus. Taken together, we suggest that the precuneus and the regions adjacent to it play key roles in representing the A and B series. PMID- 29172187 TI - [Neural Mechanisms of Temporal Monitoring and Prediction]. AB - When waiting for a traffic light or dancing to a musical beat, we unconsciously keep track of elapsed time and precisely predict the timing of forthcoming sensory events. Temporal monitoring and prediction are integral to our daily life, and are regulated by neuronal processes through multiple global networks involving the frontoparietal cortices, the basal ganglia and the cerebellum. These processes are also known to be influenced by a variety of internal state and neuromodulators. Here, we review recent advance of research in the field. PMID- 29172188 TI - [Posterior Cingulate Cascading Delay Model for Timing Behavior]. AB - We present a novel model for timing behavior. This model is based on the firing property of neurons in the superficial layers of the posterior cingulate granular retrosplenial cortex (GRS) and does not require a unit-time clock. Suppose that event B occurs N seconds after event A and triggers behavior C. By our behavioral, physiological and anatomical experiments, we found the following facts. 1) Thalamic input carrying sensory information, A, is provided to the superficial layers of the GRS and delayed by the lateral cascading connection within the layers. 2) Hippocampal input (recall information, B) is provided to the deep layers of the GRS. 3) The GRS neurons show timing behavior that is dependent on the trial cycle. 4) Lesioning the GRS impaired the acquisition of trace fear memory and the production of fear-induced freezing behavior, C. Thus we would propose that neural circuits in the GRS play a crucial role in the animal behaviors requiring time discrimination. The question of whether Hebbian learning occurs at the convergent neurons that integrates thalamic and hippocampal information remains unanswered. PMID- 29172189 TI - [Representation of Time by Hippocampal Neurons]. AB - The hippocampus is involved in episodic memories of events including time and space. Many studies have focused on the neuronal processing mechanisms underlying spatial cognition and representation in the hippocampus; however, the time related aspects of memories have only recently become the focus of research. In this review, we first introduce recent reports demonstrating the importance of the hippocampus in the perception of time and then present the hippocampal neuronal dynamics for the representation of time, revealed by large-scale neuronal recording techniques. PMID- 29172190 TI - [Neural Mechanisms That Facilitate Adaptive Behavior Based on Acquired Stimulus Outcome Information]. AB - In response to changing internal and external situations, we always need to adapt our behavior based on previous experiences, particularly, acquired stimulus outcome information. The orbitofrontal cortex (OFC), a prefrontal cortical region, is critical for this type of decision-making. The current understanding of the fundamental functions of the OFC has been reviewed by introducing, as an example, how the OFC contributes to the processing of uncertain rewards. Furthermore, the importance of revealing context and temporally specific causal roles of neural circuits including the OFC in decision-making, as well as the techniques to achieve the goal, have been discussed.

AB - This study explores how time is conceptualized and linguistically encoded by human beings. In order to examine how the temporal systems develop in child language, we have conducted investigations on how their development relates to universal and idiosyncratic aspects of the temporal systems of the languages of the world. We have found that both the uniformity and the variation across languages in the development of tense-aspect marking in child language are attributable to the interaction of three aspects of the typological pattern of the target language: morphology, the presence or absence of optionality of tense aspect marking, and the inventory of tense-aspect markers. PMID- 29172192 TI - [Neuropsychology of the Psychological Present]. AB - The psychological present is a diverse psychological phenomenon, including the perception and evaluation of time, which has been studied from different perspectives. The experience of the psychological present is known to differ according to psychological state and cognitive processes, such as attention. Neuropsychological studies focused on brain-damaged patients have explored several aspects of the present, but few studies have examined the subjective aspect of the phenomenon. In this article, we focus on the subjective aspect of the present in brain-damaged patients and propose that the psychological present is maintained by several brain regions through the integration of multiple information sources. PMID- 29172193 TI - [Hypersensitivity as Extraordinary High Temporal Processing in Individuals with Autism-Spectrum Disorders]. AB - Most individuals with autism-spectrum disorders have hypersensitivity/hyposensitivity to various types of sensory stimuli. Although several hypotheses such as higher sensitivity to stimuli, alterations in brain structure and function, and dysfunction of inhibitory systems at the molecular level have been suggested, there is no convincing evidence. We found that individuals with high temporal resolution tended to have strong hypersensitivity to sensory stimuli and vice versa. In addition, we focused on a case with extraordinarily high temporal resolution across the tactile, auditory, and audio tactile domains. We believe that studying such an extreme case of temporal processing could facilitate an understanding of the neural basis of time perception. PMID- 29172194 TI - [Mental Space Navigation and Mental Time Travel]. AB - We examined patients with mental space navigation or mental time travel disorder to identify regions in the brain that may play a critical role in mental time travel in terms of clinical neuropsychology. These regions included the precneus, posterior cingulate gyrus, retrosplenial cortex, and hippocampus, as well as the orbitofrontal cortex: the anterior and posterior medial areas were both shown to be important in this process. Further studies are required to define whether these form a network for mental time travel. PMID- 29172195 TI - [Neural Mechanisms Underlying the Processing of Temporal Information in Episodic Memory and Its Disturbance]. AB - Episodic memory is defined as memory for personally experienced events, and includes memory content and contextual information of time and space. Previous neuroimaging and neuropsychological studies have demonstrated three possible roles of the temporal context in episodic memory. First, temporal information contributes to the arrangement of temporal order for sequential events in episodic memory, and this process is involved in the lateral prefrontal cortex. The second possible role of temporal information in episodic memory is the segregation between memories of multiple events, which are segregated by cues of different time information. The role of segregation is associated with the orbitofrontal regions including the orbitofrontal cortex and basal forebrain region. Third, temporal information in episodic memory plays an important role in the integration of multiple components into a coherent episodic memory, in which episodic components in the different modalities are combined by temporal information as an index. The role of integration is mediated by the medial temporal lobe including the hippocampus and parahippocampal gyrus. Thus, temporal information in episodic memory could be represented in multiple stages, which are involved in a network of the lateral prefrontal, orbitofrontal, and medial temporal lobe regions. PMID- 29172196 TI - [Memory of Past Events and Mental Time Travel in Apes]. AB - Mental time travel refers to the ability to recall a past event and imagine the future. Some researchers claim that this ability is unique to humans, while others argue that nonhuman animals also possess this ability. A study on apes by using eye-tracking revealed that chimpanzees and bonobos can remember a single event for 24 hours, suggesting that they possess at least some elements of mental time travel. PMID- 29172197 TI - [Voxel-Based Morphometry and Social Cognitive Function in Parkinson's Disease]. AB - In recent years, voxel-based morphometry (VBM) has been increasingly used to investigate local brain structures in Parkinson's disease (PD). Compared to healthy participants, PD patients tend to show reduced brain volume in limbic and paralimbic areas in early disease stages, while the neocortical areas, such as the temporal and frontal cortices, are affected in advanced patients. Moreover, there are many studies showing correlation between cognitive performance and local brain volume. In the last decade, emotional and social cognitive function, such as facial emotion recognition, emotional decision-making, and theory of mind, have been the target of VBM analysis in PD. These studies facilitate understanding of the nature of communication and behavioral disorders that some PD patients display. However, there are discrepancies in VBM results between studies. Future studies need to employ larger sample sizes and combined analysis of brain perfusion or network connectivity in order to confirm brain structural changes and their effects on social cognitive function in PD patients.

AB - The anti-MOG antibody is an autoantibody that induces inflammatory demyelinating lesions in the central nervous system in diseases such as optic neuritis, encephalitis, and myelitis. The recent development of a cell-based assay that can detect specific autoantibodies, which recognize conformational epitopes of membrane proteins, revealed the clinical features of diseases associated with the anti-MOG antibody. Because the disease spectrum of anti-MOG antibody-associated diseases is different from that of conventional demyelinating diseases, a new disease classification would be established in the near future. PMID- 29172199 TI - [Clinical Features of Very Elderly Patients Aged 90 Years or Above with Acute Ischemic Stroke: A Study by Using Diffusion Weighted Brain Magnetic Resonance Imaging]. AB - We investigated the diffusion weighted magnetic resonance imaging (DWI) features of 76 very elderly patients aged 90 years or above with acute ischemic stroke. Stroke subtypes were classified into five types according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) and the Japanese Stroke Databank. The incidence rates of atherothrombotic brain infarction (ATBI), atherothrombotic brain embolism (ATBE), lacunar infarction (LI), cardiogenic brain embolism (CBE) and undetermined type of brain infarction (UTBI) were 2.6%, 17.1%, 10.5%, 50.0% and 19.8%, respectively. We estimated that the incidence of acute ischemic stroke in women was 3.5-fold higher than that in men. This is likely because survival rate of females is higher than that of males in populations aged 90 years or above. The prevalence of atrial fibrillation (AF) was 46.1% in patients with brain infarctions, and 92.1% in patients with CBE. The frequency of multiple infarctions is 52.6% and that of single infarction is 47.4%. In DWI of lesions, the frequencies of territorial infarction in the cerebral hemisphere, borderzone infarction, and vertebrobasilar infarction were 85.5%, 13.2% and 17.1%, respectively. The frequencies of massive territorial infarction and cerebellar infarction were 23.7% and 13.2%, respectively. With regard to the relationship between DWI lesion topography and stroke subtypes, superficial infarctions in the cerebral hemisphere were seen in patients with ATBE, CBE and UTBI. Single infarctions deep in the cerebral hemisphere were seen in all patients with any of the five stroke subtypes. Massive territorial infarctions with infarctions in other sites of the cerebral hemisphere or vertebrobasilar region were seen only in patients with CBE, and single pontine infarction was seen only in patients with LI.

AB - OBJECT: Aneurysmal subarachnoid hemorrhage(SAH)associated with intracerebral hematoma(ICH)typically has a poor outcome. SAH with ICH tends to have a worse prognosis than SAH alone. The aim of the present study was to evaluate whether coil embolization during endovascular surgery with ventricle drainage and without ICH evacuation is an appropriate treatment. METHODS: A retrospective review was conducted between March 2012 and May 2015. Thirteen patients with SAH with ICH who underwent coil embolization were retrospectively analyzed. Modified Rankin Scale(mRS)scores were compared for postoperative clinical outcomes of different hematoma locations. RESULTS: All ruptured aneurysms in the present series of patients were treated using endovascular surgery. Six patients underwent additional ventricle drainage. Only one patient underwent craniotomy for evacuation of the hematoma following coil embolization. Despite ten out of thirteen patients(76.9%)having a preoperative SAH clinical grade, as evaluated using the World Federation of Neurosurgical Societies grading system of IV or V, six(46.2%)patients had a favorable outcome(mRS=0-2). CONCLUSIONS: Coil embolization for ruptured aneurysms, especially those located in the frontal lobe, with ICH and without cerebral herniation may be a feasible alternative and less invasive treatment.

AB - BACKGROUND: A recent randomized control study(the PATCH trial)found no beneficial effect of platelet concentrate(PC)transfusion on the prognosis of patients with intracerebral hemorrhage(ICH)treated with anti-platelet agents(APAs). However, the trial excluded surgical cases. In this study, we examined the effect of PC on ICH, including patients who received surgical treatment. METHOD: A retrospective cohort analysis was performed in 23(11 males, 12 females)of 35 patients diagnosed with ICH and treated with APAs between January 2010 and December 2015 at the Department of Neurosurgery, Yamaguchi University Hospital. Twelve patients were excluded due to the use of anticoagulants or replenishment of coagulation factors. RESULTS: PC transfusion was administered in 12 cases(PC group)but not administered in 11(non-PC group). Conservative therapy at admission was used in 7 and 9 cases in the PC and non-PC groups, respectively, and none of these cases showed hematoma enlargement during conservative therapy. Surgical treatment was performed in 6 and 2 patients in the PC and non-PC groups, respectively, and hematoma enlargement occurred postoperatively in one patient in each group. Outcomes at 3 months after onset showed no significant difference between the groups(mRS 0-3:6 vs. 5 cases, p=0.34). Patients who received PC had no serious adverse events during hospitalization. CONCLUSION: In this study, surgery after PC transfusion was performed without any problems. There was no difference in prognosis between patients who did and did not receive PC. These results suggest that surgery can be performed safely after PC transfusion. PMID- 29172202 TI - [Bilateral Pallidotomy for Tardive Dystonia:A Case Report]. AB - Tardive dystonia is a movement disorder related to the use of dopamine-receptor blocking drugs. Several reports have shown that deep brain stimulation of the globus pallidus internus(GPi-DBS)is effective in treating tardive dystonia. However, a few reports demonstrated the efficacy of ablation of the GPi(pallidotomy). We herein report a case of tardive dystonia successfully treated with bilateral pallidotomy. A 32-year-old man developed severe tardive dystonia 10 years after the chronic use of antipsychotic drugs. Withdrawal of the drugs and botulinum toxin injections were ineffective. The patient underwent bilateral pallidotomy for tardive dystonia because of rejection of the implanted DBS devices. Significant improvement was observed, with a 95% decrease in the Burke-Fahn-Marsden Dystonia Rating Scale(BFMDRS)movement score, and no severe adverse events occurred. Symptomatic relief persisted for nine months. Pallidotomy is a feasible and efficacious procedure for tardive dystonia treatment without the use of hardware implantations.

AB - A 46-year-old man presented with headache, right hemiparesis, and motor aphasia. A diagnosis of cerebral venous thrombosis with subarachnoid hemorrhage was made. We started intravenous administration of unfractionated heparin. After 6 days in hospital, the right hemiparesis and motor aphasia worsened, and brain computed tomographic(CT)images demonstrated intracerebral hemorrhage in the left parietal lobe. Therefore, we switched treatment from heparin to apixaban. His condition improved and a brain magnetic resonance(MR)venogram after 7 days in hospital showed recanalization of the cerebral veins. He was discharged with no apparent neurological defects 33 days after onset and his modified Rankin Scale score was 1. In cases of progressive cerebral venous thrombosis with intracerebral hemorrhage, during anticoagulation, it is necessary to achieve recanalization of the occluded cerebral vein rapidly without spreading the intracerebral hemorrhage. Factor Xa inhibitors, especially apixaban, may be another option for treating cerebral venous thrombosis with intracerebral hemorrhage.

AB - The spread of human immunodeficiency virus(HIV)infection may result in an increased likelihood of surgery in patients with HIV infection. We treated a patient with intracranial malignant lymphoma associated with acquired immunodeficiency syndrome(AIDS)caused by HIV infection. The recommendations of the countermeasure manual for AIDS were followed. Only surgical staff without finger injury or inflammation were permitted to be involved in the operation. All staff were dressed in a waterproof, full-body surgical gown, and wore double gloves, double foot covers, and an N95 mask. The surgery could be performed safely with such infection control measures. Histological examination revealed a diffuse large B-cell lymphoma. The patient was referred to the Division of Infectious Diseases and Respiratory Medicine for chemotherapy. PMID- 29172205 TI - [A Case of Multiple Atherosclerotic Fusiform Cerebral Aneurysms with Repeated Subarachnoid Hemorrhage]. AB - Pure fusiform aneurysms without dissection are considered to have a low risk of rupture. Furthermore, aneurysm wall with atherosclerotic change tends to be less susceptible to rupture. We present a rare case of multiple atherosclerotic fusiform aneurysms associated with repeated subarachnoid hemorrhage(SAH)during a 9-year observation period. A 34-year-old woman was admitted to our hospital because of SAH. SAH with a temporal hematoma due to a fusiform aneurysm of the right middle cerebral artery(MCA)was detected using computed tomography(CT). Associated fusiform aneurysms were observed in the left posterior cerebral artery(PCA)and the left MCA. The right MCA aneurysm was occluded with angioplastic clipping. Eight years after the first onset, angioplastic clipping was performed on the other two fusiform aneurysms because of their growth. Intraoperative findings showed atherosclerotic change in the parent artery wall, similar to the right MCA aneurysms. The right MCA aneurysm ruptured again 1 year later. The aneurysm was treated with proximal occlusion combined with a bypass from the occipital artery to the distal MCA. The patient was in a stable state, although, she was disabled because of SAH damage. The effects of atherosclerotic fusiform aneurysms, which are rarely encountered, are not well known. Some studies have reported the risk of hemorrhage from these aneurysms. This case suggests the necessity of long-term follow-up for the prediction of aneurysm growth and bleeding. Moreover, proximal occlusion combined with an external bypass is better for the treatment of this type of aneurysm because angioplastic clipping is not curative.

PMID- 29172212 TI - Effect of Sustained Use of Aspirin until the Time of Surgery on Outcomes following Coronary Artery Bypass Grafting: A Randomized Clinical Trial. AB - BACKGROUND: The topic of aspirin (acetylsalicylic acid, ASA) use in coronary artery disease patients planned for coronary artery bypass grafting during perioperative period is among the most disputed issues in cardiac surgery. We designed a study to weigh the risks and benefits of continued ASA ingestion until the time of surgery. METHODS: In this randomized double-blind clinical trial, 206 consecutive patients scheduled for isolated coronary artery bypass surgery (CABG) were randomly stratified into two groups. In group 1 (104 cases), patients were given 80 mg ASA per day until the day of surgery. In group 2 (102 patients), ASA (80 mg per day) was stopped 4 days before the operation. Patients in these two groups were similar in terms of preoperative patient and procedural characteristics. ASA was resumed 24 hours after the surgery in all patients. RESULTS: The rates of bleeding and reexploration within 24 hours of surgery were significantly higher in group 1 (824.3 vs. 492.1 mL, p < 0.001 and 5.7% vs. 0, p = 0.0138, respectively). The amount of intra- and postoperative packed red blood cell (PRBC) transfusion was considerably greater in group 1 (mean: 1.83 vs. 0.71 units, p < 0.001). The rate of hospital mortality was similar (1.9% in both the groups, p = 0.98). Patients in group 1 had significantly longer mean hospital stay than patients in group 2 (8 vs. 5.1 days, p < 0.001). Again the time interval between weaning from heart-lung machine and closing the sternum was strikingly longer in group 1 (mean: 32.1 vs. 14.5 minutes, p < 0.001). The incidence of adverse postoperative outcomes such as myocardial infarction, stroke, and renal failure was not statistically different between the two groups. CONCLUSION: Sustained ASA use until the day of surgery in patients planned for elective isolated CABG can result in excessive bleeding, increased rate of reexploration, and need for more PRBC transfusion without any proven beneficial effect on reducing unfavorable postoperative outcomes. Hence, we recommend discontinuing ASA between 3 and 5 days before non-urgent CABG while keeping it on in nonelective circumstances. PMID- 29172213 TI - In Situ Endothelialization Promoted by SEMA4D and CXCL12 for Titanium-Based Biomaterials. AB - In situ endothelialization, aiming to create implantation surfaces capable of self-endothelialization, seems to be an extremely promising solution, particularly on those blood-contacting surfaces. In this research study, we immobilized the soluble semaphorin 4D (SEMA4D) and C-X-C motif chemokine ligand 12 (CXCL12) biomolecules together with heparin onto the metal-based biomaterial surfaces to achieve in situ endothelialization of modified samples both by stimulating the neighboring endothelial cells (ECs) migration and by capturing the circulating endothelial progenitor cells (EPCs) directly from the blood circulation. X-ray photoelectron spectroscopy data demonstrate the successful immobilization of SEMA4D and CXCL12. Due to the presence of heparin, hemocompatibility was also improved after modification. Although EC migration was mainly mediated by SEMA4D with the coordination of CXCL12, EC proliferation and haptotaxis property were also enhanced, while EC chemotaxis was slightly suppressed because the further immobilization of CXCL12 influences the release of SEMA4D. The results of the ex vivo EPC capturing assay indicated the mobilization of CXCL12 promotes EPC adhesion. In vivo implantation further demonstrated that CXCL12 cooperates with SEMA4D to promote a process of in situ endothelialization. PMID- 29172214 TI - Complications of Implanted Nonbiologic Devices-An Overview. AB - Under physiologic conditions, blood is contained within the vascular space lined with smooth endothelial cells. When various devices made of nonbiologic material are implanted, blood will be exposed to a foreign surface. A series of events ensue and may lead to many complications, including thrombosis, hemolysis, thrombocytopenia, bleeding, infection, and malfunction of the device. The incidence, manifestations, and special characteristics of these complications vary with different types of implanted devices. However, they have in common an important pathogenic pathway that of an exposure to a foreign surface. Despite the development of improved versions of these devices, more research on the causative factors of these complications is needed to take preventive and corrective measures, particularly those that enhance the process of healing by re endothelialization of the foreign surface. This article is a brief review of the complications encountered in blood-contacting devices. PMID- 29172215 TI - Factor VII-Activating Protease: Hemostatic Protein or Immune Regulator? AB - Factor VII (FVII)-activating protease (FSAP) is a serine protease in plasma, which was initially described to play a role in coagulation by activation of FVII, independent of tissue factor, and in fibrinolysis by cleavage of single chain urokinase. Recent studies, however, suggest that FSAP-mediated FVII cleavage is negligible and that FSAP may exert procoagulant functions via cleavage of tissue factor pathway inhibitor. Meanwhile, many substrates of FSAP have been identified, such as platelet-derived growth factor, basic fibroblast growth factor/epidermal growth factor, histones, and high-molecular-weight kininogen. FSAP has also shown to induce DNA released from dead cells. Given its propensity for autoproteolysis and degradation, studies on the activation and regulation of FSAP are difficult to perform. Recent animal studies suggest a role of FSAP in the pathogenesis of arteriosclerosis, vascular integrity and probably also in the regulation of coagulation initiation. This review will focus on the biochemical properties of FSAP, regulation of FSAP activation, and finally its role in vascular disease and acute systemic inflammatory diseases, such as sepsis. PMID- 29172216 TI - The economic impact of using single-operator cholangioscopy for the treatment of difficult bile duct stones and diagnosis of indeterminate bile duct strictures. AB - BACKGROUND AND STUDY AIM: Conventional endoscopic retrograde cholangiopancreatography (ERCP) combines endoscopy and radiography to diagnose and treat pathological conditions of the bile duct. The aim of the present analysis was to evaluate the clinical and economic impact of the use of single operator intraductal cholangioscopy (IDC), which allows for direct visualization of the bile duct, as an alternative to ERCP for the treatment of difficult bile duct stones and the diagnosis of bile duct strictures. PATIENTS AND METHODS: The clinical and economic consequences of single-operator IDC use were evaluated using two decision-tree models, one for management of difficult-to-remove stones and one for stricture diagnosis. A hospital perspective was adopted. Data to populate the models were derived from two Belgian hospitals that specialize in endoscopic procedures of the bile duct. Overall, the examined population consisted of 62 patients with difficult stones and 49 patients with indeterminate strictures. RESULTS: In the model for difficult stone management, the use of IDC determined a decrease in the number of procedures (- 27 % relative reduction) and costs (- ?73 000; - 11 % relative reduction) when compared with ERCP. In the model for stricture diagnosis, the use of IDC determined a decrease in the number of procedures (- 31 % relative reduction) and costs (- ?13 000; - 5 % relative variation) when compared with ERCP. CONCLUSIONS: The single-operator IDC system performed better than ERCP for the treatment of difficult bile duct stones and the diagnosis of bile duct strictures, and reduced the overall expenditure in hospitals in Belgium.

AB - Demographic and social transformation occur due to changes in the structure of the population and employment especially of women, increasing cultural diversity, unequal educational opportunities for children and adolescents, and regional variation in the provision of services. Meeting the challenges requires flexible, responsive and integrated social and health care systems that allow participation of individuals and groups concerned and recognition of their views and perspectives.

The existing communication channels from sender to receiver are increasingly supplemented or even replaced by new forms of communication such as social media in all areas of life. Public Health must adopt these changes in order to make its concerns and results accessible to different user groups. 1. Many groups of the population (e. g. migrants, socially disadvantaged) are hard to reach for purposes of communication. Different addressees need different forms of communication, including social media. Appropriate access routes must be identified and used for communication. 2. Strategies must be developed on how public health information can be effectively communicated via social media. They must be professionally sound, reliable and quality-assured, and regular updating must ensured. 3. Participation and dialogue are important elements of effective public health communication.

AB - Public health research is application-oriented, its great potential lies in the interlinking of science and practice, as well as its interdisciplinarity and methodological competence. Public health research is focused on the development and evaluation of measures to protect and improve the health of the population. In doing so, it must make its contribution to tackling the new challenges posed by demographic change, digitalization, new forms of communication and medical progress. By pooling the forces, the public health scientists should actively contribute to policy advice and promoting adequate research funding.

AB - The need for a qualified public health workforce can only be met by appropriate provision of a wide spectrum of basic, advanced and continuing education and training programs on public health that meet international standards. At the same time, efforts must be made to offer young academics attractive career opportunities. Training in public health competences must also be provided for allied professionals in health care and for professions with influence on the determinants of health such as urban planning or agricultural science.

PMID- 29172222 TI - [Surveillance and Monitoring - Results of the Working Group 10 of the Forum Future Public Health, Berlin 2016]. AB - Evidence-based health policies and evidence-based measures need comprehensive information on the health of the population. The existing health surveillance system provides reliable answers to many health policy issues. Nonetheless, there are many information gaps not yet covered or are only covered via short-term project solutions. 1. We need to strengthen and expand existing health surveillance and monitoring to continuously collect information on the health status of all population groups, including those that are difficult to reach through the existing surveys and methods, such as people with a migration background, or socially disadvantaged. This information must be regularly available on the national, regional and also on the local level. 2. The use of existing data on health, for example from official statistics or social insurance, must be significantly expanded and strengthened. The infrastructure for scientific analyses of health data as well as the transfer of information to policy makers and the public must be strengthened. Through an expansion of the resources for scientific processing of health-relevant questions, Public Health can make an important contribution to effective health policies.

A Good Governance approach for health has not yet been developed. The main areas of action would be the establishment of a health impact assessment for proposed legislation, the expansion of public health services and a new role for structural interventions for disease prevention and health promotion. It is also necessary to focus government action on the provision of public health services and - related to that - on strengthening the municipal level as a relevant decision-making structure for health.

AB - Heterogeneity is a constitutive element of public health practice in Germany. The Public Health Service as a traditional field of public health is - like the currently booming health promotion and disease prevention landscape - faced with major challenges in its attempt to create more health for vulnerable population groups. Additional expenditure on small-scale prevention concepts and interventions and vastly differentiated job profiles are not per se beneficial to achieve this aim. The future of public health practice lies rather in the development of integrated communal concepts of action such as prevention chains.

AB - The Public Health White Paper draws up a vision of public health as a living, decentralized network that can help improve the health of the population in a sustained fashion. However, the central question remains open as to which prerequisites public health networks should fulfill in order to be effective in the long term. The aim of this paper is to provide a sociological view of the issue and offer some discussion ideas. Parsons' structural functionalism leads to the thesis that science networks in public health require structures that ensure that the 4 basic functions of viable social networks - (1) adaptation, (2) goal attainment, (3) integration and (4) latent pattern maintenance - are fulfilled. On this theoretical basis, suggestions are made to establish functional formal structures in public health networks. PMID- 29172228 TI - Adverse life events increase risk for postpartum psychiatric episodes: A population-based epidemiologic study. AB - BACKGROUND: Trauma histories may increase risk of perinatal psychiatric episodes. We designed an epidemiological population-based cohort study to explore if adverse childhood experiences (ACE) in girls increases risk of later postpartum psychiatric episodes. METHODS: Using Danish registers, we identified women born in Denmark between January 1980 and December 1998 (129,439 childbirths). Exposure variables were ACE between ages 0 and 15 including: (1) family disruption, (2) parental somatic illness, (3) parental labor market exclusion, (4) parental criminality, (5) parental death, (6) placement in out-of-home care, (7) parental psychopathology excluding substance use, and (8) parental substance use disorder. Primary outcome was first occurrence of in- or outpatient contact 0-6 months postpartum at a psychiatric treatment facility with any psychiatric diagnoses, ICD-10, F00-F99 (N = 651). We conducted survival analyses using Cox proportional hazard regressions of postpartum psychiatric episodes. RESULTS: Approximately 52% of the sample experienced ACE, significantly increasing risk of any postpartum psychiatric diagnosis. Highest risks were observed among women who experienced out-of-home placement, hazard ratio (HR) 2.57 (95% CI: 1.90-3.48). Women experiencing two adverse life events had higher risks of postpartum psychiatric diagnosis HR: 1.88 (95% CI: 1.51-2.36), compared to those with one ACE, HR: 1.24 (95% CI: 1.03-49) and no ACE, HR: 1.00 (reference group). CONCLUSIONS: ACE primarily due to parental psychopathology and disability contributes to increased risk of postpartum psychiatric episodes; and greater numbers of ACE increases risk for postpartum psychiatric illness with an observed dose-response effect. Future work should explore genetic and environmental factors that increase risk and/or confer resilience. PMID- 29172229 TI - Context matters: a multicountry analysis of individual- and neighbourhood-level factors associated with women's sanitation use in sub-Saharan Africa. AB - OBJECTIVES: To identify cross-national trends in factors associated with women's sanitation use in sub-Saharan Africa. METHODS: Using data from Demographic and Health Surveys conducted in 14 SSA countries between 2008 and 2014, we modelled women's sanitation use in relation to various individual- and neighbourhood-level factors. RESULTS: Substantial variation exists between countries in the strength and direction of factors associated with sanitation use. Particularly significant associations across the region included access to different water sources, years of education, family size, age, living in a female-headed household, being married and wealth. Neighbourhood-level poverty, ethnic diversity and urbanisation were important factors in a majority of countries. CONCLUSIONS: International development goals for sanitation are frequently framed in terms of availability, implicitly suggesting that if facilities are accessible, they will be used. A more nuanced view that takes into account not only the existence of facilities but also the factors influencing their use is needed to understand the dynamics of women's sanitation use in the region. Policies focused on availability may not yield the desired public health benefits from improved sanitation in sub-Saharan Africa. Context-relevant factors must be addressed concurrently to achieve sanitation development goals. PMID- 29172227 TI - Apolipoprotein E gene polymorphism, trauma burden, and posttraumatic stress symptoms in U.S. military veterans: Results from the National Health and Resilience in Veterans Study. AB - BACKGROUND: Previous research examining the association between apolipoprotein E (APOE) gene polymorphism and risk for posttraumatic stress disorder (PTSD) has been inconsistent due to the use of small and select samples. This study examined the relation between APOE genotype and PTSD symptoms in two nationally representative samples of U.S. military veterans. The potential effect of cumulative trauma burden and social support in moderating this association was also evaluated. METHODS: The main sample consisted of 1,386 trauma-exposed European American (EA) veterans (mean age: 62-63 years) who participated in the National Health and Resilience in Veterans Study (NHRVS) in 2011. The independent replication sample consisted of 509 trauma-exposed EA veterans from the 2013 NHRVS. RESULTS: APOE epsilon4 allele carriers reported significantly greater severity of PTSD symptoms than noncarriers in the main, but not the replication, sample. In both samples, the interaction of APOE epsilon4 carrier status and cumulative trauma burden was associated with greater severity of PTSD symptoms (F range = 2.53-8.09, all P's < .01), particularly re-experiencing/intrusion symptoms (F range = 3.59-4.24, P's < .001). Greater social support was associated with lower severity of PTSD symptoms among APOE epsilon4 allele carriers with greater cumulative trauma burden (beta range -.27 to -.60, P's < .05). CONCLUSION: U.S. military veterans who are APOE epsilon4 allele carriers and exposed to a high number of traumas may be at increased risk for developing PTSD symptoms than epsilon4 noncarriers. Greater social support may moderate this association, thereby highlighting the potential importance of social support promoting interventions in mitigating the effect of epsilon4 * cumulative trauma burden on PTSD risk. PMID- 29172230 TI - Sequential gene activation and gene imprinting during early embryo development in maize. AB - Gene imprinting is a widely observed epigenetic phenomenon in maize endosperm; however, whether it also occurs in the maize embryo remains controversial. Here, we used high-throughput RNA sequencing on laser capture microdissected and manually dissected maize embryos from reciprocal crosses between inbred lines B73 and Mo17 at six time points (3-13 days after pollination, DAP) to analyze allelic gene expression patterns. Co-expression analysis revealed sequential gene activation during maize embryo development. Gene imprinting was observed in maize embryos, and a greater number of imprinted genes were identified at early embryo stages. Sixty-four strongly imprinted genes were identified (at the threshold of 9:1) on manually dissected embryos 5-13 DAP (more imprinted genes at 5 DAP). Forty-one strongly imprinted genes were identified from laser capture microdissected embryos at 3 and 5 DAP (more imprinted genes at 3 DAP). Furthermore, of the 56 genes that were completely imprinted (at the threshold of 99:1), 36 were not previously identified as imprinted genes in endosperm or embryos. In situ hybridization demonstrated that most of the imprinted genes were expressed abundantly in maize embryonic tissue. Our results shed lights on early maize embryo development and provide evidence to support that gene imprinting occurs in maize embryos. PMID- 29172231 TI - Children with optic nerve hypoplasia face a high risk of neurodevelopmental disorders. AB - AIM: Optic nerve hypoplasia (ONH) is a congenital ocular malformation that has been associated with neurodevelopmental disorders, but the prevalence in unilateral disease and less severe visual impairment is unknown. We studied intellectual disability and autism spectrum disorders (ASDs) in patients with ONH. METHODS: This was a population-based cross-sectional cohort study of 65 patients (33 female) with ONH below 20 years of age, living in Stockholm in December 2009, with data analysed in January 2016. Of these 35 were bilateral and 30 were unilateral. Neurodevelopmental disorders were diagnosed or confirmed by neurological assessments, the Five to Fifteen parent questionnaire and reviewing previous neuropsychological investigations or conducting neuropsychological tests. RESULTS: Bilateral ONH patients had lower mean full scale intelligence quotient scores than unilateral patients (84.4 and 99.4, respectively, p = 0.049). We assessed intellectual disability in 55 eligible patients, and it was more common in patients with bilateral ONH (18 of 32, 56%) than unilateral ONH (two of 23, 9%, p < 0.001). ASDs were diagnosed in seven of 42 (17%) patients. CONCLUSION: Children with bilateral ONH had a high risk of neurodevelopmental disorders, especially intellectual disability. The risk was lower in unilateral ONH, but the levels of neurodevelopmental disorders warrant screening of both groups. PMID- 29172232 TI - Review demonstrates that less invasive surfactant administration in preterm neonates leads to fewer complications. AB - : Surfactant treatment of neonatal respiratory distress syndrome (RDS) was introduced in Europe during the 1990s. Meta-analyses have indicated that using less invasive surfactant administration techniques on preterm neonates receiving continuous positive airway pressure (CPAP) results in improved survival rates without bronchopulmonary dysplasia. Surfactant should be administered early and ventilator settings adapted to changing oxygen requirements and lung mechanics. Side effects including initial bradycardia, oxygen desaturation, tube obstruction and isolated cases of pulmonary haemorrhage have been reported. CONCLUSION: Less invasive surfactant therapy improves pulmonary outcomes in preterm neonates with RDS and should ideally be administered in combination with CPAP. PMID- 29172233 TI - Stronger selective constraint on downstream genes in the oxidative phosphorylation pathway of cetaceans. AB - The oxidative phosphorylation (OXPHOS) pathway is an efficient way to produce energy via adenosine triphosphate (ATP), which is critical for sustaining an energy supply for cetaceans in a hypoxic environment. Several studies have shown that natural selection may shape the evolution of the genes involved in OXPHOS. However, how network architecture drives OXPHOS protein sequence evolution remains poorly explored. Here, we investigated the evolutionary patterns of genes in the OXPHOS pathway across six cetacean genomes within the framework of a functional network. Our results show a negative correlation between the strength of purifying selection and pathway position. This result indicates that downstream genes were subjected to stronger evolutionary constraints than upstream genes, which may be due to the dual function of ATP synthase in the OXPHOS pathway. Additionally, there was a positive correlation between codon usage bias and omega (omega = dN/dS) and a negative correlation with synonymous substitution rate (dS), indicating that the stronger selective constraint on genes (with less biased codon usage) along the OXPHOS pathway is attributable to an increase in the rate of synonymous substitution. Surprisingly, there was no significant correlation between protein-protein interactions and the evolutionary estimates, implying that highly connected enzymes may not always show greater evolutionary constraints. Compared with that observed for terrestrial mammals, we found that the signature of positive selection detected in five genes (ATP5J, LHPP, PPA1, UQCRC1 and UQCRQ) was cetacean-specific, reflecting the importance of OXPHOS for survival in hypoxic, aquatic environments.

AB - BACKGROUND: Atopic dermatitis (AD) and hand eczema (HE) are common chronic and relapsing inflammatory skin conditions that often co-occur. OBJECTIVES: While several studies have addressed their relationship, the exact association estimate is unknown. METHODS: We systematically reviewed published literature on the association between AD and HE in PubMed, Embase and Web of Science using the following search terms: (atopic dermatitis OR atopic eczema) AND (hand dermatitis OR hand eczema). Meta-analyses were then performed to examine the association between AD and the point, 1-year and lifetime prevalence of HE, respectively. RESULTS: We identified 35 relevant studies, of which 26 were included in the meta analyses. AD was associated with an increased prevalence of HE with regard to point [odds ratio (OR) 2.35; 95% confidence interval (CI) 1.47-3.76], 1-year (OR 4.29; 95% CI 3.13-5.88) and lifetime prevalence (OR 4.06; 95% CI 2.72-6.06). Furthermore, positive associations between AD and occupational HE were identified when assessing the 1-year (OR 4.31; 95% CI 2.08-8.91) and lifetime prevalence (OR 2.81; 95% CI 2.08-3.79). Similar positive associations were found in the general population studies, i.e. OR 4.19 (95% CI 3.46-5.08) and OR 5.69 (95% CI 4.41 7.36). CONCLUSIONS: Important study limitations include the wide use of questionnaire studies, and lack of prospective studies as well as poor clinical phenotype descriptions. In conclusion, our systematic review and meta-analysis showed that patients with AD had a strongly increased prevalence of HE. Clinicians should continue to guide patients with AD away from occupations with a high risk of HE.

AB - AIM: An airtight anastomosis on intra-operative leak testing has been previously demonstrated to be associated with a lower risk of clinically significant postoperative anastomotic leak following left-sided colorectal anastomosis. However, to date, there is no consistently agreed upon method for management of an intra-operative anastomotic leak. Therefore, we powered a noninferiority study to determine whether suture repair alone was an appropriate strategy for the management of an intra-operative air leak. METHOD: This is a retrospective cohort analysis of prospectively collected data from a tertiary care referral centre. We included all consecutive patients with left-sided colorectal or ileorectal anastomoses and evidence of air leak during intra-operative leak testing. Patients were excluded if proximal diversion was planned preoperatively, a pre existing proximal diversion was present at the time of surgery or an anastomosis was ultimately unable to be completed. The primary outcome measure was clinically significant anastomotic leak, as defined by the Surgical Infection Study Group at 30 days. RESULTS: From a sample of 2360 patients, 119 had an intra-operative air leak during leak testing. Sixty-eight patients underwent suture repair alone and 51 underwent proximal diversion or anastomotic reconstruction. The clinically significant leak rate was 9% (6/68; 95% CI: 2-15%) in the suture repair alone arm and 0% (0/51) in the diversion or reconstruction arm. CONCLUSION: Suture repair alone does not meet the criteria for noninferiority for the management of intra operative air leak during left-sided colorectal anastomosis. Further repair of intra-operative air leak by suture repair alone should be reconsidered given these findings. PMID- 29172237 TI - Estimation and validation of patient-specific high-resolution lung elasticity derived from 4DCT. AB - PURPOSE: Lung diseases are commonly associated with changes in lung tissue's biomechanical properties. Functional imaging techniques, such as elastography, have shown great promise in measuring tissue's biomechanical properties, which could expand the utility and effectiveness of radiotherapy treatment planning. We present a novel methodology for characterizing a key biomechanical property, parenchymal elasticity, derived solely from 4DCT datasets. METHODS: Specifically, end-inhalation and end-exhalation breathing phases of the 4DCT datasets were deformably registered and the resulting displacement maps were considered to be ground-truth. A mid-exhalation image was also prepared for verification purposes. A GPU-based biomechanical model was then generated from the patient end exhalation dataset and used as a forward model to iteratively solve for the elasticity distribution. Displacements at the surface of the lungs were applied as boundary constraints for the model-guided tissue elastography, while the inner voxels were allowed to deform according to the linear elastic forces within the biomechanical model. A convergence criteria of 10% maximum deformation was employed for the iterative process. RESULTS: The lung tissue elasticity estimation was documented for a set of 15 4DCT patient datasets. Maximum lung deformations were observed to be between 6 and 31 mm. Our results showed that, on average, 89.91 +/- 4.85% convergence was observed. A validation study consisting of mid-exhalation breathing phases illustrated an accuracy of 87.13 +/- 10.62%. Structural similarity, normalized cross-correlation, and mutual information were used to quantify the degree of similarity between the following image pairs: (a) the model-generated end-exhalation and ground-truth end-exhalation, and (b) model generated mid-exhalation images and ground-truth mid-exhalation. CONCLUSIONS: Overall, the results suggest that the lung elasticity can be measured with approximately 90% convergence using routinely acquired clinical 4DCT scans, indicating the potential for a lung elastography implementation within the radiotherapy clinical workflow. The regional lung elasticity found here can lead to improved tissue sparing radiotherapy treatment plans, and more precise monitoring of treatment response. PMID- 29172238 TI - Women who had positive relationships with their own mothers reported good attachments to their first child before and after birth. AB - AIM: Bowlby's attachment intergenerational transmission theory suggests that a woman's attachment to her parents, particularly her mother, plays an important role in her future parenting. We studied whether there was any association between pregnant women's attachment to their baby before and after birth and their relationships with their mothers. METHODS: A longitudinal study was carried out in 2015 on 201 first-time mothers recruited in the maternity ward of the level two Misericordia e Dolce Hospital in Prato, Italy. At 32 weeks of pregnancy, the women filled in the Parental Bonding Instrument and the Prenatal Attachment Inventory and their spontaneous attachment behaviour towards their newborn infants were observed in the nursery during the first two days after childbirth. RESULTS: Having a good relationship with their own mothers was a positive predictor for the women's prenatal attachment to their baby and caregiving and attachment behaviour to their newborn infants. In addition, the mothers' prenatal attachment positively predicted their behavioural attachment pattern after birth. CONCLUSION: We found that women who had positive relationships with their own mothers also had positive attachments to their unborn babies and in the period immediately after birth. Our findings supported Bowlby's attachment intergenerational transmission theory. PMID- 29172239 TI - Strictly controlled glucose infusion rates are associated with a reduced risk of hyperglycaemia in extremely low birth weight preterm infants. AB - AIM: We evaluated a strict strategy that aimed to avoid fluctuations in glucose infusion rates (GIRs) and assessed the independent effects of maximal daily GIRs on the hyperglycaemia risk among extremely low birth weight (ELBW) infants receiving early enhanced parenteral nutrition. METHODS: This study comprised all ELBW infants admitted to the neonatal intensive care unit of Oslo University Hospital Rikshospitalet, Norway, before (2007-2009) and after (2012-2013) implementing a strict GIR strategy. Severe hyperglycaemia was defined as two consecutive blood glucose values over 12 mmol/L. Maximum daily GIRs (mg/kg/min) were categorised into low (<5.1), intermediate (5.1-7.0) or high (>7.0). Mixed effects logistic regression modelling for repeated measurements was applied to investigate independent determinants of hyperglycaemia. RESULTS: We included 1293 treatment days for 195 infants. The maximum daily GIR decreased (6.3 versus 5.8 mg/kg/min), while mean daily glucose and energy intakes were maintained in the post-strategy period. The prevalence of severe hyperglycaemia (48% versus 23%), insulin use (39% versus 16%) and mortality (26% versus 10%) fell. Intermediate GIR (odds ratio 2.11) and high GIR (odds ratio 2.85) were significant independent predictors of severe hyperglycaemia compared to low GIR. CONCLUSION: A strict GIR strategy reduced the risk of severe hyperglycaemia and adverse outcomes. PMID- 29172240 TI - Disseminated mucormycosis masquerading as rejection early after orthotopic heart transplantation. AB - Mucorales organisms are an uncommon cause of invasive fungal infections after solid organ transplantation but are associated with great morbidity and mortality. We report a fatal case of disseminated Cunninghamella infection early after heart transplantation. The patient developed graft dysfunction and elevated markers of myocyte injury and autopsy revealed fulminant fungal myocarditis. This case highlights the need for a high index of suspicion in immunocompromised patients who are not improving with standard antimicrobial therapy. PMID- 29172241 TI - The impact of resilience and subsequent stressful life events on MDD and GAD. AB - BACKGROUND: There remains a dearth of research examining the "buffering" effect of resilience, wherein resilience at one point in time would be expected to protect an individual against development of psychopathology following future adverse life events. METHODS: Using longitudinal data from an epidemiological twin sample (N = 7463), this study tested whether resilience would act as a buffer for stressful life events (SLEs) against risk for major depressive disorder (MDD) and generalized anxiety disorder (GAD). Resilience, demographics, and psychopathology were measured at Time 1 and recent SLEs and current MDD and GAD were measured at Time 2. RESULTS: Final models, controlling for demographic covariates and Time 1 diagnosis, examined the impact of Time 1 resilience, recent SLEs, their interaction, and a three-way interaction adding sex on MDD and GAD. CONCLUSIONS: The pattern of findings was the same for MDD and GAD, wherein main effects and two-way interactions of resilience and SLEs were significant, such that greater resilience was protective even in the context of high numbers of past-year SLEs. The three-way interaction was not significant, suggesting that the relationship between SLEs and resilience on psychopathology was the same for both men and women. Findings support the conceptualization of resilience as a buffer against the impact of future life stressors on common internalizing psychopathology. Longitudinal designs and trajectory-based studies that include recurring measures of SLEs could inform conceptualizations of resilience in the context of ongoing adversity and aid in developing interventions aimed at fostering healthy adaptation in the face of stressors. PMID- 29172242 TI - Upregulation of angiogenesis in oral lichen planus. AB - OBJECTIVES: As angiogenesis is fundamental to the pathogenesis of many chronic inflammatory disorders, this study investigated the expression of various vascular markers in oral lichen planus and non-specific oral mucosal inflammatory tissues. METHODS: Archival specimens of oral lichen planus (n = 15) and inflamed tissues (n = 13) were stained using immunohistochemistry with antibodies to CD34, vascular endothelial growth factor, vascular endothelial growth factor receptor and vasohibin. Nine representative sites at the epithelial-connective tissue junction and through the fibrous connective tissue were selected, and automated analysis techniques were used to determine the extent of positivity expressed as the percentage of positive cells. Significance was denoted when P < .05. RESULTS: The expression of pro-angiogenic factors was higher in lichen planus samples compared with inflamed controls. A higher level of CD34 was observed in the deeper parts of the connective tissue of Oral lichen planus (OLP) (P = .04), whereas VEGF and VEGFR2 expressions were higher all through the tissues (respectively, P < .02 and P < .01). The expression of the anti-angiogenic VASH1 was higher in inflamed tissue compared with lichen planus in all sites evaluated (P < .01). CONCLUSIONS: The findings indicate that angiogenic factors are differentially expressed in oral lichen planus compared with inflamed controls, with increased expression of pro-angiogenic factors and decreased anti-angiogenic expression. PMID- 29172243 TI - Characterization of 90 Y-SPECT/CT self-calibration approaches on the quantification of voxel-level absorbed doses following 90 Y-microsphere selective internal radiation therapy. AB - PURPOSE: 90 Y-microsphere selective internal radiation therapy (90 Y-SIRT or 90 Y radioembolization) is used in the management of unresectable liver tumors. 90 Y SIRT presents a unique situation where the total 90 Y activity inside the liver can be determined with high accuracy (> 95%). 90 Y bremsstrahlung single-photon emission computed tomography (SPECT)/computed tomography (CT) can be self calibrated to provide quantitative images that facilitate voxel-level absorbed dose calculations. We investigated the effects of different approaches for 90 Y SPECT self-calibration on the quantification of absorbed doses following 90 Y SIRT. METHODS: 90 Y bremsstrahlung SPECT/CT images of 31 patients with hepatocellular carcinoma, collected following 90 Y-SIRT, were analyzed, yielding 48 tumor and 31 normal liver contours. We validated the accuracy of absorbed doses calculated by a commercial software against those calculated using Monte Carlo-based radiation transport. The software package was used to analyze the following definitions of SPECT volume of interest used for 90 Y-SPECT self calibration: (a) SPECT field-of-view (FOV), (b) chest-abdomen contour, (c) total liver contour, (d) total liver contour expanded by 5 mm, and (e) total liver contour contracted by 5 mm. Linear correlation and Bland-Altman analysis were performed for tumor and normal liver tissue absorbed dose volume histogram metrics between the five different approaches for 90 Y-SPECT self-calibration. RESULTS: The mean dose calculated using the commercial software was within 3% of Monte Carlo for tumors and normal liver tissues. The tumor mean dose calculated using the chest-abdomen calibration was within 2% of that calculated using the SPECT FOV, whereas the doses calculated using the total liver contour, expanded total liver contour, and contracted total liver contour were within 68%, 47%, and 107%, respectively, of doses calculated using the SPECT FOV. The normal liver tissue mean dose calculated using the chest-abdomen contour was within 1.3% of that calculated using the SPECT FOV, whereas the doses calculated using the total liver contour, expanded total liver contour, and contracted total liver contour were within 73%, 50%, and 114%, respectively, of doses calculated using the SPECT FOV. CONCLUSIONS: The mean error of < 3% for commercial software can be considered clinically acceptable for 90 Y-SIRT dosimetry. Absorbed dose quantification using 90 Y-SPECT self-calibration with the chest-abdomen contour was equivalent to that calculated using the SPECT FOV, but self-calibration with the total liver contour yielded substantially higher (~70%) dose values. The large biases revealed by our study suggest that consistent absorbed dose calculation approaches are essential when comparing 90 Y-SIRT dosimetry between different clinical studies. PMID- 29172244 TI - Comparative study of amlodipine vs. cilnidipine for the prevention of hepatic ischemia-reperfusion injury in rat model. AB - Ca2+ signaling plays crucial role in ischemia and reperfusion (I/R) injury. Although blockade of L-type Ca2+ channels by amlodipine (AML) has been shown to suppress hepatic I/R injury in several animal models, information is still needed regarding the hepatoprotective effects of the dual L/N-type Ca2+ channel blockers, cilnidipine (CIL). We examined the effect of pretreatment with AML or CIL (100 MUg/kg i.p.) 45 min before induction of 60 min of liver ischemia followed by reperfusion, on oxidative stress markers, liver enzymes, serum tumor necrosis factor-alpha, interleukin-1beta, apoptosis markers, and nuclear factor KB after 6 and 24 h of hepatic reperfusion. Both drugs significantly ameliorated biochemical and histological markers of hepatic I/R injury, but protection with CIL was more significant at the 6-h time point where protection with AML outlasted that of CIL. Both drugs offered significant protection against hepatic I/R damage, but the protection with CIL seemed more potent but of shorter duration than that observed with AML possibly due to the shorter half-life of CIL. PMID- 29172246 TI - Obese children aged 4-6 displayed decreased fasting and postprandial ghrelin levels in response to a test meal. AB - AIM: Ghrelin is a hunger hormone that plays a role in glucose homoeostasis and its levels increase before a meal and decrease during and after eating. This study compared the fasting ghrelin and insulin levels of obese children aged 4-6 with those of normal weight children and tested postprandial ghrelin levels in the obese children after a standard breakfast. METHODS: We recruited 67 children at Lund University Hospital from 2008 to 2011. They comprised 30 obese children from a weight study and 37 normal weight children receiving minor elective surgery. Their mean ages were 4.7 +/- 0.6 and 4.3 +/- 0.8 years, respectively. The obese children ate a standard breakfast, and postprandial ghrelin was measured after 60 minutes. RESULTS: The obese children had lower ghrelin levels than the controls (p < 0.01). A significant inverse relation was found between body mass index and fasting ghrelin levels. Obese children had significantly lower fasting ghrelin levels after a standard breakfast (p < 0.01), but there were no gender-related differences. CONCLUSION: Obese children aged 4-6 years had reduced ghrelin and increased insulin levels in the fasting state and postprandial ghrelin was suppressed, suggesting that their energy metabolism was already dysregulated at this young age. Early obesity interventions are essential. PMID- 29172245 TI - The Swedish Pregnancy Register - for quality of care improvement and research. AB - INTRODUCTION: The objective of this study was to present the Swedish Pregnancy Register and to explore regional differences in maternal characteristics, antenatal care, first trimester combined screening and delivery outcomes in Sweden. MATERIAL AND METHODS: The Pregnancy Register (www.graviditetsregistret.se) collects data on pregnancy and childbirth, starting at the first visit to antenatal care and ending at the follow-up visit to the antenatal care, which usually occurs at around 8-16 weeks postpartum. The majority of data is collected directly from the electronic medical records. The Register includes demographic, reproductive and maternal health data, as well information on prenatal diagnostics, and pregnancy outcome for the mother and the newborn. RESULTS: Today the Register covers more than 90% of all deliveries in Sweden, with the aim to include all deliveries within 2018. The care providers can visualize quality measures over time and compare results with other clinics, regionally and nationally by creating reports on an aggregated level or using case-mix adjusted Dash Boards in real time. Detailed data can be extracted after ethical approval for research. In this report, we showed regional differences in patient characteristics, antenatal care, fetal diagnosis and delivery outcomes in Sweden. CONCLUSIONS: Our report indicates that quality in antenatal and delivery care in Sweden varies between regions, which warrants further actions. The Swedish Pregnancy Register is a new and valuable resource for benchmarking, quality improvement and research in pregnancy, fetal diagnosis and delivery. PMID- 29172247 TI - The target of rapamycin kinase affects biomass accumulation and cell cycle progression by altering carbon/nitrogen balance in synchronized Chlamydomonas reinhardtii cells. AB - Several metabolic processes tightly regulate growth and biomass accumulation. A highly conserved protein complex containing the target of rapamycin (TOR) kinase is known to integrate intra- and extracellular stimuli controlling nutrient allocation and hence cellular growth. Although several functions of TOR have been described in various heterotrophic eukaryotes, our understanding lags far behind in photosynthetic organisms. In the present investigation, we used the model alga Chlamydomonas reinhardtii to conduct a time-resolved analysis of molecular and physiological features throughout the diurnal cycle after TOR inhibition. Detailed examination of the cell cycle phases revealed that growth is not only repressed by 50%, but also that significant, non-linear delays in the progression can be observed. By using metabolomics analysis, we elucidated that the growth repression was mainly driven by differential carbon partitioning between anabolic and catabolic processes. Accordingly, the time-resolved analysis illustrated that metabolic processes including amino acid-, starch- and triacylglycerol synthesis, as well RNA degradation, were redirected within minutes of TOR inhibition. Here especially the high accumulation of nitrogen-containing compounds indicated that an active TOR kinase controls the carbon to nitrogen balance of the cell, which is responsible for biomass accumulation, growth and cell cycle progression. PMID- 29172248 TI - Differential involvement of ipsilateral and contralateral spinal cord astrocyte D serine in carrageenan-induced mirror-image pain: role of sigma1 receptors and astrocyte gap junctions. AB - BACKGROUND AND PURPOSE: Although we have recently demonstrated that spinal astrocyte gap junctions mediate the development of mirror-image pain (MIP), it is still unclear which astrocyte-derived factor is responsible for the development of MIP and how its production is controlled. In the present study, we focused on the role of ipsilateral versus contralateral D-serine in the development of MIP and investigated the possible involvement of sigma1 receptors and gap junctions in astrocyte D-serine production. EXPERIMENTAL APPROACH: Following carrageenan injection, mechanical allodynia was tested at various time points to examine the effect of individual drugs. Immunohistochemistry and Western blot analyses were performed to clarify the expression levels of spinal D-serine, serine racemase, sigma1 receptors and connexin 43. KEY RESULTS: The expression of ipsilateral D serine was up-regulated during the early phase of inflammation, while contralateral D-serine increased during the later phase of inflammation. The pharmacological inhibition of D-serine during the early phase blocked the development of both ipsilateral and contralateral mechanical allodynia. However, the inhibition of D-serine during the later phase of inflammation blocked contralateral, but not ipsilateral mechanical allodynia. Furthermore, the inhibition of sigma1 receptors during the earlier phase of inflammation inhibited the increase in ipsilateral D-serine. Conversely, the blockade of astrocyte gap junctions suppressed the up-regulation of contralateral D-serine during the later phase of inflammation. CONCLUSION AND IMPLICATIONS: Spinal astrocyte D-serine plays an important role in the development of mirror-image pain. Furthermore, sigma1 receptors and astrocyte gap junction signalling mediate ipsilateral and contralateral D-serine production respectively. PMID- 29172249 TI - Depressive symptoms prior to and after incident cardiovascular disease and long term survival. A population-based study of older persons. AB - BACKGROUND: Depression after a cardiovascular disease event (post-CVD) is associated with increased mortality. However, little is known about how pre existing depression affects survival after CVD incidence. AIM: To evaluate whether depressive symptoms preceding first incident CVD (pre-CVD) affects survival. METHODS: From the Rotterdam Study, 6,932 persons aged 55+ and free of dementia and CVD completed the Center for Epidemiological Studies Depression (CES D) scale every 4 to 5 years from 1993. CES-D subdomains were positive affect, negative affect, somatic symptoms, and interpersonal affect. Persons were followed for mortality and CVD. RESULTS: During 15-year follow-up, 22% of participants suffered their first incident CVD. Pre-CVD depressive symptoms was not associated with mortality after adjustment for smoking status and physical function (HR per 10-point score: 1.05, 95%CI: 0.99-1.10). After first incident CVD, depressive symptoms increased. Higher post-CVD depressive symptoms was associated with increased mortality (HR: 1.13, 95%CI: 1.06, 1.22). The relation between post-CVD depressive symptoms and mortality was no longer statistically significant after adjustment for pre-CVD depressive symptoms. Pre-CVD and post CVD measures of somatic symptoms and positive affect were associated with mortality. CONCLUSIONS: During 15 years follow-up in community-dwelling older adults, the relation between higher depressive symptoms measured before first incident CVD and mortality was not independent of health status. Whereas, higher depressive symptoms measured after CVD was associated with increased mortality, was not independent of pre-CVD depressive symptoms. Given the associations observed between positive affect and mortality, positive affect may be the reason we observed a relation between depressive symptoms and mortality. PMID- 29172250 TI - High-throughput sequencing of the chloroplast and mitochondrion of Chlamydomonas reinhardtii to generate improved de novo assemblies, analyze expression patterns and transcript speciation, and evaluate diversity among laboratory strains and wild isolates. AB - Chlamydomonas reinhardtii is a unicellular chlorophyte alga that is widely studied as a reference organism for understanding photosynthesis, sensory and motile cilia, and for development of an algal-based platform for producing biofuels and bio-products. Its highly repetitive, ~205-kbp circular chloroplast genome and ~15.8-kbp linear mitochondrial genome were sequenced prior to the advent of high-throughput sequencing technologies. Here, high coverage shotgun sequencing was used to assemble both organellar genomes de novo. These new genomes correct dozens of errors in the prior genome sequences and annotations. Genome sequencing coverage indicates that each cell contains on average 83 copies of the chloroplast genome and 130 copies of the mitochondrial genome. Using protocols and analyses optimized for organellar transcripts, RNA-Seq was used to quantify their relative abundances across 12 different growth conditions. Forty six percent of total cellular mRNA is attributable to high expression from a few dozen chloroplast genes. RNA-Seq data were used to guide gene annotation, to demonstrate polycistronic gene expression, and to quantify splicing of psaA and psbA introns. In contrast to a conclusion from a recent study, we found that chloroplast transcripts are not edited. Unexpectedly, cytosine-rich polynucleotide tails were observed at the 3'-end of all mitochondrial transcripts. A comparative genomics analysis of eight laboratory strains and 11 wild isolates of C. reinhardtii identified 2658 variants in the organellar genomes, which is 1/10th as much genetic diversity as is found in the nucleus. PMID- 29172251 TI - On computational fluid dynamics models for sinonasal drug transport: Relevance of nozzle subtraction and nasal vestibular dilation. AB - Generating anatomically realistic 3-dimensional (3D) models of the human sinonasal cavity for numerical investigations of sprayed drug transport presents a host of methodological ambiguities. For example, subject-specific radiographic images used for 3D reconstructions typically exclude spray bottles. Subtracting a bottle contour from the 3D airspace and dilating the anterior nasal vestibule for nozzle placement augment the complexity of model building. So we explored the question: how essential are these steps to adequately simulate nasal airflow and identify the optimal delivery conditions for intranasal sprays? In particular, we focused on particle deposition patterns in the maxillary sinus, a critical target site for chronic rhinosinusitis. The models were reconstructed from postsurgery computed tomography scans for a 39-year-old Caucasian male, with chronic rhinosinusitis history. Inspiratory airflow patterns during resting breathing are reliably tracked through computational fluid dynamics-based steady-state laminar viscous modeling, and such regimes portray relative lack of sensitivity to inlet perturbations. Consequently, we hypothesized that the posterior airflow transport and the particle deposition trends should not be radically affected by the nozzle subtraction and vestibular dilation. The study involved 1 base model and 2 derived models; the latter 2 with nozzle contours (2 different orientations) subtracted from the dilated anterior segment of the left vestibule. We analyzed spray transport in the left maxillary sinus for multiple release conditions. Similar release points, localized on an approximately 2 mm * 4.5 mm contour, facilitated improved maxillary deposition in all 3 test cases. This suggests functional redundancy of nozzle insertion in a 3D numerical model for identifying the optimal spray release locations. PMID- 29172252 TI - Prospects on the evolutionary mitogenomics of plants: A case study on the olive family (Oleaceae). AB - The mitogenome is rarely used to reconstruct the evolutionary history of plants, contrary to nuclear and plastid markers. Here, we evaluate the usefulness of mitochondrial DNA for molecular evolutionary studies in Oleaceae, in which cases of cytoplasmic male sterility (CMS) and of potentially contrasted organelle inheritance are known. We compare the diversity and the evolution of mitochondrial and chloroplast genomes by focusing on the olive complex and related genera. Using high-throughput techniques, we reconstructed complete mitogenomes (ca. 0.7 Mb) and plastomes (ca. 156 kb) for six olive accessions and one Chionanthus. A highly variable organization of mitogenomes was observed at the species level. In olive, two specific chimeric genes were identified in the mitogenome of lineage E3 and may be involved in CMS. Plastid-derived regions (mtpt) were observed in all reconstructed mitogenomes. Through phylogenetic reconstruction, we demonstrate that multiple integrations of mtpt regions have occurred in Oleaceae, but mtpt regions shared by all members of the olive complex derive from a common ancestor. We then assembled 52 conserved mitochondrial gene regions and complete plastomes of ten additional accessions belonging to tribes Oleeae, Fontanesieae and Forsythieae. Phylogenetic congruence between topologies based on mitochondrial regions and plastomes suggests a strong disequilibrium linkage between both organellar genomes. Finally, while phylogenetic reconstruction based on plastomes fails to resolve the evolutionary history of maternal olive lineages in the Mediterranean area, their phylogenetic relationships were successfully resolved with complete mitogenomes. Overall, our study demonstrates the great potential of using mitochondrial DNA in plant phylogeographic and metagenomic studies. PMID- 29172253 TI - Transcriptome profiling of sorted endoreduplicated nuclei from tomato fruits: how the global shift in expression ascribed to DNA ploidy influences RNA-Seq data normalization and interpretation. AB - As part of normal development most eukaryotic organisms, ranging from insects and mammals to plants, display variations in nuclear ploidy levels resulting from somatic endopolyploidy. Endoreduplication is the major source of endopolyploidy in higher plants. Endoreduplication is a remarkable characteristic of the fleshy pericarp tissue of developing tomato fruits, where it establishes a highly integrated cellular system that acts as a morphogenetic factor supporting cell growth. However, the functional significance of endoreduplication is not fully understood. Although endoreduplication is thought to increase metabolic activity due to a global increase in transcription, the issue of gene-specific ploidy regulated transcription remains open. To investigate the influence of endoreduplication on transcription in tomato fruit, we tested the feasibility of a RNA sequencing (RNA-Seq) approach using total nuclear RNA extracted from purified populations of flow cytometry-sorted nuclei based on their DNA content. Here we show that cell-based approaches to the study of RNA-Seq profiles need to take into account the putative global shift in expression between samples for correct analysis and interpretation of the data. From ploidy-specific expression profiles we found that the activity of cells inside the pericarp is related both to the ploidy level and their tissue location. PMID- 29172254 TI - The role of nonsteroidal anti-inflammatory drugs intramuscular injection in the development and severity of deep soft tissue infection in mice. AB - The aim of this study was to determine the role of nonsteroidal anti-inflammatory drugs (NSAID) injection on the severity of local infection and the effect on the progression of soft tissue infection (STI).The mouse model of STI with Group A streptococcus (GAS) was developed and treated with diclofenac sodium (DS) intramuscularly. Mice were divided into five groups: administered DS for 48 h before GAS (Group 1), GAS-DS and maintained DS for 48 h (Group 2), DS for 48 h (Group 3), GAS on zero time (Group 4), and control (Group 5). In vitro, a high concentration (40 mg/L) of DS inhibited GAS growth, whereas a lower concentration (0.4 mg/L) was not effective. Sepsis was observed in animals with DS and GAS inoculation (group 1 and 2). Group 4 had statistically significant higher bacterial load than groups 1 and 2. All groups had a higher inflammation rate than the control group. The median of TNF-alpha and mean IL-6 in the groups 1, 2, and 4 was significantly higher than those in the control group. Even if the animals that were treated with DS injection prior to the GAS inoculation had similar inflammation score, similar cytokine levels and low bacterial load in the tissue, they had a rather high rate of sepsis. In conclusion, DS injection prior to bacterial inoculation might predispose to bacteremia and sepsis. PMID- 29172255 TI - Relationship between deterioration of glycated hemoglobin-lowering effects in dipeptidyl peptidase-4 inhibitor monotherapy and dietary habits: Retrospective analysis of Japanese individuals with type 2 diabetes. AB - The present study was designed to assess possible relationships between deterioration of the glycated hemoglobin (HbA1c)-lowering effects in dipeptidyl peptidase-4 inhibitor (DPP4i) monotherapy and macronutrient intake among individuals with type 2 diabetes. Type 2 diabetes patients who began and continued DPP4i monotherapy without any prescription change for 1 year were retrospectively stratified into two groups: (i) patients who maintained their HbA1c levels during the 0.5- to 1-year period after DPP4i initiation (group A, DeltaHbA1c [1-0.5 year] <0.4%, n = 53); and (ii) those whose HbA1c levels increased [group B, DeltaHbA1c (1-0.5 year] >=0.4%, n = 10). Group B had significantly higher DeltaHbA1c (1-0.5 year), Deltabodyweight (1-0.5 year) and fat intake, especially of saturated and monounsaturated fats; the carbohydrate and protein intake were similar between groups. Multiple regression analyses showed that fat intake, especially saturated fat intake, was significantly correlated with DeltaHbA1c (1-0.5 year). Thus, dietary habits, especially saturated fat intake, might well contribute to deterioration of the HbA1c lowering effects in DPP4i monotherapy. PMID- 29172256 TI - UICC-ARO Symposium at the UICC 2016 World Cancer CongressHow Can We Mobilize Action to Realize UHC in Asia? AB - The 2016 World Cancer Congress, organised by UICC, was held in Paris in November 2016, under the theme "Mobilizing action - Inspiring Change." As part of Track 4 presentations on the theme of "Strengthening cancer control: optimizing outcomes of health systems," UICC-Asian Regional Office (UICC-ARO) held a symposium to discuss the issue of mobilizing action to realize UHC in Asia. Introducing the symposium, Hideyuki Akaza noted that universal health coverage (UHC) is included in the Sustainable Development Goals and one of the key issues for achieving UHC will be how to balance patient needs with the economic burden of cancer. Speakers from Japan and Indonesia addressed various issues, including the current status and challenges for medical economic evaluation in Asia, the importance of resource stratification, prospects for precision medicine, and the outlook for cancer control and UHC in developing and emerging countries in Asia. Key issues raised included how to respond to the rising costs of treating cancer as new and increasingly expensive drugs come to the market. Speakers and participants noted that health technology assessment programs are being developed around Asia in order to evaluate the cost-effectiveness of drugs in the face of budgetary constraints within increasingly pressurized national health systems. The importance of screening and early detection was also noted as effective means that have the potential to reduce reliance on expensive drugs for advanced cancers. The symposium was chaired jointly by Hideyuki Akaza and Shinjiro Nozaki (WHO Kobe Centre). PMID- 29172257 TI - Clinicopathological Significance of MTA 1 Expression in Patients with Non-Small Cell Lung Cancer: A Meta-Analysis AB - Background: Metastasis associated gene 1(MTA1) is one of the most deregulated molecules in human cancer andleads to cancer progression and metastasis. We performed a meta-analysis to determine the correlations between MTA1expression and the clinicopathological characteristics of non-small cell lung cancer (NSCLC). Methods: We searchedPubMed, Springer, Science Direct, Google Scholar and China National Knowledge Infrastructure (CNKI) for relevantarticles. For statistical analyses, we used R3.1.1 software. The fixed or random effects model was employed based onthe results of the statistical test for homogeneity. Results: Seven studies involving 660 NSCLC patients were included.The proportion of MTA1 overexpression with 95% confidence interval (95% CI) was 0.53(95%CI: 0.43 0.62) in NSCLCpatients; 0.47(95%CI: 0.40-0.55) in age <60 years and 0.52(95%CI: 0.34-0.70) in age >=60 years; 0.5(95%CI: 0.41-0.62) in males and 0.51(95%CI: 0.39 0.62) in females; 0.59(95%CI: 0.48-0.69) in squamous cell carcinoma (SC) and0.57(95%CI: 0.46-0.67) in adenocarcinoma (AC); 0.39(95%CI: 0.23-0.56) in well differentiated tumors, 0.44(95%CI:0.37-0.51) in moderately differentiated tumors and 0.55(95%CI: 0.37-0.51) in poorly differentiated tumors; 0.48(95%CI:0.36-0.60) in clinical grade (III-IV) NSCLC and 0.75 (95%CI: 0.69-0.81) in clinical grade (I II) NSCLC; 0.58(95%CI:0.45-0.71) in T Stage (T1/T2) NSCLC; 0.68(95%CI: 0.49-0.82) in NSCLC patients with lymph node positivity and0.51(95%CI: 0.43-0.58) in NSCLC patients with lymph node negativity. Conclusions: These results indicated thatMTA1 might be a valuable biomarker in the diagnosis of NSCLC. MTA1 overexpression was significantly associatedwith age >=60 years, gender, histopathological type, clinical grade (I-II), T stage (T1/T2) and lymph node positivity inNSCLC patients. PMID- 29172258 TI - Dual Function of Gold Nanoparticles in Synergism with Mitoxantrone and Microwave Hyperthermia Against Melanoma Cells AB - Background: This study was performed to evaluate any synergetic effects of mitoxantrone (MX) and goldnanoparticles (GNPs) as dual therapeutic approach, along with microwave (MW) hyperthermia for melanomacancer. Methods: Various tests were performed on the DFW melanoma cell line in the presence of MX and differentconcentrations of GNPs, with and without MW irradiation. MTT [3-(4,5 dimethylthiazol-2-yl)-2,5-iphenyltetrazoliumbromide] assays were conducted to evaluate the effectiveness of the used therapeutic methods in terms of cell survival.Relative lethal synergism (RLS) was calculated as the ratio of cell death following hyperthermia in the presence of atreatment agent to that after applying hyperthermia in the absence of the same treatment agent. Results: Results showedMX and GNPs under MW irradiation to provide maximum cell death (P < 0.001 compared to the other groups). Themean RLS for MW hyperthermia along with the MX-GNP combination was 4.14, whereas in the absence of GNP thevalue for MX chemotherapy was 0.94. Conclusion: MX chemotherapy in the presence of different concentrations ofGNP did not alter cell survival as compared to in its absence. PMID- 29172259 TI - Anthocyanins from the Fruit of Vitis Coignetiae Pulliat Inhibit TNF-Augmented Cancer Proliferation, Migration, and Invasion in A549 Cells AB - Objective: Anthocyanins belong to a class of flavonoids, exhibiting antioxidant and anti-inflammatory actions havebeen reported to have anti-cancer effects. Here, we investigated whether anthocyanins can inhibit cancer cell proliferation,invasion, and angiogenesis in human lung cancer A549 cells, which are critically involved in cancer metastasis. Methods:We used anthocyanins from fruits of Vitis coignetiae Pulliat (AIMs) which has been used in Korean folk medicine forthe treatment of inflammatory diseases and cancers. We have performed cell proliferation assays, cell invasion assay,gelatin zymography, wound healing assay and western blotting to examine whether anthocyanins can inhibit cancercell proliferation, invasion, and angiogenesis in A549 cells. Result: AIMs did not inhibit cancer cell proliferation onA549 cells. Also, AIMs suppressed cancer migration, and invasion by supressing MMP-2 and MMP-9 expression.The Immuno blotting results also revealed that AIMs suppressed the proteins involved in cancer proliferation (COX-2, C-myc, cyclin D1), migration and invasion (MMP-2, MMP-9), anti-apoptosis (XIAP, and c-IAP2), adhesion andangiogenesis (ICAM-1, VEGF). Conclusion: This study demonstrates that the anthocyanins isolated from fruits ofVitis coignetiae Pulliat inhibit cancer proliferation, cancer migration, and invasion that is involve in cancer-metastasis.This study provides evidence that AIMs might have anti-cancer effects on human lung cancer. PMID- 29172260 TI - The Lys469glu/K469E Polymorphism of the Inflammatory Gene Intercellular Adhesion Molecule-1 Lacks any Apparent Role in the Polycystic Ovary Syndrome in Kashmiri Women: A Case Control Study AB - Background: Polycystic ovary syndrome (PCOS), associated with a state of low grade chronic inflammation,depends on multiple genetic and environmental factors. Elevated levels of inflammatory markers including intercellularadhesion molecule 1 (ICAM-1) have been demonstrated in affected women. Recent evidence indicates a significantlinkage between chromosome 19p13 loci and multifactorial diseases that have an inflammatory component. The aim ofthis study was to assess the possible association of the lys469glu (K469E) polymorphism of the ICAM-1 gene locatedon chromosome 19p13 with risk of PCOS in Kashmiri women. Material and Methods: The K469E single nucleotidepolymorphism (SNP) was analysed with DNA from peripheral blood leukocytes of 220 PCOS cases and 220 agematched non-PCOS healthy controls using PCR-RFLP. Results: Genotypic frequencies in cases were found to be 32(14.5%) for EE, 98 (44.5%) for KE, and 90 (40.9%) for KK, with 130 (59.1%) for the KE+EE genotypes comparedto healthy control values of 29 (13.2%) for EE, 113 (51.4%) for KE, 78 (35. 5%) for KK and 142 (64.5%) for KE+EEcombined.The odds ratios for the EE, KE and KE:EE genotypes were 0.95(95% CI= 0.53-1.71)[p= 0.88], 0.75(95%CI= 0.50-1.12)[p =0.168] and 0.79 (95% CI =0.53-1.16) [p = 0.23], no statistically significant differences being foundbetween cases and controls (chi2 =2.07; p=0.35). Conclusion: In conclusion, there was no apparent significant influenceof the K469E polymorphism on risk of PCOS, or any clinical or laboratory parameters. PMID- 29172261 TI - Knowledge of Evidence-Based Cancer Risk Factors Remains Low Among New Zealand Adults: Findings from Two Cross-Sectional Studies, 2001 and 2015 AB - Objective: Cancer risk reduction messages are a part of cancer control efforts around the world. The complex realityis that risk factors differ for different types of cancer, making clear communication of desired behavioural changes moredifficult. This study aims to describe awareness of risk factors for breast, bowel, cervical, prostate and lung cancer andcutaneous melanoma among New Zealanders in 2014/15 and identify changes in awareness since 2001. Methods: Twonational telephone surveys, the first (CAANZ01) conducted in 2001, included 438 adults (231 females and 207 males,64% response rate). The second, conducted in 2014/15 (CAANZ15), included 1064 adults (588 females and 476 males,64% response rate). Results: In 2014/5, most participants could identify evidence based risk factors for lung cancerand melanoma. In contrast, many participants were unable to name any risk factors (evidence-based or otherwise) forbowel (34.8%), breast (48.8%), cervical (53.9%) and prostate cancer (60.9%). Between 2001 and 2014/5 there wereincreases in the proportion of individuals identifying sunbeds as increasing melanoma risk, and alcohol consumption andfamily history as increasing risk for bowel and breast cancer. Conclusions: Effective communication of risk informationfor specific cancers remains a challenge for cancer control. Although some positive changes in awareness over the 14year period were observed, there remains substantial room for progressing awareness of evidence-based risk factors. PMID- 29172263 TI - Predicting Intention Perform Breast Self-Examination: Application of the Theory of Reasoned Action AB - Objective: The present study aimed to examine the applicability of the theory of reasoned action to explain intentionto perform breast self-examination (BSE). Methods: A questionnaire was constructed to collect data. The hypothesiswas tested in two steps. First, to assess the strength of the correlation among the constructs of theory of reasoned action(TRA), Pearson's product moment correlations were applied. Second, multivariate relationships among the constructswere examined by performing hierarchical multiple linear regression analysis. Result: The findings supported the TRAmodel, explaining 45.8% of the variance in the students' BSE intention, which was significantly correlated with attitude(r = 0.609, p = 0.000) and subjective norms (r = 0.420, p =0 .000). Conclusion: TRA could be a suitable model to predictBSE intentions . Participants who believed that doing BSE regularly is beneficial for early diagnosis of breast cancerand also believed that their significant referents think that doing BSE would significantly detect breast cancer earlier,were more likely to intend to perform BSE regularly. Therefore, the research findings supported the conclusion thatpromoting the importance of BSE at the community/social level would enhance individuals to perform BSE routinely. PMID- 29172262 TI - Modulatory Effects of Chemoradiation on Angiogenic Factors and Laminin in Cervical Cancer: Link with Treatment Response AB - Objective: Carcinoma of the uterine cervix is either the first or second most common malignancy in Indian women,depending on the registry. Tumor growth and metastasis primarily are determined by angiogenesis and parametersof the molecular environment including extracellular matrix elements, growth factors and cytokines. Effects ofchemo-irradiation on biomarkers like vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2) and lamininin patients with carcinoma cervix therefore need to be explored. Methods: Circulatory and mRNA levels of VEGF,Ang-2 and laminin in patients with stage III carcinoma cervix (n=40) were compared with those of normal healthywomen (n=20). Measurement was prior to treatment, and after chemotherapy and teleradiation, using high sensitivityELISA kits and Q-PCR. Clinical response was evaluated as per WHO criteria and was assessed for correlation with thebiochemical markers. Results: Levels of all the studied molecules were significantly (p<0.001) higher in patients than incontrols. After treatment significant decline (p<0.001) was noted. Out of 40 patients, 33 were complete responders and7 were non-responders on clinical assessment. On comparison of before and after treatment levels of these moleculescomplete responders showed significant decline whereas non responders showed non-significant decrease. Follow-upof the responders for 3 years, revealed 28 of 33 patients to still be disease free, the other 5 demonstrating recurrence.Conclusions: Higher levels of angiogenic factors along with laminin indicate roles played in disease progression aidingangiogenesis. These markers may serve as useful tools in post treatment disease mapping, for which available imagingmethods may not provide a true picture. PMID- 29172264 TI - Different Sources of Dignity-Related Distress in Women Receiving Chemotherapy for Breast Cancer AB - Background: Identification of different sources of dignity-related distress experienced by people nearing the end oflife may help nurses to provide better care services. This study was conducted to determine sources of dignity relateddistress from the perspective of women with breast cancer undergoing chemotherapy. Materials and Methods: Inthis cross sectional study, the participants comprised 207 women with breast cancer undergoing chemotherapy inchemotherapy clinics in hospitals of Tehran, Iran. The Cronbach's coefficient alpha for the PDI was 0.76. Validityof PDI by confirmatory factor analysis shows that the comparative Fit Index of this instrument is 0.96 and so it isappropriate for application in different setting. Data were analyzed by Stata version 13. Results: Patients were mostlyconcerned about the distress caused by disease symptoms (mean; 2.4061, S.D.; 0.96), followed by existential distress(mean; 1.8784, S.D.; 0.75), peace of mind (mean; 1.871, S.D.; 0.77), dependence (mean; 1.8647, S.D.; 0.98), andsocial support (mean; 1.4097, S.D.; 0.99), respectively, in order of highest scores. Conclusion: Considering that thepatients were mostly concerned about the distress caused by disease symptoms, followed by existential distress, peaceof mind, dependency, and social support, it seems necessary to take further measures toward addressing these issues. PMID- 29172265 TI - SNPs in the Insulin-Like Growth Factor Gene and Obesity Impact on Colorectal Cancer in Egyptians AB - Background and aims: The insulin pathway may play a role in development of colorectal cancer (CRC). Inthis study, we investigated associations between CRC and obesity in Egyptians with reference to single nucleotidepolymorphisms (SNPs) in the insulin-like growth factor-1 (IGF-I) gene. We also studied serum levels of IGF-1inEgyptian CRC patients with different BMI values. Methods: This prospective study included 66 CRC patients and30 healthy individuals, for whom body mass index (BMI) was estimated, patients and controls being categorized intooverweight or obese in one group and average weight in the other. Serum levels of IGF-1 were assessed by ELISA andSNPs in the IGF-I gene at rs6214C/T, rs6220 T/C and rs35767 C/T were examined by PCR- RFLP. Results: Serumlevels of IGF-1 were significantly lower in both CRC average weight and overweight cases. IGF-1 could negativelypredict CRC at a cut-off of 154 ng/ml with 87.5% sensitivity and 72.6 specificity. IGF-1 rs6214 CT and TT (T allele)genotypes were associated with a significantly increased risk of CRC. Univariate logistic regression showed that CRCrisk significantly decreases by 0.14 for each one unit increase in IGF1. Conclusion: BMI could be considered as effectmodifier for CRC risk. IGF-1 SNP rs6214 (TT and CT) are significantly associated with risk regardless of the BMI. PMID- 29172266 TI - Dosimetric Validation of Volumetric Modulated Arc Therapy (VMAT) Using AAPM TG 119 Benchmark Plans in an Upgraded CLINAC 2100CD for Flattening Filter Free (FFF) Photon Beams AB - Background: Recently we have upgraded our Varian Clinac 2100CD with a 6MV FFF beam, this upgrade beingthe first of its kind in our country. Even though the dosimetric characteristics of FFF beams have been reported both inexperimental and Monte Carlo studies, application in planning and delivery is complex. The aim of this study was tovalidate the commissioning of upgraded FFF beams dosimetrically using AAPM TG-119 bench mark plans for VMATand to make a comparison with IMRT plans for both flattened filtered and FFF beams. Materials and Methods: AAPMTG-119 proposes a set of test clinical cases for testing the accuracy of IMRT planning and delivery systems. For theseclinical cases we generated four treatment plans using IMRT FF, IMRT FFF, VMAT FF and VMAT FFF on a VarianClinac 2100CD machine equipped with a millennium 120 MLC in Eclipse treatment planning system. Dose prescriptionand planning objectives were set according to the TG-119 goals and plans were scored based on planning objectives.Plans were compared using dose coverage, the conformity index and the homogeneity index. Point doses were measuredat points recommended by TG-119 using a CC13 ion chamber. Planar dosimetry was accomplished using Imatrix andgamma evaluation was conducted using Omnipro IMRT software. Results: Dose distributions of FFF beam basedplans were comparable to FF plans for both IMRT and VMAT. Our planning results matched TG-119 planning results.Measured point doses were within +/-2% of planned doses and planar dosimetry gamma values were <1 for >95% ofdata points for all plans. Conclusion: We found a reduction of 40% treatment time for FFF against FF beams for slidingwindow IMRT. Upgraded FFF beams were in good agreement with TG-119 benchmark plans and goals. PMID- 29172267 TI - Breast Cancer Risk Assessment Using the Gail Model and It's Predictors in Saudi Women AB - Background: The Gail Model has been widely implemented in developed and developing countries and is consideredto be the best available instrument to estimate breast cancer (BC) risk for early prevention. Objective: The goals ofthe study were to determine five-year and lifetime BC risks and to assess BC predictors among female Saudi teachersusing the Gail model. Methods: A cross sectional study with convenience sampling was conducted among 180 femaleSaudi secondary school teachers. The Gail model was used to evaluate the five-year and lifetime risks of developingBC. Included were a one-day 24-hour recall to assess daily serving sizes and food groups for food intake and questionsregarding daily exercise, BMI, and demographic data. Result: The mean age of the teachers was 41+/-7.2 years, witha 0.87+/-0.93 mean for the five-year risk and a 9.6+/-5.4 mean lifetime risk of developing BC. According to the generallinear model, the BC risk predictors were age, age at menarche, age at first pregnancy, family history, BMI, fruit andvegetable intake, and meat intake. Conclusion: The present study provided new information regarding the potentialfactors for five-year and lifetime invasive BC risk among Saudi women. Moreover, we could confirm that the Gailmodel is an appropriate BC risk assessment tool for Saudi women for early prevention, particularly among women athigh risk of BC. PMID- 29172268 TI - Effect of Targeted Therapy With Pazopanib on Expression Levels of Transcription, Growth Factors and Components of AKT/m-TOR Signaling Pathway in Patients with Renal Cell Carcinoma AB - Background: The effect of the targeted therapy on cancer molecular markers remains currently unknown. Theaim of the study was to investigate the expression and content of transcription, growth factors and components of theAKT/m-TOR signaling pathway in kidney cancer patients before and after targeted therapy with pazopanib. Methods:A total of 157 patients with renal cell carcinoma were enrolled into the study. The level of mRNA expression wasinvestigated by real time PCR, and the contents of transcription and growth factors, as well as the levels of AKT/m-TOR signaling pathway components were determined by ELISA and Western blotting. Results: Targeted therapy withpazopanib resulted in a 3.1-fold decrease in HIF-2alpha expression that was accompanied by a reduction in the levels ofNF-kappaB p65 and p50, HIF-1alpha and CAIX. The levels of GSK-3beta and AKT mRNA were increased; however, the levelsof corresponding proteins remained low. The targeted therapy with pazopanib did not influence the level of PTENphosphatase. A 1.9-fold increase in the level of p70 S6 (S371) was observed after therapy. Conclusion: The efficacy oftyrosine kinase inhibitors is associated with the changes in the angiogenic factors. Molecular characteristics of cancercould determine markers of disease progression as well as potential targets for anticancer therapies PMID- 29172269 TI - Positive Impact of Social Media Use on Depression in Cancer Patients AB - Objective: The focus of attention was the prevalence of depression among cancer patients using social networks.An attempt was made to determine if social media could help cancer patients overcome their stress and depression,causes of serious emotional and mental problems for them and their families. Methods: To ascertain the prevalenceof depression among cancer patients with reference to use of social networks, 316 cancer patients in the Associationof Cancer Patients and cancer related centers in Tehran at 2015 were evaluated. Depression was measured using theBeck Depression Inventory. Data were analyzed by the Chi-square test with SPSS software. Results: Using the Beckcriteria, 61% (N=192) of patients were depressed. Interestingly, a significant difference was observed between depressionin users and non-users of social networks (p=0.001), 33.9% and 66.1% being affected, respectively. Conclusion:These results verified a high incidence of depression in cancer patients, but a beneficial effect of social network use.Therefore access to social networks should be promoted for prevention and amelioration of depression. Moreover, itis recommended that particular attention be paid to the patient sex and educational level in designing counseling andpsychological skill training programs. PMID- 29172270 TI - 18-Fluorodeoxy-Glucose Positron Emission Tomography- Computed Tomography (18-FDG PET/CT) for Gross Tumor Volume (GTV) Delineation in Gastric Cancer Radiotherapy AB - Purpose: Evaluation of the 18-fluorodeoxy-glucose positron emission tomography computed tomography (18-FDGPET/CT) for gross tumor volume (GTV) delineation in gastric cancer patients undergoing radiotherapy. Methods: In thisstudy, 29 gastric cancer patients (17 unresectable and 7 inoperable) were initially enrolled for radical chemoradiotherapy(45Gy/25 fractions + chemotherapy based on 5 fluorouracil) or radiotherapy alone (45Gy/25 fractions) with planningbased on the 18-FDG-PET/CT images. Five patients were excluded due to excess blood glucose levels (1), false-negativepositron emission tomography (1) and distant metastases revealed by 18-FDG-PET/CT (3). The analysis involvedmeasurement of metabolic tumor volumes (MTVs) performed on PET/CT workstations. Different threshold levels ofthe standardized uptake value (SUV) and liver uptake were set to obtain MTVs. Secondly, GTVPET values were derivedmanually using the positron emission tomography (PET) dataset blinded to the computed tomography (CT) data.Subsequently, GTVCT values were delineated using a radiotherapy planning system based on the CT scans blinded tothe PET data. The referenced GTVCT values were correlated with the GTVPET and were compared with a conformalityindex (CI). Results: The mean CI was 0.52 (range, 0.12-0.85). In 13/24 patients (54%), the GTVPET was larger thanGTVCT, and in the remainder, GTVPET was smaller. Moreover, the cranio-caudal diameter of GTVPET in 16 cases(64%) was larger than that of GTVCT, smaller in 7 cases (29%), and unchanged in one case. Manual PET delineation(GTVPET) achieved the best correlation with GTVCT (Pearson correlation = 0.76, p <0.0001). Among the analyzedMTVs, a statistically significant correlation with GTVCT was revealed for MTV10%SUVmax (r = 0.63; p = 0.0014), MTVliv(r = 0.60; p = 0.0021), MTVSUV2.5 (r = 0.54; p = 0.0063); MTV20%SUVmax (r = 0.44; p = 0.0344); MTV30%SUVmax (r = 0.44;p = 0.0373). Conclusion: 18-FDG-PET/CT in gastric cancer radiotherapy planning may affect the GTV delineation. PMID- 29172271 TI - Association between ERCC1 Polymorphism and the Risk and Clinicopathological Features of Breast Cancer in Thai Women in the Lower Northeastern Region AB - Background: Breast cancer is a major public health problem around the world, including Thailand and it hasthe highest ranking among female cancer. Currently, the diversity or polymorphism of ERCC1 gene (excision repaircross-complementary group 1 gene or ERCC1) was reported to associate with an increased risk of breast cancer.This study aims to investigate the relationship between ERCC1 polymorphism and the breast cancer risk in the lowernortheastern region women of Thailand. Materials and Methods: One hundred fifty one samples from breast cancerpatients and 120 samples from healthy control group were analysed. Genomic DNA was extracted from white bloodcell of all samples. The real-time polymerase chain reaction (qPCR) was used to demonstrate genetic polymorphismof ERCC1. Results: The results showed that the ERCC1 rs11615 polymorphism variant AG was associated with anincreased risk of breast cancer. This study demonstrated that the frequency of ERCC1 rs11615 in patients with breastcancer was higher than healthy control group. The ERCC1 polymorphism variant AG carrier presented 3.53-folds highrisk of breast cancer [odds ratio (OR) = 3.53, 95% CI = 1.61-7.74, P = 0.001]. In addition, when age, menopause period,number of child, smoking and alcohol drinking were adjusted, the ERCC1 rs11615 variant AG carrier was associatedwith increased breast cancer risk to 3.97 folds, with OR = 3.79, 95% CI = 1.62-8.84, P = 0.002. Conclusions: Thisstudy showed that ERCC1 rs11615 genotype AG was associated with breast cancer risk in the lower northeasternregion women of Thailand. PMID- 29172272 TI - Promoter Hypermethylation of the ATM Gene as a Novel Biomarker for Breast Cancer AB - Background: Breast cancer may be induced by activation of protooncogenes to oncogenes and in many casesinactivation of tumor suppressor genes. Ataxia telangiectasia mutated (ATM) is an important tumor suppressor genewhich plays central roles in the maintenance of genomic integrity by activating cell cycle checkpoints and promotingrepair of double-strand breaks of DNA. In breast cancer, decrease ATM expression correlates with a poor outcome;however, the molecular mechanisms underlying downregulation are still unclear. Promoter hypermethylation maycontribute in downregulation. Hence the present investigation was designed to evaluate promoter methylation andexpression of the ATM gene in breast cancer cases, and to determine links with clinical and demographic manifestations,in a South Indian population. Methods: Tumor biopsy samples were collected from 50 pathologically confirmedsporadic breast cancer cases. DNA was isolated from tumor and adjacent non-tumorous regions, and sodium bisulfiteconversion and methylation specific PCR were performed using MS-PCR primers for the ATM promoter region. Inaddition, ATM mRNA expression was also analyzed for all samples using real-time PCR. Results: Fifty eight percent(58%) of cancer tissue samples showed promoter hypermethylation for the ATM gene, in contrast to only 4.44% ofnormal tissues (p= 0.0001). Furthermore, ATM promoter methylation was positively associated with age (p = 0.01),tumor size (p=0.045) and advanced stage of disease i.e. stages III and IV (p =0.019). An association between promoterhypermethylation and lower expression of ATM mRNA was also found (p=0.035). Conclusion: We report for thefirst time that promoter hypermethylation of ATM gene may be useful as a potential new biomarker for breast cancer,especially in the relatively young patients. PMID- 29172273 TI - Sonographic Diagnosis of Tubal Cancer with IOTA Simple Rules Plus Pattern Recognition AB - Objective: To evaluate diagnostic performance of IOTA simple rules plus pattern recognition in predicting tubalcancer. Methods: Secondary analysis was performed on prospective database of our IOTA project. The patientsrecruited in the project were those who were scheduled for pelvic surgery due to adnexal masses. The patients underwentultrasound examinations within 24 hours before surgery. On ultrasound examination, the masses were evaluated usingthe well-established IOTA simple rules plus pattern recognition (sausage-shaped appearance, incomplete septum,visible ipsilateral ovaries) to predict tubal cancer. The gold standard diagnosis was based on histological findings oroperative findings. Results: A total of 482 patients, including 15 cases of tubal cancer, were evaluated by ultrasoundpreoperatively. The IOTA simple rules plus pattern recognition gave a sensitivity of 86.7% (13 in 15) and specificityof 97.4%. Sausage-shaped appearance was identified in nearly all cases (14 in 15). Incomplete septa and normalovaries could be identified in 33.3% and 40%, respectively. Conclusion: IOTA simple rules plus pattern recognitionis relatively effective in predicting tubal cancer. Thus, we propose the simple scheme in diagnosis of tubal cancer asfollows. First of all, the adnexal masses are evaluated with IOTA simple rules. If the B-rules could be applied, tubalcancer is reliably excluded. If the M-rules could be applied or the result is inconclusive, careful delineation of the masswith pattern recognition should be performed. PMID- 29172274 TI - Delay in Diagnosis and Treatment of Breast Cancer among Women Attending a Reference Service in Brazil AB - Background: Cancer is a major public health problem. Early diagnosis and treatment are essential for reducingmortality. This study aimed to analyze factors associated with delay in breast cancer diagnosis and treatment amongwomen attending a reference cancer service. Methods: This retrospective, cross sectional study was performed withdata collected from medical records and interviews conducted with women diagnosed with breast cancer and treatedfrom October 2013 to October 2014 at a cancer reference hospital in Parana, Southern Brazil. Results: A total of 82participants were enrolled during the study period; their average age was 58.2 +/- 11.5 years. The average time takenfor final diagnosis of breast cancer was 102.5 +/- 165.5 days. Treatment onset was delayed in the majority of cases, andthe average time elapsing from diagnostic biopsy to onset of primary treatment was 72.3 +/- 54.0 days. The odds oftreatment delay were higher among the women with a low educational level. Conclusions: The results underline theneed for proposals aimed at early detection, identification of risk factors and timely provision of treatment by healthmanagers that focus on this group. PMID- 29172275 TI - Interleukin-6 Genetic Variation and Susceptibility to Gastric Cancer in an Iranian Population AB - Background: Despite recent decrease in the incidence of gastric cancer, it is still a common type of cancer in thenorth of Iran. Many evaluations have shown that polymorphisms of cytokine genes like that for interleukin 6 (IL-6),which play important roles in regulation of the immune response, can increase the risk of gastric cancer. This studyexamined the role of the IL-6-174 gene polymorphism in susceptibility in an Iranian population. Method: GenomicDNA was extracted from peripheral whole blood of 100 patients and 361 healthy controls. Genotyping was accomplishedby the sequence-specific primer-polymerase chain reaction (SSP-PCR) method and statistical analyses were carriedout using Fisher's exact test. Frequencies of the IL-6-174 G/C genotypes were determined under co dominant,dominant, and recessive genetic models. Results: An association between the polymorphism of IL-6 -174 G/C andsusceptibility to gastric cancer was observed. The frequency of G allele was higher in patients (78%) than in controls(70.5 %) (OR=1.48, 95% CI=1.01-2.20, P=0.04). Conclusions: The high G allele and G/G genotype frequency inpatients compared to control subjects suggests that the IL-6 -174 G/C polymorphism may influence the susceptibilityto gastric cancer. In addition, the demographic information showed that most of the subjects were male (69.0%) thatgastric cancer is related to environmental factors.

The frequency and types of gene mutations in these cases may differ among various populations.The objective of this study was to identify frequencies and types of FLT3-ITD, NPM1, and DNMT3A mutations, andassociations of them with clinical data and risk factors in CN-AML and CN-MDS cases in upper Northern Thailand.Methods: Bone marrow samples of 40 CN-AML and 60 CN-MDS patients were analyzed for gene mutations bydirect sequencing. In addition, data for potential risk factors were obtained for comparison. Results: Frequencies ofFLT3-ITD, NPM1, and DNMT3A mutations were 25.0%, 17.5%, and 10.0%, respectively in CN-AML, but all zero inCN-MDS cases. NPM1 mutations were found at a median age older than the wild type (58 vs 47 years) while DNMT3Amutations were associated with an increase in the white blood cell count. In all patients, factors for the mutations ofthese three genes included age <= 60 years, and a history of hypertension. Conclusion: When considering mutations inonly normal karyotype patients, the frequency of FLT3-ITD, NPM1, DNMT3A mutations in CN-AML patients in upperNorthern Thailand were found to occur at lower rates than in Western patients and to differ from other Asian populationsincluding parts of Thailand. No mutations were observed in CN-MDS cases. Some types of gene mutations differed fromprevious studies, possibly attributable to differences in geography, lifestyle and genetic backgrounds. Links with age <=60 years and history of hypertension were found. Investigation of these three genes in an intermediate risk group witha normal karyotype is useful for a better understanding of molecular leukemogenetic steps in CN-AML and CN-MDSpatients and may be beneficial for planning treatment and prevention in the population of upper Northern Thailand.

Methods: Expression of MCM2, MCM5 and 6 proteins in sputumsamples and corresponding tissues was assessed by immunocytochemistry, and correlated with histological findings.Results: For characterization of malignant, metaplastic or dysplastic cells, CDC6 protein had the highest sensitivityof 87.7%. All the three markers together had a sensitivity of 94.4%. Furthermore these proteins could be employed toassess the proliferative potential of precancerous or atypical cells, as overexpression increasing with the stage of diseaseand degree of metastasis. Conclusion: The assessed markers can be utilized in routine cytopathology laboratoriesto supplement conventional morphological evaluation so that the sensitivity of sputum cytology can be enhanced.Potential applications in predicting the clinical behavior of lung lesions and predicting prognosis and survival deservefurther attention. PMID- 29172278 TI - P16ink4a Subcellular Expression Patterns in Colorectal Adenocarcinoma, Adenoma and Non-Neoplastic Tissue Samples AB - Background: Colorectal cancer (CRC) is one of the most common neoplasms with high mortality at advancedstages worldwide. Thus diagnosis of CRC at an early stage with sensitive molecular methods is a high priority. Theaim of this study was to evaluate P16ink4a subcellular expression patterns in colorectal adenocarcinoma, adenoma andnon-neoplastic tissue samples. Methods: A total of 137 colorectal formalin fixed paraffin-embedded tissue blocksfrom the pathology archives of Ali Ebne-Abitaleb central hospital, Zahedan, Iran, were examined in three groups:adenocarcinoma (n= 63), adenoma (n= 38) and non-neoplastic (n= 36). The subcellular expression pattern wasdetermined by immunocytochemistry. Data analysis was performed using Kruskal-Wallis and Fisher exact tests withthe significance level set as p?0.05. Results: P16ink4a subcellular localization was observed in three different patterns,nuclear+cytoplasmic (73.33%), cytoplasmic (13.33%) and nuclear (13.33%). In most samples, nuclear+cytoplasmicwas the predominant subcellular pattern. However, a significant difference in P16ink4a subcellular expression patternswas observed along the non-neoplastic, adenoma, adenocarcinoma sequence (p?0.001). An association with thehistological tumor type was also noted (p=0.021). Conclusion: Considering variation in localization of P16ink4a underdifferent pathological conditions, P16ink4a night be sensitive prognostic biomarker for benign colon lesions. Its use mayimprove strategies for screening, prognostic assessment and management of patients with CRC. Further studies arerecommended in this field. PMID- 29172279 TI - Anti-Vascular Endothelial Growth Factor Targeting by Curcumin and Thalidomide in Acute Myeloid Leukemia Cells AB - Acute myeloid leukemias (AMLs) are blood disorders that exhibit uncontrolled growth and reduction of apoptosisrates. As with other malignancies, progression may be result of induction and formation of new blood vessels influencedby disease conditions. Cancer cells produce a variety of factors which play important roles in angiogenesis. Vascularendothelial growth factor (VEGF) is critical for many malignancies, including AMLs. Curcumin, as a natural compound,is able to enhance apoptosis via a mechanism affecting regulatory genes. As a new strategy we here evaluated anti-VEGF properties of curcumin, alone and in combination with thalidomide, in leukemic cell lines. Growth inhibitoryeffects were assessed by MTT assay and apoptosis was detected by annexin/PI staining in U937 and KG-1 cell lines.mRNA expression levels of VEGF isoforms were evaluated by qRT-PCR. Curcumin inhibited proliferation and inducedapoptosis in both KG-1 and U937 cells and this effect was stronger in combination with thalidomide. In KG-1 cells, thelevel of VEGF (A, B, C and D) mRNA was decreased in curcumin treated as compared to untreated cells. Maximumeffects were obtained at the concentration of 40 MUM curcumin in U937 cells. Taken together, the results indicate thatthe VEGF autocrine loop may have an impact on AML development and progression and could be considered as atherapeutic target. Thalidomide as a VEGF inhibitor in combination with curcumin appears to have a synergistic impacton inhibition of cell proliferation and promotion of apoptosis. PMID- 29172280 TI - Relationships of Ex-Vivo Drug Resistance Assay and Cytokine Production with Clinicopathological Features in the Primary Cell Culture of Thai Ovarian and Fallopian Tube Cancer Patients AB - Objective: Our goal was to determine the ex-vivo drug resistance assay, as well as the cytokine production, inresponse to platinum-based chemotherapy treatment in primary culture cells established from the tumor tissue of ovarianor fallopian tube carcinoma patients, and to predict the clinical responses to chemotherapy. Methods: Sensitivity tothe platinum-based drug was analyzed in two ovarian cancer cell lines and 19 tumor samples using the primary cellculture obtained from 19 patients having ovarian or fallopian tube cancer that had undergone surgery from 2014 to 2017.Results: Our findings in the ovarian cancer cell lines showed that SKOV3 cells displayed 10-fold greater resistanceto cisplatin and 5.8 times more resistance to carboplatin than A2780 cells. SKOV3 cells displayed platinum inducedIL-6 and IL-8 overproduction whereas wild type A2780 displayed no detectable cytokine production. Regarding theprimary cell culture obtained from patients, ex-vivo drug resistance assay results revealed that although extreme drugresistance was correlated with late stage ovarian cancer (P= 0.031), it could not independently predict or alter theoutcomes of patients with ovarian or fallopian tube cancer. No relationship was found between basal cytokine secretionand the clinical parameters. However, carboplatin-induced IL-6 and IL-8 production had a significant association withthe clinical response to chemotherapy (P=0.016 and P=0.038 respectively). Carboplatin-induced IL-8 overproductionwas correlated with FIGO staging III-IV (P=0.026), but no correlation between carboplatin-induced IL-6 and FIGOstaging (P= 0.061) was noted. Conclusion: These results suggest that cytokine production in response to platinum-basedchemotherapy in primary culture cells may be useful as a predictive marker for the therapeutic outcomes among ovarianor fallopian tube cancer patients. PMID- 29172281 TI - SNP rs16969968 as a Strong Predictor of Nicotine Dependence and Lung Cancer Risk in a North Indian Population AB - Background: The 15q24-25 loci contain genes (CHRNA5 and CHRNA3) encoding nicotinic acetylcholine receptorsubunits. We here determined for the first time the association of genetic variants rs16969968 and rs3743074 inCHRNA5 and CHRNA3, respectively, on nicotine dependence and lung cancer risk in a North Indian population by acase-control approach. Methods: Venous blood samples were obtained from 324 participants (108 lung cancer patientsand 216 healthy individuals). DNA was extracted and PCR amplified with primers flanking the SNPs rs16969968 andrs3743074. Amplicons were subjected to sequencing and logistic regression was used to analyze association betweenvariables. Results: The risk variant SNP rs16969968 in both heterozygous and homozygous forms appeared to exerta significant effect on nicotine dependence [GA (OR=2.77) and AA (OR=2.53)]. As expected, smoking was stronglyassociated with lung cancer (OR= 2.62). Risk allele rs16969968 in CHRNA5 also showed a significant association withincreased lung cancer risk in our cohort, alone (OR= 4.99) and with smoking as a co-variable (OR= 4.28). Comparisonof our analysis with other populations suggested that individuals with rs16969968 risk allele in the Indian populationare more susceptible to lung cancer. Conclusion: Overall, the results strongly indicated that, in our cohort North Indianpopulation, the genetic variant rs16969968, but not rs3743074, is significantly associated with both nicotine dependenceand increased risk of lung cancer. While the results are significant, there is further need to increase the sample size andimprove precision of our risk prediction. PMID- 29172282 TI - Primary Locations of Malignant Melanoma Lesions Depending on Patients' Gender and Age AB - Introduction: Location of malignant melanoma lesions depends on environmental, genetic, sociological anddemographical factors. Available sources do not provide enough information on such dependencies in various populations.There is no data concerning the role of socio-demographic factors for the population of the Central and Eastern Europe.Aim: The aim of this work was to evaluate the anatomical location of the primary malignant melanoma lesion incorrelation to patients' gender and age. Material and methods: A retrospective analysis of medical documentationof 363 patients has been performed. The patients had been diagnosed with malignant melanoma and were undergoingtreatment in the years 2010 2014 in two Polish oncologic hospitals. The subject group consisted of 199 (55%) femalesand 164 (45%) males. The age varied between 19 - 90 years, with the median of 62 years. Results: In women, themelanoma lesions seem to appear more often in their lower extremities, while in case of men such lesions seem to bemore often on their torsos. In both cases, the difference was statistically significant (p<0.01 When the specific locationsare considered in women the lesions were more often located on their shins (p<0.01), whereas for men the lesions werelocated on their backs (p<0.01). It has been observed that there is dependency between lesion localization and age ofpatients. The lesions located on heads and necks were most common in older patients, and the lesions located in lowerextremities were most common in younger ones. Conclusion: Differences in location of malignant melanoma lesionsmay be due to either genetic or environmental reasons. It is often emphasized in literature that correlation between thesocio demographic factors and the process of oncogenesis requires intensive research. In our work, we have tried to fillthis gap for the population of Central and Eastern Europe to determine the exact epidemiology of this kind of cancer.This knowledge may be then used for developing cancer prevention methods specific to gender and age. PMID- 29172283 TI - Repair Index in Examination of Nuclear Changes in the Buccal Mucosa of Smokers: A Useful Method for Screening of Oral Cancer AB - Background: Smoking is one of the major risk factors for cancers, especially in the oral cavity. Nuclear changesoccur in the early stages of cancer. The aim of this study was therefore to investigate nuclear changes and calculate a"repair index" for the buccal mucosa of smokers. Material and Methods: This historical cohort study was conductedby selecting samples including smokers and non-smokers. In addition, the smoker group were divided into 2 subgroupswith a smoking history of >10 and <=10 years. Buccal mucosa smears were obtained and Papanicolaou staining wasemployed to detect nuclear changes. Micronuclei, karyorrhexis and karyolysis were assessed and eventually a repairindex was calculated. Statistical analysis was performed using the t-test. Results: In the 60 samples studied, differenceswere significant in smopkers vs. nonsmokers for micronuclei, (P=0.002) but not karyorrhexis or karyolysis. (P=0.789 andP=0.578, respectively). Also, the repair index demonstrated no statistically significant variation (P=0.107). Comparisonof the two subgroups of smokers demonstrated that the frequency of micronuclei in those with a history >10 years wassignificantly higher and the RI was significantly lower than with <=10 years (P=0.0001 and 0.04, respectively). Whilekaryorrhexis and karyolysis were also higher in the longer exposure individuals the differences were not significant(P=0.07 and 0.78, respectively). Conclusion: Among the nuclear changes investigated, micronuclei proved the morereliable indicator to assess the adverse effects of smoking on the oral mucosa, becoming prominent with increase insmoking history. In addition, while a "repair index" may have benefits for assessment of nuclear damage caused bysmoking, further research is necessary in this field. PMID- 29172284 TI - Inhibitory Effect of Aspirin on Cholangiocarcinoma Cells AB - Aspirin and other non-steroidal anti-inflammatory drugs reduce the risk of cancer due to their anti-proliferative andapoptotic effects, which are the important mechanisms for their anti-tumor activity. Here, the effect of aspirin on humancholangiocarcinoma cells (KKU-214) and the underlying mechanisms of its action were explored. Cell proliferationwas measured by sulforhodamine B (SRB) assay, while cell cycle distribution and apoptosis were determined by flowcytometry. Western blotting was used to explore protein expression underlying molecular mechanisms of anti-cancertreatment of aspirin. Aspirin reduced cell proliferation in a dose- and time-dependent manner, and altered the cellcycle phase distribution of KKU-214 cells by increasing the proportion of cells in the G0/G1 phase and reducing theproportion in the S and G2/M phases. Consistent with its effect on the cell cycle, aspirin also reduced the expressionof cyclin D1 and cyclin-dependent kinase 4 (Cdk-4), which are important for G0/G1 cell cycle progression. Treatmentwith aspirin led to increased induction of apoptosis in a dose-dependent manner. Further analysis of the mechanismunderlying the effect of this drug showed that aspirin induced the expression of the tumor-suppressor protein p53 whileinhibiting the anti-apoptotic protein B-cell lymphoma-2 (Bcl-2). Correspondingly, the activation of caspase-9 and -3was also increased. These findings suggest that aspirin causes cell cycle arrest and apoptosis, both of which couldcontribute to its anti-proliferative effect. PMID- 29172285 TI - Body Mass Index and Breast Cancer Risk among Thai Premenopausal Women: a Case Control Study AB - Background: Breast cancer (BC) is the leading malignancy in women with high incidence and mortality worldwide.Obesity is one of several established risk factors for chronic diseases including cancer. The objective of this researchwas to determine the association of body mass index (BMI) with BC among Thai premenopausal women (TPW).Materials and Methods: A case-control study was conducted among TPW attending the National Cancer Institute inBangkok, with 257 cases and 257 controls in 2013-2014. Cases and controls were matched by age (+/- 5 years), residentialarea and duration of attending. Data were collected with a questionnaire comprising 2 parts: part 1 socio-demographiccharacteristics, and part 2 health risk behavior and reproductive factors and BMI. The obtained data were analyzedusing descriptive and analytic statistics with a computerized statistical package. Results: The study participants weremainly 40-44 years old (60 %) with an average age of 39 years. The major type of BC was the invasive ductal carcinoma(91.8%). On univariate analysis, risk factors for BC among the TPW were family history of BC, history of benignbreast tumors, younger age at menarche, parity, miscarriage, contraceptive use, passive smoking, multivitamin use,and BMI (p<0.05). Multivariable conditional logistic regression analysis, controlling for possible confounding factors,revealed that a BMI 25-29.9 and >= 30 kg/m2 increased the risk of BC by a factor of 2.09 and 2.37 times, respectively(OR=2.09, 95%CI =1.09-3.97; OR=2.37, 95%CI =1.24-10.06). Conclusions: A surveillance system of obesity shouldbe conducted in cooperation with information regarding physical activities and weight control among TPW as anessential measure to reduce BC risk. PMID- 29172286 TI - Epitope Mapping of Human HER2 Specific Mouse Monoclonal Antibodies Using Recombinant Extracellular Subdomains AB - Background: Human epidermal growth factor receptor 2 (HER2) is overexpressed in several human malignanciesand numerous studies have indicated that it plays important roles in the development and maintenance of the malignantphenotype. Targeting of HER2 molecules with monoclonal antibodies (mAbs) is a promising therapeutic approach.However, anti-HER2 mAbs affect cancer cells differently, depending on the distinct epitopes which are the targets.Methods: Reactivity of a panel of 8 mouse anti-HER2 mAbs was investigated by ELISA and Western blotting usingdifferent subdomains of the extracellular domain (ECD) of HER2. All subdomains, including I, II, III, IV, I+II,III+IV and full HER2-ECD were constructed and expressed in CHO cells. Cross-reactivity of the mAbs with othermembers of the human HER family and Cynomolgus HER2 was also studied by ELISA. The mAbs were also testedby immunohistochemistry (IHC) using HER2 positive breast cancer tissues. Results: Our results demonstrated that 3out of 8 mAbs detected conformational epitopes (1T0, 2A8 and 1B5), while 5 mAbs identified linear epitopes (1F2,1H9, 4C7, 1H6 and 2A9). Three of the mAbs recognized subdomain I, one reacted with subdomain I+II, 2 recognizedeither subdomain III or IV and 2 recognized subdomain III+IV. However, none of our mAbs recognized the subdomainII alone. The mAbs displayed either inhibitory or stimulatory effects on HER2-overexpressing tumor cells and did notreact with other members of the human HER family. The pattern of IHC results implied better reactivity of the mAbsrecognizing linear epitopes. Conclusions: Our findings suggest that paired subdomains of HER2 are essential formapping of mAbs recognizing conformational epitopes. Moreover, there seems to be no association between subdomainspecificity and antitumor activity of our anti-HER2 mAbs. PMID- 29172287 TI - Polycystic Ovarian Morphology may be a Positive Prognostic Factor in Patients with Endometrial Cancer who Achieved Complete Remission after Fertility-Sparing Therapy with Progestin AB - Background: The most studied fertility-sparing therapy for endometrial cancer (EC) is oral progestin therapy.However, complete remission (CR) rate after progestin therapy is not enough ranging from 60 to 80 %, with highrecurrence rate. Clinical features that predict treatment efficacy and recurrence after progestin therapy have not yetbeen revealed in detail. The aim of this study was to investigate prognostic factors in patients with EC who achievedCR after medroxyprogesterone acetate (MPA) therapy. Methods: We retrospectively reviewed 35 EC patients treatedwith MPA at our institution between 2000 and 2016. Following confirmation of endometrioid adenocarcinoma G1,patients orally took 600 mg MPA daily for 26 weeks. Patients with CR periodically took oral contraceptives. Theassociation of recurrence-free survival (RFS) with several clinical features including age, body mass index (BMI),and polycystic ovarian morphology (PCOM) was analyzed. Results: Of 35 patients, 25 (71%) achieved CR, whereas10 (29%) underwent hysterectomy due to failure of MPA therapy. Eleven (44%) of 25 patients with CR successfullygave birth after MPA therapy, whereas 8 (32%) developed recurrence. On univariate analysis, PCOM was significantlyassociated with better recurrence-free survival (RFS) (P=0.009), and BMI >=25 kg/m2 exhibited a nonsignificant trend forlonger RFS (P=0.0674). Although multivariate analysis failed to detect any valid hazard ratio (HR), absence of PCOMand non-obesity were both independent risk factors for recurrence (P=0.00293 and P=0.0201, respectively). Notably,none of 10 cases with PCOM experienced recurrence under maintenance with oral contraceptives. Conclusion: PCOMmight be a good prognostic factor in those achieving CR after MPA therapy for EC. PMID- 29172288 TI - Prevalence of Abnormal Pap Smears: A Descriptive Study from a Cancer Center in a Low-Prevalence Community AB - Background and aims: Cervical cancer is the fourth most common cancer in women worldwide and the 13th inJordan. The cervical smear (Pap smear) is a simple approach to detect pre-cancerous cervical lesions. The aim of thisstudy was to evaluate the prevalence of abnormal cervical smears in women seen at the Early Detection/CommunityOutreach clinic of King Hussein Cancer Center (KHCC). Materials and Methods: In this retrospective study, reportsof routine cervical Pap smears performed in the pathology department at KHCC from January 2007 to December2016, were reviewed. During this period, a total of 5,529 routine smears were assessed for epithelial abnormalities andhistopathological grading. Results: A total of 210 (3.8%) abnormal Pap smears were found, with atypical squamouscell of undetermined significance (ASC-US) reported in 110 (52.4%) cases, atypical glandular cells of underminedsignificance (AGUS) in 58 (27.6%), low grade squamous intra-epithelial lesion (LSIL) in 27 (12.9%) and high gradeintra epithelial lesion (HSIL) in 13 (6.2%). Only single cases of ASC-H and squamous cell carcinoma were reported.The available biopsies showed benign findings in 70.1% of cases, low grade squamous intraepithelial lesions in 11.5%and high grade squamous intraepithelial lesions in 18.4%. Conclusions: The low epithelial cell abnormality (EPCA)prevalence illustrated in this study argues against introduction of population-based HPV testing and vaccination. Itcalls for a more cost-effective measures in a country with limited resources, where a more widely available Pap-smeartesting might suffice. PMID- 29172289 TI - Prevalence of Helicobacter Pylori Infection in Dyspeptic Patients in Andkhoy Afghanistan AB - Background: The prevalence of Helicobacter pylori (H. pylori) infection is reported to be more than 50% worldwide.It has been associated with peptic ulcer disease, gastric carcinoma, and mucosal-associated lymphoid tissue lymphoma.The seroprevalence of H. pylori varies greatly among societies and geographical locations. The objective of thisstudy was to determine the seroprevalence and factors associated with H. pylori infection among dyspeptic patientsin Afghanistan. Materials and Methods: This cross-sectional study was designed to determine the seroprevalence ofH. pylori among dyspeptic patients in an outpatient clinic in Andkhoy, Afghanistan from January 2017 to April 2017.Data were obtained from patients using a questionnaire, including socio-demographic data and history of smokingand dyspeptic symptoms. Serum samples were also collected from the patients and tested for H. pylori antibodiesusing the enzyme linked immunosorbent assay. Results: A total of 152 patients with dyspepsia were included in theanalysis; 59 were men (40.0%), and 93 were women (60.0%). The overall seroprevalence of H. pylori was 75.6%. Thepredictor of seroprevalence of H. pylori was found to be illiteracy (odds ratio [OR] 4.99, 95% confidence interval [CI]1.03!24.17), epigastric pain (OR 12.01, 95% CI 3.56- 40.52), and rural population (OR 9.66, 95% CI 3.36- 27.82).There was an inverse association between employed status and seroprevalence of H. pylori (OR 0.08, 95% CI 0.01 0.52). Conclusions: The seroprevalence of H. pylori was high among patient with dyspepsia in an outpatient clinicin Afghanistan. Illiteracy, unemployment and rural populations, and epigastric pain were significantly associated withH. pylori infection. PMID- 29172290 TI - Multi-Gene Expression in Anthracosis of the Lungs as One of the Risk Factors for Non-Small Cell Lung Cancer AB - Background: Anthracosis of the lung occurs due to the deposition of carbon and silica in the mucosa and submucosa,manifested as black lesions. The association of anthracosis with lung cancer has remained to be clearly elucidatedThe current study aimed to assess the P16, CDH1 and LUNX genes expression level to evaluate the association ofanthracotic lesions in the lungs with the occurrence of non small cell lung cancer. Methods: Forty biopsy sampleswere taken from the center and 40 from the margins of black anthracotic lesions in the lungs; RNA was extracted fromthe samples and cDNA was synthesized. Real-time reverse transcription polymerase chain reaction (RT-PCR) wasperformed to assess the expression of P16, CDH1 and LUNX genes. All steps were performed in triplicate. Results: Asignificant reduction in P16 gene expression was noted at the center compared to the margins of the lesions (P<0.001).expression level of CDH1 at the center of lesions was significantly lower than margins (P<0.001). However, LUNXgene had significantly higher expressionlevel at the center compared to margins (P<0.001). Conclusion: Decreasedexpression of P16 and CDH1 and increased expression of LUNX tumor genes were noted at the center of anthracoticlesions. Significant increase in expression of LUNX gene in NSCLC indicates an association between anthracosis andNSCLC, according to which, anthracotic patients may carry a high risk for NSCLC. PMID- 29172291 TI - The Utilization of Karyotyping, iFISH, and MLPA for the Detection of Recurrence Genetic Aberrations in Multiple Myeloma AB - Multiple myeloma (MM) is a hematological malignancy characterized by abnormal accumulation of clonal plasmacells in the bone marrow. Recently, multiplex ligation-dependent probe amplification (MLPA) has emerged as an effectiveand robust method for detection of common genetic alterations in MM patients. Here, we aimed to confirm MLPAutility for this purpose and furthermore to test the feasibility of a combination of karyotyping, interphase fluorescencein situ hybridization (iFISH) and MLPA methods for diagnosis, prognostic assessment and risk stratification of MM.Thirty-five genomic DNA samples isolated from CD138 enriched plasma cells from bone marrow of MM patients wereanalyzed using the MLPA method. We found that amp (1q) was the most frequent genetic alteration (48.6%) in the testedsamples, followed by del (1p) and del (13q) (34.3%). Moreover, concordant results between sensitivity and specificityof iFISH and MLPA for the detection of del (13q) (p-value >0.05) and del (17p) (p-value >0.05) were obtained. Insummary, we could provide evidence of MLPA assay utility for the detection of common genetic alterations in MM.The combination of karyotyping, iFISH, and MLPA proved very helpful for clinical risk stratification. PMID- 29172292 TI - Detection of Juxtapleural Nodules in Lung Cancer Cases Using an Optimal Critical Point Selection Algorithm AB - Detection of lung cancer through image processing is an important tool for diagnosis. In recent years, image processingtechniques have become more widely used. Lung segmentation is an essential pre-processing step for most (CAD)schemes. An automated system is proposed in this paper for identifying lung cancer from the analysis of computedtomography images by performing nodule segmentation using an optimal critical point selection algorithm (OCPS)which improves the detection of shape- and size-based juxtapleural nodules located at the lung boundary. A suspect areaof nodule is obtained with the help of a bidirectional chain code (BDC) approach and the OCPS This algorithm is usedto reduce the time consumption to detect the lung nodule and thereby reduce the computational complexity. Shape andsize features are extracted for the area between two critical points to facilitate classification as nodule or non nodulewith the help of a support vector machine and random forest classifiers. This automated method was tested on computedtomography (CT) studies from the lung imaging database consortium (LIDC). The results are compared with theexisting techniques using various performance measures such as precision rate, recall rate, accuracy and F-measure.The obtained experimental results indicate that the OCPS combined with a random forest classifier performs better interms of performance evaluation metrics than existing approaches, with less requirement for computation. PMID- 29172293 TI - Oncologists' Perspectives on Consolidation Radiation Treatment after Chemotherapy for Lymphomas: A Survey Study by the Lymphoma Working Committee of the Turkish Oncology Group (TOG) AB - In this study, we aimed to determine the perspectives of medical and radiation oncologists regarding consolidationradiotherapy in patients with a complete response after chemotherapy for Hodgkin's and non-Hodgkin's lymphomas.The survey was designed to identify demographic and occupational features of medical and radiation oncologists andtheir views on application of consolidation radiotherapy in their clinical practices, as based on a five-point Likert scale(never, rarely, sometimes, often, and always). The study covered 263, out of 935, physicians working in the oncologyfield as either medical or radiation oncologists; the rate of return on the invitations to participate was 28%. The majorityof the participants were male radiation oncologists, with a duration of between 5 and 10 years of work as a universityhospital official, and the mean age was 38 +/- 14 (years). Although the most commonly followed international guidelineswere NCCN, among the physicians, the majority of the respondents suggested that the guidelines were unclearregarding recommendations for consolidative radiotherapy. The administered dose for consolidative radiotherapy inlymphoma patients was indicated as 40 Gy by 49% of all the physicians and the most common cause of hesitancyconcerning consolidative radiation treatment was the risk of secondary malignancies as a long-term adverse effect(54%). In conclusion, we suggest that medical oncologists could be most active in the treatment of lymphoma througha continuous training program about lymphomas and current national guidelines. PMID- 29172294 TI - Association of Voltage-Gated Sodium Channel Genetic Polymorphisms with Oxaliplatin-Induced Chronic Peripheral Neuropathy in South Indian Cancer Patients AB - Oxaliplatin is a platinum drug active against digestive tract cancers. Among its side effects, peripheral neuropathyis one of the dose-limiting toxicities. This affects around 50 to 70% of patients but the pathophysiology of developmentof oxaliplatin-induced peripheral neuropathy (OXAIPN) remains unclear. Sodium channels (SCNAs) play major role inneuronal electrical signaling processes and mutations in SCNAs lead to various neuronal diseases involving the centraland peripheral nervous systems. In this study, we evaluated whether SCNA genetic variants might be associated withrisk of chronic OXAIPN in patients with digestive tract cancers treated with oxaliplatin. Methodology: Blood samplesfrom 228 digestive tract cancer patients who had received oxaliplatin in adjuvant and neoadjuvant or metastatic settingswere obtained and genomic DNA was extracted by phenol-chloroform extraction. Genotyping was performed withthe real-time polymerase chain reaction (RT-PCR) using validated real-time TaqMan single nucleotide polymorphism(SNP) genotyping assays. Neuropathy was evaluated and graded according to National Cancer Institute CommonToxicity Criteria (NCI-CTC) version 4.03. Results: We found that the rs6746030 polymorphic variant of SCN9A wassignificantly associated with a higher incidence of chronic OXAIPN (GA+AA vs GG: OR=1.8, 95% CI=1.04-3.4, P=0.04;dominant model) while the rs6754031 variant was linked with a lower incidence (OR=0.45, 95% CI=0.22-0.77, P=0.005;dominant model). The SCN 10A polymorphic variant was associated with severity of chronic OXAIPN (P=0.006,OR=2.0, 95% CI=1.2 - 3.3). Conclusion: The results of the present prospective study provide evidence in support ofa causal relationship between chronic OXAIPN and voltage gated sodium channel polymorphisms. However, furtherstudies from independent groups are required to validate these results. PMID- 29172295 TI - Evaluation of Mir-224, Mir-215 and Mir-143 as Serum Biomarkers for HCV Associated Hepatocellular Carcinoma AB - HCV induced hepatitis and hepatocellular carcinoma as its sequel are major health problems world-wide and especiallyin Egypt. For diagnosis and during treatment of liver diseases, liver functions are monitored through determinationof serum levels of liver enzymes and alpha-fetoprotein although the obtained information is generally not sufficient foreither early detection of hepatic insult or effective follow up of therapeutic effects. More sensitive biomarkers mayhelp to achieve these goals. MiRNAs are small non-coding RNAs that have an important role in gene expression andregulation. Many, such as miR-224, miR-215, miR-143 are correlated with tumor appearance and with the degree offibrosis in lung, breast and colon cancer. This study was performed to estimate the level of these miRNAs in serum ofpatients with HCV-associated hepatitis and HCC in relation to grade of hepatitis, stage of fibrosis and differentiation oftumor tissue. In addition, correlations between serological and tissue levels were assessed. A total of 80 patients wereexamined, out of which 50 were included in the study. Blood samples and tissue specimens from malignant tumor andcorresponding non-tumor tissue of HCV hepatitis patients were collected. Blood samples from 20 healthy volunteerswere also obtained as controls. It was found that miRNAs profiles differed in HCC patients compared to controls andHCV-associated hepatitis cases. Distinction of tumor grade and fibrosis stage of patients as well as between differentgrades of tumor differentiation proved possible, making miRNAs promising biomarkers for diagnosis and assessmentof treatment response of HCC patients. PMID- 29172296 TI - Significance of the Cytological Signs of Human Papillomavirus Infection in Anal Pap Smears of Human Immunodeficiency Virus-Infected Japanese Men Who Have Sex with Men AB - Purpose: The incidence of invasive anal cancer (IAC) has been increasing among human immunodeficiencyvirus (HIV)-positive men who have sex with men (MSM). Although cytological diagnosis is the modality of choicefor screening cases of IAC, it is associated with lower sensitivity and specificity. Therefore, the present study aimedto evaluate new cytological signs of human papillomavirus (HPV) infection that may contribute to improving analcytology. Methods: Anal cytology and HPV testing were performed using SurePath liquid-based cytology on samplesobtained from 37 HIV-positive Japanese MSM. Subsequently, a histological biopsy based on high-resolution anoscopywas performed in MSM with abnormal cytological findings indicative of atypical squamous cells of undeterminedsignificance (ASC-US) +. Also, anal Papanicolaou (Pap) smears were performed to determine cellularity, presenceof dysplastic squamous cells, and other cytological signs of HPV infection. Results: Of the 37 MSM who underwentanal cytology, six tested negative for intraepithelial lesion or malignancy, three cases exhibited ASC-US, 17 exhibitedlow-grade squamous intraepithelial lesion (LSIL), nine exhibited high-grade squamous intraepithelial lesion (HSIL),and two remained undiagnosed. The anal Pap smears of 28 (96.6%) of the 29 MSM with abnormal cytological findingsof ASC-US+ exhibited anal intraepithelial neoplasia (AIN), as revealed by histological biopsy. The median value(minimum-maximum) of the cellularity of anal Pap smears was 12 (0-70.5) nsc/hpf. In 26 MSM with LSIL and HSIL,the median dysplastic squamous cells count was 14 (2-152) dsc/smear and the cytological sign of HPV infectionwas 11 (2-71) hpv/smear. Of all anal Pap smears that revealed ASC-US+, 96.6% exhibited cytological signs of HPVinfection. Compression-positive binucleated cells were the most prevalent among all cytological signs of HPV infection.Conclusion: For anal cytology, instead of considering a small number of dysplastic squamous cells, screening basedon cytological signs of HPV infection may be beneficial for improving the diagnosis of AIN. PMID- 29172297 TI - Impact of Smoking on Health-Related Quality of Life: A General Population Survey in West Iran AB - This study was aimed at assessing any association between smoking and health related quality of life (HRQoL)among adults aged 18 years and above living in Kermanshah city, western Iran. A cross-sectional study was conducted ona total sample of 1,543 participants obtained by convenient sampling during the period from February 1st to May 30th,2017. Data were collected using a self administrated questionnaire. The HRQoL of the study participants was assessedwith reference to the EuroQol 5-dimensions-3-level (EQ-5D-3L). The impact of smoking behavior of the participantson HRQoL with controls for potential confounders was examined by multiple regression. Out of the total of 1,543participants, current smokers, past smokers, and never smokers accounted for 19.7%, 4.2% and 76.1%, respectively. Themean EQ-5D indices were 0.69 +/-SD 0.20, 0.70 +/- SD 0.22, and 0.78 +/- SD 0.16. The highest proportion of self-reportedproblems (including both 'some' and 'severe') were related to current, heavy smokers, with high nicotine dependence.Regression analysis indicated that current smokers had a significantly lower HRQoL compared to past smokers andnever smokers (p < 0.05). The heavy smokers also had a significantly lower HRQoL score than moderate and lightsmokers (p < 0.05) and there was an inverse relationship between the HRQoL score and nicotine dependence (p<0.05).The current smokers, heavy smokers, and high nicotine dependent smokers had lower HRQoL scores. These findingsprovide inputs for better understanding and for devising interventions for smoking cessation, reducing the number ofcigarettes smoked per day and nicotine dependency.

PMID- 29172299 TI - The effect of anti-IgE therapy in knee osteoarthritis: a pilot observational study. AB - Osteoarthritis is a whole-joint disease and its pathogenesis remains poorly understood. Recent evidence proposed the importance of the innate immune system as trigger of synovium inflammation following the degeneration of cartilage. Moreover, synovial mast cells (MCs) might be correlated with pain and disability reported by patients. Anti IgE therapy represents a new class of MCs stabilizing agent, licensed for people with asthma and chronic urticaria. Therefore, we studied if the stabilizing effect of anti IgE would improve the pain and disability in patients affected by knee osteoarthritis and atopic disease. This pilot study provides the first evidence that anti IgE treatment induces a short term clinical improvement supporting the role of MCs in osteoarthritis. PMID- 29172300 TI - Clinical and radiographic short mid-term outcomes of primary total stabilizer knee arthroplasty. AB - A successful Total Knee Arthroplasty (TKA) requires stability, but rarely in primary TKA, a prosthesis with more constraint than a posterior-stabilizer (PS) is necessary. In patients with severe varus/valgus deformities with incompetent collateral ligaments or in knees that cannot be adequately balanced after ligaments release, a total-stabilizer (TS) prosthesis may be required. The purpose of our retrospective study is to evaluate clinical and radiographic outcomes at short mid-term follow-up in patients treated with a TS TKA. Between January 2013 and August 2016, 36 patients (38 knees) were treated with Stryker Triathlon TS cemented implants. Clinical and radiographic evaluation were performed preoperatively and postoperatively at 1 month, 3 months, 6 months, 1 year and at 1-year intervals thereafter. At final follow-up, 33 patients (35 knees) remained and were included in this study and followed with a mean follow up of 26.6 months. Clinical evaluation was performed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC score) and the Knee Society rating system that is subdivided into a knee score (KS) that rates only the knee joint itself and a functional score (FS). Knee Score (KS) and Functional Score (FS) increased significantly from a mean pre-operative value of 48 and 45, respectively, to a post-operative value at last follow-up of 86 and 82, respectively. Also WOMAC score improved significantly: the mean pre-operative WOMAC score was 45, while the mean post-operative WOMAC score, at last follow-up, was 19. The difference between pre- and post- operative results was significant at statistical analysis. In our opinion, when the adequately prosthesis balancing isn't possible, because of primary or secondary severe varus/valgus deformity or severe soft tissues retraction, an available option is to perform a total knee arthroplasty with a total stabilizer polyethylene insert. TS prosthesis gives more stability during the most of ROM and, in addition, Triathlon system provides surgeons the possibility to choose a more constrained implant, than a standard PS one, during surgical procedure saving the bone stock. Our experience with this kind of prosthesis has provided good clinical and radiographic outcomes at a short mid-term follow-up with a low-rate of complications.

PMID- 29172306 TI - What is Restorative Dentistry? PMID- 29172307 TI - The Paradoxes of Phantom Bite Syndrome or Occlusal Dysaesthesia ('Dysesthesia'). AB - Phantom bite syndrome was first described by Marbach over 40 years ago as a mono symptomatic hypochondriacal psychosis. He used the term to describe a prolonged syndrome in which patients report that their 'bite is wrong' or that 'their dental occlusion is abnormal' with this causing them great difficulties. This strong belief about 'their bite' being the source of their problems leads to them demanding, and subsequently getting, various types of dentistry carried out by multiple dentists and 'specialists'. Sadly, even after exhaustive, painstaking, careful treatment, none of the dental treatments manages to solve their perceived 'bite problems'. This is because they suffer from a psychiatric illness involving a delusion into which they continue to lack insight, in spite of the failures of often sophisticated dental treatments.1,2,3 In summary, dental practitioners, or other specialists, who suspect that they might be dealing with such a problem should refer these patients early on for specialist management by an appropriate specialist within the secondary care settings, preferably before they get trapped into the time-consuming quagmire of their management. A 'Phantom Bite Questionnaire', which is available to download free, might help. Clinical relevance: This article aims to provide professionals in various fields with guidelines on detecting, diagnosing and managing patients with Phantom Bite Syndrome (PBS). This is desirable in order to prevent extensive, or unnecessarily destructive, or unstable dental treatment being undertaken on such patients in a vain attempt to solve their problems with 'dentistry' when, in fact, these are really due to underlying mental health issues. PMID- 29172308 TI - A New Perspective on Dentine Hypersensitivity - Guidelines for General Dental Practice. AB - The aim of this review is to update dental professionals on the issues and challenges associated with the clinical management of dentine hypersensitivity (DH) and to provide simple guidelines based on presenting clinical features that may help them successfully manage the condition in their day-to-day clinical practice. Details on the management of DH have been previously published in Dental Update which indicated that there was a need for such guidelines. The authors of these guidelines also suggested that, despite the various published clinical studies, there does not currently appear to be one ideal desensitizing agent that can be recommended for treating DH. A joint working relationship between the dental professional and the patient in changing the patient's behaviour is therefore essential if the condition is to be successfully treated. Clinical relevance: Dentine hypersensitivity is a persistent and a troublesome clinical condition which at times is under diagnosed by dental professionals who may struggle to resolve the problem to their patients' satisfaction successfully. The recent UK Forum guidelines on the management of DH, based on the presenting features of the condition, provide practical recommendations, helping dental professionals to manage this persistent problem correctly.

AB - Dental fear in the paediatric population can be a significant barrier to providing optimal dental care. Pharmacological management techniques utilized to manage anxiety, such as conscious sedation and general anaesthesia, are expensive and require specialized equipment with additional staff training. With recent advances in technology, video glasses are an economic and novel distraction technique that may aid in improving behaviour management and facilitate dental treatment. Clinical relevance: Nervous children may find difficulty in accessing care owing to their inability to co-operate and accept dental treatment. This paper describes an innovative technique that may aid the clinician in overcoming this barrier. PMID- 29172311 TI - Case Report: Metastatic Infratemporal Soft Tissue Myeloma Presenting as a Numb Lower Lip.

PMID- 29172314 TI - The Limitations of Short-Term Orthodontics and Why We Still Need Specialists - A Review of the Current Literature. AB - Short-term orthodontics (STO) serves to align anterior teeth. It has become popular in cosmetic dentistry as an alternative to destructive veneers and lengthy conventional orthodontics. The aim of this article is to raise awareness of the clinical limitations of STO and highlight some of the difficulties encountered with orthodontic retention. It also gives an overview of accredited training available to dentists who wish to develop their orthodontic skills. Clinical relevance: Greater awareness of the clinical limitations of short-term orthodontics will aid GDPs in appropriately selecting their cases and obtaining informed consent from patients. In addition, the article serves as encouragement for those GDPs wishing to develop their orthodontic skills and pursue further accredited training.

AB - This review article aims to analyse whether patient feedback and questionnaires improve quality of care. It is recognized that patients cannot assess the medical competence of the clinician, yet patient experience provides an insight into the process of care through the patients' eyes. Patient experience measures are more reliable for use to assess quality than patient satisfaction surveys. It is inappropriate to use patient satisfaction surveys as a basis for remuneration of dentists within the NHS. Patient Reported Outcome Measures (PROMs) have been a successful measure of patient experience in medicine and their introduction to dentistry needs to be considered. Clinical relevance: This article will enable clinicians to understand the importance of patient experience measures as a more reliable way of improving the quality of clinical care than patient satisfaction surveys.

This article reports the case of a large dentigerous cyst in the maxilla affecting the eruption of multiple teeth, considers the use of CBCT in the management of such lesions, and discusses guidelines on the use of CBCT in dentistry. Clinical relevance: As CBCT use increases it is important that practitioners understand the guidelines surrounding its use. Due to the prevalence of dentigerous cysts, it is likely that they will be encountered clinically, and it is important that clinicians referring patients with such lesions are familiar with the principles of managing them.

PMID- 29172325 TI - Periodontal Treatment in Patients with Learning Disabilities Part 2: Professional Mechanical Intervention. AB - The first part of this two part series discussed the potential barriers and risk factors that may lead to an increased incidence and severity of periodontal disease amongst patients with learning disabilities. Additionally, preventive strategies and tools that can be used by general dental practitioners, oral health promotion teams as well as specialists within the field to control and prevent disease progression were explored. To prevent periodontal disease progression and attain optimal periodontal health, a combination of prevention and professional mechanical instrumentation is usually required. The second part of the series concentrates on the role of the dental professional in implementing professional mechanical instrumentation to attempt to reduce the burden of disease further in this patient group. Clinical relevance: Although research continues into which professional techniques for instrumentation are the most successful amongst patients with periodontal disease, very little data specifically explore the needs of patients with learning disabilities, despite their high unmet needs. This paper aims to report on any available data present to produce suggestions for care. PMID- 29172326 TI - Efficient Mass Transport.

AB - Salivary gland damage is the most common adverse effect associated with radiation therapy to the head and neck. A combination of hyposalivation and dietary changes, with a reduced emphasis on oral hygiene practices can contribute to a massive increase in a person's caries risk status. This can be further complicated by limited mouth opening. To enable optimal dental care for head and neck cancer patients before, during and after radiation therapy, patients must be informed and educated about the potential risks of dental caries and the preventive strategies available. All patients should receive a pre-radiotherapy dental assessment by a Restorative Dentistry Consultant. This information will be delivered to the patient, often at an emotionally charged time, and can be lost amongst all the information related to other aspects of his/her cancer management. General Dental Practitioners (GDPs) are therefore in a pivotal position to reiterate this information post radiation therapy and ensure compliance with preventive strategies, with the overall aim to improve quality of life and avoid the need for future extractions and the resulting risk of osteoradionecrosis. Clinical relevance: This article highlights the GDP's role in the shared management of head and neck cancer patients who have received radiotherapy as part of their cancer treatment. The critical issue of dental caries, one of the late effects of radiation-induced hyposalivation, will be focused upon. Other side-effects, such as trismus and osteoradionecrosis, will also be discussed. This article aims to supply GDPs with accurate information to provide to their patients with post radiation therapy, whilst highlighting what treatment is within their remit and when it may be appropriate to refer. PMID- 29172329 TI - Treatment Planning for Mandibular Third Molars. AB - NICE guidance for mandibular third molars has been available since 2000. This was set up to limit the surgical treatment of these teeth to symptomatic patients. There are numerous risks involved with surgical treatment of mandibular third molars and these should be explained in detail to the patient. Common and serious complications of mandibular third molar surgery are damage to the inferior alveolar and lingual nerve. Predicting the risk of inferior alveolar nerve injury is useful for treatment planning. The orthopantomogram (OPT) is the baseline special test for assessing this and numerous signs on an OPT can predict an increased risk of injury to the nerve. Cone beam computed tomography (CBCT) is being more frequently used to assess this relationship further and can influence treatment planning. Coronectomy is a technique whereby the crown of the tooth is sectioned and removed leaving the roots in situ. This has proven to be a useful technique in high risk cases, but is not without its own complications. The increase in availability of CBCT imaging and the recent resurgence of coronectomy as a treatment modality can increase the number of treatment options available to patients. We have proposed an algorithm to aid the treatment planning and informed consent processes associated with mandibular third molar surgery. Clinical relevance: This article is relevant to primary and secondary care dental practitioners as it will aid the investigation, treatment planning, correct referral and management of patients with problematic mandibular third molars. PMID- 29172328 TI - Surgical Emphysema: A Rare Complication of a Simple Surgical Dental Extraction Without the Use of an Air-Driven Rotor. AB - Surgical emphysema is a rare complication of dental extractions, often associated with the use of high-speed air rotors. This report describes a case of extensive surgical emphysema following a simple surgical extraction of a LL6 under local anaesthetic. There was no use of air-driven handpieces during the procedure. The patient developed extensive surgical emphysema bi-laterally in both cervical neck and facial planes. After prophylactic antibiotics with careful monitoring in a secondary care setting, the patient made a full unremarkable recovery. Clinical relevance: Simple extraction of teeth is a procedure carried out daily by most general dental practitioners. However, the risk of surgical emphysema without the use of high-speed air rotors or instruments using pressurized air/water is not well known or documented. PMID- 29172330 TI - Waterlogged.

This report discusses a 6-year-old female, presenting in the Emergency Department with unilateral facial weakness. Initially thought to be facial swelling relating to her carious dentition, clinical assessment from the maxillofacial team identified that the patient had a unilateral facial palsy, later diagnosed as Bell's palsy. Her delayed presentation was due to initial misdiagnoses in primary care. This case report aims to highlight its aetiology, clinical features and appropriate management. Clinical relevance: To make the general dental practitioner aware of different causes of facial paralysis, and to provide GDPs with an algorithm to follow in the presentation of a facial palsy in the primary care setting. PMID- 29172336 TI - The Immune System: Basis of so much Health and Disease: 2. Innate Immunity.

AB - Fourteen dentists at different practices in the UK assessed the dental charts of 1128 patients who were new to the dentist but not new to the practice; 44% of the dental charts were found to be inaccurate. Inaccuracy of the individual practice based charts ranged between 16% for the best performing practices to 83% for the worst: 5% of dental charts had too many teeth charted and 5% had too few teeth charted; 13% of charts had missed amalgam restorations and 18% had missed tooth coloured restorations; 5% of charts had amalgam restorations recorded but with the surfaces incorrect (eg an MO restoration charted but a DO restoration actually present); 9% of charts had tooth-coloured restoration surfaces incorrectly recorded. For 7.5% of charts, amalgams were charted but not actually present. Other inaccuracies were also noted. The authors reinforce the requirements of the GDC, the advice of defence organizations, and the forensic importance of accurate dental charts. Clinical relevance: Dental charting forms part of the patient's dental records, and the GDC requires dentists to maintain complete and accurate dental records.

AB - The increasing emergence of antibiotic resistance is a major international public health problem. As a consequence, it is essential that steps are taken to conserve the effectiveness of existing antimicrobial agents. Consumption of antibiotics is the prime contributor to the development of resistance. General dental practitioners write almost 1 out of 10 prescriptions for antibiotics in primary care within the UK and therefore the prudent prescribing of antibiotics in dentistry has never been more vital. This paper outlines the impact of antimicrobial resistance on modern healthcare, describes the current use of antibiotics in general dental practice, and recommends pragmatic ways in which dental practitioners can evaluate and optimize their prescribing. Clinical relevance: Dental professionals have a responsibility to both their patients and the wider community to prescribe antibiotics appropriately. PMID- 29172347 TI - Safe and Sound.

AB - A growing problem in dentistry is complications associated with failing amalgam restorations that have been in place for many years. At present, there is a wide variety of treatment options available in the clinician's armamentarium when this situation arises, however, without the correct diagnosis, the prognosis for the tooth may quickly diminish, despite the clinician's best efforts. A confusing array of symptoms and failures may confound even the most experienced dentist, which will inevitably lead to invasive and time consuming approaches in a desperate attempt to rectify the initial problem. This paper, the first part of a three-part series, discusses the possible aetiological factors responsible for restoration failure, including occlusal issues and cracks within the tooth structure. The second part of the series will focus on restorative options and root-treated teeth. The third, and final, part of the series will provide an overview of the previous papers and conclude with a case report. Clinical relevance: Failure of amalgam restorations is a commonly encountered clinical problem in general practice and no one case presents in the same way. A competent diagnosis regarding the occlusion and tooth structure, followed with implementation of the most appropriate, minimally invasive treatment option, requires an adequate knowledge of current literature.

This article describes the case of a 4-year-old boy affected by childhood hypophosphatasia, who presented with premature exfoliation of his primary teeth as the first manifestation of this condition. An overview of the condition is outlined including a discussion of the likelihood of permanent dentition involvement.Clinical relevance: Oral manifestations of hypophosphatasia may be the first and the only signs of this condition and may be the basis upon which a diagnosis is made. PMID- 29172357 TI - The Role of Fibrinolytic Therapy in the Emergency Department. AB - Emergency physicians are many times the first-line practitioners to encountercirculatory emergencies. Amongst these many diseases we face, of importanceare acute myocardial infarction, ischemic cerebrovascular accidents and pulmonaryembolism. Familiarity with fibrinolytic agents and regimens, as well as indicationsand contraindications, are crucial to the emergency department physician.Fibrinolytic therapy has been shown to be beneficial and can serve as a bridge todefinite treatment, while lowering the risk of morbidity and mortality. Unfortunatelyfibrinolytic therapy is underused and often administered later than optimum.The aim of fibrinolytics is to dissolve blood clots that can cause serious and potentiallylife-threatening damage if not removed in a timely manner. The mechanism ofthis benefit relates to maximizing tissue salvage by early restoration of blood flowand thereby enhancing both early and long-term survival. Older thrombi haveextensive fibrin polymerization making them more resistant to thrombolysis;hence, the importance of early administration of fibrinolytic therapy. PMID- 29172358 TI - The Immune System: Basis of so much Health and Disease: 3. Adaptive Immunity. AB - The immune system is the body's primary defence mechanism against infections, and disturbances in the system can cause disease if the system fails in defence functions (in immunocompromised people), or if the activity is detrimental to the host (as in auto-immune and auto-inflammatory states). A healthy immune system is also essential to normal health of dental and oral tissues. This series presents the basics for the understanding of the immune system; this article covers adaptive immunity. Clinical relevance: Dental clinicians need a basic understanding of the immune system as it underlies health and disease. PMID- 29172359 TI - What's New in Dentine Bonding?: Universal Adhesives. AB - The ability to bond restorations to dentine successfully is central to minimally invasive restorative dentistry. While dentine-bonding agents have gone through a variety of 'generations', it is the purpose of this paper to describe the latest dentine-bonding agents, the Universal Bonding Agents. These materials may be considered 'Universal' insofar as they may be considered to be capable of being used for direct and indirect dentistry, as well as being suitable for use in whichever etching modality the clinician considers appropriate, namely self-etch, etch and rinse or selective enamel etch. Laboratory investigations and initial clinical studies hold the promise that Universal Bonding Agents are a forward step in the quest for the ultimate bond to tooth substance.Clinical relevance: New Universal Bonding Agents appear to present a promising advance in bonding to dentine.

AB - On 15 October 2015, The Resuscitation Council (UK) published new resuscitation guidelines following the review of resuscitation science by the International Liaison Committee on Resuscitation (ILCOR). The 2015 guidelines emphasize the importance of interactions between the emergency medical dispatcher, the bystander who provides cardiopulmonary resuscitation (CPR) and the prompt deployment of an automated external defibrillator (AED); the co-ordination of these three elements is crucial to improving out-of-hospital cardiac arrest survival. Medical emergencies in dental practices are thought to occur on average once every 3-4 years per dentist in primary care. The GDC consider medical emergencies as a highly recommended topic for Continuing Professional Development (CPD) and recommend at least 10 hours in every CPD cycle. Clinical relevance: The publication of the updated guidelines serves as a reminder to the clinical team of the importance of being up to date with recognition and treatment of cardiac arrest and choking and how seamless interaction between members of both the dental and medical teams improves long-term outcomes for patients. PMID- 29172365 TI - Psoriasis and Coronary Artery Disease in Hispanics. AB - Psoriasis is an immune disorder characterized by chronic activation of systemicinflammation. Morbidity and mortality in patients with psoriasis is attributedmainly to cardiovascular disease. There are studies in Caucasians and African-Americans, but little is known about how psoriasis is associated to coronaryartery disease (CAD) in Hispanics. We intend to describe the angiographic findingsof a group of Puerto Rican patients with psoriasis. Retrospective cohort studyof 46 patients with psoriasis were studied. Coronary angiographic reports werereviewed, and collected data was statistically analized. Population median agewas 56, and 72% were males. Of the 46 patients, 27 had CAD by angiographiccriteria (58.7%). Twelve patients were referred to bypass graft surgery, 8 underwentcoronary stent placement, and 7 were treated medically. Whether psoriasiscan be considered a risk factor for developing CAD is still on debate. Morethan 50% of our patients with psoriasis had angiographic evidence of CAD. Adjustingfor traditional cardiovascular risk factors, we found no significant association(p>0.05) with CAD. We believe that inflammation plays a contributing rolein the increased risk of CAD in these patients. The importance of this study relieson being the first retrospective analysis in a group of Hispanics trying to determinean association between coronary artery disease and psoriasis when in PuertoRico, coronary artery disease is 30% less than in the United States.

In this paper we introduce toyou an observational study, in which a series of patients with this complicationwhere managed by using elastic compression hat during 18 hours per day,for two weeks to four months. Every one of them presented complete resolutionof the leak, without any recurrence until actual controls. After that we perform areview of the literature, demonstrating this is a new therapeutic management,being us the first group on reporting it. According to the observed results, it wasconcluded that despite more studies are required, the use of elastic compressionhats for this kind of patients could be effective and safe. PMID- 29172370 TI - Previous Exposure to Anesthesia and Autism Spectrum Disorder (ASD): A Puerto Rican Population-Based Sibling Cohort Study. AB - BACKGROUND: Autism Spectrum Disorder (ASD) is characterized by impaired social interactionand communication, and by restricted and repetitive behavior, that beginsusually before a child is three yearsold.(1) Researchers have shown that prevalencerates in the U.S. may be as high as 1 in 68.(52) A number of studies haveexamined the effects of early exposure to anesthesia on brain development andsubsequent impairment in neurocognitive function; yet, little is known aboutthe possible effects of anesthetic agents on social-behavioral functioning. Theassociation between exposure to anesthesia either in uterus, during the firstyears of life, or later and development of Autistic Spectrum Disorder (ASD) or itsseverity was determined in a retrospective population based cohort study. OBJECTIVES: Identify if children who had previous exposureto anesthesia either in uterus, first years of life during their developing brainyears, or later, are at risk of developing ASD and its severe form of the disease. METHODS: Data was obtained from structured interviews administered to a sample of 515parents/guardians distributed in two groups: ASD = 262 children diagnosedwith this condition and Non-ASD: 253 children (siblings of ASD group) withoutdiagnosis (95% confidence interval) that freely decided to participate and agreedto a consent form. Variables studied include: demographics, diagnosis andseverity of ASD, exposure to anesthesia, method of childbirth, and age of exposureChildren less than 2 years of age were considered into have developingbrain period. Data was analyzed using Chi-square or Fisher exact test. RESULTS: In contrast to non ASD group, most of the children within ASD group weremale, 76% (p=0.0001). With regards to methods of childbirth, 64% of the ASDpopulation were vaginal delivery (VD; Non-anesthesia exposure group) and36% cesarean delivery (CD) compared to non autistic population with 71%VD and 29% CD, which demonstrates no statistical difference between bothgroups (p=0.1113). Out of the 36% of ASD population that underwent CD,7% were performed using general anesthesia and 93% regional anesthesia,while the 29% of the CD of non-ASD, 5% were performed using general anesthesiaand 95% regional anesthesia. This reveals no statistical significance(p=0.7569) with the development of ASD and the type of anesthesia usedwhen comparing ASD with non-ASD patients. In view of severity of autism, inVD, 56% of ASD population had mild form of the disorder, 34% moderate, and10% severe; while CD had a 54% mild form of the disorder, 33% moderate, and13% severe. This shows no statistical association (p=0.8069) when comparingexposure to anesthesia in uterus to subsequent severe form of ASD.Of the 262 ASD patients, 99 had exposure to anesthetics before their diagnosis,while in Non-ASD population, 110 had exposure to anesthesia, demonstratingno statistically significant association between both groups (p=0.2091).Out of 99 ASD patients exposed to anesthesia prior to their diagnosis, 72 wereexposed before age 2. When compared to the 110 Non-ASD patients exposedto anesthesia, 86 had exposure during this developing brain period, which indicatesno statistically significant association (p=0.4207). In addition, most ofthe ASD children exposed to anesthesia during developing brain were diagnosedwith mild degree of the disorder when compared to ASD children withoutany previous exposure to anesthesia (p=0.9700) during the same period.When the exposure occurred after age 2, ASD children developed mild formof the disorder as compared with ASD children without any previous exposureto anesthesia (p=0.1699) in that period. CONCLUSIONS: Children under early exposure to anesthesia in uterus, first 2 years of life, or later are not more likely to develop neither ASD nor severe form of the disorder. PMID- 29172371 TI - Analysis of clinical characteristics of dialysis patients at the University Hospital. AB - OBJECTIVES: The incidence and prevalence of Chronic Kidney Disease (CKD)patients treated with dialysis has continued to increase worldwide. These patientsare at the highest risk of developing cardiovascular complications whichcontribute to their demise. The objective of this study was to describe the clinicaland demographic characteristics of the patients on maintenance hemodialysisat the University Hospital, in San Juan Puerto Rico. METHODS: We reviewed a total of 55 active patients. Data was collected toidentify the demographic and clinical characteristics. Co-morbid conditionssuch as diabetes mellitus, hypertension, and coronary artery disease (CAD)were noted as well as age, dialysis vintage and social and educational profiles. RESULTS: Patients were divided into two groups according to age (group 1 wereless than 60 years and group 2 were more than 60 years). Average age was 42 yearsin group 1 with 17 females and 24 males and 78 years in group 2 with 6 femalesand 8 males. Diabetes mellitus was present in 17 (41%) of group 1 and 5 patients(35%) of group 2. Likewise hypertension was present in 26 (63%) of group 1 patientsand 11(78%) of group 2 patients. CAD was present in 15 (36%) of group 1patients and 7 (50%) of group 2 patients. There was an association between lowannual income in both groups but not in the level of education. CONCLUSION: A relatively young population was identified in our descriptiveanalysis of hemodialysis patients at the University Hospital. The expected highincidence of diabetes mellitus observed in the general population of hemodialysispatients in our country was not present. Hypertension and CAD weremajor risk factors in these patients. In view of these findings we recommendbetter control of blood pressure, prevention and early detection of CAD inCKD patients before initiating dialysis. PMID- 29172372 TI - ? PMID- 29172373 TI - ? PMID- 29172374 TI - False Dawns and New Horizons in Patient Safety Research and Practice. AB - In response to a weight of evidence that patients are frequently harmed as a result of their care, there have been concerted efforts to make healthcare safer, with health systems across the globe investing significant resources in policies and programmes designed to reduce adverse events. Yet, despite extensive efforts, improvements in safety have proved difficult to sustain and spread, with studies confirming there has been no measurable, systems-level improvement in the overall rates of preventable harm. Here, we highlight the limitations of the thinking which underpins current efforts to make healthcare systems safer and point to new and emerging approaches to understanding and addressing patient safety in complex, dynamic health systems.

PMID- 29172376 TI - Does Scale of Public Hospitals Affect Bargaining Power? Evidence From Japan. AB - BACKGROUND: Many of public hospitals in Japan have had a deficit for a long time. Japanese local governments have been encouraging public hospitals to use group purchasing of drugs to benefit from the economies of scale, and increase their bargaining power for obtaining discounts in drug purchasing, thus improving their financial situation. In this study, we empirically investigate whether or not the scale of public hospitals actually affects their bargaining power. METHODS: Using micro-level panel data on public hospitals, we examine the effect of the scale of public hospitals (in terms of the number of occupancy beds) on drug purchasing efficiency (DPE) (the average discount rate in purchasing drugs) as a proxy variable of the bargaining power. Additionally, we evaluate the effect of the presence or absence of management responsibility in public hospital for economic efficiency as the proxy variable of an economic incentive and its interaction with the hospital scales on the bargaining power. In the estimations, we use the fixed effects model to control the heterogeneity of each hospital in order to estimate reliable parameters. RESULTS: The scale of public hospitals does not positively correlate with bargaining power, whereas the management responsibility for economic efficiency does. Additionally, scale does not interact with management responsibility. CONCLUSION: Giving management responsibility for economic efficiency to public hospitals is a more reliable way of gaining bargaining power in drug purchasing, rather than promoting the increase in scale of these public hospitals. PMID- 29172377 TI - Should Employers Be Permitted not to Hire Smokers? A Review of US Legal Provisions. AB - BACKGROUND: Increasingly, healthcare and non-healthcare employers prohibit or penalize the use of tobacco products among current and new employees in the United States. Despite this trend, and for a range of different reasons, around half of states currently legally protect employees from being denied positions, or having employment contracts terminated, due to tobacco use. METHODS: We undertook a conceptual analysis of legal provisions in all 50 states. RESULTS: We found ethically relevant variations in terms of how tobacco is defined, which employee populations are protected, and to what extent they are protected. Furthermore, the underlying ethical rationales for smoker protection differ, and can be grouped into two main categories: prevention of discrimination and protection of privacy. CONCLUSION: We critically discuss these rationales and the role of their advocates and argue that enabling equality of opportunity is a more adequate overarching concept for preventing employers from disadvantaging smokers. PMID- 29172378 TI - How Are New Vaccines Prioritized in Low-Income Countries? A Case Study of Human Papilloma Virus Vaccine and Pneumococcal Conjugate Vaccine in Uganda. AB - BACKGROUND: To date, research on priority-setting for new vaccines has not adequately explored the influence of the global, national and sub-national levels of decision-making or contextual issues such as political pressure and stakeholder influence and power. Using Kapiriri and Martin's conceptual framework, this paper evaluates priority setting for new vaccines in Uganda at national and sub-national levels, and considers how global priorities can influence country priorities. This study focuses on 2 specific vaccines, the human papilloma virus (HPV) vaccine and the pneumococcal conjugate vaccine (PCV). METHODS: This was a qualitative study that involved reviewing relevant Ugandan policy documents and media reports, as well as 54 key informant interviews at the global level and national and sub-national levels in Uganda. Kapiriri and Martin's conceptual framework was used to evaluate the prioritization process. RESULTS: Priority setting for PCV and HPV was conducted by the Ministry of Health (MoH), which is considered to be a legitimate institution. While respondents described the priority setting process for PCV process as transparent, participatory, and guided by explicit relevant criteria and evidence, the prioritization of HPV was thought to have been less transparent and less participatory. Respondents reported that neither process was based on an explicit priority setting framework nor did it involve adequate representation from the districts (program implementers) or publicity. The priority setting process for both PCV and HPV was negatively affected by the larger political and economic context, which contributed to weak institutional capacity as well as power imbalances between development assistance partners and the MoH. CONCLUSION: Priority setting in Uganda would be improved by strengthening institutional capacity and leadership and ensuring a transparent and participatory processes in which key stakeholders such as program implementers (the districts) and beneficiaries (the public) are involved. Kapiriri and Martin's framework has the potential to guide priority setting evaluation efforts, however, evaluation should be built into the priority setting process a priori such that information on priority setting is gathered throughout the implementation cycle.

It critically examines two of its key concepts: populism and 'post truth.' This commentary argues that there are different types of populism, with unclear links to impacts, and that in some ways, 'post-truth' has resonances with arguments advanced in the period at the beginning of the British National Health Service (NHS). In short, 'post-truth' populism' may be 'deja vu all over again,' and there are multiple (post) truths: this is my (post) truth, tell me yours.

AB - Addressing the increasingly globalised determinants of many important problems affecting human health is a complex task requiring collective action. We suggest that part of the solution to addressing intractable global health issues indeed lies with the role of new legal instruments in the form of globally binding treaties, as described in the recent article of Nikogosian and Kickbusch. However, in addition to the use of international law to develop new treaties, another part of the solution may lie in innovative use of existing legal instruments. A 2015 court ruling in The Hague, which ordered the Dutch government to cut greenhouse gas emissions by at least 25% within five years, complements this perspective, suggesting a way forward for addressing global health problems that critically involves civil society and innovative use of existing domestic legal instruments. PMID- 29172382 TI - Ensuring HIV Data Availability, Transparency and Integrity in the MENA Region Comment on "Improving the Quality and Quantity of HIV Data in the Middle East and North Africa: Key Challenges and Ways Forward". AB - In this commentary, we elaborate on the main points that Karamouzian and colleagues have made about HIVdata scarcity in Middle Eastern and North African (MENA) countries. Without accessible and reliable data, no epidemic can be managed effectively or efficiently. Clearly, increased investments are needed to bolster capabilities to capture and interpret HIV surveillance data. We believe that this enhanced capacity can be achieved, in part, by leveraging and repurposing existing data platforms, technologies and patient cohorts. An immediate modest investment that capitalizes on available infrastructure can generate data on the HIV burden and spread that can be persuasive for MENA policy makers to intensify efforts to track and contain the growing HIV epidemic in this region. A focus on key populations will yield the most valuable data, including among men who have sex with men (MSM), transgender women and men, persons who inject drugs (PWIDs), female partners of high risk men and female sex workers.

PMID- 29172385 TI - Single-Bundle versus Double-Bundle Posterior Cruciate Ligament Reconstruction: A Meta-Analysis of Randomized Controlled Trials. AB - Purpose: This meta-analysis evaluated the benefits of single-bundle (SB) and double-bundle (DB) surgical techniques for posterior cruciate ligament reconstruction (PCLR) in terms of clinical outcomes. Methods: Five electronic databases were searched for relevant articles published until September 2016. Clinical outcomes of both techniques were evaluated using Lysholm knee function scores, Tegner activity scores, side-to-side differences, and International Knee Documentation Committee (IKDC) objective grades. The results are presented as a risk ratio (RR) for binary outcomes and a weighted mean difference (WMD) for continuous outcomes with a 95% confidence interval (CI). Results: Four randomized controlled trials (RCTs) were included. There were no significant differences in the Lysholm knee function scores (WMD=1.63; 95% CI, 0.00 to 3.27; I2=0%), Tegner activity scores (WMD=0.17; 95% CI, -0.08 to 0.43; I2=20%), side-to-side differences (WMD=-0.97; 95% CI, -2.41 to 0.47; I2=78%), and IKDC objective grades (RR=1.18; 95% CI, 1.00 to 1.39; I2=0%) at the final follow-up. Conclusions: The present study demonstrates that both SB and DB techniques for PCLR are comparable in terms of restoration of knee stability and improvement of knee function. However, it is still unclear which technique yields better clinical outcomes. To verify and further corroborate our results, more larger-scale, high-quality RCTs are encouraged. PMID- 29172387 TI - Comparison of an Accelerometer-Based Portable Navigation System, Patient-Specific Instrumentation, and Conventional Instrumentation for Femoral Alignment in Total Knee Arthroplasty. AB - Purpose: The KneeAlign2 (KA2, OrthoAlign Inc.) accelerometer-based portable navigation system and patient-specific instrumentation (PSI; Signature, ZimmerBiomet) are widely used for ideal femoral component alignment in total knee arthroplasty (TKA). However, there has been no comparative study of the KA2 system, PSI, and conventional intramedullary instrumentation (CON). The purpose of this study was to compare the accuracy in achieving proper femoral component alignment and clinical features by using the KA2 navigation system, PSI, and CON. Materials and Methods: We retrospectively compared the accuracy of femoral component alignment of 34 TKAs performed with the KA2 system for implantation of the femoral component, 32 TKAs with PSI, and 33 TKAs with CON. Results: In the coronal plane, use of the KA2 system was more likely to result in optimal femoral component alignment than the CON and PSI (p<0.01). In the sagittal plane, use of the KA2 system was more likely to result in optimal component alignment than PSI, but the difference between the KA2 and CON was insignificant. Conclusions: The portable accelerometer-based KA2 navigation system enabled ideal femoral implantation in the coronal and sagittal planes, as compared to the PSI or CON.

PMID- 29172388 TI - Does Combination Therapy of Popliteal Sciatic Nerve Block and Adductor Canal Block Effectively Control Early Postoperative Pain after Total Knee Arthroplasty? AB - Purpose: We compared adductor canal block (ACB) alone and a combination of ACB and sciatic nerve block (SNB) to control early postoperative pain after total knee arthroplasty. Materials and Methods: One hundred patients received continuous ACB alone (group A), and another 100 patients received continuous ACB and single popliteal SNB (group B). Pain was evaluated at rest and 45 degrees knee flexion using the numeric rating scale (NRS). The number of times the patient pressed the intravenous patient-controlled analgesia (PCA) button, total PCA volume infused, and the total dosage of additional analgesics were evaluated. We also investigated complications associated with each pain control technique. Results: The NRS score on postoperative day 1 was significantly lower in group B than in group A. The number of times patients pressed the PCA button on postoperative day 1 and the total infused volume were significantly lower in group B than in group A. Thirty-five (35%) patients in group B developed foot drop immediately after surgery; but they all fully recovered on postoperative day 1. Conclusions: SNB can be effective for management of early postoperative pain that persists even after ACB. Further research is needed to determine the proper dosage and technique for reducing the incidence of foot drop. PMID- 29172389 TI - Full Cementation in Revision Total Knee Arthroplasty Using a Constrained Condylar Knee Prosthesis with an Average 7-Year Follow-up. AB - Purpose: To evaluate clinical and radiological outcome of the full cementation technique in revision total knee arthroplasty (TKA) using a constrained condylar knee (CCK) prosthesis. Materials and Methods: Between January 2008 and March 2012, 18 cases (16 patients) of fully cemented revision TKA were performed using a CCK prosthesis. Fifteen cases of aseptic loosening (13 patients) and 3 cases of infection were included. There were 2 males and 14 females with a mean age of 76.7 years at the time of surgery, and the average follow-up was 81 months. Clinically, the pain score, function score and Hospital for Special Surgery (HSS) score were evaluated. Radiologically, loosening, radiolucent lines and migration of implant were evaluated. Results: Preoperatively, the pain score, function score and HSS score were 50.3, 24.4 and 61.8 points, respectively. At the latest follow-up, the scores were improved to 84.8, 63.6 and 85.6 points, respectively (p<0.05). Loosening or migration of implant was not observed in any cases. Radiolucent lines were observed in 5 cases underneath the tibial component without progression during the follow-up. Conclusions: The full cementation technique in revision TKA using a CCK showed excellent clinical results. Although radiolucent lines were observed in 27.8% underneath the tibial component, there was no progression to loosening or instability. PMID- 29172390 TI - Meniscal Extrusion Progresses Shortly after the Medial Meniscus Posterior Root Tear. AB - Purpose: Medial meniscus posterior root tears (MMPRT) induce medial meniscus extrusion (MME). However, the time-dependent extent of MME in patients suffering from the MMPRT remains unclear. This study evaluated the extent of MME after painful popping events that occurred at the onset of the MMPRT. Materials and Methods: Thirty-five patients who had an episode of posteromedial painful popping were investigated. All the patients were diagnosed as having an MMPRT by magnetic resonance imaging (MRI) within 12 months after painful popping. Medial meniscus body width (MMBW), absolute MME, and relative MME (100*absolute MME/MMBW) were assessed among three groups divided according to the time after painful popping events: early period (<1 month), subacute period (1-3 months), and chronic period (4-12 months). Results: In the early period, absolute and relative MMEs were 3.0 mm and 32.7%, respectively. Absolute MME increased up to 4.2 mm and 5.8 mm during the subacute and chronic periods, respectively. Relative MME also progressed to 49.2% and 60.3% in the subacute and chronic periods, respectively. Conclusions: This study demonstrated that absolute and relative MMEs increased progressively within the short period after the onset of symptomatic MMPRT. Our results suggest that early diagnosis of an MMPRT may be important to prevent progression of MME following the MMPRT.

AB - We describe a patient who underwent arthroscopic pullout fixation for a posterior cruciate ligament (PCL) avulsion fracture. A 46-year-old female, injured in a fall while riding a motorcycle, was diagnosed with a right knee PCL tibial attachment avulsion fracture and underwent arthroscopic osteosynthesis. A Kirschner wire was drilled to a point just medial to the medial border of the anterior tibial bony bed. A suture wire was folded into a loop and introduced into the posteromedial compartment via the bone tunnel. A fixation thread was inserted from the posteromedial portal, through the medial and lateral loop wires, and into the posteromedial compartment. The lateral and medial loop wires attached to the thread were pulled to the outside, and the thread was fixed onto the tibia. Three months post-surgery, she returned to her job. This procedure represents a minimally invasive method of treating avulsion fractures of the tibial attachment of the PCL.

AB - Purpose: This study evaluated the efficacy of a smartphone application in the measurement of rotation angles in porcine knees. Materials and Methods: Two K wires were fixated to the femoral condyle and anterior tibial crest of 10 porcine legs. The angle created between the K-wires with an external rotation force applied was measured on a photograph and defined as the true angle. The same force was applied to the legs placed on a splint with a smartphone attached to the plantar side. The angle presented on a smartphone application was determined as the measured angle. The differences between the true and measured angles in 30 degrees and 90 degrees knee flexion and differences in measured angles depending on the status of the popliteus tendon were compared. Results: In the intact knees, the mean true angles in 30 degrees and 90 degrees flexion were 20.5 degrees +/-1.4 degrees and 19.1 degrees +/-1.3 degrees , respectively, and the mean measured angles in 30 degrees and 90 degrees flexion were 21.1 degrees +/-0.9 degrees and 18.6 degrees +/-1.6 degrees , respectively. When the popliteus tendon was cut, the mean true angles in 30 degrees and 90 degrees flexion were 31.4 degrees +/-1.1 degrees and 38.5 degrees +/-2.5 degrees , respectively, and the mean measured angles in 30 degrees and 90 degrees flexion were 31.8 degrees +/-1.2 degrees and 39.2 degrees +/-2.8 degrees , respectively. The differences between the true and measured angles were not significant. The measured angle increased by more than 10 degrees after cutting of the popliteus tendon in both 30 degrees and 90 degrees flexion. Conclusions: Using a smartphone application could be a good method of measuring knee rotation. PMID- 29172393 TI - The Meniscofemoral Ligament Mimicking a Lateral Meniscus Tear. AB - A 58-year-old male patient who had developed left knee pain with a history of trauma was referred to our hospital. Physical examination and further examination by magnetic resonance imaging revealed results that closely resemble a horizontal tear of the lateral meniscus and a tear of the medial meniscus. Arthroscopically, we found a cord-like structure originating from the posterior 1/3 portion of the lateral meniscus and passing obliquely toward the medial femoral condyle in front of the posterior cruciate ligament without a tear of the lateral meniscus. In this report, we describe a rare case of anterior meniscofemoral ligament that was clearly seen on arthroscopy and mimicked a meniscal tear, which is also known as a pseudo-tear of the meniscus.

AB - A 64-year-old marathon runner presented to our clinic with a history of worsening pain in her left knee. Following magnetic resonance imaging, the diagnosis of subchondral insufficiency fracture of the knee (SIFK) was made. A course of conservative management via bisphosphonates was initiated. The patient successfully recovered and returned to full athletic function, having recently returned to competitive marathon running. This article aims to present this unusual case of lateral compartment SIFK and summarise the literature on this uncommon condition. PMID- 29172395 TI - The Clinicopathological and Prognostic Significance of the Gross Classification of Hepatocellular Carcinoma. AB - BACKGROUND: We aimed to determine the clinicopathological significance of the gross classification of hepatocellular carcinoma (HCC) according to the Korean Liver Cancer Association (KLCA) guidelines. METHODS: A retrospective analysis was performed on 242 cases of consecutively resected solitary primary HCC between 2003 and 2012 at Seoul National University Bundang Hospital. The gross classification (vaguely nodular [VN], expanding nodular [EN], multinodular confluent [MC], nodular with perinodular extension [NP], and infiltrative [INF]) was reviewed for all cases, and were correlated with various clinicopathological features and the expression status of "stemness"-related (cytokeratin 19 [CK19], epithelial cell adhesion molecule [EpCAM]), and epithelial-mesenchymal transition (EMT)-related (urokinase plasminogen activator receptor [uPAR] and Ezrin) markers. RESULTS: Significant differences were seen in overall survival (p=.015) and disease-free survival (p = .034) according to the gross classification; INF type showed the worst prognosis while VN and EN types were more favorable. When the gross types were simplified into two groups, type 2 HCCs (MC/NP/INF) were more frequently larger and poorly differentiated, and showed more frequent microvascular and portal venous invasion, intratumoral fibrous stroma and higher pT stages compared to type 1 HCCs (EN/VN) (p<.05, all). CK19, EpCAM, uPAR, and ezrin expression was more frequently seen in type 2 HCCs (p<.05, all). Gross classification was an independent predictor of both overall and disease-free survival by multivariate analysis (overall survival: p=.030; hazard ratio, 4.118; 95% confidence interval, 1.142 to 14.844; disease-free survival: p=.016; hazard ratio, 1.617; 95% confidence interval, 1.092 to 2.394). CONCLUSIONS: The gross classification of HCC had significant prognostic value and type 2 HCCs were associated with clinicopathological features of aggressive behavior, increased expression of "stemness"- and EMT-related markers, and decreased survival. PMID- 29172397 TI - Favorable effect of corticosteroids in treating acute-on-chronic liver failure underlying chronic hepatitis B. AB - Acute-on-chronic liver failure (ACLF) occurs in the presence of a chronic liver disease or cirrhosis, and often results from exacerbation of chronic hepatitis B (CHB). The efficacy of corticosteroid treatment in ACLF patients with underlying CHB remains unclear. We report the case of a 50-year-old woman who experienced ACLF due to CHB exacerbation and was treated with a combination of corticosteroids and nucleot(s)ide analogue (NUC). The patient showed rapid decompensation due to CHB exacerbation. Three months of antiviral therapy produced no improvement in liver function. Combination therapy with corticosteroids and NUC was started, which did result in improvement of liver function. This case shows that the combined therapy of corticosteroids and NUC can be effective in treating ACLF due to CHB exacerbation. PMID- 29172396 TI - The Effect of Endoscopic Tympanoplasty on Cochlear Function. AB - OBJECTIVES: The aim of this prospective clinical study was to measure the audiologic outcomes of the patients that underwent endoscopic transcanal cartilage tympanoplasty, and to investigate the effects on cochlear function. METHODS: Thirty-three patients (33 ears) who were diagnosed with noncomplicated chronic otitis media and underwent endoscopic transcanal cartilage tympanoplasty technique were included. Pre- and postoperative first month distortion product otoacoustic emission (DPOAE) signal-to-noise ratio (SNR), bone conduction hearing levels and air bone gap (ABG) values were measured and total endoscope usage time was noted. RESULTS: Preoperative median SNR measurements at 0.5, 1, 2, and 4 kHz were 6 dB (1-11; interquartile range [IQR], 1), 6 dB (4-20; IQR, 1), 7 dB (3-26; IQR, 5) and 5.50 dB (0-9; IQR, 3), respectively. Postoperative median SNR measurements at 0.5, 1, 2, and 4 kHz were 6 dB (3-9; IQR, 1), 6 dB (2-21; IQR, 3), 7 dB (2-20; IQR, 3), and 6 dB (0-10; IQR, 7), respectively. Regarding the DPOAE measurements, there was no statistically significant difference between the SNR values of all given frequencies (P>0.05). Regarding the pure tone audiometry (PTA) measurements, bone conduction was significantly better at 0.5 and 1 kHz, postoperatively (P<0.05) and there was statistically significant difference at 2 and 4 kHz (P>0.05). Additionally, no statistically significant correlation was found between the SNR and PTA measurements and the endoscope usage time (P>0.05). CONCLUSION: We suggested that cochlear functions and sensorineural hearing remained stable after endoscopic transcanal cartilage tympanoplasty and cold light source doesn't cause significant adverse effects cochlear functions. PMID- 29172398 TI - The evaluation of cellular immune function in elderly patients with systemic lupus erythematosus. AB - Background/Aims: To evaluate cellular immune function in systemic lupus erythematosus (SLE) patients over 60 years old, the association between antinuclear antibody (ANA) titers and the ratio of CD4+ /CD8+ was analyzed in this study. The distribution of ANAs and extractable nuclear antibodies (ENAs) in a healthy elderly population was also investigated. Methods: Serum ANA titers were assayed by indirect immunofluorescence (IIF) and the CD4+ /CD8+ T-cell ratio was determined by flow cytometry in 76 SLE patients and 30 healthy control individuals. IIF of cytoplasm and nuclear and nucleolar staining were performed on samples taken from 286 healthy elderly individuals. ENA levels were determined using a strip enzyme immunoassay among patients that tested positive for ANAs. Results: ANA titers were negative in the 30 control individuals, but were positive in the 76 SLE patients. Based on ANA titers, the SLE patients were stratified to low (<= 1:320), medium (1:640 to 1:1,280), and high (>= 1:2,560) titer groups. The average CD4+ /CD8+ ratio of the SLE group was significantly lower than that of the control group. Among the 286 healthy elderly volunteers, 59 (20.63%) tested positive for ANAs. A homogeneous pattern was present in 47.46% of those 59 patients and a granule pattern in the karyoplasm was present in 33.90%. Furthermore, of the 59 patients, ENAs immunoassay was positive in 18 (30.51%); Sjogren syndrome-related antigen A (SSA)/52 kd and Sjogren syndrome antigen B (SSB)/La were the two major antibodies. Conclusions: The significantly lower CD4+ /CD8+ ratio among SLE patients over 60 years old is associated with deregulated immune responses and the development of SLE. A low ANA titer (1:160) is common in healthy elders, emphasizing the importance of considering age when determining if the evaluation of ANA titers is to be included in autoimmune disease diagnosis. PMID- 29172399 TI - Methylprednisolone versus intravenous immune globulin as an initial therapy in adult primary immune thrombocytopenia. AB - Background/Aims: Few studies have addressed whether there are differences in clinical efficacy between intravenous methylprednisolone (methyl-Pd) and intravenous immunoglobulin (IVIg) use. Methods: We retrospectively compared platelet responses and toxicities associated with these two treatments in adult patients with immune thrombocytopenia. Patients received intravenous methyl-Pd therapy followed by oral prednisolone (Pd) from 1993 to 2002 and IVIg together with oral Pd from 2003 to 2008. Results: Early response and maintenance of the response were assessed at 7 days and 6 months after treatment, respectively. Of the 87 patients enrolled, 77 (88.5%) were eligible for analysis. Early responses occurred in 30 of 39 patients (76.9%) receiving methyl-Pd versus 33 of 38 patients (86.6%) receiving IVIg (p = 0.187). The response was maintained in 28 patients (71.8%) in the methyl-Pd arm and in 23 patients (60.5%) in the IVIg arm (p = 0.187). The time to a complete response in the IVIg arm (6 days; range, 1 to 35) was shorter than that in the methyl-Pd arm (13.5 days; range, 2 to 29) (p = 0.002). Side effects were mild and tolerable in both arms. Five years after initiating treatment, 7 of 18 patients (38.9%) and five of 14 patients (35.7%) were still maintaining a response in the methyl-Pd and IVIg arms, respectively. Conclusions: These results indicate that neither the early response rate nor the long-term outcome differed between the methyl-Pd and IVIg treatments. However, IVIg induced a complete response more rapidly than did methyl-Pd. PMID- 29172400 TI - Development, validation, and application of a novel tool to measure disease related knowledge in patients with inflammatory bowel disease. AB - Background/Aims: The Crohn's and Colitis Knowledge (CCKNOW) score does not reflect updated knowledge relating to inflammatory bowel disease (IBD). The aim of this study was to develop, validate, and apply a novel tool to measure disease related knowledge in IBD patients. Methods: A questionnaire composed of 24 items regarding knowledge of IBD was developed: Inflammatory Bowel Disease Knowledge (IBD-KNOW). Discriminate ability of IBD-KNOW was validated in three occupational groups (14 doctors, 20 nurses, and 19 clerks). The CCKNOW and IBD-KNOW were administered to IBD patients. Factors affecting the level of IBD-related knowledge were analyzed. Results: The median Inflammatory Bowel Disease Knowledge (IBD-KNOW) score was significantly different among the three groups for validation (22 doctors, 20 nurses, and five clerks; p < 0.001). The IBD-KNOW showed excellent internal consistency (Cronbach alpha = 0.952) and high correlation with CCKNOW (Spearman rho = 0.827, p = 0.01). A total of 200 IBD patients (120 Crohn's disease, 80 ulcerative colitis) completed questionnaires. Multivariate analysis showed that a higher IBDKNOW score than the median was associated with hospitalization history (odds ratio [OR], 2.625; p = 0.003), high education level (OR, 2.498; p = 0.012), and information acquired from patient organization (OR, 3.305, p = 0.035). Conclusions: The IBD-KNOW demonstrated excellent test characteristics. Hospitalization history, education level, and information acquired from patient organization play an important role in correct IBD-related knowledge. PMID- 29172401 TI - Management of carbapenem-resistant Acinetobacter baumannii epidemic in an intensive care unit using multifaceted intervention strategy. AB - BACKGROUND/AIMS: We evaluated the effects of a multifaceted intervention for controlling a carbapenem-resistant Acinetobacter baumannii (CRAB) epidemic in an intensive care unit (ICU) with no restrictions on carbapenem use. METHODS: This study was conducted in a medical ICU between April 2012 and June 2016. The baseline infection control programs included surveillance cultures, contact precautions, and environmental cleaning. However, increases in the detection of CRAB isolates beginning in May 2013 led to the implementation of a new protocol, consisting of universal glove and gown use with daily chlorhexidine bathing for all patients in combination with baseline programs. The efficacy of the intervention was subjected to interrupted time series (ITS) analysis. RESULTS: The multifaceted intervention led to a decrease in the incidence of CRAB from 17.65 to 0.89 cases per 1,000 patient-days, during the study period (p < 0.001). ITS analysis revealed a significant change in the trend of CRAB incidence ( 0.413, p < 0.001). Over this same period, mean monthly use of carbapenems increased from 143.54 +/- 95.73 to 204.95 +/- 78.43 doses per 1,000 patient-days (p = 0.018). CONCLUSION: Our multifaceted intervention reduced the incidence of CRAB acquisition in an ICU where carbapenem use was not restricted. PMID- 29172402 TI - Olmesartan is not associated with the risk of enteropathy: a Korean nationwide observational cohort study. AB - Background/Aims: Olmesartan, a widely used angiotensin II receptor blocker (ARB), has been linked to sprue-like enteropathy. No cases of olmesartan-associated enteropathy have been reported in Northeast Asia. We investigated the associations between olmesartan and other ARBs and the incidence of enteropathy in Korea. Methods: Our retrospective cohort study used data from the Korean National Health Insurance Service to identify 108,559 patients (58,186 females) who were initiated on angiotensin converting enzyme inhibitors (ACEis), olmesartan, or other ARBs between January 2005 and December 2012. The incidences of enteropathy were compared among drug groups. Changes in body weight were compared after propensity score matching of patients in the ACEis and olmesartan groups. Results: Among 108,559 patients, 31 patients were diagnosed with enteropathy. The incidences were 0.73, 0.24, and 0.37 per 1,000 persons, in the ACEis, olmesartan, and other ARBs groups, respectively. Adjusted rate ratios for enteropathy were: olmesartan, 0.33 (95% confidential interval [CI], 0.10 to 1.09; p = 0.070) and other ARBs, 0.34 (95% CI, 0.14 to 0.83; p = 0.017) compared to the ACEis group after adjustment for age, sex, income level, and various comorbidities. The post hoc analysis with matched cohorts revealed that the proportion of patients with significant weight loss did not differ between the ACEis and olmesartan groups. Conclusions: Olmesartan was not associated with intestinal malabsorption or significant body weight loss in the general Korean population. Additional large-scale prospective studies of the relationship between olmesartan and the incidence of enteropathy in the Asian population are needed. PMID- 29172403 TI - Circulating renalase predicts all-cause mortality and renal outcomes in patients with advanced chronic kidney disease. AB - Background/Aims: Patients with chronic kidney disease (CKD) have been found to show markedly increased rates of end-stage renal disease, major adverse cardiovascular and cerebrovascular events (MACCEs), and mortality. Therefore, new biomarkers are required for the early detection of such clinical outcomes in patients with CKD. We aimed to determine whether the level of circulating renalase was associated with CKD progression, MACCEs, and all-cause mortality, using data from a prospective randomized controlled study, Kremezin STudy Against Renal disease progression in Korea (K-STAR; NCT 00860431). Methods: A retrospective analysis of the K-STAR data was performed including 383 patients with CKD (mean age, 56.4 years; male/female, 252/131). We measured circulating renalase levels and examined the effects of these levels on clinical outcomes. Results: The mean level of serum renalase was 75.8 +/- 34.8 MUg/mL. In the multivariable analysis, lower hemoglobin levels, higher serum creatinine levels, and diabetes mellitus were significantly associated with a higher renalase levels. Over the course of a mean follow-up period of 56 months, 25 deaths and 61 MACCEs occurred. Among 322 patients in whom these outcomes were assessed, 137 adverse renal outcomes occurred after a mean follow-up period of 27.8 months. Each 10- MUg/mL increase in serum renalase was associated with significantly greater hazards of all-cause mortality and adverse renal outcomes (hazard ratio [HR] = 1.112, p = 0.049; HR = 1.052, p = 0.045). However, serum renalase level was not associated with the rate of MACCEs in patients with CKD. Conclusions: Our results indicated that circulating renalase might be a predictor of mortality and adverse renal outcomes in patients with CKD. PMID- 29172404 TI - Small RNA sequencing profiles of mir-181 and mir-221, the most relevant microRNAs in acute myeloid leukemia. AB - Background/Aims: To evaluate and select microRNAs relevant to acute myeloid leukemia (AML) pathogenesis, we analyzed differential microRNA expression by quantitative small RNA next-generation sequencing using duplicate marrow samples from individual AML patients. Methods: For this study, we obtained paired marrow samples at two different time points (initial diagnosis and first complete remission status) in patients with AML. Bone marrow microRNAs were profiled by next-generation small RNA sequencing. Quantification of microRNA expression was performed by counting aligned reads to microRNA genes. Results: Among 38 samples (32 paired samples from 16 AML patients and 6 normal marrow controls), 27 were eligible for sequencing. Small RNA sequencing showed that 12 microRNAs were selectively expressed at higher levels in AML patients than in normal controls. Among these 12 microRNAs, mir-181, mir-221, and mir-3154 were more highly expressed at initial AML diagnosis as compared to first complete remission. Significant correlations were found between higher expression levels of mir-221, mir-146, and mir-155 and higher marrow blast counts. Conclusions: Our results demonstrate that mir-221 and mir-181 are selectively enriched in AML marrow and reflect disease activity. mir-3154 is a novel microRNA that is relevant to AML but needs further validation. PMID- 29172405 TI - Risk of malignancy in patients with rheumatoid arthritis after anti-tumor necrosis factor therapy: results from Korean National Health Insurance claims data. AB - Background/Aims: Inhibition of tumor necrosis factor (TNF) is an effective treatment for rheumatoid arthritis (RA), but safety concerns about malignancy remain. The aim of this study was to evaluate cancer risk in RA patients treated with TNF inhibitors (TNFi), based on Korean Nationwide Health Insurance claims data. Methods: Patients with seropositive RA were selected from the health insurance database containing all citizens' medical information, based on both RA diagnosis codes and medications. Between 2010 and 2014, RA patients treated with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) and TNFi were enrolled and followed up. We compared the cancer incidence between patients treated with TNFi and csDMARDs using incidence rate ratios (IRRs) after adjustment for age, gender, and observational periods. Results: Of 45,423 selected patients with seropositive RA, 2,337 were treated with TNFi and 43,086 were treated with csDMARDs. The TNFi group was younger and was followed-up for a longer duration. During the observational period, 1,732 and 49 cases of cancer were detected in patients treated with csDMARDs and TNFi, respectively. Old age and male sex were associated with cancer occurrence. Adjusted IRRs for all cancers and common cancers demonstrated that cancer incidence did not differ significantly between the TNFi group and csDMARDs group (IRR = 0.913 for all cancers, p = 0.546). Conclusions: This study revealed that cancer incidence was similar in RA patients treated with TNFi and csDMARDs. Anti-TNF therapy may be a safe therapeutic option for RA treatment, in terms of malignancy. PMID- 29172406 TI - The impact of sarcopenia on health-related quality of life in elderly people: Korean National Health and Nutrition Examination Survey. AB - Background/Aims: The purpose of the study is to investigate the associations between sarcopenia and health-related quality of life in elderly men and women in Korea. Methods: In a cross-sectional study using data from 2008 to 2011 Korean National Health and Nutrition Examination Survey, 4,937 adults aged 60 years and older who underwent a dual-energy X-ray absorptiometry scan were included in the study. Sarcopenia is defined as an appendicular skeletal muscle index of two standard deviations or more below the mean for young, healthy reference populations. The health-related quality of life was measured using the EuroQol-5 dimension questionnaire. Results: The overall prevalence of sarcopenia was 6.6% in these Korean people over the age of 60 years: 11.1% for men and 3.2% for women. Sarcopenic men tended to have lower income, lower physical activity, lower body mass index, and smaller waist circumference compared with nonsarcopenic men. Sarcopenic women tended to have higher body mass index and larger waist circumference compared with nonsarcopenic women. Sarcopenic men showed higher impairments in mobility, self-care, usual activities, and pain/discomfort compared with nonsarcopenic men. Women with sarcopenia also showed higher impairments in mobility, self-care, usual activities, and anxiety/depression compared with nonsarcopenic women. Sarcopenia showed an association with impairments in selfcare for men, and with impairments in self-care, usual activities, and anxiety/depression for women, after adjusting for other confounding factors. Conclusions: There is a significant association between sarcopenia and impaired health-related quality of life in this elderly Korean population, and these results differ between men and women. PMID- 29172407 TI - The impact of primary tumor location in patients with metastatic colorectal cancer: a Korean Cancer Study Group CO12-04 study. AB - Background/Aims: Colorectal cancer is associated with different anatomical, biological, and clinical characteristics. We determined the impact of the primary tumor location in patients with metastatic colorectal cancer (mCRC). Methods: Demographic data and clinical information were collected from 1,115 patients from the Republic of Korea, who presented with mCRC between January 2009 and December 2011, using web-based electronic case report forms. Associations between the primary tumor location and the patient's clinical characteristics were assessed, and factors inf luencing overall survival were analyzed using Cox proportional hazards regression models. Results: Of the 1,115 patients recruited to the study, 244 (21.9%) had right colon cancer, 483 (43.3%) had left colon cancer, and 388 (34.8%) had rectal cancer. Liver and lung metastases occurred more frequently in patients with left colon and rectal cancer (p = 0.005 and p = 0.006, respectively), while peritoneal and ovarian metastases occurred more frequently in patients with right and left colon cancer (p < 0.001 and p = 0.031, respectively). The median overall survival of patients with tumors originating in the right colon was significantly shorter than that of patients whose tumors had originated in the left colon or rectum (13.7 months [95% confidence interval (CI), 12.0 to 15.5] vs. 18.0 months [95% CI, 16.3 to 19.7] or 19.9 months [95% CI, 18.5 to 21.3], respectively; p = 0.003). Tumor resection, the number of metastatic sites, and primary tumor location correlated with overall survival in the univariate and multivariate analyses. Conclusions: Primary tumor location influences the metastatic sites and prognosis of patients with mCRC. PMID- 29172408 TI - A novel neurofibromatosis type 1 (NF1) mutation in a patient with NF1 and pheochromocytoma. PMID- 29172410 TI - Contraception Update: Foreword. PMID- 29172409 TI - Prevalence of goiter and associated factors among schoolchildren in northeast Ethiopia. AB - OBJECTIVES: Goiter is a major public health problem, especially in developing countries such as Ethiopia. Hence, this study aimed to assess the prevalence and associated factors of goiter among children in Waghimra Zone, northeast Ethiopia. METHODS: A cross-sectional study was conducted from April 8 to 25, 2015 in northeast Ethiopia. A multistage sampling method was used to select 454 schoolchildren. Data were collected using a pre-tested structured interviewer administered questionnaire. Children were examined for the presence or absence of goiter based on the criteria of the United Nations Children's Fund, International Council for the Control of Iodine Deficiency, and the World Health Organization. Salt samples from children's homes were tested for iodine levels using a rapid iodized salt test kit. Data were entered into EpiInfo version 7 and exported to SPSS version 20 for analysis. Bivariate and multivariate logistic regression models were fitted, and adjusted odds ratio (aOR) with 95% confidence interval (CI) were computed to determine the level of significance. RESULTS: The prevalence of goiter was 62.1% (95% CI, 57.5 to 66.5%). Being female (aOR, 3.09; 95% CI, 1.57 to 6.08), having a family history of goiter (aOR, 5.18; 95% CI, 2.43 to 11.03), and using non-iodized salt (aOR, 2.20; 95% CI, 1.12 to 4.38) were factors associated with goiter among schoolchildren. CONCLUSIONS: The prevalence of goiter was high. Being female and having a family history of goiter increased the risk of goiter in children, but using iodized salt was protective. Therefore, we recommend ensuring universal access to iodized salt and increasing the awareness of the community of the importance of iodized salt utilization. PMID- 29172411 TI - Contraception Update: Oral Contraception. AB - The oral contraceptive pill (OCP) is the most commonly used form of reversible contraception. The two types of OCPs are combination oral contraceptives (COCs), which contain estrogen and progesterone, and progestin-only pills (POPs). Both have failure rates of approximately 7.2% to 9% with typical use, and are safe for most patients. Because estrogen-containing contraceptives can increase the risk of venous thromboembolism, patients with conditions associated with a risk of cardiovascular events should not use COCs. Blood pressure level should be assessed before initiation of oral contraceptives. Noncontraceptive benefits of oral contraceptives include reduced risk of ovarian and endometrial cancers, more favorable bleeding patterns, and improvement in menstruation-related symptoms such as acne, migraine headaches, and premenstrual dysphoric disorder. OCPs can be initiated any time the physician can be reasonably certain that the patient is not pregnant. Extended cycle regimens may be preferred by some patients. After assessing need, physicians should present all methods that can be used safely using a tiered effectiveness approach. High-quality contraceptive counseling includes working collaboratively with patients to find the most effective and acceptable method for them and helping to identify factors that may assist in or hinder their ability to use the method correctly over time. PMID- 29172412 TI - Contraception Update: Intrauterine Devices. AB - Copper-containing and hormonal intrauterine devices (IUD) are long-acting, highly effective contraceptive methods. They can be used safely by nulliparous patients, adolescents, patients with history of ectopic pregnancy, and patients with risk factors for sexually transmitted infections or a history of pelvic inflammatory disease (PID). These devices can be placed safely immediately postpartum and postabortion and should be inserted when physicians can be reasonably certain that the woman is not pregnant. If a woman with an IUD is shown to be pregnant, the device should be removed if strings are visible. Bleeding and cramping after insertion can be managed with nonsteroidal anti-inflammatory drugs. Perforation is rare, but may require surgical removal of the device. If a woman with an IUD is diagnosed with PID, the device can be left in place and antibiotic treatment initiated. PMID- 29172413 TI - Contraception Update: Progestin-Only Implants and Injections. AB - Progestin-only contraception is a popular method of birth control in the United States and worldwide. Progestin-only implants and injections allow patients access to long-term contraception with simple options for reversal or removal. The implant is one of the most effective forms of contraception and there are few contraindications. Manufacturer-led training is required to become certified in insertion and removal. The most common adverse effect of the implant is a change in menstrual bleeding patterns. Little evidence has shown weight gain or decreased bone mineral density with use. The depot medroxyprogesterone acetate (DMPA) injection is used widely and is effective. Adverse effects that may limit use include changes in bleeding patterns and bone mineral density loss, which is reversible after discontinuation. The risk of weight gain with DMPA is greatest in obese adolescents and black patients. There is no significantly increased risk of cancer with either method. Both are safe for use in the postpartum period, during breastfeeding, and immediately after abortion. PMID- 29172414 TI - Contraception Update: Sterilization. AB - Female sterilization procedures include postpartum partial salpingectomy via cesarean or minilaparotomy incision, interval laparoscopic procedures, or hysteroscopic placement of microinserts. Rates of failure and serious complications are low and comparable among the various methods. A hysteroscopic procedure requires a 3-month confirmatory hysterosalpingogram before it is considered effective for contraception. Hysteroscopic sterilization has been shown to be associated with a higher reoperation rate than laparoscopic procedures. For male sterilization, vasectomy is a noninvasive and highly effective method. Vasectomy is an outpatient procedure performed under local anesthesia. The procedure requires confirmation of azoospermia with a semen analysis 8 to 16 weeks after the procedure. Patients who are considering sterilization should be counseled about all the available options and the permanent nature of such procedures. PMID- 29172415 TI - Photoresponsive and Magnetoresponsive Graphene Oxide Microcapsules Fabricated by Droplet Microfluidics. AB - Fluid compartmentalization by microencapsulation is important in scenarios where protection or controlled release of encapsulated species, or isolation of chemical transformations is the central concern. Realizing responsive encapsulation systems by incorporating functional nanomaterials is of particular interest. We report here on the development of graphene oxide microcapsules enabled by a single-step microfluidic process. Interfacial reaction of epoxide bearing graphene oxide sheets and an amine-functionalized macromolecular silicone fluid creates a chemically cross-linked film with micronscale thickness at the surface of water-in-oil droplets generated by microfluidic devices. The resulting microcapsules are monodisperse, mechanically resilient, and shape-tunable constructs. Ferrite nanoparticles are incorporated via the aqueous phase and enable microcapsule positioning by a magnetic field. We exploit the photothermal response of graphene oxide to realize microcapsules with photoresponsive release characteristics and show that the microcapsule permeability is significantly enhanced by near-IR illumination. The dual magnetic and photoresponsive characteristics, combined with the use of a single-step process employing biocompatible fluids, represent highly compelling aspects for practical applications. PMID- 29172416 TI - 808 nm Light-Triggered Thermometer-Heater Upconverting Platform Based on Nd3+ Sensitized Yolk-Shell GdOF@SiO2. AB - The realization of real-time and accurate temperature reading at subcutaneous level during the photothermal therapy (PTT) could maximally avoid the collateral damages induced by overheating effects, which remains a formidable challenge for biomedical applications. Herein, 808 nm light-driven yolk-shell GdOF:Nd3+/Yb3+/Er3+@SiO2 microcapsules were developed with thermal-sensing and heating bifunctions. Under 808 nm excitation, sensitive thermometry was implemented by monitoring thermoresponsive emission from 2H11/2/4S3/2 levels of Er3+; meanwhile, the addition of Nd3+ with rich metastable intermediate levels and the yolk-shell configuration with large specific surface area triggered efficient light-to-heat conversion via enhanced nonradiative channels. The potentiality of dual-functional samples for controlled subcutaneous photothermal treatment was validated through ex vivo experiments, and the antibacterial activity against Escherichia coli was also elaborately evaluated. Results open a general avenue for designing and developing upconverting platforms with sensitive thermal-sensing and efficient heating bifunctions, which makes a significant step toward the achievement of real-time controlled PTT. PMID- 29172417 TI - Versatile Fabrication Approach of Conductive Hydrogels via Copolymerization with Vinyl Monomers. AB - Functionalized poly(ethylene dioxythiophene) (f-PEDOT) was copolymerized with two vinyl monomers of different hydrophilicity, acrylic acid and hydroxyethyl methacrylate, to produce electroconductive hydrogels with a range of physical and electronic properties. These hydrogels not only possessed tailored physical properties, such as swelling ratios and mechanical properties, but also displayed electroactivity dependent on the chemical composition of the network. Raman spectroscopy indicated that the functional PEDOT in the hydrogels is in an oxidized form, most likely accounting for the good electrochemical response of the hydrogels observed in physiological buffer. In vitro cell studies showed that cardiac cells respond differently when seeded on hydrogel substrates with different compositions. This study presents a facile approach for the fabrication of electroconductive hydrogels with a range of properties, paving the way for scaffolds that can meet the requirements of different electroresponsive tissues. PMID- 29172418 TI - Continuous Nanoparticle Assembly by a Modulated Photo-Induced Microbubble for Fabrication of Micrometric Conductive Patterns. AB - The laser-induced microbubble technique (LIMBT) has recently been developed for micro-patterning of various materials. In this method, a laser beam is focused on a dispersion of nanoparticles leading to the formation of a microbubble due to laser heating. Convection currents around the microbubble carry nanoparticles so that they become pinned to the bubble/substrate interface. The major limitation of this technique is that for most materials, a noncontinuous deposition is formed. We show that continuous patterns can be formed by preventing the microbubble from being pinned to the deposited material. This is done by modulating the laser so that the construction and destruction of the microbubble are controlled. When the method is applied to a dispersion of Ag nanoparticles, continuous electrically conductive lines are formed. Furthermore, the line width is narrower than that achieved by the standard nonmodulated LIMBT. This approach can be applied to the direct-write fabrication of micron-size conductive patterns in electronic devices without the use of photolithography. PMID- 29172419 TI - Enhanced Electrochemical Performance by Strongly Anchoring Highly Crystalline Polyaniline on Multiwalled Carbon Nanotubes. AB - Highly crystalline polyaniline (PANI) was strongly anchored on a multiwalled carbon nanotube (MWNT) surface, slowly grown from a controlled isothermal crystallization method utilizing pi-pi interactions. The crystalline PANI particles are approximately 10-38 nm thick, and the space between them varies from near 0 to 55 nm as reaction conditions vary. The highly crystalline nanohybrid (CNH) showed electrochemical performance enhancement compared with that of neat MWNTs, PANI, and the reference hybrid synthesized from chemical polymerization. The specific capacitance (SC) of CNHs was 726 F g-1 coupled with an excellent rate capability. Moreover, the strong combination between PANI and MWNTs as well as the crystalline structure in PANI improved the bulk conductivity, the interfacial charge transportation, and the cycling stability of the CNHs. The SC value of the CNHs remained almost unchanged upon 1000 charge discharge cycles, followed by just a slight decline of 2.6% after 10 000 cycle tests. X-ray diffraction data shows the SC decline mainly resulted from the structural variation of crystalline PANI. Furthermore, the resulting CNHs showed significant electrocatalytic behavior toward H2O2 and exhibited a low detection limit of 4.4 MUM due to the enhanced electron transportation between MWNTs and PANI. The reported method opens a gateway to design high-performance MWNT/PANI hybrids for use in electrochemical sensors, fuel cells, and energy-storage related devices.

AB - We demonstrate that a poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)/diindenoperylene (PEDOT:PSS/DIP) interfacial bilayer could serve as a structural template to enable the morphological control of bulk heterojunctions (BHJs) by co-evaporation of tetraphenyldibenzoperiflanthene:fullerene (DBP:C60), which greatly improves the device performances. Especially, we show that isolated crystalline domains of C60 can be well-controlled at the nanoscale during the co evaporation. Photoluminescence spectra indicate the realization of DIP/DBP cascade energy architecture, which significantly facilitates both the energy transfer and photocurrent generation. In addition, with bias-dependent external quantum efficiency analysis, we reveal that such a cascade energy device architecture greatly suppresses the energy recombination in both carrier and exciton transfer, resulting in a high open-circuit voltage and a high fill factor. By carefully optimizing the interfacial and BHJ layers, we achieved a high-performance organic photovoltaic cell with a power conversion efficiency of 5.0 +/- 0.3%. PMID- 29172421 TI - Biomimetic Domain-Active Electrospun Scaffolds Facilitating Bone Regeneration Synergistically with Antibacterial Efficacy for Bone Defects. AB - To improve bone regeneration in oral microenvironment, we generated a novel biodegradable, antibacterial, and osteoconductive electrospun PLGA/PCL membrane as an ideal osteogenic scaffold. The novel three-layer membranes were structured with serial layers of electrospun chlorhexidine-doped-PLGA/PCL (PPC), PLGA/PCL (PP), and beta-tricalcium phosphate-doped-PLGA/PCL (PPbeta). To characterize osteoconductive properties of these membranes, MC3T3-E1 (MC) cultures were seeded onto the membranes for 14 days for evaluation of cell proliferation, morphology and gene/protein expression. In addition, MC cells were cultured onto different surfaces of the three-layer membranes, PPC layer facing MC cells (PPbeta-PP-PPC) and PPbeta layer facing MC cells (PPC-PP-PPbeta) to evaluate surface-material effects. Membrane properties and structures were evaluated. Antibacterial properties against Streptococcus mutans and Staphylococcus aureus were determined. Scanning electron microscope demonstrated smaller interfiber spaces of PPC and PPbeta-PP-PPC compared to PPbeta, PPC-PP-PPbeta, and PP. PPC and PPbeta-PP-PPC exhibited hydrophilic property. The three-layer membranes (PPC-PP PPbeta and PPbeta-PP-PPC) demonstrated significantly higher Young's modulus (94.99 +/- 4.03 MPa and 92.88 +/- 4.03 MPa) compared to PP (48.76 +/- 18.15 MPa) or PPC (7.92 +/- 3.97 MPa) (p < 0.05). No significant difference of cell proliferation was found among any groups at any time point (p > 0.05). Higher expression of integrins were detected at 12 h of cultures on PPC-PP-PPbeta compared to the controls. Promoted osteoconductive effects of PPC-PP-PPbeta were revealed by alkaline phosphatase assays and Western blot compared with the controls at 7 and 14 days. PPC, PPC-PP-PPbeta and PPbeta-PP-PPC exhibited a significantly wider antibacterial zone against the tested bacteria compared to PP and PPbeta (p < 0.05). These results suggested that the three-layer electrospun membranes demonstrated superior properties: higher strength, better cell adhesion, and promoted osteoconductive properties compared to single-layer membrane: however, antibacterial properties were exhibited in three-layer electrospun membranes and chlorhexidine-doped single-layer membrane. We concluded that the novel three-layer membranes could be used as a biocompatible scaffold for intraoral bone regeneration due to its enhanced osteoconductive activity and antibacterial effect. PMID- 29172422 TI - Deep Ultraviolet Copper(I) Thiocyanate (CuSCN) Photodetectors Based on Coplanar Nanogap Electrodes Fabricated via Adhesion Lithography. AB - Adhesion lithography (a-Lith) is a versatile fabrication technique used to produce asymmetric coplanar electrodes separated by a <15 nm nanogap. Here, we use a-Lith to fabricate deep ultraviolet (DUV) photodetectors by combining coplanar asymmetric nanogap electrode architectures (Au/Al) with solution processable wide-band-gap (3.5-3.9 eV) p-type semiconductor copper(I) thiocyanate (CuSCN). Because of the device's unique architecture, the detectors exhibit high responsivity (~79 A W-1) and photosensitivity (~720) when illuminated with a DUV range (lambdapeak = 280 nm) light-emitting diode at 220 MUW cm-2. Interestingly, the photosensitivity of the photodetectors remains fairly high (~7) even at illuminating intensities down to 0.2 MUW cm-2. The scalability of the a-Lith process combined with the unique properties of CuSCN paves the way to new forms of inexpensive, yet high-performance, photodetectors that can be manufactured on arbitrary substrate materials including plastic. PMID- 29172423 TI - Composition-Graded MoWSx Hybrids with Tailored Catalytic Activity by Bipolar Electrochemistry. AB - Among transition metal dichalcogenide (TMD)-based composites, TMD/graphene related material and bichalcogen TMD composites have been widely studied for application toward energy production via the hydrogen evolution reaction (HER). However, scarcely any literature explored the possibility of bimetallic TMD hybrids as HER electrocatalysts. The use of harmful chemicals and harsh preparation conditions in conventional syntheses also detracts from the objective of sustainable energy production. Herein, we present the conservational alternative synthesis of MoWSx via one-step bipolar electrochemical deposition. Through bipolar electrochemistry, the simultaneous fabrication of composition graded MoWSx hybrids, i.e., sulfur-deficient MoxW(1-x)S2 and MoxW(1-x)S3 (MoWSx/BPEcathodic and MoWSx/BPEanodic, respectively) under cathodic and anodic overpotentials, was achieved. The best-performing MoWSx/BPEcathodic and MoWSx/BPEanodic materials exhibited Tafel slopes of 45.7 and 50.5 mV dec-1, together with corresponding HER overpotentials of 315 and 278 mV at -10 mA cm-2. The remarkable HER activities of the composite materials were attributed to their small particle sizes, as well as the near-unity value of their surface Mo/W ratios, which resulted in increased exposed HER-active sites and differing active sites for the concurrent adsorption of protons and desorption of hydrogen gas. The excellent electrocatalytic performances achieved via the novel methodology adopted here encourage the empowerment of electrochemical deposition as the foremost fabrication approach toward functional electrocatalysts for sustainable energy generation. PMID- 29172424 TI - Solution-Processed Plasmonic-Dielectric Sunlight-Collecting Nanofilms for Solar Thermoelectric Application. AB - It is important but remains a challenge to develop solution-processed plasmonic solar thermoelectricity films on various substrates, without strictly considering hierarchical plasmonic-dielectric-metal structures, to harvest a wide range of visible to near-infrared sunlight. We simply fabricate plasmonic silica metastructure sunlight-collecting nanofilms on highly reflective Cu and Si surfaces by introducing spin coating (with an Ag and silica colloidal mixture, a spin coater, and a heating plate) and low-temperature annealing (in an oven at 200 degrees C for 1 h) processes. The approximately 250 nm thick metastructure consists of a top 60 nm thick silica layer as an antireflective film and a bottom 190 nm thick Ag nanoparticle-silica hybrid film as a sunlight harvester. The metastructure film reduces the reflectivity of Cu (>90%) and Si (25-35%) to less than 5% at visible to near-infrared frequencies. The metastructure film on the Cu sheet has an absorptance of 0.95 and a thermal emittance of 0.06, ideal for high performance sunlight absorbers. The solar thermoelectric powers of the film coated Cu and Si are 15.4 and 4.7 times those of the uncoated Cu and Si substrates, respectively. The metastructure film on Cu exhibited a similar or slightly higher performance than that of a top-class vapor-deposited commercialized absorber film on Cu, demonstrating the robustness of the present method. PMID- 29172425 TI - High-Performance Green Light-Emitting Diodes Based on MAPbBr3-Polymer Composite Films Prepared by Gas-Assisted Crystallization. AB - The morphology of perovskite films has a significant impact on luminous characteristics of perovskite light-emitting diodes (PeLEDs). To obtain a highly uniform methylammonium lead tribromide (MAPbBr3) film, a gas-assisted crystallization method is introduced with a mixed solution of MAPbBr3 precursor and polymer matrix. The ultrafast evaporation of the solvent causes a high degree of supersaturation which expedites the generation of a large number of nuclei to form a MAPbBr3-polymer composite film with full surface coverage and nano-sized grains. The addition of the polymer matrix significantly affects the optical properties and morphology of MAPbBr3 films. The PeLED made of the MAPbBr3-polymer composite film exhibits an outstanding device performance of a maximum luminance of 6800 cd.m-2 and a maximum current efficiency of 1.12 cd.A-1. Furthermore, 1 cm2 area pixel of PeLED displays full coverage of a strong green electroluminescence, implying that the high-quality perovskite film can be useful for large-area applications in perovskite-based optoelectronic devices. PMID- 29172426 TI - Diblock Copolymer PF-b-PDMAEMA as Effective Cathode Interfacial Material in Polymer Solar Cells. AB - An alcohol-soluble diblock copolymer poly[2,7-(9,9-dihexylfluorene)]15-block poly[2-(dimethylamino)ethyl methacrylate]75 (denoted as PF15-b-PDMAEMA75) was employed as the cathode interfacial layer (CIL) in p-i-n polymer solar cells (PSCs). PF15-b-PDMAEMA75 contains a conjugated rigid block and a nonconjugated flexible block grafted with polar amino groups, and it can effectively lower the work function of the Al cathode and decrease the series resistance of the devices. When applied as the CIL in PSCs based on poly[[4,8-bis[(2 ethylhexyl)oxy]benzo[1,2-b:4,5-b']dithiophene-2,6-diyl][3-fluoro-2-[(2 ethylhexy)carbonyl]thieno[3,4-b]thiophenediyl]]:[6,6]-phenyl C71 butyric acid methyl ester, the champion power conversion efficiency of 8.80% was achieved, which is slightly higher than that of the PSCs using the well-known poly[(9,9 bis(3'-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-2,7-(9,9-dioctylfluorene)] as CIL under our experimental conditions, and much better than that of PSCs using Ca as CIL. The improvement of the performance is mainly attributed to the enhanced open-circuit voltage and fill factor. To the best of our knowledge, this is the first time a diblock copolymer has been used as a CIL in PSCs, and this study may provide a novel avenue for the design and synthesis of interfacial materials for high-performance PSCs. PMID- 29172427 TI - Long-Term Effect of Steam Exposure on CO2 Capture Performance of Amine-Grafted Silica. AB - This study investigates the hydrothermal stability of triamine-grafted CO2 adsorbent based on a commercial-grade silica (CARiACT, P10). Grafting was conducted in dry and wet conditions at 85 degrees C. At optimum grafting conditions using 0.2 cm3 water and 1.5 cm3 aminosilane per gram of silica, the highest CO2 uptake of 1.93 mmol/g at 50 degrees C was obtained. This material was exposed to steam at 120 degrees C for up to 360 h. It was observed that increasing the duration of steam exposure from 3 to 24 h reduced adsorption uptake at 25 degrees C by 56%. However, the CO2 uptake reduction was much less severe at higher adsorption temperatures, reaching 21% at 50 degrees C and only 4% at 75 degrees C. Conducting steam treatment for 360 h reduced adsorption uptake at 25, 50, and 75 degrees C by 83, 61, and 26%, respectively. For this extreme steaming experiment, the decrease in CO2 uptake at all adsorption temperatures was attributed to the reduction of the sorbent average pore width, increasing diffusional mass transfer resistance. The results revealed that steam exposure did not reduce the amine loading or deactivate the amine groups; however, increasing exposure time decreased the average pore width, until partial collapse of material structure. Nevertheless, the large average pore width (21 nm) of the P10 silica led to higher hydrothermal stability of the amine-grafted sorbent compared to those with ordered pore structure supports, such as SBA-15 silica. PMID- 29172428 TI - Uniform Surface Modification of Li2ZnTi3O8 by Liquated Na2MoO4 To Boost Electrochemical Performance. AB - Poor ionic and electronic conductivities are the key issues to affect the electrochemical performance of Li2ZnTi3O8 (LZTO). In view of the water solubility, low melting point, good electrical conductivity, and wettability to LZTO, Na2MoO4 (NMO) was first selected to modify LZTO via simply mixing LZTO in NMO water solution followed by calcining the dried mixture at 750 degrees C for 5 h. The electrochemical performance of LZTO could be enhanced by adjusting the content of NMO, and the modified LZTO with 2 wt % NMO exhibited the most excellent rate capabilities (achieving lithiation capacities of 225.1, 207.2, 187.1, and 161.3 mAh g-1 at 200, 400, 800, and 1600 mA g-1, respectively) as well as outstanding long-term cycling stability (delivering a lithiation capacity of 229.0 mAh g-1 for 400 cycles at 500 mA g-1). Structure and composition characterizations together with electrochemical impedance spectra analysis demonstrate that the molten NMO at the sintering temperature of 750 degrees C is beneficial to diffuse into the LZTO lattices near the surface of LZTO particles to yield uniform modification layer, simultaneously ameliorating the electronic and ionic conductivities of LZTO, and thus is responsible for the enhanced electrochemical performance of LZTO. First-principles calculations further verify the substitution of Mo6+ for Zn2+ to realize doping in LZTO. The work provides a new route for designing uniform surface modification at low temperature, and the modification by NMO could be extended to other electrode materials to enhance the electrochemical performance. PMID- 29172429 TI - Dendritic Ternary Alloy Nanocrystals for Enhanced Electrocatalytic Oxidation Reactions. AB - Engineering the morphology and composition of multimetallic nanocrystals composed of noble and 3d transition metals has been of great interest due to its high potential to the development of high-performance catalytic materials for energy and sustainability. In the present work, we developed a facile aqueous approach for the formation of homogeneous ternary alloy nanocrystals with a dendritic shape, Pt-Pd-Cu nanodendrites, of which synthesis is hard to be achieved because of synthetic difficulties. Proper choice of stabilizer and fine control over the amount of stabilizer and reductant allowed the successful formation of Pt-Pd-Cu nanodendrites with controlled sizes and compositions. The prepared ternary alloy nanodendrites exhibited considerably improved electrocatalytic performance toward methanol and ethanol oxidation reactions compared to their binary alloy counterparts and commercial Pt and Pd catalysts, as well as to previously reported Pt- and Pd-based nanocatalysts because of synergism between their morphological and compositional characteristics. We anticipate that the present approach will be helpful to develop efficient electrocatalysis systems for practical applications. PMID- 29172430 TI - Ascorbic Acid Assisted High Performance Liquid Chromatography Mass Spectrometry Differentiation of Isomeric C-Chloro- and N-Chloro-Tyrosyl Peptides in Water. AB - We report a new method of ascorbic acid assisted high performance liquid chromatography (HPLC) with high resolution tandem mass spectrometry (HRMS/MS) for the differentiation of isomeric N-chloro (N-Cl) from phenol ring C-chloro (C-Cl) peptides produced during chlorination of water. Using the specific reductive nature of ascorbic acid, we successfully identified the N-Cl isomers and C-Cl isomer, overcoming the difficulty that, due to lack of standards, these isomers cannot be separated by HPLC-HRMS. Using the new approach, we identified 36 new chlorinated products including mono-, di-, tri-, and tetra-Cl-tyrosyl dipeptides in the reaction mixture based on retention time, accurate mass, 35Cl/37Cl isotopic pattern, and characteristic MS/MS fragments. The method was further applied to investigate competitive reactions when mixed tyrosyl dipeptides were chlorinated. Tyrosyl histidine was the most reactive tyrosyl dipeptide in the mixture. The chlorinated products formed are identical when the dipeptides are chlorinated separately or as a mixture. The formation conditions and stability of the chlorinated products were also examined. With increasing chlorine dose, the number of chlorine substituents on the tyrosyl dipeptides increased from products with one/two to three/four Cl atoms. Most of the chlorinated products are stable for up to 9 days. By chlorination of tyrosyl dipeptides spiked into raw water, we projected that chlorinated tyrosyl dipeptides can form during treatment of raw water containing tyrosyl dipeptides even at low MUg/L levels. This new method can be utilized for the discovery of a wide range of chlorinated peptide DBPs and the study of their formation and occurrence in water. PMID- 29172431 TI - A Hierarchically Modified Graphite Cathode with Au Nanoislands, Cysteamine, and Au Nanocolloids for Increased Electricity-Assisted Production of Isobutanol by Engineered Shewanella oneidensis MR-1. AB - It is necessary to understand the surface structural effects of electrodes on the bioalcohol productivity of Shewanella oneidensis MR-1, but this research area has not been deeply explored. Here, we report that the electricity-assisted isobutanol productivity of Shewanella oneidensis MR-1::pJL23 can be enhanced by sequentially modifying a graphite felt (GF) surface with Au nanoislands (Au), cysteamine (NH2), and Au nanoparticles (Au NPs). After bacteria were incubated for 50 h with the unmodified GF under various electrode potentials (vs Ag/AgCl), the bacterial isobutanol concentrations increased from 2.9 +/- 1 mg/L under no electricity supply to a maximum of 5.9 +/- 1 mg/L at -0.6 V. At this optimum electrode potential, the concentrations continued increasing to 9.1 +/- 1, 14 +/- 2, and 27 +/- 2 mg/L when the GF electrodes were modified with Au, NH2-Au, and Au NP-NH2-Au, respectively. We further studied how each surface structure affected the bacterial adsorptions, current profiles, and biofilms' electrochemical performances. In particular, these modifications induced the adsorption of elongated bacteria, with the amount dependent on the electrode structure. In the presence of electric supply, the amount of elongated bacteria further increased. We also found that the NH2-Au-GF and Au NP-NH2-Au-GF electrodes themselves could increase the concentrations to 11 +/- 0.3 and 12 +/- 2 mg/L, respectively, upon the bacterial incubation without electricity. Among the electrodes tested, the contribution of electricity to the bacterial isobutanol production was the greatest with the Au NP-NH2-Au-GF electrode. After 96 h of incubation, the concentration increased to 72 +/- 2 mg/L, which was 4.7 and 3.7 times the previously reported values obtained without and with electricity, respectively. PMID- 29172432 TI - Hybridizing Carbon Nitride Colloids with a Shell of Water-Soluble Conjugated Polymers for Tunable Full-Color Emission and Synergistic Cell Imaging. AB - We present the preparation of a new multicolor emission system constructed from two complementary conjugated materials that are highly photoluminescent, that is, phenyl-modified carbon nitride (PhCN) colloids as the core and water-soluble conjugated polymers (WSCPs) adsorbed as the shell. The fluorescence bands of the PhCN and WSCPs effectively complement each other and the overall emission can be simply adjusted to fully cover the visible light spectrum with white light emission also accessible. Photophysical insights imply that the interactions between PhCN and WSCPs preserve the binary system from emission distortion and degradation, which is essential to delicately tune the overall fluorescence bands. Notably, the continuously tunable emission color is achieved under single wavelength excitation (365 nm). This hybrid shows a synergistic permeation performance in cell imaging, that is, PhCN nanoparticles help the WSCP to enter the cells and therefore multicolor cellular imaging achieved. PMID- 29172433 TI - Atom-Thick Interlayer Made of CVD-Grown Graphene Film on Separator for Advanced Lithium-Sulfur Batteries. AB - Lithium-sulfur batteries are widely seen as a promising next-generation energy storage system owing to their ultrahigh energy density. Although extensive research efforts have tackled poor cycling performance and self-discharge, battery stability has been improved at the expense of energy density. We have developed an interlayer consisting of two-layer chemical vapor deposition (CVD) grown graphene supported by a conventional polypropylene (PP) separator. Unlike interlayers made of discrete nano-/microstructures that increase the thickness and weight of the separator, the CVD-graphene is an intact film with an area of 5 * 60 cm2 and has a thickness of ~0.6 nm and areal density of ~0.15 MUg cm-2, which are negligible to those of the PP separator. The CVD-graphene on PP separator is the thinnest and lightest interlayer to date and is able to suppress the shuttling of polysulfides and enhance the utilization of sulfur, leading to concurrently improved specific capacity, rate capability, and cycle stability and suppressed self-discharge when assembled with cathodes consisting of different sulfur/carbon composites and electrolytes either with or without LiNO3 additive. PMID- 29172434 TI - Challenges in the Development of a Thiol-Based Broad-Spectrum Inhibitor for Metallo-beta-Lactamases. AB - Pathogens, expressing metallo-beta-lactamases (MBLs), become resistant against most beta-lactam antibiotics. Besides the dragging search for new antibiotics, development of MBL inhibitors would be an alternative weapon against resistant bacterial pathogens. Inhibition of resistance enzymes could restore the antibacterial activity of beta-lactams. Various approaches to MBL inhibitors are described; among others, the promising motif of a zinc coordinating thiol moiety is very popular. Nevertheless, since the first report of a thiol-based MBL inhibitor (thiomandelic acid) in 2001, no steps in development of thiol based MBL inhibitors were reported that go beyond clinical isolate testing. In this study, we report on the synthesis and biochemical characterization of thiol-based MBL inhibitors and highlight the challenges behind the development of thiol-based compounds, which exhibit good in vitro activity toward a broad spectrum of MBLs, selectivity against human off-targets, and reasonable activity against clinical isolates. PMID- 29172435 TI - The Evolution of Chemical High-Throughput Experimentation To Address Challenging Problems in Pharmaceutical Synthesis. AB - The structural complexity of pharmaceuticals presents a significant challenge to modern catalysis. Many published methods that work well on simple substrates often fail when attempts are made to apply them to complex drug intermediates. The use of high-throughput experimentation (HTE) techniques offers a means to overcome this fundamental challenge by facilitating the rational exploration of large arrays of catalysts and reaction conditions in a time- and material efficient manner. Initial forays into the use of HTE in our laboratories for solving chemistry problems centered around screening of chiral precious-metal catalysts for homogeneous asymmetric hydrogenation. The success of these early efforts in developing efficient catalytic steps for late-stage development programs motivated the desire to increase the scope of this approach to encompass other high-value catalytic chemistries. Doing so, however, required significant advances in reactor and workflow design and automation to enable the effective assembly and agitation of arrays of heterogeneous reaction mixtures and retention of volatile solvents under a wide range of temperatures. Associated innovations in high-throughput analytical chemistry techniques greatly increased the efficiency and reliability of these methods. These evolved HTE techniques have been utilized extensively to develop highly innovative catalysis solutions to the most challenging problems in large-scale pharmaceutical synthesis. Starting with Pd- and Cu-catalyzed cross-coupling chemistry, subsequent efforts expanded to other valuable modern synthetic transformations such as chiral phase-transfer catalysis, photoredox catalysis, and C-H functionalization. As our experience and confidence in HTE techniques matured, we envisioned their application beyond problems in process chemistry to address the needs of medicinal chemists. Here the problem of reaction generality is felt most acutely, and HTE approaches should prove broadly enabling. However, the quantities of both time and starting materials available for chemistry troubleshooting in this space generally are severely limited. Adapting to these needs led us to invest in smaller predefined arrays of transformation-specific screening "kits" and push the boundaries of miniaturization in chemistry screening, culminating in the development of "nanoscale" reaction screening carried out in 1536-well plates. Grappling with the problem of generality also inspired the exploration of cheminformatics-driven HTE approaches such as the Chemistry Informer Libraries. These next-generation HTE methods promise to empower chemists to run orders of magnitude more experiments and enable "big data" informatics approaches to reaction design and troubleshooting. With these advances, HTE is poised to revolutionize how chemists across both industry and academia discover new synthetic methods, develop them into tools of broad utility, and apply them to problems of practical significance. PMID- 29172436 TI - Transparent and Flexible Surface-Enhanced Raman Scattering (SERS) Sensors Based on Gold Nanostar Arrays Embedded in Silicon Rubber Film. AB - Integration of surface-enhanced Raman scattering (SERS) sensors onto transparent and flexible substrates enables lightweight and deformable SERS sensors which can be wrapped or swabbed on various nonplanar surfaces for the efficient collection and detection of analytes on various surfaces. However, the development of transparent and flexible SERS substrates with high sensitivity is still challenging. Here, we demonstrate a transparent and flexible SERS substrate with high sensitivity based on a polydimethylsiloxane (PDMS) film embedded with gold nanostar (GNS) assemblies. The flexible SERS substrates enable conformal coverage on arbitrary surfaces, and the optical transparency allows light interaction with the underlying contact surface, thereby providing highly sensitive detection of analytes adsorbed on arbitrary metallic and dielectric surfaces which otherwise do not provide any noticeable Raman signals of analytes. In particular, when the flexible SERS substrates are covered onto metallic surfaces, the SERS enhancement is greatly improved because of the additional plasmon couplings between GNS and metal film. We achieve the detection capability of a trace amount of benzenethiol (10-8 M) and enormous SERS enhancement factor (~1.9 * 108) for flexible SERS substrates on Ag film. In addition, because of the embedded structure of GNS monolayers within the PDMS film, SERS sensors maintain the high sensitivity even after mechanical deformations of stretching, bending, and torsion for 100 cycles. The transparent and flexible SERS substrates introduced in this study are applicable to various SERS sensing applications on nonplanar surfaces, which are not achievable for hard SERS substrates. PMID- 29172437 TI - Use of Hupresin To Capture Red Blood Cell Acetylcholinesterase for Detection of Soman Exposure. AB - Toxicity from acute exposure to nerve agents and organophosphorus toxicants is due to irreversible inhibition of acetylcholinesterase (AChE) in the nervous system. AChE in red blood cells is a surrogate for AChE in the nervous system. Previously we developed an immunopurification method to enrich red blood cell AChE (RBC AChE) as a biomarker of exposure. The goal of the present work was to provide an alternative RBC AChE enrichment strategy, by binding RBC AChE to Hupresin affinity gel. AChE was solubilized from frozen RBC by addition of 1% Triton X-100. Insoluble debris was removed by centrifugation. The red, but not viscous, RBC AChE solution was loaded on a Hupresin affinity column. Hemoglobin and other proteins were washed off with 3 M NaCl, while retaining AChE bound to Hupresin. Denatured AChE was eluted with 1% trifluoroacetic acid. The same protocol was used for 20 mL of RBC AChE inhibited with a soman model compound. The acid denatured protein was digested with pepsin and analyzed by liquid chromatography tandem mass spectrometry on a 6600 Triple-TOF mass spectrometer. A targeted method identified the aged soman adduct on serine 203 in peptide FGESAGAAS. It was concluded that Hupresin can be used to enrich soman-inhibited AChE solubilized from 8 mL of frozen human erythrocytes, yielding a quantity sufficient for detecting soman exposure. PMID- 29172438 TI - 0D/2D Z-Scheme Heterojunctions of Bismuth Tantalate Quantum Dots/Ultrathin g-C3N4 Nanosheets for Highly Efficient Visible Light Photocatalytic Degradation of Antibiotics. AB - Constructing 0D/2D Z-scheme photocatalysts is a great promising path to improve photocatalytic activity by efficiently enhancing charge separation. Herein, we fabricated a visible-light-responsive Bi3TaO7 quantum dots (QDs)/g-C3N4 nanosheets (NSs) 0D/2D Z-scheme composite via a facile ultrasound method, and Bi3TaO7 QDs could be interspersed on the surface of g-C3N4 NSs uniformly. Furthermore, the strong interaction between Bi3TaO7 QDs and g-C3N4 NSs disturbed the CN heterocycles by forming C?O bonds between C atoms of the N-(C)3 group and O atoms of the Ta-O bond. The optimum composite with 20 wt % g-C3N4 NSs showed the superior photocatalytic activity for degradation of ciprofloxacin (CIP) over the composites prepared by mechanical mixing and solid-state methods, the photocatalytic efficiency of which were 4 and 12.2 times higher than those of bare Bi3TaO7 and g-C3N4. Photoluminescence (PL), time-resolved transient PL decay spectra, and photocurrent together verify that the photogenerated hole-electron pairs in this 0D/2D Z-scheme composite have been effectively separated. The enhanced photocatalytic activity of as-synthesized photocatalysts could be attributed to the synergistic effect of efficient Z-scheme charge separation, highly dispersed 0D Bi3TaO7 nanocrystals, coordinating sites of 2D g-C3N4 NSs and the strong coupling between them. This study might pave the way toward designing novel visible-light-induced 0D/2D photocatalyst systems for highly efficient degradation of antibiotics. PMID- 29172439 TI - Altered CREB Binding to Activity-Dependent Genes in Serine Racemase Deficient Mice, a Mouse Model of Schizophrenia. AB - cAMP-response-element-binding protein (CREB) is a transcription factor ubiquitously expressed in the brain that regulates neuroplasticity by modulating gene expression. The influx of calcium through N-methyl-d-aspartate receptors (NMDARs) is a well-defined mechanism that leads to the increased expression of CREB-dependent genes, including brain derived neurotrophic factor (BDNF), microRNA-132, and activity-regulated cytoskeleton-associated protein (Arc). These molecules are implicated in the pathophysiology of schizophrenia. We previously demonstrated that serine racemase knockout (SR-/-) mice, which exhibit NMDAR hypofunction due to a lack of the forebrain NMDAR co-agonist d-serine, also have reduced expression of CREB-dependent genes in the hippocampus. Using chromatin immunoprecipitation, we show here that, in SR-/- mice, there is less CREB bound to the promoter regions of BDNF, microRNA-132, and Arc. These data suggest that NMDAR hypofunction in SR-/- mice leads to reduced CREB binding on known activity dependent genes, in turn contributing to their reduced expression.

AB - A thin-layer source for the counting of polonium isotopes by alpha spectrometry can be rapidly prepared using microprecipitation with tellurium. Polonium was first coprecipitated with the reduction of tellurium by stannous chloride, followed by microfiltration onto a membrane filter for counting. This microprecipitation method is faster, cheaper, and more convenient than the traditional spontaneous deposition method, with an excellent Po recovery (>90%) under optimal conditions. The influences of several experimental parameters, including Te(IV) quantity, reaction time, and HCl molarity, were examined to determine the optimal conditions for Te microprecipitation. The decontamination factors of potential interferences from various radionuclides (Ra, Th, U, Pu, Am) for the counting of long-lived polonium isotopes (208Po, 209Po, and 210Po) were also evaluated, and the results confirmed a good selectivity on polonium by this microprecipitation method. Due to its strong resistance to high acidity up to 12 M HCl, the method would be particularly suitable for rapid determination of 210Po in acid leaching solution of solid samples.

AB - Pyramidal cells and astrocytes have differential susceptibility to oxygen-glucose deprivation and reperfusion (OGD-RP). It is known that excessive reactive oxygen species (ROS) in mitochondria initiates cell death, while glutathione (GSH) is one of the major defenses against ROS. Although it is known that astrocytes contain a higher concentration of GSH than neurons, and that astrocytes can provide neurons with GSH, we are unaware of a detailed and quantitative examination of the dynamic changes in the mitochondrial GSH system in the two cell types during OGD-RP. Here, we determined mitochondrial membrane potential and the degrees of oxidation of the mitochondrially targeted roGFP-based sensors for hydrogen peroxide (OxDP) and GSH (OxDG). We also developed a method to estimate the mitochondrial GSH (mGSH) concentration in single cells in the CA1 region of organotypic hippocampal slice cultures at several time-points during OGD-RP. We find that mitochondrial membrane potential drops in pyramidal cells during OGD while it is relatively stable in astrocytes. In both types of cell, the mitochondrial membrane potential decreases during RP. During OGD-RP, mitochondrial peroxide levels are the same. Astrocytic mGSH is more than four times higher than pyramidal cell mGSH (3.2 vs 0.7 mM). Astrocytic mGSH is drained from mitochondria during OGD, whereas in pyramidal cells it remains fairly constant. OxDGSH prior to and during OGD is lower (less oxidized) in pyramidal cells than in astrocytes, but the two nearly converge during RP. The larger changes of redox status in the GSH system in pyramidal cells than astrocytes is an upstream sign of the higher mortality of the pyramidal cells after facing an insult. The pattern of [mGSH] changes in the two cell types could be recognized as another mechanism by which astrocytes protect neurons from transient, extreme conditions.

AB - Transition metal ion doped one-dimensional (1-D) nanocrystals (NCs) have advantages of larger absorption cross sections and polarized absorption and emissions in comparison to 0-D NCs. However, direct synthesis of doped 1-D nanorods (NRs) or nanowires (NWs) has proven challenging. In this study, we report the synthesis of 1-D Mn-doped ZnSe NWs using a colloidal hot-injection method and shell passivation for core/shell NWs with tunable optical properties. Experimental results show optical properties of the NWs are controlled by the composition and thickness of the shell lattice. It was found that both the host Mn energy transfer and Mn-Mn coupling are strongly dependent on the type of alloy at the interface of doped core/shell NWs. For Mn-doped type I ZnSe/ZnS core/shell NWs, the ZnS shell passivation can enhance florescence quantum yield with little effect on the location of the incorporated Mn dopant due to the identical cationic Zn2+ site available for Mn dopants throughout the core/shell NWs. However, for Mn-doped quasi type II ZnSe/CdS NWs and ZnSe/CdS/ZnS core/shell NWs, the cation alloying (Zn1-xCdxS(e)) can lead to metal dopant migration from the core to the alloyed interface and tunable host-dopant energy transfer efficiencies and Mn-Mn coupling. As a result, a tunable dual-band emission can be achieved for the doped NWs with the cation-alloyed interface. The interfacial alloying mediated energy transfer and Mn-Mn coupling provides a method to control the optical properties of the doped 1-D core/shell NWs. PMID- 29172443 TI - Membrane Crossing and Membranotropic Activity of Cell-Penetrating Peptides: Dangerous Liaisons? AB - Living organisms have to maintain a stable balance in molecules and ions in the changing environment in which they are living, a process known as homeostasis. At the level of cells, the plasma membrane has a major role in homeostasis, since this hydrophobic film prevents passive diffusion of large and hydrophilic molecules between the extracellular and intracellular milieu. Living organisms have evolved with highly sophisticated transport systems to control exchanges across this barrier: import of nutrients and fuel essential for their survival; recognition of chemical or physical messengers allowing information interchanges with surrounding cells. Besides specialized proteins, endocytosis mechanisms at the level of the lipid bilayer can transport molecules from the outside across the cell membrane, in an energy-dependent manner. The cell membrane is highly heterogeneous in its molecular composition (tens of different lipids, proteins, polysaccharides, and combinations of these) and dynamic with bending, deformation, and elastic properties that depend on the local composition of membrane domains. Many viruses, microorganisms, and toxins exploit the plasma membrane to enter into cells. Chemists develop strategies to target the plasma membrane with molecules capable of circumventing this hydrophobic barrier, in particular to transport and deliver nonpermeable drugs in cells for biotechnological or pharmaceutical purposes. Drug delivery systems are numerous and include lipid-, sugar-, protein-, and peptide-based delivery systems, since these biomolecules generally have good biocompatibility, biodegradability, environmental sustainability, cost effectiveness, and availability. Among those, cell-penetrating peptides (CPPs), reported for the first time in the early 1990s, are attracting major interest not only as potential drug delivery systems but also at the level of fundamental research. It was indeed demonstrated very early that these peptides, which generally correspond to highly cationic sequences, can still cross the cell membrane at 4 degrees C, a temperature at which all active transport and endocytosis pathways are totally inhibited. Therefore, how these charged hydrophilic peptides cross the hydrophobic membrane barrier is of utmost interest as a pure basic and physicochemical question. In this Account, we focus on cationic cell-penetrating peptides (CPPs) and the way they cross cell membranes. We summarize the history of this field that emerged around 20 years ago. CPPs were indeed first identified as protein-transduction domains from the human immunodeficiency virus (HIV) TAT protein and the Antennapedia homeoprotein, a transcription factor from Drosophila. We highlight our contribution to the elucidation of CPP internalization pathways, in particular translocation, which implies perturbation and reorganization of the lipid bilayer, and endocytosis depending on sulfated glycosaminoglycans. We show a particular role of Trp (indole side chain) and Arg (guanidinium side chain), which are essential amino acids for CPP internalization. Interactions with the cell-surface are not only Coulombic; H-bonds and hydrophobic interactions contribute also significantly to CPP entry. The capacity of CPPs to cross cell membrane is not related to their strength of membrane binding. Finally, we present optimized methods based on mass spectrometry and fluorescence spectroscopy that allow unequivocal quantification of CPPs inside cells or bound to the outer leaflet of the membrane, and discuss some limitations of the technique of flow cytometry that we have recently highlighted. PMID- 29172444 TI - Metal-Free Cataluminescence Gas Sensor for Hydrogen Sulfide Based on Its Catalytic Oxidation on Silicon Carbide Nanocages. AB - Cataluminescence- (CTL-) based sensors are among the most attractive and effective tools for gas sensing, owing to their efficient selectivity, high sensitivity, and rapidity. As the sensing materials of CTL-based sensors, metal based catalysts easily bring about high costs and environmental pollution of heavy metals. More importantly, the long-term stability of metal-based catalysts is usually rather poor. Metal-free catalysts have unique advantages such as environmental friendliness, low costs, and long-term stability, making them promising materials for CTL-based sensors. Herein, we report the fabrication of a CTL sensor based on a metal-free catalyst. F-doped cage-like SiC was synthesized by wet chemical etching. The as-prepared products showed a rapid, stable, highly selective, and sensitive cataluminescent response to H2S. The stability of the sensor was demonstrated to be fairly good for at least 15 days. After CTL tests, F-doped cage-like SiC retained its original morphology, structure, and chemical composition. In addition, to the best of our knowledge, this is the first report of a metal-free CTL sensor. Metal-free catalysts are environmentally friendly and low in cost and exhibit long-term stability, which could open a new avenue of CTL sensing. PMID- 29172445 TI - Toward Theoretically Cycling-Stable Lithium-Sulfur Battery Using a Foldable and Compositionally Heterogeneous Cathode. AB - Rechargeable lithium-sulfur (Li-S) batteries have been expected for new generation electrical energy storages, which are attributed to their high theoretical energy density, cost effectiveness, and eco-friendliness. But Li-S batteries still have some problems for practical application, such as low sulfur utilization and dissatisfactory capacity retention. Herein, we designed and fabricated a foldable and compositionally heterogeneous three-dimensional sulfur cathode with integrated sandwich structure. The electrical conductivity of the cathode is facilitated by three different dimension carbons, in which short distance and long-distance pathways for electrons are provided by zero dimensional ketjen black (KB), one-dimensional activated carbon fiber (ACF) and two-dimensional graphene (G). The resultant three-dimensional sulfur cathode (T AKG/KB@S) with an areal sulfur loading of 2 mg cm-2 exhibits a high initial specific capacity, superior rate performance and a reversible discharge capacity of up to 726 mAh g-1 at 3.6 mA cm-2 with an inappreciable capacity fading rate of 0.0044% per cycle after 500 cycles. Moreover, the cathode with a high areal sulfur loading of 8 mg cm-2 also delivers a reversible discharge capacity of 938 mAh g-1 at 0.71 mA cm-2 with a capacity fading rate of 0.15% per cycle and a Coulombic efficiency of almost 100% after 50 cycles. PMID- 29172446 TI - A Compatible Sensitivity Enhancement Strategy for Electrochemiluminescence Immunosensors Based on the Biomimetic Melanin-Like Deposition. AB - In this work, a compatible strategy was demonstrated for the enhancement of detection sensitivity of sandwich-type electrochemiluminescence (ECL) immunosensors. The enhanced signal response was based on the combination of biomimetic melanin-like deposition with the effective ECL quenching ability of quinone-rich biopolymers. Gold nanoparticle-loaded horseradish peroxidase (HRP) was used as a catalytic label for the secondary antibodies. The intrinsic catalytic property of HRP toward hydrogen peroxide (H2O2) generates reactive oxygen species, which highly promote the autopolymerization of catecholamines. The resulting fast deposition of quinone-rich biopolymers approaching the luminophor-incorporated sensing platform achieves an obvious ECL quenching. A broad-spectrum tumor marker alpha fetoprotein (AFP) was selected as a model analyte to demonstrate the feasibility of the proposed strategy. Under optimal conditions, a very low detection limit of 0.056 pg mL-1 was obtained. Two orders of magnitude enhancement was achieved in contrast to the signal response without the step of catalytic biopolymer deposition. The combination of compatible HRP labeling with unique melanin-like deposition has potential as a universal strategy in other ECL bioassays. PMID- 29172447 TI - Change in the Crystallite Orientation of Poly(ethylene oxide)/Cellulose Nanofiber Composite Films. AB - The crystallite orientation and crystallographic domain structure of poly(ethylene oxide) (PEO) in cellulose nanofiber-incorporated (CNF-incorporated) PEO films developed for packaging materials were observed using wide-angle X-ray diffraction for different CNF filling ratios. When a CNF filling ratio of <10 wt % was used, the molecular chains in the PEO crystallite region were oriented in a direction perpendicular to the surface of the film; however, when the ratio was >50 wt %, the PEO molecular chains were oriented in a direction parallel to the surface of the film. The fiber axis of the CNFs became parallel to the surface of the PEO/CNF composite film when the filling ratio was >25 wt %. The change in the orientation of the PEO crystals occurred because increasing the amount of CNF in the composite films decreased the space in which the PEO could be crystallized. Furthermore, the hydrogen bonds between the PEO and the CNF may behave as crystallization nuclei for the PEO. Our results thus pave the way toward the development of packaging materials that are more impermeable to gases than the current materials.

PMID- 29172449 TI - EXOPLEXs: Chimeric Drug Delivery Platform from the Fusion of Cell-Derived Nanovesicles and Liposomes. AB - Cell-derived nanovesicles (CDNs) have been recently investigated as novel drug delivery systems (DDSs), due to the preservation of key features from the cell membrane of their precursor cells, which are responsible for an efficient cellular uptake by target cells. However, CDNs suffer from low drug loading efficiencies as well as challenges in functionalization compared to conventional DDS like liposomes. Here, we describe the first study proposing the fusion of CDNs with liposomes to form EXOPLEXs. We report the preservation of cell membranes from precursor cells similarly to CDNs, as well as high loading efficiencies of more than 65% with doxorubicin hydrochloride, a model chemotherapeutic drug. The doxorubicin-loaded EXOPLEXs (DOX-EXO) also demonstrated a higher in vitro cell killing effect than liposomes, while EXOPLEXs alone did not show any remarkable cytotoxicity. Taken together, these results illustrate the potential of EXOPLEXs as a novel DDS for targeted delivery of chemotherapeutics.

AB - Alpha-synuclein (alpha-SYN) is a central molecule in Parkinson's disease pathogenesis. Despite several studies, the molecular nature of endogenous alpha SYN especially in human brain samples is still not well understood due to the lack of reliable methods and the limited amount of biospecimens. Here, we introduce alpha-SYN single-molecule pull-down (alpha-SYN SiMPull) assay combined with in vivo protein crosslinking to count individual alpha-SYN protein and assess its native oligomerization states from biological samples including human postmortem brains. This powerful single-molecule assay can be highly useful in diagnostic applications using various specimens for neurodegenerative diseases including Alzheimer's disease and Parkinson's disease. PMID- 29172451 TI - Core-Corona Magnetic Nanospheres Functionalized with Zwitterionic Polymer Ionic Liquid for Highly Selective Isolation of Glycoprotein. AB - A novel zwitterionic polymer ionic liquid functionalized magnetic nanospheres, shortly as Fe3O4@PCL-PILs, is synthesized by grafting ionic liquid VimCOOHBr onto polymer epsilon-caprolactone (PCL) modified magnetic nanospheres via esterification and surface-initiated free radical polymerization. This established synthesis strategy offers the obtained magnetic nanospheres with well defined core-corona structure, compact grafting layer, favorable zwitterionic and negative-charged surface, and high magnetic susceptibility. The as-prepared Fe3O4@PCL-PILs nanospheres exhibit typical "zwitterionic hydrophilic interaction liquid chromatography (ZIC-HILIC)" behaviors toward protein binding, and selectively adsorption of glycoprotein is achieved. The adsorption capacity of the magnetic nanospheres toward Immunoglobulin G is high up to 1136.4 mg g-1, and the captured Immunoglobulin G could be efficiently recovered by using 0.5% NH3 H2O (v/v) as stripping reagent, providing a recovery of 80.5%. Fe3O4@PCL-PILs nanospheres are then employed as sorbent for the selective isolation of Immunoglobulin G from human whole blood, obtaining high-purity Immunoglobulin G as demonstrated by polyacrylamide gel electrophoresis assays. PMID- 29172452 TI - Adaption of a Solid-State Nanopore to Homogeneous DNA Organization Verification and Label-Free Molecular Analysis without Covalent Modification. AB - Recent advances have shown increasing designs of nucleic acid organizations via controlling the thermodynamics and kinetics of oligonucleotides. Nevertheless, deeper understanding and further applications of these DNA nanotechnologies are majorly hampered by the lack of effective analytical methodologies that are competent enough to investigate them. To deliver a potential solution, here we developed an innovative exploration that employed the emerging nanopore technique to characterize DNA organization at the single-molecule level and in completely homogeneous condition without covalent modification. With the help of counting and profiling the translocation-induced current drop of a DNA assembly structure passing through a conical glass nanopore (CGN), we have directly verified the formation of the individual double-helix concatemer generated from our model, hybridization chain reaction (HCR). Due to the ultrasensitivity of the nanopore technology, those concatemers that were difficult to observe on a conventional electrophoresis image were brought to light. The translocation duration time also provided the approximate length and folding information for the concatemers. These advantages were proven also applicable to structures with more sophisticated folding behaviors. Eventually, when coupling with an upstream reaction, CGN was further turned to a universal detector that was capable of even detecting other nucleic acid organization behaviors as well as targets that were unable to generate huge products. All of these results are expected to promote deeper study and applications of the nanopore technique in the field of nucleic acid nanotechnology. PMID- 29172453 TI - Sample Concentration of Charged Small Molecules and Peptides in Capillary Electrophoresis by Micelle to Cyclodextrin Stacking. AB - A stacking approach in capillary electrophoresis based on the reversal of the analytes' effective electrophoretic velocities at a dynamic stacking boundary formed between charged micelles (i.e., from long chain ionic surfactants) and neutral cyclodextrins (i.e., native alpha-, beta-, or gamma-cyclodextrin) is presented. The approach was demonstrated by the long injection of samples in a micellar solution followed by injection of a cyclodextrin solution zone, and then separation by co-electro-osmotic flow capillary zone electrophoresis. The reversal is caused by the formation of stable cyclodextrin-surfactant complexes at the boundary that significantly decreased the retention factor of the analytes in the presence of a micellar pseudostationary phase. The dynamic boundary was formed at the cyclodextrin zone as the micelles penetrated this zone. Under optimum conditions, the boundary disappears, and the stacking ends when all the micelles have electrophoretically migrated to the boundary. Cationic and anionic small molecules were enriched using oppositely charged micelles from sodium dodecyl sulfate and cetyltrimethylammonium bromide, respectively. There were 1-2 orders of concentration magnitude improvement in analyte detection, which is expected in stacking with hydrodynamic injection. The improvements in the peak signals (height/corrected area) were up to 236/445 and 101/76 for the cationic and anionic analytes tested, respectively. Linearity (r2) and repeatability (%RSD of migration time, peak height, and corrected peak area) under the chosen stacking conditions (cations/anions) were >=0.998/>=0.995 and <=3.8%/<=5.7%, respectively. The stacking approach was also implemented in the direct analysis of peptides from trypsin digested bovine serum albumin.

PMID- 29172455 TI - Characterizing the Structure-Function Relationship of a Naturally Occurring RNA Thermometer. AB - A large number of bacteria have been found to govern virulence and heat shock responses using temperature-sensing RNAs known as RNA thermometers. A prime example is the agsA thermometer known to regulate the production of the AgsA heat shock protein in Salmonella enterica using a "fourU" structural motif. Using the SHAPE-Seq RNA structure-probing method in vivo and in vitro, we found that the regulator functions by a subtle shift in equilibrium RNA structure populations that leads to a partial melting of the helix containing the ribosome binding site. We also demonstrate that binding of the ribosome to the agsA mRNA causes changes to the thermometer structure that appear to facilitate thermometer helix unwinding. These results demonstrate how subtle RNA structural changes can govern gene expression and illuminate the function of an important bacterial regulatory motif. PMID- 29172457 TI - Characterizing Deformability and Electrical Impedance of Cancer Cells in a Microfluidic Device. AB - Mechanical properties of cells, reflective of various biochemical characteristics such as gene expression and cytoskeleton, are promising label-free biomarkers for studying and characterizing cells. Electrical properties of cells, dependent on the cellular structure and content, are also label-free indicators of cell states and phenotypes. In this work, we have developed a microfluidic device that is able to simultaneously characterize the mechanical and electrical properties of individual biological cells in a high-throughput manner (>1000 cells/min). The deformability of MCF-7 breast cancer cells was characterized based on the passage time required for an individual cell to pass through a constriction smaller than the cell size. The total passage time can be divided into two components: the entry time required for a cell to deform and enter a constriction, which is dominated by the deformability of cells, and the transit time required for the fully deformed cell to travel inside the constriction, which mainly relies on the surface friction between cells and the channel wall. The two time durations for individual cells to pass through the entry region and transit region have both been investigated. In addition, undeformed cells and fully deformed cells were simultaneously characterized via electrical impedance spectroscopy technique. The combination of mechanical and electrical properties serves as a unique set of intrinsic cellular biomarkers for single-cell analysis, providing better differentiation of cellular phenotypes, which are not easily discernible via single-marker analysis. PMID- 29172458 TI - Transiently Thermoresponsive Acetal Polymers for Safe and Effective Administration of Amphotericin B as a Vaccine Adjuvant. AB - The quest for new potent and safe adjuvants with which to skew and boost the immune response of vaccines against intracellular pathogens and cancer has led to the discovery of a series of small molecules that can activate Toll-like receptors (TLRs). Whereas many small molecule TLR agonists cope with a problematic safety profile, amphotericin B (AmpB), a Food and Drug Administration approved antifungal drug, has recently been discovered to possess TLR-triggering activity. However, its poor aqueous solubility and cytotoxicity at elevated concentrations currently hampers its development as a vaccine adjuvant. We present a new class of transiently thermoresponsive polymers that, in their native state, have a phase-transition temperature below room temperature but gradually transform into fully soluble polymers through acetal hydrolysis at endosomal pH values. RAFT polymerization afforded well-defined block copolymers that self-assemble into micellar nanoparticles and efficiently encapsulate AmpB. Importantly, nanoencapsulation strongly reduced the cytotoxic effect of AmpB but maintained its TLR-triggering capacity. Studies in mice showed that AmpB-loaded nanoparticles can adjuvant an RSV vaccine candidate with almost equal potency as a highly immunogenic oil-in-water benchmark adjuvant.

PMID- 29172460 TI - N-Phenyl-2-naphthylamine as a Novel MALDI Matrix for Analysis and in Situ Imaging of Small Molecules. AB - Due to its strong ultraviolet absorption, low background interference in the small molecular range, and salt tolerance capacity, N-phenyl-2-naphthylamine (PNA) was developed as a novel matrix in the present study for analysis and imaging of small molecules by matrix-assisted laser desorption/ionization mass spectrometry time-of-fight (MALDI-TOF MS). The newly developed matrix displayed good performance in analysis of a wide range of small-molecule metabolites including free fatty acids, amino acids, peptides, antioxidants, and phospholipids. In addition, PNA-assisted LDI MS imaging of small molecules in brain tissue of rats subjected to middle cerebral artery occlusion (MCAO) revealed unique distributions and changes of 89 small-molecule metabolites including amino acids, antioxidants, free fatty acids, phospholipids, and sphingolipids in brain tissue 24 h postsurgery. Fifty-nine of the altered metabolites were identified, and all the changed metabolites were subject to relative quantitation and statistical analysis. The newly developed matrix has great potential application in the field of biomedical research. PMID- 29172459 TI - Structural Characterization of Ferrous Ion Binding to Retinal Guanylate Cyclase Activator Protein 5 from Zebrafish Photoreceptors. AB - Sensory guanylate cyclases (zGCs) in zebrafish photoreceptors are regulated by a family of guanylate cyclase activator proteins (called GCAP1-7). GCAP5 contains two nonconserved cysteine residues (Cys15 and Cys17) that could in principle bind to biologically active transition state metal ions (Zn2+ and Fe2+). Here, we present nuclear magnetic resonance (NMR) and isothermal titration calorimetry (ITC) binding analyses that demonstrate the binding of one Fe2+ ion to two GCAP5 molecules (in a 1:2 complex) with a dissociation constant in the nanomolar range. At least one other Fe2+ binds to GCAP5 with micromolar affinity that likely represents electrostatic Fe2+ binding to the EF-hand loops. The GCAP5 double mutant (C15A/C17A) lacks nanomolar binding to Fe2+, suggesting that Fe2+ at this site is ligated directly by thiolate groups of Cys15 and Cys17. Size exclusion chromatography analysis indicates that GCAP5 forms a dimer in the Fe2+-free and Fe2+-bound states. NMR structural analysis and molecular docking studies suggest that a single Fe2+ ion is chelated by thiol side chains from Cys15 and Cys17 in the GCAP5 dimer, forming an [Fe(SCys)4] complex like that observed previously in two-iron superoxide reductases. Binding of Fe2+ to GCAP5 weakens its ability to activate photoreceptor human GC-E by decreasing GC activity >10-fold. Our results indicate a strong Fe2+-induced inhibition of GC by GCAP5 and suggest that GCAP5 may serve as a redox sensor in visual phototransduction. PMID- 29172462 TI - ADP-Ribosylation, a Multifaceted Posttranslational Modification Involved in the Control of Cell Physiology in Health and Disease. AB - Posttranslational modifications (PTMs) regulate protein functions and interactions. ADP-ribosylation is a PTM, in which ADP-ribosyltransferases use nicotinamide adenine dinucleotide (NAD+) to modify target proteins with ADP ribose. This modification can occur as mono- or poly-ADP-ribosylation. The latter involves the synthesis of long ADP-ribose chains that have specific properties due to the nature of the polymer. ADP-Ribosylation is reversed by hydrolases that cleave the glycosidic bonds either between ADP-ribose units or between the protein proximal ADP-ribose and a given amino acid side chain. Here we discuss the properties of the different enzymes associated with ADP-ribosylation and the consequences of this PTM on substrates. Furthermore, the different domains that interpret either mono- or poly-ADP-ribosylation and the implications for cellular processes are described.

AB - Using nanomaterials to mimic the function of protein enzymes is an interesting idea. Many nanomaterials have a similar size as enzymes and they also possess catalytic activity. Over the past decade, a surge of nanozyme work has emerged, likely due to the advancement in the synthesis and characterization of inorganic nanoparticles. Many typical enzymatic reactions mimicking oxidases, peroxidases, laccases, superoxide dismutases, and catalases have been realized by simple metal oxide and metal nanoparticles. In addition, small inorganic catalysts have been loaded in nanoparticles to create another type of nanozyme. The applications of nanozymes in biosensor design, environmental remediation, and therapeutics have been demonstrated. In this Topical Review, we briefly summarize the current status of the field and then focus our attention on some important problems faced by the field. These topics include developing better nanozymes with higher activity, better substrate selectivity, and engineering enzyme-like active sites. For practical applications, reliable methods for bioconjugation of nanozymes with affinity ligands need to be achieved, but not at the cost of losing the activity of nanozymes. Finally, fundamental mechanistic studies are needed to rationally design nanozymes and to obtain key insights into a few model systems. PMID- 29172464 TI - Methylmercury Modulation in Amazon Rivers Linked to Basin Characteristics and Seasonal Flood-Pulse. AB - We investigated the impact of the seasonal inundation of wetlands on methylmercury (MeHg) concentration dynamics in the Amazon river system. We sampled 38 sites along the Solimoes/Amazon and Negro rivers and their tributaries during distinct phases of the annual flood-pulse. MeHg dynamics in both basins was contrasted to provide insight into the factors controlling export of MeHg to the Amazon system. The export of MeHg by rivers was substantially higher during high-water in both basins since elevated MeHg concentrations and discharge occurred during this time. MeHg concentration was positively correlated to %flooded area upstream of the sampling site in the Solimoes/Amazon Basin with the best correlation obtained using 100 km buffers instead of whole basin areas. The lower correlations obtained with the whole basin apparently reflected variable losses of MeHg exported from upstream wetlands due to demethylation, absorption, deposition, and degradation before reaching the sampling site. A similar correlation between %flooded area and MeHg concentrations was not observed in the Negro Basin probably due to the variable export of MeHg from poorly drained soils that are abundant in this basin but not consistently flooded.

PMID- 29172467 TI - The Promise of Self-Assembled 3D Supramolecular Coordination Complexes for Biomedical Applications. AB - In the supramolecular chemistry field, coordination-driven self-assembly has provided the basis for tremendous growth across many subdisciplines, spanning from fundamental investigations regarding the design and synthesis of new architectures to defining different practical applications. Within this framework, supramolecular coordination complexes (SCCs), defined as large chemical entities formed from smaller precursor building blocks of ionic metal nodes and organic multidentate ligands, resulting in intricate and well-defined supramolecular structures, hold great promise. Notably, interest in the construction of discrete 3D molecular architectures, such as those offered by SCCs, has experienced extraordinary progress because of their potential application as sensors, catalysts, probes, and containers and in basic host-guest chemistry. Despite numerous synthetic efforts and a number of inherent favorable properties, the field of 3D SCCs for biomedical applications is still in its infancy. This Viewpoint focuses on 3D SCCs, specifically metallacages and helicates, first briefly presenting the fundamentals in terms of the synthesis and characterization of their host-guest properties, followed by an overview of the possible biological applications with representative examples. Thus, emphasis will be given in particular to metallacages as drug delivery systems and to chiral helicates as DNA recognition domains. Overall, we will provide an update on the state-of-the-art literature and will define the challenges in this fascinating research area at the interface of different disciplines.

AB - Hetero-bimetallic and -trimetallic complexes were synthesized by the combination of different metallic fragments, a luminescent Re(I) species, and a bioactive Au(I) derivative. A ditopic P,N-donor ligand (L) was used as linker between both metals, affording six new bipyridine (bipy) Re(I)/Au(I) hetero-metallic complexes of the type fac-[Re(bipy)(CO)3(LAuCl)]+ (4-6) and [(fac-[Re(bipy)(CO)3(L)])2Au]3+ (7-9) after a thorough synthetic procedure. Their emission is associated with a triplet metal-to-ligand charge transfer (Re(dpi) -> bipy(pi*)) transition and red shifted in polar solvents with lifetimes in the range of nanoseconds and quantum yield values up to 12.5%. Cytotoxicity values in A549 cells of hetero-trimetallic species are almost twice that for the hetero-bimetallic (ca. 37 vs 69 MUM, respectively), being the L-Au fragment the source of the antiproliferative activity. Species 7 and 8 showed similar behavior by fluorescence microscopy, with a nonuniform cytoplasmatic distribution, a clear accumulation in single spots at the edge of the inner cell membrane as well as in areas within the nucleus. Preliminary studies suggest the DNA as one of the targets and passive diffusion as the entrance pathway. PMID- 29172470 TI - Simplifying Assays by Tableting Reagents. AB - Medical diagnostic assays provide exquisite sensitivity and precision in the diagnoses of patients. However, these technologies often require multiple steps, skilled technicians, and facilities to store heat-sensitive reagents. Here, we developed a high-throughput compression method to incorporate different assay components into color-coded tablets. With our technique, premeasured quantities of reagents can be encapsulated in compressed tablets. We show that tableting stabilizes heat-sensitive reagents and simplifies a broad range of assays, including isothermal nucleic acid amplification techniques, enzyme-based immunoassays, and microbead diagnostics. To test the clinical readiness of this tableting technology, we show the ability of tableted diagnostics for screening hepatitis B-positive patient samples. Our development simplifies complicated assays and the transportation of reagents and mitigates the need for refrigeration of reagents. This advances the use of complex assays in remote areas with limited infrastructure. PMID- 29172471 TI - Ratio of Methylmercury to Dissolved Organic Carbon in Water Explains Methylmercury Bioaccumulation Across a Latitudinal Gradient from North-Temperate to Arctic Lakes. AB - We investigated monomethylmercury (MMHg) bioaccumulation in lakes across a 30 degrees latitudinal gradient in eastern Canada to test the hypothesis that climate-related environmental conditions affect the sensitivity of Arctic lakes to atmospheric mercury contamination. Aquatic invertebrates (chironomid larvae, zooplankton) provided indicators of MMHg bioaccumulation near the base of benthic and planktonic food chains. In step with published data showing latitudinal declines in atmospheric mercury deposition in Canada, we observed lower total mercury concentrations in water and sediment of higher latitude lakes. Despite latitudinal declines of inorganic mercury exposure, MMHg bioaccumulation in aquatic invertebrates did not concomitantly decline. Arctic lakes with greater MMHg in aquatic invertebrates either had (1) higher water MMHg concentrations (reflecting ecosystem MMHg production) or (2) low water concentrations of MMHg, dissolved organic carbon (DOC), chlorophyll, and total nitrogen (reflecting lake sensitivity). The MMHg:DOC ratio of surface water was a strong predictor of lake sensitivity to mercury contamination. Bioaccumulation factors for biofilms and seston in Arctic lakes showed more efficient uptake of MMHg in low DOC systems. Environmental conditions associated with low biological production in Arctic lakes and their watersheds increased the sensitivity of lakes to MMHg. PMID- 29172472 TI - In Situ Subcellular Imaging of Copper and Zinc in Contaminated Oysters Revealed by Nanoscale Secondary Ion Mass Spectrometry. AB - Determining the in situ localization of trace elements at high lateral resolution levels in the biological system is very challenging, but critical for our understanding of metal sequestration and detoxification. Here, the cellular and subcellular distributions of Cu and Zn in contaminated oysters of Crassostrea hongkongensis were for the first time mapped using nanoscale secondary ion mass spectrometry (nanoSIMS). Three types of metal-containing cells were revealed in the gill and mantle of oysters, including Cu-specific hemocytes, Cu and Zn containing granular hemocytes, and Cu and Zn-containing calcium cells. Obvious intercellular distribution of Cu was found in the gill tissue, indicating the potential role of hemolymph in the transportation of Cu in oysters. The distribution of Cu showed a strong colocalization with sulfur and nitrogen in Cu specific hemocyte and intercellular hemolymph. In the Cu and Zn-containing granular hemocytes and calcium cells, the co-occurrence of Cu and Zn with phosphorus and calcium was also found. Different relationships of distributions between Cu/Zn and macronutrient elements (nitrogen, sulfur and phosphorus) implied the differential metal complexation in oysters. Interestingly, quantitative analysis of the ratios of 32S-/12C14N- and 31P-/12C14N- of metal deposited sites suggested the dynamic process of transfer of Cu and Zn from the metabolized protein pool to a more thermodynamically stable and detoxified form. PMID- 29172473 TI - Chemical Degradation of Polyacrylamide during Hydraulic Fracturing. AB - Polyacrylamide (PAM) based friction reducers are a primary ingredient of slickwater hydraulic fracturing fluids. Little is known regarding the fate of these polymers under downhole conditions, which could have important environmental impacts including decisions on strategies for reuse or treatment of flowback water. The objective of this study was to evaluate the chemical degradation of high molecular weight PAM, including the effects of shale, oxygen, temperature, pressure, and salinity. Data were obtained with a slickwater fracturing fluid exposed to both a shale sample collected from a Marcellus outcrop and to Marcellus core samples at high pressures/temperatures (HPT) simulating downhole conditions. Based on size exclusion chromatography analyses, the peak molecular weight of the PAM was reduced by 2 orders of magnitude, from roughly 10 MDa to 200 kDa under typical HPT fracturing conditions. The rate of degradation was independent of pressure and salinity but increased significantly at high temperatures and in the presence of oxygen dissolved in fracturing fluids. Results were consistent with a free radical chain scission mechanism, supported by measurements of sub-MUM hydroxyl radical concentrations. The shale sample adsorbed some PAM (~30%), but importantly it catalyzed the chemical degradation of PAM, likely due to dissolution of Fe2+ at low pH. These results provide the first evidence of radical-induced degradation of PAM under HPT hydraulic fracturing conditions without additional oxidative breaker. PMID- 29172474 TI - Relationship of Biodiversity with Heavy Metal Tolerance and Sorption Capacity: A Meta-Analysis Approach. AB - Microbial remediation of metals can alleviate the concerns of metal pollution in the environment. The microbial remediation, however, can be a complex process since microbial metal resistance and biodiversity can play a direct role in the bioremediation process. This study aims to understand the relationships among microbial metal resistance, biodiversity, and metal sorption capacity. Meta analyses based on 735 literature data points of minimum inhibitory concentrations (MIC) of Plantae, Bacteria, and Fungi exposed to As, Cd, Cr Cu, Ni, Pb, and Zn showed that metal resistance depends on the microbial Kingdom and the type of heavy metal and that consortia are significantly more resistant to heavy metals than pure cultures. A similar meta-analysis comparing 517 MIC values from different bacterial genera (Bacillus, Cupriavidus, Klebsiella, Ochrobactrum, Paenibacillus, Pseudomonas, and Ralstonia) confirmed that metal tolerance depends on the type of genus. Another meta-analysis with 195 studies showed that the maximum sorption capacity is influenced by microbial Kingdoms, the type of biosorbent (whether consortia or pure cultures), and the type of metal. This study also suggests that bioremediation using microbial consortia is a valid option to reduce environmental metal contaminations. PMID- 29172475 TI - Re(CO)3-Templated Synthesis of alpha-Amidinoazadi(benzopyrro)methenes. AB - alpha-Amidinoazadi(benzopyrro)methenes were synthesized using the Re(CO)3 unit as a templating agent. The products of these template reactions are six-coordinate rhenium complexes, with a facial arrangement of carbonyls, a noncoordinating anion, and a tridentate alpha-amidinoazadi(benzopyrro)methene ligand. The tridentate ligand shows the conversion of one diiminoisoindoline sp2 carbon to a sp3 carbon, which has been seen in the "helmet" and bicyclic phthalocyanines. The bidentate diiminoisoindoline fragment tilts out of the plane of coordination. Five examples of alpha-amidinoazadi(benzopyrro)methenes produced from these reactions using different nitrile solvents, including the nitrile activation of acetonitrile, propionitrile, butyronitrile, cyclohexanecarbonitrile, and benzonitrile.

PMID- 29172477 TI - Introducing NacNac-Like Bis(4,6-isopropylbenzoxazol-2-yl)methanide in s-Block Metal Coordination. AB - Within this work, the field of bulky methanides in metal coordination is exceeded by the synthesis of the versatile and promising bis(4,6-isopropylbenzoxazol-2 yl)methane (7) ligand platform. As an enhancement in this class of ligands, isopropyl (iPr) substituents as steric-demanding groups have been successfully introduced in proximity to the coordination pocket, mimicking the shielding abilities of the ubiquitous NacNac ligand scaffold to improve the steric protection of a coordinated s-block metal cation. A percent buried volume (% Vbur) calculation as well as an electronic structure analysis shades light onto the shielding and electronic abilities of the ligand in comparison to other selected methanides and diketiminates. Upon deprotonation with a variety of different group 1 and 2 metalation agents, a row of novel s-block metal complexes of the parent deprotonated monoanionic ligand 7 was obtained and structurally, as well as spectroscopically, characterized. In particular, in this context, the alkali-metal precursor complexes [Li(THF)2{(4,6-iPr-NCOC6H2)2CH}] (8) and [K{MU (4,6-iPr-NCOC6H2)2CH}]infinity (9) as well as the alkaline-earth-metal compounds [MgCl(THF)2{(4,6-iPr-NCOC6H2)2CH}] (10) and [M(THF)n{(4,6-iPr-NCOC6H2)2CH}2] [M = Mg, n = 0 (11); M = Ca, n = 1 (12); M = Sr, n = 1 (13); M = Ba, n = 1 (14)] were successfully synthesized. Especially, the latter four exhibit interesting trends in the solid state as well as in solution within the metal series. PMID- 29172478 TI - Controlled Dimerization of Mn12 Single-Molecule Magnets. AB - Controlled dimerization of Mn12 single-molecule magnets (SMMs) was achieved via a synthetic route involving a competition between bridging and terminal ligands, namely, diols and alcohols. The reaction using a 1:1 ratio of the competing ligands resulted in the isolation of a new family of covalently linked dimers of Mn12 SMMs. This is the first step toward the controlled growth of SMM oligomeric arrays. PMID- 29172479 TI - Enamine/Dienamine and Bronsted Acid Catalysis: Elusive Intermediates, Reaction Mechanisms, and Stereoinduction Modes Based on in Situ NMR Spectroscopy and Computational Studies. AB - Over the years, the field of enantioselective organocatalysis has seen unparalleled growth in the development of novel synthetic applications with respect to mechanistic investigations. Reaction optimization appeared to be rather empirical than rational. This offset between synthetic development and mechanistic understanding was and is generally due to the difficulties in detecting reactive intermediates and the inability to experimentally evaluate transition states. Thus, the first key point for mechanistic studies is detecting elusive intermediates and characterizing them in terms of their structure, stability, formation pathways, and kinetic properties. The second key point is evaluating the importance of these intermediates and their properties in the transition state. In the past 7 years, our group has addressed the problems with detecting elusive intermediates in organocatalysis by means of NMR spectroscopy and eventually theoretical calculations. Two main activation modes were extensively investigated: secondary amine catalysis and, very recently, Bronsted acid catalysis. Using these examples, we discuss potential methods to stabilize intermediates via intermolecular interactions; to elucidate their structures, formation pathways and kinetics; to change the kinetics of the reactions; and to address their relevance in transition states. The elusive enamine in proline catalyzed aldol reactions is used as an example of the stabilization of intermediates via inter- and intramolecular interactions; the determination of kinetics on its formation pathway is discussed. Classical structural characterization of intermediates is described using prolinol and prolinol ether enamines and dienamines. The Z/E dilemma for the second double bond of the dienamines shows how the kinetics of a reaction can be changed to allow for the detection of reaction intermediates. We recently started to investigate substrate catalyst complexes in the field of Bronsted acid catalysis. These studies on imine/chiral phosphoric acid complexes show that an appropriate combination of highly developed NMR and theoretical methods can provide detailed insights into the complicated structures, exchange kinetics, and H-bonding properties of chiral ion pairs. Furthermore, the merging of these structural investigations and photoisomerization even allowed the active transition state combinations to be determined for the first time on the basis of experimental data only, which is the gold standard in mechanistic investigations and was previously thought to be exclusively the domain of theoretical calculations. Thus, this Account summarizes our recent mechanistic work in the field of organocatalysis and explains the potential methods for addressing the central questions in mechanistic studies: stabilization of intermediates, elucidation of structures and formation pathways, and addressing transition state combinations experimentally. PMID- 29172480 TI - Myricetin Reduces Toxic Level of CAG Repeats RNA in Huntington's Disease (HD) and Spino Cerebellar Ataxia (SCAs). AB - Huntington's disease (HD) is a neurodegenerative disorder that is caused by abnormal expansion of CAG repeats in the HTT gene. The transcribed mutant RNA contains expanded CAG repeats that translate into a mutant huntingtin protein. This expanded CAG repeat also causes mis-splicing of pre-mRNA due to sequestration of muscle blind like-1 splicing factor (MBNL1), and thus both of these elicit the pathogenesis of HD. Targeting the onset as well as progression of HD by small molecules could be a potent therapeutic approach. We have screened a set of small molecules to target this transcript and found Myricetin, a flavonoid, as a lead molecule that interacts with the CAG motif and thus prevents the translation of mutant huntingtin protein as well as sequestration of MBNL1. Here, we report the first solution structure of the complex formed between Myricetin and RNA containing the 5'CAG/3'GAC motif. Myricetin interacts with this RNA via base stacking at the AA mismatch. Moreover, Myricetin was also found reducing the proteo-toxicity generated due to the aggregation of polyglutamine, and further, its supplementation also improves neurobehavioral deficits in the HD mouse model. Our study provides the structural and mechanistic basis of Myricetin as an effective therapeutic candidate for HD and other polyQ related disorders. PMID- 29172482 TI - Amino Terminal Copper and Nickel Binding Motif Derivatives of Ovispirin-3 Display Increased Antimicrobial Activity via Lipid Oxidation. AB - Antimicrobial peptides are short peptides secreted by the innate immune system to protect the host from pathogens. We have investigated the influence of the amino terminal copper and nickel binding (ATCUN) motif on derivatives of ovispirin-3 (OV-3), an alpha-helical peptide from the cathelicidin family, demonstrating an increased antimicrobial activity toward a broad range of bacteria, relative to OV 3, with MICs as low as 1.3 +/- 0.6 MUM. Each peptide was able to bind DNA and RNA with micromolar affinity, but did not display nuclease activity in vivo. The ATCUN OV-3 derivatives also displayed an increased membrane leakage and lipid peroxidation relative to Cu-GGH and OV-3 alone. These data suggest that the Cu ATCUN derivatives inhibit bacteria by binding to the membrane, promoting oxidative damage of the lipids, which then disrupts the bilayer, resulting in cell death. This stands in contrast to the mode of action of OV-3 alone, which permeabilizes the membrane without lipid oxidation. PMID- 29172481 TI - Fucoxanthin and Its Metabolite Fucoxanthinol Do Not Induce Browning in Human Adipocytes. AB - Rodent studies suggest that the antiobesity effects of fucoxanthin relate to activation of brown fat and conversion of white adipocytes to the brown phenotype. To evaluate the browning effect in human adipocytes, we investigated the genes involved in browning and measured the oxygen consumption rate (OCR). Data were analyzed by one way ANOVA. Relative to control, fucoxanthinol (1 MUM, 0.1 MUM, 0.01 MUM, 1 nM, 0.1 nM), the metabolite present in human plasma, stimulated lipolysis acutely (mean +/- SEM: 4.2 +/- 0.8, 3.1 +/- 0.6, 4.1 +/- 0.9, 3.8 +/- 0.7, 3.8 +/- 0.7, respectively, p < 0.01). There was no effect on OCR or the mRNA expression of UCP1, CPT-1beta, and GLUT4, the genes associated with browning of adipose tissue, when human adipocytes were treated with fucoxanthin or fucoxanthinol. -mRNA expression of PGC-1alpha, PPARalpha, PPARgamma, PDK4, FAS, and the lipolytic enzymes was not significantly altered by fucoxanthinol treatment (p > 0.05). Thus, in human adipocytes, fucoxanthin and its metabolite do not stimulate conversion of white adipocytes to the brown phenotype. PMID- 29172483 TI - Gold(I) Alkynyls Supported by Mono- and Bidentate NHC Ligands: Luminescence and Isolation of Unprecedented Ionic Complexes. AB - Reactions of NHC.HX (NHC = 1-benzyl-3-methylbenzimidazol-2-ylidene, X = Br-, PF6 ) and (AuC=CR)n (R = Ph, C3H6OH) in the presence of Cs2CO3 initially afford compounds of the general formula [(NHC)2Au]2[(RC2)2Au]X, which can be isolated by crystallization. With increased reaction time, only the expected mononuclear complexes of the type [NHCAuC=CR] are produced. The crystal structure of [(NHC)2Au]2[(PhC2)2Au]PF6 reveals an unprecedented triple-decker array upheld by a remarkably short (2.9375(7) A) unsupported Au...Au...Au contact. The mononuclear complex [NHCAuC=CPh] was found to crystallize as three distinct polymorphs and a pseudopolymorph, which depending on the intermolecular Au...Au distances emit blue, green, or yellow light. Two synthetic approaches were employed for the preparation of a series of dinuclear NHC-ligated Au(I) alkynyl complexes of the general formula [NHC-(CH2)n-NHC(AuC=CR)2], where NHC = N benzylbenzimidazol-2-ylidene, R = Ph, C3H6OH, C6H10OH, and n = 1-3. In solution, the complexes with aliphatic substituents on the alkynyl fragment are nonemissive, whereas their phenyl-bearing congeners demonstrate characteristic metal-perturbed 3[IL(C=CPh)] emission. In the solid state, a clear correlation between intermolecular aurophilic interactions and luminescence was established, including their role in the luminescent thermochromism of the phenylalkynyl complexes. The relationship between the Au...Au distance and emission energy was found to be inverse: i.e., the shorter the aurophilic contact, the higher the emission energy. We tentatively attribute this behavior to a smaller extent of excited-state distortion for a structure with a shorter Au...Au separation. PMID- 29172484 TI - Insulin-like Growth Factor 1 Analogs Clicked in the C Domain: Chemical Synthesis and Biological Activities. AB - Human insulin-like growth factor 1 (IGF-1) is a 70 amino acid protein hormone, with key impact on growth, development, and lifespan. The physiological and clinical importance of IGF-1 prompted challenging chemical and biological trials toward the development of its analogs as molecular tools for the IGF-1 receptor (IGF1-R) studies and as new therapeutics. Here, we report a new method for the total chemical synthesis of IGF-1 analogs, which entails the solid-phase synthesis of two IGF-1 precursor chains that is followed by the CuI-catalyzed azide-alkyne cycloaddition ligation and by biomimetic formation of a native pattern of disulfides. The connection of the two IGF-1 precursor chains by the triazole-containing moieties, and variation of its neighboring sequences (Arg36 and Arg37), was tolerated in IGF-1R binding and its activation. These new synthetic IGF-1 analogs are unique examples of disulfide bonds' rich proteins with intra main-chain triazole links. The methodology reported here also presents a convenient synthetic platform for the design and production of new analogs of this important human hormone with non-standard protein modifications. PMID- 29172485 TI - Systematic Engineering of Single Substitution in Zirconium Metal-Organic Frameworks toward High-Performance Catalysis. AB - Zirconium-based metal-organic frameworks (Zr-MOFs) exhibit great structural tunability and outstanding chemical stability, rendering them promising candidates for a wide range of practical applications. In this work, we synthesized a series of isostructural PCN-224 analogues functionalized by ethyl, bromo, chloro, and fluoro groups on the porphyrin unit, which allowed us to explicitly study the effects of electron-donating and electron-withdrawing substituents on catalytic performance in MOFs. Owing to the different electronic properties of ethyl, bromo, chloro, and fluoro substitutes, the molecular-level control over the chemical environment surrounding a catalytic center could be readily achieved in our MOFs. To investigate the effects of these substitutes on catalytic activity and selectivity, the oxidation of 3-methylpentane to corresponding alcohols and ketones was utilized as a model reaction. Within these five analogues of PCN-224, an extremely high turnover number of 7680 and turnover frequency of 10 240 h-1 was achieved by simply altering the substitutes on porphyrin rings. Moreover, a remarkable 99% selectivity of the tertiary alcohol over the five other possible by-products are realized. We demonstrate that this strategy can be used to efficiently screen a suitable peripheral environment around catalytic cores in MOFs for catalysis. PMID- 29172486 TI - A Stable Isotope Dilution Nanoflow Liquid Chromatography Tandem Mass Spectrometry Assay for the Simultaneous Detection and Quantification of Glyoxal-Induced DNA Cross-Linked Adducts in Leukocytes from Diabetic Patients. AB - Glyoxal (gx) is a bifunctional electrophile capable of cross-linking DNA. Although it is present in foods and from the environment, endogenous formation of glyoxal occurs through metabolism of carbohydrates and oxidation of lipids and nucleic acids. Plasma concentrations of glyoxal are elevated in in diabetes mellitus patients compared to nondiabetics. The most abundant 2' deoxyribonucleoside adducts cross-linked by glyoxal are dG-gx-dC, dG-gx-dA, and dG-gx-dG. These DNA cross-links can be mutagenic by damaging the integrity of the DNA structure. Herein, we developed a highly sensitive and specific assay for the simultaneous detection and quantification of the dG-gx-dC and dG-gx-dA cross links based on stable isotope dilution (SID) nanoflow liquid chromatography nanospray ionization tandem mass spectrometry (nanoLC-NSI/MS/MS) under the highly selected reaction monitoring mode and using a triple quadrupole mass spectrometer. The entire assay procedure involved addition of the stable isotope standards [15N5]dG-gx-dC and [15N5]dG-gx-dA as internal standards, enzyme hydrolysis to release the cross-links as nucleosides, enrichment by a reversed phase solid-phase extraction column, and nanoLC-NSI/MS/MS analysis. The detection limit is 0.19 amol for dG-gx-dC and 0.89 amol for dG-gx-dA, which is 400 and 80 times more sensitive, respectively, than capillary LC-NSI/MS/MS assay of these adducts. The lower limit of quantification was 94 and 90 amol for dG-gx-dC and dG gx-dA, respectively, which is equivalent to 0.056 and 0.065 adducts in 108 normal nucleotides in 50 MUg of DNA. In type 2 diabetes mellitus (T2DM) patients (n = 38), the levels of dG-gx-dC and dG-gx-dA in leukocyte DNA were 1.94 +/- 1.20 and 2.10 +/- 1.77 in 108 normal nucleotides, respectively, which were significantly higher than those in nondiabetics (n = 39: 0.83 +/- 0.92 and 1.05 +/- 0.99 in 108 normal nucleotides, respectively). Excluding the factor of smoking, an exogenous source of glyoxal, levels of these two cross-linked adducts were found to be significantly higher in nonsmoking T2DM patients than in nonsmoking control subjects. Furthermore, the levels of dG-gx-dC and dG-gx-dA correlated with HbA1c with statistical significance. To our best knowledge, this is the first report of the identification and quantification of glyoxal-derived cross-linked DNA adducts in human leukocyte DNA and their association with T2DM. This SID nanoLC-NSI/MS/MS assay is highly sensitive and specific and it requires only 50 MUg of leukocyte DNA isolated from 2-3 mL of blood to accurately quantify these two cross-linked adducts simultaneously. Our assay thus provides a useful biomarker for the evaluation of glyoxal-derived DNA damage. PMID- 29172487 TI - ZnO/gamma-Fe2O3 Charge Transfer Interface toward Highly Selective H2S Sensing at a Low Operating Temperature of 30 degrees C. AB - ZnO/gamma-Fe2O3 heterostructure has been deposited in the form of thin films using a single step facile electrochemical technique. Considering the unique properties of both ZnO and gamma-Fe2O3 toward the sensing of reducing gases, the concept of forming a heterostructure between them has been conceived. The structural characterization of the deposited material has been performed using X ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy, which revealed a flowerlike morphology with the coexistence of both ZnO and gamma-Fe2O3 leading to the formation of a heterostructure. The material showed excellent sensing properties toward the selective detection of H2S at room temperature (30 degrees C) among the three test gases, namely, CH4, H2S, and CO. The effect of relative humidity was also studied to have an idea about the performance of the device under a real situation. The results are promising and better than those of many commercially available sensors. The room temperature selective detection will help in facile fabrication of portable gadgets. PMID- 29172488 TI - Identification of Allosteric Modulators of Metabotropic Glutamate 7 Receptor Using Proteochemometric Modeling. AB - Proteochemometric modeling (PCM) is a computational approach that can be considered an extension of quantitative structure-activity relationship (QSAR) modeling, where a single model incorporates information for a family of targets and all the associated ligands instead of modeling activity versus one target. This is especially useful for situations where bioactivity data exists for similar proteins but is scarce for the protein of interest. Here we demonstrate the application of PCM to identify allosteric modulators of metabotropic glutamate (mGlu) receptors. Given our long-running interest in modulating mGlu receptor function we compiled a matrix of compound-target bioactivity data. Some members of the mGlu family are well explored both internally and in the public domain, while there are much fewer examples of ligands for other targets such as the mGlu7 receptor. Using a PCM approach mGlu7 receptor hits were found. In comparison to conventional single target modeling the identified hits were more diverse, had a better confirmation rate, and provide starting points for further exploration. We conclude that the robust structure-activity relationship from well explored target family members translated to better quality hits for PCM compared to virtual screening (VS) based on a single target. PMID- 29172489 TI - Ligand-Directed Reactivity in Dioxygen and Water Binding to cis-[Pd(NHC)2(eta2 O2)]. AB - Reaction of [Pd(IPr)2] (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) and O2 leads to the surprising discovery that at low temperature the initial reaction product is a highly labile peroxide complex cis-[Pd(IPr)2(eta2-O2)]. At temperatures ? -40 degrees C, cis-[Pd(IPr)2(eta2-O2)] adds a second O2 to form trans-[Pd(IPr)2(eta1-O2)2]. Squid magnetometry and EPR studies yield data that are consistent with a singlet diradical ground state with a thermally accessible triplet state for this unique bis-superoxide complex. In addition to reaction with O2, cis-[Pd(IPr)2(eta2-O2)] reacts at low temperature with H2O in methanol/ether solution to form trans-[Pd(IPr)2(OH)(OOH)]. The crystal structure of trans-[Pd(IPr)2(OOH)(OH)] is reported. Neither reaction with O2 nor reaction with H2O occurs under comparable conditions for cis-[Pd(IMes)2(eta2-O2)] (IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene). The increased reactivity of cis-[Pd(IPr)2(eta2-O2)] is attributed to the enthalpy of binding of O2 to [Pd(IPr)2] (-14.5 +/- 1.0 kcal/mol) that is approximately one-half that of [Pd(IMes)2] (-27.9 +/- 1.5 kcal/mol). Computational studies identify the cause as interligand repulsion forcing a wider C-Pd-C angle and tilting of the NHC plane in cis-[Pd(IPr)2(eta2-O2)]. Arene-arene interactions are more favorable and serve to further stabilize cis-[Pd(IMes)2(eta2-O2)]. Inclusion of dispersion effects in DFT calculations leads to improved agreement between experimental and computational enthalpies of O2 binding. A complete reaction diagram is constructed for formation of trans-[Pd(IPr)2(eta1-O2)2] and leads to the conclusion that kinetic factors inhibit formation of trans-[Pd(IMes)2(eta1-O2)2] at the low temperatures at which it is thermodynamically favored. Failure to detect the predicted T-shaped intermediate trans-[Pd(NHC)2(eta1-O2)] for either NHC = IMes or IPr is attributed to dynamic effects. A partial potential energy diagram for initial binding of O2 is constructed. A range of low-energy pathways at different angles of approach are present and blur the distinction between pure "side-on" or "end-on" trajectories for oxygen binding. PMID- 29172490 TI - Free Carrier Emergence and Onset of Electron-Phonon Coupling in Methylammonium Lead Halide Perovskite Films. AB - Sub-10 fs resolution pump-probe experiments on methylammonium lead halide perovskite films are described. Initial response to photoexcitation is assigned to localized hot excitons which dissociate to free carriers. This is attested to by band integrals of the pump-probe spectra where photoinduced bleaching rises abruptly 20 fs after photoexcitation. Later stages of spectral evolution are consistent with hot carrier cooling, during which state filling induced bleaching of interband and exciton transitions curiously more than doubles. Electron coupling to optical phonons is observed as periodic spectral modulations in the pump-probe data of both films. Fourier analysis identifies active phonons at ~100 and 300 wavenumbers pertaining to the lead-halide framework and organic cation motions, respectively. Coupling strengths estimated from the depth of these modulations are in the weak coupling limit, in agreement with values extracted from temperature dependent emission line shape analysis. These findings support free carriers in these materials existing as large polarons. Accordingly, these modes are probably not dictating the moderate carrier mobility in this material. PMID- 29172491 TI - Nonchelated Phosphoniomethylidene Complexes of Scandium and Lutetium. AB - The first phosphoniomethylidene complexes of scandium and lutetium, [LLn(CHPPh3)X] (L = [MeC(NDIPP)CHC(NDIPP)Me]-; Ln = Sc, X = Me, I, TfO; Ln = Lu, X = CH2SiMe3), have been synthesized and fully characterized. DFT calculations clearly demonstrate the presence of an allylic Ln, C, P pi-type interaction in these complexes. X-ray diffraction indicates that the scandium iodide complex has the shortest Sc-C bond length to date (2.044(5) A). These phosphoniomethylidene complexes readily convert into the ylide complexes, and the reactivity is affected by both X- anion and Ln3+ ion. The reaction of lutetium complex with imine shows a rapid insertion of imine into the Lu-C(alkylidene) bond. DFT calculations indicate that, although the bonding situation seems similar to that of the scandium analog, the strong negative charge at the alkylidene carbon is not sufficiently screened by one hydrogen in the lutetium complex because of a more ionic bonding, and therefore, the reactivity of the lutetium complex is much higher.

AB - A new semi-interpenetrating polymer network (semi-IPN) slow-release fertilizer (SISRF) with water absorbency, based on the kaolin-g-poly(acrylic acid-co-acrylic amide) (kaolin-g-P(AA-co-AM)) network and linear urea-formaldehyde oligomers (UF), was prepared by solution polymerization. Nutrients phosphorus and potassium were supplied by adding dipotassium hydrogen phosphate during the preparation process. The structure and properties of SISRF were characterized by various characterization methods. SISRF showed excellent water absorbency of 68 g g-1 in tap water. The slow-release behavior of nutrients and water-retention capacity of SISRF were also measured. Meanwhile, the swelling kinetics was well described by a pseudo-second-order kinetics model. Results suggested the formation of SISRF with simultaneously good slow-release and water-retention capacity, which was expected to apply in modern agriculture and horticulture.

AB - Hepatotoxicity is a leading cause of drug withdrawal from the market; thus, the assessment of potential drug induced liver injury (DILI) in preclinical trials is necessary. More and more research has shown that the covalent modification of drug reactive metabolites (RMs) for cellular proteins is a possible reason for DILI. Unfortunately, so far no appropriate method can be employed to evaluate this kind of DILI due to the low abundance of RM-protein adducts in complex biological samples. In this study, we proposed a mechanism-based strategy to solve this problem using human liver microsomes (HLMs) and online 2D nano-LC-MS analysis. First, RM modification patterns and potential modified AA residues are determined using HLM and model amino acids (AAs) by UHPLC-Q-TOF-MS. Then, a new online 2D-nano-LC-Q-TOF-MS method is established and applied to separate the digested modified microsomal peptides from high abundance peptides followed by identification of RM-modified proteins using Mascot, in which RM modification patterns on specific AA residues are added. Finally, the functions and relationship with hepatotoxicity of the RM-modified proteins are investigated using ingenuity pathway analysis (IPA) to predict the possible DILI. Using this strategy, 21 proteins were found to be modified by RMs of toosendanin, a hepatotoxic drug with complex structure, and some of them have been reported to be associated with hepatotoxicity. This strategy emphasizes the identification of drug RM-modified proteins in complex biological samples, and no pretreatment is required for the drugs. Consequently, it may serve as a valuable method to predict potential DILI, especially for complex compounds.

AB - An operationally simple, mild, redox-neutral method for the cross-coupling of alpha-hydroxyalkyltrifluoroborates is reported. Utilizing an Ir photocatalyst, alpha-hydroxyalkyl radicals are generated from the single-electron oxidation of the trifluoroborates, and these radicals are subsequently engaged in a nickel catalyzed C-C bond-forming reaction with aryl halides. The process is highly selective, functional group tolerant, and step economical, which allows the direct synthesis of secondary benzylic alcohol motifs. PMID- 29172495 TI - beta-Aminocarbonates in Regioselective and Ring Expansion Reactions. AB - The reactivity of beta-aminocarbonates as anisotropic electrophiles has been investigated with several phenols. Products distribution shows that the regioselectivity of the anchimerically driven alkylation reaction depends on the nucleophiles. The results suggest that in the presence of nucleophiles that are also good leaving groups, the reaction takes place under thermodynamic control favoring the attack on the most sterically hindered carbon of the cyclic aziridinium intermediate. Furthermore, when an enantiomerically pure pyrrolidine based carbonate was used, the reaction with phenols proceeds via a bicyclic aziridinium intermediate leading to the stereoselective synthesis of optically active 3-substituted piperidines via ring expansion reaction. These results were confirmed both by NMR spectroscopy and X-ray diffraction analysis. PMID- 29172496 TI - Antitubercular and Cytotoxic Chlorinated seco-Cyclohexenes from Uvaria alba. AB - Two new chlorine-containing polyoxygenated seco-cyclohexenes, albanols A (1) and B (2), along with the oxepinone metabolite grandiuvarone (3) were isolated from the endemic Philippine Annonaceae plant Uvaria alba. Both new compounds exhibited modest antitubercular activity. Compound 1 showed cytostatic activity (ranging from 1-50 MUM) against HeLa cells and weak antiproliferative activity against HUVEC and K-562 cells with GI50 values of 106 and 81 MUM, respectively. PMID- 29172497 TI - Diffusion Performance of Fertilizer Nutrient through Polymer Latex Film. AB - Matching the nutrient release rate of coated fertilizer with the nutrient uptake rate of the crop is the best way to increase the utilization efficiency of nutrients and reduce environmental pollution from the fertilizer. The diffusion property and mechanism of nutrients through the film are the theoretical basis for the product pattern design of coated fertilizers. For the coated fertilizer with a single-component nutrient, an extended solution-diffusion model was used to describe the difference of nutrient release rate, and the release rate is proportional to the permeation coefficient and the solubility of the nutrient. For the double- and triple-component fertilizer of N-K, N-P, and N-P-K, because of the interaction among nutrient molecules and ions, the release rates of different nutrients were significantly affected by the components in the composite fertilizer. Coating the single-component fertilizer (i.e., nitrogen fertilizer, phosphate fertilizer, and potash fertilizer) first and subsequently bulk blending is expected to be a promising way to adjust flexibly the nutrient release rate to meet the nutrient uptake rate of the crop. PMID- 29172498 TI - Reaction of H2 with O2 in Excited Electronic States: Reaction Pathways and Rate Constants. AB - Comprehensive quantum chemical analysis with the use of the multireference state averaged complete active space self-consistent field approach was carried out to study the reactions of H2 with O2 in a1Deltag, b1Sigmag+, c1Sigmau-, and A'3Deltau electronically excited states. The energetically favorable reaction pathways and possible intersystem crossings have been revealed. The energy barriers were refined employing the extended multiconfiguration quasi-degenerate second-order perturbation theory. It has been shown that the interaction of O2(a1Deltag) and O2(A'3Deltau) with H2 occurs through the H-abstraction process with relatively low activation barriers that resulted in the formation of the HO2 molecule in A" and A' electronic states, respectively. Meanwhile, molecular oxygen in singlet sigma states (b1Sigmag+ and c1Sigmau-) was proved to be nonreactive with respect to the molecular hydrogen. Appropriate rate constants for revealed reaction and quenching channels have been estimated using variational transition-state theory including corrections for the tunneling effect, possible nonadiabatic transitions, and anharmonicity of vibrations for transition states and reactants. It was demonstrated that the calculated reaction rate constant for the H2 + O2(a1Deltag) process is in reasonable agreement with known experimental data. The Arrhenius approximations for these processes have been proposed for the temperature range T = 300-3000 K. PMID- 29172500 TI - Construction of Vibronic Diabatic Hamiltonian for Excited-State Electron and Energy Transfer Processes. AB - Photoinduced excited-state electron and energy transfer processes are crucial in biological photoharvesting systems and organic photovoltaic devices. We discuss the construction of a diabatic vibronic Hamiltonian for the proper treatment of these processes involving the projection approach acting on both electronic wave functions and vibrational modes. In the electronic part, the wave function projection approach is used to construct the diabatic Hamiltonian in which both local excited states and charge-transfer states are included on the same footing. For the vibrational degrees of freedom, the vibronic couplings in the diabatic Hamiltonian are obtained in the basis of the pseudonormal modes localized on each monomer site by applying delocalized-to-localized mode projection. This systematic approach allows us to construct the vibronic diabatic Hamiltonian in molecular aggregates. PMID- 29172499 TI - Release Properties and Cellular Uptake in Caco-2 Cells of Size-Controlled Chitosan Nanoparticles. AB - The influences of particle size on the physicochemical, release, and cellular uptake properties of chitosan nanoparticles (CSNPs) were investigated. Ionotropic CSNPs of different sizes (200-1000 nm) loaded with two model core materials (resveratrol or coumarin-6) were prepared using tripolyphosphate and carrageenan as cross-linkers. With an increase of particle size, zeta potential (34.6 +/- 0.5 to 51.1 +/- 0.9) and entrapment efficiency (14.9 +/- 1.4 to 40.9 +/- 1.9) of the CSNPs were significantly (p < 0.05) increased and release rates were decreased. However, Caco-2 cellular uptake of CSNPs were significantly increased from 3.70 +/- 0.03 to 5.24 +/- 0.20 with an increase of particle size from 200 to 600 nm, whereas those significantly decreased from 5.24 +/- 0.20 to 4.55 +/- 0.2 for particles larger than 600 nm in transwell assay. Moreover, much the same uptake patterns were also observed in confocal microscopy and flow cytometry. Investigation of cellular uptake of CSNPs revealed positive correlations between ZP and EE and indicated the effects of complex factors of nanoparticles other than size. These results provide a better understanding of CSNPs absorption and raises the possibility of controlling alternative nanoparticle properties to enhance bioavailability.

AB - Photodynamic therapy (PDT), combining the laser and photosensitizers to kill tumor cells, has the potential to address many current medical requirements. In this study, magnetic Fe3O4 nanoparticles were first employed as cores and modified with oleic acid (OA) and 3-triethoxysilyl-1-propanamine. Then, the photosensitizers phycocyanin (PC) and hematoporphyrin monomethyl ether (HMME), which might be able to stimulate the cell release of reactive oxygen species after the irradiation of a near-infrared (NIR) laser, were grafted on the surface of such nanoparticles. Our results revealed the high-efficiency inhibition of breast cancer MCF-7 cells growing upon near-infrared irradiation both in vitro and in vivo. Furthermore, it was the synergy between the natural photosensitizers PC and the synthetic photosensitizers HMME that deeply influenced such inhibition compared to the groups that used either of these medicines alone. To utilize the combination of different photosensitive agents, our study thus provides a new strategy for breast cancer treatment.

AB - Herein we report the optimization of a series of pyrrolopyrimidine inhibitors of interleukin-1 receptor associated kinase 4 (IRAK4) using X-ray crystal structures and structure based design to identify and optimize our scaffold. Compound 28 demonstrated a favorable physicochemical and kinase selectivity profile and was identified as a promising in vivo tool with which to explore the role of IRAK4 inhibition in the treatment of mutant MYD88L265P diffuse large B-cell lymphoma (DLBCL). Compound 28 was shown to be capable of demonstrating inhibition of NF kappaB activation and growth of the ABC subtype of DLBCL cell lines in vitro at high concentrations but showed greater effects in combination with a BTK inhibitor at lower concentrations. In vivo, the combination of compound 28 and ibrutinib led to tumor regression in an ABC-DLBCL mouse model. PMID- 29172503 TI - Optogenetic Control of Endoplasmic Reticulum-Mitochondria Tethering. AB - The organelle interface emerges as a dynamic platform for a variety of biological responses. However, their study has been limited by the lack of tools to manipulate their occurrence in live cells spatiotemporally. Here, we report the development of a genetically encoded light-inducible tethering (LIT) system allowing the induction of contacts between endoplasmic reticulum (ER) and mitochondria, taking advantage of a pair of light-dependent heterodimerization called an iLID system. We demonstrate that the iLID-based LIT approach enables control of ER-mitochondria tethering with high spatiotemporal precision in various cell types including primary neurons, which will facilitate the functional study of ER-mitochondrial contacts. PMID- 29172504 TI - Effect of Microbial Interaction on Urea Metabolism in Chinese Liquor Fermentation. AB - Urea is the primary precursor of the carcinogen ethyl carbamate in fermented foods. Understanding urea metabolism is important for controlling ethyl carbamate production. Using Chinese liquor as a model system, we used metatranscriptome analysis to investigate urea metabolism in spontaneous food fermentation processes. Saccharomyces cerevisiae was dominant in gene transcription for urea biosynthesis and degradation. Lysinibacillus sphaericus was dominant for urea degradation. S. cerevisiae degraded 18% and L. sphaericus degraded 13% of urea in their corresponding single cultures, whereas they degraded 56% of urea in coculture after 12 h. Compared to single cultures, transcription of CAR1, DAL2, and argA, which are related to urea biosynthesis, decreased by 51, 36, and 69% in coculture, respectively. Transcription of DUR1 and ureA, which are related to urea degradation, increased by 227 and 70%, respectively. Thus, coexistence of the two strains promoted degradation of urea via transcriptional regulation of genes related to urea metabolism.

AB - A method for the synthesis of diversely substituted 3-fluoropyridines from two ketone components is described. The reaction involves photoredox coupling of alpha,alpha-difluoro-beta-iodoketones with silyl enol ethers catalyzed by fac Ir(ppy)3 under blue LED irradiation with subsequent one-pot condensation with ammonium acetate. Based on cyclic voltammetry studies, it was determined that alpha,alpha-difluoro-beta-iodoketones are reduced notably easier compared to 2,2,2-trifluoro-1-iodoethane, which may be ascribed to the influence of the carbonyl group. PMID- 29172506 TI - Potent Bis-Cyclometalated Iridium Photoreductants with beta-Diketiminate Ancillary Ligands. AB - In this work, we outline a strategy to prepare a class of improved visible-light photosensitizers. Bis-cyclometalated iridium complexes with electron-rich beta diketiminate (NacNac) ancillary ligands are demonstrated to be potent excited state electron donors. Evaluation of the photophysical and electrochemical properties establishes the excited-state redox potentials of the complexes, and Stern-Volmer quenching experiments inform on the kinetics of photoinduced electron transfer to the model substrates methyl viologen (MV2+) and benzophenone (BP). Compared to fac-Ir(ppy)3 (ppy = 2-phenylpyridine), widely regarded as a state-of-the-art photoreductant, the complexes we describe have excited-state redox potentials that are more potent by 300-400 mV and rates for photoinduced electron transfer that are accelerated by as much as a factor of 3. These complexes emerge as promising targets for application in photocatalytic reactions and other photochemical processes.

PMID- 29172508 TI - Low Cost, Fast Solution Synthesis of 3D Framework ZnO Nanosponges. AB - An efficient, template-free solution-chemical route to nanostructured ZnO sponges is presented: A mixture of Zn(NO3)2.6H2O, Zn(OAc)2.2H2O, and triethanolamine in methanol was evaporated to a highly viscous liquid and rapidly heated to >200 degrees C for 1-3 min to achieve highly porous, nanocrystalline sponges of ZnO. The viscous precursor concentrate obtained on evaporation in air was characterized by TG, DSC, and IR spectroscopy, and the product ZnO sponges by XRD, SEM, TEM, and IR spectroscopy. The fast reaction forming ZnO started at 140 degrees C and finished within a few seconds. Scherrer analysis of the XRD peak broadening showed average crystallite sizes of 8 to 11 nm for ZnO prepared by annealing at 200-450 degrees C (3 min), while grain growth to 134 nm was observed from 500 to 900 degrees C (3 min). The ZnO powders obtained at 200-900 degrees C had cell dimensions of a = 3.25 A and b = 5.21 A, matching the ZnO literature data well. SEM and TEM analyses showed highly porous, bread-like 3D nanostructures built by ca. 30-70 nm thick walls of ZnO crystallites of the approximate average sizes given by the XRD Scherrer analysis. It seems that the crystal growth above 450 degrees C takes place within the ZnO 3D structure obtained at lower temperatures without much sintering of the larger porous structure. PMID- 29172509 TI - Sequential Capture of O(3P) and HCN by Helium Nanodroplets: Infrared Spectroscopy and ab Initio Computations of the 3Sigma O-HCN Complex. AB - Catalytic thermal cracking of O2 is employed to dope helium droplets with O(3P) atoms. Mass spectrometry of the doped droplet beam reveals an O2 dissociation efficiency larger than 60%; approximately 26% of the droplet ensemble is doped with single oxygen atoms. Sequential capture of O(3P) and HCN leads to the production of a hydrogen-bound O-HCN complex in a 3Sigma electronic state, as determined via comparisons of experimental and theoretical rovibrational Stark spectroscopy. Ab initio computations of the three lowest lying intermolecular potential energy surfaces reveal two isomers, the hydrogen-bound (3Sigma) O-HCN complex and a nitrogen-bound (3Pi) HCN-O complex, lying 323 cm-1 higher in energy. The HCN-O to O-HCN interconversion barrier is predicted to be 42 cm-1. Consistent with this relatively small interconversion barrier, there is no experimental evidence for the production of the nitrogen-bound species upon sequential capture of O(3P) and HCN. PMID- 29172510 TI - Surrogate-Based Correlation Models in View of Real-Time Control of Ozonation of Secondary Treated Municipal Wastewater-Model Development and Dynamic Validation. AB - New robust correlation models for real-time monitoring and control of trace organic contaminant (TrOC) removal by ozonation are presented, based on UVA254 and fluorescence surrogates, and developed considering kinetic information. The abatement patterns of TrOCs had inflected shapes, controlled by the reactivity of TrOCs toward ozone and HO* radicals. These novel and generic correlation models will be of importance for WRRF operators to reduce operational costs and minimize byproduct formation. Both UVA254 and fluorescence surrogates could be used to control DeltaTrOC, although fluorescence measurements indicated a slightly better reproducibility and an enlarged control range. The generic framework was validated for several WRRFs and correlations for any compound with known kinetic information could be developed solely using the second order reaction rate constant with ozone (kO3). Two distinct reaction phases were defined for which separate linear correlations were obtained. The first was mainly ozone controlled, while the second phase was more related to HO* reactions. Furthermore, parallel factor analysis of the fluorescence spectra enabled monitoring of multiple types of organic matter with different O3 and HO* reactivity. This knowledge is of value for kinetic modeling frameworks and for achieving a better understanding of the occurring changes of organic matter during ozonation.

High reactivity and stereoselection is observed with both dienophile substrates. Structure validation was achieved by conversion of cycloadducts into known [2.2.2]diazabicyclic compounds or into crystalline derivatives suitable for X-ray analysis. The cycloadduct derived from reaction of pyrazinone and maleic anhydride underwent selective anhydride ring opening and intersected an established precursor in the synthesis of brevianamide B. PMID- 29172512 TI - Structural and Dynamical Impact of a Universal Fluorescent Nucleoside Analogue Inserted Into a DNA Duplex. AB - Recently, a 3-hydroxychromone based nucleoside 3HCnt has been developed as a highly environment-sensitive nucleoside surrogate to investigate protein-DNA interactions. When it is incorporated in DNA, the probe is up to 50-fold brighter than 2-aminopurine, the reference fluorescent nucleoside. Although the insertion of 3HCnt in DNA was previously shown to not alter the overall DNA structure, the possibility of the probe inducing local effects cannot be ruled out. Hence, a systematic structural and dynamic study is required to unveil the 3HCnt's limitations and to properly interpret the data obtained with this universal probe. Here, we investigated by NMR a 12-mer duplex, in which a central adenine was replaced by 3HCnt. The chemical shifts variations and nOe contacts revealed that the 3HCnt is well inserted in the DNA double helix with extensive stacking interactions with the neighbor base pairs. These observations are in excellent agreement with the steady-state and time-resolved fluorescence properties indicating that the 3HCnt fluorophore is protected from the solvent and does not exhibit rotational motion. The 3HCnt insertion in DNA is accompanied by the extrusion of the opposite nucleobase from the double helix. Molecular dynamics simulations using NMR-restraints demonstrated that 3HCnt fluorophore exhibits only translational dynamics. Taken together, our data showed an excellent intercalation of 3HCnt in the DNA double helix, which is accompanied by localized perturbations. This confirms 3HCnt as a highly promising tool for nucleic acid labeling and sensing. PMID- 29172513 TI - Regioselective C-H Bond Alkynylation of Carbonyl Compounds through Ir(III) Catalysis. AB - Selective C-H bond alkynylation toward modular access to material and pharmaceutical molecules is of great desire in modern organic synthesis. Reported herein is Ir(III)-catalyzed regioselective C-H alkynylation of ketones and esters, which is generally applicable for the rapid construction of molecular complexity. This protocol provides a complementary process for conventional alkyne synthesis. Further functionalization of carbonyl-derived material molecules and pharmaceuticals demonstrates the potential synthetic utility of this methodology. PMID- 29172514 TI - Thiol Reactivity toward Atomic Oxygen Generated during the Photodeoxygenation of Dibenzothiophene S-Oxide. AB - Aromatic heterocyclic oxides, such as dibenzothiophene S-oxide (DBTO), have been suggested to release ground state atomic oxygen [O(3P)] upon irradiation, and as such, they have been used to create a condensed phase reactivity profile for O(3P). However, thiols, which are highly reactive with O(3P) in the gas phase, were not previously investigated. An earlier study of O(3P) with proteins in solution indicated a preference for thiols. A further investigation of the apparent thiophilicity provided the subject for this study. DBTO was employed as a putative O(3P)-precursor. However, the effective rate of O(3P) formation was found to be dependent on reactant concentrations in certain cases. All reactants were found to increase the rate of deoxygenation to some extent, but in the presence of reactants containing an alcohol linked to a reactive functional group, deoxygenation occurred substantially more rapidly. The rate enhancement was quantified and attributed to the reaction of activated O atom within the solvent cage prior to escape into the bulk solution. Through competition experiments, the relative rate constants of O(3P) with thiols and other functional groups were found. A small preference for primary thiols was observed over other thiols, sulfides, and alkenes. A much larger preference was observed for thiols, sulfides, and alkenes over aromatic groups. In summary, DBTO was successfully used as an O(3P)-precursor, and the thiophilicity of O(3P) was confirmed and quantified. PMID- 29172515 TI - Understanding the Inhibiting Effect of Small-Molecule Hydrogen Bond Donors on the Solubility of Cellulose in Tetrabutylammonium Acetate/DMSO. AB - Certain ionic liquids are powerful cellulose solvents, but tend to be less effective when small-molecule hydrogen bond donors are present. This is generally attributed to competition with cellulose for hydrogen bonding opportunities to the anion of the ionic liquid. We show that the solubility of cellulose in dimethyl sulfoxide solutions of tetrabutylammonium acetate is less strongly affected by water than by ethanol on a molar basis, contrary to what can be expected based on hydrogen bond stoichiometry. Molecular dynamics simulations indicate that the higher tolerance to water is due to water-cellulose interactions that improves solvation of cellulose and, thereby, marginally favors dissolution. Through Kirkwood-Buff theory we show that water, but not ethanol, improves the solvent quality of DMSO and partly compensates for the loss of acetate-cellulose hydrogen bonds. PMID- 29172516 TI - Improvement of Human-Oral-Epithelial-Barrier Function and of Tight Junctions by Micronutrients. AB - The oral epithelium represents a major interface between an organism and its external environment. Improving this barrier at the molecular level can provide an organism added protection from microbial-based diseases. Barrier function of the Gie-3B11-human-gingival-epithelial-cell-culture model is enhanced by the micronutrients zinc, quercetin, retinoic acid, and acetyl-11-keto-beta-boswellic acid, as observed by a concentration-dependent increase in transepithelial electrical resistance and a decrease in transepithelial 14C-d-mannitol permeability. With this improvement of tight-junction (TJ)-barrier function (reduced leak) comes a pattern of micronutrient-induced changes in TJ claudin abundance that is specific to each individual micronutrient, along with changes in claudin subcellular localization. These micronutrients were effective not only when administered to both cell surfaces simultaneously but also when administered to the apical surface alone, the surface to which the micronutrients would be presented in routine clinical use. The biomedical implications of micronutrient enhancement of the oral-epithelial barrier are discussed. PMID- 29172517 TI - Influence of Multiple Environmental Factors on Organic Matter Chlorination in Podsol Soil. AB - Natural chlorination of organic matter is common in soils. The abundance of chlorinated organic compounds frequently exceeds chloride in surface soils, and the ability to chlorinate soil organic matter (SOM) appears widespread among microorganisms. Yet, the environmental control of chlorination is unclear. Laboratory incubations with 36Cl as a Cl tracer were performed to test how combinations of environmental factors, including levels of soil moisture, nitrate, chloride, and labile organic carbon, influenced chlorination of SOM from a boreal forest. Total chlorination was hampered by addition of nitrate or by nitrate in combination with water but enhanced by addition of chloride or most additions including labile organic matter (glucose and maltose). The greatest chlorination was observed after 15 days when nitrate and water were added together with labile organic matter. The effect that labile organic matter strongly stimulated the chlorination rates was confirmed by a second independent experiment showing higher stimulation at increased availability of labile organic matter. Our results highlight cause-effect links between chlorination and the studied environmental variables in podsol soil-with consistent stimulation by labile organic matter that did overrule the negative effects of nitrate. PMID- 29172519 TI - xMaP-An Interpretable Alignment-Free Four-Dimensional Quantitative Structure Activity Relationship Technique Based on Molecular Surface Properties and Conformer Ensembles. AB - A novel alignment-free molecular descriptor called xMaP (flexible MaP descriptor) is introduced. The descriptor is the advancement of the previously published translationally and rotationally invariant three-dimensional (3D) descriptor MaP (mapping property distributions onto the molecular surface) to the fourth dimension (4D). In addition to MaP, xMaP is independent of the chosen starting conformation of the encoded molecules and is therefore entirely alignment-free. This is achieved by using ensembles of conformers, which are generated by conformational searches. This step of the procedure is similar to Hopfinger's 4D quantitative structure-activity relationship (QSAR). A five-step procedure is used to compute the xMaP descriptor. First, a conformational search for each molecule is carried out. Next, for each of the conformers an approximation to the molecular surface with equally distributed surface points is computed. Third, molecular properties are projected onto this surface. Fourth, areas of identical properties are clustered to so-called patches. Fifth, the spatial distribution of the patches is converted into an alignment-free descriptor that is based on the entire conformer ensemble. The resulting descriptor can be interpreted by superimposing the most important descriptor variables and the molecules of the data set. The most important descriptor variables are identified with chemometric regression tools. The novel descriptor was applied to several benchmark data sets and was compared to other descriptors and QSAR techniques comprising a binary fingerprint, a topological pharmacophore descriptor (Cats2D), and the field-based 3D-QSAR technique GRID/PLS which is alignment-dependent. The use of conformer ensembles renders xMaP very robust. It turns out that xMaP performs very well on (almost) all data sets and that the statistical results are comparable to GRID/PLS. In addition to that, xMaP can also be used to efficiently visualize the derived quantitative structure-activity relationships. PMID- 29172518 TI - Ergot Alkaloid Biosynthesis in the Maize (Zea mays) Ergot Fungus Claviceps gigantea. AB - Biosynthesis of the dihydrogenated forms of ergot alkaloids is of interest because many of the ergot alkaloids used as pharmaceuticals may be derived from dihydrolysergic acid (DHLA) or its precursor dihydrolysergol. The maize (Zea mays) ergot pathogen Claviceps gigantea has been reported to produce dihydrolysergol, a hydroxylated derivative of the common ergot alkaloid festuclavine. We hypothesized expression of C. gigantea cloA in a festuclavine accumulating mutant of the fungus Neosartorya fumigata would yield dihydrolysergol because the P450 monooxygenase CloA from other fungi performs similar oxidation reactions. We engineered such a strain, and high performance liquid chromatography and liquid chromatography-mass spectrometry analyses demonstrated the modified strain produced DHLA, the fully oxidized product of dihydrolysergol. Accumulation of high concentrations of DHLA in field-collected C. gigantea sclerotia and discovery of a mutation in the gene lpsA, downstream from DHLA formation, supported our finding that DHLA rather than dihydrolysergol is the end product of the C. gigantea pathway.

AB - A component of the neurotoxicity of the beta amyloid peptide (Abeta) of Alzheimer's disease is its ability to generate superoxide, hydrogen peroxide, and hydroxyl radicals by reaction of its reduced copper complex Abeta/Cu+ with molecular oxygen. The objective of the present work was to devise compounds, L, that could remove Cu+ from Abeta/Cu+, with the property that L/Cu+ itself would not be capable of reducing O2 or hydrogen peroxide. We show by density functional calculations that several pincer-type compounds with two imidazole rings and a sulfur or nitrogen have the desired combination of Cu+ binding affinity and Cu2+ reduction potential.

AB - Fermentation of soybean is a process in which soy proteins are broken down into small peptides to exert various physiological functions beyond their nutritional value and to improve food source bioactive components responsible for health benefits. Enzymatic hydrolysis could speed up the degradation of proteins during fermentation of soybean, thus resulting in higher peptide production. In the present study, fermented soy meal (fermented with Bacillus subtilis from Douchi) was hydrolyzed by thermolysin, and the water extraction was then separated into four fractions using ultrafiltration membranes. Their vasorelaxation activities were screened, and the most potent fraction was further isolated and purified to obtain four peptides. Briefly, three peptides exerted a dose-dependent vasorelaxation (0.01-4.10 MUM) in the phenylephrine preconstricted thoracic aorta ring of Sprague-Dawley rat (relaxation actions were all endothelium-independent), while one peptide induced vasoconstriction. Furthermore, an independent causal relationship between vasorelaxation and angiotensin converting enzyme (ACE) inhibition activities was found. PMID- 29172522 TI - Small-Angle X-ray Crystallography on Single-Crystal Regions of Inverse Bicontinuous Cubic Phases: Lipid Bilayer Structures and Gaussian Curvature Dependent Fluctuations. AB - I report for the first time an X-ray crystallographic study on single-crystal regions of cubic phases of a lyotropic liquid crystal. The single-crystal regions of three inverse bicontinuous cubic phases of a lipid, monoolein, diffracted X ray only in small-angle regions, but amplitudes of structure factors were determined from the small-angle X-ray diffraction data with high accuracy. Structure factors from lipid bilayer models with constant thickness were optimized to amplitudes obtained from the X-ray data. By using amplitudes of the structure factors from X-ray data and phases from the models, electron density maps of three cubic phases were reconstructed. Lipid bilayer membranes, consisting of high density head regions and low density tail regions, were clearly distinguished in the electron density maps. Water regions had slightly lower density than that of the lipid head regions and were clearly visible for two of the cubic phases. Centers of bilayer membranes were located on the corresponding triply periodic minimal surfaces in the maps. Electron density data indicated Gaussian curvature-dependent fluctuations of bilayer membranes: the smaller the Gaussian curvature is, the larger the fluctuation becomes. The technique described in this report is expected to bring new knowledge in the structural research of lyotropic liquid crystals.

AB - Modern transition state theory states that the statistical behavior of a chemical reaction is the sum of individual chemical events that occur randomly. Statistical analysis of each event for individual molecules in a three dimensional space however is practically impossible. We report here that kinetics and mechanisms of chemical reactions can be investigated by using a one dimensional system where reaction events can be observed in situ and counted one by one using variable-temperature (VT) atomic-resolution transmission electron microscopy (TEM). We thereby provide direct proof that the ensemble behavior of random events conforms to the Rice-Ramsperger-Kassel-Marcus theory, as illustrated for [2 + 2] cycloaddition of C60 molecules in carbon nanotubes (CNTs). This method gives kinetic and structural information for different types of reactions occurring simultaneously in the microscopic view field, suggesting that the VT-TEM opens a new dimension of chemical kinetics research on molecules and their assemblies in their excited and ionized states. The study carried out at 393-493 K showed that pristine CNT primarily acts as a singlet sensitizer of the cycloaddition reaction that takes place with an activation energy of 33.5 +/- 6.8 kJ/mol. On the other hand, CNT suffers electron damage of the conjugated system at 103-203 K and promotes a reactive radical cation path that takes place with an activation energy of only 1.9 +/- 0.7 kJ/mol. The pre-exponential factor of the Arrhenius plot gave us further mechanistic insights. PMID- 29172524 TI - Optimization of a Protease Activated Probe for Optical Surgical Navigation. AB - Molecularly targeted optical contrast agents have the potential to enable surgeons to visualize specific molecular markers that can help improve surgical precision and thus outcomes. Fluorescently quenched substrates can be used to highlight tumor lesions by targeting proteases that are highly abundant in the tumor microenvironment. However, the majority of these and other molecularly targeted optical contrast agents are labeled with reporter dyes that are not ideally matched to the properties of clinical camera systems, which are typically optimized for detection of indocyanine-green (ICG). While a wide range of near infrared (NIR) dyes are suitable for use with highly sensitive and highly tunable research-focused small animal imaging systems, most have not been evaluated for use with commonly used clinical imaging systems. Here we report the optimization of a small molecule fluorescently quenched protease substrate probe 6QC-ICG, which uses the indocyanine green (ICG) dye as its optical reporter. We evaluated dosing and kinetic parameters of this molecule in tumor-bearing mice and observed optimal tumor over background signals in as little as 90 min with a dose of 2.3 mg/kg. Importantly, the fluorescence intensity of the probe signal in tumors did not linearly scale with dose, suggesting the importance of detailed dosing studies. Furthermore, when imaged using the FDA approved da Vinci Si surgical system with Firefly detection, signals were significantly higher for the ICG probe compared to a corresponding probe containing a dye with similar quantum yield but with a slightly shifted excitation and emission profile. The increased signal intensity generated by the optimal dye and dose of the ICG labeled probe enabled detection of small, flat lesions that were less than 5 mm in diameter. Therefore, 6QC-ICG is a highly sensitive probe that performs optimally with clinical imaging systems and has great potential for applications in optical surgical navigation.

AB - Spectroscopically relevant properties in photosynthetic reaction centers change during charge separation. In this paper, we focus on incorporation of the complete set of environmental fluctuations in the modeling of the nonlinear spectra of molecular aggregates. The model is applied in simulations of two dimensional electronic spectra of a photosynthetic reaction center at low temperature (5 K), where spectral lines are narrow, such that more features can be resolved. We show that vertical cross sections of the simulated two dimensional spectra (with all populations in the lowest excited state) reveal transient hole-burned spectra excited resonantly within the B band in agreement with experiment, thus providing new insight into environmental fluctuation parameters of Rhodobacter sphaeroides at low temperatures. Correlated fluctuations of molecular parameters are found to be necessary to describe charge separated configurations of molecular excited states. PMID- 29172526 TI - Stronger Intermolecular Forces or Closer Molecular Spacing? Key Impact Factor Research of Gelator Self-Assembly Mechanism. AB - The benzene ring of low-molecular-weight gelators provides strong intermolecular forces but increases molecular spacing during self-assembly. To explore both of the above influences on the gel properties, we synthesize two gelators (Glu-CBZ and Glu-DPA) consisting of the same terminal long side chain but different aliphatic functional groups. The aliphatic functional groups are carbobenzoxy group and diphenyl phosphate group. The self-assembly driving forces, self organization patterns, network morphologies, rheological properties, and the influences of solvents are researched through 1H NMR spectra, Fourier transform infrared spectra, field-emission scanning electron microscopy images, rheological characterizations curves, tube-inversion experiment, and calculation of van't Hoff plots. The results show that the carbobenzoxy group of Glu-CBZ makes molecules pack more tightly such that it improves the gel properties during static equilibrium. Whereas the diphenyl phosphate group of Glu-DPA provides stronger intermolecular forces, performing outstandingly during dynamic equilibrium. It is advantageous to further investigate the competitive relationship in gel system between the increased number of functional groups and the consequent steric effect. PMID- 29172527 TI - Isotopically-Labeled Iodoacetamide-Alkyne Probes for Quantitative Cysteine Reactivity Profiling. AB - Cysteine residues on proteins serve a variety of catalytic and regulatory functions due to the high nucleophilicity and redox activity of the thiol group. Quantitative proteomic platforms for profiling cysteine reactivity can provide valuable information related to the post-translational modification state and inhibitor occupancy of functional cysteine residues within a complex proteome. Cysteine-reactivity profiling typically monitors changes in the extent of cysteine labeling by cysteine-reactive chemical probes, such as iodoacetamide (IA)-alkyne. To enable accurate measurements of cysteine reactivity changes, isotopic labels are introduced into the two proteomes of interest using either isotopically tagged proteomes (SILAC) or cleavable linkers (isoTOP-ABPP) that are installed using copper-catalyzed azide-alkyne cycloaddition (CuAAC). Here we provide an alternative strategy for isotopic tagging of two proteomes for cysteine-reactivity profiling by developing IA-light and IA-heavy, a pair of isotopically labeled iodoacetamide-alkyne probes. These probes can be utilized for proteome samples that are not amenable to SILAC labeling and are facile to synthesize, especially when compared to the isotopically tagged cleavable linkers. We confirm the quantitative accuracy of IA-light and IA-heavy by assessing cysteine reactivity in a purified thioredoxin protein, as well as globally within a complex proteome where IA-light treatment generates mass spectrometry identification of 992 cysteine residues. Importantly, these isotopically tagged probes can also be utilized for quantifying the percentage of cysteine modification within a single sample. Preliminary data supports the use of these tags to quantify the stoichiometry of TCEP-susceptible cysteine oxidation events in cell lysates.

AB - This contribution reports the synthesis and evaluation of novel hybrid compounds that conjugate a sigma (sigma) receptor pharmacophore and a nitric oxide (NO) photodonor. All compounds preserve their capability to generate NO under visible light and possess overall sigma receptor nanomolar affinity, with one of them (8b) exhibiting remarkable sigma2 receptor selectivity. Compounds 8b, 11a, and 11b were tested on tumorigenic MCF-7 and A2058 cells expressing high levels of sigma2 and sigma1 receptor, respectively. Considerable loss of cell viability was detected under light excitation, while negligible effects in the dark were detected. Moreover, they did not show any significant cytotoxicity in the dark or under irradiation on nontumorigenic NCTC-2544 keratinocytes. NO-induced reduction of cellular viability was demonstrated by in-cell NO detection and total nitrite estimation. For the first time, a combination of sigma receptor moieties and a NO photodonor is reported, providing distinctive ligands potentially useful for cancer management.

AB - Until now, it has been a challenge to prepare lanthanide metal-organic framework films on traditional substrates, like zinc plate, indium oxide (ITO), and fluorine-doped tin oxide (FTO) glasses in a rapid and facile method. In this paper, continuous and dense Ln-BTC MOFs films on unmodified low-cost substrates have been rapidly and easily fabricated though the newly developed electrophoretic deposition (EPD) method in 5 min. Moreover, the as-prepared luminescent films were successfully used for the detection of nitrobenzene (NB), trinitrotoluene (TNT) in gas phases, as well as NB, Cr3+ ions for detection in solution. PMID- 29172530 TI - Effect of Ethanethiolate Spacer on Morphology and Optical Responses of Ag Nanoparticle Array-Single Layer Graphene Hybrid Systems. AB - Single layer graphene (SLG) and two-dimensional (2-D) plasmonic Ag nanoparticle arrays assembled by chemisorption of ethanethiol (ET) molecules (AgNPs-ET) were employed as components of two types of hybrid systems designed for surface enhanced Raman scattering (SERS) spectral probing of SLG localized in the vicinity of plasmonic NPs. Both hybrids were characterized by optical microscopy, transmission electron microscopy (TEM), surface plasmon extinction (SPE), and SERS microRaman spectral measurements at four excitation wavelengths spanning the 445-780 nm range. SERS spectral probing of the glass/SLG/AgNPs-ET hybrid prepared by overdeposition of SLG on glass by the array of ET-modified Ag NPs has shown that the chemisorbed ET acts as an efficient molecular spacer between SLG and Ag NPs surface which, in turn, enabled to obtain SERS spectra of SLG unperturbed by doping or strain. TEM imaging and SERS spectral probing of the second hybrid prepared by overdeposition of AgNPs-ET array on glass by SLG revealed removal of the adsorbed ET molecules and annealing of Ag NPs during the SLG deposition. The characteristics of the resulting glass/AgNPs/SLG hybrid system, namely (i) broad distribution of the annealed Ag NPs sizes and shapes, (ii) SPE curve covering the overall visible spectral region, (iii) absence of the ET spectral bands in SERS spectra, and (iv) fairly uniform SERS enhancement of the G and 2D mode of SLG in the 532-780 nm range in the straight sample geometry indicate that this hybrid can provide a suitable platform for investigation of the excitation wavelength dependence of combined SERS/GERS (graphene-enhanced Raman scattering) enhancement experienced by various molecular species brought into contact with SLG in this hybrid. Finally, weak optical effects attributed to increased reflectivity of SLG in the near field of Ag NPs arrays have been observed in the excitation wavelength dependence of the SERS spectra of both types of hybrid systems.

AB - The visible light-mediated C-3 alkoxylation of imidazopyridines with alcohols has been achieved using rose bengal as an organic photoredox catalyst at room temperature. Widely abundant air acts as the terminal oxidant that avoids the use of a stoichiometric amount of peroxo compounds.

PMID- 29172532 TI - Enhancing Mucosal Immune Response of Newcastle Disease Virus DNA Vaccine Using N 2-Hydroxypropyl Trimethylammonium Chloride Chitosan and N,O-Carboxymethyl Chitosan Nanoparticles as Delivery Carrier. AB - Because mucosal sites are the entry ports of pathogens, immunization via mucosal routes can extremely enhance the immunity. To elevate the potential of N-2 hydroxypropyl trimethylammonium chloride chitosan (N-2-HACC) and N,O carboxymethyl chitosan (CMC) nanoparticles as a mucosal immune delivery carrier for DNA vaccines, we prepared the NDV F gene plasmid DNA with C3d6 molecular adjuvant (pVAX I-F(o)-C3d6) encapsulated in the N-2-HACC-CMC nanoparticles (N-2 HACC-CMC/pFDNA-C3d6 NPs). The N-2-HACC-CMC/pFDNA-C3d6 NPs had regular spherical morphology and low toxicity with a mean diameter of 309.7 +/- 6.52 nm, zeta potential of 49.9 +/- 4.93 mV, encapsulation efficiency of 92.27 +/- 1.48%, and loading capacity of 50.75 +/- 1.35%. The N-2-HACC-CMC had high stability and safety. The pVAX I-F(o)-C3d6 could be sustainably released from the N-2-HACC CMC/pFDNA-C3d6 NPs after an initial burst release. Immunization intranasally of chickens with N-2-HACC-CMC/pFDNA-C3d6 NPs not only produced higher anti-NDV IgG and sIgA antibody than chickens in other groups did, but also significantly stimulated lymphocyte proliferation and triggered higher the IL-2, IL-4, and IFN gamma levels. These findings indicated that the N-2-HACC-CMC could be used as an efficient delivery carrier for the mucosal immunity of Newcastle disease virus DNA vaccine. The work laid a basis for the quaternized chitosan nanoparticles as efficient mucosal immunity delivery carrier for DNA vaccines and had immense application promise and potential for vaccines and drugs.

AB - The head-to-head impact of diesel-fuel droplets on a polished spherical brass target has been investigated experimentally. High-speed imaging was employed to visualize the impact process for wall surface temperatures and Weber and Reynolds numbers in the ranges of 140-340 degrees C, 30-850, and 210-1135, respectively. The thermohydrodynamic outcome regimes occurring for the aforementioned ranges of parameters were mapped on a We-T diagram. Seven clearly distinguishable postimpact outcome regimes were identified, which are conventionally called the coating, splash, rebound, breakup-rebound, splash-breakup-coating, breakup coating, and splash-breakup-rebound regimes. In addition, the effects of the Weber number and surface temperature on the wettability dynamics were examined; the temporal variations of the dynamic contact angle, dimensionless spreading diameter, and liquid film thickness forming on the solid particle were measured and are reported. PMID- 29172534 TI - Early Dynamics and Stabilization Mechanisms of Oil-in-Water Emulsions Containing Colloidal Particles Modified with Short Amphiphiles: A Numerical Study. AB - Emulsions stabilized by mixtures of particles and amphiphilic molecules are relevant for a wide range of applications, but their dynamics and stabilization mechanisms on the colloidal level are poorly understood. Given the challenges to experimentally probe the early dynamics and mechanisms of droplet stabilization, Brownian dynamics simulations are developed here to study the behavior of oil-in water emulsions stabilized by colloidal particles modified with short amphiphiles. Simulation parameters are based on an experimental system that consists of emulsions obtained with octane as the oil phase and a suspension of alumina colloidal particles modified with short carboxylic acids as the continuous aqueous medium. The numerical results show that attractive forces between the colloidal particles favor the formation of closely packed clusters on the droplet surface or of a percolating network of particles throughout the continuous phase, depending on the amphiphile concentration. Simulations also reveal the importance of a strong adsorption of particles at the liquid interface to prevent their depletion from the droplet surface when another droplet approaches. Strongly adsorbed particles remain immobile on the droplet surface, generating an effective steric barrier against droplet coalescence. These findings provide new insights into the early dynamics and mechanisms of stabilization of emulsions using particles and amphiphilic molecules. PMID- 29172535 TI - Dewetting-Induced Photoluminescent Enhancement of Poly(lauryl methacrylate)/Quantum Dot Thin Films. AB - A new method for enhancing photoluminescence from quantum dot (QD)/polymer nanocomposite films is proposed. Poly(lauryl methacrylate) (PLMA) thin films containing embedded QDs are intentionally allowed to undergo dewetting on substrates by exposure to a nonsolvent vapor. After controlled dewetting, films exhibited typical dewetting morphologies with increased amounts of scattering that served to outcouple photoluminescence from the film and reduce internal light propagation within the film. Up to a 5-fold enhancement of the film emission was achieved depending on material factors such as the initial film thickness and QD concentration within the film. An increase in initial film thickness was shown to increase the dewetted maximum feature size and its characteristic length until a critical thickness was reached where dewetting became inhibited. A unique light exposure-based photopatterning method is also presented for the creation of high contrast emissive patterns as guided by spatially controlled dewetting. PMID- 29172536 TI - Role of Torsion-Vibration Coupling in the Overtone Spectrum and Vibrationally Mediated Photochemistry of CH3OOH and HOOH. AB - The yield of vibrationally excited OH fragments resulting from the vibrationally mediated photodissociation of methyl hydroperoxide (CH3OOH) excited in the vicinity of its 2nuOH and 3nuOH stretching overtones is compared with that resulting from excitation of the molecule to states with three quanta in the CH stretches and to the state with two quanta in the OH stretch and one in the OOH bend (2nuOH + nuOOH). We find that the OH fragment vibrational state distribution depends strongly on the vibrational state of CH3OOH prior to photodissociation. Specifically, dissociation from the CH stretch overtones and the stretch/bend combination band involving the OH stretch and OOH bend produced significantly less vibrationally excited OH fragments compared to that produced following excitation of CH3OOH to an overtone in the OH stretch. While the absence of vibrationally excited OH photoproducts following excitation of the CH overtone is not surprising, the lack of vibrationally excited OH following excitation to the 2nuOH+nuOOH combination band is unexpected given that photodissociation following excitation to the lower-energy 2nuOH state produces OH products in v = 1 as well as in its ground state. This trend persists even when the electronic photodissociation wavelength is changed from 532 to 355 nm and thus suggests that the observed disparity arises from differences in the nature of the initially populated vibrational states. This lack of vibrationally excited OH products likely reflects the enhanced intramolecular vibrational energy redistribution associated with the stretch/bend combination level compared to the pure OH stretch overtone. Consistent with this hypothesis, photodissociation from the stretch/bend combination level of the smaller HOOH molecule produces more vibrationally excited OH fragments compared to that resulting from the corresponding state of CH3OOH. These results are investigated using second-order vibrational perturbation theory based on an internal coordinate representation of the normal modes. Consistent with the observations, the first-order correction to the wave function shows stronger coupling of the 2nuOH+nuOOH state to states with torsion excitation compared to the other bands considered in this study.

AB - Ultrastrong light-matter coupling allows the exploration of new states of matter through the interaction of strong vacuum fields with huge electronic dipoles. By using hybrid dipole antenna-split ring resonator-based cavities with extremely small effective mode volumes Veff/lambda03 ? 6 * 10-10 and surfaces Seff/lambda02 ? 3.5 * 10-7, we probe the ultrastrong light-matter coupling at 300 GHz to less than 100 electrons located in the last occupied Landau level of a high mobility two-dimensional electron gas, measuring a normalized coupling ratio of OmegaR/omegac = 0.36. Effects of the extremely reduced cavity dimensions are observed as the light-matter coupled system is better described by an effective mass heavier than the uncoupled one. These results open the way to ultrastrong coupling at the single-electron level in two-dimensional electron systems. PMID- 29172538 TI - Real-Time Atomic Force Microscopy Imaging of Block Copolymer Directed Self Assembly. AB - The kinetics of directed self-assembly of symmetric PS-b-PMMA diblock copolymer on chemically patterned templates were measured during in situ thermal annealing. Although these chemical guide patterns lead to well-aligned, defect-free lamellar patterns at thermodynamic equilibrium, in practice, challenges remain in understanding and optimizing the kinetic evolution for technological applications. High-speed, environmentally controlled atomic force microscopy imaging was used to track pattern evolution on the time scale of individual microdomain connections in real space and time, allowing the direct visualization of defect healing mechanisms. When we apply this highly general technique to films on chemically patterned substrates, we find that pattern alignment is mediated by a metastable nonbulk morphology unique to these samples, referred to as the "stitch" morphology. We observe diverse and anisotropic mechanisms for the conversion from this morphology to equilibrium lamellar stripes. Directed self assembly on chemical templates is observed to follow exponential kinetics with an apparent energetic barrier of 360 +/- 80 kJ/mol from 210-230 degrees C, a significant enhancement when compared with ordering rates on unpatterned substrates. Ultimately, from local imaging, we find that the presence of a chemical guiding field causes morphological ordering and lamellar alignment to occur irreversibly. PMID- 29172539 TI - Proteome Comparisons between Hemolymph of Two Honeybee Strains (Apis mellifera ligustica) Reveal Divergent Molecular Basis in Driving Hemolymph Function and High Royal Jelly Secretion. AB - Hemolymph is vital for the immunity of honeybees and offers a way to investigate their physiological status. To gain novel insight into the functionality and molecular details of the hemolymph in driving increased Royal Jelly (RJ) production, we characterized and compared hemolymph proteomes across the larval and adult ages of Italian bees (ITbs) and Royal Jelly bees (RJbs), a stock selected from ITbs for increasing RJ output. Unprecedented in-depth proteome was attained with the identification of 3394 hemolymph proteins in both bee lines. The changes in proteome support the general function of hemolymph to drive development and immunity across different ages. However, age-specific proteome settings have adapted to prime the distinct physiology for larvae and adult bees. In larvae, the proteome is thought to drive temporal immunity, rapid organogenesis, and reorganization of larval structures. In adults, the proteome plays key roles in prompting tissue development and immune defense in newly emerged bees, in gland maturity in nurse bees, and in carbohydrate energy production in forager bees. Between larval and adult samples of the same age, RJbs and ITbs have tailored distinct hemolymph proteome programs to drive their physiology. In particular, in day 4 larvae and nurse bees, a large number of highly abundant proteins are enriched in protein synthesis and energy metabolism in RJbs. This implies that they have adapted their proteome to initiate different developmental trajectories and high RJ secretion in response to selection for enhanced RJ production. Our hitherto unexplored in-depth proteome coverage provides novel insight into molecular details that drive hemolymph function and high RJ production by RJbs. PMID- 29172540 TI - Discovery of a Small-Molecule Bromodomain-Containing Protein 4 (BRD4) Inhibitor That Induces AMP-Activated Protein Kinase-Modulated Autophagy-Associated Cell Death in Breast Cancer. AB - Upon the basis of The Cancer Genome Atlas (TCGA) data set, we identified that several autophagy-related proteins such as AMP-activated protein kinase (AMPK) were remarkably downregulated in breast cancer. Combined with coimmunoprecipitation assay, we demonstrated that BRD4 might interact with AMPK. After analyses of the pharmacophore and WPF interaction optimization, we designed a small-molecule inhibitor of BRD4, 9f (FL-411) which was validated by cocrystal structure with BD1 of BRD4. Subsequently, 9f was discovered to induce ATG5 dependent autophagy-associated cell death (ACD) by blocking BRD4-AMPK interaction and thus activating AMPK-mTOR-ULK1-modulated autophagic pathway in breast cancer cells. Interestingly, the iTRAQ-based proteomics analyses revealed that 9f induced ACD pathways involved in HMGB1, VDAC1/2, and eEF2. Moreover, 9f displayed a therapeutic potential on both breast cancer xenograft mouse and zebrafish models. Together, these results demonstrate that a novel small-molecule inhibitor of BRD4 induces BRD4-AMPK-modulated ACD in breast cancer, which may provide a candidate drug for future cancer therapy. PMID- 29172541 TI - Parallel-Coupled Quantum Dots in InAs Nanowires. AB - We use crystal-phase tuning during epitaxial growth of InAs nanowires to create quantum dots with very strong confinement. A set of gate electrodes are used to reproducibly split the quantum dots into even smaller pairs for which we can control the populations down to the last electron. The double quantum dots, which are parallel-coupled to source and drain, show clear and stable odd-even level pairing due to spin degeneracy and the strong confinement. The combination of hard-wall barriers to source and drain, shallow interdot tunnel barriers, and very high single-particle excitation energies allow an order of magnitude tuning of the strength for the first intramolecular bond. We show examples for nanowires with different facet orientations, and suggest possible mechanisms behind the reproducible double-dot formation. PMID- 29172542 TI - Enzyme and Chemical Assisted N-Terminal Blocked Peptides Analysis, ENCHANT, as a Selective Proteomics Approach Complementary to Conventional Shotgun Approach. AB - Shotgun (bottom-up) approach has been widely applied in large-scale proteomics studies. The inherent shortages of shotgun approach lie in that the generated peptides often overwhelm the analytical capacity of current LC-MS/MS systems and that high-abundance proteins often hamper the identification of low-abundance proteins when analyzing complex samples. To reduce the sample complexity and relieve the problems caused by abundant proteins, herein we introduce a modified selective proteomics approach, termed ENCHANT, for enzyme and chemical assisted N terminal blocked peptides analysis. Modified from our previous Nalpha-acetylome approach, ENCHANT aims to analyze three kinds of peptides, acetylated protein N termini, N-terminal glutamine and N-terminal cysteine containing peptides. Application of ENCHANT to HeLa cells allowed to identify 3375 proteins, 19.6% more than that by conventional shotgun approach. More importantly, ENCHANT demonstrated an excellent complementarity to conventional shotgun approach with the overlap of 34.5%. In terms of quantification using data independent acquisition (DIA) technology, ENCHANT quantified 23.9% more proteins than conventional shotgun approach with the overlap of 27.6%. Therefore, our results strongly suggest that ENCHANT is a promising selective proteomics approach, which is complementary to conventional shotgun approach in both qualitative and quantitative proteomics studies. Data are available via ProteomeXchange with identifier PXD007863. PMID- 29172543 TI - Large Proximity-Induced Spin Lifetime Anisotropy in Transition-Metal Dichalcogenide/Graphene Heterostructures. AB - Van der Waals heterostructures have become a paradigm for designing new materials and devices in which specific functionalities can be tailored by combining the properties of the individual 2D layers. A single layer of transition-metal dichalcogenide (TMD) is an excellent complement to graphene (Gr) because the high quality of charge and spin transport in Gr is enriched with the large spin-orbit coupling of the TMD via the proximity effect. The controllable spin-valley coupling makes these heterostructures particularly attractive for spintronic and opto-valleytronic applications. In this work, we study spin precession in a monolayer MoSe2/Gr heterostructure and observe an unconventional, dramatic modulation of the spin signal, showing 1 order of magnitude longer lifetime of out-of-plane spins compared to that of in-plane spins (tau? ~ 40 ps and tau? ~ 3.5 ps). This demonstration of a large spin lifetime anisotropy in TMD/Gr heterostructures, is a direct evidence of induced spin-valley coupling in Gr and provides an accessible route for manipulation of spin dynamics in Gr, interfaced with TMDs. PMID- 29172544 TI - A Substrate-Selective Enzyme-Catalysis Assembly Strategy for Oligopeptide Hydrogel-Assisted Combinatorial Protein Delivery. AB - Oligopeptide hydrogels for localized protein delivery have considerable potential to reduce systemic side effects but maximize therapeutic efficacy. Although enzyme catalysis to induce formation of oligopeptide hydrogels has the merits of unique regio- and enantioselectivity and mild reaction conditions, it may cause the impairment of function and activity of the encapsulated proteins by proteolytic degradation during gelation. Here we report a novel enzyme-catalysis strategy for self-assembly of oligopeptide hydrogels using an engineered protease nanocapsule with tunable substrate selectivity. The protease-encapsulated nanocapsule shielded the degradation activity of protease on the laden proteins due to the steric hindrance by the polymeric shell weaved around the protease, whereas the small-molecular precursors were easier to penetrate across the polymeric network and access the catalytic pocket of the protease to convert to the gelators for self-assembling hydrogel. The resulting oligopeptide hydrogels supported a favorable loading capacity without inactivation of both an antiangiogenic protein, hirudin and an apoptosis-inducing cytokine, TRAIL as model proteins. The hirudin and TRAIL coloaded oligopeptide hydrogel for combination cancer treatment showed enhanced synergistic antitumor effects both in vitro and in vivo. PMID- 29172545 TI - Sulfur Adatom and Vacancy Accelerate Charge Recombination in MoS2 but by Different Mechanisms: Time-Domain Ab Initio Analysis. AB - Two-dimensional transition metal dichalcogenides (TMDs) have appeared on the horizon of materials science and solid-state physics due to their unique properties and diverse applications. TMD performance depends strongly on material quality and defect morphology. Calculations predict that sulfur adatom and vacancy are among the most energetically favorable defects in MoS2 with vacancies frequently observed during chemical vapor deposition. By performing ab initio quantum dynamics calculations we demonstrate that both adatom and vacancy accelerate nonradiative charge carrier recombination but this happens through different mechanisms. Surprisingly, holes never significantly populate the shallow trap state created by the sulfur adatom because the trap is strongly localized and decoupled from free charges. Charge recombination bypasses the hole trap. Instead, it occurs directly between free electron and hole. The recombination is faster than in pristine MoS2 because the adatom strongly perturbs the MoS2 layer, breaks its symmetry, and allows more phonon modes to couple to the electronic subsystem. In contrast, the sulfur vacancy accelerates charge recombination by the traditional mechanism involving charge trapping, followed by recombination. This is because the hole and electron traps created by the vacancy are much less localized than the hole trap created by the adatom. Because the sulfur adatom accelerates charge recombination by a factor of 7.9, compared to 1.7 due to vacancy, sulfur adatoms should be strongly avoided. The generated insights highlight the diverse behavior of different types of defects, reveal unexpected features, and provide the mechanistic understanding of charge dynamics needed for tailoring TMD properties and building high-performance devices.

The resulting alkylboron products that contain a N-heteroaryl moiety are afforded in up to 97% yield and 99:1 enantiomeric ratio. The highly versatile C-B(pin) bond can be converted to a range of useful functional groups, delivering a variety of enantiomerically enriched building blocks that are otherwise difficult to access. The utility of this method is further demonstrated by application to a fragment synthesis of biologically active molecule U-75302.

AB - As wearable fitness devices have gained commercial acceptance, interest in real time monitoring of an individual's physiological status using noninvasive techniques has grown. Microneedles have been proposed as a minimally invasive technique for sampling the dermal interstitial fluid (ISF) for clinical monitoring and diagnosis, but little is known about its composition. In this study, a novel microneedle array was used to collect dermal ISF from three healthy human donors and compared with matching serum and plasma samples. Using a shotgun quantitative proteomic approach, 407 proteins were quantified with at least one unique peptide, and of those, 135 proteins were differently expressed at least 2-fold. Collectively, these proteins tended to originate from the cytoplasm, membrane bound vesicles, and extracellular vesicular exosomes. Proteomic analysis confirmed previously published work that indicates that ISF is highly similar to both plasma and serum. In this study, less than one percent of proteins were uniquely identified in ISF. Taken together, ISF could serve as a minimally invasive alternative for blood-derived fluids with potential for real time monitoring applications.

AB - We report the formation of blue emitting Zn(MSA)2 complex on the surface of a yellow emitting ZnO quantum dot (Qdot)-out of a complexation reaction between N methylsalicylaldimine (MSA) and ZnO Qdot. This led to formation of a highly luminescent, photostable, single-component nanocomposite that emits bright natural white light, with (i) chromaticities of (0.31, 0.38) and (0.31, 0.36), (ii) color rendering indices (CRI) of 74 and 82, and (iii) correlated color temperatures (CCT) of 6505 and 6517 K in their solution and solid phases, respectively. Importantly, the control over the chromaticity and CCT-depending upon the degree of complexation-makes the reported nanocomposite a potential new advanced material in fabricating cost-effective single-component white light emitting devices (WLED) of choice and design in the near future. PMID- 29172551 TI - Synthesis of Excitation Independent Highly Luminescent Graphene Quantum Dots through Perchloric Acid Oxidation. AB - We demonstrate a facile liquid phase exfoliation method by only using perchloric acid to synthesize graphene quantum dots (GQDs) having excitation independent strong emission with a quantum yield of about 14%. The proposed simplified synthesis strategy can help in overcoming the limitations of existing aqueous routes which produce GQDs with excitation dependent emission and of low quantum efficiency. Photoluminescence (PL) properties of GQDs have been studied in detail to understand the origin of emission. As-synthesized GQDs show excitation independent photoluminesce (PL) which suggests that the synthesized materials do not have any significant defects. Spectral analysis suggests that the PL emission of the well-defined GQDs originates mainly from the peripheral functional groups conjugated with carbon backbone planes. We also demonstrate a relatively longer PL lifetime (average lifetime of about 10 ns) of the synthesized GQDs determined by time correlated single photon counting (TCSPC) measurement and this high lifetime suggests that the synthesized GQDs may be suitable for biomacromolecular probing. In addition, as-synthesized GQDs interestingly show delayed fluorescence and steady state anisotropy, which make the material an appropriate candidate for application in sensing and bioimaging of cells and organisms.

AB - Treatment of ortho-amino-substituted aryldiyne derivatives with sulfonyl hydrazides in the presence of tetrabutylammonium iodide (TBAI) and tert-butyl hydroperoxide (TBHP) led to a cascade cyclization reaction to yield sulfonylated indeno[1,2-c]quinolines in moderate to good yields. The features of the methodology include metal-free reaction, the ease of reagent handling, and a broad functional group tolerance. PMID- 29172553 TI - General Method for the Suzuki-Miyaura Cross-Coupling of Primary Amide-Derived Electrophiles Enabled by [Pd(NHC)(cin)Cl] at Room Temperature. AB - A general, highly selective method for the room temperature Suzuki-Miyaura cross coupling of commonly encountered primary benzamides is reported. A combination of site-selective N,N-di-Boc-activation (tert-butoxycarbonyl activation) of the amide nitrogen with practical air- and moisture-stable, well-defined, and highly reactive [Pd(NHC)(cin)Cl] (NHC = N-heterocyclic carbene; cin = cinnamyl) provides a highly effective route to biaryl ketones from primary amides in high yields. For the first time, a TON of >1000 has been achieved in amide acyl cross coupling. PMID- 29172554 TI - Interfacing five-factor model and triarchic conceptualizations of psychopathy. AB - The lexically based five-factor model (FFM) of personality has been a highly influential research framework for characterizing clinical-psychological conditions, including psychopathy, in lexical-trait terms. An alternative trait descriptive framework, the triarchic model was formulated to characterize psychopathy in neurobehavioral-trait terms, in order to facilitate linkages with variables in the domain of neurobiology. The current study used data from a mixed gender sample (N = 769; M age = 19.3) to establish an interface between the FFM and triarchic frameworks by identifying subsets of items from a widely used five factor personality inventory, the NEO Personality Inventory-Revised (NEO-PI-R), that effectively index the dimensional constructs of the triarchic model (boldness, meanness, and disinhibition). A consensus rating and psychometric refinement approach was used to select NEO-PI-R items for assessing each triarchic dimension, and the resulting NEO-Tri item-sets ("scales") were evaluated in relation to criteria including other scale measures of the triarchic constructs, reported antisocial behavior and drug/alcohol use, and an FFM generated omnibus psychopathy measure, the Psychopathy Resemblance Index. The NEO Tri scales were also evaluated for effectiveness as indicators of latent triarchic dimensions within a confirmatory factor analysis anchored by previously validated triarchic scale measures. Results of this work have implications for clarifying how the triarchic model dimensions relate to normal-range personality traits and FFM-based conceptions of psychopathy, and provide a foundation for further examining neurobiological correlates of the triarchic model dimensions using existing multidomain data-sets that include the NEO-PI-R. (PsycINFO Database Record PMID- 29172555 TI - Visiting Auschwitz: Evidence of secondary traumatization among high school students. AB - Secondary traumatic stress has been intensively studied among survivors' therapists, family members, and trauma researchers. We claim that people who are exposed to reminders of past traumatic experiences when visiting places of memory or museum exhibitions could also develop secondary trauma symptoms. Thus, scholars and practitioners must better understand how such places related to historical traumatization (e.g., Holocaust memorial sites) can affect the psychological well-being of visitors. The main aim of this quantitative longitudinal study was to assess the scale of secondary traumatization among visitors to such places. The study found that the syndrome of secondary traumatic stress was observed among 13.2% of high school visitors to the Auschwitz memorial museum. Longitudinal analysis revealed that empathic reactions to the visit in Auschwitz (e.g., a greater inclusion of victims into the self) were associated with higher levels of secondary traumatic stress levels 1 month after the visit. This study suggests that visits to places related to traumatic past events should be preceded by a more intense elaboration of Holocaust history and by proper psychological preparations. (PsycINFO Database Record PMID- 29172556 TI - Bullying and minorities in secondary school students in Thrace-Greece. AB - The aim of the present study is to examine probable heterogeneity in aggressive behaviors and peer victimization among ethnically diverse secondary schools in Thrace. It is a culturally diverse region in Northeastern Greece, which includes Greek Christians and a significant minority of Muslims and immigrants. The study population consisted of 572 school students (293 girls, 279 boys, Mage = 14.24), who completed the Revised Olweus Bully/Victim Questionnaire for Students-Senior and the Youth Self-Report. The percentage of students involved in bullying was 34.7%. More specifically, we found that 24.7% of the students were bully victims, followed by 18.5% bully/victims, and 17.8% bullies. Peer victimization was 52% less frequent in schools with low proportion of minority students (low school minority density; adjusted odds ratio [AOR] = 0.48, p = .015) and 61% less frequent in schools with high minority density (AOR = 0.39, p = .010) as compared to schools with moderate minority density. Furthermore, bullying and bully/victims behaviors were at least 65% less frequent in schools with high density (bullying: AOR = 0.35, p = .016; bully/victim: AOR = 0.30, p = .027) as compared to schools with moderate density, while a similar tendency was also observed in low density areas. Findings from the current study have implications for research and practice. More specifically, our findings can contribute to the development of effective prevention policies and strategies. (PsycINFO Database Record PMID- 29172557 TI - Expanding the early and late starter model of criminal justice involvement for forensic mental health clients. AB - The early and late starter model provides one of the most enduring frameworks for understanding the developmental course and severity of violence and criminality among individuals with severe mental illness. We expanded the model to account for differences in the age of onset of criminal behavior and added a group with no prior contact with the justice or mental health systems. We sampled 1,800 men and women found Not Criminally Responsible on account of Mental Disorder in 3 Canadian provinces. Using a retrospective file-based study, we explored differences in criminal, health, demographic, and social functioning characteristics, processing through the forensic psychiatric system and recidivism outcomes of 5 groups. We replicated prior research, finding more typical criminogenic needs among those with early onset crime. Those with crime onset after mental illness were more likely to show fewer criminogenic needs and to have better outcomes upon release than those who had crime onset during adulthood, before mental illness. Individuals with no prior contact with mental health or criminal justice had higher functioning prior to their crime and had a lower risk of reoffending. Given little information is needed to identify the groups, computing the distribution of these groups within forensic mental health services or across services can provide estimates of potential intensity or duration of services that might be needed. This study suggests that distinguishing subgroups of forensic clients based on the sequence of onset of mental illness and criminal behavior and on the age of onset of criminal behavior may be useful to identify criminogenic needs and predict outcomes upon release. This updated framework can be useful for planning organization of services, understanding case mix, as well as patient flow in forensic services and flow of mentally disordered offenders in correctional services. (PsycINFO Database Record PMID- 29172558 TI - Childhood risk factors associated with adolescent gun carrying among Black and White males: An examination of self-protection, social influence, and antisocial propensity explanations. AB - Adolescent gun violence is a serious public health issue that disproportionately affects young Black males. Although it has been postulated that differential exposure to childhood risk factors might account for racial differences in adolescent gun carrying, no longitudinal studies have directly examined this issue. We examined whether childhood risk factors indexing neighborhood crime, peer delinquency, and conduct problems predicted the initiation of adolescent gun carrying among a community sample of Black and White boys. Analyses then examined whether racial differences in risk factors accounted for racial differences in gun carrying. Data came from a sample of 485 Black and White boys who were repeatedly assessed from 2nd grade until age 18. Multi-informant data collected across the first 3 years of the study were used to assess neighborhood crime, peer delinquency, and conduct problems. Illegal gun carrying was assessed annually from 5th grade through age 18. Growth curve analyses indicated that children with higher initial levels of conduct problems and delinquent peer involvement, as well as those who increased in conduct problems across childhood, were more likely to carry a gun prior to age 18. Black boys were also more likely to carry guns than Whites. Racial differences were greatly reduced, but not eliminated, after controlling for initial levels of conduct problems and delinquent peer involvement. Findings suggest that early prevention programs designed to reduce adolescent gun violence (including racial disparities in gun violence) should target boys with severe conduct problems and those who affiliate with delinquent peers during elementary school. (PsycINFO Database Record PMID- 29172559 TI - Quantification of virtue in late Medieval Europe. AB - Fourteenth century Europe saw a growing interest in quantification. This interest has been well studied by historians of physical sciences, but medieval scholars were also interested in the quantification of psychological qualities. In general, the quantification issues addressed by medieval scholars were theoretical, even (by our standards) mathematical, rather than those of practical measurement. There was recognition that the seriousness of a sin and the penance laid down for it should be proportionate. A number of late medieval scholars were interested in the quantification of caritas, a Latin word that is translatable as charity or loving benevolence. The scholastic interest linked to the practical issue of how caritas might become habitual through the repeated performance of virtuous acts. Gregory of Rimini's treatment of caritas in his commentary on Peter Lombard's Sentences illustrates how one medieval scholar related the quantification of virtue to the quantification of physical qualities such as temperature and luminescence. (PsycINFO Database Record PMID- 29172560 TI - The testing effect in a social setting: Does retrieval practice benefit a listener? AB - Retrieval practice boosts retention relative to other study strategies like restudying, a finding known as the testing effect. In 3 experiments, the authors investigated testing in social contexts. Subjects participated in pairs and engaged in restudy and retrieval practice of vocabulary pairs. During retrieval practice, 1 subject acted as speaker (overt practice); the other subject listened and monitored the speaker's responses (covert practice). All experiments showed testing effects, with overt practice by speakers enhancing recall relative to restudy after a 2-day delay. In Experiments 1 and 2, covert practice by listeners did not benefit recall as much as overt practice. Only in Experiment 3, when listeners were asked to monitor their own covert retrieval (instead of the speaker's overt retrieval), did both types of practice convey similar benefits. The results indicate that memory retrieval is not necessarily as beneficial for listeners as for speakers. The practical implication is that the practice of teachers asking questions in class will not yield a positive effect unless special measures are taken to insure students' effortful covert retrieval. (PsycINFO Database Record PMID- 29172561 TI - Service usage typologies in a clinical sample of trauma-exposed adolescents: A latent class analysis. AB - OBJECTIVE: The purpose of this study is to describe typologies of service utilization among trauma-exposed, treatment-seeking adolescents and to examine associations between trauma history, trauma-related symptoms, demographics, and service utilization. METHOD: Latent class analysis was used to derive a service utilization typologies based on 10 service variables using a sample of 3,081 trauma-exposed adolescents ages 12 to 16 from the National Child Traumatic Stress Network Core Dataset. Services used 30 days prior to the initial assessment from 5 sectors were examined (health care, mental health, school, social services, and juvenile justice). RESULTS: A 5-class model was selected based on statistical fit indices and substantive evaluation of classes: (a) High intensity/multisystem, 9.5%; (b) Justice-involved, 7.2%; (c) Low intensity/multisystem, 19.9%; (d) Social service and mental health, 19.9%; and (e) Low service usage/reference, 43.5%. The classes could be differentiated based on cumulative trauma, maltreatment history, PTSD, externalizing and internalizing symptoms, and age, gender, race/ethnicity and place of residence. CONCLUSIONS: This study provides new evidence about patterns of service utilization by trauma exposed, treatment seeking adolescents. Most of these adolescents appear to be involved with at least 2 service systems prior to seeking trauma treatment. Higher cumulative exposure to multiple types of trauma was associated with greater service utilization intensity and complexity, but trauma symptomatology was not.

PMID- 29172562 TI - Association between perceptions of military service and mental health problems in a nationally representative sample of United States military veterans. AB - OBJECTIVE: In this study, we examined the prevalence of positive and negative perceptions of military service, associations between these perceptions and other demographic and military-related factors, and the extent to which endorsement of positive and negative perceptions of military service are associated with current mental health problems among United States veterans. METHOD: We analyzed data from the National Health and Resilience in Veterans Study (NHRVS), a nationally representative survey of 1,484 United States military veterans, 564 of which reported combat exposure. We assessed perceptions of the effects of military service using a scale developed by Elder and Clipp (1989). RESULTS: Results showed that desirable effects of service (53.6-86.5%) were more frequently endorsed than undesirable effects (9.5%-48.1%), and that combat-exposed veterans (11.5%-59.7%) were more likely to endorse undesirable effects of service than veterans without combat exposure (4.0%-40.7%). We also found that undesirable effects of service predicted significantly higher odds of probable current mental health disorders (OR = 1.08, 95% CI [1.04, 1.12]), and current suicidal ideation (OR = 1.09, 95% CI [1.05, 1.13]), even after conservative adjustment for possible confounding variables. Desirable effects of service predicted significantly lower odds of current suicidal ideation (OR = 0.96, 95% CI [0.93, 0.99]). CONCLUSION: Taken together, results of this study suggest that perceptions of military service are associated with suicidal ideation and other mental health conditions. In addition, assessing veterans' perceptions of their service could be used as a method to identify possible at-risk veterans who may benefit from mental health services and resources. (PsycINFO Database Record PMID- 29172563 TI - Examining the impact of behavioral health encounter dose and frequency on posttraumatic stress symptoms among active duty service members. AB - OBJECTIVE: Several factors may influence the standardized delivery and frequency of behavioral health encounters for posttraumatic stress disorder (PTSD) in active duty military settings, potentially impacting the effectiveness of care. This retrospective analysis evaluated the course of treatment among 884 active duty Army service members in routine outpatient care. METHOD: Patients were included in the analysis based on a screening score of 50 or higher on the PTSD Checklist (PCL-C) at intake. Patients subsequently completed the PCL-C at periodic intervals during behavioral health encounters. A multilevel model predicting PCL-C score was constructed with the number of encounters and days between encounters as predictor variables, controlling for intake PCL-C scores. RESULTS: A higher number of total encounters during the entire study period predicted lower scores on the PCL-C. Quadratic effects showed that encounter frequency of less than 3 weeks and treatment during the first 8 encounters was associated with lower symptoms. A curvilinear effect showed that long breaks in care are associated with greater PTSD symptoms, but also that very-frequent care (e.g., twice weekly) would be associated with greater symptoms. CONCLUSION: These results suggest the need to carefully monitor the frequency and overall dose of behavioral health encounters for PTSD among active duty military patients, suggesting that the greatest treatment gains occur early in treatment and that there is a need for idiographic treatment planning that addresses both the needs of the patient and the mission needs of the military command.

AB - Creativity is highly valued in organizations as an important source of innovation. As most creative projects require the efforts of groups of individuals working together, it is important to understand how creativity is perceived for team products, including how observers attribute creative ability to focal actors who worked as part of a creative team. Evidence from three experiments suggests that observers commit the fundamental attribution error systematically discounting the contribution of the group when assessing the creative ability of a single group representative, particularly when the group itself is not visually salient. In a pilot study, we found that, in the context of the design team at Apple, a target group member visually depicted alone is perceived to have greater personal creative ability than when he is visually depicted with his team. In Study 1, using a sample of managers, we conceptually replicated this finding and further observed that, when shown alone, a target member of a group that produced a creative product is perceived to be as creative as an individual described as working alone on the same output. In Study 2, we replicated the findings of Study 1 and also observed that a target group member depicted alone, rather than with his team, is also attributed less creative ability for uncreative group output. Findings are discussed in light of how overattribution of individual creative ability can harm organizations in the long run. (PsycINFO Database Record PMID- 29172564 TI - Meta-analysis of action video game impact on perceptual, attentional, and cognitive skills. AB - The ubiquity of video games in today's society has led to significant interest in their impact on the brain and behavior and in the possibility of harnessing games for good. The present meta-analyses focus on one specific game genre that has been of particular interest to the scientific community-action video games, and cover the period 2000-2015. To assess the long-lasting impact of action video game play on various domains of cognition, we first consider cross-sectional studies that inform us about the cognitive profile of habitual action video game players, and document a positive average effect of about half a standard deviation (g = 0.55). We then turn to long-term intervention studies that inform us about the possibility of causally inducing changes in cognition via playing action video games, and show a smaller average effect of a third of a standard deviation (g = 0.34). Because only intervention studies using other commercially available video game genres as controls were included, this latter result highlights the fact that not all games equally impact cognition. Moderator analyses indicated that action video game play robustly enhances the domains of top-down attention and spatial cognition, with encouraging signs for perception. Publication bias remains, however, a threat with average effects in the published literature estimated to be 30% larger than in the full literature. As a result, we encourage the field to conduct larger cohort studies and more intervention studies, especially those with more than 30 hours of training. (PsycINFO Database Record PMID- 29172566 TI - An integrated model of academic self-concept development: Academic self-concept, grades, test scores, and tracking over 6 years. AB - Our newly proposed integrated academic self-concept model integrates 3 major theories of academic self-concept formation and developmental perspectives into a unified conceptual and methodological framework. Relations among math self concept (MSC), school grades, test scores, and school-level contextual effects over 6 years, from the end of primary school through the first 5 years of secondary school (a representative sample of 3,370 German students, 42 secondary schools, 50% male, M age at grade 5 = 11.75) support the (1) internal/external frame of reference model: Math school grades had positive effects on MSC, but the effects of German grades were negative; (2) reciprocal effects (longitudinal panel) model: MSC was predictive of and predicted by math test scores and school grades; (3) big-fish-little-pond effect: The effects on MSC were negative for school-average achievement based on 4 indicators (primary school grades in math and German, school-track prior to the start of secondary school, math test scores in the first year of secondary school). Results for all 3 theoretical models were consistent across the 5 secondary school years: This supports the prediction of developmental equilibrium. This integration highlights the robustness of support over the potentially volatile early to middle adolescent period; the interconnectedness and complementarity of 3 ASC models; their counterbalancing strengths and weaknesses; and new theoretical, developmental, and substantive implications at their intersections. (PsycINFO Database Record PMID- 29172567 TI - Parent praise to toddlers predicts fourth grade academic achievement via children's incremental mindsets. AB - In a previous study, parent-child praise was observed in natural interactions at home when children were 1, 2, and 3 years of age. Children who received a relatively high proportion of process praise (e.g., praise for effort and strategies) showed stronger incremental motivational frameworks, including a belief that intelligence can be developed and a greater desire for challenge, when they were in 2nd or 3rd grade (Gunderson et al., 2013). The current study examines these same children's (n = 53) academic achievement 1 to 2 years later, in 4th grade. Results provide the first evidence that process praise to toddlers predicts children's academic achievement (in math and reading comprehension) 7 years later, in elementary school, via their incremental motivational frameworks. Further analysis of these motivational frameworks shows that process praise had its effect on fourth grade achievement through children's trait beliefs (e.g., believing that intelligence is fixed vs. malleable), rather than through their learning goals (e.g., preference for easy vs. challenging tasks). Implications for the socialization of motivation are discussed. (PsycINFO Database Record PMID- 29172568 TI - Tone series and the nature of working memory capacity development. AB - Recent advances in understanding visual working memory, the limited information held in mind for use in ongoing processing, are extended here to examine auditory working memory development. Research with arrays of visual objects has shown how to distinguish the capacity, in terms of the number of objects retained, from the precision of the object representations. We adapt the technique to sequences of nonmusical tones, in an investigation including children (6-13 years, N = 84) and adults (26-50 years, N = 31). For each series of 1 to 4 tones, the participant responded by using an 80-choice scale to try to reproduce the tone at a queried serial position. Despite the much longer-lasting usefulness of sensory memory for tones compared with visual objects, the observed tone capacity was similar to previous findings for visual capacity. The results also constrain theories of childhood working memory development, indicating increases with age in both the capacity and the precision of the tone representations, similar to the visual studies, rather than age differences in time-based memory decay. The findings, including patterns of correlations between capacity, precision, and some auxiliary tasks and questionnaires, establish capacity and precision as dissociable processes and place important constraints on various hypotheses of working memory development. (PsycINFO Database Record PMID- 29172569 TI - The emergence of the empirical stance: Children's testing of counterintuitive claims. AB - Although children often believe an adult's claims, they may have opportunities to check these claims by gathering relevant empirical evidence themselves. Here, we examine whether children seize such opportunities, especially when the claim is counterintuitive. Chinese preschool and elementary schoolchildren were presented with five different-sized Russian dolls and asked to indicate the heaviest doll. Almost all children selected the biggest doll. Half of the children then heard a false, counterintuitive claim (i.e., smallest = heaviest). The remaining children heard a claim confirming their initial intuition (i.e., biggest = heaviest). Children in both age groups typically endorsed the experimenter's claim even when it was counterintuitive. However, during the experimenter's subsequent absence, elementary schoolchildren explored the dolls more if they had received counterintuitive rather than confirming testimony whereas preschool children rarely explored, no matter what testimony they had received. Thus, with increasing age, children seize opportunities to test counterintuitive claims. (PsycINFO Database Record PMID- 29172570 TI - Clarifying the relation of acculturative stress and anxiety/depressive symptoms: The role of anxiety sensitivity among Hispanic college students. AB - OBJECTIVES: Recent work has highlighted the link between acculturative stress and depression/anxiety symptoms among Hispanic young adults, but the nature of these relations is not well understood. The present study aimed to clarify the relation between acculturative stress and depression/anxiety symptoms by examining anxiety sensitivity, globally and via subfactors, as an explanatory variable. METHOD: A cross-sectional sample of 788 Hispanic college students (80.8% female; Mage = 20.83 years, SD = 1.93) was recruited from a southwestern public university and completed an online self-report assessment battery. RESULTS: Acculturative stress exerted an indirect effect, via the global construct of anxiety sensitivity, on depression symptoms, suicidality, anxious arousal, and social anxiety symptoms. Follow-up simultaneous analytic models demonstrated indirect effects via the anxiety sensitivity subfactors that were pathognomonic with each of the specific affective outcomes. CONCLUSIONS: These findings suggest the utility of assessing and targeting anxiety sensitivity in the treatment of acculturative stress related depression/anxiety problems among Hispanic college students. (PsycINFO Database Record PMID- 29172571 TI - Processes underlying Mexican-origin adolescent mothers' BMI. AB - OBJECTIVE: To examine potential mediating and moderating factors in the longitudinal association between contextual stressors (economic hardship, ethnic discrimination) and subsequent engagement in risky behaviors and body mass index (BMI) of Mexican-origin adolescent mothers. METHOD: Participants were Mexican origin adolescent mothers (N = 204) who were recruited from community agencies and high schools in a Southwestern metropolitan area. Contextual stressors and risky behaviors were assessed 3 and 4 years postpartum. Adolescent mothers' BMI was assessed 5-years postpartum. Path analyses assessed moderated mediation with risky behaviors as a mediator of associations between contextual stressors and BMI, and family and friend support as moderators of the mediated pathways. RESULTS: At low levels of family support, economic hardship at 3-years postpartum positively predicted engagement in risky behaviors at 4-years postpartum, which in turn positively predicted BMI at 5-years postpartum. At high levels of family support, all relations were not significant. At low levels of friend support, ethnic discrimination at 3-years postpartum positively predicted engagement in risky behaviors at 4-years postpartum, which in turn positively predicted BMI at 5-years postpartum. At high levels of friend support, all relations were not significant. CONCLUSIONS: Among adolescent mothers who receive low levels of family and friend support, engagement in risky behaviors may function as a mechanism through which contextual stressors are linked to adolescent mothers' BMI. Findings have implications for prevention efforts aimed at attenuating unhealthy weight status among Mexican-origin adolescent mothers by reducing engagement in risky behaviors and bolstering family and friend support. (PsycINFO Database Record PMID- 29172572 TI - A narrative approach to the role of others in ethnic identity formation. AB - OBJECTIVES: The aim of the present study was to explore the role of others in ethnic identity development. Three questions were asked: to what extent others are involved in these processes, what roles they play, and whether the roles differed between participant who identified with a majority, minority or mixed ethnic identity. METHOD: An exploratory, narrative approach was used, and written narratives were analyzed both qualitatively and quantitatively. The analytic sample consisted of 191 participants (78% female, Mage = 20.39, SD = 5.31), of which 64% identified as Swedish, 11% as another ethnicity, and 25% as Swedish/other ethnicity. RESULTS: Results showed that others were present in most of the ethnicity-defining experiences and most participants expressed a self defined ethnic identity. A thematic analysis of the role of others resulted in 6 themes; others as contrast, as reference, raising awareness, accepting, ascribing, and denying. Most commonly, others functioned as a contrast and/or a reference point that the narrators could position themselves against. Participants with mixed majority/minority identities more often experienced that others ascribed or denied them their ethnic identities. CONCLUSIONS: The current findings lend empirical support for ethnic identity formation as an interactive process and for the role of others in these processes. A power imbalance was prevalent throughout the results, where the degree of looking and acting "Swedish enough" limited the power of choosing an identity. In multicultural societies, for people to have the power to define and have their ethnic identities accepted is a necessary condition for integration. (PsycINFO Database Record PMID- 29172573 TI - Profiles of culturally salient positive parenting practices among urban-residing Black Head Start families. AB - OBJECTIVES: To better understand within-group variability in positive parenting practices among low-income Black families, the present study, grounded in a multidimensional comparative framework, examined (a) patterns of positive parenting practices among U.S.-born African American parents and Black Caribbean immigrant parents and (b) the extent to which these patterns related to parents' daily family social support, parents' social sensitivities, and children's social emotional outcomes. METHOD: A person-oriented approach was employed with data from 524 African American and Black Caribbean immigrant parents (mothers, fathers, grandparents, aunts/uncles) of preschool-aged children in Head Start. RESULTS: Multistage hierarchical cluster analysis revealed that although the best solution for both ethnic groups was a 5-profile solution, the particular profiles that emerged across the 2 groups were distinct. Further, different parenting practices were salient among the 'high positive parenting' profiles and 'low positive parenting' for African Americans and Caribbean immigrants. In addition, demographic factors (education, gender, and marital status) differentially related to patterns of positive parenting across the 2 ethnic groups, and these patterns of parenting were associated with children's social emotional development and parenting resources in meaningful ways. CONCLUSIONS: Findings underscore the importance of conducting within-group studies that examine variability across ethnocultural groups identified as belonging to the same racial group. Indeed, there was variation in the manifestations of positive parenting within and across the ethnic groups included in this study (i.e., African Americans and Caribbean immigrants) that can inform future research and practice. (PsycINFO Database Record PMID- 29172574 TI - Gender and violence risk assessment in prisons. AB - Our study examines the association between Historical, Clinical, Risk Management 20: Version 2; Psychopathy Checklist-Revised; and Violence Risk Assessment Guide scores and violence perpetrated during incarceration by male and female inmates. Using a sample of 288 men and 183 women selected from prisons in 2 states, we used receiver operating characteristics analyses to assess the potential of these 3 measures to predict threatened, physical, or sexual prison violence measured in 2 ways: inmate self-report and formal institutional infractions. We found all 3 instruments to demonstrate moderate to good levels of predictive accuracy for both the male and female inmates, a finding that suggests that actuarial, structured professional judgment and personality measures perform in a broadly comparable manner in assessing institutional violence for both men and women. Our findings did vary on the basis of the way violence was measured: Women self reported significantly higher levels of prison violence than was suggested by their institutional infractions, and the associative power of the instruments diminished substantially, particularly among the men, when institutional infractions alone were used in the analyses. These findings suggest that the 3 risk measures are likely to be gender neutral in their association with prison violence, albeit with gender-related differences in the frequency of violent behavior and the relevance of particular subscales.

PMID- 29172575 TI - 125th anniversary of the American Psychological Association-Accomplishments and challenges: Introduction to the special issue. AB - In 2017, the American Psychological Association (APA) celebrates the 125th anniversary of its founding. This special issue commemorates this milestone by providing long- and short-term views on the history of APA and its role in psychology in America. The opening paper presents an overview of initiatives and challenges facing the field of psychology and APA in five periods, each roughly 25 years in length. The remaining eight articles review specific issues and areas of activity over varying lengths of time in more recent years. Issues of policy involvement, relations with the media, and involvement with the courts are described, as well as developments related to social justice, education, science, practice, and publications. (PsycINFO Database Record PMID- 29172576 TI - 125 years of the American Psychological Association. AB - The American Psychological Association (APA) began 125 years ago as a small club of a few dozen members in the parlor of its founder, G. Stanley Hall. In the decades since, it has faced many difficulties and even a few existential crises. Originally a scientific society, it spent the decades between the world wars figuring out how to accommodate the growing community of applied psychologists while still retaining and enhancing its scientific reputation. After World War II, with an expanded mandate, it developed formal training models for clinical psychologists and became an important player in legal cases pertaining to civil rights and other social justice issues. With practitioners taking an ever-greater role in the governance of the organization in the late 1970s, and the financial viability of the association in doubt in the 1980s, many psychological scientists felt the need to create a separate organization for themselves. The 1990s and early 2000s brought more challenges: declining divisional memberships; a legal dispute over fees with practitioners; and a serious upheaval over the APA Board of Directors' cooperation with governmental defense and intelligence agencies during the "war on terror." These clashes appear to have precipitated a decline in the association's membership for the first time in its history. The APA has faced many storms over its century-and-a-quarter, but has, thus far, always ultimately found a way forward for itself, for its members, and for the wider discipline of psychology. (PsycINFO Database Record PMID- 29172577 TI - Psychology, public policy, and advocacy: Past, present, and future. AB - This article offers a historical perspective on the contributions of the field of psychology and the American Psychological Association (APA) to the public policy arena. It traces APA's involvement from a 1956 Council of Representatives resolution on the application of psychology to inform public policy to current advocacy initiatives related to psychological science, practice, and education in the public interest. Attention is directed to APA's early policy structures together with the development of affiliated state, provincial, and territorial psychological associations and the first political action committee for psychology. The criteria for engagement in advocacy and the goals and functions of APA's policy and advocacy initiatives, including the APA Congressional and Executive Branch Science Fellowship Program, are also discussed. The evolution of psychology's public policy role is illustrated by an increasing level of federal advocacy engagement and effectiveness over time, as well as by the emergence of psychology leaders in Congress and the Executive Branch. The authors' concluding reflections on the future of psychology in the public policy arena derive from their many years of experience working on or with Capitol Hill, at APA as elected officials or senior staff, and in various roles in academia, think tanks, service delivery, and the private sector. (PsycINFO Database Record PMID- 29172578 TI - APA's amicus curiae program: Bringing psychological research to judicial decisions. AB - An important part of the American Psychological Association's (APA) mission is to advance psychological science "to promote health, education, and public welfare." Organizations with powerful influence on human welfare include state and federal appellate courts, especially the U.S. Supreme Court. Initially, APA's amicus briefs focused on issues of importance to both individual psychologists and public policy. As the program evolved, APA increasingly focused on informing the courts about psychological science relevant to important legal issues, including criminal, civil, juvenile, education, disability, and human rights law. These briefs, and the science that supported them, consistently challenged stereotypical beliefs of laypeople with solid, easily understood empirical research. APA impartially advocates for the use of psychological science research findings by the courts, not on behalf of parties. Volunteer experts, including representatives of relevant APA divisions, participate in creating APA briefs. On occasion, other scientific organizations may join with APA in its filings. The measure of an amicus brief is broader than citations in appellate decisions. Although APA's briefs have been cited many times by courts, a broader impact of APA briefs is seen by references to psychosocial research provided by APA in decisions where its briefs were not specifically cited. APA briefs are being read and are affecting major legal decisions. For APA, the relevant question is not whether its briefs "prevailed" in a case but whether the court was able to render a more informed decision. An important benefit of APA's amicus program has been advancing both the reputation of psychological science and APA. (PsycINFO Database Record PMID- 29172579 TI - Public education and media relations in psychology. AB - This article reviews psychology's attempts to influence public attitudes about both the science and the profession of psychology. The early history of the profession is reviewed, and the efforts of the American Psychological Association (APA) to shape the public's perception of psychology are discussed. The rise of social media is reviewed, and important social media outlets relevant to psychology are identified. The activities of the Society for Media Psychology and Technology (APA Division 46) are illustrated, and the presidents of the Division are identified. The work of those psychologists who are noted public intellectuals or who have received Nobel prizes or National Medal of Science awards for their research is briefly reviewed, and the public notoriety of 4 prominent media celebrities (Joy Browne, Joyce Brothers, Laura Schlessinger, and Phil McGraw) is discussed. Several controversies in the field of psychology that have influenced the public and their attitudes about psychology are also briefly reviewed. (PsycINFO Database Record PMID- 29172580 TI - APA efforts in promoting human rights and social justice. AB - This article reviews the American Psychological Association's (APA) efforts in promoting human rights and social justice. Beginning with a historical review of the conceptualizations of human rights and social justice, the social challenges that have faced the United States over time are discussed in relation to the APA's evolving mission and strategic initiatives enacted through its boards, committees, and directorates. From early efforts on the Board for Social and Ethical Responsibility in Psychology and the Board of Ethnic Minority Affairs to the establishment of the Public Interest Directorate, the APA's efforts to address these human rights and social justice challenges through its task force reports, guidelines, and policies are described. Specifically, issues related to diversity and underrepresentation of minority group members and perspective within the APA, as well as women's issues (prochoice, violence against women, sexualization of young girls, human trafficking) were central to these efforts. These minority groups included racial and ethnic minority groups; immigrants and refugees; lesbian, gay, bisexual, transgendered, and queer individuals; and those with disabilities. Later attention shifted to broader social justice challenges within a public health perspective, such as AIDS, obesity, and violence. Also included is a brief discussion of the Hoffman Report. The article ends with a discussion of future directions for the APA's efforts related to human rights and social justice related to health disparities, violent extremism, social inequality, migration, cultural and racial diversity, and an evidence-based approach to programming. (PsycINFO Database Record PMID- 29172581 TI - Twenty-five years of education in psychology and psychology in education. AB - This article is part of a special issue of the American Psychologist celebrating the American Psychological Association's (APA's) 125th anniversary. The article reviews the last quarter century (1991-2016) of accomplishments by psychology's education and training community and APA's Education Directorate. The purpose is to highlight key trends and developments over the past quarter century that illustrate ways the Directorate sought to advance education in psychology and psychology in education, as the Directorate's mission statement says. The focus of the Directorate has been on building a cooperative culture across psychology's broad education and training community. Specifically APA has (a) promoted quality education-from prekindergarten through lifelong learning, (b) encouraged accountability through guidelines and standards for education and training, and (c) supported the discovery and dissemination of new knowledge to enhance health, education, and well-being. After identifying challenges and progress, the article discusses the future of the field of psychology and the preparation of its workforce of tomorrow. (PsycINFO Database Record PMID- 29172582 TI - NIH behavioral and social sciences research support: 1980-2016. AB - The history of behavioral and social science research funding at the National Institutes of Health (NIH) between 1980 and 2016 is reviewed. Noncommunicable diseases are now the primary cause of death worldwide and most are strongly linked to behavior. Developed under the prevailing zeitgeist of the biomedical model, behavioral and social science has often been underfunded at NIH. In 1990, the Senate Appropriations Committee, recognizing that behavior may contribute to about half of all premature deaths, recommended that funding for behavioral and social sciences research should be about 10% of the NIH budget. NIH and American Psychological Association efforts to address this goal are described. Data from several sources suggest that this goal has never been realized. Patterns of federal funding for research may have a significant influence on scientific disciplines. Fields of study that have received more extramural funding are associated with greater growth in faculty and higher faculty salaries. A renewed effort to increase the federal investment in behavioral and social sciences research is necessary. (PsycINFO Database Record PMID- 29172583 TI - A quarter century of psychological practice in mental health and health care: 1990-2016. AB - Powerful forces have shaped professional psychology over the past 25 years, including significant changes in health policy and health care delivery systems. Examples include managed care cost containment, rapid growth of nondoctoral mental health providers, federal mental health parity legislation, and passage of the Affordable Care Act of 2010, with its emphasis on primary care-behavioral health integration and alternatives to fee-for-service reimbursement. This article considers these factors for psychology as a mental health profession and as a health profession more broadly defined, and describes the American Psychological Association's advocacy about the value of psychology in each domain. While challenging to psychology's traditional models of care, these changes offer significant promise for the future of psychology in health care. (PsycINFO Database Record PMID- 29172584 TI - From print to digital (1985-2015): APA's evolving role in psychological publishing. AB - Knowledge dissemination plays an important role in all scientific fields. The American Psychological Association's (APA) journal publication program was established in 1927. During the 1960s, the Psychological Abstracts publication was computerized. In the mid-1980s, a reenergizing of APA Publishing began, with the establishment of the APA Books Program, as well as the movement of abstracts to CD-ROMs. This article describes the 30-year program of expansion of APA Publishing, covering the period from 1985 through 2015. This period saw the journals program grow from 15 journals to 89 journals, the abstract program grow into an Internet-based delivery system, the creation of the APA's own PsycNET delivery platform, the creation of 6 addition databases, and the establishment of dictionaries and handbooks of psychology. (PsycINFO Database Record PMID- 29172585 TI - An eye-tracking examination of readers' sensitivity to pragmatic scope information during the processing of conditional inducements. AB - Previous research into conditional inducements has shown that readers are sensitive after reading such conditionals to pragmatic scope differences between promises and threats; specifically, threats can be referred to as promises, but promises cannot be referred to as threats. Crucially, previous work has not revealed whether such scope effects emerge while processing the conditional itself. In the experiment reported here, participants' eye movements were recorded while they read vignettes containing conditional promises and threats. We observed a reading time penalty on the conditional itself when participants read a conditional promise that was described as a "threat" (e.g., Liam threatened Perry "if you tell dad, then I'll take equal responsibility"). There was no such penalty when the word "promise" was presented before a conditional threat. These results suggest that readers are sensitive during reading of the conditional itself to pragmatic scope differences between "threats" and "promises." (PsycINFO Database Record PMID- 29172586 TI - Alpha span: A measure of working memory. AB - In the alpha span test, short lists of words are presented and the participant's task is to mentally reorder the words and give them back in correct alphabetical order. Alpha span is the longest list of words correctly recalled; the article also describes a scoring method in which credit is given for partially correct answers. Alpha span provides a quick and easily completed measure of verbal numerical working memory (WM), and evidence is presented to show that it is also a valid and reliable measure. One purpose of the article is to present data on age-related differences in WM in participants 17 to 87 years of age. These data show that alpha span is highest in people in their 20s and then declines systematically from the 20s to the 80s. A 2nd purpose is to report data on the reliability of the alpha span measure and explore its relationships with other cognitive measures. The article concludes with some comments on the nature of WM as illustrated by alpha span; specifically, we suggest that WM reflects both domain-general executive functions and specific abilities in the domain tapped by the task in question. (PsycINFO Database Record PMID- 29172587 TI - Entrainement de la memoire de travail : Effets sur la performance en mathematiques. AB - The main components of working memory (WM; Baddeley & Hitch, 1974), central executive, phonological loop and visuospatial sketchpad, are related to mathematics skills (Friso-van den Bos, Van der Ven, Kroesbergen, & Van Luit, 2013). Different studies have shown that WM training can increase WM capacity (Randall & Tyldesley, 2016). In that context, this research seeks to verify the effects of WM training on the components of WM as well as on performance in arithmetic and in problem solving among students in the first grades of primary school (6 to 8 years of age). The project also seeks to verify whether improvements are maintained over a six-month period and whether the training has a differential effect in mathematics depending on initial WM capacities. The results of this randomized and controlled study indicate that only central executive capacities are improved by WM training. Gains in verbal modality tend to be maintained over six months while visuo-spatial improvement does not. There was no observable effect on mathematic skills. However, WM training has a differential effect on problem solving, since children who had low initial WM performance did improve their problem solving performance. In conclusion, the effects of WM training are specific, generally to the central executive, and differentially to problem solving skills among those students with lower WM capacities. (PsycINFO Database Record PMID- 29172588 TI - Things can change: Sentence processing in consecutive translation. AB - Syntactic cues help individuals to assign thematic roles (agent/patient) during sentence processing. In the present study, we examined whether the use of syntactic cues changed in bilinguals depending on the task they performed. Spanish (L1)/English (L2) bilinguals read sentences in Spanish either to produce them in the same language or to translate them in English. Three syntactic cues were evaluated: animacy (Experiment 1), subject-verb agreement (Experiment 2), and word order (Experiment 3). In Experiments 1 and 2, word order was stronger than animacy and subject-verb agreement when bilinguals read for translation. Moreover, when the same syntactic cue favoured a different agent for each language (word order in Experiment 3), the bilinguals performed as native speakers of Spanish in the within-language task, whereas they performed as native speakers of English in the translation task. Together, this research indicates that translation changes the way bilinguals use syntactic cues in sentence processing. (PsycINFO Database Record PMID- 29172589 TI - Disentangling the link between posttraumatic stress disorder and violent behavior: Findings from a nationally representative sample. AB - OBJECTIVE: Although research using combat veteran samples has demonstrated an association between posttraumatic stress disorder (PTSD) and violence toward others, there has been relatively little research examining this relationship among individuals with no combat history. METHOD: Data representative of the United States population collected from the two wave National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were analyzed to determine the risk factors for violent behavior of individuals reporting no history of active military combat (N = 33,215). RESULTS: In chi2 analyses, participants meeting criteria for lifetime PTSD at Wave 1 reported higher rates of violence between Waves 1 and 2 compared with participants without a history of PTSD (7 vs. 3%). An increase in anger after trauma and use of alcohol to cope with PTSD symptoms were stronger predictors of physically aggressive or violent acts than a lifetime diagnosis of PTSD without anger. When controlling for these and other covariates, PTSD alone no longer significantly predicted any subtype of physical aggression or violence toward others. CONCLUSIONS: Results suggest that although PTSD is related to violent behavior, specific sequelae of trauma (specifically, increased anger and self-medicating with alcohol) are more critical than diagnosis per se in predicting violent behavior in the general population. Clinical implications and future research directions are discussed. (PsycINFO Database Record PMID- 29172590 TI - The mediating effect of family cohesion in reducing patient symptoms and family distress in a culturally informed family therapy for schizophrenia: A parallel process latent-growth model. AB - OBJECTIVE: Although both patients with schizophrenia and their caregivers report elevated levels of depression, anxiety, and stress (DASS), affective symptoms in patients and family members seldom constitute a primary treatment focus. The present study tested whether a culturally informed family therapy for schizophrenia (CIT-S) outperformed standard family psychoeducation (PSY-ED) not only in decreasing patient schizophrenia symptoms, but also in decreasing individual DASS. Because CIT-S fostered family cohesion throughout treatment, we predicted that increases in family cohesion would mediate treatment effects. METHOD: Participants included 266 patients and family members nested within 115 families, randomized to the CIT-S or PSY-ED conditions. We specified a series of multilevel latent growth and latent change models to examine direct effects of CIT-S on patient schizophrenia symptoms, individual DASS, and family cohesion over time. Next, we used parallel-process growth models to test the indirect effect of CIT-S on decreasing patient and caregiver psychopathology over time via changes in family cohesion. RESULTS: The CIT-S treatment significantly reduced patient schizophrenia symptoms from baseline to follow-up (gamma = -1.72, 95% confidence interval [CI] [-2.83, -0.60]), as well as individual DASS (gamma = 4.39, 95% CI [-6.44, -2.34]) from baseline to termination. In line with treatment goals, CIT-S increased family cohesion from baseline to midpoint (gamma = 0.93, 95% CI [0.06, 1.80]). The CIT-S-related change in cohesion mediated changes in DASS (gamma = -0.87, 95% CI [-1.47, -0.27]), but not patient symptoms. CONCLUSION: By integrating the family's cultural context into treatment, clinicians may foster family dynamics that enhance treatment outcomes and promote broad improvements in mental health. (PsycINFO Database Record PMID- 29172591 TI - A prospective investigation of the synergistic effect of change in anxiety sensitivity and dysphoria on tobacco withdrawal. AB - OBJECTIVE: Prevailing theory and research suggests the psychological and physiological discomfort associated with tobacco withdrawal may play a formative role in the risk of cessation failure. Yet, research elucidating cognitive affective vulnerability characteristics that contribute to increased tobacco withdrawal severity during periods of planned abstinence is highly limited. In the current study, we explored whether smokers with greater reductions of Anxiety Sensitivity (AS) and dysphoria during a smoking cessation intervention would experience less severe postquit tobacco withdrawal. METHOD: Specifically, the interactive effect of change (from preintervention baseline to quit day) in AS and dysphoria in relation to postquit withdrawal severity (quit day through 12 weeks postquit) was examined among treatment-seeking adult smokers enrolled in a smoking cessation trial (N = 198; 55.3% female; 86.8% Caucasian; Mage = 38.8, SD = 14.0). RESULTS: Results indicated that the interactive effect of change in AS and dysphoria was related to linear change in postquit withdrawal symptoms. Specifically, larger reductions in AS were associated with a faster decline in the severity of withdrawal symptoms across the 12-week postquit period only for individuals with lower (but not higher) reductions in dysphoria. Additionally, the findings indicated that reducing levels of AS and dysphoria prequit is broadly related to the degree of change in postquit withdrawal symptoms. CONCLUSION: Collectively, these data suggest there is apt to be clinical merit to employing strategies to address AS and/or dysphoria to more effectively manage emergent withdrawal symptoms following smoking cessation treatment. (PsycINFO Database Record PMID- 29172593 TI - Internet-based cognitive behavioral therapy versus psychoeducation control for illness anxiety disorder and somatic symptom disorder: A randomized controlled trial. AB - OBJECTIVE: To examine the efficacy of an Internet-delivered cognitive-behavioral therapy (iCBT) program for health anxiety compared to an active psychoeducation control group. METHOD: Individuals (N = 86, mean age: 30 years, 87% female) with a Diagnostic and Statistical Manual of Mental Disorders (5th ed.) diagnosis of illness anxiety disorder or somatic symptom disorder with health anxiety were randomized to either a 6-lesson clinician-guided iCBT program for health anxiety (n = 45) or an active control group who received anxiety psychoeducation, clinical support, and monitoring (control, n = 41) over a 12-week period. RESULTS: Both groups experienced significant improvements between baseline and posttreatment on self-report measures of health anxiety, depression, general anxiety, and functional impairment. Intention-to-treat analyses indicated that the iCBT group experienced greater improvements in health anxiety on the Short Health Anxiety Inventory (SHAI) compared to controls (between-groups effect size = 1.39, 95% confidence interval [0.87, 1.93]), and a greater proportion of the iCBT group showed clinically reliable change on the SHAI (84% vs. 34% in the control group). Similarly, the iCBT group outperformed the control group on secondary measures of depression, generalized anxiety, functional impairment, maladaptive cognitions, body hypervigilance, safety behaviors and avoidance, and intolerance of uncertainty. Gains were maintained at 3-month follow-up in the iCBT group. CONCLUSION: iCBT for health anxiety is more effective than psychoeducation, clinical support, and monitoring, and presents an efficacious and accessible treatment option for people with health anxiety. (PsycINFO Database Record PMID- 29172592 TI - Non-suicidal self-injury and suicidal thoughts and behaviors: A study of the explanatory roles of the interpersonal theory variables among military service members and veterans. AB - OBJECTIVE: Research has identified non-suicidal self-injury (NSSI) as a robust correlate of suicidal thoughts and behaviors; however, little is known regarding why these constructs may be related. Consistent with the interpersonal theory of suicide, this study investigated thwarted belongingness (TB), perceived burdensomeness (PB), and capability for suicide (CS) as explanatory links in the association between NSSI, ideation, and suicide attempt history. METHOD: Military service members and veterans (N = 973; agemean = 29.9 years, 78.8% male, 63.8% Caucasian/White) completed measures of lifetime NSSI and suicide attempts; current suicidal ideation; TB, PB, and CS; and related psychiatric symptoms. Bootstrap moderated mediation analyses were employed to examine whether (a) TB moderated the mediating effect of PB on NSSI and ideation, (b) PB moderated the mediating effect of TB on NSSI and ideation, and (c) CS moderated the mediating effect of TB and PB on NSSI and attempts. RESULTS: TB and PB significantly accounted for the relationship between lifetime NSSI and current ideation. TB did not moderate the mediating effect of PB on NSSI and ideation, and PB did not moderate the mediating effect of TB. However, CS significantly moderated the mediating effects of TB and PB on NSSI and attempt history. CONCLUSIONS: The interpersonal theory of suicide hypotheses were partially supported. Consistent with the theory, the interaction of TB and PB only explained NSSI and attempt history among service members with high levels of CS. TB and PB only individually explained the association between lifetime NSSI and recent suicidal ideation. Prospective studies are warranted to replicate these findings across other military samples. (PsycINFO Database Record PMID- 29172594 TI - Trajectories of in-session change language in brief motivational interventions with mandated college students. AB - OBJECTIVE: Brief motivational interventions (BMIs) are currently the most efficacious individual intervention for mandated college students. However, little is known about how BMIs facilitate client language in relation to subsequent changes in alcohol use and problems in mandated student samples. METHOD: The current study used the Motivational Interviewing Skills Code (MISC 2.0; Miller, Moyers, Ernst, & Amrhein, 2003) to code BMI sessions (N = 252) from 2 randomized clinical trials that led to significant reductions in alcohol use and alcohol-related problems in mandated student drinkers. A proportion of change language was calculated for each decile (1st to 10th) of the BMI sessions. RESULTS: Latent class analyses of in-session speech indicated that there were 3 distinct trajectories of change language over the course of the session: high (n = 59), increasing (n = 122), and low (n = 71). Members of the high trajectory group showed higher rates of alcohol-related problems prior to the BMI and members of the low trajectory group were more likely to be male. Six months following the BMI, members of the high and low trajectory groups demonstrated significant reductions in alcohol use and problems, and members of the increasing trajectory group only reduced alcohol-related problems. CONCLUSIONS: Associations among the 3 trajectories of client change language and subsequent reductions in alcohol use and problems partially supported the technical hypothesis of MI efficacy. Client factors as well as the nature of the discussion of personalized feedback may determine the link between in-session client language and subsequent behavior change. (PsycINFO Database Record PMID- 29172595 TI - Mental health treatment patterns following screening at intake to prison. AB - OBJECTIVE: While there is general consensus about the need to increase access to mental health treatment, it is debated whether screening is an effective solution. We examined treatment use by inmates in a prison system that offers universal mental health screening. METHOD: We conducted an observational study of 7,965 consecutive admissions to Canadian prisons. We described patterns of mental health treatment from admission until first release, death, or March, 2015 (median 14-month follow-up). We explored the association between screening results and time of first treatment contact duration of first treatment episode, and total number of treatment episodes. RESULTS: Forty-three percent of inmates received at least some treatment, although this was often of short duration; 8% received treatment for at least half of their incarceration. Screening results were predictive of initiation of treatment and recurrent episodes, with stronger associations among those who did not report a history prior to incarceration. Half of all inmates with a known mental health need prior to incarceration had at least 1 interruption in care, and only 46% of inmates with a diagnosable mental illness received treatment for more than 10% of their incarceration. CONCLUSION: Screening results were associated with treatment use during incarceration. However, mental health screening may have diverted resources from the already known highest need cases toward newly identified cases who often received brief treatment suggestive of lower needs. Further work is needed to determine the most cost-effective responses to positive screens, or alternatives to screening that increase uptake of services. (PsycINFO Database Record PMID- 29172596 TI - Overcoming the research-to-practice gap: A randomized trial with two brief homework and organization interventions for students with ADHD as implemented by school mental health providers. AB - OBJECTIVE: To evaluate the effectiveness of 2 brief school-based interventions targeting the homework problems of adolescents with attention deficit/hyperactivity disorder (ADHD)-the Homework, Organization, and Planning Skills (HOPS) intervention and the Completing Homework by Improving Efficiency and Focus (CHIEF) intervention, as implemented by school mental health providers during the school day. A secondary goal was to use moderator analyses to identify student characteristics that may differentially predict intervention response. METHOD: Two-hundred and eighty middle school students with ADHD were randomized to the HOPS or CHIEF interventions or to waitlist, and parent and teacher ratings were collected pre, post, and at a 6-month follow-up. RESULTS: Both interventions were implemented with fidelity by school mental health providers. Participants were pulled from elective periods and sessions averaged less than 20 min. Participants in HOPS and CHIEF demonstrated significantly greater improvements in comparison with waitlist on parent ratings of homework problems and organizational skills and effect sizes were large. HOPS participants also demonstrated moderate effect size improvements on materials management and organized action behaviors according to teachers. HOPS participants made significantly greater improvements in parent- and teacher-rated use of organized actions in comparison with CHIEF, but not on measures of homework problems. Moderation analyses revealed that participants with more severe psychopathology and behavioral dysregulation did significantly better with the HOPS intervention as compared to the CHIEF intervention. CONCLUSIONS: Brief school-based interventions implemented by school providers can be effective. This type of service delivery model may facilitate overcoming the oft cited research-to practice gap.

AB - Reports an error in "A longitudinal person-centered perspective on youth social support: Relations with psychological wellbeing" by Joseph Ciarrochi, Alexandre J. S. Morin, Baljinder K. Sahdra, David Litalien and Philip D. Parker (Developmental Psychology, 2017[Jun], Vol 53[6], 1154-1169). In the article, the approach utilized (and illustrated in the authors' online supplements) for tests of distributional similarity conducted in the context of Latent Transition Analyses (LTA) is suboptimal, and has been recently optimized in a webnote prepared by Morin and Litalien (2017). This webnote should be consulted by anyone thinking to rely on similar methodologies in the LTA context. Importantly, distributional similarity was not supported in Ciarrochi et al. (2017) using either the initial or optimized method, so that the application of the optimized method results in no change in the reported results. As part of this correction, the online supplemental materials have been updated to direct readers to the webnote. The reference for the Morin and Litalien (2017) webnote is included in the erratum. (The following abstract of the original article appeared in record 2017-17082-001.) Past research suggests that perceived social support from parents, teachers, and peers are all positively associated with wellbeing during adolescence. However, little longitudinal research has examined the implications of distinctive combinations of social support for developing adolescents. To address this limitation, we measured multiple dimensions of social support, psychological ill-health, and wellbeing in a sample of 2034 Australian adolescents (Mage = 13.7; 49.6% male) measured in Grades 8 and 11. Latent transition analyses identified a 6-profile solution for both waves of data, and revealed substantial inequality in perceived social support. Two "socially rich" profiles corresponded to 7% of the sample and had high social support (>1SD above sample mean) from at least two sources. (Fully Integrated; Parent and Peer Supported). In contrast, 25% of the sample was "socially poor," having support that was between -.65 to -.86 SD below the sample mean for all 3 sources (Isolated profile). None of the other profiles (Peer Supported; Moderately Supported; Weakly Supported) had levels of support below -.37 SD from any source. Furthermore, almost all wellbeing problems were concentrated in the Isolated Profile, with negative effects more pronounced in Grade 11 than Grade 8. Despite feeling low parent and teacher support, adolescents in the Peer Supported profile felt strong peer support and average to above-average levels of wellbeing in Grades 8 and 11. However, they also had an 81% chance of making a negative transition to either the Isolated or Weakly Supported profiles in Grade 11. (PsycINFO Database Record PMID- 29172598 TI - Biological underpinnings of an internalizing pathway to alcohol, cigarette, and marijuana use. AB - There is a limited understanding as to how specific genes impact addiction risk. Applying a developmental framework and research domain criteria (RDoC) to identify etiological pathways from genetic markers to addiction may have utility. Prior research has largely focused on externalizing pathways to substance use. Although internalizing mechanisms have received less attention, there is strong support that addiction is a longer term consequence of using substances to cope with internalizing as well as externalizing problems. This study tests whether temperament and depression mediate the association between specific genetic variants and substance use. The sample consisted of 426 adolescents from the Michigan Longitudinal Study (70.9% boys, 84.0% White). Four specific genetic variants were examined: SLC6A4 (5HTTLPR), BDNF (rs6265), NPY (rs3037354), and CRHBP (rs7728378). Childhood resiliency and behavioral control were examined as potential mediators, in addition to early adolescent depression, using a multiple mediator path model. Resiliency and depression were supported as mediators in the association between genetic risk and later substance use. Important differences emerged across substances of abuse. Indirect effects via depression were not significant with the inclusion of aggression. Early difficulties with emotional coping may represent nonspecific neurobiological underpinnings for an internalizing pathway to addiction. (PsycINFO Database Record PMID- 29172599 TI - Negative cognitive style interacts with negative life events to predict first onset of a major depressive episode in adolescence via hopelessness. AB - The hopelessness theory of depression is a prominent account of depression that posits that individuals with a negative inferential style are more likely to become hopeless when they experience negative life events (NLEs) and that hopelessness is a proximal cause of depression. There is strong evidence supporting the role of a negative inferential style in the pathogenesis of major depression; however, substantially less is known about the proposed role played by hopelessness. The cornerstone hypothesis of hopelessness theory, that hopelessness is a proximal cause of major depression, is largely untested. A small number of studies have generated inconclusive evidence that hopelessness mediates the relationship between a negative inferential style, NLEs, and depressive symptoms. The current study tested whether hopelessness mediates the relationship between a Negative Inferential Style * NLEs interaction and (a) 1st onset of a major depressive episode (MDE) and (b) depressive symptoms in a fully prospective design. A diverse sample of 249 adolescents, ages 12-13 years, were assessed at baseline and at 2 or more follow-ups over approximately 2.5 years. Self-report as well as life event and diagnostic interviews assessed inferential style, NLEs, hopelessness, depressive symptoms, and depression diagnosis. Moderated mediation analyses indicated that hopelessness mediated the relationship between a Negative Inferential Style * NLEs interaction and (a) 1st onset of an MDE as well as (b) depressive symptoms at higher levels of multiple types of NLEs. The current study demonstrates the validity of the hopelessness theory of depression and its continued clinical relevance in predicting depression in adolescence. (PsycINFO Database Record PMID- 29172600 TI - What features of psychopathy might be central? A network analysis of the Psychopathy Checklist-Revised (PCL-R) in three large samples. AB - Despite a wealth of research, the core features of psychopathy remain hotly debated. Using network analysis, an innovative and increasingly popular statistical tool, the authors mapped the network structure of psychopathy, as operationalized by the Psychopathy Checklist-Revised (PCL-R; Hare, 2003) in two large U.S. offender samples (nNIMH = 1559; nWisconsin = 3954), and 1 large Dutch forensic psychiatric sample (nTBS = 1937). Centrality indices were highly stable within each sample, and indicated that callousness/lack of empathy was the most central PCL-R item in the 2 U.S. samples, which aligns with classic clinical descriptions and prototypicality studies of psychopathy. The similarities across the U.S. samples offer some support regarding generalizability, but there were also striking differences between the U.S. samples and the Dutch sample, wherein the latter callousnesss/lack of empathy was also fairly central but irresponsibility and parasitic lifestyle were even more central. The findings raise the important possibility that network-structures do not only reflect the structure of the constructs under study, but also the sample from which the data derive. The results further raise the possibility of cross-cultural differences in the phenotypic structure of psychopathy, PCL-R measurement variance, or both. Network analyses may help elucidate the core characteristics of psychopathological constructs, including psychopathy, as well as provide a new tool for assessing measurement invariance across cultures. (PsycINFO Database Record PMID- 29172601 TI - Reciprocal variations in sleep and drinking over time among heavy-drinking young adults. AB - Prior studies have established an association between sleep problems during early adolescence and heavy alcohol use/alcohol use disorder (AUD) risk in late adolescence. Less research has explored the association between sleep problems and heavy alcohol use during young adulthood, the period when AUD onset peaks. Moreover, research to date has primarily utilized cross-sectional, between subjects' methods to examine this relationship, with limited focus on the potential intraindividual variation in these behaviors. Multilevel modeling techniques are well-suited to examine the variability in sleep problems and risky alcohol use over time and the dynamic bidirectional relations among these behaviors. This article reports on 42 heavy-drinking college students at-risk for an AUD based on their responses to a validated alcohol screener who completed daily diaries of sleep and alcohol use and wore a sleep-wake activity monitor (i.e., Philips Respironics Actiwatch 2TM) daily for 7 days yielding a total of 294 reports. Hierarchical linear models demonstrated that days of heavy drinking predicted delayed bed and wake times within individuals and those individuals who tended to drink more heavily on average had shorter sleep durations. Conversely, days of shorter sleep duration, earlier wake times, and greater perceived sleep quality upon waking predicted greater alcohol use within individuals, and those who tended to feel more alert upon waking drank more on average. These results highlight important within- and between-person variability in the associations among objective and subjective sleep-related problems and at-risk drinking among young adults. Further, the results have implications for alcohol prevention/intervention strategies for young adults at risk for AUDs. (PsycINFO Database Record PMID- 29172603 TI - Trait emotion regulation strategies and diurnal cortisol profiles in healthy adults. AB - OBJECTIVE: Experimental studies have shown that 2 emotion regulation strategies suppression and reappraisal-are associated with differential profiles of physiological activation in response to a stress test. The present study aims to add to those findings by investigating whether individual differences in trait emotion regulation strategies are associated with diurnal cortisol patterns in a naturalistic context. METHOD: A sample of 46 men and women from the Midlife in the United States II (MIDUS II) study completed the Emotion Regulation Questionnaire (ERQ) and provided 4 salivary cortisol samples per day over 4 consecutive days. Trait reappraisal and suppression were tested as predictors of 3 cortisol parameters averaged across days: cortisol awakening response (CAR), diurnal cortisol slope (DCS), and area under the curve with respect to ground (AUCg). RESULTS: Higher scores on the suppression scale were associated with more physiological activation, as indicated by steeper CAR and flatter DCS. Suppression was not associated with AUCg, and reappraisal was not predictive of any cortisol parameter. CONCLUSIONS: Individual differences in suppression, but not reappraisal, were linked to greater cortisol activation in this naturalistic study. These preliminary results add to a growing body of findings that link suppression to adverse psychological and physiological profiles. (PsycINFO Database Record PMID- 29172602 TI - Personality and sleep quality: Evidence from four prospective studies. AB - OBJECTIVE: The present study examined the longitudinal association between personality traits and sleep quality in 4 samples of middle-aged and older adults. METHOD: Participants (N > 22,000) were adults aged 30 to 107 years old from the Wisconsin Longitudinal Study (WLS), the Midlife in the United States Study (MIDUS), the Health and Retirement Study (HRS), and the Midlife in Japan Study (MIDJA). Personality and sleep quality were assessed at baseline and again 4 to 10 years later. RESULTS: Scoring lower on neuroticism and higher on extraversion was associated with better sleep quality at baseline and over time, with effect sizes larger than those of demographic factors. Low conscientiousness was associated with a worsening of sleep quality over time. Openness and agreeableness were unrelated to sleep quality. Poor sleep quality at baseline was associated with steeper declines in extraversion, agreeableness, and conscientiousness and a smaller decrease in neuroticism over time. CONCLUSION: Replicable findings across samples support longitudinal associations between personality and sleep quality. This study identified specific personality traits that are associated with poor and worsening sleep quality, and substantiated previous findings that poor sleep quality is associated with detrimental personality trajectories. (PsycINFO Database Record PMID- 29172604 TI - Daily diary study of hope, stigma, and functioning in lung cancer patients. AB - OBJECTIVE: Given its lethality, associated stigma, and symptom burden, a lung cancer diagnosis poses a substantial challenge for patients. The goal of this study was to examine how daily hope, defined as goal-directed effort and planning to meet goals, and daily stigma were related to same- and next-day functioning in lung cancer patients receiving cancer treatment. METHODS: Fifty lung cancer patients (39 non-small-cell stages IIIa-IV; 11 limited and extensive small cell) completed a baseline questionnaire and 21 daily diaries (n = 1,042) assessing hope, stigma, physical symptoms, treatment factors, and functioning. Hypotheses were tested in same- and next-day models with multilevel modeling. RESULTS: Patients who reported more daily hope reported higher social and role functioning in same- and next-day models. On days that patients reported more hope than usual (compared with their own across-day average), they had higher social, role, and physical functioning; this effect did not carry into the next day. Treatment days were associated with lower social and role functioning when patients reported lower hope and associated with higher functioning when patients reported higher hope. Within-person hope was not predicted by disease symptoms. On days that patients reported more stigma than usual, they reported lower social and role functioning. CONCLUSIONS: Hope is associated with functioning in lung cancer patients, regardless of physical symptoms from disease and treatment. Hope and stigma may therefore be appropriate intervention targets to support daily social and role functioning during lung cancer treatment. (PsycINFO Database Record PMID- 29172605 TI - Treatment of depressive symptoms in patients with breast cancer: A randomized controlled trial comparing cognitive therapy and bright light therapy. AB - OBJECTIVE: This randomized controlled trial (RCT), conducted in patients with breast cancer, aimed to compare the effects of cognitive therapy (CT), bright light therapy (BLT), and a waiting-list control condition (WLC) on depressive symptoms. METHOD: Sixty-two women were randomly assigned to an 8-week CT (n = 25), BLT (n = 26), or WLC (n = 11). Participants completed the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D), the Beck Depression Inventory-II (BDI-II), and the Hamilton Depression Rating Scale (HDRS) at pre- and posttreatment (and postwaiting for WLC), as well as 3 and 6 months later. RESULTS: At posttreatment, CT patients had a significantly greater reduction of depressive symptoms than WLC on the HADS-D and the BDI-II. BLT patients had a greater reduction of depressive symptoms than WLC on the HADS-D only. After WLC participants were reassigned to CT or BLT, a superiority of CT over BLT was found on the BDI-II at posttreatment. Patients of both active conditions showed a good sustainment of treatment gains at follow-ups. CONCLUSIONS: Although replication with larger samples is needed, these results confirm the efficacy of CT for depression in the context of breast cancer and suggest that BLT could be of some utility when CT is not available or desired. (PsycINFO Database Record PMID- 29172606 TI - Ecological momentary assessment of self-attitudes in response to dietary lapses. AB - OBJECTIVE: To examine whether self-attitudes and self-efficacy after dietary lapses relate to lapse frequency or predict risk for lapsing again on the same day. METHOD: Adults with overweight/obesity (n = 91) completed ecological momentary assessment for 14 days at the start of a lifestyle modification program. At each survey, participants reported whether they had experienced a dietary lapse, and, if so, reported their self-attitudes (i.e., self-criticism, self-forgiveness, self-regard) and self-efficacy. The relationships between participants' typical (i.e., average level for each participant across lapses) self-attitudes/self-efficacy after lapsing and lapse frequency were examined using correlations. Generalized estimating equations examined whether participants' typical (average across lapses; between-person effect) self attitudes/self-efficacy or momentary (i.e., level of each variable at a particular lapse relative to one's typical level; within-person effect) self attitudes/self-efficacy predicted same-day lapse occurrence. RESULTS: Lower typical self-efficacy and more negative typical self-regard related to greater lapse frequency. Additionally, lower momentary self-criticism predicted greater likelihood of same-day lapse occurrence. There also was a quadratic relationship between typical self-regard and risk of same-day lapse occurrence, such that individuals with either more negative or more positive typical self-regard were more likely to lapse on the same day. CONCLUSION: Findings provide preliminary support for the relevance of self-attitudes and self-efficacy to lapses during early lifestyle modification. While greater typical self-efficacy and more positive typical self-regard are associated with fewer lapses, lower momentary self-criticism and very positive or negative typical self-regard may confer risk for same-day lapses. (PsycINFO Database Record PMID- 29172608 TI - Estimating and testing for differential treatment effects on outcomes when the outcome variances differ. AB - Researchers working in the context of randomized trials routinely estimate and test for treatment effects on the study outcomes. This article discusses the merits of assessing differential treatment effects across outcomes and proposes a multivariate approach using standardized outcomes for this purpose. This multivariate approach extends prior approaches to an arbitrary number of treatment groups and outcomes and does not require that the within-group covariance matrix have particular properties (e.g., sphericity). Theoretical analyses articulate the inferential basis for earlier recommendations for data standardization prior to analysis and demonstrate that inferential procedures (e.g., null hypothesis significance tests and confidence intervals) can exhibit poor operating characteristics when unstandardized outcome data are used for analysis and differential standardized treatment effects are the conceptual, intended target of inference. This article explores these and other issues (e.g., statistical power to detect and confidence intervals for differential standardized treatment effects) and demonstrates the proposed approach using data from a published experiment. The theoretical utility of differential treatment effect evidence is considered from a construct validity perspective for randomized trials. The proposed approach provides inferential procedures to evaluate theoretically motivated predictions for differential treatment effects on the outcomes; failure to support such predictions either calls the construct validity of the randomized trial into question or the underlying theory. The proposed approach also enables the detection of differences in treatment effects on the outcomes that are not theoretically expected; such results, especially if replicated, would motivate the need for theoretical refinements. (PsycINFO Database Record PMID- 29172607 TI - Social isolation, health literacy, and mortality risk: Findings from the English Longitudinal Study of Ageing. AB - OBJECTIVE: To investigate the relationships between social isolation, health literacy, and all-cause mortality, and the modifying effect of social isolation on the latter relationship. METHODS: Data were from 7731 adults aged >=50 years participating in Wave 2 (2004/2005) of the English Longitudinal Study of Ageing. Social isolation was defined according to marital/cohabiting status and contact with children, relatives, and friends, and participation in social organizations. Scores were split at the median to indicate social isolation (yes vs. no). Health literacy was assessed as comprehension of a medicine label and classified as "high" (>=75% correct) or "low" (<75% correct). The outcome was all-cause mortality up to February 2013. Cox proportional hazards models were adjusted for sociodemographic factors, health status, health behaviors, and cognitive function. RESULTS: Mortality rates were 30.3% versus 14.3% in the low versus high health literacy groups, and 23.5% versus 13.7% in the socially isolated versus nonisolated groups. Low health literacy (adj. HR = 1.22, 95% CI 1.02-1.45 vs. high) and social isolation (adj. HR = 1.28, 95% CI 1.10-1.50) were independently associated with increased mortality risk. The multiplicative interaction term for health literacy and social isolation was not statistically significant (p = .81). CONCLUSIONS: Low health literacy and high social isolation are risk factors for mortality. Social isolation does not modify the relationship between health literacy and mortality. Clinicians should be aware of the health risks faced by socially isolated adults and those with low health literacy. (PsycINFO Database Record PMID- 29172609 TI - Linear mixed-effects models and the analysis of nonindependent data: A unified framework to analyze categorical and continuous independent variables that vary within-subjects and/or within-items. AB - In this article we address a number of important issues that arise in the analysis of nonindependent data. Such data are common in studies in which predictors vary within "units" (e.g., within-subjects, within-classrooms). Most researchers analyze categorical within-unit predictors with repeated-measures ANOVAs, but continuous within-unit predictors with linear mixed-effects models (LMEMs). We show that both types of predictor variables can be analyzed within the LMEM framework. We discuss designs with multiple sources of nonindependence, for example, studies in which the same subjects rate the same set of items or in which students nested in classrooms provide multiple answers. We provide clear guidelines about the types of random effects that should be included in the analysis of such designs. We also present a number of corrective steps that researchers can take when convergence fails in LMEM models with too many parameters. We end with a brief discussion on the trade-off between power and generalizability in designs with "within-unit" predictors. (PsycINFO Database Record PMID- 29172610 TI - Multilevel autoregressive mediation models: Specification, estimation, and applications. AB - In the current study, extending from the cross-lagged panel models (CLPMs) in Cole and Maxwell (2003), we proposed the multilevel autoregressive mediation models (MAMMs) by allowing the coefficients to differ across individuals. In addition, Level-2 covariates can be included to explain the interindividual differences of mediation effects. Given the complexity of the proposed models, Bayesian estimation was used. Both a CLPM and an unconditional MAMM were fitted to daily diary data. The 2 models yielded different statistical conclusions regarding the average mediation effect. A simulation study was conducted to examine the estimation accuracy of Bayesian estimation for MAMMs and consequences of model mis-specifications. Factors considered included the sample size (N), number of time points (T), fixed indirect and direct effect sizes, and Level-2 variances and covariances. Results indicated that the fixed effect estimates for the indirect effect components (a and b) and the fixed effects of Level-2 covariates were accurate when N >= 50 and T >= 5. For estimating Level-2 variances and covariances, they were accurate provided a sufficiently large N and T (e.g., N >= 500 and T >= 50). Estimates of the average mediation effect were generally accurate when N >= 100 and T >= 10, or N >= 50 and T >= 20. Furthermore, we found that when Level-2 variances were zero, MAMMs yielded valid inferences about the fixed effects, whereas when random effects existed, CLPMs had low coverage rates for fixed effects. DIC can be used for model selection. Limitations and future directions were discussed. (PsycINFO Database Record PMID- 29172611 TI - Permutation randomization methods for testing measurement equivalence and detecting differential item functioning in multiple-group confirmatory factor analysis. AB - In multigroup factor analysis, different levels of measurement invariance are accepted as tenable when researchers observe a nonsignificant (Delta)chi2 test after imposing certain equality constraints across groups. Large samples yield high power to detect negligible misspecifications, so many researchers prefer alternative fit indices (AFIs). Fixed cutoffs have been proposed for evaluating the effect of invariance constraints on change in AFIs (e.g., Chen, 2007; Cheung & Rensvold, 2002; Meade, Johnson, & Braddy, 2008). We demonstrate that all of these cutoffs have inconsistent Type I error rates. As a solution, we propose replacing chi2 and fixed AFI cutoffs with permutation tests. Randomly permuting group assignment results in average between-groups differences of zero, so iterative permutation yields an empirical distribution of any fit measure under the null hypothesis of invariance across groups. Our simulations show that the permutation test of configural invariance controls Type I error rates better than chi2 or AFIs when the model contains parsimony error (i.e., negligible misspecification) but the factor structure is equivalent across groups (i.e., the null hypothesis is true). For testing metric and scalar invariance, Deltachi2 and permutation yield similar power and nominal Type I error rates, whereas DeltaAFIs yield inflated errors in smaller samples. Permuting the maximum modification index among equality constraints control familywise Type I error rates when testing multiple indicators for lack of invariance, but provide similar power as using a Bonferroni adjustment. An applied example and syntax for software are provided. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 29172612 TI - More stable estimation of the STARTS model: A Bayesian approach using Markov chain Monte Carlo techniques. AB - The STARTS (Stable Trait, AutoRegressive Trait, and State) model decomposes individual differences in psychological measurement across time into 3 sources of variation: a time-invariant stable component, a time-varying autoregressive component, and an occasion-specific state component. Previous simulation research and applications of the STARTS model have shown that serious estimation problems such as nonconvergence or inadmissible estimates (e.g., negative variances) frequently occur for STARTS model parameters. This article introduces a general approach to estimating the parameters of the STARTS model by employing Bayesian methods that use Markov Chain Monte Carlo (MCMC) techniques. With the specification of appropriate prior distributions, the Bayesian approach offers the advantage that the model estimates will be within the admissible range, and it should be possible to avoid estimation problems. Furthermore, we show how Bayesian methods can be used to stabilize STARTS model estimates by specifying weakly informative prior distributions for the model parameters. In a simulation study, the statistical properties (bias, root mean square error, coverage rate) of the parameter estimates obtained from the Bayesian approach are compared with those of the maximum-likelihood approach. A data example is presented to illustrate how the Bayesian approach can be used to estimate the STARTS model. Finally, further extensions of the STARTS model are discussed, and suggestions for applied research are made. (PsycINFO Database Record PMID- 29172613 TI - Prior sensitivity analysis in default Bayesian structural equation modeling. AB - Bayesian structural equation modeling (BSEM) has recently gained popularity because it enables researchers to fit complex models and solve some of the issues often encountered in classical maximum likelihood estimation, such as nonconvergence and inadmissible solutions. An important component of any Bayesian analysis is the prior distribution of the unknown model parameters. Often, researchers rely on default priors, which are constructed in an automatic fashion without requiring substantive prior information. However, the prior can have a serious influence on the estimation of the model parameters, which affects the mean squared error, bias, coverage rates, and quantiles of the estimates. In this article, we investigate the performance of three different default priors: noninformative improper priors, vague proper priors, and empirical Bayes priors with the latter being novel in the BSEM literature. Based on a simulation study, we find that these three default BSEM methods may perform very differently, especially with small samples. A careful prior sensitivity analysis is therefore needed when performing a default BSEM analysis. For this purpose, we provide a practical step-by-step guide for practitioners to conducting a prior sensitivity analysis in default BSEM. Our recommendations are illustrated using a well-known case study from the structural equation modeling literature, and all code for conducting the prior sensitivity analysis is available in the online supplemental materials. (PsycINFO Database Record PMID- 29172614 TI - A novel measure of effect size for mediation analysis. AB - Mediation analysis has become one of the most popular statistical methods in the social sciences. However, many currently available effect size measures for mediation have limitations that restrict their use to specific mediation models. In this article, we develop a measure of effect size that addresses these limitations. We show how modification of a currently existing effect size measure results in a novel effect size measure with many desirable properties. We also derive an expression for the bias of the sample estimator for the proposed effect size measure and propose an adjusted version of the estimator. We present a Monte Carlo simulation study conducted to examine the finite sampling properties of the adjusted and unadjusted estimators, which shows that the adjusted estimator is effective at recovering the true value it estimates. Finally, we demonstrate the use of the effect size measure with an empirical example. We provide freely available software so that researchers can immediately implement the methods we discuss. Our developments here extend the existing literature on effect sizes and mediation by developing a potentially useful method of communicating the magnitude of mediation. (PsycINFO Database Record PMID- 29172615 TI - Variable system: An alternative approach for the analysis of mediated moderation. AB - Mediated moderation (meMO) occurs when the moderation effect of the moderator (W) on the relationship between the independent variable (X) and the dependent variable (Y) is transmitted through a mediator (M). To examine this process empirically, 2 different model specifications (Type I meMO and Type II meMO) have been proposed in the literature. However, both specifications are found to be problematic, either conceptually or statistically. For example, it can be shown that each type of meMO model is statistically equivalent to a particular form of moderated mediation (moME), another process that examines the condition when the indirect effect from X to Y through M varies as a function of W. Consequently, it is difficult for one to differentiate these 2 processes mathematically. This study therefore has 2 objectives. First, we attempt to differentiate moME and meMO by proposing an alternative specification for meMO. Conceptually, this alternative specification is intuitively meaningful and interpretable, and, statistically, it offers meMO a unique representation that is no longer identical to its moME counterpart. Second, using structural equation modeling, we propose an integrated approach for the analysis of meMO as well as for other general types of conditional path models. VS, a computer software program that implements the proposed approach, has been developed to facilitate the analysis of conditional path models for applied researchers. Real examples are considered to illustrate how the proposed approach works in practice and to compare its performance against the traditional methods. (PsycINFO Database Record PMID- 29172616 TI - Culturally divergent consequences of receiving thanks in close relationships. AB - We investigated consequences of receiving thanks in close relationships across cultures. Chinese reported more negative feelings than Euro-Canadians after a close other said thanks to them. Likewise, Chinese participants predicted, more than Euro-Canadians did, that a close other would experience negative feelings after receiving thanks from them. No cultural difference was found when receiving thanks from an acquaintance. On the other hand, when not receiving thanks from close others after helping them, Euro-Canadians experienced more negative feelings than did Chinese. We showed that beliefs about saying thanks in close relationships accounted for cultural differences in emotions. Implications for intercultural communication, relationship maintenance, and directions for future research are discussed. (PsycINFO Database Record PMID- 29172617 TI - Preference for illusory contours: Beyond object symmetry, familiarity, and nameability. AB - It has previously been reported that individuals prefer figures from which they can extract shapes via illusory contours (Kanisza figures) over figures in which this is not possible. However, based on the past research in this area, it is not possible to distinguish the influence of illusory contour perception from other factors such as the symmetry, familiarity, prototypicality, and nameability of the perceived shape. Here, we investigate the influence of illusory contours in the absence of these confounding variables by measuring participants' aesthetic/liking ratings for symmetric Kanisza figures and for unfamiliar and asymmetric Kanisza figures. Results show that illusory contours do indeed influence preference above and beyond any effects of these other factors. (PsycINFO Database Record PMID- 29172618 TI - Visuospatial asymmetries and emotional valence influence mental time travel. AB - Spatial information is tightly intertwined with temporal and valence-based information. Namely, "past" is represented on the left, and "future" on the right, along a horizontal mental timeline. Similarly, right is associated with positive, whereas left is negative. We developed a novel task to examine the effects of emotional valence and temporal distance on mental representations of time. We compared positivity biases, where positive events are positioned closer to now, and right hemisphere emotion biases, where negative events are positioned to the left. When the entire life span was used, a positivity bias emerged; positive events were closer to now. When timeline length was reduced, positivity and right hemisphere emotion biases were consistent for past events. In contrast, positive and negative events were equidistant from now in the future condition, suggesting positivity and right hemisphere emotion biases opposed one another, leading events to be positioned at a similar distance. We then reversed the timeline by moving past to the right and future to the left. Positivity biases in the past condition were eliminated, and negative events were placed slightly closer to now in the future condition. We conclude that an underlying left-to right mental representation of time is necessary for positivity biases to emerge for past events; however, our mental representations of future events are inconsistent with positivity biases. These findings point to an important difference in the way in which we represent the past and the future on our mental timeline. (PsycINFO Database Record PMID- 29172619 TI - Differential effects of state and trait mindfulness on the late positive potential. AB - Mindfulness is an effective emotion regulation strategy, and its principles have formed the basis for several psychotherapies. Of interest is how a mindful perspective changes not only the subjective experience of emotion, but also neural activity involved in emotional processing. In a previous event-related potential (ERP) study, trait mindfulness was linked with reduced neural activity in response to affective stimuli, as measured by the late positive potential (LPP). Building on this result, we investigated how both state (i.e., task induced) and trait mindfulness would jointly affect the LPP in a large adult sample (N = 118). First, participants passively viewed affective images while ERP data were recorded. Participants were then instructed to adopt a mindful perspective and viewed a second, equivalent set of images. We hypothesized that the LPP would be reduced from the passive viewing to the mindful viewing condition. Contrary to our hypothesis, task-induced mindfulness increased LPP amplitude relative to passive viewing across all image types, suggesting that state mindfulness increases motivated attention to stimuli, regardless of affective valence and arousal. Trait mindfulness did not correlate with LPP amplitude in either the passive or mindful viewing conditions. As an unexpected finding, gender moderated the association between trait mindfulness and LPP amplitude to emotional images during mindful viewing. We propose that state and trait mindfulness impact emotional processing through different neural mechanisms and discuss implications for mindfulness as an emotion regulation strategy.

AB - Facial expressions of emotion contain important information that is perceived and used by observers to understand others' emotional state. While there has been considerable research into perceptions of facial musculature and emotion, less work has been conducted to understand perceptions of facial coloration and emotion. The current research examined emotion-color associations in the context of the face. Across 4 experiments, participants were asked to manipulate the color of face, or shape, stimuli along 2 color axes (i.e., red-green, yellow blue) for 6 target emotions (i.e., anger, disgust, fear, happiness, sadness, surprise). The results yielded a pattern that is consistent with physiological and psychological models of emotion. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 29172621 TI - Effects of oxytocin administration on receiving help. AB - Receiving help can be a "mixed blessing." Despite the many psychosocial benefits it can carry, it sometimes has negative psychological consequences, such as loss in self-esteem or enhanced guilt. It is, therefore, important to understand the factors that modify responses to receiving help from others. We explored the role of the hormone oxytocin (OT) on affective and social responses to receiving help, given the putative role of OT in social bonding and attunement. To this end, we manipulated whether help was received from a same-sex interaction partner (confederate) versus a control condition, crossed with a double-blind administration of intranasal OT (vs. placebo), and examined subjective and observer-rated participant responses to help. We observed significant interactions between OT and the help manipulation. In the placebo condition, receiving help from the interaction partner compared with the control condition had negative consequences, such that participants reported greater negative affect and came to view themselves and their interaction partners more negatively after interacting together on several tasks. What is important, however, is that OT administration buffered against these negative subjective responses to receiving help. Further, outside observers rated participants who received OT administration as expressing greater happiness and gratitude in response to help, relative to those who received placebo. In sum, in the context of receiving help from a stranger, oxytocin administration fostered more positive affective and social responses. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 29172622 TI - A multi-method investigation of the association between emotional clarity and empathy. AB - Higher emotional clarity, the extent to which people unambiguously identify, label, and describe their own emotions, is related to a host of positive intrapersonal factors but its relation to interpersonal factors is unexplored. We hypothesized that emotional clarity would be related to cognitive empathy (i.e., perceiving others' emotions) and to accurately understanding others' negative affect (NA), but not positive affect (PA), in the context of a stressful situation. After completing self-reports of trait emotional clarity and cognitive and affective empathy (i.e., one's emotional reaction to others), participants (N = 94 undergraduate students; i.e., perceivers) viewed a series of video clips of adults (i.e., targets) completing a stressful laboratory task in a previous research study. Before and after the stress task, targets reported their state NA and PA. While viewing the recordings, perceivers rated how they thought the targets were feeling at the corresponding time points. Correspondence between perceivers' and targets' affect ratings were used as indices of the outcome variable, performance-based cognitive empathy. As expected, self-reported emotional clarity was related to the self-reported cognitive, but not affective, empathy. Moreover, perceivers' emotional clarity was related to higher cognitive empathy for NA not PA after the stressful task. Our findings provide preliminary support for the importance of emotional clarity in the ability to accurately understand others' affective experiences, which has important interpersonal implications. (PsycINFO Database Record PMID- 29172623 TI - The structure of emotional experience and its relation to trait emotional awareness: A theoretical review. AB - Emotional experience (EE) and trait emotional awareness (tEA) have recently become topics of considerable experimental/theoretical interest within the cognitive and neural sciences. However, to date there has been limited empirical focus on how individual differences in the factors contributing to EE (a state based construct) might account for differences in tEA. To promote clear, well guided empirical research in this area, in this article we first offer a concise review of the primary factors contributing to EE. We then provide a theoretical investigation into how individual differences in these factors (i.e., differences in affective response generation, affective response representation, and conscious access) could mechanistically account for differences in tEA; we also discuss plausible origins of these individual differences in light of current empirical findings. Finally, we outline possible experiments that would support (or fail to support) the role of each factor in explaining differences in tEA-and how this added knowledge could shed light on the known link between low tEA and multiple emotion-related mental and systemic medical disorders.

AB - INTRODUCTION: Numerous studies have identified the importance of parenting behaviors to the well-being of children with chronic physical conditions. Synthesizing the findings of these studies has potential to identify which parenting behaviors are associated with specific aspects of child well-being. METHOD: We retrieved research reports addressing the relationship between parenting behaviors and well-being in children with chronic physical conditions, and categorized parenting behaviors based on Skinner, Johnson, and Snyder's (2005) core dimensions of parenting (warmth, rejection, structure, chaos, autonomy support, and coercion) Through meta-analysis, we examined relationships between parenting dimension and child well-being variables. RESULTS: Fifty-four reports from 47 unique studies met inclusion criteria. Parent warmth was associated with less child depression, better quality of life, better physical functioning, and fewer externalizing behavior problems. Parent rejection was associated with more child depression, internalizing/externalizing behavior problems, and poorer physical functioning. Parent structure was associated with better child physical functioning. Parent chaos was associated with poorer child physical functioning. Parent autonomy support was associated with better quality of life and fewer externalizing behavior problems. Parent coercion was associated with more child depression, poorer quality of life, poorer physical function, and more internalizing behavior problems. CONCLUSION: The results identify multiple, potentially modifiable parenting dimensions associated with well-being in children with a chronic condition, which could be targeted in developing family focused interventions. They also provide evidence that research using Skinner's core dimensions could lead to conceptualization and study of parenting behaviors in ways that would enable comparison of parenting in a variety of health and sociocultural contexts.

AB - INTRODUCTION: Spousal support is one of the strongest and most consistent predictors of Type 2 diabetes treatment adherence. However, the effects of both spouses' evaluations of dyadic coping on emotional distress and patients' physical health remain largely unknown. METHOD: Dyadic data from 117 married couples in which one member is diagnosed with Type 2 diabetes were evaluated in two separate models to explore the associations between (a) patients' and spouses' depression symptoms and patients' adherence to dietary and exercise regimens, and (b) patients' and spouses' acute stress levels and patients' adherence to dietary and exercise regimens. Finally, evaluative dyadic coping was included as a possible moderator between these associations. RESULTS: Results from an actor-partner interdependence model revealed significant actor effects of patients' depression symptoms on patients' adherence to dietary and exercise regimens. Spouses' evaluation of dyadic coping attenuated the direct paths between spouses' depression symptoms and patients' adherence to dietary regimens. No direct pathways were found from patients' or spouses' acute stress to patients' adherence to dietary and exercise regimens. However, spouses' evaluation of dyadic coping attenuated the direct paths between spouses' acute stress and patients' adherence to dietary regimens. DISCUSSION: Tapping into spouses' evaluations of dyadic coping has significant implications for patients' diabetes health outcomes (e.g., adherence to dietary and exercise treatment regimens). Findings from this study highlight the need for systemic interventions targeting both partners. (PsycINFO Database Record PMID- 29172626 TI - Attachment, household chaos, and children's health. AB - INTRODUCTION: Despite growing interest in the links between sociocontextual factors and children's behavioral functioning, few studies have investigated how such factors, in combination, relate to health outcomes or vary across mental and physical well-being. We evaluated the direct and interactive associations of parental attachment and household chaos with preschool-age children's mental and physical health. METHOD: Ninety-four parents completed questionnaires about their attachment styles, disorganization and confusion in the home, and their children's health functioning. RESULTS: Attachment avoidance and anxiety in parents predicted poorer mental health in children, particularly in highly chaotic homes. Moreover, parental attachment anxiety, but not avoidance, predicted poorer reported physical health in children and, in conjunction with chaotic homes, more hospitalizations. DISCUSSION: The results help illuminate how multiple domains in children's immediate environment jointly influence their physical and mental health and how these influences may vary across domains of functioning. Findings have implications for targeting interventions to have impact across facets of children's health. (PsycINFO Database Record PMID- 29172627 TI - Pediatric primary care psychologists' reported level of integration, billing practices, and reimbursement frequency. AB - INTRODUCTION: Integration of psychological services into pediatric primary care is increasingly common, but models of integration vary with regard to their level of coordination, colocation, and integration. High-integration models may provide some distinct advantages, such as preventative care and brief consultation for subclinical behavior concerns; however, psychologists face barriers to seeking reimbursement for these services. Alternatives to traditional psychotherapy and psychological testing codes, specifically Health & Behavior (H&B) codes, have been proposed as 1 method for supporting integrated care. The aim of this study was to investigate the relationships between psychologists' reported billing practices, reimbursement rates, and model of integration in pediatric primary care. METHOD: As part of a larger survey study, 55 psychologists working in pediatric primary care reported on characteristics of their practice's model of integration, billing practices, and frequency of reimbursement for consultative services. RESULTS: Compared with those who categorized their integrated care model as colocated, psychologists who endorsed working in integrated models reported a significantly higher usage of H&B codes and more frequent reimbursement for consultations. Overall, use of H&B codes was associated with higher reported levels of coordination and integration. DISCUSSION: Survey results showed a clear pattern of higher integration being associated with greater utilization of H&B codes and better reimbursement for consultation activities. These results underscore the importance of establishing and maintaining billing and reimbursement systems that adequately support integrated care. (PsycINFO Database Record PMID- 29172628 TI - Adolescent and parent perspectives on medical decision-making for chronic illness. AB - INTRODUCTION: The objective of the study was to assess correlates of adolescent and parent perceptions of their involvement in medical decision-making (MDM). METHOD: Study participants included 28 pairs of pediatric patients with chronic rheumatologic illnesses and their parents presenting to an outpatient rheumatology clinic. Participants completed measures assessing perceptions of MDM involvement, health consciousness, and decisional conflict. RESULTS: Adolescent health consciousness correlated positively with parent health consciousness and adolescent-valuing involvement. There was a significant positive correlation between adolescents-valuing involvement in medical decisions and perception of actual involvement. Adolescents who perceived themselves as more involved in their care reported less decisional conflict. Parents who wanted to participate in MDM reported greater actual involvement. DISCUSSION: Adolescents who value participation in MDM reported higher levels of actual participation, suggesting their preferences may be considered by providers. Greater engagement in MDM was related to lower decisional conflict for adolescents, suggesting that including adolescents in the MDM process does not necessarily result in confusion or distress. (PsycINFO Database Record PMID- 29172630 TI - Lexical tone is perceived relative to locally surrounding context, vowel quality to preceding context. AB - Important speech cues such as lexical tone and vowel quality are perceptually contrasted to the distribution of those same cues in surrounding contexts. However, it is unclear whether preceding and following contexts have similar influences, and to what extent those influences are modulated by the auditory history of previous trials. To investigate this, Cantonese participants labeled sounds from (a) a tone continuum (mid- to high-level), presented with a context that had raised or lowered fundamental frequency (F0) values and (b) a vowel quality continuum (/u/ to /o/), where the context had raised or lowered first formant (F1) values. Contexts with high or low F0/F1 were presented in separate blocks or intermixed in 1 block. Contexts were presented following (Experiment 1) or preceding the target continuum (Experiment 2). Contrastive effects were found for both tone and vowel quality (e.g., decreased F0 values in contexts lead to more high tone target judgments and vice versa). Importantly, however, lexical tone was only influenced by F0 in immediately preceding and following contexts. Vowel quality was only influenced by the F1 in preceding contexts, but this extended to contexts from preceding trials. Contextual influences on tone and vowel quality are qualitatively different, which has important implications for understanding the mechanism of context effects in speech perception. (PsycINFO Database Record PMID- 29172629 TI - Physician perceptions of children's coping with asthma are associated with children's psychosocial and disease functioning. AB - INTRODUCTION: Low-income, ethnic minority children disproportionately face poor asthma control, and poorly controlled asthma is related to psychosocial difficulties. This study assessed physician reports of coping in child patients and examined associations between physician reports of child coping and parent and child reports of children's coping, psychosocial, and asthma outcomes (asthma related stress, emotional and behavioral problems, asthma control, and school missed due to asthma). METHOD: Physicians reported on coping in their patients (N = 67) ages 5-17 with asthma. Parents reported on child coping, asthma-related stress, emotional and behavioral problems, asthma control, and school missed due to asthma. Children ages 9-17 provided self-reports. RESULTS: Physicians' reports of primary control coping (e.g., problem solving) and secondary control coping (e.g., cognitive restructuring) were not associated with parent ratings of corresponding coping strategies, but physician reports of disengagement coping (e.g., avoidance) were correlated with parent reports of disengagement and secondary control coping. Physician perceptions of higher child primary control, and lower disengagement, were correlated with less parent-reported stress, better asthma control, and for primary control, fewer partial days of school missed. Physician reports were not correlated with child reports of coping, but physician reports of disengagement were correlated with child-reported conduct problems. DISCUSSION: Findings suggest that physician reports of child coping provide independent information from parent and child reports of coping, and could be leveraged to identify and intervene with patients who are at elevated risk for poor outcomes. (PsycINFO Database Record PMID- 29172631 TI - Different structural alterations in individual conduit arteries of SHRs compared to Wistar rats from the prehypertensive period to late adulthood. AB - Structural changes of thoracic aorta (TA), carotid (CA) and iliac artery (IA) were assessed in Wistar and spontaneously hypertensive rats (SHR) aged 3, 17, and 52 weeks. Systolic blood pressure (sBP) was measured by plethysmography weekly. After perfusion fixation the arteries were processed for electron microscopy. The wall thickness (WT), cross-sectional area (CSA), inner diameter (ID), and WT/ID in all arteries and volume densities of endothelial cells (ECs), muscle cells (SMCs), and extracellular matrix (ECM) in TA were measured and their CSAs were calculated. In 3-week-old SHR compared to Wistar rats, sBP did not differ; in the TA, all parameters (WT, CSA, ID, WT/ID, CSA of SMCs, CSA of ECs, and CSA of ECM) were decreased; in CA, WT and CSA did not differ, ID was decreased, and WT/ID was increased; in IA, WT, CSA, and ID were increased. In 17- and 52-week-old SHRs, sBP and all parameters in all arteries were increased, only ID in IE in 52-week old SHRs and CSA of ECs in the TA in 17-week-old SHRs did not change. Disproportionality between BP increase and structural alterations during ontogeny in SHR could reflect the flexibility of the arterial tree to the different needs of supplied areas. PMID- 29172632 TI - Dual- and Polytobacco/Nicotine Product Use Trends in a National Sample of High School Students. AB - PURPOSE: The study purpose was to examine changes in patterns of ever and current dual- and polyproduct use over time and to examine demographic and modifiable risk factors including tobacco smoke exposure (TSE). DESIGN: A secondary analysis of the 2013 to 2015 National Youth Tobacco Survey data. SETTING: Nationwide high schools were selected. SUBJECTS: A total of 31 022 high school students. MEASURES: Ever and current (past 30 days) tobacco/nicotine product use, home tobacco/nicotine product use, TSE and e-cigarette vapor exposure, and demographic characteristics were measured. ANALYSIS: Multivariable logistic regression and multinomial logistic regression models. RESULTS: Of the students, 9.4% were ever dual users and 18.6% were ever poly users. Rates of ever/current use of e cigarettes and hookah increased from 2013 to 2015 (all Ps < .001). In 2015, participants were 4.8 times (95% confidence interval [CI], 4.5-5.2) and 4.0 times (95% CI, 3.5-4.4) more likely to report ever/current e-cigarette use and 1.61 times (95% CI, 1.5-1.7) and 1.48 times (95% CI, 1.3-1.7) more likely to report ever/current hookah use. Participants reporting TSE were 15.4 times (95% CI, 11.5 21.0) more likely to report current poly use, and those with e-cigarette exposure were 10.4 times (95% CI, 7.8-13.8) more likely to report current poly use. CONCLUSION: From 2013 to 2015, rates of ever and current use of e-cigarettes and hookah increased. Tobacco smoke and e-cigarette exposure were associated with higher rates of dual and poly use. Prevention efforts targeting these products are needed. PMID- 29172633 TI - Understanding the impact of adaptations to a parent-mediated intervention on parents' ratings of perceived barriers, program attributes, and intent to use. AB - Within the autism spectrum disorder field, rates of attrition in parent-mediated interventions have highlighted the need to engage families around improving the delivery of these services. The primary goal of this study was to approximate the impact of adaptations to an evidence-based, parent-mediated intervention, Project ImPACT (Improving Parents as Communication Teachers), that had been made in collaboration with families in a Medicaid system. A total of 103 parents of a child with autism spectrum disorder were randomized to watch a presentation of either the original or adapted Project ImPACT program. After watching the presentation, participants rated (1) demographic information, (2) perceived structural barriers, (3) Project ImPACT attributes, and (4) intent to use the program. Results from hierarchical linear regression models demonstrated that program type alone predicted parents' ratings of perceived structural barriers. Additionally, both program type and the interaction of program type and annual household income were unique predictors of parents' ratings of program attributes and intent to use. Qualitatively, although many parents reflected positively on both Project ImPACT programs, parents who viewed the adapted program appeared more likely to report positive program attributes. Results suggest the importance of engaging families in improving the fit of parent-mediated interventions for use within a variety of community settings.

AB - BACKGROUND: Although surgical shoulder stabilization by coracoid transfer is effective for collision athletes and has a low reinjury rate, no reports have described the midterm results of this procedure in specific patient cohorts of sufficient number or provided subjective assessments of these patients. PURPOSE: To evaluate midterm results after treatment of shoulder instability with the Bristow procedure in a large cohort of rugby players. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: This study included 176 shoulders of 152 competitive rugby players who underwent shoulder stabilization surgery (Bristow procedure with Bankart repair) with a mean follow-up of 4 years (minimum of 2 years) in our institute. The primary outcome measure was the difference in the presurgical and postsurgical functional Rowe score and Western Ontario Shoulder Instability index (WOSI) score and factors affecting these scores. Complication rates and associated factors were also investigated. RESULTS: In total, 176 shoulders of 152 patients underwent the Bristow procedure with Bankart repair, and 93.2% of the players returned to their preinjury competition level at a mean of 6.3 months postoperatively. All Rowe and WOSI scores were significantly improved after surgery. The numbers of shoulders with functional failure as indicated by the Rowe score, WOSI score, and inability to return to the previous level of play were 28 (15.9%), 54 (30.7%), and 12 (6.8%), respectively. Multiple logistic regression analyses demonstrated that reinjury after surgery (odds ratio [OR] = 35.1) and the number of shoulder dislocations (OR = 11.2-11.4) negatively affected the competition level after return to play, while reinjury (OR = 11.1 17.8), the number of shoulder subluxations (OR = 1.1-2.9), injury in the dominant shoulder (OR = 1.2-2.2), and large bone defects (OR = 1.1-11.5) negatively affected functional scores. Reinjury after shoulder stabilization occurred in 6 of 176 shoulders (3.4%). Multiple logistic regression analysis demonstrated that reinjury after surgery occurred more frequently in players at lower versus higher grade levels of competition (OR = 21.0). Although differences were not significant, a trend was noted toward higher postoperative reinjury rates in forward players, those in the upper categories (professional and college), and those with injury in the nondominant shoulder. CONCLUSION: The Bristow procedure provides good midterm outcomes for competitive collision athletes, while postsurgical reinjury, the number of preoperative dislocations and subluxations, and large bone defects negatively affect postsurgical shoulder function. This information may be useful for treatment of shoulder dislocations in collision athletes. PMID- 29172636 TI - Patient and Provider Perspectives on a Mind-Body Program for Grieving Older Adults. AB - BACKGROUND: Spousal bereavement in older age is a major stressor associated with an increase in both mental and physical problems. The Stress Management and Resiliency Training: Relaxation Response Resiliency Program (SMART-3RP) is an 8 week multimodal mind-body program that targets stress and has been found efficacious in decreasing the mental and physical manifestations of stress in varied populations. This qualitative study sought to investigate the relevance, credibility, and feasibility of the SMART-3RP in the community. METHODS: Focus groups were conducted among both older widowed adults and providers who support them in the community (eg, chaplains, hospice bereavement coordinators). Transcripts were coded independently by coders trained in qualitative research. Codebooks were created based on both general themes and detailed subthemes present in the transcripts. RESULTS: Findings from 4 focus groups revealed a general convergence between the needs of recently widowed older adults reported by widow(er)s and community providers alike and needs identified in the literature. Several components of the SMART-3RP target many of these needs (eg, social support, stress awareness, coping skills), making both community providers and widow(er)s report that the SMART-3RP is logical (89%) and would be helpful (100%) and successful in reducing symptoms (78%). Additionally, all widow(er)s reported a willingness to participate (100%). Feedback from the focus groups was used to adapt the SMART-3RP to improve its relevance to grief-related stress. CONCLUSIONS: Our findings suggest that the SMART-3RP may be helpful in decreasing somatic and psychological distress in older adults who have lost a spouse. PMID- 29172637 TI - Discrepancies Between the Supports Needed for Discharge of Patients With Terminal Cancer to Family Caregivers and What Supports Were Actually Provided in Japan: Assessment of Palliative Care Unit Nurses. AB - OBJECTIVES: Even if patients with terminal cancer hope to spend the rest of their lives at home, they are often unable to leave the hospital early due to their family caregivers' anxiety. This study aimed to investigate in Japan the discrepancies between the supports needed by and actually provided by palliative care unit nurses (PCUNs) to the family caregivers for discharge of patients with terminal cancer. METHODS: In this cross-sectional study, self-administered questionnaires including 6-point Likert-type scales assessing the reasons for difficulties in transition to home-based care were distributed to 1227 PCUNs. Using paired t tests, the differences between the scores on perceived importance and actual supports to family caregivers were examined. The supports actually provided were classified by factor analysis. The relationships between the PCUNs' characteristics and mean scores on the supports in each category were examined using multiple regression analysis. RESULTS: A total of 1023 (83.4%) completed questionnaires were returned. Scores on the actually provided supports for discharge to family caregivers were consistently and significantly lower than the corresponding scores on perceived importance for all 57 items ( P < .001). Factor analysis revealed that the supports actually provided to the family caregivers had a 4-factor structure. Multiple regression analyses revealed that gaining experience in palliative care, receiving necessary training, cooperating with palliative care staff, and cooperating with local service providers were significantly associated with higher levels of actual supply of supports to family caregivers. CONCLUSION: Our findings suggest that PCUNs need to be encouraged to provide further support to family caregivers for the discharge of patients with terminal cancer. PMID- 29172638 TI - The Survey of Favorite Interests and Activities: Assessing and understanding restricted interests in children with autism spectrum disorder. AB - Restricted interests are an established diagnostic symptom of autism spectrum disorder. While there is considerable evidence that these interests have maladaptive consequences, they also provide a range of benefits. This article introduces a new instrument, the Survey of Favorite Interests and Activities, and uses it to examine the nature of restricted interests in autism spectrum disorder. Respondents report substantial benefits of restricted interests as well as areas of difficulty. The Survey of Favorite Interests and Activities assesses Social Flexibility, Perseveration, Respondent Discomfort, Adaptive Coping, and Atypicality. All scales have Cronbach's alpha > 0.70. Age and socioeconomic status have little effect on Survey of Favorite Interests and Activities scales; nor does gender with the exception of interest Atypicality. The expected pattern of correlations with existing scales was found. Research and clinical implications are discussed. PMID- 29172640 TI - The art is in the delivery. PMID- 29172641 TI - Identification of Diagnostic Criteria for Chronic Hypersensitivity Pneumonitis: An International Modified Delphi Survey. AB - RATIONALE: Current diagnosis of chronic hypersensitivity pneumonitis (cHP) involves considering a combination of clinical, radiological, and pathological information in multidisciplinary team discussions. However, this approach is highly variable with poor agreement between centers. OBJECTIVES: We aimed to identify diagnostic criteria for cHP that reach consensus among international experts. METHODS: A 3-round modified Delphi survey was conducted between April and August 2017. Forty-five experts in interstitial lung disease from 14 countries participated in the online survey. Diagnostic items included in round 1 were generated using expert interviews and literature review. During rounds 1 and 2, experts rated the importance of each diagnostic item on a 5-point Likert scale. The a priori threshold of consensus was >= 75% of experts rating a diagnostic item as very important or important. In the third round, experts graded the items that met consensus as important and provided their level of diagnostic confidence for a series of clinical scenarios. MEASUREMENTS AND MAIN RESULTS: Consensus was achieved on 18 of the 40 diagnostic items. Among these, experts gave the highest level of importance to the identification of a causative antigen, time relation between exposure and disease, mosaic attenuation on chest imaging, and poorly formed non-necrotizing granulomas on pathology. In clinical scenarios, the diagnostic confidence of experts in cHP was heightened by the presence of these diagnostic items. CONCLUSION: This consensus-based approach for the diagnosis of cHP represents a first step towards the development of international guidelines for the diagnosis of cHP. PMID- 29172642 TI - Comparison of automated volumetry of the hippocampus using NeuroQuant(r) and visual assessment of the medial temporal lobe in Alzheimer's disease. AB - Background Different clinically feasible methods for evaluation of medial temporal lobe atrophy exists and are useful in diagnostic work-up of Alzheimer's disease (AD). Purpose To compare the diagnostic properties of two clinically available magnetic resonance imaging (MRI)-based methods-an automated volumetric software, NeuroQuant(r) (NQ) (evaluation of hippocampus volume) and the Scheltens scale (visual evaluation of medial temporal lobe atrophy [MTA])-in patients with AD dementia, and subjective and mild cognitive impairment (non-dementia). Material and Methods MRIs from 56 patients (31 AD, 25 non-dementia) were assessed with both methods. Correlations between the methods were calculated and receiver operating curve (ROC) analyses that yield area under the curve (AUC) statistics were conducted. Results High correlations were found between the two MRI assessments for the total hippocampal volume measured with NQ and mean MTA score (-0.753, P < 0.001), for the right (-0.767, P < 0.001), and for the left (-0.675, P < 0.001) sides. The NQ total measure yielded somewhat higher AUC (0.88, "good") compared to the MTA mean measure (0.80, "good") in the comparison of patients with AD and non-dementia, but the accuracy was in favor of the MTA scale. Conclusion The two methods correlated highly and both methods reached equally "good" power. PMID- 29172643 TI - Prevalence and Characteristics of Interpersonal Violence in People Dying From Suicide in Victoria, Australia. AB - Victims of interpersonal violence are known to be at increased risk of suicidal ideation and attempts; however, few data exist on the impact that violence has on the risk of death from suicide. This study examined 2153 suicides (1636 males and 517 females) occurring between 2009 and 2012. Information was sourced from the Coroners Court of Victoria's Suicide Register, a detailed database containing information on all Victorian suicides. Forty-two percent of women who died from suicide had a history of exposure to interpersonal violence, with 23% having been a victim of physical violence, 18% suffering psychological violence, and 16% experiencing sexual abuse. A large number of men who died from suicide had also been exposed to interpersonal violence, many of whom had perpetrated violence within the 6 weeks prior to their death. Targeted prevention, particularly removing barriers for men to seek help early after perpetrating violence is likely to have benefits in preventing suicide in both men and women. PMID- 29172644 TI - Combined thoracic and hepatobiliary surgery for iatrogenic bronchobiliary fistula. AB - Bronchobiliary fistula is a rare pathology mainly caused by hepatic tumors, bile duct obstruction, or hepatic hydatid disease. A 70-year-old man developed a bronchobiliary fistula after biliary stenting. After failure of conservative treatment including endoscopic retrograde biliary drainage, he underwent a combined operation with a two-level approach. Both a thoracotomy and laparotomy were performed, allowing pulmonary resection, diaphragmatic repair, and bile duct reconstruction during the same operation. Postoperative follow-up at one year showed optimal healing of the fistula. PMID- 29172645 TI - A Homogeneous Cell-Based Halide-Sensitive Yellow Fluorescence Protein Assay to Identify Modulators of the Cystic Fibrosis Transmembrane Conductance Regulator Ion Channel. AB - Cystic fibrosis (CF), an inherited genetic disease, is caused by mutation of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene, which encodes an ion channel involved in hydration maintenance by anion homeostasis. Ninety percent of CF patients possess one or more copies of the F508del CFTR mutation. This mutation disrupts trafficking of the protein to the plasma membrane and diminishes function of mature CFTR. Identifying small molecule modulators of mutant CFTR activity or biosynthesis may yield new tools for discovering novel CF treatments. One strategy utilizes a 384-well, cell-based fluorescence-quenching assay, which requires extensive wash steps, but reports sensitive changes in fluorescence-quenching kinetic rates. In this study, we describe the methods of adapting the protocol to a homogeneous, miniaturized 1,536-well format and further optimization of this functional F508del CFTR assay. The assay utilizes a cystic fibrosis bronchial epithelial (CFBE41o-) cell line, which was engineered to report CFTR-mediated intracellular flux of iodide by a halide-sensitive yellow fluorescence protein (YFP) reporter. We also describe the limitations of quench rate analysis and the subsequent incorporation of a novel, kinetic data analysis modality to quickly and efficiently find active CFTR modulators. This format yields a Z' value interval of 0.61 +/- 0.05. As further evidence of high throughput screen suitability, we subsequently completed a screening campaign of >645,000 compounds, identifying 2,811 initial hits. After completing secondary and tertiary follow-up assays, we identified 187 potential CFTR modulators, which EC50's < 5 MUM. Thus, the assay has integrated the advantages of a phenotypic screen with high-throughput scalability to discover new small-molecule CFTR modulators. PMID- 29172646 TI - 3,7-Dideazaneplanocin: Synthesis and antiviral analysis. AB - Objective To synthesize 3,7-dideazaneplanocin and evaluate its antiviral potential. Methods The target 3,7-dideazaneplanocin has been prepared in five steps from a readily available cyclopentenol. A thorough in vitro antiviral analysis was conducted versus both DNA and RNA viruses. Results A rational synthesis of 3,7-dideazaneplanocin was conceived and successfully pursued in such a way that it can be adapted to various analogs of 3,7-dideazaneplanocin. Using standard antiviral assays, no activity for 3,7-dideazaneplanocn was found. Conclusion Two structural features are necessary for adenine-based carbocyclic nucleosides (like neplanocin) for potential antiviral properties: (i) inhibition of S-adenosylhomocysteine hydrolase and/or (ii) C-5' activation via the mono nucleotide. These two requisite adenine structural features to fit these criteria are not present in in the target 3,7-dideazaneplanocin: (i) an N-7 is necessary for inhibition of the hydrolase and the N-3 is claimed to be essential for phosphorylation at C-5'. Thus, it is not surprising that 3,7-dideazaneplaoncin lacked antiviral properties. PMID- 29172647 TI - Clinical Utility of the Sport Concussion Assessment Tool 3 (SCAT3) Tandem-Gait Test in High School Athletes. AB - CONTEXT: Dynamic balance during functional movement may provide important clinical information after concussion. The Sport Concussion Assessment Tool, version 3 (SCAT3), includes a timed tandem-gait test (heel-to-toe walking) administered with a pass-fail scoring system. Minimal evidence supports inclusion of the tandem-gait test in the SCAT3, especially in high school athletes. OBJECTIVE: To determine (1) the percentage of healthy high school athletes who passed (best trial <=14 seconds) the tandem-gait test at baseline, (2) the association between sex and test performance (pass versus fail), and (3) the relationships among sex, age, height, and tandem-gait test score. DESIGN: Cross sectional study. SETTING: High school sports medicine center. PATIENTS OR OTHER PARTICIPANTS: Two hundred athletes from 4 high schools (age = 15.8 +/- 1.2 years, height = 170.3 +/- 10.3 cm, weight = 64.8 +/- 14.5 kg). MAIN OUTCOME MEASURE(S): Healthy participants completed 4 trials of the SCAT3 tandem-gait test and a demographic questionnaire. Outcome measures were passing rate at baseline on the tandem-gait test and tandem-gait test score (time). RESULTS: Overall, 24.5% (49/200) of participants passed the test. Sex and performance were associated (chi2 = 15.15, P < .001), with a passing rate of 38.6% (32/83) for males and 14.5% (17/117) for females. The regression model including predictor variables of sex and height, with the outcome variable of tandem-gait test score and time, was significant ( R2 = 0.20, P < .01). CONCLUSIONS: Our findings suggest that the tandem-gait test had a high false-positive rate in high school athletes. Given that more than 75% of healthy participants failed the tandem-gait test, the 14-second cutoff appears to have limited clinical utility in the adolescent population. Functional movement deficits after concussion need to be accounted for, but the 14-second cutoff for the SCAT3 tandem-gait test does not appear to be an ideal way to assess these deficits in high school athletes.

AB - : Reference/Citation: Donnell-Fink LA, Klara K, Collins JE, et al. Effectiveness of knee injury and anterior cruciate ligament tear prevention programs: a meta analysis. PLoS One. 2015;10(12)e0144063. CLINICAL QUESTION: Is neuromuscular and proprioceptive training effective in preventing knee and anterior cruciate ligament (ACL) injuries? DATA SOURCES: The authors searched CINAHL, Cochrane Central Register of Controlled Trials, MEDLINE/EMBASE, PubMed, and Web of Science databases from 1996 through December 2014 and limited the results to peer reviewed manuscripts published in English. Search terms for all databases were knee injury OR knee injuries; OR anterior cruciate ligament injury OR anterior cruciate ligament injuries; OR ACL injury OR ACL injuries; OR lower limb injury OR lower limb injuries AND prevention. STUDY SELECTION: Inclusion criteria were (1) English language, (2) published from 1996 through 2014, (3) the intervention used neuromuscular or proprioceptive training to prevent knee or ACL injuries, (4) human participants, (5) the incidence of knee or ACL injury was provided. DATA EXTRACTION: For the articles that met the inclusion criteria, 2 authors worked independently using the Jadad scale to extract the first author, year of publication, title, sport type, participant sex, participant age, country in which the study was conducted, number of participants in the control and intervention groups, intervention characteristics or components, and knee or ACL injury outcome. MAIN RESULTS: A total of 24 studies with 1093 participants were included in this review. Intervention efficacy was determined from weighted incidence rate ratios. After the intervention of neuromuscular and proprioceptive training exercises, the incidence ratio (frequency of a disease or injury occurrence in a population over a specific time frame) was calculated at 0.731 (95% confidence interval = 0.614, 0.871) for knee injury and at 0.493 (95% confidence interval = 0.285, 0.854) for ACL injury. This indicated a link between neuromuscular and proprioceptive training programs and injury reduction. No significant correlation was present between more components added to training and a greater decrease in injury to either the knee or ACL. CONCLUSIONS: Neuromuscular and proprioceptive training appeared to decrease the incidence of injury to the knee and specifically the ACL. However, no evidence suggested that a specific group of exercises was better than others. PMID- 29172649 TI - Examining the Environmental Effects of Athletic Training: Perceptions of Waste and the Use of Green Techniques. AB - CONTEXT: Environmental sustainability is a critical concern in health care. Similar to other professions, the practice of athletic training necessitates the use of a large quantity of natural and manufactured resources. OBJECTIVE: To examine the perceptions of the waste produced by the practice of athletic training and the green practices currently used by athletic trainers (ATs) to combat this waste. DESIGN: Mixed-methods study. SETTING: Field setting. PATIENTS OR OTHER PARTICIPANTS: A total of 442 ATs completed the study. Sixteen individuals participated in the qualitative portion. MAIN OUTCOME MEASURE(S): Data from sections 2 and 3 of the Athletic Training Environmental Impact Survey were analyzed. Focus groups and individual interviews were used to determine participants' views of waste and the efforts used to combat waste. Descriptive statistics were used to examine types of waste. Independent t tests, chi2 tests, and 1-way analyses of variance were calculated to identify any differences between the knowledge and use of green techniques. Interviews and focus groups were transcribed verbatim and analyzed inductively. RESULTS: Participants reported moderate knowledge of green techniques (3.18 +/- 0.53 on a 5-point Likert scale). Fifty-eight percent (n = 260) of survey participants perceived that a substantial amount of waste was produced by the practice of athletic training. Ninety-two percent (n = 408) admitted they thought about the waste produced in their daily practice. The types of waste reported most frequently were plastics (n = 111, 29%), water (n = 88, 23%), and paper for administrative use (n = 81, 21%). Fifty-two percent (n = 234) agreed this waste directly affected the environment. The qualitative aspect of the study reinforced recognition of the large amount of waste produced by the practice of athletic training. Types of conservation practices used by ATs were also explored. CONCLUSIONS: Participants reported concern regarding the waste produced by athletic training. The amount of waste varies depending on practice size and setting. Future researchers should use direct measures to determine the amount of waste created by the practice of athletic training.

AB - CONTEXT: Environmental sustainability efforts are becoming a critical concern in health care. However, little is known regarding how athletic trainers feel about the environment or what can be done to reduce the environmental impact of the practice of athletic training. OBJECTIVE: To examine athletic trainers' attitudes toward and perceptions of factors related to environmental sustainability. DESIGN: Sequential, mixed methods using a survey, focus groups, and personal interviews. SETTING: Field study. PATIENTS OR OTHER PARTICIPANTS: Four hundred forty-two individuals completed the survey. Sixteen participated in the qualitative portion. MAIN OUTCOME MEASURE(S): Quantitative results from the Athletic Training Environmental Impact Survey included data from a 5-point Likert scale (1 = lowest rating and 5 = highest rating). Descriptive statistics and 1 way analyses of variance were used to describe perceptions and determine differences in mean opinion, National Athletic Trainers' Association district, and use of green techniques. Qualitative data were transcribed verbatim and analyzed inductively. RESULTS: The mean score for opinion of the environment was 3.30 +/- 0.52. A difference was found between opinion and National Athletic Trainers' Association district ( F9, 429 = 2.43, P = .01). A Bonferroni post hoc analysis identified this difference ( P = .03) between members of District 2 (Delaware, New Jersey, New York, Pennsylvania) and District 9 (Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, Tennessee). An inductive analysis resulted in 3 emergent themes: (1) barriers to using green techniques, (2) motivators for using green techniques, and (3) solutions to overcoming the barriers. The information gleaned from participants in the qualitative portion of the study can be useful for clinicians wishing to implement basic conservation efforts in their practice settings and may guide future sustainability projects. CONCLUSIONS: Overall, participants reported a positive opinion of environmental sustainability topics related to athletic training. However, many barriers to practicing green techniques were identified.

AB - We investigated the relationship of ischemia-modified albumin (IMA) and high sensitivity C-reactive protein (hsCRP) levels with direct (endocan) and indirect (carotid intima-media thickness [cIMT] and 24 hours urine protein excretion) endothelial dysfunction indicators in type 2 diabetes mellitus (T2DM). Patients with T2DM (n = 88) and 88 healthy individuals were included in the study. The median endocan (475.15 vs 216.37 pg/mL; P < .001, respectively) and hsCRP (10.74 vs 3.11 mg/L; P < .001, respectively) and the mean IMA (0.64 +/- 0.12 vs 0.51 +/- 0.12 absorbance units; P < .001, respectively) levels were higher in participants with endothelial dysfunction compared to those without endothelial dysfunction in T2DM. The 24-hour urine protein excretion and cIMT levels had a positive correlation with hsCRP ( r = .357; P = .001 and r = .592; P < .001, respectively), IMA ( r = .519; P < .001 and r = .495; P < .001, respectively) and endocan ( r = .347; P = .001 and r = .583; P < .001, respectively) levels in the T2DM group. Stepwise multivariable logistic regression analysis, which included laboratory findings found to be associated with endothelial dysfunction, showed that endocan (odds ratio [OR] = 1.456; P = .004), hsCRP (OR = 1.298; P = .008), and IMA (OR = 2.270, P = .003) were independent risk factors. It was found that none of these markers were superior in terms of diagnostic discrimination for endothelial dysfunction. Endocan, IMA, and hsCRP levels were found to be associated with endothelial dysfunction in patients with T2DM.

AB - The association of coronary artery disease (CAD) severity with increased C reactive protein (CRP) and decreased albumin levels has been reported. However, to our knowledge, no study has investigated the usefulness of the CRP to albumin ratio (CAR) in predicting intermediate-high SYNergy between Percutaneous Coronary Intervention with TAXus and cardiac surgery (SYNTAX) score (SS) and high SS II. Consecutive patients (n = 344) treated with percutaneous coronary intervention comprised the study population. The study population was divided into 2 groups according to SS >22 and mean SS II values, respectively. Patients with intermediate-high SS and high SS II had higher CAR than patients with low SS and SS II. History of diabetes mellitus, decreased albumin, lower left ventricular ejection fraction, and elevated CAR (odds ratio [OR]: 1.020; 95% confidence interval [CI], 1.009-1.031; P < .001) were independent predictors of high SS. The presence of hypertension, decreased hemoglobin and albumin levels, and increased CAR (OR: 1.014; 95% CI, 1.004-1.023; P < .001) were independent predictors of SS II. In receiver operating characteristic curve comparison, CAR was superior to CRP and albumin in prediction of intermediate-high SS, but only CRP in prediction of high SS II. The CAR calculated from the admission blood samples could be a useful parameter for predicting CAD severity using SS and SS II. PMID- 29172654 TI - Carotid-Femoral Pulse Wave Velocity in the Prediction of Cardiovascular Events and Mortality: An Updated Systematic Review and Meta-Analysis. AB - Arterial stiffness (AS) is a predictor of coronary artery outcomes in patients with cardiovascular disease (CVD). Carotid-femoral pulse wave velocity (cf-PWV) is a commonly used method for assessing AS. This study aimed to assess the relationship between cf-PWV and clinical CVD events. Of the 786 studies identified, 19 studies were included in the final meta-analysis. Meta-analysis revealed that participants with high cf-PWV by 1 standard deviation (SD), 1 m/s, and cutoff points have a high pooled relative risk for CVD events (1 SD: 1.25, 95% confidence interval [CI]: 1.19-1.31; 1 m/s: 1.12, 95% CI: 1.07-1.18; and cutoff points: 1.80, 95% CI: 1.45-2.14) and CVD mortality (1 SD: 1.23, 95% CI: 1.15-1.31; 1 m/s: 1.09, 95% CI: 1.04-1.14; and cutoff points: 1.85, 95% CI: 1.46 2.24). In addition, we found that the predictive value of increased AS was higher in patients with higher disease risk for total CVD events and CVD mortality than in other patients. Carotid-femoral pulse wave velocity is a useful biomarker to improve the prediction of CV risk for patients and identify high-risk populations who may benefit from aggressive CV risk factor management.

AB - AIMS: The purpose of this study was to conduct a systematic review, and where applicable meta-analyses, examining the evidence underpinning the use of targeted temperature management following resuscitation from cardiac arrest. METHODS AND RESULTS: Multiple databases were searched for publications between January 2000 February 2016. Nine Population, Intervention, Comparison, Outcome questions were developed and meta-analyses were performed when appropriate. Reviewers extracted study data and performed quality assessments using Grading of Recommendations, Assessment, Development and Evaluation methodology, the Cochrane Risk Bias Tool, and the National Institute of Health Study Quality Assessment Tool. The primary outcomes for each Population, Intervention, Comparison, Outcome question were mortality and poor neurological outcome. Overall, low quality evidence demonstrated that targeted temperature management at 32-36 degrees C, compared to no targeted temperature management, decreased mortality (risk ratio 0.76, 95% confidence interval 0.61-0.92) and poor neurological outcome (risk ratio 0.73, 95% confidence interval 0.60-0.88) amongst adult survivors of out-of-hospital cardiac arrest with an initial shockable rhythm. Targeted temperature management use did not benefit survivors of in-hospital cardiac arrest nor out-of-hospital cardiac arrest survivors with a non-shockable rhythm. Moderate quality evidence demonstrated no benefit of pre-hospital targeted temperature management initiation. Low quality evidence showed no difference between endovascular versus surface cooling targeted temperature management systems, nor any benefit of adding feedback control to targeted temperature management systems. Low quality evidence suggested that targeted temperature management be maintained for 18-24 h. CONCLUSIONS: Low quality evidence supports the in-hospital initiation and maintenance of targeted temperature management at 32-36 degrees C amongst adult survivors of out-of-hospital cardiac arrest with an initial shockable rhythm for 18-24 h. The effects of targeted temperature management on other populations, the optimal rate and method of cooling and rewarming, and effects of fever require further study.

AB - Since the initial breaking discovery of Folling that the severe neurological consequences of phenylketonuria could be prevented by use of low phenylalanine (Phe) diet, it has been shortly recognised that defective phenylalanine metabolism may also arise from the deficiency of tetrahydrobiopterin (BH4) cofactor, required for phenylalanine-hydroxylase activity. Furthermore, as BH4 is in Phe metabolism, it is also a cofactor for the activities of tyrosine hydroxylase and tryptophane hydroxylase, enzymes required for the synthesis of catecholamines and serotonin neurotransmitters. Besides hyperphenylalaninemia in patients with tetrahydrobiopterin deficiencies, dopamine and serotonin deficiencies, with different disorders of the central nervous system also develop. Mild form of tetrahydrobiopterin deficiency is rare, most of the patients have severe neurological abnormalities including progressive mental retardation if not treated properly. Early diagnosis and treatment are essential and can improve the clinical course and prognosis. Orv Hetil. 2017; 158(48): 1897 1902.

AB - Inherited errors of metabolism are rare genetic disorders characterized by diverse clinical and biochemical phenotypes. The complexity of signs and symptoms often presents a challenge for both clinicians and laboratory specialists. In many cases, prevention of permanent neurological symptoms or death in patients presenting these disorders is dependent on early diagnosis and introduction of appropriate therapy. For professionals it is indispensable to be familiar with the major clinical signs of inborn errors of metabolism and with the necessary and available laboratory studies to achieve an early diagnosis. The review tries to give a way of approach, diagnostic algorithm of laboratory measurements for the correct diagnosis in inherited errors of metabolism. The combination of biochemical and clinical signs, results of special metabolic investigations represent a portentous challenge in general practice. For the correct diagnosis of an inherited error of metabolism, the teamwork between clinicians and laboratory specialists is indispensable. Orv Hetil. 2017; 158(48): 1903-1907. PMID- 29172661 TI - [Novelties in the treatment of pediatric immune thrombocytopenia - 2017]. AB - Immune thrombocitopenia in children is a very variable disease. International recommendations give therapeutic possibilities without strong protocols. In 2011, a therapeutic algorithm was published based on Hungarian practice. Recently, new innovative drugs have been available even in Hungary, so there is a need for modification of the therapeutic protocols. In this summary we give an overview about the current up-to-date management. In infancy and in childhood, high-dose immunglobulin treatment is recommended henceforward. In older children an alternative can be steroid therapy (pulses or long-term low-dose treatment). In resistant cases, a new thrombopoetin receptor stimulant, eltrombopag can be administered. This drug is registered in Hungary, and can very effectively influence the prognosis. Splenectomy is very rare nowadays in children. Immune thrombocytopenia is an unpredictable disease. Cure rate is about 70-80% of the cases, but management of the patients needs special care and specialist. Orv Hetil. 2017; 158(48): 1891-1896. PMID- 29172662 TI - [Maternal and neonatal vitamin B12 deficiency detected by expanded newborn screening]. AB - INTRODUCTION: Infant vitamin B12 deficiency can manifest as a severe neurodegenerative disorder and is usually caused by maternal deficiency due to vegetarian diet or pernicious anaemia. Its early recognition and treatment can prevent potentially serious and irreversible neurologic damage. Biochemically, vitamin B12 deficiency leads to an accumulation of methylmalonic acid, homocysteine, and propionylcarnitine. Expanded newborn screening using tandem mass spectrometry may identify neonatal and maternal vitamin B12 deficiency by measurement of propionylcarnitine and other metabolites in the dried blood spot sample of newborns. AIM: To summarize our experiences gained by screening for vitamin B12 deficiency. METHOD: Clinical and laboratory data of vitamin B12 deficient infants diagnosed in Szeged Screening Centre were retrospectively analysed. RESULTS: In Hungary, expanded newborn screening was introduced in 2007. Since then approximately 395 000 newborns were screened in our centre and among them, we identified four newborns with vitamin B12 deficiency based on their screening results. In three cases an elevated propionylcarnitine level and in the fourth one a low methionine level were indicative of vitamin B12 deficiency. We also detected an additional vitamin B12-deficient infant with neurological symptoms at 4 months of age, after a normal newborn screening, because of elevated urinary methylmalonic acid concentration. Vitamin B12 deficiency was secondary to maternal autoimmune pernicious anaemia in all the five infants. As a result of the recognized cases the incidence of infant vitamin B12 deficiency in the East-Hungarian region was 1.26/100 000 births, but the real frequency may be higher. Conslusions: Optimizing the cut off values of current screening parameters and measuring of methylmalonic acid and/or homocysteine in the dried blood spot, as a second tier test, can improve recognition rate of vitamin B12 deficiency.

AB - The effect of mercury stress on antioxidant enzymes, lipid peroxidation, photosynthetic pigments, hydrogen peroxide content, osmolytes, and growth parameters in Tartary buckwheat were investigated. The effect of Hg-exposure was found to be time (15 and 30 days) and concentration (0, 25, 50, and 75 MUM) dependent. Hg was readily absorbed by seedlings with higher content in roots and it resulted in reduction of root and shoot length. The root and shoot Hg uptakes were significantly and directly correlated with each other. However, the fresh mass and biomass increased up to 50 MUM Hg-treatment at both time periods. A significant positive correlation was observed between biomass accumulation with relative water content. Hg levels were positively correlated with the production of hydrogen peroxide in leaves as evidenced by 3, 3-diaminobenzidine (DAB) mediated tissue fingerprinting. The osmolyte levels in general were elevated except for proline and protein which showed a decline at 75 MUM Hg-treatment at 30-days. Amongst the photosynthetic pigments, chlorophyll showed a decline while as carotenoid and anthocyanin levels were elevated. The activity of antioxidant enzymes such as ascorbate peroxidase (APX), guaiacol peroxidase (POD), glutathione reductase (GR), Glutathione-s-transferase (GST) and superoxide dismutase (SOD) were positively correlated with Hg-treatment except SOD, which declined at 75 MUM Hg-treatment in 30-days old seedlings. Catalase (CAT) activity showed a positive correlation up to 50 MUM Hg-treatment but at 75 MUM Hg-stress it decreases at both 15 and 30 days. PMID- 29172664 TI - Knowledge, Activation, and Costs of the Pharmacists' Pneumonia Prevention Program (PPPP): A Novel Senior Center Model to Promote Vaccination. AB - BACKGROUND: Vaccination is the best way to prevent pneumococcal disease (PD), but 40% of older adults remain unvaccinated nationwide, with even greater nonvaccination rates among African Americans (AAs). Prior studies suggest that insufficient knowledge contributes to low vaccination rates. The Pharmacists' Pneumonia Prevention Program (PPPP) was designed to improve older adults' knowledge about PD and pneumococcal vaccination (PV). OBJECTIVE: To measure PPPP's effect on knowledge and activation in a predominantly AA population and determine program costs. METHODS: PPPP uses a senior center model with a pharmacist presentation, actors' skit, and small-group action planning. Knowledge about PD risk, transmission, symptoms, and PV side effects was assessed at baseline (BL), postintervention (PT), and 3 months (M3) and analyzed using an intention-to-treat (ITT) approach. Actions taken (got vaccinated, spoke to doctor or pharmacist, discussed with family/friends) were assessed at M3. PPPP costs ($US 2013) included staff time, PV, actor, and site fees. RESULTS: Of 276 attending PPPP, 190 consented and were included in the ITT sample, which was largely black (80.5%) and female (76.3%) and had a mean age of 74.4 years. Knowledge improved by 46.8% (BL vs PT), with significant gains in all domains. At M3, knowledge improved by 54.2% vs BL, indicating sustained gains; 37.2% of previously unvaccinated participants reported receiving PV by M3. Program cost was $119 per attendee. CONCLUSION: PPPP significantly improved PD and PV knowledge. It could be delivered more efficiently by holding larger events on fewer dates, staffing with volunteers where appropriate, and utilizing a local pharmacy to manage the vaccine supply. PMID- 29172665 TI - Group analysis identifies differentially elevated biomarkers with distinct outcomes for advanced acute kidney injury in cardiac surgery. AB - AIM: To investigate early postoperative biomarkers for risk discrimination of advanced acute kidney injury (AKI). MATERIALS & METHODS: Postoperative plasma biomarkers including NGAL, h-FABP, CK-MB, hsTNT, NT-proBNP, IL-6, IL-10 and VEGF were analyzed using group-based method among 426 patients with AKI after cardiac surgery. RESULTS: Six patient groups with distinct biomarker patterns were identified. Individual biomarker displayed significant difference across the groups. The groups showed better discrimination for advanced AKI than any single biomarker either with or without adjusting for clinical variables. Average concentration of a single biomarker within each group, mortality and risk of a secondary outcome all demonstrated an approximately U-shaped relationship with proportion of advanced AKI within each group. CONCLUSION: The group-based analysis revealed that the order of the patient groups with an increasing likelihood of advanced AKI had a nonlinear relationship with average concentration of an individual biomarker, mortality and risk of other outcomes.

AB - Olfaction is a key sensory mechanism in humans. Deficits in this chemosensory function have wide-ranging impacts on overall health and quality of life. This study examines the role of environmental phenols as risk factors for olfactory dysfunction among a random sample of 839 middle-aged and older U.S. adults. Olfactory function assessment was carried out using a short 8-item test, scores on which were used to classify subjects into normal or impaired olfactory function groups. Logistic regression models were used to test for associations between olfactory impairment and creatinine-adjusted urinary levels of 8 common environmental phenols, adjusting for potentially confounding covariates. A statistically significant association between 2,4-dichlorophenol levels and olfactory impairment (OR = 1.02 [95 % CI: (1.003, 1.04)]; p = 0.02) was found. 2,4-dichlorophenol is a hazardous pollutant with widespread exposure via industrial and indoor air pollution, diet, and the use of pesticides and herbicides. This study is the first to reveal its role in olfactory impairment. PMID- 29172667 TI - Reflections on the history of bareback sex through ethnography: the works of subjectivity and PrEP. AB - Throughout the history of bareback sex (condomless sex between men), 'subjects' have been created, particularly through scientific literature, to characterise the men who engage in the sexual practice. For example, a gay man who does not use a condom may be framed as a pathologised subject. This paper first presents this history. Afterwards, by relying upon ethnographic data such as interviews collected from fieldwork research done in Toronto in 2014 with young gay men who have bareback sex, it shows exactly how these young gay men related themselves to those subjects. Then, it focuses on the pre-exposure prophylaxis (PrEP) Truvada as a new HIV prevention technology. Although PrEP can allow condomless sex to occur while diminishing the risk of HIV transmission, at the time of the research, none of the young gay men were interested in using this tool despite being the subjects for whom the drug is tailored. This paper argues that PrEP and subjectivity are coproduced and can have conflicting meanings. This contradiction of meanings is a result of the various representations and symbols of bareback sex and the men who engage in the practice that have been produced throughout the history of bareback sex. PMID- 29172668 TI - Symmetrical Parameterization of Rigid Body Transformations for Biomolecular Structures. AB - Assessing preferred relative rigid body position and orientation is important in the description of biomolecular structures (such as proteins) and their interactions. In this article, we extend and apply the "symmetrical parameterization," which we recently introduced in the kinematics community, to address problems in structural biology. We also review parameterization methods that are widely used in structural biology to describe relative rigid body motions (in particular, orientations) as a basis for comparison. The new symmetrical parameterization is useful in describing the relative biomolecular rigid body motions, where the parameters are symmetrical in the sense that the subunits of a complex biomolecular structure are described in the same way for the corresponding motion and its inverse. The properties of this new parameterization, singularity analysis, and inverse kinematics are also investigated in more detail. Finally, parameterization is applied to real biomolecular structures and a potential application to structure modeling of symmetric macromolecules to show the efficacy of the symmetrical parameterization in the field of computational structural biology. PMID- 29172669 TI - Long-term Effect of Injection Treatment for Osteoarthritis in the Knee by Orthokin Autologous Conditioned Serum. AB - Background Orthokin is an intra-articular autologous conditioned serum (ACS). Its use might have a beneficial biological effect on pain and function of osteoarthritis in the knee. However, earlier studies lack any consensus on its clinical application and disease modifying effect. Objective The aim of this study was to investigate the long-term effect of Orthokin injection treatment on prevention of surgical treatment for end-stage knee osteoarthritis. Study Design Prospective cohort study. Methods Patients of the previously published Orthokin cohort were contacted to determine whether any intra-articular surgical intervention or osteotomy of the study knee had taken place during the past decade. A log-rank test was performed to evaluate the differences in the survival distribution for the 2 types of intervention: Orthokin versus placebo. Results The survival distributions for the 2 interventions were not statistically significantly different, chi2(1) = 2.069, P = 0.150. After 7.5 +/- 3.9 years, 46.3% of the placebo and 40.3% of the Orthokin group had been treated surgically. Conclusion The use of Orthokin in knee osteoarthritis patients did not result in a delay regarding surgical treatment. Clinical Relevance The intra-articular use of Orthokin does not seem to prevent or delay surgical intervention at 10 years after treatment for end-stage knee osteoarthritis. PMID- 29172670 TI - Predicting tuberculosis treatment outcome using metabolomics. AB - AIM: Predicting a poor treatment outcome would offer significant benefits for patient care and for new drug development. Materials, methods & results: Urine samples from tuberculosis-positive patients with a successful and unsuccessful treatment outcome were collected at baseline and analyzed. The identified metabolites were used in a forward logistic regression model, which achieved a receiver operating characteristic area under the curve of 0.94 (95% CI: 0.84-1) and cross-validated well in a leave-one-out context, with an area under the curve of 0.89 (95% CI: 0.7-1). Two possible predictors were identified, which are associated with a gut microbiota imbalance. DISCUSSION & CONCLUSION: Our findings show the capacity of metabolomics to predict treatment failure at the time of diagnosis, which potentially offers significant benefits for the use in new drug development clinical trials and individualized patient care. PMID- 29172672 TI - platelet-lymphocyte ratio in prediction of outcome of acute heart failure. AB - AIM: To examine the role of the ratios of platelet or neutrophil to lymphocyte count (PLR or NLR) in predicting hospital death and long-term mortality in acute heart failure (AHF). Methods & materials: The records of 554 admissions from 354 patients discharged from VAWNY with AHF between 2011 and 2015 were reviewed. The associations between admission PLR or NLR and hospital and long-term mortality were assessed by univariate and multivariate analyses. RESULTS: PLR was similar regarding hospital mortality. Long-term mortality was higher in the third tertile PLR (PLR >210; p = 0.034). Neither PLR nor NLR was an independent predictor of mortality. CONCLUSION: Although higher PLR was associated with long-term mortality, it failed to independently predict the prognosis of AHF.

An Examination of the Agreement Between the Adult Attention Deficit/Hyperactivity Disorder Self-Report Scale V1.1 and Adult Attention Deficit/Hyperactivity Disorder Investigator Symptom Rating Scale. AB - OBJECTIVES: Assess agreement between self-ratings via the adult attention deficit/hyperactivity disorder (ADHD) Self-Report Scale (ASRS)-v1.1 Symptom Checklist and clinician ratings via the adult ADHD Investigator Symptom Rating Scale (AISRS) expanded version using DSM-5 adult ADHD patients (referred sample) and ADHD controls (recruited from a primary care physician practice). METHODS: The ASRS v1.1 Symptom Checklist was administered to measure self-reported ADHD symptoms and impairment, the Adult ADHD Clinical Diagnostic Scale v1.2 was used to establish an adult ADHD diagnosis and the childhood and adult/current sections of the scale were used to provide scores to measure symptoms of childhood ADHD and recent symptoms of adult ADHD, the AISRS to measure ADHD current symptom severity. RESULTS: Participants (n = 299; range 18-58), of which 171 were ADHD+ and 128 ADHD-. ASRS and AISRS total scores and individual subsections examining inattention, hyperactivity, emotional dysfunction (EF), and emotional dyscontrol (EC) were all significantly correlated (Spearman's rho's = 0.78-0.89, ps < 0.01). Correlations remained significant when controlling for demographic factors and psychiatric conditions. CONCLUSIONS: The ASRS (self) and AISRS (clinician rated) scales have high agreement. This agreement extended not only the to the core 18 DSM symptoms, but also to the additional 13 symptoms that examine EC and EF. PMID- 29172671 TI - Pulmonary quantitative CT imaging in focal and diffuse disease: current research and clinical applications. AB - The frenetic development of imaging technology-both hardware and software provides exceptional potential for investigation of the lung. In the last two decades, CT was exploited for detailed characterization of pulmonary structures and description of respiratory disease. The introduction of volumetric acquisition allowed increasingly sophisticated analysis of CT data by means of computerized algorithm, namely quantitative CT (QCT). Hundreds of thousands of CTs have been analysed for characterization of focal and diffuse disease of the lung. Several QCT metrics were developed and tested against clinical, functional and prognostic descriptors. Computer-aided detection of nodules, textural analysis of focal lesions, densitometric analysis and airway segmentation in obstructive pulmonary disease and textural analysis in interstitial lung disease are the major chapters of this discipline. The validation of QCT metrics for specific clinical and investigational needs prompted the translation of such metrics from research field to patient care. The present review summarizes the state of the art of QCT in both focal and diffuse lung disease, including a dedicated discussion about application of QCT metrics as parameters for clinical care and outcomes in clinical trials. PMID- 29172674 TI - Single nucleotide polymorphisms in TNF are associated with susceptibility to aspirin-exacerbated respiratory disease but not to cytokine levels: a study in Mexican mestizo population. AB - AIM: To evaluate the association of three single nucleotide polymorphisms in TNF and one in LTA in Mexican patients with aspirin-exacerbated respiratory disease (AERD) and the correlation of those single nucleotide polymorphisms with serum levels of TNF-alpha. PATIENTS & METHODS: Case-control study including 133 patients with AERD, 135 patients with asthma (aspirin-tolerant asthmatics) and 182 healthy subjects. RESULTS: GA genotype of rs1800629 in TNF was found to be associated with the risk of developing AERD (p < 0.05; odds ratio = 2.36) and by dominant model (p < 0.05; odds ratio = 2.51). Furthermore, there was a difference in the serum levels between the aspirin-tolerant asthmatics group and the other groups (p < 0.001). CONCLUSION: The GA genotype of rs1800629 is associated with genetic susceptibility to AERD, but it does not correlate to protein serum levels. PMID- 29172675 TI - Immune-related tumour response assessment criteria: a comprehensive review. AB - Growing emphasis on precision medicine in oncology has led to increasing use of targeted therapies that encompass a spectrum of drug classes including angiogenesis inhibitors, immune modulators, signal transduction inhibitors, DNA damage modulators, hormonal agents etc. Immune therapeutic drugs constitute a unique group among the novel therapeutic agents that are transforming cancer treatment, and their use is rising. The imaging manifestations in patients on immune therapies appear to be distinct from those typically seen with conventional cytotoxic therapies. Patients on immune therapies may demonstrate a delayed response, transient tumour enlargement followed by shrinkage, stable size, or initial appearance of new lesions followed by stability or response. These newer patterns of response to treatment have rendered conventional criteria such as World Health Organization and response evaluation criteria in solid tumours suboptimal in monitoring changes in tumour burden. As a consequence, newer imaging response criteria such as immune-related response evaluation criteria in solid tumours and immune-related response criteria are being implemented in many trials to effectively monitor patients on immune therapies. In this review, we discuss the traditional and new imaging response criteria for evaluation of solid tumours, review the outcomes of various articles which compared traditional criteria with the new immune-related criteria and discuss pseudo-progression and immune-related adverse events.

Then, birds were weighed and used in a completely randomised design experiment with a 3 * 3 factorial arrangement, including three levels of conditioning times (0, 2 and 4 min) and three PSB levels (0, 7.5 and 15 g/kg diet). Each of the 9 diets fed to 6 replicates group of 15 birds each. 3. The results showed that 2-min steam conditioning and 15 g/kg PSB supplementation significantly increased pellet durability index (PDI) and hardness, and decreased electrical consumption of pelleting. Diets had no significant effects on body weight, feed intake and feed conversion ratio. Although dietary treatments did not influence relative weight and length of three segments of small intestine, 2-min steam conditioning significantly improved villus height (VH) and crypt depth. Steam conditioning of diet for 2 min significantly increased apparent metabolisable energy (AME), ether extract (EE), calcium (Ca) and dry matter (DM) retention in birds measured during 38-42 d of age. 4. It could be concluded that 2-min steam conditioning improved PDI and hardness, VH and nutrient retention (AME, EE, Ca and DM), but did not affect growth performance in broilers during finisher period. PMID- 29172678 TI - Commentary: how will interventional oncology navigate the "valleys of death" for new medical devices? AB - Whereas clinical trials of cancer drugs have methodological standards and conventional primary endpoints, these are not necessarily applicable to the clinical development of loco-regional treatments and new medical devices. The current challenge is to generate high-level clinical evidence for loco-regional treatments to define the benefits for patients. In this article, we argue that, to generate convincing evidence of clinical efficacy and safety, the collective coherence of the entire data package is often more important than the primary endpoint of one clinical trial. We also propose that, when a comprehensive clinical data package is not feasible, limited clinical data can be supplemented with other types of evidence. Emerging life science companies often define the "valley of death" after securing initial investment to translate an early medical device concept to a development stage that is attractive to funders. Unfortunately for this industry, there is a second "valley of death" if the focus and goal is only regulatory approval, to the neglect of clinical acceptance and reimbursement. For the emerging specialism of interventional oncology, it is critical to plan a clear line of sight for each new medical device to avoid the valleys of death and to demonstrate the clinical benefit. Increased international guidance to establish realistic yet convincing standards in this area may avoid attrition of potentially beneficial devices and therapeutic procedures in the valleys of death.

AB - Familial hypercholesterolemia (FH) is a metabolic disorder that leads primarily to premature cardiovascular diseases, the main cause of mortality in Saudi Arabia (SA). FH is underreported and underdiagnosed in SA with statistical evidence of high expected prevalence in such a consanguineous community. Lacking knowledge of which and how these alterations are actually impacting lipid metabolism is one of the main reasons why FH is insufficiently diagnosed in the region. The aim of this study was to develop a fast prediction approach using an integrated bioinformatics method for future screening of the potential causative variants from national registries. A total of 21 variants were detected with majority rate in LDLR (81%). Variants were classified based on the type of mutation. Missense variants resulting in amino acid changes, c.1429G>A (p.D477N), c.1474G>A (p.D492N), c.1731G>T (p.W577C), and c.1783C>T (p.R595W) in LDLR gene, in addition to c.9835A>G (p.S3279G) in APOB, were shown to be deleterious by concordant analysis. Furthermore, functional interaction deformities showed a significant loss and gain of energies in the mutated proteins. These findings will help in distinguishing the most harmful mutations needed to be screened for clinically diagnosed FH patients in SA. Such computational research is necessary to avoid time consumption and the usage of expensive biological experiments. This can be a fast track to facilitate the future filtering and screening of causative mutations from national registries. PMID- 29172680 TI - Efficacy and Safety of HLD200, Delayed-Release and Extended-Release Methylphenidate, in Children with Attention-Deficit/Hyperactivity Disorder. AB - OBJECTIVE: Evening-dosed HLD200 is a delayed-release and extended-release methylphenidate (DR/ER-MPH) formulation consisting of uniform, dual-layered microbeads with an inner drug-loaded core. DR/ER-MPH is designed to delay the initial release of drug by 8-10 hours, and thereafter, provide a controlled, extended drug release to target onset of effect upon awakening that lasts into the evening. This phase 3 study evaluated the safety and efficacy of DR/ER-MPH on symptoms and temporal at-home functional impairment in children with attention deficit/hyperactivity disorder (ADHD). METHODS: This 3-week, randomized, double blind, multicenter, placebo-controlled, parallel-group, forced-dose titration trial evaluated DR/ER-MPH (40-80 mg/day) in children aged 6-12 years with ADHD. Primary efficacy endpoint was the ADHD rating scale-IV (ADHD-RS-IV), and the key secondary endpoints were the Before-School Functioning Questionnaire (BSFQ), and Parent Rating of Evening and Morning Behavior-Revised, morning (PREMB-R AM) and evening (PREMB-R PM). Safety measures included spontaneously reported treatment emergent adverse events (TEAEs) and two TEAEs of special interest, appetite suppression and insomnia (with direct questioning on sleep disturbance). RESULTS: One hundred sixty-one participants were included in the intent-to-treat population (DR/ER-MPH, n = 81; placebo, n = 80). After 3 weeks, DR/ER-MPH achieved significant improvements versus placebo in ADHD symptoms (least-squares [LS] mean ADHD-RS-IV: 24.1 vs. 31.2; p = 0.002), and at-home early morning (LS mean BSFQ: 18.7 vs. 28.4; p < 0.001; LS mean PREMB-R AM: 2.1 vs. 3.6; p < 0.001) and late afternoon/evening (LS mean PREMB-R PM: 9.4 vs. 12.2; p = 0.002) functional impairment. Commonly reported TEAEs (>=10%) were insomnia and decreased appetite. CONCLUSIONS: DR/ER-MPH was generally well tolerated and demonstrated significant improvements versus placebo in ADHD symptoms and at-home functional impairments in the early morning, late afternoon, and evening in children with ADHD. PMID- 29172681 TI - Further Analysis of the Predictive Effects of a Free-Operant Competing Stimulus Assessment on Stereotypy. AB - We conducted five experiments to evaluate the predictive validity of a free operant competing stimulus assessment (FOCSA). In Experiment 1, we showed that each participant's repetitive behavior persisted without social consequences. In Experiment 2, we used the FOCSA to identify high-preference, low-stereotypy (HP LS) items for 11 participants and high-preference, high-stereotypy (HP-HS) items for nine participants. To validate the results of the FOCSAs (Experiment 3), we used a three-component multiple schedule to evaluate the immediate and subsequent effects of an HP-LS stimulus, an HP-HS stimulus, or both (in separate test sequences) on each participant's stereotypy. Results of Experiment 3 showed that the FOCSA correctly predicted the immediate effect of the HP-LS stimulus for 10 of 11 participants; however, the FOCSA predictions were less accurate for the HP HS stimulus. Results of Experiment 4 showed that a differential reinforcement of other behavior procedure in which participants earned access to the HP-LS for omitting vocal stereotypy increased all five participants' latency to engaging in stereotypy; however, clinically significant omission durations were only achieved for one participant. Experiment 5 showed that differential reinforcement of alternative behavior in which participants earned access to the HP-LS stimulus contingent upon correct responses during discrete-trial training reduced targeted and nontargeted stereotypy and increased correct academic responding for all four participants. The potential utility of the FOCSA is discussed. PMID- 29172683 TI - New technique of percutaneous CT fluoroscopy-guided marking before video-assisted thoracoscopic surgery for small lung lesions: feasibility of using a 25-gauge needle without local anaesthesia. AB - OBJECTIVE: To retrospectively evaluate the feasibility of CT fluoroscopy-guided percutaneous marking using a 25-gauge needle and indigo carmine before video assisted thoracoscopic surgery (VATS) for small lung lesions. METHODS: 21 patients, 14 males and 7 females, with a median age of 69 years (range, 40-79), underwent CT fluoroscopy-guided percutaneous VATS marking using a 25-gauge, 70-mm needle and 1.5-ml indigo carmine. The mean diameter of the lung lesions was 14 mm (range, 6-27). We evaluated the technical success rate, surgical success rate and complications related to this procedure by reviewing medical records and images. Technical success was defined as completion of this procedure. Surgical success was defined as resection of the target lesion with negative margins on pathological examination after VATS. Complications that required advanced levels of care were classified as major complications, and the remaining complications were considered minor. RESULTS: The technical success rate was 100%. In all cases, VATS was successfully performed as planned, and the target lesion was resected with negative margins on pathological examination after VATS. Thus, the surgical success rate was 100%. Mild pneumothorax was found in two cases, but further treatment was not required. The minor complication rate was 9.5% (2/21), and major complication rate was 0%. Only two patients (9.5%) complained of slight pain upon puncture, but local anaesthesia was not required. CONCLUSION: Percutaneous CT fluoroscopy-guided VATS marking using a 25-gauge needle without local anaesthesia appears feasible and safe. Advances in knowledge: This technique expands a possibility of the CT-guided marking. PMID- 29172682 TI - Impact of Specimen Heterogeneity on Biomarkers in Repository Samples from Patients with Acute Myeloid Leukemia: A SWOG Report. AB - INTRODUCTION: Current prognostic models for acute myeloid leukemia (AML) are inconsistent at predicting clinical outcomes for individual patients. Variability in the quality of specimens utilized for biomarker discovery and validation may contribute to this prognostic inconsistency. METHODS: We evaluated the impact of sample heterogeneity on prognostic biomarkers and methods to mitigate any adverse effects of this heterogeneity in 240 cryopreserved bone marrow and peripheral blood specimens from AML patients enrolled on SWOG (Southwest Oncology Group) trials. RESULTS: Cryopreserved samples displayed a broad range in viability (37% with viabilities <=60%) and nonleukemic cell contamination (13% with lymphocyte percentages >20%). Specimen viability was impacted by transport time, AML immunophenotype, and, potentially, patients' age. The viability and cellular heterogeneity in unsorted samples significantly altered biomarker results. Enriching for viable AML blasts improved the RNA quality from specimens with poor viability and refined results for both DNA and RNA biomarkers. For example, FLT3 ITD allelic ratio, which is currently utilized to risk-stratify AML patients, was on average 1.49-fold higher in the viable AML blasts than in the unsorted specimens. CONCLUSION: To our knowledge, this is the first study to provide evidence that using cryopreserved specimens can introduce uncontrollable variables that may impact biomarker results and enrichment for viable AML blasts may mitigate this impact. PMID- 29172684 TI - Faster and safer? FLASH ultra-high dose rate in radiotherapy. AB - Recent results from the Franco-Swiss team of Institute Curie and Centre Hospitalier Universitaire Vaudois demonstrate a remarkable sparing of normal tissue after irradiation at ultra-high dose rate (>40 Gy s-1). The "FLASH" radiotherapy maintains tumour control level, suggesting that ultra-high dose rate can substantially enhance the therapeutic window in radiotherapy. The results have been obtained so far only with 4-6 MeV electrons in lung and brain mouse model. Nevertheless, they have attracted a great attention for the potential clinical applications. Oxygen depletion had been discussed many years ago as a possible mechanism for reduction of the damage after exposure to ultra-high dose rate. However, the mechanism underlying the effect observed in the FLASH radiotherapy remains to be elucidated. PMID- 29172685 TI - Attempts to redefine conflicts of interest. AB - The traditional legal concept of conflict of interest is a practical tool to regulate conduct. In recent years several medical authors have defined conflicts of interest in ways that stray from its original legal meaning. The new definitions cause conceptual confusion and will result in policies that cannot be implemented effectively. We should not follow recent attempts to redefine conflicts of interest because doing so deviates from the legal concept and will lead to deregulation of financial conflicts and overregulation of so-called intellectual conflicts. PMID- 29172686 TI - Prenylated flavonoids and dihydrophenanthrenes from the leaves of Epimedium brevicornu and their cytotoxicity against HepG2 cells. AB - Phytochemical study on the leaves of Epimedium brevicornu finally led to the isolation of four prenylated flavonoids (1-4) and three dihydrophenanthrenes (5 7), of which 1, 2, 5 and 7 were new compounds. The structures of these compounds were established mainly by spectroscopic techniques, including NMR spectroscopy and mass spectrometry. These isolates exhibited the cytotoxic activities against HepG2 cells with the IC50 values of 32.8-87.3 MUM. PMID- 29172687 TI - European cardiovascular nurses' and allied professionals' knowledge and practical skills regarding cardiopulmonary resuscitation. AB - PURPOSE: Cardiopulmonary resuscitation (CPR) remains a cornerstone in the treatment of cardiac arrest, and is directly linked to survival rates. Nurses are often first responders and need to be skilled in the performance of cardiopulmonary resuscitation. As cardiopulmonary resuscitation skills deteriorate rapidly, the purpose of this study was to investigate whether there was an association between participants' cardiopulmonary resuscitation training and their practical cardiopulmonary resuscitation test results. METHODS: This comparative study was conducted at the 2014 EuroHeartCare meeting in Stavanger ( n=133) and the 2008 Spring Meeting on Cardiovascular Nursing in Malmo ( n=85). Participants performed cardiopulmonary resuscitation for three consecutive minutes CPR training manikins from Laerdal Medical(r). Data were collected with a questionnaire on demographics and participants' level of cardiopulmonary resuscitation training. RESULTS: Most participants were female (78%) nurses (91%) from Nordic countries (77%), whose main role was in nursing practice (63%), and 71% had more than 11 years' experience ( n=218). Participants who conducted cardiopulmonary resuscitation training once a year or more ( n=154) performed better regarding ventilation volume than those who trained less (859 ml vs. 1111 ml, p=0.002). Those who had cardiopulmonary resuscitation training offered at their workplace ( n=161) also performed better regarding ventilation volume (889 ml vs. 1081 ml, p=0.003) and compression rate per minute (100 vs. 91, p=0.04) than those who had not. CONCLUSION: Our study indicates a positive association between participants' performance on the practical cardiopulmonary resuscitation test and the frequency of cardiopulmonary resuscitation training and whether cardiopulmonary resuscitation training was offered in the workplace. Large ventilation volumes were the most common error at both measuring points. PMID- 29172688 TI - Effect of nanoparticle treatment on expression of a key gene involved in thymoquinone biosynthetic pathway in Nigella sativa L. AB - Thymoquinone is the most important secondary metabolite in black Cumin, which has several pharmaceutical applications. In this study, effect of TiO2 and SiO2 nanoparticles as new elicitors, on expression of Geranyl diphosphate synthase gene (GPPS gene), as a key gene involved in thymoquione biosynthesis pathway was investigated in two Iranian accessions. Plants were treatment in the early flowering stage and after 24 h of 50 and 100 mg/L of each nanoparticle, separately. After RNA extraction, GPPS gene expression was analysed by qRT-PCR method. The results showed that the TiO2 and SiO2 nanoparticles, generally stimulates the GPPS expression. The TiO2 nanoparticles were more effective than SiO2 for the induction of GPPS expression. Also, 100 mg/L treatment of nanoparticles raised gene expression more than 50 mg/L concentration. It can be concluded these nanoparticles can be used as robust elicitors to enhance the production of Thymoquinone in black cumin through up-regulation of related metabolic pathway genes. PMID- 29172689 TI - Stress Fracture of the Fifth Metatarsal in Foot Deformity Secondary to Neuromuscular Disease: Experiences of Deformity Correction Treatment-A Report of 3 Cases and Review of the Literature. AB - : Fractures at the proximal metaphyso-diaphyseal junction of the fifth metatarsal are associated with high rates of delayed union. When these fractures are the result of repeated stress in patients with equinovarus hindfoot, which in turn is caused by neurological disorders, delayed union is the rule. Therefore, in neurological patients with stress fractures, optimal treatment would be to achieve a plantigrade foot enabling them to relieve the fifth metatarsal overload, which prevents the consolidation. We report 3 cases of fifth metatarsal stress fracture resulting from an equinovarus hindfoot deformity caused by a neuromuscular disease. Our surgical indication was to correct the foot deformity with no direct action on the fracture. Once a good alignment (plantigrade foot) was obtained, stress causing the fracture disappeared, and union was achieved with optimal biomechanical function in all 3 fractures. When stress fracture of the fifth metatarsal is caused by a secondary foot deformity, treating the deformity can lead to healing the fracture efficiently and should be considered prior to indicating surgical stabilization of the fracture itself. Primary treatment of the fracture with no correction of the deformity leads to therapeutic failure. LEVELS OF EVIDENCE: Therapeutic, Level IV.

PMID- 29172691 TI - Two new sesquiterpenes derivatives from marine fungus Leptosphaerulina Chartarum sp. 3608. AB - Two new sesquiterpenes, leptoterpenes A (1) and B (2) were isolated from the fungus Leptosphaerulina Chartarum sp. 3608, derived from a crinoid. It was the first chemical study on this species. The structures of these compounds were elucidated by spectroscopic methods including NMR and MS spectrometry. The absolute configurations of the new compounds were determined on the basis of the single-crystal X-ray diffraction and electronic circular dichroism data analysis. All compounds were tested for their anti-inflammatory activity and the inhibitory effects on Tyrosyl DNA phosphodiesterase II (TDP2). PMID- 29172692 TI - Phenolic profiles of Serbian autochthonous variety 'Prokupac' and monovarietal international wines from the Central Serbia wine region. AB - Phenolic profiles of young monovarietal white and red wines from the Central Serbia were investigated. Quantification of phenolics was done using ultra-high performance liquid chromatography (UHPLC) coupled with a diode array detector and a triple-quadrupole mass spectrometer. Generally, red wines were characterised with higher phenolics content when compared to the white wines. This applies also for the total phenolics content (TPC) and radical scavenging activity (RSA) values. Among all the samples, the red wine from autochthonous Serbian variety 'Prokupac' stood out with unique composition, showing the highest TPC, RSA and the highest concentration of the individual phenolics. Finally, based on a specific phenolic pattern, principal component analysis (PCA) indicated clustering of red and white wines, with the 'Prokupac' as a prominent outlier. PMID- 29172693 TI - Ephedrine as a lead compound for the development of new DPP-IV inhibitors. AB - AIM: Extracts from Ephedra species have been reported to be effective as antidiabetics. A previous in silico study predicted that ephedrine and five ephedrine derivatives could contribute to the described antidiabetic effect of Ephedra extracts by inhibiting dipeptidyl peptidase IV (DPP-IV). Finding selective DPP-IV inhibitors is a current therapeutic strategy for Type 2 diabetes mellitus management. Therefore, the main aim of this work is to experimentally determine whether these alkaloids are DPP-IV inhibitors. Materials & methods: The DPP-IV inhibition of Ephedra's alkaloids was determined via a competitive-binding assay. Then, computational analyses were used in order to find out the protein ligand interactions and to perform a lead optimization. RESULTS: Our results show that all six molecules are DPP-IV inhibitors, with IC50 ranging from 124 MUM for ephedrine to 28 mM for N-methylpseudoephedrine. CONCLUSION: Further computational analysis shows how Ephedra's alkaloids could be used as promising lead molecules for designing more potent and selective DPP-IV inhibitors. PMID- 29172694 TI - Epigenetic profiles in polyglutamine disorders. AB - The dominant polyglutamine (polyQ) disorders are a group of progressive and incurable neurodegenerative disorders, which are caused by unstable expanded CAG trinucleotide repeats in the coding regions of their respective causative genes. The most prevalent polyQ disorders worldwide are Huntington's disease and spinocerebellar ataxia type 3. Epigenetic mechanisms, such as DNA methylation, histone modifications and chromatin remodeling and noncoding RNA regulation, regulate gene expression or genome function. Epigenetic dysregulation has been suggested to play a pivotal role in the pathogenesis of polyQ disorders. Here, we summarize the current knowledge of epigenetic changes present in several representative polyQ disorders and discuss the potentiality of miRNAs as therapeutic targets for the clinic therapy of these disorders. PMID- 29172696 TI - Evaluation of Empowerment in Health Promotion Interventions: A Systematic Review. AB - Although empowerment is one of the core principles of the World Health Organization's approach to health promotion, there are no standards, best practice recommendations, or guidelines for evaluating empowerment within interventions. For the development of effective empowerment promoting interventions, adequate study designs, methods, and indicators for assessing empowerment are essential. In order to better understand which evaluation procedures have been used so far, and which advantages and disadvantages are connected to them, we systematically reviewed empowerment-based health promotion interventions. We included 26 studies, which use a broad variety of quantitative, qualitative, and mixed-methods designs and various data collection methods; qualitative and mixed-methods designs predominated. The quantitative measurement instruments are heterogeneous: Mainly self-designed or modified scales are applied. All studies consider indicators reflecting individual competencies and motivations, whereas indicators capturing the organizational and political components of empowerment are less common. Involving target group members in the development of evaluation procedures and combining different data sources are mentioned as specific steps to improve the quality of data collection. Given the flexible and context-dependent nature of empowerment approaches, the development of a "gold standard" for its evaluation seems unrealistic. However, the analyzed studies can be used to deduce recommendations that may help to conduct high quality evaluations of empowerment, for example, mixed-methods designs, participation of target groups, and reflective loops within the research team. PMID- 29172697 TI - What are dementia champions and why do we need them? PMID- 29172695 TI - Maternal alcohol consumption and offspring DNA methylation: findings from six general population-based birth cohorts. AB - AIM: Alcohol consumption during pregnancy is sometimes associated with adverse outcomes in offspring, potentially mediated by epigenetic modifications. We aimed to investigate genome-wide DNA methylation in cord blood of newborns exposed to alcohol in utero. MATERIALS & METHODS: We meta-analyzed information from six population-based birth cohorts within the Pregnancy and Childhood Epigenetics consortium. RESULTS: We found no strong evidence of association at either individual CpGs or across larger regions of the genome. CONCLUSION: Our findings suggest no association between maternal alcohol consumption and offspring cord blood DNA methylation. This is in stark contrast to the multiple strong associations previous studies have found for maternal smoking, which is similarly socially patterned. However, it is possible that a combination of a larger sample size, higher doses, different timings of exposure, exploration of a different tissue and a more global assessment of genomic DNA methylation might show evidence of association. PMID- 29172698 TI - Regulation of UGT1A expression by miR-298 in human livers from the Han Chinese population and in human cell lines. AB - AIM: This study aimed to investigate the role of miRNAs in UGT1A regulation. MATERIALS & METHODS: Based on bioinformatic prediction results, luciferase reporter assay and cell-transfection experiments were performed to study effects of miR-298 on UGT1A expression. Correlation study was conducted in human livers. RESULTS: miR-298 overexpression reduced mRNA level of UGT1A1 and UGT1A4 in HepG2 and LS174T cells, and that of UGT1A3 and UGT1A9 in LS174T cells. miR-298 repression increased mRNA level of UGT1A4 in HepG2 and LS174T cells, and that of UGT1A1 and UGT1A3 in LS174T cells. Inverse correlations between miR-298, as well as miR-491-3p, and UGT1A3 and 1A4 mRNA levels were observed in livers. CONCLUSION: The study demonstrates that miR-298 and miR-491-3p downregulates UGT1A expression. PMID- 29172699 TI - Antimalarial and cytotoxic activities of pregnene-type steroidal alkaloids from Holarrhena pubescens roots. AB - The phytochemical investigation of an alkaloidal extract of Holarrhena pubescens roots led to the isolation and identification of a new pregnene-type alkaloid, mokluangin D (1), together with nine known steroidal alkaloids (2-10). The structure of the new metabolite was determined on the basis of spectroscopic analyses including 1D- and 2D-NMR spectroscopy and mass spectrometry. Compounds 3 and 4 showed potent antimalarial activity against Plasmodium falciparum K1 stain with IC50 values of 1.2 and 2.0 MUM, respectively, and showed weak cytotoxic activity against the NCI-H187 cell line with IC50 values of 27.7 and 30.6 MUM, respectively. The substituent groups at C-3 and the carbonyl group at C-18 are important for the activity against the P. falciparum K1 stain. PMID- 29172700 TI - A systematic review of acculturation, obesity and health behaviours among migrants to high-income countries. AB - Objective There is extensive evidence for weight gain among people migrating from low/middle-income to high-income countries, which may be due, in part, to acculturation factors. This review aimed to identify associations between acculturation and body weight among immigrants to high-income countries and identify if studies accounted for the role played by health behaviours. Methods A systematic literature search using keywords was performed with three databases (Medline, PsychINFO and EMBASE). The 35 studies were included that utilised quantitative methodology and presented empirical findings focused on acculturation and body weight among adult immigrants. Findings There was evidence presented across multiple studies for an association between acculturation (measured with standard measures or as duration of stay) and obesity. Most studies were cross sectional, which did not allow the exploration of drivers of change in health behaviours and weight gain. Conclusion This is the first review to examine associations between acculturation and body weight among migrants utilising both acculturation scales and proxy measures of acculturation and to examine the role of health behaviours. Evidence from this review suggests that health interventions should target first generation migrants to promote retention of their original healthy behaviours. Recent migrant groups report healthier behaviours than comparative host country populations, and therefore interventions should be promoted at the initial stages following migration to avoid uptake of unhealthy behaviours. PMID- 29172701 TI - The protection of unrepresented patients in emergency care research. AB - In emergency care research, it may be the case that neither informed consent nor surrogate consent is possible. In order to nonetheless allow for such research, codes and regulations of research ethics have increasingly incorporated provisions regarding this specific situation. The protection that those provisions offer need to be better understood. This article addresses in what ways they protect individuals, and especially the extent to which the suggested protection compensates for the loss of surrogate consent. The Declaration of Helsinki, the Additional Protocol to the Convention on Human Rights and Biomedicine, and the EU Clinical Trials Regulation serve as the main illustrations. PMID- 29172702 TI - Using Panel Vendors for Recruitment Into a Web-Based Family Prevention Program: Methodological Considerations. AB - Use of online panel vendors in research has grown over the past decade. Panel vendors are organizations that recruit participants into a panel to take part in web-based surveys and match panelists to a target audience for data collection. We used two panel vendors to recruit families ( N = 411) with a 16- to 17-year old teen to participate in a randomized control trial (RCT) of an online family based program to prevent underage drinking and risky sexual behaviors. Our article addresses the following research questions: (1) How well do panel vendors provide a sample of families who meet our inclusion criteria to participate in a RCT? (2) How well do panel vendors provide a sample of families who reflect the characteristics of the general population? and (3) Does the choice of vendor influence the characteristics of families that we engage in research? Despite the screening techniques used by the panel vendors to identify families who met our inclusion criteria, 23.8% were found ineligible when research staff verified their eligibility by direct telephone contact. Compared to the general U.S. population, our sample had more Whites and more families with higher education levels. Finally, across the two panel vendors, there were no significant differences in the characteristics of families, except for mean age. The online environment provides opportunities for new methods to recruit participants in research studies. However, innovative recruitment methods need careful study to ensure the quality of their samples. PMID- 29172703 TI - Quantitative EEG Parameters for Prediction of Outcome in Severe Traumatic Brain Injury: Development Study. AB - Monitoring of quantitative EEG (QEEG) parameters in the intensive care unit (ICU) can aid in the treatment of traumatic brain injury (TBI) patients by complementing visual EEG review done by an expert. We performed an explorative study investigating the prognostic value of 59 QEEG parameters in predicting the outcome of patients with severe TBI. Continuous EEG recordings were done on 28 patients with severe TBI in the ICU of Turku University Hospital. We computed a set of QEEG parameters for each patient, and correlated these to patient outcome, measured by dichotomized Glasgow Outcome Scale (GOS) at a follow-up visit between 6 and 12 months, using area under receiver operating characteristic curve (AUC) as a nonlinear correlation measure. For 17 of the 59 QEEG parameters (28.8%), the AUC differed significantly from 0.5, most of these parameters measured EEG power or variability. The best QEEG parameters for outcome prediction were alpha power (AUC = 0.87, P < .01) and variability of the relative fast theta power (AUC = 0.84, P < .01). The results of this study indicate that QEEG parameters provide useful information for predicting outcome in severe TBI. Novel QEEG parameters with potential in outcome prediction were found, the prognostic value of these parameters should be confirmed in later studies. The results also provide further evidence of the usefulness of parameters studied in preexisting studies. PMID- 29172705 TI - Expression of iron-related proteins in feline and canine mammary gland reveals unexpected accumulation of iron. AB - Dysregulation of cellular iron homeostasis in human breast cancer is reflected by the altered expression of regulatory proteins. The expressions of iron-related proteins in the mammary glands of cats and dogs have not been assessed. We evaluated the expressions of ferritin, ferroportin, hepcidin and transferrin receptor 1 in benign and malignant mammary gland lesions in cats and dogs. Iron deposition was detected using Perls' Prussian blue staining. We found no major differences in the expression of iron-related proteins between benign and malignant mammary gland lesions in either cats or dogs; however, these species exhibited accumulation of iron in benign lesions. Our findings provide an explanation for the absence of higher iron requirements by tumor cells in these animals. Further investigation of local iron homeostasis in cats and dogs and differences in their physiology compared to human breast cancer is required. PMID- 29172706 TI - Methylation changes and pathways affected in preterm birth: a role for SLC6A3 in neurodevelopment. AB - AIM: To analyze whether preterm newborns show differences in methylation patterns in comparison to full-term newborns in white blood cells. PATIENTS & METHODS: Anthropometrical, biochemical features and methylation levels of preterm newborns (n = 24) and full-term newborns (n = 22) recruited in La Paz University Hospital (Spain) were assessed at 12 months of gestational age, whereas Bayley Scale of Infant Development was evaluated at 24/36 months. RESULTS: From all the statistically significant CpGs, methylation levels of cg00997378 (SLC6A3 gene) showed the highest differences (p < 0.0001), being associated with prematurity risk factors. CONCLUSION: SLC6A3 methylation, previously related to attention deficit/hyperactivity disorder, neuronal function and behavior, might be a potential epigenetic biomarker with value in the early diagnosis and management of neurodevelopmental diseases in newborns. PMID- 29172707 TI - Growth kinetics and diosgenin estimation from callus cultures of Costus speciosus (Koen. ex. Retz.). AB - The present investigation reports the growth kinetics and diosgenin accumulation in callus cultures of Costus speciosus. Effect of explants, media and plant growth regulators was evaluated with respect to callus induction and growth. Out of the two explants viz pseudostem and seed, pseudostem showed maximum callus induction frequency of 90% on MS medium. The fresh weight of callus was maximum (9-folds) on 28th day on 1.0 mg/L picloram containing medium. The callus obtained was white compact hard (WCH). For growth kinetics study pseudostem derived callus was transferred on different media supplemented with 1.0 mg/L picloram. All phases of growth were seen in callus inoculated on all the three media except the absence of stationary phase on MS and SH media. MS medium proved to be the best for maximum biomass accumulation (9-fold) on 28th day of culture and callus in post-exponential phase showed maximum diosgenin accumulation (33 ppm).

AB - AIMS: The aim of the present study was to compare the efficacy of the commercial Xpert Mycobacterium tuberculosis/rifampin (MTB/RIF) test for evaluating different types of spinal tuberculosis (TB) tissue specimens. METHODS: Pus, granulation tissue, and caseous necrotic tissue specimens from 223 patients who were diagnosed with spinal TB and who underwent curettage were collected for bacterial culture and the Xpert MTB/RIF assay to calculate the positive rate. Bacterial culture and phenotypic drug sensitivity testing (pDST) were adopted as the gold standards to calculate the sensitivity and specificity of the Xpert bacterial detection and drug resistance (DR) test. RESULTS: The positive rate (68.61% +/- 7.35%) from the Xpert MTB/RIF assays of spinal TB patients' tissue specimens was higher compared with bacterial culture (44.39% +/- 6.51%, Z = 5.1642, p < 0.01), and the positive rates from Xpert MTB/RIF assays on the three types of specimens were all higher than those of bacterial culture, with statistically significant results for pus and granulation tissue specimens. The positive rates for pus using the two bacteriological tests were higher than those for granulation tissue but were not statistically significant. However, the positive rates obtained from granulation tissue were statistically significantly higher than those obtained from caseous necrotic tissue. With bacterial culture and pDST as the gold standards, the sensitivity of Xpert MTB/RIF assays for MTB was 96.97%, while the sensitivity and specificity of the DR test also remained relatively high. CONCLUSION: For efficient and accurate diagnosis of spinal TB and DR and timely provision of effective treatment, multiple specimens, especially the pus of spinal TB patients, should be collected for Xpert MTB/RIF assays.

AB - AIMS: Curcumin can suppress human prostate cancer (HuPCa) cell proliferation and invasion. However, it is not known whether curcumin can inhibit HuPCa stem cell (HuPCaSC) proliferation and invasion. MATERIALS AND METHODS: We used methyl thiazolyl tetrazolium and Transwell assays to examine the proliferation and invasion of the HuPCaSC lines DU145 and 22Rv1 following curcumin or dimethyl sulfoxide (control) treatment. The microRNA (miRNA) expression levels in the DLK1 DIO3 imprinted genomic region in the cells and in tumor tissues from patients with PCa were examined using microarray and quantitative PCR. RESULTS: The median inhibitory concentration of curcumin for HuPCa cells significantly inhibited HuPCaSC proliferation and invasion in vitro. The miR-770-5p and miR-1247 expression levels in the DLK1-DIO3 imprinted gene cluster were significantly different between the curcumin-treated and control HuPCaSCs. Overexpression of these positive miRNAs significantly increased the inhibition rates of miR-770-5p- and miR-1247-transfected HuPCaSCs compared to the control miR-Mut-transfected HuPCaSCs. Lastly, low-tumor grade PCa tissues had higher miR-770-5p and miR-1247 expression levels than high-grade tumor tissues. CONCLUSIONS: Curcumin can suppress HuPCaSC proliferation and invasion in vitro by modulating specific miRNAs in the DLK1-DIO3 imprinted gene cluster. PMID- 29172710 TI - Low rates of post-craniotomy surgical site infections in a developing country: surgical technique and results. AB - INTRODUCTION: Although neurosurgical surgical site infections (SSI) exert a devastating price on the postoperative course of patients in the developing countries, literature is sparse on the subject from these regions. METHODS: This study is an audit of post-craniotomy SSI in a sub-Sahara African academic neurosurgical practice. It is a retrospective descriptive analysis of neurosurgical SSI in a 7-year consecutive cohort of patients who survived more than 5 days following major cranial surgery. Our general neurosurgical operative goal is to keep the incidence of SSI as close to the global range as possible by, amongst other measures, enforcing strict compliance with appropriate operative room practice. RESULTS: There were 211 craniotomies/craniectomies; 194 primary and 17 redo procedures. Male patients constituted 65%. The mean age was 32.2 (Standard Deviation +/- 17.2) years. The procedures were emergencies in 42.7% and urgent or elective in the rest. They were surgery for trauma in 46.9% and for tumour resections in 44.1%. The median duration of surgery was 3 hours (range 1 8.5 hours). Mortality was 4.3%. Functional outcome was assessed using a dichotomized Glasgow Outcome Scale and was good in 90.5%. Surgical site infections, mainly by Gram negative coliforms, occurred in 9 cases, 4.3%, leading to worse in-hospital outcome of 56% (p < .001) in those affected. Patients with a poorer pre-operative Karnofsky performance status had a higher infection rate (7.5%), than those with better clinical performance index, (2.3%). This difference was not significant (p = .09, unadjusted OR 3.46, 95% Confidence Interval 0.84-14.24). CONCLUSION: Post-craniotomy SSI rates comparable to those in more advanced practice areas is achievable in developing countries. PMID- 29172711 TI - Decision-making in children in the Hungry Donkey Test: A behavioral analysis. AB - This study analyzed choice behavior in the Hungry Donkey Task, with a focus on learning trajectories and the stability of preference, in 100 children of different ages (8-9, 10-11, 12-13, 14-15, and 16-17 years old). The results indicated that (a) learning occurred as the task progressed, (b) early adolescents performed poorly during the task, and (c) most of the participants did not reach the stability criterion during the task. The present study suggests that decision-making in children and adolescents varies with age, and that the inclusion of an operant-based approach (e.g., the use of stability criterion) may improve methods for evaluating decision-making in children. PMID- 29172712 TI - Decompressive craniectomy in aneurysmal subarachnoid haemorrhage for hematoma or oedema versus secondary infarction. AB - PURPOSE: Decompressive craniectomy (DC) has been proposed as lifesaving treatment in aneurysmal subarachnoid haemorrhage (aSAH) patients with elevated intracranial pressure (ICP). However, data is sparse and controversy exists whether the underlying cause of elevated ICP influences neurological outcome. The purpose of this study is to clarify the role of the underlying cause of elevated ICP on outcome after DC. MATERIALS AND METHODS: We retrospectively studied the one-year neurological outcome in a single-centre cohort to identify predictors of favourable (Glasgow Outcome Scale (GOS) 4-5) and unfavourable (GOS 1-3) outcome. Additionally, available individual patient data in the literature was reviewed with a special emphasis on the underlying reason for DC. RESULTS: From 2006-2015, 53 consecutive aSAH patients underwent DC. Nine (17%) achieved favourable, 44 (83%) unfavourable outcome (31 patients died). One fourth of the patients undergoing DC for hematoma or (hematoma-related) oedema survived favourably (increasing to 46% for patients aged <51 years), versus none of the patients undergoing DC for secondary infarction. Analysis of individual data of 105 literature patients showed a similar trend, although overall outcome was much better: half of the patients undergoing DC for hematoma/oedema regained independence, versus less than one-fourth of patients undergoing DC for secondary infarction. CONCLUSIONS: DC in aSAH patients is associated with high rates of unfavourable outcome and mortality, but hematoma or oedema as underlying reason for DC is associated with better outcome profiles compared to secondary infarction. Future observational cohort studies are needed to further explore the different outcome profiles among subpopulations of aSAH patients requiring DC. PMID- 29172714 TI - Heroes or Health Victims?: Exploring How the Elite Media Frames Veterans on Veterans Day. AB - We examine the frames the elite news media uses to portray veterans on and surrounding Veterans Day 2012, 2013, 2014, and 2015. We use mental health illness and media framing literature to explore how, why, and to what extent Veterans Day news coverage uses different media frames across the four consecutive years. We compiled a Media Coverage Corpora for each year, which contains the quotes and paraphrased remarks used in all veterans news stories for that year. In our primary study, we applied the meaning extraction method (MEM) to extract emergent media frames for Veterans Day 2014 and compiled a word frequency list, which captures the words most commonly used within the corpora. In post hoc analyses, we collected news stories and compiled word frequency lists for Veterans Day 2012, 2013, and 2015. Our findings reveal dissenting frames across 2012, 2013, and 2014 Veterans Day media coverage. Word frequency results suggest the 2012 and 2013 media frames largely celebrate Veterans as heroes, but the 2014 coverage depicts veterans as victimized by their wartime experiences. Furthermore, our results demonstrate how the prevailing 2015 media frames could be a reaction to 2014 frames that portrayed veterans as health victims. We consider the ramifications of this binary portrayal of veterans as either health victims or heroes and discuss the implications of these dueling frames for veterans' access to healthcare resources. PMID- 29172713 TI - Activation of the molecular and functional effects of Nrf2 against chronic iron oxide nanorod overload-induced cardiotoxicity. AB - Reactive oxygen species have a significant role in the pathogenesis of iron oxide nanorod (IONR) overload-induced organ toxicity in some organs such as the lungs. Green tea induces upregulation of phase II antioxidant enzymes that are transcriptionally organized by the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) that when activated antagonize the oxidative stress induced by IONR overload that causes cardiotoxicity. The aim of the present study was to determine whether treatment of cardiotoxicity with iron chelators (deferiprone (DFP) or deferoxamine (DFO)) alone or in combination with phytochemical activation of Nrf2 (green tea) can protect cardiomyocytes from IONR overload induced cardiotoxicity. One hundred five rats were distributed into seven groups: two control groups (non-IONR-overloaded and IONR-overloaded) and five IONR overloaded groups such as a green tea group, DFP group, DFP combined with green tea group, DFO group, and DFO combined with green tea. Blood samples and cardiac tissues were obtained for estimation of total iron-binding capacity, ratio of myocardial 8-hydroxy-2'-deoxyguanosine/myocardial 2-deoxyguanosine, thiobarbituric acid reactive substances, glutathione (GSH) contents, and histopathological examination. The results showed mild histopathological changes in the heart and a significant decrease in all biochemical parameters, except for myocardial GSH, in the DFP group. The addition of green tea improved the biochemical and histopathological results compared with chelators alone. PMID- 29172715 TI - The rationale and design of reduction of uncontrolled hypertension by Remote Monitoring and Telemedicine (REMOTE) study. AB - PURPOSE: Although self-measurement of home blood pressure (HBP) is common in Japan and HBP telemonitoring via the Internet is possible, whether telemonitoring improves HBP control better than conventional practice remains unclear. Furthermore, hypertension care with online communication using telemonitored HBP is feasible, whereas the efficacy and safety of such telemedicine have not been established. We aim to compare traditional care, care with office visits using HBP telemonitoring, and antihypertensive telemedicine based on HBP telemonitoring. METHODS AND DESIGN: In total, 444 patients with uncontrolled hypertension will be recruited and randomly assigned to three groups: (1) control: usual care with office visits and HBP self-report, (2) telemonitoring: weekly assessment of transmitted HBP by physicians and treatment adjustment upon office visits, or (3) telemedicine: online communication instead of office visits to adjust medication using telemonitored HBP. Primary outcome is the time to control of HBP, and secondary outcomes include achieved HBP levels, adherence, treatment intensity, adverse events, patient satisfaction and cost-effectiveness. DISCUSSION: Hypertension care with telemonitoring and telemedicine are expected to require shorter time to achieve HBP control compared to usual care. Combining HBP telemonitoring with telemedicine may lower the hurdles for starting and persisting to hypertension treatment and eventually reduce cardiovascular events. PMID- 29172716 TI - Aircraft Noise Exposure and Subjective Sleep Quality: The Results of the DEBATS Study in France. AB - BACKGROUND: Exposure to aircraft noise has been shown to have adverse effects on health, particularly on sleep. Exposure to nighttime aircraft noise clearly affects sleep architecture, as well as subjective sleep quality. OBJECTIVES: This study aimed to investigate the relationship between aircraft noise exposure and subjective sleep quality in the population living near airports in France. METHODS: A total of 1,244 individuals older than 18 and living near three French airports (Paris-Charles de Gaulle, Lyon-Saint-Exupery, and Toulouse-Blagnac) were randomly selected to participate in the study. Information on sleep as well as health, socioeconomic, and lifestyle factors was collected by means of a face-to face questionnaire performed at their place of residence by an interviewer. For each participant, aircraft noise exposure was estimated at home using noise maps. Logistic regression models were used with adjustment for potential confounders. RESULTS: Aircraft noise exposure was significantly associated with a short total sleep time (TST; <= 6 h) and with the feeling of tiredness while awakening in the morning. An increase of 10 dB(A) in aircraft noise level at night was associated with an OR of 1.63 (95% CI: 1.15-2.32) for a short TST and an OR of 1.23 (95% CI: 1.00-1.54) for the feeling of tiredness while awakening in the morning. CONCLUSIONS: These findings contribute to the overall evidence suggesting that aircraft noise exposure at nighttime may decrease the subjective amount and quality of sleep. PMID- 29172717 TI - Comparative effectiveness of the biosimilar CT-P13. AB - The first biosimilar infliximab, CT-P13 (infliximab-dyyb) has been used for the treatment of inflammatory diseases for 4 years. CT-P13 has highly similar efficacy and safety profiles with a lower price than the originator infliximab and has been approved in 81 countries. Despite approval for clinical use, some knowledge gaps still limit the widespread and pertinent use of biosimilar CT-P13. One of the most important factors for proper utilization of CT-P13 for the treatment of immune-mediated inflammatory diseases is confidence in CT-P13, which could be enhanced by scientific evidence supporting the biosimilarity of CT-P13. Overall, five randomized controlled studies have been performed. For the other extrapolated indications, many observational induction and switching studies also support the utility of CT-P13 in the treatment of inflammatory diseases. Here, we review profiles of CT-P13 including physicochemical properties, clinical efficacy and safety data in all indications and current status. PMID- 29172718 TI - Lack of effects of myo-inositol on metabolism of primary rat adipocytes. AB - Myo-inositol is a ubiquitous cyclitol, has an important regulatory role, and its intracellular depletion is associated with pathological changes. Effects of myo inositol on adipose tissue are poorly elucidated. In this report, short-term influence of 20, 100, and 500 uM myo-inositol on metabolism of the isolated rat adipocytes was studied. Cells were incubated for 90 min with glucose and insulin with or without myo-inositol and glucose conversion to lipids and lactate release were measured. Moreover, effects of myo-inositol on lipolysis and on the antilipolytic action of insulin were also studied. It was demonstrated that lipogenesis and lactate release were unchanged by myo-inositol. Moreover, lipolytic response to epinephrine and dibutyryl-cAMP was also unchanged. Myo inositol was also found to be without influence on the antilipolytic action of insulin. Results of this study show that metabolism of the isolated rat adipocytes is not affected by short-term exposure of these cells to myo-inositol. PMID- 29172719 TI - T-cell receptor-mediated characteristic signaling pathway of peripheral blood T cells in dermatomyositis and polymyositis. AB - The characteristics of T cell expression in peripheral blood have been previously described in dermatomyositis (DM) and polymyositis (PM); however, their intracellular signaling profiles remain unknown. The purpose of this study was to investigate the T-cell receptor (TCR)-mediated intracellular signaling in peripheral blood T cells in DM and PM. Peripheral blood T cells from 86 patients with DM (n = 57) and PM (n = 29) were used for experimental investigations. T cell subtypes and TCR-induced phosphorylated zeta-chain-associated protein kinase 70 (pZAP70) were analyzed by flow cytometry. Signal transducer and activator of transcription (STAT) and some inhibitory factors in T cells with TCR stimulation were also investigated by quantitative real-time polymerase chain reaction. T cell counts were significantly lower in DM than in PM. In addition, STAT, forkhead box transcription factor (FoxP3), and pZAP70 expression in CD4+ T cells was suppressed in DM, whereas STAT and pZAP70 expression in CD8+ T cells was induced in PM. Especially in DM, a positive correlation between CD4+ T cell counts and STAT expression was detected. In addition, low CD4+ T cell counts as well as reduced STAT expression were prominent in patients with interstitial lung disease. STAT and pZAP70 expression significantly improved after clinical remission in both DM and PM, although expression of FoxP3 remained suppressed. Besides, upregulation of suppressor of cytokine signaling-3 (SOCS3) and downregulation of interleukin 6 signal transducer (IL6ST) in CD4+ T cells were observed in both DM and PM; however, no significant improvements were detected after clinical remission. The results of the present study suggested that TCR mediated signaling may be a key pathway to determine the different characteristics of peripheral blood T cells between DM and PM. In addition, upregulation of SOCS3 and downregulation of IL6ST and FoxP3 in CD4+ T cells may cause an imbalance in intracellular signaling, especially in DM, suggesting that further studies are required to identify how the impaired signaling contributes to the development of the disease. PMID- 29172720 TI - Preliminary study on current perceptions and usage of training equipment by horse enthusiasts in Canada. AB - Training practices may impose restrictions on the equine behavioral repertoire through the use of training equipment. Presently, the prevalence of the use of training equipment in Canada is unknown. Through an online survey for horse enthusiasts (n = 654), this study evaluated the prevalence and predominant uses of whips, spurs, and head-control equipment by enthusiasts with direct contact with horses compared to perceptions held by enthusiasts with no direct horse contact using chi-squared analyses. Respondents primarily reported using whips and spurs to augment rider or trainer cues and reported using head-control equipment mainly for lunging purposes. The perceived frequency of spurs and head control equipment use during riding or training by nonactive horse enthusiasts was significantly greater than reported usage by riders and trainers (p < .05). The results potentially indicate a lack of understanding and miscommunication of training equipment use by riders and trainers. The frequent reporting of training equipment for the purpose of augmenting rider cues may imply misinterpretation of the correct application of learning theory. These preliminary results warrant further investigation of equipment use within the horse industry. PMID- 29172721 TI - Anogenital distance and variability in semen parameters. AB - : The purpose of this study was to analyze whether the anogenital distance (AGD) was associated with variability in semen parameters. Semen parameters analyzed following the WHO guidelines and sperm DNA fragmentation were evaluated in 160 semen samples obtained over a period of a year from 16 healthy male volunteers. Two types of AGD measurements from the anus to the rear base of the scrotum (AGDAS) and to the cephalic insertion of the penis (AGDAP) were taken in each individual. The association between AGDs and semen parameters were studied using three statistical tools: a) general coefficient of variation (CV) and intra individual coefficient of variation (CVi), b) general linear models for repeated measures, and c) mixed model fixed effects panel data. Men with shortened AGDAP have significantly greater intra-individual variability in sperm concentration, total sperm count, and normal sperm morphology. Conversely, greater total sperm motility was observed in men with long AGDAS. Shortened AGDAS was associated with less intra-individual variability of total sperm motility (progressive and non progressive). AGD measurements were associated with the variability in semen parameters. AGD may be useful to determine intra-individual variability in semen parameters. ABBREVIATIONS: AGD: anogenital distance; AGDAP: anogenital distance from the anus to the cephalic insertion of the penis; AGDAS: anogenital distance from the anus to the rear base of the scrotum; AIC: Akaike information criteria; BMI: body mass index; CV: general coefficient of variation; CVi: intra-individual coefficient of variation; GLM: generalized linear model; PR+NP: total sperm motility. PMID- 29172722 TI - Effect of switch trimming on udder and teat hygiene of dairy cows. AB - The study objective was to determine the effects of trimming the switch of dairy cows on teat-end bacterial counts and udder hygiene scores. Cows (n = 102) were blocked by days in milk, milk production, and parity and then assigned to (a) treatment (trimming of their tail switch using a commercially available trimmer), or (b) control (unaltered tails). Udder hygiene was recorded for cows on Days 0 (initiation of treatment), 32, and 64. A subset of cows (n = 21) was used to assess Streptococci and coliform bacterial populations on teat ends. Samples were collected by swabbing the left front teat end before milking on Days 0, 32, and 64 and were cultured within 24 hr of sampling. The GLIMMIX and PROC Frequency (SAS Version 9.3) were used to analyze data. There were no treatment effects of switch trimming on hygiene scores or bacterial counts. These findings suggest that udder hygiene may not be driven by tail status. Environmental and management factors, such as cleanliness, stall bedding, and stall design, may be more important contributing factors in maintaining udder health. PMID- 29172723 TI - Subjective Sleep Related to Post Traumatic Stress Disorder Symptoms among Trauma Exposed Men and Women. AB - OBJECTIVE/BACKGROUND: Sleep difficulty is both a common symptom of posttraumatic stress disorder (PTSD) and a risk factor for the development and maintenance of PTSD symptomatology. Gender differences in sleep following trauma exposure have been posited to contribute to the increased risk for the development of PTSD among women, but the persistence and long-term contributions of these potential differences to the maintenance and severity of PTSD symptoms is unclear. PARTICIPANTS: Men and women reporting a history of trauma exposure (n = 112, 63% female) participated in this study. METHODS: Subjective sleep complaints and PTSD symptom severity were assessed using well-validated measures (Pittsburgh Sleep Quality Index, PTSD Symptom Checklist). Multivariable regression models (full sample and gender-stratified) were used to predict PTSD symptom severity from global, subscale, and individual item sleep parameters, adjusted for gender, age, race/ethnicity, education, and body mass index. RESULTS: In the full sample, traditional measures of sleep quality and sleep disturbance were associated with PTSD symptom severity. Difficulty falling asleep, poor sleep quality, and sleep disturbance from a variety of sources were related to higher PTSD symptom severity in men, while self-reported sleep disturbance related to nightmares and emotional regulation were associated with PTSD symptom severity among women. CONCLUSIONS: These findings add to the limited literature on gender-specific risk factors related to sleep and PTSD, and may inform intervention development and implementation related to PTSD severity among vulnerable adults. PMID- 29172724 TI - Distribution and Diversity of Ocular Microbial Communities in Diabetic Patients Compared with Healthy Subjects. AB - PURPOSE: The aim of this study was to identify differences in the major (core vs. variable) microbial genera of human subjects with and without diabetes. METHODS: Bacterial 16S rRNA genes obtained from conjunctival swabs of 19 healthy subjects and 30 diabetic patients were sequenced using the Illumina MiSeq platform, and the sequencing data were analyzed using QIIME 1.9.1. To elucidate the microbial diversity in the ocular surface (OS), test programs from various bioinformatics domains were used. RESULTS: Diversity index and rarefaction analysis showed that the microbial community of the diabetic patients was more diverse than that of the healthy subjects. Proteobacteria, Firmicutes, Actinobacteria, Cyanobacteria and Bacteroidetes were the dominant taxa present in the OS, and there was a significant difference in the relative abundance of the bacterial phyla between the diabetic patients and control subjects. Proteobacteria were more abundant in the diabetic group, whereas Firmicutes was more abundant in the control group. Analysis of bacterial taxa at the genus level showed that the core microbiome of diabetic patients comprised Acinetobacter, Burkholderia, Sphingomonas, and Ralstonia, whereas that of the controls comprised Bradyrhizobiaceae, Staphylococcus, Corynebacterium, Pseudomonas, Novosphingobium, Neisseriaceae, and Acinetobacter. CONCLUSIONS: There was a significant difference in the microbial community composition between diabetic patients and healthy subjects. A high abundance of Acinetobacter in the OS of diabetic patients may arise from the unique characteristics of the OS compared with those of other organ surfaces. PMID- 29172725 TI - Objective cognitive impairment and subjective cognitive problems in veterans initiating psychotherapy for posttraumatic stress disorder: An exploratory study. AB - The prevalence of cognitive impairment in Veterans initiating an evidence-based psychotherapy (EBP) for posttraumatic stress disorder (PTSD) is not yet established and has implications for service delivery. Our objectives were to (1) describe the type, severity, and prevalence of objective cognitive impairment and subjective cognitive problems experienced by Veterans at the time they began an EBP for PTSD and (2) determine whether assessments of objective cognitive impairment and subjective cognitive problems agree. We conducted objective and subjective (self-report) cognitive assessments in a sample of 38 Veterans initiating EBP for PTSD at one Veterans Affairs Medical Center. Thirty Veterans produced valid assessments. Almost half (14/30) of the participants demonstrated objective impairment in one or more cognitive domains, primarily in the areas of learning, memory, and processing speed. Almost all (29/30) participants endorsed moderate or greater cognitive problems on at least one self-report measure. After adjustment for multiple comparisons, there were no significant correlations between objective and subjective assessments. Objective cognitive impairment and subjective cognitive problems are common in Veterans beginning an EBP for PTSD. Longitudinal research on a larger sample is warranted to better understand relationships among subjective cognitive problems, objective cognitive impairment, and PTSD treatment participation and outcomes. PMID- 29172726 TI - Association between serum osteocalcin level and blood pressure in a Chinese population. AB - PURPOSE: This observational study investigated the association between serum osteocalcin level and blood pressure in a Chinese population. MATERIALS AND METHODS: A total of 2241 subjects (909 men and 1,332 women; age, 24-78 years) from Shanghai communities were recruited. Subjects were divided into non hypertensive and hypertensive groups according to diagnosis of hypertension based on the 1999 World Health Organization-International Society of Hypertension Guidelines. Serum osteocalcin levels were measured using an electrochemiluminescence immunoassay. RESULTS: Men in the hypertensive group showed lower serum osteocalcin level compared with those in the non-hypertensive group, [16.37 (13.34-20.11) ng/mL versus 17.01 (14.23-20.79) ng/mL, p = .039]. No difference in serum osteocalcin level was found between the two groups of women (p = .675). An inverse association was observed between serum osteocalcin level and systolic blood pressure (SBP) in men (p = .004), but serum osteocalcin level was not associated with diastolic blood pressure (DBP) in men (p = .472). No associations were detected between serum osteocalcin level and SBP or DBP in women (SBP: p = .108; DBP: p = .575). A multiple stepwise regression analysis showed an inverse association between serum osteocalcin level and SBP in men after adjusting for age, smoking status, family history of hypertension, and lipid and C-reactive protein levels (standardized beta = -0.074, p = .023), but the association disappeared after adjustment for body mass index, waist circumference, blood glucose, and homeostasis model assessment of insulin resistance (p = .327). CONCLUSIONS: Serum osteocalcin level was not independently associated with blood pressure in a Chinese population. PMID- 29172727 TI - Objective Versus Self-Reported Sleep Quality at High Altitude. AB - : Anderson, Paul J., Christina M. Wood-Wentz, Kent R. Bailey, and Bruce D. Johnson. Objective versus self-reported sleep quality at high altitude. High Alt Med Biol. 16:000-000, 2017. BACKGROUND: Previous studies have found little relationship between polysomnography and a diagnosis of acute mountain sickness (AMS) using the Lake Louise Symptom Questionnaire (LLSQ). The correlation between sleep question responses on the LLSQ and polysomnography results has not been explored. We compared LLSQ sleep responses and polysomnography data from our previous study of workers rapidly transported to the South Pole. METHODS: Sixty three subjects completed a 3-hour flight from sea level to the South Pole (3200 m, 9800 ft). Participants completed limited overnight polysomnography on their first night and completed LLSQ upon awakening. We compared polysomnography results at the South Pole with sleep question responses on the LLSQ to assess their degree of correspondence. RESULTS: Twenty-two (30%) individuals reported no sleep problems whereas 20 (32%) reported some problems and 20 (33%) individuals reported poor sleep and 1 reported no sleep (n = 1). Median sleep efficiency was (94%) among response groups and mean overnight oxygen saturation was 81%. Median apnea hypopnea index (AHI; events/hour) was 10.2 in those who reported no problems sleeping, 5.1 in those reporting some problems sleeping, and 13.7 in those who reported poor sleep. These differences were not statistically significant. CONCLUSION: Self-reported sleep quality varied but there were no associated significant differences in sleep efficiency, overnight oxygen saturation, nor AHI. Studies that explore the role of objective sleep quality in the development of AMS should remove the sleep question on the LLSQ from AMS scoring algorithms. PMID- 29172728 TI - Diurnal variation and reliability of the urine lactate concentration after maximal exercise. AB - The postexercise urine lactate concentration is a novel valid exercise biomarker, which has exhibited satisfactory reliability in the morning hours under controlled water intake. The aim of the present study was to investigate the diurnal variation of the postexercise urine lactate concentration and its reliability in the afternoon hours. Thirty-two healthy children (11 boys and 21 girls) and 23 adults (13 men and 10 women) participated in the study. All participants performed two identical sessions of eight 25 m bouts of maximal freestyle swimming executed every 2 min with passive recovery in between. These sessions were performed in the morning and afternoon and were separated by 3-4 days. Adults performed an additional afternoon session that was also separated by 3-4 days. All swimmers drank 500 mL of water before and another 500 mL after each test. Capillary blood and urine samples were collected before and after each test for lactate determination. Urine creatinine, urine density and body water content were also measured. The intraclass correlation coefficient was used as a reliability index between the morning and afternoon tests, as well as between the afternoon test and retest. Swimming performance and body water content exhibited excellent reliability in both children and adults. The postexercise blood lactate concentration did not show diurnal variation, showing a good reliability between the morning and afternoon tests, as well as high reliability between the afternoon test and retest. The postexercise urine density and lactate concentration were affected by time of day. However, when lactate was normalized to creatinine, it exhibited excellent reliability in children and good-to-high reliability in adults. The postexercise urine lactate concentration showed high reliability between the afternoon test and retest, independent of creatinine normalization. The postexercise blood and urine lactate concentrations were significantly correlated in all cases, attesting to the validity of urine lactate as an index of anaerobic metabolism. We conclude that urine lactate, after normalization to creatinine, could be used in training practice either in the morning or in the afternoon. Further research is needed to assess the applicability of this novel exercise biomarker. PMID- 29172729 TI - Association of insulin resistance and autonomic tone in patients with pregnancy induced hypertension. AB - Pregnancy-induced hypertension (PIH) remains the main cause of maternal and fatal mortality. Insulin resistance (IR) and autonomic nervous system (ANS) imbalance are two principal drivers of PIH development. Few previous researches investigated the association between IR and ANS imbalance in Chinese PIH patients. 120 pregnant women were enrolled in our study, sixty healthy pregnant women (control group), fourty one gestational hypertension (GH group) and nineteen preeclampsia patients (PE group). The homeostasis model assessment of IR (HOMA-IR) and markers of ANS (plasma biomarkers and heart rate variability (HRV) components) were collected. Body mass index (BMI), Ln(HOMA-IR), noradrenaline level, LnTP (total power), Ln SDNN (standard deviation of the normal-to-normal interval), LnLF (low frequency), LnLF/LnHF (low frequency/high frequency) were different in the GH and PE groups compared with the controls. Significant correlations were observed between Ln (HOMA-IR) and gestational duration (r = 0.237, P = 0.031), BMI(r = 0.314, P = 0.002), systolic blood pressure (r = 0.108, P = 0.016), noradrenaline (r = 0.451, P = 0.009), LnTP (r = -0.269, P = 0.015) and LnLF/HF (r = 0.183, P = 0.026) in those PIH patients. Furthermore, BMI, noradrenaline and LnTP were independent determinants of Ln(HOMA-IR) in PIH patients by multiple regression analysis. Our finding verified both IR and ANS imbalance were more severe in PIH patients than healthy pregnant women. Moreover, IR had a close association with ANS parameters in PIH patients, suggesting that they probably had contributory effects on the occurrence and development of PIH. We propose that these parameters could be added to the traditional indexes for individualized treatment of PIH patients in the future.

PMID- 29172730 TI - Renal sympathetic denervation lowers arterial pressure in canines with obesity induced hypertension by regulating GAD65 and AT1R expression in rostral ventrolateral medulla. AB - To explore the roles of glutamate acid decarboxylase 65 (GAD65) and angiotensin II type 1 receptor (AT1R) in the action of renal sympathetic denervation (RSD) on obesity-induced hypertension in canines. Thirty-two beagles were randomly divided into a hypertensive model (n = 22) and control (n = 10) groups. A hypertensive canine model was established by feeding a high-fat diet. Twenty hypertensive beagles were randomized equally to a sham-surgery and RSD-treated group receiving catheter-based radiofrequency RSD. Compared with the control group, the sham surgery group exhibited significant increases in blood pressure, serum angiotensin II level, rostral ventrolateral medulla (RVLM) glutamate level, and AT1R mRNA and protein expression and decreases in gamma-amino acid butyric acid (gamma-GABA) level and GAD65 mRNA and protein expression in the RVLM (all P < 0.05). Treatment with RSD significantly attenuated the above abnormal alterations (all P < 0.05). Linear correlation analysis revealed that angiotensin II level was positively correlated with glutamate level (r = 0.804) and inversely correlated with gamma-GABA level (r = -0.765). GAD65 protein expression was positively correlated with gamma-GABA level (r = 0.782). Catheter-based radiofrequency RSD can decrease blood pressure in obesity-induced hypertensive canines. The antihypertensive mechanism might be linked to upregulation of GAD65 and downregulation of AT1R in the RVLM. PMID- 29172732 TI - Effect of amlodipine, efonidipine, and trichlormethiazide on home blood pressure and upper-normal microalbuminuria assessed by casual spot urine test in essential hypertensive patients. AB - The aim of this study was to assess the effects of irbesartan alone and combined with amlodipine, efonidipine, or trichlormethiazide on blood pressure (BP) and urinary albumin (UA) excretion in hypertensive patients with microalbuminuria (30<=UA/creatinine (Cr) ratio [UACR] <300 mg/g Cr) and upper-normal microalbuminuria (10<=UACR<30 mg/g Cr). This randomized controlled trial enrolled 175 newly diagnosed and untreated hypertensive patients (home systolic blood pressure [SBP]>=135 mmHg; 10<=UACR<300 mg/g Cr of casual spot urine at the first visit to clinic). All patients were treated with irbesartan (week 0). Patients who failed to achieve home SBP <=125 mmHg on 8-week irbesartan monotherapy (nonresponders, n = 115) were randomized into three additional drug treatment groups: trichlormethiazide (n = 42), efonidipine (n = 39), or amlodipine (n = 34). Irbesartan monotherapy decreased home SBP and first morning urine samples (morning UACR) for 8 weeks (p < 0.0001). At 8 weeks after randomization, all three additional drugs decreased home SBP (p < 0.0002) and trichlormethiazide significantly decreased morning UACR (p = 0.03). Amlodipine decreased morning UACR in patients with microalbuminuria based on casual spot urine samples (p = 0.048). However, multivariate analysis showed that only higher home SBP and UACR at week 8, but not any additional treatments, were significantly associated with UACR reduction between week 8 and week 16. In conclusion, crucial points of the effects of combination therapy on UACR were basal UACR and SBP levels. The effect of trichlormethiazide or amlodipine treatment in combination with irbesartan treatment on microalbuminuria needs to be reexamined based on a larger sample size after considering basal UACR and SBP levels. PMID- 29172733 TI - Nocturnal blood pressure decline based on different time intervals and long-term cardiovascular risk: the Ohasama Study. AB - A diminished nocturnal decline in blood pressure (BP) represents a risk factor for cardiovascular disease. To define daytime and nighttime ambulatory BP, clock time-dependent methods are used when information on diary-based sleeping time is unavailable. We aimed to compare fixed-clock intervals with diary records to identify nocturnal BP declines as a predictor of long-term cardiovascular risk among the general population. Data were obtained from 1714 participants with no history of cardiovascular disease in Ohasama, Japan (mean age, 60.6 years; 64.9% women). We defined extreme dippers, dippers, non-dippers, and risers as nocturnal systolic BP decline >=20%, 10-19%. 0-9%, and <0%, respectively. Over a mean follow-up period of 17.0 years, 206 cardiovascular deaths occurred. Based on diary records, multivariable-adjusted hazard ratios (HRs) for cardiovascular death compared with dippers were 1.24 (95% confidence interval [CI], 0.82-1.87) in extreme dippers, 1.21 (0.87-1.69) in non-dippers, and the highest HR of 2.31 (1.47-3.62) was observed in risers. Using a standard fixed-clock interval (daytime 09:00-21:00; nighttime 01:00-06:00), a nighttime 2 h-early shifted fixed clock (daytime 09:00-21:00; nighttime 23:00-04:00), or a nighttime 2 h-late shifted fixed-clock (daytime 09:00-21:00; nighttime 03:00-08:00), the HR (95%CI) in risers compared with dippers was 1.57 (1.08-2.27), 2.02 (1.33-3.05), or 1.29 (0.86-1.92), respectively. Although use of diary records remains preferable, the standard and nighttime 2 h-early shifted fixed-clock intervals appear feasible for population-based studies. PMID- 29172734 TI - Correlation between clinic, cumulative, 24h-ambulatory systolic blood pressure, and chronic kidney damage in Chinese elderly. AB - The aim of this study was to investigate whether clinic, cumulative, and 24h ambulatory systolic blood pressure (SBP) was associated with chronic kidney damage, defind as estimated glomerular filtration rate (eGFR) <60 ml/(min.1.73 m2) and/or microalbuminuria >=30 mg/L, and, if so, which measurement of SBP is more associated with chronic kidney damage in Chinese elderly. A total of 1207 participants older than 60 years old were included in the final analysis. Clinical blood pressure, cumulative blood pressure exposure was calculated and ambulatory 24h blood pressure was assessed. Multiple logistic regression analysis showed that the clinic (p < .001), cumulative (p = .033), 24h average (p < .001), daytime (p = .001) and nighttime SBP (p = .001) were respectively associated with lower eGFR, and cumulative (p = .008), 24 average (p < .001), daytime (p < .001), and nighttime SBP (p < .001) were the risk factors of microalbuminuria. The degree of correlation were strongest between 24h average SBP and chronic kidney damage (odds ratio, 1.78; 95% confidence interval, 1.46-2.15; p < .001), clinic SBP and eGFR (odds ratio, 1.57; 95% confidence interval, 1.13-2.17; p = .007), nighttime SBP and microalbuminuria (odds ratio, 1.45; 95% confidence interval, 1.05-2.00; p = .024). The likelihood ratio test demonstrated that the introduction of 24h average SBP will improve the goodness of fit of the clinic SBP model(p < .05), while the introduction of cumulative SBP exposure has no such effect(p > .05). Cumulative SBP exposure seems inferior to other measurement in indentifying chronic kidney damage, including decreased GFR and microalbuminuria. PMID- 29172735 TI - Effects of Ganoderma, Rhodiola and grape seed extracts on the glucuronidation and oral bioavailability of resveratrol in rats. AB - Herb extracts were shown to inhibit the activity of UDP-glucuronosyltransferases (UGTs) in vitro. However, the actual in vivo effect of the inhibitory ability on oral bioavailability is yet verified. In this study, resveratrol (RES) was used as a model drug to study the effect of three Chinese herb extracts, Ganoderma, Rhodiola and grape seed, on the in vitro and in vivo inhibition of glucuronidation and the in vivo bioavailability of RES. Overall, although herb extracts might show inhibition on glucuronidation of RES in vitro and in vivo, the inhibition of glucuronidation did not necessarily mean to improve the in vivo bioavailability of RES. PMID- 29172736 TI - Role of Glial Cells in MU-Opioid Receptor-Mediated Vasodilation in the Rat Retina. AB - PURPOSE: Our recent study demonstrated that herkinorin, a non-opioid MU-receptor agonist derived from salvinorin A, dilates retinal arterioles through stimulation of MU-opioid receptors in rats. Activation of neuronal nitric oxide (NO) synthase and the presence of ganglion cells in the retina appear to be crucial for inducing MU-opioid receptor-mediated retinal vasodilation. In the present study, we examined the role of the interaction between neurons and glia in the retinal vasodilator mechanism involving MU-opioid receptors in rats. MATERIALS AND METHODS: The localization of MU-opioid receptors and neuronal NO synthase (nNOS) in the rat retina was examined using immunohistochemistry. The retinal vascular responses were evaluated by measuring the diameter of retinal arterioles in in vivo fundus images. Both systemic blood pressure and heart rate were continuously recorded. RESULTS: Immunoreactivity of MU-opioid receptors was found in ganglion cells and astrocytes, while that of nNOS was detected in ganglion cells and amacrine cells. Herkinorin increased retinal arteriolar diameter without significantly changing mean blood pressure and heart rate. The retinal vasodilator response to herkinorin was significantly attenuated by treatment with glial toxins (fluorocitrate and disialoganglioside-GD1b). The glial toxins markedly prevented vasodilation induced by intravitreal injection, but not by intravenous infusion, of NOR3, an NO donor. CONCLUSION: These results suggest that retinal glial cells play an important role in the MU-opioid receptor mediated retinal vasodilation in rats. Stimulation of MU-opioid receptors on retinal ganglion cells may affect the activity of glial cells, thereby changing retinal vascular tone. PMID- 29172737 TI - Relationship between shift work schedule and self-reported sleep quality in Chinese employees. AB - Few studies have reported on the effects of fixed and rotating shift systems on the prevalence of sleep disturbance. Thus, in this study, the relationships between different work schedules and sleep disturbance in Chinese workers were investigated. A total of 2180 workers aged 19-65 years responded to the self report questionnaire on shift work schedule (fixed day-shift, fixed night-shift, two-shift or three-shift system), working hours a day, and working days a week, physical effort, subjective sleep quality and subjective mental state. It was found that the rotating shift workers, namely, two- and three-shift workers, exhibited higher risks of sleep disturbance than with the fixed day-shift workers did (OR 1.37; 95% CI 1.07to 1.74; and OR 2.19; 95% CI 1.52 to 3.15, respectively). The risk was particularly high among two- or three-shift workers who worked more than 8 hours a day or more than 5 days a week and among three shift workers who reported both light and heavy physical effort at work. Moreover, the two- and three-shift workers (rotating shift workers) suffered from poorer sleep quality than the fixed night shift workers did (OR 1.84; 95% CI 1.01 to 3.32; and OR 2.94; 95% CI 1.53 to 5.64, respectively). Consequently, rotating shift work (two- and three-shift work) is a risk factor for sleep disturbance, and the fixed work rhythm may contribute to the quality of sleep.

PMID- 29172739 TI - Effect of aquatic exercise on mental health, functional autonomy, and oxidative dysfunction in hypertensive adults. AB - The aquatic exercise is an effective non-pharmacological therapy for prevention and control of hypertension. The objective of the present study was to investigate the effect of aquatic exercise on mental health, functional autonomy, and oxidative dysfunction in hypertensive adults. Methodologically 29 adults (mean age 53 +/- 7.5 years) were included in the study, and were randomly grouped as hypertensive (n = 16) and non-hypertensive (n = 13). Both groups underwent low intensity aquatic exercise program for 12 weeks. Outcomes were evaluated at week 0 and 12. The values for the following parameters decreased in the hypertensive group post training: anxiety (-6.2 +/- 2 score; 60%), Timed Up and Go test (-7.4 +/- 0.3 sec; 30%), protein carbonylation (-0.15 +/- 0.03 nmol/mg protein; 50%), nitric oxide (12.4 +/- 6 nmol/mg protein; 62%), interleukin-6 (-27.6 +/- 5.7 pg/mg protein; 46%), and tissue necrosis factor-alpha (-52.4 +/- 3.8 pg/mg protein; 40%); however, the values of the following parameters increased before training: Berg score (56 +/- 2; 7.8%), flexibility (27 +/- 1 cm; 71%); glutathione (3.1 +/- 1.3 nmol/mg protein; 138%), and superoxide dismutase (1.6 +/ 0.4 nmol/mg; 166%). In conclusion, we suggest that low-intensity aquatic exercise program improved anxiety, functional autonomy, and oxidative dysfunction in hypertensive adults. PMID- 29172740 TI - The choroid plexus harbors a circadian oscillator modulated by estrogens. AB - The suprachiasmatic nucleus (SCN) of the hypothalamus is considered the master circadian oscillator in mammals. However, extra-SCN structures in the brain also display daily rhythms. Recently, we have demonstrated that the choroid plexus (CP) expresses core clock genes that are subjected to circadian regulation in a sex-dependent manner. By using CP explants cultured from female knock-in mice carrying the Period-luciferase transgene, we show that CP exhibits endogenous circadian rhythms of PERIOD2::LUCIFERASE expression. Furthermore, we demonstrate that estrogen declines following ovariectomy modulates the daily rhythm expression of Bmal1, Per1 and Per2 in female rat CP, corroborating data obtained in experiments where rat CP epithelial cell (CPEC) cultures were incubated with 17beta-estradiol (E2). The molecular mechanism underlying these effects was also investigated, and we provide evidence that the estrogen receptor (ER) mediates the response of clock genes to E2. In conclusion, our study proves that the CP harbors a circadian oscillator that is modulated by estrogens and demonstrates that E2 regulation occurs through an estrogen-receptor-dependent mechanism. PMID- 29172741 TI - Effects of Intravitreal Aflibercept on Galectin-1 and Vascular Endothelial Growth Factor-A Plasma Levels in Patients with Diabetic Retinopathy. AB - PURPOSE: To analyze the interaction between aflibercept and galectin-1 and evaluate the plasma levels of galectin-1 and vascular endothelial growth factor (VEGF)-A after intravitreal injection of aflibercept in patients with diabetic retinopathy (DR). METHODS: Interaction of galectin-1 with aflibercept was determined via immunoprecipitation. Seventeen patients with type 2 diabetes and diabetic macular edema (DME) were each treated with a single intravitreal injection of aflibercept (2.0 mg, 50 uL) monthly for three consecutive months. Plasma galectin-1 and VEGF-A levels were measured just before an injection was administered, 1 week after the first injection, and 2 months after the last injection. Nineteen age- and sex-matched healthy participants served as controls. RESULTS: Irrespective of the tested galectin-1 concentration, 24% of added galectin-1 was precipitated by aflibercept. Baseline plasma concentrations of galectin-1 were 22.0 and 23.0 ng/mL in the control and aflibercept-treated groups, respectively. Systemic galectin-1 levels increased to 27.0 and 24.0 ng/mL at 7 days and 4 weeks, respectively, after treatment. At week 8, plasma galectin 1 levels significantly increased to 36.0 ng/mL. This level persisted for 20 weeks. Systemic VEGF-A levels significantly reduced to below the minimum detectable dose in 16 DME patients at 7 days after treatment. This level persisted for 4 weeks. Plasma VEGF-A levels were reduced at weeks 8 (p = 0.099) and 20 (p = 0.023). Decreased plasma VEGF-A levels were observed in all patients after treatment. CONCLUSION: We confirmed that physiological aflibercept levels precipitate galectin-1 in in vitro assays. Additionally, systemic upregulation of galectin-1 might be induced by intravitreal aflibercept, which may be relevant in the clinical outcomes of DR treatment. PMID- 29172742 TI - The risk of right ventricular failure with current continuous-flow left ventricular assist devices. AB - INTRODUCTION: Right ventricular failure (RVF) still results as the major cause of morbidity and mortality after left ventricular assist device (LVAD) implantation. Despite overall improved outcomes and lower rates of RVF with the use of the newer, continuous-flow (CF) LVADs over pulsatile-flow devices, and development of clinical prediction scores to facilitate preoperative identification of patients at risk for RVF after implantation, RVF occurs in 13% to 40% of continuous-flow device. Areas covered: In this article, a review has been carried out on the current evidence for preoperative assessment of RV function and RVF risk for appropriate patient selection mainly focusing on current imaging and invasive assessment tools. Expert commentary: According to all findings, it is recommended that measurements of RV function should be included in all risk predictions models and that standardization of echocardiographic and hemodynamic evaluation protocols be adopted before and after device implantation across LVAD centers. The balance of well-accepted and fixed multiple variables might be able to better predict the outcomes in such a delicate clinical panorama. PMID- 29172744 TI - Identification of mothball powder composition by float tests and melting point tests. AB - INTRODUCTION: The aim of the study was to identify the composition, as either camphor, naphthalene, or paradichlorobenzene, of mothballs in the form of powder or tiny fragments by float tests and melting point tests. METHODS: Naphthalene, paradichlorobenzene and camphor mothballs were blended into powder and tiny fragments (with sizes <1/10 of the size of an intact mothball). In the float tests, the mothball powder and tiny fragments were placed in water, saturated salt solution and 50% dextrose solution (D50), and the extent to which they floated or sank in the liquids was observed. In the melting point tests, the mothball powder and tiny fragments were placed in hot water with a temperature between 53 and 80 degrees C, and the extent to which they melted was observed. Both the float and melting point tests were then repeated using intact mothballs. Three emergency physicians blinded to the identities of samples and solutions visually evaluated each sample. RESULTS: In the float tests, paradichlorobenzene powder partially floated and partially sank in all three liquids, while naphthalene powder partially floated and partially sank in water. Naphthalene powder did not sink in D50 or saturated salt solution. Camphor powder floated in all three liquids. Float tests identified the compositions of intact mothball accurately. In the melting point tests, paradichlorobenzene powder melted completely in hot water within 1 min while naphthalene powder and camphor powder did not melt. The melted portions of paradichlorobenzene mothballs were sometimes too small to be observed in 1 min but the mothballs either partially or completely melted in 5 min. Both camphor and naphthalene intact mothballs did not melt in hot water. CONCLUSIONS: For mothball powder, the melting point tests were more accurate than the float tests in differentiating between paradichlorobenzene and non-paradichlorobenzene (naphthalene or camphor). For intact mothballs, float tests performed better than melting point tests. Float tests can identify camphor mothballs but melting point tests cannot. We suggest melting point tests for identifying mothball powder and tiny fragments while float tests are recommended for intact mothball and large fragments. PMID- 29172743 TI - Impact of hyperhomocysteinemia on insulin resistance in patients with H-type hypertension. AB - BACKGROUND: Hypertension (HT) and hyperhomocysteinemia (HHcy) had been considered influential factors of insulin resistance. H-type HT occurred as HHcy associated with HT. The impact of HHcy on insulin resistance in H-type HT patients remains to be estimated. The interacted effects of HHcy and HT on insulin resistance are still unclear. METHODS: A total of 790 patients were recruited and classified into four groups according to their blood pressure and plasma Hcy level, i.e., control group (C group), HHcy group (HHcy subjects without HT), HT group (HT subjects without HHcy), and H group (subjects with H-type HT). The relationship between HHcy and insulin resistance, as estimated using the HOMA-IR, was analyzed and related to blood pressure. RESULTS: HOMA-IR values were significantly higher in the HHcy group than the C group (2.97 (2.23-4.01) versus 2.54 (1.87-3.58), P < 0.01). H-type HT patients showed more severe insulin resistance than those who only got HT (3.58 (2.59-4.85) versus 2.96 (1.90-3.49),P < 0.01). Moreover, HOMA IR values were positively correlated with Hcy levels (r = 0.26, P < 0.01). After correcting for possible risking factors, a linear regression relationship between insulin resistance and HHcy was found (beta = 0.158, P < 0.01). HHcy was interacted with HT on the exacerbation of insulin resistance in H-type HT patients (beta = 0.501, P < 0.01). CONCLUSIONS: HHcy obviously exacerbate insulin resistance, especially in H-type HT patients. HHcy and HT have a multiplicative effect on metabolic dysfunction, which may help to interpret why these patients are suffering a high risk of cardiovascular disease and stroke. PMID- 29172745 TI - Association of ACE gene A2350G and I/D polymorphisms with essential hypertension in the northernmost province of China. AB - Angiotensin converting enzyme (ACE) gene, as a strong candidate gene for essential hypertension(EH), has been extensively studied. In this study, we carried out a population-based case-control study to explore whether ACE gene I/D and A2350G polymorphisms could consider to be risk factors for EH. A total of 2040 subjeces were recruited from Chinese Han in this study, out of which 1010 were cases and 1030 were normotensive individuals. ACE gene A2350G and I/D polymorphisms were amplified by polymerase chain reaction (PCR) and A2350G polymorphism was detected after restriction enzyme digestion with BstuI. Besides, we choosed 10% samples randomly sequencing to verify the accuracy of results. Genotype and allele frequencies distribution of I/D and A2350G in EH and control groups were significantly different. After grouped by sex or age, there were still statistical significances for two polymorphisms. In dominant and recessive model of A2350G, we found significant differences between two groups, respectively. For ACE I/D polymorphism, we observed that the existence of dramatical difference in dominant model between two groups, while in recessive model, marginally significant difference was found. Among the four haplotypes composed by ACE gene A2350G and I/D, haplotype G-D reached the statistical significance in two groups, and exhibited to be a risk factor for the development of EH, whose P < 0.001 and OR 95%CI = 1.639(1.435-1.872), while the other haplotypes were the protective factors and decreased the susceptibility to EH(P < 0.05). ACE gene A2350G and I/D polymorphisms were associated with increasing the risk of suffering from EH in the northernmost province of China individuals, with D allele and G allele individuals had a higher risk of EH(OR = 1.443, 95%CI = 1.273-1.636 and OR = 1.481, 95%CI = 1.303-1.684). PMID- 29172750 TI - Parallel short forms for the assessment of activities of daily living in cardiovascular rehabilitation patients (PADL-cardio): development and validation. AB - PURPOSE: To develop and validate parallel short forms for the assessment of activities of daily living in cardiac rehabilitation patients (PADL-cardio I & II). METHOD: PADL-cardio I & II were developed based on a sample of 106 patients [mean age = 57.6; standard deviation (SD) = 11.1; 72.6% males] using Rasch analysis and validated with a sample of 81 patients (mean age = 59.1; SD = 11.1; 88.9% males). All patients answered PADL-cardio and the Short Form 12 Health Survey. RESULTS: Both versions of PADL-cardio are composed of 10 items. The fit to the Rasch model was given documented by a non-significant Item-trait interaction score (PADL-cardio I: chi2 = 31.08, df = 30, p = 0.41; PADL cardio II: chi2 = 45.6, df = 40, p = 0.25). The two versions were free of differential item functioning. Person-separation reliability was 0.72/0.78 and unidimensionality was given. The two versions correlated with r = 0.98 and the correlation between PADL-cardio and the underlying item bank was 0.99 for both versions. Concurrent validity is indicated through correlations with the Short Form 12 Health Survey (r = -0.37 to -0.40). CONCLUSION: PADL-cardio provides a short and psychometrically sound option for the assessment of activities of daily living in cardiovascular rehabilitation patients. The two versions of PADL-cardio are equivalent. Hence, they can be used to reduce practice and retest effects in repeated measurement, facilitating the longitudinal assessment of activities of daily living. Implications for Rehabilitation New parallel test forms for the assessment of activities of daily living in cardiac rehabilitation (PADL-cardio I & PADL-cardio II) are available. PADL-cardio I & II consist of 10 items and are therefore especially timesaving. Concurrent validity is given through correlations with the Short Form Health Survey 12. Therapeutic success could be determined more precisely by the parallel forms reducing practice and retest effects. PMID- 29172746 TI - Pazopanib for renal cell carcinoma leads to elevated mean arterial pressures in a murine model. AB - BACKGROUND: In the setting of metastatic RCC (mRCC), pazopanib is approved as first line therapy. Unfortunately treatment may lead to cardiotoxicity such as hypertension, heart failure, and myocardial ischemia. OBJECTIVE: Define the in vivo role of pazopanib in the development of cardiotoxicity. METHODS: Wild type mice were dosed for 42 days via oral gavage, and separated into control and treatment (pazopanib) groups. Baseline ECG's, echocardiograms, and blood pressures were recorded. At the conclusion of the study functional parameters were again recorded, and animals were used for pathological, histological, and protein analysis. RESULTS: After 2 weeks of dosing with pazopanib, the treatment group exhibited a statistically significant increase in mean arterial pressure compared to control mice (119 +/- 11.7 mmHg versus 108 +/- 8.2 mmHg, p = 0.049). Treatment with pazopanib led to a significant reduction in the cardiac output of mice. CONCLUSION: Our findings in mice clearly demonstrate that treatment with pazopanib leads to a significant elevation in blood pressure after 2 weeks of dosing and this persists for the duration of dosing. The continued development of the cardio-oncology field will be paramount in providing optimal oncologic care while simultaneously improving cardiac outcomes through further investigation into the mechanisms of CV toxicity. PMID- 29172749 TI - Reduction-responsive PEtOz-SS-PCL micelle with tailored size to overcome blood brain barrier and enhance doxorubicin antiglioma effect. AB - A series of novel reduction-responsive micelles with tailored size were designed and prepared to release doxorubicin (DOX) for treating glioma, which were developed based on amphiphilic block copolymer poly (2-ethyl-2-oxazoline)-b-poly (epsilon-caprolactone) (PEtOz-SS-PCL) and the micelle size could be regulated by designing the polymer structure. The DOX-loaded PEtOz-SS-PCL micelles had small size and rapid drug release in reductive intracellular environments. Biodistribution and in vivo imaging studies in C6 glioma mice tumor model showed that DOX loaded PEtOz-SS-PCL43 micelles with the smallest size had superior accumulation and fast drug release in tumor sites. In vivo antitumor activity demonstrated that DOX-loaded PEtOz-SS-PCL43 micelles improved antitumor efficacy in contrast to PEtOz-SS-PCL micelles with larger size toward the orthotopic C6 Luci cells-bearing mice. This study shows great potential in tailoring the micelle size and introducing the responsive bonds or compartment for intracellular drug delivery and release in glioma treatment by designing the architecture of the polymer.

PMID- 29172751 TI - "This one will delay us": barriers to accessing health care services among persons with disabilities in Malawi. AB - PURPOSE: This paper explores the barriers which people with disabilities experience in accessing health care services in Malawi. METHODOLOGY: Fifty-two in depth interviews were conducted with people with various types of disabilities. These interviews were conducted in four districts in Malawi: Blantyre and Phalombe in the Southern Region; Ntchisi in the Central Region, and Rumphi in the North. A team of trained research assistants conducted the interviews. RESULTS: The major challenges that people with disabilities experience include the cost of accessing health care, long distances to health facilities, lack of transport, hilly terrains and flooding of rivers during the rainy season, communication challenges with the health providers and poor attitude of health workers. Some of these challenges are not unique to people with disabilities, but constitute more of a problem among people with disabilities. CONCLUSION: There is a need to address these challenges through the expansion of the provision of assistive devices, implementing comprehensive outreach services targeting people with disabilities and strengthening the links between key component of access to quality health care. Attitudinal barriers and lack of resources remain major challenges. Implications for rehabilitation Though people with disabilities face challenges accessing health care world-wide, the challenges are greater in low income countries. The current study in Malawi confirms this. Major challenges include costs of care, transport costs, and inaccessible facilities. Lack of health worker awareness and attitudinal barriers are major issues of concern. It is imperative, given this situation, that effort is spent in Malawi and similar contexts on dealing with issues of stigma and discrimination especially in the health care sector. It is also important to explore cost-effective ways of assisting people with disabilities accessing appropriate transport, which should be seen as part of the healthcare system. Though the cost of providing equitable care may be high in low-income contexts, this is a human right. Training and creating an accessible and disability-friendly service environment is a key priority. PMID- 29172753 TI - Design and characterization of calcium-free in-situ gel formulation based on sodium alginate and chitosan. AB - The aim of this study was to prepare and evaluate calcium-free sustained release drug delivery systems, based on the in-situ gelation of oral suspensions containing chitosan, sodium alginate and Ranitidine as drug model. The combined effects of polymer concentrations and their interactions on the rheological characteristics of both gels and suspensions and, on the kinetics of drug release were evaluated by using a central composite face-centered design. Rheological analysis showed that suspensions were potentially stable, with a viscosity increased by 1000 times compared to that of water. In addition, the obtained gels were consistent; their storage modulus could reach values close to 50 kPa when alginate concentration was greater than 7.5 g/100 mL and chitosan was fixed to 0.5 g/100 mL. In these conditions gels should have a higher gastric residence time, in comparison to the standard gastric emptying time (~2 h). Evaluation of the in-vitro release kinetics of Ranitidine showed that the association of the lowest concentration of chitosan (0.5 g/100 mL) with higher alginate concentrations generates sustained release kinetics profiles. The time corresponding to 63% of release was found close to 1.5 h, in which case the process is governed by Fickian diffusion. Finally, calcium-free alginate-chitosan based on the in-situ gelation of suspensions is advantageous as a drug delivery system for sustained-release. PMID- 29172755 TI - Demographic and clinical features of atrial myxomas: A case series analysis. AB - AIM: Cardiac myxomas are uncommon tumors and have a wide clinical spectrum. Their diagnosis can therefore be elusive because symptoms are nonspecific and misleading. Our aim was to characterize and analyze the clinical findings in patients presenting with cardiac myxomas. METHODS: We conducted a retrospective, hospital-based case study using the electronic records of a Spanish general hospital, caring for a population of 155,000. Patients' data were collected for the period between 2000 and 2016. Demographic data and clinical features were analyzed. RESULTS: Our series included 22 patients over a 15-year period (annual incidence of 0.94 patients per 100,000 inhabitants). Men were predominant (68%) and the median age was 69 years. Cardiac (40.9%), systemic (27.3%), and neurological manifestations (13.6%) were the main clinical features. Left atrium (81.8%) was the predominant location. Surgical treatment was performed in all patients and the overall outcome was good in all cases. CONCLUSIONS: Cardiac myxomas are uncommon, benign tumors, predominantly located in the left atrium and mainly affecting middle-aged and elderly male patients. Congestive heart failure, stroke, and systemic symptoms, although misleading and nonspecific, are the most frequent forms of clinical presentation.

AB - PURPOSE: Mechanical ventilation has allowed a greater number of patients with Duchenne muscular dystrophy (DMD) to transition into adulthood. However, the role of a child's parent as a caregiver lasts throughout the child's lifetime. We explored parents' experiences of prolonged caregiving using serial interviews, analyzed using constructivist grounded theory. MATERIALS AND METHODS: Fourteen parents (average age 53.9 years) with sons with DMD (average age 23.2 years) were interviewed two to four times, over a 3-year period. Data were analyzed using a grounded theory approach. RESULTS: Two categories of responses were defined as strengths, and four as weaknesses. The strengths were related to family member support and confidence in parenting ability. The weaknesses were related to the anticipation of aging with the ongoing burden of caring for adult sons, regrets, sharing of responsibility versus having a fixed role as the primary caregiver, and economic burden. The weaknesses became more pronounced as the duration of caregiving increased. Parents' acceptance of and immobilization in their role of primary caregiver led to prolonged derivative dependency. CONCLUSION: Practical support for parental caregivers, who experience a marked increase in the duration of their caregiving role while facing their own aging-related challenges, are required. Implications for Rehabilitation Children with DMD are living longer and are transitioning into adulthood; a successful transition involves becoming as independent as possible and maintaining a positive sense of personal identity. Despite entering adulthood, the parental caregiver's caregiving role continues. Rehabilitation professionals, who are able to provide long-term, continued support from childhood into adulthood, should be aware that parental caregivers' weakness are exacerbated as the duration of caregiving increases. Families affected by DMD require multifaceted support that should include support for the parental caregiver. PMID- 29172757 TI - Systemic effects of angiogenesis inhibition alter pharmacokinetics and intratumoral delivery of nab-paclitaxel. AB - Angiogenesis is critical to the growth of tumors. Vascularization-targeting agents, with or without cytotoxic drugs, are widely used for the treatment of several solid tumors including esophagogastric adenocarcinoma. However, little is known about the systemic effects of anti-angiogenic therapies and how this affects the pharmacokinetics and intratumoral delivery of cytotoxic agents. In this study, patient-derived xenograft mouse models of esophageal adenocarcinoma were used to identify the effects of DC101, a murine vascular endothelial growth factor receptor 2 (VEGFR2) inhibitor, on the pharmacokinetics and the intratumoral uptake of nab-paclitaxel (NPTX). We showed that DC101 had large systemic effects resulting in decreased vasculature of intraperitoneally located organs. As a consequence, after intraperitoneal administration of NPTX, plasma uptake (5.029 +/- 4.35 vs. 25.85 +/- 2.27 uM) and intratumoral delivery (5.48 +/- 5.32 vs. 38.49 +/- 2.805 pmol/mg) of NPTX were greatly impaired in DC101-treated animals compared to control animals. Additionally, routes of NPTX elimination were altered upon angiogenesis inhibition; unchanged renal clearance and intraperitoneal accumulation of NPTX were observed, but NPTX levels were significantly lower in the liver. Histological examination of the intestine revealed a reduced thickness of the intestinal wall following DC101 therapy and suggested seepage of intraperitoneally injected NTPX through the intestinal wall to explain its reduced uptake in liver, plasma, and tumor tissue. These data explain several adverse effects observed in the clinic when using anti-angiogenic therapies and also imply that the combined use of anti-angiogenesis and cytotoxic agents in both preclinical and clinical setting is still suboptimal. PMID- 29172758 TI - Deformity and Clinical Outcomes Following Operative Correction of Charcot Foot: A New Classification With Implications for Treatment. AB - BACKGROUND: The historic treatment of Charcot foot arthropathy has been immobilization during the active phase of the disease process, followed by accommodative bracing of the acquired deformity. Evidence derived from modern patient-reported outcomes investigations has convinced many surgeons to attempt operative correction of the acquired deformity with a goal of improving quality of life. METHODS: Over a 12-year period, 214 patients (9 bilateral) underwent reconstruction of the acquired deformity associated with midtarsal Charcot foot arthropathy. Over time, 3 patterns of deformity were observed based on weight bearing pattern, relationship of the forefoot to the hindfoot, and integrity of the talocalcaneal joint. A valgus deformity pattern was present in 138, varus in 48, and dislocation of the talocalcaneal joint in 37. A consistent operative strategy was employed. Surgery included percutaneous tendon-Achilles lengthening, resection of infection when present, attempted correction of the structural deformity by wedge resection at the apex of the deformity, and immobilization with a 3-level static circular external fixator. Additional deformity pattern specific procedures were added over time. Clinical outcomes were based on the historic metrics of limb salvage and resolution of infection and the functional metric of the ability to walk with commercially available therapeutic footwear. RESULTS: Seven patients died within a year of surgery, and 15 underwent partial- or whole-foot amputation. Overall, 173 of 223 feet (77.6%) achieved a favorable clinical outcome. Patients with a valgus deformity pattern were most likely to achieve a favorable clinical outcome (120 of 138, 87.0%). Patients with a dislocation pattern were less likely to achieve a favorable clinical outcome (26 of 37, 70.3%), and those with a varus deformity pattern were least likely to achieve a favorable clinical outcome (27 of 48, 56.3%). CONCLUSIONS: Operative correction of the acquired deformity of Charcot foot arthropathy was performed with a goal of improving quality of life. Stratification of patients by deformity pattern allowed alterations of the basic surgery to afford improved outcomes. In addition to achieving historic goals of resolution of infection and limb salvage, almost 80% of the patients were able to achieve the functional goal of independent ambulation with commercially available therapeutic footwear. The clinical outcomes achieved in this retrospective case series appear to support the modern paradigm of operative correction of deformity in this complex patient population. This realistic appreciation of outcome expectations should both be helpful in counseling patients on the risk-benefit ratio associated with surgery and provide a benchmark to measure newer strategies of treatment. LEVEL OF EVIDENCE: Level IV, retrospective case series. PMID- 29172759 TI - Co-delivery of gambogic acid and TRAIL plasmid by hyaluronic acid grafted PEI PLGA nanoparticles for the treatment of triple negative breast cancer. AB - Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-based combination therapy and gene therapy are new strategies to potentially overcome the limitations of TRAIL, however, the lack of efficient and low toxic vectors remains the major obstacle. In this study, we developed a hyaluronic acid (HA) decorated polyethylenimine-poly(d,l-lactide-co-glycolide) (PEI-PLGA) nanoparticle (NP) system for targeted co-delivery of TRAIL plasmid (pTRAIL) and gambogic acid (GA) in triple-negative breast cancer (TNBC) therapy. GA was encapsulated into the core of the PEI-PLGA NPs while pTRAIL was adsorbed onto the positive NP surface via charge adsorption. The coating of HA on PEI-PLGA NPs functions as a targeting ligand by binding to CD44 receptor of TNBC cells and a shell to neutralize the excess positive charge of inner NPs. The resultant pTRAIL and GA co-loaded HA-coated PEI-PLGA NPs exhibited spherical shape (121.5 nm) and could promote the internalization of loaded cargoes into TNBC cells through the CD44 dependent endocytic pathway. The dual drug-loaded NPs significantly augmented apoptotic cell death in vitro and inhibited TNBC tumor growth in vivo. This multifunctional NP system efficiently co-delivered GA and pTRAIL, thus representing a promising strategy to treat TNBC and bringing forth a platform strategy for co-delivery of therapeutic DNA and chemotherapeutic agents in combinatorial TNBC therapy. PMID- 29172760 TI - Adjusted comparison of daratumumab monotherapy versus real-world historical control data from the Czech Republic in heavily pretreated and highly refractory multiple myeloma patients. AB - OBJECTIVES: We conducted an adjusted comparison of progression-free survival (PFS) and overall survival (OS) for daratumumab monotherapy versus standard of care, as observed in a real-world historical cohort of heavily pretreated multiple myeloma patients from Czech Republic. METHODS: Using longitudinal chart data from the Registry of Monoclonal Gammopathies (RMG) of the Czech Myeloma Group, patient-level data from the RMG was pooled with pivotal daratumumab monotherapy studies (GEN501 and SIRIUS; 16 mg/kg). RESULTS: From the RMG database, we identified 972 treatment lines in 463 patients previously treated with both a proteasome inhibitor and an immunomodulatory drug. Treatment initiation dates for RMG patients were between March 2006 and March 2015. The most frequently used treatment regimens were lenalidomide-based regimens (33.4%), chemotherapy (18.1%), bortezomib-based regimens (13.6%), thalidomide-based regimens (8.0%), and bortezomib plus thalidomide (5.3%). Few patients were treated with carfilzomib-based regimens (2.5%) and pomalidomide-based regimens (2.4%). Median observed PFS for daratumumab and the RMG cohort was 4.0 and 5.8 months (unadjusted hazard ratio [HR], 1.14; 95% confidence interval [CI], 0.94 1.39), respectively, and unadjusted median OS was 20.1 and 11.9 months (unadjusted HR, 0.61; 95% CI, 0.48-0.78), respectively. Statistical adjustments for differences in baseline characteristics were made using patient-level data. The adjusted HRs (95% CI) for PFS and OS for daratumumab versus the RMG cohort were 0.79 (0.56-1.12; p = .192) and 0.33 (0.21-0.52; p < .001), respectively. CONCLUSIONS: Adjusted comparisons between trial data and historical cohorts can provide useful insights to clinicians and reimbursement decision makers on relative treatment efficacies in the absence of head-to-head comparison studies for daratumumab monotherapy. PMID- 29172761 TI - A longitudinal interprofessional simulation curriculum for critical care teams: Exploring successes and challenges. AB - Interprofessional care teams are the backbone of intensive care units (ICUs) where severity of illness is high and care requires varied skills and experience. Despite this care model, longitudinal educational programmes for such workplace teams rarely include all professions. In this article, we report findings on the initial assessment and evaluation of an ongoing, longitudinal simulation-based curriculum for interprofessional workplace critical care teams. The study had two independent components, quantitative learner assessment and qualitative curricular evaluation. To assess curriculum effectiveness at meeting learning objectives, participant-reported key learning points identified using a self assessment tool administered immediately following curricular participation were mapped to session learning objectives. To evaluate the curriculum, we conducted a qualitative study using a phenomenology approach involving purposeful sampling of nine curricular participants undergoing recorded semi-structured interviews. Verbatim transcripts were reviewed by two independent readers to derive themes further subdivided into successes and barriers. Learner self-assessment demonstrated that the majority of learners, across all professions, achieved at least one intended learning objective with senior learners more likely to report team-based objectives and junior learners more likely to report knowledge/practice objectives. Successes identified by curricular evaluation included authentic critical care curricular content, safe learning environment, and team comradery from shared experience. Barriers included unfamiliarity with the simulation environment and clinical coverage for curricular participation. This study suggests that a sustainable interprofessional curriculum for workplace ICU critical care teams can achieve the desired educational impact and effectively deliver authentic simulated work experiences if barriers to educational engagement and participation can be overcome. PMID- 29172762 TI - Cultural Guides, Cultural Critics: Distrust of Doctors and Social Support during Mental Health Treatment. AB - Research on relationships and health often interprets culture as the passively transmitted "content" of social ties, an approach that overlooks the influence of cultural resources on relationships themselves. I propose that mental health patients seek social support partly based on cultural resources held by their network members, including members' medical knowledge and beliefs. I test hypotheses using data from the Indianapolis Network Mental Health Study, an egocentric network survey of new mental health patients ( N = 152) and their personal relationships ( N = 1,868). Results from random-intercept regressions show that patients obtain support from network members who trust doctors and who have experience with mental problems. In contrast, network members who distrust doctors disproportionately cause problems for patients. I discuss how cultural resources can categorize network members as supportive cultural guides or disruptive cultural critics. Reconsidering how culture shapes relationships clarifies the role of networks during illness management and illustrates their potentially harmful effects. PMID- 29172763 TI - Depression, Work and Family Roles, and the Gendered Life Course. AB - Despite the importance of employment for shaping mental health over the life course, little is known about how the mental health benefits of employment change as individuals age through their prime employment and child-rearing years. This study examines the National Longitudinal Survey of Youth, 1979 Cohort ( N = 8,931), following respondents from their late 20s to mid-50s. Results suggest that among women, the aging of children is especially salient for shaping the mental health consequences of employment. Young children diminish the protective effect of mothers' full- and part-time employment, but the salubrious effects of paid work increase as children get older. The benefit of employment for men's mental health also changes over time, but it is the aging of men themselves rather than their children that alters the magnitude of full-time employment's protective effect. Findings suggest the contribution of employment to life course mental health remains tethered to traditional gender roles. PMID- 29172764 TI - Policy Brief. PMID- 29172765 TI - Interdependent Career Types and Divergent Standpoints on the Use of Advanced Technology in Medicine. AB - This paper uses the case of the uneven use of a robotic technology to explain how physicians with similar training come to engage in different medical practices. I develop a conceptual framework in which their decisions to use advanced technologies are informed by "interdependent career types," a concept that incorporates features of the professional social context of physicians' work and the expertise they use, and reflects how medicine distributes expertise via formal and informal referral structures. I draw on data regarding specialized physicians' differentiated use of this technology over five years as well as interviews with those who continue to use the technology and those who have abandoned it. I argue that interdependent career types stratify physicians' standpoints on multiple dimensions of medical work-including those related to their concerns about reputation, inclinations toward risk, and preferences regarding the use of their bodies. PMID- 29172766 TI - Black Deaths Matter: Race, Relationship Loss, and Effects on Survivors. AB - Close relationships are a resource for mental and physical health that, like other social resources, is unequally distributed in the population. This article focuses on racial disparities in the loss of relationships across the life course. Racial disparities in life expectancy in the United States mean that black Americans experience the deaths of more friends and family members than do white Americans from childhood through later life. I argue that these losses are a unique type of stress and adversity that, through interconnected biopsychosocial pathways, contribute to disadvantage in health over the life course. I focus particularly on how the interconnected pathways associated with loss undermine opportunities for and increase risks to social ties throughout life, adding to disadvantage in health. I call on social scientists and policy makers to draw greater attention to this unique source of disadvantage for black children, adults, and families. PMID- 29172767 TI - Contesting and Differentially Constructing Uncertainty: Negotiations of Contraceptive Use in the Clinical Encounter. AB - Most women of reproductive age have access to highly effective contraception, and all available methods are associated with side effects. Whether a woman will experience side effects is uncertain, however, which can pose challenges for clinicians who discuss the methods with patients. In this study, we analyze 102 contraceptive counseling visits to understand how clinicians discursively construct knowledge in the context of uncertainty. We find that while some present the uncertainty of side effects in a straightforward, patient-accessible way, others negotiate their predictions by (1) differentially constructing uncertainty, suggesting that positive side effects are likely and negative side effects are unlikely, and (2) contesting uncertainty, presenting the risk of serious side effects as controllable. In the end, these strategies deemphasize consideration of negative side effects in women's contraceptive decision making. Our results demonstrate the importance of elucidating the translation, instantiation, and construction of medical uncertainty both in theory and in practice. PMID- 29172768 TI - Planning for Future Care and the End of Life: A Qualitative Analysis of Gay, Lesbian, and Heterosexual Couples. AB - Two key components of end-of-life planning are (1) informal discussions about future care and other end-of-life preferences and (2) formal planning via living wills and other legal documents. We leverage previous work on the institutional aspects of marriage and on sexual-minority discrimination to theorize why and how heterosexual, gay, and lesbian married couples engage in informal and formal end of-life planning. We analyze qualitative dyadic in-depth interviews with 45 midlife gay, lesbian, and heterosexual married couples ( N = 90 spouses). Findings suggest that same-sex spouses devote considerable attention to informal planning conversations and formal end-of-life plans, while heterosexual spouses report minimal formal or informal planning. The primary reasons same-sex spouses give for making end-of-life preparations are related to the absence of legal protections and concerns about discrimination from families. These findings raise questions about future end-of-life planning for same- and different-sex couples given a rapidly shifting legal and social landscape. PMID- 29172769 TI - Health Lifestyles in Adolescence and Self-rated Health into Adulthood. AB - Do health behaviors cluster together as health lifestyles in adolescence? Are these lifestyles socially patterned? Do these lifestyles impact physical health into adulthood? To answer these questions, we employed data from Waves 1 and 4 of the National Longitudinal Study of Adolescent to Adult Health ( n = 7,827). Our latent class analysis revealed four health lifestyles: (a) low risk, (b) moderate risk with substance use, (c) moderate risk with inactivity, and (d) high risk. As suggested by health lifestyle theory, membership in these classes varied according to gender, race-ethnicity, and family structure. Consistent with the life course perspective, regression analyses indicated that those in the high risk lifestyle tend to exhibit worse health in adolescence and adulthood than those in the low-risk lifestyle. Our findings confirm that socially patterned lifestyles can be observed in adolescence, and these lifestyles are potentially important for understanding the distribution of physical health across the early life course.

AB - Social stress resulting from stigma, prejudice, and discrimination-"minority stress"-negatively impacts sexual minority individuals' health and relational well-being. The present study examined how being in a same-sex couple can result in exposure to unique minority stressors not accounted for at the individual level. Relationship timeline interviews were conducted with 120 same-sex couples equally distributed across two study sites (Atlanta and San Francisco), gender (male and female), and relationship duration (at least six months but less than three years, at least three years but less than seven years, and seven or more years). Directed content analyses identified 17 unique couple-level minority stressors experienced within nine distinct social contexts. Analyses also revealed experiences of dyadic minority stress processes (stress discrepancies and stress contagion). These findings can be useful in future efforts to better understand and address the cumulative impact of minority stress on relational well-being and individual health. PMID- 29172773 TI - An update on liquid biopsy analysis for diagnostic and monitoring applications in non-small cell lung cancer. AB - INTRODUCTION: Collection of tumor samples is not always feasible in non-small cell lung cancer (NSCLC) patients, and circulating free DNA (cfDNA) extracted from blood represents a viable alternative. Different sensitive platforms have been developed for genetic cfDNA testing, some of which are already in clinical use. However, several difficulties remain, particularly the lack of standardization of these methodologies. Areas covered: Here, the authors present a review of the literature to update the applicability of cfDNA for diagnosis and monitoring of NSCLC patients. Expert commentary: Detection of somatic alterations in cfDNA is already in use in clinical practice and provides valuable information for patient management. Monitoring baseline alterations and emergence of resistance mutations is one of the most important clinical applications and can be used to non-invasively track disease evolution. Today, different technologies are available for cfDNA analysis, including whole-genome or exome sequencing and targeted methods that focus on a selection of genes of interest in a specific disease. In the case of Next Generation Sequencing (NGS) approaches, in depth coverage of candidate mutation loci can be achieved by selecting a limited number of targeted genes. PMID- 29172774 TI - Trenonacog alfa for prophylaxis, on-demand and perioperative management of hemophilia B. AB - INTRODUCTION: Current treatment for hemophilia B involves replacing the missing coagulation factor IX (FIX) with either plasma-derived or recombinant (r) FIX. Trenonacog alfa is the third normal half-life rFIX that has been granted FDA approval. Area covered: In this review, the authors examine trenonacog alfa for the treatment of hemophilia B including prophylaxis, on-demand and perioperative hemostasis. They compare the PK profile to nonacog alfa and evaluate the drug's efficacy and safety from published studies. Expert opinion: Trenonacog alfa appears to be an effective and safe treatment option for patients with hemophilia B with a PK profile similar to that of nonacog alfa. Despite the advent of extended half-life rFIX and other novel therapeutic approaches, normal half-life rFIX products, including trenonacog alfa, are likely to continue to have a place in hemophilia B treatment for at least the immediate future while the new landscape takes shape, particularly in countries that cannot afford the newer treatments. PMID- 29172775 TI - C/EBPbeta Promotion of MMP3-Dependent Tumor Cell Invasion and Association with Metastasis in Colorectal Cancer. AB - AIMS: Tumor metastasis is a significant obstacle to curing colorectal cancer (CRC). C/EBPbeta is thought to play an important role in CRC invasion and metastasis. In this study, we assessed whether C/EBPbeta-mediated tumor invasion was dependent on MMP3, the expression of which is upregulated by C/EBPbeta. We then determined whether C/EBPbeta upregulation was associated with MMP3 levels and metastatic status in human CRC patients. MATERIALS AND METHODS: A total of 102 patients were recruited for this study. mRNA and protein levels of C/EBPbeta and MMP3 in CRC cell lines and patient specimens were determined by reverse transcription-polymerase chain reaction and western blot, respectively. Tumor cell invasion was analyzed using an in vitro Matrigel Invasion Assay. The correlation between C/EBPbeta and MMP3 expression was determined by Pearson's correlation analysis. RESULTS: Both mRNA and protein levels of MMP3 were upregulated by C/EBPbeta overexpression and downregulated by C/EBPbeta siRNA in HCT116 CRC cell cultures. C/EBPbeta-enhanced tumor cell invasion was inhibited by MMP3 siRNA. In human CRC patients, C/EBPbeta levels were correlated with MMP3 levels and metastatic status. CONCLUSIONS: C/EBPbeta upregulation promoted tumor cell invasion in an MMP3-dependent manner in vitro and was associated with metastatic status in CRC. PMID- 29172776 TI - Self-efficacy in Activities of daily living and symptom management in people with dizziness: a focus group study. AB - BACKGROUND: Self-efficacy is associated with health status, health behaviour and health behaviour change in various chronic health conditions. PURPOSE: To describe self-efficacy in relation to Activities of daily living and symptom management in people with dizziness. MATERIAL AND METHODS: Thirteen women and three men, aged 45-82 years, with persistent dizziness (duration 4 months to 30 years) were recruited from an outpatient physiotherapy unit. A qualitative study was conducted using four focus groups and one individual interview and was then analysed with qualitative content analysis. RESULTS: The participants conveyed, in-depth information concerning two predefined main categories. Self-efficacy in Activities of daily living was related to challenging body positions and motions, environments, social activities, work tasks, and complex cognitive behaviours. Self-efficacy in symptom management was related to distress and aggravated symptoms, unfamiliar environment, and unknown people. CONCLUSIONS: People with dizziness describe how self-efficacy for specific activities varies according to the perceived difficulty of the task, the context of the activity, and day-to-day variations in general wellbeing. The results underscore the importance of targeting self-efficacy in the rehabilitation of people with dizziness. Our findings can guide the rehabilitation process by providing a deeper understanding of self-efficacy judgements in relation to Activities of daily living and symptom management in people with dizziness. Implication for rehabilitation This study adds important in-depth knowledge to the rehabilitation area on self-efficacy beliefs in relation to Activities of daily living and symptom management in people with dizziness. Self-efficacy for specific activities varies according to the perceived difficulty of the task, the context in which the activity takes place and day-to-day variations in perceived general well-being. The results can be used as a topic list to guide rehabilitation efforts in exploring and intervening aspects of people's everyday activities that are affected by low self efficacy judgements. Activities perceived to be crucial to everyday life and important for well-being should be targeted in rehabilitation to increase self efficacy and thereby activity performance and participation in people with dizziness. PMID- 29172777 TI - A novel tumor-activated ALA fusion protein for specific inhibition on the growth and invasion of breast cancer cells MDA-MB-231. AB - OBJECTIVE: The aim of this research was to develop a novel ALA fusion protein for target to the malignant cells surface with high uPAR expression and locally release of the scorpion toxin AGAP in an uPA-cleavable manner. It will provide an effective approach for controlled release of the peptide toxins to treat cancerous cells. METHODS: The ALA fusion proteins were expressed in pichia pastoris, and the recombinant proteins were purified by Ni-NTA affinity chromatography. The proteins were added to human breast cancer cells (MDA-MB-231) and human embryonic kidney cells (HEK-293) in order to investigate the characteristic of selective targeting and releasing of scorpion toxin AGAP in cancer cells with high uPAR expression. The inhibitory effect of ALA on MDA-MB 231, MCF7, LO2 and HEK-293 was evaluated by MTT assay. Moreover, the antiproliferation mechanism of ALA was determined by flow cytometric and western blot analysis. RESULTS: The results showed that ALA could target MDA-MB-231 cells and the scorpion toxin AGAP could be released with high efficiency and selectivity. ALA inhibited the growth and invasion of breast cancer cells MDA MB231. Also, cell apoptosis pathway was found to be associated with the inhibition mechanism of ALA according to the data of flow cytometric and western blot analysis. Therefore, ALA could be a novel antitumor candidate for targeting treatment of malignant cell. CONCLUSIONS: This study successfully demonstrated that fusion of biotoxins with tumor target domain could provide a simple yet effective way to delivery of peptide or protein drugs. PMID- 29172778 TI - Response to afatinib in treatment-naive patients with advanced mutant epidermal growth factor receptor lung adenocarcinoma with brain metastases. AB - BACKGROUND: Brain metastases are observable in 20-40% of non-small cell lung cancer patients, but standard treatments for such metastases may be intolerable to some. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) were found to be effective against mutant-EGFR lung adenocarcinomas, but data regarding their effectiveness, especially for the second-generation EGFR-TKI afatinib, is limited. This study compared key outcomes for afatanib monotherapy versus afatinib combined with whole-brain radiotherapy (WBRT) in treatment-naive lung adenocarcinoma patients harboring EGFR mutations. METHODS: A retrospective review of 28 brain metastatic lung adenocarcinoma patients treated between June 2014 and December 2016 was conducted; 17 were treated with WBRT and maintenance afatinib therapy, while 11 received afatinib monotherapy. RESULTS: The patients were predominantly female (n = 17, 60.7%) and non-smokers (78.6%). Almost all the patients (89.3%) had an Eastern Cooperative Oncology Group performance status of 0-2. The EGFR mutation type consisted of the del19 mutation in 57.1% of the patients (n = 16), while L858R mutations were found in 42.9% (n = 12). The mean number of brain metastases (6.1 +/- 5.0) was higher among the patients treated with afatinib monotherapy, while the mean size of the largest brain metastasis (19.0 +/- 10.5mm) was greater in the afatinib combined with WBRT group. The objective response rates for the afatinib monotherapy and combination therapy groups were 81.8% and 88.2%, respectively. However, the monotherapy group exhibited a significantly higher complete response rate for intracranial lesions (63.6% vs. 17.6%, p = 0.02), and there were no significant differences between the two treatment groups in overall survival or time to treatment failure. CONCLUSION: Afatinib can provide therapeutic efficacy and a good response rate in treatment-naive mutant-EGFR lung adenocarcinoma patients with brain metastases regardless of whether or not they also receive radiotherapy. PMID- 29172779 TI - The effect of magnesium sulfate on gene expression in maternal microvascular endothelial cells. AB - Preeclampsia is a severe complication of pregnancy associated with maternal and fetal morbidity and mortality. To date, magnesium sulfate remains the preferred method of treatment used to reduce the development of eclampsia. Our aim was to investigate the effects of magnesium sulfate on the expression of genes involved with endothelial function in maternal microvascular endothelial cells from both normal and preeclamptic pregnancies. Primary cells from normal pregnancies treated with 80 mg/L magnesium sulfate for 6 h revealed an overall trend of increased expression of angiogenic and vasopressor-related factors by qPCR analyses. Primary cells from preeclamptic pregnancies revealed an overall trend of decreased expression, with significantly lowered levels for vascular endothelial growth factor receptor 2, endothelin, and vascular cell adhesion protein-1. A comparison of treated cells revealed significantly increased levels for endoglin, vascular endothelial growth factor receptor 2, soluble fms-like tyrosine kinase-1, prostacyclin synthase, tumor necrosis factor alpha, tumor necrosis factor receptor 1, and endothelin in normal versus preeclamptic cells following treatment. These results reveal disparate activation of overall expression activity by magnesium sulfate in maternal endothelial cells from normal pregnancies over preeclamptic pregnancies. PMID- 29172780 TI - Understanding modern-day vaccines: what you need to know. AB - Vaccines are considered to be one of the greatest public health achievements of the last century. Depending on the biology of the infection, the disease to be prevented, and the targeted population, a vaccine may require the induction of different adaptive immune mechanisms to be effective. Understanding the basic concepts of different vaccines is therefore crucial to understand their mode of action, benefits, risks, and their potential real-life impact on protection. This review aims to provide healthcare professionals with background information about the main vaccine designs and concepts of protection in a simplified way to improve their knowledge and understanding, and increase their confidence in the science of vaccination ( Supplementary Material ). KEY MESSAGE Different vaccine designs, each with different advantages and limitations, can be applied for protection against a particular disease. Vaccines may contain live-attenuated pathogens, inactivated pathogens, or only parts of pathogens and may also contain adjuvants to stimulate the immune responses. This review explains the mode of action, benefits, risks and real-life impact of vaccines by highlighting key vaccine concepts. An improved knowledge and understanding of the main vaccine designs and concepts of protection will help support the appropriate use and expectations of vaccines, increase confidence in the science of vaccination, and help reduce vaccine hesitancy. PMID- 29172781 TI - Fracture risk assessment in postmenopausal women with diabetes: comparison between DeFRA and FRAX tools. AB - This study aimed to compare the performance of Fracture Risk Assessment Tool (FRAX) with that of Derived FRAX (DeFRA) in estimating fracture risk in a cohort of type-2 diabetes mellitus (T2DM) postmenopausal women. One hundred nineteen T2DM postmenopausal women and 118 consecutive healthy postmenopausal women were enrolled. Fracture risk was assessed with FRAX (adjusted or non- for trabecular bone score, TBS) and DeFRA. Bone mineral density (BMD) and TBS were evaluated by dual-energy X-ray absorptiometry (DXA). The outcome was the presence of vertebral/non-vertebral fragility fractures (FFs). T2DM women showed higher spinal BMD T-score (p < .05), but lower TBS (p < .05), than controls. Diabetic patients had higher prevalence of FFs compared to controls (p < .05), but no significant difference were found in the scores of any of the predictor tools. Differently, in the T2DM group, the scores of DeFRA, FRAX and adjusted-FRAX were significantly (p < .01 for all) higher in fractured compared with non-fractured women. DeFRA showed the best discriminative power among all fracture risk predictor tools (area under curves: DeFra: 0.89; adjusted FRAX: 0.80; non adjusted FRAX: 0.73). In summary, all fracture risk assessment tools appeared to be effective in predicting bone fractures in T2DM postmenopausal women, with DeFRA showing a slightly better diagnostic accuracy.

AB - Although hypoactive sexual desire disorder (HSDD) is the most common sexual complaint, there is no consensus for the ideal treatment. Our study aimed to evaluate the efficacy of treating premenopausal women with HSDD with Tribulus terrestris and its effect on the serum levels of testosterone. We performed a prospective, randomized, double-blind, placebo-controlled trial, with 40 premenopausal women reporting diminished libido, receiving T. terrestris or placebo. The questionnaires FSFI and the QS-F were used to evaluate sexual dysfunction before and after treatment. Patients treated with T. terrestris experienced improvement in total score of FSFI (p < .001) and domains "desire" (p < .001), "sexual arousal" (p = .005), "lubrication" (p = .001), "orgasm" (p <.001), "pain" (p = .030) and "satisfaction" (p = .001). Treatment with placebo did not improve the scores for the "lubrication" and "pain". QS-F scores showed that patients using T. terrestris had improvements in "desire" (p = .012), "sexual arousal/lubrication" (p = .002), "pain" (p = .031), "orgasm" (p = .004) and "satisfaction" (p = .001). Women treated with placebo did not score improvements. Women receiving T. terrestris had increased levels of free (p = .046) and bioavailable (p < .048) testosterone. T. terrestris might be a safe alternative for the treatment of premenopausal women with HSDD as it was effective in reducing the symptoms, probably due to an increase in the serum levels of free and bioavailable testosterone.

AB - The influence of natural drying (ND), hot-air drying (HD), vacuum drying (VD), infrared drying (ID) and freeze drying (FD) on bioactive compounds and bioactivities of Isodon rubescens (Hemsl.) was investigated in this study. The results showed that different drying methods resulted in the differences in bioactive compositions' content, antioxidant and antibacterial activities of extracts from I. rubescens. FD sample possessed the highest content of total phenolics, total flavonoids and several main phenolic compounds, as well as the stronger antioxidant and antibacterial activities, followed by ND, HD and VD, the lowest for ID samples. For this reason, freeze drying would seem to be more advisable for the drying I. rubescens, and future studies could focus on the quality evaluation and optimising various drying parameters. PMID- 29172784 TI - Good agreement between echocardiography and impedance cardiography in the assessment of left ventricular performance in hypertensive patients. AB - BACKGROUND: Impedance cardiography (ICG) is a noninvasive hemodynamic monitoring tool which can define hypertensive patients' hemodynamic profiles and help to tailor antihypertensive therapy. This study assesses the concordance between ICG derived indexes used to evaluate left ventricular performance and transthoracic echocardiography (TTE) in hypertensive patients. METHODS: In this IMPEDDANS post hoc analysis, the ICG-derived indexes are compared with TTE by Bland-Altman method. Statistical significance of the relationship between the values obtained was assessed by generalized linear mixed-effects models. RESULTS: In supine position, Bland-Altman analysis showed good concordance for cardiac output (CO) (mean difference of 0.006 mL/min [-0.120; 0.133]), cardiac index (CI) (mean difference of 0.016 mL/min/m2 [-0.471; 0.504]), pre-ejection period (PEP) (mean difference of -0.216 ms [-4.510; 4.077]), left ventricular ejection time (LVET) (mean difference of -0.140 ms [-6.573; 6.293]), and systolic time ratio (STR) (mean difference of -0.00004 [-0.008; 0.008]). In orthostatic position, good concordance was found for CO (mean difference 0.028 mL/min [-2.036; 1.980]), CI (mean difference -0.012 mL/min/m2 [-1.063; 1.039]), and STR (mean difference 0.101 [0.296; 0.094]). No significant difference between methods was identified by the linear mixed-effects models. CONCLUSION: The ICG-derived indexes CO, CI, PEP, LVET, and STR in supine position have good agreement with TTE. Therefore, ICG can be used to accurately evaluate left ventricular performance.

AB - OBJECTIVE: To examine the contribution of all daily activities, including non music activities, to the overall noise exposure of college student musicians, and to compare their "noise lives" with those of non-musician college students. DESIGN: Continuous week-long dosimetry measurements were collected on student musicians and non-musicians. During the measurement period, participants recorded their daily activities in journals. STUDY SAMPLE: 22 musicians and 40 non musicians, all students (aged 18-24 years) at the University of Connecticut. RESULTS: On every day of the week, musicians experienced significantly higher average exposure levels than did non-musicians. Nearly half (47%) of the musicians' days exceeded a daily dose of 100%, compared with 10% of the non musicians' days. When the exposure due to music activities was removed, musicians still led noisier lives, largely due to participation in noisier social activities. For some musicians, non-music activities contributed a larger share of their total weekly noise exposure than did their music activities. CONCLUSIONS: Compared with their non-musician peers, college student musicians are at higher risk for noise-induced hearing loss (NIHL). On a weekly basis, non music activities may pose a greater risk to some musicians than music activities. Thus, hearing health education for musicians should include information about the contribution of lifestyle factors outside of music to NIHL risk. PMID- 29172787 TI - Adverse perinatal outcomes associated with trial of labor after cesarean section at term in pregnancies complicated by maternal obesity. AB - INTRODUCTION: Obesity is associated with higher risks for intrapartum complications. Therefore, we sought to determine if trial of labor after cesarean section (TOLAC) will lead to higher maternal and neonatal complications compared to repeat cesarean section (RCD). METHODS: This was a retrospective cohort analysis of singleton nonanomalous births between 37 and 42 weeks GA complicated by maternal obesity (body mass index (BMI) >= 30 kg/m2) and history of one or two previous cesarean deliveries. Outcomes were compared between TOLAC and RCD. The maternal outcomes of interest included blood transfusion, uterine rupture, hysterectomy, and intensive care unit admission. Neonatal outcomes of interest included 5-minute Apgar score <7, prolonged assisted ventilation, neonatal intensive care unit admission, neonatal seizures, and neonatal death. RESULTS: There were 538,264 pregnancies included. Compared with RCD, TOLAC was associated with an absolute increase in the following neonatal outcomes: low 5-min Apgar score (0.6%, p < .001), neonatal intensive care unit (NICU) admission (0.8%, p < .001), neonatal seizure (0.1 per 1000 births, p = .037), and neonatal death (0.2 per 1000 births, p = .028). Additionally, TOLAC was associated with an absolute increase in following maternal outcomes: blood transfusion (0.1%, p < .001), uterine rupture (0.18%, p < .001) and ICU admission (0.1%, p = .011). CONCLUSIONS: TOLAC among obesity pregnancies at term increases the risk of maternal and neonatal complications compared with RCD. PMID- 29172786 TI - The Relationship Between Plasma Concentrations of Lutein and Zeaxanthin with Self Reported and Actual Prevalence of AMD in an Irish Population-Based Sample. AB - PURPOSE: To investigate plasma lutein (L) and zeaxanthin (Z) concentrations with grading-confirmed and self-reported prevalence of age-related macular degeneration (AMD). MATERIAL AND METHODS: Data collected from a nationally representative prospective cohort study of community-dwelling adults aged 50 years and over in the Republic of Ireland. Participants underwent a computer assisted personal interview and a center-based health assessment. Plasma concentrations of L and total Z (Z and meso-zeaxanthin [MZ]) were measured by high performance liquid chromatography, and retinal photographs were graded using a version of the AMD International Classification and Grading System. Consumption of supplements containing L and/or Z and/or MZ was recorded as supplement use. Four groups were identified: Group 1 (n = 24): AMD-afflicted and correctly aware; Group 2 (n = 264): AMD-afflicted but unaware; Group 3 (n = 41): AMD-free and incorrectly believed that they were afflicted with the condition; Group 4 (n = 4094): AMD-free and correctly self-reported absence of AMD. RESULTS: Of 4,423 participants with plasma concentrations of L and Z and gradable retinal photographs, 288 (6.5%) were afflicted with AMD, and 65 (1.5%) self-reported AMD. Controlling for family history and age, the relationship between grading confirmed AMD and plasma L was positive and significant (p < 0.001). Mean plasma concentrations of L in Group 2 (mean = 0.2162 +/- 0.132 umol) and Group 4 (mean = 0.2040 +/- 0.121 umol/L) were significantly lower than Group 1 (mean = 0.4691 +/- 0.0.372 umol/L) and Group 3 (mean = 0.3176 +/- 0.0.235 umol/L). Supplement use was reported by 41.7% and 17.1% of participants in Groups 1 and 3, respectively, but only 2.7% and 1.9% of participants in Groups 2 and 4, respectively. CONCLUSION: A belief that one suffers from AMD, whether justified or not, is associated with supplement use and with higher plasma concentrations of L. PMID- 29172788 TI - Estimation of salt intake and sodium-to-potassium ratios assessed by urinary excretion among Japanese elementary school children. AB - Dietary salt intake is largely responsible for the increase in blood pressure with age. It is important to start effective prevention approaches during childhood. In this study, we estimated salt intake and sodium-to-potassium (Na/K) ratios assessed by urinary excretion among elementary school children in Kyoto, Japan. A total of 331 subjects aged 9-11 years participated in school checkups in April 2015. Urinary concentrations of sodium, potassium, and creatinine were measured in first morning urine samples. The subjects' dietary habits were confirmed by questionnaires completed by their parents. The median estimated urinary sodium excretion was 129.0 mmol/day (5.7g/day of salt). In 30.2% of the subjects, their estimated salt intake exceeded their age-specific dietary goal for salt intake recommended by the Dietary Reference Intakes for Japanese 2015. Multivariate linear regression model analysis after adjustment for age revealed a significant positive correlation between seaweeds or fish paste products consumption and the estimated salt intake (p = 0.02 and 0.02, respectively). The median urinary Na/K ratio (mEq/mEq) was 4.5. Multivariate linear regression model analysis revealed a significant negative correlation between fruit consumption and urinary Na/K ratio (p = 0.04). These results suggest that the high sodium intake and the high Na/K ratios occur among Japanese elementary school children, and that the urinary Na/K ratio in children may be reduced by the daily consumption of fruit. PMID- 29172789 TI - Morphometric analysis of human oocytes using time lapse: does it predict embryo developmental outcomes? AB - The aim of this prospective study was to evaluate the relationship between morphometric parameters of metaphase II (MII) oocytes and the morphokinetic behaviour of subsequent embryos derived by intra-cytoplasmic sperm injection (ICSI). The association between oocyte morphometry: (whole oocyte), ooplasm, width of zona pellucida (ZP) and perivitelline space (PVS) and first polar body (PB) with embryo morphokinetic variables, including time of second PB extrusion (tPB2), pronuclei appearance (tPN), pronuclei fading (tPNf), formation of two to eight cells (t2 to t8) and irregular cleavage events [uneven at two cells stage, cell fusion (Fu) and trichomonas mitoses (TM)] were assessed. tPB2, t5 and t8 timings were related to the ooplasm diameter (p = 0.003, r = -0.12; p = 0.001, r = -0.16; p < 0.001 r = -0.36, respectively); otherwise, there were no significant relationships apart from an association between the oocyte morphometry and other morphokinetic parameters, irregular cleavage embryos as well as embryo arrest which approached significance (p > 0.05). Overall, the data showed that morphometric parameters of oocytes did not provide a tool for the prediction of embryo morphokinetic or embryo selection in ICSI cycles. However, ooplasm diameter might be useful as a marker for predicting the timing of embryo cleavage. PMID- 29172790 TI - Detection and reaction thresholds for reverse alarms in noise with and without passive hearing protection. AB - OBJECTIVE: To measure masked detection and reaction thresholds for two reverse alarms (tonal and broadband) and compare results to available standards and psychoacoustic criteria for setting alarm levels. DESIGN: Alarm detection and reaction thresholds were adaptively measured in 80-dBA background noises without hearing protection (Experiment 1), and with a passive earmuff-style hearing protection device (HPD) (Experiment 2). STUDY SAMPLE: Twenty-four young adults with normal hearing in each experimental group. RESULTS: Reverse alarms remained audible at levels well-below background noises [thresholds: -11 to -25 dB signal to-noise ratio (SNR)], with and without the selected HPD. Detection was more influenced by alarm and noise type, while reaction was more susceptible to HPD use. HPD use resulted in lower detection thresholds by up to 2.5 dB compared to unprotected listening but increased reaction thresholds by 5-10 dB depending on the alarm. CONCLUSIONS: Since noise type appears to have a more limited effect on reaction thresholds, adjusting alarms based on a global dBA method appears preferable to methods based on masked detection thresholds. However, while the >0 dB SNR recommended in ISO 9533 seems adequate for unprotected listening, an additional 5-10 dB may be warranted to elicit the same reaction when the selected HPD is used. PMID- 29172791 TI - Teaching interprofessional teamwork skills to health professional students: A scoping review. AB - An expanding body of literature is examining interprofessional teamwork and its effect in healthcare. To produce capable healthcare professionals prepared to participate in interprofessional roles, teamwork training must begin early in health professional students' training. The focus of this scoping review was to explore interprofessional education (IPE) studies designed to teach and/or assess interprofessional teamwork skills to students from two or more different health professions, to find and describe effective pedagogy and assessment strategies. Using a scoping review methodology, 1,106 abstracts were reviewed by three teams of investigators. Eligibility criteria were inclusion of students in interprofessional teams, an intervention to improve interprofessional teamwork skills and assessment of outcomes related to teamwork. Thirty-three studies met the criteria for inclusion. The literature was varied in terms of study design, teaching methods and assessment measures for interprofessional teamwork. The lack of rigorous, comparable studies in this area makes recommending one teaching method or assessment measure over another difficult. Regardless of teaching method, it appears that most learning activities where interprofessional teams interact result in positive changes in student perceptions and attitudes towards IPE and practice. As health education programs seek to incorporate more interprofessional activities into their respective programs, it is important to review methods and measures that would best fit their individual program. This review highlights the importance of standardising the reporting of methods and outcomes for those who wish to incorporate the studied methods into their curricula. PMID- 29172792 TI - Combination therapy for extensively-drug resistant gram-negative bacteria. AB - INTRODUCTION: The ongoing crisis and emergence of extensively-drug resistant (XDR) gram-negative pathogens in the nosocomial setting is worrisome. The limited armamentarium in combination with the increasing resistance rates of last resort antibiotics has led clinicians to re-exploit existing antibiotic classes. Areas covered: Current state of evidence concerning the administration of monotherapy versus combination therapy for the treatment of XDR gram-negative microorganism as well as salvage treatment are presented. Herein, the current knowledge concerning in vitro studies, animal models and clinical studies are discussed in detail. Expert commentary: The efficacy of combination therapy in carbapenemase producing K. pneumoniae is associated with reduced mortality in patients with septic shock and rapidly fatal underlying diseases. There is moderate evidence in support of the use of monotherapy for treating carbapenemase-producing Acinetobacter baumannii infections, however for septic shock patients, cancer patients and infections with an isolate with MIC in the upper limit of susceptibility combination therapy could be recommended. There are currently minimal and of low quality clinical evidence suggesting that combination treatment has no therapeutic advantage over monotherapy for XDR Pseudomonas aeruginosa infections. The in vivo validity of novel compounds and necessity for combination therapy is to be evaluated in future studies particularly for XDR infections. PMID- 29172793 TI - Impact of obstructive sleep apnea on blood pressure and cardiovascular risk factors in Japanese men: A cross-sectional study in work-site group. AB - It has been shown that obstructive sleep apnea (OSA) is related to hypertension and cardiovascular disease; however, the prevalence of OSA in general population and the impact of it on blood pressure especially in Japan has not been well determined. We have conducted a screening test for OSA from 2003 to 2011. In addition, a cross-sectional analysis was performed in 2012 to determine the association of OSA and cardiovascular risk factors in Japanese men (18-69 years of age; mean age, 44.4 +/- 0.2). The study group consisted of 2208 male employees, and OSA was evaluated by using the 4% oxygen desaturation index and apnea-hypopnea index (AHI). The prevalence of mild-to-moderate (5<=AHI<30) and severe (AHI>=30) OSA in the studied subjects were 7.1%, and 6.1%, respectively. Among the 135 severe OSA subjects, 105 (77.8%) had been treated with continuous positive airway pressure. Both systolic and diastolic blood pressures (DBP) were significantly increased in the subjects with severe OSA compared with those without OSA. These associations in DBP remained observed after adjustment for age, body mass index (BMI), estimated glomerular filtration rate, HbA1c, current alcohol intake, current smoking habits, and OSA treatment. DBP in severe OSA subjects were significantly increased in 1807 subjects who were not treated for hypertension or OSA. However, the levels of blood pressures were not decreased by OSA treatment. These results suggest that the prevalence of OSA is relatively high in middle-aged Japanese men and that blood pressures were elevated in the subjects with severe OSA. PMID- 29172794 TI - Mortality in patients with atrial fibrillation and common co-morbidities - a cohort study in primary care. AB - OBJECTIVE: To study the association between cardiovascular co-morbidities and mortality risk in primary care patients with atrial fibrillation. METHODS: The study population included all adults (n = 12,283) >= 45 years diagnosed with AF at 75 primary care centres in Sweden between 2001 and 2007. The outcome was mortality (until 2010) and data were explored for co-morbidities using Cox regression with hazard ratios (HRs). Analyses were performed stratified by sex and by age-group (45-64, 65-74 and >=75 years of age) with adjustment for age, socio-economic factors and relevant co-morbidities. RESULTS: During a mean of 5.8 years (standard deviation 2.4) of follow-up, 3954 (32%) patients died (1971 (35%) women, and 1983 (30%) men). High HRs were found for congestive heart disease (CHF) and cerebrovascular diseases for all age-groups among men and women (except for the 45-64 year old women); for coronary heart disease among the oldest men; for diabetes among the 65-74 year old men and the 45-64 year old women. Low HRs were found for hypertension among women >=75 years of age. CONCLUSIONS: In this clinical setting, CHF and cerebrovascular diseases were consistently associated with mortality in all age-groups. The possible protective effect by hypertension among elderly women should be interpreted with caution. KEY MESSAGES We found congestive heart failure and cerebrovascular diseases to be consistently associated with mortality in both women and men. We found hypertension to be associated with lower mortality risk among women >=75 years of age, although this finding must be interpreted with caution. Depression was found to be associated with increased mortality risk among men and women aged 65-74 years of age. PMID- 29172795 TI - From good to excellent: Improving clinical departments' learning climate in residency training. AB - INTRODUCTION: The improvement of clinical departments' learning climate is central to achieving high-quality residency training and patient care. However, improving the learning climate can be challenging given its complexity as a multi dimensional construct. Distinct representations of the dimensions might create different learning climate groups across departments and may require varying efforts to achieve improvement. Therefore, this study investigated: (1) whether distinct learning climate groups could be identified and (2) whether contextual factors could explain variation in departments' learning climate performance. METHODS: This study included departments that used the Dutch Residency Educational Climate Test (D-RECT) through a web-based system in 2014-2015. Latent profile analysis was used to identify learning climate groups and multilevel modeling to predict clinical departments' learning climate performance. RESULTS: The study included 1730 resident evaluations. Departments were classified into one of the four learning climate groups: substandard, adequate, good and excellent performers. The teaching status of the hospital, departments' average teaching performance and percentage of time spent on educational activities by faculty-predicted departments' learning climate performance. DISCUSSION: Clinical departments can be successfully classified into informative learning climate groups. Ideally, given informative climate grouping with potential for cross learning, the departments could embark on targeted performance improvement. PMID- 29172796 TI - Effect of orlistat or metformin in overweight and obese polycystic ovary syndrome patients with insulin resistance. AB - The aim of this study was to evaluate the effect of orlistat or metformin combined with Diane-35 on anthropometric, hormonal and metabolic parameters in overweight and obese polycystic ovary syndrome (PCOS) patients with insulin resistance (fasting insulin > 10 mIU/L). A total of 240 PCOS women were randomly allocated to orlistat plus Diane-35(OD group), metformin plus Diane-35(MD group), orlistat plus metformin plus Diane-35(OMD group) or Diane-35 (D group). Body weight, BMI, waist and hip circumference, blood pressure, endocrine profile, lipid profile and insulin resistance were assessed at baseline and after 3 months. Significant reductions in waist and hip circumference, serum LH, total testosterone and uric acid were observed in all groups compared with baseline. TG and TC significantly decreased in the OD group. Homeostasis model assessment insulin resistance (HOMA-IR) index was reduced in the OD (p = .015), MD (p = .001) and OMD (p = .004) groups. Body weight, BMI, systolic BP and HDL-C significantly changed in the OD and OMD group compared with the D group (p < .05). Side effects were less with orlistat than metformin. This study demonstrated that orlistat is more effective in reducing weight and lipid profile than metformin. Besides, orlistat has mild side-effects and is better tolerated compared with metformin. PMID- 29172797 TI - Infertility providers' and patients' views and experiences concerning doctor shopping in the USA. AB - Many questions arise concerning how infertility patients decide whether, how much and why or why not to consult more than one doctor and change physicians. To explore this issue, a total of 37 US in vitro fertilization (IVF) providers and patients were interviewed in-depth. Many infertility patients feel disappointed with infertility providers, especially after treatment failure, and then struggle to evaluate and weigh relative 'bedside manner' against technical skills, finances and hope, facing dilemmas of which doctor to choose, whether and how much, to 'shop around', how to do so, and whether and how much to give doctors 'second chances'. Complex, dynamic processes can ensue: shopping for initial or subsequent physicians and consulting and/or changing doctors multiple times, based on differing treatment approaches. Patients may alter perceptions of physicians over time. Providers are often busy and have difficulty addressing patients' emotional stresses; and may provide providing 'false hope', and/or criticize colleagues' approaches. These data, the first to explore how infertility patients decide whether, how and why to consult with more than one infertility doctor, suggest that patients may 'doctor shop,', engaging in dynamic processes, wrestling to weigh communication vs. other skills. These data have important implications for future practice, research, guidelines and education. PMID- 29172798 TI - Physiology of blood pressure relevant to managing hypertension in pregnancy. AB - PURPOSE: Pregnancy causes physiological changes in maternal organ systems, and blood pressure (BP) is one of the variables affected. This review is focusing on the physiology of BP relevant to the management of hypertension in pregnancy. MATERIALS AND METHODS: A detailed literature search was performed using electronic databases (including WorldCat, PubMed, MEDLINE, Google Scholar) to retrieve and review reports related to physiology of BP in pregnancy. RESULTS: During pregnancy, there is vasodilation caused by mediators such as increased levels of progesterone and nitric oxide. The vasodilation leads to a reduction in vascular resistance, BP, and renal blood flow. In compensation, the following postulated events occur: activation of renin-angiotensin-aldosterone axis, resetting of osmotic threshold for thirst, and an increase in the production of vasopressin. Sodium and water conservation ensue to increase the total body water, end-diastolic volume, cardiac output, and BP. The increase in cardiac output incompletely compensates for the decreased vascular resistance, and BP therefore decreases in midpregnancy and returns to prepregnancy level toward term. CONCLUSIONS: An understanding of the physiological changes in BP is essential for appropriate management of pregnancy-related hypertension. PMID- 29172799 TI - Prognostic significance of downregulated BMAL1 and upregulated Ki-67 proteins in nasopharyngeal carcinoma. AB - This study assessed the prognostic value of BMAL1 and Ki-67 expression in patients with nasopharyngeal carcinoma. Level of BMAL1 mRNA was assessed in tissue specimens from 36 nasopharyngeal carcinomas and 20 nasopharyngeal chronic inflammations using quantitative reverse transcriptase-polymerase chain reaction. Expression of BMAL1 and Ki-67 proteins was analyzed immunohistochemically in 90 paired nasopharyngeal carcinoma and distant normal tissues. The Kaplan-Meier curves and the Log-rank test were used to calculate prognostic significance stratified by BMAL1 and Ki67 protein expression and the COX regression model was to analyze the multivariate prognosis. BMAL1 mRNA was significantly reduced in nasopharyngeal carcinoma (4.67 +/- 0.27 versus 6.64 +/- 0.51 in chronic inflammation tissues, p = 0.002). Level of BMAL1 mRNA was associated with tumor distant metastasis (3.37 +/- 0.66 versus 5.04 +/- 0.27 compared with non metastasis, p = 0.011). Level of BMAL1 protein was also reduced in tumor tissues and BMAL1 expression was associated with better 1-, 3- and 5-year overall survival (OS) of cancer patients (92.6%, 69.2% and 62.3% versus 59.1%, 40.9% and 0% in patients with low BMAL1 expressed tumors; p = 0.000). BMAL1 expression and age were independent prognostic factors for OS (p = 0.032). Furthermore, Ki-67 expression was high in tumor versus normal tissues and associated with poor OS of cancer patients (p = 0.035). The Pearson correlation analysis showed that there was an inverse association between BMAL1 and Ki-67 protein expression (p = 0.021). This study demonstrated that lost BMAL1 and Ki-67 overexpression were associated with poor OS of nasopharyngeal carcinoma patients. PMID- 29172800 TI - The acceptability and effectiveness of a questionnaire for the identification of risk factors for HIV and hepatitis B and C: An observational study in general practice. AB - BACKGROUND: Many people in Europe remain undiagnosed for human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV). OBJECTIVES: To evaluate acceptability and effectiveness of a questionnaire designed to facilitate identification of risk factors for these viruses. METHODS: We performed an observational study, in a prospectively enrolled cohort of patients in Paris (France) seen in 2014. Eighteen GPs administered a questionnaire to the first 50 patients, collecting information about risk factors. GPs were randomized into two groups: A (self-administered questionnaire) and B (GP-administered questionnaire). We used the overall response rate to assess the acceptability of the questionnaire. We used the rate of newly identified risk factors and compared the number of tests performed one year before and immediately after the intervention to assess the effectiveness of the questionnaire. RESULTS: 842 patients were randomized: 349 (41.5%) in group A and 493 (58.5%) in group B. Acceptability was 88.5% (95%CI: 86.3-90.6); 93.1% (95%CI: 90.5-95.8) in-group A and 85.2% (95%CI: 82.1-88.3) in group B (P = 0.0004). Prevalence of risk factors was 51.8% (95%CI: 48.2-54.4) and 58.3% were newly identified (95%CI: 52.9-63.7). The number of HIV tests performed during the four weeks after intervention increased by 27% compared to the same period one year before (P = 0.22). It increased by 113% (P = 0.005) and 135% (P = 0.005) for HBV and HCV, respectively. CONCLUSION: The questionnaire proved acceptable and effective in identifying risk factors for HIV, HBV and HCV in general practice. PMID- 29172801 TI - The new European guideline on cardiovascular disease prevention; how to make progress in general practice? AB - The new guideline on cardiovascular disease (CVD) prevention, issued by the European Society of Cardiology was endorsed by 10 other societies, including Wonca Europe. It advices on how to reduce the cardiovascular (CV) risk in the population and attributes an important role to the general practitioner (GP). The GP is involved in treatment of the high-risk population as well as in public health measures to encourage a healthy lifestyle and CV risk factor reduction in the whole population. The new guideline gives room for a personalized approach and emphasizes that CV risk estimation and counselling need regular follow-up. We highlight the recommendations that most caught our eye and comment on the challenges for general practice.

AB - OBJECTIVE: Depression is associated with increased morbidity, mortality and hospital readmission in patients with heart failure (HF). This systematic review aimed to compile studies examining whether the use of antidepressants could improve outcome in patients with HF and concomitant depression. METHODS: The electronic libraries Embase, OVID MEDLINE(R) and PsychInfo were used to search the following terms 'heart failure' AND 'anti-depressants'; 'heart failure' AND 'TCA' OR 'SSRI' OR 'SNRI'. The result of this database search was analysed to select papers that satisfied our inclusion criteria. RESULTS: Of the 180 papers found in the original database search, only three met the inclusion criteria. A further two papers were added from hand-searching through the references. Three of these papers are randomised controlled trials (RCT); the other two, cohort studies. All studies show that antidepressants are well tolerated in this group. There was no significant difference in depressive symptoms between the test and placebo. The cardiac outcomes of patients with HF are not improved by the use of antidepressants relative to placebo. CONCLUSIONS: Antidepressants are not associated with increased mortality rate as established in previous papers. However, there is inadequate evidence that the use of antidepressants effects significant improvement in depression or cardiac outcomes. PMID- 29172803 TI - High normal blood pressure in early pregnancy also contribute to early onset preeclampsia and severe preeclampsia. AB - OBJECTIVE: This study was to evaluate effects of high normal blood pressure (HNBP) in early pregnancy on total preeclampsia, early preeclampsia, and severe preeclampsia. METHODS: We conducted a multicenter, national representative retrospective cohort study. HNBP was defined as systolic blood pressure between 130 and 140 mmHg or diastolic blood pressure between 85 and 90 mmHg. We used multivariable logistic regression to examine the associations of HNBP and the risks of above three types of preeclampsia. RESULTS: We included 58 054 women who were normotensive and nulliparous in early pregnancy. 4 809 (8.3%) fulfilled the definition of having HNBP, 16 682 (28.7%) were in normal blood pressure group, and 36 563 (63.0%) were in optimal blood pressure group. The incidence rates of total preeclampsia, early preeclampsia, and severe preeclampsia were 2.1% (1 217), 0.8% (491), and 1.4% (814), respectively. Compared to having optimal blood pressure, women with HNBP had significantly higher odds of total preeclampsia (odds ratio (OR) = 4.028, 95% confidence interval (CI) 3.377, 4.804), severe preeclampsia (OR = 3.542, 95% CI 2.851, 4.400), and early preeclampsia (OR = 8.163, 95% CI 6.219, 10.715). Our restricted cubic spline results supported the dose-response relationship between continuous blood pressure and the odds ratio of three types of preeclampsia. The fraction of early preeclampsia associated with prehypertension was 58.6%, which was higher than those of total preeclampsia (42.2%) or severe preeclampsia (40.5%). CONCLUSION: Women in early pregnancy with HNBP more likely develop total preeclampsia, early preeclampsia and severe preeclampsia, compared to those with optimal blood pressure. HNBP contribute more to early preeclampsia than severe preeclampsia. Our study provided robust epidemiological evidences for monitoring HNBP in early pregnancy to reduce the risks of preeclampsia.

AB - BACKGROUND: Maternal, cord blood and childhood adipokines have been associated with childhood obesity. We investigated whether postpartum maternal adipokines are associated with increased weight at 1 year of age in children of women with gestational diabetes (GDM). METHODS: Plasma leptin and adiponectin concentrations were measured in 160 women at approximately 12 weeks following pregnancy with GDM and compared with infant weight for length z-score at 1 year of age after adjustment for maternal and infant demographic variables. RESULTS: No association was demonstrated between maternal postpartum leptin and adiponectin concentrations and infant weight for length z-score at 1 year of age.

PMID- 29172806 TI - Hostile Attribution Bias as a Mediator of the Relationships of Psychopathy and Narcissism With Aggression. AB - Hostile attribution bias (HAB), the tendency to perceive hostility in ambiguous situations, has been linked to aggressive outcomes, such as reactive aggression. HAB has been connected to personality types involving hostile beliefs and reactive aggression, including narcissism and psychopathy. Specifically, secondary psychopathy is associated with HAB and reactive aggression. Despite research and theory connecting these constructs, few studies have examined if HAB mediates the relationships among psychopathy, narcissism, and aggression. The current study explores this possible mediation in an urban college sample. Narcissism was associated with aggression but not hostile aggression or HAB. Reactive aggression and HAB were both associated with psychopathy, but there were no mediation relationships. The associations with aggression may be, therefore, due to underlying traits of secondary psychopathy rather than the hostile attributions to which the traits contribute; consequently, treatments focused on reducing aggressive responses by correcting interpretations of social situations may not be successful. PMID- 29172807 TI - Impact of coping strategies on perceived stress, depression, and cortisol profiles among gynecologic cancer patients. AB - We explored associations between problem-focused, emotional processing, and emotional expression coping strategies and markers of stress including perceived stress, depressive symptoms, and diurnal cortisol profiles among women with gynecologic cancer. Problem-focused coping was associated with less perceived stress, fewer depressive symptoms, and more rhythmic diurnal salivary cortisol profiles. Emotional processing was associated with lower perceived stress and fewer depressive symptoms. Emotional expression was associated with fewer depressive symptoms and elevated diurnal mean and evening cortisol levels. Results point to key differences in coping strategies. In this sample, only problem-focused coping was linked with adaptive differences in both psychological and physiological stress measures. PMID- 29172808 TI - A prospective study exploring the construct and predictive validity of the COM-B model for physical activity. AB - This study examined the constructs of capability, opportunity and motivation from the COM-B model and their influence on moderate-to-vigorous physical activity. Using a prospective survey design, 186 healthy adults completed measures representing the theoretical domains framework mapped to the COM-B, and moderate to-vigorous physical activity 1 week later. The main indicators for the COM constructs were 'habits' (Capability), 'subjective norms' (Opportunity) and 'exercise self-identity' (Motivation). Motivation (77%) and moderate-to-vigorous physical activity (50%) were strongly predicted, with Capability and Motivation as key drivers of behaviour. Motivation was a strong mediator for Capability on behaviour. Future research should consider this approach for other populations and behaviours. PMID- 29172809 TI - Bridging the Gap: Racial concordance as a strategy to increase African American participation in breast cancer research. AB - Lack of African American females in breast cancer research has been receiving substantial attention. This study seeks to identify research perceptions and motivating factors needed to increase racial/ethnic minority participation in breast cancer research. A total of 57 African American women (Sigma = 47.8 years), from Rhode Island and Texas, completed a questionnaire and focus group. While many participants were not breast cancer survivors, they reported knowledge of their racial group's risk for breast cancer. One major finding that could be seen as both a facilitator and barrier is racial concordance between participant and researcher. Cultural sensitivity and trust building is recommended to increase minority participation. PMID- 29172810 TI - Perceived social support and life satisfaction in drug addicts: Self-esteem and loneliness as mediators. AB - This study was designed to investigate the mediation effects of both self-esteem and loneliness on the relationship between social support and subjective well being in drug addicts. In all, 110 participants, all drug addicts from Guangdong Fangcun Brain Hospital, completed the questionnaire. Pearson's correlation analysis showed that perceived social support was positively related to self esteem and life satisfaction and was negatively correlated with loneliness in drug addicts. Structural equation modeling estimated by the Bootstrap method indicated that loneliness and self-esteem partially mediated the association between perceived social support and life satisfaction. These findings provided insights into the association between perceived social support and life satisfaction in drug addicts. PMID- 29172811 TI - Why do they do it? Assessing self-report physical activity behavior and quality of life in individuals with multiple sclerosis. AB - Physical activity has been shown to effectively aid multiple sclerosis symptom management; however, individuals with multiple sclerosis tend to be inactive physically. Developing effective, sustainable, physical activity interventions involves first understanding motivators for physical activity. Open-ended surveys exploring physical activity motivators were collected from 215 individuals with multiple sclerosis. Responses indicate that self-efficacy and internalized motivation derived from physical activity outcomes were motivators for physical activity, and physical activity was cited as increasing overall quality of life. Future physical activity interventions should incorporate methods for building self-efficacy for physical activity and focus on increasing awareness of the long term physical benefits derived from physical activity. PMID- 29172812 TI - Validation of 'reported concussion' within a national health survey. AB - SETTING: The Canadian Community Health Survey (CCHS) is a national cross sectional health survey, which has collected information on injuries serious enough to limit normal activity. OBJECTIVE: To assess the construct and discriminant validity of reporting 'concussion or other brain injury' in the CCHS as the respondents' most serious injury. METHODS: Construct validity was assessed by describing the injury profile. Discriminant validity was assessed by examining differences between those reporting concussion or other brain injury, and either: respondents not reporting brain injury (population control); or respondents reporting orthopaedic injuries (orthopaedic control). RESULTS: In total, 1,852 of the 682,455 eligible CCHS respondents (>=12 years) reported a concussion or other brain injury within the prior year, a population annual incidence of 0.29%. Those reporting concussion or other brain injury were younger and male (p < 0.001), with an injury acquired by falling (p < 0.001) or sport or physical exercise (p < 0.001). Most (78.4%) who reported concussions or other brain injuries received medical attention from a health professional within 48 hours of their injury. The reported injury profiles appear to differ from the population controls and those reporting orthopaedic injuries. CONCLUSIONS: The report of 'concussion or other brain injury' in the CCHS may be a valid source of population-based traumatic brain injury epidemiological data. PMID- 29172813 TI - A critical scoping review of the connections between social mission and medical school admissions: BEME Guide No. 47. AB - BACKGROUND: Despite a growing focus on the social accountability of medical schools, there has been no substantive review of admissions related to the social mission of medical schools. This paper reports on a critical scoping review of the connections between social mission and medical school admissions. METHODS: Searches of seven bibliographic databases identified 1258 unique articles. After filtering for relevance, 71 articles were considered for final review. The results of the data extraction were synthesized using a combination of qualitative and quantitative techniques. RESULTS: Five reviewers conducted 149 data extractions from 71 papers. Social missions tended to focus either on access and equity issues for applicants from underrepresented populations or on the career choices of medical graduates and how they meet particular social needs. The connection between social missions and admissions was often implied but rarely considered or evaluated directly. There was a notable absence of empirical evidence, with calls for reform or program descriptions far outweighing the number of papers based on empirical findings. CONCLUSIONS: Despite the move to social missions in medical education, there remains little direct connection between missions and admissions and little evidence reflecting the efficacy or impacts of making this connection. PMID- 29172814 TI - Social media and professional identity: Pitfalls and potential. AB - INTRODUCTION: Social media developments have completely changed how information is accessed and communicated. While great potential exists with these platforms, recent reports of online unprofessional behavior by doctors has threatened the medical professional identity; a matter of critical importance for clinicians and medical educators. This paper outlines a role for social media in facilitating support for clinicians and medical teachers; it will raise awareness of pitfalls and explain ethical and legal guidelines. METHODS: An analysis of inappropriate behaviors and conflicting attitudes regarding what is acceptable in online posts, including the inter-generational contrast in online presence and perceptions of where the boundaries lie. RESULTS AND DISCUSSION: Guidance documents are analyzed and potentially confusing and conflicting statements are identified and clarified. The authors believe that clinicians and medical students must follow ethical imperatives in both personal and professional spheres. CONCLUSIONS: It is essential that medical educational and professional bodies encourage clinicians to support one another and share information online while providing clear legal and ethical advice on maintaining standards and avoiding common pitfalls. Education on the responsible use of social media and associated risk awareness should be a priority for medical school curricula. PMID- 29172815 TI - 'Modelling a Secure-Base' for Women with Complex Needs: Attachment-Based Interventions Used by Perinatal and Infant Mental Health Clinicians. AB - Infant well-being is intrinsically linked to maternal physical and emotional well being. Internationally health services have implemented policies to identify women at risk of mental health problems and developed effective care pathways. The aim of this paper is to describe how perinatal and infant mental health clinicians perceive their role and the attachment-based interventions they use in their work. The study comes from a larger mixed methods study, which examined two specialist perinatal and infant mental health services in New South Wales (Australia). Two hundred and forty-four medical records were reviewed, and six perinatal and infant mental health clinicians participated in in-depth semi structured interviews. Data were analysed by content and thematic analysis. One overarching theme, modelling a secure base and three supporting themes, enhancing reflective capacity, enhancing emotional regulation and enhancing empathy emerged from the analysis. These findings demonstrate how perinatal and infant mental health clinicians use attachment theory to inform practice by modelling "holding" and being a secure-base for women. They also provide a clearer understanding of perinatal mental health practice and can be used to inform educational programs for multidisciplinary mental health professionals particularly those working with women and infants. PMID- 29172816 TI - CT findings are highly predictive for perforation in patients with diffuse large B-cell lymphoma involving the intestines. AB - Patients with diffuse large B-cell lymphoma (DLBCL) presenting with intestinal involvement are prone to develop perforation. Identification of those who are at high risk for this complication would enable a rational-based decision regarding preemptive surgery. Although computed tomography (CT) is widely used at diagnosis, data regarding its ability to predict intestinal perforation are scanty. We performed a retrospective single-center study, including all consecutive DLBCL patients presented with intestinal involvement, assessing predictors for perforation with an emphasis on CT-related parameters. Forty-nine patients were included, 43 (88%) underwent CT scan at diagnosis. Ten patients (20%) developed intestinal perforation. A univariate regression analysis found increased risk among patients with a concentric, transmural lesion, and a longer involved intestinal segment. In conclusion, CT scan results can define patients with DLBCL and intestinal involvement who are at risk for perforation, suggesting that a preemptive surgical resection should be considered in these cases. PMID- 29172817 TI - The efficacy of problem solving therapy to reduce post stroke emotional distress in younger (18-65) stroke survivors. AB - PURPOSE: To investigate the efficacy of problem solving therapy for reducing the emotional distress experienced by younger stroke survivors. METHOD: A non randomized waitlist controlled design was used to compare outcome measures for the treatment group and a waitlist control group at baseline and post waitlist/post-therapy. After the waitlist group received problem solving therapy an analysis was completed on the pooled outcome measures at baseline, post treatment, and three-month follow-up. RESULTS: Changes on outcome measures between baseline and post-treatment (n = 13) were not significantly different between the two groups, treatment (n = 13), and the waitlist control group (n = 16) (between-subject design). The pooled data (n = 28) indicated that receiving problem solving therapy significantly reduced participants levels of depression and anxiety and increased quality of life levels from baseline to follow up (within-subject design), however, methodological limitations, such as the lack of a control group reduce the validity of this finding. CONCLUSION: The between subject results suggest that there was no significant difference between those that received problem solving therapy and a waitlist control group between baseline and post-waitlist/post-therapy. The within-subject design suggests that problem solving therapy may be beneficial for younger stroke survivors when they are given some time to learn and implement the skills into their day to day life. However, additional research with a control group is required to investigate this further. This study provides limited evidence for the provision of support groups for younger stroke survivors post stroke, however, it remains unclear about what type of support this should be. Implications for Rehabilitation Problem solving therapy is no more effective for reducing post stroke distress than a wait-list control group. Problem solving therapy may be perceived as helpful and enjoyable by younger stroke survivors. Younger stroke survivors may use the skills learnt from problem solving therapy to solve problems in their day to day lives. Younger stroke survivors may benefit from age appropriate psychological support; however, future research is needed to determine what type of support this should be. PMID- 29172818 TI - New pharmacotherapy for the treatment of glaucoma. AB - INTRODUCTION: Glaucoma is the second leading cause of blindness in the world and current pharmacotherapies for glaucoma have remained relatively unchanged (with the exception of fixed combinations of previously available medications) since the mid-1990s with the development of prostaglandin analogues. Now, with both new formulations and new classes of medications with novel mechanisms of action, the medical therapy of glaucoma may be heralding a new dawn in medical management. Areas covered: This review outlines new topical therapies for intraocular pressure (IOP) lowering treatment, in addition to new formulations, preservative free options, and advances in glaucoma medical therapy delivery. We performed a comprehensive search for published studies for glaucoma medical therapy using the electronic database PubMed. A manual search for each therapy or delivery system was also performed. Expert commentary: These advances in glaucoma therapy have the potential to overcome many barriers to glaucoma's medical care, particularly in terms of adherence. However, both time and research are needed to prove the relative efficacy and safety of these new pharmacotherapies and products, helping us decide their role in the treatment of elevated intraocular pressure. We are hopeful that these new developments in therapy may bring more options for glaucoma medical therapy. PMID- 29172819 TI - Arias-Stella Reaction With Signet Ring-Like Cell Histomorphology. AB - Cells with their nucleus pushed to the periphery in a crescent-like fashion by intracytoplasmic vacuole(s) are referred to as signet ring cells when the vacuole(s) contain mucin and signet ring-like cells when they are empty or contain a material other than mucin. Signet ring cells are commonly associated with adenocarcinomas. These cells are uncommon in the endometrium and have been found to be associated with both malignant and benign processes. We report the first case of signet ring-like cells within endometrial glands with Arias-Stella reaction. PMID- 29172821 TI - Risk of donor demise after laser therapy for twin-twin transfusion when complicated by growth discordance and abnormal umbilical artery Doppler findings. AB - OBJECTIVE: To investigate the natural course of abnormal umbilical artery Doppler (UAD) findings in donor fetuses after laser surgery and the prognostic significance of resolution, persistence, or new onset UAD abnormalities with and without the presence of preoperative growth discordance. STUDY DESIGN: Retrospective cohort study of all monochorionic-diamniotic multi-fetal gestations diagnosed with twin-twin transfusion syndrome (TTTS) undergoing laser surgery at a single large metropolitan referral center from 2010-2016. The estimated fetal weight was measured preoperatively and the UAD were measured both pre- and postoperatively (median = 8 days). Patients were grouped according to the presence of abnormal UAD with or without growth discordance pre- and postoperatively. Risk ratios (RR) were calculated for each group for risk of intrauterine fetal demise compared to the pre- and postoperative normal UAD groups as the referents. RESULTS: There were eighty-one women who met inclusion criteria throughout the study period. Forty-three (53.1%) patients had abnormal donor twin UAD preoperatively and 33 (40.7%) were diagnosed with growth discordance. However, 13 (44.8%) had normalization of the UAD postoperatively (median = 8 days) with a similar rate of donor fetal demise as the non-discordant preoperative normal UAD group (7.7% versus 10.3%, p = .79). Abnormal preoperative UAD was associated with an increased risk of donor demise (RR 3.6, CI 1.1-12.1), which was further elevated in the presence of growth discordance (RR 5.2, CI 1.7 16.3). The greatest risk for donor demise was seen if the UAD remained abnormal postoperatively with concomitant growth discordance (RR 10.3, CI 2.5-41.6). CONCLUSIONS: Preoperative abnormal donor UAD is a significant risk for donor demise post-laser therapy for TTTS. Persistent postoperative abnormal UAD with concomitant growth discordance confers the greatest risk for donor demise. However, resolution of abnormal UAD has a similar rate of donor demise when compared to patients with normal UAD preoperatively. PMID- 29172820 TI - A Sclerosing Perineurioma With Collagen Rosette Formation: Benign Mimic of Low Grade Fibromyxoid Sarcoma. AB - We report the case of a sclerosing perineurioma with conspicious collagen rosette formation in a 20-year-old male presenting with a firm, painless nodule on the palmar side of his right ring finger. The main differential diagnosis is a low grade fibromyxoid sarcoma. The distinction between these entities is important because low-grade fibromyxoid sarcoma has a metastatic potential, while, as a rule, perineuriomas are benign. The presence of collagen rosettes in this current case makes this distinction even more difficult given that approximately 30% of low-grade fibromyxoid sarcoma cases show the focal presence of collagen rosettes. The demonstration of the characteristic t(7;16), t(11;16) or t(11;22) translocations (resulting in the FUS-CREB3L2, FUS-CREB3L1 or EWSR1-CREB3L1 fusion genes, respectively) or immunoreactivity for MUC4, a recently described sensitive and specific marker for low-grade fibromyxoid sarcoma, remain the gold standard in the diagnosis of low-grade fibromyxoid sarcoma, differentiating it from perineurioma. This case is, to our knowledge, the first report on collagen rosettes in sclerosing perineurioma, extremely well mimicking low-grade fibromyxoid sarcoma, and further expanding the morphological spectrum of this rare subtype of perineurioma. PMID- 29172822 TI - Antithrombotic efficacy of bivalirudin compared to unfractionated heparin during percutaneous coronary intervention for acute coronary syndrome. AB - Bivalirudin is associated with an increased risk of acute stent thrombosis (AST) compared to unfractionated heparin (UFH) in acute coronary syndrome patients (ACS) during short-duration percutaneous coronary intervention (PCI). The mechanisms involved are unknown. We aimed to investigate the antithrombotic efficacy of bivalirudin compared to UFH during PCI. In a monocenter study, we prospectively enrolled 30 patients undergoing PCI for a non-ST elevation ACS. They were randomly assigned to a single intravenous (IV) bolus of UFH (70 IU/kg) or an IV bolus of bivalirudin 0.75 mg/kg followed by a 1.75 mg/kg/h infusion during PCI. All patients received a loading dose (LD) of 180 mg of ticagrelor at the time of PCI. The VASP index and activated partial thromboplastin time (aPTT) were used to assess the course of platelet reactivity (PR) and antithrombotic activity. The two groups were similar regarding baseline, angiographic, and interventional characteristics. There was no difference between the two groups in the course of PR following ticagrelor LD. An optimal PR inhibition was obtained 4 h after the LD of ticagrelor. The level of antithrombotic activity was significantly lower in the bivalirudin group compared to the UFH group (p < 0.001) during PCI but similar at 2 and 4 h post-PCI. We observed that, in ACS undergoing PCI, the antithrombotic efficacy of an IV bolus of bivalirudin is significantly lower than that of a 70-IU/kg UFH bolus. This could contribute to the excess in thrombotic acute events observed during short-duration PCI. PMID- 29172823 TI - Eye-tracking technology in medical education: A systematic review. AB - BACKGROUND: Eye-tracking technology is an established research tool within allied industries such as advertising, psychology and aerospace. This review aims to consolidate literature describing the evidence for use of eye-tracking as an adjunct to traditional teaching methods in medical education. METHODS: A systematic literature review was conducted in line with STORIES guidelines. A search of EMBASE, OVID MEDLINE, PsycINFO, TRIP database, and Science Direct was conducted until January 2017. Studies describing the use of eye-tracking in the training, assessment, and feedback of clinicians were included in the review. RESULTS: Thirty-three studies were included in the final qualitative synthesis. Three studies were based on the use of gaze training, three studies on the changes in gaze behavior during the learning curve, 17 studies on clinical assessment and six studies focused on the use of eye-tracking methodology as a feedback tool. The studies demonstrated feasibility and validity in the use of eye-tracking as a training and assessment method. CONCLUSIONS: Overall, eye tracking methodology has contributed significantly to the training, assessment, and feedback practices used in the clinical setting. The technology provides reliable quantitative data, which can be interpreted to give an indication of clinical skill, provide training solutions and aid in feedback and reflection. This review provides a detailed summary of evidence relating to eye-tracking methodology and its uses as a training method, changes in visual gaze behavior during the learning curve, eye-tracking methodology for proficiency assessment and its uses as a feedback tool. PMID- 29172824 TI - Aliskiren and valsartan in combination is a promising therapy for hypertensive renal injury in rats. AB - : Neither ACEI nor ARBs completely repress the RAAS. Aliskiren is a newer agent that inhibits renin. However, it increases the biosynthesis and secretion of renin and prorenin, that might induce renal tissue damage. This study was conducted to investigate the renoprotective effects of aliskiren and valsartan the ARB, either alone or in combination, on hypertensive nephropathy induced by L NAME. Aliskiren (50 mg/kg/daily i.p.), valsartan (10 mg/kg daily i.p.) alone or in half dose combination were administered with L-NAME (30-40 mg daily in drinking water) for 8 weeks. Aliskiren and valsartan significantly reduced systolic blood pressure, proteinuria, serum creatinine, blood urea nitrogen, oxidative stress, and structural renal injury although not to the same extent. Valsartan reduced systolic blood pressure and proteinuria in L-NAME treated rats more significantly than aliskiren. However, glomerular collapse index and the expansion of interstitial tissue were significantly attenuated by aliskiren than by valsartan. Cotreatment with aliskiren and valsartan markedly reduced the oxidative stress and further reduced the glomerular collapse and the expansion of interstitial tissue compared with aliskiren monotherapy. CONCLUSION: These results suggest that therapies aimed at different targets within the RAAS may have additional effects in attenuating structural injury in experimental hypertensive nephropathy. PMID- 29172826 TI - Testing Nursing Sensitive Outcomes in Out-Patient Drug Addicts, with "Nursing Role Effectiveness Model". AB - Our aim was to identify factors that contribute to a better outcome in drug users and to understand the effectiveness of nursing interventions, by applying "Nursing Role Effectiveness Model" (NREM). It's a correlational, cross-sectional study with 180 drug users in a methadone program, randomly selected from three community services. We identified that treatment time, lower co-morbidities, less poly-drug use, family support and being employed contribute to a better quality of life, better mental health, less substance addiction consequences and more satisfaction with nursing care (p < 0.05). Those data were also related with nursing interventions using Structural Equation Model and we found that nursing care contributes 29% to health outcome improvement. The model revealed itself adequate to assess the effectiveness of nursing interventions (X2: 82.51/(34) = 2.426; p < 0.01, NFI = 0.927, CFI = 0.955, RFI = 0.903, GFI = 0.917, PGFI = 0.567, PCFI = 0.722, PNFI = 0.700, RMSEA = 0.089). Compared with the NREM original model, our findings reveal new relationships between the users' structural variables and the health outcomes and also relationship between units' structural variables and nurses' structural variables. PMID- 29172825 TI - Metal load assessment in patient pulmonary lavages: towards a comprehensive mineralogical analysis including the nano-sized fraction. AB - Mineralogical analyses of clinical samples have been proved useful to identify causal relationship between exposure to airborne particles and pulmonary diseases. The most striking example is asbestosis where the assessment of asbestos bodies in patient lung samples has allowed defining values specific of pathologies. However, this type of analyses only considers the micro-sized fraction of the particles, neglecting the specific impact of nano-sized particles which have been otherwise shown to be reactive and able to induce biological effects. Similarly, in nanotoxicology, the mineralogical analysis of pulmonary fluids could be used as an indicator of exposure to inhaled nanoparticles and could help investigations on the relationship between exposure to these nanoparticles and lung diseases. We designed this study first to demonstrate the technical feasibility of this approach, then to get a clear picture of the metals present, and in what form, in patient lungs and finally to determine if indeed it is worth investigating separately the micro, sub-micro and nano fractions. Broncho-alveolar lavages were recovered from 100 patients suffering from interstitial lung diseases. A protocol was specifically developed to isolate three fractions containing respectively microparticles, sub-microparticles and nanoparticles with ions. The metal content in each fraction was qualitatively and quantitatively characterized. Results showed significant differences between the three fractions in terms of metal load confirming that the separate analysis of the fractions is relevant. It also means that the assessment of the micro-sized fraction alone, as commonly done in clinical practice, only gives a partial view of the mineralogical analysis. PMID- 29172827 TI - The prevalence of congenital malformations is still higher in pregnant women with pregestational diabetes despite near-normal HbA1c: a literature review. AB - AIMS/HYPOTHESIS: We assessed the association between congenital malformations and maternal hyperglycemia in pregnant women with pregestational (type 1 or type 2) diabetes and investigated if the rate of congenital malformations was similar in women with near-normal glycemic control compared to the background population. We also assessed the association between congenital malformations and maternal hyperglycemia in pregnant women with pregestational diabetes with special focus on women with near-normal HbA1c in early pregnancy. MATERIALS AND METHODS: This is a literature review based on an electronic literature search of the databases PubMed, Cochrane, Embase and Web of Science conducted in July 2017 using the search terms diabetes, pregnancy, HbA1c or glycemic control and congenital anomaly or congenital anomaly. We included original papers in English published after 1997 with data on congenital malformations and HbA1c in at least 250 women with pregestational diabetes. RESULTS: Nine papers with in total 6225 women with type 1 diabetes and 2334 women with type 2 diabetes were included. The prevalence of congenital malformations was 6.4% in women with type 1 diabetes and 4.3% in women with type 2 diabetes and for the combined group of women with pregestational diabetes, the relative risk compared to the background population was 3.2. In women with HbA1c < 53 mmol/mol (7.0%) in early pregnancy or HbA1c 53 64 mmol/mol (7.0-8.0%) the prevalence of congenital malformations was 4.3 and 3.7%, respectively, with a relative risk of 2.2 and 1.9, respectively. CONCLUSIONS: In pregnant women with pregestational diabetes the prevalence of congenital abnormalities was threefold higher in women with pregestational diabetes compared to the background population. However, HbA1c below 53 mmol/mol (7.0%) in early pregnancy was also associated with a two times increased risk of congenital malformations compared to the background population. PMID- 29172828 TI - Influence of adjunctive lacosamide in patients with seizures: a systematic review and meta-analysis. AB - INTRODUCTION: Adjunctive lacosamide treatment might be promising to treat seizures. However, the results remained controversial. We conducted a systematic review and meta-analysis to compare the efficacy and safety of adjunctive lacosamide versus placebo in patients with seizures. METHODS: PubMed, EMbase, Web of science, EBSCO and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of adjunctive lacosamide versus placebo on seizures were included. Two investigators independently searched articles, extracted data and assessed the quality of included studies. The primary outcomes were 50% responder rate and seizure freedom. RESULTS: Four RCTs involving 1199 patients were included in the meta-analysis. Overall, compared with placebo treatment, adjunctive lacosamide treatment was associated with a significantly increased 50% responder rate (RR = 1.89; 95% CI = 1.51-2.36; P < 0.00001) and seizure freedom (RR = 4.97; 95% CI = 1.78-13.91; P = 0.002), but improved dizziness (RR = 3.97; 95% CI = 2.91-5.42; P < 0.00001), nausea (RR = 2.85; 95% CI = 1.75-4.66; P < 0.0001), vomiting (RR = 4.11; 95% CI = 2.23-7.57; P < 0.00001), diplopia (RR = 6.85; 95% CI = 3.36-13.94; P < 0.00001), treatment emergent adverse events (RR = 2.29; 95% CI = 1.93-2.71; P < 0.00001) and serious adverse events (RR = 2.52; 95% CI = 1.33-4.78; P = 0.005). CONCLUSIONS: Compared to placebo, adjunctive lacosamide resulted in a significantly improved 50% responder rate and seizure freedom, but with increased dizziness, nausea, vomiting, diplopia, treatment-emergent adverse events and serious adverse events. PMID- 29172829 TI - Formulation and optimization of duloxetine hydrochloride buccal films: in vitro and in vivo evaluation. AB - Duloxetine hydrochloride (DH) is a serotonin-norepinephrine reuptake inhibitor (SSNRI) indicated for the treatment of depression. Duloxetine suffers from reduced oral bioavailability (~50%) due to hepatic metabolism. This study aims to develop DH buccoadhesive films to improve its bioavailability. DH buccoadhesive films were prepared adopting the solvent casting method using hydroxypropyl methylcellulose (HPMC) and polyvinyl alcohol (PVA). The prepared films were evaluated for weight uniformity, drug content, surface pH, swelling index, mucoadhesion strength and drug release percentages. Accelerated stability and bioavailability studies in healthy human volunteers were also performed for the selected films. Results of the evaluation tests showed that the optimum physicochemical characters were obtained by the films prepared with 2% HPMC using 10% propylene glycol (F2 films). Accelerated stability studies revealed that DH showed proved stability throughout the experiment time. DH bioavailability from F2 films was determined and compared with that of the marketed oral capsules (Cymbalta(r) 30 mg). The pharmacokinetic results showed that Cmax for F2 was higher than the market product. In addition, ANOVA analysis showed that a Tmax of F2 film was significantly lower, while, the AUC0-72 of F2 was significantly higher than that of Cymbalta capsules. The percentage relative bioavailability of DH from F2 was found to be 296.39%. Therefore, the prepared buccal films offer an alternative route for the administration of DH with the possibility of improving its bioavailability. PMID- 29172830 TI - Like mother like daughter: low birth weight and preeclampsia tend to reoccur at the next generation. AB - BACKGROUND: Low birth weight and preeclampsia are both adverse pregnancy and delivery outcomes, with possible influence on future health status. Previous studies have shown that intergenerational factors may be important prognostic information in evaluating women prior to or after conception. Our objective was to evaluate the role of intergenerational factors on the incidence of preeclampsia and low birth weight (LBW). METHODS: A retrospective population based study was conducted. Perinatal information was gathered from 2311 familial triads, comprising mothers (F1), daughters (F2), and children (F3). All births occurred in a tertiary medical center between 1991 and 2013. A multivariate generalized estimating equation logistic regression model analysis was used to study the association between LBW and preeclampsia across generations while controlling for confounders and for clusters of families in the database. RESULTS: A total of 1490 in F1, 1616 in F2, and 2311 in F3 were included. LBW in mothers (F2), adjusted for possible confounders, was found to be a significant predictor for LBW in offspring (OR = 1.6, 95% CI 1.02-2.6, p = .043). Likewise, preeclampsia was also noted as a significant intergenerational factor following adjustments for possible confounders (OR = 2.9, 95% CI 1.4-5.8, p = .004). CONCLUSIONS: Maternal LBW and preeclampsia are both independent risk factors for recurrence in the next generation. PMID- 29172831 TI - The placental bed vascular pathology revisited: a risk indicator for cardiovascular disease. AB - AIM: The present paper intends in the first place to clarify the confusing terminology for describing the vascular pathology of the placental bed in relation to long-term risk of cardiovascular disease. METHODS: Systematic review of relevant topics. RESULTS: The maternal blood supply to the placenta is achieved by some 100 utero-placental spiral arteries with an outside diameter varying between 200 and 600 microns. Defective physiological changes of the myometrial segment of utero-placental spiral arteries and, particularly in preeclampsia associated to hypertensive disease, the presence of atherosclerosis in their proximal segment are a cause of obstructive vascular pathology. On the other hand, basal arteries which supply the inner myometrium and basal decidua are not affected by physiological change and maintain their musculoelastic structure. They can be identified by their external diameter of less than 120 microns. Acute atherosis is an aspecific vascular lesion that occurs in basal as well as spiral arteries inside, as well as outside, the placental bed in association with a variety of obstetrical conditions. CONCLUSIONS: An increased risk of future cardiovascular disease, should be linked to atherosis or, at a later stage, atherosclerosis of utero-placental spiral arteries, rather than to that of decidual basal arteries. PMID- 29172833 TI - A systematic review of targeted agents for non-small cell lung cancer. AB - BACKGROUND: advanced-stage non-small cell lung cancer (NSCLC) is characterized by having limited treatment options and thus a poor prognosis. However, new treatment options, in the form of targeted agents (TA), have emerged during recent years. This systematic review aims to provide an overview of the accessible literature in PubMed evaluating TA used on NSCLC patients, and the resulting survival outcomes. METHOD: this systematic literature review was conducted by reviewing all relevant literature in PubMed. Six separate searches were performed: Three searches where controlled entry terms were used and three free text searches. Furthermore, other relevant publications were included manually. A total of seventy-two studies met the search criteria and were thus further analyzed and evaluated. RESULTS: In the included studies, various TAs and their effect on different molecular targets have been evaluated. Clinical responses vary considerably among the different genetic aberrations. The majority of studies evaluated TA for epidermal growth factor receptor (EGFR) mutations and TA for echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) rearrangements. Studies regarding the use of TA for Rat sarcoma (RAS), rapidly accelerated fibrosarcoma (RAF), ROS proto-oncogene 1 (ROS1) rearrangement, Receptor tyrosine-protein kinase erbB-2 (ERBB2), Phosphatidylinositol 3-kinase (PIK3CA)/v-akt murine thymoma viral oncogene homolog; protein kinase B(AKT)/Phosphatase and tensin homolog deleted on chromosome 10(PTEN), The mammalian target of rapamycin (mTOR), and Mesenchymal epithelial transition factor (MET) were included as well. In general, studies comparing treatment outcomes in EGFR-mutated patients and EML4-ALK (ALK) rearranged patients after use of either TA or standard chemotherapy, present significant better results after TA. CONCLUSIONS: This systematic review provides an overview of available literature in PubMed regarding NSCLC and TA. Included studies point toward that TA appears to be a promising therapeutic tool in treating NSCLC patients and use of TA is expected to result in improved treatment outcomes. PMID- 29172832 TI - The 17D-204 and 17DD yellow fever vaccines: an overview of major similarities and subtle differences. AB - INTRODUCTION: The yellow fever vaccine is a live attenuated virus vaccine that is considered one of the most efficient vaccines produced to date. The original 17D strain generated the substrains 17D-204 and 17DD, which are used for the current production of vaccines against yellow fever. The 17D-204 and 17DD substrains present subtle differences in their nucleotide compositions, which can potentially lead to variations in immunogenicity and reactogenicity. We will address the main changes in the immune responses induced by the 17D-204 and 17DD yellow fever vaccines and report similarities and differences between these vaccines in cellular and humoral immunity . This is a relevant issue in view of the re-emergence of yellow fever in Uganda in 2016 and in Brazil in the beginning of 2017. Areas covered: This article will be divided into 8 sections that will analyze the innate immune response, adaptive immune response, humoral response, production of cytokines, immunity in children, immunity in the elderly, gene expression and adverse reactions. Expert commentary: The 17D-204 and 17DD yellow fever vaccines present similar immunogenicity, with strong activation of the cellular and humoral immune responses. Additionally, both vaccines have similar adverse effects, which are mostly mild and thus are considered safe.

AB - INTRODUCTION: The population of patients with osteoporosis and diabetes is increasing as the aging population increases. Loss of bone mineral density occurs in patients with diabetes, but is not always a priority in the practice setting. The aim of this review is to discuss clinical considerations when managing osteoporosis in patients with diabetes. Areas covered: The pathophysiology of decreased bone mineral density in patients with diabetes is discussed. Additionally, diabetic risk factors for fracture, such as hypoglycemia, the National Osteoporosis Foundation recommendations for osteoporosis, and secondary causes of osteoporosis, including disease and medication related causes, are discussed. Furthermore, recommendations for antihyperglycemic agents, thiazolidinediones, canagliflozin, insulin, metformin, and sitagliptin are discussed due to their effects on bone mineral density. Expert opinion: Even though diabetes is an important risk factor for osteoporosis, assessing bone health in diabetic patients is often overlooked. Ensuring adequate prevention and treatment strategies for osteoporosis is vitally important with our diabetic patients as the population ages. T-scores and FRAX scores likely underrepresent a diabetic patients risk for fracture, and this should be taken into consideration in treatment decisions. Future studies are needed to determine optimal pharmacologic treatment of hyperglycemia in this population. PMID- 29172835 TI - Prevalence of hyperhomocysteinemia and its associated factors in patients with primary hypertension in Chinese urban communities: A cross-sectional study from Nanjing. AB - OBJECTIVE: This study aimed to investigate the prevalence of hyperhomocysteinemia (Hhcy) and its major determinants in Chinese urban population with new-onset hypertension. METHODS: A total of 574 adults (404 men and 170 women) with newly diagnosed primary hypertension were recruited from seven communities in Nanjing, China. Data on lifestyle factors, such as physical activities, current smoking and drinking status, dietary habits, and familial factors were collected in interviews, and laboratory examinations were performed by well-trained personnel. Potential factors related to the prevalence of Hhcy in this population were analyzed using a logistic regression model. RESULTS: Of the 574 participants, 421 (73.3%) were diagnosed with Hhcy whereas the remainder were only hypertensive. The study highlighted a number of factors that were significantly correlated (p < 0.001) with the prevalence of Hhcy. Subjects with Hhcy were more likely to be male (odds ratio [OR] 3.007, 95% confidence interval [CI] 1.781-5.079), have a smoking history (OR 1.052, 95% CI 1.031-1.074), older (OR 1.052, 95% CI 1.031 1.074), have an elevated Body Mass Index BMI (OR 1.160, 95% CI 1.080-1.246) and higher levels of low density lipoprotein cholesterol (LDL-c) (OR 1.590, 95% CI 1.226-2.063). Regular and adequate physical activity was associated with normal homocysteine levels in both male and female groups (p < 0.05). For males only, having a higher BMI, higher LDL-c or being older significantly (p < 0.05) affected the chances of Hhcy. Whereas for females, lower levels of eGFR could be related to Hhcy (p < 0.05). CONCLUSIONS: Our present study reported a high prevalence of Hhcy in the Nanjing population with new-onset hypertension. Associated factors like physical activity, gender, smoking history, age, BMI, and LDL-c were important modifiers of plasma homocysteine concentration. Management and intervention of the above associated factors should be implicated to improve H type hypertension control. PMID- 29172837 TI - Biphasic insulin aspart 30 treatment for people with type 2 diabetes: a budget impact analysis based in Thailand. AB - OBJECTIVE: To assess the financial consequences of different adoption rate of Biphasic Insulin Aspart (BIAsp) 30 instead of Biphasic Human Insulin (BHI) 30 for people with type 2 diabetes (T2DM) in Thailand from the payer's perspective. METHODS: The Excel-based International T2DM Budget Impact Model over a 3-year period was used. The cohort was the T2DM patients who received treatment from government hospitals under the Universal Health Coverage Scheme. Demographic, the adverse events, and the costs were derived from published studies in Thailand. Efficacy was based on meta-analysis. Adoption rates were assumed to increase each year. Net budget impact (NBI) and one-way sensitivity were analyzed. RESULTS: Hypoglycemia costs were lower in BIAsp 30 compared with BHI 30. The NBI per year was 26,511,269 THB (771,349 USD) for year 1, 52,181,133 THB (1,518,218 USD) for year 2, and 76,189,608 THB (2,216,747 USD) for year 3. The NBI per insulin user per year was 33.45 THB (0.97 USD), 67.27 THB (1.96 USD), 101.49 THB (2.95 USD) from year 1 to year 3, respectively Conclusions: Lower rate of hypoglycemia with BIAsp 30 than those treated with BHI 30 generates cost savings resulting in significant deduction in the additional acquisition cost of BIAsp 30. Therefore, the NBI per insulin user per year has become small. PMID- 29172836 TI - Ectonucleotidase CD39 expression in regional metastases in head and neck cancer. AB - INTRODUCTION: CD39 is the rate-limiting enzyme in the generation of immunosuppressive adenosine and its expression and activity are significant in tumor progression. Squamous cell carcinoma of the head and neck (HNSCC) shows an overall poor prognosis due to high local recurrence rates and early metastatic spread. MATERIAL AND METHODS: Primary tumor specimens and lymph node specimens harvested during neck dissection of 65 patients with a diagnosis of HNSCC were subjected to immunohistochemical and H-score analysis of CD39 expression. Demographics, histopathology and subsequent outcome were analyzed. RESULTS: The primary cancer was squamous cell carcinoma in all patients (male/female 55:10). H score for CD39 expression in the primary lesion and metastatic lymph nodes was significantly higher in advanced compared to early stages with no significant differences among different tumor locations. High intratumoral and intrametastatic CD39 expression was associated with an inferior patients' overall survival at a mean follow-up of 83.4 months (6-204 months). CONCLUSION: CD39 expression in HNSCC correlated positively with tumor stage and appears to predict poor prognosis. Therefore, CD39 expression in primary lesions and metastatic lymph nodes seems to identify patients at high risk in HNSCC of all tumor sites. Immunotherapeutic approaches targeting CD39 might be promising for this patient population. PMID- 29172838 TI - In vitro schistosomicidal activity of the lignan (-)-6,6'-dinitrohinokinin (DNHK) loaded into poly(lactic-co-glycolic acid) nanoparticles against Schistosoma mansoni. AB - CONTEXT: (-)-6,6'-Dinitrohinokinin (DNHK) display remarkable antiparasitic activity and was, therefore, incorporated into a nanoparticle formulation. OBJECTIVE: Incorporation of DNHK in poly lactic-co-glycolic acid (PLGA) nanoparticles aiming to improve its biological activities. MATERIALS AND METHODS: Synthesis, characterization and incorporation of DNHK into glycolic acid (PLGA) nanoparticles by nanoprecipitation method. The nanoparticles were characterized by ultraviolet-visible spectroscopy, X-ray diffraction, field emission electron microscopic scanning mansoni (FESEM), and dynamic light scattering (DLS). For the in vitro test with Schistosoma mansoni, the DNHK-loaded PLGA was diluted into the medium, and added at concentrations 10-200 uM to the culture medium containing one adult worm pair. The parasites were kept for 120 h and monitored every 24 h to evaluate their general condition, including: pairing, alterations in motor activity and mortality. RESULTS: The loaded PLGA nanoparticles gave an encapsulation efficiency of 42.2% and showed spherical characteristics in monodisperse polymeric matrix. The adult worm pairs were separated after 120 h of incubation for concentrations higher than 50 uM of DNHK-loaded PLGA. The groups incubated with 150 and 200 uM of DNHK-loaded PLGA for 24 and 120 h killed 100% of adult worms, afforded LC50 values of 137.0 +/- 2.12 uM and 79.01 +/- 1.90 uM, respectively, which was similar to the effect displayed by 10 uM of praziquantel. DISCUSSION AND CONCLUSIONS: The incorporation of DNHK-loaded showed schistosomicidal activity and allowed its sustained release. The loaded PLGA system can be administered intravenously, as well as it may be internalized by endocytosis by the target organisms. PMID- 29172839 TI - Assessment of evidence for nanosized titanium dioxide-generated DNA strand breaks and oxidatively damaged DNA in cells and animal models. AB - Nanosized titanium dioxide (TiO2) has been investigated in numerous studies on genotoxicity, including comet assay endpoints and oxidatively damaged DNA in cell cultures and animal models. The results have been surprisingly mixed, which might be attributed to physico-chemical differences of the tested TiO2. In the present review, we assess the role of certain methodological issues and publication bias. The analysis shows that studies on DNA strand breaks without proper assay controls or very low intra-group variation tend to show statistically significant effects. Levels of oxidatively damaged DNA, measured by the enzyme-modified comet assay, tend to show no effect in studies that have not included proper assay controls or they have uncertainty about the measurement. In addition, there are indications of publication and reporting bias. Nevertheless, the analysis shows that Aeroxide P25 generates DNA strand breaks in a concentration-dependent manner, which is not dependent on the duration of exposure. The standard comet assay seems to be able to discriminate between the genotoxicity of different types of TiO2, where anatase TiO2 seems to be the form with strongest genotoxic potential. Cell culture studies also demonstrate increased levels of oxidatively damaged DNA after exposure to TiO2. There are relatively few studies on animal models where DNA strand breaks and oxidatively damaged DNA have been tested with reliable methods. Collectively, this review shows that exposure to nanosized TiO2 is associated with genotoxicity in cells, whereas there are still too few reliable studies to assess the genotoxic potential in animal models. PMID- 29172840 TI - The influence of oral statin medications on progression of glaucomatous visual field loss: A propensity score analysis. AB - PURPOSE: The purpose of this study was to examine the association between oral statin use and the progression of open angle glaucoma. METHODS: Medical records of 847 Veterans were reviewed to collect statin use history, record demographic and comorbid medical conditions, and review visual fields. Visual field progression was judged by an ophthalmologist masked to statin use history. Progression rates in a propensity score matched cohort were compared between statin users and nonusers using McNemar's test with the propensity model derived using associated medical and demographic factors. RESULTS: The mean length of observation was 1324 days with a standard deviation of 464 days. Thirty-one per cent of Veterans demonstrated glaucomatous progression in at least one eye, 49% did not demonstrate progression, and 20% were indeterminate. Approximately 74% of subjects had previously used a statin, with this group having heavier burdens of several comorbid medical conditions and less severe baseline glaucoma than nonusers. The matched cohort was 196 statin users and 196 nonusers, each with similar baseline characteristics (standardised differences <0.10). Progression rates were 35% for statin users compared to 56% for nonusers in the matched cohort (McNemar's p<0.001). CONCLUSIONS: In this population of Veterans, glaucoma patients with any history of statin use have lower visual field progression rates than statin nonusers. PMID- 29172841 TI - Anti-inflammatory effects of Artemisia scoparia and its active constituent, 3,5 dicaffeoyl-epi-quinic acid against activated mast cells. AB - OBJECTIVES: Artemisia scoparia Waldst. et Kit. (AS) has been used to treat inflammation, urticaria and hepatitis. However, the scientific studies of AS and its active compound for inflammatory reactions in activated human mast cell line, HMC-1 cells have not yet been elucidated. MATERIALS AND METHODS: Here, we isolated 3,5-dicaffeoyl-epi-quinic acid (DEQA) from AS butanol fraction. The anti inflammatory effect of AS and its new active compound, DEQA was examined in HMC-1 cells by studying the following markers: phorbol 12-myristate 13-acetate and calcium ionophore A23187 (PMACI)-induced thymic stromal lymphopoietin (TSLP), tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta and IL-6 secretion and mRNA expression by ELISA and RT-PCR, respectively. Furthermore, mechanism related to anti-inflammatory was examined by Western blotting. RESULTS: We reported that AS and its new active compound, DEQA significantly reduced TSLP, TNF-alpha, IL 1beta and IL-6 production levels through the reduction of caspase-1 activity. The mRNA expression of these inflammatory cytokine was also reduced via blocking nuclear factor-kappaB nuclear translocation by AS and DEQA. In addition, AS significantly reduced phosphorylated-c-Jun N-terminal kinase level and DEQA significantly reduced both phosphorylated-c-Jun N-terminal kinase and -p38 mitogen-activated protein kinase levels. CONCLUSIONS: Therefore, these results indicated that AS and its active compound, DEQA may improve mast cell-mediated inflammatory diseases. PMID- 29172842 TI - Clinical Features of CMV-Associated Anterior Uveitis. AB - Cytomegalovirus (CMV) anterior uveitis is the most common ocular manifestation of CMV disease in immunocompetent individuals. It is thought to be due to a local reactivation of latent CMV and is usually unilateral. The acute form presents as Posner-Schlossman Syndrome, a recurrent hypertensive anterior uveitis with few granulomatous keratic precipitates. There are geographic differences in the chronic form of CMV anterior uveitis. Asian patients commonly present as Fuchs Uveitis Syndrome with diffuse stellate keratic precipitates, while the European patients present with a chronic hypertensive anterior uveitis with fewer keratic precipitates that are brown in color and located inferiorly. Characteristic features of CMV anterior uveitis include mild anterior chamber inflammation, elevated intraocular pressure, stromal iris atrophy. Synechiae, macular edema and retinitis are typically absent. CMV disease may also be associated with the development of corneal endotheliitis with a reduced endothelial cell count. Long term complications include glaucomatous optic neuropathy and cataract formation. PMID- 29172843 TI - Intra-articular corticosteroid injections in haemophilic arthropathy: are they recommended? AB - INTRODUCTION: Intra-articular (IA) corticosteroid (CS) injections are commonly used in the treatment of osteoarthritis. However, they are rarely utilized in haemophilic arthropathy. In fact, the efficacy of this method in haemophilic arthropathy is frequently discussed and debated in clinical practice. AIM: To investigate the effectiveness of IA CS injections in patients with painful haemophilic arthropathy. METHODS: A review of the literature on the topic was performed. RESULTS: In osteoarthritis, reports with a high level of evidence state that the efficacy of IA injections of CS is controversial. In haemophilic arthropathy, some low-level evidence reports seem to indicate that short-term pain alleviation can be achieved. CONCLUSIONS: Considering that pain relief after IA injections of CS is controversial and that the cost of the haematologic treatment required to perform the procedure is high in haemophilic arthropathy, we do not recommend the routine use of CS IS injections in haemophilia. Moreover, point of care (POC) ultrasound (US)-guided injections are not advised, because the injection procedure is so simple that the use of POC-US will unnecessarily prolong the duration of the procedure. PMID- 29172844 TI - Myopia rates in a genetically isolated population. PMID- 29172845 TI - Temporal retinal thinning and the diagnosis of Alport syndrome and Thin basement membrane nephropathy. AB - BACKGROUND AND OBJECTIVES: Alport syndrome is an inherited disease characterized by renal failure, hearing loss, and ocular abnormalities, including temporal retinal thinning. This study compared retinal thinning in Alport syndrome and other renal diseases. METHODS: Alport syndrome was diagnosed on renal biopsy and genetic testing. Subjects underwent optical coherence tomography (OCT) (Spectralis OCT, Heidelberg Instruments). Retinal thinning was determined from horizontal macular OCT scans through the foveal center using the formula: Temporal thickness index (TTI) = (nasal - temporal thickness) / nasal thickness * 100%, and compared with the normal range for each age group. Statistical analysis was performed using Student's t test, Mann-Whitney U test, and ROC analysis (SPPS, IBM). RESULTS: The mean temporal retinal thickness index was 12.4 +/- 5.2% in men (n = 19) and 7.4 +/- 1.4% in women (n = 28) with X-linked Alport syndrome; 13.1 +/- 4.5% (n = 4) in recessive disease; 6.4 +/- 2.2% (n = 5) in Thin basement membrane nephropathy; and 6.3 +/- 3.3% (n = 14) in other renal diseases. Thinning was worse in men than women with X-linked disease (p < 0.01), and worse in men who developed early onset renal failure (R2 = 0.75). Temporal retinal thinning was 84% sensitive for men with X-linked Alport syndrome and 67% specific (AUC = 0.83) compared with other renal diseases. CONCLUSIONS: Retinal temporal thinning is diagnostic for X-linked Alport syndrome in men and distinguishes them this condition from Thin basement membrane nephropathy, but only in men (p = 0.002). Temporal retinal thinning may also identify men and women with the rarer autosomal recessive disease. PMID- 29172846 TI - Use of beta blockers is associated with hearing loss. AB - OBJECTIVE: This study was conducted to investigate the hypothesis that patients using beta-blockers will develop hearing loss. DESIGN: A cross-sectional study. STUDY SAMPLE: A total of 125 patients completed the study. A total of 63 patients were on beta-blockers and 62 were not on beta-blockers. RESULTS: Carvedilol was significantly associated with hearing loss. Other beta-blockers including metoprolol and atenolol showed no association with hearing loss. Linear multiple regression analysis was run including variables of gender, age, ischaemic heart disease, cardiac failure/dilated cardiomyopathy, frusemide and carvedilol use as predictors for total hearing loss severity at all frequencies. Age and gender, as well as carvedilol, were found to be the only statistically significant predictors for hearing loss severity. CONCLUSION: Chronic use of carvedilol was associated with significant hearing loss. This may need to be taken into account when prescribing the drug. Further randomised controlled studies with baseline audiometric hearing tests before starting treatment, and periodic follow-up tests, would provide a better assessment of the effect of carvedilol on hearing.

PMID- 29172848 TI - The role of hormones in muscle hypertrophy. AB - Anabolic-androgenic steroids (AAS) and other hormones such as growth hormone (GH) and insulin-like growth factor-1 (IGF-1) have been shown to increase muscle mass in patients suffering from various diseases related to muscle atrophy. Despite known side-effects associated with supraphysiologic doses of such drugs, their anabolic effects have led to their widespread use and abuse by bodybuilders and athletes such as strength athletes seeking to improve performance and muscle mass. On the other hand, resistance training (RT) has also been shown to induce significant endogenous hormonal (testosterone (T), GH, IGF-1) elevations. Therefore, some bodybuilders employ RT protocols designed to elevate hormonal levels in order to maximize anabolic responses. In this article, we reviewed current RT protocol outcomes with and without performance enhancing drug usage. Acute RT-induced hormonal elevations seem not to be directly correlated with muscle growth. On the other hand, supplementation with AAS and other hormones might lead to supraphysiological muscle hypertrophy, especially when different compounds are combined.

PMID- 29172850 TI - Study on epidemiology of cognitive dysfunction after stroke in the population over the age of 45 in Inner Mongolia. AB - OBJECTIVE: To analyze the prevalence of different degrees vascular cognitive impairment (VCI) in stroke and the characteristics of demography distribution in Inner Mongolia. In order to provide reference data and theoretical guidance for the prevention and treatment of VCI after stroke in the area. METHODS: Stratified multi-stage random sampling was used to extract six regions of Inner Mongolia as the first sampling cluster; and then the corresponding banners (counties) were selected randomly as the secondary sampling cluster; according to the number of patient required to investigation, the corresponding number of communities was randomly selected from the secondary sampling cluster. According to the diagnostic criteria of 'Guidelines for the diagnosis and treatment of vascular cognitive impairment' and National Institute of Neurological Disorders and Stroke convened an International Workshop with support from the Association Internationale pour la Recherche et l'Enseignement en Neurosciences (NINDS AIREN), we screened all stroke patients aged 45 or older from each community, a total of 444 patients participated in the questionnaire and various scale assessments. RESULTS: The prevalence of VCI, vascular cognitive impairment no dementia and vascular dementia was 80.41%, 34.46% and 45.95% respectively. The prevalence of VCI in stroke was significantly different in different nationality, age and education level (P < 0.05), and there was no significant difference in gender, occupation, marital status and family structure (P > 0.05). CONCLUSION: The prevalence of VCI after stroke was higher in Inner Mongolia, and VCI had a relatively high morbidity in old age people and person with less education in Chinese Han population. PMID- 29172851 TI - Intrinsic subtypes and benefit from postmastectomy radiotherapy in node-positive premenopausal breast cancer patients who received adjuvant chemotherapy - results from two independent randomized trials. AB - BACKGROUND: The study of the intrinsic molecular subtypes of breast cancer has revealed differences among them in terms of prognosis and response to chemotherapy and endocrine therapy. However, the ability of intrinsic subtypes to predict benefit from adjuvant radiotherapy has only been examined in few studies. METHODS: Gene expression-based intrinsic subtyping was performed in 228 breast tumors collected from two independent post-mastectomy clinical trials (British Columbia and the Danish Breast Cancer Cooperative Group 82b trials), where pre menopausal patients with node-positive disease were randomized to adjuvant radiotherapy or not. All patients received adjuvant chemotherapy and a subgroup of patients underwent ovarian ablation. Tumors were classified into intrinsic subtypes: Luminal A, Luminal B, HER2-enriched, Basal-like and Normal-like using the research-based PAM50 classifier. RESULTS: In the British Columbia study, patients treated with radiation had an overall significant lower incidence of locoregional recurrence compared to the controls. For Luminal A tumors the risk of loco-regional recurrence was low and was further lowered by adjuvant radiation. These findings were validated in the DBCG 82b study. The individual data from the two cohorts were merged, the hazard ratio (HR) for loco-regional recurrence associated with giving radiation was 0.34 (0.19 to 0.61) overall and 0.12 (0.03 to 0.52) for Luminal A tumors. CONCLUSIONS: In both postmastectomy trials, patients with Luminal A tumors turned out to have a significant lower incidence of loco-regional recurrence when randomized to adjuvant radiotherapy, leaving no indication to omit postmastectomy adjuvant radiation in pre-menopausal high-risk patients with Luminal A tumors. It was not possible to evaluate the effect of radiotherapy among the other subtypes because of limited sample sizes. PMID- 29172852 TI - Sumoylation of the Plant Clock Transcription Factor CCA1 Suppresses DNA Binding. AB - In plants, the circadian clock regulates the expression of one-third of all transcripts and is crucial to virtually every aspect of metabolism and growth. We now establish sumoylation, a posttranslational protein modification, as a novel regulator of the key clock protein CCA1 in the model plant Arabidopsis. Dynamic sumoylation of CCA1 is observed in planta and confirmed in a heterologous expression system. To characterize how sumoylation might affect the activity of CCA1, we investigated the properties of CCA1 in a wild-type plant background in comparison with ots1 ots2, a mutant background showing increased overall levels of sumoylation. Neither the localization nor the stability of CCA1 was significantly affected. However, binding of CCA1 to a target promoter was significantly reduced in chromatin-immunoprecipitation experiments. In vitro experiments using recombinant protein revealed that reduced affinity to the cognate promoter element is a direct consequence of sumoylation of CCA1 that does not require any other factors. Combined, these results suggest sumoylation as a mechanism that tunes the DNA binding activity of the central plant clock transcription factor CCA1.

PMID- 29172854 TI - Design of composite microparticle systems based on pectin and waste material of propolis for modified l-alanyl-l-glutamine release and with immunostimulant activity. AB - Catabolic conditions like acquired immunodeficiency syndrome, cancer, and burn can cause immunosuppression. Amino acids such as alanine and glutamine are essential for the activity of the immune system. Propolis is immunostimulant and the waste of propolis extraction has been reused with technological and therapeutic purposes. Therefore, this study describes the association of propolis byproduct extract (BPE) with pectin to prepare spray-dried microparticles containing the dipeptide l-alanyl-l-glutamine as stimulant systems of neutrophils. The use of a factorial design allowed selecting the best formulation, which was characterized by morphology, size, and entrapment efficiency analyses. In addition, the systems were characterized by thermal and X ray diffraction analysis, Fourier-transform infrared spectroscopy, in vitro drug release, and in vitro cytotoxicity and stimulation test of neutrophils. Small well-structured microparticles with good entrapment efficiency values were achieved. Thermal stability of formulation was observed, and it was proved that pectin, BPE and l-alanyl-l-glutamine were dispersed throughout the matrix. The drug was released from the microparticles during 24 h governed by swelling and diffusion. The drug-loaded formulations showed a significant stimulating effect on neutrophils. These structures could increase the activity of immune cells, and other in vitro and in vivo studies should be performed in the future.

AB - INTRODUCTION: Lenalidomide has multifaceted antimyeloma properties, including direct tumoricidal and immunomodulatory effects. Several randomized controlled trials have demonstrated improved patient outcomes with lenalidomide maintenance after autologous stem cell transplant (ASCT) in patients with newly diagnosed multiple myeloma (NDMM). Currently, single-agent lenalidomide is the only approved post-ASCT maintenance therapy in the United States and European Union for patients with NDMM. Areas covered: This review article summarizes the efficacy and safety data of lenalidomide maintenance, as monotherapy and in combination with other agents, following ASCT in patients with NDMM. In addition, emerging therapies with newer agents in this setting are discussed. Expert opinion: Following ASCT, maintenance therapy with lenalidomide until progressive disease is an effective and well-tolerated regimen and represents the standard of care for patients with NDMM. Studies evaluating maintenance with lenalidomide in combination with next-generation proteasome inhibitors, monoclonal antibodies, and histone deacetylase inhibitors may further improve patient outcomes. PMID- 29172856 TI - Contextual attributes promote or hinder self-regulated learning: A qualitative study contrasting rural physicians with undergraduate learners in Japan. AB - BACKGROUND AND OBJECTIVES: Previous studies support the notion that East Asian medical students do not possess sufficient self-regulation for postgraduate clinical training. However, some East Asian physicians who are employed in geographically isolated and educationally underserved rural settings can self regulate their study during the early phase of their postgraduate career. To explore the contextual attributes that contribute to self-regulated learning (SRL), we examined the differences in self-regulation between learning as an undergraduate and in a rural context in East Asia. METHODS: We conducted interviews and diary data collection among rural physicians (n = 10) and undergraduates (n = 11) in Japan who undertook self-study of unfamiliar diseases. We analyzed three domains of Zimmerman's definition of SRL: learning behaviors, motivation, and metacognition using constructivist grounded theory. RESULTS: Rural physicians recognized their identity as unique, and as professionals with a central role of handling diseases in the local community by conducting self study. They simultaneously found themselves being at risk of providing inappropriate aid if their self-study was insufficient. They developed strategic learning strategies to cope with this high-stakes task. Undergraduates had a fear of being left behind and preferred to remain as one of the crowd with students in the same school year. Accordingly, they copied the methods of other students for self-study and used monotonous and homogeneous strategies. CONCLUSIONS: Different learning contexts do not keep East Asian learners from being self-regulated. Awareness of their unique identity leads them to view learning tasks as high stakes, and to initiate learning strategies in a self-regulated manner. Teacher centered education systems cause students to identify themselves as one of the crowd, and tasks as low-stakes, and to accordingly employ non-self-regulated strategies. PMID- 29172857 TI - Diagnostic role of cone beam computed tomography for the position of straight array. AB - OBJECTIVE: To assess the usefulness of cone beam computed tomography (CBCT) for characterizing electrode insertion and evaluate the influence of electrode insertion status on post-cochlear implantation (CI) outcomes. DESIGN: Twenty-six ears with post-CI CBCT scans were included. The devices were MED-EL Flex28 (n = 21) and Nucleus slim straight (n = 5). The parameters including cochlear duct length (CDL), insertion depth angle (IDA), insertion length of electrode (IL), and cochlear coverage (CC) were analyzed and compared with aided pure-tone threshold (PTA) with implant in free field, and open-set sentence score. RESULTS: The mean CDL was 36.8 +/- 1.4 mm. Electrode array was dislocated into scala tympani in two ears. The mean IL and IDA were 26.5 +/- 1.9 mm and 541.4 +/- 70.2 degrees . The mean linear CC (IL/CDL, 0.73 +/- 0.06) was larger than the mean angular CC (IDA/900, 0.60 +/- 0.08). The CBCT parameters showed correlation one another. While the aided pure-tone threshold was correlated with IL and IDA, there were no significant correlations in the open-set sentence score. For the postlingually deaf patients with single electrode (Flex 28), the sentence score had no significant correlation and the aided PTA was positively correlated with IL (R = 0.517, p = .028). CONCLUSIONS: This study validated the CBCT evaluating the electrode array position. The CBCT could be helpful for the preoperative selection of the optimal array and prediction of the CC. PMID- 29172859 TI - Racial/Ethnic Differences in Cigarette Use: The Roles of Mental Illness and Health-Care Access/Utilization. AB - BACKGROUND: Empirical evidence supports a hypothesis that cigarettes may be used to cope with mental illness. Little research, however, addresses how race/ethnicity is linked to mental health and cigarette use. OBJECTIVES: This study applied the self-medication hypothesis. It asked whether mental status was associated, via health-care access/utilization, with the cigarette use outcomes of four racial/ethnic groups. It also tested whether race/ethnicity moderated any such associations. METHODS: We used nationally representative data from the 2009 2010 and 2011-2012 National Health and Nutrition Examination Surveys to link cigarette use to mental status and health-care access/utilization. The final sample included 3827 White respondents, 1635 African-American respondents, 1144 Mexican-American respondents, and 781 Hispanic American (other than Mexican American) respondents. RESULTS: Consistent with earlier research and the self medication hypothesis, we observed a positive relationship between cigarette use and mental status. Associations of cigarette use and health-care access/utilization sometimes failed to take expected directions. CONCLUSIONS: We concluded from the findings that race/ethnicity's moderating role in associations between cigarette use and health-care access was generally more advantageous to Whites than other groups examined. Where treatment is delayed by lack of access to, or lack of trust in, care providers, mental health may worsen-and it is often minority Americans who lack access and trust. If minority Americans' health is to improve, shrinking racial health disparities, then access to adequate health care must be available to them, facilitating prompt treatment of mental and other illness. PMID- 29172860 TI - Washington State Spirits Privatization: How Satisfied were Liquor Purchasers Before and After, and by Type of Retail Store in 2014? AB - BACKGROUND: In 2012 Washington State ended a wholesale/retail monopoly on liquor, permitting sale of spirits in stores with > 10,000 square feet. Implementation resulted in average price increases, but also five times the stores selling liquor. OBJECTIVES: As part of a privatization evaluation, we studied pre-post and between-store-type purchase experiences. METHODS: A 2010 Washington State Liquor Control Board (LCB) survey of liquor purchasers (n = 599), and the 2014 baseline of a repeated telephone survey (1,202 residents; n = 465 purchasers), each included 10 LCB questions on satisfaction with purchase experiences, each attribute with graded response scale A = 4 to D = 1 and F (0 = fail). Analyses used t-tests for satisfaction differences by time and analysis of variance (ANOVA) for 2014 between-store satisfaction-level differences. RESULTS: Five purchase features were rated more favorably after privatization (ps < .05-.001), including product supply, staff professionalism, location convenience, store hours, and prices (though price rated lowest both times); selection offered, courtesy, and checkout speed were unaltered, and number of staff and staff knowledge declined (both p < .001). Eight consumer experiences differed by store type: five satisfaction aspects (supply, selection, number of staff, operating hours, and checkout speed) were highest for liquor superstores, while location convenience favored grocery and drug stores, and price satisfaction favored wholesale (Costco) stores, with staff knowledge highest at liquor stores. CONCLUSIONS: Satisfaction with liquor purchases increased after privatization for half the consumer experiences. Availability (location convenience and store hours) was important to liquor purchasers. Such results are relevant to sustained support for the policy of privatizing spirits retail monopolies. PMID- 29172861 TI - The benefits of sequential testing: Improved diagnostic accuracy and better outcomes for failing students. AB - INTRODUCTION: In recent decades, there has been a move towards standardized models of assessment where all students sit the same test (e.g. OSCE). By contrast, in a sequential test the examination is in two parts, a "screening" test (S1) that all candidates take, and then a second "test" (S2) which only the weaker candidates sit. This article investigates the diagnostic accuracy of this assessment design, and investigates failing students' subsequent performance under this model. METHODS: Using recent undergraduate knowledge and performance data, we compare S1 "decisions" to S2 overall pass/fail decisions to assess diagnostic accuracy in a sequential model. We also evaluate the longitudinal performance of failing students using changes in percentile ranks over a full repeated year. FINDINGS: We find a small but important improvement in diagnostic accuracy under a sequential model (of the order 2-4% of students misclassified under a traditional model). Further, after a resit year, weaker students' rankings relative to their peers improve by 20-30 percentile points. DISCUSSION: These findings provide strong empirical support for the theoretical arguments in favor of a sequential testing model of assessment, particularly that diagnostic accuracy and longitudinal assessment outcomes post-remediation for the weakest students are both improved. PMID- 29172862 TI - Comparison of Two Methods: Spinal Anesthesia and Ischiorectal Block on Post Hemorrhoidectomy Pain and Hospital Stay: A Randomized Control Trial. AB - OBJECTIVE: Hemorrhoidectomy is one of the most common hemorrhoid surgery. Many areas are innervated by nerves, and this makes the surgery to be very painful. Various anesthetic methods have been proposed, and the number of investigations and procedures demonstrated the absence of a reliable method for reducing pain. This study compares the cavity ischiorectal block with spinal anesthesia in reducing postoperative pain, analgesic consumption, and hospital stay. RESEARCH DESIGN: This study is a randomized control trial carried out on seventy patients sampled. Thirty-five (35) among them were placed in spinal anesthesia group, and the other 35 were placed in the ischiorectal block group. According to the study, questionnaire was designed in such a way that postoperative variables such as postoperative pain, analgesic consumption, changes in blood pressure, heart rate and hospital stay in both groups were evaluated and compared. CLINICAL TRIAL REGISTRATION: IRCT2015111616516N3 ( http://en.search.irct.ir/search?query=IRCT2015111616516N3 ) Results: In this study, the pain scores on Visual Analogue Scale (VAS) at 0, 6, 12, and 24 hr for spinal anesthesia group after surgery were 0, 3.08 +/- 0.78, 2.05 +/- 1.02, 1.11 +/- 0.83, respectively (p < 0.05). That of ischiorectal blocks were 0.98 +/- 0.25, 1.57 +/- 0.81, 0.91 +/- 0.91, and 0.63 +/- 0.31 respectively, which indicated lesser pain after surgery in the ischiorectal block at 6, 12, and 24 hr. In this study, out of the 35 patients that underwent spinal anesthesia, 28 patients (80%) were hospitalized in the first 6 hr, 13 patients (37.1%) in the second 6 hr, 3 patients (8.6%) in the second 12 hr after surgery. For patients under the ischiorectal block, the number of patients hospitalized were 13 patients (37.1%), in the first 6 hr, 4 patients (11.4%) in the second 6 hr, and 1 (2.9%) were hospitalized in the second 12 hr after surgery (p < 0.05). CONCLUSION: Ischiorectal blocks causes less pain, require fewer painkillers, and reduces the hospital stay after surgery than spinal anesthesia. PMID- 29172863 TI - Use of Larynx-Preservation Strategies in the Treatment of Laryngeal Cancer: American Society of Clinical Oncology Clinical Practice Guideline Update. AB - Purpose To update the guideline recommendations on the use of larynx-preservation strategies in the treatment of laryngeal cancer. Methods An Expert Panel updated the systematic review of the literature for the period from January 2005 to May 2017. Results The panel confirmed that the use of a larynx-preservation approach for appropriately selected patients does not compromise survival. No larynx preservation approach offered a survival advantage compared with total laryngectomy and adjuvant therapy as indicated. Changes were supported for the use of endoscopic surgical resection in patients with limited disease (T1, T2) and for initial total laryngectomy in patients with T4a disease or with severe pretreatment laryngeal dysfunction. New recommendations for positron emission tomography imaging for the evaluation of regional nodes after treatment and best measures for evaluating voice and swallowing function were added. Recommendations Patients with T1, T2 laryngeal cancer should be treated initially with intent to preserve the larynx by using endoscopic resection or radiation therapy, with either leading to similar outcomes. For patients with locally advanced (T3, T4) disease, organ-preservation surgery, combined chemotherapy and radiation, or radiation alone offer the potential for larynx preservation without compromising overall survival. For selected patients with extensive T3 or large T4a lesions and/or poor pretreatment laryngeal function, better survival rates and quality of life may be achieved with total laryngectomy. Patients with clinically involved regional cervical nodes (N+) who have a complete clinical and radiologic imaging response after chemoradiation do not require elective neck dissection. All patients should undergo a pretreatment baseline assessment of voice and swallowing function and receive counseling with regard to the potential impact of treatment options on voice, swallowing, and quality of life.

PMID- 29172864 TI - Management of feline tibial diaphyseal fractures using orthogonal plates performed via minimally invasive plate osteosynthesis. AB - Objectives The objective was to assess the medium- and long-term outcomes (radiographic and owner questionnaire) of feline tibial diaphyseal fractures with orthogonal plate fixation via a minimally invasive plate osteosynthesis (MIPO) approach. Methods Medical records and radiographs of cats that had tibial diaphyseal fractures stabilised with orthogonal plates were obtained (2012-2016). Immediate postoperative radiographs were reviewed to assess the construct configuration and follow-up radiographs (where available) were used to assess bone healing and implant-related complications. An owner-completed questionnaire (feline musculoskeletal pain index [FMPI]) was used at a minimum of 6 months following surgery to assess the cats' ability to perform normal activities. Results Eight feline tibial diaphyseal fractures met the inclusion criteria. One major complication was observed, most likely due to an operative technical error. There were no further complications following revision surgery. Six of the eight cases that had radiographic follow-up either had clinical bone union or showed evidence of bone healing. All cases were classified as successful according to FMPI. Conclusions and relevance Orthogonal plating of feline tibial diaphyseal fractures via an MIPO approach resulted in successful outcomes and a lower complication rate compared with previously reported techniques. PMID- 29172865 TI - MAMMOTh: A new database for curated mathematical models of biomolecular systems. AB - MOTIVATION: Living systems have a complex hierarchical organization that can be viewed as a set of dynamically interacting subsystems. Thus, to simulate the internal nature and dynamics of the entire biological system, we should use the iterative way for a model reconstruction, which is a consistent composition and combination of its elementary subsystems. In accordance with this bottom-up approach, we have developed the MAthematical Models of bioMOlecular sysTems (MAMMOTh) tool that consists of the database containing manually curated MAMMOTh fitted to the experimental data and a software tool that provides their further integration. RESULTS: The MAMMOTh database entries are organized as building blocks in a way that the model parts can be used in different combinations to describe systems with higher organizational level (metabolic pathways and/or transcription regulatory networks). The tool supports export of a single model or their combinations in SBML or Mathematica standards. The database currently contains 110 mathematical sub-models for Escherichia coli elementary subsystems (enzymatic reactions and gene expression regulatory processes) that can be combined in at least 5100 complex/sophisticated models concerning more complex biological processes as de novo nucleotide biosynthesis, aerobic/anaerobic respiration and nitrate/nitrite utilization in E. coli. All models are functionally interconnected and sufficiently complement public model resources. AVAILABILITY: http://mammoth.biomodelsgroup.ru. PMID- 29172867 TI - Substance Use in Healthcare Workers: Importance of Stress Perception, Smoking Temptation, Social Support, and Humor. AB - BACKGROUND: Research indicates healthcare workers' personal substance use may affect quality of care. Investigating factors that correlate with coping through substance use may provide insight into improving quality care. OBJECTIVES: This study aims to examine potential correlates of coping through substance use among healthcare workers, with a particular focus on humor, social support, stress perception, and smoking temptation. METHOD: Participants, recruited from healthcare facilities, anonymously completed a 30-minute questionnaire of psychometrically valid measurements. RESULTS: In a sample of primarily female (75.7%), age 20-39 (74.8%), floor staff (i.e., doctors, nurses, technicians/assistants; 61.2%), perceived stress [beta = .036, t(98) = 2.55, p = .012], smoking temptation [beta = .036, t(98) = 2.21, p = .030], and coping through humor [beta = .163, t(98) = 2.033, p = .045] were significant correlates of the coping through substance use, with all relationships positively co varying. Social support at work did not predict coping through substance use [beta = -.032, t(98) = -.814, p > .05]. Furthermore, negative affect/situation smoking temptation was associated with increased coping through substance use [beta = .246, t(99) = 2.859, p = .005] and habit/craving temptation was associated with decreased coping through substance use [beta = -.260, t(99) = 2.201, p = .030; however, positive affect/social temptation was not [beta = .054, t(99) = -.553, p > .05]. Conclusions/Importance: These findings suggest that coping with humor may relate to coping through substance use, while social support at work is either unrelated to coping through substance use in this sample or may not be adequately assessed with the measure used. Consistent with the literature, negative affect/situation was associated with increased coping through substance use. However, habit/craving was negatively predictive. Further research should explore the variables related to coping through substance use among healthcare workers. PMID- 29172868 TI - Treatment for patients with relapsed/refractory mantle cell lymphoma: European based recommendations. AB - Patients with mantle cell lymphoma (MCL) usually respond to initial combination chemotherapy, but the disease inevitably relapses and often follows an aggressive course. Here, clinical study results published since 2008 for patients with relapsed/refractory MCL were reviewed to compare available evidence for treatment guidance. Most trials identified were non-randomized, phase II studies performed at a limited number of sites, and many evaluated MCL as one of multiple non Hodgkin lymphoma subtypes. Additional randomized, comparative trials are needed. Treatment selection generally depends on patient need, age and fitness, time of relapse, and line of therapy. Combination regimens typically produce higher response rates than single agents, and adding rituximab generally improves outcomes. The inclusion of ibrutinib, lenalidomide, temsirolimus, and bortezomib, represents an important advance for patients ineligible for, unable to tolerate, or failing high-intensity combination chemotherapy. A high need for effective treatments in relapsed/refractory MCL remains, particularly for elderly and frail patients. PMID- 29172866 TI - Radiosensitization of ultrasmall GNP-PEG-cRGDfK in ALTS1C1 exposed to therapeutic protons and kilovoltage and megavoltage photons. AB - PURPOSE: One of the promising radiosensitizers is the ultrasmall gold nanoparticle (GNP) with a hydrodynamic diameter <3 nm. We studied functionalized ultrasmall GNPs (1.8 nm diameter) coated by polyethylene glycol (PEG) and conjugated with cyclic RGDfK (2.6 nm hydrodynamic diameter) for targeting of alpha(v) beta(3) integrin (alphavbeta3) in the murine ALTS1C1 glioma cell line. MATERIALS AND METHODS: We investigated the uptake, toxicity and radiosensitivity of GNP-PEG-cRGDfKs in ALTS1C1 cells exposed to protons, kilovoltage photons and megavoltage photons. The in vitro uptake and toxicity of GNPs in the hepatocytes and Kupffer cells were assessed for murine AML12 hepatocyte and RAW 264.7 macrophage cell lines. The in vivo biodistribution of GNPs in the ALTS1C1 tumor model was tested using the inductively coupled plasma mass spectrometry. RESULTS: Results indicated GNPs accumulated in the cytoplasm with negligible toxicity for a moderate concentration of GNPs. Observed sensitizer enhancement ratios and dose enhancement factors are 1.21-1.66 and 1.14-1.33, respectively, for all radiations. CONCLUSION: Ultrasmall GNP-PEG-cRGD can be considered as a radiosensitizer. For radiotherapy applications, the delivery method should be developed to increase the GNP uptake in the tumor and decrease the uptakes in undesirable organs. PMID- 29172869 TI - Relationship between Tobacco Craving and Quality of Life among French Students: Results of a Cross-Sectional Study. AB - BACKGROUND: Understanding the factors leading to smoking cessation is of primary importance in reducing the death burden. Recently introduced in the DSM-5, craving is a potentially promising mechanism involved in relapse, but its articulation with quality of life and deprivation on tobacco student's consumers has never been investigated. OBJECTIVES: Our study explores the relationship between tobacco craving and sub-dimensions of quality of life when controlling effect of deprivation on a youth population with tobacco consumption. METHOD: Comparison between deprived and non-deprived students were conducted with online questionnaires on demographic data, level of dependency, perceived quality of life, deprivation and craving. Multivariate linear regression with backward procedure was conducted to assess the predictive validity of these variables on craving. Finally, Bayesian analysis was conducted to evaluate the model proposed by the regression. RESULTS: One hundred and seventy-four participants were included. Craving was significantly correlated with all the other variables and increases when the level of deprivation rises, while it decreases when physical health improves. These results are confirmed by Bayesian linear regression. Conclusions/Importance: Environmental and social factors are usually overlooked when it comes to understanding individuals, deeply rooted biological mechanisms such as craving. Working on physical health is of interest to diminished craving and improves the quality of life during smoking cessation and thereby to support success on the student population. Consequences for the triadic neurocognitive model of addiction are discussed. PMID- 29172870 TI - Identifying Risk Factors for Drug Use in an Iranian Treatment Sample: A Prediction Approach Using Decision Trees. AB - INTRODUCTION AND AIM: Substance abuse exacts considerable social and health care burdens throughout the world. The aim of this study was to create a prediction model to better identify risk factors for drug use. DESIGN AND METHODS: A prospective cross-sectional study was conducted in South Khorasan Province, Iran. Of the total of 678 eligible subjects, 70% (n: 474) were randomly selected to provide a training set for constructing decision tree and multiple logistic regression (MLR) models. The remaining 30% (n: 204) were employed in a holdout sample to test the performance of the decision tree and MLR models. Predictive performance of different models was analyzed by the receiver operating characteristic (ROC) curve using the testing set. Independent variables were selected from demographic characteristics and history of drug use. RESULTS: For the decision tree model, the sensitivity and specificity for identifying people at risk for drug abuse were 66% and 75%, respectively, while the MLR model was somewhat less effective at 60% and 73%. Key independent variables in the analyses included first substance experience, age at first drug use, age, place of residence, history of cigarette use, and occupational and marital status. DISCUSSION AND CONCLUSION: While study findings are exploratory and lack generalizability they do suggest that the decision tree model holds promise as an effective classification approach for identifying risk factors for drug use. Convergent with prior research in Western contexts is that age of drug use initiation was a critical factor predicting a substance use disorder. PMID- 29172872 TI - Ultrasonography in the diagnosis and management of cats with ureteral obstruction. AB - Objectives The objective was to identify clinical or ultrasonographic results associated with ureteral obstruction or outcome in cats with azotaemia. Methods This was a retrospective cross-sectional study of cats with azotaemia (serum creatinine >180 MUmol/l) that had ultrasonography of the urinary tract, ultrasound images available for review and received treatment for azotaemia. Cats with pre-renal azotaemia or urethral obstruction were excluded. Associations between clinical and ultrasonographic results and the dependent variables 'tentative diagnosis of ureteral obstruction', 'pyelography positive for ureteral obstruction' and 'death in hospital' were tested using binary logistic regression. Results In total, 238 cats satisfied the inclusion criteria. Median age was 7 years (range 2 weeks to 20 years), duration of clinical signs was 7 days (range 1 day to 6.3 years) and serum creatinine was 417 MUmol/l (range 184 2100 MUmol/l). Tentative diagnosis of ureteral obstruction in 92/238 (39%) cats was significantly associated with unilateral enlarged kidney on palpation, and dilated renal pelvis and calculi within the ureter on ultrasonography. Pyelography was performed in 49/92 (53%) cats (16 bilateral) with a tentative diagnosis of ureteral obstruction, and was positive for obstruction in 46/65 (71%) instances. No significant differences in ultrasonographic signs were found between cats with obstructed and non-obstructed ureters. Receiver-operating characteristic analysis of renal pelvic diameter as a diagnostic test for ureteral obstruction found an area under the curve not significantly different from 0.5. There was good agreement between results of radiography and ultrasonography for presence of urinary calculi (kappa 0.67). Treatment was medical in 171 (72%) cats and surgical (ureteral stent or by-pass device) in 67 (28%). Death in hospital was significantly associated with serum creatinine and presence of peritoneal fluid, but not with clinical diagnosis, ultrasonographic signs or treatment method. Conclusions and relevance Ultrasonography may be used to identify azotaemic cats at greatest risk of ureteral obstruction, but when using pyelography as the reference test ultrasonography appears to be inaccurate for diagnosis of ureteral obstruction. PMID- 29172871 TI - Repeated Measures Analysis of Alcohol Patterns among Gay and Bisexual Men in the Momentum Health Study. AB - BACKGROUND: This study analyzed repeated study visits (n = 2,624) of 693 gay and bisexual men (GBM) in the Momentum Health Study from July, 2012 to June, 2015. Based on recent cross-sectional analyses, we hypothesized that over the study period: (1) hazardous drinking levels would remain high, (2) GBM classified as Hazardous Drinkers will be consistently associated with high risk sex, and (3) GBM classified as Always Hazardous Drinkers differ significantly from Sometimes Hazardous Drinkers. METHODS: AUDIT classified participants as Non-Hazardous Drinkers or Hazardous Drinkers, the Cochran-Mantel-Haenszel Test assessed hazardous drinking trends, and Generalized Estimating Equations (GEE) analysis identified Hazardous Drinking covariates. Logistic regression analysis of participants with at least two study visits (575) compared those who were Sometimes Hazardous Drinkers (n = 171) with Always Hazardous Drinkers (n = 129). RESULTS: At baseline 40% of participants were Hazardous Drinkers, but there was a significant decline in hazardous drinking by visit and Hazardous Drinkers were not significantly associated with high risk sex. Always Hazardous Drinkers had significantly more high risk sex and gay bar attendance, but less often sought Internet sex partners compared to Sometimes Hazardous Drinkers. CONCLUSIONS: Analyses did not support the first two hypotheses, but distinguishing between Always and Sometimes Hazardous drinkers identified a young GBM subgroup associated with significantly higher levels of high risk sex and social support measures. These results suggest interventions programs based on Social Norms Theory, which predicts peer norms among youth are important factors in regulating drinking patterns, may be effective for these men. PMID- 29172873 TI - Retrospective evaluation of toceranib phosphate (Palladia) use in cats with mast cell neoplasia. AB - Objectives The purpose of this study was to solicit and compile data from practicing veterinary specialists regarding their use of toceranib in cats with mast cell neoplasia and to provide initial assessment of possible clinical benefit and adverse events. Methods The American College of Veterinary Internal Medicine and Oncology listservs were used to solicit data pertaining to cases in which toceranib was used in the treatment of feline mast cell neoplasia. Cases were included if the following data were received: signalment (age, sex, breed), diagnosis of mast cell neoplasia by either cytology or histopathology, anatomic classification of disease (cutaneous, splenic/hepatic, gastrointestinal, other), previous and concurrent treatment, toceranib dose (mg/kg) and schedule, duration of therapy, best response and documentation of adverse events. Results Case data from 50 cats with cutaneous (n = 22), splenic/hepatic (visceral) (n = 10), gastrointestinal (n = 17) or other (n = 1) mast cell neoplasia were received. Clinical benefit was seen in 80% (40/50), including 86% (19/22) with cutaneous, 80% (8/10) with visceral and 76% (13/17) with gastrointestinal involvement. A majority of cats (n = 35) received glucocorticoids during toceranib treatment. Median duration of treatment in cats experiencing clinical benefit was 36 weeks (range 4-106 weeks), 48 weeks (range 12-199 weeks) and 23 weeks (range 13-81 weeks) for cutaneous, visceral and gastrointestinal cases, respectively. Toceranib was administered at a median dose of 2.5 mg/kg (range 1.6-3.5 mg/kg); in 90% (45/50) the drug was given three times per week. Treatment was generally well tolerated with 60% (30/50) of cats experiencing adverse events. The majority of these events were low-grade (grade 1 or 2) gastrointestinal or hematologic events that resolved with treatment break and/or dose adjustment. Conclusions and relevance Toceranib appears to be well tolerated in feline patients with mast cell neoplasia. Biologic activity of this drug is evident in the studied cats; however, further prospective studies are needed to elucidate fully its role in treatment of this disease. PMID- 29172875 TI - Consider the eye in preventive healthcare - ocular findings, intraocular pressure and Schirmer tear test in ageing cats. AB - OBJECTIVES: Geriatric health screening in cats is highly recommended. However, information about normal and abnormal findings is scarce, especially regarding the eyes of ageing cats. This prospective study examined the influence of the ageing process on vision and ocular structures in older cats. METHODS: A total of 209 cats (aged 9-24 years) underwent physical examination, vision assessment, slit lamp biomicroscopy and ophthalmoscopy. Systolic blood pressure (SBP) measurement, Schirmer tear test (STT) reading and rebound tonometry were performed. Systemic disease was not a criterion for exclusion. RESULTS: Vision was good in 157/209 cats (75.1%) and impaired in 52/209 cats (24.9%). Increasing age and the occurrence of vision impairment were not statistically associated ( P = 0.053). Retinal oedema, retinal haemorrhage and/or retinal detachment (19 cats) and glaucoma (12 cats) were the most common findings in vision impaired cats. Increasing age was significantly associated with the occurrence of lenticular sclerosis ( P = 0.01) and attenuated retinal vessels ( P = 0.02). Increasing age and SBP were significantly associated with the occurrence of retinal detachment, haemorrhage and oedema ( P <0.001 each). In cats without evidence of hypertensive ocular damage, younger cats had a tendency for higher SBP values than older cats, although this difference was not significant. Mean intraocular pressure (IOP) was 16.5 +/- 5.0 mmHg. Age did not significantly affect the IOP values ( P = 0.54). Mean STT was 15.8 +/- 4.8 mm/min. The STT was found to increase with age ( P = 0.025). CONCLUSIONS AND RELEVANCE: Although vision impairment is not a clinical sign of old age in cats, age-related changes may contribute to vision-threatening diseases. This study contributes to preventive healthcare by examining the influence of the ageing process on vision and ocular structures in older cats.

AB - Sepsis-induced immunosuppression increases the risk of chronic infection and reduces survival. Myeloid-derived suppressor cells (MDSCs) expand in the bone marrow and spleen during murine polymicrobial sepsis, contributing to immunosuppression. A better understanding of molecular controls of MDSC production is needed to identify treatment targets. We previously reported that miR-21 and miR-181b couple with transcription factor NFI-A to induce MDSCs during murine sepsis. Here, we expand upon these observations by showing that conditional deletion of the Nfia gene in the myeloid lineage precludes MDSC development. NFI-A-deficient Gr1+CD11b+ myeloid cells are not immunosuppressive and differentiate normally into macrophages and dendritic cells. In contrast, ectopically expressed NFI-A prevents differentiation of these immature Gr1+CD11b+ cells, while converting them into MDSCs. In addition, NFI-A-deficient Gr1+CD11b+ cells decreased, and cells transfected with NFI-A increase expression of miR-21 and miR181b. Our results support a myeloid cell loop in which NFI-A and miR-21 and miR-181b sustain Gr1+CD11b+ MDSC-dependent immunosuppression during sepsis. PMID- 29172876 TI - Limbal Stem Cell Transplantation and Complications. AB - Corneal epithelial stem cells are adult somatic stem cells located at the limbus and represent the ultimate source of transparent corneal epithelium. When these limbal stem cells become dysfunctional or deficient, limbal stem cell deficiency (LSCD) develops. LSCD is a major cause of corneal scarring and is particularly prevalent in chemical and thermal burns of the ocular surface. LSCD leads to conjunctivalization of the corneal surface, neovascularization, recurrent or persistent epithelial defects, ocular surface inflammation, and scarring that, in turn, lead to decreased vision, pain, and impaired quality of life. Several techniques have been reported for limbal stem cell transplantation (LSCT). We introduce the surgical techniques, examine the success rate, and discuss the postoperative complications of conjunctival limbal autograft (CLAU), cultivated limbal stem cell transplantation (CLET), simple limbal epithelial transplantation (SLET), and limbal allograft, including keratolimbal allografts (KLAL) and living related conjunctival allograft (LR-CLAL). PMID- 29172877 TI - Frequent Drug Use and Negative Employment Outcomes among the Criminally Active. AB - BACKGROUND: Employment is a central component of economic independence and is widely viewed as an essential element of social control. Whether frequent drug use reduces the likelihood of employment or obstructs hours worked, wages, and job commitment is therefore an important question about which there remains uncertainty. METHODS: We improve on shortcomings of prior research through a monthly within-person analysis of a population at high-risk of both drug use and poor employment outcomes. We present multilevel models of the 18 months spent on the street preceding the arrest that led to incarceration in minimum/medium security facilities in Ohio from a random sample of 250 adult male inmates interviewed during the outset of a prison spell. RESULTS: The analysis reveals consistently strong, negative effects of frequent drug use on employment, hours worked, and wages in the month following frequent drug use, including marijuana, cocaine, heroin, and prescription opioids. As well, frequent drug use (with the exception of marijuana) undermines job commitment during the months that participants are employed. CONCLUSIONS: The consequences of frequent drug use for future employment are consistently negative within this criminal justice sample. Results suggest that lower levels of drug use may improve the success of postrelease employment programs. In a context of increasing concern over rising opioid and heroin, but also cocaine and marijuana abuse, the findings suggest a renewed focus on and perhaps expansion of evidence-based drug treatment among populations embedded within the criminal justice system, particularly if employment constrains criminal behavior. PMID- 29172878 TI - The economic evidence for advanced imaging in the diagnosis of suspected scaphoid fractures: systematic review of evidence. AB - Given the limitations of conventional radiography in the diagnosis of suspected scaphoid fractures on presentation, advanced imaging, particularly magnetic resonance imaging, is a useful additional investigation. We carried out a systematic review of the economic evidence for the use of advanced imaging in the management of suspected scaphoid fractures. Fifteen articles were included in the review. Owing to the heterogeneity of study designs, the type and timing of interventions and the economic analyses performed, direct comparisons between the 15 studies were difficult. From a health care perspective, little could be concluded regarding the economic implications of the use of advanced imaging in clinical practice. However, from a societal perspective, the evidence favours the use of advanced imaging in the management of suspected scaphoid fractures as it does appear to lead to overall cost-savings. PMID- 29172879 TI - Circadian Rhythms in Visual Responsiveness in the Behaviorally Arrhythmic Drosophila Clock Mutant ClkJrk. AB - An organism's biological day is characterized by a pattern of anticipatory physiological and behavioral changes that are governed by circadian clocks to align with the 24-h cycling environment. Here, we used flash electroretinograms (ERGs) and steady-state visually evoked potentials (SSVEPs) to examine how visual responsiveness in wild-type Drosophila melanogaster and the circadian clock mutant ClkJrk varies over circadian time. We show that the ERG parameters of wild type flies vary over the circadian day, with a higher luminance response during the subjective night. The SSVEP response that assesses contrast sensitivity also showed a time-of-day dependence, including 2 prominent peaks within a 24-h period and a maximal response at the end of the subjective day, indicating a tradeoff between luminance and contrast sensitivity. Moreover, the behaviorally arrhythmic ClkJrk mutants maintained a circadian profile in both luminance and contrast sensitivity, but unlike the wild-types, which show bimodal profiles in their visual response, ClkJrk flies show a weakening of the bimodal character, with visual responsiveness tending to peak once a day. We conclude that the ClkJrk mutation mainly affects 1 of 2 functionally coupled oscillators and that the visual system is partially separated from the locomotor circadian circuits that drive bouts of morning and evening activity. As light exposure is a major mechanism for entrainment, our work suggests that a detailed temporal analysis of electrophysiological responses is warranted to better identify the time window at which circadian rhythms are most receptive to light-induced phase shifting. PMID- 29172880 TI - Spiritual Struggles and Problem Drinking: Are Younger Adults at Greater Risk than Older Adults? AB - BACKGROUND: Although a good deal of research has assessed the positive effects that involvement in religion has on alcohol use, there is relatively little research on the negative aspects of religious life and alcohol problems. OBJECTIVES: This study has two objectives. The first is to see if spiritual struggles are associated with problem drinking. The second is to see if the relationship between spiritual struggles and problem drinking is stronger for younger than for older adults. METHODS: The data come from a recent nationwide survey of adults of all ages who reside in the United States (N = 2142).The study was conducted in 2014. Problem drinking is assessed with the CAGE questionnaire. RESULTS: The findings indicate that people who encounter more spiritual struggles are more likely to experience problem drinking. The relationship between spiritual struggles and problem drinking was stronger than the relationship between three other frequently used measures of religion and problem drinking (i.e., attendance at worship services, private prayer, and affiliation with Evangelical denominations). The results further reveal that spiritual struggles are associated with a greater risk of drinking problems among younger than among older individuals. Conclusions/Importance: Although many studies show that various facets of religion are associated with a lower risk of experiencing problems with alcohol the findings from the current study show that there are negative aspects of religious life that may be associated with a greater risk of having problems with alcohol. PMID- 29172881 TI - The Institute of Medicine recommendation for gestational weight gain is probably not optimal among non-American pregnant women: a retrospective study from China. AB - PURPOSE: To investigate whether the Institute of Medicine (IOM) recommended gestational weight gain (GWG) range is optimal among Chinese singleton pregnant women. METHODS: For the purpose of a retrospective observational study, data on 8209 mature singleton deliveries in Shanghai from January 2014 to December 2016 were extracted from medical records in terms of clinical performance. All cases were categorized as undergainers, appropriate-gainers, and above-gainers according to IOM recommended gestational weight gain range after stratification of maternal BMI and proportions of three categories were calculated. Comparisons of maternal and neonatal outcome were conducted among three categories and the associations of those outcome including risks of low birth weight (LBW) and macrosomia (MAC) with GWG were estimated by logistic regression analysis. To examine the applicability of IOM recommendation for Chinese pregnant women, the accumulated risk of LBW and MAC was displayed by stacked column chart and comparison was made among GWG category. The joint predicted risk (JPR) curve of both LBW and MAC in relation to GWG (continuous measurement) was plotted to demonstrate the relation of lowest JPR corresponding GWG with IOM range. RESULTS: The IOM recommended weight gain was achieved only by 3502 (42.7%) pregnant women and 41.6% gained excessive weight during pregnancy, especially for the overweight and obese women, the proportions of above-gainers mounting to 65.7 and 75.9%, respectively. By multivariate analysis GWG significantly influenced the risk of MAC and caesarean section. Although the association between the risk of LBW and GWG was not significant, p value reached .051. The risk of delivering macrosomia and caesarean section doubled when GWG exceeded the IOM rang. Appropriate gainers did not always gain the lowest joint risk of low birth weight and macrosomia from stacked column chart and it is obvious that the GWG point according to the lowest JPR was always located left to the IOM recommended range for each BMI category from the JPR curve chart in relation to GWG. CONCLUSIONS: The IOM recommended GWG range is possibly too much for Chinese singleton pregnant population for each BMI category. It is necessary to build different gestational weight gain standards for specific ethnic population.

AB - We investigated the effects of feeding vitamin C (Vit C) during neonatal and juvenile growth on learning and memory of rats. Rats after delivery were randomly divided into four groups and treated. Group 1, control group, received normal drinking water. Groups 2-4 received Vit C 10, 100, and 500 mg/kg, respectively, from the first day. After 8 weeks, 10 male offspring of each group were randomly selected and tested in the Morris water maze (MWM) and passive avoidance (PA) tests. Finally, the brains were removed for biochemical measurement. In MWM, 10 500 mg/kg Vit C reduced the latency and traveled distance and increased time spent in the target quadrant. In PA, 10 and 100 mg/kg of Vit C increased the latency; 10-500 mg/kg of Vit C decreased the malondialdehyde (MDA) in the brain tissues and increased thiol and catalase (CAT) activity compared to the control group. We showed that feeding rats Vit C during neonatal and juvenile growth has positive effects on learning and memory. PMID- 29172883 TI - Prevalence & correlates of chronic perinatal pain - a study from India. AB - OBJECTIVES: To study the prevalence of chronic perinatal pain among mothers who had infants between the ages of 13-25 months in the State of Kerala, India and to report its correlates in the socio-demographic, obstetric and psychological domains. METHODS: A total of 9305 mothers selected by cluster random sampling were assessed cross-sectionally for chronic perinatal pain using a questionnaire by Junior Public Health Nurses (JPHNs). In addition, information regarding socio demographic profile, obstetric history, infant details and perinatal depression were collected. RESULTS: Of the 8302 (89.3%) valid responses, 552 (6.6%) mothers reported chronic perinatal pain. Among those with pain, 142 (25.6%) reported pain during pregnancy, 314 (56.7%) during postpartum and 96 (17.7%) during both periods. The commonest sites of pain reported were back 280 (51%) and pelvic region 110 (19%). Mothers with chronic perinatal pain were more likely to be younger, less educated, employed and from an urban background. Chronic perinatal pain was associated with obstetric complications, delivery by instrumental/caesarean section, non-exclusive breast feeding and higher maternal depression scores. CONCLUSION: Chronic pain is common among mothers in India during the perinatal period and greater attention needs to be given for it to be recognised and treated early. PMID- 29172884 TI - Social technology: helping or hindering communication in care? PMID- 29172885 TI - What influences palliative care nurses in their choice to engage in or decline clinical supervision? AB - BACKGROUND: Clinical supervision (CS) has been around since the early 1990s in the UK and has been endorsed by government and professional bodies. Levels of engagement range from 18% to 85%. AIM: To investigate what influences palliative care nurses in their choice to engage in or decline clinical supervision. METHOD: A qualitative study was undertaken in an inpatient hospice in England and employed two focus groups to compare the views of participants and non participants in CS. Data were audio recorded and transcribed verbatim by the researchers and analysed using systematic text condensation. FINDINGS: Palliative care nurses all used informal team support for 'in the moment' support. Some engaged in formal CS to reflect 'on action' and to challenge practice. Nurses reported a lack of clarity regarding CS but, once this was overcome and engagement with CS was established, it led to changes in practice, identification of training needs and team building. The option of choice between group and individual supervision was found to be important. Group supervision led to enhanced understanding of group members which also led to team building, individual sessions were useful for individual issues. Protected time was essential for staff to be able to engage in CS. Staff who worked in larger teams reported higher levels of engagement, whereas a small team reported less need due to more informal team support. CONCLUSION: These findings are positive as they illuminate the importance of choice for support. Nurses need to be aware of their options for support and ultimately how this support affects the care they provide. The Palliative Care Nurse's Model of Support was developed, which shows the effects of each choice and how this may lead to team-building. PMID- 29172886 TI - Research roundup.

PMID- 29172887 TI - Predicting hospital transfers among nursing home residents in the last months of life. AB - BACKGROUND: Concerns have been raised over the practice of transferring nursing home residents to hospital at their end of life. OBJECTIVE: To examine the family and facility factors that may influence the decision to transfer nursing home residents to hospital in the last month of life. RESEARCH DESIGN: Secondary data analysis includes a sample of 119 bereaved family members from 21 nursing homes located in Central Canada. METHOD: A binary logistic regression analysis was conducted to explore the predictors for hospital transfers. RESULTS: Terminal hospital transfers were common: 70% of nursing home residents were sent to hospitals in the last month of their life, and the likelihood of terminal hospital transfers increased by having an adult child as decision-maker (odds ratio (OR) = 5.03; 95% confidence interval (CI) = 1.6, 16; significance level/probability value (p) = 0.007) or having a lower family income (OR = 2.9; 95% CI =1.1, 2.9; p = 0.027). Discussion and implications: The identified predictors for terminal hospital transfers are helpful in targeting and developing interventions to improve end-of-life care. Particular emphasis should therefore be placed on targeting families with low income and children of the nursing home residents for educational initiatives such as advance care planning awareness, in order to prevent terminal hospital transfers. It is hoped that policy-makers and practitioners can start addressing the findings of this study to reduce terminal hospital transfers at end of life and promote quality end-of life care in nursing homes. PMID- 29172888 TI - Corrigendum. PMID- 29172889 TI - Communication disorders in palliative care: investigating the views, attitudes and beliefs of speech and language therapists. AB - AIM: Speech and language therapists (SLTs) provide intervention for communication and swallowing to patients with life-limiting conditions, such as dementia and head and neck cancer. The role of the SLT in palliative care is difficult to define. Much is known about the clinical aspects of this role; however, little is known about the core values, beliefs and expectations of SLTs working in this sector, particularly with regard to their role in supporting patients' communication. Through a series of semi-structured interviews and a follow-up focus group, this report aimed to form a picture of the experiences and views of SLTs about their communication role in palliative care. Results suggest that SLTs are forging a self-identity in a sector that is itself constantly evolving, which causes difficulties in defining their role. Participants report that other health professionals have a poor understanding of the SLT's role. SLTs may benefit from palliative care-specific guidelines and increased interprofessional awareness of their role in order to become better integrated into the palliative care sector. PMID- 29172890 TI - Challenges to advance care planning among multidisciplinary health professionals in China. AB - BACKGROUND: Advance care planning (ACP) is a critical component of quality end-of life care. Little is known regarding the cultural influences on health professionals' attitudes toward the discussion of ACP in China. OBJECTIVE: To better understand attitudes toward ACP among Chinese healthcare professionals in China and the influence of cultural factors such as filial piety, or xiao. METHODS: A mixed methods study was used. This study reports the results of a descriptive cross-sectional survey of physicians, nurses and social workers with experience in palliative and end-of-life care. RESULTS: Some 102 completed surveys were obtained. Most Chinese health professionals had an overall positive attitude toward ACP, acknowledging that these discussions should occur. However, there was a general lack of confidence and sense of reluctance among participants to engage in ACP discussions. CONCLUSION: The lack of statistical difference between the various health professionals suggests that they all faced challenges in participating in ACP discussions. Future research should focus on the influences of cultural factors such as xiao on ACP discussion, and develop culturally sensitive strategies to facilitate these discussions in the Chinese community.

PMID- 29172892 TI - Attitudes of nurses towards care of the dying patient in India. AB - BACKGROUND: Worldwide, end-of-life care is coming under increasing scrutiny as nurses struggle to balance cultural norms and legal requirements with the desires of patients and families. The purpose of this descriptive pilot study was to examine and describe nurses' attitudes when caring for dying patients in India, and whether participation in an educational conference, which included two scenario-based, low-fidelity simulations increased knowledge of end-of-life care. METHOD: Participants' attitudes were measured with the 30-item Frommelt Attitudes Toward Care of the Dying (FATCOD-B) scale. Knowledge was measured with a researcher-developed 15-item content-focused test before and after the conference. RESULTS: The mean attitude scores of nurses (n=101) were M=101.45 (range 65-143, SD=15.99). Participation in the educational conference and end-of life care simulations increased the knowledge of most nurses (P<0.05). CONCLUSION: Conferences and low-fidelity simulation are effective methods for improving nurses' knowledge of end-of-life care in India. Improved education surrounding end of life may positively affect attitudes. PMID- 29172893 TI - Effect of age, sex and body weight on the serum concentrations of cobalamin and folate in cats consuming a consistent diet. AB - Objectives Multiple feline diseases involving the gastrointestinal tract, pancreas, liver and biliary tract are known to cause abnormal serum cobalamin and folate concentrations. Measuring the serum concentration of these vitamins can therefore be a helpful diagnostic tool. However, factors other than disease, in particular age, have also been suggested to have an effect on the serum concentration of cobalamin and folate. In previous studies, the dietary intake was not standardised, or even known, despite diet being the prinicpal source of both vitamins. Therefore, we evaluated the effect of age, sex and body weight on the serum concentration of folate and cobalamin in cats fed the same diet. Methods The serum cobalamin and folate concentrations were measured in 65 apparently healthy cats in a nutrition colony that had been fed an identical diet. A linear model was used to test the relationship between the serum concentration of cobalamin and folate with the variables age, sex and body weight. Results There was a large variation in the serum concentration of both folate and cobalamin, despite identical intake. Serum cobalamin was inversely associated with age ( P = 0.002), and males had higher concentrations than females ( P = 0.039). Serum folate was positively associated with age ( P = 0.01). Conclusions and relevance Independent of diet, serum cobalamin concentration decreases with age. Changes in gastrointestinal function, microflora or metabolism may be responsible. Older cats may be more susceptible to cobalamin deficiency secondary to inappetence or gastrointestinal disease.

PMID- 29172895 TI - Optimal gain control step sizes for bimodal stimulation. AB - OBJECTIVE: Cochlear implants (CI) and hearing aids (HA) have a gain control that allows the bimodal user to change the loudness. Due to differences in dynamic range between CI and HA, an equal change of the gains of the two devices results in different changes in loudness. The objective was to relate and individualise the step sizes of the loudness controls to obtain a similar perceptual effect in the two ears. DESIGN: We used loudness models parametrised for individual users to find a relation between the controls of the CI and the HA such that each step resulted in an equal change in loudness. We conducted loudness balancing experiments to validate the results. STUDY SAMPLE: Eleven bimodal users of whom six were tested in a prior study. RESULTS: The difference between the optimal gain from the loudness balancing procedure and actual gain was 3.3 dB when the new relation was applied. In contrast, the difference was 8 dB if equal step sized were applied at both sides. CONCLUSION: We can relate the controls such that each step results in a similar loudness difference. PMID- 29172896 TI - Tai Chi for Posttraumatic Stress Disorder and Chronic Musculoskeletal Pain: A Pilot Study. AB - PURPOSE: Explore the feasibility of a Tai Chi intervention to improve musculoskeletal pain, emotion, cognition, and physical function in individuals with posttraumatic stress disorder. DESIGN: Two-phase, one-arm quasi-experimental design. METHOD: Phase 1: 11 participants completed one Tai Chi session, feasibility questionnaire, and were offered participation in Phase 2, a 12-week Tai Chi intervention. Ten participants participated in Phase 2. Pain intensity, interference, physical function scales, an emotional battery, and cognition tests were used for pre- and postintervention outcome measures. Paired t tests and thematic analysis were used for analysis. FINDINGS: In Phase 1, most felt Tai Chi would benefit health (90.9%) and expressed interest in continuing Tai Chi (6.73 out of 7). Phase 2 results showed improvement in fear-affect (raw t = -2.64, p = .03; age adjusted t = -2.90, p = .02), fear-somatic arousal (raw t = -2.53, p = .035), List Sorting Working Memory (raw t = 2.62, p = .031; age adjusted t = 2.96, p = .018), 6-Minute Walk Test ( t = 3.541, p = .008), and current level of Pain Intensity ( t = -4.00, p = .004). CONCLUSIONS: Tai Chi is an acceptable, holistic treatment to individuals with musculoskeletal pain and posttraumatic stress disorder. It may reduce pain, improve emotion, memory, and physical function. PMID- 29172897 TI - Tied to the worldly work of writing: Parent as ethnographer. AB - Parent narratives have contributed to ethnographic accounts of the lives of children with autism, but there are fewer examples of parents producing their own autoethnographies. This article explores the affordances of an online blog for enabling a parent of a child with autism to produce a written record of practice which may be considered 'autoethnographic'. Richardson's framework for ethnography as Creative Analytic Process (CAP) is applied to extracts from a blog post in order to consider its contribution, reflexivity, aesthetic merit and impact. The article addresses the methodological and ethical implications of reconceptualizing parents as researchers and the potential contribution of new writing platforms to the development of auto/ethnography. PMID- 29172898 TI - Mitochondrial genome mutations in 13 subunits of respiratory chain complexes in Chinese Han and Mongolian hypertensive individuals. AB - Mitochondrial DNA (mtDNA) mutations are associated with cardiovascular disease, including hypertension (HTN). Here we performed a genetic and molecular analysis of 13 mtDNA-encoded subunits of respiratory chain complexes in 100 Chinese Han and 80 Mongolian HTN cases, and 100 Han and 42 Mongolian normotension subjects. The total cholesterol of the Mongolian normotensive subjects was higher than that of the Han normotensive group (p < .05). Sequence analysis identified 636 point mutations in the 13 mtDNA-encoded subunits in the Han and Mongolian hypertensive individuals, including 66 in NADH dehydrogenase subunit 1(ND1), 62 in ND2, 71 in COI, 29 in COII, 17 in ATP8, one in ATP6/8, 49 in ATP6, 27 in COIII, 27 in ND3, 14 in ND4L, 74 in ND4, 97 in ND5, 24 in ND6, and 78 in CYTB. Eight of these point mutations were present at significantly different frequencies in Han and Mongolian hypertensive individuals. Thirty-one point mutations were present only in Mongolian hypertensive individuals, while 73 were present only in Han hypertensive individuals. The relation between point mutations in 13 mtDNA encoded subunits of respiratory chain complexes and HTN is worth to further research in future; however, the functional effects of these mutations require elucidation. PMID- 29172899 TI - How does feedback from patients impact upon healthcare student clinical skill development and learning? A systematic review. AB - BACKGROUND: A key feature of health professionals' training, irrespective of discipline, is the acquisition and application of clinical and communication skills. Despite this, little is known about the potential role of patient feedback on this process. This systematic review aimed to answer the question: How does feedback from patients impact upon healthcare student clinical skill development and learning? DESIGN: Systematic review of published literature. METHODS: Electronic databases were searched for studies that explored the effects of patient feedback on student learning and were published before March 2016. Eligible articles underwent methodological evaluation using the McMaster University Critical Evaluation Forms and data extraction. RESULTS: A total of 237 articles were retrieved following searches of electronic databases and hand searches of reference lists. Twelve (7 quantitative, 2 qualitative, 3 mixed methods) studies met the inclusion criteria. Eleven studies reported that patient feedback improved students' clinical skills. CONCLUSION: Minimal research has explored the impact of patient feedback on student learning. The research to date suggests that direct feedback from patients may be beneficial for the development of students' communication and clinical skills; however, the wide variety of evaluation methods and the lack of validated tools for patients to provide feedback suggest that further exploration is warranted.

AB - Objectives The aim of this study was to evaluate changes in circulating insulin like growth factor type 1 (IGF-1) concentrations in hyperthyroid cats, before and after thiamazole treatment. Methods Thirty-four hyperthyroid cats were retrospectively included. Plasma free thyroxine (fT4) and IGF-1 concentrations were measured at diagnosis and 3 months after initiating antithyroid drug therapy. Results Median fT4 significantly decreased ( P <0.001) after treatment (from 78 pmol/l [range 43-122 pmol/l] to 31 pmol/l [range below assay limit of detection to 88 pmol/l]), whereas IGF-1 values significantly increased ( P <0.001) after treatment (from 117 ng/ml [33-341 ng/ml] to 221 ng/ml [36-865 ng/ml]). fT4 and IGF-1 concentrations were significantly negatively correlated both at diagnosis (r = -0.43, P = 0.01) and after treatment (r = -0.51, P = 0.002). Conclusions and relevance In cats, IGF-1 concentrations appear to be inversely proportional to the severity of hyperthyroidism and significantly increase after treatment with thiamazole. PMID- 29172900 TI - Development of a high-yield expression and purification system for platelet factor 4. AB - Heparin-induced thrombocytopenia (HIT) is an adverse drug reaction characterized by IgG antibodies bound to complexes of platelet factor 4 (PF4) and heparin. The majority of diagnostic tests for HIT rely on an exogenous source of PF4 to identify anti-PF4/heparin antibodies. These include the PF4-dependent enhanced serotonin release assay (PF4-SRA) among others. Using a bacterial expression system, we developed a novel and efficient method of producing recombinant human PF4 (rhPF4) that is biochemically and antigenically similar to platelet-derived human PF4. rhPF4 was produced using the pET expression system in the BL21(DE3) strain of Escherichia coli. The system was optimized for protein expression using isopropyl beta-D-1-thiogalactopyranoside at different induction temperatures and incubation times. rhPF4 solubility was improved by using different detergents during cell lysis and by purifying with heparin affinity and ion exchange chromatography. Biochemical characteristics of rhPF4 were investigated using mass spectrometry, SDS-PAGE analysis, and gel filtration chromatography and compared to platelet-derived PF4. Antigenic and functional characteristics of rhPF4 were studied using the anti-PF4/heparin EIA and the PF4-SRA. Using this method, we could produce 11.4 +/- 0.6 mg of pure rhPF4 per liter of bacterial culture. Absorbance readings from the anti-PF4/heparin EIA using platelet-derived and rhPF4 were highly correlated (n = 194; r = 0.9545, p < 0.0001); and functional release of serotonin in the PF4-SRA induced by anti-PF4/heparin antibodies was similar to either platelet-derived or rhPF4 and heparin (r = 0.9597, p < 0.0001). Our method of rhPF4 production is efficient and does not rely on a source of platelets. The rhPF4 purification method described produces greater yields at a lower cost than other current methods. The application of this method can improve the efficiency of biochemical investigations and HIT diagnostic testing by supplying sufficient amounts of PF4.

This article presents a repeated measures intervention design study using mixed methods to investigate a self-care simple meditation practice for nurse leaders. Themes and subthemes emerged in association with the three data collection points: at baseline (pretest), after 6 weeks, and after 12 weeks (posttest) from introduction of the self-care simple meditation practice. An analysis of variance yielded a statistically significant drop in perceived stress at 6 weeks and again at 12 weeks. Conducting future research is merited. PMID- 29172904 TI - The Association Between Past Sexual Abuse and Depression in Older Adults From Colombia. AB - To explore the association between past sexual abuse and depression in elders living in Bogota, Colombia, we used data from the SABE (Salud, Bienestar y Envejecimiento [Health, Well-being, and Aging]) Bogota Study. Participants were 2000 community-dwelling adults aged 60 years and older in 2012. Sexual abuse was assessed by self-report. Depression was measured by the Geriatric Depression Scale. The weighted prevalence estimate was 2.6% for past sexual abuse and 23.4% for depression. Multivariate data analyses showed significantly higher odds of depression for past sexual abuse (odds ratio [OR] = 3.91, 95% confidence interval [CI]: 2.13-7.16). Other characteristics associated with depression were history of being displaced by violence (OR = 1.77, 95% CI: 1.30-2.40), low socioeconomic status, low education, poor self-rated health status, and poor self-rated memory. Thus, past sexual abuse and history of being displaced by violence were strongly associated with depression among Colombian elderly individuals.

AB - Objectives The aim of the study was to utilise a large database available from a UK-based, commercial veterinary diagnostic laboratory to ascertain the prevalence of different forms of cutaneous neoplasia within the feline population, and to detect any breed, sex or age predilections for the more common tumours. Methods Records from the laboratory were searched for feline submissions received between 31 May 2006 and 31 October 2013. For masses arising within the skin for which histopathology had been performed, the diagnosis was recorded together with the breed, age, sex and neuter status of the cat. Odds ratios for breed predisposition to skin tumours overall, to histologically malignant tumours and to the more commonly occurring tumours were calculated, with the non-pedigree cat population as the control. Results Of the 219,083 feline samples submitted, masses arising within the skin comprised 4.4% and there were 89 different diagnoses recorded for these masses. Just 6.6% of these cases were non-neoplastic in nature, and, of neoplastic masses, 52.7% were considered histologically malignant. The 10 most common skin tumour types accounted for 80.7% of cases, with the four most common being basal cell tumours, fibrosarcomas, squamous cell carcinomas and mast cell tumours. Conclusions and relevance Despite the large number of different diagnoses in this study, a relatively small number of tumour types accounts for the majority of skin masses occurring in cats, most of which are neoplastic in nature. There are a number of breed predispositions for the more common tumour types, although no pedigree breed had increased odds of developing a malignant tumour compared with the non-pedigree cat population; several breeds had significantly decreased odds. Just over half of the neoplastic masses in this study were considered histologically malignant. PMID- 29172906 TI - Telenursing and Nurse-Patient Communication Within Fertility, Inc. AB - The purpose of this study is to examine patient perceptions of practitioner patient communication in reproductive endocrinology and infertility (REI) practices. During this study, we uncovered the importance of telenursing for nurse-patient communication during REI treatment. Telenursing, which is defined as the use of wireless technology for out-of-office communication, is the basis for out-of-office communication. We examined participants' conceptualization of supportive and unsupportive communication, through the lens of biomedicalization theory. After conducting 23 interviews, we conclude that telenursing is integral to providing holistic nursing care during treatment at REI practices. We discuss efficient and effective uses of telenursing and patients' positive perceptions telenursing and assess telenursing as both an embrace of and form of resistance to biomedicalization within Fertility, Inc. Theoretical and practical implications are offered, including suggestions for increasing patient access to telenursing while protecting REI nurses from burnout.

AB - Integrative Nurse Coaching is a new practice in professional nursing. The purpose of this pilot study is to describe Integrative Nurse Coach Certificate Program graduates' personal and professional experiences. This is a qualitative, pilot study with a convenience sample of Integrative Nurse Coach Certificate Program graduates ( n = 13). Researchers conducted semistructured interviews and identified common themes. The pilot study found four common themes from the participants' experiences as follows: (1) development of self, (2) enriched self care, (3) a call to action for facilitating the health care paradigm shift, and (4) incorporating Integrative Nurse Coaching into practice. The pilot study's findings and conclusions provide insight into the potential benefits of Integrative Nurse Coaching and the importance of nurse self-care. PMID- 29172909 TI - Health Care Utilization Following Vagus Nerve Stimulation Therapy in Pediatric Epilepsy Patients From a Pediatric Accountable Care Organization. AB - BACKGROUND: Vagus nerve stimulation has been a therapy for epilepsy approved by the US Food and Drug Administration (FDA) for patients 4 and older and shown efficacy and safety in younger pediatric patients. METHODS: The authors performed a retrospective analysis utilizing Medicaid claims from an accountable care organization to measure the intervention of vagus nerve stimulation therapy in regard to unplanned health care utilization. Thirteen unique patients were included who had vagus nerve stimulation therapy who had at least 6 months of continuous enrollment in a managed Medicaid health plan. Comparison with 12 months of data before and after vagus nerve stimulation implantation was performed. RESULTS: Patients had statistically significant fewer unplanned inpatient visits per patient per enrollment month after vagus nerve stimulation implantation. CONCLUSION: Utilizing claims data, vagus nerve stimulation implantation demonstrates a reduction in unplanned hospitalizations. PMID- 29172910 TI - Comparison of real-time PCR with fungal culture for the diagnosis of Microsporum canis dermatophytosis in shelter cats: a field study. AB - Objectives Fungal culture requires at least 14 days for a final result, compared with 1-3 days for PCR. The study compared a commercial real-time dermatophyte PCR panel with fungal culture in cats in a shelter setting for: (1) diagnosis of Microsporum canis infection; and (2) determination of mycological cure. Methods This was a cross-sectional, observational study of cats with suspicious skin lesions or suspected exposure to dermatophytosis. Hair samples were collected for fungal culture and PCR prior to treatment and at weekly intervals until two negative culture results were obtained. Results One hundred and thirty-two cats were included, of which 28 (21.2%) were culture positive and 104 (78.8%) culture negative for M canis. PCR correctly identified all culture-positive cats and 92/104 culture negative cats; there were 12 false-positive PCR results. The sensitivity and specificity of PCR were 100% (95% confidence interval [CI] 87.7 100) and 88.5% (95% CI 80.7-93.9), respectively. Data from 17 cats were available for assessment of mycological cure. At the time of the first and second negative fungal cultures, 14/17 (82.4%) and 11/17 (64.7%) tested PCR positive, respectively. Conclusions and relevance PCR showed high sensitivity and specificity for diagnosis of M canis dermatophytosis compared with fungal culture, but was unreliable for identifying mycological cure. False-positive results were relatively common. There were no false-negative PCR results and a negative PCR test was a reliable finding in this study. The ability to rapidly diagnose or rule out dermatophytosis could be a valuable tool to increase life saving capacity in animal shelters.

AB - PURPOSE: Describe community nurses' experiences regarding the meaning and promotion of healthy aging in northeastern Thailand. METHOD: Data were collected through five focus group interviews with 36 community nurses in northeastern Thailand. Latent content analysis was conducted to analyze the data. FINDINGS: Healthy aging was characterized by the interconnection of older persons, older persons' family members, and the community. Healthy aging was associated with two themes: "being strong" and "being a supporter and feeling supported." The nurses' experiences in promoting healthy aging were described by the themes "providing health assessment," "sharing knowledge," and "having limited resources." CONCLUSIONS: The findings of this study provide a deeper understanding of the meaning of healthy aging from a holistic viewpoint. Community nurses must pay attention to older persons and their surroundings when planning how to promote healthy aging. Person-centeredness should be applied in practice to promote healthy aging. The current findings contribute useful information that should help policy makers develop healthy aging strategies in Thailand. PMID- 29172915 TI - Sedentary Behavior, Psychosocial Stress Indicators, and Health-Risk Behaviors Among Adolescents in Northeastern Brazil. AB - OBJECTIVES: To analyze psychosocial stress indicators and health-risk behaviors associated with sedentary behavior. METHODS: This is a cross-sectional school based study with a representative sample of high school students enrolled in public state schools of Sergipe, Brazil, with the sample composed of 3992 adolescents aged 14-19 years. Data were collected through self-administered questionnaire. The time spent in activities, such as watching television, playing computer games, chatting with friends, and playing cards or dominoes, was used as a measure of sedentary behavior (>2 h/d = exposed). Level of physical activity, smoking, stress perception, feelings of loneliness, trouble sleeping, and consumption of fruits and vegetables, soft drinks, alcohol, and drugs were analyzed. Binary logistic regression analysis was used for association among variables. RESULTS: The prevalence of sedentary behavior was 46.7% and was associated with low levels of physical activity, consumption of soft drinks, negative stress perception, feelings of loneliness, and trouble sleeping. CONCLUSION: This study showed high proportion of adolescents with sedentary behavior, especially among those who are insufficiently active and exposed to psychosocial stress indicators.

AB - Objectives The objective was to evaluate a nadir-led protocol for transitioning porcine lente insulin suspension (PLIS)-treated diabetic cats onto human recombinant protamine zinc insulin (PZIR). Methods Recently diagnosed (<5 months) diabetic cats, treated with PLIS q12h for ?6 weeks, were recruited. Fructosamine, 24 h blood glucose curve (BGC), quality of life assessment (DIAQoL-pet score) and Diabetic Clinical Score (DCS) were assessed at enrolment (PLIS-treated) and 2, 4 and 12 weeks after transitioning to PZIR (starting dose 0.2-0.7 U/kg q12h). Short duration of insulin action was defined as <9 h. Linear mixed effects modelling assessed for change in fructosamine, mean blood glucose (MBG) during BGCs, DIAQoL pet score, DCS and q12h insulin dose. McNemar's tests compared the proportion of cats with hypoglycaemia at week 0 (PLIS-treated) and week 4 (PZIR-treated). Results Twenty-two cats were recruited. Median PLIS dose at enrolment was 0.5 U/kg (interquartile range 0.3-0.7 U/kg) q12h, equalling median PZIR starting dose (0.5 U/kg; interquartile range 0.3-0.7 U/kg q12h). Transitioning was followed by significant decreases in fructosamine ( P = 0.00007), insulin dose ( P = 0.02), DCS ( P = 8.1 * 10-8) and DIAQoL-pet score ( P = 0.003), indicating improved quality of life. MBG did not alter significantly ( P = 0.1). Five cats (22.7%) achieved remission. Hypoglycaemia was recorded in 30/190 12 h BGCs (15.8%) and five cats experienced clinical hypoglycaemia. The proportion of cats with hypoglycaemia did not differ between PLIS (week 0) and PZIR (week 4) ( P = 1.0). Duration of action was analysed in 19 cats. Six cats (31.6%) showed short duration of action on PLIS, compared with two cats (10.5%) after 4 weeks on PZIR. All six cats with short PLIS duration showed duration of ?9 h on PZIR. Conclusions and relevance Used alongside a low-carbohydrate diet, transitioning to PZIR was associated with significantly improved clinical signs and quality of life, with some cats achieving remission. Transition to PZIR should be considered for cats with short duration of action on PLIS. PMID- 29172918 TI - Diagnostic performances of manual and automated reticulocyte parameters in anaemic cats. AB - Objectives The objective of this study was to evaluate the diagnostic performances of manual and instrumental measurement of reticulocyte percentage (Ret%), reticulocyte number (Ret#) and reticulocyte production index (RPI) to differentiate regenerative anaemia (RA) from non-regenerative anaemia (NRA) in cats. Methods Data from 106 blood samples from anaemic cats with manual counts (n = 74; 68 NRA, six RA) or instrumental counts of reticulocytes (n = 32; 25 NRA, seven RA) collected between 1995 and 2013 were retrospectively analysed. Sensitivity, specificity and positive likelihood ratio (LR+) were calculated using either cut-offs reported in the literature or cut-offs determined from receiver operating characteristic (ROC) curves. Results All the reticulocyte parameters were significantly higher in cats with RA than in cats with NRA. All the ROC curves were significantly different ( P <0.001) from the line of no discrimination, without significant differences between the three parameters. Using the cut-offs published in literature, the Ret% (cut-off: 0.5%) was sensitive (100%) but not specific (<75%), the RPI (cut-off: 1.0) was specific (>92%) but not sensitive (<15%), and the Ret# (cut-off: 50 * 103/ul) had a sensitivity and specificity >80% and the highest LR+ (manual count: 14; instrumental count: 6). For all the parameters, sensitivity and specificity approached 100% using the cut-offs determined by the ROC curves. These cut-offs were higher than those reported in the literature for Ret% (manual: 1.70%; instrumental: 3.06%), lower for RPI (manual: 0.39; instrumental: 0.59) and variably different, depending on the method (manual: 41 * 103/ul; instrumental: 57 * 103/ul), for Ret#. Using these cut-offs, the RPI had the highest LR+ (manual: 22.7; instrumental: 12.5). Conclusions and relevance This study indicated that all the reticulocyte parameters may confirm regeneration when the pretest probability is high, while when this probability is moderate, RA should be identified using the RPI providing that cut-offs <1.0 are used. PMID- 29172919 TI - The drill wobble effect: oversizing the femoral tunnel during ACL reconstruction. AB - OBJECTIVES: In ACL reconstruction, autologous tendon graft can be attached to the femur, within a boney tunnel, using an Endobutton device. The ultimate aim being to achieve biological fixation and incorporation into the bone. Accurate bone tunnel diameter to match the tendon graft is vital to biologic incorporation and strength. The common technique of in sequence passing a guide wire, a cannulated 4.5 mm Endobutton drill, then a cannulated femoral socket drill causes the guidewire to lose cortical fixation and stability before the femoral socket drill is passed. The Objective of this study is to analyze this common technique of femoral socket creation and determine if it results in unintentionally oversizing the femoral socket due to femoral socket drill-wobble over a destabilised guide wire. METHODS: 12 cadaveric femoral pairs equally divided between two groups underwent femoral socket creation in one of the two following sequences. Group 1: Guidewire, 4.5 mm endobutton drill, 8 mm femoral socket drill. Group 2: Guidewire, 8 mm femoral socket drill, 4.5 mm endobutton drill. The created femoral tunnels apertures and calibres were measured and then compared for accuracy between the two groups. RESULTS: Passing the 4.5 mm drill before the 8 mm socket drill results in oversized tunnel apertures and calibres when compared to passing an 8 mm socket drill after the 4.5 mm drill has been passed (p<0.0001). CONCLUSION: To most precisely create an 8 mm femoral socket in ACL reconstruction, the 8 mm femoral socket reamer followed by the 4.5 mm should be passed over the guide wire to prevent guide wire destabilization and drill wobble. PMID- 29172920 TI - Clinicopathologic Features of Benign Neurogenic Tumor of Urinary Bladder. AB - BACKGROUND: Benign neurogenic tumor involving the urinary bladder is a very rare and heterogeneous disease group. The clinical and radiological diagnosis may be difficult because of the disease's rarity and the histological similarities of each disease especially in needle biopsy specimens. However, accurate diagnosis is very important because the clinical course of each disease, even within the same diseases, is quite variable. In this study, we investigated 7 benign neurogenic tumors to better understand the rare disease entity in the urinary bladder by analyzing histological and immunohistochemical findings and comparing clinicopathologic features. METHODS: We collected the cases by searching the medical records database of Seoul National University Hospital from 2000 to 2016. RESULTS: We identified 3 ganglioneuromas, 2 schwannomas, 1 neurofibroma, and 1 granular cell tumor involving the urinary bladder. There were some limitations for the initial clinical and radiological diagnosis and even pathologic diagnosis using needle biopsy specimens. One infant patient was diagnosed radiologically with rhabdomyosarcoma, but the final diagnosis changed to ganglioneuromatosis. The initial needle biopsy diagnosis of 2 ganglioneuroma cases showed neurofibroma. All patients underwent a local resection, and 1 granular cell tumor patient suffered with pain because of a recurrent tumor. One neurofibromatosis patient had a lesion appear 34 months after the bladder operation, so he underwent repeated debulking operations, but he was diagnosed with malignant transformation after 8 years. CONCLUSIONS: An understanding of benign neurogenic tumors involving the urinary bladder and the sharing of rare experiences surrounding them are required to provide accurate diagnoses. PMID- 29172921 TI - Immunity and inflammation predictors for short-term outcome of stroke in young adults. AB - BACKGROUND: The current study was conducted to identify independent predictors of severity and short-term outcome of first-ever ischemic stroke in young adults. METHODS: We retrospectively enrolled 325 consecutive patients aged 18-49 years with first-ever ischemic stroke admitted to our center between April 2013 and June 2015. Variables were systematically registered and compared between patients with different neurological severity (mild stroke: National Institutes of Health Stroke Scale [NIHSS] <= 8 and severe stroke: >8) and different stroke outcome (favorable: modified Rankin scale score 0-2 and unfavorable: 3-5 or death) at 14 days after stroke onset. RESULTS: A total of 325 patients fulfilled the inclusion criteria. There were 242 patients with mild stroke. They exhibited lower white blood cell (WBC), globulin, plasma glucose, fibrinogen (Fib) levels and higher albumin, albumin/globulin (A/G), free triiodothyronine (FT3) levels. Logistic regression analysis showed that FT3 (?3.18) and WBC (?7.1) were independent predictors. There were 122 patients demonstrating an unfavorable outcome. Higher WBC, globulin, plasma glucose and Fib levels, lower albumin, FT3, A/G levels, higher NIHSS score and longer hospital stay were significantly associated with unfavorable outcome. In the logistic regression model, we found that A/G (?1.56), FT3 (?4.09) and WBC (?7.1) were independent predictors for short-term outcome. CONCLUSIONS: Our data suggested that higher A/G, FT3 levels served as independent predictors of favorable outcome, and a higher FT3 value may also predict mild stroke, while higher WBC may predict a poor functional outcome and severe stroke in patients with acute ischemia. PMID- 29172922 TI - Thiol/disulfide homeostasis in pregnant women with obstructive sleep apnea syndrome. AB - BACKGROUND: Repetitive episodes of hypoxia and reoxygenation during sleep in patients with obstructive sleep apnea syndrome (OSAS) resemble an ischemia reperfusion injury. We aimed to test the hypothesis that oxidative stress occurs in pregnant women with OSAS. We also aimed to compare thiol/disulfide homeostasis with ischemia-modified albumin (IMA) and total antioxidant capacity (TAC) as markers of ischemia-reperfusion injury in pregnant women with and without OSAS and healthy control. METHODS: This study included 29 pregnant women with OSAS, 30 women without OSAS in the third trimester applying for periodic examinations, and 30 healthy women. Serum IMA and TAC (using the ferric reducing power of plasma method) were measured. Serum thiol/disulfide homeostasis was determined by a novel automated method. RESULTS: The mean age of the pregnant women with OSAS was 31.0 +/- 4.7 years with a mean gestational age of 36.5 +/- 3.0 weeks. The mean age of pregnant women without OSAS was 29.8 +/- 4.9 years with a mean gestational age of 36.9 +/- 2.7 weeks. The mean age of the nonpregnant control group was 29.7 +/- 6.4 years. Both native thiol (291 +/- 29 MUmol/L versus 314 +/- 30 MUmol/L; p = .018) and total thiol (325 +/- 32 versus 350 +/- 32, p = .025) levels were lower in pregnant women with OSAS compared to pregnant women without OSAS, respectively (p < .01). CONCLUSIONS: This is the first study demonstrating the thiol/disulfide homeostasis in pregnant women with OSAS. Native thiol and total thiol levels were lower in pregnant women with OSAS compared to those without OSAS. However, dynamic thiol/disulfide homeostasis parameters cannot provide valuable information to discriminate OSAS in pregnant women. PMID- 29172923 TI - Psychosocial Outcomes 12 Months Following a Dose-Response Aerobic Exercise Intervention in Postmenopausal Women. AB - BACKGROUND: We previously reported no postintervention differences in quality of life and other psychosocial outcomes when comparing 12-month high versus moderate volume of aerobic exercise in postmenopausal women. Here, we report the 24-month follow-up for these outcomes. METHODS: At 24-month follow-up, 333 out of 400 postmenopausal women were randomized to a year-long intervention of 150 (moderate) or 300 (high) minutes per week of aerobic exercise returned a battery of self-reported measures assessing quality of life, psychosocial outcomes, and sleep quality, also assessed at baseline and postintervention. Intention-to-treat analyses using linear models were conducted to determine the changes between baseline and 24-month follow-up. RESULTS: No significant effects between moderate and high-volume aerobic exercise groups were observed among any outcomes. There was some evidence of effect moderation by baseline body mass index in relation to quality of life, psychosocial outcomes, and sleep quality, where obese women benefitted from the moderate-volume exercise and nonobese women benefitted from the high-volume exercise prescription. CONCLUSION: Although high-volume aerobic exercise did not improve psychosocial outcomes when compared with moderate volume at the 24-month follow-up, we did observe potential effect of moderation between obese and nonobese women. Confirmation of these interactions is warranted in this population. PMID- 29172925 TI - Parents' Experiences and Responses to an Intervention for Psychological Preparation of Children and Families During the Child's Radiotherapy. AB - The aim of this study was to evaluate parents' experiences and responses to a systematic intervention for psychological preparation of children and families during the child's radiotherapy (RT) treatment. In this case-control study at 3 pediatric RT centers, an intervention with a preparatory kit, including age adjusted information on tablets, gift of a stuffed toy or a pair of headphones, a parent booklet, and toy models of the computed tomography and RT machines was implemented. For evaluation, a mixed methods data collection was conducted. A total of 113 parents of children undergoing RT were included-n = 59 in the baseline group and n = 54 in the intervention group. Health-related quality of life was rated low, but parents in the intervention group expressed less anxiety after the RT compared with the baseline group. They found information suitable for their young children, siblings, and friends were involved and the toy models were used for play. Parents expressed positive feelings due to close interaction with staff and each other within the family. The solutions developed within a human-centered design approach and shaped as a systematic family-centered strategy contributed to parents understanding and coping with the child's RT. PMID- 29172924 TI - PINK1-PRKN/PARK2 pathway of mitophagy is activated to protect against renal ischemia-reperfusion injury. AB - Damaged or dysfunctional mitochondria are toxic to the cell by producing reactive oxygen species and releasing cell death factors. Therefore, timely removal of these organelles is critical to cellular homeostasis and viability. Mitophagy is the mechanism of selective degradation of mitochondria via autophagy. The significance of mitophagy in kidney diseases, including ischemic acute kidney injury (AKI), has yet to be established, and the involved pathway of mitophagy remains poorly understood. Here, we show that mitophagy is induced in renal proximal tubular cells in both in vitro and in vivo models of ischemic AKI. Mitophagy under these conditions is abrogated by Pink1 and Park2 deficiency, supporting a critical role of the PINK1-PARK2 pathway in tubular cell mitophagy. Moreover, ischemic AKI is aggravated in pink1 andpark2 single- as well as double knockout mice. Mechanistically, Pink1 and Park2 deficiency enhances mitochondrial damage, reactive oxygen species production, and inflammatory response. Taken together, these results indicate that PINK1-PARK2-mediated mitophagy plays an important role in mitochondrial quality control, tubular cell survival, and renal function during AKI. PMID- 29172927 TI - Measuring Eating Compulsivity in the Wider Clinical Context. PMID- 29172926 TI - Sumoylation Contributes to Timekeeping and Temperature Compensation of the Plant Circadian Clock. AB - The transcriptional circadian clock network is tuned into a 24-h oscillator by numerous posttranslational modifications on the proteins encoded by clock genes, differentially influencing their subcellular localization or activity. Clock proteins in any circadian organism are subject to posttranslational regulation, and many of the key enzymes, notably kinases and phosphatases, are functionally conserved between the clocks of mammals, fungi, and plants. We now establish sumoylation, the posttranslational modification of target proteins by the covalent attachment of the small ubiquitin-like modifier protein SUMO, as a novel mechanism regulating key clock properties in the model plant Arabidopsis. Using 2 different approaches, we show that mutant plant lines with decreased or increased levels of global sumoylation exhibit shortened or lengthened circadian period, respectively. One known functional role of sumoylation is to protect the proteome from temperature stress. The circadian clock is characterized by temperature compensation, meaning that proper timekeeping is ensured over the full range of physiologically relevant temperatures. Interestingly, we observed that the period defects in sumoylation mutant plants are strongly differential across temperature. Increased global sumoylation leads to undercompensation of the clock against temperature and decreased sumoylation to overcompensation, implying that sumoylation buffers the plant clock system against differential ambient temperature.

PMID- 29172929 TI - Telehealth for the management of blood pressure in patients with chronic kidney disease: A systematic Review. AB - Background Most patients with chronic kidney disease (CKD) fail to achieve blood pressure (BP) management as recommended. Meanwhile, the effects of promising intervention and telehealth on BP control in CKD patients remain unclear. We aimed to evaluate the efficacy of telehealth for BP in CKD non-dialysis patients. Methods Databases including MEDLINE, EMBASE, CENTRAL, CNKI, Wanfang, VIP and CBM were systematically searched for randomised controlled trials or quasi-randomised controlled trials on telehealth for BP control of CKD3-5 non-dialysis patients. We analysed systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), serum creatinine, and estimated glomerular filtration rate (eGFR) with a fixed-effects model. Results Three studies, with total 680 subjects, were included in our systematic review and two were included for meta analysis. Pooled estimates showed decreased SBP (pooled mean difference (MD), 5.10; 95% confidence interval (CI), -11.34, 1.14; p > 0.05, p = 0.11), increased DBP (pooled MD, 0.45; 95% CI, -4.24, 5.13; p > 0.05, p = 0.85), decreased serum creatinine (pooled MD, -0.38; 95% CI, -0.83, 0.07; p > 0.05, p = 0.10) and maintained eGFR (pooled MD, 4.72; 95% CI, -1.85, 11.29; p > 0.05, p = 0.16) in the telehealth group. There was no significant difference from the control group. MAP (MD, 0.6; 95% CI, -6.61, 7.81; p > 0.05, p = 0.87) and BP control rate ( p > 0.05, p = 0.8), respectively, shown in two studies also demonstrated no statistical significance in the telehealth group. Conclusions There was no statistically significant evidence to support the superiority of telehealth for BP management in CKD patients. This suggests further studies with improved study design and optimised intervention are needed in the future. PMID- 29172930 TI - Health Warnings, Smoking Rules, and Smoking Status: A Cross-National Comparison of Turkey and the United States. AB - OBJECTIVES: This study aimed to compare the prevalence of smoking status (i.e., current, former and never) between the United States and Turkey in terms of age and gender, and examine how smoking rules and health warnings are associated with smoking status within and between the two countries. METHODS: The study used data from the 2012-2013 National Adult Tobacco Survey (U.S. sample, N = 60,196) and the 2012 Global Adult Tobacco Survey (Turkey sample, N = 9,581). SAS PROC SURVEYLOGISTIC with a weighted variable was used to examine the associations between demographics (age, gender and education), smoking rules, health warnings, and smoking status within and between the two countries. RESULTS: There was an 18% current smoking prevalence among U.S. sample, compared to 27% of the Turkey sample. The U.S. sample had a higher rate of former smoking compared to the Turkey sample (25% vs. 22%). In both countries, being older and male gender predicted former smoking while being younger and female gender predicted never smoking. Having seen a health warning, and not allowing smoking in the vehicle and home positively predicted former and never smoking status. Higher education predicted both smoking statuses in the U.S. only. CONCLUSIONS: It is important to work with partners particularly in low- and middle-income countries (e.g., Turkey) to combat the global tobacco epidemic. In both counties, cessation endeavors should emphasize a comprehensive understanding of smoking status in terms of smoking rules in personal spaces and health warnings. PMID- 29172931 TI - HIF2A germline-mutation-induced polycythemia in a patient with VHL-associated renal-cell carcinoma. AB - In this study, we report here a rare case of polycythemia and cRCC in the same patient, which may be helpful in understanding clinical features and molecular mechanisms underlying VHL-mutation-associated cRCC and polycythemia induced by germline mutation of HIF2A. Firstly, we identified a rare but well studied germline mutation resulting in polycythemia in HIF2A (c.1609G>A, p.Gly537Arg) in the blood of the patient and his daughter. Meanwhile, we identified an inactivating VHL mutation (c.391A>T, p.N131Y), as well as TP53 mutation(c.977A>T, p.E326V) and mTOR mutation(c.7498A>T, p.I2500F) in renal cancer tissue. Moreover, protein levels of VHL, HIF1A, HIF2A, EPO, and VEGF estimated by immunohistochemical staining substantiated hyperactivation of the oxygen-sensing pathway. In addition, we identified 158 somatic SNP/indel mutations, including 90 missense/nonsense/splice/stop-loss mutations by whole-exome sequencing (WES) of the tumor specimen and matched normal DNA. PMID- 29172932 TI - Treatment Seeking among College Students with Comorbid Hazardous Drinking and Elevated Mood/Anxiety Symptoms. AB - BACKGROUND: Hazardous drinking is prevalent among college students and often comorbid with mood and/or anxiety disorders; however, these disorders frequently go untreated. Prior studies have found that individuals with comorbid hazardous drinking are more likely to seek treatment than those with an hazardous drinking alone. OBJECTIVES: The current study tested possible psychological and structural explanations to understand these treatment seeking behaviors. METHODS: A sample of 222 students identified as hazardous drinkers (AUDIT >= 8) participated from September 2010 to April 2011. Behavioral measures designed to mimic actual treatment seeking and self-report measures were used to assess treatment seeking behaviors, and the influence of psychopathology and individual predictors on treatment interest. RESULTS: Students were more interested in treatment for emotional problems than for alcohol problems. Further, treatment seeking interest was significantly higher among individuals with comorbid hazardous drinking. When provided a telephone offer for a free on-campus clinic appointment, no students were interested in receiving treatment for alcohol use problems, but some were interested in an appointment for emotional problems (n = 13). Of those students expressing interest on the phone, seven attended the clinic appointment. Logistic regression analyses revealed that students with anxiety, anxiety sensitivity, and depression were more likely to attend the clinic appointment. Conclusions/Importance: In sum, targeting mood and anxiety disorders may be a viable way to increase treatment seeking rates in hazardous drinking college students.

AB - PURPOSE: Work-related stress among midwives results in secondary traumatic stress, posttraumatic stress disorder, and job attrition. The purpose of this pilot project was to evaluate the effectiveness of a holistic, web-based program using holistic modalities for stress reduction and improved coping among certified nurse-midwives. DESIGN AND METHOD: A convenience sample of 10 midwives participated in a web-based holistic stress reduction intervention using yoga, mindfulness-based stress reduction, and meditation for four days each week over 4 weeks. Participants completed pre- and postintervention questionnaires (Perceived Stress Scale [PSS] and the Coping Self-Efficacy Scale [CSES]) for evaluation of effectiveness. FINDINGS: The PSS means showed improvement in midwives' stress (16.4-12.3). The CSES means showed improvement in coping (174.8-214.5). Improvement was shown in each subscale of the CSES ("uses problem-focused coping": 19.2%; "stops unpleasant thoughts and emotions": 20.3%; and "gets support from family and friends": 16.6%). CONCLUSION: Findings suggest the potential for stress reduction and improved coping skills after using holistic techniques in a web-based format within a cohort of nurse-midwives. Further research of web-based, holistic intervention for stress reduction among midwives is warranted. PMID- 29172935 TI - Association between ultrasonographic appearance of splenic parenchyma and cytology in cats. AB - Objectives The purpose of this study was to determine whether the presence of a splenic mass or a diffusely moth-eaten parenchyma on ultrasonographic scans could represent potential criteria of malignancy in the feline spleen. Methods Feline patients with ultrasonographic images and cytological analysis of the spleen obtained by fine-needle aspiration were retrospectively included in a multicentre study. Results One hundred and ninety-five cats met our inclusion criteria. There was a lack of agreement between the moth-eaten ultrasonographic appearance of the spleen and the presence of a malignant neoplasia on cytological analysis. The sensitivity and specificity of a moth-eaten parenchyma for predicting malignant neoplastic disease were 13.2% and 84.8%, respectively. The sensitivity and specificity of a splenic mass >1 cm for predicting malignant neoplastic disease were 21.0% and 94.7%, respectively. A marbled appearance of the splenic parenchyma was significantly more frequent among patients examined with a high frequency transducer (11-18 MHz) than among those examined with a low-frequency transducer (6.6-10 MHz) (27.6% vs 11.1%, respectively; P = 0.004). Similarly, although not statistically significant, a moth-eaten parenchyma was more frequent in the high-frequency transducer group than in the low-frequency group (17.1% vs 8.9%, respectively; P = 0.09). Conclusions and relevance Based on our findings, a moth-eaten ultrasonographic appearance of the spleen in cats does not necessarily reflect a lymphoma or another malignant neoplastic process on cytological analysis. The presence of a splenic mass >1 cm on ultrasound is suggestive of malignancy in cats. Finally, the transducer frequency must be taken into account when assessing the splenic parenchyma, as a high-frequency transducer seems to improve the detection of a marbled or moth-eaten parenchyma. PMID- 29172934 TI - Early osteoarthritis after slipped capital femoral epiphysis. AB - Background and purpose - Slipped capital femoral epiphysis (SCFE) results in a more or less pronounced deformity of the proximal femur, sometimes causing impingement and early osteoarthritis. We studied early osteoarthritis after SCFE and the association with deformity and self-reported hip function, pain, and quality of life. Patients and methods - 9 women and 16 men, mean age 32 (21-50) years, 19 with unilateral and 6 with bilateral SCFE, participated. All patients had primarily been operated by pin or screw with no attempt at reposition of the slip. Hips were examined by delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC), which quantifies and locates cartilage degeneration. Plain radiographs were used to measure deformity as determined by the alpha angle. Outcome was assessed by Oxford hip score, Hip Groin Outcome score and EQ-5D-Visual scale. Results - In the 19 unilateral SCFE, on the slip side dGEMRIC mean value was 533 ms (SD 112, range 357-649) versus mean 589 ms (SD 125, range 320-788) on the non-slip side, (p = 0.01). The dGEMRIC correlated negatively to the alpha angle, correlation coefficient (CC) = -0.60, (p = 0.002). Oxford hip score, pain, and EQ-5D-Visual scale correlated to dGEMRIC CC =0.43 (p = 0.03), CC =0.40 (p = 0.05), and CC =0.49 (p = 0.01) respectively. Interpretation - After SCFE, even relatively mild residual hip deformity can be associated with cartilage degeneration. A high alpha angle was associated with worse cartilage status. The Oxford hip score identified symptoms even though our patients had not previously sought medical care after the index operation. Quality of life showed strong inverse correlation with cartilage degeneration. Objective assessment of early cartilage degeneration may be useful for treatment decisions and follow-up. PMID- 29172936 TI - Previously undescribed vitamin D C-3 epimer occurs in substantial amounts in the blood of cats. AB - Objectives The aim of this report is to describe the identification of a novel vitamin D metabolite, a C-3, alpha-epimer of 25-hydroxycholecalciferol (3-epi 25(OH)D3), in serum and plasma extracts of cat blood and compare its abundance in cat, dog and rat serum to 25-hydroxycholecalciferol (25(OH)D3), a conventional marker of vitamin D status. Methods Serum 25(OH)D3 and 3-epi-25(OH)D3 concentrations were measured in healthy cohorts of cats (n = 8), dogs (n = 8) and rats (n = 17) using validated reverse and normal-phase high-performance liquid chromatography methods. The methods were verified using liquid chromatography tandem mass spectrophotometry. Dietary intake and dietary concentrations of vitamin D were also measured for evaluation of species differences and effect of dietary change on vitamin D metabolite concentrations. Differences between cat serum and plasma metabolite concentrations were determined. Results Detectable concentrations of 3-epi-25(OH)D3 were observed in all cats and rats. No 3-epi 25(OH)D3 was detected in dogs, where our limit of detection was 5 ng/ml. There were significant differences ( P <0.05) in serum concentrations of 25(OH)D3 and 3 epi-25(OH)D3 among species, with cats having the greatest concentrations of both metabolites. Serum and plasma results were not significantly different. A diet change, which resulted in an increase in vitamin D intake among the cats, affected serum concentration with an increase ( P = 0.004) in 3-epi-25(OH)D3 but no significant change in 25(OH)D3. Conclusions and relevance Serum and plasma of cats contain 3-epi-25(OH)D3 in varied and extraordinary concentrations, much greater than in rats and certainly than that of dogs, a species for which the metabolite was not detected. Importantly, this finding indicates a C-3 epimerization pathway is quantitatively significant for vitamin D metabolism in domestic cats, making 3-epi-25(OH)D3 assays essential for the evaluation of vitamin D status in cats and positioning the cat as a novel model for study of this pathway.

AB - Panretinal photocoagulation (PRP) is a mainstay of therapy for retinal ischemic disease. The procedure involves creating thermal burns in the peripheral retina leading to tissue coagulation, the overall consequence of which is improved retinal oxygenation. While highly effective, there have been concerns historically regarding the anatomic effects and visual complications following PRP, the most common of which include choroidal effusions, exudative retinal detachments, macular edema, visual field deficits, and night vision defects. The occurrence of these complications is closely tied to laser parameters such as increased duration and power and intensive treatment in a single sitting, all of which cause increased dispersion of thermal energy within the retina and choroid. The advent of newer laser delivery systems, such as the multispot pattern laser, has greatly mitigated but not eliminated these issues. The following article reviews the most common complications following PRP treatment, including reported occurrences, inciting factors, and underlying pathophysiology. PMID- 29172940 TI - Creating a test blueprint for a progress testing program: A paired-comparisons approach. AB - CONTEXT: Creating a new testing program requires the development of a test blueprint that will determine how the items on each test form are distributed across possible content areas and practice domains. To achieve validity, categories of a blueprint are typically based on the judgments of content experts. How experts judgments are elicited and combined is important to the quality of resulting test blueprints. METHODS: Content experts in dentistry participated in a day-long faculty-wide workshop to discuss, refine, and confirm the categories and their relative weights. After reaching agreement on categories and their definitions, experts judged the relative importance between category pairs, registering their judgments anonymously using iClicker, an audience response system. Judgments were combined in two ways: a simple calculation that could be performed during the workshop and a multidimensional scaling of the judgments performed later. RESULTS: Content experts were able to produce a set of relative weights using this approach. The multidimensional scaling yielded a three-dimensional model with the potential to provide deeper insights into the basis of the experts' judgments. CONCLUSION: The approach developed and demonstrated in this study can be applied across academic disciplines to elicit and combine content experts judgments for the development of test blueprints. PMID- 29172939 TI - Rice ERECT LEAF 1 acts in an alternative brassinosteroid signaling pathway independent of the receptor kinase OsBRI1. AB - ERECT LEAF 1 (ELF1) was previously identified as a component of brassinosteroid signaling in rice. A double mutant obtained by crossing elf1-1 (a null mutant of ELF1) with d61-1 (a leaky mutant of OsBRI1) showed a more severe phenotype than did the elf1-1 single mutant, resembling that of a severe brassinosteroid deficient mutant. Microarray analysis showed that the gene expression profile of elf1-1 was distinct from that of d61-12 (a leaky mutant of OsBRI1 with a phenotype similar to that of elf1-1), and fewer than half of genes differentially expressed between the wild-type and elf1-1 showed similar differences in d61-12 relative to the wild-type. These results indicate that less than half of ELF1 regulated genes in rice seedlings are affected by OsBRI1, and suggest that ELF1 acts in a rice brassinosteroid signaling pathway different from that initiated by OsBRI1. Gene expression analysis showed that some stress response-related genes were induced in elf1-1 but not in d61-12, and 8 of 9 genes oppositely regulated in elf1-1 and d61-12 were significantly up- or down-regulated in both elf1-1 and jasmonic acid-treated wild-type. These results imply that ELF1 suppresses stress induced signalling, and that jasmonic acid signaling is stimulated in elf1-1; therefore, ELF1 may be involved in the brassinosteroid-mediated suppression of jasmonic acid response in rice. PMID- 29172941 TI - Reporting of adverse events following immunizations in Ghana - Using disproportionality analysis reporting ratios. AB - BACKGROUND: Timely reporting of safety information post vaccination is pivotal for the success of any vaccination program. Reports of adverse events following immunization (AEFI) of 6 different vaccinations from Ghana were analysed for signals. METHODS: De-identified data from active surveillance for AEFIs after 2009 AH1N1 influenza, yellow fever, meningitis, measles-rubella, pneumococcal rotavirus and human papilloma virus vaccinations were used. All vaccinations occurred between January 2010 and December 2013. The ten most occurring events for each vaccination were captured and arranged using Medical Dictionary for Regulatory Authorities (MedDRA) Preferred Term (PT) and System Organ Classification (SOC) codes. Adverse event incidence rates were calculated for each vaccine type, and signals were generated using proportional reporting ratios (PRR). RESULTS: A total number of 5,141 reports were analysed ranging from 33 (human papilloma virus) to 1958 (measles-rubella). Between 22% and 55% of all AEFIs per vaccine type were collected on the day of vaccination. For each vaccine type, at least 87% of all reported AEFIs occurred in the first 7 days post vaccination. Multiple reports were received per vaccine type. For the MR vaccine, urticarial recorded the highest attack rate of 6.6 (95% CI 6.2, 7.1) per 100,000 vaccines. The AEFI with the highest PRR for both human papilloma and measles rubella vaccines was abdominal pain, recording a PRR of 8.15 (95% CI 3.46, 19.23) and 43.75 (95% CI 17.81, 107.45) respectively. CONCLUSION: These results underscore the competency of public health systems in sub-Saharan African countries (like Ghana) to identify most frequently occurring and important vaccine related safety issues. PMID- 29172942 TI - Protein quality control is essential for the circadian clock in plants. AB - Extreme environmental conditions, such as heat and cold, often disturb cellular proteostasis, resulting in protein denaturation and oxidative damage that threaten cell viability. Therefore, living organisms have evolved versatile protein quality control mechanisms that clear damaged proteins from cellular compartments. It has been shown that a repertoire of molecular chaperones, including heat shock proteins (HSPs), works together with ubiquitin-proteasome systems in this biochemical process in animals and yeast. However, the protein quality control systems have not been well-characterized in plants. We have recently reported that the E3 ubiquitin ligase ZEITLUPE (ZTL), a central component of the plant circadian clock, constitutes a protein quality control system in conjunction with HSP90, which is responsible for clearing denatured protein aggregates at high temperatures. The ZTL-HSP90 protein complexes are colocalized in insoluble fractions in heat-exposed plants. Notably, lack of ZTL reduces protein polyubiquitination and disrupts the robustness of circadian rhythms under heat stress conditions, providing a novel role of ZTL: it mediates a heat-responsive protein quality control to sustain the clock function. We summarize the potential roles of ZTL in thermal responses and stability of the circadian clock in plants. PMID- 29172943 TI - Tissue Edema, Fluid Balance, and Patient Outcomes in Severe Sepsis: An Organ Systems Review. AB - Severe sepsis and septic shock remain among the deadliest diseases managed in the intensive care unit. Fluid resuscitation has been a mainstay of early treatment, but the deleterious effects of excessive fluid administration leading to tissue edema are becoming clearer. A positive fluid balance at 72 hours is associated with significantly increased mortality, yet ongoing fluid administration beyond a durable increase in cardiac output is common. We review the pathophysiologic and clinical data showing the negative effects of edema on pulmonary, renal, central nervous, hepatic, and cardiovascular systems. We discuss data showing increased morbidity and mortality following nonjudicious fluid administration and challenge the assumption that patients who are fluid responsive are also likely to benefit from that fluid. The distinctions between fluid requirement, responsiveness, and tolerance are central to newer concepts of resuscitation. We summarize data in each organ system showing a predictable increase in morbidity and mortality with nonbeneficial fluid administration, providing a better framework for precision in volume management of the patient with severe sepsis. PMID- 29172944 TI - "Making the Ordinary More Extraordinary": Exploring Creativity as a Health Promotion Practice Among Older Adults in a Community-Based Professionally Taught Arts Program. AB - PURPOSE: Document psychosocial and mental well-being outcomes across artistic mediums and classes of a community-based, professionally taught arts program for older adults. METHOD: One hundred and thirty-eight students completed pre and post class surveys about expectations/experiences when creating art in four mediums (painting, drawing, mixed media, creative writing). In addition, 162 students composed one-paragraph biographical narratives describing their relationships to art and creative engagement. Text was coded for a priori and emergent themes to identify and explain well-being outcomes. FINDINGS: Results of this new study supported and expanded our earlier model of improved psychosocial and mental well-being due to creative engagement: impact of class-cognitive focus and outcome of class-cognitive focus, happiness as component of mental and social well-being due to creative engagement, and robust sense of calmness during the creative process. CONCLUSION: Results suggest that professionally taught arts programming can contribute to well-being and may contribute to brain health through promoting an enhanced ability to focus. Holistic nursing treats creativity as healing, and results suggest that creative engagement should be a priority in therapeutic programming, and individual counseling for older adults to begin engaging in some form of art making suited to their abilities should be incorporated into nursing practice. PMID- 29172945 TI - A phase I, randomized, controlled, dose-ranging study of investigational acellular pertussis (aP) and reduced tetanus-diphtheria-acellular pertussis (TdaP) booster vaccines in adults. AB - Despite high vaccination coverage worldwide, pertussis has re-emerged in many countries. This randomized, controlled, observer-blind phase I study and extension study in Belgium (March 2012-June 2015) assessed safety and immunogenicity of investigational acellular pertussis vaccines containing genetically detoxified pertussis toxin (PT) (NCT01529645; NCT02382913). 420 healthy adults (average age: 26.8 +/- 5.5 years, 60% female) were randomized to 1 of 10 vaccine groups: 3 investigational aP vaccines (containing pertussis antigens PT, filamentous hemagglutinin [FHA] and pertactin [PRN] at different dosages), 6 investigational TdaP (additionally containing tetanus toxoid [TT] and diphtheria toxoid [DT]), and 1 TdaP comparator containing chemically inactivated PT. Antibody responses were evaluated on days 1, 8, 30, 180, 365, and approximately 3 years post-booster vaccination. Cell-mediated immune responses and PT neutralization were evaluated in a subset of participants in pre-selected groups. Local and systemic adverse events (AEs), and unsolicited AEs were collected through day 7 and 30, respectively; serious AEs and AEs leading to study withdrawal were collected through day 365 post-vaccination. Antibody responses against pertussis antigens peaked at day 30 post-vaccination and then declined but remained above baseline level at approximately 3 years post vaccination. Responses to FHA and PRN were correlated to antigen dose. Antibody responses specific to PT, toxin neutralization activity and persistence induced by investigational formulations were similar or significantly higher than the licensed vaccine, despite lower PT doses. Of 15 serious AEs, none were considered vaccination-related; 1 led to study withdrawal (premature labor, day 364; aP4 group). This study confirmed the potential benefits of genetically detoxified PT antigen. All investigational study formulations were well tolerated. PMID- 29172946 TI - Postprandial gut microbiota-driven choline metabolism links dietary cues to adipose tissue dysfunction. AB - The human body is an integrated circuit between microbial symbionts and our Homo sapien genome, which communicate bi-directionally to maintain homeostasis within the human meta-organism. There is now strong evidence that microbes resident in the human intestine can directly contribute to the pathogenesis of obesity and associated cardiometabolic disorders. In fact, gut microbes represent a filter of our greatest environmental exposure - the foods we consume. It is now clear that we each experience a given meal differently, based on our unique gut microbial communities. Biologically active gut microbe-derived metabolites, such as short chain fatty acids, secondary bile acids, and trimethylamine-N-oxide (TMAO), are now uniquely recognized as contributors to obesity and related cardiometabolic disorders. However, mechanistic insights into how microbe-derived metabolites promote obesity are largely unknown. Recent work has demonstrated that the meta organismal production of the bacterial co-metabolite TMAO is linked to suppression of beiging of white adipose tissue in mice and humans. Furthermore, the TMAO pathway is becoming an increasingly attractive therapeutic target in obesity-associated diseases such as type 2 diabetes, kidney failure, and cardiovascular disease. In this commentary we discuss recent findings linking the TMAO pathway to obesity-associated disorders, and provide additional insights into potential mechanisms driving this microbe-host interaction. PMID- 29172947 TI - Crosstalk between WIP and Rho family GTPases. AB - Through actin-binding proteins such as the neural Wiskott-Aldrich syndrome protein (N-WASP) and WASP-interacting protein (WIP), the Rho family GTPases RhoA, Rac1 and Cdc42 are major modulators of the cytoskeleton. (N-)WASP and WIP control Rho GTPase activity in various cell types, either by direct WIP/(N-)WASP/Cdc42 or potential WIP/RhoA binding, or through secondary links that regulate GTPase distribution and/or transcription levels. WIP helps to regulate filopodium generation and participates in the Rac1-mediated ruffle formation that determines cell motility. In neurons, lack of WIP increases dendritic spine size and filamentous actin content in a RhoA-dependent manner. In contrast, WIP deficiency in an adenocarcinoma cell line significantly reduces RhoA levels. These data support a role for WIP in the GTPase-mediated regulation of numerous actin related cell functions; we discuss the possibility that this WIP effect is linked to cell proliferative status. PMID- 29172948 TI - The effect of frailty on HAI response to influenza vaccine among community dwelling adults >= 50 years of age. AB - The immune response to vaccine antigens is less robust in older adults because of changes in the aging immune system. Frailty, the multi-dimensional syndrome marked by losses in function and physiological reserve, is increasingly prevalent with advancing age. Frailty accelerates this immunosenescence but the consequence of frailty on immune response specific to influenza vaccine among older adults, is mixed. An observational, prospective study of 114 adults was conducted in the fall of 2013 to assess the association of physical frailty with immune response to standard dose influenza vaccine in community-dwelling adults >= 50 years of age. Participants were stratified by age (<65 years and >=65 years), and vaccine strain (Influenza A/H1N1, A/H3N2 and B) was analyzed separately adjusting for body mass index (BMI) and baseline log2 hemagglutination inhibition (HAI) titers. Overall, immune responses were lower among those >=65 years of age than those <65 years. Among those >=65 years there were no significant differences between frail and non-frail individuals in seroprotection or seroconversion for any influenza strain. Frail individuals <65 years of age compared with non-frail individuals were more likely to be seroprotected and to seroconvert post vaccination. Linear regression models show the same pattern of significant differences between frail and non-frail for those <65 years but no significant differences between frailty groups for those >=65 years. Additional research may elucidate the reasons for the differences observed between younger frail and non-frail adults. PMID- 29172949 TI - Laparoscopic Versus Open Hepatic Resection for Solitary Hepatocellular Carcinoma Less Than 5 cm in Cirrhotic Patients: A Randomized Controlled Study. AB - BACKGROUND: Current literature is lacking level 1 evidence for surgical and oncologic outcomes of hepatocellular carcinoma (HCC) undergoing laparoscopic versus open hepatectomy. Aim was to compare feasibility, safety, and surgical and oncologic efficiency of laparoscopic versus open liver resection (OLR) in management of solitary small (<5 cm) peripheral HCC in Child A cirrhotic patients. METHODS: Patients were randomly assigned to either OLR group (25 patients) or laparoscopic liver resection (LRR) group (LRR: 25 patients). All were treated with curative intent aiming at achieving R0 resection using radiofrequency-assisted technique. RESULTS: LLR had significantly less operative time (120.32 +/- 21.58 versus 146.80 +/- 16.59 minutes, P < .001) and shorter duration of hospital stay (2.40 +/- 0.58 versus 4.28 +/- 0.79 days, P < .001), with comparable overall complications (25 versus 28%, P = .02). LLR had comparative resection time (66.56 +/- 23.80 versus 59.56 +/- 14.74 minutes, P = .218), amount of blood loss (250 versus 230 mL, P = .915), transfusion rate (P = 1.00), and R0 resection rate when compared with OLR. After median follow-up of 34.43 (31.67-38.60) months, LLR achieved similar adequate oncological outcome of OLR, no local recurrence, with no significant difference in early recurrence or number of de novo lesions (P = .49). One-year and 3-year disease free survival (DFS) rates, 88% and 59%, in the LLR were comparable to corresponding rates of 84% and 54% in OLR (P = .9). CONCLUSION: LLR is superior to the OLR with significantly shorter duration of hospital stay and does not compromise the oncological outcomes. PMID- 29172951 TI - Usability testing of an electronic pain monitoring system for palliative cancer patients: A think-aloud study. AB - Pain experienced by advanced cancer patients is often poorly controlled due to inadequate assessment. We aimed to test an electronic pain monitoring system (PainCheck) with advanced cancer patients and health professionals. In all, 29 participants (13 patients and 16 health professionals (n = 16)) used PainCheck while thinking their thoughts aloud. After the think aloud, both groups were asked about their experiences. Think-aloud and semi-structured interview data were analysed using framework analysis. Both groups were generally positive about PainCheck and found it easy to understand but they had concerns about clinical integration. Their concerns related to impact on workload, how lack of response may affect patient care and ability to engage with and use the technology. PainCheck has the capacity to be useful in clinical practice. For integration to be successful, patients and health professionals need guidance on how to use PainCheck and the expectations of users need to be clarified. PMID- 29172950 TI - The Safety and Feasibility of Three-Dimensional Visualization Technology Assisted Right Posterior Lobe Allied with Part of V and VIII Sectionectomy for Right Hepatic Malignancy Therapy. AB - BACKGROUND: Hepatectomy is the optimal method for liver cancer; the virtual liver resection based on three-dimensional visualization technology (3-DVT) could provide better preoperative strategy for surgeon. We aim to introduce right posterior lobe allied with part of V and VIII sectionectomy assisted by 3-DVT as a promising treatment for massive or multiple right hepatic malignancies to retain maximum residual liver volume on the basis of R0 resection. METHODS: Among 126 consecutive patients who underwent hepatectomy, 9 (7%) underwent right posterior lobe allied with part of V and VIII sectionectomy. 21 (17%) underwent right hemihepatectomy (RH). The virtual RH was performed with 3-DVT, which provided better observation of spatial position relationship between tumor and vessels, and the more accurate estimation of the remnant liver volume. If remnant liver volume was <40%, right posterior lobe allied with part of V and VIII sectionectomy should be undergone. Then, the precut line ought to be planned on the basis of protecting the portal branch of subsegment 5 and 8. The postoperative outcome of patients was compared before and after propensity score matching. RESULTS: Nine patients meeting the eligibility criteria received right posterior lobe allied with part of V and VIII sectionectomy. The variables, including the overall mean operation time, blood transfusion, operation length, liver function, and postoperative complications, were similar between two groups before and after propensity matching. The postoperative first, third, fifth, and seventh days mean value of aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin (ALB), and total bilirubin had no significant difference compared with preoperative value. One patient in each group had recurrence six months after surgery. CONCLUSION: Right posterior lobe allied with part of V and VIII sectionectomy based on 3-DVT is safe and feasible surgery way, and can be a very promising method in massive or multiple right hepatic malignancy therapy. PMID- 29172952 TI - Positive Outcome Expectations and Tobacco Product Use Behaviors in Youth. AB - BACKGROUND: Outcome expectations are an important determinant of health behavior, according to Social Cognitive Theory; yet recent literature has not examined the relationship between outcome expectations and tobacco product use (e.g., use of cigarettes, cigars, hookah, e-cigarettes, or smokeless tobacco). OBJECTIVES: This study examines if outcome expectations at baseline, among an adolescent cohort of never users of tobacco products, predicts tobacco product use (i.e., cigarettes, hookah, e-cigarette, cigar, or smokeless tobacco) or susceptibility to use at 6 month follow-up. METHODS: Data are from the first two waves of a Texas cohort study of urban middle school and high school students, which were collected in 2014-2015. Logistic regression analyses were used; these adjusted for socio demographic variables. Analyses were limited to never users of any tobacco product at baseline (n = 1999, N = 357,035). RESULTS: Outcome expectations related to stress relief predicted ever use of (AOR: 4.21, 95% CI 1.84-9.60) and susceptibility (AOR: 2.97, 95% CI 1.01-8.70) to tobacco products. Additional outcome expectations (e.g., relaxation, concentration, slimness, etc.) were not associated with ever use or susceptibility. Conclusions/Importance: This study extends the literature regarding outcome expectations among adolescents regarding tobacco products. It is important that interventions offer alternative solutions to stress relief that do not include tobacco products. PMID- 29172953 TI - Cortactin function in invadopodia. AB - Actin remodeling plays an essential role in diverse cellular processes such as cell motility, vesicle trafficking or cytokinesis. The scaffold protein and actin nucleation promoting factor Cortactin is present in virtually all actin-based structures, participating in the formation of branched actin networks. It has been involved in the control of endocytosis, and vesicle trafficking, axon guidance and organization, as well as adhesion, migration and invasion. To migrate and invade through three-dimensional environments, cells have developed specialized actin-based structures called invadosomes, a generic term to designate invadopodia and podosomes. Cortactin has emerged as a critical regulator of invadosome formation, function and disassembly. Underscoring this role, Cortactin is frequently overexpressed in several types of invasive cancers. Herein we will review the roles played by Cortactin in these specific invasive structures. PMID- 29172954 TI - AMPK and autophagy control embryonic elongation as part of a RhoA-like morphogenic program in nematode. AB - Autophagy is the process where cytosolic components are digested by the cell. This process is required for cell survival in stressful conditions. It was also shown to control cell division and more recently, cell morphology and migration. We characterized signalling pathways enabling embryonic epidermal cells of the nematode Caenorhabditis elegans to elongate along their antero-posterior axis. Previous studies revealed that epidermal cells can adopt either a RhoA-like or a Rac1-like morphogenic program. We show here that the AMP-activated protein kinase (AMPK) and genes controlling autophagy are required for proper elongation of epidermal cells following the RhoA-like program and are dispensable for other cells. This suggests that AMPK-autophagy is used by the embryo to fuel the most energy-demanding morphogenic processes promoting early elongation.

AB - PURPOSE: Children often experience the uncomfortable effects of invasive procedures as a part of primary care and during times of illness. Holistic comfort has been well documented in adult literature but little research exists on the understanding of holistic procedural comfort from the child's perspective. In this study, holistic comfort related to an invasive venipuncture procedure was explored in children age 5 to 7 years and their caregivers of all ages. DESIGN: A qualitative descriptive design described by Sandelowski was used. METHOD: The philosophical underpinnings of naturalistic inquiry of Guba and Lincoln were used. Semistructured interviews were conducted with 13 child and 15 caregiver participants. Children also drew pictures to help describe their perceptions. FINDINGS: Traditional thematic content analysis described by Hsieh and Shannon yielded four overarching themes of holistic comfort related to venipuncture procedures in children: Body Comfort, Cognitive and Emotional Comfort, Comfort in the Procedure Surroundings, and Comfort Play. CONCLUSIONS: Numerous recommendations for future research are included. Implications for nursing and related health sciences, organizational and administrative policy, invasive procedures, theory, and methods were found and are discussed. Findings from this study will assist nurses in providing procedure management for children from a holistic care perspective.

AB - Despite evidence that estrogens and insulin are related to type 1 endometrial carcinoma (EC), their synergistic role has not been analyzed. Here, we investigated how estrogens cooperate with insulin to promote type 1 EC progression. We examined the clinical significance of serum estrogen and insulin levels using type 1 EC patients and control subjects. Univariate and multivariate logistic regression analyses for total, premenopausal, and postmenopausal subjects were performed. Type 1 EC risk was evaluated with respect to estrone, estradiol, and insulin levels based on odds ratios (ORs) using stratified data. Cell growth in vitro and in vivo, effects of insulin and estradiol on apoptosis and cell cycle distribution were measured after estradiol and insulin stimulation. Estrone and insulin concentrations were significantly high in type 1 EC patients and retained positive associations with type 1 EC after adjustment for BMI, WHR, diabetes, and hypertension. The odds ratio was significantly high for type 1 EC patients with higher levels of estrone/estradiol and insulin than for patients with higher levels of either estrone/estradiol or insulin, suggesting that estrogen and insulin play a synergistic role in type 1 EC carcinogenesis and progression. Compared to EC cells and cell-based xenografts treated with estradiol or insulin alone, those treated with estradiol and insulin exhibited stronger stimulation. Estrogen and insulin play synergistic roles in type 1 EC carcinogenesis and progression, extending our understanding of EC risks.

AB - OBJECTIVE: Lifestyle (smoking, drinking alcohol) and body mass index (BMI) predictors of successful outcomes in assisted reproductive technology (ART) treatments were examined in this meta-analysis. METHOD: A bibliographic search was undertaken using six databases. The review was informed by PRISMA/MOOSE guidelines. Meta-analytic data were analysed using random effects models. RESULTS: We included 77 studies examining effects of BMI, smoking and drinking alcohol. Patients with a BMI< =24.9 were significantly more likely to achieve LB/pregnancy than with BMI> =25 OR = 1.219 (95% CI:1.128-1.319, z = 4.971, p < .001; I2 = 53.779%, p = .001). Non-smokers were significantly more likely to achieve a LB or pregnancy than smokers OR = 1.457 (95% CI:1.228-1.727, z = 4.324, p < .001; I2 = 51.883; p = .001). Meta-regression revealed the number of embryos transferred significantly moderated the effects of smoking on ART outcomes, and there was a trend indicating primary infertility and high BMI were also significant moderators. The evidence for drinking alcohol was inconclusive due to the small number of studies. CONCLUSIONS: This meta-analysis confirms that ART treatment success can be predicted with lifestyle factors. Further, non-smokers' relative odds of pregnancy/live birth increase as more embryos were transferred but there was a trend that the odds of pregnancy/live birth decrease with primary infertility and high BMI.

AB - PURPOSE: The purpose of this study was to elicit participants' ( N = 16) perceptions of a gardening activity at a juvenile justice center and to determine whether past exposure to gardening and farmers markets was associated with their perceptions of the gardening experience. DESIGN: This cross-sectional, exploratory program evaluation was conducted in partnership with the Kentucky Department of Juvenile Justice. Adolescents completing the Cadet Leadership and Education Program participated in gardening in order to provide produce to a local farmers' market. METHOD: After the growing season, participants were asked to complete a nine-item questionnaire about the gardening activity during one of their usual classes at the facility. The questionnaire assessed perception of the experience and past exposure to gardening and farmers' markets. FINDINGS: Participants reported favorably about their participation in the activity, knowledge gained from the activity, and their intent to garden in the future. Those who had previously gardened had more favorable perception of gardening than those who had never gardened. Gardening is an inexpensive means of teaching teamwork and delayed gratification and providing a sense of empowerment and may benefit at-risk adolescents during incarceration. PMID- 29172960 TI - Pantarsal arthrodesis in cats using orthogonal plating. AB - Case series summary Pantarsal arthrodesis (PTA) was performed in seven tarsi of six cats, using orthogonal (dorsal and medial) veterinary cuttable plates (VCPs) without postoperative external coaptation. Short-term outcomes, arthrodesis progression and complications were assessed using a retrospective review of case notes (veterinary examination) and radiographs. Long-term outcomes were assessed via owner questionnaire (Feline Musculoskeletal Pain Index [FMPI]). Mean angle of PTA was 136 degrees (range 116-166 degrees ). Intraoperative complications were recorded in two cases, both involving failure of the drill bit during drilling for calcaneotibial screws. Postoperative complications were encountered in a case of bilateral single-session PTA. These included gastrocnemius myotendinopathy on the right, and long-term protrusion of a screw head from the skin on the left. Both complications were resolved surgically, through resection of the implicated gastrocnemius tendon of insertion and removal of the plate, respectively. FMPI assessment was performed for all six cats a mean of 8.8 months (range 6-16 months) following surgery. Mean score for the first part (assessing ability to perform normal activities) was 92.2% (range 80.9-97.1%). Mean score for the second part (owner perception of pain) was 95.8% (range 87.5-100%). Mean overall score (mean score for parts 1 and 2 combined) was 92.3% (range 81.6-97.4%). PTA may be performed in cats using orthogonal VCPs to treat severe tarsal injuries. It may be prudent to avoid single-session bilateral PTA in cats. Relevance and novel information This case series documents a novel technique as an alternative for PTA in cats with talocrural injuries. Long-term outcome and complications presented in this case series are evaluated and discussed.

AB - Given the importance of addressing multiplicity issues in confirmatory clinical trials, several recent publications focused on the general goal of identifying most appropriate methods for multiplicity adjustment in each individual setting. This goal can be accomplished using the Clinical Scenario Evaluation approach. This approach encourages trial sponsors to perform comprehensive assessments of applicable analysis strategies such as multiplicity adjustments under all plausible sets of statistical assumptions using relevant evaluation criteria. This two-part paper applies a novel class of criteria, known as criteria based on multiplicity penalties, to the problem of evaluating the performance of several candidate multiplicity adjustments. The ultimate goal of this evaluation is to identify efficient and robust adjustments for each individual trial and optimally select parameters of these adjustments. Part I deals with traditional problems with a single source of multiplicity. Two case studies based on recently conducted Phase III trials are used to illustrate penalty-based approaches to evaluating candidate multiple testing methods and constructing optimization algorithms. PMID- 29172962 TI - Treatment of mature landfill leachate using hybrid processes of hydrogen peroxide and adsorption in an activated carbon fixed bed column. AB - In this study, the treatment of mature landfill leachate is evaluated by oxidation with hydrogen peroxide (H2O2) combined with adsorption in a granular activated carbon (GAC) fixed bed column to determinate the increase in the biodegradability index, the reduction of chemical oxygen demand (COD) as well as the increase in the useful life of the GAC bed. The sample leachate from Loma de Los Cocos Landfill (Cartagena de Indias, Colombia) has a very low biodegradability ratio ranging from 0.034 to 0.048 that makes it difficult to meet the required water quality level according to the regulations. The COD removal is initially monitored in the H2O2 oxidation treatment process. The operating conditions such as pH, H2O2 dosage, and the reaction time are optimized in this process based on the percentage of COD removal. A maximum COD removal of 29.9% is achieved at an initial H2O2 concentration of 5000 mg L-1 with a pH of 8 and the reaction time of 60 min. The hybrid treatment by H2O2-GAC achieved 97.3% COD removal and 116% increase in the biodegradability ratio (from 0.072 to 0.134) while this ratio was increased by 6.5% with H2O2 alone. Moreover, the useful life of the GAC bed is increased from 45 min in the column fed with raw leachate to 170 min in the column fed with pretreated leachate and 5000 mg L-1 of H2O2 at pH of 8 that subsequently increased the activated carbon adsorption capacity. An adsorption model for leachate treated with H2O2 is also developed. PMID- 29172963 TI - Effect of administration rate on propofol requirement in cats. AB - Objectives The objective of this study was to determine the effect of administration rate on propofol dose for induction of anesthesia and the effect of methadone on this dose. Methods This was a prospective, randomized, blinded clinical study. Forty male cats (mean +/- SD age 1.5 +/- 0.8 years) were admitted for orchiectomy. Cats were randomly allocated to receive acepromazine (0.05 mg/kg) with either methadone (MET; 0.3 mg/kg) or saline (SAL; 0.03 ml/kg). Each premedication group then received anesthetic induction with propofol at 5 (F) or 1.5 mg/kg/min (S), resulting in the following four groups: MET-F, SAL-F, MET-S and SAL-S. Sedation scores were assigned at 15 and 30 mins after premedication using a simple descriptive scale (SDS) and a visual analog scale (VAS). After assignment of sedation scores, respiratory frequency ( fR) was recorded, and anesthetic induction began and was continued until cats lost their palpebral reflexes and jaw tone, and the eye globe rotated ventromedially. The time for induction and the total amount of propofol needed was recorded, and intubation was then performed. After intubation, fR was also recorded. Results SDS and VAS sedation scores were low at 15 and 30 mins after premedication. There was no significant difference in sedation scores by time or between the groups at any time on any scale. The amount of propofol needed to achieve anesthetic induction was 5.3 +/- 1.1 mg/kg in group MET-F, which was statistically lower when compared with the other three groups, which demonstrated no difference among them. Conclusions and relevance Premedication with acepromazine and methadone was not able to produce adequate sedation in healthy cats. The slow induction rate is not adequate for use in cats considering that all of the animals demonstrated excitement during anesthetic induction. The fast administration rate was able to produce adequate induction of anesthesia and reduce the amount of propofol needed to achieve intubation only when using methadone.

AB - Surface sediment samples were collected from the Pacific sector of the Arctic Ocean during the 6th Chinese National Arctic Research Expedition (CHINARE), 2014. Concentrations and extractabilities of six toxic metals (Cd, Cr, Cu, Ni, Pb, and Zn) were determined using a modified sequential extraction procedure as described by the European Community Bureau of Reference (BCR). A new analytical hierarchy approach to risk assessment, involving sediment quality guidelines and risk assessment codes, is described for metals in marine sediments from the Arctic Ocean. Results indicate a mobility order of Pb > Cd > Cu > Zn > Ni > Cr with mean liable fraction (F1+F2+F3) being 83.0%, 81.6%, 62.0%, 47.1%, 42.1%, and 15.6%, respectively. Ni presents the most serious ecological risk in the study area, with most samples (93.9%) indicating medium risk, followed by Cu (54.5%) and Zn (27.3%). For Ni and Zn, there are also samples showing high ecological risk (Ni at site NB02, northern Bering Sea; Zn at R07, northern Chukchi Sea). The ecological risk for Cr indicates low ecological risk (93.9%) and some medium risk (6.1%). All Cd assessments indicate low ecological risk, while most Pb assessments indicate zero (33.3%) to low risk. The new ecological risk assessment method improves on assessments based on metal mobility or concentration alone. PMID- 29172966 TI - Antiquorum Sensing Activity of Seed Oils from Oleaginous Plants and Protective Effect During Challenge with Chromobacterium violaceum. AB - Seed oils from oleaginous plants are rich in fatty acids (FAs) that play important roles in the health of the consumers. Recent studies indicate that FA also can play an important role in communication and regulation of virulence in bacteria. Nevertheless, evidence demonstrating protection against bacterial infections mediated by their quorum sensing inhibition (QSI) activity is scarce. In this study, sunflower, chia, and amaranth oils, were assayed for their QSI capacity by inhibiting violacein production and alkaline exoprotease activity of Chromobacterium violaceum. In vitro assays revealed that the oils exhibited QSI activities, whereas in vivo they delayed death of mice inoculated intraperitoneally with the bacterium. Gas chromatography coupled with mass spectrometry analysis of the oils indicated the presence of saturated FA (SAFA) and unsaturated FA as main components. Through a structure-activity relationship study of free FAs, bactericidal effect was identified mainly for polyunsaturated FAs, whereas QSI activity was restricted to SAFA of chains 12-18 carbon atoms in length. These data correlate with a possible interaction suggested by molecular docking analysis of lauric, myristic, and stearic acids with the CviR protein. Our study highlights the antiquorum sensing potential of SAFA, which may be future antivirulence therapeutic agents for the treatment of bacterial infections. PMID- 29172968 TI - The sensitivity of soil enzymes, microorganisms and spring wheat to soil contamination with carfentrazone-ethyl. AB - Herbicides pose a significant threat to the natural environment, in particular in soils that are most exposed to plant protection agents. Prolonged herbicide use leads to changes in soil metabolism and decreases soil productive potential. In this study, the influence of carfentrazone-ethyl (CE) on the microbiological and biochemical properties of soil and the yield of Triticum aestivum L. was evaluated. Carfentrazone-ethyl was applied to sandy loam (pHKCl - 7.0) in doses of 0.000, 0.264, 5.280, 10.56, 21.18, 42.24, 84.48 and 168.96 ug kg-1 DM soil. Soil samples were subjected to microbiological and biochemical analyses on experimental days 30 and 60. Carfentrazone-ethyl disrupted the biological equilibrium in soil by decreasing the abundance and biodiversity of soil-dwelling microorganisms, the activity of soil enzymes, the values of the biochemical activity indicator and spring wheat yields. Carfentrazone-ethyl had the most adverse effects when applied in doses many fold higher than those recommended by the manufacturer. The toxic effects of CE were also determined by its soil retention time. Soil treated with CE was characterized by higher counts of oligotrophic bacteria, organotrophic bacteria, bacteria of the genus Azotobacter, actinomycetes and fungi on day 60, and spore-forming oligotrophic bacteria on day 30. The activity of dehydrogenases, urease, alkaline phosphatase and beta glucosidase was higher on day 30 than on day 60. PMID- 29172967 TI - A comprehensive analysis of Italian web pages mentioning squalene-based influenza vaccine adjuvants reveals a high prevalence of misinformation. AB - Squalene-based adjuvants have been included in influenza vaccines since 1997. Despite several advantages of adjuvanted seasonal and pandemic influenza vaccines, laypeople's perception of such formulations may be hesitant or even negative under certain circumstances. Moreover, in Italian, the term "squalene" has the same root as such common words as "shark" (squalo), "squalid" and "squalidness" that tend to have negative connotations. This study aimed to quantitatively and qualitatively analyze a representative sample of Italian web pages mentioning squalene-based adjuvants used in influenza vaccines. Every effort was made to limit the subjectivity of judgments. Eighty-four unique web pages were assessed. A high prevalence (47.6%) of pages with negative or ambiguous attitudes toward squalene-based adjuvants was established. Compared with web pages reporting balanced information on squalene-based adjuvants, those categorized as negative/ambiguous had significantly lower odds of belonging to a professional institution [adjusted odds ratio (aOR) = 0.12, p = .004], and significantly higher odds of containing pictures (aOR = 1.91, p = .034) and being more readable (aOR = 1.34, p = .006). Some differences in wording between positive/neutral and negative/ambiguous web pages were also observed. The most common scientifically unsound claims concerned safety issues and, in particular, claims linking squalene-based adjuvants to the Gulf War Syndrome and autoimmune disorders. Italian users searching the web for information on vaccine adjuvants have a high likelihood of finding unbalanced and misleading material. Information provided by institutional websites should be not only evidence-based but also carefully targeted towards laypeople. Conversely, authors writing for non institutional websites should avoid sensationalism and provide their readers with more balanced information. PMID- 29172969 TI - Interleukin-35 Modulates the Imbalance Between Regulatory T Cells and T Helper 17 Cells in Enterovirus 71-Induced Hand, Foot, and Mouth Disease. AB - Interleukin (IL)-35 modulates the imbalance between regulatory T cells (Tregs) and T helper (Th) 17 cells, which played vital roles in the pathogenesis of autoimmune and infectious diseases. However, the role of Tregs/Th17 cell imbalance and the regulatory functions of IL-35 have remained largely unknown in enterovirus 71 (EV71)-induced hand, foot, and mouth disease (HFMD). In this study, a total of 47 HFMD patients (30 with mild HFMD and 17 with severe HFMD) and 13 healthy individuals were enrolled. The frequencies of CD4+CD25+CD127dim/- Tregs and CD4+IL-17+ Th17 cells, as well as IL-35 expression levels, were measured. Cellular proliferation and cytokine production was also determined in purified Tregs following recombinant IL-35 stimulation. An imbalance between Tregs and Th17 cells was observed in children with severe HFMD, which manifested as a reduction in the Tregs population and an elevation in the Th17 population. Serum IL-35 concentrations were also decreased in case of severe HFMD, which correlated with the Tregs:Th17 cell ratios. Recombinant IL-35 stimulation increased the proportion of Tregs, but downregulated that of Th17 cells. Treatment with IL-35 enhanced Tregs suppressive function and IL-35 and IL-10 expression, but reduced IL-22 secretion in both healthy individuals and those with severe HFMD. The Tregs:Th17 cell ratio was increased in the convalescent patients, however, a significant reduction in serum IL-35 was not observed. Our findings indicated that EV71 infection shifted the Tregs:Th17 cell ratio through IL-35 by downregulating inhibitory cytokine production and reducing the cell-to cell contact inhibition of effector T cells. Regulation of IL-35 as it relates to the Tregs/Th17 balance may play a critical role in the pathogenesis of EV71 associated HFMD. PMID- 29172970 TI - Bayesian design for two-arm randomized Phase II clinical trials with endpoints from the exponential family using multiple constraints. AB - Frequentist design for two-arm randomized Phase II clinical trials with outcomes from the exponential dispersion family was proposed previously, where the total sample sizes are minimized under multiple constraints on the standard errors of the estimated group means and their difference. This design was generalized from an approach specific for dichotomous outcomes. The two previous approaches measure the central tendency of each group and treatment effect based on mean and difference in means. Other measures such as median or hazard ratio are more appropriate under certain situations. In addition, the frequentist approaches assume that unknown parameters are fixed values. This does not reflect the reality that uncertainty always exists for unknowns. Compared to the frequentist methods, the Bayesian approach offers a flexible way to measure central tendency and treatment effect, and incorporate uncertainty in parameters of interest into considerations. In this article, we generalize a Bayesian design for Phase II clinical trials with endpoints in the exponential family from the two previously developed frequentist approaches. The proposed design minimizes the total sample sizes under pre-specified constraints on the expected length of posterior credible intervals for measures of treatment effect and central tendency in each group. The design is applicable for trials with fixed or optimal randomization allocation ratio and can be applied under adaptive procedure. Examples of method implementations are provided for different types of endpoints from the exponential family in both fixed and adaptive settings. PMID- 29172971 TI - Physical Activity and Sedentary Behaviors Levels of Kuwaiti Adolescents: The Study of Health and Activity Among Adolescents in Kuwait. AB - BACKGROUND: There is only scarce number of studies available describing the lifestyle of adolescents living in Arab countries. Hence, we described physical activity (PA) and sedentary behaviors patterns among Kuwaiti adolescents and the associations with parental education. METHODS: Cross-sectional data from 435 adolescents (201 boys and 234 girls) were collected from the Study of Health and Activity among Adolescents in Kuwait conducted between 2012 and 2013. Outcome variables included PA (ActiGraph GT1M accelerometers) and sedentary behaviors. Exposure variable was parental education. Descriptive and multiple logistic regression analyses were used to examine the association between parental education and outcome variables. RESULTS: Total sedentary time (minutes per day) was higher in girls [568.2 (111.6)] than in boys [500.0 (102.0)], whereas boys accumulated more minutes in light, moderate, and vigorous PA (all Ps <= .001). In total, 3.4% of adolescents spent >=60 minutes per day of moderate to vigorous PA (by accelerometry), while only 21% met the screen time guidelines. Low/medium maternal education was associated with a higher odds of exceeding screen time guidelines (odds ratio = 2.09; 95% confidence interval, 1.09-4.02). CONCLUSIONS: Most Kuwaiti adolescents in this sample were physically inactive and exceeded screen time guidelines. Objective PA was not socially patterned, yet an inverse association between maternal education and screen time behaviors was found. PMID- 29172972 TI - Choosing Doctors Wisely: Can Assisted Choice Enhance Patients' Selection of Clinicians? AB - We conducted a simulated clinician-choice experiment, comparing choices and decision-making processes of participants ( N = 688) randomized among four experimental arms: a conventional website reporting only quantitative performance information, a website reporting both qualitative (patient comments) and quantitative information, the second website augmented by a decision aid (labeling of patient comments), and the decision-aided website further augmented by the presence of a trained navigator. Introducing patient comments enhanced engagement with the quality information but led to a decline in decision quality, particularly the consistency of choices with consumers' stated preferences. Labeling comments helped erase the decline in decision quality, although the highest percentage of preference-congruent choices was seen in the navigator arm. Engagement with the quality information and satisfaction with choices available were likewise highest in the navigator arm. Findings held for high- and low skilled decision makers. Thus, navigator assistance may be a promising strategy for equitably promoting higher quality choices in information-rich contexts. PMID- 29172973 TI - Ezetimibe Use and LDL-C Goal Achievement: A Retrospective Database Analysis of Patients with Clinical Atherosclerotic Cardiovascular Disease or Probable Heterozygous Familial Hypercholesterolemia. AB - BACKGROUND: Ezetimibe is recommended by clinical practice guidelines as a second line therapy for lowering low-density lipoprotein cholesterol (LDL-C) levels, but little is known about its use and effectiveness in real-world populations. OBJECTIVE: To understand the real-world impact of adding or switching to ezetimibe on LDL-C goal achievement in patients with clinical atherosclerotic cardiovascular disease (ASCVD) and/or heterozygous familial hypercholesterolemia (HeFH). METHODS: Patients aged >= 18 years with an LDL-C measurement available between January 1, 2013, and June 30, 2014, were identified using the Inovalon MORE 2 database; this included commercial, health insurance exchange, Medicare Advantage, and managed Medicaid patients. The index date was the date of the first LDL-C measurement. Patients were required to have evidence of clinical ASCVD or probable HeFH based on ICD-9-CM codes and >= 1 outpatient pharmacy claim for a statin in the 1-year pre-index period, as well as continuous medical and pharmacy coverage for 1 year pre- and post-index. Patients who added ezetimibe to existing statin therapy or switched to ezetimibe within 90 days post-index LDL-C measurement were identified in order to replicate the typical time a clinician takes to assess the use of ezetimibe. The primary outcome was the proportion of patients who met the LDL-C goal of < 70 mg/dL within the follow-up period. LDL-C goal achievement was evaluated by baseline LDL-C level groupings: < 70 mg/dL, 70 99 mg/dL, 100-129 mg/dL, or >= 130 mg/dL; and across 4 patient diagnosis categories: all patients, ASCVD only, probable HeFH only, and ASCVD and probable HeFH. Descriptive analyses were reported. Categorical variables were summarized as the number of and corresponding percentage of patients. Continuous variables were presented as the mean and SD of the number of observations and median and range where appropriate. RESULTS: Of 125,330 patients who met selection criteria, mean age was 70.1 (SD = 9.9) years and mean LDL-C baseline was 90.7 (SD = 34.0) mg/dL. Over one half of patients (70%) were receiving statin therapy. Within the post-index time frame, 1.05% (n = 1,309) of patients added or switched to ezetimibe. Of these, 26% achieved LDL-C goal during the 90-day follow-up (59.5% did not achieve goal and 14.4% did not have a follow-up lab value). Therapeutic targets were reached by 30% of patients with baseline LDL-C levels of 70-99 mg/dL; 14% of those with baseline LDL-C of 100-129 mg/dL; and 7% of those with baseline LDL-C of >= 130 mg/dL. Achievement of LDL-C goals also varied by baseline diagnosis category. CONCLUSIONS: The addition of or switch to ezetimibe therapy was associated with a relatively small percentage of LDL-C goal achievement (< 70 mg/dL) in patients with clinical ASCVD and/or HeFH, even among patients with baseline LDL-C between 70 and 99 mg/dL. To provide superior individualized care for patients with hyperlipidemia, there is a potential role for newer therapies in lipid lowering, such as PCSK9 inhibitors, in appropriate high-risk populations.

PMID- 29172974 TI - Following the Biosimilar Breadcrumbs: When Health Systems and Manufacturers Approach Forks in the Road. AB - : Over 2 years have passed since the first biosimilar was approved for use in the United States. Despite a relatively slow start, biosimilar activity has significantly increased in recent months. Biologics are the most expensive drug category in the United States, costing patients hundreds or even thousands of dollars per year. Biosimilars have the potential to significantly decrease cost of care, increase access, and improve patient outcomes. In order to realize the potential savings, biosimilar manufacturers, health care providers, and payers must develop strategies to navigate the challenging health care environment and understand where and how biosimilars bring the most value to patients. Trends in biosimilar uptake within health systems have demonstrated the need for manufacturers to deploy a robust product strategy before and after launch. In order to gain high-level insight from health system experiences with the first infliximab biosimilar approved in the United States, a questionnaire was distributed to pharmacy representatives from health systems during March and April 2017. Responses from more than 50 health systems across the country revealed that the key barriers and challenges faced with biosimilar uptake include payers and reimbursement, interchangeability, provider preference, and cost. This article explores health system experiences with biosimilars thus far and describes real-world implementation strategies. In addition, insights into manufacturer considerations are highlighted with regard to financial, clinical, and operational decisions. DISCLOSURES: The author received no outside funding support and has nothing to disclose. PMID- 29172975 TI - A Systematic Review of U.S. Biosimilar Approvals: What Evidence Does the FDA Require and How Are Manufacturers Responding? AB - BACKGROUND: Biosimilars undergo an abbreviated licensure pathway called 351(k), which was created by the Biologics Price Competition and Innovation Act of 2009. This approval process is different from the 351(a) pathway for original biologic approval and, as of August 2017, has been used to approve 5 biosimilars in the United States. OBJECTIVE: To identify the types and quantities of evidence required by the FDA for biosimilar approval and the corresponding evidence manufacturers have provided in their 351(k) biosimilar approval applications. METHODS: To collect data for this review, we searched through drug-specific FDA approval documents and approval-related FDA webcasts for approval indications and dates; reference product names; formulations; postmarketing requirements and commitments; evidence used for extrapolation claims; advisory committee votes; and evidence on similarity in analytical and functional characteristics, pharmacokinetics, pharmacodynamics, efficacy, safety, and immunogenicity. RESULTS: All biosimilars approved in the United States provided a large evidence base to demonstrate similarity in analytical and functional characteristics-3 to 5 clinical studies showed similarity in pharmacokinetics and pharmacodynamics, and 1 to 2 clinical studies demonstrated efficacy. Safety and immunogenicity were evaluated across all clinical studies. All biosimilars were compared with either the U.S.-licensed reference product or the reference product licensed by the European Union. Extrapolation allowed biosimilars to be approved for indications in which clinical studies were not conducted. The few indications for which biosimilars did not share approval with the reference product were due to market exclusivity protection. None of the 5 biosimilars have been approved as interchangeable in the United States. CONCLUSIONS: The approval process for the first 5 biosimilars on the market in the United States provides a baseline understanding of what type and degree of evidence is required for biosimilar approval.

PMID- 29172977 TI - Conversion from Filgrastim to Tbo-filgrastim: Experience of a Large Health Care System. AB - BACKGROUND: In 2008, tbo-filgrastim was approved as a biosimilar in Europe and then approved in the United States by the FDA in 2012 as a biologic product with 1 similar indication to filgrastim. Because tbo-filgrastim was less expensive than filgrastim, and clinical information and expert opinion supported similarity, the Pharmacy & Therapeutics Committee of a large health care system approved tbo-filgrastim as the preferred granulocyte-colony stimulating factor (G CSF) product in March 2014. OBJECTIVES: To (a) assess the use of filgrastim and tbo-filgrastim products by comparing baseline characteristics, setting of care, indication for use, and payer type and (b) understand potential barriers of conversion to tbo-filgrastim. METHODS: A retrospective evaluation of filgrastim and tbo-filgrastim use was conducted on all patients (N = 204) who received the drugs between July 2015 and December 2015 at the 2 largest hospitals in the health system. Baseline characteristics, indication requiring use of filgrastim or tbo-filgrastim, setting of care, and payer information were collected from electronic medical records, and descriptive analyses were conducted. RESULTS: Overall, G-CSFs were administered to 204 patients for 261 episodes of care (filgrastim and tbo-filgrastim were used in 65 and 196 episodes of care, respectively). Baseline characteristics were similar between the 59 patients who received filgrastim and the 174 patients who received tbo-filgrastim. G-CSF was primarily used in the inpatient setting (163 episodes of care, 63%) with 90% of patients using tbo-filgrastim. In the outpatient setting (98 episodes of care, 38%), filgrastim and tbo-filgrastim were each used by 50% of patients. Tbo filgrastim was the preferred G-CSF by clinical providers for all indications, except for stem cell mobilization, where filgrastim use was higher (55% vs. 45% of 71 episodes of care). In the outpatient setting, analysis by payers showed that the majority of patients on commercial plans were using filgrastim (58%), while half of Medicare patients were using filgrastim (50%, n = 12). Twelve patients were self-paid, and all were using tbo-filgrastim. Subgroup analysis by hospital showed differences in utilization patterns. CONCLUSIONS: Although tbo filgrastim was the preferred G-CSF in our formulary, 29% of patients continued to receive filgrastim. Conversion to tbo-filgrastim has been largely successful, but extra steps may be needed to achieve full conversion to biosimilars. DISCLOSURES: No outside funding supported this study.

PMID- 29172978 TI - Application of the FDA Biosimilar Extrapolation Framework to Make Off-Label Determinations. AB - BACKGROUND: The FDA's extrapolation framework allows for a biosimilar to obtain licensure for indications that were not explicitly studied in the context of a clinical trial by extending conclusions from studies in 1 population to make inferences in other populations. Within routine clinical care, drugs and biologics are routinely used for medically accepted off-label indications. The appropriateness of these products for off-label indications are typically curated by compendia and guidelines, which have established processes and criteria for reviewing and evaluating the evidence to make such determinations. The evidence paradigm for biosimilars is different from originator biologics and is one of comparability to a reference product, not to reestablish clinical benefit. Thus, this paradigm shift can be applied to the exercise of making off-label determinations for biosimilars, and the FDA's framework of extrapolation can be used by clinicians and coverage policy decision makers to determine appropriate off-label indications for biosimilars. OBJECTIVE: To highlight how the FDA's biosimilar extrapolation framework can be used to make off-label policy decisions, using to 2 approved biosimilars for filgrastim and infliximab as case studies. METHODS: This study describes the FDA extrapolation framework for evaluating whether there are any differences in the mechanism of action, pharmacokinetics/biosdistribution, immunogenicity, and toxicity between on-label and off-label indications. Two case studies are presented that evaluate the biosimilars filgrastim-sndz and infliximab-dyyb for the offlabel indications of treating symptomatic anemia in patients with myelodysplastic syndromes and immune mediated colitis, respectively. The analytical, nonclinical, and clinical pharmacology, along with clinical studies demonstrating that filgrastim-sndz and infliximab-dyyb are biosimilar to their respective reference products, are reviewed and discussed in context with the extrapolation framework to ascertain whether use of the biosimilar within the off-label indications is scientifically justified. RESULTS: The mechanism of action of filgrastim and infliximab between their FDA-approved and off-label indications are the same. In addition, there is a high degree of similarity with the analytical and nonclinical characteristics of filgrastim-sndz and infliximab-dyyb and their respective reference products. There is no expectation of differences in safety and immunogenicity across the patient populations. Thus, some decision makers may determine that filgrastim sndz and infliximab-dyyb be used for the off-label indications of treating symptomatic anemia in patients with myelodysplasia and immune-mediated colitis, respectively. CONCLUSIONS: In some cases, the use of biosimilars for off-label indications can be scientifically justified. Since coverage policy decisions are intimately tied to compendia and guideline listings, it is incumbent upon these groups to conduct formal assessments of biosimilar off-label indications using the FDA extrapolation framework.

PMID- 29172979 TI - Pharmacovigilance of Biologics in a Multisource Environment. AB - : It is important that systems are in place to ensure that appropriate and comprehensive records are kept for use of all medications. It is fundamental to an effective pharmacovigilance system that patient medical records contain sufficient information to identify which medication has been prescribed, when it was administered, and at what dose. The availability of biologics from multiple sponsors has raised questions by some health care providers about the ability of current pharmacovigilance systems to trace specific biologics. In this article, periodic safety update reports were used to assess current postapproval safety monitoring for 3 biosimilars (epoetin alfa, somatropin, and filgrastim) that collectively represented nearly 350 million patient days of treatment worldwide. The reference products have each been marketed for over 10 years, forming a strong baseline of postmarketing safety data against which the safety of biosimilars can be compared. Published data from Denmark were also reviewed as additional evidence of how current pharmacovigilance systems are able to attribute adverse events to particular medicines. Collectively, the data show that spontaneous adverse drug reactions are reported by brand name in the majority of cases and are attributable to a specific medicine. Also discussed are the informational elements critical to monitoring biologics, or indeed any medicine, to ensure the availability of complete information so medicines that a patient has received can be quickly identified should a safety event occur. We support the addition of a single data element, the batch/lot number, to enhance the value of current pharmacovigilance systems. Adoption of 2-D barcodes in the European Union (EU) and standardized numerical identifiers in the United States addresses this need, since they include batch/lot numbers. These identifiers are already being implemented in the United States and the EU to improve patient safety, reduce medication errors, facilitate anticounterfeiting, and enable effective product recalls and adverse event reporting. Importantly, electronic identifiers will ameliorate safety reporting concerns with respect to biosimilars, while concurrently achieving these much broader public health objectives through more complete pharmacovigilance data.

PMID- 29172980 TI - High-Cost Sarcoidosis Patients in the United States: Patient Characteristics and Patterns of Health Care Resource Utilization. AB - BACKGROUND: Sarcoidosis is a multisystem inflammatory disorder characterized by the presence of noncaseating granulomas in involved organs. Prior research has found that sarcoidosis imposes a significant economic burden to U.S. payers. However, the drivers of high health care costs among sarcoidosis patients are unknown. OBJECTIVE: To characterize sarcoidosis patients who were among the top 20% of total health care costs. METHODS: Patients with a first diagnosis of sarcoidosis between January 1, 1998, and March 31, 2015 (index date) were selected from a deidentified privately insured administrative claims database. Study patients must have at least 12 months of continuous health plan enrollment prior to the index date. High-cost patients were those in the top 20% of total health care costs during the 12 months following the index date (follow-up period), and the remaining patients were classified as lower-cost patients. Patient characteristics, comorbidities, health care resource use, and health care costs in the study period were compared between the high-cost and lower-cost patients. Multiple logistic regression was used to assess the relationship between patient characteristics and being a high-cost sarcoidosis patient. RESULTS: A total of 7,173 sarcoidosis patients met the selection criteria. The 20% of patients classified as high-cost patients accounted for approximately 72% of the total health care costs in the 12-month follow-up period. Compared with lower-cost patients, high-cost patients were slightly older (50.6 vs. 49.1 years) and had a higher comorbidity burden at baseline (Charlson Comorbidity Index = 1.8 vs. 0.7). Mean annual total health care cost for high-cost sarcoidosis patients was 10 times that of their lower-cost counterparts ($73,345 vs. $7,073). Mean annual health care cost was $119,878 for patients in the 95th-99th percentile and $375,436 for patients in the top 1% of spend. High-cost patients had greater medical resource use and costs across all places of service (i.e., inpatient, emergency department, outpatient, and other) compared with lower-cost patients. Findings showed that higher total health care cost resulted in a larger proportion of inpatient spend and a smaller proportion of outpatient and pharmacy spend. Adjusting for baseline characteristics, high-cost patients were associated with a number of factors with high ORs: the presence of comorbidities such as deficiency anemia (OR = 1.606; P < 0.001), depression (OR = 1.504; P < 0.001), or cardiac arrhythmia (OR = 1.493; P < 0.001); having an inpatient admission (OR = 9.771; P < 0.001); and use of biologic therapies adalimumab and/or infliximab (OR = 31.821; P < 0.001). CONCLUSIONS: This study described the characteristics of high-cost sarcoidosis patients and identified several high-cost indicators using contemporary administrative data. The health care cost distribution for sarcoidosis patients is highly skewed, making it a worthwhile endeavor to focus improvement efforts on patients in the top quintile. The study findings can help population health decision makers identify a subset of patients for targeted interventions aimed at improving quality of care and reducing overall costs.

PMID- 29172981 TI - Biosimilar Products in the Modern U.S. Health Care and Regulatory Landscape. AB - : Biosimilars have the potential to greatly reduce medication costs in the United States. As of July 1, 2017, 5 biosimilars have been approved by the FDA, but only 2 are available for purchase. This commentary outlines the efforts of an integrated health system to ensure biosimilar accessibility and discusses the current challenges and future implications. We highlight the implementation of a health plan policy and how a health system's formulary committee can encourage use while considering provider perceptions and operational challenges. In addition, we provide our perspective on potential implications for pricing, site of care, and pharmacy dispensing practices based on our experience with regulatory hurdles and market trends. Overall, we believe biosimilars are a good thing for the health care system, but their expected benefit may not be realized for years to come. DISCLOSURES: No outside funding supported this work.

AB - The recovery of high quality RNA from postmortem tissue is crucial to gene expression analyses. The acquisition of postmortem tissue has inherent time delays and, hence, understanding the temporal variation in the stability of total RNA is imperative. This experiment aimed: ( 1 ) to qualitatively and quantitatively assess the integrity of total RNA derived from a range of new-born ovine tissues (liver, spleen, thyroid, skeletal muscle, ileum, and perirenal adipose tissue) which were stored at ambient temperature until extraction at 0, 3, 6, and 9 h postmortem; and ( 2 ) to analyze the stability of the reference gene(s) and expression of specific target genes in these tissues. Postmortem sampling time resulted in variable reductions in the relative integrity number (RIN) values across the tissues, ranging from 0.9 to 1.8% in liver, spleen, skeletal muscle, and ileum to 5.7-11.1% in the thyroid and perirenal adipose tissues, respectively (P < 0.05). In conclusion, tissues with small reductions in RIN value can exhibit disproportionately large differences in the normalization factor used to calculate the target gene expression. Hence, changes in transcript abundance due to RNA degradation are not always sufficiently buffered through normalization with reference genes. The normalization factor should be presented alongside the RIN value in postmortem tissue studies. PMID- 29172983 TI - A Comparison of Brand and Biosimilar Granulocyte-Colony Stimulating Factors for Prophylaxis of Chemotherapy-Induced Febrile Neutropenia. AB - BACKGROUND: Filgrastim-sndz, a granulocyte-colony stimulating factor (G-CSF), was introduced as a biosimilar to filgrastim in 2015, but real-world comparative effectiveness for filgrastim versus filgrastim-sndz has not been reported to date. OBJECTIVES: To (a) compare the incidence of febrile neutropenia for patients taking filgrastim versus those taking filgrastim-sndz and (b) compare the incidence of a potential serious adverse event for filgrastim versus filgrastim-sndz. METHODS: This retrospective cohort study identified patients receiving a G-CSF following chemotherapy, using administrative claims from the Humana Research Database. Patients enrolled in a Medicare Advantage Prescription Drug plan with a claim for a G-CSF from October 1, 2015, through September 30, 2016, were identified. G-CSF use had to occur within 6 days of exposure to chemotherapy and without any subsequent chemotherapy within 14 days after G-CSF use. Febrile neutropenia requiring hospitalization was defined as hospitalization within 14 days after G-CSF use with (a) diagnosis of infection and/or neutropenia (broad definition) or (b) infection and neutropenia diagnoses (narrow definition). Serious adverse drug events (spleen rupture, acute respiratory syndrome, serious allergic reactions, capillary leak syndrome, thrombocytopenia, leukocytosis, cutaneous vasculitis, or bones and muscle ache) were also identified within 14 days after G-CSF use. An incidence difference of < 1% with 90% CI crossing zero qualified as support for noninferiority. Two-tailed chi square tests were also used to investigate differences. RESULTS: A total of 88 filgrastim and 101 filgrastim-sndz patients were identified. Filgrastim and filgrastim-sndz met the criteria for noninferiority based on an incidence difference of -0.6% (90% CI = -5.1%-4.0%; P = 0.84) for the broad definition of febrile neutropenia and a difference of -0.8% (90% CI = -3.8%-2.1%; P = 0.64) for the narrow definition. For the analysis of serious adverse events, an incidence difference of -2.5% (90% CI = -7.5%-2.5%; P = 0.42) for filgrastim compared with filgrastim-sndz was not sufficient to establish noninferiority. CONCLUSIONS: This study is one of the first analyses of real-world evidence regarding the noninferiority of filgrastim and filgrastim-sndz. The study results support noninferiority of filgrastim and filgrastim-sndz for prevention of febrile neutropenia requiring hospitalization. While noninferiority for serious adverse events was not supported, there was also no statistically significant difference between filgrastim and filgrastim-sndz. The study's small sample size could have limited the analysis of the relatively rare outcomes of febrile neutropenia requiring hospitalization and serious adverse events. A study including a larger numbers of patients taking filgrastim or filgrastim-sndz could provide additional insights. DISCLOSURES: This study received no outside funding.

PMID- 29172985 TI - Impact of desiccation and heat exposure stress on Salmonella tolerance to acidic conditions. AB - In a recent study, the pH of commonly used Salmonella pre-enrichment media became acidic (pH 4.0 to 5.0) when feed or feed ingredients were incubated for 24 h. Acidic conditions have been reported to injure or kill Salmonella. In this study, cultures of four known feed isolates (S. montevideo, S. senftenberg, S. tennessee, and S. schwarzengrund) and four important processing plant isolates (S. typhimurium, S. enteritidis, S. infantis, and S. heidelberg) were grown on meat and bone meal and later subjected to desiccation and heat exposure to stress the microorganism. The impact of stress on the isolates ability to survive in acidic conditions ranging from pH 4.0 to 7.0 was compared to the non-stressed isolate. Cell injury was determined on xylose lysine tergitol 4 (XLT4) and cell death determined on nutrient agar (NA). When measured by cell death in non stressed Salmonella, S. typhimurium was the most acid tolerant and S. heidelberg was the most acid sensitive whereas in stressed Salmonella, S. senftenberg was the most acid tolerant and S. tennessee was the most acid sensitive. The pH required to cause cell injury varied among isolates. With some isolates, the pH required for 50% cell death and 50% cell injury was similar. In other isolates, cell injury occurred at a more neutral pH. These findings suggest that the pH of pre-enrichment media may influence the recovery and bias the serotype of Salmonella recovered from feed during pre-enrichment. PMID- 29172986 TI - Bisphenol A and Bisphenol S release in milk under household conditions from baby bottles marketed in Italy. AB - A simple and sensitive validated analytical method based on liquid chromatography coupled to tandem fluorescence (FD) and ultraviolet (UV) spectrophotometry was applied to monitor the presence of bisphenol A and bisphenol S in plastic baby bottles marketed in Italy. The limits of detection (LOD) were 3.75 ng mL-1 and 80.00 ng mL-1, and those of quantification (LOQ) were 12.51 ng mL-1 and 260.00 ng mL-1 for BPA (FD detection) and for BPS (UV detection), respectively. BPA was found in only four samples, two samples undergone to microwave heating and two samples undergone to bottle warmer heating either at 40 degrees C or at 80 degrees C. Although the quantities of leached BPA were well below the reference dose for daily intake established by the European Food Safety Authority (EFSA) (4.0 ug kg-1 bw/day), the release of BPA and BPS from these plastic materials should be carefully considered by the government authorities to increase people's awareness on this issue and to protect the most vulnerable population group. PMID- 29172988 TI - The stratified win ratio. AB - The win ratio was first proposed in 2012 by Pocock and his colleagues to analyze a composite endpoint while considering the clinical importance order and the relative timing of its components. It has attracted considerable attention since then, in applications as well as methodology. It is not uncommon that some clinical trials require a stratified analysis. In this article, we propose a stratified win ratio statistic in a similar way as the Mantel-Haenszel stratified odds ratio, derive a general form of its variance estimator with a plug-in of existing or potentially new variance/covariance estimators of the number of wins for the two treatment groups, and assess its statistical performance using simulation studies. Our simulations show that our proposed Mantel-Haenszel-type stratified win ratio performs similarly to the Mantel-Haenszel stratified odds ratio for the simplified situation when the win ratio reduces to the odds ratio, and our proposed stratified win ratio is preferred compared to the inverse variance weighted win ratio and unweighted win ratio particularly when the data are sparse. We also formulate a homogeneity test following Cochran's approach that assesses whether the stratum-specific win ratios are homogeneous across strata, as this method is used frequently in meta-analyses and a better test for the win ratio homogeneity is not available yet. PMID- 29172987 TI - Claim MoreTM: Empowering African American Women to Make Healthy Choices. AB - Diabetes is a serious issue for African American women. The purpose of this project was to develop and test the feasibility of a culturally appropriate and faith-based healthy eating program for African American women at risk for developing diabetes. At total of 30 women from two churches completed a 12-week, faith-based program using a community-based approach with lay health educators in the church setting. Participants set healthy eating goals, attended weekly education classes, and received daily text messaging reminders related to their goals. Outcomes included high levels of social support, frequent engagement with the program, and improved healthy eating. This program demonstrated the ability to target African American women at risk for diabetes and engage them in a health related program. PMID- 29172989 TI - Association of Habitual Physical Activity With Cardiovascular Risk Factors and Target Organ Damage in Adolescents and Young Adults. AB - BACKGROUND: We aimed to (1) compare a subjective and objective measure of habitual physical activity (PA), (2) determine the association of PA and cardiovascular risk factors, and (3) test the hypothesis that PA is an independent determinant of target organ damage in youth. METHODS: Cross-sectional analysis of youth with and without type 2 diabetes [mean age = 22 (3.9) y]. PA was measured with International Physical Activity Questionnaire and Actical accelerometer. Target organ damage was assessed with echocardiography and peripheral arterial testing. Subjects were stratified into tertiles of total PA, and differences were tested by analysis of variance and chi2 tests. General linear models tested for independent associations. RESULTS: The correlation between International Physical Activity Questionnaire and accelerometry was weak (r = .23, P = .0003). Less active subjects had worse cardiovascular risk profiles and target organ damage, including stiffer arteries (P < .01). These outcome differences did not reach statistical significance when adjusted for covariates, such as lipid levels and glycemic control. CONCLUSION: Survey assessment of PA is complicated by inaccurate reporting. There is a strong association of habitual PA with cardiovascular risk factor clustering. PA may exert its beneficial effect on arterial stiffness in obese youth through improved glycemic control. PMID- 29172990 TI - Thresholds for infarction vary between gray matter and white matter in acute ischemic stroke: A CT perfusion study. AB - We aimed to investigate optimal perfusion thresholds defining ischemic core and penumbra for hemispheric-cortical gray matter (GM) and subcortical white matter (WM). A total of 65 sub-6 h ischemic stroke patients were assessed, who underwent acute computed tomography perfusion (CTP) and acute magnetic resonance imaging. CTP maps were generated by both standard singular value deconvolution (sSVD) and SVD with delay and dispersion correction (ddSVD). Analyses were undertaken to calculate sensitivity, specificity, and area under the curve (AUC) for each CTP threshold for core and penumbra in GM and WM. With sSVD, the core was best defined in GM by cerebral blood flow (CBF) < 30% (AUC: 0.73) and in WM by CBF < 20% (AUC: 0.67). With ddSVD, GM core was best defined by CBF < 35% (AUC: 0.75) and in WM by CBF < 25% (AUC: 0.68). A combined GM/WM threshold overestimated core compared to diffusion-weighted imaging, CBF < 25% from sSVD (1.88 ml, P = 0.007) and CBF < 30% from ddSVD (1.27 ml, P = 0.011). The perfusion lesion was best defined by Tmax > 5 s (AUC: 0.80) in GM and Tmax > 7 s (AUC: 0.75) in WM. With sSVD, a delay time (DT) > 3 s from ddSVD was the optimal for both GM (AUC: 0.78) and WM (AUC: 0.75). Using tissue-specific thresholds for GM/WM provides more accurate estimation of acute ischemic core. PMID- 29172991 TI - Characterisation of HRas local signal transduction networks using engineered site specific exchange factors. AB - Ras GTPases convey signals from different types of membranes. At these locations, different Ras isoforms, interactors and regulators generate different biochemical signals and biological outputs. The study of Ras localisation-specific signal transduction networks has been hampered by our inability to specifically activate each of these Ras pools. Here, we describe a new set of site-specific tethered exchange factors, engineered by fusing the RasGRF1 CDC25 domain to sub localisation-defining cues, whereby Ras pools at specific locations can be precisely activated. We show that the CDC25 domain has a high specificity for activating HRas but not NRas and KRas. This unexpected finding means that our constructs mainly activate endogenous HRas. Hence, their use enabled us to identify distinct pathways regulated by HRas in endomembranes and plasma membrane microdomains. Importantly, these new constructs unveil different patterns of HRas activity specified by their subcellular localisation. Overall, the targeted GEFs described herein constitute ideal tools for dissecting spatially-defined HRas biochemical and biological functions. PMID- 29172992 TI - Cellular immunogenicity of human papillomavirus vaccines Cervarix and Gardasil in adults with HIV infection. AB - Human papillomavirus (HPV) infection is a frequent cause of malignant and non malignant disease, in particular among persons with HIV. HPV serotype-specific anti L1 antibodies protect against HPV infection but little is known about prophylactic HPV vaccine-induced cell-mediated immunity against HPV in high-risk individuals. We recently showed that both HPV vaccines (Gardasil(r) and Cervarix(r)) induce solid, serological immune responses in HIV-infected persons. This study aimed to characterize HPV-specific CD4 T cells in HIV-infected HPV vaccine recipients, T cell responses being critical for B cell activation and antibody-isotype switching. Thirty HIV-infected patients on long-term antiretroviral treatment (ART) received 3 doses of either Cervarix (n = 15) or Gardasil (n = 15) vaccine at month 0, 1.5 and 6. Cryopreserved peripheral blood mononuclear cells (PBMC) from baseline, 7 and 12 months were subjected to 24-hour stimulation with specific pools of HPV L1-peptides (HPV6, 11, 16, 18, 31 and 45) and HPV E6/E7-peptide pools (HPV6/11 and HPV16/18). Fluorescence-activated cell sorting with intracellular staining (IC-FACS) against CD4, CD154, IL-2, and IFNgamma was performed. Frequencies (%) of HPV-antigen specific CD4+ T cells (CD154+/IL-2+ or CD154+/ IFNgamma+) were determined. Both HPV-vaccines significantly and comparably enhanced cell-mediated vaccine L1 antigen-specific immunity in HIV-positive adults receiving ART therapy at month 7 and 12 after first vaccine dose. This suggests that the vaccines induce CD4 T cellular memory despite HIV-induced immune compromisation. PMID- 29172993 TI - A Soup Service for Advanced Digestive Cancer Patients with Severe Anorexia in Palliative Care. AB - BACKGROUND/AIMS: The palliative care team (PCT), nutrition support team (NST), and department of nutrition in our hospital developed a special soup service for patients with terminal cancer. We evaluated the usefulness of this soup service for improving the mood in patients with advanced digestive cancer with severe anorexia. MATERIAL AND METHODS: We retrospectively reviewed the clinical data of 18 patients with advanced cancer originating in digestive organs who received soup service at our institution between 2015 and 2016. Members of the PCT, NST, and a licensed cook visited the bedside of each patient and served them a cup of soup twice a week. RESULTS: Fifteen patients (83%) were able to taste the soup with no adverse events, and 11 (73%) of them enjoyed the taste of the soup. In the five patients who died in our hospital during the service, the time between their last soup intake and death ranged from two to seven days (median three days). CONCLUSION: Even terminally ill patients suffering from advanced digestive cancer with severe anorexia were able to enjoy the taste of the soup served to them. The establishment of special meal service, such as this soup service, may not only relieve their stress but also support the strength of living and help improve their spiritual quality of life. PMID- 29172994 TI - Amiloride does not protect retinal nerve fibre layer thickness in optic neuritis in a phase 2 randomised controlled trial. AB - BACKGROUND: Recent basic and clinical evidence suggests amiloride may be neuroprotective in multiple sclerosis (MS) through the blockade of the acid sensing ion channel (ASIC). OBJECTIVE: To examine the neuroprotective efficacy of amiloride in acute optic neuritis (ON). METHODS: A total of 48 patients were recruited to a phase 2, double blind, single site, randomised controlled trial. Scanning laser polarimetry (GDx) at 6 months was the primary outcome measure and optical coherence tomography (OCT) and visual and electrophysiological measures were secondary outcome measures. Participants aged 18-55 years, <=28 days of onset of first episode unilateral ON, were randomised to amiloride (10 mg daily for 5 months) or placebo ( clinicaltrials.gov , NCT 01802489). RESULTS: Intention to-treat (ITT) cohort consisted of 43 patients; 23 placebo and 20 amiloride. No significant drug-related adverse events occurred. No significant differences were found in GDx ( p = 0.840). Visual evoked potentials (VEP) were significantly prolonged in the amiloride group compared to placebo ( p = 0.004). All other secondary outcome measures showed no significant difference. Baseline analysis of OCT data demonstrated a significant pre-randomisation thinning of ganglion cell layer. CONCLUSION: Amiloride has not demonstrated any neuroprotective benefit within this trial paradigm, but future neuroprotective trials in ON should target the window of opportunity to maximise potential neuroprotective benefit.

Until recently, no durable treatment options were available for patients with advanced disease. As an immunogenic cancer, MCC was hypothesized to be a candidate for PD-L1/PD-1 targeted therapy. On March 23, 2017 the US Food and Drug Administration granted accelerated approval for avelumab, an anti-PD-L1 monoclonal antibody, for the treatment of metastatic MCC on the basis of the JAVELIN Merkel 200 trial. Here we examine the results and implications of this pivotal study, published in Lancet Oncology by Kaufman et al., as well as current developments in the use of immune-checkpoint therapies for treating patients with MCC.

AB - The combination of two binary diagnostic tests in order to increase the accuracy of the diagnosis of a disease is a frequent procedure in clinical practice. When considering the losses associated with an erroneous classification with a binary diagnostic test, the parameter that is used to assess the diagnostic test is the weighted kappa coefficient. The weighted kappa coefficient depends on the sensitivity and the specificity of the diagnostic test, on the disease prevalence and on the weighting index. In this article, we study the combination of the weighted kappa coefficients of two binary diagnostic tests, defining the parameters and studying the conditions under which the combination of the two diagnostic tests increases the value of the weighted kappa coefficient of the combination. The Fieller method has been applied to obtain a confidence interval for the ratio between the combined weighted kappa coefficient and the weighted kappa coefficient of each diagnostic test. A program in R has been written to solve the problem studied and it is available as complementary material. The results have been applied to a real example. PMID- 29172998 TI - Establishment of H2Mab-119, an Anti-Human Epidermal Growth Factor Receptor 2 Monoclonal Antibody, Against Pancreatic Cancer. AB - Human epidermal growth factor receptor 2 (HER2) is overexpressed in breast cancer and is associated with poor clinical outcomes. In addition, HER2 expression has been reported in other cancers, such as gastric, colorectal, lung, and pancreatic cancers. An anti-HER2 humanized antibody, trastuzumab, leads to significant survival benefits in patients with HER2-overexpressing breast cancers and gastric cancers. Herein, we established a novel anti-HER2 monoclonal antibody (mAb), H2Mab-119 (IgG1, kappa), and characterized its efficacy against pancreatic cancers using flow cytometry, Western blot, and immunohistochemical analyses. H2Mab-119 reacted with pancreatic cancer cell lines, such as KLM-1, Capan-2, and MIA PaCa-2, but did not react with PANC-1 in flow cytometry analysis. Western blot analysis also revealed a moderate signal for KLM-1 and a weak signal for MIA PaCa-2, although H2Mab-119 reacted strongly with LN229/HER2 cells. Finally, immunohistochemical analyses with H2Mab-119 revealed sensitive and specific reactions against breast and colon cancers but did not react with pancreatic cancers, indicating that H2Mab-119 is useful for detecting HER2 overexpression in pancreatic cancers using flow cytometry and Western blot analyses. PMID- 29172997 TI - Identification of ANXA2 (annexin A2) as a specific bleomycin target to induce pulmonary fibrosis by impeding TFEB-mediated autophagic flux. AB - Bleomycin is a clinically potent anticancer drug used for the treatment of germ cell tumors, lymphomas and squamous-cell carcinomas. Unfortunately, the therapeutic efficacy of bleomycin is severely hampered by the development of pulmonary fibrosis. However, the mechanisms underlying bleomycin-induced pulmonary fibrosis, particularly the molecular target of bleomycin, remains unknown. Here, using a chemical proteomics approach, we identify ANXA2 (annexin A2) as a direct binding target of bleomycin. The interaction of bleomycin with ANXA2 was corroborated both in vitro and in vivo. Genetic depletion of anxa2 in mice mitigates bleomycin-induced pulmonary fibrosis. We further demonstrate that Glu139 (E139) of ANXA2 is required for bleomycin binding in lung epithelial cells. A CRISPR-Cas9-engineered ANXA2E139A mutation in lung epithelial cells ablates bleomycin binding and activates TFEB (transcription factor EB), a master regulator of macroautophagy/autophagy, resulting in substantial acceleration of autophagic flux. Pharmacological activation of TFEB elevates bleomycin-initiated autophagic flux, inhibits apoptosis and proliferation of epithelial cells, and ameliorates pulmonary fibrosis in bleomycin-treated mice. Notably, we observe lowered TFEB and LC3B levels in human pulmonary fibrosis tissues compared to normal controls, suggesting a critical role of TFEB-mediated autophagy in pulmonary fibrosis. Collectively, our data demonstrate that ANXA2 is a specific bleomycin target, and bleomycin binding with ANXA2 impedes TFEB-induced autophagic flux, leading to induction of pulmonary fibrosis. Our findings provide insight into the mechanisms of bleomycin-induced fibrosis and may facilitate development of optimized bleomycin therapeutics devoid of lung toxicity.

AB - INTRODUCTION: Profoundly impaired left ventricular (LV) function in patients undergoing femoral veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) can result in intra-cardiac stasis and thrombus formation. There have been several attempts to improve LV unloading in patients with peripheral VA-ECMO, either by improving contractility or by venting the LV. METHODS: Data from all patients who underwent femoral VA-ECMO between 2007 and 2015 due to cardiogenic decompensation were retrospectively analysed regarding intra-cardiac thrombus formation. RESULTS: In total, 11 of 281 patients (3.91%) with femoral VA-ECMO developed an intra- or extra-cardiac thrombus despite adequate anticoagulation therapy. None of the patients survived this serious complication. CONCLUSION: Management strategies for patients with femoral VA-ECMO support and severely impaired LV function must be reassessed to avoid insufficient LV unloading at an early stage of ECMO therapy. Early LV decompression should be considered in patients with insufficient unloading of the LV to prevent intra-cardiac thrombus formation. PMID- 29173000 TI - The central dogma, "GMO" and defective epistemology. AB - The expression "Genetically Modified Organisms" was coined to indicate a group of agricultural products (mostly crops and vegetables), modified through direct DNA recombination in order to obtain useful phenotypic traits or to inhibit undesirable characteristics. But the border between rDNA ("GMO") and other biotech methods is blurred. Moreover, the ill-assorted group is frequently charged with having peculiar, negative characteristics: many activists, part of the public and a few social science scholars think that "GMOs" are all dubious, even inherently dangerous. However, theoretical justifications of this alleged problematic nature which is supposed to be necessarily linked to the "splicing" of DNA, only when applied to agricultural products, are missing: the only text which tries to go in depth on the subject, an article by biologist Barry Commoner, takes aim at the wrong target, misunderstanding the Central Dogma. "GMO" is a term that has no clear reference, let alone in a detrimental sense. The only attempt to give it epistemological dignity fails. PMID- 29173001 TI - Validating a research ethnicity questionnaire using genomic markers. AB - AIM: Population stratification is a confounding factor in genetic association studies. Self-report measures, the most common method of collecting ethnicity, may be less reliable for psychiatric patients. This study aims to validate our research ethnicity questionnaire as a reliable measure of genetic ancestry. METHODS: The validity of our questionnaire was compared with genetic ancestry according to structured association tests and dimensional reduction methods. Our research tool was also compared with a standard multiple choice questionnaire. RESULTS: Our research questionnaire was highly consistent with genetic ancestry. The standard questionnaire demonstrated a greater degree of inconsistency in identifying ethnicity. CONCLUSION: Collecting information on the geographical ancestry of each individual's grandparents provides a more comprehensive view of ethnicity to prevent population stratification and wasted finances on genotyping. PMID- 29173002 TI - miR-509-3p promotes cisplatin-induced apoptosis in ovarian cancer cells through the regulation of anti-apoptotic genes. AB - AIM: Previous observations have implicated miR-509-3p's ability in regulating cisplatin-triggered apoptosis in ovarian cancer. However, the underlying mechanisms were not fully understood. MATERIALS & METHODS: The roles of miR-509 3p in cellular apoptosis were assessed through MTT and DAPI assays. The confirmation of the regulation of BCL2 family members by miR-509-3p was investigated by luciferase reporter assay, western blot, quantitative real-time PCR and rescue experiments. RESULTS: MiR-509-3p can decrease the IC50 values of cisplatin and promote apoptosis in ovarian cancer cells. Furthermore, on a panel of anti-apoptotic proteins, we identified that miR-509-3p could regulate BCL2, BCL2L2 and MCL1 via their 3'UTRs. CONCLUSION: Our study demonstrates that miR-509 3p could sensitize ovarian cancer cells to cisplatin treatment by targeting multiple anti-apoptosis genes including BCL2. PMID- 29173003 TI - Life-threatening idiopathic reaction to hydrochlorothiazide treated with veno venous extracorporeal membrane oxygenation. AB - Hydrochlorothiazide has been shown to cause rare, but serious non-cardiogenic pulmonary edema. We present a case report of a patient with apparent septic shock and acute respiratory distress syndrome (ARDS) requiring life-sustaining veno venous extracorporeal membrane oxygenation (VV-ECMO). Upon further review of the literature and the chronology of the patient's presentation, her condition was most likely due to an immune-mediated reaction to hydrochlorothiazide. This represents the first case, to our knowledge, of such a severe reaction to hydrochlorothiazide supported with ECMO therapy. PMID- 29173004 TI - Advancing cancer drug development through precision medicine and innovative designs. AB - Precision medicine has been a hot topic in drug development over the last decade. Biomarkers have been proven useful for understanding the disease progression and treatment response in precision medicine development. Advancement of high throughput omics technologies has enabled fast identification of molecular biomarkers with low cost. Although biomarkers have brought many promises to drug development, steep challenges arise due to a large amount of data, complexity of technology, and lack of full understanding of biology. In this article, we discuss the technologies and statistical issues that are related to omics biomarker discovery. We also provide an overview of the current development of biomarker-enabled cancer clinical trial designs. PMID- 29173005 TI - Pharmacogenetics and psoriasis: is targeted treatment a possibility? PMID- 29173007 TI - Predictors and outcome of systemic lupus erythematosus (SLE) admission rates in a large teaching hospital in sub-Saharan Africa. AB - Although it was previously believed that systemic lupus erythematosus was uncommon among Africans, it has become increasingly apparent that the incidence is higher, and socioeconomic challenges such as physician shortages, poor medical facility access, and poor health literacy may worsen prognosis. This retrospective study examines characteristics and outcomes of hospitalized systemic lupus erythematosus patients over a two-year period and serves as a baseline for comparison for future studies to examine the outcomes with the provision of more dedicated care. There were 51 patient admissions over a two year period, with a mean duration from start of illness to admission of approximately two years. Duration of admission ranged from one to 140 days with a mean period of 26.12 days (SD +/- 26.6). There were 22 deaths (43.1% of admissions), which were mainly due to infections and renal complications. Factors associated with risk of death in regression analysis were: infections, fever, disease flare, musculoskeletal involvement, amenorrhea, depression, a clinical finding of hepatomegaly, and chest infection. Understanding the effect and outcome of systemic lupus erythematosus across different countries can elucidate the role of genetic, environmental, and other causative factors in the progression of the disease. PMID- 29173006 TI - Systematic analysis of ATG13 domain requirements for autophagy induction. AB - Macroautophagy/autophagy is an evolutionarily conserved cellular process whose induction is regulated by the ULK1 protein kinase complex. The subunit ATG13 functions as an adaptor protein by recruiting ULK1, RB1CC1 and ATG101 to a core ULK1 complex. Furthermore, ATG13 directly binds both phospholipids and members of the Atg8 family. The central involvement of ATG13 in complex formation makes it an attractive target for autophagy regulation. Here, we analyzed known interactions of ATG13 with proteins and lipids for their potential modulation of ULK1 complex formation and autophagy induction. Targeting the ATG101-ATG13 interaction showed the strongest autophagy-inhibitory effect, whereas the inhibition of binding to ULK1 or RB1CC1 had only minor effects, emphasizing that mutations interfering with ULK1 complex assembly do not necessarily result in a blockade of autophagy. Furthermore, inhibition of ATG13 binding to phospholipids or Atg8 proteins had only mild effects on autophagy. Generally, the observed phenotypes were more severe when autophagy was induced by MTORC1/2 inhibition compared to amino acid starvation. Collectively, these data establish the interaction between ATG13 and ATG101 as a promising target in disease-settings where the inhibition of autophagy is desired. PMID- 29173009 TI - Imaging patterns of gray and white matter abnormalities associated with PASAT and SDMT performance in relapsing-remitting multiple sclerosis. AB - OBJECTIVES: To map the regional patterns of white matter (WM) microstructural abnormalities and gray matter (GM) atrophy exclusively associated with reduced performance in the Symbol Digit Modalities Test (SDMT) and Paced Auditory Serial Addition Test (PASAT) in relapsing-remitting (RR) multiple sclerosis (MS) patients. METHODS: In all, 177 RRMS patients and 80 healthy controls (HC) were studied. WM microstructural abnormalities were investigated on diffusion tensor images using tract-based spatial statistics analysis, and regional GM atrophy was estimated on three-dimensional (3D) T1-weighted images using voxel-based morphometry. RESULTS: Compared to HC, RRMS patients showed the expected pattern of cortical-subcortical GM atrophy and WM microstructural abnormalities. In patients, diffusivity abnormalities of supratentorial WM tracts correlated with both SDMT and PASAT scores. Lower SDMT performance was also associated with WM damage in several infratentorial WM tracts. Lower SDMT scores correlated with atrophy of the right anterior cingulate cortex, left postcentral gyrus, and right middle temporal gyrus, whereas lower PASAT scores correlated with atrophy of the deep GM nuclei, bilaterally, and several fronto-temporo-occipital regions. CONCLUSION: In RRMS patients, regional damage of different neural systems helps explaining reduced performance in SDMT and PASAT. WM microstructural damage typified reduced SDMT performance, whereas atrophy of several GM regions distinguished reduced PASAT performance. PMID- 29173008 TI - Monocyte-mediated chemotherapy drug delivery in glioblastoma. AB - AIM: To mechanistically prove the concept of monocyte-mediated nano drug delivery in glioblastoma (GBM). RESULTS: nano-doxorubicin-loaded monocytes (Nano-DOX-MC) were viable, able to cross an artificial endothelial barrier and capable of infiltrating GBM spheroids and releasing drug therein. GBM cells stimulated unloading of Nano-DOX-MC and took up the unloaded drug and released damage associated molecular patterns. In mice with orthotopic GBM xenografts, Nano-DOX MC resulted in much improved tumor drug delivery efficacy and damage-associated molecular patterns emission. Mechanistically, Nano-DOX was found sequestered in the lysosomal compartment and to induce autophagy, which may underlie MC's tolerance to Nano-DOX. Lysosomal exocytosis was found involved in the discharging mechanism of intracellular Nano-DOX. CONCLUSION: Nano-DOX can be effectively delivered by MC in GBM and induce cancer cell damage. PMID- 29173010 TI - Spiritual Well-Being, Depression, and Stress Among Hemodialysis Patients in Jordan. AB - PURPOSE: The spiritual dimension of a patient's life is an important factor that may mediate detrimental impacts on mental health. The lack of research investigating spiritual well-being, religiosity, and mental health among Jordanian hemodialysis patients encouraged this research. This study explored levels of spiritual well-being and its associations with depression, anxiety, and stress. DESIGN: A quantitative, cross-sectional correlational study. METHOD: A sample of 218 Jordanian Muslim hemodialysis patients completed a structured, self administered questionnaire. The data were analyzed using descriptive statistics and linear multivariate regression models. FINDINGS: The hemodialysis patients had, on average, relatively low levels of spiritual well-being, moderate depression, severe anxiety, and mild to moderate stress. The results of the regression models indicated that aspects of spiritual well-being were negatively associated with depression, anxiety, and stress, but only existential well-being consistently retained significant associations after controlling for religious well-being, religiosity, and sociodemographic variables. CONCLUSIONS: Greater spiritual and existential well-being of Jordanian hemodialysis patients were significantly associated with less depression, anxiety, and stress. It appears that these patients use religious and spiritual beliefs and practices as coping mechanisms to overcome their depression, anxiety, and stress. The implications for holistic clinical practice are explored. PMID- 29173011 TI - Genetic deletion of the Rho GEF Net1 impairs mouse macrophage motility and actin cytoskeletal organization. AB - Macrophages are innate immune cells that constantly patrol an organism to fulfill protective and homeostatic roles. Previous studies have shown that Rho GTPase activity is required for macrophage mobility, yet the roles of upstream regulatory proteins controlling Rho GTPase function in these cells are not well defined. Previously we have shown that the RhoA GEF Net1 is required for human breast cancer cell motility and extracellular matrix invasion. To assess the role of Net1 in macrophage motility, we isolated bone marrow macrophage (BMM) precursors from wild type and Net1 knockout mice. Loss of Net1 did not affect the ability of BMM precursors to differentiate into mature macrophages in vitro, as measured by CD68 and F4/80 staining. However, Net1 deletion significantly reduced RhoA activation, F-actin accumulation, adhesion, and motility in these cells. Nevertheless, similar to RhoA/RhoB double knockout macrophages, Net1 deletion did not impair macrophage recruitment to the peritoneum in a mouse model of sterile inflammation. These data demonstrate that Net1 is an important regulator of RhoA signaling and motility in mouse macrophages in vitro, but that its function may be dispensable for macrophage recruitment to inflammatory sites in vivo. PMID- 29173013 TI - Temporal compression in episodic memory for real-life events. AB - Remembering an event typically takes less time than experiencing it, suggesting that episodic memory represents past experience in a temporally compressed way. Little is known, however, about how the continuous flow of real-life events is summarised in memory. Here we investigated the nature and determinants of temporal compression by directly comparing memory contents with the objective timing of events as measured by a wearable camera. We found that episodic memories consist of a succession of moments of prior experience that represent events with varying compression rates, such that the density of retrieved information is modulated by goal processing and perceptual changes. Furthermore, the results showed that temporal compression rates remain relatively stable over one week and increase after a one-month delay, particularly for goal-related events. These data shed new light on temporal compression in episodic memory and suggest that compression rates are adaptively modulated to maintain current goal relevant information. PMID- 29173012 TI - Interleukin-6 Affects Aging-Related Changes of the PPARalpha-PGC-1alpha Axis in the Myocardium. AB - Aging is related to gradual increase of interleukin 6 (IL-6) plasma level that affects peroxisome proliferator-activated receptor (PPAR) expression. We evaluated age-related changes in cardiac expression of PPARalpha, its coactivator PGC-1alpha, and selected downstream proteins in mice with systemic IL-6 knockout (IL6KO). Male C57BL6/J wild-type (WT) and IL6KO mice were used at the age of 16 20 weeks (young) and 24-30 months (senescent). Echocardiography and electron microscopy were applied to assess the function and ultrastructure of the heart. Western blotting and quantitative real-time PCR were used to estimate protein and mRNA levels of selected genes. PPARalpha expression in the myocardium of young IL6KO animals is lower and remains unchanged with aging, whereas in WT mice it declines with age and in both senescent groups it is equal. We observed aging related upregulation of PGC-1alpha and less pronounced decline of Sirt3 in IL6KO animals; the level of cytochrome C was significantly decreased in IL6KO group only, suggesting disturbed mitochondrial function, which was not sufficient to evoke obvious changes in cardiac performance and function assessed by echocardiography. IL-6 and aging are involved in regulation of PPARalpha and PGC 1alpha expression and may influence the mitochondrial function. PMID- 29173014 TI - Initiation and completion rates of inactivated hepatitis A vaccination among children born between 2005 and 2014 in Zhejiang province, east China. AB - OBJECTIVES: To evaluate the initiation and completion and timeliness of inactivated hepatitis A vaccine (HAV-I) series, to identify the missed opportunities for HAV-I series, and to examine determinants associated with the completion of HAV-I. METHODS: Children born from 1 January 2005 to 31 December 2014 and registered in Zhejiang provincial immunization information system (ZJIIS), were enrolled in this study. Descriptive statistics were used to describe the initiation and completion, the timeliness and the missed opportunities for HAV-I. Logistic regression analysis was applied to explore the determinants of the completeness of HAV-I. RESULTS: The initiation rate of HAV-I increased from 8.1% for the 2005 birth cohort to 13.2% for the 2014 birth cohort. The completion rate of HAV-I increased from 4.2% for the 2005 birth cohort to 7.8% for the 2014 birth cohort. The timeliness rate of the 1st dose of HAV-I increased from 38.2% for the 2005 birth cohort to 57.9% for the 2014 birth cohort. The timeliness rate the 2nd dose of HAV-I increased from 17.3% for the 2005 birth cohort to 35.3% for the 2014 birth cohort. 78.3% of the children who did not initiated any hepatitis A vaccine, had at least one immunization clinic visit after their 18th month of age. 36.0% of the children who received the 1st dose of HAV-I but did not receive the 2nd dose, had at least one immunization clinic visit after 6 months from the date of receiving the 1st dose of HAV-I. The determinants including year of birth, socio-economic development level of municipals, place of delivery, receipt of MMR/VarV were associated with the completion of HAV-I series. CONCLUSION: Although the initiation and completion of HAV-I series had improved in recent years, these indicators were still lower than those for other vaccines scheduled at the similar age. It is important for providers to identify every opportunity for HAV-I vaccination and to assure that children get protection from this vaccine-preventable disease. PMID- 29173015 TI - When Patients Tell Their Own Stories: A Meta-Narrative Study of Web-Based Personalized Texts of 214 Melanoma Patients' Journeys in Four Countries. AB - Malignant melanoma is an aggressive, recalcitrant disease. Its impact on people can be compounded by the physical and psychosocial consequences of medical management. Providing melanoma patients with patient-centered care that is effective, safe, and supportive throughout their journey requires knowledge of patients' progressive experiences and evolving perspectives. With ethical approval, we undertook a meta-narrative study of 214 experiential accounts of melanoma collected from the personal story sections of melanoma and cancer support websites. Using a narrative approach, we qualitatively examined the care experiences represented in these accounts and identified needs for supportive care in a framework reflective of the personal patient journey. We differentiate these across three key periods: lead-up to diagnosis; diagnosis, treatment, and recovery; and posttreatment and recurrence, and provide a visual representation of the patient journey. This article contributes to the growing body of work that utilizes Internet content as sources of qualitative, experiential health care data. PMID- 29173016 TI - Fast, asymmetric and nonhomogeneous clearance of SiC nanoaerosol assessed by micro-particle-induced x-ray emission. AB - AIM: To study the biopersistence of a silicon carbide (SiC) nanoaerosol in rat lungs, as time-dependent clearance and spatial distribution. MATERIALS & METHODS: Sprague-Dawley rats were exposed 6 h/day during 5 days to a SiC nanoaerosol at 4.91 mg SiC/l. SiC biopersistence in rat lungs sections was assessed over 28 days by micro-particle-induced x-ray emission (MUPIXE) as 2D maps and by particle induced x-ray emission (PIXE) for whole-lung quantification. 2D maps were analyzed for SiC spatial distribution as skewness and kurtosis. RESULTS: Half time clearance was 10.9 +/- 0.9 days, agreeing with PIXE measurements. Spatial temporal analysis of SiC indicated decreased symmetry and homogeneity. CONCLUSION: Fast SiC clearance points that current nanoaerosol exposure may not be enough to trigger lung overload. Spatial distribution shows an asymmetric and nonhomogeneous SiC clearance. PMID- 29173017 TI - MYC leads the way. AB - Members of the MYC family of proto-oncogenes are the most commonly deregulated genes in all human cancers. MYC proteins drive an increase in cellular proliferation and facilitate multiple aspects of tumor initiation and progression, thereby controlling all hallmarks of cancer. MYC's ability to drive metabolic reprogramming of tumor cells leading to biomass accumulation and cellular proliferation is the most studied function of these oncogenes. MYC also regulates tumor progression and is often implicated in resistance to chemotherapy and in metastasis. While most oncogenic functions of MYC are attributed to its role as a transcription factor, more recently, new roles of MYC as a pro-survival factor in the cytoplasm suggest a previously unappreciated diversity in MYC's roles in cancer progression. This review will focus on the role of MYC in invasion and will discuss the canonical functions of MYC in Epithelial to Mesenchymal Transition and the cytoplasmic functions of MYC-nick in collective migration.

PMID- 29173022 TI - Parametric modeling and optimal experimental designs for estimating isobolograms for drug interactions in toxicology. AB - In toxicology and related areas, interaction effects between two substances are commonly expressed through a combination index [Formula: see text] evaluated separately at different effect levels and mixture ratios. Often, these indices are combined into a graphical representation, the isobologram. Instead of estimating the combination indices at the experimental mixture ratios only, we propose a simple parametric model for estimating the underlying interaction function. We integrate this approach into a joint model where both the parameters of the dose-response functions of the singular substances and the interaction parameters can be estimated simultaneously. As an additional benefit, this concept allows to determine optimal statistical designs for combination studies optimizing the estimation of the interaction function as a whole. From an optimal design perspective, finding the interaction parameters generally corresponds to a [Formula: see text]-optimality resp. [Formula: see text]-optimality design problem, while estimation of all underlying dose response parameters corresponds to a [Formula: see text]-optimality design problem. We show how optimal designs can be obtained in either case as well as how combination designs providing reasonable performance in regard to both criteria can be determined by putting a constraint on the efficiency in regard to one of the criteria and optimizing for the other. As all designs require prior information about model parameter values, which may be unreliable in practice, the effect of misspecifications is investigated as well. PMID- 29173023 TI - Erratum. PMID- 29173018 TI - Formation of pollen apertures in Arabidopsis requires an interplay between male meiosis, development of INP1-decorated plasma membrane domains, and the callose wall. AB - In most plant species, surfaces of pollen grains display characteristic patterns of apertures, formed by the gaps in the pollen wall exine. The aperture patterns are species-specific and tend to be very precise, with pollen of each species usually developing a certain number of apertures placed at distinct positions and acquiring specific morphology. The precision with which pollen apertures are produced suggests that developing pollen grains possess robust mechanisms that allow them to specify particular membrane domains as the future-aperture sites and to protect these sites from exine deposition. Recently, we demonstrated that formation of apertures in Arabidopsis depends on certain membrane domains attracting a novel protein, INP1, that assembles into punctate lines and helps to anchor these membrane domains to the overlying callose wall. Here we show that in the absence of male meiosis the ability of INP1 to assemble into lines at the pollen surface is compromised. However, INP1 still arrives to the pollen surface and mediates the interactions between the plasma membrane and the callose wall, potentially contributing to the formation of grossly abnormal patterns on pollen surface. PMID- 29173025 TI - Functional nanocarrier for drug and gene delivery via local administration in mucosal tissues. AB - Local administration has many advantages for treating diseases. However, the surface mucus layer becomes a major obstacle that easily traps and fast removes local administrated drugs and genes in mucosal tissues. Fortunately, the rapidly developing nanocarriers with special physical and chemical properties may help to refine the treatment of mucosal tissues via delivering drugs and genes to the target tissue, and prolong the drug action time. Therefore, this review focuses on the strategies to apply different nanocarriers for drug-delivery in mucosal tissues, including mucoadhesive and mucus-penetrating types. Delivering drugs and genes to anatomical sites with high mucus turnover becomes more feasible and effective, and maintains sufficient local drug concentration to improve treatment efficacy. PMID- 29173026 TI - Consistency ensured test strategies for supportive evidence of treatment efficacy in noninferiority clinical trials. AB - Noninferiority (NI) clinical trials are designed to demonstrate that a new treatment is not unacceptably worse than an active control on a clinically meaningful endpoint. While such an endpoint can be of any type, the focus of this manuscript is on the binary-type endpoint. Examples of this endpoint can be clinical cure endpoint for patients with bacterial diseases or based on a pre specified virological threshold for viral diseases. However, in addition to assessing such a binary endpoint for the NI comparison, the trial may also evaluate a second clinically relevant endpoint for providing additional support to the evidence of the designated primary endpoint. Specifically, if the trial is successful in demonstrating statistical significance on the first endpoint, then observing at least a positive trend in efficacy on the second endpoint may provide additional supportive evidence of efficacy. The second endpoint can be a time-to-event type endpoint, such as time-to-symptom resolution (TSR) or time to all-cause mortality for infectious disease trials, time-to-wound closure for wound healing trials, or other endpoints. We propose two consistency ensured test strategies for the two hypotheses of a trial, one associated with the binary endpoint and the other with the second endpoint, both with the objective of drawing inference regarding the efficacy of the new treatment based on findings from testing the two hypotheses. A key feature of these test strategies is that basically it does not require multiplicity adjustment of the significance levels. We conclude with general discussion of the testing methods and possible applications to unmet medical need trials. PMID- 29173024 TI - Main components of pomegranate, ellagic acid and luteolin, inhibit metastasis of ovarian cancer by down-regulating MMP2 and MMP9. AB - Ovarian cancer is the third most common cancer in the female reproductive organs and epithelial ovarian cancer has the highest lethality of all gynecological cancers. Pomegranate fruit juice (PFJ) has been shown to inhibit the growth of several types of cancer other than ovarian cancer. In this study, we exposed the ovarian cancer cell line A2780 to PFJ and two of its components (ellagic acid and luteolin). MTT and wound healing assays demonstrated that all three treatments suppressed the proliferation and migration of the ovarian cancer cells. In addition, western blotting and ELISA assays showed that the expression levels of MMP2 and MMP9 gradually decreased after treatment with increasing concentrations of ellagic acid and luteolin. To confirm our findings in the in vitro experiments, we used another ovarian cancer cell line, ES-2, in nude mice experiments. All three treatments inhibited tumor growth without obvious side effects. Furthermore, compared with the control group, the expression levels of MMP2 and MMP9 were depressed. Ellagic acid induced a greater effect than luteolin, suggesting that ellagic acid might be a promising candidate for further preclinical testing for treatment of human ovarian cancer. PMID- 29173027 TI - Cross-cultural differences in item and background memory: examining the influence of emotional intensity and scene congruency. AB - After viewing a scene, individuals differ in what they prioritise and remember. Culture may be one factor that influences scene memory, as Westerners have been shown to be more item-focused than Easterners (see Masuda, T., & Nisbett, R. E. (2001). Attending holistically versus analytically: Comparing the context sensitivity of Japanese and Americans. Journal of Personality and Social Psychology, 81, 922-934). However, cultures may differ in their sensitivity to scene incongruences and emotion processing, which may account for cross-cultural differences in scene memory. The current study uses hierarchical linear modeling (HLM) to examine scene memory while controlling for scene congruency and the perceived emotional intensity of the images. American and East Asian participants encoded pictures that included a positive, negative, or neutral item placed on a neutral background. After a 20-min delay, participants were shown the item and background separately along with similar and new items and backgrounds to assess memory specificity. Results indicated that even when congruency and emotional intensity were controlled, there was evidence that Americans had better item memory than East Asians. Incongruent scenes were better remembered than congruent scenes. However, this effect did not differ by culture. This suggests that Americans' item focus may result in memory changes that are robust despite variations in scene congruency and perceived emotion. PMID- 29173028 TI - Easy Debonding of Ceramic Brackets Bonded with a Light-Cured Orthodontic Adhesive Containing Microcapsules with a CO2 Laser. AB - OBJECTIVE: An easy debonding method for ceramic brackets using a light-cured Bis GMA resin containing heat-expandable microcapsules and CO2 laser was investigated. BACKGROUND: Ceramic brackets are used frequently in orthodontic treatment because of their desirable esthetic properties. However, the application of heavy force to ceramic brackets in debonding can fracture the tooth enamel and ceramic brackets, causing tooth pain. MATERIALS AND METHODS: In total, 60 freshly extracted bovine permanent mandibular incisors were divided randomly into 10 groups of 6 specimens each, corresponding to the number of variables tested. Ceramic brackets were bonded to bovine permanent mandibular incisors using an orthodontic bonding agent containing heat-expandable microcapsules at different levels (0-30 wt%) and resin composite paste, and cured by a curing device. The bond strengths were measured before and after CO2 laser irradiation, and the temperature increase in the pulp chamber in fresh human first premolars was also evaluated. RESULTS: With CO2 laser irradiation for 5 sec to the bracket, the bond strength in the 25% microcapsule group decreased significantly, to ~0.17-fold, compared with that of the no-laser group (p < 0.05). The maximum temperature increase in the pulp chamber was 5.3 degrees C with laser irradiation, which was less than the level that induces pulp damage. CONCLUSIONS: From these results, it seems likely that the combined use of a light cured orthodontic bonding agent containing microcapsules and a CO2 laser is a simple debonding system for ceramic brackets, with less debonding time and enamel damage. PMID- 29173029 TI - Enzymatically synthesized megalo-type isomaltosaccharides enhance the barrier function of the tight junction in the intestinal epithelium. AB - Megalo-type isomaltosaccharides are an enzymatically synthesized foodstuff produced by transglucosylation from maltodextrin, and they contain a mid-chain length polymer of D-glucose with alpha-1,6-glycoside linkages. The injection of a solution of megalo-type isomaltosaccharides (1-4%(w/v), average DP = 12.6), but not oligo-type isomaltosaccharides (average DP = 3.3), into the intestinal lumen dose-dependently reduced the transport rates of tight junction permeable markers in a ligated loop of the anesthetized rat jejunum. Application of the megalosaccharide also suppressed the transport of tight junction markers and enhanced transepithelial electrical resistance (TEER) in Caco-2 cell monolayers. Cholesterol sequestration by methyl-beta-cyclodextrin in the Caco-2 monolayers abolished the effect of megalosaccharide. Treatment with anti-caveolin-1 and a caveolae inhibitor, but not clathrin-dependent endocytosis and macropinocytosis inhibitors, suppressed the increase in TEER. These results indicate that isomaltosaccharides promote the barrier function of tight junctions in the intestinal epithelium in a chain-length dependent manner and that caveolae play a role in the effect. PMID- 29173030 TI - A Summary of Pediatric Palliative Care Team Structure and Services as Reported by Centers Caring for Children with Cancer. AB - BACKGROUND: Little is known about the composition, availability, integration, communication, perceived barriers, and work load of pediatric palliative care (PPC) providers serving children and adolescents with cancer. OBJECTIVE: To summarize the structure and services of programs to better understand successes and gaps in implementing palliative care as a standard of care. METHODS: Cross sectional online survey about the palliative care domains determined by the Psychosocial Care of Children with Cancer and Their Families Workgroup. SUBJECTS: A total of 142 surveys were completed with representation from 18 countries and 39 states. RESULTS: Three-fourths of sites reported having a PPC program available for the pediatric cancer population at their center. Over one-fourth (28%) have been in existence less than five years. Fewer than half of sites (44%) offered 24/7 access to palliative care consultations. Neither hospital-based nor local community hospice services were available for pediatric patients at 24% of responding sites. A specific inpatient PPC unit was available at 8% of sites. Criteria for automatic palliative referrals ("trigger" diagnoses) were reported by 44% respondents. The presence of such "triggers" increased the likelihood of palliative principle introduction 3.41 times (p < 0.003). Six percent of respondents perceived pediatric oncology patients and their families "always" were introduced to palliative care concepts and 17% reported children and families "always" received communication about palliative principles. The most prevalent barriers to palliative care were at the provider level. DISCUSSION: Children and adolescents with cancer do not yet receive concurrent palliative care as a universal standard. PMID- 29173031 TI - Probing the interaction of silver nanoparticles with tau protein and neuroblastoma cell line as nervous system models. AB - Interestingly pharmaceutical sciences are using nanoparticles (NPs) to design and develop nanomaterials-based drugs. However, up to recently, it has not been well realized that NPs themselves may impose risks to the biological systems. In this study, the interaction of silver nanoparticles (AgNPs) with tau protein and SH SY5Y neuroblastoma cell line, as potential nervous system models, was examined with a range of techniques including intrinsic fluorescence spectroscopy, circular dichroism (CD) spectroscopy, 3-(4,5-dimethylthiazol-2-Yl)-2,5 diphenyltetrazolium bromide (MTT) assay, and acridine orange/ethidium bromide (AO/EB) dual staining method. Fluorescence study showed that AgNPs with a diameter of around 10-20 nm spontaneously form a static complex with tau protein via hydrogen bonds and van der Waals interactions. CD experiment revealed that AgNPs did not change the random coil structure of tau protein. Moreover, AgNPs showed to induce SH-SY5Y neuroblastoma cell mortality through fragmentation of DNA which is a key feature of apoptosis. In conclusion, AgNPs may induce slight changes on the tau protein structure. Also, the concentration of AgNPs is the main factor which influences their cytotoxicity. Since, all adverse effects of NPs are not well detected, so probably additional more specific testing would be needed. PMID- 29173033 TI - Evaluation of Alzheimer's disease progression based on clinical dementia rating scale with missing responses and covariates. AB - In clinical trials, patient's disease severity is usually assessed on a Likert type scale. Patients, however, may miss one or more follow-up visits (non monotone missing). The statistical analysis of non-Gaussian longitudinal data with non-monotone missingness is difficult to handle, particularly when both response and time-dependent covariates are subject to such missingness. Even when the number of patients with intermittent missing data is small, ignoring those patients from analysis seems to be unsatisfactory. The focus of the current investigation is to study the progression of Alzheimer's disease by incorporating a non-ignorable missing data mechanism for both response and covariates in a longitudinal setup. Combining the cumulative logit longitudinal model for Alzheimer's disease progression with the bivariate binary model for the missing pattern, we develop a joint likelihood. The parameters are then estimated using the Monte Carlo Newton Raphson Expectation Maximization (MCNREM) method. This approach is quite easy to handle and the convergence of the estimates is attained in a reasonable amount of time. The study reveals that apolipo-protein plays a significant role in assessing a patient's disease severity. A detailed simulation has also been carried out for justifying the performance of our approach. PMID- 29173032 TI - Impact of SNP-SNP interaction among ABCB1, ARRB2, DRD1 and OPRD1 on methadone dosage requirement in Han Chinese patients. AB - AIM: To evaluate the potential association of the genetic polymorphisms in ABCB1, ARRB2, DRD1 and OPRD1 genes with methadone dosage requirement among Han Chinese opioid-dependent patients. MATERIALS & METHODS: Eight SNPs in ABCB1, ARRB2, DRD1 and OPRD1 genes were selected and genotyped using Sequenom MassARRAY platform among 257 methadone maintenance treatment patients. The required information about stable methadone dose, urine analysis for opioid and socio-demographic characteristics was collected. Generalized multifactor dimensionality reduction method was performed to analyze the SNP-SNP interaction. RESULTS: We found that patients carrying the rs529520TG genotype of OPRD1 probably required higher methadone treatment dosage. A 3-locus SNP-SNP interaction pattern (rs1128503 in ABCB1, rs529520 in OPRD1 and rs1045280 in ARRB2) was significantly associated with the methadone dosage requirement (p = 0.029). CONCLUSION: Our results suggested that specific OPRD1 variants and interaction among polymorphisms in ABCB1, OPRD1 and ARRB2 genes contributes to methadone dosage requirement in Han Chinese opioid-dependent patients. PMID- 29173034 TI - Improved petroleum refinery wastewater treatment and seawater desalination performance by combining osmotic microbial fuel cell and up-flow microbial desalination cell. AB - The petroleum refinery wastewater which is a product of petroleum refinery has a high organic content. This study explores the utilization of petroleum refinery wastewater collected from petroleum refinery as a resource for bioelectricity generation and using this energy for salt removal from seawater in a hydraulically connected osmotic microbial fuel cell (OsMFC) and up flow microbial desalination cell (UMDC). Anaerobic mixed sludge was used in the anodic chamber of OsMFC and UMDC. Petroleum refinery wastewater was fed first into the OsMFC and then transferred to the UMDC. The OsMFC and UMDC were connected to 1000 and 100 Omega external resistance respectively. Experimental results showed that the combined system could remove 93% of chemical oxygen demand (COD) from the petroleum refinery wastewater whilst 48% salts were removed from the seawater. Experimental results showed that this complex wastewater can be treated and produce bioelectricity, with COD removal and salt removal. The hydraulically connected OsMFC and up flow MDC provide a suitable platform for wastewater treatment and seawater desalination. PMID- 29173036 TI - Determination and health risk assessment of enrofloxacin, flumequine and sulfamethoxazole in imported Pangasius catfish products in Thailand. AB - The goals of this study were to determine the levels of three antibiotics - enrofloxacin, flumequine and sulfamethoxazole - in Pangasius catfish products imported into Thailand and to assess the health risks from consumption. To extract these antibiotic residues, acetonitrile, methanol and a small amount of formic acid were used as solvents. Determination of the antibiotics after extraction steps was carried out by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) technique. The results showed that 14 and 3 samples of Pangasius catfish products were contaminated with enrofloxacin and sulfamethoxazole, respectively. No flumequine residue was found. While the concentration levels of these antibiotics in most contaminated samples were lower than the European Union (EU) standard, one sample was found to contain sulfamethoxazole at 245.91 ug kg-1, which was higher than the EU standard (100 ug kg-1), indicating the likelihood that some contaminated freshwater fish products are widely distributed in Thai markets. Notably, the concentration levels of enrofloxacin in samples of Pangasius catfish with skin were higher than in non skin products, suggesting that products with skin might retain more antibiotic residues than non-skin products. Although the hazard quotient showed that consuming imported Pangasius catfish products, based on the current consumption rate, will not adversely affect consumer health, antibiotic residues in Pangasius catfish products imported into Thailand should be continually monitored. PMID- 29173037 TI - Can Women Facilitate Men's Prostate Cancer Screening Informed Decision-Making? The M-PACT Trial. AB - The M-PACT study compared an all-male with a mixed-sex intervention to increase informed decision-making for prostate cancer screening among African-American men in church settings. We recruited 262 men in 18 churches randomized to the two intervention approaches. Trained and certified lay peer community health advisors in each church led a series of four men's health workshops on informed decision making for prostate cancer screening. African-American male workshop participants completed baseline, post-workshop, and 12-month follow-up surveys. Contrary to our expectations, including women in the workshops did not result in increased intervention efficacy for the informed decision-making outcomes as both groups showed significant improvement over time in several study outcomes including stage of decision-making for prostate cancer screening, preference for role in decision-making, prostate cancer knowledge, and self-reports of prostate specific antigen testing. Finally, men who attended multiple workshops had better informed decision-making outcomes on several indicators. The current findings suggest mixed results from including women in this men's health educational intervention. Future work should consider optimal ways of providing family support for African American men's health promotion. PMID- 29173038 TI - State of the art of the environmental behaviour and removal techniques of the endocrine disruptor 3,4-dichloroaniline. AB - In recent years, the presence of Endocrine Disrupting Chemicals (EDCs) in wastewater discharges from agricultural and industrial sources, [1] fresh- and estuarine-waters, as well as soils, has been reported in the literature. [2] Studies of adverse changes in wildlife, linked to environmental exposure to these substances, and the suggestion that humans could also be at similar risk of adverse health effects, [3-5] have raised concern for urgent action to understand and reduce such risks. 3,4-Dichloroaniline (3,4-DCA) has been recognized as an EDC, with regards to endocrine disruption data for both wildlife populations and human health. [5] 3,4-DCA is present in the environment as a product of the biodegradation of phenylurea and phenylcarbamate pesticides [6,7] ; furthermore, it can be introduced from industrial and municipal wastewater that is insufficiently purified, or via accidental spills. [8-10] Increasing concentrations of 3,4-DCA in soil and water are the result of its high persistence and accumulation, as well as its low biodegradability. [11,12] Hence, remediation techniques require in-depth study, especially when considering the low removal achieved by traditional activated sludge treatments, and the generation of carcinogenic trihalomethanes as a consequence of the chlorine oxidation methods frequently used in drinking water plants. [13] Fe0/H2O2 systems, photodegradation using doped TiO2, and the use of dielectric barrier discharge reactors, seem to be the most promising techniques for the removal of 3,4-DCA from water. PMID- 29173039 TI - Engineered aglycosylated full-length IgG Fc variants exhibiting improved FcgammaRIIIa binding and tumor cell clearance. AB - FcgammaRIIIa, which is predominantly expressed on the surface of natural killer cells, plays a key role in antibody-dependent cell-mediated cytotoxicity (ADCC), a major effector function of therapeutic IgG antibodies that results in the death of aberrant cells. Despite the potential uses of aglycosylated IgG antibodies, which can be easily produced in bacteria and do not have complicated glycan heterogeneity issues, they show negligible binding to FcgammaRIIIa and abolish the activation of immune leukocytes for tumor cell clearance, in sharp contrast to most glycosylated IgG antibodies used in the clinical setting. For directed evolution of aglycosylated Fc variants that bind to FcgammaRIIIa and, in turn, exert potent ADCC effector function, we randomized the aglycosylated Fc region of full-length IgG expressed on the inner membrane of Escherichia coli. Multiple rounds of high-throughput screening using flow cytometry facilitated the isolation of aglycosylated IgG Fc variants that exhibited higher binding affinity to FcgammaRIIIa-158V and FcgammaRIIIa-158F compared with clinical-grade trastuzumab (Herceptin(r)). The resulting aglycosylated trastuzumab IgG antibody Fc variants could elicit strong peripheral blood mononuclear cell-mediated ADCC without glycosylation in the Fc region. PMID- 29173041 TI - "The deceased has left; the alive has to move on": Experiences of Chinese Widows in the UK. AB - Relatively little is known about the experiences of Chinese widows, especially those living outside China. This qualitative study examines the experiences of eight Chinese or Hong Kong-born widows living in the UK. Using a semistructured approach to interviewing, participants were asked about their lives before, during, and after their spousal bereavement. Five major themes emerged: (1) complexity of marital lives; (2) experiences around the time of the death including fate; (3) loneliness and isolation; (4) the challenges of practical tasks; and finally, (5) current life. The implications of the findings for social policy and practice are briefly discussed. PMID- 29173042 TI - Antithrombin conformational modulation by D-myo-inositol 3,4,5,6 tetrakisphosphate (TMI), a novel scaffold for the development of antithrombotic agents. AB - Antithrombin (AT) is a serpin that inhibits mainly thrombin and fXa after being activated by binding to glycosaminoglycans as heparin and heparan sulfate. Upon binding, the native AT conformation, relatively inactive as a protease inhibitor, is converted to an activated form. Recently, a new compound, named TMI, was discovered in our group with nanomolar affinity to antithrombin, and shown to be able to induce a partial activation of antithrombin. As TMI represents an original scaffold for structural optimizations aiming the development of new antithrombotic drugs, the present work demonstrated, through a series of molecular dynamics simulations, that TMI is able to modulate AT reactive center loop flexibility similarly to what is observed to heparin, as well as exposing AT P1 residue, Arg393. These results represent the first atomic level indication of AT conformational activation by TMI, and may offer a predictive basis for future studies aiming TMI structural optimization. PMID- 29173043 TI - Joint kinetic determinants of starting block performance in athletic sprinting. AB - The aim of this study was to explore the relationships between lower limb joint kinetics, external force production and starting block performance (normalised average horizontal power, NAHP). Seventeen male sprinters (100 m PB, 10.67 +/- 0.32 s) performed maximal block starts from instrumented starting blocks (1000 Hz) whilst 3D kinematics (250 Hz) were also recorded during the block phase. Ankle, knee and hip resultant joint moment and power were calculated at the rear and front leg using inverse dynamics. Average horizontal force applied to the front (r = 0.46) and rear (r = 0.44) block explained 86% of the variance in NAHP. At the joint level, many "very likely" to "almost certain" relationships (r = 0.57 to 0.83) were found between joint kinetic data and the magnitude of horizontal force applied to each block although stepwise multiple regression revealed that 55% of the variance in NAHP was accounted for by rear ankle moment, front hip moment and front knee power. The current study provides novel insight into starting block performance and the relationships between lower limb joint kinetic and external kinetic data that can help inform physical and technical training practices for this skill. PMID- 29173044 TI - Spirituality/religiosity's influence on college students' adjustment to bereavement: A systematic review. AB - Bereavement is prevalent among college students and spirituality/religiosity may play an important role in their bereavement adjustment. This is the first systematic review to investigate the spirituality/religiosity's relationship with bereavement among college students. We searched 10 databases and screened 598 studies. Eight studies met the inclusion criteria. Findings suggested a favorable association of spirituality/religiosity with desirable bereavement adjustment outcomes (growth, spiritual wellbeing, and psychological wellbeing), but mixed association with undesirable bereavement outcomes (distress). We provided directions for future research to further investigate the complex relationship between spirituality/religiosity and bereavement and to refine the meaning-making coping model for the college student population. PMID- 29173045 TI - Multiplicity issues in exploratory subgroup analysis. AB - The general topic of subgroup identification has attracted much attention in the clinical trial literature due to its important role in the development of tailored therapies and personalized medicine. Subgroup search methods are commonly used in late-phase clinical trials to identify subsets of the trial population with certain desirable characteristics. Post-hoc or exploratory subgroup exploration has been criticized for being extremely unreliable. Principled approaches to exploratory subgroup analysis based on recent advances in machine learning and data mining have been developed to address this criticism. These approaches emphasize fundamental statistical principles, including the importance of performing multiplicity adjustments to account for selection bias inherent in subgroup search. This article provides a detailed review of multiplicity issues arising in exploratory subgroup analysis. Multiplicity corrections in the context of principled subgroup search will be illustrated using the family of SIDES (subgroup identification based on differential effect search) methods. A case study based on a Phase III oncology trial will be presented to discuss the details of subgroup search algorithms with resampling-based multiplicity adjustment procedures.

PMID- 29173047 TI - Epidemiological, clinical and laboratory profile of scrub typhus cases detected by serology and RT-PCR in Kumaon, Uttarakhand: a hospital-based study. AB - We analysed the epidemiology, clinical and laboratory data of the 168 scrub typhus cases confirmed by a combination of any one of the following: real time polymerase chain reaction (RT-PCR) and/or immunofluorescence assay (IFA) (IgM and/or IgG). The peak season for scrub typhus was from July to October. By multivariate binary logistic regression analysis, the risk of scrub typhus was about four times in those working in occupation related to forest work. Major clinical manifestations were fever (100%), myalgia (65%), cough (51%) and vomiting (46%); major complications were meningitis/meningoencephatilitis (12.5%) and multi-organ failure (MOF) and pneumonia (5.3% each). Laboratory investigations revealed raised aminotranferase levels and thrombocytopenia in most confirmed cases. We conclude that scrub typhus is an important cause of febrile illness in the Kumaon hills of Uttarakhand where this disease had not previously been considered to exist. PMID- 29173048 TI - Nonspecific Symbiosis Between Sophora flavescens and Different Rhizobia. AB - We explored the genetic basis of the promiscuous symbiosis of Sophora flavescens with diverse rhizobia. To determine the impact of Nod factors (NFs) on the symbiosis of S. flavescens, nodulation-related gene mutants of representative rhizobial strains were generated. Strains with mutations in common nodulation genes (nodC, nodM, and nodE) failed to nodulate S. flavescens, indicating that the promiscuous nodulation of this plant is strictly dependent on the basic NF structure. Mutations of the NF decoration genes nodH, nodS, nodZ, and noeI did not affect the nodulation of S. flavescens, but these mutations affected the nitrogen-fixation efficiency of nodules. Wild-type Bradyrhizobium diazoefficiens USDA110 cannot nodulate S. flavescens, but we obtained 14 Tn5 mutants of B. diazoefficiens that nodulated S. flavescens. This suggested that the mutations had disrupted a negative regulator that prevents nodulation of S. flavescens, leading to nonspecific nodulation. For Ensifer fredii CCBAU 45436 mutants, the minimal NF structure was sufficient for nodulation of soybean and S. flavescens. In summary, the mechanism of promiscuous symbiosis of S. flavescens with rhizobia might be related to its nonspecific recognition of NF structures, and the host specificity of rhizobia may also be controlled by currently unknown nodulation related genes. PMID- 29173049 TI - Light directed migration of a cluster of cells in the centimeter scale. AB - Protein-based systems for light directed migration of cells have been demonstrated up to distances of several hundred microns, but larger distances in the centimeter scale would allow new possible applications. Light activated migration in mammalian cells can be achieved by cells expressing channelrhodopsin 2 and an engineered Ca2+ sensitive Rac1 protein called RACer. In this study, light was used to induce wound healing, localize cells into a region of interest, and move cells over centimeter scale distances. Given the spatially complex organization of different types of cells in real tissue, light directed migration over the centimeter scale could potentially organize cell type arrangement to help develop more realistic tissues for transplantation. PMID- 29173051 TI - Suicide rates and information seeking via search engines: A cross-national correlational approach. AB - The volume of Google searches for suicide-related terms is positively associated with suicide rates, but previous studies used data from specific, restricted geographical contexts, thus, limiting the generalizability of this finding. We investigated the correlation between suicide-related search volume and suicide rates of 50 nations from five continents. We found a positive correlation between suicide rates and search volume, even after controlling for the level of industrialization. Results give credence to the global existence of a correlation. However, the reason why suicide-related search volume is higher in countries with higher suicide rates is still unclear and up to future research. PMID- 29173050 TI - Measles vaccination: Threat from related veterinary viruses and need for continued vaccination post measles eradication. AB - Measles virus (MV) is the only human virus within the morbillivirus genus of the Paramyxoviridae. The veterinary members are canine distemper virus (CDV), peste des petits ruminants virus (PPRV), Rinderpest Virus (RPV) as well as the marine morbilliviruses phocine distemper virus (PDV), dolphin morbillivirus (DMV) and porpoise morbillivirus (PMV). Morbilliviruses have a severe impact on humans and animal species. They confer diseases which have contributed to morbidity and mortality of the population on a global scale. There is substantial evidence from both natural and experimental infections that morbilliviruses can readily cross species barriers. Of most concern with regard to zoonosis is the more recently reported fatal infection of primates in Japan and China with strains of CDV which have adapted to this host. The close genetic relationship, shared cell entry receptors and similar pathogenesis between the morbilliviruses highlights the potential consequences of complete withdrawal of MV vaccination after eradication. Therefore, it would be prudent to continue the current MV vaccination. Ultimately development of novel, safe vaccines which have higher efficacy against the veterinary morbilliviruses is a priority. These would to protect the human population long term against the threat of zoonosis by these veterinary viruses.

AB - Alfred Walter Campbell (1868-1937) established the basic cytoarchitectonic structure of the human brain while he was working as a pathologist at the Rainhill Lunatic Asylum near Liverpool in the United Kingdom. He returned to Australia in 1905 and continued doing research while establishing a neurological practice. His research over the next 17 years focused on four topics: (a) localisation in the cerebellum, (b) the neuroses and psychoses in war, (c) localisation in the cerebral cortex of the gorilla, and (d) the causes and pathology of the mysterious Australian "X" Disease (later known as Murray Valley encephalitis). In this article, I elaborate on his research in these areas, which provided evidence (a) against Louis Bolk's thesis that variation in the size of the cerebellar cortex reflected variation in the amount of cortex controlling various groups of muscle, (b) against the view that the neuroses and psychoses in war were different from those in civilian life, (c) for a parcelation of the cortex of the gorilla brain that supported his earlier findings in the higher apes, and (d) on the cause and pathophysiology of Australian "X" disease. Much of this research was overlooked, but it remains of considerable value and historical significance.

AB - This declaration, signed by an interdisciplinary task force of 234 experts from 83 different countries with different backgrounds, highlights the threat posed by antimicrobial resistance and the need for appropriate use of antibiotic agents and antifungal agents in hospitals worldwide especially focusing on surgical infections. As such, it is our intent to raise awareness among healthcare workers and improve antimicrobial prescribing. To facilitate its dissemination, the declaration was translated in different languages. PMID- 29173055 TI - An Aristotelian view of therapists' practice in multifamily therapy for young adults with severe eating disorders. AB - BACKGROUND: Eating disorders are serious conditions which also impact the families of adult patients. There are few qualitative studies of multifamily therapy with adults with severe eating disorders and none concerning the practice of therapists in multifamily therapy. OBJECTIVES: The aim of the study is to explore therapists' practice in multifamily therapy. Research design and participants: A grounded theory approach was chosen. Data were collected through participant observation in two multifamily therapy groups and qualitative interviews with the therapists in those groups. Ethical considerations: The study conforms to the principles outlined in the Declaration of Helsinki. All participants in the multifamily therapy groups received information about the research project and signed consent forms. The data are treated confidentially and anonymised. FINDINGS: The core category was identified as 'having many strings to one's bow', consisting of three subcategories: 'planning and readjusting', 'developing as therapist and team' and 'regulating the temperature of the group'. This article discusses the empirical findings in the frame of Aristotelian virtue ethics. PMID- 29173056 TI - Enhancing the professional dignity of midwives: A phenomenological study. AB - BACKGROUND: When midwives are not treated with respect and their professional competencies are not recognised, their professional dignity is violated. OBJECTIVE: This study explored and described how the professional dignity of midwives in the selected hospital can be enhanced based on their experiences. RESEARCH DESIGN: A descriptive phenomenological research design was used with in depth interviews conducted with 15 purposely selected midwives. Ethical considerations: The Faculty of Health Sciences Research Ethics Committee of the University of Pretoria approved the study. The research was conducted in an academic tertiary hospital with voluntary participants. FINDINGS: To dignify midwives it is essential to enhance the following: 'to acknowledge the capabilities of midwives', 'to appreciate interventions of midwives', 'to perceive midwives as equal health team members', 'to invest in midwives', 'to enhance collegiality', 'to be cared for by management' and 'to create conducive environments'. CONCLUSION: The professional dignity of midwives is determined by their own perspectives of the contribution that they make to the optimal care of patients, the respect that they get from others and the support that hospital management gives them. With support and care, midwives' professional dignity is enhanced. Midwives will strive to render excellent services as well as increasing their commitment. PMID- 29173057 TI - Microbial composition of biofilm treating wastewater rich in bisphenol A. AB - Although microbial degradation plays a major role in the removal of bisphenol A (BPA) from water environments, there is little information on the effect of BPA on microorganisms in wastewater treatment systems. The aim of this study was to determine the dynamics of the microbial communities in biofilm growing on porous ceramic supports in a column up-flow reactor during exposure to BPA at increasing concentrations from 0 to 10 mg L-1. Independent of BPA load, the efficiency of BPA removal was about 90%. Groups of microorganisms that differ in their sensitivity to the presence of BPA in wastewater were identified. The core microbial genera in the biofilm were Acidovorax, Pseudoxanthomonas and Acinetobacter. Arenimonas sp., Thauera sp. and Acidobacterium sp. were the main components of the biofilm in the absence of BPA in wastewater. Increased abundances of Pseudomonas sp., Acidovorax sp. and Luteimonas sp. in BPA-exposed biofilm indicate that these genera may have played important roles in BPA biodegradation. A correlation between Pseudomonas sp. abundance and BPA removal efficiency indicates that BPA was used directly as a source of carbon and energy for growth. This study indicates that the use of the biofilm reactor enables effective BPA removal from wastewater and expands knowledge about the microbial structure of communities responsible for BPA degradation. PMID- 29173058 TI - Examining youth and caregiver reports of depression and anxiety in families seeking eating disorder treatment. AB - This study examines discrepancies between adolescent and caregiver reports of youth internalizing symptoms in families presenting for an initial eating disorder assessment. Initial diagnostic assessments of 49 adolescent-caregiver dyads seeking treatment at an urban pediatric hospital eating disorder clinic were utilized to examine differences between youth and caregiver reports of youth anxiety and depression symptoms. Caregivers reported significantly higher scores of major depression and generalized anxiety than adolescents (p=.000). Caregivers of youth with more severe ED symptoms exhibited more congruence with youth's own reports of their depression and anxiety. Our results suggest that agreement within families regarding comorbid psychological concerns may be beneficial in promoting treatment uptake for those who desire a reduction in depression and anxiety symptoms, regardless of motivation to change eating behaviors.

AB - AIM: Our aim was to inhibit trypanothione reductase (TR) and P-gp efflux pump of Leishmania by the use of thiolated polymers. Thus, increasing the intracellular accumulation and therapeutic effectiveness of antimonial compounds. METHODS: Mannosylated thiolated chitosan and mannosylated thiolated chitosan polyethyleneimine graft were synthesized and characterized. Meglumine antimoniate loaded nanoparticles were prepared and evaluated for TR and P-gp efflux pump inhibition, biocompatibility, macrophage uptake and antileishmanial potential. RESULTS: Thiomers inhibited TR with Ki 2.021. The macrophage uptake was 33.7- and 18.9-fold higher with mannosylated thiolated chitosan-polyethyleneimine graft and mannosylated thiolated chitosan nanoparticles, respectively, as compared with the glucantime. Moreover, the in vitro antileishmanial activity showed 14.41- and 7.4 fold improved IC50 for M-TCS-g-PEI and M-TCS, respectively as compared with glucantime. CONCLUSION: These results encouraged the concept that TR and P-gp inhibition by the use of thiomers improves the therapeutic efficacy of antimonial drugs. PMID- 29173061 TI - Targeted Sequencing of Malignant Supratentorial Pediatric Brain Tumors Demonstrates a High Frequency of Clinically Relevant Mutations. AB - Pediatric brain tumors cause more deaths than any other childhood malignancy, and the identification of potentially actionable genomic alterations in this rare heterogeneous group of tumors may improve treatment and outcome. The genetic landscape of common posterior fossa tumors has been described in the past several years, yet the classification of malignant pediatric supratentorial tumors remains controversial. Next-generation sequencing (NGS) is a promising tool to evaluate multiple genes concurrently. The clinical utility of NGS has not been proven in pediatric brain tumors. We identified patients diagnosed with high grade supratentorial pediatric brain tumors resected between 2008 and 2012 at our institution. DNA from 12 formalin-fixed paraffin-embedded tumor samples from 9 patients was analyzed, including 3 paired samples from diagnosis and relapse. A panel of 194 cancer-related genes was sequenced using targeted next-generation deep sequencing. Genetic findings were correlated with histology, immunohistochemistry, treatment, and survival. We found one or more pathologic genetic change (mutation, amplification, or deletion) in 8 of 9 (89%) of patients studied. Epidermal Growth Factor Receptor ( EGFR) mutations were found in 3 patients, 2 of which had an exon 20 insertion not previously described in pediatric malignancy. Additional genetic changes were found in EGFR and Platelet Derived Growth Factor Receptor Alpha ( PDGFRA) at relapse not present in the initial samples. Familial cancer predisposition syndromes were suggested by mutations found in 3 genes in 4 patients, including TP53, MSH2, and CHEK2. Seven of 9 patients in this study died of their disease. In summary, targeted deep sequencing may be used in rare pediatric brain tumors to identify driver mutations for targeted therapy, suggest constitutional and familial testing for cancer predisposition syndromes, and select molecular targets worthy of further study.

PMID- 29173063 TI - Development of a pre-glycoengineered CHO-K1 host cell line for the expression of antibodies with enhanced Fc mediated effector function. AB - Novel biotherapeutic glycoproteins, like recombinant monoclonal antibodies (mAbs) are widely used for the treatment of numerous diseases. The N-glycans attached to the constant region of an antibody have been demonstrated to be crucial for the biological efficacy. Even minor modifications of the N-glycan structure can dictate the potency of IgG effector functions such as the antibody-dependent cell mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). Here, we present the development of a glycoengineered CHO-K1 host cell line (HCL), stably expressing beta1,4-N-Acetylglucoseaminyltransferase III (GnT-III) and alpha-mannosidase II (Man-II), for the expression of a-fucosylated antibodies with enhanced Fc-mediated effector function. Glycoengineered HCLs were generated in a two-step strategy, starting with generating parental HCLs by stable transfection of CHO-K1 cells with GnT-III and Man-II. In a second step, parental HCLs were stably transfected a second time with these two transgenes to increase their copy number in the genetic background. Generated glycoengineered CHO-K1 cell lines expressing two different mAbs deliver antibody products with a content of more than 60% a-fucosylated glycans. In-depth analysis of the N-glycan structure revealed that the majority of the Fc-attached glycans of the obtained mAbs were of complex bisected type. Furthermore, we showed the efficient use of FcgammaRIIIa affinity chromatography as a novel method for the fast assessment of the mAbs a-fucosylation level. By testing different cultivation conditions for the pre-glycoengineered recombinant CHO-K1 clones, we identified key components essential for the production of a-fucosylated mAbs. The prevalent effect could be attributed to the trace element manganese, which leads to a strong increase of a fucosylated complex- and hybrid-type glycans. In conclusion, the novel pre glycoengineered CHO-K1 HCL can be used for the production of antibodies with high ratios of a-fucosylated Fc-attached N-glycans. Application of our newly developed FcgammaRIIIa affinity chromatography method during cell line development and use of optimized cultivation conditions can ultimately support the efficient development of a-fucosylated mAbs. PMID- 29173064 TI - Pharmacogenetics of drug-induced ototoxicity caused by aminoglycosides and cisplatin. AB - Aminoglycosides and the anticancer drug cisplatin can cause permanent hearing loss, which impacts patients' quality of life and results in considerable subsequent costs. Since patients' individual susceptibility to aminoglycoside- and cisplatin-induced ototoxicity varies considerably, strategies are needed to identify patients at risk, who may require alternative treatments or specific protection strategies. For both drugs, various genetic variants were linked to an increased or decreased risk for ototoxicity. Except for the association between the A1555G mitochondrial DNA mutation and aminoglycoside ototoxicity, their evidence is considered low because study cohorts were often small and replication studies either missing or contradictory. This review summarizes the pharmacogenetic markers linked to aminoglycoside- or cisplatin-induced ototoxicity and discusses reasons for replication failure and future perspective. PMID- 29173065 TI - Neurobehavioural effects of Lactobacillus rhamnosus GG alone and in combination with prebiotics polydextrose and galactooligosaccharide in male rats exposed to early-life stress. AB - Early life is a period of significant brain development when the brain is at its most plastic and vulnerable. Stressful episodes during this window of development have long-lasting effects on the central nervous system. Rodent maternal separation (MS) is a reliable model of early-life stress and induces alterations in both physiology and behaviour. Intriguingly, the gut microbiota of MS offspring differ from that of non-separated offspring, suggesting a mechanistic role for the microbiota-gut-brain axis. Hence, we tested whether dietary factors known to affect the gut microbiota alter the neurobehavioural effects of MS. The impact of consuming diet containing prebiotics polydextrose (PDX) and galactooligosaccharide (GOS) alone or in combination with live bacteria Lactobacillus rhamnosus GG (LGG) from weaning onwards in rats subjected to early life MS was assessed. Adult offspring were assessed for anxiety-like behaviour in the open field test, spatial memory using the Morris water maze, and reactivity to restraint stress. Brains were examined via PCR for changes in mRNA gene expression. Here, we demonstrate that diets containing a combination of PDX/GOS and LGG attenuates the effects of early-life MS on anxiety-like behaviour and hippocampal-dependent learning with changes to hippocampal mRNA expression of genes related to stress circuitry, anxiety and learning. PMID- 29173066 TI - Expression of genes related to antioxidant activity in Nile tilapia kept under salinity stress and fed diets containing different levels of vitamin C. AB - The aim of this study was to examine whether (1) severe changes in salinity produced increased stress, and (2) vitamin C supplementation might reduce the observed damage in Nile tilapia. The parameters measured included condition factor, survival rate, and gene expression of catalase (CAT), heat shock protein 70 (HSP70), glutathione reductase (GSR), glutathione synthase (GSS), and glutathione peroxidase (GPx). The investigation was conducted with 160 Nile tilapia divided into four treatment groups: freshwater; 7 or 21 parts per thousand (0/00) salinity, all fed a basal diet; as well as a fourth treatment group consisting of fish kept at 210/00 salinity fed a diet supplemented with vitamin C (1500 mg/kg). For gene expression analysis, liver samples were collected after 24 h or after 14 d. After 24 h, fish raised in 210/00 salinity and fed with the diet supplemented with vitamin C showed similar GPx expression as the control freshwater group. GSS expression in 210/00 salinity was similar to fish exposed to 70/00 salinity. Nile tilapia exposed to 210/00 salinity without vitamin C supplementation exhibited the highest HSP70 gene expression levels after 24 h. After 14-dtreatment, the lowest survival rate was observed in the 210/00 salinity group. After 14 d, the highest expression of GPx and GSR levels was detected in fish in the 210/00 salinity group that received vitamin C. Data indicate that vitamin C supplementation enhanced the expression of genes related to antioxidant capacity in Nile tilapia exposed to higher salinity, thereby increasing protection against the oxidative effects induced by high water salinity..

AB - Oxidative stress may cause a wide variety of free radical reactions to produce deleterious modifications in membranes, proteins, enzymes, and DNA. Reactive Oxygen Species (ROS) generated by myeloperoxidase (MPO) can induce lipid peroxidation and also play an important role in the generation of reactive chlorinating and brominating species. As the universal biomarkers, chemical, and immunochemical approach on oxidatively modified and halogenated tyrosines has been carried out. As amido-type adduct biomarkers, chemical, and immunochemical evaluation of hexanoyl- and propanoyl-lysines, hexanoyl- and propanoyl-dopamines and phospholipids were prepared and developed for application of evaluation of novel antioxidative functional food factors. We have also involved in application of oxidatively modified DNAs such as 8-hydroxy- and 8-halogenated deoxyguanosines as the useful biomarkers for age-related diseases using both in vitro and in vivo systems. Application of these oxidative stress biomarkers for novel type of functional food development and recent approach for development of novel evaluation systems are also discussed. PMID- 29173069 TI - Direct Detection of Vibrio vulnificus, Vibrio parahaemolyticus, and Vibrio alginolyticus from Clinical and Environmental Samples by a Multiplex Touchdown Polymerase Chain Reaction Assay. AB - BACKGROUND: Vibrio vulnificus, V. alginolyticus, and V. parahaemolyticus are commonly and opportunistically pathogenic to humans. METHODS: In this study, a novel multiple touchdown polymerase chain reaction method (MT-PCR) was developed to benefit rapid and simultaneous detection of the presence of the three Vibrio species from the enriched clinical and environmental samples. RESULTS: The method showed a sensitivity of 104 colony forming units (CFU)/mL for V. vulnificus, 103 CFU/mL for V. parahaemolyticus and V. alginolyticus, and a specificity of 100% for all the three Vibrio species. All strains of the three Vibrio species were detected in the spiked samples artificially contaminated with reference strains and were identified directly from the enriched clinical and environmental samples within three hours by this MT-PCR assay. All the corresponding bacteria were isolated from these enriched samples in 48 hours by standard microbiologic procedures. CONCLUSIONS: This MT-PCR method, which can detect V. vulnificus, V. parahaemolyticus, and V. alginolyticus directly and simultaneously, was rapid, sensitive, specific, and can be used in clinical diagnostics, food industry studies, and risk assessment of environment. PMID- 29173070 TI - Generalist versus Subspecialist Characteristics of the U.S. Radiologist Workforce. AB - Purpose To assess subspecialty practice characteristics of the U.S. radiologist workforce. Materials and Methods This study used the Medicare Physician and Other Supplier Public Use File and did not constitute human subject research. The authors identified 33 090 radiologists who billed for professional services between 2012 and 2014 and used a validated classification system to map services to seven subspecialties and quantify subspecialty-focused effort on the basis of work relative value units (RVUs). Radiologists with more than half of their billed work RVUs in a single subspecialty were designated subspecialists; the remainder were classified as generalists. Matching radiologists with various characteristics extracted from other publicly available data sets, associations were explored through use of analysis of variance and multivariable logistic regression. Results More than half (55.3%) of U.S. radiologists practice predominantly as generalists but dedicate on average 36.0% effort to one subspecialty. Among radiologists practicing as majority subspecialists, neuroradiologists (10.1% of all radiologists) and breast imagers (8.4%) are most common. Subspecialization is more common (P < .001) among radiologists who are female, are earlier in their career, work in larger practices, have academic affiliations, and practice in the Northeast. By subspecialty, female representation varies from 8.6% (interventional radiology) to 63.1% (breast imaging); cardiothoracic imagers were more commonly early career radiologists, and nuclear medicine physicians were later career radiologists. Subspecialization is considerably more common in larger (>=100 members) practices (63.1%). An academic affiliation is the strongest independent predictor of subspecialization (odds ratio, 3.56; 95% confidence interval: 3.30, 3.84). Conclusion Despite an increased focus on radiology subspecialization, most U.S. radiologists are majority general radiologists on the basis of their work RVUs. Subspecialization is by far more prevalent in larger and academic practices. (c) RSNA, 2017 Online supplemental material is available for this article. PMID- 29173071 TI - Systematic Review and Meta-Analysis of CT Features for Differentiating Complicated and Uncomplicated Appendicitis. AB - Purpose To perform a systematic review and meta-analysis to identify computed tomographic (CT) features for differentiating complicated appendicitis in patients suspected of having appendicitis and to summarize their diagnostic accuracy. Materials and Methods Studies on diagnostic accuracy of CT features for differentiating complicated appendicitis (perforated or gangrenous appendicitis) in patients suspected of having appendicitis were searched in Ovid-MEDLINE, EMBASE, and the Cochrane Library. Overlapping descriptors used in different studies to denote the same image finding were subsumed under a single CT feature. Pooled diagnostic accuracy of the CT features was calculated by using a bivariate random effects model. CT features with pooled diagnostic odds ratios with 95% confidence intervals not including 1 were considered as informative. Results Twenty-three studies were included, and 184 overlapping descriptors for various CT findings were subsumed under 14 features. Of these, 10 features were informative for complicated appendicitis. There was a general tendency for these features to show relatively high specificity but low sensitivity. Extraluminal appendicolith, abscess, appendiceal wall enhancement defect, extraluminal air, ileus, periappendiceal fluid collection, ascites, intraluminal air, and intraluminal appendicolith showed pooled specificity greater than 70% (range, 74% 100%), but sensitivity was limited (range, 14%-59%). Periappendiceal fat stranding was the only feature that showed high sensitivity (94%; 95% confidence interval: 86%, 98%) but low specificity (40%; 95% confidence interval, 23%, 60%). Conclusion Ten informative CT features for differentiating complicated appendicitis were identified in this study, nine of which showed high specificity, but low sensitivity.

AB - Despite widespread understanding of the benefits of physical activity, many adults in the United States do not meet recommended exercise guidelines. Burgeoning technologies, including wearable fitness trackers (e.g., Fitbit, Apple watch), bring new opportunities to influence physical activity by encouraging users to track and share physical activity data and compete against their peers. However, research has not explored the social processes that mediate the relationship between the use of wearable fitness trackers and intention to exercise. In this study, we applied the Theory of Planned Behavior (Ajzen, 1991) to explore the effects of two communicative features of wearable fitness devices social sharing and social competing-on individuals' intention to exercise. Drawing upon surveys from 238 wearable fitness tracker users, we found that the relationship between the two communication features (social sharing and competing) and exercise intention was mediated by attitudes, subjective norms, and perceived behavioral control. The results suggest that the ways in which exercise data are shared significantly influence the exercise intentions, and these intentions are mediated by individuals' evaluation of exercise, belief about important others' approval of exercise, and perceived control upon exercise. PMID- 29173073 TI - In vivo assessment of plant extracts for control of plant diseases: A sesquiterpene ketolactone isolated from Curcuma zedoaria suppresses wheat leaf rust. AB - As an alternative to synthetic pesticides, natural materials such as plant extracts and microbes have been considered to control plant diseases. In this study, methanol extracts of 120 plants were explored for in vivo antifungal activity against Rhizoctonia solani, Botrytis cinerea, Phytophthora infestans, Puccinia triticina, and Blumeria graminis f. sp. hordei. Of the 120 plant extracts, eight plant extracts exhibited a disease control efficacy of more than 90% against at least one of five plant diseases. In particular, a methanol extract of Curcuma zedoaria rhizomes exhibited strong activity against wheat leaf rust caused by P. triticina. When the C. zedoaria methanol extracts were partitioned with various solvents, the layers of n-hexane, methylene chloride, and ethyl acetate showed disease control values of 100, 80, and 43%, respectively, against wheat leaf rust. From the C. zedoaria rhizome extracts, an antifungal substance was isolated and identified as a sesquiterpene ketolactone based on the mass and nuclear magnetic resonance spectral data. The active compound controlled the development of rice sheath blight, wheat leaf rust, and tomato late blight. Considering the in vivo antifungal activities of the sesquiterpene ketolactone and the C. zedoaria extracts, these results suggest that C. zedoaria can be used as a potent fungicide in organic agriculture. PMID- 29173074 TI - Improving the power to establish clinical similarity in a Phase 3 efficacy trial by incorporating prior evidence of analytical and pharmacokinetic similarity. AB - To improve patients' access to safe and effective biological medicines, abbreviated licensure pathways for biosimilar and interchangeable biological products have been established in the US, Europe, and other countries around the world. The US Food and Drug Administration and European Medicines Agency have published various guidance documents on the development and approval of biosimilars, which recommend a "totality-of-the-evidence" approach with a stepwise process to demonstrate biosimilarity. The approach relies on comprehensive comparability studies ranging from analytical and nonclinical studies to clinical pharmacokinetic/pharmacodynamic (PK/PD) and efficacy studies. A clinical efficacy study may be necessary to address residual uncertainty about the biosimilarity of the proposed product to the reference product and support a demonstration that there are no clinically meaningful differences. In this article, we propose a statistical strategy that takes into account the similarity evidence from analytical assessments and PK studies in the design and analysis of the clinical efficacy study in order to address residual uncertainty and enhance statistical power and precision. We assume that if the proposed biosimilar product and the reference product are shown to be highly similar with respect to the analytical and PK parameters, then they should also be similar with respect to the efficacy parameters. We show that the proposed methods provide correct control of the type I error and improve the power and precision of the efficacy study upon the standard analysis that disregards the prior evidence. We confirm and illustrate the theoretical results through simulation studies based on the biosimilars development experience of many different products. PMID- 29173075 TI - Evaluation of Plasma Growth Factors (VEGF, PDGF, EGF, ANG1, and ANG2) in Patients with Varicose Veins Before and After Treatment with Endovenous Laser Ablation. AB - OBJECTIVE: To measure pre- and postoperative plasma concentrations of growth factors (VEGF, PDGF, EGF, ANG1, and ANG2) in patients with primary lower limb varicose veins (VVs) treated with endovenous laser ablation (EVLA). BACKGROUND: Many studies have explored the potential relationship between primary VVs and growth factors. No previous studies were done for patients treated with EVLA. MATERIALS AND METHODS: Blood samples were obtained from 30 patients with primary VVs undergoing treatment with EVLA before and 1 week after treatment. Similar samples were obtained from 20 healthy matched adults as a control. Plasma concentrations of growth factor derivatives (VEGF, PDGF, EGF, ANG1, and ANG2) were measured through commercially available enzyme-linked immunosorbent assay. RESULTS: There was statistically significant reduction in median plasma growth factor (VEGF, PDGF, EGF, and ANG1) levels in the preoperative group (p = 0.001) when compared with the control group except for ANG2, which showed increased plasma level (p = 0.001). However, values of plasma concentration of those growth factors after treatment with EVLA were nearly equal to the control group, especially in EGF and VEGF (p = 0.564, 0.515, respectively). CONCLUSIONS: The altered plasma concentrations of growth factors VEGF, PDGF, EGF, ANG1, and ANG2 among patients with VVs normalized 1 week after treatment with EVLA compared with the control group. This may support the role of these factors in the pathogenesis of the disease. Future studies may evaluate if these changes can play a prognostic and/or predictive value regarding the adequacy of treatment and the possibility of recurrence. PMID- 29173076 TI - Non-occlusive mesenteric ischemia: two case reports and a short review of the literature. AB - INTRODUCTION: Non-occlusive mesenteric ischemia (NOMI) is an infrequent cause of acute mesenteric ischemia with atypical symptoms and a high mortality. PATIENTS AND METHODS: We report two cases of NOMI characterized by their difference in etiology, treatment and outcome. RESULTS: In the first case, the patient developed NOMI after septic shock, she was successfully treated with surgery. The second patient experienced two episodes of cardiac arrest followed by NOMI. He received only supportive care and died shortly after. We present a short review of the literature, discussing epidemiology, pathophysiology, clinical presentations, diagnosis and management of NOMI. CONCLUSION: NOMI is a rare disease with a difficult diagnosis. Early recognition and treatment with supportive therapy, vasodilator drugs and possibly surgery can significantly lower mortality. PMID- 29173077 TI - Family centred care in the paediatric high dependency unit: Parents' and Staff's perceptions. AB - AIM: This study explored parent and staff perceptions of family centred care (FCC) within a paediatric high dependency in one New Zealand hospital. BACKGROUND: FCC is a partnership approach to healthcare delivery where the child's treatment is aligned to the family's needs. Despite widespread endorsement of FCC, variations between parents and staff in healthcare settings continues to be evident. METHOD: A descriptive qualitative cross-sectional design was used with a convenience sample where written responses for one open ended question from 91 parents and 66 staff resident with their child or working within a paediatric high dependency unit in New Zealand. RESULTS: The parents' responses generated three themes (family, treatment and relationships) and the staff's responses generated two themes (family and treatment). CONCLUSION: Whilst there were similarities in describing the meaning of family centred care between parents and staff, their views on the central focus of this differed. PMID- 29173078 TI - OMICS, Oral Cancer Molecular Landscapes, and Clinical Practice. AB - Molecular pathogenesis of oral cancers continues to be researched by omics systems science biotechnologies. Oral cancers rank as the 13th most common cancer globally. Notably, the burden of oral cancers from the Asian continent is 56.21%, with 26% of the burden contributed by India. Despite easy accessibility of the oral cavity and hence early detection of oral cancers, majority are diagnosed in advanced stages in the Asian countries. Innovation in oral cancer diagnostics, as well as theranostics for precision medicine, would aid their early diagnosis, prognosis, and treatment, not to mention discovery of novel molecular targets for drug development. This expert review offers an analysis of oral cancer biomarkers, including somatic mutations, deregulated expression, epigenetic regulation, and genomic variants associated with oral cancer. We also discuss the implications of the current and emerging oral cancer biomarkers with a view to clinical practice, global health, and make suggestions for the ways forward. PMID- 29173079 TI - What influences intentions to request physician-assisted euthanasia or continuous deep sedation? AB - The increasing prevalence of euthanasia in Belgium has been linked to changing attitudes. Using National health survey data (N = 9651), we investigated Belgian adults' intention to ask a physician for euthanasia or continuous deep sedation in the hypothetical scenario of a terminal illness and examined its connection to sociodemographic and health characteristics. Respectively, 38.3 and 25.8% could envisage asking for euthanasia and continuous deep sedation. Those with very bad to fair subjective health and with depression more likely had an intention to ask for euthanasia, which suggests need for attention in the evaluation of requests from specific patient groups. PMID- 29173080 TI - Eating disorder mental health literacy: What do psychologists, naturopaths, and fitness instructors know? AB - At present, there are no known studies investigating the eating disorder mental health literacy (ED-MHL) of common frontline health providers such as psychologists, naturopaths, and fitness instructors. Little research also exists around practitioner knowledge for the spectrum of eating disorders. The current study sought to fill these research gaps and comprised 115 health practitioners who completed an online survey. A fictional vignette describing a female (Sarah) experiencing a subthreshold bulimic variant without purging was presented alongside common ED-MHL items. Almost 4 in 10 psychologists, 7 in 10 natural therapists, and 8 in 10 fitness instructors failed to detect a general eating disorder, with the latter two groups more likely to believe the problem was a self-esteem issue. Perceived helpfulness of people and interventions varied from best practice clinical guidelines, with physical/medical risk management not prioritized, pharmacotherapy viewed poorly, and doctors seen as one of the least helpful people. Although Sarah's problem was seen as severe and highly common (which may speak to the volume of undetected eating disorders), alarmingly 36.7% of fitness instructors viewed her predicament as desirable given weight lost. This novel study highlights the need for specific training interventions to improve health practitioners' ED-MHL, particularly around atypical eating disorder presentations, which may facilitate earlier detection and help-seeking for evidence-based interventions rather than expenditure on unhelpful or even harmful treatments, leading to improved community health and lives saved.

AB - Drawing on a legacy of Black television and film production, Black web series remediate earlier media forms in order to usher in a twenty-first-century revival of indie Black cultural production. Specifically, video sharing and social media platforms operate as a sphere in which content creators and users are afforded unique opportunities to engage with video content and each other on a variety of levels. Focusing on the YouTube media sphere, one can also observe the myriad ways in which the performance of race, gender, and sexuality influences the types of discourse that circulate within these sites. In watching and analyzing Black queer web series on YouTube, I examine how the performance of gender and sexuality by Black queer women within and outside of web series are policed and protected by both community insiders and outsiders. Utilizing an ethnographic framework, which includes a critical discourse analysis of the YouTube comments for the series Between Women, as well as a textual analysis of series content, this project draws conclusions about the role that the politics of pleasure, performance, and the public sphere play in the recognition and/or refusal of queer sexuality within Black communities. PMID- 29173081 TI - Varicella Virus Vaccination in the United States. AB - Varicella zoster virus (VZV) is the cause of chickenpox (varicella) and shingles (zoster), and was once responsible for over 4 million infections in the United States annually. The development of a live attenuated VZV vaccine was initially viewed with extreme skepticism. Nonetheless, a VZV vaccine was developed in the 1970s by Takahashi and his colleagues in Japan and was eventually licensed in the US. It is now known to be one of the safest and most effective vaccines available and is administered worldwide. Here are described important factors that contributed to the successful research and licensure of the highly successful VZV vaccine. PMID- 29173085 TI - Epigenetics-by-Sex Interaction for Coronary Artery Disease Risk Conferred by the Cystathionine gamma-Lyase Gene Promoter Methylation. AB - Coronary artery disease (CAD) is a major global health burden whereby gene-by environment-by-sex interactions play an important role. Coronary artery bypass graft (CABG) surgery involves patients with well-documented and severe CAD. Hence, the study of CAD in a context of the CABG surgery serves as an advantageous model for disease phenotype ascertainment and genetic association studies. We report here new observations from a case-control genetic association study on promoter methylation of the cystathionine gamma-lyase (CTH) gene and its association with CAD. To the best of our knowledge, this is the first clinical study to show the DNA methylation status of the CTH promoter in relation to this clinical phenotype. CTH encodes for the hydrogen sulfide generating enzyme named CSE in the endothelium that is mechanistically highly relevant for CAD. In a sample of 334 subjects from Greece (178 cases with CAD and who underwent CABG, and 156 controls), CTH promoter methylation was analyzed using a SYBR Green-based quantitative methylation-specific polymerase chain reaction. We found increased methylation in CTH promoter in cases (19.1%) compared to controls (10.3%) (p = 0.024). Gene-by-sex analysis sustained the significant association in men (p = 0.032) but not in women (p = 0.884). By using multivariate analyses after controlling for potential confounders such as smoking, age, and gender, we found that increased CTH gene promoter methylation was associated with CAD in the total sample (odds ratio [OR] = 2.163, 95% confidence interval [CI] 1.038-4.506, p = 0.039) and in men (OR = 2.418, 95% CI 1.048-5.581, p = 0.039) but not in women (OR = 0.542, 95% CI 0.094-3.140, p = 0.495). These observations collectively warrant further precision medicine and biomarker research to examine the CTH methylation status as a putative epigenetic regulator of CAD risk in larger and independent samples. PMID- 29173084 TI - Multi-Drug-Resistant Gram-Negative Infections in Deployment-Related Trauma Patients. AB - BACKGROUND: The contribution of multi-drug-resistant gram-negative bacilli infections (MDRGN-I) in patients with trauma is not well described. We present characteristics of MDRGN-Is among military personnel with deployment-related trauma (2009-2014). PATIENTS AND METHODS: Data from the Trauma Infectious Disease Outcomes Study were assessed for infectious outcomes and microbial recovery. Infections were classified using standardized definitions. Gram-negative bacilli were defined as multi-drug-resistant if they showed resistance to >=3 antibiotic classes or were producers of extended-spectrum beta-lactamase or carbapenemases. RESULTS: Among 2,699 patients admitted to participating U.S. hospitals, 913 (33.8%) experienced >=1 infection event, of which 245 (26.8%) had a MDRGN-I. There were 543 MDRGN-I events (24.6% of unique 2,210 infections) with Escherichia coli (48.3%), Acinetobacter spp. (38.6%), and Klebsiella pneumoniae (8.4%) as the most common MDRGN isolates. Incidence of MDRGN-I was 9.1% (95% confidence interval [CI]: 8.0-10.2). Median time to MDRGN-I event was seven days with 75% occurring within 13 days post-trauma. Patients with MDRGN-Is had a greater proportion of blast injuries (84.1% vs. 62.5%; p < 0.0001), traumatic amputations (57.5% vs. 16.3%; p < 0.0001), and higher injury severity (82.0% had injury severity score >=25 vs. 33.7%; p < 0.0001) compared with patients with either no infections or non-MDRGN-Is. Furthermore, MDRGN-I patients were more frequently admitted to the intensive care unit (90.5% vs. 48.5%; p < 0.0001), colonized with a MDRGN before infection (58.0% vs. 14.7%; p < 0.0001), and required mechanical ventilation (78.0% vs. 28.8% p < 0.0001). Antibiotic exposure before the MDRGN-I event was significantly higher across antibiotic classes except first generation cephalosporins and tetracyclines, which were very commonly used with all patients. Regarding outcomes, patients with MDRGN-Is had a longer length of hospitalization than the comparator group (53 vs. 18 days; p < 0.0001). CONCLUSIONS: We found a high rate of MDRGN-I in our population characterized by longer hospitalization and greater injury severity. These findings inform treatment and infection control decisions in the trauma patient population. PMID- 29173086 TI - Evaluation of ultrasonography guidance for single-puncture temporomandibular joint arthrocentesis: A randomized clinical study. AB - Objective To evaluate ultrasonography (US) guidance on the single-puncture temporomandibular joint (TMJ) arthrocentesis technique. Methods Twenty-four patients were randomly divided into two groups (n = 12 in each group), and single puncture arthrocentesis (SPA) was performed with and without US guidance in groups 1 and 2. During the one-year follow-up period, the groups were statistically evaluated by the visual analog scale for pain, maximum mouth opening, lateral excursion, and protrusion within each group and between the two groups. Results Both treatment groups showed significant improvement, compared to the baseline levels for almost all outcome variables. However, there were no statistically significant differences between groups 1 and 2 (p > 0.05). Conclusion US guidance can be used for cannula placement in SPA. However, the outcome results are the same with or without its use. PMID- 29173087 TI - Influence of process parameters on the effectiveness of photooxidative treatment of pharmaceuticals. AB - In this study, UV-C/H2O2 and UV-C/[Formula: see text] processes as photooxidative Advanced oxidation processes were applied for the treatment of seven pharmaceuticals, either already included in the Directive 2013/39/EU "watch list" (17alpha- ethynylestradiol, 17beta-estradiol) or with potential to be added in the near future due to environmental properties and increasing consumption (azithromycin, carbamazepine, dexamethasone, erythromycin and oxytetracycline). The influence of process parameters (pH, oxidant concentration and type) on the pharmaceuticals degradation was studied through employed response surface modelling approach. It was established that degradation obeys first-order kinetic regime regardless structural differences and over entire range of studied process parameters. The results revealed that the effectiveness of UV-C/H2O2 process is highly dependent on both initial pH and oxidant concentration. It was found that UV-C/[Formula: see text] process, exhibiting several times faster degradation of studied pharmaceuticals, is less sensitive to pH changes providing practical benefit to its utilization. The influence of water matrix on degradation kinetics of studied pharmaceuticals was studied through natural organic matter effects on single component and mixture systems. PMID- 29173088 TI - Reliability and concurrent validity of a motor skill competence test among 4- to 12-year old children. AB - The purpose of this study was to examine the test-retest reliability, internal consistency and concurrent validity of the Athletic Skills Track (AST). During a regular PE lesson, 930 4- to 12-year old children (448 girls, 482 boys) completed two motor skill competence tests: (1) the Korperkoordination-Test fur Kinder (KTK) and (2) an age-related version of the AST (age 4-6 years: AST-1, age 6-9 years: AST-2, and age 9-12 years: AST-3). The test-retest reliability of the AST was high (AST-1: ICC = 0.881 (95% CI: 0.780-0.934); AST-2: ICC = 0.802 (95% CI: 0.717-0.858); and AST-3: ICC = 0.800 (95% CI: 0.669-0.871). The internal consistency, concerning the three age-bands of the AST was above the acceptable level of Cronbach's alpha > 0.70 (AST-1: alpha = 0.764; AST-2: alpha = 0.700; and AST-3: alpha = 0.763). There was a moderate to high correlation between the time to complete the AST, and the age- and gender-related motor quotients of the KTK (AST-1: r = -0.747, p = 0.01; AST-2: r = -0.646, p = 0.01; and AST-3: r = -0.602, p = 0.01). The Athletic Skills Track is a reliable and valid assessment tool to assess motor skill competence among 4- to 12-year old children in the PE setting. PMID- 29173089 TI - Interpersonal needs and psychological pain: The role of brooding and rejection sensitivity. AB - The interpersonal theory of suicide proposes that thwarted belongingness (TB) and perceived burdensomeness (PB) predict psychological pain and desire for suicide. Brooding may be a mechanism in explaining how TB and PB predict pain. The conceptual similarity between rejection sensitivity (RS) and TB suggests that individuals with high RS may be likely to experience psychological pain in the context of TB. To test this model, 155 college students completed measures of psychological pain, TB, PB, brooding, and RS. As predicted, brooding mediated the relations between both TB and PB and psychological pain. RS interacted with TB in predicting psychological pain.

AB - The completion of the zebrafish genome sequence and advances in miniaturization and multiplexing were essential to the creation of techniques such as RNA-seq, ChIP-seq, and high-throughput behavioral and chemical screens. Multiplexing was also instrumental in the recent enhancement of the classic yeast one-hybrid interaction techniques to provide unprecedented discovery capabilities for protein-DNA interactions. Unfortunately its use for zebrafish research is currently hampered by the lack of an open reading frame (ORF) clone collection. As a first step toward a complete collection, we describe a small library of transcriptional regulatory proteins comprising 142 ORFs and its potential applications. PMID- 29173091 TI - Molecular aspects of core-shell intrinsic defect induced enhanced antibacterial activity of ZnO nanocrystals. AB - AIM: To investigate molecular aspects of the antibacterial effect of size dependent core-shell intrinsic defects of nanocrystalline ZnO synthesized through high energy ball milling technique. MATERIALS & METHODS: Mechanically synthesized and characterized 7, 10 and 15 h milled ZnO nanoparticles were evaluated for antibacterial activity with molecular investigation by computational molecular docking. RESULTS: Synthesized ZnO nanoparticles displayed shrinkage of core and increase of shell with reduction in size of bulk ZnO particles from 250 to 80, 40 and 20 nm and increase in zeta potential up to -19 mV in 7, 10 and 15 h nano ZnO. Antibacterial activity was found increased with decrease in size due to increased reactive oxygen species and membrane damage in bacteria. CONCLUSION: Synthesized nano ZnO exhibit size-dependent antibacterial action as consequences of interactions with cell membrane proteins via hydrogen bond interaction with amino acid residues followed by internalization, membrane depolarization and induction of reactive oxygen species generation. PMID- 29173092 TI - Ergogenic effects of precooling with cold water immersion and ice ingestion: A meta-analysis. AB - This review evaluated the effects of precooling via cold water immersion (CWI) and ingestion of ice slurry/slushy or crushed ice (ICE) on endurance performance measures (e.g. time-to-exhaustion and time trials) and psychophysiological parameters (core [Tcore] and skin [Tskin] temperatures, whole body sweat [WBS] response, heart rate [HR], thermal sensation [TS], and perceived exertion [RPE]). Twenty-two studies were included in the meta-analysis based on the following criteria: (i) cooling was performed before exercise with ICE or CWI; (ii) exercise longer than 6 min was performed in ambient temperature >=26 degrees C; and (iii) crossover study design with a non-cooling passive control condition. CWI improved performance measures (weighted average effect size in Hedges' g [95% confidence interval] + 0.53 [0.28; 0.77]) and resulted in greater increase (DeltaEX) in Tskin (+4.15 [3.1; 5.21]) during exercise, while lower peak Tcore ( 0.93 [-1.18; -0.67]), WBS (-0.74 [-1.18; -0.3]), and TS (-0.5 [-0.8; -0.19]) were observed without concomitant changes in DeltaEX-Tcore (+0.19 [-0.22; 0.6]), peak Tskin (-0.67 [-1.52; 0.18]), peak HR (-0.14 [-0.38; 0.11]), and RPE (-0.14 [ 0.39; 0.12]). ICE had no clear effect on performance measures (+0.2 [-0.07; 0.46]) but resulted in greater DeltaEX-Tcore (+1.02 [0.59; 1.45]) and DeltaEX Tskin (+0.34 [0.02; 0.67]) without concomitant changes in peak Tcore (-0.1 [ 0.48; 0.28]), peak Tskin (+0.1 [-0.22; 0.41]), peak HR (+0.08 [-0.19; 0.35]), WBS (-0.12 [-0.42; 0.18]), TS (-0.2 [-0.49; 0.1]), and RPE (-0.01 [-0.33; 0.31]). From both ergogenic and thermoregulatory perspectives, CWI may be more effective than ICE as a precooling treatment prior to exercise in the heat. PMID- 29173093 TI - Molecular network-selected pharmacogenomics in a case of bipolar spectrum disorder. AB - Personal genomic analysis was used for molecular diagnosis and pharmacogenomics in a 53-year-old female suffering from alternating depressive and dysphoric episodes. A total of 52 genes and 108 SNPs were analyzed in the whole genome. Results from the pharmacogenomic analysis were consistent with the pharmacological history and indicate mutations associated with low monoaminergic tone, but also a hyperactive 5HT2A receptor, a feature that associates to a high probability of developing a bipolar condition, especially under 5 hydroxytryptamine potentiating pharmacology. This aligns with the patient developing dysphoria with high clomipramine. The pharmacokinetic genomics pointed out to some absorption, distribution, metabolism, and excretion (ADME) alterations that can lower or nullify drug's activity. A personalized regimen was proposed, with a positive outcome after 1 year. PMID- 29173094 TI - Improving efficiency of an angiotensin converting enzyme inhibitory peptide as multifunctional peptides. AB - Bioactive peptides have been defined as specific protein fragments that have numerous biological activities. The aim of this study was to introduce three multifunctional peptides. Hence, we used rabbit lung angiotensin converting enzyme (ACE) inhibitor peptide AFKDEDTEEVPFR to prepare two analogous peptides KDEDTEEVP and KDEDTEEVH. ACE inhibitory, antioxidant, and antimicrobial activities of three synthetic peptides were investigated. Among the three peptides, KDEDTEEVP exhibited the highest ACE inhibitory activity with IC50 value of 69.63 +/- 2.51 MUM. Furthermore, the results of fluorescence spectroscopy and molecular modeling showed that KDEDTEEVP had more affinity to ACE than other peptides. The peptide of KDEDTEEVH showed the strongest antioxidant scavenging capacity on DPPH radicals (EC50 = 135 +/- 9.62 MUM), hydroxyl radicals (EC50 = 144 +/- 8.73 MUM), and ABTS radicals (EC50 = 62 +/- 4.52%). Moreover, it showed the highest activity in iron-chelating test (EC50 = 226 +/- 14.13 MUM) and could also effectively inhibit the peroxidation of linoleic acid. The antimicrobial activity results showed that KDEDTEEVH had higher efficiency against Gram positive than Gram-negative bacteria with MIC values of higher than 205 +/- 10.75 MUM. Although there was not a direct correlation between ACE inhibitor and antioxidant activity for analogous peptides, both analogous peptides exhibited more efficiency than the mother peptide. Thus, they can be considered as multifunctional peptides and would be beneficial ingredient to be used in food and drug industry. PMID- 29173095 TI - Seasonal variation of cancer mortality in Hungary between 1984 and 2013. AB - AIMS: Despite decreasing trends, Hungary is the leader in cancer mortality among European countries. We examined the seasonal variation of cancer mortality in Hungary between 1984 and 2013. METHODS: Hungarian monthly cancer mortality and population data were used in the analysis. The Walter-Elwood method was used to determine seasonal variation in both mortality rates and proportionate mortality. RESULTS: Significant winter-peak seasonality was found in all-cancer mortality. A similar seasonal trend with a peak from November to January was observed in death rates from colorectal, lung, female breast, prostate, bladder, brain, lymphoid and hematopoietic cancers. However, no more cyclical variation was identified in the mortality rates from other cancers. In addition, significant seasonal variation in proportionate mortality was shown for all cancer sites examined, with a peak in August or September. CONCLUSIONS: This study presents the seasonality pattern of different types of cancer mortality which might be related to environmental factors (e.g. infections). PMID- 29173096 TI - Death in life or life in death? Dementia's ontological challenge. AB - Is it possible to end one's life well with dementia? The perception of dementia as death brought into life flows from ideas about humanness embedded in medicine's Cartesian paradigm. Dementia as incurable brain disease exacerbates negativity. But the real impact of dementia is that it changes social relations: to live well with dementia requires a relational not Cartesian understanding of life. A relational ontology prioritizes social health: to live is to be held in connection. Negativity produces the disconnection that is death, with or without disease. When people with dementia are held in connection, they live a better life. PMID- 29173097 TI - Understanding grief in children who have lost a parent with cancer: How do they give meaning to this experience? Results of an interpretative phenomenological analysis. AB - Though the adjustment of bereaved children is increasingly investigated through quantitative studies, their intimate representations regarding the loss of their parent remain unknown. This qualitative study aims at exploring how they give meaning to this experience. Nondirective interviews with bereaved children were conducted and submitted to an interpretative phenomenological analysis. Fourteen children (8 boys, 6 girls, mean age = 8.5 years) were recruited. Seven major themes depicting their grief experience were identified. The importance of the surviving parent is critically highlighted. Findings suggest that the remaining parent could become a fundamental actor in providing grief support for the bereaved children. PMID- 29173098 TI - Reverse syphilis screening algorithm fails to demonstrate cost effectiveness in persons living with HIV. AB - Although the reverse syphilis screening algorithm is more efficient than the traditional algorithm, it may lead to exorbitant costs for health systems serving persons living with HIV needing annual syphilis screening. Alternatively, the traditional screening algorithm is cost saving in many scenarios. PMID- 29173099 TI - Are the bite force and electromyographic activity altered in muscle TMD patients with abfraction lesions? AB - OBJECTIVE: To verify if the maximal molar bite force (BF) and the electromyographic activity (EMG) are altered in TMD patients with abfraction lesions (AL) when compared to those without AL. METHODS: The sample was composed of 45 patients (18-60 years old), 30 diagnosed with TMD (RDC/TMD) (15 with AL and 15 without AL) and 15 controls. The BF and the EMG of the masticatory muscles (maximal voluntary contraction (MVC) and chewing gum) were measured. RESULTS: TMD patients showed decreased BF (p < 0.001), without differences between patients with and without AL. The electromyographic activity during MVC was similar among all groups (p > 0.05), although there was a greater trend of muscular balance for the control group (percentage overlapping coefficient and electromyographic indexes). The TMD group without AL showed a lower number of cycles and masticatory frequency. DISCUSSION: TMD patients with and without AL exhibited similar results in the analysis of the BF and EMG, without differences. PMID- 29173100 TI - Wastewater treatment with a new electrically enhanced biomass concentrator reactor: trial application and technological perspectives. AB - Biomass concentrator reactors (BCRs) are an alternative wastewater treatment technology developed as a possible solution to membrane bioreactors' (MBRs) high construction and energetic costs. BCRs are an alternative based on the same principle of biomass retention, using a coarser filter medium instead of a membrane. A BCR-derived technology enhanced by an electric field called electrically enhanced biomass concentrator reactor (E2BCR) was developed, designed, and tested for wastewater treatment at different organic loads for a period of 100 days. The electrically enhanced reactor showed better chemical oxygen demand (COD) removal performances that the non-enhanced control reactor (90% and 84%, respectively), and a lower fouling tendency. The E2BCR proved to be more energy efficient in comparison with the control reactor in terms of energy consumption per mass of COD removed. PMID- 29173101 TI - Advancing Global Precision Medicine: An Overview of Genomic Testing and Counseling Services in Malaysia. AB - Precision medicine, genomic and diagnostic services are no longer limited to developed countries. This broadening in geography of biomarker applications and omics diagnostics also demands empirical study of implementation, diagnostic testing, and counseling practices in the field. For example, the Malaysian population has large ethnic diversity and high prevalence of genetic disorders such as hemoglobinopathies and metabolic disorders. Increased morbidity and mortality from such diseases have a direct impact on society and health system sustainability and for this, decision-making becomes of outmost importance. We report here on our findings on the landscape of genomic testing and genetic counseling services in Malaysia. We first defined the framework of all Malaysian stakeholders that offer genomics services and next, we identified the related information gaps, as depicted through the service providers' online websites. Our research framework revealed that there is a very diverse spectrum of genomics services in Malaysia, in which wet- and dry-laboratory services integrate. Moreover, we identify the current gaps and possible remedies to improve the quality of genomic and predictive analytics, not to mention considerations to ensure robust ethics and responsible innovation. To our knowledge, this is the first such study to be performed for a Southeast Asian country. Our genomics and precision medicine services mapping strategy presented in this study may serve as a model for field assessment at regional, national, and international levels as precision medicine is expanding globally and new governance challenges and opportunities continue to emerge for smart implementation science. PMID- 29173102 TI - MoKey: A versatile exergame creator for everyday usage. AB - Currently, virtual applications for physical exercises are highly appreciated as rehabilitation instruments. This article presents a middleware called "MoKey" (Motion Keyboard), which converts standard off-the-shelf software into exergames (exercise games). A configurable set of gestures, captured by a motion capture camera, is translated into the key strokes required by the chosen software. The present study assesses the tool regarding usability and viability on a heterogeneous group of 11 participants, aged 5 to 51, with moderate to severe disabilities, and mostly bound to a wheelchair. In comparison with FAAST (The Flexible Action and Articulated Skeleton Toolkit), MoKey achieved better results in terms of ease of use and computational load. The viability as an exergame creator tool was proven with help of four applications (PowerPoint(r), e-book reader, Skype(r), and Tetris). Success rates of up to 91% have been achieved, subjective perception was rated with 4.5 points (from 0-5). The middleware provides increased motivation due to the use of favorite software and the advantage of exploiting it for exercise. Used together with communication software or online games, social inclusion can be stimulated. The therapists can employ the tool to monitor the correctness and progress of the exercises. PMID- 29173103 TI - Social Norm, Family Communication, and HBV Screening among Asian Americans. AB - Individuals' behaviors are influenced by those of others in their social environment (i.e., descriptive norms), as well as by how individuals perceive they should behave in that environment (e.g., injunctive norms). Although social norms are thought to play an important role in hepatitis B virus (HBV) screening, limited theoretical or empirical guidance exists on how the underlying process works. In addition, norms are social phenomena that are spread through family discussion about the importance of getting HBV screening. Using the theory of normative social behavior (TNSB), this study examined the roles of injunctive norms (IN), descriptive norms (DN), and family discussion in HBV screening behavior among Asian Americans. Data from a survey of Asian Americans in the Baltimore Washington metropolitan area (N = 877) were used to test underlying theoretical propositions. DN and family discussion emerged as key factors in HBV screening behavior among all Asian Americans. IN were associated with HBV screening among Chinese and Korean Americans, but not for Vietnamese Americans. Family discussion moderated the influence of DN on behavior among Chinese and Vietnamese Americans. However, the main effect of DN on screening behavior was not modified by IN (no interactions between DN and IN). The results indicate that family discussion and social norms are integral in enabling Asian Americans to undergo HBV screening and warrant sensitivity in the design and implementation of a liver cancer prevention program in this high-risk group of Asian Americans. PMID- 29173104 TI - Examining the Influence of Relational Aggression on Sexual Satisfaction With Attachment Behaviors as a Potential Mediator. AB - The purpose of this study was to investigate the relationship between relational aggression and sexual satisfaction, as well as to determine if attachment behaviors could mediate this relationship. Data came from the Relate Institute Questionnaire (RELATE) and were drawn from the matched-pair responses of 539 heterosexual married couples. Results showed the greater the perceived relational aggression, the lower the sexual satisfaction for both self and partner, regardless of gender. Mediation analyses suggest that attachment behaviors may be a mechanism through which relational aggression influences sexual satisfaction. Implications for clinicians and future research are discussed. PMID- 29173105 TI - Economic Evaluation of Teledentistry in Cleft Lip and Palate Patients. AB - OBJECTIVE: To assess the use of Teledentistry (TD) in delivering specialist dental services at the Royal Children's Hospital (RCH) for rural and regional patients and to conduct an economic evaluation by building a decision model to estimate the costs and effectiveness of Teledental consultations compared with standard consultations at the RCH. METHODS: A model-based analysis was conducted to determine the potential costs of implementing TD at the RCH. The outcome measure was timely consultations (whether the patient presented within an appropriate time according to the recommended schedule). Dental records at the RCH of those who presented for orthodontic or pediatric dental consultations were assessed. A cost-effectiveness analysis (CEA), comparing TD with the traditional method of consultation, was conducted. One-way sensitivity analysis was performed to test the robustness of the results. Results and Materials: A total of 367 TD appropriate consultations were identified, of which 241 were timely (65.7%). The mean cost of a RCH consultation was A$431.29, with the mean TD consult costing A$294.35. This represents a cost saving of A$136.95 per appointment. The CEA found TD to be a dominant option, with cost savings of A$3,160.81 for every additional timely consult. The model indicated that 36.7 days of clinic time may be freed up at the RCH to treat other patients and expand capacity. These results were robust when performing one-way sensitivity analysis. CONCLUSION: When taking a societal perspective, the implementation of TD is likely to be a cost-effective alternative compared with the standard practice of face-to-face consultation at the RCH. PMID- 29173106 TI - Biodegradation of high concentrations of formaldehyde using Escherichia coli expressing the formaldehyde dismutase gene of Methylobacterium sp. FD1. AB - In the present study, formaldehyde dismutase from Methylobacterium sp. FD1 was partially purified and analyzed by nanoLC-MS/MS; it was then cloned from the genomic DNA of FD1 by PCR. The open reading frame of the formaldehyde dismutase gene of FD1 was estimated to be 1203 bp in length. The molecular weight and pI of formaldehyde dismutase (401 aa), as deduced from the FD1 gene, were calculated at 42,877.32 and 6.56, respectively. NAD(H)-binding residues and zinc-binding residues were found in the amino acid sequence of the deduced formaldehyde dismutase of FD1 by BLAST search. The resting Escherichia coli cells that were transformed with the FD1 formaldehyde dismutase gene degraded high concentrations of formaldehyde and produced formic acid and methanol that were molar equivalents of one-half of the degraded formaldehyde. The lyophilized cells of the recombinant E. coli also degraded high concentrations of formaldehyde. PMID- 29173107 TI - Does Eliminating the Earnings Test Increase the Incidence of Low Income Among Older Women? AB - Reducing or eliminating Social Security's retirement earnings test (RET) can encourage labor supply of older individuals receiving benefits. However, these reforms can encourage earlier claiming of Social Security benefits, permanently lowering future benefits. We explore the consequences, for older women, of eliminating the RET from the full retirement age to age 69 (in 2000), relying on the intercohort variation in exposure to changes in the RET to estimate these effects. The evidence is consistent with the conclusion that eliminating the RET increased the likelihood of having very low incomes among women in their mid-70s and older-ages at which the lower benefits from claiming earlier could outweigh higher income in the earlier period when women or their husbands increased their labor supply. PMID- 29173108 TI - Effects of image congruency on persuasiveness and recall in direct-to-consumer prescription drug advertising. AB - Although direct-to-consumer (DTC) prescription drug advertising is regulated by the U.S. Food and Drug Administration, content analyses suggest advertisers may not disclose drug risks in the same way they describe drug benefits. This study tests the relationship between image congruency in televised DTC advertisements, recall of risks/benefits, and perceived persuasiveness. Advertisements for Nasonex, Advair, and Lunesta were shown to college students in either their original (image incongruent) or modified (image neutral) form. Risks were easier to recall with image-neutral advertisements. Gender also had a significant interaction effect, suggesting that males and females process DTC advertisement differently. PMID- 29173110 TI - How does objective and subjective human papillomavirus knowledge affect information-seeking intentions and source preferences? AB - This study examines the effects of objective (factual information) and subjective knowledge (an individual's self-assessment of how much knowledge they have) on information-seeking intentions and source preferences. It explores the human papillomavirus (HPV) knowledge inequalities in groups of young adults age 18-26 years with and without vaccinations and diagnosis, and different demographics/socio-economic and perceptions of health status. Higher subjective HPV knowledge leads to greater information-seeking intentions from family/friends and mass media but not from health professionals and the Internet. Objective HPV knowledge did not matter for information seeking. The important role of demographics/socio-economic and perceived health status is also discussed. PMID- 29173109 TI - Strategies for recruiting populations to participate in the chronic disease self management program (CDSMP): A systematic review. AB - The purpose of this review was to better understand how to market the Chronic Disease Self-Management Program to new audiences. Eight databases were searched for peer-reviewed studies of the CDSMP. A total of 39 articles were analyzed to describe the theoretical basis of recruitment strategies and their effectiveness while engaging diverse populations. Findings included that female, Caucasian, and elderly groups are overrepresented in CDSMP literature and recruitment efforts have not been explicitly grounded in theory. This review provides insight into trends in CDSMP recruitment and identifies the need for further research regarding the application of marketing theory to future enrollment efforts. PMID- 29173112 TI - "We want to offer you peace of mind": Marketing of transnational commercial surrogacy services to intended parents. AB - The purpose of this research study was to conduct a content analysis of commercial surrogacy websites to explore how surrogacy is marketed to intended parents. The researchers developed a template to code website data, and a total of 345 website pages were reviewed. Websites depicted surrogacy as a solution to a problem, privileged genetic parenthood, ignored the potential for exploitation, dismissed surrogates' capacity to bond with the fetuses they carry, emphasized that surrogacy arrangements are mutually beneficial, ignored structural inequalities, and depicted surrogates as conforming to strict gender roles. These framings introduce vulnerabilities to both intended parents and surrogate mothers. PMID- 29173113 TI - Posterior reversible encephalopathy syndrome possibly induced by pemetrexed maintenance therapy for lung cancer: a case report and literature review. AB - Introduction Advances in systemic chemotherapy, molecular targeted therapy and immunotherapy have extended and improved the quality of life of patients with cancer. However, the central nervous system is very susceptible to complications of systemic cancer and its treatment. Posterior reversible encephalopathy syndrome (PRES) is a rare clinical and neuroradiologic entity which has garnered increasing recognition in the past two decades. Cancer patients are generally treated with cytotoxic agents, immunotherapy, molecular targeted therapies or glucosteroids which are more frequently associated with PRES. Case presentation A 59-year old female, known with a relapse of her lung adenocarcinoma, had been treated with 4 cycles of cisplatin (75 mg/m2) and pemetrexed (500 mg/m2). Six weeks after this combination chemotherapy and within 28 h after the administration of pemetrexed maintenance therapy, she developed a generalised epileptic insult. Magnetic resonance imaging (MRI) of the brain showed bilateral areas of increased signal intensity in the subcortical parietal and frontal white matter. She was treated with a broad spectrum antiseizure drug, levetiracetam 750 mg twice daily and strict control of blood pressure. Discussion Diagnosis of PRES should be considered in all patients with neurologic symptoms who are at risk to develop PRES. It is crucial to establish the diagnosis as soon as possible since there is no specific treatment of PRES other than correction of the underlying risk factors and preventing seizure recurrence. Administration of pemetrexed is a possible risk factor for the development of PRES. PMID- 29173115 TI - Nitroguanidine (NQ) (2016). AB - 1-Nitroguanine (NG), also known as picrate, guanidine nitro, and N' nitroguanidine, is used by the military as a propellant. Oral rodent LD50 data are generally >5000 mg/kg. NG is neither an eye nor a skin irritant, and it is not a skin sensitizer. NG is not genotoxic. No inhalation data are available; however, there are data from both 14- and 90-day oral (feed) toxicity studies in male and female Sprague Dawley rats at dosages up to 1000 mg/kg/day. There were no deaths on these studies and the only effect considered possibly related to treatment was decreased weight in females at the high-dose level in the 90-day study. Mice at similar dosages were even less affected. The NOAEL for both rats and mice (oral) was 316 mg/kg/day. There was no evidence of developmental toxicity in Sprague-Dawley rats administered NG by oral gavage, and the free standing NOAEL was 1000 mg/kg with material toxicity. In Wistar rats, there was high mortality (50%) at 500 mg/kg NG administered by oral gavage; there was decreased body weight, feed consumption, and notable clinical signs in the dams at this dose level. Fetal toxicity could not be determined in this group. NG demonstrated maternal toxicity at 1000 mg/kg in rabbits; however, there were no evident differences in the rate of fetal malformations across the test groups. A NOAEL of 316 mg/kg was identified for maternal and fetal toxicity in this study. In a two-generation study, it was concluded the NG did not cause reproductive or fertility effects at dosages up to 1000 mg/kg/day. Absorption was rapid, non-dose dependent, and resulted in an apparent volume of distribution (VD) of between 0.66 (IV) and 0.85-0.87 (oral) l/kg. Elimination was primarily through the urine as unchanged compound. Human experience with NG dates back 100 years; however, no actual studies on humans have been reported. Non-military uses include automotive airbags, anti-corrosive coatings, and pharmaceutical manufacturing. The point of departure for Workplace Environmental Exposure Level (WEEL) derivations was 316 mg/kg, and a WEEL of 7 mg/m3 as an 8-h time-weighted average (TWA) was recommended. PMID- 29173114 TI - A Diagnostic Approach for Rodent Progressive Cardiomyopathy and Like Lesions in Toxicology Studies up to 28 Days in the Sprague Dawley Rat (Part 1 of 2). AB - Spontaneous rodent progressive cardiomyopathy (PCM) in the Sprague Dawley rat may confound identification and/or interpretation of potential test article (TA) related cardiotoxicity. Pathologists apply diagnostic term(s) and thresholds for diagnosing and assigning severity grades for PCM and/or PCM-like (PCM/like) lesions consistently within a study, which is necessary to identify and interpret TA-related findings. Due to differences in training and/or experiences, diagnostic terms and thresholds may vary between pathologists. Harmonized terminology and thresholds across studies will generate better historical control data, will likely enhance interpretation of study data, and may further enhance our understanding of the spontaneous change. An assessment of the diagnostic approaches of a group of 37 pathologists identified an approach that is relatively easily applied; and if adopted, it could enhance diagnostic consistency across studies. This approach uses the single "slash" term "necrosis/inflammatory cell infiltrate (NICI)" as the diagnosis for the spectrum of lesions seen in younger rats, uses no threshold for diagnosis (e.g., diagnose all lesions clearly identifiable as PCM/like), and uses aggregate lesion size of approximately >=45% of the field of view (FOV) using a 10*/22 eyepiece and the 40* objective or approximately >=100% of the FOV using the 60* objective as the criterion separating minimal from mild severities. PMID- 29173116 TI - 3-Nitro-1,2,4-triazol-5-one (2014). AB - 3-Nitro-1,2,4-triazol-5-one (NTO) is a potential replacement for energetics in military munitions. It is a component of IMX-101, a munition designed to prevent unintentional detonation. This report summarizes the dermal, oral, and inhalation animal toxicity data, including the results of genotoxicity and limited reproductive and developmental studies. NTO has an acute LD50 in rats and mice of >5000 mg/kg, is a potential eye and skin irritant, but does not induce skin sensitization. Acute inhalation toxicity studies in rats were negative, but testicular hypoplasia was observed in a 14-day oral study in rats administered NTO at >500 mg/kg/day. Similar findings were noted in an oral 90-day study at dosages >315 mg/kg/day and in reproductive toxicity studies at >125 mg/kg/day. NTO did not cause any developmental defects. All genotoxicity studies were negative. ADME and pharmacokinetics data showed rapid uptake and elimination of NTO from both inhalation and oral intakes. Biotransformation by liver microsomes demonstrated two separate pathways, one aerobic and the other anaerobic. NTO is not considered an endocrine disruptor. There is very little human data regarding NTO or the IMX-101 mixtures. Using testicular changes in rats as the point of departure for deriving a Workplace Environmental Exposure Level (WEEL) for NTO, the resulting BMDL10 was 40 mg/kg/day, and the 8-hour time-weighted average was 2 mg/m2. PMID- 29173117 TI - Psychosocial risks of prescription drug misuse among U.S. racial/ethnic minorities: A systematic review. AB - Prescription drug misuse (PDM) is the leading cause of accidental death in the U.S. One in five Americans report at least one lifetime incident of PDM. PDM has been studied extensively, yet there is limited inclusion of racial/ethnic minorities due to purportedly lower rates of PDM. However, health disparate groups often face more detrimental consequences of substance abuse including behavioral, social, and medical/mental health (e.g., injury, HIV/AIDS, incarceration, educational attainment, and comorbidity). Failing to characterize risk factors for and consequences of PDM in racial/ethnic minorities may mask the disproportionate negative impact of this epidemic. This systematic review of three research indexes revealed 28 peer-reviewed studies published on PDM in racial/ethnic minority adults. Results indicated a high prevalence of PDM among veterans, bisexual and gay young adults, and substance abusers compared to the general population. Demographic correlates of PDM included younger age, male gender, less educated, unmarried, and those with health/emotional issues. Rates of PDM in demographically vulnerable populations suggest that broadening inclusiveness in PDM research, interventions, and clinical practice is imperative.

PMID- 29173119 TI - Contact area affects frequency-dependent responses to vibration in the peripheral vascular and sensorineural systems. AB - Repetitive exposure to hand-transmitted vibration is associated with development of peripheral vascular and sensorineural dysfunctions. These disorders and symptoms associated with it are referred to as hand-arm vibration syndrome (HAVS). Although the symptoms of the disorder have been well characterized, the etiology and contribution of various exposure factors to development of the dysfunctions are not well understood. Previous studies performed using a rat-tail model of vibration demonstrated that vascular and peripheral nervous system adverse effects of vibration are frequency-dependent, with vibration frequencies at or near the resonant frequency producing the most severe injury. However, in these investigations, the amplitude of the exposed tissue was greater than amplitude typically noted in human fingers. To determine how contact with vibrating source and amplitude of the biodynamic response of the tissue affects the risk of injury occurring, this study compared the influence of frequency using different levels of restraint to assess how maintaining contact of the tail with vibrating source affects the transmission of vibration. Data demonstrated that for the most part, increasing the contact of the tail with the platform by restraining it with additional straps resulted in an enhancement in transmission of vibration signal and elevation in factors associated with vascular and peripheral nerve injury. In addition, there were also frequency-dependent effects, with exposure at 250 Hz generating greater effects than vibration at 62.5 Hz. These observations are consistent with studies in humans demonstrating that greater contact and exposure to frequencies near the resonant frequency pose the highest risk for generating peripheral vascular and sensorineural dysfunction.

Grandmothers are considered ideal caregivers because of cultural expectations of intergenerational care, and because they have not been decimated by AIDS to the same extent as younger adults. However, these grandmothers, who currently carry the majority of the burden of care for AIDS orphans, are themselves aging and dying. I argue here that in Lesotho, the caregiving demanded of grandmothers late into their lives not only alters kin relations for the living but has increasingly made a "good" death unachievable for elderly caregivers. PMID- 29173122 TI - Are Study and Journal Characteristics Reliable Indicators of "Truth" in Imaging Research? AB - Purpose To evaluate whether journal-level variables (impact factor, cited half life, and Standards for Reporting of Diagnostic Accuracy Studies [STARD] endorsement) and study-level variables (citation rate, timing of publication, and order of publication) are associated with the distance between primary study results and summary estimates from meta-analyses. Materials and Methods MEDLINE was searched for meta-analyses of imaging diagnostic accuracy studies, published from January 2005 to April 2016. Data on journal-level and primary-study variables were extracted for each meta-analysis. Primary studies were dichotomized by variable as first versus subsequent publication, publication before versus after STARD introduction, STARD endorsement, or by median split. The mean absolute deviation of primary study estimates from the corresponding summary estimates for sensitivity and specificity was compared between groups. Means and confidence intervals were obtained by using bootstrap resampling; P values were calculated by using a t test. Results Ninety-eight meta-analyses summarizing 1458 primary studies met the inclusion criteria. There was substantial variability, but no significant differences, in deviations from the summary estimate between paired groups (P > .0041 in all comparisons). The largest difference found was in mean deviation for sensitivity, which was observed for publication timing, where studies published first on a topic demonstrated a mean deviation that was 2.5 percentage points smaller than subsequently published studies (P = .005). For journal-level factors, the greatest difference found (1.8 percentage points; P = .088) was in mean deviation for sensitivity in journals with impact factors above the median compared with those below the median. Conclusion Journal- and study-level variables considered important when evaluating diagnostic accuracy information to guide clinical decisions are not systematically associated with distance from the truth; critical appraisal of individual articles is recommended.

AB - CONTEXT: Proper nutrition is crucial for an athlete to optimize his or her performance for training and competition. Athletes should be able to meet their dietary needs through eating a wide variety of whole food sources. EVIDENCE ACQUISITION: PubMed was searched for relevant articles published from 1980 to 2016. STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 4. RESULTS: An athlete should have both daily and activity-specific goals for obtaining the fuel necessary for successful training. Depending on the timing of their season, athletes may be either trying to gain lean muscle mass, lose fat, or maintain their current weight. CONCLUSION: An athlete will have different macronutrient goals depending on sport, timing of exercise, and season status. There are no specific athletic micronutrient guidelines, but testing should be considered for athletes with deficiency or injury. Also, some athletes who eliminate certain whole food groups (eg, vegetarian) may need to supplement their diet to avoid deficiencies. PMID- 29173123 TI - Screening Digital Mammography Recall Rate: Does It Change with Digital Breast Tomosynthesis Experience? AB - Purpose To compare screening mammography recall rate, cancer detection rate (CDR), and positive predictive values (PPVs) for digital mammography before and after radiologist experience with digital breast tomosynthesis (DBT). Materials and Methods This retrospective study was approved by the institutional review board and compliant with HIPAA. The authors reviewed screening mammography audit data obtained from 2009 to 2014, during which 108 276 digital mammographic examinations were performed (50 062 before and 58 214 after experience with DBT). Recall rate, CDR, PPV of positive screening result (PPV1), PPV of biopsy recommendation (PPV2), and PPV of biopsies performed (PPV3) of digital mammography for six radiologists were compared before (2009-2011) and after (2012 2014) experience with DBT. Radiologists worked in both a community setting, in which only digital mammography was available, and in two tertiary breast imaging centers, where they interpreted DBT images starting in 2012. Data were examined by using generalized linear mixed modeling wherein observations were nested for each radiologist over time. P < .05 was considered indicative of a statistically significant difference; 95% confidence intervals (CIs) were calculated. Results The average recall rate was 6.8% (range, 3.6%-9.7%) before experience with DBT and 7.9% (range, 5.5%-9.5%) after (P = .0316). Before experience with DBT, the recall rate increased only 0.01% for each year from 2009 to 2011 (P = .9727). After experience with DBT, the recall rate increased 0.65% for each year from 2012 to 2014 (P < .0127). CDR increased from 2.5 per 1000 examinations (95% CI: 2.2, 2.9) to 3.5 per 1000 examinations (95% CI: 3.0, 4.0; P = .0203). PPV2 and PPV3 increased significantly after experience with DBT, from 26.9% (95% CI: 19.9%, 35.3%) to 36.1% (95% CI: 31.7%, 40.7%; P = .0212) for PPV2 and from 31.2% (95% CI: 24.0%, 39.3%) to 40.0% (95% CI: 35.5%, 44.6%; P = .0290) for PPV3. Conclusion Recall rate, CDR, PPV2, and PPV3 of digital mammography increased after radiologist experience with DBT. (c) RSNA, 2017. PMID- 29173126 TI - Racial bias in sport medical staff's perceptions of others' pain. AB - Unequal treatment based on race is well documented in higher education and healthcare settings. In the present work, we examine racial bias at the intersection of these domains: racial bias in pain-related perceptions among National Collegiate Athletic Association (NCAA) Division 1 sport medical staff. Using experimental vignettes about a student-athlete who injured his/her anterior cruciate ligament (ACL), we find, like prior work, that respondents perceived Black (vs. White) targets as having higher initial pain tolerance. Moreover, this bias was mediated by perceptions of social class. We extend prior work by showing racial bias was not evident on other outcome measures, including perception of recovery process pain, likelihood of over-reporting pain, and over-use of drugs to combat pain. This suggests stricter boundary conditions on bias in pain perceptions than had been previously recognized. PMID- 29173125 TI - Time-series analysis: variation of anti-acetylcholine receptor antibody titer in myasthenia gravis is related to incidence of Mycoplasma pneumoniae and influenza virus infections. AB - Objectives The exacerbating factors of myasthenia gravis (MG) are unknown. However, it has been speculated that infections may play a role in disease progression. Methods We calculated the adjusted anti-acetylcholine receptor antibody (Adj-AChR-Ab) titers (range, 0-1) in 58 MG patients between 2006 and 2012. We determined the relationship between Adj-AChR-Ab titer and infection incidence. Results A cross-correlation function (CCF) analysis of Adj-AChR-Ab titer and incidence of Mycoplasma pneumoniae (M. pneumoniae) (r = 0.449, P < 0.0001) and influenza virus (r = 0.411, P < 0.001) infections indicated significant correlations. MG with thymoma was highly correlated with M. pneumoniae infection (r = 0.798, P < 0.0001). The relative risk for Adj-AChR-Ab titer was 1.407 for M. pneumoniae (95% CI, 1.193-1.661 for an increase in one infected patient per monitoring point) and 1.158 for influenza (95% CI, 1.071 1.253 for 100 infected patients). Conclusion Variation of Adj-AChR-Ab titer is significantly influenced by the presence of M. pneumoniae and influenza virus infections.

AB - Pathogens transmitted by ticks are the leading cause of arthropod-associated human diseases in the United States and managing the risk of exposure to potentially infected ticks is of vital public health importance. A 3-year integrated tick management program to control blacklegged ticks, Ixodes scapularis, the primary vector for the pathogenic agents of Lyme disease, human anaplasmosis, and babesiosis, was implemented in the town of Redding in southwestern Connecticut beginning in 2013. Combinations of white-tailed deer, Odocoileus virginianus, reduction, area application of the entomopathogenic fungus Metarhizium anisopliae, and fipronil-based rodent bait boxes were evaluated for their ability to reduce nymphal I. scapularis over 3 years. Interference from local hunters prevented sufficient, sustained deer removal previously reported to negatively impact I. scapularis abundances (i.e., <5 deer/km2). The combination of fipronil-based bait boxes and broadcast application of M. anisopliae had the most impact of any treatment combination; questing nymphs were reduced 78-95% within each year and Borrelia burgdorferi-infected questing nymphal I. scapularis encounter potential was reduced by 66% as compared with no treatment in the third year of the study. A combination of the broadcast application of M. anisopliae and small rodent-targeted fipronil-based bait boxes is an effective low-toxicity integrated approach that significantly reduced encounters with B. burgdorferi-infected questing nymphal I. scapularis on individual properties. PMID- 29173128 TI - Cognitive conflict resolution during psychotherapy: Its impact on depressive symptoms and psychological distress. AB - OBJECTIVE: The aim of this study was to assess the resolution of cognitive conflicts (CCs) within a randomized controlled trial testing the differential efficacy of group cognitive behavioral therapy (CBT) plus an individually tailored intervention module focused on CCs vs. group plus individual CBT, and to determine whether CC resolution was related to improvement in symptoms and psychological distress. METHODS: The data come from 104 adults meeting criteria for major depressive disorder and/or dysthymia. Change in scores on the Beck Depression Inventory-II and Clinical Outcomes in Routine Evaluation-Outcome Measure was assessed at the end of treatment and at three-month follow-up. Outcomes were compared between those participants who resolved their CCs and those who maintained them using three-level multilevel growth models. RESULTS: CC resolution did not depend on treatment allocation. Participants who resolved their CCs acquired greater benefits with regards to reduction of depressive symptoms and psychological distress than those who maintained their conflicts. CONCLUSIONS: CC seems to be a relevant notion to take into consideration to understand symptom improvement. Further research on CC might lead to the advancement of treatments which involve conflict resolution as a change mechanism. PMID- 29173129 TI - Preparation and performance of manganese-oxide-coated zeolite for the removal of manganese-contamination in groundwater. AB - A promising and easily prepared catalytic filler media, manganese-oxide-coated zeolite (MOCZ), for the removal of Mn (II) contamination in groundwater was studied. The optimal condition for MOCZ preparation was given as follows: acid activation of zeolite with 5% HCl mass percent for 12 h, then soaking of acid activated zeolite with 7% KMnO4 mass percent for 8 h, and finally calcination at 300 degrees C for 5 h. Acid activation significantly enlarged the specific surface area of the zeolite (>79 m2 g-1), subsequently enhancing the coating of manganese oxides onto the surface of the zeolite. This was further supported by the manganese-to-zeolite ratio (gammaMn) and Energy dispersive analysis-mapping. The gammaMn was over 12.26 mg Mn g-1 zeolite, representing more active sites for the adsorption and catalytic-oxidation of Mn (II). As such, great performance of Mn (II) removal by MOCZ was obtained in the filter experiment. An estimated 98 100% removal efficiency of Mn (II) was achieved in a greatly short startup time (only 2 h). During the filtration process, newborn flocculent manganese oxides with a mixed-valence of manganese (Mn (II) and Mn (IV)) were generated on the MOCZ surface, further facilitating the adsorption and catalytic-oxidation of Mn (II). The filter with MOCZ as adsorbent had a great performance on the Mn (II) removal in a wide range of hydraulic retention time (HRT) (4-40 min), particularly in a short HRT. Besides, the filter prolonged the filtration period (60 days), which would significantly reduce the frequency of backwash. Thus, it could be concluded that MOCZ prepared in this study showed a good performance in terms of Mn (II) removal in waterworks, especially small waterworks in the villages/towns.

AB - This analysis integrates poststructuralist and symbolic interactionist approaches to the self by incorporating the insights of science and technology studies regarding categorization processes. While the advent of the Internet has freed many individuals from geographical constraints on community formation, the architectures of online platforms produce a technological imperative to name aspects of the self with words. Using sexual identity hashtags on Instagram (e.g., #lesbian) thus performs paradoxical functions: the hashtag both enables the construction of a sexual identity within an affirming community and also reinforces the power relations that compel individuals to name and account for their sexual selves. By illustrating one way sexual identities function in the online lives of young women, this research complicates other scholars' findings that the salience of sexual identity categories is decreasing. PMID- 29173133 TI - The detection of Entamoeba histolytica and Toxoplasma gondii in wastewater. AB - To increase current knowledge on the epidemiology of protozoan parasites in wastewater treatment plants (WWTP), the occurrence of Entamoeba histolytica and Toxoplasma gondii in raw and treated wastewater was investigated. Samples were collected from WWTP twice a month over a period of 8 months. Determination of protozoa was performed using polymerase chain reaction (PCR) and light microscopy. After concentration and purification of wastewater samples, DNA extraction was conducted followed by PCR amplification of small subunit ribosomal RNA (SSU rRNA) gene sequences of E. histolytica and B1 gene of T. gondii. Loop Mediated Isothermal Amplification (LAMP) primer set was designed from E. histolytica hemolysin gene HLY6. Amplification of DNA in the LAMP mixture was monitored by naked eye as a blue color solution after addition of, hydroxynaphthol blue (HNB) to the reaction tube. Light microscopy revealed the presence of Entamoeba in all raw wastewater samples and treated water samples. PCR amplification of DNA products revealed that all, (9/9) wastewater samples were positive for Entamoeba. None was positive for Toxoplasma. These findings, which corroborate recent observations, indicate that E. histolytica may pose a public health risk. PMID- 29173135 TI - A 64-year-old woman with interstitial lung disease and positive antibodies against aminoacyl-transfer RNA synthetases in the absence of myositis: presentation of an anti-PL-12 positive antisynthetase syndrome. AB - Introduction The antisynthetase syndrome is a rare autoimmune disease described by the presence of inflammatory myositis, interstitial lung disease and antibodies against aminoacyl-transfer RNA synthetases. Interstitial lung disease can be the only manifestation in the absence of an inflammatory myositis. Other clinical signs are Raynaud phenomenon, hyperkeratotic skin lesions, fever and inflammatory polyarthritis. Case presentation We report the case of a 64-year old woman who complained of a dry cough, progressive dyspnea and arthralgia since 2 years, with no other systemic symptoms. High resolution computed tomography (HRCT) of the thorax showed the presence of bilateral ground glass opacities, reticular opacities and some traction bronchiectasis. Further biochemical testing revealed the presence of anti-PL12 antibodies. Management The diagnosis of antisynthetase syndrome was made and the patient was treated with steroids and azathioprine with a good response. Conclusion The search for antisynthetase antibodies should always be considered in patients with an interstitial lung disease without any other clinical symptoms or signs of an underlying connective tissue disease. PMID- 29173134 TI - An age-structured within-host HIV-1 infection model with virus-to-cell and cell to-cell transmissions. AB - In this paper, a within-host HIV-1 infection model with virus-to-cell and direct cell-to-cell transmission and explicit age-since-infection structure for infected cells is investigated. It is shown that the model demonstrates a global threshold dynamics, fully described by the basic reproduction number. By analysing the corresponding characteristic equations, the local stability of an infection-free steady state and a chronic-infection steady state of the model is established. By using the persistence theory in infinite dimensional system, the uniform persistence of the system is established when the basic reproduction number is greater than unity. By means of suitable Lyapunov functionals and LaSalle's invariance principle, it is shown that if the basic reproduction number is less than unity, the infection-free steady state is globally asymptotically stable; if the basic reproduction number is greater than unity, the chronic-infection steady state is globally asymptotically stable. Numerical simulations are carried out to illustrate the feasibility of the theoretical results. PMID- 29173136 TI - Studies on Foam Decay Trend and Influence of Temperature Jump on Foam Stability in Sclerotherapy. AB - OBJECTIVES: This study investigated the influence of temperature jump and liquid gas ratio on foam stability to derive the foam-decay law. METHODS: The experimental group conditions were as follows: mutation temperatures (10 degrees C, 16 degrees C, 20 degrees C, 23 degrees C, 25 degrees C, and 27 degrees C to >37 degrees C) and liquid-gas ratios (1:1, 1:2, 1:3, and 1:4). The control group conditions were as follows: temperatures (10 degrees C, 16 degrees C, 20 degrees C, 23 degrees C, 25 degrees C and 27 degrees C) and liquid-gas ratios (1:1, 1:2, 1:3, and 1:4). A homemade device manufactured using the Tessari DSS method was used to prepare the foam. The decay process was videotape recorded. In the drainage rate curve, the temperature rose, and the liquid-gas ratio varied from 1:1 to 1:4, causing faster decay. RESULTS: In the entire process, the foam volume decreased with increasing drainage rate. The relationships were almost linear. Comparison of the experimental and control groups shows that the temperature jump results in a drainage time range of 1 to 15 seconds. The half-life ranges from 10 to 30 seconds. The maximum rate is 18.85%. Changes in the preparation temperature yields a drainage time range of 3 to 30 seconds. The half-life varies from 20 to 60 seconds. CONCLUSION: Decreasing the temperature jump range and liquid-gas ratio gradually enhances the foam stability. The foam decay time and drainage rate exhibit an exponential function distribution. PMID- 29173137 TI - Testing Hypotheses About Social Targets. AB - The information search process is a critical cognitive activity in many domains, such as in legal investigations and criminal judgments. Previous research focused on leading strategies, in particular on the use of open and matching questions. The present research aimed to explore the use of asymmetric questions, namely dichotomous queries for which the "yes" and "no" answers are not equally diagnostic, during social hypothesis testing. In Study 1 (N = 253) participants were asked to select questions to assess a social target on some moral and nonmoral attributes. Explicit instructions to avoid asymmetric strategies were introduced. In Study 2 (N = 98) participants were asked to play the role of a judge who is supposed to be impartial. Results showed that, although people spontaneously use asymmetric yes-no format questions during the information search on moral traits, in certain conditions the use of such strategies could be monitored. Practical implications of these findings are discussed. PMID- 29173138 TI - Are Emotions Abstract or Concrete? AB - The ability to identify and communicate emotions is essential to psychological well-being. Yet research focusing exclusively on emotion concepts has been limited. This study examined nouns that represent emotions (e.g., pleasure, guilt) in comparison to nouns that represent abstract (e.g., wisdom, failure) and concrete entities (e.g., flower, coffin). Twenty-five healthy participants completed a lexical decision task. Event-related potential (ERP) data showed that emotion nouns elicited less pronounced N400 than both abstract and concrete nouns. Further, N400 amplitude differences between emotion and concrete nouns were evident in both hemispheres, whereas the differences between emotion and abstract nouns had a left-lateralized distribution. These findings suggest representational distinctions, possibly in both verbal and imagery systems, between emotion concepts versus other concepts, implications of which for theories of affect representations and for research on affect disorders merit further investigation. PMID- 29173139 TI - Walking Back to the Future. AB - Embodied cognition frameworks suggest a direct link between sensorimotor experience and cognitive representations of concepts ( Shapiro, 2011 ). We examined whether this holds also true for concepts that cannot be directly perceived with the sensorimotor system (i.e., temporal concepts). To test this, participants learned object-space (Exp. 1) or object-time (Exp. 2) associations. Afterwards, participants were asked to assign the objects to their location in space/time meanwhile they walked backward, forward, or stood on a treadmill. We hypothesized that walking backward should facilitate the online processing of "behind"/"past"-related stimuli, but hinder the processing of "ahead"/"future" related stimuli, and a reversed effect for forward walking. Indeed, "ahead"- and "future"-related stimuli were processed slower during backward walking. During forward walking and standing, stimuli were processed equally fast. The results provide partial evidence for the activation of specific spatial and temporal concepts by whole-body movements and are discussed in the context of movement familiarity. PMID- 29173140 TI - The Mere Exposure Instruction Effect. AB - The mere exposure effect refers to the well-established finding that people evaluate a stimulus more positively after repeated exposure to that stimulus. We investigated whether a change in stimulus evaluation can occur also when participants are not repeatedly exposed to a stimulus, but are merely instructed that one stimulus will occur frequently and another stimulus will occur infrequently. We report seven experiments showing that (1) mere exposure instructions influence implicit stimulus evaluations as measured with an Implicit Association Test (IAT), personalized Implicit Association Test (pIAT), or Affect Misattribution Procedure (AMP), but not with an Evaluative Priming Task (EPT), (2) mere exposure instructions influence explicit evaluations, and (3) the instruction effect depends on participants' memory of which stimulus will be presented more frequently. We discuss how these findings inform us about the boundary conditions of mere exposure instruction effects, as well as the mental processes that underlie mere exposure and mere exposure instruction effects. PMID- 29173141 TI - Too Tasty to Be Ignored. AB - Recent research has shown that even non-salient stimuli (colored circles) can gain attentional weight, when they have been loaded with some value through previous reward learning. The present study examined such value-based attentional weighting with intrinsically rewarding food stimuli. Different snacks were assumed to have different values for people due to individual food preferences. Participants indicated their preferences toward various snacks and then performed a flanker task with these snacks: they had to categorize a target snack as either sweet or salty; irrelevant flanker snacks were either compatible or incompatible with the target category. Results of a linear mixed-effects model show that the effect of flanker compatibility on participants' performance (response times) increased with the participants' preference toward the flanking snacks. This shows, for the first time, that attentional weightings in a flanker task with naturalistic stimuli (snacks) are modulated by participants' preferences toward the flankers. PMID- 29173142 TI - Sequence analysis of the N-acetyltransferase 2 gene (NAT2) among Jordanian volunteers. AB - The present study aimed to identify the NAT2 haplotypes, linkage disequilibrium, and novel NAT2 genetic variants among Jordanian population. We isolated the genomic DNA from 68 healthy, Arab, unrelated Jordanian volunteers to amplify the protein-coding region of NAT2 gene by polymerase chain reaction (PCR). Then, the amplified PCR products were sequenced using Applied Biosystems Model (ABI3730x1). It is found that the allele frequencies of known NAT2 genetic variants 191G>A, 282C>T, 341T>C, 481C>T, 590G>A, and 803A>G were 0.7, 26.5, 48.5, 35.3, 30.9, and 32.4%, respectively. The NAT2 allele frequencies were generally similar to those of white Europeans but different from those of Asian and African populations. The most common NAT2 haplotype was NAT2*5B with a frequency of 29.3%. According to the NAT2 haplotype frequencies, 72% (95% confidence interval 61.4-82.7%) of the volunteers were slow encoding NAT2 haplotype acetylators. The NAT2*5 represented variants 341T>C and 481C>T were in strong but not complete linkage disequilibrium (D' = 0.8, r2 = 0.63). In addition, this study found a novel nonsynonymous NAT2 436G>A genetic variant with low frequency (0.7%). However, this novel variant was predicted to be tolerated and not harmful to the NAT2 protein, using in silico prediction tools. It is concluded that the frequency of slow encoding NAT2 haplotype was high among Jordanian volunteers, which may have effects on drug responses and susceptibility to some diseases, such as cancers. PMID- 29173143 TI - The Role of Grb2 in Cancer and Peptides as Grb2 Antagonists. AB - BACKGROUND: Growth factor receptor-bound protein 2 (Grb2) is a 25 kDa adaptor protein, which was originally discovered to accomplish basic cellular events such as cell growth, cell proliferation, and metabolism. However, recent studies evidenced that Grb2 was largely involved in multiple tumor malignancies. The mature Grb2 is a 217 amino acid sequence, which consists of one Src homology 2 (SH2) domain flanked by two Src homology 3 (SH3) domains. Using these binding motives, the ubiquitously expressed Grb2 acts as an intermediate between cell surface activated receptors and downstream targets. OBJECTIVES: Consequently, the Grb2 becomes the key element of this oncogenesis and launched a number of defected signaling cascades. Therefore, vast concern of the Grb2 in multiple cancer patterns makes it an attractive therapeutic target. In this review, we have compiled the maximum tumor conformations caused by the involvement of the Grb2, the central role of Grb2 in numerous oncogenic pathways and particular approaches that can be useful to downregulate the Grb2 overexpression. We will discuss in details the activity of different types of novel peptides, their high affinity for the Grb2 protein and blockade of Grb2 mediated signaling pathways by targeting the SH2/SH3 binding sites. METHODS & RESULTS: There is a three-fold aspect to this review: Grb2 protein introduction, Grb2 protein involvement in cancer, and the role of peptides as Grb2 antagonists. First, Grb2 and compiled maximum tumor conformations induced by Grb2 involvement were introduced. Secondly, several oncogenic pathways of Grb2 involvement and particular approaches potentially useful to downregulate Grb2 overexpression were outlined. The activity of different types of novel peptides for the Grb2 protein was also detailed. Last but not least, the blockade of Grb2-mediated signaling pathways by targeting SH2/SH3 binding sites were summarized. CONCLUSION: We have epitomized the utmost cancer malignancies caused by abnormal signaling of the Grb2 adaptor molecule. Indeed, Grb2's enormous involvement in the progression and development of different cancers broaden our tactics to build anticancer drug candidates. Depending on the high affinity and increased specificity we have described the major potent peptides which may efficiently target and block the SH2 or SH3 arms of the Grb2. It may be of benefit for developing novel anticancer peptides. However, further work is needed to pinpoint more binding motives of Grb2 to generate efficacious anticancer agents for diverse human cancers in the near future.

AB - Since its discovery in 1983, followed by gene cloning in 1999, the histamine H3 receptor served as an outstanding target for drug discovery. The wide spectrum of possible therapeutic implications makes H3R's one of the most researched areas in the vast GPCR ligands field - started from imidazole containing ligands, through various successful imidazole replacements, with recent introduction of Wakix(r) to pharmaceutical market. One such replacement is piperazine moiety, a significant versatile scaffold in rational drug design for most of the GPCR ligands. Therefore, herein, we review ligands built on piperazine, as well as its seven membered analogue azepine, that target H3R's and their potential therapeutical applications, in order to elucidate the current state of the art in this vast field. Due to a high level of structural divergence among compounds described herein, we decided to divide them into groups, where the key division element was the position of nitrogen basicity decreasing moieties in (homo)piperazine ring. Paying attention to a number of published structures and their overall high biological activity, one can realize that the (homo)piperazine scaffold bids a versatile template also for histamine H3 receptor ligands. With two possible substitution sites and therefore a number of possible structural combinations, piperazine derivatives stand as one of the largest group of high importance among H3R ligands. PMID- 29173146 TI - Recent Advances in Peptide-Based Approaches for Cancer Treatment. AB - Peptide-based pharmaceuticals have recently experienced a renaissance due to their ability to fill the gap between the two main classes of available drugs, small molecules and biologics. Peptides combine the high potency and selectivity typical of large proteins with some of the characteristic advantages of small molecules such as synthetic accessibility, stability and the potential of oral bioavailability. One of the applications in which peptide-based approaches have grown rapidly is cancer therapy, with a focus on new and established targets. Many novel peptide-based methods for cancer treatment have been developed in the last few years, ranging from naturally-occurring and modified peptides to peptide drug conjugates, peptide nanomaterials and peptide-based vaccines. This review focuses on recent advances, advantages and challenges of these selected peptide based approaches for cancer treatment.

AB - BACKGROUND: From the past decade to date, several studies related to O-(2- [18F]fluoroethyl)-L-tyrosine (18F-FET) positron emission tomography (PET) in brain tumours have been published in the literature. OBJECTIVE: The aim of this narrative review is to summarize the recent developments and the current role of 18F-FET PET in brain tumours according to recent literature data. METHODS: Main findings from selected recently published and relevant articles on the role of 18F-FET PET in neuro-oncology are described. RESULTS: 18F-FET PET may be useful in the differential diagnosis between brain tumours and non-neoplastic lesions and between low-grade and high-grade gliomas. Integration of 18F-FET PET into surgical planning allows better delineation of the extent of resection beyond margins visible with standard MRI. For biopsy planning, 18F-FET PET is particularly useful in identifying malignant foci within non-contrast-enhancing gliomas. 18F-FET PET may improve the radiation therapy planning in patients with gliomas. This metabolic imaging method may be useful to evaluate treatment response in patients with gliomas and it improves the differential diagnosis between brain tumours recurrence and posttreatment changes. 18F-FET PET may provide useful prognostic information in high-grade gliomas. CONCLUSION: Based on recent literature data 18F-FET PET may provide additional diagnostic information compared to standard MRI in neuro-oncology.

AB - The main function of proteases in any living organism is the cleavage of proteins resulting in the degradation of damaged, misfolded and potentially harmful proteins and therefore providing the cell with amino acids essential for the synthesis of new proteins. Besides this main function, proteases may play an important role as signal molecules and participate in numerous protein cascades to maintain the vital processes of an organism. Plant proteases are no exception to this rule. Moreover, in contrast to human-encoded enzymes, many plant proteases possess exceptional features such as higher stability, unique substrate specificity and a wide pH range for enzymatic activity. These valuable features make plant-derived proteolytic enzymes suitable for many biomedical applications, and furthermore, the plants can serve as factories for protein production. Plant proteases are already applied in the treatment of several pathological conditions in the human organism. Some of the enzymes possess antitumour, antibacterial and antifungal activity. The collagenolytic activity of plant proteases determines important medical applications such as the healing of wounds and burn debridement. Plant proteases may affect blood coagulation processes and can be applied in the treatment of digestive disorders. The present review summarizes recent advances and possible applications for plant proteases in biomedicine, and proposes the further development of plant-derived proteolytic enzymes in the biotechnology and pharmaceutical industries.

AB - BACKGROUND: Topical drug administration offers an attractive route with minimal invasiveness. It also avoids limitations of intravenous administration such as the first pass metabolism and presystemic elimination within the gastrointestinal tract. Furthermore, topical drug administration is safe, have few side effects, is easy to apply, and offers a fast onset of action. However, the development of effective topical formulations still represents a challenge for the desired effect to be reached, locally or systemically. Solid lipid nanoparticles and nanostructured lipid carriers are particular candidates to overcome the problem of topical drug administration. The nanometric particle size of lipid nanoparticles favors the physical adhesion to the skin or mucosal, what can also be attained with the formation of hybrid (nanoparticles/polymer) systems. METHODS: In this review, we discuss the major challenges for lipid nanoparticles formulations for topical application to oral mucosa, skin, and eye, highlighting the strategies to improve the performance of lipid nanoparticles for topical applications. Next, we critically analyzed the in vitro and in vivo approaches used to evaluate lipid nanoparticles performance and toxicity. CONCLUSION: We addressed some major drawbacks related to lipid nanoparticle topical formulations and concluded the key points that have to be overcome to help them to reach the market in topical formulations to oral mucosa, skin and eye. PMID- 29173150 TI - An Update of Patents, Preclinical and Clinical Outcomes of Lipid Nanoparticulate Systems. AB - BACKGROUND: Lipid nanoparticles have attracted increased degree of scientific and commercial attention in the last decade.

The large number of patents and preclinical trials in the recent years suggests that these systems will find immense potential in near future. PMID- 29173151 TI - Lipid Based Nanoparticles as Inherent Reversing Agents of Multidrug Resistance in Cancer. AB - BACKGROUND: Multidrug resistance in cancer is the ability of a cancer cell to resist treatment with a wide range of structurally and functionally dissimilar chemotherapeutics. The resistant phenotype could arise in response to several cellular changes that ultimately result in a decrease in intracellular drug accumulation (or effectiveness), either by limiting cellular drug entry, or by expulsion of those molecules that have made it into the cell. Both blocking drug cellular entry and its expulsion are mostly brought about by the cell membrane. Several pharmaceutical excipients (mainly lipids, surfactants and amphililc copolymers) have been reported to reverse multidrug resistance by addressing cell membrane related changes resulting in low intracellular drug levels in resistant cells. These excipients are routinely used in the preparation of lipid based nanoparticles endowing inherent multidrug resistance reversing properties to these nanoparticles. METHODS: In this review, cell membrane alterations resulting in multidrug resistance will be initially reviewed, followed by a discussion of the different types of lipid NPs and the potential held by the excipients used in their preparation in multidrug resistance reversal. Finally, a discussion on how lipid nanoparticles have been engineered and used in different occasions to enable multidrug resistance reversal is included. CONCLUSION: The superior role held by lipid nanoparticles in comparison to free excipients will be highlighted. PMID- 29173152 TI - Lipid-based Nanosized Delivery Systems for Fluoroquinolones: a Review. AB - BACKGROUND: The class of fluoroquinolone antibiotics, due to its core chemical modifications, is considered as wide-spectrum antibacterial drugs with useful pharmacokinetic and pharmacodynamic properties. However, because of their poor solubility in water, they are used as salts (lactates or hydrochlorides). Fluoroquinolones, bacterial membranes and eukaryotic cell membranes interactions are well known and their permeation properties are well investigated. In fact, they are concentrated inside the cells and intracellular compartments. Nanotechnology in Drug Delivery has developed many supra-molecular structures that have been used to improve both pharmacokinetic and pharmacodynamic properties. The main results of the published papers showed reduction of toxicity, higher intracellular concentrations (both bacteria and eukaryotic), enhancement of antimicrobial activity, prolonged drug release, decreased mortality in animal model studies, improved water solubility and improved in vitro efficacy against intracellular pathogens. METHODS: a literature search was performed in the NCBI-PUBMED database, with no time range, using the keywords "solid lipid nanoparticles" and 'quinolones' or the name of single antibiotics. RESULTS: the most important aspects of lipid-based nanocarrier technology used for fluoroquinolones have been highlighted, with a focus on the latest formulation developments that have led to significant improvements of pharmacokinetics and pharmacodynamics. Both technological and microbiological aspects of published papers have been discussed. CONCLUSION: the potentiality of using lipid nanoparticles to improve the efficacy and potency of quinolone antibiotics has been supported by recent scientific publications, although some criticism appeared due to the microbiological investigative methods used and because of lack of systematic evaluation about the influence of technological approaches to the in vitro and in vivo drug activity. PMID- 29173153 TI - Therapeutic potential of drug delivery by means of lipid nanoparticles: reality or illusion? AB - BACKGROUND: Solid lipid nanoparticles (SLN) are colloidal drug carrier systems that contribute several properties required from a sophisticated drug delivery system for increasing drug bioavailability and providing effective therapy. Many advantages of SLN have been reported over traditional dosage forms and their colloidal counterparts in the studies since the early 1990s. They were optimized for oral drug delivery for the first time. The first SLN formulations were produced by reducing the particle size of solid lipid microparticles by spray congealing technique in the late 1980s. Then, studies have been continued investigating for their different administration routes else including parenteral, transdermal, ocular, nasal, respiratory etc. METHODS: Their foremost qualifications such as their biocompatible nature and high drug entrapment efficiency make them promising colloidal drug carrier systems for the effective treatment of serious disasters like genetic disorders and cancer. CONCLUSION: In this review, therapeutic potential of drug delivery of SLN and nanostructured lipid carriers (NLC, the second generation of SLN) are summarized considering researches and patents on their administration via different routes and their preparations in the pharmaceutical market. PMID- 29173154 TI - Effective Delivery Routes And Strategies For Solid Lipid Nanoparticles (Sln) And Nanostructured Lipid Carriers (Nlc). AB - BACKGROUND: SLNs and NLCs have remarkably wide range of properties which make them useful for several potential applications in drug delivery, clinical medicine, and research, as well as in parenteral, dermal, pulmonary and topical delivery of drugs. The unique size-dependent properties of the solid lipid nanoparticles make them at the forefront of the rapidly developing field of nanotechnology offering development of new therapeutics having reduced toxic side effects and increased treatment efficacy. METHODS: SLNs and NLCs are very attractive drug delivery candidates, primarily due to their relatively stable constituents and probable ease of drug encapsulations. The incorporation of drugs into nanocarriers like SLNs and NLCs for several levels of drug targeting offers good potential in gene transfer, cosmetic and food industry with great promise for reaching the goal of controlled and site-specific drug delivery. Lipid nanoparticle drug delivery technology presents considerable opportunities for improving medical therapeutics, but the technology's potential remains unrealized. RESULTS: The review has focused on the various effective delivery routes and strategies for SLNs and NLCs, and their applicability in the encapsulation of therapeutics. Number of research works has been successfully carried out in this area. It would result in a simultaneous improvement in the quality, efficacy, and safety profile of drugs. CONCLUSION: However, because of mentioned limitations and difficulties related to them, the total number of products on the market is still limited. Although the concept of PEGylation to increase half-life of nanoparticles revolutionized the nanoparticle-mediated drug delivery field, significant improvements are warranted in this area. PMID- 29173155 TI - Imaging of Bacteria: Is there Any Hope for the Future Based on Past Experience? AB - Infectious diseases remain a major health problem and cause of death worldwide. It is expected that the socio-economic impact will further intensify due to escalating resistance to antibiotics, an ageing population and an increase in the number of patients under immunosuppressive therapy and implanted medical devices. Even though radiolabeled probes and leukocytes are routinely used in clinical practice, it might still be difficult to distinguish sterile inflammation from inflammation caused by bacteria. Moreover, the majority of these probes are based on the attraction of leukocytes which may be hampered in neutropenic patients. Novel approaches that can be implemented in clinical practice and allow for swift diagnosis of infection by targeting the microorganism directly, are posing an attractive strategy. Here we review the current strategies to directly image bacteria using radionuclides and we provide an overview of the preclinical efforts to develop and validate new approaches. Indeed, significant progress has been made in the past years, but very few radiopharmaceuticals (that were promising in preclinical studies) have made it into clinical practice. We will discuss the challenges that remain to select good candidates for imaging agents targeting bacteria. PMID- 29173156 TI - Identification of Human Acetylcholinesterase Inhibitors from the Constituents of EGb761 by Modeling Docking and Molecular Dynamics Simulations. AB - AIM AND OBJECTIVE: EGb761, a standardized and well-defined product extract of Ginkgo biloba leaves, has beneficial role in the treatment of multiple diseases, particularly Alzheimer's disease (AD). Identification of natural acetylcholinesterase (AChE) inhibitors from EGb761 would provide a novel therapeutic approach against the Alzheimer's disease. MATERIAL AND METHOD: A series of 21 kinds of promising EGb761 compounds were selected, and subsequently evaluated for their potential ability to bind AChE enzyme by molecular docking and a deep analysis of protein surface pocket features. RESULTS: Docking results indicated that these compounds can bind tightly with the active site of human AChE, with favorable distinct interactions around several important residues Asp74, Leu289, Phe295, Ser293, Tyr341, Trp286 and Val294 in the active pocket. Most EGB761 compounds could form the hydrogen bond interactions with the negatively charged Asp74 and Phe295 residues. Among these compounds, diosmetin is the one with the best-predicted docking score while three key hydrogen bonds can be formed between small molecule and corresponding residues of the binding site. Besides, other three compounds luteolin, apigenin, and isorhamnetin have better predicted docking scores towards AChE than other serine proteases, i.e. Elastase, Tryptase, Factor XA, exhibiting specificity for AChE inhibition. The RMSD and MM GBSA results from molecular dymamic simulations indicated that the docking pose of diosmetin-AChE complex displayed highly stable, which can be used for validating the accuracy of molecular docking study. Subsequently, the AChE inhibitory activities of these compounds were evaluated by the Ellman's colorimetric method. CONCLUSION: The obtained results revealed that all the four compounds exhibited modest AChE inhibitory activity, among which Diosmetin manifested remarkable anti-AChE activity, comparable with the reference compound, Physostigmine. It can be deduced that these EGB761 compounds can be regarded as a promising starting point for developing AChE inhibitors against AD. PMID- 29173157 TI - In vitro Characterization of NPS Metabolites Produced by Human Liver Microsomes and the HepaRG Cell Line Using Liquid Chromatographyhigh Resolution Mass Spectrometry (LC-HRMS) Analysis: Application to Furanyl Fentanyl. AB - BACKGROUND: Identification of metabolites is of importance in the challenge of new psychoactive substances (NPS) as it could improve the detection window in biological matrices in clinical and forensic cases of intoxication. Considering the numerous and diverse NPS reported each year, producers increasingly appear today to be targeting non-controlled synthetic opioids, involving fentanyl derivatives such as furanyl fentanyl (Fu-F). OBJECTIVE: This work aims to investigate and compare metabolites of Fu-F using two in vitro experimental approaches. METHODS: CYP- and UGT-dependent metabolites of Fu-F were investigated by means of analyses of both human liver microsome (HLM) and hepatic (HepaRG) cell line incubates using liquid chromatography with high-resolution mass detection and, subsequently, compared and confronted to recently published data. RESULTS: Seventeen Fu-F metabolites were produced and several metabolic pathways can be postulated. HLMs and HepaRG cultures appear to be complementary: HepaRG cells produced 9 additional metabolites, but which appear to be minor in vivo metabolites. Specific* and/or abundant Fu-F metabolites are dihydrodiol-Fu-F*, norFu-F* and despropionylfentanyl. However, norFu-F seems to be inconstantly observed in in vivo cases. Furthermore, a sulfate metabolite presents at significant rate in urine obtained from FU-F users was not identified here, as in another in vitro study. CONCLUSION: HLMs represent an acceptable first choice tool for a single NPS metabolism study in forensic laboratories. Dihydrodiol-Fu-F and despropionylfentanyl could be proposed as reliable metabolites to be recorded in HRMS libraries in order to improve detection of Fu-F users. Nevertheless, additional verifications of in vivo data remain necessary to confirm relevant blood and urinary metabolites of Fu-F. PMID- 29173158 TI - Novel Insights into the Molecular Interaction of a Panduratin A Derivative with the Non Structural Protein (NS3) of Dengue Serotypes: A Molecular Dynamics Study. AB - BACKGROUND: The ligand PKP10 having substitution of Cl- at R2 and R3 positions of ring A of Panduratin A i.e., ((1R,2S,5S)-5-(2,3-dichlorophenyl)-3-methyl-2-(3 methylbut-2-nyl)cyclohex-3- enyl)(2,6-dihydroxy-4-methylphenyl)methanone hydrate) has been observed to block the Nuclear Receptor Binding Protein binding site of Non Structural protein 3 in all dengue serotypes. In continuation with our earlier study, we have reported sixty novel Panduratin A derivatives compounds where substitution was done in positions 2 and 3 position of the benzyl ring A of Panduratin A with various substituents. METHODS: We selected ((1R,2S,5S)-5-(2,3 dichlorophenyl)-3-methyl-2-(3-methylbut-2-nyl)cyclohex-3- nyl) (2,6-dihydroxy-4 methylphenyl) methanone hydrate) (PKP10) for molecular dynamics (MD) simulations as it constantly produced lowest CDocker interaction energy of among all the sixty five derivatives. The CDocker interaction energy was predicted to be 140.804, -79.807, -78.217 and -84.073 Kcalmol-1 respectively against NS3 protein of dengue serotypes (DENV1-4). To understand the dynamics of the PKP10 with NS3 protein, each complex was subjected to molecular dynamics simulations of 50 ns in aqueous solution. MD (Molecular Dynamics) simulation study revealed that the binding of ligand PKP10 at the active site of NS3 induces a conformational change in all serotypes which was well supported by principal component analysis. RESULT: To the best of our knowledge, this is first ever study which provided atomistic insights into the interaction of PKP10 with NS3 protein of dengue serotypes. CONCLUSION: The result from our study along with in vitro studies is expected to open up better avenues to develop inhibitors for dengue virus in the near future. PMID- 29173159 TI - Antioxidant Potential and Wound Healing Activity of Biosurfactant Produced by Acinetobacter junii B6. AB - BACKGROUND: Recently, the development of a safe bioactive material with antioxidant properties, which can improve healing activity are focusing. Biosurfactants are very famous for their antimicrobial and free radical scavenging activities. Thereof, the main aim of the present study was to investigate the antioxidant and wound healing activity of the lipopeptide biosurfactant (LBS) produced by Acinetobacter junii B6. DPPH radical scavenging activities and FRAP assays were used to measure the antioxidant properties. METHODS: For evaluation of the wound healing activity, 36 rats (previously wounded in depilated thoracic region) were randomly distributed into six groups and chromatic, wound contraction, and histopathological feature were examined. The assessment levels of reactive oxygen species (ROS) after LBS exposure were determined using malondialdehyde (MDA), hydrogen peroxide (H2O2), and glutathione (GSH) assay kits. RESULTS: DPPH assay showed notable scavenging activities at the corresponding concentrations with IC50 value of 0.7 mg/ml. The reductive potency of the LBS showed lower performance at low concentration, while exhibited a remarkable increase at higher concentration. The best histopathological remission was achieved following treatment by 5 mg/ml of the LBS. Scar wounds at day 13 showed the lowest lesion sizes, increased re-epithelialization, hair follicle detection, and decreased amounts of neutrophilic inflammation, immaturity of the wound bed, erythema, edema, capillary, and retention of necrotic tissue. CONCLUSION: Results from MDA, H2O2, and GSH levels of the treated sample confirmed the scavenging property of the bacterial derived LBS through ROS. It could be concluded that the pharmaceutical formula encourages the wound healing because of its notable antioxidant capacity. HIGHLIGHTS: * DPPH and FRAP assays showed notable scavenging activity. * MDA, H2O2, and GSH; confirmed the scavenging property of the derived biosurfactant through ROS. * Synthesized formula encourages the healing of the wound because of its antioxidant capacity. PMID- 29173160 TI - Simple and Fast Gas-chromatography Mass Spectrometry Assay to Assess Delta 9 Tetrahydrocannabinol and Cannabidiol in Dogs Treated with Medical Cannabis for Canine Epilepsy. AB - BACKGROUND: To date, an increasing number of pet owners, especially in the USA, are using cannabis-derived products containing generally delta 9 tetrahydrocannabinol (THC) and cannabidiol (CBD) to help their animals' health. Unfortunately, studies on the clinical use of cannabinoids in veterinary medicine are still limited, and the application of analytical methodologies for the determination of cannabinoids in animal (especially dog) biological matrices such as plasma, is still missing. METHODS: A reliable, fast, accurate, simple gas chromatography-mass spectrometry (GC-MS) method was developed and validated for the quantification of THC and CBD in plasma samples of eight dogs under therapeutic treatment for epilepsy and receiving oral administration of medical cannabis (Bediol). RESULTS: The method was linear for both the analytes under investigation with coefficients of determination (r2) of at least 0.99. Absolute analytical recovery (mean +/- SD) ranged from 80.6 +/- 6.2% for THC and 81.7 +/- 4.3% for CBD. The matrix effect showed less than 10% analytical suppression due to endogenous substances for both the analytes. The intra-assay and inter-assay precision values ranged from 4.9% to 12.7%, and from 5.2% to 8.7% respectively. The intra-assay and inter-assay accuracy values ranged from 2.3% to 9.6% and from 3.4% to 13.0%, respectively. CONCLUSION: The validated method was successfully applied to real samples; moreover, to assess the potential of the method applicability and robustness in future veterinary clinical studies on cannabinoids therapy, we attempted to follow the kinetic of THC and CBD in the plasma of two dogs under therapy at different times after Bediol administration. PMID- 29173161 TI - Analytical Strategies to Disclose Repeated Consumption of New Psychoactive Substances by Hair Analysis. AB - BACKGROUND: New psychoactive substances (NPS) are a heterogenic group of substances with different chemical structures and psychotropic effects. METHOD: Many pharmacotoxicological laboratories performing drug testing in conventional and nonconventional biological matrices for clinical and forensic purposes do not include screening procedures for NPS in their routine protocols. This is mainly due to the continued entry in the market of newly synthesized products, the low availability of reference standards, in particular of their metabolites, the low availability of immunochemical kits, etc. Moreover, many of the new compounds are very potent, and low doses ingested will lead to low concentrations in biological matrices, especially in hair. RESULTS: Hair analysis has become a powerful tool for detecting chronic drug use and has become a routine technique in forensic toxicology laboratories. CONCLUSION: The aim of this study was to set up analytical strategies to identify repeated consumption of NPS by hair analysis. Although UHPLC-MS/MS may represent the elective technique in studying NPS, a combination of both GC-MS and UHPLC-MS/MS techniques is useful in creating a complete toxicological image. PMID- 29173163 TI - Tocopherol and Tocotrienol: Therapeutic Potential in Animal Models of Stress. AB - BACKGROUND: Scientific reports had shown that stress is related to numerous pathological changes in the body. These pathological changes can bring about numerous diseases and can significantly cause negative effects in an individual. These include gastric ulcer, liver pathology and neurobehavioral changes. A common pathogenesis in many diseases related to stress involves oxidative damage. Therefore, the administration of antioxidants such as vitamin E is a reasonable therapeutic approach. However, there is conflicting evidence about antioxidant supplementation. OBJECTIVE: The aim of this work was to summarize documented reports on the effects of tocopherol and tocotrienol on various pathological changes induced by stress. RESULTS AND CONCLUSION: This review will reveal the scientific evidence of enteral supplementation of vitamin E in the forms of tocotrienol and tocopherol in animal models of stress. These models mimic the stress endured by critically ill patients in a clinical setting and psychological stress in individuals. Positive outcomes from enteral feeding of vitamin E in reducing the occurrence of stress-induced pathological changes are discussed in this review. These positive findings include their ability to reduced stress induced gastric ulcers, elevated liver enzymes and improved locomotors activity. Evidences showing tocotrienol and tocopherol effects are not just related to its ability to reduce oxidative stress but also acting on other mechanism, are discussed. PMID- 29173162 TI - Oral Fluid vs. Urine Analysis to Monitor Synthetic Cannabinoids and Classic Drugs Recent Exposure. AB - BACKGROUND: Urine is a common biological sample to monitor recent drug exposure, and oral fluid is an alternative matrix of increasing interest in clinical and forensic toxicology. Limited data are available about oral fluid vs. urine drug disposition, especially for synthetic cannabinoids. OBJECTIVE: To compare urine and oral fluid as biological matrices to monitor recent drug exposure among HIV infected homeless individuals. METHODS: Seventy matched urine and oral fluid samples were collected from 13 participants. Cannabis, amphetamines, benzodiazepines, cocaine and opiates were analyzed in urine by the enzyme multipliedimmunoassay- technique and in oral fluid by liquid chromatography tandem mass spectrometry (LCMSMS). Eleven synthetic cannabinoids were analyzed in urine and in oral fluid by LC-MSMS. RESULTS: Five oral fluid samples were positive for AB-FUBINACA. In urine, 4 samples tested positive for synthetic cannabinoids PB-22, 5-Fluoro-PB-22, AB-FUBINACA, and metabolites UR-144 5 pentanoic acid and UR-144 4-hydroxypentyl. In only one case, oral fluid and urine results matched, both specimens being AB-FUBINACA positive. For cannabis, 40 samples tested positive in urine and 30 in oral fluid (85.7% match). For cocaine, 37 urine and 52 oral fluid samples were positive (75.7% match). Twenty-four urine samples were positive for opiates, and 25 in oral fluid (81.4% match). For benzodiazepines, 23 samples were positive in urine and 25 in oral fluid (85.7% match). CONCLUSION/DISCUSSION: These results offer new information about drugs disposition between urine and oral fluid. Oral fluid is a good alternative matrix to urine for monitoring cannabis, cocaine, opiates and benzodiazepines recent use; however, synthetic cannabinoids showed mixed results. PMID- 29173164 TI - Epigenetic Mechanisms: Role in Hematopoietic Stem Cell Lineage Commitment and Differentiation. AB - Major breakthroughs in the last several decades have contributed to our knowledge of the genetic regulation in development. Although epigenetics is not a new concept, unfortunately, the role of epigenetics has not come to fruition in the past. But the field of epigenetics has exploded within the past decade. Now, growing evidences show a complex network of epigenetic regulation in development. The epigenetic makeup of a cell, tissue or individual is much more complex than their genetic complement. Epigenetic modifications are more important for normal development by maintaining the gene expression pattern in tissue- and context specific manner. Deregulation of epigenetic mechanism can lead to altered gene expression and its function, which result in altered tissue specific function of cells and malignant transformation. Epigenetic modifications directly shape Hematopoietic Stem Cell (HSC) developmental cascades, including their maintenance of self-renewal and multilineage potential, lineage commitment, and aging. Hence, there is a growing admiration for epigenetic players and their regulatory function in haematopoiesis. Epigenetic mechanisms underlying these modifications in mammalian genome are still not completely understood. This review mainly explains 3 key epigenetics mechanisms including DNA methylation, histone modifications and non-coding RNAs inference in hematopoietic lineage commitment and differentiation. PMID- 29173165 TI - Exploring Promising Immunomodulatory Potential of Natural and Synthetic 1,3 Diphenyl-2-propen-1-one Analogs: A Review of Mechanistic Insight. AB - The immune system is an intricate and coordinated nexus serving as a natural defense to preclude internal and external pathogenic insults. The deregulation in the natural balance of immunological functions as a consequence of either over expression or under expression of immune cells tends to cause disruption of homeostasis in the body and may lead to development of numerous immune system disorders. Chalcone moieties (1,3-diphenyl-2-propen-1-one) have been well documented as ideal lead compounds or precursors to design a wide range of pharmacologically active agents to down-regulate various immune disorders. Owing to their unique structural and molecular framework, these alpha, beta-unsaturated carbonyl-based moieties have also gained remarkable recognition due to their other multifarious pharmacological properties including antifungal, anti inflammatory, anti-malarial, antibacterial, anti-tuberculosis, and anticancer potential. Though a great number of methodologies are currently being employed for their synthesis, this review mainly focuses on the natural and synthetic chalcone derivatives that are exclusively synthesized via Claisen-Schmidt condensation reaction and their immunomodulatory prospects. We have critically reviewed the literature and provided convincing evidence for the promising efficacy of chalcone derivatives to modulate functioning of various innate and adaptive immune players including granulocytes, mast cells, monocytes, macrophages, platelets, dendritic cells, natural killer cells, and T-lymphocytes. PMID- 29173166 TI - Anticancer Potential of Thiazole Derivatives: A Retrospective Review. AB - This review brings forth the potential of thiazole derivatives for their anticancer activities. The emphasis is placed on the structural diversity of thiazole derivatives, responsible for their specific anticancer activity. Multiple classes of thiazole derivatives such as Schiff base, mono-, di-, tri-, and heterocyclic substituents that possess anticancer activity have been exemplified. Molecular modelling of compounds that predicts enhanced anticancer activity of the modified structures has also been elaborated in the review. Significant advancements in synthetic chemistry related to cytotoxicity can now better position the drug discovery team to undertake thiazoles as valuable leads. The beneficial thiazole derivatives possessing anticancer activity will reignite the interest of medicinal chemists in thiazole and their derivatives. PMID- 29173168 TI - CRISPR/Cas9 Editing to Facilitate and Expand Drug Discovery. AB - INTRODUCTION: The ability of most laboratories to easily access CRISPR/Cas9 engineering tools has caused a revolution in biology. One of the areas that will continue to be impacted by genome editing is the drug discovery process. OBJECTIVE: CRISPR/Cas9 will not only serve to accelerate the drug discovery pipeline, but also streamline line it by identifying high-value targets, facilitating the validation of drug: target interactions and mechanisms of action, and stimulating the development of phenotype-based high throughput screens as alternatives to target-based assays. CONCLUSION: We review the literature and hurdles that have been overcome to develop the current generation of tools being used to enrich the drug discovery paradigm. PMID- 29173167 TI - A Systematic Review on the Sinomenine Derivatives. AB - Sinomenine is one of the most widely known alkaloids owing to different therapeutic properties including anti-inflammatory and immunosuppressive activities, as well as the potency in neurodegenerative disorders, such as Alzheimer's disease and Parkinson's disease. Sinomenine has been studied as a potential anti-inflammatory agent through appropriate structural modifications. Recently, a number of such approaches have been attempted in various laboratories with great success. Several series of derivatives have been synthesized with changes at rings A, B, C and D. Herein, we present an up to date review of modifications and bioactivities of important modified derivatives. These studies offer interesting knowledge on the bioactivity and structural specificity of sinomenine, providing better understanding of the structure-activity relationships (SAR) between designing and development of sinomenine derivative with better therapeutic and lower side effects. PMID- 29173169 TI - CRISPR/Cas9 Gene Editing: From Basic Mechanisms to Improved Strategies for Enhanced Genome Engineering In Vivo. AB - INTRODUCTION: Targeted genome editing using the CRISPR/Cas9 technology is becoming a major area of research due to its high potential for the treatment of genetic diseases. Our understanding of this approach has expanded in recent years yet several new challenges have presented themselves as we explore the boundaries of this exciting new technology. Chief among these is improving the efficiency but also the preciseness of genome editing. The efficacy of CRISPR/Cas9 technology relies in part on the use of one of the major DNA repair pathways, Homologous recombination (HR), which is primarily active in S and G2 phases of the cell cycle. Problematically, the HR potential is highly variable from cell type to cell type and most of the cells of interest to be targeted in vivo for precise genome editing are in a quiescent state. CONCLUSION: In this review, we discuss the recent advancements in improving targeted CRISPR/Cas9 based genome editing and the promising ways of delivering this technology in vivo to the cells of interest. PMID- 29173171 TI - New Developments in CRISPR/Cas-based Functional Genomics and their Implications for Research Using Zebrafish. AB - INTRODUCTION: Genome editing using CRISPR/Cas9 has advanced very rapidly in its scope, versatility and ease of use. Zebrafish (Danio rerio) has been one of the vertebrate model species where CRISPR/Cas9 has been applied very extensively for many different purposes and with great success. In particular, disease modeling in zebrafish is useful for testing specific gene variants for pathogenicity in a preclinical setting. Here we describe multiple advances in diverse species and systems that can improve genome editing in zebrafish. OBJECTIVE: To achieve temporal and spatial precision of genome editing, many new technologies can be applied in zebrafish such as artificial transcription factors, drug-inducible or optogenetically-driven expression of Cas9, or chemically-inducible activation of Cas9. Moreover, chemically- or optogenetically- inducible reconstitution of dead Cas9 (catalytically inactive, dCas9) can enable spatiotemporal control of gene regulation. In addition to controlling where and when genome editing occurs, using oligonucleotides allows for the introduction (knock-in) of precise modifications of the genome. CONCLUSION: We review recent trends to improve the precision and efficiency of oligo-based point mutation knock-ins and discuss how these improvements can apply to work in zebrafish. Similarly to how chemical mutagenesis enabled the first genetic screens in zebrafish, multiplexed sgRNA libraries and Cas9 can enable the next revolutionary transition in how genetic screens are performed in this species. We discuss the first examples and prospects of approaches using sgRNAs as specific and effective mutagens. Moreover, we have reviewed methods aimed at measuring the phenotypes of single cells after their mutagenic perturbation with vectors encoding individual sgRNAs. These methods can range from different cell-based reporters to single-cell RNA sequencing and can serve as great tools for high-throughput genetic screens. PMID- 29173170 TI - First-in-human Phase 1 CRISPR Gene Editing Cancer Trials: Are We Ready? AB - A prospective first-in-human Phase 1 CRISPR gene editing trial in the United States for patients with melanoma, synovial sarcoma, and multiple myeloma offers hope that gene editing tools may usefully treat human disease. An overarching ethical challenge with first-in-human Phase 1 clinical trials, however, is knowing when it is ethically acceptable to initiate such trials on the basis of safety and efficacy data obtained from pre-clinical studies. If the pre-clinical studies that inform trial design are themselves poorly designed - as a result of which the quality of pre-clinical evidence is deficient - then the ethical requirement of scientific validity for clinical research may not be satisfied. In turn, this could mean that the Phase 1 clinical trial will be unsafe and that trial participants will be exposed to risk for no potential benefit. To assist sponsors, researchers, clinical investigators and reviewers in deciding when it is ethically acceptable to initiate first-in-human Phase 1 CRISPR gene editing clinical trials, structured processes have been developed to assess and minimize translational distance between pre-clinical and clinical research. These processes draw attention to various features of internal validity, construct validity, and external validity. As well, the credibility of supporting evidence is to be critically assessed with particular attention to optimism bias, financial conflicts of interest and publication bias. We critically examine the pre-clinical evidence used to justify the first-inhuman Phase 1 CRISPR gene editing cancer trial in the United States using these tools. We conclude that the proposed trial cannot satisfy the ethical requirement of scientific validity because the supporting pre-clinical evidence used to inform trial design is deficient.

AB - BACKGROUND: Duchenne muscular dystrophy (DMD) is an X-linked neuromuscular disease caused by the lack of dystrophin due to mutations in the DMD gene. Since dystrophin is essential in maintaining the integrity of the sarcolemmal membrane, the absence of the protein leads to muscle damage and DMD disease manifestation. Currently, there is no cure with only symptomatic management available. OBJECTIVE: The most recent advancements in DMD therapies do not provide a permanent treatment for DMD. CRISPR/Cas technology poses as an attractive platform for DMD gene therapy both dependent and independent of the specific mutation. METHOD: CRISPR/Cas technology can be utilized independent of the patient mutation by modulating disease modifiers. Regarding DMD duplication mutations, full length dystrophin can be restored using a single sgRNA approach. For DMD deletion and point mutations, the open reading frame (ORF) can be restored by removing or reframing exon(s) to produce a shorter form of dystrophin. The full-length wildtype dystrophin can also be restored using homologous recombination (HR). The CRISPR/Cas components for these strategies were delivered in vivo using the adeno-associated virus (AAV) vector. RESULTS: The upregulation of a dystrophin homologue called utrophin can compensate for the lack of dystrophin protein, and has been successfully demonstrated in patient cells. Full-length dystrophin was restored in patient cells carrying duplication mutations. The shorter form and full-length dystrophin was recovered using CRISPR strategies in vitro and in vivo. CONCLUSIONS: Restoration of the wild type and shorter form of dystrophin highlights the therapeutic potential of CRISPR technology for DMD. PMID- 29173173 TI - AR Copy Number and AR Signaling-directed Therapies in Castrationresistant Prostate Cancer. AB - BACKGROUND: Adaptive upregulation of Androgen Receptor (AR) is the most common event involved in the progression from hormone sensitive to Castration-Resistant Prostate Cancer (CRPC). AR signaling remains the main target of new AR signalling directed therapies such as abiraterone and enzalutamide in CRPC patients. OBJECTIVE: In this review, we discuss general mechanisms of resistance to AR targeted therapies, with a focus on the role of AR Copy Number (CN). We reported methods and clinical applications of AR CN evaluation in tissue and liquid biopsy, thus to have a complete information regarding its role as predictive and prognostic biomarker. CONCLUSION: Outcomes of CRPC patients are reported to be highly variable as the consequence of tumor heterogeneity. AR CN could contribute to patient selection and tumor monitoring in CRPC treated with new anti-cancer treatment as abiraterone and enzalutamide. Further studies to investigate AR CN effect to these agents and its potential combination with other prognostic or predictive clinical factors are necessary in the context of harmonized clinical trial design. PMID- 29173174 TI - Autophagy after Subarachnoid Hemorrhage: Can Cell Death be Good? AB - BACKGROUND: Autophagy is a prosurvival, reparative process that maintainsww cellular homeostasis through lysosomal degradation of selected cytoplasmic components and programmed death of old, dysfunctional, or unnecessary cytoplasmic entities. According to growing evidence, autophagy shows beneficial effects following subarachnoid hemorrhage (SAH). SAH is considered one of the most devastating forms of stroke. METHODS: In this review lies in revealing the pathophysiological pathways and the effects of autophagy. Current results from animal studies will be discussed focusing on the effects of inhibitors and inducers of autophagy. In addition, this review discusses the clinical translation of potential neuropharmacological targets that can help prevent early brain injury (EBI) following SAH by incorporating programmed cell death into clinical management. RESULTS: Published data showed that autophagy mechanisms have a prosurvival effect to reduce apoptotic cell death after SAH. However, if SAH exceeds a certain stress threshold, autophagy mechanisms lead to increased apoptotic cell death, more brain injury, and worse outcome. CONCLUSION: Future investigation on the differences and molecular switches between protective mechanisms of autophagy and excessive "self-eating" autophagy leading to cell death is needed to achieve more insight into the complex pathophysiology of brain injury after SAH. If autophagy after SAH can be controlled to lead to beneficial effects only, as the physiological self-control mechanism, this could be an important target for treatment. PMID- 29173176 TI - The SIV Envelope Glycoprotein, Viral Tropism, and Pathogenesis: Novel Insights from Nonhuman Primate Models of AIDS. AB - BACKGROUND: Cellular tropism of human immunodeficiency virus (HIV-1) is closely linked to interactions between the viral envelope glycoprotein (Env) with CD4 and chemokine receptor family members, CCR5 and CXCR4. This interaction plays a key role in determining anatomic sites that are infected in vivo and the cascade of early and late events that result in chronic immune activation, immunosuppression and ultimately, AIDS. CD4+ T cells are critical to adaptive immune responses, and their early and rapid infection in gut lamina propria and secondary lymphoid tissues in susceptible hosts likely contributes to viral persistence and progression to disease. CD4+ macrophages are also infected, although their role in HIV-1 pathogenesis is more controversial. METHODS: Pathogenic infection by simian immunodeficiency viruses (SIV) in Asian macaques as models of HIV-1 infection has enabled the impact of cellular tropism on pathogenesis to be directly probed. This review will highlight examples in which experimental interventions during SIV infection or the introduction of viral mutations have altered cellular tropism and, subsequently, pathogenesis. RESULTS: Alterations to the interaction of Env and its cellular receptors has been shown to result in changes to CD4 dependence, coreceptor specificity, and viral tropism for gut CD4+ T cells and macrophages. CONCLUSION: Collectively, these findings have yielded novel insights into the critical role of the viral Env and tropism as a driver of pathogenesis and host control and have helped to identify new areas for targeted interventions in therapy and prevention of HIV-1 infection. PMID- 29173177 TI - Integrase Strand Transfer Inhibitors and the Emergence of Immune Reconstitution Inflammatory Syndrome (IRIS). AB - BACKGROUND: Immune reconstitution inflammatory syndrome (IRIS) is a major concern when starting highly active anti-retroviral therapy (HAART) in new patients and especially late presenters. This study attempts to identify risk factors for IRIS and investigate whether certain treatment regimens increase the probability of IRIS for patients at risk. METHODS: Retrospective single-centre study of HIV patients treated with HAART. RESULTS: A total of 417 patients were included. We identified 45 cases of IRIS in 37 patients; an incidence of 13.3 cases over 1000 person-years. In univariate analysis, IRIS development was significantly associated with CDC stage, the presence of an opportunistic infection (OI) at diagnosis, CD4 cell count and viral load at diagnosis and HAART initiation and the use of integrase strand inhibitors (INSTIs). In multivariate analysis, INSTIs use (OR 2.89; 95%CI 1.26-6.64; p=0.012), CD4<=200/mm3 (OR 5.56; 95%CI 2.2-13.98; p<0.001), and the presence of an OI (OR 4.74; 95%CI 2.13-10.23; p=0.012) were independent risk factors. Among INSTI regimens, dolutegravir (OR 4.99 vs. NNRTI; 95%CI 1.11-22.55; p=0.037) and elvitegravir (OR 4.82 vs. NNRTI; 95%CI 1.43-16.19; p=0.011) seem to carry increased risk. Mortality was 18.9% (7/37) for IRIS patients compared to 9.7% (37/380) in the non-IRIS group. Mortality at any given time during follow-up was significantly higher in the IRIS group (HR 3.2; 95%CI 1.39-7.36; p=0.006). CONCLUSION: The use of INSTIs and especially DTG and EVG is associated with a higher probability for the development of IRIS in the background of late presentation and the presence of OIs. These data highlight the need for further research. PMID- 29173178 TI - Knowledge, Normative Beliefs and Attitudes Related to Recent HIV Infection among People who Inject Drugs in Athens, Greece. AB - BACKGROUND: Despite great improvements in prevention over the last years, much has to be done to reduce new human immunodeficiency virus (HIV) infections. Substantial evidence shows that the six-month period of recent HIV infection contributes disproportionately to HIV transmission. OBJECTIVE: This study aims to investigate knowledge, normative beliefs, and attitudes of people who inject drugs (PWID) regarding recent HIV infection. METHODS: People who inject drugs in Athens, Greece were recruited in the fifth round of a respondent- driven sampling program (ARISTOTLE). The participants were tested for HIV and answered a structured questionnaire, which also included items on knowledge, normative beliefs, and attitudes regarding recent infection to address needs of the social network-based Transmission Reduction Intervention Project. The multivariable analyses included logistic regression models, which produced odds ratios (OR) and 95% confidence intervals (CI). RESULTS: In total, 1,407 people (mean age: 36.3 +/ 7.9 years old; males: 81.9%) took part in the fifth round of ARISTOTLE. Of these, 61.5% knew that HIV-infected people who are not on treatment are more likely to transmit HIV during the first six months of their infection and 58.4% reported that people in their network would react positively towards a recently HIV-infected person. People who inject drugs who were knowledgeable of recent HIV infection were more likely to disagree with statements such as that one should avoid all contact with a person recently infected by HIV (adjusted OR: 1.510, 95% CI: 1.090, 2.091) or more likely to agree with statements such as that an HIV+ person is much less likely to transmit HIV when h/she is on combination antiretroviral treatment (adjusted OR: 2.083, 95% CI: 1.231, 3.523). CONCLUSION: A considerable proportion of PWID in Athens, Greece, were aware of the high HIV transmission risk of recent HIV infection, although improvement is needed for some population segments. People who inject drugs who were knowledgeable of the role of recent HIV infection were more likely to have normative beliefs and attitudes that favor behaviors that could help rather than harm or stigmatize people who have recently been infected with HIV. Interventions that are based on the role of recent HIV infection in HIV transmission could be important to HIV prevention. PMID- 29173179 TI - SIV Coreceptor Specificity in Natural and Non-Natural Host Infection: Implications for Cell Targeting and Differential Outcomes from Infection. AB - Pathogenic HIV-1 infection of humans and SIVmac infection of macaques are the result of zoonotic transfer of primate immunodeficiency viruses from their natural hosts into non-natural host species. Natural host infections do not result in pathogenesis despite high levels of virus replication, and evidence suggests that differences in anatomical location and specific subsets of CD4+ T cells infected may underlie distinct outcomes from infection. The coreceptor CCR5 has long been considered the sole pathway for SIV entry and the key determinant of CD4+ cell targeting, but it has also been known that natural hosts express exceedingly low levels of CCR5 despite maintaining high levels of virus replication. This review details emerging data indicating that in multiple natural host species, CCR5 is dispensable for SIV infection ex vivo and/or in vivo and, contrary to the established dogma, alternative coreceptors, particularly CXCR6, play a central role in infection and cell targeting. Infections of non-natural hosts, however, are characterized by CCR5-exclusive entry. These findings suggest that alternative coreceptor-mediated cell targeting in natural hosts, combined with low CCR5 expression, may direct the virus to distinct populations of cells that are dispensable for immune homeostasis, particularly extralymphoid and more differentiated CD4+ T cells. In contrast, CCR5-mediated entry in non-natural hosts results in targeting of CD4+ T cells that are located in lymphoid tissues, critical for immune homeostasis, or necessary for gut barrier integrity. Thus, fundamental differences in viral entry coreceptor use may be central determinants of infection outcome. These findings redefine the normal SIV/host relationship in natural host species, shed new light on key features linked to zoonotic immunodeficiency virus transfer, and highlight important questions regarding how and why this coreceptor bottleneck occurs and the coevolutionary equilibrium is lost following cross-species transfer that results in AIDS. PMID- 29173181 TI - Misoprostol-induced Acute Coronary Syndrome in a Premenopausal Woman: A Case Report with Literature Review. AB - BACKGROUND: Misoprostol is a synthetic analog of prostaglandin-E1 and it is the most widely used drug for the medical management of incomplete abortion. Acute Coronary Syndrome (ACS) rarely occurs in perimenopausal women, in addition, its presentation is atypical, so the disease is not always recognized. CASE REPORT: We describe a case of 39-year-old woman with no major underlying cardiovascular risk factors, who developed an episode of ACS following the administration of two doses of misoprostol. After the discontinuation of misoprostol treatment, there was a complete resolution of patient's symptoms. The case draws attention to a rare side effect of a commonly used drug and alerts the clinicians to be cautious in those patients having baseline risk factors which make the patient more susceptible to such serious adverse drug effect. PMID- 29173175 TI - Imaging the Role of Inflammation in Mood and Anxiety-related Disorders. AB - BACKGROUND: Studies investigating the impact of a variety of inflammatory stimuli on the brain and behavior have reported evidence that inflammation and release of inflammatory cytokines affect circuitry relevant to both reward and threat sensitivity to contribute to behavioral change. Of relevance to mood and anxiety related disorders, biomarkers of inflammation such as inflammatory cytokines and acute-phase proteins are reliably elevated in a significant proportion of patients with major depressive disorder (MDD), bipolar disorder, anxiety disorders and post-traumatic stress disorder (PTSD). METHODS: This review summarized clinical and translational work demonstrating the impact of peripheral inflammation on brain regions and neurotransmitter systems relevant to both reward and threat sensitivity, with a focus on neuroimaging studies involving administration of inflammatory stimuli. Recent translation of these findings to further understand the role of inflammation in mood and anxiety-related disorders is also discussed. RESULTS: Inflammation was consistently found to affect basal ganglia and cortical reward and motor circuits to drive reduced motivation and motor activity, as well as anxiety-related brain regions including amygdala, insula and anterior cingulate cortex, which may result from cytokine effects on monoamines and glutamate. Similar relationships between inflammation and altered neurocircuitry have been observed in MDD patients with increased peripheral inflammatory markers, and such work is on the horizon for anxiety disorders and PTSD. CONCLUSION: Neuroimaging effects of inflammation on reward and threat circuitry may be used as biomarkers of inflammation for future development of novel therapeutic strategies to better treat mood and anxiety-related disorders in patients with high inflammation. PMID- 29173182 TI - Lupus Nephritis: Current Treatment Paradigm and Unmet Needs. AB - BACKGROUND: Systemic Lupus Erythematosus (SLE) is an autoimmune disorder characterized by chronic inflammation, which can result in a multitude of systemic or organ-limited manifestations, including the skin, lungs, heart, and kidney. SLE nephritis is present in an average of 38% of patients at the time of diagnosis, and may occur as the initial presentation of disease with progression to End-Stage Renal Disease (ESRD) in roughly 10-20% of patients. METHODS: A review of the current literature was undertaken to investigate the evolution of treatment of SLE nephritis based on randomized trials and robust observational studies. We aimed to provide a timeline of the development of current induction and maintenance therapy, as well as the development of novel targeted therapies, all leading to current guidelines. RESULTS: Based on all available current data on standard of care therapies for SLE nephritis, there is at best a complete remission rate of 50-60%, and roughly 13-25% of patients experience periods of relapse during maintenance therapy for SLE nephritis. Therefore, the need for newer, targeted therapies has been the focus of many current, ongoing clinical trials. CONCLUSION: Standard induction and maintenance therapies at present are anti-proliferative and nonspecific, that is, interfering with the process of autoantigen presentation and activation of autoreactive leukocytes. However, newer agents with specific T-cell, B-cell, or proteasome targets are currently being investigated. PMID- 29173180 TI - The Neutralizing Antibody Response to the HIV-1 Env Protein. AB - BACKGROUND: A vaccine able to elicit broadly neutralizing antibodies capable of blocking infection by global viruses has not been achieved, and remains a key public health challenge. OBJECTIVE: During infection, a robust strain-specific neutralizing response develops in most people, but only a subset of infected people develop broadly neutralizing antibodies. Understanding how and why these broadly neutralizing antibodies develop has been a focus of the HIV-1 vaccine field for many years, and has generated extraordinary insights into the neutralizing response to HIV-1 infection. RESULTS: This review describes the features, targets and developmental pathways of early strainspecific antibodies and later broadly neutralizing antibodies, and explores the reasons such broad antibodies are not more commonly elicited during infection. CONCLUSION: The insights from these studies have been harnessed for the development of pioneering new vaccine approaches that seek to drive B cell maturation towards breadth. Overall, this review describes how findings from infected donors have impacted on active and passive immunization approaches that seek to prevent HIV-1 infection. PMID- 29173183 TI - A comparison of fucoidan conjugated to paclitaxel and curcumin for the dual delivery of cancer therapeutic agents. AB - The aim of this study was to develop and compare polymeric micelles of fucoidan, a sulfated polysaccharide, and hydrophobic drugs such as paclitaxel and curcumin. Paclitaxel and curcumin are both known for their medicinal properties, including anticancer efficacy. However, their very low water solubility, absorption and rapid metabolism leads to reduced bioavailability. To redress these problems and enhance anti-cancer therapeutics using fucoidan, polymeric micelles were synthesized from conjugates of fucoidan and hydrophobic drugs. The chemical conjugation of fucoidan and hydrophobic drugs has been achieved by utilizing reactive functional groups on the molecules, such as carboxylic groups and hydroxyl groups. The micelles revealed a homogeneous spherical morphology, size, negative surface charge. Fourier transform infrared spectroscopy was used to investigate the physicochemical properties of the polymeric micelles, which form a self-assembled polymeric micelle in aqueous medium. The results of the in vitro release of curcumin and fucoidan showed that their release rates were higher at a pH of 4.5 than at a pH of 7.4. In contrast, the paclitaxel conjugate had a similar release profile at pH of 4.5 and pH of 7.4. In the present work, we also found an effective drug delivery system that had the ability to release two types of anticancer drugs, fucoidan and hydrophobic drugs, in the tumour environment. PMID- 29173184 TI - Natural Compounds in the Chemoprevention of Malignant Melanoma. AB - Malignant melanoma is a very aggressive form of skin cancer, with increasing rates every year, with an etiology that derives from the transformation and uncontrolled growth of melanocytes. There are several treatment options which can be used as unique treatment or combined, depending upon the stage of melanoma including surgical excision, chemotherapy, immunotherapy, targeted therapy. Plant Kingdom displays an unequalled potential for the synthesis of highly diversified chemical structures. Although natural compounds are synthesized in order to help the plant to interact with the environment, a large number of phytochemicals act as drugs within the human or animal body by activating various biochemical pathways. The study aims to review another approach in the management of this highly aggressive form of skin cancer, namely the effect of natural compounds in the chemoprevention of malignant melanoma. PMID- 29173185 TI - A Review on Melatonin's Effects in Cancer: Potential Mechanisms AB - This systematic review aims to elucidate the role of melatonin (N-acetyl-5-metoxy tryptamine) (MLT) in the prevention and treatment of cancer. MLT is a pineal gland secretory product, an evolutionarily highly conserved molecule; it is also an antioxidant and an impressive protector of mitochondrial bioenergetic activity. MLT is characterized by an ample range of activities, modulating the physiology and molecular biology of the cell. Its physiological functions relate principally to the interaction of G protein-coupled MT1 and MT2 trans-membrane receptors (GPCRs), a family of guanidine triphosphate binding proteins. MLT has been demonstrated to suppress the growth of various tumours both, in vivo and in vitro. In this review, we analyze in depth, the antioxidant activity of melatonin, aiming to illustrate the cancer treatment potential of the molecule, by limiting or reversing the changes occurring during cancer development and growth. PMID- 29173186 TI - Comparison of Physicochemical Properties of Generic Doxorubicin HCl Liposome Injection with the Reference Listed Drug. AB - BACKGROUND: Liposomal doxorubicin is widely used for treating ovarian cancer and Kaposi's sarcoma. Encapsulation of doxorubicin in highly complex polyethylene glycol-coated (stealth) liposomes prolongs residence time and avoids the systemic toxicity associated with administration of the free drug. Small variations in physicochemical properties introduced during manufacture of liposomes can influence the payload of encapsulated drug, stability of liposomes under physiological conditions, and release of drug at the target tissue. Accordingly, the US Food and Drug Administration and the European Medicines Agency have issued guidance for manufacturers of generic liposomal doxorubicin that is designed to ensure that more than 30 physicochemical parameters that influence its safety and efficacy should be similar in the generic and reference listed drugs. OBJECTIVE: This study aims to describe the physicochemical characterization procedures used to ensure consistency between batches of generic liposomal doxorubicin and with the reference listed drug. METHODS: A range of spectroscopic, chromatographic, and other physicochemical tests was used to compare relative concentrations of liposome components, liposome morphology, ratios of free/entrapped doxorubicin, stability, and in vitro doxorubicin release rates in physiologically and clinically relevant media. RESULTS: The tests established that generic and reference liposomes contained similar concentrations of drug, lipids, and excipients and that their physical forms were also similar. CONCLUSION: The results of the tests demonstrate the physicochemical equivalence of generic liposomal doxorubicin hydrochloride and the reference listed drug, Doxil(r)/Caelyx(r). Biochemical and clinical equivalence must also be demonstrated to fully meet regulatory requirements for generic liposomal medicines, and these are the subjects of separate studies. PMID- 29173187 TI - Trichinella spiralis and tumors: cause, coincidence or treatment? AB - Conventional therapeutic strategies for tumors have had limited success, and innovative and more effective approaches to treatment are urgently required. The ancient idea that various biological, bacterial, yeast, viral, and parasitic agents can be used as cancer therapeutics has gradually attracted considerable interest. Certain parasites have been widely discussed in association with human and animal tumors. Many researches have provided proofs that Trichinella spiralis (T. spiralis) possesses antitumor activities. The antitumor effect of T. spiralis was first described in the 1970s. However, its research has been inconsistent, and little progress has been made in this field. Therefore, the mechanisms underlying these inhibitory effects are still unclear, and convincing evidence of the links between T. spiralis and the prevention or treatment of tumors from clinical trials is absent. Meanwhile, some other researches also suggested that T. spiralis may cause or contribute to coinfection with a tumors. In this review, evidence for T. spiralis to act as a pro- or antitumorigenic agent is summarized and discussed, in hope of contributing to a better understanding of the relations between T. spiralis and tumors. PMID- 29173188 TI - Innate Immune Surveillance in the Central Nervous System Following Legionella pneumophila Infection. AB - BACKGROUND & OBJECTIVE: The innate immune response is a common occurrence in many neuroinflammatory diseases. Central Nervous System (CNS) resident immune cells are able to detect and react to infections and sterile trauma. Peripheral immune cell migration into CNS is regulated by the blood-brain barrier, although peripheral immune cells can invade CNS through meninges, choroid plexus, perivascular spaces, and cerebrospinal fluid. Consequently, in the brain, immune reactions can be mediated by both resident and peripheral immune cells. Both in the periphery and within the CNS, innate immune response is regulated by a wide array of pattern recognition receptors, including Tolllike, scavenger, Retinoic Acid-inducible Gene-1 like, and nucleotide-binding oligomerization domainslike responsible for inflammasome formation. Inflammasome pathway activation induces pyroptosis, a highly inflammatory cell death pattern that occurs to remove intracellular pathogens. Legionella pneumophila is an intracellular microorganism responsible for Legionnaires' disease, a lung infection always associated to neurological dysfunctions. Recent studies have been shown that Toll-like receptors, nucleotide-binding oligomerization domains-like receptors, and RIG-1 like, are activated by L. pneumophila. This flagellated bacterium is able to replicate in phagocytic cells, including macrophages and microglia, responding by activating inflammasome pathways that may be the cause of CNS dysfunction detected in several infected patients. CONCLUSION: The aim of this review is to bring together the latest findings concerning L. pneumophila infection and innate immune host cell responses. A deeper knowledge of these processes could allow the use of immunomodulatory compounds able to counteract CNS involvement following L. pneumophila infection. PMID- 29173189 TI - Quality of Life in Individuals Affected by Arnold Chiari Malformation: Comparison and Validation of a Measurement Instrument. AB - BACKGROUND: Introduction. Arnold Chiari Malformation (ACM) type I is a pathology whose symptomatology has repercussions for the quality of life of those affected by it. Quality-of-life measurement instruments can allow the severity of the impact of Chiari type I malformation on patients' lives to be monitored. The Chiari Symptom Profile (CSP) is a valid and reliable instrument designed for this purpose. The aim of the study was to adapt the CSP to Spanish and to explore the reliability and validity of this construct in the context of Spanish-speaking patients with ACM. METHODS: The English CSP instrument has a good internal validity and consistency. We used a standardized procedure for the linguistic validation of the translated scale. For the psychometric validation, we recruited 215 individuals with ACM and calculated the Cronbach's alpha for the sample. The construct was validated by analyzing the age, sex, and presence of syringomyelia, as well as by correlating the results with the sickness impact profile 30 (SIP 30) questionnaire, which can also evaluate quality of life in this type of patient. RESULTS: The Spanish version of the CSP has good internal consistency and validity (Cronbach's alpha of 0.90); age, sex, and the presence of syringomyelia does not significantly affect the quality of life of patients with ACM. There was a direct and significant correlation between the Spanish CSP and the validated SIP-30 questionnaire results (p < 0.05). Further analysis showed a positive correlation for the physical and psychological scopes of the CSP and SIP 30 questionnaires, but not for their functional and social scopes. CONCLUSION: This version of the CSP is a valid and reliable instrument for measuring quality of life in patients with ACM in the Spanish context. PMID- 29173190 TI - Migraine in Systemic Autoimmune Diseases. AB - BACKGROUND AND OBJECTIVE: Migraine and systemic autoimmune diseases are 2-3-fold more common in women and various studies have reported an association between the two pathologies. METHODS: This review takes into account epidemiological studies involving migraine and systemic lupus erythematosus, antiphospholipid syndrome, Sjogren's syndrome, and other diffuse connective tissue diseases. This scientific literature analysis consists of the main articles found in Medline with a search up to April 2017. RESULTS: Many epidemiological studies were carried out on patients suffering from systemic lupus erythematosus. Results showed that headache and migraine are more prevalent in systemic lupus erythematosus patients compared to controls, especially migraine with aura. Patients with Lupus and migraine show a higher lupus activity and association with Raynaud and/or antiphospholipids in these populations are contradictory. There are not enough data to establish an association between antiphospholipid syndrome and migraine. However, data are more consistent between antiphospholipid carrier condition and migraine. Systemic sclerosis is a rare disease, for this reason the amount of available data on this disorder are scanty. However, some studies reported an association between headache, migraine and systemic sclerosis, especially where gliotic brain lesions and Raynaud are coexisting. Finally, large propensity cohort population based studies suggested that systemic autoimmune diseases are more frequent in patients suffering from migraine. CONCLUSION: An attempt at explaining the possible link between these disorders and migraine is discussed at the end of the review. Several autoimmune alterations are shared by most autoimmune diseases and headache types. Endothelial dysfunction is the only alteration that is common among all these disorders. PMID- 29173191 TI - Relevant Patented Biotechnological Applications of Ecotin : An Update. AB - BACKGROUND: Ecotins are serine protease inhibitors which are generally found in the periplasmic compartment. These inhibitors act on a wide range of serine proteases with different efficiencies. Actually, only few Ecotins were studied, and the main characterized proteins derived from Escherichia coli. Functional studies of this latter protein allowed the development of numerous patents related to Ecotin relevant biotechnological applications. OBJECTIVE: This review aims to give an update on the relevant Ecotins already described and to provide a concise overview concerning the relevant patented applications of these serine protease inhibitors. METHOD: In this review, we focus on the analysis of Ecotin diversity and their distribution using Pfam protein data base. Moreover, we report a detailed overview regarding the biotechnological applications of the Ecotins based on all patents associated to Ecotins and their biotechnological applications searched in European Patent Office (Espacenet), United States Patent and National Patent Collections (WIPO) patents databases. RESULTS: On the basis of this analysis we demonstrate that Ecotins are mostly present in bacteria. Study of Ecotin sequences and their biochemical properties reveals that they are a small serine protease inhibitor group. The high stability and specificity of Ecotins promote their biotechnological uses in several fields. The original structure organization of Ecotin-protease complexes and their flexibility leads to several patented applications. CONCLUSION: This review showed that Ecotins have many attractive biotechnological applications. Potential of Ecotins needs to be more investigated seeing the limited available data related to this protein family. Thus, further functional analyses will promote the use of Ecotins. PMID- 29173192 TI - The Ecstacy of Gold: Patent Expirations for Trastuzumab, Bevacizumab, Rituximab, and Cetuximab. AB - OBJECTIVE: Fully humanized monoclonal antibodies have revolutionized the treatment of many solid tumors, including ovarian, lung, colorectal, and breast cancer. Among the most widely used monoclonal antibodies in clinical oncology are cetuximab, trastuzumab, rituximab, and bevacizumab. METHODS: This is a review article focusing on the drug patents for cetuximab, trastuzumab, rituximab, and bevacizumab. RESULTS: These four monoclonal antibodies are used in both first and second line treatment regimens for multiple common malignancies. With recent patent expirations, pharmaceutical companies involved in biosimilar manufacture are looking to establish ownership over these financial monopolies. CONCLUSION: This article will review these four notable monoclonal antibodies, their role in clinical oncology, and the drug patents that are nearing expiration. There are currently only two biosimilars approved in the United States: the trastuzumab biosimilar trastuzumab-dkst (Ogivri) and the bevacizumab biosimilar bevacizumab awwb (Mvasi). In Europe, SB3, a trastuzumab biosimilar, is approved for use as well as two rituzimab biosimilars, truxima and rixathon. PMID- 29173194 TI - Sex similarities and differences in risk factors for recurrence of major depression. AB - BACKGROUND: Major depression (MD) occurs about twice as often in women as in men, but it is unclear whether sex differences subsist after disease onset. This study aims to elucidate potential sex differences in rates and risk factors for MD recurrence, in order to improve prediction of course of illness and understanding of its underlying mechanisms. METHODS: We used prospective data from a general population sample (n = 653) that experienced a recent episode of MD. A diverse set of potential risk factors for recurrence of MD was analyzed using Cox models subject to elastic net regularization for males and females separately. Accuracy of the prediction models was tested in same-sex and opposite-sex test data. Additionally, interactions between sex and each of the risk factors were investigated to identify potential sex differences. RESULTS: Recurrence rates and the impact of most risk factors were similar for men and women. For both sexes, prediction models were highly multifactorial including risk factors such as comorbid anxiety, early traumas, and family history. Some subtle sex differences were detected: for men, prediction models included more risk factors concerning characteristics of the depressive episode and family history of MD and generalized anxiety, whereas for women, models included more risk factors concerning early and recent adverse life events and socioeconomic problems. CONCLUSIONS: No prominent sex differences in risk factors for recurrence of MD were found, potentially indicating similar disease maintaining mechanisms for both sexes. Course of MD is a multifactorial phenomenon for both males and females. PMID- 29173193 TI - Polygenic prediction of the phenome, across ancestry, in emerging adulthood. AB - BACKGROUND: Identifying genetic relationships between complex traits in emerging adulthood can provide useful etiological insights into risk for psychopathology. College-age individuals are under-represented in genomic analyses thus far, and the majority of work has focused on the clinical disorder or cognitive abilities rather than normal-range behavioral outcomes. METHODS: This study examined a sample of emerging adults 18-22 years of age (N = 5947) to construct an atlas of polygenic risk for 33 traits predicting relevant phenotypic outcomes. Twenty eight hypotheses were tested based on the previous literature on samples of European ancestry, and the availability of rich assessment data allowed for polygenic predictions across 55 psychological and medical phenotypes. RESULTS: Polygenic risk for schizophrenia (SZ) in emerging adults predicted anxiety, depression, nicotine use, trauma, and family history of psychological disorders. Polygenic risk for neuroticism predicted anxiety, depression, phobia, panic, neuroticism, and was correlated with polygenic risk for cardiovascular disease. CONCLUSIONS: These results demonstrate the extensive impact of genetic risk for SZ, neuroticism, and major depression on a range of health outcomes in early adulthood. Minimal cross-ancestry replication of these phenomic patterns of polygenic influence underscores the need for more genome-wide association studies of non-European populations. PMID- 29173195 TI - Primary versus secondary tracheoesophageal puncture: systematic review and meta analysis. AB - BACKGROUND: Tracheoesophageal puncture represents the 'gold standard' for voice restoration following laryngectomy. Tracheoesophageal puncture can be undertaken primarily during laryngectomy or in a separate secondary procedure. There is no current consensus on which approach is superior. The current evidence comparing primary and secondary tracheoesophageal puncture was assessed. METHODS: A systematic review and meta-analysis of articles comparing outcomes for primary and secondary tracheoesophageal puncture after laryngectomy were conducted. Outcome measures were: voice success, overall complication rate and pharyngocutaneous fistula rate. RESULTS: Eleven case series met the inclusion criteria, two prospective and nine retrospective. Meta-analysis did not demonstrate statistically significant differences in overall complication rate or voice outcomes, though it suggested a significantly increased risk of pharyngocutaneous fistula in primary compared to secondary tracheoesophageal puncture. CONCLUSION: Primary tracheoesophageal puncture is a safe and efficient approach for voice rehabilitation. However, secondary tracheoesophageal puncture should be preferred where there is a higher risk of pharyngocutaneous fistula. PMID- 29173196 TI - Person-fit feedback on inconsistent symptom reports in clinical depression care. AB - BACKGROUND: Depressive patients can present with complex and different symptom patterns in clinical care. Of these, some may report patterns that are inconsistent with typical patterns of depressive symptoms. This study aimed to evaluate the validity of person-fit statistics to identify inconsistent symptom reports and to assess the clinical usefulness of providing clinicians with person fit score feedback during depression assessment. METHODS: Inconsistent symptom reports on the Inventory of Depressive Symptomatology Self-Report (IDS-SR) were investigated quantitatively with person-fit statistics for both intake and follow up measurements in the Groningen University Center of Psychiatry (n = 2036). Subsequently, to investigate the causes and clinical usefulness of on-the-fly person-fit alerts, qualitative follow-up assessments were conducted with three psychiatrists about 20 of their patients that were randomly selected. RESULTS: Inconsistent symptom reports at intake (12.3%) were predominantly characterized by reporting of severe symptoms (e.g. psychomotor slowing) without mild symptoms (e.g. irritability). Person-fit scores at intake and follow-up were positively correlated (r = 0.45). Qualitative interviews with psychiatrists resulted in an explanation for the inconsistent response behavior (e.g. complex comorbidity, somatic complaints, and neurological abnormalities) for 19 of 20 patients. Psychiatrists indicated that if provided directly after the assessment, a person fit alert would have led to new insights in 60%, and be reason for discussion with the patient in 75% of the cases. CONCLUSIONS: Providing clinicians with automated feedback when inconsistent symptom reports occur is informative and can be used to support clinical decision-making. PMID- 29173197 TI - Prevalence of breast-feeding and exclusive breast-feeding at 48 h after birth and up to the sixth month in Cyprus: the BrEaST start in life project. AB - OBJECTIVE: To assess the prevalence and sociodemographic determinants of breast feeding (BF) and exclusive breast-feeding (EBF) in Cyprus up to the sixth month. DESIGN: Cross-sectional and longitudinal descriptive study. BF and EBF were estimated based on mothers' self-reported BF status in line with Step 7 of the WHO/UNICEF Baby-Friendly Hospital Initiative questionnaire and based on 24 h recall. SETTING: Maternity wards in all public hospitals and twenty-nine (of thirty-five) private maternity clinics nationwide. SUBJECTS: Consecutive sample of 586 mothers recruited within 48 h from birth, followed up by telephone interview at the first, fourth and sixth month. RESULTS: Although 84.3 % of mothers initiated BF before discharge, prevalence of BF at the sixth month was 32.4 %, with the highest reduction observed between the first and fourth months. Prevalence of EBF at 48 h was 18.8 % and fell gradually to 5.0 % at the sixth month. Mothers with higher educational attainment or higher family income were more likely to breast-feed until the sixth month. In terms of EBF, an association was observed only with education, which persisted until the sixth month. Other than social gradient, mode of delivery was the strongest determinant of BF initiation, exclusivity and continuation. Mothers who gave birth vaginally were three to four times more likely to initiate BF (OR=3.1; 95 % CI 1.7, 5.4) and EBF (OR=4.3; 95 % CI 2.7, 6.8). CONCLUSIONS: The low prevalence of BF and EBF in Cyprus, together with the fact that caesarean section rates are currently among the highest in Europe, suggest the need for further research to understand this multidimensional phenomenon and for interdisciplinary policy action to protect, promote and support BF. PMID- 29173198 TI - Maternal dietary supplementation with ferrous N-carbamylglycinate chelate affects sow reproductive performance and iron status of neonatal piglets. AB - Iron-deficiency anemia is a public health concern that frequently occurs in pregnant mammals and neonatal offspring. Ferrous N-carbamylglycinate chelate (Fe CGly) is a newly designed iron fortifier with proven effects in iron-deficient rats and weanling piglets. However, the effects of this new compound on pregnant mammals are unknown. Therefore, this experiment was conducted to evaluate the effects of Fe-CGly on sow reproductive performance and iron status of both sows and neonatal piglets. A total of 40 large-white sows after second parity were randomly assigned to two groups (n=20). They were receiving a diet including 80 mg Fe/kg as FeSO4 or Fe-CGly, respectively, from day 85 of gestation to parturition. The serum (day 110 of pregnancy) and placentas of sows were sampled. Litter size, mean weight of live born piglets, birth (live) litter weight, number of live born piglets, and the number of still-born piglets, mummies, and weak born piglets were recorded. Once delivered, eight litters were randomly selected from the 20 litters per treatment, and one new-born male piglet (1.503+/-0.142 kg) from each selected litter was slaughtered within 3 h after birth from the selected litters, without colostrum ingestion. The serum, longissimus muscle, liver and kidneys of the piglets were collected. The iron status of the serum samples and the messenger RNA level of iron-related genes in the placenta, liver and kidney were analyzed. The results showed that litter weight of live born piglets was higher (P=0.030) in the Fe-CGly group (19.86 kg) than in the FeSO4 group (17.34 kg). Fe-CGly significantly increased placental iron concentration (P<0.05) of sows. It also significantly increased iron saturation and reduced the total iron-binding capacity of piglets (P<0.05) at birth. However, the results revealed that supplementation of Fe-CGly in sows reduced liver and kidney iron concentration of neonatal piglets (P<0.05), indicating decreased iron storage. In addition, the concentration of iron in the colostrum was not significantly changed. Therefore, the present results suggested that replacement of maternal FeSO4 supplement with Fe-CGly in the late-gestating period for sows could improve litter birth weight, probably via enhanced iron transportation in the placenta. PMID- 29173199 TI - Effects of prenatal n-3 fatty acid supplementation on offspring resolvins at birth and 12 years of age: a double-blind, randomised controlled clinical trial. AB - Resolution of inflammation is an active process involving specialised pro resolving mediators (SPM) generated from the n-3 fatty acids EPA and DHA. n-3 Fatty acid supplementation during pregnancy may provide an intervention strategy to modify these novel SPM. This study aimed to assess the effect of n-3 fatty acid supplementation in pregnancy on offspring SPM at birth and 12 years of age (12 years). In all, ninety-eight atopic pregnant women were randomised to 3.7 g daily n-3 fatty acids or a control (olive oil), from 20 weeks gestation until delivery. Blood was collected from the offspring at birth and at 12 years. Plasma SPM consisting of 18-hydroxyeicosapentaenoic acid (18-HEPE), E-series resolvins, 17-hydroxydocosahexaenoic acid (17-HDHA), D-series resolvins, 14 hydroxydocosahexaenoic acid (14-HDHA), 10 S,17S-dihydroxydocosahexaenoic acid, maresins and protectin 1, were measured by liquid chromatography-tandem MS. We identified the resolvins RvE1, RvE2, RvE3, RvD1, 17R-RvD1 and RvD2 for the first time in human cord blood. n-3 Fatty acids increased cord blood 18-HEPE (P<0.001) derived from EPA relative to the control group. DHA-derived 17-HDHA at birth was significantly increased in the n-3 fatty acid group relative to the controls (P=0.001), but other SPM were not different between the groups. n-3 Fatty acid supplementation during pregnancy was associated with an increase in SPM precursors in the offspring at birth but the effects were not sustained at 12 years. The presence of these SPM, particularly at birth, may have functions relevant in the newborn that remain to be established, which may be useful for future investigations. PMID- 29173200 TI - New microsatellites revealed strong gene flow among populations of a new outbreak pest, Athetis lepigone (Moschler). AB - Athetis lepigone (Moschler) (Lepidoptera: Noctuidae) is a new outbreak pest in China. Consequently, it is unclear whether the emergence and spread of the outbreak of this pest are triggered by rapid in situ population size increases in each outbreak area, or by immigrants from a potential source area in China. In order to explore the outbreak process of this pest through a population genetics approach, we developed ten novel polymorphic expressed sequence tags (EST) derived microsatellites. These new microsatellites had moderately high levels of polymorphism in the tested population. The number of alleles per locus ranged from 3 to 19, with an average of 8.6, and the expected heterozygosity ranged from 0.269 to 0.783. A preliminary population genetic analysis using these new microsatellites revealed a lack of population genetic structure in natural populations of A. lepigone. The estimates of recent migration rate revealed strong gene flow among populations. In conclusion, our study developed the first set of EST-microsatellite markers and shed a new light on the population genetic structure of this pest in China. PMID- 29173201 TI - Duration of untreated psychosis and neurocognitive functioning in first-episode psychosis: a systematic review and meta-analysis. AB - BACKGROUND: Previous reviews suggest there is minimal evidence for an association between duration of untreated psychosis (DUP) and neurocognition. This is based on tallied findings of studies with small samples and neurocognition viewed as a single construct. We aimed to conduct a systematic review and meta-analysis examining the association between DUP and individual neurocognitive domains and tests in first-episode psychosis (FEP). METHOD: MOOSE and PRISMA guidelines were followed. Forty-three studies involving 4647 FEP patients were included. For studies providing correlations between DUP and neurocognition, 12 separate meta analyses were performed based on neurocognitive domains/indices. The influence of demographic/clinical variables was tested using weighted linear meta-regression analyses. RESULTS: The relationship between DUP and most neurocognitive domains/indices was not significant. Longer DUP was associated with a larger cognitive deterioration index, i.e. current minus premorbid intellectual functioning (N = 4; mean ES -0.213, 95% confidence interval (CI) (-0.344 to 0.074), p = 0.003). Findings were homogeneous, with no evidence of publication bias or significant influence from moderators. For studies providing mean and standard deviations for neurocognitive measures and DUP, 20 meta-regressions were performed on individual neurocognitive tests. One significant finding emerged showing that longer DUP was associated with fewer Wisconsin Card Sorting Test perseverative errors (mean ES -0.031, 95% CI (-0.048 to -0.013), p < 0.001). Exploratory meta-regressions in studies with mean DUP <360 days showed longer DUP was significantly associated with poorer performance on Trail Making Test A and B and higher Full-Scale IQ. CONCLUSION: There may not be a generalised association between DUP and neurocognition, however, specific cognitive functions may be associated with longer DUP or delayed help-seeking. PMID- 29173202 TI - Necrotising otitis externa in the immunocompetent patient: case series. AB - BACKGROUND: Necrotising otitis externa can be a devastating form of otitis externa. It typically tends to affect patients who are immunocompromised or diabetic. To date, there is very little in the literature about necrotising otitis externa in the immunocompetent patient population. CASE REPORTS: The present paper discusses both the clinical and radiological findings in three cases of necrotising otitis externa in an immunocompetent patient cohort. The common factor among all three patients was their advanced age. CONCLUSION: Diagnosing necrotising otitis externa can be challenging because of the potentially non-specific symptoms and the absence of early radiological signs, particularly if patients are neither immunocompromised nor diabetic. Elderly patients should be considered in the same light as immunocompromised and diabetic patients in the context of necrotising otitis externa. PMID- 29173204 TI - Limitations of the Echinococcus granulosus genome sequence assemblies for analysis of the gene family encoding the EG95 vaccine antigen. AB - Echinococcus granulosus is an important zoonotic parasite that is distributed worldwide. The EG95 vaccine was developed to assist with control of E. granulosus transmission through the parasite's livestock intermediate hosts. The vaccine is based on a recombinant antigen encoded by a gene which is a member of a multi gene family. With the recent availability of two E. granulosus draft genomes, we sought to map the eg95 gene family to the genomes. We were unable to map unequivocally any of the eg95 gene family members which had previously been characterized by cloning and sequencing both strands of genomic DNA fragments. Our inability to map EG95-related genes to the genomes has revealed limitations in the assembled sequence data when utilized for gene family analyses. This study contrasts with the expectations expressed in often high-profile publications describing draft genomes of parasitic organisms, highlighting deficiencies in currently available genomic resources for E. granulosus and provides a cautionary note for research which seeks to utilize these genome datasets. PMID- 29173203 TI - 25(OH)D3-enriched or fortified foods are more efficient at tackling inadequate vitamin D status than vitamin D3. AB - The ability to synthesise sufficient vitamin D through sunlight in human subjects can be limited. Thus, diet has become an important contributor to vitamin D intake and status; however, there are only a few foods (e.g. egg yolk, oily fish) naturally rich in vitamin D. Therefore, vitamin D-enriched foods via supplementing the animals' diet with vitamin D or vitamin D fortification of foods have been proposed as strategies to increase vitamin D intake. Evidence that cholecalciferol (vitamin D3) and calcifediol (25(OH)D3) content of eggs, fish and milk increased in response to vitamin D3 supplementation of hens, fish or cows' diets was identified when vitamin D-enrichment studies were reviewed. However, evidence from supplementation studies with hens showed only dietary 25(OH)D3, not vitamin D3 supplementation, resulted in a pronounced increase of 25(OH)D3 in the eggs. Furthermore, evidence from randomised controlled trials indicated that a 25(OH)D3 oral supplement could be absorbed faster and more efficiently raise serum 25(OH)D concentration compared with vitamin D3 supplementation. Moreover, evidence showed the relative effectiveness of increasing vitamin D status using 25(OH)D3 varied between 3.13 and 7.14 times that of vitamin D3, probably due to the different characteristics of the investigated subjects or study design. Therefore, vitamin D-enrichment or fortified foods using 25(OH)D3 would appear to have advantages over vitamin D3. Further well-controlled studies are needed to assess the effects of 25(OH)D3 enriched or fortified foods in the general population and clinical patients. PMID- 29173205 TI - Effect of maternal dyslipidaemia on the cardiorespiratory physiology and biochemical parameters in male rat offspring. AB - The present study evaluated the effects of maternal dyslipidaemia on blood pressure (BP), cardiorespiratory physiology and biochemical parameters in male offspring. Wistar rat dams were fed either a control (CTL) or a dyslipidaemic (DLP) diet during pregnancy and lactation. After weaning, both CTL and DLP offspring received standard diet. On the 30th and 90th day of life, blood samples were collected for metabolic analyses. Direct measurements of BP, respiratory frequency (RF), tidal volume (VT) and ventilation (VE) under baseline condition, as well as during hypercapnia (7 % CO2) and hypoxia (KCN, 0.04 %), were recorded from awake 90-d-old male offspring. DLP dams exhibited raised serum levels of total cholesterol (TC) (4.0-fold), TAG (2.0-fold), VLDL+LDL (7.7-fold) and reduced HDL-cholesterol (2.4-fold), insulin resistance and hepatic steatosis at the end of lactation. At 30 d of age, the DLP offspring showed an increase in the serum levels of TC (P<0.05) and VLDL+LDL (P<0.05) in comparison with CTL offspring. At 90 d of age, DLP offspring exhibited higher mean arterial pressure (MAP, approximately 34 %). In the spectral analysis, the DLP group showed augmented low-frequency (LF) power and LF:high-frequency (HF) ratio when compared with CTL offspring. In addition, the DLP animals showed a larger delta variation in arterial pressure after administration of the ganglionic blocker (P=0.0003). We also found that cardiorespiratory response to hypercapnia and hypoxia was augmented in DLP offspring. In conclusion, the present data show that maternal dyslipidaemia alters cardiorespiratory physiology and may be a predisposing factor for hypertension at adulthood. PMID- 29173206 TI - Duration of untreated prodromal symptoms in a Chinese sample at a high risk for psychosis: demographic, clinical, and outcome. AB - BACKGROUND: The duration of untreated psychosis (DUP) has been widely studied. However, for individuals with attenuated psychosis syndrome (APS), it is unclear whether the duration of untreated prodromal symptoms (DUPrS) also has a negative effect on the progression of psychosis. Our aim was to identify demographic and clinical factors contributing to the DUPrS in a large sample of individuals with APS, and to evaluate the association between DUPrS and the conversion to psychosis. METHOD: A sample of 391 individuals with APS, who were identified through a structured interview for prodromal syndromes, were included in this study, of whom a total of 334 patients had completed at least a 1-year clinical follow-up. A total of 57 individuals had converted to psychosis. RESULTS: The average DUPrS was 4.8 months for the whole sample. Individuals with a longer DUPrS were likely to be men, non-local residents, with abnormal thought symptoms, a higher severity level of negative symptoms, the lower severity level of general symptoms, and lower level of general function before the onset of attenuated positive symptoms. A DUPrS of less than 2 months, or more than 6 months, lowered the risk for conversion to psychosis. CONCLUSIONS: Our data suggested that the association between the DUPrS and outcome in individuals with APS were likely to be different, which is either long or short DUPrS was not related to future psychosis onset. Individuals with APS were more likely to have a group of features associated with a longer DUPrS. PMID- 29173207 TI - Impact of an intervention programme on knowledge, attitudes and practices of population regarding severe fever with thrombocytopenia syndrome in endemic areas of Lu'an, China. AB - Knowledge, attitudes and practices (KAP) of the population regarding severe fever with thrombocytopenia syndrome (SFTS) in endemic areas of Lu'an in China were assessed before and after an intervention programme. The pre-intervention phase was conducted using a sample of 425 participants from the 12 selected villages with the highest rates of endemic SFTS infection. A predesigned interview questionnaire was used to assess KAP. Subsequently, an intervention programme was designed and applied in the selected villages. KAP was re-assessed for each population in the selected villages using the same interview questionnaire. Following 2 months of the programme, 339 participants had completed the re assessed survey. The impact of the intervention programme was evaluated using suitable statistical methods. A significant increase in the KAP and total KAP scores was noted following the intervention programme, whereas the proportion of correct knowledge, the positive attitudes and the effective practices toward SFTS of respondents increased significantly. The intervention programme was effective in improving KAP level of SFTS in populations that were resident in endemic areas. PMID- 29173208 TI - Dietary supplementation with cysteine prevents adverse metabolic outcomes of repeated cures with paracetamol in old rats. AB - Cysteine (Cys), a conditionally indispensable amino acid, is required for the detoxification of paracetamol (acetaminophen, N-acetyl-para-aminophenol, 4 hydroxy-acetanilide, APAP), a drug of widespread use in older persons. We recently reported that repeated APAP cures could worsen sarcopenia in old rats, likely to be due to the impairment of Cys/GSH homoeostasis. The aim of the study was to evaluate whether a dietary Cys supplementation during APAP cures could improve Cys/GSH homoeostasis and thus preserve skeletal muscle. Male 21.5-month old Wistar rats received three 2-week-long cures of APAP (1 % of diet) alone or with extra Cys (0.5 % of diet), intercalated with washout periods of 2 weeks (APAP and APAP-Cys groups, respectively). They were compared with untreated control rats (CT group). CT and APAP-Cys groups were pair-fed to the APAP group. Dietary Cys supplementation was efficient to prevent increase in liver mass (P<0.0001), decrease in liver GSH (P<0.0001), increase in blood GSH concentration (P<0.0001), and to some extent, decrease in plasma free Cys concentration (P<0.05), all induced by repeated APAP cures. The addition of Cys to APAP cures decreased plasma alanine transaminase (P<0.05), the fractional synthesis rate of liver proteins (P<0.01), and increased masses of extensor digitorum longus (P<0.01), and soleus (P<0.05), compared with the APAP group. Cys supplementation prevented alteration in Cys/GSH homoeostasis and increased some muscle masses in old rats under repeated cures with a non-toxic dose of APAP. PMID- 29173209 TI - Time-series responses of swine plasma metabolites to ingestion of diets containing myo-inositol or phytase. AB - The effect of the ingestion of diets containing either myo-inositol or exogenous phytase on plasma metabolites was examined using 29 kg barrows. The diets were: control (maize, soya, rapeseed, rice bran), control plus 2 g/kg myo-inositol, control plus 1000 phytase units (FYT)/kg or 3000 FYT/kg exogenous phytase. Pigs were housed in a PigTurn device and blood was collected, from jugular catheters, via an automated system at -30, (30 min before feeding), 0, 15, 30, 45, 60, 90, 120, 150, 180, 240, 300 and 360 min post-feeding. The addition of 2 g/kg myo inositol to the basal diet resulted in an increase in plasma myo-inositol concentration that was evident 45-60 min after diet introduction and persisted to 360 min post-feeding. Similarly, supplementation of the basal diet with either 1000 or 3000 FYT/kg exogenous phytase resulted in an increase in plasma myo inositol concentration that was still rising 360 min post-feeding. Plasma P concentration was increased over time by the addition of 1000 and 3000 FYT/kg phytase, but not by the addition of myo-inositol. Other plasma metabolites examined were not affected by dietary treatment. It can be concluded that oral delivery of myo-inositol results in rapid increase in plasma myo-inositol concentrations that peak approximately 45-60 min after feeding. Use of supplemental phytase achieves similar increases in myo-inositol concentration in plasma but the appearance is more gradual. Furthermore, supplementation of pig diets with exogenous phytase results in rapid appearance of P in plasma that may be sustained over time relative to diets with no added phytase. PMID- 29173211 TI - Associations between Trauma, Dissociation, Adult Attachment and Proneness to Hallucinations. AB - BACKGROUND: Childhood adversity, dissociation and adult attachment have all been implicated in the development of hallucinations or 'voice-hearing'. Testing psychological models in relation to subclinical phenomena, such as proneness to hallucinations in non-clinical samples, provides a convenient methodology to develop understanding of the processes and mechanisms underlying clinical symptoms. AIMS: This paper investigates the relative contribution of childhood adversity, dissociation and adult attachment in explaining hallucination proneness in a non-clinical sample. METHODS: Students and staff with no previous contact with secondary care at the University of Manchester were recruited. Participants completed a series of self-report measures: the Launay-Slade Hallucination Scale (LSHS), the Relationship Scale Questionnaire (RSQ), the Childhood Trauma Questionnaire (CTQ), the Dissociative Experiences Schedule (DES II) and the Positive and Negative Affect Schedule (PANAS). RESULTS: As hypothesized, insecure attachment, childhood adversity and dissociative symptoms were correlated with hallucination proneness. Multiple regression analysis, controlling for confounds of age and negative affect, indicated that the RSQ, CTQ and DES II predicted hallucination proneness. Only DES II and RSQ avoidant attachment were significant independent predictors in the final model. CONCLUSIONS: This study provides further evidence to support the idea that attachment and dissociation are important psychological mechanisms involved in voice-hearing proneness. Further testing is required with a clinical population. PMID- 29173210 TI - Psychosocial functioning among regular cannabis users with and without cannabis use disorder. AB - BACKGROUND: In the United States, cannabis accessibility has continued to rise as the perception of its harmfulness has decreased. Only about 30% of regular cannabis users develop cannabis use disorder (CUD), but it is unclear if individuals who use cannabis regularly without ever developing CUD experience notable psychosocial impairment across the lifespan. Therefore, psychosocial functioning was compared across regular cannabis users with or without CUD and a non-user control group during adolescence (age 17; early risk) and young adulthood (ages 18-25; peak CUD prevalence). METHOD: Weekly cannabis users with CUD (n = 311), weekly users without CUD (n = 111), and non-users (n = 996) were identified in the Minnesota Twin Family Study. Groups were compared on alcohol and illicit drug use, psychiatric problems, personality, and social functioning at age 17 and from ages 18 to 25. Self-reported cannabis use and problem use were independently verified using co-twin informant report. RESULTS: In both adolescence and young adulthood, non-CUD users reported significantly higher levels of substance use problems and externalizing behaviors than non-users, but lower levels than CUD users. High agreement between self- and co-twin informant reports confirmed the validity of self-reported cannabis use problems. CONCLUSIONS: Even in the absence of CUD, regular cannabis use was associated with psychosocial impairment in adolescence and young adulthood. However, regular users with CUD endorsed especially high psychiatric comorbidity and psychosocial impairment. The need for early prevention and intervention - regardless of CUD status - was highlighted by the presence of these patterns in adolescence. PMID- 29173212 TI - Substitutions between dairy product subgroups and risk of type 2 diabetes: the Danish Diet, Cancer and Health cohort. AB - The aim of this study was to investigate the associations for specified substitutions between different subgroups of dairy products and the risk of type 2 diabetes. We used data from the Danish Diet, Cancer and Health cohort including 54 277 men and women aged 50-64 years at baseline. Information regarding intake of dairy products was obtained from a validated FFQ, and cases of type 2 diabetes were identified through the Danish National Diabetes Register. Cox proportional hazards regressions were used to estimate associations. During a median follow-up of 15.3 years, 7137 cases were identified. Low-fat yogurt products in place of whole-fat yogurt products were associated with a higher rate of type 2 diabetes (hazard ratio (HR) 1.17; 95 % CI 1.06, 1.29) per serving/d substituted. Whole-fat yogurt products in place of low-fat milk, whole-fat milk or buttermilk were associated with a lower rate of type 2 diabetes (HR 0.89; 95 % CI 0.83, 0.96; HR 0.89; 95 % CI 0.82, 0.96; HR 0.89; 95 % CI 0.81, 0.97; per serving/d substituted, respectively). The pattern of associations was similar when intake was expressed as kJ/d (kcal/d). These findings suggest that intake of whole-fat yogurt products in place of low-fat yogurt products, low-fat milk, whole-fat milk and buttermilk are associated with a lower rate of type 2 diabetes. PMID- 29173213 TI - Evaluation of reference genes for reverse transcription-quantitative PCR assays in organs of zebrafish exposed to glyphosate-based herbicide, Roundup. AB - Roundup is a glyphosate-based herbicide (GBH) widely used in agriculture and may cause toxic effects in non-target organisms. Model organisms, as zebrafish, and analysis of gene expression by reverse transcription-quantitative PCR (RT-qPCR) could be used to better understand the Roundup toxicity. A prerequisite for RT qPCR is the availability of appropriate reference genes; however, they have not been described for Roundup-exposed fish. The aim of this study was to evaluate the expression stability of six reference genes (rpl8, beta-act, gapdh, b2m, ef1alpha, hprt1) and one expressed repetitive element (hatn10) in organs of males (brain, gill, testis) and females (ovary) of zebrafish exposed to Roundup WG at three concentrations (0.065, 0.65 and 6.5 mg N-(phosphonomethyl) glycine/l) for 7 days. Genes were ranked by geNorm, NormFinder, BestKeeper, Delta C t and RefFinder, and their best combinations were determined by geNorm and NormFinder programs. The two most stable ranked genes were specific to each organ: gill (beta-act; rpl8); brain (rpl8; beta-act); testis (ef1alpha; gapdh); and ovary (rpl8; hprt1). The cat transcript level was used to evaluate the effect of normalization with these reference genes. These are the first suitable reference genes described for the analysis of gene expression in organs of Roundup-exposed zebrafish, and will allow investigations of the molecular mechanisms of Roundup toxicity. PMID- 29173214 TI - Appetitive drives for ultra-processed food products and the ability of text warnings to counteract consumption predispositions. AB - OBJECTIVE: The present study aimed to (i) assess the appetitive drives evoked by the visual cues of ultra-processed food and drink products and (ii) investigate whether text warnings reduce appetitive drives and consumers' reported intentions to eat or drink ultra-processed products. DESIGN: In Study I, a well-established psychometric tool was applied to estimate the appetitive drives associated with ultra-processed products using sixty-four image representations. Sixteen product types with four exemplars of a given product were included. Pictures from the International Affective Picture System (IAPS) served as controls. The two exemplars of each product type rated as more appetitive were selected for investigation in the second study. Study II assessed the impact of textual warnings on the appetitive drive towards these thirty-two exemplars. Each participant was exposed to two picture exemplars of the same product type preceded by a text warning or a control text. After viewing each displayed picture, the participants reported their emotional reactions and their intention to consume the product. SETTING: Controlled classroom experiments SUBJECTS: Undergraduate students (Study I: n 215, 135 women; Study II: n 98, 52 women). RESULTS: In Study I, the pictures of ultra-processed products prompted an appetitive motivation associated with the products' nutritional content. In Study II, text warnings were effective in reducing the intention to consume and the appetitive drive evoked by ultra-processed products. CONCLUSIONS: This research provides initial evidence favouring the use of text warnings as a public policy tool to curb the powerful influence of highly appetitive ultra-processed food cues.

AB - OBJECTIVE: Long-chain PUFA (LCPUFA) found in breast milk are derived from dietary sources and critical for optimal infant development. We examined associations between fish consumption and concentrations of LCPUFA and essential n-3 and n-6 fatty acids in breast milk among mothers living around Lake Victoria. DESIGN: We used cross-sectional analyses of associations between recent fish consumption and breast-milk fatty acid concentrations. SETTING: The study was conducted around Lake Victoria on Mfangano Island, Kenya, where multiple fish species are key dietary components and also are widely exported. SUBJECTS: Breast-feeding mothers (n 60) provided breast-milk samples, anthropometric measurements and questionnaire responses. RESULTS: In the previous 3 d, 97 % of women consumed a mean of 178 (sd 111) g fish (~2 servings/3 d). Mean breast-milk concentrations included DHA (0.75 % of total fatty acids), EPA (0.16 %), alpha-linolenic acid (ALA; 0.54 %), arachidonic acid (AA; 0.44 %) and linoleic acid (LA; 12.7 %). Breast-milk DHA concentrations exceeded the global average of 0.32 % in fifty nine of sixty samples. We found native cichlids (Cichlidae) and dagaa (Rastrineobola argentea) contributed high levels of DHA, EPA and AA to local diets. We also found evidence for associations between fish species consumed and breast-milk LCPUFA concentrations when controlling for intake of other fish species, maternal body mass, maternal age, child age and exclusive breast feeding. CONCLUSIONS: The fatty acid composition of breast milk was influenced by the fish species consumed. Ensuring access to diverse fish and particularly inexpensive, locally available species, may be important for diet quality as well as infant growth and development.

PMID- 29173217 TI - Behavioral consequences of mild traumatic brain injury in preschoolers. AB - BACKGROUND: Pediatric traumatic brain injury (TBI) is a leading cause of long term disability in children and adolescents worldwide. Amongst the wide array of consequences known to occur after pediatric TBI, behavioral impairments are among the most widespread and may particularly affect children who sustain injury early in the course of development. The aim of this study was to investigate the presence of internalizing and externalizing behavioral problems 6 months after preschool (i.e. 18-60 months old) mild TBI. METHODS: This work is part of a prospective, longitudinal cohort study of preschool TBI. Participants (N = 229) were recruited to one of three groups: children with mild TBI, typically developing children and orthopedic injured (OI) children. Mothers of children in all three groups completed the Child Behavior Checklist as a measure of behavioral outcomes 6-month post-injury. Demographics, injury-related characteristics, level of parental distress, and estimates of pre-injury behavioral problems were also documented. RESULTS: The three groups did not differ on baseline characteristics (e.g. demographics and pre-injury behavioral problems for the mild TBI and OI groups) and level of parental distress. Mothers' ratings of internalizing and externalizing behaviors were higher in the mild TBI group compared with the two control groups. Pre-injury behavioral problems and maternal distress were found to be significant predictors of outcome. CONCLUSION: Our results show that even in its mildest form, preschool TBI may cause disruption to the immature brain serious enough to result in behavioral changes, which persist for several months post-injury. PMID- 29173218 TI - Improving the implementation of nutrition guidelines in childcare centres improves child dietary intake: findings of a randomised trial of an implementation intervention. AB - OBJECTIVE: Evidence suggests that improvements to the childcare nutrition environment can have a positive impact on child dietary intake. The primary aim of the present study was to assess, relative to usual care, the effectiveness of a multi-strategy implementation intervention in improving childcare compliance with nutrition guidelines. As a secondary aim, the impact on child dietary intake was assessed. DESIGN: Parallel-group, randomised controlled trial design. The 6 month intervention was designed to overcome barriers to implementation of the nutrition guidelines that had been identified by applying the theoretical domains framework. SETTING: Hunter New England region, New South Wales, Australia. SUBJECTS: Forty-five centre-based childcare services. RESULTS: There were no differences between groups in the proportion of services providing food servings (per child) compliant with nutrition guideline recommendations for all five (5/5) food groups at follow-up (i.e. full compliance). Relative to control services, intervention services were more likely to be compliant with guidelines (OR; 95 % CI) in provision of fruit (10.84; 1.19, 551.20; P=0.0024), meat and meat alternatives (8.83; 1.55, -; P=0.023), dairy (8.41; 1.60, 63.62; P=0.006) and discretionary foods (17.83; 2.15, 853.73; P=0.002). Children in intervention services consumed greater servings (adjusted difference; 95 % CI) of fruit (0.41; 0.09, 0.73; P=0.014) and vegetables (0.70; 0.33, 1.08; P<0.001). CONCLUSIONS: Findings indicate that service-level changes to menus in line with dietary guidelines can result in improvements to children's dietary intake. The study provides evidence to advance implementation research in the setting as a means of enhancing child public health nutrition.

PMID- 29173221 TI - Convenience-based food purchase patterns: identification and associations with dietary quality, sociodemographic factors and attitudes. AB - OBJECTIVE: The present study aimed to derive food purchase patterns considering the convenience level of foods. Associations between identified patterns and dietary quality were analysed, as well as household characteristics associated with the dietary patterns. DESIGN: A Convenience Food Classification Scheme (CFCS) was developed. After classifying basic food groups into the CFCS, the formed groups were used to apply a factor analysis to identify convenience-based food purchase patterns. For these patterns nutrient and energy densities were examined. Using regression analysis, associations between the adherence to the patterns and household characteristic and attitude variables were analysed. SUBJECTS: The study used representative German food purchase data from 2011. Approximately 12 million purchases of 13 131 households were recorded in these data. RESULTS: Three convenience-based patterns were identified: a low convenience, a semi-convenience and a ready-to-eat food pattern. Tighter adherence to the semi-convenience pattern was shown to result in the lowest nutrient and highest energy densities. Important factors influencing adherence to the patterns were household size, presence of children and attitudes. Working full-time was negatively associated with adherence to the low-convenience pattern and positively with the ready-to-eat pattern. CONCLUSIONS: Convenience foods were an important part of households' food baskets which in some cases led to lower nutritional quality. Therefore, it is important to offer convenience foods higher in nutrient density and lower in energy density. Interventions targeted on enhancing cooking skills could be an effective strategy to increase purchases of unprocessed foods, which, in turn, could also contribute to an improved diet quality. PMID- 29173220 TI - Manganese influences the expression of fatty acid synthase and malic enzyme in cultured primary chicken hepatocytes. AB - Two experiments were designed to investigate the effects of Mn source and concentration on the mRNA expression and enzymatic activities of fatty acid synthase (FAS) and malic enzyme (ME) in cultured primary broiler hepatocytes. In Expt 1, primary broiler hepatocytes were treated with 0 (control), 0.25, 0.50 or 0.75 mmol/l of Mn as inorganic manganese chloride (MnCl2.4H2O) for 24 and 48 h. In Expt 2, primary broiler hepatocytes were incubated with 0 (control), 0.25 or 0.50 mmol/l of Mn as either manganese chloride or Mn-amino acid chelate for 48 h. The mRNA levels and activities of FAS and ME in the hepatocytes were measured in Expts 1 and 2. The results in Expt 1 showed that only at 48 h mRNA expression levels of FAS and ME in the hepatocytes decreased linearly (P0.33) on any of the measured cellular parameters. The results suggested that Mn might reduce cell damage and regulate FAS and ME expression at a transcriptional level in primary cultured broiler hepatocytes. PMID- 29173222 TI - Maternal conjugated linoleic acid modulates TAG metabolism in adult rat offspring. AB - Conjugated linoleic acid (CLA) might regulate the lipid depots in liver and adipose tissue. As there is an association between maternal nutrition, fat depots and risk of offspring chronic disease, the aim was to investigate the effect of maternal CLA consumption on TAG regulation and some inflammatory parameters in adult male rat offspring receiving or not receiving CLA. Female Wistar rats were fed control (C) or CLA-supplemented (1 %, w/w) diets during 4 weeks before and throughout pregnancy and lactation. After weaning, male offspring of CLA rats were fed C or CLA diets (CLA/C and CLA/CLA groups, respectively), whereas C male rat offspring were fed a C diet (C/C group) for 9 weeks. Serum TAG levels were increased in the CLA/CLA and CLA/C groups, associated with a reduction of lipoprotein lipase activity and weights of adipose tissue. The liver TAG levels were decreased in the CLA/CLA group, related to a significant reduction of fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC) and glucose-6-phosphate dehydrogenase enzyme activities, as well as to the mRNA levels of FAS, ACC, stearoyl-CoA desaturase-1 and sterol regulatory element-binding protein-1c. Even though normal TAG levels were found in the liver of CLA/C rats, a reduction of lipogenesis was also observed. Thus, these results demonstrated a programming effect of CLA on the lipid metabolic pathways leading to a preventive effect on the TAG accretion in adipose tissue and the liver of male rat offspring. This knowledge could be important to develop some dietary strategies leading to a reduced incidence of obesity and fatty acid liver disease in humans. PMID- 29173223 TI - Epidemiology and genetic diversity of human parechoviruses circulating among children hospitalised with acute gastroenteritis in Pune, Western India: a 5 years study. AB - Human parechoviruses (HPeVs) are known to cause various clinical manifestations including acute gastroenteritis. Although HPeV infections and their genotypes have been detected in human patients worldwide, no such reports are available from India to ascertain the association of HPeVs in acute gastroenteritis. The present study was conducted to determine the clinical features and genetic diversity of HPeVs detected in children hospitalised for acute gastroenteritis. Stool specimens (n = 979) collected from children aged ?5 years hospitalised for acute gastroenteritis in Pune, western India during January 2006-December 2010 were included. HPeV RNA was detected by reverse transcription-polymerase chain reaction (RT-PCR) (5'UTR) followed by genotyping using VP1 gene-based PCR and phylogenetic analysis. HPeV was detected in 13.9% (136/979) of the cases, co infections with other enteric viruses were found in 43.4%. HPeV was more frequent in children ?1 year age with infections reported throughout the year. A total of 102/136 (75%) HPeV strains were genotyped, which comprised 13 different HPeV genotypes. Of these, HPeV1 was the most predominant genotype detected and phylogenetically clustered with the Harris strain which is rarely reported. The study documents circulation of heterogeneous HPeV genotypes. Two variant strains of HPeV4 and 'RGD absent' HPeV5 and 6 strains were also detected. This is the first report of HPeV with diversified genotypes identified in acute gastroenteritis patients from India. PMID- 29173224 TI - Occupational therapy for functional neurological disorders: a scoping review and agenda for research. AB - Functional neurological disorders (FND)-also called psychogenic, nonorganic, conversion, and dissociative disorders-constitute one of the commonest problems in neurological practice. An occupational therapist (OT) is commonly involved in management, but there is no specific literature or guidance for these professionals. Classification now emphasizes the importance of positive diagnosis of FND based on physical signs, more than psychological features. Studies of mechanism have produced new clinical and neurobiological ways of thinking about these disorders. Evidence has emerged to support the use of physiotherapy and occupational therapy as part of a multidisciplinary team for functional movement disorders (FMD) and psychotherapy for dissociative (nonepileptic) attacks. The diagnosis and management of FND has entered a new evidence-based era and deserves a standard place in the OT neurological curriculum. We discuss specific management areas relevant to occupational therapy and propose a research agenda. PMID- 29173225 TI - Preventing Respiratory Viral Transmission in Long-Term Care: Knowledge, Attitudes, and Practices of Healthcare Personnel. AB - OBJECTIVE To examine knowledge and attitudes about influenza vaccination and infection prevention practices among healthcare personnel (HCP) in a long-term care (LTC) setting. DESIGN Knowledge, attitudes, and practices (KAP) survey. SETTING An LTC facility in St Louis, Missouri. PARTICIPANTS All HCP working at the LTC facility were eligible to participate, regardless of department or position. Of 170 full- and part-time HCP working at the facility, 73 completed the survey, a 42.9% response rate. RESULTS Most HCP agreed that respiratory viral infections were serious and that hand hygiene and face mask use were protective. However, only 46% could describe the correct transmission-based precautions for an influenza patient. Correctly answering infection prevention knowledge questions did not vary by years of experience but did vary for HCP with more direct patient contact versus less patient contact. Furthermore, 42% of respondents reported working while sick, and 56% reported that their coworkers did. In addition, 54% reported that facility policies made staying home while ill difficult. Some respondents expressed concerns about the safety (22%) and effectiveness (27%) of the influenza vaccine, and 28% of respondents stated that they would not get the influenza vaccine if it was not required. CONCLUSIONS This survey of staff in an LTC facility identified several areas for policy improvement, particularly sick leave, as well as potential targets for interventions to improve infection prevention knowledge and to address HCP concerns about influenza vaccination to improve HCP vaccination rates in LTCs.

AB - This study aimed to evaluate the risk factors for tuberculosis (TB) treatment default in a priority city for disease control in Brazil. A cohort of TB cases diagnosed from 2008 to 2009 was followed up from patients' entry into three outpatient sites, in Juiz de Fora, Minas Gerais (Brazil), until the recording of the outcomes. Drug addiction, alcoholism and treatment site appeared to be independently associated with default. Current users of crack as the hardest drug (odds ratio (OR) 12.25, 95% confidence interval (CI) 3.04-49.26) were more likely to default than other hard drug users (OR 5.67, 95% CI 1.34-24.03), former users (OR 4.12, 95% CI 1.11-15.20) and those not known to use drugs (reference group). Consumers at high risk of alcoholism (OR 2.94, 95% CI 1.08-7.99) and those treated in an outpatient hospital unit (OR 8.22, 95% CI 2.79-24.21%) also were more likely to default. Our results establish that substance abuse was independently associated with default. National TB programmes might be more likely to achieve their control targets if they include interventions aimed at improving adherence and cure rates, by diagnosing and treating substance abuse concurrently with standard TB therapy. PMID- 29173227 TI - Improving nutrition to support healthy ageing: what are the opportunities for intervention? AB - Alongside declining activity levels, energy needs fall in older age and eating less is expected. However, as total food consumption declines, intakes of many nutrients are also likely to fall; while energy requirements may be met, other nutrient needs may not. Although this highlights the importance of nutrient-dense foods and overall diet quality in older age to ensure nutrient intakes are sufficient, maintaining or increasing diet quality may be difficult at a time when food access and preparation are becoming more challenging, and diets may be more monotonous. Poor nutrition, even in developed settings, is common. Older malnourished adults are more likely to have poorer health outcomes, longer hospital stays and increased mortality. Thus, apart from the evident personal costs, the economic burden of disease-related malnutrition is significant, and effective preventive strategies to promote good nutrition among older populations are needed. In particular, there is a need for wider recognition of malnutrition risk among older adults, including implementation of routine screening of nutritional status and early diagnosis. Design of future interventions to support older community-dwelling adults requires a clear understanding of the personal and contextual influences that affect patterns of food choice and consumption, including consideration of the importance of social and psychological factors. In addition, there are opportunities to intervene earlier in the lifecourse; the most effective preventive efforts to promote good nutrition in older age may need to start ahead of age-related changes in physiology and function, including younger adulthood and at the retirement transition.

PMID- 29173229 TI - Prothymosin alpha expression in the vertebrate testis: a comparative review. AB - Prothymosin alpha (PTMA) is a highly acidic, intrinsically disordered protein that was first extracted from rat thymus and characterized as an immunogenic factor but soon detected in a variety of mammalian tissues. The presence of a nuclear localization signal and the adoption of a peculiar random-coil conformation are among the reasons behind its interaction with several molecular partners, hence at this time PTMA is known to be a very conserved and widely expressed molecule, involved in numerous and diverse biological processes. Only few studies have tried to weigh its possible involvement in reproduction, specifically in male gametogenesis: first reports have suggested that PTMA might be associated with the proliferative and early-meiotic phases of mammal spermatogenesis. Some years later, a comparative project on vertebrate spermatogenesis reported the isolation, for the first time, of prothymosin in a non-mammalian species, the amphibian Pelophylax esculentus. PTMA transcript and protein are localized in the germinal compartment, from spermatocytes to spermatozoa. A congruent pattern has been highlighted in studies on the fish Torpedo marmorata and Danio rerio, and in the mammal Rattus norvegicus, in which the expression of PTMA has been found in meiotic and post-meiotic germ cells inside testicular cysts and tubules. Moreover, its presence has been confirmed in rat and human spermatozoa (associated with the acrosome); its retention in the apical region of the head after the acrosome reaction revealed a striking conservation of the pattern during phylogenesis and suggested a possible role for the protein in gametogenesis and in fertilization.

PMID- 29173231 TI - Association between overweight/obesity and eating habits while watching television among primary-school children in the city of Shiraz, Iran. AB - OBJECTIVE: It has been reported that television (TV) viewing is associated with childhood obesity in Western countries. The present study aimed to investigate the relationship between obesity and eating habits while watching TV among primary-school children in the Middle East. DESIGN: Cross-sectional. SETTING: Children were recruited from primary schools of four educational districts in Shiraz, Iran. Anthropometric indices of mass (kg) and height (m) were measured, and BMI (percentile) was calculated. Demographic characteristics, TV viewing behaviours and physical activity data were collected from parents during face-to face interviews and a 3d dietary record was completed. Subject Children (n 607) aged 6-10 years. RESULTS: Mean (sd) age of children was 8.16 (1.37) years, of whom 9.1 and 8.4 % were overweight and obese, respectively. Children who spent >=2 h watching TV on weekdays (OR=1.99; 95 % CI 1.09, 3.60) and weekend days (OR=1.86; 95 % CI 1.01, 3.43) had higher odds of being obese, even after adjusting for physical activity. Children who ate breakfast while watching TV had higher odds of being overweight v. those who did not watch TV while eating breakfast (OR=2.70; 95 % CI 1.02, 7.60). There were no associations between TV viewing during other meals (lunch and dinner) and overweight/obesity. CONCLUSIONS: TV viewing for >=2 h daily increases the risk of being obese in Iranian children aged 6-10 years, independent of physical activity. Further, breakfast consumption while watching TV may increase the risk of overweight/obesity, independent of total TV viewing time. PMID- 29173232 TI - DO IN UTERO SHOCKS HAVE ADVERSE EFFECTS ON CHILD HEALTH OUTCOMES AND CAN WELFARE SCHEMES AMELIORATE SUCH EFFECTS? EVIDENCE FROM ANDHRA PRADESH, INDIA. AB - This study aimed to assess whether shocks experienced by children in the mother's womb can have an adverse effect on their future health, and whether these effects can be ameliorated by government welfare schemes. Data were taken from three phases of the Young Lives Survey carried out in the Indian state of Andhra Pradesh in 2002, 2007 and 2009-2010. Different types of in utero shock were distinguished from the data. Using ordinary least squares (OLS) estimation, it was observed that multiple in utero shocks reduced children's weight-for-age and height-for-age z-scores by 0.07-0.08 and 0.08-0.15 units respectively. The roles of two Indian government welfare schemes - the Midday Meal Scheme (MDMS) and the National Rural Employment Guarantee Scheme (NREGS) - in mitigating the adverse effects of in utero shocks were examined. While the effect of the MDMS was statistically insignificant, that of the NREGS was significant. Although not designed to protect child health, the NREGS has been playing a more effective role than the MDMS in acting as a buffer against the damaging effects of in utero shocks on child health. The study points to the need for greater co-ordination between the two welfare schemes. PMID- 29173233 TI - Fact or fiction: reducing the proportion and impact of false positives. AB - False positive findings in science are inevitable, but are they particularly common in psychology and psychiatry? The evidence that we review suggests that while not restricted to our field, the problem is acute. We describe the concept of researcher 'degrees-of-freedom' to explain how many false-positive findings arise, and how the various strategies of registration, pre-specification, and reporting standards that are being adopted both reduce and make these visible. We review possible benefits and harms of proposed statistical solutions, from tougher requirements for significance, to Bayesian and machine learning approaches to analysis. Finally we consider the organisation and methods for replication and systematic review in psychology and psychiatry. PMID- 29173234 TI - Dietary alpha-lactalbumin induced fatty liver by enhancing nuclear liver X receptor alphabeta/sterol regulatory element-binding protein-1c/PPARgamma expression and minimising PPARalpha/carnitine palmitoyltransferase-1 expression and AMP-activated protein kinase alpha phosphorylation associated with atherogenic dyslipidaemia, insulin resistance and oxidative stress in Balb/c mice. AB - The effect and the role played by dietary alpha-lactalbumin (alpha-LAC) on hepatic fat metabolism are yet to be fully elucidated. We reported previously that alpha-LAC intake induced atherogenic dyslipidaemia in Balb/c mice. The aim of the present study was to investigate if this atherogenic effect could be due to a possible alpha-LAC-induced hepatic steatosis. We examine the ability of dietary alpha-LAC to induce liver steatosis, identifying the molecular mechanisms underlying hepatic lipid metabolism in association with the lipid profile, peripheral insulin resistance (IR) and changes in the hepatic oxidative environment. Male Balb/c mice (n 6) were fed with diets containing either chow or 14 % alpha-LAC for 4 weeks. The alpha-LAC-fed mice developed abdominal adiposity and IR. Moderate liver steatosis with increased TAG and NEFA contents was correlated with atherogenic dyslipidaemia. There was increased nuclear expression of liver X receptor alphabeta (LXRalphabeta), sterol regulatory element-binding protein-1c (SREBP-1c) and PPARgamma transcription factors and of the cytosolic enzymes acetyl-CoA carboxylase 1 (ACC1) and fatty acid synthase involved in the hepatic de novo lipogenesis. The opposite was found for the nuclear receptor PPARalpha and the mitochondrial enzyme carnitine palmitoyltransferase-1 (CPT-1), leading to reduced fatty acid beta-oxidation (FAO). These changes were associated with a significant decrease in both p-Thr172-AMP-activated protein kinase alpha (AMPKalpha) (inactivation) and p-Ser79-ACC1 (activation) and with a more oxidative liver environment increasing lipid peroxidation and protein oxidation and reducing GSH:GSSG ratio in the alpha-LAC-fed mice. In conclusion, 4 weeks of 14 % alpha-LAC feeding induced liver steatosis associated with atherogenic dyslipidaemia, IR and oxidative stress by enhancing nuclear LXRalphabeta/SREBP 1c/PPARgamma expression and diminishing PPARalpha/CPT-1 expression and AMPKalpha phosphorylation shifting the hepatic FAO toward fatty acid synthesis in Balb/c mice.

AB - This study examined the effects of meiosis inhibition during bovine oocyte transportation on developmental competence and quality of produced embryos. The transportation medium was supplemented with: 100 MUM butyrolactone I (BL), 500 MUM IBMX + 100 MUM forskolin (mSPOM), 100 MUM milrinone (MR) or follicular fluid (bFF), and was carried out in a portable incubator for 6 h. Next, oocytes were in vitro matured (IVM) for 18 h, without the meiotic inhibitors, with the exception of mSPOM group, in which was added 20 MUM cilostamide. The three control groups were IVM with 10% fetal calf serum (FCS) (Control Lab FCS) or 0.6% bovine serum albumin (BSA) (Control Lab BSA) in a CO2 in air incubator or in the portable incubator with 0.6% BSA (Control Transp BSA). Higher cleavage rates (P 0.05) to the other groups (23.6 +/- 3.3% to 28.8 +/- 2.7%). The total number of blastomeres was higher (P 0.05) from bFF (67.7 +/- 4.2). No differences (P > 0.05) were found in apoptosis by the activity of caspases (139.0 +/- 3.2 to 152.4 +/- 6.5, expressed in fluorescence intensity) as well as the percentage of TUNEL positive cells (12.3 +/- 2.0% to 15.7 +/- 1.7%). In conclusion, the transportation of oocytes over 6 h with BL, mSPOM or bFF enabled the acquisition of developmental competence at similar rates to the Control Lab FCS group. PMID- 29173236 TI - Attributable Cost of Clostridium difficile Infection in Pediatric Patients. AB - OBJECTIVES The attributable cost of Clostridium difficile infection (CDI) in children is unknown. We sought to determine a national estimate of attributable cost and length of stay (LOS) of CDI occurring during hospitalization in children. DESIGN AND METHODS We analyzed discharge records of patients between 2 and 18 years of age from the Agency for Healthcare Research and Quality (AHRQ) Kids' Inpatient Database. We created a logistic regression model to predict CDI during hospitalization based on demographic and clinical characteristics. Predicted probabilities from the logistic regression model were then used as propensity scores to match 1:2 CDI to non-CDI cases. Charges were converted to costs and compared between patients with CDI and propensity-score-matched controls. In a sensitivity analysis, we adjusted for LOS as a confounder by including it in both the propensity score and a generalized linear model predicting cost. RESULTS We identified 8,527 pediatric hospitalizations (0.53%) with a diagnosis of CDI and 1,597,513 discharges without CDI. In our matched cohorts, the attributable cost of CDI occurring during a hospitalization ranged from $1,917 to $8,317, depending on whether model was adjusted for LOS. When not adjusting for LOS, CDI-associated hospitalizations cost 1.6 times more than non CDI associated hospitalizations. Attributable LOS of CDI was approximately 4 days. CONCLUSIONS Clostridium difficile infection in hospitalized children is associated with an economic burden similar to adult estimates. This finding supports a continued focus on preventing CDI in children as a priority. Pediatric CDI cost analyses should account for LOS as an important confounder of cost.

AB - n-3 PUFA are lipids that play crucial roles in immune-regulation, cardio protection and neurodevelopment. However, little is known about the role that these essential dietary fats play in modulating caecal microbiota composition and the subsequent production of functional metabolites. To investigate this, female C57BL/6 mice were assigned to one of three diets (control (CON), n-3 supplemented (n3+) or n-3 deficient (n3-)) during gestation, following which their male offspring were continued on the same diets for 12 weeks. Caecal content of mothers and offspring were collected for 16S sequencing and metabolic phenotyping. n3- male offspring displayed significantly less % fat mass than n3+ and CON. n-3 Status also induced a number of changes to gut microbiota composition such that n3- offspring had greater abundance of Tenericutes, Anaeroplasma and Coriobacteriaceae. Metabolomics analysis revealed an increase in caecal metabolites involved in energy metabolism in n3+ including alpha ketoglutaric acid, malic acid and fumaric acid. n3- animals displayed significantly reduced acetate, butyrate and total caecal SCFA production. These results demonstrate that dietary n-3 PUFA regulate gut microbiota homoeostasis whereby n-3 deficiency may induce a state of disturbance. Further studies are warranted to examine whether these microbial and metabolic disturbances are causally related to changes in metabolic health outcomes. PMID- 29173238 TI - Toward a Two-Dimensional Model of Social Cognition in Clinical Neuropsychology: A Systematic Review of Factor Structure Studies. AB - OBJECTIVE: Social cognition has received growing interest in many conditions in recent years. However, this construct still suffers from a considerable lack of consensus, especially regarding the dimensions to be studied and the resulting methodology of clinical assessment. Our review aims to clarify the distinctiveness of the dimensions of social cognition. METHOD: Based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statements, a systematic review was conducted to explore the factor structure of social cognition in the adult general and clinical populations. RESULTS: The initial search provided 441 articles published between January 1982 and March 2017. Eleven studies were included, all conducted in psychiatric populations and/or healthy participants. Most studies were in favor of a two-factor solution. Four studies drew a distinction between low-level (e.g., facial emotion/prosody recognition) and high-level (e.g., theory of mind) information processing. Four others reported a distinction between affective (e.g., facial emotion/prosody recognition) and cognitive (e.g., false beliefs) information processing. Interestingly, attributional style was frequently reported as an additional separate factor of social cognition. CONCLUSIONS: Results of factor analyses add further support for the relevance of models differentiating level of information processing (low- vs. high-level) from nature of processed information (affective vs. cognitive). These results add to a significant body of empirical evidence from developmental, clinical research and neuroimaging studies. We argue the relevance of integrating low- versus high-level processing with affective and cognitive processing in a two-dimensional model of social cognition that would be useful for future research and clinical practice.

AB - The purpose of the present study was to reconstruct the phylogeny of dengue virus serotype 4 (DENV-4) that was circulating in Espirito Santo state, Brazil, in 2013 and 2014, and to discuss the epidemiological implications associated with this evolutionary hypothesis. Partial envelope gene of eight DENV-4 samples from Espirito Santo state were sequenced and aligned with 72 worldwide DENV-4 reference sequences from GenBank. A phylogenetic tree was reconstructed through Bayesian Inference and the Time of the Most Recent Common Ancestor was estimated. The study detected the circulation of DENV-4 genotype II in Espirito Santo state, which was closely related to strains from the states of Mato Grosso collected in 2012 and of Sao Paulo sampled in 2015. This cluster emerged around 2011, approximately 4 years after the entry of the genotype II in Brazil through its northern states, possibly imported from Venezuela and Colombia. This is so far the first phylogenetic study of the DENV-4 circulating in Espirito Santo state and shows the importance of an internal route of dengue viral circulation in Brazil to the introduction of the virus into this state.

AB - Superovulatory response is characterized by a high degree of variability and unpredictability. The aim of the present experimental study was to examine whether the amount of maternal body fat can influence the efficiency of ovarian stimulation with gonadotropins. Female mice of two body condition types, normal and obese, produced in a standardized two-generation model, were subjected to ovarian stimulation using eCG and hCG followed by natural mating. Produced ova and embryos were recovered on day 1 and day 4 of pregnancy respectively, and several quantitative, qualitative and developmental parameters were evaluated in them. The overall response of mouse females with normal and elevated amounts of body fat to superovulation was similar: They produced almost the same numbers of ova and embryos on average. Conversely, a higher number of immature oocytes, non fertilized mature oocytes and lower-stage zygotes were collected from fat females. In both groups, the majority of fertilized oocytes was able to cleave and reach the higher stages of development. However, in the group of fat mice, a lower number of blastocysts was collected, and these blastocysts showed increased incidence of apoptotic cell death. In conclusion, although the response of normal and fat mice to superovulatory treatment was similar, the quality and developmental capacities of produced ova were lower in the group of fat donors. PMID- 29173241 TI - X-Ray Excited Optical Luminescence and Portable Electron Probe Microanalyzer Cathodoluminescence (EPMA-CL) Analyzers for On-Line and On-Site Analysis of Nonmetallic Inclusions in Steel. AB - The potential of the application of an X-ray excited optical luminescence (XEOL) analyzer and portable analyzers, composed of a cathodoluminescence (CL) spectrometer and electron probe microanalyzer (EPMA), to the on-line and on-site analysis of nonmetallic inclusions in steel is investigated as the first step leading to their practical use. MgAl2O4 spinel and Al2O3 particles were identified by capturing the luminescence as a result of irradiating X-rays in air on a model sample containing MgAl2O4 spinel and Al2O3 particles in the size range from 20 to 50 MUm. We were able to identify the MgAl2O4 spinel and Al2O3 particles in the same sample using the portable CL spectrometer. In both cases, not all of the particles in the sample were identified because the luminescence intensities of the smaller Al2O3 in particular were too low to detect. These problems could be solved by using an X-ray tube with a higher power and increasing the beam current of the portable CL spectrometer. The portable EPMA distinguished between the MgAl2O4 spinel and Al2O3 particles whose luminescent colors were detected using the portable CL spectrometer. Therefore, XEOL analysis has potential for the on-line analysis of nonmetallic inclusions in steel if we have information on the luminescence colors of the nonmetallic inclusions. In addition, a portable EPMA-CL analyzer would be able to perform on-site analysis of nonmetallic inclusions in steel.

AB - BACKGROUND: Recognition of communicative interactions is a complex social cognitive ability which is associated with a specific neural activity in healthy individuals. However, neural correlates of communicative interaction processing from whole-body motion have not been known in patients with schizophrenia (SCZ). Therefore, the current study aims to examine the neural activity associated with recognition of communicative interactions in SCZ by using displays of the dyadic interactions downgraded to minimalistic point-light presentations. METHODS: Twenty-six healthy controls (HC) and 25 SCZ were asked to judge whether two agents presented only by point-light displays were communicating or acting independently. Task-related activity and functional connectivity of brain structures were examined with General Linear Model and Generalized Psychophysiological Interaction approach, respectively. RESULTS: HC were significantly more efficient in recognizing each type of action than SCZ. At the neural level, the activity of the right posterior superior temporal sulcus (pSTS) was observed to be higher in HC compared with SCZ for communicative v. individual action processing. Importantly, increased connectivity of the right pSTS with structures associated with mentalizing (left pSTS) and mirroring networks (left frontal areas) was observed in HC, but not in SCZ, during the presentation of social interactions. CONCLUSION: Under-recruitment of the right pSTS, a structure known to have a pivotal role in social processing, may also be of importance for higher-order social cognitive deficits in SCZ. Furthermore, decreased task related connectivity of the right pSTS may result in reduced use of additional sources of information (for instance motor resonance signals) during social cognitive processing in schizophrenia. PMID- 29173242 TI - Evidence of multiple intraspecific transmission routes for Leptospira acquisition in Norway rats (Rattus norvegicus). AB - Infectious diseases frequently have multiple potential routes of intraspecific transmission of pathogens within wildlife and other populations. For pathogens causing zoonotic diseases, knowing whether these transmission routes occur in the wild and their relative importance, is critical for understanding maintenance, improving control measures and ultimately preventing human disease. The Norway rat (Rattus norvegicus) is the primary reservoir of leptospirosis in the urban slums of Salvador, Brazil. There is biological evidence for potentially three different transmission routes of leptospire infection occurring in the rodent population. Using newly obtained prevalence data from rodents trapped at an urban slum field site, we present changes in cumulative risk of infection in relation to age-dependent transmission routes to infer which intra-specific transmission routes occur in the wild. We found that a significant proportion of animals leave the nest with infection and that the risk of infection increases throughout the lifetime of Norway rats. We did not observe a significant effect of sexual maturity on the risk of infection. In conclusion, our results suggest that vertical and environmental transmission of leptospirosis both occur in wild populations of Norway rats. PMID- 29173244 TI - Socio-economic variations in the mental health treatment gap for people with anxiety, mood, and substance use disorders: results from the WHO World Mental Health (WMH) surveys. AB - BACKGROUND: The treatment gap between the number of people with mental disorders and the number treated represents a major public health challenge. We examine this gap by socio-economic status (SES; indicated by family income and respondent education) and service sector in a cross-national analysis of community epidemiological survey data. METHODS: Data come from 16 753 respondents with 12 month DSM-IV disorders from community surveys in 25 countries in the WHO World Mental Health Survey Initiative. DSM-IV anxiety, mood, or substance disorders and treatment of these disorders were assessed with the WHO Composite International Diagnostic Interview (CIDI). RESULTS: Only 13.7% of 12-month DSM-IV/CIDI cases in lower-middle-income countries, 22.0% in upper-middle-income countries, and 36.8% in high-income countries received treatment. Highest-SES respondents were somewhat more likely to receive treatment, but this was true mostly for specialty mental health treatment, where the association was positive with education (highest treatment among respondents with the highest education and a weak association of education with treatment among other respondents) but non monotonic with income (somewhat lower treatment rates among middle-income respondents and equivalent among those with high and low incomes). CONCLUSIONS: The modest, but nonetheless stronger, an association of education than income with treatment raises questions about a financial barriers interpretation of the inverse association of SES with treatment, although future within-country analyses that consider contextual factors might document other important specifications. While beyond the scope of this report, such an expanded analysis could have important implications for designing interventions aimed at increasing mental disorder treatment among socio-economically disadvantaged people.

PMID- 29173258 TI - The 1917 Halifax Explosion: the first coordinated local civilian medical response to disaster in Canada. AB - SUMMARY: The 1917 Halifax Explosion was an unfortunate but predictable tragedy, given the sea traffic and munitions cargo, resulting in sudden large-scale damage and catastrophic injuries, with 1950 dead and 8000 injured. Although generous support was received from the United States, the bulk of the medical work was undertaken using local resources through an immediate, massive, centrally coordinated medical response. The incredible care provided 100 years ago by these Canadian physicians, nurses and students is often forgotten, but deserves attention. The local medical response to the 1917 disaster is an early example of coordinated mass casualty relief, the first in Canada, and remains relevant to modern disaster preparedness planning.

PMID- 29173259 TI - Optimizing associated liver partition and portal vein ligation for staged hepatectomy outcomes: Surgical experience or appropriate patient selection? AB - BACKGROUND: Early reports of associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) outcomes have been suboptimal. The literature has confirmed that learning curves influence surgical outcomes. We have 54 months of continuous experience performing ALPPS with strict selection criteria. This study aimed to evaluate the impact of the learning curve on ALPPS outcomes. METHODS: We retrospectively compared patients who underwent ALPPS between April 2012 and March 2016. Patients were grouped into 2 24-month (early and late) periods. All candidates had a high tumour load requiring staged hepatectomy after chemotherapy response, a predicted future liver remnant (FLR) less than 30% and good performance status. RESULTS: Thirty-three patients underwent ALPPS during the study period: 16 in the early group (median age 65 yr, mean body mass index [BMI] 27) and 17 in the late group (median age 60 yr, mean BMI 25). Bilobar disease was comparable in both groups (94% v. 88%, p > 0.99). Duration of surgery was not statistically different. Intraoperative blood loss and need for transfusion were significantly lower in the late group (200 +/- 109 mL v. 100 +/- 43 mL, p < 0.05). The late group had a higher proportion of monosegment ALPPS (4:1). There were no deaths within 90 days in either cohort. Rates of postoperative complications were not statistically significant between groups. The R0 resection rate was similar. The entire 1-year disease-free and overall survival were 52% and 84%, respectively. CONCLUSION: Excellent results can be obtained in innovative complex surgery with careful patient selection and good technical skills. Additionally, the learning curve brought confidence to perform more complex procedures while maintaining good outcomes. PMID- 29173261 TI - The importance of cognitive map placement in bile duct injuries. AB - SUMMARY: Bile duct injuries often occur because of surgeon spatial disorientation. The psychological concept of cognitive map misplacement is a useful explanation of how this disorientation and injury occurs. Surgeons may find that using a "bile duct time out" is a helpful way to orient. Based on the mnemonic B-SAFE, they can use 5 subhepatic landmarks (B, bile duct; S, sulcus of Rouviere; A, hepatic artery; F, umbilical fissure; E, enteric/duodenum) to correctly place their cognitive map. PMID- 29173260 TI - Transanal minimally invasive surgery for benign large rectal polyps and early malignant rectal cancers: experience and outcomes from the first Canadian centre to adopt the technique. AB - BACKGROUND: Transanal minimally invasive surgery (TAMIS) has emerged as a relatively new technique in treating early cancer and benign lesion of the rectum. The technique is likely to be widely adopted, surpassing other comparable techniques owing to its simple setup and cost-effectiveness. We assessed the outcomes of TAMIS at our centre. METHODS: We retrospectively reviewed prospectively collected data on 50 patients who underwent TAMIS for benign, malignant T1 or T2 cancers that were unfit for radical surgery over a 4-year period. Outcomes, including 30-day complications and recurrence, as well as our ability to implement and integrate this technique at our centre were assessed. RESULTS: All 50 TAMIS procedures were successful. The average lesion was 7 cm from the anal verge, the average tumour size was 2.5 cm, the average duration of surgery was 73 minutes, the average length of stay was 1.1 days, and the margin negativity was 84%. Major indications in our series included 25 lesions that were too large for endoscopic resection, 14 early cancers or high-grade dysplasia, 10 margin checks postpolypectomy, 6 cases of recurrent polyposis, and 4 medically unfit patients. There were no deaths. The rate of short-term complications, including rectal bleeding, reoperation and urinary retention, was 16%. The rate of long-term complications, including anal incontinence and stenosis, was 4%. Benign and malignant recurrence rates were 2% and 6%, respectively. Overall long term requirement for invasive procedures, low anterior resection or abdominoperineal resection, was 12%. CONCLUSION: To our knowledge, this is the first Canadian study showing TAMIS to be an efficient and safe procedure for the treatment of well-selected patients with rectal lesions. Outcomes from our centre are comparable with those found in the literature.

PMID- 29173262 TI - Users' guide to the surgical literature: how to assess a noninferiority trial. AB - SUMMARY: A well-planned randomized controlled trial (RCT) is the most optimal study design to determine if a novel surgical intervention is any different than a prevailing one. Traditionally, when we want to show that a new surgical intervention is superior to a standard one, we analyze data from an RCT to see if the null hypothesis of "no difference" can be rejected (i.e., the 2 surgical interventions have the same effect). A noninferiority RCT design seeks to determine whether a new intervention is not worse than a prevailing (standard) one within an acceptable margin of risk or benefit, referred to as the "noninferiority margin." In the last decade, we have observed an increase in the publication of noninferiority RCTs. This article explores this type of study design and discusses the tools that can be used to appraise such a study. PMID- 29173264 TI - Author response.

PMID- 29173267 TI - Treatment effectiveness in interstitial cystitis/bladder pain syndrome: Do patient perceptions align with efficacy-based guidelines? AB - INTRODUCTION: We sought to determine if patients' perceptions of success or failure of interstitial cystitis/bladder pain syndrome (IC/BPS) therapies proposed in treatment guidelines align with the evidence from available clinical trial treatment data. METHODS: A total of 1628 adult females with a self-reported diagnosis of IC completed a web-based survey in which patients described their perceived outcomes with the therapies they were exposed to. Previously published literature, used in part to develop IC/BPS guidelines, provided the clinical trial data outcomes. Patient-reported outcomes were compared to available clinical trial outcomes and published treatment guidelines. RESULTS: Based on patient perceived outcomes (benefit:risk ratio), the most effective treatments were opioids, phenazopyridine, and alkalizing agents, with amitriptyline and antihistamines reported as moderately effective. The only surgical procedure with any effectiveness was electrocautery of Hunner's lesions. In order of efficacy reported in the literature, the therapies for IC/BPS with predicted superior outcomes should be: cyclosporine A, amitriptyline, hyperbaric oxygen, pentosan polysulfate plus subcutaneous heparin, botulinum toxin A plus hydrodistension, and L-arginine. While some of the guideline recommendations aligned with patient reported effectiveness data, there was a general disconnect between guidelines and effectiveness reported in clinical practice. CONCLUSIONS: There is a disconnect between real-world patient perceived effectiveness of IC/BPS treatments compared to the efficacy reported from clinical trial data and subsequent guidelines developed from this efficacy data. Optimal therapy must include the best evidence from clinical research, but should also include real life clinical practice implementation and effectiveness.

PMID- 29173269 TI - Transrectal ultrasound-guided prostate biopsies vs. magnetic resonance imaging ultrasound fusion targeted biopsies: Who are the best candidates? AB - INTRODUCTION: The aim of this study was to compare the results of ultrasound guided prostate biopsies (US-PB) and magnetic resonance imaging-ultrasound fusion biopsies (MRI-PB) in two contemporary cohorts and to describe the parameters orienting the choice of technique. METHODS: Two contemporary cohorts of patients undergoing US-PB or MR-PB using the Urostation(r) (Koelis, Grenoble, France) between November 2010 and July 2015 were analyzed retrospectively. Patients with metastatic cancer or recurrence after treatment, saturation biopsies, and US-PB performed after a negative MRI were excluded. Comparison of populations, biopsy results, and clinical and biological parameters guiding the choice of technique were studied on multivariate analysis (logistic regression) taking into account the following confounding factors: age, prostate-specific antigen (PSA) rate, prostatic volume, number of previous biopsies, and abnormal digital rectal examination. RESULTS: One hundred fourteen patients were included in the US-PB group and 118 in the MR-PB group. Prostate cancer was diagnosed among 65 patients in the US-PB group (detection rate 57.0%) and 70 patients in the MR-PB group (detection rate 59.3%) (odds ratio [OR] 3.00; 95% confidence interval [CI] 1.52 6.17; p=0.002). Among the cancers diagnosed in the MR-PB group, 21 were diagnosed by the two targeted biopsy cores only (15.5%). Patients undergoing MR-PB were significantly younger (p=0.0005), with a higher number of previous biopsy sessions (p<10-7) and larger prostate volume (p=0.001). PSA rate alone (p=0.23) and digital rectal examination (p=0.48) did not significantly interfere with the choice of a technique. CONCLUSIONS: Younger patients with larger prostates and prior negative biopsy were more likely to be offered the MR-PB technique. On multivariate analysis, the detection rate was higher in the MR-PB group. PMID- 29173270 TI - Clinical outcomes of the sequential use of pazopanib followed by everolimus for the treatment of metastatic renal cell carcinoma: A multicentre study in Korea. AB - INTRODUCTION: The aim of this study was to investigate the real-world clinical outcomes of first-line pazopanib and second-line everolimus in Korean patients with metastatic renal cell carcinoma (mRCC). METHODS: Data of patients who had mRCC with clear-cell component between 2001 and 2015 at multiple institutions were collected retrospectively. To be included in the analysis, patients had to meet the following criteria: age >=18 years; received first-line targeted therapy with pazopanib; and received second-line targeted therapy with everolimus. The primary outcomes included overall survival (OS), progression-free survival (PFS), and adverse events (AEs). RESULT: A total of 36 patients were included in the analysis. The median followup period was 33.5 months (range 17-49.5). The median PFS was eight months (95% confidence interval [CI] 6.4-9.6) after treatment with pazopanib and three months (95% CI 1.9-4.1) with everolimus. The median OS was 27 months (95% CI 16.6-37.4). The median treatment duration was seven months (range 4.3-10.8) after treatment with pazopanib and 3.5 months (range 3-4) with everolimus. Multivariate analysis revealed that the Heng risk criteria were independently associated with OS (p<0.001). Almost every patient experienced some form of AE, the majority of which were mostly mild or moderate in severity. The most common AEs were diarrhea (50%), hypertension (44.4%), and fatigue (41.7%) after treatment with pazopanib, and anemia (47.2%), stomatitis (41.7%), and fatigue (38.9%) with everolimus. CONCLUSIONS: The outcomes for the patients treated with pazopanib followed by everolimus in Korea as observed by us were consistent with those reported by previous studies. The Heng risk criteria were significantly associated with the prognosis of patients with mRCC. AEs were mainly mild to moderate and readily managed.

AB - INTRODUCTION: Circumcision is the most common surgical procedure performed by pediatric urologists. Ketorolac has been shown to have an efficacy similar to morphine in multimodal analgesic regimens without the commonly associated adverse effects. Concerns with perioperative bleeding limit the use of ketorolac as an adjunct for pain control in surgical patients. As such, we sought to evaluate our institutional outcomes with respect to ketorolac and postoperative bleeding. METHODS: We retrospectively reviewed all pediatric patients undergoing circumcision from January 1, 2014 to December 31, 2015 at the Alberta Children's Hospital. Demographics, perioperative analgesic regimens, and return to emergency department or clinic for bleeding were gathered through chart review. RESULTS: A total of 475 patients undergoing circumcisions were studied, including 150 (32%) who received perioperative ketorolac and 325 (68%) who received standard analgesia. Patients receiving ketorolac were more likely to return to the emergency department or clinic for bleeding (ketorolac group 19/150 [13%], non ketorolac group 16/325 [5.0%]; p=0.005). Patients receiving ketorolac were more likely to have postoperative sanguineous drainage (ketorolac group 96/150 [64%], non-ketorolac group 150/325 [46%]; p<0.001). There was no significant difference in the number of patients requiring postoperative admission or further medical intervention. CONCLUSIONS: Although a promising analgesic, ketorolac requires additional investigation for safe usage in circumcisions due to possible increased risk of bleeding. PMID- 29173274 TI - Single lower calyceal percutaneous tract combined with flexible nephroscopy: A valuable treatment paradigm for staghorn stones. AB - INTRODUCTION: We evaluated the efficacy and safety of single lower calyceal tract combined with flexible nephroscopy for the management of staghorn renal stones by percutaneous nephrolithotomy. METHODS: The medical records of patients who underwent percutaneous nephrolithotomy for the management of staghorn stones were analyzed. We included patients aged >18 years, while patients with incomplete data and renal anatomical anomalies were excluded from the study. Stone-free rate, postoperative complications, procedure duration, fluoroscopy time, and length of hospitalization were recorded. Postoperative outcomes were evaluated by non-contrast computed tomography scan 4-6 weeks after the operation. Stone-free status was defined as the absence of residual stones >4 mm. RESULTS: The study cohort consisted of 103 consecutive patients. Stone-free rate was 65.0%. No complications were observed in 69.9% of the cases; most postoperative complications were Grade 1 (13.6%) and 2 (10.7%). Five patients (4.9%) suffered a Grade 3a complication and another patient (1.0%) suffered a Grade 3b complication. CONCLUSIONS: Percutaneous nephrolithotomy through a single lower calyceal tract combined with flexible nephroscopy can be a valuable treatment option for the treatment of staghorn calculi, providing efficacy and safety. Nevertheless, the present study is limited by both its retrospective nature and being conducted at a single centre and, thus, proper prospective studies with head-on comparisons are needed to prove or disprove the advantages and disadvantages of either approach.

PMID- 29173276 TI - Do antibiotics decrease prostate-specific antigen levels and reduce the need for prostate biopsy in type IV prostatitis? A systematic literature review. AB - INTRODUCTION: Inflammation of the prostate can be a cause of elevated prostate specific antigen (PSA) in men referred for suspected prostate cancer. This systematic review assesses the evidence for antibiotic therapy in patients with type IV (asymptomatic) prostatitis with regard to reduction of PSA levels and discrimination between prostate cancer and inflammation. METHODS: MEDLINE, EMBASE, and the Cochrane registry were searched for papers reporting on cohorts of men with elevated PSA and type IV prostatitis that were treated with antibiotics. RESULTS: The search yielded 160 papers, of which 11 met the inclusion criteria: two randomized trials and nine cohort studies. In total, the studies reported on 1011 patients with type IV prostatitis, of whom 926 were treated with antibiotics. PSA normalization was seen after antibiotic treatment in 33.2% of patients (95% confidence interval [CI] 24.9-42.8). Meta-analysis of the randomized trials did not demonstrate a higher likelihood of PSA normalization in the antibiotics arm as compared to the control arm (odds ratio [OR] 1.27; 95% CI 0.58-2.76; p=0.553). Four studies performed prostate biopsies in all patients. Although three of these studies demonstrated lower prevalence of prostate cancer in patients in whom PSA had normalized, meta-analysis failed to show a statistically significant difference (OR 0.39; 95% CI 0.06-2.49; p=0.319). CONCLUSIONS: The available evidence does not support antibiotic therapy for differentiation between benign and malignant cause of elevated PSA in men with type IV prostatitis. PMID- 29173277 TI - Exogenous tumor necrosis factor-alpha could induce egress of Toxoplasma gondii from human foreskin fibroblast cells. AB - Toxoplasma gondii is an intra-cellular protozoan parasite that can infect almost all nucleated cells, eliciting host immune responses against infection. Host tissue damage is mainly caused by cellular lysis when T. gondii egresses from infected cells. However, the effects of cytokines released by host immune cells on egression of T. gondii remain elusive. This study aimed to investigate the role of tumor necrosis factor-alpha (TNF-alpha) on the egress of T. gondii from infected human foreskin fibroblast (HFF) cells and to elucidate the underlying mechanisms that regulate TNF-alpha-induced egress. Using flow cytometry to count tachyzoites of T. gondii released into cell culture medium, we found that egress of T. gondii from infected HFF cells could be induced by 10 ng/mL TNF-alpha in a time-dependent manner. Pre-treatment of infected HFF cells with BAPTA-AM to chelate intra-parasitic calcium could greatly inhibit TNF-alpha-induced egress. Similar results were obtained when using cytochalasin D to block parasite motility before the TNF-alpha-induced egress assay. In addition, blocking host apoptosis by Z-VAD-FMK could decrease TNF-alpha induced egress, while blocking necroptosis by necrostatin-1 has little impact on TNF-alpha-induced egress. The egressed tachyzoites displayed a normal growth rate and lost no virulence. Our results suggest that host cytokines could influence the cellular lytic processes of T. gondii, providing new insights into the relationship between host TNF-alpha and T. gondii pathogenesis. PMID- 29173278 TI - Comparison of the in vitro anthelmintic effects of Acacia nilotica and Acacia raddiana. AB - Gastrointestinal nematodes are a major threat to small ruminant rearing in the Sahel area, where farmers traditionally use bioactive plants to control these worms, including Acacia nilotica and Acacia raddiana. The main aim of this study was to screen the potential anthelmintic properties of aqueous and acetone extracts of leaves of these two plants based on three in vitro assays: (1) the egg hatch inhibition assay (EHA); (2) the larvae exsheathment inhibition assay (LEIA) using Haemonchus contortus as a model; and (3) an adult mortality test (AMT) applied on Caenorhabditis elegans. For the EHA, only A. raddiana was effective with IC50 = 1.58 mg/mL for aqueous extract, and IC50 = 0.58 mg/mL for acetonic extract. For the LEIA, all extracts inhibited the exsheathment of larvae compared to the controls, and the aqueous extract of A. nilotica was more larvicidal with IC50 = 0.195 mg/mL. In general, all responses to the substances were dose-dependent and were significantly different from the control group (p < 0.05). For the AMT, the extracts of the two Acacia species were effective but A. raddiana showed greater efficacy with 100% mortality at 2.5 mg/mL and LC50 = 0.84 mg/mL (acetonic extract). The addition of polyvinyl polypyrrolidone (PVPP) to the extracts suggested that tannins were responsible for blocking egg eclosion and inducing adult mortality but were not responsible for exsheathment inhibition. These results suggest that the leaves of these Acacia species possess ovicidal and larvicidal activities in vitro against H. contortus, and adulticidal effects against C. elegans.

PMID- 29173280 TI - Predicting non-linear dynamics by stable local learning in a recurrent spiking neural network. AB - The brain needs to predict how the body reacts to motor commands, but how a network of spiking neurons can learn non-linear body dynamics using local, online and stable learning rules is unclear. Here, we present a supervised learning scheme for the feedforward and recurrent connections in a network of heterogeneous spiking neurons. The error in the output is fed back through fixed random connections with a negative gain, causing the network to follow the desired dynamics. The rule for Feedback-based Online Local Learning Of Weights (FOLLOW) is local in the sense that weight changes depend on the presynaptic activity and the error signal projected onto the postsynaptic neuron. We provide examples of learning linear, non-linear and chaotic dynamics, as well as the dynamics of a two-link arm. Under reasonable approximations, we show, using the Lyapunov method, that FOLLOW learning is uniformly stable, with the error going to zero asymptotically.

METHODS: A hospitalwide, opt-out TTS with three full time certified counselors was developed in a large tertiary care hospital to proactively treat smokers according to Chronic Care Model principles and national treatment guidelines. A bioinformatics platform facilitated integration into the electronic health record to meet evolving Centers for Medicare & Medicaid Services meaningful use and Joint Commission standards. TTS counselors visited smokers at the bedside and offered counseling, recommended smoking cessation medication to be ordered by the primary clinical service, and arranged for postdischarge resources. RESULTS: During a 3.5-year span, 21,229 smokers (31,778 admissions) were identified; TTS specialists reached 37.4% (7,943), and 33.3% (5,888) of daily smokers received a smoking cessation medication order. Adjusted odds ratios (AORs) of receiving a chart order for smoking cessation medication during the hospital stay and at discharge were higher among patients the TTS counseled > 3 minutes and recommended medication: inpatient AOR = 7.15 (95% confidence interval [CI] = 6.59-7.75); discharge AOR = 5.3 (95% CI = 4.71-5.97). As implementation progressed, TTS counseling reach and medication orders increased. To assess smoking status <= 1 month postdischarge, three methods were piloted, all of which were limited by low follow-up rates (4.5%-28.6%). CONCLUSION: The TTS counseled approximately 3,000 patients annually, with increases over time for reach and implementation. Remaining challenges include the development of strategies to engage inpatient care teams to follow TTS recommendations, and patients postdischarge in order to optimize postdischarge smoking cessation. PMID- 29173283 TI - Using Lean Quality Improvement Tools to Increase Delivery of Evidence-Based Tobacco Use Treatment in Hospitalized Neurosurgical Patients. AB - BACKGROUND: Health care providers routinely undertreat tobacco dependence, indicating a need for innovative ways to increase delivery of evidence-based care. Lean, a set of quality improvement (QI) tools used increasingly in health care, can help streamline processes, create buy-in for use of evidence-based practices, and lead to the identification of solutions on the basis of a problem's root causes. To date, no published research has examined the use of Lean tools in tobacco dependence. A 12-month QI project using Lean tools was conducted to increase delivery of evidence-based tobacco use treatment (TUT) to hospitalized neurosurgical patients. METHODS: The study team developed a nicotine replacement therapy (NRT) and counseling protocol for neurosurgery inpatients who indicated current tobacco use and used Lean tools to increase protocol adherence. Rates of NRT prescription, referrals to counseling, and follow-up phone calls were compared pre- and postintervention. Secondary measures included patient satisfaction with intervention, quit rates, and reduction rates at 4 weeks postdischarge. RESULTS: Referrals to counseling doubled from 31.7% at baseline to 62.0% after implementation of the intervention, and rates of nicotine replacement therapy (NRT) prescriptions during hospitalization and at discharge increased from 15.3% to 28.5% and 9.0% to 19.3%, respectively. Follow-up phone call rates also dramatically increased. The majority of satisfaction survey respondents indicated that counseling had a positive or neutral impact on stress level and overall satisfaction. CONCLUSION: Lean tools can dramatically increase use of evidence-based TUT in hospitalized patients. This project is easily replicable by professionals seeking to improve delivery of tobacco treatment. These findings may be particularly helpful to inpatient surgical departments that have traditionally been reticent to prescribe NRT. PMID- 29173281 TI - AKT isoforms have distinct hippocampal expression and roles in synaptic plasticity. AB - AKT is a kinase regulating numerous cellular processes in the brain, and mutations in AKT are known to affect brain function. AKT is indirectly implicated in synaptic plasticity, but its direct role has not been studied. Moreover, three highly related AKT isoforms are expressed in the brain, but their individual roles are poorly understood. We find in Mus musculus, each AKT isoform has a unique expression pattern in the hippocampus, with AKT1 and AKT3 primarily in neurons but displaying local differences, while AKT2 is in astrocytes. We also find isoform-specific roles for AKT in multiple paradigms of hippocampal synaptic plasticity in area CA1. AKT1, but not AKT2 or AKT3, is required for L-LTP through regulating activity-induced protein synthesis. Interestingly, AKT activity inhibits mGluR-LTD, with overlapping functions for AKT1 and AKT3. In summary, our studies identify distinct expression patterns and roles in synaptic plasticity for AKT isoforms in the hippocampus. PMID- 29173284 TI - Development of Patient-Centered Disability Status Questions to Address Equity in Care. AB - BACKGROUND: Patients with disabilities experience disparities in accessing and receiving high-quality health care services as compared to patients without disabilities. To address the disparities, health care organizations need to identify which of their patients have disabilities to track quality of care and provide appropriate health care accommodations. To date, no evidence-based sets of disability questions exist that serve these purposes. A study was conducted to identify patient-centered disability questions for health care organizations to determine which patients require health care accommodations and to track the quality of care experienced by patients with disabilities. METHODS: In the first of three phases, a focus group with patients and caregivers (N = 54) and interviews with providers (N = 15) were conducted to explore the disability questions that they believed were important. In the second phase, nationally recognized experts (N = 17) participated in a modified Delphi panel to develop a set of disability questions. The third phase entailed cognitive interviews (N = 46) with patients with and without disabilities to refine the wording of the disability questions identified through the previous rounds. RESULTS: Through the three phases, six essential questions and three additional recommended questions were identified. Questions addressed hearing, visual, motor, cognitive, communication, and learning disabilities, and the ability to conduct activities of daily living. An overall question for disabilities not included in the previous questions was also identified. CONCLUSION: Through a rigorous, three stage process that engaged multiple stakeholders, patient-centered disability questions were identified for health care organizations to use to identify disparities within their organizations and accommodations that address these disparities. PMID- 29173285 TI - Expanding the Scope of the Rapid Response System. PMID- 29173286 TI - An Airway Rapid Response System: Implementation and Utilization in a Large Academic Trauma Center. AB - BACKGROUND: Rapid response teams mobilize resources to patients experiencing acute deterioration. Failed airway management results in death or anoxic brain injury. A codified, systems-based approach to bring personnel and equipment to the bedside for multidisciplinary airway assessment and rescue was reflected in the initial implementation of an airway rapid response (ARR) team. METHODS: A retrospective review of records of 117 ARR events in a 40-month period (August 2011-November 2014) was undertaken at the Hospital of the University of Pennsylvania, a 789-bed, academic, urban, tertiary care, Level 1 trauma center. RESULTS: Of the 117 ARR events, 60 (51.3%) were called in the ICU, and 43 (36.8%) in the general ward. A definitive airway was secured in all patients for whom airway management was attempted. A new surgical airway was performed in five of the patients. Seven patients went to the operating room for airway management. Nine patients died or had care withdrawn shortly after the ARR. CONCLUSION: Difficult airway emergencies represent a small but critical element of airway rescue scenarios. Before the implementation of the ARR system, the process to bring the right team, equipment, expertise, and consensus on the right actions to critical airway emergencies was ad hoc. ARR activation, which brings multidisciplinary airway consultation, expert skills, and advanced airway equipment to the bedside, contributed to definitive airway management for surgical and nonsurgical airways. Performance of a bedside emergency surgical airway was uncommon. The ARR system represents a significant enhancement of the "anesthesia stat" system that typifies the airway emergency system at many institutions.

AB - OBJECTIVE: To describe the prevalence of obesity as estimated by waist circumference (WC) and body mass index (BMI) and compare associations of WC and BMI with indicators of metabolic, cardiovascular, and renal health in children with chronic kidney disease (CKD). STUDY DESIGN: Cross-sectional analysis stratified by CKD etiology (nonglomerular or glomerular) of 737 subjects. The kappa statistic was used to assess agreement between the 2 measures of obesity. Linear regression models were performed using WC and BMI as separate independent variables. Dependent variables included lipid measures, insulin resistance, blood pressure, left ventricular mass index, proteinuria, and estimated glomerular filtration rate. Associations were scaled to SD and interpreted as the change in dependent variable associated with a 1-SD change in WC or BMI. RESULTS: There was good agreement (kappa statistic = 0.68) between WC and BMI in identifying obesity. Approximately 10% of subjects had obesity by 1 measure but not the other. BMI was more strongly associated with estimated glomerular filtration rate than WC. BMI was more strongly associated with left ventricular mass index in the nonglomerular CKD group compared with WC, but both had significant associations. The associations between WC and BMI with the remainder of the dependent variables were not significantly different. CONCLUSIONS: Measurement of WC added limited information to BMI in this cohort. Further longitudinal study is needed to determine how WC and BMI compare in predicting outcomes, particularly for children with CKD identified as having obesity by 1 measure but not the other. PMID- 29173297 TI - The Clinical Utility and Safety of a New Strategy for the Treatment of Refractory Kawasaki Disease. AB - OBJECTIVE: To assess the clinical utility and safety of a strategy for refractory Kawasaki disease, defined by Egami score >=3. STUDY DESIGN: First-line treatment was with intravenous methylprednisolone (30 mg/kg, 2 hours, 1 dose) plus intravenous immunoglobulin (2 g/kg, 24 hours) treatment. Patients resistant to first-line treatment received additional intravenous immunoglobulin as a second line treatment. Patients resistant to second-line treatment who had received Bacillus Calmette-Guerin vaccination 6 months earlier were treated with infliximab; otherwise, plasma exchange was performed. A total of 71 refractory patients with Kawasaki disease (median age: 2.4 years) of 365 patients with Kawasaki disease were treated according to our strategy from April 2007 to April 2016. Treatment resistance was defined as a persistent fever at 36 hours after treatment. We evaluated coronary artery lesions at the time of the diagnosis, at 1 month, and at 1 year after the diagnosis in accordance with the American Heart Association guidelines and the criteria of the Japanese Ministry of Health, Labour, and Welfare. RESULTS: First-line therapy was effective for 58 of 71 patients (81.6%), and second-line therapy was effective for 9 of 13 patients (69.2%). At third line, 3 patients were treated by infliximab, and 1 was treated with plasma exchange. Of the 18 patients with coronary artery abnormalities at diagnosis, 13 patients at 1 month and 6 patients at 1 year had coronary artery dilatation (median z score 3.0, 2.6, and 1.4, respectively). There were no patients with coronary artery aneurysm (CAA). CONCLUSIONS: Our strategy for refractory Kawasaki disease was safe and effective in preventing CAA. PMID- 29173298 TI - Management of Congenital Heart Disease Associated with Ellis-van Creveld Short rib Thoracic Dysplasia. AB - OBJECTIVE: To evaluate clinical outcome of patients with Ellis-van Creveld syndrome (EVC) in whom congenital heart disease (CHD) repair was delayed intentionally to reduce the risk of postoperative respiratory morbidity and mortality. STUDY DESIGN: This retrospective review of 51 EVC c.1886+5G>T homozygotes born between 2005 and 2014 focused on 18 subjects who underwent surgery for CHD, subdivided into early (mean, 1.3 months) vs delayed (mean, 50.1 months) repair. RESULTS: Growth trajectories differed between control subjects and patients with EVC, and CHD was associated with slower weight gain. Relative to controls, infants with EVC had a 40%-75% higher respiratory rates (independent of CHD) accompanied by signs of compensated respiratory acidosis. Blood gases and respiratory rates approached normal values by age 4 years. Hemodynamically significant CHD was present in 23 children, 18 (78%) of whom underwent surgical repair. Surgery was performed at 1.3 +/- 1.3 months for children born between 2005 and 2009 (n = 9) and 50.1 +/- 40.2 months (P = .009) for children born between 2010 and 2014 (n = 9). The latter had shorter postoperative mechanical ventilation (1.1 +/- 2.4 days vs 49.6 +/- 57.1 days; P = .075), shorter intensive care duration of stay (16 +/- 24 days vs 48.6 +/- 44.2 days; P = .155), and no postoperative tracheostomies (vs 60%; P = .028) or deaths (vs 44%; P = .082). CONCLUSION: Among children with EVC and possibly other short-rib thoracic dysplasias, delayed surgical repair of CHD reduces postoperative morbidity and improves survival. Respiratory rate serves as a simple indicator for optimal timing of surgical repair.

PMID- 29173300 TI - Persistent High Non-High-Density Lipoprotein Cholesterol in Early Childhood: A Latent Class Growth Model Analysis. AB - OBJECTIVES: To examine patterns of non-high-density lipoprotein (HDL) cholesterol in early childhood and identify factors associated with persistent high non-HDL cholesterol in healthy urban children. STUDY DESIGN: We identified all children enrolled in a primary care practice-based research network called TARGet Kids! (The Applied Research Group for Kids) with >=3 laboratory measurements of non-HDL cholesterol. Latent class growth model analysis was performed to identify distinct trajectory groups for non-HDL cholesterol. Trajectory groups were then categorized into "normal" vs "persistent-high" non-HDL cholesterol based on guideline cut-off values and logistic regression was completed to examine the association between trajectory group and the presence of anthropometric and cardiometabolic risk factors. RESULTS: A total of 608 children met inclusion criteria for the trajectory analysis (median age at enrolment = 18.3, IQR = 27.9 months). Four trajectory groups were identified with 2 groups (n = 451) categorized as normal non-HDL cholesterol and 2 groups (n = 157) as persistent high non-HDL cholesterol. Family history of high cholesterol (OR 2.04, 95% CI 1.27-3.28) was associated significantly with persistent high non-HDL cholesterol, whereas East/Southeast Asian vs European ethnicity (OR 0.33, 95% CI 0.14-0.78), longer breastfeeding duration (OR 0.96, 95% CI 0.93-1.00), and greater birth weight (OR 0.69, 95% CI 0.48-1.00) were associated with lower odds of persistent high non-HDL cholesterol. CONCLUSIONS: Patterns of non-HDL cholesterol are identified during early childhood, and family history of high cholesterol was associated most strongly with persistent high non-HDL cholesterol. Future research should inform the development of a clinical prediction tool for lipids in early childhood to identify children who may benefit from interventions to promote cardiovascular health.

PMID- 29173301 TI - Targeted Gene Next-Generation Sequencing in Chinese Children with Chronic Pancreatitis and Acute Recurrent Pancreatitis. AB - OBJECTIVE: To identify causal mutations in certain genes in children with acute recurrent pancreatitis (ARP) or chronic pancreatitis (CP). STUDY DESIGN: After patients were enrolled (CP, 55; ARP, 14) and their clinical characteristics were investigated, we performed next-generation sequencing to detect nucleotide variations among the following 10 genes: cationic trypsinogen protease serine 1 (PRSS1), serine protease inhibitor, Kazal type 1 (SPINK1), cystic fibrosis transmembrane conductance regulator gene (CFTR), chymotrypsin C (CTRC), calcium sensing receptor (CASR), cathepsin B (CTSB), keratin 8 (KRT8), CLAUDIN 2 (CLDN2), carboxypeptidase A1 (CPA1), and ATPase type 8B member 1 (ATP8B1). Mutations were searched against online databases to obtain information on the cause of the diseases. Certain novel mutations were analyzed using the SIFT2 and Polyphen-2 to predict the effect on protein function. RESULTS: There were 45 patients with CP and 10 patients with ARP who harbored 1 or more mutations in these genes; 45 patients had at least 1 mutation related to pancreatitis. Mutations were observed in the PRSS1, SPINK1, and CFTR genes in 17 patients, the CASR gene in 5 patients, and the CTSB, CTRC, and KRT8 genes in 1 patient. Mutations were not found in the CLDN, CPA1, or ATP8B1 genes. We found that mutations in SPINK1 may increase the risk of pancreatic duct stones (OR, 11.07; P = .003). The patients with CFTR mutations had a higher level of serum amylase (316.0 U/L vs 92.5 U/L; P = .026). CONCLUSION: Mutations, especially those in PRSS1, SPINK1, and CFTR, accounted for the major etiologies in Chinese children with CP or ARP. Children presenting mutations in the SPINK1 gene may have a higher risk of developing pancreatic duct stones. PMID- 29173303 TI - Are We Using Abdominal Radiographs Appropriately in the Management of Pediatric Constipation? AB - OBJECTIVE: To identify the reasons why pediatric gastroenterologists obtain abdominal radiographs in the management of pediatric constipation. STUDY DESIGN: This was a prospective study surveying providers regarding their rationale, interpretation, resultant change, and confidence in their management before and after obtaining KUBs in patients seen for suspected constipation. Demographics and clinical findings were obtained from medical records. RESULTS: A total of 24 providers were surveyed after 72 patient encounters. Reasons for obtaining an abdominal radiograph included evaluation of stool burden (70%), need for a clean out (35%), fecal impaction (27%), cause of abdominal pain (24%), demonstration of stool burden to families (14%), assessment of response to therapy (13%), or encopresis (10%). The plan was changed in 47.6% of cases based on radiographic findings. In cases in which a plan was outlined before obtaining the radiograph (69%), the initial plan was implemented on average in 52.5%. In cases with no plans before obtaining the radiograph, previously unconsidered plans were implemented in 8.7%. Provider confidence in the management plan increased from 2.4 +/- 2.7 to 4.1 +/- 1.8 (P < .05) after the abdominal radiograph. CONCLUSION: Abdominal radiographs commonly are obtained by pediatric gastroenterologists in the evaluation and management of constipation. The majority used it to make a diagnosis, and nearly one-half changed their management based on the imaging findings. Overall, they reported an improved confidence in their management plan, despite evidence that radiographic findings poorly correlate with clinical severity. This study highlights the need for further provider education regarding the recommendations delineated in existing constipation guidelines. PMID- 29173304 TI - Randomized Trial of Dexamethasone Versus Prednisone for Children with Acute Asthma Exacerbations. AB - OBJECTIVE: To determine whether 2 doses of dexamethasone is as effective as 5 days of prednisolone/prednisone therapy in improving symptoms and quality of life of children with asthma exacerbations admitted to the emergency department (ED). STUDY DESIGN: We conducted a randomized, noninferiority trial including patients aged 1-14 years who presented to the ED with acute asthma to compare the efficacy of 2 doses of dexamethasone (0.6 mg/kg/dose, experimental treatment) vs a 5-day course of prednisolone/prednisone (1.5 mg/kg/d, followed by 1 mg/kg/d on days 2 5, conventional treatment). Two follow-up telephone interviews were completed at 7 and 15 days. The primary outcome measures were the percentage of patients with asthma symptoms and quality of life at day 7. Secondary outcomes were unscheduled returns, admissions, adherence, and vomiting. RESULTS: During the study period, 710 children who met the inclusion criteria were invited to participate and 590 agreed. Primary outcome data were available in 557 patients. At day 7, experimental and conventional groups did not show differences related to persistence of symptoms (56.6%, 95% CI 50.6-62.6 vs 58.3%, 95% CI 52.3-64.2, respectively), quality of life score (80.0 vs 77.7, not significant [ns]), admission rate (23.9% vs 21.7%, ns), unscheduled ED return visits (4.6% vs 3.3%, ns), and vomiting (2.1% vs 4.4%, ns). Adherence was greater in the dexamethasone group (99.3% vs 96.0%, P < .05). CONCLUSION: Two doses of dexamethasone may be an effective alternative to a 5-day course of prednisone/prednisolone for asthma exacerbations, as measured by persistence of symptoms and quality of life at day 7. CLINICAL TRIAL REGISTRATION: clinicaltrialsregister.eu: 2013-003145-42. PMID- 29173306 TI - Sex in journals. PMID- 29173305 TI - Epilepsy or a Seizure Disorder? Parental Knowledge and Misconceptions About Terminology. AB - OBJECTIVE: To assess primary caregiver understanding of the term epilepsy. STUDY DESIGN: A cross-sectional telephone survey evaluated understanding of the term epilepsy among primary caregivers of children diagnosed with epilepsy at an urban referral center during a 24-month period. Three measures of primary caregiver understanding were used: (1) identifying if their child had a seizure disorder, epilepsy, or both; (2) providing an open-ended definition of epilepsy; and (3) selecting from a multiple-choice definition of epilepsy. Caregivers with 3 correct answers were assigned the greatest knowledge score. Associations with possible predictor variables were analyzed. RESULTS: Caregivers for 75 of 116 eligible patients were contacted successfully. Of those, 55 of 75 met eligibility criteria; 45 of the eligible caregivers completed the survey. Twenty-six of 45 caregivers (58%) identified that their child had both a seizure disorder and epilepsy, 5 of 45 (11%) provided a correct open-ended definition of epilepsy, and 16 of 45 (36%) selected the correct multiple-choice definition. Fifteen caregivers (33%) had no correct answers. Seventeen (38%) answered 1, 9 (20%) answered 2, and 4 (9%) answered all 3 measures correctly. Caregivers with greater self-rated understanding had greater epilepsy knowledge scores (P = .008). Having a child neurologist as the first person to discuss the diagnosis with the caregiver also predicted a greater epilepsy knowledge score (P = .04). CONCLUSIONS: Most primary caregivers of children with epilepsy have a poor understanding of the term epilepsy. Changes are needed in how we educate caregivers about the meaning of this term. PMID- 29173307 TI - Chronic pulmonary insufficiency of prematurity: definitions matter. PMID- 29173308 TI - Shared Reading Quality and Brain Activation during Story Listening in Preschool Age Children. AB - OBJECTIVE: To explore the relationship between maternal shared reading quality (verbal interactivity and engagement) and brain function during story listening in at-risk, preschool-age children, in the context of behavioral evidence and American Academy of Pediatrics, recommendations. STUDY DESIGN: In this cross sectional study, 22 healthy, 4-year-old girls from low socioeconomic status households completed functional magnetic resonance imaging using an established story listening task, followed by videotaped observation of uncoached mother daughter reading of the same, age-appropriate picture book. Shared reading quality was independently scored applying dialogic reading and other evidence based criteria reflecting interactivity and engagement, and applied as a predictor of neural activation during the functional magnetic resonance imaging task, controlling for income and maternal education. RESULTS: Shared reading quality scores were generally low and negatively correlated with maternal distraction by smartphones (P < .05). Scores were positively correlated with activation in left-sided brain areas supporting expressive and complex language, social-emotional integration, and working memory (P <.05, false discovery rate corrected). CONCLUSIONS: Maternal shared reading quality is positively correlated with brain activation supporting complex language, executive function, and social emotional processing in at-risk, preschool-age children. These findings represent novel neural biomarkers of how this modifiable aspect of home reading environment may influence foundational emergent literacy skills, reinforce behavioral evidence and American Academy of Pediatrics, recommendations, and underscore the potential of dialogic reading interventions to promote healthy brain development, especially in at-risk households. PMID- 29173309 TI - Delirium in Hospitalized Children with Cancer: Incidence and Associated Risk Factors. AB - OBJECTIVE: To assess the incidence of delirium and its risk factors in hospitalized children with cancer. STUDY DESIGN: In this cohort study, all consecutive admissions to a pediatric cancer service over a 3-month period were prospectively screened for delirium twice daily throughout their hospitalization. Demographic and treatment-related data were collected from the medical record after discharge. RESULTS: A total of 319 consecutive admissions, including 186 patients and 2731 hospital days, were included. Delirium was diagnosed in 35 patients, for an incidence of 18.8%. Risk factors independently associated with the development of delirium included age <5 years (OR = 2.6, P = .026), brain tumor (OR = 4.7, P = .026); postoperative status (OR = 3.3, P = .014), and receipt of benzodiazepines (OR = 3.7,P < .001). Delirium was associated with increased hospital length of stay, with median length of stay for delirious patients of 10 days compared with 5 days for patients who were not delirious during their hospitalization (P < .001). CONCLUSIONS: In this cohort, delirium was a frequent complication during admissions for childhood cancer, and was associated with increased hospital length of stay. Multi-institutional prospective studies are warranted to further characterize delirium in this high risk population and identify modifiable risk factors to improve the care provided to hospitalized children with cancer. PMID- 29173310 TI - The Effectiveness of Trivalent Inactivated Influenza Vaccine in Children with Acute Leukemia. AB - OBJECTIVE: The objective of this study was to determine the effectiveness of trivalent inactivated influenza vaccine (TIV) for the prevention of laboratory confirmed influenza and influenza-like illnesses (ILI) among children and adolescents receiving therapy for acute leukemia. STUDY DESIGN: A retrospective review of the demographic and clinical characteristics of 498 patients at a pediatric cancer center who received therapy for acute leukemia during 3 successive influenza seasons (2010-2011 through 2012-2013). RESULTS: In 498 patient seasons with a known immunization history (median age, 6 years; range, 1 21), 354 patients (71.1%) were immunized with TIV and 98 (19.7%) received a booster dose of vaccine. Vaccinated and unvaccinated patients had generally similar demographic characteristics. There were no differences in the overall rates of influenza or ILI between vaccinated and unvaccinated patients overall, or in any individual season. There was no difference in the rates of influenza or ILI between patients who received 1 dose of vaccine and those who received 2 doses. Time to first influenza infection and time to first ILI in vaccinated and unvaccinated patients were not different. CONCLUSION: TIV did not protect children and adolescents with acute leukemia against laboratory-confirmed influenza or ILI. Future prospective studies should assess TIV effectiveness in high-risk subpopulations and alternative strategies to prevent influenza should be considered in this population. PMID- 29173311 TI - Predicting Mortality or Intestinal Failure in Infants with Surgical Necrotizing Enterocolitis. AB - OBJECTIVE: To compare existing outcome prediction models and create a novel model to predict death or intestinal failure (IF) in infants with surgical necrotizing enterocolitis (NEC). STUDY DESIGN: A retrospective, observational cohort study conducted in a 2-campus health system in Atlanta, Georgia, from September 2009 to May 2015. Participants included all infants <=37 weeks of gestation with surgical NEC. Logistic regression was used to model the probability of death or IF, as a composite outcome, using preoperative variables defined by specifications from 3 existing prediction models: American College of Surgeons National Surgical Quality Improvement Program Pediatric, Score for Neonatal Acute Physiology Perinatal Extension, and Vermont Oxford Risk Adjustment Tool. A novel preoperative hybrid prediction model was also derived and validated against a patient cohort from a separate campus. RESULTS: Among 147 patients with surgical NEC, discrimination in predicting death or IF was greatest with American College of Surgeons National Surgical Quality Improvement Program Pediatric (area under the receiver operating characteristic curve [AUC], 0.84; 95% CI, 0.77-0.91) when compared with the Score for Neonatal Acute Physiology Perinatal Extension II (AUC, 0.60; 95% CI, 0.48-0.72) and Vermont Oxford Risk Adjustment Tool (AUC, 0.74; 95% CI, 0.65-0.83). A hybrid model was developed using 4 preoperative variables: the 1-minute Apgar score, inotrope use, mean blood pressure, and sepsis. The hybrid model AUC was 0.85 (95% CI, 0.78-0.92) in the derivation cohort and 0.77 (95% CI, 0.66-0.86) in the validation cohort. CONCLUSIONS: Preoperative prediction of death or IF among infants with surgical NEC is possible using existing prediction tools and, to a greater extent, using a newly proposed 4-variable hybrid model. PMID- 29173312 TI - Treatment of Children with Persistent and Chronic Idiopathic Thrombocytopenic Purpura: 4 Infusions of Rituximab and Three 4-Day Cycles of Dexamethasone. AB - OBJECTIVES: To assess initial and long-term outcome of children with persistent/chronic idiopathic thrombocytopenic purpura (ITP) treated with 4 infusions of rituximab and three 4-day cycles of dexamethasone (4R+3Dex) including cohorts with most benefit and/or treatment associated toxicity. STUDY DESIGN: All pediatric patients with ITP at Weill-Cornell who received 4R+3Dex were included in this retrospective study. Duration was median time from first rituximab infusion to treatment failure. Patient cohort included 33 children ages 1-18 years with persistent/chronic ITP; 19 were female, 10 of whom were adolescents. Every patient had failed more than 1 and usually several ITP treatments. RESULTS: Children were treated with rituximab, 375 mg/m2 weekly for 4 weeks and three 4-day courses of dexamethasone 28 mg/m2 (40 mg max). Average age of nonresponders was 7.75 years, and initial responders averaged 12.7 years (P = .0073); 30% maintained continuing response at 60 months or last check-up. Eight of the 10 patients who underwent remission were female with ITP <24 months prior to initiating 4R+3Dex. All responding male patients except 2 relapsed. CONCLUSIONS: Durable unmaintained ITP remission after 4R+3Dex was seen almost exclusively in female adolescents with <24 months duration of ITP. This provides a new therapeutic paradigm for a subpopulation with hard-to-treat chronic ITP. The pathophysiology of ITP underlying this distinction requires further elucidation.

AB - OBJECTIVE: To assess healthcare utilization patterns associated with high (>=3 visits/year) urgent care utilization. STUDY DESIGN: Retrospective analysis of 2 723 792 children who were less than 19 years of age in the 2013 Marketscan Medicaid database. Healthcare utilization categorized as inpatient, emergency department, urgent care, well-child primary care provider (PCP), acute PCP, and specialist visits was documented for 4 groups. We hypothesized that children with high urgent care utilization would have decreased utilization at other sites of care. Multivariable logistic models compared the odds of high urgent care utilization. RESULTS: Of children in the study population, 92.0% had no urgent care visits; 4.7% had 1; 1.5% had 2; and 1.0% had >=3. Patient attributes of high urgent care utilization were: ages 1-2 years (aOR = 2.32, 95% CI: 2.18-2.36, reference group: 13-18 years), presence of a complex chronic condition (CCC) (aOR = 1.98, 95% CI: 1.88-2.07, reference group: no CCC) and no CCC but >=3 chronic conditions (aOR = 2.85, 95% CI: 2.73-2.97, reference group: no CCC, no chronic conditions). High urgent care utilization was associated with >=5 PCP visits for acute care (aOR = 1.16, 95% CI: 1.11-1.20, reference group: 0 visits), and >=3 emergency department visits (aOR = 2.15, 95% CI: 2.10-2.23, reference group: 0 visits). CONCLUSIONS: Increased urgent care utilization was associated with an increase in overall healthcare utilization. Even though those with higher urgent care utilization had more visits for acute care, patients continued to see their PCP for both well-child and acute care visits.

PMID- 29173320 TI - Pulmonary Artery Pressures in School-Age Children Born Prematurely. AB - OBJECTIVES: To test the hypothesis that pulmonary artery pressures were higher in school aged children born extremely premature than those born at term. We also wanted to assess whether pulmonary artery pressures differed between children born prematurely with or without bronchopulmonary dysplasia (BPD) or between those randomized in the neonatal period to different ventilation modes. STUDY DESIGN: Transthoracic echocardiography was performed on 193 children born extremely premature (106 had BPD) and 110 children born at term when they were 11 14 years of age. Ninety-nine children born extremely premature had been supported by high-frequency oscillation and 94 by conventional ventilation. Tricuspid regurgitation was assessed in the apical 4-chamber and modified parasternal long axis views. Continuous-wave Doppler of the peak regurgitant jet velocity was used to estimate the right-ventricular-to-right-atrial systolic pressure gradient. RESULTS: Tricuspid regurgitation was measurable in 71% (137/193) of the children born preterm and 75% (83/110) of the children born at term (P .23). The children born prematurely compared with the children born at term had a greater peak tricuspid regurgitation velocity (2.21 vs 1.95 m/s, P < .001) and the children born prematurely who had BPD vs those without BPD had a greater peak tricuspid regurgitation velocity (P = .023). There were no significant differences in pulmonary artery pressures according to neonatal ventilation mode. CONCLUSIONS: Pulmonary artery pressures were estimated to be greater in 11- to 14-year-old children born extremely prematurely compared with those born at term and in those born prematurely who developed BPD compared with those who did not but did not differ significantly by neonatal ventilation mode.

PMID- 29173321 TI - Caffeine Citrate Dosing Adjustments to Assure Stable Caffeine Concentrations in Preterm Neonates. AB - OBJECTIVE: To identify dosing strategies that will assure stable caffeine concentrations in preterm neonates despite changing caffeine clearance during the first 8 weeks of life. METHODS: A 3-step simulation approach was used to compute caffeine doses that would achieve stable caffeine concentrations in the first 8 weeks after birth: (1) a mathematical weight change model was developed based on published weight distribution data; (2) a pharmacokinetic model was developed based on published models that accounts for individual body weight, postnatal, and gestational age on caffeine clearance and volume of distribution; and (3) caffeine concentrations were simulated for different dosing regimens. RESULTS: A standard dosing regimen of caffeine citrate (using a 20 mg/kg loading dose and 5 mg/kg/day maintenance dose) is associated with a maximal trough caffeine concentration of 15 mg/L after 1 week of treatment. However, trough concentrations subsequently exhibit a clinically relevant decrease because of increasing clearance. Model-based simulations indicate that an adjusted maintenance dose of 6 mg/kg/day in the second week, 7 mg/kg/day in the third to fourth week and 8 mg/kg/day in the fifth to eighth week assures stable caffeine concentrations with a target trough concentration of 15 mg/L. CONCLUSIONS: To assure stable caffeine concentrations during the first 8 weeks of life, the caffeine citrate maintenance dose needs to be increased by 1 mg/kg every 1-2 weeks. These simple adjustments are expected to maintain exposure to stable caffeine concentrations throughout this important developmental period and might enhance both the short- and long-term beneficial effects of caffeine treatment. PMID- 29173319 TI - Impact of the Neonatal Resuscitation Program-Recommended Low Oxygen Strategy on Outcomes of Infants Born Preterm. AB - OBJECTIVE: To evaluate the impact of the Neonatal Resuscitation Program (NRP) recommended low oxygen strategy (LOX) on neonatal morbidities, mortality, and neurodevelopmental outcomes in neonates born preterm. STUDY DESIGN: In March 2011, Parkland Hospital changed from a high oxygen strategy (HOX) of resuscitation with initial 100% oxygen and targeting 85%-94% oxygen saturation for delivery room resuscitation to a LOX with initial 21% oxygen and titrating oxygen to meet NRP-recommended transitional target saturations. Neonates <=28 weeks' gestational age born between August 2009 and April 2012 were identified. In this retrospective, observational study, neonates exposed to LOX vs HOX were compared for short-term morbidity, mortality, and long-term neurodevelopmental outcomes. Regression analysis was performed to control for confounding variables. RESULTS: Of 199 neonates, 110 were resuscitated with HOX and 89 with LOX. Compared with HOX, neonates exposed to LOX had lower oxygen exposure in the delivery room (5.2 +/- 1.5 vs 7.8 +/- 2.8 [?FiO2 * time min], P < .01), spent fewer days on oxygen (30 [5, 54] vs 46 [11, 82], P = .01), and had lower odds of developing bronchopulmonary dysplasia (aOR 0.4 [0.2, 0.9]). There was no difference in mortality (17 [20%] vs 20 [18%]), but neonates exposed to LOX had greater motor composite scores on Bayley Scales of Infant and Toddler Development Third edition assessment (91 [85, 97] vs 88 [76, 94], P < .01). CONCLUSION: The NRP-recommended LOX strategy was associated with improved respiratory morbidities and neurodevelopmental outcomes with no increase in mortality. Prospective trials to confirm the optimal oxygen strategy for the resuscitation of neonates born preterm are needed.

AB - OBJECTIVE: To assess the relationship between breastfeeding initiation time and postneonatal mortality, morbidity, and growth through 24 months in a cohort of Tanzanian infants. STUDY DESIGN: We included 4203 infants from 2 trials of micronutrient supplementation. We used Cox proportional hazards models or general estimating equations to estimate relative risks. RESULTS: A total of 13% of infants initiated breastfeeding >1 hour after birth (n = 536). There was no association between breastfeeding initiation time and risk of all-cause or cause specific mortality, nor infant growth failure, from 6 weeks to 2 years of age. However, delayed breastfeeding was associated with an increased risk of several common infectious morbidities in early infancy, including upper respiratory infection symptoms and vomiting. Compared with those who initiated breastfeeding within the first hour of birth, delayed breastfeeding initiation was associated with an 11% increased risk of cough (relative risk 1.11, 95% CI 1.02-1.21) and a 48% increased risk of difficulty breathing (relative risk 1.48, 95% CI 1.09-2.01) during the first 6 months. Delayed initiation was associated with a greater risk of difficulty breathing from 6 to 12 months of age, but it was not associated with risk of any other morbidity during this time, nor any morbidity between 12 and 24 months. CONCLUSION: Delayed breastfeeding initiation is associated with an increased risk of infant morbidity during the first 6 months of life. Early breastfeeding initiation, along with exclusive and prolonged breastfeeding, should be prioritized and promoted in efforts to improve child health. PMID- 29173325 TI - Intestinal Microbiota Composition in Sudden Infant Death Syndrome and Age-Matched Controls. AB - OBJECTIVE: To assess whether features of the infant intestinal microbiome, including the carriage of toxigenic bacteria, are associated with sudden infant death syndrome (SIDS). STUDY DESIGN: We undertook a case-controlled analysis of fecal microbiology in SIDS. Fecal material was obtained from 44 cases and 44 aged matched controls. Microbiota composition was determined by 16S ribosomal RNA gene amplicon sequencing and comparisons between cases and controls made based on both bacterial alpha diversity measures and unconstrained ordination. Specific quantitative polymerase chain reaction assays were used to determine intestinal carriage of Staphylococcus aureus, toxigenic Clostridium difficile, and pathogenic and nonpathogenic Escherichia coli. RESULTS: The microbial composition for the study population as a whole was consistent with previous studies of infants <12 months of age, with a correlation between alpha diversity and age (r2 = 0.08; P = .007). However, no difference was observed in alpha diversity between SIDS cases and controls (P > .4). Nonmetric multidimensional scaling also revealed no evidence of differences in microbiota dispersal between SIDS cases and controls (P = .4, permutational multivariate ANOVA test; Pseudo-F = 0.9), nor was a difference observed in microbiota dispersion (P = .19, PERMDISP test; F = 1.9). There were no significant intergroup differences in the carriage of S aureus, toxigenic C difficile, total E coli, or pathogenic E coli. CONCLUSIONS: We found no evidence of an association between altered intestinal microbiology and SIDS, or to support the development of strategies to reduce the incidence of SIDS that target intestinal microbiology. PMID- 29173326 TI - Capillary Blood Ketone Levels as an Indicator of Inadequate Breast Milk Intake in the Early Neonatal Period. AB - OBJECTIVE: To determine the utility of capillary blood ketone levels as an indicator of inadequate intake of breast milk in the early postnatal period. STUDY DESIGN: Levels of capillary blood beta-hydroxybutyrate (betaOHB), the main ketone body in the blood, were measured with a bedside ketone meter in 585 full term neonates aged 48-95 hours who were breastfed exclusively. Relationships between weight-loss percentage, blood sodium, glucose, pH, partial pressure of carbon dioxide, base-deficit levels, and betaOHB levels were investigated. The diagnostic accuracy of betaOHB for predicting excessive weight loss (weight loss >=10% of birth weight) and hypernatremic dehydration (blood sodium level >=150 mEq/L) was determined. RESULTS: betaOHB levels were correlated positively with weight-loss percentage and blood sodium levels and were correlated negatively with blood glucose levels. The diagnostic accuracy of betaOHB was 0.846 (optimal cut off, 1.55 mmol/L; sensitivity, 80.9%, specificity, 74.0%) for predicting excessive weight loss and 0.868 (optimal cut off, 1.85 mmol/L; sensitivity, 94.3%; specificity, 69.9%) for predicting hypernatremic dehydration according to the area under the receiver operating characteristic curve. Multiple logistic analysis revealed that betaOHB and weight loss percentage were the only independent predictors of hypernatremic dehydration. Increases in betaOHB levels also were associated with worsening metabolic acidosis and hypocapnia. CONCLUSION: High betaOHB levels were associated with inadequate intake of breast milk in the early postnatal period. The use of bedside capillary blood ketone levels may be clinically useful as an indicator of dehydration, energy depletion, and acid-base imbalance in breastfeeding infants in the early postnatal period. PMID- 29173327 TI - Cardiac Biomarker Release after Endurance Exercise in Male and Female Adults and Adolescents. AB - OBJECTIVES: To compare the responses of high-sensitivity cardiac troponin T (hs cTnT) and NH2-terminal probrain natriuretic peptide (NT-proBNP) after 60 minutes of swimming in male and female adults and adolescents with different pubertal status. STUDY DESIGN: Adolescent swimmers (25 male and 25 female) and adult swimmers (7 male and 9 female) participated in a 60-minute maximal swimming test with serial assessment of hs-cTnT and NT-proBNP at rest, immediately postexercise, and at 1, 3, 6, 12, and 24 hours postexercise. Adolescents were classified according to pubertal status: Tanner stages 3 (n = 14), 4 (n = 22), and 5 (n = 14). RESULTS: Exercise resulted in an increase in both biomarkers. hs cTnT responses to exercise were similar in adolescents with different pubertal status and adults, although there was substantial individual variability in peak hs-cTnT, with the upper reference limit exceeding in 62% of the participants. Postexercise kinetics for hs-cTnT were largely consistent across all groups with a return to near baseline levels 24 hours postexercise. The male participants showed higher values of hs-cTnT at baseline and postexercise. All groups had similar NT-proBNP responses to acute exercise and recovery. One swimmer exceeded the upper reference limit for NT-proBNP. CONCLUSIONS: An exercise-associated increase in hs-cTnT and NT-proBNP occurred in response to a 60-minute maximal swimming test that was independent of pubertal status/adolescent vs adults. The present data also suggests that baseline and postexercise hs-cTnT values are higher in male compared with female, with no sex differences in NT-proBNP values.

PMID- 29173331 TI - Dental disease before radiotherapy in patients with head and neck cancer: Clinical Registry of Dental Outcomes in Head and Neck Cancer Patients. AB - BACKGROUND: No evidence-based guidelines exist for preventive dental care before radiation therapy (RT) in patients with head and neck cancer (HNC). An ongoing multicenter, prospective cohort study, Clinical Registry of Dental Outcomes in Head and Neck Cancer Patients (OraRad), is addressing this knowledge gap. The authors evaluated the level of dental disease before RT in the OraRad cohort, factors associated with dental disease, and dental treatment recommendations made before RT. METHODS: As part of OraRad, the authors assessed caries, periodontal disease, dental recommendations, and dental interventions performed before RT. RESULTS: Baseline measures were reported for 356 participants (77% men) with mean (standard deviation) age of 59.9 (11.0) years. Measures included mean number of teeth (22.9), participants with at least 1 tooth with caries (37.2%), and participants with at least 1 tooth with probing depth 5 millimeters or greater (47.4%). Factors associated with less extensive dental disease before RT included having at least a high school diploma, having dental insurance, history of routine dental care, and a smaller tumor size (T1 or T2). Based on the dental examination before RT, 163 (49.5%) participants had dental treatment recommended before RT, with extractions recommended most frequently. CONCLUSION: Many patients with HCN require dental treatment before RT; more than one-third require extractions. PRACTICAL IMPLICATIONS: Most patients have some level of dental disease at the start of RT, indicating the importance of dental evaluation before RT. By observing dental outcomes after RT, OraRad has the potential to determine the best dental treatment recommendations for patients with HCN. PMID- 29173332 TI - Oral health status and longitudinal cardiometabolic risk in a national sample of young adults. AB - BACKGROUND: Dental and cardiometabolic diseases are highly prevalent, share many common risk factors, and begin during youth. Despite poor dental health being known to influence dietary behaviors that are in turn linked to cardiometabolic health, the role of oral health on concomitant and future cardiometabolic disease is understudied. We sought to determine the association of oral health with cardiometabolic markers during adolescence and early adulthood. METHODS: Our sample included 11,556 participants with data from waves 1 (when participants were aged 12 to 19 years) and 4 (when they were aged 26 to 32 years) of the National Longitudinal Study of Adolescent to Adult Health. Multivariable linear and logistic regression separately examined associations between different markers of oral health (that is, missing teeth, periodontal disease, and deferred dental care) and markers of cardiometabolic health (that is, lipids, blood pressure, and body mass index), adjusting for sociodemographic characteristics. RESULTS: Mean age was 29 years at follow-up (wave 4). In adjusted analyses, deferred dental care during both adolescence (beta = 1.25; 95% confidence interval [CI], 0.6 to 2.0; P = .001) and early adulthood (beta = 0.9; 95% CI, 0.4 to 1.3; P < .001) was associated with an increased body mass index during early adulthood. Deferred dental care in early adulthood was also associated with increased systolic (beta = 0.9; 95% CI, 0.4 to 1.5; P = .002) and diastolic (beta = 1.0; 95% CI, 0.5 to 1.5; P < .001) blood pressure values and an increased likelihood of being hypertensive (odds ratio = 1.2; 95% CI, 1.0 to 1.3; P = .03). CONCLUSIONS: In this nationally representative study deferred dental care during adolescence and concurrently in early adulthood was associated with poorer cardiometabolic disease during early adulthood. Providing better access to dental care may have benefits not only for oral health but also for long-term cardiometabolic health. PRACTICAL IMPLICATIONS: Deferred dental care during adolescence and early adulthood, but not recent tooth loss or periodontal disease, is associated with increased risk of cardiometabolic disease.

PMID- 29173343 TI - Multifaceted processes controlling the distribution of hazardous compounds in the spontaneous combustion of coal and the effect of these compounds on human health. AB - Pollution generated by hazardous elements and persistent organic compounds that affect coal fire is a major environmental concern because of its toxic nature, persistence, and potential risk to human health. The coal mining activities are growing in the state of Santa Catarina in Brazil, thus the collateral impacts on the health and economy are yet to be analyzed. In addition, the environment is also enduring the collateral damage as the waste materials directly influence the coal by-products applied in civil constructions. This study was aimed to establish the relationships between the composition, morphology, and structural characteristics of ultrafine particles emitted by coal mine fires. In Brazil, the self-combustions produced by Al-Ca-Fe-Mg-Si coal spheres are rich in chalcophile elements (As, Cd, Cu, Hg, Pb, Sb, Se, Sn, and Zn), lithophile elements (Ce, Hf, In, La, Th, and U), and siderophile elements (Co, Cr, Mo, Fe, Ni, and V). The relationship between nanomineralogy and the production of hazardous elements as analyzed by advanced methods for the geochemical analysis of different materials were also delineated. The information obtained by the mineral substance analysis may provide a better idea for the understanding of coal-fire development and assessing the response of particular coal in different combustion processes.

PMID- 29173347 TI - Dietary Energy Density in the Australian Adult Population from National Nutrition Surveys 1995 to 2012. AB - BACKGROUND: It is hypothesized that the observed proliferation of energy-dense, nutrient-poor foods globally is an important contributing factor to the development of the obesity epidemic. However, evidence that the population's dietary energy density has increased is sparse. The World Cancer Research Fund recommends that dietary energy density be <1.25 kcal/g to prevent weight gain. OBJECTIVE: The aim of this research was to determine whether the dietary energy density of the Australian population has changed between 1995 and 2012. DESIGN: A secondary analysis of two cross-sectional Australian national nutrition surveys from 1995 and 2011/2012 was conducted. PARTICIPANTS/SETTING: Participants of the surveys included adults aged 18 years and older (1995 n=10,986 and 2011/2012 n=9,435) completing 24-hour dietary recalls, including a second recall for a subset of the population (10.4% in 1995 and 64.6% in 2011/2012). MAIN OUTCOME MEASURES: Outcome measures included the change in dietary energy density (calculated as energy/weight of food [kcal/g] for food only) between surveys. STATISTICAL ANALYSIS: The National Cancer Institute method for "estimating ratios of two dietary components that are consumed nearly every day" was used to determine the usual distribution and the percentage of participants reporting energy density <1.25 kcal/g. RESULTS: The mean (standard deviation) dietary energy density was 1.59 (0.26) kcal/g and 1.64 (0.32) kcal/g (P<0.0001) in 1995 and 2011/2012, respectively, with 13% and 5% (P<0.0001) of the population meeting dietary energy-density recommendations. For those aged 70 years and older, the percentage with energy density <1.25 kcal/g decreased from 22% to 6% (P<0.0001) for men and from 33% to 11% (P<0.0001) for women in 1995 and 2011/2012, respectively. Among those aged 18 to 29 years, 1% of men in both surveys (P=0.8) and 4% of women in 1995 and 2% in 2011/2012 (P=0.01) reported energy density <1.25 kcal/g. CONCLUSIONS: Dietary energy density has increased between the two surveys and few people consumed low energy-dense diets in line with recommendations. The change was largely due to increased energy density of older adult's diets, while young adults had high dietary energy density at both time points. These data suggest efforts now focus on the evaluation of the role of modifying energy density of the diet to reduce the risk of weight gain in adults.

PMID- 29173348 TI - Use of Added Sugars Instead of Total Sugars May Improve the Capacity of the Health Star Rating System to Discriminate between Core and Discretionary Foods. AB - BACKGROUND: The Australian Government has introduced a voluntary front-of-package labeling system that includes total sugar in the calculation. OBJECTIVE: Our aim was to determine the effect of substituting added sugars for total sugars when calculating Health Star Ratings (HSR) and identify whether use of added sugars improves the capacity to distinguish between core and discretionary food products. DESIGN: This study included packaged food and beverage products available in Australian supermarkets (n=3,610). The product categories included in the analyses were breakfast cereals (n=513), fruit (n=571), milk (n=309), non alcoholic beverages (n=1,040), vegetables (n=787), and yogurt (n=390). Added sugar values were estimated for each product using a validated method. HSRs were then estimated for every product according to the established method using total sugar, and then by substituting added sugar for total sugar. The scoring system was not modified when added sugar was used in place of total sugar in the HSR calculation. Products were classified as core or discretionary based on the Australian Dietary Guidelines. To investigate whether use of added sugar in the HSR algorithm improved the distinction between core and discretionary products as defined by the Australian Dietary Guidelines, the proportion of core products that received an HSR of >=3.5 stars and the proportion of discretionary products that received an HSR of <3.5 stars, for algorithms based upon total vs added sugars were determined. RESULTS: There were 2,263 core and 1,347 discretionary foods; 1,684 of 3,610 (47%) products contained added sugar (median 8.4 g/100 g, interquartile range=5.0 to 12.2 g). When the HSR was calculated with added sugar instead of total sugar, an additional 166 (7.3%) core products received an HSR of >=3.5 stars and 103 (7.6%) discretionary products received a rating of >=3.5 stars. The odds of correctly identifying a product as core vs discretionary were increased by 61% (odds ratio 1.61, 95% CI 1.26 to 2.06; P<0.001) when the algorithm was based on added compared to total sugars. CONCLUSIONS: In the six product categories examined, substitution of added sugars for total sugars better aligned the HSR with the Australian Dietary Guidelines. Future work is required to investigate the impact in other product categories. PMID- 29173349 TI - Position of the Academy of Nutrition and Dietetics: Food Insecurity in the United States. AB - It is the position of the Academy of Nutrition and Dietetics that systematic and sustained action is needed to achieve food and nutrition security in the United States. To achieve food security, effective interventions are needed, along with adequate funding for, and increased utilization of, food and nutrition assistance programs; inclusion of nutrition education in such programs; strategies to support individual and household economic stability; and research to measure impact on food insecurity- and health-related outcomes. Millions of individuals living in the United States experience food insecurity. Negative nutritional and non-nutritional outcomes are associated with food insecurity across the lifespan, including substandard academic achievement, inadequate intake of key nutrients, increased risk for chronic disease, and poor psychological and cognitive functioning. Registered dietitian nutritionists and nutrition and dietetics technicians, registered, play key roles in addressing food insecurity and are uniquely positioned to make valuable contributions through competent and collaborative practice, provision of comprehensive food and nutrition education and training, innovative research related to all aspects of food insecurity, and advocacy efforts at the local, state, regional, and national levels.

PMID- 29173353 TI - Extracellular Microvesicles as Game Changers in Better Understanding the Complexity of Cellular Interactions-From Bench to Clinical Applications. AB - Recent research has led to wide acceptance and better understanding of a novel mechanism for cell-cell communication that employs a network of extracellular microvesicles (ExMVs). Derived from the plasma membrane or the endosomal membrane compartment, these small, spherical membrane fragments are secreted from the cell surface or in the process of exocytosis from endosomal membrane compartment and (1) with ligands expressed on their surface directly stimulate target cells in a paracrine manner, (2) transfer cell membrane receptors to target cells or (3) deliver encapsulated messenger RNA, microRNA, proteins and bioactive lipids to target cells. This represents an evolutionarily ancient mechanism by which cells signal their presence in the microenvironment, communicate with each other and affect the biology of neighboring cells. Evidence suggests the pivotal role of ExMVs in almost all biological processes within the body as well as their involvement in certain pathologies. Moreover, liquid biopsies based on deciphering the molecular signature of ExMVs promise to revolutionize laboratory diagnostics. At the same time, there are ongoing attempts to employ them as delivery vehicles for drugs as well as therapeutics in regenerative medicine, oncology and immunotherapy. PMID- 29173354 TI - Plasma Electrolyte Distributions in Humans-Normal or Skewed? AB - BACKGROUND: It is widely believed that plasma electrolyte levels are normally distributed. Statistical tests and calculations using plasma electrolyte data are often reported based on this assumption of normality. Examples include t tests, analysis of variance, correlations and confidence intervals. The purpose of our study was to determine whether plasma sodium (Na+), potassium (K+), chloride (Cl ) and bicarbonate [Formula: see text] distributions are indeed normally distributed. METHODS: We analyzed plasma electrolyte data from 237 consecutive adults (137 women and 100 men) who had normal results on a standard basic metabolic panel which included plasma electrolyte measurements. The skewness of each distribution (as a measure of its asymmetry) was compared to the zero skewness of a normal (Gaussian) distribution. RESULTS: The plasma Na+ distribution was skewed slightly to the right, but the skew was not significantly different from zero skew. The plasma Cl- distribution was skewed slightly to the left, but again the skew was not significantly different from zero skew. On the contrary, both the plasma K+ and [Formula: see text] distributions were significantly skewed to the right (P < 0.01 zero skew). There was also a suggestion from examining frequency distribution curves that K+ and [Formula: see text] distributions were bimodal. CONCLUSIONS: In adults with a normal basic metabolic panel, plasma potassium and bicarbonate levels are not normally distributed and may be bimodal. Thus, statistical methods to evaluate these 2 plasma electrolytes should be nonparametric tests and not parametric ones that require a normal distribution. PMID- 29173355 TI - Bedside Blood Glucose Monitoring in Critically Ill Patients: Comparison Between Arterial and Capillary Glucose. AB - BACKGROUND: Critically ill patients are at high risk of hypoglycemia and are particularly vulnerable to unrecognized hypoglycemia. Close blood glucose monitoring is therefore crucial. There are several options to conduct frequent blood glucose measurement and a number of conditions in intensive care unit patients may affect the accuracy of blood glucose measurement. The aim of the study was to compare the accuracy of capillary glucose by bedside glucometer with arterial samples by bedside glucometer and arterial samples by blood gas analyzer in critically ill patients through a prospective case-control study. MATERIALS AND METHODS: Arterial and capillary samples from 60 patients were taken simultaneously and were tested immediately at the bedside. Results of the paired measurements were compared and expressed as a correlation coefficient. RESULTS: Capillary glucose in the study group and control group were 9.73 +/- 2.28mmol/L and 8.9 +/- 1.86mmol/L, respectively; mean arterial glucose measured by glucometer in the study group and control group were 9.25 +/- 2.05mmol/L and 8.4 +/- 1.89mmol/L, respectively; and mean arterial glucose measured by blood gas analyzer in the study group and control group were 8.41 +/- 1.9mmol/L and 8.24 +/ 1.5mmol/L, respectively. Correlation between capillary values and arterial values measured by glucometer was less in the study group (r = 0.936, P < 0.001 and r = 0.973, P < 0.001). Correlation between capillary values measured by glucometer and arterial values measured by blood gas analyzer was also less in the study group (r = 0.897, P = 0.001 and r = 0.964, P < 0.001). CONCLUSIONS: Capillary blood glucose monitoring is reliable only in a selected group of critically ill patients. PMID- 29173356 TI - Contrast-Induced Nephropathy After Cardiac Catheterization: Culprits, Consequences and Predictors. AB - BACKGROUND: Contrast-induced nephropathy (CIN) is a common complication after radiocontrast exposure. METHODS: A retrospective medical record review of 513 hospitalized patients who underwent cardiac catheterization from June-December 2014 was done, of which 38 patients with end-stage renal disease and 57 patients without preprocedural creatinine were excluded. Serum creatinine concentration before the procedure and each day for 3 days after the procedure was recorded. CIN was defined as an increase in serum creatinine concentration by >=25% or >=0.5mg/dL from the preprocedural value within 72hours of contrast exposure. RESULTS: A total of 418 patients (mean age: 69.1 +/- 13.8 years, 55% males) were included in the study. Mean incidence of CIN was 3.7% (n = 16). CIN accounted for longer duration of hospitalization, lengthier intensive care unit admission, requirement of hemodialysis and higher mortality. Incidence of CIN was higher in the presence of preexisting atrial fibrillation (AF), congestive heart failure (CHF) and chronic kidney disease (CKD). When tested by univariate analysis, incidence of CIN was 13.8% in the AF group (P < 0.001), 8.6% in CHF group (P < 0.01) and 8.9% in CKD group (P < 0.002), compared with 2.3%, 1.9% and 2.4% in the absence of preexisting AF, CHF and CKD, respectively. On further testing using multivariate logistic regression model using AF, CHF and CKD as independent variables, development of CIN was strongly associated with preexisting AF with an odds ratio of 4.11, 95% CI: 1.40-12.07, P = 0.01. CONCLUSION: Identifying patients at risk is an important step in preventing CIN. Preexisting AF, independent of traditional risk factors, may increase the risk for CIN. PMID- 29173357 TI - Ischemia Modified Albumin Test to Detect Early Diabetic Complications. AB - BACKGROUND: The objective of this study was to assess the albumin cobalt binding (ACB) test in a cohort of type 2 diabetes patients. The ACB test is a simple, inexpensive, sensitive and robust test that could have important clinical application in detecting complications of type 2 diabetes mellitus. MATERIALS AND METHODS: We tested patients with type 2 diabetes without any clinically detectable complications or without any other comorbid conditions for serum ACB levels along with an equal number of age- and sex-matched healthy control subjects. ACB levels were compared after the patients with diabetes were investigated for various complications using standard statistical tests of significance. RESULTS: A total of 100 patients with type 2 diabetes were studied with age- and sex-matched healthy control subjects. Of the 100 patients, 78 had different complications on detailed laboratory testing. The patients with complications had significantly higher ACB test results when compared to the patients with diabetes without complications and to that of the control subjects (0.62 +/- 0.04, 0.42 +/- 0.07, 0.30 +/- 0.05absorbance units (ABSU)/mL, respectively. P < 0.001). All values in diabetics were significantly higher than that of controls. CONCLUSIONS: The serum ACB test is a sensitive indicator of complications developed in type 2 diabetes mellitus. Patients may be followed up with ACB results to detect early complications in this disease. PMID- 29173358 TI - Bacterial Etiology of Lower Respiratory Tract Infections and Their Antimicrobial Susceptibility. AB - BACKGROUND: Lower respiratory tract infection (LRTI) is one of the common major health problems in Nigeria causing morbidity and mortality. The study was conducted to determine the current trends of bacterial etiology of LRTIs among patients who attended the University of Nigeria Teaching Hospital (UNTH) and their antimicrobial susceptibility profile with special interest on pandrug resistance. MATERIALS AND METHODS: The study was conducted between February 2014 and June 2016 in the bacteriology laboratory of UNTH. Sputum samples of 954 patients with suspected LRTIs were received, after obtaining patients' informed consent and ethical clearance from the UNTH. The samples were collected and processed according to standard laboratory procedures. RESULTS: The mean age of the patients was 42.6 +/- 16.8 years. Of the total 954 sputum samples, 431 (45.2%) were positive for micro-organisms. A single, unique pathogen was recovered in 415 patients (96.3%), and 16 (3.7%) were polymicrobial. The most predominant single pathogen was Klebsiella pneumoniae, 215 (49.9%), and the most prevalent bacterial combination was Klebsiella spp and Pseudomonas aeruginosa, 6 (1.4%). Antimicrobial susceptibility testing shows that most isolates of K pneumoniae were susceptible to imipenem (94.8%). Among the bacteria, Escherichia coli (13.3%) ranked highest, followed by P aeruginosa (12.5%), and the least was Staphylococcus aureus (2.1%). CONCLUSIONS: Knowledge of the diversity of pathogens responsible for LRTIs and their susceptibility patterns to antibiotics, as well as antibiotic resistance surveillance, are important in the effective management of LRTI with prompt clinical and laboratory diagnosis along with appropriate treatment strategies. PMID- 29173359 TI - Effectiveness of Bulking Agent (Solesta) Therapy in Fecal Incontinence in Patients Refractory to Conventional Therapies. AB - BACKGROUND: Fecal incontinence is a problem that imposes considerable socioeconomic consequences. Despite many medical therapies, unmet needs remain. A new treatment option is a biocompatible bulking agent (Solesta) administered by submucosal injection in the distal rectum. The aims of this study are as follows: (1) To evaluate the efficacy and safety of this bulking agent in decreasing the severity of fecal incontinence (FI) and improving quality of life. (2) To obtain objective evidence of changes in anorectal physiology by high-resolution anorectal manometry pretreatment and posttreatment. MATERIALS AND METHODS: From January 2014 to June 2015, 17 patients who had failed medical therapy for FI received stabilized hyaluronate injected submucosally into the rectum under direct anoscopic visualization. The treatment was considered successful if patients achieved >50% reduction in FI events during monitoring for up to 12 months. RESULTS: After the first treatment session, 14 patients (82.3%) had a successful outcome. The remaining 3 patients received a second therapy 3 months later to achieve this result. At last follow-up, 7 of the 17 patients (41%) were having no FI events. The remaining patients had reduction in fecal accidents from a mean of 6.4/week baseline to 2.8/week during follow-up. CONCLUSIONS: Intrarectal injection of stabilized hyaluronate is effective for treating FI in patients who had failed standard medical treatments and is technically easy and safely performed as an outpatient procedure. PMID- 29173360 TI - Combined Assessment of Relaxin and B-Type Natriuretic Peptide Improves Diagnostic Value in Patients With Congestive Heart Failure. AB - BACKGROUND: To improve the poor prognosis of congestive heart failure (CHF), early and accurate diagnosis is necessary. Relaxin is an endogenous cardiovascular peptide, and its plasma level is usually increased in patients with CHF. In this pilot study, we aimed to determine the diagnostic value of relaxin and B-type natriuretic peptide (BNP) in patients with and without CHF. MATERIALS AND METHODS: The plasma level of relaxin was measured by enzyme-linked immunosorbent assay and plasma level of BNP by fluorescence immunoassay. The area under the receiver operating characteristic curve was used to assess the diagnostic value of relaxin and BNP. RESULTS: We included 81 patients with decompenstated CHF and 36 controls. Plasma levels of relaxin and BNP were both higher in CHF patients than in controls. The correlation between plasma levels of relaxin and BNP and between relaxin or BNP and cardiac function was nonlinear. Relaxin had medium diagnostic value, and BNP had higher value for cardiac function and CHF. At a cutoff of 39.76pg/mL relaxin, sensitivity was 82.7%, specificity 55.6%, sum of the highest positive predictive value 80.5% and negative predictive value 58.8%. Although the diagnostic value was not better for relaxin than BNP, their combined assessment improved the sensitivity and specificity of diagnosis for CHF as compared with BNP alone. CONCLUSIONS: Combined assessment of relaxin and BNP may improve the diagnosis of decompensated CHF, which may have potential application in the clinic. PMID- 29173361 TI - Eosinophilic Myocarditis. AB - Persistent eosinophilia can cause cardiac tissue damage, typically in the form of eosinophilic myocarditis, whether the underlying cause is reactive, a clonal myeloid disorder, or idiopathic hypereosinophilic syndrome (HES). Eosinophilic myocarditis ranges from mild localized disease to multifocal widespread infiltrates associated with myocardial necrosis, thrombotic complications and endomyocardial fibrosis. Systemic treatment varies widely depending on the underlying cause, so thorough investigation and precise diagnosis are essential. Evaluation includes assessment for reactive causes of eosinophilia (vasculitis such as eosinophilic granulomatosis and polyangiitis or Churg-Strauss, parasitic infection, autoimmune disease, immunoglobulinG4-related disease, medications and other causes), genetic lesions characteristic of clonal myeloid disorders (platelet-derived growth factor receptor-alpha, platelet-derived growth factor receptor-beta and fibroblast growth factor receptor 1) and flow cytometry and molecular studies for the aberrant T cells characteristic of lymphocyte-variant HES . Patients with reactive eosinophilia require treatment for the underlying cause, such as antiparasitic therapy for helminthic infection or immunosuppression for eosinophilic granulomatosis and polyangiitis or Churg Strauss. Those with a myeloid clone often benefit from the tyrosine kinase inhibitor imatinib. Steroids are the first-line treatment for idiopathic HES and lymphocyte-variant HES, and hydroxyurea or (pegylated) interferon-alpha may be used for relapsed or refractory disease. Mepolizumab, an anti-interleukin-5 monoclonal antibody, is an effective steroid-sparing agent in HES but is not widely available for this indication. PMID- 29173362 TI - Propofol Potentiates Sevoflurane-Induced Inhibition of Nuclear Factor--kappaB Mediated Inflammatory Responses and Regulation of Mitogen-Activated Protein Kinases Pathways via Toll-like Receptor 4 Signaling in Lipopolysaccharide-Induced Acute Lung Injury in Mice. AB - BACKGROUND: Toll-like receptor 4 (TLR4)-induced initiation of mitogen-activated protein kinases and the nuclear factor-kappa B signaling cascade is reportedly involved in inflammatory responses during lung injury. Studies have found that volatile anesthetics, such as isoflurane and sevoflurane, inhibit inflammation. This investigation explored the protective effects of propofol and whether propofol potentiates the protective effects of sevoflurane against lipopolysaccharide (LPS)-induced acute lung injury. MATERIALS AND METHODS: Male BALB/c mice were treated with LPS (10MUg/mouse; intranasal instillation) to induce acute lung injury. Mice were exposed to sevoflurane (3%; 6 hours) alone or combined with propofol (10 or 20mg/kg body weight; subcutaneously) followed by sevoflurane for 1 hour before the LPS challenge. RESULTS: Sevoflurane with or without propofol attenuated pulmonary edema, restored altered lung architecture and reduced influx of inflammatory cells into bronchoalveolar lavage fluid after the LPS challenge. LPS-mediated overproduction of the proinflammatory cytokines tumor necrosis factor-alpha, interleukin-1beta, and interleukin-6 as well as nitric oxide, were reduced. Sevoflurane either alone or with propofol downregulated TLR4 and TLR4-mediated mitogen-activated protein kinase and nuclear factor-kappa B signaling. CONCLUSIONS: Combined exposure to propofol and sevoflurane was more effective than sevoflurane administered alone, suggesting the positive effects of propofol on sevoflurane-mediated anti-inflammatory effects. PMID- 29173363 TI - Novel Survivin-Targeted Small Interfering RNA Delivered by Nanoparticles. AB - BACKGROUND: The aim of the present study was to investigate the antitumor effect of our novel survivin-targeted small interfering RNA (siRNA) nanoliposomes on xenograft mouse models with human cervical carcinoma HeLa cells, and to evaluate pharmacokinetics. MATERIALS AND METHODS: siRNA nanoliposome was prepared and transfected into xenograft mouse models. Tumor growth in mice was determined and survivin expression was analyzed by using histologic and immunohischemical staining. Furthermore, low, moderate and high doses of survivin siRNA nanoliposomes were injected in 3 groups, and plasma concentrations were detected at various time points by reverse transcription quantitative polymerase chain reaction. Biodistribution of siRNA in tumor and other important organs were also determined. RESULTS: Survivin expression was significantly downregulated by survivin siRNA delivery mediated by nanoliposome, along with significant suppression of cell growth. Peak concentrations were obtained at 15 minutes after injection in each group, with 1,042,538.00, 6,837,099.54 and 14,631,333.15pg/mL, respectively, and the plasma concentration decreased significantly after 24 hours. The half-time life of survivin siRNA nanoliposomes in each group was 3.60, 2.64 and 2.80 hours, respectively. The area under curve values were 952,190.88, 6,800,687.79 and 13,803,680.96h/pg/mL, and the total drug clearance were 1,050.12, 441.13 and 434.67mL/h/kg. A significant accumulation of Cy5-labeled siRNA was found in the tumor, and a nonspecific accumulation was reduced significantly in lung. CONCLUSIONS: Our findings revealed that survivin suppression by siRNA may contribute to tumor inhibition through both proliferation inhibition and apoptosis promotion effect, and the pharmacokinetic characteristics serve as a fundamental role for further studies on its applicability for cancer therapy. PMID- 29173364 TI - Painless Aortic Dissection. AB - Painless aortic dissection (PAoD) has been previously linked to poor outcomes. We recently encountered a case of a patient with PAoD presenting with dyspnea; the clue to diagnosis was the presence of a loud aortic diastolic murmur. A systematic review of the literature revealed 86 other cases, 62% of which occurred in men with a mean age of 65 years. Left-sided neurologic deficits were the most common presentation, followed by dyspnea and bilateral lower extremity deficits. Pulse asymmetry was found in 53% of patients, as 29% had right-left asymmetry and 24% had upper-lower asymmetry. Cumulatively, 88% of the cases were type A dissection and 51% of the patients died. Erroneous application of fibrinolysis and anticoagulation occurred in multiple instances. PAoD is rare but potentially fatal; a high index of suspicion and a thorough cardiovascular examination are needed to establish the diagnosis before applying possible harmful interventions such as fibrinolysis, vasodilation or anticoagulation.

AB - AORN conducted its 15th annual compensation survey for perioperative nurses in June 2017. A multiple regression model was used to examine how several variables, including job title, educational level, certification, experience, and geographic region, affect nurse compensation. Comparisons between the 2017 data and data from previous years are presented. The effects of other forms of compensation (eg, on-call compensation, overtime, bonuses, shift differentials, benefits) on base compensation rates are examined. Additional analyses explore the current state of the nursing shortage and the sources of job satisfaction and dissatisfaction. PMID- 29173374 TI - Minimizing Sources of Airborne, Aerosolized, and Contact Contaminants in the OR Environment. AB - Surgical site infections are unintended consequences of surgery that can cause harm to patients and place financial burdens on health care organizations. Extrinsic factors in the OR-including health care providers' behavior and practices that modify air movement, the physical environment, equipment, or surgical instruments-can increase microbial contamination. Microbes can be transported into the surgical incision by airborne or contact routes and contribute to a surgical site infection. Simple practices to prevent infection such as minimizing airborne particles and contaminants, maintaining equipment according to the manufacturer's recommendations, cleaning and disinfecting the environment and surgical instruments, and performing proper hand hygiene-can reduce the degree of microbial contamination. Perioperative leaders and health care providers can help decrease the patient's risk of surgical site infection with proactive preventive practices that break the chain of infection. PMID- 29173375 TI - Operation Clean Air: Implementing a Surgical Smoke Evacuation Program. AB - Surgical smoke is a hazardous byproduct of any surgery involving a laser or an electrosurgical unit. Although research and professional organizations identified surgical smoke as harmful many years ago, this byproduct continues to be a safety hazard in the OR. An interdisciplinary team at a large academic medical center sought to address the exposure of patients and perioperative team members to surgical smoke. The team used the nursing process to resolve the lack of smoke evacuator equipment and surgical smoke staff member knowledge. To increase awareness of the hazards of surgical smoke, we gave presentations to nursing staff members and surgeons, who then completed educational modules. We conducted audits in all ORs to monitor compliance. The use of smoke evacuation supplies has more than quadrupled since education began. Additional unit-based education continues every day and is a constant reminder that safety is the responsibility of all perioperative team members. PMID- 29173376 TI - Evaluation of a Brief Team Training Intervention in Surgery: A Mixed-Methods Study. AB - The aim of this study was to evaluate a brief team training program in relation to teams' observed nontechnical skills (NTSs) in surgery, teams' perceptions of safety culture, and the training implementation. We used mixed methods to analyze structured observations of 179 surgeries, semistructured interviews with surgical team members from four selected surgical specialties, and a survey. There were significant (P < .001) improvements in surgical teams' observed NTSs and in the use of the World Health Organization's Surgical Safety Checklist after participation in the training program. Nonsignificant results included increased perceived safety climate and decreased perceived teamwork climate. From participant interviews, we identified that production pressure and time constraints were the biggest barriers to implementation and the greatest enabler was the organization's support for staff education initiatives. Most participants perceived the content of the program to be useful. These results highlight the complexities inherent in the development and evaluation of interdisciplinary patient safety interventions. PMID- 29173377 TI - Navigating Nursing Education. AB - All nurses must embrace lifelong learning and engage in academic progression to help transform health care. This article explores the various forms of nursing education and focuses on the types of degrees available, different practice roles and pathways, types of educational institutions and programs, and accreditation and its governing bodies. The benefits to nurses who pursue additional education include career mobility, additional responsibilities, and personal satisfaction. The benefits to patients include receiving the most current evidence-based care from a more highly educated and competent workforce. PMID- 29173378 TI - Health Care Workers' Use and Cleaning of X-Ray Aprons and Thyroid Shields. AB - We evaluated the use and cleaning of x-ray aprons and thyroid shields by surveying rural hospital system health care workers who wear x-ray aprons and thyroid shields. One hundred fifty-five of the 173 respondents were RNs (89.6%), and 94 respondents were from inpatient or outpatient surgical settings (54.3%). One hundred thirty-five respondents (78.0%) reported soiled x-ray aprons or thyroid shields, and 52 (30.1%) reported shield odors. Eighty-three participants (48.0%) indicated they never spot cleaned. Standard department cleaning never occurred for 37 x-ray aprons or thyroid shields (21.4%); and 114 x-ray aprons or thyroid shields (65.9%) contacted a patient or patient item 1 to 10 times per shift. Twenty-six participants (15%) specified there were policies and procedures for cleaning x-ray aprons and thyroid shields. Use of evidence-based cleaning guidelines and manufacturer's requirements for effective spot and standard cleaning of the protective aprons and thyroid shields are warranted.

PMID- 29173395 TI - Challenges, diligence, and a breakthrough in donation after circulatory death in heart transplantation. PMID- 29173394 TI - Outcome after heart transplantation from donation after circulatory-determined death donors. AB - BACKGROUND: The requirement for heart transplantation is increasing, vastly outgrowing the supply of hearts available from donation after brain death (DBD) donors. Transplanting hearts after donation after circulatory-determined death (DCD) may be a viable additive alternative to DBD donors. This study compared outcomes from the largest single-center experience of DCD heart transplantation against matched DBD heart transplants. METHODS: DCD hearts were retrieved using normothermic regional perfusion (NRP) or direct procurement and perfusion (DPP). During NRP, perfusion was restored to the arrested heart within the donor with the exclusion of the cerebral circulation, whereas DPP hearts were removed directly. All hearts were maintained on machine perfusion during transportation. A retrospective cohort of DBD heart transplants, matched for donor and recipient characteristics, was used as a comparison group. The primary outcome measure of this study (set by the United Kingdom regulatory body) was 90-day survival. RESULTS: There were 28 DCD heart transplants performed during the 25-month study period. Survival at 90 days was not significantly different between DCD and matched DBD transplant recipients (DCD, 92%; DBD, 96%; p = 1.0). Hospital length of stay, treated rejection episodes, allograft function, and 1-year survival (DCD, 86%; DBD, 88%; p = 0.98) were comparable between groups. The method of retrieval (NRP or DPP) was not associated with a difference in outcome. CONCLUSIONS: These results suggest that heart transplantation from DCD heart donation provides comparable short-term outcomes to traditional DBD heart transplants and can serve to increase heart transplant activity in well-selected patients.

PMID- 29173398 TI - Sudden Cardiac Death: Interface Between Pathophysiology and Epidemiology. AB - The population incidence of sudden cardiac arrest (SCA) and sudden cardiac death have not changed appreciably during the decades of improvement in general outcomes from cardiovascular diseases, but the age, clinical circumstances, and pathophysiologic mechanisms have. The epidemiology and pathophysiology of SCA are linked, in that mechanisms of SCA can be modeled based on substrate and expression characteristics. The goal for the future is to expand pathophysiologic and epidemiologic interactions to achieve strong individual risk prediction, to complement the limits of application of population risk data to individuals. PMID- 29173399 TI - Basic Electrophysiologic Mechanisms of Sudden Cardiac Death Caused by Acute Myocardial Ischemia and Infarction. AB - Sudden cardiac death caused by acute ischemia results from electrophysiologic changes in myocardium deprived of its blood supply. These changes include a reduction in resting potential and phase 0 depolarization and an increase in intercellular resistivity that slow conduction, cause conduction block, and lead to reentrant excitation and ventricular fibrillation. Reperfusion of a coronary artery after a short period of occlusion leads to similar changes. PMID- 29173400 TI - Channelopathies as Causes of Sudden Cardiac Death. AB - This article reviews the main clinical aspects of 3 channelopathies: the long QT syndrome, the catecholaminergic polymorphic ventricular tachycardia, and the Brugada syndrome. The text summarizes our views on clinical presentation and diagnosis, on risk stratification, and on therapy. Special attention is given to the progress in the understanding of the genetic bases and on the growing impact of genetics on therapy, which, at least in the case of long QT syndrome, now allows gene-specific management. PMID- 29173401 TI - Public Access Defibrillation: Is This Making Any Difference? Controversial Issues in Resuscitation from Cardiac Arrest. AB - Public access defibrillation is particularly valuable in witnessed cardiac arrests that occur in public places. Bystander and police use of automated external defibrillators (AEDs) has increased over the past 15 years, resulting in improved survival with normal or near-normal neurologic function. There is great promise for increasing bystander use of defibrillators as the technology is applied to linking patients with shockable arrests to volunteers committed to bringing AEDs to the patients. There continues to be controversy as to the value of epinephrine, antiarrhythmic drugs, hypothermia, and mechanical chest compression in resuscitative efforts. PMID- 29173402 TI - Sudden Cardiac Death During Sports Activities in the General Population. AB - Regular exercise reduces cardiovascular and overall mortality. Participation in sports is an important determinant of cardiovascular health and fitness. Regular sports activity is associated with a smaller risk of sudden cardiac death (SCD). However, there is a small risk of sports-related SCD. Sports-related SCD accounts for approximately 5% of total SCD. SCD among athletes comprises only a fraction of all sports-related SCD. Sport-related SCD has a male predominance and an average age of affliction of 45 to 50 years. Survival is better than for other SCD. This review summarizes links between sports and SCD and discusses current knowledge and controversies. PMID- 29173403 TI - Sudden Cardiac Death in Children and Adolescents. AB - Sudden cardiac death (SCD) is a rare but devastating event in children and adolescents. Etiologies include congenital heart disease, cardiomyopathies, primary arrhythmia syndromes, and miscellaneous conditions. Challenges in the diagnosis and prevention of SCD in the young are reviewed. PMID- 29173404 TI - Sudden Cardiac Death in Genetic Cardiomyopathies. AB - Sudden cardiac death (SCD) caused by ventricular arrhythmias is common in patients with genetic cardiomyopathies (CMs) including dilated CM, hypertrophic CM, and arrhythmogenic right ventricular CM (ARVC). Phenotypic features can identify individuals at high enough risk to warrant placement of an implantable cardioverter-defibrillator, although risk stratification schemes remain imperfect. Genetic testing is valuable for family cascade screening but with few exceptions (eg, LMNA mutations) do not identify higher risk for SCD. Although randomized trials are lacking, observational data suggest that ICDs can be beneficial. Vigorous exercise can exacerbate ARVC disease progression and increase likelihood of ventricular arrhythmias. PMID- 29173405 TI - Electrocardiographic Markers of Sudden Cardiac Death (Including Left Ventricular Hypertrophy). AB - Although the electrocardiograph (ECG) was invented more than 100 years ago, it remains the most commonly used test in clinical medicine. It is easy to perform, relatively cheap, and results are readily available. Interpretation, however, needs expertise and knowledge. New data, phenomenon, and syndromes are continually discovered by the ECG. It is important to differentiate between normal and abnormal ECGs first and then try to correlate the findings with clinical pathologies. Furthermore, the ECG is an integral part of the screening model for a variety of conditions such as channelopathies, athletes, preoperative risk profile, and remains the cardiologist's best friend. PMID- 29173406 TI - Prediction and Prevention of Sudden Cardiac Death. AB - Sudden death is a major problem, with significant impact on public health. Many conditions predispose to sudden cardiac death and sudden cardiac arrest (SCA), foremost among them coronary artery disease, and an effective therapy exists in the form of the implantable cardioverter defibrillator. Risk stratification for SCA remains imperfect, especially for patients with nonischemic cardiomyopathy. Ongoing trials may make it easier to identify those at high risk, and potentially those at very low risk, in the future. PMID- 29173407 TI - Role of Cardiac Imaging in Evaluating Risk for Sudden Cardiac Death. AB - Sudden cardiac death (SCD) is a major cause of death from cardiovascular disease. Our ability to predict patients at the highest risk of developing lethal ventricular arrhythmias remains limited. Despite recent studies evaluating risk stratification tools, there is no optimal strategy. Cardiac imaging provides the opportunity to assess left ventricular ejection fraction, strain, fibrosis, and sympathetic innervation, all of which are pathophysiologically related to SCD risk. These modalities may play a role in the identification of vulnerable anatomic substrates that provide the pathophysiologic basis for SCD. Further studies are required to identify optimal imaging platform for risk assessment. PMID- 29173408 TI - Biomarkers to Predict Cardiovascular Death. AB - This article reviews biomarkers that have been shown to identify subjects at increased risk for cardiovascular death within the general population, in those with established coronary artery disease, and in those with heart failure. Use of biomarkers for risk stratification for sudden cardiac death continues to evolve. It seems that a multimarker strategy for risk stratification using simple measures of circulating proteins and usual clinical risk factors, particularly in patients with known coronary artery disease, can be used to identify patients at near-term risk of death. Whether similar strategies in the general population will prove to be cost-effective needs to be investigated. PMID- 29173410 TI - Sudden Cardiac Death in Ischemic Heart Disease: Pathophysiology and Risk Stratification. AB - Sudden cardiac death (SCD) accounts for approximately 360,000 deaths annually in the United States. Ischemic heart disease is the major cause of death in the general adult population. SCD can be due to arrhythmic or nonarrhythmic cardiac causes. Arrhythmic SCD may be caused by ventricular tachyarrhythmia or pulseless electrical activity/asystole. This article reviews the most recent pathophysiology and risk stratification strategies for SCD, emphasizing electrophysiologic surrogates of conduction disorder, dispersion of repolarization, and autonomic imbalance. Factors that modify arrhythmic death are addressed. PMID- 29173411 TI - Ventricular Arrhythmias and Sudden Cardiac Death. AB - Ventricular arrhythmias remain a significant cause of sudden cardiac death (SCD), and knowledge of their cause and high-risk features is important. SCD occurs when the interaction between vulnerable substrates and acute triggers results in sustained ventricular tachycardia progressing to ventricular fibrillation. Here, the authors aim to review the role of ventricular arrhythmias in SCD, first by approaching the substrates that support ventricular arrhythmias, and then by exploring features of these substrates and the acute triggers that may lead to SCD. PMID- 29173412 TI - Heart Failure and Sudden Cardiac Death. AB - The Centers for Diseases Control and Prevention estimates that 5.7 million adults in the United States suffer from heart failure and 1 in 9 deaths in 2009 cited heart failure as a contributing cause. Almost 50% of patients who are diagnosed with heart failure die within 5 years of diagnosis. Cardiovascular disease is a public health burden. The prognosis of patients with heart failure has improved significantly. However, the risk for death remains high. Managing sudden death risk and intervening appropriately with primary or secondary prevention strategies are of paramount importance. PMID- 29173409 TI - Cardiac Innervation and the Autonomic Nervous System in Sudden Cardiac Death. AB - Neural remodeling in the autonomic nervous system contributes to sudden cardiac death. The fabric of cardiac excitability and propagation is controlled by autonomic innervation. Heart disease predisposes to malignant ventricular arrhythmias by causing neural remodeling at the level of the myocardium, the intrinsic cardiac ganglia, extracardiac intrathoracic sympathetic ganglia, extrathoracic ganglia, spinal cord, and the brainstem, as well as the higher centers and the cortex. Therapeutic strategies at each of these levels aim to restore the balance between the sympathetic and parasympathetic branches. Understanding this complex neural network will provide important therapeutic insights into the treatment of sudden cardiac death. PMID- 29173413 TI - Sudden Cardiac Death in Acute Coronary Syndromes. AB - Sudden cardiac death in acute coronary syndromes mostly results from complex ventricular arrhythmias. Although the incidence has fallen with contemporary management, they still pose a threat for many patients. Treatment consists of immediate termination by electrical cardioversion and prompt coronary revascularization for relief of ischemia. Beta-blockers administered prophylactically have a protective effect. For recurrent episodes, pharmacologic treatment consists of beta-blockers and amiodarone, or, in nonresponsive patients, lidocaine. Other antiarrhythmic drugs play only a marginal role. Catheter ablation performed in qualified centers can be effective in recurrent episodes of ventricular tachycardia or ventricular fibrillation triggered by premature ventricular contractions. PMID- 29173414 TI - Neuromuscular Disease: Cardiac Manifestations and Sudden Death Risk. AB - Cardiovascular complications of neuromuscular diseases disproportionately affect the cardiac conduction system. Cardiomyopathy and cardiac arrhythmias produce significant morbidity and mortality. Patients with neuromuscular diseases should be carefully and frequently evaluated for the presence of bradycardia, heart block, and tachyarrhythmias. Preemptive treatment with permanent pacemakers or implanted defibrillators is appropriate in patients with conduction system disease or who are at risk for ventricular arrhythmias. PMID- 29173415 TI - Sudden Cardiac Death: Lessons Learned from Cardiac Implantable Rhythm Devices. AB - Trials have demonstrated that implantable-cardioverter defibrillators (ICDs) are effective in preventing sudden cardiac death (SCD). The degree of left ventricular dysfunction is the only parameter to identify primary prevention populations at higher risk of SCD in which ICDs may reduce longitudinal mortality risk. Clinical application of current stratification approaches based on left ventricular ejection fraction (LVEF) alone has failed to prevent most SCD in the general population. This lack of specificity has resulted in a significant number of potentially unnecessary ICDs. Future studies should focus on newer risk markers to improve the predictive value of LVEF and SCD prevention. PMID- 29173416 TI - Primary Prevention Implantable Cardiac Defibrillator Trials: What Have We Learned? AB - Patients with impaired left ventricular systolic function frequently die suddenly because of arrhythmic and nonarrhythmic causes. Nine trials have evaluated the utility of implantable cardioverter-defibrillator (ICDs) primary prevention of sudden cardiac death. Individuals with stable ischemic heart disease (no recent myocardial infarction), especially those with inducible arrhythmias, seem to derive the highest mortality benefit from prophylactic ICD use. The role of ICDs in other patient populations is much less clear and may even be harmful. The use of antiarrhythmic medications has not been shown to improve survival in any patient population at risk for sudden death. PMID- 29173417 TI - The Subcutaneous Defibrillator. AB - The transvenous implantable cardioverter-defibrillator (ICD) has been shown in multiple studies to be effective in the prevention of sudden cardiac death in select populations. The Achilles heel of traditional ICD technology has been the transvenous lead. The subcutaneous ICD provides effective sudden death protection while avoiding lead-related complications of traditional transvenous systems. The subcutaneous ICD is a reasonable option for patients with an ICD indication who do not need bradycardia pacing or cardiac resynchronization therapy. PMID- 29173418 TI - Future Directions: Management of Sudden Cardiac Death. AB - There will always be a need to optimize early recognition and treatment of sudden cardiac arrest. For out-of-hospital cardiac arrest, this requires a complex system of care involving bystanders, 911 dispatchers, and emergency medical service and hospital-based providers. Optimizing this system is fundamental to improving outcomes. In addition, personnel and resources are needed to develop and sustain a research pipeline that will bring new scientific discoveries and technologies to the field. The 2015 Institute of Medicine report, "Strategies to Improve Cardiac Arrest Survival: A Time to Act," provides a roadmap. PMID- 29173419 TI - Sudden Cardiac Death: Back to the Future.

AB - Degenerative cervical spondylosis (DCM) is an umbrella term used to describe myelopathy caused by various degenerative changes in the cervical spine. This article outlines the spectrum of DCM and reviews the epidemiology of each factor composing DCM. The uniform term of DCM is expected to elucidate the epidemiology of myelopathy caused by degenerative changes of the cervical spine." PMID- 29173422 TI - History and Evolution of Laminoplasty. AB - Techniques of expansive laminoplasty for degenerative cervical myelopathy and ossified posterior longitudinal ligament are described, focusing on the history of the surgical procedure. Laminectomy was the only approach for posterior decompression before Japanese orthopedic surgeons introduced laminoplasty from the 1970s to the 1980s to overcome the poor outcomes of laminectomy. Recent laminoplasty techniques offer less invasive maneuvers to the posterior cervical muscle structures to reduce axial neck pain and to obtain better functional outcome, but every operation is carried out based on the unchanged initial concept. Some recent attempts to improve the surgical results are also discussed. PMID- 29173423 TI - Significant Predictors of Outcome Following Surgery for the Treatment of Degenerative Cervical Myelopathy: A Systematic Review of the Literature. AB - This systematic review aims to summarize important clinical predictors of outcomes in patients undergoing surgery for the treatment of degenerative cervical myelopathy. Based on the results of this article, patients with a longer duration of symptoms and more severe myelopathy are likely to have worse surgical outcomes. With respect to age, several studies have indicated that elderly patients are less likely to translate neurologic recovery into functional improvements. However, many other studies have failed to identify a significant association between age and outcomes. Finally, smoking status and presence of comorbidities may be important predictors of outcomes. PMID- 29173424 TI - Neurologic Complications in Managing Degenerative Cervical Myelopathy: Pathogenesis, Prevention, and Management. AB - Degenerative cervical myelopathy is a common neurologic condition induced by compression of the spinal cord due to degenerative changes of the cervical spine. It is one of the leading causes of acquired disability in adults and manifests as a slow deterioration of the symptoms in a majority of the patients. A variety of nonsurgical and surgical treatments have been performed to ameliorate or halt the symptoms, and a number of articles describe their methods, efficacy, and complications. In this article, the pathogenesis, prevention, and management of the neurologic complications are reviewed. PMID- 29173425 TI - Pathobiology of Degenerative Cervical Myelopathy. AB - Degenerative cervical myelopathy (DCM) is a common spinal cord disease caused by chronic mechanical compression of the spinal cord. The mechanism by which mechanical stress results in spinal cord injury is poorly understood. The most common mechanisms involved in the pathobiology of DCM include apoptosis, inflammation, and vascular changes leading to loss of neurons, axonal degeneration, and myelin changes. However, the exact pathophysiologic mechanisms of DCM are unclear. A better understanding of the pathogenesis of DCM is required for the development of treatments to improve outcomes. This review highlights the mechanisms of injury and pathology in DCM. PMID- 29173426 TI - Options of Management of the Patient with Mild Degenerative Cervical Myelopathy. AB - Surgical management of patients with mild degenerative cervical myelopathy (DCM) is controversial. This article reviews 84 subjects with cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL) who underwent surgical treatment. Nine had mild myelopathy: 6 CSM and 3 OPLL. Seven presented with pain or numbness of upper extremities. MRI revealed intramedullary hyperintensity in 55.6%. Five underwent anterior decompression and fusion, whereas 4 were operated posteriorly. Pain and intramedullary signal change on MRI are important. Management of patients with mild DCM should be determined individually, considering benefits and risks in long-term conservative treatment and surgery. PMID- 29173427 TI - Management of the Patient with Cervical Cord Compression but no Evidence of Myelopathy: What Should We do? AB - Degenerative cervical myelopathy (DCM) eventually affects not only activities of daily living but also quality of life. DCM is usually a gradually progressive, sometimes irreversible, disease of the cervical spinal cord, although there is always a risk of acute deterioration caused by minor trauma. There is still not enough evidence regarding the prognosis of mild DCM without surgical treatment, and conservative treatment seems a reasonable option, although patients need to be followed closely because some do deteriorate over time. Surgeons need to understand, however, the importance of decision making in the surgical management of mild DCM. PMID- 29173428 TI - Clinical Characteristics and Management of C3-4 Degenerative Cervical Myelopathy. AB - Single-level anterior cervical discectomy and fusion (ACDF) was performed at C3 4; non-C3-4 ACDF patients of the authors' random sample of ACDF patients were compared with C3-4 ACDF patients. The radiological study of C3-4 ACDF patients shows that they had significant cervical lordosis, and cervical motion was dependent on the C3-4 segment, which accounted for 39.8% of C2-7 range of intervertebral motion (total motion). In C3-4 ACDF patients, not only static factors but also dynamic factors (instability) at the C3-4 level contributed to the major causes of degenerative cervical myelopathy. PMID- 29173429 TI - Intraoperative Neurophysiologic Monitoring for Degenerative Cervical Myelopathy. AB - Multimodal intraoperative neurophysiologic monitoring is a reliable tool for detecting intraoperative spine injury and is recommended during surgery for degenerative cervical myopathy (DCM). Somatosensory evoked potential (SEP) can be used to monitor spine and peripheral nerve injury during positioning in surgery for DCM. Compensation technique for transcranial evoked muscle action potentials (tcMEPs) should be adopted in intraoperative monitoring during surgery for DCM. Free-running electromyography is a useful real-time monitoring add-on modality in addition to SEP and tcMEP. PMID- 29173430 TI - Health Economics and the Management of Degenerative Cervical Myelopathy. AB - Degenerative cervical myelopathy (DCM) is the leading cause of spinal cord impairment worldwide. Surgical intervention has been demonstrated to be effective and is becoming standard of care. Spine surgery, however, is costly and value needs to be demonstrated. This review serves to summarize the key health economic concepts as they relate to the assessment of the value of surgery for DCM. This is followed by a discussion of current health economic research on DCM, which suggests that surgery is likely to be cost effective. The review concludes with a summary of future questions that remain unanswered, such as which patient subgroups derive the most value from surgery and which surgical approaches are the most cost effective. PMID- 29173431 TI - Managing the Complex Patient with Degenerative Cervical Myelopathy: How to Handle the Aging Spine, the Obese Patient, and Individuals with Medical Comorbidities. AB - Degenerative cervical myelopathy (DCM) is the most common cause of nontraumatic spinal cord injury worldwide. Even relatively mild impairment in functional scores can significantly impact daily activities. Surgery is an effective treatment for DCM, but outcomes are dependent on more than technique and preoperative neurologic deficits. PMID- 29173432 TI - Future Directions and New Technologies for the Management of Degenerative Cervical Myelopathy. AB - The diagnosis and treatment of degenerative cervical myelopathy (DCM) has been evolving over the past 5 decades as a result of collaborations between clinicians and scientists. The most recent trends in basic and clinical research include advances in imaging, clinical diagnostic tools, molecular genetics, surgical techniques, and reparative/regenerative strategies. Spine surgeons are witnessing a fast-paced evolution, which is reshaping the management strategies available for an aging population that suffers increasingly from this degenerative condition. PMID- 29173433 TI - The Natural History of Degenerative Cervical Myelopathy. AB - Despite being the leading cause of spinal cord dysfunction among adults worldwide, little is known about the natural history of degenerative cervical myelopathy (DCM). There is mounting evidence of the effectiveness of surgery for DCM in halting progression of symptoms, and in fact, in improving neurologic outcomes, functional status, and quality of life. However, surgical decision making relies on a weighing of the risks and benefits of alternative strategies. We reviewed the available literature pertaining to the natural course of DCM and the predictors of outcome of nonoperative approaches. PMID- 29173434 TI - Imaging Evaluation of Degenerative Cervical Myelopathy: Current State of the Art and Future Directions. AB - Degenerative cervical myelopathy (DCM) is a common neurologic condition that is often treated with surgery. Imaging plays a central role in the management of DCM, including diagnosis, preoperative planning, postoperative assessment, and prognostication. Radiographs, CT, and MRI offer unique and complementary assessments, and all have important uses in current clinical practice. Emerging microstructural and functional MRI techniques have the potential to have a major impact, potentially transforming practice by offering earlier and more accurate diagnosis, monitoring for deterioration, and prediction of outcomes. In the future, it can be expected that imaging will play an even greater role in DCM management. PMID- 29173435 TI - Pathophysiology of Calcification and Ossification of the Ligamentum Flavum in the Cervical Spine. AB - Calcification of the ligamentum flavum (CLF) and ossification of the ligamentum flavum (OLF) in the cervical spine are differential diagnoses in patients with posterior extradural compressive lesions related to cervical degenerative disease. Preoperative computed tomography can facilitate the detection of characteristic findings and help to distinguish between CLF and OLF. Although these are rare entities in the cervical spine, adequately timed surgical decompression is required in most patients who present with radiculomyelopathy. PMID- 29173436 TI - Radiologic Evaluation of Ossification of the Posterior Longitudinal Ligament with Dural Ossification. AB - There are 3 basic radiological patterns of dural ossification (DO). Although double-layer DO is most common, when examining neuroimaging of ossification of the posterior longitudinal ligament (OPLL), isolated DO or masse DO should be kept in mind. Bone window computed tomography (CT) is most sufficient in identifying any type of DO associated with OPLL. Sagittal reformation of CT has replaced polytomography. MRI is not optimal for identification of DO and OPLL. Surgical approaches should be determined based on this important radiological information to avoid an unexpected complication. Expansive laminoplasty is the procedure of choice when DO is predominant. PMID- 29173437 TI - Ossification of the Ligaments in the Cervical Spine, Including Ossification of the Anterior Longitudinal Ligament, Ossification of the Posterior Longitudinal Ligament, and Ossification of the Ligamentum Flavum. AB - Ossification of the posterior longitudinal ligament (OPLL), ossification of the anterior longitudinal ligament (OALL), and ossification of the ligamentum flavum (OLF) sometimes are seen in the same patients, but the exact coexisting frequencies are not clear especially in the cervical region. The most frequent combination is OPLL and OALL. Cervical OPLL can coexist with thoracic OLF but is rarely associated with cervical OLF. All of these ossifying diseases of the cervical spinal ligaments are influenced by dynamic factors of the spinal column. The most frequent levels in the cervical spine affected by OPLL, OALL, and OLF are different because of anatomic differences inherent to each ligament. PMID- 29173438 TI - Importance of Sagittal Alignment of the Cervical Spine in the Management of Degenerative Cervical Myelopathy. AB - Cervical spine sagittal malalignment correlates with worse symptoms and outcomes in patients with degenerative cervical myelopathy (DCM), and should influence surgical management. An anterior versus posterior surgical approach may not significantly change outcomes in patients with preoperative lordosis; however, most studies suggest improved neurologic recovery among kyphotic patients after adequate correction of local sagittal alignment through an anterior or combined anterior-posterior approach. There are no comprehensive guidelines for DCM management in the setting of cervical malalignment; therefore, surgical management should be tailored to individual patients and decisions made at the discretion of treating surgeons with attention to basic principles. PMID- 29173439 TI - Anterior Cervical Option to Manage Degenerative Cervical Myelopathy. AB - Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord dysfunction in the world. There are multiple types of anterior approaches for treating patients with DCM. Many strategies have been developed to reduce complications for multilevel anterior surgery. Posterior approaches are sometimes used to supplement more extensive anterior approaches. More recently, multilevel cervical arthroplasty has been used for this condition. More data soon will be available comparing anterior and posterior approaches with the goal of optimizing patient-related quality of life and reducing complications, which include dysphagia, weakness, and instrumentation failure in some cases. PMID- 29173440 TI - Laminectomy with or Without Fusion to Manage Degenerative Cervical Myelopathy. AB - Stand-alone cervical laminectomy for degenerative cervical myelopathy (DCM) has become increasingly rare due to risk of postlaminectomy kyphosis. This article discusses the biomechanics of cervical degeneration and how laminectomy effects spine stability, and summarizes relevant clinical studies to help guide surgical decision-making for the posterior treatment of DCM. Laminectomy and fusion remains a safe and efficacious treatment. Stand-alone laminectomy should only be used for a highly selected patient population with relative stiff lordotic cervical spines, using care to not disrupt facets and C2 and C7 muscle attachments. PMID- 29173441 TI - Current Knowledge in Degenerative Cervical Myelopathy. PMID- 29173442 TI - Clinical diagnosis of idiopathic pleuroparenchymal fibroelastosis: A retrospective multicenter study. AB - BACKGROUND: Although the accurate diagnosis of pleuroparenchymal fibroelastosis (PPFE) requires pathologic evaluation, this diagnosis is often suggested when the radiologic findings are consistent with typical PPFE and when pulmonary apical cap, which radiologically and pathologically mimics PPFE, can be excluded by confirming disease progression. The aim of this study was to evaluate the validity of the clinical diagnosis of idiopathic PPFE. METHODS: We recruited 44 patients with idiopathic PPFE according to our modified diagnostic criteria: 1) a radiologic PPFE pattern (i.e., bilateral subpleural dense consolidation with or without pleural thickening in the upper lobes and less marked or absent involvement of the lower lobes), 2) radiologic confirmation of disease progression, and 3) exclusion of other lung diseases with identifiable etiologies. The patients' baseline characteristics and clinical course were reviewed. RESULTS: The median age was 70 years, and 28 patients were males. The majority revealed emaciation, hypercapnia, and a high ratio of residual volume to total lung capacity. On chest computed tomography, 39 patients showed abnormal shadows in the lower lobes; more than half were classified as having usual interstitial pneumonia (UIP)/possible UIP pattern. Pneumothorax was the most frequent complication (33/44). The median overall survival time after diagnosis was 35.3 months. The presence of lower lobe UIP/possible UIP pattern did not show a significant prognostic impact. CONCLUSIONS: Using our diagnostic criteria, we could recruit relatively many patients with similar characteristics to those of idiopathic PPFE patients in the literature. The possibility of clinical diagnosis of idiopathic PPFE should be further discussed. PMID- 29173443 TI - Omalizumab treatment for allergic bronchopulmonary aspergillosis in young patients with cystic fibrosis. AB - BACKGROUND: Allergic bronchopulmonary aspergillosis (ABPA) is a severe lung disease complication caused by an Aspergillus fumigatus-induced hypersensitivity that affects 2-15% of patients with cystic fibrosis (CF). The mainstay treatment consists of a combination of corticosteroids and antifungals. However, repeated or long-term corticosteroid therapies can lead to serious side effects. The monoclonal anti-IgE antibody, omalizumab, has demonstrated its efficacy in allergic asthma. As ABPA results from a hypersensitivity to a specific allergen, omalizumab might benefit CF patients with ABPA. Therefore, we conducted a retrospective study to investigate the effects of omalizumab on ABPA in CF patients. METHODS: We retrospectively analyzed the clinical records of young patients with CF treated with omalizumab for an ABPA in several French CF centers. The clinical data were collected 3 months before the start of omalizumab treatment, at initiation, and every 3 months up to 12 following initiation. These data comprised clinical, biological, nutritional, and functional parameters. RESULTS: Eighteen patients were included (mean age: 17.1 +/- 5.2 yrs). Under omalizumab was observed a stabilization of the lung function decline associated with a significant decrease in the corticosteroid daily dose (p = 0.0007) and an improvement in the nutritional status (p = 0.01). No serious side effect of omalizumab was reported. CONCLUSIONS: This study suggests that omalizumab might be an interesting therapeutic strategy in ABPA, associated with less side effects compared to long-term corticosteroids. Further randomized-controlled trials are needed to ascertain the efficacy of omalizumab in CF patients with ABPA. PMID- 29173444 TI - Combined effects of multiple risk factors on asthma in school-aged children. AB - BACKGROUND: Little is known about synergistic effects of several risk factors on asthma. We developed a risk score in Puerto Rican children, and then used this score to estimate the combined effects of multiple risk factors on asthma at school age in Puerto Rican and Swedish children. METHODS: Case-control study in 609 Puerto Rican children (aged 6-14 years) and longitudinal birth cohort study of 2290 Swedish children followed up to age 12 years (The Children, Allergy, Milieu, Stockholm, Epidemiological Survey [BAMSE] Study). In both cohorts, there was data on parental asthma, sex, obesity, allergic rhinitis, and early-life second-hand smoke (SHS); data on diet and (in children >=9 years) lifetime exposure to gun violence were also available in the Puerto Rico study. Asthma was defined as physician-diagnosed asthma and >=1 episode of wheeze in the previous year. RESULTS: In a multivariable analysis in Puerto Rican children, male sex, parental asthma, allergic rhinitis, early-life SHS, an unhealthy diet and (in children >=9 years) gun violence were each significantly associated with asthma. We next created a risk score using these variables (range, 0 to 5-6 in Puerto Rico and 0 to 4 in BAMSE). Compared with Puerto Rican children without any risk factors (i.e. a score of 0), Puerto Rican children with 2, 3, and at least 4 risk factors had 3.6 times (95% CI = 1.4-9.2), 10.4 times (95% CI = 4.0-27.0), and 21.6 times (95% CI = 7.2-64.9) significantly higher odds of asthma, respectively. In BAMSE, the presence of 2, 3, and at least 4 risk factors was significantly associated with 4.1 times (95% CI = 2.3-7.4), 6.3 times (95% CI = 3.0-13.3), and 17.2 times (95% CI = 4.1-73.2) increased odds of asthma at age 12 years. CONCLUSIONS: Our findings emphasize the multifactorial etiology of asthma, and suggest that concurrent eradication or reduction of several modifiable risk factors may better prevent or reduce the burden of childhood asthma. PMID- 29173445 TI - An international comparison of asthma, wheeze, and breathing medication use among children. AB - BACKGROUND: There is variation in childhood asthma between countries with typically higher prevalence in "Westernized" nations. We compared asthma, respiratory symptoms, and medication prevalence in Eastern and Central European regions and Canada. METHODS: We conducted a cross-sectional survey study of children (5-15 years) from one urban centre in each of Canada, Belarus, Poland, Republic of Georgia (Adjara), Republic of Macedonia, and Ukraine. Surveys were distributed through randomly selected schools to parents (2013-2015). RESULTS: The prevalence of asthma differed by country from 20.6% in Canada to 1.5% in Ukraine (p < 0.001). This association remained after confounder adjustment. Except for Canada (58.7%) and Poland (42.5%), less than 10% of children with a history of wheeze had a diagnosis of asthma. Regardless of country, more than 50% of children with a diagnosis of asthma used breathing medications in the past year. Finally, except for Georgia (12.1%), all countries had a prevalence of ever wheeze above 20% (23.8% in Poland to 30.9% in Macedonia). CONCLUSIONS: Despite large differences in asthma prevalence, respiratory morbidity was more comparable suggesting asthma prevalence may be underestimated. Further validation of asthma diagnosis is needed. It is important to promote best diagnostic practices among first contact physicians. PMID- 29173446 TI - Serum folate concentrations, asthma, atopy, and asthma control in Peruvian children. AB - BACKGROUND: The relationship between folate status and asthma-related outcomes has not been carefully examined in low- and middle-income countries where folate deficiency is common. METHODS: Ancillary analysis of an unmatched case-control study in which we analyzed serum folate concentrations in 412 children with asthma and 342 controls living in peri-urban communities in Lima, Peru. We examined baseline associations between folate and asthma, atopy, total serum IgE, pulmonary function, and fractional exhaled nitric oxide. We then followed children with asthma longitudinally for 6-9 months and assessed associations between folate and odds of uncontrolled asthma (defined as Asthma Control Test score <= 19) and of >=1 emergency visits during follow-up. RESULTS: A 10 ng/mL decrease in serum folate was associated with 45% higher adjusted odds of asthma (OR = 1.45, 95% CI 1.05-2.02). The folate-asthma relationship differed by atopic status: a 10 ng/mL decrease in serum folate was associated with a 2.4-fold higher odds of asthma among children without atopy (2.38, 1.20-4.72) and 23% higher odds of asthma in children with atopy (1.23, 0.85-1.80). Among children with asthma, a 10 ng/mL decrease in serum folate was associated with 62% higher odds of uncontrolled asthma (1.62, 1.02-2.56) and 73% higher odds of >=1 emergency visits during follow-up (1.73, 1.05-2.85). CONCLUSIONS: Serum folate concentrations were inversely associated with asthma, but this effect was stronger in children without atopy. Among children with asthma, lower serum folate concentrations were associated with higher risk of uncontrolled asthma. PMID- 29173447 TI - Clinical characteristics and treatment outcomes of pleural effusions in patients with nontuberculous mycobacterial disease. AB - BACKGROUND: The incidence of nontuberculous mycobacterial (NTM) infection has increased over the last 10 years. However, the clinical characteristics and treatment outcomes of patients with NTM pleuritis have not been well defined. METHODS: Patients with pleural effusion and NTM lung disease diagnosed between 1997 and 2013 were enrolled and their medical records were reviewed retrospectively. The subjects were divided into definite (n = 9, NTM isolated from the pleura or pleural effusion) and possible (n = 5, NTM lung disease with pleural effusion and improvement of effusion after anti-NTM treatment) groups. Clinical characteristics and treatment outcomes were analyzed. Patients with Mycobacterium avium complex (MAC) lung disease but without pleuritis were selected (the MAC-LD group) and compared with the MAC pleuritis (MAC-PD) group. RESULTS: The median age of the 14 NTM pleuritis patients was 68 years, and the majority were men (9/14, 64.3%). Mycobacterium intracellulare was the most common species detected (50.0%), followed by M. avium (35.7%), M. abscessus (7.1%) and M. kansasii (7.1%). The median lymphocyte frequency and adenosine deaminase level in the effusion were 83% and 97 IU/L, respectively. Eight patients successfully completed treatment, although 2 patients died as a consequence of uncontrolled NTM disease. The MAC-PD group had less nodular bronchiectatic lung features and a lower treatment success rate than the MAC-LD group. CONCLUSION: The laboratory characteristics of pleural effusions from patients with NTM disease were similar to those of patients with tuberculous pleuritis. The treatment outcome of MAC-PD appears to be worse than that of MAC-LD. Therefore, clinicians need to be alert to successfully manage patients with MAC-PD. PMID- 29173448 TI - Fractional exhaled nitric oxide and multiple breath nitrogen washout in preschool healthy and asthmatic children. AB - INTRODUCTION: Objectively assessing pulmonary disease is challenging in preschool children with asthma. We evaluated the feasibility of measuring fractional exhaled nitrogen oxide (FeNO) and multiple breath nitrogen washout (N2MBW) in children. We compared their capacities for discriminating between children with asthma and healthy controls. METHODS: We measured FeNO and N2MBW-derived indices of lung clearance (LCI2.5) and conductive and acinar ventilation heterogeneity (Scond and Sacin) in 65 preschool children; 35 with physician-diagnosed asthma and 30 healthy. FeNO was measured with a portable device (sampling time, 6 s). We employed data quality control guidelines on N2MBW. Feasibility was evaluated in a maximum of 8 attempts for both methods. Atopic co-morbidity and first-degree disposition were evaluated with the ISAAC-questionnaire. RESULTS: FeNO and N2MBW testing were feasible in 45% and 91% of children, respectively. Feasibility was highly age-dependent. In children under 4 years old, FeNO was not feasible, but N2MBW was 85% feasible. Children with asthma had significantly elevated Scond values (median; 95% CI) (0.024; 0.020; 0.029) compared to healthy controls (0.019; 0.016; 0.023), but similar FeNO, LCI2.5 and Sacinvalues. CONCLUSION: The feasibility of measuring FeNO was highly age-dependent and not applicable in children under age 4. N2MBW was feasible in the majority of preschool children. Scond, but not FeNO, could discriminate between children with asthma and healthy controls. PMID- 29173449 TI - Hyponatremia in infants with new onset moderate-severe bronchiolitis: A cross sectional study. AB - BACKGROUND: The reported cumulative prevalence of hyponatremia (sodium <135 mmol/L) in bronchiolitis is 28%. However, sodium level was never measured by direct potentiometry, the method recommended by the International Federation of Clinical Chemistry and Laboratory Medicine. Aim of this study was to assess the prevalence of hyponatremia, measured by direct potentiometry, in infants with moderate-severe bronchiolitis. METHODS: A prospective cross-sectional study was conducted in infants >=1month and <=24months of age with bronchiolitis. RESULTS: 160 consecutive infants were enrolled. Hyponatremia was observed in 91 (57%) patients and occurred more commonly in infants <=6 months than in older infant (P < 0.005). CONCLUSION: The first study on sodium level measured by the direct potentiometry in infants with bronchiolitis points out that the prevalence of hyponatremia is two-fold higher than so far reported. PMID- 29173451 TI - Editorial. PMID- 29173450 TI - Outcomes of pulmonary tuberculosis in patients with discordant phenotypic isoniazid resistance testing. AB - INTRODUCTION: The discrepancy rates of drug susceptibility testing (DST) results between solid and liquid media have been reported to range from 2.4 to 7.4% for isoniazid. Most isolate with isoniazid DST discrepancies between solid and liquid media test as susceptible on solid medium and resistant in liquid medium, however, the optimal management of patients with discordant testing is unknown. This study was conducted to evaluate the effect of treatment regimen on treatment outcomes when patients with rifampicin-susceptible pulmonary tuberculosis have isoniazid resistance (INH-R) in liquid medium but isoniazid susceptibility (INH S) on solid medium. METHOD: This study was retrospectively conducted by reviewing patient medical records on the liquid compared to solid culture based phenotypic testing at Samsung Medical Center between January 2009 and December 2015. The study population which have INH-R in liquid medium and INH-S on solid medium was divided into two groups: group A (n = 30), which included patients treated for INH-S tuberculosis by discontinuing pyrazinamide (and ethambutol), and group B (n = 56), which included patients treated for INH-R tuberculosis by continuing pyrazinamide and/or adding fluoroquinolone. Unfavorable outcomes included treatment failure and relapse. RESULTS: There were no statistically significant differences between the two groups including demographic data, comorbidities, radiologic data, and treatment duration. However, baseline smear positive rates were more frequent in group A (19/30, 63.3%) than in group B (22/56, 39.3%; P = 0.033). Only three patients had unfavorable outcomes; one was bacteriologically proven treatment failure and the other two were clinically judged as unfavorable outcomes. All of them were in the group A (3/30, 10%); no unfavorable outcomes occurred in the group B (0/56, 0%; P = 0.040). CONCLUSIONS: Unfavorable outcomes were less frequent in the group B than in the group A, indicating that treatment regimen modification according to DST results on liquid medium could improve treatment outcomes in patients with rifampicin-susceptible pulmonary tuberculosis. Further studies are required to confirm these findings to overcome the small number of unfavorable outcomes. PMID- 29173452 TI - Practical evaluation of an RNA-based saliva identification method. AB - Identifying saliva in samples found at crime scenes is important to clarify the tissue origin of DNA obtained for identification of individuals. Recently, a novel messenger RNA-based approach using two saliva-specific markers, Statherin (STATH) and Histatin 3 (HTN3), has been reported. This method can identify saliva more specifically than conventional amylase-based methods. Here, we performed several evaluations related to applying this method to real-world forensic work. First, we evaluated the effects of exposure to blue light (450nm) or to the reagent on Phadebas paper, which are direct methods used to locate saliva stains, on the stability of the RNA markers. The results demonstrate that exposure to the two direct tests did not affect the stability of the RNA markers. Second, we performed a comparative analysis of RNA-based and amylase-based conventional methods to examine the sensitivity and stability of the markers under various storage conditions. Although there was no difference in the sensitivity of the two methods for detecting 1-day-old saliva stains, a time-course study demonstrated that the RNA saliva markers were less stable than amylase, especially in wet conditions. During this time-course experiment, the stability of human DNA was also investigated. Although DNA was also unstable in wet conditions, it was more stable than the RNA markers in dry conditions. Taking the above results into consideration, we suggest that the RNA method could be introduced to current saliva identification procedures and should be used as a supplementary method to strongly support identification of saliva by the amylase based method. PMID- 29173453 TI - Design, optimisation and preliminary validation of a human specific loop-mediated amplification assay for the rapid detection of human DNA at forensic crime scenes. AB - The identification of samples at a crime scene which require forensic DNA typing has been the focus of recent research interest. We propose a simple, but sensitive analysis system which can be deployed at a crime scene to identify crime scene stains as human or non-human. The proposed system uses the isothermal amplification of DNA in a rapid assay format, which returns results in as little as 30min from sampling. The assay system runs on the Genie II device, a proven in field detection system which could be deployed at a crime scene. The results presented here demonstrate that the system was sufficiently specific and sensitive and was able to detect the presence of human blood, semen and saliva on mock forensic samples. PMID- 29173454 TI - Strengthening forensic DNA decision making through a better understanding of the influence of cognitive bias. AB - Cognitive bias may influence process flows and decision making steps in forensic DNA analyses and interpretation. Currently, seven sources of bias have been identified that may affect forensic decision making with roots in human nature; environment, culture, and experience; and case specific information. Most of the literature and research on cognitive bias in forensic science has focused on patterned evidence; however, forensic DNA testing is not immune to bias, especially when subjective interpretation is involved. DNA testing can be strengthened by recognizing the existence of bias, evaluating where it influences decision making, and, when applicable, implementing practices to reduce or control its effects. Elements that may improve forensic decision making regarding bias include cognitively informed education and training, quality assurance procedures, review processes, analysis and interpretation, and context management of irrelevant information. Although bias exists, reliable results often can be (and have been) produced. However, at times bias can (and has) impacted the interpretation of DNA results negatively. Therefore, being aware of the dangers of bias and implementing measures to control its potential impact should be considered. Measures and procedures that handicap the workings of the crime laboratory or add little value to improving the operation are not advocated, but simple yet effective measures are suggested. This article is meant to raise awareness of cognitive bias contamination in forensic DNA testing and to give laboratories possible pathways to make sound decisions to address its influences. PMID- 29173455 TI - Rapid identification information and its influence on the perceived clues at a crime scene: An experimental study. AB - Crime scenes can always be explained in multiple ways. Traces alone do not provide enough information to infer a whole series of events that has taken place; they only provide clues for these inferences. CSIs need additional information to be able to interpret observed traces. In the near future, a new source of information that could help to interpret a crime scene and testing hypotheses will become available with the advent of rapid identification techniques. A previous study with CSIs demonstrated that this information had an influence on the interpretation of the crime scene, yet it is still unknown what exact information was used for this interpretation and for the construction of their scenario. The present study builds on this study and gains more insight into (1) the exact investigative and forensic information that was used by CSIs to construct their scenario, (2) the inferences drawn from this information, and (3) the kind of evidence that was selected at the crime scene to (dis)prove this scenario. We asked 48 CSIs to investigate a potential murder crime scene on the computer and explicate what information they used to construct a scenario and to select traces for analysis. The results show that the introduction of rapid ID information at the start of an investigation contributes to the recognition of different clues at the crime scene, but also to different interpretations of identical information, depending on the kind of information available and the scenario one has in mind. Furthermore, not all relevant traces were recognized, showing that important information can be missed during the investigation. In this study, accurate crime scenarios where mainly build with forensic information, but we should be aware of the fact that crime scenes are always contaminated with unrelated traces and thus be cautious of the power of rapid ID at the crime scene. PMID- 29173456 TI - Recognition of computerized facial approximations by familiar assessors. AB - Studies testing the effectiveness of facial approximations typically involve groups of participants who are unfamiliar with the approximated individual(s). This limitation requires the use of photograph arrays including a picture of the subject for comparison to the facial approximation. While this practice is often necessary due to the difficulty in obtaining a group of assessors who are familiar with the approximated subject, it may not accurately simulate the thought process of the target audience (friends and family members) in comparing a mental image of the approximated subject to the facial approximation. As part of a larger process to evaluate the effectiveness and best implementation of the ReFace facial approximation software program, the rare opportunity arose to conduct a recognition study using assessors who were personally acquainted with the subjects of the approximations. ReFace facial approximations were generated based on preexisting medical scans, and co-workers of the scan donors were tested on whether they could accurately pick out the approximation of their colleague from arrays of facial approximations. Results from the study demonstrated an overall poor recognition performance (i.e., where a single choice within a pool is not enforced) for individuals who were familiar with the approximated subjects. Out of 220 recognition tests only 10.5% resulted in the assessor selecting the correct approximation (or correctly choosing not to make a selection when the array consisted only of foils), an outcome that was not significantly different from the 9% random chance rate. When allowed to select multiple approximations the assessors felt resembled the target individual, the overall sensitivity for ReFace approximations was 16.0% and the overall specificity was 81.8%. These results differ markedly from the results of a previous study using assessors who were unfamiliar with the approximated subjects. Some possible explanations for this disparity in performance were examined, and it was ultimately concluded that ReFace facial approximations may have limited effectiveness if used in the traditional way. However, some promising alternative uses are explored that may expand the utility of facial approximations for aiding in the identification of unknown human remains. PMID- 29173457 TI - Blast injury prevalence in skeletal remains: Are there differences between Bosnian war samples and documented combat-related deaths? AB - Court cases at the International Criminal Tribunal for the Former Yugoslavia (ICTY) have seen questions raised about the recognition and causes of blast related trauma and the relationship to human rights abuses or combat. During trials, defence teams argued that trauma was combat related and prosecutors argued that trauma was related to executions. We compared a sample of 81 cases (males between 18 and 75) from a Bosnian mass grave investigation linked to the Kravica warehouse killings to published combat-related blast injury data from World War One, Vietnam, Northern Ireland, the first Gulf War, Operation Iraqi Freedom and Afghanistan. We also compared blast fracture injuries from Bosnia to blast fracture injuries sustained in bombings of buildings in two non-combat 'civilian' examples; the Oklahoma City and Birmingham pub bombings. A Chi-squared statistic with a Holm-Bonferroni correction assessed differences between prevalence of blast-related fractures in various body regions, where data were comparable. We found statistically significant differences between the Bosnian and combat contexts. We noted differences in the prevalence of head, torso, vertebral area, and limbs trauma, with a general trend for higher levels of more widespread trauma in the Bosnian sample. We noted that the pattern of trauma in the Bosnian cases resembled the pattern from the bombing in buildings civilian contexts. Variation in trauma patterns can be attributed to the influence of protective armour; the context of the environment; and the type of munition and its injuring mechanism. Blast fracture injuries sustained in the Bosnian sample showed patterns consistent with a lack of body armour, blast effects on people standing in enclosed buildings and the use of explosive munitions. PMID- 29173458 TI - Can we continue to effectively police digital crime? AB - Now approximately 30years old, the field of digital forensics is arguably facing some of its greatest challenges to date. Whilst currently supporting law enforcement in numerous criminal cases annually, questions are beginning to emerge regarding whether it can sustain this contribution, with digital crime remaining prevalent. In his first live interview in September 2015, Head of MI5, Andrew Parker indicated that individuals are now engaging in computing acts which are beyond the control of authorities, confirming earlier remarks made by British Prime Minister David Cameron in the wake of the Charlie Hebdo attacks. Such comments cast doubt on the future effectiveness of the digital forensic discipline and its ability to effectively investigate those who implement the latest forms of technology to carry out illicit acts. This article debates the controversial question, could we be facing an era where digital crime can no longer be effectively policed? PMID- 29173459 TI - Conceptualising forensic science and forensic reconstruction. Part I: A conceptual model. AB - There has been a call for forensic science to actively return to the approach of scientific endeavour. The importance of incorporating an awareness of the requirements of the law in its broadest sense, and embedding research into both practice and policy within forensic science, is arguably critical to achieving such an endeavour. This paper presents a conceptual model (FoRTE) that outlines the holistic nature of trace evidence in the 'endeavour' of forensic reconstruction. This model offers insights into the different components intrinsic to transparent, reproducible and robust reconstructions in forensic science. The importance of situating evidence within the whole forensic science process (from crime scene to court), of developing evidence bases to underpin each stage, of frameworks that offer insights to the interaction of different lines of evidence, and the role of expertise in decision making are presented and their interactions identified. It is argued that such a conceptual model has value in identifying the future steps for harnessing the value of trace evidence in forensic reconstruction. It also highlights that there is a need to develop a nuanced approach to reconstructions that incorporates both empirical evidence bases and expertise. A conceptual understanding has the potential to ensure that the endeavour of forensic reconstruction has its roots in 'problem-solving' science, and can offer transparency and clarity in the conclusions and inferences drawn from trace evidence, thereby enabling the value of trace evidence to be realised in investigations and the courts. PMID- 29173460 TI - Conceptualising forensic science and forensic reconstruction. Part II: The critical interaction between research, policy/law and practice. AB - This paper builds on the FoRTE conceptual model presented in part I to address the forms of knowledge that are integral to the four components of the model. Articulating the different forms of knowledge within effective forensic reconstructions is valuable. It enables a nuanced approach to the development and use of evidence bases to underpin decision-making at every stage of a forensic reconstruction by enabling transparency in the reporting of inferences. It also enables appropriate methods to be developed to ensure quality and validity. It is recognised that the domains of practice, research, and policy/law intersect to form the nexus where forensic science is situated. Each domain has a distinctive infrastructure that influences the production and application of different forms of knowledge in forensic science. The channels that can enable the interaction between these domains, enhance the impact of research in theory and practice, increase access to research findings, and support quality are presented. The particular strengths within the different domains to deliver problem solving forensic reconstructions are thereby identified and articulated. It is argued that a conceptual understanding of forensic reconstruction that draws on the full range of both explicit and tacit forms of knowledge, and incorporates the strengths of the different domains pertinent to forensic science, offers a pathway to harness the full value of trace evidence for context sensitive, problem-solving forensic applications. PMID- 29173461 TI - Response paper to "The likelihood of encapsulating all uncertainty": The relevance of additional information for the LR. AB - In this response paper, part of the Virtual Special Issue on "Measuring and Reporting the Precision of Forensic Likelihood Ratios", we further develop our position on likelihood ratios which we described previously in Berger et al. (2016) "The LR does not exist". Our exposition is inspired by an example given in Martire et al. (2016) "On the likelihood of encapsulating all uncertainty", where the consequences of obtaining additional information on the LR were discussed. In their example, two experts use the same data in a different way, and the LRs of these experts change differently when new data are taken into account. Using this example as a starting point we will demonstrate that the probability distribution for the frequency of the characteristic observed in trace and reference material can be used to predict how much an LR will change when new data become available. This distribution can thus be useful for such a sensitivity analysis, and address the question of whether to obtain additional data or not. But it does not change the answer to the original question of how to update one's prior odds based on the evidence, and it does not represent an uncertainty on the likelihood ratio based on the current data. PMID- 29173462 TI - What should a forensic practitioner's likelihood ratio be? II. AB - In the debate as to whether forensic practitioners should assess and report the precision of the strength of evidence statements that they report to the courts, I remain unconvinced by proponents of the position that only a subjectivist concept of probability is legitimate. I consider this position counterproductive for the goal of having forensic practitioners implement, and courts not only accept but demand, logically correct and scientifically valid evaluation of forensic evidence. In considering what would be the best approach for evaluating strength of evidence, I suggest that the desiderata be (1) to maximise empirically demonstrable performance; (2) to maximise objectivity in the sense of maximising transparency and replicability, and minimising the potential for cognitive bias; and (3) to constrain and make overt the forensic practitioner's subjective-judgement based decisions so that the appropriateness of those decisions can be debated before the judge in an admissibility hearing and/or before the trier of fact at trial. All approaches require the forensic practitioner to use subjective judgement, but constraining subjective judgement to decisions relating to selection of hypotheses, properties to measure, training and test data to use, and statistical modelling procedures to use - decisions which are remote from the output stage of the analysis - will substantially reduce the potential for cognitive bias. Adopting procedures based on relevant data, quantitative measurements, and statistical models, and directly reporting the output of the statistical models will also maximise transparency and replicability. A procedure which calculates a Bayes factor on the basis of relevant sample data and reference priors is no less objective than a frequentist calculation of a likelihood ratio on the same data. In general, a Bayes factor calculated using uninformative or reference priors will be closer to a value of 1 than a frequentist best estimate likelihood ratio. The bound closest to 1 based on a frequentist best estimate likelihood ratio and an assessment of its precision will also, by definition, be closer to a value of 1 than the frequentist best estimate likelihood ratio. From a practical perspective, both procedures shrink the strength of evidence value towards the neutral value of 1. A single-value Bayes factor or likelihood ratio may be easier for the courts to handle than a distribution. I therefore propose as a potential practical solution, the use of procedures which account for imprecision by shrinking the calculated Bayes factor or likelihood ratio towards 1, the choice of the particular procedure being based on empirical demonstration of performance. PMID- 29173463 TI - The meaning of justified subjectivism and its role in the reconciliation of recent disagreements over forensic probabilism. AB - In this paper we reply to recent comments in this Special Issue according to which subjective probability is not considered to be a concept fit for use in forensic evaluation and expert reporting. We identify the source of these criticisms to lie in a misunderstanding of subjective probability as unconstrained subjective probability; a lack of constraint that neither corresponds to the way in which we referred to subjective probability in our previous contributions, nor to the way in which probability assignment is understood by current evaluative guidelines (e.g., of ENFSI). Specifically, we explain that we understand subjective probability as a justified assertion, i.e. a conditional assessment based on task-relevant data and information, that may be thought of as a constrained subjective probability. This leads us to emphasise again the general conclusion that there is no gap between justified (or, reasonable) subjective probability and other concepts of probability in terms of its ability to provide assessments that are soundly based on whatever relevant information available. We also note that the challenges an expert faces in reporting probabilities apply equally to all interpretations of probability, not only to subjective probability. PMID- 29173464 TI - Manganese modulates the physiological and biochemical responses of Mentha aquatica L. to ultraviolet radiation. AB - Ultraviolet (UV) radiation as an environmental factor alters the physiological and metabolic processes in plants. Manganese (Mn) is an essential element that is required for plant growth and development. This experiment was conducted in order to determine the effects of Mn supply and UV radiation on the physiological and metabolic responses in Mentha aquatica. With this aim, three levels of Mn and UV treatments were used as follows: basic Hoagland's nutrient solution without UV radiation (control), Mn supply (100MUM), UV radiation (2h daily), and UV+100MUM Mn. After three weeks of treatments, the root and shoot dry weights and the contents of photosynthetic pigments were decreased under UV radiation condition. However, the contents of flavonoids, soluble carbohydrate, anthocyanins, malonaldehyde (MDA), hydrogen peroxide (H2O2), and the activity of antioxidant enzymes (superoxide dismutase, catalase, and peroxidase) were increased. Interestingly, Mn at 100MUM concentration decreased the harmful effects of UV radiation on M. aquatica. In addition, the clear differences were observed in the terpene constituents of M. aquatica after the Mn and UV treatments. In this study, 1, 8-cineole, menthofuran and beta-caryophyllene were the most abundant constituents of essential oils in both the control and treated plants. The correlation analysis between pairs of the primary and secondary metabolites showed that there were positive and negative correlations among the variables under the Mn supply and UV radiation conditions. These findings clearly display a positive effect of external Mn up to 100MUM in the nutrient solution on the resistant of M. aquatica to UV radiation. PMID- 29173465 TI - The chemical speciation, spatial distribution and toxicity of mercury from Tibetan medicine Zuotai,beta-HgS and HgCl2 in mouse kidney. AB - Zuotai, a famous Tibetan medicinal mixture containing beta-HgS, has been used to combine with herbal remedies for treating diseases for more than 1 300 years. The target organ for inorganic mercury toxicity is generally considered to be the kidney. Therefore, it is crucial to reveal the chemical speciation, spatial distribution and potential nephrotoxicity of mercury from Zuotai in kidney. To date, this remains poorly understood. We used X-ray absorption spectroscopy (XAS) and micro X-ray fluorescence (MU-XRF) imaging based on synchrotron radiation to study mercury chemical forms and mercury special distribution in kidney after mice were treated orally with Zuotai, beta-HgS or HgCl2. Meanwhile, the histopathology of kidney was observed. Mice exposed with Zuotai showed kidney with significant proportion of mercury ions bound to sulfydryl biomolecules (e.g. Cys-S-Hg-S-Cys) plus some of unknown species, but without methylmercury cysteine, which is the same as beta-HgS and HgCl2. The mercury is mainly deposited in renal cortex in mouse treated with Zuotai, beta-HgS or HgCl2, but with a low level of mercury in medulla. The total mercury in kidney of mice treated with HgCl2 was much higher than that of beta-HgS, and the later was higher than that of Zuotai. And, HgCl2 cause severe impairments in mouse kidney, but that was not observed in the Zuotai and beta-HgS groups. Meanwhile, the bio-metals (Ca, Zn, Fe and Cu) micro-distributions in kidney were also revealed. These findings elucidated the chemical nature, spatial distribution and toxicity difference of mercury from Zuotai, beta-HgS and HgCl2 in mouse kidney, and provide new insights into the appropriate methods for biological monitoring. PMID- 29173466 TI - Nutritional management can assist a significant role in alleviation of arsenicosis. AB - Consumption of arsenic contaminated water causes serious skin disease and cancer in a significant number of exposed people. Chelating agents, consider an expensive therapy, are employed in the treatment of arsenic intoxication. There are reports which suggest that the poorest suffer the most from arsenicosis. This may be due to improper diet intake, consist of low protein and micronutrients which increase the vulnerability to arsenic-related disorders. Several human studies demonstrated the associations between malnourishment and the development of arsenic-caused skin lesions, skin cancer and cardiovascular effects. Thus, there is an urgent need of implementation of mitigation strategies for improving the health of exposed populations. Nutrition enhances the detoxification process so food rich in vitamins, protein, antioxidants help in its detoxification process. Methylation is the detoxification process which takes place via S adenosylmethionine (SAM). It is a methyl group donor and it derived its methyl group from diet. Nutritional intervention thus may appear as a practical and inexpensive approach. Nutrition provides protection from toxic effect of arsenic by two ways (i) methylation of As (ii) antioxidants which provides protection against free radical species. The governments and NGOs may run awareness programmes in arsenic affected area regarding prevention and alternate therapy which can decrease the susceptibility of the exposed population. They could also help in distributing cheaper, high protein diets particularly to the masses who cannot afford such foods. Thus, to prevent arsenicosis alternate therapy and proper nutrition could be the important strategy for alleviating its toxic effects. This mini review provides an insight on the importance of nutrition in preventing adverse effect cause by arsenic to suffer population. PMID- 29173467 TI - Augmentation of antioxidant and iron(III) chelation properties of tertiary mixture of bioactive ligands. AB - The excess of iron in plasma and cellular compartment pose direct and indirect toxic effects. In the present investigation, we proposed additive function of nutritional bioactive ligands in combination which has shown enhanced antioxidant and iron(III) chelation property. The optimal interaction and in vitro antioxidant activity of tertiary mixture comprising of curcumin+quercetin+gallic acid was validated by central composite design (CCD) based on ferric reducing antioxidant power assay (FRAP). The additive denticity of nutritional bioactive ligands was investigated by UV-vis, FTIR & MALDI-TOF-MS analysis, which has given substantial evidence for the formation of tris-bidentate [curcumin-quercetin gallic acid-Fe(III)] co-ordination complex. The in vivo proof of concept of the hypothesis was tested in iron intoxicated male wistar rats intoxicated with iron dextran. Co-administration curcumin+quercetin+gallic acid (CQG) exhibit dose dependent response & found effective in subsiding acute iron intoxication both at plasma and cellular level, evaluated by studies including serum ferritin, ICP OES, lipid peroxidation and histopathology studies among others. Thus, we conclude that in vitro and in vivo studies supported our hypothesis to deduce additive function nutritional ligands to counteract direct and indirect effects of iron(III). PMID- 29173468 TI - Spatially resolved quantification of gadolinium deposited in the brain of a patient treated with gadolinium-based contrast agents. AB - Due to its paramagnetic properties resulting from seven unpaired f-electrons, Gd is frequently applied in magnetic resonance imaging examinations. Due to the acute toxicity of free Gd3+, ligand ions based on polyaminocarboxylic acids are used to create thermodynamically stable linear or macrocyclic complexes. The highly water soluble Gd-based contrast agents (GBCAs) are known to be excreted fast and unmetabolized, mostly via the kidneys. Nevertheless, recent studies showed that Gd traces persists not only in animal but also in human brain. Aim of this study was the development and application of an analytical method for the spatially resolved quantification of gadolinium traces in human brain thin sections of a patient treated with GBCAs. For this retrospective study different human brain regions were selected to analyze the distribution of gadolinium. An additional patient served as control sample, as no GBCA was administered. Deep frozen brain thin sections were analyzed by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) and matrix-matched gelatin standards were prepared to quantify the gadolinium deposits via an external calibration. LA-ICP MS analyses with high spatial resolution showed gadolinium deposits in different brain regions with highest concentrations above 800ngg-1 more than two years after the last application of a GBCA. An excellent limit of quantification of 7ngg-1, which is far below the limits of detection of MRI methods, could be achieved. The found concentrations confirm recent reports on gadolinium depositions in human brain, which were obtained without high spatial resolution. LA-ICP-MS provides limits of quantification, which are well suited to detect ultratrace amounts of gadolinium in human brain. Therefore, it provides valuable information on the distribution of gadolinium traces in the human brain even after single administration of GBCAs. PMID- 29173469 TI - The possible protective effects of vitamin E and selenium administration in oxidative stress caused by high doses of glucocorticoid administration in the brain of rats. AB - Acute exposure to high doses of glucocorticoids (GCs) may potentially increase the basal levels of reactive oxygen species (ROS) by altering the defence capacity against oxidative damage. Also, antioxidants may affect the oxidative breakdown of tissues. Therefore, the aim of this work was to determine the effects of dietary intake vitamin E and selenium (Se) on lipid peroxidation (LPO) as thiobarbituric acid reactive substances (TBARS) and on the antioxidative defence mechanisms in the brain of rats treated with high doses of prednisolone. Two hundred and fifty adult male Wistar rats were randomly divided into five groups. The rats were fed a normal diet, but groups 3, 4, and 5 received a daily supplement in their drinking water of 20mg vitamin E, 0.3mg Se, and a combination of vitamin E and Se, respectively, for 30days. For 3days subsequently, the control (group 1) was treated with a placebo, and the remaining 4 groups were injected intramuscularly with 100mg/kg body weight (bw) prednisolone. After the last administration of prednisolone, 10 rats from each group were killed at 4, 8, 12, 24, and 48h and the activities of enzymes selenium-glutathione peroxidase (Se GSH-Px) and catalase (CAT), and the levels of reduced glutathione (reduced GSH) and TBARS in their brains were measured. Se-GSH-Px and CAT enzyme activities, and reduced GSH levels in the prednisolone treatment group (group 2) began to decrease gradually at 4h (p<0.01, p<0.05, respectively), falling respectively to 60, 50, and 40% of the control levels by 24h (p<0.001, p<0.01), and recovering to the control levels at 48h. In contrast, prednisolone administration caused an increase in the brain TBARS, reaching up to six times the level of the control at 24h (p<0.001). However, supplementation with vitamin E and Se had a preventive effect on the elevation of the brain TBARS and improved the diminished activities of antioxidative enzymes and the levels of reduced GSH. Therefore, the present study attempts to determine the sequence of cellular membrane damage in the brain of the rats after high doses GC administration and the possible roles in vivo of vitamin E and Se, and their combination. PMID- 29173470 TI - Effect of long-term aerobic, anaerobic and aerobic-anaerobic physical training in seric toxic minerals concentrations. AB - BACKGROUND: Many substances poured out from industries can be toxic to humans and can impair physical performance. Besides, physical training may modify the body concentrations of these substances as a result of physiological adaptations. OBJECTIVES: The aim of the study was to determine if different modalities of exercise might affect serum concentrations of toxic trace elements in sportsmen. METHODS: 80 Spanish national sportsmen were recruited before the start of their training period. All the athletes had been training regularly for the previous two years with a rigorous training target at high-level competition. 31 sedentary participants from the same geographic area formed the control group. Serum arsenic, beryllium, cadmium, cesium and lead samples were analyzed with an ICP MS. RESULTS: Serum concentrations were higher among the sportsmen group than among the control group, being highly significant in cases of Be from 0.043+/ 0.019 to 0.074+/-0.029MUg/L, Cs from 0.693+/-0.305 to 1.358+/-0.569MUg/L and Pb from 0.162+/-0.171 to 2.375+/-1.699MUg/L; and significant in the case of Cd from 0.046+/-0.027 to 0.067+/-0.059MUg/L. However, if they were separated according to different sport modalities, it was found that, although they had higher concentrations than controls, there were elements that changed their concentrations in relation to the metabolic type of activity performed. CONCLUSIONS: In some cases physical exercise induces favorable adaptations to avoid environmental pollution damage. Endurance training (65-75% VO2max) can be considered the most effective exercise to prevent toxicity effects. However, integral-matrixes analysis are required in further research to overcome some controversial behaviors of some elements. PMID- 29173471 TI - The combined effect of supplementary Cr(III) propionate complex and iron deficiency on the chromium and iron status in female rats. AB - The aim of the study was to evaluate the combined effect of supplementary chromium(III) and iron deficiency on the chromium and iron status in female rats. The study was carried out on female Wistar rats, which were divided into 6 experimental groups with different Fe levels (deficient 10% RDA and recommended (adequate) 100% RDA). Simultaneously, for six weeks their diets were supplemented with Cr(III) at doses of 1, 50 and 500mgkg-1. The tissular chromium and iron levels were measured with the AAS method. The serum iron and TIBC were measured with colorimetric methods The serum ferritin level was measured by means of electrochemiluminescence immunoassay. The serum transferrin level was measured with the ELISA method. The haematology was measured with an automated blood analyser. Supplementary Cr3 increased the Cr content in the tissues. This effect was weaker in the Fe-deficient groups than in those with the recommended Fe level, but it did not affect the Fe status. Fe deficiency significantly reduced the Fe content in the tissues. Simultaneously, Cr3 supplementation mitigated the symptoms of Fe deficiency. Fe deficiency increased TIBC and transferrin levels but reduced ferritin and most haematological parameters. However, simultaneous addition of high doses of Cr3 did not deepen these adverse changes. Our results show that the trend of changes in the Fe-Cr interaction depends on the content of these elements in the body. PMID- 29173472 TI - Levels of aqueous humor trace elements in patients with open-angle glaucoma. AB - PURPOSE: Trace elements might play a role in the complex multifactorial pathogenesis of open-angle glaucoma. The aim of this study was to analyze concentrations of trace elements in aqueous humor samples of patients with primary open-angle glaucoma (POAG) and pseudoexfoliation glaucoma (PEXG). PATIENTS AND METHODS: Thirty-three aqueous humor samples were obtained from patients undergoing cataract surgery: 12 patients with POAG (age 65.3+/-10.50, female 8, male 4), 10 patients with PEXG (age 65.9+/-11.27, female 6, male 4) and 11 patients without glaucoma (age 69.5+/-13.70, female 7, male 4) serving as controls. Aqueous humor levels of cadmium, iron, manganese, cobalt, copper and zinc were measured by Flow-Injection-Inductively-Coupled-Plasma-Mass-Spectrometry (FI-ICP-MS). RESULTS: From the statistical evaluation, we observed that patients with POAG had significantly higher aqueous humor levels of zinc (p=0.006) compared to controls. Increased aqueous humor levels of zinc were also observed in patients with PEXG in relation to control (p=0.0006). For iron we observed a significantly reduction in PEXG compared to control (p=0.002) and a significant difference between POAG and PEXG (p=0.0091). No significant differences were observed in aqueous humor levels of manganese, cobalt, copper, cadmium between glaucoma and control patients. No differences were seen for iron (POAG vs. controls). Analysis of trace element ratios was added. CONCLUSION: Significant differences in aqueous humor levels of zinc and iron between glaucoma and control patients support the hypothesis that these trace elements are involved in the pathogenesis of open-angle glaucoma. PMID- 29173473 TI - The importance of boron in biological systems. AB - Boron is an essential element for plants and probably essential for human and animal health. Boron has a broad range of physiological effects on biological systems at low concentrations, whereas it is toxic to at high concentrations. Eventhough there are many studies on boron's biological effects and toxicity, more information is needed to understand the mechanisms of its action. The aim of the current work is to review boron's function, transport and toxicity in different biological systems. PMID- 29173474 TI - Metallothionein 2A gene polymorphism and trace elements in mother-newborn pairs in the Croatian population. AB - The main source of exposure for all essential and toxic elements in the general population is diet. In smokers, the main route for cadmium (Cd) and lead (Pb) intake is the inhalation of tobacco smoke. Besides gender, age, nutrition, lifestyle, and physiological conditions such as pregnancy, specific genetic characteristics also influence individual element uptake. Metallothionein MT2 is a cysteine-rich low-weight protein found ubiquitously throughout the body. Specific gene polymorphism may influence MT2 expression and subsequent binding, transfer and organ accumulation of metals, though data on these influences are lacking, especially in human mother-newborn pairs. The objective of this study was to determine selected toxic (Cd, Pb, Hg) and essential (Fe, Zn, Cu, Se) elements in maternal blood, placenta, and cord blood (by ICP-MS), and MT2 levels in maternal serum (by ELISA) in relation to maternal MT2A -5A/G (rs28366003) polymorphism (by RFLP-PCR and electrophoresis). Study participants were healthy postpartum women in Croatia (n=268, mean age 29 years) with term vaginal childbirth in a maternity ward assigned into two study groups by self-reporting about their smoking habit (by questionnaire). Smokers vs. non-smokers had increased levels of Cd and Pb in all measured samples, Fe and Cu in cord blood, Zn in placenta, and MT2 in maternal serum. Among subjects with AG/GG genotype, placental Fe was significantly lower only among non-smokers, while MT2 levels in serum were lower, though not significantly, regardless of maternal smoking habit. There was no impact of MT2A -5A/G SNP on any element in maternal or cord blood. In conclusion, the results confirmed maternal smoking-related increases in Cd and Pb levels in the maternal-placental-foetal unit. They also provided additional data on concomitant metal concentrations in representative samples of maternal blood, placenta, and cord blood, as well as increased cord blood Fe and Cu, placental Zn, and maternal serum MT2 in smokers. New evidence is that MT2A -5A/G SNP was associated with decreased placental Fe levels in non-smokers. For a final conclusion on the influence of the MT2A -5A/G polymorphism on toxic and essential element levels in mother-newborn pairs, further research would require a larger number of participants divided across subgroups defined by the main source of particular toxic metal exposure (such as specific food intake, cigarette smoking, air pollution and/or occupational exposure). PMID- 29173475 TI - Mechanism of insulin-like effect of chromium(III) ions on glucose uptake in C2C12 mouse myotubes involves ROS formation. AB - Chromium is considered a trace element which improves glucose tolerance, but mechanism accounting for this insulin-like action is not recognized. The main purpose of this study was to examine the role of reactive oxygen species (ROS) in chromium and insulin stimulated glucose transport using antioxidants. Effect of chromium ions on phosphatases, enzymes involved in inhibition of insulin signaling was also investigated. Experiments were performed in vitro on C2C12 mouse myotubes. ROS level was measured with the use of confocal microscope and 2',7' dichlorodihydrofluorescein diacetate (DCFH-DA). Glucose metabolism was assayed by the measurement of 2-[3H]-deoxyglucose uptake. Cr3+ ions and insulin treatment caused significant increase of ROS formation and also stimulated glucose uptake in C2C12 cells in concentration dependent manner. Antioxidants (L ascorbic acid and N-acetyl cysteine 100MUM) and DPI (diphenyleneiodonium-NADPH oxidase inhibitor, 10MUM) abolished insulin- and Cr-inducted glucose transport. Our results confirm the hypothesis that the ROS are integral part of insulin signaling pathway and that the insulin mimetic effect of Cr3+ ions depends on the antioxidant status of the cells. Surprisingly, chromium treatment resulted in increased activity of membrane phosphatases. PMID- 29173476 TI - Free copper in serum: An analytical challenge and its possible applications. AB - Copper (Cu), as an essential metal, plays a crucial role in biochemical reactions and in physiological regulations. Cu in plasma is mostly bound to proteins; about 65-90% of Cu is tightly binds with caeruloplasmin and the rest of Cu is loosely binds with albumin and transcuprein. A small but significant relatively "free" fraction, probably complexed with amino acids, is present at around 5% of the total concentration. We developed and validated a new method for direct measurement of free Cu in serum by ultrafiltration with AMICON(r)Ultra 100K device and determination with AAS. Also, we checked that there is no trace of albumin in the ultrafiltrates and we demonstrated the ultrafiltration of a known concentration of Cu added in artificial serum without albumin and, on the contrary, the retention of the Cu in artificial serum with albumin. The ultrafiltration procedure and the instrumental determination showed a good repeatability and a very low limit of detection (1MUg/L). The method was applied to 30 healthy subjects, the mean value of the total Cu (994.8MUg/L) is included in the normal range for healthy people and the values of free Cu (23.6MUg/L) corresponding to 2.37% of the Cu total. The determination of free Cu by this simple and cheap method may be useful to measure the most bioavailable Cu fraction possibly implicated in neuro-degenerative and oxidative-stress related diseases. PMID- 29173477 TI - Copper dyshomeostasis in Wilson disease and Alzheimer's disease as shown by serum and urine copper indicators. AB - Abnormal handling of copper is the cause of Wilson disease (WD), a rare disorder typified by increased levels in plasma copper not-bound to ceruloplasmin (nCp-Cu, also known as 'free' copper). In Alzheimer's disease (AD), meta-analyses show that copper decreases in brain but increases in serum, due to the nCp Cu component increase. Despite the similarities, a direct comparison of copper biological status in the two diseases has never been carried out. To fill this gap, we evaluated serum copper, ceruloplasmin, nCp-Cu and Cu:Cp in 385 CE and 336 healthy controls previously investigated that were compared with 9 newly diagnosed WD patients. We then assessed 24h copper urinary excretion in 24 WD patients under D-penicillamine (D-pen) treatment and in 35 healthy controls, and compared results with those of AD patients participating to a D-pen phase II clinical trial previously published. After adjusting for sex and age, serum nCp Cu and Cu:Cp resulted higher in AD and in WD than in healthy controls (both p<0.001). While nCp-Cu was similar between AD and WD, Cu:Cp was higher in WD (p<0.016). 24h urinary copper excretion in AD patients (12.05MUg/day) was higher than in healthy controls (4.82MUg/day; p<0.001). 77.8% of the AD patients under D pen treatment had a 24h urinary excretion higher than 200MUg/day, suggestive of a failure of copper control. This study provides new insight into the pathophysiology of copper homeostasis in AD, showing a failure of copper control and the Cu:Cp ratio as an eligible marker.

PMID- 29173479 TI - Trace elements in struvite equine enteroliths: Concentration, speciation and influence of diet. AB - Equine enteroliths ~1.5cm in diameter were collected from an Arabian horse in Louisville, Kentucky, United States. Scanning electron microscopy (SEM) and light microscope imaging of a sectioned enterolith showed two distinct regions of concentric growth outward from the central nidus, a small pebble. After initial growth, acidic colonic fluids permeated the stone inducing recrystallization and alteration of crystals closest to the nidus. A second growth event, when mineral crystallization was again favorable, produced an outer region of unaltered crystals at the rim. The mineral was identified as struvite (MgNH4PO4?6H2O) by powder X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. Elemental analysis confirmed concentrations of P, Mg and N consistent with the struvite composition, and detected trace elements Fe (1050 1860mgkg-1), Mn (262-280mgkg-1) and Zn (197-238mgkg-1). All elements were traced to dietary sources, with the Fe:Mn:Zn ratio of the enterolith consistent with that of the horse feed. X-ray absorption fine structure (XAFS) spectroscopy at the Zn K-edge revealed distorted ZnO4 tetrahedra located between crystallographic planes in the struvite structure forming bidentate linkages to struvite phosphate groups. Emplacement of Zn in structural cavities likely occurs during struvite crystallization. Trace elements and organic impurities increase susceptibility of the enterolith to heat-induced decomposition relative to pure struvite, which could be a consideration for treatment. Results reveal enterolith growth processes, composition and mechanisms of trace metal accumulation that can inform management and prevention of equine enteroliths. PMID- 29173480 TI - Changed expressions of N-methyl-d-aspartate receptors in the brains of rats and primary neurons exposed to high level of fluoride. AB - Expressions of N-methyl-d-aspartic acid receptors (NMDARs) in the brains of rats and primary neurons exposed to high fluoride were investigated. Sprague-Dawley rats were divided randomly into a fluorosis group (50ppm fluoride in the drinking water for 6 months) and controls (<0.5ppm fluoride) and the offspring from these rats sacrificed on postnatal days 1, 7, 14, 21 and 28. The primary cultured neurons from the hippocampus of neonatal rats were treated with 5 and 50ppm fluoride for 48h. NMDAR subunits at protein or mRNA levels were quantified by Western blotting or real-time PCR. The phosphorylated calmodulin-protein kinase II (CaMKII) was determined by Western blotting, concentration of Ca2+ in neurons by laser confocal microscopy and apoptosis by flow cytometry. In the brains of adult rats and pups as well as in primary neurons exposed to high fluoride, the mRNAs encoding GluN1 and GluN2B subunits and the corresponding proteins were elevated, the GluN3A lowered and the GluN2A unchanged. In addition, the level of phosphor-CaMKII was reduced, and Ca2+ influx and apoptosis enhanced in the brains of rats and cultured neurons exposed to high fluoride. The results indicate that such modifications may involve brain damage induced by chronic fluorosis. PMID- 29173482 TI - Excessive iodine status among Saharawi refugees. PMID- 29173481 TI - Manganese in blood cells as an exposure biomarker in manganese-exposed workers healthy cohort. AB - Elevated exposure to manganese (Mn) has long been a public health concern. However, there is currently no consensus on the best exposure biomarker. Here we aimed to investigate the exposomic characteristics of plasma metals among Mn exposed workers and explore the potential biomarkers of Mn exposure in the blood pool. First, total sixteen plasma metals (Calcium, Magnesium, Iron, Zinc, Copper, Selenium, Lead, Chromium, Arsenic, Manganese, Nickel, Molybdenum, Cadmium, Mercury, Thallium, and Cobalt) were determined among 40 occupationally Mn-exposed subjects. Second, Mn levels in both plasma and blood cells were detected among 234 workers from the manganese-exposed workers healthy cohort (MEWHC), respectively. Analysis of plasma metal exposome showed that the plasma Mn concentrations were positively correlated to plasma Fe (r=0.361), Ni (r=0.363), Cr (r=0.486), and Hg (r=0.313) (all p<0.05). Mn concentrations in plasma were not significantly correlated to external exposure levels (ptrend=0.200), and it was further confirmed among the 234 subjects (ptrend=0.452). However, Mn concentrations in blood cells progressively increased as the external exposure dose increased (low-exposure group vs high-exposure group, median 11.53MUg/L vs 20.41MUg/L, ptrend=0.001). Our results suggest that Mn in blood cells, but not plasma, could serve as a potential internal exposure biomarker. Larger validation studies are needed to establish the utility of this biomarker. PMID- 29173483 TI - Assessing the boron nutritional status by analyzing its cummulative frequency distribution in the hair and whole blood. AB - Boron is a non-essential ubiquitous trace element in the human body. The aim of this study was to assess boron nutritional status by analyzing boron frequency distribution in the long-term biological indicator tissue of hair and the short term biological indicator of whole blood. Hair samples were analyzed in 727 apparently healthy subjects (263 ? and 464 ?) and the whole blood boron was analyzed in the random subsample of them (80 ? and 152 ?). Samples were analyzed by the ICP-MS at the Center for Biotic Medicine, Moscow, Russia. The adequate reference range for hair boron concentration was (MUg?g-1) 0.771- 6.510 for men and distinctly lower 0.472-3.89 for women; there was no detectable difference in the whole blood boron for the adequate reference range between men (0.020-.078) and women (0019-0.062). Boron may play an essential role in the metabolism of the connective tissue of the biological bone matrix. PMID- 29173484 TI - Strontium and oxidative stress in normal pregnancy. AB - BACKGROUND: Pregnancy brings about metabolic and oxidative changes that involve various trace elements and oxidative stress. Strontium (Sr) is a trace element scarcely studied in this context, although it has been suggested that it may play a role in the pathophysiology of preeclampsia. The main aim of this study was to evaluate Sr concentrations and oxidative status in normal pregnancy. METHODS: The study population included non-pregnant women (n=31), healthy pregnant women in the first (n=50), second (n=51) and third (n=53) trimesters of gestation, and women in postpartum period (n=31). Additionally, samples from another twenty pregnant women were obtained in the three trimesters. Strontium, copper, selenium and zinc were measured by inductively coupled plasma-mass spectrometry. Calcium (Ca), uric acid (UA), lipid peroxidation and total antioxidant activity (TAA) were measured by spectrophotometric assays. RESULTS: Strontium remained unchanged until the third trimester of pregnancy, in which significantly higher levels were found (p=0.001). The other elements showed diverse trends during pregnancy. Uric acid levels were significantly different in all groups (p<0.001), increasing gradually as the pregnancy progresses. In serial samples, there was a statistically significant positive correlation between Sr and gestational week of sampling (r=0.31, p=0.01), UA (r=0.40, p=0.001) and lipid peroxidation/TAA ratio (r=0.38, p=0.0002). Additionally, Sr correlated negatively with TAA (r=-0.40, p=0.0001). CONCLUSION: Strontium seems to play a physiological role in the oxidative status of the human organism. Further studies involving Sr and pathologies of pregnancy are warranted. PMID- 29173485 TI - High serum selenium levels are associated with impaired fasting glucose and elevated fasting serum glucose in Linyi, China. AB - BACKGROUND: The relationship between selenium level and impaired fasting glucose or elevated fasting serum glucose remains controversial. This study aimed to evaluate these associations in China. METHODS: This observational population study adopted a cluster sampling approach to enroll participants. Baseline information on selenium categories was tested using one-way analysis of variance and Kruskal-Wallis equality-of-populations rank tests. Multivariable logistic regression was used to investigate the association between serum selenium level and impaired fasting glucose or elevated fasting serum glucose. RESULTS: The mean serum selenium concentration was 121.5MUg/L which in a relatively high baseline Se status. Differences were observed among individuals with normal, impaired fasting glucose and elevated fasting serum glucose levels in their basic information, physical examination results and laboratory findings. After adjusting for their basic information, physical examination results and laboratory findings, compared with the low-selenium group, the high-selenium groups (124.9-143.9 and above 143.9MUg/L) had ORs for elevated fasting serum glucose of 2.31 (1.37-3.90) and 2.67 (1.59-4.48), respectively (both P<0.05). A sex-difference was observed, and a significant association between selenium levels and impaired fasting glucose was observed for males but not for females. CONCLUSIONS: The findings of this observational study suggest that relatively high selenium levels might be positively associated with elevated fasting serum glucose and relatively high selenium levels might be positively associated with impaired fasting glucose in men. PMID- 29173486 TI - Liver tissue trace element levels in HepB patients and the relationship of these elements with histological injury in the liver and with clinical parameters. AB - AIM: In this study, the relationship of liver tissue trace element concentrations with hepatitis B disease and the effects of several environmental factors were analysed. METHOD: The liver tissue concentrations of Al, Fe, Cd, Mn, Cr, Cu, Pb, Ni, Zn, Ag, and Co were evaluated in 92 patients with hepatitis B using the Inductively Coupled Plasma - Mass Spectrometry (ICP/MS) method in the analyses. The patients were divided into the following two groups: low-high Ishak histologic activity index (HAI) (0-6: Low Histologic Activity, 7-18: High Histologic Activity) and low-high fibrosis (FS) (Fibrosis 1,1,2 and Fibrosis 3,4,5,6). The metal levels were compared between the groups. RESULTS: The Cd concentration was found to be statistically higher in the group with low HAI scores (p=0.019). The hepatic Cu concentration was found to be higher in women than in men (p=0.046). The hepatic Fe concentration was found to be higher in the group with increased FS compared to the group with decreased FS (p=0.033). Cd was found to be higher in patients who worked in positions involving exposure to heavy metals and in individuals with an ALT level above 40 IU/L (p=0.008). Several correlations have been found between the hepatic tissue metal levels in our study. In a linear regression analysis, Fe and Zn were found to be correlated with the fibrosis scores (p=<0.001 and p=0.029), and Cu was correlated with HAI (p=0.023). In the linear regression model, Ni (p=0.018) and Cr (p=0.011) were correlated with gender. There was a correlation between the hepatic Fe level and the location where hepatitis B patients were living (village/city) (p=0.001), frequency of fish consumption (p=0.045) and smoking (p=0.018) according to the linear regression analysis. Using a logistic regression analysis, Cr (p=0.029), Ni (p=0.031) and Pb (p=0.027) were found to be correlated with smoking habit, and Zn (p=0.010), Ag (p=0.026), Cd (p=0.007) and Al (p=0.005) were correlated with fish consumption. CONCLUSION: The liver tissue trace element levels are correlated with disease activity and histologic damage in patients with HepB disease. Additionally, smoking, the environment in which the patient works and the amount of fish consumption affect the accumulation of trace elements in the liver. PMID- 29173488 TI - Multi-elemental composition and antioxidant properties of strawberry tree (Arbutus unedo L.) honey from the coastal region of Croatia: Risk-benefit analysis. AB - The concentration of 23 major and trace elements, total phenolic content (TPC) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity were determined in nine samples of strawberry tree honey and compared to other types of unifloral honeys. The most abundant elements in strawberry tree honey were potassium, calcium, magnesium and sodium, ranging between 1276 and 2367, 95.2 154, 14.4-74.4 and 13.4-64.3mg/kg, respectively. Strawberry tree honey had generally higher TPC (range: 0.314-0.522g GA/kg) and DPPH (1.94-4.45mM TE/kg) compared to other analysed unifloral honeys. A strong positive relationship was found between TPC and DPPH, TPC and concentration of homogentisic acid (HGA), chemical marker of strawberry tree honey, and between DPPH and HGA. Regarding daily intake of essential elements, strawberry tree honey can be considered nutritionally richer than the majority of unifloral honeys available in Croatia, while contribution to tolerable intake set for potentially toxic elements was very low, corresponding to pristine areas. PMID- 29173487 TI - Serum and whole blood Zn, Cu and Mn profiles and their relation to redox status in lung cancer patients. AB - Disturbed redox status may be critical to lung cancerogenesis, however little research has been conducted on general changes in total redox status in lung cancer. Levels and activities of antioxidants, especially enzymatic ones, are related to trace element concentration. Trace element status is often disturbed in cancers, however no studies concerning the association between redox and trace element status have been performed for lung cancer. We hypothesized that disturbed redox status in lung cancer patients is partially determined by trace elements while their distribution amongst blood compartments may differ compared to healthy subjects. Blood samples from lung cancer patients (n=44) and control subjects (n=44) were collected to assess redox and trace element status. Serum and whole blood Cu and Mn levels were determined with GF-AAS, and Zn-with F-AAS. In serum the total antioxidant status (TAS) was determined with the commercial kit TAS (Randox, UK), total oxidant status (TOS) was determined based on the method developed by Erel and the oxidative stress index (OSI) was calculated. Total protein (T-Prot), albumin (Alb), uric acid (UA) and total bilirubin (T-Bil) concentrations were measured with an auto-analyser (Konelab 20i, Thermoscientific, USA), SOD and CAT activity - with commercially available kits (Cayman, USA). The level of TAS, T-Prot, Alb, T-Bil, the activity of SOD, the concentration of whole blood Mn as well as serum and whole blood Zn were lower while TOS, OSI, serum Cu levels and serum Cu:Zn ratios were higher in lung cancer patients compared to the control group. In the lung cancer group TAS correlated positively with Alb and UA, serum Zn and negatively with whole blood Mn. Additionally, SOD positively correlated with the whole blood Mn and Cu:Zn ratio, while CAT - negatively with the whole blood Cu:Zn ratio. In the lung cancer sub group at clinical stage I-II, TOS additionally negatively correlated with whole blood Zn, and CAT negatively with serum Cu and Cu:Zn ratio. In advanced lung cancer, we found a positive correlation between TAS and serum Zn, and a negative one - with serum Cu:Zn ratio. We observed a similar correlation between endogenous non-enzymatic antioxidants and TAS in the control group, however considerably fewer correlations between trace elements and antioxidants were observed. This study supports the hypothesis that disturbed redox status in lung cancer patients is linked with alterations in trace element status regarding Zn, Mn and Cu. Moreover, the type of biological fluid influences both - alterations in the metal profile and relationships with redox status parameters. PMID- 29173489 TI - Bacterial exopolysaccharide (EPS)-coated ZnO nanoparticles showed high antibiofilm activity and larvicidal toxicity against malaria and Zika virus vectors. AB - In this study, a novel and effective approach was performed to synthesize ZnO nanoparticles (ZnO NPs) using the exopolysaccharides (EPS) from the probiotic strain Bacillus licheniformis Dahb1. EPS acted as reducing and stabilizing agent for the formation of EPS-ZnO NPs by co-precipitation method. Structural characterization was investigated by a surface plasma resonance centered at 375nm in UV-vis spectrum. FTIR spectrum exhibited functional groups with strong absorption peak at 3814.7-420cm-1. XRD showed the crystalline nature of EPS-ZnO NPs. TEM showed that the EPS-ZnO NPs were hexagonal in shape, with size within the range of 10-100nm. The presence of Zn was confirmed by EDX analysis. Antibacterial activity of EPS-ZnO NPs was demonstrated as 100MUg/ml significantly inhibited the effective growth control of Gram-negative (Pseudomonas aeruginosa and Proteus vulgaris) and Gram-positive (Bacillus subtilis and Bacillus pumilus) bacteria. Light microscopy and confocal laser scanning microscopy evidenced that the antibiofilm activity of EPS-ZnO NPs was higher against Gram-negative bacteria over Gram positive bacteria. EPS-ZnO NPs also inhibited the biofilm growth of Candida albicans at the concentration of 75MUg/ml. The hemolytic test showed low cytotoxicity of EPS-ZnO NPs at 5mg/ml. In addition, EPS-ZnO NPs achieved 100% mortality against third instars mosquito larvae of Anopheles stephensi and Aedes aegypti at very low doses. Moreover, histology studies revealed the presence of damaged cells and tissues in the mid-gut of treated mosquito larvae. The multipurpose properties of EPS-ZnO NPs revealed in the present study can be further considered for pharmaceutical, parasitological and entomological applications.

PMID- 29173494 TI - The lymphocyte cytokinesis block micronucleus test in human populations occupationally exposed to vinyl chloride: A systematic review and meta-analysis. AB - Vinyl chloride (VC) is widely used in industry in the production of polyvinyl chloride (PVC), which is used to manufacture a large variety of materials. VC was classified as a known (Group 1) human carcinogen by IARC on the basis of increased risk for liver angiosarcoma and hepatocellular cancer, and the carcinogenicity of VC was shown to be mediated by a genotoxic mechanism. Following inhalation, the compound is rapidly absorbed and metabolized in the liver to the electrophilic metabolites chloroethylene-oxide and chloroacetaldehyde, which form DNA adducts that can be processed into point mutations in cancer-related genes detected in humans and rats exposed to VC. A number of genotoxicity biomarkers were applied in workers exposed to VC to detect early biological responses associated with the carcinogenesis process. The present systematic review analyzed the published studies in which the cytokinesis block micronucleus assay in peripheral lymphocytes (L-CBMN) was applied in VC exposed subjects. Thirteen out of fifteen retrieved studies performed in China showed increased MN frequencies (FR 1.92-3.98) associated with increased cumulative exposure or employment time. Twofold and more than threefold increases were detected in PVC-exposed workers exposed to a mean of 50ppm of VC in the former Yugoslavia and in South India, respectively. The meta-analysis of MN frequency from six eligible studies confirmed this tendency (pooled MR 2.32 - 95% CI 1.64-3.27). The benchmark dose lower limit for 10% excess risk (BMDL 10) calculated from three studies resulted in an estimated exposure limit of 0.03 0.07mg/m3. Overall the results of this review showed the need for further studies, especially because PVC products from China may contain high levels of uncoupled VCM that could represent a source of exposure to workers and consumers. Moreover, the results underline the importance of re-evaluating the recommended exposure limits using new biomonitoring methods in addition to MN. PMID- 29173495 TI - Inflammation and the chemical carcinogen benzo[a]pyrene: Partners in crime. AB - Exposure to benzo[a]pyrene (B[a]P) is known to play a role in lung carcinogenesis and the underlying processes can be modified by the presence of inflammation. The inflammatory process can for instance enhance the concentration of reactive metabolites that bind to DNA and may also diminish DNA repair. Additionally, during the inflammatory process mediators are released that create a microenvironment which is suitable for further stimulation of cancer development. Various transcriptional pathways are activated by inflammation, including pathways that are mediated via nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB), signal transducer and activator of transcription 3 (STAT-3), and hypoxia-inducible factor-1 (HIF-1). Crosstalk between these pathways and the aryl hydrocarbon receptor (AhR) occurs at multiple levels and thereby boosts B[a]P induced carcinogenesis. This review focuses on inflammatory mediators, including cytokines, chemokines and extracellular enzymes that modulate molecular events in B[a]P induced cancers. PMID- 29173496 TI - The interaction of iron and the genome: For better and for worse. AB - Iron, as an essential nutrient, and the DNA, as the carrier of genetic information which is physically compacted into chromosomes, are both needed for normal life and well-being. Therefore, it is not surprising that close interactions exist between iron and the genome. On the one hand, iron, especially when present in excess, may alter genome stability through oxidative stress, and may favor cell cycle abnormalities and the development of malignant diseases. The genome also receives a feedback signal from the systemic iron status, leading to promotion of expression of genes that regulate iron metabolism. Conversely, on the other hand, DNA mutations may cause genetic iron-related diseases such as hemochromatosis, archetype of iron-overload diseases, or refractory iron deficiency anemia (IRIDA). PMID- 29173497 TI - Breast cancer genetics in young women: What do we know? AB - Breast cancer (BC) in young women, generally defined in oncology as women who are 40 years of age or younger, represents 2 out of 10 BC cases in developing countries. Several research studies, including genetic cancer panel tests, genome wide association studies, expression analyses and polymorphisms reports, have found that young women with BC exhibit a higher genetic susceptibility and specific genomic signature compared to postmenopausal women with BC. Thus, international guidelines recommend genetic counseling for this age population. This review presents the current state of the art of genetics and genomics with regards to young women with BC. PMID- 29173498 TI - Carcinogenic potential of sanguinarine, a phytochemical used in 'therapeutic' black salve and mouthwash. AB - Black salves are escharotic skin cancer therapies in clinical use since the mid 19th century. Sanguinaria canadensis, a major ingredient of black salve formulations, contains a number of bioactive phytochemicals including the alkaloid sanguinarine. Despite its prolonged history of clinical use, conflicting experimental results have prevented the carcinogenic potential of sanguinarine from being definitively determined. Sanguinarine has a molecular structure similar to known polyaromatic hydrocarbon carcinogens and is a DNA intercalator. Sanguinarine also generates oxidative and endoplasmic reticulum stress resulting in the unfolded protein response and the formation of 8-hydroxyguanine genetic lesions. Sanguinarine has been the subject of contradictory in vitro and in vivo genotoxicity and murine carcinogenesis test results that have delayed its carcinogenic classification. Despite this, epidemiological studies have linked mouthwash that contains sanguinarine with the development of oral leukoplakia. Sanguinarine is also proposed as an aetiological agent in gallbladder carcinoma. This literature review investigates the carcinogenic potential of sanguinarine. Reasons for contradictory genotoxicity and carcinogenesis results are explored, knowledge gaps identified and a strategy for determining the carcinogenic potential of sanguinarine especialy relating to black salve are discussed. As patients continue to apply black salve, especially to skin regions suffering from field cancerization and skin malignancies, an understanding of the genotoxic and carcinogenic potential of sanguinarine is of urgent clinical relevance.

In this article, we discuss the observation that successful instruction following seems to require both the capacity to understand verbal information, but also the ability to transform this information into a procedural format. Here we review the behavioral and neuroimaging literature on following new instructions and discuss how it contributes to our understanding of the functional mechanisms underlying instruction following. Based on this review, we distinguish three phases of instruction following. In the instruction phase, the declarative information of the task instruction is transformed into a task model consisting of a structured representation of the relevant condition-action rules. In the implementation phase, elements of this task model are transformed into a highly accessible state guiding behavior. In the application phase, the relevant condition-action rules are applied. We discuss the boundary conditions and capacity limits of these phases, determine their neural correlates, and relate them to recent models of working memory. PMID- 29173509 TI - Virtuous aging and existential vulnerability. AB - In its efforts to overcome problematic views that associate aging with inevitable decline, contemporary gerontology shows a tendency to focus predominantly on age related vulnerabilities that science may try to remedy and control. However, gerontology should also offer languages to address vulnerabilities that cannot be remedied because they intrinsically belong to the human condition. After all, these are increasingly radically encountered in later life and should therefore be reflected upon in the study of aging. Humanistic gerontology seems to be the most promising field to look for languages capable of contemplating such existential vulnerabilities. The potential contribution of philosophy in this field remains underdeveloped so far, however. This article therefore aims to introduce insights from the philosophical tradition to (humanistic) gerontology. More specifically, it focuses on the tradition of virtue ethics, arguing that virtue is a particularly relevant notion to explore in dealing with existential vulnerability in later life. The notion of virtue is clarified by discussing a selection of philosophical perspectives on this topic, by Aristotle, MacIntyre and Swanton. Next a brief overview will be given of some of the ways the notion of virtue has found its way into gerontological discourse so far. The article ends with an analysis of the merits of virtue-ethical discourse for the study of aging and later life, and pleads for more inclusion of philosophical ideas such as virtue in gerontology, as these can enrich our conceptual frameworks and help us relate to deep existential questions regarding the experience of aging. PMID- 29173510 TI - Understanding functional ability: Perspectives of nurses and older people living in long-term care. AB - The functional ability of older people has come to play a significant role in their care. Policies and public debate promote active aging and the need to maintain functioning in old age, including among older people living in long-term care. This study explores the meanings given to functional ability in the interview talk of long-term care nurses (n=24) and older people living in long term care (n=16). The study is based on discourse analysis and positioning theory. In this study, accounts of functioning differed between nurses and older residents. For the nurses, functional ability was about the basic functions of everyday life, and they often used formal and theoretical language, whereas for older long-term care residents, functional ability was a more versatile concept. Being active was promoted, particularly in the nurses' talk but also sometimes in residents' talk, thereby reflecting the public discourse about functioning. In their talk, the nurses positioned themselves in relation to functional ability as competent professionals and active caregivers. In residents' talk, we found three positions: an active individual taking care of him or herself, a recipient of help, and a burden to nurses. To move in a direction that promotes activity and rehabilitative care, a better understanding of older people's individual needs and their own views of functional ability is needed. PMID- 29173511 TI - Evaluating dementia home care practices: The reification of care norms. AB - This critical ethnographic study examined how power relations shape the nature and enactment of caregivers' evaluation of home-based dementia care practices. As the home care sector continues to evolve and prepare itself as a key element in caring for people living with dementia and their families, this study grounds our understanding of how dementia home care practices are enacted and evaluated, particularly at the interface of formal and familial caregiving. The critical finding from our data is that not all evaluations of care practices were considered equally meaningful or relevant, and, moreover, their significance depended on whether the evaluation was made by someone in a position of power. Renewed awareness of and attention to power relations, such as class and gender, are implicated in the evaluation of care practices. Consequently, challenging how power is enacted in ways that (re)produces and reifies care norms is vital in order to foster equitable and supportive partnerships in home-based dementia care. PMID- 29173512 TI - From home to 'home': Mapping the caregiver journey in the transition from home care into residential care. AB - Family caregivers play a pivotal role in supporting the functional independence and quality of life of older relatives, often taking on a wide variety of care related activities over the course of their caregiving journey. These activities help family members to remain in the community and age-in-place for as long as possible. However, when needs exceed family capacities to provide care, the older family member may need to transition from one care environment to another (e.g., home care to nursing home care), or one level of care to another (from less intense to more intensive services). Drawing upon qualitative interview data collected in a populous health region in British Columbia, Canada, this study explores the roles and responsibilities of family caregivers for family members making the care transition from home care to residential care. A thematic analysis of the interview transcripts resulted in the development of a conceptual framework to characterize the "Caregiver Journey" as a process that could be divided into at least three phases: 1) Precursors to transition - recognizing frailty in family members and caregivers prior to transition; 2) Preparing to transition into residential nursing home care (RC) and 3) Post-transition: Finding a new balance - where caregivers adjust and adapt to new caregiving responsibilities. Our analyses revealed that the second phase is the most complex involving a consideration of the various activities, and roles that family caregivers take on to prepare for the care transition including: information gathering, advocacy and system navigation. We conclude that there is a need for family caregivers to be better supported during care transitions; notably through ongoing and enhanced investments in strategies to support caregiver communication and education. PMID- 29173508 TI - What's in a word? How instructions, suggestions, and social information change pain and emotion. AB - Instructions, suggestions, and other types of social information can have powerful effects on pain and emotion. Prominent examples include observational learning, social influence, placebo, and hypnosis. These different phenomena and their underlying brain mechanisms have been studied in partially separate literatures, which we discuss, compare, and integrate in this review. Converging findings from these literatures suggest that (1) instructions and social information affect brain systems associated with the generation of pain and emotion, and with reinforcement learning, and that (2) these changes are mediated by alterations in prefrontal systems responsible for top-down control and the generation of affective meaning. We argue that changes in expectation and appraisal, a process of assessing personal meaning and implications for wellbeing, are two potential key mediators of the effects of instructions and social information on affective experience. Finally, we propose a tentative model of how prefrontal regions, especially dorsolateral and ventromedial prefrontal cortex may regulate affective processing based on instructions and socially transmitted expectations more broadly. PMID- 29173513 TI - Enabling at-homeness for residents living in a nursing home: Reflected experience of nursing home staff. AB - Older people are often living the last period of their lives in institutions such as nursing homes. Knowledge of this period, specifically related to at-homeness which can be described as wellbeing in spite of illness and has been regarded as one of the goals in palliative care, has been very little researched in the context of nursing homes and the experience of nursing home staff. The aim of this study was to explore the experiences of nursing home staff of how to enable at-homeness for residents. Qualitative interpretive description methodology guided the design. The data generation was conducted in winter 2014-2015, when seven repetitive reflective group discussions with staff in a nursing home were held. The results show five patterns for how healthcare staff enabled at-homeness for the residents: Striving to know the resident, Showing respect for the resident's integrity, Creating and working in family-like relationships, Helping to find a new ordinariness and Preparing and making plans to ensure continuity. Nursing home staff seem to have collegial knowledge of how to enable at-homeness for the residents in a nursing home. Close relationships with respect for the resident's integrity stand out as enabling at-homeness. PMID- 29173514 TI - Is longevity a value for older adults? AB - Longevity is an aspiration at the population level, a goal of public health policy and research. In the later decades of life, longevity goals also deserve scrutiny at the personal level to understand whether people welcome longer lives. Contradictory preferences could be expected, both the embrace of longevity and hesitation. The desire for extended life was examined using qualitative interviews in parallel designs among 90 persons aged 62 and older at sites in Germany, China, and the United States. Just over one third of the participants declined to express aspirations for longer life, some because they felt that their lives had reached a stage of completion and some as a form of fate acceptance. A larger number did indeed want extended lives but less than half estimated an amount of time that they desired. Moreover, there was strong opinion that longer lives were desirable only if current or acceptable levels of health were maintained. These replies indicate that future time is welcome so long as it occurs in the "third age" of independent living and not in the "fourth age" of vulnerability and decline. Replies also reveal that many older adults in these three cultures conceptually map the future not as a smooth continuum of time but rather as segmented into states, one kind of which is wanted and one which is not. PMID- 29173515 TI - Precarity in late life: Understanding new forms of risk and insecurity. AB - Population aging and longevity in the context of declining social commitments, raises concerns about disadvantage and widening inequality in late life. This paper explores the concept of precarity as a means to understand new and sustained forms of risk and insecurity that affect late life. The article begins with a review of the definition and uses of precarity in a range of scholarly fields including social gerontology. It then draws on illustrations from three locations of experience including older women, aging with a disability, and the foreign-born, to outline how precarity renders visible the disadvantages carried into late life, and new insecurities that emerge at the moment of needing care in the context of austerity. The argument being put forward is that precarity can be used to illustrate how risks and insecurities, experienced over time, in longevity, and the context of austerity, can deepen disadvantage. This lens thus holds the potential to challenge individual interpretations of risk, and situate experiences of disadvantage in the economic and political context. We conclude that contemporary conditions of austerity and longevity intersect to produce and sustain risk and disadvantage into late life. PMID- 29173516 TI - Use of Complementary and Alternative Medicine in Inflammatory Bowel Disease Around the World. AB - Use of complementary sand alternative medicine (CAM) is common among patients with inflammatory bowel disease (IBD). CAM can be broadly categorized as whole medical systems, mind-body interventions, biologically based therapies, manipulative and body-based methods, and energy therapies. Most do not use it to treat IBD specifically, and most take it as an adjunct to conventional therapy not in place of it. However, patients are frequently uncomfortable initiating a discussion of CAM with their physicians, which may impact adherence to conventional therapy. A greater emphasis on CAM in medical education may facilitate patient-physician discussions regarding CAM. PMID- 29173518 TI - Dietary Therapies in Pediatric Inflammatory Bowel Disease: An Evolving Inflammatory Bowel Disease Paradigm. AB - Nutrition has long been recognized as a critical component in the treatment of pediatric inflammatory bowel disease (IBD). Formerly, nutritional interventions have focused on targeting improved weight gain and linear growth, as well as correction of micronutrient deficiencies. Recently, there has been growing interest and study of dietary interventions for induction and maintenance of remission. In addition to exclusive enteral nutrition, successes have been achieved with specific exclusion diets. This article evaluates current literature regarding the role of diet and nutrition in pathogenesis of disease, as well as the role of diet as primary therapy for pediatric IBD. PMID- 29173520 TI - Probiotics in Inflammatory Bowel Disease. AB - Evidence indicates that the gut microbiota and/or interactions between the microbiota and the host immune system are involved in the pathogenesis of inflammatory bowel disease (IBD). Strategies that target the microbiota have emerged as potential therapies and, of these, probiotics have gained the greatest attention. Data derived from animal models of IBD have revealed the potential of several bacterial strains to modify the natural history of IBD. However, thought there is some evidence for efficacy in ulcerative colitis and in pouchitis, in particular, there has been little indication that probiotics exert any benefit in Crohn disease. More targeted approaches involving live bacteria, genetically modified bacteria, and bacterial products are now being evaluated. PMID- 29173521 TI - Prebiotics and Inflammatory Bowel Disease. AB - Dietary fiber, specifically prebiotics, is the primary source of energy for the gut microbiota and thus has the potential to beneficially modify microbiota composition. Prebiotics have been used in both in vitro studies and with animal models of colitis with largely positive results. Human studies are few and have been conducted with only a few select prebiotics, primarily fructan-containing fibers. Although disease activity and inflammatory markers have improved, more needs to be learned about the specific prebiotic compounds and how they can be used to best improve the gut microbiota to counter changes induced by inflammatory bowel disease. PMID- 29173519 TI - Diet as a Therapeutic Option for Adult Inflammatory Bowel Disease. AB - There are many mechanisms to explain how food may drive and ameliorate inflammation. Although there are no consistent macronutrient associations inflammatory bowel disease (IBD) development, many exclusion diets have been described: IgG-4 guided exclusion diet; semivegetarian diet; low-fat, fiber limited exclusion diet; Paleolithic diet; Maker's diet; vegan diet; Life without Bread diet; exclusive enteral nutrition (EEN), the Specific Carbohydrate Diet (SCD) and the low FODMAP diet. The literature on diet and IBD is reviewed with a particular focus on EEN, SCD, and low FODMAP diets. Lessons learned from the existing observations and strengths and shortcomings of existing data are presented. PMID- 29173522 TI - Vitamins and Minerals in Inflammatory Bowel Disease. AB - Indiscriminate use of multivitamin/mineral supplements in the general population may be misguided, but patients with chronic Inflammatory Bowel Diseases (IBD) should be monitored and compensated for nutritional deficiencies. Mechanistic links between vitamin/mineral deficiencies and IBD pathology has been found for some micronutrients and normalizing their levels is clinically beneficial. Others, like vitamin A, although instinctively desirable, produced disappointing results. Restoring normal levels of the selected micronutrients requires elevated doses to compensate for defects in absorptive or signaling mechanisms. This article describes some aspects of vitamin and mineral deficiencies in IBD, and summarizes pros and cons of supplementation. PMID- 29173523 TI - Herbs and Inflammatory Bowel Disease. AB - Although herbal preparations are widely used by patients with inflammatory bowel disease (IBD), evidence for their efficacy is limited and they may not always be safe. Mainly small studies of varying quality have suggested that several herbal preparations could be of benefit in IBD, but larger better-designed trials are needed to establish their place in inducing and maintaining remission. Patients and health care workers need to be made more aware of the limitations and risks of using herbal products for IBD. PMID- 29173524 TI - Fecal Transplant in Inflammatory Bowel Disease. AB - Patients with inflammatory bowel disease (IBD) have differences in their gastrointestinal microbiome compared with healthy individuals, although it is unclear whether this is a cause or consequence of chronic inflammation. There is hope that manipulation of the gut microbiome through fecal microbiota transplant (FMT), commonly used to treat patients with Clostridium difficile infection, may also be an effective therapy in IBD. This article reviews the evidence supporting FMT in IBD, including case reports, case series, and randomized controlled trials. The article also focuses on questions of safety and speculates on the future of this therapy. PMID- 29173525 TI - The Brain-Gut Axis and Stress in Inflammatory Bowel Disease. AB - The brain-gut axis serves as a circuit that incorporates the human experience, the state of mind, the gut microbiome, and the immune response that ultimately drives the phenotypic expression of inflammatory bowel disease (IBD). There are several biological pathways through which stress can play a deleterious role, including through increasing intestinal permeability, which can facilitate intestinal translocation of bacteria. Stress has an impact on symptoms in IBD; however, there is limited evidence that stress triggers increased intestinal inflammation. Although attention to stress and psychiatric comorbidity is important in the management of IBD, there are few clinical trials to direct management. PMID- 29173517 TI - Complementary and Alternative Medicine Strategies for Therapeutic Gut Microbiota Modulation in Inflammatory Bowel Disease and their Next-Generation Approaches. AB - The human gut microbiome exerts a major impact on human health and disease, and therapeutic gut microbiota modulation is now a well-advocated strategy in the management of many diseases, including inflammatory bowel disease (IBD). Scientific and clinical evidence in support of complementary and alternative medicine, in targeting intestinal dysbiosis among patients with IBD, or other disorders, has increased dramatically over the past years. Delivery of "artificial" stool replacements for fecal microbiota transplantation (FMT) could provide an effective, safer alternative to that of human donor stool. Nevertheless, optimum timing of FMT administration in IBD remains unexplored, and future investigations are essential. PMID- 29173527 TI - Mindfulness-Based Interventions in Inflammatory Bowel Disease. AB - Mindfulness-based interventions may be beneficial psychosocial treatments for improving the health and well-being of patients with inflammatory bowel disease. This article reviews eight studies, assessing seven psychosocial interventions, which include mindfulness and/or meditation components. Strongest effects of the interventions were found in quality of life and anxiety/depression, with inconsistent or minimal changes in other psychosocial areas, such as perceived stress and in disease-related outcomes and other physiologic functioning. Mindfulness interventions for patients with inflammatory bowel disease may be a supplemental treatment option to improve quality of life and distress in this population, although results are preliminary and interventions require additional testing. PMID- 29173526 TI - Psychological Considerations and Interventions in Inflammatory Bowel Disease Patient Care. AB - The presence of psychological comorbidities, specifically anxiety and depression, is well documented in inflammatory bowel disease (IBD). The drivers of these conditions typically reflect 4 areas of concern: disease impact, treatment concerns, intimacy, and stigma. Various demographic and disease characteristics increase risk for psychological distress. However, the risk for anxiety and depression is consistent throughout IBD course and is independent of disease activity. Early intervention before psychological distress becomes uncontrolled is ideal, but mental health often is unaddressed during patient visits. Understanding available psychological treatments and establishing referral resources is an important part of the evolution of IBD patient care. PMID- 29173528 TI - Massage Acupuncture, Moxibustion, and Other Forms of Complementary and Alternative Medicine in Inflammatory Bowel Disease. AB - Complementary and alternative medicine is frequently used by inflammatory bowel disease (IBD) patients; most common are massage, acupuncture, and moxibustion therapy. Massage therapy is poorly studied in IBD patients; therefore, its benefits remain unknown. Acupuncture and moxibustion therapy have been shown to improve inflammation and symptoms in animal and human studies. However, current clinical trials of acupuncture and moxibustion are of insufficient quality to recommend them as alternative therapy. Nonetheless, because these therapies seem generally to be safe, they may have a role as complementary to conventional therapy. PMID- 29173529 TI - Sleep and Circadian Hygiene and Inflammatory Bowel Disease. AB - There is increasing evidence that sleep and circadian disruption can worsen the disease course in inflammatory bowel disease (IBD). Sleep and circadian disruption are prevalent in society and are associated with worse outcomes in IBD. Emerging research suggests sleep and circadian disruption can impact key components in IBD disease flares, including intestinal permeability, translocation of bacterial endotoxins, intestinal dysbiosis, and proinflammatory cytokines. Much of this research has been conducted in animal models. There is a clear need for large randomized controlled trials in human patients with IBD, where the potential for chronotherapeutic strategies to improve disease course can be tested. PMID- 29173530 TI - Exercise and Inflammatory Bowel Disease: Insights into Etiopathogenesis and Modification of Clinical Course. AB - There is sparse information regarding exercise and inflammatory bowel disease (IBD). Furthermore, the importance of regular exercise in the optimal management of IBD has not received attention in guidelines and is often overlooked by practitioners. This article summarizes evidence regarding health benefits of exercise, guidelines regarding exercise in the general population and chronic inflammatory disorder populations, limitations regarding exercise capacity in patients with IBD, the association of lack of exercise with IBD pathogenesis, the role of exercise in beneficially modulating IBD clinical course, and extraintestinal benefits of exercise in patients with IBD. PMID- 29173531 TI - The Practical Pros and Cons of Complementary and Alternative Medicine in Practice: Integrating Complementary and Alternative Medicine into Clinical Care. AB - Complementary and alternative medicine (CAM) is changing health care for individuals with inflammatory bowel disease. The move toward increasing patient autonomy and addressing lifestyle and psychosocial factors contributes to this shift. Numerous clinics and centers are offering new models to incorporate these elements. There is need for better and more robust data regarding CAM efficacy and safety. CAM offers a test kitchen for new approaches to care and care delivery, which are now being developed and studied, and has the possibility to affect patient quality of life, disease morbidity, cost, and use of health care.

PMID- 29173533 TI - Strongyloides westeri worm and egg counts in naturally infected young horses. AB - Strongyloides westeri is a threadworm parasite found in the small intestine mainly in foals at up to about 4 months of age. This parasite is associated with small intestinal enteritis and diarrhea as well as skin irritation and a clinical syndrome called "frenzied behavior" due to percutaneous invasion. The aim of this study was to investigate S. westeri parasite burdens in age groups older than the initial lactogenic transmission phase. Secondary aims were to examine the impact of host age and gender on worm burden and egg output in naturally infected foals. Thirteen foals were enrolled in the study, exposed to natural infection with S. westeri and were humanely euthanized at ages ranging from 89 to 221days old. Egg counts per gram of feces were determined using the Mini-FLOTAC method. Worms were retrieved from the mucosa of the anterior half of the small intestine using a digestion method and enumerated. The foals were all observed to be healthy with no signs of parasitic disease. Foals at 4-5 months of age had significantly higher S. westeri worm and egg counts compared to those aged 6-8 months (p<0.05). Fecal egg counts were significantly associated with worm counts (p=0.0045). While egg and worm counts declined markedly in the 6-8 month age range, they were not eliminated completely. This could either reflect a new infection acquired orally or transcutaneously, or a subset of adult intestinal parasites acquired via the lactogenic route and surviving for longer time periods. This study provided new information about S. westeri infection patterns in young horses at 4-8 months of age. PMID- 29173534 TI - Canine neutrophils activate effector mechanisms in response to Leishmania infantum. AB - Canine leishmaniosis caused by L. infantum is a severe zoonotic disease. Although macrophages are the definitive host cells, neutrophils are the first cells to encounter the parasite soon after its inoculation in the dermis by the phlebotomine vector. To study the interaction of dog neutrophils and L. infantum promastigotes, blood neutrophils were isolated from healthy donors and the infection was established in vitro. In the majority of the dogs, L. infantum was efficiently phagocytized by neutrophils, and oxidative (superoxide production) and non-oxidative (neutrophil elastase exocytosis) intracellular effector mechanisms were activated, but the release of neutrophil extracellular traps was minimized. Furthermore, promastigotes and culture supernatants induced neutrophil migration, but the prior contact with Leishmania inhibits chemotaxis, which might contribute to neutrophil retention at the inoculation site. Neutrophil-parasite interaction resulted in a decrease in parasite viability, although some intracellular promastigotes survive and maintain their proliferative capacity. These findings indicate that dog neutrophils are competent effector cells able to control the initial L. infantum infection. However, some parasites evade intracellular effector mechanisms and can be transferred to the definitive host cell, the macrophage, contributing to the development of canine leishmaniosis. PMID- 29173535 TI - Ticks circulate Anaplasma, Ehrlichia, Babesia and Theileria parasites in North of Iran. AB - Ticks serve as important vectors of some pathogens of medical importance all over the world and identification of their rate of infection plays an important role for further control of diseases. In the current study, we investigated on ticks collected from north of Iran where raising and caring livestock are the main task of the people in order to find evidences of infection of Babesia, Theileria, Anaplasma and Ehrlichia microbial agents. Totally, 609 hard tick species from two genera Hyalomma and Rhipicephalus including; Hy. scupense, Hy. dromedarii, Hy. rufipes, Hy. marginatum, Hy. asiaticum, Hy. anatolicum, R. bursa, R. sanguineus and R. turanicus were identified. Molecular analysis revealed the presence of Anaplasma, Ehrlichia, Babesia and Theileria microorganism agents in all collected tick species except Hy. asiaticum and R. turanicus. To the best of our knowledge, this is the first report on identification of B. occultans in Hyalomma anatolicum and B. ovis in Hyalomma sp in Iran. PMID- 29173536 TI - Molecular confirmation of Sarcocystis gigantea in a naturally infected sheep in Argentina: A case report. AB - The work describes a case of Sarcocystis gigantea infection in a 3-years-old Corriedale ewe from Buenos Aires Province, Argentina. The ewe was found dead with a poor body condition. Pathological and molecular studies were carried out in order to try and confirm the causative agent of the infection. At necropsy, approx. 100 whitish elliptic (3-5mm to 5-8mm) macrocysts with a hard consistency were observed along the esophageal and pharyngeal muscular layers. Microscopically, the macrocysts consisted of an eosinophilic wall, internal septa originated from the eosinophilic wall and basophilic parasitic cells were located among the septa. The sarcocysts were identified molecularly through PCR amplification and sequencing of a short segment of the 18S rRNA gene. Sequence analysis of the amplified DNA demonstrated 100% identity to S. gigantea sequences previously published. To our knowledge this is the first molecular confirmation of S. gigantea infection in sheep in the Americas. PMID- 29173537 TI - A newly described strain of Eimeria arloingi (strain A) belongs to the phylogenetic group of ruminant-infecting pathogenic species, which replicate in host endothelial cells in vivo. AB - Coccidiosis caused by Eimeria species is an important disease worldwide, particularly in ruminants and poultry. Eimeria infection can result in significant economic losses due to costs associated with treatment and slower growth rates, or even with mortality of heavily infected individuals. In goat production, a growing industry due to increasing demand for caprine products worldwide, coccidiosis is caused by several Eimeria species with E. arloingi and E. ninakohlyakimovae the most pathogenic. The aims of this study were genetic characterization of a newly isolated European E. arloingi strain (A) and determination of phylogenetic relationships with Eimeria species from other ruminants. Therefore, a DNA sequence of E. arloingi strain (A) containing 2290 consensus nucleotides (the majority of 18S rDNA, complete ITS-1 and 5.8S sequences, and the partial ITS-2) was amplified and phylogenetic relationship determined with the most similar sequences available on GenBank. The phylogenetic tree presented a branch constituted by bovine Eimeria species plus E. arloingi, and another one exclusively populated by ovine Eimeria species. Moreover, E. arloingi, E. bovis and E. zuernii, which all replicate in host intestinal endothelial cells of the lacteals, were found within the same cluster. This study gives new insights into the evolutionary phylogenetic relationships of this newly described caprine Eimeria strain and confirmed its close relationship to other highly pathogenic ruminant Eimeria species characterized by macromeront formation in host endothelial cells of the central lymph capillaries of the small intestine. PMID- 29173538 TI - Serological detection of Ascaris suum at fattening pig farms is linked with performance and management indices. AB - The aim of the present study was to determine the association between the presence of Ascaris suum at fattening pig farms, using different serological methods and the percentage of affected livers at slaughter, with performance and management indices. In total, 21 fattening pig farms from the North of Spain were included in the study. Serum samples were collected from pigs at slaughter and analysed for the presence of anti-Ascaris antibodies. For this, two different ELISAs were used. The first was based on the antibody recognition of the A. suum haemoglobin (As-Hb) molecule whereas the second test used the total extract of A. suum lung stage L3. The serological results were subsequently correlated with the percentage of condemned livers at slaughter, management practices and technical performance parameters including average daily gain (ADG) and feed conversion ratio (FCR). According to the data from the slaughterhouse, 12 out of the 21 farms had livers condemned due to liver white spots. A total of 10 farms (48%) had an average optical density ratio (ODr) exceeding the test cutoff when the As Hb ELISA was used. This number increased to 18 farms (81%) when using the As-Lung L3 ELISA. The average ODr of the farms on both ELISAs correlated positively with the percentage of affected livers (P<0.01). Only the average ODr values obtained with the As-Lung-L3 ELISA were positively correlated with the FCR (P<0.01). No correlation was found between percentage of affected livers or serology and the ADG. In relation to management practices, farms with greater than or equal to 50% slatted flooring and that applied the 'all-in/all-out' flow system showed a lower percentage of liver condemnations (P<0.01), lower average ODr results on the As Lung-L3 ELISA (P<0.05) and lower FCR (P<0.01) compared with those with less than 50% slatted flooring. This study emphasizes that serology is a promising diagnostic tool for diagnosing ascariasis at fattening pig farms. It also supports earlier findings that the presence of A. suum can have a significant negative impact on farm productivity and that stable infrastructure or management practices can have a considerable impact on the control of this parasite. PMID- 29173539 TI - Leishmania infantum-specific IFN-gamma production in stimulated blood from dogs with clinical leishmaniosis at diagnosis and during treatment. AB - There is limited data regarding Leishmania infantum specific T cell mediated immunity in naturally infected sick dogs at the time of diagnosis and during anti Leishmania treatment. Our aim was to investigate the kinetics of L. infantum specific IFN-gamma production in dogs with leishmaniosis at the time of diagnosis and during treatment and to correlate it with specific L. infantum antibodies, blood parasitemia and clinicopathological findings. Thirty-four dogs were diagnosed with leishmaniosis based on physical examination, routine laboratory tests and L. infantum-specific antibody levels by quantitative ELISA. Heparinized whole blood was stimulated with L. infantum soluble antigen (LSA) and concanavalin A (ConA) and incubated for 5days. IFN-gamma concentration was evaluated in supernatants of stimulated blood using a commercial sandwich ELISA. Leishmania real-time PCR was also performed for assessing blood parasitemia. Dogs were treated with meglumine antimoniate and allopurinol. Sixteen dogs were classified as IFN-gamma non-producers after LSA stimulation (mean+/-SD: 0+/ 0pg/mL) and 18 dogs as IFN-gamma producers (mean+/-SD: 2885.3+/-4436.1pg/mL) at the time of diagnosis (P<0.0001). IFN-gamma non-producers were classified in a more severe clinical staging than IFN-gamma producers that presented a mild to moderate clinical staging (P=0.03). In the IFN-gamma non-producer group, production of IFN-gamma after LSA stimulation was significantly increased during treatment especially at day 365 (P=0.018) together with clinical improvement when compared with day 0. In contrast, IFN-gamma producers maintained their IFN-gamma production after LSA stimulation and no statistically significant changes were found during treatment follow-up. At diagnosis, IFN-gamma non-producers showed a significantly higher blood parasitemia versus IFN-gamma -producers (P=0.005). IFN gamma non-producers drastically reduced blood parasitemia to minimum values at day 365 when compared with day 0 (P=0.017). No significant differences were found at day 365 in blood parasitemia of IFN-gamma producers compared to pre-treatment. At diagnosis, L. infantum specific antibodies were higher in IFN-gamma non producers than IFN-gamma producers (P=0.014). A marked reduction of antibody levels was found at day 365 when compared with day 0 in IFN-gamma non-producers (P=0.005) and producers (P=0.001). These results demonstrate that IFN-gamma concentration increases with long-term anti-Leishmania treatment together with clinical improvement in dogs that do not produce IFN-gamma at diagnosis. Together with clinical recovery, reduction in blood parasitemia and L. infantum specific antibodies, tracking IFN-gamma concentration could constitute an important prognostic tool for immune monitoring in CanL.

AB - Information on the susceptibility status of Fasciola hepatica isolates is lacking in the literature, even for those isolates considered to be laboratory reference strains. Four controlled efficacy studies were conducted on two Fasciola hepatica isolates from Australia, viz. 'Oberon' and 'Sunny Corner' with treatment at either 2, 6 or 10 weeks post-infection (wpi) as defined in each study. Fluke burdens and examination of livers occurred at necropsy in weeks 12 (Study 1) or 13 (Studies 2, 3 and 4) post-infection. The triclabendazole (TCBZ) resistance status of the Oberon isolate was confirmed in 6 and 10-week old F. hepatica, utilizing the drug alone (Fasinex; 71.5% and 31.1%, respectively) and in combination with oxfendazole (Flukazole C; 79.9% and 0%, respectively). The susceptibility of this isolate to albendazole, as well as salicylanilide and sulphonamide drugs was confirmed. The Sunny Corner isolate was confirmed as susceptible to TCBZ (>99% all stages) and closantel (>90% at >=6 wpi).

AB - We evaluated the direct effects of progesterone on the morphology, maturation and behavior of Haemonchus contortus larvae in vitro. The presence and location of possible progesterone receptors in these larvae were also determined. The addition of 8ng/mL of progesterone to larval cultures over 10days reduced larval enlargement, while the addition of 160ng/mL of the hormone increased the enlargement. Up to 62% and 65% of the H. contortus larvae molted from third-stage larvae (L3) to fourth-stage larvae (L4) when cultured in RPMI-1640 media without hormone for 5 and 10days, respectively. The addition of different progesterone concentrations (1, 8, 16, 80 and 160ng/mL) to the larval cultures significantly inhibited the molting process within the same periods. The addition of 8ng/mL or higher progesterone concentrations to the cultures significantly increased larval motility (p<0.05) compared with unstimulated larvae. Flow cytometry showed the expression of progesterone receptors (P4-R) in 15% of the cells from newly isolated H. contortus larvae. When the larvae were cultured for 5days in the presence of the hormone, the percentage of P4-R+ cells remained the same. In contrast, unstimulated larvae showed a significant reduction in the number of P4 R+ cells. Using confocal microscopy, a greater concentration of P4-Rs was immunolocated in the anterior portion of the alimentary tract of the larvae, suggesting that the cells in this region are targeted by the hormone. The results of the present study show that H. contortus larvae have possible P4-Rs and respond to this hormone by inhibiting their molting process, thereby suggesting the participation of progesterone in the larval arrest phenomenon. PMID- 29173542 TI - Regression models to assess the risk factors of canine gastrointestinal parasitism. AB - Gastrointestinal parasites, protozoa and helminths, remain a common important finding in dogs presented to veterinary medical practices. Moreover, dogs may play an active role in the transmission of enteric parasites to humans, given their cohabitation, making canine gastrointestinal parasitism an issue of major concern for public health. To get an overview of the current state of canine gastrointestinal parasites' prevalence in Greece, a total of 1036 faecal samples were collected from dogs either presented in veterinary clinics or in animal shelters. Samples were examined by a combined sedimentation-flotation technique. Possible risk factors (age, ownership status, co-existence with other animals, coinfection with other parasites) were assessed using binary regression models for each one of the most prevalent parasites. The overall gastrointestinal parasite prevalence in dogs' faecal samples was 39%. A total of 11 intestinal parasitic species were detected and up to five different parasites were isolated in the same faecal sample. Toxocara canis was the most prevalent parasite in the studied population, followed by Isospora spp., Giardia spp., Uncinaria spp., Trichuris vulpis, Ancylostoma spp., Toxascaris leonina, and Dipylidium caninum. Additionally, other genera (Taenia, Capillaria and Angiostrongylus) were also detected in very low percentages. Young, stray, living without other dogs, coinfected with T. vulpis or T. canis and free of Isospora spp. dogs were more likely to be infected by Giardia spp. Likewise, young, stray, coinfected with T. vulpis or T. canis but free of Giardia spp. dogs were more likely to be infected by Isospora spp. T. canis infections were more common in dogs coinfected with Isospora spp., Giardia spp., D. caninum, Tauaenia spp., T. vulpis and T. leonina Finally, T. vulpis more often infected older dogs and dogs coinfected with Isospora spp., Giardia spp. and T. canis Consequently, the prevalence of parasitized dogs was high and the diversity of parasites found was notable, which calls for a greater awareness among veterinarians and pet owners. The proposed prediction models should be taken under consideration in diagnostic approach of clinical cases, as well as in planning sustainable antiparasitic strategies. PMID- 29173543 TI - Canine visceral leishmaniasis follow-up: a new anti-IgG serological test more sensitive than ITS-1 conventional PCR. AB - Visceral leishmaniasis (VL) is a neglected tropical disease with dogs serving as reservoirs for one of its etiological agents, Leishmania infantum. In Brazil, VL control involves culling of seropositive dogs, among other actions. However, the most employed serological tests lack accuracy, and are not able to detect canine visceral leishmaniasis (CVL) during the early stages of infection. Early detection of CVL is highly desirable in order to shorten the contact time between the infected reservoirs and the vectors. In this study, we investigated the ability of two multiepitope proteins, PQ10 and PQ20, to detect CVL at earlier stages than currently employed methods, including ITS-1 conventional PCR. Using serum samples from naturally infected dogs, we observed that ELISA-PQ10 and ELISA PQ20 were able to detect Leishmania infection at earlier time points as compared with kDNA PCR-RFLP in anti-IgG and anti-IgM assays. Using sera from experimentally infected dogs, we monitored seroconversion using multiepitope proteins, ELISA-crude antigen, as well as ITS-1 conventional and real-time PCR. While seroconversion was detected by ELISA-crude antigen in 16.6% of the dogs, multiepitope proteins were able to detect seroconversion in more than 80% of them. Moreover, the ability of ELISA-PQ10 and ELISA-PQ20 to detect Leishmania infection at earlier time points as compared with conventional PCR was also confirmed in experimental infection dogs' sera. Immunofluorescence to Babesia canis and Ehrlichia canis did not show cross-reactions with ELISA-PQ10/PQ20 positive samples. Results of real-time PCR and ELISA with multiepitope proteins were very similar, with concordances between 80 and 100%. Furthermore, our findings indicated that PQ10 and PQ20 immunoassays can be related to parasite load. ELISA-PQ10 and ELISA-PQ20 are more sensitive diagnostic tools for early CVL detection as compared with other methods They could potentially be used in screening tests due to easy execution and low costs facilities. PMID- 29173544 TI - Zoonotic and host-adapted genotypes of Cryptosporidium spp., Giardia duodenalis and Enterocytozoon bieneusi in dairy cattle in Hebei and Tianjin, China. AB - A total of 1040 fecal samples, collected from 12 dairy cattle farms in Hebei and Tianjin, near the Bohai area of China, were screened for Cryptosporidium spp., Giardia duodenalis and Enterocytozoon bieneusi by polymerase chain reaction. The overall prevalence for Cryptosporidium, G. duodenalis and E. bieneusi was 1.0% (n=10), 4.7% (n=49) and 19.4% (n=202), respectively. Ten Cryptosporidium-positive samples were identified as C. parvum by DNA sequence analysis of the small subunit rRNA (SSU rRNA) gene. DNA sequencing of the 60-kDa glycoprotein gene revealed that the C. parvum samples were all subtype IIdA19G1. Forty-nine G. duodenalis-positive samples belonged to assemblage E (n=47) and assemblage E mixed with A (n=2), based on the sequenced SSU rRNA, triosephosphate isomerase, and glutamate dehydrogenase genes. Sequence analysis of the internal transcribed spacer (ITS) gene identified six known E. bieneusi genotypes, I (n=87), J (n=83), BEB4 (n=18), BEB6 (n=3), N (n=1) and Ebpc (n=1), along with three new genotypes, CHC6 (n=1), CHC7 (n=1) and CHC8 (n=7). Phylogenetic analysis showed that Ebpc belonged to zoonotic group 1, whereas the other E. bieneusi genotypes clustered within group 2. More studies are needed to better understand the species distributions and public health significance of these pathogens in the study areas. PMID- 29173545 TI - Anthelminthic activity of methanol extracts of Diospyros anisandra and Petiveria alliacea on cyathostomin (Nematoda: Cyathostominae) larval development and egg hatching. AB - Methanol extracts of plant structures are promising alternatives to traditional pharmaceutical anthelminthic treatments. An in vitro evaluation was done of how methanol extracts of Diospyros anisandra bark and leaves, and Petiveria alliacea stems and leaves, collected during the rainy and dry seasons, effected cyathostomin larval development and egg hatching. Seven concentrations (600, 300, 150, 75, 37.5, 18.7 and 9.3MUg/ml) were tested using the egg hatch assay. An ANOVA was applied to identify differences between the concentrations and the controls. Fifty percent lethal concentration (LC50) and the 95% confidence interval were calculated with a probit analysis. At and above 37.5MUg/ml, the D. anisandra bark extracts from both seasons exhibited >=95% egg hatch inhibition (EHI), while the D. anisandra leaf extracts had >90% EHI at and above 75MUg/ml. For P. alliacea, the extracts from leaves and stems from either season exhibited >97% EHI at and above 300MUg/ml, although similar efficacy was also observed at lower concentrations with the rainy season stems (75MUg/ml) and leaves (150MUg/ml). Values for LC50 were lowest for the rainy season D. anisandra bark (10.2MUg/ml) and leaf extracts (18.4MUg/ml), followed by the rainy season P. alliacea stems extract (28.2MUg/ml). In the D. anisandra extracts, EHI was largely due to its ovicidal activity (>=96% beginning at 37.5MUg/ml), whereas in the P. alliacea extracts it was due to L1 larval hatch failure (>=90% beginning at 75MUg/ml). Overall, the rainy season D. anisandra bark extracts had a strong in vitro anthelminthic effect against cyathostomins by inhibiting larval development, and the rainy season P. alliacea stem extracts had a strong effect by preventing egg hatching. Both are possible control alternatives for these nematodes. PMID- 29173546 TI - Season-long control of flea and tick infestations in a population of cats in the Aeolian archipelago using a collar containing 10% imidacloprid and 4.5% flumethrin. AB - Cats that have outdoor access are highly exposed to ticks, fleas, mites and flying insects, though the risk to become infested by arthropods is less perceived in cats than in dogs. This has resulted in fewer treatment and prevention options being available for cats than for dogs. A collar containing a combination of 10% imidacloprid and 4.5% flumethrin (Seresto(r), Bayer Animal Health) is available for cats and licensed with claims against ticks and fleas for 7-8 months. Following the assessment of the efficacy of the collar against Leishmania infantum infection in privately owned cats living in the Aeolian archipelago, herein we report the efficacy of the collar in the treatment and prevention of tick and flea infestations in the same population of cats over a period of one year of observation. At the inclusion day (Study Day 0, SD 0), cats were visited and examined for ectoparasites (i.e., flea combing and tick thumb counts) and allocated to group 1 (G1; n=104; cats treated with Seresto(r) collar) or group 2 (G2; n=100; untreated controls) and further checked at SDs 210, 270 and 360 (study closure). At SD 0, G1 and G2 had a comparable percentage of cats infested by fleas (45.2% and 49.0%; chi2=0.164; P=0.6859) and ticks (6.7% and 14.0%; chi2=2.946; P=0.0861). The number of cats infested by fleas was reduced in G1, being 8.3%, 0% and 3.8% on SDs 210, 270 and 360, respectively, resulting in efficacies against fleas of 79.4%, 100% and 93.6% on SDs 210, 270 and 360. None of the cats in G1 was found infested by ticks after the application of the collar, whereas in G2 ticks were observed on 15.7%, 4.8%, 17.5% of the cats at the different follow up visits, leading to an overall efficacy against ticks of 100%. A total of 375 ectoparasites were collected from cats, being 249 fleas (six Ctenocephalides canis, 240 Ctenocephalides felis and three Nosopsyllus fasciatus) and 126 ticks (87 Ixodes ventalloi and 39 Rhipicephalus pusillus). Field data gathered herein confirm a high efficacy of the collar in the prevention of tick and flea infestations on cats. This is of great importance both for the primary role of fleas and ticks as blood feeding parasites and, more importantly, because of their role as vectors of pathogens causing diseases of veterinary and medical importance. PMID- 29173547 TI - Bobcats (Lynx rufus) are natural definitive host of Besnoitia darlingi. AB - Bovine besnoitiosis, caused by Besnoitia besnoiti, is an economically important disease of cattle in many countries but its transmission remains a mystery. Wild felids are suspected to be its definitive hosts. The domestic cat (Felis catus) is known experimental definitive host for Besnoitia species of rodents. Here, we report for Besnoitia darlingi the first identification of a natural definitive host, the bobcat (Lynx rufus). Oocysts resembling Toxoplasma gondii (unsporulated; 10.9+/-0.8*12.1+/-0.2MUm; n=5) were detected microscopically in the feces of two of 25 free ranging wild bobcats from Mississippi, USA. After detailed investigation, we identified these oocysts as B. darlingi and not T. gondii. The IFN-gamma gene knockout (KO) mice fed oocysts from bobcats died of acute besnoitiosis and tachyzoites were found in their tissues. Oocysts were also mildly pathogenic to outbred Swiss Webster mice (SW) (Mus musculus). The SW mice fed oocysts became ill but generally survived and developed characteristic thick walled Besnoitia tissue cysts in their tongue and heart muscles and brains. Two laboratory-raised domestic cats (Felis catus) excreted B. darlingi oocysts after ingesting murine tissues infected with bobcat-derived oocysts. The parasite was successfully cultivated in African green monkey kidney fibroblast cells (CV-1 cell line) seeded with infected murine tissue homogenate. The multilocus PCR-DNA sequencing (18S rDNA, 28S rDNA, and ITS-1) from culture-derived tachyzoites confirmed the parasite as B. darlingi. Our results suggest that bobcats may be an important link in the sylvatic cycle of Besnoitia species and bioassay or molecular tests are needed to differentiate Toxoplasma gondii-like oocysts in feces of felids, both domestic and wild cats. PMID- 29173548 TI - Haemonchus contortus beta-tubulin isotype 1 gene F200Y and F167Y SNPs are both selected by ivermectin and oxfendazole treatments with differing impacts on anthelmintic resistance. AB - Parasitism by Haemonchus contortus is one of the main limiting factors in small ruminant production in tropical areas. Benzimidazoles (BZ) and macrocyclic lactones (ML) are the most used anthelmintic classes in gastrointestinal nematodes control. There is considerable scientific evidence of a possible relation between the anthelmintic resistance to BZ and ML. This study aimed to characterize the dynamics of anthelmintic resistance in an H. contortus susceptible isolate under selection pressure for BZ and ML alone or in combination and the role of isotype 1 beta-tubulin gene SNPs in these situations. A total of 12 Somali sheep were infected with 5000 third stage larvae of H. contortus Inbred-Susceptible Edinburgh (ISE) isolate. Once infection was established, animals were distributed in three groups (n=4), each treated with crescent doses of oxfendazole (OXF), ivermectin (IVM) and oxfendazole plus ivermectin (IVMOXF). An additional control group with untreated animals was maintained during the entire experiment. After each treatment, eggs were collected and real-time PCR was performed to identify single nucleotide polymorphisms (SNPs) F167Y, F200Y and E198A, in addition to egg hatch test (EHT) for BZ and larval development test (LDT) for ivermectin resistance. All treatments led to increased resistance allelic frequencies at SNPs F200Y and F167Y (p <0.05). In vitro results showed increased phenotypic resistance against both anthelmintic classes in groups IVM and IVMOXF while group OXF only developed resistance against BZ. Finally, we provide evidence that while isotype 1 beta tubulin gene SNPs may have some involvement with ML resistance, the presence of these beta-tubulin SNPs alone are not sufficient to develop ML resistance. PMID- 29173549 TI - A Layered Anatomic Description of the Anterolateral Complex of the Knee. AB - Variability in anatomic terminology, dissection protocols, and use of embalmed as opposed to fresh frozen specimens has led to the controversy surrounding the "anterolateral ligament of the knee." Conceptually the complex anatomy of the anterolateral knee is made up of the superficial, middle, deep, and capsulo osseous layers of the iliotibial band. The anterolateral capsule is deep to these tissues and is directly attached to the lateral meniscus. These structures collectively form the anterolateral complex of the knee. The anterolateral complex in conjunction with the anterior cruciate ligament function to prevent anterolateral rotatory instability of the knee. PMID- 29173550 TI - The Role of an Extra-Articular Tenodesis in Revision of Anterior Cruciate Ligament Reconstruction. AB - Patients who present for anterior cruciate ligament (ACL) revision with a high grade pivot shift at the time of an index ACL revision procedure and subsequent reconstruction failure or a high-grade pivot shift at revision surgery, patients with generalized joint laxity, and those requiring softs tissue grafts should be considered candidates for lateral tenodesis to supplement intraarticular graft revision. Although there is no consensus regarding the optimal lateral tenodesis technique, due to the tibial positioning associated with tensioning and fixation of extra-articular procedures, a lateral tenodesis should not be used in patients with posterolateral corner injuries or lateral compartment articular disease. PMID- 29173551 TI - Extra-Articular Plasty for Revision Anterior Cruciate Ligament Reconstruction. AB - Recent studies have renewed interest in the structures of the anterolateral aspect of the knee. Concomitant damage to these structures in the setting of anterior cruciate ligament rupture has led to various surgical techniques to address these combined injuries. This article is a description of the rationale and the indications for lateral extra-articular tenodesis as well as surgical technique. PMID- 29173552 TI - The Influence of Tibial and Femoral Bone Morphology on Knee Kinematics in the Anterior Cruciate Ligament Injured Knee. AB - Bone morphology is one feature that contributes to knee kinematics. The geometry of the tibia and femur vary across individuals, and these differences can influence the risk of anterior cruciate ligament (ACL) injury and of failure after isolated ACL reconstruction. There has been renewed interest in lateral extra-articular stabilization procedures to supplement an ACL reconstruction, although which patients benefit most from these procedures remains unclear. This article reviews the impact of bone morphology on knee kinematics, including tibial slope, depth of the medial tibial plateau, intercondylar notch shape, tibial eminence volume, and sphericity of the femoral condyles. PMID- 29173553 TI - What Is the State of the Evidence in Anterolateral Ligament Research? AB - The anterolateral ligament (ALL) is a capsular structure of the knee that is the subject of increasing academic interest. This article reviewed recent ALL literature in terms of subject matter and quality. Although current literature focusing on the ALL is small and limited to level 4 and 5 evidence, it is rapidly expanding. Cadaveric studies describing ALL biomechanics are the most common study design, followed by radiographic studies. The methodologic quality of cadaveric studies focusing on the ALL is high. Clinically oriented research pertaining to the diagnosis, therapy, prevalence, or prognosis of injury to the ALL is presently lacking.

PMID- 29173555 TI - Biomechanical Proof for the Existence of the Anterolateral Ligament. AB - With the recent "description" of the anterolateral ligament (ALL) of the knee, its role in controlling rotational stability has reemerged. An improved understanding of the anatomy of the anterolateral complex of the knee has led to an expansion of the literature on the biomechanics of many structures, including the contribution of the iliotibial band and its deep (Kaplan) fibers, the capsulo osseous layer, the ALL, and the lateral meniscal posterior root to knee stability. This article describes the primary and secondary roles of key anatomic structures at the anterolateral aspect of the knee. PMID- 29173556 TI - Structural Properties of the Anterolateral Complex and Their Clinical Implications. AB - The role of the anterolateral complex of the knee in providing static and rotatory knee stability has been a source of renewed interest in the literature. Several studies have established a role of the anterolateral complex in controlling knee rotational stability. Although the objective quantification of knee kinematics and stability has been investigated, understanding of the structural properties of the anterolateral complex is evolving. This article highlights recent evidence pertaining to the structural properties of the anterolateral structures. The biomechanical evaluation of the structural properties of the anterolateral complex of the knee yielded minimal involvement in controlling knee rotational stability. PMID- 29173557 TI - Secondary Stabilizers of Tibial Rotation in the Intact and Anterior Cruciate Ligament Deficient Knee. AB - The controversy regarding the existence and function of the anterolateral ligament or anterolateral complex has reinvigorated interest in rotational stability of the knee joint. This is particularly true of anterolateral rotary instability, as many patients, despite anatomic reconstruction of their anterior cruciate ligament, continue to experience instability. Many experts point toward compromised anterolateral restraints as the underlying culprit, namely, the anterolateral complex, which includes the iliotibial band, anterolateral capsule, lateral meniscus, and lateral collateral ligament. This article provides a breakdown of these structures, their function, biomechanical properties, and clinical importance, based on a thorough review of available literature. PMID- 29173558 TI - Do We Need Extra-Articular Reconstructive Surgery? AB - With renewed interest in the lateral soft tissue envelope anatomy, there is also a rise in the popularity of extra-articular anterolateral procedures. There is reasonable laboratory-based evidence for additional benefit of such procedures, but clinical data are not sufficient to judge outcome in the long term for better or worse. Furthermore, the decision-making process to decide when to add an extra articular procedure is lacking; there are no clinical tests or investigations to guide the clinician. This article presents an overview of the literature and reflections from the authors on the subject. PMID- 29173559 TI - Anterolateral Ligament Reconstruction or Extra-Articular Tenodesis: Why and When? AB - Residual rotational laxity following anterior cruciate ligament (ACL) reconstruction has been identified as significant concern in many patients, despite evolution of techniques. The expanding body of knowledge on the anatomy and biomechanics of the anterolateral soft tissue restraints in rotational control of the knee has reignited an interest in extra-articular reconstruction techniques for augmenting ACL reconstruction. Reconstruction techniques currently used can be broadly categorized as either lateral extra-articular tenodesis or reconstruction of the anterolateral ligament. In this article, we outline the relevant anatomy, biomechanics, and rationale behind the indications and technique of our current extra-articular augmentation procedure. PMID- 29173560 TI - Extra-Articular Tenodesis in Combination with Anterior Cruciate Ligament Reconstruction: An Overview. AB - Anterior cruciate ligament (ACL) reconstruction is a successful procedure with high rates of return to sport. However, some patients experience persistent instability and graft failure. These adverse events have a significant impact, especially on high-level athletes. In an effort to improve outcomes for these patients, more attention is being paid to the anatomic structures at the anterolateral aspect of the knee. The anterolateral structures of the knee have been shown to play a major role in decreasing rotatory knee instability and forces across the ACL graft following reconstruction. This article discusses the indications and techniques for anterolateral ligament reconstruction or lateral extra-articular tenodesis, along with the newest anatomic and biomechanics concepts.

AB - PURPOSE: To estimate changes in preterm delivery (PTD) in the United States from 2006 to 2012 by clinical circumstance, timing of delivery, and race/ethnicity. METHODS: We used vital statistics natality data on all singleton live births from the 18 U.S. states continuously using the 2003 birth certificate from 2006 to 2012. We estimated change in PTD overall and by clinical circumstance (spontaneous vs. medically indicated) and delivery timing among all women and by race/ethnicity, using descriptive and multivariable regression methods. RESULTS: Overall, indicated, and spontaneous PTD declined by 10.31%, 8.40%, and 11.52%, respectively. Late-preterm, early-term, and post-term deliveries decreased substantially (12.13%, 18.37%, and 32.20%, respectively), with simultaneous increase (13.57%) in full-term deliveries. Non-Hispanic white, non-Hispanic black, and Asian/Pacific Islander women experienced larger declines in PTD compared with Hispanic and American Indian/Alaska Native women. Non-Hispanic white women experienced larger declines in late and medically indicated PTD, while non-Hispanic black women experienced larger declines in early and moderate and spontaneous PTD. CONCLUSIONS: Overall, spontaneous, and indicated PTD declined from 2006 to 2012. Declines were lower than previously reported and differed substantially by race/ethnicity.

AB - PURPOSE: The purpose of the article was to examine the relationship between body mass index (BMI) trajectories during infancy and risk of obesity at the age of 6 years. METHODS: We used data on 1169 children with at least two BMI measures during their first year of life from the Infant Feeding Practices Survey II and its Year 6 Follow-Up. Latent class growth analysis was used to identify distinct trajectories of BMI, and multiple logistic regression analyses were used to assess the association of the identified trajectories with obesity at the age of 6 years. RESULTS: Three trajectories of BMI were identified during the first year of life: low stable (80.2%), high stable (16.9%), and rising (2.8%). Obesity at the age of 6 years was highest among children with a high-stable trajectory (17.2%), followed by the low-stable (9.6%) and rising (9.1%) groups. Compared with those in the low-stable trajectory, the adjusted odds ratio for obesity at the age of 6 years was 1.79 (95% confidence interval 1.13-2.84) in children with the high-stable growth trajectory and 0.84 (0.26-2.72) in children with the rising growth trajectory. CONCLUSIONS: High-stable BMI trajectory in infancy resulted in a higher risk for obesity at the age of 6 years, but had low accuracy for identifying obese children at the age of 6 years. PMID- 29173578 TI - Examining racial disparities in colon cancer clinical delay in the Colon Cancer Patterns of Care in Chicago study. AB - PURPOSE: We explored a potential racial disparity in clinical delay among non Hispanic (nH) Black and White colon cancer patients and examined factors that might account for the observed disparity. METHODS: Patients aged 30-79 years with a newly diagnosed colon cancer from 2010 to 2014 (n = 386) were recruited from a diverse sample of nine public, private, and academic hospitals in and around Chicago. Prolonged clinical delay was defined as 60 days or more or 90 days or more between medical presentation (symptoms or a screen-detected lesion) and treatment initiation (surgery or chemotherapy). Multivariable logistic regression with model-based standardization was used to estimate the disparity as a difference in prevalence of prolonged delay by race. RESULTS: Prevalence of delay in excess of 60 days was 12 percentage points (95% confidence interval: 2%, 22%) higher among nH Blacks versus Whites after adjusting for age, facility, and county of residence. Travel burden (time and distance traveled from residence to facility) explained roughly one-third of the disparity (33%, P = .05), individual and area-level socioeconomic status measures explained roughly one-half (51%, P = .21), and socioeconomic measures together with travel burden explained roughly four-fifths (79%, P = .08). CONCLUSIONS: Low socioeconomic status and increased travel burden are barriers to care disproportionately experienced by nH Black colon cancer patients. PMID- 29173579 TI - Contextual effects and cancer outcomes in the United States: a systematic review of characteristics in multilevel analyses. AB - PURPOSE: There is increasing call for the utilization of multilevel modeling to explore the relationship between place-based contextual effects and cancer outcomes in the United States. To gain a better understanding of how contextual factors are being considered, we performed a systematic review. METHODS: We reviewed studies published between January 1, 2002 and December 31, 2016 and assessed the following attributes: (1) contextual considerations such as geographic scale and contextual factors used; (2) methods used to quantify contextual factors; and (3) cancer type and outcomes. We searched PubMed, Scopus, and Web of Science and initially identified 1060 studies. One hundred twenty-two studies remained after exclusions. RESULTS: Most studies utilized a two-level structure; census tracts were the most commonly used geographic scale. Socioeconomic factors, health care access, racial/ethnic factors, and rural-urban status were the most common contextual factors addressed in multilevel models. Breast and colorectal cancers were the most common cancer types, and screening and staging were the most common outcomes assessed in these studies. CONCLUSIONS: Opportunities for future research include deriving contextual factors using more rigorous approaches, considering cross-classified structures and cross-level interactions, and using multilevel modeling to explore understudied cancers and outcomes. PMID- 29173580 TI - Building the pipeline: programs to introduce middle school, high school, medical, and veterinary students to careers in epidemiology and public health. AB - PURPOSE: This report describes Centers for Disease Control and Prevention programs that expose students to epidemiology and public health sciences (EPHS). METHODS: The Science Ambassador workshop targets middle and high school teachers and promotes teaching EPHS in the classroom. The National Science Olympiad Disease Detectives event is an extracurricular science competition for middle and high school students based on investigations of outbreaks and other public health problems. The Epidemiology Elective Program provides experiential learning activities for veterinary and medical students. RESULTS: As of 2016, 234 teachers from 37 states and territories and three other countries participated in SA workshops. Several are teaching units or entire courses in EPHS. The National Science Olympiad Disease Detectives event exposed approximately 15,000 middle and high school students to EPHS during the 2015-2016 school year. The Epidemiology Elective Program has exposed 1,795 veterinary and medical students to EPHS. CONCLUSIONS: Students can master fundamental concepts of EPHS as early as middle school and educators are finding ways to introduce this material into their classrooms. Programs to introduce veterinary and medical students to EPHS can help fill the gap in exposing older students to the field. Professional organizations can assist by making their members aware of these programs. PMID- 29173581 TI - SUB-GROUPS? BEAR WITH ME! PMID- 29173582 TI - Staphylococcus agnetis, a potential pathogen in broiler breeders. AB - In this study, four broiler parent flocks have been followed from the onset of the production period (week 20) until slaughter (week 60). Every week, approximately ten dead broiler breeders, randomly selected among birds dead on their own, were collected and subjected to a full post mortem analysis including bacteriological examination. In total 997 breeders were investigated and for the first time Staphylococcus agnetis was isolated in pure culture from cases of endocarditis and septicemia from 16 broiler breeders. In addition, the cloacal flora from newly hatched chickens originating from the same four flocks were characterized and S. agnetis was found in pure culture of several newly hatched chickens (n=12) and only in one case in combination with another species. Clonality of the isolates was examined by pulsed-field-gel-electrophoresis which showed indistinguishable patterns in isolates from both broiler breeders and broilers. Three isolates were whole genome sequenced to obtain knowledge on virulence genes. The isolates harbored a number of genes encoding different fibrinogen binding proteins and toxins which might be important for virulence. The present findings demonstrate that S. agnetis may be associated with mortality in broiler breeders. No disease was associated with the broilers which were found positive for S. agnetis in the cloaca. PMID- 29173583 TI - Pathogenicity and transmissibility of a highly pathogenic avian influenza virus H5N6 isolated from a domestic goose in Southern China. AB - Since the first outbreak of H5N6 reported in Laos at 2013, there has been a dramatic increase in H5N6 strains isolated from waterfowl in China, particularly Southern China. However, pathogenicity and transmissibility of the virus in different birds remain largely unknown. In this study, a novel H5N6 virus, termed QY01, that belonged to group C in 2.3.4.4 was isolated from an apparently healthy domestic goose in Guangdong province, southern China in 2016. In order to simulate the natural transmission of different kinds of birds, we evaluated its pathogenicity and transmissibility in chickens, domestic geese and pigeons. To investigate the replication and shedding of QY01 in poultry, chickens, geese and pigeons were inoculated intranasally with 106 EID50 of virus. In addition, to measure intra-species transmission of QY01, three sentinel birds were housed with each group. The results demonstrated that QY01 exhibited a highly pathogenic phenotype, and was transmissible among in chickens and geese. However, the virus did not appear to be pathogenic in pigeons, indicating that this novel H5N6 virus exhibited different host ranges and tissue tropisms, and may pose a substantial risk for the chicken and goose industry. Therefore, continued surveillance for H5N6 AIVs is necessary, and increased attention should be paid to cross-species transmission between waterfowl and terrestrial birds. PMID- 29173584 TI - Candida parapsilosis complex in veterinary practice: A historical overview, biology, virulence attributes and antifungal susceptibility traits. AB - The Candida genus is composed by yeast that commensally live as part of human and animal microbiota. In the last years, C. parapsilosis complex, composed by the cryptic species C. parapsilosis sensu stricto, C. orthopsilosis and C. metapsilosis, has been frequently implicated in human nosocomial infections in Europe and Latin America. In veterinary medicine, C. parapsilosis sensu lato infections have been reported in different animal species. Several putative virulence factors have been associated with the pathogenicity of this species complex, including biofilm formation and the production of proteases, phospholipases, lipases and other hydrolytic enzymes. Additionally, these species have developed antifungal resistance, especially to azole derivatives and echinocandins. Thus, considering the pathogenic potential of the C. parapsilosis species complex, along with the emergence of antifungal resistant strains, this review was designed to approach historical and biological aspects, microbiological features, virulence factors and antifungal susceptibility traits of C. parapsilosis complex from animals. PMID- 29173585 TI - European surveillance of emerging pathogens associated with canine infectious respiratory disease. AB - Canine infectious respiratory disease (CIRD) is a major cause of morbidity in dogs worldwide, and is associated with a number of new and emerging pathogens. In a large multi-centre European study the prevalences of four key emerging CIRD pathogens; canine respiratory coronavirus (CRCoV), canine pneumovirus (CnPnV), influenza A, and Mycoplasma cynos (M. cynos); were estimated, and risk factors for exposure, infection and clinical disease were investigated. CIRD affected 66% (381/572) of the dogs studied, including both pet and kennelled dogs. Disease occurrence and severity were significantly reduced in dogs vaccinated against classic CIRD agents, canine distemper virus (CDV), canine adenovirus 2 (CAV-2) and canine parainfluenza virus (CPIV), but substantial proportions (65.7%; 201/306) of vaccinated dogs remained affected. CRCoV and CnPnV were highly prevalent across the different dog populations, with overall seropositivity and detection rates of 47% and 7.7% for CRCoV, and 41.7% and 23.4% for CnPnV, respectively, and their presence was associated with increased occurrence and severity of clinical disease. Antibodies to CRCoV had a protective effect against CRCoV infection and more severe clinical signs of CIRD but antibodies to CnPnV did not. Involvement of M. cynos and influenza A in CIRD was less apparent. Despite 45% of dogs being seropositive for M. cynos, only 0.9% were PCR positive for M. cynos. Only 2.7% of dogs were seropositive for Influenza A, and none were positive by PCR. PMID- 29173586 TI - Differential immune-related gene expression in the spleens of duck Tembusu virus infected goslings. AB - Flaviviruses pose a significant threat to public health worldwide. Recently, a novel flavivirus, duck Tembusu virus (TMUV), was identified as the causative agent of a serious duck viral disease in Asia. Its rapid spread and expanded host range have raised substantial concerns regarding its potential threat to non avian hosts, including humans. However, the specific molecular host responses to this virus are poorly understood. In this study, we used the RNA-sequencing technique to analyse the differential gene expression in the spleens of infected goslings 5days post-infection. In total, 2878 upregulated unigenes and 2943 downregulated unigenes were identified. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses revealed that different pattern recognition receptor (PRR) signalling pathways simultaneously participated in the sensing of the pathogen-associated molecular patterns (PAMPs) of TMUV, and the antigen presentation pathway and acquired immunity were activated. Then, the signals were transduced by the NF-kappa B (NF kappaB) or the Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathways, resulting in the enormous production of various cytokines and interferon-stimulated genes (ISGs). We further investigated the immune response patterns in the liver and brain tissue using RT-qPCR. The bacterial peptidoglycan sensor nucleotide-binding oligomerization domain-containing protein 1 (NOD1) receptor was significantly upregulated, especially in the brain tissue, suggesting that NOD1 likely induces an inflammatory response by interacting with dsRNA, which is similar to its actions during hepatitis C viral (HCV) infection. However, major histocompatibility complex II (MHCII) was downregulated only in the spleen, indicating that the downregulation of MHCII in the spleen may be an immune evasion strategy of TMUV to facilitate pathogenesis during infection. Here, we are the first to report a transcriptome analysis of the host immune response to TMUV infection, and the data reported herein may help elucidate the molecular mechanisms of the gosling-TMUV interaction. PMID- 29173587 TI - Interferon alpha inhibits replication of a live-attenuated porcine reproductive and respiratory syndrome virus vaccine preventing development of an adaptive immune response in swine. AB - Type I interferons, such as interferon alpha (IFN-alpha), contribute to innate antiviral immunity by promoting production of antiviral mediators and are also involved in promoting an adaptive immune response. Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most devastating and costly viruses to the swine industry world-wide and has been shown to induce a meager IFN-alpha response. Previously we administered porcine IFN-alpha using a replication-defective adenovirus vector (Ad5-IFN-alpha) at the time of challenge with virulent PRRSV and demonstrated an increase in the number of virus-specific IFNgamma secreting cells, indicating that the presence of IFN-alpha at the time of infection can alter the adaptive immune responses to PRRSV. In the current experiment, we explored the use of IFN-alpha as an adjuvant administered with live-attenuated PRRSV vaccine as a method to enhance immune response to the vaccine. Unlike the previous studies with fully virulent virus, one injection of the Ad5-IFN-alpha abolished replication of the vaccine virus and as a result there was no detectible adaptive immune response. Although IFN-alpha did not have the desired adjuvant effect, the results further highlight the use of IFN-alpha as a treatment for PRRSV infection. PMID- 29173588 TI - A comprehensive study of hepatitis E virus infection in pigs entering a slaughterhouse in Slovenia. AB - Hepatitis E is a zoonotic viral disease of pigs with increasing public health concern in industrialized countries. Presented broad study of hepatitis E virus (HEV) presence in pigs in Slovenia is the first attempt to overview the HEV situation in pigs entering a slaughterhouse and, further, to analyse the possibility of HEV entering into the food supply chain. 2433 samples from 811 clinically healthy pigs were collected at four slaughterhouses in Slovenia. Sampling covered three different age groups of pigs and three different types of samples (faeces, bile and liver) important for tracing HEV in a pig population. In addition, 63 swab samples were collected systematically from three different sites on the slaughter line, as well as 22 samples of minced meat and 30 bratwurst samples. All the samples were screened for the presence of HEV nucleic acids by specific real-time RT-PCR assay. In the group of three month old pigs 13.7% of faeces, 13.0% of bile and 2.1% of liver samples were HEV positive. In the group of six months old pigs only 0.25% of liver and 0.25% of bile samples were positive. In the category of sows, no positive samples were found. Two out of 63 swab samples collected on the slaughter line were HEV positive. All tested samples of minced meat and bratwurst were negative. The phylogenetic analysis of 50 HEV positive samples, with comparison of 366 nucleotides in ORF1 region, revealed high diversity of identified strains of HEV in pigs, belonging into subtypes 3a, 3b, 3c and 3e. PMID- 29173589 TI - EIF3i affects vesicular stomatitis virus growth by interacting with matrix protein. AB - The matrix protein of vesicular stomatitis virus (VSV) performs multiple functions during viral genome replication and virion production and is involved in modulating multiple host signaling pathways that favor virus replication. To perform numerous functions within infected cells, the M protein needs to recruit cellular partners. To better understand the role of M during VSV replication, we looked for interacting partners by using the two-hybrid system. The eukaryotic translation initiation factor 3, subunit i (eIF3i) was identified to be an M binding partner, and this interaction was validated by GST pull-down and laser confocal assays. Through a mutagenesis analysis, we found that some mutants of M between amino acids 122 and 181 impaired but did not completely abolish the M eIF3i interaction. Furthermore, the knockdown of eIF3i by RNA interference decreased viral replication and transcription in the early stages but led to increase in later stages. VSV transcription was increased at 4h post-infection but was not changed at 8 and 12h post-infection after the over-expression of eIF3i. Finally, we also demonstrated that VSV could inhibit the activity of Akt1 and that the knockdown of eIF3i inhibited the expression of the ISGs regulated by phospho-Akt1. These results indicated that eIF3i may affect VSV growth by regulating the host antiviral response in HeLa cells. PMID- 29173590 TI - Gene expression profiling of chicken cecal tonsils and ileum following oral exposure to soluble and PLGA-encapsulated CpG ODN, and lysate of Campylobacter jejuni. AB - Campylobacter jejuni (C. jejuni) is a leading bacterial cause of food-borne illness in humans. Contaminated chicken meat is an important source of infection for humans. Chickens are not clinically affected by colonization, and immune responses following natural infection have limited effects on bacterial load in the gut. Induction of intestinal immune responses may possibly lead to a breakdown of the commensal relationship of chickens with Campylobacter. We have recently shown that soluble and poly D, L-lactic-co-glycolic acid (PLGA) encapsulated CpG oligodeoxynucleotide (ODN) as well as C. jejuni lysate, are effective in reducing the intestinal burden of C. jejuni in chickens; however, the mechanisms behind this protection have yet to be determined. The present study was undertaken to investigate the mechanisms of host responses conferred by these treatments. Chickens were treated orally with soluble CpG ODN, or PLGA encapsulated CpG ODN, or C. jejuni lysate, and expression of cytokines and antimicrobial peptides was evaluated in cecal tonsils and ileum using quantitative RT-PCR. Oral administration of soluble CpG ODN upregulated the expression of interferon (IFN)-gamma, interleukin (IL)-1beta, CXCLi2, transforming growth factor (TGF)-beta4/1, IL-10 and IL-13, while treatment with PLGA-encapsulated CpG ODN upregulated the expression of IL-1beta, CXCLi2, TGF beta4/1, IL-13, avian beta-defensin (AvBD) 1, AvBD2 and cathelicidin 3 (CATHL-3). C. jejuni lysate upregulated the expression of IFN-gamma, IL-1beta, TGF-beta4/1, IL-13, AvBD1, and CATHL-3. In conclusion, induction of cytokine and antimicrobial peptides expression in intestinal microenvironments may provide a means of reducing C. jejuni colonization in broiler chickens, a key step in reducing the incidence of campylobacteriosis in humans. PMID- 29173591 TI - Immunogenicity of a recombinant adenovirus expressing porcine reproductive and respiratory syndrome virus polyepitopes. AB - The objective of this work was to evaluate the immunogenicity of a chimeric antigen containing characterized PRRSV epitopes. A synthetic gene, designated HEJ, encoding defined epitopes was used to generate a recombinant adenovirus designed Ad-HEJ. The chimeric antigen included T-cell epitopes from structural and nonstructural proteins, and a neutralizing B-cell epitope. Following a homologous prime-boost immunization, the Ad-HEJ virus elicited significant (p<0.05) epitope-specific IFN-gamma responses compared to sham-treatment. Two weeks post-challenge, this response was significantly (p<0.05) higher compared to the negative control treatment. IFN-gamma response to PRRSV stimulation in vitro were observed in both groups only after challenge. Antibodies against PRRSV and peptides were detectable following prime-boost immunization in the Ad-HEJ treatment group and the responses increased post-challenge against the virus and against most of the peptides. All the swine were viremic one week post-challenge, but four weeks later, five out of the seven Ad-HEJ vaccinees had cleared the PRRSV, whereas only two of the six negative controls had cleared the virus. The outcome suggests that the adenovirus expressing defined epitopes induced a strong immune response against the peptides, but this response was not sufficient to confer protection against PRRSV challenge. PMID- 29173592 TI - West Nile virus in horses during the summer and autumn seasons of 2015 and 2016, Portugal. AB - West Nile fever (WNF) is an emergent disease in Europe, under surveillance in the European Union. Following a 5-year period of apparent silence (autumn 2010 to summer 2015), West Nile virus (WNV) reemerged in the South of Portugal, in July 2015. Here we present data from the onset, geographic location within mainland Portugal, and outcome of clinical cases of WNV infection in horses in 2015 and 2016. During the transmission seasons of 2015 and 2016, twenty-seven horses, most symptomatic (n=20) were found positive to IgM, pr-E immunoglobulins and VNT, leading to the subsequent report to Animal Disease Notification System of the European Commission (ADNS) by the Portuguese National Authority for Animal Health. Outbreaks occurred in the middle summer (August) and early/mid autumn (October/November) of 2015 and 2016, in the southern regions of the country (Alentejo and Algarve). Compared with the previous WNV transmission seasons of 2004 and 2010, a higher number of cases were reported in 2015 and 2016. The results of our study contribute to increase information concerning the geographic areas affected and time period for WNV transmission risk in Portugal. PMID- 29173593 TI - Molecular and phylogenetic analyses of Salmonella Gallinarum trace the origin and diversification of recent outbreaks of fowl typhoid in poultry farms. AB - Fowl typhoid (FT) and pullorum disease (PD) are two important poultry infections caused by Salmonella enterica subsp. enterica serotype Gallinarum (S. Gallinarum). S. Gallinarum strains are adapted to birds and classified into biovars Gallinarum (bvGA) and Pullorum (bvPU) as they are the causative agent of FT and PD, respectively. In Brazil, FT/PD outbreaks have been reported along the last 50 years, but there was a recent increase of FT field reports with the suspicion it could be due to virulence reversion of the attenuated live vaccine SG9R. In this study, we applied molecular biology assays and phylogenetic methods to detect and investigate S. Gallinarum isolates from commercial poultry flocks in order to understand the evolutionary history and origin of the recent FT outbreaks in Brazil. S. Gallinarum isolates were obtained from thirteen different poultry flocks with clinical signs of FT/PD from 2013 to 2015. These isolates were serotyped, tested with three specific PCR (for the detection of bvGA, bvPU and live vaccine strain SG9R) and submitted to sequencing of a variable genome region (ISR analysis). The complete genome of one bvGA strain (BR_RS12) was also compared to other S. Gallinarum complete genomes (including other two Brazilian ones: bvGA 287/91 and bvPU FCVA198). PCR detected all thirteen isolates as S. Gallinarum (eight bvGA and five bvPU), none positive for SG9R strain. ISR analysis revealed that all eight bvGA isolates showed exactly the same nucleotide sequences with 100% similarity to reference strains, while two patterns were observed for bvPU. Genome phylogeny demonstrated distinct clades for bvGA and bvPU, with the bvGA clade showing a clear subdivision including three genomes: SG9R vaccine, the respective SG9 parent strain and one SG9R revertant field isolate (MB4523). The evolutionary rate of the total S. Gallinarum genome was calculated at 6.15*10-7 substitutions/site/year, with 2.8 observed substitutions per year per genome (1 SNP per 4292 bases). Phylodynamics analysis estimated that at least two introductions of S. Gallinarum bvGA happened in Brazil, the first in 1885 and the second in 1950. The Brazilian bvGA genomes 287/91 and BR_RS12 analyzed here were related to the early and the late introductions, respectively. In conclusion, these results indicate the occurrence of S. Gallinarum strains associated with FT outbreaks that have been circulating for more than 50 years in Brazil and are not originated from virulence reversion of the SG9R vaccine. PMID- 29173594 TI - Serological evidence of hepatitis E virus infection in zoo animals and identification of a rodent-borne strain in a Syrian brown bear. AB - Hepatitis E virus (HEV) is the causative agent of hepatitis E, an emerging infectious disease of humans. HEV infections have also been described in various animal species. Whereas domestic pigs and wild boars are well-known animal reservoirs for HEV, the knowledge on natural HEV infection in zoo animals is scarce so far. Here, we analysed 244 sera from 66 mammal species derived from three zoos in Germany using a commercial double antigen sandwich ELISA. HEV specific antibodies were detected in 16 animal species, with the highest detection rates in suids (33.3%) and carnivores (27.0%). However, RNA of the human pathogenic HEV genotypes 1-4 was not detected in the serum samples from suids or carnivores. Using a broad spectrum RT-PCR, a ratHEV-related sequence was identified in a sample of a female Syrian brown bear (Ursus arctos syriacus). Subsequent serum samples within a period of five years confirmed a HEV seroconversion in this animal. No symptoms of hepatitis were recorded. In a follow-up investigation at the same location, closely related ratHEV sequences were identified in free-living Norway rats (Rattus norvegicus), whereas feeder rats (Rattus norvegicus forma domestica) were negative for HEV-specific antibodies and RNA. Therefore, a spillover infection of ratHEV from free-living Norway rats is most likely. The results indicate that a wide range of zoo animals can be naturally infected with HEV or HEV-related viruses. Their distinct role as possible reservoir animals for HEV and sources of HEV infection for humans and other animals remains to be investigated. PMID- 29173595 TI - Do All Patients With Atrial Fibrillation Need a Cardiologist? PMID- 29173596 TI - The Placebo Effect in Cardiology: Understanding and Using It. AB - The placebo effect is the clinical benefit caused by interaction with a caregiver and health care system in the absence of a biologically active intervention and has been used successfully for millennia. The placebo response results from the interaction of psychosocial mechanisms, human relationships, and preconceptions functioning in specific neuroanatomic locations with known genes and neurotransmitters. It occurs with or without the administration of an inactive substance to deliberately deceive patients. Our purpose is to review the history, benefits, and mechanisms of the placebo effect. The placebo response results from classic conditioning and positive expectations about outcome expressed by the caregiver. The outcomes are usually symptoms such as pain rather than biological outcomes such as death, and the powerful placebo may account for more than half the effect of treatment in many situations. The placebo effect results from activation of opioid, cannabinoid, and dopaminergic pathways involved in reward, expectancy, conditioning, and pain modulation. Eleven specific anatomic features in the brain identified by positron emission tomography and magnetic resonance imaging are involved. Polymorphisms in the structural genes for catecholamine O methyltransferase and fatty acid amide oxidase significantly influence the placebo response. The placebo effect may be important in symptom suppression in angina, paroxysmal atrial fibrillation, and congestive heart failure. In the absence of deliberate deception, there are no ethical issues and given its potency, the time has come to consider how best to use the placebo in clinical practice. PMID- 29173597 TI - Congenital Heart Disease and Neurodevelopment: Clinical Manifestations, Genetics, Mechanisms, and Implications. AB - Children with congenital heart disease (CHD) are at increased risk of neurodevelopmental disorders (NDDs) and psychiatric conditions. These include cognitive, adaptive, motor, speech, behavioural, and executive functioning deficits, as well as autism spectrum disorder and psychiatric conditions. Structural and functional neuroimaging have demonstrated brain abnormalities in young children with CHD before undergoing surgical repair, likely as a result of an in utero developmental insult. Surgical factors do not seem to play a significant role in neurodevelopmental outcomes. Specific genetic abnormalities, particularly copy number variants, have been increasingly implicated in both CHD and NDDs. Variations in genes involved in apolipoprotein E (APOE) production, the Wnt signalling pathway, and histone modification, as well as in the 1q21.1, 16p13.1-11, and 8p23.1 genetic loci, have been associated with CHD and NDDs and are important targets for future research. Understanding these associations is important for risk stratification, disease classification, improved screening, and pharmacologic management of individuals with CHD. PMID- 29173598 TI - Mechanisms, Clinical Significance, and Prevention of Cognitive Impairment in Patients With Atrial Fibrillation. AB - Atrial fibrillation (AF) and dementia are major health issues, with growing evidence suggesting a consistent association between AF and all forms of dementia. Although dementia and AF share several risk factors, the association appears to be independent of a history of clinical stroke and other comorbidities such as hypertension, heart failure, and diabetes. Proposed mechanisms linking AF to cognitive decline include altered hemodynamics resulting in cerebral hypoperfusion, inflammation, genetic factors, and silent cerebral ischemia due to subclinical microemboli. Evidence in support of the microembolization hypothesis includes the much higher incidence of silent cerebral ischemia detected in imaging studies in patients with AF, the association between presence of silent cerebral ischemia and cognitive dysfunction, and a "dose response" relationship between extent of silent cerebral ischemia and degree of cognitive impairment. Preventive therapies are currently being investigated and include anticoagulation, antiplatelet therapy, statins, pharmacological rhythm and rate control treatment strategies for AF, and catheter ablation procedures. Blinded Randomized Trial of Anticoagulation to Prevent Ischemic Stroke and Neurocognitive Impairment in Atrial Fibrillation (BRAIN-AF) trial is currently assessing whether oral anticoagulation can prevent cognitive decline in patients at low risk of overt stroke. Considering the strong and independent association between AF and neurocognitive outcomes and the major clinical implications, evidence-based preventive approaches are critically required to diminish the health burden from the scourge of dementia and related conditions. PMID- 29173599 TI - Bipolar Disorder and the Vascular System: Mechanisms and New Prevention Opportunities. AB - Bipolar disorder (BD) is associated with excessive prevalence and premature onset of cardiovascular disease (CVD). This association is observed internationally in clinical as well as predominantly untreated epidemiologic samples. A number of factors might explain this association in part, including excessive rates of traditional cardiovascular risk factors (CVRFs), suboptimal lifestyle behaviour s relating to physical activity, nutrition, and use of alcohol, tobacco, and drugs, and the use of psychiatric medications with propensity for causing CVRFs. Nonetheless, compelling findings from predominantly untreated representative population samples indicate the increased risk of CVD among people with BD likely exceeds what can be explained by these factors. In this narrative review, I summarize the clinical epidemiology linking BD and CVD, and the previously reviewed biological processes that might be contributory, including excessive inflammation, and summarize a growing body of literature from the author's research group regarding vascular factors among adolescents with BD, a group of patients that is highly amenable to the potential benefits of preventive cardiology approaches. Finally, I elaborate on a hypothesis that microvascular phenotypes might explain in part the "extra" risk of CVD that is not explained by traditional CVRFs. PMID- 29173600 TI - A Practical Approach to Avoiding Cardiovascular Adverse Effects of Psychoactive Medications. AB - Drugs that act on mental state, generally termed "psychoactive agents," are among the most widely used medications in medicine. Psychoactive agents can affect the cardiovascular system and must be used carefully to avoid negative cardiovascular consequences. In the present article we review the potential adverse cardiovascular consequences of psychoactive medications and provide suggestions for practical approaches to avoiding them. We consider adverse reactions in terms of: (1) arrhythmias (particularly acquired long QT syndrome); (2) blood pressure; (3) ventricular function; (4) effect on risk factors; (5) teratogenicity; and (6) drug interactions. Minimizing QT liability requires a consideration of patient specific risk factors and the risk profile of drugs available to treat the psychiatric condition. Drugs with QT-prolonging properties can be used safely, provided that appropriate precautions are taken. Fear of QT-prolongation should not deprive patients of needed psychiatric therapy. For example, one large study reported substantially increased all-cause mortality/hospitalization, death/depression-hospitalization, and death/arrhythmia-hospitalization in patients for whom citalopram dosage was reduced over QT-concerns after the Food and Drug Administration Black Box Warning. In general, attention to drug-specific cardiac adverse effect risks is needed, along with appropriate patient-related drug selection and follow-up, to detect adverse reactions early and adjust accordingly. Treatment should begin with low doses, followed by careful dose titration and adjustment of drug regimen according to clinical responses. Particular care is needed to minimize negative consequences on cardiovascular/metabolic risk profile, which might have very detrimental long term effects on cardiovascular health. It is crucial that fear of cardiovascular adverse effects not deprive patients of appropriate psychoactive drug-therapy.

AB - BACKGROUND: Randomized controlled trials (RCTs) on bone marrow stem cell (BMSC) therapy in ST-elevation myocardial infarction (STEMI) patients have reported conflicting results. Our main objective was to critically appraise and meta analyze best-available evidence on efficacy and safety of intracoronary administration of autologous BMSC therapy in STEMI patients after primary percutaneous coronary intervention. METHODS: We conducted a search of MEDLINE, PubMed, EMBASE, CENTRAL, Global Health, CINAHL, and conference proceedings in February 2017. Our primary outcome was all-cause mortality. Secondary and safety outcomes included cardiac death, heart failure, arrhythmias, repeat myocardial infarction, or target vessel revascularizations; or improved health-related quality of life, left ventricular ejection fraction, or infarct size. Summary relative and absolute risks were obtained using random effects models. We also evaluated the strength of evidence. RESULTS: A comprehensive database search identified 42 RCTs (3365 STEMI patients). BMSC therapy did not significantly decrease mortality (risk ratio, 0.71; 95% confidence interval, 0.45-1.11; I2, 0%; absolute risk reduction, 0.1%; 95% confidence interval, -0.71 to 0.91; 40 trials; 3289 participants; I2, 0%; low strength of evidence). BMSC therapy had no effect on secondary or adverse outcomes. Trial sequential analysis for all-cause mortality showed no evidence of a clinically important difference, with a very low probability that future studies can change the current conclusion. CONCLUSIONS: On the basis of evidence from 42 RCTs published in the past 15 years, we provide conclusive evidence for a lack of beneficial effect for autologous BMSC therapy in patients with STEMI. PMID- 29173602 TI - Association Between Circulating Oxidized LDL and Atherosclerotic Cardiovascular Disease: A Meta-analysis of Observational Studies. AB - BACKGROUND: Although basic research has suggested that oxidized low-density lipoprotein (ox-LDL) is involved in the pathogenesis of atherosclerosis, population observational studies have yielded conflicting results about the association between circulating ox-LDL and atherosclerotic cardiovascular disease (ASCVD). Therefore, we performed a systematic review and meta-analysis of currently available observational studies to verify the association between circulating ox-LDL and ASCVD. METHODS: We systematically searched PubMed and the Cochrane Library from their inception to March 27, 2017, for nested case-control studies, case-cohort studies, and prospective cohort studies on the relationship between ox-LDL and ASCVD. Studies that did not assess the hazard ratio, relative risk, or odds ratio of ox-LDL or did not adjust for other risk factors, or those without examination of ox-LDL before collection of ASCVD occurrences were excluded. The summarized effect size was combined using fixed effect models. Subgroup analyses were performed on the basis of study quality, study design, definition of ASCVD events, effect size types, types of ox-LDL assay, ox-LDL contrast level, and whether low-density lipoprotein cholesterol was adjusted in a multivariate model. RESULTS: A total of 12 included studies consisted of 3 nested case-control studies, 1 case-cohort study, 5 hospital-based cohort studies, and 3 community-based cohort studies. The summary effect size of increased circulating ox-LDL was 1.79 (95% confidence interval, 1.56-2.05) for ASCVD. Similar associations were shown in all subgroups. CONCLUSIONS: Our findings indicate that increased levels of circulating ox-LDL are associated with clinical ASCVD events. Further well designed community-based cohort studies or intervention studies are needed to confirm our findings. PMID- 29173603 TI - Comparison of Different Automated Office Blood Pressure Measurement Devices: Evidence of Nonequivalence and Clinical Implications. AB - BACKGROUND: Automated office blood pressure (AOBP) measuring devices are increasingly recommended as preferred blood pressure (BP) diagnostic tools, but it is unclear how they compare and how clinical environments impact their performance. METHODS: This prospective randomized factorial parallel 4-group study compared BP estimates by BpTRU (VSM MedTech, Vancouver, BC, Canada) and Omron HEM 907 (Omron Healthcare, Kyoto, Japan) devices in closed vs open areas. Patients diagnosed with hypertension were recruited during office visits. After baseline open-room AOBP measurement with the BpTRU, patients had a second BP measurement with either the BpTRU or HEM 907 in either open or closed areas. Absolute BP levels and differences between the first and second measurements were compared. Diagnostic performance was also assessed. RESULTS: Two hundred fifty eight patients were studied. Their mean age was 66.2 +/- 12.0 years, and 62% were men. The mean of first AOBP estimates was 127.4/73.3 mm Hg. Analyses of subsequent measurements revealed no influence of open or closed areas on BP means and diagnostic performance. Conversely, the Omron HEM 907 exceeded BpTRU systolic BP measurements by 4.6 mm Hg (< 0.01) in closed areas and by 3.9 mm Hg (< 0.01) in open areas. The discrepancy between devices was amplified at lower BP levels. CONCLUSIONS: Although different areas did not influence BP estimates, the Omron HEM 907 significantly exceeded BpTRU measurements on average and especially at lower BP levels. These differences should be considered when interchanging devices and could have clinical decision impacts in a population of patients treated for hypertension. Our results support the constant use of only 1 device type in a given clinic. PMID- 29173604 TI - The Impact of Burst Exercise on Cardiometabolic Status of Patients Newly Diagnosed With Type 2 Diabetes. AB - BACKGROUND: The impact of burst high-intensity exercise on physiological, cardiometabolic, and biochemical variables compared with traditional moderate intensity continuous exercise training (MICT) has yet to be assessed in patients with type 2 diabetes (T2D). We compared the impact of multiple short-duration, high-intensity burst exercise sessions to MICT on cardiometabolic variables in patients with T2D. METHODS: Forty newly diagnosed patients with T2D not receiving lipid lowering or hypoglycemic medications were randomized to 40 minutes of MICT (60% of maximal heart rate) 5 days per week or 3 continuous bursts of 12 minutes of high-intensity exercise (85% of maximal heart rate) 5 days per week for 3 months. Body mass index, hemoglobin A1C (HbA1C), and lipid profile were assessed before and after 3 months of exercise training. RESULTS: Burst exercise resulted in greater body mass index reduction than did MICT (-2.1 +/- 1.2 kg/m2 vs -0.7 +/ 0.7 kg/m2, respectively; P < 0.05). There was a greater reduction at 3 months (P < 0.05) in HbA1C levels in the burst exercise group (8.14% +/- 0.49% to 7.32% +/- 0.39%) compared with the MICT group (8.18% +/- 0.35% to 7.94% +/- 0.41%). Compared with MICT, burst exercise was associated with a greater reduction in low density lipoprotein cholesterol (-11 vs -4%; P < 0.05) and a greater increase in high-density lipoprotein cholesterol (22% vs 3%; all P < 0.05). After 3 months, patients in the burst exercise group attained greater exercise time on the treadmill (exercise capacity) than did those prescribed MICT (6.87 +/- 1.44 minutes vs 5.40 +/- 1.96 minutes; P < 0.001). CONCLUSIONS: Findings from the current study support better cardiometabolic benefits of burst exercise compared with MICT over 3 months in patients with newly diagnosed T2D. PMID- 29173605 TI - Prognostic Value of Psoas Muscle Area and Density in Patients Who Undergo Cardiovascular Surgery. AB - BACKGROUND: Low skeletal muscle density, determined using computed tomography (CT), has yet to be examined in terms of muscle function and prognostic capability in patients who require open cardiovascular surgery. This study was performed to examine whether psoas muscle area and density, determined using CT, are associated with postoperative mortality in patients who undergo cardiovascular surgery. METHODS: We reviewed the findings in 773 consecutive patients who underwent preoperative CT imaging, including the level of the third lumbar vertebra for clinical purposes. We measured grip strength, gait speed, and 6-minute walking distance to assess muscle function before hospital discharge. Skeletal muscle area was calculated from psoas muscle cross-sectional area (in squared centimeters) on preoperative CT images at the level of the third lumbar vertebra divided by the square of the patient's height in metres to give the skeletal muscle index (SMI). Skeletal muscle density determined by muscle attenuation (MA) was calculated by measuring the average Hounsfield units of the psoas muscle cross-sectional area. RESULTS: The mean age of the study population was 65.0 +/- 13.1 years, and 64.7% of the patients were male. Multivariate logistic regression analysis and multivariate Cox regression analysis showed that low MA, but not SMI, was significantly associated with muscle function, and all cause mortality (P < 0.05). Kaplan-Meier analysis showed that low MA, but not low SMI, predicted mortality (P = 0.014). CONCLUSIONS: Low skeletal muscle density, but not skeletal muscle area, predicted poorer muscle function and mortality in patients who undergo cardiac surgery. PMID- 29173606 TI - Antiplatelet Effect of Different Loading Doses of Ticagrelor in Patients With Non ST-Elevation Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention: The APELOT Trial. AB - BACKGROUND: We hypothesized that a high ticagrelor loading dose (LD) may improve platelet inhibition in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) undergoing percutaneous coronary intervention (PCI). METHODS: This interventional multicentre open-label trial randomized 278 patients with NSTE-ACS to a high (360 mg) or conventional (180 mg) ticagrelor LD. The primary outcome was the platelet reactivity index (PRI) 1 hour after administration of the LD. Secondary outcomes included PRI at 0.5 hour, 1 hour, 8 hours, and 24 hours; periprocedural myocardial infarction (PMI); major cardiac adverse events; and bleeding events. RESULTS: Two hundred sixty-two patients completed the major end points. PRI was lower in the high-LD group than in the conventional-LD group at any time point (all, P < 0.05), including at 1 hour (12.2% vs 16.7%; P = 0.023). At 0.5 hour, the high-LD group showed a lower high-platelet reactivity rate (49.6% vs 60.2%; P = 0.013) and a higher low-platelet reactivity rate (24.8% vs 12.8%; P = 0.017) than did the conventional LD group. No significant differences in the bleeding rates were found between the 2 groups (14% vs 14.3%). Four cases of PMI and 1 death in each group, as well as 1 acute myocardial infarction in the conventional LD group, occurred. There was no stroke, target lesion revascularization, or target vessel revascularization. CONCLUSIONS: Doubling the ticagrelor LD achieved faster onset and greater platelet inhibition without an increase in adverse events in patients with NSTE-ACS undergoing PCI. PMID- 29173607 TI - Clinical Features and Outcomes of Acute Coronary Syndrome in Women With Previous Pregnancy Complications. AB - BACKGROUND: Women with previous cardiometabolic complications of pregnancy experience double the risk of cardiovascular disease. However, few data exist on the clinical effect of these complications at the time of an acute coronary syndrome (ACS). The objective of this work was to compare risk factors, clinical features, and outcomes among women with premature ACS with or without previous pregnancy complications (gestational diabetes and/or hypertensive disorders of pregnancy). METHODS: Data were obtained from a multicentre cohort of individuals hospitalized with premature ACS. A total of 251 parous women were included and provided obstetric history and blood samples. They were followed for the development of major adverse cardiac events at 12 months. RESULTS: At presentation with ACS, women with a previous pregnancy complication (38%) were slightly younger than were women without such complications (47.4 +/- 6.2 vs 49.1 +/- 5.6 years; P = 0.002). They also had more traditional atherosclerotic risk factors. Specifically, women with previous preeclampsia were more likely to have chronic hypertension and an elevated ratio of soluble fms-like tyrosine kinase:placental growth factor. There was no between-group difference in Global Registry of Acute Coronary Events (GRACE) score or troponin tertile but there was a trend toward higher risk of ST-elevation myocardial infarction in women who had a previous pregnancy complication (odds ratio, 1.80; 95% confidence interval, 1.00-3.23; P = 0.05). There was also an increased risk of recurrent ACS at 12 months in women with previous preeclampsia (hazard ratio, 6.79; 95% confidence interval, 1.37-33.63; P = 0.02). CONCLUSIONS: Among a cohort of women with ACS, previous pregnancy complications were associated with more severe disease and poorer outcome. PMID- 29173608 TI - The Relationship Between Cardiologist Care and Clinical Outcomes in Patients With New-Onset Atrial Fibrillation. AB - BACKGROUND: Increased mortality is well described in patients with atrial fibrillation (AF), primarily related to death from cardiovascular causes. One may hypothesize that cardiology care may be associated with a reduction in cardiovascular deaths in patients with AF, thereby improving their overall survival. The aim of this study was to assess the association between cardiologist care and clinical outcomes, including all-cause mortality, in patients with new-onset AF. METHODS: This was a retrospective population-level, propensity score-matched cohort study of patients aged 20-80 years with new-onset AF presenting to an emergency department in Ontario, Canada between 2010 and 2012. Patients who saw a cardiologist within 1 year of the initial diagnosis were matched to patients who did not see a cardiologist. Linked administrative databases were used for cohort construction and allow for 1-year follow-up to assess for the clinical end points of death, hospitalization for AF, stroke syndromes, bleeding, and heart failure. RESULTS: Cardiologist care was associated with a lower 1-year rate of death (5.3% vs 7.7%; hazard ratio, 0.68; 95% confidence interval, 0.55-0.84), despite an increased rate of hospitalizations for AF (17.9% vs 8.2%), stroke syndromes (1.7% vs 0.5%), bleeding (3.1% vs 2.0%), and heart failure (3.2% vs 1.4%). CONCLUSIONS: Cardiologist care was associated with a reduction in death in patients with new-onset AF. Further study to obtain a greater understanding of the processes of care associated with the observed survival improvement is warranted. PMID- 29173609 TI - Effects of Patent Foramen Ovale Closure on Obstructive Sleep Apnea Syndrome: PCOSA Study. AB - BACKGROUND: Previous studies have shown a higher prevalence of patent foramen ovale (PFO) in patients with obstructive sleep apnea syndrome (OSAS). Right to left shunting through a PFO may be encouraged by the respiratory physiology of OSAS, contributing to the disease pathophysiology. We assessed whether PFO closure would improve respiratory polygraphy parameters compared with baseline measurements in patients with OSAS. METHODS: Twenty-six patients with newly diagnosed OSAS and a moderate-large PFO (prevalence, 18% of 143 patients screened) were referred for PFO closure. The oxygen desaturation index (ODI), apnea-hypopnea index (AHI), Epworth Sleepiness Scale (ESS), 6-minute walk test (6MWT), and Sleep Apnea Quality of Life Index (SAQLI) results were compared in these patients at baseline (before continuous positive pressure ventilation [CPAP]) and at 6-month follow-up (after interrupting CPAP for 1 week). RESULTS: All PFOs were safely sealed at 6 months, as confirmed by repeated transthoracic echocardiography. The ODI (44.8 [interquartile range (IQR), 31.2-63.5) vs 42.3 [IQR, 34.0-60.8]; P = 0.89) and AHI (47.9 [IQR, 31.5-65.2] vs 42.3 [IQR, 32.1 63]; P = 0.99) did not change after PFO closure nor did the 6MWT, although the ESS (13.0 [IQR, 12.0-16.8] vs 6.0 [IQR, 4.0-8.8]; P < 0.001) and the SAQLI (3.4 [IQR, 2.8-4.3] vs 4.4 [IQR, 3.9-5.3]; P < 0.001) did improve. CONCLUSIONS: The prevalence of PFO in OSAS appears to be no higher than that in the general population. Although PFO closure is safe and effective, it did not improve respiratory polygraphy measures of OSAS severity. The improvement in the ESS and SAQLI likely reflect residual benefits from CPAP. PMID- 29173610 TI - Endothelial Nitric Oxide Synthase-Induced Hypertrophy and Vascular Dysfunction Contribute to the Left Ventricular Dysfunction in Caveolin-1-/- Mice. AB - BACKGROUND: Caveolin-1 (Cav1)-/- mice display impaired development of left ventricular pressure and increased left ventricular wall thickness but no dilated ventricle; these are typical findings in patients with heart failure with preserved ejection fraction (HfpEF). Aiming to clarify if dysfunctional endothelial nitric oxide synthase (eNOS) influences cardiomyocyte contractility, cardiac conduction system, or afterload/vascular resistance, we studied Cav1-/ /eNOS-/- mice. METHODS: Cardiac function was assessed in vivo by pressure-volume catheterization of the left ventricle, echocardiography and electrocardiography. In addition, isolated tissue experiments were performed to evaluate cardiomyocyte contractility (atria) and vessel morphology and function (aorta). Histology, immunoblotting and quantitative polymerase chain reaction were applied to characterise radical formation and oxidative stress in the heart. RESULTS: Cardiac hypertrophy was completely reversed in Cav1-/-/eNOS-/- mice. The impaired pump function in Cav1-/- mice was significantly improved in Cav1-/-/eNOS-/- mice, but no complete alignment with eNOS-/- controls was achieved, indicating an additional eNOS-independent mechanism contributing to HFpEF in Cav1-/- mice. It is unlikely that frequently occurring arrhythmias contributed to HFpEF in Cav1-/- mice. In contrast, numerous eNOS-dependent and eNOS-independent vascular abnomalities could explain the cardiac phenotypes of Cav1-/- mice. CONCLUSIONS: Synergistic effects between eNOS-related cardiac hypertrophy and vascular hypercontractility appear to underlie the left ventricular dysfunction in Cav1-/ mice. These findings provide insights relevant to the poorly understood pathophysiology of HFpEF. PMID- 29173611 TI - A Novel Pacing Strategy With Low and Stable Output: Pacing the Left Bundle Branch Immediately Beyond the Conduction Block. AB - This report demonstrates the feasibility of pacing the left bundle branch (LBB) immediately beyond the conduction block to functionally restore the impaired His Purkinje conduction system in a patient with heart failure and left bundle branch block (LBBB). The pacing required only a low pacing output (0.5 volts/0.5 ms) to correct the LBBB with accompanying right BBB on the electrocardiogram. Over 1 year of follow-up, the patient had a significant improvement in clinical outcome and echocardiographic measurements. The case shows a novel pacing strategy for patients with BBB that affects many patients with heart failure. PMID- 29173612 TI - A Case of Spontaneous Coronary Artery Dissection Complicated by Free Wall Rupture. AB - Spontaneous coronary artery dissection (SCAD) is an unusual and underdiagnosed cause of nonatherosclerotic acute coronary syndrome (ACS). Patients might present in various ways including chest pain, ST-elevation ACS, ventricular arrhythmia, and sudden cardiac death. In a few reports, it manifested initially as cardiac tamponade. The association of SCAD with free wall rupture is extremely rare. We present a unique case of a 70-year-old woman who initially presented with non-ST elevation ACS and was found to have SCAD on angiography, which was subsequently complicated by cardiac tamponade with free wall rupture. PMID- 29173613 TI - Pregnancy in Women With Repaired Truncus Arteriosus: A Case Series. AB - Pregnancy in women with repaired truncus arteriosus (TA) is rare. We report the outcomes of 8 pregnancies in 4 women with surgically repaired TA. None of the women had adverse cardiac events during pregnancy. Two pregnancies, both in the same woman, were complicated by hypertensive disorders of pregnancy. The birth weight was less than the 10th percentile for gestational age in 3 pregnancies. Although women with repaired TA can do well during pregnancy, they require careful preconception assessment and surveillance. PMID- 29173615 TI - Inactivation of murine norovirus and hepatitis A virus on fresh raspberries by gaseous ozone treatment. AB - Raspberries are vulnerable products for which industrial treatment solutions ensuring both food safety and sensory quality are not easily applicable. Raspberries have been associated with numerous foodborne outbreaks in recent decades. Ozone has been proven effective as a drinking water treatment against pathogenic microorganisms. Nevertheless, to date, little information is available regarding the effect of gaseous ozone on viruses in food matrices. A comparison of the effect of gaseous ozone on murine norovirus (MNV-1) and hepatitis A virus (HAV) adsorbed on fresh raspberries was performed. Infectious MNV-1 was highly inactivated (>3.3 log10) by ozone (3 ppm, 1 min). The raspberry matrix seems to enhance inactivation by ozone compared to water. The same treatment was observed to have little effect on HAV even for the highest dose under the tested conditions (5 ppm, 3 min). Ozone treatment (5 ppm, 3 min) did not affect the appearance of raspberries even after three days post-treatment. No ozone effect was observed on the genomes detected by RT-PCR on both tested viruses, irrespective of the matrix or tested doses used. Gaseous ozone could therefore be a good candidate for human norovirus inactivation on raspberries but new conditions are needed for it to have significant effects on HAV inactivation. PMID- 29173614 TI - Pregnancy After Transcatheter Pulmonary Valve Implantation. AB - Transcatheter pulmonary valve implantation (TPVI) is a relatively new method of treating patients with significant pulmonary regurgitation or pulmonary stenosis, or both, after reconstruction of the right ventricular outflow tract. It is an attractive alternative to conduit replacement in this group of patients, who are typically young and active. This report includes 4 young women who after successful TPVI became pregnant and gave birth. Transthoracic echocardiography, cardiopulmonary exercise testing, and cardiac magnetic resonance imaging were performed in all patients. The results suggest that pregnancy and delivery after successful TPVI is safe when the appropriate precautions have been taken. PMID- 29173616 TI - Efficacy of Pseudomonas graminis CPA-7 against Salmonella spp. and Listeria monocytogenes on fresh-cut pear and setting up of the conditions for its commercial application. AB - Pseudomonas graminis CPA-7 has been reported to control foodborne pathogens on fresh-cut apple, peach and melon. The first aim of this study was to assess its antagonistic activity against Salmonella spp. and L. monocytogenes on fresh-cut pear. CPA-7 was able to control both pathogens on fresh-cut pear stored in air conditions at 5, 10 and 20 degrees C. However, when CPA-7 antagonistic effect was tested by simulating commercial application (with antioxidant solution and passive modified atmosphere packaging), its effect decreased and no reductions of foodborne pathogens were reported at 10 degrees C. Therefore, the second aim was to optimise the antioxidant solution and the packaging in order to retain its antagonistic capacity. The selected antioxidant solution was 2% ascorbic acid +2% sodium citrate +1% CaCl2 according to growth and effect of CPA-7. Film permeability, which affects gas composition inside fruit packages, influenced CPA 7 efficacy. If the biopreservative strain is used, film has to be sufficiently gas permeable to allow CPA-7 function and at the same time to maintain product quality. PMID- 29173617 TI - Identification of Brucella genus and eight Brucella species by Luminex bead-based suspension array. AB - Globally, unpasteurized milk products are vehicles for the transmission of brucellosis, a zoonosis responsible for cases of foodborne illness in the United States and elsewhere. Existing PCR assays to detect Brucella species are restricted by the resolution of band sizes on a gel or the number of fluorescent channels in a single real-time system. The Luminex bead-based suspension array is performed in a 96-well plate allowing for high throughput screening of up to 100 targets in one sample with easily discernible results. We have developed an array using the Bio-Plex 200 to differentiate the most common Brucella species: B. abortus, B. melitensis, B. suis, B. suis bv5, B. canis, B. ovis, B. pinnipedia, and B. neotomae, as well as Brucella genus. All probes showed high specificity, with no cross-reaction with non-Brucella strains. We could detect pure DNA from B. abortus, B. melitensis, and genus-level Brucella at concentrations of <=5 fg/MUL. Pure DNA from all other species tested positive at concentrations well below 500 fg/MUL and we positively identified B. neotomae in six artificially contaminated cheese and milk products. An intra-laboratory verification further demonstrated the assay's accuracy and robustness in the rapid screening (3-4 h including PCR) of DNA. PMID- 29173618 TI - Association between bacterial survival and free chlorine concentration during commercial fresh-cut produce wash operation. AB - Determining the minimal effective free chlorine (FC) concentration for preventing pathogen survival and cross-contamination during produce washing is critical for developing science- and risk-based food safety practices. The correlation between dynamic FC concentrations and bacterial survival was investigated during commercial washing of chopped Romaine lettuce, shredded Iceberg lettuce, and diced cabbage as pathogen inoculation study during commercial operation is not feasible. Wash water was sampled every 30 min and assayed for organic loading, FC, and total aerobic mesophilic bacteria after chlorine neutralization. Water turbidity, chemical oxygen demand, and total dissolved solids increased significantly over time, with more rapid increases in diced cabbage water. Combined chlorine increased consistently while FC fluctuated in response to rates of chlorine dosing, product loading, and water replenishment. Total bacterial survival showed a strong correlation with real-time FC concentration. Under approximately 10 mg/L, increasing FC significantly reduced the frequency and population of surviving bacteria detected. Increasing FC further resulted in the reduction of the aerobic plate count to below the detection limit (50 CFU/100 mL), except for a few sporadic positive samples with low cell counts. This study confirms that maintaining at least 10 mg/L FC in wash water strongly reduced the likelihood of bacterial survival and thus potential cross contamination of washed produce. PMID- 29173619 TI - Predictive modeling of bacterial growth in ready-to-use salted napa cabbage (Brassica pekinensis) at different storage temperatures. AB - The objectives of the current study were to investigate the fate of microbial indicators [aerobic plate counts (APC), total coliforms (TC), and lactic acid bacteria (LAB)] in commercial salted napa cabbages during storage conditions at different temperatures (5, 22, and 30 degrees C, for up to 72 h) and to develop a predictive growth model using the modified Gompertz equation to determine shelf life. Microbial population sizes (initial log CFU g-1: APC, 5.1; TC, 3.0; LAB, 3.7) remained stable at 5 degrees C, but rapidly increased by 2-4 log CFU g-1 within 12 h at 22 and 30 degrees C; furthermore, the pH of salted napa cabbages decreased significantly (P < 0.05: initial pH 6.3; final pH 4.1-4.4) due to LAB fermentation. The pH showed a negative correlation with all bacterial groups and did not prevent the growth of TC during storage. According to the modified Gompertz model (R2 ? 0.97), the highest MUmax was observed for LAB at 30 degrees C [0.61 log CFU h-1], while the lowest was noted for TC at 5 degrees C [0.04 log CFU h-1]. Shelf-life was determined using APC (7.7 log CFU g-1) and LAB (6.0 log CFU g-1) limits; the microbiological acceptability period of salted napa cabbage was predicted to be 12.6 and 9.3 h at 22 and 30 degrees C, respectively. Thus, consumers should use the product within 12 h of storage at room temperature (more quickly in the summer (9 h)), or store it in a refrigerator. The presented research proposes a shelf-life modeling of commercial salted napa cabbages, which may be used as a scientific basis for product quality control and issuing appropriate guidance for consumer use at home. PMID- 29173620 TI - Loop-Mediated Isothermal Amplification-Lateral-Flow Dipstick (LAMP-LFD) to detect Toxoplasma gondii oocyst in ready-to-eat salad. AB - The apicomplexan parasite Toxoplasma gondii is the causative agent of toxoplasmosis, a foodborne zoonosis with a global distribution and estimated to cause up to 20% of the total foodborne disease burden in Europe. Association between T. gondii infection and the consumption of unwashed raw fruits and vegetables contaminated with oocysts has been reported and the increasing habit to eat pre-washed ready-to-eat salads poses a new potential risk for consumers. It is therefore important to trace the occurrence of potential contamination with this parasite to guarantee the safety of ready-to-eat vegetables. Detection of T. gondii in vegetables by molecular techniques has been achieved but low sensitivity (PCR) or expensive equipments (qPCR) limit routine applicability. Here, we describe the development and validation of a sensitive and robust method relying on a LAMP assay, targeting the 529 bp locus, to detect T. gondii oocysts down to 25 oocysts/50 g in ready-to-eat baby lettuce. The LAMP has been also adapted for a faster visualization of the result by a lateral flow dipstick chromatographic detection method. PMID- 29173621 TI - Polyphasic approach to study physico-chemical, microbiological and sensorial characteristics of artisanal Nicastrese goat's cheese. AB - Nicastrese goat's cheese is produced in the South of Italy under traditional procedures, from raw goat milk without any starter cultures addition. Samples from milk to ripened cheese provided by 4 different farms were subjected to a polyphasic approach to study their physico-chemical, microbiological and sensorial characteristics. In addition, volatile organic compounds formation in the final products was studied. Overall, gross composition and microbiological data revealed a significant variability among samples, which was confirmed by both the volatile organic compounds generated in the final products and by the sensorial data. Conventional technique allowed us to identify 720 isolates, mainly belonging to Lactococcus lactis, Lactobacillus plantarum, Lactobacillus casei, Lactobacillus brevis, Leuconostoc mesenteroides, and Enterococcus faecalis. Culture-independent methods revealed shifts in the microbial community structure, with an increase in biodiversity of metabolically active bacterial species, from milk to cheese samples. Analysis of volatile organic compounds (VOCs) allowed the identification of 36 compounds; free fatty acids and ketones represented the main detected, followed by alcohols and esters. Moreover, statistical analysis was performed in order to correlate VOCs to bacterial species. Data showed that ester compounds as well as alcohol and aldehydes were positively correlated to NSLAB, indicating that the occurrence of L. casei, L. plantarum and L. brevis species is relevant for the VOCs formation in the final product. PMID- 29173622 TI - Impact of relative humidity, inoculum carrier and size, and native microbiota on Salmonella ser. Typhimurium survival in baby lettuce. AB - The effects of relative humidity (RH), fluctuating climate conditions, inoculum size and carrier on the survival of Salmonella enterica serovar Typhimurium on baby lettuce in environmental test chambers were studied. Buffered peptone water (BPW), distilled water (DW), and irrigation water (IW) were compared as inoculum carriers. Additionally, survival of Salmonella in suspensions prepared using filtered and unfiltered IW was assessed. Salmonella Typhimurium survived better on baby lettuce plants at high RH independently of the inoculum size. When lettuce plants were grown under fluctuating environmental conditions, Salmonella survival was similar under both RH conditions. Regarding the inoculum carrier, the inoculated microorganism survived better on lettuce plants when BPW was used as carrier both at high and low RH. Survival rate of Salmonella in IW was affected by the presence of native microbiota. Native microbiota present in IW did not affect survival of Salmonella or the levels of mesophilic bacteria on the baby lettuce leaves. The information obtained in the present study contributes to the knowledge on the effect of environmental conditions on pathogenic bacteria survival on growing edible plants. These results are useful when selecting the methodology to carry out experimental studies on the survival of microbial pathogens under different pre-harvest conditions. PMID- 29173623 TI - Wheat endophytic lactobacilli drive the microbial and biochemical features of sourdoughs. AB - The aim of this study was to assess whether wheat endophytic lactic acid bacteria (LAB) are able to dominate in sourdough ecosystem. To do that, a first experimental phase considered doughs produced under semi-sterile conditions and singly inoculated with different strains of endophytic LAB and Lactobacillus sanfranciscensis A4 isolated from sourdough. Notwithstanding the high frequency of Lactobacillus plantarum in the sourdoughs prepared in laboratory, only one of the starter strains, L. plantarum LB2, was detected after five days of back slopping. Subsequently, the ability of this strain to dominate traditional sourdoughs was evaluated at bakery and laboratory level. Contamination of sourdoughs with L. plantarum LB2 caused an increased number of LAB and, accordingly, higher acidification, compared to the sourdoughs before this event. After six days of propagation, the wheat endophytic strain L. plantarum LB2 was retrieved as a component of the bacterial population, in all the sourdoughs and regardless of the place of propagation. In addition, the contamination event caused a modification of the lactic acid bacterium biota, which in turn influenced some sourdoughs biochemical features. In conclusion, this study showed that wheat endophytic LAB could represent a potential reservoir for selecting robust strains to be used as sourdough starters. PMID- 29173624 TI - Causal agents of Fusarium head blight of durum wheat (Triticum durum Desf.) in central Italy and their in vitro biosynthesis of secondary metabolites. AB - Durum wheat samples harvested in central Italy (Umbria) were analyzed to: evaluate the occurrence of the fungal community in the grains, molecularly identify the Fusarium spp. which are part of the Fusarium head blight (FHB) complex and characterize the in vitro secondary metabolite profiles of a subset of Fusarium strains. The Fusarium genus was one of the main components of the durum wheat fungal community. The FHB complex was composed of eight species: Fusarium avenaceum (61%), F. graminearum (22%), F. poae (9%), F. culmorum (4%), F. proliferatum (2%), F. sporotrichioides (1%), F. sambucinum (0.5%) and F. langsethiae (0.5%). F. graminearum population was mainly composed of the 15 acetyldeoxynivalenol chemotype, while, F. culmorum population was composed of the 3-acetyldeoxynivalenol chemotype. In vitro characterization of secondary metabolite biosynthesis was conducted for a wide spectrum of substances, showing the mycotoxigenic potential of the species complex. F. avenaceum strains were characterized by high enniantin and moniliformin production. F. graminearum strains were in prevalence deoxynivalenol producers. F. poae strains were characterized by a high biosynthesis of beauvericin like the F. sporotrichioides strain which was also found to be a high T-2/HT-2 toxins producer. Production of aurofusarin, butenolide, gibepyrone D, fusarin C, apicidin was also reported for the analyzed strains.

AB - The objective of this study was to determine the effect of strain and temperature on the growth and biofilm formation of Salmonella spp. in high and low concentrations of catfish mucus extract on different food-contact surfaces at 22 degrees C and 10 degrees C. The second objective of this study was to evaluate the efficacy of disinfectants at recommended concentrations and contact times for removing Salmonella biofilms cells on a stainless steel surface containing catfish mucus extract. Growth and biofilm formation of all Salmonella strains increased with higher concentrations of catfish mucus extract at both 10 degrees C and 22 degrees C. In 15 MUg/ml of catfish mucus extract inoculated with 3 log CFU/ml, the biofilm levels of Salmonella on stainless steel surface reached to 3.5 log CFU/cm2 at 10 degrees C or 5.5 log CFU/cm2 at 22 degrees C in 7 days. In 375 MUg/ml of catfish mucus extract inoculated with 3 log CFU/ml, the biofilm levels of Salmonella on the stainless steel surface reached 4.5 log CFU/cm2 at 10 degrees C and 6.5 log CFU/cm2 at 22 degrees C in 7 days. No differences were observed between Salmonella strains tested for biofilm formation in catfish mucus extract on the stainless steel surface. The biofilm formation by Salmonella Blockley (7175) in catfish mucus extract was less (P < 0.05) on buna-N rubber when compared to stainless steel, polyethylene and polyurethane surfaces. Salmonella biofilm cells were not detectable on the stainless steel surface after treatment with a mixture of disinfectants but were still present when single compound disinfectants were used. PMID- 29173626 TI - Microbial dynamics during production of lesser mealworms (Alphitobius diaperinus) for human consumption at industrial scale. AB - In this study, the microbial dynamics during an industrial production cyle of lesser mealworms (Alphitobius diaperinus), sold for human consumption, were characterised. The microbial numbers as well as the microbial diversity were generally higher for the substrate, existing of remaining feed, faeces and exuviae, than for the larvae. Most of the species-level operational taxonomic units, identified using Illumina MiSeq sequencing, that were present in the feed were also detected in the larvae and vice versa. However, bacterial diversity decreased in the larvae during rearing. These results suggested that the feed is an important determinant of the insect bacterial community, but that some bacterial species show a competitive advantage inside the insect gut and become dominant. A blanching treatment of the larvae after harvest reduced most microbial counts, but the number of aerobic endospores remained at 4.0 log cfu/g. Whereas food pathogens Salmonella spp., Listeria monocytogenes, Bacillus cereus or coagulase-positive staphylococci were not detected in our study, fungal isolates corresponding to the genera Aspergillus and Fusarium were recovered. Therefore, it cannot be excluded that mycotoxins were present. The results of this study contribute to a better understanding of the microbial dynamics and food safety aspects during the production of edible insects. PMID- 29173627 TI - Correlation between slaughter practices and the distribution of Salmonella and hygiene indicator bacteria on pig carcasses during slaughter. AB - This study investigated the distribution of hygiene indicator bacteria and Salmonella on pig carcasses. Moreover, the relation between hygiene indicator counts and Salmonella presence as well as associations between specific slaughter practices and carcass contamination were determined for each carcass area. Seven Belgian pig slaughterhouses were visited three times to swab five randomly selected carcasses at nine different areas, after evisceration and trimming. Information about slaughter practices was collected using a questionaire. In all samples, the E. coli and Salmonella presence was analyzed and Enterobacteriaceae and total aerobic bacteria were quantified. Average total aerobic counts ranged from 3.1 (loin, pelvic duct, ham) to 4.4 log10 CFU/cm2 (foreleg). Median Enterobacteriaceae numbers varied between 0.4 (ham) an 1.8 log10 CFU/cm2 (foreleg). E. coli and Salmonella presence ranged from 15% (elbow) to 89% (foreleg) and 5% (elbow) to 38% (foreleg), respectively. Positive relations were found between hygiene indicator counts and Salmonella presence at the head, sternum, loin and throat. Several slaughter practices, such as splitting the head and incising tonsils, were associated with higher levels of hygiene indicator bacteria and Salmonella. These findings can be used to educate slaughterhouse personnel and estimate the public health risk involved in consumption of different pork cuts. PMID- 29173628 TI - Survival of Escherichia coli O157:H7 during the manufacture and ripening of Cacioricotta goat cheese. AB - The aim of this study was to assess the growth and survival of Escherichia coli O157:H7 during the manufacturing and ripening of Cacioricotta goat cheese. Goat milk was artificially contaminated with E. coli O157:H7 and the bacterial load was monitored from production up to 90 days of ripening. Goat milk was inoculated with 102 cfu ml-1 of E. coli O157:H7 and the bacterial count of the curd at time zero was 2.31 log10 cfu g-1. During the first day of ripening, the bacterial load has increased to 5.73 log10 cfu g-1 to more than 6.20 log10 cfu g-1 during the first week. The bacterial load remained constant up to 28 days and then slightly decreased until the end of ripening, with values of aw and pH of 0.88 and 5.41 respectively. The results of this study highlighted that E. coli O157:H7 is able to survive the manufacturing process and they suggest that the 90-day period of ripening alone is insufficient to remove E. coli O157:H7 in contaminated Cacioricotta goat cheese. Moreover, these results support the assumption that the presence of a low contamination of milk with E. coli O157:H7 could represent a potential source of infection and a threat to consumers. PMID- 29173629 TI - Hydrogen sulfide synthesis in native Saccharomyces cerevisiae strains during alcoholic fermentations. AB - In order to diminish the undesirable impact of hydrogen sulfide (H2S) on wine, H2S synthesis was evaluated at phenotypic and transcriptional levels in 16 strains of Saccharomyces cerevisiae, which comprised 12 natural isolates, three commercial strains, and one laboratory heterozygote. Strain-dependent and multi gene participation traits were evident, and high gene activity did not necessarily elevated H2S levels. When the variation of gene expression was analyzed between fermentation stages in each strain, similarities among some strains related to H2S formation. UCD522 and seven strains with low H2S production were grouped together based on cluster analysis and fold-change analysis. They displayed a negative relationship between activity of MET17, HOM2, SER33 and CYS4 and H2S formation, suggesting the role of biosynthesis of sulfur containing amino acids. In the CECLFE1225, CECLFE1226 and UCD819 strains, transcriptional variation in MET3, MET5 and MET10 might account for the changes in H2S amount. High levels of HOM2 and SER33 expression were implicated with the H2S phenotype of CECGM1 (H2S-free strain). MET1 may be a key gene in sulfide biosynthesis owing to its involvement in almost all strains. This study furthers the understanding of H2S formation in different S. cerevisiae strains and the industrial application of natural isolates. PMID- 29173630 TI - Aroma profiling of an aerated fermentation of natural grape must with selected yeast strains at pilot scale. AB - The use of non-Saccharomyces strains in aerated conditions has proven effective for alcohol content reduction in wine during lab-scale fermentation. The process has been scaled up to 20 L batches, in order to produce lower alcohol wines amenable to sensory analysis. Sequential instead of simultaneous inoculation was chosen to prevent oxygen exposure of Saccharomyces cerevisiae during fermentation, since previous results indicated that this would result in increased acetic acid production. In addition, an adaptation step was included to facilitate non-Saccharomyces implantation in natural must. Wines elaborated with Torulaspora delbrueckii or Metschnikowia pulcherrima in aerated conditions contained less alcohol than control wine (S. cerevisiae, non-aerated). Sensory and aroma analysis revealed that the quality of mixed fermentations was affected by the high levels of some yeast amino acid related byproducts, which suggests that further progress requires a careful selection of non-Saccharomyces strains and the use of specific N-nutrients. PMID- 29173631 TI - The microbiota of eight species of dehydrated edible seaweeds from North West Spain. AB - The microbiota of eight species (Chondrus crispus, Himanthalia elongata, Laminaria ochroleuca, Palmaria palmata, Porphyra umbilicalis, Saccharina latissima, Ulva lactuca and Undaria pinnatifida) of edible seaweeds collected in North West Spain, marketed as dehydrated product, was quantitatively determined on nine solid media. Representative colonies were selected from solid culture media. The isolated microorganisms were identified by means of morphological characteristics, 16S rDNA sequencing and biochemical tests. U. pinnatifida was the seaweed species showing the most abundant microbial population, with counts on Marine agar up to 7.7 log cfu/g in individual samples and 5.0 log cfu/g as the mean value, and counts of coliforms up to 4.6 log cfu/g in individual samples and 2.4 log cfu/g as the mean value. The 225 identified bacterial isolates belonged to 11 families, 27 genera and 56 species. Bacillaceae was the family accounting for the highest number of isolates (111) followed by Enterobacteriaceae (60), Bacillales Family XII Incertae Sedis (20), Planococcaceae (11), Moraxellaceae (7), Paenibacillaceae (5) and Pseudomonadaceae (5). Bacterial species showing the highest occurrence in dehydrated seaweeds were Bacillus megaterium, B. licheniformis, Pantoea sp. and termoresistant Pantoea sp. Four of the Bacillus species isolated from dehydrated seaweeds (B. cereus, B. licheniformis, B. pumilus and B. subtilis) are among those containing strains considered to be foodborne pathogens and nine of the isolated non-Bacillales bacterial species have been reported to contain human opportunistic pathogenic strains. PMID- 29173632 TI - Microbiological, chemical and sensory spoilage analysis of raw Atlantic cod (Gadus morhua) stored under modified atmospheres. AB - During fish spoilage, microbial metabolism leads to the production of volatile organic compounds (VOCs), characteristic off-odors and eventual consumer rejection. The aim of the present study was to contribute to the development of intelligent packaging technologies by identifying and quantifying VOCs that indicate spoilage of raw Atlantic cod (Gadus morhua) under atmospheres (%v/v CO2/O2/N2) 60/40/0, 60/5/35 and air. Spoilage was examined by microbiological, chemical and sensory analyses over storage time at 4 or 8 degrees C. Selected ion flow-tube mass spectrometry (SIFT-MS) was used for quantifying selected VOCs and amplicon sequencing of the 16S rRNA gene was used for the characterization of the cod microbiota. OTUs classified within the Photobacterium genus increased in relative abundance over time under all storage conditions, suggesting that Photobacterium contributed to spoilage and VOC production. The onset of exponential VOC concentration increase and sensory rejection occurred at high total plate counts (7-7.5 log). Monitoring of early spoilage thus calls for sensitivity for low VOC concentrations. PMID- 29173633 TI - Virgin olive oil yeasts: A review. AB - This review summarizes current knowledge on virgin olive oil yeasts. Newly produced olive oil contains solid particles and micro drops of vegetation water in which yeasts reproduce to become the typical microbiota of olive oil. To date, about seventeen yeast species have been isolated from different types of olive oils and their by-products, of which six species have been identified as new species. Certain yeast species contribute greatly to improving the sensorial characteristics of the newly produced olive oil, whereas other species are considered harmful as they can damage the oil quality through the production of unpleasant flavors and triacylglycerol hydrolysis. Studies carried out in certain yeast strains have demonstrated the presence of defects in olive oil treated with Candida adriatica, Nakazawaea wickerhamii and Candida diddensiae specific strains, while other olive oil samples treated with other Candida diddensiae strains were defect-free after four months of storage and categorized as extra virgin. A new acetic acid producing yeast species, namely, Brettanomyces acidodurans sp. nov., which was recently isolated from olive oil, could be implicated in the wine-vinegary defect of the product. Other aspects related to the activity of the lipase-producing yeasts and the survival of the yeast species in the flavored olive oils are also discussed. PMID- 29173634 TI - Influence of surface polysaccharides of Escherichia coli O157:H7 on plant defense response and survival of the human enteric pathogen on Arabidopsis thaliana and lettuce (Lactuca sativa). AB - This study aimed to determine the influence of bacterial surface polysaccharides (cellulose, colanic acid, and lipopolysaccharide; LPS) on the colonization or survival of Escherichia coli O157:H7 on plants and the plant defense response. Survival of E. coli O157:H7 were evaluated on Arabidopsis thaliana and romaine lettuce as a model plant and an edible crop (leafy vegetable), respectively. The population of the wild-type strain of E. coli O157:H7 on Arabidopsis plants and lettuce was significantly (P < 0.05) greater compared with the colanic acid deficient and LPS-truncated mutants on day 1 and day 5 post-inoculation. This result indicates that colanic acid and LPS structures may contribute to the ability of bacterial survival or persistence on plants. The wild-type strain of E. coli O157:H7 produced approximately twice the amount (P < 0.05) of capsular polysaccharide (CPS) than the colanic acid and LPS-truncated mutants. The significantly lower production of CPS was associated with significantly greater (2-fold) expression of pathogenesis-related gene (PR1) compared with the wild type and cellulose-deficient mutant (P < 0.05). Collectively, the results of this study may suggest that specific surface polysaccharides of E. coli O157:H7 differentially induce the plant defense response, consequently affecting the survival of the human pathogen on plants. The survival and persistence of E. coli O157:H7 was similar on Arabidopsis and lettuce regardless of day post inoculation. PMID- 29173635 TI - Appropriate vacuolar acidification in Saccharomyces cerevisiae is associated with efficient high sugar fermentation. AB - Vacuolar acidification serves as a homeostatic mechanism to regulate intracellular pH, ion and chemical balance, as well as trafficking and recycling of proteins and nutrients, critical for normal cellular function. This study reports on the importance of vacuole acidification during wine-like fermentation. Ninety-three mutants (homozygous deletions in lab yeast strain, BY4743), which result in protracted fermentation when grown in a chemically defined grape juice with 200 g L-1 sugar (pH 3.5), were examined to determine whether fermentation protraction was in part due to a dysfunction in vacuolar acidification (VA) during the early stages of fermentation, and whether VA was responsive to the initial sugar concentration in the medium. Cells after 24 h growth were dual labelled with propidium iodide and vacuolar specific probe 6-carboxyfluorescein diacetate (6-CFDA) and examined with a FACS analyser for viability and impaired VA, respectively. Twenty mutants showed a greater than two-fold increase in fluorescence intensity; the experimental indicator for vacuolar dysfunction; 10 of which have not been previously annotated to this process. With the exception of Deltahog1, Deltapbs2 and Deltavph1 mutants, where dysfunction was directly related to osmolality; the remainder exhibited increased CF-fluorescence, independent of sugar concentration at 20 g L-1 or 200 g L-1. These findings offer insight to the importance of VA to cell growth in high sugar media. PMID- 29173636 TI - Development of a PCR-RFLP method based on the transcription elongation factor 1 alpha gene to differentiate Fusarium graminearum from other species within the Fusarium graminearum species complex. AB - Fusarium head blight (FHB) is a destructive disease of cereals crops worldwide and a major food safety concern due to grain contamination with trichothecenes and other mycotoxins. Fusarium graminearum, a member of the Fusarium graminearum species complex (FGSC) is the dominant FHB pathogen in many parts of the world. However, a number of other Fusarium species, including other members of the FGSC, may also be present for example in Argentina, New Zealand, Ethiopia, Nepal, Unites States in cereals such as wheat and barley. Proper species identification is critical to research aimed at improving disease and mycotoxin control programs. Identification of Fusarium species is are often unreliable by traditional, as many species are morphologically cryptic. DNA sequence-based methods offer a reliable means of species identification, but can be expensive when applied to the analyses of population samples. To facilitate identification of the major causative agent of FHB, this work describes an easy and inexpensive method to differentiate F. graminearum from the remaining species within the FGSC and from the other common Fusarium species causing FHB in cereals. The developed method is based on a PCR-RFLP of the transcription elongation factor (TEF 1 alpha) gene using the restriction enzyme BsaHI. PMID- 29173638 TI - Detection and identification of Penicillium spp. in a frozen chicken nuggets production facility. AB - Frozen chicken nuggets can be stored over a long period, during which time they may be exposed to temperature abuse conditions leading to spoilage by psychrophilic filamentous fungi. The purpose of this study was to investigate the main sources of chicken nugget spoilage. Mycological analyses were performed using raw materials and products from each stage of processing, as well as from the industry's indoor air environment. The species were identified through observation of macroscopic and microscopic characteristics of isolates. The powder coating of samples showed counts between 101 and 104 CFU/g, predominantly of the species Penicillium polonicum, Aspergillus flavus, Aspergillus candidus, Aspergillus (Eurotium) amstelodami and Penicillium citrinum. During chicken nugget processing, a reduction in fungal counts to 101 CFU/g was observed, with P. polonicum as the most dominant species present. Penicillium glabrum was the only species isolated from the final product analyzed (10%). Additionally, it was also the predominant species in the factory's air environment. According to the results, two possible sources of contamination of frozen chicken nuggets were detected, one from the lack of quality of the powder coatings used and another from the lack of clean air from the factory environment between the stages of baking and packaging. PMID- 29173637 TI - Screening of adjunct cultures and their application in ester formation in Camembert-type cheese. AB - The ethanol content and esterase and alcohol acyltransferase activities are the limiting factors in the synthesis of ethyl esters in Camembert-type cheeses. This study aimed to investigate the effects of alcohol, esterase and alcohol acyltransferase activities on ethyl ester formation in Camembert-type cheeses. Five experimental cheeses were prepared with three adjunct cultures with different enzyme activities and two levels of ethanol content (400 or 800 MUg/g). The cheeses were aged for 4 weeks and analysed weekly for basic physicochemical, textural, volatile and sensory properties. The results showed that both the enzyme activity and ethanol content were limiting factors in the synthesis of ethyl esters in the Camembert-type cheeses. Variation in the esterase synthesis activity was observed among lactic acid bacteria, and the starter culture Lactococcus lactis MA 14 LYO distinguished itself through its high acidifying and esterase hydrolysis abilities. The addition of CCFM 12, a lactic acid bacteria strain with high esterase and alcohol acyltransferase activity, along with 400 or 800 MUg/g of ethanol, notably enhanced the generation of ethyl esters and the corresponding fruity flavour, without causing dramatic changes in the basic physicochemical indices and microbial profile. In addition, cohesiveness was influenced by the addition of 400 and 800 MUg/g of ethanol, and more resilience with 800 MUg/g of ethanol had been found. The results showed that the addition of CCFM12 with 400 and 800 MUg/g of ethanol may be applied in the production of Camembert cheese to enhance its fruity flavour. PMID- 29173639 TI - Escherichia coli and Cronobacter sakazakii in 'Tommy Atkins' minimally processed mangos: Survival, growth and effect of UV-C and electrolyzed water. AB - These studies were aimed at assessing the growing capacity of Escherichia coli and Cronobacter sakazakii and the effectiveness of Ultraviolet-C (UV-C) radiation, acidic electrolyzed (AEW) and neutral electrolyzed (NEW) waters in the inhibition of these bacteria on minimally processed 'Tommy Atkins' mangoes (MPM). The fruits were contaminated by dip inoculation and kept 10 days at 4, 8, 12 and 20 degrees C while enumerating bacteria. Contaminated mangoes were disinfected using UV-C (2.5, 5, 7.5 and 10 kJ/m2), AEW, NEW and sodium hypochlorite (SH) and the microorganisms were monitored. None of the enterobacteria grew at 4, 8 and 12 degrees C regardless of having persisted during the 10-day period. At 20 degrees C, E. coli and C. sakazakii grew, after adaption phases of 48 h and 24 h, to values of 8.7 and 8.5 log cfu/g at day eight, respectively. E. coli showed the highest reduction counts on the MPM washed with NEW and SH (2.2 log cfu/g). UV-C was more effective in reducing C. sakazakii (2.4-2.6 log cfu/g), when compared to AEW, NEW and SH (1.2-1.8 log cfu/g). The efficacy of decontamination technologies depends on microorganisms, highlighting the importance of preventing contamination at the primary production and of combining different methods to increase the safety of fresh-cut fruits. PMID- 29173640 TI - Effect of high pressure processing on the survival of Salmonella Enteritidis and shelf-life of chicken fillets. AB - High pressure processing (HPP) is a preservation technology alternative to heat treatment that is mild for food, but effectively inactivates the spoilage microbiota and foodborne pathogens of several foods. The purpose of the current study was to evaluate the effect of HPP on Salmonella ser. Enteritidis, indigenous microbiota and shelf-life of chicken fillets. Chicken fillets were inoculated with S. Enteritidis at three different initial inocula (3, 5, 7 log CFU/g), packed under vacuum, treated or not with HPP (500 MPa/10 min) and stored at 4 and 12 degrees C. Total viable counts, S. Enteritidis, pseudomonads, Brochothrix thermosphacta, lactic acid bacteria, Enterobacteriaceae and yeasts/molds populations were determined in parallel with sensory analysis of non inoculated samples. The HPP resulted in the reduction of the pathogen population below the detection limit of the enumeration method (0.48 log CFU/g), irrespective of the inoculum. During the shelf life of the HPP samples, the pathogens population remained below or near the detection limit of the enumeration method at both temperatures, except from the high inoculum case that an increase was observed at 12 degrees C. At the low inoculum level, the pathogen could not be detected with the enrichment method after the first storage days (2nd day for 4 degrees C and 0 day for 12 degrees C). The survival of Salmonella strains was assessed by pulsed field gel electrophoresis and it was shown that the survival of the different strains depended on the inoculum and storage temperature. Regarding the indigenous microbiota, Br. thermosphacta was reported for the first time to be the main spoilage microorganism that survived and dominated after the HPP. From the results it was evident that, HPP may enhance the safety and increase the shelf life (6 at 4 degrees C and 2 days at 12 degrees C) of chicken meat. PMID- 29173641 TI - Microbial biodiversity of Sardinian oleic ecosystems. AB - The olives are rich in microorganisms that, during the extraction process may persist in the oils and can influence their physicochemical and sensory characteristics. In this work, and for the first time, we isolated and identified microbial species, yeast and bacteria, present during the production process in four Sardinian (Italy) oleic ecosystems. Among these varieties, we found that Nera di Gonnos was associated to the highest microbial biodiversity, which was followed by Bosana, Nocellara del Belice and Semidana. Among the different microbial species isolated, some are specific of olive ecological niches, such as Cryptococcus spp and Serratia spp; and others to olive oils such as Candida spp and Saccharomyces. Some other species identified in this work were not found before in oleic ecosystems. The enzymatic analyses of yeast and bacteria showed that they have good beta-glucosidase activity and yeast also showed good beta glucanase activity. The majority of bacteria presented lipolytic and catalase activities while in yeast were species-specific. Interestingly, yeast and bacteria isolates presented a high resistance to bile acid, and about 65% of the yeast were able to resist at pH 2.5 for 2 h. Finally, bacteria showed no biofilm activity compared to yeast. PMID- 29173642 TI - Diversity of bacterial communities in French chicken cuts stored under modified atmosphere packaging. AB - Poultry meat, the second most consumed meat in France, is commercialized mainly as portions of chicken cuts with various quality labels, stored under various modified atmosphere packaging (MAP), with shelf-life ranging from 9 to 17 days. We used 16S rDNA pyrosequencing to describe microbiota of chicken legs. Ten samples representing a wide diversity of labels and MAP available on the market were collected from local supermarkets and stored at 4 degrees C. Microbiota were collected, total DNA was extracted, and V1-V3 fragment of 16S rRNA genes were amplified and sequenced. For data analysis several pipelines were compared. The Qiime pipeline was chosen to cluster reads and we used a database previously developed for a meat and fish microbial ecology study. Variability between samples was observed and a listing of bacteria present on chicken meat was established. The structure of the bacterial communities were compared with traditional cultural methods and validated with quantitative real time PCR. Brochothrix thermosphacta, Pseudomonas sp., and Carnobacterium sp. were dominant and the nature of the gas used for packaging influenced the relative abundance of each suggesting a MAP gas composition dependent competition between these species. We also noticed that slaughterhouse environment may influence the nature of the contaminants. PMID- 29173643 TI - Primary souring: A novel bacteria-free method for sour beer production. AB - In the beverage fermentation industry, especially at the craft or micro level, there is a movement to incorporate as many local ingredients as possible to both capture terroir and stimulate local economies. In the case of craft beer, this has traditionally only encompassed locally sourced barley, hops, and other agricultural adjuncts. The identification and use of novel yeasts in brewing lags behind. We sought to bridge this gap by bio-prospecting for wild yeasts, with a focus on the American Midwest. We isolated 284 different strains from 54 species of yeast and have begun to determine their fermentation characteristics. During this work, we found several isolates of five species that produce lactic acid and ethanol during wort fermentation: Hanseniaspora vineae, Lachancea fermentati, Lachancea thermotolerans, Schizosaccharomyces japonicus, and Wickerhamomyces anomalus. Tested representatives of these species yielded excellent attenuation, lactic acid production, and sensory characteristics, positioning them as viable alternatives to lactic acid bacteria (LAB) for the production of sour beers. Indeed, we suggest a new LAB-free paradigm for sour beer production that we term "primary souring" because the lactic acid production and resultant pH decrease occurs during primary fermentation, as opposed to kettle souring or souring via mixed culture fermentation. PMID- 29173644 TI - Seafood pathogens and information on antimicrobial resistance: A review. AB - Seafood-borne diseases are a major public health hazard in the United States and worldwide. Per capita, seafood consumption has increased globally during recent decades. Seafood importation and domestic aquaculture farming has also increased. Moreover, several recent outbreaks of human gastroenteritis have been linked to the consumption of contaminated seafood. Investigation of seafood-borne illnesses caused by norovirus, and Vibrio, and other bacteria and viruses require a concrete knowledge about the pathogenicity and virulence properties of the etiologic agents. This review explores pathogens that have been associated with seafood and resulting outbreaks in the U.S. and other countries as well as the presence of antimicrobial resistance in the reviewed pathogens. The spectrum of such resistance is widening due to the overuse, misuse, and sub-therapeutic application of antimicrobials in humans and animals. PMID- 29173645 TI - Different Lactobacillus populations dominate in "Chorizo de Leon" manufacturing performed in different production plants. AB - "Chorizo de Leon" is a high-value Spanish dry fermented sausage traditionally manufactured without the use of starter cultures, owing to the activity of a house-specific autochthonous microbiota that naturally contaminates the meat from the environment, the equipment and the raw materials. Lactic acid bacteria (particularly Lactobacillus) and coagulase-negative cocci (mainly Staphylococcus) have been reported as the most important bacterial groups regarding the organoleptic and safety properties of the dry fermented sausages. In this study, samples from raw minced meat to final products were taken from five different producers and the microbial diversity was investigated by high-throughput sequencing of 16S rRNA gene amplicons. The diverse microbial composition observed during the first stages of "Chorizo de Leon" evolved during ripening to a microbiota mainly composed by Lactobacillus in the final product. Oligotyping performed on 16S rRNA gene sequences of Lactobacillus and Staphylococcus populations revealed sub-genus level diversity within the different manufacturers, likely responsible of the characteristic organoleptic properties of the products from different companies. PMID- 29173646 TI - Schisandra chinensis berry extract protects against steatosis by inhibiting histone acetylation in oleic acid-treated HepG2 cells and in the livers of diet induced obese mice. AB - We hypothesized that hepatic steatosis could be mitigated by the hypolipidemic activity of Schisandra chinensis berry ethanol extract (SCE) via the inhibition of histone acetyltransferase (HAT) activity. HepG2 cells treated with oleic acid (OA) in the presence of SCE exhibited reduced OA-induced lipid accumulation, which was likely mediated by reductions in SREBP-1c expression. SCE attenuated the acetylation of total lysine and H3K9 that was otherwise increased by OA. Male obese mice fed with either a low-fat diet or Western diet exhibited reduced body and liver weights when supplemented with 1% SCE. The SCE-mediated attenuation of hepatic lipid accumulation was accompanied by a decrease in the expression of lipogenic genes. SCE also attenuated the expression of acetylated lysine and non acetylated forms of H3K9 acetylation in the livers of these mice. Taken together, these results suggest that SCE has potential for further development as a novel therapeutic agent for the prevention of steatosis. PMID- 29173647 TI - Diet-induced obesity and weight loss alter bile acid concentrations and bile acid sensitive gene expression in insulin target tissues of C57BL/6J mice. AB - Bile acids (BAs) influence the metabolism of glucose, lipids, and energy expenditure. We hypothesized that BA concentrations and related gene expression would be altered in lean (low-fat diet fed; LFD) vs diet-induced obese (high-fat diet fed; HFD) groups of mice and that some detected changes would remain after weight loss in an HFD group switched to the LFD (SW). Taurine conjugates dominated the bile acid composition of the liver, epididymal white adipose tissue (eWAT), and hypothalamus, with the latter having lower levels (~95%, ~95%, and ~80%, respectively; P<.05). Plasma conjugated bile acids were elevated in the HFD relative to the LFD and SW animals. Total hepatic BA concentrations decreased in obese mice fed HFD, and levels returned to preobese levels in the SW group. Subtle changes in unconjugated bile acids were detected in the eWAT, hypothalamus, and muscle. Liver expression of a variety of enzymes involved in BA synthesis (eg, Cyp27a1, Acox2), BA transport (eg, Slc22a8), and BA-sensitive receptors (Fxr, Tgr5) were unchanged by HFD feeding but decreased with SW. Other hepatic enzymes were induced in the SW group (eg, Amacr and Bal). In eWAT, Cyp27a1 and Acox2 also declined in the SW group, whereas the HFD group showed reduced expression of BA transporters (eg, Abcc3), and changes in Fxr and Tgr5 were unclear. Therefore, although most detectable changes in BA metabolism associated with diet-induced obesity are reversed by diet-induced weight loss, some effects on BA composition, concentrations, and gene expression can persist after weight loss. PMID- 29173648 TI - In silico identification of milk antihypertensive di- and tripeptides involved in angiotensin I-converting enzyme inhibitory activity. AB - Identification of bioactive milk peptides could improve food technology through improved selection of food supplements with a focus on antihypertensive properties. We hypothesized that angiotensin I-converting enzyme (ACE) inhibitory activities of milk di- and tripeptides could be predicted using 3-dimensional quantitative structure activity relationship methods and that these activities could be explained through evaluation of structural features (hydrogen bond donor/acceptor, hydrophobic, steric, and electrostatic) that are responsible for this bioactivity. We aimed to build comparative molecular field analysis (CoMFA) models combined with in silico digestion to predict the peptide sequences released from enzymatic digestion and to evaluate peptides without experimental data. Furthermore, molecular docking simulation was performed with the aim to evaluate structural features. Molecular docking simulations revealed that the most potent inhibitory peptides contain hydrophobic amino acids that enter deep into the hydrophobic pocket of the ACE active site and make interactions with its residues. CoMFA results point out favorable steric interactions and electronegativity at the C-terminus of the milk dipeptides. The CoMFA model appears to favor electropositive amino acids at the second place in tripeptides and electronegative interaction with Tyr520. Furthermore, predicted values of ACE inhibitory activity of dipeptides obtained by peptide cutter are relatively high, which recommend them for application as functional food supplements and natural alternatives to ACE inhibitory drugs. This research suggests that obtained 3 dimensional quantitative structure activity relationship models are able to successfully identify milk-derived di- and tripeptides that have significant antihypertensive activity and provide information for screening and design of novel ACE inhibitors that could be used as supplements in human nutrition.

AB - Obesity is linked to several health complications, such as cardiovascular disease, insulin resistance, and hypertension. Dyslipidemia in obesity is one of the prime causes for health complications. We have previously shown that blue mussels (BM) are a rich source of omega (n)-3 polyunsaturated fatty acids (PUFA) and increase the mRNA expression of peroxisome-proliferator activated receptor and adiponectin, thereby inducing anti-obesity and insulin sensitizing effects in vitro. However, the in vivo effects of BM on obesity and metabolic regulation are not known. We hypothesized that dietary intake of BM will prevent weight gain and improve lipid profile of C57BL/6 mice fed a high-fat diet (HFD). Mice were fed a HFD supplemented with 5% w/w BM (BM-HFD) for 4 weeks, and then switched to a HFD for 4 weeks. Mice fed a BM-HFD showed significantly lower body weight gain and abdominal fat, compared to the HFD. Furthermore, a BM-HFD significantly reduced plasma and hepatic total and low-density lipoprotein (LDL)-cholesterol, compared to HFD. The decrease in cholesterol levels coincided with inhibition of hepatic sterol regulatory element-binding protein-2 and HMG-CoA reductase mRNA expression, and an increase in LDL-receptor gene expression in the BM-HFD group, compared to the HFD group. In conclusion, our findings have established that BM reduces body weight gain in mice. BM may have potential to lower cholesterol levels by inhibiting cholesterol synthesis, thereby protecting against obesity and perhaps heart disease. PMID- 29173650 TI - Evidence for the effectiveness of pomegranate supplementation for blood pressure management is weak: A systematic review of randomized clinical trials. AB - Hypertension is one of the most important preventable causes of premature death. Studies have been conducted assessing the impact of pomegranate on blood pressure, with varying results. The aim of this review was to critically appraise and evaluate the effect of pomegranate on blood pressure in adults, using evidence from randomized clinical trials (RCTs). We conducted electronic searches in Medline, Embase, Amed, and The Cochrane Library, and included RCTs assessing the effectiveness of pomegranate on blood pressure. We assessed the reporting quality using the Cochrane criteria. We included 8 RCTs comprising 619 participants. The studies varied in their reporting quality, and compared pomegranate juice or capsules with a control. Two studies reported significant reductions in systolic blood pressure favoring pomegranate: p = .002 and p < .001 respectively; 3 studies reported no significant differences between groups; and 3 studies failed to report between-group differences. Two studies reported significant reductions in diastolic blood pressure favoring pomegranate: p = .038, p < .001, respectively; 4 studies reported no significant between-group differences; and 2 studies did not report between group differences. No adverse events were observed. The limited evidence from clinical trials to date fails to convincingly show a beneficial effect of pomegranate on blood pressure. We have identified evidence gaps and highlight areas for future research to be conducted, including performing studies of high quality and longer duration. PMID- 29173651 TI - Foreword.

PMID- 29173655 TI - Management of Well-differentiated Gastroenteropancreatic Neuroendocrine Tumors (GEPNETs): A Review. AB - PURPOSE: Neuroendocrine tumors (NETs) are heterogeneous tumors that arise from the neuroendocrine cells of the digestive tract and other organs, such as the lung, ovary, and thyroid glands. They can be well differentiated or poorly differentiated, and management of these tumors differs for each histologic subtype. We have performed a review of NETs and focused on management of well differentiated gastroenteropancreatic neuroendocrine tumors (GEPNETs) and carcinoid syndrome. METHODS: A PubMed search was performed to obtain articles on the management of well-differentiated NETs. Using the key words neuroendocrine tumors, carcinoid, pNET, octreotide, somatostatin analogues, and radiolabeled therapy, we reviewed Phase II and III trials that were published over the past 30 years. We also reviewed guidelines from the European Neuroendocrine Tumor Society, North America Neuroendocrine Tumor Society, and National Comprehensive Cancer Network in our search. FINDINGS: NETs are usually slow-growing tumors that remain asymptomatic for a long duration and can be either nonfunctioning or functioning. Surgical resection is recommended for locoregional disease, impending obstruction, symptom control, and advanced disease. Nonsurgical treatment options include somatostatin analogues (SSAs), multikinase inhibitors, targeted therapy, chemotherapy, and radiolabeled SSAs. Carcinoid syndrome is mainly treated with SSAs. IMPLICATIONS: Although GEPNETs are slow-growing tumors, most patients are diagnosed with metastatic disease, and therefore it is important that the management of each patient be discussed in a multidisciplinary setting to optimize the treatment strategy. Patients should be considered for clinical trials and refractory cases referred to a specialty center. PMID- 29173656 TI - Cervical Epidural Steroid Injection: Techniques and Evidence. AB - Cervical epidural steroid injections are a common treatment of cervical radicular pain. Important safety considerations include attention to the possibility of spinal cord infarction and spinal epidural hematoma. When appropriate, radiographic, technical, and pharmacologic principals are used, these procedures are relatively safe. Cervical epidural steroid injections are effective for the short-term treatment of radicular pain. More rigorously designed clinical outcomes studies of both cervical interlaminar and transforaminal epidural steroid injections are needed. PMID- 29173657 TI - Sonographic Guide for Botulinum Toxin Injections of the Neck Muscles in Cervical Dystonia. AB - Intramuscular botulinum toxin (BoTX) injection is the first-line treatment of cervical dystonia. Poor treatment outcomes and some side effects, however, have been reported after BoTX applications. One of the most important reasons is incorrect localization of the needle during toxin injections. Without imaging, it is impossible to verify precise needle positioning in the proper muscle. Ultrasound has been recommended because of its high capability in illustrating most of the neck muscles. This review article discusses how ultrasound imaging can be used to scan/access neck muscles, mainly from the perspective of BoTX injections. PMID- 29173658 TI - Prolotherapy for the Thoracolumbar Myofascial System. AB - Prolotherapy has focused on entheses as a key source of chronic low back pain, even without clear diagnosis of enthesopathy. Treatment has traditionally been guided by anatomic knowledge and careful palpation. This article integrates ultrasonographic diagnosis of fascial injury with examination findings taught in traditional prolotherapy technique. Thoracolumbar fascial anatomy and biotensegrity theory are used to explain patient presentation and response to treatment at these pathologic findings. Detailed case reports provide proof of concept for the 60-year history of prolotherapy in the treatment of chronic low back pain. PMID- 29173659 TI - Radiofrequency Denervation of the Cervical and Lumbar Spine. AB - Facet or zygapophysial joint pain is commonly seen in the aging population. Interventional procedures, such as facet joint nerve blocks, facet intraarticular injections, and radiofrequency denervation, are used for the diagnosis and treatment of axial spinal chronic neck and low back pain. The focus of this article is to understand how radiofrequency denervation works in the cervical and lumbar spine and to be able to properly select appropriate patients who might benefit from this safe and effective procedure. PMID- 29173660 TI - Safety and Complications of Cervical Epidural Steroid Injections. AB - Serious neurologic complications following cervical transforaminal epidural steroid injections (CTFESI) and cervical interlaminar epidural steroid injections (CILESI) have been reported. For CILESI, this is caused by aberrant needle placement or space-occupying lesions, such as hematoma or abscess. For CTFESI, this is caused by embolic infarct when inadvertent intra-arterial injection of particulate steroids has occurred. Multiple safety techniques are used to mitigate the risk of these serious complications. The most common adverse events that occur following CTFESI or CILESI are procedural-related pain, steroid side effects, and vasovagal reactions, which are relatively minor and self-limited. PMID- 29173661 TI - Sacroiliac Joint Interventions. AB - Sacroiliac joint (SIJ) pain is an important cause of lower back problems. Multiple SIJ injection techniques have been proposed over the years to help in the diagnosis and treatment of this condition. However, the SIJ innervation is complex and variable, and truly intra-articular injections are sometimes difficult to obtain. Different sacroiliac joint injections have shown to provide pain relief in patients suffering this ailment. Various techniques for intraarticular injections, sacral branch blocks and radiofrequency ablation, both fluoroscopy guided and ultrasound guided are discussed in this paper. Less common techniques like prolotherapy, platelet rich plasma injections and botulism toxin injections are also discussed. PMID- 29173662 TI - Image and Contrast Flow Pattern Interpretation for Attempted Epidural Steroid Injections. AB - Fluoroscopically guided, contrast-enhanced epidural steroid injections (ESIs) are frequently performed for radicular symptoms. Interventionalists performing these procedures should have a thorough and detailed understanding of spinal anatomy to safely and effectively deliver the desired injectate to the targeted site. Being able to differentiate epidural from nonepidural contrast flow is vital as is recognizing flow to undesired locations. This article summarizes the characteristics that distinguish between ideal epidural flow patterns and nonideal subarachnoid, intradural, and other suboptimal contrast flow patterns. Recognizing these patterns is essential for safe and successful ESIs and to prevent avoidable complications. PMID- 29173663 TI - Lumbosacral Transitional Segments: An Interventional Spine Specialist's Practical Approach. AB - The presence of a lumbosacral transitional vertebrae (LSTV) should prompt a more detailed preprocedural evaluation of the vertebral column to accurately determine spinal levels. An LSTV should prompt the use of corroborating intraprocedural imaging to verify morphology. The most important factors in treating lumbosacral transitional segments are communication among treating physicians to ensure segmental enumeration consistency and associated appropriate patient treatment. PMID- 29173664 TI - Ultrasound for Lumbar Spinal Procedures. AB - Ultrasonography has become an increasingly valuable and promising tool for performing image-guided spine interventions. The increase in the use of ultrasound utilization has led to more studies evaluating ultrasound-guided interventional spine procedures in comparison to fluoroscopy and computed tomography. Several studies have investigated the use of ultrasound for lumbosacral pain management procedures with favorable outcomes. PMID- 29173665 TI - Peripheral Nerve Radiofrequency Neurotomy: Hip and Knee Joints. AB - Intra-articular hip and knee pain is a common cause of physical and psychosocial disability. Many conservative treatment options provide only short-term relief. Recent research studies have shown improvement in pain and function with minimal complications after radiofrequency neurotomy of the hip and the knee, especially in patients who have failed conservative treatment or are not surgical candidates. More quality research studies are needed to establish the efficacy and safety of these procedures in patients with refractory hip and knee pain. PMID- 29173666 TI - Lumbar Epidural Steroid Injections. AB - Lumbar epidural steroid injections under fluoroscopic guidance are used very commonly for the treatment of low back and lower extremity radicular pain. These procedures have been shown to be effective for pain relief in the short term and are relatively safe. The indications, evidence, and safety considerations for 2 different techniques-namely, interlaminar and transforaminal-are discussed. PMID- 29173667 TI - Ultrasound-Guided Interventions of the Cervical Spine and Nerves. AB - High-resolution ultrasound (US) enables prompt depiction of muscles, tendons, ligaments, and peripheral nerves. It seems to be the best imaging modality for guiding perineural injections. The most complicated neurovascular network of the musculoskeletal system surrounds the cervical spine; so injection to that region is never an easy task. This article elaborates the regional anatomy and the use of US scanning and guidance for cervical interventions; for example, cervical root, superficial cervical plexus, stellate ganglion, cervical medial branch, greater occipital nerve, and third occipital nerve. The article aims to lead readers to practice US-guided cervical injections precisely and safely. PMID- 29173668 TI - Foreword. PMID- 29173669 TI - Preface. PMID- 29173670 TI - Evaluation of Chest Pain and Acute Coronary Syndromes. AB - Chest pain is a common complaint in the emergency department, and it is the job of clinicians to rule out life-threatening diagnoses such as acute coronary syndrome. The history, physical examination, cardiac risk factors, electrocardiogram findings, and clinician judgment are often not enough to distinguish between causes of chest pain syndromes and to reliably rule out acute myocardial ischemia. New cardiac troponin assays, especially in conjunction with clinical decision algorithms, help clinicians rapidly exclude acute myocardial infarction. For further risk stratification, stress testing or coronary computed tomography angiography can be used in the emergency department. PMID- 29173671 TI - Acute Myopericardial Syndromes. AB - Acute myopericardial syndromes are common but can be challenging to manage and potentially have life-threatening complications. Careful clinical history, physical examination, electrocardiogram interpretation, and application of diagnostic criteria are needed to make an accurate diagnosis, exclude concomitant disease, and properly treat patients. Therapy for acute pericarditis should be guided per the underlying cause. For the most common causes, nonsteroidal antiinflammatory drugs or aspirin with the addition of colchicine remains the mainstay of therapy. Patients with hemodynamic compromise who are resistant to therapy or display high-risk features should prompt hospitalization and initiation of more aggressive and/or invasive therapy. PMID- 29173672 TI - Acute Valvular Heart Disease. AB - Valvular heart disease (VHD) is a common clinical entity. Recognition of decompensated VHD is crucial to instituting appropriate workup and management. Initial evaluation focuses on hemodynamics, peripheral perfusion, volume overload, and active myocardial ischemia. Initial therapy is targeted at improving hemodynamics, fluid status, and decreasing myocardial ischemia before intervention. Echocardiography can rapidly identify VHD etiology and severity along with physical examination findings. Owing to improved survival with cardiac surgery over the past several decades, prosthetic valve dysfunction should be recognized and initial treatment understood. Mechanical circulatory support is increasingly part of clinical practice in stabilizing patients with decompensated VHD. PMID- 29173673 TI - Ventricular Arrhythmias. AB - Ventricular tachycardia (VT) is the most common form of wide complex tachycardia and is associated with a high mortality rate. Electrocardiographic analysis remains paramount in diagnosis and helps to direct therapy. Antiarrhythmic agents, although effective in reducing arrhythmia burden, have never demonstrated a mortality benefit. The implantable cardioverter-defibrillator aids not only in the acute termination of ventricular arrhythmia, but provides a wealth of information for the long-term management of patients with VT. Contemporary treatment options such as catheter ablation are increasingly used and effective, but often remain imperfect, with recurrent VT being not uncommon. PMID- 29173674 TI - Evolving Electrocardiographic Indications for Emergent Reperfusion. AB - Chest pain or other symptoms concerning for acute coronary syndrome continues to remain a major reason for presentation to the emergency department. However, there is significant heterogeneity in the spectrum of risk severity of these patients. The electrocardiogram (ECG) remains a critically valuable tool in the physician's arsenal to diagnose patients and help with risk stratification. There are multiple high-risk ECG findings that are suggestive of adverse outcome and may benefit from rapid transfer for coronary angiography. This article reviews specific high-risk ECG patterns that may represent acute myocardial infarction or identify impending acute myocardial infarction that benefit from early diagnostic coronary angiography. PMID- 29173675 TI - Acute Management of Atrial Fibrillation: From Emergency Department to Cardiac Care Unit. AB - The prevalence of atrial fibrillation is increasing rapidly, resulting in more patients presenting for care in the emergency department and in-hospital settings. To reduce morbidity and mortality, and improve patient quality of life, clinicians working in these settings need to be both current and facile in their approach to management of these patients. Frequent updates to guideline recommendations (based on emerging research) make this challenging for practicing physicians. This article reviews the acute management of atrial fibrillation in the emergency and in-hospital settings, including practical approaches to rhythm and rate control, anticoagulation, and special situations, incorporating the most up-to-date guidelines. PMID- 29173676 TI - A New Face of Cardiac Emergencies: Human Immunodeficiency Virus-Related Cardiac Disease. AB - The human immunodeficiency virus epidemic is a major health challenge of the twenty-first century as the transition from infectious complications to noncommunicable disease becomes more evident. These patients may present to the emergency department with a variety of cardiovascular diseases, such as acute coronary syndromes, heart failure, pericardial disease, infective endocarditis, venothromboembolism, and other conditions. Increased awareness is needed among health care professionals to enhance adequate identification and promote prompt management of these patients. PMID- 29173677 TI - Cardiovascular Emergencies in Pregnancy. AB - Heart disease in pregnancy may manifest as acute coronary syndromes, decompensated valvular disease, and acute heart failure. These disease processes may represent progression of preexisting disease versus newly developed disease resulting from the physiologic changes of pregnancy. Early recognition of clinical presentations, judicious use of diagnostic studies, and multidisciplinary management of patient and fetal considerations can lead to optimal outcomes in this unique patient subset. PMID- 29173678 TI - Blunt Cardiac Trauma Review. AB - Patients suffering blunt cardiac trauma vary widely in the severity of their condition on presentation. Although some may present with mild sternal bruising, others may present with acute valvular rupture or malignant arrhythmia. Disposition for these patients ranges from discharge home to admission for urgent cardiac surgery. This article discusses some of the common types of blunt cardiac trauma and reviews the current literature and guidelines for their triage and initial management. PMID- 29173679 TI - Cardiac Biomarkers in Emergency Care. AB - This article critically reviews the latest evidence to guide the use of biomarkers for the diagnosis of acute coronary syndromes in practice. It shows how modern cardiac troponin assays can enable diagnoses to be ruled in or ruled out with a single blood test, with many more diagnoses confirmed or refuted in as little as 1 hour later. Finally, this article appraises the latest evidence for other cardiac biomarkers, such as heart-type fatty acid-binding protein and copeptin. PMID- 29173680 TI - Non-ST-Segment Acute Coronary Syndromes. AB - Acute coronary syndrome (ACS) represents an umbrella of ischemic myocardial disease and diagnoses encompassing unstable angina (UA), non-ST-elevation myocardial infarction (NSTEMI), and ST-elevation myocardial infarction (STEMI). UA and NSTEMI for all intents and purposes, share similar pathophysiology, but at increasing severity. This article focuses on the diagnosis, risk stratification, management, and strategies that impact outcomes in NSTEMI. PMID- 29173681 TI - Cardiogenic Shock. AB - Cardiogenic shock (CS) is a physiologic state in which cardiac pump function is inadequate to perfuse the tissues. If CS is not rapidly recognized and treated, tissue hypoperfusion can quickly lead to organ dysfunction and patient death. Evaluation of patients with suspected CS should include an electrocardiogram, chest radiograph, laboratory studies, and bedside echocardiogram. Initial resuscitation is directed toward restoring cardiac output and tissue perfusion. Mechanical circulatory support is indicated for patients with CS who do not respond to pharmacologic therapy. Ultimately, these patients should undergo emergent reperfusion therapy with either percutaneous coronary intervention or coronary artery bypass grafting. PMID- 29173682 TI - Acute Dyspnea and Decompensated Heart Failure. AB - The majority of patients hospitalized with acute heart failure (AHF) initially present to the emergency department (ED). Correct diagnosis followed by prompt treatment ensures optimal outcomes. Paradoxically, identification of high risk is not the unmet need, given nearly all ED AHF patients are hospitalized; rather, it is identification of low-risk. Currently, no risk-stratification instrument can be universally recommended to safely discharge ED patients. With the exception of diagnosis, management recommendations are largely expert opinion, informed by existing evidence and tradition. In the absence of robust evidence, we propose a framework for management to guide the busy clinician. PMID- 29173683 TI - Evolving Strategies in Cardiac Arrest Management. AB - Cardiac arrest is a leading cause of death in the United States, with a hospital discharge rate of approximately 10%. International resuscitation guidelines offer standardized cardiac arrest management approaches, but beyond the guidelines, are promising innovations to improve resuscitative care. Although clinical data do not yet support the routine use of mechanical chest compressions, corticosteroids, thrombolytics, and adjunctive ventilation devices during arrest, these therapies may have an important role in select patients. Extracorporeal membrane oxygenation during cardiopulmonary resuscitation is a promising advancement and may have survival benefit in select patients. The evidence for standard therapies and these innovations is discussed. PMID- 29173684 TI - Multidisciplinary Management of the Post-Cardiac Arrest Patient. AB - Cardiac arrest afflicts more than 300,000 persons annually in North America alone. Improving outcomes after cardiac arrest requires an integrated and multidisciplinary approach to postresuscitation intensive care and subsequent recovery. This article reviews components of injury within the post-cardiac arrest syndrome, the salient features of brain-oriented intensive care, best practices in neurologic prognostication, and a rational approach to emergency revascularization and hemodynamic support. PMID- 29173686 TI - Investigation of MEFV gene polymorphisms (G138G and A165A) in adult patients with familial Mediterranean fever. AB - AIM: Various mutations have been identified in the Mediterranean fever (MEFV) gene which is reported to be responsible from Familial Mediterranean fever (FMF). In our study, we aimed to determine the frequency of the MEFV mutations in our region and to investigate the impact of G138G (rs224224, c.414A>G) and A165A (rs224223, c.495C>A) gene polymorphisms on the clinical findings of the disease. METHODS: One hundred and sixteen patients diagnosed with FMF and 95 control subjects were included in this study. We used the DNA sequence analysis method to identify the most prevailing 10 mutations located in exon 2 and 10 of MEFV gene. RESULTS: As a result of the MEFV mutation analysis, the most common mutation was the M694V mutation allele with a frequency rate of 41.8%. When the patients group and control group were compared in terms of frequency of both polymorphic alleles (G polymorphic allele, observed in G138G and the A polymorphic allele, observed in A165A), the variation was observed to be statistically significant (p<0.001). It was found that the MEFV mutation types have no relation with clinical findings and amyloidosis (p>0.05). CONCLUSIONS: To our knowledge, our study is the first study in the Southern Marmara region that reports the frequency of MEFV mutations. Our findings imply that the polymorphisms of G138G and A165A may have an impact on progress of the disease. We think that more studies, having higher number of cases and investigating the polymorphisms of MEFV gene, are needed. PMID- 29173687 TI - Development of rheumatology training in Brazil: the option for a medical residency program. AB - OBJECTIVE: To describe the characteristics and progression of the supply of new rheumatologists in Brazil, from 2000 to 2015. METHODS: Consultations to databases and official documents of institutions related to training and certification of rheumatologists in Brazil took place. The data were compared, summarized and presented descriptively. RESULTS: From 2000 to 2015, Brazil qualified 1091 physicians as rheumatologists, of which 76.9% (n=839) completed a medical residency program in rheumatology (MRPR); the others (n=252) achieved this title without MRPR training. There was an expansion of MRPR positions. At the same time, there was a change in the profile of the newly qualified doctors. Early in the series, the fraction of new rheumatologists without MRPR, entering the market annually, was approaching 50%, dropping to about 15% in recent years. In 2015, Brazil offered 49 MRPR accredited programs, with 120 positions per year for access. There was an imbalance in the distribution of MRPR positions across the country, with a strong concentration in the southeast region, which in 2015 held 59.2% of the positions. Public institutions accounted for 94% (n=789) of graduates in MRPR during the study period, while still maintaining 93.3% (n=112) of seats for admission in 2015. CONCLUSIONS: In the last sixteen years, in parallel with the expansion of places of access, MRPR has established itself as the preferred route for rheumatology training in Brazil, mainly supported by public funds. Regional inequalities in the provision of MRPR positions still persist, as challenges that must be faced. PMID- 29173688 TI - Use of pamidronate for osteoporosis treatment in public health care in Brazil. AB - PURPOSE: The use of bisphosphonates for osteoporosis is effective in reducing the risk of fractures. However, oral formulations are sometimes not well tolerated or are contraindicated. Due to its availability in Brazilian public health system, pamidronate is frequently prescribed for osteoporosis, despite the lack of studies demonstrating its anti-fracture efficacy and the absence of FDA or EMEA approval for this purpose. The aim of this study was to evaluate the bone mineral density (BMD) response to pamidronate in a group of women with osteoporosis in a tertiary care hospital. PATIENTS AND METHODS: The medical records of women with osteoporosis who received pamidronate for up to two years of treatment were reviewed. Patients were stratified at high or intermediate risk of fracture. RESULTS: A total of 70 women were in treatment with pamidronate. Among them, 74% were at high risk of fracture. A significant gain in spine BMD after 24 months of treatment was observed (p=0.012). There was no difference between the groups of high and not high risk of fracture. At the femur, no significant increase in BMD was present, though, a strong negative correlation with high PTH levels (r=-0.61; p=0.003) was seen. In the multivariate analysis BMI at 12 months had impact in the response to the treatment. CONCLUSION: The intravenous pamidronate in a group of postmenopausal women with predominant high risk of fracture promoted an isolated gain in the spine BMD, even though, clinical randomized trials are needed to confirm its anti-fracture efficacy. PMID- 29173689 TI - Esophageal abnormalities in juvenile localized scleroderma: is it associated with other extracutaneous manifestations? AB - OBJECTIVE: To assess esophageal involvement (EI) in juvenile localized scleroderma (JLS) population and the possible association between this gastrointestinal manifestation and demographic data, clinical features, laboratory exams, treatments and outcomes. METHODS: For a period of 30 years, 5881 patients with rheumatic diseases were followed in our Pediatric Rheumatology Division. EI was defined by the presence of symptoms (solid/liquid dysphagia, heartburn, esophageal regurgitation, nausea/vomiting and epigastralgia) and confirmed by at least one EI exam abnormality: barium contrast radiography, upper gastrointestinal endoscopy and 24-hour esophageal pH-monitoring. RESULTS: JLS was observed in 56/5881 patients (0.9%), mainly linear morphea subtype. EI was observed in 23/56(41%) of JLS patients. Eight(35%) of 23 EI patients with JLS were symptomatic and presented heartburn(5/8), solid and liquid dysphagia(3/8), nausea and epigastralgia(1/8). The frequency of any cumulative extracutaneous manifestations (calcinosis, arthritis/arthralgia, central nervous system, interstitial pneumonitis, mesangial nephritis and/or arrhythmia) was significantly higher in JLS patients with EI compared to those without this complication (56% vs. 24%, p=0.024). No differences were evidenced in demographic data, JLS subtypes and in each extracutaneous manifestation in both groups (p>0.05). The frequency of methotrexate use was significantly higher in JLS patients with EI compared to those without (52% vs. 12%, p=0.002). Autoantibody profile (antinuclear antibodies, anti-SCL-70, rheumatoid factor, anticentromere, anti-cardiolipin, anti-Ro/SSA and anti-La/SSB) was similar in both groups (p>0.05). CONCLUSIONS: Our study demonstrated that EI was frequently observed in JLS patients, mainly in asymptomatic patients with linear subtype. EI occurred in JLS patients with other extracutaneous manifestations and required methotrexate therapy. PMID- 29173690 TI - Omega-3 fatty acids, inflammatory status and biochemical markers of patients with systemic lupus erythematosus: a pilot study. AB - BACKGROUND: Studies have shown that omega-3 fatty acids reduce the concentrations of eicosanoids, cytokines, chemokines, C-reactive protein (CRP) and other inflammatory mediators. OBJECTIVE: To investigate the effects of omega-3 fatty acids on circulating levels of inflammatory mediators and biochemical markers in women with systemic lupus erythematosus (SLE). METHODS: Experimental clinical study (clinical trial: NCT02524795); 49 women with SLE (ACR1982/1997) were randomized: 22 to the omega-3 group (daily intake of 1080mg EPA+200mg DHA, for 12 weeks) and 27 to the control group. The inflammatory mediators and biochemical markers at T0 and T1 in omega-3 group were compared using Wilcoxon test. U-Mann Whitney test was used to compare variations of measured variables [DeltaV=pre treatment (T0)-post-treatment (T1) concentrations] between groups. p<0.05 was considered significant. RESULTS: The median (interquartile range - IQR) of age was 37 (29-48) years old, of disease duration was 7 (4-13) years, and of SLEDAI 2K was 1 (0-2). The median (IQR) of variation in CRP levels between the two groups showed a decrease in omega-3 group while there was an increase in control group (p=0.008). The serum concentrations of IL-6 and IL-10, leptin and adiponectin did not change after a 12 week treatment. CONCLUSIONS: Supplementation with omega-3 had no impact on serum concentrations of IL-6, IL 10, leptin and adiponectin in women with SLE and low disease activity. There was a significant decrease of CRP levels as well as evidence that omega-3 may impact total and LDL-cholesterol. PMID- 29173691 TI - Clinical outcomes and survival in AA amyloidosis patients. AB - AIM: Amyloid A amyloidosis is a rare complication of chronic inflammatory conditions. Most patients with amyloid A amyloidosis present with nephropathy and it leads to renal failure and death. We studied clinical characteristics and survival in patients with amyloid A amyloidosis. METHODS: A total of 81 patients (51 males, 30 females) with renal biopsy proven amyloid A amyloidosis were analyzed retrospectively. The patients were divided into good and poor outcomes groups according to survival results. RESULTS: Most of the patients (55.6%) had nephrotic range proteinuria at diagnosis. Most frequent underlying disorders were familial Mediterranean fever (21.2%) and rheumatoid arthritis (10.6%) in the good outcome group and malignancy (20%) in the poor outcome group. Only diastolic blood pressure in the good outcome group and phosphorus level in the poor outcome group was higher. Serum creatinine levels increased after treatment in both groups, while proteinuria in the good outcome group decreased. Increase in serum creatinine and decrease in estimated glomerular filtration rate of the poor outcome group were more significant in the good outcome group. At the time of diagnosis 18.5% and 27.2% of all patients had advanced chronic kidney disease (stage 4 and 5, respectively). Median duration of renal survival was 65+/-3.54 months. Among all patients, 27.1% were started dialysis treatment during the follow-up period and 7.4% of all patients underwent kidney transplantation. Higher levels of systolic blood pressure [hazard ratios 1.03, 95% confidence interval: 1-1.06, p=0.036], serum creatinine (hazard ratios 1.25, 95% confidence interval: 1.07-1.46, p=0.006) and urinary protein excretion (hazard ratios 1.08, 95% confidence interval: 1.01-1.16, p=0.027) were predictors of end-stage renal disease. Median survival of patients with organ involvement was 50.3+/-16 months. CONCLUSION: Our study indicated that familial Mediterranean fever constituted a large proportion of cases and increased number of patients with idiopathic amyloid A amyloidosis. Additionally, it was observed that patient survival was not affected by different etiological causes in amyloid A amyloidosis.

AB - INTRODUCTION: Fatigue, anxiety and depression are very frequent symptoms in patients with rheumatoid arthritis (RA). GOALS: In this study we evaluated the influence of socioeconomic characteristics, therapy and comorbidities on the self reported high fatigue, anxiety and depression in patients with RA. METHOD: Multicenter cross-sectional study was performed in 22 health institutions in Serbia during the period from April-August 2014 in population of older RA patients. Self-reported patients health status was measured by: Fatigue Assessment Scale, Patient Health Questionnaire-9 and Generalized Anxiety Disorder 7. Treatment modalities were defined as: (1) non-steroidal anti-inflammatory drugs (NSAIDs) and/or analgesics and/or corticosteroids; (2) synthetic disease modifying antirheumatic drugs (DMARDs) alone or in combination with corticosteroids and/or NSAIDs and (3) any RA treatment which includes biologic DMARDs. RESULTS: There were significant predictors of high depression: synthetic DMARDs therapy in combination with corticosteroids and/or NSAIDs, physiotherapist self-payment, frequent taxi use, alternative treatment and employment status. The need for another person's assistance, supplemental calcium therapy and professional qualifications were the predictors of a high fatigue, whereas the age above 65 years had the protective effect on it. Anxiety was an independent high fatigue predictor. The predictors of a high anxiety were: gastroprotection with proton-pump inhibitors and patient occupation. CONCLUSION: Socioeconomic predictors of self-reported high depression, anxiety or fatigue are different for each of the mentioned outcomes, while accompanied with the basic RA treatment they exclusively explain a high depression. The anxiety, jointed with the socioeconomic variables and supplemental therapy, is a significant fatigue predictor in RA patients.

AB - Anti-tumor necrosis factor drugs are frequently preferred in the treatment of rheumatologic diseases and other inflammatory diseases. The development of myositis after using anti-tumor necrosis factor drugs is a rare clinical condition. Here we aimed to report cases who developed myositis after using anti tumor necrosis factor drugs and review the current literature. We report two cases of rheumatoid arthritis and a case of ankylosing spondylitis developed idiopathic inflammatory myopathy following anti-tumor necrosis factor therapy. In conclusion, myositis could develop during anti-tumor necrosis factor therapy, so these patients should be evaluated carefully initially for myositis and should be closely monitored due to the potential for developing myositis in treatment process. PMID- 29173694 TI - Cyclophosphamide administration routine in autoimmune rheumatic diseases: a review. AB - Cyclophosphamide is an alkylating agent widely used for the treatment of malignant neoplasia and which can be used in the treatment of multiple rheumatic diseases. Medication administration errors may lead to its reduced efficacy or increased drug toxicity. Many errors occur in the administration of injectable drugs. The present study aimed at structuring a routine for cyclophosphamide use, as well as creating a document with pharmacotherapeutic guidelines for the patient. The routine is schematized in three phases: pre-chemotherapy, administration of cyclophosphamide, and post-chemotherapy, taking into account the drugs to be administered before and after cyclophosphamide in order to prevent adverse effects, including nausea and hemorrhagic cystitis. Adverse reactions can alter laboratory tests; thus, this routine included clinical management for changes in white blood cells, platelets, neutrophils, and sodium, including cyclophosphamide dose adjustment in the case of kidney disease. Cyclophosphamide is responsible for other rare - but serious - side effects, for instance, hepatotoxicity, severe hyponatremia and heart failure. Other adverse reactions include hair loss, amenorrhea and menopause. In this routine, we also entered guidelines to post-chemotherapy patients. The compatibility of injectable drugs with the vehicle used has been described, as well as stability and infusion times. The routine aimed at the rational use of cyclophosphamide, with prevention of adverse events and relapse episodes, factors that may burden the health care system.

There have been suggestions about the nomenclature of systemic vasculitis. Important categories were added to the classification of vasculitis, and many changes were made for disease names in the second Chapel Hill Consensus Conference 2012, which were not included in the Chapel Hill Consensus Conference 1994. The new nomenclature was introduced instead of being referred to by many names such as Churg-Strauss and Wegener"s. New categories such as Behcet"s and Cogan etc. were also added. These people are honored by the classification. They contribute to science through their case studies, scientific articles, and observations. This article reviews only eponyms present in the current classification of vasculitis. The aim of this paper is to give information about scientists mentioned in the classification of vasculitis.

The current article reviews the core competencies and current trends associated with IPCP, including challenges faced by health care practitioners when working on interprofessional teams. Several conceptual frameworks and empirically supported interventions from the fields of organizational psychology and organization development are presented to assist health care professionals in transitioning their teams to a more interprofessionally collaborative, team-based model of practice.

Clinical practice guidelines set the collaborative prescriptive standards for the medical management of otitis media in children. Treatment of this condition does not end with the medical practitioner. There are far-reaching effects of otitis media and its sequelae that permeate every aspect of patients' lives including physiological, educational, and psychosocial. Therefore, a comprehensive interprofessional treatment plan must be designed taking into consideration best practices from a range of professions to maximize clinical outcomes, including the treating physician, speech-language pathologist, clinical audiologist, educational audiologist, and professionals in the educational setting. PMID- 29173712 TI - Using the International Classification of Functioning, Disability and Health Framework to Achieve Interprofessional Functional Outcomes for Young Children: A Speech-Language Pathology Perspective. AB - The International Classification of Functioning, Disability and Health (ICF) framework is an excellent tool to facilitate the writing of functional goals for children who exhibit communication disorders and other developmental problems that require services from professionals in multiple therapeutic areas. The holistic view of children provides each professional with an approach that integrates how one's specific health conditions and contextual factors influence a child's functioning and participation in daily activities. This allows the interprofessional team to view the child as a person, recognizing how one need influences another within his or her environment. PMID- 29173713 TI - Late Talkers: Why the Wait-and-See Approach Is Outdated. AB - From a speech-language pathology perspective, there is a gap in interprofessional education/practice (IPE/IPP) that leads to a wait-and-see approach with late talkers (LT). In line with the American Speech-Language-Hearing Association's Strategic Pathway to Excellence, this article attempts to bridge the gap, reexamining the panoptic view that most LT "catch up" to their peers. The LT who persist with language disorder should not be overlooked. Late talking can impact socialization and school readiness, and can place some toddlers at risk for life long disability. Each state's early intervention program has an established IPP infrastructure. Parent-implemented intervention addresses risks and maximizes protective factors.

AB - Practices in the neonatal intensive care unit (NICU) that reduce infant stress and respond to behavioral cues positively influence developmental outcomes. Proactive developmental surveillance and timely introduction of early intervention services improve outcomes for premature infants. A model that emphasizes infant development and a continuum of care beginning in the NICU with transition to outpatient monitoring and provision of early intervention services is hypothesized to support the most optimal outcomes for premature infants. PMID- 29173715 TI - Interprofessional Collaborative Practice in Early Intervention. AB - Professionals in pediatric practice encounter infants and toddlers with developmental delays, disabilities, or complex chronic health conditions eligible for Part C early intervention (EI) services. The most frequently identified concern by families is communication emphasizing the importance of the role of the speech language pathologist (SLP). This article provides a conceptual framework for SLP services in early intervention, based on the principles of interprofessional collaboration. The history of collaboration, EI, and the role of SLPs as members of the EI team are summarized. The competencies mandated for interprofessional education and practice are juxtaposed with the principles of EI and guidelines for SLPs.

PMID- 29173717 TI - The Future of Pediatric Speech-Language Pathology in a More Collaborative World. AB - Examining interprofessional practice through the lens of speech-language pathology identifies a number of challenges to and opportunities for interprofessional practice. While practitioners believe they practice interprofessionally, health services are often distributed across a network within which collaboration can falter. Certain professions, like speech-language pathology, are well-positioned to work across this network and improve care. Barriers to collaboration are interpersonal, structural, regulatory, and governmental. To enhance interprofessional practice, students should receive interprofessional education; practitioners should engage in interprofessional continuing education based on their practice environment; and leaders and researchers should identify frameworks to support better interprofessional practice.

CinC focuses on modification of the demands of an activity with guidance from a health care professional who coaches the family to increase their participation in everyday activities. An interprofessional team is key in this process. Working as a team and communicating effectively across professions supports the health professional who serves as the coach. Effective interprofessional team collaboration is possible; health professions share values for the delivery of the highest quality of care.

In healthy children who are developing and growing normally, feeding problems are usually not serious and can be managed conservatively by reassuring the family and providing them with anticipatory guidance and follow-up. A majority of serious childhood feeding problems occur in children who have other medical, developmental, or behavioral problems. These are best evaluated and treated by an interprofessional team who can identify and address issues in the medical and/or developmental history, problems with oral motor control and function, problems with swallowing, and behavioral and/or sensory issues that may interfere with normal feeding.

Delays or disruptions due to isolated expressive language delay, articulation errors, multiple sound production errors with motor planning deficits, or mixed expressive and receptive language delay, often bring widespread consequences. Physical anomalies, neurologic and genetic disorder, cognitive and intellectual disabilities, and emotional disturbances may affect speech and language development. Communication disorders may be misdiagnosed as intellectual impairment or autism. Interdisciplinary evaluation should include speech and language assessment, physical and neurologic status, cognitive and emotional profile, and family and social history.

PMID- 29173725 TI - Hyaluronan and Hyaluronan Fragments. AB - The glycosaminoglycan hyaluronan (HA) is a key component of the microenvironment surrounding cells. In healthy tissues, HA molecules have extremely high molecular mass and consequently large hydrodynamic volumes. Tethered to the cell surface by clustered receptor proteins, HA molecules crowd each other, as well as other macromolecular species. This leads to severe nonideality in physical properties of the biomatrix, because steric exclusion leads to an increase in effective concentration of the macromolecules. The excluded volume depends on both polymer concentration and hydrodynamic volume/molecular mass. The biomechanical properties of the extracellular matrix, tissue hydration, receptor clustering, and receptor-ligand interactions are strongly affected by the presence of HA and by its molecular mass. In inflammation, reactive oxygen and nitrogen species fragment the HA chains. Depending on the rate of chain degradation relative to the rates of new synthesis and removal of damaged chains, short fragments of the HA molecules can be present at significant levels. Not only are the physical properties of the extracellular matrix affected, but the HA fragments decluster their primary receptors and act as endogenous danger signals. Bioanalytical methods to isolate and quantify HA fragments have been developed to determine profiles of HA content and size in healthy and diseased biological fluids and tissues. These methods have potential use in medical diagnostic tests. Therapeutic agents that modulate signaling by HA fragments show promise in wound healing and tissue repair without fibrosis. PMID- 29173726 TI - The Synthesis and Biological Characterization of Acetal-Free Mimics of the Tumor Associated Carbohydrate Antigens. AB - Carcinomas express unique carbohydrates, known as tumor-associated carbohydrate antigens (TACAs), on their surface. These are potential targets for anticancer vaccines; however, to date, no such vaccine has reached the clinic. One factor that may complicate the success of this effort is the lability of the glycosidic bond. Acetal-free carbohydrates are analogues that lack the glycosidic linkage by replacing either the endo or exo oxygen with a methylene. This chapter summarizes the seminal syntheses of the mucin TACAs, provides an overview of common techniques for the synthesis of carbasugars and C-glycosides, reviews the syntheses published to date of acetal-free TACA analogues, and provides an overview of their observed biological activity. We conclude by offering a summation of the challenges remaining to the field biologically and the potential that acetal-free TACAs have of answering several basic questions in carbohydrate immunology. PMID- 29173727 TI - Application of Porous Materials to Carbohydrate Chemistry and Glycoscience. AB - There is a growing interest in using a range of porous materials to meet research needs in carbohydrate chemistry and glycoscience in general. Among the applications of porous materials reviewed in this chapter, enrichment of glycans from biological samples prior to separation and analysis by mass spectrometry is a major emphasis. Porous materials offer high surface area, adjustable pore sizes, and tunable surface chemistry for interacting with glycans, by boronate affinity, hydrophilic interactions, molecular imprinting, and polar interactions. Among the materials covered in this review are mesoporous silica and related materials, porous graphitic carbon, mesoporous carbon, porous polymers, and nanoporous gold. In some applications, glycans are enzymatically or chemically released from glycoproteins or glycopeptides, and the porous materials have the advantage of size selectivity admitting only the glycans into the pores and excluding proteins. Immobilization of lectins onto porous materials of suitable pore size allows for the use of lectin-carbohydrate interactions in capture or separation of glycoproteins. Porous material surfaces modified with carbohydrates can be used for the selective capture of lectins. Controlled release of therapeutics from porous materials mediated by glycans has been reported, and so has therapeutic targeting using carbohydrate-modified porous particles. Additional applications of porous materials in glycoscience include their use in the supported synthesis of oligosaccharides and in the development of biosensors for glycans.

AB - OBJECTIVE: To evaluate the efficacy and safety of lurasidone in children and adolescents with bipolar depression. METHOD: Patients 10 to 17 years old with a DSM-5 diagnosis of bipolar I depression were randomized to 6 weeks of double blind treatment with flexible doses of lurasidone 20 to 80 mg/day. The primary endpoint was change from baseline to week 6 in the Children's Depression Rating Scale-Revised (CDRS-R) total score, evaluated by a mixed-model repeated-measures analysis. RESULTS: A total of 347 patients were randomized and received at least 1 dose of lurasidone (n = 175; mean age 14.2 years; mean dose 33.6 mg/day) or placebo (n = 172; mean age 14.3 years). At week 6, treatment with lurasidone was associated with statistically significant improvement compared with placebo in CDRS-R total score (-21.0 versus -15.3; p < .0001; effect size 0.45). Lurasidone also was associated with statistically significant improvement in the Clinical Global Impression-Bipolar Severity depression score (key secondary measure) and in measures of anxiety, quality of life, and global functioning. Study completion rates were 92.0% in the lurasidone group and 89.7% in the placebo group; discontinuation rates due to adverse events were the same for the 2 groups (1.7%). The 2 most common adverse events on lurasidone were nausea and somnolence. Treatment with lurasidone was associated with few effects on weight and metabolic parameters. CONCLUSION: In this placebo-controlled study, monotherapy with lurasidone, in the dose range of 20 to 80 mg/day, significantly decreased depressive symptoms in children and adolescents with bipolar depression. Lurasidone was well tolerated, with minimal effects on weight and metabolic parameters.

PMID- 29173736 TI - Clinical Implications From the Treatment of Severe Childhood Aggression (TOSCA) Study: A Re-Analysis and Integration of Findings. AB - OBJECTIVE: The Treatment of Severe Childhood Aggression (TOSCA) project examined augmentation of stimulant treatment and parent training (PT) with risperidone for severe physical aggression. This article summarizes the clinical implications; reanalyzes the data to examine the utility of 4 criteria for deciding to augment; and presents a treatment algorithm. METHOD: The newly analyzed 4 criteria for augmenting after 3 weeks of stimulant and PT treatment consisted of not meeting a Clinical Global Impressions-Improvement (CGI-I) score of 1 and a normal score (<=15) on the Nisonger Child Behavior Rating Form Disruptive-Total (D-Total); a CGI-I score of 1 or 2 plus 25% improvement in D-Total score; a D-Total score no higher than 15; and a CGI-Severity score of 3 (mild) or better. Effect sizes were calculated. Prior TOSCA publications were reviewed for clinically relevant findings. RESULTS: All 4 criteria resulted in medium or better effect sizes (d = 0.59-0.72) when comparing risperidone with placebo. Providing risperidone to children who did not reach a CGI-I score of 1 plus a D-Total score no higher than 15 resulted in the greatest benefit. In addition, a review of clinically relevant data suggests that stimulant plus PT shows further improvement after 3 weeks even without augmentation. CONCLUSION: For those children who did not attain a CGI-I score of 1 and a D-total score no higher than 15, adding risperidone maximized the number of children benefitting from treatment and the average amount of benefit. Unless clinical circumstances dictate otherwise, practitioners should delay an antipsychotic drug for at least 1 month after the optimal stimulant dose is achieved and PT has commenced.

AB - OBJECTIVE: Although evidence-based treatments for pediatric obsessive-compulsive disorder (OCD) exist, many youth fail to respond, and interventions tailored to the needs of specific subsets of patients are lacking. This study examines the efficacy of a family intervention module designed for cases of OCD complicated by poor family functioning. METHOD: Participants were 62 youngsters aged 8 to 17 years (mean age = 12.71 years; 57% male; 65% white) with a primary diagnosis of OCD and at least 2 indicators of poor family functioning. They were randomized to receive 12 sessions of individual child cognitive-behavioral therapy (CBT) plus weekly parent psychoeducation and session review (standard treatment [ST]) or the same 12 child sessions plus 6 sessions of family therapy aimed at improving OCD related emotion regulation and problem solving (positive family interaction therapy [PFIT]). Blinded raters evaluated outcomes and tracked responders to 3 month follow-up. RESULTS: Compared to ST, PFIT demonstrated better overall response rates on the Clinician Global Impression-Improvement scale (CGI-I; 68% versus 40%, p = .03, phi = 0.28) and rates of remission (58% PFIT versus 27% ST, p = .01, phi = 0.32). PFIT also produced significantly greater reductions in functional impairment, symptom accommodation, and family conflict, and improvements in family cohesion. As expected, these shifts in family functioning constitute an important treatment mechanism, with changes in accommodation mediating treatment response. CONCLUSION: PFIT is efficacious for reducing OCD symptom severity and impairment and for improving family functioning. Findings are discussed in terms of personalized medicine and mechanisms of change in pediatric OCD treatment.

PMID- 29173738 TI - Therapist-Reported Features of Exposure Tasks That Predict Differential Treatment Outcomes for Youth With Anxiety. AB - OBJECTIVE: Exposure tasks are recognized widely as a key component of cognitive behavioral therapy (CBT) for child and adolescent anxiety. However, little research has examined specific exposure characteristics that predict outcomes for youth with anxiety and that may guide its application in therapy. METHOD: This study draws on a sample of 279 children and adolescents (48.4% male; 79.6% white) with a principal anxiety disorder who received 14 sessions of CBT, either alone or in combination with medication, through the Child/adolescent Anxiety Multimodal treatment Study (CAMS). The present study examines therapist-reported quantity, difficulty level, compliance, and mastery of exposure tasks as they related to CBT response (i.e., Clinical Global Impressions-Improvement ratings). Secondary treatment outcomes included reduction in anxiety symptom severity on the Pediatric Anxiety Rating Scale, global impairment measured via the Children's Global Assessment Scale, and parent-report of anxiety-specific functional impairment on the Child Anxiety Impairment Scale. RESULTS: Regression analyses indicated a dose-response relationship between therapist-reported quantity of exposure and independent evaluations of treatment outcome, with more time devoted to exposure linked to better outcomes. Similarly, greater time spent on more difficult (rather than mild or moderate) exposure tasks predicted better outcomes, as did therapist ratings of child compliance and mastery. CONCLUSION: The present findings highlight the importance of challenging children and adolescents with difficult exposure tasks and of collaborating to ensure compliance and mastery. PMID- 29173739 TI - A Two-Week Psychosocial Intervention Reduces Future Aggression and Incarceration in Clinically Aggressive Juvenile Offenders. AB - OBJECTIVE: There is a largely unmet need for evidence-based interventions that reduce future aggression and incarceration in clinically aggressive juvenile offenders serving probation. We addressed this gap using a group randomized controlled trial. Offenders both with and without clinical aggression were included, enabling comparison of intervention effects. METHOD: Juveniles 13 to 17 years old (N = 310, mean = 16 years, 90% African-American, 66% male) on probation were assigned to a 2-week intervention targeting psychosocial factors implicated in risky behavior (e.g., learning strategies to manage "hot" emotions that prompt risk taking) or to an equally intensive health promotion control. Participants completed aggression measures at baseline, 6-, and 12-month follow-up and reported on incarceration at 12 months. Spline regression tested symptom change. RESULTS: Among clinically aggressive offenders (n = 71), the intervention arm showed significantly greater reductions in aggression over the first 6 months compared with controls. Juveniles from the intervention no longer met clinical criteria, on average, but clinically significant symptoms persisted in the control group. By 12 months, participants from the intervention appeared to maintain treatment gains, but their symptom levels no longer differed significantly from those in the control. However, the intervention group was nearly 4 times less likely than controls to report incarceration. Intervention effects were significantly stronger for offenders with clinical than with nonclinical (n = 239) baseline aggression. CONCLUSION: A 2-week intervention expedited improvements in aggression and reduced incarceration in clinically aggressive juvenile offenders. The findings underscore the importance of directing intervention resources to the most aggressive youth.

PMID- 29173740 TI - The Dissociative Subtype of Posttraumatic Stress Disorder (PTSD) Among Adolescents: Co-Occurring PTSD, Depersonalization/Derealization, and Other Dissociation Symptoms. AB - OBJECTIVE: The purpose of this study was to examine the co-occurrence of posttraumatic stress disorder (PTSD) and dissociation in a clinical sample of trauma-exposed adolescents by evaluating evidence for the depersonalization/derealization dissociative subtype of PTSD as defined by the DSM-5 and then examining a broader set of dissociation symptoms. METHOD: A sample of treatment-seeking, trauma-exposed adolescents 12 to 16 years old (N = 3,081) from the National Child Traumatic Stress Network Core Data Set was used to meet the study objectives. Two models of PTSD/dissociation co-occurrence were estimated using latent class analysis, one with 2 dissociation symptoms and the other with 10 dissociation symptoms. After model selection, groups within each model were compared on demographics, trauma characteristics, and psychopathology. RESULTS: Model A, the depersonalization/derealization model, had 5 classes: dissociative subtype/high PTSD; high PTSD; anxious arousal; dysphoric arousal; and a low symptom/reference class. Model B, the expanded dissociation model, identified an additional class characterized by dissociative amnesia and detached arousal. CONCLUSION: These 2 models provide new information about the specific ways PTSD and dissociation co-occur and illuminate some differences between adult and adolescent trauma symptom expression. A dissociative subtype of PTSD can be distinguished from PTSD alone in adolescents, but assessing a wider range of dissociative symptoms is needed to fully characterize adolescent traumatic stress responses. PMID- 29173741 TI - Traumatic Stress Interacts With Bipolar Disorder Genetic Risk to Increase Risk for Suicide Attempts. AB - OBJECTIVE: Bipolar disorder (BD) is one of the most heritable psychiatric conditions and is associated with high suicide risk. To explore the reasons for this link, this study examined the interaction between traumatic stress and BD polygenic risk score in relation to suicidal ideation, suicide attempt, and nonsuicidal self-injury (NSSI) in adolescent and young adult offspring and relatives of persons with BD (BD-relatives) compared with adolescent and young adult offspring of individuals without psychiatric disorders (controls). METHOD: Data were collected from 4 sites in the United States and 1 site in Australia from 2006 through 2012. Generalized estimating equation models were used to compare rates of ideation, attempts, and NSSI between BD-relatives (n = 307) and controls (n = 166) and to determine the contribution of demographic factors, traumatic stress exposure, lifetime mood or substance (alcohol/drug) use disorders, and BD polygenic risk score. RESULTS: After adjusting for demographic characteristics and mood and substance use disorders, BD-relatives were at increased risk for suicidal ideation and attempts but not for NSSI. Independent of BD-relative versus control status, demographic factors, or mood and substance use disorders, exposure to trauma within the past year (including bullying, sexual abuse, and domestic violence) was associated with suicide attempts (p = .014), and BD polygenic risk score was marginally associated with attempts (p = .061). Importantly, the interaction between BD polygenic risk score and traumatic event exposures was significantly associated with attempts, independent of demographics, relative versus control status, and mood and substance use disorders (p = .041). CONCLUSION: BD-relatives are at increased risk for suicide attempts and ideation, especially if they are exposed to trauma and have evidence of increased genetic vulnerability.

METHOD: This longitudinal study consisted of 3 annual interviews of PR youth (N = 1,150; aged 10-14 years at wave 1) and their caretakers from the South Bronx (SB) in New York City and from San Juan, Puerto Rico. Parents reported on parental risks, parenting behaviors, and YASB. Youth also self-reported on YASB and youth cultural stress. A lagged structural equation model examined the relationship between these variables across 3 yearly waves, with youth cultural stress as a moderator of the association between effective parenting behaviors and YASB. RESULTS: Findings supported the positive influence of effective parenting on YASB, independently of past parental risks and past YASB: higher effective parenting significantly predicted lower YASB at the following wave. Parenting also accounted for (mediated) the association between the composite of parental risks and YASB. Youth cultural stress at wave 1 was cross-sectionally associated with higher YASB and moderated the prospective associations between effective parenting and YASB, such that for youth who perceived higher cultural stress, the positive effect of effective parenting on YASB was weakened compared to those with lower/average cultural stress. CONCLUSION: Among PR families, both parental and cultural risk factors influence YASB. Such findings should be considered when treating racial/ethnic minority youth for whom cultural factors may be a relevant influence on determining behaviors. PMID- 29173743 TI - Clinical Correlates of Carbon Dioxide Hypersensitivity in Children. AB - OBJECTIVE: Hypersensitivity to carbon dioxide (CO2)-enriched air may be a promising risk marker for anxiety disorders. Among adult and adolescent samples, heterogeneity in distress response to the CO2 challenge task indexes 3 underlying classes of individuals, which distinguish between sustained and acute threat response as markers for internalizing disorders, broadly, and anxiety disorders, specifically. The present study examines latent classes in children's response to the CO2 challenge task to clarify the association of CO2 hypersensitivity with anxiety and internalizing symptomatology in childhood. METHOD: Healthy children from a community twin sample (N = 538; age 9-13 years) rated anxious distress every 2 minutes while breathing air enriched to 7.5% CO2 for 8 minutes. Latent growth mixture modeling evaluated potential classes of individuals with characteristic trajectories of distress during the task to clarify the association with internalizing disorder symptoms and related traits (e.g., anxiety sensitivity, irritability). RESULTS: Although all participants reported increased distress during the task, interindividual heterogeneity in distress indexed 3 underlying classes: a consistently low class ("low"), a consistently high class ("high"), and participants who demonstrated markedly increased acute distress ("acute"). Compared to the low class, the high class reported greater internalizing psychopathology, whereas membership in the acute class was associated with experiencing a panic-like event during the task. CONCLUSION: As in older individuals, 3 distinct trajectories emerged to capture interindividual heterogeneity in children's distress during the CO2 challenge task. These classes were distinguished by clinical validators that reinforce the association of CO2 hypersensitivity and internalizing disorder phenotypes in children. PMID- 29173744 TI - A Neurobehavioral Mechanism Linking Behaviorally Inhibited Temperament and Later Adolescent Social Anxiety. AB - OBJECTIVE: Behavioral inhibition (BI) is a temperament identified in early childhood that is a risk factor for later social anxiety. However, mechanisms underlying the development of social anxiety remain unclear. To better understand the emergence of social anxiety, longitudinal studies investigating changes at behavioral neural levels are needed. METHOD: BI was assessed in the laboratory at 2 and 3 years of age (N = 268). Children returned at 12 years, and an electroencephalogram was recorded while children performed a flanker task under 2 conditions: once while believing they were being observed by peers and once while not being observed. This methodology isolated changes in error monitoring (error related negativity) and behavior (post-error reaction time slowing) as a function of social context. At 12 years, current social anxiety symptoms and lifetime diagnoses of social anxiety were obtained. RESULTS: Childhood BI prospectively predicted social-specific error-related negativity increases and social anxiety symptoms in adolescence; these symptoms directly related to clinical diagnoses. Serial mediation analysis showed that social error-related negativity changes explained relations between BI and social anxiety symptoms (n = 107) and diagnosis (n = 92), but only insofar as social context also led to increased post error reaction time slowing (a measure of error preoccupation); this model was not significantly related to generalized anxiety. CONCLUSION: Results extend prior work on socially induced changes in error monitoring and error preoccupation. These measures could index a neurobehavioral mechanism linking BI to adolescent social anxiety symptoms and diagnosis. This mechanism could relate more strongly to social than to generalized anxiety in the peri-adolescent period. PMID- 29173745 TI - Adieuvalence.

AB - Immune system dysfunction plays a role in both the development and progression of head and neck squamous cell carcinoma (HNSCC), highlighting the potential role for immunotherapy to improve outcomes in this disease. The application of anti-PD 1 therapies for recurrent or metastatic HNSCC has found promising results. This has led to interest in combining immunotherapy with radiation therapy (RT) for the primary treatment of locally advanced HNSCC. RT with concurrent cetuximab is an option for patients who are medically unfit to receive cisplatin, and ongoing trials seek to determine to role of cetuximab-RT in treatment de-intensification for HPV+ oropharyngeal HNSCC. Other ongoing trials are evaluating the use of anti PD-1 and anti-PD-L1 therapies in the upfront setting for newly diagnosed high risk, locally advanced HNSCC, in an effort to improve disease control. Finally, early phase I studies are now investigating the use of anti-PD-1 therapy in conjunction with RT for refractory recurrent or metastatic HNSCC. PMID- 29173751 TI - The Current State of Biological and Clinical Implications of Human Papillomavirus Related Oropharyngeal Cancer. AB - In the effort to control human papillomavirus-related oropharyngeal cancer, the head and neck oncology community has devoted much effort to understanding its disease biology and clinical behavior, and refining strategies to address early diagnosis and optimal management for the affected population. This review identifies articles published up to March 2017 on tumor biology and clinical implications of human papillomavirus-related oropharyngeal cancer, and summarizes the findings in some key areas. These include potential screening strategies, possible anatomical features responsible for early lymph node involvement and its implication for staging, biological mechanisms to explain superior outcomes compared to traditional nonviral-related mucosal cancers, re-appreciation of traditional prognostic factors (eg, hypoxia, extranodal extension, and smoking), and current efforts to optimize management for this patient population. The review reflects the global effort to mitigate the influence of this burgeoning disease. PMID- 29173752 TI - Therapeutic Implications of the Genetic Landscape of Head and Neck Cancer. AB - Large-scale sequencing studies of head and neck squamous cell carcinoma (HNSCC) have elucidated the genetic changes that characterize HNSCC. These findings have supported the development of therapeutic strategies that target key components of aberrant signaling pathways and immune dysregulation. Cumulative evidence suggests that these agents in combination with radiotherapy may have synergistic effects. This review highlights the predictive biomarkers that have been identified from HNSCC genomic studies and implications on the development of molecular-targeting agents that may effectively treat patients with HNSCC, especially when used in combination with radiation. PMID- 29173753 TI - Current Status and Future Directions of Treatment Deintensification in Human Papilloma Virus-associated Oropharyngeal Squamous Cell Carcinoma. AB - The prevalence of patients with human papilloma virus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) is rapidly increasing, and it is now well known that these patients have a significantly better prognosis than patients with HPV-negative OPSCC. Though standard treatments result in excellent cancer control, they are also associated with substantial long-term toxicity. There is now great interest in evaluating less intensive (ie, deintensified) treatment regimens to improve the therapeutic ratio (maintain excellent cancer control and decrease toxicity). There are many different approaches that are being studied, and each have their own caveats, with varying degrees of actual deintensification. In this article, we critically review the current landscape of emerging deintensified treatment paradigms and future direction of the treatment of HPV-associated OPSCC. PMID- 29173754 TI - Molecular Imaging-Guided Radiotherapy for the Treatment of Head-and-Neck Squamous Cell Carcinoma: Does it Fulfill the Promises? AB - With the routine use of intensity modulated radiation therapy for the treatment of head-and-neck squamous cell carcinoma allowing highly conformed dose distribution, there is an increasing need for refining both the selection and the delineation of gross tumor volumes (GTV). In this framework, molecular imaging with positron emission tomography and magnetic resonance imaging offers the opportunity to improve diagnostic accuracy and to integrate tumor biology mainly related to the assessment of tumor cell density, tumor hypoxia, and tumor proliferation into the treatment planning equation. Such integration, however, requires a deep comprehension of the technical and methodological issues related to image acquisition, reconstruction, and segmentation. Until now, molecular imaging has had a limited value for the selection of nodal GTV, but there are increasing evidences that both FDG positron emission tomography and diffusion weighted magnetic resonance imaging has a potential value for the delineation of the primary tumor GTV, effecting on dose distribution. With the apprehension of the heterogeneity in tumor biology through molecular imaging, growing evidences have been collected over the years to support the concept of dose escalation/dose redistribution using a planned heterogeneous dose prescription, the so-called "dose painting" approach. Validation trials are ongoing, and in the coming years, one may expect to position the dose painting approach in the armamentarium for the treatment of patients with head-and-neck squamous cell carcinoma. PMID- 29173755 TI - Organ-Sparing in Radiotherapy for Head-and-Neck Cancer: Improving Quality of Life. AB - This is an overview of select studies characterizing the effect of radiation on normal tissues in the treatment of head-and-neck cancer. Recommendations for organ-at-risk dose constraints aiming to reduce risks of xerostomia and dysphagia, the factors which have the highest effect on patient quality of life, are discussed, along with their supporting evidence. Recent advances in technology and biology, and their implications for reducing toxicity are explored. Considerations related to organ-sparing in the setting of treatment deintensification for good-prognosis head-and-neck cancer are also discussed. PMID- 29173756 TI - Proton Therapy for Head and Neck Cancers. AB - Because of its sharp lateral penumbra and steep distal fall-off, proton therapy offers dosimetric advantages over photon therapy. In head and neck cancer, proton therapy has been used for decades in the treatment of skull-base tumors. In recent years the use of proton therapy has been extended to numerous other disease sites, including nasopharynx, oropharynx, nasal cavity and paranasal sinuses, periorbital tumors, skin, and salivary gland, or to reirradiation. The aim of this review is to present the physical properties and dosimetric benefit of proton therapy over advanced photon therapy; to summarize the clinical benefit described for each disease site; and to discuss issues of patient selection and cost-effectiveness. PMID- 29173757 TI - Head and Neck Cancer Survivorship: Learning the Needs, Meeting the Needs. AB - Cancers of the head and neck and the treatments required to control them frequently result in serious and persistent impairments that can affect participation and quality of life. Increased recognition of the needs of cancer survivors and their caregivers has prompted research focused on the unique concerns of this complex group. Unmet needs have been identified among 60-70% of patients and a similar proportion of their partners; impacts can include profound social effects, isolation, and psychiatric conditions. Interprofessional teams, supplementing oncology nursing and physicians with physical rehabilitation, occupational therapy, speech-language pathology, nutrition and psychological disciplines is important to address the spectrum of emotional, cognitive, physical and functional, and pragmatic issues. In addition to investigating modified anti-cancer therapy intended to reduce the frequency of long-term toxicities, supportive care strategies that may be effective include physical activity, nutritional intervention, behavioral and cognitive-behavioral therapy, psycho-education and goal management therapy. This article addresses identified needs across varied domains, the current state of research surrounding them, and their impact on quality of life, while also describing one cancer center's approach to head and neck cancer survivorship. PMID- 29173758 TI - Correction. PMID- 29173759 TI - Early detection of lung cancer using ultra-low-dose computed tomography in coronary CT angiography scans among patients with suspected coronary heart disease. AB - OBJECTIVES: To assess whether an additional chest ultra-low-dose CT scan to the coronary CT angiography protocol can be used for lung cancer screening among patients with suspected coronary artery disease. METHODS: 175 patients underwent coronary CT angiography for assessment of coronary artery disease, additionally undergoing ultra-low-dose CT screening to early diagnosis of lung cancer in the same scanner (80kVp and 15mAs). Patients presenting pulmonary nodules were followed-up for two years, repeating low-dose CTs in intervals of 3, 6, or 12 months based on nodule size and growth rate in accordance with National Comprehensive Cancer Network guidelines. RESULTS: Ultra-low-dose CT identified 71 patients with solitary pulmonary nodules (41%), with a mean diameter of 5.50+/ 4.00mm. Twenty-eight were >6mm, and in 79% (n=22) of these cases they were false positive findings, further confirmed by follow-up (n=20), resection (n=1), or biopsy (n=1). Lung cancer was detected in six patients due to CT screening (diagnostic yield: 3%). Among these, four cases could not be detected in the cardiac field of view. Most patients were in early stages of the disease. Two patients diagnosed at advanced stages died due to cancer complications. The addition of the ultra-low-dose CT scan represented a radiation dose increment of 1.22+/-0.53% (effective dose, 0.11+/-0.03mSv). CONCLUSIONS: Lung cancer might be detected using additional ultra-low-dose protocols in coronary CT angiography scans among patients with suspected coronary artery disease. PMID- 29173760 TI - Targeting DNA damage in SCLC. AB - SCLC accounts for 15% of lung cancer worldwide. Characterised by early dissemination and rapid development of chemo-resistant disease, less than 5% of patients survive 5 years. Despite 3 decades of clinical trials there has been no change to the standard platinum and etoposide regimen for first line treatment developed in the 1970's. The exceptionally high number of genomic aberrations observed in SCLC combined with the characteristic rapid cellular proliferation results in accumulation of DNA damage and genomic instability. To flourish in this precarious genomic context, SCLC cells are reliant on functional DNA damage repair pathways and cell cycle checkpoints. Current cytotoxic drugs and radiotherapy treatments for SCLC have long been known to act by induction of DNA damage and the response of cancer cells to such damage determines treatment efficacy. Recent years have witnessed improved understanding of strategies to exploit DNA damage and repair mechanisms in order to increase treatment efficacy. This review will summarise the rationale to target DNA damage response in SCLC, the progress made in evaluating novel DDR inhibitors and highlight various ongoing challenges for their clinical development in this disease. PMID- 29173761 TI - Matched-pair analysis of a multi-institutional cohort reveals that epidermal growth factor receptor mutation is not a risk factor for postoperative recurrence of lung adenocarcinoma. AB - OBJECTIVE: It is unclear whether epidermal growth factor receptor (EGFR) mutation status is a risk factor for postoperative recurrence of surgically resected lung adenocarcinoma (ADC). Therefore, we conducted a multi-institutional study employing matched-pair analysis to compare recurrence-free survival (RFS) and overall survival (OS) of patients with lung ADC according to EGFR mutation status. METHODS: We collected the records of 909 patients who underwent surgical resection for lung ADC between 2005 and 2012 at five participating institutions and were also examined their EGFR mutation status. For each patient with an EGFR mutation, we selected one with the wild-type EGFR sequence and matched them according to institution, age, gender, smoking history, pathological stage (pStage), and adjuvant treatment. We compared RFS and OS of the matched cohort. RESULTS: The patients were allocated into groups (n=181 each) with mutated or wild-type EGFR sequences. Both cohorts had identical characteristics as follows: institution, median age (68 years), men (85, 47%), ever smokers (77, 43%), and pStage (IA, 108, 60%; IB, 48, 27%; II, 14, 8%; III, 11, 6%). The 3- and 5-year RFS rates of patients with mutated or wild-type EGFR sequence were 79%, 68% and 77%, 68%, respectively (p=0.557). The respective OS rates were 92%, 81%, and 89%, 79% (p=0.574). CONCLUSION: Matched-pair and multi-institutional analysis reveals that an EGFR mutation was not a significant risk factor for recurrence of patients with surgically resected lung adenocarcinoma. PMID- 29173762 TI - Quantification of plasma EGFR mutations in patients with lung cancers: Comparison of the performance of ARMS-Plus and droplet digital PCR. AB - OBJECTIVES: EGFR mutation is a key factor to predict EGFR-TKI efficacy. However, a significant number of advanced patients do not have sufficient tumor specimens for molecular testing. Also, there is a lack of quantitative assay to analyze the mutant abundance. This study aims to evaluate the detection efficiency and clinical feasibility of a new platform, namely ARMS-Plus, for the detection and quantification of EGFR mutations in plasma. MATERIALS AND METHODS: The detection limit of ARMS-Plus was assessed by detecting spiked mutant plasmids which were serially diluted with normal human genomic DNA. The cutoff values were defined by examining the mutant copy numbers presented in 134 healthy controls. Plasma samples from 65 lung cancer patients were collected to evaluate the clinical performance of ARMS-Plus. EGFR mutations were concurrently tested by droplet digital PCR (ddPCR) for the plasma samples and conventional amplification refractory mutation system-PCR (ARMS-PCR) for the matched tumor tissue specimens to serve as a standard for comparison. RESULTS: In this study, the analytical sensitivity of ARMS-Plus was 0.015%. The cutoff values of EGFR 19Del, L858R, T790M mutations were defined as 2, 5, and 3 copies/mL, respectively. With tumor specimens as the standard, the sensitivity, specificity, and concordance rate of ARMS-Plus and ddPCR were 60.7%, 94.6%, and 80.0%; and 50.0%, 97.3%, and 76.9%, respectively. For quantification, the plasma 19Del and L858R mutant abundance detected by ARMS-Plus and ddPCR were consistent (Spearman R=0.7956 and 0.7710, P<0.0001). CONCLUSION: ARMS-Plus is a reliable, convenient and cost-effective method for the detection and quantification of plasma EGFR mutations. PMID- 29173763 TI - Vasculature surrounding a nodule: A novel lung cancer biomarker. AB - PURPOSE: To investigate whether the vessels surrounding a nodule depicted on non contrast, low-dose computed tomography (LDCT) can discriminate benign and malignant screen detected nodules. MATERIALS AND METHODS: We collected a dataset consisting of LDCT scans acquired on 100 subjects from the Pittsburgh Lung Screening study (PLuSS). Fifty subjects were diagnosed with lung cancer and 50 subjects had suspicious nodules later proven benign. For the lung cancer cases, the location of the malignant nodule in the LDCT scans was known; while for the benign cases, the largest nodule in the LDCT scan was used in the analysis. A computer algorithm was developed to identify surrounding vessels and quantify the number and volume of vessels that were connected or near the nodule. A nonparametric receiver operating characteristic (ROC) analysis was performed based on a single nodule per subject to assess the discriminability of the surrounding vessels to provide a lung cancer diagnosis. Odds ratio (OR) were computed to determine the probability of a nodule being lung cancer based on the vessel features. RESULTS: The areas under the ROC curves (AUCs) for vessel count and vessel volume were 0.722 (95% CI=0.616-0.811, p<0.01) and 0.676 (95% CI=0.565 0.772), respectively. The number of vessels attached to a nodule was significantly higher in the lung cancer group 9.7 (+/-9.6) compared to the non lung cancer group 4.0 (+/-4.3) CONCLUSION: Our preliminary results showed that malignant nodules are often surrounded by more vessels compared to benign nodules, suggesting that the surrounding vessel characteristics could serve as lung cancer biomarker for indeterminate nodules detected during LDCT lung cancer screening using only the information collected during the initial visit. PMID- 29173764 TI - Clinical outcomes of black vs. non-black patients with locally advanced non-small cell lung cancer. AB - OBJECTIVES: The black population remains underrepresented in clinical trials despite reports suggesting greater incidence and deaths from locally advanced non small cell lung cancer (NSCLC). We determined outcomes for black and non-black patients in a well-annotated cohort treated with either definitive chemoradiation (CRT; bimodality) or CRT followed by surgery (trimodality therapy). MATERIALS AND METHODS: A retrospective analysis of 355 stage III NSCLC patients treated with curative intent at the University of Maryland, Medical Center, between January 2000-December 2013 was performed. The Kaplan-Meier approach and the Cox proportional hazards models were used to analyze overall survival (OS) and freedom-from-recurrence (FFR) in black and non-black patients. The chi-square test was used to compare categorical variables. RESULTS: Black patients comprised 42% of the cohort and were more likely to be younger (p<0.0001), male (p=0.030), single (p<0.0001), reside in lower household income zipcodes (p<0.0001), have an Eastern Cooperative Oncology Group (ECOG) performance status >0 (p<0.001), and less likely to undergo surgery (p<0.0001). With a median follow-up of 15 months for all patients and 89 months for surviving patients (range:1-186 months), median OS times for black and non-black patients were 22 and 24 months, respectively (p=0.698). FFR rates were also comparable between the two groups (p=0.468). Surgery improved OS in both cohorts. Race was not a significant predictor for OS or FFR even when adjusted for other factors. CONCLUSIONS: We found similar oncologic outcomes in black and non-black NSCLC patients when treated with curative intent in a comprehensive cancer center setting, despite epidemiologic differences in presentation and receipt of care. Future efforts to improve outcomes in black patients could focus on addressing modifiable social disparities. PMID- 29173765 TI - Esophageal ultrasound (EUS) assessment of T4 status in NSCLC patients. AB - BACKGROUND: Mediastinal and central large vessels (T4) invasion by lung cancer is often difficult to assess preoperatively due to the limited accuracy of computed tomography (CT) scan of the chest. Esophageal ultrasound (EUS) can visualize the relationship of para-esophageally located lung tumors to surrounding mediastinal structures. AIM: To assess the value of EUS for detecting mediastinal invasion (T4) of centrally located lung tumors. METHODS: Patients who underwent EUS for the diagnosis and staging of lung cancer and in whom the primary tumor was detected by EUS and who subsequently underwent surgical- pathological staging (2000-2016) were retrospectively selected from two university hospitals in The Netherlands. T status of the lung tumor was reviewed based on EUS, CT and thoracotomy findings. Surgical- pathological staging was the reference standard. RESULTS: In 426 patients, a lung malignancy was detected by EUS of which 74 subjects subsequently underwent surgical- pathological staging. 19 patients (26%) were diagnosed with stage T4 based on vascular (n=8, 42%) or mediastinal (n=8, 42%) invasion or both (n=2, 11%), one patient (5%) had vertebral involvement. Sensitivity, specificity, PPV and NPV for assessing T4 status were: for EUS (n=74); 42%, 95%, 73%, 83%, for chest CT (n=66); 76%, 61%, 41%, 88% and the combination of EUS and chest CT (both positive or negative for T4, (n=34); 83%, 100%, 100% 97%. CONCLUSION: EUS has a high specificity and NPV for the T4 assessment of lung tumors located para-esophageally and offers further value to chest CT scan. PMID- 29173766 TI - Changing costs of metastatic non small cell lung cancer in the Netherlands. AB - OBJECTIVES: The primary objective of this study was to identify the total intramural cost of illness of metastatic non-small cell lung cancer (NSCLC) in the Netherlands between 2006-2012. Secondary objective was to identify whether changes in cost patterns of metastatic NSCLC have occurred over the last years. METHODS: Patients diagnosed with metastatic NSCLC between 1-1-2006 and 31-12 2012, who had follow-up to death or the date of data cut-off and no trial participation were included. A structured chart review was performed using a case report form. Data collection started after diagnosis of metastatic NSCLC and ended at death or April first, 2015. Data regarding outpatient visits, clinical attendance, oncolytic drug use, imaging, lab tests, radiotherapy and surgery were collected. RESULTS: Sixty-seven patients were included with a median age of 67 years. The median follow-up was 234days. On average patients had 28 outpatient visits and 11 inpatient days. Oncolytic drugs were administered to 76% of the patients. Mean per patient expenditures amounted up to ?17,463, with oncolytic drugs (?6,390) as the main cost driver. In comparison with the time-period of 2003-2005 total per patient per year expenses decreased by 44%. The contribution to total yearly costs of oncolytic drugs increased from 18% to 35%, while costs for inpatient stay decreased from 52% to 28% of total expenditures. CONCLUSION: Outcomes in this study demonstrate that average treatment costs for metastatic NSCLC in the Netherlands Cancer Institute amount to ?17,463. Compared to a prior study the average cost for metastatic NSCLC over time in the Netherlands has decreased. A shift of main cost drivers seems to have occurred from inpatient stay, to oncolytic drugs as main contributor. The shift towards treatment cost might become more visible with the introduction of immunotherapy. These results mark the importance of up-to-date cost of illness studies. PMID- 29173767 TI - Identification of a serum microRNA expression signature for detection of lung cancer, involving miR-23b, miR-221, miR-148b and miR-423-3p. AB - OBJECTIVES: Serum mircoRNAs (miRNAs), with their noticeable stability and unique expression pattern in patients with various diseases, are powerful novel non invasive biomarkers for cancer detection. The objective of this study was to identify specific serum miRNAs as potential diagnostic markers for detection of lung cancer. MATERIALS AND METHODS: The expression of serum miRNA from treatment naive lung cancer patients (LC), benign pulmonary disease patients (PD) and healthy controls (HC) were examined by PCR array. The study was divided into two phases: the biomarker-screening phase and the biomarker-validation phase. Logistic regression and receiver operating characteristics curve analyses were used to identify differentially expressed miRNA signatures that could distinguish LC from PD and HC. In addition, target genes of miRNAs were predicted using bioinformatic assays. RESULTS: Ten miRNAs (let-7f, miR-126-3p, miR-148b, miR-151 5p, miR-199a-3p, miR-221, miR-23b, miR-26a, miR-27b, and miR-423-3p) in LC were significantly increased compared to those in PD and HC in biomarker-validation phase (P<0.05). Bioinformatic analyses showed that predicted targets of these miRNAs might have a correlation with formation and development of cancer. Furthermore, we have developed classifiers including 4 miRNAs (miR-23b, miR-221, miR-148b and miR-423-3p) that can be demonstrated as a signature for LC detection, yielding a receiver operating characteristic curve area of 0.885. CONCLUSION: our findings define a distinct miRNA expression profile in LC cases. These 4-miRNA signatures (miR-23b, miR-221, miR-148b and miR-423-3p) may be considered as novel, non-invasive biomarker for LC diagnosis. PMID- 29173768 TI - C-reactive protein-albumin ratio is an independent prognostic predictor of tumor recurrence in stage IIIA-N2 lung adenocarcinoma patients. AB - OBJECTIVE: To systematically evaluate the prognostic value of nutrition/inflammation-based markers for recurrence-free survival (RFS) in pN2 stage IIIA lung adenocarcinoma patients. MATERIALS AND METHODS: Data from 156 patients who had pathologically confirmed pN2-stage IIIA primary lung adenocarcinoma and received complete surgical resection from 2010 to 2014 were retrospectively analyzed. The data for Glasgow prognostic score (GPS), modified GPS (mGPS), high-sensitivity mGPS, C-reactive protein/albumin ratio (CAR), neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, and prognostic nutritional index were analyzed. Univariate and multivariate Cox proportional hazards regression analyses were used to identify the prognostic factors associated with RFS. RESULTS: The optimal cutoff value for the CAR was set at 0.6. A significant correlation was found between the CAR and RFS (P=0.001) by univariate analysis. Multivariate analysis between RFS and the factors selected from univariate analysis showed that ECOG performance status, pneumonectomy, multi-level N2, and high CAR were independent predictors of RFS. CONCLUSION: The CAR was the best prognostic marker to predict tumor recurrence in pN2-stage IIIA lung adenocarcinoma patients among the 7 nutrition/inflammation-based markers. The preoperative CAR may identify patients with a high risk of postoperative tumor recurrence. PMID- 29173769 TI - Durable response to osimertinib in EGFR mutated T790M wildtype non-small cell lung cancer with leptomeningeal metastases: A case report. AB - In patients with non-small cell lung cancer (NSCLC) progression with leptomeningeal (LM) metastases is a catastrophic event with limited treatment options. We report a patient who developed leptomeningeal disease while on front line erlotinib. High-dose tyrosine kinase inhibitor was started but ineffective. She was transitioned to third-generation TKI osimertinib, despite lacking a T790M mutation, and responded with complete resolution of symptoms and malignant cytology in the cerebrospinal fluid (CSF). Recent phase one data and our case indicate osimertinib should be viewed as a best practice for treatment of LM disease in epidermal growth factor receptor (EGFR) mutated NSCLC regardless of T790M status. PMID- 29173770 TI - Circulating metabolite profiles to predict overall survival in advanced non-small cell lung cancer patients receiving first-line chemotherapy. AB - OBJECTIVES: The prognosis for advanced-stage non-small cell lung cancer (NSCLC) is usually poor. However, survival may be variable and difficult to predict. In the current study, we aimed to identify circulating metabolites as potential predictive biomarkers for overall survival of advanced-stage (III/IV) NSCLC patients treated with first-line platinum-based chemotherapy. MATERIALS AND METHODS: Using two-stage study design, we performed global metabolomic profiling in blood of 220 advanced-stage NSCLC patients, including 110 with poor survival and 110 with good survival. Metabolomic profiling was conducted using Metabolon platform. The association of each metabolite with survival was assessed by Cox proportional hazard regression model with adjustment for covariates. RESULTS AND CONCLUSION: We found levels of 4 metabolites, caffeine, paraxanthine, stachydrine, and methyl glucopyranoside (alpha+beta), differed significantly between NSCLC patients with poor and good survival in both discovery and validation phases (P<0.05). Interestingly, majority of the identified metabolites are involved in caffeine metabolism, and 2 metabolites are related to coffee intake. In fact, caffeine metabolism pathway was the only significant pathway identified which significantly differed between NSCLC patients with poor and good survival (P=1.48E-07) in the pathway analysis. We also found 4 metabolites whose levels were significantly associated with good survival in both discovery and validation phases. Strong cumulative effects on overall survival were observed for these 4 metabolites. In conclusion, we identified a panel of metabolites including metabolites in caffeine metabolism pathway that may predict survival outcome in advanced-stage NSCLC patients. The identified small metabolites may be useful biomarker candidates to help identify patients who may benefit from platinum-based chemotherapy. PMID- 29173771 TI - Genetic predisposition to lung adenocarcinoma among never-smoking Chinese with different epidermal growth factor receptor mutation status. AB - OBJECTIVES: The inconsistent findings from genetic association studies may be related to the heterogeneity in different molecular subtypes of lung cancer. This study evaluated the predisposing single-nucleotide polymorphisms (SNPs) in epidermal growth factor receptor (EGFR) mutant and EGFR wild-type lung adenocarcinoma separately among never-smokers. MATERIALS AND METHODS: This was a two-stage case-control study. Never-smokers with pathologically confirmed lung adenocarcinoma and healthy controls were recruited in Hong Kong and Macau. Genomic DNA was extracted and genotyped by MassARRAY. In the discovery stage, 51 SNPs were investigated at the SNP, gene and pathway level among 103 EGFR mutant and 78 EGFR wild-type lung adenocarcinoma cases compared with matched controls. In the validation stage, SNPs that were identified with significant lung cancer risk were replicated in a separate cohort of 84 lung adenocarcinoma cases and compared with 103 Chinese Han, Beijing and 105 Chinese Han, Southern public controls from the 1000 genome database. RESULTS AND CONCLUSION: The genetic association of IL-6 rs2069840 with EGFR mutant lung adenocarcinoma was ascertained. In the discovery stage, haplotype GGG in three SNPs (rs2069840, rs2069852, rs2066992) of IL-6, synergetic effects of IL-6 rs2069840 and environmental tobacco smoke in the workplace were found to be related to EGFR mutant lung adenocarcinoma. ERCC2 rs238406 showed a marginally significant association with EGFR mutant lung adenocarcinoma in the validation stage (P=0.096). ERCC2 rs50871 and ATM rs611646 showed significant association with EGFR wild-type lung adenocarcinoma in the discovery stage. In conclusion, IL-6 rs2069840 conferred susceptibility to EGFR mutant lung adenocarcinoma in a Hong Kong and Macau never-smoking Chinese population.

AB - OBJECTIVES: To investigate the clinical characteristics of anaplastic lymphoma kinase (ALK) rearrangements and sequence complexity of the ALK fusion gene in Chinese lung cancer patients. METHODS: We prospectively screened ALK rearrangements in 1474 lung cancer specimens, including 1387 cases of non-small cell lung cancer (NSCLC), 54 cases of small cell lung cancer (SCLC), and 33 cases of cancer with lung metastasis from other organs by both standard polymerase chain reaction (PCR) and rapid amplification of cDNA ends (RACE)-coupled PCR. Fifteen cases of ALK-positive RACE-coupled PCR products were transformed into Escherichia coli for molecular cloning and sequenced for complexity analysis. RESULTS: The overall frequency of ALK rearrangements was 5.1% (71/1387) in NSCLC. In 71 positive cases, the coexistence of epidermal growth factor receptor (EGFR) and ALK variations was found in 6 cases (8.5%), and the coexistence of different ALK variants was found in 2 cases (2.8%) (1 case with variants 1 and 9; the other case with variants 3 and 2) by PCR analysis. Furthermore, through sequence cloning analysis of 15 cases of non-selective ALK-positive samples, two cases with variants 1 and 3 harbored the coexistence of three subtypes (variant 1 subtypes: E13; A20, E13del63; A20 and E7E12E13; A20 and variant 3 subtypes: E6; A20, E6ins33; A20 and E3E6; A20). Variant 3a and 3b subtypes were always coexistent and had the same proportion of ALK variant 3 rearrangements. ALK rearrangement was associated with young age, female gender, never-smokers, those with adenocarcinoma, advanced stage, and EGFR mutations. No ALK fusion was detected in 54 cases of SCLC or 33 cases of cancer with lung metastasis from other organs. CONCLUSIONS: The identification of novel ALK variants, the coexistence of EGFR mutations and ALK fusions, the coexistence of ALK variants, and the coexistence of subtypes reveal the diversity and sequence complexity of ALK fusions.

PMID- 29173773 TI - A comprehensive review of uncommon EGFR mutations in patients with non-small cell lung cancer. AB - INTRODUCTION: Patients with non-small cell lung cancer (NSCLC) harboring uncommon epidermal growth factor receptor (EGFR) mutations are a heterogeneous group exhibiting differential responses to EGFR inhibitors. This retrospective study reviews the prevalence of uncommon EGFR mutations in a Chinese NSCLC cohort and the clinical characteristics and efficacy of EGFR tyrosine kinase inhibitors (TKIs) associated with these patients. MATERIALS ANDMETHODS: A total of 5363 lung cancer patients were screened and underwent EGFR genotyping at the Guangdong Lung Cancer Institute. Of those with uncommon EGFR mutations, the clinical characteristics and responses to EGFR-TKIs were reviewed retrospectively. RESULTS: Uncommon EGFR mutations were observed in 218 patients, comprising 11.9% of all patients with documented EGFR mutations. More smokers (30.7% vs. 24.3%, P=0.039) and males (54.1% vs. 44.4%, P=0.007) were among the patients with uncommon mutations compared with common mutations. The most frequent uncommon mutations were exon 20 insertions (30.7%, n=67), followed by G719X mutations (21.1%, n=46) and compound L858R mutations (17.0%, n=37). Favorable efficacy was observed in patients harboring compound L858R or G719X mutations, with a median progression-free survival (PFS) of 15.2 (95% CI: 8.7-21.7) or 11.6 (95% CI: 3.6 19.6) months, respectively. The median PFS of those with the T790M mutation or an exon 20 insertion was 1.0 (95% CI: 0.0-2.2) and 3.0 (95% CI: 1.3-4.7) months, respectively. CONCLUSION: This study reviewed the prevalence of uncommon EGFR mutations and their sensitivity to EGFR-TKIs. Favorable responses were observed in patients with G719X and compound L858R mutations, indicating that they may benefit from EGFR-TKIs as a first-line therapy. PMID- 29173775 TI - Comparison of early versus delayed strategies for repair of congenital diaphragmatic hernia on extracorporeal membrane oxygenation. AB - PURPOSE: For the last seven years, our institution has repaired infants with CDH that require ECMO early after cannulation. Prior to that, we attempted to decannulate before repair, but repaired on ECMO if we were unable to wean after two weeks. This study compares those strategies. METHODS: From 2002 to 2016, 65 infants with CDH required ECMO. 67.7% were repaired on ECMO, and 27.7% were repaired after decannulation. Data were compared between patients repaired <=5days after cannulation ("early protocol", n=30) and >5days after cannulation or after de-cannulation ("late protocol", n=35). We used Cox regression to assess differences in outcomes between groups. RESULTS: Survival for the early and late protocol groups was 43.3% and 68.8%, respectively (p=0.0485). For patients that were successfully decannulated before repair, survival was 94.4%. Moreover, the early repair protocol was associated with prolongation of ECMO (16.8+/-7.4 vs. 12.6+/-6.8days, p=0.0216). After multivariate regression, the early repair protocol was an independent predictor of both mortality (HR=3.48, 95% CI=1.28 9.45, p=0.015) and days on ECMO (IRR=1.39, 95% CI=1.07-1.79, p=0.012). All bleeding occurred in patients repaired on ECMO (29.5%, 13/44). CONCLUSIONS: Our data suggest that protocolized CDH repair early after ECMO cannulation may be associated with increased mortality and prolongation of ECMO. However, early repair is not necessarily harmful for those patients who would otherwise be unable to wean from ECMO before repair. Further work is needed to better move towards individualized patient care. TYPE OF STUDY: Treatment Study. LEVEL OF EVIDENCE: Level III. PMID- 29173776 TI - Out of Africa: Insights from a prospective pediatric surgery database. AB - In this year's Robert E. Gross lecture, I describe how experiences early in my career at a government referral hospital in Banjul, The Gambia, influenced my research. Collecting prospective data on all children presenting to the hospital with surgical problems allowed me to gain an understanding of the epidemiology of childhood surgical conditions in sub-Saharan Africa and an appreciation for the inherent challenges of delivering surgical care in settings of limited resources. Based on findings from this database, my research over the past 20years has focused on developing strategies for improving surgical care in low-income countries and better understanding the geographical variations that occur in some of the most common surgical conditions in high-income countries (e.g., appendicitis). Although this research continues to be a work-in-progress, it has the potential to improve the surgical care of children in both high- and low income countries. Much of this research would not have been possible had I not ventured off the usual path for an academic surgeon. PMID- 29173777 TI - Surgical excision is the treatment of choice for cervical lymphatic malformations with mediastinal expansion. AB - BACKGROUND: Lymphatic malformations (LMs) in the mediastinum are uncommon. However, cervical LMs may expand into the mediastinum. The aim of this study was to review our experience with the management of patients with LMs involving the mediastinum and to propose a treatment algorithm to guide the management of these rare malformations. MATERIAL AND METHODS: This was a descriptive retrospective chart review of all patients with LMs involving the mediastinum treated at our Institution between 2009 and 2015. We collected demographic data, data on investigations, management, and complications of the treatment, as well as outcomes at follow-up. Complications were defined and described according to the Clavien-Dindo classification. The clinical outcome was assessed using a clinical assessment scale. RESULTS: The cohort consisted of seven patients. Airway compromise at the time of diagnosis was seen in 4 patients. Three patients had anatomical compression of the trachea and two patients had sub-total compression of the right lung. All three patients with tracheoscopy-verified compression of the trachea had compromise of the distal trachea, and a tracheostomy would not have been protective. All patients received sclerotherapy. The median time with mechanical ventilation at the neonatal intensive care unit after each sclerotherapy was eleven days (range 8-31). Each patient received sclerotherapy in median three times (range 1-9). Five of the patients (71%) were operated with excision of the LM in the mediastinum. Two of the patients were operated primarily and three patients were operated after major complications to sclerotherapy. The patients treated with sclerotherapy and the operated patients had comparable amount of mild complications, Clavien-Dindo grade I-II complications. Severe complications, Clavien-Dindo grade III-IV, were seen five times more commonly after sclerotherapy than after surgery. The clinical outcome was excellent for the operated patients and fair to good for the patients receiving only sclerotherapy. CONCLUSION: Patients with cervical LM involving the mediastinum represent a high-risk group with respect to the severity of complications following sclerotherapy. The swelling is unpredictable and requires extended observation at an intensive care unit with ventilation support. Tracheostomy does not prevent tracheal compression in mediastinal LM, as the malformation may compress trachea distal to the stoma. Surgical resection of the LM in the mediastinum is recommended, with the possibility of intra-operative sclerotherapy as an adjunctive. LEVEL OF EVIDENCE: IV. PMID- 29173778 TI - Assessing the long term manometric outcomes in patients with previous laparoscopic anorectoplasty (LARP) and posterior sagittal anorectoplasty (PSARP). AB - BACKGROUND/PURPOSE: The objective of this study is to compare the long term manometric outcomes in patients with previous laparoscopic anorectoplasty (LARP) and posterior sagittal anorectoplasty (PSARP). METHODS: This is a single-centered retrospective study and the participants were born with various types of anorectal malformation. Manometric assessment was carried out with high resolution anorectomanometry performed as a day procedure. In addition, a seven itemed bowel function score (BFS) was utilized to assess the functional outcomes. RESULTS: A total of 30 patients were included in this study (PSARP=14, LARP=16) and the median follow up periods were 15.5years and 9years in the PSARP and LARP groups respectively (p=0.06). The median value of BFS was significantly lower in the PSARP group (PSARP=12.5, range: 8-18; LARP=16, range: 10-20, p=0.03). The median value of sphincteric resting pressure was 20mmHg (range: 10-50mmHg) in the PSARP group and 40mmHg (range: 10-70mmHg) in the LARP group (p=0.05). There was no significant difference in following measurements: the percentage of patient having a normal sphincteric resting pressure (PSARP vs LARP=50% vs 75%, p=0.28); the median sphincteric squeeze pressure (PSARP vs LARP=30mmHg, range: 10-100 vs 50mmHg, range: 20-140mmHg, p=0.08); the incidence of rectoanal inhibitory reflex (RAIR) (PSARP vs LARP=42.9% vs 31.3%, p=0.14) and the median value for volume of air to elicit the first anal sensation (PSARP vs LARP=30ml, range: 20-60ml vs 40ml, range: 20-80ml, p=0.18). CONCLUSION: Anorectomanometry is a useful follow up study after anorectoplasty and majority of the patients with previous LARP could retain a normal sphincteric resting pressure during long term follow up. Comparing the two surgical approaches, patients with previous LARP could achieve a higher bowel function score as well as sphincter resting pressure in manometric assessment.

AB - Pediatric legislation has generated information about the efficacy, safety, and dosing of more than 600 products in children. Extrapolation of adult efficacy data has been an integral part of pediatric drug development. Advances in our understanding of physiology and pharmacology have improved the approach to pediatric dose selection. However, a high percentage of pediatric trials do not meet their primary efficacy endpoint. Delays in initiating completing pediatric studies persist. This article describes these advances and provides innovative approaches to optimize pediatric drug development. PMID- 29173780 TI - Approaching Current and New Drug Therapies for Pediatric Asthma. AB - As new therapies for pediatric asthma are approved by the Food and Drug Administration, clinicians should be aware of their benefits and limitations. Accompanying these therapies are potential obstacles, including the delivery of inhaled therapies and age-specific issues regarding implementation and adherence. New insights are being added to well-established controller medications, including inhaled corticosteroids and long-acting beta-agonists, while new medications previously approved in adults, including tiotropium and biologics, are now being evaluated for use in children. These drugs can be useful additive therapies to treat patients who are currently not responding to guidelines-based therapy. PMID- 29173781 TI - Psychopharmacology of Bipolar Disorders in Children and Adolescents. AB - Bipolar disorder is a debilitating illness that often leads to functional impairment when untreated. Monotherapy with mood stabilizers is preferable, although combination therapy may be necessary in refractory cases. Most studies focus on the use of lithium, anticonvulsants, and second-generation antipsychotics in the treatment of acute manic or depressive phases, as well as maintaining adequate response after the episode. More research is needed in the area of psychopharmacology of pediatric bipolar disorder to bridge the gap between clinical needs and the available data. PMID- 29173782 TI - New Psychoactive Substances in Pediatric Patients. AB - New psychoactive substances (NPS), namely cannabinoids, cathinones, and opioids, have surged in popularity among school-age children, resulting in serious morbidity and mortality globally. In the last decade, there has been a rapid evolution of NPS resulting in hundreds of new compounds. Little to no evidence for humans is available on most compounds. The clinical presentations of patients intoxicated with cannabinoids and cathinones are highly variable but most commonly present with a sympathomimetic toxidrome, for example, agitation, delirium, and tachycardia. Those with opioids present with a classic opioid toxidrome: coma, dilated pupils, and respiratory failure. PMID- 29173783 TI - Dietary Supplements in Children. AB - High-quality systematic reviews of use of herbal or homeopathic remedies in children often suffer from design flaws, such as not following PRISMA guidelines, inconsistent outcome measurements, and paucity of high-quality studies. Herbal remedies have modest demonstrated benefits with insufficient evidence to recommend any particular supplement. Homeopathic remedies have no role in treatment of pediatric conditions, and have been associated with great harm in infants given homeopathic teething products. Two types of herbal supplements are associated with high risk in adolescents, energy drinks and adulterated weight loss products. Parents should be counseled about risks of these products. PMID- 29173784 TI - Anticoagulation Therapies in Children. AB - Venous thromboembolism is occurring with increasing frequency in children resulting in the more widespread use of anticoagulation in pediatrics. Antithrombotic drugs in children can be divided into the standard and alternative agents. This review discusses standard and alternative anticoagulants. Because standard anticoagulants have significant limitations, including variable pharmacokinetics, issues with therapeutic drug monitoring, frequency of administration, efficacy, and adverse effects, it is expected that the use of alternative anticoagulants will increase over time. With their improved properties and recent prospective clinical trial data, the current and future use of these agents will likely slowly replace of the standard anticoagulants. PMID- 29173785 TI - Probiotics in Newborns and Children. AB - Microbes and humans have been closely associated throughout evolution; this symbiotic and/or commensal relationship is crucial for normal development and health. The use of probiotics has been the topic of intense investigation in the past couple of decades because they have the capability to promote health. Based on these studies, it can be debated whether they are being used to promote overall health or to treat and prevent diseases. This review provides an overview and analysis of evidence about what is currently known about the health benefits of these agents that are marketed for use in children and neonates. PMID- 29173786 TI - Drug Treatment of Seizures and Epilepsy in Newborns and Children. AB - The mainstay of treatment of childhood epilepsy is to administer antiepileptic drugs (AEDs). This article provides an overview of the clinical approach to drug treatment of childhood epilepsy, focusing on general principles of therapy and properties of recently introduced medications. Initiation and cessation of therapy, adverse medication effects, drug interactions, indications for the various AEDs, and off-label use of AEDs are reviewed. The distinct challenges in treatment of epileptic spasms and neonatal seizures are addressed. Finally, ideas for the future of drug treatment of childhood epilepsy are presented, with particular attention to precision medicine. PMID- 29173787 TI - Therapeutic Drug Monitoring in Inflammatory Bowel Disease: History and Future Directions. AB - Clinical trials for the most effective drugs in the armamentarium of medications for inflammatory bowel disease (IBD) have shown only a 50-60% response rate, and this drops to 30% in maintenance. However, therapeutic drug monitoring (TDM) to adjust dosing to account for patient-specific characteristics, which has been shown to improve outcomes, was not utilized in these trials. This review will detail the development of TDM within the IBD space as it evolved from thiopurines to biologics and continues to evolve with loftier treat-to-target goals and more sophisticated dashboard systems. PMID- 29173788 TI - Non-steroidal Anti-inflammatory Drugs in Newborns and Infants. AB - Nonsteroidal antiinflammatory drugs (NSAIDs) and acetaminophen are used in young infants and newborns for pain and fever control, patent ductus closure, prevention of intraventricular hemorrhage, and potentially for prevention of retinopathy of prematurity. These drugs inhibit cyclooxygenase 1 (COX-1), COX-2, and peroxidases, thus, blocking prostaglandin (PG) synthesis. PGs are eicosanoids that regulate several physiologic, pathologic, and cellular processes, including vasomotor tone, platelet aggregation, sensitization of neurons to pain, and many molecular events critical to physiologic homeostasis. NSAIDs inhibit caspases and cell death. Increasing knowledge of these molecular entities may allow targeted drug development to prevent or minimize neonatal morbidities. PMID- 29173789 TI - Metformin Use in Children and Adolescents with Prediabetes. AB - With the increasing incidence of childhood obesity, clinicians need to understand its comorbidities and their management. The American Diabetes Association recommends pediatricians screen high-risk overweight and obese children. Identifying and treating prediabetic children and adolescents can help to reduce the burden of type 2 diabetes. Lifestyle interventions are pivotal. Metformin is the only oral medication approved for diabetes treatment in children. It has been studied in clinical trials in nondiabetic children and has been shown to have beneficial effects on body weight. Effects on diabetes prevention have not been studied and long-term data are limited in the pediatric population. PMID- 29173790 TI - Inhaled Drugs and Systemic Corticosteroids for Bronchopulmonary Dysplasia. AB - All definitions of bronchopulmonary dysplasia (BPD) have limitations and a new definition for the purpose of clinical research, benchmarking, and prognostic prediction is needed. Different inhaled and systemic drugs are currently used to prevent or treat BPD. Despite some positive effects on BPD, more information about the effects of inhaled corticosteroids is required to assess overall efficacy and associated risks. One needs to balance the risks of neurodevelopmental impairment owing to systemic corticosteroids against those of BPD itself. Future studies should, therefore, focus on infants with a very high risk of developing BPD and include pharmacokinetics and long-term developmental outcomes. PMID- 29173791 TI - New Antimicrobial Agents for the Treatment of Staphylococcal Infections in Children. AB - Several new antimicrobial agents-daptomycin, ceftaroline, telavancin, dalbavancin, and-tedizolid have been approved for the treatment of staphylococcal infections, including methicillin-resistant Staphylococcus aureus (MRSA), in adults. Ceftaroline and daptomycin have been approved by the US Food and Drug Administration for use in children. Ceftaroline, a beta-lactam antibiotic with activity against MRSA, has been approved for treatment of community-acquired bacterial pneumonia and complicated skin and skin structure infections. Daptomycin has been approved for treatment of complicated skin and skin structure infections. In this article, we review the pharmacokinetics and pharmacodynamics of these antibiotics and available data on use in children. PMID- 29173792 TI - Antifungal Drugs in Newborns and Children. AB - Invasive fungal infections are a significant cause of morbidity and mortality in infants and children. Early diagnosis is critical, and treatment with the appropriate drug and dose should be initiated promptly. Although an increasing number of studies have examined dosing of antifungals in this population, pediatric safety and efficacy data are lacking. PMID- 29173793 TI - Antiviral Drugs in Newborn and Children. AB - This article focuses on the clinically relevant approved antiviral medications available for the treatment of infants and children. A brief overview of drug categories, mechanism of action, resistance, pharmacokinetics, and side effects is provided for the more commonly prescribed antivirals. The patient categories addressed are treatment and prophylaxis of influenza, neonatal herpes simplex virus and congenital cytomegalovirus, treatment and prophylaxis of viral disease in the immunocompromised host, and a brief introduction to the antivirals available to treat hepatitis B and hepatitis C in children. PMID- 29173794 TI - Drug Dosing in Obese Children: Challenges and Evidence-Based Strategies. AB - With the alarming increase of obesity in children, pediatricians are increasingly being confronted with difficult dosing decisions. Many drug labels do not provide specific dosing instructions for children who are obese. In this article, we describe the physiologic parameters altered by obesity and their influences on drug disposition and effect. We review the principles of allometry, and the key pharmacokinetic parameters that can be used to derive age appropriate dosing regimens. Last, we illustrate how appropriate weight descriptors can be selected, and how important PK parameters can be extrapolated for dosing in obese children when pediatric pharmacokinetic information is available.

PMID- 29173797 TI - The Effects of Massage Therapy on Pain and Anxiety after Surgery: A Systematic Review and Meta-Analysis. AB - Pain management is critical for patients after surgery, but current pain management methods are not always adequate. Massage therapy may be a therapeutic complementary therapy for pain. Many researchers have investigated the effects of massage therapy on post-operative pain, but there have been no systematic reviews and meta-analysis of its efficacy for post-operative patients. Our objective was to assess the effects of massage therapy on pain management among post-operative patients by conducting a systematic review and meta-analysis. The databases searched included MEDLINE, CINAHL, and the Cochrane Library's CENTRAL. To assess the effects of massage therapy on post-operative pain and anxiety, we performed a meta-analysis and calculated standardized mean difference with 95% CIs (Confidential Intervals) as a summary effect. Ten randomized controlled trials were selected (total sample size = 1,157). Meta-analysis was conducted using subgroup analysis. The effect of single dosage massage therapy on post-operative pain showed significant improvement (-0.49; 95% confidence intervals -0.64, 0.34; p < .00001) and low heterogeneity (p = .39, I2 = 4%), sternal incisions showed significant improvement in pain (-0.68; -0.91, -0.46; p< .00001) and low heterogeneity (p = .76, I2 = 0%). The anxiety subgroups showed substantial heterogeneity. The findings of this study revealed that massage therapy may alleviate post-operative pain, although there are limits on generalization of these findings due to low methodological quality in the reviewed studies. PMID- 29173798 TI - Portable CT Pulmonary Angiogram in an Infant on Veno-Arterial Extracorporeal Membrane Oxygenation in the Pediatric Intensive Care Unit. AB - PURPOSE: Computed tomography (CT) has been shown to change management in children on extracorporeal membrane oxygenation (ECMO). Although techniques have been described to transport these critically ill patients to the CT suite in the radiology department, transport out of the intensive care setting is not without risk, and using portable CT is a practical alternative. However, obtaining a CT pulmonary angiogram (CTPA) in a patient on veno-arterial (VA) ECMO presents unique challenges due to bypass of the cardiopulmonary system, which may lead to suboptimal opacification of the pulmonary arteries. METHODS: We describe a method to obtain a diagnostic CTPA study in an infant on VA ECMO in the intensive care unit using portable CT. Our solution involved temporary withholding ECMO and using the venous cannula to deliver a compact contrast bolus to the right atrium to adequately opacify the pulmonary arteries. Special attention was given to the delivery of the contrast bolus, which was given by hand injection, to ensure it coincided with image acquisition and minimized the time ECMO was withheld. RESULTS: We were able to successfully obtain a diagnostic CTPA study in an infant on VA ECMO in the intensive care unit using portable CT. CONCLUSION: This case demonstrates that in select instances CTPA in infants on VA ECMO can be achieved using a portable CT system. PMID- 29173799 TI - Microtubule-Organizing Centers: Towards a Minimal Parts List. AB - Despite decades of molecular analysis of the centrosome, an important microtubule organizing center (MTOC) of animal cells, the molecular basis of microtubule organization remains obscure. A major challenge is the sheer complexity of the interplay of the hundreds of proteins that constitute the centrosome. However, this complexity owes not only to the centrosome's role as a MTOC but also to the requirements of its duplication cycle and to various other functions such as the formation of cilia, the integration of various signaling pathways, and the organization of actin filaments. Thus, rather than using the parts lists to reconstruct the centrosome, we propose to identify the subset of proteins minimally needed to assemble a MTOC and to study this process at non-centrosomal sites.

PMID- 29173800 TI - Zebrafish Infection: From Pathogenesis to Cell Biology. AB - The study of host-pathogen interactions has illuminated fundamental research avenues in both infection and cell biology. Zebrafish (Danio rerio) larvae are genetically tractable, optically accessible, and present a fully functional innate immune system with macrophages and neutrophils that mimic their mammalian counterparts. A wide variety of pathogenic bacteria have been investigated using zebrafish models, providing unprecedented resolution of the cellular response to infection in vivo. In this review, we illustrate how zebrafish models have contributed to our understanding of cellular microbiology by providing an in vivo platform to study host-pathogen interactions from the single cell to whole animal level. We also highlight discoveries made from zebrafish infection that hold great promise for translation into novel therapies for humans. PMID- 29173802 TI - White blood cells identification system based on convolutional deep neural learning networks. AB - BACKGROUND AND OBJECTIVES: White blood cells (WBCs) differential counting yields valued information about human health and disease. The current developed automated cell morphology equipments perform differential count which is based on blood smear image analysis. Previous identification systems for WBCs consist of successive dependent stages; pre-processing, segmentation, feature extraction, feature selection, and classification. There is a real need to employ deep learning methodologies so that the performance of previous WBCs identification systems can be increased. Classifying small limited datasets through deep learning systems is a major challenge and should be investigated. METHODS: In this paper, we propose a novel identification system for WBCs based on deep convolutional neural networks. Two methodologies based on transfer learning are followed: transfer learning based on deep activation features and fine-tuning of existed deep networks. Deep acrivation featues are extracted from several pre trained networks and employed in a traditional identification system. Moreover, a novel end-to-end convolutional deep architecture called "WBCsNet" is proposed and built from scratch. Finally, a limited balanced WBCs dataset classification is performed through the WBCsNet as a pre-trained network. RESULTS: During our experiments, three different public WBCs datasets (2551 images) have been used which contain 5 healthy WBCs types. The overall system accuracy achieved by the proposed WBCsNet is (96.1%) which is more than different transfer learning approaches or even the previous traditional identification system. We also present features visualization for the WBCsNet activation which reflects higher response than the pre-trained activated one. CONCLUSION: a novel WBCs identification system based on deep learning theory is proposed and a high performance WBCsNet can be employed as a pre-trained network. PMID- 29173803 TI - 1H-detected MAS solid-state NMR experiments enable the simultaneous mapping of rigid and dynamic domains of membrane proteins. AB - Magic angle spinning (MAS) solid-state NMR (ssNMR) spectroscopy is emerging as a unique method for the atomic resolution structure determination of native membrane proteins in lipid bilayers. Although 13C-detected ssNMR experiments continue to play a major role, recent technological developments have made it possible to carry out 1H-detected experiments, boosting both sensitivity and resolution. Here, we describe a new set of 1H-detected hybrid pulse sequences that combine through-bond and through-space correlation elements into single experiments, enabling the simultaneous detection of rigid and dynamic domains of membrane proteins. As proof-of-principle, we applied these new pulse sequences to the membrane protein phospholamban (PLN) reconstituted in lipid bilayers under moderate MAS conditions. The cross-polarization (CP) based elements enabled the detection of the relatively immobile residues of PLN in the transmembrane domain using through-space correlations; whereas the most dynamic region, which is in equilibrium between folded and unfolded states, was mapped by through-bond INEPT based elements. These new 1H-detected experiments will enable one to detect not only the most populated (ground) states of biomacromolecules, but also sparsely populated high-energy (excited) states for a complete characterization of protein free energy landscapes. PMID- 29173804 TI - Coagulation profile following liver resection: Does liver cirrhosis affect thromboelastography? AB - BACKGROUND: Thromboelastography has called into question the coagulopathy seen following partial hepatectomy. However the coagulation profile in cirrhotic livers has not been studied. Our objective was to determine the coagulation profile following partial hepatectomy in normal and cirrhotic livers. METHODS: Patients undergoing liver resection were prospectively enrolled in the study. The prothrombin time and international normalized ratio, as well as the thromboelastogram, were obtained preoperatively, post-operatively, and on post operative days 1, 3, and 5. RESULTS: 22 noncirrhotic and 11 cirrhotic patients undergoing liver resection were enrolled. Postoperatively the thromboelastogram demonstrated a hypercoagulable profile in 64%, 33%, 39% and 36% of patients on post-operative days 0, 1, 3 and 5 respectively. There was no difference between patients with cirrhosis and those without underlying liver disease. CONCLUSION: Patients appear to have a similar coagulation profile after liver resection regardless of underlying cirrhosis with many having a hypercoagulable profile. PMID- 29173805 TI - Cardiac Amyloidosis: An Updated Review With Emphasis on Diagnosis and Future Directions. AB - Cardiac amyloidosis occurs because of abnormal protein (amyloid) deposition in the cardiac tissue. Even with advanced diagnostic techniques and treatments, the prognosis of amyloidosis remains poor. The diagnosis of cardiac amyloidosis particularly needs to be in the differential in patients presenting with heart failure with preserved ejection fraction. This entity remains underdiagnosed due to lack of suspicion on the part of many clinicians. Involvement of cardiac tissue is the utmost determinant factor for available treatment options and prognosis. Many cases of cardiac amyloidosis usually remain undiagnosed or diagnosed only in advanced stages when treatment options are limited and associated with poor survival. Hence, early recognition of cardiac amyloidosis is indispensable in halting the disease process before irreversible changes occur. The purpose of this review is to summarize the recent updates in the evaluation and management of cardiac amyloidosis and to discuss potential future treatments options.

PMID- 29173807 TI - Association between hemostatic markers, serum lipid fractions and progression of cerebral small vessel disease: A 2-year follow-up study. AB - INTRODUCTION: Little is known if hemostatic markers and serum lipid fractions can predict further radiological progression beyond vascular risk factors in cerebral small vessel disease (SVD). We investigated whether they are associated with SVD radiological progression and if they are related to different SVD clinical manifestations. METHODS: A single-center, prospective, cohort study with 2 years of radiological follow-up was performed in consecutive patients with different SVD manifestations. The study group consisted of 123 patients: 49 with lacunar stroke (LS), 48 with vascular dementia (VaD) and 26 with vascular parkinsonism (VaP). We assessed SVD progression by a visual SVD scale. We determined the relationship between serum or plasma concentrations of tissue factor (TF), thrombomodulin, beta-thromboglobulin (BTG), fibrinogen, D-dimer and total cholesterol, HDL-C, LDL-C, triglycerides and SVD progression by logistic regression analysis. RESULTS: 34.9% patients had SVD radiological progression: 43% had isolated WMLs progression, 23.2% had new lacunes, 34.8% had both WMLs progression and new lacunes. Fibrinogen [OR 1.02 (95% CI 1.006-1.011] was significantly associated with risk of new lacunes or WMLs progression regardless of the clinical SVD manifestation. While low HDL [OR 0.96 (0.93-1)] and TF [OR 1.07 (0.99-1.1)] were marginally associated with new lacunes, BTG [OR 1.005 (0.99 1.01)] was associated with WMLs progression. CONCLUSION: We found a relationship between fibrinogen and risk of radiological progression of SVD regardless of the clinical SVD manifestation. In addition, lower HDL and increased TF predicted development of new lacunes, and higher BTG was associated with risk of WMLs progression.

AB - Aplastic anemia or bone marrow failure often develops as an effect of chemotherapeutic drug application for the treatment of various pathophysiological conditions including cancer. The long-term bone marrow injury affects the basic hematopoietic population including hematopoietic stem/progenitor cells (HSPCs). The present study aimed in unearthing the underlying mechanisms of chemotherapeutics mediated bone marrow aplasia with special focus on altered redox status and associated effects on hematopoietic microenvironment and epigenetic status of hematopoietic cells. The study involves the development of busulfan and cyclophosphamide mediated mouse model for aplastic anemia, characterization of the disease with blood and marrow analysis, cytochemical examinations of bone marrow, flowcytometric analysis of hematopoietic population and microenvironmental components, determination of ROS generation, apoptosis profiling, expressional studies of Notch-1 signaling cascade molecules, investigation of epigenetic modifications including global CpG methylation of DNA, phosphorylation of histone-3 with their effects on bone marrow kinetics and expressional analysis of the anti-oxidative molecules viz; SOD-2 and Sdf-1. Severe hematopoietic catastrophic condition was observed during aplastic anemia which involved peripheral blood pancytopenia, marrow hypocellularity and decreased hematopoietic stem/progenitor population. Generation of ROS was found to play a central role in the cellular devastation in aplastic marrow which on one hand can be correlated with the destruction of hematopoiesis supportive niche components and alteration of vital Notch-1 signaling and on other hand was found to be associated with the epigenetic chromatin modifications viz; global DNA CpG hypo-methylation, histone-3 phosphorylation promoting cellular apoptosis. Decline of anti-oxidant components viz; Sdf-1 and SOD-2 hinted towards the irreversible nature of the oxidative damage during marrow aplasia. Collectively, the findings hinted towards the mechanistic correlation among ROS generation, microenvironmental impairment and epigenetic alterations that led to hematopoietic catastrophe under aplastic stress. The findings may potentiate successful therapeutic strategy development for the dreadful condition concerned. PMID- 29173809 TI - The feasibility study of 177Lu production in Miniature Neutron Source Reactors using a multi-stage approach in Isfahan, Iran. AB - Miniature neutron source reactors (MNSRs) are among the safest and economic research reactors with potentials to be used for neutron studies. This manuscript explores the feasibility of 177Lu production in Isfahan MNSR reactor using direct production route. In this study, to assess the specific activity of the produced radioisotope, a simulation was carried out through the MCNPX2.6 code. The simulation was validated by irradiating a lutetium disc-like (99.98 chemical purity) at the thermal neutron flux of 5 * 1011 ncm2s-1 and an irradiation time of 4min. After the spectrometry of the irradiated sample, the experimental results of 177Lu production were compared with the simulation results. In addition, factor from the simulation was extracted by replacing it in the related equations in order to calculate specific activity through a multi-stage approach, and by using different irradiation techniques. The results showed that the simulation technique designed in this study is in agreement with the experimental approach (with a difference of approximately 3%). It was also found that the maximum 177Lu production at the maximum flux and irradiation time allows access to 723.5mCi/g after 27 cycles. Furthermore, the comparison of irradiation techniques showed that increasing the irradiation time is more effective in 177Lu production efficiency than increasing the number of irradiation cycles. In a way that increasing the irradiation time would postpone the saturation of the productions. On the other hand, it was shown that the choice of an appropriate irradiation technique for 177Lu production can be economically important in term of the effective fuel consumption in the reactor.

AB - This paper presents a Monte Carlo method to obtain the full energy peak efficiency (FEPE) curve for a High Purity Germanium (HPGe) detector, as it is difficult and time-consuming to measure the FEPE curve experimentally. The Geant4 simulation toolkit was adopted to establish a detector model since detector specifications provided by the nominal manufacturer are usually insufficient to calculate the accurate efficiency of a detector. Several detector parameters were optimized. FEPE curves for a given HPGe detectors over the energy range of 59.50 1836keV were obtained and showed good agreements with those measured experimentally. FEPE dependences on detector parameters and source-detector distances were investigated. A best agreement with experimental result was achieved for a certain detector geometry and source-detector distance.

AB - In this paper, a preliminary neutronic design study of an accelerator driven subcritical system for Jordan Subcritical Assembly (JSA) is presented. The conceptual design of coupling the JSA core with proton accelerator and spallation target is investigated, and its feasibility as a neutron source for nuclear research, and possibly for target irradiation and isotope production evaluated. 3D MCNPX model of the JSA reactor, the accelerator beam, and the Pb target was developed, based on actual reactor parameters. MCNPX calculations were carried out to estimate the absolute radial and axial neutron flux in the reactor, and to calculate the multiplication factor Keff and heat generated in the reactor. Numerical results showed an enormous increase in the neutron flux, by seven orders of magnitude, compared to the current JSA core design using Pu-Be source. In this research the results obtained are discussed and compared with those of the JSA, and do confirm the feasibility of utilizing the JSA as a viable nuclear research facility with adequate neutron flux.

AB - The Korea Research Institute of Standards and Science (KRISS) participated, in 2015, in an international Key Comparison (KC) of gaseous radon-222 activity named CCRI (II) -K2.Rn-222 to confirm international equivalence of KRISS-established gaseous radon-222 measurement standards. LNHB acted as KC pilot laboratory. This paper describes the KC measurement procedure followed at KRISS using the defined solid angle counting method together with auxiliary relative measurement methods and presents the results. PMID- 29173813 TI - An approach to derive some simple empirical equations to calibrate nuclear and acoustic well logging tools. AB - A set of three pads was constructed from primary materials (sand, gravel and cement) to calibrate the gamma-gamma density tool. A simple equation was devised to convert the qualitative cps values to quantitative g/cc values. The neutron neutron porosity tool measures the qualitative cps porosity values. A direct equation was derived to calculate the porosity percentage from the cps porosity values. Cement-bond log illustrates the cement quantities, which surround well pipes. This log needs a difficult process due to the existence of various parameters, such as: drilling well diameter as well as internal diameter, thickness and type of well pipes. An equation was invented to calculate the cement percentage at standard conditions. This equation can be modified according to varying conditions.

AB - Absorbed doses to human organs from 188Re-Rituximab in the free form and bound to superparamagnetic iron oxide nanoparticles were predicted from results of the radiopharmaceutical biodistribution studies in mice by the RADAR method. Overall, equivalent and effective doses to human organs from the radiopharmaceutical on the nanoparticles were higher because of the enhanced permeability and retention effect. Liver, spleen and kidneys received higher equivalent doses than other organs (5.29, 3.70 and 3.06mSv/MBq, respectively, for the free radiopharmaceutical and 6.12, 3.96 and 3.93mSv/MBq for the drug on the nanoparticles). PMID- 29173815 TI - [Focusing on kidney transplantation in the elderly]. AB - Due to the increase in life expectancy and the ageing of end-stage renal disease patients, the number of patients older than 65 years receiving a kidney transplant has been continuously growing over the last fifteen years. The benefits of renal transplantation compared to dialysis in terms of survival and quality of life have been shown in selected recipients over 65, or 70 years. However, the age remains the main limiting factor for the access to the waiting list, and the reluctance of the clinicians can be explained by the multiple comorbidities of these candidates, their limited life expectancy or the shortage of grafts. The challenge is to select the candidates who can benefit from renal transplantation, thanks to rigorous cardiovascular and neoplastic evaluation before enrolment and by taking into account the specific characteristics of elderly patients. The living donor appears to be the ideal option for elderly recipients, the alternative being the extended criteria donor, allowing waiting times to be limited. The choice of immunosuppressive therapy is also crucial in these patients at high risk of infectious and cardiovascular complications in whom the occurrence of acute rejection can have severe consequences. There are currently no specific recommendations for immunosuppression in elderly recipients, and we would need large-scale randomized studies to improve the prognosis of renal transplantation in this population. PMID- 29173816 TI - The Prediction of Body Composition in African Americans From Spine and Hip Dual Energy Absorptiometry. AB - Body composition, the makeup of the body's fat and lean tissue, is associated with important health outcomes and provides useful clinical information. Although body composition can be measured with total body dual-energy X-ray absorptiometry (DXA), this is rarely performed. As an alternative to total body DXA measurement, methods for estimation of body composition have been developed. These methods use soft tissue measures from spine and hip DXA to predict body composition and include prediction equations previously published by Leslie and proprietary equations within General Electric densitometry software. However, these estimates have not been tested in African Americans (AA), an ethnicity with a different distribution of fat than Caucasians (CA). Therefore, we examined the performance of the existing models in 99 CA and 162 AA subjects over the age of 40 who had total body, spine, and hip DXA measurements. We observed that existing models estimated body composition well in CA but underestimated fat mass and overestimated lean mass in AA. AA subjects were then randomly divided into 2 equal-sized subgroups-the first to develop new prediction equations and the second to independently validate them. We found that body composition can be more accurately estimated using either a new model that we derived in AA subjects using backward stepwise elimination or by adding a fixed offset for AA to the previously published model. Our results demonstrate that body composition estimates from spine and hip DXA require consideration of race/ethnicity. PMID- 29173817 TI - Adaptive Bone Remodeling With New Design of the ABG Stem. Densitometric Study. AB - To establish the pattern of bone remodeling caused by a cementless, anatomic implant, we intend to evaluate the changes in bone mineral density observed after surgery in the Gruen zones. A controlled, prospective study was carried out, in which a group of 37 patients with primary coxarthrosis were densitrometrically analyzed over the 1 year period following the implant of an ANATO stem (Stryker). The patient's healthy hip was taken as the control. Any differences in the remodeling pattern were compared according to age, body mass index, and implant size. Decreases in bone mineral density were observed after 3 months in all of the zones studied. However, this bone mineral density loss was recovered in all zones by the end of the study, except in zone 7 where a decrease of 7.2% in bone mass was observed. In zones 2 and 6, where more loads are transmitted, bone mass preservation, in accordance with Wolff's law, can be seen. No differences were found in the remodeling pattern in relation to age and body mass index. There were also no differences related to stem size except in zones 1 and 7. The ANATO stem achieves an efficient transmission of loads between the stem and the proximal femur, providing enough mechanical loads for bone preservation. It is only in zone 7 where significant bone atrophy can be observed, attributable to the damage that this area suffers during the surgical process and the subsequent stress-shielding caused by the implant design.

PMID- 29173820 TI - ORP-Mediated ER Contact with Endocytic Sites Facilitates Actin Polymerization. AB - Oxysterol binding protein-related proteins (ORPs) are conserved lipid binding polypeptides, enriched at ER contacts sites. ORPs promote non-vesicular lipid transport and work as lipid sensors in the context of many cellular tasks, but the determinants of their distinct localization and function are not understood. Here, we demonstrate that the yeast endocytic invaginations associate with the ER and that this association specifically requires the ORPs Osh2 and Osh3, which bridge the endocytic myosin-I Myo5 to the ER integral-membrane VAMP-associated protein (VAP) Scs2. Disruption of the ER contact with endocytic sites using ORP, VAP, myosin-I, or reticulon mutants delays and weakens actin polymerization and interferes with vesicle scission. Finally, we provide evidence suggesting that ORP-dependent sterol transfer facilitates actin polymerization at endocytic sites. PMID- 29173819 TI - Bleb Expansion in Migrating Cells Depends on Supply of Membrane from Cell Surface Invaginations. AB - Cell migration is essential for morphogenesis, organ formation, and homeostasis, with relevance for clinical conditions. The migration of primordial germ cells (PGCs) is a useful model for studying this process in the context of the developing embryo. Zebrafish PGC migration depends on the formation of cellular protrusions in form of blebs, a type of protrusion found in various cell types. Here we report on the mechanisms allowing the inflation of the membrane during bleb formation. We show that the rapid expansion of the protrusion depends on membrane invaginations that are localized preferentially at the cell front. The formation of these invaginations requires the function of Cdc42, and their unfolding allows bleb inflation and dynamic cell-shape changes performed by migrating cells. Inhibiting the formation and release of the invaginations strongly interfered with bleb formation, cell motility, and the ability of the cells to reach their target. PMID- 29173821 TI - Assessment of quality of life in patients surgically treated for penile cancer: Impact of aggressiveness in surgery. AB - PURPOSE: Health-related quality of life (HRQoL) evaluations are being increasingly used for clinical assessment of cancer treatment outcomes. For a patient, not only is life expectancy important, but also a general sense of sustained global health. Intuitively, the more disfiguring the treatment, the more pronounced could be the deterioration in the QoL. We aimed to compare various aspects of QoL in three groups of patients surgically treated for penile cancer by local excision, partial penectomy, or total penectomy. METHODS: HRQoL was assessed in 51 patients surgically treated for penile cancer. Total penectomy, partial penectomy, or wide local excision was performed in 11, 27, and 13 patients, respectively. The EORTC QLQ-C30 questionnaire was used for HRQoL assessment. Relations between the patients and their partners were also assessed. RESULTS: Statistically significant negative correlation was found between aggressiveness of the surgical procedure and both, assessment of global health status (p = 0.04) and physical functioning (p = 0.047). The more aggressive the surgery, the lower was the patients' assessment of their QoL. Among the patients who maintained their partner relations postsurgery, 58.9% declared that their relations postoperatively were not inferior compared to those preoperatively. There was no statistically significant effect of the surgery type on relations with female partners (p = 0.619). CONCLUSION: The magnitude of disfigurement caused by surgical treatment of penile cancer had a significant impact on the selected QoL domains assessed by the EORTC QLQ C-30 questionnaire. There was no correlation between the scope of surgical intervention and partner relations. PMID- 29173822 TI - The effectiveness of a clinical and home-based physical activity program and simple lymphatic drainage in the prevention of breast cancer-related lymphedema: A prospective randomized controlled study. AB - PURPOSE: To investigate the effectiveness of a clinical and home-based, nurse-led physical activity program (PAP) and simple lymphatic drainage (SLD) in the prevention of breast cancer-related lymphedema. METHODS: A total of 52 breast cancer patients were randomized to either a PAP and SLD program (n = 25) or a control group (n = 27). Patients in both groups were also provided training for lymphedema. The PAP and SLD were administered through home visits by the investigators, twice a week for six weeks, in the intervention group. The control group did not undergo intervention. The circumference of the upper extremity, symptom severity, and physical function were measured in both groups. RESULTS: The upper extremity circumference increased by about two times from the baseline, in the control group, especially in the sixth week (p < 0.05). Lymphedema-related symptom severity scores were found to decrease significantly in the intervention group, compared to those at the baseline (p < 0.05). CONCLUSION: It was recommended that PAP and SLD, with a follow-up program, be used for patients who planned to undergo breast cancer surgery, starting from before surgery and continuing until after, to prevent breast cancer-related lymphedema. PMID- 29173823 TI - Barriers and facilitators of cervical cancer screening practices among African immigrant women living in Brisbane, Australia. AB - PURPOSE: To describe barriers and facilitators of cervical screening practices among African immigrant women living in Brisbane, Australia. METHOD: Nineteen African immigrant women (10 refugee and 9 non-refugee) were recruited using convenience sampling. The interviews were conducted with a semi-structured and open-ended questionnaire guide. All the interviews were audio recorded and transcribed verbatim. The data was manually analysed using interpretative thematic analysis. Thematic categories were identified and organised into coherent broader areas. RESULTS: Lack of knowledge about cervical cancer and Pap smear, the absence of warning signs, embarrassment, fear, concern about the gender of the service provider, lack of privacy, cultural and religious beliefs, and healthcare system factors were identified as barriers to screening. The results did not show any major differences between refugee and non-refugee women. Recommendation of the test by health professionals, provision of standardised information on the test, and preferences for female service providers were identified as facilitators of cervical screening. CONCLUSION: There is a need to provide culturally appropriate approaches to cervical screening practices and to enhance cultural competence among health professionals to apply service delivery models that honour group cultures. PMID- 29173824 TI - From vulnerability to passion in the end-of-life care: The lived experience of nurses. AB - PURPOSE: End-of-life (EOL) care is considered to be inherently difficult and vulnerable for patients and nurses. It also seems hard to develop passion for care during these problematic times. This study elucidates how EOL nurses interpret their care experience and how they transform their experience and mindset. METHODS: This study was conducted by organizing a reflective group based on the concept of group analysis for oncology and hospice nurses to share their experience. Thirteen registered nurses were enrolled from a medical center in northern Taiwan. Data drawn from the group dialogue was derived from six digitally recorded sessions and then analysed alone with the researcher's diaries and participants' feedback sheets. Interpretative Phenomenological Analysis (IPA) was used to analyze the data. RESULTS: The results showed that nurses who provide EOL care actually experience suffering by witnessing patients' suffering. However, the suffering authentically drives the nurses to encounter their own inner selves, to induce the shift of mindset, and then allow them to continuously provide and maintain the passion in EOL care. CONCLUSIONS: This study provides a new viewpoint for understanding of EOL nurses' experiences, indicating that this line of work may be recognized as a privilege. We recommend that the setting of a nurse reflective group is important and it may be considered in providing EOL care training for nurses. Hopefully the study results could shed lights for future policies regarding EOL care. PMID- 29173825 TI - Use of a symptom diary during chemotherapy: A mixed-methods evaluation of the patient perspective. AB - PURPOSE/OBJECTIVES: Patients' perceptions about tools for self-reporting symptoms experienced at home may influence both the patients' use of the tool and ultimately the efficacy of the interventions. The aim of this study was to determine the extent patients use a paper-pencil symptom-monitoring diary during chemotherapy treatment, to identify factors that mediate its use at home, and to determine perceptions patients have of the diary. METHODS: A quantitative survey assessed patients' use of the diary, their experiences and opinions. A secondary analysis of semi-structured interviews used was performed to determine how patients perceived being offered the diary for tracking symptoms and, if they did use it, their experiences with the diary. RESULTS: Eighty-seven patients (78%) used or had been using the diary during their chemotherapy treatment. Most patients felt that the diary supported them in discussing treatment-related symptoms with their doctors and nurses during hospital visits and helped them to deal with symptoms at home. However, diary users felt that their professional caregivers viewed the diary differently, specifically not valuing it enough to actively use it in their care. CONCLUSIONS: This study indicates that the majority of chemotherapy patients at our hospital perceive the symptom diary to be a feasible tool in terms of ease of use and time investment and that it is helpful. However, from the patient perspective, healthcare professionals' implementation of the diary in their behalf is lacking. PMID- 29173826 TI - Effect of an intervention based on basic Buddhist principles on the spiritual well-being of patients with terminal cancer. AB - PURPOSE: To evaluate the effect of an intervention based on basic Buddhist principles on the spiritual well-being of patients with terminal cancer. METHODS: This quasi-experimental research study had pre- and post-test control groups. The experimental group received conventional care and an intervention based on basic Buddhist principles for three consecutive days, including seven activities based on precept activities, concentration activities and wisdom activities. The control group received conventional care alone. RESULTS: Forty-eight patients participated in this study: 23 in the experimental group and 25 in the control group. Their mean age was 53 (standard deviation 10) years. The spiritual well being of participants in the experimental group was significantly higher than that of participants in the control group at the second post-test (P < 0.05). CONCLUSIONS: An intervention based on basic Buddhist principles improved the spiritual well-being of patients with terminal cancer. This result supports the beneficial effects of implementing this type of intervention for patients with terminal cancer. PMID- 29173827 TI - Hoping to reach a safe haven - Swedish families' lived experience when a family member is diagnosed with breast cancer. AB - PURPOSE: When a woman is diagnosed with breast cancer, it affects all family members. Therefore, the aim of this study was to elucidate family members lived experience when a family member is diagnosed with breast cancer. METHOD: The study had a hermeneutic phenomenological design including individual conversational interviews conducted face-to-face with six women with breast cancer and their family members at two different points of time, in order to elucidate families' lived experience, both as individuals and as a unit, from each family member's perspective. RESULTS: Living as a family in the presence of breast cancer is a challenging endeavour to regain an ordinary, safe life, hoping to reach a safe haven. The families felt that life as they knew it had disappeared and they were fumbling in the dark, trying to find support and guidance on their path to ordinary life. The family members were pursuing balance by attempting to keep the family together and maintaining a positive attitude while battling against fear and treatment-related side effects. Finally, the families were struggling with guilt and inadequacy, due to their difficulties in communicating the emotional distress that the illness brought upon them, at the same time as they felt abandoned by the healthcare professionals. CONCLUSIONS: Families experience an unmet need of information and support, which implies that healthcare professionals may want to acknowledge and include the family already at the time of diagnosis in order to help them endure and cope with the distressing experience and thus increase their wellbeing. PMID- 29173828 TI - Employing patient-reported outcome (PRO) measures to support newly diagnosed patients with melanoma: Feasibility and acceptability of a holistic needs assessment intervention. AB - PURPOSE: Living with a melanoma diagnosis can be challenging. We aimed to assess the feasibility, acceptability, and perceived value of a nurse-led intervention that utilised patient-reported outcome (PRO) measures to identify and address the supportive care needs of newly diagnosed patients with Stage I/II melanoma over the first 4 months post-diagnosis. METHODS: We conducted an exploratory, repeated measures, single-arm, feasibility trial. One baseline (4 weeks post-diagnosis; T1) and one follow-up intervention session (4 weeks after wide local excision; T3) took place, two months apart. Patient survey data were collected monthly, at four assessment points (T1-T4), followed by exit interviews. RESULTS: A recruitment rate of 55% (10/18) was achieved. The skin cancer nurse specialist (CNS) performed 19 in-clinic patient assessments within 6 months. One patient missed their follow-up intervention session (90% retention rate). Three participants (30%) were lost to follow-up at T4. Patients endorsed the standardised use of easy-to-use PRO measures as a means to help them shortlist, report and prioritise their needs. The CNS viewed the intervention as a highly structured activity that allowed tailoring support priority needs. A sizeable reduction in information needs was found from T1 to T4 (Standardised Response Mean [SRM] change = -0.99; p < 0.05). From T1 to T2, significant reductions in psychological (SRM change = -1.18; p < 0.001), practical (SRM change = -0.67; p < 0.05) and sexuality needs (SRM change = -0.78; p < 0.05) were observed. CONCLUSIONS: The intervention appears to be feasible in clinical practice and acceptable to both patients with newly diagnosed melanoma and clinicians. Future research is warranted to test its effectiveness against standard care. PMID- 29173829 TI - Recruiting participants to a randomized controlled trial testing an intervention in palliative cancer care - The perspectives of health care professionals. AB - PURPOSE: The recruitment of participants to randomized controlled trials (RCTs) in palliative cancer care by health care professionals is often unsuccessful, which could result in failure to achieve study power. The purpose of this paper is to describe how health care professionals experienced recruiting patients and family caregivers to an RCT in palliative cancer care. METHODS: The study had a qualitative explorative design. Ten palliative home care settings were involved in the RCT and data were generated through focus group discussions and interviews with health care professionals who were responsible for the recruitment. The transcripts were analyzed with interpretive descriptive principles. RESULTS: The experiences of the health care professionals reveal that communicating the RCT design to patients and family caregivers was a challenging part of the recruitment but was considered a process of learning over time. The delicate situation that participants were living under added to the challenge and health care professionals believed that the randomized design was contrary to their normal approach to always offer the best possible support. CONCLUSIONS: The results contribute valuable knowledge for future trials in palliative cancer care. To promote successful recruitment, health care professionals may be in need of more training to improve their communication skills and it may be necessary to consider other research designs than the RCT. PMID- 29173830 TI - The lived experiences of patients with post-operative rectal cancer who suffer from altered bowel function: A phenomenological study. AB - PURPOSE: Altered bowel function is a common consequence of anal sphincter-saving surgery in rectal cancer patients, and bowel symptoms influence patients' daily life and psychosocial status. Patients have inadequate professional support because care specialists fail do fully appreciate the impact of the patients' symptoms. In-depth exploration of the individual's experience is essential to improve the quality of patient care. The purpose of this study was to explore the lived experiences of post-operative rectal cancer patients with altered bowel function. METHODS: This Husserlian descriptive phenomenological study recruited 16 post-operative rectal cancer patients with altered bowel function. Data was collected through purposive sampling and one-on-one in-depth, semi-structured interviews. Narratives were analyzed thematically using Colaizzi's seven-step method. RESULTS: Three themes emerged, namely: "living in the restroom", "never backward", and "rebalancing on a new road". "Living in the restroom" described how patients frequent the restroom due to post-operative physical changes. "Never backward" outlined that such changes disturbed their mood, interrupted their daily activities, and affected their family life. "Rebalancing on a new road" described the patients' coping strategies, which included spiritual reconstruction, a new excrement model, an adjusted lifestyle, and peer support. CONCLUSIONS: Post-operative rectal cancer patients with altered bowel function frequent the restroom for prolonged periods, which disturbs their psychosocial status. However, they are forced to develop coping methods by themselves. Specialists can offer effective early post-operative interventions by thoroughly understanding each patient's symptomatic experience, symptom-related interferences, and primary concerns. PMID- 29173831 TI - An exploration of medical emergency team intervention at the end of life for people with advanced cancer. AB - PURPOSE: Recent advances in cancer therapies offer survival benefit when cure is no longer possible. The contribution of the Medical Emergency Teams (METs) in the context of advancing disease has received little empirical consideration. This study set out to explore MET intervention at the end of life for people with advanced cancer in an Australian comprehensive cancer centre, and its impact on quality of death. METHOD: A retrospective medical chart review was undertaken to explore MET response for people with advanced (incurable) cancer nearing end of life. Occurrence of MET interventions at the end of life and a quality of death score were recorded for two randomly selected cohorts of patients, those who experienced a MET response within their last week of life (n = 50) and those who did not (n = 50). RESULTS: The cohort who did not receive MET intervention had a significantly higher (better) quality of death score when compared with patients who did receive a MET intervention (p = 0.01). Within the cohort who received a MET intervention, a subgroup (n = 19) where the MET influenced end-of-life decision-making had a significantly higher quality of death score (p = 0.02) than patients in the MET cohort (n = 31) where the MET did not influence end-of-life care. CONCLUSION: The contribution of the MET to end-of-life care for patients with cancer has not previously been reported. Further research is now needed to prospectively examine MET involvement at the end of life with consideration to quality of patient care and death, family experience, and support requirements of MET members. PMID- 29173832 TI - The psychometric properties of the Turkish version of the Chemotherapy-Induced Peripheral Neuropathy Assessment Tool (CIPNAT). AB - PURPOSE: Chemotherapy-induced peripheral neuropathy is a common treatment-related adverse effect. It adversely affects the quality of life. Therefore, it is important to evaluate symptoms. The purpose of this study was to evaluate the validity and reliability of Chemotherapy-Induced Peripheral Neuropathy Assessment Tool in Turkish patients. METHODS: A convenience sample of 327 patients, being treated with peripheral neurotoxic chemotherapeutic agents were asked to fill in the questionnaire. The data was evaluated using SPSS 21 (SPSS Inc., Chicago IL, USA) statistical software. The verification of the structure obtained with CFA was provided by AMOS 21.0. Psychometric testing included internal consistency reliability (Cronbach's alpha coefficient and item-total correlations), test retest reliability, validity (exploratory factor analysis, confirmatory factor analysis and concurrent validity). RESULTS: The Cronbach alpha value of the scale was 0.97. The test-retest reliability results were significantly high. The CIPNAT significantly correlated with the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Chemotherapy-Induced Peripheral Neuropathy. The model was validated by confirmatory factor analysis (chi2/sd = 2.74, GFI = 0.95, AGFI = 0.92, CFI = 0.98, RMSEA = 0.07, and RMR = 0.009). CONCLUSIONS: The Turkish version of the CINAT was found to be reliable and valid with Turkish patients receiving chemotherapy. Use of the CIPNAT may lead to a better understanding of symptom. The CIPNAT can be used in future nursing research and practice as an assessment tool for peripheral neuropathy in patients with cancer who undergo chemotherapy.

AB - PURPOSE: This descriptive cross-sectional study aimed to determine the impact of parental depression level on children's quality of life after haematopoietic stem cell transplantation (HSCT). METHOD: This study was conducted in a bone marrow transplantation unit of a children's hospital in Ankara, Turkey. The research sample consisted of 82 parents. Children aged 2-18 years and monitored in polyclinics 100 days after HSCT were included in the study. A sociodemographic data form, parent forms of the Pediatric Quality of Life Inventory, and the Beck Depression Inventory (BDI) were used. RESULTS: Forty (48%) mothers and 42 (51.2%) fathers participated in the study. Of the children, 30 (36.6%) were female and 52 (63.4%) were male, and their mean age was 10.68 [standard deviation (SD) 4.80] years. Twenty-six children (31.7%) had been diagnosed with thalassaemia, and 29 children (35.4%) had undergone HSCT in the previous 25-36 months. The mean total scale score on the Pediatric Quality of Life Inventory was 61.37 (SD 21.85), and the mean parental BDI Score was 14.57 (SD 11.03). Fourteen (17.1%) parents had severe depression and 10 (12.2%) parents had moderate depression. Low statistical correlation was found between the parental BDI score and the total scale score on the Pediatric Quality of Life (r = -0.281; P = 0.011). CONCLUSION: Parental depression level affects children's quality of life after HSCT. Following transplantation, it is important to evaluate parental depression level and provide support.

AB - The Academy of Nutrition and Dietetics (Academy) is the world's largest organization of food and nutrition professionals and the association that represents credentialed nutrition and dietetics practitioners-registered dietitian nutritionists (RDNs) and nutrition and dietetics technicians, registered (NDTRs). RDNs integrate research, professional development, and practice to stimulate innovation and discovery; collaborate to solve the greatest food and nutrition challenges now and in the future; focus on systemswide impact across the food, wellness, and health sectors; have a global impact in eliminating all forms of malnutrition; and amplify the contribution of nutrition and dietetics practitioners and expand workforce capacity and capability. The Revised 2017 Scope of Practice for the RDN reflects the position of the Academy on the essential role of the RDN in the direction and delivery of food and nutrition services. The scope of practice for the RDN is composed of education and credentialing, practice resources, Academy Standards of Practice and Professional Performance, codes of ethics, accreditation standards, state and federal regulations, national guidelines, and organizational policy and procedures. The Revised 2017 Scope of Practice for the RDN is used in conjunction with the Revised 2017 Standards of Practice (SOP) in Nutrition Care and the Standards of Professional Performance (SOPP) for RDNs. The SOP address activities related to direct patient and client care. The SOPP address behaviors related to the professional role of RDNs. These standards reflect the minimum competent level of nutrition and dietetics practice and professional performance for RDNs. A companion document addresses the scope of practice for the NDTR. PMID- 29173835 TI - Academy of Nutrition and Dietetics: Revised 2017 Standards of Practice in Nutrition Care and Standards of Professional Performance for Registered Dietitian Nutritionists. AB - Registered dietitian nutritionists (RDNs) face complex situations every day. Competently addressing the unique needs of each situation and applying standards appropriately are essential to providing safe, timely, patient-/client-/customer centered, quality nutrition and dietetics care and services. The Academy of Nutrition and Dietetics (Academy) leads the profession by developing standards that can be used by RDNs (who are credentialed by the Commission on Dietetic Registration) for self-evaluation to assess quality of practice and performance. The Standards of Practice reflect the Nutrition Care Process and workflow elements as a method to manage nutrition care activities with patients/clients/populations that include nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention/plan of care, nutrition monitoring and evaluation, and discharge planning and transitions of care. The Standards of Professional Performance consist of six domains of professional performance: Quality in Practice, Competence and Accountability, Provision of Services, Application of Research, Communication and Application of Knowledge, and Utilization and Management of Resources. Within each standard, specific indicators provide measurable action statements that illustrate how the standard can be applied to practice. The Academy's Revised 2017 Standards of Practice and Standards of Professional Performance for RDNs, along with the Academy's Code of Ethics and the Revised 2017 Scope of Practice for the RDN, provide minimum standards and tools for demonstrating competence and safe practice and are used collectively to gauge and guide an RDN's performance in nutrition and dietetics practice.

AB - OBJECTIVE: We assessed emergency department (ED) patient perceptions of how physicians can improve their language to determine patient preferences for 11 phrases to enhance physician empathy toward the goal of reducing low-value advanced imaging. METHODS: Multi-center survey study of low-risk ED patients undergoing computerized tomography (CT) scanning. RESULTS: We enroled 305 participants across nine sites. The statement "I have carefully considered what you told me about what brought you here today" was most frequently rated as important (88%). The statement "I have thought about the cost of your medical care to you today" was least frequently rated as important (59%). Participants preferred statements indicating physicians had considered their "vital signs and physical examination" (86%), "past medical history" (84%), and "what prior research tells me about your condition" (79%). Participants also valued statements conveying risks of testing, including potential kidney injury (78%) and radiation (77%). CONCLUSION: The majority of phrases were identified as important. Participants preferred statements conveying cognitive reassurance, medical knowledge and risks of testing. PRACTICE IMPLICATIONS: Our findings suggest specific phrases have the potential to enhance ED patient perceptions of physician empathy. Further research is needed to determine whether statements to convey empathy affect diagnostic testing rates.

PMID- 29173854 TI - Alignment efficiency and esthetic performance of 4 coated nickel-titanium archwires in orthodontic patients over 8 weeks: A multicenter randomized clinical trial. AB - INTRODUCTION: The objective of this 4-arm parallel study was to evaluate the alignment efficiency and esthetic performance of 4 coated nickel-titanium archwires over an 8-week period. METHODS: Patients in the permanent dentition requiring maxillary and mandibular fixed orthodontic treatment with a preadjusted edgewise appliance were eligible for inclusion. Patients attending 4 hospital departments (United Kingdom and Italy) were randomly allocated to 1 of 4 treatment interventions: (1) BioCosmetic (Forestadent, Pforzheim, Germany), 0.017 in; (2) Titanol (Forestadent), 0.016 in; (3) TP Aesthetic (TP Orthodontics, La Porte, Ind), 0.014 in; and (4) Tooth Tone (Ortho Organizers, Calsbad, Calif) 0.016 in. Block randomization with block sizes of 4 and 8 was used to ensure an allocation ratio of 1:1:1:1. The primary outcome was alignment efficiency determined by the reduction in Little's irregularity index (mm). Secondary outcomes were color change using the Commission Internationale de L'Eclairage L*a*b* system and percentage of coating loss. Blinding was only applicable to outcome assessment of alignment efficiency. Regression models with Sidak's multiple comparison of means were used to analyze the data. RESULTS: One hundred fifty patients (300 dental arches) were allocated to the treatment interventions, including 61 male and 89 female subjects with a mean age of 16.60 years. The average duration of follow-up was 63.65 days. Baseline characteristics for the archwire groups were similar. One patient was lost to follow-up. Five percent (n = 15) of the archwires fractured: BioCosmetic, 5.3% (n = 4); Titanol, 6.8% (n = 5); TP Aesthetic, 5.3% (n = 4); and Tooth Tone, 2.7% (n = 2). We analyzed 283 dental arches for alignment efficiency. There was no statistically significant difference for mean reduction in irregularity between the archwire groups (P = 0.627): BioCosmetic (n = 71), 3.86 mm (95% CI, 3.31-4.41); Titanol (n = 69), 4.51 mm (95% CI, 4.00-5.02); TP Aesthetic (n = 71), 4.13 mm (95% CI, 3.49-4.78); and Tooth Tone (n = 72), 4.21 mm (95% CI, 3.89-4.46). There was a statistically significant difference between archwire groups for color change (P = 0.001) and percentage of coating loss (P = 0.001), with BioCosmetic performing best in both parameters. CONCLUSIONS: There was no difference between the archwires for alignment efficiency. BioCosmetic performed statistically significantly better than did the other groups for both color change and coating loss. REGISTRATION: This trial was registered with the East Midlands NHS Research Ethics Committee (12/EM/0190). PROTOCOL: The protocol was not published before trial commencement. PMID- 29173855 TI - Short-term and long-term effectiveness of powered toothbrushes in promoting periodontal health during orthodontic treatment: A systematic review and meta analysis. AB - INTRODUCTION: Although powered toothbrushes have been reported to reduce gingivitis more than manual toothbrushes in the general population, the evidence regarding orthodontic patients has been inconclusive. Thus, we aimed to compare their effectiveness in relation to any available parameter regarding oral health in orthodontic patients with fixed appliances. METHODS: Searches without restrictions for published and unpublished literature and hand searching took place up to August 2017. Oral-health relevant data from randomized controlled trials of at least 4-weeks duration comparing powered and manual tooth brushing without supervision were reviewed. Data were classified as short term (assessments at 1-3 months) and long term (assessments at >3 months), and the random-effects method was used to combine treatment effects. Individual study risk of bias was assessed using the Cochrane Risk of Bias Tool, and the quality of evidence was evaluated according to the Grades of Recommendation, Assessment, Development and Evaluation approach. RESULTS: The initially identified articles were finally reduced to 9 randomized controlled trials investigating the periodontal health in 434 patients. Eight studies followed patients up to 3 months, and 1 up to 12 months during treatment. One study was at low and the rest at unclear risk of bias. Overall, in the short term, there was low-quality evidence that powered toothbrushes provide a statistically significant benefit compared with manual brushing with regard to the gingival index (weighted mean difference, -0.079; 95% confidence interval, -0.146 to -0.012; P = 0.021) and indexes assessing gingival bleeding (standardized mean difference, -0.637; 95% confidence interval, -1.092 to -0.183; P = 0.006). In the long term, only 1 available study showed a statistically significant benefit of powered over manual toothbrushes with regard to gingival index and bleeding. No differences were observed in probing pocket depth and relative attachment loss. For the rotation oscillation brushes that involved the greatest body of evidence, statistically significant reductions in gingival index and bleeding were demonstrated only in the long-term study. No included study provided quantified measurements regarding caries activity. CONCLUSIONS: Overall, powered toothbrushes may promote gingival health better than manual toothbrushes in orthodontic patients. However, no type demonstrated clear superiority. Better study standardization and reporting in longer follow-up studies are necessary to elucidate the clinical relevance of these results. PMID- 29173856 TI - Changes of bite force and occlusal contacts in the retention phase of orthodontic treatment: A controlled clinical trial. AB - INTRODUCTION: We aimed to determine whether appliance type affects changes in maximum voluntary bite force (MVBF) and the number of occlusal contacts (NOC) during retention, controlling for sex, age, and body mass index. METHODS: The sample comprised 176 examinees (70 male, 106 female) aged 14 to 20 years: 30 had maxillary and mandibular Essix retainers, 30 had wrap-around retainers, and 30 had a combination of fixed mandibular canine-to-canine retainers bonded on each tooth separately (double twisted, 0.254 mm in diameter, stainless steel ligature wire) and Essix retainer in the maxillary arch; 86 with normal occlusion were not treated. MVBF and the NOC were measured immediately after removal of preadjusted edgewise appliances (Roth prescription), 6 weeks after that, and after the next 4 weeks. RESULTS: Increases in MVBF and the NOC were demonstrated, but subjects with 2 Essix retainers showed lower values than did the others. Changes were related to type of appliance, sex, and age (P <0.05) but not to body mass index. The increase in NOC occurred faster than the increase of MVBF, more and sooner with the wrap-around retainer and in male subjects than with the Essix and in female subjects. MVBF and NOC nearly reached the values of the control subjects. CONCLUSIONS: Settling of the occlusion depends on appliance type: it takes longer in female patients and with Essix in both dental arches than with the other tested appliances. PMID- 29173857 TI - Effect of malocclusion on adults seeking orthodontic treatment. AB - INTRODUCTION: Our objective was to examine the Teen Oral Health-related Quality of Life (TOQOL) questionnaire for use in adults receiving orthodontic treatment and assess validity and reliability by age group. METHODS: Teenagers from 10 to 18 years and adults 18 and over completed surveys at the orthodontic clinic at Boston University. The survey consisted of sociodemographic information, dental behavior questions, and the TOQOL instrument. Malocclusion severity was assessed using the Index of Orthodontic Treatment Need. RESULTS: Overall, 161 teens and 146 adults participated. The mean ages were 13 years for the teens and 32 years for the adults. Subjects were represented by both sexes and diverse racial and ethnic backgrounds. In general, scores overall and by domains were higher for adults than for teens, signifying a greater effect of the malocclusion on the quality of life. Mean TOQOL scores as well as emotional and social domain scores (P <0.001) were worse (17.6) in adults than in teens (11.9; P <0.01). Construct validity was supported by strong a association of TOQOL scores with self-reported oral health. The Cronbach alpha was higher in adults overall and for all domains (0.75 in adults compared with 0.68 in teens). CONCLUSIONS: Adults who come for orthodontic treatment appear to be more affected by their malocclusion than are teens. The total TOQOL score and the emotional and social domains were significantly higher for adults. The total TOQOL score and the emotional and social domains were significantly higher (worse) for adults than teens. This project suggested that TOQOL may be a useful way to measure the impact of malocclusion on the quality of life in both adults and teens. PMID- 29173858 TI - Comparison of different midsagittal plane configurations for evaluating craniofacial asymmetry by expert preference. AB - INTRODUCTION: In this study, we aimed to compare 8 candidate midsagittal planes (MSPs) constructed from different median landmarks to determine the most appropriate one for evaluating craniofacial asymmetry. METHODS: We included 30 patients (18 men, 12 women; mean age, 25.7 +/- 6.03 years) who visited the National Health Insurance Service Ilsan Hospital in Gyeonggi-do, Korea, with a complaint of facial asymmetry. Four MSPs passing through 2 median landmarks perpendicular to the Frankfort horizontal plane and 4 other MSPs passing through 3 median landmarks were constructed. Menton, anterior nasal spine, and anterior nasal spine-to-posterior nasal spine line deviations were evaluated using these 8 MSPs. Eight MSPs from 30 subjects were shown to 6 experts, who selected the planes that they considered the most appropriate. RESULTS: Experts most frequently selected the plane passing through nasion and basion perpendicular to the Frankfort horizontal plane (66 of 180 times; P <0.05). In evaluating craniofacial asymmetry, using MSPs passing through 3 median landmarks in the cranial base can lead to underestimation of the asymmetry of the menton, anterior nasal spine, and anterior nasal spine-to-posterior nasal spine line. CONCLUSIONS: We suggest using MSPs perpendicular to the Frankfort horizontal plane or a plane passing through anterior nasal spine in clinical practice. PMID- 29173859 TI - Relapse of anterior crowding 3 and 33 years postretention. AB - INTRODUCTION: The aim of this study was to evaluate the relapse of occlusal characteristics and maxillary and mandibular anterior crowding 3 and 33 years postretention. METHODS: The sample comprised 28 patients, 15 Class I and 13 Class II, treated with 4 premolar extractions, with a mean initial age of 12.72 years (SD, 0.99), a mean final age of 14.74 years (SD, 1.26), and a mean treatment time of 2.02 years (SD, 0.66). The mean short-term postretention age was 20.15 years (SD, 1.34), and the mean long-term postretention age was 49.40 years (SD, 4.54). The mean time of short-term postretention evaluation was 3.70 years (SD, 0.87) and the mean long-term postretention evaluation was 32.95 years (SD, 4.31). The maxillary and mandibular irregularity indexes were assessed on the initial, final, short-term, and long-term postretention stage dental casts. Peer Assessment Rating and the Little indexes were compared among the 4 stages by repeated measures analysis of variance and Tukey tests. RESULTS: Peer Assessment Rating index and maxillary anterior crowding were significantly improved with treatment, had significant relapses in the short term, and a slight and not statistically significant increase from short-term to long-term postretention evaluation. The mandibular irregularity index significantly decreased with treatment, and then significantly and progressively increased in the postretention stages. CONCLUSIONS: The occlusal characteristics and maxillary anterior crowding had significant relapses in the short term and remained stable from the short-term to the long-term postretention stages. Mandibular anterior crowding significantly decreased with treatment, showed a significant relapse in the short term, and continued to significantly increase in the long-term postretention stage. PMID- 29173860 TI - Differences in distances between maxillary posterior root apices and the sinus floor according to skeletal pattern. AB - INTRODUCTION: The aim of this study was to evaluate the distances from the maxillary posterior root apices to the inferior wall of the maxillary sinus using cone-beam computed tomography images and the relationships between roots and maxillary sinus according to age, sex, and skeletal pattern. METHODS: Three dimensional images of each root were checked, and the distances were measured along the true vertical axis from the apex of the root to the sinus floor in 118 patients (63 male, 55 female) aged 10 to 28 years. Compare-means statistic tests were done to assess the differences between groups classified according to age, sex, and skeletal pattern. RESULTS: The frequency of root contact with the sinus floor increased from 70% at the second premolar to more than 80% at the buccal roots of the first and second molars. Male and older age (20-28 years) groups had significantly smaller distances or more protrusion of the root into the sinus than female and younger age (10-20 years) groups. The distances were shorter, or there was more protrusion of the root into the sinus in the hyperdivergent, down canted palatal plane, and large gonial angle groups. CONCLUSIONS: Male, older age, hyperdivergent skeletal pattern, and large gonial angle groups had significantly closer distances between maxillary root tips and the sinus floor or more protrusion of the roots into the sinus. The intrusion of the maxillary molars in those situations may be difficult and slow because of the pneumatized maxillary sinus. PMID- 29173861 TI - Possible alternative treatment for mandibular asymmetry by local unilateral IGF-1 injection into the mandibular condylar cavity: Experimental study in mice. AB - INTRODUCTION: The purpose of this study was to investigate whether a local unilateral IGF-1 injection into the mandibular condylar cavity can induce unilateral endochondral mandibular growth without any systemic adverse effects. METHODS: Seventy-five 3-week-old male Jcl:ICR mice were used in this study. The mice were divided into 2 groups: control group (n = 22) and IGF-1 group (n = 53). In the IGF-1 group, human IGF-1 was injected into the right mandibular condylar cavity, and phosphate-buffered saline solution was injected into the left cavity, 3 times per week for 10 weeks. RESULTS: There was no significant difference in body weight, serum human IGF-1 concentration, and soft tissue thickness of the cheeks including the masseter muscles between the 2 groups. Unilateral IGF-1 injection induced a lateral shift of the mandible to the contralateral side, and microcomputed tomogtraphy analysis showed that unilateral IGF-1 injection induced endochondral growth in the condyle. Col2, Ihh, and Runx2 were extensively upregulated by the local unilateral IGF-1 injection in real-time reverse transcription polymerase chain reaction analysis. Proliferation marker KI67, IGF 1 signaling molecule AKT1, and chondrogenic differentiation marker Col2 were strongly expressed in the IGF-1 injected condyle by immunohistochemistry. Vital labeling showed that the distance between the labels was increased in the IGF-1 injection group compared with that of the control group. CONCLUSIONS: The results verified in this study indicated that local unilateral IGF-1 injection into the mandibular condylar cavity successfully induced unilateral endochondral mandibular growth in mice without any systemic adverse effects. Thus, local unilateral IGF-1 injection into the mandibular condylar cavity could be a useful alternative for mandibular asymmetry therapy during the growth period. However, additional experimental and clinical studies will be necessary to prove the real effect of this new therapy. PMID- 29173862 TI - Effects of vacuum-formed retainers on periodontal status and their retention efficiency. AB - INTRODUCTION: The stability of treatment results is a major concern in orthodontics. Numerous retention regimens to maintain stability have been introduced. The objectives of this study were to evaluate the effects of vacuum formed retainers (VFRs) on periodontal tissues and the retention efficiency of VFRs. METHODS: Forty patients were included in this study. Clinical effectiveness of VFRs for nighttime use only over a 12-month period was assessed by using the American Board of Orthodontics' Objective Grading System. Periodontal measurements and indexes were recorded and evaluated immediately after removal of the braces and after 1, 6, and 12 months of VFR use. RESULTS: There was no significant change in the total Objective Grading System score between the end of the active treatment period and the end of the 12-month retention period. However, regarding periodontal measurements, the plaque and gingival indexes decreased, whereas the bleeding on probing, probing depth, calculus index, and clinical attachment loss increased between the evaluated periods. CONCLUSIONS: In terms of periodontal health, the use of VFRs resulted in a slight periodontal attachment loss that seemed to be clinically insignificant, without gingival inflammation or recession. In terms of stability, VFRs were found to be effective in orthodontic retention. PMID- 29173863 TI - Two-dimensional vs 3-dimensional comparison of alveolar bone over maxillary incisors with A-point as a reference. AB - INTRODUCTION: Our objectives were to compare, relative to A-point, (1) bone thickness over the most forward maxillary incisor (MFMI) in 2 dimensions vs 3 dimensions, and (2) bone thickness and inclination of each maxillary incisor in 3 dimensions. METHODS: Thirty-four cone-beam computed tomography (CBCT) images were coded, and 2-dimensional (2D) cephalograms were derived from each image using Dolphin software (Dolphin Imaging and Management Solutions, Chatsworth, Calif). A point and the MFMI crown were located. After reliability tests, alveolar bone buccal to 3 points on the MFMI root, bone to reference line Frankfort horizontal (FH)-A-point, and incisor inclination were measured. This procedure was repeated on the 3-dimensional (3D) CBCT images comparing MFMI with all maxillary incisors. The 2D and 3D measurements were compared using paired t tests, and 3D measurements were compared with analysis of variance. A 5% significance level was used for all tests. RESULTS: The MFMI's buccal bone thickness at the root apices and the distance between buccal bone and FH-A-point line at 2 root points were significantly greater in 2 dimensions than in 3 dimensions. In 3 dimensions, bone thickness at MFMI's root apex and the distance from FH-A-point line at all root points were significantly greater than those of the lateral incisors. Bone buccal to MFMI was significantly smaller than at the lateral incisors 3 mm from the cementoenamel junction. CONCLUSIONS: Evaluation of 2D CBCT derivations can result in overestimation of alveolar bone buccal to the maxillary incisor root apices compared with 3D evaluations. The anterior nasal spine obscures bone measurements over the maxillary incisors in 2 dimensions. PMID- 29173864 TI - Effect of temporomandibular joint articular disc repositioning on anterior open bite malocclusion: An orthodontic-surgical approach. AB - An anterior open bite is a challenge to orthodontic treatment; it has a multifactorial etiology and a wide range of intervention options. Temporomandibular joint (TMJ) disorders are a risk factor for the development of malocclusions such as the anterior open bite, especially in patients who have TMJ osteoarthritis with disc displacement. Articular disc repositioning surgery is an available option for treating this pathology, and it contributes to maintaining the condyles in a more stable position. The aim of this article was to report the case of a 20-year-old woman diagnosed with anterior open bite and TMJ osteoarthritis with bilateral disc displacement. The patient received both orthodontic treatment and TMJ disc repositioning surgery. Cone-beam computed tomography was used to create 3-dimensional models of the condyles with regional superposition, and assessment of bone remodeling was performed at different time intervals. Complete orthodontic and surgical treatment time was approximately 12 months. The results provided a stable correction of the patient's anterior open bite with a 2-year follow-up and favorable bone remodeling of the condyles due to functional improvement of the TMJ.

AB - A modified C-palatal plate (MCPP) is introduced as a treatment option for adolescent patients with Class I malocclusion and severe overjet. A boy, 10 years 11 months old, was successfully treated without extractions in 22 months. Indications for clinical application of the MCPP as well as procedures and biomechanical analysis of the treatment effects are described in detail. The MCPP was used to distalize the maxillary dentition. The results were stable 1 year after retention. Clinicians should consider the application of MCPP as a nonextraction treatment option for adolescents with Class I malocclusion and severe overjet when the patient or parent refuses extractions. PMID- 29173866 TI - Computer-aided design and manufacture of hyrax devices: Can we really go digital? AB - The aim of this pilot study was to illustrate the feasibility of a new digital procedure to fabricate metallic orthodontic appliances. Hyrax appliances for rapid palatal expansion were produced for 3 patients using a CAD/CAM procedure without physical impressions or printed models. The work flow consisted of intraoral scanning, digital design with incorporation of a scanned prefabricated expansion screw, direct 3-dimensional metal printing via laser melting, welding of an expansion screw, insertion, and finally activation in the patients' mouths. Finite element analyses of the actual hyrax appliances were performed to ensure that the printable material used in combination with the chosen design would withstand the stress generated during activation. The results of these analyses were positive. The clinical results showed that this procedure is an efficient and viable digital way for constructing metallic orthodontic appliances. The flexibility of the digital appliance design, together with the biocompatibility and strength of the chosen material, offers a huge potential for more advanced appliance design.

AB - Motility is often a pathogenicity determinant of bacteria targeting mucosal tissues. Flagella constitute the machinery that propels bacteria into appropriate niches. Besides motility, the structural component, flagellin, which forms the flagella, targets Toll-like receptor 5 (TLR5) to activate innate immunity. The compartmentalization of flagellin-mediated immunity and the contribution of epithelial cells and dendritic cells in detecting flagellin within luminal and basal sides are highlighted here, respectively. While a direct stimulation of the epithelium mainly results in recruitment of immune cells and production of antimicrobial molecules, TLR5 engagement on parenchymal dendritic cells can contribute to the stimulation of innate lymphocytes such as type 3 innate lymphoid cells, as well as T helper cells. This review, therefore, illustrates how the innate and adaptive immunity to flagellin are differentially regulated by the epithelium and the dendritic cells in response to pathogens that either colonize or invade mucosa. PMID- 29173869 TI - Human Gut Microbiome: Function Matters. AB - The human gut microbiome represents a complex ecosystem contributing essential functions to its host. Recent large-scale metagenomic studies have provided insights into its structure and functional potential. However, the functional repertoire which is actually contributed to human physiology remains largely unexplored. Here, by leveraging recent omics datasets, we challenge current assumptions regarding key attributes of the functional gut microbiome, in particular with respect to its variability. We further argue that the closing of existing gaps in functional knowledge should be addressed by a most-wanted gene list, the development and application of molecular and cellular high-throughput measurements, the development and sensible use of experimental models, as well as the direct study of observable molecular effects in the human host. PMID- 29173870 TI - A reappraisal of small- and large-fiber damage in carpal tunnel syndrome: New insights into the value of the EMLA test for improving diagnostic sensitivity. AB - OBJECTIVES: To reappraise the respective involvement of small- and large-fiber damage in carpal tunnel syndrome (CTS) and to determine the diagnostic sensitivity of autonomic tests compared to conventional nerve conduction study (NCS). METHODS: Thirty-two manual workers complaining of at least unilateral CTS were enrolled. They underwent clinical interview and completed the symptom severity scale of the Boston CTS Questionnaire (sssBCTQ) and the Neuropathic Pain Symptom Inventory (NPSI). In addition, transcarpal NCS was performed to investigate large sensory and motor fibers of the median nerve, while small autonomic fibers were assessed by recording sympathetic skin reflexes (SSR) at the palm and by grading skin wrinkling in response to eutectic mixture of local anesthetic (EMLA) cream application at the pulp of the index finger. For each neurophysiological variable, sensitivity and specificity values for the diagnosis of CTS were calculated and clinical correlations were studied. RESULTS: Among 64 hands examined, 36 were clinically symptomatic, while 22 were clinically asymptomatic and served as controls. Among all the neurophysiological variables studied, only the values of transcarpal sensory nerve conduction velocity and the EMLA test grade were found to be more altered in clinically symptomatic hands, with also a trend towards prolonged distal motor latency. Overall, for the diagnosis of clinically symptomatic CTS, NCS, SSR, and the EMLA test had a sensitivity of 66.7%, 22.2%, and 69.4%, respectively, and a specificity of 72.7%, 90.9%, and 50%, respectively. Combining NCS and the EMLA test led to a sensitivity of 88.9% and a specificity of 45.4%. The sssBCTQ (r=-0.34, P=0.009) and the total NPSI score (r=-0.41, P=0.001) correlated to a more altered EMLA test grade, but not to any NCS or SSR variables. In symptomatic hands, burning sensation was associated with more severe small-fiber lesion, while other pain and sensory symptoms were rather found to be reduced in case of large-fiber damage, evidenced by NCS alteration. CONCLUSIONS: This study confirms the discrepancy between conventional NCS results and clinical presentation of CTS, but still suggests a major involvement of Abeta fibers in the positive sensory symptoms of CTS, excepting burning sensation. On the other hand, the EMLA test was found to correlate with clinical data and to be able to improve sensitivity of neurophysiological investigation in diagnosing CTS.

PMID- 29173872 TI - Application of intraoperative transluminal core-biopsy for diagnosis of pancreatic head mass: A single center 15-year experience. AB - BACKGROUND: Pathology is the gold standard for diagnosis of pancreatic cancer. Preoperative endoscopic ultrasound-guided biopsy is an expensive procedure that is not routine in developing countries, hence a cheap, reliable alternative is required. AIM: To evaluate the effectiveness and safety of a new technique of intraoperative biopsy from pancreatic head mass. METHODS: Patients undergoing intraoperative transluminal core-biopsy (TLCB) for pancreatic head mass from January 2000 to June 2015 were included in this study. Following Kocher's maneuver, a biopsy was taken from the mass through the duodenum transluminally, using a commercial 16G automatic core-biopsy needle. Multiple tissue specimens were obtained for intraoperative frozen section examination. Depending on the pathological results, a decision was taken to either perform pancreaticoduodenectomy, duodenum-preserving pancreatic head resection, bypass surgery, or to just terminate the operation. The malignancy status of the lesion was confirmed by postoperative pathological examination and/or long-term follow up of the patients. RESULTS: A total of 525 patients were included. Intraoperative pathological reports revealed 436 malignant cases and 89 cases without evidence of malignancy. The sensitivity, specificity, false positive rate, and false negative rate were 97.7%, 100%, 0%, and 2.3%, respectively. Complications occurred in 2 patients. CONCLUSION: TLCB is a quick, safe, effective, and accurate method for intraoperative diagnosis method in patients with pancreatic head mass; it can provide reliable evidence for surgical decision making. PMID- 29173873 TI - Preoperative factors associated with technical difficulties of laparoscopic cholecystectomy in acute cholecystitis. AB - OBJECTIVE: To identify preoperative factors associated with surgical time and conversion of the laparoscopic cholecystectomy (LC) to open surgery in subjects with acute cholecystitis (AC). METHOD: We developed a cross-sectional study that included 99 subjects older than 17 years with definitive diagnosis of AC who had undergone to LC. Preoperative variables such as clinical data, laboratory markers and ultrasound findings as wall thickness, the size of the major calculus and the presence of: perivesicular fluid, multiple cholelithiasis, biliary mud or microlithiasis were registered. We consider indirect measures of technical difficulties of LC the total surgical time and the need for conversion to open surgery. We used the square chi and Mann-Whitney U test to stablish the correlation between preoperative variables and the technical difficulties of LC. We build ROC curves of the variables with significant statistical association (p <=0.05 and 95% confidence interval [95%CI]) to determine the cut-off points of better sensitivity and specificity to predict conversion of LC to open surgery. RESULTS: A gallbladder wall thickness >=6mm detected by ultrasound has a sensitivity of 87.5% and a specificity of 62.6% with OR 11.71 (95%CI: 1.38-99; p = 0.008) for predict conversion to open surgery. There was no relationship between surgical time and the preoperative evaluated variables. CONCLUSION: The gallbladder wall thickness detected by the ultrasound is associated with the need of conversion of LC to open surgery in subjects with AC, furthermore this finding could warn the surgeon on the complexity with a particular patient.

AB - OBJECTIVE: This study aims to evaluate the effects of Pilates exercises for a decreasing pain in pregnant women. METHODS: A total of 40 pregnant women were divided into two groups, a control group (followed a standard pregnancy exercise regimen) and a Pilates group (completed a Pilates exercise regimen). A pain assessment was carried out after exercise, using a visual analog scale. The Pilates group workout program lasted 70-80 min per day, once a week, for 8 weeks. RESULTS: The reduction in the level of pain was found to be significantly greater in the group of pregnant women who completed the Pilates workout (p < 0.05). CONCLUSIONS: The results of this study indicated that Pilates is an effective, healthy, and feasible method of reducing pain in pregnancy, and is therefore a beneficial alternative workout for the suppression of pain in the third trimester of pregnancy. PMID- 29173893 TI - A novel in-hospital meal service improves protein and energy intake. AB - BACKGROUND & AIMS: Improvement of hospital meal services is a strategy to optimize protein and energy intake and prevent or treat malnutrition during hospitalization. FoodforCare (FfC) is a new concept comprising 6-protein-rich meals per day, provided directly at the bedside following proactive advice from a nutritional assistant. Our aim is to investigate whether this new concept, FfC, improves dietary intake and patient satisfaction, compared to the traditional 3 meals a day service (TMS). METHODS: We performed a quasi experimental study at medical (Gastroenterology) and surgical (Gynecology, Urology, Orthopedics) wards. Patients were offered TMS (July 2015-May 2016; n = 326) or FfC meal service (after stepwise introduction per ward from January 2016-December 2016; n = 311). Primary outcome was the mean percentage of protein and energy intake relative to requirements, between patients receiving TMS and those receiving FfC, on the first and fourth day of full oral intake. Patient satisfaction comprised rating of the experienced quality of the meals and the meal service by means of a validated questionnaire. RESULTS: Patient characteristics were similar between groups, with the exception that the FfC group contained more oncology patients (p = 0.028). FfC improved mean daily protein intake (in g/day) relative to requirements (1.2 g/kg/day) at day 1 (mean % +/-SD: 79 +/- 33 vs. 59 +/- 28; p < 0.05) and day 4 (73 +/- 38 vs. 59 +/- 29; p < 0.05). Mean daily energy intake (in kcal/day) relative to requirements improved at day 1 (88 +/- 34 vs. 70 +/- 30; p < 0.05) and day 4 (84 +/- 40 vs. 73 +/- 31; p = 0.05). On a scale of 1-10, patient satisfaction remained unchanged, in terms of food quality (7.7 +/- 1.5 vs. 7.4 +/- 1.4; p = 0.09) and meal service (7.8 +/- 1.3 vs. 7.7 +/- 1.1; p = 0.29). The FfC group was more satisfied with the appearance and smell of the meals (both p < 0.05). CONCLUSIONS: Implementation of this novel meal service substantially improved protein and energy intake while maintaining, and to some extent, improving patient satisfaction.

AB - Current donor cell-dependent strategies can only produce limited "made-to-order" therapeutic natural killer (NK) cells for limited patients. To provide unlimited "off-the-shelf" NK cells that serve many recipients, we designed and demonstrated a holistic manufacturing scheme to mass-produce NK cells from induced pluripotent stem cells (iPSCs). Starting with a highly accessible human cell source, peripheral blood cells (PBCs), we derived a good manufacturing practice compatible iPSC source, PBC-derived iPSCs (PBC-iPSCs) for this purpose. Through our original protocol that excludes CD34+ cell enrichment and spin embryoid body formation, high-purity functional and expandable NK cells were generated from PBC iPSCs. Above all, most of these NK cells expressed no killer cell immunoglobulin like receptors (KIRs), which renders them unrestricted by recipients' human leukocyte antigen genotypes. Hence, we have established a practical "from blood cell to stem cells and back with less (less KIRs)" strategy to generate abundant "universal" NK cells from PBC-iPSCs for a wide range of patients. PMID- 29173895 TI - Mode of Surgical Injury Influences the Source of Urothelial Progenitors during Bladder Defect Repair. AB - The bladder urothelium functions as a urine-blood barrier and consists of basal, intermediate, and superficial cell populations. Reconstructive procedures such as augmentation cystoplasty and focal mucosal resection involve localized surgical damage to the bladder wall whereby focal segments of the urothelium and underlying submucosa are respectively removed or replaced and regeneration ensues. We demonstrate using lineage-tracing systems that urothelial regeneration following augmentation cystoplasty with acellular grafts exclusively depends on host keratin 5-expressing basal cells to repopulate all lineages of the de novo urothelium at implant sites. Conversely, repair of focal mucosal defects not only employs this mechanism, but in parallel host intermediate cell daughters expressing uroplakin 2 give rise to themselves and are also contributors to superficial cells in neotissues. These results highlight the diversity of urothelial regenerative responses to surgical injury and may lead to advancements in bladder tissue engineering approaches. PMID- 29173896 TI - The aPKC-CBP Pathway Regulates Post-stroke Neurovascular Remodeling and Functional Recovery. AB - Epigenetic modifications have emerged as attractive molecular substrates that integrate extrinsic changes into the determination of cell identity. Since stroke related brain damage releases micro-environmental cues, we examined the role of a signaling-induced epigenetic pathway, an atypical protein kinase C (aPKC) mediated phosphorylation of CREB-binding protein (CBP), in post-stroke neurovascular remodeling. Using a knockin mouse strain (CbpS436A) where the aPKC CBP pathway was defective, we show that disruption of the aPKC-CBP pathway in a murine focal ischemic stroke model increases the reprogramming efficiency of ischemia-activated pericytes (i-pericytes) to neural precursors. As a consequence of enhanced cellular reprogramming, CbpS436A mice show an increased transient population of locally derived neural precursors after stroke, while displaying a reduced number of i-pericytes, impaired vascular remodeling, and perturbed motor recovery during the chronic phase of stroke. Together, this study elucidates the role of the aPKC-CBP pathway in modulating neurovascular remodeling and functional recovery following focal ischemic stroke. PMID- 29173897 TI - A COUP-TFII Human Embryonic Stem Cell Reporter Line to Identify and Select Atrial Cardiomyocytes. AB - Reporter cell lines have already proven valuable in identifying, tracking, and purifying cardiac subtypes and progenitors during differentiation of human pluripotent stem cells (hPSCs). We previously showed that chick ovalbumin upstream promoter transcription factor II (COUP-TFII) is highly enriched in human atrial cardiomyocytes (CMs), but not ventricular. Here, we targeted mCherry to the COUP-TFII genomic locus in hPSCs expressing GFP from the NKX2.5 locus. This dual atrial NKX2.5EGFP/+-COUP-TFIImCherry/+ reporter line allowed identification and selection of GFP+ (G+)/mCherry+ (M+) CMs following cardiac differentiation. These cells exhibited transcriptional and functional properties of atrial CMs, whereas G+/M- CMs displayed ventricular characteristics. Via CRISPR/Cas9-mediated knockout, we demonstrated that COUP-TFII is not required for atrial specification in hPSCs. This new tool allowed selection of human atrial and ventricular CMs from mixed populations, of relevance for studying cardiac specification, developing human atrial disease models, and examining distinct effects of drugs on the atrium versus ventricle. PMID- 29173898 TI - Human Pluripotent Stem Cell Differentiation into Functional Epicardial Progenitor Cells. AB - Human pluripotent stem cells (hPSCs) are widely used to study cardiovascular cell differentiation and function. Here, we induced differentiation of hPSCs (both embryonic and induced) to proepicardial/epicardial progenitor cells that cover the heart during development. Addition of retinoic acid (RA) and bone morphogenetic protein 4 (BMP4) promoted expression of the mesodermal marker PDGFRalpha, upregulated characteristic (pro)epicardial progenitor cell genes, and downregulated transcription of myocardial genes. We confirmed the (pro)epicardial like properties of these cells using in vitro co-culture assays and in ovo grafting of hPSC-epicardial cells into chick embryos. Our data show that RA + BMP4-treated hPSCs differentiate into (pro)epicardial-like cells displaying functional properties (adhesion and spreading over the myocardium) of their in vivo counterpart. The results extend evidence that hPSCs are an excellent model to study (pro)epicardial differentiation into cardiovascular cells in human development and evaluate their potential for cardiac regeneration. PMID- 29173900 TI - Movers and Stayers: Novel Assemblages in Changing Environments. AB - Increased attention to species movement in response to environmental change highlights the need to consider changes in species distributions and altered biological assemblages. Such changes are well known from paleoecological studies, but have accelerated with ongoing pervasive human influence. In addition to species that move, some species will stay put, leading to an array of novel interactions. Species show a variety of responses that can allow movement or persistence. Conservation and restoration actions have traditionally focused on maintaining or returning species in particular places, but increasingly also include interventions that facilitate movement. Approaches are required that incorporate the fluidity of biotic assemblages into the goals set and interventions deployed. PMID- 29173899 TI - Distinct Gene Expression and Epigenetic Signatures in Hepatocyte-like Cells Produced by Different Strategies from the Same Donor. AB - Hepatocyte-like cells (HLCs) can be generated through directed differentiation or transdifferentiation. Employing two strategies, we generated induced pluripotent stem cell (iPSC)-HLCs and hiHeps from the same donor cell line. Both types of HLCs clustered distinctly from each other during gene expression profiling. In particular, differences existed in gene expression for phase II drug metabolism and lipid accumulation, underpinned by H3K27 acetylation status in iPSC-HLCs and hiHeps. While distinct phenotypes were achieved in vitro, both types of HLCs demonstrated similar phenotypes following transplantation into Fah-deficient mice. In conclusion, functional HLCs can be obtained from the same donor using two strategies. Global gene expression defined the differences between those populations in vitro. Importantly, both HLCs displayed partial but markedly improved hepatic function following transplantation in vivo, demonstrating plasticity and the potential for cell-based modeling in the dish and cell-based therapy in the future. PMID- 29173901 TI - Clinical impact of dosimetric changes for volumetric modulated arc therapy in log file-based patient dose calculations. AB - PURPOSE: A log file-based method cannot detect dosimetric changes due to linac component miscalibration because log files are insensitive to miscalibration. Herein, clinical impacts of dosimetric changes on a log file-based method were determined. METHODS AND MATERIALS: Five head-and-neck and five prostate plans were applied. Miscalibration-simulated log files were generated by inducing a linac component miscalibration into the log file. Miscalibration magnitudes for leaf, gantry, and collimator at the general tolerance level were +/-0.5mm, +/-1 degrees , and +/-1 degrees , respectively, and at a tighter tolerance level achievable on current linac were +/-0.3mm, +/-0.5 degrees , and +/-0.5 degrees , respectively. Re-calculations were performed on patient anatomy using log file data. RESULTS: Changes in tumor control probability/normal tissue complication probability from treatment planning system dose to re-calculated dose at the general tolerance level was 1.8% on planning target volume (PTV) and 2.4% on organs at risk (OARs) in both plans. These changes at the tighter tolerance level were improved to 1.0% on PTV and to 1.5% on OARs, with a statistically significant difference. CONCLUSIONS: We determined the clinical impacts of dosimetric changes on a log file-based method using a general tolerance level and a tighter tolerance level for linac miscalibration and found that a tighter tolerance level significantly improved the accuracy of the log file-based method. PMID- 29173902 TI - Impact of deformable image registration accuracy on thoracic images with different regularization weight parameter settings. AB - PURPOSE: We assessed the deformable image registration (DIR) accuracy of thoracic images under different regularization weights using commercially available DIR software. METHODS: The thoracic 4-dimensional (4D) CT images of 10 patients were used. The datasets for these patients were provided by DIR-lab (www.dir-lab.com) and included a coordinate list of 300 anatomic landmarks that had been manually identified. The ANAtomically CONstrained Deformation Algorithm (ANACONDA) of RayStation (RaySearch Laboratories, Stockholm, Sweden) was used to deform the peak-inhale to peak-exhale images under different regularization weights (4, 40, 400-default setting, 1500, 4000, 10,000, 15,000, 20,000, 30,000, and 40,000). The regularization weights were changed using a script. The registration error (RE) was determined by calculating the difference at each landmark point between the displacement calculated by the DIR software and that calculated by the landmark. We measured the computation time for each regularization weight setting. RESULTS: High regularization weights resulted in a smaller RE than that observed with lower regularization weights. The RE decreases rapidly with increase in regularization weight before reaching a plateau. No significant difference was found between a regularization weight of 400 and regularization weights of 4, 40, 4000 or 40,000 (P value >0.05). The range of the average time was 8.4-12.2s. CONCLUSIONS: We concluded that the default setting for ANACONDA is stable with respect to regularization weight in the thoracic region. PMID- 29173903 TI - Radioluminescence from Tc-99m in glass predicts local dose. AB - The widely-used gamma-emitter Tc-99m has been shown to lead to optical emissions in mice and glass. We investigated the possibility that these emissions are due to the Cerenkov effect and whether the light emitted is proportional to local dose. By using a Geant4 Monte Carlo model matched to an experimental measurement, we show that the light detected by a small animal optical imaging system provides a 2D map of the dose throughout a glass sample. We conclude that radioluminescence from Tc-99m can be used to quantitatively measure dose in transparent materials, which could have applications in dosimetry and quality assurance. PMID- 29173904 TI - A novel method for assessment of fragmentation and beam-material interactions in helium ion radiotherapy with a miniaturized setup. AB - Radiotherapy with protons and carbon ions enables to deliver dose distributions of high conformation to the target. Treatment with helium ions has been suggested due to their physical and biological advantages. A reliable benchmarking of the employed physics models with experimental data is required for treatment planning. However, experimental data for helium interactions is limited, in part due to the complexity and large size of conventional experimental setups. We present a novel method for the investigation of helium interactions with matter using miniaturized instrumentation based on highly integrated pixel detectors. The versatile setup consisted of a monitoring detector in front of the PMMA phantom of varying thickness and a detector stack for investigation of outgoing particles. The ion type downstream from the phantom was determined by high resolution pattern recognition analysis of the single particle signals in the pixelated detectors. The fractions of helium and hydrogen ions behind the used targets were determined. As expected for the stable helium nucleus, only a minor decrease of the primary ion fluence along the target depth was found. E.g. the detected fraction of hydrogen ions on axis of a 220MeV/u 4He beam was below 6% behind 24.5cm of PMMA. Monte-Carlo simulations using Geant4 reproduce the experimental data on helium attenuation and yield of helium fragments qualitatively, but significant deviations were found for some combinations of target thickness and beam energy. The presented method is promising to contribute to the reduction of the uncertainty of treatment planning for helium ion radiotherapy. PMID- 29173905 TI - Optimization of imaging protocols for myocardial blood flow (MBF) quantification with 18F-flurpiridaz PET. AB - The new PET tracer, 18F-flurpiridaz, with high myocardial extraction allows quantitative myocardial blood flow (MBF) estimation from dynamic PET data and tracer kinetic modeling. The goal of this study is to determine the optimal imaging protocols and parameters using a realistic simulation study. The time activity curves (TACs) of different tissue organs from a 30-s infusion time (IT) of 18F-flurpiridaz in a dynamic PET study were extracted from a previous study. The TACs at different time points were incorporated in a series of realistic 3D XCAT phantoms from which the parameters of a 2-compartment model and the 'true' MBF of 18F-flurpiridaz were determined. The compartmental model was used to generate TACs from 7 additional ITs. PET projection data from the XCAT phantoms were generated using Monte Carlo simulation. They were reconstructed using an OS EM reconstruction algorithm with different update number (N) to obtain dynamic PET images. The blood and myocardial TACs were derived from the dynamic images from which the MBF and %MBF error was estimated. The %MBF error decreases with increasing N of the OS-EM and levels off after ~42. The 30-s IT gave the smallest %MBF error that decreases from ~0.57% to ~19.40%. The MBF for 2-min, 4-min, 8-min and 16-min IT were statistically significant different from the MBF for 30-s IT (P<0.05). Too fast or too slow infusion time gave higher %MBF error. The optimal imaging protocol in dynamic 18F-flurpiridaz PET for accurate quantitative MBF estimation was 30-s IT and N of ~42 for the OS-EM. PMID- 29173906 TI - Optimization of the exposure parameters in digital mammography using contrast detail metrics. AB - PURPOSE: Optimization studies in digital mammography aid to assure the image quality and radiological protection of the patient. The aim of this work is to test effectiveness and applicability of a method based on a Figure of Merit (FOM=(IQFinv)2/AGD) to improve all the exposure parameters (Target/Filter combination, kVp and mAs) in order to improve the image acquisition technique that will provide the best compromise between image quality and the average glandular dose (AGD). METHODS: A contrast-detail analysis, employing the test object CDMAM, was carried out for the digital mammography unit manufactured by Lorad Hologic - model Selenia. We simulated two breast thicknesses using phantoms and a Figure of Merit as optimization tool, which includes an indicator of image quality, the IQFinv and the average glandular dose. Images of the ACR and TORMAM phantoms were obtained with both, automatic and optimized exposure parameters. In order to compare the image quality, the SNR (Signal to Noise Ratio) was measured in each image. RESULTS: In the two phantoms, for both 4.5 and 7.5cm thicknesses, the AGDs obtained with the optimized parameters show a reduction. In addition, the images obtained with the optimized exposure parameters, had the same or a better image quality when compared to the images obtained using the automatic mode. CONCLUSIONS: The proposed optimization methodology proved to be an effective tool to improve the digital mammography unit, due to the use of objective metrics for evaluation and validation of the results. PMID- 29173907 TI - A software platform for statistical evaluation of patient respiratory patterns in radiation therapy. AB - AIM: The aim of this work was to design and evaluate a software tool for analysis of a patient's respiration, with the goal of optimizing the effectiveness of motion management techniques during radiotherapy imaging and treatment. MATERIALS AND METHODS: A software tool which analyses patient respiratory data files (.vxp files) created by the Varian Real-Time Position Management System (RPM) was developed to analyse patient respiratory data. The software, called RespAnalysis, was created in MATLAB and provides four modules, one each for determining respiration characteristics, providing breathing coaching (biofeedback training), comparing pre and post-training characteristics and performing a fraction-by fraction assessment. The modules analyse respiratory traces to determine signal characteristics and specifically use a Sample Entropy algorithm as the key means to quantify breathing irregularity. Simulated respiratory signals, as well as 91 patient RPM traces were analysed with RespAnalysis to test the viability of using the Sample Entropy for predicting breathing regularity. RESULTS: Retrospective assessment of patient data demonstrated that the Sample Entropy metric was a predictor of periodic irregularity in respiration data, however, it was found to be insensitive to amplitude variation. Additional waveform statistics assessing the distribution of signal amplitudes over time coupled with Sample Entropy method were found to be useful in assessing breathing regularity. CONCLUSIONS: The RespAnalysis software tool presented in this work uses the Sample Entropy method to analyse patient respiratory data recorded for motion management purposes in radiation therapy. This is applicable during treatment simulation and during subsequent treatment fractions, providing a way to quantify breathing irregularity, as well as assess the need for breathing coaching. It was demonstrated that the Sample Entropy metric was correlated to the irregularity of the patient's respiratory motion in terms of periodicity, whilst other metrics, such as percentage deviation of inhale/exhale peak positions provided insight into respiratory amplitude regularity. PMID- 29173908 TI - Impact of pixel-based machine-learning techniques on automated frameworks for delineation of gross tumor volume regions for stereotactic body radiation therapy. AB - The aim of this study was to investigate the impact of pixel-based machine learning (ML) techniques, i.e., fuzzy-c-means clustering method (FCM), and the artificial neural network (ANN) and support vector machine (SVM), on an automated framework for delineation of gross tumor volume (GTV) regions of lung cancer for stereotactic body radiation therapy. The morphological and metabolic features for GTV regions, which were determined based on the knowledge of radiation oncologists, were fed on a pixel-by-pixel basis into the respective FCM, ANN, and SVM ML techniques. Then, the ML techniques were incorporated into the automated delineation framework of GTVs followed by an optimum contour selection (OCS) method, which we proposed in a previous study. The three-ML-based frameworks were evaluated for 16 lung cancer cases (six solid, four ground glass opacity (GGO), six part-solid GGO) with the datasets of planning computed tomography (CT) and 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT images using the three-dimensional Dice similarity coefficient (DSC). DSC denotes the degree of region similarity between the GTVs contoured by radiation oncologists and those estimated using the automated framework. The FCM-based framework achieved the highest DSCs of 0.79+/-0.06, whereas DSCs of the ANN-based and SVM-based frameworks were 0.76+/-0.14 and 0.73+/-0.14, respectively. The FCM-based framework provided the highest segmentation accuracy and precision without a learning process (lowest calculation cost). Therefore, the FCM-based framework can be useful for delineation of tumor regions in practical treatment planning. PMID- 29173909 TI - Voxel-by-voxel correlation between radiologically radiation induced lung injury and dose after image-guided, intensity modulated radiotherapy for lung tumors. AB - PURPOSE: To correlate radiation dose to the risk of severe radiologically-evident radiation-induced lung injury (RRLI) using voxel-by-voxel analysis of the follow up computed tomography (CT) of patients treated for lung cancer with hypofractionated helical Tomotherapy. METHODS AND MATERIALS: The follow-up CT scans from 32 lung cancer patients treated with various regimens (5, 8, and 25 fractions) were registered to pre-treatment CT using deformable image registration (DIR). The change in density was calculated for each voxel within the combined lungs minus the planning target volume (PTV). Parameters of a Probit formula were derived by fitting the occurrences of changes of density in voxels greater than 0.361gcm-3 to the radiation dose. The model's predictive capability was assessed using the area under receiver operating characteristic curve (AUC), the Kolmogorov-Smirnov test for goodness-of-fit, and the permutation test (Ptest). RESULTS: The best-fit parameters for prediction of RRLI 6months post RT were D50 of 73.0 (95% CI 59.2.4-85.3.7)Gy, and m of 0.41 (0.39-0.46) for hypofractionated (5 and 8 fractions) and D50 of 96.8 (76.9-123.9)Gy, and m of 0.36 (0.34-0.39) for 25 fractions RT. According to the goodness-of-fit test the null hypothesis of modeled and observed occurrence of RRLI coming from the same distribution could not be rejected. The AUC was 0.581 (0.575-0.583) for fractionated and 0.579 (0.577-0.581) for hypofractionated patients. The predictive models had AUC>upper 95% band of the Ptest. CONCLUSIONS: The correlation of voxel-by-voxel density increase with dose can be used as a support tool for differential diagnosis of tumor from benign changes in the follow-up of lung IMRT patients. PMID- 29173910 TI - EPID-based in vivo dosimetry for stereotactic body radiotherapy of non-small cell lung tumors: Initial clinical experience. AB - PURPOSE: EPID-based in vivo dosimetry (IVD) has been implemented for stereotactic body radiotherapy treatments of non-small cell lung cancer to check both isocenter dose and the treatment reproducibility comparing EPID portal images. METHODS: 15 patients with lung tumors of small dimensions and treated with volumetric modulated arc therapy were enrolled for this initial experience. IVD tests supplied ratios R between in vivo reconstructed and planned isocenter doses. Moreover a gamma-like analysis between daily EPID portal images and a reference one, in terms of percentage of points with gamma-value smaller than 1, Pgamma<1, and mean gamma-values, gammamean, using a local 3%-3mm criteria, was adopted to check the treatment reproducibility. Tolerance levels of 5% for R ratio, Pgamma<1 higher than 90% and gammamean lower than 0.67 were adopted. RESULTS: A total of 160 EPID images, two images for each therapy session, were acquired during the treatment of the 15 patients. The overall mean of the R ratios was equal to 1.005+/-0.014 (1 SD), with 96.9% of tests within+/-5%. The 2D image gamma-like analysis showed an overall gammamean of 0.39+/-0.12 with 96.1% of tests within the tolerance level, and an average Pgamma<1 value equal to 96.4+/-3.6% with 95.4% of tests with Pgamma<1>90%. Paradigmatic discrepancies were observed in three patients: a set-up error and a patient morphological change were identified thanks to CBCT image analysis whereas the third discrepancy was not fully justified. CONCLUSIONS: This procedure can provide improved patient safety as well as a first step to integrate IVD and CBCT dose recalculation. PMID- 29173911 TI - Medical image segmentation based on level set and isoperimetric constraint. AB - Level set based methods are being increasingly used in image segmentation. In these methods, various shape constraints can be incorporated into the energy functionals to obtain the desired shapes of the contours represented by their zero level sets of functions. Motivated by the isoperimetric inequality in differential geometry, we propose a segmentation method in which the isoperimetric constrain is integrated into a level set framework to penalize the ratio of its squared perimeter to its enclosed area of an active contour. The new model can ensure the compactness of segmenting objects and complete missing or/and blurred parts of their boundaries simultaneously. The isoperimetric shape constraint is free of explicit expressions of shapes and scale-invariant. As a result, the proposed method can handle various objects with different scales and does not need to estimate parameters of shapes. Our method can segment lesions with blurred or/and partially missing boundaries in ultrasound, Computed Tomography (CT) and Magnetic Resonance (MR) images efficiently. Quantitative evaluation also confirms that the proposed method can provide more accurate segmentation than two well-known level set methods. Therefore, our proposed method shows potential of accurate segmentation of lesions for applying in diagnoses and surgical planning.

AB - PURPOSE: To create a synthetic CT (sCT) from conventional brain MRI using a patch based method for MRI-only radiotherapy planning and verification. METHODS: Conventional T1 and T2-weighted MRI and CT datasets from 13 patients who underwent brain radiotherapy were included in a retrospective study whereas 6 patients were tested prospectively. A new contribution to the Non-local Means Patch-Based Method (NMPBM) framework was done with the use of novel multi-scale and dual-contrast patches. Furthermore, the training dataset was improved by pre selecting the closest database patients to the target patient for computation time/accuracy balance. sCT and derived DRRs were assessed visually and quantitatively. VMAT planning was performed on CT and sCT for hypothetical PTVs in homogeneous and heterogeneous regions. Dosimetric analysis was done by comparing Dose Volume Histogram (DVH) parameters of PTVs and organs at risk (OARs). Positional accuracy of MRI-only image-guided radiation therapy based on CBCT or kV images was evaluated. RESULTS: The retrospective (respectively prospective) evaluation of the proposed Multi-scale and Dual-contrast Patch-Based Method (MDPBM) gave a mean absolute error MAE=99.69+/-11.07HU (98.95+/-8.35HU), and a Dice in bones DIbone=83+/-0.03 (0.82+/-0.03). Good agreement with conventional planning techniques was obtained; the highest percentage of DVH metric deviations was 0.43% (0.53%) for PTVs and 0.59% (0.75%) for OARs. The accuracy of sCT/CBCT or DRRsCT/kV images registration parameters was <2mm and <2 degrees . Improvements with MDPBM, compared to NMPBM, were significant. CONCLUSION: We presented a novel method for sCT generation from T1 and T2 weighted MRI potentially suitable for MRI-only external beam radiotherapy in brain sites. PMID- 29173913 TI - Temporally separating Cherenkov radiation in a scintillator probe exposed to a pulsed X-ray beam. AB - Cherenkov radiation is generated in optical systems exposed to ionising radiation. In water or plastic devices, if the incident radiation has components with high enough energy (for example, electrons or positrons with energy greater than 175keV), Cherenkov radiation will be generated. A scintillator dosimeter that collects optical light, guided by optical fibre, will have Cherenkov radiation generated throughout the length of fibre exposed to the radiation field and compromise the signal. We present a novel algorithm to separate Cherenkov radiation signal that requires only a single probe, provided the radiation source is pulsed, such as a linear accelerator in external beam radiation therapy. We use a slow scintillator (BC-444) that, in a constant beam of radiation, reaches peak light output after 1 microsecond, while the Cherenkov signal is detected nearly instantly. This allows our algorithm to separate the scintillator signal from the Cherenkov signal. The relative beam profile and depth dose of a linear accelerator 6MV X-ray field were reconstructed using the algorithm. The optimisation method improved the fit to the ionisation chamber data and improved the reliability of the measurements. The algorithm was able to remove 74% of the Cherenkov light, at the expense of only 1.5% scintillation light. Further characterisation of the Cherenkov radiation signal has the potential to improve the results and allow this method to be used as a simpler optical fibre dosimeter for quality assurance in external beam therapy. PMID- 29173914 TI - Conversion factors of effective and equivalent organ doses with the air kerma area product in patients undergoing coronary angiography and percutaneous coronary interventions. AB - To derive effective dose (E), organ dose (HT) and conversion factors with the air kerma area product (KAP) in coronary angiography (CA) and percutaneous coronary intervention (PCI) by the radial route, using the ICRP 103 tissue weighting factors. The study included 34 patients referred for CA and 31 for PCI. E and HT were derived from in-the-field KAP measurements using Montecarlo methods. Median KAP of 23.2 and 56.8Gycm2 and E of 6.9 and 20.0mSv were found for CA and PCI, respectively. Mean KAP and E were significantly higher in males than in females (52.4+/-40.0 vs 32.3+/-16.6Gycm2; p=0.02) and (16.8+/-13.6 vs 10.7+/-5.8mSv; p=0.04). KAP (r=0.39; p=0.001) and E (r=0.34; p=0.005) showed a significant correlation with the patient's weight. Conversion factors between KAP and E (E/KAP) were 0.30+/-0.04mSvGy-1cm-2 for CA and 0.33+/-0.05mSvGy-1cm-2 for PCI. No significant differences in the E/KAP between males and females were found (0.31+/ 0.05 vs 0.33+/-0.05; p=0.08). Again, no significant correlation was found between E/KAP and patient's weight (r=0.23; p=0.07). The correlation between E and KAP was excellent for CA (r=0.99) and PCI (r=0.96). The correlation between HT and KAP ranged from r=0.87 to r=1 and from r=0.71 to r=0.98 for CA and PCI, respectively. A single factor, the total KAP, could be used for a specific acquisition protocol to reliably estimate E and HT without the need of a patient's specific analysis. Conversion factors might be installation, X-ray beam quality or protocol dependent. PMID- 29173915 TI - Optimization of a large-area detector-block based on SiPM and pixelated LYSO crystal arrays. AB - We present the performance evaluation of a large-area detector module based on the ArrayC-60035-64P, an 8*8 array of tileable, 7.2mm pitch, silicon photomultipliers (SiPM) by SensL, covering a total area of 57.4mm*57.4mm. We characterized the ArrayC-60035-64P, operating at room temperature, using LYSO pixelated crystal arrays of different pitch sizes (1.075, 1.430, 1.683, 2.080 and 2.280mm) to determine the resolvable crystal size. After an optimization process, a 7mm thick coupling light guide was used for all crystal pitches. To identify the interaction position a 16-channel (8 columns, 8 rows) symmetric charge division (SCD) readout board together with a center-of-gravity algorithm was used. Based on this, we assembled the detector modules using a 40*40 LYSO, 1.43mm pitch array, covering the total detector area. Calibration was performed using a 137Cs source resulting in excellent crystal maps with minor geometric distortion, a mean 4.1 peak-to-valley ratio and 9.6% mean energy resolution for 662keV photons in the central region. The resolvability index was calculated in the x and y directions with values under 0.42 in all cases. We show that these large area SiPM arrays, combined with a 16-channel SCD readout board, can offer high spatial resolution, without processing a big number of signals, attaining excellent energy resolution and detector uniformity. PMID- 29173916 TI - Dosimetric effect of uncorrected rotations in lung SBRT with stereotactic imaging guidance. AB - PURPOSE: To evaluate the dosimetric impact of uncorrected rotations on the planning target volume (PTV) coverage for early stage non-small cell lung cancer patients treated with stereotactic body radiotherapy using Brainlab ExacTrac image guidance. METHODS: Twenty-two patients were retrospectively selected. Two scenarios of uncorrected rotations were simulated with magnitude of 1 degrees , 2 degrees , 3 degrees and 5 degrees : (1) rotation around the treatment isocenter; and (2) roll and yaw rotations around a setup isocenter. The D95 of PTV from recalculated dose on the rotated CT was compared to that from the clinical plan. A logistic regression model was used to predict the probability of dose differences between recalculated and original plans that are less than 2% based on the rotation angle, PTV volume, and distance between the treatment and setup isocenter. RESULTS: Logistic regression model showed the uncorrected isocentric rotations of up to 2.5 degrees in all directions have negligible dosimetric impact. For non-isocentric rotations, a rotational error of 2 degrees may cause significant under-dose of the PTV. Statistically significant (p<0.05) parameters in the logistic regression model were angle for isocentric rotations, angle and distance for non-isocentric roll rotations, and angle, distance and the PTV volume for non-isocentric yaw rotations. CONCLUSIONS: The severity of the dose deviations due to uncorrected rotations depends on the type and magnitude of the rotation, the volume of the PTV, and the distance between the treatment and setup isocenter, which should be taken into consideration when making clinical judgment of whether the rotational error could be ignored. PMID- 29173917 TI - Comparison between new-generation SiPM-based and conventional PMT-based TOF PET/CT. AB - PURPOSE: This study aimed to determine whether the SiPM-PET/CT, Discovery MI (DMI) performs better than the PMT-PET/CT system, Discovery 710 (D710). METHODS: The physical performance of both systems was evaluated using NEMA NU 2 standards. Contrast (%), uniformity and image noise (%) are criteria proposed by the Japanese Society of Nuclear Medicine (JSNM) for phantom tests and were determined in images acquired from Hoffman and uniform phantoms using the DMI and D710. Brain and whole-body [18F]FDG images were also acquired from a healthy male using the DMI and D710. RESULTS: The spatial resolution at 1.0cm off-center in the DMI and D710 was 3.91 and 4.52mm, respectively. The sensitivity of the DMI and D710 was 12.62 and 7.50cps/kBq, respectively. The observed peak noise-equivalent count rates were 185.6kcps at 22.5kBq/mL and 137.0kcps at 29.0kBq/mL, and the scatter fractions were 42.1% and 37.9% in the DMI and D710, respectively. The D710 had better contrast recovery and lower background variability. Contrast, uniformity and image noise in the DMI were 61.0%, 0.0225, and 7.85%, respectively. These outcomes were better than those derived from the D710 and satisfied the JSNM criteria. Brain images acquired by the DMI had better grey-to-white matter contrast and lower image noise at the edge of axial field of view. CONCLUSIONS: The DMI offers better sensitivity, performance under conditions of high count rates and image quality than the conventional PMT-PET/CT system, D710. PMID- 29173918 TI - Evaluation of digital tomosynthesis reconstruction algorithms used to reduce metal artifacts for arthroplasty: A phantom study. AB - To investigate methods to reduce metal artifacts during digital tomosynthesis for arthroplasty, we evaluated five algorithms with and without metal artifact reduction (MAR)-processing tested under different radiation doses (0.54, 0.47, and 0.33mSv): adaptive steepest descent projection onto convex sets (ASD-POCS), simultaneous algebraic reconstruction technique total variation (SART-TV), filtered back projection (FBP), maximum likelihood expectation maximization (MLEM), and SART. The algorithms were assessed by determining the artifact index (AI) and artifact spread function (ASF) on a prosthesis phantom. The AI data were statistically analyzed by two-way analysis of variance. Without MAR-processing, the greatest degree of effectiveness of the MLEM algorithm for reducing prosthetic phantom-related metal artifacts was achieved by quantification using the AI (MLEM vs. ASD-POCS, SART-TV, SART, and FBP; all P<0.05). With MAR processing, the greatest degree of effectiveness of the MLEM, ASD-POCS, SART-TV, and SART algorithms for reducing prosthetic phantom-related metal artifacts was achieved by quantification using the AI (MLEM, ASD-POCS, SART-TV, and SART vs. FBP; all P<0.05). When assessed by ASF, metal artifact reduction was largest for the MLEM algorithm without MAR-processing and ASD-POCS, SART-TV, and SART algorithm with MAR-processing. In ASF, the effect of metal artifact reduction was always greater at reduced radiation doses, regardless of which reconstruction algorithm with and without MAR-processing was used. In this phantom study, the MLEM algorithm without MAR-processing and ASD-POCS, SART-TV, and SART algorithm with MAR-processing gave improved metal artifact reduction. PMID- 29173919 TI - Dosimetric evaluation near lung and soft tissue interface region during respiratory-gated and non-gated radiotherapy: A moving phantom study. AB - Challenges in treating lung tumours are related to the respiratory-induced tumour motion and the accuracy of dose calculation in charged particle disequilibrium condition. The dosimetric characteristics near the interface of lung and Perspex media in a moving phantom during respiratory-gated and non-gated radiotherapy were investigated using Gafchromic EBT2 and the MOSkin detector. The MOSkin detectors showed good agreement with the EBT2 films during static and gated radiotherapy. In static radiotherapy, the penumbral widths were found to be 3.66mm and 7.22mm in Perspex and lung media, respectively. In non-gated (moving) radiotherapy with 40mm respiratory amplitude, dose smearing effect was observed and the penumbral widths were increased to 28.81mm and 26.40mm, respectively. This has been reduced to 6.85mm and 9.81mm, respectively, in gated radiotherapy with 25% gating window. There were still some dose discrepancies as compared to static radiotherapy due to the residual motion. This should be taken into account in the margin generation for the target tumour. PMID- 29173920 TI - Evaluation and clinical implementation of in vivo dosimetry for kV radiotherapy using radiochromic film and micro-silica bead thermoluminescent detectors. AB - PURPOSE: kV radiotherapy treatment calculations are based on flat, homogenous, full-scatter reference conditions. However, clinical treatments often include surface irregularities and inhomogeneities, causing uncertainty. Therefore, confirmation of actual delivered doses in vivo is valuable. The current study evaluates, and implements, radiochromic film and micro silica bead TLD for in vivo kV dosimetry. METHODS: The kV energy and dose response of EBT3 film and silica bead TLD was established and uncertainty budgets determined. In vivo dosimetry measurements were made for a consecutive series of 30 patients using the two dosimetry systems. RESULTS: Energy dependent calibration factors were required for both dosimetry systems. The standard uncertainty estimate for in vivo measurement with film was 1.7% and for beads was 1.5%. The mean measured dose was -2.1% for film and -2.6% for beads compared to prescription. Deviations up to -9% were found in cases of large surface irregularity, or with underlying air cavities or bone. Dose shielding by beads could be clinically relevant at low kV energies and superficial depths. CONCLUSIONS: Both film and beads may be used to provide in vivo verification of delivered doses in kV radiotherapy, particularly for complex situations that are not well represented by standard reference condition calculations. PMID- 29173921 TI - Multi-institutional comparison of simulated treatment delivery errors in ssIMRT, manually planned VMAT and autoplan-VMAT plans for nasopharyngeal radiotherapy. AB - PURPOSE: To quantify the impact of simulated errors for nasopharynx radiotherapy across multiple institutions and planning techniques (auto-plan generated Volumetric Modulated Arc Therapy (ap-VMAT), manually planned VMAT (mp-VMAT) and manually planned step and shoot Intensity Modulated Radiation Therapy (mp ssIMRT)). METHODS: Ten patients were retrospectively planned with VMAT according to three institution's protocols. Within one institution two further treatment plans were generated using differing treatment planning techniques. This resulted in mp-ssIMRT, mp-VMAT, and ap-VMAT plans. Introduced treatment errors included Multi Leaf Collimator (MLC) shifts, MLC field size (MLCfs), gantry and collimator errors. A change of more than 5% in most selected dose metrics was considered to have potential clinical impact. The original patient plan total Monitor Units (MUs) were correlated to the total number of dose metrics exceeded. RESULTS: The impact of different errors was consistent, with ap-VMAT plans (two institutions) showing larger dose deviations than mp-VMAT created plans (one institution). Across all institutions' VMAT plans the significant errors included; +/-5 degrees for the collimator angle, +/-5mm for the MLC shift and +1, +/-2 and +/-5mm for the MLC field size. The total number of dose metrics exceeding tolerance was positively correlated to the VMAT total plan MUs (r=0.51, p<0.001), across all institutions and techniques. CONCLUSIONS: Differences in VMAT robustness to simulated errors across institutions occurred due to planning method differences. Whilst ap-VMAT was most sensitive to MLC errors, it also produced the best quality treatment plans. Mp-ssIMRT was most robust to errors. Higher VMAT treatment plan complexity led to less robust plans. PMID- 29173922 TI - On the re-calibration process in radiochromic film dosimetry. AB - PURPOSE: The accuracy and precision of the dose estimates obtained with radiochromic film dosimetry are investigated in a clinical environment. The improvement in the accuracy of dose estimates reached with corrective methods is analyzed. Two novel re-calibration algorithms for radiochromic film dosimetry are presented. METHODS: Two different EBT3 lots are evaluated in two different centres. They are calibrated in Varian linacs and read in two different EPSON scaners. Once the lots are calibrated, three films per lot are considered and divided into stripes that are exposed to known doses. Several dosimetry protocols usually employed in radiochromic film dosimetry are used to convert film responses to absorbed doses. These protocols are characterized by different choices of the film responses or different sensitometric curves. Finally, the accuracy and reproducibility of the dose estimates is investigated with and without the corrective methods. RESULTS AND CONCLUSIONS: The variabilities that affect radiochromic film dosimetry, such as intra-lot variability, inter-scan variability, post-exposure time and film autodevelopment may give rise to inaccuracies in the dose estimates. However, the implementation of re-calibration methods leads to more accurate dose estimates. All the investigated protocols showed more accurate and reproducible results when the re-calibrated methods were employed. So, the novel re-calibration methods may be applied in order to improve the accuracy and reproducibility of radiochromic film dosimetry. PMID- 29173923 TI - Microdosimetry in 3D realistic mitochondria phantoms: Geant4 Monte Carlo tracking of 250keV photons in phantoms reconstructed from microscopic images. AB - Mitochondria are considered to be sensitive radiation targets since they control processes vital to the cell's functioning. These organelles are starting to get attention and some studies are investigating the radiation dose inside them. In previous studies, mitochondria are represented as simple ellipsoids inside the cell not taking into consideration the complexity of their shape. In this study, realistic phantoms are built based on deconvolved widefield fluorescent microscopic images of the mitochondrial networks of fibroblast cells. The phantoms are imported into Geant4 as tessellated volumes taking into account the geometrical complexity of these organelles. Irradiation with 250keV photons is performed and the lineal energy is calculated. The lineal energy distributions inside the produced phantoms are compared with those calculated inside simple volumes, a sphere and an ellipsoid, where the effect of the shape and volume is clearly seen on lineal energies. PMID- 29173924 TI - A review of GPU-based medical image reconstruction. AB - Tomographic image reconstruction is a computationally demanding task, even more so when advanced models are used to describe a more complete and accurate picture of the image formation process. Such advanced modeling and reconstruction algorithms can lead to better images, often with less dose, but at the price of long calculation times that are hardly compatible with clinical workflows. Fortunately, reconstruction tasks can often be executed advantageously on Graphics Processing Units (GPUs), which are exploited as massively parallel computational engines. This review paper focuses on recent developments made in GPU-based medical image reconstruction, from a CT, PET, SPECT, MRI and US perspective. Strategies and approaches to get the most out of GPUs in image reconstruction are presented as well as innovative applications arising from an increased computing capacity. The future of GPU-based image reconstruction is also envisioned, based on current trends in high-performance computing. PMID- 29173925 TI - Nuclear and radiological emergencies: Building capacity in medical physics to support response. AB - Medical physicists represent a valuable asset at the disposal of a structured and planned response to nuclear or radiological emergencies (NREs), especially in the hospital environment. The recognition of this fact led the International Atomic Energy Agency (IAEA) and the International Organization for Medical Physics (IOMP) to start a fruitful collaboration aiming to improve education and training of medical physicists so that they may support response efforts in case of NREs. Existing shortcomings in specific technical areas were identified through international consultations supported by the IAEA and led to the development of a project aiming at preparing a specific and standardized training package for medical physicists in support to NREs. The Project was funded through extra budgetary contribution from Japan within the IAEA Nuclear Safety Action Plan. This paper presents the work accomplished through that project and describes the current steps and future direction for enabling medical physicists to better support response to NREs. PMID- 29173926 TI - Measurement of the influence of titanium hip prosthesis on therapeutic electron beam dose distributions in a novel pelvic phantom. AB - PURPOSE: To investigate the degree of 18 and 22MeV electron beam dose perturbations caused by unilateral hip titanium (Ti) prosthesis. METHODS: Measurements were acquired using Gafchromic EBT2 film in a novel pelvic phantom made out of Nylon-12 slices in which a Ti-prosthesis is embedded. Dose perturbations were measured and compared using depth doses for 8*8, 10*10 and 11*11cm2 applicator-defined field sizes at 95cm source-surface-distance (SSD). Comparisons were also made between film data at 100cm SSD for a 10*10cm2 field and dose calculations made on CMS XiO treatment planning system utilizing the pencil beam algorithm. The extent of dose deviations caused by the Ti prosthesis based on film data was quantified through the dose enhancement factor (DEF), defined as the ratio of the dose influenced by the prosthesis and the unchanged beam. RESULTS: At the interface between Nylon-12 and the Ti implant on the prosthesis entrance side, the dose increased to values of 21+/-1% and 23+/-1% for 18 and 22MeV electron beams, respectively. DEFs increased with increasing electron energy and field size, and were found to fall off quickly with distance from the nylon-prosthesis interface. A comparison of film and XiO depth dose data for 18 and 22MeV gave relative errors of 20% and 25%, respectively. CONCLUSION: This study outlines the lack of accuracy of the XiO TPS for electron planning in highly heterogeneous media. So a dosimetric error of 20-25% could influence clinical outcome.

PMID- 29173929 TI - Lessons Learned from 50 Years of Violence Prevention Activities in the African American Community. AB - PURPOSE: This article covers violence prevention (homicide and suicide) activities in the African American community for nearly 50 years. METHOD: Drawing on lived experience the works of early and recent efforts by African American physicians, the author illustrates we know a great deal about violence prevention in the African American community. RESULTS: There remains challenges of implementation and political will. Further, most physicians, like the public, are confused about the realities of homicide and suicide because of the two different presentations both are given in the media and scientific literature. CONCLUSIONS: Responses to homicide and suicides should be based on science not distorted media reports. There are violence prevention principles that, if widely implemented, could stem the tide of violence. PMID- 29173930 TI - Birth Outcomes in Relation to Intimate Partner Violence. AB - OBJECTIVES: Intimate partner violence (IPV)during pregnancy is a significant public health problem. Approximately 324,000 IPV victimizations occur during pregnancy each year. However, research on the impact of IPV on birth outcomes yields conflicting findings. This study examines the association of IPV with birth outcomes among pregnant women. STUDY DESIGN: We used a retrospective cohort study design to analyze data from chart reviews of a random sample of 1542 pregnant women. These women were seen between 2003 and 2009 at an urban university affiliated prenatal clinic and gave birth at the on-site hospital. Victims of IPV were defined as those who scored equal to or higher than 10 on an IPV screening tool: HITS (Hit, Insult, Threaten, and Scream). Three measures were included in birth outcomes. Preterm delivery was defined as gestational age less than 37 weeks. Low birth weight was defined as infants born weighing <2500 g. Neonatal intensive care was measured by prevalence of receiving intensive care. RESULTS: The prevalence of IPV was 7.5%. Compared to non-abused women, abused women were more likely to have preterm deliveries (18.3% vs. 10.3%; p = .016). Compared to infants of non-victims, infants of victims were more likely to have low birth weight (21.5% vs. 11.0%; p = .003) and to receive neonatal intensive care (23.4% vs. 7.8%; p = .000). Results from multivariate analyses indicated that victims were more likely to have preterm deliveries than non-victims (OR = 1.72; 95% CI: 1.22-2.95). More infants of victims had low birth weight (OR = 2.03; 95% CI: 1.22-3.39) and received neonatal intensive care than those of non victims (OR = 4.04; 95% CI: 2.46-6.61). CONCLUSIONS: Abused pregnant women had poorer birth outcomes compared to non-abused pregnant women. Healthcare providers should be trained to screen and identify women for IPV, and interventions should be designed to reduce and prevent IPV and thereby improve health outcomes for victims and their children. PMID- 29173931 TI - Infant Deaths and Mortality from Gun Violence: Causal or Casual? AB - OBJECTIVE: Describe trends in non-Hispanic black infant mortality (IM) in the New York City (NYC) counties of Bronx, Kings, Queens, and Manhattan and correlations with gun-related assault mortality. METHODS: Linked Birth/Infant Death data (1999 2013) and Compressed Mortality data at ages 1 to >=85 years (1999-2013). NYC and United States (US) Census data for income inequality and poverty. Pearson coefficients were used to describe correlations of IM with gun-related assault mortality and other causes of death. RESULTS: In NYC, the risk of non-Hispanic black IM in 2013 was 49% lower than in 1995 (rate ratio: 0.51; 95% CI: 0.43, 0.61). Yearly declines between 1999 and 2013 were significantly correlated with declines in gun-related assault mortality (correlation coefficient (r) = 0.70, p = 0.004), drug-related mortality (r = 0.59, p = 0.020), major heart disease and stroke (r = 0.85, p < 0.001), malignant neoplasms (r = 0.57, p = 0.026), diabetes mellitus (r = 0.63, p = 0.011), and pneumonia and influenza (r = 0.78, p < 0.001). There were no significant correlations of IM with chronic lower respiratory or liver disease, non-drug-related accidental deaths, and non-gun related assault. Yearly IM (1995-2012) was inversely correlated with income share of the top 1% of the population (r = -0.66, p = 0.007). CONCLUSIONS: In NYC, non Hispanic black IM declined significantly despite increasing income inequality and was strongly correlated with gun-related assault mortality and other major causes of death. These data are compatible with the hypothesis that activities related to overall population health, including those pertaining to gun-related homicide, may provide clues to reducing IM. Analytic epidemiological studies are needed to test these and other hypotheses formulated from these descriptive data. PMID- 29173932 TI - Influence of Intimate Partner Violence (IPV) Exposure on Cardiovascular and Salivary Biosensors: Is There a Relationship? AB - BACKGROUND/PURPOSE: Intimate partner violence (IPV) is a global public health epidemic that initiates/exacerbates health consequences affecting a victim's lifespan. IPV can significantly predispose women to a lifetime risk of developing cardiovascular disease (CVD) due to the effects of stress and inflammation. This study investigates the correlation among IPV exposure, in-vivo CVD events, and inflammatory biomarkers as predictor indices(s) for CVD in female dental patients. METHODS: Of 37 women enrolled in this study, 19 were African-American (AA) and 18 non-African-American (non-AA) and their ages ranged from 19 to 63 years. IPV-exposure and stress-induced in-vivo CVD events such as Chest Pain (CP) and Heart palpitations were recorded from all enrolled subjects. Cardiovascular events were obtained through surveys by patient self-report. Saliva specimens were obtained from all women and were analyzed for CVD biomarkers using multiplex ELISA. RESULTS: The prevalence of IPV was 51% (19/37) and statistically equivalent for AA and non-AA. The results show differences in experience of 1) CP (p < 0.01) and 2) heart palpitations (p < 0.02) when IPV + participants are compared with IPV- AA and non-AA cohorts. Of 10 CVD biomarkers analyzed, significant correlations between IPV+ and IPV- subjects were observed for biomarkers that include Interleukin-1beta/sCD40L; TNFalpha/sCD40L; Myoglobin/IL 1beta; CRP/sCD40L; CRP/IL-6; CRP/TNFalpha; TNFalpha/siCAM; CRP/MMP9; TNF alpha/Adiponectin (p < 0.01). DISCUSSION/IMPLICATIONS: Analysis of in vivo CVD status showed that significant race/health disparities exist in IPV + cohorts, as well as increased expression of inflammatory mediators, specifically CRP, IL 1beta, IL-6, MMP9. Women who have experienced IPV may be a target cohort for primary prevention of CVD. The use of salivary biomarkers and our protocol may provide a less invasive method to help increase identification of victims at risk for IPV and CVD and potentially decrease other health injuries associated with IPV exposure. PMID- 29173933 TI - Elder Abuse in the African Diaspora: A Review. AB - BACKGROUND: As with many other populations, abuse of older adults is a growing problem across the Africa Diaspora. Modernization and urbanization are eroding the traditional values of respect for older adults. Also, older adults living in environments with limited social and economic resources, and having no means of economic support create a recipe for elder abuse and neglect. METHODS: This article reviews the current literature on the epidemiology, risk factors, and interventions used for elder abuse across the African Diaspora. RESULTS: Reports of elder abuse range from 24.9% to 81.1% across the Diaspora. Risk factors include cognitive and physical impairment, social isolation, lack of resources and widowhood. CONCLUSION: Community-based programs using the unique social networks of older populations of African descent can provide a venue to improve caregiver training and support, reinforce traditional filial and informal caregiving practices, increase the utilization of available governmental and institutional. PMID- 29173934 TI - Methods and Findings from the National Violent Death Reporting System for Identifying Gang-Like Homicides, 2005-2008. AB - BACKGROUND: The National Violent Death Reporting System (NVDRS) captures homicides that law enforcement or coroner/medical examiners deem as gang-related but the criteria used may vary across locations. Also, the existing gang-related variable likely underestimates the number of homicides that are associated with gang activity. This study utilizes NVDRS data to identify "gang-like" homicides which are not currently captured as "gang-related." METHODS: A set of criteria recommended by a panel of experts in gang violence, was applied to homicides collected in the NVDRS. These criteria, termed "gang-like" characteristics, were developed in order to better identify homicides consistent with gang activity. The narratives of the identified cases were then reviewed to refine the operational standard. After the reviews were complete, the typology was modified to finalize the operationalization of "gang-like" homicides. RESULTS: A total of 481 gang-like homicides were identified using the "gang-like" criteria. This represents an increase of almost 69% over the 696 gang-related homicides captured in NVDRS dataset. Gang-like and gang-related homicides combined represented 6.6% of homicides that occurred from 2005 to 2008. Among the 16 states included in this analysis, Colorado (15.5%) and Oklahoma (14%) had the highest percentage of homicides that were either gang-related or gang-like. Maryland had the greatest relative increase (227.3%) between gang related and gang-like homicides. CONCLUSION: The new "gang-like" variable complements the existing "gang-related" variable by providing an automated, standardized way to identify homicides that have circumstances consistent with gang activity. This new variable might be useful to states and localities seeking an efficient way to monitor homicides potentially resulting from gang activity. Additional efforts are needed to standardize the reporting of homicides associated with gang activity.

AB - PURPOSE: It is known that racial disparities exist in terms of disease prevalence and access to health care. However, the link between race/ethnicity and sleep quality is often under-recognized. RESULTS: Current evidence shows that differences exist between Blacks and Whites in terms of sleep duration, sleep quality, and the likelihood of acquiring a sleep disorder. It has been argued that the adverse effects of ethnicity on sleep quality or duration interact with other social or personal factors (such as employment) and that the effects of these factors are interactive and need to be analyzed simultaneously. There is a growing body of evidence showing that disturbed sleep is a mediator of the effect of environmental stressors on personal health, which is more pronounced in ethnic minorities. CONCLUSIONS: These findings support the notion that perceived discrimination or unfair treatment has significant associations with complaints of sleep disturbance and disturbed objective measures of sleep quality and sleep architecture. Hence, greater efforts are needed to demonstrate how racial/ethnic factors influence different sleep processes. PMID- 29173936 TI - Factors Perceived to Influence the Decision for African Americans to Become Registered Organ Donors at the Department of Motorized Vehicles. AB - BACKGROUND: African Americans (AA) are a third as likely as Caucasians to become registered organ donors at the Department of Motorized Vehicles (DMV). The Department of Health and Human Services has set the goal that at least 50% of adults in each state are registered donors. AIMS: The purpose of this study was to explore the personal, behavioral and environmental factors associated with AA donor registration decision-making at the DMV. METHODS: Guided by the Social Cognitive Theory, 13 focus groups (n = 100 participants) were conducted with AAs within 3 months of visiting a DMV and making a decision regarding whether to become or to not become a registered donor. The data were analyzed using inductive thematic and qualitative content analyses. RESULTS: Study participants expressed a desire to learn more information while waiting in line at the DMV. Knowing a family member or friend in need of an organ transplant, and the desire to make one's own decision were two salient factors associated with the decision to become a registered organ donor. Several aspects of the DMV environment (e.g., noisy, overcrowded, lacking privacy) were cited as deterrents to becoming a registered donor. DISCUSSION: This study highlights the personal, behavioral and environmental factors associated with AA organ donor registration decision-making at the DMV. CONCLUSION: The DMV is a setting where many adults make a decision about organ donation. Policies that create an environment in the DMV to support informed decision-making (e.g., privacy, informed clerks, available educational materials, etc.) are indicated. PMID- 29173937 TI - Relationship between Ultrasonic Marker of Fetal Lung Maturity and Lamellar Body Count. AB - BACKGROUND: The aim of this study was prediction the fetal lung maturity by ultrasonic markers and comparison by lamellar body count and fetal outcome. METHODS: A prospective Longitudinal study Department of perinatology of performed Emam Khomeini hospital and Mirza Kochak Khan Hospital in Tehran, Iran from March 2013 to January 2014. 100 pregnant women (37-40 weeks of gestation) who were admitted for elective cesarean section and referred for an obstetric ultrasound scan at the same day of their elective cesarean section were included. Scanning with linear ultrasound with convex transducer frequency of 3.5 MHZ was utilized to measure the biparietal diameter, Amniotic fluid vernix and placental grading. Statistical analysis was performed using Spss version 20. Validity of the indicators compared with lamellar body count and fetal outcome. RESULTS: In this study, from 100 patients under study, 8 cases were hospitalized in NICU (neonatal intensive care unit) which all of them had LAMELAR BODY COUNT < 14000 (10000 14000). There were 6 boys and 2 girls. In this study, there was no perinatal mortality. CONCLUSIONS: In study we used ultrasonic marker of fetal lung maturity and related this to lamellar body count and neo natal outcome. The ultrasonic marker of fetal lung maturity can reduce mortality and morbidity in neonate. PMID- 29173938 TI - Evaluation of Incidental Thyroid Nodules in Cancer Patients. AB - OBJECTIVE: Frequency of thyroid cancer in incidental thyroid nodules identified by imaging techniques in cancer patients is higher than that in the normal population. In the retrospective study, we have both investigated the incidence of thyroid cancer in incidentally identified nodules and compared the imaging techniques to determine whether there is any difference between them in detection of malign nodules. METHODS: A total of 7319 patients who underwent thyroid fine needle aspiration biopsy (FNAB) were included in the study. The data of 174 patients who had previously been diagnosed with a hematologic or solid malignancy prior to the FNAB procedure and had incidentally identified thyroid nodules were evaluated retrospectively. RESULTS: Eighty-six (49.5%) of the incidental nodules were identified with ultrasonography (USG), 62 (35.6%) with positron emission tomography (PET) or PET/computed tomography (PET/CT), and 26 (14.9%) with CT. As a result of thyroidectomy, papillary carcinoma was identified in 8 (4.6%) patients, and metastasis to the thyroid of a primary cancer was found in 3 (1.7%) patients. While the papillary carcinoma proportion in the nodules identified by USG was 3.4%, PET/CT was 8.9%. A cut-off maximal standardized uptake value of 11.6 in PET/CT indicated malignancy achieving a sensitivity of 83.3% and a specificity of 91.1%. CONCLUSION: Whether the nodule in the incidental thyroid nodules of cancer patients is identified using USG or PET/CT, the risk of thyroid cancer is similar. However, cancer risk is higher in the event of a higher focal uptake in the nodules identified by PET/CT. PMID- 29173939 TI - Wire rope tension control of hoisting systems using a robust nonlinear adaptive backstepping control scheme. AB - This paper concerns wire rope tension control of a double-rope winding hoisting system (DRWHS), which consists of a hoisting system employed to realize a transportation function and an electro-hydraulic servo system utilized to adjust wire rope tensions. A dynamic model of the DRWHS is developed in which parameter uncertainties and external disturbances are considered. A comparison between simulation results using the dynamic model and experimental results using a double-rope winding hoisting experimental system is given in order to demonstrate accuracy of the dynamic model. In order to improve the wire rope tension coordination control performance of the DRWHS, a robust nonlinear adaptive backstepping controller (RNABC) combined with a nonlinear disturbance observer (NDO) is proposed. Main features of the proposed combined controller are: (1) using the RNABC to adjust wire rope tensions with consideration of parameter uncertainties, whose parameters are designed online by adaptive laws derived from Lyapunov stability theory to guarantee the control performance and stability of the closed-loop system; and (2) introducing the NDO to deal with uncertain external disturbances. In order to demonstrate feasibility and effectiveness of the proposed controller, experimental studies have been conducted on the DRWHS controlled by an xPC rapid prototyping system. Experimental results verify that the proposed controller exhibits excellent performance on wire rope tension coordination control compared with a conventional proportional-integral (PI) controller and adaptive backstepping controller.

AB - OBJECTIVE: This study explored the feasibility of using a 23-week subsidized community-supported agriculture program to increase access to and intake of vegetables among Federally Qualified Health Center patients. METHODS: Outcomes were measured using pre-post intervention surveys (n = 9). Process data were collected in post-intervention surveys and focus groups (n = 15). RESULTS: Most participants (77%) indicated that the program improved their health and all (100%) reported that they were eating a greater variety of vegetables because of their participation in the program. Three themes emerged from the focus groups: increased access to fresh and/or organic vegetables, improved diet quality, and the importance of social support during the program. CONCLUSIONS AND IMPLICATIONS: Linking subsided community-supported agriculture programs with Federally Qualified Health Centers has the potential to increase access to and intake of vegetables among low-income patients. However, further research is needed with a larger sample size and a more robust study design. PMID- 29173942 TI - Establishing consensus on survey measures for electronic nicotine and non nicotine delivery system use: Current challenges and considerations for researchers. AB - The development and validation of survey measures for electronic nicotine and non nicotine delivery system (ENDS) use has not kept pace with the burgeoning research on them. This, along with the diverse and evolving nature of ENDS, presents several unique measurement challenges and hampers surveillance and tobacco regulatory research efforts. In this commentary, we identify four important areas related to ENDS use (describing ENDS products; defining current use; evaluating frequency and quantity of use; and characterizing devices and e liquids) and summarize a selective review of the measurement and definitions of these constructs across prominent national tobacco use surveys and 30 projects within the 14 federally-funded Tobacco Centers of Regulatory Science. Across these national, regional, and local studies, there was considerable variability and relatively little consensus in ENDS use measures - thus highlighting the need for caution when comparing findings across studies or over time until more research is available to evaluate the sensitivity of findings to differing measures. Drawing from the nascent ENDS use measurement research literature and our experiences, we conclude with general considerations for measuring ENDS use for tobacco researchers as an initial step towards the development of consensus measures.

Some of them showed significant antiviral action against hepatitis C virus (HCV), herpes simplex (HCV-1) and influenza A virus comparable to that of ribavirin itself. The data obtained confirm the proposed theory of the ribavirin possible antiviral activity mechanism related with bioisosterism. PMID- 29173945 TI - Synthesis and in vitro evaluations of 6-(hetero)-aryl-imidazo[1,2-b]pyridazine-3 sulfonamide's as an inhibitor of TNF-alpha production. AB - Tumor necrosis factor-alpha is an important pro-inflammatory cytokine having a key role in hosts defensive process of immune systems and its over expression led to a diverse range of inflammatory diseases such as Rheumatoid arthritis, Cronh's disease, psoriasis, etc. This paper describes our medicinal chemistry efforts on imidazo[1,2-b]pyridazine scaffold: design, synthesis and biological evaluation. By the introducing sulfonamide functionality at 3 positions and substituting 6 positions with (hetero)-aryl groups', a small library of compounds was prepared. All synthesized compounds were screened for lipopolysaccharide (LPS) mediated TNF alpha production inhibitory activity. Biological data revealed that the majority of the compounds of this series showed moderate to potent TNF-alpha production inhibitory activity. Compound 5u and 5v are the most potent compounds from the series with activity of IC50 = 0.5 uM and 0.3 uM respectively. A short SAR demonstrates that 3-sulfonyl-4-arylpiperidine-4-carbonitrile moiety on imidazo[1,2-b]pyridazine showed better activity compared to the 3-(4 aryllpiperazin-1-yl) sulfonyl) in hPBMC assay. The molecular modeling studies revealed that the potent TNF-alpha production inhibitory activity 5v due to the extra stability of complex because of an extra pi-pi (pi-pi) stacking, hydrogen bonding interactions.

AB - The purpose of this study was to develop a novel and cost-effective thin-layer chromatographic method (TLC) using cellulose powder as stationary phase for authentication of the selected fruit-based alimentary products and targeting anthocyanes as the authenticity markers. Our method outperformed the HPTLC method earlier developed by another research team using silica gel as stationary phase. It was demonstrated that due to a limited chemical stability of anthocyanes, employing them as authenticity markers is burdened with a non-negligible uncertainty risk. Hydrolytic split of the glycosides into the aglycone and carbohydrate moieties can lead to a confusing multiplication of chromatographic bands and therefore it is advisable to use for the authentication purposes a limited set of well selected and stable enough anthocyane markers. Cyanin chloride, keracyanin chloride, pelargonidin chloride and delphinidin chloride were selected as the external standards and for the development of the calibration curves. The TLC-obtained LOD and LOQ values were 0.025 and 0.075MUgspot-1 for cyanin, 0.055 and 0.166MUgspot-1 for keracyanin, 0.047 and 0.140MUgspot-1 for pelargonidin, and 0.171 and 0.513MUgspot-1 for delphinidin, respectively. The analogous HPTLC-obtained LOD and LOQ values were 0.107 and 0.321MUgspot-1 for cyanin, 0.189 and 0.566MUgspot-1 for keracyanin, and 0.161 and 0.484MUgspot-1 for pelargonidin, respectively. Delphinidin was not detectable with use of the HPTLC method. Consequently, quantification of anthocyanes in the alimentary products carried out with use of TLC allowed identification of more target compounds and in a higher number of alimentary products than it was possible with use of HPTLC, apparently due to the LOD levels by one magnitude order lower for TLC than HPTLC. PMID- 29173955 TI - Speedy standing wave design and simulated moving bed splitting strategies for the separation of ternary mixtures with linear isotherms. AB - Simulated Moving Bed (SMB) has advantages over batch chromatography in terms of productivity and solvent efficiency. However, SMB applications in large scale production are still limited because of the many design parameters that must be specified and the multiple splitting strategies that can be implemented. To overcome these barriers, this study extends the Speedy Standing Wave Design (SSWD) method of Weeden and Wang for binary linear systems to ternary linear adsorption systems. The dimensionless operating parameters, sorbent productivity, and solvent efficiency can be quickly calculated without process simulations. SSWD also gives an overview of the productivity and solvent efficiency as a function of two key dimensionless groups. This overview can be used for optimization of separation costs and for comparison of splitting strategies. The SSWD method was verified using rate model simulations for the separation of three amino acids. The simulated yields agree with the SSWD target yields within 1% for all components. The example was also used to illustrate the key design rules for ternary separations. High productivity and solvent efficiency can be achieved with a large difference in the retention factors of the heavy key and light key, which are the components that define the split of the feed between extract and raffinate products. For ternary ideal systems, solvent efficiency is inversely proportional to the largest difference in retention factors. For this reason, minimizing the overall range of retention factors can significantly improve the solvent efficiency and product concentration without sacrificing productivity. If more than one SMB is needed, the easiest split should be done first for higher productivity, solvent efficiency, and product concentration. In the example case study, both the productivity and solvent efficiency were about an order of magnitude higher when the easiest split was done in the first ring. The SSWD method can be used to design a wide array of multi-component separations with high yield, productivity, and solvent efficiency.

AB - Chiral separation has been a remarkably active area of research over the past long time and it still stays that way. Over the last few decades, counter-current chromatography (CCC) was successfully applied to the field of chiral separation. It provides an attractive approach to obtain pure enantiomer, particularly in preparative application because of its unique advantages of high load capacity, low solvent consumption and easy scale-up. The last several years great strides have been made in chiral separation by CCC, ranging from novel elution modes such as recycling elution mode and multiple dual mode elution to more specialized approaches such as pH-zone-refining and biphasic chiral recognition technologies. These developments have greatly improved the resolution of enantiomers and promoted the application of CCC in the field of chiral separation. Although not as popular as its application to the field of separation of natural product, the development of chiral separation by CCC should not be underrated. In this review article, we refer to the development, applications and future outlook of chiral separation by CCC, with emphasis on topics of its history, mechanism, advantages, limitations, current development and challenges. Meanwhile, its orientation of continued evolution and future outlook also have been discussed. While some scientific and technological problems have not yet been solved thoroughly, chiral separation by CCC has demonstrated potential advantages and prospects in this field and has good chance at preparative enantioseparation. PMID- 29173958 TI - Ion-pairing reversed-phase chromatography coupled to inductively coupled plasma mass spectrometry as a tool to determine mercurial species in freshwater fish. AB - Most of analytical community is focused on reversed phase high performance liquid chromatography (RP-HPLC) for mercury speciation by employing mobile phases comprising of high salts and moderate amounts of organic solvents. This study aims at rapid mercury speciation analysis by ion-pairing RP-HPLC with inductively coupled plasma mass spectrometry (ICP-MS) detection only using low salts for the sake of green analytical chemistry. Two ion-pairing HPLC methods were developed on individual usage of positively and negatively charged ion-pairing reagents (tetrabutylammonium hydroxide -TBAH and sodium dodecylbenzene sulfonate -SDBS), where sodium 3-mercapto-1-propysulfonate (MPS) and l-cysteine (Cys) were individually added in mobile phases to transform mercury species into negative and positive Hg-complexes for good resolution. Addition of phenylalanine was also utilized for rapid baseline separation in combination of short C18 guard columns. Optimum mobile phases of 2.0mM SDBS+2.0mM Cys+1.0mM Phe (pH 3.0) and 4.0mM TBAH+2.0mM MPS+2.0mM Phe (pH 6.0) both achieved baseline separation of inorganic mercury (Hg2+), methylmercury (MeHg), ethylmercury (EtHg) and phenylmercury (PhHg) on two consecutive 12.5-mm C18 columns. The former mobile phase was selected for mercury speciation in freshwater fish because of short separation time (3.0min). Detection limits of 0.015 for Hg2+, 0.014 for MeHg, 0.028 for EtHg and 0.042MUgL-1 for PhHg were obtained along with satisfactory precisions of peak height and area (1.0-2.8% for 5.0MUgL-1 Hg-mixture standard). Good accordance of determined values of MeHg and total mercury in certified reference materials of fish tissue (GBW 10029) and tuna fish (BCR-463) with certified values as well as good recoveries (91-106%) proved good accuracy of the proposed method. An example application to freshwater fish indicated its potential in routine analysis, where MeHg was presented at 3.7-20.3MUgkg-1 as the dominate species. PMID- 29173959 TI - Aspects influencing patients' preferences for the management of drug-drug interactions: A focus group study. AB - OBJECTIVE: The management of drug-drug interactions (DDIs) involves a complex risk-benefit assessment, in which patients' preferences should be taken into account. The aim of this study was to examine the aspects influencing patients' preferences with regard to DDI management options. METHODS: A qualitative study consisting of five focus groups with patients chronically using cardiovascular drugs was conducted. Key questions concerned preferences regarding DDI management options for a provided fictitious DDI. Thematic analysis of the verbatim transcripts was performed. RESULTS: Despite their limited knowledge with respect to DDIs, patients easily chose a management option for the presented DDI. When additional information was provided, preferences showed to be fluid. Ten interdependent aspects influencing preferences were derived from patients' argumentations: risk perception, fear, acceptance of uncertainty, openness to change, willingness to take risk, trust in health care professional, financial & practical burdens, health condition, experience, and knowledge & assumptions. CONCLUSION: Patients' preferences regarding DDI management options were often determined by provided information. Preferences were dependent on an interplay of diverse aspects. PRACTICE IMPLICATIONS: Tailored provision of information and individualized counseling is needed for active patient involvement in DDI decision making.

Canada's unique health system, population distribution, and cultural context suggest there is value in addressing the topic in the Canadian context. We conducted a scoping review to synthesize recent Canadian literature to inform practice in primary care settings and identify research agendas for patient-provider communication in Canada. METHODS: Using Arksey and O'Malley's framework we searched four literature databases: Medline, Web of Science, CINAHL and EMBASE. We extracted 21,932 articles published between 2010 and 2017. A total of 108 articles met the inclusion criteria. The articles were analyzed qualitatively using thematic analysis to identify major themes. RESULTS: Four major themes were identified: information sharing, relationships, health system challenges, and development and use of communication tools. CONCLUSION: Our review identified a need for Canadian research regarding: communication in primary care with Aboriginal, immigrant, and rural populations; the impact of medical tourism on primary care; and how to improve communication to facilitate continuity of care. PRACTICE IMPLICATIONS: Challenges providers face in primary care in Canada include: communicating with linguistically and culturally diverse populations; addressing issues that emerge with the rise of medical tourism; a need for decision aids to improve communication with patients. PMID- 29173961 TI - Direct adaptive robust tracking control for 6 DOF industrial robot with enhanced accuracy. AB - A direct adaptive robust tracking control is proposed for trajectory tracking of 6 DOF industrial robot in the presence of parametric uncertainties, external disturbances and uncertain nonlinearities. The controller is designed based on the dynamic characteristics in the working space of the end-effector of the 6 DOF robot. The controller includes robust control term and model compensation term that is developed directly based on the input reference or desired motion trajectory. A projection-type parametric adaptation law is also designed to compensate for parametric estimation errors for the adaptive robust control. The feasibility and effectiveness of the proposed direct adaptive robust control law and the associated projection-type parametric adaptation law have been comparatively evaluated based on two 6 DOF industrial robots. The test results demonstrate that the proposed control can be employed to better maintain the desired trajectory tracking even in the presence of large parametric uncertainties and external disturbances as compared with PD controller and nonlinear controller. The parametric estimates also eventually converge to the real values along with the convergence of tracking errors, which further validate the effectiveness of the proposed parametric adaption law.

AB - INTRODUCTION: The intact lateral wall plays a key role in stabilization of trochanteric fracture. Hence extreme precaution should be taken to prevent lateral wall damage during DHS fixation. Present study is aimed at evaluating the determinants of lateral wall fracture and its effect on outcome in intertrochanteric fracture femur treated with DHS. MATERIAL AND METHODS: This is a prospective study involving intertrochanteric fractures treated with DHS fixation from July 2013 to June 2014. Out of 135 patients 49(36.3%) had stable fractures and 86(63.7%) unstable fractures. Cortical thickness index (CTI) was measured to evaluate osteoporosis. Lateral wall thickness in anteroposterior radiograph was also measured.All patients underwent 135 degrees DHS fixation.Postoperative x-rays are assessed for implant position, intactness of the lateral wall, tip apex distance (TAD) and medialization. Functional outcome was measured at the end of fracture union by modified Harris hip score and Parkers mobility score. Clinical information including age, gender, fracture classification, TAD, lateral wall thickness and functional outcome of the patients were subjected to statistical analysis. RESULTS: 34 (19.5%) patients had lateral wall fractures. Medialization was found in 22 out of these 34 (64.7%) patients. The mean preoperative lateral wall thickness of these patients is 19.2mm, compared with 26.8mm in patients with intact lateral wall (p<0.001). The mean values of CTI and TAD are comparable in both the groups. In patients with intact lateral wall, mean Harris hip score is 73.1 compared to 65.5 in lateral wall fracture group (p<0.001). Preinjury mobility status was achieved in 70.2% of intact lateral wall patients, whereas only 32.3% (11) achieved that in lateral wall fracture group. Threshold for lateral wall thickness that could predict lateral wall fracture was found to be 21mm with 95% sensitivity and 88.2% specificity. CONCLUSION: Lateral wall fractures during DHS fixation are not uncommon and osteoporosis has no bearing on its occurrence. It alone can lead to poor radiological and functional outcome independent of TAD. Lateral wall thickness is a reliable predictor of intra operative lateral wall fracture during DHS fixation and nailing is a good option especially when lateral wall thickness is <21mm. PMID- 29173963 TI - Acute Kidney Injury: It's not just the 'big' burns. AB - BACKGROUND: Acute Kidney Injury (AKI) complicates the management of at least 25% of patients with severe burns and is associated with long term complications. Most research focuses on the patients with more severe burns, and whether the same factors are associated with the development of AKI in patients with burns between 10 and 19% total body surface area (TBSA) is unknown. The aims of this study were to examine the incidence of, and factors associated with, the development of AKI in patients with %TBSA>=10, as well as the relationship with hospital metrics such as length of stay (LOS). METHODS: Retrospective medical record review of consecutive burns patients admitted to The Alfred Hospital, the major adult burns centre in Victoria, Australia. Demographic and injury details were recorded. Factors associated with AKI were determined using multiple logistic regression. RESULTS: Between 2010 and June 2014, 300 patients were admitted with burn injury and data on 267 patients was available for analysis. Median age was 54.5 years with 78% being male. Median %TBSA was 15 (IQR 12, 20). The AKI incidence, as measured by the RIFLE criteria, was 22.5%, including 15% (27/184) in patients with %TBSA 10-19. Factors associated with AKI included increasing age and %TBSA (OR 1.05 p<0.001) as well as increased surgeries (p<0.041) and a cardiac comorbidity (p<0.01). All patients with renal comorbidity developed AKI. In the %TBSA 10-19 cohort, only increasing age (OR 1.05 p<0.001) was associated with AKI. After accounting for confounding factors, the probability of discharge from hospital in Non-AKI group was greater than for the AKI patients at all time points (P<0.001). CONCLUSION: This is the first study to show an association between patients with %TBSA 10-19 and AKI. Given the association between AKI and complications, prospective research is needed to further understand AKI in burns with the aim of risk reduction. PMID- 29173964 TI - Outcomes after resection versus non-resection management of penetrating grade III and IV pancreatic injury: A trauma quality improvement (TQIP) databank analysis. AB - BACKGROUND: High-grade traumatic pancreatic injuries are associated with significant morbidity and mortality. Non-resection management is associated with fewer complications in pediatric patients. The present study evaluates outcomes following resection versus non-resection management of severe pancreatic injury caused by penetrating trauma. METHODS: A retrospective study of the Trauma Quality Improvement Program (TQIP) database was performed from 1/2010 to 12/2014. Patients with AAST Organ Injury Scale pancreatic grade III and IV injuries caused by penetrating trauma were included in the study. Demographics, vital signs on admission, Abbreviated Injury Scale per body region, Injury Severity Score, transfusion and therapeutic modality were obtained. Mortality, length of stay (LOS), pseudocyst, pancreatitis, sepsis, thromboembolism, renal failure, ARDS and unplanned ICU admission or re-operation were stratified according to injury grade and treatment modality. Patients were stratified into those who did/did not undergo pancreatic resection. RESULTS: A total of 4,098 patients had a pancreatic injury of which 15.9% (n=653) had a grade III and 6.7% (n=274) a grade IV pancreatic injury. There were no differences in patient demographics or overall injury severity between the resected and non-resected cohorts within each pancreatic injury grade. Forty-two percent of grade III and 38.0% of grade IV injuries underwent pancreatic resection. The total LOS was longer in the resection arm irrespective of pancreatic injury severity. There was no significant difference in morbidity between cohorts. Similarly, mortality was not significantly different between the two management approaches for grade III: 15.1% (95% CI 11.0-19.9) vs. 18.4% (95% CI 14.6-22.6), p=0.32 and grade IV: 24.0% (95% CI: 16.2-33.4) vs. 27.1% (95% CI: 20.5-34.4), p=0.68. CONCLUSION: Resection for treatment of grade III and IV pancreatic injury is not associated with a significant decrease in mortality but is associated with an increase in hospital LOS. PMID- 29173965 TI - Complications and patient-injury after ankle fracture surgery. -A closed claim analysis with data from the Patient Compensation Association in Denmark. AB - BACKGROUND: The Patient Compensation Association (PCA) receives claims for financial compensation from patients who believe they have sustained damage from their treatment in the Danish health care system. In this study, we have analysed closed claims in which patients suffered injuries due to the surgical treatment of their ankle fracture. We identified causalities contributing to these injuries and malpractices, as well as the economic consequences of these damages. METHODS: Fifty-one approved closed claims from the PCA database from the years 2004-2009 were analysed in a retrospective systematic review. All patients were adults with an iatrogenic injury, and received compensation. A root cause analysis was performed to identify whether the patient suffered the damage preoperatively, during surgery or postoperatively, and to determine the level of education of the injurious doctor. Economic compensation, co-morbidities and end-result complications were registered. RESULTS: In 9 of the cases the injuries happened preoperatively, but the majority of the injuries, namely 34 occurred during surgery. In 21 of the cases the damage happened postoperatively. Thirty percentages of the patients were mistreated in more than one phase. Level of competence was medical specialists in 2/3 and junior doctors in 1/3 of the cases. In the preoperative phase both groups were equally responsible for the inflicted damage. In the perioperative- and postoperative group, medical specialists inflicted the majority of damages. General recommendations regarding ORIF were not followed in 21/49 of the perioperative damages. The pronation fracture was the most common. The patients received a total average compensation of 17.561 USD each. CONCLUSION: Managing the complex ankle fracture, requires considerable experience. This study indicates that extra attention should be paid to the most technically demanding fractures as the pronation-external-rotation-, diabetic- and fragility fractures. Surgeons should follow the recommendations for ORIF. Emphasis should also focus on adequate postoperative plans. This study finds a high readmission-burden, re-operation rate and great expenses in form of compensation.

AB - The discovery of the lactate-polymerizing enzyme (LPE) enabled the biosynthesis of a polyhydroxyalkanoate (PHA) containing 2-hydroxyalkanoate (2HA). Amino acids are potential precursors of 2HA with various side chain structures if appropriate enzymes are used to convert amino acids to 2HA-coenzyme A (CoA) as the substrate for LPE. In this study, the suitability and utility of (R)-2-hydroxy-4 methylvalerate (2H4MV) dehydrogenase (LdhA) and 2H4MV-CoA transferase (HadA) from Clostridium difficile as 2HA-CoA-supplying enzymes were investigated. By expressing LPE, LdhA, and HadA in Escherichia coli DH5alpha, we successfully produced poly(3-hydroxybutyrate-co-2HA) [P(3HB-co-2HA)] from a related or unrelated carbon source. The 2HA units incorporated into PHA from unrelated carbon sources were primarily 2H4MV and 2-hydroxy-3-phenylpropionate (2H3PhP), which were assumed to be derived from endogenous leucine and phenylalanine, respectively. Furthermore, P(3HB-co-22 mol% 2HA) synthesis was demonstrated by means of saccharified sugars, which are an abundant and renewable feedstock for polymer production from hemicellulosic biomass (Japanese cedar) as the carbon source. Our study shows that several types of 2HA units such as 2H4MV and 2H3PhP are endogenous monomers for PHA biosynthesis in E. coli expressing LdhA and HadA.

AB - Influenza is a major global public health problem, with serious outcomes that can result in hospitalization or even death. We investigate the causal relationship between human influenza cases and air pollution, quantified by ambient fine particles <2.5MUm in aerodynamic diameter (PM2.5). A modified Granger causality test is proposed to ascertain age group-specific causal relationship between weekly influenza cases and weekly adjusted accumulative PM2.5 from 2009 to 2015 in 11 cities and counties in Taiwan. We examine the causal relationship based on posterior probabilities of the log-linear integer-valued GARCH (generalized autoregressive conditional heteroscedastic) model with covariates, which enable us to handle characteristics of influenza data such as integer-value, lagged dependence, and over-dispersion. The resulting posterior probabilities show that the adult age group (25-64) and the elderly group in New Taipei in the north and cities in southwestern part of Taiwan are strongly affected by ambient fine particles. Moreover, the elderly group is clearly affected in all study sites. Globalization and economic growth have resulted in increased ambient air pollution (including PM2.5) and subsequently substantial public health concerns in the West Pacific region. Minimizing exposure to air pollutants is particularly important for the elderly and susceptible individuals with respiratory diseases.

PMID- 29173971 TI - Beyond bystanders: Myeloid cells in chronic lymphocytic leukemia. AB - Tumor-promoting inflammation and escape from immune-mediated tumor destruction have been recognized as hallmarks of cancer, and myeloid cells are key players in these processes. By exploiting the tremendous plasticity of myeloid cells, tumors induce a variety of tumor-supportive and immunosuppressive cell phenotypes like tumor-associated macrophages (TAMs) and myeloid-derived suppressor cells (MDSCs). The relevance of these cell types in hematopoietic malignancies has only recently gained a stronger attention. Chronic lymphocytic leukemia (CLL) is a malignancy of mature B cells that expand in secondary lymphoid organs and the bone marrow, and accumulate in the blood of patients. A large body of evidence suggests that the interactions between CLL cells and non-malignant cells in the tumor microenvironment play a key role in the pathology of this disease. CLL is associated with an inflammatory milieu and defective immune responses. A severe skewing of myeloid and T cells toward leukemia-supportive and immunosuppressive phenotypes have been observed in patient samples and the EMU-TCL1 mouse model of CLL. Myeloid cells were thereby shown to enhance survival of CLL cells and contribute to apoptosis-resistance, to suppress anti-tumoral immunity, and to be involved in immune deficiency of leukemia patients. In addition, treatment regimens that are currently used for CLL target not only directly the malignant cells, but have also an impact on non-malignant bystander cells, including myeloid cells. This review summarizes current literature on these aspects and gives a perspective on how our current knowledge might be used to design novel immunotherapeutic approaches that can be combined with CLL-targeting drugs to achieve better therapeutic responses in CLL patients.

PMID- 29173975 TI - [Non eligibility criteria for hematopoietic stem cell donors: Guidelines from the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM TC)]. AB - The evolution of HLA typing and transplantation techniques makes it easier to identify a donor for hematopoietic stem cell (HSC) transplantation. This activity, strongly regulated by regulatory or normative texts, implies in addition biological, medical, para-medical and sometimes psychological evaluations. The benefit/risk discussion is complicated because it must take into account the benefit/risk ratio for the recipient, and the donor risk. No Evidence Based Medicine data is available and serious events are very rare situations. Biovigilance declarations and their analysis are of fundamental importance. Certain obvious and definite contraindications could be detected very early in the process. It is important to assess whether a risk factor or pathology contributes to increasing the risk associated with collection. In case of recipient risk, the situation should be discussed with the patient team. These recommendations focus on adult peripheral blood HSC donors. They refer to donor information, confidentiality of exchanges, the impact of moral or material pressures, declarations of biovigilance, collegiality and traceability of difficult decisions, desirable experience and training for doctors in charge, use of expert advice informed by an explicit exchange on the possible risks, parsimony of therapeutic interventions and minimization of risks for the donor. We also recommend creation, availability and use by the community of tools and documents (registries, questionnaires, synthetic recommendations, feedback, and collegial qualification meetings) useful for practice.

AB - INTRODUCTION: This multicenter phase 2 study assessed the combination of estramustine and weekly paclitaxel with metastatic castration-resistant prostate cancer (CRPC). PATIENTS AND METHODS: We enrolled 77 patients who had received no prior chemotherapy for CRPC between 1998 and 2000; a total of 74 subjects were eligible for the study. Each 8-week cycle included paclitaxel 90 mg/m2 provided intravenously weekly for 6 weeks, followed by 2 weeks off therapy and oral estramustine 280 mg twice daily for 3 days beginning 24 hours before the first dose of paclitaxel. The primary end point was rate of objective or prostate specific antigen (PSA) response at 16 weeks. A 50% response rate was considered of further interest. RESULTS: Eligible patients received a median of 3 cycles (range, 1-10 cycles). The response rate among patients with measurable disease was 34% (95% confidence interval [CI], 19-52). The PSA response rate was 58% (95% CI, 47-70). Clinical benefit rate was 45% (95% CI, 33-57). The median progression free survival was 5.9 months (95% CI, 4.4-6.7). The median overall survival was 17.6 months (95% CI, 14.6-20.8). The most common clinical grade 3/4 toxicities were fatigue (14%) and sensory neuropathy (7%). Grade 3/4 hematologic toxicities included lymphopenia (21%) and anemia (9%). There was one toxicity-related death. Quality-of-life scores improved by week 8, but the change was not statistically significant. CONCLUSION: The combination has activity defined by PSA declines in CRPC but did not meet the protocol-specified end point for efficacy as defined by objective response rate. Since this study was conducted, more effective, better tolerated regimens have been developed.

AB - Endometrial cancer (EC) is a major source of morbidity and mortality in women worldwide. In France, in 2015, EC was the first gynecological cancer in terms of incidence. Its prognosis is considered favorable because it is most often limited to the uterus at diagnosis. Nevertheless, it is a heterogeneous pathology and 5 year overall survival can vary from 92 % to 42 % in FIGO stage I depending on its histological characteristics. This great heterogeneity leads to important disparities in its surgical management as well as in indications for adjuvant therapies. A consensus conference including three different European learned societies (ESMO-ESGO-ESTRO) has recently established new recommendations in order to standardize its management. One of the main points is the emergence of a new subgroup of patients at risk of recurrence (high-intermediate risk group). Concerning nodal staging, indications are still somewhat blurred for intermediate and high-intermediate risk groups. The sentinel lymph node biopsy remains an experimental procedure in contrast with American guidelines. Concerning adjuvant therapies, the place of chemotherapy and its combination with external beam radiotherapy should be explored, especially for patients with high risk EC and for certain histological subtypes.

PMID- 29173982 TI - Silencing of CEMIP suppresses Wnt/beta-catenin/Snail signaling transduction and inhibits EMT program of colorectal cancer cells. AB - Cell migration inducing hyaluronan binding protein (CEMIP) is a hyaluronic acid binding protein, the abnormal elevation of which is suggested as a contributor in the carcinogenesis of colorectal cancer (CRC). Cancer cells lose their adhesive properties and acquire an enhanced mobility by undergoing epithelial-mesenchymal transition (EMT). This study is performed to investigate whether and how CEMIP orchestrates the EMT process of CRC cells. To avoid the unexpected off-target effects possibly caused by one single shRNA, two shRNAs targeting different mRNA regions of CEMIP gene were used to knock down the mRNA and protein expression of CEMIP. Our data showed that the proliferation, migration and invasion of two CRC cell lines, HCT116 and SW480 cells, were inhibited by CEMIP shRNA. We here defined EMT as the complete or partial loss of E-cadherin and zona occludens protein 1 (ZO-1) (epithelial markers) and the gain of Vimentin and N-cadherin (mesenchymal markers), and found that the EMT process was attenuated in CEMIP silenced SW480 cells. Snail, a direct target of beta-catenin/T cell factor complex, is known to activate the EMT program during cancer metastasis. CEMIP shRNA was further found to suppress the Wnt/beta-catenin/Snail signaling transduction in CRC cells as manifested by the decreased nuclear beta-catenin and Snail. Collectively, our work demonstrates that CEMIP contributes to metastatic phenotype of CRC cells in vitro. PMID- 29173983 TI - [How to explain glomerular filtration rate decrease in intra-abdominal hypertension?] AB - Intra-abdominal hypertension (IAH) is a frequent and serious condition affecting critical care patients. IAH diagnostic needs intravesical pressure (IVP) measurement which is recommended for monitoring patients presenting IAH risk factors. IVP monitoring is probably insufficient in daily practice. This could be explained by lack of knowledge about IAH physiopathology, which leads to absence of therapeutic target. Acute kidney injury (AKI) is the earliest and most described organ dysfunction associated with IAH. Moreover, AKI gravity seems to correlates with IAH severity. Physiopathological aspects explaining glomerular filtration rate (GFR) decrease with IAH are probably multifactorial and not completely understood. The role of renal venous congestion is essential to explain AKI in IAH. GFR decrease may reflect a "glomerular capillary shunt" due to a decrease of renal plasmatic flow. Monitoring IVP in daily practice in patients presenting risk factors of IAH would improve knowledge about this condition and the associated AKI.

AB - Mutations in GBA1 encountered in Gaucher disease are a leading risk factor for Parkinson disease and associated Lewy body disorders. Many GBA1 mutation carriers, especially those with severe or null GBA1 alleles, have earlier and more progressive parkinsonism. To model the effect of partial glucocerebrosidase deficiency on neurological progression in vivo, mice with a human A53T alpha synuclein (SNCAA53T) transgene were crossed with heterozygous null gba mice (gba+/-). Survival analysis of 84 mice showed that in gba+/-//SNCAA53T hemizygotes and homozygotes, the symptom onset was significantly earlier than in gba+/+//SNCAA53T mice (p-values 0.023-0.0030), with exacerbated disease progression (p-value <0.0001). Over-expression of SNCAA53T had no effect on glucocerebrosidase levels or activity. Immunoblotting demonstrated that gba haploinsufficiency did not lead to increased levels of either monomeric SNCA or insoluble high molecular weight SNCA in this model. Immunohistochemical analyses demonstrated that the abundance and distribution of SNCA pathology was also unaltered by gba haploinsufficiency. Thus, while the underlying mechanism is not clear, this model shows that gba deficiency impacts the age of onset and disease duration in aged SNCAA53T mice, providing a valuable resource to identify modifiers, pathways and possible moonlighting roles of glucocerebrosidase in Parkinson pathogenesis.

AB - INTRODUCTION AND OBJECTIVE: Fatigue and balance impairment leads to a loss of independence and are important to adequately manage. The objective of this study was to examine the effects of a resistance training program on dynamic balance and fatigue in patients with Parkinson's disease (PD). PATIENTS AND METHODS: Randomized controlled trial. Forty-six patients with PD were randomly allocated to an intervention group receiving a 8-week resistance training program focused on lower limbs or to a control group. Balance was assessed using the Mini-BESTest and fatigue was assessed by the Piper Fatigue Scale. RESULTS: Patients in the intervention group improved significantly (p<0.05) on dynamic balance (reactive postural control and total values) and perceived fatigue. CONCLUSIONS: An 8-week resistance training program was found to be effective at improving dynamic balance and fatigue in patients with PD.

AB - BACKGROUND AND OBJECTIVE: Our objective is to analyze the incidence of tuberculosis (TB) in our population and to compare the characteristics of patients with and without HIV infection. PATIENTS AND METHODS: Clinical epidemiological retrospective cohort study that included patients diagnosed with TB with and without HIV infection between 2005-2016 in the province of Guadalajara (Spain). Epidemiological, clinical, microbiological and therapeutic variables were assessed, including microbiological resistances. RESULTS: TB was diagnosed in 261 patients. There were 25 patients (9.6%) who had HIV infection. Patients with HIV infection were predominantly males, had higher incidence of hepatitis C virus, a higher percentage of extrapulmonary TB, a higher prevalence of resistance to isoniazid and rifampicin, a greater paradoxical response and a longer average hospital stay. On the other hand, they had a lower percentage of positive tuberculin skin test and positive sputum smear (microscopy). A significant percentage of TB patients had no serology for HIV. CONCLUSION: Patients with HIV infection show remarkable differences in epidemiological, clinical and resistance variables to antituberculosis drugs. A high percentage of patients with TB were not tested for HIV. PMID- 29173988 TI - Non compaction cardiomyopathy: Review of a controversial entity. AB - Non-compaction cardiomyopathy is a heterogeneous and complex entity concerning which there are still many doubts to be resolved. While the American Heart Association includes it among genetic cardiomyopathies, the European Society of Cardiology treats it as an unclassified cardiomyopathy. It may present in a sporadic or familial form, isolated or associated with other heart diseases, affecting only the left ventricle or both and can sometimes appear as a mixed phenotype in patients with other cardiomyopathies. Different forms of clinical presentation are also associated with its different morphological manifestations, and even non-compaction of the left ventricle may be triggered by other physiological or pathological processes. The purpose of this review is an update of this entity and its controversies. PMID- 29173989 TI - Use of Monte Carlo Techniques in Nuclear Medicine.

AB - The clinical features of parkinsonism in carbon monoxide (CO) intoxication have been associated with striatal-related neuronal networks. As parkinsonian and neuropsychiatric features are both related to presynaptic dopaminergic integrity, the aim of this study was to explore the clinical significance of 99mTcTRODAT-1 in grading neurobehavioral scores and parkinsonian severity in CO intoxication. We enrolled 64 patients with CO intoxication, including 29 with parkinsonism (parkinsonism[+] group) and 35 without (parkinsonism[-] group). All of the patients received 99mTcTRODAT-1 neuroimaging evaluations, comprehensive neurobehavioral tests and assessments of the severity of parkinsonism using Unified Parkinson's Disease Rating Scale (UPDRS)-part III motor score. Univariate and multivariate regression analyses were used to test the predictive factors and scores for a diagnosis of parkinsonism and its severity. The parkinsonism(+) group had significantly lower cognitive scores and higher neuropsychiatric total scores compared with the parkinsonism(-) group, both of which were independently related to the severity of parkinsonism. 99mTcTRODAT-1 regional caudate signals were correlated with tremors at rest, action or postural tremors of the hands, bradykinesia and hypokinesia, and visuospatial, verbal fluency, abstract thinking and digit backwards scores. Scores of the neurobehavioral tests and UPDRS items were highly correlated (p<0.01). Our results validated the initial hypothesis in that neurobehavioral deficits and parkinsonian symptoms were highly related. This association was independent of demographic factors and initial carboxyhemoglobin level. Within the presynaptic dopaminergic circuit, the clinical role of the caudate in mediating the clinical symptoms in CO intoxication may outweigh the putamen.

AB - The dermoscopic island is described as a well-defined area in a melanocytic lesion, with a different dermoscopic pattern from the rest of the lesion. It is predictive of melanoma, particularly when the pattern of the island is atypical. We present the reflectance confocal microscopy (RCM) findings in 3 lesions with dermoscopic islands: nevus-associated melanoma, melanocytic nevus, and in situ melanoma. The nevus-associated melanoma and in situ melanoma presented cellular atypia (atypical cells in isolation or forming nests) and architectural distortion on RCM. The nevus presented a dermoscopic island with a typical globular pattern with dense nests and no atypia on RCM. Dermoscopic island is mainly associated with in situ and nevus-associated melanomas. RCM offers good cellular resolution to the depth of the reticular dermis and is useful for diagnosing of melanomas presenting a dermoscopic island. PMID- 29173996 TI - Ulcerated Penile Lesion.

AB - The aim of this split-mouth, randomized, double-blind, controlled clinical trial was to evaluate the influence of different insertion torque values for dental implants on bone- and angiogenesis-related marker profiles. Eighteen edentulous patients received dental implants and fixed complete-arch mandibular prostheses. The implants (n=36) were assigned randomly to two groups: reduced torque (n=18), with insertion torque <30Ncm; and conventional torque (n=18), with insertion torque >=30Ncm. Levels of vascular endothelial growth factor (VEGF), placental growth factor, bone morphogenetic protein 9 (BMP-9), periostin, osteoprotegerin (OPG), and tartrate-resistant acid phosphatase (TRAP) in the peri-implant fluid were quantified at 7, 14, 30, and 120days after implant placement. Inter-group comparisons showed that VEGF and OPG levels were higher in the low-level torque group than in the conventional torque group on days 7 and 30, respectively (P<0.05). BMP-9 and periostin levels were higher in the conventional group than in the low-level torque group on day 120, and TRAP was up-regulated around implants inserted with conventional torque when compared to those inserted with lower-level torque at all time points evaluated (P<0.05). In conclusion, the use of different levels of torque for implantation of immediately loaded implants significantly influenced the levels of bone- and angiogenesis-related markers during early peri-implant repair.

PMID- 29174000 TI - Deficiency of leptin receptor in myeloid cells disrupts hypothalamic metabolic circuits and causes body weight increase. AB - OBJECTIVE: Leptin is a cytokine produced by adipose tissue that acts mainly on the hypothalamus to regulate appetite and energy homeostasis. Previous studies revealed that the leptin receptor is expressed not only in neurons, but also in glial cells. Microglia are resident immune cells in the brain that play an essential role in immune defense and neural network development. Previously we reported that microglial morphology and cytokine production are changed in the leptin receptor deficient db/db mouse, suggesting that leptin's central effects on metabolic control might involve signaling through microglia. In the current study, we aimed to uncover the role of leptin signaling in microglia in systemic metabolic control. METHODS: We generated a mouse model with leptin receptor deficiency, specifically in the myeloid cells, to determine the role of microglial leptin signaling in the development of metabolic disease and to investigate microglial functions. RESULTS: We discovered that these mice have increased body weight with hyperphagia. In the hypothalamus, pro-opiomelanocortin neuron numbers in the arcuate nucleus (ARC) and alpha-MSH projections from the ARC to the paraventricular nucleus (PVN) decreased, which was accompanied by the presence of less ramified microglia with impaired phagocytic capacity in the PVN. CONCLUSIONS: Myeloid cell leptin receptor deficient mice partially replicate the db/db phenotype. Leptin signaling in hypothalamic microglia is important for microglial function and a correct formation of the hypothalamic neuronal circuit regulating metabolism. PMID- 29174001 TI - Hot spots for the protein engineering of Baeyer-Villiger monooxygenases. AB - Baeyer-Villiger monooxygenases (BVMOs) are versatile biocatalysts for the conversion of ketones to lactones or esters while also being able to efficiently oxidize sulfides to sulfoxides. However, there are limitations for the application of BVMOs in synthesis. In this review we provide an overview of the protein engineering studies aiming at optimizing different properties of BVMOs. We describe hot spots in the active sites of certain BVMOs that have been successfully targeted for changing the substrate scope, as well as the possibility to influence this property by allosteric effects. The identified hot spots in the active sites for controlling enantio- and regioselectivity are shown to be transferable to other BVMOs and we describe concepts to influence heteroatom oxidation, improve protein stability and change the cofactor dependency of BVMOs. Summarizing all these different studies enabled the identification of BVMO- or property-dependent as well as universal hot spots.

AB - BACKGROUND: Diagnostic delay hinders management of pediatric arterial ischemic stroke. Quick brain MRI with diffusion-weighted imaging sequences may provide a rapid diagnosis without the ionizing radiation of a computed tomography (CT) scan. METHODS: This was a single center retrospective chart review of children one month to 18 years old with acute arterial ischemic stroke hospitalized between January 2010 and January 2017. We evaluated sensitivity and the time to diagnostic study based on the first imaging study (CT or quick brain MRI with diffusion-weighted imaging). RESULTS: Twenty-five patients were included. Eleven patients (44%) were initially assessed with CT, 10 (40%) with quick brain MRI with diffusion-weighted imaging, and four (16%) with a full MRI. Compared with children undergoing CT, children with quick brain MRI with diffusion-weighted imaging as first study were younger (5.8 versus 14.1 years, P < 0.001) and were more likely to be hospitalized at stroke onset (70% versus 18.2%, P = 0.03). Quick brain MRI with diffusion-weighted imaging was more sensitive for ischemia than CT (100% versus 27.3%). The median time from presentation to diagnostic imaging was 4.3 hours, with no differences between CT and quick brain MRI with diffusion-weighted imaging groups, although the quick brain MRI with diffusion weighted imaging group had a shorter median time from first imaging to diagnostic imaging (P = 0.002). There were no significant missed findings on quick brain MRI with diffusion-weighted imaging. CONCLUSIONS: Quick brain MRI with diffusion weighted imaging was more sensitive than CT for detecting ischemia and may be considered as the first study for some children presenting with suspected arterial ischemic stroke.

PMID- 29174007 TI - [Acute hemorrhagic edema of infancy associated with Coxsackie virus infection]. AB - Acute hemorrhagic edema of infancy is a rare but benign vasculitis occurring in infants aged from 4 to 24 months. Skin lesions can take various forms, including extensive hemorrhagic purpura, and can therefore be mistaken for purpura fulminans if associated with fever, which leads to initiating broad-spectrum antibiotic treatment. In the present case, we describe a 7-month-old boy with acute hemorrhagic edema of infancy and rapidly extensive purpura lesions that led to intravenous cefotaxime and amikacin treatment. Diagnosis was made on the next day by a dermatologist, based on the typical aspect of skin lesions, hemodynamic stability, and negative bacteriological samples. Coxsackie virus B5, a pathogenic enterovirus, was found by specific PCR in cerebrospinal fluid. The outcome was spontaneously favorable after discontinuation of antibiotics on day 2. We discuss the imputability of the enterovirus in triggering this case of acute hemorrhagic edema of infancy. PMID- 29174008 TI - [The use of the Debriefing Assessment for Simulation in Healthcare (DASH) in a simulation-based team learning program for newborn resuscitation in the delivery room]. AB - OBJECTIVE: To evaluate the contribution of the Debriefing Assessment for Simulation in Healthcare (DASH, Centre for Medical Simulation, Harvard) in a high fidelity simulation in situ program used for newborn resuscitation training. METHODS: The DASH was scored by trainees and instructors at the end of the session. The instructors' feedback and opinions were collected. RESULTS: The study included 16 training sessions (ten maternity units) with 156 trainees and ten instructors (45 DASH). The mean DASH score was rated at 6.6/7 by the learners and 5.4/7 by the instructors. For each element, the instructors scored the DASH lower than the learners (P<0.001). For each session, the instructors' DASH scores were lower than the learners' score (P<0.001). The instructors' DASH scores progressed during the first three sessions of the study. The instructors evaluated the DASH's usefulness at 3.6/7 in self-evaluation and at 6.3/7 if used collectively. CONCLUSION: The trainees evaluated the debriefing with high-level DASH scores, thus validating the educational aim of the program. In contrast, the instructors' DASH scores were lower and heterogeneous. Debriefing high-fidelity simulations remains a complex exercise. The use of the DASH can be a helpful measure for instructors in regard of their own practice. Its main advantage could be in providing a validated tool that will allow a "debriefing of debriefing". PMID- 29174009 TI - Guidelines for the clinical management and follow-up of infants with inconclusive cystic fibrosis diagnosis through newborn screening. AB - Neonatal screening for cystic fibrosis (CF) can detect infants with elevated immunoreactive trypsinogen (IRT) levels and inconclusive sweat tests and/or CFTR DNA results. These cases of uncertain diagnosis are defined by (1) either the presence of at most one CF-associated cystic fibrosis transmembrane conductance regulator (CFTR) mutation with sweat chloride values between 30 and 59mmol/L or (2) two CFTR mutations with at least one of unknown pathogenic potential and a sweat chloride concentration below 60mmol/L. This encompasses various clinical situations whose progression cannot be predicted. In these cases, a sweat chloride test has to be repeated at 12 months, and if possible at 6 and 24 months of life along with extended CFTR sequencing to detect rare mutations. When the diagnosis is not definite, CFTR functional explorations may provide a better understanding of CFTR dysfunction. The initial evaluation of these infants must be conducted in dedicated CF reference centers and should include bacteriological sputum analysis, chest radiology, and fecal elastase assay. The primary care physicians in charge of these patients should be familiar with the current management of CF and should work in collaboration with CF centers. A follow-up should be performed in a CF reference center at 3, 6, and 12 months of life and every year thereafter. Any symptom indicative of CF requires immediate reevaluation of the diagnosis. These guidelines were established by the "neonatal screening and difficult diagnoses" working group of the French CF society. Their objective is to standardize the management of infants with unclear diagnosis. PMID- 29174010 TI - Evaluation of photosynthetic activities in thylakoid membranes by means of Fourier transform infrared spectroscopy. AB - Light-induced Fourier transformed infrared (FTIR) difference spectroscopy is a powerful method to study the structures and reactions of redox cofactors involved in the photosynthetic electron transport chain. So far, most of the FTIR studies of the reactions of oxygenic photosynthesis have been performed using isolated photosystem I (PSI) and photosystem II (PSII) preparations, which, however, could be modified during isolation procedures. In this study, we developed a methodology to evaluate the photosynthetic activities of thylakoids using FTIR spectroscopy. FTIR difference spectra upon successive flashes using thylakoids from spinach exhibited signals typical of the S-state cycle at the Mn4CaO5 cluster and QB reactions in PSII with period-four and -two oscillations, respectively. Similar measurement in the presence of an artificial quinone as an exogenous electron acceptor showed features specific to the S-state cycle. Simulations of the oscillation patterns provided the quantum efficiencies of the S-state cycle and electron transfer in PSII. Moreover, FTIR measurement under continuous illumination on thylakoids in the presence of DCMU showed signals due to QA reduction and P700 oxidation simultaneously. From the relative amplitudes of marker bands of QA- and P700+, the molar ratio of photoactive PSII and PSI centers in thylakoids was estimated. FTIR analyses of the photo-reactions in thylakoids, which are more intact than isolated photosystems, will be useful in investigations of the photosynthetic mechanism especially by genetic modification of photosystem proteins. PMID- 29174011 TI - Apoprotein heterogeneity increases spectral disorder and a step-wise modification of the B850 fluorescence peak position. AB - It has already been established that the quaternary structure of the main light harvesting complex (LH2) from the photosynthetic bacterium Rhodopseudomonas palustris is a nonameric 'ring' of PucAB heterodimers and under low-light culturing conditions an increased diversity of PucB synthesis occurs. In this work, single molecule fluorescence emission studies show that different classes of LH2 'rings' are present in "low-light" adapted cells and that an unknown chaperon process creates multiple sub-types of 'rings' with more conformational sub-states and configurations. This increase in spectral disorder significantly augments the cross-section for photon absorption and subsequent energy flow to the reaction centre trap when photon availability is a limiting factor. This work highlights yet another variant used by phototrophs to gather energy for cellular development. PMID- 29174012 TI - Peripapillary and Macular Vessel Density in Patients with Primary Open-Angle Glaucoma and Unilateral Visual Field Loss. AB - PURPOSE: To characterize OCT angiography (OCT-A) vessel density of patients with primary open-angle glaucoma (POAG) with unilateral visual field (VF) loss. DESIGN: Cross-sectional study. PARTICIPANTS: A total of 33 patients with POAG with a VF defect in 1 eye (mean VF mean deviation [MD], -3.9+/-3.1 decibels [dB]) and normal VF in the other eye (mean VF MD, -0.2+/-0.9 dB) and 33 healthy eyes. METHODS: All subjects underwent OCT-A imaging, spectral-domain (SD)-OCT imaging, and VF testing. OCT-A retinal vascular measurements were summarized as whole image vessel density (wiVD), circumpapillary vessel density (cpVD), and parafoveal vessel density (pfVD). Inter-eye differences in vascular measures, as well as SD OCT retinal nerve fiber layer (RNFL), macular ganglion cell complex (mGCC) thickness, and rim area measurements in glaucoma and healthy eyes were compared. Areas under the receiver operating characteristic curves (AUROCs) were used to evaluate diagnostic accuracy for differentiating between unaffected eyes of patients with POAG and healthy eyes. MAIN OUTCOME MEASURES: Difference in OCT A vessel density and SD OCT structural parameters between unaffected eyes of patients with POAG with the fellow affected eyes and healthy controls. RESULTS: Mean wiVD in unaffected eyes of patients with POAG (52.0%) was higher than in their fellow affected eyes (48.8%) but lower than in healthy eyes (55.9%; P < 0.001). Mean circumpapillary RNFL (cpRNFL) thickness, mGCC thickness, and rim area measurement in unaffected eyes of patients with POAG (87.5 MUm, 87.7 MUm, and 1.0 mm2) were also higher than those measurements in their fellow eyes (76.5 MUm, 79.5 MUm, and 0.8 mm2; P < 0.001) and lower than in healthy eyes (98.0 MUm, 94.5 MUm, and 1.4 mm2; P < 0.001). The AUROCs for differentiating unaffected eyes of patients with POAG from healthy eyes were highest for wiVD (0.84), followed by mGCC (0.78), cpRNFL (0.77), and pfVD (0.69). CONCLUSIONS: OCT-A measures detect changes in retinal microvasculature before VF damage is detectable in patients with POAG, and these changes may reflect damage to tissues relevant to the pathophysiology of glaucoma. Longitudinal studies are needed to determine whether OCT-A measures can improve the detection or prediction of the onset and progression of glaucoma. PMID- 29174013 TI - The minor histocompatibility antigen 1 (HMHA1)/ArhGAP45 is a RacGAP and a novel regulator of endothelial integrity. AB - Endothelial cells line the vasculature and act as gatekeepers that control the passage of plasma, macromolecules and cells from the circulation to the interstitial space. Dysfunction of the endothelial barrier can lead to uncontrolled leak or edema. Vascular leakage is a hallmark of a range of diseases and despite its large impact no specialized therapies are available to prevent or reduce it. RhoGTPases are known key regulators of cellular behavior that are directly involved in the regulation of the endothelial barrier. We recently performed a comprehensive analysis of the effect of all RhoGTPases and their regulators on basal endothelial integrity. In addition to novel positive regulators of endothelial barrier function, we also identified novel negative regulators, of which the ArhGAP45 (also known as HMHA1) was the most significant. We now demonstrate that ArhGAP45 acts as a Rac-GAP (GTPase-Activating Protein) in endothelial cells, which explains its negative effect on endothelial barrier function. Silencing ArhGAP45 not only promotes basal endothelial barrier function, but also increases cellular surface area and induces sprout formation in a 3D-fibrin matrix. Our data further shows that loss of ArhGAP45 promotes migration and shear stress adaptation. In conclusion, we identify ArhGAP45 (HMHA1) as a novel regulator, which contributes to the fine-tuning of the regulation of basal endothelial integrity. PMID- 29174014 TI - Nanotechnology and primary hemostasis: Differential effects of nanoparticles on platelet responses. AB - Despite the numerous advantages offered by diverse platforms based on nanomedicine, several nanomaterials have shown significant cell toxicity that could induce chronic adverse effects on human health. Blood compatibility is one of the leading factors to consider for the design and development of nanosystems as therapeutics. Aforementioned is because systemic circulation is the gateway for most nano-drug therapeutic systems and its interactions with the blood components such as platelets could influence the maintenance of hemostasis and thrombus formation. Unfortunately, the thrombotoxicity of some nanomaterials regarding the activation/inhibition of platelets limits their biomedical applications. Additionally, the critical factors that drive those effects on platelet function are still not entirely elucidated. In this work, we describe the effect of different nanomaterials on the platelet function, its action mechanisms, and future potential as nanotherapeutics. PMID- 29174015 TI - Effect of statin therapy on the prevention of new-onset acute coronary syndrome in patients with rheumatoid arthritis. AB - BACKGROUND: The aim of this study is to investigate whether statin therapy can reduce new-onset acute coronary syndrome (ACS) in patients with rheumatoid arthritis (RA). METHODS: We used a database from the Registry for Catastrophic Illness from the National Health Research Institute (NHRI) in Taiwan. All RA patients aged 18 or older, diagnosed between 1995 and 2013, without previous cardiovascular events were included. We divided participants into quartiles according to the accumulated statin equivalent dosage and tertiles of period of days of statin treatment to examine the possible dose-response effect. To avoid confounding effects, a 1:4 propensity score matching and Cox's proportional hazard regression models were applied to estimate the hazard ratios for ACS events in patients with and without statin use. RESULTS: Total 49,227 patients were included and PS matching identified 5483 patients receiving statins and 21,932 who did not. RA patients treated with statins had lower incidence of first ACS event (IRR 0.779, 95% CI: 0.654-0.927, p=0.005) after PS matching. Statin therapy is associated with reduced risk of new ACS before PS matching (HR=0.847, 95% CI: 0.737-0.973, p=0.019) and the beneficial effect is correlated with accumulated dose and therapy duration (HRs from Q1 to Q4 are 1.215, 0.825, 0.716 and 0.611, p<0.001 for trend; HRs from T1 to T3 are 1.100, 0.841 and 0.611, p<0.001 for trend). These results remained robust after propensity matching. Comparison between 6 different statins, rosuvastatin seems to be associated with better outcome on ACS primary prevention after excluding participants taking more than one kind of statin. CONCLUSIONS: Our study demonstrated that statin therapy is associated with lower event rate of new-onset ACS in RA patients and the beneficial effect is dose-responsive. PMID- 29174016 TI - De novo mitral regurgitation as a cause of heart failure exacerbation in patients with hypertrophic cardiomyopathy. AB - AIMS: To determine the prevalence and mechanisms of de novo severe MR due to mitral valve structural abnormalities causing clinical deterioration in patients with HCM. METHODS AND RESULTS: This is an observational study based on HCM registry comprising consecutive HCM patients (n=397) who have been evaluated and followed in the Cardiomyopathy Clinic of Sheba Medical Center. Sixteen patients (4.0%), 8 males, mean age 65+/-14 years, developed acute clinical deterioration due to development of severe mitral regurgitation unrelated to mitral valve systolic anterior motion. Compared to the remaining HCM population, those patients were older at their initial diagnosis (51+/-20 vs. 38+/-18 years) and more often females. Most frequently (in 10 patients, 63%) mitral regurgitation resulted from a flail posterior leaflet, while 4 patients had severe prolapse and 2 had isolated mitral annular/leaflet calcifications. Fourteen underwent surgery; myxomatous changes were found in all excised valves (n=9). On age-adjusted univariate analysis, 3 clinical parameters remained significantly associated with the development of de novo MR, female gender, LVOT obstruction and significant MR at baseline. On multivariable analysis, only LVOT obstruction (HR=3.8) and MR at baseline evaluation (HR=8.2) predicted development of severe MR. CONCLUSIONS: De novo severe MR leading to acute heart failure was repeatedly observed in our HCM series. This etiology needs to be considered as a cause of acute clinical deterioration in these patients. PMID- 29174017 TI - Additive and independent prognostic role of abnormal right ventricle and pulmonary hypertension in mitral-tricuspid surgery. AB - OBJECTIVE: To evaluate the additive and independent prognostic value of abnormal right ventricle (aRV) and pulmonary hypertension (PH) in patients undergoing mitral-tricuspid surgery. METHODS: From January 2009 to December 2012, 541 patients underwent mitro-tricuspid surgery. The entire cohort was divided into 6 subgroups: 63 cases had normal RV and no PH (Group A), 180 normal RV but moderate PH (Group B), 101 normal RV but severe PH (Group C), 15 abnormal RV and no-PH (Group D), 86 abnormal RV and moderate PH (Group E) and 96 abnormal RV and severe PH (Group F). RESULTS: Forty-two (7.8%) patients died in hospital due to any cause: 1.6% in group A, 3.9% in group B, 8.9% in group C, 13.3% in group D, 9.3% in group E, 15.6% in group E, p = 0.005. Among 78 patients with no-PH, mortality was significantly higher in patients with aRV (1.6%vs 13.3%. p = 0.03). Among 344 patients with normal RV, mortality was significantly higher in patients with severe PH (1.6% vs 3.9% vs 8.9%. p = 0.03). Comparing the presence of both abnormal RV and severe PH with the remaining patients, mortality was significantly higher in the first group (15.6% 6.1%, p = 0.004). Multivariable analysis confirmed either the independent or the additive role of RV and PH. CONCLUSIONS: In patients undergoing mitral-tricuspid valve surgery, the presence of either RV dysfunction/dilatation or severe pulmonary hypertension, might play an independent prognostic role for mortality. The worst scenario is surely the contemporary presence of both conditions. PMID- 29174018 TI - Interobserver and intraobserver reliability of radiographic classification of acromioclavicular joint dislocations. AB - HYPOTHESIS AND BACKGROUND: The classification and treatment of acromioclavicular (AC) joint dislocations remain controversial. The purpose of this study was to determine the interobserver and intraobserver reliability of the Rockwood classification system. We hypothesized poor interobserver and intraobserver reliability, limiting the role of the Rockwood classification system in determining severity of AC joint dislocations and accurately guiding treatment decisions. METHODS: We identified 200 patients with AC joint injuries using the International Classification of Diseases, Ninth Revision code 831.04. Fifty patients met inclusion criteria. Deidentified radiographs were compiled and presented to 6 fellowship-trained upper extremity orthopedic surgeons. The surgeons classified each patient into 1 of the 6 classification types described by Rockwood. A second review was performed several months later by 2 surgeons. A kappa value was calculated to determine the interobserver and intraobserver reliability. RESULTS: The interobserver and intraobserver kappa values were fair (kappa = 0.278) and moderate (kappa = 0.468), respectively. Interobserver results showed that 4 of the 50 radiographic images had a unanimous classification. Intraobserver results for the 2 surgeons showed that 18 of the 50 images were rated the same on second review by the first surgeon and 38 of the 50 images were rated the same on second review by the second surgeon. CONCLUSION: We found that the Rockwood classification system has limited interobserver and intraobserver reliability. We believe that unreliable classification may account for some of the inconsistent treatment outcomes among patients with similarly classified injuries. We suggest that a better classification system is needed to use radiographic imaging for diagnosis and treatment of AC joint dislocations. PMID- 29174019 TI - Collar occupancy: A new quantitative imaging tool for morphometric analysis of oligodendrocytes. AB - BACKGROUND: Oligodendrocytes (OL) are the myelinating cells of the central nervous system. OL differentiation from oligodendrocyte progenitor cells (OPC) is accompanied by characteristic stereotypical morphological changes. Quantitative imaging of those morphological alterations during OPC differentiation is commonly used for characterization of new molecules in cell differentiation and myelination and screening of new pro-myelinating drugs. Current available imaging analysis methods imply a non-automated morphology assessment, which is time consuming and prone to user subjective evaluation. NEW METHOD: Here, we describe an automated high-throughput quantitative image analysis method entitled collar occupancy that allows morphometric ranking of different stages of in vitro OL differentiation in a high-content analysis format. Collar occupancy is based on the determination of the percentage of area occupied by OPC/OL cytoplasmic protrusions within a defined region that contains the protrusion network, the collar. RESULTS: We observed that more differentiated cells have higher collar occupancy and, therefore, this parameter correlates with the degree of OL differentiation. COMPARISON WITH EXISTING METHODS: In comparison with the method of manual categorization, we found the collar occupancy to be more robust and unbiased. Moreover, when coupled with myelin basic protein (MBP) staining to quantify the percentage of myelinating cells, we were able to evaluate the role of new molecules in OL differentiation and myelination, such as Dusp19 and Kank2. CONCLUSIONS: Altogether, we have successfully developed an automated and quantitative method to morphologically characterize OL differentiation in vitro that can be used in multiple studies of OL biology. PMID- 29174020 TI - Looking for Alzheimer's Disease morphometric signatures using machine learning techniques. AB - BACKGROUND: We present our results in the International challenge for automated prediction of MCI from MRI data. We evaluate the performance of MRI-based neuromorphometrics features (nMF) in the classification of Healthy Controls (HC), Mild Cognitive Impairment (MCI), converters MCI (cMCI) and Alzheimer's Disease (AD) patients. NEW METHODS: We propose to segregate participants in three groups according to Mini Mental State Examination score (MMSEs), searching for the main nMF in each group. Then we use them to develop a Multi Classifier System (MCS). We compare the MCS against a single classifier scheme using both MMSEs+nMF and nMF only. We repeat this comparison using three state-of-the-art classification algorithms. RESULTS: The MCS showed the best performance on both Accuracy and Area Under the Receiver Operating Curve (AUC) in comparison with single classifiers. The multiclass AUC for the MCS classification on Test Dataset were 0.83 for HC, 0.76 for cMCI, 0.65 for MCI and 0.95 for AD. Furthermore, MCS's optimum accuracy on Neurodegenerative Disease (ND) detection (AD+cMCI vs MCI+HC) was 81.0% (AUC=0.88), while the single classifiers got 71.3% (AUC=0.86) and 63.1% (AUC=0.79) for MMSEs+nMF and only nMF respectively. COMPARISON WITH EXISTING METHOD: The proposed MCS showed a better performance than using all nMF into a single state-of-the-art classifier. CONCLUSIONS: These findings suggest that using cognitive scoring, e.g. MMSEs, in the design of a Multi Classifier System improves performance by allowing a better selection of MRI-based features. PMID- 29174021 TI - Sudden cardiac death preceded by ST segment elevations during ECG patch monitoring. AB - A 58-year-old male underwent ambulatory ECG monitoring with continuous patch monitoring (Zio XT Patch) for the complaint of episodic dyspnea. In the period of monitoring the patient suffered sudden cardiac death (SCD) with continuous ECG recording showing pronounced ST segment elevations followed by bradycardia and death. This report highlights the growing potential of continuous ST segment monitoring, and features the infrequent entity of ischemic electromechanical dissociation with bradyarrhythmia as a cause of SCD. PMID- 29174022 TI - Patients with left bundle branch block and left axis deviation show a specific left ventricular asynchrony pattern: Implications for left ventricular lead placement during CRT implantation. AB - BACKGROUND: Left bundle branch block (LBBB) and left axis deviation (LAD) patients may have poor response to resynchronization therapy (CRT). We sought to assess if LBBB and LAD patients show a specific pattern of mechanical asynchrony. METHODS: CRT candidates with non-ischemic cardiomyopathy and LBBB were categorized as having normal QRS axis (within -30 degrees and +90 degrees ) or LAD (within -30 degrees and -90 degrees ). Patients underwent tissue Doppler imaging (TDI) to measure time interval between onset of QRS complex and peak systolic velocity in ejection period (Q-peak) at basal segments of septal, inferior, lateral and anterior walls, as expression of local timing of mechanical activation. RESULTS: Thirty patients (mean age 70.6years; 19 males) were included. Mean left ventricular ejection fraction was 0.28+/-0.06. Mean QRS duration was 172.5+/-13.9ms. Fifteen patients showed LBBB with LAD (QRS duration 173+/-14; EF 0.27+/-0.06). The other 15 patients had LBBB with a normal QRS axis (QRS duration 172+/-14; EF 0.29+/-0.05). Among patients with LAD, Q-peak interval was significantly longer at the anterior wall in comparison to each other walls (septal 201+/-46ms, inferior 242+/-58ms, lateral 267+/-45ms, anterior 302+/-50ms; p<0.0001). Conversely, in patients without LAD Q-peak interval was longer at lateral wall, when compared to each other (septal 228+/-65ms, inferior 250+/ 64ms, lateral 328+/-98ms, anterior 291+/-86ms; p<0.0001). CONCLUSIONS: Patients with heart failure, presenting LBBB and LAD, show a specific pattern of ventricular asynchrony, with latest activation at anterior wall. This finding could affect target vessel selection during CRT procedures in these patients. PMID- 29174023 TI - Antibiotic treatment of asymptomatic bacteriuria prior to hip and knee arthroplasty; a systematic review of the literature. AB - BACKGROUND: There is significant debate as to whether routine antibiotic treatment of asymptomatic bacteriuria (ASB) in arthroplasty patients reduces the risk of subsequent PJI. No previous systematic reviews have been undertaken on this subject. The aim of this systematic review was to investigate whether antibiotic treatment of asymptomatic bacteriuria in arthroplasty patients reduces the risk of prosthetic joint infection and to investigate whether the organisms cultured in peri-operative urine samples are the same as those responsible for subsequent prosthetic joint infections. METHODS: Medline and SCOPUS databases were searched using a systematic search strategy. Inclusion Criteria were that the paper must present data detailing infection rates in patients with asymptomatic bacteriuria versus those without and must provide information on infection rates for ASB patients treated with antibiotics versus those not treated. Non-English Language papers and Conference Abstracts in which a full manuscript was not published were excluded. Two hundred and five papers were returned - three papers were included in the review, comprising 3267 patients. RESULTS: Only 3 studies met the inclusion criteria. The published literature does not support the routine antibiotic treatment of asymptomatic bacteriuria in arthroplasty patients. The organisms responsible for peri-prosthetic joint infection in patients with pre-operative asymptomatic bacteriuria are different from that cultured in their urine during the pre-operative period. This means that, although biologically possible, a direct causal relationship appears extremely unlikely. CONCLUSIONS: The evidence base supporting antibiotic treatment of asymptomatic bacteriuria prior to arthroplasty surgery is weak. Given the lack of evidence to support a direct causal relationship, routine antibiotic treatment of ASB in arthroplasty patients is not justified. PMID- 29174024 TI - In vitro antitumor effect of a lignan isolated from Combretum fruticosum, trachelogenin, in HCT-116 human colon cancer cells. AB - The use of natural products in therapeutics has been growing over the years. Lignans are compounds with large pharmaceutical use, which has aroused interest in the search for new drugs to treat diseases. The present study evaluated the cytotoxicity of (-)-trachelogenin, a dibenzylbutyrolactone type lignan isolated from Combretum fruticosum, against several tumor and non-tumor cell lines using the MTT assay and its possible mechanism of action. (-)-Trachelogenin showed IC50 values ranging of 0.8-32.4MUM in SF-295 and HL-60 cell lines, respectively and IC50 values >64MUM in non-tumor cell lines. (-)-trachelogenin persistently induced autophagic cell death, with cytoplasmic vacuolization and formation of autophagosomes mediated by increasing LC3 activation and altering the expression levels of Beclin-1. PMID- 29174025 TI - A systematic review of the effect of dietary saturated and polyunsaturated fat on heart disease. AB - AIMS: Over the last 7 years there has been intense debate about the advice to reduce saturated fat and increase polyunsaturated fat to reduce CVD risk. The aim of this review was to examine systematic reviews and meta-analyses since 2010 on this topic plus additional cohort studies and interventions not included in these reviews. DATA SYNTHESIS: High saturated and trans fat intake (which elevates LDL like saturated fat) in the Nurses and Health Professional Follow-Up Studies combined is associated with an 8-13% higher mortality and replacement of saturated fat with any carbohydrate, PUFA and MUFA is associated with lower mortality with PUFA being more effective than MUFA (19% reduction versus 11%). With CVD mortality only PUFA and fish oil replacement of saturated fat lowers risk with a 28% reduction in CVD mortality per 5% of energy. Replacing saturated fat with PUFA or MUFA is equally effective at reducing CHD events and replacement with whole grains will lower events while replacement with sugar and starch increases events. Replacement of saturated fat with carbohydrate has no effect on CHD events or death. Only PUFA replacement of saturated fat lowers CHD events and CVD and total mortality. Replacing saturated fat with linoleic acid appears to be beneficial based on the Hooper Cochrane meta-analysis of interventions although other analyses with fewer studies have shown no effect. CONCLUSIONS: Reducing saturated fat and replacing it with carbohydrate will not lower CHD events or CVD mortality although it will reduce total mortality. Replacing saturated fat with PUFA, MUFA or high-quality carbohydrate will lower CHD events. PMID- 29174026 TI - Adverse events with sodium-glucose co-transporter-2 inhibitors: A global analysis of international spontaneous reporting systems. AB - BACKGROUND AND AIMS: We assessed post-marketing safety of sodium-glucose co transporter-2 inhibitors (SGLT2-Is) by analyzing adverse events (AEs) reported in international pharmacovigilance databases. METHODS AND RESULTS: Eudravigilance, WHO-Vigibase (as of Feb 25, 2017) and the FDA Adverse Event Reporting System (FAERS, from 2004 to 2016 second quarter) were queried to extract AEs recording SGLT2-Is as suspect. Disproportionality analyses (case/non-case method) were performed in FAERS by calculating the reporting odds ratios (RORs) from System Organ Classes (SOCs) to Preferred Terms (PTs) (precise clinical entities). Potential signals were defined by statistically-significant ROR (lower limit of the 95% confidence interval - LL95%CI - >1) undetected by literature analysis (as of December 2016). SGLT2-Is were recorded in 7972, 19,775, 11,137 reports (Eudravigilance, WHO-Vigibase and FAERS, respectively); in FAERS, statistically significant ROR emerged for the following SOCs: "infections and infestations" (N = 2162; LL95%CI = 3.25), "metabolism and nutrition disorders" (2278; 1.36), "renal and urinary disorders" (1665; 2.31), "reproductive system and breast disorders" (471; 4.85), "skin and subcutaneous tissue disorders" (1136; 1.52). Skin toxicity emerged as potential signal (e.g., rash, photosensitivity, urticaria as PTs), both for SGLT2-Is as a class and as individual drugs. Severe adverse skin events (81 reports, 7% of the skin cases) mainly occurred in females aged 18-65 using SGLT2-Is as single antidiabetic regimen. CONCLUSION: Among antidiabetics, SGLT2-Is are associated with higher reporting of infections, metabolism, renal and reproductive AEs, corroborating clinical trial evidence. Their large reporting patterns and the unexpected signal of skin toxicity justify active vigilance by clinicians and "real-time" monitoring by pharmacovigilance experts. PMID- 29174027 TI - Association of serum fibroblast growth factor 19 levels with visceral fat accumulation is independent of glucose tolerance status. AB - BACKGROUND AND AIMS: Recent studies suggested that circulating fibroblast growth factor (FGF) 19 levels might be associated with the fat content and distribution, and varied with different glucose tolerance status. This study aimed to investigate the association of serum FGF19 levels with obesity and visceral fat accumulation in a Chinese population with differing glucose tolerance status. METHODS AND RESULTS: The 2383 participants were divided into subgroups of glucose tolerance status: normal glucose tolerance (NGT, n = 1754), impaired glucose regulation (IGR, n = 499), and newly diagnosed diabetes mellitus (DM, n = 130). They were further stratified into quartiles of serum FGF19 levels (Q1-Q4). Visceral fat area (VFA) and subcutaneous fat area were measured using magnetic resonance imaging. FGF19 were detected via quantitative sandwich enzyme-linked immunosorbent assay. Serum FGF19 levels showed a downtrend across the NGT, IGR, and DM groups (P for trend = 0.016). VFA was an independent and negative factor of serum FGF19 levels (standardized beta = -0.108, P = 0.001). After adjustment for glucose tolerance status, VFA differed significantly among FGF19 quartiles (P < 0.001), showing a downtrend from Q1-Q4. The associations of serum FGF19 levels and glucose tolerance status with VFA were independent of each other. After adjustment for insulin resistance and secretory function separately, VFA still decreased significantly from Q1-Q4 (all P < 0.001). CONCLUSION: Serum FGF19 levels were related to visceral fat accumulation. Independent of glucose tolerance status, serum FGF19 levels were inversely associated with VFA. PMID- 29174029 TI - Interrelationship of the rs7903146 TCF7L2 gene variant with measures of glucose metabolism and adiposity: The NEO study. AB - BACKGROUND AND AIMS: We investigated the interrelationship of rs7903146-T in TCF7L2 with measures of glucose metabolism and measures of adiposity. METHODS AND RESULTS: This cross-sectional analysis was conducted in 5744 middle-aged participants (mean (standard deviation [SD]) age is 55.9 (6.0) years) from the Netherlands Epidemiology of Obesity (NEO) Study. Associations between rs7903146-T and Type 2 diabetes mellitus (T2D) were assessed with logistic regression. Additive (per-allele) associations with measures of glucose metabolism (e.g., fasting insulin) and adiposity (e.g., body mass index [BMI]) were examined with multivariable linear regression. In the total study population, rs7903146-T was associated with a higher risk of T2D (additive odds ratio: 1.42; 95% confidence interval: 1.17; 1.72), and specifically with T2D treated with insulin analogs (2.31 [1.19; 4.46]). After exclusion of participants treated with glucose lowering medication, rs7903146-T was associated with lower mean insulin concentration (additive mean difference: -0.07 SD [-0.14; 0.00]), but not with higher mean glucose concentration (0.03 SD [-0.01; 0.07]). Furthermore, rs7903146 T was associated with, among other measures of adiposity, a lower mean BMI (-0.04 SD [-0.09; -0.00]), and a lower mean total body fat (-0.04 SD [-0.08; -0.00]). The association between rs7903146-T and T2D increased after adjustment for BMI (odds ratio: 1.51 [1.24; 1.86]); the association between rs7903146-T and fasting insulin diminished after adjustment (-0.05 SD [-0.11; 0.02]). CONCLUSION: rs7903146-T is associated with a decreased insulin concentration and increased risk of T2D with opposing effects of adjustment for adiposity.

AB - BACKGROUND: Interest in vegetarian diets is growing in Italy and elsewhere, as government agencies and health/nutrition organizations are emphasizing that regular consumption of plant foods may provide health benefits and help prevent certain diseases. METHODS AND RESULTS: We conducted a Pubmed search, up to September, 2015, for studies on key nutrients (proteins, vitamin B12, iron, zinc, calcium, vitamin D, and n-3 fatty acids) in vegetarian diets. From 295 eligible publications the following emerged: Vegetarians should be encouraged to supplement their diets with a reliable source of vitamin B12 (vitamin-fortified foods or supplements). Since the plant protein digestibility is lower than that of animal proteins it may be appropriate for vegetarians to consume more proteins than recommended for the general population. Vegetarians should also be encouraged to habitually consume good sources of calcium, iron and zinc - particularly vegetables that are low in oxalate and phytate (e.g. Brassicaceae), nuts and seeds, and calcium-rich mineral water. Calcium, iron, and zinc bioavailability can be improved by soaking, germination, and sour-dough leavening that lower the phytate content of pulses and cereals. Vegetarians can ensure good n-3 fatty acid status by habitually consuming good sources of a-linolenic acid (walnuts, flaxseeds, chia seeds, and their oils) and limiting linoleic acid intake (corn and sunflower oils). CONCLUSIONS: Well-planned vegetarian diets that include a wide variety of plant foods, and a reliable source of vitamin B12, provide adequate nutrient intake. Government agencies and health/nutrition organizations should provide more educational resources to help Italians consume nutritionally adequate vegetarian diets. PMID- 29174031 TI - Acute renal failure with sodium-glucose-cotransporter-2 inhibitors: Analysis of the FDA adverse event report system database. AB - BACKGROUND AND AIMS: Sodium-glucose-cotransporter-2 (SGLT2) inhibitors have recently been approved for the treatment of type II diabetes mellitus (T2DM). It has been proposed that these agents could induce acute renal failure (ARF) under certain conditions. This study aimed to evaluate the association between SGLT2 inhibitors and ARF in the FDA adverse event report system (FAERS) database. METHODS AND RESULTS: We analyzed adverse event cases submitted to FAERS between January 2013 and September 2016. ARF cases were identified using a structured medical query. Medications were identified using both brand and generic names. During the period evaluated, 18,915 reports (out of a total of 3,832,015 registered in FAERS) involved the use of SGLT2-inhibitors. SGLT2-inhibitors were reportedly associated with ARF in 1224 of these cases (6.4%), and were defined as the "primary" or "secondary" cause of the adverse event in 96.8% of these cases. The proportion of reports with ARF among reports with SGLT2 inhibitor was almost three-fold higher compared to reports without these drugs (ROR 2.88, 95% CI 2.71 3.05, p < 0.001). The proportion of ARF reports among cases with SGLT2-inhibitors was significantly greater than the proportion of ARF among cases with T2DM without SGLT2-inhibitors (ROR 1.68, 95% CI 1.57-1.8, p < 0.001). Among the SGLT2 inhibitors, canagliflozin was associated with a higher proportion of reports of renal failure (7.3%), compared to empagliflozin and dapagliflozin (4.7% and 4.8% respectively, p < 0.001). CONCLUSION: SGLT2-inhibitors are associated with an increase in the proportion of reports of ARF compared to other medications. SGLT2 inhibitor agents may differ from one another in their respective risk for ARF. PMID- 29174032 TI - Associations between neck symptoms and LDL cholesterol in a cross-sectional population-based study. AB - BACKGROUND: Studies have reported associations between neck pain and degenerative changes in the cervical spine in women, and between neck pain and obesity or metabolic syndrome. The present study investigated associations between neck pain or stiffness and lipid profiles in subjects recruited from the general population of a Japanese community. METHODS: The 1122 volunteers who participated in this study included 426 men (age 52.6 +/- 15.5 years; body mass index 23.6 +/- 3.2) and 696 women (age 55.3 +/- 15.3 years; body mass index 22.2 +/- 3.4). Each subject filled out a questionnaire about any neck pain or neck-shoulder stiffness experienced in the previous 3 months. We recorded the following laboratory results related to metabolic factors, including lipid profiles: total cholesterol, LDL and HDL cholesterol, triglycerides, free fatty acids, glucose, and hemoglobin A1c. We conducted logistic and linear regression analyses using the prevalence of neck pain or neck-shoulder stiffness as the dependent variable and age, sex, body mass index, and laboratory data as independent variables. RESULTS: There was no significant difference in the prevalence of neck pain between men (20.5%) and women (21.5%). However, the prevalence of neck and shoulder stiffness was significantly higher in women (60.3%) than in men (38.0%; P < 0.05). Logistic and linear regression analyses showed a significant negative correlation between the prevalence of neck pain and LDL cholesterol (odds ratio [OR], 0.958; 95% CI, 0.921-0.997), and between the prevalence of neck-shoulder stiffness and age (OR, 1.025; 95% CI, 1.013-1.038) and gender (OR, 0.362; 95% CI, 0.25-0.494). CONCLUSION: LDL cholesterol was correlated with neck pain in this cross-sectional population-based study. PMID- 29174033 TI - Anti-cancer and anti-angiogenic effects of partially purified lectin from Praecitrullus fistulosus fruit on in vitro and in vivo model. AB - Praecitrullus fistulosus, belonging to the family of Cucurbitaceae is a tropical vegetable and medicinal plant, grown and consumed extensively in subtropical countries, including the subcontinent India. However, there are limited reports on the medicinal properties of the plant and need to be explored. The lectin identified from the fruit sap of Praecitrullus fistulosus, named as PfLP, possesses potent agglutinating activity against trypsinized rabbit erythrocytes and exhibited its functional role against tumor progression, on in vitro &in vivo models. Experimental results revealed that PfLP shows a promising cytotoxic effect against multiple cancer cell lines. Further, we examined the in vivo anticancer and anti-angiogenic properties of PfLP against EAC bearing mice. PfLP treatment resulted in tumor growth inhibition and increased the life-span of the EAC bearing mice, without showing any detectable side effects, as revealed by histological parameters. Further, a significant decrease in the ascites VEGF secretion level was parallel with a drastic reduction in tumoral neovasculature as evidence for angiogenic parameters. Gelatin zymogram study reveals that PfLP inhibits metalloproteinases (MMP-2 & MMP-9) activity in order to execute its anti angiogenic effect. PfLP has also inducing apoptosis, in cancer cells was revealed by DNA fragmentation assay followed by Giemsa and AO/EBr staining method, showed the apoptotic bodies and condensed nuclei compared to control cells. More interestingly, PfLP did not exhibit any adverse side effects or secondary complications in normal mice. These results clearly exhibit the potential role of PfLP in regressing the tumor progression by targeting angiogenesis and inducing cell death in mouse transplantable tumor. PMID- 29174028 TI - Inflammation in metabolically healthy and metabolically abnormal adolescents: The HELENA study. AB - BACKGROUND AND AIMS: Inflammation may influence the cardio-metabolic profile which relates with the risk of chronic diseases. This study aimed to assess the inflammatory status by metabolic health (MH)/body mass index (BMI) category and to assess how inflammatory markers can predict the cardio-metabolic profile in European adolescents, considering BMI. METHODS AND RESULTS: A total of 659 adolescents (295 boys) from a cross-sectional European study were included. Adolescents were classified by metabolic health based on age- and sex-specific cut-off points for glucose, blood pressure, triglycerides, high density cholesterol and BMI. C-reactive protein (CRP), tumor necrosis factor alpha (TNF alpha), interleukin (IL-6), complement factors (C3, C4) and cell adhesion molecules were assessed. RESULTS: Metabolically abnormal (MA) adolescents had higher values of C3 (p < 0.001) and C4 (p = 0.032) compared to those metabolically healthy (MHy). C3 concentrations significantly increased with the deterioration of the metabolic health and BMI (p < 0.001). Adolescents with higher values of CRP had higher probability of being in the overweight/obese-MH group than those allocated in other categories. Finally, high C3 and C4 concentrations increased the probability of having an unfavorable metabolic/BMI status. CONCLUSIONS: Metabolic/BMI status and inflammatory biomarkers are associated, being the CRP, C3 and C4 the most related inflammatory markers with this condition. C3 and C4 were associated with the cardio-metabolic health consistently. PMID- 29174034 TI - Panax notoginseng saponins reduce high-risk factors for thrombosis through peroxisome proliferator-activated receptor -gamma pathway. AB - The classic Virchow theory suggests that blood stasis, hypercoagulability and endothelial dysfunction are three major factors that cause venous thrombosis (VT). It is a complicated biological process involved multi-factors. Platelet plays a central role and participates in multiple links of this process. Panax notoginseng saponins (PNS), the principal constituents derived from panax notoginseng, has been widely described for its anti-platelet activity. However, its potential mechanism against platelet aggregation has not been clarified. In this present study, we evaluated the anti-platelet effects of PNS on thrombin induced platelet activation and its possible molecular mechanism of action, and further explored the therapeutic action of PNS on thrombin induced hypercoagulability in rat. Our results showed that PNS treatment inhibited platelet aggregation induced by thrombin, which was accompanied with over expression of Peroxisome proliferator-activated receptor gamma (PPAR-gamma) protein, mRNA and upregulation of phosphatidylinositol 3 kinase (PI3K)/ protein kinase B (Akt)/ endothelial nitric oxide synthase (eNOS) pathway in platelet, and this effect could be reversed by PPAR-gamma inhibitor T0070907. In vivo, PNS significantly reversed thrombin-induced hypercoagulable state in rat which was accompanied by PPAR-gamma protein and mRNA upregulation in rat lung. In conclusion, these data suggested that PNS could suppress thrombin-induced platelet aggregation in vitro and effectively improve hypercoagulable state in vivo and PNS-induced activation of PPAR-gamma and its downstream PI3K/Akt/eNOS pathway played the central role. PMID- 29174035 TI - Effects of standard ethanolic extract from Erythrina velutina in acute cerebral ischemia in mice. AB - The objective of this study was to verify a possible neuroprotective effect of the ethanolic extract of Erythrina velutina (EEEV). Male Swiss mice were submitted to transient cerebral ischemia by occlusion of both carotid arteries for 30 min and treated for 5 days with EEEV (200 or 400 mg/kg) or Memantine (MEM) 10 mg/kg, with initiation of treatment 2 or 24 h after Ischemia. On the 6th day after the induction of ischemia, the animals were submitted to evaluation of locomotor activity and memory and then sacrificed. The brains were dissected for the removal of the prefrontal cortex (PFC), hippocampus (HC) and striatum (ST) for determination of amino acid concentrations. In the step down and Y-maze tests, ischemia caused damage to the animals and treatment with EEEV or MEM reversed this effect. The animals submitted to ischemia also showed memory deficit in the object recognition test, an effect that was reverted by EEEV400 and MEM10. Amino acid dosage showed an increase in excitatory amino acid concentrations in the PFC of the ischemic animals and this effect was reversed by the treatment with EEEV400/24H. Regarding the inhibitory amino acids, ischemia caused an increase of taurine in the PFC while treatment with MEM10/24H or EEEV400/24H reversed this effect. In HC, an increase in excitatory amino acids was also observed in ischemiated animals having treatment with EEEV200/2H or EEEV400/24H reversed this effect. Similar effect was also observed in the same area in relation to the inhibitory amino acids with treatment with MEM10/24H or EEEV400/24H. In the ST, ischemia was also able to cause an increase in excitatory amino acids that was reversed more efficiently by the treatments with MEM10/24H and EEEV200. Also in this area, an increase of taurine and GABA was observed and only the treatment with EEEV200/2H showed a reversion of this effect. In view of these findings, EEEV presents a neuroprotective effect possibly due to its action on amino acid concentrations, and is therefore a potential therapeutic tool in reducing the damage caused by ischemia. PMID- 29174036 TI - Increase in renal erythropoietin receptors in diabetic rats is mainly mediated by hyperglycemia associated with the STAT3/GATA-1 signaling pathway. AB - Erythropoietin (EPO) produces cytoprotection in many tissues by activating the EPO receptor (EPOR); these effects include anti-oxidative stress and the inhibition of apoptosis in renal tubular cells. Moreover, EPO is clinically used in diabetic patients who suffer from chronic renal disease. However, the effect of hyperglycemia on renal EPOR expression remains unknown. Therefore, we determined the changes in renal EPOR expression in diabetic rats and investigated the role of potential factors using cultured cells. Streptozotocin-induced hyperglycemic rats (STZ rats) treated with insulin or phloridzin to correct hyperglycemia were used to investigate treated with insulin or phloridzin to correct hyperglycemia were used to investigate the EPOR changes. Potential factors, including the transducer and activator of transcription 3 (STAT3) and GATA binding protein 1 (GATA1), were identified in cultured NRK-49F cells after incubation with high glucose (HG) levels to mimic diabetic animals. Renal EPOR expression was reduced by insulin and phloridzin in STZ rats, and hyperglycemia recovered. An increase in EPORs was also reproduced in hyperglycemia-exposed NRK 49F cells and HK-2 cells, which showed a higher expression of STAT3 or GATA1. Furthermore, the application of siRNA specific to STAT3 or GATA1 attenuated the higher expression of EPORs in HG-incubated NRK-49F cells. Moreover, stattic administered at a dose that was sufficient to inhibit STAT3 restored the level of renal EPORs in diabetic rats. Taken together, the expression of renal EPORs is increased by hyperglycemia via the STAT3/GATA1 pathway and has been characterized in both diabetic rats and cultured cells. PMID- 29174037 TI - Cellular senescence and liver disease: Mechanisms and therapeutic strategies. AB - Cellular senescence is a fundamental cell fate caused by several cellular injuries which results in irreversible cell cycle arrest yet remaining metabolically active across all species. Cellular senescence not only can prevent tumor occurrence by inhibiting the proliferation of injured cells, but also can affect the surrounding cells through the senescence-associated secretory phenotype (SASP). Attractively, accumulating evidence shows that cellular senescence is closely related to various liver diseases. Therapeutic opportunities based on targeting senescent cells and the SASP are considered to be potential strategy for liver diseases. However, although research on cell senescence has attracted widespread attention, the overview on detailed mechanism and biological function of cell senescence in liver disease is still largely unknown. The present review summarizes the specific role of cell senescence in various liver diseases, and updates the molecular mechanisms underlying cell senescence. Moreover, the review also explores new strategies for prevention and treatment of liver disease through promoting senescence or counteracting excessive pathological senescence. PMID- 29174038 TI - Lycopene amends LPS induced oxidative stress and hypertriglyceridemia via modulating PCSK-9 expression and Apo-CIII mediated lipoprotein lipase activity. AB - This study was undertaken to uncover the regulatory role of lycopene in targeting lipopolysaccharide (LPS) induced oxidative stress and inflammatory cascades and subsequent regulation of proprotein convertase subtilisin/kexin type-9 (PCSK-9) expression via sterol regulatory element binding protein-2 (SREBP-2) and hepatocyte nuclear factor-1alpha (HNF-1alpha). Further, protein-protein interaction (PPI) studies for Lycopene-Apo-CIII complex against lipoprotein lipase (LPL) were also performed to assess its regulatory role behind the enhanced circulatory TG/TRLs clearance. Lycopene treatment down-regulated hepatocyte PCSK-9 expression via down-regulation of HNF-1alpha, whereas, LDL receptor (LDL-R) was up-regulated by subsequent up-regulation of SREBP-2. PPI studies showed that lycopene diminishes the affinity of Apo-CIII to complex with LPL (DeltaG: -917.1 Kcal/mol) resulting in increased LPL functionality and TRLs clearance. Moreover, lycopene also ameliorated LPS stimulated oxidative-stress via enhanced total antioxidant and HDL associated PON-1 activity in addition to down-regulate the expression and plasma level of inflammatory mediators. Based on above findings, we concluded that lycopene exhibits dual role in targeting LPS induced oxidative stress and hypertriglyceridemia via down-regulation of PCSK-9, making greater no. of surface LDL-R available for LPS processing and clearance, as well as increased LPL activity through inhibition of Apo-CIII. PMID- 29174039 TI - Lavatera critica, a green leafy vegetable, controls high fat diet induced hepatic lipid accumulation and oxidative stress through the regulation of lipogenesis and lipolysis genes. AB - BACKGROUND: Lipid accumulation is the most vital risk factor for inducing nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome. Thus, the development of novel drugs is urgently needed to control obesity related diseases. OBJECTIVE: Here, we investigated the protective role of Lavatera critica (LC), a green vegetable, in male C57BL/6J mice fed with high fat (HF) diet for 10 weeks to induce hepatic lipid accumulation and oxidative cellular damage. RESULTS: After oral administration of chloroform (CFLC), ethyl acetate (EFLC), or methanol (MFLC) fractions of Lavatera critica to the HF group, EALC alone significantly reduced the activities of hepatic markers such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST); moreover, the results showed that 50 mg/kg dose has the maximum activity. Thus, this active dose of EFLC was used for further analysis. Moreover, EFLC reduced the level of hepatic triglycerides (TG), total cholesterol (TC), free fatty acids (FFA), and prevented further increase in the body weight. Intriguingly, EFLC treatment also reversed the mRNA expression of fatty acid oxidative genes, such as peroxisome proliferator activated receptor-alpha (PPAR-alpha), carnitine palmitoyltransferase-1 (CPT-1), and acetyl-CoA carboxylase (ACO), and fatty acid synthesis genes such as fatty acid synthase (FAS), sterol-regulatory-element binding protein-1c (SREBP-1c), and acetyl-CoA carboxylase (ACC). Furthermore, EFLC treatment also decreased the production of oxidative stress biomarkers, such as conjugated diene (CD), thiobarbituric acid reactive substances (TBARS), and lipid hydroperoxide (LOOH), and significantly enhanced the level of enzymatic antioxidants, such as glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase (CAT), as well as non-enzymatic antioxidants, such as reduced glutathione (GSH), vitamin C, and vitamin E in the liver. CONCLUSION: Taken together, we conclude that EFLC has a protective effect against HF diet induced hepatic lipid accumulation and oxidative cellular damage through the regulation of lipogenesis and lipolysis genes. PMID- 29174040 TI - The impact of the 2008 economic crisis on the increasing number of young psychiatric inpatients. AB - BACKGROUND: Little is published about the impact of the 2008 economic crisis on mental health services in Spain. METHOD: An interrupted time series analysis was conducted to investigate a potential short-term association between the 2008 economic crisis and the number of psychiatric hospital admissions. The timing of the intervention (April 2008) was based on observed changes in Gross Domestic Product (GDP). Data on 1,152,880 psychiatric inpatients from the national Hospital Morbidity Survey, 69 months before and after the onset of the economic crisis (April 2008), were analyzed. RESULTS: Age-adjusted psychiatric (ICD9 290 319) hospital discharge rates significantly increased from April 2008, matching the onset of the crisis, especially for inpatients aged 15-24 years old and to a less extend for inpatients aged 25-34 years old. Other age groups were not affected. There was a significant increase in diagnoses for disturbance of conduct and emotions, depression, neurotic and personality disorders and alcohol and drug disorders; however, diagnoses for mental retardation and organic psychosis for 15-34 years old inpatients were unaffected. CONCLUSIONS: Psychiatric hospital admissions abruptly increased in April 2008, coinciding with the onset of the economic crisis. We identified age groups and diagnoses affected. Increased hospitalizations were found only at the age-ranges most affected by the rise in unemployment. The diagnoses affected were those most sensitive to environmental changes. PMID- 29174041 TI - Quasi-static pulmonary P-V curves of patients with ARDS, Part I: Characterization. AB - Quasi-static, pulmonary pressure-volume (P-V) curves are combined with a respiratory system model to analyze characteristics of patients with acute respiratory distress syndrome (ARDS). It is shown that there exist distinct differences between healthy- and injured-respiratory system in the order of magnitudes of parameters of their P-V model equation. Four stages of ARDS (Early ARDS, Deep knee, Advanced ARDS and Baby lung) are defined quantitatively in terms of these parameters. PMID- 29174042 TI - Lipid Microbubbles as Ultrasound-Stimulated Oxygen Carriers for Controllable Oxygen Release for Tumor Reoxygenation. AB - Microbubbles are proposed as a potentially novel method for oxygen delivery in vivo in initial studies. The lack of commercial microbubbles for oxygen delivery in preclinical research prompted us to fabricate an oxygen-loaded lipid microbubble. We aimed to extend the innovative strategy to modulate the tumor hypoxic microenvironment, using microbubbles intravenously as an oxygen carrier for the controllable tumor-specific delivery of oxygen by ultrasound (US). In our experiment, an oxygen-loaded lipid-coated microbubble (OLM) with mixed gas (O2/C3 F8, 5:1 v/v) was fabricated and exhibited a higher rate of oxygen release to a desaturated solution through burst by US than that in the absence of US. Although in in vivo studies, OLMs could be imaged and triggered by US to elevate the pO2 level in the breast VX2 tumor dramatically within a matter of minutes. The added presence of US-activated OLMs elicited a nearly six-fold increase in pO2 levels within 1 min compared with that of the pre-injection. Owing to the high oxygen payload, great acoustic stability and acoustic properties, OLMs may be proposed as an ideal radio-sensitizer. We conclude that oxygen release mediated by ultrasound-targeted microbubble destruction is feasible and shows potential in image-guided, site-specific cancer radiotherapy. PMID- 29174043 TI - Quantitative Evaluation of Denervated Muscle Atrophy with Shear Wave Ultrasound Elastography and a Comparison with the Histopathologic Parameters in an Animal Model. AB - This study explored the efficacy of shear wave ultrasound elastography (SWUE) for quantitative evaluation of denervated muscle atrophy in a rabbit model. The elastic modulus of the triceps surae muscle was measured with SWUE and compared with histopathologic parameters at baseline and at various post-denervation times (2, 4 and 8 wk) with 10 animals in each group. Our results revealed that the elastic modulus of denervated muscle was significantly lower at 2 wk but higher at 8 wk compared with that at the baseline (p <0.05), and no significant difference was found between the elastic modulus at 4 wk and that at the baseline (p > 0.05). The wet-weight ratio and the muscle fiber cross-sectional area of the denervated muscle decreased gradually during the 8 wk post-denervation together with a gradual increase of the collagen fiber area (p <0.05). In conclusion, SWUE was useful for quantitative evaluation of muscle denervation. The decreased elastic modulus might be an early sign of denervated muscle atrophy. PMID- 29174044 TI - Repeatability of Contrast-Enhanced Ultrasonography of the Kidneys in Healthy Cats. AB - Contrast-enhanced ultrasound can be used to image and quantify tissue perfusion. It holds great potential for the use in the diagnosis of various diffuse renal diseases in both human and veterinary medicine. Nevertheless, the technique is known to have an inherent relatively high variability, related to various factors associated with the patient, the contrast agent and machine settings. Therefore, the aim of this study was to assess week-to-week intra- and inter-cat variation of several perfusion parameters obtained with CEUS of both kidneys of 12 healthy cats. Repeatability was determined by calculating the coefficient of variation (CV). The contrast-enhanced ultrasound parameters with the lowest variation for the renal cortex were time-to-peak (CV 6.0%), rise time (CV 13%), fall time (CV 19%) and mean transit time (24%). Intensity-related parameters and parameters related to the slope of the time-intensity curve had a CV of >35%. Lower repeatability was present for perfusion parameters derived from the renal medulla compared with the renal cortex. Normalization to the inter-lobar artery does not cause a reduction in variation. In conclusion, time-related parameters for the cortex show a reasonable repeatability; whereas poor repeatability is present for intensity-related parameters and parameters related to in- and outflow of contrast agent. Poor repeatability is also present for all perfusion parameters for the renal medulla, except for time to peak, which has a good repeatability. PMID- 29174046 TI - Simulation as a learning tool for continuing education on cardiorespiratory arrest. AB - OBJECTIVE: To evaluate the level of knowledge and the degree of satisfaction obtained through continuous training in simulation-debriefing methods as a learning tool in the care of cardiopulmonary arrest (CPA). METHOD: A quasi experimental study. Evaluation by ad hoc questionnaire (pre and post, and reassessment at 4 months) to all professionals (physicians and nurses) who passed any of the 6 editions of the course: 'Simulation of situations of cardiopulmonary arrest or peri-arrest in hospitalisation units'. Descriptive and inferential statistics. RESULTS: 133 participants, 16 physicians, and 117 nurses. Before the course started, the level of knowledge was 78.5%, at the end of training it was 94.6% (P<.001), and after 4 months, it was 88% (P<.05). The satisfaction achieved was 91.8% at the end of the course, and subsequently 88.4%; this was significant (P<.05) among the younger professionals, with less experience and with a temporary contract. Eighty one point two percent of the participants expressed that they changed the way they acted during a cardiopulmonary arrest. CONCLUSIONS: Continuous education in CPA, performed through simulation debriefing, is consolidated in our field as an effective tool to acquire a suitable level of knowledge that lasts over time. The level of satisfaction achieved was high since this method of learning meets the expectations of the professionals and resembles real care practice. PMID- 29174045 TI - Effect of Temperature on the Size Distribution, Shell Properties, and Stability of Definity(r). AB - Physical characterization of an ultrasound contrast agent (UCA) aids in its safe and effective use in diagnostic and therapeutic applications. The goal of this study was to investigate the impact of temperature on the size distribution, shell properties, and stability of Definity(r), a U.S. Food and Drug Administration-approved UCA used for left ventricular opacification. A Coulter counter was modified to enable particle size measurements at physiologic temperatures. The broadband acoustic attenuation spectrum and size distribution of Definity(r) were measured at room temperature (25 degrees C) and physiologic temperature (37 degrees C) and were used to estimate the viscoelastic shell properties of the agent at both temperatures. Attenuation and size distribution was measured over time to assess the effect of temperature on the temporal stability of Definity(r). The attenuation coefficient of Definity(r) at 37 degrees C was as much as 5 dB higher than the attenuation coefficient measured at 25 degrees C. However, the size distributions of Definity(r) at 25 degrees C and 37 degrees C were similar. The estimated shell stiffness and viscosity decreased from 1.76 +/- 0.18 N/m and 0.21 * 10-6 +/- 0.07 * 10-6 kg/s at 25 degrees C to 1.01 +/- 0.07 N/m and 0.04 * 10-6 +/- 0.04 * 10-6 kg/s at 37 degrees C, respectively. Size-dependent differences in dissolution rates were observed within the UCA population at both 25 degrees C and 37 degrees C. Additionally, cooling the diluted UCA suspension from 37 degrees C to 25 degrees C accelerated the dissolution rate. These results indicate that although temperature affects the shell properties of Definity(r) and can influence the stability of Definity(r), the size distribution of this agent is not affected by a temperature increase from 25 degrees C to 37 degrees C. PMID- 29174047 TI - Neonatal nurses' perceptions of pain management. AB - OBJECTIVES: To describe the perceptions of nurses in neonatal units on pain management, meet the educational profile and describe the use of pain assessment tools and non-pharmacological management for treatment. METHODS: Cross-sectional descriptive multicentre study, developed during the months of February to September 2015, in the neonatology services of three hospitals at the Community of Madrid, Spain. Data collection was performed through an ad hoc questionnaire on paper or electronically using Survey Monkey platform. RESULTS: The sample consisted of 142 professionals, with a response rate of 55%: 47.9% (68) confirmed they had received specific training in pain management; 39.5% (56) stated that pain is regularly assessed in the unit; only 43.6% reported using validated scales, the most used being the Premature Infant Pain Profile (PIPP). As for the non-pharmacological management, swaddling and non-nutritive sucking it is the most used, followed by sucrose. Intravenous cannulation was identified as the most painful procedure. CONCLUSIONS: Pain management is in the process of improvement, because of training and because there is little pain assessment using validated scales. The improvement in the use of non-pharmacological management for the relief of pain in minor procedures is noteworthy. PMID- 29174048 TI - Degradation of 2,4-dichlorophenol by activating persulfate and peroxomonosulfate using micron or nanoscale zero-valent copper. AB - The ability of persulfate (PS) and peroxymonosulfate (PMS) activated by micron or nanoscale zero-valent copper (ZVC or nZVC) to degrade 2,4-dichlorophenol (2,4 DCP) was quantified under various conditions. Mechanism investigation revealed that PS and PMS accelerated the corrosion of ZVC or nZVC to release Cu+ under acidic conditions. The in-situ generated Cu+ further decomposed PS or PMS to produce SO4- and OH, which then dramatically degraded 2,4-DCP. The kobs for 2,4 DCP removal followed pseudo-first-order kinetics, kobs of ZVC/PMS and nZVC/PMS systems were 10~30 times greater than these in ZVC/PS and nZVC/PS systems. The nZVC/PMS system was most effective to remove 2,4-DCP which even did better than the nZVI/PMS system, with rate constant values ranging from 0.041 to 1.855min-1. At higher pH ZVC is ineffective, but nZVC can activate PS and PMS to significantly degrade 2,4-DCP at pH up to 7.3. The 2,4-DCP degradation pathway was found to involve dechloridation, dehydrogenation, hydroxylation, ring open and mineralization. 56.7% and 45.3% of TOC removals were respectively obtained in the ZVC/PMS and nZVC/PMS systems within 120min. This study helps to comprehend the application of zero-valent metals in reactive radicals-based oxidation processes and the reactivity of Cu+ as an activator of PS and PMS. PMID- 29174049 TI - Neural responses to one's own name under mortality threat. AB - Recent behavioral research has shown evidence for greater inclination to avoid symbolic cues of mortality threats in nonbelievers than Christians. However, the neurocognitive mechanisms underlying religious influences on behavioral tendency to avoid mortality threats remain unknown. We tested the hypothesis of distinct arousal/attention-related brain responses to self-related information under mortality in nonbelievers and Christians. We recorded event-related brain potentials (ERPs) from Christians and nonbelievers while they viewed their own names and a stranger's name (i.e., Zuma) that flashed around a cue word (i.e., death, pain or life) located at the center of a screen. While own name vs. a stranger's name induced faster responses and larger P3 amplitudes, the P3 amplitudes to own name showed distinct patterns of modulations by the cue words in nonbelievers and Christians. Specifically, own name elicited larger P3 amplitudes in the death than pain/life cue conditions in nonbelievers but not in Christians. Moreover, the differential P3 amplitude to own names in the death vs. life cue conditions predicted greater inclination to avoid mortality threats in nonbelievers but not in Christians. Our findings provide a neurocognitive account of increased behavioral tendency to avoid mortality threats in nonbelievers than in Christians. PMID- 29174050 TI - Phonological working memory and FOXP2. AB - The discovery and description of the affected members of the KE family (aKE) initiated research on how genes enable the unique human trait of speech and language. Many aspects of this genetic influence on speech-related cognitive mechanisms are still elusive, e.g. if and how cognitive processes not directly involved in speech production are affected. In the current study we investigated the effect of the FOXP2 mutation on Working Memory (WM). Half the members of the multigenerational KE family have an inherited speech-language disorder, characterised as a verbal and orofacial dyspraxia caused by a mutation of the FOXP2 gene. The core phenotype of the affected KE members (aKE) is a deficiency in repeating words, especially complex non-words, and in coordinating oromotor sequences generally. Execution of oromotor sequences and repetition of phonological sequences both require WM, but to date the aKE's memory ability in this domain has not been examined in detail. To do so we used a test series based on the Baddeley and Hitch WM model, which posits that the central executive (CE), important for planning and manipulating information, works in conjunction with two modality-specific components: The phonological loop (PL), specialized for processing speech-based information; and the visuospatial sketchpad (VSSP), dedicated to processing visual and spatial information. We compared WM performance related to CE, PL, and VSSP function in five aKE and 15 healthy controls (including three unaffected members of the KE family who do not have the FOXP2 mutation). The aKE scored significantly below this control group on the PL component, but not on the VSSP or CE components. Further, the aKE were impaired relative to the controls not only in motor (i.e. articulatory) output but also on the recognition-based PL subtest (word-list matching), which does not require speech production. These results suggest that the aKE's impaired phonological WM may be due to a defect in subvocal rehearsal of speech-based material, and that this defect may be due in turn to compromised speech-based representations. PMID- 29174051 TI - Body mass estimation from the skeleton: An evaluation of 11 methods. AB - Estimating an individual body mass (BM) from the skeleton is a challenge for forensic anthropology. However, identifying someone's BMI (Body Mass Index) category, i.e. underweight, normal, overweight or obese, could contribute to identification. Individual BM is also known to influence the age-at-death estimation from the skeleton. Several methods are regularly used by both archaeologists and forensic practitioners to estimate individual BM. The most commonly used methods are based on femoral head breadth, or stature and bi-iliac breadth. However, those methods have been created from mean population BMs and are therefore meant to estimate the average BM of a population. Being that they are based on individual BM data and estimated femoral cortical areas, the newest published methods are supposed to be more accurate. We evaluated the accuracy and reliability of the most commonly used and most recent BM estimation methods (n=11) on a sample of 64 individuals. Both sexes and all BMI categories are represented, as well as a wide range of BM. Ages in this sample range from 20 to 87 years of age. Absolute and real differences between actual BM and estimated BM were assessed; they determined the accuracy for individual BM estimation and for average BM estimation of a population, respectively. The proportion of the sample whose estimated BM falls within +/-10% and +/-20% of their actual BM determines the reliability of the methods in our sample for, respectively, individual BM estimation and average BM of a population. The tested methods result in an absolute difference of 11kg-26kg+/-10kg with regards to prediction of individuals actual BM. The real differences are very variable from method to method, ranging from -14kg to 25kg. None of the tested methods is able to estimate BM of half of the sample within +/-10% of their actual BM but most of them can estimate BM of more than half of the sample within +/-20% of their actual BM. The errors increase with increasing BM, demonstrating a bias in all the methods. No bone variable tested correlated with BM. BMI categories were correctly predicted for less than 50% of the sample in most cases. In conclusion, our study demonstrates that the 11 methods tested are not suited for estimating individual BM or for predicting BMI categories. However, they are accurate and reliable enough for estimating the average BM of a population. PMID- 29174052 TI - Development and validation of a Partial Least Squares-Discriminant Analysis (PLS DA) model based on the determination of ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEEs) in hair for the diagnosis of chronic alcohol abuse. AB - The chronic intake of an excessive amount of alcohol is currently ascertained by determining the concentration of direct alcohol metabolites in the hair samples of the alleged abusers, including ethyl glucuronide (EtG) and, less frequently, fatty acid ethyl esters (FAEEs). Indirect blood biomarkers of alcohol abuse are still determined to support hair EtG results and diagnose a consequent liver impairment. In the present study, the supporting role of hair FAEEs is compared with indirect blood biomarkers with respect to the contexts in which hair EtG interpretation is uncertain. Receiver Operating Characteristics (ROC) curves and multivariate Principal Component Analysis (PCA) demonstrated much stronger correlation of EtG results with FAEEs than with any single indirect biomarker or their combinations. Partial Least Squares Discriminant Analysis (PLS-DA) models based on hair EtG and FAEEs were developed to maximize the biomarkers information content on a multivariate background. The final PLS-DA model yielded 100% correct classification on a training/evaluation dataset of 155 subjects, including both chronic alcohol abusers and social drinkers. Then, the PLS-DA model was validated on an external dataset of 81 individual providing optimal discrimination ability between chronic alcohol abusers and social drinkers, in terms of specificity and sensitivity. The PLS-DA scores obtained for each subject, with respect to the PLS DA model threshold that separates the probabilistic distributions for the two classes, furnished a likelihood ratio value, which in turn conveys the strength of the experimental data support to the classification decision, within a Bayesian logic. Typical boundary real cases from daily work are discussed, too. PMID- 29174053 TI - Mitochondria-targeted cationic porphyrin-triphenylamine hybrids for enhanced two photon photodynamic therapy. AB - The proof of concept for two-photon activated photodynamic therapy has already been achieved for cancer treatment but the efficiency of this approach still heavily relies on the availability of photosensitizers combining high two-photon absorption and biocompatibility. In this line we recently reported on a series of porphyrin-triphenylamine hybrids which exhibit high singlet oxygen production quantum yield as well as high two-photon absorption cross-sections but with a very poor cellular internalization. We present herein new photosensitizers of the same porphyrin-triphenylamine hybrid series but bearing cationic charges which led to strongly enhanced water solubility and thus cellular penetration. In addition the new compounds have been found localized in mitochondria that are preferential target organelles for photodynamic therapy. Altogether the strongly improved properties of the new series combined with their specific mitochondrial localization lead to a significantly enhanced two-photon activated photodynamic therapy efficiency. PMID- 29174054 TI - Effect of polyphenols from coffee and grape on gene expression in myoblasts. AB - Coffee and grape contain various bioactive compounds like polyphenols that may exert beneficial effects, especially antioxidant activity, on human health upon consumption. However, the molecular mechanisms through which these effects are achieved are not fully elucidated. Thus, in the present study in order to investigate these mechanisms, a whole genome expression DNA microarray analysis was carried out in myoblasts treated with polyphenols of coffee and grape pomace at concentrations that improved the redox status. Grape was composed of catechin, epicatechin, cyanidin, malvidin, delphinidin, petunidin, myrtillin, kuromanin, oenin, peonidin, quercetin, gallic acid and caftaric acid as LC-MS revealed, with a total polyphenolic content (TPC) of 648 mg of gallic acid equivalents/g of dry matter. Coffee had a TPC of 42.61 mg GAE/g coffee and was composed of 3 chlorogenic acid (16.61 mg/g), 4- and 5-chlorogenic acids (13.62 mg/g), as UHPLC HRMS revealed. According to the results, grape polyphenols altered mainly the expression of cytoskeleton and differentiation-associated genes, while coffee compounds had a more profound effect, on the expression levels of many metabolic and antioxidant genes possibly through the nuclear factor (erythroid-derived 2) like-2 (Nrf2) pathway. PMID- 29174055 TI - Regression equations for the estimation of stature and body mass using a Greek documented skeletal collection. AB - Body size is an important variable in bioarchaeological and forensic studies, making the accurate calculation of stature and body mass imperative. Given that anatomical and morphometric approaches offer accurate results but require a particularly good preservation of the skeletal material, whereas mathematical and mechanical methods are more easily applicable but they are largely population specific, the present paper uses a 'hybrid' approach in order to generate regression equations for the prediction of stature and body mass in a modern Greek sample. Specifically, anatomical and morphometric methods were used to calculate the stature and body mass of the individuals and regression equations using the Ordinary Least Squares and Reduced Major Axis methods were generated with long bone lengths and femoral head breadth as predictors. The obtained equations exhibit low random and directional error and perform better than existing equations designed using different samples from the United States, Europe, and the Balkans. Therefore, these equations are more appropriate for modern Greek material. PMID- 29174056 TI - Impact of the time interval from completion of neoadjuvant chemotherapy to initiation of postoperative adjuvant chemotherapy on the survival of patients with advanced ovarian cancer. AB - OBJECTIVE: To investigate the relationship of the time interval from the completion of neoadjuvant chemotherapy (NAC) to the initiation of postoperative adjuvant chemotherapy (POAC) with the survival outcomes in patients with ovarian cancer. METHODS: We retrospectively investigated 220 patients with pathologically confirmed epithelial ovarian cancer who received NAC at Yonsei Cancer Hospital between 2006 and 2016. The time interval was defined as the period from the completion of NAC, spanning interval debulking surgery (IDS), to the initiation of POAC. RESULTS: The median time interval was 42 (range 16-178) days; 103 patients (53.1%) received POAC within 42days after NAC while 91 patients (46.9%) received it after 42days. There were no significant differences in patient characteristics between these 2 groups. Kaplan-Meier analysis showed that patients with longer time intervals (>42days) had poorer progression-free survival and overall survival (P=0.039 and 0.005, respectively). In the multivariate analysis, patients with longer time intervals had significantly poorer progression-free (hazard ratio, 1.41; 95% confidence interval, 0.98-2.03; not significant) and overall survivals (hazard ratio, 2.03; 95% confidence interval, 1.16-3.54). When the patients were categorized according to time interval quartiles (<=37, 38-42, 43-50, and >50days), longer time intervals were associated with higher risks of recurrence and death (P for trend: 0.006 and <0.001, respectively). CONCLUSION: The time interval from the completion of NAC to the initiation of POAC appears to influence survival. Efforts to reduce the time interval might improve the outcomes in ovarian cancer patients undergoing NAC. PMID- 29174057 TI - Curbing opioid requirements after inguinal hernia repair. PMID- 29174058 TI - Intraoperative parathormone spikes during parathyroidectomy may be associated with multiglandular disease. AB - BACKGROUND: The importance of intraoperative parathormone "spikes" during parathyroidectomy remains unclear. This study compared patients with and without intraoperative parathormone spikes during parathyroidectomy using the criterion of a > 50% parathormone and determined the effect of intraoperative parathormone spikes on operative outcome. METHODS: We performed a retrospective review of prospectively collected data on 683 patients who underwent parathyroidectomy guided by intraoperative parathormone monitoring. An intraoperative parathormone "spike value" was calculated by subtracting the preincision intraoperative parathormone value from the pre-excision intraoperative parathormone value (SV = PE - PI). An intraoperative parathormone spike was defined as having a positive spike value >=9 pg/mL (>=10th percentile of all spike values). RESULTS: Of 683 patients, 224 (33%) had intraoperative parathormone spikes and a greater rate of multiglandular disease (8% vs. 3%, P < 0.05) and bilateral neck exploration (10% vs. 5%, P < 0.05) compared with patients without intraoperative parathormone spikes. Overall, there were no differences between parathyroidectomy patients with and without intraoperative parathormone spikes in terms of operative success (98.2% vs. 98.0%), failure (1.8% vs. 2.0%), or recurrence rates (0.4% vs. 1.3%). CONCLUSIONS: Although the presence of intraoperative parathormone spikes may increase suspicion for multiglandular disease, the ability of intraoperative parathormone monitoring to predict operative success after parathyroidectomy is not affected by spikes. PMID- 29174059 TI - Vibratory movements in contests between females of the feather-legged spider (Uloborus plumipes). AB - Females of the feather-legged spider Uloborus plumipes invade, and compete for, each other's orb webs. In the context of these competitive interactions the question arose how the spiders communicate. Since substrate-borne vibrations are the most important component of the sensory environment of web-building spiders, we investigated vibratory movements that might serve as signals of communication. Three behaviors were found to be associated with female-female contests and to cause propagating vibrations in the spider webs: thread pulling, abdominal trembling, and web shaking. While thread pulling and abdominal trembling were also observed when prey insects were caught in the webs, web shaking occurred only in response to the presence of a competing conspecific. Caused by flexing of the first legs and a vigorous rotary movement of the opisthosoma, web shaking creates a short burst of strong oscillations of the orb web. This behavior always elicited a behavioral reaction by the competitor and may serve as an intraspecific signal in the mutual assessment of competing spiders. We suggest that web shaking communicates resource holding potential in U. plumipes. PMID- 29174060 TI - Feasibility of a 6-Month Yoga Program to Improve the Physical and Psychosocial Status of Persons with Multiple Sclerosis and their Family Members. AB - CONTEXT: To the best of our knowledge, there has been no study on yoga that includes both persons with multiple sclerosis (MS) and their family members. Because yoga has therapeutic effects in both persons with MS and healthy persons, we hypothesized that it would be an effective method to improve not only the physical and psychosocial status but also the time persons with MS and their family members spend together. OBJECTIVE: To examine the feasibility of a 6-month (long-term) yoga program to improve the physical and psychosocial status of persons with MS and their family members. DESIGN: Uncontrolled clinical trial. SETTING: The protocol was developed at the Department of Neurology, Faculty of Medicine, and School of Physical Therapy and Rehabilitation, Dokuz Eylul University, Izmir, Turkey. PARTICIPANTS: Persons with MS and healthy family members. MAIN OUTCOME MEASURES: Walking, balance, fatigue, health-related quality of life, depression, pain, and kinesiophobia. INTERVENTIONS: Yoga training was given once a week (at least 1h) for 6 months. The same assessors who assessed at baseline also performed the same assessments immediately after the end of the training (i.e., after 6 months). RESULTS: In total, 44 participants (27 persons with MS and 17 healthy family members) participated in the study. Twelve persons with MS and three healthy family members completed the 6-month yoga intervention. The completion rate for persons with MS and healthy subjects was 44.4% and 17.6%, respectively. In persons with MS, the mental dimension of health-related quality of life, walking speed, fatigue, and depression levels significantly improved after the yoga program (p < .05). However, there was no significant change in the self-reported walking impact, balance, pain, physical dimension of health-related quality of life, and kinesiophobia levels in the persons with MS (p > .05). This study suggests that a 6-month yoga program can improve the mental dimension of health-related quality of life, walking speed, fatigue, and depression in the persons with MS. However, the 6-month yoga program does not appear to be a feasible method to increase the time that persons with MS spend together with their family members. PMID- 29174062 TI - Tiotropium Respimat Add-on Is Efficacious in Symptomatic Asthma, Independent of T2 Phenotype. AB - BACKGROUND: Adding tiotropium to existing inhaled corticosteroid (ICS) maintenance therapy with or without a long-acting beta2-agonist (LABA) has been shown to be beneficial in patients with symptomatic asthma. OBJECTIVE: To assess whether responses to tiotropium Respimat add-on therapy were influenced by patients' T2 status. METHODS: In this exploratory study, data from 4 phase III trials were analyzed: once-daily tiotropium 5 MUg or placebo as add-on to ICS + LABA (PrimoTinA-asthma; 2 replicate trials; NCT00772538/NCT00776984; n = 912); once-daily tiotropium 5 MUg or 2.5 MUg, twice-daily salmeterol 50 MUg, or placebo as add-on to ICS (MezzoTinA-asthma; 2 replicate trials; NCT01172808/NCT01172821; n = 2100). The prespecified efficacy outcomes of these studies have been reported previously. Here, further exploratory subgroup analyses were performed to study whether these coprimary end points were influenced by serum IgE levels, blood eosinophil counts, and clinician judgment of allergic asthma. In addition, for the continuous parameters, namely, IgE and blood eosinophils, their influence on the treatment effect was modeled over the whole range of values. RESULTS: Tiotropium was efficacious in improving peak FEV1 within 3 hours postdose and trough FEV1, independent of T2 status. Tiotropium significantly reduced the risk of severe asthma exacerbations and asthma worsening, independent of T2 phenotype; Cox regression modeling supported a beneficial effect of tiotropium on exacerbations, independent of IgE levels or eosinophil counts. Numerical improvements in the 7-question Asthma Control Questionnaire (ACQ-7) responder rate with tiotropium versus placebo were observed in T2high and T2low patients; logistic regression modeling provided further evidence for improvement in ACQ-7 responder rates with tiotropium, independent of IgE levels or eosinophil counts. CONCLUSIONS: The results of our exploratory analyses suggest that the improvements seen with tiotropium Respimat as add-on to ICS +/- LABA in patients with symptomatic asthma on lung function, exacerbation risk, and symptom control are independent of T2 phenotype. PMID- 29174061 TI - Pathobiological expression of the brain-derived neurotrophic factor (BDNF) in cerebellar cortex of sudden fetal and infant death victims. AB - Brain-derived neurotrophic factor (BDNF), a neurotrophin of the central nervous system, is able to regulate neuronal differentiation and modulate synaptic plasticity, being particularly involved in the development of the cerebellar cortical structure. The main aim of this study was to delineate, by immunohistochemistry, the BDNF expression in human cerebellar cortex of victims of fetal and infant death. The study was performed on a total of 45 cases, aged between 25 gestational weeks and 6 postnatal months, including 29 victims of sudden fetal and infant death and 16 age-matched subjects who died of known causes (Controls). We observed, in sudden death groups compared with Controls, a significantly higher incidence of defective BDNF expression in granule layers of the cerebellar cortex, which was particularly evident in the posterior lobule, a region that participates in respiratory control. These results were related to maternal smoking, allowing to speculate that nicotine, in addition to the well known damages, can exert adverse effects during cerebellar cortex development, in particular in hindering the BDNF expression in the posterior lobule. This implies modifications of synaptic transmission in the respiratory circuits, with obvious deleterious consequences on survival. PMID- 29174063 TI - Health Care Resource Utilization and Costs Among Adults with Atopic Dermatitis in the United States: A Claims-Based Analysis. AB - BACKGROUND: Data on health care resource utilization (HCRU) and costs for patients with atopic dermatitis (AD) are lacking. OBJECTIVE: The objective of this study was to determine HCRU and costs associated with AD in US adults. METHODS: This retrospective study identified patients with AD from the Truven Health Marketscan Commercial Claims and Encounters database during 2013 based on >=2 claims with International Classification of Diseases, Ninth Revision code 691.8 (n = 10,533; first claim = index event); 1-year continuous enrollment before and after index was required. Patients were age- and gender-matched in a 1:3 ratio to controls without AD (n = 31,599). Patients with AD were further categorized into 2 groups, with treatment regimens as surrogates for increasing disease severity: claim for phototherapy or systemic immunomodulatory agents (more severe) or no claim for either (less severe). Incremental differences in resource use and costs were evaluated using multivariate analysis. RESULTS: AD was associated with higher utilization and costs across resource categories (all P < .0001); adjusted total incremental annual costs were $3,302. Resource utilization and costs were higher in the more severe group, with adjusted total incremental annual costs of $4,463. CONCLUSION: AD is associated with significant incremental health care utilization and costs, which are higher in patients with more severe disease. PMID- 29174064 TI - The health economics of ankle and foot sprains and fractures: A systematic review of English-language published papers. Part 2: The direct and indirect costs of injury. AB - BACKGROUND: Ankle and foot sprains and fractures are prevalent injuries, which may result in substantial physical and economic consequences for the patient and place a financial burden on the health care system. Therefore, the objectives of this paper are to examine the direct and indirect costs of treating ankle and foot injuries (sprains, dislocations, fractures), as well as to provide an overview of the outcomes of full economic analyses of different treatment strategies. METHODS: A systematic review was carried out among seven databases to identify English language publications on the health economics of ankle and foot injury treatment published between 1980 and 2014. The direct and indirect costs were abstracted by two independent reviewers. All costs were adjusted for inflation and reported in 2016 US dollars (USD). RESULTS: Among 2047 identified studies, 32 were selected for analysis. The direct costs of ankle sprain management ranged from $292 to $2268 per patient (2016 USD), depending on the injury severity and treatment strategy. The direct costs of managing ankle fractures were higher ($1908-$19,555). Foot fracture treatment had similar direct costs ranging from $998 to $21,801. The economic evaluations were conducted from the societal or payer's perspectives. CONCLUSION: The costs of treating ankle and foot sprains and fractures varied among the studies, mostly due to differences in injury type and study characteristics, which impacted the ability of directly comparing the financial burden of treatment. Nonetheless, the review showed that the costs experienced by the patient and the health care system increased with injury complexity.

PMID- 29174066 TI - A flexible control system designed for lab-scale simulations and optimization of composting processes. AB - Understanding and optimization of composting processes can benefit from the use of controlled simulators of various scales. The Agricultural Research Organization Composting Simulator (ARO-CS) was recently built and it is flexibly automated by means of a programmable logic controller (PLC). Temperature, carbon dioxide, oxygen and airflow are monitored and controlled in seven 9-l reactors that are mounted into separate 80-l water baths. The PLC program includes three basic heating modes (pre-determined temperature profile, temperature-feedback ("self-heating"), and carbon dioxide-dependent temperature), three basic aeration modes (airflow dependence on temperature, carbon dioxide, or oxygen) and enables all possible combinations among them. This unique high flexibility provides a robust and valuable research tool to explore a wide range of research questions related to the science and engineering of composting. In this article the logic and flexibility of the control system is presented and demonstrated and its potential applications are discussed. PMID- 29174067 TI - Recycled concrete aggregate as road base: Leaching constituents and neutralization by soil Interactions and dilution. AB - Recycled Concrete Aggregate (RCA) is often used as a replacement for natural aggregate in road construction activities because of its excellent mechanical properties, and this trend should increase as more transportation departments include RCA in specifications and design manuals. Concerns raised by some engineers and contractors include impacts from leachate generated by RCA, both from transport of metals to water sources and the impact of a high pH leachate on corrosion of underlying metal drainage pipes. In this study, RCA collected from various regions of Florida exhibited pH ranging from 10.5 to 12.3. Concentrations of Al, Ba, Cr, Fe, Mo, Na, Ni, Sb, and Sr measured using batch leaching tests exceeded applicable risk-based thresholds on at least some occasions, but the concentrations measured suggest that risk to water supplies should be controlled because of dilution and attenuation. Two mechanisms of pH neutralization were evaluated. Soil acidity plays a role, but laboratory testing and chemical modeling found that at higher liquid-to-solid ratios the acidity is exhausted. If high pH leachate did reach groundwater, chemical modeling indicated that groundwater dilution and carbonation would mitigate groundwater pH effects. PMID- 29174068 TI - [The impact of therapeutic inertia and the degree of the medication adherence on the control goals for patients with diabetes]. AB - OBJECTIVE: The purpose of this study was to analyse both the impact of low therapeutic adherence (TA) and therapeutic inertia (TI) on poor blood glucose control and on risk factors for heart disease in patients with DM2. MATERIAL AND METHODS: A cross-sectional study was conducted in a Primary Halth Care centre. A total of 320 patients with DM2 were included and an assessment was made of control goals (HbA1c<=7%, blood pressure <=130/80mmHg, and LDL cholesterol<=100mg/dl). A pharmacy retrieval <80% was considered as a lack of TA and the non-modification of treatment in badly controlled patient as TI. RESULTS: The percentage of patients with good control of HbA1c, blood pressure and LDL cholesterol was 62.5%, 40.9%, and 35.9%, respectively. Lower figures of TA were present in poorly controlled patients, and TI was not found to be related to TA. In the patients with poor HbA1c control, 25.8% had TI, 24.8% poor TA, and 11.9% had both of them. As regards LDL-cholesterol, 3.6% presented poor TA, 70.4% showed TI, and 16% with poor TA and TI (P<.001). As for blood pressure, 3.5% of patients had poor TA, 54.6% had TI, and 21.5% of them had poor TA as well as TI (P<.01). CONCLUSIONS: Lack of therapeutic adherence and therapeutic inertia were found in a high percentage of poorly-controlled DM2 patients with bad control. Therapeutic inertia was found to be of great relevance in this study.

AB - Severe hypertriglyceridemia is the third most common cause of acute pancreatitis and is strongly associated with an increased risk of cardiovascular disease. In infants, the most common cause of severe hypertriglyceridemia is lipoprotein lipase deficiency. We describe a 7-week-old infant with severe hypertriglyceridemia, who presented with frequent gastrointestinal bleeding, respiratory distress, a decreased level of consciousness and lipemia retinalis. Triglycerides were reduced from 734 to 2 mmol/L (64,956-177 mg/dL), by exchange transfusions. The infant made a remarkable recovery with no sequelae. This case highlights atypical, protean presentations and a potential treatment when established therapies are unavailable. PMID- 29174070 TI - ACS NSQIP risk calculator reliability in head and neck oncology: The effect of prior chemoradiation on NSQIP risk estimates following laryngectomy. AB - PURPOSE: To determine whether inclusion of chemoradiation history increases estimated risk for complications following total laryngectomy using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) Surgical Risk Calculator. MATERIALS AND METHODS: A retrospective review of 96 patients with laryngeal cancer, approximately half of who had received prior chemoradiation, who underwent laryngectomy between January 2010 and December 2014. NSQIP estimates were calculated and compared to actual event occurrence using receiver operating characteristic (ROC) curves, Brier scores, and risk estimates. RESULTS: Patients who had received prior chemoradiation were at significantly greater risk for complication postoperatively (OR=2.63, 95% CI=1.145-6.043). NSQIP Calculator discriminability and accuracy were generally poor for this sample. While NSQIP estimates significantly predicted risk for any postoperative complication, pneumonia, and discharge to nursing care for primary laryngectomy patients, predictive capability was lost among salvage laryngectomy patients. NSQIP adjustments to both Somewhat Higher and Significantly Higher Risk categories did not improve predictive capability. Of the risk factors considered by NSQIP, preoperative functional status (p=0.041), age at time of surgery (p<0.008), and inclusion of neck dissection (p=0.035) emerged as significant predictors of actual postoperative complications, though again estimates lost significance among salvage laryngectomy patients. CONCLUSIONS: The NSQIP Calculator may be poorly calibrated to estimate postoperative complication risk for patients previously exposed to chemoradiation undergoing salvage laryngectomy. Caution should be used when estimating postoperative risk among patients undergoing salvage procedures, especially those of older age, poorer functional status, and those requiring neck dissection.

PMID- 29174073 TI - Lumbar Medial Branch Block Volume-Dependent Dispersion Patterns as a Predictor for Ablation Success: A Cadaveric Study. AB - BACKGROUND: Lumbar facet arthropathy is a common cause of low back pain. Literature supports treatment with radiofrequency ablation (RFA) of associated nerves that innervate lumbar facets when alternative conservative therapies have failed. Diagnostic local anesthetic blocks precede therapeutic ablation, but have a false-positive rate of 27%-63%, and some authors have questioned their utility in predicting therapeutic response to RFA. The authors of the current study believe that injectate volume may be a contributing factor to false positivity. OBJECTIVE: To evaluate the difference in volume dispersion between 0.25 mL and 0.5 mL of injectate when performing lumbar medial branch blocks. We hypothesized that injection volumes greater than 0.25 mL during lumbar medial branch blocks would affect the distal branches of the adjacent medial branches, thus decreasing the specificity of the procedure. Thus, we attempted to demonstrate that injection volumes greater than 0.25 mL during lumbar medial branch blocks would affect the distal branches of the adjacent medial branches, which might increase false positivity of the blocks. STUDY DESIGN: Cadaveric investigation. SETTING: Tertiary care center. PARTICIPANTS: Not applicable. OUTCOME MEASUREMENTS: To demonstrate that the spread of lumbar medial branch blocks using commonly injected volume coats adjacent structures that are not affected by radiofrequency ablation. METHODS: Six cadavers were chosen with nondissected lumbar spines. Fluoroscopically guided medial branch injections were performed bilaterally using the posterior oblique approach. A volume of 0.25 mL or 0.50 mL of a 9:1 solution of Omnipaque 240 and 1% medical grade methylene blue were delivered to the left and right sides, respectively. Postinjection computed tomographic imaging was performed, followed by dissection. RESULTS: Both volumes adequately coated the medial branches, but in the 0.5-mL injectate cohort there was consistent spread dorsally to the superficial muscles and distal segments of the dorsal branches distant to the target nerves, whereas in the 0.25-mL injectate cohort the spread was contained in the deep and intermediate muscular lumbar layers, close to the intended target. CONCLUSION: We suggest that a 0.5-mL injectate volume in clinical practice may produce an adjacent-level nerve block in addition to the intended injection level, thus decreasing the specificity of a targeted lumbar medial branch block. A 0.25-mL quantity of injectate reliably contacted the lumbar medial branches without extensive extravasation. Presumably, this means that 0.25 mL total volume for a lumbar medial branch block may provide greater specificity for RFA planning. LEVEL OF EVIDENCE: NA.

PMID- 29174076 TI - Characteristics and Progression of Hearing Loss in Children with Down Syndrome. AB - OBJECTIVES: To evaluate hearing impairment in children with Down syndrome, and to describe the factors that influence the severity of hearing loss or changes in hearing over time. STUDY DESIGN: Using the Audiological and Genetic Database (AudGenDB), audiograms of children with Down syndrome were analyzed retrospectively for type, severity, and laterality of hearing loss, as well as changes over time. Medical charts and imaging results were reviewed to identify factors influencing hearing loss. RESULTS: Among the 1088 patients with Down syndrome included in the study, 921 had hearing loss in at least 1 ear, 91.1% had bilateral hearing loss, and 8.9% had unilateral hearing loss (1760 total ears with hearing loss). Of the ears with hearing loss, 18.8% (n = 180) had moderate or worse hearing loss. "Undefined" hearing loss and pure conductive hearing loss (CHL) were the most common types, followed by mixed hearing loss and sensorineural hearing loss (SNHL). Three-quarters (75.4%) of the children had experienced chronic otitis media or more than 2 episodes of acute otitis media. Patients with bilateral, mixed hearing loss or a history of seizures were at risk for more severe hearing loss. CHL, absence of cholesteatoma, and placement of first ear tubes before age 2 years were associated with greater improvement in hearing over time, whereas SNHL and mixed hearing loss were associated with progressive decline. CONCLUSION: Children with Down syndrome who have bilateral, mixed hearing loss or a history of seizures are at risk for more severe hearing loss. SNHL and mixed hearing loss should not be overlooked in patients with CHL. All patients with Down syndrome will benefit from serial audiograms, especially those children with SNHL or mixed hearing loss, which is likely to worsen over time.

AB - OBJECTIVES: To evaluate national health care use and costs for pediatric acute pancreatitis. STUDY DESIGN: The Kids' Inpatient Database for 2006, 2009, and 2012 was queried for patients with a principal diagnosis of acute pancreatitis. Cases were grouped by age: preschool (<5 years of age), school age (5-14 years of age), and adolescents (>14 years of age). RESULTS: A total of 27 983 discharges for acute pancreatitis were found. The number of admissions increased with age: young n = 1279, middle n = 8012, and older n = 18 692. Duration of stay was highest in preschool children (median, 3.47 days; IQR, 2.01-7.35), compared with school age (median, 3.22 days; IQR, 1.81-5.63) and adolescents (median, 2.87 days; IQR, 1.61 4.81; P < .001). The median cost of hospitalization varied with age: $6726 for preschoolers, $5400 for school-aged children, and $5889 for adolescents (P < .001). Acute pancreatitis-associated diagnoses varied by age. The presence of gallstone pancreatitis, alcohol, and hypertriglyceridemia was more common among older children compared with younger children (P < .001). There was an increasing trend in acute pancreatitis, chronic pancreatitis, and obesity for the 2 older age groups (P < .001). CONCLUSION: Admission of children for acute pancreatitis constitutes a significant healthcare burden, with a rising number of admissions with age. However, the cost and duration of stay per admission are highest in young children. PMID- 29174079 TI - Laryngeal Mask Airway for Surfactant Administration in Neonates: A Randomized, Controlled Trial. AB - OBJECTIVE: To determine if preterm infants with moderate respiratory distress syndrome on continuous positive airway pressure (CPAP) who received surfactant via a laryngeal mask airway (LMA) would have a decreased rate of intubation and mechanical ventilation compared with those on CPAP who did not receive surfactant. STUDY DESIGN: In this prospective, multicenter, randomized controlled trial, 103 premature infants 280/7-356/7 weeks gestation, >=1250 g and <=36 hours old on CPAP requiring fraction of inspired oxygen 0.30-0.40 were assigned to receive surfactant administered through an LMA then placed back on CPAP (LMA group) or maintained on CPAP with no surfactant administered (control group). The primary outcome was treatment failure necessitating intubation and mechanical ventilation in the first 7 days of life. RESULTS: Surfactant administration through an LMA (n = 50) significantly decreased the rate of intubation and mechanical ventilation compared with controls (n = 53): 38% vs 64%, respectively, OR 0.30 (95% CI 0.13, 0.70), P = .006, number needed to treat: 4). There were no serious adverse events associated with placement of the LMA or surfactant administration. CONCLUSIONS: In premature neonates with moderate respiratory distress syndrome, surfactant administered through an LMA decreased the rate of intubation and mechanical ventilation. This intervention may have significant impact on clinical care in both high and low resource settings. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01116921. PMID- 29174080 TI - Patterns of Care at the End of Life for Children and Young Adults with Life Threatening Complex Chronic Conditions. AB - OBJECTIVE: To characterize patterns of care at the end of life for children and young adults with life-threatening complex chronic conditions (LT-CCCs) and to compare them by LT-CCC type. STUDY DESIGN: Cross-sectional survey of bereaved parents (n = 114; response rate of 54%) of children with noncancer, noncardiac LT CCCs who received care at a quaternary care children's hospital and medical record abstraction. RESULTS: The majority of children with LT-CCCs died in the hospital (62.7%) with more than one-half (53.3%) dying in the intensive care unit. Those with static encephalopathy (AOR, 0.19; 95% CI, 0.04-0.98), congenital and chromosomal disorders (AOR, 0.28; 95% CI, 0.09-0.91), and pulmonary disorders (AOR, 0.08; 95% CI, 0.01-0.77) were significantly less likely to die at home compared with those with progressive central nervous system (CNS) disorders. Almost 50% of patients died after withdrawal or withholding of life-sustaining therapies, 17.5% died during active resuscitation, and 36% died while receiving comfort care only. The mode of death varied widely across LT-CCCs, with no patients with pulmonary disorders dying receiving comfort care only compared with 66.7% of those with CNS progressive disorders. A majority of patients had palliative care involvement (79.3%); however, in multivariable analyses, there was distinct variation in receipt of palliative care across LT-CCCs, with patients having CNS static encephalopathy (AOR, 0.07; 95% CI, 0.01-0.68) and pulmonary disorders (AOR, 0.07; 95% CI, 0.01-.09) significantly less likely to have palliative care involvement than those with CNS progressive disorders. CONCLUSIONS: Significant differences in patterns of care at the end of life exist depending on LT-CCC type. Attention to these patterns is important to ensure equal access to palliative care and targeted improvements in end-of-life care for these populations. PMID- 29174081 TI - Tdap Vaccination Among Healthcare Personnel-21 States, 2013. AB - INTRODUCTION: Outbreaks of pertussis can occur in healthcare settings. Vaccinating healthcare personnel may be helpful in protecting healthcare personnel from pertussis and potentially limiting spread to others in healthcare settings. METHODS: Data from 21 states using the 2013 Behavioral Risk Factor Surveillance System industry/occupation module were analyzed in 2016. Tetanus, diphtheria, and acellular pertussis (Tdap) vaccination status was self-reported by healthcare personnel along with their occupation, healthcare setting/industry, demographics, and access to care factors. To compare groups, t-tests were used. The median state response rate was 44.0%. RESULTS: Among all healthcare personnel, 47.2% were vaccinated for Tdap. Physicians had higher Tdap coverage (66.8%) compared with all other healthcare personnel except nurse practitioners and registered nurses (59.5%), whose coverage did not statistically differ from that of physicians. Tdap vaccination coverage was higher among workers in hospitals (53.3%) than in long-term care facilities (33.3%) and other clinical settings, such as dentist, chiropractor, and optometrist offices (39.3%). Healthcare personnel who were younger, who had higher education, higher annual household income, a personal healthcare provider, and health insurance had higher Tdap vaccination coverage compared with reference groups. Tdap vaccination coverage among healthcare personnel in 21 states ranged from 30.6% in Mississippi to 65.9% in Washington. CONCLUSIONS: Improvement in Tdap vaccination among healthcare personnel is needed to potentially reduce opportunities for spread of pertussis in healthcare settings. On-site workplace vaccination, offering vaccines free of charge, and promoting vaccination may increase vaccination among healthcare personnel. PMID- 29174082 TI - Multiple reaction monitoring mass spectrometry to identify novel plasma protein biomarkers of treatment response in cystic fibrosis pulmonary exacerbations. AB - BACKGROUND: Systemic inflammation decreases with IV antibiotics during the treatment of CF pulmonary exacerbations (PEx). We used multiple reaction monitoring mass spectrometry and immunoassays to monitor blood proteins during PEx treatment to determine if early changes could be used to predict PEx outcomes following treatment. METHODS: Blood samples from 25 PEx (22 unique adults) were collected within 24h of admission, day 5, day 10, and at IV antibiotic completion. Ninety-two blood proteins involved in host immunity and inflammation were measured. RESULTS: Levels of several blood proteins changed from admission to end of IV antibiotics, most increasing with treatment. Early changes (admission to day 5) in fibrinogen levels had the strongest correlation with overall improvement in CFRSD-CRISS and FEV1% predicted by the end of treatment. CONCLUSIONS: Several plasma proteins changed significantly with IV antibiotics. Future studies will evaluate fibrinogen as an early biomarker of PEx treatment response in CF. PMID- 29174083 TI - Addition of an EGFP-tag to the N-terminal of influenza virus M1 protein impairs its ability to accumulate in ND10. AB - A previous report demonstrated that influenza virus infection induces accumulation of EGFP-tagged M1 protein (EGFP-M1) in the sub-nuclear domain ND10. Here, we show that the transfection of four viral protein (NP, PB2, PB1, PA) expression vectors and eight RNA segment expression vectors induced the formation of nuclear dots of EGFP-M1 as seen in virus infections. Omission of the segment 7 RNA expression vector, however, abolished the nuclear dots of EGFP-M1. This result suggests an essential role for authentic M1 protein and/or M2 protein, both of which are encoded in segment 7, in the formation of nuclear dots of EGFP M1. Co-expression of M1 protein but not M2 protein with EGFP-M1 induced the formation of nuclear dots of EGFP-M1. The dots co-localized with PML protein, which is an indicator of ND10. When only M1 protein was expressed, immunostaining of M1 protein clearly revealed the nuclear dots and their colocalization with PML protein. These results demonstrate that the accumulation in ND10 is an intrinsic characteristic of M1 protein and EGFP addition abolishes this characteristic. The addition of EGFP to M1 protein induced a defect in M1 protein. PMID- 29174085 TI - Resistance to first-line ART and a role for dolutegravir. PMID- 29174086 TI - Utility of Liquid Biopsy by Improved PNA-LNA PCR Clamp Method for Detecting EGFR Mutation at Initial Diagnosis of Non-Small-Cell Lung Cancer: Observational Study of 190 Consecutive Cases in Clinical Practice. AB - BACKGROUND: The clinical benefit of liquid biopsy for unselected patients at initial diagnosis has thus far been unclear. We aimed to evaluate the utility of liquid biopsy at initial diagnosis, as well as the efficacy of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) based on liquid biopsy results in clinical practice, using the improved peptide nucleic acid-locked nucleic acid (PNA-LNA) PCR clamp method. PATIENTS AND METHODS: We routinely performed liquid biopsy using the improved PNA-LNA PCR clamp method for all patients diagnosed with non-small-cell lung cancer (NSCLC) between June 2015 and October 2016. We retrospectively evaluated the reliability of liquid biopsy based either on clinical stage or between sensitizing EGFR mutation and T790M mutation, and the clinical benefit of EGFR-TKI based on the liquid biopsy results in practice. RESULTS: A total of 244 patients underwent liquid biopsies, with 168 patients tested at diagnosis and 22 tested for T790M after pretreatment of EGFR TKI. For detecting a sensitizing EGFR mutation, the sensitivity, specificity, positive predictive value, and negative predictive value were 72.7%, 100%, 100%, and 93.7% in the group with advanced-stage NSCLC and 0, 100%, not evaluable, and 70.5% in the group with early-stage NSCLC. The positive predictive value and negative predictive value for T790M were 33.3% and 55.6%, respectively. Fourteen patients in the liquid-positive group and 16 patients in the tissue-positive group received EGFR-TKI. The objective response rates of first- and second generation EGFR-TKI for the liquid-positive and tissue-positive groups were 90.0% and 90.9%, respectively. There was no significant difference in median progression-free survival between the liquid-positive and tissue-positive groups (P = .839). CONCLUSION: Patients with early-stage NSCLC should not be candidates for this liquid biopsy method. We recommend tissue biopsy as the preferred initial method of molecular analysis, with the exception of patients who are T790M positive or patients who are unable to tolerate invasive biopsy. PMID- 29174087 TI - Learning curve for transbronchial lung cryobiopsy in diffuse lung disease. AB - INTRODUCTION: Transbronchial lung cryobiopsy (TBLC) is increasingly used in the diagnosis of diffuse lung disease (DLD), but no data have yet been published on the learning curve associated with this technique. AIM: To evaluate diagnostic yield, lung tissue sample length and area, and procedure-related complications in a cohort of TBLC procedures to define the learning curve and threshold for proficiency. METHODS: Retrospective analysis of the first 100 TBLCs performed in different segments of the same lobe in patients with suspected DLD. We compared diagnostic yield, sample length and area, and complications between consecutive groups of patients. RESULTS: The overall diagnostic yield for TBLC was 82%. Median sample length was 5.4mm (IQR, 5-6) and median area was 19.5mm2 (IQR, 13.3 25). Pneumothorax was the most common complication (18%). On comparing the two groups of 50 consecutive patients, a significant difference was found for diagnostic yield (74% vs 90%; p=0.04), sample length (5.0mm [2.5-16] vs 6.0mm [4 12;] p<0.01) and area (17.5mm2 [6-42] vs 21.5mm2 [10-49]; p<0.01). Logarithm regression was applied to median diagnostic yield and sample length and area for groups of 10 consecutive patients to define the learning curve, which plateaued after approximately 70 procedures. CONCLUSIONS: Our findings suggest that proficiency in TBLC is achieved at approximately the 70th procedure; however they need to be validated in more series and cohorts. PMID- 29174084 TI - Cost-effectiveness of public-health policy options in the presence of pretreatment NNRTI drug resistance in sub-Saharan Africa: a modelling study. AB - BACKGROUND: There is concern over increasing prevalence of non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance in people initiating antiretroviral therapy (ART) in low-income and middle-income countries. We assessed the effectiveness and cost-effectiveness of alternative public health responses in countries in sub-Saharan Africa where the prevalence of pretreatment drug resistance to NNRTIs is high. METHODS: The HIV Synthesis Model is an individual based simulation model of sexual HIV transmission, progression, and the effect of ART in adults, which is based on extensive published data sources and considers specific drugs and resistance mutations. We used this model to generate multiple setting scenarios mimicking those in sub-Saharan Africa and considered the prevalence of pretreatment NNRTI drug resistance in 2017. We then compared effectiveness and cost-effectiveness of alternative policy options. We took a 20 year time horizon, used a cost effectiveness threshold of US$500 per DALY averted, and discounted DALYs and costs at 3% per year. FINDINGS: A transition to use of a dolutegravir as a first-line regimen in all new ART initiators is the option predicted to produce the most health benefits, resulting in a reduction of about 1 death per year per 100 people on ART over the next 20 years in a situation in which more than 10% of ART initiators have NNRTI resistance. The negative effect on population health of postponing the transition to dolutegravir increases substantially with higher prevalence of HIV drug resistance to NNRTI in ART initiators. Because of the reduced risk of resistance acquisition with dolutegravir-based regimens and reduced use of expensive second-line boosted protease inhibitor regimens, this policy option is also predicted to lead to a reduction of overall programme cost. INTERPRETATION: A future transition from first-line regimens containing efavirenz to regimens containing dolutegravir formulations in adult ART initiators is predicted to be effective and cost effective in low-income settings in sub-Saharan Africa at any prevalence of pre ART NNRTI resistance. The urgency of the transition will depend largely on the country-specific prevalence of NNRTI resistance. FUNDING: Bill & Melinda Gates Foundation, World Health Organization. PMID- 29174088 TI - Platelets are involved in in vitro swine granulosa cell luteinization and angiogenesis. AB - During corpus luteum formation, impressive biological events take place to guarantee the transition from original follicular to luteal cells and to support required massive angiogenesis. It has been demonstrated that these phenomena resemble those essential for wound healing. After ovulation, blood vessels release their content in the antral cavity and coagulation takes place. Involvement of platelets in corpus luteum growth has been hypothesized both in human and in rat. On this basis, using platelet lysate (PL), a blood derivative with a higher platelet concentration, we aimed to assess a potential involvement of platelets in swine granulosa cell luteinization and on new blood vessel growth. Our results demonstrate, for the first time in the swine, that platelets could be directly involved in granulosa cell physiological luteinization, since the treatment with PL shifted steroid production from estradiol 17beta to progesterone. Moreover, PL stimulated angiogenesis. Nitric oxide could be involved in these effects. These results are important to clarify complex intrafollicular molecular machinery. A better understanding of these mechanisms can be useful to develop more focused therapeutic strategies to contrast sow infertility. In addition, since the pig represents a model for translational studies, collected data could be of interest for human medicine because reproductive pathologies such as Polycystic Ovary Syndrome (PCOS) and endometriosis are often accompanied by platelet dysfunctions. PMID- 29174089 TI - Uncommon runs of homozygosity disclose homozygous missense mutations in two ciliopathy-related genes (SPAG17 and WDR35) in a patient with multiple brain and skeletal anomalies. AB - We describe a patient severely affected with multiple congenital anomalies, including brain malformations and skeletal dysplasia suggestive of cranioectodermal dysplasia (CED) ciliopathy, who unusually carries several homozygosity tracts involving homozygous missense mutations in SPAG17 (exon 8; c.1069G > C; p.Asp357His) and WDR35 (exon 13; c.1415G > A; p.Arg472Gln) as revealed by homozygosity mapping and next generation sequencing. SPAG17 is essential for the function and structure of motile cilia, while WDR35 belongs to the same intraflagellar transport (IFT) gene family whose protein products are part of functional IFT A and B complexes. Formerly, SPAG17 was related - through polymorphic variants - to an influence on individuals' height; more recently, Spag17-/- mice models were reported to present skeletal and bone defects, reduced mucociliary clearance, respiratory distress, and cerebral ventricular enlargement. Homozygous or compound heterozygous mutations in WDR35 have mainly been related to CED2 or short-rib thoracic dysplasia 7, with only three cases showing some brain anomalies. Given that our patient presents these clinical features and the close functional relationship between SPAG17 and WDR35, it is feasible that the combined effects from both mutations contribute to his phenotype. To our knowledge, this patient is the first to harbor a likely pathogenic homozygous mutation in both genes at the same time. Thus, the resulting complex phenotype of this patient illustrates the heterogeneity associated with ciliopathies and further expands the clinical and mutational spectrum of these diseases. Finally, we highlight the combined use of high throughput tools to diagnose and support the proper handling of this and other patients. PMID- 29174090 TI - Molecular cytogenetics characterization of seven small supernumerary marker chromosomes derived from chromosome 19: Genotype-phenotype correlation and review of the literature. AB - Only a few subjects carrying supernumerary marker chromosomes derived from 19 chromosome (sSMC(19)) have been described to date and for a small portion of them the genic content has been defined at the molecular level. We present seven new different sSMCs(19) identified in eight individuals, seven of whom unrelated. The presence of the sSMC is associated with a clinical phenotype in five subjects, while the other three carriers, two of whom related, are normal. All sSMCs(19) have been characterized by means of conventional and molecular cytogenetics. We compare the sSMCs(19) carriers with a clinical phenotype to already described patients with gains (sSMCs or microduplications) of overlapping genomic regions with the aim to deepen the pathogenicity of the encountered imbalances and to assess the role of the involved genes on the phenotype. The present work supports the correlation between the gain of some chromosome 19 critical regions and specific phenotypes. PMID- 29174091 TI - Pancreatic hemi-agenesis in MEN1: A clinical report. AB - We first describe a patient with multiple endocrine neoplasia type 1 (MEN1) and dorsal pancreatic hemi-agenesis. Previously, pancreas divisum has been reported in MEN1. Recent data in mice have elucidated the molecular mechanisms of pancreatic endoderm specification. Disinhibition of hedgehog signaling appears to be important in how Gata4 and Gata6 variants cause pancreatic agenesis. Disinhibition of hedgehog signaling has also been observed in Men1 knockout pancreatic islets. Although we cannot exclude a spurious association between dorsal pancreatic hemi-agenesis and MEN1 in our patient, we argue that developmental abnormalities of the pancreas may have to be considered as possibly related to the MEN1 phenotype.

AB - De novo monoallelic mutations in the GNB1 gene, encoding a beta subunit of heterotrimeric G proteins, cause a newly recognized disorder with the typical clinical picture of severe developmental delay/intellectual disability, hypotonia and extrapyramidal symptoms. We describe another case of the condition with manifestations of cutaneous mastocytosis associated with a novel do novo mutation GNB1NM_001282539.1: c.230G > T; p.(Gly77Val). We also present the detailed clinical and etiopathogenetic discussion on previously diagnosed patients as well as suggestions for the link of the mutation with skin disease. PMID- 29174092 TI - Rare copy number variants identified in prune belly syndrome. AB - Prune belly syndrome (PBS), also known as Eagle-Barrett syndrome, is a rare congenital disorder characterized by absence or hypoplasia of the abdominal wall musculature, urinary tract anomalies, and cryptorchidism in males. The etiology of PBS is largely unresolved, but genetic factors are implicated given its recurrence in families. We examined cases of PBS to identify novel pathogenic copy number variants (CNVs). A total of 34 cases (30 males and 4 females) with PBS identified from all live births in New York State (1998-2005) were genotyped using Illumina HumanOmni2.5 microarrays. CNVs were prioritized if they were absent from in-house controls, encompassed >=10 consecutive probes, were >=20 Kb in size, had <=20% overlap with common variants in population reference controls, and had <=20% overlap with any variant previously detected in other birth defect phenotypes screened in our laboratory. We identified 17 candidate autosomal CNVs; 10 cases each had one CNV and four cases each had two CNVs. The CNVs included a 158 Kb duplication at 4q22 that overlaps the BMPR1B gene; duplications of different sizes carried by two cases in the intron of STIM1 gene; a 67 Kb duplication 202 Kb downstream of the NOG gene, and a 1.34 Mb deletion including the MYOCD gene. The identified rare CNVs spanned genes involved in mesodermal, muscle, and urinary tract development and differentiation, which might help in elucidating the genetic contribution to PBS. We did not have parental DNA and cannot identify whether these CNVs were de novo or inherited. Further research on these CNVs, particularly BMP signaling is warranted to elucidate the pathogenesis of PBS. PMID- 29174094 TI - Missense mutation of TTC7A mimicking tricho-hepato-enteric (SD/THE) syndrome in a patient with very-early onset inflammatory bowel disease. AB - Tricho-hepato-enteric syndrome (SD/THE) and Multiple intestinal atresia with combined immune deficiency (MIA-CID) are autosomal recessive disorders that present immunological and gastrointestinal features. There are two different phenotypes of patients with TTC7A mutations: the severe form, caused by null mutations and leading to the classical MIA-CID; and the mild form, caused by missense mutations and leading to predominant features of VEO-IBD, less severe immunological involvement and hair abnormalities. We expand the knowledge about TTC7A deficiency, describing a patient with the mild phenotype of TTC7A deficiency but presenting overlapping features of SD/THE and MIA-CID: intestinal atresia and inflammatory bowel disease evocative of MIA-CID, but also dental abnormalities, huge forehead, liver abnormalities, autoimmune thyroiditis and hypogammaglobulinemia, evocative of SD/THE.

PMID- 29174096 TI - Surgical and Nonsurgical Management of Mallet Finger: A Systematic Review. AB - PURPOSE: The current literature describes multiple surgical and nonsurgical techniques for the management of mallet finger injuries, and there is no consensus on the indications for surgical treatment. The objective of this study was to determine, through a literature review, if any conclusions can be drawn concerning the indications for surgery in mallet finger injuries; the treatment outcomes of surgical versus nonsurgical management; the most effective methods of surgical and nonsurgical treatment; and the most common treatment complications of mallet finger injuries. METHODS: A systematic review of multiple databases was performed. English language clinical studies evaluating therapeutic interventions for mallet fingers that reported objective, standardized outcome measures were included. Basic science studies, cadaveric studies, conference abstracts, level V evidence studies, studies lacking statistical data, and tendinous injuries other than mallet fingers were excluded. Salvage procedures and studies evaluating exclusively chronic lesions were also excluded. RESULTS: Forty-four studies that reported clinical outcomes for the treatment of mallet finger injuries, 22 evaluating surgical treatments and 17 studies investigating nonsurgical treatments were included. The average distal interphalangeal joint extensor lag was 5.7 degrees after surgical treatment and 7.6 degrees after nonsurgical treatment. Complication rates of surgical and nonsurgical interventions were comparable (14.5% and 12.8%, respectively). Five studies directly compared the outcomes of surgical with nonsurgical management, with mixed results and recommendations. CONCLUSIONS: Both surgical and nonsurgical treatments of mallet finger injuries lead to excellent clinical outcomes. Insufficient evidence is available to determine when surgical intervention is indicated. Based on our literature review, it appears that these treatments are equivalent and should be individualized to the patient. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV. PMID- 29174097 TI - Effects of propofol on ventricular repolarization and incidence of malignant arrhythmias in adults. AB - BACKGROUND: Propofol is commonly used for procedural sedation in interventional electrophysiology. However, ventricular arrhythmias under Propofol have been reported. Our aim was to investigate ventricular repolarization and incidence of ventricular arrhythmias under Propofol infusion in adults with cardiac arrhythmias. METHODS: QRS, QTcB (Bazett), QTcFri (Fridericia), JTc, measurement of T peak to Tend time (Tp-e) at baseline and under Propofol infusion was performed in 235 patients. Screening for unexpected ventricular arrhythmias was performed in 1165 patients undergoing EP procedures under Propofol. RESULTS: A significant prolongation of Tp-e under Propofol infusion (79.7+/-17.3 vs. 86.4+/ 22.5ms, p<0.001) and of QTcFri (429.3+/-35.8 vs. 435.5+/-36.5, p=0.033) was detected. No significant change of the QTcB interval, JTc interval or QRS duration was observed. One case (0.09%) of ventricular fibrillation during rapid ventricular pacing under Propofol occurred. CONCLUSION: Although transmural dispersion of ventricular repolarisation is increased under Propofol, incidence of malignant ventricular arrhythmias is low. For evaluation of QT interval under Propofol, Fridericia's correction formula should be used rather than Bazett's formula. PMID- 29174098 TI - Which admission electrocardiographic parameter is more powerful predictor of no reflow in patients with acute anterior myocardial infarction who underwent primary percutaneous intervention? AB - BACKGROUND: Acute transmural ischemia due to left anterior descending artery (LAD) occlusion changes precordial R and Q wave durations owing to depressed intramyocardial activation. We investigated the prognostic value of sum of precordial Q wave duration/sum of precordial R wave duration ratio (Q/R) in patients with first acute anterior myocardial infarction (AAMI) treated with primary percutaneous coronary intervention (PPCI). METHODS: In this prospective analysis, we evaluated the no-reflow predictive value of Q/R on 403 patients with first AAMI. Patients were divided into two as no-reflow group (n=32) and control (n=371) group according to post-PPCI flow status. RESULTS: The patients in the no reflow group had significantly higher Q/R on admission electrocardiography (ECG) compared to patients in the control group (p<0.001). When admission ECG parameters were compared according to no-reflow prediction, Q/R was stronger than other well-accepted parameters. The best cut-off value of the Q/R to predict no reflow was 1.08 with 76% sensitivity and 73% specificity (AUC: 0.78; 95% CI: 0.72 0.83; p<0.001). CONCLUSION: In patients with first AAMI treated with PPCI, Q/R in admission ECG may have a role as an independent predictive marker of no-reflow.

AB - In patients experiencing an ST-elevation myocardial infarction (STEMI), rapid diagnosis and immediate access to reperfusion therapy leads to optimal clinical outcomes. The rate-limiting step in STEMI diagnosis is the availability and performance of a 12-lead ECG. Recent technology has provided access to a reliable means of obtaining an ECG reading through a smartphone application (app) that works with an attachment providing all 12-leads of a standard ECG system. The ST LEUIS study was designed to validate the smartphone ECG app and its ability to accurately assess the presence or absence of STEMI in patients presenting with chest pain compared with the gold standard 12-lead ECG. We aimed to support the diagnostic utility of smartphone technology to provide a timely diagnosis and treatment of STEMI. The study will take place over 12months at five institutions. Approximately 60 patients will be enrolled per institution, for a total recruitment of 300 patients. PMID- 29174100 TI - Cable Bacteria Take a New Breath Using Long-Distance Electricity. AB - Recently, a new group of multicellular microorganisms was discovered, called 'cable bacteria', which are capable of generating and mediating electrical currents across centimetre-scale distances. By transporting electrons from cell to cell, cable bacteria can harvest electron donors and electron acceptors that are widely separated in space, thus providing them with a competitive advantage for survival in aquatic sediments. The underlying process of long-distance electron transport challenges some long-held ideas about the energy metabolism of multicellular organisms and entails a whole new type of electrical cooperation between cells. This review summarizes the current knowledge about these intriguing multicellular bacteria. PMID- 29174101 TI - Antibacterial Toxins: Gram-Positive Bacteria Strike Back! AB - Bacteria live in communities where strains compete with each other by deploying an arsenal of antibacterial toxins. While the past decade revealed the vast array of antibacterial toxins secreted by Gram-negative bacteria, several recent studies have begun to uncover the ability of Gram-positive bacteria to battle with their own weapons.

AB - We retrospectively audited the records of 708 patients who presented with the diagnosis of fractured mandible between January 2009 and July 2013 at the Queen Elizabeth Hospital, Birmingham. We assessed the different factors that may have altered their outcomes, and found that delay before definitive fixation caused no harm in either the short or the long term. PMID- 29174104 TI - Reconstruction of intraoral defects after resection of cancer with two types of submental artery perforator flaps. AB - The submental island flap is a common choice for reconstruction of intraoral defects. To obtain a thinner, more pliable flap and get a better oncological result, the submental artery perforator flap has been proposed, and to assess its feasibility for closure of defects after resection of cancers of the oral cavity we studied 20 patients, each of whom was treated in this way. All the flaps were classified into those with septocutaneous perforators (n=16) and those with musculocutaneous perforators (n=4), and the main veins that drained the flaps were two submental veins (n=17). There were two patterns of venous drainage: in pattern 1 (n=9) the external jugular vein provided the primary venous drainage, and in pattern 2, the submental veins drained mainly into the facial vein, the common facial vein, and the internal jugular (n=10). In one patient the submental veins bypassed the facial vein to drain into the internal jugular. Eighteen of the 20 patients had no postoperative complications. The remaining two developed mild venous congestion of the flaps, which was resolved with conservative management and no skin loss. No local or regional recurrence was detected after a mean (range) follow-up of 21 (4-35) months. This is a simple, reliable flap that can be used for the reconstruction of intraoral defects after resections for cancer, but its oncological outcome still requires proof in long-term, large scale, clinical trials. PMID- 29174105 TI - Clinical outcomes of dental implants after use of tenting for bony augmentation: a systematic review. AB - The reconstruction of severely atrophic ridges is often challenging and complicated. We searched the Medline, Embase, and Cochrane databases for articles up to October 2015 that reported the success of all types of tenting for bony regeneration. We extracted data on the size and site of the defect, the number of patients, vertical and horizontal augmentation, survival of dental implants, and complications. Thirteen studies were included, which yielded data on 423 patients with 1111 dental implants. Follow-up periods were more than five years, severely resorbed mandibles were augmented vertically by up to 10mm, and the survival rate of the implants was over 97%. The mean (SD) gain in horizontal width by screw tenting was 3 (0.63)mm, and over 97.6% of dental implants in cortical tenting investigations survived. A tenting approach may reduce the need for large autogenous bone grafts in the reconstruction of severely atrophic ridges and local bony defects, and improves the survival of implants. PMID- 29174106 TI - A rapid qualitative assessment of oral cholera vaccine anticipated acceptability in a context of resistance towards cholera intervention in Nampula, Mozambique. AB - INTRODUCTION: While planning an immunization campaign in settings where public health interventions are subject to politically motivated resistance, designing context-based social mobilization strategies is critical to ensure community acceptability. In preparation for an Oral Cholera Vaccine campaign implemented in Nampula, Mozambique, in November 2016, we assessed potential barriers and levers for vaccine acceptability. METHODS: Questionnaires, in-depth interviews, and focus group discussions, as well as observations, were conducted before the campaign. The participants included central and district level government informants (national immunization program, logistics officers, public health directors, and others), community leaders and representatives, and community members. RESULTS: During previous well chlorination interventions, some government representatives and health agents were attacked, because they were believed to be responsible for spreading cholera instead of purifying the wells. Politically motivated resistance to cholera interventions resurfaced when an OCV campaign was considered. Respondents also reported vaccine hesitancy related to experiences of problems during school-based vaccine introduction, rumors related to vaccine safety, and negative experiences following routine childhood immunization. Despite major suspicions associated with the OCV campaign, respondents' perceived vulnerability to cholera and its perceived severity seem to override potential anticipated OCV vaccine hesitancy. DISCUSSION: Potential hesitancy towards the OCV campaign is grounded in global insecurity, social disequilibrium, and perceived institutional negligence, which reinforces a representation of estrangement from the central government, triggering suspicions on its intentions in implementing the OCV campaign. Recommendations include a strong involvement of community leaders, which is important for successful social mobilization; representatives of different political parties should be equally involved in social mobilization efforts, before and during campaigns; and public health officials should promote other planned interventions to mitigate the lack of trust associated with perceived institutional negligence. Successful past initiatives include public intake of purified water or newly introduced medication by social mobilizers, teachers or credible leaders. PMID- 29174107 TI - Assessing the safety of hepatitis B vaccination during pregnancy in the Vaccine Adverse Event Reporting System (VAERS), 1990-2016. AB - BACKGROUND: The safety of hepatitis B vaccination during pregnancy has not been well studied. OBJECTIVE: We characterized adverse events (AEs) after hepatitis B vaccination of pregnant women reported to the Vaccine Adverse Event Reporting System (VAERS), a spontaneous reporting surveillance system. METHODS: We searched VAERS for AEs reports involving pregnant women who received hepatitis B vaccine from January 1, 1990-June 30, 2016. All reports and available medical records were reviewed by physicians. Observed AEs were compared to expected AEs and known rates of pregnancy outcomes to assess for any unexpected safety concern. RESULTS: We found 192 reports involving pregnant women following hepatitis B vaccination of which 110 (57.3%) described AEs; 12 (6.3%) were classified as serious; one newborn death was identified in a severely premature delivery, and there were no maternal deaths. Eighty-two (42.7%) reports did not describe any AEs. Among pregnancies for which gestational age was reported, most women were vaccinated during the first trimester, 86/115 (74.7%). Among reports describing an AE, the most common pregnancy-specific outcomes included spontaneous abortion in 23 reports, preterm delivery in 7 reports, and elective termination in 5 reports. The most common non-pregnancy specific outcomes were general disorders and administration site conditions, such as injection site and systemic reactions, in 21 reports. Among 22 reports describing an AE among infants born to women vaccinated during pregnancy, 5 described major birth defects each affecting different organ systems. CONCLUSION: Our analysis of VAERS reports involving hepatitis B vaccination during pregnancy did not identify any new or unexpected safety concerns. PMID- 29174108 TI - Association of prior HPV vaccination with reduced preterm birth: A population based study. AB - BACKGROUND: Emerging evidence suggests that HPV infection is associated with negative pregnancy outcomes such as preterm birth (PTB), and pre-eclampsia. We aimed to determine if prior HPV vaccination reduced adverse pregnancy outcomes. METHODS: A New Zealand population-based retrospective study linking first pregnancy outcome data (2008-2014 n = 35,646) with prior quadrivalent HPV vaccination status. Primary outcomes were likelihood (odds ratios, ORs) of PTB, pre-eclampsia, and stillbirth. Exposure groups were based on HPV vaccination. Adjusted ORs were calculated for each outcome, controlling for mother's age at delivery, ethnicity, socioeconomic status, health board region at time of delivery, and body mass index and smoking status at time of registration with maternity care provider. RESULTS: Mother's mean age at delivery was 19 (SD 2.1) years. Of 34,994 the pregnancies included in the final study analyses 62.3% of women were unvaccinated, 11.0% vaccinated with one or two doses and 27.7% vaccinated with three doses prior to pregnancy. PTB (OR: 0.87; CI 0.78, 0.96)) was significantly lower for women who previously received the HPV vaccine. A dose response effect was found with each successive dose received decreasing the likelihood of PTB. No associations between the vaccinated and unvaccinated groups were shown for pre-eclampsia or stillbirth. CONCLUSIONS: Prior receipt of the quadrivalent HPV vaccine was associated with a significant reduction in PTB (13%); suggesting that HPV vaccination may be effective in reducing PTB. The potential global public health impact is considerable and there is urgency to undertake further research to replicate and explore these findings. PMID- 29174109 TI - Comparative immunogenicity and safety of human papillomavirus (HPV)-16/18 AS04 adjuvanted vaccine and 4vHPV vaccine administered according to two- or three-dose schedules in girls aged 9-14 years: Results to month 36 from a randomized trial. AB - : This observer-blind study (clinicaltrials.gov NCT01462357) compared the immunogenicity and safety of two doses (2D) of the HPV-16/18 AS04-adjuvanted vaccine (2D of AS04-HPV-16/18) vs. two or three doses of the 4vHPV vaccine [2D or 3D of 4vHPV] in 1075 healthy girls aged 9-14 years. Girls were randomized (1:1:1) to receive 2D of AS04-HPV-16/18 at months (M) 0, 6 (N = 359), 2D of 4vHPV at M0, 6 (N = 358) or 3D of 4vHPV at M0, 2, 6 (N = 358). 351, 339 and 346 girls, respectively, returned for the concluding visit at M36. Superiority was demonstrated at M7 and M12; comparison of the immune response to both vaccine antigens was made between 2D of AS04-HPV-16/18 and 2D or 3D of 4vHPV at subsequent time points in the according-to-protocol immunogenicity cohort (ATP-I; N = 958 at M36) and the total vaccinated cohort (TVC: N = 1036 at M36). HPV-16/18 specific T-cell- and B-cell-mediated immune responses and safety were also investigated. At M36, anti-HPV-16/18 ELISA responses in the 2D AS04-HPV-16/18 group remained superior to those of the 2D and 3D 4vHPV groups. In the M36 TVC, geometric mean titers were 2.78-fold (HPV-16) and 6.84-fold (HPV-18) higher for 2D of AS04-HPV-16/18 vs. 2D of 4vHPV and 2.3-fold (HPV-16) and 4.14-fold (HPV-18) higher vs. 3D of 4vHPV. Results were confirmed by vaccine pseudovirion-based neutralisation assay. Numbers of circulating CD4+ T cells and B cells appeared similar across groups. Safety was in line with the known safety profiles of both vaccines. In conclusion, superior HPV-16/18 antibody responses were elicited by 2D of the AS04-HPV-16/18 compared with 2D or 3D of the 4vHPV vaccine in girls aged 9-14 years.

AB - Sweet solutions are one of the most widely used nonpharmacologic analgesics used for newborns. They alleviate mild to moderate pain induced by painful procedures. They are used daily in neonatal intensive care units before a venepuncture or a heel stick, especially for a blood-sugar measurement. It is agreed that analgesic sweet solutions do not modify glycemia results. This nevertheless remains a recurrent question that the present review attempts to answer. PMID- 29174111 TI - [Pseudomonas aeruginosa in post-piercing perichondritis: Two case reports]. AB - The frequency of body piercing has increased in France over the past few years, particularly among teenagers. Piercing can be performed at different sites on the body, especially in the cartilage of the ears. We relate two cases of Pseudomonas aeruginosa chondritis. A 10-year retrospective study at the Marseille University Hospital found no additional pediatric cases. These infectious complications can sometimes be necrotizing. It is therefore important to inform the medical staff on the hygiene measures that need to be respected and the patients on the treatment to follow after the piercing as well as the signs to watch for, possibly indicating chondritis. The esthetic consequences depend on early diagnosis. PMID- 29174112 TI - Mechanism of Rhinella icterica (Spix, 1824) toad poisoning using in vitro neurobiological preparations. AB - The biological activity of Rhinella icterica toxic secretion (RITS) was evaluated on chick neuromuscular junctions, rat hearts tissue and mice hippocampal slices. At chick biventer cervicis preparation, RITS (5, 10 and 20MUg/mL) produced a concentration-independent irreversible neuromuscular blockade, which was preceded by a transitory increase of muscle twitch tension with the lowest concentration, in 120min recordings. In this set of experiments, RITS incubation partially prevented the curare neuromuscular blockade. The assessment of chick biventer cervicis muscle acetylcholinesterase (AChE) in the presence of RITS showed a significant inhibition of the enzyme, similarly to neostigmine. The incubation of muscles with digoxin or ouabain mimicked the poison activity by increasing the amplitude of the twitches followed by a progressive depression of the muscle strength. In addition, RITS demonstrated a digitalic-like activity, by inhibiting significantly the cardiac Na+, K+-ATPase. When the central nervous system was accessed, RITS induced an increase in the cell viability, in the lowest concentration. In addition, the poison protected slices subject to oxygen/glucose deprivation. Altogether, these data indicate that the poisonous extract of R. icterica is able to interfere with peripheral and central neurotransmission, probably due to a direct interaction with AChE, calcium channels and Na+, K+ ATPase. A further investigation upon the poison toxic components will unveil the components involved in such a pharmacological activity and the potential biotechnological application of this poison. PMID- 29174113 TI - Ghrelin protects retinal ganglion cells against rotenone via inhibiting apoptosis, restoring mitochondrial function, and activating AKT-mTOR signaling. AB - Ghrelin, a 28-amino acid peptide hormone, has protective effects on neuronal cells. The present study aimed to examine the neuroprotective effects of ghrelin on the rat retinal ganglion cells in the rotenone-induced in vitro model of Parkinson's disease (PD). Cell viability and cell apoptosis were determined by MTT assay and flow cytometry, respectively. Mitochondrial functions were detected by mitochondrial complex I activity assay and mitochondrial membrane potential (MMP) assay. The mRNA and protein expression levels were determined by qRT-PCR and western blot, respectively. Rotenone significantly suppressed cell viability and increased cell apoptosis, also decreased the mitochondrial complex I activity as well as MMP in rat retinal ganglion cell line (RGC-5). Growth hormone secretagogue receptor (Ghsr) siRNA transfection significantly suppressed the expression of Ghsr in RGC-5 cells. Ghrelin treatment attenuated the effects of rotenone-induced changes in cell viability, cell apoptosis and mitochondrial functions in RGC-5 cells. Post-transcriptional suppression by Ghsr siRNA transfection and treatment with GHS-R antagonist, YIL781, both significantly attenuated the effects of ghrelin in RGC-5 cells. Rotenone decreased the protein levels of Bcl-2 and increased the protein levels of Bax, cleaved caspase-3 and cleaved caspase-9, and this effect was reversed by ghrelin treatment. Ghrelin also prevented the inhibitory effects of rotenone on the AKT-mTOR signaling. The effects of ghrelin on the rotenone-induced changes in apoptosis-related protein levels and AKT-mTOR signaling were attenuated by Ghsr siRNA transfection and treatment with YIL781 in the RGC-5 cells. In addition, both rapamycin and AKT inhibitor IV pre-treatment significantly attenuated the effects of ghrelin on rotenone-induced changes in cell viability and cell apoptosis. In conclusion, ghrelin by acting on the GSH-R to protect rat retinal ganglion cells against rotenone via inhibiting apoptosis and restore mitochondrial functions in RGC-5 cells, and this effect was partially associated with the AKT-mTOR signaling pathway in RGC-5 cells. PMID- 29174114 TI - The mechanism of skin lipids influencing skin status. AB - Skin lipids, compose of sebocyte-, keratinocyte-, and microbe- derived lipids, dramatically influence skin status by different mechanisms. (I) Physical chemistry function: They are "mortar" to establish the physico-chemical barrier function of skin; (II) Biochemistry function: They function as signals in the complex signaling network originating at the epidermal level; (III) Microecology function: Sebocyte- and keratinocyte-derived lipids vary the composition of microbial skin flora, and microorganisms metabolize them to produce lipids as signal starting signaling transduction. Importantly, further research needs lipidiomics, more powerful analytical ability and high-throughput manner, to identify skin lipid components into individual species. The validation of lipid structure and function to research the process that lipid species involved in. Additional, the integration of lipidomics data with other omics strategies can develop the power to study the mechanism of skin lipids influencing skin status. PMID- 29174115 TI - Modeling clinical efficacy of the S1P receptor modulator ponesimod in psoriasis. AB - BACKGROUND: Ponesimod is currently the only S1P receptor modulator studied in psoriasis. In a dose-finding study, the active doses showed similar efficacy. OBJECTIVE: Prediction of efficacy at lower doses to aid clinical phase 3 planning with respect to dose selection, duration of treatment, and patient inclusion criteria based on pharma-co-kinetic/pharmacodynamic (PK/PD) modeling and simulation. METHODS: The dose-finding study treated 326 patients (67 on placebo, 126 on 20mg, and 133 on 40mg) over 16 weeks. PK/PD modeling of steady-state trough concentrations and longitudinal PASI scores was employed to characterize data and simulate scenarios. RESULTS: PASI score continually decreased with time on ponesimod treatment, reaching a plateau at 16 weeks. Absolute and relative (percent) PASI score change was larger in patients with higher PASI score at baseline. Doses below 10mg were predicted to show lower efficacy than doses of 10mg and higher. CONCLUSION: Concentration-response modeling was able to predict the efficacy of doses that were not studied. In psoriasis patients, a dose of 10mg (not administered in the study) was predicted to show efficacy similar to 20mg. Disease status (PASI score at baseline) as study inclusion criterion has pronounced influence on study outcome. PMID- 29174116 TI - Hardening of particle/oil/water suspensions due to capillary bridges: Experimental yield stress and theoretical interpretation. AB - Suspensions of colloid particles possess the remarkable property to solidify upon the addition of minimal amount of a second liquid that preferentially wets the particles. The hardening is due to the formation of capillary bridges (pendular rings), which connect the particles. Here, we review works on the mechanical properties of such suspensions and related works on the capillary-bridge force, and present new rheological data for the weakly studied concentration range 30-55 vol% particles. The mechanical strength of the solidified capillary suspensions, characterized by the yield stress Y, is measured at the elastic limit for various volume fractions of the particles and the preferentially wetting liquid. A quantitative theoretical model is developed, which relates Y with the maximum of the capillary-bridge force, projected on the shear plane. A semi-empirical expression for the mean number of capillary bridges per particle is proposed. The model agrees very well with the experimental data and gives a quantitative description of the yield stress, which increases with the rise of interfacial tension and with the volume fractions of particles and capillary bridges, but decreases with the rise of particle radius and contact angle. The quantitative description of capillary force is based on the exact theory and numerical calculation of the capillary bridge profile at various bridge volumes and contact angles. An analytical formula for Y is also derived. The comparison of the theoretical and experimental strain at the elastic limit reveals that the fluidization of the capillary suspension takes place only in a deformation zone of thickness up to several hundred particle diameters, which is adjacent to the rheometer's mobile plate. The reported experimental results refer to water continuous suspension with hydrophobic particles and oily capillary bridges. The comparison of data for bridges from soybean oil and hexadecane surprisingly indicate that the yield strength is greater for the suspension with soybean oil despite its lower interfacial tension against water. The result can be explained with the different contact angles of the two oils in agreement with the theoretical predictions. The results could contribute for a better understanding, quantitative prediction and control of the mechanical properties of three-phase capillary suspensions solid/liquid/liquid. PMID- 29174117 TI - RS 10767664 gene variant in Brain Derived Neurotrophic Factor (BDNF) affect metabolic changes and insulin resistance after a standard hypocaloric diet. AB - BACKGROUND: Role of BDNF variants on change in body weight and cardiovascular risk factors after weight loss remains unclear in obese patients. OBJECTIVE: Our aim was to analyze the effects of rs10767664 BDNF gene polymorphism on body weight, cardiovascular risk factors and serum adipokine levels after a standard hypocaloric diet in obese subjects. DESIGN: A Caucasian population of 80 obese patients was analyzed before and after 3months on a standard hypocaloric diet. RESULTS: Fifty patients (62.5%) had the genotype AA and 30 (37.5%) subjects had the next genotypes; AT (25 patients, 31.3%) or TT (5 study subjects, 6.3%) (second group). In non T allele carriers, the decreases in weight-3.4+/-2.9kg (T allele group -1.7+/-2.0kg:p=0.01), BMI -1.5+/-0.2kg (T allele group -1.2+/ 0.5kg:p=0.02), fat mass-2.3+/-1.1kg (T allele group -1.7+/-0.9kg:p=0.009), waist circumference-3.8+/-2.4cm (T allele group -2.1+/-3.1cm:p=0.008), triglycerides 13.2+/-7.5mg/dl (T allele group +2.8+/-1.2mg/dl:p=0.02), insulin -2.1+/-1.9mUI/L (T allele group -0.3+/-1.0mUI/L:p=0.01), HOMA-IR -0.9+/-0.4 (T allele group 0.1+/-0.8:p=0.01) and leptin -10.1+/-9.5ng/dl (T allele group -3.1+/ 0.2ng/dl:p=0.01) were higher than T allele carriers. CONCLUSION: rs10767664 variant of BDNF gene modify anthropometric and biochemical changes after weight loss with a hypocaloric diet. PMID- 29174118 TI - Poor performance of clinical prediction models: the harm of commonly applied methods. AB - OBJECTIVE: To evaluate limitations of common statistical modeling approaches in deriving clinical prediction models and explore alternative strategies. STUDY DESIGN AND SETTING: A previously published model predicted the likelihood of having a mutation in germline DNA mismatch repair genes at the time of diagnosis of colorectal cancer. This model was based on a cohort where 38 mutations were found among 870 participants, with validation in an independent cohort with 35 mutations. The modeling strategy included stepwise selection of predictors from a pool of over 37 candidate predictors and dichotomization of continuous predictors. We simulated this strategy in small subsets of a large contemporary cohort (2,051 mutations among 19,866 participants) and made comparisons to other modeling approaches. All models were evaluated according to bias and discriminative ability (concordance index, c) in independent data. RESULTS: We found over 50% bias for five of six originally selected predictors, unstable model specification, and poor performance at validation (median c = 0.74). A small validation sample hampered stable assessment of performance. Model prespecification based on external knowledge and using continuous predictors led to better performance (c = 0.836 and c = 0.852 with 38 and 2,051 events respectively). CONCLUSION: Prediction models perform poorly if based on small numbers of events and developed with common but suboptimal statistical approaches. Alternative modeling strategies to best exploit available predictive information need wider implementation, with collaborative research to increase sample sizes. PMID- 29174119 TI - Engaging the Front Line: Tapping into Hospital-Wide Quality and Safety Initiatives. AB - Healthcare increasingly is moving from volume- to value-based care, with an emphasis on linking a larger percentage of payments to the quality of care provided. There is a renewed interest in designing a focused, strategic approach to quality and safety education and engagement of trainees in hospital-wide quality, safety, and patient experience initiatives. Hospitals, trainees, and patients benefit as a result of engaging frontline learners in these activities. Hospitals can leverage the intelligence from the front line to contribute to improved hospital safety, increased employee and patient engagement, and better identification of vulnerable areas of safety risks. Trainees benefit from increased engagement by acquiring fundamentals in quality and safety; are able to satisfy Clinical Learning Environment Review recommendations; have an opportunity to practice a number of skill sets (leadership, communication, collaboration); and complete quality and safety hands-on projects. Patients benefit from a more engaged work force, safer environment for their healthcare, and an improved overall experience. In this article, the current state of the Johns Hopkins Department of Anesthesiology and Critical Care Medicine's efforts to engage its front line in quality, safety, and patient experience initiatives that are in evolutionary phases of implementation is presented. Evolutionary concepts relate to the Johns Hopkins Health System and the aim of its training program to continuously improve and innovate.

AB - OBJECTIVE: Although increasing evidence in lung transplantation (LTx) suggests that intraoperative management could influence outcomes, there are no guidelines available regarding intraoperative management of LTx. The overall goal of the study was to assess geographic and center volume-specific clinical practices in perioperative management. DESIGN: Prospective data analysis. SETTING: Online survey from a single-center university hospital. PARTICIPANTS: European and non European LTx centers. INTERVENTIONS: An online survey was sent to 176 centers currently performing LTx procedures. It covered organizational data, general anesthesia considerations, fluid therapy and coagulation, antioxidant and anti inflammatory therapies, and ventilation strategies. MEASUREMENTS AND MAIN RESULTS: The response rates were 57.5% (n = 42) from European and 32% (n = 33) from non-European countries. Significant differences between European and non European countries were use of volatile hypnotics (p = 0.016), use of sufentanil (p < 0.001), inotropic agents (p = 0.001) and colloid infusion (p < 0.001), use of calibrated pulse contour analysis (p = 0.004), use of intraoperative traditional laboratory-based coagulation tests (p = 0.001) and platelet function analysis (p = 0.005), and use of higher peak inspiratory pressure (p = 0.009). Center volume-specific differences were use of fentanyl (p = 0.03) and the use of higher peak inspiratory pressure (p = 0.005) for ventilation. Induction of anesthesia and use of advanced hemodynamic monitoring, therapy for pulmonary hypertension, antioxidant and anti-inflammatory therapies, and ventilation strategies were not different among the centers. CONCLUSIONS: This survey demonstrated for the first time statistically significant differences among European and non-European centers and among low- versus high-volume centers regarding intraoperative management during LTx. These observations will be of some guidance for the LTx community and may trigger more extensive studies.

PMID- 29174128 TI - Intrauterine insemination with ovarian stimulation versus expectant management for unexplained infertility (TUI): a pragmatic, open-label, randomised, controlled, two-centre trial. AB - BACKGROUND: Women with unexplained infertility are often offered intrauterine insemination (IUI) with ovarian stimulation as an alternative to in-vitro fertilisation (IVF). However, little evidence exists that IUI is an effective treatment. In 2013, the UK National Institute for Health and Care Excellence recommended that IUI should not be routinely offered for couples with unexplained infertility. METHODS: For this pragmatic, open-label, randomised, controlled, two centre study, we enrolled women attending two fertility clinics in New Zealand with unexplained infertility and an unfavourable prognosis of natural conception. Participants were randomly assigned (1:1) using a computer-generated randomisation sequence, prepared by an independent statistician, to either three cycles of IUI with ovarian stimulation (with either oral clomifene citrate [50 150 mg, days 2-6] or oral letrozole [2.5-7.5 mg, days 2-6], with choice of ovarian stimulation made by the clinic) or three cycles of expectant management (couples advised to be sexually active around the likely time of ovulation and provided with a diary to record the first day of each menstrual cycle and dates of sexual activity) in blocks of four, six, and ten, without stratification. The participating couple and the clinicians were informed of treatment allocation. The primary outcome was cumulative livebirth rate in the intention-to-treat population. The safety analyses were done in the intention-to-treat population. This study was prospectively registered with the Australian and New Zealand Clinical Trials Register, number ACTRN12612001025820. FINDINGS: Between March 12, 2013, and May 12, 2016, we randomly assigned 101 women to IUI with ovarian stimulation and 100 to expectant management, all of whom were included in the primary efficacy analysis and safety analyses. Women assigned to IUI had a higher cumulative livebirth rate than women assigned to expectant management (31 [31%] livebirths among 101 women vs nine [9%] livebirths among 100 women; risk ratio [RR] 3.41, 95% CI 1.71-6.79; p=0.0003). Of 31 livebirths in the IUI group, 23 resulted from IUI cycles and eight were conceived without assistance before or between IUI cycles. Of nine livebirths in the expectant management group, one patient was pregnant from IUI with ovarian stimulation at study entry and one had received off-protocol treatment (IVF). Two sets of twins were born, both in the IUI group (one from a cancelled cycle for over-response). INTERPRETATION: IUI with ovarian stimulation is a safe and effective treatment for women with unexplained infertility and an unfavourable prognosis for natural conception.

PMID- 29174131 TI - Phase 1b/2a Trial of the Superoxide Dismutase Mimetic GC4419 to Reduce Chemoradiotherapy-Induced Oral Mucositis in Patients With Oral Cavity or Oropharyngeal Carcinoma. AB - PURPOSE: To assess the safety of the superoxide dismutase mimetic GC4419 in combination with radiation and concurrent cisplatin for patients with oral cavity or oropharyngeal cancer (OCC) and to assess the potential of GC4419 to reduce severe oral mucositis (OM). PATIENTS AND METHODS: Patients with locally advanced OCC treated with definitive or postoperative intensity modulated radiation therapy (IMRT) plus cisplatin received GC4419 by 60-minute intravenous infusion, ending <60 minutes before IMRT, Monday through Friday for 3 to 7 weeks, in a dose and duration escalation study. Oral mucositis was assessed twice weekly during and weekly after IMRT. RESULTS: A total of 46 patients received GC4419 in 11 separate dosing and duration cohorts: dose escalation occurred in 5 cohorts receiving 15 to 112 mg/d over 3 weeks (n=20), duration escalation in 3 cohorts receiving 112 mg/d over 4 to 6 weeks (n=12), and then 3 additional cohorts receiving 30 or 90 mg/d over 6 to 7 weeks (n=14). A maximum tolerated dose was not reached. One dose-limiting toxicity (grade 3 gastroenteritis and vomiting with hyponatremia) occurred in each of 2 separate cohorts at 112 mg. Nausea/vomiting and facial paresthesia during infusion seemed to be GC4419 dose related. Severe OM occurred through 60 Gy in 4 of 14 patients (29%) dosed for 6 to 7 weeks, with median duration of only 2.5 days. CONCLUSIONS: The safety of GC4419 concurrently with chemoradiation for OCC was acceptable. Toxicities included nausea/vomiting and paresthesia. Doses of 30 and 90 mg/d administered for 7 weeks were selected for further study. In an exploratory analysis, severe OM seemed less frequent and briefer than expected.

AB - In this study, for the first time, a magnetic dispersive solid phase extraction method using an easy-accessible, cheap, and efficient magnetic sorbent (toner powder) combined with dispersive liquid-liquid microextraction has been developed for the extraction and preconcentration of some widely used pesticides (diazinon, ametryn, chlorpyrifos, penconazole, oxadiazon, diniconazole, and fenazaquin) from fruit juices prior to their determination by gas chromatography-flame ionization detection. In this method, the magnetic sorbent is mixed with an appropriate dispersive solvent (methanol-water, 80:20, v/v) and then injected into an aqueous sample containing the analytes. By this action the analytes are rapidly adsorbed on the sorbent by binding to its carbon. The sorbent particles are isolated from the aqueous solution in the presence of an external magnetic field. Then an appropriate organic solvent (acetone) is used to desorb the analytes from the sorbent. Finally, the obtained supernatant is mixed with an extraction solvent and injected into deionized water in order to achieve high enrichment factors and sensitivity. Several significant factors affecting the performance of the introduced method were investigated and optimized. Under the optimum experimental conditions, the extraction recoveries of the proposed method for the selected analytes ranged from 49-75%. The relative standard deviations were <=7% for intra (n = 6) and inter-day (n = 4) precisions at a concentration of 10 MUg L-1 of each analyte. The limits of detection were in the range of 0.15-0.36 MUg L-1. Finally, the applicability of the proposed method was evaluated by analysis of the selected analytes in some fruit juices. PMID- 29174133 TI - Optimization for quick, easy, cheap, effective, rugged and safe extraction of mycotoxins and veterinary drugs by response surface methodology for application to egg and milk. AB - A multiclass method was proposed for the simultaneous determination of various classes of veterinary drugs (n = 65), mycotoxins and metabolites (n = 39) in egg and milk by ultra-high performance liquid chromatography-tandem mass spectrometry. The contaminants were extracted by QuEChERS-based strategy including salt-out partitioning and dispersive solid-phase extraction for cleanup further. With the aim of maximizing throughput and extraction efficiency, Plackett-Burman design was employed initially for screening significant variables. And response surface methodology based on central composite design was conducted to achieve optimal conditions in details: 3.35% (v/v) of formic acid in acetonitrile, 1.2 g of NaCl, 0.5 g of anhydrous NaAc, 300 mg of C18 and 140 mg of primary secondary amine. Satisfactory analytical characteristics in validation, in aspects of accuracy (70%-105% for mycotoxins and quinolones, 55%-80% for sulphonamides and 40%-105% for other veterinary drugs), precision (inter-day RSDs < 14%) and sensitivity (LOQs ranged from 0.01 MUg/kg to 31 MUg/kg), were achieved under the optimized conditions. The matrix effects were evaluated and compensated by the use of matrix-matched calibration curves (R2 > 0.987). In practice, 45 eggs and 30 milk samples were investigated by the established method, of which positive finding aflatoxin in milk and sterigmatocystin in eggs. PMID- 29174134 TI - Design of two-column batch-to-batch recirculation to enhance performance in ion exchange chromatography. AB - Preparative liquid chromatography is a separation technique widely used in the manufacturing of fine chemicals and pharmaceuticals. A major drawback of traditional single-column batch chromatography step is the trade-off between product purity and process performance. Recirculation of impure product can be utilized to make the trade-off more favorable. The aim of the present study was to investigate the usage of a two-column batch-to-batch recirculation process step to increase the performance compared to single-column batch chromatography at a high purity requirement. The separation of a ternary protein mixture on ion exchange chromatography columns was used to evaluate the proposed process. The investigation used modelling and simulation of the process step, experimental validation and optimization of the simulated process. In the presented case the yield increases from 45.4% to 93.6% and the productivity increases 3.4 times compared to the performance of a batch run for a nominal case. A rapid concentration build-up product can be seen during the first cycles, before the process reaches a cyclic steady-state with reoccurring concentration profiles. The optimization of the simulation model predicts that the recirculated salt can be used as a flying start of the elution, which would enhance the process performance. The proposed process is more complex than a batch process, but may improve the separation performance, especially while operating at cyclic steady state. The recirculation of impure fractions reduces the product losses and ensures separation of product to a high degree of purity.

AB - Gradient operation of a simulated moving bed (SMB) can improve the separation and purification performance by adjusting adsorption strength in each individual zone according to its functional role. The feasibility of an internal temperature gradient (ITG) established by a difference between feed and desorbent temperatures for binary separation of ketoprofen enantiomers was investigated based on simultaneous optimization of purity and productivity of S-ketoprofen, the preferentially adsorbed species and desired product. ITG operation with a temperature difference of 20K has a unit productivity higher than isothermal mode by about 20%. Due to the combined effects of temperature transition and downstream dilution, concentration profile may exhibit a remarkable peak and a pattern of two-step drop in the temperature descending and ascending areas, respectively. Both areas, if properly located under optimal conditions, are favorable for unit productivity, which cannot be predicted by the direct use of triangle theory and average Henry's constants. Modifications of the SMB operations to reduce solvent consumption were also discussed based on analyses of parametric sensitivity and internal concentration profiles. PMID- 29174136 TI - Mixed functional monomers-based monolithic adsorbent for the effective extraction of sulfonylurea herbicides in water and soil samples. AB - Effective extraction is a key step in the determination of sulfonylurea herbicides (SUHs) in complicated samples. According to the chemical properties of SUHs, a new monolithic adsorbent utilizing acrylamidophenylboronic acid and vinylimidazole as mixed functional monomers was synthesized. The new adsorbent was employed as the extraction phase of multiple monolithic fiber solid-phase microextraction (MMF-SPME) of SUHs, and the extracted SUHs were determined by high-performance liquid chromatography with diode array detection (HPLC-DAD). Results well evidence that the prepared adsorbent could extract SUHs in environmental waters and soil effectively through multiply interactions such as boronate affinity, dipole-dipole and pi-pi interactions. Under the optimized extraction conditions, the limits of detection for target SUHs in environmental water and soil samples were 0.018-0.17MUg/L and 0.14-1.23MUg/kg, respectively. At the same time, the developed method also displayed some analytical merits including wide linear dynamic ranges, good method reproducibility, satisfactory sensitivity and low consume of organic solvent. Finally, the developed were successfully applied to monitor trace SUHs in environmental water and soil samples. The recoveries at three fortified concentrations were in the range of 70.6-119% with RSD below 11% in all cases. The obtained results well demonstrate the excellent practical applicability of the developed MMF-SPME-HPLC-DAD method for the monitoring of SUHs in water and soil samples. PMID- 29174137 TI - Multimodality Imaging Spectrum of the Extranodal Lymphomas in the Head and Neck-A Pictorial Review. AB - Lymphoma is the second most common malignant neoplasm of the head and neck region, involving the nodal and/or extranodal sites or both in a variable fashion. Lymphoma may mimic a variety of tumors in this region depending on the subsite involved. The usual presentation of lymphomatous disease is presence of multiple enlarged, often conglomerate, lymph nodes without significant necrosis. Extranodal lymphomas demonstrate more complex radiologic features, but careful evaluation can identify distinct imaging patterns to suggest extranodal lymphomatous disease from other more common lesions. Knowledge of these imaging features can help raise suspicion for lymphoma as a differential consideration. This can be of critical importance since further work-up and management can be vastly different between lymphomatous disease and other disease entities. The authors present a pictorial review of the spectrum of imaging findings in extranodal head and neck lymphomas.

PMID- 29174139 TI - Altered TGF-beta endocytic trafficking contributes to the increased signaling in Marfan syndrome. AB - The main cardiovascular alteration in Marfan syndrome (MFS) is the formation of aortic aneurysms in which augmented TGF-beta signaling is reported. However, the primary role of TGF-beta signaling as a molecular link between the genetic mutation of fibrillin-1 and disease onset is controversial. The compartmentalization of TGF-beta endocytic trafficking has been shown to determine a signaling response in which clathrin-dependent internalization leads to TGF-beta signal propagation, and caveolin-1 (CAV-1) associated internalization leads to signal abrogation. We here studied the contribution of endocytic trafficking compartmentalization to increased TGF-beta signaling in vascular smooth muscle cells (VSMC) from MFS patients. We examined molecular components involved in clathrin- (SARA, SMAD2) and caveolin-1- (SMAD7, SMURF2) dependent endocytosis. Marfan VSMC showed higher recruitment of SARA and SMAD2 to membranes and their increased interaction with TGF-beta receptor II, as well as higher colocalization of SARA with the early endosome marker EEA1. We assessed TGF-beta internalization using a biotinylated ligand (b-TGF-beta), which colocalized equally with either EEA1 or CAV-1 in VSMC from Marfan patients and controls. However, in Marfan cells, colocalization of b-TGF-beta with SARA and EEA1 was increased and accompanied by decreased colocalization with CAV-1 at EEA1-positive endosomes. Moreover, Marfan VSMC showed higher transcriptional levels and membrane enrichment of RAB5. Our results indicate that increased RAB5-associated SARA localization to early endosomes facilitates its TGF-beta receptor binding and phosphorylation of signaling mediator SMAD2 in Marfan VSMC. This is accompanied by a reduction of TGF-beta sorting into multifunctional vesicles containing cargo from both internalization pathways. PMID- 29174140 TI - Relation of Coronary Artery Calcium and Extra-Coronary Aortic Calcium to Incident Hypertension (from the Multi-Ethnic Study of Atherosclerosis). AB - Arterial calcification reflects an atherosclerotic process associated with vascular stiffness. Whether baseline coronary artery calcium (CAC) and extra coronary calcium (ECC), measured using noncontrast computed tomography imaging, are associated with incident hypertension is poorly understood. We studied participants from the Multi-Ethnic Study of Atherosclerosis without measured or self-reported hypertension at baseline. Incident hypertension was defined by blood pressure criteria (BP, >=140/90 mmHg), BP medication use, or both, and was assessed at in-person visits. We analyzed incident hypertension using multivariable-adjusted discrete-time proportional hazards models. Net reclassification improvement (NRI) assessed whether CAC reclassified hypertension risk when added to the Framingham hypertension risk score. Among 3,304 subjects analyzed, mean age was 59 +/- 10 years; 48% were male and 42% were white. There were 1,283 incident hypertension cases over a median (interquartile range) follow up time of 10.6 (4.5, 11.5) years. Each 1-unit increase in ln(CAC+1) was independently associated with a 12% higher risk of hypertension (95% confidence interval [CI] 9% to 16%). Relative to CAC = 0, patients with CAC >400 had a hazard ratio for incident hypertension of 2.2 (95% CI 1.8 to 2.9). There was no interaction by age, gender, or baseline BP (p = 0.43, 0.19, 0.09, respectively). Continuous NRI analyses demonstrated that CAC can reclassify risk of incident hypertension; NRI = 0.19 (95% CI 0.10 to 0.26). Furthermore, all measurements of ECC were significantly associated with incident hypertension, even after adjustment for CAC (hazard ratios ranging from 1.36 to 1.38). In conclusion, patients with CAC and ECC are at markedly higher risk of incident hypertension and may benefit from more intensified prevention efforts. PMID- 29174141 TI - Stability of virus-like particles of red-spotted grouper nervous necrosis virus in the aqueous state, and the vaccine potential of lyophilized particles. AB - Virus-like particles (VLPs) are multi protein complexes mimicking the structural properties of the native virus. The development of freeze-dried formulations of such complex protein structures remains a challenge. Red-spotted grouper nervous necrosis virus (RGNNV) causes mass mortality in fish culture, and RGNNV VLPs have been suggested to be promising vaccine candidates. In the present study, the stability of RGNNV VLPs in the liquid state was investigated over a 4-week period, along with the influence of freeze-drying on VLP stability. RGNNV VLPs were completely degraded after one week at 37 degrees C followed by 3 weeks at ambient temperature, and they were partially degraded after 4 weeks at 4 degrees C. Therefore, the inherent stability of RGNNV VLP in an aqueous milieu is insufficient for long-term storage. When RGNNV VLPs were freeze-dried in the presence or absence of sugar stabilizers, sorbitol was found to improve VLP stability whereas mannitol reduced it. VLP preparations freeze-dried with sorbitol or without stabilizer were as immunogenic as control (non-freeze dried) VLPs, whereas VLPs freeze-dried in mannitol were less immunogenic. These results indicate that freeze-dried RGNNV VLPs have potential as vaccines. PMID- 29174142 TI - Estimating probability of insemination success using milk progesterone measurements. AB - The aim of this study was to quantify the effects of progesterone profile features and other cow-level factors on insemination success to provide a real time predictor equation of probability of insemination success. Progesterone profiles from 26 dairy herds were analyzed and the effects of profile features (progesterone slope, cycle length, and cycle height) and cow traits (milk yield, parity, insemination during the previous estrus) on likelihood of artificial insemination success were estimated. The equation was fitted on a training data set containing data from 16 herds (6,246 estrous cycles from 3,404 lactations). The equation was tested on a testing data set containing data from 10 herds (8,105 estrous cycles from 3,038 lactations). Predictors were selected to be implemented in the final equation if adding them to a base model correcting for timing of insemination and parity decreased the overall likelihood distance of the model. Selected variables (cycle length, milk yield, cycle height, and insemination during the previous estrus) were used to build the final model using a stepwise approach. Predictors were added 1 by 1 in different order, and the model that had the smallest likelihood distance was selected. The final equation included the variables timing of insemination, parity, milk yield, cycle length, cycle height, and insemination during the previous estrus, respectively. The final model was applied to the testing data set and area under the curve (AUC) was calculated. On the testing data set, the final model had an AUC of 58%. When the farm effect was taken into account, the AUC increased to 63%. This equation can be implemented on farms that monitor progesterone and can support the farmer in deciding when to inseminate a cow. This can be the first step in moving the focus away from the current paradigm associated with poorer estrus detection, where each detected estrus is automatically inseminated, to near perfect estrus detection, where the question is which estrous cycle is worth inseminating? PMID- 29174143 TI - Intramammary infections with different non-aureus staphylococci in dairy cows. AB - Subclinical mastitis causes an increase in milk somatic cell count (SCC) and can lead to reduced milk production and early culling. In many countries, non-aureus staphylococci (NAS) is the most common bacterial finding in subclinical mastitis of dairy cows. New methodology makes it possible to identify NAS species, but knowledge about the epidemiology is limited. The objective of this project was to improve advisory services for mastitis control by investigating associations between NAS and SCC, milk production, and persistence of intramammary infections (IMI). Farmers who had sent milk samples to the Swedish National Veterinary Institute (Uppsala, Sweden) were asked to participate if NAS was identified in the samples. Participating farmers were asked to resample all udder quarters of the cow once within 1 mo. Regression models were used to investigate associations between NAS and cow factors, udder quarter California mastitis test and SCC, and persistence of IMI. Associations with cow composite milk yield and SCC were also investigated. In total, 671 cows from 201 herds were enrolled in the study, and 19 NAS species were identified, of which the 4 most common were Staphylococcus epidermidis, Staphylococcus simulans, Staphylococcus chromogenes, and Staphylococcus haemolyticus. Persistent IMI was more common in udder quarters with Staphylococcus hyicus and S. simulans and less common in those with Staphylococcus saprophyticus IMI. beta-Lactamase production by the different NAS species varied from 0 to 100%. There was a significant association between NAS species and California mastitis test and SCC of udder quarters, and this varied depending on parity. The cow composite milk SCC at the test milking before the initial sample was taken differed significantly with NAS species, but not at the subsequent test milking. Milk yield-at the test milking before or after the initial sample-did not differ significantly for NAS species. There were no significant associations between milk yield or SCC and persistent NAS IMI. In conclusion, the NAS species affects SCC and persistent IMI differently but not milk yield. PMID- 29174144 TI - Factors associated with herd bulk milk composition and technological traits in the Italian dairy industry. AB - The aim of the present study was to investigate sources of variation of milk composition and technological characteristics routinely collected in field conditions in the Italian dairy industry. A total of 40,896 bulk milk records from 620 herds and 10 regions across Italy were analyzed. Composition traits were fat, protein, and casein percentages, urea content, and somatic cell score; and technological characteristics were rennet coagulation time, curd firming time, curd firmness 30 min after rennet addition to milk, and titratable acidity. Data of herd bulk milks were analyzed using a model that included fixed effects of region, herd nested within region, and season of milk analysis. An average good milk quality was reported in the dairy industry (especially concerning fat, protein, and casein percentages), and moderate to high correlations between composition and technological traits were observed. All factors included in the statistical model were significant in explaining the variation of the studied traits except for region effect in the analysis of casein and somatic cell score. Northeast and central-southern Italian regions showed the best performance for composition and technological features, respectively. Traits varied greatly across regions, which could reflect differences in herd management and strategies. Overall, less suitable milk for dairy processing was observed in summer. Results of the present study suggested that a constant monitoring of technological traits in the dairy industry is necessary to improve production quality at herd level and it may be a way to segregate milk according to its processing characteristics. PMID- 29174145 TI - Using video microscopy to improve quantitative estimates of protozoal motility and cell volume. AB - The objective of this study was to apply digital imaging to improve quantification of rumen protozoal biomass and distinguish treatment differences in cell motility and volume among ruminal protozoa. Observations of protozoa in rumen fluid treated with essential oils (CinnaGar, CIN; Provimi North America, Brookville, OH) or an ionophore (monensin, MON) indicated possible cell shrinkage. We hypothesized that MON would decrease protozoal motility and interact with CIN on cell volume. In addition, we hypothesized that analysis of still frames from video of swimming protozoa would improve volume prediction accuracy. Flocculated rumen fluid was incubated in batch culture dosed with N free feed only (control), MON, CIN, or a combination of MON+CIN. Samples were taken at 0, 3, or 6 h post-treatment and wet-mounted on a microscope fitted with a high-definition camera. At 3 h post-inoculation, there was a treatment interaction for average speed such that CIN attenuated the effect of MON, with treatment means of 243, 138, 211, and 183 um/s for control, MON, CIN, and MON+CIN, respectively. At 6 h post-inoculation, MON decreased average speed by 79.2 um/s compared with the main effect mean without MON. We measured both minimum and maximum diameters (depth and width, respectively) perpendicular to the longitudinal axis of swimming protozoa, yielding a 3-dimensional estimate of protozoal volume. The ellipsoid formula (4/3)piabc, where a = 1/2 length, b = 1/2 width, and c = 1/2 depth, was compared with previously published volume estimations using genera-specific coefficients (genera-specific coefficient * length * width2). Residuals (genera-specific coefficients - ellipsoid) were plotted against predicted (ellipsoid) and centered to the mean (Xi-x-) to evaluate both mean and slope biases. For Entodinium spp., Y = 0.248 (+/-0.037) (Xi - 7.98 * 104) + 1.97 * 104 (+/-1.48 * 103); n = 100; r2 [coefficient of determination (squared correlation coefficient)] = 0.31, with significant slope and mean biases. For family Isotrichidae, Y = -0.124 (+/-0.068) (Xi - 2.54 * 106) - 1.21 * 104 (+/-4.86 * 104); n = 32; r2 = 0.10, where slope tended to be different from zero but with no mean bias. For Epidinium spp., Y = 0.375 (+/ 0.056) (Xi - 2.45 * 105) + 6.65 * 104 (+/-0.28 * 104); n = 64; r2 = 0.43, with both mean and slope biases. The present regression analyses demonstrate that the genera-specific coefficient-based method more likely overestimates volume for Entodinium and Epidinium than for the teardrop-shaped Isotrichidae. Based on simulations derived from previous literature reporting treatments that depress protozoal populations or among-animal changes in protozoal population structures, our proposed ellipsoid method offers potential to advance the prediction of treatment effects on protozoal volume and to shift focus from the number of cells present to the diversity, function, and biomass of protozoa under various treatment conditions. PMID- 29174146 TI - Characteristics of feed efficiency within and across lactation in dairy cows and the effect of genetic selection. AB - The objective of the present study was to investigate the phenotypic inter- and intra-relationships within and among alternative feed efficiency metrics across different stages of lactation and parities; the expected effect of genetic selection for feed efficiency on the resulting phenotypic lactation profiles was also quantified. A total of 8,199 net energy intake (NEI) test-day records from 2,505 lactations on 1,290 cows were used. Derived efficiency traits were either ratio based or residual based; the latter were derived from least squares regression models. Residual energy intake (REI) was defined as NEI minus predicted energy requirements based on lactation performance; residual energy production (REP) was defined as net energy for lactation minus predicted energy requirements based on lactation performance. Energy conversion efficiency was defined as net energy for lactation divided by NEI. Pearson phenotypic correlations among traits were computed across lactation stages and parities, and the significance of the differences was determined using the Fisher r-to-z transformation. Sources of variation in the feed efficiency metrics were investigated using linear mixed models, which included the fixed effects of contemporary group, breed, parity, stage of lactation, and the 2-way interaction of parity by stage of lactation. With the exception of REI, parity was associated with all efficiency and production traits. Stage of lactation, as well as the 2 way interaction of parity by stage of lactation, were associated with all efficiency and production traits. Phenotypic correlations among the efficiency and production traits differed not only by stage of lactation but also by parity. For example, the strong phenotypic correlation between REI and energy balance (EB; 0.89) for cows in parity 3 or greater and early lactation was weaker for parity 1 cows at the same lactation stage (0.81), suggesting primiparous cows use the ingested energy for both milk production and growth. Nonetheless, these strong phenotypic correlations between REI and EB suggested negative REI animals (i.e., more efficient) are also in more negative EB. These correlations were further supported when assessing the effect on phenotypic performance of animals genetically divergent for feed intake and efficiency based on parental average. Animals genetically selected to have lower REI resulted in cows who consumed less NEI but were also in negative EB throughout the entire lactation. Nonetheless, such repercussions of negative EB do not imply that selection for negative REI (as defined here) should not be practiced, but instead should be undertaken within the framework of a balanced breeding objective, which includes traits such as reproduction and health. PMID- 29174147 TI - Predicting nutrient digestibility in high-producing dairy cows. AB - Our objective was to determine the effects of dry matter intake (DMI), body weight (BW), and diet characteristics on total tract digestibilities of dry matter, neutral detergent fiber, and starch (DMD, NDFD, and StarchD, respectively) in high-producing dairy cows. Our database was composed of 1,942 observations from 662 cows in 54 studies from Michigan, Ohio, and Georgia. On average, cows ate 23 +/- 4.5 kg of dry matter/d, weighed 669 +/- 79 kg, and produced 38 +/- 10 kg of milk/d. Diets were 31 +/- 5% neutral detergent fiber, 27 +/- 6% starch, 2.6 +/- 1.2% fatty acids, and 17 +/- 1.4% crude protein. Digestibility means were 66 +/- 6, 42 +/- 11, and 93 +/- 5% for DMD, NDFD, and StarchD, respectively. Forage sources included corn silage, alfalfa, and grasses. Corn source was classified by its ruminal fermentability. Data were analyzed using a mixed effects model, including diet chemical composition, forage source, and corn source, all expressed as percentage of dry matter, except for DMI, which was expressed as percentage of BW (DMI%BW); location and 2-way interactions were fixed effects. Cow, block, period, treatment, and study were included as random effects. Best fitting candidate models were generated using backward and stepwise regression methods. Additionally, the simplest model was generated using only DMI and location as fixed effects and all random effects. Candidate models were cross validated across studies, and the resulting predictive correlation coefficients across studies (PC) and root mean square error of prediction (RMSEP) were compared by t-test. For each nutrient, the digestibility model that resulted in the highest PC and lowest RMSEP was determined to be the best fitting model. We observed heterogeneous coefficients among the different locations, suggesting that specific location factors influenced digestibilities. The overall location averaged best fitting prediction equations were: DMD = 69 - 0.83 * DMI%BW (PC = 0.22, RMSEP = 5.39); NDFD = 53 + 0.26 * grass %DM - 0.59 * starch %DM + 3.06 * DMI%BW - 0.46 * DMI%BW2 (PC = 0.53, RMSEP = 9.70); and StarchD = 96 + 0.19 * HFERM%DM - 0.12 * starch %DM - 1.13 * DMI%BW (PC = 0.34, RMSEP = 4.77); where HFERM%DM is highly-fermentable corn source as percentage of DM. Our results confirm that digestibility is reduced as DMI increases, albeit at a lower rate than that reported in National Research Council. Furthermore, dietary starch depresses NDFD. Whereas DMD can be predicted based on DMI only, the best predictions for NDFD and StarchD require diet characteristics in addition to DMI. PMID- 29174148 TI - Short communication: Does early-life administration of a Megasphaera elsdenii probiotic affect long-term establishment of the organism in the rumen and alter rumen metabolism in the dairy calf? AB - Megasphaera elsdenii is a bacterial species of the rumen that can utilize lactate to produce butyrate, a key volatile fatty acid often implicated in driving calf rumen development. Because lactate is abundant in the rumen of young calves, administration of M. elsdenii to increase butyrate production and thus promote calf rumen development is an appealing possibility. The main objective of this study was to determine whether M. elsdenii administration to calves via oral drench at 14 d of age affected its long-term establishment at 70 d postadministration. Ruminal volatile fatty acid and lactate profiles and blood glucose and beta-hydroxybutyrate concentrations were also examined to determine potential influence on rumen metabolism. Six neonatal Holstein heifer calves were blocked on d 1 by body weight (41.3 +/- 1.8 kg) and total serum protein (5.23 +/- 0.16 g/dL) and assigned to either the M. elsdenii (n = 3) or control (n = 3) treatment groups. On d 14, calves in the M. elsdenii group orally received 25 mL of a commercially available M. elsdenii suspension, whereas calves in the control group received 25 mL of the same product that had been autoclaved. Rumen contents and blood samples were collected weekly from each animal until 84 d of age. The oral administration of M. elsdenii at 14 d did not increase the abundance of M. elsdenii 70 d postdosing, alter rumen fermentation, or change blood metabolites associated with butyrate. These results suggest that a single administration of the M. elsdenii probiotic may not affect the rumen establishment of the organism. PMID- 29174149 TI - Plasma calcium concentrations are decreased at least 9 hours before parturition in multiparous Holstein-Friesian cattle in a herd fed an acidogenic diet during late gestation. AB - Calcium homeostatic mechanisms are challenged in periparturient multiparous dairy cattle due to the rapid transport of large amounts of calcium into the mammary gland associated with colostrogenesis, resulting in decreased plasma total calcium concentration ([Ca]). An unresolved issue is the timing of the decrease in plasma [Ca] relative to the time of parturition, with the consensus view being that plasma [Ca] does not decrease until after parturition. The objective of this study, therefore, was to characterize the change in plasma [Ca] over time in periparturient dairy cattle. Plasma and mid-stream urine samples were collected daily starting 3 d before calving from 104 periparturient Holstein-Friesian dairy cows in a herd fed an acidogenic total mixed ration during the late dry period. Mixed-models ANOVA and linear and multivariable regression analyses were conducted. Plasma [Ca] decreased in periparturient multiparous cattle (n = 70) but not in primiparous cattle (n = 34). Compared with mean values approximately 72 h before parturition ([Ca] = 2.32 mmol/L), mean plasma [Ca] in multiparous cattle first decreased at 9 h before parturition (2.13 mmol/L) and remained decreased for up to 48 h after parturition, with the lowest mean value (1.87 mmol/L) occurring at 28 h after parturition. Mean 24-h urine Ca excretion was calculated to decrease by 3.5 to 3.8 g in periparturient multiparous cattle. Regression analysis indicated that plasma [Ca] in the 12-h period before and 24-h period after parturition was strongly and negatively associated with age but was also negatively associated with milk production indices. We conclude that plasma [Ca] was decreased at least 9 h before parturition in multiparous dairy cattle fed an acidogenic diet in late gestation, and that calcium homeostasis was disrupted for 2 to 3 d around parturition.

AB - Utilization of nutrients to improve overall heifer health is of interest because of the importance of replacement heifers to the dairy industry. The objective of our study was to compare the effect of supplementation of dietary n-3 and n-6 fatty acids (FA) on FA concentrations in peripheral blood mononuclear cells (PBMC) of Holstein calves. Twenty-seven Holstein heifer calves (107 +/- 2.6 d of age; 142.6 +/- 6.5 kg of body weight) from the university research and teaching herd were randomly assigned to a common TMR supplemented with 1 of 3 treatments: Ca salts of flaxseed FA (Virtus Nutrition, Corcoran, CA) containing 35% 18:3 n-3 (N3), Ca salts of soybean FA (Virtus Nutrition) containing 50% 18:2 n-6 (N6), or a 50:50 mix of N3 and N6. Treatments were supplemented with FA at 4% of dietary dry matter and fed for 30 d. Feed intake was recorded daily, and body weight, wither height, and body condition score were measured weekly throughout the study. On d 28 heifers were vaccinated with a Pasteurella vaccine and the temperature response to the vaccine was recorded. Blood was collected on d 0 and 28 for PBMC isolation. After total lipid extraction and FA methyl ester preparation, FA composition of PBMC was measured. We observed no effect of treatment on body weight gain, body condition score change, or wither height change. Heifers receiving the N3 diet had a lower temperature response to Pasteurella challenge compared with both the mix and N6 diets. Heifers consuming the N3 diet had a greater content of total n-3 FA, alpha-linolenic acid, and eicosapentaenoic acid in PBMC compared with heifers fed the N6 and mix diets. Heifers receiving the N3 diet also had a lower content of total n-6 FA, linoleic acid, and arachidonic acid in PBMC than heifers fed the N6 and mix diets. In conclusion, our study determined that feeding weaned female Holstein heifers a diet high in n-3 FA increased concentrations of n-3 FA in PBMC. PMID- 29174151 TI - Meta-analysis of the effect of white clover inclusion in perennial ryegrass swards on milk production. AB - There is increased demand for dairy products worldwide, which is coupled with the realization that consumers want dairy products that are produced in a sustainable and environmentally benign manner. Forage legumes, and white clover (Trifolium repens L.; WC) in particular, have the potential to positively influence the sustainability of pasture-based ruminant production systems. Therefore, there is increased interest in the use of forage legumes because they offer opportunities for sustainable pasture-based production systems. A meta-analysis was undertaken to quantify the milk production response associated with the introduction of WC into perennial ryegrass swards and to investigate the optimal WC content of dairy pastures to increase milk production. Two separate databases were created. In the grass-WC database, papers were selected if they compared milk production of lactating dairy cows grazing perennial ryegrass-WC (GC) swards with that of cows grazing perennial ryegrass-only swards (GO). In the WC-only database, papers were selected if they contained milk production from lactating dairy cows grazing on GC swards with varying levels of WC content. Data from both databases were analyzed using mixed models (PROC MIXED) in SAS (SAS Institute, Cary, NC). Within the grass-WC database, where mean sward WC content was 31.6%, mean daily milk and milk solids yield per cow were increased by 1.4 and 0.12 kg, respectively, whereas milk and milk solids yield per hectare were unaffected when cows grazed GC compared with GO swards. Stocking rate and nitrogen fertilizer application were reduced by 0.25 cows/ha and 81 kg/ha, respectively, on GC swards compared with GO swards. These results highlight the potential of GC production systems to achieve similar levels of production to GO systems but with reduced fertilizer nitrogen inputs, which is beneficial from both an economic and environmental point of view. In the context of increased demand for dairy products, there may be potential to increase the productivity of GC systems by increasing fertilizer nitrogen use to increase stocking rate and carrying capacity while also retaining the benefit of WC inclusion on milk production per cow. PMID- 29174152 TI - Predicting omasal flow of nonammonia N and milk protein yield from in vitro determined utilizable crude protein at the duodenum. AB - This study evaluated the relationship between utilizable crude protein (uCP) at the duodenum estimated in vitro and omasal flow of crude protein (CP; omasal flow of nonammonia N * 6.25) measured in lactating dairy cows. In vivo data were obtained from previous studies estimating omasal digesta flow using a triple marker method and 15N as microbial marker. A total of 34 different diets based on grass and red clover silages were incubated with buffered rumen fluid previously preincubated with carbohydrates for 3 h. The buffer solution was modified to contain 38 g of NaHCO3 and 1 g of (NH4)HCO3 in 1,000 mL of distilled water. Continuous sampling of the liquid phase for determination of ammonia-N was performed at 0.5, 4, 8, 12, 24, and 30 h after the start of incubation. The ammonia N concentrations after incubation were used to calculate uCP. The natural logarithm of uCP [g/kg of dry matter (DM)] at time points 0.5, 4, 8, 12, 24, and 30 h of incubation was plotted against time to estimate the concentration of uCP (g/kg of DM) at time points 16, 20, and 24 h using an exponential function. Fixed model regression analysis and mixed model regression analysis with random study effect were used to evaluate the relationships between predicted uCP (supply and concentration) and observed omasal CP flow and milk protein yield. Residual analysis was also conducted to evaluate whether any dietary factors influenced the relationships. The in vitro uCP method ranked the diets accurately in terms of total omasal CP flow (kg/d) or omasal CP flow per kilogram of DM intake. We also noted a close relationship between estimated uCP supply and adjusted omasal CP flow, as demonstrated by a coefficient of determination of 0.87, although the slope of 0.77 indicated that estimated uCP supply (kg/d) was greater than the value determined in vivo. The linear bias with mixed model analysis indicated that uCP supply overestimated the difference in omasal CP flow between the diets within a study, an error most likely related to study differences in feed intake, animals, and methodology. Predicting milk protein yield from uCP supply showed a positive relationship using a mixed model (coefficient of determination = 0.79), and we observed no difference in model fit between the time points of incubation (16, 20, or 24 h). The results of this study indicate that the in vitro method can be a useful tool in evaluating protein value of ruminant diets. PMID- 29174153 TI - Technical note: Development and evaluation of a standard operating procedure for ultrasound-based measurements of teat canal dimensions in dairy cows. AB - The objectives were to (1) develop a standard operating procedure (SOP) for ultrasound-based measurements of teat canal dimensions and (2) determine the precision of ultrasound-based measurements of teat canal dimensions in dairy cows. Teat scans (n = 64) of the right hind and left front teats from 16 cows were obtained with a portable ultrasound device before and after machine milking. Teat dimensions measured were teat canal length (TCL), teat canal diameter at the proximal end of the teat canal (TCDPROX), teat canal diameter at the midpoint between the proximal and distal ends of the teat canal (TCDMID), teat canal diameter at the distal end of the teat canal (TCDDIS), teat end diameter at the midpoint between the proximal and distal ends of the teat canal (TMD), and teat canal cross-sectional area (TCLAREA). An SOP was developed, reviewed, and modified by 3 operators. Measurements were performed by the same 3 operators using an open source software program. To assess the effect of implemented modifications and the precision of ultrasound-based measurements, concordance correlation coefficients (CCC) were calculated to determine interoperator reproducibility and intraoperator repeatability. Through modifications in the SOP, interoperator CCC increased from 0.45 to 0.86 for TCL, from 0.14 to 0.66 for TCDPROX, from 0.24 to 0.66 for TCDMID, from 0.06 to 0.56 for TCDDIS, from 0.64 to 0.91 for TMD, and from 0.17 to 0.64 for TCLAREA. Intraoperator CCC over all operators were 0.91 for TCL, 0.73 for TCDPROX, 0.80 for TCDMID, 0.69 for TCDDIS, 0.94 for TMD, and 0.75 for TCLAREA. Our results indicate that measurements of teat canal dimensions can be conducted with satisfactory precision when following an SOP. Development and strict implementation of an SOP has the potential to decrease inadvertent variability of ultrasound-based measurements among operators for ultrasonographic assessment of teat dimensions. PMID- 29174155 TI - Genetic parameters for yield, fitness, and type traits in US Brown Swiss dairy cattle. AB - The objective of this research was to evaluate heritabilities and genetic correlations among yield, fitness, and type traits for US Brown Swiss cattle born in 2000 and later. The data set used consisted of 108,633 first through fifth lactation records from 45,464 cows for yield, somatic cell score (SCS), days open, and productive life. Approximately half of the records had observations for 17 type traits and 41,074 had observations for milking speed. These data were analyzed using a series of 3 trait models. Heritability estimates of each trait were similar to previously reported values for both Holsteins, and Brown Swiss in other countries. Milk, fat, and protein yield had strong positive genetic correlations with productive life (0.67 to 0.71), whereas days open and SCS had strong negative correlations with productive life (-0.60 and -0.69, respectively). Days open was more unfavorably correlated with dairy form (angularity) than with yield. The genetic correlation of udder depth and milk yield was unfavorable (-0.40), whereas rear udder height (0.20) and width (0.48) were favorably correlated with milk yield. Udder depth had a favorable genetic correlation with SCS (-0.26). Type traits with the strongest genetic correlations with productive life were fore udder attachment, mobility, and final score (0.44, 0.50, and 0.57, respectively). These updated genetic parameters will allow for improved genetic selection within the Brown Swiss breed. PMID- 29174154 TI - Reduced serum vitamin D concentrations in healthy early-lactation dairy cattle. AB - Cattle obtain vitamin D by ingestion or cutaneous exposure to UV light. Dairy cattle diets are frequently supplemented with vitamin D to compensate for limited sun exposure or during times of increased metabolic demands, such as the periparturient period, to maintain calcium homeostasis. Whether housing and supplemental vitamin D practices supply adequate amounts of vitamin D to optimally support the transition from gestation to lactation in dairy cattle is unknown. Our objective was to determine how serum vitamin D concentrations of dairy cows change with season, age, parity, and stage of lactation. Clinically healthy cows (n = 183) from 5 commercial dairies were enrolled in the study. Serum samples were collected at dry off, within 7 d of entering the close-up group, and within 7 d after calving (calving+7). Vitamin D status was determined by measuring serum 25-hydroxyvitamin D [25(OH)D] by radioimmunoassay. We performed repeated-measures mixed-effects linear regression to determine the effects of season, age, parity, and lactation stage (dry off, close-up, and calving+7) on 25(OH)D concentrations in serum. Bivariable analysis indicated that parity, age, and season were not associated with serum 25(OH)D concentrations. Sample period affected 25(OH)D concentrations, with the highest 25(OH)D levels at dry off (99.7 +/- 1.9 ng/mL) followed by close up (93.8 +/- 2.1 ng/mL), with the lowest levels at calving+7 (82.6 +/- 1.7 ng/mL). These data showed a large depletion of 25(OH)D in dairy cattle postpartum compared with late prepartum, although the biological significance of this change in these healthy cattle is unclear. Consumption of serum 25(OH)D by immune system functions and calcium homeostasis in early lactation likely caused the reduction in serum 25(OH)D concentrations after calving. These results suggest that determining whether serum 25(OH)D concentrations are associated with the incidence of transition period disease is an appropriate next step. Assessing the effects of enhanced vitamin D supplementation of cows in early lactation on postpartum diseases may be warranted. PMID- 29174156 TI - Comprehensive analysis of proteolysis during 8 months of ripening of high-cooked Old Saare cheese. AB - We applied capillary electrophoresis, liquid chromatography coupled with tandem mass-spectrometry (MS/MS), and ultra-performance liquid chromatography to determine the composition of water-insoluble and water-soluble proteinaceous fractions of the cheese and to study in detail the degradation of caseins during 8 mo of ripening of Estonian high-temperature cooked hard cheese Old Saare. The application of high-resolution and high-accuracy MS/MS enabled identification of more than 3,000 small peptides, representing a fairly full casein peptidome containing peptides of 4 to 25 AA in length: 1,049 from beta-casein (CN), 944 from alphaS1-CN, 813 from alphaS2-CN, and 234 from kappa-CN. The majority of beta CN- and alphaS1-CN-derived peptides originated from the N-terminal parts of the molecule, f6-93 and f1-124, respectively; peptides from alphaS2-CN arose predominantly from the C-terminal end f100-162. At the beginning of ripening, we found a relatively high amount of peptides originating from the glycomacropeptide part of kappa-CN, whereas peptides from para-kappa-CN prevailed during the later stages of ripening of the cheese. The cleavage patterns of beta-CN, alphaS2-CN, as well as alphaS1-CN, showed that primary proteolysis was started mainly by plasmin, although a low proteolytic activity of chymosin was also evident. Based on the analysis of cleavage sites, we observed a significant participation of proteolytic enzymes, including amino- and carboxypeptidases, of both mesophilic and thermophilic starter bacteria in further hydrolysis of oligopeptides during the ripening. Several new phosphopeptides were detected in the result of MS/MS data analysis. The profiles of the estimated concentrations of phosphopeptides revealed that those originating from beta-CN and alphaS1-CN accumulated during cheese maturation. In contrast, we did not notice any generation of phosphopeptides from the highly phosphorylated part of alphaS2-CN, f25-80, presumably due to the inaccessibility of this region to the action of plasmin and chymosin. The analysis of cleavage sites and the combination of principal component and clustering analyses provided a characterization of the complex dynamics of formation and degradation of peptides during cheese maturation. We made an attempt to obtain a comprehensive picture of proteolysis during Old Saare cheese ripening on the basis of the detailed peptidomic data, including also the less abundant peptides determined by MS/MS, and complemented by the data on intact caseins and free AA and reported the results in the paper. PMID- 29174157 TI - The contribution of previous lameness events and body condition score to the occurrence of lameness in dairy herds: A study of 2 herds. AB - It has been demonstrated that low body condition and previous occurrence of lameness increase the risk of future lameness in dairy cows. To date the population attributable fraction (PAF), which provides an estimate of the contribution that a risk factor makes toward the total number of disease events in a population, has not been explored for lameness using longitudinal data with repeated measures. Estimation of PAF helps to identify control measures that could lead to the largest improvements on-farm. The aim of this study was to use longitudinal data to evaluate the proportion of lameness that could be avoided in 2 separate herds (2 populations) through (1) reduced recurrence of previous lameness events, (2) and moving body condition score (BCS) into more optimal ranges. Data were obtained from 2 UK dairy herds: herd A, a 200-cow herd with 8 yr of data from a total of 724 cows where lameness events were based on weekly locomotion scores (LS; 1 to 5 scale), and herd B, a 600-cow herd with data recorded over 44 mo from a total of 1,040 cows where treatment of clinical cases was used to identify lameness events. The PAF for categories of BCS were estimated using a closed equation appropriate for multiple exposure categories. Simulation models were used to explore theoretical scenarios to reflect changes in BCS and recurrence of previous lameness events in each herd. For herd A, 21.5% of the total risk periods (cow-weeks) contained a lameness event (LS 3, 4, or 5), 96% of which were repeat events and 19% were recorded with BCS <2 (3 wk previously; 0 to 5 scale). When lameness events were based on 2 consecutive weeks of LS 4 or 5, 4% of risk periods were recorded as lame, of which 89.5% were repeat events. For herd B, 16.3% of the total risk periods (consecutive 30 d) contained a lameness event (72.6% were repeat events) and 20% were recorded with BCS <=2 (0 to 120 d previously). The median PAF for all previous lameness was between 79 and 83% in the 2 herds. Between 9 and 21% of lameness events could be attributed to previous lameness occurring >16 wk before a risk period. The median PAF estimated for changes in BCS were in the region of 4 to 11%, depending on severity of lameness. Repeated bouts of lameness made a very large contribution to the total number of lameness events. This could either be because certain cows are initially susceptible and remain susceptible, due to the increased risk associated with previous lameness events, or due to interactions with environmental factors. This area requires further research. PMID- 29174158 TI - Symposium review: Lipids as regulators of conceptus development: Implications for metabolic regulation of reproduction in dairy cattle. AB - Pregnancy losses are substantial in dairy cattle and threaten reproductive efficiency. A substantial proportion of these losses occur during early stages of conceptus development, including the elongation phase. Elongation of the preimplantation conceptus is a prerequisite for maternal recognition, implantation, and survival of pregnancy. The onset of elongation occurs when concentrations of lipids in endometrial epithelial cells are increased, and it requires substantial coordination of lipid metabolism by conceptus cells. The nuclear receptor peroxisome proliferator-activated receptor gamma (PPARgamma) seems to have a central role in coordinating gene expression in trophectoderm cells at the onset of elongation, particularly of genes involved in lipid metabolism. Numerous fatty acids are natural ligands of PPARgamma and their concentrations in the histotroph are likely important to PPARgamma activity and its downstream effects on conceptus biology. Changes in concentration or composition of fatty acids in the histotroph could alter conceptus development. Inflammatory diseases and excessive loss of body reserves are prevalent problems in postpartum dairy cows and represent important risk factors for early pregnancy loss in the subsequent breeding period. Although cows affected by these conditions likely have reduced developmental capacity of oocytes, embryo transfer studies indicate that impaired uterine environment also contributes to their subfertility. Long-lasting effects of these conditions on energy and lipid homeostasis might alter composition of the histotroph and could help explain developmental failures occurring during conceptus formation attributable to impaired uterine environment. Targeting of uterine lipid metabolism and PPARgamma activity during preimplantation conceptus development through prevention of disease and optimized feed intake postpartum and through nutraceutical diets at the time of breeding are potential strategies to improve pregnancy survival and consequently reproductive efficiency in dairy cows. PMID- 29174159 TI - Fluctuations in milk yield are heritable and can be used as a resilience indicator to breed healthy cows. AB - Automatic milking systems record an enormous amount of data on milk yield and the cow itself. These type of big data are expected to contain indicators for health and resilience of cows. In this study, the aim was to define and estimate heritabilities for traits related with fluctuations in daily milk yield and to estimate genetic correlations with existing functional traits, such as udder health, fertility, claw health, ketosis, and longevity. We used daily milk yield records from automatic milking systems of 67,025 lactations in the first parity from 498 herds in the Netherlands. We defined 3 traits related to the number of drops in milk yield using Student t-tests based on either a rolling average (drop rolling average) or a regression (drop regression) and the natural logarithm of the within-cow variance of milk yield (LnVar). Average milk yield was added to investigate the relationships between milk yield and these new traits. ASReml was used to estimate heritabilities, breeding values (EBV), and genetic correlations among these new traits and average milk yield. Approximate genetic correlations were calculated using correlations between EBV of the new traits and existing EBV for health and functional traits correcting for nonunity reliabilities using the Calo method. Partial genetic correlations controlling for persistency and average milk yield and relative contributions to reliability were calculated to investigate whether the new traits add new information to predict fertility, health, and longevity. Heritabilities were 0.08 for drop rolling average, 0.06 for drop regression, and 0.10 for LnVar. Approximate genetic correlations between the new traits and the existing health traits differed quite a bit, with the strongest correlations (-0.29 to -0.52) between LnVar and udder health, ketosis, persistency, and longevity. This study shows that fluctuations in daily milk yield are heritable and that the variance of milk production is best among the 3 fluctuations traits tested to predict udder health, ketosis, and longevity. Using the residual variance of milk production instead of the raw variance is expected to further improve the trait to breed healthy, resilient, and long-lasting dairy cows. PMID- 29174160 TI - Effects of replacement of late-harvested grass silage and barley with early harvested silage on ruminal digestion efficiency in lactating dairy cows. AB - The objective of this experiment was to quantify the effects of graded replacement of late-harvested grass silage and barley with early-harvested silage on nutrient digestion and rumen fermentation. Four experimental diets were fed to 4 multiparous rumen-cannulated Nordic Red cows in 4 * 4 Latin square design with 21-d periods. Dietary treatments consisted of late-cut grass silage (LS) and rolled barley, which was gradually replaced with early-cut grass silage [ES; 0, 33, 67, and 100% of the forage component (ES + LS) of the diet]. With increased proportion of ES in the diet, the proportion of barley decreased from 47.2 to 26.6% on a dry matter basis. Early- and late-cut silages were harvested at 2-wk intervals (predicted concentrations of metabolizable energy 11.0 and 9.7 MJ/kg of dry matter). The 4 diets were formulated to support the same milk production. Nutrient flows were quantified using omasal sampling technique applying the triple-marker method (Cr, Yb, and indigestible neutral detergent fiber) and 15N as a microbial marker. Feed intake decreased with graded replacement of LS and barley with ES, but milk production was not influenced by diet. Digestibility of nutrients improved with graded addition of ES in the diet with the greatest difference observed in digestibility of neutral detergent fiber (NDF) and potentially digestible NDF (pdNDF). The results suggested that improved cell wall digestibility with graded level of ES in the diet was partly related to higher intrinsic digestibility of ES than LS, and partly due to negative associative effects with an increased proportion of LS and barley in the diet. Efficiency of microbial N synthesis was not influenced by the diet, but ruminal protein degradability increased with ES in the diet. Rumen fermentation pattern was not affected by the diet despite large difference in the profile of dietary carbohydrates. Rumen pool size of NDF and pdNDF, and ruminal turnover time of NDF decreased with graded addition of ES in the diet, whereas digestion rate of pdNDF improved. The results of this study indicate that increased CH4 yield in a parallel production study with graded addition of ES in the diet were more related to greater ruminal and total digestibility of organic matter than to the changes in rumen fermentation pattern.

PMID- 29174162 TI - Moving skills training closer to application: In-rotation skills curriculum is feasible and effective. AB - PURPOSE: Using simulation can help surgical trainees acquire surgical skills but at the expense of clinical learning time. We postulate an in-rotation skills curriculum is feasible and minimizes time away from clinical experiences. METHODS: Surgical residents (PGY2-5) were allotted two hours of weekly protected time for rotation specific simulation modules that included assessment, mentoring, and practice. Between September 2015 and February 2016 performance data was collected and participants were surveyed. RESULTS: Completion rates of 87-100% were achieved and post-test scores improved significantly, indicating improved performance. The survey (29/30 RR) revealed that 81.5% felt 2 hours a week was 'just right' and 79.3% agreed or strongly agreed the in-rotation aspect was a benefit. Improved confidence in the OR was reported by 86.2% of residents Intra-operative skill was self-assessed as improved in 79.3%. CONCLUSION: In rotation skills curriculum with high completion rates is feasible and allows training in close proximity to clinical application. Performance in the simulated environment significantly improved with corresponding improvements in confidence and self-assessed skill in the operating room. PMID- 29174163 TI - Cancer history: A predictor of IPMN subtype and dysplastic status? AB - INTRODUCTION: The aim of this study was to determine the association of PMH and FH of pancreatic (PDAC) and non-pancreatic cancers with IPMN malignant risk. METHODS: A retrospective review of a prospective database of IPMN patients undergoing resection was performed to assess FH and PMH. RESULTS: FH of PDAC was present in 13% of 362 included patients. Of these, 8% had at least one first degree relative (FDR) with PDAC. The rate of PDAC positive FH in non-invasive versus invasive IPMN patients was 14% and 8%, respectively (p = 0.3). In main duct IPMN patients, FH (44%) and PMH of non-pancreatic cancer (16%) was higher than that seen in branch duct IPMN (FH 29%; PMH 6%; p = 0.004 and 0.008). CONCLUSIONS: FH of PDAC is not associated with IPMN malignant progression. FH and PMH of non-pancreatic cancer is associated with main duct IPMN, the subtype with the highest rate of invasive transformation. PMID- 29174164 TI - Resident attitudes and compliance towards robotic surgical training. AB - BACKGROUND: Adoption of robotics in general surgery has expanded but there is no mandatory national standardized curriculum for general surgery residents (GSR). METHODS: A survey was administered to all GSRs in 2014 addressing future practice and robotic experience. A non-mandatory robotic curriculum was available for residents to train. Compliance was assessed. In 2016, the same survey was re administered. Barriers to completing the curriculum were identified. RESULTS: Interest in improving robotic skills remained high (2014 = 97.8% vs 2016 = 95.9%, p = 0.608), and the majority planned to incorporate robotics into future practice (77.8% vs 69.4%; p = 0.358). Only 11 residents (18%) voluntarily completed the curriculum while 36 (60%) started but did not complete. A trend toward increased procedure participation was seen (60.0%-77.6%, p = 0.066). The perceived barriers to completion of the curriculum were length of time required (80%) and lack of access to a simulator (60%). CONCLUSIONS: A structured robotic training curriculum that is non-mandatory is insufficient in helping residents gain fundamental robotic skills. PMID- 29174165 TI - The negative impact of understaging rectal cancer patients. AB - BACKGROUND: Neo-adjuvant chemoradiation followed by surgery and adjuvant therapy is standard treatment of clinical node positive rectal cancer. Understaging leads to delay in treatment with possible detrimental results. This study analyses effects of understaging stage III rectal cancer on long-term outcomes. METHODS: A consecutive series of patients, operated on in MGH between 2004 and 2015 was included. Outcomes of non-neoadjuvantly treated clinical stage I patients who turned out to have pathological stage III disease and neoadjuvantly treated clinical stage III patients were retrospectively reviewed. The latter group was subdivided into patients who had persistent nodal disease (ypN+) and patients without positive lymph nodes after neoadjuvant treatment (ypN0). RESULTS: Of the 204 included patients, 30 had unexpected nodal disease on pathology. Clinical stage I-patients had higher rates of local recurrence, and rectal cancer and overall mortality than ypN0-patients. CONCLUSION: Understaging stage III rectal cancer led to poorer oncologic outcomes, when compared to patients without positive lymph nodes on pathology after neoadjuvant. Future research should focus on identifying patients with treatment susceptible lymph node involvement. PMID- 29174166 TI - Pre-simulation orientation for medical trainees: An approach to decrease anxiety and improve confidence and performance. AB - BACKGROUND: We assessed the effect of basic orientation to the simulation environment on anxiety, confidence, and clinical decision making. METHODS: Twenty four graduating medical students participated in a two-week surgery preparatory curriculum, including three simulations. Baseline anxiety was assessed pre course. Scenarios were completed on day 2 and day 9. Prior to the first simulation, participants were randomly divided into two groups. Only one group received a pre-simulation orientation. Before the second simulation, all students received the same orientation. Learner anxiety was reported immediately preceding and following each simulation. Confidence was assessed post-simulation. Performance was evaluated by surgical faculty. RESULTS: The oriented group experienced decreased anxiety following the first simulation (p = 0.003); the control group did not. Compared to the control group, the oriented group reported less anxiety and greater confidence and received higher performance scores following all three simulations (all p < 0.05). CONCLUSIONS: Pre-simulation orientation reduces anxiety while increasing confidence and improving performance. PMID- 29174167 TI - Progress in the diagnosis and management of adolescent endometriosis: an opinion. AB - Increasing evidence indicates that early onset endometriosis (EOE), starting around menarche or early adolescence, may have an origin different from the adult variant, originating from neonatal uterine bleeding (NUB). This implies seeding of naive endometrial progenitor cells into the pelvic cavity with NUB; these can then activate around thelarche. It has its own pathophysiology, symptomatology and risk factors, warranting critical management re-evaluation. It can also be progressive, endangering future reproductive capacity. This variant seems to be characterized by the presence of ovarian endometrioma. Today, the diagnosis of endometriosis in young patients is often delayed for years; if rapidly progressive, it can severely affect pelvic organs, even in the absence of serious symptoms. Given the predicament, great attention must be paid to symptomatology that is often non-specific, justifying a search for new, simple, non-invasive markers of increased risk. Better use of modern imaging techniques will aid considerably in screening for the presence of EOE. Traditional laparoscopy should be limited to cases in which imaging gives rise to suspicion of severity and a stepwise, minimally invasive approach should be used, followed by medical treatment to prevent recurrence. In conclusion, EOE represents a condition necessitating early diagnosis and stepwise management, including medical treatment. PMID- 29174168 TI - Advanced glycation end product concentrations in follicular fluid of women undergoing IVF/ICSI with a GnRH agonist protocol. AB - The accumulation of advanced glycation end products (AGE) is associated with ovarian dysfunction. This study examines whether the accumulation of AGE in follicular fluid affects ovarian responsiveness and embryo quality during IVF/intracytoplasmic sperm injection (IVF/ICSI) with a gonadotrophin-releasing hormone (GnRH) agonist protocol. The levels of AGE in follicular fluid were measured in 127 women undergoing IVF/ICSI in GnRH agonist cycles. Plasma hormones were also measured. Embryos were graded using standard approaches. There were inverse associations between follicular fluid AGE concentration and number of oocytes retrieved, number of fertilized oocytes, number of high-quality embryos, fertilization rate and high-quality embryo rate, adjusted for potential confounders. AGE concentration in follicular fluid was significantly higher in women with an ovarian response below the target (<7 oocytes) compared with those reaching the target (7-15 oocytes) or above the target (>15 oocytes). The cut-off value of 15.3 ug/ml for follicular fluid AGE showed 84.6% sensitivity and 55.5% specificity in evaluating the response to ovarian stimulation as below the target. The results suggest that ovarian responsiveness and embryo quality are related to intraovarian exposure to AGE.

PMID- 29174170 TI - Kinsbourne syndrome associated with cryptococcosis infection. PMID- 29174171 TI - Helicobacter pylori infection is associated with an increased risk of Parkinson's disease: A population-based retrospective cohort study. AB - BACKGROUND: Several studies have evaluated the association of Parkinson's disease with Helicobacter pylori (HP) infection, although no cohort studies have evaluated this association among the general population. OBJECTIVE: This study aimed to investigate the risk of Parkinson's disease after HP infection in the general Taiwanese population. METHODS: This study of Taiwanese health insurance data (2000-2012) evaluated 9105 cases of HP infection and 9105 controls matched with propensity scoring. Univariate and multivariate Cox proportional hazards regression models were used to assess the risk of subsequent Parkinson's disease. RESULTS: We observed 64 cases of Parkinson's disease in the HP infection group (1.7/1000 person-years), and 25 cases in the control group (0.7/1000 person years). Overall, there was a significantly higher risk of Parkinson's disease in the HP infection group (adjusted hazard ratio [aHR]: 2.29, 95% confidence interval [CI]: 1.44-3.66). HP infection was significantly associated with an increased risk of Parkinson's disease among individuals who were >=60 years old (aHR: 2.53, 95% CI: 1.47-4.35), but not among those <60 years old (aHR: 1.86, 95% CI: 0.69-4.98). Furthermore, HP infection was associated with an increased risk of Parkinson's disease among both men (aHR: 2.14, 95% CI: 1.15-3.96) and women (aHR: 2.84, 95% CI: 1.37-5.89). Nonetheless, eradication therapy was not significantly associated with the risk of Parkinson's disease (aHR: 1.07, 95% CI: 0.63-1.82). CONCLUSION: Although HP infection was associated with an increased risk of Parkinson's disease, eradication therapy did not ameliorate this association. Further research is needed to explore the underlying biological mechanisms. PMID- 29174172 TI - Juvenile-onset parkinsonism with pyramidal signs due to compound heterozygous mutations in the F-Box only protein 7 gene. AB - BACKGROUND: Juvenile-onset parkinsonism is often caused by genetic factors. Mutations in several autosomal genes, including the F-box only protein 7 (FBXO7) gene, have been found in patients suffering from juvenile-onset parkinsonism with pyramidal signs. Only five types of FBXO7 mutations have been described. Here, we present a case report about a Chinese patient presenting with juvenile-onset parkinsonism likely caused by FBXO7 mutations. METHODS: The patient was a 32-year old Chinese male. DNA samples were extracted from the patient and his parents. Exons in parkinsonism-related genes were amplified and sequenced. RESULTS: The patient began experiencing a progressive involuntary tremor in his left hand at 16 years of age, which was followed by the development of gait dysfunction, dysarthria, and rapid eye movement sleep behavior disorder. A neurological examination of the patient revealed cogwheel rigidity, bradykinesia, static and postural tremor and bilateral Babinski signs. The patient responded to dopaminergic therapies but was affected by psychiatric side effects. Further genetic analysis of the patient and his parents revealed compound heterozygous mutations of the FBXO7 gene (NM_012179.3) in the patient (a nonsense c.1408G > T (p.E470X) mutation and a missense c.152A > G (p.N51S) mutation coming from the patient's mother and father, respectively). CONCLUSIONS: This is the first case harboring FBXO7 mutations that presented with juvenile-onset parkinsonism in the Chinese population. PMID- 29174174 TI - Significant association of rheumatoid arthritis-related inflammatory markers with non-surgical periodontal therapy. AB - BACKGROUND/PURPOSE: Chronic periodontitis (CP) and rheumatoid arthritis (RA) are the most common chronic inflammatory diseases and their immunopathogenesis is similar. The aim of this study was to evaluate the effect of non-surgical periodontal treatment on the serum levels of RA-related inflammatory markers in patients with chronic periodontitis. METHODS: Thirty-one Taiwanese adults with CP were included. Demographics and periodontal parameters, including probing depth, clinical attachment level, and number of remaining teeth in the oral cavity, were recorded. All subjects received non-surgical periodontal treatment such as scaling and subgingival root planing. Serum samples were collected before and after the treatment. Serum levels of anti-citrullinated protein antibodies (ACPA), rheumatoid factor, tumor necrosis factor-alpha (TNF-alpha), C-reactive protein, interleukin-1beta (IL-1beta), and Interleukin-6 (IL-6) were measured using an enzyme-linked immunosorbent assay. RESULTS: Non-surgical periodontal treatment significantly reduced the serum ACPA (p = 0.015) and TNF-alpha levels (p = 0.026) in CP patients, particularly in patients with generalized CP. Furthermore, there was a significant and positive correlation between the number of extracted teeth and the reduction in the serum ACPA (p = 0.05) and IL-1beta levels (p = 0.029) after non-surgical periodontal treatment. CONCLUSION: Non surgical periodontal therapy may aid in the control of RA-related inflammatory markers in patients with CP. A large-scale study with well-defined populations is needed to clarify the benefit of non-surgical periodontal therapy. PMID- 29174173 TI - Spatiotemporal Control of Acetyl-CoA Metabolism in Chromatin Regulation. AB - The epigenome is sensitive to the availability of metabolites that serve as substrates of chromatin-modifying enzymes. Links between acetyl-CoA metabolism, histone acetylation, and gene regulation have been documented, although how specificity in gene regulation is achieved by a metabolite has been challenging to answer. Recent studies suggest that acetyl-CoA metabolism is tightly regulated both spatially and temporally to elicit responses to nutrient availability and signaling cues. Here we discuss evidence that acetyl-CoA production is differentially regulated in the nucleus and cytosol of mammalian cells. Recent findings indicate that acetyl-CoA availability for site-specific histone acetylation is influenced through post-translational modification of acetyl-CoA producing enzymes, as well as through dynamic regulation of the nuclear localization and chromatin recruitment of these enzymes. PMID- 29174175 TI - Imaging appearances of hepatic tuberculosis: experience with 12 patients. AB - AIM: To review computed tomography (CT), ultrasound (US), magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiogram (PTC) appearances and their diagnostic value in hepatic tuberculosis. MATERIALS AND METHODS: The imaging studies for 12 patients with biopsy-proven hepatic tuberculosis from January 2012 till March 2014 were reviewed retrospectively. These cases were confirmed via ultrasound-guided biopsy. RESULTS: The patients were aged 24-72 years. Four patients had parenchymal tuberculosis only and eight patients had mixed parenchymal and biliary duct involvement. The parenchymal tuberculosis patients showed poorly enhancing, hypodense nodules on CT with central calcification and adjacent dilated intrahepatic ducts. Most patients had multiple lesions except for two patients with a single lesion. The size of the lesions ranged from 0.5 to 6 cm. Seven patients with biliary duct involvement showed a hilar strictures involving the intrahepatic ducts and common bile duct. Nine of the patients showed hilar stricture with atrophy of the ipsilateral lobe of the liver and compensatory hypertrophy of the contralateral lobe. Hepatolithiasis was seen in five patients. Tuberculous lung involvement was seen in seven patients. CONCLUSION: The presence of calcified and hypodense nodules with biliary duct dilatation associated with lobar atrophy were the most consistent features of hepatic tuberculosis, especially in the presence of active lung disease.

PMID- 29174177 TI - Long-term outcomes of six patients after partial internal biliary diversion for progressive familial intrahepatic cholestasis. AB - BACKGROUND: Partial internal biliary diversion (PIBD) is an alternative approach for the treatment of devastating pruritus in patients with progressive familial intrahepatic cholestasis (PFIC). In these patients quality of life can be improved and progression of liver disease can be delayed while waiting for liver transplantation. The aim of our study was to evaluate six patients with PFIC who have undergone PIBD in long-term follow-up. METHODS: Retrospective review of the records of six patients who underwent PIBD for PFIC between 2008 and 2010 was conducted to evaluate age, growth, clinical and laboratory studies for long-term outcome. RESULTS: Serum postoperative bile acid levels were reduced from a mean 340.1MUmol/L (range 851-105) preoperatively to a mean of 96.3MUmol/L at postoperative fifth year. The difference between pre- and postoperative bile acid levels was statistically significant (p=0.018). AST decreased from 79.1U/L (range 43-150U/L) to 64.6U/L (range 18-172U/L), ALT decreased from 102.8U/L (range 35 270U/L) to 84.6U/L and total bilirubin decreased from 2.9MUmol/L (range 0.35 6.4MUmol/L) to 1.53MUmol/L (range 0.3-2.4). Again, the decrease in total bilirubin levels was significant (p=0.043). Pruritus was diminished from a mean of +4 (range 4-4) preoperatively to a mean of +2 (4-0). One patient who underwent liver transplantation owing to relapsing pruritus died from postoperative sepsis in the early postoperative period at the fifth year after PBID. Five symptom-free patients have not required liver transplantation at a mean period of 6.1+/ 0.83years (5.1-7.0years) follow-up. CONCLUSION: PBID is an effective surgical procedure in the long-term and can delay the need for liver transplantation in children with PFIC by reducing jaundice and pruritus. PMID- 29174178 TI - Radiation burden of pediatric ultrasound-guided percutaneous central venous access devices: A prospective cohort study. AB - : Permanent central venous access is essential for the management of many pediatric patients. Knowing the amount of ionizing radiation used during the insertion of these devices is important. Our aim was to identify the radiation used in percutaneous insertion of central venous access devices, and to correlate radiation exposure to patient weight. METHODS: Data was prospectively collected during a 12-month period from August 2015 to August 2016 on all ultrasound-guided percutaneous central venous access device insertions. An image intensifier was used in all insertions with data on radiation dose and screening time extracted, when available. The total radiation dose was measured in mGym2 and the total radiation time in seconds. A p-value <0.05 was used to denote statistical significance. RESULTS: A total of 145 central venous access devices were inserted (82 portacaths, 43 double lumen lines, 16 single lumen lines and 4 hemocaths) in 127 patients (Median Age: 5.5years (Range 0-17); Median Weight 21kg (Range 1.9 100)) with 15 patients requiring multiple insertions over the course of the study. Of these, 88 had data captured for total radiation dose and time used and a further 23 had screening time only recorded. Median radiation dose was 0.00599 mGym2 (range 0.000543-0.148) with a median fluoroscopic screening time of 18s (range 2-479). Median dose was higher for children <10kg compared to larger children, 0.00661 mGym2 (range 0.00202-0.0468) versus 0.005715 mGym2 (range 0.000543-0.148) respectively. Left-sided internal jugular vein (IJV) insertions also had a higher median radiation dose of 0.0091 mGym2 (range 0.00142-0.148 mGym2) versus 0.005245 mGym2 (range 0.000543-0.0285 mGym2) for right-sided IJV insertions. CONCLUSION: The radiation burden to children from percutaneous ultrasound-guided central venous access device insertions is small, in the order of that received during a chest radiograph. Weight<10kg and access of the left IJV are associated with receiving higher doses. STUDY TYPE: Cohort Study (Level of Evidence: II).

PMID- 29174184 TI - Competitive interaction between chronic obstructive pulmonary disease and CHA2DS2 VASc score in predicting incident atrial fibrillation. AB - BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality, and an emerging risk factor for atrial fibrillation (AF). CHADS2 and CHA2DS2-VASc scores are significantly associated with incident AF independently of other risk factors. The aim of this study was to demonstrate a possible interaction between COPD and CHA2DS2-VASc in predicting incident AF. METHODS: This observational prospective cohort study included 4322 Caucasians with cardiovascular risk factors, stratified by CHA2DS2-VASc score (>2 vs <2) and presence/absence of COPD. To detect AF appearance, patients underwent, every 6months, physical examination, standard 12-lead electrocardiogram and routine laboratory tests. RESULTS: COPD prevalence was significantly higher in patients with CHA2DS2-VASc>=2 vs CHA2DS2-VASc<2 category (13.3% vs 10.5%, P=0.009). During the follow-up, 589 cases of AF were documented (3.8 events/100 patients-year). COPD+ showed a significantly higher incidence of AF vs COPD- patients (17.4 vs 8.4 events/100 patients-year, P<0.0001). In Cox regression models both CHA2DS2 VASc score (HR=4.70, 95% CI=3.63-6.08) and COPD (HR=2.04, 95% CI=1.69-2.48) significantly predicted the incidence rate of AF; this was also confirmed introducing the two variables into the same Cox model. A significant competitive interaction between CHA2DS2-VASc and COPD was found in a Cox model in patients with CHA2DS2-VASc<2 (HR=8.45, 95% CI=5.20-13.74) than in those with CHA2DS2 VASc>=2. CONCLUSIONS: COPD is an independent and strong predictor of incident AF. The presence of COPD increases the HR for incident AF about five times in patients with CHA2DS2VASc score<2, while the coexistence of a CHA2DS2Vasc score>=2 minimizes the prognostic significance of COPD. PMID- 29174185 TI - Specific motor patterns of arousal disorders in adults: a video-polysomnographic analysis of 184 episodes. AB - OBJECTIVE: To compile an objective accurate description of the motor patterns of adult arousal disorders (ADs). METHODS: We reviewed 59 nocturnal video polysomnographic (VPSG) recordings of 30 adult patients (>15 years) with a history of sleepwalking (SW). We scrutinized the semeiology of all 184 episodes recorded, classifying them into three groups according to three semeiological motor patterns characterized by increasing intensity and complexity: simple arousal movements (pattern I), characterized by head flexion/extension, head flexion/extension and limb movement or head flexion/extension and partial trunk flexion/extension; rising arousal movements (pattern II), characterized by a complete trunk flexion with patient sitting up in bed; and complex arousal with ambulatory movements (pattern III) characterized by SW. The VPSG recordings were compared to those of 10 healthy controls. RESULTS: AD patients presented with 169 pattern I, 37 pattern II, and nine pattern III episodes. Pattern I developed into pattern II in 17 cases and into pattern II followed by pattern III in five patients. Pattern II developed into pattern III in four patients. Onset was abrupt in 55% of the episodes. Episodes lasted a mean (+/-standard deviation) of 33 +/- 35 s. Movements tended to halt temporarily during 72% of the episodes. We recorded 248 movements during sleep in the healthy controls, none of whom presented with AD patterns. CONCLUSION: We identified three specific motor patterns in AD patients not previously reported and not observed in healthy controls. Identification of these patterns could be important for diagnosis and serve as the basis for a new definition of AD in adults.

PMID- 29174187 TI - Risk of cancer death by comorbidity severity and use of adjuvant chemotherapy among women with locoregional breast cancer. AB - OBJECTIVES: To examine the associations of comorbidity and chemotherapy with breast cancer- and non-breast cancer-related death. MATERIALS AND METHODS: Included were women with invasive locoregional breast cancer diagnosed in 2004 from seven population-based cancer registries. Data were abstracted from medical records and verified with treating physicians when there were inconsistencies and missing information on cancer treatment. Comorbidity severity was quantified using the Adult Comorbidity Evaluation 27. Treatment guideline concordance was determined by comparing treatment received with the National Comprehensive Cancer Network guidelines. Kaplan-Meier method and multivariable Cox proportional hazards regressions were employed for statistical analyses. RESULTS: Of 5852 patients, 76% were under 70years old and 69% received guideline concordant adjuvant chemotherapy. Comorbidity was more prevalent in women age 70 and older (79% vs. 51%; p<0.001). After adjusting for tumor characteristics and treatment, severe comorbidity burden was associated with significantly higher cancer-related mortality in older patients (Hazard Ratio [HR]=2.38, 95% CI 1.08-5.24), but not in younger patients (HR=1.78, 95% CI 0.87-3.64). Among patients receiving guideline adjuvant chemotherapy, cancer-related mortality was significantly higher in older patients (HR=2.35, 95% CI 1.52-3.62), and those with severe comorbidity (HR=3.79, 95% CI 1.72-8.33). CONCLUSIONS: Findings suggest that, compared to women with no comorbidity, patients with breast cancer age 70 and older with severe comorbidity are at increased risk of dying from breast cancer, even after adjustment for adjuvant chemotherapy and other tumor and treatment differences. This information adds to risk-benefit discussions and emphasizes the need for further study of the role for adjuvant chemotherapy in these patient groups. PMID- 29174188 TI - Impact of Radiation Dose Reduction in Abdominal Computed Tomography on Diagnostic Accuracy and Diagnostic Performance in Patients with Suspected Appendicitis: An Intraindividual Comparison. AB - RATIONALE AND OBJECTIVES: To determine the intraindividual impact of radiation dose reduction in abdominal computed tomography (CT) on diagnostic performance in patients with suspected appendicitis. MATERIALS AND METHODS: This study was approved by the institutional review board. Seventy-five patients who underwent standard contrast-enhanced abdominal CT for suspected appendicitis between 2004 and 2009 were retrospectively included. Low-dose CT reconstructions with 75%, 50%, and 25% of the original radiation dose level were generated by applying realistic reduced-dose simulation. Two blinded, independent readers assessed image quality, signal-to-noise ratio, and diagnostic confidence on each dataset. Diagnostic accuracy for detection of appendicitis and complications were calculated for each reader. Paired univariate tests were used to determine intraindividual differences. RESULTS: Among 75 subjects included in the analysis (57% female, mean age: 41 +/- 18 years), the prevalence of histopathologically confirmed appendicitis was 59%. Signal-to-noise ratio and subjective image quality of 50% and 25% reduced-dose CTs were significantly lower than the reference datasets (all P < .005). Appendicitis was correctly identified in all reference and low-dose datasets (sensitivity: 100%, negative predictive value: 100%). Presence of complications was correctly detected in all reference, 75%, and 50% datasets, but was decreased in 25% datasets (sensitivity: 77.8% and negative predictive value: 97.4%). Diagnostic confidence was high for original and 75% datasets, but significantly lower for 50% and 25% datasets (P < .001). CONCLUSIONS: Our results indicate that diagnostic accuracy in abdominal CT acquisitions acquired at 75% and 50% of radiation dose is maintained in patients with suspected appendicitis, whereas further reduction of radiation exposition is associated with decreased diagnostic performance. PMID- 29174189 TI - Regional Heterogeneity of Lobar Ventilation in Asthma Using Hyperpolarized Helium 3 MRI. AB - RATIONALE AND OBJECTIVES: To determine lobar ventilation patterns in asthmatic lungs with hyperpolarized 3He magnetic resonance imaging (HP 3He MRI). MATERIALS AND METHODS: Eighty-two subjects (14 normal, 48 mild-to-moderate asthma, and 20 severe asthma) underwent HP 3He MRI, computed tomography (CT), and pulmonary function testing. After registering proton to 3He images, we segmented the lungs from proton MRI and further segmented the five lung lobes (right upper lobe [RUL], right middle lobe [RML], and right lower lobe [RLL]; left upper lobe and left lower lobe [LLL]) by referring to the lobar segmentation from CT. We classified the gas volume into four signal intensity levels as follows: ventilation defect percent (VDP), low ventilation percent, medium ventilation percent, and high ventilation percent. The local signal intensity variations in the ventilated volume were estimated using heterogeneity score (Hs). We compared each ventilation level and Hs measured in the whole lung and lobar regions across the three subject groups. RESULTS: In mild-to-moderate asthma, the RML and RUL showed significantly greater VDP than the two lower lobes (RLL and LLL) (P <= .047). In severe asthma, the pattern was more variable with the VDP in the RUL significantly greater than in the RLL (P = .026). In both asthma groups, the lower lobes (RLL and LLL) showed significantly higher high ventilation percent and Hs compared to the three upper lobes (all P <= .015). CONCLUSIONS: In asthma, the RML and RUL showed greater ventilation abnormalities, and the RLL and LLL were more highly ventilated with greater local heterogeneity. These findings may facilitate guided bronchoscopic sampling and localized airway treatment in future studies. PMID- 29174190 TI - Communicating Radiology Test Results: Are Our Phone Calls Excessive, Just Right, or Not Enough? AB - RATIONALE AND OBJECTIVES: This study aimed to determine the preferences of radiology and referring provider residents regarding direct communication of radiology test results. METHODS: This Health Insurance Portability and Accountability Act-compliant quality improvement effort was exempt from institutional review board oversight. An anonymous survey was emailed to 44 radiology residents and 364 referring resident providers who routinely provide or receive direct communication of test results at our quaternary care medical center. The survey focused on the frequency, indication, clinical utility, and methods of direct communication of radiology results. Proportions were compared to chi-square or Fisher exact test. RESULTS: The response rates were 86% (37 of 43) (radiology) and 41% (151 of 364) (referring providers). Approximately half of radiology residents (49% [18 of 37]) thought the frequency of direct verbal communication was excessive, and none (0 of 37) thought more communication was needed. In contrast, only 1.3% (2 of 151; P < .001) of referring providers felt the frequency was excessive, and 24% (36 of 151; P < .001) desired more. The majority (66% [100 of 151]) of referring providers felt phone calls from radiologists often or always added value beyond a timely radiology report, and 59% (44 of 74) felt it is the radiologist's responsibility to call about abnormal findings. Furthermore, 83% (125 of 151) of referring providers preferred to receive a phone call about non-emergent unexpected findings, although preferences varied for various example abnormalities. For outpatients with non-emergent unexpected findings, most providers (90% [64 of 71]) prefer written communication rather than a phone call. CONCLUSIONS: Referring providers prefer direct communication of radiology results, even for non-urgent unexpected findings, whereas radiology residents prefer less direct communication and are more likely to consider radiologist-to-provider communication superfluous. PMID- 29174191 TI - Expanding the Definition of a Benign Renal Cyst on Contrast-enhanced CT: Can Incidental Homogeneous Renal Masses Measuring 21-39 HU be Safely Ignored? AB - RATIONALE AND OBJECTIVE: We aimed to determine the frequency and clinical significance of homogeneous renal masses measuring 21-39 Hounsfield units on contrast-enhanced computed tomography (CT). METHODS: Subjects 40-69 years old undergoing portal-venous-phase contrast-enhanced abdominal CT from January 1, 2006 to December 31, 2010 with slice thickness <=5 mm and no prior CT or magnetic resonance imaging were identified (n = 1387) for this institutional review board approved retrospective cohort study. Images were manually reviewed by three radiologists in consensus to identify all circumscribed homogeneous renal masses (maximum of three per subject) >=10 mm with a measured attenuation of 21-39 Hounsfield units. Exclusion criteria were known renal cancer or imaging performed for a renal indication. The primary outcome was retrospective characterization as a clinically significant mass, defined as a solid mass, a Bosniak IIF/III/IV mass, or extirpative therapy or metastatic renal cancer within 5 years' follow up. RESULTS: Eligible masses (n = 74) were found in 5% (63/1387) of subjects. Of those with a reference standard (n = 42), none (0% [95% CI: 0.0%-8.4%]) were determined to be clinically significant. CONCLUSION: Incidental renal masses on contrast-enhanced CT that are homogeneous and display an attenuation of 21-39 Hounsfield units are uncommon in patients 40-69 years of age, unlikely to be clinically significant, and may not need further imaging evaluation. If these results can be replicated in an independent and larger population, the practical definition of a benign cyst on imaging may be able to be expanded. PMID- 29174192 TI - Implementation of an antimicrobial stewardship program for patients with febrile neutropenia. AB - BACKGROUND: We aimed to describe the effectiveness of our standardized protocol for febrile neutropenia (FN), which was targeted to minimize unintended outcomes and reduce antimicrobial consumption. METHODS: The study was performed in a private hospital with 300 beds. We included all adult hematologic and oncologic cancer inpatients admitted between January 1, 2015-December 31, 2015, and January 1, 2016-May 31, 2017. The outcomes of the study were fatality, infections, and adherence to the antimicrobial stewardship program (ASP). RESULTS: We included 152 FN attacks of 95 adult inpatients from hematology and oncology wards; of these, 43% were women, and the median age was 57 years. The case fatality rate was 30% in the pre-ASP period and decreased to 11% in the post-ASP period (P = .024). The appropriate adding or changing (P = .006) and appropriate continuation or de-escalation or discontinuation of antimicrobials improved (P < .001). In the post-ASP period, Staphylococcus spp infections (from 22% to 8%, P = .02) and gram negative infections decreased (from 43% to 20%, P = .003). In the multivariate analysis, appropriate continuation or de-escalation or discontinuation was increased in the post-ASP period (odds ratio [OR], 4.3; 95% confidence interval [CI], 1.82-10.41; P = .001), and gram-positive infections were decreased (OR, 0.32; 95% CI, 0.11-0.95, P = .041). Vancomycin and fluoroquinolone use decreased significantly. CONCLUSIONS: After implementation of the ASP, the case fatality rate among the patients with FN decreased. Appropriate antimicrobial use increased and overall antimicrobial consumption was reduced. Bacterial infections and Candida infections decreased. PMID- 29174193 TI - Environmental and body contamination from cleaning vomitus in a health care setting: A simulation study. AB - BACKGROUND: Environmental service workers may be exposed to pathogens during the cleaning of pathogen-containing bodily fluids. METHODS: Participants with experience cleaning hospital environments were asked to clean simulated, fluorescein-containing vomitus using normal practices in a simulated patient room. Fluorescein was visualized in the environment and on participants under black lights. Fluorescein was quantitatively measured on the floor, in the air, and on gloves and shoe covers. RESULTS: In all 21 trials involving 7 participants, fluorescein was found on the floor after cleaning and on participants' gloves. Lower levels of floor contamination were associated with the use of towels to remove bulk fluid (rho = -0.56, P = .01). Glove contamination was not associated with the number or frequency of contacts with environmental surfaces, suggesting contamination occurs with specific events, such as picking up contaminated towels. Fluorescein contamination on shoe covers was measured in 19 trials. Fluorescein was not observed on participants' facial personal protective equipment, if worn, or faces. Contamination on other body parts, primarily the legs, was observed in 8 trials. Fluorescein was infrequently quantified in the air. CONCLUSIONS: Using towels to remove bulk fluid prior to mopping is part of the recommended cleaning protocol and should be used to minimize residual contamination. Contamination on shoes and the floor may serve as reservoirs for pathogens.

AB - Central neuropathic pain (CNP) is common and disabling among patients with multiple sclerosis (MS). The pathological mechanisms underlying CNP in MS are not well understood. We explored whether NGF is implicated in the pathogenesis of CNP in MS. We measured NGF concentration in the CSF of 73 patients affected by MS, 15 with and 58 without CNP and 14 controls. We found increased levels of NGF in the CSF of patients with CNP compared to patients without and to controls. This finding supports the hypothesis that NGF plays a role in MS related CNP.

AB - To better understand brain dysfunction during sepsis, cerebral arterial blood flow was assessed with Phase Contrast Magnetic Resonance Imaging, perfusion with Arterial Spin Labeling and structure with diffusion-weighted Magnetic Resonance Imaging in rats after intraperitoneal administration of bacterial lipopolysaccharides. Although cerebral arterial flow was not altered, perfusion of the corpus callosum region and diffusion parallel to its fibers were higher after lipopolysaccharide administration as compared to saline injection. In parallel, lipopolysaccharide induced perivascular immunoglobulin-immunoreactivity in white matter. These findings indicate that systemic inflammation can result in increased perfusion, blood-brain barrier breakdown and altered water diffusion in white matter.

PMID- 29174197 TI - Comparison of cardiac measurements by multi-detector computed tomography angiography and transthoracic echocardiography in English bulldogs. AB - INTRODUCTION: Transthoracic echocardiography (TTE) is the primary tool for the assessment of cardiac structure and function in dogs but is challenging in English bulldogs due to dorsoventral compression of the thorax, obesity, and narrow intercostal spaces. Multi-detector computed tomography angiography (CTA) may overcome the conformational obstacles of cardiac imaging in this breed. ANIMALS: Eleven client-owned English bulldogs. MATERIALS AND METHODS: Prospective clinical trial with paired analysis of TTE and CTA studies. RESULTS: Eight of the 25 linear cardiac dimensional measurements were significantly different between TTE and CTA (p<0.033). Intraobserver agreement was strong with average coefficients of variation (CV) of 5.34% for TTE and 2.50% for CTA. Interobserver agreement CV averaged 6.5% for TTE and 8.75% CTA. Ejection fraction, stroke volume, and end-systolic volume were significantly different between modalities (all p<0.002). No significant difference was present between end-diastolic volume for TTE compared with CTA. DISCUSSION: High-quality cardiac angiographic studies were accomplished using CTA without the use of general anesthesia in English bulldogs. Multi-detector computed tomography angiography and TTE are not interchangeable modalities in the clinical setting. CONCLUSION: Multi-detector-CT ECG-gated cardiac angiography is possible in sedated, non-intubated English bulldogs. Differences were found between some cardiac dimensions as measured by TTE in the awake dog and compared with sedated CTA, indicating the two methodologies are not equivalent. Sedated, non-intubated CTA yielded high-quality imaging with strong intraobserver and interobserver measurement repeatability in English bulldogs. PMID- 29174198 TI - Management of benign papilloma without atypia diagnosed at ultrasound-guided core needle biopsy: Scoring system for predicting malignancy. AB - BACKGROUND: The management of benign intraductal papilloma diagnosed on core needle biopsy (CNB) remains unclear. This study was designed to evaluate factors predicting malignancy in patients diagnosed with benign papilloma without atypia at ultrasound-guided CNB and to develop a scoring system predicting malignancy based on clinical, radiological and pathological factors on further excisional biopsy. METHODS: The study enrolled patients diagnosed with benign papillomas (including benign and atypical papillary lesions) at CNB. Multivariate analysis was used to identify relevant clinical, radiological and pathological factors that may predict malignancy. RESULTS: A total of 520 CNBs were diagnosed with benign or atypical papilloma. Of these, 452 were benign papilloma without atypia. Of the 250 lesions subsequently excised surgically from 234 women, 17 (6.8%) were diagnosed with malignancy. Multivariate analysis revealed that bloody nipple discharge, size on imaging >=15 mm, BI-RADS>=4b, peripheral location and palpability were independent predictors of malignancy. A scoring system was developed based on logistic regression models and beta coefficients for each variable. The area under the ROC curve was 0.947 (95% CI: 0.913-0.981, p < 0.001) and a negative predictive value was 100%. In a validation set of 62 patients, an area under the ROC curve was 0.926 (95% CI: 0.857-0.995, p < 0.001). CONCLUSIONS: A scoring system predicting malignancy in patients diagnosed by CNB with benign papilloma without atypia was developed. This system was able to identify a subset of patients with lesions likely to be benign, indicating that imaging follow-up rather than surgical excision may be appropriate.

PMID- 29174200 TI - Group 2: Adrenal insufficiency: screening methods and confirmation of diagnosis. AB - A diagnosis of adrenal insufficiency should be suspected in the presence of a number of non-specific symptoms (fatigue, anorexia, weight loss, hypotension, hyponatremia and hyperkalemia amongst adrenal causes of insufficiency). The diagnosis should be considered in case of pituitary disease or a state of shock. Treatment should be commenced immediately without waiting for confirmation from biochemical tests, which rely on cortisol level at 8am (expected to be low) and on ACTH level (expected to be high in the case of primary adrenal insufficiency). If these tests are inconclusive, a Synacthen test should be carried out. The threshold limits are provided as a guide. Low plasma cortisol and normal to low plasma ACTH indicates a pituitary origin for the deficiency. In this situation, the Synacthen test can give a false normal result, and if this adrenal insufficiency is strongly suspected, an insulin hypoglycemia test or metyrapone (Metopirone(r)) test should be carried out. In children younger than 2yr, hypoglycemia, dehydration and convulsions are frequently observed and in young girls, virilization is suspect of congenital adrenal hyperplasia . The circadian rhythm of cortisol is not present until after 4months of age and the Synacthen test is the only one that is feasible. In children older than 2yrs, the signs and diagnostic methods are the same as in the adult. Cessation of corticosteroid treatment is a frequent circumstance however there is little published data and no evidence for definitive guidelines. After ceasing a short period of corticosteroid treatment, patient education is all that is required. After longer treatment, consensus leaves the choice up to the physician, between educating the patient and prescribing hydrocortisone in case of stress, or prescribing low daily dose hydrocortisone and evaluating the ACTH axis over time until normal function is recovered.

AB - Graduate entry nursing programs designed for individuals with prior degrees in other disciplines are becoming increasingly popular internationally. They provide entry into nursing for people with unique skill-sets. Yet, little is known about why these individuals choose career change into nursing and what they expect from their new careers. This component of a larger study sought to explore graduate entry nursing students' short and longer term career intentions on commencement of their courses. A cross-sectional survey was used. Descriptive frequencies were used to analyse demographic data, while summative content analysis was used with the open-ended questions. Participants were drawn from eight cohorts of commencing students from enrolled in one graduate entry masters program in Australia between 2009 and 2015. Content analysis identified three main categories: professional role, work location, and work context. Longer term responses were categorised under four categories: professional role, work location, work context and personal and professional goals. Many students had clear directions about their future nursing careers. On graduation, many envisioned working in advanced roles or in clinical specialty areas, primarily in hospital settings. However, in the longer term, there was diversity among with many envisaging work outside traditional hospital settings, and some in other health disciplines. PMID- 29174203 TI - Phase I/II Trial of Combined Pegylated Liposomal Doxorubicin and Cyclophosphamide in Metastatic Breast Cancer. AB - INTRODUCTION: Doxorubicin in combination with cyclophosphamide is active in breast cancer; however, its use in metastatic cancer is limited owing to cardiotoxicity. Pegylated liposomal doxorubicin (PLD) was formulated to decrease the toxicity of conventional doxorubicin. We evaluated the safety and efficacy of PLD with metronomic oral cyclophosphamide. PATIENTS AND METHODS: We conducted a single-arm open-label phase I/II study of PLD and oral cyclophosphamide in patients with metastatic breast cancer. In phase I, 3 escalating doses of PLD were planned (30, 35, and 40 mg/m2) with cyclophosphamide (60 mg/m2 orally daily) to determine the maximum tolerated dose (MTD). In phase II, the MTD of PLD in combination of oral cyclophosphamide was used to assess the primary endpoint of overall clinical response rate and secondary endpoints of progression-free survival, overall survival, and adverse events. RESULTS: Thirty patients were enrolled in the study (n = 6 in phase I and n = 24 in phase II). The MTD of PLD from phase I was 30 mg/m2. The median progression-free and overall survival for the entire cohort were 6.4 months (95% confidence interval, 3.9 months to N/A) and 18.7 months (95% confidence interval, 15.1-31.5 months), respectively. A total of 21 (75%) patients had clinical benefit, including 6 (21%) patients with partial response and 15 (54%) patients with stable disease. The majority of toxicities were uncomplicated myelosuppression, and no infection or febrile neutropenia were noted in any patient. CONCLUSION: PLD in combination with daily oral cyclophosphamide is an active and tolerable regimen in metastatic breast cancer.

PMID- 29174205 TI - The Current State of Radiology Call Assistant Triage Programs Among US Radiology Residency Programs. AB - RATIONALE AND OBJECTIVES: Given increasing volume and workflow interruptions in radiology, we sought to identify and characterize radiology call assistant triage (RCAT) programs among US radiology residency programs. MATERIALS AND METHODS: A survey was created using Qualtrics survey software and emailed to all members of the Association of Program Directors in Radiology listserv. A total of 296 active members belong to this listserv, including program directors and assistant program directors. The survey included questions about the existence and specifics of a call triage assistant program. RESULTS: Data were obtained from 88 active members of the Association of Program Directors in Radiology (30% response rate). Of those, 20 programs (23%) have an RCAT program. Triage assistant staffing includes nonmedical or clerical staff (60%), medical students (30%), first-year radiology residents (5%), and technologists (5%). All respondents with RCAT programs report satisfaction with their program and plan to continue. A significant majority (75%) have no plans to change, whereas the remaining 25% are considering program expansion and pay increases. Among residency programs without RCAT programs, none reported termination of their triage program. The most common reasons for not having triage assistants include cost, lack of awareness, differing opinions on utility, and the presence of 24/7 attending coverage. CONCLUSION: Twenty US radiology residency programs report having an RCAT program. All report satisfaction with their program despite different staffing models. RCAT programs may represent an effective measure in limiting interruptions and potentially decreasing interpretative errors made by residents on call.

PMID- 29174207 TI - Detection of the Tram Track Lesion in the Ankle Joint: Comparing 3.0-Tesla Magnetic Resonance Imaging and Arthroscopy. AB - PURPOSE: To show the effectiveness of magnetic resonance imaging (MRI) for the detection of tram track lesions in the ankle compared with ankle arthroscopy. METHODS: We retrospectively assessed all patients who underwent arthroscopic ankle surgery between January 2013 and July 2015. Patients with anterior impingement spurs were included, but those with an osteochondral lesion or arthritis were excluded. Anterior ankle bony spurs on preoperative weight-bearing radiographs were scored using an impingement classification system. The 3.0-tesla MRIs were reviewed for tram track lesions (defined as focal high signal intensity along the talar dome cartilage surface on coronal views) and compared with arthroscopic findings. The cartilage defect grade at arthroscopy was stratified according to the International Cartilage Repair Society (ICRS) grading system. RESULTS: Overall, 175 ankles in 170 patients were evaluated. Tram track lesions were identified on MRI in 14 ankles (8.0%) and at arthroscopy in 16 ankles (9.1%). The overall sensitivity of MRI for the detection of tram track lesions was 87.5% and the specificity was 100%. On plain weight-bearing radiographs, of the 16 patients with confirmed tram track lesions on arthroscopy, 4 patients had grade 1, 2 had grade 2, and 10 had grade 3 impingement spurs. Under the ICRS grading system, 4 patients had grade II, 4 had grade III, and 8 had grade IV cartilage defects at arthroscopy. On MRI, 2 patients had grade II (50% of arthroscopy), 4 had grade III (100% of arthroscopy), and 8 had grade IV defects (100% of arthroscopy). The impingement spur grade showed no significant correlation with the arthroscopic ICRS grade of the tram track lesion (P = .609). CONCLUSION: Tram track lesions can be confidently detected on MRI with high sensitivity and specificity. The impingement spur grade did not correlate with the severity of cartilage injury of the talar dome. LEVEL OF EVIDENCE: Level III, diagnostic evaluation study. PMID- 29174208 TI - Does Azathioprine induce endoscopic and histologic healing in pediatric inflammatory bowel disease? A prospective, observational study. AB - BACKGROUND: The new concept of disease remission for pediatric inflammatory bowel diseases (IBD) implies the achievement of mucosal healing. AIMS: We aimed to evaluate endoscopic and histologic healing in children with Ulcerative Colitis (UC) and Crohn's disease (CD) in clinical remission after 52 weeks of Azathioprine. METHODS: From December 2012 to July 2015 we prospectively enrolled IBD children starting Azathioprine. Enrolled patients in clinical remission underwent colonoscopy after 52 weeks. Macroscopic assessment was described with Mayo score and the simplified endoscopic score for UC and CD, respectively. For microscopic assessment, an average histology score was used. Data on inflammatory markers and fecal calprotectin were also collected. RESULTS: Fourty-seven patients were included in the analysis. Endoscopic healing was detected in 20/26 (76.9%) UC children and 10/21 (47.6%) CD patients. Median Mayo score and simplified endoscopic score were significantly decreased at week 52 (p<0.001; p=0.005). Median average histology score was not significantly different at week 52 in both diseases. Fecal calprotectin was directly correlated with simplified endoscopic score (T0: r=0.4, p=0.05; T52: r=0.5, p=0.01), but not with Mayo score. No correlation was found between endoscopic and histologic scores. CONCLUSIONS: IBD children under Azathioprine reach endoscopic healing, but not histological remission.

AB - OBJECTIVE: To describe the ultrasound (US) evaluation of the cervical, thoracic and lumbar spinal tracts in piglets and to evaluate the feasibility of the ultrasound guided spinal catheter placement in newborn and paediatric piglets. STUDY DESIGN: Prospective experimental study. ANIMALS: A total of two piglet cadavers (age, 7 and 14 days) and eight commercial crossbreed piglets divided into four groups according to age: 7 (P7), 14 (P14), 21 (P21) and 28 (P28) days. METHODS: In the first part of the study an ultrasound examination of the spinal tract was performed in piglet cadavers applying the transverse and the longitudinal approaches in sternal and lateral recumbencies. In the second phase, the piglets were anaesthetized with sevoflurane. A US examination with a 10 MHz linear probe was performed and a spinal catheter was introduced between the spinous processes of L2 and L3 lumbar vertebrae using an in-plane technique and its advancement was monitored with the probe. At the end of procedure, the catheter was removed. The piglets recovered from anaesthesia and were monitored for one week. RESULTS: In phase I the authors identified the paramedian longitudinal approach as the most feasible for spinal structure evaluation in piglets. In phase II, the paramedian longitudinal views enabled a good visualization of the spinal cord and of the catheter advancement up to the cisterna magna in groups P7 and P14. In groups P21 and P28 it was not possible to visualize the neuroaxial structures and the spinal catheter using the same approach. No clinical alterations were recorded during the procedure or the following days. CONCLUSIONS AND CLINICAL RELEVANCE: US-guided spinal catheter placement appeared a feasible technique in piglets younger than 14 days but it is not useful in older piglets. PMID- 29174211 TI - Retrospective study of intra-anesthetic predictors of prolonged hospitalization, increased cost of care and mortality for canine patients at a veterinary teaching hospital. AB - OBJECTIVE: To determine the impact of intraoperative anesthetic variables on the length of hospitalization, cost of care and mortality in dogs. STUDY DESIGN: Retrospective, observational study. ANIMALS: A total of 235 dogs undergoing general anesthesia. METHODS: Medical records of dogs undergoing general anesthesia between 2007 and 2014 at the University of Georgia Veterinary Teaching Hospital were reviewed. Data collected included demographic data, American Society of Anesthesiologists (ASA) physical status, type and duration of anesthesia, hemodynamic variables, temperature, ventilation, fluid therapy and adjunctive drugs administered. Outcome variables were length of hospitalization in the intensive care unit (ICU), hospital charges and survival to discharge. RESULTS: The only factor significantly associated with duration of ICU care was higher ASA status (p<0.0001). Factors associated with increased cost of hospitalization were ICU duration (p<0.0001), anesthesia duration (p<0.0001), hemorrhage amount (p<0.0001), colloid use (p=0.0081), increased age (p=0.0253), increased weight (p = 0.0293) and presence of hypertension (p=0.0179). Overall mortality rate was 5.1%. The only factors negatively associated with survival were the administration of colloids (p<0.0008) and ASA status (p=0.0314). CONCLUSIONS AND CLINICAL RELEVANCE: Several intrinsic patient factors and intraoperative hemodynamic variables were significantly associated with postoperative morbidity and mortality in dogs. These factors might have prognostic value in conjunction with preoperative risk assessment, and patient outcome may be improved by stricter intraoperative control of these variables. PMID- 29174212 TI - Women's Behaviors Toward Mammogram and Pap Test: Opportunities to Increase Cervical Cancer Screening Participation Rates among Older Women. AB - OBJECTIVES: Screening rates for cervical cancer remain moderate among women over 50 years of age. Because cervical and breast screening interventions can be linked, evaluating screening factors relating to both is important. This study evaluates factors associated with breast and cervical screening participation in women aged 52 to 69. METHODS: A cross-sectional study was used to describe characteristics associated with screening behaviors of 1,173,456 eligible women in Ontario, Canada. Overdue for screening was defined as more than 2.5 years from last mammogram or more than 3.5 years from last Pap test. Factors that might influence uptake of mammogram or Pap test were included as covariates in a multivariable multinomial logistic regression model. RESULTS: Overall, 52.4% of eligible women were up-to-date for both, 21.3% were overdue for both, 14.4% were overdue for Pap test but were up-to-date with mammogram, and 11.9% were overdue for mammogram but were up-to-date with Pap test. There was an opposite effect of age on likelihood of being overdue for Pap test only versus mammogram only. Women aged 67 to 69 compared with those 52 to 54 were more likely to be overdue for Pap test only (adjusted odds ratio, 2.3; 95% confidence interval, 2.3-2.4) and less likely to be overdue for mammogram only (adjusted odds ratio, 0.5; 95% confidence interval, 0.5-0.6). A greater proportion of women rostered to a female physician versus a male physician were up-to-date for both (63.7% vs. 51.5%). CONCLUSIONS: Comparing screening patterns may provide physician- and patient-directed strategies to increase cervical screening participation by recruiting women who are overdue for Pap test but undergoing breast cancer screening. PMID- 29174213 TI - Treatment with levothyroxin in subclinical hypothyroidism is associated with increased mortality in the elderly. AB - INTRODUCTION: It is uncertain whether subclinical hypothyroidism should be treated with levothyroxine, particularly in the elderly. This study evaluated the association between levothyroxine treatment and mortality in individuals 65years or older with subclinical hypothyroidism and TSH values <10mIU/L. METHODS: A case control study in which patients 65years or older with TSH levels of 4.2-10mIU/L who died in the years 2012-2016 ('cases') were compared with matched individuals who did not die during this period ('controls'). Matching was based on gender, age, Charlson comorbidity index, date of TSH testing, duration of follow-up and TSH quartile. All cases of known thyroid disease or cases in which anti-thyroid medications or glucocorticoids were dispensed in the year preceding the TSH evaluation were excluded. Use of levothyroxine was compared between groups. RESULTS: During the follow-up period, 419 individuals died and these were matched with 1558 individuals who did not. Factors found to be associated with mortality were age, senile dementia, congestive heart failure, chronic renal failure and a history of cerebrovascular disease. On multivariate analysis, treatment with levothyroxine was associated with significantly increased mortality (HR=1.19 CI 1.03-1.38). Femoral fractures and atrial fibrillation following initiation of levothyroxine therapy were not more prevalent in individuals who died during the follow-up period. CONCLUSIONS: Treatment with levothyroxine is associated with significantly increased mortality in individuals 65years or older with subclinical hypothyroidism and TSH<10.

PMID- 29174215 TI - Choosing Dipeptidyl Peptidase-4 Inhibitors, Sodium-glucose Cotransporter-2 Inhibitors, or Both, as Add-ons to Metformin: Patient Baseline Characteristics Are Crucial. AB - PURPOSE: Type 2 diabetes remains a poorly managed disease, with only about half of individuals with type 2 diabetes meeting guideline-recommended glycosylated hemoglobin (HbA1C) targets. A major proportion of those who have not met HbA1C goals have an HbA1C <8.0% to 8.5%. In practice, it is quite common to have to decide between dipeptidyl peptidase-4 inhibitors (DPP-4i) and sodium-glucose cotransporter-2 inhibitors (SGLT2i) as add-ons to metformin to help these individuals meet their HbA1C goals. This commentary reviews and provides guidance on how baseline factors can assist in the decision between the 2 classes or using both as add-ons to metformin. METHODS: The important clinical studies comparing the glycemic efficacy of DPP-4i versus SGLT2i or their combination as add-ons to metformin with a focus on the influence of baseline HbA1C on glycemic efficacy will be discussed and interpreted. The impact of estimated glomerular filtration rate and age on the glycemic efficacy of DPP-4i and SGLT2i will also be put into perspective. FINDINGS: At HbA1C <8.0% to 8.5%, HbA1C lowering is slightly greater with DPP-4i than with SGLT2i as an add-on to metformin; SGLT2i are associated with larger HbA1C improvements than DPP-4i at higher HbA1C levels. In cases of HbA1C >=8.0%, dual DPP-4i-SGLT2i add-on therapy to metformin should be considered to help more patients achieve glycemic targets. The glycemic efficacy of SGLT2i, but not DPP-4i, declines with progressive renal insufficiency. In older adults, DPP-4i maintain their tolerability and efficacy, while SGLT2i may become less efficacious due to reduced renal function, and may be associated with higher rates of volume-related adverse effects. IMPLICATIONS: Although both DPP-4i and SGLT2i are effective add-on antihyperglycemic therapies to metformin monotherapy, baseline characteristics, such as HbA1C, renal function, and age, should be considered when choosing between the 2 classes to allow for optimal and timely diabetes management. PMID- 29174216 TI - Pharmacokinetics of a New Amphetamine Extended-release Oral Liquid Suspension Under Fasted and Fed Conditions in Healthy Adults: A Randomized, Open-label, Single-dose, 3-treatment Study. AB - PURPOSE: A new amphetamine extended-release liquid formulation (AMP XR-OS), intended for the treatment of attention-deficit/hyperactivity disorder, has been developed. This study was performed to determine if administration with food affected the rate of absorption or bioavailability of AMP XR-OS. The formulation was also compared with an equivalent dose of an extended-release mixed amphetamine salts reference product (30 mg) under fed conditions. METHODS: Thirty adult volunteers participated in this single-dose, open-label, randomized, 3 period, 3-treatment crossover study. Each participant received a single 15-mL dose of AMP XR-OS (equivalent to 30 mg of the reference drug) under fasted conditions, a single 15-mL dose of AMP XR-OS under fed conditions, and a single dose of the reference drug under fed conditions. A 7-day washout separated the 3 treatment periods. Blood samples were collected at predetermined time points and analyzed for d- and l-amphetamine. Pharmacokinetic parameters reported are AUC0 5, AUC0-last, AUC5-last, and AUC0-infinity; Cmax; elimination t1/2; and Tmax. The geometric mean ratios and 90% CIs of Cmax, AUC0-last, and AUC0-infinitywere determined for the comparison of AMP XR-OS fed and fasted, and Cmax, AUC0-5, AUC5 last, and AUC0-infinity were calculated for AMP XR-OS compared with the reference drug under fed conditions. Safety was also assessed. FINDINGS: Twenty-nine subjects completed the study. Subjects were mostly male, white, and of Hispanic/Latino ethnicity with a mean age of 35.83 years and a mean BMI of 25.36kg/m2. The 90% CIs of Cmax, AUC0-last, and AUC0-infinity for AMP XR-OS fasted versus fed were within the accepted 80% to 125% range, indicating lack of a food effect. In the comparison of AMP XR-OS fed versus the reference product, Cmax, AUC5-last, and AUC0-infinity were within the range to establish bioequivalence; however, AUC0-5 was significantly higher for AMP XR-OS compared with that of the reference drug. This difference between products was likely due to the known delay of Tmax and decreased exposure when the extended-release mixed amphetamine salts reference product is administered with food. A total of 36 mild or moderate adverse events were reported; 1 subject withdrew due to an adverse event, and no deaths occurred. These adverse events were consistent with the known pharmacodynamic effects of amphetamine. IMPLICATIONS: The absence of a food effect may allow for AMP XR-OS to be administered with or without a meal.

PMID- 29174218 TI - Individual differences in fear relapse. AB - Vulnerability to anxiety disorders might be due to enhanced acquisition of aversive associations, impaired inhibition of those associations (extinction), and/or vulnerability to the return of fear (relapse). Animal research investigating the processes underpinning fear learning, extinction, and relapse will be critical to further advancing our understanding of anxiety disorders and their treatment. Here we examined whether individual differences in the rate of extinction might be related to vulnerability to relapse. Relapse of fear was examined by testing animals for conditioned freezing using renewal, reinstatement, and spontaneous recovery procedures. Across all three experiments we found that when tested under "milder" relapse conditions (in a novel context, after a mild reinstatement procedure, or 8 days after extinction training) Slow Extinguishers exhibited relapse of fear whereas Fast Extinguishers did not. However, when tested under "stronger" relapse conditions (in the training context, after a strong reinstatement procedure, or 29 days after extinction training) both Fast and Slow Extinguishers exhibited comparable relapse of fear. These results show that Slow Extinguishers are more vulnerable to relapse than Fast Extinguishers. These findings have clinical implications for identifying those most at risk of relapse following treatment and highlight the importance of developing further strategies to reduce relapse. PMID- 29174219 TI - Familial diabetes of adulthood: A bin of ignorance that needs to be addressed. AB - AIMS: The aim of this article was to share with a wide readership some data and related reasoning about a multigenerational form of diabetes mellitus of adulthood. DATA SYNTHESIS: We have recently described a familial form of diabetes mellitus, which in the routine clinical setting of adult individuals is simplistically diagnosed as type 2 diabetes. Such misdiagnosis involves as much as 3% of adult unrelated diabetic patients with no evidence of autoimmune disease. More recent data, obtained by means of a next-generation sequencing, indicate that approximately 25% of such patients carry mutations in the genes involved in monogenic diabetes, thus leaving unraveled the molecular causes of the remaining 75% individuals. CONCLUSIONS: Our proposal is to define the latter patients as being affected by familial diabetes of adulthood (FDA), a clear admission of ignorance and a limbo where adult patients with multigenerational diabetes with no genetic definition of their hyperglycemia have to wait for better times. PMID- 29174220 TI - Outcomes of children supported with devices labeled as "temporary" or short term: A report from the Pediatric Interagency Registry for Mechanical Circulatory Support. AB - BACKGROUND: Historically, the "temporary" or short-term ventricular assist device (VAD) was used only as a quick bridge to recovery for children with an acute process. In the current era, the devices that were originally used for temporary support are now being used to support children for longer durations and for a variety of indications. In this study we aimed to describe the overall use, patients' characteristics and outcomes of "temporary" VAD use in children. METHODS: The Pediatric Interagency Registry for Mechanical Circulatory Support (PediMACS) is a National Institutes of Health-supported national registry for United States Food and Drug Administration-approved VADs in patients <19 years of age at the time of VAD implantation (either durable or temporary VAD). Patients undergoing placement of a device classified as a temporary VAD between September 19, 2012 and June 30, 2016 were included. RESULTS: Temporary VADs were implanted in 63 patients at 20 centers, accounting for 19% of all pediatric VAD patients entered into PediMACS. The median age at implantation was 3.7 (range <1 day to 18) years. The underlying diseases were: congenital heart disease in 26 (41%), 20 of whom were classified as single ventricle; cardiomyopathy in 25 (40%); and myocarditis/rejection in 12 (19%). Patients were predominately Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) Profile 1 (51%), and 10 patients (16%) had previously been supported with extracorporeal membrane oxygenation. Median duration of support was 15 (range <1 day to 227) days, with 41 patients (65%) being on support for >=10 days. The most frequent adverse events were bleeding (29% of patients) and neurologic dysfunction (24% of patients). Overall, 71% (45) achieved a positive outcome (defined as bridge to recovery [30%], transplantation [17%], alive on device [2%] or transition to durable VAD [22%]). Eighty-eight percent (n = 22) of the cardiomyopathy patients and 60% (n = 12) of the single-ventricle patients achieved a favorable outcome. CONCLUSION: Devices historically classified as "temporary" pumps are being used not only as a short-term mechanical circulatory support strategy but also as a longer term support strategy. In this multi-institutional, high-acuity, complex patient cohort, the use of "temporary" VADs resulted in a positive outcome (bridge to transplant, recovery durable device or alive) in 71% of patients. PMID- 29174221 TI - Lung Toxicity in Non-Small-Cell Lung Cancer Patients Exposed to ALK Inhibitors: Report of a Peculiar Case and Systematic Review of the Literature. AB - Lung toxicity is a potential fatal effect involving non-small-cell lung cancer (NSCLC) patients exposed to tyrosine kinase inhibitors (TKIs). Moving from our experience regarding a patient who developed lung toxicity while receiving 2 different anaplastic lymphoma kinase (ALK)-TKIs, we performed a systematic review to assess the epidemiologic magnitude and the clinical significance of such toxicity in NSCLC patients treated with ALK-TKIs. Studies were identified using MEDLINE and additional sources (European Society for Medical Oncology, American Society of Clinical Oncology, and World Conference on Lung Cancer abstracts) in agreement with Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Cochrane guidelines. Lung toxicity was reported in 105 of 4943 NSCLC patients (2.1%). Crizotinib was responsible for pulmonary adverse events (AEs) in 1.8% of exposed patients (49 of 2706). With the limit of a lower number of treated patients (n = 359), brigatinib resulted as the most frequently involved in lung toxicity (7%; n = 25). Pulmonary AEs during therapy with ceritinib, alectinib, and lorlatinib occurred in 1.1%, 2.6%, and 1.8% of the patients, respectively. Sixty-five percent of cases accounted for Grade 3 or 4 events, with a mortality rate of 9%. Radiological patterns of pneumonia were reported in 25 patients, whereas imaging evocative of interstitial lung disease in 37. Overall, 26 of 105 patients (25%) permanently discontinued treatment because of lung toxicity. Lung toxicity is a rare albeit potentially severe side effect in NSCLC patients receiving ALK-TKIs, apparently more frequent with brigatinib. Its early recognition and treatment are crucial for the best outcome of this subgroup of patients, whose overall prognosis is being improved by the availability of several targeted agents. PMID- 29174222 TI - Inter- and intrarater reliability of two proprioception tests using clinical applicable measurement tools in subjects with and without knee osteoarthritis. AB - BACKGROUND: The therapeutic value of proprioceptive-based exercises in knee osteoarthritis (KOA) management warrants investigation of proprioceptive testing methods easily accessible in clinical practice. OBJECTIVE: To estimate inter- and intrarater reliability of the knee joint position sense (KJPS) test and knee force sense (KFS) test in subjects with and without KOA. DESIGN: Cross-sectional test-retest design. METHOD: Two blinded raters performed independently repeated measures of the KJPS and KFS test, using an analogue inclinometer and handheld dynamometer, respectively, in eight KOA patients (12 symptomatic knees) and 26 healthy controls (52 asymptomatic knees). Intraclass correlation coefficients (ICCs; model 2,1), standard error of measurement (SEM) and minimal detectable change with 95% confidence bounds (MDC95) were calculated. RESULTS: For KJPS, results showed good to excellent test-retest agreement (ICCs 0.70-0.95 in KOA patients; ICCs 0.65-0.85 in healthy controls). A 2 degrees measurement error (SEM 1 degrees ) was reported when measuring KJPS in multiple test positions and calculating mean repositioning error. Testing KOA patients pre and post therapy a repositioning error larger than 4 degrees (MDC95) is needed to consider true change. Measuring KFS using handheld dynamometry showed poor to fair interrater and poor to excellent intrarater reliability in subjects with and without KOA. CONCLUSIONS: Measuring KJPS in multiple test positions using an analogue inclinometer and calculating mean repositioning error is reliable and can be used in clinical practice. We do not recommend the use of the KFS test to clinicians. Further research is required to establish diagnostic accuracy and validity of our KJPS test in larger knee pain populations.

PMID- 29174225 TI - Diagnostic Accuracy of Digital Breast Tomosynthesis in the Evaluation of Palpable Breast Abnormalities. AB - RATIONALE AND OBJECTIVES: The role of digital breast tomosynthesis (DBT) in evaluating palpable abnormalities has not been evaluated and its accuracy compared to 2D mammography is unknown. The purpose of this study was to evaluate combined 2D mammography, DBT, and ultrasound (US) at palpable sites. MATERIALS AND METHODS: Two breast imagers reviewed blinded consecutive cases with combined 2D mammograms and DBT examinations performed for palpable complaints. By consensus, 2D and DBT findings were recorded and compared to US. Patient characteristics, demographics, subsequent workup, and outcome were recorded. RESULTS: A total of 229 sites in 188 patients were included, with 50 biopsies performed identifying 18 cancers. All 18 cancers were identified on 2D and US, whereas 17 cancers were identified on DBT. Cancer detection sensitivities for 2D, DBT, and US were 100.0%, 94.4%, and 100.0%. The negative predictive value, when combined with US, was 100% for both. The sensitivity and the specificity for both benign and malignant findings with 2D and DBT were 70.5% versus 75.4% (P = 0.07) and 95.3% versus 99.1% (P = 0.125). Palpable findings not identified by 2D and DBT were smaller than those identified (11.5 +/- 8.3 mm vs 23.9 +/- 12.8 mm, P < 0.001). Patients with dense breasts were more likely to have mammographically occult findings than patients with nondense breasts (27.4% vs 8.3%). CONCLUSIONS: DBT did not improve cancer detection over 2D or US. Both mammographic modalities failed to identify sonographically confirmed findings primarily in dense breasts. The diagnostic use of DBT at palpable sites provided limited benefit over combined 2D and US. When utilizing DBT, US should be performed to adequately characterize palpable sites. PMID- 29174226 TI - Optical Coherence Tomography: A Novel Imaging Method for Post-lumpectomy Breast Margin Assessment-A Multi-reader Study. AB - RATIONALE AND OBJECTIVES: This study aimed to assess whether different breast cancer subspecialty physicians can be trained to distinguish non-suspicious from suspicious areas of post-lumpectomy specimen margin in patients with breast cancer using optical coherence tomography (OCT) images (a near-infrared based imaging technique) with final histology as the reference standard. MATERIALS AND METHODS: This institutional review board-exempt, Health Insurance Portability and Accountability Act-compliant study was performed on 63 surgically excised breast specimens from 35 female patients, creating a 90-case atlas containing both non suspicious and suspicious areas for cancer. OCT images of the specimens were performed, providing 6.5-15 um resolution with tissue visualization 1-2 mm subsurface. From the 90-case atlas, 40 cases were chosen for training and 40 were randomly selected for reader assessment. Three breast imaging radiologists, two pathologists, two breast surgeons, and one non-clinical reader were trained and assessed for ability to distinguish non-suspicious from suspicious findings blinded to clinical data and corresponding histology slides. Duration of training and assessment, sensitivity, specificity, positive predictive value, negative predictive value, and the area under the curve for each reader were calculated as well as averages by subspecialty. RESULTS: The average training time was 3.4 hours (standard deviation, 1.2). The average assessment time was 1.9 hours (standard deviation, 0.7). The overall average reader sensitivity, specificity, and accuracy for detecting suspicious findings with histologic confirmation of cancer at the surgical margin for all eight readers were 80%, 87%, and 87%, respectively. Radiologists demonstrated the highest average among the disciplines, 85%, 93%, and 94%, followed by pathologists, 79%, 90%, and 84%, and surgeons, 76%, 84%, and 82% respectively. CONCLUSIONS: With relatively short training (3.4 hours), readers from different medical specialties were able to distinguish suspicious from non-suspicious OCT imaging findings in ex vivo breast tissue as confirmed by histology. These results support the potential of OCT as a real-time intraoperative tool for post-lumpectomy specimen margin assessment. PMID- 29174227 TI - Angiogenic and antiangiogenic factors in preeclampsia. AB - BACKGROUND: Pre-eclampsia is a multifactorial hypertensive disorder that is triggered by placental insufficiency and that accounts for up to 15% of maternal deaths. In normal pregnancies, this process depends on the balance between the expression of angiogenic factors and antiangiogenic factors, which are responsible for remodeling the spiral arteries, as well as for neoangiogenesis and fetal development. PURPOSE: The aim of this review is to discuss the main scientific findings regarding the role of angiogenic and antiangiogenic factors in the etiopathogenesis of preeclampsia. METHODS: An extensive research was conducted in the Pubmed database in search of scientific manuscripts discussing potential associations between angiogenic and antiangiogenic factors and preeclampsia. Ninety-one papers were included in this review. RESULTS: There is an increased expression of soluble fms-like tyrosine kinase receptor and soluble endoglin in pre-eclampsia, as well as reduced placental expression of vascular endothelial growth factor and placental growth factor. Systemic hypertension, proteinuria and kidney injury - such as enlargement and glomerular fibrin deposit, capillary occlusion due to edema, and hypertrophy of endocapillary cells - are some of these changes. The complex etiopathogenesis of preeclampsia instigates research of different biomarkers that allow for the early diagnosis of this entity, such as vascular endothelial growth factor, placental growth factor, soluble fms-like tyrosine kinase receptor, soluble endoglin, placental glycoprotein pregnancy-associated plasma protein-A and protein 13. CONCLUSION: Even though it is possible to establish an efficient and effective diagnostic tool, three key principles must be observed in the management of preeclampsia: prevention, early screening and treatment. PMID- 29174228 TI - Rare Concurrent Retroclival and Pan-Spinal Subdural Empyema: Review of Literature with an Uncommon Illustrative Case. AB - BACKGROUND: Subdural empyema can present as a spinal subdural empyema (SSE) or a cranial subdural empyema (CSE). Although they differ somewhat in epidemiology, etiology, pathophysiology, and symptomatology and occur separately, they rarely manifest together. The aim of this article is to review the literature concerning the clinical presentation, clinical course, and treatment options for managing concurrently occurring SSE and CSE. METHODS: The literature in the Medline database was reviewed with key words including but not limited to subdural empyema, retroclival empyema, and Streptococcus mitis. No similar reports were found in the database involving infection with this type of microorganism in this anatomical region. RESULTS: Only 3 cases with concurrent CSE and SSE were found in the literature caused by various etiologic agents. Two of the patients recovered with no neurologic deficit, whereas one fatality was reported. One new illustrative case caused by Streptococcus mitis is also presented. CONCLUSIONS: CSE and SSE are neurosurgical emergencies, often requiring prompt surgical evacuation. Although very rare, Streptococcus mitis can cause spinal subdural empyema or retroclival abscesses. Natural history of this disease is grave without treatment. Delays in diagnosis and treatment are directly related to mortality and severe morbidity in patients with intracranial and spinal subdural empyema. Prompt recognition and treatment are essential to preclude severe neurologic disabilities or in rare cases a fatal outcome. A treatment paradigm for cranio-spinal empyema is proposed. PMID- 29174229 TI - Repair of Cerebrospinal Fluid Leakage Using a Transfrontal, Radial Adipofascial Flap: An Individual Approach Supported by Three-Dimensional Printing for Surgical Planning. AB - BACKGROUND: Leakage of cerebrospinal fluid (CSF) because of large prolactinomas represents a complex issue. Because of limited anatomic space, multiple leakage sites, and scarce locally available tissue for repair, surgical possibilities are limited. We report an initial case of using a radial fasciocutaneous flap applied subfrontally to cover a large skull base defect, supported by preoperative three dimensional (3D) printing for surgical planning. CASE DESCRIPTION: A 29-year-old woman developed severe nuchal pain that was caused by destruction of large parts of her skull base by a prolactinoma. After occipitocervical fusion, medical treatment showed good tumor response but led to CSF leakage after 12 months. An endoscopic approach and ventriculoperitoneal shunt implantation failed to stop the leakage. A 3D model of the skull improved the understanding of the expanded osseous destruction and multiple CSF leakage sites and supported surgical planning. For an extensive coverage of the former clivus and sella region, an intracranially applied radial flap was planned. Dopamine-agonist medication was increased before the operation. Intraoperatively, the flap was brought into position subchiasmatically and wound around the pituitary stalk. CSF leakage was not observed on follow-up (10 weeks). Long-term follow-up will determine the effectiveness of this method. PMID- 29174230 TI - Utility of the Lateral Base Dural Tacking Method in Cord Tumor Surgery Performed Using Unilateral Hemilaminectomy: A Comparison of Dural Window Widths. AB - OBJECTIVE: Unilateral hemilaminectomy, which is used to remove spinal cord tumors, is simpler than laminoplastic laminotomy and affords certain biomechanical advantages. However, both incomplete tumor removal and inadvertent infliction of spinal cord damage attributable to the narrow surgical corridor remain of concern. When a spinal cord tumor is to be removed, it is important to ensure that the dural window along the surgical corridor is of adequate width. This study aimed to determine that the utility of lateral base dural tacking (LBT) method when cord tumor surgery is performed using a unilateral hemilaminectomy-a comparison of dural window widths with a traditional dural tack up and a suspending-out (DSO) method with the aid of digital image-analysis software. METHODS: Twenty-one consecutive patients who had intradural extramedullary spinal cord tumors removed using a unilateral hemilaminectomy were included in the study and analyzed retrospectively. We acquired DSO and LBT dural window images using surgical microscopes under identical conditions in consecutive order and then removed the tumors using the LBT method. We used digital image-analysis software to analyze the images quantitatively. The pixel numbers of LBT and DSO window were compared using a paired t test. RESULTS: Twenty-one tumorous lesions were successfully removed without any major problems using a unilateral hemilaminectomy through LBT windows. The mean pixel numbers of the LBT and DSO windows were 126,787 +/- 41,938 and 85,940 +/- 21,638. The LBT windows were 46% larger than the DSO windows (P < 0.001). CONCLUSIONS: We objectively proved that the utility of the LBT method for widening the surgical corridor created during hemilaminectomy.

PMID- 29174232 TI - Endovascular Mechanical Thrombectomy in Large-Vessel Occlusion Ischemic Stroke Presenting with Low National Institutes of Health Stroke Scale: Systematic Review and Meta-Analysis. AB - INTRODUCTION: Mechanical thrombectomy has become the standard of care for management of most large vessel occlusion (LVO) strokes. When patients with LVO present with minor stroke symptomatology, no consensus on the role of mechanical thrombectomy exists. METHODS: A systematic review and meta-analysis were performed to identify studies that focused on mechanical thrombectomy, either as a standalone treatment or with intravenous tissue plasminogen activator (IV tPA), in patients with mild strokes with LVO, defined as a baseline National Institutes of Health Stroke Scale score <=5 at presentation. Data on methodology, quality criteria, and outcome measures were extracted, and outcomes were compared using odds ratio as a summary statistic. RESULTS: Five studies met the selection criteria and were included. When compared with medical therapy without IV tPA, mechanical thrombectomy and medical therapy with IV tPA were associated with improved 90-day modified Rankin Scale (mRS) score. Among medical patients who were not eligible for IV tPA, those who underwent mechanical thrombectomy were more likely to experience good 90-day mRS than those who were not. There was no significant difference in functional outcome between mechanical thrombectomy and medical therapy with IV tPA, and no treatment subgroup was associated with intracranial hemorrhage or death. CONCLUSIONS: In patients with mild strokes due to LVO, mechanical thrombectomy and medical therapy with IV tPA led to better 90 day functional outcome. Mechanical thrombectomy plays an important role in the management of these patients, particularly in those not eligible for IV tPA. PMID- 29174233 TI - Effectiveness of Gamma Knife Radiosurgery in Improving Psychophysical Performance and Patient's Quality of Life in Idiopathic Trigeminal Neuralgia. AB - OBJECTIVE: To assess effectiveness of Gamma Knife Radiosurgery (GKRS) in improving quality of life (QoL) in patients with idiopathic trigeminal neuralgia (TN). METHODS: Between January 2001 and October 2013, 166 patients with medically resistant TN were treated at our institution with GKRS. Patients were divided into 2 groups: patients with typical TN (TTN) and patients with atypical TN (ATN). All patients underwent clinical evaluation using Marseille and Barrow Neurological Institute pain and numbness scales; in addition, they completed the Short-Form 36 Health Survey, Activities of Daily Living, and Excellent Good Fair Poor questionnaires and underwent psychological and neurologic examination. RESULTS: Mean follow-up time was 64.7 months. All Short-Form 36 domains were significantly improved in both groups after treatment, with an evident trend to reach the median values of healthy Italian population. Mean postoperative Activities of Daily Living score in the TTN group and ATN group were 5.8 and 5.4, respectively, and Karnofsky Performance Status increased to 94.2 and 86.4, respectively. Pain recurrence negatively affected patients' QoL and psychofunctional performance without reaching statistical significance. At the last follow-up, 73% of patients were clustered in the pain-relief group. CONCLUSIONS: GKRS significantly improves QoL and functional and psychosocial performance of patients with idiopathic trigeminal neuralgia. A trend was observed toward a more favorable outcome in patients with TTN, compared with patients with ATN, without reaching a statistically significant distinction. PMID- 29174234 TI - In Situ Side-to-Side Anastomosis: Surgical Technique and Complication Avoidance. AB - In situ side-to-side (STS) anastomosis is a unique technique used for intracranial artery-intracranial artery revascularization. Over a 7-year period, 7 STS anastomoses were performed for anterior cerebral artery aneurysms in 6 patients and a posteroinferior cerebellar artery aneurysm in 1 patient. We provide a step-by-step guide for suturing techniques from arteriotomy to vessel wall sutures based on clinical experiences, with detailed illustrations. Technical considerations in each stage are also discussed. The current technique provides a viable option for treatment of complex aneurysms. PMID- 29174235 TI - Hybrid Recanalization for Symptomatic Long-Segmental Occlusion Post Vertebral Artery Stenting. AB - BACKGROUND: A hybrid operation combining endovascular and open surgery procedures is supposed to achieve recanalization for post-stenting long-segmental occlusion of the vertebral artery (VA) ostium simultaneously. CASE DESCRIPTION: One patient with post-stenting long-segmental occlusion in VA ostium was reported. His symptoms could not be relieved by medical therapy. Recanalization combining endovascular and open surgery procedures simultaneously was performed. The hybrid recanalization was successful, and the patient demonstrated no symptoms attacked during the follow-up. CONCLUSIONS: Hybrid operation is a potential and feasible method to recanalize the long-segmental occlusion in the VA ostium post-stenting treatment. PMID- 29174236 TI - Paradoxical Distraction with Upright Position After Halo Fixation in 2 Patients with Atlanto-Occipital Dislocation. AB - BACKGROUND: Atlanto-occipital dislocation (AOD) is the most uncommon form of traumatic cervical spine injury. The majority of patients die before reaching higher-level care, and only a small percentage of patients with AOD survive the initial injury after receiving tertiary care. As such, there is a paucity of evidence-based management guidelines for treating this condition. Halo vest fixation has been a proposed method for interim stability while these patients undergo medical optimization for surgical intervention. There have been several reports of worsening AOD after halo placement. Reverse Trendelenburg position after halo fixation has been previously described to aid in the reduction of AOD, as well as concomitant atlantoaxial dislocation by gravitational downward force. CASE DESCRIPTION: In this series we present 2 cases of obese patients (body mass index >30) with AOD treated by halo fixation that had increased distraction after head of bed elevation. CONCLUSION: Our theorized mechanism for this phenomenon is due to the downward pull of subaxial forces secondary to a large body habitus. PMID- 29174237 TI - Midline Ligamentum Flavum Cyst of Lumbar Spine. AB - BACKGROUND: Ligamentum flavum cysts are thought to develop due to facet joint hypermobility; however, the etiology of these lesions is not completely elucidated. These cysts may lead to compressive pathologies of the spine requiring surgical intervention. CASE REPORT: We report the case of a 63-year-old male with chronic back pain and progressive neurogenic claudication for 6 months. He was found to have a ligamentum flavum cyst situated along the dorsal midline of the lumbar spinal canal contributing to spinal stenosis. The patient underwent a decompressive L4 laminectomy and en bloc excision of the ligamentum flavum cyst with complete resolution of his symptoms postoperatively. CONCLUSIONS: We suggest that chronic mechanical stress leads to degeneration of the ligamentum flavum and contributes directly to cyst formation. PMID- 29174238 TI - Association of Hospital Teaching Status with Neurosurgical Outcomes: An Instrumental Variable Analysis. AB - BACKGROUND: The interpretation of the results of prior studies on the association of hospital teaching status with surgical outcomes is limited by selection bias. We investigated whether undergoing surgical operations in teaching hospitals is associated with improved outcomes. METHODS: We performed a cohort study of all patients undergoing spine and cranial operations who were registered in the New York Statewide Planning and Research Cooperative System database from 2009 to 2013. We examined the association of teaching status (defined as academic affiliation for the primary analysis) with inpatient case fatality, discharge to a facility, and length of stay (LOS). An instrumental variable analysis was used to control for unmeasured confounding and to simulate the effect of a randomized trial. RESULTS: During the study period, 186,483 patients underwent surgical operations that met the inclusion criteria. Instrumental variable analysis demonstrated that hospitalization in teaching hospitals was associated with higher rates of case fatality (adjusted difference, 25%; 95% confidence interval [CI], 4%-46%), discharge to a facility (adjusted difference, 5.7%; 95% CI, 4.5% 7.0%), and longer LOS (adjusted difference, 31.4%; 95% CI, 16.0%-46.1%) in comparison with nonteaching hospitals. The same associations were present in propensity score adjusted mixed effects models. These persisted in prespecified subgroups stratified on particular operations and for different definitions of teaching hospitals. CONCLUSIONS: Using a comprehensive all-payer cohort of surgical patients in New York State, we identified an association of treatment in teaching hospitals with increased case fatality, rate of discharge to rehabilitation, and longer LOS. Further research into the factors contributing to superior outcomes in nonteaching institutions is warranted. PMID- 29174239 TI - Efficiency and Safety of Autologous Fat Grafts in Reconstructing Skull Base Defects After Resection of Skull Base Meningiomas. AB - BACKGROUND: Reconstruction of the skull base after resection of skull base meningiomas is of paramount importance. Here we describe a safe and effective method of skull base reconstruction using autologous free fat grafts. METHODS: In this retrospective analysis of patients operated for skull base meningioma from 2007 to 2014. We analyzed the surgical technique, efficiency and safety as well as the graft-related complications. RESULTS: Autologous free fat grafts were used in 55 patients, including 39 patients with posterior fossa meningiomas related to the petrous bone and 16 patients with anterior fossa meningiomas related to the paranasal sinuses. Three patients experienced postoperative cerebrospinal fluid (CSF) leak and were managed with temporary continuous lumbar drainage. One patient developed pneumocephalus and required revision. The occurrence of CSF leak was related to aggressive resection with resulting large skull base defects, especially in anterior skull base meningiomas. There were no donor site-related complications. CONCLUSIONS: The use of autologous free fat grafts is an effective and safe technique for reconstructing skull base defects after microsurgical resection of skull base meningiomas. PMID- 29174240 TI - Predicting Resident Performance from Preresidency Factors: A Systematic Review and Applicability to Neurosurgical Training. AB - BACKGROUND: Neurosurgical educators strive to identify the best applicants, yet formal study of resident selection has proved difficult. We conducted a systematic review to answer the following question: What objective and subjective preresidency factors predict resident success? METHODS: PubMed, ProQuest, Embase, and the CINAHL databases were queried from 1952 to 2015 for literature reporting the impact of preresidency factors (PRFs) on outcomes of residency success (RS), among neurosurgery and all surgical subspecialties. Due to heterogeneity of specialties and outcomes, a qualitative summary and heat map of significant findings were constructed. RESULTS: From 1489 studies, 21 articles met inclusion criteria, which evaluated 1276 resident applicants across five surgical subspecialties. No neurosurgical studies met the inclusion criteria. Common objective PRFs included standardized testing (76%), medical school performance (48%), and Alpha Omega Alpha (43%). Common subjective PRFs included aggregate rank scores (57%), letters of recommendation (38%), research (33%), interviews (19%), and athletic or musical talent (19%). Outcomes of RS included faculty evaluations, in-training/board exams, chief resident status, and research productivity. Among objective factors, standardized test scores correlated well with in-training/board examinations but poorly correlated with faculty evaluations. Among subjective factors, aggregate rank scores, letters of recommendation, and athletic or musical talent demonstrated moderate correlation with faculty evaluations. CONCLUSION: Standardized testing most strongly correlated with future examination performance but correlated poorly with faculty evaluations. Moderate predictors of faculty evaluations were aggregate rank scores, letters of recommendation, and athletic or musical talent. The ability to predict success of neurosurgical residents using an evidence-based approach is limited, and few factors have correlated with future resident performance. Given the importance of recruitment to the greater field of neurosurgery, these data provide support for a national, prospective effort to improve the study of neurosurgery resident selection. PMID- 29174241 TI - A Novel Skin and Fascia Opening for Subfascial Inserting of Intrathecal Baclofen Pump. AB - OBJECTIVE: The aim of this article is to introduce a new skin and fascia opening for intrathecal baclofen pump implantation in the abdomen, with the purpose of reducing complications related to wound breakdown. METHODS: We introduce a novel way of cutaneous and fascial opening that leads two opposed "L shaped" incisions. RESULTS: This method entails numerous advantages. The first advantage is avoiding the direct alignment of overlapped sutures, which creates a locus minoris resistentiae that can weaken and break under the push of the pump. Another advantage consists of an increased obstruction against deep extension of infective processes from cutaneous origin. The wide opening of the subfascial pocket permits the implantation of any type of pump available, and it reduces complexities in reopening the pouch for pump replacement. It also permits the fastening of all anchoring systems usually present in pumps. Another advantage is the improved possibility of careful muscle cauterization thanks to the wide fascia opening, with reduced risk of postsurgical hematoma. Our results showed a reduction of wound complications with this method. CONCLUSIONS: This method could contribute to reducing the rate of wound complications and patient discomfort. PMID- 29174242 TI - Bioresorbable scaffold -fourth revolution or failed revolution: Is low scaffold strut thickness the wrong target? AB - Bioresorbable scaffold (BRS) technology has currently fallen into disrepute because of inordinately high risk of scaffold thrombosis and post-procedure myocardial infarction. Low tensile and radial strengths of polymeric BRS contributing to improper strut embedment have been identified as major correlates of poor outcomes following BRS implantation. Magnesium has a better tensile/radial strength compared with polymeric BRS but it is still far lower than cobalt-chromium. Newers innovations utilizing alteration in polymer composition and orientation or even newer polymers have focused on attempts to reduce strut thickness but may have little effect on tensile/radial strength of finished product and therefore may not impact the BRS outcome on long run. Currently, newer generation BRS usage may be restricted to suitable low risk younger patients with proper vessel preparation and application of technique. PMID- 29174243 TI - Evaluation and efficacy of long length Pronova XR Bioabsorbable Polymer stent in the treatment of long coronary lesions. AB - AIM: The study aims an observational registry of the long and extra-long length (>33mm) Pronova XR stents in patients with long coronary lesions (>30mm) in a prospective real world study. METHODS AND RESULTS: Current study was conducted at Ruby Hall Clinic Pune, between July 2012 and July 2013 including 30 patients who underwent PTCA using long and extra-long Pronova XR stents. Among the stents used, one stent - 33mm, 2 stents - 38mm, 5 stents - 43mm and 25 stents were of 48mm in length. In particular average stent length for the study was 46.03mm and the average stent diameter was 3.09+/-0.41mm. For this study coronary angioplasty was performed using femoral approach and standard practice. Lesions were predilated using undersized balloons and study stent was deployed at pressure 7 26atm. (12.8+/-3.2atm.) The successful delivery of stent at the intended lesion with visual residual stenosis less than 50% was defined as Procedural success. Follow up studies were conducted for all the patients at 30days, 3 months and 6 months intervals. The predefined QCA parameters were calculated using Sanders Data System QCA plus software (Palo Alto, CA, USA). No procedural complication was observed during the whole study. 100% successful stent placement was achieved in all patients. Six months clinical follow-up was available for all patients. No adverse events (Acute closure, angina, REPCI, MI, death, sub acute stent thrombosis) or hospitalization was reported for any of the patients except one. The Quantative Coronary Core Lab analysis post 6 months showed well-flowing stent with average late lumen loss 0.10mm +/-0.26. CONCLUSION: In patients with long coronary lesions and very long length stent implantation series, Pronova XR showed excellent in 6 months results. This is for the first time reported that use of long length Pronova XR stents has shown so low restenosis rate and absent of mortality in six month period. These results offer a new opportunity to single long length stenting. PMID- 29174244 TI - Left ventricular global longitudinal strain following revascularization in acute ST elevation myocardial infarction - A comparison of primary angioplasty and Streptokinase-based pharmacoinvasive strategy. AB - OBJECTIVE: Tenecteplase-based pharmacoinvasive percutaneous coronary intervention (PCI) has been shown to yield outcomes comparable to primary PCI in the setting of acute ST elevation myocardial infarction (STEMI). This study was designed to compare the efficacy of pharmacoinvasive PCI following successful thrombolysis with Streptokinase versus primary PCI in patients with STEMI. METHODOLOGY: We conducted a prospective single center observational study in 120 patients with STEMI who underwent primary PCI (n=60) and Streptokinase-based pharmacoinvasive PCI (n=60). Patients with Killips class 3 or 4 at presentation, and those with evidence of failed fibrinolysis were excluded. The primary outcome was LV systolic function after angioplasty, as assessed by 2D global longitudinal strain (GLS) using speckle tracking echocardiography (STE), as well as 2D LVEF using Simpson's biplane method. RESULTS: LV systolic function after PCI was significantly lower in the pharmacoinvasive arm as compared to the primary PCI arm, both by 2D STE (GLS: -9% vs -11%; p=0.03) and 2D Simpson's biplane method (LVEF: 40.7% vs 45.1%; p=0.02). TIMI flow in the culprit vessel prior to angioplasty was better in the pharmacoinvasive arm indicating successful thrombolysis, whereas post angioplasty flow was not different. There was no in hospital mortality in either group. There was a trend toward increased incidence of acute kidney injury in the pharmacoinvasive arm. CONCLUSION: LV systolic function is significantly better after primary angioplasty as compared to pharmacoinvasive PCI following successful thrombolysis with Streptokinase.

AB - OBJECTIVES: This purpose of the study was to evaluate TAVR outcomes at low, intermediate and high volume institutions. BACKGROUND: For the care of complex patients, volume-outcome effect is well described. The initial US TAVR experience was limited to a few centers of excellence. The impact of institutional volume on outcomes after TAVR has not been systematically studied. METHODS: Within the Banner Health system, TAVR is performed at 3 institutions-a low volume, an intermediate volume and a high volume institution. 181 consecutive patients undergoing TAVR within these 3 institutions were the study cohort. To adjust for bias and confounders between the 3 groups, risk-adjusted multivariate logistic regression and propensity score analysis was performed. The primary endpoint was a composite of mortality, dialysis-dependent renal failure, cerebrovascular accident, need for new permanent pacemaker and readmission within 30days. RESULTS: The primary endpoint was reached in 38.8% of patients at the high volume institution and 76.2% of patients at the low volume institution (p<0.01). Having a TAVR procedure at a larger volume institution was an independent predictor of having improved outcomes (OR 0.33, 95% CI 0.16-0.68; p=0.003). These improved outcomes after the TAVR procedure noted at the large volume institution were seen in the most complex patients: age >=80years, BMI >30, diabetes, hypertension, prior CAD, CKD and NYHA class III/IV heart failure. CONCLUSIONS: High-risk patients undergoing TAVR at a large volume institution have better 30-day outcomes compared to outcomes at intermediate and low volume centers. PMID- 29174246 TI - Incidence of drug-induced torsades de pointes with intravenous amiodarone. AB - AIM: To define the incidence, presentation, and outcomes of drug-induced Torsades de Pointes (TdP) with intravenous (IV) amiodarone. METHODS: From January 2014 to August 2016 a total of 268 patients received IV amiodarone, 142 for ventricular tachycardia, 104 for atrial flutter/fibrillation, and 22 for incessant atrial tachycardia. A uniform dosing of amiodarone to yield 1gm/day was used in all patients. RESULTS: Four of the 268 patients (M:F 1:3) with mean age of 51.25+9.17years developed pause dependent TdP degenerating to VF, after a mean dose of 690+176.63mg, infused over 12+5.88h. The QTc that was 505+9.02ms at the time of TdP normalized to 433.75+6.13ms 48-72h after stopping amiodarone. There was no immediate or late mortality, and patients are well at 5-10 months of follow-up. None of the patients tested positive for LQTS genes. CONCLUSION: The incidence of drug-induced TdP with IV amiodarone is about 1.5%. Risk factors include female sex, left ventricular dysfunction, electrolyte abnormalities, baseline prolonged QTc, concomitant beta-blocker, and digoxin therapy. Amiodarone induced TdP has favorable prognosis if recognized and treated promptly, and these patients should not receive amiodarone by any route in future. PMID- 29174247 TI - Atrial electrical abnormality in patients with Brugada syndrome assessed by signal-averaged electrocardiography. AB - BACKGROUND: Ventricular fibrillation and atrial fibrillation are well-known arrhythmias in patients with Brugada syndrome. This study evaluated the characteristics of the atrial arrhythmogenic substrate using the signal-averaged electrogram (SAECG) in patients with Brugada syndrome. METHODS: SAECGs were performed during normal sinus rhythm in 23 normal volunteers (control group), 21 patients with paroxysmal atrial fibrillation (PAF; PAF group), and 21 with Brugada syndrome (Brugada group). RESULTS: The filtered P wave duration (fPd) in the control, Brugada, and PAF groups was 113.9+/-12.9ms, 125.3+/-15.0ms, and 137.1+/-16.3ms, respectively. The fPd in the PAF group was significantly longer compared to that in the control and Brugada groups (p<0.05). The fPd in the Brugada group was significantly longer than that in the control group (p<0.05) and significantly shorter than that in the PAF group (p<0.05). CONCLUSION: Patients with Brugada syndrome had abnormal P waves on the SAECG. The abnormal P waves on the SAECG in Brugada syndrome patients may have intermediate characteristics between control and PAF patients. PMID- 29174248 TI - Electrocardiographic characteristics in young male patients with left primary spontaneous pneumothorax estimated by the collins equation. AB - OBJECTIVE: To investigate the 12-lead surface electrocardiographic (ECG) findings in young male patients with left primary spontaneous pneumothorax (PSP) estimated by the Collins equation. METHODS: From 2003 through 2008, 60 young male patients who had left PSP and 61 age-matched unaffected males were included for 12-lead ECG analyses. The PSP size was estimated by the Collins equation. Those with left PSP were divided into two groups: 1) large PSP >=30% (n=37), and 2) small PSP <30% (n=23). The ECG in the unaffected was used as the normal control. Baseline demographic, anthropometric, and electrocardiographic findings including heart rate, P-QRS-T axes, wave intervals, and RS voltages were compared among three groups. RESULTS: As compared to the unaffected, patients with left PSP had faster heart rate, longer QTc interval, greater QRS and T axes. With regard to RS amplitudes, greater R in lead aVR and V1, and deeper S in lead II indicating predominant rightward forces, and smaller R in lead I and V3-V6 indicating inferior leftward forces were present in patients with left PSP. Of these ECG findings, heart rate, S voltage in lead II and R voltage in V1 in the large PSP but not in the small PSP had greater values than that in the unaffected group. CONCLUSION: Among young male patients with left PSP estimated by the Collins method, the ECG showed faster heart beat and predominant rightward forces especially for those with large PSP. PMID- 29174249 TI - Low interatrial septal pacing: A simple method. AB - BACKGROUND: Sinus node disease is associated with widespread structural and electrophysiological changes in the atria in addition to abnormalities at the sinus node. The atrial conduction disorder in patients with atrial pacing results in higher incidence of atrial fibrillation. Studies have shown that low interatrial septal pacing is superior to right atrial appendage pacing in preventing persistent or permanent atrial fibrillation in these patients. However, implantation of active fixation lead in low interatrial septal position is difficult and time consuming with conventional stylet, inhibiting application of this method in routine practice. METHOD: The technique of implanting atrial pacing lead in low interatrial septum with hand-made stylet is presented in this study with emphasis on fluoroscopic landmark and electrocardiographic P wave pattern. RESULTS: The results indicate acute and short-term success of low interatrial septal pacing in 10 patients out of 11 patients without major complications. Pacing parameters during implantation and 3 months post procedure were within normal limits. CONCLUSION: The initial favorable results of this study indicate low interatrial septal pacing with conventional active fixation lead using fluoroscopic landmark and electrocardiographic characteristics is feasible and reproducible with a simple technique. PMID- 29174250 TI - Assessment of right ventriclular systolic function prior to cardiac resynchronization therapy: Does it make any difference? AB - BACKGROUND: Cardiac resynchronization therapy (CRT) is an effective treatment for patients with advanced heart failure (HF). Nearly 30% of candidates are inadequate responders. The benefit of patients with right sided heart failure from CRT is still a matter of debate. We examined the effect of CRT on right ventricular (RV) dimensions and overall systolic function and whether RV function prior to CRT could have an impact on CRT response. METHODS: 94 patients with a mean age of 53.7+/-14.6 years including 19 (20%) females, with advanced HF (EF<35%, LBBB>120ms, or non-LBBB>150ms, with NYHA -III or ambulatory class IV) were enrolled and underwent CRT implantation. Standard two dimensional (2D) echocardiography, tissue Doppler imaging, for assessment of Left ventricular (LV) end-diastolic (LVEDV), and end-systolic volumes (LVESV), ejection fraction, RV maximum basal (RVD basal), maximum mid (RVD mid) transverse, maximum longitudinal (RVD long) diameters, TAPSE, fractional area change (FAC), and tricuspid lateral annular systolic velocity (S'), in addition to RV global longitudinal strain (RVGLS) measured by speckle tracking echocardiography, were done before CRT implantation and at the end of the follow up period (5.9+/-1.2 months). Patients presenting with reductions of LVESV of >15% were termed volumetric responders for further statistical analysis. RESULTS: 63 (67%) cases were volumetric responders. Both groups were matched regarding demographic, clinical, ECG, and echocardiographic criteria apart from the RV significantly smaller transverse diameters and significantly better systolic function parameters in the responders group prior to CRT compared to non-responders (NR) group. At the end of the follow up, only the responders group had further significant reduction in RV basal, mid and longitudinal diameters (33.6+/-7.1 vs 40.7+/-8.6, 21.4+/-4.9 vs 27+/-6.1, 68.3+/-10.8 vs 81.2+/-15, respectively), p<0.01, together with significant improvement in RV systolic performance: FAC (47.7+/-7.3 vs 40.9+/ 6.4), TAPSE (25.2+/-4.6 vs 22.1+/-4.9), S' (15.3+/-2.3 vs 12.8+/-2.3), and GLS (26.1+/-2.1 vs 18.5+/-1.6), P<0.01, compared to baseline readings. S' and GLS were the only independent predictors of CRT response by multivariate analysis. S'>9cm/s, and GLS >12.45% had 100% sensitivity and 70%, 99.7% specificity, respectively for prediction of response to CRT. CONCLUSIONS: CRT induces RV reverse remodeling and improves RV systolic function particularly in cardiac volumetric responders. RV systolic dysfunction before CRT implantation could identify patients that might not benefit from CRT thus helping proper patient selection and optimizing CRT response. PMID- 29174251 TI - Effect of ferric carboxymaltose on hospitalization and mortality outcomes in chronic heart failure: A meta-analysis. AB - INTRODUCTION: Iron administration especially intravenous iron therapy is associated with improvements in exercise capacity and quality of life in patients with chronic heart failure (CHF). Our aim was to assess effect of ferric carboxymaltose (FCM) on hospitalization and mortality outcomes in CHF. MATERIALS AND METHODS: A literature search across PUBMED, Google Scholar and trials database www.clinicaltrials.gov was conducted to search for randomized controlled trials (till August 2016) comparing FCM to placebo in CHF with or without anaemia. Published human studies in English language which reported data on mortality and hospitalization rates were included. Primary outcome was rates of HF hospitalizations and secondary outcomes were hospitalization due to any cardiovascular (CV) cause, death due to worsening HF and any CV death. RESULTS: From 17 studies identified, two were included in final analysis (n=760; 455 in FCM and 305 in placebo arms). We observed significantly lower rates of hospitalization for worsening HF in FCM arm [Risk Ratio (RR) 0.34, 95% confidence interval (CI) 0.19, 0.59, p=0.0001] as well as for any CV hospitalizations [RR 0.49, 95% CI 0.35, 0.70; p<0.0001] (figure). No heterogeneity in studies was seen for these two outcomes (I2=0%, p>0.05). No significant treatment effect with FCM was noted in mortality from worsening HF (RR 0.41, 95% CI 0.02, 7.36; p=0.55) or any CV death (RR 0.80, 95% CI 0.40, 1.57; p=0.51). CONCLUSION: FCM reduces hospitalization rates in CHF but may not reduce mortality outcome. This finding needs further evaluation in a large, prospective, randomized controlled trial. PMID- 29174252 TI - Prevalence and prognostic significance of left ventricular myocardial late gadolinium enhancement in severe aortic stenosis. AB - BACKGROUND: Myocardial fibrosis occurs in aortic stenosis (AS) as part of the hypertrophic response. It can be detected by LGE, which is associated with an adverse prognosis in the form of increased mortality and morbidity. OBJECTIVES: To assess the prevalence of LGE patterns using cardiac magnetic resonance (CMR) in severe AS patients and to study its prognostic significance. METHODS: Patients enrolled into the study from June 2012 to November 2014. All the patients underwent CMR and various patterns of LGE studied. These patients if symptomatic were advised AVR and others were managed conservatively. All patients were followed up and watched for outcomes like mortality, heart failure/hospitalization for cardiovascular cause, fall in left ventricular ejection fraction (LVEF) >=20% and arrhythmia. RESULTS: A total of 109 patients (mean age-57.7+/-12.5yrs) underwent CMR with 63 males. These patients were followed up for a mean of 13 months. Among 38 patients who underwent AVR, 6 died (5-cardiovascular cause, 1-non cardiovascular). 71 patients were managed conservatively out of which 18 died (17-cardiovascular cause, 1-non cardiovascular cause). LGE patterns were seen in 46 patients (43%); mid myocardial enhancement was seen in 31.1% of cases (33 patients). No LGE pattern was seen in 57%(63 patients). Basal and mid regions were maximally involved with mid myocardial enhancement in 66% & 68.3% respectively. LV ejection fraction (p=0.002), peak aortic systolic velocity (p=0.01) and peak aortic systolic gradient (p=0.02) were the main predictors of LGE. Main predictors of primary outcome were NYHA class [OR- 13.4(2.8-26.1), p<=0.001], age- 62+/- 9.6yrs(p=0.001), EF simpson-50.9+/-13%(p<= 0.001), LGE[OR 2.8 (1.27 6.47),p=0.01], number of segments involved [2.37+/-2.1,P<=0.001] & CMR LV mass (151.73+/-32gms, p=0.007). LGE predicted heart failure/hospitalization for cardiovascular cause [OR- 3.8(1.2-11.9), p=0.01] and fall in LVEF [OR- 5.8(1.5 22.5), p=0.005]. Patients with LGE had 2.87 times risk of adverse outcomes and patients with more than 3 segment LGE involvement had again increased chances for adverse outcomes. CONCLUSIONS: LGE was detected by CMR in 43% of patients with severe AS. It predicted recurrent heart failure, hospitalization for cardiovascular cause and fall in LV ejection fraction. Our study has laid a path to larger prospective studies with long term follow up to assess the prognostic impact of CMR in patients with severe AS. PMID- 29174253 TI - The association of the Syntax score II with carotid intima media thickness and epicardial fat tissue. AB - AIM: Syntax score II (SSII) is a highly predictive scoring system, which is used to improve individualized assessment of patients with complex coronary artery disease and facilitates clinical decision making. Surrogate markers [carotid intima-media thickness (CIMT), epicardial fat tissue (EFT)] are also used for risk assessment, but their relation with SSII is not well established. METHOD: We enrolled 543 consecutive patients, who underwent coronary angiography for stable angina pectoris and acute coronary syndrome, in the study. SSII was calculated for each patient and the patients were divided into two groups as low SSII group and high SSII group according to their median SSII. RESULTS: The average age of the patients was 61.4 years and 75% of the patients were male. The multivariate analysis indicated that only EFT (p: 0,035), CIMT (p:0,04) and Hypertension (HT) (p: 0,014) were independently associated with high SSII. DISCUSSION: EFT and CIMT, the surrogate markers which can be simply and non-invasively determined, are of the independent predictors of high SSII. The inclusion of these parameters in the risk classification may provide additional clinical benefit. PMID- 29174254 TI - "Correlation of red blood cell distribution width with the severity of coronary artery disease-A single center study". AB - OBJECTIVE: Coronary Artery Disease (CAD) is the leading cause of morbidity and mortality all around the world. We evaluated the correlation of Red blood cell Distribution Width (RDW) with the severity of lesion on coronary angiography as assessed by Modified Gensini score (MGS) in CAD patients. METHODS: A total of 576 consecutive patients admitted in Department of Cardiology over a period of one year, who underwent coronary angiography after diagnosis of CAD or presence of angina like chest pain and/or positive treadmill test were enrolled in the study (August 2014-May 2015). Patients were divided into two groups, with CAD (Group A) and without CAD (Group B). The RDW Cofficience of variance (RDW CV) and RDW standard deviatiton (RDW SD) of each patient, and their correlation with severity of CAD was assessed. RESULTS: Of the total 576 patients enrolled, 438 were in Group A and 138 were in Group B. The mean age of presentation in Group A and Group B was (53.64+/-10.36 vs 49.4+/-9.73)years (p<0.0001). The Male and Female ratio overall was 2.42:1. Patients in Group A had significantly elevated RDW CV and RDW SD levels compared with those in Group B [(14.59+/-1.04)% vs (13.6+/ 0.68)%, p<0.0001], [(45.78+/-4.76) vs (40.77+/-3.01), p<0.0001 respectively]. A significant positive correlation between RDW CV, RDW SD and MGS was noted (r=0.33, p<0.0001) (r=0.43, p<0.0001) respectively. On multivariate logistic regression analysis, RDW was demonstrated to be an independent predictor for angiographic CAD (OR=4.17, 95% CI 3.05-5.69, p<0.0001). On receiver operating characteristic curve (ROC) analysis, an RDW value of 14.3% was identified as an effective cut off point in diagnosing CAD with a sensitivity of 58.9% and specificity of 84.8%. CONCLUSIONS: RDW is an independent predictor of CAD and severity of coronary stenosis, suggesting that it can be a readily available marker for prediction and severity of CAD. PMID- 29174255 TI - The impact of severity of initial illness, determined by SOFA score, and presence of anemia on outcomes among patients requiring Extra Corporal Membrane Oxygenation (ECMO) support: A single center experience. AB - INTRODUCTION: ECMO provides respiratory and circulatory support in critically ill patients. In our study, we report on a single center experience with ECMO and aim to identify the prognostic markers for survival to discharge from hospital. METHODS: A registry was maintained on all patients who underwent ECMO implantation from September 2012 till January 2016 at a single institution. The collected data was analyzed to identify baseline characteristics, outcomes including clinical variables predictive of poor outcome. RESULTS: A total of 29 patients underwent ECMO implantation. The average age of patients was 42+/ 18years. 59% were males (N=17). 19 cases had a cardiac indication for ECMO (66%) while 10 cases had a pulmonary indication (34%). On univariate analysis; presence of Multi-organ failure, SOFA score more than 18 and hemoglobin less than 10g/dl at baseline and after ECMO removal were associated with increased 30day mortality. Pearson correlation with 30day mortality showed a positive correlation with MOF (+0.562, p=0.002) and SOFA score >18 (+0.448, p=0.015) and a negative correlation with anemia (-0.507, p=0.005). 15 out of the total 29 patients (52%) died within 30days of admission. Patients with MOF (log rank: 10.926, p=0.001), SOFA score >18 (log rank: 7.758, p=0.005) and hemoglobin <10g/dl (log rank: 5.595, p=0.018) had decreased survival on 30day follow up. CONCLUSIONS: Although the use of ECMO as a last line in the treatment of critical patients refractory to conventional treatment measures constitutes an important improvement in their care; with 48% overall survival; patient selection and timing of ECMO initiation remains challenging. Patients who already had signs of MOF and a high SOFA score portended a poor response. Similarly for anemic patients. Hence the importance of consideration for ECMO use earlier in course of illness rather than later. Screening and aggressive treatment of anemia in those patients may help improve the outcomes. PMID- 29174256 TI - Mid-term results of correction of Tetralogy of Fallot with absent pulmonary valve. AB - BACKGROUND: Tetralogy of Fallot and absent pulmonary valve (TOF/APV) is associated with significant pulmonary artery dilatation and airway compression. METHODS: We performed a retrospective review of 73 consecutive patients who underwent repair for TOF/APV between January 2005-August 2015. Mean age was 6.4+/ 5.6years (28days-22years). The right ventricular outflow tract (RVOT) was reconstructed using varied techniques. Freedom from RVOT gradients and re operation was studied. RESULTS: There were four (5.5%) early deaths, two each in infants and older children. Median ICU stay was 2days (range, 1-12days). Mean ICU stay for, infants, children and adults, was 6.5+/-6.04, 2.75+/-2.45, and 2.33+/ 1.03days, respectively (p=0.0762). Median hospital stay was 6days (range, 4 to 15days). Mean hospital stay for, infants and children and adults was 7+/-2, 6.75+/-2.39, and 6.33+/-1.63days, respectively (p=0.325). Mean follow up was 65+/ 36.6months (median 56 months, range 7-126 months). On follow up echocardiography, 14 (21.21%) had no pulmonary regurgitation. 21 (31.81%) had mild PR patients, 8 (12.12%) moderate PR and 19 (28.78%) had severe PR. There were five (7.5%) reoperations. Five and ten-year survival was 95%+/-2.12 and 92.3%+/-3.45 respectively. Freedom from RVOT reoperation was 93+/-2.62% and 89+/-3.87% at 5 and 10 years. CONCLUSIONS: In contrast to children and adults with TOF/APV, infants carry significant early mortality. But the mid-term outcome for patients who survive the initial repair of TOF/APV is acceptable. However, these patients require constant surveillance and irrespective of the methods of RVOT management, the reoperation rates are expected to be high as more of these patients survive into adulthood. PMID- 29174257 TI - Use of nitroglycerin and verapamil solution by organ bath technique in preparation of left internal thoracic artery for coronary artery bypass surgery. AB - BACKGROUND: The aim of this prospective study was to compare the effect of application of nitroglycerin and verapamil solution (GV) by organ bath technique with other methods of applications and solutions on the free blood flow of LITA. The technique was not described for in situ graft before. METHOD: The patients were randomly assigned to four groups: group I (n_32, GV solution by organ bath technique), group II (n_30, papaverine solution by organ bath technique), group III (n_29, topical GV solution) or group IV (n_29, topical papaverine solution). In each patient, pedicled LITA was harvested; thereafter applied with the randomized different methods and solutions. The free flow from the distal end of the divided LITA was measured for 15s under controlled hemodynamic conditions after harvesting (Flow 1). The flow of LITA was measured again just prior to anastomosing the conduit (Flow 2). RESULT: The mean blood flow in LITA was 56.2+/ 5.0ml/min before application of solutions. After application, the mean blood flow in group I:102.3+/-7.0ml/min, in group II: 92.7+/-3.4ml/min, and in group III: 88.6+/-2.2ml/min and in group IV: 81.4+/-2.1. Proportional increases in blood flow observed in group I (82.6%)>group II (65.1%)>group III (57.6)>group IV (44.8%) (p<0.05). CONCLUSIONS: GV solution by organ bath technique is effective and superior in comparison to use of papaverine using organ bath technique or topical spray of GV or papaverine solution. PMID- 29174258 TI - The design and rationale of the primary angioplasty registry of Kerala. AB - BACKGROUND: ST-elevation myocardial infarction (STEMI) continues to be a major cause of cardiovascular mortality in Kerala, India. Timely primary percutaneous coronary intervention (PCI) is the recommended reperfusion strategy for STEMI. There is limited data on the safety, effectiveness, equity and efficiency of regional primary PCI services in India. METHODS/DESIGN: The primary angioplasty registry of Kerala is a clinician-initiated prospective state-wide longitudinal hospital-based registry of patients undergoing primary PCI for STEMI. The registry aims to document the efficacy and safety of the real world use of primary PCI in Indian patients presenting with STEMI, in order to achieve regional adoption of global standard performance indicators. In addition, the registry would analyze procedural variations in the performance of primary PCI and assess its impact on relevant patient centered outcomes. We plan to enroll 6000 STEMI patients, undergoing primary PCI, across 48 hospitals. These patients would be followed up for a minimum of 1year. CONCLUSIONS: The primary angioplasty registry of Kerala would help analyze the quality and outcomes of primary PCI services in Kerala, thereby yielding insights that can help limit unacceptable procedural variations in the performance of primary PCI. Identifying deviations from guideline based therapies can form the basis of quality improvement programs, which in turn will enable hospitals to achieve better patient outcomes. PMID- 29174259 TI - Cardiac cachexia in sub-Saharan Africa. AB - Cachexia is a public health challenge around the Globe but data on prevalence rates in developing countries are very scarce. In sub-Saharan Africa wasting syndrome is mainly related to malaria, HIV infections, tuberculosis and end-stage heart disease and always associated with high-mortality and dismal quality of life regardless of age, urban or rural setting. We report two different cases affected by cardiac cachexia related to end-stage heart disease. The large age gap between patients highlights the current impact of medical services in Uganda ranging from low-resource rural settings to urban areas of the capital city under epidemiologic transition. The wasting syndrome occurring in both patients emphasizes as cachexia remains largely neglected and underestimated in most sub Saharan African countries.

PMID- 29174261 TI - Know thy neighbors: The status of cardiac surgery in the South Asian countries around India. AB - OBJECTIVES: The South Asian neighboring countries of India include Bangladesh, Bhutan, Nepal, The Maldives, Pakistan and Sri Lanka. Interestingly all these countries possess either a land or a sea border with India and no border among themselves. These countries have historic, cultural, ethnic and genetic links with India. The paper describes the developmental history and current status of cardiac surgery in these countries. METHODS: Thorough search of the printed and electronic materials has been made. The authors visited all these countries and contacted the eminent surgeons personally or through mails. All the information is cross-checked and compiled. Record keeping is not well organized in most of these countries. Best information often came from unusual sources like Anesthetists' society or the corporate houses. RESULTS: Four of these countries Bangladesh, Nepal, Pakistan and Sri Lanka have their cardiac surgical programs. Collectively they perform around 38000 cardiac operations a year which is a quarter of the cases performed in India. These countries are important sources of medical tourism in India which is worth 3 billion US$ of business annually. CONCLUSION: When the number of operations per million populations is considered, Bangladesh and Nepal are lagging behind India where as Pakistan has a comparable figure. Sri Lanka with 265 cardiac operations/million populations has the best figures in the region. However when compared with the Western countries even the Lankan figures also look quite inadequate. PMID- 29174262 TI - Perioperative plasma mitochondrial DNA dynamics and correlation with inflammation during infantile cardiopulmonary bypass. AB - OBJECTIVE: Numerous studies in animals and humans have demonstrated that inflammatory mediators such as tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and IL-8 play a role in cardiopulmonary bypass (CPB), which might affect surgical outcomes. Plasma mitochondrial DNA (mtDNA), a recently discovered pro inflammatory agent, is released by cells upon insult. This study aimed to detect changes in plasma mtDNA levels at different time points after infantile CPB and explore its potential association with inflammatory mediators. METHODS: In the present study, we analyzed the perioperative plasma mtDNA and inflammatory cytokine levels of 48 infants undergoing ventricular septal defect closure. Blood samples were collected before aortic cross-clamping (T1), at the end of CPB (T2), and 6h (T3), 12h (T4), and 24h (T5) post-CPB. Reverse transcription-polymerase chain reaction and specific enzyme-linked immunosorbent assay were used to quantify the plasma mtDNA and inflammatory cytokines, respectively. Bivariate correlation analysis was used to determine the correlations between plasma mtDNA and inflammatory cytokines. RESULTS: Plasma mtDNA levels increased at T2 and peaked at T3. Significant positive correlations were found between peak plasma mtDNA (at T3) and several inflammatory biomarkers, including IL-6 (at T3) (r=0.62, P<0.001), IL-8 (at T2) (r=0.53, P<0.001), and TNF-alpha (at T3) (r=0.61, P<0.001). CONCLUSION: Here we report that mtDNA may participate in a systemic inflammatory response to CPB. PMID- 29174263 TI - First ever transmitral valve in valve replacement in India.

PMID- 29174270 TI - Are e-cigarettes beneficial for public health: Hume's guillotine - The debate continues? AB - Cigarette smoking is the most common preventable cause of death which has led to a search for healthier alternatives to tobacco smoke. Electronic cigarettes are devoid of many harmful constituents found in cigarette smoke and are therefore being positioned as safer alternative to tobacco smoke. The carcinogenic potential may be of lower magnitude compared with cigarette smoke, but it is still there. The use of e-cigarettes, however, is fairly new, so its long-term effects are still unknown. Moreover, they continue to posses the cardiovascular side-effects and are certainly as addicting. Thus on one hand while their substitution could lead to reduction of some side-effects of tobacco smoke, its use may be just shifting the modality of addiction and will be unlikely to lead to total abstinence from tobacco products. On the other hand there is a fear that its use could lead to loosening of the taboo currently associated with use of tobacco products and so the benefits of years of advocacy to ban tobacco products might be lost. Thus currently the scientific community is divided about role of e cigarettes. PMID- 29174272 TI - Editorial Comment.

AB - BACKGROUND: Rotator cuff tears affect millions of individuals each year, often requiring surgical intervention. However, repair failure remains common. We have previously shown that pulsed electromagnetic field (PEMF) therapy improved tendon to-bone healing in a rat rotator cuff model. The purpose of this study was to determine the influence of both PEMF frequency and exposure time on rotator cuff healing. METHODS: Two hundred ten Sprague-Dawley rats underwent acute bilateral supraspinatus injury and repair followed by either Physio-Stim PEMF or high frequency PEMF therapy for 1, 3, or 6 hours daily. Control animals did not receive PEMF therapy. Mechanical and histologic properties were assessed at 4, 8, and 16 weeks. RESULTS: Improvements in different mechanical properties at various endpoints were identified for all treatment modalities when compared with untreated animals, regardless of PEMF frequency or duration. Of note, 1 hour of Physio-Stim treatment showed significant improvements in tendon mechanical properties across all time points, including increases in both modulus and stiffness as early as 4 weeks. Collagen organization improved for several of the treatment groups compared with controls. In addition, improvements in type I collagen and fibronectin expression were identified with PEMF treatment. An important finding was that no adverse effects were identified in any mechanical or histologic property. CONCLUSIONS: Overall, our results suggest that PEMF therapy has a positive effect on rat rotator cuff healing for each electromagnetic fundamental pulse frequency and treatment duration tested in this study.

AB - BACKGROUND: Human maternal placentophagy is gaining popularity among a growing number of women who believe it provides maternal benefits, including prevention of postpartum blues/depression, improved maternal bonding, and reduced fatigue. METHODS: We conducted a randomized, double-blind, placebo-controlled pilot study (N=27) in which participants consumed either their processed, encapsulated placenta (n=12), or similarly prepared placebo (n=15). Maternal mood, bonding, and fatigue were assessed via validated scales across four time points during late pregnancy and early postpartum. Psychometric data were analyzed for changes between and within both groups over time. RESULTS: No significant main effects related to maternal mood, bonding, or fatigue were evident between placenta and placebo group participants. However, examination of individual time points suggested that some measures had specific time-related differences between placenta and placebo groups that may warrant future exploration. Though statistical significance should not be interpreted in these cases, we did find some evidence of a decrease in depressive symptoms within the placenta group but not the placebo group, and reduced fatigue in placenta group participants at the end of the study compared to the placebo group. CONCLUSIONS: No robust differences in postpartum maternal mood, bonding, or fatigue were detected between the placenta and placebo groups. This finding may be especially important for women considering maternal placentophagy as a 'natural' (i.e., non pharmacological) means of preventing or treating blues/depression. Given the study limitations, these findings should be interpreted as preliminary. Small, time-related improvements in maternal mood and lower fatigue post-supplementation among placenta group participants may warrant further research. PMID- 29174274 TI - Effects of placentophagy on maternal salivary hormones: A pilot trial, part 1. AB - BACKGROUND: Recent studies show that human placenta, processed and encapsulated for postpartum consumption, contains a host of trace minerals and hormones that could conceivably affect maternal physiology. Our objective was to investigate whether salivary hormone concentrations of women ingesting their own encapsulated placenta during the early postpartum differed from those of women consuming a placebo. METHODS: Randomly assigned participants (N=27) were given a supplement containing either their dehydrated and homogenized placenta (n=12), or placebo (n=15). Saliva samples were collected during late pregnancy and early postpartum. Samples of participants' processed placenta, and the encapsulated placebo, were also collected. Hormone analyses were conducted on all samples utilizing liquid chromatography-tandem mass spectrometry. RESULTS: There were no significant differences in salivary hormone concentrations between the placenta and placebo groups post-supplementation that did not exist pre-supplementation. There were, however, significant dose-response relationships between the concentration of all 15 detected hormones in the placenta capsules and corresponding salivary hormone measures in placenta group participants not seen in the placebo group. The higher salivary concentrations of these hormones in the placenta group reflects the higher concentrations of these hormones in the placenta supplements, compared to the placebo. CONCLUSIONS: Some hormones in encapsulated placenta lead to small but significant differences in hormonal profiles of women taking placenta capsules compared to those taking a placebo, although these dose-response changes were not sufficient to result in significant hormonal differences between groups. Whether modest hormonal changes due to placenta supplementation are associated with therapeutic postpartum effects, however, awaits further investigation.

AB - OBJECTIVE: To analyze the relationship between the sense of coherence and subjective overload, anxiety and depression in caregivers of dependent elderly relatives. METHOD: Cross-sectional study in an area of the province of Jaen (Andalusia, Spain) with a probabilistic sample of 132 caregivers of dependent elderly. MAIN MEASURES: sense of coherence (Life Orientation Questionnaire), subjective burden (Caregiver Strain Index), anxiety and depression (Goldberg Scale), objective burden (Dedication to Care Scale), sex and kinship. Main analyses: bivariate analysis using the Pearson correlation coefficient and multivariate analysis using multiple linear regression. RESULTS: Most of the caregivers studied were women (86.4%), daughter or son of the care recipient (74.2%) and shared home with the latter (69.7%). When controlling for objective burden, sex and kinship, we found that the sense of coherence was inversely related to subjective burden (beta = -0.46; p <0.001), anxiety (beta = -0.57; p = 0.001) and depression (beta = -0.66; p <0.001). CONCLUSIONS: The sense of coherence might be an important protective factor of subjective burden, anxiety and depression in caregivers of dependent elderly relatives.

PMID- 29174280 TI - Physician staffing needs in critical care departments. AB - Departments of Critical Care Medicine are characterized by high medical assistance costs and great complexity. Published recommendations on determining the needs of medical staff in the DCCM are based on low levels of evidence and attribute excessive significance to the structural/welfare approach (physician-to beds ratio), thus generating incomplete and minimalistic information. The Spanish Society of Intensive Care Medicine and Coronary Units established a Technical Committee of experts, the purpose of which was to draft recommendations regarding requirements for medical professionals in the ICU. The Technical Committee defined the following categories: 1) Patient care-related aspects; 2) Activities outside the ICU; 3) Patient safety and clinical management aspects; 4) Teaching; and 5) Research. A subcommittee was established with experts pertaining to each activity category, defining criteria for quantifying the percentage time of the intensivists dedicated to each task, and taking into account occupational category. A quantitative method was applied, the parameters of which were the number of procedures or tasks and the respective estimated indicative times for patient care-related activities within or outside the context of the DCCM, as well as for teaching and research activities. Regarding non-instrumental activities, which are more difficult to evaluate in real time, a matrix of range versus productivity was applied, defining approximate percentages according to occupational category. All activities and indicative times were tabulated, and a spreadsheet was created that modified a previously designed model in order to perform calculations according to the total sum of hours worked and the hours stipulated in the respective work contract. The competencies needed and the tasks which a Department of Critical Care Medicine professional must perform far exceed those of a purely patient care-related character, and cannot be quantified using structural criteria. The method for describing the 5 types of activity, the quantification of specific tasks, the respective times needed for each task, and the generation of a spreadsheet led to the creation of a management instrument. PMID- 29174281 TI - Controversies and recommendations regarding sentinel lymph node biopsy in primary breast cancer: A comprehensive review of current data. AB - In primary breast cancer, sentinel lymph node biopsy has been established as the gold standard for regional axillary staging. A robust body of randomized data support its accuracy and safety in patients with early, clinically node negative disease. However, the role of SLNB remains debatable in various patient subgroups, and recent advances in histopathology, dedicated axillary ultrasound imaging and chemotherapy regimens, put its role under a new perspective. Herein, we review the current literature data on the indications for SLNB and discuss the challenges in management germane to special patient subgroups and patterns of disease. We also present emerging data on the optimal management of the SLN+ patient, in light of recent trials challenging the dogma of completion axillary dissection after a positive sentinel node biopsy. PMID- 29174282 TI - Intranasal dexmedetomidine in termination of first trimester pregnancy of suction evacuation. AB - BACKGROUND AND AIM: Deep sedation without intubation for termination of first trimester pregnancy of suction evacuation entails use of sedatives such as propofol or a combination of propofol and sulfentanil, with unwanted complications. Dexmedetomidine is an alpha2-adrenoreceptor agonist which provides sedation, anxiolysis and analgesia, without any of the complications associated with the popular sedatives. METHODS: A total number of 90 patients were randomized to three groups: 1. group P, treated with intranasal saline, intravenous saline and propofol; 2. group DP, treated with intranasal dexmedetomidine, intravenous saline and propofol; and 3. group SP, treated with intranasal saline, intravenous sulfentanil and propofol. The primary outcome was the consumption of propofol, and the secondary outcomes were numeric rating scale (NRS) anxiety score, NRS pain score of uterine cramping, amount of blood loss, use of oxytocin and NRS satisfaction scores of obstetric and gynecological (ob/gyn) physicians and patients. RESULTS: The consumption of propofol, NRS pain score of uterine cramping after surgery, NRS anxiety score, and amount of blood loss in group DP were significantly lower than those in group P and group SP. Ob/gyn physicians' satisfaction score in group DP was significantly higher compared with group SP and group P. CONCLUSION: Sedation with intranasal dexmedetomidine (1 MUg/kg) provided effective analgesia and anxiolysis, reduced consumption of propofol and lower blood loss in termination of first trimester pregnancy of suction evacuation. Compared with propofol or the combination of propofol and sulfentanil, intranasal dexmedetomidine was associated with higher satisfaction score of ob/gyn physicians. No unforeseen perioperative respiratory and cardiovascular adverse events occurred. REGISTRY NUMBER FOR CLINICAL TRIALS: ChiCTR-IPR-14005654.

AB - The mammalian heme peroxidases including lactoperoxidase (LPO), myeloperoxidase (MPO), eosinophil peroxidase (EPO) and thyroid peroxidase (TPO) contain a covalently linked heme moiety. Initially, it was believed that the heme group was fully cross-linked to protein molecule through at least two ester linkages involving conserved glutamate and aspartate residues with 1-methyl and 5-methyl groups of pyrrole rings A and C respectively. In MPO, an additional sulfonium ion linkage was present between 2-vinyl group of pyrrole ring A of the heme moiety and a methionine residue of the protein. These linkages were formed through a self processing mechanism. Subsequently, biochemical studies indicated that the heme moiety was partially attached to protein. The recent structural studies have shown that the covalent linkage involving glutamate and 1-methyl group of pyrrole ring of heme moiety was partially formed. When glutamate is not covalently linked to heme moiety, its side chain occupies a position in the substrate binding site on the distal heme side and blocks the substrate binding site leading to inactivation. However, an exposure to H2O2 converts it to a fully covalently linked state with heme. Thus in mammalian heme peroxidases, the Glu-heme linkage is essential for catalytic action. PMID- 29174285 TI - Longitudinal association among endothelial function, arterial stiffness and subclinical organ damage in hypertension. AB - OBJECTIVES: To examine the longitudinal mutual association between endothelial dysfunction and arterial stiffness, and also to determine which of the two variables was more closely associated with the progression of subclinical organ damage. METHODS: The brachial-ankle pulse wave velocity (baPWV), carotid intima media thickness (CIMT), estimated glomerular filtration rate, microalbuminuria and flow-mediated vasodilatation of the brachial artery (FMD) were measured three times at 1.5-year intervals in 674 Japanese patients receiving antihypertensive treatment. RESULTS: The change of the baPWV during the study period was larger in the subjects with baseline FMD values in the lowest tertile as compared to those with baseline FMD values in the highest tertile. The change of the CIMT was smaller in the subjects with baseline baPWV values in the lowest tertile than in those with baseline baPWV values in the highest tertile. After the adjustment, the FMD value at the baseline was inversely associated with the baPWV at the end of the study period (beta=-0.07, p=0.01), although, the reverse association was not significant. The baPWV, but not the FMD value, at the baseline was associated with the CIMT (beta=0.06, p=0.04) measured at the end of the study period. CONCLUSIONS: In hypertension, endothelial dysfunction was associated with the progression of arterial stiffness, although the reverse association was not confirmed. The increased arterial stiffness rather than endothelial dysfunction may be more closely associated with the progression of atherosclerotic vascular damage, and the endothelial dysfunction-arterial stiffness-atherosclerosis continuum may be important in hypertension. PMID- 29174287 TI - On the use of on-cow accelerometers for the classification of behaviours in dairy barns. AB - Analysing behaviours can provide insight into the health and overall well-being of dairy cows. Automatic monitoring systems using e.g., accelerometers are becoming increasingly important to accurately quantify cows' behaviours as the herd size increases. The aim of this study is to automatically classify cows' behaviours by comparing leg- and neck-mounted accelerometers, and to study the effect of the sampling rate and the number of accelerometer axes logged on the classification performances. Lying, standing, and feeding behaviours of 16 different lactating dairy cows were logged for 6h with 3D-accelerometers. The behaviours were simultaneously recorded using visual observation and video recordings as a reference. Different features were extracted from the raw data and machine learning algorithms were used for the classification. The classification models using combined data of the neck- and the leg-mounted accelerometers have classified the three behaviours with high precision (80-99%) and sensitivity (87-99%). For the leg-mounted accelerometer, lying behaviour was classified with high precision (99%) and sensitivity (98%). Feeding was classified more accurately by the neck-mounted versus the leg-mounted accelerometer (precision 92% versus 80%; sensitivity 97% versus 88%). Standing was the most difficult behaviour to classify when only one accelerometer was used. In addition, the classification performances were not highly influenced when only X, X and Z, or Z and Y axes were used for the classification instead of three axes, especially for the neck-mounted accelerometer. Moreover, the accuracy of the models decreased with about 20% when the sampling rate was decreased from 1Hz to 0.05Hz. PMID- 29174288 TI - [Update on the respiratory management of patients with chronic neuromuscular disease]. AB - BACKGROUND: Neuromuscular diseases include a wide range of conditions that may involve potentially life-threatening respiratory complications (infection, respiratory failure). SURVEILLANCE AND PULMONARY FUNCTION TESTS: For patients with neuromuscular diseases, clinical assessment of respiratory function and regular pulmonary function tests are needed to screen for nocturnal respiratory disorders, weakness of the diaphragm and potential restrictive disorders and/or chronic hypercapnic respiratory insufficiency, possibly with couch deficiency. MANAGEMENT OF NOCTURNAL RESPIRATORY DISORDERS AND CHRONIC RESPIRATORY FAILURE: Nocturnal respiratory assistance is an important phase of care for nocturnal respiratory disorders and chronic respiratory failure. This may involve continuous positive airway pressure, adaptative servo-ventilation or non-invasive ventilation with a facial or nasal mask. As needed, diurnal assistance may be proposed by mouthpiece ventilation. Should non-invasive ventilation prove insufficient, or if significant swallowing disorders or recurrent bronchial obstruction develop, or in case of prolonged intubation, tracheotomy may be required. LOWER AIRWAY OBSTRUCTION: In case of lower airway infection with ineffective cough, physical therapy, associated with air stacking, intermittent positive pressure breathing or mechanical in-exsufflation may be proposed. PATIENT-CENTERED MANAGEMENT: Care for swallowing disorders, nutritional counseling (cachexia, obesity), vaccinations and therapeutic education are integral elements of patient-centered management aiming to prevent the negative impact of infection and to manage respiratory failure of chronic neuromuscular disease. PMID- 29174289 TI - Derivation and Validation of the Emergency Medical Stroke Assessment and Comparison of Large Vessel Occlusion Scales. AB - BACKGROUND: This study aims to develop a simple scale to identify patients with prehospital stroke with large vessel occlusion (LVO), without losing sensitivity for other stroke types. METHODS: The Emergency Medical Stroke Assessment (EMSA) was derived from the National Institutes of Health Stroke Scale (NIHSS) items and validated for prediction of LVO in a separate cohort. We compared the EMSA with the 3-item stroke scale (3I-SS), Cincinnati Prehospital Stroke Severity Scale (C STAT), Rapid Arterial oCclusion Evaluation (RACE) scale, and Field Assessment Stroke Triage for Emergency Destination (FAST-ED) for prediction of LVO and stroke. We surveyed paramedics to assess ease of use and interpretation of scales. RESULTS: The combination of gaze preference, facial asymmetry, asymmetrical arm and leg drift, and abnormal speech or language yielded the EMSA. An EMSA less than 3, 75% sensitivity, and 50% specificity significantly reduced the likelihood of LVO (LR- = .489, 95% confidence interval .366-0.637) versus 3I SS less than 4 (.866, .798-0.926). A normal EMSA, 93% sensitivity, and 47% specificity significantly reduced the likelihood of stroke (LR- = .142, .068 0.299) versus 3I-SS (.476, .330-0.688) and C-STAT (.858, .717-1.028). EMSA was rated easy to perform by 72% (13 of 18) of paramedics versus 67% (12 of 18) for FAST-ED and 6% (1 of 18) for RACE (chi2 = 27.25, P < .0001), and easy to interpret by 94% (17 of 18) versus 56% (10 of 18) for FAST-ED and 11% (2 of 18) for RACE (chi2 = 21.13, P < .0001). CONCLUSIONS: The EMSA has superior abilities to identify LVO versus 3I-SS and stroke versus 3I-SS and C-STAT. The EMSA has similar ability to triage patients with stroke compared with the FAST-ED and RACE, but is simpler to perform and interpret. PMID- 29174290 TI - Associations of Mitral and Aortic Valve Calcifications with Complex Aortic Atheroma in Patients with Embolic Stroke of Undetermined Source. AB - BACKGROUND: This study investigated the associations of mitral and aortic valve calcification with complex aortic atheroma among patients with embolic stroke of undetermined source. METHODS: We included 52 consecutive patients (mean age 58.1 years; 75.0% male) with embolic stroke of undetermined source. Mitral annular calcification, aortic annular calcification, and aortic valve sclerosis were assessed by transthoracic echocardiography. Complex aortic atheroma was assessed by transesophageal echocardiography and was defined as plaque protruding greater than or equal to 4 mm into the lumen or with ulcerated or mobile components. RESULTS: Ten patients (19.2%) had complex aortic atheroma. Patients with and without complex aortic atheroma showed significant differences in terms of hypertension (80.0% versus 38.1%, P = .017), dyslipidemia (90.0% versus 31.0%, P <.01), chronic kidney disease (60.0% versus 14.3%, P <.01), previous coronary artery disease (30.0% versus 4.8%, P = .013), prior stroke (40.0% versus 7.1%, P <.01), left atrial dimension (4.0 cm versus 3.6 cm, P = .023), aortic valve sclerosis (80.0% versus 26.2%, P <.01), aortic valve calcification (aortic annular calcification or aortic valve sclerosis) (80.0% versus 26.0%, P <.01), and left-sided valve calcification (mitral annular calcification or aortic annular calcification or aortic valve sclerosis) (80.0% versus 28.6%, P <.01). In multivariate analysis, left-sided valve calcification was independently associated with complex aortic atheroma (odds ratio 4.1, 95% confidence interval 1.3-26.1, P = .049). CONCLUSIONS: Mitral or aortic valve calcification detected by transthoracic echocardiography can be a useful marker for predicting complex aortic atheroma in patients with embolic stroke of undetermined source.

AB - Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, affects millions of individuals around the world. Although it has been known for more than a century, the study of T. cruzi has been a challenge, particularly due to the scarcity of tools for genome inquiries. Recently, strategies have been described allowing gene disruption in T. cruzi by the CRISPR/Cas9 nuclease system. Although these strategies demonstrated success in deleting some genes, several aspects could be improved to increase the efficiency of the CRISPR/Cas9 system in T. cruzi. Here, we report a strategy, based on adaptations and improvements of the two previously described systems, that results in efficient gene disruption that can be applied to any target, including the study of essential genes. PMID- 29174292 TI - Temporal trends and patterns in heart failure incidence: a population-based study of 4 million individuals. AB - BACKGROUND: Large-scale and contemporary population-based studies of heart failure incidence are needed to inform resource planning and research prioritisation but current evidence is scarce. We aimed to assess temporal trends in incidence and prevalence of heart failure in a large general population cohort from the UK, between 2002 and 2014. METHODS: For this population-based study, we used linked primary and secondary electronic health records of 4 million individuals from the Clinical Practice Research Datalink (CPRD), a cohort that is representative of the UK population in terms of age and sex. Eligible patients were aged 16 years and older, had contributed data between Jan 1, 2002, and Dec 31, 2014, had an acceptable record according to CPRD quality control, were approved for CPRD and Hospital Episodes Statistics linkage, and were registered with their general practice for at least 12 months. For patients with incident heart failure, we extracted the most recent measurement of baseline characteristics (within 2 years of diagnosis) from electronic health records, as well as information about comorbidities, socioeconomic status, ethnicity, and region. We calculated standardised rates by applying direct age and sex standardisation to the 2013 European Standard Population, and we inferred crude rates by applying year-specific, age-specific, and sex-specific incidence to UK census mid-year population estimates. We assumed no heart failure for patients aged 15 years or younger and report total incidence and prevalence for all ages (>0 years). FINDINGS: From 2002 to 2014, heart failure incidence (standardised by age and sex) decreased, similarly for men and women, by 7% (from 358 to 332 per 100 000 person-years; adjusted incidence ratio 0.93, 95% CI 0.91-0.94). However, the estimated absolute number of individuals with newly diagnosed heart failure in the UK increased by 12% (from 170 727 in 2002 to 190 798 in 2014), largely due to an increase in population size and age. The estimated absolute number of prevalent heart failure cases in the UK increased even more, by 23% (from 750 127 to 920 616). Over the study period, patient age and multi-morbidity at first presentation of heart failure increased (mean age 76.5 years [SD 12.0] to 77.0 years [12.9], adjusted difference 0.79 years, 95% CI 0.37-1.20; mean number of comorbidities 3.4 [SD 1.9] vs 5.4 [2.5]; adjusted difference 2.0, 95% CI 1.9 2.1). Socioeconomically deprived individuals were more likely to develop heart failure than were affluent individuals (incidence rate ratio 1.61, 95% CI 1.58 1.64), and did so earlier in life than those from the most affluent group (adjusted difference -3.51 years, 95% CI -3.77 to -3.25). From 2002 to 2014, the socioeconomic gradient in age at first presentation with heart failure widened. Socioeconomically deprived individuals also had more comorbidities, despite their younger age. INTERPRETATION: Despite a moderate decline in standardised incidence of heart failure, the burden of heart failure in the UK is increasing, and is now similar to the four most common causes of cancer combined. The observed socioeconomic disparities in disease incidence and age at onset within the same nation point to a potentially preventable nature of heart failure that still needs to be tackled.

AB - The excitability of dopaminergic neurons in the substantia nigra pars compacta (SNc) that supply the striatum with dopamine (DA) determines the function of the nigrostriatal system for motor coordination. We previously showed that 4 pyridinylmethyl-9(10H)-anthracenone (XE991), a specific blocker of Kv7/KCNQ channels, enhanced the excitability of nigral DA neurons and resulted in attenuation of haloperidol-induced catalepsy in a Parkinson's disease (PD) rat model. However, whether XE991 exhibits neuroprotective effects towards DA neuron degeneration remains unknown. The aim of this study was to investigate the effects of Kv7/KCNQ channel blocker, XE991, on 6-hydroxydopamine (6-OHDA)-induced nigral DA neuron degeneration and motor dysfunction. Using immunofluorescence staining and western blotting, we showed that intracerebroventricular administration of XE991 prevented the 6-OHDA-induced decrease in tyrosine hydroxylase (TH)-positive neurons and TH protein expression in the SNc. High performance liquid chromatography with electrochemical detection (HPLC-ECD) also revealed that XE991 partly restored the levels of DA and its metabolites in the striatum. Moreover, XE991 decreased apomorphine (APO)-induced contralateral rotations, enhanced balance and coordination, and attenuated muscle rigidity in 6 OHDA-treated rats. Importantly, all neuroprotective effects by XE991 were abolished by co-application of Kv7/KCNQ channel opener retigabine and XE991. Thus, Kv7/KCNQ channel inhibition by XE991 can exert neuroprotective effects against 6-OHDA-induced degeneration of the nigrostriatal DA system and motor dysfunction.

AB - PURPOSE: The Icare(r) Home tonometer is a new rebound tonometer, developed for intraocular pressure (IOP) self-monitoring. The main objective of our study was to evaluate the reliability and reproducibility of measurements taken with the Icare(r) Home tonometer in glaucoma patients compared to the Goldmann applanation tonometer. A secondary objective was to investigate factors that could influence the reproducibility of these measurements. MATERIALS AND METHODS: Fifty-two glaucoma patients were included in this prospective, non-randomized, monocentric study. IOP measurements were performed on the right eye and then on the left eye in the following order (3 measurements of IOP for each method): air tonometer (T Air), Icare(r) Home tonometer by the patient (RT-P), Icare(r) Home tonometer by an ophthalmologist (RT-O), Goldmann applanation tonometer (GAT). RESULTS: Forty four patients (85%) managed to take their IOP on both eyes with the Icare(r) Home tonometer. Mean IOPs were 14.35+/-3.93mmHg (T-Air), 13.43+/-4.65mmHg (RT-P), 14.13+/-4.29mmHg (RT-O), 14.74+/-3.84mmHg (GAT). The intraclass correlation indices (ICC) on the 3 repeated IOP measurements were 0.924, 0.872, 0.947 and 0.957, respectively. Bland-Altman analysis found a mean difference (bias) between GAT and RT-P, between GAT and RT-O, and between RT-O and RT-P, respectively, of 1.31, 0.61 and 0.70mmHg, with a 95% confidence interval of -3.34 to 5.96, -3.91 to 5.14 and -3.44 to 4.84mmHg, respectively. The reproducibility of the measurements taken with the Icare(r) Home tonometer did not vary according to corneal thickness or age of the patients. CONCLUSION: The Icare(r) Home tonometer provides reliable and reproducible IOP values in glaucoma patients, although it appears to slightly underestimate the IOP measurements compared to the Goldmann applanation tonometer.

PMID- 29174299 TI - How do professional Australian Football League (AFL) players utilise social media during periods of injury? A mixed methods analysis. AB - OBJECTIVES: The objective of this study was to explore how social media is used by a population of injured professional athletes, by comparing the content and frequency of posts on social media, pre and post-injury. DESIGN: A retrospective mixed methods design was utilised. METHODS: Professional Australian Football League (AFL) players, injured during the 2015 season, were included in the study. Publicly accessible social media profiles for these players were identified on Twitter and Instagram. All posts published on verified profiles, from four weeks prior to injury until return to play, were extracted. Thematic analysis was used to investigate the content of these posts, while univariate and multivariate linear regression was used to investigate the frequency of posts during this time period. RESULTS: Two reoccurring themes were identified exclusively post-injury; 'supporting team from the sideline' and 'sharing information about injury and rehabilitation'. The frequency of total posts did not differ significantly pre and post-injury, but the frequency of injury related posts increased in the immediate post-injury phase, then decreased between 4-8 weeks and 8-12 weeks post injury. The frequency of injury related posts was higher with more severe injuries. CONCLUSIONS: The findings of this study suggest that injured players use social media to seek social support from their followers, especially in the immediate post-injury period and after sustaining a severe injury. The role of social media in injury rehabilitation may warrant further investigation, to determine if it could be used to facilitate return to play.

We studied the effects of metformin on serum levels of methylmalonic acid (MMA), a biomarker for tissue B12 deficiency, and on onset or progression of neuropathy. METHODS: In the HOME trial, 390 insulin-treated patients with type 2 diabetes were treated with metformin or placebo for 52months. In a post hoc analysis, we analyzed the association between metformin, MMA and a validated Neuropathy Score (NPS). RESULTS: Metformin vs placebo increased MMA at the end of the study (95%CI: 0.019 to 0.055, p=0.001). Mediation analysis showed that the effect of metformin on the NPS consisted of a beneficial effect through lowering HbA1c (-0.020 per gram year) and an adverse effect through increasing MMA (0.042 per gram year), resulting in a non-significant net effect (0.032 per gram year, 95% CI: -0.121 to 0.182, p=0.34). CONCLUSION: Metformin not only reduces serum levels of B12, but also progressively increases serum MMA. The increase of MMA in metformin users was associated with significant worsening of the NPS. These results provide further support that metformin-related B12 deficiency is clinically relevant. Monitoring of B12 in users of metformin should be considered. PMID- 29174301 TI - Dynamic changes in retinal vessel diameter during acute hyperglycemia in type 1 diabetes. AB - AIMS: To investigate changes in retinal vessel diameter during acute hyperglycemia in patients with type 1 diabetes. METHODS: We conducted a study on 11 subjects with type 1 diabetes. Euglycemia was maintained for 3h followed by induction of hyperglycemia and simultaneous bolus of rapid acting insulin. Two fundus photos were captured during euglycemia and five fundus photos, blood glucose and blood pressure were taken every 30min for 2.5h post-prandial. Central retinal artery equivalent (CRAE) and central retinal vein equivalent (CRVE) were measured over the study visit and examined using generalized linear mixed models. RESULTS: In a multivariate mixed model, mean CRAE and CRVE were reduced at 90min post-prandial in both zones B and C. In repeated measures analysis, arterioles exhibited a significant association with change in vessel caliber per change in blood glucose. Inconsistent effects of blood pressure on vessel diameter were also measured. CONCLUSIONS: We document a change in retinal vessel diameter during acute hyperglycemia in persons with type 1 diabetes. Larger controlled studies are required to further investigate this phenomenon and to more accurately assess if hyperglycemia has direct effects on retinal vessel diameter. PMID- 29174302 TI - The interaction of pulse width and current intensity on the extent of cortical plasticity evoked by vagus nerve stimulation. AB - BACKGROUND: Repeatedly pairing a tone with a brief burst of vagus nerve stimulation (VNS) results in a reorganization of primary auditory cortex (A1). The plasticity-enhancing and memory-enhancing effects of VNS follow an inverted-U response to stimulation intensity, in which moderate intensity currents yield greater effects than low or high intensity currents. It is not known how other stimulation parameters effect the plasticity-enhancing effects of VNS. OBJECTIVE: We sought to investigate the effect of pulse-width and intensity on VNS efficacy. Here, we used the extent of plasticity induced by VNS-tone pairing to assess VNS efficacy. METHODS: Rats were exposed to a 9 kHz tone paired to VNS with varying current intensities and pulse widths. Cortical plasticity was measured as changes in the percent of area of primary auditory cortex responding to a range of sounds in VNS-treated rats relative to naive rats. RESULTS: We find that a combination of low current intensity (200 MUA) and short pulse duration (100 MUs) is insufficient to drive cortical plasticity. Increasing the pulse duration to 500 MUs results in a reorganization of receptive fields in A1 auditory cortex. The extent of plasticity engaged under these conditions is less than that driven by conditions previously reported to drive robust plasticity (800 MUA with 100 MUs wide pulses). CONCLUSION: These results suggest that the plasticity-enhancing and memory-enhancing effects of VNS follow an inverted-U response of stimulation current that is influenced by pulse width. Furthermore, shorter pulse widths may offer a clinical advantage when determining optimal stimulation current. These findings may facilitate determination of optimal VNS parameters for clinical application. PMID- 29174303 TI - Transcranial Direct Current Stimulation (tDCS) paired with a decision-making task reduces risk-taking in a clinically impulsive sample. AB - BACKGROUND: Impulsivity is a multidimensional personality trait observed across a variety of psychiatric disorders. Transcranial direct current stimulation (tDCS) applied over dorsolateral prefrontal cortex (DLPFC) has shown promise as an intervention to reduce impulsivity. OBJECTIVE: To investigate the effects of tDCS paired with a decision-making task on risk-taking in Veterans with a clinical history of impulsive behavior. METHODS: This was a randomized, single-blind, sham controlled study. Participants performed the Balloon Analogue Risk Task (BART) while concurrently receiving either active or sham tDCS (right anodal/left cathodal over DLPFC) twice a day for five days. To evaluate generalization, the Risk Task was performed before and after the complete course of intervention. To evaluate durability, the BART and Risk Task were administered again at one and two month follow-up sessions. RESULTS: Thirty Veterans participated: 15 received active tDCS and 15 received sham tDCS. For the trained BART task, individual growth curve analysis (IGC) examining individual variation of the growth rates over time showed no significant variations in individual trajectory changes over time (beta = 0.02, p > 0.05). For the untrained Risk Task, IGC showed that the active tDCS group had a significant 46% decrease in risky choice from pre-to post intervention, which persisted through the one and two month follow-up sessions. The sham tDCS group showed no significant change in risky choice from pre-to post intervention. CONCLUSIONS: tDCS over DLPFC paired with a decision-making task effectively reduced risk-taking behavior in a group of Veterans with clinically relevant impulsivity. Results suggest that this approach may be an effective neuroplasticity-based intervention for patients affected by impulsivity. PMID- 29174304 TI - Simultaneous rTMS and psychotherapy in major depressive disorder: Clinical outcomes and predictors from a large naturalistic study. AB - BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) is considered an efficacious non-invasive neuromodulation treatment for major depressive disorder (MDD). However, little is known about the clinical outcome of combined rTMS and psychotherapy (rTMS + PT). Through common neurobiological brain mechanisms, rTMS + PT may exert enhanced antidepressant effects compared to the respective monotherapies. OBJECTIVE: The current naturalistic study aimed to evaluate feasibility and clinical outcome of rTMS + PT in a large group of MDD patients. The second aim was to identify clinical predictors of response and remission. METHODS: A total of 196 patients with MDD were treated with at least 10 sessions of simultaneous rTMS and PT. rTMS was applied over the DLPFC, either 10 Hz left or 1 Hz right. Psychotherapy was based on principles of cognitive behavioral therapy (CBT). Symptoms were measured using the BDI each fifth session until end of treatment and at 6-month follow-up. Comparisons were made between responders and non-responders, as well as between the 10 Hz and 1 Hz protocol. Additionally, baseline variables and early BDI change were evaluated as predictors of response/remission. MAJOR FINDINGS AND CONCLUSIONS: 1) Combining rTMS and PT resulted in a 66% response and a 56% remission rate at the end of treatment with 60% sustained remission at follow-up. Compared to previous findings in RCTs, these rates are relatively high; 2) No differences were found between the 10 Hz and 1 Hz TMS regarding clinical outcome; 3) Clinical baseline variables were not predictive of treatment outcomes; 4) Early symptom improvement (at session 10) was highly predictive of response, and may therefore be used to guide rTMS + PT continuation; 5) Based on the current findings in a large naturalistic study, future studies employing a more standardized method are warranted to draw solid conclusions on the unique effect of rTMS + PT. PMID- 29174305 TI - Perinatal hypothyroidism increases play behaviors in juvenile rats. AB - Thyroid hormones play an instrumental role in the development of the central nervous system. During early development, the fetus is dependent on maternal thyroid hormone production due to the dysfunction of its own thyroid gland. Thus, maternal thyroid dysfunction has been shown to elicit significant abnormalities in neural development, neurochemistry, and behavior in offspring. Previous reports have suggested that human maternal hypothyroidism may increase the chances of having children with autism spectrum disorder and attention deficit/hyperactivity disorder. However, very few studies have evaluated social behaviors in animal models of perinatal hypothyroidism. To evaluate the possibility that hypothyroidism during development influences the expression one of the most commonly observed non-reproductive social behaviors, juvenile play, we used the validated rat model of perinatal hypothyroidism by methimazole administration (MMI; 0.025% in drinking water) from GD12-PD23. Control animals had regular drinking water. During adolescence (PD33-35), we tested subjects for juvenile play behavior by introducing them to a same-sex, unfamiliar (since weaning) littermate for 30min. Play behaviors and other behaviors (sleep, social contact, locomotion) were then scored. MMI-treated subjects played more than twice as much as control animals, and the increase in some behaviors was particularly dramatic in males. Locomotor and other affiliative social behaviors were unaffected. These data suggest that perinatal hypothyroidism may alter the organization of the neural networks regulating play behaviors, but not other social behaviors. Moreover, this implicates perinatal hypothyroidism as a potential etiological factor in the development of neurobehavioral disorders, particularly those characterized by heightened social interactions and impulsivity. PMID- 29174307 TI - Testing the effectiveness of cognitive interventions in alleviating accelerated long term forgetting (ALF). AB - It is well established that when retrieval or other forms of testing follow shortly after the acquisition of new information, long-term memory is improved in healthy subjects (Roediger & Karpicke, 2006). It is not known whether such early interventions would alleviate ALF, a condition in which early retention is normal, but there is a steep decline over longer intervals. A different behavioral intervention (i.e., an interposed recall of a story after a longer delay) was found to prevent subsequent memory loss in a single case with ALF (Jansari, Davis, McGibbon, Firminger, & Kapur, 2010; McGibbon & Jansari, 2013), but this has yet to be replicated. In the present study, we sought to test the effectiveness of early rehearsal as well as a later interposed recall on long term memory. Three men with ALF and 10 matched, healthy males (mean age = 67 yr; mean education = 15 yr) were compared for story recall following 3 early intervention conditions. There were two early rehearsal conditions: Repeated Recall (2 additional recalls were requested in the initial 30 min interval) and Repeated Recall With Discussion (2 additional recalls plus discussion occurred in the initial 30 min interval) as well as a Control condition, in which there was no additional rehearsal in the first 30 min. Memory for 6 stories (2 in each condition) was tested at 0 min, 30 min, 1 day, 1 week and 4 weeks. In addition, to evaluate the possible sustaining effect of an additional retrieval ("booster recall") between 1 wk and 4 wk delays, 1 story from each of the early intervention conditions was recalled at 2 weeks' delay. Consistent with the profile characteristic of ALF, nonparametric statistics revealed no group differences at 0 or 30 min recalls. For Control stories, the ALF group's recall was impaired by 24 h delay. For stories in either of the early rehearsal conditions, the patients showed better retention, performing within normal limits until the 4 week recall. The "booster recall" session at 2 weeks benefitted the patients' retention at 4 weeks, with patients' mean recall remaining within normal limits only for those stories recalled at 2 weeks. These results indicate that behavioral interventions including early rehearsal in the first several min and a booster recall at a much later time point help to prevent ALF. Confirmation of the usefulness of these interventions in other cases and investigating whether these cognitive techniques can be extended to "real world" applications are the logical next steps. PMID- 29174308 TI - Effectiveness of extended release naltrexone to reduce alcohol cravings and use behaviors during treatment and at follow-up. AB - Changes in cravings to drink alcohol and alcohol use behaviors were examined among 337 patients who were administered extended-release naltrexone (XR-NTX) in conjunction with psychosocial treatment in community-based substance use disorder treatment programs. Cravings and use behaviors were assessed at multiple time points (baseline; weeks 1, 2, and 3 after the first dose; monthly after the first four assessments; and at 30- and 60-days after the last dose). A total of 863 doses (M=2.6, SD=1.8) were administered and the majority of patients (65%) took more than one dose. Alcohol craving scores decreased from 19 to 5.7 after the first dose of XR-NTX. Days of primary alcohol use at admission (M=10.5, SD=10.1) were reduced at discharge (M=to 1.2, SD=4.6). At the first follow-up, 79.8% reported no alcohol use and 77.8% reported no alcohol use at the second follow up. The expected side effects were reported but the medication was well tolerated and there was no relationship between side effects and subsequent dose. Unexamined or unaccounted for variables (e.g., motivation, external pressures to remain in treatment) are "real world" consequences that may have impacted the outcome of this study. Results indicated that use of the antagonist medication XR NTX may be related to significant decreases in alcohol craving and use while a patient is in treatment, as well as at 30- and 60-days after the final dose. PMID- 29174306 TI - Sex and gender differences in substance use disorders. AB - The gender gap in substance use disorders (SUDs), characterized by greater prevalence in men, is narrowing, highlighting the importance of understanding sex and gender differences in SUD etiology and maintenance. In this critical review, we provide an overview of sex/gender differences in the biology, epidemiology and treatment of SUDs. Biological sex differences are evident across an array of systems, including brain structure and function, endocrine function, and metabolic function. Gender (i.e., environmentally and socioculturally defined roles for men and women) also contributes to the initiation and course of substance use and SUDs. Adverse medical, psychiatric, and functional consequences associated with SUDs are often more severe in women. However, men and women do not substantively differ with respect to SUD treatment outcomes. Although several trends are beginning to emerge in the literature, findings on sex and gender differences in SUDs are complicated by the interacting contributions of biological and environmental factors. Future research is needed to further elucidate sex and gender differences, especially focusing on hormonal factors in SUD course and treatment outcomes; research translating findings between animal and human models; and gender differences in understudied populations, such as those with co-occurring psychiatric disorders and gender-specific populations, such as pregnant women. PMID- 29174309 TI - Lung cancer's real adjuvant EGFR targeted therapy questions. PMID- 29174311 TI - Mdivi-1 alleviates blood-brain barrier disruption and cell death in experimental traumatic brain injury by mitigating autophagy dysfunction and mitophagy activation. AB - Dynamin-related protein 1 (Drp1) is a key regulator of mitochondrial fission. Our previous studies proved that the inhibition of Drp1 may help attenuate traumatic brain injury (TBI)-induced functional outcome and cell death through maintaining normal mitochondrial morphology and inhibiting activation of apoptosis. However, the molecular mechanisms of Drp1 after TBI remain poorly understood. In this study, we investigated the role of mitochondrial division inhibitor 1 (Mdivi-1), a small molecule inhibitor of Drp1, in underlying mechanisms of general autophagy and mitochondria autophagy (mitophagy) after experimental TBI. In vivo, we found that autophagosomes accumulated in cortical neurons at 24h after TBI, owing to the enhanced autophagy indicated by the accumulation of LC3 and the decrease of p62; but Mdivi-1 reversed the enhancement. Mdivi-1 also alleviated the number of LC3 puncta and TUNEL-positive structures in cells, indicating that autophagy maybe involved in Mdivi-1's anti-apoptosis effects. Then, the expression level of mitochondrial dynamics related and mitophagy related proteins was assessed using the isolated mitochondria. The results showed that TBI-induced mitochondrial fission (represented by Drp1), mtDNA concentration down-regulation and PTEN induced putative kinase 1 (PINK1)-Parkin mediated mitophagy activation were all inhibited by Mdivi-1. In addition, TBI-induced blood-brain barrier (BBB) disruption and matrix metalloproteinases (MMP)-9 expression up-regulation were inhibited following Mdivi-1 treatment. In vitro, Mdivi-1 significantly alleviated the scratch injury-induced cell death, loss of mitochondrial membrane potential, reactive oxygen species (ROS) production and ATP reduction in primary cortical neurons (PCNs). Additionally, the lysosome inhibitor chloroquine (CQ) abrogated the Mdivi-1-induced decrease in autophagosomes accumulation and cell death at 24h both in the basal state and under the conditions of scratch cell injury. Together, these data demonstrate that Mdivi-1 mitigates TBI-induced BBB disruption and cell death at least in part by a mechanism involving inhibiting autophagy dysfunction and mitophagy activation. PMID- 29174310 TI - Gefitinib versus vinorelbine plus cisplatin as adjuvant treatment for stage II IIIA (N1-N2) EGFR-mutant NSCLC (ADJUVANT/CTONG1104): a randomised, open-label, phase 3 study. AB - BACKGROUND: Cisplatin-based adjuvant chemotherapy is the standard of care for patients with resected stage II-IIIA non-small-cell lung cancer (NSCLC). RADIANT and SELECT trial data suggest patients with EGFR-mutant stage IB-IIIA resected NSCLC could benefit from adjuvant EGFR tyrosine kinase inhibitor treatment. We aimed to compare the efficacy of adjuvant gefitinib versus vinorelbine plus cisplatin in patients with completely resected EGFR-mutant stage II-IIIA (N1-N2) NSCLC. METHODS: We did a randomised, open-label, phase 3 trial at 27 centres in China. We enrolled patients aged 18-75 years with completely resected (R0), stage II-IIIA (N1-N2), EGFR-mutant (exon 19 deletion or exon 21 Leu858Arg) NSCLC. Patients were stratified by N stage and EGFR mutation status and randomised (1:1) by Pocock and Simon minimisation with a random element to either gefitinib (250 mg once daily) for 24 months or intravenous vinorelbine (25 mg/m2 on days 1 and 8) plus intravenous cisplatin (75 mg/m2 on day 1) every 3 weeks for four cycles. The primary endpoint was disease-free survival in the intention-to-treat population, which comprised all randomised patients; the safety population included all randomised patients who received at least one dose of study medication. Enrolment to the study is closed but survival follow-up is ongoing. The study is registered with ClinicalTrials.gov, number NCT01405079. FINDINGS: Between Sept 19, 2011, and April 24, 2014, 483 patients were screened and 222 patients were randomised, 111 to gefitinib and 111 to vinorelbine plus cisplatin. Median follow-up was 36.5 months (IQR 23.8-44.8). Median disease-free survival was significantly longer with gefitinib (28.7 months [95% CI 24.9-32.5]) than with vinorelbine plus cisplatin (18.0 months [13.6-22.3]; hazard ratio [HR] 0.60, 95% CI 0.42-0.87; p=0.0054). In the safety population, the most commonly reported grade 3 or worse adverse events in the gefitinib group (n=106) were raised alanine aminotransferase and asparate aminotransferase (two [2%] patients with each event vs none with vinorelbine plus cisplatin). In the vinorelbine plus cisplatin group (n=87), the most frequently reported grade 3 or worse adverse events were neutropenia (30 [34%] patients vs none with gefitinib), leucopenia (14 [16%] vs none), and vomiting (eight [9%] vs none). Serious adverse events were reported for seven (7%) patients who received gefitinib and 20 (23%) patients who received vinorelbine plus cisplatin. No interstitial lung disease was noted with gefitinib. No deaths were treatment related. INTERPRETATION: Adjuvant gefitinib led to significantly longer disease-free survival compared with that for vinorelbine plus cisplatin in patients with completely resected stage II-IIIA (N1-N2) EGFR-mutant NSCLC. Based on the superior disease-free survival, reduced toxicity, and improved quality of life, adjuvant gefitinib could be a potential treatment option compared with adjuvant chemotherapy in these patients. However, the duration of benefit with gefitinib after 24 months might be limited and overall survival data are not yet mature.

PMID- 29174313 TI - The effect of cool water pack preparation on vaccine vial temperatures in refrigerators. AB - Cool water packs are a useful alternative to ice packs for preventing unintentional freezing of vaccines during outreach in some situations. Current guidelines recommend the use of a separate refrigerator for cooling water packs from ambient temperatures to prevent possible heat degradation of adjacent vaccine vials. To investigate whether this additional equipment is necessary, we measured the temperatures that vaccine vials were exposed to when warm water packs were placed next to vials in a refrigerator. We then calculated the effect of repeated vial exposure to those temperatures on vaccine vial monitor status to estimate the impact to the vaccine. Vials were tested in a variety of configurations, varying the number and locations of vials and water packs in the refrigerator. The calculated average percentage life lost during a month of repeated warming ranged from 20.0% to 30.3% for a category 2 (least stable) vaccine vial monitor and from 3.8% to 6.0% for a category 7 (moderate stability) vaccine vial monitor, compared to 17.0% for category 2 vaccine vial monitors and 3.1% for category 7 vaccine vial monitors at a constant 5 degrees C. The number of vials, number of water packs, and locations of each impacted vial warming and therefore percentage life lost, but the vaccine vial monitor category had a higher impact on the average percentage life lost than any of the other parameters. The results suggest that damage to vaccines from repeated warming over the course of a month is not certain and that cooling water packs in a refrigerator where vaccines are being stored may be a useful practice if safe procedures are established. PMID- 29174312 TI - Association of Corynebacterium pseudotuberculosis recombinant proteins rCP09720 or rCP01850 with rPLD as immunogens in caseous lymphadenitis immunoprophylaxis. AB - Caseous lymphadenitis (CLA) is a chronic disease responsible for significant economic losses in sheep and goat breeding worldwide. The treatment for this disease is not effective, and an intense vaccination schedule would be the best control strategy. In this study, we evaluated the associations of rCP09720 or rCP01850 proteins from Corynebacterium pseudotuberculosis with recombinant exotoxin phospholipase D (rPLD) as subunit vaccines in mice. Four experimental groups (10 animals each) were immunized with a sterile 0.9% saline solution (G1), rPLD (G2), rPLD + rCP09720 (G3), and rPLD + rCP01850 (G4). The mice received two doses of each vaccine at a 21-day interval and were challenged 21 days after the last immunization. The animals were evaluated daily for 40 days after the challenge, and mortality rate was recorded. The total IgG production level increased significantly in the experimental groups on day 42 after the first vaccination. Similarly, higher levels of specific IgG2a were observed in experimental groups G2, G3, and G4 compared to the IgG1 levels on day 42. G4 showed a significant (p < .05) humoral response against both antigens of the antigenic formulations. The cellular immune response induced by immunization was characterized by a significant (p < .05) production of interferon-gamma compared to that in the control, while the concentrations of interleukin (IL)-4 and IL-12 were not significant in any group. A significant increase of tumor necrosis factor was observed only in G4. The survival rates after the challenge were 30% (rPLD), 40% (rPLD + rCP09720), and 50% (rPLD + rCP01850). Thus, the association of rCP01850 with rPLD resulted in the best protection against the challenge with C. pseudotuberculosis and induced a more intense type 1 T-helper cell immune response. PMID- 29174314 TI - Development of a broadly protective modified-live virus vaccine candidate against porcine reproductive and respiratory syndrome virus. AB - Modified-live virus (MLV) vaccines are widely used to protect pigs against porcine reproductive and respiratory syndrome virus (PRRSV). However, current MLV vaccines do not confer adequate levels of heterologous protection, presumably due to the substantial genetic diversity of PRRSV isolates circulating in the field. To overcome this genetic variation challenge, we recently generated a synthetic PRRSV strain containing a consensus genomic sequence of PRRSV-2. We demonstrated that our synthetic PRRSV strain confers unprecedented levels of heterologous protection. However, the synthetic PRRSV strain at passage 1 (hereafter designated CON-P1) is highly virulent and therefore, is not suitable to be used as a vaccine in pigs. In the present study, we attenuated CON-P1 by continuously passaging the virus in MARC-145 cells, a non-natural host cell line. Using a young pig model, we demonstrated that the synthetic virus at passages 90 and 122 (designated as CON-P90 and CON-P122, respectively) were fully attenuated, as evidenced by the significantly reduced viral loads in serum and tissues and the absence of lung lesion in the infected pigs. Most importantly, CON-P90 confers similar levels of heterologous protection as its parental strain CON-P1. Taken together, the results indicate that CON-P90 is an excellent candidate for the formulation of next generation of PRRSV MLV vaccines with improved levels of heterologous protection. PMID- 29174315 TI - Workshop report: Nucleic acid delivery devices for HIV vaccines: Workshop proceedings, National Institute of Allergy and Infectious Diseases, Bethesda, Maryland, USA, May 21, 2015. AB - On May 21st, 2015, the U.S. National Institute of Allergy and Infectious Diseases (NIAID) convened a workshop on delivery devices for nucleic acid (NA) as vaccines in order to review the landscape of past and future technologies for administering NA (e.g., DNA, RNA, etc.) as antigen into target tissues of animal models and humans. Its focus was on current and future applications for preventing and treating human immunodeficiency virus (HIV) infection and acquired immune deficiency syndrome (AIDS) disease, among other infectious-disease priorities. Meeting participants presented the results and experience of representative clinical trials of NA vaccines using a variety of alternative delivery devices, as well as a broader group of methods studied in animal models and at bench top, to improve upon the performance and/or avoid the drawbacks of conventional needle-syringe (N-S) delivery. The subjects described and discussed included (1) delivery targeted into oral, cutaneous/intradermal, nasal, upper and lower respiratory, and intramuscular tissues; (2) devices and techniques for jet injection, solid, hollow, and dissolving microneedles, patches for topical passive diffusion or iontophoresis, electroporation, thermal microporation, nasal sprayers, aerosol upper-respiratory and pulmonary inhalation, stratum-corneum ablation by ultrasound, chemicals, and mechanical abrasion, and kinetic/ballistic delivery; (3) antigens, adjuvants, and carriers such as DNA, messenger RNA, synthesized plasmids, chemokines, wet and dry aerosols, and pollen-grain and microparticle vectors; and (4) the clinical experience and humoral, cellular, and cytokine immune responses observed for many of these target tissues, technologies, constructs, and carriers. This report summarizes the presentations and discussions from the workshop (https://web.archive.org/web/20160228112310/https://www.blsmeetings.net/NucleicAc dDeliveryDevices/), which was webcast live in its entirety and archived online (http://videocast.nih.gov/summary.asp?live=16059). PMID- 29174316 TI - A phase II randomized study to determine the safety and immunogenicity of the novel PIKA rabies vaccine containing the PIKA adjuvant using an accelerated regimen. AB - BACKGROUND: Human Rabies infection continues to be potentially fatal despite the availability of post-exposure prophylaxis with rabies vaccine. The PIKA Rabies vaccine adjuvant is a TLR3 agonist and has been shown to be safe and immunogenic in clinical phase I studies. METHODS: We conducted a phase II, open label, randomized study in healthy adults to assess the safety and immunogenicity of the PIKA rabies vaccine under an accelerated regimen. 126 subjects were randomized into two groups: control vaccine classic regimen ("control-classic") and PIKA vaccine accelerated regimen ("PIKA-accelerated"). Subjects were followed up for safety and rabies virus neutralizing antibodies (RVNA). RESULTS: Both the control and PIKA vaccines were generally well tolerated. 57.6% of subjects in the PIKA vaccine group, compared with 43.8% of subjects in the control-classic group, achieved the target RVNA titer of >=0.5 IU/mL by Day 7. All subjects achieved the target RVNA titer by Day 14. The RVNA geometric mean titer at Day 7 was 0.60 IU/ml in the PIKA vaccine group and 0.39 IU/ml in the control-classic group. At Day 14, the RVNA geometric mean titer was 18.25 IU/ml in the PIKA-accelerated group and 19.24 IU/ml in the control-classic group. The median time taken to reach the target RVNA titer level of >=0.5 IU/mL was 7.0 days (95% CI: 7.0-42.0 days) in the PIKA-accelerated group and 14.0 days (95% CI: 7.0-42.0 days) in the control-classic group. CONCLUSION: The accelerated regimen using the investigational PIKA Rabies vaccine was well-tolerated and demonstrated non inferior immunogenicity compared to the classic regimen using the commercially available vaccine in healthy adults. Clinical trial registry: The study was registered with clinicaltrials.gov (NCT02956421). PMID- 29174317 TI - Status and progress of hepatitis B control through vaccination in the South-East Asia Region, 1992-2015. AB - In 2016, the Immunization Technical Advisory Group of the South-East Asia Region (SEAR) endorsed a regional goal to achieve <=1% prevalence of hepatitis B surface antigen (HBsAg) among 5-year-old children by 2020. Chronic hepatitis B virus (HBV) infection is largely preventable with a birth dose of hepatitis B vaccine (HepB-BD) followed by two to three additional doses. We reviewed the progress towards hepatitis B control through vaccination in SEAR during 1992-2015. We summarized hepatitis B vaccination data and reviewed the literature to determine the prevalence of chronic HBV infection pre- and post-vaccine introduction. We used a mathematical model to determine post-vaccine prevalence of HBsAg among 5 year olds in countries lacking national serosurvey data and estimated the impact of vaccination on disease burden. Regional coverage with three doses of hepatitis B vaccine (HepB3) increased from 56% in 2011 to 87% in 2015. By 2016, 7 of 11 countries had introduced universal HepB-BD. Regional HepB-BD coverage increased from 9% in 2011 to 34% in 2015. In 2015, estimated HBsAg among 5 year olds was 1.1% with variability among countries. Myanmar (3.8%), Timor-Leste (2.7%), Indonesia (1.8%), and India (1%) had the highest prevalence of HBsAg. During 1992 2015, vaccination prevented approximately 16 million chronic HBV infections and 2.6 million related deaths. In 2015, around 197,640 perinatal HBV infections occurred in SEAR with majority occurring in India (62%), Bangladesh (24%), and Myanmar (8%). Myanmar had the highest rate of perinatal chronic HBV infections at 16 per 1000 live births. Despite significant progress in the control of HBV, SEAR needs to secure political commitment for elimination and consider additional strategies, such as promoting health facility births, universal birth dose administration, developing strong coordination between health sectors, and using alternative vaccine delivery methods, to improve HepB-BD coverage and subsequently achieve HBV control and elimination. PMID- 29174318 TI - Factors influencing on influenza vaccination and its trends of coverage in patients with diabetes in Korea: A population-based cross-sectional study. AB - BACKGROUND: Influenza infection is a contagious disease and annual influenza vaccination is recommended to the patients with chronic diseases. Although diabetes is an indication for influenza vaccination, the global rate of influenza vaccination is insufficient. Therefore, our study aimed to elucidate influenza vaccination statuses among patients with diabetes and the related factors in Korea. METHODS: A total of 32,268 subjects (4,540 with and 27,728 without diabetes) from the Korea National Health and Nutrition Examination Survey III-VI (2005-2015) were included. Socioeconomic factors and health-related factors were analyses for the relation of influenza vaccination by Student's t-test, the chi squared test and a multivariate logistic regression analysis. RESULTS: The influenza vaccination coverage rates were 50.0% in the diabetes mellitus (DM) group and 38.2% in the non-DM group. The trends in influenza vaccination rates during KNHANES III-VI were not significant in each group (P trend = 0.24 in the DM group, 0.30 in the non-DM group). Socioeconomic (older age, female sex, higher family income, and medical aid insurance) and health-related factors (lack of risky alcohol consumption, obesity, and recent health check-ups) were associated with influenza vaccination among patients with DM. CONCLUSIONS: The rate of influenza vaccination among patients with diabetes is insufficient in Korea. More efforts are needed to increase the influenza vaccination rates among vulnerable at-risk populations. PMID- 29174319 TI - Different Dietary Patterns and New-Onset Diabetes Mellitus After Kidney Transplantation: A Cross-Sectional Study. AB - OBJECTIVE: To verify the association of dietary patterns and dietary components with new-onset diabetes mellitus after transplantation (NODAT). DESIGN: Cross sectional study. SUBJECTS: Adult kidney transplant recipients, without history of diabetes before transplantation, who received a kidney transplant and were followed up for at least 1 year. One hundred and sixteen subjects recruited between January 2013 and August 2014. Diagnosis of NODAT was established according to the American Diabetes Association criteria for type 2 diabetes. METHODS: Demographic, clinical, and anthropometric data were collected. Dietary intake was assessed by food frequency questionnaire, administered by a registered dietitian. Dietary patterns were identified by cluster analysis. Chi-square test was used to verify the association between dietary patterns and NODAT. Total energy, fiber, and cholesterol intake were calculated. Consumption of macronutrients, carbohydrates, proteins, and fats (total fats and saturated, monounsaturated, polyunsaturated and trans fatty acids), were expressed in percentage of total energy intake. RESULTS: Twenty-eight patients developed NODAT in the follow-up period. They presented higher body mass index and body fat percentage, as well as higher levels of triglycerides and urinary protein/creatinine ratio than the non-NODAT group. Two dietary patterns, I and II, were identified. Pattern II was characterized by higher intake of total, saturated, monounsaturated, and trans fats than pattern I. No association between the dietary patterns and NODAT was identified (P = .905), and there was no difference in the distribution of macronutrients, dietary fiber, and dietary cholesterol between the groups with and without NODAT. CONCLUSION: Posttransplant dietary patterns were not different between patients with and without NODAT. Further larger and prospective studies are needed to evaluate a possible relationship between dietary components and NODAT incidence in kidney transplant recipients.

AB - CAR T-cells are autologous or allogeneic human lymphocytes that are genetically engineered to express a chimeric antigen receptor targeting an antigen expressed on tumor cells such as CD19. CAR T-cells represent a new class of medicinal products, and belong to the broad category of Advanced Therapy Medicinal Products (ATMPs), as defined by EC Regulation 2007-1394. Specifically, they are categorized as gene therapy medicinal products. Although CAR T-cells are cellular therapies, the organization for manufacturing and delivery is far different from the one used to deliver hematopoietic cell grafts, for different reasons including their classification as medicinal products. Currently available clinical observations were mostly produced in the context of trials conducted either in the USA or in China. They demonstrate remarkable efficacy for patients presenting advanced or poor-prognosis hematological malignancies, however with severe side effects in a significant proportion of patients. Toxicities can and must be anticipated and dealt with in the context of a full coordination between the clinical cell therapy ward in charge of the patient, and the neighboring intensive care unit. The present workshop aimed at identifying prerequisites to be met in order for French hospitals to get efficiently organized and fulfill sponsors' expectations before initiation of clinical trials designed to investigate CAR T-cells.

PMID- 29174322 TI - Comparison of Patient Survival Between Hemodialysis and Peritoneal Dialysis Among Patients Eligible for Both Modalities. AB - BACKGROUND: Although peritoneal dialysis (PD) costs less to the health care system compared to in-center hemodialysis (HD), it is an underused therapy. Neither modality has been consistently shown to confer a clear benefit to patient survival. A key limitation of prior research is that study patients were not restricted to those eligible for both therapies. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: All adult patients developing end-stage renal disease from January 2004 to December 2013 at any of 7 regional dialysis centers in Ontario, Canada, who had received at least 1 outpatient dialysis treatment and had completed a multidisciplinary modality assessment. PREDICTOR: HD or PD. OUTCOMES: Mortality from any cause. RESULTS: Among all incident patients with end-stage renal disease (1,579 HD and 453 PD), PD was associated with lower risk for death among patients younger than 65 years. However, after excluding approximately one-third of all incident patients deemed to be ineligible for PD, the modalities were associated with similar survival regardless of age. This finding was also observed in analyses that were restricted to patients initiating dialysis therapy electively as outpatients. The impact of modality on survival did not vary over time. LIMITATIONS: The determination of PD eligibility was based on the judgment of the multidisciplinary team at each dialysis center. CONCLUSIONS: HD and PD are associated with similar mortality among incident dialysis patients who are eligible for both modalities. The effect of modality on survival does not appear to change over time. Future comparisons of dialysis modality should be restricted to individuals who are deemed eligible for both modalities to reflect the outcomes of patients who have the opportunity to choose between HD and PD in clinical practice. PMID- 29174324 TI - When less is more: how many doses of PCV are enough? PMID- 29174323 TI - Pneumococcal conjugate vaccine 13 delivered as one primary and one booster dose (1 + 1) compared with two primary doses and a booster (2 + 1) in UK infants: a multicentre, parallel group randomised controlled trial. AB - BACKGROUND: Infants in the UK were first offered a pneumococcal conjugate vaccine (PCV7) in 2006, given at 2 and 4 months of age and a booster dose at 13 months (2 + 1 schedule). A 13-valent vaccine (PCV13) replaced PCV7 in 2010. We aimed to compare the post-booster antibody response in UK infants given a reduced priming schedule of PCV13 (ie, a 1 + 1 schedule) versus the current 2 + 1 schedule and to assess the potential effect on population protection. METHODS: In this multicentre, parallel group, randomised controlled trial, we recuited infants due to receive their primary immunisations aged up to 13 weeks on first vaccinations by information booklets mailed out via the NHS Child Health Information Service and the UK National Health Application and Infrastructure Services. Eligible infants were randomly assigned (1:1) to receive PCV13 at 2, 4, and 12 months (2 + 1 schedule) or 3 and 12 months of age (1 + 1 schedule) delivered with other routine vaccinations. Randomisation was done by computer-generated permuted block randomisation, with a block size of six. Participants and clinical trial staff were not masked to treatment allocation. The primary endpoint was serotype specific immunoglobulin G concentrations values (geometric mean concentrations [GMC] in MUg/mL) measured in blood samples collected at 13 months of age. Analysis was by modified intention to treat with all individuals included by randomised group if they had a laboratory result. This trial is registered on the EudraCT clinical trial database, number 2015-000817-32, and ClinicalTrials.gov, number NCT02482636. FINDINGS: Between September, 2015, and June, 2016, 376 infants were assessed for eligibility. 81 infants were excluded for not meeting the inclusion criteria (n=50) or for other reasons (n=31). 213 eligible infants were enrolled and randomly allocated to group 1 (n=106; 2 + 1 schedule) or to group 2 (n=107; 1 + 1 schedule). In group 1, 91 serum samples were available for analysis 1 month after booster immunisation versus 86 in group 2. At month 13, post-booster, GMCs were equivalent between schedules for serotypes 3 (0.61 MUg/mL in group 1 vs 0.62 MUg/mL in group 2), 5 (1.74 MUg/mL vs 2.11 MUg/mL), 7F (3.98 MUg/mL vs 3.36 MUg/mL), 9V (2.34 MUg/mL vs 2.50 MUg/mL), and 19A (8.38 MUg/mL vs 8.83 MUg/mL). Infants given the 1 + 1 schedule had significantly greater immunogenicity post-booster than those given the 2 + 1 schedule for serotypes 1 (8.92 MUg/mL vs 3.07 MUg/mL), 4 (3.43 MUg/mL vs 2.55 MUg/mL), 14 (16.9 MUg/mL vs 10.49 MUg/mL), and 19F (14.76 MUg/mL vs 11.12 MUg/mL; adjusted p value range <0.001 to 0.047). The 2 + 1 schedule was superior for serotypes 6A, 6B, 18C and 23F (adjusted p value range <0.0001 to 0.017). In a predefined numerical subset of all of the infants recruited to the study (n=40 [20%]), functional serotype specific antibody was similar between schedules. 26 serious adverse events were recorded in 21 (10%) infants across the study period; 18 (n=13) were in the 2 + 1 group and eight (n=8) in the 1 + 1 group. Only one serious adverse event, a high temperature and refusal to feed after the first vaccination visit in a child on the 2+1 schedule was considered related to vaccine. INTERPRETATION: Our findings show that for nine of the 13 serotypes in PCV13, post-booster responses in infants primed with a single dose are equivalent or superior to those seen following the standard UK 2 + 1 schedule. Introducing a 1 + 1 schedule in countries with a mature PCV programme and established herd immunity is likely to maintain population control of vaccine-type pneumococcal disease.

PMID- 29174327 TI - Cardiac arrest associated with aortic valve regurgitation. AB - Blunt chest trauma can cause not only damage to the thoracic cage, but can also injure intracardiac structures including the papillary muscles, chordae tendineae, and valve leaflets. Aortic valve (AV) injury secondary to blunt chest trauma is a rare occurrence. Clinically, AV injury may be missed during the initial post-trauma assessment due to the lack of suspicion of cardiac involvement. Thus, the diagnosis of AV injury is often delayed or missed for a time interval of days to months. As a consequence, the traumatic AV regurgitation can rapidly or progressively lead to congestive heart failure unless surgically corrected. Therefore, emergency physicians should be aware of the possibility of intracardiac structure injury, such as valvular injuries, after blunt chest trauma. Guidelines for the appropriate use of bedside cardiac ultrasound (BCU) recommend BCU should be performed in all patients with new murmurs for clinically significant valvular lesions that could potentially change management. We described the case of a 73-year-old female patient with AV injury after blunt trauma. She experienced cardiac arrest (CA) secondary to a moderate-to-severe traumatic AR, which was successfully treated with emergency AV replacement. We discuss how to diagnose and manage a CA patient, aided by BCU, with ventricular failure associated with persistent AV regurgitation. To the best of our knowledge, this is the first case report on CA associated with isolated rupture of bicuspid AV rupture and AV regurgitation secondary to blunt chest trauma because of the lack of early suspicion of AV injury. PMID- 29174328 TI - Variation in hospital admission rates between a tertiary care and two freestanding emergency departments. AB - BACKGROUND: Recently, freestanding emergency departments (FSEDs) have grown significantly in number. Critics have expressed concern that FSEDs may increase healthcare costs. OBJECTIVE: We determined whether admission rates for identical diagnoses varied among the same group of physicians according to clinical setting. METHODS: This was a retrospective comparison of adult admission rates (n=3230) for chest pain, chronic obstructive pulmonary disease (COPD), asthma, and congestive heart failure (CHF) between a hospital-based ED (HBED) and two FSEDs throughout 2015. Frequency distribution and proportions were reported for categorical variables stratified by facility type. For categories with cell frequency less or equal to 5, Fisher's Exact test was used to calculate a P value. Chi square tests were used to assess difference in proportions of potential predictor variables between the HBED and FSEDs. For continuous variables, the mean was reported and Student's t-test assessed the difference in means between HBED and FSED patients. Multivariate logistic regression analyses were performed to estimate the unadjusted and adjusted prevalence odds ratio with 95% confidence interval (CI) for patient disposition outcomes associated with type of ED facility visited. RESULTS: Of 3230 patients, 53% used the HBED and 47% used the FSED. Patients visiting the HBED and FSED varied significantly in gender, acuity levels, diagnosis, and number of visits. Age was not significantly different between facilities. Multivariable adjusted estimated prevalence odds ratio for patients admitted were 1.2 [95%CI: 1.0-1.4] in the HBED facility compared to patients using FSEDs. CONCLUSION: In our healthcare system, FSEDs showed a trend towards a 20% lower admission rate for chest pain, COPD, asthma and CHF. PMID- 29174329 TI - Initial inferior vena cava diameter predicts massive transfusion requirements in blunt trauma patients: A retrospective cohort study. AB - OBJECTIVES: The inferior vena cava (IVC) diameter is associated with shock and increased mortality in trauma patients. However, there are no reports examining the association between the IVC diameter and massive transfusion (MT) requirements in trauma patients. The aim of this study was to evaluate the association between IVC diameter and MT requirements in patients with blunt trauma. METHODS: We retrospectively reviewed all patients who were consecutively hospitalized with blunt trauma (Injury Severity Score [ISS] >=16) between from November 1, 2011 to March 30, 2016. Univariate and multivariate analyzes were performed to identify the independent predictors of MT (defined as >10units of red cell concentrate transfusions within 24h of admission). Receiver operating characteristic curve and the area under the curve (AUC) were estimated. RESULTS: Of the 222 patients included in this study, MT occurred in 22.5% patients. On multiple regression analysis, IVC diameter [Odds ratio (OR), 0.88; 95% confidence interval (CI), 0.80-0.96; p<0.01], fibrin degradation product (FDP; OR, 1.01; 95% CI, 1.00-1.01; p<0.01), and fibrinogen level (OR, 0.99; 95% CI, 0.98-1.00; p<0.01) were strong predictors of MT. IVC diameter demonstrated moderate accuracy (AUC, 0.74; cutoff level, 13.0mm; sensitivity, 67%; specificity, 73%). Combined cutoff levels of FDP <80.5MUg/ml, fibrinogen >=165mg/dl, and IVC diameter >=13mm could also determine how unnecessary a MT was with 100% accuracy. CONCLUSIONS: Initial IVC diameter is a predictor of MT in blunt trauma patients. PMID- 29174330 TI - Association between commercial vehicle driver at-fault crashes involving sleepiness/fatigue and proximity to rest areas and truck stops. AB - INTRODUCTION: There is ongoing concern at the national level about the availability of adequate commercial vehicle rest areas and truck stops for commercial vehicle drivers to rest or to wait for a delivery window. METHODS: A retrospective case-control study was conducted to determine the association between the occurrence of sleepiness/fatigue-related (cases) vs. all other human factor-related commercial vehicle driver at-fault crashes (controls) and proximity to rest areas, weigh stations with rest havens, and truck stops. RESULTS: Commercial vehicle driver at-fault crashes involving sleepiness/fatigue were more likely to occur on roadways where the nearest rest areas/weigh stations with rest havens/truck stops were located 20 miles or more from the commercial vehicle crash site (Odds Ratio [OR]=2.32; Confidence Interval [CI] 1.615, 3.335] for 20-39.9 miles vs. <20 miles; and OR=6.788 [CI 2.112, 21.812] for 40+ miles) compared to commercial vehicle at-fault driver crashes with human factors other than sleepiness/fatigue cited in crash reports. Commercial vehicle driver at fault crashes involving sleepiness/fatigue also were more likely to occur on parkways compared to interstates (adjusted OR=3.747 [CI 2.83, 4.95]), during nighttime hours (adjusted OR=6.199 [CI 4.733, 8.119]), and on dry pavement (adjusted OR 1.909, [CI 1.373, 2.655]). CONCLUSIONS: The use of statewide crash data analysis coupled with ArcGIS mapping capabilities provided the opportunity to both statistically determine and to visualize the association between rest area/weigh station with rest haven/truck stop distance and the occurrence of commercial vehicle driver at-fault crashes involving sleepiness/fatigue. Implementation and evaluation of commercial vehicle employer policies and interventions such as the use of commercial vehicle driver fatigue alert systems may help to reduce fatigue and sleepiness in commercial vehicle drivers. These results can be used by state and local highway transportation officials to inform and increase truck parking availability, especially on parkways. PMID- 29174331 TI - Constitutively Active SMAD2/3 Are Broad-Scope Potentiators of Transcription Factor-Mediated Cellular Reprogramming. AB - Reprogramming of cellular identity using exogenous expression of transcription factors (TFs) is a powerful and exciting tool for tissue engineering, disease modeling, and regenerative medicine. However, generation of desired cell types using this approach is often plagued by inefficiency, slow conversion, and an inability to produce mature functional cells. Here, we show that expression of constitutively active SMAD2/3 significantly improves the efficiency of induced pluripotent stem cell (iPSC) generation by the Yamanaka factors. Mechanistically, SMAD3 interacts with reprogramming factors and co-activators and co-occupies OCT4 target loci during reprogramming. Unexpectedly, active SMAD2/3 also markedly enhances three other TF-mediated direct reprogramming conversions, from B cells to macrophages, myoblasts to adipocytes, and human fibroblasts to neurons, highlighting broad and general roles for SMAD2/3 as cell-reprogramming potentiators. Our results suggest that co-expression of active SMAD2/3 could enhance multiple types of TF-based cell identity conversion and therefore be a powerful tool for cellular engineering. PMID- 29174332 TI - Injury Induces Endogenous Reprogramming and Dedifferentiation of Neuronal Progenitors to Multipotency. AB - Adult neurogenesis in the olfactory epithelium is often depicted as a unidirectional pathway during homeostasis and repair. We challenge the unidirectionality of this model by showing that epithelial injury unlocks the potential for Ascl1+ progenitors and Neurog1+ specified neuronal precursors to dedifferentiate into multipotent stem/progenitor cells that contribute significantly to tissue regeneration in the murine olfactory epithelium (OE). We characterize these dedifferentiating cells using several lineage-tracing strains and single-cell mRNA-seq, and we show that Sox2 is required for initiating dedifferentiation and that inhibition of Ezh2 promotes multipotent progenitor expansion. These results suggest that the apparent hierarchy of neuronal differentiation is not irreversible and that lineage commitment can be overridden following severe tissue injury. We elucidate a previously unappreciated pathway for endogenous tissue repair by a highly regenerative neuroepithelium and introduce a system to study the mechanisms underlying plasticity in the OE that can be adapted for other tissues. PMID- 29174334 TI - Is there a common vulnerability in cannabis phenomenology and schizotypy? The role of the N170 ERP. AB - Cannabis use is a known risk factor for the development of psychosis, although the precise nature of this relationship is unclear. The phenomenological experiences associated with cannabis use vary dramatically, and for some resemble certain features of psychosis. We hypothesized that individuals who report particularly unusual experiences associated with cannabis use would demonstrate similar electrophysiological patterns to those who score high on schizotypal personality traits. The Cannabis Experiences Questionnaire (CEQ) and the Schizotypal Personality Questionnaire (SPQ) were used to measure these experiences and traits. A sample of 97 individuals were placed into one of three experimental or two control groups based on their questionnaire scores. These were the "High CEQ", "High SPQ", "High on Both", "Average Users" and "Control" (non-using) groups. Participants completed a visual face perception task. Electroencephalography was used to measure the neural response to the stimuli. The N170 event-related potential (ERP) was used to measure perceptual encoding of the stimulus. The experimental groups elicited significantly reduced N170 ERPs compared to the Control group. The Average User group did not significantly differ from the Control group, and approached significance with the High SPQ group. None of the high scoring groups significantly differed in N170 ERP response from each other. Replicating past research, the CEQ and SPQ scales moderately correlated with each other. The attenuated N170 ERP demonstrated by the high scoring experimental groups may reflect a manifestation of an underlying shared vulnerability. PMID- 29174333 TI - Injury Activates Transient Olfactory Stem Cell States with Diverse Lineage Capacities. AB - Tissue homeostasis and regeneration are mediated by programs of adult stem cell renewal and differentiation. However, the mechanisms that regulate stem cell fates under such widely varying conditions are not fully understood. Using single cell techniques, we assessed the transcriptional changes associated with stem cell self-renewal and differentiation and followed the maturation of stem cell derived clones using sparse lineage tracing in the regenerating mouse olfactory epithelium. Following injury, quiescent olfactory stem cells rapidly shift to activated, transient states unique to regeneration and tailored to meet the demands of injury-induced repair, including barrier formation and proliferation. Multiple cell fates, including renewed stem cells and committed differentiating progenitors, are specified during this early window of activation. We further show that Sox2 is essential for cells to transition from the activated to neuronal progenitor states. Our study highlights strategies for stem cell mediated regeneration that may be conserved in other adult stem cell niches.

AB - This study aimed to investigate possible relationships between sedentary behavior and body mass index (BMI), cardiorespiratory fitness (CRF), and health-related quality of life (HRQoL) in schizophrenia patients. Variables contributing to the variability in sedentary behavior were identified. Eighty-two schizophrenia outpatients (mean age+/-SD: 41.0+/-8.7years, 87% men, mean illness duration+/-SD: 17.1+/-8.9years) wore a multisensor armband for 7 consecutive full days to objectively measure sedentary behavior. BMI, walking capacity (6-minute walking test) as a proxy for CRF estimation and HRQoL (Short Form 36-Item Health Survey questionnaire version 2) were also assessed. Correlation (Pearson or Spearman coefficients) and multiple regression analysis were used. Sedentary behavior was significantly associated with BMI, CRF, and the physical component summary score of HRQoL (r values, -0.34-0.41; all P<0.001) and remained significant after adjustments for age, illness duration, symptom severity, adherence to Mediterranean diet, smoking, and antipsychotic medication (all P<0.05). BMI, CRF and vitality were identified as determinants of sedentary behavior. Consistent relationships between sedentary behavior and BMI, CRF, and the physical component summary score of HRQoL were found in schizophrenia patients. All the identified determinants of sedentary behavior are modifiable and may be important areas for future interventions in this population. PMID- 29174338 TI - Authors' Reply. PMID- 29174337 TI - Arterial Thickness and Stiffness Are Independently Associated with Left Ventricular Strain. AB - BACKGROUND: The aim of this study was to examine the association between myocardial strain and arterial thickness and stiffness in young adults. Increased common carotid artery intima media thickness and peripheral arterial stiffness are known to precede coronary artery disease and cardiovascular (CV) events such as myocardial infarction and congestive heart failure. However, subclinical cardiac dysfunction can be detected in high-risk adults by myocardial strain echocardiography. The authors hypothesized that increased carotid artery intima media thickness would be associated with abnormal myocardial strain in young subjects who had obesity and type 2 diabetes mellitus. METHODS: CV risk factors were collected in 338 young adults participating in a prospective, cross sectional study. The CV parameters collected included intima-media thickness, peripheral arterial stiffness by brachial distensibility, and myocardial strain and strain rate. General linear models were constructed to determine if vascular structure and function measures were independently associated with myocardial strain and strain rate. RESULTS: A linear relationship was found between global longitudinal strain obtained from the four-chamber view and global strain rate in systole and carotid intima-media thickness (four-chamber global longitudinal strain: beta = 3.0, CV risk factor-adjusted R2 = 0.34; global strain rate in systole: beta = 0.0053, R2 = 0.21; P <= .0001) and between four-chamber global longitudinal strain and lower brachial distensibility (beta = -0.42, R2 = 0.22; P < .001). CONCLUSIONS: Adverse changes in vascular structure and function are simultaneously present with reduced myocardial systolic function. PMID- 29174339 TI - Feasibility of Left Ventricular Global Longitudinal Strain Measurements from Contrast-Enhanced Echocardiographic Images. AB - BACKGROUND: Although left ventricular global longitudinal strain (GLS) is an index of systolic function recommended by the guidelines, poor image quality may hamper strain measurements. While contrast agents are commonly used to improve endocardial visualization, no commercial speckle-tracking software is able to measure strain in contrast-enhanced images. This study aimed to test the accuracy of speckle-tracking software when applied to contrast-enhanced images in patients with suboptimal image quality. METHODS: We studied patients with a wide range of GLS values who underwent transthoracic echocardiography. Protocol 1 included 44 patients whose images justified use of contrast but still allowed noncontrast speckle-tracking echocardiography (STE), which was judged as accurate and used as a reference. Protocol 2 included 20 patients with poor image quality that precluded noncontrast STE; cardiac magnetic resonance- (CMR-) derived strain was used as the reference instead. Half the manufacturer recommended dose of a commercial contrast agent (Definity/Optison/Lumason) was used to provide partial contrast enhancement. Higher than normal mechanical indices (0.6-0.7) and lowest frequency range for maximal penetration settings were used for imaging. GLS was measured (Epsilon) with and without contrast-enhanced images and by CMR-derived feature tracking (TomTec). Comparisons included linear regression and Bland Altman analyses. RESULTS: The contrast STE analysis failed in 4/64 patients (6%). Manual corrections were needed to optimize tracking with contrast in all patients. GLS measurements were in good agreement between contrast and noncontrast images (r = 0.85; mean GLS in the contrast images, -12.9% +/- 4.7%; bias, 0.34% +/- 2.4%). Good agreement was also noted between contrast STE- and CMR-derived strain (r = 0.83; mean, GLS -13.5% +/- 4.0%; bias, 0.72% +/- 2.5%). CONCLUSIONS: We found that GLS measurements from contrast-enhanced images are feasible and accurate in most patients, even in those with poor image quality that precludes strain measurements without contrast enhancement. PMID- 29174340 TI - Echocardiographic Estimation of Mean Pulmonary Artery Pressure: A Comparison of Different Approaches to Assign the Likelihood of Pulmonary Hypertension. AB - BACKGROUND: Current guidelines advise using echocardiography for noninvasive estimation of the likelihood that a patient has pulmonary hypertension (PH). To estimate the echocardiographic probability of PH, the maximal tricuspid regurgitation velocity (TR Vmax) is recommended as the main parameter to use over more complex algorithms that provide an estimation of pulmonary artery pressure. This preference is based on concerns about inaccuracies and amplification of measurement errors that can occur from using derived variables. However, this has not been examined systematically. METHODS: A retrospective database analysis was performed of invasively determined measurements of right heart pressure in 90 patients, corresponding echocardiographic estimations of pulmonary artery pressure, and additional parameters obtained within 24 hours. Several algorithms were compared for their correlations and accuracy parameters. RESULTS: Although a Bland-Altman analysis demonstrated that all examined algorithms exhibited inaccuracies that could be clinically relevant in individuals, algorithms estimating mean pulmonary artery pressure (PAPm) on the basis of tricuspid regurgitation generally exhibited stronger correlations with invasively determined PAPm and more accurate identification of PH than did TR Vmax. Echocardiographic estimation of right atrial pressure >15 mm Hg exhibited the highest odds ratio for invasively confirmed PH, suggesting that this parameter is of additional diagnostic value. Indeed, algorithms that also considered right atrial pressure performed best, whereas empirical algorithms, TR Vmax, and methods relying on pulmonary acceleration time exhibited weaker performance. CONCLUSIONS: Although all methods are associated with inaccuracies, echocardiographically determined PAPm was superior to the current guideline recommendation of using TR Vmax with regard to its correlation with invasively determined PAPm and the presence of PH. PAPm may be considered as an alternative to TR Vmax for evaluating the echocardiographic probability of PH. PMID- 29174341 TI - Feasibility, Accuracy, and Reproducibility of Aortic Annular and Root Sizing for Transcatheter Aortic Valve Replacement Using Novel Automated Three-Dimensional Echocardiographic Software: Comparison with Multi-Detector Row Computed Tomography. AB - BACKGROUND: In transcatheter aortic valve replacement (TAVR), multi-detector row computed tomography (MDCT) is currently the standard imaging modality for correct prosthesis sizing, despite risks of radiation and contrast-induced renal injury. Three-dimensional (3D) transesophageal echocardiography (TEE) has been proposed as a potential alternative imaging technique, and recently, automated 3D transesophageal echocardiographic software (Aortic Valve Navigator [AVN], an unreleased prototype from Philips) has been developed for assessment of the aortic annulus and root. The aim of this study was to assess the feasibility, accuracy, and reproducibility of AVN measurements in TAVR candidates by performing a comparison with MDCT. METHODS: In 150 patients with severe, symptomatic aortic stenosis referred for TAVR, data on aortic annular and root dimensions prospectively acquired using 3D TEE and MDCT were retrospectively analyzed. Image quality on 3D TEE and the duration of analysis with AVN were recorded, as well as the aortic valve Agatston score on MDCT. RESULTS: Data were obtained using 3D TEE and MDCT in 100% of patients for aortic annular dimensions and in 89% for aortic root dimensions. The mean duration of analysis using AVN was 4.2 +/- 1.0 min, but it was significantly shorter with better 3D echocardiographic image quality and lower Agatston score on MDCT. Correlation of measurements between 3D TEE and MDCT was good to excellent for all anatomic locations (sinotubular junction mean diameter, R = 0.71; sinus of Valsalva mean diameter, R = 0.87; aortic annular mean diameter, R = 0.75; aortic annular perimeter, R = 0.83; aortic annular area, R = 0.91), with low inter- and intraobserver variability (intraclass correlation coefficient >= 0.93 and r >= 0.90 for all locations). Comparison based on conventional prosthesis sizing charts yielded excellent agreement in prosthesis size choice (kappa = 0.90). CONCLUSIONS: New automated 3D transesophageal echocardiographic software allows accurate modeling and reproducible quantification of aortic annular and root dimensions with high feasibility. An excellent correlation between measurements with AVN and MDCT and agreement in prosthesis sizing suggests the use of AVN in clinical practice as potential alternative to MDCT before TAVR.

AB - BACKGROUND: Higher fetuin-A expression is linked to both obesity and type 2 diabetes mellitus (T2DM), However, studies in non-obese patients with T2DM are scarce. METHODS: 345 newly diagnosed T2DM patients and 300 subjects with normal glucose tolerance (NGT) were divided into obese and non-obese subgroups, respectively. Serum fetuin-A and adiponectin levels and related parameters were measured. RESULTS: T2DM patients with obesity had higher fetuin-A levels compared with non-obese patients and obese NGT subjects (p<0.001). Significant correlations were observed between fetuin-A and most metabolic parameters in obese NGT and T2DM subjects, but which was not in non-obese patients with T2DM. The independent associations were found between fetuin-A and free fatty acids, HOMA-IR, C-reactive protein and adiponectin only in obese NGT and T2DM subjects (all p<0.05). The adjusted odds ratios for obesity were increased with increasing quartile of fetuin-A in both T2DM and NGT subjects in logistic regression models (p for trend<0.001), but which was more significant in T2DM patients. CONCLUSION: Higher serum fetuin-A levels in obese T2DM patients compared with non-obese patients and obese NGT subjects supports the hypothesis that fetuin-A may be as a bridge connecting obesity and obesity-related T2DM. PMID- 29174343 TI - Tim-3 expression predicts the abnormal innate immune status and poor prognosis of glioma patients. AB - Malignant glioma, the most common and devastating primary brain tumor, has serious effects on human health with high risk of recurrence and short survival periods. Recently, the exploitation of immunological mechanisms shed new lights for developing novel therapeutic strategies for glioma pathogenesis. Tim-3, a member of T cell immunoglobulin and mucin domain family, has been involved in multiple diseases, including tumor, by regulating the viability and function of immunocytes. In the present study, we detected Tim-3 expression on peripheral innate immunocytes from glioma patients and analyzed their correlation with clinical indices. We found that the number of CD3-CD56+ NK cells decreased in glioma patients. Compared with healthy controls, glioma patients had higher Tim-3 expression on peripheral CD3-CD56+ NK cells and CD14+ monocytes. Tim-3+ NK cells had decreased capability of IFN-r secretion, while Tim-3+ monocytes showed a M2 like phenotype. Importantly, Tim-3 level on both NK cells and monocytes positively correlated with the ratio of Ki-67+ tumor cells. Moreover, patients with high percentage of Tim-3+ monocytes showed high risk of recurrence or death. Our present work gives new insights into the innate immune mechanisms in glioma and might provide new evidences for the clinical practice of Tim-3-based immunotherapy in glioma. PMID- 29174344 TI - The role of plasma lipoprotein lipase, hepatic lipase and GPIHBP1 in the metabolism of remnant lipoproteins and small dense LDL in patients with coronary artery disease. AB - BACKGROUND: The relationship between plasma lipoprotein lipase (LPL), hepatic triglyceride lipase (HTGL), glycosylphosphatidylinositol anchored HDL binding protein1 (GPIHBP1) concentration and the metabolism of remnant lipoproteins (RLP) and small dense LDL (sdLDL) in patients with coronary artery disease (CAD) is not fully elucidated. METHODS: One hundred patients who underwent coronary angiography were enrolled. The plasma LPL, HTGL and GPIHBP1 concentrations were determined by ELISA. The time dependent changes in those lipases, lipids and lipoproteins were studied at a time-point just before, and 15min, 4h and 24h after heparin administration. RESULTS: The LPL concentration exhibited a significant positive correlation with HDL-C, and inversely correlated with TG and RLP-C. The HTGL concentration was positively correlated with RLP-C and sdLDL-C. The HTGL ratio of the pre-heparin/post-heparin plasma concentration and sdLDL C/LDL-C ratio were significantly greater in CAD patients than in non-CAD patients. GPIHBP1 was positively correlated with LPL and inversely correlated with RLP-C and sdLDL-C. CONCLUSION: The HTGL concentration was positively correlated with RLP-C and sdLDL-C, while LPL and GPIHBP1 were inversely correlated with RLP-C and sdLDL-C. These results suggest that elevated HTGL is associated with increased CAD risk, while elevated LPL is associated with a reduction of CAD risk. PMID- 29174346 TI - Self-reported adverse food reactions and anaphylaxis in the SchoolNuts study: A population-based study of adolescents. AB - BACKGROUND: Adolescents are at the highest risk of death from anaphylaxis, yet few population-based studies have described the frequencies and risk factors for allergic reactions caused by accidental allergen ingestion in this group. METHODS: We describe the prevalence, frequency, and associated risk factors for recent adverse food reactions in 10- to 14-year-olds in Melbourne, Australia, recruited from a stratified, random, population-based sample of schools (SchoolNuts, n = 9663; 48% response rate). Self-reported food allergy and adverse reaction details, including anaphylaxis, were identified by using a student questionnaire over the past year. RESULTS: Of 547 students with possible IgE mediated food allergy, 243 (44.4%; 95% CI, 40.3% to 48.7%) reported a reaction to a food. Fifty-three (9.7%; 95% CI, 7.2% to 12.2%) students reported 93 anaphylaxis episodes. Peanut and tree nuts were the most common food triggers. Among students with current IgE-mediated food allergy, those with resolved or current asthma (adjusted odds ratio [aOR], 1.9 [95% CI, 1.1-1.3] and 1.7 [95% CI, 1.1-2.6]) and those with more than 2 food allergies (aOR, 1.9 [95% CI, 1.1-3.1]) were at greatest risk of any adverse food reaction, and those with nut allergy were most at risk of severe reactions (aOR, 2.9 [95% CI, 1.1-4.4]). Resolved or current asthma was not associated with increased risk of severe reactions (aOR, 0.8 [95% CI, 0.3-2.2] and 1.6 [95% CI, 0.7-3.7]). CONCLUSIONS: Adolescents with food allergy are frequently exposed to food allergens. Those with asthma and more than 2 food allergies were at the greatest risk for adverse food reactions. Those with nut allergies were most at risk of severe reactions. PMID- 29174345 TI - Effective exercise intervention period for improving body function or activity in patients with knee osteoarthritis undergoing total knee arthroplasty: a systematic review and meta-analysis. AB - BACKGROUND: Various systematic reviews and/or meta-analyses examining the effects of pre- or postoperative exercise on body function or activity in patients undergoing total knee arthroplasty (TKA) have been published. However, the interventional period needed to at least improve outcomes is unknown. OBJECTIVE: The aim of this systematic review and meta-analysis was to investigate the exercise intervention period needed to effectively improve body function or activity before and after TKA in patients with knee osteoarthritis (OA). METHODS: Studies published until July 2017 were included in the review. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was applied to each meta-analysis to determine the quality of the evidence. RESULTS: Twenty-seven randomized controlled trials were identified. A meta-analysis indicated that exercises performed for 8 weeks after discharge in addition to standard postoperative intervention effectively improved body function as assessed using pain level; physical function, and stiffness on the Western Ontario and McMaster Universities Arthritis Index; extension strength; active knee flexion range of motion; timed up and go test; and gait speed. CONCLUSION: Overall, we found low- to moderate-quality evidence that an 8-week exercise period was needed after discharge to improve body function and activity in patients with knee OA undergoing TKA.

AB - Sexual assault (SA) is a major public health problem that leaves patients at risk for HIV. The gold standard of medical treatment for SA patients includes prophylactic treatment to prevent HIV. A meta-analysis was conducted and examined the rates of nonoccupational postexposure prophylaxis (n-PEP) offered to, accepted, and completed by SA patients who presented to emergency departments in the United States. Four points of data were analyzed: (a) SA patients who met the criteria and were offered n-PEP, (b) SA patients who were offered n-PEP and accepted the medication, (c) SA patients who accepted n-PEP treatment and completed at least one follow-up appointment, and (d) SA patients who completed the entire course of n-PEP. Results of the meta-analysis indicated that approximately half of the patients who were offered n-PEP accepted the medication. However, only 25.7% of SA patients who accepted n-PEP completed the full course. PMID- 29174348 TI - Addressing Prevention Among HIV-Uninfected Women in PMTCT Programs in South India. AB - With nearly one million HIV-infected women in India, prevention of mother-to child transmission (PMTCT) programs serve an important role. While PMTCT programs focus on mothers living with HIV infection, offering them to uninfected pregnant women may prevent maternal HIV infections. To inform future efforts to offer PMTCT programs to uninfected women, we conducted focus groups with 24 uninfected women in the South Indian state of Karnataka who had given birth within the previous 2 years to explore their perceptions and experiences about HIV education and screening during pregnancy. Although all the participants had undergone HIV testing at a public health facility during pregnancy, they reported little knowledge about HIV transmission or prevention. Revisions are needed in existing PMTCT program curricula and instruction methods before they can be offered to uninfected women as an HIV prevention strategy. PMID- 29174347 TI - Discovery of 5-((5-chloro-2-methoxyphenyl)sulfonamido)nicotinamide (SBI-425), a potent and orally bioavailable tissue-nonspecific alkaline phosphatase (TNAP) inhibitor. AB - Tissue-nonspecific alkaline phosphatase (TNAP) is an ectoenzyme crucial for bone matrix mineralization via its ability to hydrolyze extracellular inorganic pyrophosphate (ePPi), a potent mineralization inhibitor, to phosphate (Pi). By the controlled hydrolysis of ePPi, TNAP maintains the correct ratio of Pi to ePPi and therefore enables normal skeletal and dental calcification. In other areas of the body low ePPi levels lead to the development of pathological soft-tissue calcification, which can progress to a number of disorders. TNAP inhibitors have been shown to prevent these processes via an increase of ePPi. Herein we describe the use of a whole blood assay to optimize a previously described series of TNAP inhibitors resulting in 5-((5-chloro-2-methoxyphenyl)sulfonamido)nicotinamide (SBI-425), a potent, selective and oral bioavailable compound that robustly inhibits TNAP in vivo. PMID- 29174350 TI - Predicting Pediatric Patients Who Require Care at a Trauma Center: Analysis of Injuries and Other Factors. AB - BACKGROUND: Triage decision correctness for children in motor vehicle crashes can be affected by occult injuries. There is a need to develop a transfer score (TS) metric for children that can help quantify the likelihood that an injury is present that would require transfer to a trauma center (TC) from a non-TC, and improve triage decision making. Ultimately, the TS metric might be useful in an advanced automatic crash notification algorithm, which uses vehicle telemetry data to predict the risk of serious injury after a motor vehicle crash using an approach that includes metrics to describe injury severity, time sensitivity, and predictability. STUDY DESIGN: Transfer score metrics were calculated in 4 pediatric age groups (0 to 4, 5 to 9, 10 to 14, 15 to 18 years) for the most frequent motor vehicle crash injuries using the proportions of children transferred to a TC or managed at a non-TC using the National Inpatient Sample years 1998 to 2007. To account for the maximum Abbreviated Injury Scale (MAIS) injury, a co-injury adjusted transfer score (TSMAIS) was calculated. The TS and TSMAIS range from 0 to 1, with 1 indicating highly transferred injuries. RESULTS: Injuries in younger patients were more likely to be transferred (median TS 0.48, 0.35, 0.25, and 0.23 for 0 to 4, 5 to 9, 10 to 14, and 15 to 18 years, respectively). Injuries more likely to be transferred in younger children occurred in the thorax and abdomen. Regardless of age, spine (median TSMAIS 0.59), head (median TSMAIS 0.48), and thorax (median TSMAIS 0.46) injuries had the highest frequency for transfer. CONCLUSIONS: The TS metrics quantitatively describe age-specific transfer practices for children with particular injuries. This information can be useful in advanced automatic crash notification systems to alert first responders to the possibility of occult injuries and reduce undertriage of commonly missed injuries.

AB - As one of the most important environmental factors, oxygen is particularly important for synthesis of n-3 polyunsaturated fatty acids (n-3 PUFA) in microalgae. In general, a higher oxygen supply is beneficial for cell growth but obstructs PUFA synthesis. The generation of reactive oxygen species (ROS) under aerobic conditions, which leads to the peroxidation of lipids and especially PUFA, is an inevitable aspect of life, but is often ignored in fermentation processes. Irritability, microalgal cells are able to activate a number of anti oxidative defenses, and the lipid profile of many species is reported to be altered under oxidative stress. In this review, the effects of oxygen on the PUFA synthesis, sources of oxidative damage, and anti-oxidative defense systems of microalgae were summarized and discussed. Moreover, this review summarizes the published reports on microalgal biotechnology involving direct/indirect oxygen regulation and new bioreactor designs that enable the improved production of PUFA. PMID- 29174353 TI - A new enrichment diagnostic platform for semen culture. AB - Urogenital bacterial infections have been described in literature as a potential cause of infertility. For the consequences that a failure in diagnosis could have on the evolution of male urogenital infectious disease, an accurate microbiological procedure to investigate the bacterial species composition of seminal fluid plays a crucial role to better understand the eventual correlation with infertility. In order to improve the quality of semen culture investigations, we have developed a new enrichment diagnostic platform. Semen samples of 540 infertile men were simultaneously analyzed using the standard microbiological semen culture method and an alternative new experimental technique (Brain Heart Infusion broth, BHI, enrichment). Our results established the possibility to apply BHI enrichment to detect bacteria from semen samples with higher sensitivity (100%) and negative predictive value (100%) than the standard technique. PMID- 29174354 TI - Purification and characterization of novel bi-functional GH3 family beta xylosidase/beta-glucosidase from Aspergillus niger ADH-11. AB - beta-Xylosidase plays an important role in xylan degradation by relieving the end product inhibition of endo-xylanase caused by xylo-oligosaccharides. beta Xylosidase has a wide range of applications in food, feed, paper and pulp, pharmaceutical industries and in bioconversion of lignocellulosic biomass. Hence, in the present study focused on purification, biochemical characterization and partial sequencing of purified beta-xylosidase from xylanolytic strain Aspergillus niger ADH-11. Acetone precipitation followed by GPC using Sephacryl S 200 yielded 20.59-fold purified beta-xylosidase with 58.30% recovery. SDS-PAGE analysis of purified beta-xylosidase relieved a monomeric subunit with a molecular weight 120.48kDa. Kinetic parameters of purified beta-xylosidase viz Km, Vmax, Kcat and catalytic efficiency were assessed. Purified beta-xylosidase was additionally active on p-nitrophenyl-beta-d-glucopyranoside substrate also. Moreover, peptide mass fingerprinting analysis support our biochemical studies and showed that the purified protein is a novel beta-xylosidase with beta glucosidase activity and belongs to the bi-functional GH3 superfamily. Besides, tolerance of purified beta-xylosidase towards glucose and xylose was also assessed. PMID- 29174355 TI - A novel inhibition based biosensor using urease nanoconjugate entrapped biocomposite membrane for potentiometric glyphosate detection. AB - A potentiometric biosensor based on agarose-guar gum (A-G) entrapped bio nanoconjugate of urease with gold nanoparticles (AUNps), has been reported for the first time for glyphosate detection. The biosensor is based on inhibition of urease activity by glyphosate, which was measured by direct potentiometry using ammonium ion selective electrode covered with A-G-urease nanoconjugate membrane. TEM and FTIR analysis revealed nanoconjugate formation and its immobilization in A-G matrix respectively. The composite biopolymer employed for immobilization yields thin, transparent, flexible membrane having superior mechanical strength and stability. It retains the maximum activity (92%) of urease with negligible leaching. The conjugation of urease with AUNps allows improvement in response characteristics for potentiometric measurement. The biosensor shows a linear response in the glyphosate concentration range from 0.5ppm-50ppm, with limit of detection at 0.5ppm, which covers maximum residual limit set by WHO for drinking water. The inhibition of catalytic activity of urease nanoconjugate by gyphosate was confirmed by FTIR analysis. The response of fabricated biosensor is selective towards glyphosate as against various other pesticides. The biosensor exhibits good performance in terms of reproducibility and prolonged storage stability of 180days. Thus, the present biosensor provides an alternative method for simple, selective and cost effective detection of glyphosate based on urease inhibition. PMID- 29174356 TI - Separation, purification, structures and anticoagulant activities of fucosylated chondroitin sulfates from Holothuria scabra. AB - In this study, a new fucosylated chondroitin sulfate (HsG) with an average molecular weight of 69.1 kDa was isolated from sea cucumber Holothuria scabra. We investigated the structure of the HsG by adopting monosaccharide composition analysis, disaccharide composition analysis, IR,1H and13C NMR spectra and methylation analysis. According to methylation results of desulfated/carboxyl reduced polysaccharides and the analysis of unsaturated disaccharides generated through the enzymolysis of the defucosed polysaccharides, it is shown that each branch is formed by one fucopyranosyl residue, wherein 55.7% of the fucopyranosyl residues are linked to the O-6 position of the N-acetylgalactosamine moiety, 21.2% of the fucopyranosyl residues are linked to the O-3 position of beta-d glucuronic acid, 13.0% of the fucopyranosyl residues are linked to the O-4 positions of the N-acetylgalactosamine moiety, and 10.1% of the fucopyranosyl residues are not linked to sulfate groups on the backbone. The backbone >4)GlcUAbeta(1 -> 3)GalNAcbeta(1-> and sulfated fucose branches were composed of the beta-d-glucuronic acid, N-acetyl-beta-d- galactosamine, alpha-l-fucose and sulfate groups by the molar ratio of 1:1.72:2.34:3.29. The anticoagulant activities of the HsG was evaluated and compared with heparin. The result showed that the HsG could prolong the activated partial thromboplastin time. PMID- 29174357 TI - A novel detergent additive: Organic solvent- and thermo-alkaline-stable recombinant subtilisin. AB - In the present work, subtilisin gene from Bacillus subtilis PTTC 1023 was synthesized, cloned into the vector pD441-NH and expressed in E. coli BL21 (DE3). Recombinant subtilisin was purified in a single-step procedure by affinity chromatography. The molecular mass of the purified protein was determined to be about 40kDa by SDS-PAGE. The optimum pH and temperature values of its proteolytic activity were 10.5 and 50 degrees C, respectively and retained more than 70% and 89% of its activity in pH range of 7-12 and 30-60 degrees C, respectively. Enzyme purity was estimated to be about 200- fold greater than that of the crude extract and subtilisin had a specific activity of 56.16U/mg, with a yield of about 87.9%. It was completely inhibited by phenylmethanesulfonyl fluoride, which strongly suggests its belonging to serine protease family. Interestingly, subtilisin protease displayed a significant compatibility with commercial detergents, and tolerance organic solvents, metallic ions and surfactants. The findings obtained demonstrated that protease of B. subtilis could potentially be used in future applications as an additive in detergent formulations. PMID- 29174358 TI - Structure analysis of a heteropolysaccharide from fruits of Lycium barbarum L. and anti-angiogenic activity of its sulfated derivative. AB - Angiogenesis plays a crucial role in tumor growth and development. Blocking angiogenesis of tumor cells has become one of the most promising approaches in cancer therapy. Here, an acidic polysaccharide designated LBP1B-S-2 with an average molecular weight of 80.00kDa, was extracted and purified from dried mature fruits of Lycium barbarum L. by DEAE SepharoseTM Fast Flow and Sephacryl S 300 HR columns. Monosaccharide composition analysis indicated that the LBP1B-S-2 was composed of rhamnose, arabinose, galactose and glucuronic acid in a molar ratio of 3.13: 53.55: 39.37: 3.95. The backbone of LBP1B-S-2 was consisted of 1, 3-linked beta-d-Galp, 1, 6-linked beta-d-Galp and branches contained 1, 4-linked beta-d-GlcpA, T-linked beta-d-Galp, 1, 6-linked beta-d-Galp, T-linked alpha-l Araf, T-linked beta-l-Araf, 1, 5-linked alpha-l-Araf and T-linked beta-l-Rhap directly or indirectly attached to C-3 position of 1, 6-linked beta-d-Galp or C-6 position of 1, 3-linked beta-d-Galp, according to the results of partial acid hydrolysis analysis, methylation analysis, IR and NMR spectra. The sulfated derivative of LBP1B-S-2, could significantly inhibit the tube formation of human microvascular endothelial cells (HMEC-1) in vitro at concentration of (95nM) without significant cytotoxicity. PMID- 29174360 TI - Impact of ionic liquid type on the structure, morphology and properties of silk cellulose biocomposite materials. AB - Microcrystalline cellulose and Bombyx mori silk blended biocomposite films were regenerated using various imidazolium-based ionic liquids. The films were characterized to understand the effect of the inter- and intra-molecular interactions upon the morphology and thermal properties. Various techniques were implemented to investigate structural, morphological and thermal properties of the biocomposite films, including Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC) and X-ray scattering. Results show that the type of ionic liquid has strong influence on the structure of silk-cellulose composites that can form either amorphous or semicrystalline structures. While the thermal properties are independent of the type of cation in ionic liquids, the levels of beta-sheet configuration are dependent on the type of anion, which further causes changes on the biocomposite thermal properties. The topological image provided information to support morphological effects on the varying ionic liquids and X-ray scattering allowed for insight on the role of ionic liquids on the crystallinity and the spacing differences in biocomposite films. The results have demonstrated that there is a direct relationship between the intermolecular interactions in films and the anion structure of the ionic liquids. PMID- 29174359 TI - Expression of catalytically efficient xylanases from thermophilic fungus Malbranchea cinnamomea for synergistically enhancing hydrolysis of lignocellulosics. AB - In this study, two xylanase genes (GH10 and GH11) derived from Malbranchea cinnamomea, designated as XYN10A_MALCI and XYN11A_MALCI, respectively, were expressed in Pichia pastoris X33. The maximum level of xylanase expression was found to be 24.3U/ml for rXYN10A_MALCI and 573.32U/ml for rXYN11A_MALCI. The purified recombinant rXYN11A_MALCI was stable at 70 degrees C and catalytically active against a variety of substituted (arabinoxylans) as well as unsubstituted xylans. The hydrolytic potential of recombinant xylanases for enhancing the hydrolysis of acid/alkali pretreated lignocellulosics (rice straw and bagasse) by the commercial cellulase Cellic CTec2 was assessed which revealed that both rXYN10A_MALCI and rXYN11A_MALCI act synergistically with commercial cellulases and resulted in 1.54 and 1.58 folds improved hydrolysis of acid treated rice straw and alkali treated rice straw using cocktail comprising of Cellic CTec2 and XYN11A_MALCI (8:2 ratio) when compared to Cellic CTec2 alone at same protein loading rate of (~5.7mg/g biomass). PMID- 29174362 TI - Rupture of sinus of Valsalva aneurysm: Two case reports and a concise review of the literature. AB - BACKGROUND: The rupture of sinus of Valsalva aneurysm (RSoVA) is a rare disorder that affects the integrity of the cardiovascular system, disrupting its dynamics and resulting in a variety of manifestations. In this report, we discuss two cases of RSoVA that we encountered and review similar cases reported in the literature. METHODS: literature review of reported cases of RSoVA in PubMed and Google Scholar. RESULTS: A total of 223 cases were found and the final analysis included 225 cases, of which 69% occurred in males and the mean age was 38.9 years. Dyspnea was the most common presenting symptom and 76% of the cases described continuous murmur on examination. The right sinus was affected in 61% of the cases and the fistula connected to the right chambers of the heart 73% of the time. CONCLUSION: RSoVA is a rare condition that is difficult to diagnose, it should be considered in the right context, particularly in young patients with symptoms of heart failure and the presence of continuous murmur on cardiac examination. PMID- 29174363 TI - Prognostic significance of late gadolinium enhancement on cardiac magnetic resonance in patients with hypertrophic cardiomyopathy. AB - BACKGROUND: Late gadolinium enhancement (LGE) on cardiac MRI indicates the myocardial fibrosis in hypertrophic cardiomyopathy (HCM), and the prognostic value of LGE in HCM has been described in several studies, but controversy exists given the limited power of these studies to predict future adverse cardiac events. The objective of this study was to perform a meta-analysis to systematically evaluate the predictive value of LGE on cardiac magnetic resonance (CMR) for future adverse cardiac events. METHODS: We systematically searched multiple database including PubMed, EMBASE, and Cochrane Library for cohort studies of the effects of LGE on clinical outcomes (sudden cardiac death (SCD)/aborted SCD, all cardiac death, and all-cause mortality) in patients with HCM. We performed a meta-analysis to determine pooled odds ratios (OR), weighted average annualized event rates, and summary receiver-operating characteristic (SROC) curves for these clinical events. RESULTS: We identified nine clinical studies, examining 1734 patients with LGE and 2036 without LGE, and an average follow-up of 2.9 years. The weighted average annualized event rates of SCD/aborted SCD in patients with HCM (positive LGE versus negative LGE) was 1.28% versus 0.32% (p < 0.001), and the pooled OR was 3.40 (95% CI: 1.90, 6.08; p < 0.001). The sensitivity and specificity of predicting future cardiac events were 0.83 (95% CI: 0.66, 0.93) and 0.45 (95% CI: 0.31, 0.59), respectively. The 5-year risk of SCD/aborted SCD was 6.4% in patients with LGE. The all cardiac death and all-cause mortality were also significantly increased in patients with LGE. However, the extent of LGE was not significantly related to the risk of SCD/aborted SCD. CONCLUSIONS: LGE is significantly associated with SCD/aborted SCD risk, all cardiac death and all-cause mortality in patients with HCM. Implantable cardioverter defibrillators (ICD) can be considered for those patients with LGE. PMID- 29174361 TI - Glycol chitosan assisted in situ reduction of gold on polymeric template for anti cancer theranostics. AB - Multifunctional biodegradable nanomaterials that could be used for both imaging and therapy are being researched extensively. A simple technique to synthesize multifunctional nanoparticles without compromising on any of their functionality is a challenge. We have attempted to optimize a two-step procedure of gold coated polymeric template involving 1) Single pot synthesis of PLGA nanoparticles with cationic surface charge using glycol chitosan and 2) in situ gold coating for formation of gold coated PLGA nanoshell (AuPLGA-NS). These gold-coated PLGA nanoparticles were explored for photothermal therapy (PTT) and as X-ray/CT contrast agents. Biocompatibility and photothermal cytotoxicity of AuPLGA-NS were evaluated in-vitro and results confirmed the therapeutic efficacy of these particles resulting in 80% cancer cell death. Besides, it also showed potential X ray/CT imaging ability with contrast equivalent to that of Iodine. The results demonstrated that these gold-coated PLGA nanoparticles synthesized by a simple approach could be used as a multifunctional nanosystem for cancer theranostics. PMID- 29174364 TI - Identification and characterization of interchangeable cross-species functional promoters between Babesia gibsoni and Babesia bovis. AB - The development of transgenic techniques has been reported in many protozoan parasites over the past few years. We recently established a successful transient transfection system for Babesia gibsoni based on Bg 5'-ef-1alpha promoter. This study investigated 6 homologous and 6 heterologous promoters for B. gibsoni and B. bovis and identified novel interchangeable cross-species functional promoters between B. gibsoni and B. bovis. Ten out of twelve promoters had heterologous promoter function. In particular, Bg 5'-ef-1alpha and Bg 5'-actin heterologous promoters resulted in a significantly higher luciferase activity than Bb 5'-ef 1alpha homologous promoter in B. bovis. The present study showed that Bg 5'-actin promoted the highest luciferase activity in both B. gibsoni and B. bovis. The study further indicates that heterologous promoter function widely exists between B. gibsoni and B. bovis. This finding is an important step for future stable transfection construct design and for the production of vaccines based on transfected B. gibsoni and B. bovis parasites. PMID- 29174365 TI - Rickettsia diversity in southern Africa: A small mammal perspective. AB - Worldwide, including Africa, rickettsioses are recognized as emerging or re emerging infections. To date, little is known about the diversity of Rickettsia species that are naturally associated with small mammals in southern Africa. The aim of the study was to screen a diversity of small mammals for the presence of rickettsial DNA. Animals were trapped at 38 localities in South Africa and Namibia. In total, 1616 ear-tissue samples from 23 species representing 17 genera were tested using real-time (rt)PCR and multi-locus sequence typing (MLST). Of the 1616 samples 251 (15.5%) were positive in an initial rtPCR. In 16 of the 23 investigated animal species rickettsial DNA was detected with an average prevalence of 15.7%. We herein describe for the first time four Rickettsia (R.) species known to be pathogenic for humans in rodents from South Africa, R. conorii, R. massiliae, R. felis and R. helvetica. In addition, by MLST and subsequent phylogenetic analyses so far undescribed Rickettsia species, Candidatus Rickettsia africaustralis, Candidatus Rickettsia rhabdomydis, and Candidatus Rickettsia muridii were confirmed. Further four new genotypes, genotype Rickettsia hofmannii, genotype Rickettsia stutterheimensis, genotype Rickettsia hogsbackensis and genotype Rickettsia kaalplaasensis, respectively, are described. The data indicate a surprisingly high diversity of Rickettsia in small mammals in South Africa and might indicate their possible role as reservoirs for Rickettsia. Ecological questions concerning their natural hosts such as small mammals, but also the role of livestock or pet animals, require further investigation. Particularly, data on the relevance of these rickettsiae for diseases in humans are of further interest. PMID- 29174366 TI - DNAJC12 deficiency: A new strategy in the diagnosis of hyperphenylalaninemias. AB - Patients with hyperphenylalaninemia (HPA) are detected through newborn screening for phenylketonuria (PKU). HPA is known to be caused by deficiencies of the enzyme phenylalanine hydroxylase (PAH) or its cofactor tetrahydrobiopterin (BH4). Current guidelines for the differential diagnosis of HPA would, however, miss a recently described DNAJC12 deficiency. The co-chaperone DNAJC12 is, together with the 70kDa heat shock protein (HSP70), responsible for the proper folding of PAH. All DNAJC12-deficient patients investigated to date responded to a challenge with BH4 by lowering their blood phenylalanine levels. In addition, the patients presented with low levels of biogenic amine in CSF and responded to supplementation with BH4, L-dopa/carbidopa and 5-hydroxytryptophan. The phenotypic spectrum ranged from mild autistic features or hyperactivity to severe intellectual disability, dystonia and parkinsonism. Late diagnosis result in permanent neurological disability, while early diagnosed and treated patients develop normally. Molecular diagnostics for DNAJC12 variants are thus mandatory in all patients in which deficiencies of PAH and BH4 are genetically excluded.

AB - BACKGROUND: McArdle disease (glycogen storage disease type V) is an inborn error of skeletal muscle metabolism, which affects glycogen phosphorylase (myophosphorylase) activity leading to an inability to break down glycogen. Patients with McArdle disease are exercise intolerant, as muscle glycogen-derived glucose is unavailable during exercise. Metabolic adaptation to blocked muscle glycogenolysis occurs at rest in the McArdle mouse model, but only in highly glycolytic muscle. However, it is unknown what compensatory metabolic adaptations occur during exercise in McArdle disease. METHODS: In this study, 8-week old McArdle and wild-type mice were exercised on a treadmill until exhausted. Dissected muscles were compared with non-exercised, age-matched McArdle and wild type mice for histology and activation and expression of proteins involved in glucose uptake and glycogenolysis. RESULTS: Investigation of expression and activation of proteins involved in glycolytic flux revealed that in glycolytic, but not oxidative muscle from exercised McArdle mice, the glycolytic flux had changed compared to that in wild-type mice. Specifically, exercise triggered in glycolytic muscle a differentiated activation of insulin receptor, 5' adenosine monophosphate-activated protein kinase, Akt and hexokinase II expression, while inhibiting glycogen synthase, suggesting that the need and adapted ability to take up blood glucose and use it for metabolism or glycogen storage is different among the investigated muscles. CONCLUSION: The main finding of the study is that McArdle mouse muscles appear to adapt to the energy crisis by increasing expression and activation of proteins involved in blood glucose metabolism in response to exercise in the same directional way across the investigated muscles. PMID- 29174368 TI - An Integrative Review of Interventions to Support Parents When Managing Their Child's Pain at Home. AB - To identify interventions aimed at helping parents manage their child's pain at home and to establish which aspects of interventions were effective. Integrative narrative review. MEDLINE, CINAHL Plus, PsychINFO, PsychArticles, AMED, PubMed, Scopus and Web of Knowledge databases were searched in 2016. This narrative synthesis followed Centre for Reviews and Dissemination and Economic and Social Research Council guidance. Reasons attributed to intervention success were analyzed using content analysis. From 2,534 papers, 17 were included. A majority were randomized controlled trials (n = 13) and most addressed postoperative pain (n = 15). A range of interventions were found that directly targeted parents, including child-parent interactions and health care professional-parent interactions, as well as complex interventions. Three studies were successful in reducing child pain at home and seven in increasing appropriate analgesic drug administration. Analysis of reasons attributed to interventions success revealed characteristics of interventions, components of parental pain management, and key features of research that aid researchers in designing and evaluating interventions. Risk of bias was present because of inadequate randomization, lack of a control group, and underpowered studies. Nurses should be aware that targeting parents directly is the most effective way of reducing child pain at home. Nurses need to advocate for effective analgesics for their child patients because the ineffectiveness of many interventions was attributed to inadequate analgesic drugs. Once this is achieved, success in increasing analgesic drug administration is most likely reached via parent-targeted interventions and those targeting health care professional-parent interactions. Successful interventions will be tailored to the child and adequately powered. Including a measure of sedation will ensure sedation is not mistaken for analgesic effectiveness. Interventions should address multiple facets of pain management and include a measure of pain over a period as opposed to a snapshot in time.

AB - Vascular anomalies are variably associated with overgrowth, skeletal anomalies, and abnormalities of the brain, leptomeninges, and eye. We assembled a 16 institution network to determine the range of genetic variants associated with a spectrum of vascular anomalies with overgrowth, ranging from mild to severe. Because of the overlap between cancer-associated variants and previously described somatic variants in vascular overgrowth syndromes, we employed tumor genetic profiling via high-depth next-generation sequencing using a panel to assay affected tissue from a diverse cohort of subjects with vascular anomalies with overgrowth. Seventy-five percent (43/57) harbored pathogenic or likely pathogenic variants in 10 genes. We identified two genes (mTOR, PIK3R1) and several variants previously described in the setting of cancer but that, to our knowledge, have not been described in vascular malformations. All were identified at low variant allele frequency consistent with somatic mosaic etiology. By leveraging somatic variant detection technology typically applied to cancer in a cohort inclusive of broad phenotypic severity, we demonstrated that most vascular anomalies with overgrowth harbor postzygotic gain-of-function mutations in oncogenes. Furthermore, continued interrogation of oncogenes in benign developmental disorders could provide insight into fundamental mechanisms regulating cell growth. PMID- 29174370 TI - Decreased Skin Barrier Lipid Acylceramide and Differentiation-Dependent Gene Expression in Ichthyosis Gene Nipal4-Knockout Mice. AB - NIPAL4 is one of the causative genes for autosomal recessive congenital ichthyosis. However, the role of NIPAL4 in skin barrier formation and the molecular mechanism of ichthyosis pathology caused by NIPAL4 mutations, have not yet been determined. Here, we found that Nipal4-knockout (KO) mice exhibited neonatal lethality due to skin barrier defects. Histological analyses showed several morphological abnormalities in the Nipal4-KO epidermis, including impairment of lipid multilayer structure formation, hyperkeratosis, immature keratohyalin granules, and developed heterochromatin structures. The levels of the skin barrier lipid acylceramide were decreased in Nipal4-KO mice. Expression of genes involved in skin barrier formation normally increases during keratinocyte differentiation, in which chromatin remodeling is involved. However, the induction of Krt1, Lor, Flg, Elovl1, and Dgat2 was impaired in Nipal4-KO mice. NIPAL4 is a putative Mg2+ transporter, and Mg2+ concentration in differentiated keratinocytes of Nipal4-KO mice was indeed lower than that of wild type mice. Our results suggest that low Mg2+ concentration causes aberration in the proper chromatin remodeling process, which in turn leads to failure of differentiation-dependent gene induction in keratinocytes. Our findings provide insights into Mg2+-dependent regulation of gene expression and skin barrier formation during keratinocyte differentiation.

AB - Although the expression of programmed death-ligand 1 (PD-L1) is an important mechanism by which cancer cells evade the immune system, PD-L1 expression in cancer cells is commonly associated with patients' responses to treatment with anti-programmed death 1/PD-L1 antibodies. However, how PD-L1 expression is regulated in melanoma cells remains to be fully elucidated. Here we report that the class I histone deacetylase (HDAC) HDAC8 controls transcriptional activation of PD-L1 by a transcription complex consisting of transcription factors homeobox A5 and signal transducer and activator of transcription 3. Inhibition of HDAC8 upregulated PD-L1 in melanoma cells. This was due to an increase in the activity of a fragment of the PD-L1 gene promoter that is enriched with binding sites for both homeobox A5 and signal transducer and activator of transcription 3. Indeed, knockdown of homeobox A5 or signal transducer and activator of transcription 3 abolished upregulation of PD-L1 by HDAC8 inhibition. Moreover, homeobox A5 and signal transducer and activator of transcription 3 were physically associated and appeared interdependent in activating PD-L1 transcription. Functional studies showed that HDAC8-mediated regulation of PD-L1 expression participated in modulating anti-melanoma T-cell responses. Collectively, these results identify HDAC8 as an important epigenetic regulator of PD-L1 expression, with implications for better understanding of the interaction between melanoma cells and the immune system.

PMID- 29174374 TI - Tracheobronchial stenting for airway malacia. AB - Tracheobronchomalacia is a rare but clinically troublesome condition in paediatrics. The softening of the major airways - which can include some or all of the tracheobronchial tree can lead to symptoms ranging from the minor (harsh barking cough, recurrent chest infections) to severe respiratory difficulties including prolonged ventilator support and 'near death attacks'. The causes are broadly divided into intrinsic softening of the airway wall which is considered a primary defect (e.g. syndromes; post tracheo-oesophageal fistula repair; extreme prematurity) or secondary malacia due to external compression from vascular structures or cardiac components. These secondary changes can persist even when the external compression is relieved, for example, following the repair of a pulmonary artery sling or double aortic arch. For children with severe clinical symptoms attributed to malacia, consideration is given to possible surgical remedies such as an aortopexy for short limited areas of malacia, or long term positive pressure support with CPAP either by non invasive or tracheostomy interface. More recently the role of stenting in children is receiving attention, especially with the development of newer techniques such as bioabsorbable stents which buy time for a natural history of improvement in the malacia to occur. This paper reviews the stents available and discusses the pros and cons of stenting in paediatric airway malacia.

AB - ETHNOPHARMACOLOGICAL RELEVANCE: Actinidia arguta (A. arguta) has been widely used in Asian countries as a traditional medicinal herb to treat inflammation-related diseases, such as gastritis, bronchitis, and arthritis. AIM OF THE STUDY: The inhibitory effect of A. arguta leaves' extract (AA) on inflammasome activation was investigated to verify its traditional use in treating inflammation-related diseases. MATERIALS AND METHODS: Bone marrow-derived macrophages (BMDMs) primed by lipopolysaccharide (LPS) were activated by selective inflammasome stimulators, and the effect of AA on inflammasome activation was investigated. A monosodium urate crystal (MSU)-induced peritonitis mouse model was used to study the in vivo efficacy of AA on inflammasome activation. RESULTS: In the in vitro study, AA regulated NLRP3 ubiquitination and apoptosis-associated speck-like protein containing a CARD (ASC) oligomerization, leading to the inhibition of NLRP3 inflammasome-mediated interleukin (IL)-1beta secretion. The inhibitory effect of AA on inflammasome activation in vitro was further confirmed in vivo using an MSU induced peritonitis mouse model. CONCLUSION: AA provided scientific evidence, substantiating the traditional claims for its use in the treatment of inflammation and inflammation-mediated metabolic disorders, including gout. PMID- 29174376 TI - Evidence of reduced bladder capacity during nighttime in children with monosymptomatic nocturnal enuresis. AB - INTRODUCTION: Bladder capacity in children with nocturnal enuresis is assessed by maximal voided volumes (MVV) obtained through daytime frequency volume (FV) charts. Although a degree of association has been demonstrated, daytime MVV does not consistently correspond with the nocturnal bladder capacity (NBC) in monosymptomatic nocturnal enuresis (MNE). It was hypothesized that isolated reduced NBC is a common phenomenon in children with nocturnal enuresis, despite normal daytime bladder function. OBJECTIVE: The aim of this study was to evaluate NBC in children with MNE and normal daytime voided volumes. Specifically, it aimed to determine the prevalence and degree of reduced NBC when using nocturnal urine production (NUP) during wet nights as a surrogate estimate of NBC. Furthermore, it aimed to investigate the relationship between NBC and desmopressin response. MATERIALS AND METHODS: Data from 103 children aged 5-15 years consecutively treated for MNE in a tertiary referral centre and with normal MVV on daytime FV charts were collected for this cohort study. Home recordings were completed for 2 weeks at baseline and during desmopressin dose titration. Estimated nocturnal bladder capacity (eNBC) was assessed separately each night as the total NUP causing a wet night. If NUP during a wet night was less than MVV, it was considered to be reduced eNBC during that particular night. RESULTS: Surprisingly, 82% (n = 84) of the children with MNE and normal daytime MVV experienced at least one wet night, with NUP below the daytime MVV indicative of a reduced eNBC. For 84 patients, mean percentage of wet nights with reduced eNBC (NUP below MVV) was 49% (SD +/- 31). A total of 11% of children with frequently reduced eNBC (>40% of wet nights with reduced eNBC) responded to desmopressin (Summary Fig.). Of the children with frequently reduced NBC, 91% experienced wet nights, with NUP <65% of expected bladder capacity (EBC). CONCLUSIONS: A significant proportion of children with MNE and normal MVV during the daytime frequently experienced wet nights, with a NUP well below their MVV and even <65% of EBC. This indicated that bladder reservoir dysfunction during sleep is relatively common in MNE. This abnormality was not reflected on daytime recordings, and thus nighttime data with NUP must be collected. This phenomenon may explain treatment failure to desmopressin, despite adequate antidiuretic response. PMID- 29174377 TI - Testosterone prior to hypospadias repair: Postoperative complication rates and long-term cosmetic results, penile length and body height. AB - INTRODUCTION: The use of hormonal therapy was first described in 1971 before hypospadias surgery, and it has been debated ever since. The long-term outcomes after puberty of patients treated with pre-operative testosterone in childhood are lacking. OBJECTIVES: Possible long-term effects of testosterone are often asked about in daily practice. The current study investigated the long-term outcomes regarding height, penile length and penile cosmesis in adult men after hypospadias surgery in childhood with and without pre-operative testosterone. METHODS: Adult men (n = 121) who underwent primary hypospadias repair in childhood were included. Pre-operative penile appearance, judged by a paediatric urologist, determined the use of pre-operative testosterone. Data on hypospadias characteristics, healing complications, surgical repair, and testosterone use were collected retrospectively. At adult age, stretched penile length and body height were measured, and penile cosmesis was evaluated using the Pediatric Penile Perception Score (PPPS). RESULTS: Postoperative complication rates in patients (n = 121) with and without testosterone were similar (50% vs. 43%; P = 0.54). Sixty adult patients (50%) with a median age of 19.8 years and follow-up time of 18.3 years were examined at the outpatient clinic at adult age. Of this group, testosterone was applied in 12/43 patients with distal, 3/6 patients with midshaft, and 9/11 patients with proximal hypospadias. Adult stretched penile length (12.0 cm vs. 12.4 cm; P = 0.47) and adult height (180.1 cm vs. 179.0 cm P = 0.65) showed no difference between patients with and without testosterone treatment. Penile cosmesis was (very) satisfactory in all PPPS domains, and showed no difference between the testosterone group and the non-testosterone group. Univariate and multivariate analysis was conducted to determine if the hypospadias type or pre-operative testosterone therapy had more influence on the long-term outcomes. None of the long-term outcomes were significantly associated with pre-operative testosterone therapy on multivariate analysis. DISCUSSION: This was the first study reporting long-term outcomes of hypospadias patients after puberty who received pre-operative hormonal therapy. Validated instruments were used as much as possible. Shortcomings of this study were the 50% response rate, the retrospective design, and the lack of objective inclusion criteria reported to indicate pre-operative testosterone therapy. CONCLUSION: This study suggested that the long-term results of patients receiving pre-operative testosterone treatment, who often had more challenging hypospadias, were similar to those who did not. However, a randomised controlled study is needed to confirm these results. PMID- 29174379 TI - A new pathway to eSCAPe lipotoxicity. AB - The molecular mechanisms underlying fatty liver progression towards more severe syndromes are complex and only partially understood. Studies have recently reported that lipotoxic fatty acid metabolites are instrumental in the development of hepatocyte injury in the context of fatty liver disease. The recent study by Papazyan et al. published in Cell Metabolism (2016;24(6):863-874) addresses this issue and reveals that rescuing de novo fatty acid synthesis (lipogenesis) through the activation of the transcription factor SREBP-1c can prevent lethality as well as severe lipotoxicity caused by a combined deficiency in lipogenesis and beta-oxidation. Altogether, this study reveals that optimizing lipid signals generated by lipogenesis through SREBP-1c can help redirect fatty acids toward beneficial actions, by buffering lipotoxic lipid intermediates even in the setting of lipid overload.

PMID- 29174380 TI - Effect of heme oxygenase-1 on the protection of ischemia reperfusion injury of bile duct in rats after liver transplantation. AB - OBJECTIVE: To investigate the effect of heme oxygenase-1 (HO-1) on the ischemic reperfusion injury (IRI) of bile duct in rat models after liver transplantation. METHODS: 320 SD rats were equally and randomly divided into 5 groups, which were group A receiving injection of 3*108/pfu/ml adenovirus (adv), group B with donor receiving Adv-HO-1 and recipient receiving Adv-HO-1-siRNA, group C with donor and recipient both receiving Adv-HO-1, group D with donor receiving Adv-HO-1-siRNA and recipient receiving Adv-HO-1, and group E with donor and recipient both receiving Adv-HO-1-siRNA at 24h before liver transplantation. Donor liver was stored in UW liquid at 4 degrees C followed by measuring HO-1 level by western blot before transplantation. On d1, d3, d7 and d14, serum and liver was isolated for analysis of liver function, inflammatory cell infiltration by H&E staining, ultrastructure of liver by transmission electron microscopy as well as the expression of HO-1, Bsep, Mrp2 and Ntcp by western blot. RESULTS: Compared with group D and E, group B and C displayed improved liver function as demonstrated by lower level of ALT, AST, LDH, TBIL, ALP and GGT, increased secretion of TBA and PL as well as expression of transporter proteins (Bsep, Mrp2 and Ntcp), reduced inflammatory cells infiltration and liver injury. CONCLUSION: Our study demonstrated that overexpression of HO-1 in donor liver can ameliorate the damage to bile duct and liver, and improved liver function, suggesting HO-1 might be a new therapeutic target in the treatment of IRI after liver transplantation. PMID- 29174381 TI - Anti-neuroinflammatory effect of 6,8,1'-tri-O-methylaverantin, a metabolite from a marine-derived fungal strain Aspergillus sp., via upregulation of heme oxygenase-1 in lipopolysaccharide-activated microglia. AB - In the course of searching for anti-neuroinflammatory metabolites from marine derived fungi, three fungal metabolites, 6,8,1'-tri-O-methylaverantin, 6,8-di-O methylaverufin, and 5-methoxysterigmatocystin were isolated from a marine-derived fungal strain Aspergillus sp. SF-6796. Among these, 6,8,1'-tri-O-methylaverantin induced the expression of heme oxygenase (HO)-1 protein in BV2 microglial cells. The induction of HO-1 protein was mediated by the activation of nuclear transcription factor erythroid-2 related factor 2 (Nrf2), and was regulated by the p38 mitogen-activated protein kinase and phosphatidylinositol 3 kinase/protein kinase B signaling pathways. Furthermore, 6,8,1'-tri-O methylaverantin suppressed the overproduction of pro-inflammatory mediators, such as nitric oxide, prostaglandin E2, inducible nitric oxide synthase, and cyclooxygenase-2 in lipopolysaccharide (LPS)-stimulated BV2 microglial cells. These anti-neuroinflammatory effects were mediated through the negative regulation of the nuclear factor kappa B pathway, repressing the phosphorylation and degradation of inhibitor kappa B-alpha, translocation into the nucleus of p65/p50 heterodimer, and DNA-binding activity of p65 subunit. The anti neuroinflammatory effect of 6,8,1'-tri-O-methylaverantin was partially blocked by a selective HO-1 inhibitor, suggesting that its anti-neuroinflammatory effect is at least partly mediated by HO-1 induction. In this study, 6,8,1'-tri-O methylaverantin also induced HO-1 protein expression in primary microglial cells, and this correlated with anti-neuroinflammatory effects observed in LPS stimulated primary microglial cells. In conclusion, 6,8,1'-tri-O-methylaverantin represents a potential candidate for use in the development of therapeutic agents for the regulation of neuroinflammation in neurodegenerative diseases. PMID- 29174382 TI - Methylated flavonoids as anti-seizure agents: Naringenin 4',7-dimethyl ether attenuates epileptic seizures in zebrafish and mouse models. AB - Epilepsy is a neurological disease that affects more than 70 million people worldwide and is characterized by the presence of spontaneous unprovoked recurrent seizures. Existing anti-seizure drugs (ASDs) have side effects and fail to control seizures in 30% of patients due to drug resistance. Hence, safer and more efficacious drugs are sorely needed. Flavonoids are polyphenolic structures naturally present in most plants and consumed daily with no adverse effects reported. These structures have shown activity in several seizure and epilepsy animal models through allosteric modulation of GABAA receptors, but also via potent anti-inflammatory action in the brain. As such, dietary flavonoids offer an interesting source for ASD and anti-epileptogenic drug (AED) discovery, but their pharmaceutical potential is often hampered by metabolic instability and low oral bioavailability. It has been argued that their drug-likeness can be improved via methylation of the free hydroxyl groups, thereby dramatically enhancing metabolic stability and membrane transport, facilitating absorption and highly increasing bioavailability. Since no scientific data is available regarding the use of methylated flavonoids in the fight against epilepsy, we studied naringenin (NRG), kaempferol (KFL), and three methylated derivatives, i.e., naringenin 7-O methyl ether (NRG-M), naringenin 4',7-dimethyl ether (NRG-DM), and kaempferide (4'-O-methyl kaempferol) (KFD) in the zebrafish pentylenetetrazole (PTZ) seizure model. We demonstrate that the methylated flavanones NRG-DM and NRG-M are highly effective against PTZ-induced seizures in larval zebrafish, whereas NRG and the flavonols KFL and KFD possess only a limited activity. Moreover, we show that NRG DM is active in two standard acute mouse seizure models, i.e., the timed i.v. PTZ seizure model and the 6-Hz psychomotor seizure model. Based on these results, NRG DM is proposed as a lead compound that is worth further investigation for the treatment of generalized seizures and drug-resistant focal seizures. Our data therefore highlights the potential of methylated flavonoids in the search for new and improved ASDs. PMID- 29174383 TI - Intracerebroventricular streptozotocin impairs adult neurogenesis and cognitive functions via regulating neuroinflammation and insulin signaling in adult rats. AB - Neurogenesis is a complex process involved in memory formation and is known to be altered in Alzheimer's disease (AD). Neuroinflammation and insulin signaling dysfunction, key players during intracerebroventricular Streptozotocin (ICV-STZ) induced dementia variedly affects neurogenesis. The aim of this work was to study the variation in neurogenic process associated with AD in ICV STZ induced dementia. Adult male Sprague Dawley rats weighing 180-200 g were given two different doses of ICV STZ (3 mg/kg on Day 1 and 3, & 1 mg/kg on Day 1) in two different experimental setup. Memory functions were assessed by Morris Water Maze. Immunofluorescence and western blotting was done to study the variation in neurogenesis, amyloid and tau pathology, neuroinflammation and insulin signaling. ICV STZ 6 mg/kg (3 mg/kg twice on Day 1 and 3 of 21 days study) caused impairment in learning and memory and severe atrophy of the neurogenic areas. Modified dose of ICV STZ (1 mg/kg once on Day 1) caused a significant decline in neurogenesis in subventricular zone (SVZ) and dentate gyrus (DG) as indicated by decrease in the number of (5-Bromo-2'-deoxyuridine) BrdU+ Nestin+ cells, Doublecortin (DCX+) cells and BrdU+ NeuN+ cells after day 11 and 18 of ICV STZ injection. However, impairment in learning and memory was observed only during 18 days study post ICV STZ injection (1 mg/kg on Day 1). Up regulation of proteins of amyloid and tau pathology (Amyloid precursor protein (APP), beta site amyloid precursor protein cleaving enzyme 1 (BACE1) & p-Tau Ser 396) was observed at this time point with no significant change in amyloid beta42 (Abeta42) expression. Enhanced neuroinflammation (increased Glial fibrillary acidic protein (GFAP) & nuclear factor kappa-light-chain-enhancer of activated B cells (NFkappaB)) and diminished insulin signaling was also observed in our study in both neurogenic areas, however the extent to which they may have negative impact on neurogenes is yet to be explored. PMID- 29174384 TI - Reduction of MRI signal distortion from titanium intracavitary brachytherapy applicator by optimizing pulse sequence parameters. AB - PURPOSE: To demonstrate that optimized pulse sequence parameters for a T2 weighted (T2w) fast spin echo acquisition reduced artifacts from a titanium brachytherapy applicator compared to conventional sequence parameters. METHODS AND MATERIALS: Following Institutional Review Board approval and informed consent, seven patients were successfully imaged with both standard sagittal T2w fast spin echo parameters (voxel size of 0.98 * 0.78 * 4.0 mm3; readout bandwidth of 200 Hz/px; repetition time of 2800 ms; echo time of 91 ms; echo train length of 15; 36 slices; and imaging time of 3:16 min) and an additional optimized T2w sequence (voxel size of 0.98 * 0.98 * 4.0 mm3; readout bandwidth of 500 Hz/px; repetition time of 3610 ms; echo time of 91 ms; echo train length of 25; 18-36 slices; and imaging time of 1:15-2:30 min), which had demonstrated artifact reduction in prior phantom work. Visualized intracavitary tandem was hand segmented by two of the authors. Three body imaging radiologists assessed image quality and intraobserver agreement scores were analyzed. RESULTS: The average segmented volume of the intracavitary applicator significantly (p < 0.05) decreased with the experimental pulse sequence parameters as compared to the standard pulse sequence. Comparison of experimental and standard T2w sequence qualitative scores for each reviewer showed no significant differences between the two techniques. CONCLUSIONS: This study demonstrated that pulse sequence parameter optimization can significantly reduce distortion artifact from titanium applicators while maintaining image quality and reasonable imaging times. PMID- 29174385 TI - Dose warping uncertainties for the accumulated rectal wall dose in cervical cancer brachytherapy. AB - PURPOSE: Structure-based deformable image registration (DIR) can be used to calculate accumulated dose volume histogram parameters for cervical cancer brachytherapy (BT). The purpose of this study is to investigate dose warping uncertainties for the accumulated dose to the 2 cm3 receiving the highest dose [Formula: see text] in the rectal wall, using a physically realistic model (PRM) describing rectal wall deformation. METHODS AND MATERIALS: For 10 patients, treated with MRI-guided pulsed dose rate BT (two times 24 * 0.75 Gy, given in two applications BT1 and BT2), the planning images were registered with structure based DIR. The resulting transformation vectors were used to accumulate the total rectum dose from BT. To investigate the dose warping uncertainty, a PRM describing rectal deformation was used. For point pairs on rectumBT1 and rectumBT2 that were at the same location according to the PRM, the dose for BT1 and BT2 was added (DPRM) and compared to the DIR-accumulated dose (DDIR) in the BT2 point. The remaining distance after DIR between corresponding point pairs, defined as the residual distance, was calculated. RESULTS: For points within the [Formula: see text] volume, more than 75% was part of the [Formula: see text] volume according to both PRM and DIR. The absolute dose difference was <7.3 GyEQD2, and the median (95th percentile) of the residual distance was 8.7 (22) mm. CONCLUSIONS: DIR corresponded with the PRM for on average 75% of the [Formula: see text] volume. Local absolute dose differences and residual distances were large. Care should therefore be taken with DIR for dose-warping purposes in BT. PMID- 29174386 TI - Expression and cellular localization of double sex and mab-3 related transcription factor 1 in testes of postnatal Small-Tail Han sheep at different developmental stages. AB - : Double sex and mab-3 related transcription factor 1 (Dmrt1), an evolutionarily conserved gene, is a sex-related gene expressed in male gonads, that is involved in the regulation of sex differentiation, testicular development and reproductive function maintenance. Until now, functional studies on the Dmrt1 gene in sheep (Ovis aries) have been lacking. In this study, testis, heart, liver, spleen, lung, kidney and longissimus dorsi muscle tissues were collected from Small-Tail Han sheep at 0, 2, 5, 12 and 24months after birth (mab). Dmrt1 expression and cellular localization were detected in various testicular tissues by quantitative real time PCR (qRT-PCR), western blot and immunohistochemistry methods. The morphological structures of testicular tissues at different developmental stages were observed by hematoxylin & eosin (HE) staining. The Dmrt1 mRNA expression levels in 12 and 24 mab sheep were significantly higher than those in 0 and 2 mab sheep (P<0.05), and Dmrt1 protein expression showed a similar trend. The qRT-PCR results in various tissues at 12 mab showed that Dmrt1 mRNA was predominantly expressed in testes. Immunohistochemical staining in testes at different developmental stages showed that Dmrt1 protein immunoreactive responses were mainly localized in Sertoli cells and gonocytes at 0, 2 and 5 mab, while they were localized in spermatocytes, sperm cells and some spermatogonia and Sertoli cells at 12 and 24 mab. We speculate that the Dmrt1 gene plays a vital role in postnatal sheep spermatogenesis, perhaps by regulating the maturation and functional maintenance of Sertoli cells, the proliferation and differentiation of gonocytes in prepubertal sheep testes, and the mitosis and meiosis of germ cells in adult sheep, but the specific mechanisms underlying these phenomena must be further studied and verified. ABBREVIATIONS: PMID- 29174387 TI - Role of tumor necrosis factor-alpha in epithelial-to-mesenchymal transition in transplanted kidney cells in recipients with chronic allograft dysfunction. AB - BACKGROUND: Chronic allograft dysfunction (CAD) is characterized by allograft kidney interstitial fibrosis, the underlying mechanism of which is unclear. Our aim was to elucidate the role and mechanism of TNF-alpha-induced epithelial-to mesenchymal transition (EMT) in transplant kidney tubular interstitial fibrosis. METHODS: Human kidney tissues from normal volunteers and CAD patients were assessed using periodic acid-Schiff, Masson trichrome and immunohistochemical staining. mRNA and protein expression of E-cadherin, alpha-smooth muscle actin (SMA) and fibronectin(FN) in renal proximal tubule epithelial (HK-2) cells after treatment with TNF-alpha under different conditions were assessed using western blot and qRT-PCR analysis. Cell motility and migration were assessed using wound healing and transwell assays. Expression of Smurf2 and TNF-alpha-signaling pathway-related proteins in HK-2 cells treated with TNF-alpha was detected by western blotting. E-cadherin and alpha-SMA expression was also assessed in Smurf2 plasmid-transfected or Smurf2 siRNA-treated HK-2 cells. RESULTS: The expression of TNF-alpha, Smurf2, alpha-SMA, and fibronectin was significantly upregulated, while the expression of E-cad was downregulated in the CAD group compared with the normal group. The in vitro results showed that TNF-alpha remarkably upregulated the expression of Smurf2, alpha-SMA and fibronectin and downregulated the expression of E-cadherin in HK-2 cells and enhanced motility and migration in HK-2 cells. Overexpression of Smurf2 could promote the expression of alpha-SMA and inhibit the expression of E-cad, whereas knockdown of Smurf2 expression reversed TNF-alpha-induced upregulation of alpha-SMA and prohibited the reduction of E-cad expression. Furthermore, TNF-alpha-induced Smurf2 expression promoted EMT through the Akt signaling pathway. CONCLUSIONS: TNF-alpha induced EMT via the TNF-alpha/Akt/Smurf2 signaling pathways, and it may play a role in aggravating allograft kidney interstitial fibrosis in CAD patients. PMID- 29174388 TI - Smokers' identity and quit advice in general practice: General practitioners need to focus more on female smokers. AB - OBJECTIVE: We examined smoker and non-smoker self-identities among smokers visiting their general practitioner (GP) for other reasons than smoking cessation counselling. We determined whether identity impacted on patients' appreciation of GP-initiated conversations about smoking and quit advice, and subsequent quit attempts, and examined the role of gender. METHODS: Secondary analyses of a cluster-randomised controlled trial in which baseline and 12-month follow-up data were collected among 527 daily (n=450) and non-daily smokers (n=77). RESULTS: Participants identified more with smoking than non-smoking. Participants with stronger non-smoker self-identities were more often female, appreciated the conversation about smoking more, were more likely to receive quit-advice and to have attempted to quit at 12-month follow-up. Participants with stronger smoker self-identities were also more often female, and appreciated the conversation more. Men with stronger non-smoker self-identities were more often asked about smoking and advised to quit, and appreciated the conversation more than women. CONCLUSION: Non-smoker identity was more important for receiving quit-advice, appreciation, and quit attempts than smoker identity. Future research needs to unravel why female smokers appreciated the conversation less than male smokers. PRACTICE IMPLICATIONS: We suggest to incorporate an identity-component in smoking cessation interventions. GPs should increase their focus on female patients who smoke. PMID- 29174389 TI - Temporal variability in lipoprotein(a) levels in patients enrolled in the placebo arms of IONIS-APO(a)Rx and IONIS-APO(a)-LRx antisense oligonucleotide clinical trials. AB - BACKGROUND: Lipoprotein(a) [Lp(a)] levels are primarily genetically determined, but their natural variability is not well known. OBJECTIVE: The aim of the study was to evaluate the short-term temporal variability in Lp(a) in 3 placebo groups from the IONIS-APO(a)Rx and IONIS-APO(a)-LRx trials. METHODS: The placebo groups comprised 3 studies: Study 1 with 10 subjects with any Lp(a) concentration; Study 2 with 13 subjects with Lp(a) >=75 nmol/L (~30 mg/dL); and Study 3 with 29 patients with Lp(a) >=125 nmol/L (>=~50 mg/dL). Lp(a) was measured in serial blood samples (range 7-12 samples up to 190 days of follow-up) and analyzed as absolute change and mean percent change from baseline. Outliers were defined as having a > +/-25% difference in Lp(a) from baseline at any future time point. RESULTS: No significant temporal differences in mean absolute Lp(a) levels were present in any group. However, among individuals, the mean change in absolute Lp(a) levels at any time point ranged from -16.2 to +7.0 nmol/L in Study 1, -15.8 to +9.8 nmol/L in Study 2, and -60.2 to +16.6 nmol/L in Study 3. The mean percent change from baseline ranged from -9.4% to +21.6% for Study 1, -13.1% to 2.8% for Study 2, and -12.1% to +4.9% in Study 3. A total of 21 of 52 subjects (40.4%) were outliers, with 13 (62%) >25% up and 8 (38%) >25% down. Significant variability was also noted in other lipid parameters, but no outliers were noted with serum albumin. CONCLUSION: In subjects randomized to placebo in Lp(a) lowering trials, modest intra-individual temporal variability of mean Lp(a) levels was present. Significant number of subjects had > +/-25% variation in Lp(a) in at least 1 time point. Although Lp(a) levels are primarily genetically determined, further study is required to define additional factors mediating short-term variability. PMID- 29174390 TI - Direct Aortic Access for Transcatheter Aortic Valve Replacement Using a Self Expanding Device. AB - BACKGROUND: Transcatheter aortic valve replacement (TAVR) using a self-expanding valve has been shown to be superior to an open operation in high-risk patients. Extensive iliofemoral peripheral vascular disease can prohibit femoral access. In these cases, direct aortic (DA) implantation may be a suitable option. METHODS: The current analysis compared outcomes in patients undergoing TAVR with the self expanding CoreValve prosthesis (Medtronic, Minneapolis, MN) by direct aortic (DA) access vs iliofemoral (IF) access. Patients treated in the CoreValve US High Risk and Extreme Risk Pivotal Trials and Continued Access Study were included. Propensity score matching was used to account for differences in baseline characteristics between groups. Clinical outcomes were compared at 30 days and 1 year. RESULTS: We identified 394 matched pairs of IF and DA patients. The all cause mortality rate was significantly higher in the DA group than in the IF group at 30 days (10.9% vs 4.1%, p < 0.001), but this difference was reduced at 1 year (28.1% vs 23.2%, p = 0.063). All-cause mortality or major stroke was significantly higher for DA vs IF access at 30 days (13.5% vs 5.3%, p < 0.001) and at 1 year (30.4% vs 24.2%, p = 0.025). Major/life-threatening bleeding and acute kidney injury were significantly greater in the DA group at 30 days (66.7% vs 35.4% and 19.7% vs 10.0%, respectively, both p < 0.001). CONCLUSIONS: When femoral access is not feasible, DA access allows effective delivery of the valve but incurs an increased risk of death and adverse events, potentially the result of procedural differences. PMID- 29174391 TI - Prediction of Long-Term Survival After Lung Cancer Surgery for Elderly Patients in The Society of Thoracic Surgeons General Thoracic Surgery Database. AB - BACKGROUND: Prior risk models using the STS General Thoracic Surgery database (STS-GTSD) have been limited to 30-day outcomes. We have now linked STS data to Medicare data and sought to create a risk prediction model for long-term mortality after lung cancer resection in patients older than 65 years. METHODS: The STS-GTSD was linked to Medicare data for lung cancer resections from 2002 to 2013 as previously reported. Successful linkage was performed in 29,899 lung cancer resection patients. Cox proportional hazards modeling was used to create a long-term survival model. Variable selection was performed using statistically significant univariate factors and known clinical predictors of outcome. Calibration was assessed by dividing the cohort into deciles of predicted survival and discrimination assessed with a C-statistic corrected for optimism via 1,000 bootstrap replications. RESULTS: Median age was 73 years (interquartile range, 68 to 78 years), and 48% of the patients were male. Of the 29,094 patients with nonmissing pathologic stage, 69% were stage I, 18% stage II, 11% stage III, and 2% stage IV. Procedure performed was lobectomy in 69%, bilobectomy in 3%, pneumonectomy in 3%, segmentectomy in 7%, sleeve lobectomy in 1%, and wedge resection in 17%. Thoracoscopic approach was performed in 47% of resections. The final Cox model reveals that stage and age are the strongest predictors of long term survival. Even after controlling for stage, wedge resection, segmentectomy, bilobectomy, and pneumonectomy are all associated with increased hazard of death in comparison with lobectomy. Thoracoscopic approach is associated with improved long-term survival in comparison with thoracotomy. Other modifiable predictive factors include smoking and low body mass index. Calibration of the model demonstrates excellent performance across all survival deciles and a C-statistic of 0.694. CONCLUSIONS: The STS-GTSD-Medicare long-term risk model includes several novel factors associated with mortality. Although medical factors predict long-term survival, age and stage are the strong predictors. Despite this, procedure choice and thoracoscopic/open approach are potentially modifiable predictors of long-term survival after lung cancer resection.

AB - PURPOSE: This descriptive study provides a summary of the binocular anomalies seen in elementary school children identified with reading problems. METHODS: A retrospective chart review of all children identified with reading problems and seen by the University of Waterloo, Optometry Clinic, from September 2012 to June 2013. RESULTS: Files of 121 children (mean age 8.6 years, range 6-14 years) were reviewed. No significant refractive error was found in 81% of children. Five and 8 children were identified as strabismic at distance and near respectively. Phoria test revealed 90% and 65% of patients had normal distance and near phoria. Near point of convergencia (NPC) was <5cm in 68% of children, and 77% had stereoacuity of <=40seconds of arc. More than 50% of the children had normal fusional vergence ranges except for near positive fusional vergencce (base out) break (46%). Tests for accommodation showed 91% of children were normal for binocular facility, and approximately 70% of children had an expected accuracy of accommodation. CONCLUSION: Findings indicate that some children with an identified reading problem also present with abnormal binocular test results compared to published normal values. Further investigation should be performed to investigate the relationship between binocular vision function and reading performance. PMID- 29174395 TI - Normalization of mass spectrometry data (NOMAD). AB - iTRAQ and TMT reagent-based mass spectrometry (MS) are commonly used technologies for quantitative proteomics in biological samples. Such studies are often performed over multiple MS runs, potentially resulting in introduction of MS run bias that could affect downstream analysis. Such MS data have therefore commonly been normalized using a reference sample which is included in each MS run. We show, however, that reference normalization does not effectively remove systematic MS run bias. A linear model approach was previously proposed to improve on the reference normalization approach but does not computationally scale to larger data sets. Here we describe the NOMAD (normalization of mass spectrometry data) R package which implements a computationally efficient ANOVA normalization approach with protein assembly functionality. NOMAD provides the same advantages as the linear regression solution but is more computationally efficient which allows superior scaling to larger sample sizes. Moreover, NOMAD effectively removes bias which improves valid across MS run comparisons. PMID- 29174396 TI - PLCgamma1: Potential arbitrator of cancer progression. AB - Phospholipase C (PLC) is an essential mediator of cellular signaling. PLC regulates multiple cellular processes by generating bioactive molecules such as inositol-1,4,5-triphosphate (IP3) and diacylglycerol (DAG). These products propagate and regulate cellular signaling via calcium (Ca2+) mobilization and activation of protein kinase C (PKC), other kinases, and ion channels. PLCgamma1, one of the primary subtypes of PLC, is directly activated by membrane receptors, including receptor tyrosine kinases (RTKs), and adhesion receptors such as integrin. PLCgamma1 mediates signaling through direct interactions with other signaling molecules via SH domains, as well as its lipase activity. PLCgamma1 is frequently enriched and mutated in various cancers, and is involved in the processes of tumorigenesis, including proliferation, migration, and invasion. Although many studies have suggested that PLCgamma functions in cell mobility rather than proliferation in cancer, questions remain as to whether PLCgamma regulates mitogenesis and whether PLCgamma promotes or inhibits proliferation. Moreover, how PLCgamma regulates cancer-associated cellular processes and the interplay among other proteins involved in cancer progression have yet to be fully elucidated. In this review, we discuss the current understanding of the role of PLCgamma1 in cancer mobility and proliferation. PMID- 29174397 TI - [Case-non case studies: Principles, methods, bias and interpretation]. AB - Case-non case studies belongs to the methods assessing drug safety by analyzing the disproportionality of notifications of adverse drug reactions in pharmacovigilance databases. Used for the first time in the 1980s, the last few decades have seen a significant increase in the use of this design. The principle of the case-non case study is to compare drug exposure in cases of a studied adverse reaction with that of cases of other reported adverse reactions and called "non cases". Results are presented in the form of a reporting odds ratio (ROR), the interpretation of which makes it possible to identify drug safety signals. This article describes the principle of the case-non case study, the method of calculating the ROR and its confidence interval, the different modalities of analysis and how to interpret its results with regard to the advantages and limitations of this design. PMID- 29174398 TI - Assessment of the transmembrane domain structures in GPCR Dock 2013 models. AB - The community-wide blind prediction of G-protein coupled receptor (GPCR) structures and ligand docking has been conducted three times and the quality of the models was primarily assessed by the accuracy of ligand binding modes. The seven transmembrane (TM) helices of the receptors were taken as a whole; thus the model quality within the 7TM domains has not been evaluated. Here we evaluate the 7TM domain structures in the models submitted for the last round of prediction - GPCR Dock 2013. Applying the 7 * 7 RMSD matrix analysis described in our prior work, we show that the models vary widely in prediction accuracy of the 7TM structures, exhibiting diverse structural differences from the targets. For the prediction of the 5-hydroxytryptamine receptors, the top 7TM models are rather close to the targets, which however are not ranked top by ligand-docking. On the other hand, notable deviations of the TMs are found in in the previously identified top docking models that closely resemble other receptors. We further reveal reasons of success and failure in ligand docking for the models. This current assessment not only complements the previous assessment, but also provides important insights into the current status of GPCR modeling and ligand docking. PMID- 29174399 TI - Better together: Contrasting the hypotheses explaining the one-target advantage. AB - Movement times are significantly shorter when moving from a start position to a single target, compared to when one has to continue onto a second target (i.e., the one-target advantage [OTA]). To explain this movement time difference, both the movement integration and the movement constraint hypotheses have been proposed. Although both hypotheses have been found to have explanatory power as to why the OTA exists, the support for each has been somewhat equivocal. The current review evaluated the relative support in the literature for these two hypotheses. Ultimately, preferential support for each theoretical explanation was found to be related to the higher indices of difficulty (IDs: Fitts, 1954) employed. That is, studies that included higher IDs (i.e., 6-8 bits) were more likely to provide more support for the movement constraint hypothesis, whereas studies employing lower IDs (i.e., 1-4 bits) were more likely to provide more support for the movement integration hypothesis. When the IDs employed were relatively intermediate (i.e., 5 bits), both hypotheses were mostly supported. Thus, task difficulty is crucial when determining which hypothesis better explains the planning and control of sequential goal-directed movements. Critically, the OTA most likely always involves integration but may also involve constraining if the accuracy demands are sufficiently high. PMID- 29174400 TI - Self-assembled monolayer-based immunoassays for okadaic acid detection in seawater as monitoring tools. AB - Rapid and cost-effective methods to monitor the presence of diarrhetic shellfish poisoning (DSP) toxins in seawater samples in an easy and reliable manner are required to protect human health and avoid economic losses to shellfish industry. Immunoassays for the detection of okadaic acid (OA) and dinophysistoxin-1 and dinophysistoxin-2 are developed by immobilising OA on self-assembled monothiols or dithiols in an ordered and oriented way, providing an effective limit of detection of ~1 ng OA equiv./mL seawater. The immunoassays are applied to the analysis of the particulate fraction of seawater samples from two Catalan harbours (NW Mediterranean) and samples collected periodically from the Galician Rias (E Atlantic), as well as a reference mussel sample. Results are in agreement with LC-MS/MS and the certified values. OA concentration in seawater correlates with Dinophysis cell abundance, with a 1-2 weeks lag. The immunoassays provide powerful high-throughput analytical methods potentially applicable as alternative monitoring tools. PMID- 29174401 TI - The Gut Microbiota Facilitates Drifts in the Genetic Diversity and Infectivity of Bacterial Viruses. AB - The intestinal microbiota and human health are intimately linked, but interactions between bacteria and bacteriophages in the context of the mammalian intestine remain largely unexplored. We used comparative population genomics to study a tripartite network consisting of a virulent bacteriophage, its bacterial host, and a phage-insensitive bacterial strain both in vitro and within the murine gut. The bacteriophage adapted to infect the insensitive strain when the three partners co-existed in the gut of conventional mice, but not in dixenic mice or in planktonic cultures. The molecular changes associated with modifications in the bacteriophage host spectrum included single amino acid substitutions and an unusual homologous intragenomic recombination event within the genome of the bacteriophage. An intermediate bacterial host isolated from the murine microbiota mediated bacteriophage adaptation. Our data indicate that by offering access to new hosts, the microbiota shifts the genetic diversity of bacteriophages, thereby promoting long-term persistence of bacteriophage populations. PMID- 29174402 TI - Commensal Fungi Recapitulate the Protective Benefits of Intestinal Bacteria. AB - Commensal intestinal microbes are collectively beneficial in preventing local tissue injury and augmenting systemic antimicrobial immunity. However, given the near-exclusive focus on bacterial species in establishing these protective benefits, the contributions of other types of commensal microbes remain poorly defined. Here, we show that commensal fungi can functionally replace intestinal bacteria by conferring protection against injury to mucosal tissues and positively calibrating the responsiveness of circulating immune cells. Susceptibility to colitis and influenza A virus infection occurring upon commensal bacteria eradication is efficiently overturned by mono-colonization with either Candida albicans or Saccharomyces cerevisiae. The protective benefits of commensal fungi are mediated by mannans, a highly conserved component of fungal cell walls, since intestinal stimulation with this moiety alone overrides disease susceptibility in mice depleted of commensal bacteria. Thus, commensal enteric fungi safeguard local and systemic immunity by providing tonic microbial stimulation that can functionally replace intestinal bacteria. PMID- 29174404 TI - Does Time to Surgery Affect Outcomes for Periprosthetic Femur Fractures? AB - BACKGROUND: Periprosthetic femur fractures around total hip (THA) and total knee (TKA) arthroplasties are difficult complications to manage. With native hip fractures, delay to fixation has been correlated with an increase in postoperative mortality. The effect of time to definitive fixation of periprosthetic femur fractures around THA and TKA is not well established. The aim of our study is to evaluate the effect of time to definitive fixation on postoperative length of stay and mortality for patients with periprosthetic femur fractures around THA and TKA. METHODS: A review of 2537 arthroplasty patient charts yielded 235 patients who were diagnosed with a periprosthetic femur fracture at our institution from 2005 to 2014. Time to surgical management, length of stay, demographics, referral status, fracture classification, and fixation modality along with mortality was recorded for all patients. RESULTS: One hundred eighty patients met study inclusion (111 THAs, 69 TKAs). Average age was 79.2 years and 72.2% were female. The average time from admission to definitive fixation was 96.5 hours with 31.1% of patients having surgery within 48 hours after presenting to hospital. Postoperative length of stay and mortality were not affected by time to definitive fixation greater than 48 hours for either of the periprosthetic TKA or THA patient cohorts. Postoperative mortality within 1 year was 5.5% for all patients (6.3% THA, 4.3% TKA). CONCLUSION: The timing of fixation of periprosthetic femur fractures does not appear to affect postoperative length of stay or mortality within 1 year. PMID- 29174403 TI - A Bacterial Type III Effector Targets the Master Regulator of Salicylic Acid Signaling, NPR1, to Subvert Plant Immunity. AB - Most plant bacterial pathogens rely on type III effectors to cause diseases. Although it is well known that the plant hormone salicylic acid (SA) plays an essential role in defense, whether the master regulator of SA signaling, NPR1, is targeted by any plant pathogen effectors is unknown. SA facilitates the reduction of cytosolic NPR1 oligomers into monomers, which enter the nucleus and function as transcriptional coactivators of plant defense genes. We show that SA promotes the interaction between the Pseudomonas syringae type III effector AvrPtoB and NPR1. In the presence of SA, AvrPtoB mediates the degradation of NPR1 via the host 26S proteasome in a manner dependent on AvrPtoB's E3 ligase activity. Intriguingly, we found that NPR1 plays an important role in MAMP-triggered immunity (MTI), inducing the expression of MTI marker genes. Thus, this work uncovers a strategy in which AvrPtoB targets NPR1 and represses NPR1-dependent SA signaling, thereby subverting plant innate immunity. PMID- 29174405 TI - Mixing of Head-Stem Components in Total Hip Arthroplasty. AB - BACKGROUND: Implant manufacturers proclaim that the tapers of modular total hip arthroplasty are not standardized and can vary from manufacturer to manufacturer. That is why the combination of various components from different manufacturers ("Mix and Match") is not permitted. In this study, different taper combinations were investigated experimentally to assess the effect of "Mix and Match" regarding the taper connection strength. METHODS: Torque-off tests using hip stems and metal femoral heads from 6 different implant manufacturers were performed. First the components were tested as intended and afterwards the stems were combined with metal heads from other manufacturers. RESULTS: There was no significant difference in taper connection strength when stems from the manufacturers Link, Smith & Nephew, and Zimmer were combined with heads from other manufacturers. The Biomet stems showed a significantly reduced taper connection strength if femoral heads of Aesculap, DePuy, or Smith & Nephew were used. On the contrary, the DePuy stems in combination with the originally intended femoral heads showed a significantly lower taper connection strength compared to the use of heads from Link, Biomet, and Zimmer. The same was observed for the Aesculap stems in combination with Zimmer heads. CONCLUSION: The results of this study suggest that mixing components from different manufacturers may affect the taper connection strength and could reduce the stability. As safety should be a high priority in patient treatment, any potential risks should be avoided. Therefore, mixing and matching of heads and femoral stems from different manufacturers cannot be recommended. PMID- 29174406 TI - Total Hip Arthroplasty in Patients With Previous Lumbar Fusion Surgery: Are There More Dislocations and Revisions? AB - BACKGROUND: The purpose of this study was to determine whether the risk of dislocation and/or revision following THA is increased in patients with a history of prior lumbar fusion given the alterations in dynamic pelvic motion following LSF. METHODS: A total of 62,387 patients (5% Medicare part B claims database) were identified from 1997 to 2014 with primary THA. From this group, 1809 patients (2.9%) were stratified to identify those with prior lumbar fusion within 5 years of primary THA to compare risk of dislocation and revision with those without lumbar fusion. Multivariate cox regression analysis was performed adjusting for age, socioeconomic status, race, census, region, gender, Charlson score, preexisting conditions, and type of fusion. RESULTS: Between years 2002 and 2014, there was a 293% increase in the number of patients with prior lumbar fusion undergoing THA. Prevalence of hip dislocation in patients with lumbar fusion before THA was 7.4% compared to 4.8% without fusion, P < .001. There was an 80% increase in dislocation in the fusion group at 6 months, 71% at 1 year, and 60% at 2 years. There was a 48% increased risk of failure leading to revision hip surgery in patients with fusion at 6 months, 41% at 1 year, and 47% at 2 years. Dislocation was the most common mode of failure leading to revision in both the fusion group (20.8%) and the nonfusion group (16%). CONCLUSION: Results of this study demonstrate that lumbar fusion before THA is an independent risk factor for dislocation leading to increased risk of revision THA. PMID- 29174407 TI - Hypothyroidism Increases 90-Day Complications and Costs Following Primary Total Knee Arthroplasty. AB - BACKGROUND: Thyroid disease is common and often remains undetected in the US population. Thyroid hormone has an array of metabolic, immunologic, and musculoskeletal functions crucial to well-being. The influence of thyroid disease on perioperative outcomes following primary total knee arthroplasty (TKA) is poorly understood. We hypothesized that hypothyroidism was associated with a higher risk of postoperative complications and 90-day costs following primary TKA. METHODS: The Medicare standard analytical files were queried using International Classification of Disease codes between 2005 and 2014 to identify patients undergoing primary TKA. Patients with a diagnosis of hypothyroidism were matched by age and gender on a 1:1 ratio. Ninety-day postoperative complication rates, day of surgery, and 90-day global period charges and reimbursements were compared between matched cohorts. RESULTS: A total of 2,369,594 primary TKAs were identified between 2005 and 2014. After age and gender matching, each cohort consisted of 98,555 patients. Hypothyroidism was associated with greater odds of postoperative complications compared to matched controls (odds ratio 1.367, 95% confidence interval 1.322-1.413). The 90-day incidence of multiple postoperative medical and surgical complications, including periprosthetic joint infection, was higher among patients with hypothyroidism. Day of surgery and 90-day episode of care costs were significantly higher in the hypothyroidism cohort. CONCLUSION: This study demonstrated an increased risk of multiple postoperative complications and higher costs among patients with hypothyroidism following primary TKA. Surgeons should counsel patients on these findings and seek preoperative optimization strategies to reduce these risks and lower costs in this patient population. PMID- 29174408 TI - Survivorship and Outcomes in Patients With Multiple Sclerosis Undergoing Total Joint Arthroplasty. AB - BACKGROUND: Patients with multiple sclerosis (MS) frequently require total joint arthroplasty (TJA). The outcomes of TJA in patients with MS, who are frequently on immunomodulatory medications and physically deconditioned, remain largely unknown. The aim of this study is to elucidate the survivorship and reasons for failure in this patient population. METHODS: A single-institution retrospective review of 108 TJAs (46 knees and 62 hips) was performed from 2000 to 2016. An electronic chart query based on MS medications and International Classification of Diseases, Ninth Revision codes was used to identify this population followed by a manual review to confirm the diagnosis. Outcomes were then assessed using revision for any reason as the primary end point. Functional outcomes were assessed using Short Form 12 scores. Survivorship curves were generated using the Kaplan-Meier method. RESULTS: At an average follow-up of 6.2 years, 19.4% (21/108) of patients required a revision surgery. Instability (5.6%, P = .0278) and periprosthetic joint infection (4.6%, P = .0757) were among the most common reasons for revision. The overall survivorship of TJA at years 2, 5, and 7, respectively, was 96.5% (95% confidence interval [CI], 92.6-100), 86.3% (95% CI, 77.7-94.5), and 75.3% (95% CI, 63.5-87.0). Functional score improvement was less in MS cohort than patients without MS. CONCLUSION: Patients with MS are at increased risk of complications, particularly instability and periprosthetic joint infection. Despite this increased risk of complications, patients with MS can demonstrate improved functional outcomes, but not as much as patients without MS. Patients with MS should be counseled appropriately before undergoing TJA. PMID- 29174409 TI - Operating Room Traffic Increases Aerosolized Particles and Compromises the Air Quality: A Simulated Study. AB - BACKGROUND: Strategies to prevent bacterial fallout and reduce particle count in the operating room (OR) are key components of preventing periprosthetic joint infection. Although OR traffic control is an important factor, a quantitative study has not been performed to investigate the influence of personnel and door opening on OR air quality. This simulated study aimed to examine the influence of these 2 factors on particle density in OR with and without the laminar air flow (LAF). METHODS: Both experiments took place within an empty OR of an arthroplasty unit equipped with an LAF system. First, the number of particles in the air was counted using a particle counting apparatus while 9 persons entered the room, one every 15 minutes. Second, the door was opened and closed starting with zero door openings per minute and increasing to 4 in 15-minute increments. Both experiments were performed once with the LAF turned on and once without. RESULTS: The number of personnel in the OR and the number of door openings per minute correlate with the density of particles. Both relationships were significantly reduced by turning the LAF on (correlation coefficients <0.4). With the LAF being turned on, the particle density per person decreased from 211.19 to 18.19 particles/ft3 (P < .001) and the particle density per rate of door openings declined from 117.80 to 1.90 particles/ft3 (P = .017). CONCLUSION: This study confirms that personnel and door opening are a major source of particles in the OR air. Controlling traffic is critical for reduction of particles and is likely to be a key preventative strategy in reducing periprosthetic joint infection. LAF is protective against the negative influence of number of people and door openings. PMID- 29174410 TI - A government policy on full-time nursing employment in Ontario, Canada: An evaluation. AB - PURPOSE: To evaluate the impact of a government full-time employment policy targeting new graduate nurses in the province of Ontario, Canada, by comparing participants with non-participants. METHODS: The Policy Impact on Nurse Employment (PINEP) survey was administered in 2014 to nurses who graduated between 2007 and 2012. Backward multiple logistic regression analysis was conducted to determine the effect of participation in the policy on key outcomes: full-time employment, retention and perceptions of clinical proficiency. RESULTS: A total of 2369 nurses responded to the survey. Policy participants were 1.5 times more likely to be employed full-time and 2.3 times more likely to be retained in their initial position at the time of survey compared to non participants. Participants also perceived their clinical proficiency to be higher. CONCLUSIONS: The evidence is converging around the importance of providing full-time employment to nurses to sustain the workforce, increase clinical proficiency and improve patient outcomes. In Ontario, the government created a policy to stimulate full-time employment for nurses. Results demonstrate that nursing employment has become more stable. Yet more needs to be done particularly in relation to the precarious employment trend. PMID- 29174412 TI - How do we manage overdiagnosis/overtreatment in breast screening? AB - Overdiagnosis is the inevitable flip side of early detection resulting in unnecessary labelling of well women with a diagnosis of cancer and possible unnecessary treatment. Overdiagnosis occurs because breast cancers have different rates of growth and slow-growing cancers are preferentially detected by screening. Some of these slow-growing screen-detected cancers may never have been clinically apparent during an individual's lifetime. Evaluating the benefits and risks of screening are complex, but this has been performed for the UK population by an independent review led by Professor Marmot. It might be possible to limit overdiagnosis by identifying women with "low-risk disease" earlier, either at the point of screening when additional investigations could be delayed (possibly for ever) so that they are not subjected to additional diagnostic tests, or at the point of diagnosis. Both these options would require major re-education of clinicians and the public who would need to accept that screening is "deliberately ignoring a cancer". There is a long surgical history of reducing the burden of treatment, which continues today with trials of management of the axilla and reducing or even omitting radiotherapy for low-risk disease. The Low Risk Ductal Carcinoma In Situ trial (LORIS) has started to identify a group of breast cancer patients who could avoid surgery and be offered active monitoring. We need to consider planning a similar trial for low-risk invasive breast cancer.

PMID- 29174413 TI - MRI-measured myocardial iron load in patients with severe diabetic heart failure. AB - AIM: To investigate whether a correlation exists between abnormal myocardial iron status and cardiac lipid deposition as well as other biomarkers in patients with diabetic heart failure (DHF). MATERIALS AND METHODS: Seventeen volunteers (Group 1), 26 patients with non-severe DHF (Group 2), and 25 patients with severe DHF (Group 3) were recruited for this study. Myocardial middle-section T2* mapping and septal 1H magnetic resonance spectroscopy (1H-MRS) were performed using a 3 T magnetic resonance imaging (MRI) machine to assess the iron status and lipid deposition individually. Fasting venous blood was used to examine serum biomarkers. RESULTS: Cardiac T2* (ms) of the three groups were 22.8+/-2.1, 21.7+/ 1.8, and 18.6+/-1.3, respectively. The value of Group 3 was significantly lower than that of the other two groups (p<0.001). Myocardial triglyceride (%) levels differed among the three groups (Group 1, 0.53+/-0.13; Group 2, 1.11+/-0.29; Group 3, 1.47+/-0.12; p<0.001). Cardiac T2* was inversely correlated with both cardiac triglycerides and left ventricular ejection fraction (LVEF) in overall participants (Groups 1-3) or Group 3 (each p<0.001). CONCLUSIONS: Abnormal myocardial iron status was found in patients with severe diabetic heart failure. Myocardial lipotoxicity may be responsible for this process.

AB - Sleep disordered breathing (SDB) and obstructive sleep apnea (OSA) during pregnancy are growing health concerns because these conditions are associated with adverse outcomes for newborn infants. SDB/OSA during pregnancy exposes the mother and the fetus to intermittent hypoxia. Direct exposure of adults and neonates to IH causes neuroinflammation and neuronal apoptosis, and exposure to IH during gestation (GIH) causes long-term deficits in offspring respiratory function. However, the role of neuroinflammation in CNS respiratory control centers of GIH offspring has not been investigated. Thus, the goal of this hybrid review/research article is to comprehensively review the available literature both in humans and experimental rodent models of SDB in order to highlight key gaps in knowledge. To begin to address some of these gaps, we also include data demonstrating the consequences of GIH on respiratory rhythm generation and neuroinflammation in CNS respiratory control regions. Pregnant rats were exposed to daily intermittent hypoxia during gestation (G10-G21). Neuroinflammation in brainstem and cervical spinal cord was evaluated in P0-P3 pups that were injected with saline or lipopolysaccharide (LPS; 0.1mg/kg, 3h). In CNS respiratory control centers, we found that GIH attenuated the normal CNS immune response to LPS challenge in a gene-, sex-, and CNS region-specific manner. GIH also altered normal respiratory motor responses to LPS in newborn offspring brainstem-spinal cord preparations. These data underscore the need for further study of the long term consequences of maternal SDB on the relationship between inflammation and the respiratory control system, in both neonatal and adult offspring.

AB - Amyloid-beta (Abeta) plays a relevant role in the neurodegenerative process of Alzheimer's disease (AD). The 25-35 peptide of amyloid-beta (Abeta25-35) induces the inflammatory response in brain experimental models. Mucin-type O glycosylation has been associated with inflammation of brain tissues in AD, thus in this work, we aimed at identifying changes in the glycosylation profile generated by the injection of Abeta25-35 into the CA1 of the hippocampus of rats, using histochemistry with lectins. Our results indicate that 100MUM Abeta25-35 induce increased recognition of the Amaranthus leucocarpus lectin (ALL) (specific for Galbeta1,3-GalNAcalpha1,0-Ser/Thr); whereas concanavalin A (Con A) (specific for alpha-Man) showed no differences among treated and control groups of rats. Jacalin and peanut agglutinin (Galbeta1,3GalNAcalpha1,0-Ser/Thr) showed no recognition of brain cells of control or treated rats. After 6-h treatment of the tissue with trypsin or with 200mM GalNAc, the interaction with ALL was inhibited. Immunohistochemistry showed positive anti-NeuN and ALL-recognition of neurons; however, anti-GFAP and anti-CD11b showed no co-localization with ALL. The ALL+ neurons revealed the presence of cytochrome C in the cytosol and active caspase 3 in the cytosol and nucleus. Administration of the interleukin-1 receptor antagonist (IL-1RA) to Abeta25-35-treated rats diminished neuroinflammation and ALL recognition. These results suggest a close relationship among over-expression of mucin-type O-glycosylation, the neuroinflammatory process, and neuronal death. PMID- 29174416 TI - Unrelated donor umbilical cord blood transplant versus unrelated hematopoietic stem cell transplant in patients with acute leukemia: A meta-analysis and systematic review. AB - Acute leukemia is a global disease with a poor prognosis for many patients. While an increasing number of patients with acute leukemia are being treated with unrelated hematopoietic stem cell transplants (HSCT) or umbilical cord blood transplants (UCBT), recent comparative reports of these 2 procedures are lacking. Therefore, we conducted a meta-analysis of the safety and efficacy of unrelated HSCT and unrelated single-unit UCBT for the treatment of pediatric and adult patients with acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML). The primary outcomes were the rates of relapse, overall survival (OS), progression-free survival (PFS), and days to neutrophil and platelet recovery. Pooled effects (odds ratios [OR] or difference in means) were determined with either random- or fixed-effects models. Our meta-analysis included 9 studies that enrolled 6762 patients (UCBT: n=2026; HSCT: n=4736). The risk of relapse for patients undergoing UCBT was similar to that of patients who received an HSCT (OR=1.030; 95%CI, 0.767 to 1.383, P=0.847). We also found no difference between HSCT and UCBT for OS (pooled OR=1.417; 95%CI, 0.936 to 2.146; P=0.100) or PFS (OR=1.165; 95%CI, 0.996 to 1.362; P=0.056). However, neutrophil and platelet recovery periods were both shorter after HSCT than after UCBT (neutrophil recovery: difference in means=-3.420, 95% CI: -5.491 to -1.349, P=0.001; platelet recovery: difference in means -20.350, 95% CI: -33.656 to -7.044, P=0.003). Collectively, our data provide strong evidence to support increased use of cord blood transplants for both adults and children with acute leukemia. PMID- 29174417 TI - Phenylpropanoids isolated from Piper sarmentosum Roxb. induce apoptosis in breast cancer cells through reactive oxygen species and mitochondrial-dependent pathways. AB - The aim of the present study is to isolate bioactive compounds from the roots of Piper sarmentosum and examine the mechanism of action using human breast cancer cell line (MDA-MB-231). Bioassay guided-fractionation of methanolic extract led to the isolation of asaricin (1) and isoasarone (2). Asaricin (1) and isoasarone (2) had significant cytotoxicity towards MDA-MB-231. MCF-10A (human normal breast epithelial cells) cells are less sensitive than MDA-MB-231, but they respond to the treatment with the same unit of measurement. Both compounds increase reactive oxygen species (ROS), decrease mitochondrial membrane potential (MMP) and enhance cytochrome c release in treated MDA-MB-231 cells. Isoasarone (2) markedly elevated caspase -8 and -3/7 activities and caused a decline in nuclear NF-kappaB translocation, suggesting extrinsic, death receptor-linked apoptosis pathway. Quantitative PCR results of MDA-MB-231 treated with asaricin (1) and isoasarone (2) showed altered expression of Bcl-2: Bax level. The inhibitory potency of these isolates may support the therapeutic uses of these compounds in breast cancer. PMID- 29174418 TI - Responses of human ankle muscles to mediolateral balance perturbations during walking. AB - During walking our balance is maintained by muscle action. In part these muscle actions automatically respond to the imbalance. This paper considers responses to balance perturbations in muscles around the ankle, peroneus longus (PL), tibialis anterior (TA) and soleus (SO). It is investigated if their action is related to previously observed balance mechanisms: the 'braking reaction' and the mediolateral ankle strategy. Subjects walked on a treadmill and received pushes to the left and pulls to the right in various phases of the gait cycle. Muscle actions were divided into medium latency R1 (100-150 ms), long latency R2 (170 250 ms), and late action R3 (270-350 ms). Short latency responses, before 100 ms, were not observed but later responses were prominent. With inward perturbations (e.g. pushes to the left shortly before or during stance of the right foot) responses in RPL were seen. The forward roll-over of the CoP was briefly stalled in mid stance, so that the heel was not lifted. Stance was shortened. With outward perturbations, pushes to the left shortly before or during stance of the left foot, responses in all three muscles, LTA, LSO, and LPL were seen. Our interpretation is that these muscle activations induce a 'braking reaction' but could also contribute to the 'mediolateral ankle strategy'. The resultant balance correction is small but fast, and so diminishes the need for later corrections by the stepping strategy. PMID- 29174419 TI - Co-infection with influenza-associated acute respiratory distress syndrome requiring extracorporeal membrane oxygenation. AB - The co-infection frequency and impact among influenza-associated acute respiratory distress syndrome (ARDS) patients requiring extracorporeal membrane oxygenation (ECMO) are not known. This retrospective observational analysis concerned data prospectively collected from patients admitted to our medical intensive care unit (ICU) who received ECMO support for influenza-associated ARDS between 2009-2016. Co-infection was defined as occurring within 48 h following ICU admission. Among the 77 ARDS patients requiring ECMO support, 39 (51%) developed co-infections, with Staphylococcus aureus [18 (46%) of the co-infected patients] being the most prevalent pathogen. Panton-Valentin leukocidin (PVL) producing S. aureus was isolated from 10 patients (56% of S. aureus co-infections and 26% of all co-infections). Co-infected patients were comparable with those without co-infection, except for BMI, initial disease severity and antibiotic treatment prior to admission. Co-infection was associated with higher in-ICU mortality (62% vs. 29%; P = 0.006) and with fewer ECMO-free days [median (IQR) 0 (0-19) vs. 23 (0-46); P = 0.004] and fewer mechanical ventilation-free days [0 (0 0) vs. 6 (0-35); P = 0.003] on Day 60. Multivariable analysis retained age >49 years, pre-ECMO Simplified Acute Physiology Score (SAPS) II score >70 and co infection as independent predictors of hospital mortality. In conclusion, co infection is frequent in ECMO-treated patients with influenza-associated ARDS, affecting ca. 50%, and is independently associated with poor outcome. Staphylococcus aureus was the most frequently identified pathogen, with a high rate of PVL-positive S. aureus. Whether specific therapy targeting PVL-producing S. aureus should be given remains to be determined. PMID- 29174421 TI - Morphological changes of vertebral compression fracture with intra-vertebral cleft treated with percutaneous vertebroplasty. AB - BACKGROUND: Vertebroplasty represents an established treatment option for osteoporotic vertebral compression fracture (OVCF), but its radiographic and clinical outcomes have not been clearly described in patients with intra vertebral cleft (IVC). The aim of this study was to assess vertebral height restoration, recollapse and change of back pain in OVCF patients with or without IVC. METHODS: The records of 108 patients with IVC (group I) and 233 patients without IVC (group II) were included in our analysis between March 2001 and February 2014. The heights of the anterior, middle, and posterior columns, as well as the wedge angle (WA) of the fractured vertebral body were measured. For each vertebral column, the mean height of the superior and inferior vertebral body served as reference. Pre-operative, postoperative, and final compression rates (CR), as well as restoration and recollapse rates were calculated for each column. Subjective back pain was assessed as the numeric rating scale (NRS) score. RESULTS: The overall incidence of IVC in OVCF patients who underwent vertebroplasty was 20.8% (127/611 patients). Group I showed significantly higher CR over the entire follow-up period, with the exception of CR for the anterior column at final follow-up, and CR for the posterior column throughout the follow up. The mean restoration rates at the anterior and middle column immediately after vertebroplasty were also significantly larger in group I. Recollapse rate in all columns was similar for groups I and II. The mean wedge angle was significantly larger in group I over the entire follow-up period. The groups did not differ in terms of NRS score at final follow-up. CONCLUSIONS: Vertebroplasty restores vertebral body heights and WA more effectively in OVCF patients with IVC, and provides satisfactory radiographic and clinical outcomes regardless of the presence of IVC.

PMID- 29174422 TI - Bioabsorbable magnesium versus standard titanium compression screws for fixation of distal metatarsal osteotomies - 3 year results of a randomized clinical trial. AB - BACKGROUND: For the treatment of hallux valgus commonly distal metatarsal osteotomies are performed. Persistent problems due to the hardware and the necessity of hardware removal has led to the development of absorbable implants. To overcome the limitations of formerly used materials for biodegradable implants, recently magnesium has been introduced as a novel implant material. This is the first study showing mid-term clinical and radiological (MRI) data after using magnesium implants for fixation of distal metatarsal osteotomies. MATERIAL AND METHODS: 26 patients with symptomatic hallux valgus were included in the study. They were randomly selected to be treated with a magnesium or standard titanium screw for fixation of a modified distal metatarsal osteotomy. The patients had a standardized clinical follow up and MRI investigation 3 years' post-surgery. The clinical tests included the range of motion of the MTP 1, the AOFAS, FAAM and SF-36 scores. Further on the pain was evaluated on a VAS. RESULTS: Eight patients of the magnesium group and 6 of the titanium group had a full clinical and MRI follow up 3 years postoperatively. One patient was lost to follow-up. All other patients could be interviewed, but denied full study participation. There was a significant improvement for all tested clinical scores (AOFAS, SF-36, FAAM, Pain-NRS) from pre-to postoperative investigation, but no statistically relevant difference between the groups. Magnesium implants showed significantly less artifacts in the MRI, no implant related cysts were found and the implant was under degradation three years postoperatively. CONCLUSION: In this study, bioabsorbable magnesium implants showed comparable clinical results to titanium standard implants 3 years after distal modified metatarsal osteotomy and were more suitable for radiologic analysis. LEVEL OF EVIDENCE: 2. PMID- 29174423 TI - Posterior spinal fusion for scoliosis after Fontan procedure: A case series. AB - BACKGROUND: As the surgical treatment of scoliosis after a Fontan procedure is very challenging due to the risk of various perioperative complications, case reports are scarce. We herein describe three patients who were successfully treated for scoliosis following a Fontan procedure and discuss their clinical and radiological outcomes. METHODS: We retrospectively reviewed three cases of scoliosis treated by posterior spinal fusion after a Fontan procedure. RESULTS: Mean preoperative major curve Cobb angle was 83.7 degrees , mean surgical time was 233.0 min, and mean blood loss was 1167 g. The mean correction rate of the major curve was 48.0%. Surgical outcome as evaluated by Scoliosis Research Society-22 patient questionnaires revealed acceptable results without any severe complications. CONCLUSIONS: Corrective surgery for scoliosis after a Fontan procedure becomes a stronger option if cardiac insufficiency is prevented during the perioperative period and a conservative plan is carried out with minimal invasiveness and operation time. PMID- 29174424 TI - Hemi-arthroplasty performed in a 109-year-old patient with intertrochanteric fracture: A case report. AB - The mortality of conservative treatment and the risk resulting from operation for elderly patients with femoral intertrochanteric fractures are high. Safety in the perioperative period and quicker recovery should be placed at the top priority for elderly patients with hip fractures. We reported a case of 109-year-old female patient with intertrochanteric fracture who has undergone the hemiarthroplasty in our center recently. With sciatic nerve and lateral cutaneous nerve block anesthesia, she was offered the artificial femoral head replacement in the lumbar plexus block after sufficient preoperative preparation. The surgery went well with minimally invasive cut, and the patient's recovery was satisfactory. PMID- 29174425 TI - Physiological response of a red tide alga (Skeletonema costatum) to nitrate enrichment, with special reference to inorganic carbon acquisition. AB - A classical red tide alga Skeletonema costatum was cultured under various nitrate levels to investigate its physiological response to nitrate enrichment combined with CO2 limitation. The higher nitrate levels increased content of photosynthetic pigments (Chl a and Chl c), electron transport rate in photosystem II, photosynthetic O2 evolution, and thus growth rate in S. costatum. On the other hand, the lower CO2 levels (3.5-4.4 MUmol kg-1 seawater) and higher pH (8.56-8.63) values in seawater were observed under higher nitrate conditions. Redox activity of plasma membrane and carbonic anhydrase in S. costatum was enhanced to address the reduced CO2 level at higher nitrate levels. In addition, the pH compensation point was enhanced and direct HCO3- use was induced at higher nitrate levels. These findings indicate that nitrate enrichment would stimulate the breakout of S. costatum dominated red tides via enhancing its photosynthetic performances, and maintain a quick growth rate under CO2 limitation conditions through improving its inorganic carbon acquisition capability. Our study sheds light on the mechanisms of S. costatum defeating CO2 limitation during algal bloom.

PMID- 29174427 TI - The serum leptin level in non-obese patients with obstructive sleep apnea. AB - OBJECTIVE: This study aimed to determine the association between the severity of obstructive sleep apnea (OSA) and the serum leptin level in non-obese OSA patients. METHODS: This prospective case-control study included non-obese OSA patients that presented with sleep-related disturbances and underwent polysomnography (PSG) between April 2015 and June 2016. The serum leptin level was measured and its relationship to PSG parameters was investigated. RESULTS: The study included 73 OSA patients (20 female and 53 male) with a mean age of 41.1+/-11.5 years and mean body-mass index (BMI) of 26.4+/-2.7kgm-2. The serum leptin level in 44 patients with moderate/severe OSA (AHI >=15) was 3.4+/-2.6ngmL 1, versus 4.5+/-3.8ngmL-1 in 29 patients with snoring/mild OSA (AHI <15) (P=0.20). There were not any correlations between any of the PSG parameters and the serum leptin level, but there was a significant correlation between the leptin level and BMI (r=0.345, P<0.01). CONCLUSION: The serum leptin level does not differ significantly between non-obese OSA patients with moderate/severe and snoring/mild OSA. Obesity is the primary factor associated with the serum leptin level. PMID- 29174428 TI - Radiation Dose, Local Disease Progression, and Overall Survival in Patients With Inoperable Non-Small Cell Lung Cancer After Concurrent Chemoradiation Therapy. AB - PURPOSE: To identify predictors of local control and overall survival (OS) for patients with inoperable non-small cell lung cancer treated with concurrent chemoradiation therapy. METHODS AND MATERIALS: We identified 491 patients with newly diagnosed stage IIIA-IIIB non-small cell lung cancer who had received 60 to 74 Gy (with concurrent chemotherapy) from January 2005 through December 2013 and grouped them by radiation dose received: 60 to 63 Gy, 64 to 66 Gy, 67 to 70 Gy, or 71 to 74 Gy. Local progression (LP) was that appearing within the high-dose volume (planning target volume plus 1-cm margin). Times to events were calculated from the completion of radiation therapy. Potential predictors of LP and OS were analyzed with a Cox regression model. RESULTS: Rates of LP for all patients were 16.2% at 1 year, 26.2% at 2 years, 31.0% at 3 years, 32.9% at 4 years, and 32.9% at 5 years; corresponding OS rates were 85.3%, 61.2%, 44.5%, 37.0%, and 31.6%. Median OS time was 21 months (range, 2.9-99.9 months). In multivariate analysis, receipt of 67 to 70 Gy was associated with improved LP-free survival (LPFS) relative to 60 to 63 Gy (hazard ratio [HR] 1.83, 95% confidence interval [CI] 1.062-3.150, P=.030) or 64 to 66 Gy (HR 2.14, 95% CI 1.159-3.969, P=.015). Non squamous histology (HR 0.23, 95% CI 0.114-0.478, P=.000), gross tumor volume (HR 1.00, 95% CI 1.000-1.003, P=.018) and induction chemotherapy (HR 1.86, 95% CI 1.239-2.778, P=.003) were independent predictors of LPFS. Local progression-free survival was the only independent predictor of OS (HR 2.71, 95% CI 1.331-5.512, P=.006). Incidence of grade >=3 radiation pneumonitis was no different among dose groups (P=.307). CONCLUSIONS: Squamous histology, large tumor volumes, and receipt of induction chemotherapy all predicted worse LPFS. Doses of 67 to 70 Gy were associated with improved LP-free survival after chemoradiotherapy. The link between LP and reduced OS suggests that more effective local control strategies are warranted. PMID- 29174430 TI - The expanding role of innate lymphoid cells and their T-cell counterparts in gastrointestinal cancers. AB - Innate lymphoid cells (ILCs) contribute to the regulation of gastrointestinal (GI) homeostasis. Over the past 15 years, there has been a large effort to dissect the mechanisms required for GI homeostasis, with a major focus on different immune cell populations and the cytokines that they produce. In contrast to T-helper (Th) cells, ILCs respond rapidly to cytokines in their microenvironment in the absence of specific antigens; however, once activated both cell populations have similar effector functions. Two effector cytokines produced by both ILC3 and Th17 cell populations, Interleukin (IL)-17 and IL-22, have taken center stage for their ability to signal directly to GI epithelial cells and promote epithelial cell survival. In this review, we outline our current understanding of ILCs in the GI tract, and focus on GI cancers associated with aberrant production of IL-17 and IL-22. We highlight evidence from both mouse and patient-based analyses and discuss how tumor cells may hijack the potential evolutionary redundancy of these two cell populations. PMID- 29174429 TI - Evaluating the evidence for non-monotonic dose-response relationships: A systematic literature review and (re-)analysis of in vivo toxicity data in the area of food safety. AB - This study aims to evaluate the evidence for the existence of non-monotonic dose responses (NMDRs) of substances in the area of food safety. This review was performed following the systematic review methodology with the aim to identify in vivo studies published between January 2002 and February 2015 containing evidence for potential NMDRs. Inclusion and reliability criteria were defined and used to select relevant and reliable studies. A set of six checkpoints was developed to establish the likelihood that the data retrieved contained evidence for NMDR. In this review, 49 in vivo studies were identified as relevant and reliable, of which 42 were used for dose-response analysis. These studies contained 179 in vivo dose-response datasets with at least five dose groups (and a control group) as fewer doses cannot provide evidence for NMDR. These datasets were extracted and analyzed using the PROAST software package. The resulting dose-response relationships were evaluated for possible evidence of NMDRs by applying the six checkpoints. In total, 10 out of the 179 in vivo datasets fulfilled all six checkpoints. While these datasets could be considered as providing evidence for NMDR, replicated studies would still be needed to check if the results can be reproduced to rule out that the non-monotonicity was caused by incidental anomalies in that specific study. This approach, combining a systematic review with a set of checkpoints, is new and appears useful for future evaluations of the dose response datasets regarding evidence of non-monotonicity. PMID- 29174431 TI - Pediatric thyroid cancer patients referred to high-volume facilities have improved short-term outcomes. AB - BACKGROUND: Thyroid cancer is the most common endocrine malignancy in children, albeit still rare. This study sought to measure the association between outcomes and case volume of the treatment facility for pediatric patients with thyroid cancer. METHODS: The National Cancer Data Base (1998-2011) was queried for all pediatric patients (age <= 18 years) with thyroid cancer. Demographic, clinical, and pathologic features were evaluated for all patients. Case volume of the treating facility was defined as the number of pediatric thyroid cancer patients at that facility during the study period. Restricted cubic spline modeling was used to determine a volume threshold associated with decreased risk of 30-day readmission. Patients were assigned to volume groups based on this threshold. Logistic regression was utilized to estimate the effect of volume on 30-day readmission. RESULTS: In total, 4,466 patients met inclusion criteria. The majority were girls (79.1%), white (86.1%), and underwent total thyroidectomy (86.9%). Compared with patients treated at the low-volume facilities, those treated at the high-volume facilities were more likely to have medullary thyroid cancer (10.7% versus 3.7%) and undergo total thyroidectomy (90.8% versus 86.3%) (all P < .01). After adjustment, treatment at low-volume facilities was associated with an increased likelihood of readmission after operative treatment (odds ratio = 3.52, P = .01). CONCLUSION: Pediatric patients with thyroid cancer treated at low-volume facilities are more likely to be readmitted after thyroid surgery than patients treated at high-volume facilities. Providers should consider the case volume status at the treating facility when referring these children for thyroid surgery. PMID- 29174432 TI - Primary aldosteronism: making sense of partial data sets from failed adrenal venous sampling-suppression of adrenal aldosterone production can be used in clinical decision making. AB - BACKGROUND: It has been suggested that accurate clinical decisions may be made in patients with primary aldosteronism (PA) in the setting of failed cannulation of an adrenal vein, thereby utilizing only data from either right or left adrenal venous sampling (AVS) alone. METHODS: Retrospective analysis was performed for all patients with PA who underwent successful bilateral AVS. Adrenal vein/inferior vena cava index (AV/IVC index) was calculated by dividing aldosterone/cortisol ratio of the adrenal vein by aldosterone/cortisol ratio in the inferior vena cava, as described in a previously published study. We examined the rates of inappropriate adrenalectomy and failure to recognize unilateral disease when previously published cutoffs are used. RESULTS: Inclusion criteria were met in 150 patients; 61 with bilateral and 89 with unilateral disease. AV/IVC index cutoff of <=0.5 to predict contralateral disease would have not led to any inappropriate adrenalectomies and would have missed 19% of patients with unilateral disease; AV/IVC index cutoff of >=5.5 to predict ipsilateral unilateral disease would have resulted in inappropriate adrenalectomy in 18% of patients (95% CI 8-34%, P < .01) and would have not recognized 55% of patients with unilateral disease (P < .01). CONCLUSION: The cortisol-corrected adrenal vein/inferior vena cava aldosterone index with a cutoff value of <=0.5 performed well in identifying patients with contralateral unilateral disease. AV/IVC index of >=5.5 cannot be used to reliably diagnose ipsilateral unilateral disease because 18% of patients undergoing adrenalectomy based on this cutoff would have bilateral disease. PMID- 29174433 TI - Novel chimeric parapoxvirus CF189 as an oncolytic immunotherapy in triple negative breast cancer. AB - BACKGROUND: Triple-negative breast cancer is an aggressive subtype of breast cancer with high recurrence rate and poor prognosis. Here we describe a novel, genetically engineered parapoxvirus that efficiently kills triple-negative breast cancer. METHODS: A novel chimeric parapoxvirus (CF189) was generated via homologous recombination and identified through high-throughput screening. Cytotoxicity was assayed in vitro in 4 triple-negative breast cancer cell lines. Viral replication was examined through standard plaque assay. Orthotopic triple negative breast cancer xenografts were generated by MDA-MB-468 implantation into the 2nd and 4th mammary fat pads of athymic nude mice and treated with the virus. RESULTS: Chimeric parapoxvirus (CF189) demonstrated dose-dependent cytotoxicity at low multiplicity of infection, with > 80% cell death 6 days after treatment. Significant reductions in tumor size were observed 2 weeks after intratumoral injection at doses as low as 103 plaque-forming units (PFU) compared with control (P < 0.01). In addition, abscopal effect (shrinkage of noninjected remote tumors) was clearly demonstrated. CONCLUSION: Chimeric parapoxvirus (CF189) demonstrated efficient cytotoxicity in vitro and potent antitumor effect in vivo at doses as low as 103 PFU. These are data encouraging of clinical development for this highly potent agent against triple-negative breast cancer. PMID- 29174434 TI - Incidence and impact of adverse drug events contributing to hospital readmissions in kidney transplant recipients. AB - BACKGROUND: The incidence and impact of adverse drug events (ADEs) leading to hospitalization and as a predominant risk factor for late graft loss has not been studied in transplantation. METHODS: This was a longitudinal cohort study of adult kidney recipients transplanted between 2005 and 2010 and followed through 2013. There were 3 cohorts: no readmissions, readmissions not due to an adverse drug event, and adverse drug events contributing to readmissions. The rationale of the adverse drug events contribution to the readmission was categorized in terms of probability, preventability, and severity. RESULTS: A total of 837 patients with 963 hospital readmissions were included; 47.9% had at least one hospital readmission and 65.0% of readmissions were deemed as having an ADE contribute. The predominant causes of readmissions related to ADEs included non opportunistic infections (39.6%), opportunistic infections (10.5%), rejection (18.1%), and acute kidney injury (11.8%). Over time, readmissions due to under immunosuppression (rejection) significantly decreased (-1.6% per year), while those due to over-immunosuppression (infection, cancer, or cytopenias) significantly increased (2.1% increase per year [difference 3.7%, P = .026]). Delayed graft function, rejection, creatinine, graft loss, and death were all significantly greater in those with an ADE that contributed to a readmission compared the other two cohorts (P < .05). CONCLUSION: These results demonstrate that ADEs may be associated with a significant increase in the risk of hospital readmission after kidney transplant and subsequent graft loss. PMID- 29174435 TI - Dopamine in high-risk populations: A comparison of subjects with 22q11.2 deletion syndrome and subjects at ultra high-risk for psychosis. AB - Striatal dopamine (DA) dysfunction has been consistently reported in psychotic disorders. Differences and similarities in the pathogenesis between populations at clinical and genetic risk for developing psychosis are yet to be established. Here we explored markers of dopamine (DA) function in subjects meeting clinically ultra-high risk criteria for psychosis (UHR) and in subjects with 22q11.2 deletion syndrome (22q11DS), a genetic condition associated with significant risk for developing psychotic disorders. Single Photon Emission Computed Tomography (SPECT) with 123I-labelled iodobenzamide ([123I]IBZM) was used to measure striatal DA D2/3 receptor binding potential (D2R BPND). Also, peripheral DAergic markers were assessed in serum and urine (plasma prolactin (pPRL), plasma homovanillic acid (pHVA) and urine DA(uDA)). No significant difference in striatal D2R BPND was found between UHR and 22q11DS subjects. Compared to UHR subjects, pPRL and pHVA were lower and uDA levels were higher in the 22q11DS subjects. However, after correcting for age and gender, only pPRL as significantly lower in the 22q11DS patients. These results may suggest that there are differences in DAergic markers between subjects with UHR and with 22q11DS that may reflect differences in the pathways to psychosis. However, bigger samples are needed to replicate these findings. PMID- 29174436 TI - Reduced frontal grey matter, life history of aggression, and underlying genetic influence. AB - Physically healthy, adult, same-sexed twins (n = 287) from a population-based twin cohort underwent high-resolution magnetic resonance imaging (MRI) to identify fronto-limbic brain regions significantly associated with lifetime history of aggression. MRI scans used a 3D magnetization-prepared rapid acquisition gradient-echo (MP-RAGE) sequence, for voxel-based morphometry (VBM) and history of aggressive behavior was assessed using the Life History of Aggression measure. Aggression had modest, inverse associations with grey matter volume (GMV) in medial prefrontal cortex (mPFC, b = -0.20, se = 0.05, p < 0.001) and lateral prefrontal cortex (lPFC, b = -0.23, se = 0.06, p < 0.001). These associations were not confounded by other demographic, psychiatric, or personality factors. Biometrical twin analyses revealed significant heritabilities of 0.57 for GMV in the mPFC cluster and 0.36 for GMV in the lPFC cluster. Genetic factors accounted for the majority of the phenotypic correlations between aggression and mPFC GMV (85.3%) and between aggression and lPFC GMV (63.7%). Reduced GMV of prefrontal brain regions may be a neuronal characteristic of individuals with substantial histories of aggressive behavior regardless of psychiatric diagnosis. As such, these data suggest an anatomical correlate, with a possible genetic etiology, associated with functional deficits in social-emotional information processing. PMID- 29174437 TI - Neural simulation mechanisms and social-emotional function in schizophrenia. AB - Impairment in simulation, i.e., the generation of internal representations of experiences, may contribute to social dysfunction in schizophrenia spectrum disorders (SZ). Using a novel fMRI task, we identified neural representations generated during simulation of sensorimotor experiences and evaluated their associations with socioemotional function in 19 individuals with SZ and 24 psychiatrically-healthy controls (HC). Participants watched videos depicting a painful sensorimotor experience in the hand or foot of another person and were then asked to imagine how unpleasant it would be to undergo that experience themselves, eliciting simulation. A localizer task identified regions-of-interest (ROIs) within each participant's sensorimotor cortices (SC) recruited by firsthand sensory experiences in hands and feet. Simulation engaged these ROIs in HC and SZ. Simulation-related activation in ROIs did not differ between groups but was associated with participants' social function. Findings indicate that simulation elicits specific neural representations within the SC and the strength of these representations might be linked to social function. PMID- 29174438 TI - Mendelian randomization analysis of cholesteryl ester transfer protein and subclinical atherosclerosis: A population-based study. AB - BACKGROUND: Several trials to prevent cardiovascular disease by inhibiting cholesteryl ester transfer protein (CETP) have failed, except Randomized EValuation of the Effects of Anacetrapib through Lipid-modification. Thus far, it is unclear to what extent CETP is causally related to measures of atherosclerosis. OBJECTIVE: The aim of the article was to study the causal relationship between genetically determined CETP concentration and carotid intima media thickness (cIMT) in a population-based cohort study. METHODS: In the Netherlands Epidemiology of Obesity study, participants were genotyped, and cIMT was measured by ultrasonography. We examined the relation between a weighted genetic risk score for CETP concentration, based on 3 single-nucleotide polymorphisms that have previously been shown to largely determine CETP concentration and cIMT using Mendelian randomization in the total population and in strata by sex, Framingham 10-year risk, (pre)diabetes, high-density lipoprotein cholesterol, triglycerides, and statin use. RESULTS: We analyzed 5655 participants (56% women) with a mean age of 56 (range 44-66) years, body mass index of 26 (range 17-61) kg/m2, and serum CETP of 2.47 (range 0.68-5.33) MUg/mL. There was no evidence for a causal relation between genetically determined CETP and cIMT in the total population, but associations were differently directed in men (16 MUm per MUg/mL increase in genetically determined CETP; 95% confidence interval: -8, 39) and women (-8 MUm; -25, 9). Genetically determined CETP appeared to be associated with cIMT in normoglycemic men (26 MUm; -1, 52) and in (pre)diabetic women (48 MUm; -2, 98). CONCLUSION: In this population-based study, there was no causal relation between genetically determined CETP concentration and cIMT in the total population although we observed directionally differing effects in men and women. Stratified results suggested associations in individuals with different cardiometabolic risk factor profiles, which require replication. PMID- 29174439 TI - Vascular inflammation and metabolic activity in hematopoietic organs and liver in familial combined hyperlipidemia and heterozygous familial hypercholesterolemia. AB - BACKGROUND: Familial dyslipidemias of either heterozygous (heFH) or combined (FCH) type lead to accelerated atherogenesis and increased cardiovascular risk. OBJECTIVE: The aim of this study was to investigate in statin-naive adult patients with familial dyslipidemias whether inflammatory activation and liver, spleen and bone marrow metabolic activity differ compared with normolipidemic subjects and between dyslipidemic groups. METHODS: Fourteen patients with FCH, 14 with heFH, and 14 normolipidemic individuals were enrolled. Serum lipids, high sensitivity C-reactive protein, and fibrinogen levels were measured, followed by 18F-fluorodeoxyglucose positron-emission tomography/computed tomography imaging. Radiotracer uptake in the aortic wall, spleen, bone marrow, and liver was quantified as tissue-to-background ratio (TBR). RESULTS: Patients with heFH had significantly higher low-density lipoprotein levels compared with those with FCH and controls (P < .001). However, aortic TBRs were higher in FCH compared with heFH patients and controls (P = .02 and P < .001, respectively). FCH patients exhibited higher FDG uptake in the spleen compared with controls (P = .05). In addition, FCH exhibited higher bone marrow FDG uptake compared with heFH patients and controls (P = .03 and P = .02, respectively). FCH had higher liver uptake compared with heFH patients and controls (P < .001 for both). Significant correlations were observed between inflammatory biomarkers and imaging indices as well as between aortic TBR and FDG uptake of hematopoietic organs and liver. CONCLUSIONS: Systemic, as well as vascular inflammation and spleen, bone marrow, and hepatic metabolic activity are increased in patients with FCH despite lower levels of low-density lipoprotein. PMID- 29174440 TI - Immunochemotherapy mediated by thermosponge nanoparticles for synergistic anti tumor effects. AB - The efficacy of immunotherapy was demonstrated to be compromised by reduced immunogenicity of tumor cells and enhanced suppressive properties of the tumor microenvironment in cancer treatment. There is growing evidence that low-dose chemotherapy can modulate the immune system to improve the anti-tumor effects of immunotherapy through multiple mechanisms, including the enhancement of tumor immunogenicity and reversal of the immunosuppressive tumor microenvironment. Here, we fabricated thermosponge nanoparticles (TSNs) for the co-delivery of chemotherapeutic drug paclitaxel (PTX) and immunostimulant interleukin-2 (IL-2) to explore the synergistic anti-tumor effects of chemotherapy and immunotherapy. The distinct temperature-responsive swelling/deswelling character facilitated the effective post-entrapment of cytokine IL-2 in nanoparticles by a facile non solvent mild incubation method with unaffected bioactivity and favorable pharmacokinetics. PTX and IL-2 co-loaded TSNs exhibited significant inhibition on tumor growth and metastasis, and prolonged overall survival for tumor-bearing mice compared with the corresponding monotherapies. The synergistic effect was evidenced from the remodeled tumor microenvironment in which low-dose chemotherapeutics disrupted the immunosuppressive tumor microenvironment and enhanced tumor immunogenicity, and immunostimulant cytokine promoted the anti tumor immune response of immune effector cells. The immunochemotherapy mediated by this thermosponge nanoplatform may provide a promising treatment strategy against cancer. PMID- 29174441 TI - Hollow microneedle-mediated micro-injections of a liposomal HPV E743-63 synthetic long peptide vaccine for efficient induction of cytotoxic and T-helper responses. AB - Recent studies have shown that intradermal vaccination has great potential for T cell-mediated cancer immunotherapy. However, classical intradermal immunization with a hypodermic needle and syringe has several drawbacks. Therefore, in the present study a digitally controlled hollow microneedle injection system (DC-hMN iSystem) with an ultra-low dead volume was developed to perform micro-injections (0.25-10MUL) into skin in an automated manner. A synthetic long peptide derived from human papilloma virus formulated in cationic liposomes, which was used as a therapeutic cancer vaccine, was administered intradermally by using the DC-hMN iSystem. Fused silica hollow microneedles with an inner diameter of 50MUm and a bevel length of 66+/-26MUm were successfully fabricated via hydrofluoric acid etching. Upon piercing these microneedles into the skin using a protrusion length of 400MUm, microneedles were inserted at a depth of 350+/-55MUm. Micro-injections of 1-10MUL had an accuracy between 97 and 113% with a relative standard deviation (RSD) of 9%, and lower volumes (0.25 and 0.5MUL) had an accuracy of 86-103% with a RSD of 29% in ex vivo human skin. Intradermal administration of the therapeutic cancer vaccine via micro-injections induced strong functional cytotoxic and T helper responses in mice, while requiring much lower volumes as compared to classical intradermal immunization. In conclusion, by using the newly developed DC-hMN-iSystem, very low vaccine volumes can be precisely injected into skin in an automated manner. Thereby, this system shows potential for minimally-invasive and potentially pain-free therapeutic cancer vaccination. PMID- 29174442 TI - Health policy: A reflection and look forward. PMID- 29174443 TI - Persistent Dentoalveolar Pain Disorder: A Comprehensive Review. AB - INTRODUCTION: Persistent dentoalveolar pain of idiopathic origin represents a diagnostic challenge for the dentist and physician alike. Disagreement on taxonomy and diagnostic criteria presents a significant limit to the advancement of research in the field. Patients struggle with a lack of knowledge by dental and medical professionals, diagnostic delays, and unnecessary treatments. METHODS: A PubMed search was performed as of January 1, 2017 by using the terms atypical odontalgia, phantom tooth pain, persistent idiopathic facial pain, painful posttraumatic trigeminal neuropathy, idiopathic toothache, persistent dentoalveolar pain disorder, nonodontogenic tooth pain, and continuous neuropathic orofacial pain. Three hundred forty-five abstracts were screened, and 128 articles that were pertinent to the topic went through full-text reading. RESULTS: Case reports and narrative reviews constitute the majority of available literature. Several retrospective case-control studies investigated the clinical characteristics, pathophysiology, and diagnostic processes. Treatment strategies were evaluated in only 7 open-label and 2 randomized controlled trials. CONCLUSIONS: Persistent dentoalveolar pain disorder is likely neuropathic in origin, but pathophysiological mechanisms to explain the onset and persistence of the pain are still far from understood. A correct diagnosis should be established before treatments are performed. Researchers should reach an agreement on the diagnostic criteria to enable a coherent research path to better understand the condition and reduce patient suffering.

PMID- 29174445 TI - Burn injury models of care: A review of quality and cultural safety for care of Indigenous children. AB - Safety and quality in the systematic management of burn care is important to ensure optimal outcomes. It is not clear if or how burn injury models of care uphold these qualities, or if they provide a space for culturally safe healthcare for Indigenous peoples, especially for children. This review is a critique of publically available models of care analysing their ability to facilitate safe, high-quality burn care for Indigenous children. Models of care were identified and mapped against cultural safety principles in healthcare, and against the National Health and Medical Research Council standard for clinical practice guidelines. An initial search and appraisal of tools was conducted to assess suitability of the tools in providing a mechanism to address quality and cultural safety. From the 53 documents found, 6 were eligible for review. Aspects of cultural safety were addressed in the models, but not explicitly, and were recorded very differently across all models. There was also limited or no cultural consultation documented in the models of care reviewed. Quality in the documents against National Health and Medical Research Council guidelines was evident; however, description or application of quality measures was inconsistent and incomplete. Gaps concerning safety and quality in the documented care pathways for Indigenous peoples' who sustain a burn injury and require burn care highlight the need for investigation and reform of current practices. PMID- 29174446 TI - Protective effect of ethyl acetate fraction of Drynaria quercifolia against CCl4 induced rat liver fibrosis via Nrf2/ARE and NFkappaB signalling pathway. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Drynaria quercifolia rhizome is traditionally used as hepatoprotective drug especially in chronic jaundice. AIM OF THE STUDY: The present study was undertaken to scientifically evaluate the efficacy of D. quercifolia rhizome against liver fibrosis. MATERIALS AND METHODS: D. quercifolia rhizome crude extract (DQ) and its fractions of hexane (HDQ), ethyl acetate (EDQ), butanol (BDQ) were evaluated in vitro using primary hepatocytes and RAW 264.7 cells. In vivo anti-liver fibrotic activity of EDQ was assessed using CCl4 induced liver fibrosis in Wistar rats and serum biochemical parameters (AST, ALT, ALP, SB, cholesterol), MDA, PT, INR, GSH, SOD, CAT, liver glycogen, serum albumin levels were monitored. qRT-PCR analysis of TNF-alpha, COX-2, iNOS were performed. ELISA method was used to estimate TNF-alpha, COX-1 & 2. Histopathological studies like H & E, Masson's trichrome, immunohistochemistry staining for alpha-SMA, TIMP 1, Nrf2 were conducted. LC-Q-TOF-MS analysis of EDQ was conducted. RESULTS: In vitro activity guided fractionation of D. quercifolia revealed EDQ as active fraction when compared to other extracts. EDQ treatment significantly inhibited the expression of alpha-SMA, TIMP-1, COX-2, TNF-alpha, iNOS and increased the levels of Nrf2 in rat liver fibrosis. LC-Q-TOF-MS analysis of EDQ confirmed the presence of naringin and naringenin. CONCLUSION: The anti-liver fibrotic activity of EDQ is via inhibition of NFkappaB signalling pathway, antioxidant response through Nrf2 activation and further inhibition of HSC activation. PMID- 29174447 TI - Genetic diversity of Hepatozoon spp. in Hydrochoerus hydrochaeris and Pecari tajacu from eastern Amazon. AB - This study aimed to identify and characterize genetically species of the genus Hepatozoon detected in Hydrochoerus hydrochaeris (capybaras) and Pecari tajacu (collared peccaries) from two localities from the Eastern Amazon. Blood samples from 196 free-living H. hydrochaeris from Marajo Island and 109 P. tajacu kept in captivity in Belem, Para, were collected and analyzed for the presence of Hepatozoon spp. Partial sequences of the 18S rRNA gene were obtained and analyzed in comparison to others available in the NCBI database. Our results demonstrated a high prevalence of Hepatozoon canis in both mammals and the existence of four haplotypes of Hepatozoon spp., three of Hepatozoon canis and one of Hepatozoon cuestensis, found only in H. hydrochaeris. In addition, these data increase the genetic diversity of H. canis from the Eastern Amazon, as well as reporting, for the first time, the infection of mammals by H. cuestensis and P. tajacu by H. canis. PMID- 29174448 TI - Conspecific hyperparasitism: An alternative route for Borrelia hermsii transmission by the tick Ornithodoros hermsi. AB - Ixodid and argasid ticks may hyperparasitize other individuals of their own species to acquire a blood meal, however most accounts are based on single observations and the behavior has rarely been studied. While maintaining laboratory colonies of Ornithodoros species, we noticed that unfed ticks occasionally fed on other ticks that were feeding on mice, and unfed ticks parasitized engorged ticks when confined together in tubes. Therefore, we investigated hyperparasitism by Ornithodoros hermsi and the ability of these ticks to acquire and transmit the relapsing fever spirochete Borrelia hermsii when feeding on other ticks. Various combinations of unfed and recently engorged male, female and nymphal ticks were confined for 1-2h as individual pairs or in groups, then examined to determine the number of ticks that acquired blood by feeding on others. Unfed O. hermsi males were far more likely to hyperparasitize other ticks than were females and nymphs, as 78.6% of males (114 of 145 ticks) fed when confined with recently engorged ticks. Unfed females and nymphs also hyperparasitized other ticks but far less frequently (only 6.7% combined; 17 of 254 ticks). Infection experiments demonstrated that unfed males acquired B. hermsii when parasitizing nymphs that had recently engorged on a spirochetemic mouse, and unfed infected males transmitted spirochetes to recently engorged nymphs. Some ticks infected via hyperparasitism subsequently transmitted B. hermsii to mice. Hyperparasitism by O. hermsi occurred more frequently than expected, although possibly influenced by our experimental design. The significance of this behavior as it may influence the horizontal transfer of B. hermsii in nature is not known but worthy of future consideration. PMID- 29174449 TI - Risk factors for tick exposure in suburban settings in the Northeastern United States. AB - Prevention of tick-borne diseases requires an understanding of when and where exposure to ticks is most likely. We used an epidemiologic approach to define these parameters for residents of a Lyme-endemic region. Two persons in each of 500 Connecticut households were asked to complete a log each night for one week during June, 2013. Participants recorded their whereabouts in 15min increments (indoors, outdoors in their yard, outdoors on others' private property, or outdoors in public spaces) and noted each day whether they found a tick on themselves. Demographic and household information was also collected. Logs were completed for 934 participants in 471 households yielding 51,895 time-place observations. Median participant age was 49 years (range 2-91 years); 52% were female. Ninety-one participants (9.8%) reported finding a tick during the week, with slightly higher rates among females and minors. Household factors positively associated with finding a tick included having indoor/outdoor pets (odds ratio (OR)=1.7; 95% confidence interval (CI): 1.1-2.9), the presence of a bird feeder in the yard (OR=1.9; CI:1.2-3.2), and presence of an outdoor dining area (OR=2.2; CI:1.1-4.3). Individual factors associated with finding a tick on a given day were bathing or showering (OR=3.7; CI:1.3-10.3) and hours spent in one's own yard (OR=1.2, CI:1.1-1.3). Nineteen participants found ticks on multiple days, more than expected assuming independence (p<0.001). Participants who found ticks on multiple days did not spend more time outdoors but were significantly more likely to be male than those finding ticks on a single day (p<0.03). Our findings suggest that most tick exposures in the study area occurred on private property controlled by the respective homeowner. Interventions that target private yards are a logical focus for prevention efforts. PMID- 29174450 TI - We all make choices: A decision analysis framework for disposition decision in the ED. AB - BACKGROUND: Emergency Department (ED) providers' disposition decision impacts patient care and safety. The objective of this brief report is to gain a better understanding of ED providers' disposition decision and risk tolerance of associated outcomes. METHODS: We synthesized qualitative and quantitative methods including decision mapping, survey research, statistical analysis, and word clouds. Between July 2017 and August 2017, a 10-item survey was developed and conducted at the study hospital. Descriptive and statistical analyses were used to assess the relationship between the participant characteristics (age, gender, years of experience in the ED, and level of expertise) and risk tolerance of outcomes (72-h return and negative outcome) associated with disposition decision. Word clouds facilitated prioritization of qualitative responses regarding information impacting and supporting the disposition decision. RESULTS: Total of 46 participants completed the survey. The mean age was 39.5 (standard deviation (SD) 10years), and mean years of experience was 9.6years (SD 8.7years). Decision map highlighted the connections between patient-, provider-, and system-related factors. Survey results showed that negative outcome resulted in less risk tolerance compared to 72-h return. Chi-square tests did not provide sufficient evidence to indicate that the responses are independent of participants characteristics - except age and the risk of 72-h return (p=0.046). CONCLUSION: Discharge decision making in the ED is complex as it involves interconnected patient, provider, and system factors. Synthesizing qualitative and quantitative methods promise enhanced understanding of how providers arrive to disposition decision, as well as safety and quality of care in the ED.

PMID- 29174452 TI - Diagnosing centrally located pulmonary embolisms in the emergency department using point-of-care ultrasound. AB - OBJECTIVE: The study objective was to investigate the combined accuracy of right heart strain on focused cardiac ultrasound (FOCUS) and deep vein thrombosis (DVT) on compression ultrasound (CUS) for identification of centrally located pulmonary embolism (PE) diagnosed on computed tomography pulmonary angiography (CTPA). METHODS: This was a prospective observational study using a convenience sample of patients undergoing CTPA in the emergency department (ED) for evaluation of PE. Patients received a FOCUS looking for right heart strain (McConnell's sign, septal flattening, right ventricular enlargement or tricuspid annular plane systolic ejection (TAPSE) <17mm) and a CUS looking for DVT. Ultrasounds were interpreted by both the investigator performing the ultrasound and the principal investigator independently. RESULTS: There were 199 patients enrolled in the study, with 46/199 (23.1%) positive for a PE. Of these, 20/46 (43.5%) PE's were located centrally. Of those with a PE, 20/46 (43.5%) had an associated DVT identified on bedside ultrasound. Among patients with a proximal PE, 18/20 (90.0%) had evidence of right heart strain and the combination of lower extremity CUS and FOCUS was 100% sensitive. Diagnostic accuracy of ultrasound was much lower for peripherally located PEs. CONCLUSIONS: Emergency physician-performed bedside ultrasound may be sufficient to exclude the presence of centrally located PE, as the sensitivity in this study was 100%. Additionally, several patients with PE may qualify for early anticoagulation when DVT is identified, and further research in indicated to determine whether these patients ultimately require CTPA given identical treatment algorithms in the absence of RV strain or biomarker elevation. PMID- 29174453 TI - Correlation of high flow nasal cannula outlet area with gas clearance and pressure in adult upper airway replicas. AB - BACKGROUND: Primary benefits of high flow nasal cannula therapy include washout of carbon dioxide rich exhaled gas and increased airway pressures during tidal breathing. This work reports on the influence of high flow nasal cannula outlet area on upper airways gas clearance and tracheal pressures using measurements in five realistic adult nose-throat airway replicas. METHODS: Two commercial high flow nasal cannulas and one generic nasal cannula of varying size were compared. 100% oxygen was supplied via cannulas at flow rates ranging from 30 to 90l/min to replicas originally filled with air, and oxygen concentrations at the larynx and trachea were compared over time. Additionally, and separately, replicas were connected to a mechanical lung simulator to simulate tidal breathing while undergoing high flow nasal cannula therapy, with tracheal pressure-time waveforms recorded. FINDINGS: Faster gas clearance corresponded with higher flow rates (P<0.001), and with smaller cannula outlet area (P<0.001). Observed pressures were in approximate agreement with limited available in-vivo data in the literature. Between 0 and 60L/min cannula flow rates, tracheal positive end expiratory pressures increase was greater with the smallest cannula (?PPEEP=785SD(185) Pa) compared to the largest cannula (?PPEEP=380SD(120)Pa). Regression analysis indicates that positive end expiratory pressure is proportional to the square of flow velocities exiting the cannula and nares (R2=0.906). INTERPRETATION: Since increased pressure and clearance rate have been associated with improved clinical outcomes in previous studies, our results suggest that smaller cannula outlet area may be preferable. PMID- 29174454 TI - Closed incision negative pressure therapy decreases complications after periprosthetic fracture surgery around the hip and knee. AB - INTRODUCTION: Periprosthetic fractures (PPFXs) are becoming increasingly common following total hip arthroplasty (THA) and total knee arthroplasty (TKA). Patients sustaining PPFXs face considerable perioperative morbidity, with relatively increased rates of surgical site infection. We sought to evaluate the efficacy of closed-incision negative-pressure wound therapy (ciNPT) in decreasing perioperative wound complications following lower extremity periprosthetic fracture surgery. METHODS: We performed a retrospective review of 69 consecutive patients who underwent surgery to address lower extremity periprosthetic fractures around hip or knee implants performed over a 6.5-year period. The population was divided into two groups based on the surgical dressing used at the conclusion of the procedure: (1) a sterile, antimicrobial hydrofiber dressing, or (2) ciNPT. There were no baseline demographic differences between the two groups. Rates of wound complications, surgical site infection, and reoperation related to the surgical site were compared between groups. Continuous variables were analyzed using a student's t-test, and categorical variables using either chi square or fisher's exact test. RESULTS: Patients treated with ciNPT developed fewer wound complications (4% vs. 35%; p=0.002), fewer deep infections (0% vs. 25%; p=0.004), and underwent fewer reoperations related to the surgical site (4% vs. 25%; p=0.021) compared to patients treated with standard of care. CONCLUSIONS: Our findings suggest that ciNPT may reduce wound complications, SSIs, and reoperations in patients undergoing lower extremity periprosthetic fracture surgery. This is the first study to investigate ciNPT as a treatment for periprosthetic fracture surgery, and has the potential to change the postoperative management of these patients. PMID- 29174455 TI - High power beta electron device - Beyond betavoltaics. AB - Developing watt level power sources with beta emitting radioisotopes has been limited by the inability to utilize high energy (> 100KeV) beta emitters at high radioisotope loadings without damaging the energy conversion materials. A new type of beta electron power source is described that removes those restrictions. The approach contains the radioisotope in a beta transparent titanium tube and confines beta electrons emitted through the tube wall to spiral trajectories around the tube with an axial magnetic field. The confined beta electrons dissipate energy though multiple interactions with surrounding excimer precursor gas atoms to efficiently generate photons. Photovoltaic cells convert the photons to electrical power. Since the beta electrons dissipate energy in the excimer precursor gas, the device can be loaded with more than 1013Bq of radioisotope to generate 100 milliwatt to watt levels of electrical power without damaging the device materials or degrading its performance. The power source can use a variety of beta radioisotopes and scales by stacking the devices. PMID- 29174456 TI - Prevalence of and risk factors for mental disorders in refugees. AB - Given the increasing numbers of refugees worldwide, the prevalence of their mental disorders is relevant for public health. Prevalence studies show that, in the first years of resettlement, only post-traumatic stress disorder (PTSD) rates are clearly higher in refugees than in host countries' populations. Five years after resettlement rates of depressive and anxiety disorders are also increased. Exposure to traumatic events before or during migration may explain high rates of PTSD. Evidence suggests that poor social integration and difficulties in accessing care contribute to higher rates of mental disorders in the long-term. Policy and research implications are discussed. PMID- 29174457 TI - What does the shape of our back tell us? Correlation between sacrum orientation and lumbar lordosis. AB - BACKGROUND CONTEXT: Sacral slope and lumbar lordosis (LL) have been studied extensively in recent years via X-ray examinations and strongly correlate with each other. This raises, first, the question of the reproducibility of this correlation in multiple standing phases and, second, if this correlation can be achieved using non-radiological measurement tools. PURPOSE: This study aimed (1) to determine the extent to which the back-shape measurements correspond to the correlations between the sacral slope and LL found in previous radiological investigations, (2) to identify a possible effect of age and gender on this correlation, and (3) to evaluate the extent to which this correlation is affected by repeated standing phases. STUDY DESIGN/SAMPLE: This is an observational cohort study. PATIENT SAMPLE: A total of 410 asymptomatic subjects (non-athletes), 21 asymptomatic soccer players (athletes), and 176 patients with low back pain (LBP) were included. OUTCOME MEASURES: The correlation between sacrum orientation (SO) and LL was determined in six repetitive upright standing postures. MATERIALS AND METHODS: A non-invasive strain-gauge based measuring system was used. RESULTS: Back-shape measurements yielded a similar correlation to that measured in previous X-ray examinations. The coefficient of determination (R2) between SO and LL ranged between 0.76 and 0.79 for the asymptomatic cohort. Athletes showed the strongest correlation (0.76<=R2<=0.84). For patients with LBP, the correlation substantially decreased (0.18<=R2<=0.39). R2 was not strongly affected by repeated standing phases. CONCLUSIONS: The correlation between SO and LL can be assessed by surface measurements of the back shape and is not influenced by natural variations in the standing posture. PMID- 29174458 TI - Anterior cement augmentation of adjacent levels after vertebral body replacement leads to superior stability of the corpectomy cage under cyclic loading-a biomechanical investigation. AB - BACKGROUND: In the operative treatment of osteoporotic vertebral body fractures, a dorsal stabilization in combination with a corpectomy of the fractured vertebral body might be necessary with respect to the fracture morphology, whereby the osteoporotic bone quality may possibly increase the risk of implant failure. To achieve better stability, it is recommended to use cement-augmented screws for dorsal instrumentation. Besides careful end plate preparation, cement augmentation of the adjacent end plates has also been reported to lead to less reduction loss. PURPOSE: The aim of the study was to evaluate biomechanically under cyclic loading whether an additional cement augmentation of the adjacent end plates leads to improved stability of the inserted cage. STUDY DESIGN/SETTING: Methodical cadaver study. MATERIALS AND METHODS: Fourteen fresh frozen human thoracic spines with proven osteoporosis were used (T2-T7). After removal of the soft tissues, the spine was embedded in Technovit (Kulzer, Germany). Subsequently, a corpectomy of T5 was performed, leaving the dorsal ligamentary structures intact. After randomization with respect to bone quality, two groups were generated: Dorsal instrumentation (cemented pedicle screws, Medtronic, Minneapolis, MN, USA)+cage implantation (CAPRI Corpectomy Cage, K2M, Leesburg, VA, USA) without additional cementation of the adjacent endplates (Group A) and dorsal instrumentation+cage implantation with additional cement augmentation of the adjacent end plates (Group B). The subsequent axial and cyclic loading was performed at a frequency of 1 Hz, starting at 400 N and increasing the load within 200 N after every 500 cycles up to a maximum of 2,200 N. Load failure was determined when the cages sintered macroscopically into the end plates (implant failure) or when the maximum load was reached. RESULTS: One specimen in Group B could not be clamped appropriately into the test bench for axial loading because of a pronounced scoliotic misalignment and had to be excluded. The mean strength for implant failure was 1,000 N+/-258.2 N in Group A (no cement augmentation of the adjacent end plates, n=7); on average, 1,622.1+/ 637.6 cycles were achieved. In Group B (cement augmentation of the adjacent end plates, n=6), the mean force at the end of loading was 1,766.7 N+/-320.4 N; an average of 3,572+/-920.6 cycles was achieved. Three specimens reached a load of 2,000 N. The differences between the two groups were significant (p=.006 and p=.0047) regarding load failure and number of cycles. CONCLUSIONS: Additional cement augmentation of the adjacent end plates during implantation of a vertebral body replacement in osteoporotic bone resulted in a significant increased stability of the cage in the axial cyclic loading test.

PURPOSE: The present study aims to describe the prognosis and prognostic factors in primary care patients with low back-related leg pain and sciatica. STUDY DESIGN: This is a prospective cohort study. PATIENT SAMPLE: The present study included adults visiting their family doctor with back-related leg pain in the United Kingdom. OUTCOME MEASURES: Information about pain, function, psychological, and clinical variables, was collected. Good outcome was defined as 30% or more reduction in disability (Roland-Morris Disability Questionnaire). METHODS: Participants completed the questionnaires, underwent clinical assessments, received a magnetic resonance imaging scan, and were followed-up 12 months later. Mixed-effects logistic regression evaluated the prognostic value of six a priori defined variable sets (leg pain duration, pain intensity, neuropathic pain, psychological factors, clinical examination, and imaging variables). A combined model, including variables from all models, examined independent effects. The National Institute for Health Research funded the study. There are no conflicts of interest. RESULTS: A total of 609 patients were included. At 12 months, 55% of patients improved in both the total sample and the sciatica group. For the whole cohort, longer leg pain duration (odds ratio [OR] 0.41; confidence interval [CI] 0.19-0.90), higher identity score (OR 0.70; CI 0.53-0.93), and patient's belief that the problem will last a long time (OR 0.27; CI 0.13-0.57) were the strongest independent prognostic factors negatively associated with improvement. These last two factors were similarly negatively associated with improvement in the sciatica subgroup. CONCLUSIONS: The present study provides new evidence on the prognosis and prognostic factors of back related leg pain and sciatica in primary care. Just over half of patients improved at 12 months. Patient's belief of recovery timescale and number of other symptoms attributed to the pain are independent prognostic factors. These factors can be used to inform and direct decisions about timing and intensity of available therapeutic options. PMID- 29174460 TI - Long-term outcomes of transforaminal lumbar interbody fusion in patients with spinal stenosis and degenerative scoliosis. AB - BACKGROUND CONTEXT: Patients with spinal deformity may present with complaints related to either the deformity itself or the manifestations of the coexisting spinal stenosis. There are reports of successful management of lumbar pathology in the absence of global sagittal or coronal imbalance, with limited decompression and fusion, addressing only the symptomatic segment. PURPOSE: Our study examined the long-term outcomes of transforaminal lumbar interbody fusion (TLIF), a less extensive procedure, based on the experience of the senior author over the past 10 years. STUDY DESIGN/SETTING: This was a retrospective study of symptomatic lumbar spinal stenosis and spinal deformity managed by one surgeon at The Cleveland Clinic since 2003. PATIENT SAMPLE: Forty-one patients were included in the study. OUTCOME MEASURES: The present study measures the long-term clinical functional outcomes of these patients through EQ-5D (EuroQol five dimensions questionnaire), PHQ-9 (Patient Health Questionnaire), and PDQ (Pain Disability Questionnaire) forms, along with documented radiographic parameters and Charlson Comorbidity Index (CCI). METHODS: There were no funding or potential conflicts of interest associated biases in the present study. Patients with symptomatic lumbar spinal stenosis with neutral global alignment in the sagittal and coronal planes and symptomatic stenosis at the deformity level were treated by limited fusion and TLIF, and had a follow-up period of at least 5 years. Excluded were patients under 18 years of age, had more than three levels of fusion, and had an active spinal malignancy or recent spinal trauma. The grouping variables were curve magnitude, revision surgeries, and TLIF levels. Clinical outcomes were compared in all the grouping variables. Analysis of variance (ANOVA) and chi-square tests were utilized; p<.05 was considered statistically significant. RESULTS: The average age and follow-up period were 66+/-10 and 7.5 years, respectively. There was no statistical difference between patients with curves measuring between 10 degrees and 20 degrees and greater than 20 degrees for EQ-5D, PHQ-9, and PDQ. Patients had worse PDQ data with larger curves compared with smaller curves at both 5 years and final follow-up. Although there was no statistical significance between preoperative coronal curve magnitude and revision surgeries, patients with curves greater than 20 degrees had higher rates of revision surgeries (75%; p=.343) in the global lumbar curve deformity group. Although there was no statistical significance for patients who underwent revision surgeries,those patients had low PHQ-9 values at the final follow-up (p=.09). The revision surgery rate was 48% in one-level TLIF and 18% in two-level TLIF. Moderate pain disability scores were noticed for one-level TLIF patients (mean=75) compared with two-level TLIF patients (mean=27) at the final follow-up, and approached statistical significance in this comparison (p=.06). CONCLUSION: Although this topic has a limited audience to spinal deformity surgeons, the prevalence of patients who present with adult spinal deformities has been increasing. Short segment fusion, in the setting of modest spinal deformity, is a reasonable and safe option. Further study on the concept of short segment fusions in the growing patient population is required as more comprehensive fusions do have noted complication rates, and a compromise must be reached between the extent of surgery that is enough to provide pain relief and disability and the degree of surgery that is too much to be tolerated in terms of complication rates. PMID- 29174461 TI - Multivariate optimization of solvent bar microextraction combined with HPLC-UV for determination of trace amounts of vincristine in biological fluids. AB - In the current work, an efficient method named solvent bar microextraction-high performance liquid chromatography-UV detection (HPLC-UV) was developed for preconcentration and determining the trace amount of vincristine (VCR) in biological samples such as plasma and urine. Briefly, VCR was extracted from an aqueous sample with pH 10.7 (donor phase) into 1-octanol as the supported liquid membrane (SLM) which is inserted into the pores of the hollow fiber and followed by back extraction into an aqueous receiving phase (pH=3.1). Studying the factors affecting the extraction performance in order to achieve a high extraction efficiency, requires the design of experiments (DOE) approach. In this regards, diverse factors' effects including the pH value of donor and acceptor phases, extraction time, extraction temperature, stirring rate and salt content of the donor phase were considered. The optimum experimental condition was as following: pH of the source phase, 10.7; pH of the receiving phase, 3.1; stirring rate, 1000rpm; extraction temperature, 51 degrees C; extraction time, 60min and 11.3% w/v NaCl in the sample solution. Under the optimal; extraction condition, a favorable preconcentration factor equal to 98.5 was achieved. The linearity range was obtained in the domain of 0.05-5mgL-1. The limits of detection and quantification were 0.015 and 0.05mgL-1. Within-day and between-day RSDs of the proposed SBME method were 4.1% and 12.5%, respectively. Finally, the applicability of the implemented SBME method was evaluated by the extraction and quantification of VCR from biological samples such as urine and plasma and satisfactory results were obtained. PMID- 29174462 TI - Critical Care and Personalized or Precision Medicine: Who needs whom? AB - The current paradigm of modern healthcare is a reactive response to patient symptoms, subsequent diagnosis and corresponding treatment of the specific disease(s). This approach is predicated on methodologies first espoused by the Cnidean School of Medicine approximately 2500years ago. More recently escalating healthcare costs and relatively poor disease treatment outcomes have fermented a rethink in how we carry out medical practices. This has led to the emergence of "P-Medicine" in the form of Personalized and Precision Medicine. The terms are used interchangeably, but in fact there are significant differences in the way they are implemented. The former relies on an "N-of-1" model whereas the latter uses a "1-in-N" model. Personalized Medicine is still in a fledgling and evolutionary phase and there has been much debate over its current status and future prospects. A confounding factor has been the sudden development of Precision Medicine, which has currently captured the imagination of policymakers responsible for modern healthcare systems. There is some confusion over the terms Personalized versus Precision Medicine. Here we attempt to define the key differences and working definitions of each P-Medicine approach, as well as a taxonomic relationship tree. Finally, we discuss the impact of Personalized and Precision Medicine on the practice of Critical Care Medicine (CCM). Practitioners of CCM have been participating in Personalized Medicine unknowingly as it takes the protocols of sepsis, mechanical ventilation, and daily awakening trials and applies it to each individual patient. However, the immediate next step for CCM should be an active development of Precision Medicine. This developmental process should break down the silos of modern medicine and create a multidisciplinary approach between clinicians and basic/translational scientists. PMID- 29174463 TI - Critical care of tropical disease in low income countries: Report from the Task Force on Tropical Diseases by the World Federation of Societies of Intensive and Critical Care Medicine. AB - Tropical disease results in a great burden of critical illness. The same life saving and supportive therapies to maintain vital organ functions that comprise critical care are required by these patients as for all other diseases. In low income countries, the little available data points towards high mortality rates and big challenges in the provision of critical care. Improving critical care in low income countries requires a focus on hospital design, training, triage, monitoring & treatment modifications, the basic principles of critical care, hygiene and the involvement of multi-disciplinary teams. As a large proportion of critical illness from tropical disease is in low income countries, the impact and reductions in mortality rates of improved critical care in such settings could be substantial.

AB - We report on two novel mtDNA mutations in patients affected with mitochondrial myopathy. The first patient, a 44-year-old woman, had bilateral eyelid ptosis and the m.8305C>T mutation in the MTTK gene. The second patient, a 56-year-old man, had four-limb muscle weakness and the MTTM gene m.4440G>A mutation. Muscle biopsies in both patients showed ragged red fibers and numerous COX-negative fibers as well as a combined defect of complex I, III and IV activities. The two mutations were heteroplasmic and detected only in muscle tissue, with a higher mutation load in COX-negative fibers. Additionally, both mutations occurred in highly conserved mt-tRNA sites, and were not found by an in silico search in 30,589 human mtDNA sequences. Our report further expands the mutational and phenotypic spectrum of diseases associated with mutations in mitochondrial tRNA genes and reinforces the notion that mutations in mitochondrial tRNAs represent hot spots for mitochondrial myopathies in adults. PMID- 29174469 TI - Boundary cap cells in development and disease. AB - Broad plasticity of the peripheral glia is an emerging concept during development of the peripheral nervous system (PNS). Recent studies have identified the neural crest-derived boundary caps (BCs), as a multitask stem cell population of the developing PNS. BC progeny migrate along the nerves to provide the major glial component of nerve roots and nerve terminals in the skin. Strikingly, those two locations constitute the privileged sites for development of benign peripheral nerve sheath tumors called neurofibromas in patients with neurofibromatosis type 1 (NF1), making BCs attractive candidates for the 'cell of origin' of this disease. Here, we review these exciting findings, focusing on the origin and novel functions of BCs. We further discuss the heterogeneity of BCs, and address their implication in the pathogenesis of NF1. PMID- 29174470 TI - Associations Between Prostate Volume and Oncologic Outcomes in Men Undergoing Focal Cryoablation of the Prostate. AB - INTRODUCTION: The purpose of this study was to assess the relationship of total prostate volume (TPV) and oncologic outcomes following focal prostate cryoablation. MATERIALS AND METHODS: A query of the Cryo On-Line Database (COLD) registry for men who underwent primary focal prostate cryoablation revealed 829 patients with complete data. The impact of TPV on oncologic outcomes including progression-free survival (PFS) and post-cryoablation biopsy outcome was assessed using Kaplan-Meier curves and Cox and logistic regression models. RESULTS: The median follow-up time was 25.2 months (interquartile range [IQR], 12.7-48.2 months). The median age at time of treatment was 68 years (IQR, 63-74 years) with median prostate-specific antigen (PSA) 5.6 ng/mL (IQR, 4.4-7.5 ng/mL), and median TPV 35 mL (IQR, 26.5-46 mL). PFS was achieved in 83.2%, with positive post cryoablation biopsy detected in 81 (35.7%) of 228 patients. Higher TPV was associated with higher biochemical progression (BP) using the Phoenix definition (39 vs. 34.5 mL; P = .003) and was an independent predictor of BP (hazard ratio, 1.01; P = .02). Conversely, men who had a positive post-cryoablation biopsy had significantly smaller median TPV on univariate and multivariate analyses (31 vs. 39 mL; P < .001), (odds ratio, 0.97; P = .001), respectively. Higher median pretreatment PSA density was associated with higher BP (0.18 vs. 0.16; P = .005) and positive post-cryoablation biopsy rates (0.2 vs. 0.16; P = .003). CONCLUSION: Prostate volume has contradictory effects on BP and post-cryoablation biopsy outcome in men who underwent primary focal prostate cryoablation. Remnant viable tissue in larger prostates continues to produce more PSA over time, which may impact BP. This may raise the need to develop a new definition for oncologic success following focal gland therapy rather than the American Society for Radiation Oncology (ASTRO) and Phoenix definitions. PMID- 29174471 TI - Oncologic Outcomes of Partial Nephrectomy for Stage T3a Renal Cell Cancer. AB - BACKGROUND: Partial nephrectomy (PN) for clinical stage T3 tumors is controversial. Radical nephrectomy (RN) has been associated with a greater rate of chronic kidney disease, an increased risk of cardiovascular disease, and increased mortality compared with PN. We present our long-term 2-center experience with PN for stage pT3a tumors and compare the oncologic outcomes with those of similar patients treated with RN. MATERIALS AND METHODS: We reviewed the data from all patients who had undergone nephrectomy for renal cell carcinoma from 1987 to 2015 in 2 medical centers. The study included 134 patients with pathologic stage T3a tumors, of whom 48 and 86 underwent PN and RN, respectively. We compared the 2 groups (PN and RN) using univariate and multivariate analyses. RESULTS: The tumors of all patients with pathologic stage T3a who had undergone PN had been pathologically upstaged from clinical stage T1 or T2. Univariate and multivariate analyses revealed tumor size was significantly different statistically between the study groups (median, 7.0 cm in RN group vs. 4.0 cm in PN group; P < .001). Surgery type was not a predictor of local recurrence (P = .978), metastatic progression (P = .972), death from renal cancer (P = .626), or death from all causes (P = .974) at the 5-year follow-up point. CONCLUSION: The results of the present study have shown similar oncologic outcomes between 48 patients with stage pT3a renal cancer who underwent PN and 86 patients who underwent RN. Although PN was not performed on clinical T3a tumors, our findings suggest that PN can also be considered for these tumors and, thus, avoid the long term complications of RN. However, strict follow-up protocols are mandatory. PMID- 29174472 TI - The influence of biodegradable magnesium implants on the growth plate. AB - : Mg-based biodegradable materials are considered promising candidates in the paediatric field due to their favourable mechanical and biological properties and their biodegrading potential that makes a second surgery for implant removal unnecessary. In many cases the surgical fixation technique requires a crossing of the growth plate by the implant in order to achieve an adequate fragment replacement or fracture stabilisation. This study investigates the kinetics of slowly and rapidly degrading Mg alloys in a transphyseal rat model, and also reports on their dynamics in the context of the physis and consecutive bone growth. Twenty-six male Sprague-Dawley rats received either a rapidly degrading (ZX50; n = 13) or a slowly degrading (WZ21; n = 13) Mg alloy, implanted transphyseal into the distal femur. The contralateral leg was drilled in the same manner and served as a direct sham specimen. Degradation behaviour, gas formation, and leg length were measured by continuous in vivo micro CT for up to 52 weeks, and additional high-resolution uCT (HRS) scans and histomorphological analyses of the growth plate were performed. The growth plate was locally destroyed and bone growth was significantly diminished by the fast degradation of ZX50 implants and the accompanying release of large amounts of hydrogen gas. In contrast, WZ21 implants showed homogenous and moderate degradation performance, and the effect on bone growth did not differ significantly from a single drill hole defect. STATEMENT OF SIGNIFICANCE: This study is the first that reports on the effects of degrading magnesium implants on the growth plate in a living animal model. The results show that high evolution of hydrogen gas due to rapid Mg degradation can damage the growth plate substantially. Slow degradation, however, such as seen for WZ21 alloys, does not affect the growth plate more than drilling alone, thus meeting one important prerequisite for deployment in paediatric osteosynthesis. PMID- 29174473 TI - Distribution of cervical metastasis in tongue cancer: Are occult metastases predictable? A retrospective study of 117 oral tongue carcinomas. AB - PURPOSE: The aims of this study were to evaluate the pattern of distribution of cervical metastasis in tongue cancer and to analyze the various therapeutic options available. Moreover, numerous histological features were analyzed to assess the impact of each factor on overall survival. MATERIALS AND METHODS: A retrospective analysis was conducted using the records of patients diagnosed with oral tongue cancer between 2004 and 2010 in the Virgen de las Nieves University Hospital (HUVN). A total of 117 patients with squamous cell carcinoma of the tongue treated with glossectomy and selective neck dissection were included in the study. The pattern of distribution of cervical metastases and numerous histological features such as T-stage, N stage, surgical margins, tumor thickness, extracapsular spread (ECS) and vascular invasion were analyzed. RESULTS: Level IIA was the most affected, followed by level III. The rate of skip metastasis was 7,4%. T and N stage, tumor thickness, ECS, surgical margins and nerve and vascular invasion were associated with poorer outcomes in terms of overall survival (p < 0,001). CONCLUSION: Cervical nodal involvement represents the major prognostic factor in tongue cancer. A total of 51,2% of N+ patients presented T1 and T2 tumors in this series. We recommend performing neck dissection at the early stages in clinically N0 patients when a tumor thickness >0,4 cm is suspected. Level IV should be included in the neck dissection of clinically N0 tongue cancer. PMID- 29174474 TI - Iron overload in hematological disorders. AB - While most common symptom of impairment of iron homeostasis is iron deficiency anemia, some hematological disorders are associated with iron overload (IO). These disorders are related mainly to chronic severe hemolytic anemia, where red blood cells (RBC) or their precursors are destroyed prematurely (hemolyzed), leading to anemia that cannot be compensated by increased production of new RBC. In such cases, IO is mainly due to repeated RBC transfusions and/or increased uptake of iron in the gastrointestinal tract. Normally, iron is present in the plasma and in the cells bound to compounds that render it redox inactive. Iron overload leaves a fraction of the iron free (labile iron pool) and redox active, leading to the generation of excess free radicals such as the reactive oxygen species. This condition upsets the cellular redox balance between oxidants and antioxidants, leading to oxidative stress. The free radicals bind to various cellular components, thereby becoming toxic to vital organs. Oxidative stress may also affect blood cells, such as RBC, platelets and neutrophils, exacerbating the anemia, and causing recurrent infections and thrombotic events, respectively. The toxic effect of IO can be decreased by treating the patients with iron chelators that enter cells, bind free iron and remove it from the body through the urine and feces. Iron toxicity may be also ameliorated by treatment with anti-oxidants that scavenge free radicals and/or correct their damage. The use of iron chelators is widely accepted when started in young patients with severe chronic anemia, but is still debatable as a therapeutic modality for older patients suffering from IO due to myelodysplastic syndromes. It should be noted that in addition to preventing iron toxicity, some compounds with iron chelator activity may also benefit other aspects of hematological disorders. These aspects include stimulation of platelet production, inhibition of leukemic cell proliferation and induction of their differentiation. Compounds with such multiple activities may prove beneficial for at least some patients with leukemia and myelodysplastic syndromes. PMID- 29174475 TI - Temporal trends in the premorbid use of preventive treatments in patients with acute ischemic cerebrovascular events and a history of vascular disease: The Dijon Stroke Registry (1985-2010). AB - INTRODUCTION: Although secondary prevention in patients with arterial vascular diseases has improved, a gap between recommendations and clinical practice may exist. OBJECTIVES: We aimed to evaluate temporal trends in the premorbid use of preventive treatments in patients with ischemic cerebrovascular events (ICVE) and prior vascular disease. METHODS: Patients with acute ICVE (ischemic stroke/TIA) were identified through the population-based stroke registry of Dijon, France (1985-2010). Only those with history of arterial vascular disease were included and were classified into four groups: patients with previous coronary artery disease only (CAD), previous peripheral artery disease only (PAD), previous ICVE only, and patients with at least two different past vascular diseases (polyvascular group). We assessed trends in the proportion of patients who were treated with antihypertensive treatments and antithrombotics at the time of their ICVE using multivariable logistic regression models. RESULTS: Among the 5309 patients with acute ICVE, 2128 had a history of vascular disease (mean age 77.3+/ 11.9, 51% men; 25.1% CAD 7.5% PAD, 39.8% ICVE, and 27.5% poylvascular). A total of 45.8% of them were on antithrombotics, 64.1% on antihypertensive treatment, and 34.4% on both. Compared with period 1985-1993, periods 1994-2002 and 2003 2010 were associated with a greater frequency of prior-to-ICVE use of antithrombotics (adjusted OR=5.94; 95% CI: 4.61-7.65, P<0.01, and adjusted OR=6.92; 95% CI: 5.33-8.98, P<0.01, respectively) but not of antihypertensive drugs. Consistent results were found when analyses were stratified according to the type of history of arterial vascular disease. CONCLUSION: Patients with ICVE and previous vascular disease were still undertreated with recommended preventive therapies. PMID- 29174476 TI - Brown-Sequard syndrome caused by hyperextension in a patient with atlantoaxial subluxation due to an os odontoideum. AB - Brown-Sequard syndrome is an uncommon complication of atlantoaxial arthrodesis. A 50-year-old female visited our emergency department after falling from a ladder. Radiologic evaluations revealed chronic C1-2 instability with acute spinal cord injury. The day after atlantoaxial fusion was performed, she developed left-sided motor weakness and the loss of right-sided pain and temperature sensation. Based on physical examination and radiologic findings, we diagnosed her as having Brown Sequard syndrome. Spine surgeons performing this procedure should therefore consider Brown-Sequard syndrome if a patient displays signs of postoperative hemiplegia. PMID- 29174477 TI - The effect of hip reconstruction on gross motor function levels in children with cerebral palsy. AB - OBJECTIVE: The aim of this study was to determine whether the hip reconstruction has an effect on gross motor function classification system (GMFCS) levels in patients with hip instability in cerebral palsy (CP). METHODS: A total of 45 hips of 30 patients (mean age: 8.7 (4-17) years) with CP operated due to hip instability with a minimum of 2 years of follow-up were included into the study. Migration index was used for classification of the severity of hip instability. Clinical evaluation included sitting and walking ability, existence of pressure sores, difficulty in perineal care, and hip pain. The functional gains from the surgery were evaluated with changes in GMFCS levels. Wilcoxon T test, chi-square test and Spearman correlation test were used. RESULTS: Mean follow-up time was 57 (24-132) months. The distribution of preoperative GMFCS was level I in 1 patient, level II in 4 patients, level III in 5 patients, level IV in 9 patients and level V in 11 patients. The complaints resolved in 25 patients, and persisted in 5 postoperatively. There was no correlation between the changes in GMFCS levels and the postoperative complaints (p = 0.504). The GMFCS levels did not change in 20 patients, improved in 8, and worsened in 2. There were no significant differences between the preoperative and postoperative GMFCS levels (p = 0.052). Positive correlations were found between the preoperative GMFCS-MI, the type of CP-MI respectively (p = 0.001, p = 0.015). CONCLUSION: There was an improvement in preoperative complaints. GMFCS levels remained stable after surgery. Relief in symptoms was not consistent with the changes in GMFCS in children with cerebral palsy after hip reconstruction. LEVEL OF EVIDENCE: Level IV, Therapeutic study. PMID- 29174478 TI - Amygdala Inhibitory Circuits Regulate Associative Fear Conditioning. AB - Associative memory formation is essential for an animal's survival by ensuring adaptive behavioral responses in an ever-changing environment. This is particularly important under conditions of immediate threats such as in fear learning. One of the key brain regions involved in associative fear learning is the amygdala. The basolateral amygdala is the main entry site for sensory information to the amygdala complex, and local plasticity in excitatory basolateral amygdala principal neurons is considered to be crucial for learning of conditioned fear responses. However, activity and plasticity of excitatory circuits are tightly controlled by local inhibitory interneurons in a spatially and temporally defined manner. In this review, we provide an updated view on how distinct interneuron subtypes in the basolateral amygdala contribute to the acquisition and extinction of conditioned fear memories.

PMID- 29174479 TI - Practical implementation, education and interpretation guidelines for continuous glucose monitoring: A French position statement. AB - The use by diabetes patients of real-time continuous interstitial glucose monitoring (CGM) or the FreeStyle Libre(r) (FSL) flash glucose monitoring (FGM) system is becoming widespread and has changed diabetic practice. The working group bringing together a number of French experts has proposed the present practical consensus. Training of professionals and patient education are crucial for the success of CGM. Also, institutional recommendations must pay particular attention to the indications for and reimbursement of CGM devices in populations at risk of hypoglycaemia. The rules of good practice for CGM are the precursors of those that need to be enacted, given the oncoming emergence of artificial pancreas devices. It is necessary to have software combining user-friendliness, multiplatform usage and average glucose profile (AGP) presentation, while integrating glucose and insulin data as well as events. Expression of CGM data must strive for standardization that facilitates patient phenotyping and their follow-up, while integrating indicators of variability. The introduction of CGM involves a transformation of treatment support, rendering it longer and more complex as it also includes specific educational and technical dimensions. This complexity must be taken into account in discussions of organization of diabetes care. PMID- 29174481 TI - A Comparison of Regorafenib and TAS-102 for Metastatic Colorectal Cancer: A Systematic Review and Network Meta-analysis. AB - BACKGROUND: Regorafenib and TAS-102 have shown to be superior to placebo in refractory metastatic colorectal cancer. However, no studies have directly compared both drugs. Giving the lack of standard options in this scenario, a systematic review to compare the efficacy and safety of regorafenib and TAS-102 was performed. MATERIALS AND METHODS: A systematic review using the PubMed, Medline, Embase, Scopus, and Cochrane databases to identify published and unpublished studies up to November 2015 for randomized controlled trials for patients with metastatic colorectal cancer, involving regorafenib or TAS-102, was performed. Data including overall survival, progression-free survival, and toxicity were extracted. Pairwise direct meta-analyses (regorafenib vs. placebo and TAS-102 vs. placebo) and indirect comparison (regorafenib vs. TAS-102) using network meta-analyses methods to preserve randomization were performed using random effects. RESULTS: Three randomized controlled trials fulfilled eligibility criteria (regorafenib monotherapy for previously treated metastatic colorectal cancer [CORRECT]: an international, multicentre, randomised, pacebo-controlled, phase 3 trial, regorafenib plus best supportive care versus placebo plus best supportive care in Asian patients with previously treated metastatic colorectal cancer [CONCUR]: a randomised, double-blind, placebo-controlled, phase 3 trial, and randomized trial of TAS-102 for refractory metastatic colorectal cancer [RECOURSE] trials) involving 1764 patients (regorafenib, 641; TAS-102, 534; placebo, 589). Subgroups of patients (1659) who had not received prior regorafenib or TAS-102 were used to perform meta-analyses for efficacy. In the indirect comparison, no statistically significant differences were observed between regorafenib and TAS-102 in overall survival (hazard ratio, 0.96; 95% confidence interval [CI], 0.57-1.66; P = .91) or progression-free survival (hazard ratio, 0.85; 95% CI, 0.40-1.81; P = .67). However, regorafenib has statistically more all grade any toxicity (risk difference, 0.31; 95% CI, 0.25 0.38; P = .001) compared with TAS-102. Subgroup analysis of adverse events showed a different toxicity profile between both drugs. CONCLUSION: In this indirect comparison, regorafenib and TAS-102 appeared to have similar efficacy. However, regorafenib was associated with more toxicity compared with TAS-102. PMID- 29174482 TI - Re: Follow-up of Prostatectomy Versus Observation for Early Prostate Cancer. PMID- 29174483 TI - How glucocorticoids change life in Duchenne muscular dystrophy. PMID- 29174485 TI - Navigation of Fluorescence Cameras during Soft Tissue Surgery-Is it Possible to Use a Single Navigation Setup for Various Open and Laparoscopic Urological Surgery Applications? AB - PURPOSE: Real-time visualization fluorescence imaging can guide surgeons during tissue resection. Unfortunately tissue induced signal attenuation limits the value of this technique to superficial applications. By positioning the fluorescence camera via a dedicated navigation setup we reasoned that the technology could be made compatible with deeper lesions, increasing its impact on clinical care. Such an impact would benefit from the ability to implement the navigation technology in different surgical settings. For that reason we evaluated whether a single fluorescence camera could be navigated toward targeted lesions during open and laparoscopic surgery. MATERIALS AND METHODS: A fluorescence camera with scopes available for open and laparoscopic procedures was integrated with a navigation platform. Lymph nodes identified on SPECT/CT (single photon emission computerized tomography/computerized tomography) or free hand single photon emission computerized tomography acted as navigation targets and were displayed as augmented overlays in the fluorescence camera video feed. The accuracy of this setup was evaluated in a phantom study of 4 scans per single photon emission computerized tomography imaging modality. This was followed by 4 first in human translations into sentinel lymph node biopsy procedures for penile (open surgery) and prostate (laparoscopic surgery) cancer. RESULTS: Overall the phantom studies revealed a tool-target distance accuracy of 2.1 mm for SPECT/CT and 3.2 mm for freehand single photon emission computerized tomography, and an augmented reality registration accuracy of 1.1 and 2.2 mm, respectively. Subsequently open and laparoscopic navigation efforts were accurate enough to localize the fluorescence signals of the targeted tissues in vivo. CONCLUSIONS: The phantom and human studies performed suggested that the single navigation setup is applicable in various open and laparoscopic urological surgery applications. Further evaluation in larger patient groups with a greater variety of malignancies is recommended to strengthen these results. PMID- 29174484 TI - Long-term effects of glucocorticoids on function, quality of life, and survival in patients with Duchenne muscular dystrophy: a prospective cohort study. AB - BACKGROUND: Glucocorticoid treatment is recommended as a standard of care in Duchenne muscular dystrophy; however, few studies have assessed the long-term benefits of this treatment. We examined the long-term effects of glucocorticoids on milestone-related disease progression across the lifespan and survival in patients with Duchenne muscular dystrophy. METHODS: For this prospective cohort study, we enrolled male patients aged 2-28 years with Duchenne muscular dystrophy at 20 centres in nine countries. Patients were followed up for 10 years. We compared no glucocorticoid treatment or cumulative treatment duration of less than 1 month versus treatment of 1 year or longer with regard to progression of nine disease-related and clinically meaningful mobility and upper limb milestones. We used Kaplan-Meier analyses to compare glucocorticoid treatment groups for time to stand from supine of 5 s or longer and 10 s or longer, and loss of stand from supine, four-stair climb, ambulation, full overhead reach, hand-to-mouth function, and hand function. Risk of death was also assessed. This study is registered with ClinicalTrials.gov, number NCT00468832. FINDINGS: 440 patients were enrolled during two recruitment periods (2006-09 and 2012-16). Time to all disease progression milestone events was significantly longer in patients treated with glucocorticoids for 1 year or longer than in patients treated for less than 1 month or never treated (log-rank p<0.0001). Glucocorticoid treatment for 1 year or longer was associated with increased median age at loss of mobility milestones by 2.1-4.4 years and upper limb milestones by 2.8-8.0 years compared with treatment for less than 1 month. Deflazacort was associated with increased median age at loss of three milestones by 2.1-2.7 years in comparison with prednisone or prednisolone (log-rank p<0.012). 45 patients died during the 10 year follow-up. 39 (87%) of these deaths were attributable to Duchenne-related causes in patients with known duration of glucocorticoids usage. 28 (9%) deaths occurred in 311 patients treated with glucocorticoids for 1 year or longer compared with 11 (19%) deaths in 58 patients with no history of glucocorticoid use (odds ratio 0.47, 95% CI 0.22-1.00; p=0.0501). INTERPRETATION: In patients with Duchenne muscular dystrophy, glucocorticoid treatment is associated with reduced risk of losing clinically meaningful mobility and upper limb disease progression milestones across the lifespan as well as reduced risk of death.

AB - Oviparous mother transfer significant amounts of steroid to egg yolk during oviposition and the amounts may vary throughout the embryonic development. Eggshell may contain steroid hormones and the amounts could be different during embryonic development inside the egg. This study was designed to quantify the steroid concentrations in the eggshells of Japanese quail. We hypothesized that the steroids would be accumulated in the eggshells in a sex-dependent manner. Eggshells were obtained from three different stages (after laying, 15 days of incubation, and after hatching). The internal contents of the shells were carefully removed, completely dried and pulverized. The steroid contents of the eggshells were then measured by RIA. Physiologic variations in steroids were analyzed according to the amounts accumulated in the eggshells with the different embryonic stages. Results indicate that eggshell testosterone concentrations were high after laying. However, the concentrations were decreased during embryonic development and hatching and no difference was found in eggshell testosterone levels between male and female. However, eggshell estradiol concentrations were undetectable at laying time and the amounts were significantly increased at 15 days of incubation and slightly after hatching. Eggshell estradiol levels were significantly high in female eggshells than male during embryonic development. In contrast, eggshell corticosterone levels were significantly higher in males than in females after hatching. These results clearly demonstrated that eggshells accumulated steroid hormones, and the amounts varied during embryonic development concomitant with changes the internal contents of the eggs.

The anterior pituitary is the master gland responsible for growth, reproduction, and metabolism and is regulated by thousands of miRNAs/mRNAs molecules. However, little is known about miRNAs and their relationships with mRNAs in Tibetan minipig anterior pituitary. Using microarray and mRNA-Sequencing, we identified 203 miRNAs and 12,040 mRNA transcripts from the anterior pituitary of Tibetan minipigs. These miRNAs were corresponding to 194 hairpin precursors, 25 miRNA clusters and 24 miRNA families. In addition, 64 intragenic miRNAs were annotated. Using three bioinformatic algorithms (TargetScan, miRanda and RNAhybrid), 359,184 possible miRNA-mRNA interactions were predicted, and an integrated network of miRNAs and pituitary-specific mRNA transcripts was established. To validate the predicted results, the degradome sequencing was employed to confirm miRNA-mRNA interactions, totally, 30 miRNA-mRNA pairs were identified. The present study provided a general overview of miRNA and mRNA annotation in Tibetan minipig anterior pituitary and established a miRNA-mRNA interactions database at the whole genome scale, which helps shed light on the molecular mechanisms in the anterior pituitary of pigs even other mammals.

AB - Micro cultural dynamics are concerned with the mechanisms of transmission, retention, and modification of cultural information in social networks. When interacting individuals mutually recognize that they share psychological reactions to given cultural information, it may be grounded as an aspect of their shared reality under specifiable conditions. The interpretation of cultural information as socially verified shared reality provides a basis for further dissemination of the information and coordinated social action. We review the recent literature that supports this general contention, while highlighting the role of emotion-a somewhat under-recognized aspect of shared reality research-and emphasizing the mediating role of cultural dynamics in the mutual constitution of social reality and shared reality. PMID- 29174490 TI - Risk of Cardiac Events Associated With Antidepressant Therapy in Patients With Long QT Syndrome. AB - Patients with long QT syndrome (LQTS) are at a high risk of cardiac events. Many patients with LQTS are treated with antidepressant drugs (ADs). We investigated the LQTS genotype-specific risk of recurrent cardiac arrhythmic events (CAEs) associated with AD therapy. The study included 59 LQT1 and 72 LQT2 patients from the Rochester-based LQTS Registry with corrected QT (QTc) prolongation and a history of AD therapy. Using multivariate Anderson-Gill models, we estimated the LQTS genotype-specific risk of recurrent CAEs (ventricular tachyarrhythmias, aborted cardiac arrest, or sudden cardiac death) associated with time-dependent ADs. Specifically, we examined the risk associated with all ADs, selective serotonin reuptake inhibitor (SSRI), and ADs classified on the CredibleMeds list (www.CredibleMeds.org) as "Conditional" or "Known risk of Torsades de pointes (TdP)." After adjusting for baseline QTc duration, sex, and time-dependent beta blocker usage, there was an increased risk of recurrent CAEs associated with ADs in LQT1 patients (hazard ratio = 3.67, 95% confidence interval 1.98-6.82, p < 0.001) but not in LQT2 patients (hazard ratio = 0.89, 95% confidence interval 0.49-1.64, p = 0.716; LQT1 vs LQT2 interaction, p < 0.001). Similarly, LQT1 patients who were on SSRIs or ADs with "Known risk of TdP" had a higher risk of recurrent CAEs than those patients off all ADs, whereas there was no association in LQT2 patients. ADs with "Conditional risk of TdP" were not associated with the risk of recurrent CAEs in any of the groups. In conclusion, the risk of recurrent CAEs associated with time-dependent ADs is higher in LQT1 patients but not in LQT2 patients. Results suggest a LQTS genotype-specific effect of ADs on the risk of arrhythmic events. PMID- 29174491 TI - Oxyneurography: A non-invasive NIRS technique to measure nerve oxygenation.

PMID- 29174493 TI - Surgical resection versus transarterial chemoembolization for BCLC intermediate stage hepatocellular carcinoma: a systematic review and meta-analysis. AB - BACKGROUND & OBJECTIVE: Transarterial chemoembolization (TACE) is recommended as the first-line therapy for intermediate stage hepatocellular carcinoma (HCC) according to the Barcelona Clinic Liver Cancer (BCLC) algorithm. However, in clinical practice, many such patients undergo surgical resection. A meta-analysis with a systematic search of the medical literature was conducted to compare these two procedures for BCLC intermediate stage HCC. METHODS: PubMed, Embase, Medline and Cochrane library were searched for studies comparing surgical resection with TACE for BCLC intermediate stage HCC that were published before December 2016. The primary outcome was overall survival, and the secondary outcomes were postoperative complications and 30-day mortality. RESULTS: This meta-analysis included 9 studies with 2619 patients (surgical resection, n = 1204 (46%) and TACE, n = 1415 (54%)). When compared with the TACE group, the pooled hazard ratio (HR) for the 1, 3 and 5-year OS rates in patients who underwent surgical resection were 0.62 (95% CI 0.51-0.75, P = 0.39; I2 = 6%, P < 0.001), 0.58 (95% CI 0.51-0.67, P = 0.25; I2 = 22%, P < 0.001) and 0.59 (95% CI 0.54-0.64, P = 0.18; I2 = 20%, P < 0.001). No significant differences in the pooled odds ratios (OR) were found between surgical resection and TACE in postoperative complications and 30-day mortality [OR 1.23 (95% CI 0.87 to 1.74, P = 0.390; I2 = 0%, P = 0.240) and OR 1.11 (95% CI 0.60 to 2.04, P = 0.89; I2 = 0%, P = 0.740), respectively]. CONCLUSION: This meta-analysis on studies on Asian HCC patients demonstrated surgical resection had better overall survival than TACE for patients with intermediate stage HCC, without any significant increase in postoperative complication or 30-day mortality rates. Further studies are needed to validate these results on Western patients, moreover, a reappraisal of the recommended treatments for BCLC intermediate stage HCC should be considered. PMID- 29174495 TI - Global spread of mouse-adapted Staphylococcus aureus lineages CC1, CC15, and CC88 among mouse breeding facilities. AB - We previously reported that laboratory mice from all global vendors are frequently colonized with Staphylococcus aureus (S. aureus). Genotyping of a snap sample of murine S. aureus isolates from Charles River, US, showed that mice were predominantly colonized with methicillin-sensitive CC88 strains. Here, we expanded our view and investigated whether laboratory mice from other global animal facilities are colonized with similar strains or novel S. aureus lineages, and whether the murine S. aureus isolates show features of host adaptation. In total, we genotyped 230 S. aureus isolates from various vendor facilities of laboratory mice around the globe (Charles River facilities in the USA, Canada, France, and Germany; another US facility) and university- or company-associated breeding facilities in Germany, China and New Zealand. Spa typing was performed to analyse the clonal relationship of the isolates. Moreover, multiplex PCRs were performed for human-specific virulence factors, the immune-evasion cluster (IEC) and superantigen genes (SAg). We found a total of 58 different spa types that clustered into 15 clonal complexes (CCs). Three of these S. aureus lineages had spread globally among laboratory mice and accounted for three quarters of the isolates: CC1 (13.5%), CC15 (14.3%), and CC88 (47.0%). Compared to human colonizing isolates of the same lineages, the murine isolates frequently lacked IEC genes and SAg genes on mobile genetic elements, implying long-term adaptation to the murine host. In conclusion, laboratory mice from various vendors are colonized with host-adapted S. aureus-strains of a few lineages, predominantly the CC88 lineage. S. aureus researchers must be cautioned that S. aureus colonization might be a relevant confounder in infection and vaccination studies and are therefore advised to screen their mice before experimentation. PMID- 29174496 TI - Is it safe for people with epilepsy to donate blood? A systematic review. AB - OBJECTIVE: In many countries people with epilepsy are temporarily or permanently excluded from blood donation. This exclusion is based on the assumption that they are more likely to experience adverse donor reactions such as epileptic seizures, and not on scientific evidence. A systematic review was therefore performed to critically examine the evidence with regard to adverse effects of blood donation on epilepsy patients. METHODS: Five databases (MEDLINE, Embase, The Cochrane Library, Web of Science and CINAHL) were searched for studies from the date of inception until December 2014. Two of the authors screened the articles and extracted the data independently and used the GRADE approach to assess the quality of evidence. RESULTS: The literature search yielded 7283 references. Following title and abstract screening in the first phase, and full text screening in the second phase, only three observational studies were finally withheld: one cohort study and two case series. None of the three studies could demonstrate that a blood donation resulted in adverse events in epilepsy patients. However, the studies were of poor methodological quality and lacked a solid statistical analysis. CONCLUSIONS: Limited low quality studies could not demonstrate that blood donors with epilepsy are at an increased risk of adverse events. Further research is necessary to determine whether and how long epilepsy patients have to be excluded from blood donation. PMID- 29174497 TI - Antioxidant action of grape seed polyphenols and aerobic exercise in improving neuronal number in the hippocampus is associated with decrease in lipid peroxidation and hydrogen peroxide in adult and middle-aged rats. AB - The present study explored the effects of swimming training and grape seed proanthocyanidin extract (GSPE) on neuronal survival in the hippocampus (HC) of middle-aged rats along with oxidative stress (OS) parameters. Further, the bioavailability of the GSPE, catechin, epicatechin and gallic acid were measured in the HC and plasma. Male Wistar rats were grouped into: sedentary control, SE C; swimming trained, SW-T; SE-C, supplemented sedentary, SE-C(PA) and swimming trainees, SW-T(PA). The supplement was a daily dose of 400mg GSPE/kg body weight. Swimming training lasted for 2h/day and for 14weeks. Glutathione level was increased in response to single and combined interventions in the middle-aged rats. Adult trainees showed increased glutathione peroxidase activity unlike middle-aged wherein increase was seen in SE-C(PA) alone. Lowered catalase activity with age in the HC increased in response to the combined interventions although single interventions were also effective. HC from both ages showed decrease in lipid peroxidation and hydrogen peroxide levels in response to the interventions. GSPE constituents were seen in the HC of swimming trained middle aged and adult rats. The study suggests that combined intervention is effective in decreasing LPO and H2O2 generation in the HC. Further, the neuronal numbers and planimetric volumes of CA1 pyramidal layer was significantly reduced in middle-aged rats compared to adults. Interestingly, both interventions enhanced the numbers and volumes in adult and middle-aged rats. Thus, age-associated decrease in CA1 neurons could be restored by both the interventions. The results of the present study will help in developing effective therapies for age associated degenerative changes and cognitive deficits.

At various stages of OneDep data processing, validation reports for three-dimensional structures of biological macromolecules are produced. These reports are based on recommendations of expert task forces representing crystallography, nuclear magnetic resonance, and cryoelectron microscopy communities. The reports provide useful metrics with which depositors can evaluate the quality of the experimental data, the structural model, and the fit between them. The validation module is also available as a stand-alone web server and as a programmatically accessible web service. A growing number of journals require the official wwPDB validation reports (produced at biocuration) to accompany manuscripts describing macromolecular structures. Upon public release of the structure, the validation report becomes part of the public PDB archive. Geometric quality scores for proteins in the PDB archive have improved over the past decade. PMID- 29174499 TI - Preclinical evaluation of a paclitaxel-incorporated nanoparticle-coated balloon in rabbit and porcine models. AB - BACKGROUND: The main drawback of current available drug coated balloons (DCB) is that a certain percentage of the coated drug is lost in the bloodstream during its delivery to the target lesion. We integrated the nanoparticle-mediated drug delivery technology and polydimethylsiloxane (PDMS) as a new excipient to facilitate an efficient drug delivery and uptake by endothelial cells. The present study aimed to evaluate the efficacy of the new DCB. METHOD AND RESULTS: The novel DCB were coated with 5.6mg of paclitaxel-incorporated nanoparticles using PDMS. The efficacy of the new DCB was examined in rabbit iliac stent model (n=12) and in the swine in-stent restenosis model (n=8) by quantitative coronary angiography (QCA) and optical coherence tomography (OCT). At 28days follow-up in the swine in-stent restenosis model, the area stenosis was significantly lower in DCB group as compared with that of the control group in OCT analysis (0.31+/-0.05 vs 0.49+/-0.06, p=0.04) though there was no significant differences observed in the rabbit iliac stent model in QCA and OCT analysis. CONCLUSION: The study results indicated that the paclitaxel-incorporated nanoparticle-coated balloon using PDMS has an inhibitory effect for the proliferation of smooth muscle cell in a swine coronary in-stent restenosis model.

AB - OBJECTIVES: To report long-term results of a novel sirolimus-eluting stent with biodegradable polymer BACKGROUND: Newer generation drug-eluting stents are characterized by thin struts, improved platform design and highly biocompatible polymer carrying the antiproliferative drug. The RapstromTM stent, sharing these features, showed promising outcomes in preclinical models and in a first-in-man trial. METHODS: The present study is a multicenter, non-randomized post-market registry, including patients with de novo coronary artery disease treated with implantation of one or more Rapstrom stents. Primary endpoint of the study was the rate of major adverse cardiac events (MACE) at three-year follow-up. RESULTS: 1073 patients were enrolled, with a high prevalence of diabetes (35%) and acute coronary syndrome at presentation (82%); at three-year follow up, MACE rate was 14.8%, with a low incidence of definite or probable stent thrombosis (0.75%). CONCLUSIONS: These data confirm the good clinical performance of the Rapstrom stent, supporting the concept that the combination of thin struts and biodegradable polymer is associated with positive clinical outcomes. PMID- 29174501 TI - Active Surveillance for Low and Intermediate Risk Prostate Cancer: Opinions of North American Genitourinary Oncology Expert Radiation Oncologists. AB - INTRODUCTION: The ProtecT trial has provided level 1 evidence supporting active surveillance for prostate cancer patients with low-risk and intermediate-risk disease. The effect of these findings on the opinions of North American genitourinary (GU) experts regarding the role of active surveillance for these patients has not been previously examined. MATERIALS AND METHODS: A survey was distributed to 88 practicing North American GU physicians serving on decision making committees of cooperative group research organizations. Questions pertained to appropriateness of active surveillance in patients with low-risk and intermediate-risk (Gleason 3+4) disease. Opinions regarding active surveillance were correlated with practice patterns using Fisher exact test. RESULTS: Forty two radiation oncologists completed the survey. Forty percent had been in practice for more than 20 years; 90% practice at an academic center. Forty-five percent see >= 20 patients per month in consultation. More than 95% (40 of 42) recommended active surveillance for Gleason 6 disease, whereas only 17% recommended active surveillance for Gleason 3+4 disease. There were no demographic differences between supporters or opponents regarding active surveillance with regard to monthly patient volume, practice type, likelihood of self-identifying as an expert brachytherapist, belief in advanced imaging techniques, or preferred default external beam radiation therapy dose/fractionation for either low-risk or intermediate-risk disease. However, there was a trend toward greater support of active surveillance for Gleason 3+4 disease among experts having practiced < 10 years versus >= 10 years (P = .085). CONCLUSION: Active surveillance is almost universally supported by North American GU expert radiation oncologists for low-risk prostate cancer. However, there is very weak support for this strategy in Gleason 3+4 disease despite the ProtecT trial providing level 1 evidentiary support in both risk groups. There were no significant differences between experts supporting versus opposing active surveillance for either low-risk or intermediate-risk disease. These preferences might affect the design of future clinical studies, influencing the adoption of active surveillance in North American clinical practice.

PMID- 29174503 TI - External Validation of the Arterial-Based Complexity Score and First Head-to-Head Comparison With the R.E.N.A.L. and PADUA Scores and C-index. AB - INTRODUCTION: We performed an external validation of the arterial-based complexity (ABC) score using a head-to-head comparison with the R.E.N.A.L. (radius, exophytic/endophytic tumor properties, nearness of tumor to deepest portion of collecting system or sinus, anterior/posterior descriptor, location relative to the polar line), PADUA (preoperative aspects and dimension for anatomic classification of renal tumors), and C-index scores for the prediction of surgical outcomes after partial nephrectomy. MATERIALS AND METHODS: The data from a series of consecutive open or robot-assisted partial nephrectomies performed from January 2014 to July 2016 by 4 expert surgeons at a tertiary academic institution were reviewed. After dedicated training, 1 urologist not involved in the surgical procedures evaluated the cross-sectional imaging studies and assigned the nephrometry score using the 4 nephrometry scoring systems. The predictive performance of the ABC and other scoring systems was tested in univariate and multivariable fashion. RESULTS: Overall, 234 patients were recruited (148 men and 86 women; age, 63 +/- 10.9 years). The scores were all related to the estimated blood loss, use of hilar clamping, ischemia time, operative time, length of stay, and MIC (margin status, ischemia time, complications) score. They were not related to the occurrence of postoperative complications or, for the C-index and ABC score, the length of stay. In a head-to head comparison, the ABC was not inferior only to the C-index relative to the occurrence of complications and MIC score, with borderline statistical significance. On multivariate analysis, the ABC score provided significant improvement only for the prediction of the operative and ischemia times. However, its performance was inferior to that of the other scoring systems. In addition, only the PADUA score improved the prediction of artery clamping and MIC score, and only the R.E.N.A.L. score showed an advantage for the prediction of the estimated blood loss. CONCLUSION: The predictive ability of ABC was inferior to that of well-established existing nephrometry scoring systems, such as the PADUA and R.E.N.A.L. scores. PMID- 29174504 TI - Intravesical Immunomodulatory Imiquimod Enhances Bacillus Calmette-Guerin Downregulation of Nonmuscle-invasive Bladder Cancer. AB - BACKGROUND: The Toll-like receptor (TLR)2/4 agonist bacillus Calmette-Guerin (BCG), although not failure proof, has been the most efficient immunomodulatory treatment of immunogenic nonmuscle-invasive bladder cancer (NMIBC) for > 40 years. We investigated the role of the immunomodulatory molecule TLR7 agonist imiquimod through the BCG key receptors TLR2/4 and the main downstream molecules of the mammalian target of rapamycin pathway in NMIBC treatment. MATERIALS AND METHODS: A total of 40 Fischer-344 rats, 7 weeks old, received 4 doses of 1.5 mg/kg N-methyl-N-nitrosourea intravesically on weeks 0, 2, 4, and 6 for cancer induction. At week 8, the rats were randomized into 4 groups (10 per group) and treated intravesically once a week for 6 weeks: control (0.2 mL of vehicle); BCG (2 * 106 colony-forming units Connaught strain in 0.2 mL); imiquimod (20 mg/kg in 0.2 mL), and associated treatment BCG plus imiquimod in 0.2 mL. The bladders were extracted and analyzed for histopathology, immunohistochemistry, cell proliferation (Ki-67), apoptosis (terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling [TUNEL]), and immunoblotting for TLR2, TLR4, p-P70S6K, and p-4E-BP1 proteins. RESULTS: The histopathology results showed that BCG and imiquimod decreased bladder tumorigenesis compared with the control group, with a proliferation decrease (Ki-67) and an apoptosis increase (TUNEL). BCG upregulated TLR2/4, imiquimod upregulated TLR4, and both downregulated P70S6K1. CONCLUSION: Imiquimod is able to efficiently decrease bladder carcinogenesis through upregulation of TLR7/4 and downregulation of P70S6K1 protein, generating new perspectives to boost BCG effects in the future. PMID- 29174505 TI - Protective effect of quercetin and rutin encapsulated liposomes on induced oxidative stress. AB - Natural antioxidants show many pharmacological properties, but poor solubility and inability to cross cell membrane. Liposomes are biocompatible and phospholipid vesicles able to carry hydrophilic, hydrophobic, and amphiphilic molecules. This paper focus on the synthesis of anionic, cationic and zwitterionic liposomes, loaded with quercetin or rutin, and on the evaluation of their cytotoxicity and protective effects against oxidative stress. Chemical characterization was obtained by dynamic light scattering and z-potential experiments. In vitro cell behavior was evaluated by Neutral Red Uptake test. All liposomes, empty and loaded with antioxidants, are stable. The cytotoxicity of both quercetin and rutin encapsulated in zwitterionic and anionic liposomes is higher than that of their solutions. Quercetin and rutin loaded in cationic liposomes are able to inhibit the toxic effect of empty liposomes. The encapsulation of rutin at 5.0*10-5 and 5.0*10-4M, in zwitterionic and anionic liposomes, protects fibroblasts by H2O2 treatment, while the loading with quercetin does not have effect on improving cell viability. All data suggest that the tested liposomes are stable and able to include quercetin and rutin. The liposomes encapsulation of antioxidants makes easier their internalization by cells. Moreover, zwitterionic and anionic liposomes loaded with rutin protect cells by oxidative stress. Liposomes stability together with their good in vitro cytocompatibility, both empty and loaded with antioxidant molecules, makes these systems suitable candidates as drug delivery systems. Moreover, the encapsulation of rutin, is able to protect cells by oxidative stress. PMID- 29174506 TI - Discovery of novel purine nucleoside derivatives as phosphodiesterase 2 (PDE2) inhibitors: Structure-based virtual screening, optimization and biological evaluation. AB - Phosphodiesterase 2 (PDE2) has received much attention for the potential treatment of the central nervous system (CNS) disorders and pulmonary hypertension. Herein, we identified that clofarabine (4), an FDA-approved drug, displayed potential PDE2 inhibitory activity (IC50 = 3.12 +/- 0.67 MUM) by structure-based virtual screening and bioassay. Considering the potential therapeutic benefit of PDE2, a series of purine nucleoside derivatives based on the structure and binding mode of 4 were designed, synthesized and evaluated, which led to the discovery of the best compound 14e with a significant improvement of inhibitory potency (IC50 = 0.32 +/- 0.04 MUM). Further molecular docking and molecular dynamic (MD) simulations studies revealed that 5'-benzyl group of 14e could interact with the unique hydrophobic pocket of PDE2 by forming extra van der Waals interactions with hydrophobic residues such as Leu770, Thr768, Thr805 and Leu809, which might contribute to its enhancement of PDE2 inhibition. These potential compounds reported in this article and the valuable structure-activity relationships (SARs) might bring significant instruction for further development of potent PDE2 inhibitors.

In this report, a series of N-arylsulfonylsubstituted-1H indole derivatives were designed and synthesized as STAT3 inhibitors, their anti-proliferative activities were evaluated against a number of tumor cells, some potent compounds exhibited IC50 values less than 10 MUM. The most potent compound 4a was further confirmed to inhibit STAT3 phosphorylation at Tyr705. It was further revealed that 4a arrested the cell cycle at the G2/M phase and inhibited tubulin polymerization. This study describes a series of N-arylsulfonylsubstituted-1H indole derivatives as potent anti-cancer agents targeting both STAT3 and tubulin.

PMID- 29174509 TI - TLR8 activation and inhibition by guanosine analogs in RNA: Importance of functional groups and chain length. AB - Toll-like receptor 8 (TLR8) is an important component of the human innate immune system that recognizes single stranded RNA (ssRNA). Recent X-ray crystal structures of TLR8 bound to ssRNA revealed a previously unrecognized binding site for a 5'-UpG-3' dinucleotide. Here we use an atomic mutagenesis strategy coupled with a cellular TLR8 activation assay to probe the importance of specific functional groups present on the guanine base in RNA-mediated receptor agonism and antagonism. Results from RNA analogs containing 7-deazaguanosine, 2 aminopurine and inosine confirm the importance of guanine N7, O6 and N2, respectively, in TLR8 activation. Nevertheless, these RNAs each retained TLR8 antagonism activity. RNA containing 7-deaza-8-azainosine (7d8aI) was prepared from a novel phosphoramidite and found to be a weaker TLR8 activator than guanosine-containing RNA. However, 7d8aI-containing RNA also retained TLR8 antagonism activity indicating that removal of multiple TLR8 H-bonding sites on guanine is insufficient for blocking TLR8 antagonism by guanine-containing RNA. We also identified an oligoribonucleotide length dependence on both TLR8 activation and antagonism. These studies extend our understanding of the effects of nucleobase modification on immune stimulation and will inform the design of novel RNA-based therapeutics.

When fitness categories are established in quartiles or quintiles based on the peak exercise capacity achieved, the association is graded. Although significant health benefits of increased cardiorespiratory fitness (CRF) have been uniformly reported, the degree of protection has varied substantially between studies. This variability is likely due to varying methods used to define CRF categories, and not considering age, despite its strong effect on CRF. To ameliorate these methodological discrepancies, we propose standardized guidelines by which age specific CRF categories should be defined.

AB - The wide anthropogenic use of selenium compounds represents the major source of selenium pollution worldwide, causing environmental issues and health concerns. Microbe-based strategies for metal removal/recovery have received increasing interest thanks to the association of the microbial ability to detoxify toxic metal/metalloid polluted environments with the production of nanomaterials. This study investigates the tolerance and the bioconversion of selenite (SeO32-) by the aerobically grown Actinomycete Rhodococcus aetherivorans BCP1 in association with its ability to produce selenium nanoparticles and nanorods (SeNPs and SeNRs). The BCP1 strain showed high tolerance towards SeO32- with a Minimal Inhibitory Concentration (MIC) of 500mM. The bioconversion of SeO32- was evaluated considering two different physiological states of the BCP1 strain, i.e. unconditioned and/or conditioned cells, which correspond to cells exposed for the first time or after re-inoculation in fresh medium to either 0.5 or 2mM of Na2SeO3, respectively. SeO32- bioconversion was higher for conditioned grown cells compared to the unconditioned ones. Selenium nanostructures appeared polydisperse and not aggregated, as detected by electron microscopy, being embedded in an organic coating likely responsible for their stability, as suggested by the physical-chemical characterization. The production of smaller and/or larger SeNPs was influenced by the initial concentration of provided precursor, which resulted in the growth of longer and/or shorter SeNRs, respectively. The strong ability to tolerate high SeO32- concentrations coupled with SeNP and SeNR biosynthesis highlights promising new applications of Rhodococcus aetherivorans BCP1 as cell factory to produce stable Se nanostructures, whose suitability might be exploited for biotechnology purposes.

AB - The potential of microbial processes for removal of major nutrients (e.g., N, P) and inorganic cations (e.g., Ca2+, Mg2+, and Fe2+) from hydroponic systems was investigated. Microbial consortium- and axenic culture-based experiments were conducted in a waste nutrient solution (WNS). A microbial consortium grown in the WNS and selected microalgae species of Paracercomonas saepenatans were inoculated in two different synthetic media (Bold's Basal Medium (BBM) and synthetic WNS) in batch systems, and the microbial growth characteristics and the rate and extent of nutrient removal were determined for each system. No toxicity or growth inhibition was observed during microbial growth in either media. Both the waste nutrient-grown microbial consortium and Paracercomonas saepenatans can be grown effectively in BBM and WNS, and both remove most ions from both media (e.g.,>99% removal of NO3- and 41-100% removal of PO43-) within 16days. Significant nutrient removal was observed during the growth phase of the microbial communities (4 10days period), indicating major nutrient utilization for microbial growth as well as chemical mineral precipitation. Furthermore, MINEQL+4.6 modeling showed higher PO43- removal in WNS during microbial growth (compared to BBM) due to precipitation of phosphate minerals (e.g., hydroxyapatite, vivianite). The dominant microbial species in both systems were also identified. DNA sequencing showed that Vorticella (58%) and Scenedesmus (33%) in WNS and Scenedesmus (89%) in BBM were the predominant species. This study demonstrates the potential application of microbial consortium (predominantly algae and protozoan)-based treatment techniques for hydroponic systems.

AB - Multispectral images of clothing targets shot at seven different distances (from 10 to 220cm) were recorded at 18 specific wavelengths in the 400-1000nm range to visualize the gunshot residue (GSR) pattern. Principal component analysis (PCA) showed that the use of violet-blue wavelengths (430, 450 and 470nm) provided the largest contrast between the GSR particles and the white cotton fabric. Then, the correlation between the amount of GSR particles on clothing targets and the shooting distance was studied. By selecting the blue frame of multispectral images (i.e. the blue frame in the red-green-blue (RGB) system which falls at 470nm), the amount of pixels containing GSR particles was accounted based on the intensity of pixels in that frame. Results demonstrated that the number of pixels containing GSR exponentially decreases with the shooting distance from 30 to 220cm following a particular exponential equation. However, the targets shot at the shortest distance (10cm) did not satisfy the above equation, probably due to the noticeable differences of the GSR-pattern of these targets (e.g. high presence of soot). Then, the equation was applied to validation samples to estimate the shooting distances, obtaining results with an error below 10%.

AB - Methods to quickly purify methamphetamine hydrochloride from the cutting agent dimethyl sulfone for subsequent identification of confiscated crystalline samples using infrared absorption spectroscopy were compared and evaluated. Although sequential solvation and reprecipitation methods were simple, spectral contamination from dimethyl sulfone was inevitable and might affect the interpretation of the spectra. In addition, methamphetamine hydrochloride and dimethyl sulfone could form a solid solution because of solvation of both crystals into a single solution layer. By contrast, sublimation was an effective method for separation of methamphetamine hydrochloride and dimethyl sulfone. Sublimation combined with infrared absorption spectroscopy enabled rapid identification of crystalline methamphetamine hydrochloride.

PMID- 29174517 TI - Longitudinal associations of the alternative and terminal pathways of complement activation with adiposity: The CODAM study. AB - OBJECTIVE: To investigate longitudinal associations of components of the alternative (C3, C3a, Bb, factor D [FD], factor H [FH], and properdin) and the terminal complement pathway (C5a, sC5b-9) with adiposity. METHODS: A prospective human cohort study (n=574 at baseline, n=489 after 7 years follow-up) was analyzed. Generalized estimating equations were used to evaluate the longitudinal associations between complement components (standardized values) and adiposity (main outcome BMI [kg/m2]). Multiple linear regression models were used to investigate the associations between change in complement levels and change in BMI. Analyses were adjusted for age, sex, medication and lifestyle. RESULTS: Over the 7-year period, baseline C3 was positively associated with BMI (beta=1.72 [95% confidence interval (CI): 1.35; 2.09]). Positive associations were also observed for C3a (beta=0.64 [0.31; 0.97]), FD (beta=1.00 [0.59; 1.42]), FH (beta=1.17 [0.82; 1.53]), and properdin (beta=0.60 [0.28; 0.92]), but not for Bb, C5a or sC5b-9. Moreover, changes in C3 (beta=0.52 [0.34; 0.71]) and FH (beta=0.51 [0.32; 0.70]) were significantly associated with changes in BMI. CONCLUSIONS: The complement system, particularly activation of the alternative pathway, may be involved in development of adiposity. Whether individual aspects of alternative pathway activation have a causal role in human obesity, remains to be investigated.

PMID- 29174519 TI - Importance of sentinel lymphatic node biopsy in detection of early micrometastases in patients with cutaneous squamous cell carcinoma. AB - BACKGROUND: Cutaneous squamous cell carcinoma (CSCC) is the second most common malignant skin cancer with a tendency to spread through the lymphogenic pathway. Metastases are found in 2-6% of cases. The aim of this study was to determine CSCC micrometastases when non-invasive examination methods do not detect them. METHOD: A total of 88 patients were included in the study with clinically diagnosed, histologically confirmed CSCC and no distant or regional lymph node metastases detected during instrumental tests. The patients were grouped into low and high-risk CSCC groups. They underwent one-stage surgery - radical tumour excision and sentinel lymph node/nodes biopsy (SLNB). Significance level of 0.05 was chosen for testing statistical hypotheses. RESULTS: One hundred and fifty three sentinel lymph nodes (SLNs) were detected and excised in 88 patients. Micrometastases were found in five SLNs of three patients with high-risk CSCC. The rate of micrometastases was 3.4%; however, in the high-risk group it was 6.5%. The mean diameter of CSCC with micrometastases in SLN was 5.6 +/- 3.5 cm, and that without micrometastases was 1.5 +/- 1.1 cm (p = 0.003). The depth of CSCC according to Breslow in the patients with detected micrometastases in SLN was 3.5 +/- 1.2 mm, and that without detected micrometastases was 2.2 +/- 1.4 mm (p = 0.047). Patients with micrometastases in sentinel lymphatic nodes underwent radical lymphadenectomy. There was neither recurrence of CSCC metastases in regional lymph nodes nor distant metastases during the research period detected. CONCLUSIONS: In patients with CSCC the rate of micrometastases directly correlates with the depth and diameter of the tumour. In patients with high-risk CSCC the rate of micrometastases is 6.5%.

AB - Although it has been shown that muscle sympathetic nerve activity increases during high altitude exposure, mechanisms of sympathoexcitation and blood pressure control after return from altitude are not well described. We hypothesized that: (1) living for 12days at 4300m (Pikes Peak, Colorado) would result in increased muscle sympathetic nerve activity 24h after return to sea level; (2) post-Pikes Peak sympathetic neural and hemodynamic responses to orthostasis would be decreased due to a potential 'ceiling effect' on sympathetic activity; and (3) the magnitude of individual increases in sympathetic nerve activity post-Pikes Peak would be inversely related to baseline sympathetic nerve activity before traveling to altitude. Muscle sympathetic nerve activity, heart rate and blood pressure were measured in 9 healthy individuals (24+/-8years) in supine, 30 degrees and 45 degrees head-up tilt positions. Measurements were conducted twice at sea level, once before (pre-Pikes Peak) a 12day residence at 4300m, and once within 24h of return (post-Pikes Peak). Supine muscle sympathetic nerve activity was higher (post: 27+/-5 vs pre: 17+/-6bursts/min) upon return from altitude (p<0.05). Individual values for pre-Pikes Peak sympathetic activity were inversely related to post-altitude sympathoexcitation (r=-0.69, p<0.05). There were no differences in neural or cardiovascular responses to tilt between pre and post- Pikes Peak (p>0.05). We conclude that 12days' residence at 4300m causes a sustained sympathoexcitation which does not impair the ability of muscle sympathetic nerves to respond appropriately to orthostasis. PMID- 29174520 TI - Liver Dysfunction during Pregnancy and Its Association of With Preterm Birth in China: A Prospective Cohort Study. AB - BACKGROUND: Liver dysfunction is common in pregnancy but its association with adverse pregnancy outcomes such as preterm birth (PTB) remains unclear. METHODS: A prospective cohort of HBV-infected or uninfected pregnant women attending antenatal care was recruited at Nantong Maternal and Child Health Hospital between January 1, 2012, and June 30, 2016. Liver function tests (LFTs) were monitored through pregnancy. The primary outcomes were PTB and very PTB (delivery prior 37 and 32weeks' gestation respectively). Poisson regression was used to estimate adjusted risk ratios (RR) for women with HBV infection and LFT abnormalities. RESULTS: Among 36,755 pregnant women (1,113 HBV carriers and 35,642 non-HBV subjects), 3,519 (9.57%) had abnormal LFTs. The commonest cause for liver dysfunction during pregnancy was non-alcoholic fatty liver diseases (NAFLD, 51.3%). Abnormal aspartate aminotransferase (AST), gamma glutamyltransferase (GGT) and two folds upper limit of normal total bilirubin (RR and 95%CI: 2.73, 1.30-5.76; 2.24, 1.35-3.31; 2.01, 1.22-3.31 respectively), rather than HBsAg positivity, were identified as independent risk factors for preterm birth. Besides, GGT abnormality was associated with increased risk of very PTB. CONCLUSIONS: We suggest that surveillance of LFTs among pregnant women should be warranted, given the increased risk of PTB.

The SILVER-AP and BRONCE-AP studies]. AB - OBJECTIVES: To determine the clinical characteristics and management of patients with non-valvular atrial fibrillation (NVAF) treated with direct oral anticoagulants (DOAC) according to who initiates their prescription, the Primary Care (PC) physician or referring the patient to a specialist. MATERIAL AND METHODS: Two observational, cross-sectional and multicentre studies were compared for this purpose. The SILVER-AP study was performed in those autonomous communities in which the PC physician can prescribe DOAC directly, and the BRONCE AP study in those autonomous communities in which the PC physician has to refer the patient to the specialist to start treatment with DOAC. Patients on chronic treatment with anticoagulants, in whom therapy was changed, and those that were on current treatment with DOAC for at least 3months, were included. RESULTS: A total of 1,036 patients (790 from SILVER-AP study and 246 from BRONCE-AP study) were included. Compared with the BRONCE-AP study, those patients included in SILVER-AP were older and had more comorbidities, as well as a higher thromboembolic and haemorrhagic risk (CHA2DS2-VASc 4.3+/-1.6 vs. 3.8+/-1.8; P<.001; HAS-BLED 2.1+/-0.8 vs. 1.8+/-1.0; P<.001). Therapeutic adherence and satisfaction with treatment were high. Low doses of DOAC were frequently prescribed, particularly with dabigatran. CONCLUSIONS: Those patients in whom the PC physician can prescribe DOAC directly have a worse clinical profile, as well as a higher thromboembolic and haemorrhagic risk than those patients in whom the PC physician has to refer to the specialist. PMID- 29174523 TI - Transvenous Coil Embolization for the Treatment of Carotid Cavernous Fistula after Pipeline Placement: A Case Report. AB - The Pipeline embolization device (PED), a type of flow diverter, has become an appealing alternative treatment option for large or giant and wide-necked intracranial aneurysms. Carotid cavernous fistula (CCF) resulting from delayed aneurysmal rupture is a rare complication of PED placement with unknown pathophysiology. Here, we describe a case of CCF resulting from aneurysmal rupture following PED placement, and present the details of treatment by transvenous coil embolization. An 81-year-old woman was referred to our hospital for treatment of an 18.0 * 10.3 mm intracranial aneurysm located in the cavernous segment of the left internal carotid artery, noted during an examination of her diplopia. Endovascular treatment was conducted by positioning a single PED (4.75 * 25 mm) across the neck of the aneurysm. The postoperative course was uneventful, and the patient was discharged 8 days post procedure. On post procedure day 10, her left oculomotor nerve palsy had worsened and she had developed left abducens nerve palsy, left exophthalmos, and left chemosis. Angiography demonstrated left direct CCF because of rupture of the aneurysm that had been treated with PED. Transvenous coil embolization was performed on post procedure day 11 to treat the CCF, and complete resolution of the CCF and significant thrombus formation within the aneurysm sac were confirmed 11 days after the second procedure. Our angiographic results suggest that the aneurysmal rupture was caused by aneurysmal volume expansion associated with PED-induced thrombosis. Transvenous coil embolization for the treatment of CCF following PED placement constitutes a new challenge.

AB - The rigidity of bacterial cell walls synthesized by a complicated pathway limit the cell shapes as coccus, bar or ellipse or even fibers. A less rigid bacterium could be beneficial for intracellular accumulation of poly-3-hydroxybutyrate (PHB) as granular inclusion bodies. To understand how cell rigidity affects PHB accumulation, E. coli cell wall synthesis pathway was reinforced and weakened, respectively. Cell rigidity was achieved by thickening the cell walls via insertion of a constitutive gltA (encoding citrate synthase) promoter in front of a series of cell wall synthesis genes on the chromosome of several E. coli derivatives, resulting in 1.32-1.60 folds increase of Young's modulus in mechanical strength for longer E. coli cells over-expressing fission ring FtsZ protein inhibiting gene sulA. Cell rigidity was weakened by down regulating expressions of ten genes in the cell wall synthesis pathway using CRISPRi, leading to elastic cells with more spaces for PHB accumulation. The regulation on cell wall synthesis changes the cell rigidity: E. coli with thickened cell walls accumulated only 25% PHB while cell wall weakened E. coli produced 93% PHB. Manipulation on cell wall synthesis mechanism adds another possibility to morphology engineering of microorganisms. PMID- 29174525 TI - Clinical phenotypes and trajectories of disease progression in type 1 spinal muscular atrophy. AB - The advent of clinical trials has highlighted the need for natural history studies reporting disease progression in type 1 spinal muscular atrophy. The aim of this study was to assess functional changes using the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND) scale in a cohort of type 1 infants. Nutritional and respiratory longitudinal data were also recorded. Patients were classified according to the severity of the phenotype and age of onset. SMN2 copies were also assessed. Twenty patients were included, eight with early onset most severe phenotype, eight with the more typical type 1 phenotype and 4, who achieved some head control, with a milder phenotype. Both baseline values and trajectories of progression were different in the three subgroups (p = 0.0001). Infants with the most severe phenotype had the lowest scores (below 20) on their first assessment and had the most rapid decline. Those with the typical phenotype had scores generally between 20 and 40 and also had a fast decline. The infants with the milder phenotype had the highest scores, generally above 35, and a much slower deterioration. Infants with three SMN2 copies had an overall milder phenotype and milder progression while two SMN2 copies were found in all three subgroups. PMID- 29174526 TI - Timed function tests, motor function measure, and quantitative thigh muscle MRI in ambulant children with Duchenne muscular dystrophy: A cross-sectional analysis. AB - The development of new therapeutic agents for the treatment of Duchenne muscular dystrophy has put a focus on defining outcome measures most sensitive to capture treatment effects. This cross-sectional analysis investigates the relation between validated clinical assessments such as the 6-minute walk test, motor function measure and quantitative muscle MRI of thigh muscles in ambulant Duchenne muscular dystrophy patients, aged 6.5 to 10.8 years (mean 8.2, SD 1.1). Quantitative muscle MRI included the mean fat fraction using a 2-point Dixon technique, and transverse relaxation time (T2) measurements. All clinical assessments were highly significantly inter-correlated with p < 0.001. The strongest correlation with the motor function measure and its D1-subscore was shown by the 6-minute walk test. Clinical assessments showed no correlation with age. Importantly, quantitative muscle MRI values significantly correlated with all clinical assessments with the extensors showing the strongest correlation. In contrast to the clinical assessments, quantitative muscle MRI values were highly significantly correlated with age. In conclusion, the motor function measure and timed function tests measure disease severity in a highly comparable fashion and all tests correlated with quantitative muscle MRI values quantifying fatty muscle degeneration.

AB - Charcot-Marie-Tooth neuropathy (CMT) is a genetically and clinically heterogeneous group of neuromuscular disorders with an overall prevalence of 1 per 2500. Here we report the first comprehensive genetic epidemiology study of Hungarian CMT patients. 409 CMT1 and 122 CMT2 patients were enrolled and genetic testing of PMP22, GJB1, MPZ, EGR2 and MFN2 genes were performed routinely. NDRG1 and CTDP1 genes were screened only for founder mutations in Roma patients. Causative genetic mutations were identified in 67.2% of the CMT1 and in 33.6% of the CMT2 cases, which indicates an overall success rate of 59.9% in the study population. Considering all affected individuals, alterations were most frequently found in PMP22 (40.5%), followed by GJB1 (9.2%), MPZ (4.5%), MFN2 (2.5%), NDRG1 (1.5%), EGR2 (0.8%) and CTDP1 (0.8%). The phenotypic spectrum and the disease severity of the studied patients also varied broadly. Deafness and autoimmune disorders were more often associated with PMP22 duplication, while MFN2 and GJB1 mutations were frequently present with central nervous system abnormalities. Our study may be helpful in determining the strategy of genetic diagnostics in Hungarian CMT patients. PMID- 29174528 TI - Food allergy in the developing world. PMID- 29174529 TI - Adjunctive azapirone for schizophrenia: A meta-analysis of randomized, double blind, placebo-controlled trials. AB - Azapirones, which are serotonin1A (5-HT1A) receptor partial agonists, have been used as an adjunctive treatment for schizophrenia with mixed results. This is a meta-analysis of the efficacy and tolerability of azapirones for schizophrenia based on randomized, double-blind, placebo-controlled trials (RCTs). English and Chinese databases were systematically and independently searched by two investigators. Data were extracted and analyzed using the RevMan software (version 5.3). Seven RCTs (n = 368) of azapirones (buspirone in 6 RCTs and tandospirone in 1 RCT) were identified and analyzed. Only adjunctive buspirone outperformed placebo regarding total psychopathology [standardized mean difference: -1.03 (95% confidence interval (CI): -1.91, -0.15), P = 0.02; I2 = 92%], but the significance disappeared in sensitivity analysis after removing two outlying studies, and in 10 of the 12 subgroup analyses. In 5 RCTs examining neurocognitive function of azapirones, only 2 RCTs found the superiority of buspirone in improving attention/speeded motor performance, verbal and performance intelligence. Adjunctive buspirone outperformed placebo regarding extrapyramidal symptoms [SMD:-0.51, (95%CI: -0.99, -0.02), P = 0.04; I2 = 0%]. Similar rates of discontinuation [risk ratio:1.06 (95%CI:0.54, 2.07), P = 0.86, I2 = 0%] and adverse drug reactions were found between both groups. Adjunctive buspirone and tandospirone failed to show efficacy for psychotic symptoms, but adjunctive buspirone may be associated with improvement in extrapyramidal symptoms and cognitive deficits in schizophrenia. Due to the preliminary nature of this meta-analysis, larger sample size and higher quality RCTs are needed to confirm these finding. PMID- 29174531 TI - Can we increase speed and efficacy of antidepressant treatments? Part I: General aspects and monoamine-based strategies. AB - Major depressive disorder (MDD) is a severe psychiatric syndrome with high prevalence and socioeconomic impact. Current antidepressant treatments are based on the blockade of serotonin (5-hydroxytryptamine, 5-HT) and/or noradrenaline transporters. These drugs show slow onset of clinical action and limited efficacy, partly due to the activation of physiological negative feed-back mechanisms operating through autoreceptors (5-HT1A, 5-HT1B, alpha2-adrenoceptors) and postsynaptic receptors (e.g., 5-HT3). As a result, clinically-relevant doses of reuptake inhibitors increase extracellular (active) 5-HT concentrations in the midbrain raphe nuclei but not in forebrain, as indicated by rodent microdialysis studies and by PET-scan studies in primate/human brain. The prevention of these self-inhibitory mechanisms by antagonists of the above receptors augments preclinical and clinical antidepressant effects. Hence, the mixed beta adrenoceptor/5-HT1A antagonist pindolol accelerated, and in some cases enhanced, the clinical action of selective serotonin reuptake inhibitors (SSRI). This strategy has been incorporated into two new multi-target antidepressant drugs, vilazodone and vortioxetine, which combine 5-HT reuptake inhibition and partial agonism at 5-HT1A receptors. Vortioxetine shows also high affinity for other 5-HT receptors, including excitatory 5-HT3 receptors located in cortical and hippocampal GABA interneurons. 5-HT3 receptor blockade by vortioxetine enhances pyramidal neuron activity in prefrontal cortex as well as cortical and hippocampal 5-HT release. It is still too soon to know whether these new antidepressants will represent a real advance over existing drugs in the real world. However, their development opened the way to future antidepressant drugs based on the prevention of local and distal self-inhibitory mechanisms attenuating monoamine activity. PMID- 29174532 TI - Acute kidney injury and 1-year mortality after left ventricular assist device implantation. AB - BACKGROUND: Data on the consequences of acute kidney injury (AKI) after continuous-flow left ventricle assist device (LVAD) implantation are scarce and inconsistent. In this study, we evaluated the incidence, predictors and the impact of AKI on mortality and renal function in the first year after LVAD implantation. METHODS: A retrospective, multicenter cohort study was conducted, including all patients (age >=18 years) undergoing LVAD implantation (91% with a HeartMate II device and 9% with a HeartWare device). The definition proposed by the Kidney Disease Improving Global Outcome (KDIGO) criteria was used to define AKI. RESULTS: Overall, 241 patients (mean age 52.4 +/- 12.9 years, 76% males) were included in the study. AKI criteria were met in 169 (70%) patients, of whom 109 (45%) were in AKI Stage I, 22 (9%) in Stage II and 38 (16%) in Stage III. Two factors, the need for pre-operative inotropic support and pre-existent chronic kidney disease Stage <=II (estimated glomerular filtration rate [eGFR] <30 ml/min/1.73 m2), were independently associated with the development of AKI and the severity of AKI stages. One-year mortality rates in patients without AKI and AKI Stages I, II and III were 18.7%, 26.4%, 23%, and 51%, respectively (log rank, p = 0.001). In the multivariable analysis, AKI Stage >=II was independently associated with mortality (hazard ratio 2.2 [95% confidence interval 1.1 to 4.5], p = 0.027) and worse renal function (beta = -7.4 [95% confidence interval -12.6 to -2.1], p < 0.01) at 1 year. CONCLUSION: AKI is highly frequent after LVAD implantation. More severe AKI stages are associated with higher mortality rates and impaired renal function at 1 year after LVAD implantation. PMID- 29174530 TI - Increased cortical neuronal responses to NMDA and improved attentional set shifting performance in rats following prebiotic (B-GOS(r)) ingestion. AB - We have previously shown that prebiotics (dietary fibres that augment the growth of indigenous beneficial gut bacteria) such as BimunoTM galacto-oligosaccharides (B-GOS(r)), increased N-methyl-D-aspartate (NMDA) receptor levels in the rat brain. The current investigation examined the functional correlates of these changes in B-GOS(r)-fed rats by measuring cortical neuronal responses to NMDA using in vivo NMDA micro-iontophoresis electrophysiology, and performance in the attentional set-shifting task. Adult male rats were supplemented with B-GOS(r) in the drinking water 3 weeks prior to in vivo iontophoresis or behavioural testing. Cortical neuronal responses to NMDA iontophoresis, were greater (+30%) in B GOS(r) administered rats compared to non-supplemented controls. The intake of B GOS(r) also partially hindered the reduction of NMDA responses by the glycine site antagonist, HA-966. In the attentional set-shifting task, B-GOS(r) -fed rats shifted from an intra-dimensional to an extra-dimensional set in fewer trials than controls, thereby indicating greater cognitive flexibility. An initial exploration into the mechanisms revealed that rats ingesting B-GOS(r) had increased levels of plasma acetate, and cortical GluN2B subunits and Acetyl Co-A Carboxylase mRNA. These changes were also observed in rats fed daily for 3 weeks with glyceryl triacetate, though unlike B-GOS(r), cortical histone deacetylase (HDAC1, HDAC2) mRNAs were also increased which suggested an additional epigenetic action of direct acetate supplementation. Our data demonstrate that a pro cognitive effect of B-GOS(r) intake in rats is associated with an increase in cortical NMDA receptor function, but the role of circulating acetate derived from gut bacterial fermentation of this prebiotic requires further investigation. PMID- 29174533 TI - Impact of declining renal function on outcomes in pulmonary arterial hypertension: A REVEAL registry analysis. AB - BACKGROUND: Renal dysfunction is associated with abnormal cardiopulmonary hemodynamics, in-hospital death and poor survival in patients with pulmonary arterial hypertension (PAH), and thus it may be a prognostic biomarker. In our analysis we assess the relationship between change in estimated glomerular filtration rate (eGFR) and outcomes in PAH patients in the Registry to Evaluate Early and Long-term PAH Disease Management (REVEAL). METHODS: Overall 2,368 patients were classified into chronic kidney disease (CKD) stages based on baseline eGFR: normal or Stages 1 or 2 (n = 1,699); Stage 3a (n = 399); Stage 3b (n = 196); and Stages 4 or 5 (n = 74). We evaluated the relationship between baseline CKD stage and survival, as well as the composite end-point of survival and freedom from all-cause hospitalization. The relationships between change in eGFR at >=1 year and these clinical end-points were also evaluated. RESULTS: Patients with a >=10% decline in eGFR from baseline over >=1 year had a significantly increased risk of death (hazard ratio 1.66; p < 0.0001) and the composite of all-cause hospitalization and death (hazard ratio 1.33; p = 0.002). This decline predicted survival independently of changes in 6-minute walk distance and functional class. However, a >=10% increase in eGFR was not significantly associated with either end-point. CONCLUSION: In REVEAL, a >=10% decline in eGFR over >=1 year independently predicted poorer survival. Thus, eGFR may be a simple and economical biomarker in PAH. PMID- 29174534 TI - Subject-specific toe-in or toe-out gait modifications reduce the larger knee adduction moment peak more than a non-personalized approach. AB - The knee adduction moment (KAM) is a surrogate measure for medial compartment knee loading and is related to the progression of knee osteoarthritis. Toe-in and toe-out gait modifications typically reduce the first and second KAM peaks, respectively. We investigated whether assigning a subject-specific foot progression angle (FPA) modification reduces the peak KAM by more than assigning the same modification to everyone. To explore the effects of motor learning on muscle coordination and kinetics, we also evaluated the peak knee flexion moment and quadriceps-hamstring co-contraction during normal walking, when subjects first learned their subject-specific FPA, and following 20 min of training. Using vibrotactile feedback, we trained 20 healthy adults to toe-in and toe-out by 5 degrees and 10 degrees relative to their natural FPA, then identified the subject-specific FPA as the angle where each subject maximally reduced their larger KAM peak. When walking at their subject-specific FPA, 18 subjects significantly reduced their larger KAM peak; 8 by toeing-in and 10 by toeing-out. On average, subjects reduced their larger KAM peak by 18.6 +/- 16.2% when walking at their subject-specific FPA, which was more than the reductions achieved when all subjects toed-in by 10 degrees (10.0 +/- 17.1%, p = .013) or toed-out by 10 degrees (11.0 +/- 18.3%, p = .002). Quadriceps-hamstring co-contraction and the peak knee flexion moment increased when subjects first learned their subject specific FPA, but only co-contraction returned to baseline levels following training. These findings demonstrate that subject-specific gait modifications reduce the peak KAM more than uniformly assigned modifications and have the potential to slow the progression of medial compartment knee osteoarthritis. PMID- 29174535 TI - Prediction of inter-individual variability on the pharmacokinetics of CYP2C8 substrates in human. AB - Inter-individual variability in pharmacokinetics can lead to unexpected side effects and treatment failure, and is therefore an important factor in drug development. CYP2C8 is a major drug-metabolizing enzyme known to be involved in the metabolism of over 100 drugs. In this study, we predicted the inter individual variability in AUC/Dose of CYP2C8 substrates in healthy volunteers using the Monte Carlo simulation. Inter-individual variability in the hepatic intrinsic clearance of CYP2C8 substrates (CLint,h,2C8) was estimated from the inter-individual variability in pharmacokinetics of pioglitazone, which is a major CYP2C8 substrate. The coefficient of variation (CV) of CLint,h,2C8 was estimated to be 40%. Using this value, the CVs of AUC/Dose of other major CYP2C8 substrates, rosiglitazone and amodiaquine, were predicted to validate the estimated CV of CLint,h,2C8. As a result, the reported CVs of both substrates were within the 2.5-97.5 percentile range of the predicted CVs. Furthermore, the CVs of AUC/Dose of the CYP2C8 substrates loperamide and chloroquine, which are affected by renal clearance, were also successfully predicted. Combining this value with previously reported CVs of other CYPs, we were able to successfully predict the inter-individual variability in pharmacokinetics of various drugs in clinical. PMID- 29174536 TI - Monophosphorylation by deoxycytidine kinase affects apparent cellular uptake of decitabine in HCT116 colon cancer cells. AB - Decitabine (DAC), a nucleoside-related DNA methylation inhibitor, is taken up into cancer cells via equilibrative nucleoside transporter 1 (ENT1), and is then monophosphorylated by deoxycytidine kinase (dCK). In the present study, we examined the contribution of dCK to the uptake of DAC in HCT116 colon cancer cells. Irinotecan and etoposide inhibited the uptake of [3H]-uridine and [3H]-DAC at 10 s and 5 min, while cytarabine and gemcitabine only inhibited that of [3H] DAC at 5 min. Irinotecan and etoposide inhibited [3H]-DAC uptake in negative control small interfering RNA (siRNA)- or dCK siRNA-transfected cells at 10 s, whereas cytarabine and gemcitabine did not. Cytarabine and gemcitabine inhibited DAC monophosphate generation by the cytosolic proteins of HCT116 cells and recombinant human dCK protein, assessed using polyethylenimine cellulose thin layered chromatography. Simulations using simple kinetic models showed that apparent DAC uptake in dCK and ENT1 siRNA-treated cells was attributed to its conversion to monophosphates or a decrease in the cellular flux, respectively, and that the apparent uptake of DAC in dCK-knockdown and ENT1-knockdown cells was similar at longer times, but differed at a very short time. These results suggest that the apparent uptake of DAC is affected by ENT1 and dCK in HCT116 cells. PMID- 29174537 TI - Flow cytometry-based method for rapid and high-throughput screening of hybridoma cells secreting monoclonal antibody. AB - Monoclonal antibodies (mAbs) are a valuable biomaterial for basic life sciences and industrial purposes. The production of the mAb is time and effort intensive. In this report, we established a time- and labor-saving method for the mAb production. Because membrane-type immunoglobulin on a hybridoma cell surface and its secreted form, called as antibody, share the same binding property to the antigen, the fluorescence-labeled antigen bound to membrane-type immunoglobulin can be used as a screening marker. In the method, a hybridoma labeled by a fluorescent antigen was selected and sorted singly into 96-well plate using flow cytometer. Model experiments indicated that the method is highly efficient to obtain good mAbs suitable for Western blotting and immunofluorescence. Notably, most mAbs established by this method belonged to the IgG isotype, which is preferred over the IgM counterpart. Using a high-throughput flow cytometer, the method avoids tedious repeated screening and cloning processes. Because the method uses conventional myeloma for cell fusion and all reagents required in this method are commercially available, all research laboratories can apply the method to obtain mAbs efficiently.

PMID- 29174538 TI - Attendance at Mental Health Appointments by Women Who Were Referred During Pregnancy or the Postpartum Period. AB - OBJECTIVE: To describe characteristics of women referred to mental health care during pregnancy or the year after giving birth and to identify characteristics associated with attendance at mental health intake visits. DESIGN: Retrospective record review of referral documentation. SETTING: Women's health practices and perinatal mental health clinics in urban areas. PARTICIPANTS: The sample included 647 women during pregnancy or the year after giving birth who were referred for mental health treatment. METHODS: We reviewed the referral data sent from women's health care providers to perinatal mental health clinics to determine if mental health visits occurred. RESULTS: Fifty percent of the 647 women who accepted perinatal mental health referrals had intake appointments. Women were more likely to participate in an intake appointment if in-home services were offered (p < .01). Those with lower income were also more likely to participate (p < 0.05). Those with histories of perinatal loss and those who self-referred tended to be more likely to participate, although these relationships were statistically nonsignificant. CONCLUSION: Even among women who accepted referrals to mental health services, only half attended intake appointments. For this group of pregnant women and those in the first year after birth, in-home mental health visits were most likely to result in care engagement, which has important implications for service delivery. PMID- 29174540 TI - Small-Molecule Kinase Downregulators. AB - New opportunities to advance small-molecule kinase ligands that downregulate their cognate target binding proteins are discussed. Rationally designed heterobifunctional kinase degraders are compared with ATP site ligands that were serendipitously found to cause kinase downregulation. These approaches could be particularly useful in the treatment of cancers since many kinases are known to remodel pro-oncogenic protein-protein interactions, which could be destroyed by small-molecule-mediated kinase depletion. PMID- 29174541 TI - Engineered Multivalent Sensors to Detect Coexisting Histone Modifications in Living Stem Cells. AB - The regulation of fundamental processes such as gene expression or cell differentiation involves chromatin states, demarcated by combinatorial histone post-translational modification (PTM) patterns. The subnuclear organization and dynamics of chromatin states is not well understood, as tools for their detection and modulation in live cells are lacking. Here, we report the development of genetically encoded chromatin-sensing multivalent probes, cMAPs, selective for bivalent chromatin, a PTM pattern associated with pluripotency in embryonic stem cells (ESCs). cMAPs were engineered from a set of PTM-binding (reader) proteins and optimized using synthetic nucleosomes carrying defined PTMs. Applied in live ESCs, cMAPs formed discrete subnuclear foci, revealing the organization of bivalent chromatin into local clusters. Moreover, cMAPs enabled direct monitoring of the loss of bivalency upon treatment with small-molecule epigenetic modulators. cMAPs thus provide a versatile platform to monitor chromatin state dynamics in live cells.

PMID- 29174542 TI - Quantitative, Wide-Spectrum Kinase Profiling in Live Cells for Assessing the Effect of Cellular ATP on Target Engagement. AB - For kinase inhibitors, intracellular target selectivity is fundamental to pharmacological mechanism. Although a number of acellular techniques have been developed to measure kinase binding or enzymatic inhibition, such approaches can fail to accurately predict engagement in cells. Here we report the application of an energy transfer technique that enabled the first broad-spectrum, equilibrium based approach to quantitatively profile target occupancy and compound affinity in live cells. Using this method, we performed a selectivity profiling for clinically relevant kinase inhibitors against 178 full-length kinases, and a mechanistic interrogation of the potency offsets observed between cellular and biochemical analysis. For the multikinase inhibitor crizotinib, our approach accurately predicted cellular potency and revealed improved target selectivity compared with biochemical measurements. Due to cellular ATP, a number of putative crizotinib targets are unexpectedly disengaged in live cells at a clinically relevant drug dose.

PMID- 29174546 TI - Efficacy of Ledipasvir and Sofosbuvir Treatment of HCV Infection in Patients Coinfected With HBV. AB - BACKGROUND & AIMS: There have been reports of reactivation of hepatitis B virus (HBV) infection during treatment of hepatitis C virus (HCV) infection with direct acting antiviral agents. We performed a prospective study of risks and outcomes of HCV infection treatment with ledipasvir and sofosbuvir in patients with HBV infection. METHODS: We performed a phase 3b, multicenter, open-label study in Taiwan of 111 patients with HCV infection (61% HCV genotype 1, 39% HCV genotype 2 infection; 62% women, 16% with compensated cirrhosis) along with HBV infection. All but 1 were positive for the hepatitis B surface antigen (HBsAg); 1 patient who was HBsAg-positive at screening was found to be HBsAg-negative at baseline. Overall, 33% of participants had received prior treatment for HCV and 5% had previously been treated for HBV; no patient was on HBV therapy at the start of the study. All patients received a fixed-dose combination of 90 mg of the HCV NS5A inhibitor ledipasvir with 400 mg of the NS5B nucleotide analogue inhibitor sofosbuvir, once daily for 12 weeks. The primary endpoint was sustained virologic response 12 weeks after the end of therapy. RESULTS: All 111 patients (100%) achieved a sustained virologic response. Of the 37 patients with baseline HBV DNA below 20 IU/mL, 31 (84%) had at least 1 episode of quantifiable HBV DNA through posttreatment week 12. Of the 74 patients with baseline HBV DNA levels of 20 IU/mL or more, 39 (53%) had increases of HBV DNA greater than 1 log10 IU/mL through posttreatment week 12. Overall, 5 patients had increased levels of HBV DNA concomitant with a level of alanine aminotransferase >2 times the upper limit of normal through posttreatment week 12. Of these, 3 patients started HBV treatment. In addition, 1 patient with HBV reactivation since week 8 and concomitant alanine aminotransferase elevation >2 times upper limit of normal at posttreatment week 48 started treatment at posttreatment week 53. This patient had clinical signs and symptoms associated with HBV reactivation. The most common adverse events were headache, upper respiratory infection, and fatigue. CONCLUSIONS: In a prospective study, the combination of ledipasvir and sofosbuvir for 12 weeks produced a sustained virologic response in 100% of patients with HCV infection who were coinfected with HBV. Most patients had an increase in level of HBV DNA not associated with signs or symptoms. ClinicalTrials.gov no: NCT02613871.

PMID- 29174549 TI - Identification and characterization of potential druggable targets among hypothetical proteins of extensively drug resistant Mycobacterium tuberculosis (XDR KZN 605) through subtractive genomics approach. AB - Among the resistant isolates of tuberculosis (TB), the multidrug resistance tuberculosis (MDR-TB) and extensively drug resistant tuberculosis (XDR-TB) are the areas of growing concern for which the front-line antibiotics are no more effective. As a result, the search of new therapeutic targets against TB is an imperative need of time. On the other hand, the target identification is an a priori step in drug discovery based research. Furthermore, the availability of the complete proteomic data of extensively drug resistant Mycobacterium tuberculosis (XDR-MTB) made it possible to carry out in silico analysis for the discovery of new drug targets. In the current study, we aimed to prioritize the potential drug targets among the hypothetical proteins of XDR-TB via subtractive genomics approach. In the subtractive genomics, we stepwise reduced the complete proteome of XDR-MTB to only two hypothetical proteins and evidently proposed them as new therapeutic targets. The 3D structure of one of the two target proteins was predicted via homology modeling and later on, validated by various analysis tools. Our study suggested that the domains identified and the motif hits found in the sequences of the shortlisted drug targets are crucial for the survival of the XDR-MTB. To the best of our knowledge, the current study is the first attempt in which the complete proteomic data of XDR-MTB was subjected to the computational subtractive genomics approach and therefore, would provide an opportunity to identify the unique therapeutic targets against deadly XDR-MTB. PMID- 29174550 TI - Three-dimensional changes of scleral show after surgical treatment of endocrine orbitopathy. AB - PURPOSE: Surgery in endocrine orbitopathy should address exophthalmos and adjunct stigmata such as increased lid aperture and scleral show. Secondary to decompression, rehabilitative surgical treatment such as blepharoplasty is routinely used to achieve this goal. Until now, however, there has been no investigation to measure the effect of decompression surgery on scleral show and lid aperture 3-dimensionally. MATERIALS AND METHODS: Ocular surface area (OSA) and lid aperture of 34 patients (67 orbits) were measured pre and post decompression surgery in a retrospective investigation using 3-dimensional (3D) stereophotogrammetry. The mean follow-up after decompression was 6 +/- 4 months. RESULTS: Mean OSA ranged between 3.1 +/- 1.5 cm2 (pre orbital decompression) and 2.5 +/- 0.6 cm2 (post orbital decompression). Orbital decompression caused a statistically significant reduction of the surface area of about 19.4% (p < 0.001). Lid apertures showed average values between 12.7 +/- 3.3 mm (pre orbital decompression) and 11.3 +/- 2.2 mm (post orbital decompression). Thus orbital decompression led to a statistically significant reduction of the palpebral fissure of about 11% (p < 0.001). OSA correlated with lid aperture pre and post surgery (p < 0.001). The extent of OSA reduction showed no correlation with the amount of exophthalmos reduction. CONCLUSION: Our results show that surgical decompression, besides correcting exophthalmos, leads to a significant reduction of scleral show and lid aperture. However, it is not possible to estimate its effect on an individual basis. PMID- 29174551 TI - Surgical management of severe osteoradionecrosis of the mandibular bone by using double free flap reconstruction. AB - PURPOSE: Osteoradionecrosis (ORN) of the jaws represents one of the most severe complications after primary or adjuvant radiation therapy (RT) of large head and neck tumors. In advanced ORN cases, surgical management is generally considered the therapy of choice. However, in several severe ORN patients with extensive bone and soft tissue defects, functional and aesthetic reconstruction represents a huge challenge for any surgeon, with an increased risk of post-operative wound healing disorders. Our aim here was to perform a double free flap technique as a therapeutic option in this difficult patient collective and to evaluate the post operative outcome. MATERIALS AND METHODS: 15 patients with advanced and severe ORN undergoing mandibular and soft tissue reconstruction with a double free flap were retrospectively reviewed. In one single operation involving a three-team approach, an obligatory free fibular flap (FFF) was freely combined with another free flap according to the desired features: anterolateral thigh (ALT) or vastus lateralis flap (VLF), radial forearm flap (RFF) and latissimus dorsi flap (LDF). RESULTS: We found sufficient wound healing in the head and neck region in all patients with no need for any additional surgical intervention. The overall flap success rate was 93.3%, although three revisions of anastomosis were necessary. Furthermore, prolonged stay on the intensive care unit (ICU) and extended hospitalisation were avoided. CONCLUSION: The double free flap technique with an obligatory FFF provides a suitable surgical solution for the treatment of patients with severe ORN of the mandibular bone for which other conservative or surgical therapy strategies have reached their limits. PMID- 29174552 TI - Simultaneous reconstruction of columella and philtrum using prolabial flap combined with Abbe flap in secondary bilateral cleft lip and nasal deformity. AB - Open rhinoplasty and Abbe flap techniques are traditionally useful tools for the reconstruction of secondary bilateral cleft lip nasal (BCLN) deformity. We aimed to investigate the long-term outcomes of simultaneous columella and philtrum reconstruction using prolabial flap combined with Abbe flap in secondary BCLN deformity. From January 2009 to July 2014, 26 patients (17 males and 9 females; mean age 21 years) with secondary BCLN deformity were recruited. All patients had severe short columella and philtrum deficiency. The whole superiorly based prolabial flap was harvested and trimmed for columella reconstruction. An Abbe flap from the central lower lip was elevated to reconstruct the esthetic philtral unit. No flap necrosis occurred postoperatively. The average follow-up was 2.7 years. The columella length was 4.7 +/- 1.3 mm preoperatively and 10.4 +/- 2.1 mm postoperatively. The philtrum length increased to 14.4 +/- 2.6 mm postoperatively from a preoperative 8.9 +/- 2.4 mm. Regarding the overall impression of the reconstruction, 22 patients ranked it as very good or good. In secondary BCLN deformity, the prolabial flap combined with Abbe flap technique is an effective alternative for the treatment of severe short columella complicated with severe philtrum deficiency. PMID- 29174553 TI - Primary aesthetic correction of nasal anomaly with costal graft in treating orbital hypertelorism. AB - : Orbital hypertelorism is a common congenital craniofacial anomaly in Asians. As Tessier pointed out, the correction of hypertelorism is effectively the correction of the nasal deformity, which is characterized by a broad, flat nose accompanying an increased interorbital distance and a lack of nasal projection. OBJECTIVES: To measure the changes in the orbital and nasal parameters after Tessier box osteotomy and primary aesthetic rhinoplasty, performed concurrently with otogenous costochondral graft. METHODS: From 2009 to 2013, 49 hypertelorism patients were treated in our craniofacial unit. Correction involved a classic Tessier box osteotomy combined with aesthetic augmentation and reconstruction of the nasal dorsum using a costochondral graft. All patients underwent photographic and tomographic documentation both before and 12 months after surgery. Patients underwent morphometric analysis to document the change in interorbital distance, IOD, hypertelorism index, and aesthetic nasal parameters, including the nasal dorsum and alar width, the nasal dorsal height, and the index of nasal apex protrusion versus nasal length. RESULTS: All patients were satisfied with the outcome of the combined orbital and nasal repair. Morphometric analysis indicated that the IOD, hypertelorism index, and aesthetic nasal parameters all improved following surgery. The resorption rate of the costochondral graft was 16-19%, and graft warpage was nearly absent. Although complications included infection, cerebrospinal fluid leak, and hyposomia, no severe or life-threatening complications occurred. CONCLUSION: Tessier box osteotomy with primary aesthetic rhinoplasty using costochondral grafts has shown to be efficacious in the treatment of patients with hypertelorism. PMID- 29174554 TI - Novel computer vision analysis of nasal shape in children with unilateral cleft lip. AB - BACKGROUND: Optimization of treatment of the unilateral cleft lip nasal deformity (uCLND) is hampered by lack of objective means to assess initial severity and changes produced by treatment and growth. The purpose of this study was to develop automated 3D image analysis specific to the uCLND; assess the correlation of these measures to esthetic appraisal; measure changes that occur with treatment and differences amongst cleft types. METHODS: Dorsum Deviation, Tip Alar Volume Ratio, Alar-Cheek Definition, and Columellar Angle were assessed using computer-vision techniques. Subjects included infants before and after primary cleft lip repair (N = 50) and children aged 8-10 years with previous cleft lip (N = 50). Two expert surgeons ranked subjects according to esthetic nose appearance. RESULTS: Computer-based measurements strongly correlated with rankings of infants pre-repair (r = 0.8, 0.75, 0.41 and 0.54 for Dorsum Deviation, Tip-Alar Volume Ratio, Alar-Cheek Definition, and Columellar Angle, p < 0.01) while all measurements except Alar-Cheek Definition correlated moderately with rankings of older children post-repair (r ~ 0.35, p < 0.01). Measurements were worse with greater severity of cleft type but improved following initial repair. Abnormal Dorsum Deviation and Columellar Angle persisted after surgery and were more severe with greater cleft type. CONCLUSIONS: Four fully-automated measures were developed that are clinically relevant, agree with expert evaluations and can be followed through initial surgery and in older children. Computer vision analysis techniques can quantify the nasal deformity at different stages, offering efficient and standardized tools for large studies and data driven conclusions. PMID- 29174556 TI - Risk of borderline ovarian tumors among women with benign ovarian tumors: A cohort study. AB - OBJECTIVE: A growing number of studies suggest that some ovarian cancers can arise from benign and borderline ovarian tumors. However, studies on the association between benign and borderline ovarian tumors are lacking. We studied the overall- and histotype-specific risk of borderline ovarian tumors among women with a benign ovarian tumor. METHODS: This nationwide cohort study included all Danish women diagnosed with a benign ovarian tumor (n=139,466) during 1978-2012. The cohort was linked to the Danish Pathology Data Bank and standardized incidence ratios (SIR) with 95% confidence intervals (CI) were calculated. RESULTS: Women with benign ovarian tumors had increased risks for subsequent borderline ovarian tumors (SIR 1.62, 95% CI 1.43-1.82), and this applied to both serous (SIR 1.69, 95% CI 1.39-2.03) and mucinous (SIR 1.75, 95% CI 1.45-2.10) histotypes of borderline ovarian tumors. The risk for borderline ovarian tumors was primarily increased for women diagnosed with a benign ovarian tumor before 40years of age. The risk remained increased up to 9years after a benign ovarian tumor diagnosis. Finally, the associations did not change markedly when analyzed for the different histotypes of benign (solid and cystic tumors) and borderline (serous and mucinous tumors) ovarian tumors. CONCLUSIONS: Women with benign ovarian tumors have a long-term increased risk for borderline ovarian tumors. However, as all associations in this study were only adjusted for age and calendar period of diagnosis, more studies that are able to adjust for additional potential confounding variables are required to further understand these associations. PMID- 29174557 TI - Not all is noticed: Kinematic cues of emotion-specific gait. AB - Perceiving emotions from gait can serve numerous socio-environmental functions (e.g. perceiving threat, sexual courting behaviours). Participant perceivers were asked to report their strategies for identifying happiness, sadness, anger and fear in point-light walkers. Perceivers claimed they identified happiness by a bouncing gait with increased arm movement, sadness by a slow slouching gait, anger by a fast stomping gait and fear by both fast and slow gaits. The emotion specific point-light walker stimuli were kinematically analysed to verify the presence of the gait cues perceivers reported using to identify each emotion. Happy and angry walkers both displayed long strides with increased arm movement though angry strides had a faster cadence. Fearful walkers walked with fast short strides reminiscent of a scurrying gait. Sad walkers walked with slow short strides consequently creating the slowest walking pace. However, fearful and sad walkers showed less arm movement in their gait in different ways. Sad walkers moved their entire arms whilst fearful walkers primarily moved their lower arms throughout their gait. PMID- 29174555 TI - Predictive modeling for determination of microscopic residual disease at primary cytoreduction: An NRG Oncology/Gynecologic Oncology Group 182 Study. AB - OBJECTIVE: Microscopic residual disease following complete cytoreduction (R0) is associated with a significant survival benefit for patients with advanced epithelial ovarian cancer (EOC). Our objective was to develop a prediction model for R0 to support surgeons in their clinical care decisions. METHODS: Demographic, pathologic, surgical, and CA125 data were collected from GOG 182 records. Patients enrolled prior to September 1, 2003 were used for the training model while those enrolled after constituted the validation data set. Univariate analysis was performed to identify significant predictors of R0 and these variables were subsequently analyzed using multivariable regression. The regression model was reduced using backward selection and predictive accuracy was quantified using area under the receiver operating characteristic area under the curve (AUC) in both the training and the validation data sets. RESULTS: Of the 3882 patients enrolled in GOG 182, 1480 had complete clinical data available for the analysis. The training data set consisted of 1007 patients (234 with R0) while the validation set was comprised of 473 patients (122 with R0). The reduced multivariable regression model demonstrated several variables predictive of R0 at cytoreduction: Disease Score (DS) (p<0.001), stage (p=0.009), CA125 (p<0.001), ascites (p<0.001), and stage-age interaction (p=0.01). Applying the prediction model to the validation data resulted in an AUC of 0.73 (0.67 to 0.78, 95% CI). Inclusion of DS enhanced the model performance to an AUC of 0.83 (0.79 to 0.88, 95% CI). CONCLUSIONS: We developed and validated a prediction model for R0 that offers improved performance over previously reported models for prediction of residual disease. The performance of the prediction model suggests additional factors (i.e. imaging, molecular profiling, etc.) should be explored in the future for a more clinically actionable tool. PMID- 29174558 TI - Anesthesia and sleep apnea. AB - Due to its low rate of diagnosis, in the general population over half of those experiencing obstructive sleep apnea (OSA) are unaware that they have the condition. However, any acute medical event may exacerbate OSA and could have serious health consequences. In this context the management of the perioperative period, from anesthesia through the surgery itself and into the postoperative period, is more problematic for patients with sleep disordered breathing than for others. There is prolific literature in this area although large randomized trials are few due to the high sample size needed and possible ethical difficulties of withholding OSA treatment in the perioperative period. In 2014 the American Society of Anesthesiologists published an updated set of recommendations to guide OSA management during the perioperative period. In this present review we provide an overview of the different issues that practitioners face with regard to OSA, from the initial consultation with the anesthesiologist to the extended post-operative period. There is considerable evidence that OSA patients are at high risk of perioperative complications, though the inherent risks from OSA per se and its comorbidities remain difficult to discern. Nevertheless, appropriate screening and management allow clinicians to minimize OSA associated risk. PMID- 29174559 TI - Assessment of the severity of native mitral valve regurgitation. AB - Mitral regurgitation (MR) is a major cause of cardiovascular morbidity and mortality. MR is classified as primary (organic) if it is due to an intrinsic valve abnormality, or secondary (functional) if the etiology is because of remodeling of left ventricular geometry and/or valve annulus. Transthoracic echocardiography (TTE) is the initial modality for MR evaluation. Parameters used for the assessment of MR include valve structure, cardiac remodeling, and color and spectral Doppler. Quantitative measurements include effective regurgitant orifice area, regurgitant volume, and regurgitant fraction. Knowledge of advantages and limitations of echo-Doppler parameters is essential for accurate results. An integrative approach is recommended in overall grading of MR as mild, moderate, or severe since singular parameters may be affected by several factors. When the mechanism and/or grade of MR is unclear from the TTE or is discrepant with the clinical scenario, further evaluation with transesophageal echocardiography or cardiac magnetic resonance imaging is recommended, the latter emerging as a powerful MR quantitation tool.

PMID- 29174560 TI - Resident Vignettes for Assessing Care Quality in Nursing Homes. AB - OBJECTIVES: Validated process measures that correlate with patient outcomes are needed for research and quality improvement. DESIGN: Cross-sectional analysis within a cluster-randomized fall prevention study. SETTING: Nursing homes in North Carolina (n = 16). PARTICIPANTS: Nursing home staff (n = 541) and residents with 1 or more falls in 6 months (n = 597). MEASUREMENTS: Fall-prevention process measures in 4 categories derived from Assessing Care of Vulnerable Elders quality indicators were measured in 2 ways: (1) chart abstraction; and (2) staff responses to clinical vignettes of hypothetical residents at risk for falls. Recurrent fall rates (falls/resident/year) were measured. The proportion of the total variation in falls rates explained by the scores for each method (chart abstraction or vignette) was calculated using multilevel adjusted models. RESULTS: Chart and vignette measures of comorbidity management were moderately correlated (Pearson correlation coefficient 0.43), whereas other process measure categories had low or negative correlation between the 2 methods (psychoactive medication reduction 0.13, environmental modification -0.42, and exercise/rehabilitation -0.08). Measures of environmental modification and comorbidity management explained a moderate amount of the total variation in recurrent fall fates, vignettes (7%-10% variation explained) were superior to chart abstraction (2%-6% variation explained). Vignette responses from unlicensed staff (nurse aides and rehabilitation aides) explained more variance than registered nurses, licensed practical nurses, or other licensed staff in these categories. Process measures for psychoactive medication reduction and exercise/rehabilitation did not explain any of the variation in fall outcomes. Overall, vignette process measures explained 3.9% and chart abstraction measures explained 0% of the variation in fall outcomes. CONCLUSIONS: Clinical vignettes completed by nursing home staff had greater association with resident recurrent fall rates than traditional chart abstraction process measures. PMID- 29174562 TI - An Even Distribution of Protein Intake Daily Promotes Protein Adequacy but Does Not Influence Nutritional Status in Institutionalized Elderly. AB - OBJECTIVE: Although it has been established that sufficient protein is required to maintain good nutritional status and support healthy aging, it is not clear if the pattern of protein consumption may also influence nutritional status, especially in institutionalized elderly who are at risk of malnutrition. Therefore, we aim to determine the association between protein intake distribution and nutritional status in institutionalized elderly people. DESIGN: Cross-sectional study among 481 institutionalized older adults. METHODS: Dietary data from 481 ambulant elderly people (68.8% female, mean age 87.5 +/- 6.3 years) residing in 52 aged-care facilities in Victoria, Australia, were assessed over 2 days using plate waste analysis. Nutritional status was determined using the Mini Nutritional Assessment tool and serum (n = 208) analyzed for albumin, hemoglobin, and IGF-1. Protein intake distribution was classified as: spread (even distribution across 3 meals, n = 65), pulse (most protein consumed in one meal, n = 72) or intermediate (n = 344). Regression analysis was used to investigate associations. RESULTS: Mean protein intakes were higher in the spread (60.5 +/- 2.0 g/d) than intermediate group (56.0 +/- 0.8 g/d, P = .037), and tended to be higher than those in the pulse group (55.9 +/- 1.9 g/d, P = .097). Residents with an even distribution of protein intake achieved a higher level of the recommended daily intake for protein (96.2 +/- 30.0%) than the intermediate (86.3 +/- 26.2%, P = .008) and pulse (87.4 +/- 30.5%, P = .06) groups, and also achieved a greater level of their estimated energy requirements (intermediate; P = .039, pulse; P = .001). Nutritional status (Mini-Nutritional Assessment score) did not differ between groups (pulse; 20.5 +/- 4.5, intermediate; 21.0 +/- 2.5, spread; 20.5 +/- 3.5), nor did any other indices of nutritional status. CONCLUSIONS: Meeting protein requirements is required before protein distribution may influence nutritional status in institutionalized elderly. Achieving adequate protein and energy intakes is more likely when protein is distributed evenly throughout the day. Provision of high protein foods especially at breakfast, and in the evening, may support protein adequacy and healthy aging, especially for institutionalized elderly.

AB - Fungi-derived defensins are a class of antimicrobial peptides with therapeutic potential due to their high antibacterial efficacy and low toxicity. Based on the genomic strategy, we have identified 68 fungal defensin-like peptides (fDLPs) in five new genera, including Trichosporon, Apophysomyces, Lichtheimia, Beauveria and Scedosporium and characterized a new synthetic defensin (scedosporisin) from an invasive fungus. It was active against Gram-positive bacteria but not active against negative bacteria. Importantly, it killed several clinical resistant isolates such as methicillin-resistant Staphylococcus aureus and vancomycin resistant Enterococci at low molecular concentrations. Scedosporisin showed low hemolysis and cytotoxicity and high serum stability. The killing kinetics of scedosporisin-2 against a clinical isolate of MRSA showed that it killed the bacteria more rapidly than that of vancomycin. Homology modeling analysis show that scedosporisin adopted a typical cysteine stabilized alpha-helical and beta sheet fold with a local hydrophobic patch. Scedosporisin significantly improved the survival rate of mice in the peritonitis model. This work has greatly expanded the library of fDLPs, and successfully selected leading molecules for antimicrobial drug reserves. PMID- 29174564 TI - Crispr-Cas9 engineered osteogenesis imperfecta type V leads to severe skeletal deformities and perinatal lethality in mice. AB - Osteogenesis imperfecta (OI) type V is caused by an autosomal dominant mutation in the IFITM5 gene, also known as BRIL. The c.-14C>T mutation in the 5'UTR of BRIL creates a novel translational start site adding 5 residues (MALEP) in frame with the natural coding of BRIL. A neomorphic function has been proposed for the MALEP-BRIL but the mechanisms at play are still unknown. In order to further understand the effects of MALEP-BRIL in vivo, we generated a knockin (KI) mouse model having the exact genetic -14C>T replica of patients with OI type V. Live KI descendants were never obtained from 2 male mosaic founders. Skeletal staining with alizarin red/alcian blue and MUCT imaging of KI embryos revealed striking skeletal anomalies such as hypomineralized skull, short and bent long bones, and frail and wavy ribs. Histology and histochemical labeling revealed that midshaft of long bones was filled with hypertrophic chondrocytes, lacked a defined primary ossification center with the absence of defined cortices. Gene expression monitoring at E15.5 and E17.5 showed no change in Osx but decreased Bril itself as well as other differentiated osteoblast markers (Ibsp, Bglap, Sost). However, upregulation of Ptgs2 and Nr4a3 suggested that a pro-inflammatory reaction was activated. Primary osteoblasts from KI calvaria showed delayed differentiation and mineralization, with decreased abundance of BRIL. However, the upregulation AdipoQ and Fabp4 in young cultures indicated a possible switch in fate towards adipogenesis. Altogether our data suggest that the low level expression of MALEP BRIL in Osx+ mesenchymal progenitors blunted their further differentiation into mature osteoblasts, which may have resulted in part from an inflammatory response. PMID- 29174565 TI - The use of patient-reported outcome tools in Gynecologic Oncology research, clinical practice, and value-based care. AB - Patient-reported outcomes (PRO) are defined as a report of a patient's symptoms, function and general well-being that comes directly from the patient, without interpretation of the response by a medical provider. As greater emphasis is placed on high-quality, patient-centered care, the importance of PROs has become widely accepted by policymakers, third party payers, medical societies, health care systems and clinical researchers. Despite increased recognition of the importance of PROs, they have not become a widely-implemented part of clinical care and their use in clinical research has been limited by methodological concerns. Health service researchers and providers are working to standardize and develop new methods to improve implementation of PROs in clinical and research settings. This article reviews the development of PRO measurement tools, implementation in the healthcare setting and relevance in clinical trials, with a focus on clinical care and research in gynecologic oncology. PMID- 29174567 TI - The unrecognized burden of cardiovascular risk factors in women newly diagnosed with endometrial cancer: A prospective case control study. AB - BACKGROUND: Cardiovascular disease is a major cause of death in endometrial cancer survivors. The aim of this study was to determine whether women newly diagnosed with endometrial cancer have a higher prevalence of cardiovascular risk factors than the general population. METHODS: The prevalence of adequately treated and unrecognized/inadequately treated cardiovascular risk factors and the corresponding 10-year cardiovascular risk by QRISK2 score was measured in 150 consecutive women undergoing primary treatment for endometrioid endometrial cancer in the North West of England, and 746 age and ethnicity-matched control women from the Health Survey for England 2014. RESULTS: Women with endometrial cancer had higher proportions of obesity (BMI>=30 60.7% vs. 32.4%, p<0.0001) and a preponderance of unrecognized and inadequately treated cardiovascular risk factors. Compared with controls, endometrial cancer cases had a higher prevalence of incident hyperglycemia (57.2%vs.11.5%, p<0.0001), total: HDL cholesterol ratio>4.5 (26.7%vs.13.7%, p<0.0001), and were more likely to have three or more cardiovascular risk factors (22%vs.6%, p<0.0001). This equates to a higher 10 year cardiovascular risk (median QRISK2 score 12.6% vs. 8.8%, p<0.0001). Optimization of risk factors would have a greater impact on absolute cardiovascular disease risk for cases than controls (QRISK2 score reduction 1.8% vs. 0.7%). CONCLUSIONS: Women undergoing primary treatment for endometrial cancer have a higher prevalence of cardiovascular risk factors than women without the disease. Early identification and treatment of these risk factors could improve outcomes for endometrial cancer survivors. PMID- 29174566 TI - The roles of pathology in targeted therapy of women with gynecologic cancers. AB - The role of the pathologist in the multidisciplinary management of women with gynecologic cancer has evolved substantially over the past decade. Pathologists' evaluation of parameters such as pathologic stage, histologic subtype, grade and microsatellite instability, and their identification of patients at risk for Lynch syndrome have become essential components of diagnosis, prognostic assessment and determination of optimal treatment of affected women. Despite the use of multimodality treatment and combination cytotoxic chemotherapy, the prognosis of women with advanced-stage gynecologic cancer is often poor. Therefore, expanding the arsenal of available systemic therapies with targeted therapeutic agents is appealing. Anti-angiogenic therapies, immunotherapy and poly ADP ribose polymerase (PARP) inhibitors are now routinely used for the treatment of advanced gynecologic cancer, and many more are under investigation. Pathologists remain important in the clinical management of patients with targeted therapy, by identifying potentially targetable tumors on the basis of their pathologic phenotype, by assessing biomarkers that are predictive of response to targeted therapy (e.g. microsatellite instability, PD1/PDL1 expression), and by monitoring treatment response and resistance. Pathologists are also vital to research efforts exploring novel targeted therapies by identifying homogenous subsets of tumors for more reliable and meaningful analyses, and by confirming expression in tumor tissues of novel targets identified in genomic, epigenetic or other screening studies. In the era of precision gynecologic oncology, the roles of pathologists in the discovery, development and implementation of targeted therapeutic strategies remain as central as they are for traditional (surgery-chemotherapy-radiotherapy) management of women with gynecologic cancers. PMID- 29174568 TI - Small bowel adenocarcinoma: French intergroup clinical practice guidelines for diagnosis, treatments and follow-up (SNFGE, FFCD, GERCOR, UNICANCER, SFCD, SFED, SFRO). AB - BACKGROUND: This document is a summary of the French intergroup guidelines regarding the management of small bowel adenocarcinoma published in October 2016. METHOD: This collaborative work, co-directed by most French Medical Societies, summarizes clinical practice recommendations (guidelines) on the management of small bowel adenocarcinoma. Given the lack of specific data in the literature, all references are given by analogy with colon cancer. The classification used is the AJCC (American Joint Committee on Cancer) pTNM classification (7th edition 2009). RESULTS: Small bowel adenocarcinoma has a poor prognosis; less than 30% of patients survive for 5 years after the (first) diagnosis (5-year survival of less than 30%). Due to the rarity of the disease and the retrospective data, most recommendations are based on expert agreement. The initial evaluation is based on chest-abdomen-pelvis CT scan, CEA assay, GI endoscopy and colonoscopy in order detect lesions associated with a predisposing disease. Surgical treatment is currently the only curative option for stage I and II. Adjuvant chemotherapy can be discussed for Stage III and Stage II with T4 (expert agreement). With regard to metastatic tumors, treatment with fluoropyrimidine combined with platinum salts should be considered (expert agreement). CONCLUSION: Few specific data exist in the literature on this type of tumor; most of the recommendations come from expert agreements or by analogy with colon cancer. Thus, each case must be discussed within a multidisciplinary team. PMID- 29174569 TI - A modified Poisson-Boltzmann equation applied to protein adsorption. AB - Ion-exchange chromatography has been widely used as a standard process in purification and analysis of protein, based on the electrostatic interaction between the protein and the stationary phase. Through the years, several approaches are used to improve the thermodynamic description of colloidal particle-surface interaction systems, however there are still a lot of gaps specifically when describing the behavior of protein adsorption. Here, we present an improved methodology for predicting the adsorption equilibrium constant by solving the modified Poisson-Boltzmann (PB) equation in bispherical coordinates. By including dispersion interactions between ions and protein, and between ions and surface, the modified PB equation used can describe the Hofmeister effects. We solve the modified Poisson-Boltzmann equation to calculate the protein-surface potential of mean force, treated as spherical colloid-plate system, as a function of process variables. From the potential of mean force, the Henry constants of adsorption, for different proteins and surfaces, are calculated as a function of pH, salt concentration, salt type, and temperature. The obtained Henry constants are compared with experimental data for several isotherms showing excellent agreement. We have also performed a sensitivity analysis to verify the behavior of different kind of salts and the Hofmeister effects.

AB - An easy to handle high-performance liquid chromatography (HPLC) method for the separation of structural isomers of short-chain aldehydes as their hydrazones is presented. Some aldehydes were not available as reference compounds, therefore, synthesis routes for these hydroxy-aldehydes and their dinitrophenylhydrazone derivatives are reported. The reported method has a detection limit of 2.4 16.1MUg/L for the hydrazones and shows good linearity and reproducibility for various tested aldehydes. PMID- 29174571 TI - A chromatographic study on the exceptional chiral recognition of 2 (benzylsulfinyl)benzamide by an immobilized-type chiral stationary phase based on cellulose tris(3,5-dichlorophenylcarbamate). AB - In previous studies, Okamoto et al. described the results of the exceptionally large chiral recognition of 2-(benzylsulfinyl)benzamide onto a coated-type chiral stationary phase based on cellulose tris(3,5-dichlorophenylcarbamate). As a continuation and deepening of those studies, here the sulfoxide and a small set of its structural analogues were analyzed on the commercially available Chiralpak IC-3 chiral stationary phase based upon the same polysaccharide derivative as the chiral selector but immobilized onto silica support. The chromatographic results obtained using different mobile phases consisting of pure methanol, ethanol and 2 propanol or binary mixtures n-hexane-2-propanol, which are prohibited with the progenitor coated-type chromatographic support, permitted to identify the NH2 of the amide group as the key structural element of the (S)-enantiomer of 2 (benzylsulfinyl)benzamide for obtaining a very high affinity for the IC-3 chiral stationary phase. PMID- 29174572 TI - Applications of 2, 2, 2 trifluoroethanol as a versatile co-solvent in supercritical fluid chromatography for purification of unstable boronate esters, enhancing throughput, reducing epimerization, and for additive free purifications. AB - Analysis and purification of boronic acid pinacol esters by RPLC is very challenging due to their degradation in aqueous and alcoholic solvents. These compounds are difficult to purify by SFC too as they are equally sensitive to traditional co-solvents like methanol, ethanol, and 2-propanol. 2,2,2 trifluoroethanol (TFE), which has been reported for the purification of a few alcohol sensitive compounds, was evaluated as a co-solvent in this study for the purification of chiral and achiral boronate esters by SFC. Examples of twelve compounds were presented in this paper where degradation of boronic acid pinacol esters was successfully controlled by replacing methanol with TFE as the co solvent in SFC. A separate study showed that TFE can also control the epimerization of the enantiomers of 3 substituted 1,4 benzodiazepine analogues during the purification process. In addition to above benefits, 2,2,2trifloroethanol showed improved selectivity and resolution for most of the compounds. With its stronger solvent strength compared to other alcohols, TFE could also be used to reduce the co-solvent percentage needed for elution and to shorten retention time of highly polar samples which did not elute even in 50% of other co-solvents in SFC. A case study of compound B demonstrated that TFE provided a reduced co-solvent percentage and a shorter cycle time with much improved resolution as compared to methanol, thus resulting in higher loading and throughput with reduction of total solvent consumption.

PMID- 29174574 TI - Enhanced neurogenesis in degenerated hippocampi following pretreatment with miR 302/367 expressing lentiviral vector in mice. AB - Astrogliosis is the main landmark of neurodegenerative diseases. In vivo reprogramming of reactive astrocytes to functional neurons opened a new horizon in regenerative medicine. However there is little evidence that show possible application of in vivo reprogramming approaches for enhancement of neurogenesis. Cluster miR-302/367 showed high capability in cell reprogramming. Here we show that application of lentiviral particles expressing cluster miR-302/367 along with systemic valproate (VPA) enhanced the capability of mice brains for neurogenesis in CA3 area following kainic acid (KA) induced hippocampal neurodegeneration. Following pretreatment with miR-302/367 expressing viral particles and VPA, transduced cells showed neuroblast and mature neuron markers when neuronal loss was induced by KA. Comparing the neuron counts in CA3 region also showed that neurogenesis was increased in CA3 region in animals which were pretreated with miR-302/367 vector and VPA, only in injected side of the brain. Our data suggest that targeted application of miR-302/367 expressing vector may enhance the capacity of hippocampus and other brain structures for regeneration following neuronal loss. PMID- 29174575 TI - Obeticholic acid protects mice against lipopolysaccharide-induced liver injury and inflammation. AB - BACKGROUND: Cholestasis, as a main manifestation, induces liver injury during sepsis. The farnesoid X receptor (FXR) plays an important role in regulating bile acid homeostasis. Whether FXR activation by its agonist obeticholic acid (OCA) is contributed to improve sepsis-induced liver injury remains unknown. OBJECTIVE: The aim of the present study was to investigate the effect of OCA on lipopolysaccharide (LPS)-induced acute liver injury in mice. RESULTS: 8-week old male C57BL/6J mice were randomly divided into control group, LPS group, oral OCA group and LPS plus oral OCA (LPS + OCA) group. The serum and livers were collected for further analysis. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bile acid (TBA) and total bilirubin (TBIL) were measured at indicated time after LPS administration. Liver sections were stained with hematoxylin & eosin (H&E). Orally OCA pretreatment stimulated the expression of FXR and BSEP in livers and protected mice from LPS-induced hepatocyte apoptosis and inflammatory infiltration. Consistently, LPS-induced higher serum levels of ALT, AST, TBA and TBIL were significantly reversed by OCA administration. Meanwhile, the mRNA levels of interleukin 1beta (IL-1beta), tumor necrosis factor alpha (TNF-alpha) and IL-6 were decreased in livers of mice in LPS + OCA group compared with LPS group. Further investigation indicated that the higher expression of ATF4 and LC3II/I were associated with the protective effect of OCA on LPS-induced liver injury. CONCLUSION: Orally OCA pretreatment protects mice from LPS-induced liver injury possibly contributed by improved bile acid homeostasis, decreased inflammatory factors and ATF4-mediated autophagy activity in hepatocytes. PMID- 29174576 TI - DNA binding and Topoisomerase inhibition: How can these mechanisms be explored to design more specific anticancer agents? AB - DNA is considered one of the most promising targets of molecules with anticancer activity potential. Its key role in various cell division mechanisms, which commands the intense multiplication of tumor cells, is considered in studies with compounds whose mechanisms of action suggest likeliness of interaction. In addition, inhibition of enzymes that actively participate in biological functions of cells such as Topoisomerase, is seen as a primary factor for conducting several events that result in cell death. Discovery of new anticancer chemotherapeutical capable of interacting with DNA and inhibiting Topoisomerase enzymes is highlighted in anticancer research. The present review aims at showing through distinct biological tests the performance of different candidates to anticancer drugs and their respective chemical modifications, which are crucial and/or determinant for DNA affinity and inhibition of important enzymes in cells' vital processe to either separately or synergistically optimize anticancer activity. PMID- 29174577 TI - Caffeic acid and licochalcone A interfere with the glyoxylate cycle of Trichophyton rubrum. AB - Trichophyton rubrum is the most common causative agent of dermatomycoses worldwide. Despite the increasing incidence of fungal infections, the number of commercially available antifungal drugs is limited, mainly because of the biochemical similarities between fungal and mammalian cells. Biomolecules of different origins might lead to the discovery of new pharmacological targets that are more specific to the fungal cell. In this respect, caffeic acid (CA) and licochalcone A (LicoA) exhibit activity against some human pathogenic fungi by acting on important fungal molecular targets. The glyoxylate cycle is involved in the adaptation of fungal cells inside the human cell and is well established for some fungi of clinical interest. Activation of this cycle is related to the survival of fungi in nutrient-limited environments. However, little is known about the involvement of the glyoxylate cycle in this process in dermatophytes. The objective of this study was to evaluate the antifungal activity of CA and LicoA against T. rubrum, investigating specifically the effect of these compounds on important antifungal targets such as ergosterol synthesis, cell wall and glyoxylate cycle. The minimum inhibitory concentration was 86.59 MUM for CA and 11.52 MUM for LicoA. Plasma membrane damage and a reduction in ergosterol levels were observed after the exposure of T. rubrum to CA, but not to LicoA. Evaluation of gene expression in T. rubrum co-cultured with human keratinocytes (HaCat) in the absence of the antifungal compounds showed induction of genes related to the ergosterol biosynthesis pathway and genes encoding enzymes involved in cell wall synthesis and in the glyoxylate cycle. The same genes were significantly repressed after exposure of the co-culture to subinhibitory concentrations of CA and LicoA. The enzymatic activity of isocitrate lyase was reduced in the presence of LicoA and a moderate reduction was observed in the presence of CA. These results indicate that CA and LicoA act on targets that play important roles in pathogen-host interactions, in antifungal activity and, especially, in the glyoxylate cycle.

PMID- 29174580 TI - A Systematic Review and Meta-analysis Comparing the Efficacy of Nonsteroidal Anti inflammatory Drugs, Opioids, and Paracetamol in the Treatment of Acute Renal Colic. AB - CONTEXT: Renal colic is a common, acute presentation of urolithiasis that requires immediate pain relief. European Association of Urology guidelines recommend nonsteroidal anti-inflammatory drugs (NSAIDs) as the preferred analgesia. However, the fear of NSAID adverse effects and the uncertainty about superior analgesic effect have maintained the practice of advocating intravenous opioids as the initial analgesia. OBJECTIVE: The objective of this systematic review and meta-analysis was to compare the safety and efficacy of NSAIDs with opioids and paracetamol (acetaminophen) for the management of acute renal colic. EVIDENCE ACQUISITION: Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, World Health Organization International Clinical Trials Registry Platform, Google Scholar, and the reference list of retrieved articles were searched up to December 2016 without language restrictions. Two reviewers independently assessed eligible studies using the Cochrane Collaboration tool for assessing and reporting the risk of bias and abstracted data using predefined data fields. EVIDENCE SYNTHESIS: From 468 potentially relevant studies, 36 randomized controlled trials (RCTs) including 4887 patients, published between 1982 and 2016, were included in this systematic review. The treatment effect observed indicated marginal benefit of NSAIDs over opioids in initial pain reduction at 30min (11 RCTs, n=1985, mean difference [MD] -5.58, 95% confidence interval [CI] -10.22 to -0.95; heterogeneity I2=81%). In the subgroup analyses by the route of administration, NSAIDs required fewer rescue treatments (seven RCTs, n=541, number needed to treat [NNT] 11, 95% CI 6-75) and had lower vomiting rates compared with opioids (five RCTs, n=531, NNT 5, 95% CI 4-8). Comparisons of NSAIDs with paracetamol showed no difference for both drugs at 30min (four RCTs, n=1325, MD -5.67, 95% CI -17.52 to 6.18, p=0.35; I2=89%). Patients treated with NSAIDs required fewer rescue treatments (two trials, n=1145, risk ratio 0.56, 95% CI 0.42-0.74, p<0.001; I2=0%). CONCLUSIONS: NSAIDs were equivalent to opioids or paracetamol in the relief of acute renal colic pain at 30min. There was less vomiting and fewer requirements for rescue analgesia with NSAIDs compared with opioids. Patients treated with NSAIDs required less rescue analgesia compared with paracetamol. Despite observed heterogeneity among the included studies and the overall quality of evidence, the findings of a lower need for rescue analgesia and fewer adverse events, in conjunction with the practical advantages of ease of delivery, suggest that NSAIDs should be the preferred analgesic option for patients presenting to the emergency department with renal colic. PATIENT SUMMARY: In kidney stone-related acute pain episodes in patients with adequate renal function, treatment with nonsteroidal anti-inflammatory drugs offers effective and most sustained pain relief, with fewer side effects, when compared with opioids or paracetamol. PMID- 29174581 TI - Comparison of lung diffusing capacity in young elite athletes and their counterparts. AB - BACKGROUND: The influence of exercise on the pulmonary function is controverse, some studies have reported no sports influence, while the others have found positive correlation. AIM: To evaluate and compare the sports influence on pulmonary function: spirometry (VC, FVC, FEV1, FEV1/FVC), lung diffusing capacity (DLCO) and coefficient of the CO gas transfer (KCO) in two elite athletes groups and healthy sedentary controls. METHOD: Equally divided into aerobic and anaerobic group, 60 elite athletes were recruited, as well as 43 age-matched, healthy sedentary controls. All of the participants performed basic anthropometric measurements, spirometry, DLCO and KCO at rest. Kruskal-Wallis one way ANOVA test was used to determine differences between groups; Mann-Whitney U test was used for inter-groups differences and Pearson coefficient for pulmonary variables and anthropometric parameters correlation. Statistical analyses were performed using the SPSS computer statistic program, version 20. RESULTS: No differences were found in pulmonary characteristics (spirometric function values, DLCO and KCO) in athletes and non-athletes at rest, as well as between aerobics and anaerobics. There were no correlations between the anthropometric parameters and the investigated respiratory function tests. DLCO (%) correlated positively with height in athletes playing anaerobic type of sport (karate and taekwondo) (p=0.036; r=0.544), and negatively in sedentary control group (p=0.030; r= 0.560). Regarding KCO, no differences were found. CONCLUSION: Spirometry indices and DLCO are not influenced either by aerobic or anaerobic training type, so benefits of sports on pulmonary indices or DLCO was not confirmed. PMID- 29174582 TI - Macitentan in daily clinical practice: A single centre, 1-year experience. AB - The effectiveness and safety of macitentan, a dual endothelin-receptor antagonist (ERA) approved for the treatment of pulmonary arterial hypertension (PAH), were shown in an extensive clinical trial oriented towards morbidity and mortality events. Our aim was to describe a single centre's experience of the utilization of macitentan in patients with PAH in clinical practice settings. Thirteen patients with different aetiologies and previous PAH treatments were studied. After 12 months of macitentan treatment, 11 patients improved their functional class (FC), all patients improved their 6-minute walk distance (6MWD) test, and 10 patients lowered their NT-proBNP plasma levels. Additionally, cardiac imaging parameters were also improved. No cases resulted in hospitalization, septostomy, transplant or death. PMID- 29174583 TI - The protective effects of whortleberry extract against cisplatin-induced ototoxicity in rats. AB - INTRODUCTION: Cisplatin is one of the main chemotherapeutic agents used for the treatment of many types of cancer. However, ototoxicity, one of the most serious side effects of cisplatin, restricts its usage. OBJECTIVE: We aimed to investigate the protective effects of whortleberry extract against cisplatin induced ototoxicity by evaluating hearing and histopathological cochlear damage and by measuring the biochemical parameters affected byoxidative stress. METHODS: Forty-eight male rats were included in the study after performing Distortion Product Otoacoustic Emission test to confirm that their hearing levels were normal. The rats were randomly divided into six groups: the control group, the sham group, and, which received only whortleberry extract, only cisplatin, cisplatin+100mg whortleberry extract, cisplatin+200mg whortleberry extract, respectively. Audiologic investigation was performed by performing the Distortion Product Otoacoustic Emission test at the beginning and at the eighth day of the study. Cardiac blood samples were collected for biochemical analysis, and the rats were sacrificed to obtain cochlear histopathological specimens on the eighth day. RESULTS: The results revealed that whortleberry protects hearing against cisplatin-induced ototoxicity independent of the dose. However, high doses of whortleberry extract are needed to prevent histopathological degeneration and oxidative stress. CONCLUSION: The results obtained in this study show that whortleberry extract has a protective effect against cisplatin-induced ototoxicity.

AB - INTRODUCTION: A large number of people around the world struggle daily to become free of their addiction to illegal psychoactive substances. In order to create an atmosphere of improved supervision, established communication and improved quality of life for drug addicts, centers have been set up to provide methadone as a substitute. OBJECTIVE: The aim of the research was to assess the vocal features of drug addicts on methadone therapy via subjective and objective parameters, to ascertain if vocal damage has occurred and to determine whether subjective and objective acoustic vocal parameters are related, and how. METHODS: The research included 34 adults of both genders who were undergoing methadone treatment. A subjective vocal evaluation assessed voice pitch and clarity, while the subjective acoustic analysis utilized the Roughness-Breathiness-Hoarseness scale of roughness-breathiness-hoarseness. Objective acoustic analysis was conducted after recording and analyzing an uninterrupted vocal /a/ of at least three seconds duration, using the "GllotisController" software. RESULTS: The subjective acoustic analysis using the Roughness-Breathiness-Hoarseness scale showed pathological values in 52.9% male and 47% female participants. The average values of the roughness-breathiness-hoarseness for the entire sample were 0.91, 0.38 and 0.50, respectively. Lower roughness was associated with a higher fundamental frequency (f0) and lower jitter and shimmer values (p<0.05). There was a statistically significant correlation between breathiness, jitter (p<0.01) and shimmer (p<0.05), and between hoarseness and jitter (p<0.01). CONCLUSION: A statistically significant correlation was found between the two subjective vocal assessments, voice clarity and pitch, and Roughness-Breathiness-Hoarseness scale, and the parameters of the objective acoustic vocal assessment.

AB - Pulmonary hypertension continues to be a life-threatening illness with debilitating physical and emotional consequences affecting around 1% of global population. The progression of this devastating disease is characterized by increase in pulmonary vascular resistance resulting in elevated pulmonary pressure, eventually leading to right heart failure and death. Better understanding of pathophysiology has led to substantial improvements in terms of availability of treatment options. The purpose of this review is to summarize the currently available treatment options along with pertinent trials and possible future therapies of pulmonary arterial hypertension.

PMID- 29174587 TI - Effects of mesenchymal stromal cells play a role the oxidant/antioxidant balance in a murine model of asthma. AB - Asthma is a heterogeneous disease characterised by chronic airway inflammation. One of the most devastating consequences of this inflammatory process is the generation of reactive oxygen and nitrogen species responsible for oxidative stress. The aim of this study is to analyse the efficiency of treatment with human bone marrow-derived mesenchymal stromal cells (hMSC) in maintaining the oxidative balance in a murine model of allergic asthma by quantifying nitrotyrosine in lung tissues. After confirmation of asthma in the experimental model, samples of lung parenchyma were submitted to immunohistochemical assessment. Intravenous administration of hMSC reduced the levels of nitrotyrosine in the ASTHMA-hMSC group compared to those in the ASTHMA-SAL group. In conclusion, therapeutic administration of hMSC had a beneficial effect on oxidative stress, reducing the levels of nitrotyrosine in lung tissues in a model of allergic asthma. PMID- 29174588 TI - Trimethylene carbonate-caprolactone conduit with poly-p-dioxanone microfilaments to promote regeneration after spinal cord injury. AB - : Spinal cord injury (SCI) is often associated with scarring and cavity formation and therefore bridging strategies are essential to provide a physical substrate for axonal regeneration. In this study we investigated the effects of a biodegradable conduit made from trimethylene carbonate and epsilon-caprolactone (TC) containing poly-p-dioxanone microfilaments (PDO) with longitudinal grooves on regeneration after SCI in adult rats. In vitro studies demonstrated that different cell types including astrocytes, meningeal fibroblasts, Schwann cells and adult sensory dorsal root ganglia neurons can grow on the TC and PDO material. For in vivo experiments, the TC/PDO conduit was implanted into a small 2-3 mm long cavity in the C3-C4 cervical segments immediately after injury (acute SCI) or at 2-5 months after initial surgery (chronic SCI). At 8 weeks after implantation into acute SCI, numerous 5HT-positive descending raphaespinal axons and sensory CGRP-positive axons regenerated across the conduit and were often associated with PDO microfilaments and migrated host cells. Implantation into chronically injured SCI induced regeneration mainly of the sensory CGRP-positive axons. Although the conduit had no effect on the density of OX42-positive microglial cells when compared with SCI control, the activity of GFAP-positive astrocytes was reduced. The results suggest that a TC/PDO conduit can support axonal regeneration after acute and chronic SCI even without addition of exogenous glial or stem cells. STATEMENT OF SIGNIFICANCE: Biosynthetic conduits can support regeneration after spinal cord injury but often require addition of cell therapy and neurotrophic factors. This study demonstrates that biodegradable conduits made from trimethylene carbonate and epsilon-caprolactone with poly-p dioxanone microfilaments alone can promote migration of different host cells and stimulate axonal regeneration after implantation into acute and chronic spinal cord injury. These results can be used to develop biosynthetic conduits for future clinical applications. PMID- 29174589 TI - Focal adhesion signaling affects regeneration by human nucleus pulposus cells in collagen- but not carbohydrate-based hydrogels. AB - : Hydrogel-based 3D cell cultures are an emerging strategy for the regeneration of cartilage. In an attempt to regenerate dysfunctional intervertebral discs, nucleus pulposus (NP) cells can be cultured in hydrogels of various kinds and physical properties. Stiffness sensing through focal adhesions is believed to direct chondrogenesis, but the mechanisms by which this works are largely unknown. In this study we compared focal adhesion formation and glycosaminoglycan (GAG) deposition by NP cells in a range of hydrogels. Using a focal adhesion kinase (FAK) inhibitor, we demonstrated that focal adhesion signaling is involved in the response of NP cells in hydrogels that contain integrin binding sites (i.e. methacrylated gelatin (gelMA) and type II collagen), but not in hydrogels deplete from integrin binding sites such as alginate and agarose, or CD44-binding hydrogels based on hyaluronic acid. As a result of FAK inhibition we observedenhanced proteoglycan production in gelMA, but decreased production in type II collagen hydrogels, which could be explained by alteration in cell fate as supported by the increase in the adipogenic marker peroxisome proliferator activated receptor gamma (PPARy). Furthermore, GAG deposition was inversely proportional to polymer concentration in integrin-binding gelMA, while no direct relationship was found for the non-integrin binding gels alginate and agarose. This corroborates our finding that focal adhesion formation plays an important role in NP cell response to its surrounding matrix. STATEMENT OF SIGNIFICANCE: Biomaterials are increasingly being investigated for regenerative medicine applications, including regeneration of the nucleus pulposus. Cells interact with their environment and are influenced by extracellular matrix or polymer properties. Insight in these interactions can improve regeneration and helps to understand degeneration processes. The role of focal adhesion formation in the regenerative response of nucleus pulposus cells is largely unknown. Therefore, the relation between materials, stiffness and focal adhesion formation is studied here.

AB - A 4-week-old American Quarter Horse colt presented with a recent history of diarrhea and decreased activity level. On initial physical examination, the animal was bright and alert and major findings were limited to a loud systolic heart murmur radiating widely over both sides of the thorax. While in the hospital, the clinical condition of the foal warranted further imaging to determine the cause and extent of cardiac disease. A variety of congenital cardiac malformations were identified during echocardiographic examination and autopsy, including a double outlet right ventricle and a subpulmonary interventricular septal defect (Taussig-Bing anomaly), ventricular inversion with atrioventricular discordance, tricuspid valve atresia, a septum primum interatrial septal defect, mitral valve dysplasia with a cleft in the septal mitral valve cusp, aortic, and subaortic stenosis, tubular hypoplasia of the ascending aorta and the aortic arch, a patent ductus arteriosus, an aberrant circumflex coronary artery, and aberrant left and right subclavian arteries. Echocardiographic and postmortem findings of the cardiac defects in this foal are presented and discussed. PMID- 29174591 TI - Antidepressants Rescue Stress-Induced Disruption of Synaptic Plasticity via Serotonin Transporter-Independent Inhibition of L-Type Calcium Channels. AB - BACKGROUND: Long-term synaptic plasticity is a basic ability of the brain to dynamically adapt to external stimuli and regulate synaptic strength and ultimately network function. It is dysregulated by behavioral stress in animal models of depression and in humans with major depressive disorder. Antidepressants have been shown to restore disrupted synaptic plasticity in both animal models and humans; however, the underlying mechanism is unclear. METHODS: We examined modulation of synaptic plasticity by selective serotonin reuptake inhibitors (SSRIs) in hippocampal brain slices from wild-type rats and serotonin transporter (SERT) knockout mice. Recombinant voltage-gated calcium (Ca2+) channels in heterologous expression systems were used to determine the modulation of Ca2+ channels by SSRIs. We tested the behavioral effects of SSRIs in the chronic behavioral despair model of depression both in the presence and in the absence of SERT. RESULTS: SSRIs selectively inhibited hippocampal long-term depression. The inhibition of long-term depression by SSRIs was mediated by a direct block of voltage-activated L-type Ca2+ channels and was independent of SERT. Furthermore, SSRIs protected both wild-type and SERT knockout mice from behavioral despair induced by chronic stress. Finally, long-term depression was facilitated in animals subjected to the behavioral despair model, which was prevented by SSRI treatment. CONCLUSIONS: These results showed that antidepressants protected synaptic plasticity and neuronal circuitry from the effects of stress via a modulation of Ca2+ channels and synaptic plasticity independent of SERT. Thus, L-type Ca2+ channels might constitute an important signaling hub for stress response and for pathophysiology and treatment of depression.

PMID- 29174594 TI - Prediction of filamentous process performance attributes by CSL quality assessment using mid-infrared spectroscopy and chemometrics. AB - Every biopharmaceutical production process aims for control strategies to achieve process robustness in order to ensure consistent product quality. Process variability can origin from process parameters, the biological nature as well as from high lot-to-lot variability of raw materials. In filamentous processes raw materials with very complex matrices, such as corn steep liquor (CSL), are used, which are especially challenging to characterize. In this study, CSL was characterized in detail for its ingredients presenting an overall composition of its matrix of 50 analyzed components (19 amino acids, 5 organic acids, 8 reducing sugars, 7 water-soluble vitamins and 11 trace elements/minerals) in order to facilitate analytical reduction to fingerprinting methods FT-MIR was evaluated as fast and non-destructive spectroscopic fingerprinting method for adequate assessment of CSL quality. Feasibility of this method was shown by the correlation of certain bands in the spectra to substance groups present in CSL, such as the Amide I and II band and amino acids, respectively. Additionally, applicability of FT-MIR could be shown for classification of different CSL lots differing in provider and corn quality as well as for predictability of process performance attributes. The latter was demonstrated on a fed-batch filamentous fungi process for the production of antibiotics. By multivariate data analysis, it could be shown that CSL quality assessment via FT-MIR can be used for the prediction of maximal biomass generated in the process, with a correlation coefficient R2 of 0.964, as well as for the prediction of an unwanted impurity. The combination of a fast and easy method for CSL quality assessment and correlations of this quality with process performance attributes may facilitate the establishment of a risk-based acceptance criteria for raw material quality release of CSL. As CSL is a frequent used raw material, we believe that this method will also be useful for other processes and that CSL quality assessment is of high relevance in academia and industry. PMID- 29174595 TI - Impact of everolimus-eluting stent length on long-term clinical outcomes of percutaneous coronary intervention. AB - BACKGROUND: Even though longer stented lengths may increase the risk of restenosis, full coverage of diffuse long lesions with longer stents seems to be the optimal strategy for percutaneous coronary intervention (PCI) in the new drug eluting stent (DES) era. However, it remains unclear whether this strategy will indicate favorable outcome or not. This study evaluated the impact of stent length on two-year clinical outcomes after PCI with the XIENCE Alpine everolimus eluting stent. METHODS: This was a retrospective, non-randomized, observational study. Four patient groups were classified according to implanted overall total stent length (short, <15mm; middle, 15-23mm; long, 24-32mm; and ultra-long, >32mm). The primary outcome of this study was major adverse cardiac events (MACE), defined as the composite of cardiac death, recurrent myocardial infarction (MI), target vessel revascularization (TVR), and stent thrombosis (ST). Angiographic restenosis by quantitative coronary angiography was defined as >50% diameter stenosis at 10 months after PCI. RESULTS: A total of 730 patients who received intravascular ultrasound (IVUS)-guided PCI were enrolled. The short, middle, long, and ultra-long stent groups included 138 patients (149 lesions), 210 patients (235 lesions), 190 patients (209 lesions), and 192 patients (208 lesions), respectively. The primary outcome at two years did not differ among the four groups (MACE: 4.4% in short, 3.3% in middle, 4.7% in long, and 4.7% in ultra long groups, p=0.402); TVR, ST, MI, and cardiac mortality also did not differ among groups. CONCLUSIONS: Long stenting using the XIENCE stent which was guided by IVUS for diffuse, long lesions was associated with favorable clinical outcomes at two years in daily clinical practice.

AB - BACKGROUND: The earliest white matter changes in Huntington's disease are seen before disease onset in the premanifest stage around the striatum, within the corpus callosum, and in posterior white matter tracts. While experimental evidence suggests that these changes may be related to abnormal gene transcription, we lack an understanding of the biological processes driving this regional vulnerability. METHODS: Here, we investigate the relationship between regional transcription in the healthy brain, using the Allen Institute for Brain Science transcriptome atlas, and regional white matter connectivity loss at three time points over 24 months in subjects with premanifest Huntington's disease relative to control participants. The baseline cohort included 72 premanifest Huntington's disease participants and 85 healthy control participants. RESULTS: We show that loss of corticostriatal, interhemispheric, and intrahemispheric white matter connections at baseline and over 24 months in premanifest Huntington's disease is associated with gene expression profiles enriched for synaptic genes and metabolic genes. Corticostriatal gene expression profiles are predominately associated with motor, parietal, and occipital regions, while interhemispheric expression profiles are associated with frontotemporal regions. We also show that genes with known abnormal transcription in human Huntington's disease and animal models are overrepresented in synaptic gene expression profiles, but not in metabolic gene expression profiles. CONCLUSIONS: These findings suggest a dual mechanism of white matter vulnerability in Huntington's disease, in which abnormal transcription of synaptic genes and metabolic disturbance not related to transcription may drive white matter loss. PMID- 29174598 TI - Acute coronary syndrome - Still a valid contraindication to perform rotational atherectomy? Early and one-year outcomes. AB - BACKGROUND: Rotational atherectomy (RA) is an acknowledged method of percutaneous treatment of highly calcified or fibrotic coronary lesions. However, using the rotablator system in patients presenting with acute coronary syndromes (ACS) remains controversial and is considered as a relative contraindication. The aim of our study was to assess in-hospital and 1-year outcomes in patients undergoing RA presenting with ACS, in comparison to elective RA procedures. METHODS: This single-center observational study included all consecutive patients who underwent RA and PCI in our institution from April 2008 to October 2015. All patients were subsequently divided into two groups based on clinical presentation: stable angina group (SA) and ACS group. Primary endpoints were in-hospital and 1-year all-cause mortality and 1-year major adverse cardiac events (MACE). Secondary endpoints were procedural success and in-hospital complications. RESULTS: The study included 207 patients, 164 (79%) in SA group and 43 (21%) in ACS group. In hospital mortality was higher in patients with ACS (4.7% vs. 0%, p=0.01). Procedural success was similar in both groups, 93% in ACS groups vs. 92.7% in SA group, p=0.94. There were no significant differences in the rate of periprocedural complications (4.7% vs. 10.4%, p=0.25), however postprocedural complications were more frequent in ACS group. At 1-year follow-up MACE rate and mortality were numerically higher, however statistically not significant (25.6% vs. 16.5%, p=0.17 and 16.3% vs. 7.9%, p=0.10; respectively). CONCLUSIONS: Despite higher mortality and complication rate in ACS group observed in postprocedural period, we found no significant difference in 1-year outcomes in comparison to elective patients. Procedural success of RA in ACS patients is similar to elective patients with SA and this procedure should be considered in case of urgent indications, if no other options of treatment exist. PMID- 29174597 TI - Intravascular hemolysis in patients with mitral regurgitation: Evaluation by erythrocyte creatine. AB - BACKGROUND: Intravascular hemolysis has been reported in patients with cardiac valve prostheses, but intravascular hemolysis in patients with mitral regurgitation with native valve has not been evaluated in detail. We designed a study to elucidate the impact of regurgitation flow on intravascular hemolysis in patients with primary mitral regurgitation by measuring erythrocyte creatine. METHODS: Erythrocyte creatine was enzymatically assayed in 29 patients with moderate to severe primary mitral regurgitation and 12 age-matched healthy volunteers. The size and characteristics of mitral regurgitation were determined by color Doppler echocardiography. RESULTS: Erythrocyte creatine was significantly higher in patients with eccentric jet (n=17, 2.64+/-0.77MUmol/g Hb) than that of central jet (n=12, 1.68+/-0.13MUmol/g Hb) and control subjects (1.39+/-0.25MUmol/g Hb). Patients with eccentric jet had a significantly lower erythrocyte count and hemoglobin (385+/-58 x104/MUL and 116+/-19g/l) compared to those with central jet (450+/-47*104/MUL and 137+/-14g/l) and control subjects (433+/-31*104/MUL and 134+/-19g/l). There were no significant differences in age, estimated glomerular filtration rate, pulmonary artery systolic pressure, left atrial size and left ventricular end-diastolic dimension between patients with eccentric jet and central jet. CONCLUSIONS: Intravascular hemolysis associated with subclincal anemia in patients with eccentric jet was due to the destruction of erythrocyte by collision of the eccentric jet to the atrial wall. PMID- 29174599 TI - Strategy of delayed surgery for ventricular septal perforation after acute myocardial infarction. AB - BACKGROUND: The timing of surgical repair for ventricular septal perforation (VSP) is important because patients are susceptible to bleeding from fragile myocardial tissue or residual shunt during the acute phase of acute myocardial infarction (AMI). This study aimed to assess the results of delayed surgery for VSP performed 2 weeks after AMI. METHODS: In total, 24 consecutive postinfarction patients with VSP (mean age: 72.6+/-10.4 years; 13 males) underwent operation between May 2003 and June 2016. We postponed surgery during the acute phase and performed an elective surgery if the patient could wait for 2 weeks with support from intra-aortic balloon pumping (IABP) and respiratory management. If we could not control heart failure and organ function worsened during that period, we performed emergency surgery. Postoperative outcomes included complications, 30 day mortality rate, long-term hospital death, reoperation rate, and risk factors for hospital mortality. We examined whether organ function was maintained by delaying the surgery. RESULTS: Of the 24 patients, 11 (45.8%) required emergency surgery, and 13 (54.2%) could wait 2 weeks for surgery. The average time from AMI onset to diagnosis of VSP was 4.5+/-1.6 days, and the average time from VSP diagnosis to surgery was 9.0+/-6.0 days; 5 patients (20.8%) required resurgery for VSP due to residual shunt, recurrent VSP, or pseudoaneurysm of the left ventricle. The 30-day mortality rate was 4.2% (1 patient), and long-term hospital mortality rate was 12.5% (3 patients). Organ function was maintained in 10 patients (76.9%) who underwent elective surgery, and organ dysfunction was not advanced by delaying the surgery. CONCLUSIONS: We could delay surgery for an average of 9 days from VSP onset by means of IABP or respiratory management without the deterioration of organ function. The 30-day mortality and long-term outcome were favorable. PMID- 29174600 TI - Hybrid combinations containing natural products and antimicrobial drugs that interfere with bacterial and fungal biofilms. AB - BACKGROUND: Biofilms contribute to the pathogenesis of many chronic and difficult to eradicate infections whose treatment is complicated due to the intrinsic resistance to conventional antibiotics. As a consequence, there is an urgent need for strategies that can be used for the prevention and treatment of biofilm associated infections. The combination therapy comprising an antimicrobial drug with a low molecular weight (MW) natural product and an antimicrobial drug (antifungal or antibacterial) appeared as a good alternative to eradicate biofilms. PURPOSE: The aims of this review were to perform a literature search on the different natural products that have showed the ability of potentiating the antibiofilm capacity of antimicrobial drugs, to analyze which are the antimicrobial drugs most used in combination, and to have a look on the microbial species most used to prepare biofilms. RESULTS: Seventeen papers, nine on combinations against antifungal biofilms and eight against antibacterial biofilms were collected. Within the text, the following topics have been developed: breaf history of the discovery of biofilms; stages in the development of a biofilm; the most used methodologies to assess antibiofilm-activity; the natural products with capacity of eradicating biofilms when acting alone; the combinations of low MW natural products with antibiotics or antifungal drugs as a strategy for eradicating microbial biofilms and a list of the low MW natural products that potentiate the inhibition capacity of antifungal and antibacterial drugs against biofilms. CONCLUSIONS AND PERSPECTIVES: Regarding combinations against antifungal biofilms, eight over the nine collected works were carried out with in vitro studies while only one was performed with in vivo assays by using Caenorhabditis elegans nematode. All studies use biofilms of the Candida genus. A 67% of the potentiators were monoterpenes and sesquiterpenes and six over the nine works used FCZ as the antifungal drug. The activity of AmpB and Caspo was enhanced in one and two works respectively. Regarding combinations against bacterial biofilms, in vitro studies were performed in all works by using several different methods of higher variety than the used against fungal biofilms. Biofilms of both the gram (+) and gram (-) bacteria were prepared, although biofilm of Staphylococcus spp. were the most used in the collected works. Among the discovered potentiators of antibacterial drugs, 75% were terpenes, including mono, di- and triterpenes, and, among the atibacterial drugs, several structurally diverse types were used in the combinations: aminoglycosides, beta lactams, glucopeptides and fluoroquinolones. The potentiating capacity of natural products, mainly terpenes, on the antibiofilm effect of antimicrobial drugs opens a wide range of possibilities for the combination antimicrobial therapy. More in vivo studies on combinations of natural products with antimicrobial drugs acting against biofilms are highly required to cope the difficult to treat biofilm associated infections. PMID- 29174601 TI - Food-derived 1,2-dicarbonyl compounds and their role in diseases. AB - Reactive 1,2-dicarbonyl compounds (DCs) are generated from carbohydrates during food processing and storage and under physiological conditions. In the recent decades, much knowledge has been gained concerning the chemical formation pathways and the role of DCs in food and physiological systems. DCs are formed mainly by dehydration and redox reactions and have a strong impact on the palatability of food, because they participate in aroma and color formation. However, they are precursors of advanced glycation end products (AGEs), and cytotoxic effects of several DCs have been reported. The most abundant DCs in food are 3-deoxyglucosone, 3-deoxygalactosone, and glucosone, predominating over methylglyoxal, glyoxal, and 3,4-dideoxyglucosone-3-ene. The availability for absorption of individual DCs is influenced by the release from the food matrix during digestion and by their reactivity towards constituents of intestinal fluids. Some recent works suggest formation of DCs from dietary sugars after their absorption, and others indicate that certain food constituents may scavenge endogenously formed DCs. First works on the interplay between dietary DCs and diseases reveal an ambiguous role of the compounds. Cancer-promoting but also anticancer effects were ascribed to methylglyoxal. Further work is still needed to elucidate the reactions of DCs during intestinal digestion and pathophysiological effects of dietary DCs at doses taken up with food and in "real" food matrices in disease states such as diabetes, uremia, and cancer.

PMID- 29174605 TI - Insecticidal activity of the metalloprotease AprA occurs through suppression of host cellular and humoral immunity. AB - The biochemical characterization of virulence factors from entomopathogenic bacteria is important to understand entomopathogen-insect molecular interactions. Pseudomonas entomophila is a typical entomopathogenic bacterium that harbors virulence factors against several insects. However, the molecular actions of these factors against host innate immune responses are not clearly elucidated. In this study, we observed that bean bugs (Riptortus pedestris) that were injected with P. entomophila were highly susceptible to this bacterium. To determine how P. entomophila counteracts the host innate immunity to survive within the insect, we purified a highly enriched protein with potential host insect-killing activity from the culture supernatant of P. entomophila. Then, a 45-kDa protein was purified to homogeneity and identified as AprA which is an alkaline zinc metalloprotease of the genus Pseudomonas by liquid chromatography mass spectrometry (LC-MS). Purified AprA showed a pronounced killing effect against host insects and suppressed both host cellular and humoral innate immunity. Furthermore, to show that AprA is an important insecticidal protein of P. entomophila, we used an aprA-deficient P. entomophila mutant strain (DeltaaprA). When DeltaaprA mutant cells were injected to host insects, this mutant exhibited extremely attenuated virulence. In addition, the cytotoxicity against host hemocytes and the antimicrobial peptide-degrading ability of the DeltaaprA mutant were greatly decreased. These findings suggest that AprA functions as an important insecticidal protein of P. entomophila via suppression of host cellular and humoral innate immune responses. PMID- 29174606 TI - Driving behavior recognition using EEG data from a simulated car-following experiment. AB - Driving behavior recognition is the foundation of driver assistance systems, with potential applications in automated driving systems. Most prevailing studies have used subjective questionnaire data and objective driving data to classify driving behaviors, while few studies have used physiological signals such as electroencephalography (EEG) to gather data. To bridge this gap, this paper proposes a two-layer learning method for driving behavior recognition using EEG data. A simulated car-following driving experiment was designed and conducted to simultaneously collect data on the driving behaviors and EEG data of drivers. The proposed learning method consists of two layers. In Layer I, two-dimensional driving behavior features representing driving style and stability were selected and extracted from raw driving behavior data using K-means and support vector machine recursive feature elimination. Five groups of driving behaviors were classified based on these two-dimensional driving behavior features. In Layer II, the classification results from Layer I were utilized as inputs to generate a k Nearest-Neighbor classifier identifying driving behavior groups using EEG data. Using independent component analysis, a fast Fourier transformation, and linear discriminant analysis sequentially, the raw EEG signals were processed to extract two core EEG features. Classifier performance was enhanced using the adaptive synthetic sampling approach. A leave-one-subject-out cross validation was conducted. The results showed that the average classification accuracy for all tested traffic states was 69.5% and the highest accuracy reached 83.5%, suggesting a significant correlation between EEG patterns and car-following behavior. PMID- 29174607 TI - Upregulation of SERT and ADORA1 in broilers with acute right ventricular failure. AB - Pulmonary hypertension (PH), remains a challenging disease with a large impact on both humans and meat-type chickens. PH is characterized by the onset of idiopathic pulmonary arterial hypertension leading to right ventricular failure. In this experiment relative gene expression of adenosine A1 receptor (ADORA1), serotonin transporter (SERT), phosphodiesterase 5A (PDE5) and troponin T2 were compared in hearts from broilers with acute right ventricular failure and from healthy birds. There were major increases in adenosine A1 receptor (177%) and serotonin transporter (475%), and more modest but significant increases in PDE5 (146%) and troponin T2 (140%) gene expressions in broilers with right ventricular failure compared to healthy birds (P<0.01). This novel report shows that pulmonary hypertension related gene expression in broilers is similar to that in humans. This molecular similarity between PH in broilers and human patients suggests, first, that they will make a suitable animal model for study PH in humans, but also that the literature on PH in humans may be profitably applied to the study of PH in broilers. PMID- 29174608 TI - Effect of surfactants and hydrophilic polymers on the stability of an antihypertensive drug candesartan cilexetil: Evaluation by HPLC. AB - OBJECTIVES: The objective of this study is to investigate the effect of surfactants (polysorbate 80 and sodium lauryl sulphate) and hydrophilic polymers (polyvinylpyrrolidone and polyethylene glycol 6000) on the stability of candesartan cilexetil under isothermal stress conditions (100 degrees C, 48h). METHODS: HPLC method was employed to evaluate the drug content and formation of degradation products in stress samples. Drug and degradation products were separated on Hypersil BDS C18 (250*4.6mm, 5MU) column using acetonitrile-water (pH 2.8) in the ratio of 85:15% v/v as a mobile phase. RESULT: Similar degradation behaviour of drug was observed with polyvinylpyrrolidone, polyethylene glycol 6000 and polysorbate 80; four common degradation peaks were observed at the retention time of 3.7, 4.5, 7.8 and 11minutes. One extra common degradation peak of very low intensity was also observed with polyethylene glycol 6000 and polysorbate 80 at the retention time of 4.2min. The drug was eluting at the retention time of 5.4min. In the case of sodium lauryl sulphate, two prominent degradation peaks were observed at the retention time of 3.7 and 13.25min along with few very low-intensity degradation peaks. CONCLUSION: The drug showed 41%, 64%, 72% and 98% degradation in presence of polyvinylpyrrolidone, polyethylene glycol 6000, polysorbate 80 and sodium lauryl sulphate, respectively. PMID- 29174609 TI - [Impact of an automated dispensing system for medical devices in cardiac surgery department]. AB - To secure medical devices' management, the implementation of automated dispensing system in surgical service has been realized. The objective of this study was to evaluate security, organizational and economic impact of installing automated dispensing system for medical devices (ASDM). The implementation took place in a cardiac surgery department. Security impact was assessed by comparing traceability rate of implantable medical devices one year before and one year after installation. Questionnaire on nurses' perception and satisfaction completed this survey. Resupplying costs, stocks' evolution and investments for the implementation of ASDM were the subject of cost-benefit study. After one year, traceability rate is excellent (100%). Nursing staffs were satisfied with 87.5% by this new system. The introduction of ASDM allowed a qualitative and quantitative decrease in stocks, with a reduction of 30% for purchased medical devices and 15% for implantable medical devices in deposit-consignment. Cost benefit analysis shows a rapid return on investment. Real stock decrease (purchased medical devices) is equivalent to 46.6% of investment. Implementation of ASDM allows to secure storage and dispensing of medical devices. This system has also an important economic impact and appreciated by users. PMID- 29174610 TI - Toxoplasma and Africa: One Parasite, Two Opposite Population Structures. AB - Exploring the genetic diversity of Toxoplasma gondii is essential for an understanding of its worldwide distribution and the determinants of its evolution. Africa remains one of the least studied areas of the world regarding T. gondii genetic diversity. This review has compiled published data on T. gondii strains from Africa to generate a comprehensive map of their continent-wide geographical distribution. The emerging picture about T. gondii strain distribution in Africa suggests a geographical separation of the parasite populations across the continent. We discuss the potential role of a number of factors in shaping this structure. We finally suggest the next steps towards a better understanding of Toxoplasma epidemiology in Africa in light of the strains circulating on this continent.

PMID- 29174614 TI - Marketing and Testosterone Treatment in the USA: A Systematic Review. AB - CONTEXT: Testosterone replacement therapy (TRT) is currently approved by the Food and Drug Administration only for classic hypogonadism, although off-label indications have resulted in a dramatic expansion in prescriptions in the USA. Marketing may significantly affect prescriber behavior. OBJECTIVE: To systematically review all available evidence on marketing and TRT in the USA. EVIDENCE ACQUISITION: PubMed, Embase, and Scopus were searched up to July 2017 for all relevant publications reporting on assessments of the TRT market size, economic costs associated with hypogonadism, trends in TRT prescriptions, drug discontinuation rates, and advertising and sales efforts in the USA. EVIDENCE SYNTHESIS: Twenty retrospective studies were included in the final analysis. The market size for hypogonadism constitutes 5.6-76.8% of men in the USA, with the lower end of the range representing the strictest criteria for diagnosis. Men with a diagnosis of hypogonadism consume $14 118 in direct and indirect costs to the payer. Over the last 2 decades, TRT prescriptions have increased between 1.8- and 4-fold. After 1 yr, 80-85% of men discontinue TRT. There is an association between direct-to-consumer advertising and testosterone testing, TRT prescriptions, and TRT without testosterone testing. There is a high prevalence of misinformation on Internet advertising. CONCLUSIONS: Off-label indications have driven the dramatic expansion of TRT prescriptions over the last 2 decades. Direct-to-consumer advertising poses a unique challenge in the USA. Overtreatment can be avoided by applying strict diagnostic criteria for hypogonadism, which limits the addressable market for TRT. PATIENT SUMMARY: In this report, we reviewed the relationship between marketing and testosterone therapy in the USA. We found that many patients are prescribed testosterone without an appropriate diagnosis of hypogonadism, which may be related to the marketing efforts for off label prescribing. PMID- 29174615 TI - Can Focal Treatment Replace Radical Treatment in Prostate Cancer? For Focal Therapy. PMID- 29174616 TI - Surgical Treatment of Male Postprostatectomy Incontinence: Current Concepts. AB - CONTEXT: Radical prostatectomy is the most common reason for male stress urinary incontinence. There is still insecurity about its therapeutic management. OBJECTIVE: To evaluate current evidence regarding therapy of postprostatectomy incontinence (PPI). EVIDENCE ACQUISITION: In October 2017, a nonsystematic review of the literature published within the last 2 yr was performed using the PubMed/Medline database. In total, 58 articles were included in the current analysis. EVIDENCE SYNTHESIS: Regarding invasive management of moderate-to-severe PPI, artificial urinary sphincter (AUS) is still the treatment of choice. Recent studies focused on efficacy, but also a plethora of potential predictive features for treatment success has been investigated. Owing to inconsistent results, there still is no consensus about valid risk factors of AUS treatment success to date. There are increasing efficacy data about the use of adjustable slings, and long term follow-up results are now available for the AdVanceXP male sling. Evidence addressing the use of the quadratic Virtue male sling needs further evaluation. To date, there is no randomized controlled trial investigating the outcome of one specific surgical treatment or comparing the outcome of different surgical treatment options. Limitations include the nonsystematic approach. CONCLUSIONS: Level of evidence addressing the surgical management of PPI is increasing but still unsatisfying. PATIENT SUMMARY: In this review article, we look at current research regarding surgical management of stress urinary incontinence following radical prostatectomy. Many studies focus on how to predict treatment failure and outcomes after artificial urinary sphincter implantation. In addition, more information on the long-term results after male sling implantation is now available. PMID- 29174612 TI - Mortality and its determinants in antiretroviral treatment-naive HIV-infected children with suspected tuberculosis: an observational cohort study. AB - BACKGROUND: Tuberculosis is a major cause of morbidity and mortality in HIV infected children, but is difficult to diagnose. We studied mortality and its determinants in antiretroviral treatment (ART)-naive HIV-infected children presenting with suspected tuberculosis. METHODS: In this observational cohort study, HIV-infected children aged 13 years or younger with suspected tuberculosis were followed up for 6 months as part of the ANRS 12229 PAANTHER 01 cohort in eight hospitals in four countries (Burkina Faso, Cambodia, Cameroon, and Vietnam). Children started ART and antituberculosis treatment at the clinician's discretion and were retrospectively classified into one of three groups by tuberculosis documentation: confirmed by culture or Xpert MTB/RIF, unconfirmed, and unlikely. We assessed mortality and associated factors using Kaplan-Meier methods and Cox proportional hazard models. The ANRS 12229 PAANTHER 01 study is registered at ClinicalTrials.gov, number NCT01331811. FINDINGS: 266 (61%) of 438 children enrolled in the study between April 27, 2011, and May 31, 2014, were ART naive and included in the analysis (40 had confirmed tuberculosis, 119 unconfirmed tuberculosis, and 107 unlikely tuberculosis). 112.5 person-years of follow-up were available. 154 children (58%) started antituberculosis treatment and 212 (80%) started ART. 50 children (19%) died. Mortality by 6 months was higher in children with confirmed tuberculosis (14 deaths; 2 month survival probability 65.0% [95% CI 50.2-79.8]) compared with unconfirmed tuberculosis (19 deaths; 83.5% [76.8-90.3]) and unlikely tuberculosis (17 deaths; 83.5% [76.3 90.7]; log-rank p=0.0141) and was lower in children with confirmed or unconfirmed tuberculosis who started antituberculosis treatment (p<0.0001 for both). In a multivariate analysis, ART started during the first month of follow-up (hazard ratio 0.08; 95% CI 0.01-0.67), confirmed tuberculosis (6.33; 2.15-18.64), young age (5.90; 2.02-17.19), CD4 less than 10% (2.63; 1.25-5.53), miliary features (4.08; 1.56-10.66), and elevated serum transaminases (4.40; 1.82-10.65) were all independently associated with mortality. INTERPRETATION: In our cohort, mortality was high in the first 6 months after suspicion of tuberculosis in ART-naive children. ART should be started early, particularly in children with factors associated with high mortality. Documented or empirical tuberculosis treatment decision should be accelerated to reduce mortality and allow early ART initiation. FUNDING: ANRS and Fondation Total.

AB - In vivo reprogramming of reactive glial cells to neurons has opened a new horizon in regenerative medicine. Our previous study showed that astrocytes could be converted to neurons by the microRNA-302/367 (miR-302/367) cluster in adult brains. In this study, we investigated the possible contribution of miR-302/367 induced neurons in behavioral improvement and neural repair in an Alzheimer's disease (AD) animal model. The AD model was induced by an intracerebroventricular (i.c.v) injection of streptozotocin (STZ). GFP-only or miR-302/367+GFP expressing lentiviral particles were injected into the dentate gyrus of the hippocampus along with intraperitoneal (i.p) valproate (VPA) injection, 3weeks after the STZ administration. We assessed short-term and spatial memories by the Y-maze and Morris water maze (MWM) tasks, respectively. Electrophysiological activities of induced neuron-like cells were investigated using a whole-cell patch clamp technique, 6months after injection of miR-302/367. Behavioral analysis showed that the STZ injection significantly impaired short-term memory and increased escape latency parameter in the MWM task. Compared to STZ and STZ+VPA groups, miR 302/367 combined with VPA significantly improved the spontaneous alternation and spatial memory. Immunostaining against NeuN, as a mature neuronal marker, and its quantification indicated that co-labeled GFP and NeuN significantly increased in the miR-302/367+VPA group. Induced neurons were detected 6months after the miR 302/367 injection. The patch-clamp recording suggested that induced neurons could fire repetitive action potential like endogenous neurons. In conclusion, our results indicated that in vivo reprogramming of reactive astrocytes to neurons by the miR-302/367 cluster might be considered as a novel strategy to restore learning and memory in AD patients.

AB - PURPOSE: To compare safety and efficacy of vascular plugs (VPs) and fibered platinum coils (FPCs) for embolization in pelvic congestion syndrome (PCS). MATERIALS AND METHODS: A randomized, prospective, single-center study enrolled 100 women with PCS from January 2014 to January 2015. Patients were randomly assigned to 2 groups, and embolization was performed with FPCs (n = 50) or VPs (n = 50). Mean age of patients was 42.7 years +/- 7.60, and mean visual analog scale (VAS) score for pelvic pain before treatment was 7.4 +/- 7.60. Primary outcome (clinical success at 1 y using a VAS), number of devices, procedure and fluoroscopy times, radiation doses, costs, and complications were compared, and participants were followed at 1, 3, 6, and 12 months. RESULTS: Clinical success and subjective improvement were not significantly different at 1-year follow-up (89.7% for FPCs vs 90.6% for VPs; P = .760). Mean number of devices per case was 18.2 +/- 1.33 for FPCs and 4.1 +/- 0.31 for VPs (P < .001). Three FPCs and 1 VP migrated to pulmonary vasculature approximately 3-6 months after the embolization procedure; all were retrieved without complications. The FPC group had a significantly longer fluoroscopy time (33.4 min +/- 4.68 vs 19.5 min +/- 6.14) and larger radiation dose (air kerma 948.0 mGy +/- 248.45 vs 320.7 mGy +/- 134.33) (all P < .001). CONCLUSIONS: Embolization for PCS resulted in pain relief in 90% of patients; clinical success was not affected by embolic device. VPs were associated with decreased fluoroscopy time and radiation dose. PMID- 29174619 TI - An elemental approach to modelling the mechanics of the cochlea. AB - The motion along the basilar membrane in the cochlea is due to the interaction between the micromechanical behaviour of the organ of Corti and the fluid movement in the scalae. By dividing the length of the cochlea into a finite number of elements and assuming a given radial distribution of the basilar membrane motion for each element, a set of equations can be separately derived for the micromechanics and for the fluid coupling. These equations can then be combined, using matrix methods, to give the fully coupled response. This elemental approach reduces to the classical transmission line model if the micromechanics are assumed to be locally-reacting and the fluid coupling is assumed to be entirely one-dimensional, but is also valid without these assumptions. The elemental model is most easily formulated in the frequency domain, assuming quasi-linear behaviour, but a time domain formulation, using state space method, can readily incorporate local nonlinearities in the micromechanics. Examples of programs are included for the elemental model of a human cochlea that can be readily modified for other species. PMID- 29174620 TI - Numerical study of temperature effects on the poro-viscoelastic behavior of articular cartilage. AB - This paper presents a new approach to study the effects of temperature on the poro- elastic and viscoelastic behavior of articular cartilage. Biphasic solid fluid mixture theory is applied to study the poro-mechanical behavior of articular cartilage in a fully saturated state. The balance of linear momentum, mass, and energy are considered to describe deformation of the solid skeleton, pore fluid pressure, and temperature distribution in the mixture. The mechanical model assumes both linear elastic and viscoelastic isotropic materials, infinitesimal strain theory, and a time-dependent response. The influence of temperature on the mixture behavior is modeled through temperature dependent mass density and volumetric thermal strain. The fluid flow through the porous medium is described by the Darcy's law. The stress-strain relation for time-dependent viscoelastic deformation in the solid skeleton is described using the generalized Maxwell model. A verification example is presented to illustrate accuracy and efficiency of the developed finite element model. The influence of temperature is studied through examining the behavior of articular cartilage for confined and unconfined boundary conditions. Furthermore, articular cartilage under partial loading condition is modeled to investigate the deformation, pore fluid pressure, and temperature dissipation processes. The results suggest significant impacts of temperature on both poro- elastic and viscoelastic behavior of articular cartilage.

PMID- 29174623 TI - Conservatively Managed Peyronie's Disease-Long-term Survey Results From Patients Undergoing Nonsurgical and Noninjection Therapies. AB - OBJECTIVE: To evaluate patient-reported temporal changes in penile curvature, pain, shortening, sexual function, and quality of life in men undergoing conservative treatment for PD. MATERIALS AND METHODS: Of 3840 patients who underwent evaluation at our institution between 1990 and 2012, 719 were randomly selected to receive a mail-in questionnaire with topics including penile curvature, pain, shortening, sexual function, and quality of life. Men endorsing prior intralesional or surgical therapy were excluded. RESULTS: A total of 125 patients completed the survey and met the inclusion criteria. The median duration between onset of PD symptoms and survey completion was 8.4 years. Overall, 38% felt that their condition had overall improved and 26% felt that their condition had worsened since onset. Penile curvature resolved in 43%, remained stable in 37%, and worsened in 20%. Twelve percent of the men developed a second de novo curvature. Penile pain occurred in 42%, among whom the pain worsened in 18% and completely resolved in 64%. Sixty-five percent reported penile shortening. Subjective erectile function decreased in 60%, and >40% experienced difficulties with penetrative intercourse. Sexual frequency decreased in 68% of the patients and 59% reported decreased relationship satisfaction. Approximately 50% described negative psychological impacts on self-esteem and image. CONCLUSION: The current report provides the most comprehensive and longest-term data on patient-reported outcomes in men undergoing nonsurgical and noninjection therapies. Although approximately 40% of the men reported overall and curvature improvement at a median 8.4-year follow-up, penile length loss, worsening sexual function, relationship dissatisfaction, and psychosocial distress occurred in the majority of PD men. PMID- 29174624 TI - Clinical Utility of Routine Follow-up Cystography in the Management of Traumatic Bladder Ruptures. AB - OBJECTIVE: To evaluate if follow-up cystography alters clinical management in patients after treatment of traumatic bladder ruptures. METHODS: Patients with uncomplicated blunt trauma bladder ruptures between 2000 and 2014 were identified in our institutional trauma registry. Primary management strategies consisted of either cystorrhaphy or catheter drainage. Primary outcome analyzed was occurrence of positive follow-up cystogram. Secondary outcomes were use of follow-up cystography and time to negative cystogram. RESULTS: One hundred forty patients were identified with a median follow-up of 6.2 months (interquartile range [IQR] 3.0-32.4). Eighty-two patients (58.6%) had extraperitoneal (EP) ruptures, 49 had intraperitoneal (IP) ruptures (35.0%), and 9 had combined EP/IP rupture (6.4%). Fifty-six EP patients were managed with catheter drainage, whereas all other patients underwent cystorrhaphy. Thirty-five cystorrhaphy patients (42%) had no imaging before catheter removal. Forty-nine patients (58%) had cystograms at a median of 15.0 days (IQR 10.0-22.0) after cystorrhaphy, with only 1 patient having a persistent leak. Forty-six catheter drainage EP patients (82%) had negative cystograms at a median of 19.0 days (IQR 15.0-33.0). Of the 10 patients with persistent extravasation, 7 required operations for related complications, whereas 3 had negative imaging at a median of 38.0 days (IQR 25.8-66.8), with a mean of 2.8 cystograms before a negative study. CONCLUSION: Follow-up cystography after cystorrhaphy for uncomplicated blunt trauma-associated bladder ruptures rarely, if ever, provides unanticipated clinical information. For catheter drainage EP patients, cystography remains clinically valuable, as at least 18% of patients will have signs of continued extravasation. The optimal timing of cystography and catheter removal remains unknown. PMID- 29174625 TI - Congenital Stenosis of the External Orifice of the Urethra in a Female Child. AB - Limited numbers of pediatric stenosis of the external orifice of the urethra have been reported. We report a case of congenital stenosis of the external orifice of the urethra in a female child who underwent meatoplasty. As an initial strategy for congenital stenosis of the external orifice of the urethra in girls, dilatation of the stenosed urethral meatus may be another management of choice. PMID- 29174626 TI - [Impact of interventions in the pressure ulcer rate]. AB - OBJECTIVE: To evaluate the impact of a risk management program for prevention of pressure ulcers (PUs) in an adult Intensive Care Unit (ICU). MATERIAL AND METHODS: A quantitative, prospective study performed with a "before and after" evaluation, and designed in three stages: 1) PU incidence study; 2) Intervention by implementing a risk management program, and 3) Assessment of the impact. RESULTS: Adherence to the preventive measures showed a significant increase (11.7%) between the first month of the program and the final month (58.5%) of the assessment. Initial PU rate was 20.9, with a decrease in the rate to 14.0 per 1000 bed occupancy days (P<.05) after the risk management program. CONCLUSIONS: The data show that the risk management program, using prevention measures, was effective in reducing the rate of PU in the period under study by more than 33%. PMID- 29174627 TI - Role of NMDA receptor GluN2D subunit in the antidepressant effects of enantiomers of ketamine. AB - We investigated the rapid and sustained antidepressant effects of enantiomers of ketamine in N-methyl-d-aspartate (NMDA) receptor GluN2D subunit knockout (GluN2D KO) mice. Intraperitoneal administration of ketamine or its enantiomers 10 min before the tail-suspension test exerted significant antidepressant effects on restraint stress-induced depression in both wildtype and GluN2D-KO mice. The antidepressant effects of (RS)-ketamine and (S)-ketamine were sustained 96 h after the injection in both wildtype and GluN2D-KO mice, but such sustained antidepressant effects of (R)-ketamine were only observed in wildtype mice. These data suggest that the GluN2D subunit is critical for the sustained antidepressant effects of (R)-ketamine.

AB - Recently RNA sequencing revealed high mucin 13 (MUC13) expression in hepatocellular carcinoma (HCC) tissues. To understand the clinicopathologic significance of MUC13 in HCC, quantitative PCR and immunohistochemistry were used to detect its expression in paired tumor tissues and nontumor tissues. The oncoprotein role of MUC13 was determined by in vitro and in vivo assays. Overexpression of MUC13 was detected in 74 of 168 primary HCC cases (44%) and was significantly associated with tumor size (P = 0.027), stage (P = 0.006), encapsulation (P = 0.044), venous invasion (P = 0.024), and poor outcome (P = 0.004). Functional studies demonstrated MUC13 had strong oncogenic activity by promoting cell growth, colony formation, cell migration, and tumor formation in nude mice. The pro-oncogenic effect of MUC13 were effectively inhibited by RNA interference. MUC13 promoted cellular G1/S phase transition by activating Wnt signaling. Mechanistically, MUC13 bound to beta-catenin and increased its phosphorylation at Ser552 and Ser675 sites, which subsequently promoted nuclear translocation of beta-catenin and up-regulation of its downstream target genes Axin2, c-Myc, and CyclinD1. Knockdown of AKT with shRNA in MUC13-overexpressing cells nullified the elevated phosphorylation of beta-catenin by MUC13. In clinical HCC samples, nuclear translocation of beta-catenin was significantly associated with MUC13 overexpression (P = 0.001). Overexpression of MUC13 plays a critical role in the development and progression of HCC by activating Wnt signaling. PMID- 29174629 TI - Effect of transformational leadership on job satisfaction and patient safety outcomes. AB - BACKGROUND: Improving patient safety within health care organizations requires effective leadership at all levels. PURPOSE: The objective of this study was to investigate the effects of nurse managers' transformational leadership behaviors on job satisfaction and patient safety outcomes. METHODS: A random sample of acute care nurses in Ontario (N = 378) completed the crosssectional survey. Hypothesized model was tested using structural equation modeling. FINDING: The model fit the data acceptably. Transformational leadership had a strong positive influence on workplace empowerment, which in turn increased nurses' job satisfaction and decreased the frequency of adverse patient outcomes. Subsequently, job satisfaction was related to lower adverse events. CONCLUSION: The findings provide support for managers' use of transformational leadership behaviors as a useful strategy in creating workplace conditions that promote better safety outcomes for patients and nurses. PMID- 29174630 TI - Is the adjustable transobturator system ATOMS(r) useful for the treatment of male urinary incontinence in low to medium volume urological centers? AB - INTRODUCTION: Urinary incontinence (UI) is a complication of radical prostatectomy (RP) and transurethral resection of the prostate (TURP). The gold standard treatment is the artificial urinary sphincter, however, new treatments have been investigated. OBJECTIVE: To examine the outcome of an adjustable transobturator male system (ATOMS(r)) in men with UI after prostatic surgery in a low to medium volume continence center. MATERIALS AND METHODS: Twenty-five men with UI were implanted with ATOMS(r) system between 2012 and 2014. The most common indication was UI after RP (92%), followed by UI after TURP (8%). Eleven patients (44%) had received adjuvant external beam radiotherapy (RT). Patients were considered to be 'dry' if they stopped wearing pads or needed just one protective pad per day; and improved if the daily number of pads used decreased by at least half. The Incontinence Quality of Life questionnaire (ICIQ-SF) was used, adding a verbal question about the satisfaction of the patient considering the outcome. RESULTS: After a mean follow-up of 21.56 months, 64% were dry and 8% revealed a significant improvement. The success of the procedure was negatively correlated with the severity of the previous UI and with previous treatment with RT. Concerning patients satisfaction, 84% of the patients would repeat the procedure. CONCLUSION: ATOMS(r) offers good rates of cure and improvement of UI after prostatic surgery with a reasonable rate of minor complications. The results of this study, performed in a low to medium volume continence center, are comparable to the results achieved in high volume continence centers.

PMID- 29174632 TI - Recent cancer treatment and memory decline in older adults: An analysis of the 2002-2012 Health and Retirement Study. AB - OBJECTIVE: Few studies have examined the impact of cancer treatment on cognitive trajectories in the growing population of older adults diagnosed with and surviving cancer. This study examined whether recent cancer and its treatment accelerated memory decline in older adults. MATERIALS AND METHODS: We conducted a secondary analysis of observations drawn from the Health and Retirement Study (2002-2012), a population-based sample of older adults in the United States. Changes in immediate (IWR) and delayed word recall (DWR) scores were estimated by latent growth modeling in individuals who never had cancer (n=10,939) or had been diagnosed with cancer between 2000 and 2002 and received treatment with some combination of radiation and/or surgery (n=240), chemotherapy only (n=34), or chemotherapy and some combination of radiation and/or surgery (n=64). RESULTS: In the period immediately following treatment, individuals reporting a recent cancer treated with chemotherapy and surgery/radiation experienced significantly more rapid decline in IWR (b =-0.34, SE =0.17, p=0.047) and DWR (b=-0.38, SE=0.19, p=0.049) than the non-cancer group. Sensitivity analyses addressing mortality selection and memory-related disease at baseline attenuated the strength of these associations. There were no other statistically significant differences in estimated linear or quadratic slope by cancer status or treatment. CONCLUSION: Our results support a potential association between recent cancer treatment and trajectories of memory decline in older adults and provide guidance on the interpretation of statistical estimates from panel studies of health and aging. PMID- 29174633 TI - Regulation of innate immune functions by guanylate-binding proteins. AB - Guanylate-binding proteins (GBP) are a family of dynamin-related large GTPases which are expressed in response to interferons and other pro-inflammatory cytokines. GBPs mediate a broad spectrum of innate immune functions against intracellular pathogens ranging from viruses to bacteria and protozoa. Several binding partners for individual GBPs have been identified and several different mechanisms of action have been proposed depending on the organisms, the cell type and the pathogen used. Many of these anti-pathogenic functions of GBPs involve the recruitment to and the subsequent destruction of pathogen containing vacuolar compartments, the assembly of large oligomeric innate immune complexes such as the inflammasome, or the induction of autophagy. Furthermore, GBPs often cooperate with immunity-related GTPases (IRGs), another family of dynamin-related GTPases, to exert their anti-pathogenic function, but since most IRGs have been lost in the evolution of higher primates, the anti-pathogenic function of human GBPs seems to be IRG-independent. GBPs and IRGs share biochemical and structural properties with the other members of the dynamin superfamily such as low nucleotide affinity and a high intrinsic GTPase activity which can be further enhanced by oligomerisation. Furthermore, GBPs and IRGs can interact with lipid membranes. In the case of three human and murine GBP isoforms this interaction is mediated by C-terminal isoprenylation. Based on cell biological studies, and in analogy to the function of other dynamins in membrane scission events, it has been postulated that both GBPs and IRGs might actively disrupt the outer membrane of pathogen-containing vacuole leading to the detection and destruction of the pathogen by the cytosolic innate immune system of the host. Recent evidence, however, indicates that GBPs might rather function by mediating membrane tethering events similar to the dynamin-related atlastin and mitofusin proteins, which mediate fusion of the ER and mitochondria, respectively. The aim of this review is to highlight the current knowledge on the function of GBPs in innate immunity and to combine it with the recent progress in the biochemical characterisation of this protein family.

AB - Using a nonparametric Bayesian approach Palacios and Minin (2013) dramatically improved the accuracy, precision of Bayesian inference of population size trajectories from gene genealogies. These authors proposed an extension of a Gaussian Process (GP) nonparametric inferential method for the intensity function of non-homogeneous Poisson processes. They found that not only the statistical properties of the estimators were improved with their method, but also, that key aspects of the demographic histories were recovered. The authors' work represents the first Bayesian nonparametric solution to this inferential problem because they specify a convenient prior belief without a particular functional form on the population trajectory. Their approach works so well and provides such a profound understanding of the biological process, that the question arises as to how truly "biology-free" their approach really is. Using well-known concepts of stochastic population dynamics, here I demonstrate that in fact, Palacios and Minin's GP model can be cast as a parametric population growth model with density dependence and environmental stochasticity. Making this link between population genetics and stochastic population dynamics modeling provides novel insights into eliciting biologically meaningful priors for the trajectory of the effective population size. The results presented here also bring novel understanding of GP as models for the evolution of a trait. Thus, the ecological principles foundation of Palacios and Minin (2013)'s prior adds to the conceptual and scientific value of these authors' inferential approach. I conclude this note by listing a series of insights brought about by this connection with Ecology. PMID- 29174635 TI - The independent loss model with ordered insertions for the evolution of CRISPR spacers. AB - Today, the CRISPR (clustered regularly interspaced short palindromic repeats) region within bacterial and archaeal genomes is known to encode an adaptive immune system. We rely on previous results on the evolution of the CRISPR arrays, which led to the ordered independent loss model, introduced by Kupczok and Bollback (2013). When focusing on the spacers (between the repeats), new elements enter a CRISPR array at rate theta at the leader end of the array, while all spacers present are lost at rate rho along the phylogeny relating the sample. Within this model, we compute the distribution of distances of spacers which are present in all arrays in a sample of size n. We use these results to estimate the loss rate rho from spacer array data for n=2 and n=3.

AB - Neuronal loss is a prominent phenomenon in Alzheimer's disease (AD) and alcohol induced brain damage. Alcohol abuse is associated with an increased risk of AD, regardless of the type of alcoholic beverage. Furthermore, the detrimental effect of excessive alcohol consumption on the risk of AD is exacerbated among people carrying apolipoprotein E (APOE) epsilon4 allele, the major genetic risk factor for AD. However, how APOE epsilon4 and alcohol abuse synergistically enhance the possibility of AD is unclear. Here we show that in N2a cells stably expressing human APP695 (N2a-APP), high-concentration ethanol-induced neurotoxicity was significantly augmented in the presence of apoE4 protein, compared with apoE3 protein. Early and late apoptotic cells were apparently more in cells treated with the combination of apoE4 and ethanol, compared with that of apoE3 and ethanol. Inhibition of apoptosis using a pan-caspase inhibitor z-vad resulted in abolishment of the apoE isoform-specific effect on high-concentration ethanol induced neurotoxicity. Moreover, compared with apoE3, apoE4 augmented ethanol induced cellular oxidative stress, and pre-incubation with a reactive oxygen species (ROS) scavenger NAC abrogated the specific effect of apoE4 on ethanol induced neurotoxicity. Taken together, our results for the first time demonstrate that apoE4 and high-concentration ethanol synergistically enhance neurotoxicity through elevating cellular oxidative stress and increasing neuronal apoptosis, and support the notion that avoiding excessive alcohol consumption can help to prevent AD especially in APOE epsilon4 carriers. PMID- 29174638 TI - Upregulation of CCL7 and CCL2 in reward system mediated through dopamine D1 receptor signaling underlies methamphetamine-induced place preference in mice. AB - We previously showed that the CC-chemokine ligand 2 (CCL2)-CC-chemokine receptor 2 (CCR2) system is responsible for conditioned place preference (CPP) by methamphetamine (Meth). In this study, we investigated the roles for other chemokines mediating Meth-induced CPP and the upstream factors upregulating chemokines in mice. We found that CCL7 mRNA level was upregulated in the prefrontal cortex (PFC) after Meth administration (3mg/kg, subcutaneous), and increased CCL7 immunoreactivity was localized to the PFC NeuN-positive neurons. Meth-induced CPP was blocked by the dopamine D1 receptor antagonist SCH 23390 but not by the D2 receptor antagonists raclopride or haloperidol. The D1 receptor agonist SKF 81297 alone elicited CPP, suggesting a critical role of D1 receptor signaling in Meth-induced reward. Consistent with these results, the Meth-induced upregulation of CCL7 and CCL2 were attenuated by SCH 23390, and a single administration of SKF 81297 upregulated mRNA expression levels of CCL7 and CCL2 in the PFC. Furthermore, Meth-induced CPP was prevented by INCB 3284, a selective antagonist of CCR2, a receptor that binds both CCL7 and CCL2. Collectively, we identified two CC-chemokines (i.e., CCL7 and CCL2) as key regulatory factors in Meth-induced reward. Pharmacological inhibitors of these chemokines may warrant development as novel therapeutics for ameliorating Meth addiction. PMID- 29174639 TI - Callosotomy affects performance IQ: A meta-analysis of individual participant data. AB - Morphometric neuroimaging studies on healthy adult individuals regularly report a positive association between intelligence test performance (IQ) and structural properties of the corpus callosum (CC). At the same time, studies examining the effect of callosotomy on epilepsy patients report only negligible changes in IQ as result of the surgery, partially contradicting the findings of the morphometry studies. Objective of the present meta-analysis of individual participant data (IPD) of 87 cases from 16 reports was to re-investigate the effect of callosotomy on full scale IQ as well as on the verbal and performance subscale under special consideration of two possible moderating factors: pre-surgical IQ levels and the extent of the surgery (complete vs. anterior transsection). The main finding was that callosotomy selectively affects performance IQ, whereby the effect is modulated by the pre-surgical level of performance. Patients with an above-median pre-surgery performance IQ level show a significant average decrease of -5.44 (CI95%: - 8.33 to - 2.56) IQ points following the surgery, while the below-median group does not reveal a significant change in IQ (mean change: 1.01 IQ points; CI95%: -1.83 to 3.86). Thus, the present analyses support the notion that callosotomy has a negative effect on the patients' performance IQ, but only in those patients, who at least have an average performance levels before the surgery. This observation also lends support to the findings of previous morphometry studies, indicating that the frequently observed CC-IQ correlation might indeed reflect a functional contribution of callosal interhemispheric connectivity to intelligence-test performance. PMID- 29174640 TI - Dorsal raphe nucleus glucocorticoid receptors inhibit tph2 gene expression in male C57BL/6J mice. AB - The serotonergic dorsal raphe nucleus (DRN) expresses glucocorticoid receptors (GR), and systemic glucocorticoids have been shown to regulate expression and activity of tryptophan hydroxylase isoform 2, the rate-limiting enzyme for serotonin synthesis in brain. We have used intra-DRN injection of pseudotyped adeno-associated virus AAV2/9 transducing either green fluorescent protein (GFP control) or Cre recombinase (DRN GR deletion) in floxed GR mice to determine if DRN GR directly regulate DRN mRNA levels of tryptophan hydroxylase 2 (tph2). In a separate set of similarly-treated floxed GR mice, we also measured limbic forebrain region concentrations of serotonin (5-hydroxytryptamine; 5-HT) and its major metabolite, 5-hydroxyindoleacetic acid (5-HIAA). DRN GR deletion increased tph2 mRNA levels in the dorsal, lateral wing, and caudal parts of the DRN without altering tissue concentrations of 5-HT, 5-HIAA, or the 5-HIAA/5-HT ratio in limbic forebrain regions. We conclude that DRN GR inhibit DRN tph2 gene expression in mice without marked effects on serotonin metabolism, at least under basal conditions at the circadian nadir. These data provide the first evidence of localized control of DRN tph2 mRNA expression by DRN GR in mice.

By integrating emission source data with existing official statistics as well as using rescaling methodology of data mapping for 1 km grid, the authors constructed high resolution emission gridded data in Beijing-Tianjin-Hebei (Jing-Jin-Ji) region in China for 2012. Comparisons between urban and non-urban areas of carbon emissions from industry, agriculture, household and transport exhibited regional disparities as well as sectoral differences. Except for the Hebei province, per capita total direct carbon emissions from urban extents in Beijing and Tianjin were both lower than provincial averages, indicating the climate benefit of urbanization, comparable to results from developed countries. Urban extents in the Hebei province were mainly industrial centers while those in Beijing and Tianjin were more service oriented. Further decomposition analysis revealed population to be a common major driver for increased carbon emissions but climate implications of urban design, economic productivity of land use, and carbon intensity of GDP were both cluster- and sector-specific. This study disapproves the one-size-fits-all solution for carbon mitigation but calls for down-scaled analysis of carbon emissions and formulation of localized carbon reduction strategies in the Jing-Jin-Ji as well as other regions in China.

AB - Alcohol (ethanol) and methamphetamine (METH) co-abuse is a major public health issue. Ethanol or METH exposure has been associated with changes in neurotransmitter levels in several central brain regions. However, little is known about the effect of sequential exposure to ethanol and METH on glutamate, dopamine and serotonin tissue content in striatum and hippocampus. In this study, we investigated the effects of sequential exposure to ethanol and METH on tissue content of these neurotransmitters. Male Wistar rats were orally gavaged with either ethanol (6g/kg) or water for seven days. Rats were administered with high dose of METH (10mg/kg, i.p. every 2h*4) or saline on Day 8 and euthanized 48h of last METH or saline i.p. injection. In the striatum, sequential exposure to ethanol and METH increased glutamate tissue content while reducing dopamine and serotonin tissue content as compared to the group exposed to ethanol alone. In the hippocampus, sequential exposure to ethanol and METH decreased serotonin tissue content as compared to the group that was exposed to ethanol alone. However, this study showed that ethanol has no additive effect to METH on tissue content of dopamine and serotonin as compared to METH in the striatum and hippocampus. This study demonstrated that sequential exposure of ethanol and METH has an additive effect on tissue content of certain neurotransmitters in the brain.

AB - The inactivation of Bacillus anthracis spores on subway and used subway railcar materials was evaluated using fogged peracetic acid/hydrogen peroxide (PAA) and hydrogen peroxide (H2O2). A total of 21 separate decontamination tests were conducted using bacterial spores of both B. anthracis Ames (B.a.) and Bacillus atrophaeus (B.g.) inoculated onto several types of materials. Tests were conducted using commercial off-the-shelf fogging equipment filled with either PAA or H2O2 to fumigate a ~15 cubic meter chamber under uncontrolled ambient relative humidity and controlled temperature (10 or 20 degrees C) from 8 to 168 h. For the present study, no conditions were found that resulted in complete inactivation of either B.a. Ames or B.g. on all test materials. Approximately 41% and 38% of the decontamination efficacies for B.a. and B.g., respectively, exhibited >=6 log10 reduction (LR); efficacy depended greatly on the material. When testing at 10 degrees C, the mean LR was consistently lower for both B.a. and B.g. as compared to 20 degrees C. Based on the statistical comparison of the LR results, B.g. exhibited equivalent or greater resistance than B.a. for approximately 92% of the time across all 21 tests. The efficacy data suggest that B.g. may be a suitable surrogate for B.a. Ames when assessing the decontamination efficacy of fogged PAA or H2O2. Moreover, the results of this testing indicate that in the event of B.a. spore release into a subway system, the fogging of PAA or H2O2 represents a decontamination option for consideration. PMID- 29174644 TI - Does the reduction of inferior turbinate affect lower airway functions? AB - INTRODUCTION: Although the nose and lungs are separate organs, numerous studies have reported that the entire respiratory system can be considered as a single anatomical and functional unit. The upper and lower airways affect each other either directly or through reflex mechanisms. OBJECTIVE: In this study, we aimed to evaluate the effects of the radiofrequency ablation of persistent inferior turbinate hypertrophy on nasal and pulmonary function. METHODS: Twenty-seven patients with bilateral persistent inferior turbinate hypertrophy without septal deviation were included in this study. All of the patients were evaluated using anterior rhinoscopy, nasal endoscopy, acoustic rhinometry, a visual analogue scale, and flow-sensitive spirometry on the day before and 4 months after the radiofrequency ablation procedure. RESULTS: The post-ablation measurements revealed that the inferior turbinate ablation caused an increase in the mean cross-sectional area and volume of the nose, as well as in the forced expiratory volume in 1s, forced vital capacity, and peak expiratory flow of the patients. These differences between the pre- and post-ablation results were statistically significant. The post-ablation visual analogue scale scores were lower when compared with the pre-ablation scores, and this difference was also statistically significant. CONCLUSION: This study demonstrated that the widening of the nasal passage after the reduction of the inferior turbinate size had a favorable effect on the pulmonary function tests.

AB - This research was planned to identify the attitudes of emergency department nurses towards patient safety. The study was performed as descriptive. The universe of the research the universe comprised hospitals defined as 3rd level according to Turkish health care classification, which provides service to all health disciplines in Istanbul. The sample consisted of emergency department (ED) nurses who work in those hospitals. The data was collected by using tools such as the "Information Questionnaire" and the "Patient Safety Attitudes Scale". In this study, the attitudes of ED nurses towards patient safety were found to be average and was not related to age, gender, education level, nursing experience, ED experience, ED certification, patient safety training, nurse's self sufficiency perception of patient safety, hospital's quality certification or ED quality certification. The attitudes of nurses towards patient safety were compared by age, gender, marital status, education level, ED experience and there was no meaningful difference. However, a meaningful difference was found between the age groups and the "defining stress" sub-dimension of the Patient Safety Attitudes Scale. ED nurses' status of certification for emergency care, patient safety training, training of quality, hospitals' or ED's quality certification status had no significant statistical difference.

AB - Previous theoretical studies have indicated that liquid bridges close to the Plateau-Rayleigh instability limit can be stabilized when the upper supporting disk vibrates at a very high frequency and with a very small amplitude. The major effect of the vibration-induced pressure field is to straighten the liquid bridge free surface to compensate for the deformation caused by gravity. As a consequence, the apparent Bond number decreases and the maximum liquid bridge length increases. In this paper, we show experimentally that this procedure can be used to stabilize millimeter liquid bridges in air under normal gravity conditions. The breakup of vibrated liquid bridges is examined experimentally and compared with that produced in absence of vibration. In addition, we analyze numerically the dynamics of axisymmetric liquid bridges far from the Plateau Rayleigh instability limit by solving the Navier-Stokes equations. We calculate the eigenfrequencies characterizing the linear oscillation modes of vibrated liquid bridges, and determine their stability limits. The breakup process of a vibrated liquid bridge at that stability limit is simulated too. We find qualitative agreement between the numerical predictions for both the stability limits and the breakup process and their experimental counterparts. Finally, we show the applicability of our technique to control the amount of liquid transferred between two solid surfaces.

AB - In this study, a novel three-dimensional zinc-based metal-organic framework (Zn MOF), i.e., {Zn2(L)2(DMF)2H2O}n (L = 2,5-bis(phenylamino)-1,4-benzenedicarboxylic acid) was designed and developed under solvothermal condition. As a proof-of principle, a pi-conjugated framework of carboxylate ligand capable of "bottom up" synthesis was integrated with metal ion to construct a novel MOF for sensing applications. As expected, the synthesized Zn-MOF exhibited fluorescence enhancement for cadmium ion (Cd2+) and sensing of nitrobenzene (NB) through fluorescence quenching. The detection limits were calculated to be 0.12 MUM for Cd2+ and 1.19 MUg mL-1 for NB based on signal-to-noise ratio of 3:1. Moreover, various techniques and density functional theory investigations verified that the possible sensing mechanisms for Cd2+ and NB included ion exchange and photoinduced electron transfer, respectively. Finally, their practical applications on real samples also demonstrated that the Zn-MOF-based sensor can be effectively utilized for detection and imaging of Cd2+ present in the real water samples and living cells. This study may inspire future research and design of target fluorescent MOFs with specific functions.

AB - Acid extracting aluminum from fly ash would produce pestilent secondary fly ash slurry with strong acidity, high content of Cl- and residual Al3+ that is difficult to be further used. In order to achieve the zero emission, a potential integrated treatment process for reutilization was proposed in this paper. By intelligent use of residual Al3+ in sludge as catalyst, hydrophobic modification of solid particle was taken with fatty acid via a heterogeneous esterification at normal temperature. Due to the solvophobic force, moisture content of its filter cake was 36.46%, which reduced 11.14% compared with the unmodified one, hydrophobicity scale can achieve 100% with modifier accounting for only 0.8% of solid content and the Cl- concentrations decreased from 20 to 0.102 g/L in wash liquor, thus greatly saving water for washing and energy for drying. Subsequently, based on the appearance of hydrocarbon chains on particle surface, a high-efficiency ultraviolet-induced grafting polymerization was implemented to fabricate density polyacrylic acid decorated fly ash particles from the surface "CH" sites, the resultant composite was proved to efficiently separate valuable rare-earth Gd3+ from wastewater with outstanding adsorption and regeneration performance, hence bringing high added-value utilization for these hazardous waste. PMID- 29174651 TI - Cancer combination therapy of the sesquiterpenoid artesunate and the selective EGFR-tyrosine kinase inhibitor erlotinib. AB - BACKGROUND: The shift from cytotoxic to targeted chemotherapy led to improved treatment outcomes in oncology. Nevertheless, many cancer patients cannot be cured from their disease because of the development of drug resistance and side effects. PURPOSE: There is an ongoing quest for novel compounds, which raised not only the interest in natural products but also in novel combination therapy regimens. STUDY DESIGN: In this review, we report on the inhibition epidermal growth factor receptor (EGFR) by targeted small molecules and their combination with natural products from medicinal plants. RESULTS: The combination of erlotinib with artesunate leads to synergistic inhibition of cell growth in isobologram analyses. Artesunate is an approved anti-malaria drug, which is also active against cancer as shown in vitro, in vivo and in preliminary clinical phase I/II trials. CONCLUSION: The combination of natural products (e.g. the sesquiterpenoid artesunate) and synthetic compounds (e.g. the small molecule EGFR tyrosine kinase inhibitor erlotinib) may lead to improved clinical success rates in oncology. PMID- 29174650 TI - Orphan neuropeptides and receptors: Novel therapeutic targets. AB - Neuropeptides are the largest class of intercellular signaling molecules, contributing to a wide variety of physiological processes. Neuropeptide receptors are therapeutic targets for a broad range of drugs, including medications to treat pain, addiction, sleep disorders, and nausea. In addition to >100 peptides with known functions, many peptides have been identified in mammalian brain for which the cognate receptors have not been identified. Similarly, dozens of "orphan" G protein-coupled receptors have been identified in the mammalian genome. While it would seem straightforward to match the orphan peptides and receptors, this is not always easily accomplished. In this review we focus on peptides named PEN and big LEN, which are among the most abundant neuropeptides in mouse brain, and their recently identified receptors: GPR83 and GPR171. These receptors are co-expressed in some brain regions and are able to interact. Because PEN and big LEN are produced from the same precursor protein and co secreted, the interaction of GPR83 and GPR171 is physiologically relevant. In addition to interactions of these two peptides/receptors, PEN and LEN are co localized with neuropeptide Y and Agouti-related peptide in neurons that regulate feeding. In this review, using these peptide receptors as an example, we highlight the multiple modes of regulation of receptors and present the emerging view that neuropeptides function combinatorially to generate a network of signaling messages. The complexity of neuropeptides, receptors, and their signaling pathways is important to consider both in the initial deorphanization of peptides and receptors, and in the subsequent development of therapeutic applications. PMID- 29174652 TI - Introduction: Novel hybrid combinations containing synthetic or antibiotic drugs with plant-derived phenolic or terpenoid compounds. AB - BACKGROUND: There is a paradigm shift in chemotherapy from mono-drug therapy towards multidrug combination regimens. Natural products from medicinal plants may play an important role for the design of novel combination therapy protocols. HYPOTHESIS: We introduce the novel term "hybrid combination" for the therapeutic combination of chemically defined plant-derived constituents (e.g. phenolic or terpenoid compounds with synthetic or antibiotic drugs to increase pharmacological activity and simultaneously toxic side effects. STUDY DESIGN: Several literature databases were screened on the combination of phenolic/terpenoid compounds with synthetic/antibiotic drugs. RESULTS: Phenolic compounds are water soluble and interact with target proteins due to their OH groups. They reveal antioxident, antiinflammatory and sometimes apoptotic activities whereas the terpenoids possess due to their lipophilic nature together with the phenolics amphiphilic properties and thereby good cell-penetrating features. They reveal antioxidant properties, anti-inflammatory and sometimes apoptotic activities as well as cell-penetrating features due to their amphiphilicity. Synergistic or antagonistic interactions with synthetic or antibiotic drugs have to be demonstrated by using suitable methods (e.g. isobologram analysis). The molecular modes of action may be elucidated by approaches of network pharmacology (e.g. protein-protein interaction networks). CONCLUSION: There is convincing evidence for the improvement of pharmacological activity at reduced side effects by hybrid combinations. Future efforts should focus on clinical trials with hybrid combinations to treat a broad range of diverse diseases such as cardiometabolic and neurotropic syndromes, drug resistance phenotypes, and so-called neglected infectious diseases. PMID- 29174653 TI - Color-coded LED microscopy for quantitative phase imaging: Implementation and application to sperm motility analysis. AB - Color-coded light-emitting diode (LED) microscopy (cLEDscope) is a novel computational microscopy technique capable of multi-contrast and quantitative phase imaging of biological specimens using color-multiplexed illumination. Using specially designed LED patterns, it is capable of recording multiple differential phase contrast (DPC) images in a single exposure and employs a computational algorithm to retrieve the phase distribution of the specimens. Herein, we describe the detailed procedures in the cLEDscope implementation for quantitative phase imaging. Several notable features and caveats in the cLEDscope setup and image processing are also outlined. The imaging model is derived for our specific configuration, and the associated phase-retrieval algorithms are presented on the basis of a weak-object transfer function. As an illustrative application of the quantitative cLEDscope, we demonstrate its utility as a sperm-motility analyzer by exploiting its real-time quantitative imaging capability.

AB - Touchscreens are a potential source of pathogen transmission. In our facility, patients and visitors rarely perform hand hygiene after using interactive touchscreen computer kiosks. An automated ultraviolet-C touchscreen disinfection device was effective in reducing bacteriophage MS2, bacteriophage phiX174, methicillin-resistant Staphylococcus aureus, and Clostridium difficile spores inoculated onto a touchscreen. In simulations, an automated ultraviolet-C touchscreen disinfection device alone or in combination with hand hygiene reduced transfer of the viruses from contaminated touchscreens to fingertips.

PMID- 29174657 TI - Serious unintended outcomes associated with cesarean section. AB - BACKGROUND: Serious unintended outcomes (SUOs) associated with cesarean section (CS), defined in this study as sepsis, endometritis, or wound disruption, occurring during the admission to deliver an infant by CS, or on readmission for wound disruption, are not routinely measured in a manner that continuously evaluates their impact on women's health. METHODS: The Texas Healthcare Information Collection Public Use Data File was used to investigate trends in the diagnosis of SUOs over a 5-year period from January 1, 2010-December 31, 2014. RESULTS: CS-associated SUOs affected 9.24 women for every 1,000 CSs. During the study period, a large decrease in the rate of SUOs occurred (R2 = 0.60). This was potentially influenced by a large decrease in the rate of endometritis (R2 = 0.41). Decreases in the diagnosis of and readmission for CS wound disruption were not as large (R2 = 0.06 and R2 = 0.03, respectively). A large increase in CS associated sepsis (R2 = .32) was identified. Administrative coded data used to identify SUOs in this study may have utility for the identification of serious unintended outcomes associated with CS at the population level. CONCLUSIONS: Increases in length of stay and utilization of critical care were noted among women affected by CS-associated SUOs. Additional study is needed to determine factors that increase the likelihood of the development of SUO and to evaluate the preventability of these events.

PMID- 29174659 TI - Impact of a Monoplane Hemodynamic TEE (hTEE) Monitoring Device on Decision Making in a Heterogeneous Hemodynamically Unstable Intensive Care Unit Population: A Prospective, Observational Study. AB - OBJECTIVE: This prospective observational study was undertaken to evaluate the utility of a miniature transesophageal echocardiography probe (ImaCor hemodynamic [hTEE]) in the management of hemodynamically unstable intensive care unit patients with and without various forms of mechanical circulatory support. DESIGN: A prospective observational study. SETTING: A single tertiary care cardiothoracic and surgical intensive care unit. PARTICIPANTS: Fifty-three cardiothoracic and surgical intensive care unit patients undergoing miniature transesophageal echocardiography examinations. All patients had hemodynamic instability as defined by necessity of mechanical circulatory support (MCS) devices or vasoactive medications. INTERVENTIONS: From April 2012 to February 2014, 53 hemodynamically unstable intensive care unit patients received an examination with the miniature transesophageal echocardiography probe when deemed necessary by the intensivist for rapid and/or ongoing transesophageal echocardiographic examinations. Twenty-eight of the examinations were performed in patients with MCS devices (53%). The remainder of examinations (n = 25, 47%) were performed in patients after other cardiothoracic surgery or noncardiac surgery with cardiac complications. MEASUREMENTS AND MAIN RESULTS: The measured endpoint was determination of usefulness of management guidance due to the miniature transesophageal echocardiographic examination as assessed by the intensivist caring for the patient. The incidence of hTEE imaging provoking a change in management also was recorded. Overall, of the 53 examinations, 77% (n = 41) provided useful information to the management. Of the 25 examinations in patients without MCS, 92% (n = 23) of the examinations were useful in guiding management. Among the 28 examinations in patients with MCS devices, 64% (n = 18) of examinations were useful in guiding management (odds ratio = 0.156; 95% confidence interval, 0.015-0.899; p = 0.022). Eight of the 53 examinations (15%) were deemed to have "poor image quality" by the echocardiographer. Age, sex, and body mass index did not significantly affect the usefulness of the hTEE examinations. CONCLUSION: Examination of a heterogeneous hemodynamically unstable intensive care population with a miniature transesophageal echocardiography probe provided useful information beyond standard intensive care unit monitoring data, which influenced post-hTEE medical decision making. The examinations were more useful in patients without MCS devices than in those with MCS. Of the patients with MCS, patients with durable ventricular assist devices had the lowest rate of useful examinations.

PMID- 29174662 TI - Keep Ventilating the Lungs While the Heart is Still Ejecting on Femoro-femoral Cardiopulmonary Bypass. AB - Femoro-femoral cardiopulmonary bypass (CPB) followed by deep hypothermic circulatory arrest is one of the modalities used for ascending aortic pseudoaneurysm repair to achieve cardiac unloading and to avoid severe hemorrhage due to the risk of rupture during the sternal entry. However, due to the limited size of the cannulas, it can be challenging to achieve total cardiopulmonary support. Therefore, despite the achievement of total cardiopulmonary support, the heart may still be able to eject antegrade blood flow that meets the retrograde blood flow from the arterial side of the CPB. The point where the blood flow meets in the aorta is called the watershed area. If the antegrade blood flow is large due to a left ventricular ejection, the watershed area will be located in the descending aorta. Therefore, if ventilation is stopped, deoxygenated blood will be ejected to the cerebral circulation. Cerebral near-infrared spectroscopy (NIRS) may be used as a noninvasive and continuous measurement of regional brain oxygen saturation (rSO2). This case demonstrates that cerebral desaturation due to discontinued mechanical ventilation, when the heart was still ejecting during the initial phase of femoro-femoral CPB, immediately was detected by a pronounced drop bilaterally: In the left frontal lobe, rSO2 fell from 56% to 21%, and in the right frontal lobe it fell from 47% to 25%. The authors recommend monitoring cerebral saturation using NIRS in the case of femoro-femoral CPB.

AB - OBJECTIVES: To prevent infective endocarditis in patients with predisposing cardiac conditions, antibiotic prophylaxis is recommended worldwide, except in the United Kingdom. To determine the relevance of this strategy, investigating how the current guidelines are applied is crucial. The first aim of this study was to assess dentists' implementation of the current guidelines. The secondary aims were to identify relevant areas to improve the training of dentists and to determine temporal trends in practitioners' attitudes by comparison with 2 previous surveys conducted in 1991 and 2001. STUDY DESIGN: An electronic national survey was sent to the 12,000 member practitioners of the French Union for Oral Health. RESULTS: Even though 58.9% of the respondents stated that their knowledge of current guidelines was good, a scoring system showed that only 34.5% had overall knowledge of these guidelines. CONCLUSIONS: This study revealed relevant areas to improve the training of dentists, such as knowledge of some cardiac conditions, the potential side effects of the antibiotics used, and the pathogenesis of infective endocarditis. Consequently, dentists' knowledge should be improved before any conclusions can be drawn on the relevance of this antibiotic prophylaxis strategy and its influence on infective endocarditis incidence. PMID- 29174664 TI - Measuring E-cigarette dependence: Initial guidance. AB - E-cigarette use rates are increasing among youth and adults, despite limited knowledge about the safety, risks, and potential for this product in substituting for or reducing other tobacco use. Understanding how to characterize and assess e cigarette dependence will be important for evaluating the public health impact of e-cigarettes and considering prevention and intervention strategies. To provide an initial review of constructs to consider when assessing e-cigarette dependence, a content expert group within the Tobacco Center for Regulatory Science (TCORS) Measurement Workgroup engaged in a review of published manuscripts and 12 tobacco dependence measures, followed by review of suggested dependence domains by a 10-person external subject-matter expert panel. The final domains selected to be considered in the development of a measure of e-cigarette dependence included: 1) Quantity and frequency of use, 2) Tolerance, 3) Perceived benefits, 4) Withdrawal symptoms, 5) Craving/urge to use, 6) Use despite harm, 7) Impaired control, 8) Automaticity, 9) Preferred over competing rewards, and 10) Sensory dependence. Similarities and differences in potential features of e cigarette dependence compared with dependence on other tobacco products is discussed. Future work will evaluate these dependence items and constructs in a sample of e-cigarette users with a goal of developing a valid, brief, standardized measure of e-cigarette dependence. PMID- 29174665 TI - Pro-tobacco advertisement exposure among African American smokers: An ecological momentary assessment study. AB - INTRODUCTION: Many African Americans live in communities with a disproportionately high density of tobacco advertisements compared to Whites. Some research indicates that point-of-sale advertising is associated with impulse purchases of cigarettes and smoking. Ecological Momentary Assessment (EMA) can be used to examine associations between tobacco advertisement exposure and smoking variables in the natural environment. METHODS: Non-treatment seeking African American smokers were given a mobile device for 2weeks (N=56). They were prompted four times per day and responded to questions about recent exposure to tobacco advertisements. Participants were also asked to indicate the number of cigarettes smoked, and if they made any purchase, or an impulse purchase, since the last assessment. Linear mixed models (LMMs) analyzed between- and within-subject associations between exposure and outcomes. RESULTS: Participants reported seeing at least one advertisement on 33% of assessments. Of those assessments, they reported seeing menthol advertisements on 87% of assessments. Between-subject analyses revealed that participants who on average saw more advertisements were generally more likely to report purchasing cigarettes and to purchase cigarettes on impulse. Within-subject analyses revealed that when an individual participant reported seeing more advertisements than usual they were more likely to have reported purchasing cigarettes, making an impulse purchase and smoking more cigarettes during the same period, but not the subsequent time period. CONCLUSIONS: Many African American smokers are frequently exposed to pro-tobacco marketing. Advertisement exposure is cross-sectionally associated with impulse purchases and smoking. Future research should assess prospective associations in more detail. PMID- 29174667 TI - Metal-organic gel enhanced fluorescence anisotropy for sensitive detection of prostate specific antigen. AB - In this contribution, we demonstrated that Cu-based metal-organic gel (Cu-MOG) was able to serve as a novel amplification platform for fluorescence anisotropy (FA) assay for the first time, which was confirmed by the sensitive detection of a common cancer biomarker, prostate specific antigen (PSA). The dye-labeled probe aptamer (PA) product was adsorbed onto the benzimidazole derivative-containing Cu MOG via electrostatic incorporation and strong pi-pi stacking interactions, which significantly increased the FA value due to the enlargement of the molecular volume of the PA/Cu-MOG complex. With the introduction of target PSA, the FA value was obviously decreased on account of the specific recognition between PSA and PA which resulted in the detachment of PA from the surface of MOG. The linear range was from 0.5-8ng/mL, with a detection limit of 0.33ng/mL. Our work has thus helped to demonstrate promising application of MOG material in the fields of biomolecules analysis and disease diagnosis.

AB - Polarized Raman spectra for 11 modes in the YVO4 crystal were measured in the temperature range from room temperature to 473K, and the mode assignment on Raman modes was analyzed using the first-principles calculations. We found that the calculated frequency values are in good agreement with the experimental ones. The large difference of the temperature line broadening between two peaks (380cm-1 and 891cm-1) of A1g mode has been reported and it is thought to be due to band gap effect in PDOS. PMID- 29174666 TI - Combining ecological momentary assessment with objective, ambulatory measures of behavior and physiology in substance-use research. AB - Whereas substance-use researchers have long combined self-report with objective measures of behavior and physiology inside the laboratory, developments in mobile/wearable electronic technology are increasingly allowing for the collection of both subjective and objective information in participants' daily lives. For self-report, ecological momentary assessment (EMA), as implemented on contemporary smartphones or personal digital assistants, can provide researchers with near-real-time information on participants' behavior and mood in their natural environments. Data from portable/wearable electronic sensors measuring participants' internal and external environments can be combined with EMA (e.g., by timestamps recorded on questionnaires) to provide objective information useful in determining the momentary context of behavior and mood and/or validating participants' self-reports. Here, we review three objective ambulatory monitoring techniques that have been combined with EMA, with a focus on detecting drug use and/or measuring the behavioral or physiological correlates of mental events (i.e., emotions, cognitions): (1) collection and processing of biological samples in the field to measure drug use or participants' physiological activity (e.g., hypothalamic-pituitary-adrenal axis activity); (2) global positioning system (GPS) location information to link environmental characteristics (disorder/disadvantage, retail drug outlets) to drug use and affect; (3) ambulatory electronic physiological monitoring (e.g., electrocardiography) to detect drug use and mental events, as advances in machine learning algorithms make it possible to distinguish target changes from confounds (e.g., physical activity). Finally, we consider several other mobile/wearable technologies that hold promise to be combined with EMA, as well as potential challenges faced by researchers working with multiple mobile/wearable technologies simultaneously in the field. PMID- 29174669 TI - Application of terahertz spectroscopy and theoretical calculation in dimethylurea isomers investigation. AB - The characteristic absorption spectra of two structural isomers of dimethylurea(DMU) in 0.6-1.8 THz region have been measured using terahertz time domain spectroscopy (THZ-TDS) at room temperature. Significant differences have been found between their terahertz spectra and implied that the THZ-TDS is an effective means of identifying structural isomers. To simulate their spectra, calculations on single molecule and cluster of 1,1-DMU and 1,3-DMU were performed, and we found that the cluster calculations using DFT-D3 method are better to predict the experimental spectra. Using the normal mode as displacements in redundant internal coordinates and the GaussView program, most observed THz vibrational modes are assigned to bending and rocking modes related to the intermolecular hydrogen bonding interactions, and twisting mode of ethyl groups. The different spectral features of two isomers mainly arise from different intermolecular hydrogen bonds resulting from different atom arrangements in molecules and different molecule arrangements in crystals. Using the reduced-density-gradient (RDG) analysis, the positions and types of intermolecular hydrogen bonding interactions in 1,1-DMU and 1,3-DMU crystals are visualized. Therefore, we can confirm that THz-TDS can be used as an effective means for the recognition of structural isomers and detection of intermolecular hydrogen bonding interactions in these crystals.

PMID- 29174672 TI - [Aluminic intoxication in chronic hemodialysis. A diagnosis rarely evoked nowadays. Clinical case and review of the literature]. AB - Aluminum intoxication in chronic hemodialysis patients has virtually vanished over the last decade. Therefore, the diagnosis is rarely advocated at present. Aluminum intoxication in dialysis patients associates to different degrees with dialysis encephalopathy, bone disorders and microcytic anemia. We report here the observation of a patient receiving intermittent hemodialysis therapy who presented with acute encephalopathy. It turned out to be caused by aluminum intoxication secondary to a defect in dialysis water treatment. Whatever the therapeutic approach, the prognosis of this dramatic complication in hemodialysis patients remains poor. In severe cases, only renal transplantation can be able to improve clinical outcome. Major sources of aluminum are tap water used for dialysis together with a defective water treatment system, and to a minor extent oral aluminum-containing phosphate binders and antacids. In the absence of a bone biopsy, the diagnosis can be made by measuring serum aluminum or better after a desferrioxamine test. Prevention of aluminum overload is of utmost importance. It is the responsibility of dialysis centers to provide aluminum-free water and dialysis fluid. In case of proven aluminum intoxication, the K/DOQI guidelines indicated how to best treat hemodialysis patients, based on long-term desferrioxamine infusions during the hemodialysis session. It is recommended to implement a stepwise increasing desferrioxamine dosage to prevent an acute decompensation with irreversible neurological lesions.

AB - The controlled patterning of polymeric surfaces at the micro- and nanoscale offers potential in the technological development of small-scale devices, particularly within the fields of photovoltaics, micro-optics and lab- and organ on-chip, where the topological arrangement of the surface can influence a system's power generation, optical properties or biological function - such as, in the latter case, biomimicking surfaces or topological control of cellular differentiation. One of the most promising approaches in reducing manufacturing costs and complexity is by exploitation of the self-assembling properties of colloidal particles. Self-assembly techniques can be used to produce colloidal crystals onto surfaces, which can act as replicative masks, as has previously been demonstrated with colloidal lithography, or templates in mold-replication methods with resolutions dependent on particle size. Within this context, a particular emerging interest is focused on the use of self-assembled colloidal crystal surfaces in polymer replication methods such as soft lithography, hot and soft embossing and nano-imprint lithography, offering low-cost and high resolution alternatives to conventional lithographic techniques. However, there are still challenges to overcome for this surface patterning approach to reach a manufacturing reliability and process robustness comparable to competitive technologies already available in the market, as self-assembly processes are not always 100% effective in organizing colloids within a structural pattern onto the surface. Defects often occur during template fabrication. Furthermore, issues often arise mainly at the interface between colloidal crystals and other surfaces and substrates. Particularly when utilized in high-temperature pattern replication processes, poor adhesion of colloidal particles onto the substrate results in degradation of the patterning template. These effects can render difficulties in creating stable structures with little defect that are well controlled such that a large variety of shapes can be reproduced reliably. This review presents an overview of available self-assembly methods for the creation of colloidal crystals, organized by the type of forces governing the self assembly process: fluidic, physical, external fields, and chemical. The main focus lies on the use of spherical particles, which are favorable due to their high commercial availability and ease of synthesis. However, also shape anisotropic particle self-assembly will be introduced, since it has recently been gaining research momentum, offering a greater flexibility in terms of patterning. Finally, an overview is provided of recent research on the fabrication of polymer nano- and microstructures by making use of colloidal self-assembled templates.

AB - BACKGROUND: Insulin-like growth factor I (IGF-I) is a key regulator of chondrogenesis, but its therapeutic application to articular cartilage damage is limited by rapid elimination from the repair site. The human IGF-I gene gives rise to three IGF-I propeptides (proIGF-IA, proIGF-IB and proIGF-IC) that are cleaved to create mature IGF-I. In this study, we elucidate the processing of IGF I precursors by articular chondrocytes, and test the hypotheses that proIGF-I isoforms bind to heparin and regulate articular chondrocyte biosynthesis. METHODS: Human IGF-I propeptides and mutants were overexpressed in bovine articular chondrocytes. IGF-I products were characterized by ELISA, western blot and FPLC using a heparin column. The biosynthetic activity of IGF-I products on articular chondrocytes was assayed for DNA and glycosaminoglycan that the cells produced. RESULTS: Secreted IGF-I propeptides stimulated articular chondrocyte biosynthetic activity to the same degree as mature IGF-I. Of the three IGF-I propeptides, only one, proIGF-IA, strongly bound to heparin. Interestingly, heparin binding of proIGF-IA depended on N-glycosylation at Asn92 in the EA peptide. To our knowledge, this is the first demonstration that N-glycosylation determines the binding of a heparin-binding protein to heparin. CONCLUSION: The biosynthetic and heparin binding abilities of proIGF-IA, coupled with its generation of IGF-I, suggest that proIGF-IA may have therapeutic value for articular cartilage repair. GENERAL SIGNIFICANCE: These data identify human pro insulin-like growth factor IA as a bifunctional protein. Its combined ability to bind heparin and augment chondrocyte biosynthesis makes it a promising therapeutic agent for cartilage damage due to trauma and osteoarthritis.

AB - BACKGROUND: India is responsible for 30% of the annual global cohort of unvaccinated children worldwide. Private practitioners provide an estimated 21% of vaccinations in urban centers of India, and are important partners in achieving high vaccination coverage. METHODS: We used an in-person questionnaire and on-site observation to assess knowledge, attitudes, and practices of private immunization service providers regarding delivery of immunization services in the urban settings of Surat and Baroda, in Gujarat, India. We constructed a comprehensive sampling frame of all private physician providers of immunization services in Surat and Baroda cities, by consulting vaccine distributors, local branches of physician associations, and published lists of private medical practitioners. All providers were contacted and asked to participate in the study if they provided immunization services. Data were collected using an in-person structured questionnaire and directly observing practices; one provider in each practice setting was interviewed. RESULTS: The response rate was 82% (121/147) in Surat, and 91% (137/151) in Baroda. Of 258 participants 195 (76%) were pediatricians, and 63 (24%) were general practitioners. Practices that were potential missed opportunities for vaccination (MOV) included not strictly following vaccination schedules if there were concerns about ability to pay (45% of practitioners), and not administering more than two injections in the same visit (60%). Only 22% of respondents used a vaccination register to record vaccine doses, and 31% reported vaccine doses administered to the government. Of 237 randomly selected vaccine vials, 18% had expired vaccine vial monitors. CONCLUSIONS: Quality of immunization services in Gujarat can be strengthened by providing training and support to private immunization service providers to reduce MOVs and improve quality and safety; other more context specific strategies that should be evaluated may involve giving feedback to providers on quality of services delivered and working through professional societies to adopt standards of practice.

AB - A beta-1,3-d-glucan called Schizophyllan (SPG) can form a novel complex with homo oligodeoxynucleotides (ODNs) via the combination of hydrogen bonding and hydrophobic interactions. Dectin-1 is a major receptor involved in the recognition of beta-1,3-d-glucans and expressed on antigen presenting cells (APCs) including macrophages, dendritic cells, monocytes, neutrophils, and a subset of T cells. Therefore, the SPG/ODN complex can be used as APCs cell specific delivery of functional ODNs including unmethylated CpG sequences (CpG ODNs). In fact, CpG-ODN/SPG complex induced high antibody titers when it was administered to cynomolgus monkeys as adjutant of influenza vaccine. These results indicate that SPG can be an excellent immunocyte-targeting drug delivery system. PMID- 29174676 TI - Leaf saponins of Quillaja brasiliensis enhance long-term specific immune responses and promote dose-sparing effect in BVDV experimental vaccines. AB - Saponin-based adjuvants are promising adjuvants that enhance both humoral and T cell-mediated immunity. One of the most used natural products as vaccine adjuvants are Quillaja saponaria bark saponins and its fraction named Quil A(r). Despite that, its use has been restricted for human use due to safety issues. As an alternative, our group has been studying the congener species Quillaja brasiliensis saponins and its performance as vaccine adjuvants, which have shown to trigger humoral and cellular immune responses comparable to Quil A(r) but with milder side effects. Here, we studied a semi purified aqueous extract (AE) and a previously little characterized saponin-enriched fraction (QB-80) from Q. brasiliensis as vaccine adjuvants and an inactivated virus (bovine viral diarrhea virus, BVDV) antigen co-formulated in experimental vaccines in mice model. For the first time, we show the spectra pattern of the Q. brasiliensis saponins by MALDI-TOF, a novel and cost-effective method that could be used to characterize different batches during saponins production. Both AE and QB-80 exhibited noteworthy chemical similarities to Quil A(r). In addition, the haemolytic activity and toxicity were assessed, showing that both AE and QB-80 were less toxic than Quil A(r). When subcutaneously inoculated in mice, both fractions promoted long-term strong antibody responses encompassing specific IgG1 and IgG2a, enhanced the avidity of IgG antibodies, induced a robust DTH reaction and significantly increased IFN-gamma production in T CD4+ and T CD8+ cells. Furthermore, we have proven herein that AE has the potential to promote dose sparing, substantially reducing the dose of antigen required for the BVDV vaccines and still eliciting a mixed Th1/Th2 strong immune response. Based on these results, and considering that AE is a raw extract, easier and cheaper to produce than commercially available saponins, this product can be considered as candidate to be escalated from experimental to industrial uses. PMID- 29174677 TI - In vivo electroporation enhances vaccine-mediated therapeutic control of human papilloma virus-associated tumors by the activation of multifunctional and effector memory CD8+ T cells. AB - In vivo electroporation (EP) has reignited the clinical interest on DNA vaccines as immunotherapeutic approaches to control different types of cancer. EP has been associated with increased immune response potency, but its capacity in influencing immunomodulation remains unclear. Here we evaluated the impact of in vivo EP on the induction of cellular immune responses and therapeutic effects of a DNA vaccine targeting human papillomavirus-induced tumors. Our results demonstrate that association of EP with the conventional intramuscular administration route promoted a more efficient activation of multifunctional and effector memory CD8+ T cells with enhanced cytotoxic activity. Furthermore, EP increased tumor infiltration of CD8+ T cells and avoided tumor recurrences. Finally, our results demonstrated that EP promotes local migration of antigen presenting cells that enhances with vaccine co-delivery. Altogether the present evidences shed further light on the in vivo electroporation action and its impact on the immunogenicity of DNA vaccines.

The mouse neutralization test is the only pharmacopeia assay to measure the potency of antitoxin preparations. Herein, we present an in vitro cell-based assay for the measurement of pharmaceutical type A antitoxin potency. Accuracy, reproducibility and compatibility with the mouse bioassay were demonstrated using different batches of standard antitoxin and toxin preparations. The established assay may substantially reduce the use of laboratory animals in the process of pharmaceutical antitoxin production. PMID- 29174679 TI - Molecular epidemiology of influenza B virus and implications in immunization strategy, Southern Brazil. AB - Epidemiological indicators have shown the substantial impact of influenza B (Flu B) on the development of severe acute respiratory infection (SARI) and on mortality rates. In Brazil, the trivalent vaccine, composed of only one Flu B lineage is available. We investigated Flu B infections in clinical samples collected by the epidemiological surveillance service of Parana State, Brazil, from 2013 to 2016. The Flu B lineages Yamagata- (B/Yam) and Victoria-like (B/Vic) were identified using the qRT-PCR assay, and notification forms were reviewed. Among 379 Flu B positive samples evaluated, 370 (98%) were characterized as B/Yam or B/Vic lineages. Both co-circulated with a frequency of 47% and 53%, respectively. B/Yam infected equally both genders, while B/Vic was more frequent in females (71%). The median age of patients infected by B/Vic (23y; 11-35) was lower than that of patients infected by B/Yam (32y; 12-50). Mismatch between the vaccine and the circulating strain was observed in the 2013 season, with a high number of SARI cases. B/Vic lineage was associated with a larger number of SARI cases (62%), while B/Yam with influenza-like illness (ILI) (61%). Differences were observed in the strains circulating in separate regions of Parana State. B/Vic was prevalent in the northwestern (67%) and B/Yam in the southeastern region (60%). The unpredictability of Flu B lineage circulation causes a substantial increase in severe disease during epidemics in a vaccine mismatch season. In addition, the differences in the epidemiological profile of the target population of Flu B infections in relation to other respiratory viruses, as well as among the B/Vic and B/Yam lineages may also be associated to an increase in disease burden. These findings have direct consequences on vaccination strategies. Therefore, further molecular epidemiology studies of Flu B in Brazil are required to corroborate these primary results. PMID- 29174680 TI - Impact of measles supplementary immunization activities on reaching children missed by routine programs. AB - BACKGROUND: Measles supplementary immunization activities (SIAs) are vaccination campaigns that supplement routine vaccination programs with a recommended second dose opportunity to children of different ages regardless of their previous history of measles vaccination. They are conducted every 2-4 years and over a few weeks in many low- and middle-income countries. While SIAs have high vaccination coverage, it is unclear whether they reach the children who miss their routine measles vaccine dose. Determining who is reached by SIAs is vital to understanding their effectiveness, as well as measure progress towards measles control. METHODS: We examined SIAs in low- and middle-income countries from 2000 to 2014 using data from the Demographic and Health Surveys. Conditional on a child's routine measles vaccination status, we examined whether children participated in the most recent measles SIA. RESULTS: The average proportion of zero-dose children (no previous routine measles vaccination defined as no vaccination date before the SIA) reached by SIAs across 14 countries was 66%, ranging from 28% in Sao Tome and Principe to 91% in Nigeria. However, when also including all children with routine measles vaccination data, this proportion decreased to 12% and to 58% when imputing data for children with vaccination reported by the mother and vaccination marks on the vaccination card across countries. Overall, the proportions of zero-dose children reached by SIAs declined with increasing household wealth. CONCLUSIONS: Some countries appeared to reach a higher proportion of zero-dose children using SIAs than others, with proportions reached varying according to the definition of measles vaccination (e.g., vaccination dates on the vaccination card, vaccination marks on the vaccination card, and/or self-reported data). This suggests that some countries could improve their targeting of SIAs to children who miss other measles vaccine opportunities. Across all countries, SIAs played an important role in reaching children from poor households. PMID- 29174681 TI - Parental perceptions, attitudes and acceptance of childhood immunization in Saudi Arabia: A cross sectional study. AB - OBJECTIVES: The widespread availability and use of vaccines have tremendously reduced morbidity, mortality and health care costs associated with infectious diseases. However, parental beliefs about vaccination are one of the major factors in achieving high vaccination rates. Thus, this study aims to assess the perceptions and attitudes regarding routine childhood immunization among Saudi parents. METHODS: A cross sectional study with a pre-tested 18-item questionnaire was conducted using 467 randomly selected parents from the Hail region of Saudi Arabia in the period between February 1st, 2016, and February 1st, 2017. The validated questionnaire consisted of three sections that collected information on participants' demographics, parents' awareness of vaccine benefits, and parents' practices regarding the immunization of their children. RESULTS: Female and male parents comprised 54.5% (255) and 45.5% (212) of the sample, respectively, and the response and completion rates were 97%. The majority of the respondents had received a formal education (94.1%, 439), were gainfully employed (62.9%, 294) and had a regular monthly income (73.3%). The majority of the respondents were aware of childhood vaccinations (78.9%), completed vaccinations mandated for children up to 5 years (86.2%), encouraged other parents to do so (89.9%), and had easy access to vaccines (90.5%). Sixty to ninety percent of the respondents were knowledgeable regarding the health benefits of vaccinations in children, even though 18.4% of their children had experienced vaccination-related minor adverse effects during or after vaccination of which 23.2% required doctor's visits. Health care professionals were the most frequent source of parents' vaccine-related information (65.2%), and vaccination reminder services provided by the Ministry of Health (MOH) via mobile phones were cited by 57.5% of respondents. CONCLUSIONS: Confidence in and acceptance of childhood vaccinations, perceptions of vaccine-related health benefits and ease of access to immunizations appeared to be quite good among Saudi parents. PMID- 29174682 TI - Herpes zoster vaccine live: A 10 year review of post-marketing safety experience. AB - BACKGROUND: Zoster vaccine is a single dose live, attenuated vaccine (ZVL) indicated for individuals >=50 years-old for the prevention of herpes zoster (HZ). Safety data from clinical trials and post-licensure studies provided reassurance that ZVL is generally safe and well tolerated. The objective of this review was to provide worldwide post-marketing safety information following 10 years of use and >34 million doses distributed. METHODS: All post-marketing adverse experience (AE) reports received worldwide between 02-May-2006 and 01-May 2016 from healthcare professionals following vaccination with ZVL and submitted to the MSD AE global safety database, were analyzed. RESULTS: A total of 23,556 AE reports, 93% non-serious, were reported. Local injection site reactions (ISRs), with a median time-to-onset of 2 days, were the most frequently reported AEs followed by HZ. The majority of HZ reports were reported within 2 weeks of vaccination and considered, based on time-to-onset, pathogenesis of HZ, and data from clinical trials, to be caused by wild-type varicella-zoster virus (VZV). HZ confirmed by PCR analysis to be VZV Oka/Merck vaccine-strain was identified in an immunocompetent individual 8 months postvaccination and in 4 immunocompromised individuals. Disseminated HZ was reported very rarely (<1%) with 38% occurring in immunocompromised individuals. All reports of disseminated HZ confirmed by PCR as VZV Oka/Merck vaccine-strain were in individuals with immunosuppressive conditions and/or therapy at the time of vaccination. CONCLUSIONS: The safety profile of ZVL, following 10 years of post-marketing use, was favorable and consistent with that observed in clinical trials and post-licensure studies. PMID- 29174684 TI - Food wasters: Profiling consumers' attitude to waste food in Italy. AB - Scientific literature suggests that in developed countries food is predominantly wasted at the consumption stage of the food supply chain. This study aims to profile consumers' attitude to waste food in Italy investigating households' behaviours leading to food waste generation by addressing what is being wasted and why it is wasted. The work is based on a survey performed in Italy on a heterogeneous sample of 3,087 respondents. A cluster analysis was performed to detect consumers' profiles. Results, based on self-reporting, allow to sketch different 'waster' types, providing a picture of food waste related to eating, shopping, and storage behaviours and suggesting a number of differences existing in terms of perceived quantities and causes of generated food waste. Out of seven profiles identified, four are the most representative ones in terms of size: the conscious-fussy type, who wastes because food doesn't smell or look good; the conscious-forgetful type, who forgets what is in the fridge or on the shelves; the frugal consumer who tends not to consume fruits and vegetables and declares to waste nothing (or almost nothing); and the exaggerated cook, who overbuys and overcooks. Profiling specific waste types can help to better understand if groups with common characteristics exist, what their specific features are and what levers can be employed to stimulate a change in their behaviour. PMID- 29174683 TI - Immunogenicity, reactogenicity and safety of 2 doses of an adjuvanted herpes zoster subunit vaccine administered 2, 6 or 12 months apart in older adults: Results of a phase III, randomized, open-label, multicenter study. AB - BACKGROUND: In phase III trials, 2 doses of a herpes zoster (HZ) subunit vaccine (HZ/su; 50 ug varicella-zoster virus glycoprotein E [gE] and AS01B Adjuvant System) administered 2-months apart in older adults (>=50 and >=70 years) demonstrated >90% efficacy in preventing HZ and had a clinically acceptable safety profile. Here we report immunogenicity, reactogenicity and safety following administration of 2 HZ/su doses at intervals longer than 2 months. METHODS: In this Phase III, open-label trial conducted in the US and Estonia, 354 adults >=50 years were randomized 1:1:1 to receive 2 HZ/su doses 2, 6, or 12 months apart. gE-specific humoral immune responses were evaluated at pre vaccination, 1 and 12 months post-dose 2. Co-primary objectives were to compare immune responses to HZ/su 1 month post-dose 2 when given 6-months or 12-months apart to those administered 2-months apart. For each participant, safety information was collected from dose 1 to 12 months post-dose 2. RESULTS: 346 participants completed the study and 343 were included in the according-to protocol cohort for immunogenicity. One month post-dose 2, vaccine response rates were 96.5% (97.5% confidence interval [CI]: 90.4; 99.2) and 94.5% (97.5% CI: 87.6; 98.3) for the 0, 6- and 0, 12-month schedules, respectively, both schedules meeting the pre-defined criterion. Non-inferiority of anti-gE geometric mean concentrations was demonstrated for HZ/su administered on 0, 6-month compared to a 0, 2-month schedule; however, HZ/su administered on a 0, 12-month schedule did not meet the non-inferiority criterion. Injection site pain was the most commonly reported solicited adverse event (AE). 26 participants each reported at least 1 serious AE; none were assessed as related to vaccination. CONCLUSIONS: Immune responses to HZ/su administered at 0, 6-month were non-inferior to those elicited by a 0, 2-month schedule. HZ/su exhibited a clinically acceptable safety profile for all dosing intervals. CLINICAL TRIALS REGISTRATION: Clinicaltrials.gov (NCT01751165).

AB - This paper analyses time (30 and 60 min) and temperature (120-190 degrees C) effects of intermediate thermal hydrolysis (ITHP) in a two-step anaerobic digestion of waste activated sludge (WAS) with and without wheat straw as a co substrate. Effects were analyzed by measuring biochemical methane potential for 60 days and assessing associated kinetic and chemical data. Compared to non treatment, ITHP increased the secondary step methane yield from 52 to 222 L CH4 kg VS-1 and from 147 to 224 L CH4 kg VS-1 for pre-digested WAS and pre-co digested WAS respectively at an optimum of 170 degrees C and 30 min. The hydrolysis coefficients (khyd) increased by up to 127% following treatment. Increasing ITHP time from 30 to 60 min showed ambiguous results regarding methane yields, whilst temperature had a clear and proportional effect on the concentrations of acetic acid. The energy balances were found to be poor and dewatering to increase total solids above the values tested here is necessary for this process to be energetically feasible. PMID- 29174686 TI - Theory and practice of corrosion related to ashes and deposits in a WtE boiler. AB - Corrosion of heat-exchanging components is one of the main operational problems in Waste-to-Energy plants, limiting the electrical efficiency that can be reached. Corrosion is mainly related to the devolatilization and/or formation of chlorides, sulphates and mixtures thereof on the heat-exchanging surfaces. Theoretical considerations on this corrosion were already put forward in literature, but this paper now for the first time combines theory with a large scale sampling campaign of several Waste-to-Energy plants. Based on the outcome of elemental and mineralogical analysis, the distribution of Cl and S in ashes sampled throughout the plant during normal operation is explained. Cl concentrations are high (15-20%) in the first empty pass, decrease in the second and third empty pass, but increase again in the convective part, whereas the S concentrations show an inverse behavior, with the highest concentrations (30%) observed in the second and third empty pass. Sampling of deposits on specific places where corrosion possibly occurred, gives a better insight in the mechanisms related to corrosion phenomena in real-scale WtE plants and provides practical evidence for some phenomena that were only assumed on the basis of theory or lab scale experiments before. More specific, it confirms the role of oxygen content, temperatures in the different stages of the boiler, the presence of polysulphates, Pb and Zb, and the concentrations of HCl and SO2 in the flue gas for different types of boiler corrosion. PMID- 29174687 TI - Membrane-anchored stalk domain of influenza HA enhanced immune responses in mice. AB - Current strategies for influenza virus vaccines primarily aim to elicit immune responses towards the globular head domain of the hemagglutinin (HA) protein so that binding of the virus to membrane receptors on the host cells is inhibited. In the present study, we show a novel strategy to generate immunity against the highly conserved region of the influenza virus. The globular head domain was replaced by different linkers to generate a headless HA (stalk domain) and then coexpressed with influenza M1 proteinin Tni insect cells. The expression was validated by western blot analysis, and stalk domain with peptides (GGGGS)4 linkers was identified to anchor in a stable way to the cell membrane. An immunoelectron microscope showed that stalk domain with (GGGGS)4 linkers were steadily incorporated to the surface of influenza virus-like particles (VLPs). Mice immunized with these VLPs exhibited enhanced systemic antibody responses with increased binding avidity and study found high titers of ADCC antibodies to the influenza virus, these VLPs also induced mucosal immune responses and produced antigen-specific IgG and IgA in nasal and lung washes. In addition, antigen-specific IgG antibody-secreting cells (ASCs) increased significantly in the spleen and lymph node. The results of this study suggest that the headless HA is a useful target in developing a universal vaccine against influenza virus. PMID- 29174688 TI - Comparative transcriptome analysis reveals induction of apoptosis in chicken kidney cells associated with the virulence of nephropathogenic infectious bronchitis virus. AB - Avian infectious bronchitis virus (IBV) that causes respiratory and nephritic diseases in chicken is a major poultry pathogen leading to serious economic loss worldwide. The nephropathogenic IBV strains cause nephritis and kidney lesions intrinsically and the pathogenic mechanism is still unclear. In the present study, SPF chicks were infected with three nephropathogenic IBVs of different virulence and their gene expression profiles in chicken kidney were compared at transcriptome level. As a result, 1279 differentially expressed (DE) genes were found in very virulent SCDY2 inoculated group, 145 in virulent SCK2 group and 74 in non-virulent LDT3-A group when compared to mock infected group. Gene Ontology (GO) and KEGG pathway enrichment analysis on SCDY2 group displayed that the up regulated DE genes were mainly involved in cell apoptosis, and the down-regulated genes were involved in metabolic processes and DNA replication. Protein-Protein Interaction (PPI) analysis showed that DE genes in SCDY2 group formed a network, and the core of the network was composed by cell apoptosis and immune response proteins. The clustering of gene expression profile among the three virus inoculated groups indicated that the majority of up-regulated DE genes on apoptosis in very virulent SCDY2 group were up-regulated more or less in virulent SCK2 group and those down-regulated on innate immune response in SCDY2 group were also down-regulated differently in SCK2 group. In addition, the number of apoptotic cells detected experimentally in kidney tissue were very different among the three virus inoculated groups and were positively accordant with the viral titer, kidney lesions and viral virulence of each group. Taken all together, the present study revealed that virulent nephropathogenic IBV infection modified a number of gene expression and induction of apoptosis in kidney cells may be a major pathogenic determinant for virulent nephropathogenic IBV. PMID- 29174689 TI - Mortality risks from a spectrum of causes associated with wide-ranging exposure to fine particulate matter: A case-crossover study in Beijing, China. AB - BACKGROUND: Exposure to fine particulate matter (<=2.5MUm in aerodynamic diameter; PM2.5) has been shown to be associated with an increased risk of mortality due to cardiovascular, respiratory, and other pulmonary diseases. However, fewer studies have investigated the relationship between ambient PM2.5 and human mortality for a wider range of causes of death, or for more specific causes of death within these broader categories, especially at the high PM2.5 concentrations currently experienced in Chinese megacities. Beijing, China, has a very large population and a wide range of PM2.5 exposures, allowing a prime opportunity to estimate such risks across a broad spectrum of causes, including rarer causes of death. OBJECTIVE: To estimate the relative risk of cause-specific mortality associated with PM2.5 for a spectrum of causes of death, as well as characterize the time course of cause-specific mortality following PM2.5 exposure, in a location where PM2.5 concentrations are representative of common exposures in Chinese megacities. METHODS: We collected daily data on mortality counts of Beijing residents and Beijing weather and air pollution measurements for January 1, 2009 to December 31, 2012. We used a time-stratified case crossover study design to estimate the association between ambient PM2.5 concentrations and risk of death from several broad causes of death and from more refined specific causes within these broader categories. Primary results were estimated for risks the day of and the day following exposure (lag 0-1), but the time pattern of associated risk was also explored up to seven days following exposure. RESULTS: Increased concentrations of PM2.5 were associated with increased risks at lag days 0-1 of all-cause mortality (0.26% increase per 10MUg/m3; 95% confidence interval [CI]: 0.12%-0.39%), non-accidental deaths (0.25%; 95% CI: 0.11%-0.38%), circulatory deaths (0.39%; 95% CI: 0.21%-0.59%), respiratory deaths (0.43%; 95% CI: 0.05%-0.81%), intentional self-harm deaths (1.94%; 95% CI: 0.19%-3.73%) and nervous system deaths (0.9%; 95% CI: -0.2%-2%), although the observed increase was not statistical significant for the final one rarer cause of death. In addition to these five broad death outcomes, risk also increased following PM2.5 exposure at lag days 0-1 for deaths from several specific causes, including most of the specific circulatory causes considered. The largest observed increased risk by far was for one of the rarest causes of death considered, extrapyramidal and movement disorders (2.35%; 95% CI: 0.03% 4.72%). CONCLUSIONS: This study indicates that exposure to PM2.5 in a study location more representative of exposures in developing cities is associated with an increased risk of mortality from broad range of causes of death, including some causes rarely studied previously in association with PM2.5 exposure.

PMID- 29174691 TI - [Comparison of operative and oncologic results between partial nephrectomy and radiofrequency ablation for treatment of renal tumors in patients older than 75]. AB - INTRODUCTION: Elderly patients represent a growing part of our society for who treatment strategy for localized renal tumors has to be chosen knowing iatrogen effects and renal function morbidity. The aim was to analyze oncological and functional results of nephron sparing surgery (PN) versus radiofrequency ablation (RFA). MATERIALS AND METHODS: All patients aged more than 75 treated by partial nephrectomy or radiofrequency ablation between 2007 and 2014 in our centre were included. Patient and tumors data were compared and these criteria were analyzed: survival (overall and without recurrence) and loss of renal function (pre- and postoperative MDRD). RESULTS: In total, 100 patients were included (26 partial nephrectomies, group 1 and 74 radiofrequency ablation, group 2) with a 32-months medium follow-up. Medium age and tumor size were significantly different (respectively, 78 versus 81 years old, P=0.001, 38mm versus 29mm, P=0.003). Perioperative results showed no differences in complications. Transfusion rate and duration of hospital stay were significantly higher in the PN group. Median overall survival were 45 vs. 27 months (P=0.23) for PN and RFA and median recurrence-free survival were 28 vs. 10 months (P=0.34). On a multivariate analysis, operative technique (PN or RFA) were not significantly linked to survival (HR 2.37 [95% CI: 0.66-8.5]), P=0.19. Loss of renal function were 1.5+/ 14mL/min/1.73m2 for PN and 3+/-14mL/min/1.73m2 for RFA (P=0.69). CONCLUSION: Our study showed better perioperative results for RFA than for PN, without significant different survival. Loss of renal function were little and similar. LEVEL OF EVIDENCE: 4.

AB - Moyamoya disease (MMD) is a rare cerebrovascular disease characterized by a progressive stenosis at the terminal portion of the internal carotid artery and an abnormal vascular network at the base of the brain. Although its etiology is still unknown, intrinsic immune reactions such as autoimmune response has been implicated in the pathogenesis of MMD. Recently, the RING finger protein 213 (RNF213) was found to be an important risk gene for MMD, and is predominantly expressed in blood cells and the spleen. Thus, we hypothesized that patients with MMD represent an intrinsic autoimmune status mediated by M2-polarized macrophages, which play an important role in tissue remodeling and angiogenesis. We compared the serum level of soluble (s)CD163, an activating marker for CD163+ M2-polarized macrophages that has been implicated in a variety of autoimmune disorders, between MMD patients and healthy controls. We also analyzed serum levels of CXCL5, an augmented cytokines that has been correlated with the severity of autoimmune diseases. As a result, the serum sCD163 levels of MMD patients (281,465 pg/ml) were significantly higher than those of healthy controls (174,842 pg/ml) (p = .004). The serum CXCL5 levels of MMD patients (679.02 pg/ml) were significantly higher than those of healthy controls (401.79 pg/ml) (p = .046). There were no differences in the serum sCD163 and CXCL5 levels between each genotype of the RNF213 polymorphism (wild-type or variant) among MMD patients. Although this is a pilot study and further validation with larger number of samples is necessary, our results indicate that patients with MMD may have increased autoimmune activity, and our results shed light on the pathogenesis of MMD via CD163+ M2-polarized macrophages.

AB - Resting-state functional magnetic resonance imaging (fMRI) studies using static functional connectivity (sFC) measures have shown that the brain function is severely disrupted after long-term sleep deprivation (SD). However, increasing evidence has suggested that resting-state functional connectivity (FC) is dynamic and exhibits spontaneous fluctuation on a smaller timescale. The process by which long-term SD can influence dynamic functional connectivity (dFC) remains unclear. In this study, 37 healthy subjects participated in the SD experiment, and they were scanned both during rested wakefulness (RW) and after 36 h of SD. A sliding window based approach and a spectral clustering algorithm were used to evaluate the effects of SD on dFC based on the 26 qualified subjects' data. The outcomes showed that time-averaging FC across specific regions as well as temporal properties of the FC states, such as the dwell time and transition probability, was strongly influenced after SD in contrast to the RW condition. Based on the occurrences of FC states, we further identified some RW-dominant states characterized by anti-correlation between the default mode network (DMN) and other cortices, and some SD-dominant states marked by significantly decreased thalamocortical connectivity. In particular, the temporal features of these FC states were negatively correlated with the correlation coefficients between the DMN and dorsal attention network (dATN) and demonstrated high potential in classification of sleep state (with 10-fold cross-validation accuracy of 88.6% for dwell time and 88.1% for transition probability). Collectively, our results suggested that the temporal properties of the FC states greatly account for changes in the resting-state brain networks following SD, which provides new insights into the impact of SD on the resting-state functional organization in the human brain.

AB - Current study investigated bone morphogenetic protein 12 (BMP12) and connective tissue growth factor (CTGF) activate tendon derived stem cells (TDSCs) tenogenic differentiation, and promotion of injured tendon regeneration. TDSCs were transfected with BMP12 and CTGF via recombinant adenovirus (Ad) infection. Gene transfection efficiency, cell viability and cytotoxicity, tenogenic gene expression, collagen I/III synthesis were evaluated in vitro. For the in vivo study, the transfected cells were transplanted into the rat patellar tendon window defect. At weeks 2 and 8 of post-surgery, the repaired tendon tissues were harvested for histological and biomechanical examinations. The transfected TDSCs revealed relatively stable transfection efficiency (80-90%) with active cell viability means while rare cytotoxicity in each group. During days 1 and 5, BMP12 and CTGF transfection caused tenogenic differentiation genes activation in TDSCs: type I/III collagen, tenascin-C, and scleraxis were all up-regulated, whereas osteogenic, adipogenic, and chondrogenic markers were all down-regulated respectively. In addition, BMP12 and CTGF overexpression significantly promote type I/III collagen synthesis. After in vivo transplantation, at 2 and 8 weeks post-surgery, BMP12, CTGF and co-transfection groups showed more integrated tendon tissue structure versus control, meanwhile, the ultimate failure loads and Young's were all higher than control. Remarkably, at 8 weeks post-surgery, the biomechanical properties of co-transfection group was approaching to normal rat patellar tendon, moreover, the ratio of type III/I collagen maintained about 20% in each transfection group, meanwhile, the type I collagen were significantly increased with co-transfection treatment. In conclusion, BMP12 and CTGF transfection stimulate tenogenic differentiation of TDSCs. The synergistic effects of simultaneous transfection of both may significantly promoted rat patellar tendon window defect regeneration. PMID- 29174695 TI - Use of oral cholera vaccine as a vaccine probe to define the geographical dimensions of person-to-person transmission of cholera. AB - BACKGROUND: Cholera is known to be transmitted from person to person, and inactivated oral cholera vaccines (OCVs) have been shown to confer herd protection via interruption of this transmission. However, the geographic dimensions of chains of person-to-person transmission of cholera are uncertain. The ability of OCVs to confer herd protection was used to define these dimensions in two cholera-endemic settings, one in rural Bangladesh and the other in urban India. METHODS: Two large randomized, placebo-controlled trials of inactivated OCVs, one in rural Matlab, Bangladesh and the other in urban Kolkata, India, were reanalyzed. Vaccine herd protection was evaluated by relating the risk of cholera in placebo recipients to vaccine coverage of surrounding residents residing within concentric rings. In Matlab, concentric rings in 100-m increments up to 700m were evaluated; in Kolkata, 50-m increments up to 350m were evaluated. RESULTS: One hundred and eight cholera cases among 24667 placebo recipients were detected during 1year of post-vaccination follow-up at Matlab; 128 cholera cases among 34968 placebo recipients were detected during 3 years of follow-up in Kolkata. Consistent inverse relationships were observed between vaccine coverage of the ring and the risk of cholera in the central placebo recipient for rings with radii up to 500m in Matlab and up to 150m in Kolkata. CONCLUSIONS: These results suggest that the dimensions of chains of person-to-person transmission in endemic settings can be quite large and may differ substantially from setting to setting. Using OCVs as 'probes' to define these dimensions can inform geographical targeting strategies for the deployment of these vaccines in endemic settings.

PMID- 29174697 TI - Prevalence of Nonmedical Use of Prescription Opioids and Association With Co occurring Substance Use Disorders Among Adolescents in Substance Use Treatment. AB - PURPOSE: We sought to describe the prevalence of the nonmedical use of prescription opioids (NMUPO) and its association with co-occurring substance use disorders in a sample of adolescents in substance treatment. METHODS: Adolescents in two substance treatment programs were recruited for participation between 2009 and 2013. The Composite International Diagnostic Interview-Substance Abuse Module (CIDI-SAM) was administered to assess substance use patterns and lifetime abuse or dependence. RESULTS: A total of 378 adolescents completed the CIDI-SAM (mean age 16.1 [standard deviation = 1.1], 78% male, 50% white, non-Hispanic). Of the 378 adolescents, 62 (16.4%) reported NMUPO and 59 (15.6%) were diagnosed with opioid/heroin abuse or dependence. The mean age at first NMUPO was 14.3 (standard deviation = 1.4). NMUPO was associated with a 3.31-fold (95% confidence interval: 2.83-3.79) increase in having three or more co-occurring substance use diagnoses. CONCLUSIONS: NMUPO is quite prevalent among adolescents in substance use treatment. Intervention to interrupt NMUPO from progressing to heroin use or developing into a disorder is critical.

AB - This study describes the first ever utilization of cell free aqueous extract of cyanobacterium Leptolyngbya JSC-1 as a source of strong reducing and stabilizing agents for the optimal biofabrication of gold nanoparticles (AuNPs) through an eco-friendly synthetic route. Well dispersed crystalline AuNPs of spherical morphology with a particle size of 100-200 nm were prepared. FTIR spectral analysis was then performed to characterize the possible functionalities of JSC-1 extract, mainly involved in stabilizing and formation of AuNPs. Based on the redox potential of JSC-1 extract, it was further confirmed that the extract provide a strong reducing environment in the reaction medium and causes reduction of gold ions. The resultant AuNPs were then explored to find out their photo catalytic activity for methylene blue and antibacterial activities against E. coli (18 +/- 2 mm) and S. aureus (14 +/- 2 mm). It has been mechanistically identified that AuNPs caused bacterial membrane damage and cell disruption by inducing the production of intracellular reactive oxygen species (ROS). Together, these finding reveals that biochemically capped AuNPs are the promising antibacterial agents that induce oxidative stress in the two bacterial species evaluated and cause their membrane disruption leading to cell leakage and death. PMID- 29174699 TI - Neoteric advancement in TB drugs and an overview on the anti-tubercular role of peptides through computational approaches. AB - Tuberculosis (TB) is a devastating threat to human health whose treatment without the emergence of drug resistant Mycobacterium tuberculosis (M. tuberculosis) is the million-dollar question at present. The pathogenesis of M. tuberculosis has been extensively studied which represents unique defence strategies by infecting macrophages. Several anti-tubercular drugs with varied mode of action and administration from diversified sources have been used for the treatment of TB that later contributed to the emergence of multidrug-resistant tuberculosis (MDR TB) and extensively drug-resistant tuberculosis (XDR-TB). However, few of potent anti-tubercular drugs are scheduled for clinical trials status in 2017-2018. Peptides of varied origins such as human immune cells and non-immune cells, bacteria, fungi, and venoms have been widely investigated as anti-tubercular agents for the replacement of existing anti-tubercular drugs in future. In the present review, we spotlighted not only on the mechanisms of action and mode of administration of currently available anti-tubercular drugs but also the recent comprehensive report of World Health Organization (WHO) on TB epidemic, diagnosis, prevention, and treatment. The major excerpt of the study also inspects the direct contribution of different computational tools during drug designing strategies against M. tuberculosis in order to grasp the interplay between anti-tubercular peptides and targeted bacterial protein. The potentiality of some of these anti-tubercular peptides as therapeutic agents unlocks a new portal for achieving the goal of end TB strategy. PMID- 29174700 TI - Sub-inhibitory concentrations of fluoroquinolones increase conjugation frequency. AB - Bacteria are subjected to sub-minimal inhibitory concentrations (sub-MIC) of antibiotics in various niches where the low-dosage treatment plays a key role in antibiotic resistance selection. However, the mechanism of sub-MIC of antibiotics on the resistant gene transfer is largely unknown. Here, we used Escherichia coli SM10lambdapir in which the RP4 plasmid was chromosomally-integrated as the donor strain, to investigate the effects of sub-MIC of Ciprofloxacin(Cip) or Levofloxacin(Lev) on conjugational transfer of mobilisable plasmid-pUCP24T from SM10lambdapir to Pseudomonas aeruginosa. The results showed that the transfer frequency was significantly increased by treating E. coli with sub-MIC of Cip or Lev. To investigate the molecular mechanisms, complete transcriptome sequencing was performed. We found that the sub-MIC of Cip or Lev enhanced the expression of several genes on the RP4 plasmid, which was consistent with the conjugation efficiency. Moreover, the expression of genes associated with SOS response in donor SM10lambdapir was increased, but had no correlation with conjugation efficiency. These findings suggested that sub-MIC of Cip or Lev may promote conjugational transfer by up-regulating the expression of conjugation associated genes via an SOS-independent mechanism. PMID- 29174701 TI - Tadpoles fed supplemented diet with probiotic bacterium isolated from the intestinal tract of bullfrog Lithobates catesbeianus: Haematology, cell activity and electron microscopy. AB - The aim of this study is to select and isolate autochthonous bacteria with probiotic potential for use in a supplemented diet for bullfrog tadpoles, Lithobates catesbeianus. A total of 20 strains of lactic acid bacteria were isolated. Nine out of these were used in the following in vitro assays: antagonism against pathogenic bacteria (ANT), antimicrobial activity from extracellular compounds (MIC), tolerance to bile salts (TBS), pH reduction, protease production, sensitivity to antimicrobial tetracycline, cell viability, growth rate and doubling time. Using these data was defined an ideotype (ideal strain) based on the best results. Distances were estimated with the Mahalanobis (D2) test, and the best candidates, presenting the shortest ideotype distances, were considered to be used. The best strain was found to be Lactobacillus plantarum because it presented 10.00 +/- 0.50 mm of ANT against Aeromonas hydrophila, 3.99 +/- 0.01 of MIC independent of pathogenic bacteria, 85.07 +/- 0.01 of TBS, 4.20 +/- 0.02 of final pH, 17.67 +/- 1.15 of protease production, 13.50 +/- 2.00 sensitivity to antimicrobial tetracycline, 9.36 +/- 0.04 of cell viability, 0.20 +/- 0.00 of growth rate and 3.46 +/- 0.00 doubling time. Therefore this probiotic candidate was then supplemented (2.045 +/- 1.07 * 107 colony forming unities. g-1) into the diets of bullfrog tadpoles for a period of 42 days. At the end of the trial, samples of blood and intestines were collected to verify the haematological alterations and the intestinal morphology using transmission and scanning electron microscopy. Tadpoles fed the supplemented diet showed successful lactic acid bacterium colonisation, an increased number of circulating thrombocytes, monocytes, eosinophil and LG-PAS+ and also an increase in the length and density of intestinal microvilli. This study shows the feasibility of using probiotics isolated from farmed bullfrogs as a supplement in the diets of tadpoles, providing a promising alternative for modulating the health of these animals. PMID- 29174702 TI - Cytokine induction of peripheral blood mononuclear cells by biofilms and biofilm supernatants of Granulicatella and Abiotrophia spp. AB - Granulicatella and Abiotrophia species are the normal oral flora bacteria that can occasionally cause infective endocarditis. Although substantial data exists in the literature demonstrating occurrence of these species in infective endocarditis, only a few mechanistic studies on their pathogenicity are found. The aim of this study was to investigate the ability of Granulicatella and Abiotrophia species to elicit immune response from human peripheral blood mononuclear cells (PBMC). Biofilms and biofilm supernatants of Granulicatella elegans CCUG 38949, Granulicatella adiacens CCUG 27809 and Abiotrophia defectiva CCUG 27639 were used to stimulate PBMCs for 24 h. Cytokines produced were first screened using a human cytokine membrane array kit. Further, pro-inflammatory cytokines TNF-alpha, IL-beta, and IL-17 were quantified by ELISA. The cytokine profiler array showed the induction of 15 different cytokines/chemokines including IL-1beta, IL-6, IL-8, TNF-alpha, MCP-1, MIP-1alpha/MIP-1beta and RANTES. ELISA quantification revealed that G. adiacens biofilm induced significantly higher (P < 0.05) levels of IL-1beta, i.e., 1931 (183) pg/ml than G. elegans or A. defectiva. However, in the case of biofilm supernatants A. defectiva was the strongest, inducing 2104 (574) pg/ml. Biofilm supernatants, but not biofilms from all three species induced TNF-alpha only weakly. IL-17 was undetectable from any of the stimulated samples. In conclusion, Granulicatella and Abiotrophia are potent inducers of inflammatory mediators from human PBMCs. However, biofilms and biofilm supernatants from these species seem to selectively elicit stimulation of certain cytokines. PMID- 29174703 TI - Heterogeneity of cytolethal distending toxin sequence types of Campylobacter jejuni and correlation to invasion/cytotoxicity potential: The first molecular survey from Iran. AB - The aim of this study was to evaluate the cytotoxicity and attachment/invasion potential of thermophilic Campylobacter isolates regarding their cdtABC sequence types and virulence-associated gene content. A total of 33 Campylobacter spp. were identified from 750 stool samples isolated from patients characterized with diarrhea. The prevalence rates of flaA, ciaB, and pldA genes among the isolates were 97, 100, and 15%, respectively. The iam gene was found in 100% of the C. coli isolates while it was not detected in C. jejuni isolates. Four PCR primer pairs jointly amplifying the entire cdtABC genes array and sequence analysis revealed variations dispersed along the sequence array. The isolates attachment to HeLa cells ranged from 89 +/- 2-100%, and the range of invasions was also from 0 to 11 +/- 0.04%. The cytotoxicity value was between 2 and 32 in cdt+ isolates with no significant correlation to any of the cdtABC sequence types. Moreover, the cdtABC encoding strains had increased invasion to HeLa cells, and all of the related patients presented much higher white and red blood cell shedding in stool specimens (P-value<= 0.001). No significant difference was observed between cdt+ and cdt- isolates in their attachment rate to HeLa cells. About 48% of all the Iranian Campylobacter population lacked a complete set of cdtABC genes array, suggesting low invasion and cytotoxicity potential of the isolates which are heterogeneous in their cdt genes and virulence. PMID- 29174704 TI - Diagnostic and therapeutic approach to the hypertensive crisis. AB - High blood pressure is a problem with elevated prevalence in the world population. The acute forms of presentation are "hypertensive crises," which represent a frequent cause for emergency room and primary care consultations. Hypertensive crises are divided into hypertensive emergencies and hypertensive urgencies, depending on whether or not there is acute damage to the target organ, respectively. Each situation has a different prognosis and treatment. More specifically, hypertensive emergencies are potentially serious and usually require rapid reductions in blood pressure, whereas hypertensive urgencies can be treated as outpatients by reducing blood pressure in hours or days. A significant number of patients who consult medical professionals regarding a hypertensive crisis do not have a prior diagnosis of hypertension; therefore, it is important to periodically monitor blood pressure levels in the community. PMID- 29174705 TI - Associations between ECG changes and echocardiographic findings in patients with acute non-ST elevation myocardial infarction. AB - BACKGROUND: ST segment depression (STD) and T wave inversion (TWI) are typical electrocardiographic (ECG) findings in non-ST elevation myocardial infarction (NSTEMI). In ST elevation myocardial infarction, ST changes represent transmural ischemia. The pathophysiological mechanisms of the ECG changes in NSTEMI are unclear. PURPOSE: We studied the associations between ECG and the echocardiographic findings in NSTEMI patients. METHODS: Twenty patients with acute NSTEMI were recruited during their hospital stay. A comprehensive echocardiography study was performed. The findings were compared with blinded ECG analyses. RESULTS: Nine (45%) patients had STD, and 16 (85%) patients had TWI. In multivariable analysis, STD was independently associated with a lower global early diastolic strain rate (beta=-5.061, p=0.033). TWI was independently associated with lower circumferential strain (beta=0.132, p=0.032). CONCLUSIONS: The typical ECG changes in NSTEMI patients were associated with subtle echocardiographic changes. STD was related to changes in diastolic function, and TWI was associated with systolic deterioration. PMID- 29174706 TI - Electrocardiographic scores of severity and acuteness of myocardial ischemia predict myocardial salvage in patients with anterior ST-segment elevation myocardial infarction. AB - BACKGROUND: Terminal "QRS distortion" on the electrocardiogram (ECG) (based on Sclarovsky-Birnbaum's Grades of Ischemia Score) is a sign of severe ischemia, associated with adverse cardiovascular outcome in ST-segment elevation myocardial infarction (STEMI). In addition, ECG indices of the acuteness of ischemia (based on Anderson-Wilkins Acuteness Score) indicate myocardial salvage potential. We assessed whether severe ischemia with or without acute ischemia is predictive of infarct size (IS), myocardial salvage index (MSI) and left ventricular ejection fraction (LVEF) in anterior versus inferior infarct locations. METHODS: In STEMI patients, the severity and acuteness scores were obtained from the admission ECG. Based on the ECG patients were assigned with severe or non-severe ischemia and acute or non-acute ischemia. Cardiac magnetic resonance (CMR) was performed 2 6days after primary percutaneous coronary intervention (pPCI). LVEF was measured by echocardiography 30days after pPCI. RESULTS: ECG analysis of 85 patients with available CMR resulted in 20 (23%) cases with severe and non-acute ischemia, 43 (51%) with non-severe and non-acute ischemia, 17 (20%) with non-severe and acute ischemia, and 5 (6%) patients with severe and acute ischemia. In patients with anterior STEMI (n=35), ECG measures of severity and acuteness of ischemia identified significant and stepwise differences in myocardial damage and function. Patients with severe and non-acute ischemia had the largest IS, smallest MSI and lowest LVEF. In contrast, no difference was observed in patients with inferior STEMI (n=50). CONCLUSIONS: The applicability of ECG indices of severity and acuteness of myocardial ischemia to estimate myocardial damage and salvage potential in STEMI patients treated with pPCI, is confined to anterior myocardial infarction.

PMID- 29174708 TI - Outcomes following completion and salvage surgery for early rectal cancer: A systematic review. AB - OBJECTIVES: To establish outcomes after completion and salvage surgery following local excision in literature published since 2005, to inform decision-making when offering local excision. BACKGROUND: Local excision of early rectal cancer aims to offer cure while maintaining quality of life through organ preservation. However, some patients will require radical surgery, prompted by unexpected poor pathology or local recurrence. Consistent definition and reporting of these scenarios is poor. We propose the term "salvage surgery" for recurrence after local excision and "completion surgery" for poor pathology. METHODS: Electronic databases were searched in February 2016. Studies since 2005 describing outcomes for radical surgery following local excision of rectal cancer were included. Pooled and average values were obtained. RESULTS: A total of 23 studies included 262 completion and 165 salvage operations. Most completion operations were done within 4 weeks; local recurrence rate was 5% and overall disease recurrence rate was 14%. The majority of salvage operations for local recurrence were within 15 months of local excision, often following adjuvant treatment. Re-do local excision was used in 15%; APR was the most common radical procedure. Further local recurrence was uncommon (3%) but overall disease recurrence rate was 13%. Estimated 5-year survival was in the order of 50%. Heterogeneity was high among the studies. CONCLUSIONS: Patients undergoing local excision must be informed of risks and expected outcomes, but better data on completion and salvage surgery are required to achieve this.

PMID- 29174709 TI - Exome sequencing of synchronously resected primary colorectal tumours and colorectal liver metastases to inform oncosurgical management. AB - BACKGROUND: Next generation sequencing technology has facilitated mapping of the colorectal cancer genotype and furthered our understanding of metastogenesis. The aim of this study was to investigate for conserved and different mutations in the exomes of synchronously resected primary colorectal tumour and liver metastases. This information could potentially be utilised to guide the treatment of advanced disease with the help of biological information from the primary tumour. METHODS: We performed exome sequencing of synchronously resected primary colorectal cancer and colorectal liver metastases as well as normal colonic mucosa and liver parenchyma, from four patients who had received neo-adjuvant chemotherapy, at a depth of 50X using the Ion Proton platform. Raw data was mapped to the reference genome prior to variant calling, annotation and downstream analysis. RESULTS: Exome sequencing identified 585 non-synonymous missense single nucleotide variants (SNVs), of which 215 (36.8%) were unique to the primary tumour, 226 (38.6%) unique to the metastasis and 81 (13.8%) present in patient matched pairs. SNVs identified in the ErbB pathway appear to be concordant between primary and metastatic tumours. CONCLUSION: Only 13.8% of the metastatic exome can be predicted by the genotype of the primary tumour. We have demonstrated concordance of a number of SNVs in the ErbB pathway, which may inform selection of therapeutic agents in advanced colorectal cancer. PMID- 29174710 TI - Understanding the impact and challenges of secondary data analysis. AB - Secondary data analysis is commonly defined as the use of datasets, which were not collected for the purpose of the scientific hypothesis being tested. Examples of datasets range from private insurance claims to nationally administered health surveys. The use of secondary data confer several benefits, most notably by eliminating many of the financial and logistical obstacles related to primary data collection. The issues in using secondary data to answer important clinical and health policy questions are complex, but with appropriate and rigorous approaches there is an opportunity to produce high-effect research which can improve the care of patients with urologic malignancies. PMID- 29174711 TI - High immunoexpression of Ki67, EZH2, and SMYD3 in diagnostic prostate biopsies independently predicts outcome in patients with prostate cancer. AB - INTRODUCTION: Overtreatment is a major concern in patients with prostate cancer (PCa). Prognostic biomarkers discriminating indolent from aggressive disease in prostate biopsy are urgently needed. We aimed to evaluate the prognostic value of Ki67, EZH2, LSD1, and SMYD3 immunoexpression in diagnostic biopsies from a cohort of PCa patients with long term follow-up. MATERIALS AND METHODS: A series of 189 consecutive prostate biopsies diagnosed with PCa (1997-2001) in a cancer center was included in the study, with follow-up last updated in November 2016. Biopsies were reviewed and graded according to 2016 WHO criteria. Immunohistochemistry was performed in the most representative block. Nuclear staining was assessed using digital image analysis. Study outcomes included disease-specific, disease-free, and progression-free survival. Statistical analysis was tabulated using SPSS version 22.0. Survival curves and hazard ratios (HRs) were estimated using Kaplan Meyer and Cox-regression models, respectively. Statistical significance was set at P<0.05. RESULTS: The proportion of patients who completed the study was 177/189 (94%). In univariable analysis, high Ki67, EZH2, and SMYD3 immunoexpression associated with significantly worse disease-specific survival (HR = 1.86, 95% CI: 1.05-3.29; HR = 1.87, 95% CI: 1.10-3.27; HR = 2.68, 95% CI: 1.02-7.92). In multivariable analysis, the 3 biomarkers displayed significantly worse DSS adjusted for CAPRA score (HR = 1.78, 95% CI: 1.01-3.16; HR = 1.93, 95% CI: 1.12-3.32; HR = 2.71, 95% CI: 1.04-7.10). Among patients with low/intermediate risk CAPRA score, high Ki67 immunoexpression identified those more prone to experience disease recurrence (HR = 9.20, 95% CI: 1.27-66.44) and progression (HR = 2.97, 95% CI: 1.05-8.43). CONCLUSIONS: High Ki67, EZH2, and SMYD3 immunoexpression, adjusted for standard clinicopathological parameters, independently predicts outcome in patients with PCa, at diagnosis. This might assist in discriminating indolent from aggressive PCa, improving treatment selection. PMID- 29174712 TI - Lugol Chromoendoscopy Detects Esophageal Dysplasia With Low Levels of Sensitivity in a High-Risk Region of China. AB - BACKGROUND & AIMS: Chromoendoscopy with Lugol dye is used to screen for early stage esophageal squamous dysplasia (ESD) and esophageal cancer. However, the sensitivity with which Lugol chromoendoscopy detects ESD or esophageal cancer has not been fully assessed in large populations in China. METHODS: From 2012 to 2016, a total of 15,264 residents in rural Hua County, Henan Province, which is a high-incidence area of esophageal cancer in China, were screened by Lugol chromoendoscopy. Biopsies were collected from endoscopically visualized lesions, identified before and after Lugol chromoendoscopy, and analyzed histologically. Biopsies were also collected from standard sites in the esophagus (28 and 33 cm distal to the incisors) if no abnormalities were found. We calculated the sensitivity with which Lugol chromoendoscopy detects esophageal dysplasia and carcinoma, using findings from biopsy analysis as the reference standard. RESULTS: A total 586 participants were found by biopsy analysis to have ESD or more severe lesions. After endoscopy images were reviewed twice, Lugol chromoendoscopy sensitivity values for the detection of mild, moderate, and severe dysplasia, and esophageal cancer, were 45.9%, 55.3%, 87.0%, and 97.7%, respectively. ESDs were most frequently missed by Lugol chromoendoscopy in younger patients and men with moderate levels of dysplasia. CONCLUSION: In a screening analysis of a general population in China, we found Lugol chromoendoscopy to identify individuals with ESD with lower levels of sensitivity (46%-87%) than previously believed, although it identified patients with esophageal cancer with almost 98% sensitivity. Prospective studies are needed to evaluate the clinical significance of esophageal lesions that are not detected by endoscopy.

AB - The detailed analysis of the chronic care plans developed by the Spanish regional health services show a surprising level of uniformity in their design and deployment, despite differences between these services. The reviews about theoretical models that support it and tools they develop does not provide conclusive evidence to support the chronic care models achieve better results than another alternatives of care. Although the whole Spanish chronic care plans includes assessment proposals no rigorous studies on their effect have been published to date. Given that, on the contrary, there is a strong and repeated evidence that health systems with Primary Care high performance obtains better outcomes, it is necessary to ask about the need to look for alternative models, when the proposed goals could be reached strengthen Primary Care. PMID- 29174715 TI - The co-occurrence of adverse childhood experiences among children investigated for child maltreatment: A latent class analysis. AB - Children investigated for maltreatment are particularly vulnerable to experiencing multiple adversities. Few studies have examined the extent to which experiences of adversity and different types of maltreatment co-occur in this most vulnerable population of children. Understanding the complex nature of childhood adversity may inform the enhanced tailoring of practices to better meet the needs of maltreated children. Using cross-sectional data from the National Survey of Child and Adolescent Well-Being II (N=5870), this study employed latent class analysis to identify subgroups of children who had experienced multiple forms of maltreatment and associated adversities among four developmental stages: birth to 23 months (infants), 2-5 (preschool age), 6-10 (school age), and 11-18 years-old (adolescents). Three latent classes were identified for infants, preschool-aged children, and adolescents, and four latent classes were identified for school-aged children. Among infants, the groups were characterized by experiences of (1) physical neglect/emotional abuse/caregiver treated violently, (2) physical neglect/household dysfunction, and (3) caregiver divorce. For preschool-aged children, the groups included (1) physical neglect/emotional abuse/caregiver treated violently, (2) physical neglect/household dysfunction, and (3) emotional abuse. Children in the school-age group clustered based on experiencing (1) physical neglect/emotional neglect and abuse/caregiver treated violently, (2) physical neglect/household dysfunction, (3) emotional abuse, and (4) emotional abuse/caregiver divorce. Finally, adolescents were grouped based on (1) physical neglect/emotional abuse/household dysfunction, (2) physical abuse/emotional abuse/household dysfunction, and (3) emotional abuse/caregiver divorce. The results indicate distinct classes of adversity experienced among children investigated for child maltreatment, with both stability across developmental periods and unique age-related vulnerabilities. Implications for practice and future research are discussed. PMID- 29174716 TI - Interaction of HLA-DRB1* alleles and CTLA4 (+49 AG) gene polymorphism in Autoimmune Thyroid Disease. AB - Autoimmune Thyroid Diseases (AITDs), including Hashimoto's thyroiditis (HT) and Graves' disease (GD), arise by the complex interaction of genes and environmental factors. The aim of present study was to study the susceptible associations of HLA-DRB1* alleles and CTLA4 +49 AG polymorphism in AITD in south India. AITD patients (n=235; HT=180; GD=55) and age/sex matched healthy controls (n, 235) were enrolled to type HLA-DRB1* alleles and 'CTLA4 +49 AG' by PCR-SSP and PCR RFLP methods respectively. Analysis revealed CTLA4 +49 'GG' genotype was increased significantly in patients (PL: p=8.7*10-8; HT: p=9.3*10-6; GD: p=0.006). Decreased frequencies of 'AA' genotype was observed in patients (PL: p=9.4*10-6; HT: p=0.008; GD: p=9.0*10-6). Increased frequencies were observed for HLA alleles DRB1*12 (PL: p=1.42*10-10; HT: p=5.75*10-8; GD: p=0.002) and DRB1*11 (PL: p=0.0025; HT: p=0.013) in patients. Decreased frequencies for alleles DRB1*10 (PL: p=0.00002; HT: p=0.018; GD: p=1.63*10-5) and DRB1*03 (PL: p=0.003; HT: p=0.003) were observed, suggesting a protective association. Combinatorial/Synergistic analysis have revealed an increased frequencies for 'DRB1*11+AG' (PL: p=0.022), 'DRB1*12+AG' (PL: p=6.1*10-5; HT: p=0.0001), 'DRB1*04+GG' (PL: p=0.003; HT: p=0.008), 'DRB1*07+GG' (PL: p=0.009; HT: p=0.014) and 'DRB1*12+GG' (PL: p=0.005; HT: p=0.005) in patients. However, the combinations such as 'DRB1*10+AA' (PL: p=1.8*10-6; HT: p=0.003) and 'DRB1*15+AA' (PL: p=0.006; GD: p=0.011) were decreased in patients showing a protective association. The 'GG/G' of CTLA4 +49AG SNP, HLA-DRB1*11/-DRB1*12 (DR5) alleles and the combinations of DRB1*11/DRB1*12 alleles with AG/GG genotype and DRB1*04/07/12 alleles with GG genotype may act as synergistic manner to confer the strong susceptibility to AITD in south India. PMID- 29174717 TI - Comparison of CyTOF assays across sites: Results of a six-center pilot study. AB - For more than five years, high-dimensional mass cytometry has been employed to study immunology. However, these studies have typically been performed in one laboratory on one or few instruments. We present the results of a six-center study using healthy control human peripheral blood mononuclear cells (PBMCs) and commercially available reagents to test the intra-site and inter-site variation of mass cytometers and operators. We used prestained controls generated by the primary center as a reference to compare against samples stained at each individual center. Data were analyzed at the primary center, including investigating the effects of two normalization methods. All six sites performed similarly, with CVs for both Frequency of Parent and median signal intensity (MSI) values<30%. Increased background was seen when using the premixed antibody cocktail aliquots at each site, suggesting that cocktails are best made fresh. Both normalization methods tested performed adequately for normalizing MSI values between centers. Clustering algorithms revealed slight differences between the prestained and the sites-stained samples, due mostly to the increased background of a few antibodies. Therefore, we believe that multicenter mass cytometry assays are feasible. PMID- 29174719 TI - Contaminant source identification using semi-supervised machine learning. AB - Identification of the original groundwater types present in geochemical mixtures observed in an aquifer is a challenging but very important task. Frequently, some of the groundwater types are related to different infiltration and/or contamination sources associated with various geochemical signatures and origins. The characterization of groundwater mixing processes typically requires solving complex inverse models representing groundwater flow and geochemical transport in the aquifer, where the inverse analysis accounts for available site data. Usually, the model is calibrated against the available data characterizing the spatial and temporal distribution of the observed geochemical types. Numerous different geochemical constituents and processes may need to be simulated in these models which further complicates the analyses. In this paper, we propose a new contaminant source identification approach that performs decomposition of the observation mixtures based on Non-negative Matrix Factorization (NMF) method for Blind Source Separation (BSS), coupled with a custom semi-supervised clustering algorithm. Our methodology, called NMFk, is capable of identifying (a) the unknown number of groundwater types and (b) the original geochemical concentration of the contaminant sources from measured geochemical mixtures with unknown mixing ratios without any additional site information. NMFk is tested on synthetic and real-world site data. The NMFk algorithm works with geochemical data represented in the form of concentrations, ratios (of two constituents; for example, isotope ratios), and delta notations (standard normalized stable isotope ratios). PMID- 29174718 TI - Z-FA-FMK demonstrates differential inhibition of aquatic orthoreovirus (PRV), aquareovirus (CSRV), and rhabdovirus (IHNV) replication. AB - Benzyloxycarbonyl-phenylalanyl-alanyl-fluoromethyl ketone (Z-FA-FMK) is a protease inhibitor that has been shown to strongly inhibit mammalian orthoreovirus replication. Here we explore the ability of Z-FA-FMK to inhibit three important yet genetically discrete aquatic fish viruses: chum salmon aquareovirus (CSRV), piscine orthoreovirus (PRV), and the rhabdovirus infectious hematopoietic necrosis virus (IHNV). Z-FA-FMK significantly attenuated CSRV in vitro transcription and infectious yield following low-dose (2-20MUM) exposure, yet a relatively high dose (200MUM) was required to completely block CSRV replication. For PRV and IHNV, no significant attenuation of in vitro viral transcription was observed following low-dose (2-20MUM) exposure; and although high dose (200MUM) exposure significantly attenuated both PRV and IHNV transcription, neither was completely inhibited. These transcriptional results were similarly reflected in IHNV infectious titre observed at 7days post exposure. PRV titre is currently undeterminable in vitro; however, in vivo intra peritoneal injection of PRV into juvenile Atlantic salmon (Salmo salar) in conjunction with 1.5mg/kg Z-FA-FMK did not affect PRV replication as measured by blood associated viral transcripts at 14days post challenge. These results indicate that aquatic ortho- and aqua-reoviruses appear to possess resilience to Z-FA-FMK relative to mammalian orthoreoviruses and suggest that environmental parameters or alternative mechanisms for viral replication may affect the efficacy of Z-FA-FMK as an antireoviral compound. Further, as Z-FA-FMK has been shown to irreversibly inhibit cysteine proteases such as cathepsins B and L in vitro at concentrations of <=100MUM, continued replication of IHNV (and possibly PRV) at 200MUM Z-FA-FMK suggests that replication of these viruses can occur in a cathepsin-independent manner whereas CSRV likely requires cathepsins or similar cysteine proteases for successful replication. PMID- 29174720 TI - Fungal feruloyl esterases: Functional validation of genome mining based enzyme discovery including uncharacterized subfamilies. AB - Feruloyl esterases (FAEs) are a diverse group of enzymes that specifically catalyze the hydrolysis of ester bonds between a hydroxycinnamic (e.g. ferulic) acid and plant poly- or oligosaccharides. FAEs as auxiliary enzymes significantly assist xylanolytic and pectinolytic enzymes in gaining access to their site of action during biomass saccharification for biofuel and biochemical production. A limited number of FAEs have been functionally characterized compared to over 1000 putative fungal FAEs that were recently predicted by similarity-based genome mining, which divided phylogenetically into different subfamilies (SFs). In this study, 27 putative and six characterized FAEs from both ascomycete and basidiomycete fungi were selected and heterologously expressed in Pichia pastoris and the recombinant proteins biochemically characterized to validate the previous genome mining and phylogenetical grouping and to expand the information on activity of fungal FAEs. As a result, 20 enzymes were shown to possess FAE activity, being active towards pNP-ferulate and/or methyl hydroxycinnamate substrates, and covering 11 subfamilies. Most of the new FAEs showed activities comparable to those of previously characterized fungal FAEs. PMID- 29174721 TI - Adjuvant breast radiotherapy: How to trade-off cost and effectiveness? AB - INTRODUCTION: A series of health economic evaluations (HEE) has analysed the efficiency of new fractionation schedules and techniques for adjuvant breast radiotherapy. This overview assembles the available evidence and evaluates to what extent HEE-results can be compared. METHODS: Based on a systematic literature review of HEEs from 1/1/2000 to 30/10/2016, all cost comparison (CC) and cost-effectiveness analyses (CEA) comparing different adjuvant breast radiotherapy approaches were analysed. Costs were extracted and converted to Euro 2016 and costs per QALY were summarized in cost-effectiveness planes. RESULTS: Twenty-four publications are withheld, comparing different fractionation schedules and/or irradiation techniques or evaluating the value of adding radiotherapy. Normofractionation and intensity-modulated, interstitial or intraluminal techniques are important cost-drivers. Highest reimbursements are observed in the US, but may overestimate the real cost. Hypofractionation is cost effective compared to normofractionation, the results of partial breast irradiation are less unequivocal. Intra-operative and external beam approaches seem the most cost-effective for favourable risk groups, but whole breast irradiation is superior in terms of health effect and omission of radiotherapy in terms of costs. CONCLUSION: Hypofractionation may be considered the most relevant comparator for new strategies in adjuvant breast radiotherapy, with omission of radiotherapy as an interesting alternative in the very favourable subcategories, especially for partial breast techniques. Although comparison of CC and CEA is hampered by the variability in clinical and economic settings, HEE-based evidence can guide decision-making to tailor-made strategies, allocating the optimal treatment in terms of effectiveness as well as efficiency to the right indication. PMID- 29174722 TI - Functional progression of patients with neurological diseases in a tertiary paediatric intensive care unit: Our experience. AB - INTRODUCTION: Neurological diseases explain a considerable proportion of admissions to paediatric intensive care units (PICU), and are a significant cause of morbidity and mortality. This study aims to analyse the functional progression of children with critical neurological conditions. MATERIAL AND METHODS: Retrospective descriptive study of children admitted to PICU with neurological diseases over a period of 3 years (2012-2014), assessing vital and functional prognosis at PICU discharge and at one year according to the Pediatric Cerebral and Overall Performance Category scales (PCPC-POPC) and the Functional Status Scale (FSS). The results are compared with our previous data (1990-1999), and those of the international multicentre PANGEA study. RESULTS: A total of 266 children were studied. The mortality rate was 3%; the PRISM-III and PIM2 models did not show predictive ability. Clinically significant worsening was observed in functional health at discharge in 30% of the sample, according to POPC, 15% according to PCPC, and 5% according to FSS. After one year, functional performance improved according to PCPC-POPC, but not according to FSS. Children with no underlying neurological disease had a higher degree of functional impairment; this was prolonged over time. We observed a decrease in overall and neurocritical mortality compared with our previous data (5.60 vs. 2.1%, P=.0003, and 8.44 vs. 2.63%, P=.0014, respectively). Compared with the PANGEA study, both mortality and cerebral functional impairment in neurocritical children were lower in our study (1.05 vs. 13.32%, P<.0001, and 10.47% vs. 23.79%, P<.0001, respectively). CONCLUSIONS: Nearly one-third of critically ill children have neurological diseases. A significant percentage, mainly children without underlying neurological diseases, had a clinically significant functional impact at PICU discharge and after a year. Neuromonitoring and neuroprotection measures and the evaluation of functional progression are necessary to improve critical child care. PMID- 29174723 TI - Corrections.

PMID- 29174727 TI - Evaluation of a multidisciplinary burn care journal club: Lessons learned. AB - BACKGROUND: Journal clubs allow discussion of the quality and findings of recent publications. However, journal clubs have not historically been multidisciplinary. Burn care is recognized as a true collaborative care model, including regular multidisciplinary rounds. Since 2011 we have offered a multidisciplinary burn journal club at our institution. We present an evaluation of the factors that have made the sessions successful to facilitate others to commence their own club. METHODS: At the end of each journal club session participants anonymously completed a structured evaluation. Five-point scales were used to evaluate understanding, meeting objectives, presentation and appropriateness of information. Qualitative questions were asked to identify beneficial factors, suggestions for improvements, ideas for future sessions and feedback for the facilitator. RESULTS: Attendance grew from six to a maximum of 19. Members included physicians, nurses, dieticians, physiotherapists, occupational therapists, social workers, basic scientists and students. Presentations were undertaken by all of these disciplines. Ratings improved steadily over time. Understanding increased from a score of 4.5 to 4.8; meeting objectives from 4 to 4.9; satisfaction with method of presentation from 4.3 to 4.9 and with level of information from 3 to 4.9. CONCLUSIONS: Over time, the journal club has evolved to better meet the needs of our team. Successful multidisciplinary journal club implementation requires identification of champions and ongoing evaluation. APPLICABILITY OF RESEARCH TO PRACTICE: The success of the journal club has been possible through the engagement of the entire burn team. Champions within each discipline, facilitated discussion and evaluation tools have helped nurture a nonthreatening team based learning environment. PMID- 29174728 TI - Brain activity elicited by viewing pictures of the own virtually amputated body predicts xenomelia. AB - BACKGROUND: Xenomelia is a rare condition characterized by the persistent desire for the amputation of physically healthy limbs. Prior studies highlighted the importance of superior and inferior parietal lobuli (SPL/IPL) and other sensorimotor regions as key brain structures associated with xenomelia. We expected activity differences in these areas in response to pictures showing the desired body state, i.e. that of an amputee in xenomelia. METHODS: Functional magnetic resonance images were acquired in 12 xenomelia individuals and 11 controls while they viewed pictures of their own real and virtually amputated body. Pictures were rated on several dimensions. Multivariate statistics using machine learning was performed on imaging data. RESULTS: Brain activity when viewing pictures of one's own virtually amputated body predicted group membership accurately with a balanced accuracy of 82.58% (p = 0.002), sensitivity of 83.33% (p = 0.018), specificity of 81.82% (p = 0.015) and an area under the ROC curve of 0.77. Among the highest predictive brain regions were bilateral SPL, IPL, and caudate nucleus, other limb representing areas, but also occipital regions. Pleasantness and attractiveness ratings were higher for amputated bodies in xenomelia. CONCLUSIONS: Findings show that neuronal processing in response to pictures of one's own desired body state is different in xenomelia compared with controls and might represent a neuronal substrate of the xenomelia complaints that become behaviourally relevant, at least when rating the pleasantness and attractiveness of one's own body. Our findings converge with structural peculiarities reported in xenomelia and partially overlap in task and results with that of anorexia and transgender research. PMID- 29174729 TI - Prevalence of the Clostridium difficile BI/NAP1/027 strain across the United States Veterans Health Administration. AB - OBJECTIVES: The increased incidence and severity of Clostridium difficile infection (CDI) are thought to result partly from the emergence of the hypervirulent BI/NAP1/027 strain. Limited recent data are available on the prevalence of BI/NAP1/027 in the United States (US). The objective of this study was to assess the recent prevalence of BI/NAP1/027 within the US Veterans Health Administration (VHA). METHODS: Patients with CDI at any Veterans Affairs Medical Center found to routinely test for the presence of BI/NAP1/027 during the study period were included between 1 June 2011 and 30 June 2016 in this retrospective, observational, nationwide study. RESULTS: In total, 7571 patients had 8224 positive C. difficile tests that had a corresponding BI/NAP1/027 test. Of those, there were 1810 (22.0%) presumptive positive for BI/NAP1/027. The overall prevalence of BI/NAP1/027 decreased from a high of 26.2% in 2013 to 16.9% in 2016. Statistically significant reductions in rates from 2012 to 2016 occurred in seven of nine US Census Bureau regions. CONCLUSIONS: The prevalence of C. difficile with the BI/NAP1/027 strain was 22.0% across the VHA between 2012 and 2016. Further studies are needed to confirm these results and for continued monitoring of the trends in BI/NAP1/027 prevalence. PMID- 29174730 TI - How to: identify non-tuberculous Mycobacterium species using MALDI-TOF mass spectrometry. AB - BACKGROUND: The implementation of MALDI-TOF MS for microorganism identification has changed the routine of the microbiology laboratories as we knew it. Most microorganisms can now be reliably identified within minutes using this inexpensive, user-friendly methodology. However, its application in the identification of mycobacteria isolates has been hampered by the structure of their cell wall. Improvements in the sample processing method and in the available database have proved key factors for the rapid and reliable identification of non-tuberculous mycobacteria isolates using MALDI-TOF MS. AIMS: The main objective is to provide information about the proceedings for the identification of non-tuberculous isolates using MALDI-TOF MS and to review different sample processing methods, available databases, and the interpretation of the results. SOURCES: Results from relevant studies on the use of the available MALDI-TOF MS instruments, the implementation of innovative sample processing methods, or the implementation of improved databases are discussed. CONTENT: Insight about the methodology required for reliable identification of non-tuberculous mycobacteria and its implementation in the microbiology laboratory routine is provided. IMPLICATIONS: Microbiology laboratories where MALDI-TOF MS is available can benefit from its capacity to identify most clinically interesting non-tuberculous mycobacteria in a rapid, reliable, and inexpensive manner. PMID- 29174732 TI - Disinhibition in learning and memory circuits: New vistas for somatostatin interneurons and long-term synaptic plasticity. AB - Neural circuit functions involve finely controlled excitation/inhibition interactions that allow complex neuronal computations and support high order brain functions such as learning and memory. Disinhibition, defined as a transient brake on inhibition that favors excitation, recently appeared to be a conserved circuit mechanism implicated in various functions such as sensory processing, learning and memory. Although vasoactive intestinal polypeptide (VIP) interneurons are considered to be the main disinhibitory cells, recent studies highlighted a pivotal role of somatostatin (SOM) interneurons in inhibiting GABAergic interneurons and promoting principal cell activation. Interestingly, long-term potentiation of excitatory input synapses onto hippocampal SOM interneurons is proposed as a lasting mechanism for regulation of disinhibition of principal neurons. Such regulation of network metaplasticity may be important for hippocampal-dependent learning and memory. PMID- 29174731 TI - Increased hippocampal fissure width is a sensitive indicator of rat hippocampal atrophy. AB - OBJECTIVES: Volume loss within the hippocampus is known as the most replicated finding of structural brain imaging studies of neuropsychiatric diseases. Although voxel-based auto or semi-auto volumetric measurements are widely used in the determination of the human hippocampus, the detection of hippocampal atrophy in rats is still a dilemma as it relies on a relatively primitive and complex approach. In this study, we aimed to develop a convenient way to measure the atrophy of the hippocampus in rats. METHODS: Twenty-four male Wistar rats were exposed to chronic unpredictable mild stress (CUMS) and a wheel running test (WRT) to simulate the conditions of hippocampal volume atrophy and improvement. The hippocampal volume and hippocampal fissure (HiF) width were dynamically measured using 7 T structural magnetic resonance imaging (MRI) with the grayscale method at week 0, 2, 4, and 8. The changes in the hippocampal volume and HiF width in rats were compared. In addition, hematoxylin-eosin (HE) staining of the HiF was used to verify the MRI findings. RESULTS: The hippocampal volume and the HiF width presented opposite trends based on the MRI findings and the histology data. The atrophy of the hippocampal subfields was closely related to the corresponding increase in the HiF width. CONCLUSION: Determination of the HiF width may serve as a sensitive and convenient indicator of rat hippocampal atrophy.

AB - Self-collected rectal-swabs were tested for CT and NG on GeneXpert CT/NG as compared to APTIMA Combo2. Of 448 rectal-swabs, 22 were positive for CT; 7 for NG on both assays; two were discordant. Sensitivity and specificity of GeneXpert was 95.5% and 99.7% for chlamydia, respectively; for gonorrhea both were 100%. PMID- 29174734 TI - rpoB gene sequencing highlights the prevalence of an E. miricola cluster over other Elizabethkingia species among UK cystic fibrosis patients. AB - Difficulties in distinguishing species of the Elizabethkingia genus by MALDI-TOF prompted use of rpoB sequencing to investigate species distribution among 44 isolates from cystic fibrosis (CF) patients. Forty-three isolates from 38 patients formed a cluster comprising E. miricola and proposed novel species E. bruuniana sp. nov., the exception clustering with proposed species E. ursingii sp. nov., also part of this wider cluster. All 44 isolates were PCR-positive for urease gene ureG, whereas only one of 23 E. anophelis isolates from non-CF patients was positive, suggesting that this gene is largely associated with the E. miricola cluster. Antibiotic susceptibilities of 12 CF isolates revealed all were resistant to beta-lactams with the exception of piperacillin-tazobactam, and were only susceptible to minocycline and co-trimoxazole. Pulsed-field gel electrophoresis analysis revealed 4 shared strains among 17 CF patients in one pediatric clinic, but epidemiological investigations did not support patient-to patient transmission except between one sibling pair. PMID- 29174735 TI - Comparative study of 3 carbapenem-hydrolysis methods for the confirmation of carbapenemase production in Enterobacteriaceae. AB - The goals of the study were to examine the analytic and performance parameters of 2 commercial rapid carbapenem-hydrolysis assays, the beta-CARBA test (Bio-Rad) and the Rapid CARB Blue Kit (ROSCO) in comparison with an in-house CARBA NP assay for the detection of Carbapenemase-Producing Enterobacteriaceae (CPE). Their performance was evaluated following growth on 2 chromogenic CPE screening media. The sensitivity was highest (91%) in the beta-CARBA test when used from the mSuperCARBATM plates and was lowest when the same test was used from the chromIDTM CARBA plates (75%). The specificity was highest in the NP CARBA test in both media (96%), followed by the beta CARBA/mSuperCARBATM combination (92%). The specificity of the Rapid CARB Blue Kit was as low as 36% when used with the chromIDTM CARBA plates. The beta-CARBA test was simple to use and had the shortest turn-around time and hand-on time. PMID- 29174736 TI - Protein kinase A mediates scopolamine-induced mTOR activation and an antidepressant response. AB - BACKGROUND: Clinical reports have shown that scopolamine produces a rapid (3-4 d) and potent anti-depressive response without severe adverse effects. Animal experiments have proven that scopolamine induces mTOR pathway activation in an AMPAR dependent manner. The present study aimed to determine the role of PKA in scopolamine-induced potentiation of AMPAR, as well as in mTOR pathway activation and rapid antidepressant effects. METHODS: We utilized electrophysiological recording, Western blotting, and behavior tests to examine the effects of scopolamine, the selective M2 cholinergic receptor antagonist methoctramine, and H89, a PKA specific inhibitor on AMPAR potentiation, mTOR pathway activation, and behavioral responses in a rat depression model of learned helplessness. RESULTS: Scopolamine (1MUM) rapidly increased AMPAR-fEPSP amplitudes and membrane GluA1 expression in CA1 region of hippocampal slices, both of which were abolished by H89. Moreover, scopolamine promoted AMPAR phosphorylation on GluA1 ser845, a PKA site involved in GluA1 membrane insertion. H89 disrupted both GluA1 ser845 phosphorylation and mTOR activation, as well as the antidepressant effects of scopolamine as determined via forced swim test. Additionally, methoctramine mimicked the effects of scopolamine on phosphorylation and counter-depressive action in a PKA-dependent manner. LIMITATIONS: Only one test was used to evaluate depressive behavior, and gene knock-out rats were not yet utilized to refine our hypotheses. CONCLUSION: Our findings revealed that PKA pathway is necessary for scopolamine-induced synaptic plasticity and mTOR pathway activation, and indicated that a potential M2-PKA mechanism underlies scopolamine's antidepressant effects. Such findings suggest that GluA1 ser845 phosphorylation may be a trigger event for scopolamine's actions, and that PKA may represent a novel target for the treatment of depressive symptoms. PMID- 29174737 TI - The role of media in preventing student suicides: A Hong Kong experience. AB - INTRODUCTION: In view of the surge of student suicides in March 2016, a large scale media involvement was engaged to minimize copycat effects and to extensively spread more preventive information. METHODS: Trend differences between student suicides in overall as well as youth suicides between 2003 and 2016 were examined. Impacts of media involvement were examined as to the changes of their intensities in reporting student suicides in different manners. Local polynomial smoothing method was used to estimate the intensities throughout the study period. RESULTS: The intensity of students' suicides has been slowly increasing since 2006, which was in contrast to the decreasing trend of overall suicide intensity. After our engagement with the media, acute descriptive reporting in student suicide news has sharply dropped and remained low since then, whereas preventive-reporting has increased sharply in March and April 2016, but dropped back to normal afterwards. The higher intensity of preventive reporting seemed to have a protective effect on student suicide. LIMITATIONS: Data of student suicides in 2016 were substantially extracted from the local news, which may not contain complete information. The analyses suggested, but could not confirm, a causal relationship between the changes of student suicide news-reporting and the incidents of suicides themselves. CONCLUSIONS: The recent surge of student suicides in Hong Kong was statistically abnormal. Media engagement has changed local suicide news-reporting to become more preventive, which could have contributed to the drop of student suicides. It is essential to sustain the media's coverage of preventive reporting to maintain its enduring effect. PMID- 29174738 TI - Symptoms and functioning with aripiprazole once-monthly injection as maintenance treatment for bipolar I disorder. AB - BACKGROUND: Effects of maintenance treatment with aripiprazole once-monthly 400mg (AOM 400) on symptoms and functioning were assessed in adults with bipolar I disorder (BP-I) after a manic episode. METHODS: Patients were stabilized on oral aripiprazole, cross-titrated to AOM 400, then randomized in a 52-week, double blind, placebo-controlled, withdrawal phase. Prespecified secondary outcomes are reported: time to hospitalization for mood episode, Young Mania Rating Scale (YMRS), Montgomery-Asberg Depression Rating Scale (MADRS), Clinical Global Impression-Bipolar scale, Functioning Assessment Short Test (FAST), and Brief Quality of Life in Bipolar Disorder questionnaire. Time to hospitalization for mood episode was analyzed using log-rank test and changes from baseline using mixed model for repeated measures or analysis of covariance. RESULTS: AOM 400 significantly increased time to hospitalization for any mood episode versus placebo (P=0.0002). YMRS total scores decreased with oral aripiprazole; improvements were maintained with AOM 400. After randomization, YMRS scores changed little with AOM 400 but worsened with placebo (P=0.0016), and MADRS scores, already low at trial initiation, did not differ between groups. FAST score improvements were maintained with AOM 400 but not placebo (P=0.0287). LIMITATIONS: Results are generalizable to patients with BP-I stabilized on aripiprazole following a manic episode. CONCLUSIONS: Patients with BP-I experiencing an acute manic episode exhibited symptomatic and functional improvements during stabilization with oral aripiprazole and AOM 400 that were maintained with continued AOM 400 treatment but not placebo. AOM 400 is the first once-monthly long-acting injectable antipsychotic to demonstrate efficacy in maintenance treatment of the manic phase of BP-I. PMID- 29174739 TI - Episode accumulation associated with hastened recurrence and delayed recovery in bipolar disorder. AB - AIMS: Assess episode accumulation (>= 10 prior mood episodes) associations with demographic/baseline clinical characteristics and mood episode recurrence/recovery in bipolar disorder (BD). METHODS: Stanford BD Clinic outpatients enrolled during 2000-2011 were assessed with Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation. Among recovered and syndromal mood episode patients, we assessed episode accumulation associations with demographic/baseline clinical characteristics and with recurrence/recovery (by Kaplan-Meier survival analyses, with mediators assessed with Cox Proportional Hazard Ratio (HR) analyses). RESULTS: Among all 450 BD outpatients, almost twice as many had versus lacked episode accumulation (65.8% versus 34.2%), which was less common among 92 recovered versus 193 syndromal mood episode patients (51.1% versus 69.9%). Among recovered patients, episode accumulation was associated with 14/18 (77.7%) demographic/other baseline clinical characteristics, and hastened mood episode recurrence. Among syndromal mood episode patients, episode accumulation was associated with 13/18 (72.2%) demographic/other baseline clinical characteristics, and delayed mood episode recovery. LIMITATIONS: American tertiary BD clinic referral sample. CONCLUSION: Studies are needed to confirm episode accumulation is associated with hastened mood episode recurrence and delayed mood episode recovery in BD, and to further explore its' associations with hastened mood elevation recurrence and delayed recovery from depressive and mood elevation episodes, considered separately.

This finding is supported by magnetic resonance imaging (MRI)-based meta-analysis that show volume reductions in circumscribed areas of the brain in patients with MD. Using optical coherence tomography (OCT), retinal changes have been demonstrated in neurodegenerative disorders. In light of this inflammatory/degenerative hypothesis, we tested whether patients with MD exhibit retinal alterations that might correlate with the severity and duration of the disease. METHODS: Patients with MD and age- and gender-matched healthy controls were recruited for the measurement of the total volume and thickness of their retina as well as the thicknesses and volumes of five different retinal layers using single-layer analysis provided by the spectral-domain-OCT. RESULTS: OCT data from 28 patients with MD and 20 healthy controls were available for evaluation. The exploratory intra-individual group comparison of the two eyes showed a small but significant difference in the retinal total volume (right = 8.69mm3; left = 8.72mm3; p = 0.03) only in patients with MD. There were no other significant differences between the patients with MD and the healthy controls with respect to the OCT measurements. LIMITATIONS: The small group size as well as the absence of correction for multiple testing due to the exploratory design should be considered as limitations of our study. CONCLUSION: While retinal total volume differs between the eyes of patients with MD, the comparison of retinal parameters between these patients and age- and gender-matched healthy volunteers did not show any differences. PMID- 29174741 TI - Antidepressant-like effect of zileuton is accompanied by hippocampal neuroinflammation reduction and CREB/BDNF upregulation in lipopolysaccharide challenged mice. AB - BACKGROUND: Recent studies demonstrated beneficial effects of zileuton, a 5 lipoxygenase (5LO) inhibitor, on some brain diseases in animal models, but the role of zileuton in the depression remains unknown. METHODS: We investigated the effects of zileuton on depressive behaviors using tail suspension test (TST), forced swimming test (FST) and novelty-suppressed feeding test (NSFT) in mice injected with lipopolysaccharide (LPS). The 5LO level, activation of microglia, NF-kappaB p65, TNF-alpha, IL-1beta, brain-derived neurotrophic factor (BDNF), and c-AMP response element-binding protein (CREB) were determined in the mouse hippocampus. RESULTS: We firstly found that the expression of hippocampal 5LO was gradually increased over LPS exposure and was reversed by fluoxetine administration. Zileuton significantly suppressed LPS-induced depressive behaviors, evidenced by the decreases in immobility time in TST and FST, as well as the latency to feed in NSFT. This treatment pronouncedly alleviated LPS induced neuroinflammatory response, characterized by decreased 5LO, suppressed activation of microglia, decreased NF-kappaB p65, TNF-alpha and IL-1beta, and significantly increased the ratio of p-CREB/CREB or mBDNF/proBDNF in the hippocampus of the LPS-challenged mice. CONCLUSIONS: Zileuton abrogates LPS induced depressive-like behaviors and neuroinflammation, and enhances CREB/BDNF signaling in the hippocampus, suggesting that zileuton could have potential therapeutic value for depression. PMID- 29174742 TI - Predictors and outcomes of somatization in bipolar I disorder: A latent class mixture modeling approach. AB - BACKGROUND: Mood disorders are often associated with somatic symptoms. The role of somatic symptoms on disease progression in unipolar depression is substantially better characterized than that role in bipolar disorder. Moreover, the contribution of comorbid anxiety disorders and medical illness is not well understood. METHOD: We investigated 527 patients with bipolar I disorder clustered within 102 families using a latent class approach. Predictors were added stepwise into the model. Anxiety and commonly associated medical illnesses were added as covariates. RESULTS: The rate of somatic symptoms in this sample was 73% (mean 1.7 symptoms), and 27.3% had a comorbid anxiety disorder. A two class model, with a subgroup at high-risk for somatization, gave the best fit to the data. Multilevel mixture modeling accounted for family clusters. Somatic symptoms were independently associated with disease severity, defined as earlier age of first seeking psychiatric help (x = 21.7 vs x = 24.7, p = 0.005) and first psychiatric hospitalization (x = 25.7 vs x = 28.2, p = 0.03), greater probability of attempting suicide (x = 0.41 vs x = 0.32, p = 0.047), and rapid-cycling disease course (x = 0.57 vs x = 0.36, p < 0.001). Persons with few or no somatic symptoms were more likely to be hospitalized for severe mania (x = 0.63 vs x = 0.51; p = 0.013), but did not significantly differ in hospitalization for severe depression. LIMITATIONS: The study is correlational. Information on pharmacologic interventions and comorbid diseases was limited. CONCLUSIONS: Somatic symptoms in bipolar disorder could be an independent indicator for disease severity, suicidality, and rapid-cycling disease course. In severe mental illness, somatic and psychological symptoms must be jointly addressed. PMID- 29174743 TI - Prefrontal glutamatergic emotion regulation is disturbed in cluster B and C personality disorders - A combined 1H/31P-MR spectroscopic study. AB - BACKGROUND: Personality disorders (PD) belong to the most common and most serious mental disorders as regards social dysfunction, inability to work, occurrence of comorbidity and suicidal risk. PDs also crucially influence the incidence, clinical course and treatment response of mental disorders with high suicidal risk, such as depression or substance abuse. One key issue of PD concerns the regulation of emotions. METHODS: Both 1H-/31P-Chemical Shift Imaging (CSI) was applied in a single session to assess neurochemical markers of glutamate function (NAA, Glu) and local energy metabolism (PCr, ATP) in two patient cohorts encompassing 22 cluster B (CB) and 21 cluster C (CC) PD patients, whereby 10 patients of each group were on low-dose antidepressants, and in 60 healthy controls (HC). Non-parametric statistical tests and correlation analyses were performed to assess disease effects on the metabolites and their relation to symptomatology as assessed by SCL-90R self-ratings. RESULTS: Overall comparison including Bonferroni correction revealed significant differences of Glu across all groups in the dorsolateral prefrontal cortex (DLPFC). The following uncorrected results of pairwise tests were obtained: (i) Glu was bilaterally increased in the DLPFC in CB patients, whereas it was - together with NAA - bilaterally decreased in the DLPFC in CC patients and accompanied by increased PCr in the left DLPFC. (ii) NAA and Glu, accompanied by increased PCr, were significantly decreased in the dorsomedial prefrontal cortex (DMPFC) in CC patients. (iii) NAA was decreased in the right anterior cingulate cortex (ACC) in CB patients, and in the left ACC in CC patients with PCr being increased bilaterally. (iv) No associations were observed between metabolites and psychopathology measures. CONCLUSION: The observations in the DLPFC may reflect a neurobiochemical correlate of disturbed cognitive control function in CB and CC PD. While the alterations in CB patients suggest increased basal activity, the observed patterns in CC patients likely reflect decreased or inhibited activity. The alterations of NAA and Glu levels in the ACC and DMPFC indirectly support the assumption of disturbed neuronal function in regions involved in social cognition and mentalizing abilities in both CB and CC PD. Further studies should include the investigation of metabolites of neuronal inhibition (GABA) and the examination of treatment effects. PMID- 29174744 TI - Distinguishing transient versus stable aspects of depression in New Zealand Pacific Island children using Generalizability Theory. AB - BACKGROUND: The distinction between temporary versus enduring or state/trait aspects of depression is important. More precise distinction would improve understanding of the aetiology of depression and those aspects most amenable to intervention thus identifying more homogeneous, dynamic targets for clinical trials. Generalizability Theory has been proposed as useful for disentangling state and trait components of psychopathology. METHODS: We applied Generalizability Theory to determine the relative contributions of temporary and enduring aspects of depression in a widely used screening measure of depression the - 10-item Children's Depression Inventory (CDI-10; Kovacs, 1985). Participants were children of Pacific Island descent living in New Zealand (n = 668). Data were collected at ages - 9, 11, and 14 years. RESULTS: The CDI-10 demonstrated acceptable generalizability across occasions (G = 0.79) with about one third of variance in total scores attributed to temporary and two thirds to more enduring aspects of depression. There were no other significant sources of error variance. Two items were identified as more sensitive than the remaining eight to more dynamic symptoms. LIMITATIONS: Studies with briefer test-retest intervals are warranted. Use of this Pacific Island cohort limits generalizability of findings to other cultures and ethnicities. No data were collected on whether participants had received intervention for depression. CONCLUSIONS: While the CDI-10 reliably measures both stable and transient aspects of depression in children, the scale does not permit clear distinction between them. We advocate application of Generalizability Theory for developing state/trait depression measures and determining which existing measures are most suitable for capturing modifiable features of depression. PMID- 29174745 TI - Stroke After Transcatheter Aortic Valve Replacement: Incidence, Definitions, Etiologies and Management Options. AB - Neurologic complications after transcatheter aortic valve replacement are devastating. The etiologies of stroke in this setting are best addressed in an integrated fashion during each phase of the perioperative pathway. The conduct of this triphasic approach will continue to be refined to reduce the stroke risks even further, given the major focus on aspects such as embolic protection devices and valve thrombosis. This neurologic focus in transcatheter aortic valve replacement has transformed the investigational approach to neurologic events in cardiovascular clinical trials, resulting in novel guidelines for the diagnosis and assessment of neurologic injury after cardiovascular interventions. PMID- 29174746 TI - Evaluating the Effect on Mortality of a No-Tranexamic acid (TXA) Policy for Cardiovascular Surgery. AB - OBJECTIVES: The authors stopped using tranexamic acid (TXA) in April 2013. The present study aimed to examine the impact of a "no-TXA-use" policy by comparing the adverse effects of TXA and clinical outcomes before and after the policy change in patients undergoing cardiovascular surgery. DESIGN: A single center retrospective cohort study. SETTING: A single cardiovascular center. PARTICIPANTS: Patients undergoing cardiovascular surgery between January 2008 and July 2015 (n = 3,535). INTERVENTIONS: Patients' outcomes before and after the policy change were compared to evaluate the effects of the change. MEASUREMENTS AND MAIN RESULTS: The seizure rate decreased significantly after the policy change (6.9% v 2.7%, p < 0.001). However, transfusion volumes and blood loss volumes increased significantly after the policy change (1,840 mL v 2,030 mL, p = 0.001; 1,250 mL v 1,372 mL, p < 0.001, respectively). Thirty-day mortality was not statistically different (1.6% v 1.4%, p = 0.82), nor were any of the other outcomes. Propensity-matched analysis and segmented regression analysis showed similar results. CONCLUSIONS: The mortality rate remained the same even though the seizure rate decreased after the policy change. Blood loss volume and transfusion volume both increased after the policy change. TXA use provides an advantageous benefit by reducing the need for blood transfusion. PMID- 29174747 TI - Validation of a Mathematical Model of Bidirectional Glenn Circulation With Aortopulmonary Collaterals and the Implications for QP/QS Calculation. AB - OBJECTIVES: A mathematical model of the oxygen delivery kinetics of the bidirectional Glenn (BDG) shunt circulation incorporating aortopulmonary collateral (APC) flow was created. The model was used to characterize oxygen delivery and compare modeled data to actual patient data obtained using cardiac magnetic resonance imaging (MRI) and catheterization. In addition, cardiac MRI and catheterization assessment of pulmonary blood flow in the presence of APC flow were compared. DESIGN: Mathematical model and retrospective data analysis of patients who underwent cardiac MRI and catheterization. The mathematical model is based on the concept that APC flow to the lungs is recirculated pulmonary venous blood flow, which does not contribute to systemic oxygen delivery. SETTING: Single-center, university teaching hospital. PARTICIPANTS: The study included 98 patients with BDG shunt undergoing cardiac MRI and cardiac catheterization. MEASUREMENTS AND MAIN RESULTS: In the absence of APC flow, the pulmonary blood flow to systemic blood flow ratio (Qp/Qs) calculated using cardiac catheterization data closely matched that obtained with cardiac MRI. In the presence of APC flow, Qp/Qs calculated using cardiac catheterization data systematically underestimated values obtained with cardiac MRI. A mathematical model of BDG shunt oxygen delivery incorporating variable APC flow was created. The model provided reasonable prediction of actual patient data for arterial blood oxygen, superior vena cava oxygen saturation, and oxygen delivery obtained at the time of cardiac catheterization in patients. CONCLUSION: The oxygen delivery kinetics of a BDG shunt incorporating variable APC flow can be modeled mathematically. Model output can be used to predict blood oxygen saturation after coil embolization of APC flow in the cardiac catheterization laboratory.

PMID- 29174749 TI - Takotsubo Cardiomyopathy Following Induction of Anesthesia for Lung Transplantation, an Unexpected Complication. PMID- 29174750 TI - Assessment of Pulmonary Edema: Principles and Practice. AB - Pulmonary edema increasingly is recognized as a perioperative complication affecting outcome. Several risk factors have been identified, including those of cardiogenic origin, such as heart failure or excessive fluid administration, and those related to increased pulmonary capillary permeability secondary to inflammatory mediators. Effective treatment requires prompt diagnosis and early intervention. Consequently, over the past 2 centuries a concentrated effort to develop clinical tools to rapidly diagnose pulmonary edema and track response to treatment has occurred. The ideal properties of such a tool would include high sensitivity and specificity, easy availability, and the ability to diagnose early accumulation of lung water before the development of the full clinical presentation. In addition, clinicians highly value the ability to precisely quantify extravascular lung water accumulation and differentiate hydrostatic from high permeability etiologies of pulmonary edema. In this review, advances in understanding the physiology of extravascular lung water accumulation in health and in disease and the various mechanisms that protect against the development of pulmonary edema under physiologic conditions are discussed. In addition, the various bedside modalities available to diagnose early accumulation of extravascular lung water and pulmonary edema, including chest auscultation, chest roentgenography, lung ultrasonography, and transpulmonary thermodilution, are examined. Furthermore, advantages and limitations of these methods for the operating room and intensive care unit that are critical for proper modality selection in each individual case are explored.

AB - BACKGROUND: Ischemic heart disease is the leading cause of death in the United States and the world. Advanced age is the strongest risk factor for ischemic heart disease and the best independent predictor for poor outcomes after acute coronary syndrome (ACS). Elderly patients are at high risk for ACS, and numerous studies have shown that octogenarians in particular experience increased morbidity and mortality compared to younger patients. CASE REPORT: We describe a case of an 83-year-old woman who presented to the emergency department with a chief complaint of sore throat and was found to have a non-ST elevation myocardial infarction (NSTEMI) and was treated successfully with primary coronary intervention (PCI). WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Chest pain is a common presenting symptom for ACS, but elderly patients with MI are more likely to present with other chief complaints. Only 40% of patients in the National Registry of Myocardial Infarction database >= 85 years of age had chest pain on initial presentation. Recent studies comparing invasive therapy (PCI or coronary artery bypass graft) with optimal medical therapy for patients > 75 years of age diagnosed with NSTEMI have reported a reduced risk of death and major cardiac events with invasive therapy. Emergency physicians should have a high level of suspicion for ACS in octogenarians, even in those presenting without chest pain. Timely diagnosis and management can improve morbidity and mortality in these patients.

PMID- 29174754 TI - A Randomized Controlled Trial of a Single Dose Furosemide to Improve Respiratory Distress in Moderate to Severe Bronchiolitis. AB - BACKGROUND: Bronchiolitis is one of the most common disorders of the lower respiratory tract in infants. While historically diuretics have been used in severe bronchiolitis, no studies have looked directly at their early use in children in the emergency department. OBJECTIVE: The primary objective of this study was to determine whether a single early dose of a diuretic in infants with moderate to severe bronchiolitis would improve respiratory distress. Secondary objectives examined whether it reduced the use of noninvasive ventilation and hospital length of stay. METHODS: Patients diagnosed with clinical bronchiolitis were enrolled at a tertiary care, academic children's hospital over a 3-year period. This was a double-blind, randomized controlled trial in which subjects were randomly assigned to either furosemide or placebo. Respiratory rate and oxygen saturation at the time of medication delivery and at 2 and 4 h post intervention were recorded, as well as other data. Exact logistic regression was used to examine associations. RESULTS: There were 46 subjects enrolled and randomized. There was no difference in respiratory rates, measured as a decrease of >= 25%, at both 2 and 4 h after intervention between furosemide and placebo groups (odds ratios 1.13 and 1.13, respectively). There was also no difference in oxygen saturation, intensive care unit admission rate, or hospital length of stay between groups. CONCLUSIONS: While theoretically a single dose of a diuretic to reduce lung fluid would improve respiratory distress in children with bronchiolitis, our randomized controlled medication trial showed no difference in outcomes.

AB - OBJECT: The treatment of brachial plexus avulsion injury remains a challenging problem. Admittedly, central nervous mechanisms play a significant role in the motor recovery of the paralyzed hand after peripheral nerve surgery. The present study aimed at investigating the relationship between cerebral reorganization and motor recovery after a unique peripheral crossing nerve transfer surgery in brachial plexus injury patients. METHODS: In the present study, two brachial plexus avulsion injury patients with were followed up for 4 years after contralateral C7 nerve transfer surgery. In the surgery, an intact nerve root from the intact limb was transferred to repair the injured nerves. One patient showed a good motor recovery in the paralyzed hand while the other showed relatively poor outcomes. In the longitudinal follow-up, 9 PET scans of the brain were conducted in both patients at regular intervals of every 6 months. A correlation analysis between cerebral glucose metabolism and flexion power of the paralyzed wrists and fingers was performed to investigate the involvement of brain reorganization during the process of motor recovery. RESULTS: The cerebral glucose metabolism in the corpus callosum, premotor cortex (Broadmann Area 6) and the precuneus were found positively correlated with the motor recovery of the paralyzed hand in Patient A (P < .01). Positive correlation between the cerebral glucose metabolism and the motor recovery of the paralyze hand was only present in the corpus callosum in Patient B (P < .01). CONCLUSION: Corpus callosum, premotor cortex and precuneus were related with motor recovery after contralateral cervical nerve transfer surgery. The accumulating activation of these cortical regions potentially represented the recovery of high-order motor networks and may have facilitated the motor recovery. PMID- 29174756 TI - Differentiating meningioma grade by imaging features on magnetic resonance imaging. AB - Atypical meningioma has an aggressive clinical course. Distinguishing atypical from benign meningioma preoperatively could affect surgical planning and improve treatment outcomes. In this study, we examined whether pre-operative magnetic resonance imaging (MRI) features could distinguish between benign and atypical meningioma. Imaging factors analyzed included peritumoral edema, the presence of a draining vein, tumor necrosis, tumor location and tumor volume. Using univariate analysis, the most striking predictor of grade was tumor volume (p < .001). When adjusting for the degree of peritumoral edema, volume remained a positive predictor of higher histological grade meningioma (p = .042) and was the strongest single predictor of higher-grade meningioma in this study. Additional imaging features associated with increased risk for atypical pathology in univariate analysis included the presence of tumor necrosis (p = .012), peritumoral edema (p = .022) and location along the falx and convexity (p = .026). Despite statistically significant associations using univariate analysis, in multivariate analysis, we found that only presence of peritumoral edema was predictive of a higher-grade meningioma. Further multivariate analyses suggests that edema, draining vein and necrosis are all positive predictors of tumor volume (p < .0001). Overall, these data suggest that radiographic features including presence of tumor necrosis, and tumor location along the falx or convexity may be predictive of higher-grade meningioma when considered alone. However, most strikingly, our data point to tumor volume as the most robust pre operative indicator of higher-grade meningioma. PMID- 29174757 TI - Anterior transcorporeal tunnel approach for cervical myelopathy guided by CT based intraoperative spinal navigation: Technical note. AB - Cervical spondylotic myelopathy (CSM) is the most common degenerative disease of the spine in elderly patients. Although there are several surgical options for the treatment of this disease, minimally invasive techniques for localized decompression of the true clinical generator of the patient's disease has revolutionized spinal surgery recently. This article presents an alternate application of the anterior transcorporeal tunnel approach in combination with computed tomography (CT)-based intraoperative navigation in the treatment of patients with cervical myelopathy secondary to spondylosis. Three clinical cases are used as examples to demonstrate how this procedure can be used to decompress a localized target in cervical spondylotic myelopathy. Clinical images of each case are shown. Cervical decompression was successfully achieved in all three patients, with the improvement of preoperative symptoms. The anterior transcorporeal tunnel approach combined with the use of CT-based intraoperative spinal navigation may be a feasible minimally invasive procedure for the treatment of cervical spondylotic myelopathy in selected cases. PMID- 29174758 TI - A Proactive Approach to High Risk Delirium Patients Undergoing Total Joint Arthroplasty. AB - BACKGROUND: Delirium is a common complication among elderly patients undergoing total joint arthroplasty (TJA). Its incidence has been reported from 4% to 53%. The Centers for Medicare and Medicaid Services consider delirium following TJA a "never-event." The purpose of this study is to evaluate a simple perioperative protocol used to identify delirium risk patients and prevent its incidence following TJA. METHODS: Our group developed a protocol to identify and prevent delirium in patients undergoing TJA. All patients were screened and scored in the preoperative assessment, on criteria such as age, history of forgetfulness, history of agitation or visual hallucinations, history of falls, history of postoperative confusion, and inability to perform higher brain functions. Patients were scored on performance in a simple mental examination. The patients were classified as low, medium, or high risk. Patients who were identified as high risk were enrolled in a delirium avoidance protocol that minimized narcotics and emphasized nursing involvement and fluids administration. RESULTS: Five of 7659 (0.065%) consecutive TJA patients from 2010 to 2015 developed delirium. A total of 422 patients were identified as high risk. All 5 patients who suffered delirium were within the high risk group. No low or medium risk patients suffered a delirium complication. Three (0.039%) patients suffered drug-induced delirium, 1 (0.013%) had delirium related to alcohol withdrawal, and 1 (0.013%) had delirium after a systemic infection. CONCLUSION: This protocol is effective in identifying patients at high delirium risk and diminishing the incidence of this complication by utilizing a simple screening tool and perioperative protocol. PMID- 29174759 TI - Change in Body Mass Index After Total Knee Arthroplasty and Its Influence on Functional Outcome. AB - BACKGROUND: There is often an assumption by patients that weight loss will occur once their knee pain is relieved by total knee arthroplasty (TKA). This study aims to evaluate (1) the change in patients' body mass index (BMI) after TKA; (2) if postoperative change in BMI influences functional outcome and survival rate of TKA; and (3) the predictive factors associated with change in BMI. METHODS: Seven thousand seven hundred thirty-three patients who underwent a primary TKA between 2001 and 2010 were included in this study. Functional outcome scores collected at 2 years after surgery include the Oxford Knee Score, Knee Society Function Score, Knee Society Knee Score, Physical Component Score, and Mental Component Score of short form 36. RESULTS: Among these patients, 1067 (14%) had reduction in BMI, 5045 (65%) maintained their BMI, and 1621 (21%) had gain in BMI. The differences in improvement in Oxford Knee Score, Knee Society Function Score, Knee Society Knee Score, and Physical Component Score among the 3 groups of patients were less than the known minimal clinically important difference of these scores. The 10 year survival rate of TKA was not influenced by patients' change in BMI after surgery (P = .435). Obese class I, II, and III patients were more likely to reduce their BMI after TKA than those with normal preoperative BMI (P = .002, P = .012, and P = .004, respectively), while older patients were less likely to have gain in BMI after surgery (P = .001). CONCLUSION: A change in BMI after TKA did not influence the functional outcome clinically or the survival rate of the TKA implant. PMID- 29174760 TI - Increased Serum Ion Levels After Ceramic-on-Metal Bearing Total Hip Arthroplasty: Influence of an Asian Lifestyle. AB - BACKGROUND: Recent clinical studies have suggested that systemic metal ion levels are significantly elevated at midterm follow-up in patients with ceramic-on-metal (COM) bearing. However, it is not clear whether there is a correlation between patient-related factors including the lifestyle and elevated levels of serum metal ions following COM total hip arthroplasty (THA). METHODS: Serum metal levels were measured in 201 patients (234 hips) including 121 COM patients (140 hips) and 80 non-COM patients (94 hips). The Harris Hip Score, University of California, Los Angeles activity scale score, and Western Ontario and McMaster Universities Osteoarthritis Index score were measured and radiographs were obtained for the analysis. RESULTS: Significantly higher levels of cobalt (Co) and chromium (Cr) were detected in the serum of the COM THA group (Co: 1.86 +/- 4.0 MUg/L; Cr: 1.81 +/- 2.87 MUg/L) than those of the non-COM THA group (Co: 0.27 +/- 0.14 MUg/L; Cr: 0.19 +/- 0.25 MUg/L; P < .001). The serum metal levels of patients who achieved the squatting position and the kneeling position were significantly higher than those of patients who could not squat (Co: P = .033; Cr: P = .074) and kneel (Co: P = .049; Cr: P = .031). The metal ion levels of the COM THA group correlated with the total range of motion (Co: P = .0293; Cr: P = .0399). CONCLUSION: Patients who underwent a 36-mm COM THA showed high serum metal levels although good clinical outcomes at the midterm follow-up. We found that COM THA patients who were capable of greater range of motion, squatting, and kneeling are at risk of metal ion-related problems. PMID- 29174761 TI - Vancomycin Povidone-Iodine Protocol Improves Survivorship of Periprosthetic Joint Infection Treated With Irrigation and Debridement. AB - BACKGROUND: Irrigation and debridement with modular component and liner exchange (IDLE) is a low morbidity procedure for treatment of periprosthetic joint infection (PJI) with reported failure rates exceeding 50%. Dilute povidone-iodine lavage has been shown to be safe and effective in decreasing acute PJI in primary total joint arthroplasty. Vancomycin powder has also shown to be effective in preventing infection in spine surgery. We hypothesize that a vancomycin povidone iodine protocol (VIP) used in conjunction with IDLE can increase infection-free survivorship after acute PJI. METHODS: This is a single institution retrospective review of all PJIs treated with IDLE and VIP since March 2014. A consecutive matched control group of patients treated with IDLE for PJI for 2 years prior to March 2014 was also included for analysis. Primary outcome was failure, defined as return to operating room for an infection-related problem. Secondary outcome was chronic suppression with antibiotics at final follow-up. Minimum follow-up was 1 year. RESULTS: A total of 36 patients in the VIP group and 38 patients in control group were identified. In the VIP group, 16.7% (6/36) failed at final follow-up compared to 37% failure rate (14/38) in the control group (P < .05). Three patients in the VIP group were on chronic antibiotic suppression at final follow-up. There were no medical complications secondary to the VIP. CONCLUSIONS: The VIP group demonstrated a significant reduction in reinfection and failure rate following IDLE. The authors believe that a VIP is an effective adjunct for treating PJI with irrigation and debridement. PMID- 29174762 TI - Efficacy of Intravenous Acetaminophen for Postoperative Analgesia in Primary Total Knee Arthroplasty. AB - BACKGROUND: The use of intravenous acetaminophen has seen recent enthusiasm as one component of a multimodal approach to pain management. However, there is a lack of literature examining the efficacy of intravenous acetaminophen for pain control in total joint arthroplasty. The purpose of this study was to evaluate the efficacy of intravenous acetaminophen following primary total knee arthroplasty. METHODS: This is a retrospective review of 38 patients undergoing primary total knee arthroplasty by a single surgeon at one institution. Twenty five patients received 1 gram of intravenous acetaminophen every 6 hours for 24 hours postoperatively. Thirteen patients received no additional intervention. Exclusion criteria were bilateral or concomitant procedures, allergy to medications included in the standard postoperative protocol, neuropathy or sensory disturbances, history of opioid dependence or abuse, deviations from protocol, revision procedures, and incomplete data. Primary outcomes were change in patient-reported visual analog scale (VAS) pain score, overall opioid consumption measured in morphine milligram equivalents, and hospital length of stay. RESULTS: We found no difference in length of stay, at 3.3 days in the control group and 2.9 days in the intervention group. There was a significant difference in VAS score between 16 and 24 hours. There was a statistically significant decrease in overall opioid consumption in the intravenous acetaminophen group 37.6 vs 18.6 morphine milligram equivalents. CONCLUSION: Intravenous acetaminophen is effective in significantly reducing opioid requirements in the first 24 hours following primary total knee arthroplasty. Additionally, there is a clinically significant decrease in VAS pain scores in patients receiving this intervention. PMID- 29174763 TI - Publication Rates in Podium and Poster Presentations at the 2012-2014 American Association of Hip and Knee Surgeons Annual Meetings. AB - BACKGROUND: Subspecialty conferences are an important forum for disseminating the latest research relevant to clinical practice. The purpose of this study was to identify publication rates in podium and poster abstracts for the American Association of Hip and Knee Surgeons (AAHKS) Annual Meeting and to identify the most common journals of publication and the reasons for nonpublication. METHODS: Six hundred ten accepted abstracts (182 podium presentations, 428 posters) from the 2012-2014 AAHKS meetings were searched using Google, Google Scholar, and PubMed. If an abstract could not be found after efforts by multiple searchers, the first author was emailed to determine where the research was published or why it was not published. For articles that were published, the journal, time to publication, and journal impact factor were noted. RESULTS: The overall rate of publication was 71% (436/610). Podium presentations (164/182, 90%) were published at a higher rate than posters (271/428, 63%). The most common journal of publication was the Journal of Arthroplasty (218/436, 50%), followed by Clinical Orthopaedics and Related Research (77/436, 18%) and The Journal of Bone and Joint Surgery (40/436, 9%). Average time to publication was 14.5 months (range, -4 to 44 months) from the date of the conference in which it was presented. CONCLUSION: Presentations at the AAHKS annual meeting have an impressive rate of publication. The research presented at the meeting is impactful and high quality, warranting consideration for future publication. PMID- 29174764 TI - Evidence that reduced gray matter volume in psychotic disorder is associated with exposure to environmental risk factors. AB - The aim of this study was to examine whether cannabis use, childhood trauma and urban upbringing are associated with total gray matter volume (GMV) in individuals with (risk for) psychotic disorder and whether this is sex-specific. T1-weighted MRI scans were acquired from 89 patients with a psychotic disorder, 95 healthy siblings of patients with psychotic disorder and 87 controls. Multilevel random regression analyses were used to examine main effects and interactions between group, sex and environmental factors in models of GMV. The three-way interaction between group, sex and cannabis (chi2 =12.43, p<0.01), as well as developmental urbanicity (chi2 = 6.29, p = 0.01) were significant, indicating that cannabis use and developmental urbanicity were associated with lower GMV in the male patient group (cannabis: B= -32.54, p < 0.01; developmental urbanicity: B= -10.23, p=0.03). For childhood trauma, the two-way interaction with group was significant (chi2 = 5.74, p = 0.02), indicating that childhood trauma was associated with reduced GMV in the patient group (B=-9.79, p=0.01). The findings suggest that reduction of GMV in psychotic disorder may be the outcome of differential sensitivity to environmental risks, particularly in male patients. PMID- 29174766 TI - Brain choline in major depression: A review of the literature. AB - The focus of this review is to provide a synthesis of the current literature on the role of brain choline, as measured by proton magnetic resonance spectroscopy (1H-MRS), in major depressive disorder (MDD). The most recent 1H-MRS literature review took place over 10 years ago and, reflecting the high level of research on this topic, much has been learned since then. Higher brain choline levels have been linked to an increase in depression, and a cholinergic model for MDD development has been postulated. However, current 1H-MRS studies have been inconclusive regarding the role of choline in depression. Data from eighty-six peer-reviewed studies were analyzed for a random-effects model meta-analysis. Two significant findings are reported. Papers that did not report segmentation had a significant, moderate effect size. Higher choline concentrations in the frontal lobe were found in depressed patients, both in those who responded to treatment and those who did not, after treatment with psychiatric medication, repetitive transcranial magnetic stimulation, or electroconvulsive therapy. Findings from this review may add to existing information regarding the role of brain choline in MDD. This may provide a future target for treatment and drug development. It also may serve as a biomarker for treatment progress. PMID- 29174765 TI - Attention training modulates resting-state neurophysiological abnormalities in posttraumatic stress disorder. AB - Recent research indicates the relative benefits of computerized attention control treatment (ACT) and attention bias modification treatment (ABMT) for posttraumatic stress disorder (PTSD); however, neural changes underlying these therapeutic effects remain unknown. This study examines how these two types of attention training modulate neurological dysfunction in veterans with PTSD. A community sample of 46 combat veterans with PTSD participated in a randomized double-blinded clinical trial of ACT versus ABMT and 32 of those veterans also agreed to undergo resting-state magnetoencephalography (MEG) recordings. Twenty four veterans completed psychological and MEG assessments at pre- and post training to evaluate treatment effects. MEG data were imaged using an advanced Bayesian reconstruction method and examined using statistical parametric mapping. In this report, we focus on the neural correlates and the differential treatment effects observed using MEG; the results of the full clinical trial have been described elsewhere. Our results indicated that ACT modulated occipital and ABMT modulated medial temporal activity more strongly than the comparative treatment. PTSD symptoms decreased significantly from pre- to post-test. These initial neurophysiological outcome data suggest that ACT modulates visual pathways, while ABMT modulates threat-processing regions, but that both are associated with normalizing aberrant neural activity in veterans with PTSD. PMID- 29174767 TI - Sorcin ablation plus beta-adrenergic stimulation generate an arrhythmogenic substrate in mouse ventricular myocytes. AB - Sorcin, a penta-EF hand Ca2+-binding protein expressed in cardiomyocytes, is known to interact with ryanodine receptors and other Ca2+ regulatory proteins. To investigate sorcin's influence on cardiac excitation-contraction coupling and its role in the development of cardiac malfunctions, we generated a sorcin knockout (KO) mouse model. Sorcin KO mice presented ventricular arrhythmia and sudden death when challenged by acute stress induced by isoproterenol plus caffeine. Chronic stress, which was induced by transverse aortic constriction, significantly decreased the survival rate of sorcin KO mice. Under isoproterenol stimulation, spontaneous Ca2+ release events were frequently observed in sorcin KO cardiomyocytes. Sorcin KO hearts of adult, but not young mice developed overexpression of L-type Ca2+ channel and Na+-Ca2+ exchanger, which enhanced ICa and INCX. Consequently, spontaneous Ca2+ release events in sorcin KO cardiomyocytes were more likely to induce arrhythmogenic delayed afterdepolarizations. Our study demonstrates sorcin deficiency may trigger cardiac ventricular arrhythmias due to Ca2+ disturbances, and evidences the critical role of sorcin in maintaining Ca2+ homeostasis, especially during the adrenergic response of the heart. PMID- 29174768 TI - Acetylation of TBX5 by KAT2B and KAT2A regulates heart and limb development. AB - TBX5 plays a critical role in heart and forelimb development. Mutations in TBX5 cause Holt-Oram syndrome, an autosomal dominant condition that affects the formation of the heart and upper-limb. Several studies have provided significant insight into the role of TBX5 in cardiogenesis; however, how TBX5 activity is regulated by other factors is still unknown. Here we report that histone acetyltransferases KAT2A and KAT2B associate with TBX5 and acetylate it at Lys339. Acetylation potentiates its transcriptional activity and is required for nuclear retention. Morpholino-mediated knockdown of kat2a and kat2b transcripts in zebrafish severely perturb heart and limb development, mirroring the tbx5a knockdown phenotype. The phenotypes found in MO-injected embryos were also observed when we introduced mutations in the kat2a or kat2b genes using the CRISPR-Cas system. These studies highlight the importance of KAT2A and KAT2B modulation of TBX5 and their impact on heart and limb development. PMID- 29174769 TI - Variation in training and use of the focused assessment with sonography in trauma (FAST). AB - BACKGROUND: Training in ultrasound is variable among residents and practicing traumatologists. Focused Assessment with Sonography in Trauma (FAST) may be underused in non-urbanized areas, possibly due to lack of training. METHODS: State trauma registry data from January 2014-June 2016 were reviewed for FAST results. Trauma practitioners were surveyed querying training, confidence, and obstacles to performing FAST. RESULTS: 12,855 records revealed highest FAST use at the urban Level II center (39%, p < 0.0001). Despite similar injury patterns, non-urban/Level III centers' frequency of FAST was only 1-28%. 39 practitioners were surveyed, those with training (54%) were more likely to use FAST (p < 0.05). 61% of practitioners outside the Level II center cited lack of confidence in their ability to perform FAST as the primary reason for omitting the exam. CONCLUSIONS: FAST is relatively underused in non-urbanized areas of the state. Lack of confidence in ability to perform FAST was cited as the primary barrier. PMID- 29174770 TI - Can parathyroid hyperplasia be predicted preoperatively? AB - INTRODUCTION: The purpose of this study was to determine if there are clinical features that raise suspicion for parathyroid hyperplasia. MATERIALS & METHODS: We retrospectively reviewed patients with primary hyperparathyroidism who underwent parathyroidectomy from 1991 to 2017, analyzing demographics, calcium and PTH, and localizing studies for patients with hyperplasia and single adenoma. RESULTS: 549 patients underwent parathyroidectomy: 464 (85%) with adenoma, 44 (8%) with double adenoma, 38 (7%) with hyperplasia, and 3 (1%) with cancer. Compared to patients with a single adenoma, patients with hyperplasia were more likely to have negative sestamibi, ultrasound or both exams (92% vs 6%, p < 0.001; 96% vs 4%, p < 0.001; and 91% vs 2%, p < 0.001) and lower gland weights (619 +/- 1067 mg vs. 1466 +/- 1899 mg, p < 0.001). CONCLUSION: Parathyroid hyperplasia should be suspected in patients with lower gland weights and negative imaging. PMID- 29174771 TI - Surgery residents recognized less frequently over time by medical students: A twelve year study of the Arnold P. Gold Humanism and Excellence in Teaching Award. AB - BACKGROUND: There is a decreasing institutional percentage of surgical resident recipients of The Arnold P. Gold Humanism and Excellence in Teaching Award over time. The hypothesis was that this trend was a national phenomenon. METHODS: This was a retrospective study from 2004 - 2015, utilizing data from the Arnold P. Gold Foundation. Multiple regression was performed using the estimated ratio of eligible surgical to non-surgical residents and the year as explanatory variables, utilizing an alpha = 0.05. RESULTS: The percentage of surgical award winners was lower in the second study half compared to the first half (40.2% vs. 47.2%) (p = 0.02). Multiple regression showed that when controlling for the number of eligible residents, the number of resident awardees decreased over time (p = 0.01). CONCLUSION: There is a clear national trend that surgical residents are receiving the Arnold P. Gold Humanism and Excellence in Teaching Award less over time. PMID- 29174772 TI - Leaders by example: Best practices and advice on establishing a state-of-the art surgical simulation center that optimizes available resources. AB - BACKGROUND: The role of simulation-based education continues to expand exponentially. To excel in this environment as a surgical simulation leader requires unique knowledge, skills, and abilities that are different from those used in traditional clinically-based education. METHODS: Leaders in surgical simulation were invited to participate as discussants in a pre-conference course offered by the Association for Surgical Education. Highlights from their discussions were recorded. RESULTS: Recommendations were provided on topics such as building a simulation team, preparing for accreditation requirements, what to ask for during early stages of development, identifying tools and resources needed to meet educational goals, expanding surgical simulation programming, and building educational curricula. CONCLUSION: These recommendations provide new leaders in simulation with a unique combination of up-to-date best practices in simulation-based education, as well as valuable advice gained from lessons learned from the personal experiences of national leaders in the field of surgical simulation and education. PMID- 29174773 TI - The diagnosis and staging of pancreatic cancer: A comparison of endoscopic ultrasound and computed tomography with pancreas protocol. AB - BACKGROUND: Pancreatic cancer is the fourth leading cause of cancer-related death in United States. We compared Computed Tomography (CT) with pancreas protocol and Endoscopic Ultrasound (EUS) in terms of mass detection, mass size, vascular involvement and lymph node involvement. METHODS: We retrospectively evaluated 93 patients. Concordance between CT and EUS, and accuracy of CT and EUS were assessed using a retrospective chart review and statistical analysis. RESULTS: CT and EUS agreed on mass detection in 88% of the cases and mass size in 67% of the cases. They agreed in 74% of cases about the presence or absence of vascular involvement and 82% in lymph node involvement. Cohen's kappa indicated that the concordance between two tests was moderately reliable. CONCLUSION: CT and EUS agree moderately well in identifying characteristics of pancreatic masses, but discrepancies between the two modalities are common, particularly with respect to involvement of specific blood vessels and lymph nodes. Clinicians should use caution in relying on a single modality to make decisions. PMID- 29174774 TI - Do not break up the surgical team! Familiarity and expertise affect operative time in complex surgery. AB - BACKGROUND: The effects of replacing a surgeon's familiar, experienced certified surgical assistant (CSA) on perioperative outcomes in complex surgery were investigated. METHODS: An interrupted time series of totally laparoscopic pancreatoduodenectomies performed by a single surgeon was retrospectively studied. Segmented regression analysis estimated replacement effects on estimated blood loss (EBL) and operative time. RESULTS: The cohort was composed of the last 100 cases with the familiar CSA and the first 100 cases with the replacement CSA. Study groups were similar. Unadjusted segmented regression of operative time and EBL predicted replacement effects of 70 min (95%CI, 18-122; p = 0.008) and 114 cc (95%CI, -93-320; p = 0.3), respectively. Adjusted regression predicted replacement effects of 40 min (95%CI, 0.9-78; p = 0.04) and 27 cc (95%CI, -156 210; p = 0.3). CONCLUSIONS: The replacement of a familiar, experienced CSA was associated with longer operative times. Despite confinement to a single surgeon and procedure, these results suggest what all surgeons know: excellent help is priceless. PMID- 29174775 TI - Novel Automated Suturing Technology for Minimally Invasive Aortic Valve Replacements. AB - PURPOSE: Annular suture placement during minimally invasive right anterior thoracotomy aortic valve replacements (MI-AVR) can be challenging. We present the early clinical experience with novel automated suturing technology that may reduce the technical difficulty of this operation. DESCRIPTION: The technology presented involves an automated articulating suturing device that simultaneously drives dual-curved needles through the aortic annulus to place a pledgeted horizontal mattress suture remotely; a second device with 2 straight needles places suture through the sewing cuff of a prosthetic heart valve. EVALUATION: Automated annular suturing was used in five MI-AVR procedures, which were successfully completed, with no paravalvular leaks detected and a mean aortic valve gradient of 6.4 mm Hg postprocedure. Mean aortic cross-clamp and cardiopulmonary bypass times were 100 and 134 minutes, respectively. All 5 patients were successfully discharged home, with a mean intensive care unit and total length of stay of 2 and 7 days, respectively. CONCLUSIONS: Automated suturing during MI-AVRs is feasible and may reduce the technical challenge of this operation. Further research is necessary to determine its effect on patient outcomes. PMID- 29174776 TI - Management of Surge in Extracorporeal Membrane Oxygenation Transport. AB - BACKGROUND: Transporting patients receiving extracorporeal membrane oxygenation (ECMO) support is safe and reliable with a dedicated program and established management protocols. As our program has grown, our teams have had to adapt to manage surges in transport volume while maintaining patient safety. We assessed the outcomes at peak use of our ECMO transport services during surges. METHODS: We conducted a single-center retrospective review of all patients transported to our institution while supported with ECMO from September 2008 to September 2016. Survival to discharge was the primary outcome. Surge patients were defined as those transported during months with at least 8 transports or patients transported within 24 hours of another patient in nonsurge months. RESULTS: From 2008 to 2016, 222 patients were transported to our institution while supported with ECMO. Baseline characteristics and indices of disease severity were comparable between surge and nonsurge patients. Of the 84 patients transported during surges, 59 surge patients (70%) survived to hospital discharge vs 86 (63%) of nonsurge patients (p = 0.31). Multivariable logistic regression showed that age and APACHE II (Acute Physiology and Chronic Health Evaluation) severity index score were predictors of in-hospital death (p < 0.05), but transportation during a surge was not (odds ratio, 0.91; 95% confidence interval, 0.46 to 1.80; p = 0.79). CONCLUSIONS: Patient safety and clinical outcomes can be maintained during surges in ECMO transport volume if the ECMO program has developed plans for handling transient increases in volume and considers staff fatigue and burnout. Standardizing interhospital communication, patient selection, and management protocols are critical to maintaining quality of care. PMID- 29174777 TI - Cardiac Surgery Outcomes in Abdominal Solid Organ Transplant Recipients. AB - BACKGROUND: Cardiovascular disease is a cause of morbidity and mortality in organ transplant recipients. Cardiac surgery after organ transplantation is not uncommon in this population. We evaluated 30-day outcomes and long-term survival of abdominal transplant recipients undergoing cardiac surgery at our institution. METHODS: In all, 138 patients with previous kidney, kidney-pancreas, and liver transplants underwent cardiac surgery from 2000 to 2016. Propensity score (ratio 1:3) matched 115 abdominal transplant with 345 patients undergoing cardiac surgery without a history of abdominal transplant. They were matched for type and year of cardiac surgery, age, sex, body mass index, history of diabetes mellitus, and creatinine level before cardiac surgery. RESULTS: Median time from abdominal transplant to cardiac surgery was 7 years (interquartile range, 3 to 12 years). Perioperative variables, including surgery and cardiopulmonary bypass time, aortic cross-clamp and intubation time, and intensive care unit stay did not differ between the groups. Hospital length of stay and rate of 30-day hospital readmissions did not differ between the groups. Patients with abdominal transplants had more strokes (4% versus 0.6%; p = 0.005) within 30 days after surgery. There were no differences in renal failure, bleeding, site infections, atrial fibrillation, and pneumonia between the groups. Five patients (4%) died within 30 days after surgery in the abdominal transplant group (4 kidneys, 1 liver, 0 kidney-pancreas), and 7 patients (2%) died in the nontransplanted group (p = 0.24). CONCLUSIONS: Previous history of abdominal transplant is associated with an increased 30-day incidence of stroke after cardiac surgery. Abdominal transplant does not affect 30-day mortality after cardiac surgery, whereas long term survival is significantly reduced. Regular patient follow-up and prevention and early treatment of postoperative complications are key to patient survival. PMID- 29174778 TI - Association of Donor Tricuspid Valve Repair With Outcomes After Cardiac Transplantation. AB - BACKGROUND: Tricuspid regurgitation after cardiac transplantation is associated with worse clinical outcomes. This study sought to determine the association of donor tricuspid valve repair (dTVR) with outcomes after cardiac transplantation. METHODS: Patients who underwent cardiac transplantation between January 20, 2002, and December 31, 2016, were included. Multivariable Cox regression modeling was performed to determine the association between dTVR and the composite outcome of death, posttransplant TVR, kidney transplant after cardiac transplant, or chronic dialysis, and included propensity scoring to control for baseline differences in likelihood of undergoing dTVR. RESULTS: The analysis included 330 patients, with 173 (52.4%) undergoing dTVR. dTVR performance varied by surgeon and also increased over time, with 71 (83.5%) performed during January 1, 2011, to November 30, 2013. Transplant year and surgeon were significantly associated with the baseline likelihood of undergoing dTVR. Although fewer composite outcomes occurred in the dTVR vs no dTVR group (39 [22.5%] vs 56 [36.4%], p = 0.006), dTVR was not significantly associated with the composite outcome in multivariable modeling. Lower risk for the composite outcome was associated with greater number of biopsies during the first posttransplant year, whereas higher risk was associated with more high-grade biopsy specimens and higher creatinine. CONCLUSIONS: There was no significant benefit or harm with regards to the composite of death, posttransplant TVR, or dialysis associated with dTVR. PMID- 29174779 TI - External Suction and Fluid Output in Chest Drains After Lobectomy: A Randomized Clinical Trial. AB - BACKGROUND: Even when air leakage has ceased completely after lobectomy, chest drains are often not removed because of high fluid output. Accepted thresholds for removal vary between institutions but typically range between 200 and 500 mL/d. There is little knowledge whether external suction influences the amount of fluid. METHODS: We randomly assigned (1:1) 106 patients who underwent lobectomy to either low (-5 cm H2O) or high (-20 cm H2O) external suction using an electronic chest drainage system. Only one chest drain was allowed, and we used strict algorithms for chest drain removal, which was delegated to staff nurses: air leakage less than 20 mL/min for 6 hours regardless of fluid output, provided it was serous. The primary end point was fluid output after 24 and 48 hours. RESULTS: Mean fluid output was significantly higher with high suction after both 24 (338 +/- 265 mL versus 523 +/- 215 mL) and 48 hours (616 +/- 366 mL versus 1067 +/- 387 mL (p < 0.001). Repeated measure analysis (mixed model) demonstrated that in addition to suction level the surgical approach (video-assisted thoracoscopic surgery/thoracotomy, p = 0.04) and affected lobe (upper/lower, p = 0.001) were significant predictors of fluid production. CONCLUSIONS: Increased suction levels lead to increased fluid output. Thoracotomy and lower lobectomy are associated with increased fluid output in chest drains, which should be taken into consideration if algorithms for chest drain removal include an upper limit of fluid output. PMID- 29174780 TI - Hospitalization Costs After Surgery in High-Risk Patients With Early Stage Lung Cancer. AB - BACKGROUND: We previously reported that early stage lung cancer patients who are considered high risk for surgery can undergo resection with favorable perioperative results and long-term mortality. To further elucidate the role of surgical resection in this patient cohort, this study evaluated the length of stay and total hospitalization cost among patients classified as standard or high risk with early stage lung cancer who underwent pulmonary resection. METHODS: A total of 490 patients from our institutional Society of Thoracic Surgeons data from 2009 to 2013 underwent resection for clinical stage I lung cancer. High-risk patients were identified by American College of Surgeons Oncology Group z4032 z4099 criteria. Demographics, length of stay, and hospitalization cost between high-risk and standard-risk patients undergoing lobectomy and sublobar resection were compared. Univariate analysis was performed using the chi-square test or Fisher's exact test. Multivariate analysis was performed using a linear regressions model. RESULTS: A total of 180 (37%) of patients were classified as high risk. These patients were older (70 years of age vs. 65 years of age; p < 0.0001), had worse forced expiratory volume in 1 second (57% vs. 85%; p < 0.0001), and had worse diffusion capacity of carbon dioxide (47% vs. 77%; p < 0.0001). The baseline cost and length of stay was represented by a thoracoscopic wedge resection in a standard-risk patient. A larger extent of resection, thoracotomy, or high-risk classification increased the cost and length of stay. CONCLUSIONS: Our previous study showed that good clinical outcomes after surgery for early stage lung cancer can be achieved in patients classified as high risk. In this study, although surgery in high-risk patients led to slightly increased costs, these costs seemed negligible when viewed along with the patients' excellent short-term and long-term results. This study suggests that surgical resection on high-risk patients with early stage lung cancer is associated with acceptable hospital lengths of stay and overall cost when compared with standard risk patients. PMID- 29174781 TI - Utilization of Veno-Arterial Extracorporeal Membrane Oxygenation for Massive Pulmonary Embolism. AB - BACKGROUND: The management of massive pulmonary embolism remains challenging, with a considerable mortality rate. Although veno-arterial extracorporeal membrane oxygenation (VA-ECMO) for massive pulmonary embolism has been reported, its use as salvage therapy has been associated with poor outcomes. We reviewed our experience utilizing an aggressive, protocolized approach of VA-ECMO to triage, optimize, and treat these patients. METHODS: All patients with a massive pulmonary embolism who were placed on VA-ECMO, as an initial intervention determined by protocol, were retrospectively reviewed. ECMO support was continued until organ optimization was achieved or neurologic status was determined. At that time, if the thrombus burden resolved, decannulation was performed. If substantial clot burden was still present with evidence of right ventricular (RV) strain, operative therapy was undertaken. RESULTS: Twenty patients were identified. Before cannulation, all patients had an RV-to-left ventricular ratio greater than 1.0 and severe RV dysfunction. The median duration of ECMO support was 5.1 days, with significant improvement in end-organ function. Ultimately, 40% received anticoagulation alone, 5% underwent catheter-directed therapy, and 55% underwent surgical pulmonary embolectomy. Care was withdrawn in 1 patient with a prolonged pre-cannulation cardiac arrest after confirmation of neurologic death. In-hospital and 90-day survival was 95%. At discharge, 18 of 19 patients had normal RV function, and 1 patient, who received catheter-directed therapy, had mild dysfunction. CONCLUSIONS: VA-ECMO appears to be an effective tool to optimize end-organ function as a bridge to recovery or intervention, with excellent outcomes. This approach may allow clinicians to better triage patients with massive pulmonary embolism to the appropriate therapy on the basis of recovery of RV function, residual thrombus burden, operative risk, and neurologic status. PMID- 29174782 TI - Pericardial Blood as a Trigger for Postoperative Atrial Fibrillation After Cardiac Surgery. AB - BACKGROUND: Prevention strategies have long been sought to reduce the incidence and burden of postoperative atrial fibrillation (POAF) after heart surgery. However, none has emerged as a dominant and widely applicable prophylactic measure. The purpose of this review is to consider the biological mechanisms by which shed mediastinal blood leads to oxidation and inflammation within the postoperative pericardial environment and how this might trigger POAF in susceptible persons, as well as how it could represent a new target for prevention of POAF. METHODS: We conducted a structured research of literature using PubMed and MEDLINE databases to May 2016. Biomolecular and clinical articles focused on assessing the contribution of pericardial blood, or the resulting inflammation within the pericardial space and its potential role in triggering POAF, were included in this review. RESULTS: Evidence suggests that shed mediastinal blood through breakdown products, activation of coagulation cascade, and oxidative burst contributes to a highly pro-oxidant and proinflammatory milieu found within the pericardial space that can trigger postoperative atrial fibrillation in susceptible persons. The extent of this reaction could be blunted by reducing the exposition of pericardium to blood either through posterior pericardiotomy or improved chest drainage. CONCLUSIONS: Shed mediastinal blood undergoing transformation within the pericardium appears to be an important contributing factor to POAF. Strategies to prevent shed mediastinal blood from pooling around the heart might be considered in developing future paradigms for prevention of POAF. PMID- 29174783 TI - Improving Results of Surgery for Ebstein Anomaly: Where Are We After 235 Cone Repairs? AB - BACKGROUND: Ebstein anomaly has heterogeneous anatomy and numerous operative techniques are described. Cone repair provides a near anatomic tricuspid valve repair. The purpose of this study was to examine our experience with cone repair. METHODS: Cone repair was performed in 235 consecutive patients with Ebstein anomaly, 134 children (57%) and 101 adults (43%), from June 2007 to October 2015. Median age was 15.6 years (range, 6 months to 73 years). Cone repair was the first operation in 192 patients (82%), the second in 41 (17%), and the third in 2 (1%). Previous tricuspid valve repair had been performed in 27 (12%). Echocardiograms were obtained preoperatively and at hospital dismissal for all patients and for a subgroup of patients at least 6 months after cone repair (n = 81). RESULTS: Leaflet augmentation was done in 67 patients (28%), Sebening stitch in 57 (24.2%), neochordae in 49 (21%), and annuloplasty band in 158 (67%). Bidirectional cavopulmonary shunt was performed in 46 patients (20%). There was 1 early death (0.4%). Early reoperation was required in 14 patients (5.9%); re repair was possible in 7 (50%). The majority of early reoperations (11 of 14; 79%) occurred in the first third of the series. Mean follow-up was 3.5 +/- 2.5 years. There was sustained reduction in tricuspid regurgitation (p < 0.0001), a progressive decline in right ventricle size (p < 0.0001), and late increase in right ventricle fractional area change after initial decline (p < 0.0001). Freedom from late reoperation was 97.9% at 6 years. CONCLUSIONS: Cone repair is safe, and the learning curve is significant. Sustained reduction in tricuspid regurgitation and favorable changes in the right ventricle at follow-up suggest that cone repair has an advantageous impact on right ventricular remodeling. PMID- 29174784 TI - Colonization With Multiresistant Bacteria: Impact on Ventricular Assist Device Patients. AB - BACKGROUND: Although the effect of infections with multidrug-resistant bacteria (MDRB) in left ventricular assist device (LVAD) recipients is well characterized, the influence of perioperative colonization on the development of infections in this patient cohort remains unknown. The study evaluated the effect of MDRB colonization on patient outcomes after LVAD implantation. METHODS: We retrospectively analyzed the microbiological screening studies of nasal, throat, wound, and rectal swabs in 82 consecutive patients who received an LVAD at our center between 2010 and 2015. Four categories of MDRB were determined: methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus, and Gram-negative bacterium resistant to three or four of four predefined pharmacologic categories of antibiotics. We also compared the long-term outcome of patients with and without colonization. RESULTS: There were 28 patients (34.1%) diagnosed as being colonized with at least 1 species of an MDRB. MDRB colonization was associated with the occurrence of fatal infections from any pathogen (MDRB positive, 63.2%; MDRB negative, 34.4%; p = 0.04) and fatal MDRB specific infections (MDRB positive, 31.6%; MDRB negative, 6.3%; p = 0.04), significantly longer intensive care unit stay (p < 0.0001), and longer cumulative hospital stay (p = 0.04). CONCLUSIONS: Our study demonstrates that the colonization with MDRB is a highly prevalent risk factor for infection-associated death in the vulnerable LVAD population. Routine screening for MDRB before and after LVAD implantation should be considered to identify high-risk individuals and facilitate effective prevention of infectious complications. PMID- 29174786 TI - Endothelial Shear Stress of the Saphenous Vein Composite Graft Based on the Internal Thoracic Artery. AB - BACKGROUND: Endothelial shear stress (ESS) has been suggested as a factor affecting atherosclerosis and remodeling of native vessels and bypass conduits. We compared ESS levels of internal thoracic artery (ITA) and saphenous vein (SV) composite grafts intraoperatively and 1 year after coronary artery bypass grafting (CABG). METHODS: Intraoperative ESS was calculated by measuring flow volumes and diameters of proximal and distal ITAs and SV conduits in 23 patients who received SV Y-composite grafts based on the in situ left ITA. Early (1.2 +/- 0.5 days) and 1-year (12.9 +/- 1.1 months) postoperative angiograms were performed in 23 and 15 patients, respectively. An intragraft Doppler-guidewire study for ESS measurement was performed in 6 patients during 1-year angiography. RESULTS: Intraoperative diameters of proximal and distal ITAs and SV conduits were 2.0 +/- 0.2 mm, 1.8 +/- 0.3 mm, and 3.2 +/- 0.4 mm, respectively. ESS levels were significantly different between them (41.0 +/- 21.0, 28.4 +/- 25.2, and 4.3 +/- 3.0 dyne/cm2, respectively). Proximal and distal ITA diameters increased significantly on early angiograms and remained unchanged, but SV diameter increased to 3.7 mm (95% confidence interval, 3.5 to 4.0 mm; p < 0.001) on the early angiogram and decreased to 2.9 mm (95% confidence interval, 2.7 to 3.2 mm; p < 0.001) at 1 year. Significant correlations were found between the initial ESS and proportional changes in conduit diameters during postoperative year 1. SV ESS increased in all 6 patients at 1 year, with no significant differences in ESS levels between the 3 conduits (29.9 +/- 7.9, 28.8 +/- 7.9, and 21.6 +/- 16.3 dyne/cm2, respectively). CONCLUSIONS: Initial ESS appears to be associated with proportional changes in conduit diameters in the first year after CABG. ESS values of SV composite grafts were similar to left ITA conduits 1 year after CABG. PMID- 29174787 TI - Updated Trends in Gallbladder and Other Biliary Tract Cancers Worldwide. PMID- 29174785 TI - Determinants of Variation in Pneumonia Rates After Coronary Artery Bypass Grafting. AB - BACKGROUND: Although conventional wisdom suggests that differences in patient risk profiles drive variability in postoperative pneumonia rates after coronary artery bypass grafting (CABG), this teaching has yet to be empirically tested. We determined to what extent patient risk factors account for hospital variation in pneumonia rates. METHODS: We studied 324,085 patients undergoing CABG between July 1, 2011, and December 31, 2013, across 998 hospitals using The Society of Thoracic Surgeons Adult Cardiac Database. We developed 5 models to estimate our incremental ability to explain hospital variation in pneumonia rates. Model 1 contained patient demographic characteristics and admission status, while Model 2 added patient risk factors. Model 3 added measures of pulmonary function, Model 4 added measures of cardiac anatomy and function and medications, and Model 5 further added measures of intraoperative and postoperative care. RESULTS: Although 9,175 patients (2.83%) experienced pneumonia, the median estimated distribution of pneumonia rates across hospitals was 2.5% (25th to 75th percentile: 1.5% to 4.0%). Wide variability in pneumonia rates was evident, with some hospitals having rates more than 6 times higher than others (10th to 90th percentile: 1.0% to 6.1%). Among all five models, Model 2 accounted for the most variability at 4.24%. In total, 2.05% of hospital variation in pneumonia rates was explained collectively by traditional patient factors, leaving 97.95% of variation unexplained. CONCLUSIONS: Our findings suggest that patient risk profiles only account for a fraction of hospital variation in pneumonia rates; enhanced understanding of other contributory factors (eg, processes of care) is required to lessen the likelihood of such nosocomial infections.

PMID- 29174789 TI - Simplifying Resect and Discard Strategies for Real-Time Assessment of Diminutive Colorectal Polyps. AB - BACKGROUND & AIMS: During endoscopy, the resect and discard strategy, if performed with high confidence, can be used to determine histologic features of diminutive colorectal polyps (5 mm or less). These polyps can then be removed and discarded without pathology assessment. However, the complexities of real-time optical assessment and follow-up management have provided challenges to widespread use of this approach. We aimed to determine the outcomes of simple alternative strategies, in which all diminutive polyps can be resected and discarded. METHODS: We collected data from 2 previous studies that used narrow band imaging to assess polyps, performed at 5 medical centers (1658 patients with 2285 diminutive polyps; 15 endoscopists). We compared 3 resect and discard strategies: the currently used optical strategy, which relies on high confidence optical assessment of all diminutive polyps; a location-based strategy that classifies all recto-sigmoid diminutive polyps a priori as hyperplastic and all polyps proximal to the recto-sigmoid colon a priori as neoplastic; and a simplified optical strategy, in which all recto-sigmoid diminutive polyps are classified as hyperplastic unless confidently assessed as neoplastic, and all polyps proximal to the recto-sigmoid colon are classified as neoplastic unless confidently assessed as hyperplastic polyps. The primary outcome was the agreement of the surveillance interval calculated for each strategy with the surveillance interval determined by pathology analysis. RESULTS: The proportion of surveillance intervals that agreed with pathology-based surveillance recommendations was slightly higher when the optical strategy was used compared to the location-based strategy or simplified optical strategy (94% vs 89% and 90%, respectively; P < .001). When the 5-10 year recommendations for patients with low-risk polyps were applied as a 10-year surveillance interval, all 3 strategies resulted in surveillance interval agreement compared to pathology above 90% (the quality benchmark). Use of the simplified or location-based strategy could have avoided pathology analysis for 77% of all polyps, compared to 59% if the optical strategy was used (P < .001). In addition, a higher proportion of patients could receive recommendations immediately after colonoscopy with use of the simplified or location based strategy (65%) compared to the optical strategy (40%) (P < .001). CONCLUSION: A location-based and a simplified optical resect and discard strategy produced surveillance recommendations that were in agreement with those from pathology analysis for at least 90% of patients, assuming a 10-year surveillance interval for patients with low-risk polyps. These strategies could further reduce the number of pathology examinations and provide more patients with immediate surveillance recommendations. Optical assessment might be reduced or might not be required for resect and discard. Clintrials.gov no: NCT01935180 and NCT01288833. PMID- 29174790 TI - Towards measuring the semantic capacity of a physical medium demonstrated with elementary cellular automata. AB - The organic code concept and its operationalization by molecular codes have been introduced to study the semiotic nature of living systems. This contribution develops further the idea that the semantic capacity of a physical medium can be measured by assessing its ability to implement a code as a contingent mapping. For demonstration and evaluation, the approach is applied to a formal medium: elementary cellular automata (ECA). The semantic capacity is measured by counting the number of ways codes can be implemented. Additionally, a link to information theory is established by taking multivariate mutual information for quantifying contingency. It is shown how ECAs differ in their semantic capacities, how this is related to various ECA classifications, and how this depends on how a meaning is defined. Interestingly, if the meaning should persist for a certain while, the highest semantic capacity is found in CAs with apparently simple behavior, i.e., the fixed-point and two-cycle class. Synergy as a predictor for a CA's ability to implement codes can only be used if context implementing codes are common. For large context spaces with sparse coding contexts synergy is a weak predictor. Concluding, the approach presented here can distinguish CA-like systems with respect to their ability to implement contingent mappings. Applying this to physical systems appears straight forward and might lead to a novel physical property indicating how suitable a physical medium is to implement a semiotic system. PMID- 29174791 TI - Patient-perceived health service needs in inflammatory arthritis: A systematic scoping review. AB - BACKGROUND: Care that is patient-centred is more likely to be sustainable and associated with improved health outcomes. This approach to care requires an understanding of patients' health service needs, yet few studies have directly investigated the perceived health service needs of people with inflammatory arthritis. OBJECTIVES: To systematically identify the existing literature relating to patient perceived health service needs for inflammatory arthritis. METHODS: A systematic review of MEDLINE, EMBASE, CINAHL, and PsycINFO was conducted (1990-2016). Studies examining patients' perceived needs relating to health services for inflammatory arthritis were identified. Descriptive data regarding study design and methodology were extracted and risk of bias assessed. Findings were collated and categorized thematically. RESULTS: In total, 27 of 1405 (16 qualitative, 9 quantitative, and 2 mixed-methods) studies were relevant. The main areas of perceived need related to (1) Communication: consumers wanted clear, empathic communication, and to be involved with decision-making. (2) Characteristics of ongoing care: adequate consultation length with continuity and timely care were valued. (3) Factors influencing care-seeking included individual attitudes, disease severity, finances and family expectations. (4) Allied health and complementary and alternative medicines (CAM) were perceived as useful by many. The reporting of CAM use to doctors was variable, with several factors contributing to under-reporting. CONCLUSIONS: This review identified patients' perceived needs for better communication with their health providers, the heterogeneity of influences determining when care is sought and preferences regarding non-pharmacologic therapies. Aligning patients' perceived needs with evidence-based therapy for people with inflammatory arthritis will be important in optimizing patient outcomes. PMID- 29174793 TI - Footwear interventions for foot pain, function, impairment and disability for people with foot and ankle arthritis: A literature review. AB - OBJECTIVE: To conduct a literature review on the effectiveness of footwear on foot pain, function, impairment and disability for people with foot and ankle arthritis. METHODS: A search of the electronic databases Scopus, Medline, CINAHL, SportDiscus and the Cochrane Library was undertaken in September 2017. The key inclusion criteria were studies reporting on findings of footwear interventions for people with arthritis with foot pain, function, impairment and/or disability. The Quality Index Tool was used to assess the methodological quality of studies included in the qualitative synthesis. The methodological variation of the included studies was assessed to determine the suitability of meta-analysis and the grading of recommendations, assessment, development and evaluation (GRADE) system. Between and within group effect sizes were calculated using Cohen's d. RESULTS: 1440 studies were identified for screening with 11 studies included in the review. Mean (range) quality scores were 67% (39-96%). The majority of studies investigated rheumatoid arthritis (n = 7), but also included gout (n = 2), and 1st metatarsophalangeal joint osteoarthritis (n = 2). Meta-analysis and GRADE assessment were not deemed appropriated based on methodological variation. Footwear interventions included off-the-shelf footwear, therapeutic footwear and therapeutic footwear with foot orthoses. Key footwear characteristics included cushioning and a wide toe box for rheumatoid arthritis; cushioning, midsole stability and a rocker-sole for gout; and a rocker-sole for 1st metatarsophalangeal joint osteoarthritis. Between group effect sizes for outcomes ranged from 0.01 to 1.26. Footwear interventions were associated with reductions in foot pain, impairment and disability for people with rheumatoid arthritis. Between group differences were more likely to be observed in studies with shorter follow-up periods in people with rheumatoid arthritis (12 weeks). Footwear interventions improved foot pain, function and disability in people with gout and foot pain and function in 1st metatarsophalangeal joint osteoarthritis. Footwear interventions were associated with changes to plantar pressure in people with rheumatoid arthritis, gout and 1st metatarsophalangeal joint osteoarthritis and walking velocity in people with rheumatoid arthritis and gout. CONCLUSION: Footwear interventions are associated with reductions in foot pain, impairment and disability in people with rheumatoid arthritis, improvements to foot pain, function and disability in people with gout and improvements to foot pain and function in people with 1st metatarsophalangeal joint osteoarthritis. Footwear interventions have been shown to reduce plantar pressure rheumatoid arthritis, gout and 1st metatarsophalangeal joint osteoarthritis and improve walking velocity in rheumatoid arthritis and gout. PMID- 29174792 TI - A randomized, double-blind, placebo-controlled trial of infliximab in refractory polymyositis and dermatomyositis. AB - OBJECTIVE: To investigate in a pilot study the safety and efficacy of infliximab in patients with refractory dermatomyositis (DM) and polymyositis (PM). METHODS: A randomized, double-blind, placebo-controlled trial including subjects with active DM or PM. Participants had stable doses of immunosuppressive medication and prednisone (<=0.5mg/kg/day), and exhibited clinical signs of muscle weakness for at least 4 weeks prior to study entry. Participants received infusions of either placebo or infliximab 5mg/kg at 0, 2, 6, and 14 weeks in blinded manner. The primary outcome was a >=15% manual muscle strength (MMT) improvement at week 16 compared to week 0. The secondary outcome measures were improvement defined by the International Myositis Assessment and Clinical Studies Group (IMACS) criteria. At week 16, responders in each arm had the option of either continuing the same treatment or changing to the non-responder treatment for that study arm. Non-responders in the 5mg/kg infliximab arm were increased to infliximab 7.5mg/kg for weeks 22, 30, and 38. Non-responders in the placebo arm at week 16 received infliximab 5mg/kg at weeks 16, 18, 22, 30, and 38. Outcomes were reassessed at week 40. RESULTS: Twelve subjects completed the study to week 16. Six of the 12 subjects received infliximab treatment at the dose of 5mg/kg with only one subject meeting the responder criteria at that dose. Of the remaining five subjects on infliximab, three crossed over to the infliximab 7.5mg/kg dose. One of those three subjects responded. All six patients in the placebo arm crossed over to the 5mg/kg dosing regimen after week 16, and two of those responded to infliximab. CONCLUSIONS: Infliximab therapy for patients with refractory PM and DM was well tolerated and may benefit a subset of patients.

AB - OBJECTIVES: The aim of this study was to validate the use of survivin for preclinical recognition of rheumatoid arthritis (RA) among patients with unexplained arthralgia. METHODS: Serum levels of survivin and the arthritis specific autoantibodies RF and ACPA were measured in total of 5046 patients with musculoskeletal complains during 12 consecutive months in Gothenburg and in Umea. Among them, 303 arthralgia patients were identified and prospectively followed. RESULTS: After 48 months, 12.2% of the arthralgia patients developed RA. Most of RA cases had high serum survivin, which increased the relative risk for RA (RR = 5.90, p = 3 * 10-7). Combination of survivin with autoantibodies was present in only 4.6% of the arthralgia patients and increased further the risk of RA and shortened time to RA development. Presence of any single autoantibody in the survivin-negative patients was associated with a minor risk for RA and had RA free survival similar to the reference group. CONCLUSION: This study shows that measurement of survivin in serum improves estimation of RA risk and prospectively predicts RA development in patients with arthralgia. Survivin may indicate a phase preceding autoantibody production. PMID- 29174796 TI - Knowledge-based treatment planning and its potential role in the transition between treatment planning systems. AB - Commissioning a new treatment planning system (TPS) involves many time-consuming tasks. We investigated the role that knowledge-based planning (KBP) can play in aiding a clinic's transition to a new TPS. Sixty clinically treated prostate/prostate bed intensity-modulated radiation therapy (IMRT) plans were exported from an in-house TPS and were used to create a KBP model in a newly implemented commercial application. To determine the benefit that KBP may have in a TPS transition, the model was tested on 2 groups of patients. Group 1 consisted of the first 10 prostate/prostate bed patients treated in the commercial TPS after the transition from the in-house TPS. Group 2 consisted of 10 patients planned in the commercial TPS after 8 months of clinical use. The KBP-generated plan was compared with the clinically used plan in terms of plan quality (ability to meet planning objectives and overall dose metrics) and planning efficiency (time required to generate clinically acceptable plans). The KBP-generated plans provided a significantly improved target coverage (p = 0.01) compared with the clinically used plans for Group 1, but yielded plans of comparable target coverage to the clinically used plans for Group 2. For the organs at risk, the KBP-generated plans produced lower doses, on average, for every normal-tissue objective except for the maximum dose to 0.1 cc of rectum. The time needed for the KBP-generated plans ranged from 6 to 15 minutes compared to 30 to 150 and 15 to 60 minutes for manual planning in Groups 1 and 2, respectively. KBP is a promising tool to aid in the transition to a new TPS. Our study indicates that high-quality treatment plans could have been generated in the newly implemented TPS more efficiently compared with not using KBP. Even after 8 months of the clinical use, KBP still showed an increase in plan quality and planning efficiency compared with manual planning.

AB - Multiple myeloma is the leading indication of autologous hematopoietic cell transplantation (AHCT) worldwide. Hematopoietic progenitor cell mobilization (HPCM) is the first step of a successful AHCT. A minimum of 2*106 CD34+ cells/kg are needed for successful engraftment. Growth factors have been used both alone or in combination with chemotherapy for HPCM of patients with myeloma. Mobilization failures result in delays in AHCT and increased cost and resource utility. Strategies to mobilize progenitor cells were mainly chemotherapy and growth factor or growth factor-only mobilization until the advent of plerixafor. Plerixafor is successfully integrated into both growth factor-only and cyclophosphamide and growth factor mobilization strategies with significantly reducing the mobilization failure rate in myeloma patients. The best strategy to mobilize progenitor cells with the highest yield and lowest toxicity and cost in patients with multiple myeloma has not yet been determined. This review aims to summarize the current status of art mobilization in myeloma comparing the pros and cons of different mobilization strategies. PMID- 29174799 TI - The emerging functions and roles of circular RNAs in cancer. AB - Circular RNAs (circRNAs) are a class of single-stranded closed RNA molecules that undergo a specific backsplicing from pre-mRNA. With the application of high throughput sequencing and bioinformatics, circRNAs are found to be widely expressed across species. Some functionally characterized circRNAs have critical roles in gene regulation through various actions, including sponging microRNAs and proteins as well as regulating transcription and splicing. Moreover, most circRNAs are aberrantly expressed in different cancer types, and some of them have been reported to play important roles in the development and progression of cancer. Given the lack of a 5' cap structure and evidence of their ability to bind with ribosomes, circRNAs were generally considered as noncoding RNA. Notably, recent studies reported that endogenous circRNAs can be translated with a cap-independent manner, which redefines the functional roles of circRNA, further expanding the complexity of eukaryotic transcriptomes. This review aims to re-evaluate the functions and roles of circRNA from the cancer perspective. It discusses the current understanding of circRNA functions, the emerging roles of circRNA in cancer, and the challenges of future studies. PMID- 29174800 TI - ETS1 induction by the microenvironment promotes ovarian cancer metastasis through focal adhesion kinase. AB - Metastatic colonization involves paracrine/juxtacrine interactions with the microenvironment inducing an adaptive response through transcriptional regulation. However, the identities of transcription factors (TFs) induced by the metastatic microenvironment in ovarian cancer (OC) and their mechanism of action is poorly understood. Using an organotypic 3D culture model recapitulating the early events of metastasis, we identified ETS1 as the most upregulated member of the ETS family of TFs in metastasizing OC cells as they interacted with the microenvironment. ETS1 was regulated by p44/42 MAP kinase signaling activated in the OC cells interacting with mesothelial cells at the metastatic site. Human OC tumors had increased expression of ETS1, which predicted poor prognosis. ETS1 regulated OC metastasis both in vitro and in mouse xenografts. A combination of ChIP-seq and RNA-seq analysis and functional rescue experiments revealed FAK as the key transcriptional target and downstream effector of ETS1. Taken together, our results indicate that ETS1 is an essential transcription factor induced in OC cells by the microenvironment, which promotes metastatic colonization though the transcriptional upregulation of its target FAK. PMID- 29174801 TI - Dual targeting c-met and VEGFR2 in osteoblasts suppresses growth and osteolysis of prostate cancer bone metastasis. AB - Prostate cancer characteristically induces osteoblastic bone metastasis, for which no therapies are available. A dual kinase inhibitor of c-Met and VEGFR-2 (cabozantinib) was shown to reduce prostate cancer growth in bone, with evidence for suppressing osteoblastic activity. However, c-Met and VEGFR2 signaling in osteoblasts in the context of bone metastasis remain unclear. Here we show using cultured osteoblasts that hepatocyte growth factor (HGF) and VEGF-A increased receptor activator of NFkappaB ligand (RANKL) and M-CSF, two essential factors for osteoclastogenesis. Insulin-like growth factor-1 (IGF1) also increased RANKL and M-CSF via c-Met transactivation. The conditioned media from IGF1-, HGF-, or VEGFA-treated osteoblasts promoted osteoclastogenesis that was reversed by inhibiting c-Met and/or VEGFR2 in osteoblasts. In vivo experiments used cabozantinib-resistant prostate cancer cells (PC-3 and C4-2B) to test the effects of c-Met/VEGFR2 inhibition specifically in osteoblasts. Cabozantinib (60 mg/kg, 3 weeks) suppressed tumor growth in bone and reduced expression of RANKL and M-CSF and subsequent tumor-induced osteolysis. Collectively, inhibition of c-Met and VEGFR2 in osteoblasts reduced RANKL and M-CSF expression, and associated with reduction of tumor-induced osteolysis, suggesting that c-Met and VEGFR2 are promising therapeutic targets in bone metastasis. PMID- 29174802 TI - Targeting signaling pathways in multiple myeloma: Pathogenesis and implication for treatments. AB - Multiple myeloma (MM), which is characterized by osteolytic bone lesions, anemia, hypercalcemia, and renal failure, accounts for approximately 10% of all hematologic malignancies. Although the therapeutic landscape of MM has evolved spectacularly over the past decades with 5-year median survival over 50%, most of these patients relapse eventually. The widely recognized therapeutic approaches include chemotherapy, radiation, stem cell transplant, and monoclonal antibody therapy. Former studies have implied that the proliferation, survival, migration and drug resistance of MM cells are in association with the activation of several signaling pathways. In this review, we intended to focus on the major signaling pathways such as PI3K/Akt/mTOR, Ras/Raf/MEK/MAPK, JAK/STAT, NF-kappaB, Wnt/beta catenin, and RANK/RANKL/OPG, that contribute to the pathogenesis of the MM and the therapeutic approaches developed to target them. PMID- 29174803 TI - HBXIP-elevated methyltransferase METTL3 promotes the progression of breast cancer via inhibiting tumor suppressor let-7g. AB - Methyltransferase-like 3 (METTL3) is involved in RNA metabolism through N6 methyladenosine (m6A) modification. However, whether METTL3 participates in the progression of breast cancer is unclear. Aberrant expression of Mammalian hepatitis B X-interacting protein (HBXIP) drives the aggressiveness of breast cancer. Here, we are interested in the potential links between HBXIP and METTL3 in breast cancer. We showed that the expression of METTL3 was positively related to that of HBXIP in clinical breast cancer tissues. Moreover, HBXIP could up regulate METTL3 in breast cancer cells. Mechanistically, HBXIP modulated METTL3 by inhibiting miRNA let-7g, which down-regulated the expression of METTL3 by targeting its 3'UTR. Strikingly, we found that METTL3 promoted the expression of HBXIP through m6A modification. Furthermore, overexpressed HBXIP could rescue the inhibited-proliferation and enhanced-apoptosis induced by silencing of METTL3 in breast cancer cells. Thus, we conclude that HBXIP up-regulates METTL3 by suppressing let-7g, in which METTL3 increased HBXIP expression forming a positive feedback loop of HBXIP/let-7g/METTL3/HBXIP, leading to accelerated cell proliferation in breast cancer. Our finding provides new insights into the mechanism of the mutual regulation between HBXIP and METTL3 in the progression of breast cancer. PMID- 29174804 TI - Organoids: An intermediate modeling platform in precision oncology. AB - Cancer harbors variable heterogeneity and plasticity. Thus far, our comprehension is greatly based on cell lines, organoids, and patient-derived tumor xenografts (PDTXs). Organoids are a three-dimensional in vitro culture platform constructed from self-organizing stem cells. They can almost accurately recapitulate tumor heterogeneity and microenvironment "in a dish," which surpass established cell lines and are not as expensive and time-consuming as PDTXs. As an intermediate model, tumor organoids are also used to study the fundamental issues of tumorigenesis and metastasis. They are specifically applied for drug testing and stored as "living biobanks." In this review, we highlight the translational applications of organoid technologies in tumor research and precision medicine, discuss the advantages and limitations compared with other mentioned methods, and provide our outlook on its future.

PMID- 29174806 TI - Is routine holistic assessment with a prompt list feasible during consultations after treatment for oral cancer? AB - The head and neck cancer Patient Concerns Inventory (PCI-HN) is a holistic, self reported list of items that can help patients to disclose their needs and concerns during routine follow-up consultations. The aim of this study was to report how often it was used during the first three years of follow up after treatment for oral cancer, and the range of issues that were raised. The sample comprised consecutive patients treated over a three-year period with curative intent. All clinic attendances were reviewed until October 2015 or until patients had a recurrence, a subsequent primary, metastases, or were discharged home or to follow up at a peripheral hospital, or started palliative care. We identified 92 patients and data were available for 88 of them. The median (IQR) age at the time of treatment was 65 (57-76) years, and 48 (55%) were men. Reviews alternated between the surgeon and oncologist, and typically there were 4.4 surgical reviews in year one, 2.8 in year two, and 1.6 in year three. The inventory was completed 157 times; at least once by 71% (55/77) during year one, 57% (29/51) during year two, and 37% (13/35) during year three. Of those who completed none, nearly half (7/17) died within 12 months, and another six were over 80 years of age. In conclusion, the diversity of concerns raised by patients highlights the need for holistic assessment during follow up, and integration of the inventory into routine consultations will mean that we can repeat it. PMID- 29174807 TI - Impact of hydration and nutrition on personal performance in the clinical workplace. AB - As clinicians we sometimes fail to look after ourselves at work. We often do not drink enough during the day or miss lunch breaks while caring for patients, and this can be particularly evident during an all-day operating list when procedures are long and complex. Some operating theatre staff do not even eat breakfast regularly. Inadequate intake of fluids or nutrition can impair performance, lead to tiredness and headaches, and may compromise both our own health and the care we provide to patients. Other high-risk organisations, including aviation, have recognised that employees must look after themselves if they are to optimise their performance. In this review, we discuss the importance of adequate hydration and nutrition at work to raise awareness that this is essential if we are to provide the best care for our patients.

AB - Aiming to explore novel anaplastic lymphoma kinase (ALK) and proto-oncogene tyrosine-protein kinase ROS (ROS1) dual inhibitors to overcome crizotinib resistant mutants, two series of 2,4-diarylaminopyrimidine (DAAP) analogues bearing thiazole or 1,2,3-triazole moieties were designed and synthesized based upon the cocrystal structure of ceritinib with ALKWT (PDB 4MKC) as well as the binding model of ceritinib with ALKG1202R. The cellular and enzymatic assays validated 34c (WY-135) as a promising ALK (IC50 = 1.4 nM) and ROS1 (IC50 = 1.1 nM) dual inhibitor superior to crizotinib and ceritinib. 34c showed significantly inhibitory activities on ALK-dependent cell lines KARPAS299 (IC50 = 21 nM) and H2228 (IC50 = 95 nM) as well as ROS1-positive cell line HCC78 (IC50 = 40 nM). In particular, 34c was potent against a variety of frequently observed crizotinib resistant mutants, particularly the L1196M mutant (IC50 = 3.1 nM) identified as the "gatekeeper" mutation and the G1202R mutant (IC50 = 8.7 nM) which conferred resistance to all clinical stage ALK inhibitors. Furthermore, 34c was capable of inducing cell apoptosis and strongly inhibiting cellular ALK and ROS1 activity. In addition, the binding models of 34c with ALKWT, ALKL1196M and ALKG1202R provided structural bases for SARs observations. PMID- 29174810 TI - Design, synthesis, and biological evaluation of new 1,2,3-triazolo-2'-deoxy-2' fluoro- 4'-azido nucleoside derivatives as potent anti-HBV agents. AB - Novel drugs are urgently needed to combat hepatitis B virus (HBV) infection due to drug-resistant virus. In this paper, a series of novel 4-monosubstituted 2' deoxy-2'-beta-fluoro-4'-azido-beta-d-arabinofuranosyl 1,2,3-triazole nucleoside analogues (1a-g) were designed, synthesized and screened for in vitro anti-HBV activity. At 5.0 MUM in the cellular model, all the synthetic compounds display activities comparable to that of the positive control, lamivudine at 20 MUM. Of the compounds tested, the amide-substituted analogue (1a) shows the most promising anti-HBV activity and low cytotoxicity in the cell model. In particular, it retains excellent activity against lamivudine-resistant HBV mutants. In duck HBV (DHBV)-infected duck models, both the serum and liver DHBV DNA levels (67.4% and 53.3%, respectively) were reduced markedly by the treatment with 1a. Analysis of the structure of HBV polymer/1a-triphosphate (1a-TP) complex shows that 1a-TP is stabilized by specific van der Waals interactions with the enzyme residues arising from 4-amino-1,2,3-triazole and the 4'-azido group.

The scaffolds with longer spacer length (n = 6, 8) between two pharmacophores and a halogen substituent on the phthalimide ring displayed good antiplasmodial activity. Compound 5w, with an optimum combination of hexyl chain as spacer along with a tetra-bromophthalimide ring proved to be most potent and non-cytotoxic among the series exhibiting an IC50 value of 0.10 MUM. PMID- 29174812 TI - Amino acid and peptide prodrugs of diphenylpropanones positive allosteric modulators of alpha7 nicotinic receptors with analgesic activity. AB - alpha7 Nicotinic acetylcholine receptors (nAChRs) are ion channels implicated in a number of CNS pathological processes, including pain and psychiatric, cognitive and inflammatory diseases. Comparing with orthosteric agonism, positive allosteric modulation of these channels constitutes an interesting approach to achieve selectivity versus other nicotinic receptors. We have recently described new chalcones and 1,3-diphenylpropanones as positive allosteric modulators (PAMs) of alpha7 nAChRs, which proved to have good analgesic activities but poor pharmacokinetic properties. Here we report the preparation of amino acid and peptide derivatives as prodrugs of these modulators with the aim of improving their in vivo biological activity. While the valine derivative showed very short half life in aqueous solutions to be considered a prodrug, Val-Val and Val-Pro Val are suitable precursors of the parent 1,3-diphenylpropanones, via chemical and enzymatic transformation, respectively. Compounds 19 (Val-Val) and 21 (Val Pro-Val), prodrugs of the 2',5',4-trihydroxy-1,3-diphenylpropan-1-one 3, showed significant antinociceptive activity in in vivo assays. The best compound, 21, displayed a better profile in the analgesia test than its parent compound 3, exhibiting about the same potency but long-lasting effects. PMID- 29174813 TI - Synthesis and biological evaluation of sulfur-containing shikonin oxime derivatives as potential antineoplastic agents. AB - As a continuation of our research on developing potent and potentially safe antineoplastic agents, a set of forty five sulfur-containing shikonin oxime derivatives were synthesized and evaluated for their in vitro cytotoxic activity against human colon cancer (HCT-15), gastric carcinoma (MGC-803), liver (Bel7402), breast (MCF-7) cancer cells and human skin fibroblast (HSF) cells. All the synthesized compounds exhibited potent cytotoxic activity selectively towards HCT-15 cells and did not display apparent toxicity to the normal HSF cells, some of which were more or comparatively effective to the parent compound against HCT 15, MGC-803 and Bel7402 cells. The most active agent 9m displayed high potency against human cancer cells with IC50 ranging from 0.27 +/- 0.02 to 9.23 +/- 0.12 MUM. The structure-activity relationships (SARs) studies suggested that the nature of substituent group in the side chain is important for antitumor potency in vitro. Additionally, nitric oxide release studies revealed that the amount of nitric oxide generated from these oxime derivatives was relatively low. Furthermore, cellular mechanism investigations indicated that compound 9m could arrest cell cycle at G1 phase and induce a strong apoptotic response in HCT-15 cells. Moreover, western blot studies revealed that compound 9m induced apoptosis through the down-regulation of Bcl-2 and up-regulation of Bax, caspase 3 and 9. For all these reasons, compound 9m hold promising potential as antineoplastic agent.

AB - With the aim of discovering potential and selective inhibitors targeting ROS1 kinase, we rationally designed, synthesized and evaluated two series of novel 2 amino-pyridine derivatives with 1-phenylethoxy at C-3 and C-4 position. The enzymic assays results indicated that six of the new compounds 13b-13d and 14a 14c showed remarkably higher inhibitory activities against ROS1 kinase. The most promising compounds, 13d and 14c displayed the most desired ROS1 inhibitory activity with IC50 values of 440 nM and 370 nM respectively. Furthermore, 13d and 14c displayed ROS1 inhibitory selectivity of about 7-fold and 12-fold, relative to that of ALK sharing about 49% amino acid sequence homology in the kinase domains. They also showed good anti-proliferative effects against ROS1-addicted HCC78 cell lines with the IC50 values of 8.1 MUM and 65.3 MUM, respectively. Moreover, molecular docking and molecular dynamics simulation studies disclosed that compound 14c and 13d shared similar binding poses with Crizotinib except the selective binding site of ROS1. It also gave a probable molecular explanation for their activity and selectivity, which the methoxyl group in benzene ring was the crucial to the selectivity to ROS1 versus ALK.

AB - With a goal of identifying potent topoisomerase (topo) inhibitor, the C4-aromatic ring of the anticancer agent, 3,4-diarylisoquinolone, was strategically shifted to design 1,3-diarylisoquinoline. Twenty-two target compounds were synthesized in three simple and efficient steps. The 1,3-diarylisoquinolines exhibited potent anti-proliferative effects on cancer cells but few compounds spared non-cancerous cells. Inhibition of topo I/IIalpha-mediated DNA relaxation by several derivatives was greater than that by camptothecin (CPT)/etoposide even at low concentration (20 MUM). In addition, these compounds had little or no effect on polymerization of tubulin. A series of biological evaluations performed with the most potent derivative 4cc revealed that the compound is a non-intercalative topo I catalytic inhibitor interacting with free topo I. Collectively, the potent cytotoxic effect on cancer cells including the drug resistance ones, absence of lethal effect on normal cells, and different mechanism of action than topo I poisons suggest that the 1,3-diarylisoquinolines might be a promising class of anticancer agents worthy of further pursuit. PMID- 29174816 TI - Synthesis and biological evaluation of curcumin inspired imidazo[1,2-a]pyridine analogues as tubulin polymerization inhibitors. AB - With an aim to develop new curcumin inspired analogues as potent anticancer agents, we synthesized a series of (1E,4E)-1-phenyl-5-(3-phenylimidazo[1,2 a]pyridin-2-yl)penta-1,4-dien-3-ones (12a-t) as tubulin polymerization inhibitors. An initial screening was carried out to evaluate their cytotoxic potential on a panel of six cancer cell lines namely, cervical (HeLa), gastric (HGC-27), lung (NCI-H460), prostate (DU-145 and PC-3) and breast (4T1), using MTT assay. Among the compounds tested, compounds 12e, 12r and 12t showed potent growth inhibition and 12t {(1E,4E)-1-(3-(3,4-difluorophenyl)imidazo[1,2-a]pyridin 2-yl)-5-(2,4,6-trimethoxyphenyl)penta-1,4-dien-3-one} being the most active member of the series inhibited the growth of all the tested cell lines with IC50 values varying from 1.7 - 2.97 MUM. Moreover, 12t showed promising cytotoxicity on PC-3, HGC-27 and HeLa cell lines with IC50 values of 2.11 +/- 0.27 MUM, 2.21 +/- 0.25 MUM and 2.53 +/- 0.01 MUM respectively. The results from aqueous solubility test showed that compounds 12e and 12t have 1.7 and 2.8 times more aqueous solubility than curcumin. Interestingly, the most active compound 12t was found to be nearly 2 times more selective on PC-3 cells as well as safe on normal human prostate (RWPE-1) cells. In addition, compound 12t efficiently inhibited tubulin polymerization with IC50 value of 8.44 +/- 0.13 MUM and molecular modelling studies disclosed that 12t binds at the colchicine binding site of the tubulin. Cell cycle analysis revealed that 12t arrests PC-3 cells in G2/M phase in a dose dependant manner. Further, treatment of PC-3 cells with 12t showed typical apoptotic morphology, also led to the impairment of mitochondrial membrane potential (DPsim) and increased levels of reactive oxygen species (ROS). Altogether, the results from acridine orange/ethidium bromide (AO-EB) and DAPI staining studies, annexin V-FITC/propidium iodide staining assay, analysis of mitochondrial membrane potential (DPsim) and reactive oxygen species (ROS) levels undoubtedly demonstrated the induction of apoptosis in PC-3 cells by compound 12t.

AB - INTRODUCTION: The prevalence of bladder cancer (BC) in neurological patients seems to be similar to that of the general population. However, they are more aggressive with a higher rate of muscle-invasive forms and squamous cells carcinomas. The aim of the current study was to report etiologies, management and outcomes of BC in neurological population. MATERIAL AND METHOD: Were enrolled all neurological patients with a BC diagnosed between 2004 and 2017. The following data were retrospectively reported: age, gender, duration of the disease, mode of discovery, histological type, treatment and outcomes. RESULTS: In total, 27 patients were included: 11 spinal cord injuries, 7 Parkinson's disease, 5 multiple sclerosis, 3 head trauma, 3 brain strokes, 2 cerebral palsies and 1 spina bifida. The histological subtypes were as follows: 22 transitional cells carcinomas, 4 squamous cell carcinomas (SCC), one mucinous adenocarcinoma, one sarcomatoid and one neuroendocrine with 19 high-grade tumors and 15 muscle invasive bladder cancer. Seven patients (26%) were diagnosed before 15 years history of neurogenic bladder. The mean follow-up was 14 months (1-210 months). Eight deaths were observed, with 5 related to bladder cancer. In our study, smoking habits, voiding mode, lithiasis or infection histories were not related with a more aggressive pattern, such as SCC. CONCLUSION: The high rate of muscle invasive bladder cancer and aggressive patterns justify neuro-urological follow up, even before 15 years of neurogenic bladder. LEVEL OF EVIDENCE: 4. PMID- 29174818 TI - Inhibition of advanced glycation endproduct (AGE) rescues against streptozotocin induced diabetic cardiomyopathy: Role of autophagy and ER stress. AB - Diabetes mellitus leads to oxidative stress and contractile dysfunction in the heart. Although several rationales have been speculated, the precise mechanism behind diabetic cardiomyopathy remains elusive. This study was designed to assess the role of inhibition of advanced glycation endproducts (AGE) in streptozotocin (STZ)-induced diabetic cardiac dysfunction. Cardiac contractile function was assessed in normal C57BL/6 and STZ (200mg/kg, single injection and maintained for 2 wks)-induced diabetic mice treated with or without the AGE inhibitor aminoguanidine (50mg/kg/d in drinking water) for 2 weeks using echocardiography and IonOptix MyoCam techniques. Diabetes compromised cardiac contractile function shown as reduced fractional shortening and ejection fraction, enlarged left ventricular end systolic/diastolic diameters, decreased peak shortening, maximal velocity of shortening/relengthening, prolonged shortening and relengthening duration as well as impaired intracellular Ca2+ homeostasis, the effects of which were alleviated or reversed by aminoguanidine treatment. Diabetes also inhibited autophagy, increased ER stress and phosphorylation of pro-hypertrophic signaling molecules Akt and mTOR, the effect of which was reversed by aminoguanidine. In vitro study revealed that methylglyoxal-derived AGE (MG-AGE) incubation in isolated cardiomyocytes promoted oxidation of sarco(endo)plasmic reticulum Ca2+ ATPase (SERCA2a) and production of superoxide, the effects of which were negated by the autophagy inducer rapamycin, the ER stress chaperone TUDCA or the antioxidant N-acetylcysteine. Taken together, these data revealed that inhibition of AGE formation rescues against experimental diabetes-induced cardiac remodeling and contractile dysfunction possible through regulation of autophagy and ER stress. PMID- 29174820 TI - Effect of rat parental morphine exposure on passive avoidance memory and morphine conditioned place preference in male offspring. AB - Drug addiction is a chronic disorder resulted from complex interaction of genetic, environmental, and developmental factors. Epigenetic mechanisms play an important role in the development and maintenance of addiction and also memory formation in the brain. We have examined passive avoidance memory and morphine conditioned place preference (CPP) in the offspring of male and/or female rats with a history of adulthood morphine consumption. Adult male and female animals received chronic oral morphine for 21days and then were maintained drug free for 10days. After that, they were let to mate with either an abstinent or control rat. Male offspring's memory was evaluated by step through test. Besides, rewarding effects of morphine were checked with CCP paradigm. Offspring of abstinent animals showed significant memory impairment compared to the control group which was more prominent in the offspring of abstinent females. Conditioning results showed that administration of a high dose of morphine (10mg/kg) that could significantly induce CPP in control rats, was not able to induce similar results in the offspring of morphine abstinent parents; and CPP was much more prominent when it was induced in the offspring of morphine exposed females compared to the progeny of morphine exposed males. It is concluded that parental morphine consumption in adulthood even before mating has destructive effects on memory state of the male offspring and also leads to tolerance to the rewarding effects of morphine. These effects are greater when the morphine consumer parent is the female one. PMID- 29174821 TI - The impact of care management information technology model on quality of care after percutaneous coronary intervention: "Bridging the Divides". AB - BACKGROUND: Reducing readmissions and improving metrics of care are a national priority. Supplementing traditional care with care management may improve outcomes. The Bridges program was an initial evaluation of a care management platform (CareLinkHub), supported by information technology (IT) developed to improve the quality and transition of care from hospital to home after percutaneous coronary intervention (PCI) and reduce readmissions. METHODS: CareLink is comprised of care managers, patient navigators, pharmacists and physicians. Information to guide care management is guided by a middleware layer to gather information, PLR (ColdLight Solutions, LLC) and presented to CareLink staff on a care management platform, AerialTM (Medecision). An additional analytic engine [NeuronTM (ColdLight Solutions, LLC)] helps, evaluates and guide care. RESULTS: The "Bridges" program enrolled a total of 2054 PCI patients with 2835 admission from April, 1st 2013 through March 1st, 2015. The data of the program was compared with those of 3691 PCI patients with 4414 admissions in the 3years prior to the program. No impact was seen with respect to inpatient and observation readmission, or emergency department visits. Similarly no change was noticed in LDL control. There was minimal improvement in BP control and only in the CTM-3 and SAQ-7 physical limitation scores in the patients' reported outcomes. Patient follow-up with physicians within 1week of discharge improved during the Bridges years. CONCLUSIONS: The CareLink hub platform was successfully implemented. Little or no impact on outcome metrics was seen in the short follow up time. The Bridges program suggests that population health management must be a long-term goal, improving preventive care in the community. PMID- 29174822 TI - Acute procedural outcomes of orbital atherectomy for the treatment of iliac artery disease: Sub-analysis of the CONFIRM registries. AB - Endovascular intervention is an appealing revascularization strategy for iliac artery disease. Atherectomy of the iliac artery is uncommon due to the risk of life-threatening perforation but may be necessary if the iliac lesion is heavily calcified, preventing stent delivery or optimal expansion. We assessed the feasibility and safety of orbital atherectomy for the treatment of iliac artery disease. Demographic data, lesion characteristics, and procedure outcomes for the CONFIRM patients with at least one iliac artery lesion treated with orbital atherectomy (n=62 patients; n=68 lesions) were compared to patients with at least one superficial femoral artery (SFA) lesion treated with orbital atherectomy (n=1570 patients; n=1809 lesions). The procedural complication rate, defined as the composite of flow limiting dissection, perforation, slow flow, vessel closure, spasm, embolism, or thrombosis, was compared in iliac lesions versus SFA lesions. The iliac artery group had more patients with diabetes, shorter lesions, and more severely calcified lesions. The orbital atherectomy run time was significantly shorter in the iliac artery group. Additionally, in the iliac group there was one reported perforation and one reported vessel closure; the rates of slow flow, spasm, embolism, thrombus, and flow limiting dissection were 0%. The overall procedural complication rate was significantly lower in the iliac group (2.9% vs. 11.2%, p=0.03). Orbital atherectomy of the iliac artery is feasible with few reported angiographic complications and compared favorably with the SFA group. Orbital atherectomy may be considered to facilitate the delivery and expansion of a balloon or stent if the iliac artery is calcified. PMID- 29174819 TI - Considering sex differences in the cognitive controls of feeding. AB - Women are disproportionately affected by obesity, and obesity increases women's risk of developing dementia more so than men. Remarkably little is known about how females make decisions about when and how much to eat. Research in animal models with males supports a framework in which previous experiences with external food cues and internal physiological energy states, and the ability to retrieve memories of the consequences of eating, determines subsequent food intake. Additional evidence indicates that consumption of a high-fat, high-sugar diet interferes with hippocampal-dependent mnemonic processes that operate to suppress eating, such as in situations of satiety. Recent findings also indicate that weakening this form of hippocampal-dependent inhibitory control may also extend to other forms of learning and memory, perpetuating a vicious cycle of increased Western diet intake, hippocampal dysfunction, and further impairments in the suppression of appetitive behavior that may ultimately disrupt other types of memorial interference resolution. How these basic learning and memory processes operate in females to guide food intake has received little attention. Ovarian hormones appear to protect females from obesity and metabolic impairments, as well as modulate learning and memory processes, but little is known about how these hormones modulate learned appetitive behavior. Even less is known about how a sex-specific environmental factor - widespread hormonal contraceptive use - affects associative learning and the regulation of food intake. Extending learned models of food intake to females will require considerably investigation at many levels (e.g., reproductive status, hormonal compound, parity). This work could yield critical insights into the etiology of obesity, and its concomitant cognitive impairment, for both sexes. PMID- 29174823 TI - Modified balloon aortic valvuloplasty in fragile symptomatic patients unsuitable for both surgical and percutaneous valve replacement. AB - BACKGROUND: Balloon Aortic valvuloplasty (BAV) is considered as a bridge therapy to percutaneous valve implantation or a palliative treatment in patients with aortic valve stenosis (AVS). Potential risk of complications, in particular in fragile patients, is still not negligible. AIM: To describe the technique and outcomes of modified BAV in fragile symptomatic patients unsuitable for other treatments using no-pacing and minimally invasive approach. METHODS: Symptomatic fragile patients with severe aortic valve stenosis judged unsuitable by the heart team for surgical or percutaneous valve implantation from 1 September 2013 to 1 September 2017 were offered modified BAV. Simplified procedural protocol included a 4F right radial artery access for gradient check, a 8F compatible undersized balloons, two partial inflations-trial before a full inflation with no-pace maker back-up, final pressure gradient recording and aortography. RESULTS: Thirty-four symptomatic fragile patients (mean age 80.9+/-4.9, range 73 to 91years, 100% Katz >6, mean Euroscore I 30.0+/-11.7%) underwent modified BAV in the last 5years with immediate success in all (100%). Mean aortic valve area increased from 0.58+/ 0.2cm2 to 1.1+/-0.2cm2 (p<0.01) whereas mean peak gradient decreased from 75.6+/ 11.3 to 35.8+/-11.2mmHg (p<0.01). Procedural complications were 14.7%. Thirty-day mortality was 11.8%. On a mean follow up of 38.4+/-4.6months four patients successfully repeated the procedure, while global mortality was 23.5% (8 patients). The other 22 patients maintained a NYHA class of 2.1+/-0.7. CONCLUSIONS: No-pacing minimally invasive BAV seems to have acceptable outcomes in patients with severe AVS and no other treatment options. PMID- 29174824 TI - Intraprocedural invasive hemodynamic parameters as predictors of short- and long term outcomes in patients undergoing transcatheter aortic valve replacement. AB - OBJECTIVE: Evaluation of invasive hemodynamic parameters as prognostic markers of mortality in patients undergoing TAVR. BACKGROUND: The value of invasive intraprocedural hemodynamic evaluation of patients undergoing transcatheter aortic valve replacement is unclear. METHODS: Consecutive patients who underwent transfemoral TAVR and had complete prospectively collected intraprocedural invasive hemodynamic parameters were retrospectively analyzed. Patients with alternative access, planned general anesthesia, or baseline >=moderate Tricuspid Regurgitation were excluded. Pre- and post-valve implant parameters included heart rate, systolic and diastolic blood pressures, cardiac output and index, pulmonary arterial systolic and diastolic pressures, transaortic pressure gradient and right atrial pressure. The primary end points were the association of the intraprocedural hemodynamic changes with all-cause mortality at 30days and 1year. Extensive Receiver Operating Characteristic analyses yielded dichotomized threshold of hemodynamic values in association with the binary outcome of mortality. RESULTS: A total of 312 patients (52% male, mean age 83years) were evaluated. A significant association with 30-day and 1-year mortality was found between intraprocedural post-valve implant cardiac index <1.9 vs. >=1.9L/min/m2 (Log-ranked p=0.0286 and p=0.0432, respectively). Four subgroups with pre- and post-valve implant CI changes (L/min/m2) were compared: [1] pre<1.9, stable_post<1.9; [2] pre<1.9, improved_post>=1.9; [3] pre>=1.9, stable_post>=1.9; and [4] pre>=1.9, worsened_post<1.9. Group 1 (lower CI with no post-valve improvement) had the worst survival, and Group 3 (higher CI and stable post valve) had the best survival at 1-year follow-up (Log-ranked p=0.0089). CONCLUSIONS: In patients with severe aortic stenosis undergoing TAVR, invasive monitoring can assess for hemodynamic prognostic markers of survival. PMID- 29174825 TI - When intravascular ultrasound becomes indispensable in percutaneous coronary intervention of a chronic total occlusion. AB - Percutaneous coronary intervention of chronic total occlusion is a particular interventional area which requires high level of operator's experience and the support of additional tools based on intracoronary image such as intravascular ultrasound in many cases to clarify difficulties during procedures and to increase success rate. Implantation of long stents in many cases, the presence of stump ambiguity, and the use of specific techniques in this kind of interventions, such as reverse controlled antegrade and retrograde subintimal tracking (CART) and reverse CART make necessary in many cases the use of intravascular ultrasound for a better understanding of the situation, for reducing eventual complications and increasing procedural success rate. We made a review of literature related to most challenging situations in which the use of intravascular ultrasound during chronic total occlusion percutaneous coronary intervention becomes rather indispensable to safely continue and finish the procedure. Besides, two complex percutaneous coronary interventions of chronic total occlusion with unfavourable anatomic features in which intravascular ultrasound was crucial for the procedural success are presented in this manuscript along with support of the literature. PMID- 29174826 TI - Predicting of ultrafiltration performances by advanced data analysis. AB - In order to optimize drinking water production operation, membrane users can use several analytical tools that help membrane fouling prediction and alleviate fouling by a proper feed water resource selection. However, during strong fouling event, membrane decision-makers still face short-term deadline to decide between different options (e.g. optimization of pretreatment or change in feed water quality). Hence, statistical approach might help to better select the most relevant analytical parameter related to fouling potential of a specific resource in order to speed-up decision taking. In this study, the physical and chemical properties and the filtration performances (at lab-scale) of five ground water resources, selected as potential resources of a large drinking production site of Paris (France), was evaluated through one year. Principal component analysis emphasizes the strong link between waters' organic matrix and fouling propensity. Cluster analysis of filtration performances allowed classifying the water samples into three groups exhibiting strong, low and intermediate fouling. Finally, multiple linear regressions performed on all collected data indicated that strong fouling events were related to a combined increase of carbon content and protein like-substances while intermediate fouling might only be anticipated by an increase of fluorescence signal associated to protein like-substances. This study demonstrates that advanced data analysis might be a powerful tool to better manage water resources selection used for drinking water production and to forecast filtration performances in a context of water quality degradation. PMID- 29174827 TI - Transport of iron nanoparticles through natural discrete fractures. AB - The transport of nano scale iron particles (NIP) in fractures is of concern for remediation of both fractured aquifers and porous aquifers when hydro-fracking and flow in preferential pathways takes place. In this study the transport of various NIP in a natural discrete fractured chalk core was investigated and their mass recoveries calculated. Four different types of NIP were tested and characterized in two ionic strength (IS) solutions at a particle concentration of 100-200 mg/l. The effect of IS, stability (sedimentation rate), particle size, solution viscosity and stabilizer were studied. NIP stability ranged from 1 to 100% following 120 min of stability tests and recoveries ranged from about 6 to 69%. The stabilizer type and concentration were shown to have significant role in NIP recoveries, especially at increased IS. It was evident that gravitational stability is the most crucial factor dominating transport of NIP. Accordingly, stability tests were shown to be a reliable indicator of NIP mobility. The high recoveries of some NIP tested, combined with the lack of clogging effect illustrates the enhanced mobility of NIP in fractures. The wide range of recoveries indicates NIP transport manipulation potential in such media. We therefore suggest that application of NIP in contaminated fractures has considerable potential as a remediation measure. In order to achieve NIP distribution in the aquifer while avoiding leakage to the environment, NIP stabilizer concentration should be adjusted according to the site-specific hydrogeochemical properties of the contaminated media. PMID- 29174828 TI - Wet biowaste digestion: ADM1 model improvement by implementation of known genera and activity of propionate oxidizing bacteria. AB - Anaerobic digestion of biowaste not only reduces environmental burden but also plays an important role for sustainable energy supply. For process optimization simulation based on the Anaerobic Digestion Model No. 1 (ADM1) is commonly used. The ADM1 was extended to include the known three genera of propionate oxidizing bacteria (POB) and the two routes of propionate degradation (methyl-malonyl CoA and C6-dismutation pathway). Kinetic parameters for anaerobic propionate oxidation by single strains of the three propionate oxidizing genera were determined from defined tri-cultures of the POB with hydrogenotrophic and acetotrophic methanogens and implemented into ADM1. The such improved model ADM1xpro was evaluated with operational data from a full scale wet biowaste digestion plant. Predicted amounts of biogas and composition with ADM1xpro (2201 m3 d-1, 68.1 % CH4 and 31.9 % CO2) correlated well with full-scale process data (2171 m3 d-1, 67.5 % CH4 and 31.9 % CO2). PMID- 29174829 TI - Intrinsic tradeoff between kinetic and energetic efficiencies in membrane capacitive deionization. AB - Significant progress has been made over recent years in capacitive deionization (CDI) to develop novel system configurations, predictive theoretical models, and high-performance electrode materials. To bring CDI to large scale practical applications, it is important to quantitatively understand the intrinsic tradeoff between kinetic and energetic efficiencies, or the relationship between energy consumption and the mass transfer rate. In this study, we employed both experimental and modeling approaches to systematically investigate the tradeoff between kinetic and energetic efficiencies in membrane CDI (MCDI). Specifically, we assessed the relationship between the average salt adsorption rate and specific energy consumptions from MCDI experiments with different applied current densities but a constant effluent salinity. We investigated the impacts of feed salinity, diluted water salinity, diluted water volume per charging cycle, and electrode materials on the kinetics-energetics tradeoff. We also demonstrate how this tradeoff can be employed to optimize the design and operation of CDI systems and compare the performance of different electrode materials and CDI systems. PMID- 29174830 TI - Influence of Shift Duration on Cognitive Performance of Emergency Physicians: A Prospective Cross-Sectional Study. AB - STUDY OBJECTIVE: The relationship between tiredness and medical errors is now commonly accepted. The main objective of this study is to evaluate the cognitive performance of emergency physicians after a night shift of 14 hours (H14) and after a work shift of 24 hours (H24) and to compare it with tests performed after a rest night at home (H0). METHODS: Forty emergency physicians (19 staff physicians and 21 residents) were randomly evaluated at H0, H14, and H24. Four cognitive abilities (processing speed, working memory capacity, perceptual reasoning, and cognitive flexibility) were tested according to the Wechsler Adult Intelligence Scale and the Wisconsin Card Sorting Test. RESULTS: No cognitive ability was significantly altered after H14 compared with H0. Three of 4 cognitive abilities were impaired at H24 compared with H0: processing speed (11.2 [SD 2.7] versus 12.4 [SD 3.2]; mean difference=-1.2 [95% confidence interval -1.9 to -0.5]), working memory capacity (10.1 [SD 2.9] versus 11.6 [SD 3.0]; mean difference=-1.5 [95% confidence interval -2.2 to -0.8]), and perceptual reasoning (8.4 [SD 2.7] versus 10.6 [SD 2.8]; mean difference=-2.2 [95% confidence interval -3.4 to -1.0]). Cognitive abilities were not different between residents and staff physicians (except for perceptual reasoning) and were not affected by the amount of sleep during the night shift. CONCLUSION: The cognitive abilities of emergency physicians were significantly altered after a 24-hour shift, whereas they were not significantly different from the rested condition after a 14-hour night shift. Limiting 24-hour shift work for emergency physicians should be considered and further evaluated.

PMID- 29174833 TI - Does Prescription Opioid Shopping Increase Overdose Rates in Medicaid Beneficiaries? AB - STUDY OBJECTIVE: The link between prescription opioid shopping and overdose events is poorly understood. We test the hypothesis that a history of prescription opioid shopping is associated with increased risk of overdose events. METHODS: This is a secondary analysis of a linked claims and controlled substance dispense database. We studied adult Medicaid beneficiaries in 2014 with prescription opioid use in the 6 months before an ambulatory care or emergency department visit with a pain-related diagnosis. The primary outcome was a nonfatal overdose event within 6 months of the cohort entry date. The exposure of interest (opioid shopping) was defined as having opioid prescriptions by different prescribers with greater than or equal to 1-day overlap and filled at 3 or more pharmacies in the 6 months before cohort entry. We used a propensity score to match shoppers with nonshoppers in a 1:1 ratio. We calculated the absolute difference in outcome rates between shoppers and nonshoppers. RESULTS: We studied 66,328 patients, including 2,571 opioid shoppers (3.9%). There were 290 patients (0.4%) in the overall cohort who experienced a nonfatal overdose. In unadjusted analyses, shoppers had higher event rates than nonshoppers (rate difference of 4.4 events per 1,000; 95% confidence interval 0.8 to 7.9). After propensity score matching, there were no outcome differences between shoppers and nonshoppers (rate difference of 0.4 events per 1,000; 95% confidence interval 4.7 to 5.5). These findings were robust to various definitions of opioid shoppers and look-back periods. CONCLUSION: Prescription opioid shopping is not independently associated with increased risk of overdose events. PMID- 29174834 TI - A Systematic Review and Meta-Analysis of the Management and Outcomes of Isolated Skull Fractures in Children. AB - STUDY OBJECTIVE: Most studies of children with isolated skull fractures have been relatively small, and rare adverse outcomes may have been missed. Our aim is to quantify the frequency of short-term adverse outcomes of children with isolated skull fractures. METHODS: PubMed, EMBASE, the Cochrane Library, Scopus, Web of Science, and gray literature were systematically searched to identify studies reporting on short-term adverse outcomes of children aged 18 years or younger with linear, nondisplaced, isolated skull fractures (ie, without traumatic intracranial injury on neuroimaging). Two investigators independently reviewed identified articles for inclusion, assessed quality, and extracted relevant data. Our primary outcome was emergency neurosurgery or death. Secondary outcomes were hospitalization and new intracranial hemorrhage on repeated neuroimaging. Meta analyses of pooled estimate of each outcome were conducted with random-effects models, and heterogeneity across studies was assessed. RESULTS: Of the 587 studies screened, the 21 that met our inclusion criteria included 6,646 children with isolated skull fractures. One child needed emergency neurosurgery and no children died (pooled estimate 0.0%; 95% confidence interval [CI] 0.0% to 0.0%; I2=0%). Of the 6,280 children with known emergency department disposition, 4,914 (83%; 95% CI 71% to 92%; I2=99%) were hospitalized. Of the 569 children who underwent repeated neuroimaging, 6 had new evidence of intracranial hemorrhage (0.0%; 95% CI 0.0% to 9.0%; I2=77%); none required operative intervention. CONCLUSION: Children with isolated skull fractures were at extremely low risk for emergency neurosurgery or death, but were frequently hospitalized. Clinically stable children with an isolated skull fracture may be considered for outpatient management in the absence of other clinical concerns.

PMID- 29174836 TI - Accuracy and Reliability of Emergency Department Triage Using the Emergency Severity Index: An International Multicenter Assessment. AB - STUDY OBJECTIVE: We assess accuracy and variability of triage score assignment by emergency department (ED) nurses using the Emergency Severity Index (ESI) in 3 countries. In accordance with previous reports and clinical observation, we hypothesize low accuracy and high variability across all sites. METHODS: This cross-sectional multicenter study enrolled 87 ESI-trained nurses from EDs in Brazil, the United Arab Emirates, and the United States. Standardized triage scenarios published by the Agency for Healthcare Research and Quality (AHRQ) were used. Accuracy was defined by concordance with the AHRQ key and calculated as percentages. Accuracy comparisons were made with one-way ANOVA and paired t test. Interrater reliability was measured with Krippendorff's alpha. Subanalyses based on nursing experience and triage scenario type were also performed. RESULTS: Mean accuracy pooled across all sites and scenarios was 59.2% (95% confidence interval [CI] 56.4% to 62.0%) and interrater reliability was modest (alpha=.730; 95% CI .692 to .767). There was no difference in overall accuracy between sites or according to nurse experience. Medium-acuity scenarios were scored with greater accuracy (76.4%; 95% CI 72.6% to 80.3%) than high- or low-acuity cases (44.1%, 95% CI 39.3% to 49.0% and 54%, 95% CI 49.9% to 58.2%), and adult scenarios were scored with greater accuracy than pediatric ones (66.2%, 95% CI 62.9% to 69.7% versus 46.9%, 95% CI 43.4% to 50.3%). CONCLUSION: In this multinational study, concordance of nurse-assigned ESI score with reference standard was universally poor and variability was high. Although the ESI is the most popular ED triage tool in the United States and is increasingly used worldwide, our findings point to a need for more reliable ED triage tools.

PMID- 29174837 TI - Accuracy and Discomfort of Different Types of Intranasal Specimen Collection Methods for Molecular Influenza Testing in Emergency Department Patients. AB - STUDY OBJECTIVE: While development is under way of accurate, point-of-care molecular tests for influenza infection, the optimal specimen type for molecular tests remains unclear. Compared with standard nasopharyngeal swab specimens, less invasive nasal swab and midturbinate swab specimens may cause less patient discomfort and be more suitable for routine emergency department (ED) testing, although possibly at the expense of diagnostic accuracy. We compare both the accuracy of a polymerase chain reaction molecular influenza test and discomfort between these 3 intranasal specimen types. METHODS: A convenience sample of adult and pediatric patients with influenza-like illness and presenting to 2 Northern California EDs and 2 EDs in Santiago, Chile, was prospectively enrolled during the 2015 to 2016 influenza season. Research nurses collected nasopharyngeal swab, midturbinate swab, and nasal swab specimens from each subject and assessed discomfort on a validated 6-point scale. Specimens were tested for influenza A and B by real-time polymerase chain reaction at reference laboratories. Outcome measures were comparison of test performance between nasal swab and midturbinate swab, when compared with a reference standard nasopharyngeal swab; and comparison of discomfort between all 3 specimen types. RESULTS: Four hundred eighty-four subjects were enrolled, and all 3 swabs were obtained for each subject; 14% were children. The prevalence of influenza (A or B) was 30.0% (95% confidence interval [CI] 26.0% to 34.8%). The sensitivity for detecting influenza was 98% (95% CI 94.25% to 99.65%) with the midturbinate swab versus 84.4% (95% CI 77.5% to 89.8%) with the nasal swab, difference 13.6% (95% CI 8.2% to 19.3%). Specificity was 98.5% (95% CI 96.6% to 99.5%) with the midturbinate swab versus 99.1% (95% CI 97.4% to 99.8%) with the nasal swab, difference -0.6% (95% CI -1.8% to 0.6%). Swab discomfort levels correlated with the depth of the swab type. Median discomfort scores for the nasal swab, midturbinate swab, and nasopharyngeal swab were 0, 1, and 3, respectively; the median differences were nasopharyngeal swab midturbinate swab 2 (95% CI 1 to 2), nasopharyngeal swab-nasal swab 3 (95% CI 2 to 3), and midturbinate swab-nasal swab 1 (95% CI 1 to 2). CONCLUSION: Compared with the reference standard nasopharyngeal swab specimen, midturbinate swab specimens provided a significantly more comfortable sampling experience, with only a small sacrifice in sensitivity for influenza detection. Nasal swab specimens were significantly less sensitive than midturbinate swab. Our results suggest the midturbinate swab is the sampling method of choice for molecular influenza testing in ED patients. PMID- 29174839 TI - A National Study of Outpatient Health Care Providers' Effect on Emergency Department Visit Acuity and Likelihood of Hospitalization. AB - STUDY OBJECTIVE: Many policymakers believe that expanding access to outpatient care will reduce emergency department (ED) use. However, outpatient health care providers often refer their patients to EDs for evaluation and management. We examine the factors underlying outpatient provider referral, its effect on ED visit volume, and whether referred ED visits are more likely to result in hospitalization than self-referred visits. METHODS: We conducted a cross sectional study of 19,342 adult (>18 years) respondents to the 2012 to 2014 National Health Interview Survey who reported they had visited an ED at least once in the past 12 months, representing an estimated 44,152,870 US adults. We categorized individuals as having been referred to the ED by an outside health care provider if they responded affirmatively to "your health care provider advised you to go" as a reason for their most recent ED visit. We performed descriptive analyses and logistic regressions to examine factors associated with outpatient health care provider referral to the ED. Respondents could choose multiple other reasons for their most recent ED visit, and we used existing Centers for Disease Control and Prevention guidelines to group these reasons into 2 categories: seriousness of the medical condition and lack of access to other providers. Our 2 main outcomes were whether an outpatient health care provider referred an individual to the ED and whether that ED visit resulted in hospitalization. RESULTS: Of the 44,152,870 US adults (18.58%; 95% confidence interval [CI] 18.21% to 18.95%) with one or more ED visits in the previous 12 months, 10,913,271 (24.72%; 95% CI 23.80% to 25.64%) were referred to the ED by an outpatient provider. Respondents who reported their ED visit was due to the seriousness of their medical condition were more likely to be referred to the ED (odds ratio [OR] 2.18; 95% CI 1.91 to 2.49), whereas those reporting a lack of access to other providers were less likely to be referred (OR 0.58; 95% CI 0.52 to 0.64). Visits referred to the ED were more likely to result in hospitalization than self-referrals (OR 2.07; 95% CI 1.87 to 2.31). CONCLUSION: Almost one quarter of individuals' most recent ED visits were driven by referrals from outpatient health care providers. Being referred to the ED by an outpatient provider is strongly associated with the seriousness of one's medical condition, which also increases the odds of hospitalization compared with ED discharge. After controlling for seriousness of medical condition, ED referral by an outpatient provider continues to have an independent association with hospitalization.

AB - Recent tuberculosis (TB) drug discovery programme involve continuous pursuit for new chemical entity (NCE) which can be not only effective against both susceptible and resistant strains of Mycobacterium tuberculosis (Mtb) but also safe and faster acting with the target, thereby shortening the prolonged TB treatments. We have identified a potential nitrofuranyl methyl piperazine derivative, IIIM-MCD-211 as new antitubercular agent with minimum inhibitory concentration (MIC) value of 0.0072 MUM against H37Rv strain. Objective of the present study is to investigate physicochemical, pharmacokinetic, efficacy and toxicity profile using in-silico, in-vitro and in-vivo model in comprehensive manner to assess the likelihood of developing IIIM-MCD-211 as a clinical candidate. Results of computational prediction reveal that compound does not violate Lipinski's, Veber's and Jorgensen's rule linked with drug like properties and oral bioavailability. Experimentally, IIIM-MCD-211 exhibits excellent lipophilicity that is optimal for oral administration. IIIM-MCD-211 displays evidence of P-glycoprotein (P-gp) induction but no inhibition ability in rhodamine cell exclusion assay. IIIM-MCD-211 shows high permeability and plasma protein binding based on parallel artificial membrane permeability assay (PAMPA) and rapid equilibrium dialysis (RED) assay model, respectively. IIIM-MCD-211 has adequate metabolic stability in rat liver microsomes (RLM) and favourable pharmacokinetics with admirable correlation during dose escalation study in Swiss mice. IIIM-MCD-211 has capability to appear into highly perfusable tissues. IIIM MCD-211 is able to actively prevent progression of TB infection in chronic infection mice model. IIIM-MCD-211 shows no substantial cytotoxicity in HepG2 cell line. In acute toxicity study, significant increase of total white blood cell (WBC) count in treatment group as compared to control group is observed. Overall, amenable preclinical data make IIIM-MCD-211 ideal candidate for further development of oral anti-TB agent. PMID- 29174841 TI - New hope for hyperlipidemia management: Inclisiran.

PMID- 29174843 TI - An Efficient Single-Cell RNA-Seq Approach to Identify Neoantigen-Specific T Cell Receptors. AB - The adoptive transfer of neoantigen-reactive tumor-infiltrating lymphocytes (TILs) can result in tumor regression in patients with metastatic cancer. To improve the efficacy of adoptive T cell therapy targeting these tumor-specific mutations, we have proposed a new therapeutic strategy, which involves the genetic modification of autologous T cells with neoantigen-specific T cell receptors (TCRs) and the transfer of these modified T cells back to cancer patients. However, the current techniques to isolate neoantigen-specific TCRs are labor intensive, time consuming, and technically challenging, not suitable for clinical applications. To facilitate this process, a new approach was developed, which included the co-culture of TILs with tandem minigene (TMG)-transfected or peptide-pulsed autologous antigen-presenting cells (APCs) and the single-cell RNA sequencing (RNA-seq) analysis of T cells to identify paired TCR sequences associated with cells expressing high levels of interferon-gamma (IFN-gamma) and interleukin-2 (IL-2). Following this new approach, multiple TCRs were identified, synthesized, cloned into a retroviral vector, and then transduced into donor T cells. These transduced T cells were shown to specifically recognize the neoantigens presented by autologous APCs. In conclusion, this approach provides an efficient procedure to isolate neoantigen-specific TCRs for clinical applications, as well as for basic and translational research. PMID- 29174844 TI - Neuromuscular adaptations in older males and females with knee osteoarthritis during weight-bearing force control. AB - BACKGROUND: Females exhibit significantly greater incidence, prevalence, and severity of osteoarthritis (OA) compared to males. Despite known biological, morphological, and functional differences between males and females, there has been little sex-related investigation into sex-specific biomechanical and neuromuscular responses to OA. OBJECTIVE: To identify sex-related differences in OA-affected adults and within-sex differences between healthy and OA-affected adults' muscular activation patterns during lower limb loading. METHODS: Thirty adults with OA and 36 controls completed a standing ground reaction force (GRF) matching protocol requiring participants to expose equal body weight to each leg and modulate horizontal GRFs while maintaining constant joint positions. Electromyography was plotted as a function of GRF direction to depict muscle activation patterns. Muscles were classified as a general joint stabilizer, specific joint stabilizer or moment actuator by quantifying activation patterns with a test of asymmetry, specificity index and mean direction of activity. Lower limb kinematics and kinetics were also recorded. RESULTS: In general, muscle roles as it relates to joint stability did not differ between groups. Compared to controls, both males and females with OA demonstrated greater rectus femoris activity and reduced knee rotation moments. Females with OA had significantly greater biceps femoris and gastrocnemius activity during respective lateral, and anterior-medial loading directions compared to males with OA. CONCLUSIONS: We identified fundamental differences in muscular stabilization strategies in older adults with OA as well as sex-related changes in neuromuscular function that may influence joint loading conditions and provide insight into the greater incidence of knee OA in females. PMID- 29174845 TI - Impact of ventilation systems and energy savings in a building on the mechanisms governing the indoor radon activity concentration. AB - For a given radon potential in the ground and a given building, the parameters affecting the indoor radon activity concentration (IRnAC) are indoor depressurization of a building and its air change rate. These parameters depend mainly on the building characteristics, such as airtightness, and on the nature and performances of the ventilation system. This study involves a numerical sensitivity assessment of the indoor environmental conditions on the IRnAC in buildings. A numerical ventilation model has been adapted to take into account the effects of variations in the indoor environmental conditions (depressurization and air change rate) on the radon entry rate and on the IRnAC. In the context of the development of a policy to reduce energy consumption in a building, the results obtained showed that IRnAC could be strongly affected by variations in the air permeability of the building associated with the ventilation regime. PMID- 29174846 TI - Quantitative proteomics study of host response to virulent and attenuated pseudorabies virus infection in mouse brain. AB - Bartha, the pseudorabies virus (PRV) vaccine strain, is widely used in studies of neuronal circuit-tracing, due to its attenuated virulence and retrograde spreading. However, we know little regarding the molecular mechanisms of PRV infection and spreading between structurally connected neurons. In this study, we systematically analyzed the host brain proteomes after acute infection with PRV, attempting to identified the proteins involved in the processes. Mice were injected with PRV-Bartha and PRV-Becker (PRV-Bartha's wild-type parent strain) in the olfactory system, the proteomes of the brain and synaptosome were analyzed and compared at various infection intervals using mass spectrometry-based proteomics techniques. In all, we identified >100 PRV-infection regulated proteins at the whole-tissue level and the synaptosome level. While at whole tissue level, bioinformatics analyses mapped most of the regulations to the inflammation pathways, at the synaptosome level, most of those to synaptic transmission, cargo transport and cytoskeleton organization. We established regulated protein networks demonstrating distinct cellular regulation pattern between the global and the synaptosome levels. Moreover, we identified a series of potentially PRV-strain-specific regulated proteins with diverse biological functions. This study may provide new clues for molecular mechanisms for PRV infection and spread. PMID- 29174848 TI - [Back loss cover in orthopedic surgery by helical lumbar perforator flaps: About 6 cases]. AB - INTRODUCTION: The existence of voluminous paralumbar perforators allows a simplification of the coverage of the lumbar region. MATERIALS AND METHODS: The authors present a series about lumbar loss substance following orthopedic surgery, from 2012 to 2017. Coverage was provided by a fascio-cutaneous lumbar perforator flap. RESULTS: Six patients were operated with mean age of 62.3 years, with an average follow-up of 16 months (up 6 to 41 months). Substance losses were secondary to a carcinologic excision, to a radiodermitis excision and to four debridements after infection of the operative site. In five cases, the reconstruction was performed by one lumbar perforator flap, and in one case by two lumbar perforator flaps. The average size of the substance losses was 171.91 cm2 (up 78 to 250 cm2). The average size of the flaps taken was 161 cm2 (up 50 to 250 cm2). The donor site was self-closing without sequelae. The postoperative sequences were simple and marked by a single partial necrosis of a flap, with a favorable evolution after directed healing. The quality of the cover was good with excellent trophicity. CONCLUSION: Lumbar perforator helical fascio-cutaneous flaps are a reliable means of covering the loss of substances in the lumbar region. The use of these flaps makes it possible to avoid the taking of complex myo-cutaneous flaps, causing sequelae of the donor site in a location difficult to cover. PMID- 29174847 TI - Molecular pathology of total knee arthroplasty instability defined by RNA-seq. AB - Total knee arthroplasty (TKA) is a durable and reliable procedure to alleviate pain and improve joint function. However, failures related to flexion instability sometimes occur. The goal of this study was to define biological differences between tissues from patients with and without flexion instability of the knee after TKA. Human knee joint capsule tissues were collected at the time of primary or revision TKAs and analyzed by RT-qPCR and RNA-seq, revealing novel patterns of differential gene expression between the two groups. Interestingly, genes related to collagen production and extracellular matrix (ECM) degradation were higher in samples from patients with flexion instability. Partitioned clustering analyses further emphasized differential gene expression patterns between sample types that may help guide clinical interpretations of this complication. Future efforts to disentangle the effects of physical and biological (e.g., transcriptomic modifications) risk factors will aid in further characterizing and avoiding flexion instability after TKA. PMID- 29174849 TI - [The advantages in using cyanoacrylate glue over skin staples as a method of skin graft fixation in the pediatric burns population]. AB - INTRODUCTION: Local postoperative care and burn wound management can present with a certain degree of difficulty in the pediatric population. While the use of skin staples as a method of skin graft fixation is a well-known, rapid and simple method, their removal can be painful and may necessitate some sedation or even general anesthesia. We studied in this article the advantages and economic value of using the cyanoacrylate glue as a fixation method for skin grafts. MATERIALS AND METHODS: A comparative study was carried out from 2012 to 2016. Hundred and eighteen infants with burns up to 5% of total body surface area were included in the study. Seventy-two infants had split thickness skin grafts fixed with skin staples. Forty-six infants had split thickness skin grafts fixed with cyanoacrylate glue. We compared the quality of graft, the sedation used during the first postoperative dressing, the length of hospital stay, the amount of glue used and the presence of complications. RESULTS: There is a difference between the two groups studied in terms of age and total burn surface area. The rate of graft take was 100% in both groups. The first postoperative dressing was carried out without the use of powerful analgesia in the cyanoacrylate group, while it was necessary to use general anesthesia in 64% of the skin staples group. The average length of stay in hospital after skin grafting was 4.9 days for the cyanoacrylate glue versus 6.5 days in the skin staples group. No complications were noted in the 2 groups. CONCLUSION: The use of cyanoacrylate glue allows rapid fixation of skin grafts and avoid general anesthesia for postoperative cares. Subsequently the length of hospital stay is reduced within 25%. The medico economic value of glue protocol is highly significant compared to skin staples, while having similar good results and without significant problems. PMID- 29174850 TI - Association Between Pepsin in the Saliva and the Subjective Symptoms in Patients With Laryngopharyngeal Reflux. AB - OBJECTIVES: Our study was designed to further evaluate the relationships between the saliva pepsin level and the symptoms and quality of life of patients with laryngopharyngeal reflux (LPR). STUDY DESIGN: A prospective cohort study without controls. SETTING: Tertiary teaching hospital. SUBJECTS AND METHODS: We analyzed 50 patients diagnosed with LPR by 24-hour multichannel intraluminal impedance pH monitoring. All subjects were instructed to collect saliva samples upon waking in the morning. The saliva pepsin levels were analyzed using enzyme-linked immunosorbent assay. The Reflux Symptom Index, Reflux Finding Score, Laryngopharyngeal Reflux-Health-Related Quality of Life, and Short Form 36 survey were administered. RESULTS: The pepsin was detected in the saliva of 41 patients with LPR (17.15 +/- 20.42 ng/mL). Nine patients did not have pepsin in the saliva. There were no significant associations between the pepsin level in the saliva and Reflux Symptom Index, Laryngopharyngeal Reflux-Health-Related Quality of Life, or Short Form 36 of patients with LPR. CONCLUSION: The saliva pepsin level is not significantly correlated with LPR symptoms or quality of life in LPR patients. It may be true that there is no association between pepsin levels and LPR symptoms, but this lack of association does not prove the lack of pathophysiological effect. PMID- 29174851 TI - Hepatoprotective effect of quercetin via TRAF6/JNK pathway in acute hepatitis. AB - Quercetin, as a member of the flavonoids family, has many beneficial properties. The aim of our study was to evaluate the protective effect of quercetin in ConA induced hepatitis in mice, and to clarify its mechanism of action. Hepatitis was induced by using ConA (25 mg/kg), and quercetin was administered intragastrically at the dose of 100 mg/kg or 200 mg/kg for 5 days before ConA injection. The serum levels of liver enzymes, inflammatory cytokines and other marker proteins were determined at 2 h, 8 h and 24 h after ConA injection. Following ConA injection, serum levels of liver enzymes and inflammatory cytokines were significantly increased. Quercetin ameliorated liver damage and histopathological changes, and suppressed the release of inflammatory cytokines. The expression of Bax, Bcl-2, Beclin-1, LC3, P62 and caspase 9 were markedly affected by quercetin pretreatment. The expression of TRAF6 and p-JNK were decreased in the quercetin groups. Quercetin attenuated apoptosis and autophagy in ConA-induced autoimmune hepatitis by inhibiting TRAF6/JNK pathway. PMID- 29174853 TI - Inonotus obliquus extract induces apoptosis in the human colorectal carcinoma's HCT-116 cell line. AB - Because of irregular dietary habits and lifestyle in Taiwan, the incidence and mortality rate of colorectal cancer have been increasing rapidly these years. This study investigated the inhibitory activity against the proliferation of human colorectal cancer HCT-116 cells by Inonotus obliquus extracts obtained from submerged fermentation. Cell viability was measured by the reduction of MTT and cell membrane integrity was determined by lactic dehydrogenase (LDH) release. The mRNA expression of proapoptosis and antiapoptosis mediators was assayed by real time PCR, and the levels of p53 and NF-kappaB p65 were assessed using Western blot analysis. Furthermore, the influences of I. obliquus extracts to HCT-116 cells were evaluated by caspase-3 activity. The results can be summarized as, for the mitochondrial apoptotic pathway, quantitative RT-PCR data showed up regulation of proapoptotic genes (Bax, bad, and caspase-3) and increased Bax/bcl 2 ratio by I. obliquus extracts. Moreover, treating with 20 mg/mL I. obliquus extracts augmented caspase-3 activity in HCT-116 cells. Induction of cell cycle G0/G1 phase arrest: I. obliquus extracts up-regulated the mRNA expression of proapoptotic genes (p53, p21WAF1/CIP1) and down-regulated antiapoptotic gene (CyclinD1), while extracts of I. obliquus mycelia increased the expressions of p53 protein in HCT-116 cells. I. obliquus extracts decreased the expression of NF kappaB p65 protein and COX-2 gene in HCT-116 cells. Taking together, I. obliquus extracts may be used as a potentially novel food material for health care to improve the treatment of colorectal cancer. PMID- 29174852 TI - Activation of Epac alleviates inflammation and vascular leakage in LPS-induced acute murine lung injury. AB - Exchange protein directly activated by cAMP (Epac) is an important molecule in cAMP signal transduction, but the effect of Epac on lipopolysaccharide (LPS) induced acute lung injury (ALI) is unclear. In this study, we treated in vitro and in vivo models with the Epac activator 8CPT to determine the effect and related mechanisms of Epac. The in vitro results indicate that 8CPT inhibits lipopolysaccharide (LPS)-induced tumor necrosis factor-alpha (TNF-alpha) release from mouse macrophages (MH-S), whereas the protein kinase A (PKA) activator 6BnZ has no effect. Furthermore, Epac over-expression can significantly suppress TNF alpha release from LPS induced MH-S cell, while Epac siRNA can slightly increase TNF-alpha release. Moreover, 8CPT reduces LPS-induced microvascular permeability in human pulmonary microvascular endothelial cells (HPMVECs), whereas the PKA activator 6BnZ has no effect. In mice with LPS-induced ALI, 8CPT significantly reduces LPS-induced inflammatory cytokine release, neutrophil recruitment, and albumin leakage. LPS simultaneously decreases the Epac but not the PKA levels. However, 8CPT reverses the decreased Epac levels. Furthermore, the mechanism involves the small GTPase Rac1/2 but not the mitogen-activated protein kinase (MAPK) pathway. Thus, Epac activation reduces inflammation and microvascular permeability in LPS-induced lung injury and an Epac activator represents a novel choice for the early therapy of ALI. PMID- 29174854 TI - DUSP19 regulates IL-1beta-induced apoptosis and MMPs expression in rat chondrocytes through JAK2/STAT3 signaling pathway. AB - Osteoarthritis (OA) is a disease with degeneration of articular cartilage and its development and progression is characterized by chondrocyte apoptosis. To examine whether DUSP19 and inhibitor of the JAK2/STAT3 will influence the response of rat chondrocytes cultured with IL-1beta. Dose-response studies were conducted under IL-1beta conditions. In separate experiments, chondrocytes were treated with an appropriate concentration of IL-1beta with either DUSP19-expressing constructs or AG490, whereas chondrocytes were also treated with DUSP19-RNA interference constructs with or without AG490. The expression of DUSP19, apoptosis markers, JAK2/STAT3 and phosphorylation of JAK2/STAT3 was measured by Real-time PCR and/or western blot assay. CCK-8 assay and Annexin V/propidium iodide staining was used to detect chondrocyte viability and apoptosis, respectively. IL-1beta dose dependently decreased the expression of DUSP19 and the viability of chondrocytes. Chondrocytes with DUSP19 up-regulation inhibited IL-1beta-induced increases in the ratio of p-JAK2/JAK2 and p-STAT3/STAT3 expression as well as cell apoptosis. However, DUSP19 down-regulation mimicked the effect of IL-1beta on JAK2/STAT3 activity and chondrocyte apoptosis. AG490 inhibited JAK2/STAT3 activation as well as apoptosis in chondrocytes induced by IL-1beta or DUSP19 down-regulation, evidenced by decreased expression of Bax, Caspase-3 and increased Bcl-2 expression as well as MMP-3, -9 and -13 expressions. Taken together, our results demonstrate that DUSP19 up-regulation inhibited IL-1beta-induced chondrocytes apoptosis and MMPs expression through inactivating JAK2/STAT3 pathway. PMID- 29174855 TI - Simulating uni- and bi-directional pedestrian movement on stairs by considering specifications of personal space. AB - This paper presents an enhanced model that considers the specifications of personal space to describe uni- and bi-directional pedestrian movement on stairs. The shape of the personal space of each pedestrian is regarded as an oval shape, which is composed of four arcs, to precisely quantify movements. Specific models that facilitate the simulation of movement include adjustments to individual speeds based on the proximity of other members, conflict avoidance, overtaking, and direction finding. By implementing these parameters in the simulation, basic data concerning these movement behaviours were collected from the experiment, which was carried out at one a Shanghai subway station. Twenty-four young college students participated in this experiment. Numerical simulation results for a stochastic case under those parameters were obtained. The fundamental diagrams and moving behaviours according to different proportions of ascending and descending pedestrians are analysed and discussed. The results indicate that the simulation platform for personal space can serve as a useful tool to evaluate pedestrian movement on stairs. PMID- 29174856 TI - The Child Neurology Trainee-as-Teacher: A Clinical Teaching Curriculum Tailored to Learners' Needs and Developmental Roles. AB - BACKGROUND: Clinical teaching skills programs for resident physicians are increasingly offered. Less attention has been devoted to the unique educational roles of specialty residents and subspecialty fellows, many of whom will become academic faculty physicians. These teaching roles, and therefore a trainee's learning needs and motivation, also change over the course of training. METHODS: We designed and implemented a two-year longitudinal teaching curriculum for child neurology and neurodevelopmental disabilities residents using adult learning theory principles: experiential learning and immediate applicability to specific roles. Core modules included teaching in clinical settings, adult learning, and giving feedback. Training-year-specific modules for second-year residents (n = 11) and final-year residents (n = 10) included teaching through consultation and promoting clinical reasoning in supervisory roles. Learners completed an 11-item self-assessment before and after intervention. RESULTS: The overall program significantly increased residents' self-assessed knowledge of how to assess the level of a learner (P = 0.02, Cohen d = 0.84) and comfort and skill in giving feedback (P = 0.04, d = 0.64; P = 0.04, d = 0.71). The final-year-specific curriculum additionally increased self-assessed skill in teaching same-specialty residents (P = 0.05, d = 1.07) and in promoting clinical reasoning (P = 0.03, d = 1.14). The program was rated highly by trainees and faculty, and has been adopted as an ongoing part of our training program. CONCLUSIONS: Our experience offers a reproducible model and theoretical framework for child neurology, neurodevelopmental disabilities, and other specialty programs to develop customized trainee-as-teacher curricula with specialty- and training-year specific content. PMID- 29174857 TI - The Utility of Collaterals as a Biomarker in Pediatric Unilateral Intracranial Arteriopathy. AB - BACKGROUND: Intracranial arteriopathies are frequent causes of pediatric stroke and important risk factors for stroke recurrence. Without tissue diagnosis, vascular imaging is relied upon to identify the underlying etiology and prognosis. We hypothesized that children with unilateral intracranial arteriopathy with lenticulostriate collaterals would demonstrate distinct vascular outcomes compared with children without collaterals. METHODS: We retrospectively identified children with unilateral intracranial arteriopathy from two institutions. Two blinded raters from each institution reviewed magnetic resonance or digital subtraction angiography at baseline and >=12 months. Patients were grouped according to presence or absence of lenticulostriate collaterals. Clinical features and vascular imaging outcomes were compared using univariate analysis and multivariate logistic regression. RESULTS: Forty-four children were included: 22 males, median age 8.2 years (range two to 16.9 years), and further stratified into the collateral group (n = 20) and non-collateral group (n = 24), with median follow-up of 25.5 months and 23 months, respectively. Both groups demonstrated similar rates of progression on vascular imaging at >=12 months, 50% in the collateral group versus 37.5% in the non-collateral group (P > 0.05). The collateral group was associated with asymptomatic clinical presentation, normal brain MRI, border zone infarcts, and either vascular stabilization or new contralateral disease. The non-collateral group demonstrated either vascular improvement or discordant progression (combination of improved and progressive lesions). Using a multivariate model, collaterals continued to be an independent predictor of vascular outcome. CONCLUSIONS: This study suggests that lenticulostriate collaterals in children with unilateral intracranial arteriopathy may serve as a useful neuroimaging biomarker that helps to stratify patients with distinct clinical features and patterns of vascular evolution. PMID- 29174858 TI - Visualized Evaluation of Blood Flow to the Gastric Conduit and Complications in Esophageal Reconstruction. AB - BACKGROUND: Evaluation of the blood supply to gastric conduits is critically important to avoid complications after esophagectomy. We began visual evaluation of blood flow using indocyanine green (ICG) fluorescent imaging in July 2015, to reduce reconstructive complications. In this study, we aimed to statistically verify the efficacy of blood flow evaluation using our simplified ICG method. STUDY DESIGN: A total of 285 consecutive patients who underwent esophagectomy and gastric conduit reconstruction were reviewed and divided into 2 groups: before and after introduction of ICG evaluation. The entire cohort and 68 patient pairs after propensity score matching (PS-M) were evaluated for clinical outcomes and the effect of visualized evaluation on reducing the risk of complication. RESULTS: The leakage rate in the ICG group was significantly lower than in the non-ICG group for each severity grade, both in the entire cohort (285 subjects) and after PS-M; the rates of other major complications, including recurrent laryngeal nerve palsy and pneumonia, were not different. The duration of postoperative ICU stay was approximately 1 day shorter in the ICG group than in the non-ICG group in the entire cohort, and approximately 2 days shorter after PS M. Visualized evaluation of blood flow with ICG methods significantly reduced the rate of anastomotic complications of all Clavien-Dindo (CD) grades. Odds ratios for ICG evaluation decreased with CD grade (0.3419 for CD >= 1; 0.241 for CD >= 2; and 0.2153 for CD >= 3). CONCLUSIONS: Objective evaluation of blood supply to the reconstructed conduit using ICG fluorescent imaging reduces the risk and degree of anastomotic complication.

PMID- 29174861 TI - Evaluation of saliva and plasma cytokine biomarkers in patients with oral squamous cell carcinoma. AB - The aim of this study was to investigate potential biomarkers in human saliva and plasma to aid in the early diagnosis of oral squamous cell carcinoma (OSCC). Saliva and plasma samples obtained from OSCC patients (n=41) and non-oral cancer patients (n=24) were analyzed by Luminex Bead-based Multiplex Assay. Data were analyzed using the non-parametric Mann-Whitney U-test, Kruskal-Wallis test, and receiver operating characteristics curve (ROC) to evaluate the predictive power of 14 biomarkers individually for OSCC diagnosis. The plasma level of IP-10 in early OSCC differed significantly from that in controls. Among the salivary biomarkers, IL-1beta, IL-6, IL-8, MIP-1beta, eotaxin and IFN-gamma and TNF-alpha showed significant differences between OSCC patients and controls. With respect to carcinogenesis, significant differences in plasma levels of eotaxin, G-CSF, and IL-6 were found between OSCC stages III/IV and OSCC stages I/II. The area under the curve (AUC) for OSCC vs. control was greater than 0.7 for plasma IP-10 and saliva IL-1beta, IL-6, IL-8, and TNF-alpha. The study findings indicate that salivary biomarkers may serve a useful role as a complementary adjunct for the early detection of oral OSCC. With regard to the evaluation of tumour progression, plasma eotaxin, G-CSF, and IL-6 may help in the detection of advanced OSCC. However, the correlation between saliva and plasma biomarkers in OSCC was weak. PMID- 29174862 TI - Clinical implications of taste thresholds in patients with odontogenic maxillary sinusitis. AB - Patients with odontogenic maxillary sinusitis (OMS) often complain of reduced taste sensitivity as well as nasal obstruction. The filter paper disc method (the conventional gustatory test) was applied to nine patients who underwent sinus surgery to open the inferior nasal meatus and sinus drainage, on three different days: 1day prior to surgery, 7days postoperative, and 28days postoperative. The same test was applied to nine non-clinical participants with or without clipping the nose to interfere with smooth nasal airflow on two different days. Acquired recognition thresholds for the four basic tastes of sweet, salty, sour, and bitter were assessed. In OMS patients, the recognition thresholds for all four tastes were markedly decreased at 7 and 28days postoperative, and subjective taste sensitivity and the elimination of nasal obstruction was improved. The mean recognition threshold for the four tastes correlated negatively with taste satisfaction scores. Clipping the nose in non-clinical participants induced increases in gustatory detection and recognition thresholds. Despite the small sample size and different ages and sexes of the study subjects, it was demonstrated that nasal obstruction in OMS patients and nose clipping in non clinical subjects reduce taste reactivity, and surgical intervention to promote nasal airflow recovers impaired taste reactivity. PMID- 29174863 TI - Adolescent environmental enrichment prevents the emergence of schizophrenia-like abnormalities in a neurodevelopmental model of schizophrenia. AB - In the present study, we investigated whether exposure to an enriched environment (EE) during adolescence might affect the behavioural dysfunction (sensorimotor gating deficit, memory and social interaction impairments) and neurochemical changes (GAD67 expression, histone methylation) induced by methylazoxymethanol (MAM) in the MAM-E17 rat model of schizophrenia. EE was introduced for 7 days in early adolescence (days 23-29), and behavioural and biochemical studies were performed on adult rats at postnatal day 70. The results showed that exposure to EE prevented the development of adult behavioural deficits induced by prenatal MAM administration. EE also prevented the decrease in GAD67 mRNA and protein levels induced by MAM in the medial prefrontal cortex (mPFC). Moreover, EE inhibited the reductions in the amount of Gad1 bound to H3K4me3 and in the total H3K4me3 protein level induced by prenatal MAM administration in the adult mPFC. However, there was no effect of EE on behaviour or levels of the various neurochemical markers in adult rats prenatally treated with vehicle. Thus, these results indicate that EE exposure during early adolescence may inhibit the development of schizophrenia related symptoms through epigenetic mechanisms that regulate the expression of genes (e.g., Gad1) that are impaired in schizophrenia. PMID- 29174864 TI - A multi-centre, randomised, double-blind, placebo-controlled clinical trial of methylphenidate in the initial treatment of acute mania (MEMAP study). AB - : Based on many clinical and preclinical findings the 'vigilance regulation model of mania' postulates that an unstable regulation of wakefulness is a pathogenetic factor in both mania and Attention Deficit Hyperactivity Disorder (ADHD) and induces hyperactivity and sensation seeking as an autoregulatory attempt to stabilize wakefulness. Accordingly, stimulant medications with their vigilance stabilizing properties could have rapid antimanic effects similar to their beneficial effects in ADHD. The MEMAP study - a multi-center, double-blind, placebo-controlled and randomized clinical trial (RCT) - assessed the antimanic efficacy and safety of a 2.5-day treatment with methylphenidate (20-40mg/day). Of 157 screened patients with acute mania, 42 were randomly assigned to receive 20 40mg per day of methylphenidate in one or two applications, or placebo. The primary outcome was the change in Young Mania Rating Scale (YMRS) sum scores from baseline to day 2.5 in the methylphenidate group compared to the placebo group. A group sequential design was chosen to justify early RCT termination based on efficacy or futility at an interim analysis after inclusion of 40 patients. In the interim analysis, the change from baseline in the YMRS total score at day 2.5 was not significantly different between both groups (F(1,37)=0.23; p=0.64). Thus, futility was declared for methylphenidate and the RCT was stopped. In summary, although methylphenidate was well tolerated and safe in the full analysis set, it failed to show efficacy in the treatment of acute mania.

PMID- 29174865 TI - Deep brain stimulation induces antidepressant-like effects in serotonin transporter knockout mice. AB - BACKGROUND: Some of the antidepressant-like effects of ventromedial prefrontal cortex (vmPFC) deep brain stimulation (DBS) in rodents have been attributed to the modulation of prefrontal-raphe pathways. This is largely different from selective serotonin reuptake inhibitors (SSRIs), which increase serotonin (5-HT) levels by inhibiting the serotonin transporter (SERT). SSRIs have limited efficacy when given to SERT knockout (KO) mice, or patients with mutations in the serotonin transporter promoter gene (5-HTTLPR). HYPOTHESIS: vmPFC DBS will induce antidepressant-like effects and serotonin release in SERT KOs. RESULTS: DBS treated wild-type and SERT KO mice had a significant 22-26% decrease in immobility in the forced swim test. DBS delivered to either group was associated with 33-55% increase in 5-HT levels. CONCLUSIONS: DBS induced a significant antidepressant-like effect in KO mice. This suggests that it may be reasonable to consider DBS in states where SERT is not fully operational. PMID- 29174866 TI - Acute Myocardial Infarction Population Incidence and Mortality Rates, and 28-day Case-fatality in Older Adults. The REGICOR Study. AB - INTRODUCTION AND OBJECTIVES: Our aims were to determine acute myocardial infarction (AMI) incidence and mortality rates, and population and in-hospital case-fatality in the population older than 74 years; variability in clinical characteristics and AMI management of hospitalized patients, and changes in the incidence and mortality rates, case-fatality, and management by age groups from 1996 to 1997 and 2007 to 2008. METHODS: A population-based AMI registry in Girona (Catalonia, Spain) including individuals with suspected AMI older than 34 years. RESULTS: The incidence rate increased with age from 169 and 28 cases/100 000 per year in the group aged 35 to 64 years to 2306 and 1384 cases/100 000 per year in the group aged 85 to 94 years, in men and women, respectively. Population case fatality also increased with age, from 19% in the group aged 35 to 64 years to 84% in the group aged 85 to 94 years. A lower population case-fatality was observed in the second period, mainly explained by a lower in-hospital case fatality. The use of invasive procedures and effective drugs decreased with age but increased in the second period in all ages up to 84 years. CONCLUSIONS: Acute myocardial infarction incidence, mortality, and case-fatality increased exponentially with age. There is still a gap in the use of invasive procedures and effective drugs between younger and older patients. PMID- 29174867 TI - The synthesis of steroids by Taenia crassiceps WFU cysticerci and tapeworms is related to the developmental stages of the parasites. AB - Taeniids tapeworms are hermaphroditic helminths that gradually develop testis and ovaries in their reproductive units. The larval stage of the tapeworms named cysticercus is a vesicle that contains the scolex and proliferates asexually in the abdominal cavity of mice. Once in the host, they evaginate, attach to the gut and develop into an adult organism, the tapeworm. We have previously reported reported that T. crassiceps ORF and solium cysticerci transform steroid precursors to androgens and estrogens. Taenia crassiceps WFU cysticerci can also synthesize corticosteroids. The aim of the present work is to investigate the relationship between steroid synthesis ability and the developmental stage of the parasite T. crassiceps WFU. To this purpose, cysticerci were obtained from the abdominal cavity of female mice, manually separated in invaginated (IC) and evaginated parasites (EC) and preincubated for 24 h in DMEM plus antibiotics/antimycotics. Next step consisted in incubation for different periods in the fresh media added with tritiated androstenedione (3H-A4) or progesterone (3H-P4) and incubated for different periods. Taenia crassiceps WFU tapeworms were recovered from the intestine of golden hamsters that had been orally infected with cysticerci. The worms were pre-cultured in DMEM plus FBS and antibiotics, and then incubated without FBS for different time periods, in the presence of 3H A4 or 3H-P4. At the end of the experiments the media from cysticerci and tapeworms were analyzed by thin layer chromatography. Results showed that testosterone synthesis was significantly higher in the evaginated cysticerci and increased with time in culture. The invaginated and evaginated cysticerci also synthesized small quantities of 17beta-estradiol (E2) and estrone. The evaginated cysticerci synthesized twice more 3H-deoxycorticosterone (3H-DOC) than the invaginated parasites, the production increased significantly with time in culture. Taenia crassiceps WFU tapeworms synthesized significant quantities of 3H testosterone and small amounts of estrone after only 3 h of culture in the presence of 3H-A4. The tapeworms also transformed 3H-P4 to 3H-DOC and increased its synthesis after 24 h in culture. In summary, our data show the pathways that T. crassiceps WFU cysticerci use to synthesize sexual steroids in both larval developmental stages and reveals the steroidogenic capacity of the tapeworms. PMID- 29174868 TI - Expression of gonadotropin and sex steroid hormone receptor mRNA in the utero vaginal junction containing sperm storage tubules of oviduct during sexual maturation in Japanese quail. AB - Sex steroid hormones play an important role in reproductive tissue development of avian species. However, their role in Japanese quail is yet to be established. To understand the physiological role of hormones involved in the development of sperm storage tubules (SSTs) in quail, we investigated expression profiles of gonadotropin (LH-R and FSH-R) and sex steroid hormone (PR-R, ER-alpha and ER beta) receptors in the uterovaginal junction (UVJ) containing SSTs before and during sexual maturation i.e. four to eight weeks. Every week four birds were sacrificed to collect blood and UVJ for sex steroid hormone (progesterone and estrogen) estimation and gene expression profiling of sex steroid hormone (PR-R, ER-alpha and ER-beta) and gonadotropin receptors (LH-R and FSH-R) using qRT-PCR. Receptor expression results showed that the expression of sex steroid receptor (PR-R, ER-alpha and ER-beta) genes were upregulated significantly (P < .05) in SSTs with the advancement of age. The expression of gonadotropin receptors (LH-R and FSH-R) was only high at week 5 and 6 respectively. Serum hormone analysis indicated a significant (P < .05) rise in estradiol till 7th week and progesterone from 7th week onwards. These results suggest that the gonadotropin and sex steroid hormone receptors may have the role in the development and maintenance of UVJ that contains predominantly SSTs during sexual maturation. PMID- 29174869 TI - Expression characteristics of BMP2, BMPR-IA and Noggin in different stages of hair follicle in yak skin. AB - Bone morphogenetic protein 2 (BMP2), BMP receptor-IA (BMPR-IA), and the BMP2 antagonist Noggin are important proteins involved in regulating the hair follicle (HF) cycle in skin. In order to explore the expression profiles of BMP2, BMPR-IA, and Noggin in the HF cycle of yak skin, we collected adult yak skin in the telogen, proanagen, and midanagen phases of HFs and evaluated gene and protein expression by real-time quantitative polymerase chain reaction (qRT-PCR), western blotting, and immunohistochemistry. qRT-PCR and western blotting results showed that BMP2 and BMPR-IA expression levels were highest in the telogen of HFs and higher than that of Noggin in the same phase. The expression of Noggin was significantly higher in proanagen and midanagen phases of HFs than in the telogen phase, with the highest expression observed in the proanagen phase. Moreover, the expression of Noggin in the proanagen phase was significantly higher than those of BMP2 and BMPR-IA during the same phase. Immunohistochemistry results showed that BMP2, BMPR-IA, and Noggin were expressed in the skin epidermis, sweat glands, sebaceous glands, HF outer root sheath, and hair matrix. In summary, the characteristic expression profiles of BMP2, BMPR-IA, and Noggin suggested that BMP2 and BMPR-IA had inhibitory effects on the growth of HFs in yaks, whereas Noggin promoted the growth of yak HFs, mainly by affecting skin epithelial cell activity. These results provide a basis for further studies of HF development and cycle transition in yak skin. PMID- 29174870 TI - Molecular cloning, tissue distribution, and effect of fasting and refeeding on the expression of neuropeptide Y in Channa argus. AB - Neuropeptide Y (NPY) is a 36 amino-acid amidated peptide of the pancreatic polypeptide (PP) family, which plays an important role in appetite regulation and energy expenditure in mammals. Although several teleost NPY have been identified, its roles remain unclear in fish. We herein reported on the molecular cloning, tissue distribution and the effect of fasting on the expression of NPY in Channa argus, and designated as CaNPY. It consisted of a 300 bp open reading frame predicted to encode a prepro-NPY of 99 amino acids. Sequence analysis revealed that CaNPY was highly conserved (>60%) with other vertebrate NPY. Phylogenetic analysis highly supported CaNPY was closely related to piscine NPY. In addition, except for muscle and spleen tissues, CaNPY was found to extensively expressed in all other detected tissues, with the highest level in brain. Futhermore, the CaNPY transcript was found to significantly increase after short-term and long term food deprivation, and dramatically decrease following refeeding. These findings suggested that CaNPY might be involved in food intake regulation and it could be as a potential target locus to improve commercial production of this kind of fish. PMID- 29174871 TI - Resection of neurogenic heterotopic ossification (NHO) of the hip. AB - Neurogenic heterotopic ossification of the hip is secondary to neurologic lesions such as cranial trauma, stroke, medullary injury or cerebral anoxia. We shall not deal here with the other etiologies of heterotopic ossification. There are numerous locations within the hip, depending on etiology and relations with adjacent neurovascular structures are sometimes close. Preoperative work-up should include contrast-enhanced CT; scintigraphy is non-contributive. Indications for surgery are decided in a multidisciplinary team meeting, with a contract laying out expected functional gain. It is this contract that determines the extent of resection, without seeking complete resection, which would incur an increased risk of complications. The surgical approach and resection strategy depend on lesion location and any resulting neurovascular compression. The most common complications are infection and postoperative hematoma. No adjuvant treatments have demonstrated efficacy against recurrence. PMID- 29174872 TI - Monteggia injuries. AB - The Monteggia injury is defined as radial head dislocation with a fracture of the ulnar shaft. This combination should be sought routinely in patients with ulnar fractures, even when the displacement is small. The emergent management is simple, as reducing the ulnar fracture is usually sufficient to stabilise the radial head. Internal fixation of the ulna deserves to be widely used to fully stabilise the radial head. Irreducibility of the radial head at the acute stage may indicate an interposition, which requires open surgery on the joint. Radial head dislocation may occur even with minimal displacement of the ulnar fragment. Chronic Monteggia fractures are more challenging to treat and their outcomes are more variable. The radial head becomes irreducible after 2 to 3 weeks. When a simple surgical approach fails to ensure stable reduction, the most widely used method at present is open reduction of the radial head and proximal osteotomy of the ulnar shaft. Stability must be obtained intra-operatively. Without treatment, radial head dislocation may be well tolerated for several months or even years. In the long term, however, osteoarticular remodelling results in loss of joint congruence, pain and, eventually, osteoarthritis. Radiographs must therefore be obtained on an emergency basis and analysed with great care to avoid missing a Monteggia fracture. PMID- 29174873 TI - Oral Sex and Condom Use in a U.S. National Sample of Adolescents and Young Adults. AB - PURPOSE: The objective of this study was to examine correlates associated with condom use at the last oral sex, as well as oral sex behavior, among adolescents and young adults (AYAs) aged 15-24 years in the U.S. METHODS: Descriptive statistics, logistic regression, and multinomial logistic regression were conducted using data collected from 3,816 females and 3,520 males in the 2011 2015 National Survey of Family Growth. RESULTS: More than half of AYAs had engaged in oral sex with an opposite-sex partner. Most youth reported having at least one oral sex partner in the last 12 months, with 16% of females and 24% of males reporting two or more partners. Condom use at the last oral sex was quite low (8% for females and 9% for males). Black males (adjusted odds ratio [AOR] = 3.46), black females (AOR = 2.65), and females of other race/ethnicities (AOR = 2.40) were more likely to use a condom at the last oral sex. Females aged 20-24 years (AOR = .31), females whose mothers had a college education or more (AOR = .43), and males and females who reported no intercourse experience were less likely to use a condom at the last oral sex (AORs = .46 and .20, respectively). CONCLUSIONS: Our study suggests that oral sex with an opposite-sex partner is a normative behavior for AYAs; however, condom use during this sexual activity is uncommon. Interactive workshops and physician-patient discussions focused on the health risk risks associated with oral sex, as well as appropriate methods of protection, may help to increase condom uptake. PMID- 29174874 TI - Cervical Cancer Screening and Follow-Up Procedures in Women Age <21 Years Following New Screening Guidelines. AB - PURPOSE: The 2009 American College of Obstetricians and Gynecologists guidelines recommended no cervical cancer screening before age 21 years. We examined changes in screening, diagnostic, and treatment procedures for cervical dysplasia after guideline introduction, and cost implications. METHODS: We studied Davidson County women aged 18-20 years, enrolled in Tennessee Medicaid, 2006-2014. We identified those with at least one Papanicolaou (Pap) test, human papillomavirus detection test, colposcopy, or excisional dysplasia treatment annually via Current Procedural Terminology coding. We used rate ratios with 95% confidence intervals to compare annual changes in procedure and treatment rates from 2014 to 2006. We counted total outcomes to estimate annual costs based on 2014 average procedural costs. RESULTS: From 2006 to 2014, about 3,800 Davidson County women aged 18-20 years were enrolled in Medicaid annually. From 2006 to 2014, there were declines in Pap tests from 55.6 to 15.2 per 100 women (rate ratio .27, 95% confidence interval .25-.3); human papillomavirus tests from 13.8 to 5.9 per 100 (.42, .36-.5); colposcopy from 9.4 to 1.1 per 100 (.12, .08-.17); and dysplasia treatment from 1.1 to 0 per 100. The estimated cost of screening and procedures fell from $53 to $8 per enrolled woman, not accounting for changes in visits or complications associated with these procedures. CONCLUSIONS: The 2009 screening guidelines were associated with major declines in screening, diagnostic, and treatment procedures for cervical dysplasia. Minimum estimated procedure and treatment costs saved were $45 per enrolled woman age 18-20 years. PMID- 29174875 TI - Insights Into Aspects Behind Internet-Related Disorders in Adolescents: The Interplay of Personality and Symptoms of Adjustment Disorders. AB - PURPOSE: Problematic Internet use (PIU) that has recently been referred to as Internet-related disorder is a growing health concern. Yet, it is unclear why some adolescents are developing problematic use, whereas others sustain control. Based on previous research, we hypothesize that personality traits (low conscientiousness and high neuroticism) act as predispositions for PIU. We further hypothesize that PIU can be understood as a maladaptive reaction toward critical life events and that these maladaptive reactions are exacerbated by dysfunctional personality traits. METHODS: The study investigates the prevalence of distinct subtypes of PIU among a sample of adolescents (n = 1,489; 10-17 years). Personality traits (Big Five Inventory-10 [BFI-10]), perceived stress (Perceived Stress Scale 4 [PSS-4]), and their relations to PIU (Scale for the Assessment of Internet and Computer Game Addiction [AICA-S]) were examined. As novel research questions, associations between PIU and adjustment disorders (Adjustment Disorder-New Module [ADNM]-6) and the mediating role of personality were investigated. RESULTS: The prevalence of PIU was 2.5%; girls (3.0%) were more often affected than boys (1.9%). Social networking sites in girls and online games in boys were most often associated with PIU. Low conscientiousness and high neuroticism generally predicted PIU. Significantly more adolescents with PIU (70%) reported critical life events compared with those without PIU (42%). PIU was related to heightened stress and higher adjustment disorder symptoms. These associations were exacerbated by conscientiousness and neuroticism. CONCLUSIONS: Although the overall prevalence for PIU is in line with previous studies, it appeared unexpectedly that girls were affected more often than boys. Adjustment disorders and stress showed strong associations with PIU. This bears implications for adapting etiopathological assumptions and early intervention strategies. PMID- 29174876 TI - Ability of Nontraditional Risk Factors and Inflammatory Biomarkers for Cardiovascular Disease to Identify High Cardiometabolic Risk in Adolescents: Results From the LabMed Physical Activity Study. AB - PURPOSE: Then objective of this study was to evaluate the ability of several nontraditional cardiometabolic and inflammatory biomarkers in identifying high cardiometabolic risk in adolescents. METHODS: A cross-sectional study was conducted with 529 Portuguese adolescents (267 girls) aged 14.3 +/- 1.7 years. A clustered cardiometabolic risk score (body fat percentage, systolic blood pressure, ratio of total cholesterol to high-density lipoprotein cholesterol, triglycerides, homeostatic model assessment of insulin resistance, and negative values of cardiorespiratory fitness) was computed. The nontraditional cardiometabolic biomarkers assessed were complement factors (C3 and C4), C reactive protein (CRP), fibrinogen, leptin, white blood cells (WBCs), albumin, interleukin-6, and a clustered score of inflammatory biomarkers (InflaScore) (C3, C4, CRP, fibrinogen, and leptin). RESULTS: Receiver operating characteristic curves analyses showed that C3, C4, CRP, fibrinogen, leptin, and the InflaScore were able to present discriminatory ability in identifying an unfavorable cardiometabolic profile in both girls and boys (p <.01 for all). Logistic regression analyses showed that C3, C4, CRP, fibrinogen, leptin, the InflaScore (in both sexes), and WBC (boys) were associated with high cardiometabolic risk, independent of age, pubertal stage, socioeconomic status, or adherence to a Mediterranean diet (p <.05 for all). CONCLUSIONS: C3, C4, CRP, fibrinogen, and leptin were associated with high cardiometabolic risk in both sexes and WBC in boys. In addition, the clustered inflammatory biomarkers seem to have a better diagnostic accuracy in identifying an unfavorable cardiometabolic profile than single biomarkers. Such biomarkers may have utility in motivating health professionals, public health workers, and adolescents' families toward lifestyle changes, improving prevention efforts early in life. PMID- 29174877 TI - Cholinesterase Inhibitor Discontinuation: The Buck Stops Here. PMID- 29174879 TI - Spontaneous Cystic Arteriovenous Malformation-A Novel Treatment Alternative. AB - BACKGROUND: Brain arteriovenous malformation (BAVM) is a life-threatening vascular congenital malformation due to the risk of intracerebral hemorrhage. The formation of a spontaneous cyst within a BAVM, without history of hemorrhage or gamma knife surgery, is rare and has an unknown pathophysiology. We suggest a novel theory of spontaneous cystic BAVM formation, subsequently treated with endovascular embolization followed by surgery with a favorable long-term outcome. METHODS: Review of the literature using PUBMED database and comparison between clinical presentation, diagnostic imaging studies, and treatment options. RESULTS: The high flow causing a shear stress over the drainage vein may be responsible for venous ectasia and thus incrementing hydrostatic intranidal pressure causing a serous effusion that develops into a pseudocyst. We hypothesize that hemodynamic factors may be responsible for both origin and growth of such cystic lesions. CONCLUSIONS: Endovascular treatment allowed us to achieve cyst volume reduction by managing its unique flow characteristics. To our knowledge, this is the first case report of combined treatment with endovascular and surgical approach of a cystic BAVM. PMID- 29174878 TI - Utility of Fractional Anisotropy in Cerebral Peduncle for Stroke Outcome Prediction: Comparison of Hemorrhagic and Ischemic Strokes. AB - BACKGROUND: Diffusion-tensor fractional anisotropy (FA) has been used for predicting stroke outcome. However, most previous studies focused on patients with either hemorrhagic or ischemic stroke. The aim of this study was to assess the correlation between FA and outcome for patients with hemorrhagic stroke and those with ischemic stroke, and then compare their correlation patterns. METHODS: This study sampled 40 hemorrhagic and 40 ischemic stroke patients from our previously published reports. Diffusion-tensor images were obtained on days 14 21, and FA images were generated, after which the ratio of FA within the cerebral peduncles of the affected and unaffected hemispheres (rFA) was calculated. Outcome was assessed using Brunnstrom stage (BRS), motor component of the functional independence measure (FIM-motor), and total length of hospital stay (LOS) at discharge from our affiliated rehabilitation hospital. The data were then compared between the hemorrhage and the infarct groups. Correlation analyses between rFA and outcome assessments were performed separately for both groups and then were compared between the groups. RESULTS: The hemorrhage group exhibited significantly more severe BRS, longer LOS, and lower rFA than the infarct group. The correlations between rFA and outcome measures were all statistically significant for both the hemorrhage and the infarct groups. The correlation patterns for BRS and LOS were very similar between the hemorrhage and the infarct groups. However, such similarity was not evident for FIM-motor. CONCLUSIONS: FA in the cerebral peduncles may be used to predict extremity functions and LOS for both types of stroke.

PMID- 29174881 TI - Reprint of "Anti-therapeutic antibodies and their clinical impact in patients treated with the TNF antagonist adalimumab". AB - Patients treated with the TNF antagonist adalimumab develop anti-therapeutic antibodies (ATA), the prevalence of which varies depending on the assay used. Most assays are compromised due to the presence of adalimumab in the clinical samples. Our objective was to develop an antibody assay, applicable for clinical testing, which overcomes the limitation of therapeutic interference and to further determine the relationship between ATA development, adalimumab levels and disease activity in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) or ankylosing spondylitis (AS). Use of an electrochemiluminescence platform permitted development of fit-for-purpose immunoassays. Serum samples from patients, taken prior to and at 12 and 24 weeks of treatment, were retrospectively analysed for levels of adalimumab and ATA. Overall, the antibody prevalence was 43.6% at 12 weeks and 41% at 24 weeks of treatment. Disruption of immune complexes by acid dissociation, a strategy often adopted for this purpose, only marginally increased the antibody prevalence to 48.7% and 46% at 12 and 24 weeks respectively. We found that antibody formation was associated with decreasing levels of circulating adalimumab, but no direct effect on disease activity was evident as assessed using DAS28 for RA patients and BASDAI for PsA and AS patients. However, a negative correlation of free adalimumab trough levels with disease activity scores was observed. Data showed that adalimumab levels can serve as an indicator of ATA development which can then be confirmed by ATA testing. Monitoring of both therapeutic and antibodies should be considered during adalimumab therapy to allow clinicians to personalise treatments for maximal therapeutic outcomes. PMID- 29174882 TI - Optimizing intraoperative imaging during proximal femoral fracture fixation - a performance improvement program for surgeons. AB - INTRODUCTION: Formal training for surgeons regarding intraoperative imaging is lacking. This project investigated the effect of an educational intervention focusing on obtaining and assessing a standardized lateral view of the proximal femur during intramedullary nailing of a pertrochanteric fracture. MATERIALS AND METHODS: Anatomical landmarks of the proximal femur that can be identified using intraoperative fluoroscopy and criteria for image quality, i.e. quality of projection were defined in a consensus process, followed by the development of educational materials and a 7-item checklist. Five surgeons from 5 Trauma Centers in 4 countries participated. Each surgeon a) assessed 5 of their own retrospective cases and 5 retrospective cases from 4 colleagues from their clinic, b) viewed an educational video and poster and re-assessed the same cases, and c) assessed the intraoperative images of 5 prospectively collected consecutive cases of their own and of colleagues afterwards. RESULTS: The percentage of positive ratings for image quality increased from 72% prior to educational intervention to 88% after intervention (p<0.001), and number of "not assessable" images decreased significantly. Percentage agreement between surgeons on the assessments increased from 75% to 87%. The proportion of best possible ratings for fracture reduction and implant position increased from 58% to 72% and from 49% to 66%, respectively. Percentage agreement between surgeons on assessment of reduction and implant position increased. DISCUSSION AND CONCLUSIONS: A focused educational intervention can improve surgeons' ability to obtain and assess lateral view intraoperative images of the proximal femur and can improve the quality of reduction and implant positioning. PMID- 29174883 TI - Estimating abortion provision and abortion referrals among United States obstetrician-gynecologists in private practice. AB - OBJECTIVE: The objective was to examine the provision of abortion by obstetrician gynecologists in private practice in the United States (U.S.) and their willingness to provide referrals for abortion services. STUDY DESIGN: We conducted a cross-sectional national survey of 1961 U.S. obstetrician gynecologists to estimate the frequency with which abortions and referrals for abortion care were provided in private practice settings. Key measures included whether respondents had provided any abortions in 2013 or 2014, type of abortions provided and willingness to provide abortion referrals. Facility location by region was the only measured correlate of abortion provision. RESULTS: We received a total of 988 surveys for a response rate of 65%. Sixty-seven (7%) obstetrician-gynecologists reported providing at least one abortion in 2013 or 2014, though this result ranged from 4% (n=23) to 13% (n=44) of obstetrician gynecologists depending on survey response type. Among physicians practicing in the Northeast and West, 14% and 10%, respectively (n=24 in each region) were abortion providers compared to 4% (n=9) and 3% (n=10) of physicians in the Midwest and South, respectively. Twenty-three (42%) providers indicated only performing surgical abortions, 14 (25%) indicated only medication abortions, and 18 (33%) reported providing both. Among respondents who did not provide abortions, just over half (n=415, 54%) indicated that they referred patients to a facility or practice where they could obtain an abortion, but 271 (35%) said they would not provide a referral. CONCLUSIONS: Only a small proportion of all obstetrician-gynecologists in private practice settings provide abortions. Among nonproviders, a substantial minority do not offer abortion referrals. IMPLICATIONS: Particularly in geographic areas with few abortion providers, continued efforts are needed to equip medical professionals with information and training to make direct referrals. PMID- 29174884 TI - Preoperative progressive pneumoperitoneum in obese patients with loss of domain hernias. AB - BACKGROUND: Repair of hernias with loss of domain in obese patients can lead to acute respiratory failure. OBJECTIVES: The objective of this study was to analyze preoperative progressive pneumoperitoneum (PPP) in increasing abdominal cavity volume and its impact on respiratory function. SETTING: The study was conducted at the University Hospital, State University of Londrina, Brazil, which is a referral center for the treatment of obesity. The patients were hospitalized for the duration of the study. METHODS: Sixteen obese patients were evaluated. Computed tomography was used to determine hernia sac volume (HSV) and abdominal cavity volume (ACV). Respiratory function was evaluated by measuring vital capacity and forced expiratory volume in the first second (FEV-1). All data were obtained before PPP, on the day before surgery, and on the second postoperative day. PPP was performed daily with insufflation of CO2. RESULTS: The number of insufflations was 12. The average of total volume inflated was 5.7 L. The HSV was 2953 cm3 before PPP and 1935 cm3 after PPP. The average ACV increased from 8898 to 11,317 cm3 after PPP. The relationship between HSV and ACV was 38.2% before and 16.3% after PPP. There was a favorable improvement in respiratory function with an increase in vital capacity from 1875 to 2760 mL and an increase in FEV-1 from 1060 to 1670 mL after PPP. Respiratory function tests after surgery showed values of 2600 and 1560 mL, respectively, for cavity volume and FEV-1. There were no postoperative respiratory complications. CONCLUSIONS: This technique can be used safely in the surgical preparation of obese patients with hernias with loss of domain, reducing the relation between HSV and ACV and avoiding pulmonary complications. PMID- 29174885 TI - Assessing risk factors, presentation, and management of portomesenteric vein thrombosis after sleeve gastrectomy: a multicenter case-control study. AB - BACKGROUND: Portomesenteric vein thrombosis (PMVT) is a rare complication of laparoscopic sleeve gastrectomy. OBJECTIVES: To identify incidence, patient factors, diagnosis, and treatment of PMVT after laparoscopic sleeve gastrectomy in a large administrative data registry. SETTING: Academic Hospitals and Private Practices, United States. METHODS: A retrospective chart review of 5538 sleeve gastrectomy patients between January 1, 2008 and September 30, 2016 was performed at 5 bariatric centers in the United States. A total of 11 patients were identified as developing PMVT, and 3 controls for each patient were selected by matching age, sex, preoperative body mass index, and center. RESULTS: After adjusting for confounding variables, 2 patient factors significantly impacted the risk of PMVT after sleeve gastrectomy including personal history of malignancy (odds ratio 62, 95% confidence interval (CI) 1.4-99.9), and type 2 diabetes (odds ratio 12.7, 95% CI 1.2-137.3) compared with controls. Mean period from laparoscopic sleeve gastrectomy to presentation of PMVT was 19.3 +/- 15.11 days (range, 8-62). All patients except 1 complained of abdominal pain as the main presenting symptom. Other complaints included nausea and vomiting, no bowel movement, decreased appetite, diarrhea, and dehydration, and leukocytosis was present in 45.5% of the patients. All diagnoses were made by using computed tomography. All initial treatments were anticoagulation, heparin drip being the most common method (90.9%). Of patients, 9 (81.8%) required a secondary anticoagulation therapy, and 1 (9.1%) patient required a reoperation. CONCLUSION: Incidence of PMVT is low after sleeve gastrectomy. A personal history of malignancy and type 2 diabetes increase the risk of PMVT. Increasing abdominal pain in a context of dehydration is common presenting symptoms with diagnosis confirmed by computed tomography. Anticoagulation is the standard treatment. There was no mortality associated with the occurrence of PMVT in this cohort. PMID- 29174886 TI - A New Lineage of Eukaryotes Illuminates Early Mitochondrial Genome Reduction. AB - The origin of eukaryotic cells represents a key transition in cellular evolution and is closely tied to outstanding questions about mitochondrial endosymbiosis [1, 2]. For example, gene-rich mitochondrial genomes are thought to be indicative of an ancient divergence, but this relies on unexamined assumptions about endosymbiont-to-host gene transfer [3-5]. Here, we characterize Ancoracysta twista, a new predatory flagellate that is not closely related to any known lineage in 201-protein phylogenomic trees and has a unique morphology, including a novel type of extrusome (ancoracyst). The Ancoracysta mitochondrion has a gene rich genome with a coding capacity exceeding that of all other eukaryotes except the distantly related jakobids and Diphylleia, and it uniquely possesses heterologous, nucleus-, and mitochondrion-encoded cytochrome c maturase systems. To comprehensively examine mitochondrial genome reduction, we also assembled mitochondrial genomes from picozoans and colponemids and re-annotated existing mitochondrial genomes using hidden Markov model gene profiles. This revealed over a dozen previously overlooked mitochondrial genes at the level of eukaryotic supergroups. Analysis of trends over evolutionary time demonstrates that gene transfer to the nucleus was non-linear, that it occurred in waves of exponential decrease, and that much of it took place comparatively early, massively independently, and with lineage-specific rates. This process has led to differential gene retention, suggesting that gene-rich mitochondrial genomes are not a product of their early divergence. Parallel transfer of mitochondrial genes and their functional replacement by new nuclear factors are important in models for the origin of eukaryotes, especially as major gaps in our knowledge of eukaryotic diversity at the deepest level remain unfilled. PMID- 29174887 TI - Fbxl4 Serves as a Clock Output Molecule that Regulates Sleep through Promotion of Rhythmic Degradation of the GABAA Receptor. AB - The timing of sleep is tightly governed by the circadian clock, which contains a negative transcriptional feedback loop and synchronizes the physiology and behavior of most animals to daily environmental oscillations. However, how the circadian clock determines the timing of sleep is largely unclear. In vertebrates and invertebrates, the status of sleep and wakefulness is modulated by the electrical activity of pacemaker neurons that are circadian regulated and suppressed by inhibitory GABAergic inputs. Here, we showed that Drosophila GABAA receptors undergo rhythmic degradation in arousal-promoting large ventral lateral neurons (lLNvs) and their expression level in lLNvs displays a daily oscillation. We also demonstrated that the E3 ligase Fbxl4 promotes GABAA receptor ubiquitination and degradation and revealed that the transcription of fbxl4 in lLNvs is CLOCK dependent. Finally, we demonstrated that Fbxl4 regulates the timing of sleep through rhythmically reducing GABA sensitivity to modulate the excitability of lLNvs. Our study uncovered a critical molecular linkage between the circadian clock and the electrical activity of pacemaker neurons and demonstrated that CLOCK-dependent Fbxl4 expression rhythmically downregulates GABAA receptor level to increase the activity of pacemaker neurons and promote wakefulness. PMID- 29174888 TI - Trans-endocytosis of Planar Cell Polarity Complexes during Cell Division. AB - To coordinate epithelial architecture with proliferation, cell polarity proteins undergo extensive remodeling during cell division [1-3]. A dramatic example of polarity remodeling occurs in proliferative basal cells of mammalian epidermis whereupon cell division, transmembrane planar cell polarity (PCP) proteins are removed from the cell surface via bulk endocytosis [4]. PCP proteins form intercellular complexes, linked by Celsr1-mediated homophilic adhesion, that coordinate polarity non-autonomously between cells [5, 6]. Thus, the mitotic reorganization of PCP proteins must alter not only proteins intrinsic to the dividing cell but also their interacting partners on neighboring cells. Here, we show that intercellular Celsr1 complexes that connect dividing cells with their neighbors remain intact during mitotic internalization, resulting in an uptake of Celsr1 protein from interphase neighbors. Trans-internalized Celsr1 carries with it additional core PCP proteins, including the posteriorly enriched Fz6 and anteriorly enriched Vangl2. Cadherin-mediated homophilic adhesion is necessary for trans-endocytosis, and adhesive junctional PCP complexes appear to be destined for degradation upon internalization. Surprisingly, whereas Fz6 and Vangl2 both internalize in trans, Vangl2 proteins intrinsic to the dividing cell remain associated with the plasma membrane. Persistent Vangl2 stabilizes Celsr1 and impedes its internalization, suggesting that dissociation of Vangl2 from Celsr1 is a prerequisite for Celsr1 endocytosis. These results demonstrate an unexpected transfer of PCP complexes between neighbors and suggest that the Vangl2 population that persists at the membrane during cell division could serve as an internal cue for establishing PCP in new daughter cells. PMID- 29174889 TI - Homing Ants Get Confused When Nest Cues Are Also Route Cues. AB - The desert ant Cataglyphis fortis inhabits the salt pans of Tunisia. Individual ants leave the nest for foraging trips that can cover distances of more than 1,500 m [1]. Homing ants use path integration [2, 3], but they also rely on visual [4] and olfactory [5] nest-defining cues to locate the nest entrance. However, nest cues can become ambiguous when they are ubiquitous in the environment. Here we show how ants behave during the nest search when the same cues occur at the nest and along the route. Homing ants focused their search narrowly around a visual or olfactory cue that in training they had experienced only at the nest. However, when ants were trained to the same cue not only at the nest but also repeatedly along the foraging route, they later exhibited a less focused search around the cue. This uncertainty was eliminated when ants had a composite cue at the nest that consisted of two components, one unique to the nest and another that also occurred along the route. Here, the ants focused their search on that part of the binary blend that was presented only at the nest and ignored the other, ubiquitous component. Ants thus not only seem to be able to pinpoint their nest by following learned visual and olfactory cues, but also take into account which cues uniquely specify the nest and which, due to their ubiquity, are less informative and so less reliable. VIDEO ABSTRACT. PMID- 29174890 TI - Learning Biases Underlie "Universals" in Avian Vocal Sequencing. AB - Biological predispositions in vocal learning have been proposed to underlie commonalities in vocal sequences, including for speech and birdsong, but cultural propagation could also account for such commonalities [1-4]. Songbirds such as the zebra finch learn the sequencing of their acoustic elements ("syllables") during development [5-8]. Zebra finches are not constrained to learn a specific sequence of syllables, but significant consistencies in the positioning and sequencing of syllables have been observed between individuals within populations and between populations [8-10]. To reveal biological predispositions in vocal sequence learning, we individually tutored juvenile zebra finches with randomized and unbiased sequences of syllables and analyzed the extent to which birds produced common sequences. In support of biological predispositions, birds tutored with randomized sequences produced songs with striking similarities. Birds preferentially started and ended their song sequence with particular syllables, consistently positioned shorter and higher frequency syllables in the middle of their song, and sequenced their syllables such that pitch alternated across adjacent syllables. These patterns are reminiscent of those observed in normally tutored birds, suggesting that birds "creolize" aberrant sequence inputs to produce normal sequence outputs. Similar patterns were also observed for syllables that were not used for tutoring (i.e., unlearned syllables), suggesting that motor biases could contribute to sequence learning biases. Furthermore, zebra finches spontaneously produced acoustic patterns that are commonly observed in speech and music, suggesting that sensorimotor processes that are shared across a wide range of vertebrates could underlie these patterns in humans. PMID- 29174891 TI - Local Signals in Mouse Horizontal Cell Dendrites. AB - The mouse retina contains a single type of horizontal cell, a GABAergic interneuron that samples from all cone photoreceptors within reach and modulates their glutamatergic output via parallel feedback mechanisms. Because horizontal cells form an electrically coupled network, they have been implicated in global signal processing, such as large-scale contrast enhancement. Recently, it has been proposed that horizontal cells can also act locally at the level of individual cone photoreceptors. To test this possibility physiologically, we used two-photon microscopy to record light stimulus-evoked Ca2+ signals in cone axon terminals and horizontal cell dendrites as well as glutamate release in the outer plexiform layer. By selectively stimulating the two mouse cone opsins with green and UV light, we assessed whether signals from individual cones remain isolated within horizontal cell dendritic tips or whether they spread across the dendritic arbor. Consistent with the mouse's opsin expression gradient, we found that the Ca2+ signals recorded from dendrites of dorsal horizontal cells were dominated by M-opsin and those of ventral horizontal cells by S-opsin activation. The signals measured in neighboring horizontal cell dendritic tips varied markedly in their chromatic preference, arguing against global processing. Rather, our experimental data and results from biophysically realistic modeling support the idea that horizontal cells can process cone input locally, extending the classical view of horizontal cell function. Pharmacologically removing horizontal cells from the circuitry reduced the sensitivity of the cone signal to low frequencies, suggesting that local horizontal cell feedback shapes the temporal properties of cone output.

AB - The terminal stages of neuronal degeneration and death in neurodegenerative diseases remain elusive. Autophagy is an essential catabolic process frequently failing in neurodegeneration. Selective autophagy routes have recently emerged, including nucleophagy, defined as degradation of nuclear components by autophagy. Here, we show that, in a mouse model for the polyglutamine disease dentatorubral pallidoluysian atrophy (DRPLA), progressive acquirement of an ataxic phenotype is linked to severe cerebellar cellular pathology, characterized by nuclear degeneration through nucleophagy-based LaminB1 degradation and excretion. We find that canonical autophagy is stalled in DRPLA mice and in human fibroblasts from patients of DRPLA. This is evidenced by accumulation of p62 and downregulation of LC3-I/II conversion as well as reduced Tfeb expression. Chronic autophagy blockage in several conditions, including DRPLA and Vici syndrome, an early-onset autolysosomal pathology, leads to the activation of alternative clearance pathways including Golgi membrane-associated and nucleophagy-based LaminB1 degradation and excretion. The combination of these alternative pathways and canonical autophagy blockade, results in dramatic nuclear pathology with disruption of the nuclear organization, bringing about terminal cell atrophy and degeneration. Thus, our findings identify a novel progressive mechanism for the terminal phases of neuronal cell degeneration and death in human neurodegenerative diseases and provide a link between autophagy block, activation of alternative pathways for degradation, and excretion of cellular components. PMID- 29174893 TI - The Stone Age Plague and Its Persistence in Eurasia. AB - Yersinia pestis, the etiologic agent of plague, is a bacterium associated with wild rodents and their fleas. Historically it was responsible for three pandemics: the Plague of Justinian in the 6th century AD, which persisted until the 8th century [1]; the renowned Black Death of the 14th century [2, 3], with recurrent outbreaks until the 18th century [4]; and the most recent 19th century pandemic, in which Y. pestis spread worldwide [5] and became endemic in several regions [6]. The discovery of molecular signatures of Y. pestis in prehistoric Eurasian individuals and two genomes from Southern Siberia suggest that Y. pestis caused some form of disease in humans prior to the first historically documented pandemic [7]. Here, we present six new European Y. pestis genomes spanning the Late Neolithic to the Bronze Age (LNBA; 4,800 to 3,700 calibrated years before present). This time period is characterized by major transformative cultural and social changes that led to cross-European networks of contact and exchange [8, 9]. We show that all known LNBA strains form a single putatively extinct clade in the Y. pestis phylogeny. Interpreting our data within the context of recent ancient human genomic evidence that suggests an increase in human mobility during the LNBA, we propose a possible scenario for the early spread of Y. pestis: the pathogen may have entered Europe from Central Eurasia following an expansion of people from the steppe, persisted within Europe until the mid-Bronze Age, and moved back toward Central Eurasia in parallel with human populations. PMID- 29174894 TI - Disruption of Perceptual Learning by a Brief Practice Break. AB - Some forms of associative learning require only a single experience to create a lasting memory [1, 2]. In contrast, perceptual learning often requires extensive practice within a day for performance to improve across days [3, 4]. This suggests that the requisite practice for durable perceptual learning is integrated throughout each day. If the total amount of daily practice is the only important variable, then a practice break within a day should not disrupt across day improvement. To test this idea, we trained human listeners on an auditory frequency-discrimination task over multiple days and compared the performance of those who engaged in a single continuous practice session each day [4] with those who were given a 30-min break halfway through each practice session. Continuous practice yielded significant perceptual learning [4]. In contrast, practice with a rest break led to no improvement, indicating that the integration process had decayed within 30 min. In a separate experiment, a 30-min practice break also disrupted durable learning on a non-native phonetic classification task. These results suggest that practice trials are integrated up to a learning threshold within a transient memory store before they are sent en masse into a memory that lasts across days. Thus, the oft cited benefits of distributed over massed training [5, 6] may arise from different mechanisms depending on whether the breaks occur before or after a learning threshold has been reached. Trial integration could serve as an early gatekeeper to plasticity, helping to ensure that longer-lasting changes are only made when deemed worthwhile. PMID- 29174896 TI - Kinetic and thermodynamic analysis of dilute acid hydrolysis of sugarcane bagasse. AB - This study has investigated kinetic and thermodynamic features of dilute acid (2% v/v H2SO4, 1:30 w/v) hydrolysis of sugarcane bagasse. Time profiles of xylose formation in range of 100 degrees -130 degrees C and treatment period of 0-120 min have been analysed with modified biphasic Saeman model. Generation of glucose, arabinose and inhibitory products (furfural, 5-HMF and acetic acid) have also been analysed. Easy-to-hydrolyse fraction of hemicellulose increased with temperature. Activation energies for hydrolysis and xylose degradation were 60.3 and 83.4 kJ/mol, respectively. Although maximum xylose yield (0.81 g/g hemicellulose) was obtained at 130 degrees C, significant fraction of xylose was converted to inhibitory products. Thermodynamic analysis revealed DeltaH = 57.06 kJ/mol and DeltaS = -1.05 kJ/mol for hydrolysis. Moreover, xylose formation is thermodynamically more favoured (DeltaG = 468.53 kJ/mol) than degradation (DeltaG = 482.17 kJ/mol). Optimum conditions for hydrolysis are: temperature = 120 degrees C, time = 30 min, xylose yield = 0.76 g/g hemicellulose. PMID- 29174895 TI - A Peptide Signaling System that Rapidly Enforces Paternity in the Aedes aegypti Mosquito. AB - Female Aedes aegypti mosquitoes typically mate only once with one male in their lifetime, a behavior known as "monandry" [1]. This single mating event provisions the female with sufficient sperm to fertilize the >500 eggs she will produce during her ~4- to 6-week lifespan in the laboratory [2]. Successful mating induces lifetime refractoriness to subsequent insemination by other males, enforcing the paternity of the first male [3-5]. Ae. aegypti mate in flight near human hosts [6], and females become refractory to remating within seconds [1, 3, 4], suggesting the existence of a rapid mechanism to prevent female remating. In this study, we implicate HP-I, an Aedes- and male-specific peptide transferred to females [7], and its cognate receptor in the female, NPYLR1 [8], in rapid enforcement of paternity. HP-I mutant males were ineffective in enforcing paternity when a second male was given access to the female within 1 hr. NPYLR1 mutant females produced mixed paternity offspring at high frequency, indicating acceptance of multiple mates. Synthetic HP-I injected into wild-type, but not NPYLR1 mutant, virgins reduced successful matings. Asian tiger mosquito (Ae. albopictus) HP-I peptides potently activated Ae. aegypti NPYLR1. Invasive Ae. albopictus males are known to copulate with and effectively sterilize Ae. aegypti females by causing them to reject future mates [9]. Cross-species transfer of sperm and active seminal fluid proteins including HP-I may contribute to this phenomenon. This signaling system promotes rapid paternity enforcement within Ae. aegypti but may promote local extinction in areas where they compete with Ae. albopictus. PMID- 29174897 TI - Improving the methane yield of maize straw: Focus on the effects of pretreatment with fungi and their secreted enzymes combined with sodium hydroxide. AB - In order to improve the methane yield, the alkaline and biological pretreatments on anaerobic digestion (AD) were investigated. Three treatments were tested: NaOH, biological (enzyme and fungi), and combined NaOH with biological. The maximum reducing sugar concentrations were obtained using Enzyme T (2.20 mg/mL) on the 6th day. The methane yield of NaOH + Enzyme A was 300.85 mL/g TS, 20.24% higher than the control. Methane yield obtained from Enzyme (T + A) and Enzyme T pretreatments were 277.03 and 273.75 mL/g TS, respectively, which were as effective as 1% NaOH (276.16 mL/g TS) in boosting methane production, and are environmentally friendly and inexpensive biological substitutes. Fungal pretreatment inhibited methane fermentation of maize straw, 15.68% was reduced by T + A compared with the control. The simultaneous reduction of DM, cellulose and hemicellulose achieved high methane yields. This study provides important guidance for the application of enzymes to AD from lignocellulosic agricultural waste. PMID- 29174898 TI - Effect of aeration interval on oxygen consumption and GHG emission during pig manure composting. AB - To verify the optimal aeration interval for oxygen supply and consumption and investigate the effect of aeration interval on GHG emission, reactor-scale composting was conducted with different aeration intervals (0, 10, 30 and 50 min). Although O2 was sufficiently supplied during aeration period, it could be consumed to <10 vol% only when the aeration interval was 50 min, indicating that an aeration interval more than 50 min would be inadvisable. Compared to continuous aeration, reductions of the total CH4 and N2O emissions as well as the total GHG emission equivalent by 22.26-61.36%, 8.24-49.80% and 12.36-53.20%, respectively, was achieved through intermittent aeration. Specifically, both the total CH4 and N2O emissions as well as the total GHG emission equivalent were inversely proportional to the duration of aeration interval (R2 > 0.902), suggesting that lengthening the duration of aeration interval to some extent could effectively reduce GHG emission. PMID- 29174899 TI - The potential of tailoring the conditions of steam explosion to produce xylo oligosaccharides from sugarcane bagasse. AB - In this study, the potential of the steam explosion (SE) method to produce high levels XOS from sugarcane bagasse, a xylan-rich hemicellulosic feedstock, was assessed. The effect of different operating conditions on XOS production yield and selectivity were investigated using a mini-pilot scale SE unit. The results show that even under a non-optimized condition (190 degrees C, 5 min and 0.5% H2SO4 as catalyst), SE led to about 40% xylan recovery as XOS, which was comparable to the well-known, multi-step, enzymatic production of XOS from alkaline-extracted xylan, and other commonly employed chemical methods. In addition, the XOS-rich hydrolysate from SE constituted of greater diversity in the degree of polymerization, which has been shown to be desirable for prebiotic application. PMID- 29174900 TI - Co-combustion of sewage sludge and coffee grounds under increased O2/CO2 atmospheres: Thermodynamic characteristics, kinetics and artificial neural network modeling. AB - (Co-)combustion characteristics of sewage sludge (SS), coffee grounds (CG) and their blends were quantified under increased O2/CO2 atmosphere (21, 30, 40 and 60%) using a thermogravimetric analysis. Observed percentages of CG mass loss and its maximum were higher than those of SS. Under the same atmospheric O2 concentration, both higher ignition and lower burnout temperatures occurred with the increased CG content. Results showed that ignition temperature and comprehensive combustion index for the blend of 60%SS-40%CG increased, whereas burnout temperature and co-combustion time decreased with the increased O2 concentration. Artificial neural network was applied to predict mass loss percent as a function of gas mixing ratio, heating rate, and temperature, with a good agreement between the experimental and ANN-predicted values. Activation energy in response to the increased O2 concentration was found to increase from 218.91 to 347.32 kJ.mol-1 and from 218.34 to 340.08 kJ.mol-1 according to the Kissinger Akahira-Sunose and Flynn-Wall-Ozawa methods, respectively. PMID- 29174901 TI - Characterization of diversified Sb(V)-reducing bacterial communities by various organic or inorganic electron donors. AB - This study aims to enrich Sb(V)-reducing bacterial communities from Sb contaminated soils using various electron donors for bioremediation of Sb contaminated sites and recovery of Sb from wastewater. When the organic electron donors were used, Sb(V) reduction rates were 2-24 times faster but electron recoveries were 24-59% lower compared to the culture using inorganic electron donor. The morphological crystallizations of the antimony-reduced precipitates were completely different depending on the electron donor. Different microbial populations were enriched with various electron donors but most commonly, only Proteobacteria and Firmicutes phyla were enriched from a diversified soil microbial community. Geobacter sp. seemed to be an important bacterium in organic electron donors-fed cultures whereas an unclassified Rhodocyclaceae was dominant in inorganic electron donor-fed cultures. The results indicated that organic electron donors especially sugar groups were preferable options to obtain rapid Sb(V)-reduction whereas inorganic electron donor like H2 was better option to achieve high electron recovery. PMID- 29174902 TI - Antibiotic degradation and microbial community structures during acidification and methanogenesis of swine manure containing chlortetracycline or oxytetracycline. AB - Anaerobic digestion (AD) has been applied to animal manure stabilization, and antibiotics is frequently found in animal manure. However, antibiotic degradation and microbial community structures during two-stage AD (acidification and methanogenesis) remain poorly understood. This experiments on two-stage anaerobic swine manure digesters were performed to investigate the degradation mechanisms and effects of chlortetracycline (CTC) and oxytetracycline (OTC) on microbial community structures. Results showed that acidification and methanogenesis showed good degradation performance for manure containing CTC and OTC at 60 and 40 mg/kg.TS, respectively. CTC and OTC were degraded by 59.8% and 41.3% in the acidogenic stage and by 76.3% and 78.3% in the methanogenic stage, respectively. CTC and OTC negatively affected bacterial community in methanogenic and acidogenic stages, respectively. They also adversely influenced the archaeal species in the methanogenic stage. Two-stage AD was proposed to treat manure containing antibiotics and to reduce the negative effects of antibiotics on AD.

AB - The mixture of Eucalyptus globulus wood (EGW) and cheese whey powder (CWP) was proposed for intensification of simultaneous saccharification and fermentation (SSF) at high temperature and solid loadings using the industrial Saccharomyces cerevisiae Ethanol Red(r) strain. High ethanol concentration (93 g/L), corresponding to 94% ethanol yield, was obtained at 35 degrees C from 37% of solid mixture using cellulase and beta-galactosidase enzymes (24.2 FPU/g and 20.0 U/g, respectively). The use of CWP mixed with pretreated EGW increased the ethanol concentration in 1.5-fold, in comparison with SSF experiments without CWP for both Ethanol Red(r) and CEN.PK113-7D strains. Moreover, 1.4-fold higher ethanol concentration was obtained with Ethanol Red(r), in comparison with CEN.PK113-7D strain. Ethanol Red(r) strain was genetically engineered for beta galactosidase production in order to advance towards a fully integrated process. This work shows the feasibility of attaining high ethanol concentrations in second generation bioprocesses by a multi-waste valorization approach. PMID- 29174904 TI - Enhanced effects of maghemite nanoparticles on the flocculent sludge wasted from a high-rate anammox reactor: Performance, microbial community and sludge characteristics. AB - Magnetic nanoparticles (NPs) have been widely applied in environmental remediation, biomass immobilization and wastewater treatment, but their potential impact on anaerobic ammonium oxidation (anammox) biomass remains unknown. In this study, the short-term and long-term impacts of maghemite NPs (MHNPs) on the flocculent sludge wasted from a high-rate anammox reactor were investigated. Batch assays showed that the presence of MHNPs up to 200 mg L-1 did not affect anammox activity, reactive oxygen species production, or cell membrane integrity. Moreover, long-term addition of 1-200 mg L-1 MHNPs had no adverse effects on reactor performance. Notably, the specific anammox activity, the abundance of hydrazine synthase structural genes and the content of extracellular polymeric substance were increased with elevated MHNP concentrations. Meanwhile, the community structure was shifted to higher abundance of Candidatus Kuenenia indicated by high-throughput sequencing. Therefore, MHNPs could be applied to enhance anammox flocculent sludge due to their favorable biocompatibility. PMID- 29174905 TI - Enzymatic hydrolysis of cactus pear varieties with high solids loading for bioethanol production. AB - The optimization of enzymatic hydrolysis, with high solids loading, of two species of cactus pear for bioethanol production was tested evaluating the influence of surfactant Tween 80 and pretreatment with H2O and H2SO4 (1% v/v) (50 degrees C, 150 rpm, 3 h). XRD and FTIR analyzes were performed. Afterwards, the influence of the factors cellulase (FPU g-1), pectinase (U g-1) and solids load (% w/v), on the hydrolysis of varieties (50 degrees C, 150 rpm, 48 h), and the fermentation of the optimal point (33 degrees C, 8 h) were evaluated. The pretreatments and the Tween 80 did not increase the hydrolysis yields and Rotacional Central Compound Design indicated that the pectinase factor was not significant. The best cellulase and solids load conditions were 10 FPU g-1 of biomass and 30% w/v for both species. The fermentation efficiency of hydrolysates for Nopalea cochenillifera and Opuntia ficus-indica were 76.3% and 82.8%, respectively, showing their potential for bioethanol production. PMID- 29174906 TI - Novel anaerobic membrane bioreactor (AnMBR) design for wastewater treatment at long HRT and high solid concentration. AB - Performance of two novel designed anaerobic membrane bioreactor (AnMBRs) for wastewater treatment at long hydraulic retention time (HRT, 47 days) and high sludge concentration (22 g.L-1) was investigated. Results showed steady chemical oxygen demand (COD) removal (>98%) and mean biogas generation of 0.29 LCH4.g 1COD. Average permeates flux of 58.70 L.m-2.h-1 and 54.00 L.m-2.h-1 were achieved for reactors A and B, respectively. On top of reactor configuration, long HRT caused biofilm reduction by heterotrophic bacteria Chloroflexi resulting in high membrane flux. Mean total membrane resistances (2.23 * 109 m-1) and fouling rates (4.00 * 108 m-1.day-1) of both reactors were low suggesting better membrane fouling control ability of both AnMBRs. Effluent quality analysis showed the effluent soluble microbial products (SMP) were dominated by proteins compared to carbohydrates, and specific ultraviolet absorbance (SUVA) analysis revealed effluent from both reactors had low aromaticity with SUVA < 1 (L.mg-1.m-1) except for the first ten days. PMID- 29174907 TI - The influence of complex fermentation broth on denitrification of saline sewage in constructed wetlands by heterotrophic nitrifying/aerobic denitrifying bacterial communities. AB - An experimental vertical-flow constructed wetland (CW) was tested to treat salt containing sewage. CW clogging deposits and withered Pontederia cordata L. were collected into a complex fermentation broth to serve as the carbon source and its effects on the denitrification capacity and microbial composition of the CW were examined. Addition of the complex fermentation broth into the CW influent (1.8% salinity) led to high removal efficiencies of NH4+-N > 99.82 +/- 0.00% and TN > 90.39 +/- 0.05%. Heterotrophic nitrifiers and aerobic denitrifiers were entirely dominant in the middle and upper layers of the CW, where obligate halophilic, aerobic denitrifiers Zobellella occurred. The CW successfully cultivated and enriched heterotrophic nitrifying-aerobic denitrifying bacteria, overcoming the effects of salinity and insufficient organic carbon sources on the denitrification capacity of CW. This type of complex carbon sources can also facilitate the utilization of waste resources, such as CW clogging deposits and withered wetland plants. PMID- 29174908 TI - Integrated bioethanol production to boost low-concentrated cellulosic ethanol without sacrificing ethanol yield. AB - Four integrated designs were proposed to boost cellulosic ethanol titer and yield. Results indicated co-fermentation of corn flour with hydrolysate liquor from saccharified corn stover was the best integration scheme and able to boost ethanol titers from 19.9 to 123.2 g/L with biomass loading of 8% and from 36.8 to 130.2 g/L with biomass loadings of 16%, respectively, while meeting the minimal ethanol distillation requirement of 40 g/L and achieving high ethanol yields of above 90%. These results indicated integration of first and second generation ethanol production could significantly accelerate the commercialization of cellulosic biofuel production. Co-fermentation of starchy substrate with hydrolysate liquor from saccharified biomass is able to significantly enhance ethanol concentration to reduce energy cost for distillation without sacrificing ethanol yields. This novel method could be extended to any pretreatment of biomass from low to high pH pretreatment as demonstrated in this study.

AB - Liquid Biphasic Flotation (LBF) is an advanced recovery method that has been effectively applied for biomolecules extraction. The objective of this investigation is to incorporate the fermentation and extraction process of lipase from Burkholderia cepacia using flotation system. Initial study was conducted to compare the performance of bacteria growth and lipase production using flotation and shaker system. From the results obtained, bacteria shows quicker growth and high lipase yield via flotation system. Integration process for lipase separation was investigated and the result showed high efficiency reaching 92.29% and yield of 95.73%. Upscaling of the flotation system exhibited consistent result with the lab-scale which are 89.53% efficiency and 93.82% yield. The combination of upstream and downstream processes in a single system enables the acceleration of product formation, improves the product yield and facilitates downstream processing. This integration system demonstrated its potential for biomolecules fermentation and separation that possibly open new opportunities for industrial production.

AB - Many studies have described the dynamic modulation of corticospinal excitability of the prime movers during motor preparation. However although anticipatory postural adjustments (APA) are an inherent part of most voluntary movements, investigation of trunk muscle corticospinal excitability during motor preparation has been neglected in the literature. In the present study, the corticospinal excitability of the superficial multifidus (sMF) and rectus abdominis (RA) muscle has been assessed during the preparation of rapid arm flexions and extensions in fifteen participants. A Warning signal informed participants to prepare to move prior to a Go signal. Transcranial magnetic stimulation was applied during baseline and at 6 time intervals before (Delay period) or after (Motor execution period) the Go signal. Results revealed a significant inhibition of the amplitude of sMF motor-evoked potentials in both flexion and extension movements within the Delay period compared to baseline, while no significant modulation was observed for RA. During the Motor Execution period for arm extension, sMF displayed even more inhibition, along with a large and significant facilitation of RA. During the Motor execution period for arm flexion, sMF presented a trend toward larger motor-evoked potential amplitude compared to Delay period. These results suggest the existence of two concurrent mechanisms underlying motor preparation for APA: (i) before the Go signal, a nonspecific inhibitory mechanism for sMF, likely to preclude motor program release; (ii) after the Go signal, a task-specific modulation of corticospinal excitability consistent with the EMG pattern during the early phase of movement.

AB - Most investigators use a single treatment such as water deprivation or dietary sodium deficiency to evaluate thirst or sodium appetite, which underlie behavioral responses to body fluid challenges. The goal of the present experiments was to assess the effects of combined treatments in driving behaviors. Therefore, we evaluated the effect of combined overnight water deprivation and dietary sodium deficiency on water intake and salt intake by adult male rats in 2-bottle (0.5M NaCl and water) tests. Overnight water deprivation alone increased water intake, and 10days of dietary sodium deficiency increased 0.5M NaCl intake, with a secondary increase in water intake. During combined water deprivation and dietary sodium deficiency, water intake was enhanced and 0.5M NaCl was reduced, but not eliminated, suggesting that physiologically relevant behavioral responses persist. Nonetheless, the pattern of fluid intake was altered by the combined treatments. We also assessed the effect of these behaviors on induced deficits in body sodium and fluid volume during combined treatments and found that, regardless of treatment, fluid ingestion partially repleted the induced deficits. Finally, we examined urine volume and sodium excretion during dietary sodium deficiency with or without overnight water deprivation and found that, whether or not rats were water deprived, and regardless of water consumption, sodium excretion was minimal. Thus, the combination of water deprivation and dietary sodium deficiency appears to arouse drives that stimulate compensatory behavioral responses. These behaviors, in conjunction with physiological adaptations to the treatments, underlie body sodium and volume repletion in the face of combined water deprivation and dietary sodium deficiency.

AB - Cordycepin, an adenosine analogue, has been reported to improve cognitive function. Important roles on learning and memory of adenosine and its receptors, such as adenosine A1 and A2A receptors (A1R and A2AR), also have been shown. Therefore, we assume that the improvement of learning and memory induced by cordycepin is likely related to hippocampal adenosine content and adenosine receptor density. Here we investigated the effects of cordycepin on the short term spatial memory by using a spontaneous alternation behavior (SAB) test in Y maze, and then examined hippocampal adenosine content and A1R and A2AR densities. We found that orally administrated cordycepin (at dosages of 5 and 10mg/kg twice daily for three weeks) significantly increased the percent of relative alternation of mice in SAB but not altered body weight, hippocampus weight and hippocampal adenosine content. Furthermore, cordycepin decreased A2AR density in hippocampal subareas; however, cordycepin only reduced the A1R density in DG but not CA1 or CA3 region. Our results suggest that cordycepin exerts a nootropic role possibly through modulating A2AR density of hippocampus, which further support the concept that it is mostly A2AR rather than A1R to control the adaptive processes of memory performance. These findings would be helpful to provide a new window into the pharmacological properties of cordycepin for cognitive promotion. PMID- 29174914 TI - Src family kinases (SFKs) and cell polarity in the testis. AB - Non-receptor Src family kinases (SFKs), most notably c-Src and c-Yes, are recently shown to be expressed by Sertoli and/or germ cells in adult rat testes. Studies have shown that SFKs are involved in modulating the cell cytoskeletal function, and involved in endocytic vesicle-mediated protein endocytosis, transcytosis and/or recycling as well as intracellular protein degradation events. Furthermore, a knockdown to SFKs, in particular c-Yes, has shown to induce defects in spermatid polarity. These findings, coupled with emerging evidence in the field, thus prompt us to critically evaluate them to put forth a developing concept regarding the role of SFKs and cell polarity, which will become a basis to design experiments for future investigations. PMID- 29174916 TI - Guidance of retinal axons in mammals. AB - In order to navigate through the surrounding environment many mammals, including humans, primarily rely on vision. The eye, composed of the choroid, sclera, retinal pigmented epithelium, cornea, lens, iris and retina, is the structure that receives the light and converts it into electrical impulses. The retina contains six major types of neurons involving in receiving and modifying visual information and passing it onto higher visual processing centres in the brain. Visual information is relayed to the brain via the axons of retinal ganglion cells (RGCs), a projection known as the optic pathway. The proper formation of this pathway during development is essential for normal vision in the adult individual. Along this pathway there are several points where visual axons face 'choices' in their direction of growth. Understanding how these choices are made has advanced significantly our knowledge of axon guidance mechanisms. Thus, the development of the visual pathway has served as an extremely useful model to reveal general principles of axon pathfinding throughout the nervous system. However, due to its particularities, some cellular and molecular mechanisms are specific for the visual circuit. Here we review both general and specific mechanisms involved in the guidance of mammalian RGC axons when they are traveling from the retina to the brain to establish precise and stereotyped connections that will sustain vision. PMID- 29174917 TI - Non-identical twins: Different faces of CR3 and CR4 in myeloid and lymphoid cells of mice and men. AB - Integrins are cell membrane receptors that are involved in essential physiological and serious pathological processes. Their main role is to ensure a closely regulated link between the extracellular matrix and the intracellular cytoskeletal network enabling cells to react to environmental stimuli. Complement receptor type 3 (CR3, alphaMbeta2, CD11b/CD18) and type 4 (CR4, alphaXbeta2, CD11c/CD18) are members of the beta2-integrin family expressed on most white blood cells. Both receptors bind multiple ligands like iC3b, ICAM, fibrinogen or LPS. beta2-integrins are accepted to play important roles in cellular adhesion, migration, phagocytosis, ECM rearrangement and inflammation. Several pathological conditions are linked to the impaired functions of these receptors. CR3 and CR4 are generally thought to mediate overlapping functions in monocytes, macrophages and dendritic cells, therefore the potential distinctive role of these receptors has not been investigated so far in satisfactory details. Lately it has become clear that a functional segregation has evolved between the two receptors regarding phagocytosis, cellular adhesion and podosome formation. In addition to their tasks on myeloid cells, the expression and function of CR3 and CR4 on lymphocytes have also gained interest recently. The picture is further complicated by the fact that while these beta2-integrins are expressed by immune cells both in mice and humans, there are significant differences in their expression level, functions and the pathological consequences of genetic defects. Here we aim to summarize our current knowledge on CR3 and CR4 and highlight the functional differences between these receptors, involving their expression in myeloid and lymphoid cells of both men and mice. PMID- 29174915 TI - Midline axon guidance in the Drosophila embryonic central nervous system. AB - Studies in the fruit fly Drosophila melanogaster have provided many fundamental insights into the genetic regulation of neural development, including the identification and characterization of evolutionarily conserved axon guidance pathways and their roles in important guidance decisions. Due to its highly organized and fast-developing embryonic nervous system, relatively small number of neurons, and molecular and genetic tools for identifying, labeling, and manipulating individual neurons or small neuronal subsets, studies of axon guidance in the Drosophila embryonic CNS have allowed researchers to dissect these genetic mechanisms with a high degree of precision. In this review, we discuss the major axon guidance pathways that regulate midline crossing of axons and the formation and guidance of longitudinal axon tracts, two processes that contribute to the development of the precise three-dimensional structure of the insect nerve cord. We focus particularly on recent insights into the roles and regulation of canonical midline axon guidance pathways, and on additional factors and pathways that have recently been shown to contribute to axon guidance decisions at and near the midline.

AB - Although, gastric cancer is one of the most common cancers worldwide, alpha fetoprotein (AFP) producing human epidermal growth factor receptor 2 (HER2) positive gastric cancers are rare. AFP producing gastric cancer has a poor prognosis and an appropriate treatment option has not been established to date. A 75-year-old woman with AFP- producing gastric cancer was treated with S-1, an oral fluoropyrimidine derivative, chemotherapy after distal gastrectomy. Recurrence of gastric cancer was observed after 18 months and immunohistochemistry analysis showed AFP and HER2 positive gastric cancer. The patient received combination therapy containing capecitabine, cisplatin, and trastuzumab. Computed tomography scans showed regression of the lymph node metastasis. The patient's quality of life substantially improved after the treatment. Thus, the present case suggests that AFP and HER2 positive gastric cancer can be effectively treated with, capecitabine, cisplatin, and trastuzumab combination therapy. PMID- 29174921 TI - Embryonic development of GABAergic terminals in the mouse hypothalamic nuclei involved in feeding behavior. AB - The inhibitory neurotransmitter gamma-amino butyric acid (GABA) plays important roles in energy balance and feeding behavior in the hypothalamus. To reveal the time course of GABAergic network formation, we examined the immunohistochemical localization of glutamic acid decarboxylase (GAD), a GABAergic neuron marker, vesicular GABA transporter (VGAT), a marker of inhibitory terminals, and K+-Cl- cotransporter2 (KCC2), which shifts GABA action from excitation to inhibition, in the developing mouse hypothalamus. GABAergic terminals, seen as GAD- and VGAT positive dots, increased in density during embryonic development. Moreover, the onset of KCC2 localization was almost concomitant with GABAergic terminal formation, and KCC2-positive profiles increased in density during development. This suggested that after the formation of GABAergic terminals, GABAergic action may change to inhibition in the hypothalamus. This maturation appears to proceed as follows: the lateral hypothalamus (LH) matures first, followed by the paraventricular nucleus (PVN) by the time of birth, while the ventromedial hypothalamus (VMH) and the arcuate nucleus (Arc) are not fully mature at the time of birth. Our findings suggest that GABAergic networks in the "feeding center" (LH) and the "exit" (PVN) may mature before birth, while those in the "satiety center" (VMH) and "higher control center" (Arc) may mature after birth. PMID- 29174922 TI - Detecting spinal pyramidal tract of amyotrophic lateral sclerosis patients with diffusion tensor tractography. AB - The objective of this study was to determine alteration of corticospinal tract in patients with amyotrophic lateral sclerosis (ALS) using diffusion tensor tractograhy (DTT) focusing on the cervical spinal cord (C5) and transcranial magnetic stimulation (TMS). We recruited 38 ALS, 6 spinal and bulbar muscular atrophy (SBMA), 7 spastic paraplegia (SP) patients, and 8 age-matched normal controls, and then ALS were divided into two subgroups according to their clinical type: 28 ALS-limb and 10 ALS-bulbar. DTT was performed using the diffusion tensor image (DTI) track module to reconstruct two fiber tracts via C5. The fractional anisotropy (FA) values of ALS-total and ALS-limb patients were significantly reduced compared with normal controls, and SBMA patients. On the other hand, the mean diffusivity (MD) values were not significantly different among normal controls and the three disease groups. The rate of disease progression (DeltaFRS-R) of ALS patients was significantly correlated with FA values and central motor conduction time (CMCT). In conclusion, the present study demonstrated a significant reduction of FA values in ALS patients, and the DeltaFRS-R of ALS patients showed distinct regressions with FA values and CMCT, suggesting that this DTT analysis could be useful for detecting disease progression of ALS patients. PMID- 29174923 TI - Inorganic nitrite and nitrate in cardiovascular therapy: A better alternative to organic nitrates as nitric oxide donors? AB - In 1867 the organic nitrite, amyl nitrite, was introduced as a therapeutic agent in the treatment of angina pectoris and was later substituted by the organic nitrate nitroglycerin (NTG). Despite having a highly potent vasodilator capacity in veins>coronary arteries>arterioles, the vasodilator effects NTG are rapidly attenuated by the development of nitrate tolerance. We and others established that NTG treatment stimulates the production of reactive oxygen species such as superoxide and peroxynitrite with subsequent marked attenuation of the NTG vasodilator potency. The nitrite anion (NO2-) has more recently been characterized to possess novel pharmacotherapeutic actions such as modulation of vasodilation under hypoxic conditions, thereby providing protection in ischemia reperfusion injury. Administration of NO2-/NO3- has also been shown to improve myocardial function in heart failure and to lower blood pressure. Despite these positive aspects there is still a great need to study inorganic nitrate and nitrite therapy in various cardiovascular diseases in prospective outcome directed studies. In case being successful, this kind of therapy would indeed represent a cheap, therefore affordable, effective cardiovascular therapy without major side effects as observed in response to therapy with organic nitrates. PMID- 29174925 TI - The administration of surfactant decreased oxidative stress in lungs of mice exposed to cigarette smoke. AB - The alveolar surfactant, which composition consists of a unique and complex mixture of lipids and proteins, has immunomodulatory action. This study aimed to evaluate the effects of exogenous surfactant on pulmonary inflammatory response in mice exposed to cigarette smoke (CS). Twenty-four mice C57BL/6 were divided into four groups: control group exposed to ambient air (CG); surfactant treated group (SG); CS exposed group (CSG) and CS exposed group treated with surfactant (CSSG). For five days, CSG and CSSG were exposed to 12 commercial cigarettes/day and SG and CSSG received the surfactant by intranasal instillation. At the end of the experiment, the animals were euthanatized for the collection of bronchoalveolar lavage fluid (BALF) and lungs. The total number of leukocytes in BALF increased in CSG compared to CG, however, there was a decrease in CSSG compared to CSG. There was an increase in lipid peroxidation in SG and CSG compared to CG while there was a decrease in CSSG compared to CSG. Regarding the antioxidant enzymes, the catalase (CAT) activity increased in all groups compared to CG and the superoxide dismutase (SOD) activity decreased in CSG compared to the CG and SG. There was an increase in TNF in SG, CSG and CSSG compared to CG. There was an increase in IL-17 in CSSG compared to CG. There was an increase in CCL5 in SG and CSSG compared to CG. Therefore, our results demonstrated that the administration of exogenous surfactant was able to decrease the oxidative processes in the lungs of mice induced by short-term exposure to CS. PMID- 29174924 TI - The Output of Protein-Coding Genes Shifts to Circular RNAs When the Pre-mRNA Processing Machinery Is Limiting. AB - Many eukaryotic genes generate linear mRNAs and circular RNAs, but it is largely unknown how the ratio of linear to circular RNA is controlled or modulated. Using RNAi screening in Drosophila cells, we identify many core spliceosome and transcription termination factors that control the RNA outputs of reporter and endogenous genes. When spliceosome components were depleted or inhibited pharmacologically, the steady-state levels of circular RNAs increased while expression of their associated linear mRNAs concomitantly decreased. Upon inhibiting RNA polymerase II termination via depletion of the cleavage/polyadenylation machinery, circular RNA levels were similarly increased. This is because readthrough transcripts now extend into downstream genes and are subjected to backsplicing. In total, these results demonstrate that inhibition or slowing of canonical pre-mRNA processing events shifts the steady-state output of protein-coding genes toward circular RNAs. This is in part because nascent RNAs become directed into alternative pathways that lead to circular RNA production. PMID- 29174926 TI - Factors Associated With Response to Teduglutide in Patients With Short-Bowel Syndrome and Intestinal Failure. AB - BACKGROUND & AIMS: Clinical studies showed teduglutide to increase urine production and reduce need for parenteral support volume in patients with short bowel syndrome (SBS) with intestinal failure, increasing intestinal wet weight absorption and reducing diarrhea. However, the effects of teduglutide on parenteral support vary among patients. We performed a post hoc analysis of a phase III placebo-controlled study to identify characteristics of patients in whom teduglutide has the largest effects on parenteral support volume response. METHODS: We collected data from 85 patients with SBS with intestinal failure, according to the European Society for Clinical Nutrition and Metabolism classification system, who received teduglutide or placebo between November 25, 2008, and January 4, 2011, at 27 sites in 10 countries. Changes in parenteral support volume were evaluated according to baseline parenteral support volume, bowel anatomy (group 1, jejunostomy/ileostomy; group 2, >=50% colon-in-continuity without stoma; and group 3, other colon anatomies), and disease features (with inflammatory bowel disease, mesenteric vascular diseases, or other conditions). Correlation analyses were conducted using simple linear regression models, with unadjusted r2 values reported. Two-sided t tests were used for comparisons between treatment groups. RESULTS: We correlated parenteral support volume reduction with teduglutide treatment and baseline parenteral support volume (y = 0.3870x + 90.0279, r2 = 0.61; P < .0001). The effects of teduglutide on absolute parenteral support volume were significantly greater in group 1 patients (reduction of 919 +/- 644 mL/d), not only compared with patients given placebo (reduction of 340 +/- 436 mL/d; P = .0112) but also compared with teduglutide treated patients in group 2 (reduction of 355 +/- 306 mL/d; P = .0066). Teduglutide had an intermediate effect on patients in group 3. A minority of patients with SBS and inflammatory bowel diseases had colon-in-continuity (10.5% [n = 2/19]), whereas most patients with SBS and vascular or other diseases had colon-in-continuity (84.4% [n = 27/32] and 67.6% [n = 23/34], respectively). CONCLUSIONS: In a post hoc analysis of data from a phase III study of the effects of teduglutide on patients with SBS, we associated reduced parenteral support volume with baseline parenteral support volume, bowel anatomy, and SBS features. These findings may inform initial parenteral support volume adjustments and management of these severely disabled patients.

AB - BACKGROUND & AIMS: Recommendations for surveillance after curative surgery for colorectal cancer (CRC) include a 1-year post-resection abdominal-pelvic computed tomography (CT) scan and optical colonoscopy (OC). CT colonography (CTC), when used in CRC screening, effectively identifies colorectal polyps >=10 mm and cancers. We performed a prospective study to determine whether CTC, concurrent with CT, could substitute for OC in CRC surveillance. METHODS: Our study enrolled 231 patients with resected stage 0-III CRC, identified at 5 tertiary care academic centers. Approximately 1 year after surgery, participants underwent outpatient CTC plus CT, followed by same-day OC. CTC results were revealed after endoscopic visualization of sequential colonic segments, which were re-examined for discordant findings. The primary outcome was performance of CTC in the detection of colorectal adenomas and cancers using endoscopy as the reference standard. RESULTS: Of the 231 participants, 116 (50.2%) had polyps of any size or histology identified by OC, and 15.6% had conventional adenomas and/or serrated polyps >=6 mm. No intra-luminal cancers were detected. CTC detected patients with polyps of >=6 mm with 44.0% sensitivity (95% CI, 30.2-57.8) and 93.4% specificity (95% CI, 89.7-97.0). CTC detected polyps >=10 mm with 76.9% sensitivity (95% CI, 54.0-99.8) and 89.0% specificity (95% CI, 84.8-93.1). Similar values were found when only adenomatous polyps were considered. The negative predictive value of CTC for adenomas >=6 mm was 90.7% (95% CI, 86.7-94.5) and for adenomas >=10 mm the negative predictive value was 98.6% (95% CI, 97.0-100). CONCLUSIONS: In a CRC surveillance population 1 year following resection, CTC was inferior to OC for detecting patients with polyps >=6 mm. Clinical Trials.gov Registration Number: NCT02143115.

PMID- 29174930 TI - The use of fine needle aspiration and trends in incidence of thyroid cancer in Taiwan. AB - BACKGROUND: Thyroid cancer is the most prevalent endocrine malignancy, and the incidence of thyroid cancer has increased worldwide. Fine needle aspiration (FNA) for cytology of thyroid tissue is used for differentiating thyroid cancers from benign thyroid nodules. Overuse of FNA may detect subclinical thyroid cancer and play a role in the increased incidence of thyroid cancer. The aim of this study was to evaluate trends in incidence of thyroid cancer and the use of palpation guided FNA thyroid and ultrasound-guided FNA thyroid in Taiwan. METHODS: By retrospectively analyzing a cohort dataset of one million people randomly sample to represent as NHI beneficiaries of Taiwan National Health Insurance Research Database from 2004 to 2010, patients who received palpation-guided and ultrasound guided thyroid FNA were identified. Individuals who were diagnosed as having thyroid cancer were determined. Age-standardized, yearly rates of palpation guided thyroid FNA and ultrasound-guided FNA, and age-standardized, yearly incidence rates of thyroid cancer were calculated. RESULTS: In the study period, a total of 541 patients were newly diagnosed with thyroid cancer, 14,240 individuals received palpation-guided thyroid FNA, and 3823 individuals underwent ultrasound-guided thyroid FNA. There was a 94.8% increase in the age-standardized annual incidence rate of thyroid cancer. The age-standardized rates of palpation guided thyroid FNA and ultrasound-guided thyroid FNA increased by 10.9% and 349.3%, respectively. CONCLUSION: FNA for cytology of thyroid tissue, especially ultrasound-guided FNA, was conducted by physicians more frequently in Taiwan. Increased use of FNA, especially ultrasound-guided FNA for cytology of thyroid tissue, may attribute to the increased incidence of thyroid cancer in Taiwan. PMID- 29174931 TI - Group 1. Epidemiology of primary and secondary adrenal insufficiency: Prevalence and incidence, acute adrenal insufficiency, long-term morbidity and mortality. AB - The prevalence of primary adrenal insufficiency is estimated at between 82 144/million, with auto-immunity being the most common cause in adults and genetic causes, especially enzyme defects, being the most common cause in children. The prevalence of secondary adrenal deficiency is estimated to be between 150 280/million. The most frequent occurrence is believed to be corticosteroid induced insufficiency, despite the incidence of clinically relevant deficiency after cessation of glucocorticoid treatment being widely debated. Data on mortality in adrenal insufficiency are contradictory, with studies from Sweden suggesting a two-fold increase in comparison to the general population, but this is not consistently reported in all studies. However, increased mortality has been consistently reported in young patients, associated with infection and/or acute adrenal insufficiency. Acute adrenal deficiency (adrenal crisis) occurs in primary as well as secondary adrenal insufficiency. Its incidence, mostly determined in retrospective studies, is estimated in Europe at 6-8/100 patients/year. A prospective study reported 0.5 deaths/100 patient-years from adrenal crisis. Long-term morbidity of adrenal insufficiency is not well established, the increased cardiovascular risk or bone demineralization which are not consistently reported may also be due to a supraphysiological glucocorticoid replacement therapy. However, alteration in quality of life, both in physical and mental health components, has been demonstrated by several studies in both primary and secondary adrenal insufficiency. PMID- 29174928 TI - Efficacy of Indigo Naturalis in a Multicenter Randomized Controlled Trial of Patients With Ulcerative Colitis. AB - BACKGROUND & AIMS: Indigo naturalis (IN) is a traditional Chinese medicine that contains ligands for the aryl hydrocarbon receptor and promotes regeneration of the mucosa by inducing production of interleukin 22. IN might induce mucosal healing in patients with ulcerative colitis (UC). We performed a randomized controlled trial to investigate the safety and efficacy of IN in patients with UC. METHODS: We performed a multicenter, double-blind trial evaluating the safety of 86 patients in Japan with active UC (Mayo scores of 6 or more), enrolled from March 30 through December 27, 2016. Patients were randomly assigned to groups and given a daily dose of 0.5, 1.0, or 2.0 g IN or placebo (1:1:1:1 ratio) for 8 weeks. The primary endpoint was the rate of clinical response at week 8, defined as a 3-point decrease in the Mayo score and a decrease of at least 30% from baseline, with a decrease of at least 1 point for the rectal bleeding subscore or absolute rectal bleeding score of 0-1. The main secondary endpoint was the rate of clinical remission at week 8, defined as a Mayo score or <=2 and no subscores with a value >1. Mucosal healing was also assessed at week 8. RESULTS: The trial was terminated because of an external reason: a report of pulmonary arterial hypertension in a patient who used self-purchased IN for 6 months. In the intent to-treat analysis, we observed a significant, dose-dependent linear trend in proportions of patients with clinical responses (13.6% with a clinical response to placebo; 69.6% to 0.5 g IN; 75.0% to 1.0 g IN; and 81.0% to 2.0 g IN) (Cochran Armitage trend test P < .0001 compared with placebo). Proportions of patients in clinical remission at week 8 were significantly higher in the 1.0 g IN group (55.0%, P = .0004) and the 2.0 g IN group (38.1%, (P = .0093) than in the placebo group (4.5%). Proportions of patients with mucosal healing were 13.6% in the placebo group, 56.5% in the 0.5 g IN group, 60.0% in the 1.0 g IN group, and 47.6% in the 2.0 g IN group (P = .0278 compared with placebo). Although mild liver dysfunction was observed in 10 patients who received IN, no serious adverse events were observed. CONCLUSIONS: In a randomized, placebo-controlled trial, we found 8 weeks of IN (0.5-2.0 g per day) to be effective in inducing a clinical response in patients with UC. However, IN should not yet be used because of the potential for adverse effects, including pulmonary arterial hypertension. Clinical Trials Registry no: UMIN000021439 (http://www.umin.ac.jp/ctr/).

PMID- 29174933 TI - Surviving at a distant site: The organotropism of metastatic breast cancer. AB - Many cancers demonstrate a non-random distribution of sites for distant relapse while others have the propensity to metastasize to multiple organ systems. One of the notable recent findings is that the breast cancer subtypes differ not only in their biological characteristics as primary tumors but also in their capacity for metastatic progression. This information could potentially be utilized in treatment decision making and surveillance strategies.

AB - Several primary pathologic entities in diverse anatomic locations have the potential to simulate metastatic neoplasms histologically. Their misinterpretation as such may result in needless and extensive clinical evaluations that are intended to detect a presumed malignancy at another site. More importantly, mistakes of this type can deprive patients of surgical excisions that could be curative. This presentation considers a review of selected primary lesions that can simulate metastases. They include hemangioblastoma, glioblastoma and meningioma with epithelial metaplasia, choroid plexus carcinomas, primary neuroendocrine carcinomas in unusual locations, special forms of sinonasal and salivary glandular adenocarcinoma, clear-cell thyroid carcinomas, unusual microscopic subtypes of pulmonary adenocarcinoma, epithelioid myomelanocytomas ("sugar tumors"), mesotheliomas, primary thymic carcinomas, endodermal choristomas of the interatrial myocardium, peripheral cholangiocarcinoma, adrenocortical carcinoma, adenocarcinomas of the urinary bladder, mucinous and "rhabdoid" tumors of the ovaries, rete testis adenocarcinomas, interdigitating dendritic-cell sarcoma of lymph nodes, selected sweat gland carcinomas, cutaneous Merkel cell carcinoma, primary dermal and subcutaneous melanoma, mucosal and visceral melanomas, epithelioid sarcoma, clear cell sarcoma, and adamantinoma of long bones.

AB - PURPOSE: To report survival outcomes in women with Stage II uterine endometrioid carcinoma who received adjuvant radiation therapy (RT) without chemotherapy using the National Cancer Database. METHODS AND MATERIALS: The National Cancer Database was queried for women with International Federation of Gynecology and Obstetrics Stage II uterine endometrioid carcinoma who underwent hysterectomy followed by adjuvant RT without chemotherapy. The chi2 tests were performed to compare differences in outcome by type of adjuvant RT (external beam radiation therapy [EBRT] alone, vaginal brachytherapy [VBT] alone, or combination of EBRT and VBT). Overall survival (OS) was assessed by Kaplan-Meier and log-rank tests. Univariate and multivariate analyses were performed to identify predictors of OS. RESULTS: We identified 2681 women. Simple hysterectomy was performed on 2261 women (84%). Adjuvant EBRT, VBT, and combination RT were administered to 27%, 36%, and 37%, respectively. There was a statistically significant difference in OS by modality of adjuvant RT (p = 0.01) favoring women who received VBT alone or in combination with EBRT. The 5-year OS was 80%, 87%, and 83% for women who received EBRT, VBT, and combination RT, respectively (p = 0.001). On multivariate analysis, old age, African-American race, no or fewer number of examined lymph nodes, and higher tumor grade were independent predictors of worse OS. RT modality did not sustain its independent prognostic significance as a predictor of OS. CONCLUSIONS: In this nationwide hospital-based study of women with International Federation of Gynecology and Obstetrics Stage II uterine endometrioid carcinoma, adjuvant VBT alone provided excellent survival outcomes and may be a reasonable adjuvant RT modality for properly selected women with adequate lymph node dissection and low grade tumors. PMID- 29174936 TI - Quantitative CT assessment of a novel direction-modulated brachytherapy tandem applicator. AB - PURPOSE: The purpose of this study was to quantitatively assess the CT metal induced artifacts from a novel direction-modulated brachytherapy (DMBT) tandem applicator prototype, recently designed for cervical cancer treatments. METHODS AND MATERIALS: A water-based pelvic phantom was constructed for CT scanning. The DMBT applicator was imaged using our institutional protocol, one with higher kVp and mAs settings, and repetition of these protocols using 3-mm slices. A conventional stainless steel applicator was also scanned. In addition to the standard reconstructed images, applicator images were reconstructed using a commercial metal artifact-reduction (MAR) algorithm and an in-house-developed research algorithm. Subsequently, image quality and artifact severity were evaluated. RESULTS: Artifact severity, measured in terms of SDs in CT numbers, decreased asymptotically to background water levels with the distance away from the applicator. Artifact-reduction algorithms lead to significant and visible improvements in image quality, with >50% and >20% decrease in artifact severity achieved at a 10-mm distance for the DMBT and stainless steel applicators, respectively. Differences in artifact severity were minimal between the four imaging protocols. DMBT dimensions were the same on images with and without the commercial MAR algorithm, within <1 mm of the theoretical value. Both the commercial and in-house algorithms restored the CT numbers outside the applicator, albeit a better performance was achieved by the in-house algorithm. CONCLUSIONS: The artifacts produced by both applicators were minimized with the use of MAR algorithms. Adoption of the DMBT and stainless steel applicators for CT-guided brachytherapy is anticipated as MAR algorithms are widely available on CT scanners.

AB - PURPOSE: The purpose of the study was to evaluate the results of high-dose-rate plesiobrachytherapy for local relapse after mastectomy and radiotherapy in terms of both local control and survival. METHODS: We reviewed retrospectively 43 patients who experienced a chest wall relapse of breast cancer after local excision (22 patients) or not (21 patients). Patients were treated with an individually designed mold with four to six fractions of 3-6 Gy high-dose-rate brachytherapy, two fractions per week. Mean total dose was 24 Gy. RESULTS: After surgical resection, the 3- and 5-year local control rates were 80% and 73%, respectively. For nonresectable patients, the overall response rate was 86%, and the 3-year infield local control and chest wall local control were 51% and 26%, respectively. The 5-year survival rate was 50.5% for the whole population, 62% after surgery, and 45.4% for irresectable patients. Acute Grade 2 or 3 toxicity occurred in 43% of the patients, resolving in a few days. Two patients had a local necrosis lasting 3 to 7 months. Late toxicity was observed in 5 patients. CONCLUSIONS: High-dose-rate plesiobrachytherapy is a simple outpatient technique to treat chest wall local relapse of breast cancer. As a reirradiation technique, its tolerance is acceptable. This technique may obtain long-term local control after incomplete surgery; in case of nonresectable disease, a high response rate was observed, which might improve the quality of life of these patients. PMID- 29174937 TI - Reductions in prostatic doses are associated with less acute morbidity in patients undergoing Pd-103 brachytherapy: Substantiation of the rationale for focal therapy. AB - PURPOSE: Interest in prostate dose reduction or focal treatment exists due to expected reductions in treatment morbidity. Prior analyses have not generally corroborated relationships between prostate or urethral dose and urinary toxicity after brachytherapy, but such analyses have been performed on cohorts all receiving the same prescribed dose. We analyzed patients treated to differing prescription doses to assess acute urinary morbidity with dose reduction. METHODS AND MATERIALS: Patients treated with Pd-103 to either 125 Gy or 90-100 Gy were compared using the International Prostate Symptom Score (IPSS) at 1-month postimplant. Patients in the 90-100 Gy cohort began external beam radiation therapy after their 1-month assessment; thus, toxicities were measured before contribution from external beam radiation therapy. Patient/treatment characteristics were compared to verify subgroup homogeneity. Dose and change in IPSS 1 month after treatment were assessed using a multivariate linear regression model. RESULTS: One hundred ninety-one and 41 patients were treated with 125 Gy versus 90-100 Gy, respectively. Preimplant and postimplant prostate volumes and initial IPSS were similar between groups. Higher prescription dose and increased pretreatment IPSS were independent predictors of increased 1-month IPSS. In addition, every 10 percentage point additional prostate volume receiving a given dose was associated with increase in IPSS after treatment for the same level of pretreatment IPSS. CONCLUSION: Lower prescription dose and decreased volume of high-dose regions to the prostate correlated with reduced acute urinary morbidity after brachytherapy. Our findings suggest that focal treatment approaches with modest dose reductions to subregions of the prostate may reduce acute morbidity and potentially expand the number of patients eligible for brachytherapy. PMID- 29174939 TI - Physician Intervention to Positive Depression Screens Among Adolescents in Primary Care. AB - PURPOSE: The objective of this study was to determine the effectiveness of computer-based screening and physician feedback to guide adolescent depression management within primary care. METHODS: We conducted a prospective cohort study within two clinics of the computer-based depression screening and physician feedback algorithm among youth aged 12-20 years between October 2014 and October 2015 in Marion County (Indianapolis), Indiana. RESULTS: Our sample included 2,038 youth (51% female; 60% black; mean age = 14.6 years [standard deviation = 2.1]). Over 20% of youth screened positive for depression on the Patient Health Questionnaire-2 and 303 youth (14.8%) screened positive on the Patient Health Questionnaire-9 (PHQ-9). The most common follow-up action by physicians was a referral to mental health services (34.2% mild, 46.8% moderate, and 72.2% severe range). Almost 11% of youth in the moderate range and 22.7% of youth in the severe range were already prescribed a selective serotonin reuptake inhibitor. When predicting mental health service referral, significant predictors in the multivariate analysis included clinic site (40.2% vs. 73.9%; p < .0001) and PHQ-9 score (severe range 77.8% vs. mild range 47.5%; p < .01). Similarly, when predicting initiation of selective serotonin reuptake inhibitors, only clinic site (28.6% vs. 6.9%; p < .01) and PHQ-9 score (severe range 46.7% vs. moderate range 10.6%; p < .001) were significant. CONCLUSIONS: When a computer-based decision support system algorithm focused on adolescent depression was implemented in two primary care clinics, a majority of physicians utilized screening results to guide clinical care. PMID- 29174940 TI - Absorbable Hydrogel Spacer Use in Prostate Radiotherapy: A Comprehensive Review of Phase 3 Clinical Trial Published Data. AB - OBJECTIVE: To provide an update on SpaceOAR System, a Food and Drug Administration-approved hydrogel indicated to create distance between the prostate and the rectum which has been studied in phase 2 and 3 clinical trials. Here, we review and summarize these clinical results including the safety of prostate-rectum spacer application technique, the implant quality and resulting rectal dose reduction, acute and long-term rectal, urinary, and sexual toxicity, as well as patient-reported outcomes. MATERIALS AND METHODS: A prospective, randomized patient-blinded clinical study was performed comparing image-guided intensity modulated prostate radiotherapy (79.2 Gy in 44 fractions) in men with or without prostate-rectum hydrogel spacer. Patients were followed up for 3 years, allowing assessment of long-term safety and efficacy. RESULTS: Spacer application was well tolerated with a 99% technical success rate. The mean additional space created between the prostate and the rectum was just over 1 cm, which allowed significant rectum and penile bulb radiation dose reduction, resulting in less acute pain, lower rates of late rectal toxicity, and improved bowel and urinary quality of life (QOL) scores from 6 months onward. Improvements in sexual QOL were also observed at 37 months in baseline-potent men, with 37.5% of control and 66.7% of spacer men capable of "erections sufficient for intercourse." CONCLUSION: Prostate-rectum hydrogel spacer application is a relatively safe technical procedure that is well tolerated and has a high technical success rate. Spacer application significantly reduces rectal radiation dose and results in long-term reductions in rectal toxicity, as well as improvements in bowel, urinary, and sexual QOL. PMID- 29174941 TI - Is Delayed Phase Computed Tomography Imaging Necessary After Blunt Renal Trauma in Children? AB - OBJECTIVE: To characterize the utilization of delayed phase computed tomography (CT) imaging in blunt renal trauma and determine if the omission of delayed phase CT imaging affected clinical outcomes in children. MATERIALS AND METHODS: A prospectively collected trauma database was reviewed between 2006 and 2016 to identify patients aged <=21 years with a diagnosis of renal injury from blunt trauma. Demographic characteristics, injury grade, Injury Severity Score, non kidney organ injuries, radiologic studies, and clinical course were reviewed. Patients were categorized into 2 groups: those who received CT with delayed images in the emergency room and those who did not. RESULTS: In total, 121 patients met the inclusion criteria. Delayed scans were obtained in 50 patients (41%) but omitted in 71 (59%). Age, weight, non-kidney organ injuries, and imaging location did not differ between groups. Injury Severity Score was higher in the no-delay group than in the delay group (median 16 vs 10, respectively, P = .40). Median length of stay was 3 days without significant differences by cohort (P = .24). The proportion of patients who received abdominal CT scans after admission, underwent a urologic procedure, or were readmitted did not differ significantly between groups. CONCLUSION: This study was unable to demonstrate a difference in outcomes between patients who had a CT with delayed imaging and patients who did not. This questions the universal necessity for delayed images after blunt renal trauma. Future prospective studies are necessary to develop pediatric trauma guidelines that balance imaging needs and radiation exposure. PMID- 29174942 TI - Comparative Effectiveness of Initial Surgery vs Initial Systemic Therapy for Metastatic Kidney Cancer in the Targeted Therapy Era: Analysis of a Population based Cohort. AB - OBJECTIVE: To use econometric methods to assess comparative overall survival of patients with metastatic renal cell carcinoma (mRCC) managed with initial cytoreductive nephrectomy (CN) vs initial systemic therapy. Randomized data demonstrate improved survival for CN preceding cytokine-based therapy in mRCC. This benefit may be attenuated in the contemporary mRCC era given more effective systemic therapies. METHODS: Patients over age 65 with mRCC from the Surveillance, Epidemiology, and End Results registries linked with Medicare claims from 2006 to 2011 were categorized by initial treatment. We applied sequential survival analysis methods to assess the association between initial CN and overall survival (OS) including Cox proportional hazards models, propensity scoring, and instrumental variable analysis to account for measured and unmeasured selection bias. RESULTS: Of 537 patients analyzed, 190 had initial CN followed by targeted therapy and 347 had initial targeted therapy. Median OS in the initial CN group was 17.4 months (interquartile range 9.8-32.0), compared with 9.2 months (interquartile range 4.3-18.0) for initial targeted therapy. Cox proportional hazards analysis revealed initial CN was associated with improved OS (hazard ratio 0.50, 95% confidence interval [CI] 0.38-0.65). Propensity matching demonstrated a survival advantage for initial CN of 5.8 months (95% CI 1.9-9.7). Accounting for unmeasured confounding with instrumental variable analysis demonstrated a trend toward improved survival with initial CN (hazard ratio 0.29 [95% CI 0.08-1.00]). CONCLUSION: Initial CN is associated with improved survival compared with initial systemic therapy in a contemporary population-based mRCC cohort. PMID- 29174943 TI - Use of 99mTc-sestamibi Single-photon Emission Computed Tomography / X-ray Computed Tomography in the Diagnosis of Hybrid Oncocytic / Chromophobe Tumor in a Pediatric Patient. AB - The differential diagnosis of solid renal neoplasms in adolescence includes aggressive malignancy and indolent oncocytic tumors, which are typically indistinguishable using conventional imaging. We report the use of 99mTc sestamibi single-photon emission computed tomography / x-ray computed tomography (SPECT/CT) in characterizing enhancing renal neoplasms in a pediatric patient. Genetic testing suggested a hereditary syndrome associated with aggressive malignancy, whereas renal mass biopsy suggested an oncocytic tumor. 99mTc sestamibi SPECT/CT indicated probable oncocytomas or hybrid oncocytic / chomophobe tumors. Enucleative resection was performed with final pathology demonstrating hybrid oncocytic / chomophobe tumors. This case highlights the potential utility of 99mTc-sestamibi SPECT/CT in characterizing indeterminate enhancing renal neoplasm in pediatric patients. PMID- 29174944 TI - Is there a benefit to adjuvant radiation in stage III penile cancer after lymph node dissection? Findings from the National Cancer Database. AB - OBJECTIVE: The role of adjuvant radiation in advanced penile cancer (PC) is unknown. We used the National Cancer Database (NCDB) to determine factors associated with receiving adjuvant radiation (aXRT) and their influence on prognosis in men who underwent inguinal lymph node dissection (ILND) for stage III disease. MATERIALS AND METHODS: We queried the NCDB from 1998-2012 for all men with PC who had pathologic nodal status and aXRT data available. Clinical and pathologic variables associated with aXRT were examined using chi-square testing. Logistic regression evaluated the odds of receiving aXRT while multivariate Cox regression analysis evaluated the influence of aXRT on overall survival (OS). RESULTS: A total of 589 patients underwent ILND for stage III PC with 23% (N = 136) receiving aXRT. Mean age was 61.8 +/-13.7 years. Factors associated with receiving aXRT included higher pathologic nodal stage (MV OR 1.85, 95% CI: 1.13 3.05), while greater distance of travel (MV OR 0.48, 95% CI: 0.25-0.92), and treatment in an academic setting (MV OR 0.53, 95% CI: 0.35-0.81) were inversely associated with receiving aXRT. On Cox regression analysis, aXRT improved OS (combined HR 0.58, 95% CI: 0.39-0.86), which appeared to have been driven by higher nodal burden (N2: HR 0.53, 95% CI: 0.32-0.88; N1: HR 1.36, 95% CI: 0.60 3.09). CONCLUSIONS: Determinants of aXRT delivery in stage III PC appear to be related to the proximity to community cancer centers and greater nodal burden. We find evidence of a survival benefit with the use of aXRT, particularly in those with higher nodal stage. Multi-institutional studies are needed to confirm these findings and improve treatment algorithms for high-stage PC. PMID- 29174945 TI - Preoperative predictors of nonorgan-confined disease in upper-tract urothelial carcinoma differ between China and the United States. AB - OBJECTIVE: To compare preoperative predictors of nonorgan-confined (NOC) disease in patients with upper-tract urothelial carcinoma (UTUC) from the United States (US) and China. METHODS: Clinicopathologic data of patients with UTUC treated surgically at tertiary care facilities in the US or China from 1998 to 2015 were, retrospectively, compiled. Patient characteristics, preoperative imaging, cytology, ureteroscopic findings, and serum markers (neutrophil-to-lymphocyte ratio, estimated glomerular filtration rate, hemoglobin, and albumin) were evaluated. After excluding patients who received neoadjuvant chemotherapy, rates of NOC disease at definitive surgery were tabulated. Logistic regression and receiver operating characteristic analyses were performed to determine predictors of NOC for each country using previously published nomograms, and the cohorts were compared. RESULTS: Totally, 753 patients with UTUC were included for analysis (451 Chinese and 302 US). NOC rates were similar between the 2 countries (31% vs. 29%, P = 0.568). On multivariable analysis, cT3 stage (P = 0.001) and high-grade pathology on ureteroscopy (P = 0.011) were significant predictors for NOC in the US, while male gender (P = 0.034), tumor location on imaging (P = 0.009), tumor size on imaging (P = 0.044), neutrophil-to-lymphocyte (P = 0.043), and preoperative estimated glomerular filtration rate (P = 0.028) were significant in China. Areas under the curve differed by nomogram used (Western model: 0.750 in US, vs. 0.670 in China; Chinese model: 0.763 in US, vs. 0.828 in China). CONCLUSION: Predictors for NOC in UTUC differ between the US and China. There may be unique population-based markers that more profoundly influence the accuracy of nomograms in certain populations. Our findings highlight the importance of considering population differences when clinically applying predictive tools in UTUC. PMID- 29174946 TI - Fluoxetine, not donepezil, reverses anhedonia, cognitive dysfunctions and hippocampal proteome changes during repeated social defeat exposure. AB - While anhedonia is considered a core symptom of major depressive disorder (MDD), less attention has been paid to cognitive dysfunctions. We evaluated the behavioural and molecular effects of a selective serotonin re-uptake inhibitor (SSRI, fluoxetine) and an acetylcholinesterase inhibitor (AChEI, donepezil) on emotional-cognitive endophenotypes of depression and the hippocampal proteome. A chronic social defeat (SD) procedure was followed up by "reminder" sessions of direct and indirect SD. Anhedonia-related behaviour was assessed longitudinally by intracranial self-stimulation (ICSS). Cognitive dysfunction was analysed by an object recognition test (ORT) and extinction of fear memory. Tandem mass spectrometry (MSE) and protein-protein-interaction (PPI) network modelling were used to characterise the underlying biological processes of SD and SSRI/AChEI treatment. Independent selected reaction monitoring (SRM) was conducted for molecular validation. Repeated SD resulted in a stable increase of anhedonia-like behaviour as measured by ICSS. Fluoxetine treatment reversed this phenotype, whereas donepezil showed no effect. Fluoxetine improved recognition memory and inhibitory learning in a stressor-related context, whereas donepezil only improved fear extinction. MSE and PPI network analysis highlighted functional SD stress-related hippocampal proteome changes including reduced glutamatergic neurotransmission and learning processes, which were reversed by fluoxetine, but not by donepezil. SRM validation of molecular key players involved in these pathways confirmed the hypothesis that fluoxetine acts via increased AMPA receptor signalling and Ca2+-mediated neuroplasticity in the amelioration of stress-impaired reward processing and memory consolidation. Our study highlights molecular mediators of SD stress reversed by SSRI treatment, identifying potential viable future targets to improve cognitive dysfunctions in MDD patients. PMID- 29174947 TI - RBFOX1, encoding a splicing regulator, is a candidate gene for aggressive behavior. AB - The RBFOX1 gene (or A2BP1) encodes a splicing factor important for neuronal development that has been related to autism spectrum disorder and other neurodevelopmental phenotypes. Evidence from complementary sources suggests that this gene contributes to aggressive behavior. Suggestive associations with RBFOX1 have been identified in genome-wide association studies (GWAS) of anger, conduct disorder, and aggressive behavior. Nominal association signals in RBFOX1 were also found in an epigenome-wide association study (EWAS) of aggressive behavior. Also, variants in this gene affect temporal lobe volume, a brain area that is altered in several aggression-related phenotypes. In animals, this gene has been shown to modulate aggressive behavior in Drosophila. RBFOX1 has also been associated with canine aggression and is upregulated in mice that show increased aggression after frustration of an expected reward. Associated common genetic variants as well as rare duplications and deletions affecting RBFOX1 have been identified in several psychiatric and neurodevelopmental disorders that are often comorbid with aggressive behaviors. In this paper, we comprehensively review the cumulative evidence linking RBFOX1 to aggression behavior and provide new results implicating RBFOX1 in this phenotype. Most of these studies (genetic and epigenetic analyses in humans, neuroimaging genetics, gene expression and animal models) are hypothesis-free, which strengthens the validity of the findings, although all the evidence is nominal and should therefore be taken with caution. Further studies are required to clarify in detail the role of this gene in this complex phenotype. PMID- 29174948 TI - Divergent prefrontal dopaminergic mechanisms mediate drug- and fear-associated cue extinction during adolescence versus adulthood. AB - Cue-associated learning is vital to guiding behaviour for survival. Adolescence represents a key developmental stage for perturbations in cue-related learning, including a characteristic deficit in cue extinction learning. The present review summarizes evidence from animal and human literature that cue extinction is critically mediated by prefrontal dopamine, a system that undergoes dramatic reorganization during adolescence. We propose that extinction learning and memory is governed by a developmentally dynamic balance of dopamine receptors in the prefrontal cortex, which changes across adolescence into adulthood. This is contrary to the previous idea that extinction deficits during adolescence reflect inefficiency in the same neural circuitry as adults. This leads to proposal of the novel theory that cue extinction involves divergent prefrontal dopaminergic mechanisms depending on the age of extinction. PMID- 29174949 TI - Impaired repair of DNA damage is associated with autistic-like traits in rats prenatally exposed to valproic acid. AB - Prenatal exposure to the antiepileptic and mood stabilizer valproic acid (VPA) is an environmental risk factor for autism spectrum disorders (ASD), although recent epidemiological studies show that the public awareness of this association is still limited. Based on the clinical findings, prenatal VPA exposure in rodents is a widely used preclinical model of ASD. However, there is limited information about the precise biochemical mechanisms underlying the link between ASD and VPA. Here, we tested the effects of increasing doses of VPA on behavioral features resembling core and secondary symptoms of ASD in rats. Only when administered prenatally at the dose of 500mg/kg, VPA induced deficits in communication and social discrimination in rat pups, and altered social behavior and emotionality in the adolescent and adult offspring in the absence of gross malformations. This dose of VPA inhibited histone deacetylase in rat embryos and favored the formation of DNA double strand breaks (DSB), but impaired their repair. The defective DSB response was no more visible in one-day-old pups, thus supporting the hypothesis that unrepaired VPA-induced DNA damage at the time of neural tube closure may underlie the autistic-like traits displayed in the course of development by rats prenatally exposed to VPA. These experiments help to understand the neurodevelopmental trajectories affected by prenatal VPA exposure and identify a biochemical link between VPA exposure during gestation and ASD. PMID- 29174950 TI - A formative evaluation of a coach-based technical assistance model for youth- and family-focused programming. AB - BACKGROUND: The Children, Youth, and Families At-Risk (CYFAR) initiative provides funding and technical support for local community-based programs designed to promote positive outcomes among vulnerable populations. In 2013, CYFAR implemented significant changes in the way it provides technical assistance (TA) to grantees. These changes included introducing a new TA model in which trained coaches provide proactive support that is tailored to individual CYFAR projects. The purpose of this paper is to describe the evolution of this TA model and present preliminary findings from a formative evaluation. METHODS: CYFAR Principal Investigators (PIs) were invited to respond to online surveys in 2015 and 2016. The surveys were designed to assess PI attitudes towards the nature and quality of support that they receive from their coaches. RESULTS: CYFAR PIs reported that their coaches have incorporated a range of coaching skills and techniques into their work. PIs have generally positive attitudes towards their coaches, and these attitudes have become more positive over time. CONCLUSIONS: Results suggest that CYFAR PIs have been generally supportive of the new TA system. Factors that may have facilitated support include a strong emphasis on team-building and the provision of specific resources that support program design, implementation, and evaluation. PMID- 29174951 TI - Vocational training and employability: Evaluation evidence from Romania. AB - This study evaluates the direct effects of vocational training, which is a popular active labour market policy in a European developing country such as Romania. Since the available official statistical microdata were insufficient to conduct reliable impact evaluations, the main findings were obtained through a counterfactual impact evaluation using newly produced micro survey data. Moreover, the research provides a heterogeneity analysis of groups of trainees, in order to identify the categories for which the programme performs best. The main results reveal that the training measure has a positive, but modest impact upon employability in Romania: participation increases employment chances properly controlled by 15%. It is most successful for women and for people living in urban areas. Measures for increasing the impacts of the vocational training programme in Romania are identified in terms of better targeting and profiling the trainees and closer adjustment of the programme to the specific needs of the labour market.

PMID- 29174952 TI - Interactions Between Diet and the Intestinal Microbiota Alter Intestinal Permeability and Colitis Severity in Mice. AB - BACKGROUND & AIMS: It is not clear how the complex interactions between diet and the intestinal microbiota affect development of mucosal inflammation or inflammatory bowel disease. We investigated interactions between dietary ingredients, nutrients, and the microbiota in specific pathogen-free (SPF) and germ-free (GF) mice given more than 40 unique diets; we quantified individual and synergistic effects of dietary macronutrients and the microbiota on intestinal health and development of colitis. METHODS: C56BL/6J SPF and GF mice were placed on custom diets containing different concentrations and sources of protein, fat, digestible carbohydrates, and indigestible carbohydrates (fiber). After 1 week, SPF and GF mice were given dextran sulfate sodium (DSS) to induce colitis. Disease severity was determined based on the percent weight change from baseline, and modeled as a function of the concentration of each macronutrient in the diet. In unchallenged mice, we measured intestinal permeability by feeding mice labeled dextran and measuring levels in blood. Feces were collected and microbiota were analyzed by 16S rDNA sequencing. We collected colons from mice and performed transcriptome analyses. RESULTS: Fecal microbiota varied with diet; the concentration of protein and fiber had the strongest effect on colitis development. Among 9 fiber sources tested, psyllium, pectin, and cellulose fiber reduced the severity of colitis in SPF mice, whereas methylcellulose increased severity. Increasing dietary protein increased the density of the fecal microbiota and the severity of colitis in SPF mice, but not in GF mice or mice given antibiotics. Psyllium fiber reduced the severity of colitis through microbiota-dependent and microbiota-independent mechanisms. Combinatorial perturbations to dietary casein protein and psyllium fiber in parallel accounted for most variation in gut microbial density and intestinal permeability in unchallenged mice, as well as the severity of DSS-induced colitis; changes in 1 ingredient could be offset by changes in another. CONCLUSIONS: In an analysis of the effects of different dietary components and the gut microbiota on mice with and without DSS-induced colitis, we found complex mixtures of nutrients affect intestinal permeability, gut microbial density, and development of intestinal inflammation. PMID- 29174954 TI - Cell milieu significantly affects the fate of AApoAI amyloidogenic variants: predestination or serendipity? AB - BACKGROUND: Specific apolipoprotein A-I variants are associated to severe hereditary amyloidoses. The organ distribution of AApoAI amyloidosis seems to depend on the position of the mutation, since mutations in residues from 1 to 75 are mainly associated to hepatic and renal amyloidosis, while mutations in residues from 173 to 178 are mostly responsible for cardiac, laryngeal, and cutaneous amyloidosis. Molecular bases of this tissue specificity are still poorly understood, but it is increasingly emerging that protein destabilization induced by amyloidogenic mutations is neither necessary nor sufficient for amyloidosis development. METHODS: By using a multidisciplinary approach, including circular dichroism, dynamic light scattering, spectrofluorometric and atomic force microscopy analyses, the effect of target cells on the conformation and fibrillogenic pathway of the two AApoAI amyloidogenic variants AApoAIL75P and AApoAIL174S has been monitored. RESULTS: Our data show that specific cell milieus selectively affect conformation, aggregation propensity and fibrillogenesis of the two AApoAI amyloidogenic variants. CONCLUSIONS: An intriguing picture emerged indicating that defined cell contexts selectively induce fibrillogenesis of specific AApoAI variants. GENERAL SIGNIFICANCE: An innovative methodological approach, based on the use of whole intact cells to monitor the effects of cell context on AApoAI variants fibrillogenic pathway, has been set up. PMID- 29174955 TI - Cleft lip and palate subjects prevalence of abnormal stylohyoid complex and tonsilloliths on cone beam computed tomography. AB - INTRODUCTION AND OBJECTIVES: Tonsilloliths and abnormal stylohyoid complex may have similar symptoms to others of different aetiology. Individuals with cleft lip and palate describe similar symptoms because of the anatomical implications that are peculiar to this anomaly. The aim of this study was to determine the prevalence of abnormal stylohyoid complex and tonsilloliths on cone beam computed tomography in individuals with cleft lip and palate. METHODS: According to the inclusion and exclusion criteria, 66 CT scans out of of 2,794 were analysed, on i Cat (r) vision software with 0.8 index Kappa intra-examiner. RESULTS: The total prevalence of ossification of the incomplete stylohyoid complex in individuals with cleft lip and palate was 66.6%; the prevalence of these findings in females was 75% and 61.9% in males. The total prevalence of tonsilloliths was 7.5%. CONCLUSION: It is important to ascertain calcification of the stylohyoid complex and tonsilloliths in the radiological report, due to the anatomical proximity and similarsymptomatology to other orofacial impairments inindividuals with cleft lip and palate, focusing on females with oral cleft formation, patients with incisive trans foramen cleft and incisive post foramen cleft because they are more prevalent. Greater knowledge of the anatomical morphometry of individuals with cleft lip and palate greatly contributes towards the selection of clinical behaviours and the quality of life of these patients, since cleft lip and palateis one of the most common anomalies.

AB - INTRODUCTION: Although testosterone therapy (TTh) is an effective treatment for hypogonadism, recent concerns regarding its safety have been raised. In 2015, the US Food and Drug Administration issued a warning about potential cardiovascular risks resulting from TTh. Fertility preservation is another reason to search for viable alternative therapies to conventional TTh, and in this review we evaluate the literature examining these alternatives. AIMS: To review the role and limitations of non-testosterone treatments for hypogonadism. METHODS: A literature search was conducted using PubMed to identify relevant studies examining medical and non-medical alternatives to TTh. Search terms included hypogonadism, testosterone replacement therapy, testosterone therapy, testosterone replacement alternatives, diet and exercise and testosterone, varicocele repair and testosterone, stress reduction and testosterone, and sleep apnea and testosterone. MAIN OUTCOME MEASURES: Review of peer-reviewed literature. RESULTS: Medical therapies examined include human chorionic gonadotropins, aromatase inhibitors, and selective estrogen receptor modulators. Non-drug therapies that are reviewed include lifestyle modifications including diet and exercise, improvements in sleep, decreasing stress, and varicocele repair. The high prevalence of obesity and metabolic syndrome in the United States suggests that disease modification could represent a viable treatment approach for affected men with hypogonadism. CONCLUSIONS: These alternatives to TTh can increase testosterone levels and should be considered before TTh. Lo EM, Rodriguez KM, Pastuszak AW, Khera M.

AB - BACKGROUND: The intensive use of antibacterial and antifungal drugs has dramatically increased the microbial resistance and has led to a higher number of difficult-to-eradicate infections. Combination therapy with two or more antimicrobial drugs has emerged some years ago to overcome the issue, but it has proven to be not completely effective. Natural secondary metabolites of MW <= 500 represent promising adjuvants for antimicrobials and have been the object of several researches that have increased in the last two decades. PURPOSE: The purpose of this Review is to do a literature search of the natural compounds that showed high enhancing capacity of antibacterials' and antifungals' effects against planktonic bacteria and fungi and to analyze which are the natural products most used in combination with a focus on polyphenols and terpenoids. RESULTS: One hundred of papers were collected for reviewing. Fifty six (56) of them deal with combinations of low MW natural products with antibacterial drugs against planktonic bacteria and forty four (44) on natural products with antifungal drugs against planktonic fungi. Of the antibacterial adjuvants, 41 (73%) were either polyphenols (27; 48%) or terpenes (14; 25%). The remaining 15 papers (27%), deal with different class of natural products. Since most natural potentiators belong to the terpene or phenolic structural types, a more detailed description of the works dealing with these type of compounds is provided here. Bacterial and fungal resistance mechanisms, the modes of action of the main classes of antibacterial and antifungal drugs and the methodologies most used to assess the type of interactions in the combinations were included in the Review too. CONCLUSIONS AND PERSPECTIVES: Several promising results on the potentiation effects of antifungals' and antibacterials' activities by low MW natural products mainly on polyphenols and terpenes were reported in the literature and, in spite of that most works included only in vitro assays, this knowledge opens a wide range of possibilities for the combination antimicrobial therapy. Further research including in vivo assays and clinical trials are required to determine the relevance of these antimicrobial enhancers in the clinical area and should be the focus of future studies in order to develop new antimicrobial combination agents that overpass the drawbacks of the existing antibiotics and antifungals in clinical use. PMID- 29174959 TI - Blind versus ultrasound-guided maxillary nerve block in donkeys. AB - OBJECTIVES: To describe the 'blind' and ultrasound-guided approaches to block the maxillary nerve in donkeys. To compare the success and complication rates between the 'blind' and ultrasound-guided techniques based on staining of nerves and other structures in cadavers and assessing level of analgesia in live animals. STUDY DESIGN: Prospective anatomical and experimental study. ANIMALS: Eighteen cadaver heads and nine adult live donkeys. METHODS: Phase 1: the anatomical characteristics of the maxillary nerve and its related structures were investigated within the pterygopalatine fossa in five cadavers. Phase 2: 0.1 mL of methylene blue dye was injected blindly and via ultrasound guidance in 13 cadavers to stain the left and right maxillary nerves, respectively. Nerve staining and dye spreading were evaluated through cadaver dissection. Phase 3: the former procedures were applied in nine live donkeys using lidocaine hydrochloride 2% and the onset of analgesia was verified through needle pricking at the naris. RESULTS: Ultrasound-guided deposition of methylene blue dye in cadavers and lidocaine injection in live animals were successful in all instances (accuracy = 100%) without inadvertent vascular penetration. Using the 'blind' technique, misdirection and intravascular deposition of dye were reported in four cadavers (accuracy = 69.2%) and neurovascular trauma was observed in live donkeys (five cases). Loss of cutaneous sensation in the ipsilateral naris was earlier in the ultrasound-guided approach (10.9 +/- 1.8 minutes) than in the 'blind' technique (27.8 +/- 3.2 minutes; p < 0.001). CONCLUSIONS AND CLINICAL RELEVANCE: An ultrasound-guided maxillary nerve blockade proved very practical and can be used to block the maxillary nerve with a high degree of accuracy while avoiding vascular penetration. Further studies are mandatory to validate its analgesic effectiveness in clinical situations. PMID- 29174960 TI - The uptake of transdermal fentanyl in a pregnant sheep model. AB - OBJECTIVE: To evaluate the maternal and foetal uptake of transdermal fentanyl patch applied to the groin of pregnant sheep following surgery. STUDY DESIGN: Prospective series. ANIMALS: A group of 16 singleton pregnant sheep underwent anaesthesia for laparotomy, hysterotomy and instrumentation of the foetus. Of these ewes 10 (101 +/- 12 days of gestation) were used to evaluate the maternal uptake of transdermal fentanyl, and the efficacy of the drug in the postoperative period (n = 10). To determine the extent of transplacental transfer of fentanyl, six ewes from the group of 10, and six other ewes (92 +/- 1 days' gestation) were studied. METHODS: A 75 MUg hour-1 fentanyl patch was placed onto the woolless skin of the medial thigh close to the groin at the end of surgery. Maternal blood samples were collected from the cephalic or jugular vein, and pain and sedation scores were determined, prior to application of the patch (time 0) and at 3, 6, 12, 24, 36 and 48 hours after. A commercial Fentanyl ELISA kit was used to determine the concentration of fentanyl. Paired maternal and foetal blood samples were collected 48 hours after surgery. Animals were euthanized at the end of the study. Data were tested for normality and compared with Student t test or one-way anova and are expressed as mean +/- standard deviation or median (range). RESULTS: Recovery from anaesthesia and surgery was uneventful in all ewes. The dose of fentanyl was 1.4 +/- 0.2 MUg kg-1 hour-1. The maximum maternal plasma concentration of fentanyl was 0.547 ng mL-1 (range, 0.349-0.738 ng mL-1) at 12 hours. After 48 hours, the concentration of fentanyl was 0.381 ng mL-1 (range, 0.211-0.487 ng mL-1; maternal) and 0.295 ng mL-1 (range, 0.185-0.377 ng mL-1; foetal; p = 0.175). The placental transfer rate of fentanyl was 77%. CONCLUSIONS AND CLINICAL RELEVANCE: The uptake of fentanyl varied between animals. The placental transfer rate of fentanyl was 77%. PMID- 29174961 TI - Effect of premedication with butorphanol or methadone on ease of endoscopic duodenal intubation in dogs. AB - OBJECTIVE: The effect of premedication with butorphanol or methadone on ease of endoscopic duodenal intubation. STUDY DESIGN: Prospective, randomized, blinded clinical trial. ANIMALS: A group of 20 client-owned dogs. METHODS: Dogs were assigned randomly to be administered intravenous (IV) premedication with either butorphanol (0.4 mg kg-1) or methadone (0.3 mg kg-1). General anaesthesia was induced with propofol to effect and maintained with isoflurane in 100% oxygen. Sedation score 20 minutes after premedication administration and induction dose of propofol were recorded. Heart rate, mean arterial pressure, haemoglobin oxygen saturation, respiratory rate and end-tidal isoflurane concentration were recorded every 5 minutes. Spontaneous lower oesophageal and pyloric sphincter opening, presence of gastro-oesophageal and duodeno-gastric reflux, antral peristaltic contractions and response to endoscopy were recorded as yes or no. Ease of duodenal intubation (EDI) was graded on a scale ranging from 1 (immediate entry with minimal manoeuvring required) to 4 (no entry after 2 minutes). Time (seconds) from the start of pyloric intubation to successfully entering the duodenum was recorded. RESULTS: Median EDI score [3 +/- 1 (butorphanol), 4 +/- 1 (methadone), p = 0.035], time [65 +/- 36 seconds (butorphanol), 120 +/- 38 seconds (methadone), p = 0.028] and number of dogs with spontaneous pyloric sphincter opening [7/10 (butorphanol), 2/10 (methadone), p = 0.035] differed between groups. No other significant differences were found. CONCLUSIONS AND CLINICAL RELEVANCE: In these clinical cases, duodenal intubation was performed with greater ease, shorter time and more frequent spontaneous opening of the pyloric sphincter after premedication with butorphanol in comparison to methadone. The use of butorphanol facilitated the passage of the endoscope and is therefore recommended for premedication prior to upper gastrointestinal tract endoscopy.

AB - Cluster headache is a trigeminal autonomic cephalalgia characterised by extremely painful, strictly unilateral, short-lasting headache attacks accompanied by ipsilateral autonomic symptoms or the sense of restlessness and agitation, or both. The severity of the disorder has major effects on the patient's quality of life and, in some cases, might lead to suicidal ideation. Cluster headache is now thought to involve a synchronised abnormal activity in the hypothalamus, the trigeminovascular system, and the autonomic nervous system. The hypothalamus appears to play a fundamental role in the generation of a permissive state that allows the initiation of an episode, whereas the attacks are likely to require the involvement of the peripheral nervous system. Triptans are the most effective drugs to treat an acute cluster headache attack. Monoclonal antibodies against calcitonin gene-related peptide, a crucial neurotransmitter of the trigeminal system, are under investigation for the preventive treatment of cluster headache. These studies will increase our understanding of the disorder and perhaps reveal other therapeutic targets. PMID- 29174964 TI - microRNA-212 promotes lipid accumulation and attenuates cholesterol efflux in THP 1 human macrophages by targeting SIRT1. AB - Macrophage foam cell formation is a key initiating event in the pathogenesis of atherosclerosis. This work was conducted to determine the role of microRNA (miR) 212 in the transformation of foam cells from macrophages. We examined the expression of miR-212 in atherosclerotic lesions in an apoE-deficient (apoE-/-) mouse model. The effects of miR-212 overexpression and knockdown on lipid accumulation and cholesterol homeostasis in THP-1 macrophages after exposure to oxidized low-density lipoprotein (oxLDL). The mechanism underlying the activity of miR-212 was explored. It was found that miR-212 was downregulated in atherosclerotic lesions and macrophages from apoE-/- mice fed high-fat diet, compared to the equivalents from apoE-/- mice fed standard diet. Overexpression of miR-212 promoted lipid accumulation in oxLDL-treated THP-1 macrophages, whereas miR-212 depletion exerted an opposite effect. Macrophage cholesterol efflux to apolipoprotein A-I was significantly reduced by miR-212, which was accompanied by reduced ABCA1 expression. Mechanistically, miR-212 targeted sirtuin 1 (SIRT1) to repress the expression of ABCA1 in THP-1 macrophages. Rescue experiments confirmed that co-expression of SIRT1 attenuated lipid accumulation and restored cholesterol efflux in miR-212-overexpressing THP-1 macrophages. Collectively, miR-212 facilitates macrophage foam cell formation and suppresses ABCA1-dependent cholesterol efflux through downregulation of SIRT1. Targeting miR 212 may provide a potential therapeutic strategy for atherosclerosis. PMID- 29174965 TI - IL-6 release of Rv0183 antigen-stimulated whole blood is a potential biomarker for active tuberculosis patients. AB - OBJECTIVE: New tests for diagnosing active tuberculosis (aTB) are urgently needed, and TB antigen-specific cell-mediated immunity can be expected to develop new testing methods of aTB. MATERIALS AND METHODS: Rv0183 protein, the only monoglyceride lipase identified in mycobacteria, was used to stimulate freshly heparin-treated whole blood. The Rv0183-specific cytokines/chemokines response associated with aTB was screened firstly with 4 aTB patients and 4 LTBIs, and further evaluated in 192 suspected aTB patients and 372 healthy individuals. RESULTS: Out of 71 cytokines/chemokines, the response of IL-6 against Rv0183 protein was found to be associated with aTB. The Rv0183-specific IL-6 response was significantly higher in aTB patients (n = 128) than in those with non-TB lung disease (n = 64) and in healthy individuals (n = 327) (p < 0.0001), and not affected by latent TB infection. In IGRA+ suspected active TB patients, the sensitivity, specificity, PPV and NPV of IL-6 response (with cutoff of 235.2 pg/ml) were 85.7%, 100%, 100% and 51.5% for diagnosing aTB, respectively. While in IGRA- ones, they were 87.5%, 80.5%, 60.9% and 95.0% with 174.2 pg/ml IL-6 response as cutoff, respectively. CONCLUSIONS: These results clearly show that the Rv0183 antigen-specific IL-6 response has the potential to be used as an immune-diagnosis test for active TB in clinical practice. PMID- 29174966 TI - Pentraxin-3 as a marker of sepsis severity and predictor of mortality outcomes: A systematic review and meta-analysis. AB - OBJECTIVES: Pentraxin-3 (PTX-3) is a multi-functional pattern recognition molecule produced by various cell types of peripheral tissues in different infections. It is raised in sepsis, but its values in predicting disease severity or mortality outcomes have been controversial. Therefore, we conducted a systematic review and meta-analysis of these associations. METHODS: PubMed and Embase were searched until July 18, 2017 for studies that evaluated the relationship between PTX-3 levels and disease severity or mortality in sepsis. RESULTS: A total of 23 and 10 entries were retrieved from both databases, respectively, of which 16 studies were included in the final meta-analysis. A total of 3001 patients (56% male, mean age 63 +/- 15 years; mean follow-up duration of 207 days) were analysed. PTX-3 was significantly higher in patients with more severe sepsis compared to those with less severe sepsis (standard mean difference = 18.5 ng/mL, standard error: 4.5 ng/mL, P < 0.0001) and higher in non survivors compared to survivors (standard mean difference = 40.3 ng/mL, standard error: 6.8 ng/mL, P < 0.0001). Elevated PTX-3 levels significantly increased the risk of all-cause mortality (hazard ratio: 1.91, 95% CI: 1.53 to 2.46, P < 0.0001). CONCLUSIONS: PTX-3 significantly predicts disease severity and mortality in sepsis. PMID- 29174967 TI - False positive serum levels of (1-3)-beta-D-Glucan after infusion of intravenous immunoglobulins and time to normalisation. AB - OBJECTIVES: (1-3)-beta-D-Glucan (BDG) is a marker for invasive fungal diseases (IFD). Administration of intravenous immunoglobulin preparations (IVIG) has been reported to lead to false positive BDG serum levels >80 pg/ml. The aim of the study was to determine the time interval between IVIG infusion and normalisation of BDG serum levels. METHODS: In 22 paediatric haemato-/oncologic patients, we analysed 92 BDG serum levels obtained within 4 weeks after IVIG administration (0.5 to 1 g/kg body weight), correlated them to 54 IVIG episodes and compared them to 76 BDG levels obtained in 29 patients without IVIG administration in the 4 weeks prior to BDG analyses (control group). RESULTS: BDG peak levels within 3 days after IVIG ranged from 21.47 to 660.38 (median 201.4) pg/ml. BDG serum levels at 7, 14 and 21 days (+/-1 day each) after IVIG infusion were significantly higher than BDG serum levels in the control group (p < 0.001 each). By days 7, 14, and 21 (+/-1 day each) after IVIG infusion, BDG serum levels have normalized (<80 pg/ml) in 64.0%, 76.5% and 100%, respectively. CONCLUSIONS: IVIG administration leads to false positive BDG levels in the vast majority of patients. Elevated BDG levels may be detectable for more than two weeks after IVIG administration, while BDG levels normalized within 3 weeks in all patients. Therefore, BDG should not be used to diagnose IFD within three weeks after IVIG administration. PMID- 29174968 TI - Caloric restriction can improve learning and memory in C57/BL mice probably via regulation of the AMPK signaling pathway. AB - Caloric restriction (CR) is effective in slowing aging and delaying aging-related diseases in many species, but the mechanism is complex and not fully elucidated. This study aimed to evaluate the beneficial effects of a caloric restriction diet on learning and memory, and further to elucidate the mechanisms. Thirty-six week old male C57/BL mice were randomly divided into three groups: normal control (NC group), high-energy (HE group) and CR group. After 44weeks, the Morris water maze was used to examine learning and memory abilities. Western blotting and immunohistochemistry were used to detect changes in proteins involved in the adenosine monophosphate-activated protein kinase (AMPK) pathway in the mouse hippocampus. Compared with NC group, the swimming distance and escape latency were shorter in the CR group. The protein and mRNA expression of AMPK and glucose transporter type 4 (GLUT4) in the CR group were significantly higher than that in HE group. CR increased serum insulin-like growth factor, adiponectin and vaspin, decreased blood glucose and serum malondialdehyde, and improved insulin sensitivity. Our findings demonstrate that a CR diet may improve hippocampus dependent spatial learning ability of C57/BL mice, accompanied with an increase in AMPK and GLUT4 expression, which indicates AMPK pathway was associated with the neuroprotective effect of CR in mice. PMID- 29174969 TI - Resveratrol modulates response against acute inflammatory stimuli in aged mouse brain. AB - With upcoming age, the capability to fight against harmful stimuli decreases and the organism becomes more susceptible to infections and diseases. Here, the objective was to demonstrate the effect of dietary resveratrol in aged mice in potentiating brain defenses against LipoPolySaccharide (LPS). Acute LPS injection induced a strong proinflammatory effect in 24-months-old C57/BL6 mice hippocampi, increasing InterLeukin (Il)-6, Tumor Necrosis Factor-alpha (Tnf-alpha), Il-1beta, and C-X-C motif chemokine (Cxcl10) gene expression levels. Resveratrol induced higher expression in those cytokines regarding to LPS. Oxidative Stress (OS) markers showed not significant changes after LPS or resveratrol, although for resveratrol treated groups a slight increment in most of the parameters studies was observed, reaching signification for NF-kB protein levels and iNOS expression. However, Endoplasmic Reticulum (ER) stress markers demonstrated significant changes in resveratrol-treated mice after LPS treatment, specifically in eIF2alpha, BIP, and ATF4. Moreover, as described, resveratrol is able to inhibit the mechanistic Target of Rapamycin (mTOR) pathway and this effect could be linked to (eIF2alpha) phosphorylation and the increase in the expression of the previously mentioned proinflammatory genes as a response to LPS treatment in aged animals. In conclusion, resveratrol treatment induced a different cellular response in aged animals when they encountered acute inflammatory stimuli. PMID- 29174970 TI - Selective isolation and noninvasive analysis of circulating cancer stem cells through Raman imaging. AB - Circulating cancer stem cells (CCSCs), a rare circulating tumor cell (CTC) type, recently arose as a useful resource for monitoring and characterizing both cancers and their metastatic derivatives. However, due to the scarcity of CCSCs among hematologic cells in the blood and the complexity of the phenotype confirmation process, CCSC research can be extremely challenging. Hence, we report a nanoparticle-mediated Raman imaging method for CCSC characterization which profiles CCSCs based on their surface marker expression phenotypes. We have developed an integrated combinatorial Raman-Active Nanoprobe (RAN) system combined with a microfluidic chip to successfully process complete blood samples. CCSCs and CTCs were detected (90% efficiency) and classified in accordance with their respective surface marker expression via completely distinct Raman signals of RANs. Selectively isolated CCSCs (93% accuracy) were employed for both in vitro and in vivo tumor phenotyping to identify the tumorigenicity of the CCSCs. We utilized our new method to predict metastasis by screening blood samples from xenograft models, showing that upon CCSC detection, all subjects exhibited liver metastasis. Having highly efficient detection and noninvasive isolation capabilities, we have demonstrated that our RAN-based Raman imaging method will be valuable for predicting cancer metastasis and relapse via CCSC detection. Moreover, the exclusion of peak overlapping in CCSC analysis with our Raman imaging method will allow to expand the RAN families for various cancer types, therefore, increasing therapeutic efficacy by providing detailed molecular features of tumor subtypes. PMID- 29174971 TI - A self-powered biosensing device with an integrated hybrid biofuel cell for intermittent monitoring of analytes. AB - In this work, we propose an integrated self-powered sensing system, driven by a hybrid biofuel cell (HBFC) with carbon paper discs coated with multiwalled carbon nanotubes. The sensing system has a biocathode made from laccase or bilirubin oxidase, and the anode is made from a zinc plate. The system includes a dedicated custom-built electronic control unit for the detection of oxygen and catechol analytes, which are central to medical and environmental applications. Both the HBFC and sensors, operate in a mediatorless direct electron transfer mode. The measured characteristics of the HBFC with externally applied resistance included the power-time dependencies under flow cell conditions, the sensors performance (evaluated by cyclic voltammetry), and chronoamperometry. The HBFC is integrated with analytical devices and operating in a pulse mode form long-run monitoring experiments. The HBFC generated sufficient power for wireless data transmission to a local computer. PMID- 29174972 TI - A novel electrochemical sensor based on Cu@Ni/MWCNTs nanocomposite for simultaneous determination of guanine and adenine. AB - A novel electrochemical sensing platform based on combination of multi-walled carbon nanotubes and copper-nickel hybrid nanoparticles (Cu@Ni/MWCNTs) was developed for simultaneous detection of guanine (G) and adenine (A). The Ni/MWCNTs and Cu@Ni/MWCNTs nanocomposites were characterized by transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDS). The electrochemical behaviors of G and A on the modified electrode were explored by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) in phosphate buffer with pH 3.0. Under the optimal conditions, electrical signals were linear over the concentration ranges from 5.0 to 180MUM and 8.0 to 150MUM for simultaneous determination G and A with the detection limit as low as 0.35MUM and 0.56MUM (S/N = 3), respectively. Furthermore, linear concentration ranges in individual determination are 1.0-180MUM and 2.0-150MUM with detection limits of 0.17MUM and 0.33MUM (S/N = 3) for G and A, respectively. The sensor was successfully used to quantify G and A in real samples. The Cu@Ni/MWCNTs composite presented here can serve as a promising candidate for developing electrochemical sensor devices and plays an important role in widespread fields. PMID- 29174973 TI - A novel screen-printed mast cell-based electrochemical sensor for detecting spoilage bacterial quorum signaling molecules (N-acyl-homoserine-lactones) in freshwater fish. AB - A novel screen-printed cell-based electrochemical sensor was developed to assess bacterial quorum signaling molecules, N-acylhomoserine lactones (AHLs). Screen printed carbon electrode (SPCE), which possesses excellent properties such as low cost, disposable and energy-efficient, was modified with multi-walled carbon nanotubes (MWNTs) to improve electrochemical signals and enhance the sensitivity. Rat basophilic leukemia (RBL-2H3) mast cells encapsulated in alginate/graphene oxide (NaAgl/GO) hydrogel were immobilized on the MWNTs/SPCE to serve as recognition element. Electrochemical impedance spectroscopy (EIS) was employed to record the cell impedance signal as-influenced by Pseudomonas aeruginosa quorum sensing molecule, N-3-oxododecanoyl homoserine lactone (3OC12-HSL). Experimental results show that 3OC12-HSL caused a significant decrease in cell viability in a dose dependent manner. The EIS value decreased with concentrations of 3OC12-HSL in the range of 0.1-1MUM, and the detection limit for 3OC12-HSL was calculated to be 0.094MUM. These results were confirmed via cell viability, SEM, TEM analysis. Next, the sensor was successfully applied to monitoring the production of AHLs by spoilage bacteria in three different freshwater fish juice samples which efficiently proved the practicability of this cell based method. Therefore, the proposed cell sensor may serve as an innovative and effective approach to the measurement of quorum signaling molecule and thus provides a new avenue for real time monitoring the spoilage bacteria in freshwater fish production. PMID- 29174974 TI - m-Trifluoromethyl-diphenyl diselenide promotes resilience to social avoidance induced by social defeat stress in mice: Contribution of opioid receptors and MAPKs. AB - Depressive symptoms precipitated by stress are prevalent in population. In experimental models of social stress, endogenous opioids mediate different aspects of defensive and submissive behaviors. The present study investigated the opioid receptors, mitogen-activated protein kinase (MAPKs) and protein kinase B (Akt) contribution to m-trifluoromethyl-diphenyl diselenide [(m-CF3-PhSe)2] effects on social avoidance induced by social defeat stress (SDS). Adult Swiss mice were subjected to SDS and treated with (m-CF3-PhSe)2 (5 to 25mg/kg) for 7days. After that, the mice performed locomotor and social avoidance tests. The opioid receptors, MAPKs and Akt protein contents were determined in the prefrontal cortical samples of mice. Firstly, the mice were segregated in susceptible or resilient subpopulation based on their social avoidance induced by stress. (m-CF3-PhSe)2 (25mg/kg) was effective against the stress-induced social avoidance and improved social interaction behavior in mice. SDS increased the MU and kappa protein contents but reduced those of delta opioid receptors in susceptible mice. Resilient and (m-CF3-PhSe)2-treated mice had no alteration in the levels of opioid receptors. Moreover, (m-CF3-PhSe)2 was effective against the increase of c-Jun N-terminal kinase (JNK) and the decrease of Akt phosphorylation protein contents induced by SDS in susceptible mice. The protein content of extracellular signal-regulated kinase (ERK) phosphorylation was reduced in both susceptible and resilient mice, whereas p38 mitogen-activated protein kinase (p38 MAPK) phosphorylation was increased only in resilient mice. (m-CF3-PhSe)2 was partially effective against the pERK decrease and ineffective against the increase in p38 MAPK phosphorylation in mice subjected to SDS. These results suggest that the modulation of protein contents of opioid receptors, JNK and Akt phosphorylation is associated with resilience to SDS promoted by (m-CF3-PhSe)2 in mice. PMID- 29174975 TI - Consumers' perceptions of biocidal products in households. AB - Biocidal products are commonly used in households and can pose a risk to human health and the environment. The aim of this study was to evaluate consumers' use and understanding of biocidal products in order to identify starting points for minimising their exposure to these products and reducing possible emissions to the environment. In a case study, standardised questionnaires were used to interview consumers in 133 households in three neighbourhoods in Northern Germany, representing the urban-rural typologies in Europe: predominantly urban, intermediate and predominantly rural regions. The questions focussed on the comprehension of the term 'biocide', pest control habits, sources of information, risk perception of different product groups and possible emission reduction measures. Only 21% of the respondents understood the term 'biocide' correctly, whereas 29% thought of 'something that had to do with organic pest control', and 28% were not able to think of a possible meaning. The risk perception of biocidal products compared to plant protection products varied depending on the living conditions. In the urban neighbourhood, biocidal products were perceived as more dangerous than in the rural area. The main pests to be fought were ants, mould and fruit fly. The results of the study indicate that there is a considerable difference between the types of biocidal products that interviewees claimed to own and those that they actually did have in their households. Most notably, respondents did not realise that they owned surface disinfectants. This result indicates that consumers often seem not to be aware of using specific biocidal products. Also, this shows the limitations of collecting data on products owned with only one method, as the results from products inventories of the households deviate from the data collected in interviews. Our results show that the term 'biocide' is not fully understood by many people. To communicate possible risks of biocidal products, other terms would have to be used. Online information regarding general facts on necessary general hygiene measures and biocidal products against bacteria and insects are likely to be of highest relevance for consumers. However, risk communication for biocidal products in general is difficult because consumers are often not aware of using biocidal products. For this reason, information and awareness raising campaigns should be accompanied by further measures such as sales restrictions for specific user-groups or prohibitions of certain uses for a sustainable use of biocidal products. PMID- 29174976 TI - Deposition pattern of aerosolized Legionella using an ex vivo human-porcine respiratory model. AB - Legionella are bacteria responsible for severe lung pathologies. However how they enter and are deposited within the respiratory tract remains poorly documented. Data using animal testing led to the establishment of mathematical models allowing the estimation of aerosol dispersion risks. But direct extrapolation to humans is questionable and experimental models more physiologically representative of the inhalation route are welcome. The aim of this study was to develop a model as close as possible to the human anatomy and physiology allowing determining the deposition pattern of aerosolized Legionella while limiting in vivo experiments. To that purpose, we adapted the chimeric respiratory tract model we previously developed. This original model consisted of a replica of the human upper respiratory airways made by additive manufacturing connected to ex vivo porcine lungs ventilated by passive expansion, as for humans in physiological conditions. These experiments didn't imply specific animal sacrifices as pigs were bred for human consumption and lungs were considered as wastes by the slaughterhouse. Fluorescent Legionella were aerosolized and visualized using Cellvizio(r) Lab (probe-based confocal fluorescence microscope). Legionella were found in the whole respiratory tract. Broncho-alveolar lavages were also performed and the amount of Legionella reaching the thoracic region was quantified by culture and qPCR. Legionella were found preferentially in the left upper lobe compared to the right lower lobe. To our knowledge, it is the first time that experiments mimicking so closely human exposure by inhalation are performed while limiting animal experiments and providing a model for further Legionella infectious risk assessment. PMID- 29174977 TI - Generation of an induced pluripotent stem cell line from a 39-year-old female patient with severe-to-profound non-syndromic sensorineural hearing loss and a A1555G mutation in the mitochondrial MTRNR1 gene. AB - Sensorineural hearing loss (SNHL) is a prevalent form of deafness commonly arising from damage to the cochlear sensory hair cells and degeneration of the spiral ganglion neurons. In this study, Sendai virus was used to generate an induced pluripotent stem cell (iPSC) line from a 39-year-old female patient diagnosed with severe-to-profound, non-syndromic SNHL. The patient also carries a A1555G mutation in the mitochondrial 12S ribosome RNA gene (MTRNR1). This iPSC line was verified to express pluripotent markers, possess normal karyotype, harbor the specific mutation and demonstrated the capacity to differentiate into three germ layers. PMID- 29174978 TI - Transcription pausing regulates mouse embryonic stem cell differentiation. AB - The pluripotency of embryonic stem cells (ESCs) relies on appropriate responsiveness to developmental cues. Promoter-proximal pausing of RNA polymerase II (Pol II) has been suggested to play a role in keeping genes poised for future activation. To identify the role of Pol II pausing in regulating ESC pluripotency, we have generated mouse ESCs carrying a mutation in the pause inducing factor SPT5. Genomic studies reveal genome-wide reduction of paused Pol II caused by mutant SPT5 and further identify a tight correlation between pausing mediated transcription effect and local chromatin environment. Functionally, this pausing-deficient SPT5 disrupts ESC differentiation upon removal of self-renewal signals. Thus, our study uncovers an important role of Pol II pausing in regulating ESC differentiation and suggests a model that Pol II pausing coordinates with epigenetic modification to influence transcription during mESC differentiation. PMID- 29174979 TI - MicroRNA-30e-5p suppresses non-small cell lung cancer tumorigenesis by regulating USP22-mediated Sirt1/JAK/STAT3 signaling. AB - MicroRNA-30e-5p (miR-30e-5p) is a tumor suppressor that is known to be downregulated in non-small cell lung cancer (NSCLC). However, how miR-30e-5p inhibits NSCLC tumorigenesis is not known. Ubiquitin-specific peptidase 22 (USP22) is upregulated in NSCLC and promotes tumorigenesis via a Sirt1-JAK-STAT3 pathway. In this study, we investigated whether miR-30e-5p inhibits tumor growth by targeting USP22 in NSCLC. Our results reveal that miR-30e-5p expression was correlated negatively with USP22 in NSCLC tissues. Luciferase reporter assays showed that miR-30e-5p negatively regulated USP22 expression by binding to a specific sequence in the 3'UTR. MiR-30e-5p overexpression and USP22 knockdown significantly inhibited tumor growth in vivo and induced cell cycle arrest and apoptosis in NSCLC cells in vitro. The effects of miR-30e-5p inhibition were prevented by USP22 knockdown. MiR-30e-5p inhibited SIRT1 expression and increased expression of p53 and the phosphorylated form of STAT3 (pSTAT3). Furthermore, miR 30e-5p prevented USP22-mediated regulation of SIRT1, pSTAT3, and p53 expression. Taken together, these findings suggest that miR-30e-5p suppresses NSCLC tumorigenesis by downregulatingUSP22-mediated Sirt1/JAK/STAT3 signaling. Our study has identified miR-30e-5p as a potential therapeutic target for the treatment of NSCLC. PMID- 29174980 TI - PDGF-mediated PI3K/AKT/beta-catenin signaling regulates gap junctions in corpus cavernosum smooth muscle cells. AB - Erectile dysfunction (ED) is the most common sexual disorder that men report to healthcare providers. Gap junctions (GJs) are thought to be responsible for synchronous shrinkage of corpus cavernosum smooth muscle cells (CCSMCs), and play thus an important role in the maintenance of an erection. Hypoxia has been suggested as a pathological mechanism underlying ED. Here we demonstrate that hypoxia increased the expression of platelet-derived growth factor (PDGF) and the main GJ component connexin (Cx)43 in CCSMCs. Inhibiting PDGF receptor (PDGFR) activity decreased Cx43 expression. Treatment with different concentrations of PDGF increased the levels of phosphorylated protein kinase B (AKT), beta-catenin, and Cx43, whereas inhibition of PDGFR or activation of phosphatidylinositol 3 kinase (PI3K)/AKT signaling altered beta-catenin and Cx43 expression. Meanwhile, silencing beta-catenin resulted in the downregulation of Cx43. These results demonstrate that PDGF secretion by CCSMCs and vascular endothelial cells is enhanced under hypoxic conditions, leading to increased Cx43 expression through PI3K/AKT/beta-catenin signaling and ultimately affecting GJ function in ED. Thus, targeting this pathway is a potential therapeutic strategy for the treatment of ED.

AB - Tumor cells often encounter hypoglycemic microenvironment due to rapid cell expansion. It remains elusive how tumors reprogram the genome to survive the metabolic stress. The tumor suppressor TIP60 functions as the catalytic subunit of the human NuA4 histone acetyltransferase (HAT) multi-subunit complex and is involved in many different cellular processes including DNA damage response, cell growth and apoptosis. Attenuation of TIP60 expression has been detected in various tumor types. The function of TIP60 in tumor development has not been fully understood. Here we found that suppressing TIP60 inhibited p53 K120 acetylation and thus rescued apoptosis induced by glucose deprivation in hepatocellular cancer cells. Excitingly, Lys-104 (K104), a previously identified lysine acetylation site of TIP60 with unknown function, was observed to be indispensable for inducing p53-mediated apoptosis under low glucose condition. Mutation of Lys-104 to Arg (K104R) impeded the binding of TIP60 to human NuA4 complex, suppressed the acetyltransferase activity of TIP60, and inhibited the expression of pro-apoptotic genes including NOXA and PUMA upon glucose starvation. These findings demonstrate the critical regulation of TIP60/p53 pathway in apoptosis upon metabolic stress and provide a novel insight into the down-regulation of TIP60 in tumor cells.

AB - Diffuse large B cell lymphoma (DLBCL) is a common B cell malignancy with approximately 30% of patients present relapsed or refractory disease after first line therapy. Research of further treatment options is needed. Cytotoxic CD4+ T cells express cytolytic molecules and have potential antitumor function. Here, we showed that the CD19+ cells from DLBCL patients presented significantly reduced expression of MHC II molecules than those from healthy controls. Three years after the first-line treatment, patients that presented relapsed disease had significantly lower MHC II expression on their CD19+ cells than patients who did not show recurrence. Examining cytotoxic CD4+ T cells show that DLBCL patients presented significantly elevated frequencies of granzyme A-, granzyme B-, and/or perforin-expressing cytotoxic CD4+ T cells. Also, frequency of cytotoxic CD4+ T cells in DLBCL patients was positively correlated with the MHC II expression level. Subsequently, the cytotoxic potential of CD4+ T cells against autologous CD19+ cells was investigated. We found that the cytotoxic potential of CD4+ T cells was highest in MHC II-high, intermediate in MHC II-mid, and lowest in MHC II-low patients. The percentage of MHC II-expressing viable CD19+ cells presented a significant reduction after longer incubation with cytotoxic CD4+ T cells, suggesting that cytotoxic CD4+ T cells preferentially eliminated MHC II expressing CD19+ cells. Blocking MHC II on CD19+ cells significantly reduced the cytolytic capacity of CD4+ T cells. Despite these discoveries, the frequency of cytotoxic CD4+ T cells did not predict the clinical outcome of DLBCL patients. Together, these results demonstrated that cytotoxic CD4+ T cells presented an MHC II-dependent cytotoxic potential against autologous CD19+ cells and could potentially represent a future treatment option for DLBCL. PMID- 29174983 TI - Comparison of hepatic transcriptome profiling between acute liver injury and acute liver failure induced by acetaminophen in mice. AB - Acetaminophen (APAP) overdose is a leading cause of drug-induced acute liver failure in many countries. In the present study, we developed stable mouse models of acute drug-induced hepatic injury (DILI) and acute drug-induced hepatic failure (DILF) by sub-lethal and lethal APAP injection respectively. The differences in hepatic transcriptome profiling between these two models were compared by RNA sequencing, which were validated by qPCR, western-blot and ELISA. In results, serum IL-6, TNF-a and IL-10 levels are higher in DILF than in DILI. The upregulated genes in DILF compared with DILI were mostly enriched in the areas of "cellular development process", "cell division", "multicellular organism development," etc. The downregulated genes in DILF compared with DILI were mostly enriched in the areas of "cellular response to chemical stimulus", "cellular response to stress", "cell activation," etc. Sub-lethal doses of APAP increased Myc, Bag3 and Btc expression in mouse liver, but lethal doses of APAP did not, which suggested that these three genes might play important roles in adaptive protection reactions in DILI. The serum Btc level might be a potential biomarker of drug induced liver injury with good prognosis. Our data can help us better understand the mechanisms of hepatotoxicity that influence prognosis and seek novel prognostic indicators of DILI. PMID- 29174984 TI - Efficacy of anti-inflammatory, antibiotic and pleiotropic agents in reversing nitrogen mustard-induced injury in ex vivo cultured rabbit cornea. AB - Vesicating agent, Sulfur mustard (SM), causes devastating eye injury; however, there are no effective antidotes available. Using nitrogen mustard (NM), a bi functional analog of SM, we have earlier reported that NM-induced corneal injury in ex vivo rabbit cornea organ culture model parallels corneal injury reported with SM. Using this model, we have demonstrated the therapeutic efficacy of dexamethasone (DEX), doxycycline (DOX) and silibinin (SB) in reversing NM (2h exposure)-induced corneal injuries when added immediately after washing NM. In the present study, we further examined the efficacy of similar/higher doses of these agents when added immediately, 2, or 4h after washing NM following its 2h exposure. All three treatment agents caused a reversal in established NM-induced injury biomarkers when added immediately or 2h after washing NM following its 2h exposure; however, when treatments were carried out 4h after washing NM, there was no significant effect. Together, our results further show the beneficial effect of these agents in reversing NM-induced corneal injury and indicate the time window for effective treatment. This could be useful towards future development of targeted therapeutics against vesicant-induced ocular injury. PMID- 29174985 TI - Role of P-glycoprotein in deoxynivalenol-mediated in vitro toxicity. AB - Deoxynivalenol (DON) is the most prevalent mycotoxin produced by grain-infecting Fusarium strains and frequently occurs in small cereals all over the world. After ingestion, DON is absorbed in the gut, which leads dose-dependently to critical health effects. In the present study, we have further investigated DON's previously reported affinity to the efflux transporter P-glycoprotein (Pgp) in the apical enterocyte membrane. Interaction with Pgp was studied in human colorectal adenocarcinoma (Caco-2) cells and Madin-Darby Canine Kidney wild-type (MDCKII-wt) and Pgp-overexpressing (MDCKII-MDR1) cells in different transport and cytotoxicity experiments. We found that DON was exported by Pgp and was less cytotoxic in Pgp-overexpressing cells. In the fluorometric calcein acetoxymethylester (Calcein AM) assay DON reduced intracellular calcein retention, indicating a stimulation of Pgp-mediated efflux. In the presence of the selective Pgp inhibitors verapamil (Ver) and valspodar (PSC 833) the effect was, respectively, distinctive and significant. Verrucarol, a structural analogue of DON, was much less effective indicating the importance of the alpha, beta conjugated carbonyl group in the DON molecule for Pgp interaction. Our results confirmed that Pgp might have the potential to reduce intestinal absorption of DON in vivo. Furthermore, we were able to show that DON can modulate Pgp activity in vitro. PMID- 29174986 TI - Correlation between glucuronidation and covalent adducts formation with proteins of nonsteroidal anti-inflammatory drugs. AB - Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause idiosyncratic liver injury. Mechanisms involved in NSAID-induced liver injury are complex. Previous studies have suggested that acyl glucuronide of NSAIDs (NSAIDs-Glu) plays an important role in the development of liver injury via covalently binds to proteins and the resultant adduct induces immunological toxicity. As only some NSAIDs-Glu are commercially available, the evaluation of covalent protein adduct formation using ready-made NSAIDs-Glu is difficult and inconvenient. Moreover, glucuronidation potency varies with the NSAID, including stereoisomers. Therefore, in this study, we simultaneously examined the glucuronidation and covalent adduct formation using enantiomers of parent NSAIDs (ibuprofen, naproxen, pranoprofen, ketoprofen, and flurbiprofen) in rat liver microsomes. Glucuronides and covalent adducts were quantified by HPLC. The amount of covalent adduct increased with NSAIDs-Glu formation in the rat liver microsomes in a time dependent manner. A significant positive correlation was observed between the AUC of NSAIDs-Glu and that of covalent adduct, except ketoprofen. Although ketoprofen exhibited the highest glucuronidation rate among the NSAIDs investigated, the amount of covalent adduct was similar to that for pranoprofen, which had the lowest glucuronidation rate. Thus, it may be difficult for ketoprofen glucuronide to covalently bind with proteins in the rat liver microsomes. Our results suggested that the amount of glucuronide formed is a key factor in predicting covalent bond formation with protein in NSAIDs, in addition to degradability and bindability with proteins of NSAIDs-Glu. Further studies are required to confirm the relationship between the tendency of glucuronidation and the formation of covalent adducts of NSAIDs. PMID- 29174987 TI - Drug-excipient compatibility assessment of solid formulations containing meloxicam. AB - Meloxicam (MLX) is a non-steroidal anti-inflammatory cyclooxygenase (COX) inhibitor that is used to relieve inflammation and pain. MLX has a preferential affinity for COX-2, which is associated with a lower incidence of gastrointestinal side effects. The drug belongs to Class II of the Biopharmaceutical Classification System (BCS) in which dissolution is the limiting step of its bioavailability. In view of this classification, carrying out further studies regarding the compatibility of MLX with excipients and the mechanisms and kinetics of its degradation reactions is fundamental because any changes would directly influence the quality of the product. The aim of the present work is to evaluate solid pharmaceutical formulations containing MLX found on the market to define the more suitable excipients to improve the stability of the pharmaceutical formulations. Thermal analysis techniques were used to characterize and evaluate the compatibility between the drug and the excipients present in the market formulations. In the evaluation of its solid state kinetics, MLX raw material under inert conditions had a shelf life of approximately 6years. In the study of compatibility between the drug and excipients, MLX was found to be incompatible with magnesium stearate after DSC analysis under binary mixtures, which was confirmed by stress studies and chromatographic analyzes. PMID- 29174988 TI - Synthesis and characterization of IUdR loaded PEG/PCL/PEG polymersome in mixed DCM/DMF solvent: Experimental and molecular dynamics insights into the role of solvent composition and star architecture in drug dispersion and diffusion. AB - Combined experimental and simulation investigations have provided molecular level insights into 5-iodo-2'-deoxyuridine (IUdR) loading behavior for the novel PEG/PCL/PEG polymersome-like carriers in mixed dichloromethane/N,N dimethylformamide (DCM/DMF) solvent. As with the experiments, a novel approach was applied for layer by layer tailoring of polyethylene glycol (PEG) and polycaprolactone (PCL) as PEG/PCL/PEG copolymer on the surface of magnetite nanoparticles (MNPs) by click chemistry. Experimental results indicated that IUdR, as an anti-cancer drug, could be encapsulated up to 80% EE in this nanocarrier and could be in-vitro released up to 90% during 120h. Computational studies, on the other hand, provide molecular level insights into the optimal performance of the carrier in terms of drug "Dispersion" and "Diffusion" patterns in equimolar DCM/DMF solvent. Molecular dynamics simulations of the system in four distinct solvation scenarios including pure DCM, mixed DCM/DMF, pure DMF and water, have proven that while hydrophobic solvents give rise to better "dispersion" of drugs, hydrophilic solvents lead for drug molecules to penetrate into the carrier and improve "diffusion" properties. Optimal conditions for drug encapsulation, as also confirmed through experiments, was observed for mixed DCM/DMF solvent in terms of proper diffusion and well dispersion. While drug "aggregates" were observed in DCM, poorly stable drug molecules with lowered penetrations were observed in pure DMF. Proper release properties with IUdR molecules staying on the surface of the carrier was also observed in water. The interesting role of the star-linear architecture was further scrutinized through distinctions made through analysis of interactions between IUdR molecules with "inner" and "outer" PEG sections. PMID- 29174989 TI - Adsorption of heavy metals on conventional and nanostructured materials for wastewater treatment purposes: A review. AB - The problem of water pollution is of a great concern. Adsorption is one of the most efficient techniques for removing noxious heavy metals from the solvent phase. This paper presents a detailed information and review on the adsorption of noxious heavy metal ions from wastewater effluents using various adsorbents - i.e., conventional (activated carbons, zeolites, clays, biosorbents, and industrial by-products) and nanostructured (fullerenes, carbon nanotubes, graphenes). In addition to this, the efficiency of developed materials for adsorption of the heavy metals is discussed in detail along with the comparison of their maximum adsorption capacity in tabular form. A special focus is made on the perspectives of further wider applications of nanostructured adsorbents (especially, carbon nanotubes and graphenes) in wastewater treatment. PMID- 29174990 TI - Peroxidation and unsaturation indices as potential biomarkers of multifarious zinc and copper micro-supplementation in Helix pomatia L. AB - The work is a continuation of two previous studies in which biomarker fatty acids (12 of 56 FA pools) were analysed in Helix pomatia L. after heterogeneous micro supplementation of Zn and Cu (administered in five micro-doses in the form of salts and EDTA and lysine chelates). This time, peroxidation (PI) and unsaturation coefficients (UI) as biomarker were analysed. These indices were calculated based on the FA profile in the foot and hepatopancreas of snails. The correlation of frequently used oxidation status indicators of organisms (catalase - CAT, glutathione peroxidase - GPx, selenium-dependent peroxidase - se-GPx, superoxide dismutase - SOD, glutathione transferase - GST, glutathione reductase GR, glutathione - GSH, carbonyl protein - CP, thiobarbituric acid reactive substances - TBARS) with the rarely used UI and PI ratios was analysed. It was found that the 12-week micro-exposure to Zn and Cu did not inhibit but rather stimulated antioxidative defence at a sufficient level to increase the values of peroxidation/unsaturation indices in comparison to the control groups. Induction of an opposite process to oxidation of fatty acids was demonstrated. Maximum activities and amounts of antioxidants as well as minima of protein and lipid decomposition were recorded in groups supplemented with 0.75mg/l Zn and 1.0mg/l Cu. The possibility of a direct use of fatty acids as well as peroxidation/unsaturation indices as sensitive and reproducible biomarkers of exposure and oxidative physiological status in snails was confirmed. PMID- 29174991 TI - Heavy metal pollution and health risk assessment of agricultural soils in a typical peri-urban area in southeast China. AB - Heavy metal pollution in peri-urban areas in China is serious and complex. We thus developed an integrated evaluation method to assess heavy metal pollution and potential health risk to residents in a typical peri-urban area with diverse anthropogenic emission sources and cropping systems. Ecological risk was evaluated using Nemerow's synthetical pollution index (Pn) and Potential ecological risk index (RI). Then polluted areas and responsible emission sources were identified by GIS mapping. Health risk caused by food intake and soil exposure was calculated by accounting for the influence of anthropogenic emissions and cropping systems. Agricultural soils in the study area were polluted by cadmium (Cd), mercury (Hg), lead (Pb), and arsenic (As). High concentrations mainly occurred near the mining area and along the roadsides. The accumulation of heavy metals in crops followed the order of tea leaves > rice grain > vegetables. The hazard index of potential human health risk caused by chronic soil exposure and food intake was 15.3, indicating obvious adverse health effects. 87.5% of health risk was attributed to food consumption, and significantly varied among different cropping systems with the decreasing order of rice (10.44) >vegetable (2.86) > tea (0.05). The integrated method of ecological and health risk index, which takes consideration of both anthropogenic emission and cropping system can provide a practical tool for evaluating of agricultural soil in the peri-urban area regrading different risk factors. PMID- 29174992 TI - The main factors effecting the efficiency of Zn(II) flotation: Optimum conditions and separation mechanism. AB - In this study, the effects of chemical conditions on the recovery of Zn(II) and water during the ion flotation process were evaluated using a central composite design (CCD) of response surface methodology. The optimum effective parameters including pH, collector and frother concentration were determined. The results showed that the pH and collector concentration were effective factors for the efficiency of Zn(II) flotation. The effects of collector and frother concentration on the characterization of sublate and the complexation of sodium dodecyl sulphate with Zn(II) were studied using scanning electron microscopy coupled with energy dispersive X-ray (SEM/EDX) spectroscopy and Fourier transform infrared (FTIR) spectroscopy. The results show that foam fractionation occurred at a pH of 1.5, 3 and 5.5 and ion flotation at a pH of 8. PMID- 29174993 TI - Application of green compost as amendment in an agricultural soil: Effect on the behaviour of triasulfuron and prosulfocarb under field conditions. AB - Herbicides are essential in agricultural systems for maintaining crop yields, as weeds compromise grain production. Furthermore, the application of organic amendments to soil is an increasingly frequent agricultural practice for avoiding irreversible soil degradation. However, this practice could modify the behaviour of the herbicides applied, with implications for their absorption by weeds. This study evaluated the dissipation, persistence and mobility of the herbicides triasulfuron and prosulfocarb in a sandy clay loam soil unamended and amended with green compost (GC) in a field experiment using single or combined commercial formulations of both herbicides. The study was carried out in experimental plots (eight treatments * three replicates) corresponding to unamended soil and soil amended with GC, untreated and treated with the herbicide formulations Logran(r), Auros(r) and Auros Plus(r) over 100 days. The half-life (DT50) of triasulfuron applied individually was 19.4 days, and increased in the GC-amended soil (46.7 days) due to its higher adsorption by this soil, although non-significant differences between DT50 values were found when it was applied in combination with prosulfocarb. Prosulfocarb dissipated faster than triasulfuron under all the conditions assayed, but non-significant differences were observed for the different treatments. The analysis of the herbicides at different soil depths (0 50 cm) after their application confirmed the leaching of both herbicides to deeper soil layers under all conditions, although larger amounts of residues were found in the 0-10 and 10-20 cm layers. The application of GC to the soil increased the persistence of both herbicides, and prevented the rapid leaching of triasulfuron in the soil, but the leaching of prosulfocarb was not inhibited. The influence of single or combined formulations was observed for triasulfuron, but not for prosulfocarb. The results obtained highlight the interest of obtaining field data to design rational joint applications of GC and herbicides to prevent the possible decrease in their effectiveness for weeds or the risk of water contamination. PMID- 29174994 TI - Learning bundled care opportunities from electronic medical records. AB - OBJECTIVE: The traditional fee-for-service approach to healthcare can lead to the management of a patient's conditions in a siloed manner, inducing various negative consequences. It has been recognized that a bundled approach to healthcare - one that manages a collection of health conditions together - may enable greater efficacy and cost savings. However, it is not always evident which sets of conditions should be managed in a bundled manner. In this study, we investigate if a data-driven approach can automatically learn potential bundles. METHODS: We designed a framework to infer health condition collections (HCCs) based on the similarity of their clinical workflows, according to electronic medical record (EMR) utilization. We evaluated the framework with data from over 16,500 inpatient stays from Northwestern Memorial Hospital in Chicago, Illinois. The plausibility of the inferred HCCs for bundled care was assessed through an online survey of a panel of five experts, whose responses were analyzed via an analysis of variance (ANOVA) at a 95% confidence level. We further assessed the face validity of the HCCs using evidence in the published literature. RESULTS: The framework inferred four HCCs, indicative of (1) fetal abnormalities, (2) late pregnancies, (3) prostate problems, and (4) chronic diseases, with congestive heart failure featuring prominently. Each HCC was substantiated with evidence in the literature and was deemed plausible for bundled care by the experts at a statistically significant level. CONCLUSIONS: The findings suggest that an automated EMR data-driven framework conducted can provide a basis for discovering bundled care opportunities. Still, translating such findings into actual care management will require further refinement, implementation, and evaluation. PMID- 29174995 TI - Evaluation of the new restandardized 25-hydroxyvitamin D assay on the iSYS platform. AB - BACKGROUND: 25-hydroxyvitamin D [25(OH)D] is the most reliable biomarker of vitamin D status, but until now 25(OH)D assays have suffered from inter laboratory and inter-assay discrepancies. In the setting of the international Vitamin D Standardization Program, Immunodiagnostic Systems (IDS) recently reformulated and restandardized the 25(OH)D immunoassay available on the automated iSYS platform. In the present study, we evaluated this new generation of the 25(OH)D immunoassay (IS-2500). METHODS: Repeatability and within laboratory imprecision were verified according to the Clinical and Laboratory Standards Institute EP15-A3. Results from the sera of 63 patients were compared with those obtained with the previous iSYS method (IS-2700S) using Passing-Bablok and Bland-Altman analysis. The prevalence and bias-adjusted kappa (PABAK) coefficient was calculated to assess the agreement of vitamin D status provided by the two iSYS immunoassays. Fourteen Vitamin D External Quality Assessment Scheme (DEQAS) samples were used to evaluate inaccuracy. RESULTS: Using the EP15 A3 protocol, repeatability and within-laboratory imprecision obtained with the new iSYS method were lower than 6% and 8%, respectively. These results are consistent with the manufacturer's claims. In more adverse conditions (50 measurements over 15days with multiple calibrations), the within-laboratory imprecision was 14.8% (39nmol/L) and 7.7% (155nmol/L). 25(OH)D concentrations measured with the new assay showed a strong correlation with those provided by the previous version (r=0.969, p<0.0001). The Passing-Bablok regression equation was as follows: new assay=1.079 x (previous assay) - 3.6nmol/L. The PABAK coefficient of 0.810 reflected almost perfect agreement between the two immunoassays to classify patients according to their vitamin D status (85.7% of agreement). Using DEQAS samples, the mean inaccuracy bias was lower than 5% when the new iSYS method was compared with LC-MS/MS methods and the NIST reference measurement procedure. CONCLUSION: The new generation of the iSYS immunoassay evaluated in this study meets requirements for routinely measuring 25(OH)D levels in clinical laboratories. PMID- 29174996 TI - Infants Born with Down Syndrome: Burden of Disease in the Early Neonatal Period. AB - OBJECTIVE: To evaluate the incidence of direct admission of infants with Down syndrome to the postnatal ward (well newborn nursery) vs the neonatal intensive care unit (NICU), and to describe the incidence of congenital heart disease (CHD) and pulmonary hypertension (PH). STUDY DESIGN: This retrospective cohort study of Down syndrome used the maternal/infant database (2011-2016) at the Rotunda Hospital in Dublin, Ireland. Admission location, early neonatal morbidities, outcomes, and duration of stay were evaluated and regression analyses were conducted to identify risk factors associated with morbidity and mortality. RESULTS: Of the 121 infants with Down syndrome, 54 (45%) were initially admitted to the postnatal ward, but 38 (70%) were later admitted to the NICU. Low oxygen saturation profile was the most common cause for the initial and subsequent admission to the NICU. Sixty-six percent of the infants (80/121) had CHD, 34% (41/121) had PH, and 6% died. Risk factors independently associated with primary NICU admission included antenatal diagnosis of Down syndrome, presence of CHD, PH, and the need for ventilation. CONCLUSIONS: Infants with Down syndrome initially admitted to the postnatal ward have a high likelihood of requiring NICU admission. Overall, high rates of neonatal morbidity were noted, including rates of PH that were higher than previously reported. Proper screening of all infants with Down syndrome for CHD and PH is recommended to facilitate timely diagnoses and potentially shorten the duration of the hospital stay. PMID- 29174997 TI - Is It Necessary to Heat and Humidify Respiratory Gases for Resuscitation in Preterm Infants? PMID- 29174998 TI - Psychosis and Clinical Outcomes in Alzheimer Disease: A Longitudinal Study. AB - OBJECTIVE: Psychotic symptoms are a common feature in Alzheimer disease (AD), occurring in approximately 40% of patients. These symptoms are associated with worse clinical outcomes. Comparatively little research, however, has distinguished delusions and hallucinations, which may have distinct clinical, neuropathological, and genetic correlates. To address this, the current study examined the clinical outcomes associated with delusions and hallucinations in AD. DESIGN: Three-year observational study. SETTING: Nine memory clinics in Australia. PARTICIPANTS: A total of 445 patients with AD. MEASUREMENTS: Measures of neuropsychiatric symptoms, dementia severity, cognition, function, caregiver burden, and medication use were completed annually for 3 years with additional assessments at 3 months and 6 months in the first year. Mortality data were obtained from state registries approximately 5 years after the study. RESULTS: Of 445 patients, 102 (22.9%) developed only delusions, 39 (8.8%) developed only hallucinations, and 84 (18.9%) developed both symptoms. Delusions and hallucinations were both associated with greater dementia severity, poorer cognition and function, higher levels of other neuropsychiatric symptoms, and greater caregiver burden. The presence of both symptoms was associated with worse outcomes than only one of these symptoms. Delusions, both by themselves and in combination with hallucinations, predicted institutionalization. Antipsychotic medication use predicted mortality. CONCLUSIONS: Delusions and hallucinations independently and in combination are associated with poor clinical outcomes. The findings highlight the challenges managing these patients, particularly given the high levels of caregiver burden associated with psychotic symptoms and the likely mortality arising from antipsychotic medication. PMID- 29174999 TI - Effect of upper body plyometric training on physical performance in healthy individuals: A systematic review. AB - OBJECTIVE: To determine the impact of upper body plyometric training (UBPT) on physical performance parameters such as strength, ball throwing speed, ball throw distance and power in healthy individuals. METHODS: PubMed, Scopus, ResearchGate and ERIC databases were searched up to August 2017. Selection of articles was done if they described the outcomes of an upper body plyometric exercise intervention; included measures of strength, ball throwing speed, ball throw distance, or power; included healthy individuals; used a randomized control trial; and had full text available in English language. The exclusion criteria were unpublished research work and clubbing of UBPT with some other type(s) of training apart from routine sports training. PEDro scale was used to rate the quality of studies eligible for this review. RESULTS: Initially 264 records were identified and out of them only 11 articles met the eligibility criteria and were selected (PEDro score = 4 to 6). Though large to very small effects observed in improving ball throwing velocity, ball throwing distance, power and strength of upper limb muscles after UBPT, the results should be implemented with caution. CONCLUSION: Inconclusive results obtained preclude any strong conclusion regarding the efficacy of UBPT on physical performance in healthy individuals. PMID- 29175001 TI - Contribution of the swine model in the study of human sexually transmitted infections. AB - The pig has garnered more and more interest as a model animal to study various conditions in humans. The growing success of the pig as an experimental animal model is explained by its similarities with humans in terms of anatomy, genetics, immunology, and physiology, by their manageable behavior and size, and by the general public acceptance of using pigs for experimental purposes. In addition, the immunological toolbox of pigs has grown substantially in the last decade. This development led to a boost in the use of pigs as a preclinical model for various human infections including sexually transmitted diseases (STIs) like Chlamydia trachomatis. In the current review, we discuss the use of animal models for biomedical research on the major human STIs. We summarize results obtained in the most common animal models and focus on the contributions of the pig model towards the understanding of pathogenesis and the host immune response. In addition, we present the main features of the porcine model that are particularly relevant for the study of pathogens affecting human female and male genital tracts. We also inform on the technological advancements in the porcine toolbox to facilitate new discoveries in this biologically important animal model. There is a continued need for improvements in animal modeling for biomedical research inclusive STI research. With all its advantages and the highly improved toolbox, the porcine model can play a crucial role in STI research and open the door to new exciting discoveries.

AB - Granulosicoccus, the only genus of the family Granulosicoccaceae, occupies a distinct phylogenetic position within the order Chromatiales of the Gammaproteobacteria. The genus has been found in various marine regions, especially associated with diverse marine macroalgae. No genomes have been reported for the genus Granulosicoccus thus far, hampering studies on physiology and lifestyles of this genus. Here we report the complete genome sequence of strain IMCC3135T, the type strain of Granulosicoccus antarcticus isolated from Antarctic coastal seawater. The genome was 7.78Mbp long and harbored many genes involved in sulfur metabolism. In particular, a gene for dimethylsulfoniopropionate (DMSP) demethylase was found in the genome, rendering strain IMCC3135T one of the few marine gammaproteobacteria equipped with the potential for DMSP demethylation. PMID- 29175004 TI - Editorial. PMID- 29175003 TI - Transcranial direct current stimulation (tDCS) prevents chronic stress-induced hyperalgesia in rats. AB - BACKGROUND: Chronic stress (CS) is associated with a decrease in pain threshold caused by the changes in neural pain circuits. It can be associated to glucocorticoid imbalance with alterations in neural circuitry. Inhibition of stress-induced pain-related neural changes by using techniques that safely induce neuroplasticity such as transcranial direct current stimulation (tDCS) may prevent hyperalgesia triggered by CS. OBJECTIVE: This study aimed to verify the effect of tDCS performed prior to CS exposure on nociceptive response. METHODS: Thirty-two rats were distributed in the following groups: control; stress; sham tDCS + stress; and tDCS + stress. Bicephalic active tDCS was performed for 8 consecutive days before the CS exposure. The pain threshold was evaluated using a hot plate and tail flick latency (TFL) tests. RESULTS: The tDCS exposure increased the pain threshold on stressed rats. CONCLUSION: The data obtained indicate that the treatment with bicephalic active tDCS before chronic stress exposure prevents stress-induced hyperalgesia. PMID- 29175005 TI - Physician perceptions of integrating advanced practice pharmacists into practice. AB - OBJECTIVES: Barriers have prevented full integration of advanced practice pharmacists (APPs) into collaborative practice in some areas despite evidence describing their value. APPs in North Carolina can be recognized as Clinical Pharmacist Practitioners (CPPs) under a collaborative practice agreement and provide comprehensive medication management under physician supervision. This study describes the perceptions of physicians regarding the barriers and benefits of integrating CPPs into interprofessional teams and compares physician and CPP perceptions. METHODS: This prospective descriptive study surveyed CPP supervising physicians in North Carolina. The questionnaire consisted of 17 multiple-choice and free-response questions. Questions included demographics, perceived benefits and challenges of incorporating CPPs into health care teams, and services provided by CPPs. Findings were compared with previously published data that assessed CPP perceptions about the same topics to gain insight into common perspectives of team members. RESULTS: Fifty-six physicians (23.1%) responded, identifying enhanced clinical outcomes (87.5%), access to drug knowledge (58.9%), and creation of a multidisciplinary model for learners (57.1%) as the top benefits of working with CPPs. Primary barriers included limited reimbursement (60.7%) and billing difficulties (51.8%). More CPPs acknowledged provider acceptance as a barrier (25.9% vs. 3.6%; P = 0.001). Twelve physicians (21.4%) and no CPPs identified space as a barrier. CONCLUSION: Physicians identified enhanced clinical outcomes, access to drug knowledge, and creation of a multidisciplinary model for learners as the top benefits of incorporating CPPs into teams, and billing difficulties and limited reimbursement were the primary barriers. These findings were similar to the perceptions of CPPs, with exceptions being that physicians were more concerned about space limitations and CPPs noted that provider acceptance may be difficult. These findings may provide guidance to providers desiring to establish collaborative practice. PMID- 29175006 TI - Predicted cumulative dose to firefighters and the offsite public from natural and anthropogenic radionuclides in smoke from wildland fires at the Savannah River Site, South Carolina USA. AB - The contaminated ground surface at Savannah River Site (SRS) is a result of the decades of work that has been performed maintaining the country's nuclear stockpile and performing research and development on nuclear materials. The volatilization of radionuclides during wildfire results in airborne particles that are dispersed within the smoke plume and may result in doses to downwind firefighters and the public. To better understand the risk that these smoke plumes present, we have characterized four regions at SRS in terms of their fuel characteristics and radiological contamination on the ground. Combined with general meteorological conditions describing typical and extreme burn conditions, we have simulated potential fires in these regions and predicted the potential radiological dose that could be received by firefighting personnel and the public surrounding the SRS. In all cases, the predicted cumulative dose was a small percent of the US Department of Energy regulatory limit (0.25 mSv). These predictions were conservative and assumed that firefighters would be exposed for the duration of their shift and the public would be exposed for the entire day over the duration of the burn. Realistically, firefighters routinely rotate off the firefront during their shift and the public would likely remain indoors much of the day. However, we show that even under worst-case conditions the regulatory limits are not exceeded. We can infer that the risks associated with wildfires would not be expected to cause cumulative doses above the level of concern to either responding personnel or the offsite public.

AB - This paper examined the relationship between radon risk and lung cancer prevalence using a novel dataset combining spatially-coded survey data with a radon risk map. A logit model was employed to test for significant associations between a high risk of indoor radon and lung cancer prevalence using data on 5590 people aged 50+ from The Irish Longitudinal Study on Ageing (TILDA) and radon risk data from Ireland's Environmental Protection Agency (EPA). The use of data at the individual level allowed a wide range of potentially confounding factors (such as smoking) to be included. Results indicate that those who lived in an area in which 10%-20% of households were above the national reference level (200 Bq/m3) were 2.9-3.1 times more likely to report a lung cancer diagnosis relative to those who lived in areas in which less than 1% of households were above the national reference level. PMID- 29175000 TI - Cyclic nucleotide signaling changes associated with normal aging and age-related diseases of the brain. AB - Deficits in brain function that are associated with aging and age-related diseases benefit very little from currently available therapies, suggesting a better understanding of the underlying molecular mechanisms is needed to develop improved drugs. Here, we review the literature to test the hypothesis that a break down in cyclic nucleotide signaling at the level of synthesis, execution, and/or degradation may contribute to these deficits. A number of findings have been reported in both the human and animal model literature that point to brain region-specific changes in Galphas (a.k.a. Galphas or Gsalpha), adenylyl cyclase, 3',5'-adenosine monophosphate (cAMP) levels, protein kinase A (PKA), cAMP response element binding protein (CREB), exchange protein activated by cAMP (Epac), hyperpolarization-activated cyclic nucleotide-gated ion channels (HCNs), atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), soluble and particulate guanylyl cyclase, 3',5'-guanosine monophosphate (cGMP), protein kinase G (PKG) and phosphodiesterases (PDEs). Among the most reproducible findings are 1) elevated circulating ANP and BNP levels being associated with cognitive dysfunction or dementia independent of cardiovascular effects, 2) reduced basal and/or NMDA-stimulated cGMP levels in brain with aging or Alzheimer's disease (AD), 3) reduced adenylyl cyclase activity in hippocampus and specific cortical regions with aging or AD, 4) reduced expression/activity of PKA in temporal cortex and hippocampus with AD, 5) reduced phosphorylation of CREB in hippocampus with aging or AD, 6) reduced expression/activity of the PDE4 family in brain with aging, 7) reduced expression of PDE10A in the striatum with Huntington's disease (HD) or Parkinson's disease, and 8) beneficial effects of select PDE inhibitors, particularly PDE10 inhibitors in HD models and PDE4 and PDE5 inhibitors in aging and AD models. Although these findings generally point to a reduction in cyclic nucleotide signaling being associated with aging and age related diseases, there are exceptions. In particular, there is evidence for increased cAMP signaling specifically in aged prefrontal cortex, AD cerebral vessels, and PD hippocampus. Thus, if cyclic nucleotide signaling is going to be targeted effectively for therapeutic gain, it will have to be manipulated in a brain region-specific manner.

PMID- 29175009 TI - Treatment with mTOR inhibitors after liver transplantation enables a sustained increase in regulatory T-cells while preserving their suppressive capacity. AB - BACKGROUND: The mammalian targets of rapamycin (mTOR) inhibitors (sirolimus [SRL] and everolimus [EVR]) are used after transplantation for their immunosuppressive activity. Regulatory T-cells (Tregs) play a crucial role in immune tolerance. mTOR inhibitors appear to preserve Tregs, unlike Tacrolimus (Tac). AIM: The aim of this study was to evaluate the number and function of Tregs in liver transplant recipients before and after conversion from Tac to mTOR inhibitors. METHODS: Fifteen patients with stable graft function where converted to SRL (n=5) or EVR (n=10). Tregs (CD4+ CD25+ FoxP3+ CD127low) number and activity were analysed prospectively in blood cells using flow cytometry, and functional assay. RESULTS: Patients of both groups displayed a sustained rise in Treg levels after introduction of mTOR inhibitors (Treg levels at 3 months: 6.45+/-0.38% of CD4 T cells, vs. baseline level of 3.61+/-0.37%, P<0.001; mean fold increase 2.04+/ 0.73). In SRL group, 3-month Treg levels were 6.01+/-0.53 vs. 3.79+/-0.39; P=0.037, while in EVR group they were 6.63+/-0.67 vs. 3.54+/-0.51; P=0.001. By contrast, no statistical change was observed in an unconverted Tac control group. Tregs also preserved their functional ability to suppress activated T-cells. CONCLUSION: These results suggest that mTOR inhibitors induce a significant increase in Tregs while maintaining suppressive activity after LT. PMID- 29175011 TI - Effects of moroxydine hydrochloride and ribavirin on the cellular growth and immune responses by inhibition of GCRV proliferation. AB - Moroxydine hydrochloride (Mor) and ribavirin (Rib) are known for their multi antiviral activities against DNA and RNA viruses but little information is available about the pharmacological impact in aquaculture. The present study was undertaken to investigate the response of host cells to antiviral compounds during the anti-GCRV treatment. The scanning electron microscope results showed that Ctenopharyngodon idella kidney (CIK) cells have a higher death rate at 72h post virus infection. At the concentration of 40MUgmL-1, Mor and Rib had a significant protective effect on virus-infected cells. Moreover, the gene expressions of vp5, vp6 and NS66 were significantly inhibited by treatment with Mor or Rib, especially gene expression of the vp5. For the immunoregulatory action, no distinct induction of the expression of immune genes was observed after the addition of Mor and Rib to the virus-free cells. However, the compounds significantly decreased the virus-induced gene overexpression of Myd88, Mx1, IL 1beta, IL-8, I-IFN and TNFalpha in CIK cells. Moreover, Mor and Rib significantly inhibited the immune genes upregulation which was induced by GCRV in kidney, liver, muscle and gill of grass carp, despite greater partial gene expressions were detected than the virus-free control group. Besides, Mor and Rib blocked cell cycle changes, cytopathic effects, cellular death and virus proliferation in CIK cells thereby maintaining normal morphological structure. Overall, Mor and Rib as antiviral compounds are effective for the control of GCRV replication and the indirectly regulation of cellular immune response. PMID- 29175010 TI - Regulation of B cell fate, survival, and function by mitochondria and autophagy. AB - B cells are responsible for protective antibody production after differentiation into antibody-secreting cells during humoral immune responses. From early B cell development in the bone marrow, to their maturation in the periphery, activation in the germinal center, and differentiation into plasma cells or memory B cells, B cells display ever-changing functions and properties. Autophagy and mitochondria play important roles in B cell development, activation, and differentiation to accommodate the phenotypic and environmental changes encountered over the lifetime of the cell. Among their many functions, mitochondria and autophagy generate energy, mediate cell survival, and produce/eliminate reactive oxygen species that can serve as signal molecules to regulate differentiation. As B cells mature and differentiate into plasma or memory cells, both autophagic and mitochondrial functions undergo significant changes. In this review, we aim to provide an overview of the role of the autophagosome and mitochondria in regulating B cell fate, survival, and function. Moreover, we will discuss the interplay between these two highly metabolic organelles during B cell development, maturation, and differentiation. PMID- 29175012 TI - Osteogenic differentiation of equine adipose tissue derived mesenchymal stem cells using CaCl2. AB - Adipose tissue derived mesenchymal stem cells (ASCs) may be used to cure bone defects after osteogenic differentiation. In this study we tried to optimize osteogenic differentiation for equine ASCs using various concentrations of CaCl2 in comparison to the standard osteogenic protocol. ASCs were isolated from subcutaneous adipose tissue from mixed breed horses. The osteogenic induction protocols were (1) the standard osteogenic medium (OM) composed of dexamethasone, ascorbic acid and beta-glycerol phosphate; (2) CaCl2 based protocol composed of 3, 5 and 7.5mM CaCl2. Differentiation and proliferation were evaluated at 7, 10, 14 and 21days post-differentiation induction using the alizarin red staining (ARS) detecting matrix calcification. Semi-quantification of cell protein content, ARS and alkaline phosphatase activity (ALP) were performed using an ELISA reader. Quantification of the transcription level for the common osteogenic markers alkaline phosphatase (ALP) and Osteopontin (OP) was performed using RT qPCR. In the presence of CaCl2, a concentration dependent effect on the osteogenic differentiation capacity was evident by the ARS evaluation and OP gene expression. We provide evidence that 5 and 7mM CaCl2 enhance the osteogenic differentiation compared to the OM protocol. Although, there was a clear commitment of ASCs to the osteogenic fate in the presence of 5 and 7mM CaCl2, cell proliferation was increased compared to OM. We report that an optimized CaCl2 protocol reliably influences ASCs osteogenesis while conserving the proliferation capacity. Thus, using these protocols provide a platform for using ASCs as a cell source in bone tissue engineering. PMID- 29175013 TI - The PB2-K627E mutation attenuates H3N2 swine influenza virus in cultured cells and in mice. AB - PB2-627K is an important amino acid that determines the virulence of some influenza A viruses. However, it has not been experimentally investigated in the H3N2 swine influenza virus. To explore the potential role of PB2-K627E substitution in H3N2 swine influenza virus, the growth properties and pathogenicity between H3N2 swine influenza virus and its PB2-K627E mutant were compared. For the first time, our results showed that PB2-K627E mutation attenuates H3N2 swine influenza virus in mammalian cells and in mice, suggesting that PB2-627K is required for viral replication and pathogenicity of H3N2 swine influenza virus. PMID- 29175014 TI - Influence of sedation on onset and quality of euthanasia in sheep. AB - The purpose of this study was to determine if dexmedetomidine administered IV prior to euthanasia in sheep affected the speed or quality of euthanasia. Twenty clinically healthy Dorset-cross adult ewes between 1 and 3years of age were enrolled in a randomized blinded experimental trial. The subjects were randomly assigned to receive dexmedetomidine 5MUg/kg IV or an equivalent volume of saline. Five minutes later, euthanasia was accomplished with a pentobarbital/phenytoin overdose given IV. The time to apnea, asystole, cessation of audible heartbeat, and absence of corneal reflex were recorded by two blinded investigators. If any muscle spasms, contractions, vocalization, and/or dysrhythmias were noted, the time was recorded and type of ECG abnormality was described. An overall score of the euthanasia event was assigned using a numeric rating scale (NRS) after the animal was declared dead. The time to loss of corneal reflex was significantly longer in sheep given dexmedetomidine compared with those who received saline (P=0.03). Although vocalization was observed only in some animals premedicated with dexmedetomidine, no significance was found for this event and no other significant differences between groups were noted. Dexmedetomidine at 5MUg/kg IV 5min prior to injection of pentobarbital/phenytoin for euthanasia did not substantially affect the progress of euthanasia. Dexmedetomidine may be given to sedate sheep prior to euthanasia without concern for it adversely affecting the progress of euthanasia, however vocalization may occur.

PMID- 29175017 TI - Inhibitory effects of (+)-spectaline and iso-6-spectaline from Senna spectabilis on the growth and ultrastructure of human-infective species Trypanosoma brucei rhodesiense bloodstream form. AB - In our ongoing work searching for new trypanocidal lead compounds from Malaysian plants, two known piperidine alkaloids (+)-spectaline (1) and iso-6-spectaline (2) were isolated from the leaves of Senna spectabilis (sin. Cassia spectabilis). Analysis of the 1H and 13C NMR spectra showed that 1 and 2 presented analytical and spectroscopic data in full agreement with those published in the literature. All compounds were screened in vitro against Trypanosoma brucei rhodesiense in comparison to the standard drug pentamidine. Compound 1 and 2 inhibited growth of T. b. rhodesiense with an IC50 value of 0.41 +/- 0.01 MUM and 0.71 +/- 0.01 MUM, without toxic effect on L6 cells with associated a selectivity index of 134.92 and 123.74, respectively. These data show that piperidine alkaloids constitute a class of natural products that feature a broad spectrum of biological activities, and are potential templates for the development of new trypanocidal drugs. To our knowledge, the compounds are being reported for the first time to have inhibitory effects on T. b. rhodesiense. The ultrastructural alterations in the trypanosome induced by 1 and 2, leading to programmed cell death were characterized using electron microscopy. These alterations include wrinkling of the trypanosome surface, formation of autophagic vacuoles, disorganization of kinetoplast, and swelling of the mitochondria. These findings evidence a possible autophagic cell death. PMID- 29175018 TI - Understanding serine proteases implications on Leishmania spp lifecycle. AB - Serine proteases have significant functions over a broad range of relevant biological processes to the Leishmania spp lifecycle. Data gathered here present an update on the Leishmania spp serine proteases and the status of these enzymes as part of the parasite degradome. The serine protease genes (n = 26 to 28) in Leishmania spp, which encode proteins with a wide range of molecular masses (35 kDa-115 kDa), are described along with their degrees of chromosomal and allelic synteny. Amid 17 putative Leishmania spp serine proteases, only ~18% were experimentally demonstrated, as: signal peptidases that remove the signal peptide from secretory pre-proteins, maturases of other proteins and with metacaspase like activity. These enzymes include those of clans SB, SC and SF. Classical inhibitors of serine proteases are used as tools for the characterization and investigation of Leishmania spp. Endogenous serine protease inhibitors, which are ecotin-like, can act modulating host actions. However, crude or synthetic based natural serine protease inhibitors, such as potato tuber extract, Stichodactyla helianthus protease inhibitor I, fukugetin and epoxy-alpha-lapachone act on parasitic serine proteases and are promising leishmanicidal agents. The functional interrelationship between serine proteases and other Leishmania spp proteins demonstrate essential functions of these enzymes in parasite physiology and therefore their value as targets for leishmaniasis treatment. PMID- 29175019 TI - Long-term outcome and quality of life after initial and repeat resection of colorectal liver metastasis: A retrospective analysis. AB - BACKGROUND: Repeat hepatectomy is a widely accepted treatment for patients with recurrent colorectal liver metastasis (CRLM). The aim of this study was to compare initial and repeat hepatic resection concerning overall survival, prognostic factors and postoperative quality of life. METHODS: Data on patients who underwent initial or repeat hepatic resection for CRLM between 2010 and 2016 were prospectively collected and retrospectively evaluated. Follow-up data, EORTC QLQ-C30 and QLQ-LMC21 questionnaire results for quality of life (QoL) evaluation were analyzed. RESULTS: 160 patients at a median age of 62.8 +/- 11.8 years were analyzed. 122 were initially resected and 38 underwent a repeat hepatic resection. Disease-free survival (DSF) was superior in the initial resection group (p < 0.001), while there was no difference in overall survival (OS) (p = 0.288). BMI >30 (p = 0.012), extrahepatic tumor manifestation (p = 0.037), >1 CRLM manifestation (p = 0.009), and perioperative chemotherapy (p = 0.006) in the initial resection group and primary left colon tumor (p = 0.001) in the repeat resection group were identified as prognostic factors in multivariate Cox regression analysis. EORTC QLQ-LMC-21 module symptom score displayed an increased occurrence of a dry mouth in the initial hepatectomy group (p = 0.003). EORTC QLQ C30 general functioning and symptom scores showed no difference. CONCLUSION: Repeat hepatic resection for CRLM is as effective as primary surgical treatment in terms of OS and QoL. Patients should be selected carefully concerning prognostic factors as DFS is decreased after repeat hepatic resection. PMID- 29175020 TI - Sentinel lymph node biopsy validation for large tumors. AB - BACKGROUND: Sentinel lymph node biopsy (SLNB) remains under discussion for large size tumors. The aim of this work has been to study the false negative rate (FNR) of SLNB for large tumors and predictive factors of false negative (FN). MATERIALS AND METHODS: A study of a multicentric cohort, involved patients presenting N0 breast cancer with a SLNB eventually completed by complementary axillary lymph node dissection (cALND). The main criteria were the FNR and the predictive factors of FN. RESULTS: 12.415 patients were included: 748 with tumors >=30 mm, 1101 with tumors >20 and < 30 mm and 10.566 with tumors <=20 mm, with a cALND respectively for 501 patients (67%), 523 (62.1%) and 2775 (26.3%). The FNR were respectively: 3.05% (IC95%: 1.3-4.8) for tumors >=30 mm*, 3.5% (1.8-5.2) for tumors >20 and < 30 mm*, 1.8% (1-2.4) for tumors <=20 mm (p < 0.05) (*Not significant). At multivariate analysis, SN number harvested <=2 (OR:2.0, p = 0.023) and tumor size >20 and < 30 mm (OR:2.07, p = 0.017) were significant predictive factors of FN, without significant value for tumor size >=30 mm (OR:1.83, p = 0.073). CONCLUSION: The FNR of SLNB was not higher amongst large size tumors compared to tumors of a smaller size. These results support the validation of SNLB for tumors up to 50 mm. PMID- 29175022 TI - Biology and treatment of myeloma related bone disease. AB - Myeloma bone disease (MBD) is the most common complication of multiple myeloma (MM), resulting in skeleton-related events (SREs) such as severe bone pain, pathologic fractures, vertebral collapse, hypercalcemia, and spinal cord compression that cause significant morbidity and mortality. It is due to an increased activity of osteoclasts coupled to the suppressed bone formation by osteoblasts. Novel molecules and pathways that are implicated in osteoclast activation and osteoblast inhibition have recently been described, including the receptor activator of nuclear factor-kB ligand/osteoprotegerin pathway, activin-A and the wingless-type signaling inhibitors, dickkopf-1 (DKK-1) and sclerostin. These molecules interfere with tumor growth and survival, providing possible targets for the development of novel drugs for the management of lytic disease in myeloma but also for the treatment of MM itself. Currently, bisphosphonates are the mainstay of the treatment of myeloma bone disease although several novel agents such as denosumab and sotatercept appear promising. This review focuses on recent advances in MBD pathophysiology and treatment, in addition to the established therapeutic guidelines. PMID- 29175023 TI - Reliability of measurements for sub-painful and painful perception on artificial electrical stimulations. AB - Artificial electrical stimulation is a common type of stimulus to induce sub painful and painful sensation in clinical or neuroscience experiments. The Numerical Rating Scale (NRS) is often used to evaluate subjective perception due to external stimulations. Yet the relationship between the intensity levels of electrical stimulations and self-perception has seldom been examined. The aim of the study was to obtain evidence on the reliability and accuracy of sub-painful and painful perceptions of healthy participants using the NRS under different levels of electrical stimulus. A total of 72 pain-free healthy volunteers (female=44) were recruited. In the first experiment, each participant was given different levels of a non-nociceptive or nociceptive electrical stimulus and then asked to give a perception rating based on an 11-point NRS. In the second experiment, each participant was asked to memorize 5 levels of sub-nociceptive or nociceptive stimuli and to recognize the level of stimulus given each time. For the NRS rating task, intraclass coefficients (ICCs) reached satisfactory level for sub-nociceptive (0.85=0.5mg/L. Sequencing of blaOXA-48-like genes from the S. xiamenensis isolates showed that two strains harboured blaOXA-181, one strain harboured blaOXA-199 and one strain exhibited a new variant of the blaOXA-48-like gene, named blaOXA-538. This new variant shared 98% nucleotide identity with blaOXA-162, with three amino acid changes (G201A, A213G and I219F). Conjugation assays with Escherichia coli J53 recipient were performed but no transconjugants were obtained. Analysis of the genome of AS58 Touati strain confirmed the chromosomal location of the blaOXA-538 gene. CONCLUSION: This study showed that environmental water holds a diversity of S. xiamenensis strains harbouring blaOXA-48-like genes and may play an important role in the dissemination and spread of these genes from the environment to humans.

PMID- 29175036 TI - Evaluation of postoperative patient satisfaction after covering the nasal dorsum with upper lateral cartilage: "upper lateral closing". AB - INTRODUCTION: Following nasal hump removal during septorhinoplasty, the middle vault should be reconstructed to avoid functional and esthetic problems. Middle vault reconstruction, however, may result in widening of the middle vault and may need a camouflage graft to cover dorsal irregularities. OBJECTIVE: To present the results of reconstructing the middle vault with a technique that covers the nasal dorsum with upper lateral cartilage, from the viewpoint of patient satisfaction. METHODS: Retrospective study of patients who underwent septorhinoplasty that included nasal dorsum closure with upper lateral cartilage from December 1, 2014 to January 31, 2016. Those with postoperative follow-up of less than 3 months were excluded. The final study group included 39 patients. The same surgeon performed all septorhinoplasties. The dorsum was closed using an "upper lateral closing" technique that approximated upper lateral cartilages to each other over the septum. Postoperative patient satisfaction was determined using a visual analog scale and the rhinoplasty outcomes evaluation questionnaire. The questionnaire evaluates patient esthetic and functional satisfaction with the operated nose. High scores indicate improved esthetic results. RESULTS: No dorsal irregularities were seen at postoperative follow-up evaluation of the patients. For esthetic nasal appearance, the median visual analogue scale scores was 86%, and the mean for the questionnaire was 77.03%. CONCLUSION: The natural dome shaped anatomy of the nasal dorsum was achieved by approximating the upper lateral cartilages to each other. Closing the dorsum with this technique also covers any dorsal irregularities and results in a smooth dorsum. Patients expressed satisfaction with the esthetic and functional aspects of the smooth, attractive nasal dorsum. PMID- 29175037 TI - Results from a multicenter registry of heparin-bonded expanded polytetrafluoroethylene graft for above-the-knee femoropopliteal bypass. AB - OBJECTIVE: The aim of the study was to retrospectively analyze early and follow up results of above-the-knee femoropopliteal bypasses (AKb) performed with a bioactive heparin-bonded expanded polytetrafluoroethylene (HB-ePTFE) graft in patients with peripheral arterial obstructive disease in a multicentric retrospective registry involving seven Italian vascular centers. METHODS: During a 14-year period ending in March 2016, an HB-ePTFE graft was used in 1401 interventions performed for peripheral arterial obstructive disease. Comorbidities, risk factors, and follow-up outcomes were collected in a multicenter registry with a dedicated database. A post hoc analysis of the database was performed to identify 364 (25.9%) patients who underwent AKb. Early (intraoperative and <30 days) results were analyzed in terms of death, thrombosis, amputations, reinterventions, and the occurrence of major local and systemic complications. Follow-up results were analyzed by life-table analysis (Kaplan-Meier test) in terms of primary and secondary graft patency, assisted primary patency, limb preservation, and amputation-free survival. The analysis of follow-up results was stopped in December 2016. RESULTS: In 61 (16.7%) patients, AKb was performed after the failure of a previous ipsilateral revascularization. Critical limb ischemia was present in 164 (45%) cases; the remaining patients had life-limiting intermittent claudication. Perioperative mortality occurred in three (0.8%) patients: in the hospital (n = 2) due to acute myocardial infarction and after discharge (n = 1) due to fatal arrhythmia. Early thromboses occurred in six (1.6%) patients; all these patients had primary AKb for critical limb ischemia. The cumulative rate of perioperative amputations was 0.5% (2 cases), whereas the cumulative rate of early reinterventions was 3% (11 cases). Median duration of follow-up was 28 months (range, 1-168 months); the median cumulative follow-up index for survival was 0.75 (range, 0.05-1). Estimated survival at 5 years was 75.3% (standard error [SE], 0.03). Estimated 5-year primary patency was 64% (SE, 0.04); the corresponding figure in terms of assisted primary patency was 65% (SE, 0.035). Secondary patency rate at 5 years was 74.5% (SE, 0.03). The rate of limb preservation at 5 years was 95% (SE, 0.02); the corresponding figure in terms of amputation-free survival was 74% (SE, 0.04). CONCLUSIONS: In an era of endovascular enthusiasm, with conflicting results for the treatment of long or complex lesions of the superficial femoral artery, AKb with the use of HB-ePTFE graft remains an effective option, with low rate of perioperative complications and satisfactory long-term results. PMID- 29175038 TI - Renin-angiotensin system blockade does not attenuate abdominal aortic aneurysm growth, rupture rate, or perioperative mortality after elective repair. AB - OBJECTIVE: The objective of this study was to summarize the literature regarding the effects of renin-angiotensin system blockade (RASB) using angiotensin converting enzyme inhibitors (ACEis) or angiotensin receptor blockers (ARBs) on human abdominal aortic aneurysm (AAA) growth, rupture, and perioperative mortality. METHODS: We conducted a systematic review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Our review protocol was registered at the International Prospective Register of Systematic Reviews (CRD42016054082). We searched the Cochrane Central Register of Controlled Trials database, MEDLINE, and Embase from inception to 2017 for studies examining the effects of ACEi or ARB treatment on AAA growth, rupture, or perioperative mortality. Review, abstraction, and quality assessment were conducted in duplicate, and a third author resolved discrepancies. We assessed study quality using the Cochrane and Newcastle-Ottawa scales. We used random-effects models to calculate pooled mean differences and odds ratios (ORs) with 95% confidence intervals (CIs). Heterogeneity was quantified using the I2 statistic. RESULTS: Our search yielded 525 articles. One randomized and seven observational studies involving 35,448 patients were included. Inter-rater agreement was excellent (kappa = 0.78), and risk of bias was low to moderate. All studies investigated ACEis, three studies investigated ARBs, and two studies included a composite RASB group consisting of ACEi or ARB users. Five studies assessed AAA growth, two assessed rupture rate, and one reported 30-day mortality after elective open repair. There was no difference in AAA growth rate between RASB and control (mean difference, 0.03 mm/y; 95% CI, -0.40 to 0.46; P = .88; I2 = 60%). No protective effect of RASB (OR, 0.92; 95% CI, 0.72, 1.16; P = .47; I2 = 90%) was demonstrated for AAA rupture. Finally, RASB increased 30-day mortality in patients undergoing elective open AAA repair (OR, 5; 95% CI, 1.4, 27) according to a single well adjusted study. CONCLUSIONS: RASB does not appear to affect AAA growth and rupture rate but increases elective perioperative mortality. The small number of heterogeneous, retrospective studies and limited long-term follow-up preclude a definitive dismissal of RASB as pharmacotherapy for AAA. Prospective, long-term data are needed to clarify the effect of RASB on AAA growth, rupture, and perioperative mortality.

AB - PURPOSE: (1) To test whether serum bicarbonate or anion gap can be used to predict elevated lactate or mortality in emergency department (ED) patients with sepsis, and (2) to define thresholds that may predict elevated lactate and mortality. METHODS: Retrospective diagnostic-validation study of adults with sepsis treated in a 60,000-visit Midwestern university ED (2010-2015). In the derivation sample, 8 experts selected thresholds based on objective measures to optimize clinical utility. Test performance was reported using likelihood ratios (LR +/-) in the validation cohort. RESULTS: We included 4159 patients. Anion gap predicted lactate>2 better than bicarbonate [ROC AUC 0.680 vs. 0.609], and anion gap predicted lactate>4 better than lactate>2 [ROC AUC 0.816 vs. 0.680]. In the validation cohort, anion gap >=20mEq/L had LR+ for lactate>2 of 3.670 (2.630 5.122), lactate>4 of 7.019 (5.310-9.278), and mortality of 2.768 (1.922-3.986). Anion gap predicted mortality similar to lactate>2 [LR+ 2.768 vs. LR+ 2.09; LR- 0.823 vs. 0.447]. CONCLUSIONS: Anion gap and serum bicarbonate poorly predict changes in lactate and mortality. In resource-limited settings where lactate is unavailable, anion gap >=20mEq/L may be used to further risk-stratify patients for ongoing sepsis care, but lactate remains a preferred biomarker. PMID- 29175047 TI - Hemorrhagic shock drives glycocalyx, barrier and organ dysfunction early after polytrauma. AB - Polytrauma (PT) is frequently associated with hemorrhagic shock (HS), which increases morbidity and mortality. Although various aspects of HS have been addressed in PT patients, the impact of an additional HS is largely unknown regarding the development of multiple organ dysfunction associated with disturbed glycocalyx and barrier function early after trauma. A prospective, longitudinal, mono-centered, observational study enrolling severely injured patients (Injury Severity Score, ISS=38.1+/-2.6) served for an in-depth analysis of blood (drawn on days 0, 1, 2, 3 and 5) and clinical data (up to 21days) of 30 patients who were then stratified into PT with and without HS. HS significantly enhanced signs of acute organ injury, assessed by increased serum concentrations of novel damage markers. Moreover, indicators of glycocalyx and tight-junction dysfunction were found in PT patients all of which were significantly enhanced in co-presence of HS. These markers revealed multiple significant correlations with specific barrier, fluid-balance, coagulation, inflammation, and clinical-outcome parameters. Strikingly, mucosa fragments, which affected clotting, could be detected in serum after PT/HS. The results point to HS as a main driver for glycocalyx and barrier breakdown and suggest novel tools for the monitoring of organ dysfunction in the early course after PT.

PMID- 29175050 TI - Vacuolar protein sorting 13C is a novel lipid droplet protein that inhibits lipolysis in brown adipocytes. AB - OBJECTIVE: Brown adipose tissue (BAT) thermogenesis depends on the mobilization and oxidation of fatty acids from intracellular lipid droplets (LD) within brown adipocytes (BAs); however, the identity and function of LD proteins that control BAT lipolysis remain incomplete. Proteomic analysis of mouse BAT subcellular fractions identified vacuolar protein sorting 13C (VPS13C) as a novel LD protein. The aim of this work was to investigate the role of VPS13C on BA LDs. METHODS: Biochemical fractionation and high resolution confocal and immuno-transmission electron microscopy (TEM) were used to determine the subcellular distribution of VPS13C in mouse BAT, white adipose tissue, and BA cell culture. Lentivirus delivered shRNA was used to determine the role of VPS13C in regulating lipolysis and gene expression in cultured BA cells. RESULTS: We found that VPS13C is highly expressed in mouse BAT where it is targeted to multilocular LDs in a subspherical subdomain. In inguinal white adipocytes, VPS13C was mainly observed on small LDs and beta3-adrenergic stimulation increased VPS13C in this depot. Silencing of VPS13C in cultured BAs decreased LD size and triglyceride content, increased basal free fatty acid release, augmented the expression of thermogenic genes, and enhanced the lipolytic potency and efficacy of isoproterenol. Mechanistically, we found that BA lipolysis required activation of adipose tissue triglyceride lipase (ATGL) and that loss of VPS13C greatly increased the association of ATGL to LDs. CONCLUSIONS: VPS13C is present on BA LDs where is targeted to a distinct subdomain. VPS13C limits the access of ATGL to LD and loss of VPS13C elevates lipolysis and promotes oxidative gene expression. PMID- 29175051 TI - Fatty acid oxidation is required for active and quiescent brown adipose tissue maintenance and thermogenic programing. AB - OBJECTIVE: To determine the role of fatty acid oxidation on the cellular, molecular, and physiologic response of brown adipose tissue to disparate paradigms of chronic thermogenic stimulation. METHODS: Mice with an adipose specific loss of Carnitine Palmitoyltransferase 2 (Cpt2A-/-), that lack mitochondrial long chain fatty acid beta-oxidation, were subjected to environmental and pharmacologic interventions known to promote thermogenic programming in adipose tissue. RESULTS: Chronic administration of beta3 adrenergic (CL-316243) or thyroid hormone (GC-1) agonists induced a loss of BAT morphology and UCP1 expression in Cpt2A-/- mice. Fatty acid oxidation was also required for the browning of white adipose tissue (WAT) and the induction of UCP1 in WAT. In contrast, chronic cold (15 degrees C) stimulation induced UCP1 and thermogenic programming in both control and Cpt2A-/- adipose tissue albeit to a lesser extent in Cpt2A-/- mice. However, thermoneutral housing also induced the loss of UCP1 and BAT morphology in Cpt2A-/- mice. Therefore, adipose fatty acid oxidation is required for both the acute agonist-induced activation of BAT and the maintenance of quiescent BAT. Consistent with this data, Cpt2A-/- BAT exhibited increased macrophage infiltration, inflammation and fibrosis irrespective of BAT activation. Finally, obese Cpt2A-/- mice housed at thermoneutrality exhibited a loss of interscapular BAT and were refractory to beta3-adrenergic-induced energy expenditure and weight loss. CONCLUSION: Mitochondrial long chain fatty acid beta-oxidation is critical for the maintenance of the brown adipocyte phenotype both during times of activation and quiescence.

AB - BACKGROUND: Antiretroviral therapy (ART) has reduced AIDS-defining cancer (ADC) mortality, but its effect on non-AIDS-defining cancer (NADC) mortality is unclear. To help inform cancer prevention and screening, we evaluated trends in NADC mortality among people with AIDS (PWA) in the ART era. METHODS: This retrospective cohort study analyzed AIDS surveillance data, including causes of death from death certificates, for PWA in San Francisco who died in 1996-2013. Proportional mortality ratios (PMRs), and year, age, race, sex-adjusted standardized mortality ratios (SMRs) were calculated for 1996-1999, 2000-2005, and 2006-2013, corresponding to advances in ART. RESULTS: The study included 5822 deceased PWA of whom 90% were male and 68% were aged 35-54 at time of death. Over time, the PMRs significantly decreased for ADCs (2.6%, 1.4%, 1.2%) and increased for NADCs (4.3%, 7.0%, 12.3%). For all years combined (1996-2013) and compared to the California population, significantly elevated SMRs were observed for these cancers: all NADCs combined (2.1), anal (58.4), Hodgkin lymphoma (10.5), liver (5.2), lung/larynx (3.0), rectal (5.2), and tongue (4.7). Over time, the SMRs for liver cancer (SMR 19.8, 11.2, 5.0) significantly decreased while the SMRs remained significantly elevated over population levels for anal (SMR 123, 48.2, 45.5), liver (SMR 19.8, 11.2, 5.0), and lung/larynx cancer (SMR 5.3, 4.7, 3.6). CONCLUSION: A decline in ADC PMRs and increase in NADC PMRs represent a shift in the cancer burden, likely due to ART use. Moreover, given their elevated SMRs, anal, liver, and lung/larynx cancer remain targets for improved cancer prevention, screening, and treatment. PMID- 29175053 TI - The evolutionary conservation of the bidirectional activity of the NWC gene promoter in jawed vertebrates and the domestication of the RAG transposon. AB - The RAG-1 and RAG-2 genes form a recombinase complex that is indispensable for V(D)J recombination, which generates the diversity of immunoglobulins and T-cell receptors. It is widely accepted that the presence of RAGs in the genomes of jawed vertebrates and other lineages is a result of the horizontal transfer of a mobile genetic element. While a substantial amount of evidence has been gathered that clarifies the nature of the RAG transposon, far less attention has been paid to the genomic site of its integration in various host organisms. In all genomes of the jawed vertebrates that have been studied to date, the RAG genes are located in close proximity to the NWC gene. We have previously shown that the promoter of the murine NWC genes exhibits a bidirectional activity, which may have facilitated the integration and survival of the RAG transposon in the host genome. In this study, we characterise the promoters of the NWC homologues that are present in the representatives of other jawed vertebrates (H. sapiens, X. tropicalis and D. rerio). We show that the features that are characteristic for promoters as the hosts of a successful transposon integration (in terms of the arrangement, bidirectional and constitutive activity and the involvement of the Zfp143 transcription factor in the promoter regulation) are evolutionarily conserved, which indicates that the presence of RAG genes in jawed vertebrates is a direct result of a successful transposon integration into the NWC locus. PMID- 29175054 TI - Phenotypic and functional characterization of porcine bone marrow monocyte subsets. AB - Monocytes comprise several subsets with distinct phenotypes and functional capacities. Based on CD163 expression, two major monocyte subsets can be discriminated in the porcine bone marrow. The CD163+ cells expressed higher levels of SLA-DR, Siglec-1, CD11R1 and CD16 when compared to CD163- monocytes, whereas no remarkable differences were observed in the expression of other markers analyzed. Gene expression analysis showed differential expression of several chemokine receptor and TLR genes. Both subsets phagocytosed microspheres with similar efficiency. However, CD163- cells tended to produce higher levels of ROS in response to PMA, whereas CD163+ cells were more efficient in endocytosing and processing antigens (DQ-OVA). CD163- monocytes produced higher levels of TNF alpha and IL-10 than CD163+ cells when stimulated with LPS or Imiquimod. Both subsets produced similar amounts of IL-8 in response to LPS; however, CD163+ cells produced more IL-8 after Imiquimod stimulation. Whether these subsets represent different developmental stages, and how are they related remain to be investigated. PMID- 29175055 TI - Cortical morphometric changes after spinal cord injury. AB - Neuroimaging studies suggest that spinal cord injury (SCI) may lead to significant anatomical alterations in the human sensorimotor system. In particular, voxel-based morphometry (VBM) of cortical volume has revealed a significant gray and white matter atrophy bilaterally in the primary sensory cortex (S1). By contrast, some structural studies failed to detect changes in gray matter volume (GMV) in the primary motor cortex (M1) following SCI, whereas others have reported a substantial decrease of GMV also in M1. In addition to direct degeneration of the sensorimotor cortex, SCI can also lead to atrophy of the non-sensorimotor cortex, such as anterior cingulate cortex, insular cortex, middle frontal gyrus and supplementary motor area. These findings suggest that SCI can cause remote atrophy of brain gray matter in the salient network. Furthermore, pain-related remodelling may occur in SCI. In fact, structural changes in SCI are also related to the presence and degree of below-level pain. We performed a systematic review of the neuroimaging studies showing morphometric cortical changes and subsequent functional reorganization in humans with SCI. Literature search was conducted using PubMed and Embase. We identified 12 articles matching the inclusion criteria and 195 patients were included in these studies. The wide range of disease duration, rehabilitation training, drug intervention, and different research methodology, especially the identification of region of interest and the statistical approach to correct for multiple comparisons, may have contributed to some inconsistencies between the reviewed studies. Nevertheless, neuroimaging biomarkers can assess the extent of neural damage, elucidate the mechanisms of neural repair, and predict clinical outcome. A better understanding of the structural and functional changes that occur at cortical level following SCI may be useful in tracking potential treatment induced changes and identifying potential therapeutic targets, thus developing evidence-based rehabilitation therapies. PMID- 29175056 TI - Evaluation of cardiac energetics by non-invasive 31P magnetic resonance spectroscopy. AB - Alterations in myocardial energy metabolism have been implicated in the pathophysiology of cardiac diseases such as heart failure and diabetic cardiomyopathy. 31P magnetic resonance spectroscopy (MRS) is a powerful tool to investigate cardiac energetics non-invasively in vivo, by detecting phosphorus (31P)-containing metabolites involved in energy supply and buffering. In this article, we review the historical development of cardiac 31P MRS, the readouts used to assess cardiac energetics from 31P MRS, and how 31P MRS studies have contributed to the understanding of cardiac energy metabolism in heart failure and diabetes. This article is part of a Special issue entitled Cardiac adaptations to obesity, diabetes and insulin resistance, edited by Professors Jan F.C. Glatz, Jason R.B. Dyck and Christine Des Rosiers. PMID- 29175058 TI - Instituting Ultrasound-Guided FNA for Thyroid Nodules into a General Surgery Residency Program: What We Learned. AB - BACKGROUND: Evaluation of a thyroid nodule is a common referral seen by surgeons and frequently requires ultrasound-guided fine needle aspiration (US-guided FNA). While surgical residents may have sufficient exposure to thyroid surgery, many lack exposure to office-based procedures, such as US-guided FNA. General surgery residents should be provided with knowledge and practical skills in the application of diagnostic and interventional neck ultrasound to manage the common workup of a thyroid nodule. METHODS: This study sought to instruct and measure surgical residents' performance in thyroid US-guided FNA and evaluate their views regarding instituting such a formal curriculum. Twelve (n = 12) senior residents completed a written pretest and questionnaire, then watched an instructional video and practiced a simulated thyroid US-guided FNA on our created model. Then residents were evaluated while performing actual thyroid US-guided FNAs on patients in our clinic. Residents then completed the same written exam and questionnaire for objective measure. RESULTS: Eight of the chief residents (62%) felt "not comfortable" with the procedure on the pre-course survey; this was reduced to 0% on the post-course survey. Moderate comfort level increased from 15% to 50% and extreme comfort increased from 0% to 8%. From the 11 residents who completed the pre- and post-test exam, 82% (n = 9) significantly improved their score through the curriculum (pre-test: 40.9 vs. post-test: 61.8; p = 0.05). CONCLUSION: With focused instruction, residents are able to learn ultrasound guided thyroid biopsy with improvement in subjective confidence level and objective measures. Resident feedback was positive and emphasized the importance of such training in surgical residency curriculum. PMID- 29175057 TI - Simvastatin blocks soluble SSAO/VAP-1 release in experimental models of cerebral ischemia: Possible benefits for stroke-induced inflammation control. AB - Beyond cholesterol reduction, statins mediate their beneficial effects on stroke patients through pleiotropic actions. They have shown anti-inflammatory properties by a number of different mechanisms, including the inhibition of NF kappaB transcriptional activity and the consequent increase and release of adhesion molecules. We have studied simvastatin's effects on the vascular enzyme semicarbazide-sensitive amine oxidase/vascular adhesion protein 1 (SSAO/VAP-1), which is involved in stroke-mediated brain injury. SSAO/VAP-1 has leukocyte binding capacity and mediates the expression of other adhesion proteins through signaling molecules generated by its catalytic activity. Our results indicate that soluble SSAO/VAP-1 is released into the bloodstream after an ischemic stimulus, in parallel with an increase in E-selectin and VCAM-1 and correlating with infarct volume. Simvastatin blocks soluble SSAO/VAP-1 release and prevents E selectin and VCAM-1 overexpression as well. Simvastatin also effectively blocks SSAO/VAP-1-mediated leukocyte adhesion, although it is not an enzymatic inhibitor of SSAO in vitro. In addition, simvastatin-induced changes in adhesion molecules are greater in human brain endothelial cell cultures expressing SSAO/VAP-1, compared to those not expressing it, indicating some synergic effect with SSAO/VAP-1. We think that part of the beneficial effect of simvastatin in stroke is mediated by the attenuation of the SSAO/VAP-1-dependent inflammatory response. PMID- 29175059 TI - Relationship between temperament and fatness in 11-year-old children and 17-year old adolescents from Wroclaw, Poland. AB - Childhood obesity is increasing globally, and Poland is no exception. Studies indicate that relationship between obesity and psychological well-being is a complex issue and this needs further research. The objective of the present cross sectional study was to analyze the relationship between some temperament components and fatness among children in two developmental periods, approximately before and after adolescence. Participants included 122 children aged 11 years (57 boys and 65 girls), and 153 adolescents aged 17 years (64 boys and 89 girls) from 6 primary and 4 secondary schools in Wroclaw, Poland. Height, weight, triceps-, subscapular and abdominal skinfold thicknesses were measured. Temperament was assessed by a questionnaire of Buss and Plomin (1984) in two versions: EAS-C for children completed by parents and EAS-D for youth and adults. Physical activity (PAL) was also assessed by a questionnaire. Mean, median and standard deviation (SD) were calculated and Student's t tests were performed to test for significance of differences between groups. Chi squared (chi2) statistic was used to test the significance of differences in frequencies. Analyses of covariance (ANCOVA) were performed to show the effect of the social - psychological factors on fatness. Controlling for socioeconomic status and physical activity level, activity, as a component of temperament had a significant effect on body fatness. The only component of temperament, which significantly influenced level of fatness in girls, was emotionality. These relationships differed according to sex and the two age groups concerned. PMID- 29175060 TI - Evaluation of the contribution of D9S1120 to anthropological studies in Native American populations. AB - The D9S1120 locus exhibits a population-specific allele of 9 repeats (9RA) in all Native American and two Siberian populations currently studied, but it is absent in other worldwide populations. Although this feature has been used in anthropological genetic studies, its impact on the evaluation of the structure and genetic relations among Native American populations has been scarcely assessed. Consequently, the aim of this study was to evaluate the anthropological impact of D9S1120 when it was added to STR population datasets in Mexican Native American groups. We analyzed D9S1120 by PCR and capillary electrophoresis (CE) in 1117 unrelated individuals from 13 native groups from the north and west of Mexico. Additional worldwide populations previously studied with D9S1120 and/or 15 autosomal STRs (Identifier kit) were included for interpopulation analyses. We report statistical results of forensic importance for D9S1120. On average, the modal alleles were the Native American-specific allele 9RA (0.3254) and 16 (0.3362). Genetic distances between Native American and worldwide populations were estimated. When D9S1120 was included in the 15 STR population dataset, we observed improvements for admixture estimation in Mestizo populations and for representing congruent genetic relationships in dendrograms. Analysis of molecular variance (AMOVA) based on D9S1120 confirms that most of the genetic variability in the Mexican population is attributable to their Native American backgrounds, and allows the detection of significant intercontinental differentiation attributed to the exclusive presence of 9RA in America. Our findings demonstrate the contribution of D9S1120 to a better understanding of the genetic relationships and structure among Mexican Native groups. PMID- 29175061 TI - Sex-specific reliability and multidimensional stability of responses to tests assessing neuromuscular function. AB - The objective of this study was to estimate sex-specific effects in the test retest cross-reliability of peripheral and central changes in nonlinear and linear measures of a surface electromyography signal during a brief (5 second) and sustained (2minute) isometric maximal voluntary contraction, combined with superimposed electrical stimulation involving the ankle plantar flexors over five identical trials. In this study, we repeated the testing protocol used in our previous study of 10 women (age 20.9, SD=0.3 years) (Bernecke et al., 2015) in a group of 10 men (age 21.2, SD=0.4 years). Despite the central (sex effect; p<0.05, etap2>0.71, SP>70%) and peripheral fatigability (sex effect; p<0.01, etap2>0.8, SP>90%) during sustained isometric maximal voluntary contraction, and lower reliability for central activation ratio during brief (intraclass correlation coefficient [ICC]=0.95 for men and ICC=0.82 for women) and sustained maximal voluntary contraction (ICC>0.82 for men and ICC>0.66 for women) over ankle plantar flexors expressed in women more than in men, all the ICCs of all indices measured by tests assessing neuromuscular function across the five identical test-retest trials were found as meaningful (correlation significance of p<0.05 was reached) and no significant differences were found between trials for any of the measured variables. In conclusion, the present study demonstrated greater central and peripheral fatigue for female participants following sustained (2minute) isometric maximal voluntary contraction of the plantar flexor muscles for all repeated trials and indicated an acceptable agreement between measurements of the characteristic variables made using the three different devices (dynamometry, electrical stimulation, and surface electromyography) over time for both sexes. PMID- 29175062 TI - Organ/body-on-a-chip based on microfluidic technology for drug discovery. AB - Although animal experiments are indispensable for preclinical screening in the drug discovery process, various issues such as ethical considerations and species differences remain. To solve these issues, cell-based assays using human-derived cells have been actively pursued. However, it remains difficult to accurately predict drug efficacy, toxicity, and organs interactions, because cultivated cells often do not retain their original organ functions and morphologies in conventional in vitro cell culture systems. In the MUTAS research field, which is a part of biochemical engineering, the technologies of organ-on-a-chip, based on microfluidic devices built using microfabrication, have been widely studied recently as a novel in vitro organ model. Since it is possible to physically and chemically mimic the in vitro environment by using microfluidic device technology, maintenance of cellular function and morphology, and replication of organ interactions can be realized using organ-on-a-chip devices. So far, functions of various organs and tissues, such as the lung, liver, kidney, and gut have been reproduced as in vitro models. Furthermore, a body-on-a-chip, integrating multi organ functions on a microfluidic device, has also been proposed for prediction of organ interactions. We herein provide a background of microfluidic systems, organ-on-a-chip, Body-on-a-chip technologies, and their challenges in the future. PMID- 29175063 TI - Status of nucleolar channel systems in uterine secretions accurately reflects their prevalence-a marker for the window of implantation-in simultaneously obtained endometrial biopsies. AB - OBJECTIVE: To assess whether nucleolar channel systems (NCSs) can be detected in exfoliated endometrial epithelial cells (EECs) of uterine secretions and whether such noninvasively determined NCS status is associated with significant NCS prevalence in simultaneously obtained endometrial biopsies. DESIGN: Prospective study (December 2015-February 2017). SETTING: University-affiliated and private fertility clinics. PATIENT(S): Luteal-phase patients of reproductive age requiring endometrial biopsy for medical indications. INTERVENTION(S): Uterine secretion aspiration before endometrial biopsy. Cells in uterine secretions were spun onto slides and fixed. NCSs were identified and quantified in cells and paraffin-embedded tissue sections by indirect immunofluorescence. MAIN OUTCOME MEASURE(S): Comparison of NCS status of uterine secretions with NCS prevalence in biopsies. Based on NCS detection, uterine secretions were assigned a status of NCS-positive (n = 15) or NCS-negative (n = 7). NCS prevalence in biopsies was expressed as a percentage of NCSs per EECs. RESULT(S): NCSs can be detected in exfoliated EECs of uterine secretions. Median NCS prevalence in endometrial biopsies from patients with NCS-positive secretions was 41.9% (interquartile range [IQR], 21.1-53.9) versus 2.0% (IQR, 0-6.9) when secretions were NCS negative. The NCS status of secretions identified a significant difference in NCS prevalence of simultaneously obtained biopsies. CONCLUSION(S): NCS status of secretions accurately reflects NCS prevalence of biopsies, a marker for the implantation window. As secretion aspiration is compatible with same-day ET, our study provides proof of principle for a minimally invasive approach to determine endometrial receptivity for timing frozen ET. PMID- 29175065 TI - Effect of the initiation of progesterone supplementation in in vitro fertilization-embryo transfer outcomes: a prospective randomized controlled trial. AB - OBJECTIVE: To analyze the influence of the start point of luteal support on clinical pregnancy rate, implantation rate, and live birth rate of in vitro fertilization and embryo transfer (IVF-ET) cycles. DESIGN: Single-center prospective randomized controlled trial. SETTING: University-affiliated IVF unit. PATIENT(S): Women <=35 years of age with day 3 FSH levels <15 mIU/mL, who were undergoing their first IVF-ET cycles and received ovarian stimulation with the use of a GnRH agonist long protocol. INTERVENTION(S): The patients were randomized on the day of hCG trigger to receive luteal phase support either 1 day after oocyte retrieval (group A) or on the day of oocyte retrieval (group B). MAIN OUTCOME MEASURE(S): Clinical pregnancy rate, implantation rate, miscarriage rate in the first trimester of pregnancy, and live birth rate per embryo transfer cycle. RESULT(S): Two hundred thirty-three patients were enrolled in this study: 117 were assigned to group A and 116 to group B. The clinical pregnancy rate (group A vs. group B: 55.3% vs. 51.5%), implantation rate (38.4% vs. 38.0%), and miscarriage rate (7.7% vs. 7.5%) were similar between the two groups. The live birth rate also did not significantly differ between the two groups (45.7% vs. 46.6%). CONCLUSION(S): Our study indicated that the initiation of progesterone supplementation 1 day after oocyte retrieval did not decrease the clinical pregnancy rate, implantation rate, or live birth rate in women undergoing IVF-ET cycles with the use of the GnRH agonist long protocol. CLINICAL TRIAL REGISTRATION NUMBER: ChiCTR-IPR-14005293. PMID- 29175064 TI - Difference between mean gestational sac diameter and crown-rump length as a marker of first-trimester pregnancy loss after in vitro fertilization. AB - OBJECTIVE: To investigate whether the difference between mean gestational sac diameter and crown-rump length (mGSD - CRL) is associated with first-trimester pregnancy loss or adverse pregnancy outcomes after in vitro fertilization (IVF) and to determine if mGSD - CRL is a better predictor of pregnancy loss than either measurement alone. DESIGN: Retrospective cohort study. SETTING: University hospital. PATIENT(S): A total of 1,243 IVF cycles with fresh or cryopreserved autologous embryo transfers resulting in singleton gestations performed at the University of Iowa Hospitals and Clinics from January 2005 through December 2014. Cycles included ultrasound measurements of mGSD and CRL at 45-56 days' gestation. INTERVENTION(S): Mean gestational sac diameter to crown-rump length difference. MAIN OUTCOME MEASURE(S): Primary outcomes were first-trimester pregnancy loss and gestational age at delivery. Secondary outcomes were infant birth weight and pregnancy complications. RESULT(S): First-trimester pregnancy loss rates were significantly higher in pregnancies with mGSD - CRL <5 mm (43.7%) compared with 5 9.99 mm (15.8%), 10-14.99 mm (9.9%), and >=15 mm (7.1%). No correlations were found with infant birth weight, gestational age at delivery, or other pregnancy complications. mGSD - CRL was not a better predictor of pregnancy loss than mGSD or CRL alone. CONCLUSION(S): There is a strong inverse relationship between mGSD CRL and first-trimester pregnancy loss in IVF patients, although the incidence of pregnancy loss with a mGSD - CRL <5 mm was significantly lower than previously reported. Small mGSD - CRL was not associated with an increased risk of complications in pregnancies that continued beyond 20 weeks. The association between mGSD, CRL, and miscarriage is complex. PMID- 29175066 TI - Randomized controlled trial comparing embryo culture in two incubator systems: G185 K-System versus EmbryoScope. AB - OBJECTIVE: To study whether the closed culture system, as compared with a benchtop incubator with similar culture conditions, has a positive impact on intracytoplasmic sperm injection (ICSI) outcomes. DESIGN: Randomized controlled trial. SETTING: University hospital. PATIENT(S): A total of 386 patients undergoing ICSI cycles with at least six mature oocytes were randomized. INTERVENTION(S): Of these patients, 195 were assigned to the group with culture in a time-lapse imaging (TLI) system (EmbryoScope) and 191 to the group with culture in the G185 K-System (G185). MAIN OUTCOME MEASURE(S): Rate of implantation (primary endpoint) and embryo morphology grade. RESULT(S): No significant differences were found in the implantation rates. The proportion of high-grade embryos on day 2 was significantly higher in the TLI group compared with the G185 group (40.4% vs. 35.2%). The impact of the incubator on embryo morphology remained significant in multivariate analysis, which took into account the woman's age, the rank of attempt, and the smoking status (TLI vs. G185: odds ratio = 1.27; 95% confidence interval, [1.04-1.55]). No difference was found in the mean number of frozen embryos, even though the total proportion of frozen embryos was significantly higher in the TLI group than in the G185 group (29.5% vs. 24.8%). CONCLUSION(S): No difference in implantation rate was found between the two incubators for fresh cycles. It remains to be determined whether the observed differences in embryo morphology and the total number of embryos cryopreserved would translate into higher cumulative outcomes with subsequent frozen embryo transfers. CLINICAL TRIAL REGISTRATION NO: NCT02722252. PMID- 29175067 TI - Quality of life and psychosocial and physical well-being among 1,023 women during their first assisted reproductive technology treatment: secondary outcome to a randomized controlled trial comparing gonadotropin-releasing hormone (GnRH) antagonist and GnRH agonist protocols. AB - OBJECTIVE: To compare self-reported quality of life, psychosocial well-being, and physical well-being during assisted reproductive technology (ART) treatment in 1,023 women allocated to either a short GnRH antagonist or long GnRH agonist protocol. DESIGN: Secondary outcome of a prospective phase 4, open-label, randomized controlled trial. Four times during treatment a questionnaire on self reported physical well-being was completed. Further, a questionnaire on self reported quality of life and psychosocial well-being was completed at the day of hCG testing. SETTING: Fertility clinics at university hospitals. PATIENT(S): Women referred for their first ART treatment were randomized in a 1:1 ratio and started standardized ART protocols. INTERVENTION(S): Gonadotropin-releasing hormone analogue; 528 women allocated to a short GnRH antagonist protocol and 495 women allocated to a long GnRH agonist protocol. MAIN OUTCOME MEASURE(S): Self reported quality of life, psychosocial well-being, and physical well-being based on questionnaires developed for women receiving ART treatment. RESULT(S): Baseline characteristics were similar, and response rates were 79.4% and 74.3% in the GnRH antagonist and GnRH agonist groups, respectively. Self-reported quality of life during ART treatment was rated similar and slightly below normal in both groups. However, women in the GnRH antagonist group felt less emotional (adjusted odds ratio [AOR] 0.69), less limited in their everyday life (AOR 0.74), experienced less unexpected crying (AOR 0.71), and rated quality of sleep better (AOR 1.55). Further, women receiving GnRH agonist treatment felt worse physically. CONCLUSION(S): Women in a short GnRH antagonist protocol rated psychosocial and physical well-being during first ART treatment better than did women in a long GnRH agonist protocol. However, the one item on self-reported general quality of life was rated similarly. CLINICAL TRIAL REGISTRATION NUMBER: NCT00756028.

Evidence from a systematic review and meta-analysis of randomized controlled trials. AB - OBJECTIVE: To assess the impact of endometrial scratch injury (ESI) on the outcomes of intrauterine insemination (IUI) stimulated cycles. DESIGN: Systematic review and meta-analysis. SETTING: Not applicable. PATIENT(S): Infertile women undergoing one or more IUI stimulated cycles. INTERVENTION(S): Randomized controlled trials (RCTs) were identified by searching electronic databases. We included RCTs comparing ESI (i.e., intervention group) during the course of IUI stimulated cycle (C-ESI) or during the menstrual cycle preceding IUI treatment (P ESI) with controls (no endometrial scratch). The summary measures were reported as odds ratio (OR) with 95% confidence-interval (CI). MAIN OUTCOME MEASURE(S): Clinical pregnancy rate, ongoing pregnancy rate, multiple pregnancy rate, ectopic pregnancy rate, miscarriage rate. RESULT(S): Eight trials were included in the meta-analysis, comprising a total of 1,871 IUI cycles. Endometrial scratch injury was associated with a higher clinical pregnancy rate (OR 2.27) and ongoing pregnancy rate (OR 2.04) in comparison with the controls. No higher risk of multiple pregnancy (OR 1.09), miscarriage (OR 0.80), or ectopic pregnancy (OR 0.82) was observed in patients receiving ESI. Subgroup analysis based on ESI timing showed higher clinical pregnancy rate (OR 2.57) and ongoing pregnancy rate (OR 2.27) in patients receiving C-ESI and no advantage in patients receiving P ESI. CONCLUSION(S): Available data suggest that ESI performed once, preferably during the follicular phase of the same cycle of IUI with flexible aspiration catheters, may improve clinical pregnancy and ongoing pregnancy rates in IUI cycles. Endometrial scratch injury does not appear to increase the risk of multiple pregnancy, miscarriage, or ectopic pregnancy.

PMID- 29175071 TI - IcarisideII improves left ventricular remodeling in spontaneously hypertensive rats by inhibiting the ASK1-JNK/p38 signaling pathway. AB - Inhibition or removal of excess reactive oxygen species can effectively protect cellular function or reduce cell death because oxidative stress is the main cause of cellular damage in many diseases. The flavonoid compound IcarisideII having a slight inhibitory effect on PDE5, is the main active components of epimedium in vivo and has a wide range of pharmacological effects on oxidation and apoptosis. However, whether IcarisideII has the same protective effect on ventricular remodeling in spontaneously hypertensive rats (SHR) is unknown. We found that compared with WKY rats, SHRs exhibited noticeable arterial hypertension. Additionally, echocardiography showed that the diameter of the left ventricle was enlarged, wall thickness was increased, and ejection fraction and short axis shortening rate were reduced. H&E staining demonstrated that SHR cells were disordered and noticeably hypertrophic. Masson trichrome staining revealed significant myocardial fibrosis in the myocardium. Tunel staining indicated that 4.39 times the percent of apoptotic cells were present in SHRs compared to WKY rats. In our study, intra-gastric administration of IcarisideII decreased blood pressure, promoted heart function recovery and improved ventricular remodeling in SHRs. Additionally, it reduced myocardial fibrosis, inhibited myocardial apoptosis, decreased the generation of reactive oxygen species and improved SOD activity. IcarisideII down-regulated the activation of the oxidative stress associated proteins ASK1, p38 and JNK; inhibited the expression of p53, Bax and cleaved-caspase3 in the mitochondrial apoptosis pathway; and up-regulated the expression of Bcl-2. In conclusion, this study indicates that IcarisideII can inhibit myocardial apoptosis and improve left ventricular remodeling in SHRs. It can be inferred that this mechanism may be related to the inhibition of the ASK1 JNK/p38 signaling pathway. PMID- 29175072 TI - Capsaicin prevents mitochondrial damage, protects cardiomyocytes subjected to anoxia/reoxygenation injury mediated by 14-3-3eta/Bcl-2. AB - Capsaicin(Cap) is an active component of chili peppers that is extracted from capsicum plants. Recent studies have reported that Cap can ameliorate myocardial ischemia/reperfusion(I/R) injury. Mitochondria play an important role in pathways of apoptosis induced by myocardial I/R injury. However, the underlying mechanisms of Cap that improve mitochondrial function during I/R injury is not yet understood. The aim of this study was to evaluate whether Cap regained normal mitochondrial function in myocardial I/R injury, and to further explore the underlying mechanisms of action involved. In this study, an acute myocardial anoxia/reoxygenation(A/R) injury model was established using H9c2 cells. The cell viability was detected by MTS assay. LDH activity, mitochondrial permeability transition pores(mPTP) opening, and caspase-3 activity were analyzed using an ultra violet spectrophotometer. Levels of intracellular reactive oxygen species and apoptosis were evaluated by flow cytometry. Western blot analysis was used to determine the expression of 14-3-3eta, Bcl-2, and Bax. The data showed that pretreatment with Cap decreased LDH release and increased cell viability in H9c2 cells that underwent A/R. Cap pretreatment significantly attenuated generation of reactive oxygen species, inhibited mPTP opening and caspase-3 activation, downregulated Bax, upregulated 14-3-3eta and Bcl-2, and ultimately reduced apoptosis in H9c2 cells that underwent A/R. Moreover, 14-3-3etaRNAi adenovirus markedly eliminated the protective effects of Cap in H9c2 cells that underwent A/R. In addition, ABT-737(inhibitor of Bcl-2) significantly eliminated Cap protection. Taken together, the present study suggested that the cardioprotective effect of Cap against A/R injury involves the 14-3-3eta pathway and prevention of mitochondrial damage. PMID- 29175073 TI - Von Economo neurons of the anterior cingulate across the lifespan and in Alzheimer's disease. AB - BACKGROUND: Throughout the human aging lifespan, neurons acquire an unusually high burden of wear and tear; this is likely why age is considered the strongest risk factor for the development of Alzheimer's Disease (AD). Von Economo neurons (VENs) are rare, spindle-shaped cells mostly populated in anterior cingulate cortex. In a prior study, "SuperAgers" (individuals older than 80 years of age with outstanding memory ability) showed higher VEN densities compared to elderly controls with average memory, and those with amnestic Mild Cognitive Impairment (aMCI). The intrinsic vulnerabilities of these neurons are unclear, and their contribution to neurodegeneration is unknown. The current study investigated the influence of age and the severity of Alzheimer's disease (AD) on VEN density. METHODS: VEN and total neuronal densities were quantitated using unbiased stereological methods in the anterior cingulate cortex of postmortem samples from the following subject groups: younger controls (age 20-60), SuperAgers, cognitively average elderly controls (age 65+), individuals diagnosed antemortem with aMCI, and individuals diagnosed antemortem with dementia of AD (N = 5, per group). RESULTS: The AD group showed significantly lower VEN density compared to younger and older controls (p < .05), but not compared to the aMCI group, and VENs bearing neurofibrillary tangles were discovered in AD cases. The aMCI group showed lower VEN density than elderly controls, but this was not significant. There was a significant negative correlation between VEN density and Braak stages of AD (p < .001). Consistent with prior findings, SuperAgers showed highest mean VEN density, even when compared to younger cases. CONCLUSIONS: VENs in human anterior cingulate cortex are vulnerable to AD pathology, particularly in later stages of pathogenesis. Their densities do not change throughout aging in individuals with average cognition, and they are more numerous in SuperAgers.

AB - Infections are one of the main reasons for removal of implants from patients, and usually need difficult and expensive treatments. Staphylococcus aureus and Staphylococcus epidermidis are the most frequently detected pathogens. We reviewed the epidemiology and pathogenesis of implant-related infections. Relevant studies were identified by electronic searching of the following databases: PubMed, ScienceDirect, Academic Google, and CAPES Journal Portal. This review reports epidemiological studies of implant infections caused by S. aureus and S. epidermidis. We discuss some methodologies used in the search for new compounds with antibiofilm activity and the main strategies for biomaterial surface modifications to avoid bacterial plaque formation and consequent infection. S. aureus and S. epidermidis are frequently involved in infections in catheters and orthopaedic/breast implants. Different methodologies have been used to test the potential antibiofilm properties of compounds; for example, crystal violet dye is widely used for in-vitro biofilm quantification due to its low cost and good reproducibility. Changes in the surface biomaterials are necessary to prevent biofilm formation. Some studies have investigated the immobilization of antibiotics on the surfaces of materials used in implants. Other approaches have been used as a way to avoid the spread of bacterial resistance to antimicrobials, such as the functionalization of these surfaces with silver and natural compounds, as well as the electrical treatment of these substrates.

PMID- 29175077 TI - Detection limit of Mycobacterium chimaera in water samples for monitoring medical device safety: insights from a pilot experimental series. AB - BACKGROUND: A growing number of Mycobacterium chimaera infections after cardiosurgery have been reported by several countries. These potentially fatal infections were traced back to contaminated heater-cooler devices (HCDs), which use water as a heat transfer medium. Aerosolization of water contaminated with M. chimaera from HCDs enables airborne transmission to patients undergoing open chest surgery. Infection control teams test HCD water samples for mycobacterial growth to guide preventive measures. The detection limit of M. chimaera in water samples, however, has not previously been investigated. AIM: To determine the detection limit of M. chimaera in water samples using laboratory-based serial dilution tests. METHODS: An M. chimaera strain representative of the international cardiosurgery-associated M. chimaera outbreak was used to generate a logarithmic dilution series. Two different water volumes, 50 and 1000mL, were inoculated, and, after identical processing (centrifugation, decantation, and decontamination), seeded on mycobacteria growth indicator tube (MGIT) and Middlebrook 7H11 solid media. FINDINGS: MGIT consistently showed a lower detection limit than 7H11 solid media, corresponding to a detection limit of >=1.44 * 104cfu/mL for 50mL and >=2.4cfu/mL for 1000mL water samples. Solid media failed to detect M. chimaera in 50mL water samples. CONCLUSION: Depending on water volume and culture method, major differences exist in the detection limit of M. chimaera. In terms of sensitivity, 1000mL water samples in MGIT media performed best. Our results have important implications for infection prevention and control strategies in mitigation of the M. chimaera outbreak and healthcare water safety in general. PMID- 29175078 TI - Limbic brain structures and burnout-A systematic review. AB - More profound understanding of the relationship between the burnout and the limbic system function can provide better insight into brain structures associated with the burnout syndrome. The objective of this review is to explore all evidence of limbic brain structures associated with the burnout syndrome. In total, 13 studies were selected. Four of them applied the neuroimaging technology to investigate the sizes/volumes of the limbic brain structures of burnout patients. Six other studies were to investigate the hypothalamus-pituitary adrenal (HPA) axis of burnout patients. Based on the results of the studies on the HPA-axis and neuroimaging of the limbic brain structures, one can see great impact of the chronic occupational stress on the limbic structures in terms of HPA dysregulation, a decrease of BDNF, impaired neurogenesis and limbic structures atrophy. It can be concluded that chronic stress inhibits the feedback control pathway in the HPA axis, causes the decrease of brain-derived neurotrophic factor (BDNF), then impaired neurogenesis and eventually neuron atrophy. PMID- 29175079 TI - Semiconducting polymer-based nanoparticles with strong absorbance in NIR-II window for in vivo photothermal therapy and photoacoustic imaging. AB - Near-infrared (NIR) light-induced photothermal therapy (PTT) has attracted much interest in recent years. In the NIR region, tissue penetration ability of the second biological near-infrared window (1000-1350 nm) is recognized to be stronger than that of the first window (650-950 nm). However, NIR light absorbers in the second NIR region (NIR-II) have been scant even though various NIR light absorbers in the first NIR region (NIR-I) have been widely explored. In this work, a thieno-isoindigo derivative-based semiconducting polymer, PBTPBF-BT, were formulated into PEGylated nanoparticles. The obtained nanoparticle NPPBTPBF-BT exhibited strong absorption in NIR-II region, inherent high photothermal conversion efficacy, and excellent photostability. The in vitro and in vivo PTT study employing 1064 nm laser in NIR-II window revealed that NPPBTPBF-BT could efficiently ablate tumor cell at a power density of 0.42 W/cm2 (the skin tolerance threshold value). Moreover, NPPBTPBF-BT with excellent photostability exhibited enhanced photoacoustic (PA) imaging of tumor in living mice, suggesting the great probability of using NPPBTPBF-BT for in vivo PA imaging-guided PTT in the NIR-II window. PMID- 29175080 TI - Targeted iron nanoparticles with platinum-(IV) prodrugs and anti-EZH2 siRNA show great synergy in combating drug resistance in vitro and in vivo. AB - Resistance to platinum agents is challenging in cancer treatment with platinum drugs. Such resistant cells prevent effective platinum accumulation intracellular and alter cellular adaptations to survive from cytotoxicity by regulating corresponding proteins expression. Ideal therapeutics should combine resolution to these pump and non-pump relevant resistance of cancer cells to achieve high efficacy and low side effect. Fe3O4 nanocarrier loaded with drugs could enter cells in a more efficient endocytosis manner which circumvents pump-relevant drug resistance. EZH2 protein which was previously found to be over-expressed in drug resistant cancer cells was reported to be involved in platinum drug resistance and play a vital role in anti-apoptosis pathways. Here, we report Fe3O4 nanoparticles loaded with siEZH2 (siRNA), a platinum prodrug in +4 oxidation state (cis, cis, trans-diamminedichlorodisuccinato-platinum-(IV), namely Pt(IV)) and luteinizing hormone-releasing hormone (LHRH) targeting polypeptides. Results show that targeted nanoparticles loading with siEZH2 synergize with Pt(IV) and result in similar cell killing performance to A2780/DDP cells (cisplatin resistant) compared with non-siEZH2 loaded nanoparticles to A2780 cells (cisplatin sensitive). Thus, this Fe3O4@PEI-Pt(IV)-PEG-LHRH@siEZH2 nanoparticles reverse the cisplatin resistance from the pump and non-pump relevant aspects, fully taking advantage of nanocarrier system. PMID- 29175082 TI - SnWO4-based nanohybrids with full energy transfer for largely enhanced photodynamic therapy and radiotherapy. AB - The "partial matching" between upconversion nanoparticle (UCNP) emission and absorption by photosensitizers (PSs) often leads to a theoretically reduced therapeutic efficiency in UC-based photodynamic therapy (PDT) strategies in which the chosen PSs have limited capabilities and are unable to utilize all the near infrared-upconverted light. In this study, needle-like SnWO4 nanocrystals (SWs) with a broad UV-vis absorption region were synthesized to solve the problem. After covalent conjugation with UCNPs, all the UCNP-emitted light was effectively absorbed by SWs, triggering the type-I PDT process to activate ROS maxima. The unique nanostructure of the as-formed UCNP-SnWO4 nanohybrids (USWs) also enhanced the receiving light intensities of SW, which further boosted the antitumor efficacy. Meanwhile, the strong X-ray attenuation capacity of both tungsten and tin elements qualified the USWs as excellent radio-sensitizers for radiotherapy (RT) enhancement, which played a complementary role with PDT treatment because PDT-mediated induction arrested the cells in the G0-G1 cell cycle phase, and RT was more damaging toward cells in the G2/M phase. The remarkably enhanced UC PDT/RT efficiency of USWs was next validated in vitro and in vivo, and the combined NIR light and ionizing irradiation treatment completely suppressed tumor growth, revealing its great potential as an efficient anticancer therapeutic agent against solid tumors. PMID- 29175081 TI - Epithelial-mesenchymal crosstalk influences cellular behavior in a 3D alveolus fibroblast model system. AB - Interactions between lung epithelium and interstitial fibroblasts are increasingly recognized as playing a major role in the progression of several lung pathologies, including cancer. Three-dimensional in vitro co-culture systems offer tissue-relevant platforms to study the signaling interplay between diseased and healthy cell types. Such systems provide a controlled environment in which to probe the mechanisms involved in epithelial-mesenchymal crosstalk. To recapitulate the native alveolar tissue architecture, we employed a cyst templating technique to culture alveolar epithelial cells on photodegradable microspheres and subsequently encapsulated the cell-laden spheres within poly (ethylene glycol) (PEG) hydrogels containing dispersed pulmonary fibroblasts. A fibroblast cell line (CCL-210) was co-cultured with either healthy mouse alveolar epithelial primary cells or a cancerous alveolar epithelial cell line (A549) to probe the influence of tumor-stromal interactions on proliferation, migration, and matrix remodeling. In 3D co-culture, cancerous epithelial cells and fibroblasts had higher proliferation rates. When examining fibroblast motility, the fibroblasts migrated faster when co-cultured with cancerous A549 cells. Finally, a fluorescent peptide reporter for matrix metalloproteinase (MMP) activity revealed increased MMP activity when A549s and fibroblasts were co cultured. When MMP activity was inhibited or when cells were cultured in gels with a non-degradable crosslinker, fibroblast migration was dramatically suppressed, and the increase in cancer cell proliferation in co-culture was abrogated. Together, this evidence supports the idea that there is an exchange between the alveolar epithelium and surrounding fibroblasts during cancer progression that depends on MMP activity and points to potential signaling routes that merit further investigation to determine targets for cancer treatment. PMID- 29175083 TI - Development of a theranostic prodrug for colon cancer therapy by combining ligand targeted delivery and enzyme-stimulated activation. AB - The high incidence of colorectal cancer worldwide is currently a major health concern. Although conventional chemotherapy and surgery are effective to some extent, there is always a risk of relapse due to associated side effects, including post-surgical complications and non-discrimination between cancer and normal cells. In this study, we developed a small molecule-based theranostic system, Gal-Dox, which is preferentially taken up by colon cancer cells through receptor-mediated endocytosis. After cancer-specific activation, the active drug Dox (doxorubicin) is released with a fluorescence turn-on response, allowing both drug localization and site of action to be monitored. The therapeutic potency of Gal-Dox was also evaluated, both in vivo and ex vivo, thus illustrating the potential of Gal-Dox as a colorectal cancer theranostic with great specificity. PMID- 29175085 TI - Ventilator Management and Respiratory Care After Cardiac Arrest: Oxygenation, Ventilation, Infection, and Injury. AB - Return of spontaneous circulation after cardiac arrest results in a systemic inflammatory state called the post-cardiac arrest syndrome, which is characterized by oxidative stress, coagulopathy, neuronal injury, and organ dysfunction. Perturbations in oxygenation and ventilation may exacerbate secondary injury after cardiac arrest and have been shown to be associated with poor outcome. Further, patients who experience cardiac arrest are at risk for a number of other pulmonary complications. Up to 70% of patients experience early infection after cardiac arrest, and the respiratory tract is the most common source. Vigilance for early-onset pneumonia, as well as aggressive diagnosis and early antimicrobial agent administration are important components of critical care in this population. Patients who experience cardiac arrest are at risk for the development of ARDS. Risk factors include aspiration, pulmonary contusions (from chest compressions), systemic inflammation, and reperfusion injury. Early evidence suggests that they may benefit from ventilation with low tidal volumes. Meticulous attention to mechanical ventilation, early assessment and optimization of respiratory gas exchange, and therapies targeted at potential pulmonary complications may improve outcomes after cardiac arrest. PMID- 29175084 TI - Manipulating human dendritic cell phenotype and function with targeted porous silicon nanoparticles. AB - Dendritic cells (DC) are the most potent antigen-presenting cells and are fundamental for the establishment of transplant tolerance. The Dendritic Cell Specific Intracellular adhesion molecule-3-Grabbing Non-integrin (DC-SIGN; CD209) receptor provides a target for dendritic cell therapy. Biodegradable and high surface area porous silicon (pSi) nanoparticles displaying anti-DC-SIGN antibodies and loaded with the immunosuppressant rapamycin (Sirolimus) serve as a fit-for-purpose platform to target and modify DC. Here, we describe the fabrication of rapamycin-loaded DC-SIGN displaying pSi nanoparticles, the uptake efficiency into DC and the extent of nanoparticle-induced modulation of phenotype and function. DC-SIGN antibody displaying pSi nanoparticles favourably targeted and were phagocytosed by monocyte-derived and myeloid DC in whole human blood in a time- and dose-dependent manner. DC preconditioning with rapamycin-loaded nanoparticles, resulted in a maturation resistant phenotype and significantly suppressed allogeneic T-cell proliferation. PMID- 29175086 TI - Re-examining Permissive Hypercapnia in ARDS: A Narrative Review. AB - Lung-protective ventilation (LPV) has become the cornerstone of management in patients with ARDS. A subset of patients is unable to tolerate LPV without significant CO2 elevation. In these patients, permissive hypercapnia is used. Although thought to be benign, it is becoming increasingly evident that elevated CO2 levels have significant physiological effects. In this narrative review, we highlight clinically relevant end-organ effects in both animal models and clinical studies. We also explore the association between elevated CO2, acute cor pulmonale, and ICU mortality. We conclude with a brief review of alternative therapies for CO2 management currently under investigation in patients with moderate to severe ARDS. PMID- 29175087 TI - Iso-risk air no decompression limits after scoring marginal decompression sickness cases as non-events. AB - Decompression sickness (DCS) in humans is associated with reductions in ambient pressure that occur during diving, aviation, or certain manned spaceflight operations. Its signs and symptoms can include, but are not limited to, joint pain, radiating abdominal pain, paresthesia, dyspnea, general malaise, cognitive dysfunction, cardiopulmonary dysfunction, and death. Probabilistic models of DCS allow the probability of DCS incidence and time of occurrence during or after a given hyperbaric or hypobaric exposure to be predicted based on how the gas contents or gas bubble volumes vary in hypothetical tissue compartments during the exposure. These models are calibrated using data containing the pressure and respired gas histories of actual exposures, some of which resulted in DCS, some of which did not, and others in which the diagnosis of DCS was not clear. The latter are referred to as marginal DCS cases. In earlier works, a marginal DCS event was typically weighted as 0.1, with a full DCS event being weighted as 1.0, and a non-event being weighted as 0.0. Recent work has shown that marginal DCS events should be weighted as 0.0 when calibrating gas content models. We confirm this indication in the present work by showing that such models have improved performance when calibrated to data with marginal DCS events coded as non-events. Further, we investigate the ramifications of derating marginal events on model prescribed air diving no-stop limits. PMID- 29175088 TI - Constitutive up-regulation of Turandot genes rather than changes in acclimation ability is associated with the evolutionary adaptation to temperature fluctuations in Drosophila simulans. AB - Most research on thermal adaptation of ectotherms is based on experiments performed at constant temperatures. However, for short-lived insects daily fluctuations of temperature could be an important environmental parameter involved in evolutionary adaptation to thermal heterogeneity. In this study we investigated the mechanisms underlying evolutionary adaptation to daily fluctuating temperatures. We studied replicated selection lines of Drosophila simulans evolved in a constant or a daily fluctuating thermal regime. Previous studies of these lines have shown clear acclimation benefits to heat tolerance induced by the fluctuating regime. First, we tested the existence of an evolved circadian controlled adjustment of heat resistance in selected flies. This was done by investigating the daily variation in time to heat knockdown in flies from both selection regimes when exposed to either a constant or a daily fluctuating thermal regime for a single generation. While daily variation in heat resistance was found, the results suggest that there was neither an evolved adaptive circadian controlled adjustment of heat resistance nor a continuous acclimation response induced by fluctuating temperatures in these lines. Second, in order to reveal functional candidates for adaptation to the fluctuating thermal regime, we investigated the global transcriptomic response to a high temperature exposure in flies from both regimes. We found that flies selected both in constant and fluctuating thermal regimes responded similarly to increasing temperature. However, we found that evolutionary adaptation to the fluctuating thermal regime led to transcriptional enrichment of the GO terms eggshell chorion assembly and cellular response to heat. The latter category was constituted by a constitutive up-regulation of four Turandot genes and not heat shock protein genes, suggesting that Turandot genes could play a prominent role for adaptation to daily fluctuating thermal conditions. PMID- 29175089 TI - Effects of gender, age, and nutrition on circadian locomotor activity rhythms in the flesh fly Sarcophaga crassipalpis. AB - In many animal species, circadian rhythms of behavior are not constant throughout the lifetime of the individual but rather exhibit at least some degree of plasticity. In the present study, we have examined the potential influences of gender, age, and nutrition (presence or absence of liver) on the expression of circadian locomotor activity rhythms in the flesh fly Sarcophaga crassipalpis. We found no significant differences in endogenous circadian period under constant dark conditions with respect to gender, nutrition, or age for the duration of our experiments. On the other hand, both male and female flesh flies, as expected, were predominantly diurnal under light-dark cycles, but the pattern of entrainment differed between the sexes. Females also displayed higher activity levels than males. Also, in contrast with males, female activity levels increased with age. Moreover, females exhibited an extraordinary, but transient (one to three days), departure from diurnality which we characterize as "extended dark activity" (EDA). This phenomenon appeared as a continuous bout of locomotor activity that extended at least three hours into the early half of the dark phase at levels at least twice the median of the overall locomotor activity for the individual fly. EDA occurred as an age-dependent response to liver consumption, never appearing prior to day 4 post-eclosion but, thereafter, transpiring within one or two days after a 48-h exposure to liver. These results suggest a linkage between physiological events associated with egg provisioning and locomotor activity in the anautogenous flesh fly. Furthermore, our findings identify the existence of multiple influences on the expression of circadian clock-regulated behavior. PMID- 29175091 TI - Phosphoprotein DIGE profiles reflect blast differentiation, cytogenetic risk stratification, FLT3/NPM1 mutations and therapy response in acute myeloid leukaemia. AB - : Acute myeloid leukaemia (AML) is an aggressive blood cancer characterized by a distinct block in differentiation of myeloid progenitors, recurrent chromosomal translocations and gene mutations of which >50% involve signal transduction through dysregulated kinases and phosphatases. In search for novel protein biomarkers for disease stratification we investigated the phosphoproteome in leukaemic cells from 62 AML patients at time of diagnosis using immobilized metal affinity chromatography, protein separation by two-dimensional differential gel electrophoresis (2D-DIGE) and mass spectrometry before validation by selected reaction monitoring (SRM). Unsupervised clustering found 27 phosphoproteins significantly discriminating patients according to leukaemic cell differentiation (French-American-British (FAB) classification), cytogenetic and mutational (FLT3, NPM1) status or response to chemotherapy. Monocytic differentiation (FAB M4-M5) correlated with enrichment of proteins involved in apoptosis (MOES, ANXA5 and EFHD2). TALDO, a protein associated with thrombocytopenia if down-regulated, was elevated in patients with wild type NPM1 compared to patients with NPM1 mutation. This study demonstrates the potential of quantitative proteomics in AML classification and risk stratification. BIOLOGICAL SIGNIFICANCE: Patients diagnosed with AML are currently categorized according to cellular morphology, cytogenetic alterations and mutations, although the majority of these cellular and genetic alterations have no or unsolved impact on therapy selection or prognosis. We therefore explored the phosphoproteome for abundance changes associated with traditional classifiers to unravel patterns that could stratify patients at the protein level. MOES, ANXA5 and EFHD2 were confirmed by SRM to be correlated to monocytic differentiation, whilst TALDO was elevated in NPM1 wild type patients. PMID- 29175090 TI - Effect of fibrinogen, fibrin, and fibrin degradation products on transendothelial migration of leukocytes. AB - In spite of numerous studies on the involvement of fibrinogen in transendothelial migration of leukocytes and thereby inflammation, there is still no clear understanding of which fibrin(ogen) species can stimulate leukocyte transmigration. Although we have previously proposed that interaction of fibrin with the VLDL receptor (VLDLR) promotes leukocyte transmigration, there is no direct experimental evidence for the involvement of fibrin in this process. To address these questions, we performed systematic studies of interaction of VLDLR with fibrinogen, fibrin, and their isolated recombinant BbetaN- and betaN domains, respectively, and the effect of various fibrin(ogen) species on transendothelial migration of leukocytes. The results obtained revealed that freshly purified fibrinogen does not interact with VLDLR in solution and has practically no effect on leukocyte transmigration. They also indicate that the VLDLR-binding site is cryptic in fibrinogen and becomes accessible upon its adsorption onto a surface or upon its conversion into fibrin. We also found that the D-D:E1 complex and higher molecular mass fibrin degradation products, as well as soluble fibrin and fibrin polymers (clots) anchored to the endothelial monolayer, promote leukocyte transmigration mainly through the VLDL receptor dependent pathway. Thus, the results of the present study suggest that fibrin degradation products and soluble fibrin that may be present in the circulation in vivo, as well as fibrin clots that may be deposited on the surface of inflamed endothelium, promote leukocyte transmigration. These findings further clarify the molecular mechanisms underlying the fibrin-VLDLR-dependent pathway of leukocyte transmigration and provide an explanation for a possible (patho)physiological role of this pathway. PMID- 29175092 TI - Differences in resistance to nitrogen and phosphorus deficiencies explain male biased populations of poplar in nutrient-deficient habitats. AB - : In most forest soils, the availability of nitrogen (N) and phosphorus (P) nutrients is low and unable to meet the requirement of tree growth. In the past decades, sex-based differences in poplar have been investigated in morphology and physiology. Proteomic techniques provide new insights into sex-specific differences at the molecular level. This review gives a comparative overview of the effects of N and P deficiencies on poplar physiological and proteomic characteristics. Male poplars are more efficient at photosynthesis and nutrient usage than females. Proteins related to carbohydrate metabolism, defence responses and transcription and translation processes are changed to adapt diversely in males and females. These results provide evidence that male poplar have better resistance to nutrient-limiting conditions than females, which may be reasonable for the male-biased sex ratio in nutrient-deficient habitats. Furthermore, this review also discusses the potential growth-defence trade-offs in male and female poplar coping with nutrient limitations. BIOLOGICAL SIGNIFICANCE: In the past decades, the physiological and molecular responses of individual trees exposed to nutrient deficiency have been well studied. An important model woody plant, Populus, is dioecious and shows a male-biased sex ratio in nutrient-deficient habitats. Individually, different responses to nutrient limitation between the sexes determine the bias of population sex ratios. Proteomic techniques provide new insights into sex-based differences in the molecular mechanisms underlying nutrient deficiency. This review gives a comparative overview of the identification of nitrogen and phosphorus deficiency effects on physiological and proteomic characteristics. Male poplars are more resistant and have a smaller range of protein changes than females in response to N and P deficiency, which explains the observed male-biased sex ratios to a certain extent. Furthermore, this review also discusses the possible growth defense trade-offs in male and female poplars coping with nutrient deficiency. PMID- 29175093 TI - The blind mind: No sensory visual imagery in aphantasia. AB - For most people the use of visual imagery is pervasive in daily life, but for a small group of people the experience of visual imagery is entirely unknown. Research based on subjective phenomenology indicates that otherwise healthy people can completely lack the experience of visual imagery, a condition now referred to as aphantasia. As congenital aphantasia has thus far been based on subjective reports, it remains unclear whether individuals are really unable to imagine visually, or if they have very poor metacognition - they have images in their mind, but are blind to them. Here we measured sensory imagery in subjectively self-diagnosed aphantasics, using the binocular rivalry paradigm, as well as measuring their self-rated object and spatial imagery with multiple questionnaires (VVIQ, SUIS and OSIQ). Unlike, the general population, experimentally naive aphantasics showed almost no imagery-based rivalry priming. Aphantasic participants' self-rated visual object imagery was significantly below average, however their spatial imagery scores were above average. These data suggest that aphantasia is a condition involving a lack of sensory and phenomenal imagery, and not a lack of metacognition. The possible underlying neurological cause of aphantasia is discussed as well as future research directions. PMID- 29175094 TI - Application of optimal control to the onchocerciasis transmission model with treatment. AB - In this paper, we present a model for onchocerciasis that considers mass administration of ivermectin, contact prevention controls and vector elimination. The model equilibria are computed and stability analysis carried out in terms of the basic reproduction number R0. The model is found to exhibit a backward bifurcation so that for R0 less than unity is not sufficient to eradicate the disease from the population and the need is to lower R0 to below a certain threshold, R0c for effective disease control. The model is fitted to data on individuals with onchocerciasis in Ghana. A sensitivity analysis reveals that the parameters with the most control over the epidemic are the vector death rate and the effective contact rates between susceptible individuals and infected vector and susceptible vector with infected individuals. This suggests that programs aimed controlling vector will be significantly more effective in combating the disease. Optimal control theory is applied to investigate optimal control strategies for controlling onchocerciasis using insect repellent and both insecticide and larvicide as system control variables. We use Pontryagin's Maximum Principle to show the necessary conditions for the optimal control of onchocerciasis. Numerical simulations of the model show that restricted and proper use of control measures might considerably decrease the number of infections in the human population.

AB - The evolutionary history of Quercus section Cyclobalanopsis, a dominant lineage in East Asian evergreen broadleaved forests (EBLFs), has not been comprehensively studied using molecular tools. In this study, we reconstruct the first comprehensive phylogeny of this lineage using a genomic approach (restriction site associated DNA sequencing, RAD-seq), sampling 35 of the ca. 90 species currently recognized, representing all main morphological groups of section Cyclobalanopsis. In addition, 10 other species of Quercus and two outgroups were also sampled. Divergence times were estimated using a relaxed clock model and two fossil calibrations. Ancestral areas and dispersal routes were inferred using statistical dispersal-vicariance analysis and the dispersal-extinction cladogenesis (DEC) model. The phylogeny of Quercus section Cyclobalanopsis demonstrates the section to be monophyletic, comprising two main lineages and six subclades that are well supported by anatomical traits. Biogeographical reconstructions indicate that the wide northern hemisphere distribution of Quercus was disrupted in the Late Eocene, leading to the main extant groups at about 33 Ma. The earliest divergences in section Cyclobalanopsis correspond to the phased uplift of the Himalayas and lateral extrusion of Indochina at the transition of the Oligocene and Miocene, where the highest rate of diversification occurred in the late Miocene. Dispersal from Sino-Himalaya and the Palaeotropics to Sino-Japan in the Miocene was facilitated by the increased intensity of East Asian summer monsoons and by the Middle Miocene Climatic Optimum. Our results highlight the importance of climatic changes and Indo Eurasian collision-induced tectonic activities from the Neogene onward to the spatial-temporal diversification patterns of Asian EBLF lineages. PMID- 29175096 TI - Budgetary Impact of Telotristat Ethyl, a Novel Treatment for Patients with Carcinoid Syndrome Diarrhea: A US Health Plan Perspective. AB - PURPOSE: Telotristat ethyl (TE) was recently approved for carcinoid syndrome diarrhea (CSD) in patients not adequately controlled with somatostatin analog long-acting release (SSA LAR) therapy alone. A budget impact model was developed to determine the short-term affordability of reimbursing TE in a US health plan. METHODS: A budget impact model compared health care costs when CSD is managed per current treatment patterns (SSA LAR, reference drug scenario) versus when TE is incorporated in the treatment algorithm (SSA LAR + TE, new drug scenario). Prevalence of CSD, proportion of patients not adequately controlled on SSA LAR, monthly treatment costs (pharmacy and medical), and treatment efficacy were derived from the literature. In the reference drug scenario, an escalated monthly dose of SSA LAR therapy of 40 mg was assumed to treat patients with CSD not adequately controlled on the labeled dose of SSA LAR. In the new drug scenario, TE was added to the maximum labeled monthly dose of SSA LAR therapy of 30 mg. The incremental budget impact was calculated based on an assumed TE market uptake of 28%, 42%, and 55% during Years 1, 2, and 3, respectively. One-way sensitivity analyses were conducted to test model assumptions. FINDINGS: A hypothetical health plan of 1 million members was estimated to have 42 prevalent CSD patients of whom 17 would be inadequately controlled on SSA LAR therapy. The monthly medical cost per patient not adequately controlled on SSA LAR in addition to pharmacotherapy was estimated to be $3946 based on the literature. Based on the observed treatment response in a clinical trial of 20% and 44% for the base case reference and new drug scenarios, total per patient per month costs were estimated to be $7563 and $11,205, respectively. Total annual costs in the new drug scenario were estimated to be $2.3 to $2.5 million during the first 3 years. The overall incremental annual costs were estimated to be $154,000 in Year 1, $231,000 in Year 2, and $302,000 in Year 3. This translated to an incremental per patient per month cost of $0.013, $0.019, and $0.025 for Years 1, 2, and 3. These results remained robust in 1-way sensitivity analyses. IMPLICATIONS: The availability of TE for patients not adequately controlled on SSA LAR therapy provides a novel treatment option for CSD. This model showed that providing access to this first-in-class oral agent would have a minimal budget impact to a US health plan. PMID- 29175097 TI - Cost-effectiveness of Paclitaxel + Ramucirumab Combination Therapy for Advanced Gastric Cancer Progressing After First-line Chemotherapy in Japan. AB - PURPOSE: The combination of paclitaxel + ramucirumab is a standard second-line treatment in patients with advanced gastric cancer. This therapy has been associated with increased median overall survival and progression-free survival compared with those with paclitaxel monotherapy. We evaluated the cost effectiveness of paclitaxel + ramucirumab combination therapy in patients with advanced gastric cancer, from the perspective of health care payers in Japan. METHODS: We constructed a Markov model to compare, over a time horizon of 3 years, the costs and effectiveness of the combination of paclitaxel + ramucirumab and paclitaxel alone as second-line therapies for advanced gastric cancer in Japan. Health outcomes were measured in life-years (LYs) and quality-adjusted (QA) LYs gained. Costs were calculated using year-2016 Japanese yen (Y1 = US $17.79) according to the social insurance reimbursement schedule and drug tariff of the fee-for-service system in Japan. Model robustness was addressed through 1 way and probabilistic sensitivity analyses. The costs and QALYs were discounted at a rate of 2% per year. The willingness-to-pay threshold was set at the World Health Organization's criterion of Y12 million, because no consensus exists regarding the threshold for acceptable cost per QALY ratios in Japan's health policy. FINDINGS: Paclitaxel + ramucirumab combination therapy was estimated to provide an additional 0.09 QALYs (0.10 LYs) at a cost of Y3,870,077, resulting in an incremental cost-effectiveness ratio of Y43,010,248/QALY. The incremental cost effectiveness ratio for the combination therapy was >Y12 million/QALY in all of the 1-way and probabilistic sensitivity analyses. IMPLICATIONS: Adding ramucirumab to a regimen of paclitaxel in the second-line treatment of advanced gastric cancer is expected to provide a minimal incremental benefit at a high incremental cost per QALY. Based on our findings, adjustments in the price of ramucirumab, as well as improves in other clinical parameters such as survival time and adverse event in advanced gastric cancer therapy, are needed. PMID- 29175098 TI - Model-based tracking of the bones of the foot: A biplane fluoroscopy validation study. AB - Measuring foot kinematics using optical motion capture is technically challenging due to the depth of the talus, small bone size, and soft tissue artifact. We present a validation of our biplane X-ray system, demonstrating its accuracy in tracking the foot bones directly. Using an experimental linear/rotary stage we imaged pairs of tali, calcanei, and first metatarsals, with embedded beads, through 30 poses. Model- and bead-based algorithms were employed for semi automatic tracking. Translational and rotational poses were compared to the experimental stage (a reference standard) to determine registration performance. For each bone, 10 frames per pose were analyzed. Model-based: The resulting overall translational bias of the six bones was 0.058 mm with a precision of +/- 0.049 mm. The overall rotational bias of the six bones was 0.42 degrees with a precision of +/- 0.41 degrees . Bead-based: the overall translational bias was 0.037 mm with a precision of +/- 0.032 mm and for rotation was 0.29 degrees with a precision of +/- 0.26 degrees . We validated the accuracy of our system to determine the spatial position and orientation of isolated foot bones, including the talus, calcaneus, and first metatarsal over a range of quasi-static poses. Although the accuracy of dynamic motion was not assessed, use of an experimental stage establishes a reference standard. PMID- 29175099 TI - Ground-glass nodule segmentation in chest CT images using asymmetric multi-phase deformable model and pulmonary vessel removal. AB - We propose a ground-glass nodule (GGN) segmentation method that can separate solid component and ground-glass opacity (GGO) using an asymmetric multi-phase deformable model in chest CT images. First, initial solid component and GGO were extracted using intensity-based segmentation with histogram modeling. Second, the initial extracted regions were refined using an asymmetric multi-phase deformable model with modified energy functional and intensity-constrained averaging function. Finally, vessel-like structures are removed based on multi-scale shape analysis. In experiments, the segmentation accuracy of the entire GGN was evaluated using datasets from SNUH and LIDC/IDRI. The average DSC values of Seoul National University Hospital (SNUH) and Lung Image Database Consortium and Image Database Resource Initiative (LIDC/IDRI) were 0.85 +/- 0.05 and 0.78 +/- 0.07, respectively. The Pearson's correlation coefficient (r) between segmented volumes by the proposed method and manual segmentation was evaluated using SNUH dataset. The r of solid component, GGO, and entire GGN were 0.931, 0.875 and 0.907. Our experimental results show that the proposed method improves segmentation accuracy by applying the proposed asymmetric multiphase deformable model and pulmonary vessel removal. PMID- 29175100 TI - Computational modeling of drug transport across the in vitro cornea. AB - A novel quasi-3D (Q3D) modeling approach was developed to model networks of one dimensional structures like tubes and vessels common in human anatomy such as vascular and lymphatic systems, neural networks, and respiratory airways. Instead of a branching network of the same tissue type, this approach was extended to model an interconnected stack of different corneal tissue layers with membrane junction conditions assigned between the tissues. The multi-laminate structure of the cornea presents a unique barrier design and opportunity for investigation using Q3D modeling. A Q3D model of an in vitro rabbit cornea was created to simulate the drug transport across the cornea, accounting for transcellular and paracellular pathways of passive and convective drug transport as well as physicochemistry of lipophilic partitioning and protein binding. Lipophilic Rhodamine B and hydrophilic fluorescein were used as drug analogs. The model predictions for both hydrophilic and lipophilic tracers were able to match the experimental measurements along with the sharp discontinuities at the epithelium stroma and stroma-endothelium interfaces. This new modeling approach was successfully applied towards pharmacokinetic modeling for use in topical ophthalmic drug design. PMID- 29175101 TI - Direct modeling of blood flow through the vascular network of the germinal matrix. AB - A premature birth, before completion of the 32nd pregnancy week, increases the risk of cerebral hemorrhage. The cause of brain bleeding is very often the germinal matrix of the immature brain. The germinal matrix consists of richly vascularized neuroepithelial cells and is located over the lower part of the head of the caudate nucleus. By 32-36 gestation weeks, the germinal matrix essentially disappears so that its hemorrhage is a disease of premature infants. The aim of this paper consists in developing a model of the brain vascular network and computing the pressure distribution in the germinal matrix, particularly near arterioles and venules, where cerebral hemorrhage may occur. Capillary networks consisting of several millions of vessels are directly simulated in the present study. PMID- 29175102 TI - Altered lipid properties of the stratum corneum in Canine Atopic Dermatitis. AB - Skin barrier disruption plays a role in the pathogenesis of atopic dermatitis (AD) in humans. However, little is known about skin barrier (dys-) function in Canine Atopic Dermatitis. The properties of lipids located in the outermost layer of the skin, the stratum corneum (SC) are considered to be important for the barrier. In the present study the lipid composition and lipid organization of the SC of AD dogs and control dogs were examined. The lipid composition of lesional AD skin as compared to control skin, showed a reduced free fatty acid level and a decreased ratio of ceramide[NS] C44/C34, in which C44 and C34 are the total numbers of carbon atoms of the sphingosine (S) and non-hydroxy (N) acyl chains. As a consequence of the observed changes in lipid composition in AD lesional skin the lamellar organization of lipids altered and a shift from orthorhombic to hexagonal lipid packing was monitored. Simultaneously an increased conformational disordering occurred. These changes are expected to compromise the integrity of the skin barrier. The C44/C34 chain length ratio of ceramide[NS] also showed a decreasing nonlinear relationship with the AD severity score (CADESI). Taken together, canine atopic skin showed alterations in SC lipid properties, similar to the changes observed in atopic dermatitis in humans, that correlated with a disruption of the skin barrier. Hence lipids play an important role in the pathogenesis of Canine Atopic Dermatitis. PMID- 29175103 TI - Antioxidant activity of hydroxytyrosyl esters studied in liposome models. AB - The properties and the antioxidant activity of a series of hydroxytyrosyl esters having different carbon chain lengths (C4, C8, C12 and C18) have been measured in phosphatidylcholine model membrane (liposomes) using specific probes for the bilayer and liposome lumen microenvironment, i.e., 1,6-diphenyl-1,3,5-hexatriene (DPH) and 2',7'-dichlorodihydrofluorescein (H2DCF), respectively. Antioxidants self-assembly and their interaction with liposomes has been evaluated by light scattering, fluorescence, turbidimetry, gel filtration chromatography and microfiltration measurements, allowing the determination of critical aggregation concentration, bound fraction, capacity of crossing the lipid bilayer. The distribution of hydroxytyrosyl long chain esters has been proved to depend quite specifically on their lipophilic chain length, and this turns to have deep effects on their antioxidant behaviour. Shedding new light on the cut off effect and antioxidant behaviour of phenolipids, this study also put forward the relevance of cell-free liposome-based cellular models, like giant liposomes, for further characterization of analogous systems. PMID- 29175104 TI - Cramps frequency and severity are correlated with small and large nerve fiber measures in type 1 diabetes. AB - OBJECTIVES: To explore the correlations between different muscle cramp characteristics including cramp frequency and severity and clinical and large and small nerve fiber measures in patients with diabetes type 1 (DM 1) and 2 (DM 2). METHODS: Prospective cross sectional study of healthy controls and patients with DM 1 and DM 2 recruited between April 2009 and November 2012. Participants underwent clinical evaluation and large and small nerve fiber studies, and the frequency and correlations of muscle cramps were explored. RESULTS: 37 controls, 51 patients with DM 1, and 69 patients with DM 2 were studied. Muscle cramps were the most frequent symptom captured by the Toronto Clinical Neuropathy Score (TCNS) in all groups, up to 78% in patients with DM 2. In patients with DM 1, but not DM 2, muscle cramp frequency and severity were correlated with clinical (TCNS) and both large (electrophysiology and vibration perception thresholds) and small nerve fiber measures. CONCLUSIONS: Muscle cramps are frequent in diabetes and are correlated with clinical and both small and large nerve fiber measures in DM 1, suggesting that their origin and propagation might extend beyond the motor nerve. SIGNIFICANCE: Muscle cramps correlate with nerve fiber measures in DM 1. PMID- 29175105 TI - Re-evaluating the role of FOXOs in cancer. AB - FOXO transcription factors are negatively regulated by the PI3K-PKB/AKT signaling pathway and have been mainly considered to be tumor suppressors due to their inhibitory effect on cancer cell growth and survival. However, FOXOs can also support tumor development and progression by maintaining cellular homeostasis, facilitating metastasis and inducing therapy resistance. In agreement with these opposing views on the role of FOXOs in cancer, studies using FOXO levels or activity as prognostic markers for cancer patient disease progression and survival came to contradicting results. While it is clear that FOXOs are involved in various aspects of cancer, it is debatable whether FOXOs function as tumor suppressors or supporters, or may be both depending on the context. In this review, we describe the role of FOXOs in signaling pathways and processes relevant to cancer and evaluate recent advances in understanding the role of FOXOs in cancer. Based on recent insights it becomes clear that FOXOs may not be classical tumor suppressors and that targeting FOXO activity might hold promise in cancer therapy. PMID- 29175106 TI - Comprehensive pancancer genomic analysis reveals (RTK)-RAS-RAF-MEK as a key dysregulated pathway in cancer: Its clinical implications. AB - Recent advances in Next Generation Sequencing (NGS) have provided remarkable insights into the genomic characteristics of human cancers that have spurred a revolution in the field of oncology. The mitogen-activated protein kinase pathway (MAPK) and its activating cell receptor, the receptor tyrosine kinases (RTKs), which together encompass the (RTK)-RAS-RAF-MEK-ERK axis, are central to oncogenesis. A pan-cancer genomics analysis presented in this review is made possible by large collaborative projects, including The Cancer Genome Atlas (TCGA), the International Cancer Genome Consortium (ICGC), and others. Landmark studies contributing to these projects have revealed alterations in cell signaling cascades that vary between cancer types and within tumors themselves. We review several of these studies in major tumor types to highlight recent advances in our understanding of the role of (RTK)-RAS-RAF alterations in cancer. Further studies are needed to increase the statistical power to detect clinically relevant low-frequency mutations, in addition to the known (RTK)-RAS-RAF pathway alterations, and to refine the resolution of the genomic landscape that defines these cancer mutations. The (RTK)-RAS-RAF-MEK-ERK mutation status, and their prognostic value, are also examined and correlated with clinical phenotypes. Treatments targeting various components of this pathway are ongoing, and are often effective initially in defined subgroups of patients. However, resistance to these agents can develop through adaptive mechanisms. With our steady increase in understanding the molecular biology of cancer, ongoing evaluation and monitoring through genomic analysis will continue to provide important information to the clinician in the context of treatment selection, response, resistance and outcomes. PMID- 29175108 TI - Nonstructural protein 2A modulates replication and virulence of enterovirus 71. AB - Enterovirus 71 (EV71) can cause hand, foot, and mouth disease in children, and severe infections can induce neurological complications and even death. However, the pathogenesis of EV71 remains unknown. The 2A proteinase (2Apro) of EV71 plays an important role in segmenting the precursor polyprotein during viral replication, inhibiting host protein synthesis, and evading innate immunity. This study was to determine the function of EV71 2Apro in replication and virulence. A chimeric strain (SDLY 107-2A-1) was recombined by replacing 2Apro of a severe strain (SDLY107) with that of a mild strain (SDLY1) based on an infectious cDNA clone. The replication kinetics of the chimeric strain in vitro and in vivo were determined by qRT-PCR, which showed that the chimeric strain replicated slower and generated less viral RNA than the severe strain. The pathological change and viral load of chimeric strain infected mice were intermediate between severe strain infected mice and mild strain infected mice. Cellular cytotoxicity assays revealed that 2Apro was associated with the neurotoxicity of EV71. Histopathological and immunohistochemical assays detected tissue pathological damage in the lungs, muscles, brain, and intestinal tissues. Together, these results suggest that 2Apro modulates replication and virulence of EV71. This provides a theoretical basis for virulence determination of EV71.

PMID- 29175111 TI - Metabolomics Approach to Male Lower Urinary Tract Symptoms: Identification of Possible Biomarkers and Potential Targets for New Treatments. AB - PURPOSE: We identified metabolites using a metabolomics approach and investigated the association between these metabolites and lower urinary tract symptoms. MATERIALS AND METHODS: We used a 24-hour bladder diary and I-PSS (International Prostate Symptom Score) to assess micturition behavior and lower urinary tract symptoms in 58 male patients without apparent neurological disease. Lower urinary tract symptoms were defined as a total I-PSS score of 8 or greater. Patients with a score of 7 or less were placed in the control group. A comprehensive study of plasma metabolites was also performed by capillary electrophoresis time-of-flight mass spectrometry. Metabolites were compared between the lower urinary tract symptoms and control groups using the Mann-Whitney U test. Biomarkers of male lower urinary tract symptoms from the metabolites were analyzed using multivariable logistic regression analysis to determine the OR. RESULTS: Of the 58 men 32 were in the lower urinary tract symptoms group and the remaining 26 were in the control group. The 24-hour bladder diary showed that nocturnal urine volume, 24-hour micturition frequency, nocturnal micturition frequency and the nocturia index were significantly higher in the lower urinary tract symptoms group. Metabolomics analysis identified 60 metabolites from patient plasma. Multivariate analysis revealed that increased glutamate and decreased arginine, asparagine and inosine monophosphate were significantly associated with lower urinary tract symptoms in males. Decreases in citrulline and glutamine could also be associated with male lower urinary tract symptoms. CONCLUSIONS: Male lower urinary tract symptoms may develop due to abnormal metabolic processes in some pathways. Potential new treatments for lower urinary tract symptoms can be developed by identifying changes in the amino acid profiles. PMID- 29175110 TI - Preclinical and clinical studies for transplant tolerance via the mixed chimerism approach. AB - Based upon observations in murine models, we have developed protocols to induce renal allograft tolerance by combined kidney and bone marrow transplantation (CKBMT) in non-human primates (NHP) and in humans. Induction of persistent mixed chimerism has proved to be extremely difficult in major histocompatibility complex (MHC)-mismatched primates, with detectable chimerism typically disappearing within 30-60 days. Nevertheless, in MHC mismatched NHP, long-term immunosuppression-free renal allograft survival has been achieved reproducibly, using a non-myeloablative conditioning approach that has also been successfully extended to human kidney transplant recipients. CKBMT has also been applied to the patients with end stage renal disease with hematologic malignancies. Renal allograft tolerance and long-term remission of myeloma have been achieved by transient mixed or persistent full chimerism. This review summarizes the current status of preclinical and clinical studies for renal and non-renal allograft tolerance induction by CKBMT. Improving the consistency of tolerance induction with less morbidity, extending this approach to deceased donor transplantation and inducing tolerance of non-renal transplants, are critical next steps for bringing this strategy to a wider range of clinical applications. PMID- 29175107 TI - Viruses of archaea: Structural, functional, environmental and evolutionary genomics. AB - Viruses of archaea represent one of the most enigmatic parts of the virosphere. Most of the characterized archaeal viruses infect extremophilic hosts and display remarkable diversity of virion morphotypes, many of which have never been observed among viruses of bacteria or eukaryotes. The uniqueness of the virion morphologies is matched by the distinctiveness of the genomes of these viruses, with ~75% of genes encoding unique proteins, refractory to functional annotation based on sequence analyses. In this review, we summarize the state-of-the-art knowledge on various aspects of archaeal virus genomics. First, we outline how structural and functional genomics efforts provided valuable insights into the functions of viral proteins and revealed intricate details of the archaeal virus host interactions. We then highlight recent metagenomics studies, which provided a glimpse at the diversity of uncultivated viruses associated with the ubiquitous archaea in the oceans, including Thaumarchaeota, Marine Group II Euryarchaeota, and others. These findings, combined with the recent discovery that archaeal viruses mediate a rapid turnover of thaumarchaea in the deep sea ecosystems, illuminate the prominent role of these viruses in the biosphere. Finally, we discuss the origins and evolution of archaeal viruses and emphasize the evolutionary relationships between viruses and non-viral mobile genetic elements. Further exploration of the archaeal virus diversity as well as functional studies on diverse virus-host systems are bound to uncover novel, unexpected facets of the archaeal virome. PMID- 29175112 TI - Chalcones as putative hepatoprotective agents: Preclinical evidence and molecular mechanisms. AB - Chalcones form an important group of natural compounds and flavonoid precursors which are abundant in fruits, vegetables, and edible plants. These compounds have many beneficial properties including anti-inflammatory, anti-microbial, antioxidant, anti-cancer, anti-amyloid, anti-diabetic, anti-obesity, hypolipidemic, and cytoprotective. Chalcone derivatives have protective effects on the liver in nonalcoholic fatty liver disease, alcoholic fatty liver, drug- and toxicant-induced liver injury, and liver cancer through several mechanisms. Chalcones improve adipocytes function and adiponectin secretion. They inhibit triglyceride synthesis, activating factors of hepatic stellate cells and extracellular matrix deposition and also elevate fatty acid oxidation. These effects of chalcones lead to liver injury improvement. In conclusion, chalcones with antioxidant, anti-fibrotic, and anti-inflammatory properties decrease liver injury markers and histological abnormality in liver injury. PMID- 29175113 TI - Molecular adjuvants that modulate regulatory T cell function in vaccination: A critical appraisal. AB - Adjuvants are substances used to enhance the efficacy of vaccines. They influence the magnitude and alter the quality of the adaptive immune response to vaccine antigens by amplifying or modulating different signals involved in the innate immune response. The majority of known adjuvants have been empirically identified. The limited immunogenicity of new vaccine antigens and the need for safer vaccines have increased the importance of identifying single, well-defined adjuvants with known cellular and molecular mechanisms for rational vaccine design. Depletion or functional inhibition of CD4+CD25+FoxP3+ regulatory T cells (Tregs) by molecular adjuvants has become an emergent approach in this field. Different successful results have been obtained for specific vaccines, but there are still unresolved issues such as the risk of autoimmune disease induction, the involvement of cells other than Tregs and optimization for different conditions. This work provides a comprehensive analysis of current approaches to inhibit Tregs with molecular adjuvants for vaccine improvement, highlights the progress being made, and describes ongoing challenges. PMID- 29175114 TI - Phytochemical portfolio and anticancer activity of Murraya koenigii and its primary active component, mahanine. AB - Murraya koenigii, a plant belonging to the Rutaceae family is widely distributed in Eastern-Asia and its medicinal properties are well documented in Ayurveda, the traditional Indian system of medicine. Through systematic research and pharmacological evaluation of different parts of the plant extracts has been shown to possess antiviral, anti-inflammatory, antioxidant, antidiabetic, antidiarrhoeal, antileishmanial, and antitumor activity. In the plant extracts, carbazole alkaloid, mahanine has been identified as the principle bioactive component among several other chemical constituents. Scientific evidence derived not only from in vitro cellular experiments but also from in vivo studies in various cancer models is accumulating for the pronounced anticancer effects of mahanine. The primary objective of this review is to summarize research data on cytotoxic chemical constituents present in different parts of Murraya koenigii and the anticancer activity of mahanine along with the recent understanding on the mechanism of its action in diverse cancer models. The information on its bioavailability and the toxicity generated from the recent studies have also been incorporated in the review. PMID- 29175115 TI - Comparison of Four PD-L1 Immunohistochemical Assays in Lung Cancer. AB - INTRODUCTION: Four different programmed death ligand 1 immunohistochemical assays are approved or in development as companion or complementary diagnostics to different immunotherapeutic agents in lung carcinoma. We sought to determine whether these assays are technically equivalent and whether one antibody can be used on an alternate staining platform. METHODS: Serial sections of tissue microarrays constructed from 368 cases of resected lung cancer were stained for 22C3 and 28-8 on the Dako Link 48 platform (Dako, Carpinteria, Ca) and for SP142 and SP263 on the Ventana Benchmark Ultra platform (Ventana Medical Systems, Tucson, AZ) strictly as per product insert. A protocol was developed to use the 22C3 antibody on the Ventana Benchmark Ultra platform. RESULTS: Differences in mean tumor cell and immune cell staining were observed between the four assays (p < 0.001). Differences between 22C3 and 28-8 were not statistically significant. Concordance of tumor cell scores was good (intraclass correlation coefficient [ICC] = 0.674), particularly when SP142 was excluded as an outlier (ICC = 0.755). The highest concordance was seen between 22C3 and 28-8 (ICC = 0.812). Concordance was poor for immune cell staining (ICC = 0.212). When dichotomized according to clinically relevant cutoffs, pairwise comparisons showed poor to moderate concordance (kappa = 0.196-0.578), with positive percent agreement ranging from 15.1% to 90.0%. The 22C3 antibody performed comparably on the Dako Link 48 platform and the alternate Ventana Benchmark Ultra platform (ICC = 0.921, kappa = 0.897). CONCLUSIONS: Concordance between the four programmed death ligand 1 immunohistochemical assays when performed and scored as intended show that apart from 28-8 and 22C3, they cannot be used interchangeably in clinical practice. A protocol was successfully developed to use 22C3 on an alternate platform, which may help to overcome some barriers to implementation. PMID- 29175116 TI - Current and Emergent Therapy Options for Advanced Squamous Cell Lung Cancer. AB - Squamous cell lung cancer (SqCLC) is a distinct histologic subtype of NSCLC that is challenging to treat because of specific clinicopathologic characteristics, which include older age, advanced disease at diagnosis, comorbid diseases, and the central location of tumors. These characteristics have a bearing on treatment outcomes in advanced SqCLC, resulting in a median survival approximately 30% shorter than for patients with other NSCLC subtypes. In the context of the specific features of SqCLC, we review challenges of treating SqCLC and the current guideline-recommended treatments for advanced (metastatic) SqCLC in different patient subpopulations. We also evaluate recently approved treatment options, including necitumumab, afatinib, nivolumab, pembrolizumab, and atezolizumab; discuss the survival benefits associated with each agent in the advanced SqCLC population; and propose a treatment algorithm incorporating these agents for this challenging-to-treat disease. Lastly, we review the preliminary clinical evidence for immunotherapy agents in development for advanced NSCLC.

PMID- 29175119 TI - Circulating levels of Hsp27 in microvascular complications of diabetes: Prospects as a biomarker of diabetic nephropathy. AB - AIM: Heat shock protein 27 (Hsp27) is a small heat shock protein known to protect the cells from apoptosis under stress. In the present study, we determined the plasma Hsp27 levels in type 2 diabetes subjects without and with microvascular complications- diabetic retinopathy (DRe), diabetic nephropathy (DNe), and diabetic neuropathy (DNu) to understand if it could serve as a marker for these complications. METHODS: This is a hospital-based case-control study with 754 subjects including 247 controls, 195 subjects with diabetes, 123 with DRe, 80 with DNe and 109 with DNu. Plasma Hsp27 levels were measured by ELISA. RESULTS: The mean plasma Hsp27 was higher in the DNe group (631.5+/-355.2) compared to the control (496.55+/-308.54), diabetes (523.41+/-371.01), DRe (494.60+/-391.48) and DNu (455.21+/-319.74) groups with a p-value of 0.018. Receiver operating characteristic (ROC) curve analysis of Hsp27 in DNe group showed an area under the curve (AUC) of 0.617. Spearman correlation analysis shows a positive correlation of plasma Hsp27 with serum creatinine (p=0.053, r-value 0.083). Gender, age and BMI did not affect the plasma Hsp27 levels. CONCLUSION: The plasma Hsp27 levels in the DNe group are higher compared to the control and other complications, thereby it could be explored to be used as a potential biomarker of DNe. PMID- 29175120 TI - Urinary miRNA-377 and miRNA-216a as biomarkers of nephropathy and subclinical atherosclerotic risk in pediatric patients with type 1 diabetes. AB - BACKGROUND: Urinary microRNAs (miRNAs) play a role in the pathogenesis of chronic kidney disease (CKD). AIM: To identify the expression of urinary miR-377 and miR 216a in 50 children and adolescents with type 1 diabetes (T1DM) compared with 50 healthy controls and assess their relation to the degree of albuminuria, glycemic control and carotid intimal thickness (CIMT) as an index of atherosclerosis. METHODS: Diabetic subjects were divided into normoalbuminuric and microalbuminuric groups according to urinary albumin creatinine ration (UACR). Urinary miRNAs were assessed using real time polymerase chain reaction. CIMT was measured using high resolution carotid ultrasound. RESULTS: The expression of urinary miR-377 was significantly higher in patients with microalbumiuria (median, 3.8) compared with 2.65 and 0.98 in normoalbuminic patients and healthy controls, respectively (p<0.05). Urinary miR-216a was significantly lower in all patients with type 1 diabetes and the lowest levels were among the microalbumiuric group. Significant positive correlations were found between urinary miR-377 and HbA1C, UACR and CIMT while urinary miR-216a was negatively correlated to these variables. CONCLUSIONS: Urinary miR-377 and miR-216a can be considered early biomarkers of nephropathy in pediatric type 1 diabetes. Their correlation with CIMT provides insights on the subclinical atherosclerotic process that occurs in diabetic nephropathy.

AB - A+beta+ ketosis prone diabetes (KPD) is associated with slowly progressive autoimmune beta cell destruction. Plasma unmethylated and methylated insulin DNA (biomarkers of ongoing beta cell damage and systemic inflammation, respectively) were elevated in A+beta+ KPD compared to all other KPD subgroups.

AB - The effect of the saturation of fatty acid (FA) in 1,2-dimyristoyl-sn-glycero-3 phosphocoline (DMPC)/FA membrane on the interaction between lipid membrane and amyloid beta monomer was investigated by using the Langmuir monolayer technique. The surface pressure (Pi)-mean molecular area (A) isotherms and fluorescent measurements reveal that DMPC and octadecanoic acid (stearic acid, SA) molecules were somewhat miscible in the mixed membrane, which was maintained to homogeneous gel phase by enhance of the intermolecular hydrophobic interactions because of the all trans acyl chains. On the other hand, DMPC and 9Z,12Z-octadecadienoic acid (linoleic acid, LA) molecules were considered to be well miscible in the mixed membrane, where the membrane partially transferred from gel phase to liquid crystalline phase. The Pi-A isotherms of the monolayers on amyloid beta-peptide (Abeta) solution indicated that Abeta monomers tend to be inserted into the saturated acyl chain region of monolayers at low surface pressure and that the Abeta monomers were then extruded from the monolayer at higher surface pressure. It was observed that behaviors of Abeta monomers at higher surface pressure depended on membrane microstructures. In the DMPC/SA monolayers, Abeta aggregated and then was extruded from monolayers at about 20 mN m-1 of surface pressure irrespective of the SA proportion. On the other hand, in the DMPC/LA monolayers, Abeta, which favors to interact with DMPC, is dispersed in the monolayer even at high surface pressure because DMPC and LA molecules were well miscible in the monolayer.

AB - Herein, we describe a novel enzymatic cycling method to measure nicotinamide mononucleotide (NMN) or nicotinic acid mononucleotide (NaMN), which are precursors of NAD biosynthesis. A gene encoding an NMN adenylyltransferase (NMNAT, EC 2.7.7.1) homologue was identified in Thermus thermophilus HB8. The gene from T. thermophilus (TtNMNAT) was engineered for expression in Escherichia coli and the recombinant enzyme found to be stable, retaining full activity after incubation for 45 min at 70 degrees C. The Km values for NMN and ATP were calculated to be 0.263 and 1.27 mM, respectively, with a Vmax value of 60.3 MUmoL/min/mg. TtNMNAT was successfully applied to the colorimetric NMN or NaMN assays, which employed (i) adenylation of NMN to NAD by TtNMNAT or adenylation of NaMN to deamido-NAD (NaAD) by TtNMNAT followed by amidation of NaAD to NAD by NAD synthetase (NADS, EC 6.3.1.5) and (ii) an NAD cycling reaction using 12alpha hydroxysteroid dehydrogenase (12alpha-HSD, EC 1.1.1.176) and diaphorase (DI, EC 1.6.99.3) to accumulate reduced WST-8. This enzymatic cycling method enabled detection of 0.5 MUM (12.2 nM in the reaction mixture) NMN or NaMN in an automatic clinical analyzer. PMID- 29175124 TI - Enhanced cell-surface display of a heterologous protein using SED1 anchoring system in SED1-disrupted Saccharomyces cerevisiae strain. AB - Yeast displaying enzymes on the cell surface are used for developing whole-cell biocatalysts. High enzyme activity on the cell surface is required in certain applications such as direct ethanol production from lignocellulosic materials. However, the cell surface enzyme activity is limited by several factors, one of which is the protein amount of the yeast cell wall. In this study, we attempted to improve the incorporation capacity of a displayed heterologous enzyme by disrupting a native cell-wall protein. beta-Glucosidase (BGL1) from Aspergillus aculeatus was fused with Saccharomyces cerevisiae Sed1 and displayed on the cell surface of S. cerevisiae BY4741 strain and its SED1 disruptant. Sed1 is one of the most abundant stationary phase yeast cell wall protein. A time course analysis revealed that BGL1 activity of the control strain reached saturation after 48 h of cultivation. In contrast, the BGL1 activity of the SED1 disruptant increased until 72 h of cultivation and was 22% higher than that of the control strain. We also performed relative quantification of cell wall proteins of these strains by nanoscale ultra pressure liquid chromatography electrospray ionization quadrupole time-of-flight tandem mass spectrometry (nano-UPLC-MSE). The amount of the cell wall-associated BGL1 per unit dry cell-weight of the SED1 disruptant was 19% higher than that of the control strain. These results suggested that the incorporation capacity of the cell wall for BGL1 was increased by disruption of SED1. Disruption of SED1 would be a promising approach for improving display efficiency of heterologous protein fused with Sed1.

AB - The emerging mixed contamination of antibiotics and microplastics in greenhouse soil has made the control of antibiotic resistant gene (ARG) transmission a novel challenge. In this work, surfactant sophorolipid was applied to enhance the dissipation of tetracycline (TC) and tet genes in the presence of microplastics in greenhouse soil. During 49days of incubation, soil bacteria and phages were both found to be the crucial reservoirs of ARGs. Meanwhile, microplastic's presence significantly inhibited the dissipation of TC and ARGs in the soil. However, sophorolipid application was proved to outweigh the negative impact caused by microplastic existence, and lead to the highest dissipation of soil TC and ARGs. Significant positive correlation was detected between the dissipation rate of water-soluble and exchangeable TC content and bacteria/phage co-mediated ARG levels. This also held true between the two fractions of soil TC and the ratio of ARG level in the bacteria to that in the phages (BARGs/PARGs). The opposite impacts of microplastic presence and sophorolipid amendment on the TC/ARG dissipation found in this work provides new information for understanding ARG transmission between bacteria and phages in the mixed contaminated greenhouse soil. PMID- 29175126 TI - Immunolocalization of connective tissue growth factor, transforming growth factor beta1 and phosphorylated-SMAD2/3 during the postnatal tooth development and formation of junctional epithelium. AB - Connective tissue growth factor (CTGF) is a downstream mediator of transforming growth factor-beta 1 (TGF-beta1) and TGF-beta1-induced CTGF expression is regulated through SMAD pathway. However, there is no literature showing the expression of TGF-beta1-SMAD2/3-CTGF signaling pathway during postnatal tooth development and the formation of junctional epithelium (JE). Hence, we aimed to analyze the localization of TGF-beta1, CTGF and phosphorylated SMAD2/3 (p SMAD2/3) in the developing postnatal rat molars. Wistar rats were killed at postnatal (PN) 0.5, 3.5, 7, 14 and 21days and the upper jaws were processed for immunohistochemistry. At PN0.5 and PN3.5, weak staining for TGF-beta1 and CTGF was evident in preameloblasts (PA), while moderate to strong staining was seen in odontoblasts (OD), dental papilla (DPL), secretary ameloblasts (SA), preodontoblasts (PO) and polarized odontoblasts (PoO). There was no staining for p-SMAD2/3 in PA, SA, PO and PoO, although strong staining was localized in DPL. OD was initially moderately positive and then negative for p-SMAD2/3. At PN7, intense staining for TGF-beta1 and CTGF was observed in SA, OD, dental pulp (DP) and predentin respectively. p-SMAD2/3 was strongly expressed in DP and moderately expressed in SA and OD. At PN14 and PN21, both reduced enamel epithelium (REE) and JE showed a strong reaction for TGF-beta1 and CTGF. p-SMAD2/3 was intensely and weakly expressed in REE and JE respectively. These data demonstrate that the expression of CTGF, TGF-beta1 and p-SNAD2/3 is tissue-specific and stage specific, and indicate a regulatory role for a TGF-beta1-SMAD2/3-CTGF signaling pathway in amelogenesis, dentinogenesis and formation of JE. PMID- 29175127 TI - Retro-2 and its dihydroquinazolinone derivatives inhibit filovirus infection. AB - Members of the family Filoviridae cause severe, often fatal disease in humans, for which there are no approved vaccines and only a few experimental drugs tested in animal models. Retro-2, a small molecule that inhibits retrograde trafficking of bacterial and plant toxins inside host cells, has been demonstrated to be effective against a range of bacterial and virus pathogens, both in vitro and in animal models. Here, we demonstrated that Retro-2 and its derivatives, Retro-2.1 and compound 25, blocked infection by Ebola virus and Marburg virus in vitro. We show that the derivatives were more potent inhibitors of infection as compared to the parent compound. Pseudotyped virus assays indicated that the compounds affected virus entry into cells while virus particle localization to Niemann-Pick C1-positive compartments showed that they acted at a late step in virus entry. Our work demonstrates a potential for Retro-type drugs to be developed into anti filoviral therapeutics. PMID- 29175128 TI - An evaluation of Chloroquine as a broad-acting antiviral against Hand, Foot and Mouth Disease. AB - A common childhood affliction of viral origin in young children and immunocompromised adults, the Hand, Foot and Mouth Disease (HFMD) has become a significant public health concern in the Asia-Pacific Region. Characterized by the appearance of vesiculopapular rashes on the hands, feet and mouth, the disease is generally mild and self-limiting. In a minority of cases, patients can develop neurological complications that could result in permanent morbidity or even fatality. In the absence of a specific antiviral for treatment, medical care is limited to supportive and symptomatic relief, presenting a need for more research into an effective antiviral to be used in the management of the disease. In this study, we evaluated the efficacy of chloroquine, a FDA-approved lysosomotropic agent, against several serotypes of HFMD-associated enteroviruses, including EV-A71, in reducing infectious virus production. We have also evaluated chloroquine in a murine model of EV-A71 infection to ascertain its antiviral efficacy in vivo. The results suggest that chloroquine could be a broad-acting antiviral effective against HFMD-associated enteroviruses. PMID- 29175129 TI - Vitamin D metabolic loci and vitamin D status in Black and White pregnant women. AB - BACKGROUND: Several candidate genes and genome wide association studies have reported significant associations between vitamin D metabolism genes and 25 hydroxyvitamin D. Few studies have examined these relationships in pregnancy. OBJECTIVE: We evaluated the relationship between maternal allelic variants in three vitamin D metabolism genes and 25-hydroxyvitamin D (25(OH)D) concentration in pregnancy. STUDY DESIGN: In two case-control studies, samples were drawn from women who delivered at Magee Womens Hospital in Pittsburgh, PA from 1999 to 2010 and twelve recruiting sites across the United States from 1959 to 65. For 882 Black and 1796 White pregnant women from these studies, 25(OH)D concentration was measured and single nucleotide polymorphisms (SNPs) were genotyped 50 kilobases up- and down-stream in three genes (VDR, GC, and CYP27B1). Using multivariable linear regression, we estimated the associations between allelic variation of each locus and log-transformed 25(OH)D concentration separately by race and study group. Meta-analysis was used to estimate the association across the four groups for each SNP. RESULTS: Minor alleles of several variants in VDR, GC, and CYP27B1 were associated with differences in log-transformed 25(OH)D concentration compared to the corresponding major alleles [beta, 95% confidence intervals (CI)]. The meta-analysis confirmed the associations for differences in log transformed 25(OH)D by allelic loci for one intron VDR variant [rs2853559 0.08 (0.02, 0.13), p<0.01] and a variant in the GC flanking region [rs13150174: 0.04 (0.02, 0.07), p<0.01], and a GC missense mutation [rs7041 0.05 (0.01, 0.09), p<0.01]. The meta-analysis also revealed possible associations for SNPs in linkage disequilibrium with variants in the VDR 3-prime untranslated region, another GC missense variant (rs4588), and a variant of the 3-prime untranslated region of CYP27B1. CONCLUSION: We observed associations between VDR, GC, and CYP27B1 variants and maternal 25-hydroxyvitamin D concentration. Our results provide additional support for a possible role of genetic variation in vitamin D metabolism genes on vitamin D status during pregnancy. PMID- 29175130 TI - Urinary incontinence is strongly associated with depression in middle-aged and older Korean women: Data from the Korean longitudinal study of ageing. AB - OBJECTIVE: To investigate the relationship between urinary incontinence (UI) and depression in middle-aged and older Korean women. STUDY DESIGN: A total of 1116 participants diagnosed with UI among 7486 respondents were included in this study, using data from a well-established survey that investigated a nationally representative population: the Korean Longitudinal Study of Ageing (KLoSA). Computer-assisted personal interviewing was used to assess the status of UI and depression. Depression was assessed using the 10-item Center for Epidemiological Studies-Depression (CES-D 10) scale. Odds ratios (ORs) and 95% confidence intervals (95% CIs) for depression were adjusted for age, household income level, marital status, education level, working status, smoking behavior, alcohol drinking behavior, exercise level, residence, and accompanying chronic diseases. RESULTS: The proportion of patients with depression was significantly higher among women with UI (9.1%) than among women without UI (6.3%) (P<0.0001). The depression scores became worse with worsening UI symptoms (OR of better vs. same vs. worse, 1.00 vs. 1.51 vs. 2.15, respectively; P for trend=0.0001), with an increased number of days experiencing UI during the prior month during the 2 years of the panel study period (OR of none vs. 1<=days<=10days vs. 10days165 degrees C) using a combination of HNO3 and H2O2 as outlined are proposed as a standard technique for all mammalian tissues, specifically, human tissues and yield greater than 300% higher values than samples digested at 75 degrees C regardless of the acid or acid combinations used. The proposed standardized technique is designed to accurately quantify potential discrepancies in metal loads between cancerous and healthy tissues and applies to numerous tissue studies requiring quick, effective and safe digestions. PMID- 29175138 TI - Polymerization of hexamethylene diisocyanate in solution and a 260.23 m/z [M+H]+ ion in exposed human cells. AB - Hexamethylene diisocyanate (HDI) is an important industrial chemical that can cause asthma, however pathogenic mechanisms remain unclear. Upon entry into the respiratory tract, HDI's N=C=O groups may undergo nucleophilic addition (conjugate) to host molecules (e.g. proteins), or instead react with water (hydrolyze), releasing CO2 and leaving a primary amine in place of the original N=C=O. We hypothesized that (primary amine groups present on) hydrolyzed or partially hydrolyzed HDI may compete with proteins and water as a reaction target for HDI in solution, resulting in polymers that could be identified and characterized using LC-MS and LC-MS/MS. Analysis of the reaction products formed when HDI was mixed with a pH buffered, isotonic, protein containing solution identified multiple [M+H]+ ions with m/z's and collision-induced dissociation (CID) fragmentation patterns consistent with those expected for dimers (259.25/285.23 m/z), and trimers (401.36/427.35 m/z) of partially hydrolyzed HDI (e.g. ureas/oligoureas). Human peripheral blood mononuclear cells (PBMCs) and monocyte-like U937, but not airway epithelial NCI-H292 cell lines cultured with these HDI ureas contained a novel 260.23 m/z [M+H]+ ion. LC-MS/MS analysis of the 260.23 m/z [M+H]+ ion suggest the formula C13H29N3O2 and a structure containing partially hydrolyzed HDI, however definitive characterization will require further orthogonal analyses. PMID- 29175139 TI - In vitro-in vivo correlations for nicotine transdermal delivery systems evaluated by both in vitro skin permeation (IVPT) and in vivo serum pharmacokinetics under the influence of transient heat application. AB - The in vitro permeation test (IVPT) has been widely used to characterize the bioavailability (BA) of compounds applied on the skin. In this study, we performed IVPT studies using excised human skin (in vitro) and harmonized in vivo human serum pharmacokinetic (PK) studies to evaluate the potential in vitro-in vivo correlation (IVIVC) of nicotine BA from two, matrix-type, nicotine transdermal delivery systems (TDS). The study designs used for both in vitro and in vivo studies included 1h of transient heat (42+/-2 degrees C) application during early or late time periods post-dosing. The goal was to evaluate whether any IVIVC observed would be evident even under conditions of heat exposure, in order to investigate further whether IVPT may have the potential to serve as a possible surrogate method to evaluate the in vivo effects of heat on the bioavailability of a drug delivered from a TDS. The study results have demonstrated that the BA of nicotine characterized by the IVPT studies correlated with and was predictive of the in vivo BA of nicotine from the respective TDS, evaluated under the matched study designs and conditions. The comparisons of single parameters such as steady-state concentration, heat-induced increase in partial AUCs and post-treatment residual content of nicotine in TDS from the in vitro and in vivo data sets showed no significant differences (p>=0.05). In addition, a good point-to-point IVIVC (Level A correlation) for the entire study duration was achieved by predicting in vivo concentrations of nicotine using two approaches: Approach I requiring only an in vitro data set and Approach II involving deconvolution and convolution steps. The results of our work suggest that a well designed IVPT study with adequate controls can be a useful tool to evaluate the relative effects of heat on the BA of nicotine from TDS with different formulations. PMID- 29175140 TI - Comparison of in vivo targeting ability between cRGD and collagen-targeting peptide conjugated nano-carriers for atherosclerosis. AB - Atherosclerosis plaque is a major cause of cardiovascular diseases across the globe and a silent killer. There are no physical symptoms of the disease in its early stage and current diagnostic techniques cannot detect the small plaques effectively or safely. Plaques formed in blood vessels can cause serious clinical problems such as impaired blood flow or sudden death, regardless of their size. Thus, detecting early stage of plaques is especially more important to effectively reduce the risk of atherosclerosis. Nanoparticle based delivery systems are recognized as a promising option to fight against this disease, and various targeting ligands are typically used to improve their efficiency. So, the choice of appropriate targeting ligand is a crucial factor for optimal targeting efficiency. cRGD peptide and collagen IV targeting peptide, which binds with the alphavbeta3 integrin overexpressed in the neovasculature of the plaque and collagen type IV present in the plaque, respectively, are frequently used for the targeting of nanoparticles. However, at present no study has directly compared these two peptides. Therefore, in this study, we have prepared cRGD or collagen IV targeting (Col IV-tg-) peptide conjugated and iron oxide nanoparticle (IONP) loaded Pluronic based nano-carriers for systemic comparison of their targeting ability towards in vivo atherosclerotic plaque in Apolipoprotein E deficient (Apo E-/-) mouse model. Nano-carriers with similar size, surface charge, and IONP loading content but with different targeting ligands were analyzed through in vitro and in vivo experiments. Near infrared fluorescence imaging and magnetic resonance imaging techniques as well as Prussian blue staining were used to compare the accumulation of different ligand conjugated nano-caariers in the aorta of atherosclerotic mice. Our results indicate that cRGD based targeting is more efficient than Col IV-tg-peptide in the early stage of atherosclerosis. PMID- 29175141 TI - Large neutral amino acid supplementation as an alternative to the phenylalanine restricted diet in adults with phenylketonuria: evidence from adult Pah-enu2 mice. AB - Phenylketonuria treatment mainly consists of a phenylalanine-restricted diet but still results in suboptimal neuropsychological outcome, which is at least partly based on cerebral monoamine deficiencies, while, after childhood, treatment compliance decreases. Supplementation of large neutral amino acids (LNAAs) was previously demonstrated in young phenylketonuria mice to target all three biochemical disturbances underlying brain dysfunction in phenylketonuria. However, both its potential in adult phenylketonuria and the comparison with the phenylalanine-restricted diet remain to be established. To this purpose, several LNAA supplements were compared with a severe phenylalanine-restricted diet with respect to brain monoamine and amino acid concentrations in adult C57Bl/6 Pah enu2 mice. Adult phenylketonuria mice received a phenylalanine-restricted diet, unrestricted diet supplemented with several combinations of LNAAs or AIN-93M control diet for 6 weeks. In addition, adult wild-type mice on AIN-93M diet served as controls. The severe phenylalanine-restricted diet in adult phenylketonuria mice significantly reduced plasma and brain phenylalanine and restored brain monoamine concentrations, while brain concentrations of most nonphenylalanine LNAAs remained subnormal. Supplementation of eight LNAAs was similarly effective as the severe phenylalanine-restricted diet to restore brain monoamines, while brain and plasma phenylalanine concentrations remained markedly elevated. These results provide biochemical support for the effectiveness of the severe phenylalanine-restricted diet and showed the possibilities of LNAA supplementation being equally effective to restore brain monoamines in adult phenylketonuria mice. Therefore, LNAA supplementation is a promising alternative treatment to phenylalanine restriction in adult phenylketonuria patients to further optimize neuropsychological functioning. PMID- 29175142 TI - Flaxseed oil rich in omega-3 protects aorta against inflammation and endoplasmic reticulum stress partially mediated by GPR120 receptor in obese, diabetic and dyslipidemic mice models. AB - The "first hit" to atherogenesis is driven by toll-like receptor 4, endoplasmic reticulum stress and ultimately metabolic dysfunction. In this study, we hypothesized that a flaxseed oil-enriched diet (FS) abolishes these inflammatory signaling pathway and restore metabolic homeostasis by activating the fatty acid receptor GPR120 in aorta of obese mice. Glucose homeostasis was assessed by GTT and ITT; lipidomics was performed using a Hybrid Ion Trap-Orbitrap Mass Spectrometer; serum lipids were measured using colorimetric assays; GPR120 and infiltrating macrophages were analyzed by immunofluorescence; protein immunoprecipitation and gene expression were evaluated by Western blot and RT PCR, respectively. There were no differences in body weight and food intake between the groups from both strains (Swiss and LDLr-KO mice). GTT and cholesterol levels were improved by FS in both mice models. Lipidomics showed an increase in omega3 (C18:3) content, meanwhile stearic acid (C18:0) was not detected in endothelial tissue in response to FS. Moreover, FS markedly decreased pro-inflammatory (IL-1beta, TNF-alpha, pIkappaBalpha, pIKKbeta) and unfolded protein response markers (ATF6 and GRP78) in aorta. In Swiss mice, GPR120 was partially involved in the omega3-mediated anti-inflammatory actions, disrupting TLR4 pathway, but not in LDLr-KO mice. Partial replacement of dietary saturated by unsaturated omega3 fatty acids contributes to inhibition of cardiovascular risk markers, pro-inflammatory cytokines and ER stress sensors and effectors in the aorta. However, downregulation of inflammation is not mediated by arterial GPR120 activation.

AB - The photonuclear production of no-carrier-added (NCA) 47Sc from solid NatTiO2 and the subsequent chemical processing and purification have been developed. Scandium 47 was produced by the 48Ti(gamma,p)47Sc reaction with Bremsstrahlung photons produced from the braking of electrons in a high-Z (W or Ta) convertor. Production yields were simulated with the PHITS code (Particle and Heavy Ion Transport-code System) and compared to experimental results. Irradiated TiO2 targets were dissolved in fuming H2SO4 in the presence of Na2SO4 and 47Sc was purified using the commercially available Eichrom DGA resin. Typical 47Sc recovery yields were >90% with excellent specific activity for small batches (<185 MBq batches). PMID- 29175144 TI - Association between Helicobacter pylori infection and cognitive impairment in the elderly. AB - BACKGROUND/PURPOSE: Helicobacter pylori (H. pylori) infection has been positively associated with cognitive impairment. However, previous studies have shown inconsistent findings. METHODS: This cross-sectional study included 587 elderly participants (age ? 65) from the annual elderly health checkup program at the National Taiwan University Hospital from 2011 to 2013. Both global and domain specific cognition were assessed using various neuropsychiatric tests. Multivariable linear regression and logistic regression models were utilized to assess the association between the serum H. pylori IgG level and cognitive impairment. RESULTS: Compared with the lowest quartile of H. pylori IgG (Q1), the highest quartile (Q4) was associated with lower scores on verbal fluency vegetables (beta = -0.24), domain-specific attention [digit span-forward: beta = 0.19; odds ratio (OR) = 1.83, 95% confidence interval (CI) = 1.03-3.24], and attention factors (beta = -0.20; OR= 2.67, 95% CI = 1.51-4.73). No significant association was observed for global cognition. Stratified analyses revealed that, among men, the highest quartile of serum H. pylori IgG (Q4) was associated with impaired scores on verbal fluency-vegetables (beta = -0.38; OR = 3.01, 95% CI = 1.42-6.38). CONCLUSION: Our findings disclosed a positive association between serum H. pylori level and cognitive impairment, which provides important information for the primary prevention of cognitive impairment through the eradication of H. pylori.

AB - BACKGROUND: HER2-targeted treatments have improved outcomes in patients with HER2 positive breast cancer in the neoadjuvant, adjuvant, and metastatic settings; however, some patients remain at risk of relapse or death for many years after treatment of early-stage disease. Therefore, new strategies are needed. We did a phase 3 trial to assess a neoadjuvant regimen for HER2-positive breast cancer that replaces traditional systemic chemotherapy with targeted treatment. METHODS: We did a randomised, open-label phase 3 KRISTINE trial in 68 Translational Research In Oncology centres (hospitals and specialty cancer centres in Asia, Europe, USA, and Canada). Eligible participants were aged 18 years or older with centrally confirmed HER2-positive stage II-III operable breast cancer (>2 cm tumour size), an Eastern Cooperative Oncology Group performance status of 0-1, and a baseline left ventricular ejection fraction of at least 55% (by echocardiogram or multiple-gated acquisition scan). We randomly assigned participants (1:1) to receive either trastuzumab emtansine plus pertuzumab or docetaxel, carboplatin, and trastuzumab plus pertuzumab. We did the randomisation via an interactive response system under a permuted block randomisation scheme (block size of four), stratified by hormone receptor status, stage at diagnosis, and geographical location. Patients received six cycles (every 3 weeks) of neoadjuvant trastuzumab emtansine plus pertuzumab (trastuzumab emtansine 3.6 mg/kg; pertuzumab 840 mg loading dose, 420 mg maintenance doses) or docetaxel, carboplatin, and trastuzumab plus pertuzumab (docetaxel 75 mg/m2; carboplatin area under the concentration-time curve 6 mg/mL * min; trastuzumab 8 mg/kg loading dose, 6 mg/kg maintenance doses) plus pertuzumab [same dosing as in the other group]). All treatments were administered intravenously. The primary objective was to compare the number of patients who achieved a pathological complete response (ypT0/is, ypN0), between groups in the intention-to-treat population (two-sided assessment), based on local evaluation of tumour samples taken at breast cancer surgery done between 14 days and 6 weeks after completion of neoadjuvant therapy. Safety was analysed in patients who received at least one dose of study medication. This trial is registered with ClinicalTrials.gov, number NCT02131064, and follow-up of the adjuvant phase is ongoing. FINDINGS: Between June 25, 2014, and June 15, 2015, we randomly assigned 444 patients to neoadjuvant treatment with trastuzumab emtansine plus pertuzumab (n=223) or docetaxel, carboplatin, and trastuzumab plus pertuzumab (n=221). A pathological complete response was achieved by 99 (44.4%) of 223 patients in the trastuzumab emtansine plus pertuzumab group and 123 (55.7%) of 221 patients in the docetaxel, carboplatin, and trastuzumab plus pertuzumab group (absolute difference -11.3 percentage points, 95% CI -20.5 to -2.0; p=0.016). During neoadjuvant treatment, compared with patients receiving docetaxel, carboplatin, and trastuzumab plus pertuzumab, fewer patients receiving trastuzumab emtansine plus pertuzumab had a grade 3-4 adverse event (29 [13%] of 223 vs 141 [64%] of 219) or a serious adverse event (11 [5%] of 223 vs 63 [29%] of 219). The most common grade 3-4 adverse events in the trastuzumab emtansine plus pertuzumab group were decreased platelet count (three [1%] of 223 patients vs 11 [5%] of 219 with docetaxel, carboplatin, and trastuzumab plus pertuzumab), fatigue (three [1%] vs seven [3%]), alanine aminotransferase increase (three [1%] vs four [2%]), and hypokalaemia (three [1%] vs five [2%]). The most common grade 3-4 adverse events in the docetaxel, carboplatin, and trastuzumab plus pertuzumab group were neutropenia (55 [25%] of 219 vs one [<1%] of 223 with trastuzumab emtansine plus pertuzumab), diarrhoea (33 [15%] vs 2 [<1%]), and febrile neutropenia (33 [15%] vs 0). No deaths were reported during neoadjuvant treatment. INTERPRETATION: Traditional neoadjuvant systemic chemotherapy plus dual HER2-targeted blockade (docetaxel, carboplatin, and trastuzumab plus pertuzumab) resulted in significantly more patients achieving a pathological complete response than HER2 targeted chemotherapy plus HER2-targeted blockade (trastuzumab emtansine plus pertuzumab); however, numerically more grade 3-4 and serious adverse events occurred in the chemotherapy plus trastuzumab and pertuzumab group. Further efforts to improve the efficacy of chemotherapy without imparting more toxicity are warranted. FUNDING: F Hoffmann-La Roche and Genentech.

AB - Accumulated evidence displayed that transplantation of stem cells may be a promising approach for the treatment of neurological disorders. However, the underlying mechanisms remain to be well elucidated. Moreover, some investigators cannot reproduce similar results as the previous. The present results showed that transplantation of fresh human umbilical cord blood mononuclear cells (cbMNCs) attenuated ischemic damage in middle cerebral artery occlusion (MCAO) rats, accompanied with improvement of neurologic deficits, learning and memory function. The increase in neovascularization and related molecules such as vascular endothelial growth factor (VEGF), Angiopoietin-1 (Ang-1) and endothelium specific receptor tyrosine kinase 2 (Tie-2) in the injured brain was observed in cbMNCs-treated rats. Moreover, nuclear factor-kappaB (NF-kappaB) activation and nucleotide binding and oligomerization domain-like receptor family pyrin domain containing 3 (NLRP3) inflammasome were also inhibited by the cells graft, resulting in reduction in cleaved caspase-1 and mature interleukin-1beta (IL 1beta) content. These results suggested that the protective actions of the cells on the cerebral ischemia may be related to inhibition of NF-kappaB pathway and NLRP3 inflammasome.

AB - Short-term synaptic plasticity (SSP) is a basic mechanism for temporal processing of neural information in synaptic transmission. Facilitation, the fastest component of SSP, has been extensively investigated with regard to Ca2+ signaling and other relevant substances. However, systematic analyses on the slower components of SSP, originated by Magleby and Zengel, have remained stagnant for decades, as few chemicals directly modifying these slower components have been identified. In combination with refined experimental protocols designed to study the stimulation frequency-dependence of SSP and botulinum neurotoxins A and C (BoNT-A and BoNT-C), we investigated SSP of frog neuromuscular transmission to clarify the roles of synaptosomal-associated protein of 25 kDa (SNAP-25) and syntaxin, SNARE proteins exclusively participating in vesicular events including docking, priming and exocytosis. We found that BoNT-A treatment eliminated slow potentiation, and BoNT-C poisoning abolished intermediate augmentation, two components of SSP. Fast facilitation was maintained after double poisoning with BoNT-A and -C, but the postsynaptic response became biphasic. A novel depression, termed repression, emerged by double poisoning. Repression was different from depletion because it developed even at a low-frequency stimulation of 1 Hz. We conclude that SNAP-25 and syntaxin not only play roles as cooperative exocytotic machinery, but also have roles in SSP.

AB - We have earlier demonstrated that a Status Epilepticus (SE) during CNS development has long-lasting effects on cholinergic neurotransmission, detectable in vitro and in vivo. In this work, we aimed to localize changes in temporal (T) vs septal (S) hippocampus and to correlate adult CA3 interictal epileptiform discharge (IED) frequency changes to those of Ripples (R) and Fast Ripples (FR) of the High-Frequency Oscillations (HFOs). Spontaneous IEDs were induced by bathing slices in Mg2+-free ACSF or in 4-Aminopyridine (4-AP, 50 uM) and data were analyzed separately for each model. IED frequencies were similar in same origin normal (N) slices across models, but differed in SE slices, being lower in Mg2+-free ACSF than in 4-AP, suggesting a post-SE long-term increase in a K+ conductance. Rs and FRs detected within IEDs had generally higher power in 4-AP than in Mg2+-free ACSF; FR/R ratio was the highest in T-SE slices in 4-AP and similar in all other slice groups. Carbachol or eserine increased IED rates universally, but had region- and conditioning-specific effects on HFOs, suggesting that IED frequency and HFOs represent possibly independent indices of excitability. The muscarinic antagonist atropine depressed IED rates with increasing effectiveness in S slices post-SE in both models. In conclusion, the long-term effects of an immature SE are region-specific within the hippocampus, affect differently synchronizing components like the IED frequency and HFOs and may shape neurotransmitter effects (ACh) on neuronal networks, thus affecting seizure threshold and information processing, especially in behavioral conditions of rising extracellular ACh levels. PMID- 29175156 TI - IL-33/ST2 Pathway as a Rational Therapeutic Target for CNS Diseases. AB - Interleukin (IL)-33 is a member of the interleukin-1 cytokine family that is produced by many different types of tissues including the central nervous system (CNS). IL-33 mediates its effects via its heterodimeric receptor complex, comprised of ST2 and the IL-1 receptor accessory protein (IL-1RAcp). As a pleiotropic nuclear cytokine, IL-33 is a crucial factor in the development of cardiovascular diseases, allergic diseases, infectious diseases, and autoimmune diseases. Recently, accumulated evidence shows that the IL-33/ST2 axis plays a crucial and diverse role in the pathogenesis of CNS diseases, including neurodegenerative diseases, cerebrovascular diseases, infectious diseases, traumatic CNS injury, chronic pain, etc. In this review, we discuss the recent findings in the cellular signaling of IL-33 and advancement of the role of IL-33 in several CNS diseases, as well as its therapeutic potential for the treatment of those diseases. PMID- 29175155 TI - Neuroanatomical Distribution of DEK Protein in Corticolimbic Circuits Associated with Learning and Memory in Adult Male and Female Mice. AB - DEK, a chromatin-remodeling gene expressed in most human tissues, is known for its role in cancer biology and autoimmune diseases. DEK depletion in vitro reduces cellular proliferation, induces DNA damage subsequently leading to apoptosis, and down-regulates canonical Wnt/beta-catenin signaling, a molecular pathway essential for learning and memory. Despite a recognized role in cancer (non-neuronal) cells, DEK expression and function is not well characterized in the central nervous system. We conducted a gene ontology analysis (ToppGene), using a cancer database to identify genes associated with DEK deficiency, which pinpointed several genes associated with cognitive-related diseases (i.e., Alzheimer's disease, presenile dementia). Based on this information, we examined DEK expression in corticolimbic structures associated with learning and memory in adult male and female mice using immunohistochemistry. DEK was expressed throughout the brain in both sexes, including the medial prefrontal cortex (prelimbic, infralimbic and dorsal peduncular). DEK was also abundant in all amygdalar subdivisions (basolateral, central and medial) and in the hippocampus including the CA1, CA2, CA3, dentate gyrus (DG), ventral subiculum and entorhinal cortex. Of note, compared to males, females had significantly higher DEK immunoreactivity in the CA1, indicating a sex difference in this region. DEK was co-expressed with neuronal and microglial markers in the CA1 and DG, whereas only a small percentage of DEK cells were in apposition to astrocytes in these areas. Given the reported inverse cellular and molecular profiles (e.g., cell survival, Wnt pathway) between cancer and Alzheimer's disease, these findings suggest a potentially important role of DEK in cognition. PMID- 29175159 TI - Hierarchical microcrack model for materials exemplified at enamel. AB - OBJECTIVE: This article investigates the mechanical properties of a material with hierarchically arranged microcracks. METHODS: Hierarchically structured biomaterials such as enamel exhibit superior mechanical properties as being stiff and damage tolerant at the same time. The common mechanical explanation for this behavior is based on the hierarchically structured arrangement of hard minerals and soft organics and their cooperative deformation mechanisms. In situ mechanical experiments with mm-sized bovine enamel bending bars an scanning electron microscope reveal that enamel is able to withstand mechanical loading even if it contains microcracks on different lengths scales. To clarify this issue an analytical hierarchical microcrack model of non-interacting cracks is presented. RESULTS AND SIGNIFICANCE: The model predicts a decrease of the elastic modulus and the fracture strength with increasing levels of hierarchy. The fracture strain on the other hand may decrease or increase with the number of hierarchical levels, depending on the microcrack density. This simple hierarchical microcrack model is able to explain already published experiments with focused ion beam prepared MUm-sized enamel cantilevers on different hierarchical levels. In addition it is shown that microcracking during loading in hierarchical materials may lead to substantial pseudoplastic behavior. PMID- 29175157 TI - Mapping the Structural Determinants Required for AAVrh.10 Transport across the Blood-Brain Barrier. AB - Effective gene delivery to the CNS by intravenously administered adeno-associated virus (AAV) vectors requires crossing the blood-brain barrier (BBB). To achieve therapeutic CNS transgene expression, high systemic vector doses are often required, which poses challenges such as scale-up costs and dose-dependent hepatotoxicity. To improve the specificity and efficiency of CNS gene transfer, a better understanding of the structural features that enable AAV transit across the BBB is needed. We generated a combinatorial domain swap library using AAV1, a serotype that does not traverse the vasculature, and AAVrh.10, which crosses the BBB in mice. We then screened individual variants by phylogenetic and structural analyses and subsequently conducted systemic characterization in mice. Using this approach, we identified key clusters of residues on the AAVrh.10 capsid that enabled transport across the brain vasculature and widespread neuronal transduction in mice. Through rational design, we mapped a minimal footprint from AAVrh.10, which, when grafted onto AAV1, confers the aforementioned CNS phenotype while diminishing vascular and hepatic transduction through an unknown mechanism. Functional mapping of this capsid surface footprint provides a roadmap for engineering synthetic AAV capsids for efficient CNS gene transfer with an improved safety profile. PMID- 29175160 TI - The effect of chewing simulation on surface roughness of resin composite when opposed by zirconia ceramic and lithium disilicate ceramic. AB - OBJECTIVE: To assess the change in surface roughness of nanohybrid resin composite (Tetric EvoCeram) after antagonist wear against monolithic zirconia and lithium disilicate ceramics through a simulated chewing test using a three dimensional (3D) profilometer. METHODS: A total of 40 Tetric EvoCeramTM resin composite specimens against either a LavaTM Plus zirconia antagonist (n=20) or IPS e.max Press lithium disilicate antagonist (n=20) were prepared for the study. The surface roughness profiles of each resin composite before and after an in vitro simulated chewing test were analysed using a 3D profilometer and Talymap software. After the simulated chewing, the surface profiles of representative Tetric EvoCeram specimens from each group were analysed using scanning electron microscopy. Independent t-test and paired t-test were used for statistical analysis. RESULTS: For both lithium disilicate and zirconia groups, all surface roughness parameters (Ra, Rt, Sa, Sq,) of Tetric EvoCeram were significantly higher post-chewing compared to pre-chewing (p<0.05); the post-chewing surface roughness parameters of Tetric EvoCeram for the lithium disilicate group were significantly higher (p<0.05) than in the zirconia group. SIGNIFICANCE: This chewing simulation test showed that Tetric EvoCeram composites exhibited a rougher surface when opposing lithium disilicate ceramic compared to opposing zirconia ceramic. PMID- 29175161 TI - Induction of DNA double-strand breaks in human gingival fibroblasts by eluates from titanium dioxide modified glass ionomer cements. AB - OBJECTIVES: (1) To investigate the genotoxicity of a glass ionomer cement (GIC) and GIC incorporated with titanium dioxide nanopoarticle (TiO2NPs) and with microparticle (TiO2MPs) on DNA double-strand breaks of human gingival fibroblast cells (HGFs). (2) To compare the genotoxic differences between GIC and two modified cements. METHODS: TiO2NPsGIC and TiO2MPsGIC were prepared by adding 10% w/w of TiO2NPs and TiO2MPs to the GIC powder and hand-mixed followed the manufacturer instruction. Dulbecco's Minimum Essential Medium (DMEM) was used as a culture medium for HGFs and eluate preparation. Eluates from all groups were collected for XTT cell viability assay to obtain EC50 values. gamma-H2AX immunofluorescence assay was performed to detect DNA double-strand breaks (DSBs) of HGFs. RESULTS: EC50 values were from 38% to 60% and eluate concentrations at 20% and 5% were selected for gamma-H2AX immunofluorescence assay. At both concentrations, HGFs exposed to eluates from all cements groups had fewer mean foci per cell and higher percentage of free foci cells than H2O2 (p<0.05). At 20% concentration, cells exposed to eluates from both TiO2NPsGIC and TiO2MPsGIC groups had fewer mean foci per cell and higher percentage of free foci cell than GIC and culture medium (p<0.05). SIGNIFICANCE: Neither GIC nor 10% TiO2-modified GICs had a genotoxic effect on HGFs. Both TiO2NPsGIC and TiO2MPsGIC demonstrated less genotoxic effect than GIC. When comparing between the two modified cements, there was no genotoxic difference between the modified cements from different particle sizes (nanoparticle and micro-particle) of TiO2. PMID- 29175158 TI - Multi-modal Potentiation of Oncolytic Virotherapy by Vanadium Compounds. AB - Oncolytic viruses (OV) are an emerging class of anticancer bio-therapeutics that induce antitumor immunity through selective replication in tumor cells. However, the efficacy of OVs as single agents remains limited. We introduce a strategy that boosts the therapeutic efficacy of OVs by combining their activity with immuno-modulating, small molecule protein tyrosine phosphatase inhibitors. We report that vanadium-based phosphatase inhibitors enhance OV infection in vitro and ex vivo, in resistant tumor cell lines. Furthermore, vanadium compounds increase antitumor efficacy in combination with OV in several syngeneic tumor models, leading to systemic and durable responses, even in models otherwise refractory to OV and drug alone. Mechanistically, this involves subverting the antiviral type I IFN response toward a death-inducing and pro-inflammatory type II IFN response, leading to improved OV spread, increased bystander killing of cancer cells, and enhanced antitumor immune stimulation. Overall, we showcase a new ability of vanadium compounds to simultaneously maximize viral oncolysis and systemic anticancer immunity, offering new avenues for the development of improved immunotherapy strategies. PMID- 29175162 TI - A pH-stable, detergent and chelator resistant type I pullulanase from Bacillus pseudofirmus 703 with high catalytic efficiency. AB - Pullulanase with high catalytic efficiency has attracted great attention from both the academic and industrial communities for its wide application in cold starch hydrolysis. A novel pullulanase gene pul703 was cloned from a mesophilic bacteria Bacillus pseudofirmus 703. Pul703 was characterized to be a type I pullulanase with maximal activity at 45 degrees C and good low-temperature stability, more than 70% of activity was detected after incubation at 25-35 degrees C for 72h. Pul703 obtained the maximal activity around pH 7.0-8.0, and was highly active and stable over a wide pH range of 5.5-9.5, more than 80% of activity was retained after 12h incubation in these pHs. Pul703 was EDTA resistant and detergent-tolerant, with a relative activity of 100, 99, and 114.8% at the presence of 10mM EDTA, 10% of Triton X-100 and Tween 20, respectively. Pul703 can efficiently hydrolyze pullulan with a specific activity of 270U/mg, which was higher than all reported type I pullulanases. In addition, Pul703 can act synergistically with alpha-amylase BLA to efficiently hydrolyze amylopectin. These results suggested that Pul703 was a good candidate for cold starch hydrolysis. PMID- 29175163 TI - Production and characterization of a novel acidophilic and thermostable xylanase from Thermoascus aurantiacu. AB - The thermostable fungus, Thermoascus aurantiacus M-2, which produces a novel acidophilic and thermostable xylanase was isolated and identified based on its morphology and comparison of the internal transcribed spacer rDNA gene sequence. The culture conditions and components of medium were optimized for T. aurantiacus M-2 to produce xylanase. T. aurantiacus M-2 produced xylanase at a maximum level of 39.07 U/mL after 8-d fermentation at 45 degrees C in the optimized medium. The purified xylanase produced by T. aurantiacus M-2 has a relative molecular mass of approximately 31.0 kD. The characteristics of purified xylanase were investigated. The purified T. aurantiacus xylanase exhibited maximum activity at 75 degrees C and pH 5.0, and it was stable after treatment at a pH range from 2.0 to 10.0 or a temperature range from 30 degrees C to 80 degrees C for 2-h. Mn2+ and Ag+ enhanced xylanase activity to 120.0% and 119.6%, respectively, while Mn2+ had the highest inhibition ratio, with a residual activity of 20.7%. This study provided a foundation for scaled-up production and application of xylanase. PMID- 29175164 TI - Antibacterial activity of a new lectin isolated from the marine sponge Chondrilla caribensis. AB - A new lectin from the marine sponge Chondrilla caribensis (CCL) was isolated by affinity chromatography in Sepharose 6B media. CCL is a homotetrameric protein formed by subunits of 15,445 +/-2Da. The lectin showed affinity for disaccharides containing galactose and mucin. Mass spectrometric analysis revealed about 50% of amino acid sequence of CCL, which showed similarity with a lectin isolated from Aplysina lactuca. Secondary structure consisted of 10% alpha-helix, 74% beta sheet/beta-turn and 16% coil, and this profile was unaltered in a broad range of pH and temperatures. CCL agglutinated Staphylococcus aureus, S epidermidis and Escherichia coli, and it was able to reduce biofilm biomass, but showed no inhibition of planktonic growth of these bacteria. CCL activity was inhibited by alpha-lactose, indicating that Carbohydrate Recognition Domain (CRD) of the lectin was involved in antibiofilm activity. PMID- 29175165 TI - Functional properties of chickpea protein isolates dried by refractance window drying. AB - In the present study, the effect of Refractance Window (RW) drying on the functional properties of chickpea protein isolates was investigated and compared to freeze drying at different pH levels. The functional properties investigated were protein solubility, water and oil holding capacity, emulsifying properties, foaming properties, flocculation and coalescence indices and textural properties. The solubility, oil holding capacity and foam stability of the freeze dried protein isolates were determined to be higher than the RW dried samples. On the other hand, the RW dried samples had better water holding capacity and emulsion stability compared to the freeze dried protein isolates. The emulsion activity index, flocculation and coalescence indices of the chickpea protein isolates prepared by different drying techniques showed different tendencies depending on the pH level. Freeze dried protein isolates exhibited higher gelation ability than RW dried samples according to the texture profile analysis. This study clearly showed that the drying technique used in the preparation of protein isolates can affect their functional properties. PMID- 29175166 TI - Extraction and physicochemical characterization of chitin and chitosan from Zophobas morio larvae in varying sodium hydroxide concentration. AB - Large amount of sodium hydroxide (NaOH) is consumed to remove the protein content in chitin biomass during deproteinization. However, excessive NaOH concentration used might lead to the reduction of cost effectiveness during chitin extraction. Hence, the present study aimed to extract and evaluate the physicochemical properties of chitin and chitosan isolated from superworm (Zophobas morio) larvae using 0.5M-2.0M of NaOH. The extracted chitin and chitosan were subjected to Fourier Transform Infrared Spectroscopy (FT-IR), elemental analysis, Scanning Electron Microscope (SEM), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC) and X-ray Diffraction (XRD). The 0.5M NaOH treatment resulted in the highest yield of chitin (5.43%), but produced the lowest yield (65.84%) of chitosan. The extracted chitin samples had relatively high degree of acetylation (DA) (82.39%-101.39%). Both chitin and chitosan showed smooth surface with tiny pores. The extracted chitin samples were confirmed as alpha-chitin based on the FT-IR and TGA. The chitin samples were amorphous with low degree of crystallinity. From TGA, the Chitosan 3 extracted was partially deacetylated. Both DPPH radical scavenging and ferric-chelating assay showed positive correlation with DD of chitosan isolates. However, the chitosan isolates were not fully dissolved, resulting in lower radical scavenging and ferric-chelating ability compared to commercial chitosan. PMID- 29175167 TI - A dual-function chymotrypsin-like serine protease with plasminogen activation and fibrinolytic activities from the GRAS fungus, Neurospora sitophila. AB - In this study, we have isolated and characterized a fibrinolytic enzyme from the GRAS (Generally Recognized as Safe) fungus, Neurospora sitophila. The enzyme was purified by fractional ammonium sulfate precipitation, hydrophobic interaction, ion exchange and gel filtration chromatography to 45.2 fold with a specific activity of 415.6U/mg protein. The native molecular mass of the enzyme was 49kDa, while the denatured molecular mass was 30kDa and 17.5kDa, indicating that the enzyme was a hetero-dimer. It was optimally active at 50 degrees C and pH 7.4 and stable at human physiological temperature and pH. It was found to be a chymotrypsin-like serine protease which cleaved the synthetic chromogenic substrate, N-Succinyl-Ala-Ala-Pro-Phe-pNA for which the apparent Km and Vmax values were 0.24mM and 4.17*10-5mM/s, respectively. The enzyme hydrolyzed all the chains of fibrinogen by cleaving alpha chain first, followed by beta chain and then gamma chain. Moreover, the enzyme possessed dual function of direct fibrinolysis as well as plasminogen activation. Due to its attractive biochemical and fibrinolytic properties and being from a GRAS fungus, the fibrinolytic enzyme has application as a safe and efficient thrombolytic drug. PMID- 29175168 TI - CD8+ T cells are essential for the effects of enriched environment on hippocampus dependent behavior, hippocampal neurogenesis and synaptic plasticity. AB - Enriched environment (EE) induces plasticity changes in the brain. Recently, CD4+ T cells have been shown to be involved in brain plasticity processes. Here, we show that CD8+ T cells are required for EE-induced brain plasticity in mice, as revealed by measurements of hippocampal volume, neurogenesis in the DG of the hippocampus, spinogenesis and glutamatergic synaptic function in the CA of the hippocampus. As a consequence, EE-induced behavioral benefits depend, at least in part, on CD8+ T cells. In addition, we show that spleen CD8+ T cells from mice housed in standard environment (SE) and EE have different properties in terms of 1) TNFalpha release after in vitro CD3/CD28 or PMA/Iono stimulation 2) in vitro proliferation properties 3) CD8+ CD44+ CD62Llow and CD62Lhi T cells repartition 4) transcriptomic signature as revealed by RNA sequencing. CD8+ T cells purified from the choroid plexus of SE and EE mice also exhibit different transcriptomic profiles as highlighted by single-cell mRNA sequencing. We show that CD8+ T cells are essential mediators of beneficial EE effects on brain plasticity and cognition. Additionally, we propose that EE differentially primes CD8+ T cells leading to behavioral improvement. PMID- 29175169 TI - Outcome of pregnancy with new onset proteinuria and progression to pre-eclampsia: A retrospective analysis. AB - OBJECTIVE: To examine maternal and neonatal outcomes of gestational proteinuria, and to identify maternal characteristics for progression to pre-eclampsia. STUDY DESIGN: Retrospective cohort. Included all pregnant women who delivered between Jan 2014-Feb 2017 with new onset proteinuria in a single obstetric unit. Demographic, maternal and neonatal outcomes were compared. RESULTS: Eighteen (25%) out of 73 women with new onset gestational proteinuria developed pre eclampsia. The incidence of gestational proteinuria was 0.54%. Compared with women that remained normotensive, those that developed hypertension had delivery at earlier gestation (p = .02), increased risk of fetal growth restriction (p = .01) and lower newborn birthweight (p = .002). Maximal proteinuria and fetal growth restriction were independent factors associated with development of pre eclampsia. In particular, high proteinuria level >= 2 g/d constitute a major predictor for progression (p = .03). CONCLUSION: Increased vigilance for antenatal surveillance is important in women with gestational proteinuria as a substantial portion progress to pre-eclampsia. Serial growth scan and proteinuria assay are suggested to predict possible pre-eclampsia development. PMID- 29175170 TI - First-trimester mean arterial blood pressure and the risk of preeclampsia: The Great Obstetrical Syndromes (GOS) study. AB - OBJECTIVE: To estimate the predictive value of first-trimester mean arterial pressure (MAP) for the hypertensive disorders of pregnancy (HDP). STUDY METHODS: We performed a prospective cohort study of nulliparous women recruited at 110/7 136/7 weeks. MAP was calculated from blood pressure measured on both arms simultaneously using an automated device taking a series of recordings until blood pressure stability was reached. MAP was reported as multiples of the median adjusted for gestational age. Participants were followed for development of gestational hypertension (GH), preeclampsia (PE), preterm PE (<37 weeks) and early-onset (EO) PE (<34 weeks). Receiver operating characteristic curves and the area under the curve (AUC) were used to estimate the predictive values of MAP. Multivariate logistic regressions were used to develop predictive models combining MAP and maternal characteristics. RESULTS: We obtained complete follow up in 4700 (99%) out of 4749 eligible participants. GH without PE was observed in 250 (5.3%) participants, and PE in 241 (5.1%), including 33 (0.7%) preterm PE and 10 (0.2%) EO-PE. First-trimester MAP was associated with GH (AUC: 0.77; 95%CI: 0.74-0.80); term PE (0.73; 95%CI: 0.70-0.76), preterm PE (0.80; 95%CI: 0.73-0.87) and EO-PE (0.79; 95%CI: 0.62-0.96). At a 10% false-positive rate, first-trimester MAP could have predicted 39% of GH, 34% of term PE, 48% of preterm PE and 60% of EO-PE. The addition of maternal characteristics improved the predictive values (to 40%, 37%, 55% and 70%, respectively). CONCLUSION: First-trimester MAP is a strong predictor of GH and PE in nulliparous women. PMID- 29175171 TI - Early warning system hypertension thresholds to predict adverse outcomes in pre eclampsia: A prospective cohort study. AB - OBJECTIVES: To evaluate the association between blood pressure (BP) measurements and adverse outcomes in women with pre-eclampsia. STUDY DESIGN: A prospective cohort study of women with pre-eclampsia admitted to three South African tertiary facilities. BP was measured using the CRADLE Vital Signs Alert (VSA), incorporated with a traffic light early warning system; green: systolic BP <140 mmHg and diastolic BP <90 mmHg, yellow: systolic BP 140-159 and/or diastolic BP 90-109 mmHg (but neither is above the upper threshold), red: systolic BP >=160 mmHg and/or diastolic BP >=110 mmHg. MAIN OUTCOME MEASURES: Maternal: death, eclampsia, stroke, kidney injury; process measures: magnesium sulfate use, Critical Care Unit (CCU) admission; perinatal: stillbirth, neonatal death, preterm delivery. RESULTS: Of 1547 women with pre-eclampsia (including 42 twin pregnancies), 33.0% of women triggered a red light on admission and 78.6% at their highest BP. Severe hypertension and adverse outcomes were common across yellow and red categories. Comparing admission red to yellow lights, there was a significant increase in kidney injury (OR 1.74, CI 1.31-2.33, trend test p = .003), magnesium sulfate use (OR 3.40, CI 2.24-5.18, p < .001) and CCU admission (OR 1.50, CI 1.18-1.91, p < .001), but not for maternal death, eclampsia, extended perinatal death or preterm delivery. CONCLUSION: The CRADLE VSA, with integrated traffic light early warning system, can identify women who are hypertensive, at increased risk of severe pre-eclampsia complications and in need of escalation of care. Women who triggered a red light were at increased risk of kidney injury, magnesium sulfate use and CCU admission. PMID- 29175172 TI - A diagnostic curiosity of isolated androstenedione elevation due to autoantibodies against horseradish peroxidase label of the immunoassay. AB - Two sisters with hirsutism presented with mild hirsutism and isolated, grossly elevated (>34.9nmol/L) serum concentrations of androstenedione measured by competitive, homogeneous immunoassay. The clinically discordant laboratory results prompted us to look for assay interference. In this immunoassay, horseradish peroxidase (HRP)-conjugated androstenedione competes with endogenous androstenedione for binding with the solid-phase polyclonal rabbit IgG antibodies. After a wash step, the amount of signal generated by the bound HRP conjugate is inversely proportional to the androstenedione concentration. Alternative analysis by tandem mass spectrometry (a good first line option for troubleshooting) and repeating the competitive immunoassay after polyethylene glycol treatment returned androstenedione concentrations within reference limits. These findings suggested that the original result was spuriously elevated due to assay interference. Additionally, the patient samples were pre-incubated with heterophile blocking reagents, normal rabbit IgG antibodies and HRP-conjugated normal goat IgG antibodies, followed by repeat measurement using the immunoassay. Only samples pre-incubated with HRP-conjugate returned significantly lower androstenedione (9.5 and 12.5nmol/L, respectively), implying neutralisation of the interfering antibodies. Androstenedione remained grossly elevated in the other experiments. This deductive exercise showed that the interference is due to autoantibodies against the HRP label used in the immunoassay. Another immunoassay using HRP label (5alpha-dihydrotestosterone) also produced gross elevation that was normal by tandem mass spectrometry analysis. Assay interferences, though not uncommon, are frequently overlooked. Laboratory results discordant with clinical features should prompt consideration of assay interference to avoid unnecessary investigations and treatment. This is the first report of autoantibodies against the HRP label used in immunoassay. PMID- 29175173 TI - Diagnostic and clinical significance of the titin fragment in urine of Duchenne muscular dystrophy patients. AB - Duchenne muscular dystrophy (DMD) is a fatal progressive muscle wasting disease of childhood. Titin in sarcomere is digested by calcium dependent protease. To explore muscle damage in DMD, the urinary concentrations of the N-terminal fragment of titin were determined using a newly developed enzyme linked immune sorbent assay kit. The urinary titin concentrations were normalized to creatinine (Cr). A total of 145 urine samples were obtained at a single Japanese hospital from 113 DMD patients aged 3-29years. Normalized urinary titin concentration was 965.8+/-1011.9 (Mean+/-SD) pmol/mg Cr in patients with DMD. This was nearly 700 fold higher than healthy children (1.4+/-0.8pmol/mg Cr). The concentration was significantly higher in DMD than in BMD patients who had significantly higher urinary titin than normal. Urinary titin in DMD patients tended to decrease with age. The median concentration of urinary titin in the youngest (aged 3-7years) and oldest (aged >=16years) groups was 1468.3 and 411.3pmol/mg Cr, respectively, with significant difference. Urinary concentration of titin correlated significantly with serum creatine kinase concentration, the best-known biomarker of DMD. The N-terminal fragment of titin in urine has potential as a diagnostic and clinical biomarker for DMD.

A single blood sample was taken from cows (N=31; age: 9.06+/-0.98years) to determine systemic AMH. Animals with concentrations higher or lower than 194+/ 30pg/ml were placed into LOW and HIGH AMH groups and were assigned randomly to be superovulated FSH containing either a high (FSHp, HLH) or low (FolltropinV, LLH) LH content. Follicular growth and ovulation were monitored using transrectal ultrasonography. In animals with HIGH systemic AMH, treatment with FSH with a high LH content was associated with more small follicles (AMH X FSH; P=0.02). AMH had no effect on small follicles in animals treated with LLH. Females with a HIGH AMH had greater numbers of small follicles (P=0.01) and total follicles (P=0.005) than LOW AMH cows. Animals treated with HLH had more small follicles (P=0.001) but fewer large (P<0.001) and total follicles (P=0.0005) than those treated with LLH. Among animals with HIGH AMH, those treated with LLH, ovulated more follicles than those treated with HLH. (AMH X FSH; P=0.03). In conclusion, selecting animals with high AMH concentration and the use of FSH preparations with a lower LH content may improve the superovulatory response in water buffaloes. PMID- 29175176 TI - Expression of sex hormone receptors in the brain of male and female newly hatched chicks. AB - Chromosomal sex and steroid hormones play a determining role in brain sexual differentiation during chick embryonic development. Hormone effects on the brain are associated with the expression pattern of their intracellular receptors, which is sexually dimorphic in many species. We determined by Western blot the content of progesterone, estrogen, and androgen receptors (PR-A and PR-B, ERalpha, and AR, respectively) in the cortex, cerebellum, tectum, and hypothalamus of female and male newly hatched chicks. Males presented a higher content of PR-B in the tectum whereas females exhibited a higher content of PR-A in the hypothalamus. ERalpha was only detected as a band of 66kDa, and it showed a higher content in the cerebellum and tectum of females as compared to these regions in males. Besides, males exhibited a higher content of AR in the tectum than females. Our study suggests that newly hatched chicks show a sexual dimorphism in the expression of sex hormone receptors in brain regions involved in sexual behavior such as the hypothalamus, and in non-sexual behavior such as the optic tectum and the cerebellum. PMID- 29175177 TI - Associations between management practices and major reproductive parameters of Holstein-Friesian replacement heifers. AB - The aim of this study was to assess the relationship between the reproductive management practices and the performance of replacement heifers on large commercial dairy farms. The individual data of 14,763 heifers, first inseminated in 2014, were analysed from 33 Holstein-Friesian dairy herds in Hungary. The relationships between management practices and major reproductive parameters (age at first service, AFS; age at first calving, AFC; conception risk to first insemination, CR1; and pregnancy status at 20 months of age) were examined by mixed-effects models, with the herd as the random effect. The results showed that farms using oestrus detection aids experienced reduced AFS (p<0.001) and AFC (p=0.001). Observation of oestrus for shorter periods instead of continuously showed a tendency towards lower AFC (p=0.057) and was associated with higher odds of pregnancy at 20 months of age (p=0.020). Heifers on farms using sexed semen had younger AFS, but poorer CR1, compared to those using conventional semen exclusively (p<0.05). In addition, the odds of heifers being pregnant by 20 months of age was higher on farms with more experience using sexed semen (p=0.020). Frequent pregnancy diagnosis (i.e. more than once per week) was associated with younger AFC (p=0.023). Our results suggest the use of certain advanced reproductive management practices for heifer reproductive management in large dairy herds (e.g. oestrus detection aids), which can improve reproductive efficiency considerably, but are currently used only to a limited extent. PMID- 29175178 TI - Effect of serum paraoxonase-1 (PON1) activity on follicular development and pregnancy rate in cattle. AB - Paraoxonase-1 (PON1) activity has been associated with improvement in ovarian function in early postpartum dairy cows and improved in vitro embryo development. The aim of the current study was to evaluate the potential association among PON1 activity and follicular growth, diameter of the preovulatory follicle and pregnancy per artificial insemination (AI) service in cattle. In Experiment 1, cows (n=33) were subjected to an estradiol-progesterone based protocol to control time of ovulation. Starting on Day 8 of the protocol, follicular growth and serum PON1 activity were monitored. Cows were separated according to the occurrence of ovulation into two groups: Ovulatory (Ov; n=22) and Anovulatory (Anov; n=11). The serum activity of PON1 was not different between Ov and Anov cows (P=0.94). In addition, using a regression model there was no effect of serum PON1 activity on the diameter of dominant follicle (r2=0.00; P=0.99). In Experiment 2, cows (n=193) were submitted to the same hormonal protocol as in Experiment 1. On the day of the timed artificial insemination (TAI), the diameter of dominant follicle was evaluated and blood samples were collected for analysis of PON1 activity. According to the serum PON1 activity, cows were divided into three groups: Low (<70U/mL), Medium (70-90U/mL) or High (>90U/mL) PON1 activity. The overall pregnancy rate was 62.7% (121/193), with no difference among PON1 activity groups. Additionally, using a regression model there was no effect of serum PON1 activity on the diameter of the preovulatory follicle (r2=0.03; P=0.65) and pregnancy rate (r2=0.005; P=0.94). The results of this study indicate that there is no effect of serum PON1 activity on the diameter of preovulatory follicle or establishment of pregnancy in cows submitted to time of ovulation synchronization protocols. PMID- 29175179 TI - Effects of oxytocin and PGF2alpha on uterine contractility in cows with and without metritis-An in-vitro study. AB - The aim of this study was to investigate the effects of PGF2alpha and oxytocin in vitro on myometrial contractility in puerperal uteri. Thirteen puerperal uteri were removed and perfused after euthanasia of cows with (n=7) and without metritis (n=6). Measurement of uterine contractility was done using four piezoelectric crystals, which were implanted into the myometrium along the greater curvature of the uterine horn where fetal implantation occurred during the previous pregnancy. After 30min of equilibration, oxytocin (5 IU) or PGF2alpha (2.5mg Dinoprost) was administered randomly into both uterine arteries, and 30min later, the second administration of either oxytocin or PGF2alpha occurred. Treatment with oxytocin induced contractions in uteri with metritis and uteri without metritis (P<0.05). In uteri with metritis, greater uterine contractions occurred after stimulation with oxytocin than in uteri without metritis (P<0.05). Treatment with PGF2alpha did not (P>0.05) result in increased contractions in the uteri without metrtitis, however, induced an initial decrease in contractions followed by an increase (P<0.05) in contractions in uteri with metritis. Myometrial and endometrial gene expression of PGF2alpha (FPR) and oxytocin receptor (OTR) was greater (P<0.05) in uteri with metritis than in uteri without metritis. The results suggest that oxytocin, but not PGF2alpha, is an effective uterotonic drug in puerperal cows. Uteri in which metritis was diagnosed contracted more strongly after treatment with oxytocin than uteri in which metritis was not diagnosed. This effect was paralleled by greater gene expression of OTR as well as FPR in uteri with metritis compared with uteri in which metritis was not diagnosed. PMID- 29175180 TI - Efflux transport of estrogen glucuronides by human MRP2, MRP3, MRP4 and BCRP. AB - Estrone, estradiol and estriol are endogenous human estrogens that are rapidly conjugated with glucuronic acid in both intestinal and hepatic epithelial cells. The resulting glucuronides, estrone-3-glucuronide (E1-G), estradiol-3- and 17 glucuronides (E2-3G and E2-17G), as well as estriol-3- and 16-glucuronides (E3-3G and E3-16G) are found in human plasma and urine. Unlike E2-17G, the efflux transport of other estrogen glucuronides by human transporters has not yet been investigated comprehensively. We have studied the transport of E1-G, E2-3G, E3 3G, E3-16G and estrone-3-sulfate (E1-S), another important estrogen conjugate, using the vesicular transport assay with recombinant human MRP2, MRP3, MRP4, MDR1 and BCRP that were expressed in insect cells. The transport screening assays revealed that whereas E1-S was a good and specific substrate for BCRP, the less transporter-specific conjugates, E1-G and E2-3G, were still transported by BCRP at 10-fold higher rates than E1-S. BCRP also transported E3-16G at higher rates than the studied MRPs, while it transported E3-3G at lower rates than MRP3. MRP2 exhibited lower or equal transport rates of E1-G, E2-3G, E3-3G and E3-16G in comparison to MRP3 and BCRP in the screening assays, mainly due to its high Km values, between 180 and 790 MUM. MRP3 transported all the tested glucuronides at rather similar rates, at Km values below 20 MUM, but lower Vmax values than other transporters. In the case of E3-3G, MRP3 was the most active transporter in the screening assay. MRP4 transported only E3-16G at considerable rates, while none of the tested estrogen conjugates was transported by MDR1 at higher rates than control vesicles. These new results, in combination with previously reported in vivo human data, stimulate our understanding on the substrate specificity and role of efflux transporters in disposition of estrogen glucuronides in humans. PMID- 29175181 TI - Cross-cultural adaptation and measurement properties of the Brazilian Version of the Michigan Neuropathy Screening Instrument. AB - BACKGROUND: The Michigan Neuropathy Screening Instrument is an easy-to-use questionnaire aimed at screening and detecting diabetic polyneuropathy. OBJECTIVE: To translate and cross-culturally adapt the MNSI to Brazilian Portuguese and evaluate its measurement properties. METHODS: Two bilingual translators translated from English into Brazilian Portuguese and made a synthetic version. The synthetic version was back translated into English. A committee of specialists and the translator checked the cultural adaptations and developed a pre-final questionnaire in Brazilian Portuguese (prefinal version). In pretesting, the prefinal version was applied to a sample of 34 subjects in which each subject was interviewed to determine whether they understood each item. For the later assessment of measurement properties, 84 subjects were assessed. RESULTS: A final Brazilian Portuguese version of the instrument was produced after obtaining 80% agreement (SEM<0.01%) among diabetic patients and specialists. We obtained excellent intra-rater reliability (ICC3,1=0.90), inter rater reliability (ICC2,1=0.90) and within-subject reliability ICC3,1=0.80, excellent internal consistency (Cronbach's alpha>0.92), reasonable construct validity for the association between the MNSI and Neuropathy Symptom Score (r=0.46, p<0.05) and excellent association between the MNSI and Neuropathy Disability Score (r=0.79, p<0.05). We did not detect floor and ceiling effects (<9.5% of patients with maximum scores). CONCLUSIONS: The Brazilian Portuguese version of the MNSI is suitable for application in the Brazilian diabetic population and is a reliable tool for the screening and detection of DPN. The MNSI can be used both in clinical practice and also for research purposes. PMID- 29175182 TI - Impact of diesel exhaust exposure on the liver of mice fed on omega-3 polyunsaturated fatty acids-deficient diet. AB - Exposure to diesel exhaust (DE) exacerbates non-alcoholic fatty liver disease, and may systemically affect lipid metabolism. Omega-3 polyunsaturated fatty acids (n-3 PUFA) have anti-inflammatory activity and suppresses hepatic triacylglycerol accumulation, but many daily diets are deficient in this nutrient. Therefore, the effect of DE exposure in mice fed n-3 PUFA-deficient diet was investigated. Mice were fed control chow or n-3 PUFA-deficient diet for 4 weeks, then exposed to clean air or DE by inhalation for further 4 weeks. Liver histology, plasma parameters, and expression of fatty acid synthesis-related genes were evaluated. N-3 PUFA-deficient diet increased hepatic lipid droplets accumulation and expression of genes promoting fatty acid synthesis: Acaca, Acacb, and Scd1. DE further increased the plasma leptin and the expression of fatty acid synthesis related genes: Acacb, Fasn, and Scd1. N-3 PUFA-deficient diet and DE exposure potentially enhanced hepatic fatty acid synthesis and subsequently accumulation of lipid droplets. The combination of low-dose DE exposure and intake of n-3 PUFA deficient diet may be an additional risk factor for the incidence of non alcoholic fatty liver disease. The present study suggests an important mechanism for preventing toxicity of DE on the liver through the incorporation of n-3 PUFAs in the diet. PMID- 29175183 TI - Benefit and risk assessment of increasing potassium intake by replacement of sodium chloride with potassium chloride in industrial food products in Norway. AB - High sodium chloride (NaCl) intake is associated with health risks. NaCl may be replaced by potassium chloride (KCl) to decrease sodium intake. However, increased potassium may also have negative health effects. We conducted a benefit and risk assessment of increasing potassium by ratios of 30:70, 50:50, 70:30 (weight % K+: weight % Na+) in children, adolescents and adults in Norway, using intake data from national food consumption surveys and available literature on potassium health effects. An intake of at least 3.5 g/day of potassium decreases risk of stroke and hypertension, and this level was used in the benefit assessment of the healthy population. Three g/day of potassium added to mean food intake is assumed safe, and these levels were used in the risk assessment. Not all persons reached the protective level of potassium, and increasing numbers exceeded the safe levels, in these scenarios. In addition, elderly above 85 years and infants below one year of age, as well as several patient groups and medication users, are particularly vulnerable to hyperkalemia. In conclusion, the number of Norwegians facing increased risk is far greater than the number likely to benefit from this replacement of sodium with potassium in industrially produced food. PMID- 29175184 TI - Assessment of workers' exposure to microorganisms when using biological degreasing stations. AB - Biological degreasing stations (BDSs) are used by mechanics. These BDSs use a water-based solution with a microbial degradation process. Occupational exposure during the use of BDSs has not been reported and few studies have identified the bacteria present. The objectives were to measure the concentration of microorganisms during BDSs' use and monitor the bacterial community in the liquid over time. Five mechanical workshops were studied. Six 30-min samples were taken at each workshop over one year. Bioaerosols in the ambient air samples were collected with Andersen impactors near the BDS Bioaerosols in the workers' breathing zone (WBZ) were collected on filters. Fresh bio-degreasing fluids were collected from unopened containers, and used bio-degreasing fluids were collected in the BDS. The results show that the use of BDSs does not seem to increase bioaerosols concentrations in the WBZ (concentrations lower than 480 CFU/m3) and that the bacterial communities (mainly yeasts, Bacillus subtilis and Pseudomonas aeruginosa) in the bio-degreasing fluids change through time and differ from the original community (B. subtilis). This study established that workers using BDSs were exposed to low levels of bioaerosols. No respiratory protection is recommended based on bioaerosols concentrations, but gloves and strict personal hygiene practices are essential.

PMID- 29175187 TI - Safety assessment of the use of Bacillus-based cleaning products. AB - Non-pathogenic Bacillus species used in cleaning products produce the appropriate enzymes to degrade stains and soils. However, there is little scientific data regarding the human exposure by inhalation of Bacillus spores during or after use of microbial-based cleaning products. Herein, air samples were collected at various locations in a ventilated, carpeted, residential room to determine the air concentration of viable bacteria and spores during and after the application of microbial-based carpet cleaning products containing Bacillus spores. The influence of human activities and vacuuming was investigated. Bioaerosol levels associated with use and post-application activities of whole room carpet treatments were elevated during post-application activity, but quickly returned to the indoor background range. Use of trigger spray spot applications generated aerosolized spores in the immediate vicinity, however, their use pattern and the generation of mostly non-respirable particles suggest minimal risks for pulmonary exposure from their use. The aerosol counts associated with use of these microbial-based cleaners were below the recommendation for safe exposure levels to non-pathogenic and non-toxigenic microorganisms except during application of the spot cleaner. The data presented suggest that carpet cleaning products, containing non-pathogenic Bacillus spores present a low potential for inhalation exposure and consequently minimal risk of adverse effects.

AB - The classical non-transmembrane protein tyrosine phosphatase 1B (PTP1B) has emerged as a key negative regulator of insulin signaling pathways that leads to insulin resistance, turning this enzyme a promising therapeutic target in the management of type 2 diabetes mellitus (T2DM). In the present work, the in vitro inhibitory activity of a panel of structurally related flavonoids, for recombinant human PTP1B was studied and the type of inhibition of the most active compounds further evaluated. The majority of the studied flavonoids was tested in this work for the first time, including flavonoid C13, which was the most potent inhibitor. It was observed that the ability to inhibit PTP1B depends on the nature, position and number of substituents in the flavonoid structure, as the presence of both 7- and 8-OBn groups in the A ring, together with the presence of both 3' and 4'-OMe groups in the B ring and the 3-OH group in the C ring; these substituents increase the flavonoids' ability to inhibit PTP1B. In conclusion, some of the tested flavonoids seem to be promising PTP1B inhibitors and potential effective agents in the management of T2DM, by increasing insulin sensitivity.

PMID- 29175194 TI - Brain signature of mild stages of cognitive and behavioral impairment in amyotrophic lateral sclerosis. AB - We aimed to assess the brain signature of cognitive and behavioral impairment in C9orf72-negative non-demented ALS patients. The study included 50 amyotrophic lateral sclerosis (ALS) patients (out of 75 initially recruited) and 38 healthy controls. High-resolution T1-weighted and spin-echo diffusion tensor images were acquired in a 3T MRI scanner. The multi atlas-based analysis protocol and the FreeSurfer tool were employed for gray matter assessment, and fiber tractography for white matter evaluation. Cognitively impaired ALS patients (n = 12) had bilateral amygdalae and left thalamic volumetric reduction compared to non impaired ALS patients. Behaviorally impaired ALS patients (n = 14) had lower fractional anisotropy (FA) at the fornix in comparison with healthy subjects. These parameters did correlate with cognitive/behavioral scores, but not with motor-functional parameters in the ALS cohort. We believe that basal ganglia and fornix damage might be related to cognitive and behavioral impairment across ALS frontotemporal dementia continuum. Also, distinct anatomical areas seem to influence the behavioral and cognitive status of these individuals.

AB - AIM: Diabetes is a growing public health problem in India which is soon going to become the 'diabetes capital' of the world. It requires regular care and follow up. We aimed to estimate the household out-of-pocket (OOP) expenditure and catastrophic expenditure due to hospitalization and outpatient care as a result of diabetes. MATERIALS AND METHODS: Secondary analysis of nationally representative data for India collected by National Sample Survey Organization in 2014, reporting on health service utilization and health care related OOP expenditure by income quintiles and by type of health facility (public or private). RESULTS: The median household OOP expenditure from hospitalization due to diabetes was USD 151, and was 3 times higher among the richest quintile compared to the poorest quintile (p<0.001). There was a significantly higher prevalence (p<0.001) of catastrophic expenditure among the poorest quintile (36%) compared to the richest (14%). Median private sector OOP hospitalization expenditure was four times higher than the public sector (p<0.001). Medicines accounted for 41% and 69% of public sector hospitalization and outpatient care respectively. Concentration indices show gross inequity in hospitalization expenditure, prevalence of catastrophic expenditure and utilization of public health facility. CONCLUSION: Households with diabetic patients incur a high risk of catastrophic expenditure, particularly for those in the lowest income quintiles and those seeking care in the private sector. Increased availability and access to essential drugs and strengthening of public facilities will significantly reduce OOP expenditure. PMID- 29175199 TI - Towards a neurodynamical understanding of the prodrome in schizophrenia. AB - The identification of biomarkers for the early diagnosis of schizophrenia that could inform novel treatment developments is an important objective of current research. This paper will summarize recent work that has investigated changes in oscillatory activity and event-related potentials with Electro/Magnetoencephalography (EEG/MEG) in participants at high-risk for the development of schizophrenia, highlighting disruptions in sensory and cognitive operations prior to the onset of the syndrome. Changes in EEG/MEG-data are consistent with evidence for alterations in Glutamatergic and GABAergic neurotransmission as disclosed by Magnetic Resonance Spectroscopy and brain stimulation, indicating changes in Excitation/Inhibition balance parameters prior to the onset of psychosis. Together these data emphasize the importance of research into neuronal dynamics as a crucial approach to establish functional relationships between impairments in neural circuits and emerging psychopathology that together could be fundamental for early intervention and the identification of novel treatments for emerging psychosis. PMID- 29175200 TI - Quasi-periodic patterns of intrinsic brain activity in individuals and their relationship to global signal. AB - Quasiperiodic patterns (QPPs) as reported by Majeed et al., 2011 are prominent features of the brain's intrinsic activity that involve important large-scale networks (default mode, DMN; task positive, TPN) and are likely to be major contributors to widely used measures of functional connectivity. We examined the variability of these patterns in 470 individuals from the Human Connectome Project resting state functional MRI dataset. The QPPs from individuals can be coarsely categorized into two types: one where strong anti-correlation between the DMN and TPN is present, and another where most areas are strongly correlated. QPP type could be predicted by an individual's global signal, with lower global signal corresponding to QPPs with strong anti-correlation. After regression of global signal, all QPPs showed strong anti-correlation between DMN and TPN. QPP occurrence and type was similar between a subgroup of individuals with extremely low motion and the rest of the sample, which shows that motion is not a major contributor to the QPPs. After regression of estimates of slow respiratory and cardiac induced signal fluctuations, more QPPs showed strong anti-correlation between DMN and TPN, an indication that while physiological noise influences the QPP type, it is not the primary source of the QPP itself. QPPs were more similar for the same subjects scanned on different days than for different subjects. These results provide the first assessment of the variability in individual QPPs and their relationship to physiological parameters. PMID- 29175201 TI - Neuroanatomical substrate of noise sensitivity. AB - Recent functional studies suggest that noise sensitivity, a trait describing attitudes towards noise and predicting noise annoyance, is associated with altered processing in the central auditory system. In the present work, we examined whether noise sensitivity could be related to the structural anatomy of auditory and limbic brain areas. Anatomical MR brain images of 80 subjects were parcellated with FreeSurfer to measure grey matter volume, cortical thickness, cortical area and folding index of anatomical structures in the temporal lobe and insular cortex. The grey matter volume of amygdala and hippocampus was measured as well. According to our findings, noise sensitivity is associated with the grey matter volume in the selected structures. Among those, we propose and discuss particular areas, previously linked to auditory perceptual, emotional and interoceptive processing, in which larger grey matter volume seems to be related to higher noise sensitivity. PMID- 29175202 TI - Brain correlates of constituent structure in sign language comprehension. AB - During sentence processing, areas of the left superior temporal sulcus, inferior frontal gyrus and left basal ganglia exhibit a systematic increase in brain activity as a function of constituent size, suggesting their involvement in the computation of syntactic and semantic structures. Here, we asked whether these areas play a universal role in language and therefore contribute to the processing of non-spoken sign language. Congenitally deaf adults who acquired French sign language as a first language and written French as a second language were scanned while watching sequences of signs in which the size of syntactic constituents was manipulated. An effect of constituent size was found in the basal ganglia, including the head of the caudate and the putamen. A smaller effect was also detected in temporal and frontal regions previously shown to be sensitive to constituent size in written language in hearing French subjects (Pallier et al., 2011). When the deaf participants read sentences versus word lists, the same network of language areas was observed. While reading and sign language processing yielded identical effects of linguistic structure in the basal ganglia, the effect of structure was stronger in all cortical language areas for written language relative to sign language. Furthermore, cortical activity was partially modulated by age of acquisition and reading proficiency. Our results stress the important role of the basal ganglia, within the language network, in the representation of the constituent structure of language, regardless of the input modality. PMID- 29175203 TI - Effects of bilingualism on white matter integrity in older adults. AB - Bilingualism can delay the onset of dementia symptoms and has thus been characterized as a mechanism for cognitive or brain reserve, although the origin of this reserve is unknown. Studies with young adults generally show that bilingualism is associated with a strengthening of white matter, but there is conflicting evidence for how bilingualism affects white matter in older age. Given that bilingualism has been shown to help stave off the symptoms of dementia by up to four years, it is crucial that we clarify the mechanism underlying this reserve. The current study uses diffusion tensor imaging (DTI) to compare monolinguals and bilinguals while carefully controlling for potential confounds (e.g., I.Q., MMSE, and demographic variables). We show that group differences in Fractional Anisotropy (FA) and Radial Diffusivity (RD) arise from multivariable interactions not adequately controlled for by sequential bivariate testing. After matching and statistically controlling for confounds, bilinguals still had greater axial diffusivity (AD) in the left superior longitudinal fasciculus than monolingual peers, supporting a neural reserve account for healthy older bilinguals. PMID- 29175204 TI - Cerebral peak alpha frequency predicts individual differences in pain sensitivity. AB - The identification of neurobiological markers that predict individual predisposition to pain are not only important for development of effective pain treatments, but would also yield a more complete understanding of how pain is implemented in the brain. In the current study using electroencephalography (EEG), we investigated the relationship between the peak frequency of alpha activity over sensorimotor cortex and pain intensity during capsaicin-heat pain (C-HP), a prolonged pain model known to induce spinal central sensitization in primates. We found that peak alpha frequency (PAF) recorded during a pain-free period preceding the induction of prolonged pain correlated with subsequent pain intensity reports: slower peak frequency at pain-free state was associated with higher pain during the prolonged pain condition. Moreover, the degree to which PAF decreased between pain-free and prolonged pain states was correlated with pain intensity. These two metrics were statistically uncorrelated and in combination were able to account for 50% of the variability in pain intensity. Altogether, our findings suggest that pain-free state PAF over relevant sensory systems could serve as a marker of individual predisposition to prolonged pain. Moreover, slowing of PAF in response to prolonged pain could represent an objective marker for subjective pain intensity. Our findings potentially lead the way for investigations in clinical populations in which alpha oscillations and the brain areas contributing to their generation are used in identifying and formulating treatment strategies for patients more likely to develop chronic pain.

AB - Adults with anomalous left coronary artery from the pulmonary artery typically have multiple venous and arterial collateral arteries surrounding the artery, making precise ligation imperative. Most physicians delay mitral valve repair until left ventricular function improves allowing for reperfusion through a 2 coronary system reimplanting the anomalous left coronary artery from the pulmonary artery into the aorta. PMID- 29175206 TI - Stochastic simulation of multiscale complex systems with PISKaS: A rule-based approach. AB - Computational simulation is a widely employed methodology to study the dynamic behavior of complex systems. Although common approaches are based either on ordinary differential equations or stochastic differential equations, these techniques make several assumptions which, when it comes to biological processes, could often lead to unrealistic models. Among others, model approaches based on differential equations entangle kinetics and causality, failing when complexity increases, separating knowledge from models, and assuming that the average behavior of the population encompasses any individual deviation. To overcome these limitations, simulations based on the Stochastic Simulation Algorithm (SSA) appear as a suitable approach to model complex biological systems. In this work, we review three different models executed in PISKaS: a rule-based framework to produce multiscale stochastic simulations of complex systems. These models span multiple time and spatial scales ranging from gene regulation up to Game Theory. In the first example, we describe a model of the core regulatory network of gene expression in Escherichia coli highlighting the continuous model improvement capacities of PISKaS. The second example describes a hypothetical outbreak of the Ebola virus occurring in a compartmentalized environment resembling cities and highways. Finally, in the last example, we illustrate a stochastic model for the prisoner's dilemma; a common approach from social sciences describing complex interactions involving trust within human populations. As whole, these models demonstrate the capabilities of PISKaS providing fertile scenarios where to explore the dynamics of complex systems. PMID- 29175207 TI - Dynasore suppresses proliferation and induces apoptosis of the non-small-cell lung cancer cell line A549. AB - Lung cancer is the leading cause of cancer death worldwide, and most of all cases are non-small-cell lung cancer. Lung cancer is associated with dysregulation of mitochondrial fusion and fission, and inhibition of the fission regulator Dynamin related protein 1 (Drp1) reduces proliferation and increases apoptosis of lung cancer cells. Dynasore is a small molecule non-selective inhibitor of the GTPase activity of dynamin 1, dynamin 2, and Drp1 in vivo and in vitro. Here, we investigated the effects of dynasore on the proliferation and apoptosis of A549 lung cancer cells, alone and in combination with the chemotherapeutic drug cisplatin. We found that cisplatin increased mitochondrial fission and dynamin 2 expression, whereas dynasore had the opposite effects. However, both cisplatin and dynasore independently induced mitochondrial oxidative stress, leading to mitochondrial dysfunction, reduced cell proliferation, and enhanced apoptosis. Importantly, dynasore significantly augmented the anti-cancer effects of cisplatin. To the best of our knowledge, this is the first report that dynasore inhibits proliferation and induces apoptosis of lung cancer cells, and enhances the inhibitory effects of cisplatin. PMID- 29175208 TI - Overexpression of acetyl CoA carboxylase beta exacerbates podocyte injury in the kidney of streptozotocin-induced diabetic mice. AB - A single nucleotide polymorphism (SNP) within the acetyl CoA carboxylase (ACC) beta gene (ACACB), rs2268388, has been shown to be associated with susceptibility to development of proteinuria in patients with type 2 diabetes. To investigate the biological roles of ACCbeta in the pathogenesis of diabetic nephropathy, we examined the effects of overexpression of ACACB using podocyte-specific ACACB transgenic mice or ACACB-overexpressing murine podocytes. Podocyte-specific ACACB transgenic mice or littermate mice were treated with streptozotocin (STZ) to induce diabetes, and 12 weeks after induction of diabetes, we examined the expression of podocyte markers to evaluate the degree of podocyte injury in these mice. We also examined the effects of ACCbeta on podocyte injury in ACACB- or LacZ-overexpressing murine podocytes. Podocyte-specific ACACB overexpression did not cause visible podocyte injury in non-diabetic mice. In STZ-induced diabetic mice, ACACB-transgenic mice showed a significant increase in urinary albumin excretion, accompanied by decreased synaptopodin expression and podocin mislocalization in podocytes, compared with wild-type mice. In cultured murine podocytes, overexpression of ACACB significantly decreased synaptopodin expression and reorganized stress fibers under high glucose conditions, but not in normal glucose conditions. The decrease of synaptopodin expression and reorganized stress fibers observed in ACACB overexpressing cells cultured under high glucose conditions was reversed by a treatment of 5-aminoimidazole-4 carboxamide-1-beta-4-ribofuranoside (AICAR), activator of AMP-activated protein kinase (AMPK). The excess of ACCbeta might contribute to exacerbation of podocyte injury in the kidney of an animal model for diabetes mellitus, and the AMPK/ACCbeta pathway may be a novel therapeutic target for the prevention of diabetes-related podocyte injury.

AB - Cardiovascular disease remains a worldwide public health issue. As fructose consumption is dramatically increasing, it has been demonstrated that a fructose rich intake would increase the risk of cardiovascular disease. In addition, emerging evidences suggest that low concentration alcohol intake may exert a protective effect on cardiovascular system. This study aimed to investigate whether low-concentration alcohol consumption would prevent the adverse effects on cardiovascular events induced by high fructose in mice. From the results of hematoxylin-eosin staining, echocardiography, heart weight/body weight ratio and the expression of hypertrophic marker ANP, we found high-fructose result in myocardial hypertrophy and the low-concentration alcohol consumption would prevent the cardiomyocyte hypertrophy from happening. In addition, we observed low-concentration alcohol consumption could inhibit mitochondria swollen induced by high-fructose. The elevated levels of glucose, triglyceride, total cholesterol in high-fructose group were reduced by low concentration alcohol. Low expression levels of SIRT1 and PPAR-gamma induced by high-fructose were significantly elevated when fed with low-concentration alcohol. The histone lysine 9 acetylation (acH3K9) level was decreased in PPAR-gamma promoter in high-fructose group but elevated when intake with low concentration alcohol. The binding levels of histone deacetylase SIRT1 were increased in the same region in high-fructose group, while the low concentration alcohol can prevent the increased binding levels. Overall, our study indicates that low-concentration alcohol consumption could inhibit high-fructose related myocardial hypertrophy, cardiac mitochondria damaged and disorders of glucose-lipid metabolism. Furthermore, these findings also provide new insights into histone acetylation-deacetylation mechanisms of low-concentration alcohol treatment that may contribute to the prevention of cardiovascular disease induced by high-fructose intake. PMID- 29175210 TI - Participation of cysteine 30 residue in the folding process of ovalbumin evaluated in a refolding experiment using cysteine mutants. AB - To understand the role of cysteine (SH) residues in the folding of hen ovalbumin (OVA), SH-mutated OVAs, in which each SH residue was replaced by alanine (C11A, C30A, C367A, and C382A), were prepared. SDS-PAGE analysis under non-reducing conditions showed that the C11A and C30A mutants produced a disulfide (SS) isomer in addition to a protein with a native SS bond (Cys73-Cys120). The susceptibility to elastase digestion suggested that the Cys73 residue in the SS isomer participates as a counterpart of the SS bond. Upon refolding of the SH-mutated OVAs under the denatured and SS-reduced states, only C30A failed to refold into an intact form. This indicated that the Cys30 residue plays an important role in correct refolding. To confirm this, each of the four SH-mutated OVAs, in which the original SS-forming sites (C11/73/120A, C30/73/120A, C73/120/367A, and C73/120/382A) were deleted, was constructed and expressed. The C11/73/120A and C30/73/120A mutants formed no SS form, in contrast to C73/120A as a control. Thus, we concluded that Cys30 participates in the correct folding of OVA, and that its SS bond (Cys11-Cys30) is transiently generated during the early folding stage to avoid misfolding, and then the native SS form of OVA is regenerated through SH-SS exchanges. PMID- 29175211 TI - Nutlin sensitizes lung carcinoma cells to interferon-alpha treatment in MDM2 dependent but p53-independent manner. AB - As an anticancer therapeutic, Interferon-alpha (IFNalpha) is used to treat a number of malignancies. However, the application of IFNalpha is restricted mostly due to its high toxicity. Therefore, novel combination therapeutic regimens are required to decrease the toxicity of IFNalpha and enhance its efficacy. Here we show that the treatment of p53-deficient human non-small lung carcinoma H1299 cells with IFNalpha in combination with an inhibitor of MDM2, Nutlin-3a, synergistically affects the proliferation of cancer cells. Importantly, Nutlin-3a was able to reduce the effective dose of IFNalpha about 3.4 times. Strikingly, this phenomenon is p53-independent, because H1299 cells lack p53, but is highly dependent on MDM2 because its ablation makes tumor cells completely insensitive to IFNalpha alone or in combination with Nutlin-3a. On the contrary, overexpression of MDM2 makes H1299 cells more susceptible to both IFNalpha and IFNalpha/Nutlin-3a treatments. Mechanistically, treatment with combination of IFNalpha and Nutlin-3a attenuates cyclin D1/CDK4 on the protein level and hence blocks cell cycle progression. This mechanism may be responsible, at least in part, for the anti-proliferative effects on H1299 cells observed. Our data suggest that the expression of MDM2 confers sensitivity of cancer cells to IFNalpha/Nutlin-3a treatment. Moreover, our data also confirm positive effect of Nutlin even on p53-deficient neoplasms. PMID- 29175212 TI - Role of pyroptosis in normal cardiac response to calorie restriction and starvation. AB - AIMS: An unhealthy diet is a major risk factor for cardiac diseases. Most researches focus on high fat diet, little is known about the detrimental effects of starvation on heart. METHODS: Mice were fed 100%, 40% and 20% of ad libitum to mimic the situation of moderate and severe caloric restriction (CR). To further evaluate the different effect of CR and starvation on cardiomyocyte, AC16 cells were treated with different concentrations of serum or glucose. TUNEL staining was performed to evaluate DNA damage in AC16 cells. HE and Masson staining were performed to detect the morphology and degree of fibrosis in myocardium from mice. Immunohistochemical staining, immunofluorescence staining, western blot and real-time PCR were used to detect the protein and mRNA expression of caspase-1, IL-1beta and IL-18. RESULTS: CR and starvation decrease body weight of mice in a concentration dependent manner. The starvation group showed a remarkable myocardial fibrosis with no significant alteration between control and CR groups. CR inhibited the activation of caspase-1 as well as the expression of IL-1beta and IL-18. On the contrary, starvation plays completely opposite effects, which was in accordance with histological changes. Similarly, different levels of serum and glucose deprivation were used to mimic the effect of CR and starvation in vitro. Moderate level of serum and glucose deprivation exerts protective effect on AC16 cells through the inhibition of pyroptosis, whereas high level of serum and glucose deprivation induces cell injury through the induction of pyroptosis. CONCLUSION: CR alleviates pyroptosis, whereas starvation promotes the progression of pyroptosis in myocardial tissues and cells. PMID- 29175213 TI - A new therapeutic proposal for inoperable osteosarcoma: Photodynamic therapy. AB - BACKGROUND: Osteosarcoma, a malignant tumor characterized by bone or osteoid formation, is the second most common primary bone neoplasm. Clinical symptoms include local and surrounding pain, unrelieved by rest or anesthesia. Osteosarcoma has a poor chemotherapeutic response with prognosis dependent on complete tumor excision. Therefore, for inoperable osteosarcoma new therapeutic strategies are needed. The present study aimed to develop murine models of cranial and vertebral osteosarcoma that facilitate simple clinical monitoring and real-time imaging to evaluate the outcome of photodynamic therapy based on a previously developed photosensitizer. METHODS: Balb/c nude mice were divided into two groups: the cranial and vertebral osteosarcoma groups. Each group was further subdivided into the photodynamic therapy-treated and untreated groups. Images were obtained by scintigraphy with 99mTc-MIBI and radiography. Tumor growth, necrotic area, osteoid matrix area, and inflammatory infiltration were analyzed. RESULTS: Cranial and vertebral tumors could be macroscopically observed and measured. Radiographic and scintigraphic images showed tumor cells present at the inoculation sites. After photodynamic therapy, scintigraphy showed lower tumoral radiopharmaceutical uptake, which correlated histologically with increased necrosis. Osteoid matrix volume increased, and tumor size decreased in all photodynamic therapy-treated animals. CONCLUSION: Cranial and vertebral osteosarcoma models in athymic mice are feasible and facilitate in vivo monitoring for the development of new therapies. Photodynamic therapy is a potential antitumoral treatment for surgically inoperable osteosarcoma. PMID- 29175214 TI - Survival in patients with primary dermatofibrosarcoma protuberans: National Cancer Database analysis. AB - BACKGROUND: The predictors of mortality, second surgery, and postoperative radiation therapy for treating dermatofibrosarcoma protuberans (DFSP) are not well described. OBJECTIVE: We sought to determine the impact of patient demographics, tumor characteristics, and treatment site and modality on survival after primary DFSP. METHODS: A retrospective analysis of data from the National Cancer Database was performed for patients diagnosed with DFSP during 2003-2012. RESULTS: A total of 5249 cases were identified. Of these, 3.1% of patients died during an average of 51.4 months of follow-up. After adjusting for relevant factors, lack of insurance, Medicaid and Medicare insurance, anaplastic histology, and positive postoperative margins all predicted mortality, while treatment at an Integrated Network Cancer Program predicted survival (P < .05). Higher odds of postoperative radiation therapy were directly associated with large tumor size, anaplastic and poorly differentiated histology, and positive postoperative margins and inversely associated with treatment at high volume facilities, and non-head and neck tumors. Higher second surgery rates were associated with Hispanic ethnicity, and lower rates were associated with female sex. LIMITATIONS: Survival data was not cancer-specific. CONCLUSION: Better understanding of factors affecting survival outcomes might help improve management of DFSP and delineate other potential causes of increased morbidity and mortality. PMID- 29175215 TI - PdPt nanoparticles anchored on the N-G with the integration of PANI nanohybrids as novel redox probe and catalyst for the detection of rs1801177. AB - Single nucleotide polymorphism (SNP) in lipoprotein lipase (LPL) gene (rs1801177) is strongly associated with the increased progression of atherosclerosis, threatening global public health. In this work, a relatively simple, specific and ultrasensitive electrochemical DNA biosensor was constructed to detect rs1801177 for the first time. A glass carbon electrode was modified with fullerene (C60)/polyamidoamine (PAMAM)/gold (Au) nanoparticles nanocomposites film. In addition the nitrogen-doped graphene (N-G)/palladium platinum (PdPt) bimetallic nanoparticle/ polyaniline (PANI) nanohybrids were synthesised and used to label the signal probes. These nanohybrids have abundant active groups, and efficient redox and catalytic activity, allowing them to be used as the nanocarrier for a redox nanoprobe without the additional modification of electroactive substance and catalyst, which could effectively simplify the operation procedure and shorten the analysis time. With the catalysis of H2O2 by nanohybrids, the detection signal of N-G/PdPt/PANI itself could be significantly enhanced, lead to the improvement of the sensitivity. Under optimal conditions, the electrochemical DNA biosensor exhibited desirable performance for the determination of rs1801177 with a wide linearity ranging from 10 fM to 10nM and a relatively low detection limit of 3.33 fM (S/N=3). The proposed biosensor showed excellent selectivity to the target DNA compared to possible interfering substances. The results suggested that this method has potential applications in clinical research. PMID- 29175216 TI - Ultrasensitive electrochemiluminescence assay of tumor cells and evaluation of H2O2 on a paper-based closed-bipolar electrode by in-situ hybridization chain reaction amplification. AB - In this manuscript, a disposable paper-based analytical device comprised of a closed bipolar electrode (BPE) was fabricated for the ultrasensitive electrochemiluminescence (ECL) detection of intracellular H2O2 and the number of cancer cells. In this approach, wax printing was used to fabricated reaction zone, and carbon ink-based BPE and driving electrodes were screen-printed into the paper. AuPd nanoparticles (NPs), which served as a carrier of the capture aptamer and as the catalyst for the ECL reaction of luminol and H2O2, were used to modify the BPE. Luminol/Au NPs were attached to the surface of the captured cells via hybridation chain reaction with two hairpin structure DNA labelled luminol/Au NPs. In the stimulation of phorbol myristate acetate, The coreactant H2O2 was released from the target cells. The ECL response of the luminol-H2O2 system was related to the number of cancer cells in the testing buffer, which served as a quantitative signal for the determination of cancer cells and the concentration of H2O2. In order to decrease the external voltage, K3[Fe(CN)6] was introduced in the cathode resevoir of BPE because it gained electrons at the cathode more easily than oxygen. The ECL intensity was quantitatively related to the concentration of MCF-7 in the range of 1.0 * 102-1.0 * 107 cells/mL. The detection limit was 40 cells/mL and it showed good specificity for cells with high overexpression of mucin-1 receptor, it was concluded that the developed protocol could be effectively utilized for the detection of MCF-7 cells. PMID- 29175217 TI - Superwettable microchips with improved spot homogeneity toward sensitive biosensing. AB - The high-quality spots in microchips are prerequisites for sensitive and accurate detection of biomarkers. In this work, the superwettable micropattern was constructed by introducing superhydrophilic microwells onto a superhydrophobic substrate. The sample can distribute homogeneously within the well-designed superhydrophilic microwells after droplet evaporation and form homogeneous deposit spots, which can be ascribed to the enhanced Marangoni effect in superwettable micropattern and the suppressed outward flow by 3D nanodendritic silica structure. Based on the improved homogeneity of spots, sensitive and accurate fluorescence readout could be obtained. The free prostate-specific antigen (f-PSA) microchip based on the superwettable micropattern was developed. This superwettable f-PSA microchip exhibits high sensitivity, excellent specificity and long-term stability, and a limit of detection as low as 10fgmL-1 is achieved. Moreover, the superwettable f-PSA microchip can accurately detect human serum samples with excellent correlations with chemiluminescence immunoassay in the clinic, demonstrating its great potential as a sensitive and reliable sensing platform for biological analysis and clinical diagnosis. PMID- 29175218 TI - A multi-functional gold/iron-oxide nanoparticle-CNT hybrid nanomaterial as virus DNA sensing platform. AB - Nanoparticle (NP)-carbon nanomaterial hybrid structures have garnered significant attention due to their synergistic effects. Based on their interesting properties, hybrid nanomaterial-based sensing platforms have been investigated to achieve high sensitivity and selectivity detection. In our study, binary-NP decorated carbon nanotubes (bNP-CNTs) were successfully synthesized through a simple two-step method and applied as a biosensing platform. Gold (Au)/iron-oxide magnetic NP-decorated CNTs (Au/MNP-CNT) were used for influenza and norovirus DNA sensing channels. To demonstrate biosensing, first, the Au/MNP-CNTs were magnetically aligned on a Pt-interdigitated electrode, and then, a thiol-group functionalized probe DNA was attached to the Au NP surface on the bNP-CNT hybrid structure through thiol chemistry. DNA hybridization between the target influenza or norovirus DNA and probe DNA was measured to monitor an electrical conductivity change of the Au/MNP-CNTs. Various concentrations of target DNA from 1pM to 10nM were monitored, and the limits of detection for influenza virus and norovirus were calculated to be approximately 8.4pM and 8.8pM, respectively. The specificity was confirmed using different mismatched DNA sequences, showing high specificity. Therefore, this Au/MNP-CNT-based DNA sensing system exhibited excellent detection potential, and such hybrid materials could be universally applied as a highly sensitive and selective biosensing system. PMID- 29175219 TI - Effects of religiosity and religious coping on medication adherence and quality of life among people with epilepsy. AB - The epidemiologic information demonstrates the importance of caring people with epilepsy (PWE). Indeed, the impaired quality of life (QoL) and medication nonadherence rate among PWE have been reported. However, religiosity and religious coping could be potential factors for clinicians to foster appropriate intervention on epileptic care. This study investigated two models to further understand the relationships between religiosity, religious coping (including positive and negative coping), medication adherence, and QoL in an Iranian sample with epilepsy. Eligible PWE (n=760) completed the religiosity scale (Duke University Religion Index; DUREL) at baseline; the religious coping scale (Brief Religious Coping Scale; Brief RCOPE) one month later; the medication adherence scale (Medication Adherence Report Scale; MARS-5) two months later; and the QoL scale (Quality of Life in Epilepsy; QOLIE-31) twelve months later. Their antiepileptic drug serum level was measured during the period they completed the MARS. Through structural equation modeling (SEM), we found that religiosity directly correlated with negative religious coping and medication adherence, and indirectly correlated with medication adherence through negative religious coping. Both positive and negative religious coping directly correlated with medication adherence and QoL. Therefore, religiosity and religious coping may be determinants of medication adherence and QoL in PWE; health professionals may consider asking PWE if religion is important to them and how they use it to cope with their epilepsy. PMID- 29175220 TI - Periictal sign of the cross or Signum Crucis as a lateralizing sign in focal epilepsies: Not only a right temporal lobe epilepsy feature. AB - INTRODUCTION: The sign of the cross (SC) is a catholic ritual that has been described as an automatism during the ictal phase in patients with right temporal lobe epilepsy. OBJECTIVE: The study aimed to describe the prevalence of the SC and analyze the characteristics of patients who presented this phenomenon during the video-electroencephalography (VEEG) admission in our Epilepsy department. METHODS: This is a retrospective analysis of 1308 recorded seizures; 14 patients presented the SC during the admission. Seizure semiology, electroencephalography (EEG), etiology, neuroimaging, and surgical findings were analyzed. RESULTS: A prevalence of 1.1% was found, and the sign was not only an ictal finding (21% was postictal) but also exclusive of patients with temporal lobe epilepsy (15% were extratemporal) in contrast to what has been reported so far. The localizing and lateralizing value of the ictal SC was low (sensitivity 75%, specificity 33.3%, positive predictive value 60%, negative predictive value 50% for a right temporal epileptogenic zone (EZ)) compared with other previously described signs. Regardless of the lateralization of the EZ, the sign was always performed with the right hand supporting the hypothesis of a possible learned behavioral automatism. CONCLUSION: The SC is a rare ictal or postictal manifestation that occurs in patients with temporal and extratemporal epilepsies without clear localizing and lateralizing value compared with previously described signs. PMID- 29175221 TI - Epilepsy is a neurological and a systemic disorder. AB - The basic pathophysiology of epilepsy is still not fully understood. Epidemiological evidence for epilepsy seems to suggest that it may not only be the propensity for seizures to occur. The high prevalence of comorbidity and the finding that premature mortality is still increased in those who are in long-term remission, suggest that there is a systemic component to the condition. This systemic component is an additional shared risk factor that can explain an important proportion of the comorbidities of epilepsy as well as how an individual with inactive epilepsy remains at an elevated risk of premature mortality. This systemic component can be viewed from the perspective of a number of fundamental pathophysiological processes: inflammation, oxidative stress, glycation, and methylation capacity. These processes are associated with all cause mortality and there is also a growing understanding of their impact on seizure processes. We propose that epilepsy be considered as the sum of seizures and comorbidities caused by systemic dysfunction, and that the comprehensive management of epilepsy should also include the management of the systemic dysfunction. PMID- 29175222 TI - Temporal lobe asymmetry in FDG-PET uptake predicts neuropsychological and seizure outcomes after temporal lobectomy. AB - OBJECTIVE: The objective of this study was to determine whether preoperative [18F]fludeoxyglucose (FDG)-positron emission tomography (PET) asymmetry in temporal lobe metabolism predicts neuropsychological and seizure outcomes after temporal lobectomy (TL). METHODS: An archival sample of 47 adults with unilateral temporal lobe epilepsy who underwent TL of their language-dominant (29 left, 1 right) or nondominant (17 right) hemisphere were administered neuropsychological measures pre- and postoperatively. Post-TL seizure outcomes were measured at 1year. Regional FDG uptake values were defined by an automated technique, and a quantitative asymmetry index (AI) was calculated to represent the relative difference in the FDG uptake in the epileptic relative to the nonepileptic temporal lobe for four regions of interest: medial anterior temporal (MAT), lateral anterior temporal (LAT), medial posterior temporal (MPT), and lateral posterior temporal (LPT) cortices. RESULTS: In language-dominant TL, naming outcomes were predicted by FDG uptake asymmetry in the MAT (r=-0.38) and LPT (r= 0.45) regions. For all patients, visual search and motor speed outcomes were predicted by FDG uptake asymmetry in all temporal regions (MPT, r=0.42; MAT, r=0.34; LPT, r=0.47; LAT, r=0.51). Seizure outcomes were predicted by FDG uptake asymmetry in the MAT (r=0.36) and MPT (r=0.30) regions. In all of these significant associations, greater hypometabolism in regions of the epileptic temporal lobe was associated with better postoperative outcomes. CONCLUSIONS: Our results support the conclusion that FDG uptake asymmetry is a useful clinical tool in assessing risk for cognitive changes in patients being considered for TL. PMID- 29175223 TI - Implementation of a Mindfulness Moment Initiative for Healthcare Professionals: Perceptions of Facilitators. AB - CONTEXT: Mindfulness practices in the workplace have experienced rapid growth, with initial evidence suggesting positive outcomes. Even so, little is known about implementing mindfulness-based interventions (MBI), especially internally driven programs led by volunteers rather than experts. OBJECTIVE: This study qualitatively explores volunteer facilitators' perceptions of a short-dose MBI (the mindfulness moment initiative) before and 6 weeks after implementation. METHODS: Mindfulness moments were 1-3-minute-guided periods of mindfulness led at the beginning of various staff meetings at an inner-city community medical center. Facilitators' perceptions were collected through thirty-one 30-minute semi-structured interviews before and after the MMI's first 6 weeks. Categorizing and connecting strategies were employed to explore the emergence of themes and patterns across responses. RESULTS: Mindfulness moment facilitators interviewed before the intervention expected their groups to experience several intra- and interpersonal benefits. After implementation, they perceived all of these benefits to have occurred, but some benefits were mentioned more frequently before than after implementation and vice versa. Five of six expected obstacles were reported after implementation, with timing issues emerging as the most frequently mentioned theme. Facilitators believed that benefits outweighed obstacles. Our data also suggested that mindfulness moments may provide managers with an additional way to address moments of tension occurring between co workers. Most facilitators intended to continue leading mindfulness moments and wished to expand the practice to new departments. CONCLUSION: The mindfulness moment intervention may provide a way to bring mindfulness into organizations that is not dependent on formal training programs, a large time commitment, or a commitment to extended training. Prior knowledge of the obstacles and benefits found here may result in a more successful intervention. PMID- 29175224 TI - The Shock of Charlottesville: Unmasking Racism in Healthcare. PMID- 29175225 TI - 'Pastoral practices' for quality improvement in a Kenyan clinical network. AB - We explain social and organisational processes influencing health professionals in a Kenyan clinical network to implement a form of quality improvement (QI) into clinical practice, using the concept of 'pastoral practices'. Our qualitative empirical case study, conducted in 2015-16, shows the way practices constructing and linking local evidence-based guidelines and data collection processes provided a foundation for QI. Participation in these constructive practices gave network leaders pastoral status to then inscribe use of evidence and data into routine care, through championing, demonstrating, supporting and mentoring, with the support of a constellation of local champions. By arranging network meetings, in which the professional community discussed evidence, data, QI and professionalism, network leaders also facilitated the reconstruction of network members' collective professional identity. This consequently strengthened top down and lateral accountability and inspection practices, disciplining evidence and audit-based QI in local hospitals. By explaining pastoral practices in this way and setting, we contribute to theory about governmentality in health care and extend Foucauldian analysis of QI, clinical networks and governance into low and middle income health care contexts. PMID- 29175226 TI - What if the baby doesn't survive? Health-care decision making for ill newborns in Ethiopia. AB - Despite efforts to improve access to and quality of care for newborns, the first month after birth remains the most dangerous period of life. Given high neonatal mortality in low-income countries, saving newborn lives is a key priority for global and national health policy agendas. However, little is known about how these policies resonate with local understandings, experiences and household priorities. In this qualitative study we examined families' decision making and health-care-seeking in Butajira, Ethiopia. Data were collected through observation in hospital, in-depth interviews (41), and focus group discussions (7) with family members, health-care workers, and community members (October November 2015). Transcripts and field notes were analyzed inductively using qualitative content analysis. Findings indicate that newborn health was not always the family's priority. Local perceptions of newborns as not yet useful members of the household alongside costly health-care services delayed decision making and care-seeking. While sickness was recognized as dangerous for the ill newborn, seeking health-care could be harmful for the economic survival of the family. In a resource-constrained setting, families' focused on productive assets in order to minimize long-term risks, and waited before seeking newborn health care services. Until the baby had survived the first vulnerable weeks and months of life, the unknown newborn was not yet seen as a social person by the community. Personhood evolved progressively as the baby became a part of the family. A newborn death was surrounded by silence, and families received minimal support from traditional financial associations, iddirs. Decisions regarding health-care were contingent upon families' understandings of newborns and their resource-constrained circumstances. Improving newborn health involves recognizing why families choose to (not) seek health-care, and their actual opportunities and constraints in making such decisions. The everyday realities of vulnerable newborns must be at the center of global and national policy discussions and local implementation. PMID- 29175227 TI - Does Testosterone Treatment Increase Anger Expression in a Population of Transgender Men? AB - BACKGROUND: The acquisition of phenotypic male features in transmen with gender dysphoria requires testosterone treatment. The suppression of menses is 1 of the most desired effects. The relation between testosterone levels and human aggressive behavior has been described. However, the effects of testosterone on anger expression have been poorly investigated in trans-persons. AIM: To assess the effects of testosterone treatment on anger expression in transmen using a validated self-report questionnaire (Spielberger's State-Trait Anger Expression Inventory-2 [STAXI-2]). METHODS: 52 transmen diagnosed with gender dysphoria were evaluated before (T0) and at least 7 months after (T1) initiation of continuous gender-affirming testosterone treatment. Sociodemographic characteristics, anthropometric parameters, diagnosis of psychiatric disorders, current psychopharmacologic treatments, and life events were investigated at T0. OUTCOMES: STAXI-2 scores, serum testosterone, and estradiol levels at T0 and T1 were compared. RESULTS: Most of the sample (61.5%, n = 32) had no Axis I or II comorbidity. All subjects at T1 achieved significantly higher serum testosterone levels (5.67 +/- 3.88 ng/mL), whereas no significant difference in estradiol levels was observed from T0 to T1. At T1 only 46.2% (n = 24) of the sample achieved iatrogenic amenorrhea, whereas most of the sample had persistent regular bleedings. A significant increase in STAXI anger expression and anger control scores from T0 to T1 was recorded. Patients with persistent bleedings and Axis I disorders seemed to have higher odds of expressing anger. However, circulating testosterone levels at T1 did not influence anger expression. CLINICAL IMPLICATIONS: Interestingly, despite the increase of anger expression scores, during continuous testosterone treatment, there were no reports of aggressive behavior, self-harm, or psychiatric hospitalization. STRENGTHS AND LIMITATIONS: A limitation to this study is that although the STAXI-2 is a well-validated instrument measuring anger expression, it is a self-report psychometric measure. CONCLUSION: This study demonstrates that during 7 months of continuous gender affirming hormonal treatment, anger expression and anger arousal control increased in transmen. Persistence of menstrual bleedings and Axis I disorders, but not circulating testosterone levels, were predictive of the increase in anger expression score. Continuous psychological support to transmen during gender affirming hormonal treatment was useful to prevent angry behaviors and decrease the level of dysphoria.

AB - Public concern has been a catalyst for an emerging body of research investigating the potential long-term negative health consequences associated with sport related concussion and subconcussive impacts. We conducted a systematic review of the literature on mental health measures associated with sport-related brain injuries in former athletes. Ovid MEDLINE, EMBASE, CINAHL, and PsychINFO databases were used. Thirteen studies were included in the final review. We identified a consistent positive association between a history of concussion and depression among former athletes, although the underlying causation remains unclear. Limited and inconsistent findings were observed in studies that evaluated subconcussive impacts. Overall, several methodological shortcomings were noted, including selection bias, research design, operational definitions, and measurement tools. Future research will benefit from employing prospective longitudinal studies, surveillance data systems and standardized collection methods, and should attempt to account for psychosocial modifiers or confounders when reporting the mental health status of former athletes. This area would also benefit from studies that include equal representation of male and female athletes, examine mental health disorders beyond depression, and assess a variety of sports and competition levels. PMID- 29175228 TI - Porous silicon based photoluminescence immunosensor for rapid and highly sensitive detection of Ochratoxin A. AB - A rapid and low cost photoluminescence (PL) immunosensor for the determination of low concentrations of Ochratoxin A (OTA) has been developed. This immunosensor was based on porous silicon (PSi) and modified by antibodies against OTA (anti OTA). PSi layer was fabricated by metal-assisted chemical etching (MACE) procedure. Main structural parameters (pore size, layer thickness, morphology and nanograins size) and composition of PSi were investigated by means of X-Ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectroscopy. PL spectroscopy of PSi was performed at room temperature and showed a wide emission band centered at 680 +/- 20nm. Protein A was covalently immobilized on the surface of PSi, which in next steps was modified by anti-OTA and BSA in this way a anti-OTA/Protein-A/PSi structure sensitive towards OTA was designed. The anti OTA/Protein-A/PSi-based immunosensors were tested in a wide range of OTA concentrations from 0.001 upto 100ng/ml. Interaction of OTA with anti-OTA/Protein A/PSi surface resulted in the quenching of photoluminescence in comparison to bare PSi. The limit of detection (LOD) and the sensitivity range of anti OTA/Protein-A/PSi immunosensors were estimated. Association constant and Gibbs free energy for the interaction of anti-OTA/Protein-A/PSi with OTA were calculated and analyzed using the interaction isotherms. Response time of the anti-OTA/Protein-A/PSi-based immunosensor toward OTA was in the range of 500 700s. These findings are very promising for the development of highly sensitive, and potentially portable immunosensors suitable for fast determination of OTA in food and beverages.

AB - BACKGROUND: Respiratory syncytial virus (RSV) can be associated with severe disease and prolonged shedding in immunocompromised patients. OBJECTIVE: To investigate the genetic variability of RSV in consecutive samples of haematological patients with prolonged RSV shedding. STUDY DESIGN: Haematological patients at the University Hospital Heidelberg are routinely screened for respiratory viruses during winter season. In patients with prolonged RSV shedding between 2011 and 2014, Sanger-sequencing of the second hypervariable region of the RSV G gene was performed in consecutive samples. Further, deep-sequencing was performed in representative samples. RESULTS: Patients with prolonged RSV-A shedding were analysed (n=16, mean shedding 90days, 81.2% male). Phylogenetic analysis identified RSV genotypes NA1 (2011/12) or ON1 (2012/13). In most patients (n=12/16), Sanger-sequencing of the G gene showed identical sequences over the course of the shedding period. However, in two patients with particularly long viral shedding (333 and 142days), Sanger-sequencing revealed the presence of mutations leading to premature stop codons (37 and 70 amino acids truncated) in the G gene. In one additional patient, deep-sequencing revealed variants with premature stop codons at different positions. All three patients received repeatedly intravenous immunoglobulins. Interestingly, deep-sequencing revealed also a loss of the characteristic 72-nucleotide-duplication in all analysed ON1 strains. CONCLUSIONS: Long shedding periods and lack of immune selective pressure in the immunocompromised host seems to allow the persistence of viruses stripping a part of the C-terminus of the G glycoprotein. The loss of the characteristic 72-nucleotide-duplication in RSV-A ON1 variant strains is here described for the first time.

AB - BACKGROUND: We evaluated the field performance of a rapid point-of-care (POC) test for hepatitis B surface antigen (HBsAg) that could support decentralization and scale-up of hepatitis B virus (HBV) diagnosis in Africa. OBJECTIVE: To determine the field performance of the Determine HBsAg POC test for diagnosis of HBV co-infection among HIV patients in Zambia. STUDY DESIGN: Between 2013-2014, we screened HIV-infected adults for HBsAg at two urban clinics in Zambia. A subset were tested with the POC Determine HBsAg (Alere, USA) by finger prick in the clinic and HBsAg serology (Access2Analyzer, Beckman Coulter) at a reference laboratory. If either test was reactive, we determined HBV viral load (VL) and genotype. We described patient demographic and clinical characteristics (including liver fibrosis) and assessed the sensitivity, specificity, positive and negative predictive values (PPV and NPV) of the Determine test. In secondary analyses, we assessed sensitivity among patients with replicating HBV (i.e., VL>20 IU/ml) and with high HBV VL (i.e.,>20,000IU/ml). RESULTS: Among 412 participants with both HBsAg tests, median age was 34 years, 51% were women, and median CD4 was 208 cells/mm3. By serology, 66 (16%) were HBsAg-positive. Overall Determine had 87.9% sensitivity, 99.7% specificity, 98.3% PPV, and 97.7% NPV. Six of 8 patients with false negative results had undetectable HBV VL and no evidence of significant liver fibrosis. Test sensitivity was 95.9% among the 51 with replicating HBV and 100% among the 28 with high HBV VL. CONCLUSIONS: Determine HBsAg is a cheaper alternative HBV testing option compared to the gold standard ELISA and has high specificity and good sensitivity in the field among HIV infected individuals. PMID- 29175233 TI - Biological information systems: Evolution as cognition-based information management. AB - An alternative biological synthesis is presented that conceptualizes evolutionary biology as an epiphenomenon of integrated self-referential information management. Since all biological information has inherent ambiguity, the systematic assessment of information is required by living organisms to maintain self-identity and homeostatic equipoise in confrontation with environmental challenges. Through their self-referential attachment to information space, cells are the cornerstone of biological action. That individualized assessment of information space permits self-referential, self-organizing niche construction. That deployment of information and its subsequent selection enacted the dominant stable unicellular informational architectures whose biological expressions are the prokaryotic, archaeal, and eukaryotic unicellular forms. Multicellularity represents the collective appraisal of equivocal environmental information through a shared information space. This concerted action can be viewed as systematized information management to improve information quality for the maintenance of preferred homeostatic boundaries among the varied participants. When reiterated in successive scales, this same collaborative exchange of information yields macroscopic organisms as obligatory multicellular holobionts. Cognition-Based Evolution (CBE) upholds that assessment of information precedes biological action, and the deployment of information through integrative self referential niche construction and natural cellular engineering antecedes selection. Therefore, evolutionary biology can be framed as a complex reciprocating interactome that consists of the assessment, communication, deployment and management of information by self-referential organisms at multiple scales in continuous confrontation with environmental stresses.

PMID- 29175237 TI - Severity of Gastrointestinal Bleeding in Patients Treated with Direct-Acting Oral Anticoagulants. AB - BACKGROUND: Direct-acting oral anticoagulants (DOACs), which have gained approval for stroke prevention in nonvalvular atrial fibrillation and treatment of venous thromboembolism, have become increasingly preferred over warfarin given their predictable pharmacodynamics, lack of required monitoring, and superior outcomes. Direct-acting oral anticoagulants have been shown to be associated with an increased frequency of gastrointestinal bleeding compared with warfarin, but the severity and characteristics of gastrointestinal bleeding in these patients is poorly understood. METHODS: We retrospectively evaluated electronic medical records of patients with gastrointestinal bleeding (n = 8496) from 2010-2016. We identified 61 patients with gastrointestinal bleeding episodes while treated with DOACs (rivaroxaban, dabigatran, or apixaban) and 123 patients with gastrointestinal bleeding while taking warfarin. We randomly selected a control group of 296 patients with gastrointestinal bleeding who were not receiving anticoagulation treatment from the same sample. Outcomes included the need for hospitalization, blood transfusion, endoscopic or surgical intervention, and 30 day mortality. RESULTS: The DOAC and warfarin groups were similar in terms of age and underlying comorbidity (assessed using the Charlson Comorbidity Index), but the DOAC group had greater concomitant aspirin use. Gastrointestinal bleeding was classified as upper (n = 186), lower (n = 88), anorectal (n = 183), small bowel (n = 9), and indeterminate (n = 14). After adjusting for differences in baseline variables, the DOAC group had fewer hospitalizations and required fewer transfusions than the warfarin group. The DOAC and control groups were not statistically different for all outcomes. There were no significant mortality differences among groups. CONCLUSION: Although prior studies have shown a higher frequency of gastrointestinal bleeding in patients treated with DOACs compared with warfarin, our data suggest that gastrointestinal bleeding in patients taking DOACs may be less severe. These differences occurred despite significantly greater concomitant aspirin use in the DOAC group compared with warfarin users. PMID- 29175238 TI - Which Patent Foramen Ovales Need Closure to Prevent Cryptogenic Strokes? AB - Patients with cryptogenic strokes are more likely to have a patent foremen ovale than in the general population. It is speculated that these strokes are due to paradoxical embolism, that is, passage of a venous thrombus across the patent foremen ovale to enter the arterial circulation, resulting in an embolic stroke. Venous thromboembolism is rarely present in these cases of cryptogenic stroke. Thousands of patients with cryptogenic strokes have undergone transcatheter closure of their patent foremen ovale via a variety of devices. The first 3 randomized clinical trials comparing patent foremen ovale closure with medical therapy failed to show a significant advantage of patent foremen ovale closure. Three additional trials reported in 2017 had longer years of follow-up and demonstrated an advantage of patent foremen ovale closure versus medical therapy. Analysis of their data indicated that patent foremen ovale closure in patients with an atrial septal aneurysm in addition to a patent foremen ovale had a very significant decrease in cryptogenic strokes (P < .001). There was no decrease in strokes in patients without an aneurysm of the atrial septum who underwent patent foremen ovale closure (P = .37). Aneurysms of the atrial septum are easily recognized by echocardiography and are present in approximately one-third of patients with patent foremen ovales. These data suggest that closure of patent foremen ovales in patients with an atrial septal aneurysm is indicated. In patients with a patent foremen ovale without an aneurysm of the atrial septum, patent foremen ovale closure is not indicated.

PMID- 29175242 TI - Association of non-alcoholic steatohepatitis with subclinical myocardial dysfunction in non-cirrhotic patients. AB - BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is associated with increased cardiovascular risk. Among categories of NAFLD, hepatic fibrosis is most likely to affect mortality. Myocardial function and its energy metabolism are tightly linked, which might be altered by an insulin resistant condition such as NAFLD. We investigated whether hepatic steatosis and fibrosis were associated with myocardial dysfunction relative to myocardial glucose uptake. METHODS: A total of 308 patients (190 without NAFLD, 118 with NAFLD) were studied in a tertiary care hospital. Myocardial glucose uptake was evaluated at fasted state using [18F]-fluorodeoxyglucose-positron emission tomography (18FDG-PET). Hepatic steatosis and fibrosis were assessed by transient liver elastography (Fibroscan(r)) with controlled attenuation parameter, which quantifies hepatic fat and by surrogate indices (fatty liver index and NAFLD fibrosis score). Cardiac structure and function were examined by echocardiogram. RESULTS: Compared to those without NAFLD, patients with NAFLD had alterations in cardiac remodeling, manifested by increased left ventricular mass index, left ventricular end-diastolic diameter, and left atrial volume index (all p <0.05). Hepatic steatosis was significantly associated with left ventricular filling pressure (E/e' ratio), which reflects diastolic dysfunction (p for trend <0.05). Those without NAFLD were more likely to have higher myocardial glucose uptake compared to those with NAFLD. Significant hepatic fibrosis was also correlated with diastolic dysfunction and impaired myocardial glucose uptake. Using multivariable linear regression, E/e' ratio was independently associated with hepatic fibrosis (standardized beta = 0.12 to 0.27; all p <0.05). Association between hepatic steatosis and E/e' ratio was also significant (standardized beta = 0.10 to 0.15; all p <0.05 excluding the model adjusted for adiposity). CONCLUSIONS: Hepatic steatosis and fibrosis are significantly associated with diastolic heart dysfunction. This association is linked with myocardial glucose uptake evaluated by 18FDG-PET. LAY SUMMARY: Non-alcoholic fatty liver disease is associated with an increased risk of cardiovascular disease. More severe forms of non-alcoholic fatty liver disease, where hepatic fibrosis occurs, are linked to increased mortality. In this study, we have shown that hepatic steatosis and fibrosis are associated with subclinical myocardial dysfunction. This association is linked to altered myocardial glucose uptake. PMID- 29175243 TI - The molecular functions of hepatocyte nuclear factors - In and beyond the liver. AB - The hepatocyte nuclear factors (HNFs) namely HNF1alpha/beta, FOXA1/2/3, HNF4alpha/gamma and ONECUT1/2 are expressed in a variety of tissues and organs, including the liver, pancreas and kidney. The spatial and temporal manner of HNF expression regulates embryonic development and subsequently the development of multiple tissues during adulthood. Though the HNFs were initially identified individually based on their roles in the liver, numerous studies have now revealed that the HNFs cross-regulate one another and exhibit synergistic relationships in the regulation of tissue development and function. The complex HNF transcriptional regulatory networks have largely been elucidated in rodent models, but less so in human biological systems. Several heterozygous mutations in these HNFs were found to cause diseases in humans but not in rodents, suggesting clear species-specific differences in mutational mechanisms that remain to be uncovered. In this review, we compare and contrast the expression patterns of the HNFs, the HNF cross-regulatory networks and how these liver enriched transcription factors serve multiple functions in the liver and beyond, extending our focus to the pancreas and kidney. We also summarise the insights gained from both human and rodent studies of mutations in several HNFs that are known to lead to different disease conditions.

PMID- 29175245 TI - Characterization of two channel catfish, Ictalurus punctatus, glucocorticoid receptors and expression following an acute stressor. AB - Two channel catfish glucocorticoid receptor genes, ipGR1 (NR3C1_1) and ipGR2 (NR3C1_2) were partially characterized. Identification and analysis of the genomic organization of two channel catfish glucocorticoid (GC) receptors (GRs) revealed differences in the lengths of exons 1 and 2 and the addition of an extra 27-bp exon inserted after exon 2 in the GR1 gene, yielding a 9-aa insert in the receptor protein. Sequence of the 9-aa insert in ipGR1 (WRARQNTHG) is unique compared to other teleost fish GRs. Amino acid sequence alignment of the two channel catfish GRs, revealed 55% sequence identity between them, with a high degree of sequence conservation (82%) in the DNA binding and ligand binding domains. Real-time PCR indicated that ipGR1 and ipGR2 were expressed in all tissues evaluated. Channel catfish GR1 was predominantly expressed in the gills, nearly 25-fold higher than in the liver. GR1 expression was higher than GR2 expression in gills, intestine, head kidney and heart (P<0.05). Channel catfish hepatic GR1 mRNA expression was significantly (P<0.05) increased from pre-stress expression 30min following removal of the acute stressor. After 30min of stress and during the 2h recovery period, ipGR1 mRNA expression was higher relative to ipGR2 expression. Hepatic ipGR2 expression was not affected (P>0.05) by the acute stress event. The present study adds to the growing body of information on GR evolution and function and further demonstrates the unique regulation of the GC/GR system in teleost fish. PMID- 29175246 TI - Reply.

AB - BACKGROUND: Contraception counseling and provision is an essential preventative service. Real-time assessment of these services is critical for quality improvement and comparative study. Direct observation is not feasible on a large scale, so indirect measures (such as chart review) have been determined to be acceptable tools for this assessment. Computer-aided chart review has significant benefits over manual chart review as far as greater efficiency and ease of repeated measurements. The wide use of electronic medical records provides an opportunity to create a data extraction algorithm for computer-aided chart review that is sharable among institutions. We provide a useful schema for others who use electronic medical record systems and are interested in real-time assessment of contraception counseling and provision for the purposes of baseline assessment of services and quality improvement. OBJECTIVE: The purpose of this study was to create a comprehensive and accurate data extraction algorithm that is useful in the assessment of contraception counseling and provision rates in the outpatient setting. STUDY DESIGN: We included all visits between August 2015 and May 2016 at 8 outpatient clinics that are affiliated with a large, urban academic medical center in which nonpregnant women who were 14-45 years old were seen by a nurse practitioner, physician's assistant, or physician. Contraception-related prescriptions, International Classification of Diseases codes, current procedural terminology codes, and search-term capture were extracted with the use of structured query language from electronic medical record data that were stored in a relational database. The algorithm's hierarchy was designed to query prescription data first, followed by International Classification of Diseases and current procedural terminology codes, and finally search-term capture. Visits were censored when the first positive evidence of contraceptive service was obtained. Search terms were selected based on group discussion of investigators and providers. This algorithm was then compared with manual chart review and refined 3 times until high sensitivity and specificity, when compared with manual chart review, were achieved. RESULTS: There were 22,134 visits of reproductive aged women who our inclusion criteria. Electronic medical record evidence of contraception counseling or provision was found in 56.9% of these visits. Of these, 21.3% were captured by prescriptions; 8.9% were captured by International Classification of Diseases codes, and 69.7% were captured by search-term capture with the use of our algorithm. Among visits with evidence of contraception counseling without provision, 15.7% were captured by diagnosis codes and 84.3% were captured by search-term capture. When compared with manual chart review, sensitivity and specificity improved from 0.79 and 0.85 to 0.99 and 0.98, respectively, over the 3 rounds of testing and revision. CONCLUSION: Data extraction algorithms can be used effectively for computer-aided chart review of contraception counseling and provision measures, but testing and refinement are extremely important. Search-term capture from unstructured data is a critical component of a comprehensive algorithm, especially for the capture of instances of contraception counseling without provision. The algorithm that we developed here could be used by others with an electronic medical record system who are interested in real-time assessment, quality improvement, and comparative study of the delivery of contraceptive services. The ease of execution of this algorithm also allows for its repeated use for ongoing assessments over time. PMID- 29175249 TI - Reply.

AB - OBJECTIVE: to explore women's and midwives' expectations, knowledge and experiences of breastfeeding initiation using Social Cognitive Theory. DESIGN: a qualitative study using focus group discussions and individual interviews. Breastfeeding initiation was defined for this study as a process within the first 48hours after birth. Data were analysed using qualitative inductive analysis then further deductive analysis using Social Cognitive Theory (SCT). SETTING AND PARTICIPANTS: a purposefully selected sample of primigravid antenatal and postnatal women (n=18) and practising midwives (n=18) from one Health Board area in Scotland. FINDINGS: attachment of the baby to the breast at birth was hindered by sleepy babies and the busy unfamiliar hospital environment. These resulted in mothers struggling to maintain their motivation to breastfeed and to develop low self-efficacy. Instinctive attachment was rare. Midwives who considered it was normal for babies to be sleepy and unable to attach or feed at birth did not facilitate instinctive baby behaviour. Midwives sometimes experienced lack of autonomy and environmental circumstances that made women centred care difficult. Furthermore caring for high numbers of women, dependent on their help, resulted in reduced self-efficacy for providing effective breastfeeding support. KEY CONCLUSIONS: interviewing both women and midwives specifically about initiation of breastfeeding has allowed for deeper insights into this critical period and enabled a comparison between the data obtained from mothers and midwives. The findings suggest that instinctive attachment is not an expectation of either mothers or midwives and results in a loss of breastfeeding confidence in both. IMPLICATIONS FOR PRACTICE: to facilitate initiation there is a need for more research to develop appropriate maternal and midwifery skills, and make changes to the cultural environment in hospitals. Social Cognitive Theory could be used as a framework in both the antenatal and immediate postnatal period to develop strategies and materials to increase women's and midwives' self-efficacy specifically in initiation. PMID- 29175259 TI - Mechanical properties of milk sphingomyelin bilayer membranes in the gel phase: Effects of naturally complex heterogeneity, saturation and acyl chain length investigated on liposomes using AFM. AB - Sphingomyelin (SM) molecules are major lipid components of plasma membranes that are involved in functional domains. Among natural SMs, that found in milk (milk SM) exhibits important acyl chain heterogeneities in terms of length and saturation, which could affect the biophysical properties and biological functions of the milk fat globule membrane or of liposome carriers. In this study, the thermotropic and mechanical properties of milk-SM, synthetic C16:0-SM, C24:0-SM and the binary mixtures C16:0-SM/C24:0-SM (50:50% mol) and C24:0 SM/C24:1-SM (95:5% mol) bilayer membranes were investigated using differential scanning calorimetry and atomic force microscopy, respectively. Results showed that acyl chain length, heterogeneity and unsaturation affected i) the temperature of phase transition of SM bilayers, and ii) the mechanical properties of liposome (diameter<200nm) membranes in the gel phase, e.g. the Young modulus E and the bending rigidity kC. This study increases our knowledge about the key role of naturally complex lipid compositions in tailoring the physical properties of biological membranes. It could be also used in liposomes development e.g. to select the suitable lipid composition according to usage. PMID- 29175260 TI - Altered interferon-gamma expression in lymphocytes as a potential peripheral marker of chronic stress-induced cognitive deficit. AB - It is known that long-term exposure to stressful situations can produce severe consequences affecting behavioral, endocrine and immunological parameters. We have previously shown that stressed BALB/c mice had poor learning performance, which was reverted by glatiramer acetate treatment through a mechanism that likely involved the regulation of the cytokine balance and adult neurogenesis. In addition, recent results suggest that cytokine and neurotrophin expression in the hippocampus displayed similar tendencies as those in the serum. However, if lymphoid cells could be good candidates as peripheral markers of memory impairment have not yet been investigated. For this purpose, we analyzed the spatial memory and the neutrophin and cytokine mRNA levels in lymph nodes and hippocampus in mice submitted to chronic stress treated or not with glatiramer acetate. Results indicated that there was a correlation between the cytokine and neurotrophin mRNA levels in the hippocampus and in the peripheral lymph nodes, and the cognitive performance in BALB/c mice. In particular, our results suggest that altered IFN-gamma levels could be used as peripheral biomarker of cognitive deficit and treatment response. PMID- 29175261 TI - Th17 cytokine profiling of colorectal cancer patients with or without enterovirus 71 antigen expression. AB - OBJECT: Th17 cytokines have been identified in several types of human cancers. In this pilot study, the expression of Th17 cytokines profiling in enteroviruses 71 (EV71) associated colorectal cancer (CRC) were explored. METHODS: 66 patients with CRC were enrolled in this study; immune- histochemical analyses were performed on cancerous tissues and adjacent non- cancerous tissues of the patients. Serum Th17 cytokines of CRC patients and healthy controls were measured using a Luminex 200 analyzer. RESULTS: Cancerous tissues had more positive EV71 antigen expression than adjacent non- cancerous tissues. In TNM II-III CRC, 59.9% of cancerous tissues were observed to be EV71 positive; on the contrary, 65.2% of the adjacent non- cancerous epithelium was EV71 negative. In TNM I CRC, all adjacent non- cancerous epithelium was virus negative, but in TNM IV, half of adjacent non- cancerous tissues were virus positive. Serum IL-10 were significantly higher in CRC patients than in healthy controls, and IL-10 concentrations in the EV71 positive group were higher than those of the EV71 negative group, with the highest IL-10 levels being observed in CRC patients with strong positive group (P < 0.05). Similar results were found for IL-21 and IL-23. IL-17 levels were higher in CRC patients than in healthy controls, there was no significant difference in IL-17 between the viral positive and viral negative groups (P > 0.05). CONCLUSION: Persistent existing EV71 viral antigens in intestinal tissues are positively associated with TNM III/IV CRC. EV71 latent infection recruits Th17 cells in the colorectal tumor site, stimulating Th17 cytokine production that closely associated with CRC carcinogenesis. PMID- 29175262 TI - Gestational and Postnatal Cortisol Profiles of Women With Posttraumatic Stress Disorder and the Dissociative Subtype. AB - OBJECTIVE: To test the hypothesis that women with posttraumatic stress disorder (PTSD) have greater salivary cortisol levels across the diurnal curve and throughout gestation, birth, and the postpartum period than women who do not have PTSD. DESIGN: Prospective, longitudinal, biobehavioral cohort study. SETTING: Prenatal clinics at academic health centers in the Midwest region of the United States. PARTICIPANTS: Women expecting their first infants who fit with one of four cohorts: a nonexposed control group, a trauma-exposed control group, a group with PTSD, and a group with the dissociative subtype of PTSD. METHODS: In the first half of pregnancy, 395 women provided three salivary cortisol specimens on a single day for diurnal data. A subsample of 111 women provided three salivary cortisol specimens per day, 12 times, from early pregnancy to 6 weeks postpartum for longitudinal data. Trauma history, PTSD, and dissociative symptoms were measured via standardized telephone diagnostic interviews with the use of validated epidemiologic measures. Generalized estimating equations were used to determine group differences. RESULTS: Generalized estimating equations showed that women with the dissociative subtype of PTSD had the highest and flattest gestational cortisol level curves. The difference was greatest in early pregnancy, when participants in the dissociative subtype group had cortisol levels 8 times greater in the afternoon and 10 times greater at bedtime than those in the nonexposed control group. CONCLUSION: Women with the dissociative subtype of PTSD, a complex form associated with a history of childhood maltreatment, may have toxic levels of cortisol that contribute to intergenerational patterns of adverse health outcomes. PMID- 29175263 TI - Missing data and chance variation in public reporting of cancer stage at diagnosis: Cross-sectional analysis of population-based data in England. AB - BACKGROUND: The percentage of cancer patients diagnosed at an early stage is reported publicly for geographically-defined populations corresponding to healthcare commissioning organisations in England, and linked to pay-for performance targets. Given that stage is incompletely recorded, we investigated the extent to which this indicator reflects underlying organisational differences rather than differences in stage completeness and chance variation. METHODS: We used population-based data on patients diagnosed with one of ten cancer sites in 2013 (bladder, breast, colorectal, endometrial, lung, ovarian, prostate, renal, NHL, and melanoma). We assessed the degree of bias in CCG (Clinical Commissioning Group) indicators introduced by missing-is-late and complete-case specifications compared with an imputed 'gold standard'. We estimated the Spearman-Brown (organisation-level) reliability of the complete-case specification. We assessed probable misclassification rates against current pay-for-performance targets. RESULTS: Under the missing-is-late approach, bias in estimated CCG percentage of tumours diagnosed at an early stage ranged from -2 to -30 percentage points, while bias under the complete-case approach ranged from -2 to +7 percentage points. Using an annual reporting period, indicators based on the least biased complete-case approach would have poor reliability, misclassifying 27/209 (13%) CCGs against a pay-for-performance target in current use; only half (53%) of CCGs apparently exceeding the target would be correctly classified in terms of their underlying performance. CONCLUSIONS: Current public reporting schemes for cancer stage at diagnosis in England should use a complete-case specification (i.e. the number of staged cases forming the denominator) and be based on three-year reporting periods. Early stage indicators for the studied geographies should not be used in pay-for-performance schemes. PMID- 29175264 TI - New methodologies to accurately assess circulating active transforming growth factor-beta1 levels: implications for evaluating heart failure and the impact of left ventricular assist devices. AB - Transforming growth factor-beta1 (TGF-beta1) has been used as a biomarker in disorders associated with pathologic fibrosis. However, plasma TGF-beta1 assessment is confounded by the significant variation in reported normal values, likely reflecting variable release of the large pool of platelet TGF-beta1 after blood drawing. Moreover, current assays measure only total TGF-beta1, which is dominated by the latent form of TGF-beta1 rather than the biologically active form. To address these challenges, we developed methodologies to prevent ex vivo release of TGF-beta1 and to quantify active TGF-beta1. We then used these techniques to measure TGF-beta1 in healthy controls and patients with heart failure (HF) before and after insertion of left ventricular assist devices (LVAD). Total plasma TGF-beta1 was 1.0 +/- 0.60 ng/mL in controls and 3.76 +/- 1.55 ng/mL in subjects with HF (P < 0.001), rising to 5.2 +/- 2.3 ng/mL following LVAD placement (P = 0.006). These results were paralleled by the active TGF-beta1 values; controls had 3-16 pg/mL active TGF-beta1, whereas levels were 2.7-fold higher in patients with HF before, and 4.2-fold higher after, LVAD implantation. Total TGF-beta1 correlated with levels of the platelet-derived protein thrombospondin-1 (r = 0.87; P < 0.001), suggesting that plasma TGF-beta1 may serve as a surrogate indicator of in vivo platelet activation. von Willebrand factor high molecular weight multimers correlated inversely with TGF-beta1 levels (r = -0.63; P = 0.023), suggesting a role for shear forces in loss of these multimers and platelet activation. In conclusion, accurate assessment of circulating TGF-beta1 may provide a valuable biomarker for in vivo platelet activation and thrombotic disorders. PMID- 29175265 TI - Digital image analysis in breast pathology-from image processing techniques to artificial intelligence. AB - Breast cancer is the most common malignant disease in women worldwide. In recent decades, earlier diagnosis and better adjuvant therapy have substantially improved patient outcome. Diagnosis by histopathology has proven to be instrumental to guide breast cancer treatment, but new challenges have emerged as our increasing understanding of cancer over the years has revealed its complex nature. As patient demand for personalized breast cancer therapy grows, we face an urgent need for more precise biomarker assessment and more accurate histopathologic breast cancer diagnosis to make better therapy decisions. The digitization of pathology data has opened the door to faster, more reproducible, and more precise diagnoses through computerized image analysis. Software to assist diagnostic breast pathology through image processing techniques have been around for years. But recent breakthroughs in artificial intelligence (AI) promise to fundamentally change the way we detect and treat breast cancer in the near future. Machine learning, a subfield of AI that applies statistical methods to learn from data, has seen an explosion of interest in recent years because of its ability to recognize patterns in data with less need for human instruction. One technique in particular, known as deep learning, has produced groundbreaking results in many important problems including image classification and speech recognition. In this review, we will cover the use of AI and deep learning in diagnostic breast pathology, and other recent developments in digital image analysis.

In this review, we explore the emerging role of tumor necrosis factor receptor-associated factor 6 (TRAF6)-nuclear factor kappa B (NF kappaB) signaling axis in atherosclerosis, ischemic heart disease, pathologic cardiac hypertrophy or heart failure, myocarditis, and sepsis-induced cardiomyopathy. We discuss the current understanding of cardiac inflammation in heart disease, present the TRAF6 signaling axis in the heart, then summarize what is known about TRAF6 in pathophysiology of heart disease including proof-of concept studies that identify the utility of blocking TRAF6 to attenuate cardiac dysfunction, which suggests that TRAF6 is a novel, druggable target in treating cardiovascular disease incurred by inflammatory processes. PMID- 29175269 TI - Sclerostin deficiency modifies the development of CKD-MBD in mice. AB - : Sclerostin is a soluble antagonist of canonical Wnt signaling and a strong inhibitor of bone formation. We present experimental data on the role of sclerostin in chronic kidney disease - bone mineral disorder (CKD-MBD). METHODS: We performed 5/6 nephrectomies in 36-week-old sclerostin-deficient (SOST-/-) B6 mice and in C57BL/6J wildtype (WT) mice. Animals received a high phosphate diet for 11weeks. The bones were analyzed by high-resolution micro-computed tomography (MUCT) and quantitative bone histomorphometry. Aortic tissue was analyzed regarding the extent of vascular calcification. RESULTS: All nephrectomized mice had severe renal failure, and parathyroid hormone was highly increased compared to corresponding sham animals. All SOST-/- animals revealed the expected high bone mass phenotype. Overall, the bone compartment in WT and SOST-/- mice responded similarly to nephrectomy. In uremic WT animals, MUCT data at both the distal femur and lumbar spine revealed significantly increased trabecular volume compared to non-uremic WTs. In SOST-/- mice, the differences between trabecular bone volume were less pronounced when comparing uremic with sham animals. Cortical thickness and cortical bone density at the distal femur decreased significantly and comparably in both genotypes after 5/6 nephrectomy compared to sham animals (cortical bone density -18% and cortical thickness -32%). Overall, 5/6 nephrectomy and concomitant hyperparathyroidism led to a genotype-independent loss of cortical bone volume and density. Overt vascular calcification was not detectable in either of the genotypes. CONCLUSION: Renal osteodystrophy changes were more pronounced in WT mice than in SOST-/- mice. The high bone mass phenotype of sclerostin deficiency was detectable also in the setting of chronic renal failure with severe secondary hyperparathyroidism. PMID- 29175268 TI - Peripheral vascular atherosclerosis in a novel PCSK9 gain-of-function mutant Ossabaw miniature pig model. AB - Hypercholesterolemia is a major risk factor for atherosclerosis. Remaining challenges in the management of atherosclerosis necessitate development of animal models that mimic human pathophysiology. We characterized a novel mutant pig model with DNA transposition of D374Y gain-of-function (GOF) cDNA of chimp proprotein convertase subtilisin/kexin type-9 (PCSK9), and tested the hypothesis that it would develop peripheral vascular remodeling and target organ injury in the kidney. Wild-type or PCSK9-GOF Ossabaw miniature pigs fed a standard or atherogenic diet (AD) (n = 7 each) were studied in vivo after 3 and 6 months of diet. Single-kidney hemodynamics and function were studied using multidetector computed tomography and kidney oxygenation by blood oxygen level-dependent magnetic resonance imaging. The renal artery was evaluated by intravascular ultrasound, aortic stiffness by multidetector computed tomography, and kidney stiffness by magnetic resonance elastography. Subsequent ex vivo studies included the renal artery endothelial function and morphology of abdominal aorta, renal, and femoral arteries by histology. Compared with wild type, PCSK9-GOF pigs had elevated cholesterol, triglyceride, and blood pressure levels at 3 and 6 months. Kidney stiffness increased in GOF groups, but aortic stiffness only in GOF-AD. Hypoxia, intrarenal fat deposition, oxidative stress, and fibrosis were observed in both GOF groups, whereas kidney function remained unchanged. Peripheral arteries in GOF groups showed medial thickening and development of atheromatous plaques. Renal endothelial function was impaired only in GOF-AD. Therefore, the PCSK9-GOF mutation induces rapid development of atherosclerosis in peripheral vessels of Ossabaw pigs, which is exacerbated by a high-cholesterol diet. This model may be useful for preclinical studies of atherosclerosis. PMID- 29175270 TI - Prevalence of pelvic Paget's disease of bone in France. PMID- 29175267 TI - The role of macrophage phenotype in regulating the response to radiation therapy. AB - Increasing experimental and clinical evidence has revealed a critical role for myeloid cells in the development and progression of cancer. The ability of monocytes and macrophages to regulate inflammation allows them to manipulate the tumor microenvironment to support the growth and development of malignant cells. Recent studies have shown that macrophages can exist in several functional states depending on the microenvironment they encounter in the tissue. These functional phenotypes influence not only the genesis and propagation of tumors, but also the efficacy of cancer therapies, particularly radiation. Early classification of the macrophage phenotypes, or "polarization states," identified 2 major states, M1 and M2, that have cytotoxic and wound repair capacity, respectively. In the context of tumors, classically activated or M1 macrophages driven by interferon gamma support antitumor immunity while alternatively activated or M2 macrophages generated in part from interleukin-4 exposure hinder antitumor immunity by suppressing cytotoxic responses against a tumor. In this review, we discuss the role that the functional phenotype of a macrophage population plays in tumor development. We will then focus specifically on how macrophages and myeloid cells regulate the tumor response to radiation therapy. PMID- 29175272 TI - Fibrodysplasia ossificans progressiva in China. AB - Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare and devastating disorder characterized by cumulative episodes of progressive heterotopic ossification. It is estimated that there exist 600-700 patients in Mainland China. Nevertheless, due to the rarity, many FOP patients were initially misdiagnosed. Until now fewer than 150 patients have been identified in Mainland China. This review summarizes the epidemiology and clinical features of FOP patients, the progress of clinical and basic research in China, and the future of FOP care in China. PMID- 29175271 TI - Gnathodiaphyseal dysplasia: Severe atypical presentation with novel heterozygous mutation of the anoctamin gene (ANO5). AB - Gnathodiaphyseal dysplasia (GDD; OMIM #166260) is an ultra-rare autosomal dominant disorder caused by heterozygous mutation in the anoctamin 5 (ANO5) gene and features fibro-osseous lesions of the jawbones, bone fragility with recurrent fractures, and bowing/sclerosis of tubular bones. The physiologic role of ANO5 is unknown. We report a 5-year-old boy with a seemingly atypical and especially severe presentation of GDD and unique ANO5 mutation. Severe osteopenia was associated with prenatal femoral fractures, recurrent postnatal fractures, and progressive bilateral enlargement of his maxilla and mandible beginning at ~2months-of-age that interfered with feeding and speech and required four debulking operations. Histopathological analysis revealed benign fibro-osseous lesions resembling cemento-ossifying fibromas of the jaw without psammomatoid bodies. A novel, de novo, heterozygous, missense mutation was identified in exon 15 of ANO5 (c.1553G>A; p.Gly518Glu). Our findings broaden the phenotypic and molecular spectra of GDD. Fractures early in life with progressive facial swelling are key features. We assessed his response to a total of 7 pamidronate infusions commencing at age 15months. Additional reports must further elucidate the phenotype, explore any genotype-phenotype correlation, and evaluate treatments. PMID- 29175273 TI - Nitrate removal from pharmaceutical wastewater using microbial electrochemical system supplied through low frequency-low voltage alternating electric current. AB - In this study, a microbial electrochemical system (MES) was designed to evaluate the effects of a low frequency-low voltage alternating electrical current on denitrification efficacy in the presence of ibuprofen as a low biodegradable organic carbon source. Cylindrical carbon cloth and stainless steel mesh electrodes containing a consortium of heterotrophic and autotrophic bacteria were mounted in the wall of the designed laboratory-scale bioreactor. The effects of inlet nitrate concentration (50-800mgL-1), retention time (2.5-24h), waveform magnitude (0.1-9.6Vp-p), adjustable direct current voltage added to offset voltage (0.1-4.9V), alternating current frequency (10-60Hz), and waveforms (sinusoidal, square, and ramp) were studied in this work. The results showed that the proposed system removes 800mgL-1 nitrate up to 95% during 6.5h. Optimum conditions were obtained in the 8Vp-p using a frequency of 10Hz of a sinusoidal waveform. The morphology studies confirmed bacterial morphology change when applying the alternating current. Dehydrogenase activity of biofilms formed on surface of stainless steel electrodes increased to 15.24MUgTFmgbiomasscm-2d. The maximum bacterial activity was obtained at a voltage of 8Vp-p. The experimental results revealed that the MES using a low frequency-low voltage alternating electrical current is a promising technique for nitrate removal from pharmaceutical wastewaters in the presence of low biodegradability of carbon sources such as ibuprofen. PMID- 29175274 TI - Provision of menstrual regulation with medication among pharmacies in three municipal districts of Bangladesh: a situation analysis. AB - OBJECTIVE: The objective was to assess the provision of the combination of mifepristone-misoprostol for menstrual regulation (MR) in randomly selected urban pharmacies in Bangladesh. STUDY DESIGN: We conducted a cross-sectional survey among 553 pharmacy workers followed by 548 mystery client visits to the same pharmacies in 3 municipal districts during July 2014-December 2015. RESULTS: The survey found that 99% of pharmacy workers visited had knowledge of MR procedures but only two-thirds (67%) could state the legal time limit correctly; they mentioned misoprostol (86%) over mifepristone-misoprostol combination (78%) as a procedure of MR with medication (MRM); 36% reported knowing the recommended dosage of mifepristone-misoprostol combination; 70% reported providing information on effectiveness of the medicines; 50% reported recommending at least one follow-up visit to them; 63% reported explaining possible complications of using the medications; and 47% reported offering any post-MR contraception to their clients. In contrast, mystery client visits found that the mifepristone misoprostol combination (69%) was suggested over misoprostol (51%) by the pharmacy workers; 54% provided the recommended dosage of mifepristone-misoprostol combination; 42% provided information on its effectiveness; 12% recommended at least one follow-up visit; 11% counseled on possible complications; and only 5% offered post-MR contraceptives to the mystery clients. CONCLUSIONS: We found knowledge gaps regarding recommended dosage for MRM and inconsistent practice in informing women on effectiveness, follow-up visits, possible complications and provision of post-MR contraceptives among the pharmacy workers, particularly during the mystery client visits. IMPLICATIONS: Pharmacy workers in Bangladesh need to be trained on legal time limits for MR services provision, on providing accurate information on disbursed medicine, and on proper referral mechanisms. A strong monitoring and regulatory system for pharmacy provision of MRM in pharmacies should be established. PMID- 29175275 TI - Understanding AVATAR therapy: who, or what, is changing? PMID- 29175276 TI - AVATAR therapy for auditory verbal hallucinations in people with psychosis: a single-blind, randomised controlled trial. AB - BACKGROUND: A quarter of people with psychotic conditions experience persistent auditory verbal hallucinations, despite treatment. AVATAR therapy (invented by Julian Leff in 2008) is a new approach in which people who hear voices have a dialogue with a digital representation (avatar) of their presumed persecutor, voiced by the therapist so that the avatar responds by becoming less hostile and concedes power over the course of therapy. We aimed to investigate the effect of AVATAR therapy on auditory verbal hallucinations, compared with a supportive counselling control condition. METHODS: We did this single-blind, randomised controlled trial at a single clinical location (South London and Maudsley NHS Trust). Participants were aged 18 to 65 years, had a clinical diagnosis of a schizophrenia spectrum (ICD10 F20-29) or affective disorder (F30-39 with psychotic symptoms), and had enduring auditory verbal hallucinations during the previous 12 months, despite continued treatment. Participants were randomly assigned (1:1) to receive AVATAR therapy or supportive counselling with randomised permuted blocks (block size randomly varying between two and six). Assessments were done at baseline, 12 weeks, and 24 weeks, by research assessors who were masked to therapy allocation. The primary outcome was reduction in auditory verbal hallucinations at 12 weeks, measured by total score on the Psychotic Symptoms Rating Scales Auditory Hallucinations (PSYRATS-AH). Analysis was by intention-to-treat with linear mixed models. The trial was prospectively registered with the ISRCTN registry, number 65314790. FINDINGS: Between Nov 1, 2013, and Jan 28, 2016, 394 people were referred to the study, of whom 369 were assessed for eligibility. Of these people, 150 were eligible and were randomly assigned to receive either AVATAR therapy (n=75) or supportive counselling (n=75). 124 (83%) met the primary outcome. The reduction in PSYRATS-AH total score at 12 weeks was significantly greater for AVATAR therapy than for supportive counselling (mean difference -3.82 [SE 1.47], 95% CI -6.70 to -0.94; p<0.0093). There was no evidence of any adverse events attributable to either therapy. INTERPRETATION: To our knowledge, this is the first powered, randomised controlled trial of AVATAR therapy. This brief, targeted therapy was more effective after 12 weeks of treatment than was supportive counselling in reducing the severity of persistent auditory verbal hallucinations, with a large effect size. Future multi-centre studies are needed to establish the effectiveness of AVATAR therapy and, if proven effective, we think it should become an option in the psychological treatment of auditory verbal hallucinations.

AB - Increasingly recognized as a distinct form of childhood maltreatment, children's exposure to intimate partner violence (IPV) has been shown to be associated with an array of negative psychosocial outcomes, including elevated risk for additional violence over the life course. Although studies have identified child exposure to IPV as a predictor of IPV perpetration in adulthood, no review has critically evaluated the methodology of this quantitative work. The present study examines the association between childhood exposure to IPV and the perpetration of IPV in adulthood based on a systematic review of the literature from inception to January 4, 2016. Databases searched included Medline, Embase, PsycINFO, CINAHL, Cochrane Database of Systematic Reviews, Sociological Abstracts and ERIC. Database searches were complemented with backward and forward citation chaining. Studies were critically appraised using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Of 5601 articles identified by the search, 19 studies were included for data extraction. Sixteen of these studies found that child exposure to IPV was significantly and positively associated with adult IPV perpetration; three studies reported null findings. The methodological quality of the studies was low. Work thus far has tended to focus on child exposure to physical IPV and the perpetration of physical IPV within heterosexual contexts. In addition, measures of child exposure to IPV vary in their classification of what exposure entails. We critically discuss the strengths and limitations of the existing evidence and the theoretical frameworks informing this work. PMID- 29175278 TI - Animal cruelty as an indicator of family trauma: Using adverse childhood experiences to look beyond child abuse and domestic violence. AB - Youth who engage in animal cruelty are known to be at increased risk of perpetrating violence on other people in their lives including peers, loved ones, and elder family members. These youths have often been exposed to family violence, including animal cruelty perpetrated on their beloved pets by violent adults. The current study utilizes a data set of 81,000 juvenile offenders whose adverse childhood experiences are known and includes 466 youth who self-report engaging in animal cruelty. Compared to the larger group of juvenile offenders, the children admitting to engaging in animal cruelty are younger at time of first arrest, more likely to be male, and more likely to be White. When looking at their reports of adverse childhood experiences (ACEs), they are more likely than other juvenile offenders to have an array of adverse experiences beyond family violence and to have four or more ACEs. Although the youth who are cruel to animals are already troubled, the fact that they present to law enforcement at early ages provides early opportunities for intervention. Service providers outside the law enforcement field, such as teachers, physicians, veterinarians and animal control officers may be able to identify these vulnerable youth, and refer them to needed services before violence is visited on other humans. PMID- 29175279 TI - Genetic screening in two Iranian families with early-onset Alzheimer's disease identified a novel PSEN1 mutation. AB - A subset of early-onset Alzheimer's disease is inherited as an autosomal-dominant trait and is associated with mutations in the genes encoding beta-amyloid precursor protein, presenilin 1, or presenilin 2. In this study, we identified 2 PSEN1 mutations (1 novel and 1 known) in 2 unrelated Iranian families with autosomal-dominant Alzheimer's disease. The disease progressed rapidly with a mean age at onset of 33 and 42 years and an age at death ranging from 43 to 48 years. PMID- 29175280 TI - Surfing as a risk factor for sensitization to poly(gamma-glutamic acid) in fermented soybeans, natto, allergy. AB - BACKGROUND: Poly(gamma-glutamic acid) (PGA) is an allergen in natto, fermented soybeans, which causes late-onset anaphylaxis. We hypothesized that jellyfish stings sensitize adults to PGA because a surfer had allergies to both natto and jellyfish, whose sting contains PGA. The aim of the study was to identify behavioral factors, such as marine sports, associated with PGA sensitization. METHODS: Outpatients diagnosed with food allergies based on relevant clinical history, positive skin test and/or food challenge test answered a questionnaire during a regular visit in 2016. RESULTS: Questionnaire data from 140 outpatients were analyzed. These patients were divided into two groups: natto allergy group (13 patients, M:F = 10:3, mean age 40.6 years) and non-natto allergy group (127 patients, M:F = 46:81, mean age 44.5 years). All patients with natto allergy had positive results in skin prick test and basophil activation test with PGA. Of these, 92.3% had a marine sport hobby, especially surfing (84.6%). PGA sensitization was independently associated with marine sports (odds ratio, 278.0, 95 percent confidence interval, 36.9-6315.9, p < 0.001) adjusted for male sex and sea bathing, but not with male sex or sea bathing. In addition, although there was no significant difference in the experience of marine sports between natto and non-natto allergy groups, the natto allergy group participated significantly more frequently in marine sports than the non-natto allergy group (p < 0.001). There was no significant difference between natto consumption amount and PGA sensitization. CONCLUSIONS: Surfing is a risk factor for PGA sensitization in those with allergy to natto. PMID- 29175281 TI - Predicting Survival in Patients With Heart Failure With an Implantable Cardioverter Defibrillator: The Heart Failure Meta-Score. AB - BACKGROUND: Prognostic evaluation in heart failure (HF) is important to predict future events and decide timely management. Many HF patients are treated with the use of an implantable cardioverter-defibrillator (ICD). This study aimed to validate a meta-analytically derived prognostic score to predict survival in ICD HF patients. METHODS AND RESULTS: The HF Meta-score includes 14 independent mortality predictors identified in a meta-analysis, including age, sex, ethnicity, diabetes, chronic obstructive pulmonary disease, peripheral vascular disease, atrial fibrillation, ischemic cardiomyopathy, history of HF admission, New York Heart Association functional class, left ventricular ejection fraction, renal function, QRS duration, secondary prevention indication, and ICD shocks. The HF Meta-score performance was evaluated in comparison with the Seattle Heart Failure Model (SHFM) and the SHOCKED predictors in a cohort of 9860 ambulatory ICD patients from the Ontario provincial database for 2007-2011. During 3-year follow-up, 1816 patients died. The HF Meta-score showed excellent calibration, very good discrimination (c-statistic 0.74) and enhanced risk classification compared with the SHOCKED predictors, with better reclassifying in 19% and 56% of patients for 1- and 3-year survival, respectively. HF Meta-score performance was similar to the SHFM. CONCLUSIONS: The HF Meta-score is an evidence-based derived model that provides an accurate prognosis assessment in HF patients with ICDs. Its development strategy permits further incorporation of new predictors when evidence becomes available.

PMID- 29175283 TI - Influence of continuous positive airway pressure on postoperative leakage in bariatric surgery. AB - BACKGROUND: Obstructive sleep apnea (OSA) affects two third of morbidly obese individuals undergoing bariatric surgery. Perioperative usage of continuous positive airway pressure (CPAP) is advised for moderately and severe OSA to avoid respiratory failure and cardiac events. CPAP increases the air pressure in the upper airway, but also may elevate the air pressure in the esophagus and stomach. Concern exists that this predisposes to mechanical stress resulting in suture or staple line disruption (further referred to as suture line disruption). OBJECTIVES: To evaluate whether perioperative CPAP usage is associated with an increased risk of suture line disruption after bariatric surgery. SETTING: Obesity Center Amsterdam, OLVG-west, Amsterdam, the Netherlands. METHODS: All patients who underwent bariatric surgery including a suture line were eligible for inclusion. Only patients with information regarding OSA severity as defined by the apnea-hypopnea-index and postoperative CPAP usage were included. RESULTS: From November 2007 to August 2016, postoperative CPAP status was documented in 2135 patients: 497 (23.3%) used CPAP postoperatively, whereas 1638 (76.7%) used no CPAP. Mean body mass index was 44.1 kg/m2 (standard deviation 6.6). Suture line disruption occurred in 25 patients (1.2%). The leakage rate was not associated with CPAP usage (8 [1.6%] in CPAP group versus 17 [1%] in non-CPAP group, P = .300). CPAP was no risk factor for suture line disruption in multivariable analysis as well. CONCLUSION: Postoperative CPAP does not appear to increase the risk of suture line disruption in bariatric surgery. CPAP is recommended in all patients with moderate or severe OSA who undergo bariatric surgery. PMID- 29175284 TI - Increased Risk of Vitiligo Following Anti-Tumor Necrosis Factor Therapy: A 10 Year Population-Based Cohort Study. AB - Anti-tumor necrosis factor-alpha (anti-TNF) therapy is used to treat a wide range of chronic inflammatory conditions. However, there has been an increasing number of reports of development of vitiligo and alopecia areata secondary to anti-TNF therapy. In this study, we investigated the risks of vitiligo and alopecia areata in patients with ankylosing spondylitis, Crohn's disease, or ulcerative colitis, who were treated with or without anti-TNF therapy using data from the Korean National Health Insurance Claims database from 2007 to 2016. The study comprised 11,442 patients treated with anti-TNF agents (anti-TNF group), and an equal number of age-, sex-, and disease- matched patients treated without anti-TNF agents (unexposed group). Multivariable Cox proportional hazards models were used to compare the risks of vitiligo and alopecia areata between the two groups. A significantly increased risk of vitiligo (hazard ratio = 1.99, 95% confidence interval = 1.06-3.75) was observed in the anti-TNF group compared to the unexposed group (5.9/10,000 person-years vs. 2.5/10,000 person-years). In subgroup analyses, younger patients and those treated with etanercept showed higher risks of vitiligo. The risk of alopecia areata was not significantly different between the two groups. Our results provide insight on the role of cytokine imbalance in the pathogenesis of vitiligo. PMID- 29175285 TI - Development of HyBeacon(r) probes for specific mRNA detection using body fluids as a model system. AB - HyBeacons are linear oligonucleotides which incorporate fluorescent dyes covalently linked to internal nucleotides. They have previously been used with PCR and isothermal amplification to interrogate SNPs and STRs in fields as diverse as clinical diagnostics, food authentication, and forensic DNA profiling. This work explores their use for the identification of expressed gene sequences through mRNA profiling. The use of mRNA is becoming increasingly common in forensic casework to identify body fluids on evidence items, as it offers higher specificity and fewer false positives than current chemical presumptive testing methods. The work presented here details the development of a single-step one tube RT-PCR assay to detect the presence of body fluids of forensic interest (saliva, blood, seminal fluid, vaginal fluid and menstrual blood) using HyBeacon(r) probes and melt curve analysis. Each assay shows a high degree of specificity to the target body fluid mRNA suggesting there is no requirement to remove genomic DNA prior to analysis. Of the five assays developed, four were able to detect between 10 and 100 copies of target cDNA, the fifth 1000 copies of target. The results presented here demonstrate that such an approach can be optimised for non-expert users and further areas of work are discussed. PMID- 29175286 TI - MicroRNA-34a modulates the Notch signaling pathway in mice with congenital heart disease and its role in heart development. AB - The objective of the study was to elucidate the mechanism by which microRNA-34a (miR-34a) influences heart development and participates in the pathogenesis of congenital heart disease (CHD) by targeting NOTCH-1 through the Notch signaling pathway. Forty D7 pregnant mice were recruited for the purposes of the study and served as the CHD (n=20, successfully established as CHD model) and normal (n=20) groups. The positive expression of the NOTCH-1 protein was evaluated by means of immunohistochemistry. Embryonic endocardial cells (ECCs) were assigned into the normal, blank, negative control (NC), miR-34a mimics, miR-34a inhibitors, miR-34a inhibitors+siRNA-NOTCH-1, siRNA-NOTCH-1, miR-34a mimics+NOTCH-1 OE and miR-34a mimics+crispr/cas9 (mutant NOTCH-1) groups. The expressions of miR-34a, NOTCH-1, Jagged1, Hes1, Hey2 and Csx in cardiac tissues and ECCs were determined by both RT-qPCR and western blotting methods. MTT assay and flow cytometry were conducted for cell proliferation and apoptosis measurement. A dual luciferase reporter assay was applied to demonstrate that NOTCH-1 was the target gene of miR-34a. In comparison to the normal group, the expressions of miR-34a, Jagged1, Hes1 and Hey2 displayed up-regulated levels, while the expressions of NOTCH-1 and Csx were down-regulated in the CHD group. Compared with the blank and NC groups, the miR 34a mimics and siRNA-NOTCH-1 groups displayed reduced expressions of NOTCH-1 and Csx as well as a decreased proliferation rate, higher miR-34a, Jagged1, Hes1 and Hey2 expressions and an increased rate of apoptosis; while an reverse trend was observed in the miR-34a inhibitors group. The expressions of MiR-34a recorded increased levels in the miR-34a mimics+NOTCH-1 OE and miR-34a mimics+crispr/cas9 (mutant NOTCH-1) groups, however no changes in the expressions of NOTCH-1, Jagged1, Hes1, Hey2, Csx, as well as cell proliferation and apoptosis were observed when compared to the blank and NC groups. The results of our study demonstrated that miR-34a increases the risk of CHD through its downregulation of NOTCH-1 by modulating the Notch signaling pathway.

AB - Shells of brachiopods are excellent archives for environmental reconstructions in the recent and distant past as their microstructure and geochemistry respond to climate and environmental forcings. We studied the morphology and size of the basic structural unit, the secondary layer fibre, of the shells of several extant brachiopod taxa to derive a model correlating microstructural patterns to environmental conditions. Twenty-one adult specimens of six recent brachiopod species adapted to different environmental conditions, from Antarctica, to New Zealand, to the Mediterranean Sea, were chosen for microstructural analysis using SEM, TEM and EBSD. We conclude that: 1) there is no significant difference in the shape and size of the fibres between ventral and dorsal valves, 2) there is an ontogenetic trend in the shape and size of the fibres, as they become larger, wider, and flatter with increasing age. This indicates that the fibrous layer produced in the later stages of growth, which is recommended by the literature to be the best material for geochemical analyses, has a different morphostructure and probably a lower organic content than that produced earlier in life. In two species of the same genus living in seawater with different temperature and carbonate saturation state, a relationship emerged between the microstructure and environmental conditions. Fibres of the polar Liothyrella uva tend to be smaller, rounder and less convex than those of the temperate Liothyrella neozelanica, suggesting a relationship between microstructural size, shell organic matter content, ambient seawater temperature and calcite saturation state. PMID- 29175290 TI - Trends and key correlates of prescription opioid injection misuse in the United States. AB - BACKGROUND: Despite concerns over increasing harms associated with prescription opioid injection misuse, there is a paucity of research on the magnitude, characteristics, injection practices, and syringe sources for people who inject prescription opioids; limiting the implementation of targeted policy and programmatic initiatives. MATERIALS AND METHODS: Data from the 2003 through 2014 National Surveys on Drug Use and Health were used to estimate prescription opioid injection trends and examine risky injection practices and syringe sources for people who inject prescription opioids. Multivariable logistic regression was used to identify characteristics associated with prescription opioid injection. RESULTS: Among people 12years or older, the rate of prescription opioid injection misuse increased from 1.6 per 1000 in 2003-2005 to 2.7 per 1000 in 2012-2014 (p value for trend <0.05). Groups with increased odds of prescription opioid injection included: males, non-Hispanic whites, having an annual household income <$50,000, the uninsured, people with Medicaid, and people with past-year use disorders for cocaine, heroin, or prescription opioids. Risky injection practices such as reusing a needle and sharing needles were common among people with a history of prescription opioid injection misuse. CONCLUSION: This study found significant increases in prescription opioid injection misuse trends in the U.S. These findings underscore the need to bring to scale evidence-based interventions to increase the provision of medication-assisted treatment for opioid use disorders and expand access to comprehensive risk-reduction services for people who inject drugs. PMID- 29175291 TI - Testing competing models of injunctive and descriptive norms for proximal and distal reference groups on alcohol attitudes and behavior. AB - INTRODUCTION: Injunctive norms represent perceptions regarding the extent that others approve of a behavior, whereas descriptive norms represent perceptions of the extent that others engage in a behavior. This study evaluated competing path models, varying in the representation of injunctive and descriptive norm constructs, to forecast alcohol attitudes and use. METHODS: College students (N=326) answered questions about their normative perceptions regarding three relevant reference groups (typical students, friends, and parents) in the form of alcohol injunctive and descriptive norms. Personal alcohol attitudes (approval) and usage were assessed one month later. RESULTS: The path analysis model arranged by injunctive versus descriptive found that injunctive norms explained attitudes, but descriptive norms contributed to behavior. In the path analysis model of constructs organized by reference groups, friend and parent norms uniquely contributed to attitudes, but typical student, friend, and parental norms contributed to use. Finally, the comprehensive model based on each reference group combination with injunctive and descriptive norms (e.g., typical student injunctive) determined that friend injunctive norms and parent injunctive norms uniquely forecasted alcohol attitudes, whereas typical student injunctive norms, typical student descriptive norms, and friend descriptive norms forecasted behavior. CONCLUSIONS: A novel contribution of the study is the scrutiny of competing models of alcohol norms using the same multifaceted measures. Disparate implications emerge about the role of subjective norms as a function of the approach to compute the constructs. The most nuanced insights were obtained in the final comprehensive model involving the representation of norms at the finest level of specificity.

AB - College students with social anxiety disorder experience more alcohol-related negative consequences, regardless of the amount of alcohol they consume. Social anxiety refers to psychological distress and physiological arousal in social situations due to an excessive fear of negative evaluation by others. The current study examined within-group differences in alcohol-related negative consequences of students who met or exceeded clinically-indicated social anxiety symptoms. In particular, we tested a sequential mediation model of the cognitive (i.e., fear of negative evaluation) and behavioral (protective behavioral strategies) mechanisms for the link between social anxiety disorder subtypes (i.e., interaction and performance-type) and alcohol-related negative consequences. Participants were 412 traditional-age college student drinkers who met or exceeded the clinically-indicated threshold for social anxiety disorder and completed measures of fear of negative evaluation, protective behavioral strategies (controlled consumption and serious harm reduction), and alcohol related negative consequences. Fear of negative evaluation and serious harm reduction strategies sequentially accounted for the relationship between interaction social anxiety disorder and alcohol-related negative consequences, such that students with more severe interaction social anxiety symptoms reported more fear of negative evaluation, which was related to more serious harm reduction strategies, which predicted fewer alcohol-related negative consequences. Future directions and implications are discussed.

AB - One of the central pathways to problem gambling (PG) is gambling to cope with negative moods, which is a cardinal feature of depression. Insecure attachment styles are also etiologically related to depression; and, therefore, by extension, those who are insecurely attached may engage in excessive gambling behaviors to cope with depression. In this study, we aimed to evaluate this and to this end predicted that depression severity and coping motives for gambling would conjointly mediate the relations between insecure attachment styles and PG. Data came from a larger investigation of PG within mood disorders. Participants exhibited a lifetime depressive or bipolar disorder and endorsed a mood episode within the past ten years. Participants (N=275) completed self-report measures during a two-day assessment. Path analysis supported two main indirect effects. First, anxious attachment predicted elevated depression, which in turn predicted increased coping motives for gambling, which subsequently predicted greater PG severity. Second, this double mediational pathway was also observed for avoidant attachment. Results suggest that insecure attachment relates to PG via depressive symptoms and coping-related gambling motives. Mood symptoms and associated gambling motives are malleable and are promising targets of gambling interventions for insecurely attached individuals. PMID- 29175294 TI - Parachuting psychoactive substances: Pharmacokinetic clues for harm reduction. AB - BACKGROUND: Parachuting, also called bombing, is a way to ingest psychoactive substances wrapped into cigarette paper, toilet paper, etc. There is little data describing parachuting in terms of substances use, context of use and, most importantly, the motivations for using such wrappers, although some authors hypothesized that parachute could be used for pharmacokinetic reason. However, inconsistently, some authors report that parachutes are used for sustained release whereas others report that users are looking for an immediate effect. RESEARCH DESIGN AND METHODS: Considering parachute as a "home-made" dosage form, we have applied the dissolution testing to characterize the dissolution performance of a substance wrapped into a parachute and to characterize whether a parachute represents an immediate-release form or not. RESULTS: This in-vitro study provides the first pharmacokinetic data for drugs wrapped in parachutes. It shows that parachute acts as sustained-release form when made with a cigarette paper wrapper, but as immediate release form in the presence of alcohol or if wrapped with toilet paper. CONCLUSIONS: An important message to harm reduction is that users must be aware that a parachute can have unexpected pharmacokinetics and have to avoid taking another parachute in the absence of an immediate-effect to avoid overdose. PMID- 29175295 TI - Pain anxiety differentially mediates the association of pain intensity with function depending on level of intolerance of uncertainty. AB - Uncertainty about symptom duration, cause, prognosis and treatment is common in patients who seek medical care, yet individual ability to manage this uncertainty varies. Intolerance of uncertainty is considered an important factor in the etiology and persistence of negative emotions- in particular, depression and anxiety. We explored the contribution of intolerance of uncertainty to anxiety due to pain and physical function in patients seeking care at an orthopedic medical practice. Participants (N = 105, mean age of 51 +/- 17, 63% male) were administered PROMIS Physical Function v1.2 Upper Extremity CAT, Numerical Rating Scale (NRS), Pain Anxiety Symptoms Scale-short form (PASS-20), and the Intolerance of Uncertainty Scale-short version (IUS-12). Results showed that the mediating role of pain anxiety is contingent upon the level of intolerance of uncertainty. Specifically, a minimum level of intolerance of uncertainty is required for the development of pain anxiety and its effect on function, and as intolerance of uncertainty rises from low to medium to high levels, the effect of pain on function goes from being independent of the anxiety to being more and more carried by and through anxiety about pain. These findings support the contention that intolerance of uncertainty plays a crucial role in the relationship between pain, pain anxiety, and physical function. Intolerance of uncertainty appears to be a trans-diagnostic target for coping skills training. PMID- 29175296 TI - Eating styles in major depressive disorder: Results from a large-scale study. AB - Depressed persons have been found to present disturbances in eating styles, but it is unclear whether eating styles are different in subgroups of depressed patients. We studied the association between depressive disorder, severity, course and specific depressive symptom profiles and unhealthy eating styles. Cross-sectional and course data from 1060 remitted depressed patients, 309 currently depressed patients and 381 healthy controls from the Netherlands Study of Depression and Anxiety were used. Depressive disorders (DSM-IV based psychiatric interview) and self-reported depressive symptoms (Inventory of Depressive Symptomatology) were related to emotional, external and restrained eating (Dutch Eating Behavior Questionnaire) using analyses of covariance and linear regression. Remitted and current depressive disorders were significantly associated with higher emotional eating (Cohen's d = 0.40 and 0.60 respectively, p < 0.001) and higher external eating (Cohen's d = 0.20, p = 0.001 and Cohen's d = 0.32, p < 0.001 respectively). Little differences in eating styles between depression course groups were observed. Associations followed a dose-response association, with more emotional and external eating when depression was more severe (both p-values <0.001). Longer symptom duration was also associated to more emotional and external eating (p < 0.001 and p = 0.001 respectively). When examining individual depressive symptoms, neuro-vegetative depressive symptoms contributed relatively more to emotional and external eating, while mood and anxious symptoms contributed relatively less to emotional and external eating. No depression associations were found with restrained eating. Intervention programs for depression should examine whether treating disordered eating specifically in those with neuro-vegetative, atypical depressive symptoms may help prevent or minimize adverse health consequences. PMID- 29175297 TI - Impulsivity in unaffected adolescent biological relatives of schizophrenia patients. AB - OBJECTIVE: Although schizophrenia is not a prototypic impulse-control disorder, patients report more impulsive behaviors, have higher rates of substance use, and show dysfunction in brain circuits that underlie impulsivity. We investigate impulsivity in unaffected biological relatives of schizophrenia patients to further understand the relationships between schizophrenia risk and impulse control during adolescence. METHOD: Group differences in impulsivity (UPPS-P Impulsive Behavior Scale and delay discounting) were tested in 210 adolescents contrasting 39 first- and 53 second-degree biological relatives of schizophrenia patients, and 118 subjects with no schizophrenia family history (NSFH). RESULTS: Compared to NSFH adolescents and to second-degree relatives, first-degree relatives of schizophrenia patients had increased impulsivity-related behaviors (higher UPPS-P Perseverance, Positive Urgency and Premeditation subscale scores) and greater preference for immediate rewards (smaller AUC and larger discounting constant). Second-degree relatives did not differ significantly from NSFH adolescents on self-report impulsive behaviors or on measures of impulsive decision-making. These group differences remained even after careful consideration of potential confounding factors. CONCLUSION: Impulsivity is associated with schizophrenia risk, and its severity increases with greater familial relatedness to the schizophrenia proband. Additional studies are needed to understand the role impulsivity may play in mediating schizophrenia susceptibility during adolescence. PMID- 29175298 TI - Does type 2 diabetes affect the on-treatment levels of direct oral anticoagulants in patients with atrial fibrillation? AB - AIMS: Type 2 diabetes (T2D) is connected with several abnormalities in haemostasis; and with higher risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NV-AF). However, it is recently unknown whether T2D affects the activity of direct oral anticoagulants (DOACs). The aim of this study was to determine the impact of T2D on DOACs activity in patients with NV-AF. METHODS: This pilot prospective study enrolled totally 65 patients with NV-AF (20 dabigatran-treated, 110 mg/twice daily; 28 rivaroxaban-treated, 15 mg/daily; 17 apixaban-treated, 5 mg/twice daily). 25 patients had T2D (8 dabigatran-treated, 11 rivaroxaban-treated, and 6 apixaban-treated). DOAC activity was tested with Hemoclot(r) Thrombin Inhibitor assay in dabigatran treated patients, and with factor Xa-calibrated anti-Xa chromogenic analysis in rivaroxaban- and apixaban-treated patients prior and two hours after drug administration. RESULTS: There were no significant differences in dabigatran baseline (62.1 +/- 8.0 vs. 51.8 +/- 38.9 ng/ml, p = .76) and 2-h-post-drug administration (91.7 +/- 57.2 vs. 72.2 +/- 33.2 ng/ml, p = .48) activity comparing T2D and non-diabetic patients. Similarly, no significant differences were found in rivaroxaban baseline (35.9 +/- 22.5 vs. 55.3 +/- 45.1 ng/ml, p = .19) and 2-h-post-drug-administration (145.7 +/- 74.1 vs. 202.6 +/- 135.0 ng/ml, p = .22) anti-Xa activity. In addition, no significant differences were present in apixaban baseline (96.0 +/- 54.5 vs. 63.9 +/- 36.8 ng/ml, p = .24) and 2-h post-drug-administration (151.0 +/- 78.3 vs. 151.7 +/- 59.1 ng/ml, p = .98) anti Xa activity between T2D and non-diabetic patients. CONCLUSIONS: This pilot study did not detect differences in DOACs activity according to T2D status in patients with NV-AF. PMID- 29175299 TI - Verbal labels facilitate tactile perception. AB - One of the key statements of linguistic relativity is that language has a causal effect on perception. Although much previous research has addressed such putative language perception causality, no firm proof is available thus far which demonstrates that verbal labels help or otherwise influence perceptual processes. Here, we tested the hypothesis of language perception causality by using novel, minimally-different tactile-patterned stimuli applied to the finger, which initially could not be discriminated by our participants. By combining novel verbal pseudoword- and novel tactile-patterned stimuli in an implicit learning experiment, we show a language-induced facilitation in tactile-patterned stimulus discrimination. After one week of intensive yet implicit learning of tactile stimuli in the presence of irrelevant consistent verbal labels, participants demonstrated significant discrimination improvement. In contrast, the same participants showed no improvement in discriminating tactile-patterned stimuli that had been learnt in the context of variable linguistic stimuli. These results show that specific mental links between verbal labels and perceptual information brought about by their correlated presentation enable one to better discriminate said sensory information (and build percepts). PMID- 29175300 TI - Perfluorooctanoic acid and low birth weight: Estimates of US attributable burden and economic costs from 2003 through 2014. AB - BACKGROUND AND OBJECTIVE: In utero exposure to perfluorooctanoic acid (PFOA) has been associated with decreases in birth weight. We aimed to estimate the proportion of PFOA-attributable low birth weight (LBW) births and associated costs in the US from 2003 to 2014, a period during which there were industry initiated and regulatory activities aimed at reducing exposure. METHODS: Serum PFOA levels among women 18-49 years were obtained from the National Health and Nutrition Examination Survey (NHANES) for 2003-2014; birth weight distributions were obtained from the Vital Statistics Natality Birth Data. The exposure response relationship identified in a previous meta-analysis (18.9g decrease in birth weight per 1ng/mL of PFOA) was applied to quantify PFOA-attributable LBW (reference level of 3.1ng/mL for our base case, 1 and 3.9ng/mL for sensitivity analyses). Hospitalization costs and lost economic productivity were also estimated. RESULTS: Serum PFOA levels remained approximately constant from 2003 2004 (median: 3.3ng/mL) to 2007-2008 (3.5ng/mL), and declined from 2009-2010 (2.8ng/mL) to 2013-2014 (1.6ng/mL). In 2003-2004, an estimated 12,764 LBW cases (4% of total for those years) were potentially preventable if PFOA exposure were reduced to the base case reference level (10,203 cases in 2009-2010 and 1,491 in 2013-2014). The total cost of PFOA-attributable LBW for 2003 through 2014 was estimated at $13.7 billion, with $2.97 billion in 2003-2004, $2.4 billion in 2009 2010 and $347 million in 2013-2014. CONCLUSIONS: Serum PFOA levels began to decline in women of childbearing age in 2009-2010. Declines were of a magnitude expected to meaningfully reduce the estimated incidence of PFOA-attributable LBW and associated costs. PMID- 29175301 TI - A straightforward assay to evaluate DNA integrity and optimize next-generation sequencing for clinical diagnosis in oncology. AB - Next generation sequencing (NGS) has become an informative tool to guide cancer treatment and conduce a personalized approach in oncology. The biopsy collected for pathologic analysis is usually stored as formalin-fixed paraffin-embedded (FFPE) blocks and then availed for molecular diagnostic, resulting in DNA molecules that are invariably fragmented and chemically modified. In an attempt to improve NGS based diagnostics in oncology we developed a straightforward DNA integrity assessment assay based on qPCR, defining clear parameters to whether NGS sequencing results is accurate or when it should be analyzed with caution. We performed DNA extraction from 12 tumor samples from diverse tissues and accessed DNA integrity by straightforward qPCR assays. In order to perform a cancer panel NGS sequencing, DNA library preparation was performed using RNA capture baits. Reads were aligned to the reference human genome and mutation calls were further validated by Sanger sequencing. Results obtained by the DNA integrity assays correlated to the efficiency of the pre-capture library preparation in up to 0.94 (Pearson's test). Moreover, sequencing results showed that poor integrity DNA leads to high rates of false positive mutation calls, specially C:G>T:A and C:G>A:T. Poor quality FFPE DNA samples are prone to generating false positive mutation calls. These are especially perilous in cases in which subclonal populations are expected, such as in advance disease, since it could lead clinicians to erroneous conclusions and equivocated conduct. PMID- 29175302 TI - Matrix metalloproteinase and heparin-stimulated serine proteinase activities in post-prostate massage urine of men with prostate cancer. AB - Proteinases secreted by the prostate gland have a reproductive function in cleaving proteins in the ejaculate and in the female reproductive tract, but some may have a fundamental role in disease and pathological processes including cancer. The purpose of this study was to determine if there were differences in proteinase activities in urine samples collected following prostate massage of men positive (CaP) or negative (no evidence of malignancy, NEM) for biopsy determined prostate cancer. Matrix metalloproteinase (MMP) and serine proteinase activities were detected using protein substrate zymography. There were no differences in activities of MMP-2, proMMP-9, and MMP-9/NGAL (neutrophil gelatinase associated lipocalin) complex (gelatin substrate) in men with detected prostate cancer, although the latter two were somewhat diminished. A caseinolytic activity of about 75kDa inhibited by calcium did not differ between the NEM and CaP groups. Heparin stimulated calcium sensitive gelatinolytic activities of approximately 22, 42, and 60kDa, but did not affect activities of MMP-2, MMP-9, or the 75kDa caseinolytic activity. The 22, 42, and 60kDa activities appear to be serine proteinases since they were inhibited by benzamidine. There was a significant decrease in the 22kDa heparin-stimulated serine proteinase activity in urines of men with cancer. Proteinase expression and activities, perhaps in combination with other potential markers, may prove useful in urine for detection and evaluation of prostate cancer. PMID- 29175304 TI - Age, sex, and TNF associated differences in the gut microbiota of mice and their impact on acute TNBS colitis. AB - Mouse models are often used to determine the interactions between the microbiota and inflammatory processes and overcome the confounding effect of the naturally high inter-individual variation of the gut microbiota in humans. However, the microbiomes of mice are also variable and data detailing the degree to which factors like mouse sex and age contribute to mouse gut microbiota variation is limited. Our objective was to determine the impact sex and age have on the mouse gut microbiota and the severity of acute 2, 4, 6-trinitrobenzenesulfonic acid (TNBS) induced colitis. We used Illumina sequencing of 16S rRNA genes to characterize the fecal microbiota of B6.129S wild-type (WT) mice and mice lacking tumor necrosis factor (Tnf-/-) before and after acute TNBS colitis. There were differences between the fecal microbiota of male and female WT mice as well as Tnf-/- mice, both pre-and post-colitis. Male WT mice had more severe colitis than female WT mice and Tnf-/- mice of both sexes. We also identified microbial taxa differences between 4-5 and 6-7-week old WT and Tnf-/- mice both pre-and post colitis. Here we provide evidence that the mouse fecal microbiome is shaped, in part, by sex, age and TNF production and that these effects correlate with the degree of animals' colitis. PMID- 29175305 TI - Balancing precision with inclusivity in meta-analyses: A response to Roos and colleagues (2017). AB - Roos and colleagues' commentary on our recent meta-analysis examining acute stress effects on executive functions is an important delineation of the limits of meta-analyses with heterogeneous outcomes. In this response, we wish to both clarify the inferences we feel are appropriate given the analyses and address the methodological concerns they raise. Additionally, we present new analyses that answer questions raised in their commentary. We first discuss the classification of a broad array of tasks that depend upon the same construct (e.g., inhibition) and note that this allows for inferences regarding the process that underpins all of those tasks, but this does not entail that all tasks dependent upon that construct will evidence the same effect of stress. Second, we argue that requiring that a study present a significant effect of stress on cortisol for inclusion in analyses is too stringent for a number of reasons (e.g., some studies using validated stressor paradigms correctly do not assay cortisol for budgetary reasons) and we present analyses showing that even when studies that did not present a cortisol response were removed, the initially observed effects still held. Finally, we address concerns raised regarding analyses of time dependent effects by presenting new analyses that help to allay those concerns. In sum, we applaud Roos and colleagues' exortation for greater methodological and conceptual rigor in studies of stress and executive function, and the additional analyses prompted by their questions help to clarify observed effects and further the field of stress and executive function research. PMID- 29175303 TI - EGFR, KRAS, BRAF and HER2 testing in metastatic lung adenocarcinoma: Value of testing on samples with poor specimen adequacy and analysis of discrepancies. AB - Molecular testing on metastatic lung adenocarcinoma or on non-small cell non squamous lung carcinoma often relies on small specimen. In this group of patient with poor specimen adequacy, we analyzed the rate of EGFR, KRAS, BRAF and HER2 mutations compared to their rate in optimal specimen. We analyzed discrepancies in molecular testing results in patients with iterative analysis on several samples. We performed a retrospective study of 1538 samples consecutively analyzed. 263/665 (39,5%) biopsies and 37/708 (5,2%) surgical specimens were considered as samples with poor specimen adequacy (p<0,0001). A lower tumor cell content was associated with a lower rate of KRAS mutation: 15,8% in samples with <10% of tumor cells or <100 tumor cells versus 29,8% in samples with >10% tumor cell and >100 tumor cells (p=0,001). KRAS mutational rate was at 11,1% in cytology specimens, significantly lower than in biopsy or surgical specimens respectively at 28,2% and 28,5% (p=0,0002). Tumor cell content was not associated with mutational rate for EGFR, BRAF and HER2 mutations. DNA quantity was not associated with mutational rate for EGFR, KRAS, BRAF and HER2. A discrepancy in molecular testing was found in 16 patients. For 5 patients there was also a discrepancy for TTF-1 expression. On the 11 without TTF-1 discrepancy, specimen adequacy was not fulfilled in 10 cases at least for tumor content. Discrepancies were found in the case of low cellularity, poor cell content or testing on cytological specimens. Tumor cell content is a crucial parameter for molecular analysis rather than the type of specimen or the DNA quantity. Discrepancies in molecular testing results are rare but might suggest the presence of another tumor type, the emergence of another clone or a molecular testing in a sample with low cell content. PMID- 29175306 TI - Embodiment in the aging mind. AB - Bodily awareness is a central component of human sensation, action, and cognition. The human body is subject to profound changes over the adult lifespan. We live in an aging society: the mean age of people living in industrialized countries is currently over 40 years, and further increases are expected. Nevertheless, there is a lack of comprehensive knowledge that links changes in embodiment that occur with age to neuronal mechanisms and associated sensorimotor and cognitive deficits in older adults. Here, we synthesize existing evidence and introduce the NFL Framework of Embodied Aging, which links basic neuronal (N) mechanisms of age-related sensorimotor decline to changes in functional (F) bodily impairments, including deficits in higher-level cognitive functions, and impairments in daily life (L). We argue that cognitive and daily life impairments associated with old age are often due to deficits in embodiment, which can partly be linked to neuronal degradation at the sensorimotor level. The framework may encourage the development of novel approaches to improve autonomous living for older adults. PMID- 29175307 TI - Extracellular vesicles in obesity and diabetes mellitus. AB - Cell-to-cell communication happens via diverse mechanisms including the synthesis, release and transfer to target cells of extracellular vesicles (EVs). EVs include nanovesicles (i.e., exosomes) and microvesicles, including apoptotic bodies. The amount and cargo of released EVs, which consist of microRNAs (miRNAs), mRNA, proteins, DNA, among other molecules, are altered in obesity and diabetes mellitus. EVs from these diseases show with altered cargo including several miRNAs and the enrichment with molecules involved in inflammation, immune efficiency, and cell activation. The role of EVs in obesity regards with adipocytes-released vesicles that may end in a systemic insulin resistance. In diabetes mellitus, the exosomes cargo may signal to transform a normal phenotype into a diabetic phenotype in endothelial cells. The evidence of EVs as modulators of cell function is increasing; however, it is still unclear whether exosomes or microvesicles are a trustable and useful marker for the diagnose or early detection of obesity or diabetes mellitus. In this review, we summarise the reported information regarding EVs involvement in obesity, T1 and T2 diabetes mellitus, and gestational diabetes mellitus. We emphasise the fact that studies addressing a potential effect of obesity or diabetes mellitus on cell function and the severity of the diseases are done in patients suffering simultaneously with both of these diseases, i.e., diabesity. Unfortunately, the lack of information regarding the biological effects and the potential involved mechanisms makes difficult to understand the role of the EVs as a marker of these and perhaps other diseases. PMID- 29175308 TI - Differential use of danger and safety signals in an animal model of anxiety vulnerability: The behavioral economics of avoidance. AB - Differential processing of danger and safety signals may underlie symptoms of anxiety disorders and posttraumatic stress disorder. One symptom common to these disorders is pathological avoidance. The present study examined whether danger and safety signals influence avoidance differently in anxiety-vulnerable Wistar Kyoto (WKY) rats and Sprague Dawley (SD) rats. SD and WKY rats were tested in a novel progressive ratio avoidance task with and without danger or safety signals. Two components of reinforcement, hedonic value and motivation, were determined by fitting an exponentiated demand equation to the data. Hedonic value of avoidance did not differ between SD and WKY rats, but WKY rats had greater motivation to avoid than SD rats. Removal of the safety signal reduced motivation to avoid in SD, but not WKY, rats. Removal of the danger signal did not alter avoidance in either strain. When danger and safety signals were presented simultaneously, WKY rats responded to the danger signals, whereas SD rats responded to the safety signal. The results provide evidence that 1) safety signals enhance motivation to avoid in SD rats, 2) both danger and safety signals influence motivation in WKY rats, and 3) danger signals take precedence over safety signals when presented simultaneously in WKY rats. Thus, anxiety vulnerability is associated with preferential use of danger signals to motivate avoidance. The differential use of danger and safety signals has important implications for the etiology and treatment of pathological avoidance in anxiety disorders and posttraumatic stress disorder. PMID- 29175310 TI - No More 'Code Black': Intervention to Improve Inpatient Flow at a Large Public Hospital. PMID- 29175311 TI - Three of a (Peptic) Kind! PMID- 29175309 TI - Altered neuro-inflammatory gene expression in hippocampus in major depressive disorder. AB - Major Depressive Disorder (MDD) is a common psychiatric disorder for which available medications are often not effective. The high prevalence of MDD and modest response to existing therapies compels efforts to better understand and treat the disorder. Decreased hippocampal volume with increasing duration of depression suggests altered gene expression or even a decrease in neurogenesis. Tissue punches from the dentate gyrus were collected postmortem from 23 subjects with MDD and 23 psychiatrically-normal control subjects. Total RNA was isolated and whole transcriptome paired-end RNA-sequencing was performed using an Illumina NextSeq 500. For each sample, raw RNA-seq reads were aligned to the Ensembl GRCh38 human reference genome. Analysis revealed 30 genes differentially expressed in MDD compared to controls (FDR<0.05). Down-regulated genes included several with inflammatory function (ISG15, IFI44L, IFI6, NR4A1/Nur-77) and GABBR1 while up-regulated genes included several with cytokine function (CCL2/MCP-1), inhibitors of angiogenesis (ADM, ADAMTS9), and the KANSL1 gene, a histone acetyltransferase. Similar analyses of specific subsets of MDD subjects (suicide vs. non-suicide, single vs. multiple episodes) yielded similar, though not identical, results. Enrichment analysis identified an over-representation of inflammatory and neurogenesis-related (ERK/MAPK) signaling pathways significantly altered in the hippocampal dentate gyrus in MDD. Together, these data implicate neuro-inflammation as playing a crucial role in MDD. These findings support continued efforts to identify adjunctive approaches towards the treatment of MDD with drugs including anti-inflammatory and neuroprotective properties. PMID- 29175312 TI - Splenic Rupture After Same Level Fall. PMID- 29175313 TI - Relevance of the chaperone-like protein calreticulin for the biological behavior and clinical outcome of cancer. AB - The death of cancer cells can be categorized as either immunogenic (ICD) or nonimmunogenic, depending on the initiating stimulus. The immunogenic processes of immunogenic cell death are mainly mediated by damage-associated molecular patterns (DAMPs), which include surface exposure of calreticulin (CRT), secretion of adenosine triphosphate (ATP), release of non-histone chromatin protein high mobility group box 1 (HMGB1) and the production of type I interferons (IFNs). DAMPs are recognized by various receptors that are expressed by antigen presenting cells (APCs) and potentiate the presentation of tumor antigens to T lymphocytes. Accumulating evidence indicates that CRT exposure constitutes one of the major checkpoints, that determines the immunogenicity of cell death both in vitro and in vivo in mouse models. Moreover, recent studies have identified CRT expression on tumor cells not only as a marker of ICD and active anti-tumor immune reactions but also as a major predictor of a better prognosis in various cancers. Here, we discuss the recent information on the CRT capacity to activate anticancer immune response as well as its prognostic and predictive role for the clinical outcome in cancer patients. PMID- 29175314 TI - Immunomodulatory properties of umbilical cord vein mesenchymal stromal cells influenced by gestational age and in vitro expansion. AB - In vivo and in vitro aging of the mesenchymal stromal cells (MSCs) can affects their properties. We investigated the immunomodulatory properties of the term and preterm human umbilical cord vein MSCs (UCV-MSCs) at the passages (P) 2 and 5. Term and preterm UCV-MSCs at P2 and 5 were co-cultured with two-way mixed lymphocyte reaction. Proliferation, IFN-gamma and IL-10 protein levels, mRNA levels of the COX-2, TGF-beta1, TNF-alpha, IL-4 and FoxP3 were assessed. The term UCV-MSCs and P5 of the term and preterm UCV-MSCs had stronger inhibitory effects on cell proliferation than the preterm UCV-MSC and P2, respectively (P = 0.001). In supernatants of the co-cultures, IFN-gamma was higher in the term UCV-MSC than the preterm UCV-MSC, while IL-10 was higher in the preterm UCV-MSCs than the term UCV-MSCs. Also in the co-cultures, COX-2 expression in the term UCV-MSCs and P2 was higher than the preterm UCV-MSCs and P5, respectively and TGF-beta1 expression in the term UCV-MSCs was higher than preterm. Conclusively it appears that the term UCV-MSCs, and P5 of the term and preterm UCV-MSCs showed a higher immunomodulatory ability than the preterm UCV-MSCs and P2, respectively. PMID- 29175315 TI - Flagellin increases death receptor-mediated cell death in a RIP1-dependent manner. AB - Efficient adjuvants have the potential to trigger both innate and adaptive immune responses simultaneously. Flagellin is a unique pathogen-derived protein, which is recognized by pattern recognition receptors (PRRs) as well as by B-cell and T cell receptors thus providing an important link between innate and adaptive immunity. The aforementioned properties define flagellin as an optimal adjuvant. The induction of immunogenic cell death could be an additional expectation for adjuvants in the context of cancer immunotherapy due to their ability to activate dendritic cells (DC) to present tumor antigens through the engulfment of dying cells. The immunostimulatory potential of flagellin in the course of DC and lymphocyte activation is well documented, however the exact mechanism is not fully explored. Based on this limitation we sought to investigate the potential modulatory effects of flagellin on various cell death processes knowing that it plays detrimental roles in regulating the final outcome of various types of immune responses. Here we provide evidence that the pre-treatment of Jurkat T cells with recombinant flagellin is able to increase the degree of cell death provoked by FasL or TNF-alpha, and concomitantly increases the cytotoxic potential of phytohemagglutinin activated T-lymphocytes in a TLR5 dependent way. In contrast to these flagellin-mediated effects on the death receptor-induced signaling events, the mitochondrial apoptotic pathway remained unaffected. Furthermore, the cell culture supernatant of wild type Salmonella enteritidis bacteria, but not their flagellin deficient variant, was able to enhance the Fas induced cell death process. To define the molecular mechanisms of flagellin mediated elevated levels of cell death we were able to detect the upregulation of RIP1-dependent signaling events. These findings demonstrate that the cooperative actions of pattern recognition and different death receptors are able to initiate the cell death process with the mobilization of RIP-dependent cell death modalities. This finding highlights the capability of flagellin to act as a potential adjuvant which is relevant for tumor immunotherapy. PMID- 29175317 TI - Epitope identification of specific naturally occurring human anti-avidin antibodies. AB - Human serum contains natural antibodies against avidin. Affinity purified natural anti-avidin human IgG exhibits affinity constants comparable to those of antibodies produced by active immunization of rabbits. Using a random hexapeptide library displayed on the filamentous M13 phage, and rabbit anti-avidin purified antibodies as a selector, we searched for epitopes shared by both selector and natural human anti-avidin IgG. This approach, enabled the isolation and identification of phagotopes bearing consensus motifs similar to sequence stretches of the avidin loops and beta-sheet regions. These phagotopes were recognized by the natural human anti-avidin antibodies. The fact that natural anti-avidin antibodies in human serum have similar epitopes to those of IgG elicited by active immunization of animals, led us to suggest that small peptide epitopes may prevent deleterious effects caused by antibodies formed against food proteins as well as therapeutic proteins.

AB - INTRODUCTION: Immunotherapy with tumor-associated antigens (TAAs) is a potentially powerful approach to eradicate tumor cells. The receptor tyrosine kinase-like orphan receptor 1 (ROR1) plays a crucial role for survival of tumor cells and is overexpressed in various malignancies. In the present study, we developed a syngeneic mouse tumor model to assess anti-tumor effect of mouse ROR1 specific polyclonal antibody (pAb) in vivo. MATERIALS AND METHODS: Mouse ROR1 specific antibody was produced in rabbit using recombinant ROR1 protein. Tow mouse tumor cell lines, (4T1 and CT26), were transfected with full length mouse ROR1 construct and stable clones were selected and characterized by immunocytochemistry, Western blot and flow cytometry. In vitro and in vivo anti tumor activities of anti-ROR1 antibody were assessed by XTT and syngeneic BALB/c mouse model, respectively. RESULTS: We successfully established two mouse ROR1 overexpressing tumor cell lines. The in vitro results indicate that the ROR1pAb did not significantly inhibit growth of ROR1+ cell lines. One of these cell lines (CT26-ROR1) was implanted in syngeneic BALB/c mice to assess anti-ROR1 tumor inhibitory activity in vivo. The tumor size was significantly reduced in mice treated with ROR1 specific pAb. CONCLUSION: Our results demonstrated for the first time tumor inhibitory effect of mouse ROR1 specific antibody in a syngeneic mouse tumor model. This model is a promising tool for preclinical assessment of ROR1 therapeutics and investigation of the underling molecular mechanisms.

AB - BACKGROUND: Blended learning, which combines internet-based platform and lecturing, is used in anaesthesiology and critical care teaching. However, the benefits of this method remain unclear. METHODS: We conducted a prospective, multicentre, non-randomised work between 2007 and 2014 to study the effect of blended learning on the results of first year anaesthesia and critical care residents in comparison with traditional teaching. Blended learning was implemented in Rouen University Hospital in 2011 and residents affiliated to this university corresponded as the blended learning group. The primary outcome was the resident's results as measured with multiple-choice questions between blended learning and control groups after beginning blended learning (post-interventional stage). The secondary outcomes included residents' results between pre and post interventional stages and homework's time. Moreover, comparison between control and blended learning group before beginning blended learning (pre-interventional stage) was performed. RESULTS: From 2007 to 2014, 308 residents were included. For the pre-interventional period, the mean score in the blended learning group (n=53) was 176 (CI 95% 163 to 188) whereas the mean score in the control group (n=106) was 167 (CI 95% 160 to 174) (no difference). For the post-interventional period, the mean score in blended learning group (n=54) was 232 on 300 (CI95% 227 237) whereas the mean score in the control group (n=95) is 215 (CI95% 209-220) (P<0.001). In the two groups, comparison between pre and post-interventional stages showed the increase of mean score, stronger for blended learning group (32% and 28% in blended learning and control group, P<0.05). The average time of homework in the blended learning group was 27h (CI 95% 18.2-35.8) and 10h in the control group (CI 95% 2-18) (P<0.05). CONCLUSIONS: This work suggests the positive effect of blended learning (associating internet-based learning and flipped classroom) on the anaesthesia and critical care residents' knowledge by increasing their homework's time.

AB - Mitochondria are classically known as the essential energy producers in cells. As such, the activation of mitochondrial metabolism upon cellular differentiation was deemed a necessity to fuel the high metabolic needs of differentiated cells. However, recent studies have revealed a direct role for mitochondrial activity in the regulation of stem cell fate and differentiation. Several components of mitochondrial metabolism and respiration have now been shown to regulate different aspects of stem cell differentiation through signaling, transcriptional, proteomic and epigenetic modulations. In light of these findings mitochondrial metabolism is no longer considered a consequence of cellular differentiation, but rather a key regulatory mechanism of this process. This review will focus on recent progress that defines mitochondria as the epicenters for the regulation of stem cell fate decisions. PMID- 29175321 TI - Methods for lineage tracing on the organism-wide level. AB - Determining the lineage origin of cell types is a major goal in developmental biology. Furthermore, lineage tracing is a powerful approach for understanding the origin of developmental defects as well as the origin of diseases such as cancer. There is now a variety of complementary approaches for identifying lineage relationships, ranging from direct observation of cell divisions by light microscopy to genetic labeling of cells using inducible recombinases and fluorescent reporters. A recent development, and the main topic of this review article, is the use of high-throughput sequencing data for lineage analysis. This emerging approach holds the promise of increased multiplexing capacity, allowing lineage analysis of large cell numbers up to the organism-wide level combined with simultaneous transcription profiling by single cell RNA sequencing. PMID- 29175322 TI - Illuminating information transfer in signaling dynamics by optogenetics. AB - Cells receive diverse signaling cues from their environment that trigger cascades of biochemical reactions in a dynamic manner. Single-cell imaging technologies have revealed that not only molecular species but also dynamic patterns of signaling inputs determine the fates of signal-receiving cells; however it has been challenging to elucidate how such dynamic information is delivered and decoded in complex networks of inter-cellular and inter-molecular interactions. The recent development of optogenetic technology with photo-sensitive proteins has changed this situation; the combination of microscopy and optogenetics provides fruitful insights into the mechanism of dynamic information processing at the single-cell level. Here, we review recent efforts to visualize the flows of dynamic patterns in signaling pathways, which utilize methods integrating single-cell imaging and optogenetics. PMID- 29175323 TI - Isolation and characterization of ventricular-like cells derived from NKX2 5eGFP/w and MLC2vmCherry/w double knock-in human pluripotent stem cells. AB - Human pluripotent stem cell (hPSC)-derived cardiomyocytes (CMs) are a promising source for cell transplantation into the damaged heart, which has limited regenerative ability. Many methods have been developed to obtain large amounts of functional CMs from hPSCs for therapeutic applications. However, during the differentiation process, a mixed population of various cardiac cells, including ventricular, atrial, and pacemaker cells, is generated, which hampers the proper functional analysis and evaluation of cell properties. Here, we established NKX2 5eGFP/w and MLC2vmCherry/w hPSC double knock-ins that allow for labeling, tracing, purification, and analysis of the development of ventricular cells from early to late stages. As with the endogenous transcriptional activities of these genes, MLC2v-mCherry expression following NKX2-5-eGFP expression was observed under previously established culture conditions, which mimic the in vivo cardiac developmental process. Patch-clamp and microelectrode array electrophysiological analyses showed that the NKX2-5 and MLC2v double-positive cells possess ventricular-like properties. The results demonstrate that the NKX2-5eGFP/w and MLC2vmCherry/w hPSCs provide a powerful model system to capture region-specific cardiac differentiation from early to late stages. Our study would facilitate subtype-specific cardiac development and functional analysis using the hPSC derived sources. PMID- 29175324 TI - Lixisenatide reduces amyloid plaques, neurofibrillary tangles and neuroinflammation in an APP/PS1/tau mouse model of Alzheimer's disease. AB - Type 2 diabetes mellitus (T2DM) has been identified as a high risk factor for Alzheimer's disease (AD). The impairment of insulin signaling has been found in AD brain. Glucagon-like peptide-1 (GLP-1) is an incretin hormone, normalises insulin signaling and acts as a neuroprotective growth factor. We have previously shown that the long-lasting GLP-1 receptor (GLP-1R) agonist lixisenatide plays an important role in memory formation, synaptic plasticity and cell proliferation of rats. In the follow-up study, we analysed the neuroprotective effect and mechanism of lixisenatide, injected for 60 days at 10 nmol/kg i.p. once daily in APP/PS1/tau female mice and C57BL/6J female mice (as control) aged 12 month. The results showed that lixisenatide could reduce amyloid plaques, neurofibrillary tangles and neuroinflammation in the hippocampi of 12-month-old APP/PS1/tau female mice; activation of PKA-CREB signaling pathway and inhibition of p38-MAPK might be the important mechanisms in the neuroprotective function of lixisenatide. The study demonstrated that GLP-1R agonists such as lixisenatide might have the potential to be developed as a novel therapy for AD. PMID- 29175325 TI - Fatty acid oxidation alleviates the energy deficiency caused by the loss of MPC1 in MPC1+/- mice. AB - Pyruvate is a central substrate in energy metabolism, paramount to carbohydrate, fat, and amino acid catabolic and anabolic pathways. Mitochondrial pyruvate carrier 1(MPC1) is one important component of the complex that facilitates mitochondrial pyruvate import. Complete MPC1 deficiency is a serious concern, and has been shown to result in embryonic lethality in mice. The study outlined in this paper generated one mouse line with the MPC1 protein part deficiency by using the CRISPR/Cas9 system. Clinical observations, body weight and organ/tissue weight, gas exchange, cold-stimulation, blood parameters, as well as histopathology analysis were analyzed to evaluate potential physiological abnormalities caused by MPC1 deficiency. Results indicate that MPC1+/- mice experienced a change in important clinical criteria such as low body weight, decreased movement, and low body shell temperature, few adipose accumulate. The mice show significant difference in some blood parameters including apo-B100, apo A1, HDL, glucagon, insulin. However these changes alleviated while being fed with the HFD, which provided metabolites to sustain the TCA cycle and body development. The MPC1+/- mice may employ fatty acid oxidation to meet their bioenergetic demands. This study suggests that inhibition of MPC1 activity can boost fatty acid oxidation to provide sufficient energy to the body. This work promotes further studies regarding the interplay between carbohydrate and fat metabolism. PMID- 29175326 TI - Downregulation of Nedd4L predicts poor prognosis, promotes tumor growth and inhibits MAPK/ERK signal pathway in hepatocellular carcinoma. AB - Accumulating evidence indicates that the neural precursor cell-expressed, developmentally downregulated 4-like (Nedd4L) related with some tumor progression pathways and was found abnormally expressed in several kinds of solid cancers. However, the role and mechanism of Nedd4L in HCC remain unknown. This study was to assess the role of Nedd4L in HCC tumorigenesis and prognosis. The real-time quantitative RT-PCR and immunohistochemistry results revealed that Nedd4L was downregulated in HCC tissues compared to corresponding peri-noncancerous tissue, and HCC patients with low expression of Nedd4L exhibited poor prognosis assessed by Kaplan-Meier and Cox regression analysis in 78 HCC patients. Furthermore, knockdown of Nedd4L could significantly promote proliferation of HCC cells by CCK 8 and colony formation assays in vitro; whereas ectopic expression of Nedd4L resulted in attenuating proliferation in vitro and tumor growth in vivc determined by nude mice xenografts model. Mechanically, Nedd4L could phosphorylate ERK1/2 and regulate genes related with apoptosis. Collectively, Nedd4L plays a tumor suppressive role in HCC, possibly through triggering MAPK/ERK-mediated apoptosis, and Nedd4L downregulation may be a potential prognostic biomarker as well as a therapeutic target for HCC. PMID- 29175327 TI - Structural basis for the interaction between DJ-1 and Bcl-XL. AB - DJ-1 is a multifunctional protein associated with Parkinson's disease (PD) and tumorigenesis. In response to ultraviolet B (UVB) irradiation, DJ-1 is translocated into the mitochondria, and its interaction with the mitochondrial protein Bcl-XL protects cells against death. In this study, we characterized the molecular interaction between DJ-1 and Bcl-XL by NMR spectroscopy. The NMR chemical shift perturbation data demonstrated that the oxidized but not the reduced form of DJ-1 binds to the predominantly hydrophobic groove surrounded by the BH1-BH3 domains in Bcl-XL. In addition, our results showed that the C terminal alpha8-helix peptide (Cpep) of DJ-1 binds to the pro-apoptotic BH3 peptide-binding hydrophobic groove in Bcl-XL and, thus, acts as a Bcl-XL-binding motif. In combination with the NMR chemical shift perturbation data, a refined structural model of the Bcl-XL/DJ-1 Cpep complex revealed that the binding mode is remarkably similar to that of other Bcl-XL/pro-apoptotic BH3 peptide complexes. Taken together, our results provide a structural basis for the binding mechanism between DJ-1 and Bcl-XL, which will contribute to molecular understanding of the role of mitochondrial DJ-1 in Bcl-XL regulation in response to oxidative stress. PMID- 29175328 TI - Construction of a high-yield dengue virus by replacing nonstructural proteins 3 4B without increasing virulence. AB - Producing virus at high yield is critically important for development of whole virion inactivated vaccines or live attenuated vaccines. Most dengue virus (DENV) clinical isolates, however, replicate at low levels in cultured cells, which limits their use for vaccine development. The present study examined differences between low-replicating DENV clinical isolates and high-replicating laboratory strains with the aim of engineering high-yield DENV clinical isolates. Construction of a series of recombinant chimeric viruses derived from a high replicating laboratory DENV type 4 (DENV-4) H241 strain and a clinical isolate revealed that the NS3-NS4B region of H241 conferred a replication advantage in cultured cells. Furthermore, northern blot analysis revealed that this advantage was due to more efficient synthesis of viral RNA. Importantly, replacement of the NS3-NS4B region of H241 did not increase virulence in mice, suggesting that viral production can be increased safely. This study provided information that will facilitate engineering of safe and high-yield viruses that can be used for vaccine development. PMID- 29175329 TI - Inhibition of CIP2A attenuates tumor progression by inducing cell cycle arrest and promoting cellular senescence in hepatocellular carcinoma. AB - CIP2A is a recent identified oncogene that inhibits protein phosphatase 2A (PP2A) and stabilizes c-Myc in cancer cells. To investigate the potential oncogenic role and prognostic value of CIP2A, we comprehensively analyzed the CIP2A expression levels in pan-cancer and observed high expression level of CIP2A in majority cancer types, including hepatocellular carcinoma (HCC). Based on a validation cohort including 60 HCC and 20 non-tumorous tissue samples, we further confirmed the high mRNA and protein expression levels of CIP2A in HCC, and found high CIP2A mRNA expression level was associated with unfavorable overall and recurrence-free survival in patients with HCC. Mechanistic investigations revealed that inhibition of CIP2A significantly attenuated cellular proliferation in vitro and tumourigenicity in vivo. Bioinformatic analysis suggested that CIP2A might be involved in regulating cell cycle. Our experimental data further confirmed CIP2A knockdown induced cell cycle arrest at G1 phase. We found accumulated cellular senescence in HCC cells with CIP2A knockdown, companying expression changes of senescence associated proteins (p21, CDK2, CDK4, cyclin D1, MCM7 and FoxM1). Mechanistically, CIP2A knockdown repressed FoxM1 expression and induced FoxM1 dephosphorylation. Moreover, inhibition of PP2A by phosphatase inhibitor rescued the repression of FoxM1. Taken together, our results showed that CIP2A was highly expressed in HCC. Inhibition of CIP2A induced cell cycle arrest and promoted cellular senescence via repressing FoxM1 transcriptional activity, suggesting a potential anti-cancer target for patients with HCC. PMID- 29175330 TI - Activation of AMP-activated protein kinase by compound 991 protects osteoblasts from dexamethasone. AB - Dexamethasone (Dex) induces direct cytotoxicity to cultured osteoblasts. The benzimidazole derivative compound 991 ("C991") is a novel and highly-efficient AMP-activated protein kinase (AMPK) activator. Here, in both MC3T3-E1 osteoblastic cells and primary murine osteoblasts, treatment with C991 activated AMPK signaling, and significantly attenuated Dex-induced apoptotic and non apoptotic cell death. AMPKalpha1 knockdown (by shRNA), complete knockout (by CRISPR/Cas9 method) or dominant negative mutation (T172A) not only blocked C991 mediated AMPK activation, but also abolished its pro-survival effect against Dex in osteoblasts. Further studies showed that C991 boosted nicotinamide adenine dinucleotide phosphate (NADPH) activity and induced mRNA expression of NF-E2 related factor 2 (Nrf2)-regulated genes (heme oxygenase-1 and NADPH quinone oxidoreductase 1). Additionally, C991 alleviated Dex-induced reactive oxygen species (ROS) production in osteoblasts. Notably, genetic AMPK inhibition reversed the anti-oxidant actions by C991 in Dex-treated osteoblasts. Together, we conclude that C991 activates AMPK signaling to protect osteoblasts from Dex. PMID- 29175331 TI - Involvement of TRPV3 and TRPM8 ion channel proteins in induction of mammalian cold-inducible proteins. AB - Cold-inducible RNA-binding protein (CIRP), RNA-binding motif protein 3 (RBM3) and serine and arginine rich splicing factor 5 (SRSF5) are RNA-binding proteins that are transcriptionally upregulated in response to moderately low temperatures and a variety of cellular stresses in mammalian cells. Induction of these cold inducible proteins (CIPs) is dependent on transient receptor potential (TRP) V4 channel protein, but seems independent of its ion channel activity. We herein report that in addition to TRPV4, TRPV3 and TRPM8 are necessary for the induction of CIPs. We established cell lines from the lung of TRPV4-knockout (KO) mouse, and observed induction of CIPs in them by western blot analysis. A TRPV4 antagonist RN1734 suppressed the induction in wild-type mouse cells, but not in TRPV4-KO cells. A TRPV3 channel blocker S408271 and a TRPM8 channel blocker AMTB as well as siRNAs against TRPV3 and TRPM8 suppressed the CIP induction in mouse TRPV4-KO cells and human U-2 OS cells. A TRPV3 channel agonist 2-APB induced CIP expression, but camphor did not. Neither did a TRPM8 channel agonist WS-12. These results suggest that TRPV4, TRPV3 and TRPM8 proteins, but not their ion channel activities are necessary for the induction of CIPs at 32 degrees C. Identification of proteins that differentially interact with these TRP channels at 37 degrees C and 32 degrees C would help elucidate the underlying mechanisms of CIP induction by hypothermia. PMID- 29175332 TI - Ankyrin repeats as a dimerization module. AB - Legionella pneumophila is a pathogen, causing severe pneumonia in humans called Legionnaires' disease. AnkC (LegA12) is a poorly characterized 495-residue effector protein conserved in multiple Legionella species. Here, we report the crystal structure of a C-terminally truncated AnkC (2-384) at 3.2 A resolution. The structure shows seven ankyrin repeats (ARs) with unique structural features. AnkC forms a dimer along the outer surface of loops between ARs. The dimer exists both in the crystal form and in solution, as shown by analytical ultracentrifugation. This is the first example of ARs as a dimerization module as opposed to solely a protein interaction domain. In addition, a novel alpha-helix insert between AR3-AR4 is positioned across the surface opposite the ankyrin groove. Sequence conservation suggests that the ankyrin groove of AnkC is a functional site that interacts with binding targets. This ankyrin domain structure is an important step towards a functional characterization of AnkC. PMID- 29175333 TI - Distinct roles of Rheb and Raptor in activating mTOR complex 1 for the self renewal of hematopoietic stem cells. AB - The mammalian target of rapamycin (mTOR) complex 1 (mTORC1) senses a cell's energy status and environmental levels of nutrients and growth factors. In response, mTORC1 mediates signaling that controls protein translation and cellular metabolism. Although mTORC1 plays a critical role in hematopoiesis, it remains unclear which upstream stimuli regulate mTORC1 activity in the context of hematopoietic stem cells (HSC) maintenance in vivo. In this study, we investigated the function of Rheb, a critical regulator of mTORC1 activity controlled by the PI3K-AKT-TSC axis, both in HSC maintenance in mice at steady state and in HSC-derived hematopoiesis post-transplantation. In contrast to the severe hematopoietic dysfunction caused by Raptor deletion, which completely inactivates mTORC1, Rheb deficiency in adult mice did not show remarkable hematopoietic failure. Lack of Rheb caused abnormalities in myeloid cells but did not have impact on hematopoietic regeneration in mice subjected to injury by irradiation. As previously reported, Rheb deficiency resulted in defective HSC derived hematopoiesis post-transplantation. However, while Raptor is essential for HSC competitiveness in vivo, Rheb is dispensable for HSC maintenance under physiological conditions, indicating that the PI3K-AKT-TSC pathway does not contribute to mTORC1 activity for sustaining HSC self-renewal activity at steady state. Thus, the various regulatory elements that impinge upstream of mTORC1 activation pathways are differentially required for HSC homeostasis in vivo. PMID- 29175334 TI - Management of Brodie bite: Note on surgical treatment. AB - Described and illustrated by Allan G. Brodie in 1946, Brodie's syndrome corresponds to an abnormal transverse occlusal relationship in which the palatal cusps of the upper molars lie outside the vestibular cusps of their mandibular antagonists. This article covers the diagnosis, clinical presentation, etiology (and, particularly, etiopathogenesis) and evolution of this syndrome, and also its management, which is often difficult. The main limitations and difficulties of orthodontics and surgery are presented, along with the surgical techniques used. These points are illustrated by some clinical cases highlighting the importance of three-dimensional analyses and 3D planning. PMID- 29175335 TI - ? PMID- 29175336 TI - Simultaneous flow cytometric immunophenotyping of necroptosis, apoptosis and RIP1 dependent apoptosis. AB - Flow cytometry was been widely used to measure apoptosis for many decades but the researcher has no definitive way of determining other forms of cell death using this technology. The use of Western Blot technology has numerous drawbacks in that all the cells in the sample whether live, dead or maybe undergoing multiple discrete forms of cell death are analysed as one population. Flow cytometry given that it can analyse different sub-populations of cells within a sample would reveal the expression of cell death markers within these sub-populations rather than just give a single result from the entire population. Here we describe a flow cytometric assay fully realising that potential by the use of anti-RIP-3 (Receptor-interacting serine/threonine-protein kinase 3) and anti-active caspase 3 fluorescently tagged antibodies and a fixable live dead fluorescent dye. This allows the determination of the degree of necroptosis, apoptosis and RIP1 dependent apoptosis within live and dead populations. Necroptosis was identified by the up-regulation of RIP3, while RIP1-dependent apoptosis was described by double positive for RIP3/active Caspase-3 events in live and dead populations. Apoptotic cells were defined by an active-Caspase-3+ve/RIP3-ve phenotype. Pan caspase blocker zVAD and RIP1 inhibitors GSK'481 or necrostatin-1 revealed interesting modulations of such sub-populations of Jurkat cells. This novel flow cytometric assay employing two antibodies and a fixable viability probe provides the researcher with in-depth analysis of various forms of regulated forms of cell death beyond what is currently available and is a major methodological advancement in this field. PMID- 29175337 TI - Unraveling complex nanoscale lipid dynamics in simple model biomembranes: Insights from fluorescence correlation spectroscopy in super-resolution stimulated emission depletion mode. AB - Dynamic heterogeneity (DH) at nanoscale due to lipid-lipid and/or lipid-protein interactions in cell membranes plays a crucial role in determining a broad range of important cell functions. In cell membranes, the dimensions of these nanodomains have been postulated to be in the order of 10's of nm and transient in nature. While the structural features of membranes have been studied in detail, little is known about their dynamical characteristics due to paucity of techniques which can probe nanoscale phenomena with simultaneous high temporal resolution. A combination of super-resolution stimulated emission depletion (STED) and fluorescence correlation spectroscopy (FCS) technique can overcome this limitation and provide information about the nanoscale dynamic heterogeneity in cell membranes. Using STED-FCS and FCS diffusion law, we provide an understanding of how nanoscale dynamically organizing lipid platforms can emerge in minimal system of model biomembranes. To illustrate the utility of the technique we have chosen cholesterol containing supported lipid bilayers and demonstrated the role of cholesterol concentration and/or added pore-forming protein, Listeriolysin O (LLO) in determining onset of lipid DH. In addition we have also looked at multi-component lipid bilayers with and without cholesterol to infer about the role of phospholipid and cholesterol composition on lipid dynamics. These results on simple biomimetic systems provide insights into fundamental pathways for the emergence of complex nanodomain substructures with implications for a wide variety of membrane mediated cellular events and depict the significant contribution that STED-FCS can make in resolving several outstanding issues in membrane biology. PMID- 29175339 TI - Molecular mechanisms of deformability of Plasmodium-infected erythrocytes. AB - In physiological conditions, normal erythrocytes are highly deformable due to their high surface area to volume ratio, their moderate cytoplasmic viscosity and the elasticity of their membrane skeleton. Infection with the human malaria parasite Plasmodium falciparum induces dramatic changes in cellular deformability and membrane elasticity of their host erythrocyte, in part due to the shape and the volume of the parasite itself, and to the export of parasite proteins that interact with host membrane skeletal proteins. These changes in deformability are tightly regulated by the parasite and may reflect a strategy to adapt to mechanical constraints encountered by the parasite in the human host. The molecular mechanisms underpinning regulation of deformability of P. falciparum infected erythrocytes are multifactorial and are being elucidated. PMID- 29175338 TI - Host-microbe interactions: commensal fungi in the gut. AB - Fungi are ubiquitous microbes that are common in diverse environments including as commensal organisms on the human body. In addition to its obvious role as a digestive organ, the intestines have been further appreciated as important for the development, maintenance, and instruction of the immune system. The gut harbors many types of microorganisms including bacteria, archaea, fungi, and viruses, and many studies over the past couple of decades have documented an important role for intestinal bacteria in immunological function. Recent studies are now suggesting that intestinal fungi (the gut 'mycobiome') may similarly play important roles in host immunity and inflammation. This review will discuss recent studies that will influence our growing understanding of the role(s) of intestinal fungi in health and disease. PMID- 29175340 TI - Membrane trafficking and remodeling at the host-parasite interface. AB - Membrane shape is functionally linked with many cellular processes. The limiting membrane of vacuoles containing Toxoplasma gondii and Plasmodium apicomplexan parasites lies at the host-parasite interface. This membrane comprises intra vacuolar and extra-vacuolar tubulo-vesicular deformations, which influence host parasite cross-talk. Here, underscoring specificities and similarities between the T. gondii and Plasmodium contexts, we present recent findings about vacuolar membrane remodeling and its potential roles in parasite fitness and immune recognition. We review in particular the implication of tubulo-vesicular structures in trapping and/or transporting host and parasite components. Understanding how membrane remodeling influences host-pathogen interactions is expected to be critical in the battle against many intracellular pathogens beyond parasites. PMID- 29175341 TI - Forecasting the burden of type 2 diabetes mellitus in Qatar to 2050: A novel modeling approach. AB - AIMS: We developed and demonstrated a novel mathematical modeling approach to forecast the burden of type 2 diabetes mellitus (T2DM) and to investigate T2DM epidemiology for the purpose of informing public health policy and programming. METHODS: A population-level compartmental mathematical model was constructed and applied to Qatar. The model was stratified according to sex, age group, risk factor status, and T2DM status, and was parameterized by nationally representative data. RESULTS: T2DM prevalence increased from 16.7% in 2012 to at least 24.0% by 2050. The rise in T2DM was most prominent among 45-54 years old. T2DM health expenditure was estimated to increase by 200-600% and to account for up to 32% of total health expenditure by 2050. Prevalence of obesity, smoking, and physical inactivity was predicted to increase from 41.4% to 51.0%, from 16.4% to 19.4%, and from 45.9% to 53.0%, respectively. The proportion of T2DM incidence attributed to obesity, smoking and physical inactivity was estimated at 57.5%, 1.8%, and 5.4%, respectively in 2012, and 65.7%, 2.1%, and 6.0%, respectively in 2050. Exploring different scenarios for the trends in risk factors, T2DM prevalence reached up to 37.7% by 2050. CONCLUSIONS: Using our innovative approach, a rising T2DM epidemic is predicted to continue in the next decades, driven by population growth, ageing and adverse trends in risk factors. Obesity was the principal risk factor explaining two-thirds of T2DM incidence. T2DM must be a national priority addressed by preventive and therapeutic interventions targeting T2DM and its modifiable risk factors. PMID- 29175342 TI - A new preparation strategy for surface modified PLA nanoparticles to enhance uptake by endothelial cells. AB - Nanoparticles are promising drug delivery systems to overcome physiological barriers such as the blood-brain barrier. In this respect nanoparticle uptake into endothelial or epithelial cells is the first necessary step to overcome these obstacles. Therefore, a new strategy for the covalent attachment of drug targeting ligands on poly(lactic acid) (PLA) nanoparticles was developed and the influence of the resulting surface properties on the uptake behaviour in cerebral endothelial cells was investigated. PLA nanoparticles were modified on their surface by apolipoprotein E, penetratin, or ovalbumin using a newly developed vinyl sulfone-modified poly(vinyl alcohol)-derivative (VS-PVA) as steric stabilizer. With this approach an easy option for ligand coupling reactions to PVA-stabilized nanoparticles was achieved. All obtained formulations showed a favourable behaviour concerning cytotoxic effects on endothelial cells, not compromising their viability. Furthermore, a clear relation between cellular uptake and surface coupled functional ligand could be determined: Penetratin- and apolipoprotein E-modified nanoparticles showed a distinct higher cellular uptake than ovalbumin-modified or unmodified nanoparticles, which both can be explained by mechanistic reasons. Overall the use of the reactive VS-PVA as stabilizer for nanoparticle preparation is an universal and effective approach to couple several functional ligands to the particles' surface for targeting applications. PMID- 29175343 TI - Diffuse sources of contamination in freshwater fish: Detecting effects through active biomonitoring and multi-biomarker approaches. AB - Aquatic organisms are usually exposed to a mixture of xenobiotics that may exert a large effect even in low concentrations, and when information is obtained exclusively from chemical analyses the prediction of the deleterious effects is potentially hindered. Therefore, the application of complementary monitoring methods is a priority. Here, in addition to chemical analyses, an active biomonitoring study using multiple biomarker responses in Nile tilapia Oreochromis niloticus was conducted to assess the effects of a contamination gradient along four reservoirs in Iguacu River. Chemical analysis in the muscle showed high levels of metals in fish from the reservoir closest to an industrialized and environmentally degraded area, however fish exposed to all studied reservoirs showed hepatic alterations (necrosis and inflammatory processes). Also, significant variations of biochemical biomarkers were observed with no clear indication of contamination gradient, since an indicative of higher impact was found in an intermediary reservoir, including high concentrations of biliary polycyclic aromatic hydrocarbons (PAHs). However, nuclear morphological alterations (NMA) were less frequent at the same reservoir. Thus, the multi biomarker approach allied to active biomonitoring is a practical and important tool to assess deleterious effects of contamination in freshwater, providing data for monitoring and conservation protocols. PMID- 29175344 TI - Inoculation of soil with an Isoproturon degrading microbial community reduced the pool of "real non-extractable" Isoproturon residues. AB - During pesticides degradation, biogenic non-extractable residues ("apparent NER") may not share the same environmental fate and risks with the "real NER" that are bound to soil matrix. It is not clear how microbial community (MC) inoculation for pesticides degradation would influence the NER composition. To investigate degradation efficiency of pesticides Isoproturon (IPU) and NER composition following MC inoculation, clay particles harboring MC that contains the IPU degrading strain, Sphingomonas sp., were inoculated into soil receiving 14C labeled IPU addition. Mineralization of IPU was greatly enhanced with MC inoculation that averagely 55.9% of the applied 14C-IPU was consumed up into 14CO2 during 46 days soil incubation. Isoproturon degradation was more thorough with MC than that in the control: much less amount of metabolic products (4.6% of applied IPU) and NER (35.4%) formed in MC treatment, while the percentages were respectively 30.3% for metabolites and 49.8% for NER in the control. Composition of NER shifted with MC inoculation, that relatively larger amount of IPU was incorporated into the biogenic "apparent NER" in comparison with "real NER". Besides its well-recognized role on enhancing mineralization, MC inoculation with clay particles benefits soil pesticides remediation in term of reducing "real NER" formation, which has been previously underestimated. PMID- 29175345 TI - Quaternary ammonium cationic surfactants increase bioactivity of indoxacarb on pests and toxicological risk to Daphnia magna. AB - Agricultural researchers have always been pursuing synergistic technique for pest control. To evaluate the combined effects of quaternary ammonium compounds (QACs) and indoxacarb, their independent and joint toxicities to two insects, Spodoptera exigua and Agrotis ipsilon, and the aquatic organism, Daphnia magna, were determined. Results showed that all of five tested QACs increased the toxicity of indoxacarb to S. exigua and A. ipsilon. Both of benzyldimethyltetradecylammonium chloride (TDBAC) and benzododecinium chloride (DDBAC) exhibited significantly increased toxicities to S. exigua with synergic ratios of 11.59 and 6.55, while that to A. ipsilon were 2.60 and 3.45, respectively. When exposed to binary mixtures of QACs and indoxacarb, there was synergism on D. magna when using additive index and concentration addition methods, but only TDBAC, STAC and ODDAC showed synergistic effect in the equivalent curve method. The results indicate that the surfactants can be used as the synergists of indoxacarb in the control of Lepidoptera pests. However, their environmental risks should not be neglected owing to the high toxicity of all mixtures of indoxacarb and five QACs to D. magna.

AB - Endocrine disrupting compounds (EDCs) can be found in domestic sewage, wastewater treatment plant effluents, natural water, rivers, lakes and in the marine environment. Jurujuba Sound, located in the state of Rio de Janeiro, Southeastern Brazil, receives untreated sewage into its waters, one the main sources of aquatic contamination in this area. In this context, the aim of the present study was to evaluate the estrogenic potential of water sampled from different depths and from areas with differential contamination levels throughout Jurujuba Sound. Water quality was evaluated and acute toxicity assays using Allviibrio fischeri were conducted, while estrogenic activity of the water samples was determined by a Yeast Estrogen Screening assay (YES). Water quality was mostly within the limits established for marine waters by the Brazilian legislation, with only DOC and ammoniacal nitrogen levels above the maximum permissible limits. No acute toxicity effects were observed in the Allivibrio fisheri assay. The YES assay detected moderate estrogenic activity in bottom water samples from 3 sampling stations, ranging from 0.5 to 3.2ngL-1, as well as in one surface water sample. Estrogenic activity was most frequently observed in samples from the bottom of the water column, indicating adsorption of estrogenic compounds to the sediment.

AB - pH variation could cause a stress response in euryhaline penaeids, we evaluated the mortality, growth performance, osmoregulation gene expression, digestive enzyme activity, histology, and resistance against Vibrio parahemolyticus of white shrimp Litopenaeus vannamei reared under conditions of gradual changes to a low-pH environment (gradual-low pH, 6.65-8.20) or a high-pH environment (gradual high pH, 8.20-9.81) versus a normal pH environment (8.14-8.31) during a 28-d experiment. Consequently, under gradual-high pH, the cumulative mortality rate (CMR) rose with time until 39.9% on days 28; the weight gain percentage (WGP) and length gain percentage (LGP) decreased continuously. However, under gradual-low pH, the CMR of shrimp stabilized at 6.67% during 7-28 d; the WGP and LGP decreased first and then returned to normal. These results indicated that L. vannamei displayed a moderate tolerance to gradual-low pH, compared with gradual high pH. Under gradual-low pH, the Na+/K+-ATPase, cytoplasmic carbonic anydrase (CAc), and glycosyl-phosphatidylinositol-linked carbonic anhydrase (CAg) transcripts of shrimp increased continuously or then back to normal; the amylase, lipase, and trypsin activities decreased first and then returned to normal or increased; the hepatopancreases and midguts showed histopathological lesions first and then got remission. Thus, the major adaptation mechanism of shrimp to gradual-low pH might be its high osmoregulation ability, which made shrimp achieve a new, balanced steady-state, then promoted longer intestinal villi and recuperative hepatopancreases of shrimp with enhanced digestive enzyme activities to increase nutrient absorption after long-term exposure. Meanwhile, the enhanced resistance against V. parahemolyticus under gradual-low pH would probably inhibit disease outbreak in the shrimp farming. PMID- 29175348 TI - Safety of methionine, a novel biopesticide, to adult and larval honey bees (Apis mellifera L.). AB - Methionine is an essential/indispensible amino acid nutrient required by adult and larval honey bees (Apis mellifera L. [Hymenoptera: Apidae]). Bees are unable to rear broods on pollen deficient in methionine, and reportedly behaviorally avoid collecting pollen or nectar from florets deficient in methioinine. In contrast, it has been demonstrated that methionine is toxic to certain pest insects; thus it has been proposed as an effective biopesticide. As an ecofriendly integrated pest management agent, methionine boasts a novel mode of action differentiating it from conventional pesticides, while providing non target safety. Pesticides that minimize collateral effects on bees are desirable, given the economic and ecological concerns about honey bee health. The aim of the present study was to assess the potential impact of the biopesticide methionine on non-target adult and larval honey bees. Acute contact adult toxicology bioassays, oral adult assessments and chronic larval toxicity assessments were performed as per U.S. Environmental Protection Agency (EPA) requirements. Our results demonstrated that methionine fits the U.S. EPA category of practically nontoxic (i.e. lethal dose to 50% mortality or LD50 > 11ug/bee) to adult honey bees. The contact LD50 was > 25ug/bee and the oral LD50 was > 100ug/bee. Mortality was observed in larval bees that ingested DL-methionine (effective concentration to 50% mortality or EC50 560ug/bee). Therefore, we conclude that methionine poses little threat to the health of the honey bee, due to unlikely exposure at concentrations shown to elicit toxic effects.

PMID- 29175351 TI - Prevalence, associated factors, outcomes and transmission of extensively drug resistant tuberculosis among multidrug-resistant tuberculosis patients in Sao Paulo, Brazil: a cross-sectional study. AB - OBJECTIVES: To describe the prevalence, associated factors, treatment outcomes and transmission of extensively drug-resistant (XDR) tuberculosis (TB) in the state of Sao Paulo, Brazil, for 2011 to 2013. METHODS: Drug susceptibility testing to first- and second-line drugs was performed by BACTEC MGIT 960 and molecular typing, by IS6110 restriction fragment length polymorphism. Clinical, epidemiologic and demographic data were obtained from surveillance information systems for TB. Patients were divided into three groups: multidrug resistant (MDR) TB (resistance to at least isoniazid and rifampicin), pre-XDR-TB (MDR-TB resistant to a fluoroquinolone or to at least one of the second-line injectable drugs) and XDR-TB (MDR-TB resistant to a fluoroquinolone and to at least one of the second-line injectables). RESULTS: Among the 313 MDR-TB patients identified, the prevalence of XDR-TB and pre-XDR-TB was 10.2% (n = 32) and 19.2% (n = 60), respectively. Compared to MDR-TB patients, XDR-TB patients were more likely to be female (odds ratio (OR) = 2.74, 95% confidence interval (CI), 1.29-5.83), have a history of TB (OR = 5.16; 95% CI, 1.52-17.51) and present higher death rates (OR= 3.74; 95% CI 1.70-8.25). XDR-TB transmission was observed in households, between neighbours and between a patient and a healthcare worker in a hospital. CONCLUSIONS: The prevalence of XDR-TB in the state of Sao Paulo is close to that estimated globally. Most of the XDR-TB patients were treated previously for TB and presented the lowest successful outcome rates. Because transmission of XDR-TB occurred, it is important that timely diagnosis of drug resistance is performed. PMID- 29175353 TI - Classification of instability after reverse shoulder arthroplasty guides surgical management and outcomes. AB - BACKGROUND: Revision of unstable reverse shoulder arthroplasty (RSA) remains a significant challenge. The purpose of this study was to determine the reliability of a new treatment-guiding classification for instability after RSA, to describe the clinical outcomes of patients stabilized operatively, and to identify those with higher risk of recurrence. METHODS: All patients undergoing revision for instability after RSA were identified at our institution. Demographic, clinical, radiographic, and intraoperative data were collected. A classification was developed using all identified causes of instability after RSA and allocating them to 1 of 3 defined treatment-guiding categories. Eight surgeons reviewed all data and applied the classification scheme to each case. Interobserver and intraobserver reliability was used to evaluate the classification scheme. Preoperative clinical outcomes were compared with final follow-up in stabilized shoulders. RESULTS: Forty-three revision cases in 34 patients met the inclusion for study. Five patients remained unstable after revision. Persistent instability most commonly occurred in persistent deltoid dysfunction and postoperative acromial fractures but also in 1 case of soft tissue impingement. Twenty-one patients remained stable at minimum 2 years of follow-up and had significant improvement of clinical outcome scores and range of motion. Reliability of the classification scheme showed substantial and almost perfect interobserver and intraobserver agreement among all the participants (kappa = 0.699 and kappa = 0.851, respectively). DISCUSSION: Instability after RSA can be successfully treated with revision surgery using the reliable treatment-guiding classification scheme presented herein. However, more understanding is needed for patients with greater risk of recurrent instability after revision surgery. PMID- 29175352 TI - Behavioral and biochemical sensitivity to low doses of ketamine: Influence of estrous cycle in C57BL/6 mice. AB - RATIONALE: Low-dose ketamine is a rapid-acting antidepressant, to which female rodents are more sensitive as compared to males. However, the mechanism mediating this sex difference in ketamine sensitivity remains elusive. OBJECTIVES: We sought to determine whether male and female mice differ in their behavioral sensitivity to low doses of ketamine, and uncover how ovarian hormones influence females' ketamine sensitivity. We also aimed to uncover some of the molecular mechanism(s) in mood-related brain regions that mediate sex differences in ketamine antidepressant effects. METHODS: Male and female mice (freely-cycling, diestrus 1 [D1], proestrus [Pro], or D1 treated with an estrogen receptor (ER) alpha, ERbeta, or progesterone receptor (PR) agonist) received ketamine (0, 1.5, or 3 mg/kg, intraperitoneally) and were tested in the forced swim test (FST) 30 min later. Ketamine's influence over synaptic plasticity markers in the prefrontal cortex (PFC) and hippocampus (HPC) of males, D1, and Pro females was quantified by Western blot 1 h post-treatment. RESULTS: Males, freely cycling females, D1 and Pro females exhibited antidepressant-like responses to 3 mg/kg ketamine. Pro females were the only group where ketamine exhibited an antidepressant effect at 1.5 mg/kg. D1 females treated with an agonist for ERalpha or ERbeta exhibited an antidepressant-like response to 1.5 mg/kg ketamine. Ketamine (3 mg/kg) increased synaptic plasticity-related proteins in the PFC and HPC of males, D1, and Pro females. Yet, Pro females exhibited an increase in p-Akt and p-CaMKIIalpha in response to 1.5 and 3 mg/kg ketamine. CONCLUSION: Our results indicate that females' enhanced sensitivity to ketamine during Pro is likely mediated through estradiol acting on ERalpha and ERbeta, leading to greater activation of synaptic plasticity-related kinases within the PFC and HPC. PMID- 29175354 TI - Interaction of defibrillation waveform with the time to defibrillation or the number of defibrillation attempts on survival from out-of-hospital cardiac arrest. AB - AIM: Early biphasic defibrillation is effective in out-of-hospital cardiac arrest (OHCA) cases. In the resuscitation of patients with OHCA, it is not clear how the defibrillation waveform interacts with the time to defibrillation to influence patient survival. The second, and any subsequent, shocks need to be administered by an on-line physician in Japan. Thus, we investigated the interaction between the defibrillation waveform and time to or the number of defibrillation on resuscitation outcomes. METHODS: This prospective observational study used data for all OHCAs that occurred between 2005 and 2014 in Japan. To investigate the interaction effect between the defibrillation waveform and the time to defibrillation or the number of defibrillations on the return to spontaneous circulation (ROSC), 1-month survival, and cerebral performance category (CPC) (1, 2), we assessed the modifying effects of the defibrillation waveform and the time to or the number of defibrillation on additive scale (i.e., the relative excessive risk due to interaction, RERI) and multiplicative scale (i.e., ratio of odds ratios (ORs)). RESULTS: In total, 71,566 cases met the inclusion criteria. For the measure of interaction between the defibrillation waveform and the time to defibrillation, ratio of ORs for ROSC was 0.84 (0.75-0.94), implying that the effect of time to first defibrillation on ROSC was negatively modified by defibrillation waveform. For the interaction between the defibrillation waveform and the number of defibrillations, RERI and ratio of ORs for CPC (1, 2) was -0.25 (-0.47 to -0.06) and 0.79 (0.67-0.93), respectively. It is implied that the effect of number of defibrillation on CPC (1, 2) was negatively modified by defibrillation waveform. CONCLUSIONS: An increased number of defibrillations was associated with a decreased ROSC in the case of biphasic and monophasic defibrillation, while an increased number of defibrillations was related to an increased 1-month survival rate and CPC (1, 2) only in the case of biphasic defibrillation. When two or more defibrillations were performed, a biphasic waveform was more effective in terms of long-term survival than a monophasic waveform. PMID- 29175355 TI - An assessment of ventilation and perfusion markers in out-of-hospital cardiac arrest patients receiving mechanical CPR with endotracheal or supraglottic airways. AB - AIM OF THE STUDY: Mechanical chest compression (MCPR) devices are considered equivalent to manual compressions in patient outcomes in out-of-hospital cardiac arrest (OHCA). However, recent data suggest possible harm in patients with a supraglottic airway device (SGA) during MCPR. The aim of this study was to evaluate differences in direct and indirect markers of ventilation and perfusion in patients with cardiac arrest receiving MCPR and who had their airway managed with an endotracheal tube (ETT) or SGA. METHODS: We retrospectively reviewed Emergency Medical Services (EMS) agencies and emergency department (ED) records over a two-year period. We included patients with OHCA who underwent MCPR and who had an advanced airway placed. The primary outcome was differences in intra arrest end-tidal carbon dioxide (etCO2) measurements. Secondary outcomes included intra-arrest ventilation rates, rates of prehospital return of spontaneous circulation (ROSC), blood pressure upon prehospital ROSC, and 24-h survival. RESULTS: Valid data sets were available for 126 patients. Eighty-four (66.7%) had an ETT placed, and 42 (33.3%) had a SGA placed. Twenty-eight (22.6%) achieved prehospital ROSC. Twenty-four-hour survival data were available for 13 (10.3%) of these patients. There were no significant differences in primary or secondary outcomes. CONCLUSION: In this retrospective study, we found no evidence of differences in markers of ventilation, perfusion or prehospital ROSC and survival in patients with OHCA who had their airway managed with either an ETT or SGA while receiving MCPR. PMID- 29175356 TI - Point-of-care ultrasound use in patients with cardiac arrest is associated prolonged cardiopulmonary resuscitation pauses: A prospective cohort study. AB - OBJECTIVE: We aim to evaluate if point-of-care ultrasound use in cardiac arrest is associated with CPR pause duration. METHODS: This is a prospective cohort study of patients with cardiac arrest (CA) presenting to an urban emergency department from July 2016 to January 2017. We collected video recordings of patients with CA in designated code rooms with video recording equipment. The CAs recordings were reviewed and coded by two abstractors. The primary outcome was the difference CPR pause duration when POCUS was and was not performed. RESULTS: A total of 110 CPR pauses were evaluated during this study. The median CPR pause with POCUS performed lasted 17s (IQR 13 - 22.5) versus 11s (IQR 7 - 16) without POCUS. In addition, multiple regression analysis demonstrated that POCUS was associated with longer pauses (6.4s, 95%CI 2.1- 10.8); ultrasound fellowship trained faculty trended towards shorter CPR pauses (-4.1s, 95%CI -8.8-0.6) compared to non-ultrasound fellowship trained faculty; and when the same provider led the resuscitation and performed the POCUS, pause durations were 6.1s (95%CI 0.4 -11.8) longer than when another provider performed the POCUS. CONCLUSION: In this prospective cohort trial of 24 patients with CA, POCUS during CPR pauses was associated with longer interruptions in CPR.

PMID- 29175357 TI - Hemodynamic effects of IV sodium nitrite in hospitalized comatose survivors of out of hospital cardiac arrest. AB - BACKGROUND: Patients resuscitated from cardiac arrest have brain and cardiac injury. Recent animal studies suggest that the administration of sodium nitrite after resuscitation from 12min of asystole limits acute cardiac dysfunction and improves survival and neurologic outcomes. It has been hypothesized that low doses of IV sodium nitrite given during resuscitation of out of hospital cardiac arrest (OHCA) will improve survival. Low doses of sodium nitrite (e.g., 9.6mg of sodium nitrite) are safe in healthy individuals, however the effect of nitrite on blood pressure in resuscitated cardiac arrest patients is unknown. METHODS: We performed a single-center, pilot trial of low dose sodium nitrite (1 or 9.6mg dose) vs. placebo in hospitalized out-of-hospital cardiac arrest patient to determine whether nitrite administration reduced blood pressure and whether whole blood nitrite levels increased in response to nitrite administration. RESULTS: This is the first reported study of sodium nitrite in cardiac arrest patients. Infusion of low doses of sodium nitrite in comatose survivors of OHCA (n=7) compared to placebo (n=4) had no significant effects on heart rate within 30min after infusion (70+/-20 vs. 78+/-3 beats per minute, p=0.18), systolic blood pressure (103+/-20 vs 108+/-15mmHg, p=0.3), or methemoglobin levels (0.92+/-0.33 vs. 0.70+/-0.26, p=0.45). Serum nitrite levels of 2-4MUM were achieved within 15min of a 9.6mg nitrite infusion. CONCLUSIONS: Low dose sodium nitrite does not cause significant hemodynamic effect in patients with OHCA, which suggests that nitrite can be delivered safely in this critically ill patient population. Higher doses of sodium nitrite are necessary in order to achieve target serum level of 10MUM. PMID- 29175359 TI - Trial Duration and Risk Reduction in Combination Therapy Trials for Pulmonary Arterial Hypertension: A Systematic Review. AB - BACKGROUND: Relative risk (RR) and number needed-to-treat (NNT) are frequently time-dependant measures. We performed a systematic review and meta-analysis to assess whether trial duration influenced the relative and absolute risk of worsening in randomized controlled trials (RCTs) comparing combination therapy (CT) of pulmonary arterial hypertension (PAH)-specific therapies vs monotherapy (MT). METHODS: We searched MEDLINE, Embase, and the Cochrane Library (January 1990 to September 2016) for RCTs assessing CT compared with MT in PAH. The primary outcome was the risk of clinical worsening. We assessed whether trial duration correlated with RR and NNT using weighted meta-regression with mixed effects. Changes in NNT overtime were also assessed using data from long-term event-driven trials. RESULTS: There were 3,801 patients throughout 15 studies included. The RR for clinical worsening positively correlated with trial duration (R2 = 0.67, P = .0002), whereas the NNT did not (mean NNT, 7; R2 = 0.02; P = .65). Among long-term event-driven trials, the mean NNT progressively decreased until 52 weeks of follow-up, being stable thereafter. Conversely, the mean RR progressively increased from approximately 0.40 at week 16 to approximately 0.68 at week 104. CONCLUSIONS: Absolute risk reduction of clinical worsening was relatively constant beyond 6 to 12 months of treatment in clinical trials comparing CT with MT in PAH. These results question the need for CT trials of very long duration in PAH. PMID- 29175360 TI - Efficacy of Acupuncture Is Noninferior to Nicotine Replacement Therapy for Tobacco Cessation: Results of a Prospective, Randomized, Active-Controlled Open Label Trial. AB - BACKGROUND: We designed and conducted this multicenter randomized active controlled open-label trial to evaluate the efficacy of acupuncture, auricular point pressing, and nicotine replacement therapy (NRT) on tobacco cessation in the Chinese population. METHODS: This randomized controlled trial was conducted in seven hospitals in China between October 2013 and February 2016. Eligible participants were recruited and randomly assigned to receive acupuncture or auricular point pressing or NRT via a central randomization system with a 1:1:1 ratio. All treatment was given for a total of 8 weeks, and follow-up visit was at 16 weeks. The primary outcome measure was carbon monoxide (CO)-confirmed 24-h point abstinence rate (<10 parts per million), 24 weeks after quit day. RESULTS: A total of 300 participants were recruited and 195 participants finished, with a dropout rate of 35.00%. Two cases of adverse events in the acupuncture group and 2 cases in the NRT group were observed. The CO-confirmed 24-h point abstinence rate was 43.00% at 24 weeks in the acupuncture group, which was similar to 44.00% in the NRT group (P > .05), but significantly higher than the 30.00% in the auricular point group (P < .05). At 24 weeks, the Fagerstrom Nicotine Dependence Test and the Minnesota Nicotine Withdrawal Scale scores in the acupuncture group were significantly lower than those in the auricular point group and in the NRT group (P < .05). Kaplan-Meier analysis showed the time to relapse for acupuncture (44.12 days) was insignificantly longer than NRT (41.18 days), but significantly longer than auricular point pressing (29.53 days). CONCLUSIONS: We found acupuncture was safe and a possible treatment for tobacco cessation, but it requires further study to establish its role.

PMID- 29175362 TI - Systematic review and meta-analyses of useful field of view cognitive training. AB - Systematic review and meta-analyses were conducted of Useful Field of View (UFOV) training, which was evaluated by Institute of Medicine criteria. Forty-four studies of UFOV training from 17 randomized trials conducted among adults were identified in systematic review. Results addressing the Institute of Medicine criteria indicated that: (a) UFOV training enhanced neural outcomes, speed of processing, and attention. (b) UFOV training effects were equivalent when compared to active- or no-contact control conditions. (c) UFOV training showed far transfer to everyday function. (d) Improvements on the trained skills endured across ten years. (e) Half of the clinical trials identified were conducted by researchers without financial interests in UFOV training. Results indicated that UFOV training effects were larger for adaptive- than non-adaptive training techniques, and in community-based as compared to clinical samples. UFOV training did not transfer to other neuropsychological outcomes, but positively enhanced well-being, health, and quality of life longitudinally. Criticisms of cognitive training are addressed. UFOV training should be implemented among older adults to improve real-world functional outcomes and well-being. PMID- 29175361 TI - The Role of Computed Tomography for the Evaluation of Lung Disease in Alpha-1 Antitrypsin Deficiency. AB - Alpha-1 antitrypsin deficiency (AATD) is characterized by low serum levels of or dysfunctional alpha-1 proteinase inhibitor. In the lung parenchyma, this results in a loss of protection against the activity of serine proteases, particularly neutrophil elastase. The resultant imbalance in protease and antiprotease activity leads to an increased risk for the development of early-onset emphysema and COPD. As in traditional smoke-related COPD, the assessment of the severity and disease progression of lung disease in AATD is conventionally based on lung function; however, pulmonary function tests are unable to discriminate between emphysema and airways disease, the two hallmark pathologic features of COPD. CT imaging has been used as a tool to further characterize lung structure and evaluate therapeutic interventions in AATD-related COPD. Moreover, recent advances in quantitative CT have significantly improved our assessment of the lung architecture, which has provided investigators and clinicians with a more detailed evaluation of the extent and severity of emphysema and airways disease in AATD. In addition, serial CT imaging measures are becoming increasingly important, as they provide a tool to monitor emphysema progression. This review describes the principles of CT technology and the role of CT imaging in assessing pulmonary disease progression in AATD, including the effect of therapeutic interventions. PMID- 29175364 TI - Open questions on the 3D structures of collagen containing vertebrate mineralized tissues: A perspective. AB - Our current understanding of the structures of vertebrate mineralized tissues is largely based on light microscopy/histology and projections of 3D structures onto 2D planes using electron microscopy. We know little about the fine details of these structures in 3D at the length scales of their basic building blocks, the inherent variations of structure within a tissue and the cell-extracellular tissue interfaces. This limits progress in understanding tissue formation, relating structure to mechanical and metabolic functions, and obtaining deeper insights into pathologies and the evolution of these tissues. In this perspective we identify and discuss a series of open questions pertaining to collagen containing vertebrate mineralized tissues that can be addressed using appropriate 3D structural determination methods. By so doing we hope to encourage more research into the 3D structures of mineralized vertebrate tissues. PMID- 29175363 TI - Bone morphogenetic protein signaling through ACVR1 and BMPR1A negatively regulates bone mass along with alterations in bone composition. AB - Bone quantity and bone quality are important factors in determining the properties and the mechanical functions of bone. This study examined the effects of disrupting bone morphogenetic protein (BMP) signaling through BMP receptors on bone quantity and bone quality. More specifically, we disrupted two BMP receptors, Acvr1 and Bmpr1a, respectively, in Osterix-expressing osteogenic progenitor cells in mice. We examined the structural changes to the femora from 3 month old male and female conditional knockout (cKO) mice using micro-computed tomography (micro-CT) and histology, as well as compositional changes to both cortical and trabecular compartments of bone using Raman spectroscopy. We found that the deletion of Acvr1 and Bmpr1a, respectively, in an osteoblast-specific manner resulted in higher bone mass in the trabecular compartment. Disruption of Bmpr1a resulted in a more significantly increased bone mass in the trabecular compartment. We also found that these cKO mice showed lower mineral-to-matrix ratio, while tissue mineral density was lower in the cortical compartment. Collagen crosslink ratio was higher in both cortical and trabecular compartments of male cKO mice. Our study suggested that BMP signaling in osteoblast mediated by BMP receptors, namely ACVR1 and BMPR1A, is critical in regulating bone quantity and bone quality. PMID- 29175365 TI - Roles of three Fusarium graminearum membrane Ca2+ channels in the formation of Ca2+ signatures, growth, development, pathogenicity and mycotoxin production. AB - Similar to animals and plants, external stimuli cause dynamic spatial and temporal changes of cytoplasmic Ca2+ in fungi. Such changes are referred as the Ca2+ signature and control cellular responses by modulating the activity or location of diverse Ca2+-binding proteins (CBPs) and also indirectly affecting proteins that interact with CBPs. To understand the mechanism underpinning Ca2+ signaling, therefore, characterization of how Ca2+ moves to and from the cytoplasm to create Ca2+ signatures under different conditions is fundamental. Three genes encoding plasma membrane Ca2+ channels in a Fusarium graminearum strain that expresses a fluorescent protein-based Ca2+ indicator in the cytoplasm were mutagenized to investigate their roles in the generation of Ca2+ signatures under different growth conditions and genetic backgrounds. The genes disrupted include CCH1 and MID1, which encode a high affinity Ca2+ uptake system, and FIG1, encoding a low affinity Ca2+ channel. Resulting mutants were also analyzed for growth, development, pathogenicity and mycotoxin production to determine how loss of each of the genes alters these traits. To investigate whether individual genes influence the function and expression of other genes, phenotypes and Ca2+ signatures of their double and triple mutants, as well as their expression patterns, were analyzed. PMID- 29175366 TI - Lack of the NAD+-dependent glycerol 3-phosphate dehydrogenase impairs the function of transcription factors Sip4 and Cat8 required for ethanol utilization in Kluyveromyces lactis. AB - The NAD+-dependent glycerol 3-phosphate dehydrogenase (KlGpd1) is an important enzyme for maintenance of the cytosolic redox balance in the milk yeast Kluyveromyces lactis. The enzyme is localized in peroxisomes and in the cytosol, indicating its requirement for the oxidation of NADH in both compartments. Klgpd1 mutants grow more slowly on glucose than wild-type cells and do not grow on ethanol as a sole carbon source. We studied the molecular basis of the latter phenotype and found that Gpd1 is required for high expression of KlICL1 and KlMLS1 which encode the key enzymes of the glyoxylate pathway isocitrate lyase and malate synthase, respectively. This regulation is mediated by CSRE elements in the promoters of these genes and the Snf1-regulated transcription factors KlCat8 and KlSip4. To study the transactivation function of these factors we developed a modified yeast one-hybrid system for K. lactis, using the endogenous beta-galactosidase gene LAC4 as a reporter in a lac9 deletion background. In combination with ChIP analyses we discovered that Gpd1 controls both the specific binding of Cat8 and Sip4 to the target promoters and the capacity of these factors to activate the reporter gene expression. We propose a model in which KlGpd1 activity is required for maintenance of the redox balance. In its absence, genes which function in generating redox balance instabilities are not expressed. A comparison of mutant phenotypes further indicates, that this system not only operates in K. lactis, but also in Saccharomyces cerevisiae. PMID- 29175367 TI - Spatial heterogeneity of glycogen and its metabolizing enzymes in Aspergillus nidulans hyphal tip cells. AB - Glycogen is a homopolymer of glucose and a ubiquitous cellular-storage carbon. This study investigated which Aspergillus nidulans genes are involved in glycogen metabolism. Gene disruptants of predicted glycogen synthase (gsyA) and glycogenin (glgA) genes accumulated less cellular glycogen than the wild type strain, indicating that GsyA and GlgA synthesize glycogen similarly to other eukaryotes. Meanwhile, gene disruption of gphA encoding glycogen phosphorylase increased the amount of glycogen to a higher degree than wild type during the stationary phase that accompanies carbon-source limitation. GFP-tagged GsyA and GphA were distributed in the cytosol and formed punctate and filamentous structures, respectively. Carbon starvation resulted in elongated GphA-GFP filaments and increased numbers of filaments. These structures were more frequently located in the basal regions of tip cells and adjacent cells than in the apical regions of tip cells. Cellular glycogen visualized by incorporation of a fluorescent glucose analog accumulated in cytoplasmic puncta that were more prevalent in the basal regions, a pattern similar to that seen for GsyA. The colocalization of glycogen and GsyA at punctate structures in tip and sub-apical cells likely represents the cellular machinery for synthesizing glycogen. More frequent colocalization in the basal, rather than tip cell apical regions indicated that tip cells have differentiated subcellular regions for glycogen synthesis. Our findings regarding glycogen, GsyA and GphA distribution evoke the spatial heterogeneity of glycogen metabolism in fungal hyphae. PMID- 29175368 TI - Active Surveillance in Small Renal Masses in the Elderly: A Literature Review. AB - CONTEXT: Small renal masses have become increasingly common due to widespread imaging; however, optimal management of these lesions in the elderly can be complex due to the competing risks of intervention, natural history of disease, patient comorbidities, and expectations. In the properly selected elderly patient, active surveillance remains an accepted and attractive treatment approach. OBJECTIVE: We completed a literature review of small renal masses (enhancing, <4cm, T1aN0M0 disease) in the elderly, aged >=70 yr, aimed at identifying the utility of active surveillance in this population. The primary outcomes were conversion to active treatment while on active surveillance and cancer-specific mortality. Secondary outcomes included predictors of treatment, type of treatment performed (partial nephrectomy, radical nephrectomy, and ablation), progression to metastases, all-cause mortality, tumor growth rate, and demographic data including age and Charlson Comorbidity Index. EVIDENCE ACQUISITION: A comprehensive search of electronic databases (e.g., MEDLINE, EMBASE, SCOPUS, Web of Science, and the Cochrane Library) using search terms "small renal mass" OR "SRM", AND "elderly," "senior," "aging," "geriatric," OR "octogenarian" was completed. All randomized controlled trials, nonrandomized comparison studies, and case series were included and screened by the reviewers. All comparison studies included in the systematic review were assessed for methodological quality using the Cochrane Risk of Bias tools. EVIDENCE SYNTHESIS: Seventeen primary studies including 36495 patients met the inclusion criteria for the systematic review. All studies were retrospective institutional chart or the Surveillance, Epidemiology, and End Results database reviews. There was a low (4 26%) rate of conversion to active treatment for active surveillance in the identified studies over a follow-up interval of up to 91.5 mo. Overall mortality was substantial in this elderly cohort, with 15-51% of patients being deceased over the course of study follow-up; however, there was minimal cancer-specific mortality due to patients succumbing to alternative comorbid disease. In the future, patient comorbidity and biological age versus the natural history of the individualized tumor biology may play an increasing role in the discussion regarding treatment options and consideration of active surveillance. CONCLUSIONS: Active surveillance is an effective management strategy in the elderly population. Few patients required the conversion to active treatment and there was low cancer-specific mortality. The majority of patients who expired over the course of the identified studies succumbed to alternative disease. The goal of treatment strategies should include weighing patient-specific prognosis relative to their competing health risks and treatment goals against the natural history of disease and risks of intervention. PATIENT SUMMARY: In this review article, the authors examined the utility of active surveillance in the setting of a small localized renal mass in the elderly population. Despite being on surveillance, we found that cancer-specific outcomes were excellent, and overall mortality was often a result of comorbid disease. However, there is significant heterogeneity among elderly patients, and treatment approaches should be focused around patient-centered goals and prognosis.

PMID- 29175370 TI - Atopy Is Associated with Age at Asthma Onset in Elderly Patients. AB - BACKGROUND: Asthma in the elderly population (60 years of age and older) is frequently underdiagnosed, as well as atopy. Atopy, although more prevalent in younger patients, can be a major cause of asthma in the elderly. Chronic obstructive pulmonary disease (COPD) and cardiovascular disease are common differential diagnoses, especially in elderly smokers. OBJECTIVE: The objective of this study was to assess atopy and comorbidities in elderly patients with asthma. METHODS: This was an observational and retrospective study involving elderly asthmatic patients followed up at a tertiary center. Patients were assessed for severity of asthma, frequency of atopy, and frequency of comorbidities concomitant with asthma. Then, they were classified according to their age at asthma onset and the groups compared with each other for atopy, spirometric parameters, and comorbidities. RESULTS: This study included 243 elderly asthmatic patients, 71.8% of them presenting severe disease and 82.3% forced expiratory volume in 1 second (FEV1) < 80%. Gastroesophageal reflux disease, obesity, and asthma-COPD overlap syndrome were observed, respectively, in 64%, 37%, and 13% of these patients. Atopy was observed in 63%, mainly in those with early onset disease, and its frequency decreased as the age of asthma onset increased (P < .05). Total serum IgE was higher for allergic patients and FEV1 values were lower for patients with long-term asthma. Aspirin-exacerbated respiratory disease was more frequent in patients with nonallergic asthma. CONCLUSIONS: Most elderly asthmatic patients followed up in our tertiary center were atopic and higher values of total serum IgE suggest atopy. Atopy was inversely correlated with age of asthma onset. The diagnosis of allergic asthma in the elderly population is essential to treat patients more properly, improving their quality of life and decreasing asthma morbidity and mortality. PMID- 29175371 TI - Natural History of Benign Nonimmediate Allergy to Beta-Lactams in Children: A Prospective Study in Retreated Patients After a Positive and a Negative Provocation Test. AB - BACKGROUND: The drug provocation test (DPT) is considered as the gold standard to diagnose drug allergy and is particularly important in the diagnosis of nonimmediate beta-lactam (BL) allergy in children. The natural history of BL allergy remains unknown. OBJECTIVE: Our main aim was to evaluate the natural history of nonimmediate BL hypersensitivity and the long-term tolerance acquisition, and our secondary objective was to determine the negative predictive value (NPV) of the DPT following a 2-day protocol. METHODS: Children developing a benign rash while treated by BL were prospectively recruited at the Emergency Department of the Geneva University Hospital from 2006 to 2011 and challenged with the incriminated BL (initial diagnostic drug provocation test [idDPT]) following a 2-day protocol. In case of a positive idDPT, the patients underwent a follow-up drug provocation test (fuDPT) 3 years later. In case of a negative idDPT, we sent a questionnaire to assess tolerance of a subsequent treatment with the incriminated BL. RESULTS: Among the 18 children with a positive idDPT, 16 children (89%) had a negative fuDPT and 2 children developed a benign exanthema. Among those 16 children, 11 tolerated a subsequent treatment with the incriminated BL without any reaction, suggesting natural antibiotic tolerance acquisition. From another point of view, we found that the NPV of the DPT following a 2-day protocol was excellent at 96.7%. CONCLUSIONS: Our data strongly suggest that a fuDPT is safe and useful to assess tolerance acquisition in children with a confirmed benign nonimmediate BL allergy. In addition, our results support the use of a short DPT protocol (2 days), which led to a high NPV of 96.7% in our population, with a favorable benefit-risk balance. PMID- 29175373 TI - Non-invasive T1rho mapping of the human cartilage response to loading and unloading. AB - OBJECTIVE: To define the physiological response to sequential loading and unloading in histologically intact human articular cartilage using serial T1rho mapping, as T1rho is considered to indicate the tissue's macromolecular content. METHOD: 18 macroscopically intact cartilage-bone samples were obtained from the central lateral femoral condyles of 18 patients undergoing total knee replacement. Serial T1rho mapping was performed on a clinical 3.0-T MRI system using a modified prostate coil. Spin-lock multiple gradient-echo sequences prior to, during and after standardized indentation loading (displacement controlled, strain 20%) were used to obtain seven serial T1rho maps: unloaded (delta0), quasi statically loaded (indentation1-indentation3) and under subsequent relaxation (relaxation1-relaxation3). After manual segmentation, zonal and regional regions of-interest were defined. ROI-specific relative changes were calculated and statistically assessed using paired t-tests. Histological (Mankin classification) and biomechanical (unconfined compression) evaluations served as references. RESULTS: All samples were histologically and biomechanically grossly intact (Mankin sum: 1.8 +/- 1.2; Young's Modulus: 0.7 +/- 0.4 MPa). Upon loading, T1rho consistently increased throughout the entire sample thickness, primarily subpistonally (indentation1 [M +/- SD]: 9.5 +/- 7.8% [sub-pistonal area, SPA] vs 4.2 +/- 5.8% [peri-pistonal area, PPA]; P < 0.001). T1rho further increased with ongoing loading (indentation3: 14.1 +/- 8.1 [SPA] vs 7.7 +/- 5.9% [PPA]; P < 0.001). Even upon unloading (i.e., relaxation), T1rho persistently increased in time. CONCLUSION: Serial T1rho-mapping reveals distinct and complex zonal and regional changes in articular cartilage as a function of loading and unloading. Thereby, longitudinal adaptive processes in hyaline cartilage become evident, which may be used for the tissue's non-invasive functional characterization by T1rho. PMID- 29175372 TI - NAD-biosynthetic enzyme NMNAT1 reduces early behavioral impairment in the htau mouse model of tauopathy. AB - NAD metabolism and the NAD biosynthetic enzymes nicotinamide nucleotide adenylyltransferases (NMNATs) are thought to play a key neuroprotective role in tauopathies, including Alzheimer's disease. Here, we investigated whether modulating the expression of the NMNAT nuclear isoform NMNAT1, which is important for neuronal maintenance, influences the development of behavioral and neuropathological abnormalities in htau mice, which express non-mutant human tau isoforms and represent a model of tauopathy relevant to Alzheimer's disease. Prior to the development of cognitive symptoms, htau mice exhibit tau hyperphosphorylation associated with a selective deficit in food burrowing, a behavior reminiscent to activities of daily living which are impaired early in Alzheimer's disease. We crossed htau mice with Nmnat1 transgenic and knockout mice and tested the resulting offspring until the age of 6 months. We show that overexpression of NMNAT1 ameliorates the early deficit in food burrowing characteristic of htau mice. At 6 months of age, htau mice did not show neurodegenerative changes in both the cortex and hippocampus, and these were not induced by downregulating NMNAT1 levels. Modulating NMNAT1 levels produced a corresponding effect on NMNAT enzymatic activity but did not alter NAD levels in htau mice. Although changes in local NAD levels and subsequent modulation of NAD dependent enzymes cannot be ruled out, this suggests that the effects seen on behavior may be due to changes in tau phosphorylation. Our results suggest that increasing NMNAT1 levels can slow the progression of symptoms and neuropathological features of tauopathy, but the underlying mechanisms remain to be established. PMID- 29175374 TI - Social capital and preventive care use among the elderly under Taiwan's National Health Insurance. AB - OBJECTIVE: The National Health Insurance (NHI) system in Taiwan provides free annual preventive care services and other disease-specific preventive care services under low copayments to people aged 65 and older, yet their utilization rates remain low ever since implementation. This study investigates whether social capital is associated with preventive care use among people aged 65 and older. METHOD: Using the 2009 National Health Interview Study, this study measures social capital by the elderly's social network and social participation, and employs the logistic regressions to estimate the association between social capital and the odds of using a variety of preventive care services. RESULTS: The results show that social capital in terms of social network and social participation is significantly associated with the use of NHI general preventive care services. For disease-specific preventive care, it is social participation, rather than social network, that is related to the utilization rate. CONCLUSION: The associations between social capital and different types of preventive care use found in our study could be considered as an important factor when making policies to promote the utilization of preventive care. PMID- 29175375 TI - Posttraumatic growth among people with serious mental illness, psychosis and posttraumatic stress symptoms. AB - Recent research has shown high rates of exposure to trauma among people with serious mental illness (SMI). In addition, studies suggest that psychosis and mental illness-related experiences can be extremely traumatic. While some individuals develop posttraumatic symptomatology related to these experiences, some appear to experience posttraumatic growth (PTG). Little is known, however, about PTG as a possible outcome among people who experienced psychosis as well as posttraumatic stress symptoms (PTSS). For further understanding of the relationship between PTSS and PTG among people with SMI who experienced psychosis, 121 participants were recruited from community mental health rehabilitation centers and administered trauma and psychiatric questionnaires. Results revealed that while high levels of traumatic exposure were common, most participants experienced some level of PTG which was contingent upon meaning making and coping self-efficacy. In addition, posttraumatic avoidance symptoms were found to be a major obstacle to PTG. The range of effect sizes for significant results ranged from eta2=0.037 to eta2=0.144. These findings provide preliminary evidence for the potential role of meaning making and coping self efficacy as mediators of PTG in clinical, highly traumatized populations of people with SMI and psychosis. Implications of these findings for future research and clinical practice are discussed. PMID- 29175376 TI - Control of nuclear beta-dystroglycan content is crucial for the maintenance of nuclear envelope integrity and function. AB - beta-Dystroglycan (beta-DG) is a plasma membrane protein that has ability to target to the nuclear envelope (NE) to maintain nuclear architecture. Nevertheless, mechanisms controlling beta-DG nuclear localization and the physiological consequences of a failure of trafficking are largely unknown. We show that beta-DG has a nuclear export pathway in myoblasts that depends on the recognition of a nuclear export signal located in its transmembrane domain, by CRM1. Remarkably, NES mutations forced beta-DG nuclear accumulation resulting in mislocalization and decreased levels of emerin and lamin B1 and disruption of various nuclear processes in which emerin (centrosome-nucleus linkage and beta catenin transcriptional activity) and lamin B1 (cell cycle progression and nucleoli structure) are critically involved. In addition to nuclear export, the lifespan of nuclear beta-DG is restricted by its nuclear proteasomal degradation. Collectively our data show that control of nuclear beta-DG content by the combination of CRM1 nuclear export and nuclear proteasome pathways is physiologically relevant to preserve proper NE structure and activity. PMID- 29175377 TI - Soft drug-resistant ovarian cancer cells migrate via two distinct mechanisms utilizing myosin II-based contractility. AB - The failure of chemotherapeutic drugs in treatment of various cancers is attributed to the acquisition of drug resistance. However, the migration mechanisms of drug-resistant cancer cells remain incompletely understood. Here we address this question from a biophysical perspective by mapping the phenotypic alterations in ovarian cancer cells (OCCs) resistant to cisplatin and paclitaxel. We show that cisplatin-resistant (CisR), paclitaxel-resistant (PacR) and dual drug-resistant (i.e., resistant to both drugs) OCCs are more contractile and softer than drug-sensitive cells. Protease inhibition suppresses invasion of CisR cells but not of PacR cells, indicative of a protease-dependent mode of migration in CisR cells and a protease-independent mode of migration in PacR. Despite these differences, actomyosin contractility, mediated by the RhoA-ROCK2-Myosin II signaling pathway, regulates both modes of migration. Confined migration experiments establish the role of myosin IIA and IIB in mediating nuclear translocation and regulation of proteolytic activity. Collectively, our results highlight the importance of myosin II as a potential therapeutic target for treatment of drug-resistant ovarian cancer cells. PMID- 29175378 TI - Increased activity of both CDK1 and CDK2 is necessary for the combinatorial activity of WEE1 inhibition and cytarabine. AB - Inhibition of WEE1 is emerging as a promising chemosensitization strategy in many cancers including acute leukemia. Our lab and others have demonstrated that a small-molecule inhibitor of WEE1, AZD1775, sensitizes acute leukemia cells to cytarabine; however, a mechanism of combinatorial activity has remained elusive. Thus, we sought to determine the relative contribution of WEE1 targets CDK1 and CDK2 to the combinatorial activity of AZD1775 and cytarabine. To accomplish this, we expressed "WEE1 resistant" CDK1 (CDK1-AF) and CDK2 (CDK2-AF) constructs in a T ALL cell line. Expression of CDK1/2-AF together, but neither alone, enhanced the anti-proliferative effects, DNA damage and apoptosis induced by cytarabine. Furthermore, pharmacologic inhibition of CDK1 alone or CDK1 and CDK2 together reduced the combinatorial activity of AZD1775 and cytarabine. Thus, increased activity of both CDK1 and CDK2 in response to WEE1 inhibition is necessary for the combinatorial activity of AZD1775 and cytarabine. This suggests the role of WEE1 in cells with accumulated DNA damage extends beyond regulation of CDK1 and the G2/M checkpoint and highlights the importance of WEE1 in mediating progression through the cell cycle. PMID- 29175380 TI - Anodal transcranial direct current stimulation over left inferior frontal gyrus enhances sentence comprehension. AB - We tested the possibility of enhancing natural language comprehension through the application of anodal tDCS (a-tDCS) over the left inferior frontal gyrus, a key region for verbal short-term memory and language comprehension. We designed a between subjects sham- and task-controlled study. During tDCS stimulation, participants performed a sentence to picture matching task in which targets were sentences with different load on short-term memory. Regardless of load on short term memory, the Anodal group performed significantly better than the Sham group, thus providing evidence that a-tDCS over LIFG enhances natural language comprehension. To our knowledge, we apply for the first time tDCS to boost sentence comprehension. This result is of special interest also from a clinical perspective: applying a-tDCS in patients manifesting problems at the sentence level due to brain damage could enhance the effects of behavioral rehabilitation procedures aimed to improve language comprehension. PMID- 29175379 TI - Ex-vivo sensitivity profiling to guide clinical decision making in acute myeloid leukemia: A pilot study. AB - A precision medicine approach is appealing for use in AML due to ease of access to tumor samples and the significant variability in the patients' response to treatment. Attempts to establish a precision medicine platform for AML, however, have been unsuccessful, at least in part due to the use of small compound panels and having relatively slow turn over rates, which restricts the scope of treatment and delays its onset. For this pilot study, we evaluated a cohort of 12 patients with refractory AML using an ex vivo drug sensitivity testing (DST) platform. Purified AML blasts were screened with a panel of 215 FDA-approved compounds and treatment response was evaluated after 72h of exposure. Drug sensitivity scoring was reported to the treating physician, and patients were then treated with either DST- or non-DST guided therapy. We observed survival benefit of DST-guided therapy as compared to the survival of patients treated according to physician recommendation. Three out of four DST-treated patients displayed treatment response, while all of the non-DST-guided patients progressed during treatment. DST rapidly and effectively provides personalized treatment recommendations for patients with refractory AML. PMID- 29175381 TI - 20-Hydroxyecdysone promotes release of GBP-binding protein from oenocytoids to suppress hemocytic encapsulation. AB - Growth-blocking peptide (GBP) is an insect cytokine that stimulates plasmatocyte adhesion, thereby playing a critical role in encapsulation reaction. It has been previously demonstrated that GBP-binding protein (GBPB) is released upon oenocytoid lysis in response to GBP and is responsible for subsequent clearance of GBP from hemolymph. However, current knowledge about GBPB is limited and the mechanism by which insects increase GBPB levels to inactivate GBP remains largely unexplored. Here, we have identified one GBP precursor (HaGBP precursor) gene and two GBPB (namely HaGBPB1 and HaGBPB2) genes from the cotton bollworm, Helicoverpa armigera. The HaGBP precursor was found to be predominantly expressed in fat body, whereas HaGBPB1 and HaGBPB2 were mainly expressed in hemocytes. Immunological analyses indicated that both HaGBPB1 and HaGBPB2 are released from hemocytes into the plasma during the wandering stage. Additionally, 20 hydroxyecdysone (20E) treatment or bead challenge could promote the release of HaGBPB1 and HaGBPB2 at least partly from oenocytoids into the plasma. Furthermore, we demonstrate that the N-terminus of HaGBPB1 is responsible for binding to HaGBP and suppresses HaGBP-induced plasmatocyte spreading and encapsulation. Overall, this study helps to enrich our understanding of the molecular mechanism underlying 20E mediated regulation of plasmatocyte adhesion and encapsulation via GBP-GBPB interaction. PMID- 29175382 TI - The Influence of Social Threat on Pain, Aggression, and Empathy in Women. AB - : Only one published study has investigated the effect of a threatening social context on the perception and expression of pain, showing that social threat leads to increased pain reports but reduced nonverbal pain expression. The current study aimed to replicate and extend these findings to further explore the effects of a threatening social context. Healthy, female participants (N = 71) received 10 electrocutaneous stimuli delivered by a confederate. They were led to believe that the confederate was requested to administer 10 painful stimuli (control group) or that the confederate deliberately chose to deliver 10 painful stimuli when given the choice to deliver between 1 to 10 painful stimuli (social threat group). Self-reported pain intensity, unpleasantness, threat value of pain, and painful facial expression were assessed. Additionally, empathy and aggression toward the confederate were investigated. Social threat did not affect painful facial expression or self-reported pain intensity, but led to increased aggression toward the confederate. Moreover, perceived social threat predicted the threat value of pain and reduced empathy toward the confederate. We were not able to replicate the previously reported dissociation between pain reports and pain expression as a result of social threat. However, social threat was associated with an increased threat value of pain, increased aggression, and reduced empathy. PERSPECTIVE: A threatening social context affects how threatening pain is perceived and has interpersonal consequences such as increased aggression and reduced empathy, thereby creating a double burden on the individual suffering from pain. PMID- 29175383 TI - An efficient algorithm for dynamic MRI using low-rank and total variation regularizations. AB - In this paper, we propose an efficient algorithm for dynamic magnetic resonance (MR) image reconstruction. With the total variation (TV) and the nuclear norm (NN) regularization, the TVNNR model can utilize both spatial and temporal redundancy in dynamic MR images. Such prior knowledge can help model dynamic MRI data significantly better than a low-rank or a sparse model alone. However, it is very challenging to efficiently minimize the energy function due to the non smoothness and non-separability of both TV and NN terms. To address this issue, we propose an efficient algorithm by solving a primal-dual form of the original problem. We theoretically prove that the proposed algorithm achieves a convergence rate of O(1/N) for N iterations. In comparison with state-of-the-art methods, extensive experiments on single-coil and multi-coil dynamic MR data demonstrate the superior performance of the proposed method in terms of both reconstruction accuracy and time complexity. PMID- 29175384 TI - Neuron-specific enolase and S-100b in prolonged targeted temperature management after cardiac arrest: A randomised study. AB - BACKGROUND: We aimed to investigate the impact of prolonged targeted temperature management (TTM) in cardiac arrest patients on release of serum levels of NSE and S-100b and their prognostic performances. METHODS: This is a substudy of the Targeted Temperature Management for 24 vs 48h trial. NSE and S-100b levels were analysed retrospectively in serum samples collected upon admission, at 24, 48, and 72h after reaching the target temperature of 33+/-1 degrees C. The primary outcome was biomarker serum concentrations and secondary outcome was the cerebral performance category score after 6 months. RESULTS: 115 patients from two centres were analysed. NSE and S-100b levels did not differ between TTM groups at any single time-point. Poor outcome patients had higher biomarker levels at 24, 48, and 72h: NSE: 9.73 (7.2; 10.9) versus 20.40 (12.7; 27.2), 8.86 (6.6; 9.6) versus 17.47 (11.1; 37.3) and 6.23 (5.3; 8.5) versus 31.05 (12.8; 52.5) respectively and S-100b: 0.09 (0.07; 0.11) versus 0.23 (0.19; 0.39), 0.08 (0.07; 0.09) versus 0.18 (0.15; 0.33) and 0.07 (0.06; 0.08) versus 0.13 (0.09; 0.23). The daily changes in NSE from admission to Day 2 after the cardiac arrest (CA) were also related to the outcome (p=0.003 and p=0.02). The best prediction of outcome was found at 72h for NSE and at 24h as well as 48h for S100b. CONCLUSIONS: No clinically relevant differences were found in the levels of NSE or S-100b between standard and prolonged TTM. Prognostic reliability of NSE and S-100b was unaltered by prolonged TTM. PMID- 29175385 TI - Timing of coronary angiography in survivors of out-of-hospital cardiac arrest without obvious extracardiac causes. AB - BACKGROUND: Indications and timing of coronary angiography in patients surviving out-of-hospital cardiac arrest (OHCA) remain controversial. The aim of the present study was to assess the impact of an early invasive strategy in patients presenting with an OHCA and no obvious extracardiac cause. METHODS: Between January 1st 2009 and December 31st 2014 a total 612 survivors of OHCA were admitted to our institution. Patients with no obvious extracardiac cause (n=507) were stratified into two groups: patients that underwent cardiac catheterization <=3h (early invasive; n=291) and patients not undergoing cardiac catheterization within 3h (non-early invasive; n=216). Primary endpoint was all-cause mortality at 30days. RESULTS: All-cause 30-day mortality was 28.9% in the early invasive group vs. 36.6% in the non-early invasive group (log-rank p=0.071). After propensity analyses, an early invasive strategy, as compared to a non-early strategy, was not associated with 30-day mortality (adjusted Hazard ratio [HR] 0.69; 95% CI 0.35-1.37; p=0.029). Cox multivariable regression analyses demonstrated age (HR 1.04/year; 95% CI 1.02-1.07) and presentation with cardiogenic shock (HR 5.1; 95% CI 1.8-14.0) to be the sole independent predictors of 30-day mortality. CONCLUSIONS: In this retrospective study, early coronary angiography (<3h), as compared to a non-early invasive strategy, was not associated with reduced 30-day mortality in patients hospitalized after OHCA, irrespective of the presence of ST segment elevation or cardiogenic shock at presentation. PMID- 29175386 TI - Impact of Clinicopathologic Features on the Efficacy of PD-1/PD-L1 Inhibitors in Patients With Previously Treated Non-small-cell Lung Cancer. AB - BACKGROUND: The current study aimed to comprehensively investigate the impact of various clinicopathologic features on the efficacy of programmed cell death-1 (PD 1) and ligand (PD-L1) inhibitors in patients with previously treated non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Randomized controlled trials that compared PD-1/PD-L1-inhibitor monotherapy with chemotherapy or placebo in patients with previously treated NSCLC were included. RESULTS: Five trials were included (n = 3025). For all studies, PD-1/PD-L1 inhibitors significantly prolonged overall survival (OS) (hazard ratio [HR], 0.70; P < .001) and progression-free survival (PFS) versus chemotherapy (HR, 0.86; P = .020). Subgroup analysis showed that anti-PD-1/PD-L1 monotherapy could markedly improve OS in elderly patients (HR, 0.69; P < .001), female patients (HR, 0.70; P < .001), never-smoking patients (HR, 0.73; P = .001), and patients with a histology of squamous cell carcinoma (HR, 0.67; P < .001), but not PFS in the elderly and female patient groups. Notably, PD-1/PD-L1 inhibitors cannot prolong both OS (HR, 0.76; P = .390) and PFS (HR, 0.74; P = .210) in patients with central nervous system (CNS) metastasis, whereas patients without CNS metastasis could benefit from anti-PD-1/PD-L1 monotherapy on OS (HR, 0.71; P < .001). CONCLUSION: PD-1/PD L1-inhibitor monotherapy could significantly prolong both OS and PFS in patients with previously treated NSCLC. Subgroup analyses showed that most patients including elderly, females, never-smokers, and patients with squamous cell carcinomas do benefit. However, whether patients with CNS metastasis could benefit from anti-PD-1/PD-L1 monotherapy requires further validation. PMID- 29175387 TI - Baicalein inhibits cervical cancer progression via downregulating long noncoding RNA BDLNR and its downstream PI3K/Akt pathway. AB - Baicalein, an active flavonoid extracted from the root of Scutellaria baicalensis Georgi, has fascinating anti-cancer effects on many cancers. Our previous study also found that baicalein inhibited cervical cancer cell proliferation and migration, and induced cervical cancer cell apoptosis and cell cycle arrest. However, the molecular mechanisms underlying the anti-cancer effects of baicalein are largely unknown. In this study, we identified a novel long noncoding RNA (lncRNA), which is downregulated by baicalein in a dose- and time-dependent manner in cervical cancer. We named this lncRNA as baicalein down-regulated long noncoding RNA (BDLNR). Gain-of- and loss-of-function assays showed that BDLNR was required for baicalein-induced cell proliferation inhibition, cell death induction, migration inhibition, and in vivo tumor growth inhibition of cervical cancer. Mechanistically, BDLNR physically bound to YBX1, recruited YBX1 to PIK3CA promoter, activated PIK3CA expression and PI3K/Akt pathway. Furthermore, BDLNR was upregulated in cervical cancer and associated with poor prognosis of cervical cancer patients. Collectively, our data demonstrated that BDLNR mediated the anti cancer effects of baicalein in cervical cancer via activating PI3K/Akt pathway, and implied that BDLNR would be potential therapeutic target for enhancing the anti-cancer effects of baicalein in cervical cancer. PMID- 29175388 TI - Functional FRIGIDA allele enhances drought tolerance by regulating the P5CS1 pathway in Arabidopsis thaliana. AB - Flowering at the right time is important for the reproductive success of plants and their response to environmental stress. In Arabidopsis, a major determinant of natural variation in flowering time is FRIGIDA (FRI). In the present study, we show that overexpression of the functional FRIGIDA gene in wild-type Col background (ColFRI) positively enhances the drought tolerance by activating P5CS1 expression and promoting proline accumulation during water stress. Furthermore, no significant changes in FRI gene and protein expression levels were observed with drought treatment, whereas P5CS1 protein expression significantly increased. In contrast, vernalization treatment efficiently reduced P5CS1 expression levels and resulted in a decrease in drought tolerance in the ColFRI plants. The flc mutants with a functional FRI background also relieved FRI-mediated activation of P5CS1 during drought tolerance. Taken together, our findings reveal the novel function of FRI in enhancing drought resistance through its downstream P5CS1 pathway during water-deficit stress, which is dependent on its target, the FLC gene. PMID- 29175389 TI - Repetitive restraint stress changes spleen immune cell subsets through glucocorticoid receptor or beta-adrenergic receptor in a stage dependent manner. AB - Immune system is sensitive to stress. Spleen is the largest peripheral immune organ innervated with sympathetic nerves and controlled by adrenomedullary system in the body. However, the alterations and mechanism of spleen immune cell subsets caused by repetitive restraint stress (RRS) is poorly understood. In this study, we found that RRS reduced spleen index in mice, and induced an expansion of white pulp and involution of the red pulp. Meanwhile, the percentage of CD3+CD8+ T lymphocytes, CD11b+F4/80+ macrophages, CD11b+Ly-6G-Ly-6Chi monocytic myeloid derived suppressor cells (mMDSCs) and CD11b+Ly-6G+Ly-6Cint granulocytic myeloid derived suppressor cells (gMDSCs) in spleen were significantly changed by RRS. Mechanistically, we found that the expression of norepinephrine (NE) and beta adrenergic receptor (beta-AR) in spleen were up-regulated after 21 days of RRS, but not 7 days. The expression of corticosterone (CORT) and glucocorticoid receptor (GR) in spleen were up-regulated after 7 days of RRS but were lower after 21 days of RRS, even though they were still higher than that in mice without stress. By treating the stressed mice with RU486 (antagonist of GR) or propranolol (antagonist of beta-AR), we demonstrated that GR was responsible for the changes of spleen induced by 7 days of RRS and beta-AR was for 21 days of RRS. Our data suggest that RRS changes spleen immune cell subsets through GR or beta-AR in a stage dependent manner.

AB - To repair bone defects, we evaluate the in-vitro and in-vivo osteogenic activities of a novel tissue-engineered bone (TEB) by elaborately combining biomimetic calcium phosphate (BioCaP) granules with internally-incorporated simvastatin (SIM) and human adipose-derived stem cells (hASCs). First, we constructed BioCaP with SIM internally incorporated (SIM-BioCaP). Then we characterized the morphology and chemical composition of SIM-BioCaP. The release kinetics of SIM was monitored in vitro spectroscopically. Thereafter, we explored the in-vitro cellular responses of hASCs to SIM-BioCaP by performing scanning electron microscopy observation, proliferation assay, alkaline phosphatase (ALP) activity assay, alizarin red staining and real-time PCR. Finally, we investigated the in-vivo osteogenic activities of the novel TEB in a subcutaneous bone induction model in nude mice. We found that SIM was successfully incorporated internally in BioCaP and showed a slow release manner without significantly affecting the attachment and proliferation of hASCs. The released SIM from BioCaP could significantly enhance the proliferation, ALP activities, mineralized nodules formation and osteogenic genes of hASCs. The in-vivo tests showed this TEB could induce new bone formation while the other groups could not. Taken together, the present data show that this novel TEB represented a very promising construct to treat critical-volume bone defects.

AB - The innate immune system governed by toll-like receptors (TLRs) provides the first line of defense against pathogens. Surface-localized TLR1 and TLR6 are known to detect parasite components. TLR encoding genes were shown to display signatures of recent positive selection in Europeans and might be involved in local adaptation at immune-related genes. To verify the influence of Brazilian population admixture on the distribution of polymorphisms in TLRs, we analyzed the genotype frequencies of 24 polymorphisms distributed across five TLR genes in a Southeastern Brazilian population where autochthonous cases of malaria occur in small foci of transmission. The estimation of ancestry showed mainly European ancestry (63%) followed by African ancestry (22%). Mean proportions of European ancestry differed significantly between the genotypes of the TLR1 (I602S) gene and in the TLR6 (P249S) gene. The chance of having the G allele in TLR1 gene increases as European ancestry increases as well as the chance of having the T allele in the TLR6 gene. The 602S allele is related to a ''hypo-responsiveness'' possibly explaining the high prevalence of asymptomatic malaria cases in areas of Southeastern Brazil. Our results underline the necessity to include informative ancestry markers in genetic association studies in order to avoid biased results. PMID- 29175393 TI - Total body and arm bioimpedance in patients with Alzheimer's disease. AB - PURPOSE OF THE RESEARCH: To analyse body composition of patients with Alzheimer's disease (AD) using total body and localized specific bioelectrical impedance vector analysis (specific BIVA). METHOD: 127 patients (50 men, 78.2+/-6.3years; 77 women, 81.4+/-6.8years) with mild to moderate stages of AD were selected from the Geriatric Division, SS. Trinita Hospital of Cagliari (Italy). A sample of 135 healthy age-matched individuals (74 men, 77.4+/-5.3years; 61 women, 80.4+/ 5.5years) was chosen as control group. Anthropometric measurements were taken and body mass index (BMI) was calculated. Bioelectrical measurements were taken on the right side of the body for both the whole-body and the arm, using a BIA 101 analyser (Akern). Body composition was assessed by means of specific bioelectrical impedance vector analysis (specific BIVA). The comparison between patients and the control group was performed by two-factor analysis of variance and Hotelling's T2 test. RESULTS: In comparison with the control group, patients with AD showed similar anthropometric characteristics, including BMI, but lower lean tissue mass and higher percent fat mass, as indicated by the lower phase angles and longer specific vectors. The same body composition peculiarities were detected considering only the right arm. CONCLUSION: Patients with AD show characteristics - lower lean mass/higher percent fat mass - that can be detected by both total body and localized bioimpedance approaches. This suggests the possibility of a new, quicker and simpler procedure for body composition assessment. PMID- 29175391 TI - Integrated functional and mass spectrometry-based flow cytometric phenotyping to describe the immune microenvironment in acute myeloid leukemia. AB - A hallmark of the development of cancer is its ability to avoid detection and elimination by the immune system. There are many identified mechanisms of this immune evasion that can be measured both phenotypically and functionally. Functional studies directly show the ability of the tumor microenvironment to suppress immune responses, typically measured as lymphocyte proliferation, cytokine production or killing ability. While a direct measurement of function is ideal, these assays require ex vivo activation which may not accurately mimic in vivo conditions. Phenotypic assays can directly measure the distribution and activation of immune cell types rapidly after isolation, preserving the conditions present in the patient. While conventional flow cytometry is a rapid and well established assay, it currently allows for measurement of only 12-14 parameters. Mass spectrometry-based flow cytometry, or CyTOF, offers the ability to measure 3-fold more parameters than conventional optical-based modalities providing an advantage in depth of analysis that can be crucial for precious human samples. The goal of this report is to describe the system our group has developed to measure both the phenotype and function of immune cells in the bone marrow of patients with acute myeloid leukemia. We hope to explain our system in the context of previous studies aimed at measuring immune status in tumors and to inform the reader as to some experimental approaches our group has found useful in developing the basic data required to rationally pursue immune-based therapies for patients with cancer.

AB - The phytoremediation potential of 14 different plant species belonging to C3 and C4 carbon fixation pathway for soils spiked with polycyclic aromatic hydrocarbons (PAHs) such as benzo[a]pyrene (B[a]P) and pyrene (PYR) was investigated. A glasshouse experiment was conducted to measure the changes in morphological, physiological, biochemical parameters and the bioaccumulation and biodegradation ability of the plants in soils spiked with 48 and 194 mg kg-1 of B[a]P and PYR, respectively. The per cent removal efficacy of B[a]P and PYR by the tested plant species over a period of 50 days was from 6 to 26% and 14 to 40% respectively. The maximum removal of both B[a]P and PYR was observed in Sudan grass (C4), vetiver (C4), maize (C4), and sunflower (C3). In terms of accumulation in root and shoot, the concentration of PYR was higher in both C3 and C4 plant species when compared to B[a]P. Overall the results indicated that C4 plants were more efficient than their C3 counterparts in terms of morphological, physiological, biochemical and degradation ability of PAHs.

AB - Albendazole is a broad-spectrum anthelmintic drug effective against gastrointestinal parasites in humans and animals. Despite the fact that it has been detected in environment (water, sediment and soil), there is no information on its fate in the environment. So, in order to understand the sorption process of albendazole in environment, the sorption mechanism and kinetic properties were investigated through sorption equilibrium and sorption rate experiments. For that purpose, batch sorption of albendazole on five sediment samples and five soil samples from Croatia's region with different physico-chemical properties was investigated. Except physico-chemical properties of used environmental solid samples, the effects of various parameters such as contact time, initial concentration, ionic strength and pH on the albendazole sorption were studied. The Kd parameter from linear sorption model was determined by linear regression analysis, while the Freundlich and Langmuir sorption models were applied to describe the equilibrium isotherms. The estimated Kd values varied from 29.438 to 104.43 mLg-1 at 0.01 M CaCl2 and for natural pH value of albendazole solution (pH 6.6). Experimental data showed that the best agreement was obtained with the linear model (R2 > 0.99), while the rate of albendazole sorption is the best described with the kinetic model of pseudo-second-order. Obtained results point to a medium or even strong sorption of albendazole for soil or sediment particles, which is particularly dependent on the proportion of organic matter, pH, copper and zinc in them. PMID- 29175396 TI - Effects of triclosan (TCS) on hormonal balance and genes of hypothalamus pituitary- gonad axis of juvenile male Yellow River carp (Cyprinus carpio). AB - Triclosan (TCS) is a broad spectrum antimicrobial agent which has been widely dispersed and determinated in the aquatic environment. However, the effects of TCS on reproductive endocrine in male fish are poorly understood. In this study, male Yellow River carp (Cyprinus carpio) were exposed to 0, 1/5, 1/10 and 1/20 LC50 (96 h LC50 of TCS to carp) TCS under semi-static conditions for 42 d. Vitellogenin (Vtg), 17beta-estradiol (E2), testosterone(T), gonadotropin (GtH), and gonadotropin-releasing hormone (GnRH) levels were measured by enzyme-linked immunosorbent assay (ELISA). Meanwhile, we also examined the mRNA expressions of aromatase, GtHs-beta, GnRH, estrogen receptor (Er), and androgen receptor (Ar) by quantitative Real-time Polymerase Chain Reaction (qRT-PCR). TCS induced Vtg levels of hepatopancreas, E2 levels of serum, and inhibited Ar and Er mRNA levels, suggesting that the induction of Vtg production by TCS was indirectly caused by non-Er pathways. TCS-induced Vtg levels by interfering with the reproductive axis at plenty of latent loci of male carps: (a) TCS exposure increased the aromatase mRNA expression of hypothalamus and gonad aromatase, consequently increasing serum concentrations of E2 to induce Vtg in hepatopancreas; (b) TCS treatment changed GtH-beta and GnRH mRNA expression and secretion, causing the disturbance of reproductive endocrine; (c) TCS exposure decreased Ar mRNA levels, indicating potential Ar-mediated antiandrogen action. These mechanisms showed that TCS may induce Vtg production in male carp by non-Er mediated pathways. PMID- 29175397 TI - Effect and mechanism analysis of MnO2 on permeable reactive barrier (PRB) system for the removal of tetracycline. AB - Effect of manganese dioxide (MnO2) on tetracycline (TC) removal/degradation in zero-valent iron (ZVI) based permeable reactive barrier (PRB) system was investigated. To analyze the role of MnO2, three different PRB columns packed with ZVI, ZVI and a layer of MnO2, and MnO2 were set up to investigate the removal effect and reaction mechanism of ZVI coupling with MnO2 on TC removal, respectively. The results show that the removal efficiencies of three PRB columns are 65%, 85%, and 50%, respectively. MnO2 could accelerate the transformation of Fe2+ into Fe3+ and combine with Fe3+ to degrade TC in different reaction sites in the ZVI-MnO2 PRB system. Hydroxyl radicals (.OH) were produced in this process, which contributed to about 58.3% for the TC degradation. The UV-Vis spectrum demonstrated that A ring of TC was the main reaction site for interaction with Fe3+ and the BCD rings were crucial for interactions with MnO2. On the basis of intermediates identified by LC-ESI-MS, the ring structure of TC was opened, and low-molecular-weight compounds were produced in ZVI-MnO2 PRB system. PMID- 29175398 TI - Toxic effects and mechanism of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) on Lemna minor. AB - To investigate the toxic effect and mechanism of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) in aquatic plants, in vivo and in vitro exposure to BDE-47 were conducted. After 14-d exposure to 5-20 MUg/L BDE-47, the growth of Lemna minor plants was significantly suppressed, and the chlorophyll and soluble protein contents in fronds markedly decreased. Accordingly, the photosynthetic efficiency (Fv/Fm, PI) decreased. When the thylakoid membranes isolated from healthy fronds was exposed to 5-20 mg/L BDE-47 directly in vitro for 1 h, the photosynthetic efficiency also decreased significantly. In both the in vitro (5-20 MUg/L) and in vivo (5-20 mg/L) experiments, BDE-47 led to an increased plasma membrane permeability. Hence, we concluded that BDE-47 had a direct toxicity to photosynthetic membranes and plasma membranes. However, direct effects on the activities of peroxidase (POD), malate dehydrogenase (MDH) and nitroreductase (NR) were not observed by adding 5-20 mg/L BDE-47 into crude enzyme extracts. The malondialdehyde (MDA) and superoxide anion radical (O2-) contents in the BDE-47 treated fronds were higher than those in the control fronds, suggesting that L. minor can not effectively relieve reactive oxygen species (ROS). The data above indicates that BDE-47 is toxic to L. minor through acting directly on biomembranes, which induces the production of ROS and thus causes remarkable oxidative damage to cells.

AB - A series of laboratory experiments were conducted, in which waste furniture polyurethane foam samples containing tris (1-chloro-2-propyl) phosphate (TCIPP) were contacted with a range of leaching fluids, formulated to simulate the composition of landfill leachate. Leaching was examined under a number of different scenarios, such as: dissolved humic matter concentration, pH, and temperature, as well as the effect of agitation, and waste:leaching fluid contact duration. In addition to single batch (no replenishment of leaching fluid), serial batch (draining of leachate and replenishment with fresh leaching fluid at various time intervals) experiments were conducted. Leaching of TCIPP from PUF appears to be a first order process. Concentrations of TCIPP in leachate generated by the experiments in this study ranged from 13 mg L-1 to 130 mg L-1. In serial batch leaching experiments, >95% of TCIPP was depleted from PUF after 168 h total contact with leaching fluid. Our experiments indicate leaching is potentially a very significant pathway of TCIPP emissions to the environment. PMID- 29175400 TI - Revitalisation of metal-contaminated, EDTA-washed soil by addition of unpolluted soil, compost and biochar: Effects on soil enzyme activity, microbial community composition and abundance. AB - Soil remediation mitigates hazards from contaminants but could deprive soils of initial biota and enzymes. Historically contaminated acidic soil from Arnoldstein (Austria) and calcareous soil from Meza (Slovenia) were washed with 30 and 100 mmol kg-1 ethylenediaminetetraacetate (EDTA) to remove 78 and 60% of Pb as a main pollutant. Remediation of the Arnoldstein soil decreased urease activity and increased beta-glucosidase activity, measured in a 15-week experiment. The dehydrogenase activity and microbial gene abundances were not significantly impeded compared to the original soil. Conversely, the use of a high dose of EDTA in the Meza soil, necessary for effective remediation of calcareous soils, resulted in pronouncedly decreased enzyme activities (3.2 times on average) and repressed fungal ITS and increased bacterial 16S rRNA gene abundance. Remediation shifted the microbial community composition in both soils. For revitalisation, the remediated soils were amended with compost, inocula of un-contaminated soil and (Arnoldstein soil) biochar enriched with soil extract. Amendments inconsistently affected the Arnoldstein soil: compost increased the dehydrogenase activity and altered the microbial community composition, biochar enhanced the beta-glucosidase activity, and all amendments decreased the microbial abundance (1.6 times on average). In contrast, amendments efficiently revitalised the remediated Meza soil; compost and soil inoculum returned the enzyme activities back to the baseline in the original soil, increased the fungal abundance above that in the original soil and restored the microbial community composition. PMID- 29175401 TI - Mesoporous nanoplate multi-directional assembled Bi2WO6 for high efficient photocatalytic oxidation of NO. AB - Herein, a mesoporous nanoplate multi-directional assembled Bi2WO6 architecture was successfully prepared and applied for the photocatalytic removal of NOx pollutants at low concentrations under visible light and simulated solar light irradiation. Bi2WO6-180-C synthesized at a hydrothermal temperature of 180 degrees C with calcination exhibited an excellent conversion efficiency in the photocatalytic oxidation of gaseous NO. The crystallinity, morphology, specific surface area, pore environment, light absorption, and separation of photogenerated electrons and holes were investigated by various techniques; the excellent photocatalytic performance of Bi2WO6-180-C was attributed to its special hierarchical mesoporous structure with an appropriate pore size and interconnected porous network, which imparted good gas permeability and fast mass transfer of reaction intermediates and final products of NO oxidation. Furthermore, hierarchical mesoporous Bi2WO6 showed excellent photocatalytic durability and reusability. PMID- 29175402 TI - Neurobehavioral assessment of rats exposed to pristine polystyrene nanoplastics upon oral exposure. AB - The increasing use of plastics has raised concerns about pollution of freshwater by these polymeric materials. Knowledge about their potential effects on environmental and public health is limited. Recent publications have suggested that the degradation of plastics will result in the release of nano-sized plastic particles to the environment. Therefore, it is of utmost importance to gain knowledge about whether and how nanoplastics affect living organisms. The present study aimed to analyse potential neurobehavioral effects of polystyrene nanoparticles (PS-NPs) after long-term exposure on rat. Potential effects of PS NPs were investigated using four test dosages (1, 3, 6, and 10 mg PS-NPs/kg of body weight/day) administrated orally with adult Wistar male rats for five weeks. Neurobehavioral tests were chosen to assess a variety of behavioral domains. Particle diameters in test suspensions were determined through dynamic light scattering and showed an average hydrodynamic diameter of approximately 38.92 nm. No statistically significant behavioral effects were observed in all tests performed (p > 0.05). In the elevated plus maze, PS-NPs-exposed rats showed greater number of entries into open arms compared to controls. Also, PS-NPs had no significant influence on body weight of animals. Taking into account the subtle and transient nature of neurobehavioral consequences, however, these results underline the possibility of even pristine plastic nanoparticles to induce behavioral alteration in the rest of the food web, including for marine biota and humans. Indeed even though studied neurobehavioral effects in our study was not statistically significant, the observed subtle effects may be clinically considerable. PMID- 29175403 TI - Measuring and modeling surface sorption dynamics of organophosphate flame retardants on impervious surfaces. AB - Understanding the sorption mechanisms for organophosphate flame retardants (OPFRs) on impervious surfaces is important to improve our knowledge of the fate and transport of OPFRs in indoor environments. The sorption processes of semivolatile organic compounds (SVOCs) on indoor surfaces are heterogeneous (multilayer sorption) or homogeneous (monolayer sorption). In this study, we adopted simplified Langmuir isotherm and Freundlich isotherm in a dynamic sink model to characterize the sorption dynamics of OPFRs on impervious surfaces such as stainless steel and made comparisons between the two models through a series of empty chamber studies. The tests involve two types of stainless steel chambers (53-L small chambers and 44-mL micro chambers) using tris(2-chloroethyl)phosphate (TCEP) and tris(1-chloro-2-propyl)phosphate (TCPP) as target compounds. Our test results show that the dynamic sink model using Freundlich isotherm can better represent the sorption process in the empty small chamber. Micro chamber test results from this study show that the sink model using both simplified Langmuir isotherm and Freundlich isotherm can well fit the measured gas-phase concentrations of OPFRs. We further applied both models and the parameters obtained to predict the gas phase concentrations of OPFRs in a small chamber with an emission source. Comparisons between model predictions and measurements demonstrate the reliability and applicability of the sorption parameters. PMID- 29175404 TI - Geochemical sources, hydrogeochemical behavior, and health risk assessment of fluoride in an endemic fluorosis area, central Iran. AB - The present study is the first attempt to put forward the possible source(s) and health risk assessment of fluoride in Bahabad, central Iran. Fluoride concentrations ranged from 0.22 to 2.35 mg/L and 292-355 mg/kg in the groundwater and soil samples, respectively. Geochemical provenance techniques using major and rare earth elements in soils revealed that local shale is the most probable source rock of fluoride in the area. A two-step chemical fractionation method applied on soil samples demonstrated that residual and water-soluble fractions were the most probable modes of fluoride in soil, whereas exchangeable fraction had a minor role. The coefficient of aqueous migration showed that fluoride in the studied soils behaved as a mobile element. Moreover, the relative mobility indicated that soils played a more important role than rocks in releasing fluoride into groundwater. In groundwater medium, chemical weathering, evaporation, and ion exchange acted as the main geochemical controlling factors of fluoride enrichment. Findings of this study signify that the role of NaCl and NaSO4-type waters should be considered more to recognize susceptible areas to fluoride contamination in groundwater. People in the study area are exposed to high levels of fluoride intake through drinking water, thus making dental fluorosis a major public health concern in the area. Scanning electron microscopy of the dentin's enamel showed morphological modifications (e.g., cracks and fissures) in residents' enamel structures. The results of this study may lead to suitable management strategies to mitigate the endemic fluorosis problem. PMID- 29175405 TI - Arsenic concentrations and speciation in wild birds from an abandoned realgar mine in China. AB - Birds are at a higher level in the food chain; however, the potential bioaccumulation and biotransformation of arsenic (As) in birds in As mines has rarely been studied. In this study, four passerine bird species (tree sparrow [Passer montanus], light-vented bulbul [Pycnonotus sinensis], Garrulax canorus [Leucodioptron canorus], and magpie [Pica pica]) were collected from an abandoned As mine in China. The highest recorded As concentrations were 4.95 mg/kg and 51.65 mg/kg in muscles and feathers, respectively. Detection using high performance liquid chromatography inductively coupled plasma mass spectrometry (HPLC-ICP-MS) revealed six As species, including arsenite (As(III)), arsenate (As(V)), dimethylarsinic acid (DMA), monomethylarsonic acid (MMA), arsenobetaine (AsB) and arsenocholine (AsC), with the former three species as the dominant (>92%) and the latter three as the minor As species (<6.17%). Further analysis of the selected bird samples using the X-ray absorption near edge structure (XANES) technique revealed the existence of As(III)-tris-glutathione (As(III)-GSH), which can be regarded as equivalent to the non-extractable and unidentified As form in the HPLC-ICP-MS data. Both methods revealed similar patterns of As species in the birds from the As mine, with muscles containing mainly inorganic As and DMA and feathers containing mainly inorganic As. The results of this study contribute to the knowledge regarding As accumulation and speciation in terrestrial organisms. PMID- 29175406 TI - Evaluation of carbon isotope fractionation during anaerobic reductive dehalogenation of chlorinated and brominated benzenes. AB - Compound specific stable isotope analysis (CSIA) has been established as a useful tool to evaluate in situ biodegradation. Here, CSIA was used to determine microbial dehalogenation of chloro- and bromobenzenes in microcosms derived from Hackensack River sediments. Gas chromatography-isotope ratio mass spectrometry (GC-IRMS) was used to measure carbon isotope fractionation during reductive dehalogenation of hexachlorobenzene (HCB), pentachlorobenzene (PeCB), 1,2,3,5 tetrachlorobenzene (TeCB), 1,2,3,5-tetrabromobenzene (TeBB), and 1,3,5 tribromobenzene (TriBB). Strong evidence of isotope fractionation coupled to dehalogenation was not observed in the substrate, possibly due to the low solubilities of the highly halogenated benzene substrates and a dilution of the isotope signal. Nonetheless, we could measure a depletion of the delta13C value in the dichlorobenzene product during dechlorination of HCB, the sequential depletion and enrichment of delta13C value for trichlorobenzene in TeCB dechlorinating cultures, and the enrichment of delta13C during debromination of TriBB. This indicates that a measurable isotope fractionation occurred during reductive dehalogenation of highly halogenated chloro- and bromobenzenes in aquatic sediments. Thus, although more quantitative measurements will be needed, the data suggests that CSIA may have application for monitoring in situ microbial reductive dehalogenation of highly halogenated benzenes.

Watson on varying concentration of Chromium (Cr+6) on soil and its bioaccumulation: Perspectives on phytoremediation potential and phytostabilisation of chromium toxicity. AB - Chromium (Cr) contamination in soil is a growing concern in sustainable agricultural production and food safety. Remediation of Cr from contaminated soils is a challenging task which may not only help in sustaining agriculture but also in minimizing adverse environmental impacts. Pot culture experiments were performed with the application of varied concentration of Cr+6 to assess the Chromium accumulation potential of Lemongrass and to study the impact of toxic concentration of Cr+6 on morphological, physiological and biochemical parameters of the plant. The results showed an increasing accumulation trend of Chromium with increasing Chromium concentrations in both root and shoot of 60 days old Lemongrass plants, while the protein and chlorophyll contents decreased. Similarly, accumulation of Cr increased the levels of proline and antioxidant enzymes indicating the enhanced damage control activity. The potentiality of the plant with the capacity to accumulate and stabilize Cr compound in Cr contaminated soil by phytoremediation process has been explored in the present investigation. PMID- 29175408 TI - Circadian variations in the pharmacokinetics of capecitabine and its metabolites in rats. AB - Capecitabine, an orally available prodrug of 5-fluorouracil, is widely used to treat patients with colorectal cancer. Although various studies have shown circadian variations in plasma 5-fluorouracil concentrations during long-term infusion, it is still unknown whether circadian variations also exist following administration of capecitabine. The present study aimed to investigate whether the pharmacokinetics of capecitabine and its metabolites, including 5 fluorouracil, vary according to administration time in rats. Rats were orally administered capecitabine (180mg/kg) at 07:00 (23h after light onset, HALO), 13:00 (5 HALO), or 19:00h (11 HALO). Plasma concentrations of capecitabine and its metabolites, such as 5'-deoxy-5-fluorocytidine (5'-DFCR), 5'-deoxy-5 fluorouridine (5'-DFUR), and 5-fluorouracil, were determined after capecitabine administration. The results showed that the t1/2 and AUC0-infinity values of 5 fluorouracil differed as a function of the dosing time of capecitabine. The maximum and minimum mean t1/2 values of 5-fluorouracil were obtained when the drug was administered at 07:00h (23 HALO: 3.1+/-1.2h) and 13:00h (5 HALO: 1.5+/ 0.6h), respectively. The AUC0-infinity value of 5-fluorouracil at 07:00h (23 HALO: 533.9+/-195.7MUmol?h/L) was 1.8-fold higher than the value at 13:00h (5 HALO: 302.5+/-157.1MUmol?h/L). The clearance of 5-fluorouracil followed a cosine circadian curve, and the simulated population mean clearance was highest at rest times and lowest during active times in rats. The results for the plasma 5'-DFCR and 5'-DFUR levels indicated that circadian variations in the sequential metabolism of capecitabine to 5-fluorouracil would also affect plasma 5 fluorouracil levels following capecitabine administration. In conclusion, the pharmacokinetics of capecitabine and its metabolites, including 5-fluorouracil, varied according to time of dosing, suggesting that the capecitabine administration time is an important factor in achieving sufficient efficacy and reducing toxicity in patients. PMID- 29175409 TI - Are high-sensitivity cardiac troponin I values stable between preoperative visit and day of non-cardiac surgery? AB - BACKGROUND: It is unclear if cardiac troponin values are stable in patients prior to undergoing non-cardiac surgery, or if they tend to rise towards the day of surgery. METHODS: In this small pilot study (n=18) among patients with cardiac risk undergoing non-cardiac surgery, we determined if high-sensitivity cardiac troponin I (hscTnI) changes between the preoperative clinic visit and the day of surgery. HscTnI was measured on an Abbott Architect STAT (Abbott Laboratories, USA) platform. RESULTS: The mean duration between preoperative clinic visit and day of surgery was 8.7+/-2.8 (SD) days. Median hscTnI was 3.4ng/L [2.0-4.8, IQR] at the preoperative visit and 2.8ng/L [2.3-4.4] on the day of surgery (mean difference-0.24ng/L, 95% CI - 0.73 to 0.24ng/L, p=0.30). Only one patient had a large change (>50%) along with symptoms. DISCUSSION: Evidence from this small study suggests that cardiac troponin values are stable in most high-risk patients, absent clinical events, within 10days prior to non-cardiac surgery. PMID- 29175410 TI - InVitro, Ex Vivo, and In Vivo Evaluation of a Dual pH/Redox Responsive Nanoliposomal Sludge for Transdermal Drug Delivery. AB - A dual pH/redox responsive copper-glyglycine-prednisolone succinate-loaded nanoliposomal (NL) sludge was successfully synthesized and optimized using a Box Behnken design of experiments. Preformulation design variables indicated that relative ratios of phospholipids, considerably influences NL size, thus altering the degree of drug loading in the formulation. In vitro evaluation further confirmed optimum release kinetics of the NL sludge, corresponding closely to ex vivo permeation studies, demonstrating effective transdermal delivery of prednisone succinate (PS) through a pig skin model, which closely resembles human skin anatomy. The pH/redox stimuli responsiveness of the NL sludge further demonstrated superior properties in vivo using a Sprague-Dawley rat model. The NL sludge displayed the greatest release of PS within 24 h of evaluation, falling within the acceptable therapeutic range of PS dose efficiency. In vivo results further displayed the greatest absorption of PS under inflammatory induced conditions, thus confirming the unique pH/redox responsive properties of the NL sludge. It was thus confirmed that the copper-glyglycine-prednisolone succinate loaded NL sludge has significant potential for application in chronic inflammatory conditions such as tumor necrosis factor receptor-associated periodic syndrome (TRAPS), designed to release an effective dose of corticosteroid, as a transdermal drug delivery formulation, for effective therapeutic efficacy. PMID- 29175411 TI - Mechanistic Physiologically Based Pharmacokinetic (PBPK) Model of the Heart Accounting for Inter-Individual Variability: Development and Performance Verification. AB - Modern model-based approaches to cardiac safety and efficacy assessment require accurate drug concentration-effect relationship establishment. Thus, knowledge of the active concentration of drugs in heart tissue is desirable along with inter subject variability influence estimation. To that end, we developed a mechanistic physiologically based pharmacokinetic model of the heart. The models were described with literature-derived parameters and written in R, v.3.4.0. Five parameters were estimated. The model was fitted to amitriptyline and nortriptyline concentrations after an intravenous infusion of amitriptyline. The cardiac model consisted of 5 compartments representing the pericardial fluid, heart extracellular water, and epicardial intracellular, midmyocardial intracellular, and endocardial intracellular fluids. Drug cardiac metabolism, passive diffusion, active efflux, and uptake were included in the model as mechanisms involved in the drug disposition within the heart. The model accounted for inter-individual variability. The estimates of optimized parameters were within physiological ranges. The model performance was verified by simulating 5 clinical studies of amitriptyline intravenous infusion, and the simulated pharmacokinetic profiles agreed with clinical data. The results support the model feasibility. The proposed structure can be tested with the goal of improving the patient-specific model-based cardiac safety assessment and offers a framework for predicting cardiac concentrations of various xenobiotics.

AB - The study design is that lipophilic drug was encapsulated within dissolving microneedles (DMNs) for sustained-release delivery over 1 week. Etonogestrel (ENG), the progestogen used in hormonal contraceptives, was loaded in 2-layered DMNs in the form of microcrystal particles (MPs). In vitro release study indicated that ENG in the MP form could sustain drug release compared to noncrystal form. Hydroxypropyl methylcellulose and polyvinyl alcohol were used to prepare the fast dissolving needle tips and flexible back layer, respectively. The mechanical strength of microneedles was not affected even with the drug loading efficiency of 50.0% in needle tips. The penetration depth of DMNs in skin, observed using a confocal laser scanning microscope, was approximately 280 MUm. The tips of DMNs could be dissolved in rat skin within 1 h with a drug delivery efficiency of 63.8 +/- 2.0%. The pharmacokinetic study of DMN treatment in rats showed that the plasma levels of ENG were a dose-dependent profile and were much steadier than intradermal (ID) injections. There was no statistical difference between bioavailability of ENG treated with DMNs or ID injections (p >0.05). Therefore, the novel DMNs loaded with drug MP provided a potential minimally invasive route for ID sustained delivery of lipophilic drug. PMID- 29175413 TI - Status Epilepticus Decreases Brain Cytochrome P450 2D4 Expression in Rats. AB - Status epilepticus (SE) is a life-threatening neurological emergency characterized by frequent seizures. The present study aims at elucidating the effect of SE on CYP2D4 expression in the rat brain. To create a rat model of SE, Sprague-Dawley rats were intraperitoneally administered 10 mg/kg kainic acid. The CYP2D4 mRNA levels in the cortex and hippocampus of the SE rats were decreased by 0.38- and 0.39-fold, respectively. The protein level of octamer transcription factor 1 (Oct-1), which is involved in the transcriptional activation of CYP2D4 by binding to the CYP2D4 regulatory element, was also attenuated by 0.64- and 0.51-fold in these regions of the SE rat, suggesting that a reduction in Oct-1 may be involved in the CYP2D4 suppression. Yin yang 1 can function as a cofactor of histone deacetylase 1 and inhibit the binding of Oct-1 to the CYP2D4 regulatory element. The coimmunoprecipitation assay revealed that the interaction between yin yang 1 and histone deacetylase 1 in the cortex and hippocampus was enhanced during SE, indicating that this interaction is also responsible for the CYP2D4 suppression. This study clarified that SE led to a decrease in the expression of CYP2D4, thus altering the pharmacokinetics and efficacy of the drugs in the brain. PMID- 29175414 TI - The Effect of Drug Content Reduction on the In Vitro and In Vivo Properties of Levonorgestrel-Releasing Intravaginal Rings. AB - Intravaginal rings (IVRs) are an option for continuous administration of drugs in women. However, a considerable amount of excess drug often remains in the ring upon removal. The current study focuses on comparing 2 IVRs releasing levonorgestrel (LNG). Both formulations were designed to release 40 MUg of LNG daily, however, with a significant difference in the total amount of drug (10.6 vs. 176.9 mg). Numerical simulations and in vitro release rate testing were utilized in designing the IVRs and confirming the similarity of drug release. Moreover, a pharmacokinetic (PK) study was performed in 13 healthy Japanese women to investigate both formulations during the intended wearing period of 28 days. The primary PK metrics was the average concentration of LNG in plasma at defined time points under stable conditions. Statistical evaluation of the ratio of the main PK metrics indicated values almost in the bioequivalence range. Furthermore, drug content determinations for used and unused IVRs were analyzed for confirming the expected drug delivery in vivo. In summary, it was shown that with proper design, even major differences in the total drug content of IVR formulations might not result in significant effects in the in vitro and in vivo release properties. PMID- 29175415 TI - Multiple overlapping systematic reviews facilitate the origin of disputes: the case of thrombolytic therapy for pulmonary embolism. AB - OBJECTIVE: To explore disagreements in multiple systematic reviews (SRs) assessing the benefit-to-harm ratio of thrombolytic therapy in patients with intermediate-risk pulmonary embolism (PE). STUDY DESIGN AND SETTING: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and Database of Abstracts and Reviews of Effectiveness were searched up to April 14, 2016. We included SRs and guidelines that evaluated thrombolytic therapy, compared with anticoagulation alone, in intermediate-risk PE. We calculated pooled risk ratio (RR) and absolute risk difference (RD), with interquartile range (IQR), for all-cause mortality, recurrent PE, and major bleeding. RESULTS: We marked the Pulmonary Embolism Thrombolysis trial, the largest trial, as a research milestone. Since its release in 2014, 12 SRs (2-15 included trials) and two major guidelines were published. Studies were concordant in reporting that thrombolysis reduced all-cause mortality (median RD -1.55%, IQR -1.60% to -1.40%; median RR 0.55, IQR 0.48 0.61). Discordant results were found for major bleeding (median RD 4.70%, IQR 0.90%-5.70%), with SRs reporting results in opposite directions. Relevant magnitude of effects and precision for benefits and harms were never prespecified. CONCLUSION: Fourteen evidence syntheses were published within 25 months. Conclusions suggested mortality reduction associated with thrombolytics. Therapy harm was more dispersed and alternatively considered. Interpretation of the benefit-to-harm ratio was elusive, and modest incremental advantages might or not be important, facilitating the origin of disputes. PMID- 29175416 TI - Can Autofluorescence Guide Surgeons in the Treatment of Medication-Related Osteonecrosis of the Jaw? A Prospective Feasibility Study. AB - PURPOSE: The main limitation of surgical treatment of medication-related osteonecrosis of the jaw (MRONJ) is difficulty in defining resection margins. The aim of this study was to compare the efficacy of the surgeon's experience and autofluorescence-guided bone surgery to delimit resection margins for necrotic bone. MATERIALS AND METHODS: MRONJ requiring surgical treatment was classified according to American Association of Oral and Maxillofacial Surgeons staging. To detect vital bone and resection margins, patients of each stage were randomly assigned to 1 of 2 surgical groups: an autofluorescence-guided surgery (AF) group and a conventional surgery (non-AF) group based on the surgeon's experience. Bone samples from the 2 groups were analyzed histopathologically. The main outcomes were defined as the absence of bone exposure or infection at the time of evaluation. Infection was defined as the presence of swelling, pain, or numbness in the area. Measurements were collected preoperatively and 1 week, 1 month, 6 months, and 1 year after surgery. Statistical analysis included descriptive statistics and the Fisher exact test to evaluate eventual differences between the 2 surgical protocols. RESULTS: The 36 patients (21 women and 15 men) included in this study were equally divided into 2 groups according to the surgical protocol: 18 patients in the non-AF group and 18 in the AF group. Thirty-nine lesions were included in this analysis: 20 lesions in the non-AF group and 19 in the AF group. Histopathologic examination confirmed the necrotic nature of all bone samples. Statistical analysis showed no differences in necrotic bone exposure or signs of infections between the 2 surgical protocols at different times (P > .05). CONCLUSIONS: Although the VELscope appears to be useful in guiding bone resection margins in patients with MRONJ, autofluorescence does not appear to be superior to conventional surgical techniques in mucosal healing and quality of life. PMID- 29175417 TI - Association Between Polymorphisms in the Genes of Estrogen Receptors and the Presence of Temporomandibular Disorders and Chronic Arthralgia. AB - PURPOSE: The high prevalence of painful temporomandibular disorders (TMDs) in women suggests that estrogen and its receptors play a fundamental etiologic role in the development of this joint pathology through complex action mechanisms. The aim of this study was to evaluate the possible association between polymorphisms in the ESR1 (estrogen receptor-1) and ESRRB (estrogen-related receptor-beta) genes and the risk of simultaneous development of TMDs and pain in other joints in the body. MATERIALS AND METHODS: All participants were clinically evaluated for the presence of TMD (Research Diagnostic Criteria for TMD) and asked about the presence of chronic joint pain. The control group consisted of 72 patients without TMD and without pain. Participants with arthralgia were divided into 3 groups: with muscular TMD (n = 42), with articular TMD (n = 16), and without TMD and with systemic arthralgia (n = 82). Eight single-nucleotide polymorphisms in the ESR1 (rs12154178, rs1884051, rs2273206, rs7774230) and ESRRB (rs1676303, rs4903399, rs10132091, rs7151924) genes were investigated. The chi2 test and Student t and Mann-Whitney tests were used to assess the relevance of nominal and continuous variables, respectively. A P value less than .05 was considered significant. RESULTS: The TT (timin/timin) genotype for the ESR1 (rs2273206) gene was strongly associated with the risk of developing muscle TMDs and temporomandibular joint pain (P = .04). For the ESRRB (rs1676303) gene, an association was observed between the CC (cytosine/cytosine) genotype and the presence of articular TMDs associated with other chronic arthralgia (P = .02). These results were confirmed by the increased risk of developing articular TMDs associated with the C allele (P = .04). CONCLUSIONS: This study supports the hypothesis that changes in the ESR1 and ESRRB genes influence the presence of TMDs associated with chronic joint pain. PMID- 29175418 TI - Src family kinase tyrosine phosphorylates Toll-like receptor 4 to dissociate MyD88 and Mal/Tirap, suppressing LPS-induced inflammatory responses. AB - Src family kinases (SFKs) are a family of protein tyrosine kinases containing nine members: Src, Lyn, Fgr, Hck, Lck, Fyn, Blk, Yes, and Ylk. Although SFK activation is a major immediate signaling event in LPS/Toll-like receptor 4 (TLR4) signaling, its precise role has remained elusive due to various contradictory results obtained from a certain SFK member-deficient mice or cells. The observed inconsistencies may be due to the compensation or redundancy by other SFKs upon a SFK deficiency. The chemical rescuing approach was suggested to induce temporal and precise SFK activation in living cells, thereby limiting the chance of cellular adaption to a SFK-deficient condition. Using the rescuing approach, we demonstrate that restoring SFK activity not only induces tyrosine phosphorylation of TLR4, but also inhibits LPS-induced NFkappaB and JNK1/2 activation and consequently suppresses LPS-induced cytokine production. TLR4 normally recruits TIR domain-containing adaptors in response to LPS, however, temporally restored SFK activation disrupts the LPS-induced association of MyD88 and Mal/Tirap with TLR4. Additionally, using kinase-dead SFK-Lyn (Y397/508F) and constitutively active SFK-Lyn (Y508F), we found that the kinase-dead SFK inhibits TLR4 tyrosine phosphorylation with reduced binding affinity to TLR4, while the kinase-active SFK strongly binds to TLR4 and promotes TLR4 tyrosine phosphorylation, suggesting that SFK kinase activity is required for TLR4 tyrosine phosphorylation and TLR4-SFK interaction. Together, our results demonstrate that SFK activation induces TLR4 tyrosine phosphorylation, consequently dissociating MyD88 and Mal/Tirap from TLR4 and inhibiting LPS induced inflammatory responses, suggesting a negative feedback loop regulated by SFK-induced tyrosine phosphorylation in TLR4. PMID- 29175419 TI - Exogenous oxidants activate nuclear factor kappa B through Toll-like receptor 4 stimulation to maintain inflammatory phenotype in macrophage. AB - Disturbances in redox equilibrium in tissue can lead to inflammatory state, which is a mediatory factor in many human diseases. The mechanism(s) by which exogenous oxidants may activate an inflammatory response is not fully understood. Emerging evidence suggests that oxidant-induced Toll-like receptor 4 (TLR4) activation plays a major role in "sterile" inflammation. In the present study, we used murine macrophage RAW-Blue cells, which are chromosomally integrated with secreted embryonic alkaline phosphatase (SEAP) inducible by NF-kappaB. We confirmed the expression of TLR4 mRNA and protein in RAW-Blue cells by RT-PCR and Western blot, respectively. We showed that oxidants increased intracellular reactive oxygen species production and lipid peroxidation, which resulted in decreased intracellular total antioxidant capacity. Consistent with the actions of TLR4-specific agonist LPS-EK, exogenous oxidants increased transcriptional activity of NF-kappaB p65 with subsequent release of NF-kappaB reporter gene SEAP. These effects were blocked by pretreatment with TLR4 neutralizing pAb and TLR4 signaling inhibitor CLI-095. In addition, oxidants decreased the expression of IkappaBalpha with enhanced phosphorylation at the Tyr42 residue. Finally, oxidants and LPS-EK increased TNFalpha production, but did not affect IL-10 production, which may cause imbalance between pro- and anti-inflammatory processes, which CLI-095 inhibited. For biological relevance, we confirmed that oxidants increased release of TNFalpha and IL-6 in primary macrophages derived from TLR4-WT and TLR4-KO mice. Our results support the involvement of TLR4 mediated oxidant-induced inflammatory phenotype through NF-kappaB activation in macrophages. Thus exogenous oxidants may play a role in activating inflammatory phenotypes that propagate and maintain chronic disease states. PMID- 29175420 TI - alpha1A-Adrenoceptors activate mTOR signalling and glucose uptake in cardiomyocytes. AB - The capacity of G protein-coupled receptors to modulate mechanistic target of rapamycin (mTOR) activity is a newly emerging paradigm with the potential to link cell surface receptors with cell survival. Cardiomyocyte viability is linked to signalling pathways involving Akt and mTOR, as well as increased glucose uptake and utilization. Our aim was to determine whether the alpha1A-adrenoceptor (AR) couples to these protective pathways, and increased glucose uptake. We characterised alpha1A-AR signalling in CHO-K1 cells co-expressing the human alpha1A-AR and GLUT4 (CHOalpha1AGLUT4myc) and in neonatal rat ventricular cardiomyocytes (NRVM), and measured glucose uptake, intracellular Ca2+ mobilization, and phosphorylation of mTOR, Akt, 5' adenosine monophosphate activated kinase (AMPK) and S6 ribosomal protein (S6rp). In both systems, noradrenaline and the alpha1A-AR selective agonist A61603 stimulated glucose uptake by parallel pathways involving mTOR and AMPK, whereas another alpha1-AR agonist oxymetazoline increased glucose uptake predominantly by mTOR. All agonists promoted phosphorylation of mTOR at Ser2448 and Ser2481, indicating activation of both mTORC1 and mTORC2, but did not increase Akt phosphorylation. In CHOalpha1AGLUT4myc cells, siRNA directed against rictor but not raptor suppressed alpha1A-AR mediated glucose uptake. We have thus identified mTORC2 as a key component in glucose uptake stimulated by alpha1A-AR agonists. Our findings identify a novel link between the alpha1A-AR, mTORC2 and glucose uptake, that have been implicated separately in cardiomyocyte survival. Our studies provide an improved framework for examining the utility of alpha1A-AR selective agonists as tools in the treatment of cardiac dysfunction. PMID- 29175422 TI - Targeting CXCR7 improves the efficacy of breast cancer patients with tamoxifen therapy. AB - Chemokine (C-X-C motif) receptor 7 (CXCR7) has been established to be involved in breast cancer (BCa) progression. However, the role of CXCR7 in different subtype of BCa still remains unclear. Here we note that CXCR7 expression is significantly amplified in Luminal type BCa tissues as compared with Her2 and TNBC types through data-mining in TCGA datasets, and its protein level positively correlates with ERalpha expression by staining of human BCa tissue. Interestingly, alteration of CXCR7 expression in Luminal type BCa cells is able to modulate the expression of ERalpha through ubiquitination at post-translational level. Additionally, overexpression of CXCR7 in these cells greatly induces 4-OHT insensitivity in vitro and is associated with earlier recurrence in patients with tamoxifen therapy. Notably, silencing ERalpha expression potentially rescues the sensitivity of the above cells to 4-OHT, suggesting that elevated level of ERalpha is responsible for CXCR7-induced 4-OHT insensitivity in Luminal type BCa. Finally, mechanistic analyses show that the reduced BRCA1 (ubiquitin E3 ligase) and elevated OTUB1 (deubiquitinase) expression, which are regulated by CXCR7/ERK1/2 signaling pathway, are responsible for stabilizing ERalpha protein. In conclusion, our results suggest that targeting CXCR7 may serve as a potential therapeutic strategy for improving the efficacy of BCa patients with tamoxifen therapy. PMID- 29175423 TI - Tropisetron enhances recognition memory in rats chronically treated with risperidone or quetiapine. AB - While impairments of cognition in schizophrenia have the greatest impact on long term functional outcome, the currently prescribed treatments, antipsychotic drugs (APDs), do not effectively improve cognition. Moreover, while more than 20 years have been devoted to the development of new drugs to treat cognitive deficits in schizophrenia, none have been approved to date. One area that has not been given proper attention at the preclinical or clinical stage of drug development is the chronic medication history of the test subject. Hence, very little is known about how chronic treatment with drugs that affect multiple receptors like APDs influence the response to a potential pro-cognitive agent. Therefore, the purpose of this study was to evaluate the alpha7 nicotinic acetylcholine receptor (alpha7 nAChR) partial agonist, tropisetron in rats chronically treated with APDs with distinct pharmacological profiles. Rats were treated orally with either risperidone (2.5 mg/kg/day) or quetiapine (25.0 mg/kg/day) for 30 or 90 days and then an acute injection of vehicle or tropisetron (3.0 mg/kg) was administered before training in a novel object recognition (NOR) task. After a 48 h delay (when recollection of the familiar object was impaired in vehicle-treated animals) neither 30 nor 90 days of risperidone or quetiapine treatment improved NOR performance. In contrast, tropisetron markedly improved NOR performance in rats treated with either APD for 30 or 90 days. These animal data reinforce the argument that two commonly prescribed APDs are not pro-cognitive agents and that alpha7 nAChR ligands like tropisetron have potential as adjunctive treatments in schizophrenia. PMID- 29175421 TI - A review of hydrogen sulfide (H2S) donors: Chemistry and potential therapeutic applications. AB - Hydrogen sulfide (H2S) is a ubiquitous small gaseous signaling molecule, playing an important role in many physiological processes and joining nitric oxide and carbon monoxide in the group of signaling agents termed gasotransmitters. Endogenous concentrations of H2S are generally low, making it difficult to discern precise biological functions. As such, probing the physiological roles of H2S is aided by exogenous delivery of the gas in cell and animal studies. This need for an exogenous source of H2S provides a unique challenge for chemists to develop chemical tools that facilitate the study of H2S under biological conditions. Compounds that degrade in response to a specific trigger to release H2S, termed H2S donors, include a wide variety of functional groups and delivery systems, some of which mimic the tightly controlled endogenous production in response to specific, biologically relevant conditions. This review examines a variety of H2S donor systems classified by their H2S-releasing trigger as well as their H2S release profiles, byproducts, and potential therapeutic applications. PMID- 29175424 TI - New spectrophotometric assay for assessments of catalase activity in biological samples. AB - A novel, simple, and accurate colorimetric assay was established for assessments of catalase activity in biological fluids and tissues. H2O2 dissociation rates are directly proportional to catalase activity, and the principle of the present assay is based on reactions of ammonium metavanadate with H2O2 under acidic conditions. The resulting reduction of vanadium (V) to vanadium (III) produces a red-orange peroxovanadium complex with absorbance maxima at 452 nm. Biological samples containing catalase were incubated with 50-mM phosphate buffer solution containing 10-mM H2O2 as a substrate for two min. Subsequently, ammonium metavanadate in sulfuric acid was used as an indicator reagent and was added to reaction mixtures to determine remaining H2O2 concentrations. The precision of the present novel assay was indicated by coefficients of variation of 4.09% within runs and 2.56% between runs. Moreover, in experiments with homogenized red blood cell solutions, peroxovanate and dichromate assays of catalase activities were highly correlated (r = 0.993). In further experiments, we demonstrated application of the peroxovanadate method to assessments of catalase activity in bacterial and liver homogenates. The present method is accurate, simple, rapid, and inexpensive and can be used for routine clinical measurements and scientific investigations. PMID- 29175425 TI - Modelling the effects of cutting off infected branches and replanting on fire blight transmission using Filippov systems. AB - Fire blight is one of the most devastating plant diseases in the world. This paper proposes a Filippov fire-blight model incorporating cutting off infected branches and replanting susceptible trees. The Filippov-type model is formulated by considering that no control strategy is taken if the number of infected trees is less than an infected threshold level Ic; further, we cut off infected branches once the number of infected trees exceeds Ic; meanwhile, we replant trees if the number of susceptible trees is less than a susceptible threshold level Sc. The global dynamical behaviour of the Filippov system is investigated. It is shown that model solutions ultimately converge to the positive equilibrium that lies in the region above Ic, or below Ic, or on I=Ic, as we vary the susceptible and infected threshold values Sc and Ic. Our results indicate that proper combinations of the susceptible and infected threshold values based on the threshold policy can lead the number of infected trees to an acceptable level, when complete eradication is not economically desirable. PMID- 29175426 TI - Competition of energy between active transport and vesicle fusion at the origin of intracellular gradient fields. AB - It has been reported that the ionic patterns of hyphal growth can be explained by a weakening of the active transport at the tip at the expense of other biosynthesis processes, from which results energy transport from the proximal cells to the apical ones (Potapova et al. 1988). We present here a theory to support this hypothesis, whose extent is much more general than the initial frame where it has been formulated. It can be summarized in two basics mechanisms, one coupling active transport of the plasma membrane, electric potential and vesicle fusion, the other coupling the Ca2+-ATPase of the endoplasmic reticulum and vesicle fusion. For some values of parameters introduced in the theory, the uniform state of the cell becomes unstable, at the origin of intracellular gradient fields. Theoretical ionic patterns are spontaneously produced, which can be satisfactorily compared to several observed in and around tip-growing cells. PMID- 29175427 TI - Therapeutic drug monitoring of ponatinib using a simple high-performance liquid chromatography method in Japanese patients. AB - A simple and highly sensitive high-performance liquid chromatography (HPLC) method was developed for the quantification of ponatinib in human plasma. The developed HPLC method was validated based on International D.S. Food and Drug Administration guidelines. This technique utilized a solid-phase extraction step and required only 200MUL plasma for a single analysis. The lower limit of quantification for ponatinib was 1.0ng/mL. Coefficients of variation and accuracies for intra- and interday assays were less than 10.8% and within 13.7%, respectively. The precision and accuracy of our HPLC assay was suitable for pharmacokinetic studies of ponatinib. On day 8 after beginning ponatinib therapy with an initial dose of 15mg, patients having a ponatinib C0 of less than 23ng/mL by HPLC may require a dose adjustment to 30mg to obtain a C0 of 23ng/mL of more. The median ponatinib C0 in 6 Japanese patients taking a 15mg daily dose was 24.6ng/mL, which was greater than the target concentration of 23ng/mL, and that of patients taking 30mg increased to a plasma concentration of 48.0ng/mL. This novel treatment strategy using the HPLC method developed herein may be useful for routine ponatinib therapy. PMID- 29175428 TI - Developing an in vitro artificial sebum model to study Propionibacterium acnes biofilms. AB - AIM: The aim of the present study was to develop a new model system to study Propionibacterium acnes biofilms. This model should be representative for the conditions encountered in the pilosebaceous unit. METHODS AND RESULTS: The new model, consists of an artificial sebum pellet supported by a silicone disc. Sebum pellets were inoculated with various P. acnes strains isolated from both normal and acneic skin. Growth and biofilm formation was verified by conventional plating at different time points, as well as by resazurin assays and fluorescence microscopy after LIVE/DEAD staining. The artificial sebum pellets were also used in assays to measure the production of certain virulence factors implicated in the pathogenesis of acne, including lipase, protease and the presence of CAMP factors. CONCLUSION: The artificial sebum model can sustain biofilm growth of P. acnes, as was determined by increasing CFU counts for up to 1 week after inoculation. Metabolic activity and biofilm formation were confirmed using resazurin staining and fluorescence microscopy respectively. The production of virulence factors in this model was demonstrated as well.

PMID- 29175430 TI - Medical Students' Acquisition of Adolescent Interview Skills after Coached Role Play. AB - STUDY OBJECTIVE: To develop and evaluate an educational activity designed to teach the adolescent Home, Education and employment, Eating, Activities, Drugs, Sexuality, Suicide/depression, and Safety (HEADS) examination. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: Participants were third year medical students in their pediatric clerkships. Students received an article on the HEADS interview and attended an adolescent medicine educational session. The session included individualized goal-setting and coached role play. Students' skills in doing a HEADS interview were evaluated through a standardized patient encounter (SPE) with a checklist and a retrospective pre- and post-test survey. The SPE checklist was used to assess whether the students included questions in 6 key areas of a HEADS interview. RESULTS: One hundred fifty-two students participated. During the SPE, 90% of students queried the adolescent's home life, 91% education, 82% activities, 84% drug/substance abuse, 95% sexual history, and 61% symptoms of depression. Pre- and postintervention data were compared using the Kruskal-Wallis Test and showed a statistically significant difference in the students' ability to list key topic areas of the HEADS exam (P < .001) and to use the skills needed for an adolescent interview using the HEADS exam (P < .001). CONCLUSION: After an introduction to the HEADS examination, most students covered almost all of the topic areas of this screening interview during a SPE. Only three-fifths of the students, however, included questions about symptoms of depression. Coached role play with goal-setting facilitated effective learning of this approach to adolescent interviewing. PMID- 29175431 TI - A cloud-based framework for large-scale traditional Chinese medical record retrieval. AB - INTRODUCTION: Electronic medical records are increasingly common in medical practice. The secondary use of medical records has become increasingly important. It relies on the ability to retrieve the complete information about desired patient populations. How to effectively and accurately retrieve relevant medical records from large- scale medical big data is becoming a big challenge. Therefore, we propose an efficient and robust framework based on cloud for large scale Traditional Chinese Medical Records (TCMRs) retrieval. METHODS: We propose a parallel index building method and build a distributed search cluster, the former is used to improve the performance of index building, and the latter is used to provide high concurrent online TCMRs retrieval. Then, a real-time multi indexing model is proposed to ensure the latest relevant TCMRs are indexed and retrieved in real-time, and a semantics-based query expansion method and a multi- factor ranking model are proposed to improve retrieval quality. Third, we implement a template-based visualization method for displaying medical reports. RESULTS: The proposed parallel indexing method and distributed search cluster can improve the performance of index building and provide high concurrent online TCMRs retrieval. The multi-indexing model can ensure the latest relevant TCMRs are indexed and retrieved in real-time. The semantics expansion method and the multi-factor ranking model can enhance retrieval quality. The template-based visualization method can enhance the availability and universality, where the medical reports are displayed via friendly web interface. CONCLUSIONS: In conclusion, compared with the current medical record retrieval systems, our system provides some advantages that are useful in improving the secondary use of large-scale traditional Chinese medical records in cloud environment. The proposed system is more easily integrated with existing clinical systems and be used in various scenarios. PMID- 29175432 TI - DNA mismatch repair proteins MLH1 and PMS2 can be imported to the nucleus by a classical nuclear import pathway. AB - MLH1 and PMS2 proteins form the MutLalpha heterodimer, which plays a major role in DNA mismatch repair (MMR) in humans. Mutations in MMR-related proteins are associated with cancer, especially with colon cancer. The N-terminal region of MutLalpha comprises the N-termini of PMS2 and MLH1 and, similarly, the C-terminal region of MutLalpha is composed by the C-termini of PMS2 and MLH1, and the two are connected by linker region. The nuclear localization sequences (NLSs) necessary for the nuclear transport of the two proteins are found in this linker region. However, the exact NLS sequences have been controversial, with different sequences reported, particularly for MLH1. The individual components are not imported efficiently, presumably due to their C-termini masking their NLSs. In order to gain insights into the nuclear transport of these proteins, we solved the crystal structures of importin-alpha bound to peptides corresponding to the supposed NLSs of MLH1 and PMS2 and performed isothermal titration calorimetry to study their binding affinities. Both putative MLH1 and PMS2 NLSs can bind to importin-alpha as monopartite NLSs, which is in agreement with some previous studies. However, MLH1-NLS has the highest affinity measured by a natural NLS peptide, suggesting a major role of MLH1 protein in nuclear import compared to PMS2. Finally, the role of MLH1 and PMS2 in the nuclear transport of the MutLalpha heterodimer is discussed. PMID- 29175433 TI - Detection of AmpC beta-lactamase-producing Gram-negative bacteria by matrix assisted laser desorption/ionization time-of-flight mass spectrometry. AB - BACKGROUND: Rapid detection of AmpC-producing strains of Gram-negative bacteria is beneficial for patient care. Matrix-assisted laser desorption/ionization time of-flight mass spectrometry (MALDI-TOF MS) is a novel method that has demonstrated the resistance of a strain to beta-lactam antibiotics by determining the molecular structure of an antibiotic and its degradation products. AIM: To study the detection of AmpC-producing Gram-negative bacteria by MALDI-TOF MS and to determine whether the method can be used in clinical practice. METHODS: A total of 105 strains were detected by determining their phenotypes and sequence analysis. Sixty-nine well-characterized AmpC-producing and 36 non-AmpC-producing strains were studied. The bacteria were incubated in different reaction buffer solutions (10 mM NH4HCO3/0.005% sodium dodecyl sulphate at pH 8.0) containing cefotaxime (0.50 mg/mL), ceftazidime (0.25 mg/mL), ceftriaxone (0.50 mg/mL), cefepime (0.50 mg/mL), and cefoxitin (0.25 and 0.50 mg/mL), respectively. The mixture was centrifuged at 13,000 g for 2 min, and the supernatant analysed by MALDI-TOF MS after incubation for 30, 60, 90, 120, and 240 min. Antibiotic hydrolysed and decarboxylated peaks were identified. FINDINGS: When incubated for 90 min, hydrolysed cefotaxime formed peaks at 434 and 494 Da, and the sensitivity and specificity for detection of AmpC-producing strains were 85.5% (59/69) and 88.9% (32/36). When incubated for 4 h, hydrolysed ceftazidime formed peaks at 563 and 587 Da, and the sensitivity and specificity were 89.9% (62/69) and 94.5% (34/36), respectively. For hydrolysed ceftriaxone (0.5 mg/mL), cefepime (0.5 mg/mL) and two concentrations of cefoxitin (0.25 and 0.5 mg/mL), no peaks amenable to analysis were identified. CONCLUSION: This study demonstrated that MALDI-TOF MS can rapidly detect AmpC-producing strains.

AB - BACKGROUND: Studies often ignore time-varying confounding or may use inappropriate methodology to adjust for time-varying confounding. AIM: To estimate the effect of intensive care unit (ICU)-acquired bacteraemia on ICU mortality and discharge using appropriate methodology. METHODS: Marginal structural models with inverse probability weighting were used to estimate the ICU mortality and discharge associated with ICU-acquired bacteraemia among patients who stayed more than two days at the general ICU of a London teaching hospital and remained bacteraemia-free during those first two days. For comparison, the same associations were evaluated with (i) a conventional Cox model, adjusting only for baseline confounders and (ii) a Cox model adjusting for baseline and time-varying confounders. FINDINGS: Using the marginal structural model with inverse probability weighting, bacteraemia was associated with an increase in ICU mortality (cause-specific hazard ratio (CSHR): 1.29; 95% confidence interval (CI): 1.02-1.63) and a decrease in discharge (CSHR: 0.52; 95% CI: 0.45-0.60). By 60 days, among patients still in the ICU after two days and without prior bacteraemia, 8.0% of ICU deaths could be prevented by preventing all ICU-acquired bacteraemia cases. The conventional Cox model adjusting for time varying confounders gave substantially different results [for ICU mortality, CSHR: 1.08 (95% CI: 0.88-1.32); for discharge, CSHR: 0.68 (95% CI: 0.60-0.77)]. CONCLUSION: In this study, even after adjusting for the timing of acquiring bacteraemia and time-varying confounding using inverse probability weighting for marginal structural models, ICU-acquired bacteraemia was associated with a decreased daily ICU discharge risk and an increased risk of ICU mortality.

AB - INTRODUCTION: The antiplatelet effect of low-dose aspirin in patients with type 2 diabetes (T2DM) without cardiovascular disease (CVD) has not been thoroughly explored. We investigated if platelet aggregation increased during the standard 24-hour aspirin dosing interval in patients with T2DM compared to non-diabetic controls. Furthermore, we evaluated baseline platelet aggregation, the acute effects of aspirin on platelet aggregation and platelet turnover. MATERIALS AND METHODS: We included 21 patients with T2DM and 21 age and sex-matched controls. Platelet aggregation was measured by impedance aggregometry (Multiplate(r) Analyzer) and markers of platelet turnover by flow cytometry (Sysmex(r) XE-5000). Blood samples were obtained at baseline and 1h after administration of 75mg of aspirin. Participants were then treated for 6days with once-daily aspirin, and blood sampling was repeated 1h and 24h after aspirin intake. RESULTS: After 6days of treatment, platelet aggregation levels increased during the 24-hour aspirin dosing interval in both patients and controls (p<0.001) with no difference between patients and controls. At baseline, patients with diabetes had increased platelet aggregation compared to controls (p=0.03). Platelet aggregation was reduced after the first dose of aspirin and significantly further reduced after six days of treatment (p<0.001). Patients with T2DM had numerically higher immature platelet count compared to controls (p=0.09), indicating an increased platelet turnover. CONCLUSION: Patients with T2DM without a history of CVD and controls had increased platelet aggregation at the end of the standard 24-hour dosing interval of aspirin. Further, aspirin-naive T2DM patients had increased platelet aggregation compared to controls. PMID- 29175436 TI - 3D Chromatin Architecture of Large Plant Genomes Determined by Local A/B Compartments. AB - The spatial organization of the genome plays an important role in the regulation of gene expression. However, the core structural features of animal genomes, such as topologically associated domains (TADs) and chromatin loops, are not prominent in the extremely compact Arabidopsis genome. In this study, we examine the chromatin architecture, as well as their DNA methylation, histone modifications, accessible chromatin, and gene expression, of maize, tomato, sorghum, foxtail millet, and rice with genome sizes ranging from 0.4 to 2.4 Gb. We found that these plant genomes can be divided into mammalian-like A/B compartments. At higher resolution, the chromosomes of these plants can be further partitioned to local A/B compartments that reflect their euchromatin, heterochromatin, and polycomb status. Chromatins in all these plants are organized into domains that are not conserved across species. They show similarity to the Drosophila compartment domains, and are clustered into active, polycomb, repressive, and intermediate types based on their transcriptional activities and epigenetic signatures, with domain border overlaps with the local A/B compartment junctions. In the large maize and tomato genomes, we observed extensive chromatin loops. However, unlike the mammalian chromatin loops that are enriched at the TAD border, plant chromatin loops are often formed between gene islands outside the repressive domains and are closely associated with active compartments. Our study indicates that plants have complex and unique 3D chromatin architectures, which require further study to elucidate their biological functions. PMID- 29175437 TI - An Uncanonical CCCH-Tandem Zinc-Finger Protein Represses Secondary Wall Synthesis and Controls Mechanical Strength in Rice. AB - Secondary walls, which represent the bulk of biomass, have a large impact on plant growth and adaptation to environments. Secondary wall synthesis is switched and regulated by a sophisticated signaling transduction network. However, there is limited understanding of these regulatory pathways. Here, we report that ILA1 interacting protein 4 (IIP4) can repress secondary wall synthesis. IIP4 is a phosphorylation substrate of an Raf-like MAPKKK, but its function is unknown. By generating iip4 mutants and relevant transgenic plants, we found that lesions in IIP4 enhance secondary wall formation. Gene expression and transactivation activity assays revealed that IIP4 negatively regulates the expression of MYB61 and CESAs but does not bind their promoters. IIP4 interacts with NAC29/NAC31, the upstream regulators of secondary wall synthesis, and suppresses the downstream regulatory pathways in plants. Mutagenesis analyses showed that phosphomimic IIP4 proteins translocate from the nucleus to the cytoplasm, which releases interacting NACs and attenuates its repression function. Moreover, we revealed that IIPs are evolutionarily conserved and share unreported CCCH motifs, referred to as uncanonical CCCH-tandem zinc-finger proteins. Collectively, our study provides mechanistic insights into the control of secondary wall synthesis and presents an opportunity for improving relevant agronomic traits in crops. PMID- 29175438 TI - Gestational 3,3',4,4',5-pentachlorobiphenyl (PCB 126) exposure disrupts fetoplacental unit: Fetal thyroid-cytokines dysfunction. AB - Exposure to polychlorinated biphenyls (PCBs) is related to several endocrine disorders. This study examined the effect of maternal exposure of 3,3',4,4',5 pentachlorobiphenyl (PCB 126) on the fetoplacental unit and fetal thyroid cytokine axis during the pregnancy. Pregnant albino rats received PCB 126 (20 or 40MUg/kgb.wt.) by oral gavage from gestation day (GD) 1 to 20. Potential effects of PCB 126 were evaluated by following the histopathological changes in the placenta by Haematoxylin and Eosin (H&E) stain and measuring the maternofetal thyroid axis (ELIZA), maternofetal body weight, and fetal growth markers (ELIZA), and cytokines (ELIZA) at embryonic day (ED) 20. Placental tissues of both treated groups showed hyperemia, hemorrhage, degeneration and apoptosis in labyrinth layer and spiral artery at GD 20. Both administrations of PCB 126 elevated serum thyrotropin (TSH) concentration, and decreased free thyroxine (FT4) and free triiodothyronine (FT3) concentrations, resulting in a maternofetal hypothyroidism. The presence of hypothyroidism increased fetal serum concentration of transforming growth factor-beta (TGF-beta), leptin (LEP), tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), and decreased the fetal serum insulin growth factor-I (IGF-I), IGF-II, insulin, adiponectin (ADP), and growth hormone (GH) in both treated groups at ED 20. However, the increase in resistin (RETN) and interferon-gamma (IFN-gamma) was non-significant in low-dose group and highly significant in high-dose group. Simultaneously, the reduction in body weight of the dams and fetuses was observed in both PCB 126 groups of examined day with respect to the control group. The maternal PCB 126 distorted the fetoplacental unit might disrupt the fetal thyroid-cytokines axis and prenatal development. PMID- 29175439 TI - Lipid coated chitosan-DNA nanoparticles for enhanced gene delivery. AB - Chitosan as a polycationic non-viral vector for gene delivery has the advantage of being a biocompatible and biodegradable polymer. However, without laborious chemical modifications to its structure, it is of limited use as a gene delivery vehicle due to its low ability to efficiently transfect under physiological conditions. To address this problem, we developed novel liposome encapsulated chitosan nanoparticles; lipochitoplexes (LCPs). Chitosan nanoparticles (CsNPs) were obtained using the ionic gelation technique. For this purpose, an ultrapure low molecular weight chitosan with a high degree of deacetylation was cross linked using polyanionic tripolyphosphate resulting in efficient entrapment of plasmid DNA (pDNA) inside the nanoparticles. LCPs were prepared by incubating chitosan nanoparticles together with anionic liposomes (DPPC/Cholesterol). The LCPs offered better pDNA protection, reduced cytotoxicity and at least twofold increase in the transfection efficiency under physiological conditions. The efficiency of our delivery vehicle was also proved in vivo in the chorioallantoic membrane model (CAM). LCPs were able to transfect the CAM without traumatising the surrounding blood vessels. This new biocompatible composite system devoid of chemical modifications, organic solvents and harsh production conditions makes it an optimal gene delivery vehicle for in vivo applications offering new insights into the field of non-viral gene therapy. PMID- 29175440 TI - Liposomes encapsulating native and cyclodextrin enclosed paclitaxel: Enhanced loading efficiency and its pharmacokinetic evaluation. AB - Combination strategy involving cyclodextrin (CD) complexation and liposomal system was investigated for Paclitaxel (PTX) to improve loading. Complexation was done using 2,6-di-O-methylbetacyclodextrin (DMbetaCD). Sterically stabilized double loaded PEGylated liposomes (DLPLs) containing PTX and PTX-DMbetaCD complex were prepared by thin film hydration. Physicochemical characterization of complex and prepared DLPLs was carried out. Cytotoxic potential, hemolytic potential and pharmacokinetics of DLPLs were tested in comparison to Taxol(r). Aqueous solubility of PTX increased by almost 3 * 104 folds due to complexation with DMbetaCD as compared to pure drug solubility. Liposomal system was found to have 162.8 +/- 4.1 nm size, zeta potential of -5.6 +/- 0.14 mV and 2-fold increase in drug loading to 5.8 mol % for PTX due to double loading. DLPLs had low hemolytic potential and higher cytotoxicity on SKOV3 cells with improvement in IC50 value by 4.2 folds as compared to Taxol(r) at 48 h. The anti-angiogenic potential of DLPLs was confirmed by 1.33 folds lesser wound recovery in SKOV3 cells compared to Taxol(r). In-vivo pharmacokinetic evaluation of DLPLs in rats substantiates improvement in circulation time, higher plasma concentration and decreased clearance rate compared to Taxol(r). An efficacious system with improved loading and pharmacokinetics was formulated as potential alternative for currently marketed PTX formulation. PMID- 29175441 TI - Emotional ratings of high- and low-calorie food are differentially associated with cognitive restraint and dietary restriction. AB - Dietary restraint is a robust risk factor for binge eating and eating disorders, which may partially result from increased reward reactivity to food in individuals who attempt to diet. However, research examining the association between dietary restraint and reactivity to food cues is mixed. Mixed findings may reflect distinct relations between food cue reactivity and different dimensions of dietary behavior; attempts to diet (cognitive restraint) may be associated with increased positive evaluations of food, whereas actual reduction in food intake (dietary restriction) may be achieved through decreased reactivity to food cues. The aim of the current study was to examine whether cognitive restraint and dietary restriction, as assessed via subscales on a recently developed multidimensional measure of eating pathology (i.e., Eating Pathology Symptoms Inventory [EPSI]), are differentially associated with emotional evaluations of high- and low-calorie food. Female participants (N = 203) viewed 12 high-calorie (i.e., sweet, savory) and 12 low-calorie (i.e., fruits, vegetables) food images, as well as 36 standard emotional images. Images were rated on the dimensions of valence, arousal, and craving using the Self Assessment Manikin. Cognitive restraint was correlated with greater pleasure and craving ratings of low-calorie, but not high-calorie, foods. In contrast, dietary restriction was related to reduced pleasure and craving ratings for both high- and low-calorie foods. Findings suggest that cognitive restraint may be associated with a preference for low-calorie foods; whereas dietary restriction may relate to reduced sensitivity to the hedonic and motivational value of food, regardless of caloric content. Results also provide support for the distinction between cognitive restraint and dietary restriction, as assessed via the EPSI. PMID- 29175442 TI - Transcriptome profiling provides gene resources for understanding gill immune responses in Japanese flounder (Paralichthys olivaceus) challenged with Edwardsiella tarda. AB - Marine organisms are commonly under threats from various pathogens. Edwardsiella tarda is one of the fish pathogens that seriously infect cultured and wild fish species. Bacteremia caused by E. tarda can be a fatal disease in humans. Fish gill is a mucosa-associated lymphoid tissue that directly contacted with sea water. Generating gill transcriptomic resources that challenged by E. tarda is crucial for understanding the molecular mechanisms underlying gill immune responses. In this study, we performed transcriptome profiling of gene expression in Japanese flounder gills (Paralichthys olivaceus) challenged by E. tarda with different stress duration. An average of 40 million clean reads per library were obtained, of which approximately 83.2% were successfully mapped to the reference genome. 456 and 1037 differential expressed genes (DEGs) were identified at 8 h and 48 h post-injection, respectively. Gene annotation analysis and protein protein interaction networks were conducted to obtain the key interaction relationships of immune-related DEGs during pathogens infection. 24 hub genes with multiple protein-protein interaction relationships or involved in multiple KEGG signaling pathways were discovered and validated by qRT-PCR. These hub genes mainly participated in Leukocyte transendothelial migration signaling pathway, B cell receptor signaling pathway, Wnt signaling pathway and Apoptosis signaling pathway. This study represents the first gill transcriptomic analysis based on protein-protein interaction networks in fish and provides valuable gene resources for understanding the fish gill immunity, which can pave the way to understand the molecular mechanisms of immune responses with E. tarda infection. PMID- 29175443 TI - Intracellular TLR22 acts as an inflammation equalizer via suppression of NF kappaB and selective activation of MAPK pathway in fish. AB - TLR22, a typical member of the fish-specific TLRs, is a crucial sensor in virally triggered innate immune signalling retained from natural selection. To elucidate the role of the TLR22-specific signalling cascade mechanism, we provide evidence that the double-stranded (ds) RNA-sensor TLR22 positively regulates the ERK pathway and negatively regulates the JNK, p38 MAP kinase and NF-kappaB pathway. Here, we show that TLR22 restrains NF-kappaB activation and IFN (interferon) beta and AP-1 (activator protein-1) promoter binding (impairing "primary response" genes (TNF and IL-1)), induces "secondary response" genes (IL-12 and IL-6) and mediates the irregular expression of inflammatory genes. Therefore, TLR22 promotes ERK phosphorylation but impairs the JNK and p38 MAP kinases and IkappaB phosphorylation. Additionally, TLR22 controls the excessive generation of reactive oxygen species (ROS) to avoid damaging the organism. The specific kinetics of TLR22 depends on its distinct cellular localization. We demonstrate that TLR22 is an intracellular receptor localized in the endosome, and the TLR22 TIR domain is the functional structure inducing the signalling cascade post-viral replication in the body. As mentioned above, our data reveal a novel mechanism whereby TLR22-induced positive adjustment and negative regulation evolved independently to avoid harmful and inappropriate inflammatory responses. PMID- 29175444 TI - 17beta-estradiol suppresses carboxylesterases by activating c-Jun/AP-1 pathway in primary human and mouse hepatocytes. AB - In order to study the influence of estrogen on carboxylesterases, we investigated the effects of 17beta-estradiol on CES1 (Ces1d) and CES2 (Ces1e) in human and mouse hepatocytes. After being treated with 17beta-estradiol, the mRNA levels of CES1 and CES2 decreased by 29-39% and 28-55%, respectively, in the human hepatocytes from four donors. Consistently, the hydrolysis of para nitrophenylacetate decreased markedly by 32% induced by 17beta-estradiol. Moreover, 17beta-estradiol decreased CES1 and CES2 by 45% and 47% respectively at protein levels. The response of altered expression of Ces1d (CES1) and Ces1e (CES2) to 17beta-estradiolin in mouse hepatocytes was very similar to that in the human hepatocytes. Further, the decreased Ces1d and Ces1e expression induced by 17beta-estradiol could be abolished by SP600125, an inhibitor of AP-1, both at mRNA and protein levels. Likewise, the increased c-Jun expression induced by 17beta-estradiol could almost be abolished by SP600125. In vivo, the expression of Ces1d, Ces1e and the hydrolytic activity of liver were higher in the ovariectomized female mice(OVX) than those in control mice(SHAM). However, when 17beta-estradiol was administrated, the expression of Ces1d, Ces1e and the hydrolytic activity of liver in the ovariectomized female mice (OVX+E2) became restored to their normal levels. Taken together, 17beta-estradiol suppresses carboxylesterases by activating c-Jun/AP-1 pathway in primary human and mouse hepatocytes. The findings can offer the potential gains in the safety and efficacy of pharmacotherapy for women, especially for pregnant and menopausal women. PMID- 29175445 TI - Adipocyte biology in breast cancer: From silent bystander to active facilitator. AB - Adipocytes account for the largest proportion among the cells that comprise breast tissue; therefore, they are considered to be a critical cell type in the tumor microenvironment of breast cancer. In breast cancer, adipocytes are not only found adjacent to cancer cells, but they also play an active role in the entire process of cancer development, progression, metastasis, and treatment response. Factors including the secretion of adipokines such as leptin and adiponectin, as well as autotaxin, interleukin 6, tumor necrosis factor alpha, and hepatic growth factor, metabolic remodeling that supports the growth of breast cancer by transfer of fatty acids to increase mitochondrial beta oxidation, extracellular matrix remodeling and endotrophin production from type IV collagen, and cancer-associated fibroblast phenotype changes have all been implicated in this comprehensive process. Moreover, adipocytes may act as obstacles to therapy, as they are involved in mechanisms of resistance against various breast cancer treatments. Adipose tissues may also be a reservoir for dormant tumor cells during postsurgical autologous fat grafting. Thus, adipocytes, and the processes and pathways in which they are involved, could be effective therapeutic targets for breast cancer. In this review, we focus on the current understanding of adipocyte biology as it affects breast cancer. PMID- 29175446 TI - Phencyclidine increased while isolation rearing did not affect progressive ratio responding in rats: Investigating potential models of amotivation in schizophrenia. AB - BACKGROUND: Schizophrenia is a debilitating neurodevelopmental disorder affecting 1% of the global population with heterogeneous symptoms including positive, negative, and cognitive. While treatment for positive symptoms exists, none have been developed to treat negative symptoms. Animal models of schizophrenia are required to test targeted treatments and since patients exhibit reduced effort (breakpoints) for reward in a progressive ratio (PR) task, we examined the PR breakpoints of rats treated with the NMDA receptor antagonist phencyclidine or those reared in isolation - two common manipulations used to induce schizophrenia relevant behaviors in rodents. METHODS: In two cohorts, the PR breakpoint for a palatable food reward was examined in Long Evans rats after: 1) a repeated phencyclidine regimen; 2) A subchronic phencyclidine regimen followed by drug washout; and 3) post-weaning social isolation. RESULTS: Rats treated with repeated phencyclidine and those following washout from phencyclidine exhibited higher PR breakpoints than vehicle-treated rats. The breakpoint of isolation reared rats did not differ from those socially reared, despite abnormalities of these rats in other schizophrenia-relevant behaviors. CONCLUSION: Despite their common use for modeling other schizophrenia-relevant behaviors neither phencyclidine treatment nor isolation rearing recreated the motivational deficits observed in patients with schizophrenia, as measured by PR breakpoint. Other manipulations, and negative symptom-relevant behaviors, require investigation prior to testing putative therapeutics. PMID- 29175448 TI - In situ investigation of bismuth nanoparticles formation by transmission electron microscope. AB - Bismuth (Bi) nanoparticles are prepared by using NaBi(MoO4)2 nanosheets in the beam of electrons emitted by transmission electron microscope. The formation and growth of Bi nanoparticles are investigated in situ. The sizes of Bi nanoparticles are confined within the range of 6-10nm by controlling irradiation time. It is also observed that once the diameter of nanoparticles is larger than 10nm, the Bi particles are stable as a result of the immobility of large nanoparticles. In addition, some nanoparticles on the edges form nanorods, which are explained as the result of a coalescence process, if the irradiation period is longer than 10min. The in situ research on Bi nanoparticles facilitates in depth investigations of the physicochemical behavior and provides more potential applications in various fields such as sensors, catalysts and optical devices. PMID- 29175447 TI - Suppressive and enhancing effects of nicotine on food-seeking behavior. AB - The present study examined how systemic low doses of nicotine affect the microstructure of reinforced food-seeking behavior in rats. Rats were first given an acute saline or nicotine treatment (0.1-0.6mg/kg, with an inter-injection interval of at least 48h), and then a chronic saline or nicotine treatment (0.3mg/kg/day for 10 consecutive days). Immediately after each injection, rats were required to press a lever five times to obtain food that was available at unpredictable times (on average every 80s) with constant probability. Acute nicotine dose-dependently suppressed behavior prior to the delivery of the first reinforcer, but enhanced food-reinforced behavior afterwards. These effects were primarily observed in the time it took rats to initiate food-seeking behavior. Enhancing effects were also observed in the microstructure of food-seeking behavior, with lower nicotine doses (0.1-0.3mg/kg) increasing the rate at which response bouts were initiated, and higher doses (0.3-0.6mg/kg) increasing within bout response rates. A pre-feeding control suggests that changes in appetite alone cannot explain these effects. Over the course of chronic nicotine exposure, tolerance developed to the suppressive, but not to the enhancing effects of nicotine on food-seeking behavior. These results suggest that (a) lower doses of nicotine enhance the reward value of food and/or food-associated stimuli, (b) higher doses of nicotine enhance motoric activity, and (c) ostensive sensitization effects of nicotine on behavior partially reflect a tolerance to its transient suppressive motoric effects.

PMID- 29175450 TI - Crosstalk between mAChRM3 and beta2AR, via acetylcholine PI3/PKC/PBEP1/Raf-1 MEK1/2/ERK1/2 pathway activation, in human bronchial epithelial cells after long term cigarette smoke exposure. AB - BACKGROUND: Cigarette smoke extract (CSE) affects the expression of non-neuronal components of cholinergic system in bronchial epithelial cells and, as PEBP1/Raf mediated MAPK1/2 and ERK1/2 pathway, promotes inflammation and oxidative stress. AIMS: We studied whether Acetylcholine (ACh) is involved in the mechanism of crosstalk between mAChRM3 and beta2Adrenergic receptors (beta2AR) promoting, via PI3/PKC/PBEP1/Raf/MEK1/2/ERK1/2 activation, beta2AR desensitization, inflammation and, oxidative stress in a bronchial epithelial cell line (16HBE) after long-term exposure to cigarette smoke extract (LECSE). METHODS: We evaluated mAChRM3 and Choline Acetyltransferase (ChAT) expression, ACh production, PEBP1, ERk1/2, and beta2AR phosphorylation, as well as NOX-4, ROS production and IL-8 release in 16HBE after LECSE. The inhibitory activity of Hemicholinium (HCh-3) (a potent choline uptake blocker), LY294002 (a highly selective inhibitor of PI3 kinase), Tiotropium (Spiriva(r)) (anticholinergic drug) and Olodaterol (beta2AR agonist), were tested in 16HBE after LECSE. RESULTS: mAChRM3, ChAT, ACh activity, pPEBP1, pbeta2AR, pERK1/2, ROS, NOX-4 and IL-8 increased after LECSE in 16HBE LECSE compared to untreated cells. HCh-3 and LY294002 (alone or in combination) as well as Tiotropium (Spiriva(r)) or Olodaterol (alone or in combination) all reduced the levels of pPEBP1, pbeta2AR, pERK1/2, ROS, NOX-4, and IL-8 in 16HBE LECSE compared to untreated cells. CONCLUSIONS: LECSE promotes ACh production which enhances PI3/PKC/PEBP1/Raf-ERK1/2 pathway activation, heterologous beta2AR desensitization, as well as release of inflammatory and oxidative mediators in bronchial epithelial cells. The use of anticholinergic drugs and long-acting beta2-agonists, alone or in combination may be dampen these inflammatory mechanisms when used in combination in some epithelial cell types. PMID- 29175451 TI - Short-term Clinical Efficacy of Electric Pudendal Nerve Stimulation on Neurogenic Lower Urinary Tract Disease: A Pilot Research. AB - OBJECTIVE: To compare the short-term efficacy of electrical pudendal nerve stimulation (EPNS) vs anogenital electrical stimulation (AES) for neurogenic lower urinary tract disease. PATIENTS AND METHODS: Sixty eligible participants were randomized at a ratio of 2:1 to the test group of 40 patients and the control group of 20. The test group was treated with EPNS and the control group was treated with AES. After 12 sessions of treatment, therapeutic effects were evaluated based on self-assessed questionnaire scores. All patients with a residual urine volume >50 mL were also assessed by the post-treatment residual urine volume. RESULTS: At the end of treatment, the median symptom score and the quality of life score were 11 (range 3-23) and 4.26 (range 1.00-5.81) in the test group, and the median post-treatment residual urine volume was 46 (range 0-223) mL. By contrast, the median severity of symptoms and quality of life scores were 15 (range 8-33) and 3.84 (range 0.89-5.84) in the control group, and the median post-treatment residual urine volume was 105 (range 28-340) mL. Significant differences between the test group and the control group could be observed in the post-treatment symptom score, the quality of life score, and the residual urine volume (with P = .005, P <.001, P = .02, respectively). CONCLUSION: Compared with AES, EPNS is more effective in treating neurogenic lower urinary tract disease in the short term. PMID- 29175452 TI - Changes in expression of cytokines in polyhexamethylene guanidine-induced lung fibrosis in mice: Comparison of bleomycin-induced lung fibrosis. AB - Inhalation of polyhexamethylene guanidine (PHMG) causes irreversible pulmonary injury, such as pulmonary fibrosis. However, the mechanism underlying PHMG induced lung injury is unclear. In this study, we compared the difference in time dependent lung injury between PHMG- and bleomycin (BLM)-treated mice and determined cytokines involved in inducing lung injury by performing cytokine antibody array analysis. Mice were treated once with 1.8mg/kg BLM or 1.2mg/kg PHMG through intratracheal instillation and were sacrificed on days 7 and 28. Bronchoalveolar lavage fluid (BALF) analysis showed that the number of neutrophils was significantly higher in PHMG-treated mice than in BLM-treated mice on day 7. Histopathological analysis showed inflammatory cell infiltration and fibrosis mainly in the terminal bronchioles and alveoli in the lungs of PHMG- and BLM-treated mice. However, continuous macrophage infiltration in the alveolar space and bronchioloalveolar epithelial hyperplasia (BEH) were only observed in PHMG-treated mice. Cytokine antibody array analysis showed that 15 and eight cytokines were upregulated in PHMG- and BLM-treated mice, respectively, on day 7. On day 28, 13 and five cytokines were upregulated in PHMG and BLM-treated mice, respectively. In addition, the expressed cytokines between days 7 and 28 in BLM treated mice were clearly different, but were similar in PHMG-treated mice. Consequently, between PHMG- and BLM-treated mice, we observed differences in the expression patterns and types of cytokines. These differences are considered to be a result of the inflammatory processes induced by both substances, which may mainly involve macrophage infiltration. Therefore, continuous induction of the inflammatory response by PHMG may play an important role in the development of pulmonary fibrosis. PMID- 29175453 TI - Activation of PPARalpha decreases bile acids in livers of female mice while maintaining bile flow and biliary bile acid excretion. AB - Fibrates are hypolipidemic drugs that act as activators of peroxisome proliferator-activated receptor alpha (PPARalpha). In both humans and rodents, females were reported to be less responsive to fibrates than males. Previous studies on fibrates and PPARalpha usually involved male mice, but little has been done in females. The present study aimed to provide the first comprehensive analysis of the effects of clofibrate (CLOF) and PPARalpha on bile acid (BA) homeostasis in female mice. Study in WT male mice showed that a 4-day CLOF treatment increased liver weight, bile flow, and biliary BA excretion, but decreased total BAs in both serum and liver. In contrast, WT female mice were less susceptible to these CLOF-mediated responses observed in males. In WT female mice, CLOF decreased total BAs in the liver, but had little effect on the mRNAs of hepatic BA-related genes. Next, a comparative analysis between WT and PPARalpha-null female mice showed that lack of PPARalpha in female mice decreased total BAs in serum, but had little effect on total BAs in liver or bile. However, lack of PPARalpha in female mice increased mRNAs of BA synthetic enzymes (Cyp7a1, Cyp8b1, Cyp27a1, and Cyp7b1) and transporters (Ntcp, Oatp1a1, Oatp1b2, and Mrp3). Furthermore, the increase of Cyp7a1 in PPARalpha-null female mice was associated with an increase in liver Fxr-Shp-Lrh-1 signaling. In conclusion, female mice are resistant to CLOF-mediated effects on BA metabolism observed in males, which could be attributed to PPARalpha-mediated suppression in females on genes involved in BA synthesis and transport. PMID- 29175455 TI - Anxiolytic- and antidepressant-like effects of Silymarin compared to diazepam and fluoxetine in a mouse model of mild traumatic brain injury. AB - Clinical and experimental studies have shown that mild traumatic brain injury (mTBI) is associated with increased anxiety- and depression-related behaviors and inflammation in the brain. Unfortunately, there are no specific therapies for long-term behavioral consequences of mTBI. This study set out to determine whether silymarin treatment compared to diazepam (DZP) and fluoxetine (FLX) can reduce neuroinflammation, anxiety- and depression-like behaviors after mTBI induction in mice. We used open field, elevated plus maze, light-dark box, zero maze, sucrose preference, forced swim, and tail suspension tests to assess anxiety and depression-like behaviors in mTBI-induced mice. The levels of tumor necrosis factor (TNF)-alpha protein, a marker of inflammation, in the prefrontal cortex and hippocampus was also measured. This study identified that the long term treatment with DZP, FLX or SIL results in decreased anxiety and depression like behaviors in mTBI-induced mice. The results also showed that these drugs reduced TNF-alpha levels in the prefrontal cortex and hippocampus. In addition, there were no significant differences between the effects of SIL and DZP or SIL and FLX on behavioral and cytokine levels in mTBI-induced mice. Our findings support the idea that mTBI could be a risk factor for anxiety- and depression related disorders and neuroinflammation in the brain. Taken together, this study demonstrates that DZP, FLX or SIL can significantly reduce anxiety- and depression-like symptoms, and neuroinflammation after mTBI induction in mice.

AB - Methylation at cytosine (5mC) is a fundamental epigenetic DNA modification recently associated with iAs-mediated carcinogenesis. In contrast, the role of 5 hydroxymethylcytosine (5hmC), the oxidation product of 5mC in iAs-mediated carcinogenesis is unknown. Here we assess the hydroxymethylome in iAs-transformed cells, showing that dynamic modulation of hydroxymethylated DNA is associated with specific transcriptional networks. Moreover, this pathologic iAs-mediated carcinogenesis is characterized by a shift toward a higher hydroxymethylation pattern genome-wide. At specific promoters, hydroxymethylation correlated with increased gene expression. Furthermore, this increase in hydroxymethylation occurs concurrently with an upregulation of ten-eleven translocation (TET) enzymes that oxidize 5-methylcytosine (5mC) in DNA. To gain an understanding into how iAs might impact TET expression, we found that iAs inhibits the binding of CTCF at the proximal, weak CTCF binding sites of the TET1 and TET2 gene promoters and enhances CTCF binding at the stronger distal binding site. Further analyses suggest that this distal site acts as an enhancer, thus high CTCF occupancy at the enhancer region of TET1 and TET2 possibly drives their high expression in iAs transformed cells. These results have major implications in understanding the impact of differential CTCF binding, genome architecture and its consequences in iAs-mediated pathogenesis.

AB - A swift increase has been observed in the number of individuals with metabolic syndrome worldwide. A number of natural compounds have been identified towards combating metabolic syndrome. Adding to this premise, here we report the pleiotropic activities of Ecliptal (EC); a natural compound isolated from the herb Eclipta alba. Administration of EC was shown to have prominent anti adipogenic effects in 3T3-L1 and hMSC derived adipocytes. It was shown to activate Wnt-pathway and alter AKT signaling. Additionally, it caused cell cycle arrest and inhibited mitotic clonal expansion. EC treatment augmented mitochondrial biogenesis as well as function as estimated by expression of PGC1alpha, UCP-1, mitochondrial complexes and estimation of oxygen consumption rate. EC also reduced LPS-induced inflammation and tunicamycin induced ER stress. Further, EC enhanced insulin sensitivity by increasing AKT phosphorylation, inhibiting PKCalpha/betaII phosphorylation and reducing leptin/adiponectin ratio. Finally, EC administration in Syrian golden hamsters was shown to have potent anti-dyslipidemic effects. Cumulatively, encompassing pleiotropic activities of EC, it could prove to be a potential drug candidate against obesity, insulin resistance and related metabolic syndrome. PMID- 29175457 TI - Liposomal nanohybrid cerasomes targeted to PD-L1 enable dual-modality imaging and improve antitumor treatments. AB - Programmed death ligand-1 (PD-L1) is a central element in cancer therapies targeting immune checkpoints, and its expression is an important predictor of the therapeutic response. With recent approvals of therapeutic antibodies against PD L1 and PD-1, noninvasive detection methods are now urgently needed to quantify PD L1 expression in tumors and to evaluate the response to immune therapies. However, only few such methods are available. Thus, we fabricated nanohybrid liposomal cerasome nanoparticles loaded with the chemotherapeutic drug paclitaxel, and evaluated their value as a theranostic agent. The particles are also decorated with PD-L1 antibody to enable specific targeting, and are dual labeled to enable near-infrared fluorescence (NIRF) and magnetic resonance imaging (MRI) in vivo. Results showed that in vivo NIRF and MRI imaging following intravenous injection of cerasomes revealed a strong positive contrast for tumors, indicating long-lived enhancement of relevant signals. Moreover, the cerasomes were more effective against tumors and metastasis in comparison to simultaneous but nontargeted delivery of PD-L1 antibody and paclitaxel. Taken together, the data indicate that targeted, dual-labeled cerasomes are good theranostic agents for MRI/NIRF dual-mode detection and treatment of solid tumors in situ. PMID- 29175458 TI - TM4SF1 regulates apoptosis, cell cycle and ROS metabolism via the PPARgamma-SIRT1 feedback loop in human bladder cancer cells. AB - Transmembrane-4-L-Six-Family-1 (TM4SF1) is a member of the L6 family and functions as a signal transducer to regulate cell development, growth and motility. Here we show that TM4SF1 is strongly upregulated in human muscle invasive bladder cancer (MIBC) tissues, corroborating the bioinformatical results of transcriptome analysis. Moreover, tissue microarray (TMA) shows significant correlations (p < 0.05) between high expression of TM4SF1 and T stage, TNM stage, lymph node metastasis status and survival rate of MIBC patients, indicating a positive association between TM4SF1 expression and poorer prognosis. Furthermore, in vitro and in vivo studies indicate that the proliferation of human bladder cancer (BCa) cells is significantly suppressed by knockdown of TM4SF1 (p < 0.05). Functionally, the reduction of TM4SF1 could induce cell cycle arrest and apoptosis possibly via the upregulation of reactive oxygen species (ROS) in BCa cells. In addition, these observations could be recovered by treatment with GW9662 (antagonist of PPARgamma) and resveratrol (activator of SIRT1). Taken together, our results suggest that high expression of TM4SF1 predicts poor prognosis of MIBC. PMID- 29175459 TI - PPP2R5A: A multirole protein phosphatase subunit in regulating cancer development. AB - Protein phosphatase 2, regulatory subunit B (B56), alpha isoform (PPP2R5A) is one of the regulatory subunits of the protein phosphatase 2A (PP2A), which is a major member of protein serine/threonine phosphatases in cells. PPP2R5A can regulate the cellular location, substrate specification and protein phosphatase function of PP2A, through which PPP2R5A plays an important role in many cellular activities. It has been reported that PPP2R5A relates with many diseases including some kinds of cancers, but the related mechanisms have a lot remaining to be discovered or demonstrated. This review arms to summarize PPP2R5A and its relationships with the occurrence and progression of tumors, helping us to further understand its significance in the prevention, early diagnosis, targeted therapy and prognosis improvement of tumors. PMID- 29175460 TI - Bad phosphorylation as a target of inhibition in oncology. AB - Bcl-2 agonist of cell death (BAD) is a BH3-only member of the Bcl-2 family which possesses important regulatory function in apoptosis. BAD has also been shown to possess many non-apoptotic functions closely linked to cancer including regulation of glycolysis, autophagy, cell cycle progression and immune system development. Interestingly, BAD can be either pro-apoptotic or pro-survival depending on the phosphorylation state of three specific serine residues (human S75, S99 and S118). Expression of BAD and BAD phosphorylation patterns have been shown to influence tumor initiation and progression and play a predictive role in disease prognosis, drug response and chemosensitivity in various cancers. This review aims to summarize the current evidence on the functional role of BAD phosphorylation in human cancer and evaluate the potential utility of modulating BAD phosphorylation in cancer. PMID- 29175461 TI - The future of mesenchymal stem cell-based therapeutic approaches for cancer - From cells to ghosts. AB - Mesenchymal stem cells (MSCs) are multipotent stromal cells which can differentiate into a variety of cell types including osteoblasts, adipocytes and chondrocytes. They are normally resident in adipose tissue, bone marrow and the umbilical cord, but can also be found in other tissues and are known to be recruited to sites of wound healing as well as growing tumours. The therapeutic potential of MSCs has been explored in a number of phase I/II and III clinical trials, of which several were targeted against graft-versus-host disease and to support engraftment of haematopoietic stem cells (HSCs), but currently only very few in the oncology field. There are now three clinical trials either ongoing or recruiting patients that use MSCs to treat tumour disease. In these, MSCs target gastrointestinal, lung and ovarian cancer, respectively. The first study uses MSCs loaded with a HSV-TK expression construct under the control of the CCL5 promoter, and has recently reported successful completion of Phase I/II. While no adverse side effects were seen during this study, no outcomes with respect to therapeutic benefits have been published. The other clinical trials targeting lung and ovarian cancer will be using MSCs expressing cytokines as therapeutic payload. Despite these encouraging early steps towards their clinical use, many questions are still unanswered regarding the biology of MSCs in normal and pathophysiological settings. In this review, in addition to summarising the current state of MSC-based therapeutic approaches for cancer, we will describe the remaining questions, obstacles and risks, as well as novel developments such as MSC-derived nanoghosts. PMID- 29175462 TI - Metabolic adaptation of macrophages in chronic diseases. AB - In response to physiological and pathological stimuli, macrophages are able to adapt and shape their phenotype, giving rise to a broad range of functional activation that is unique in different organs and different pathologies. The plasticity of macrophages is accomplished not only by di stinct signalling pathways and transcriptional profiles but also by specific engagement of preferential metabolic pathways. In the last decade, macrophage metabolism became the object of multiple studies showing that, by altering nutrient availability or by blocking specific metabolic pathway it is possible to skew macrophage phenotype and alter their effector functions. This field of research opens new therapeutic windows for the cure of several disease. Here we will give an overview of the current knowledge of macrophage metabolism in cancer, atherosclerosis and obesity and how this knowledge could be translated in therapeutic opportunities. PMID- 29175463 TI - Increasing methamphetamine injection among non-MSM who inject drugs in King County, Washington. AB - BACKGROUND: In King County, Washington, the HIV prevalence among men who have sex with men (MSM) who inject methamphetamine is high, while it is low among other people who inject drugs (PWID). Local drug problem indicators suggest that methamphetamine use is increasing. The extent to which this increase affects MSM and non-MSM, and whether MSM and non-MSM networks are connected through injection equipment sharing, is unknown. METHODS: We used data from two serial cross sectional surveys of PWID including five biannual surveys of Public Health Seattle and King County Needle and Syringe Exchange Program clients (NSEP, N=2135, 2009-2017) and three National HIV Behavioral Surveillance IDU surveys (NHBS, N=1709, 2009-2015). RESULTS: The proportion of non-MSM PWID reporting any recent methamphetamine injection increased significantly from approximately 20% in 2009 to 65% in 2017. Most of this increase was attributable to injecting methamphetamine in combination with heroin (goofballs). PWID who injected goofballs were more likely to be younger, homeless or unstably housed, report daily injection, and self-report an opioid overdose in the past year than other PWID. The majority of PWID who injected methamphetamine reported sharing any injection equipment. Among these PWID, 43% of MSM had last shared injection equipment with a non-MSM. Eight percent of non-MSM men and 15% of women had last shared equipment with an MSM. CONCLUSIONS: Given non-trivial rates of sharing injection equipment with methamphetamine-using MSM, a population with an HIV prevalence of 40%, non-MSM who inject methamphetamine could be an emerging population at risk for acquiring HIV. PMID- 29175464 TI - Salience network coupling is linked to both tobacco smoking and symptoms of attention deficit hyperactivity disorder (ADHD). AB - INTRODUCTION: Attention deficit hyperactivity disorder (ADHD) symptoms, even those below diagnostic threshold, enhance the likelihood of nicotine dependence, suggesting a neurobiological link between disorders. Of particular interest is the salience network (SN), which mediates attention to salient internal/external stimuli to guide behavior and is anchored by the dorsal anterior cingulate cortex (dACC) and bilateral anterior insula (AI). Disrupted interactions between the SN and the default mode (DMN) and central executive networks (CEN) have been noted in both ADHD and nicotine dependence. Further, enhanced intra-SN coupling between the dACC-AI influences aspects of nicotine dependence such as reactivity to smoking cues. METHODS: To identify links between SN functional connectivity and ADHD symptoms in nicotine dependence, we compared 21 nicotine dependent individuals with 17 non-smokers on ADHD symptoms as measured by the ADHD self report scale (ASRS) and resting state intra and inter-SN functional connectivity. RESULTS: Relative to healthy controls, nicotine dependent individuals had significantly higher ASRS scores and greater dACC-AI coupling. No group differences were noted on inter-SN network coupling. A significant association was found between ASRS and dACC-AI coupling both in the entire cohort and specifically when evaluating nicotine dependent individuals alone. CONCLUSIONS: The greater ASRS scores in nicotine dependent individuals is in line with existent literature and the stronger dACC-AI coupling in smokers further supports the role of this network in nicotine dependence. The significant association between dACC-AI coupling and ASRS suggests that intra-SN coupling strength may impact neurocognitive functioning associated with both ADHD symptoms and nicotine dependence. PMID- 29175465 TI - Effect of photodynamic and laser therapy in the treatment of peri-implant mucositis: A systematic review. AB - BACKGROUND: The present study systematically reviewed the literature to investigate the effect of photodynamic therapy (PDT) or laser therapy (LT) in the management of peri-implant mucositis (p-iM). METHODS: The electronic databases were searched until October 2017. Outcome measures were bleeding on probing (BOP), plaque index (PI), or probing depth (PD). The addressed PICO question was: "Is PDT and LT effective in the management of p-iM?" RESULTS: A total of five studies included in the qualitative analysis, two of which had a low risk of bias. Three studies used PDT while two studies used LT. All studies reported a significant improvement in clinical peri-implant inflammatory parameters in p-iM. For PDT, one study demonstrated a significant reduction for PDT group as compared to manual debridement (MD), while one study indicated comparable outcomes when tested with probiotics at follow-up. One study used PDT alone and indicated significant improvements in peri-implant parameters at follow-up. However, in the studies using LT, one study demonstrated a significant improvement in peri implant parameters as compared to scaling and root planing alone, while other study indicated comparable outcomes when compared with manual debridement/chlorhexidine group at follow-up. CONCLUSION: This systematic review demonstrated inconclusive findings to show the effect of PDT or LT in the management of p-iM due to methodological heterogeneity such as non-standard control groups, laser parameters and short follow-up period. The results of this review should be considered preliminary and further, more robust, well-designed studies with long-term follow up and standardized comparators with laser parameters are warranted. PMID- 29175466 TI - Photodynamic therapy for treatment of oral mucositis: Pilot study with pediatric patients undergoing chemotherapy. AB - BACKGROUND: Oral mucositis has become a major dose-limiting toxicity of antineoplastic treatment. AIM: The aim of this study was to evaluate the effect of photodynamic therapy (PDT) and low level laser therapy (LLLT) on the treatment of chemotherapy-induced mucositis in pediatric patients. METHODS: An open, controlled, and blind, randomized clinical trial was conducted with 29 patients, from 10 months to 18 years old, who were divided into two groups. Group A was submitted to photodynamic therapy (0.01% Methylene Blue and red laser, lambda660 nm) with 3J energy per point; and Group B submitted to low level laser therapy (lambda660 nm) with 1J energy per point. The results were evaluated by using the WHO and ChIMES mucositis scales. The Chi-square, Exact Fisher, Student's-t and Mann-Whitney tests, and the mixed linear regression model were used for comparison between the groups, with the maximum error admitted of 5%. RESULTS: There was no difference between the groups as regards the number of sessions necessary for clinical cure of the oral lesions (p = 0.954) or reduction in pain reported by the patients (p = 0.258; p = 0.486). Within each group, however, there was significant reduction in pain (p = 0.032; p = 0.003). The number needed to treat (NNT) was 4.75. CONCLUSIONS: PDT or LLLT could be used for treatment of oral mucositis in children/young patients. Each were well tolerated and presented satisfactory results in reducing pain associated with the lesion. PMID- 29175467 TI - Synthesis, in vitro and in vivo evaluation of 18F-fluoronorimatinib as radiotracer for Imatinib-sensitive gastrointestinal stromal tumors. AB - INTRODUCTION: Gastrointestinal stromal tumors (GIST) have a wide range of mutations, but can mostly be treated with Imatinib, until eventually resistance towards this tyrosine kinase inhibitor is acquired. Early and non-invasive determination of the sensitivity of the tumor and its metastases towards Imatinib by positron emission tomography (PET) would be beneficial for therapy planning and monitoring. METHODS: We developed a synthesis strategy towards the precursor molecule, performed the 18F-synthesis and in the following evaluated the radioligand in vitro regarding its lipophilicity, stability and biological activity (KIT binding properties) as well as its in vivo properties in GIST tumor bearing mice. RESULTS: [18F]fluoronorimatinib could be obtained in an overall radiochemical yield of 22.2+/-3.3% within 90min. The radioligand showed high GIST cell uptake and was able to distinguish between Imatinib-sensitive and resistant tumor cell lines (GIST-T1, GIST882, GIST430) in vitro. Further biological evaluations of the ligand towards 9 different GIST-relevant KIT mutations showed comparable binding affinities compared to the structural lead Norimatinib (65nM vs. 53nM for wt-KIT). The in vivo evaluation of the newly developed radioligand showed tumor-to-background-ratios comparable to previously described, similar radiotracers. CONCLUSIONS: Thus, [18F]fluoronorimatinib is able to distinguish between Imatinib-resistant and sensitive KIT mutations. Although no improvement of in vivo tumor-to-background ratios could be achieved compared to formerly described radioligands, the hepatic uptake could be considerably reduced, being advantageous for the imaging of GIST. Advances in knowledge and implications for patient care: We were able to show that it is possible to significantly reduce the unfavorably high hepatic uptake of small-molecule radioligands applicable for GIST PET imaging. This work can thus be the basis for further work intending to develop a PET-radioligand for Imatinib-dependent GIST imaging.

PMID- 29175469 TI - Histogram based analysis of lung perfusion of children after congenital diaphragmatic hernia repair. AB - OBJECTIVES: To investigate a histogram based approach to characterize the distribution of perfusion in the whole left and right lung by descriptive statistics and to show how histograms could be used to visually explore perfusion defects in two year old children after Congenital Diaphragmatic Hernia (CDH) repair. METHODS: 28 children (age of 24.2+/-1.7months; all left sided hernia; 9 after extracorporeal membrane oxygenation therapy) underwent quantitative DCE-MRI of the lung. Segmentations of left and right lung were manually drawn to mask the calculated pulmonary blood flow maps and then to derive histograms for each lung side. Individual and group wise analysis of histograms of left and right lung was performed. RESULTS: Ipsilateral and contralateral lung show significant difference in shape and descriptive statistics derived from the histogram (Wilcoxon signed-rank test, p<0.05) on group wise and individual level. Subgroup analysis (patients with vs without ECMO therapy) showed no significant differences using histogram derived parameters. CONCLUSIONS: Histogram analysis can be a valuable tool to characterize and visualize whole lung perfusion of children after CDH repair. It allows for several possibilities to analyze the data, either describing the perfusion differences between the right and left lung but also to explore and visualize localized perfusion patterns in the 3D lung volume. Subgroup analysis will be possible given sufficient sample sizes. PMID- 29175470 TI - A comparison of readout segmented EPI and interleaved EPI in high-resolution diffusion weighted imaging. AB - PURPOSE: To provide a comprehensive understanding of multi-shot EPI diffusion imaging methods by comparing Readout segmented EPI (RS-EPI) and interleaved EPI (iEPI). MATERIALS AND METHODS: RS-EPI and iEPI were compared on the same 3T scanner. A 2D navigator was used for both RS-EPI and iEPI for phase correction. Signal to noise ratio (SNR), fractional anisotropy (FA) and distortion level were compared using phantom data. Distortion reduction capability and scan efficiency were compared with different protocols with simulations. In addition, distortion reduction capability and diffusion tensor imaging performance were compared using in vivo data. RESULTS: Our phantom data showed that the mean SNRs were 50.5, 86.6 and 45.4 for RS-EPI using GRAPPA=3, fully sampled iEPI and iEPI using GRAPPA=2 respectively. The mean FA values were 0.08, 0.05 and 0.09 for RS-EPI using GRAPPA=3, fully sampled iEPI and iEPI using GRAPPA=2 respectively. The distortion levels were 1.34mm, 1.29mm and 0.61mm for RS-EPI using GRAPPA=3, fully sampled iEPI and iEPI using GRAPPA=2 respectively. The effective echo spacing could be reduced by increasing the number of shots for both methods but more prominent for iEPI. The scan time was approximately proportional to the number of shots for both methods and RS-EPI showed a shorter scan time. Our in vivo data for distortion comparison showed consistent results with the effective echo spacing study. The mean difference of the FA and MD values between the high resolution sequences and SS-EPI was all within 7%. CONCLUSION: For high resolution diffusion imaging, iEPI has more potential in distortion reduction than RS-EPI when increasing the number of shots. RS-EPI can achieve a reasonable SNR with a shorter scan time than iEPI. RS-EPI and iEPI have similar performance in FA and MD quantifications as well as showing structure details when using eleven shots for in vivo diffusion tensor imaging. PMID- 29175471 TI - Deletion of mstna and mstnb impairs the immune system and affects growth performance in zebrafish. AB - Myostatin (Mstn) is a negative regulator of muscle development in vertebrates. Although its function in muscle growth has been well studied in mammals and fish, it remains unclear whether or how mstn functions in the immune system. In this study, mstna-/- and mstnb-/- homozygous zebrafish were firstly generated using CRISPR/Cas9 (Clustered regularly interspaced short palindromic repeats/CRISPR associated protein 9). Deletion of mstnb but not mstna enhanced growth performance. Although survival rates under normal conditions were slightly decreased in both strains, mortality after dexamethasone-induced stress was increased by ~30%. Furthermore, transcriptional levels of several critical immune related genes were decreased, and the ability to withstand exposure to pathogenic E. tarda was decreased, compared with that of controls. In mstnb-/- but not mstna /- zebrafish, expression of NF-kappaB subunits and several pro-inflammatory cytokines failed to respond to E. tarda exposure except nfkb1, c-rel and tnfalpha. Taken together, these results indicate that mstnb but not mstna plays a key role in zebrafish muscle growth. While each paralogue contributes to the response to bacterial insult, mstnb affects the immune system through activation of the NF-kappaB pathway, and mstna is likely to act upstream of NF-kappaB at some as yet unidentified target. PMID- 29175472 TI - Vaccination and immune responses of European sea bass (Dicentrarchus labrax L.) against betanodavirus. AB - This review summarizes the available knowledge on the immune defences of European sea bass against antigenic preparations derived from the viral encephalopathy and retinopathy virus (betanodavirus), which represents a major threat to the health of this fish species. The nodavirus is widely present and differentiates into several strains that infect invertebrates (in insects, alphanodavirus) and teleost fish, and thus may represent a great problem for farmed fish species. Many efforts have been directed to discovering new immunizations to induce protection in sea bass, especially at young stages, and these efforts have included employing diverse betanodavirus strains, antigen preparation, vaccination routes, and the addition of adjuvants and/or immunostimulants. The obtained results showed that inactivated preparations of betanodavirus that were administered intraperitoneally may induce both immune recognition and protection. Attempts at performing mucosal immunization by immersion and/or oral administration, which is a vaccination route that is highly preferred for sea bass, have shown intriguing results, and more studies are necessary for its improvement. Overall, the objective of identifying a reliable vaccine that also cross-protects against different genotypes or reassortant viruses for use in European sea bass against betanodavirus appears to be an attainable goal in the near future. PMID- 29175473 TI - Mechanisms underlying the heterogeneity of myelodysplastic syndromes. AB - Myelodysplastic syndromes (MDS) are hematopoietic stem cell (HSC) disorders in which recurrent chromosome abnormalities and gene mutations define a clonal hematopoiesis. The MDS-initiating cell is a rare HSC which transmits the genetic abnormalities to its myeloid and lymphoid progeny. The heterogeneity of MDS phenotypes could be linked to the diversity of genetic events involving epigenetic regulators, chromatin modifiers, splicing factors, transcription factors and signaling adaptors, the various combinations and order of mutations in cooperating genes, and the variegation of clonal hematopoietic hierarchy. Usually, epigenetic and splicing gene mutations occur first. A combination of one epigenetic event with a splicing gene alteration is frequent. The HSC compartment is invaded by a dominant and few minor clones organized linearly or with a branched architecture. The dominant clone containing the first initiating mutations produces myeloid and lymphoid lineages in transplanted immune-deficient mice. The mutations confer a selective advantage to myeloid progenitors at the expense of lymphoid progenitors. In the context of differentiation, one mutation may favor the amplification of granulo-monocytic progenitor, which drives the transformation into acute myeloid leukemia. Understanding the hierarchy of mutations provides insights on the mechanism of transformation. Investigation of mutation pattern and distribution along the hematopoietic tree may influence the therapeutic decision for targeted therapy. PMID- 29175474 TI - Enhanced H3K4me3 modifications are involved in the transactivation of DNA damage responsive genes in workers exposed to low-level benzene. AB - In this study, we explore whether altered global histone modifications respond to low-level benzene exposure as well as their association with the hematotoxicity. We recruited 147 low-level benzene-exposed workers and 122 control workers from a petrochemical factory in Maoming City, Guangdong Province, China. The internal exposure marker level, urinary S-phenylmercapturic acid (SPMA), in benzene exposed workers was 1.81-fold higher than that of the controls (P < 0.001). ELISA method was established to examine the specific histone modifications in human peripheral blood lymphocytes (PBLCs) of workers. A decrease in the counts of white blood cells (WBC), neutrophils, lymphocytes, and monocytes appeared in the benzene-exposed group (all P < 0.05) compared to the control group. Global trimethylated histone 3 lysine 4 (H3K4me3) modification was enhanced in the benzene-exposed group (P < 0.05) and was positively associated with the concentration of urinary SPMA (beta = 0.103, P = 0.045) and the extent of DNA damage (% Tail DNA: beta = 0.181, P = 0.022), but was negatively associated with the leukocyte count (WBC: beta = -0.038, P = 0.023). The in vitro study revealed that H3K4me3 mark was enriched in the promoters of several DNA damage responsive (DDR) genes including CRY1, ERCC2, and TP53 in primary human lymphocytes treated with hydroquinone. Particularly, H3K4me3 modification was positively correlated with the expression of CRY1 in the PBLCs of benzene-exposed workers. These observations indicate that H3K4me3 modification might mediate the transcriptional regulation of DDR genes in response to low-dose benzene exposure. PMID- 29175475 TI - Elevated ozone affects C, N and P ecological stoichiometry and nutrient resorption of two poplar clones. AB - The effects of elevated ozone on C (carbon), N (nitrogen) and P (phosphorus) ecological stoichiometry and nutrient resorption in different organs including leaves, stems and roots were investigated in poplar clones 546 (P. deltoides cv. '55/56' * P. deltoides cv. 'Imperial') and 107 (P. euramericana cv. '74/76') with a different sensitivity to ozone. Plants were exposed to two ozone treatments, NF (non-filtered ambient air) and NF60 (NF with targeted ozone addition of 60 ppb), for 96 days in open top chambers (OTCs). Significant ozone effects on most variables of C, N and P ecological stoichiometry were found except for the C concentration and the N/P in different organs. Elevated ozone increased both N and P concentrations of individual organs while for C/N and C/P ratios a reduction was observed. On these variables, ozone had a greater effect for clone 546 than for clone 107. N concentrations of different leaf positions ranked in the order upper > middle > lower, showing that N was transferred from the lower senescent leaves to the upper ones. This was also indicative of N resorption processes, which increased under elevated ozone. N resorption of clone 546 was 4 times larger than that of clone 107 under ambient air (NF). However, elevated ozone (NF60) had no significant effect on P resorption for both poplar clones, suggesting that their growth was only limited by N, while available P in the soil was enough to sustain growth. Understanding ecological stoichiometric responses under ozone stress is crucial to predict future effects on ecological processes and biogeochemical cycles. PMID- 29175476 TI - Source apportionment of aerosol particles at a European air pollution hot spot using particle number size distributions and chemical composition. AB - Ostrava in the Moravian-Silesian region (Czech Republic) is a European air pollution hot spot for airborne particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), and ultrafine particles (UFPs). Air pollution source apportionment is essential for implementation of successful abatement strategies. UFPs or nanoparticles of diameter <100 nm exhibit the highest deposition efficiency in human lungs. To permit apportionment of PM sources at the hot-spot including nanoparticles, Positive Matrix Factorization (PMF) was applied to highly time resolved particle number size distributions (NSD, 14 nm-10 MUm) and PM0.09-1.15 chemical composition. Diurnal patterns, meteorological variables, gaseous pollutants, organic markers, and associations between the NSD factors and chemical composition factors were used to identify the pollution sources. The PMF on the NSD reveals two factors in the ultrafine size range: industrial UFPs (28%, number mode diameter - NMD 45 nm), industrial/fresh road traffic nanoparticles (26%, NMD 26 nm); three factors in the accumulation size range: urban background (24%, NMD 93 nm), coal burning (14%, volume mode diameter - VMD 0.5 MUm), regional pollution (3%, VMD 0.8 MUm) and one factor in the coarse size range: industrial coarse particles/road dust (2%, VMD 5 MUm). The PMF analysis of PM0.09 1.15 revealed four factors: SIA/CC/BB (52%), road dust (18%), sinter/steel (16%), iron production (16%). The factors in the ultrafine size range resolved with NSD have a positive correlation with sinter/steel production and iron production factors resolved with chemical composition. Coal combustion factor resolved with NSD has moderate correlation with SIA/CC/BB factor. The organic markers homohopanes correlate with coal combustion and the levoglucosan correlates with urban background. The PMF applications to NSD and chemical composition datasets are complementary. PAHs in PM1 were found to be associated with coal combustion factor. PMID- 29175477 TI - Surface O3 photochemistry over the South China Sea: Application of a near explicit chemical mechanism box model. AB - A systematic field measurement was conducted at an island site (Wanshan Island, WSI) over the South China Sea (SCS) in autumn 2013. It was observed that mixing ratios of O3 and its precursors (such as volatile organic compounds (VOCs), nitrogen oxides (NOx = NO + NO2) and carbon monoxide (CO)) showed significant differences on non-episode days and episode days. Additional knowledge was gained when a photochemical box model incorporating the Master Chemical Mechanism (PBM MCM) was applied to further investigate the differences/similarities of O3 photochemistry between non-episode and episode days, in terms of O3-precursor relationship, atmospheric photochemical reactivity and O3 production. The simulation results revealed that, from non-O3 episode days to episode days, 1) O3 production changed from both VOC and NOx-limited (transition regime) to VOC limited; 2) OH radicals increased and photochemical reaction cycling processes accelerated; and 3) both O3 production and destruction rates increased significantly, resulting in an elevated net O3 production over the SCS. The findings indicate the complexity of O3 pollution over the SCS. PMID- 29175478 TI - Qualitative assessment to determine internal and external factors influencing the origin of styrene oligomers pollution by polystyrene plastic in coastal marine environments. AB - The objective of this study is to investigate the qualitative contribution of internal and external factors of the area contaminated by polystyrene (PS) in coastal marine environments. This study is based on the extensive results of monitoring the styrene oligomers (SOs) present in sand and seawater samples along various coastlines of the Pacific Ocean. Here, anthropogenic SOs is derived from PS during manufacture and use, and can provide clues about the origin of SOs by PS pollution. The monitoring results showed that, if the concentration of SOs in water is higher than those concentrations in beach sand, this area could be affected by PS plastic caused by an external factor. On the other hand, if the concentration of SOs is higher in the beach sand, the region can be mainly influenced by PS plastic derived from its own area. Unlike the case of an external factor, in this case (internal influence), it is possible to take policy measures of the area itself for the PS plastic problem. Thus, this study is motivated by the need of policy measures to establish a specific alternative to the problems of PS plastic pollution in ocean environments.

AB - Rapid urbanization and economic growth has led to significant increase in municipal solid waste generation in India during the last few decades and its management has become a major issue because of poor waste management practices. Solid waste generated is deposited into open dumping sites with hardly any segregation and processing. Carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) are the major greenhouse gases that are released from the landfill sites due to the biodegradation of organic matter. In this present study, CH4 and CO2 emissions from a landfill in north-east India are estimated using a flux chamber during September, 2015 to August, 2016. The average emission rates of CH4 and CO2 are 68 and 92 mg/min/m2, respectively. The emissions are highest in the summer whilst being lowest in winter. The diurnal variation of emissions indicated that the emissions follow a trend similar to temperature in all the seasons. Correlation coefficients of CH4 and temperature in summer, monsoon and winter are 0.99, 0.87 and 0.97, respectively. The measured CH4 in this study is in the range of other studies around the world. Modified Triangular Method (MTM), IPCC model and the USEPA Landfill gas emissions model (LandGEM) were used to predict the CH4 emissions during the study year. The consequent simulation results indicate that the MTM, LandGEM-Clean Air Act, LandGEM-Inventory and IPCC models predict 1.9, 3.3, 1.6 and 1.4 times of the measured CH4 emission flux in this study. Assuming that this higher prediction of CH4 levels observed in this study holds well for other landfills in this region, a new CH4 emission inventory (Units: Tonnes/year), with a resolution of 0.10 * 0.10 has been developed. This study stresses the importance of biodegradable composition of waste and meteorology, and also points out the drawbacks of the widely used landfill emission models. PMID- 29175481 TI - Purification, characterization and biological effect of lectin from the marine sponge Stylissa flexibilis (Levi, 1961). AB - SFL, a lectin from the marine sponge Stylissa flexibilis was purified by cold ethanol precipitation followed by ion exchange chromatography on DEAE Sepharose column and Sephacryl S-200 gel filtration. SFL is a dimeric glycoprotein of 32kDa subunits linked by a disulfide bridge with a molecular mass of 64kDa by SDS-PAGE and 65kDa by Sephacryl S-200 gel filtration. SFL preferentially agglutinated enzyme treated human A erythrocytes. The activity of lectin was strongly inhibited by monosaccharide d-galactose and glycoproteins asialo-porcine stomach mucin and asialo-fetuin. The lectin was Ca2+ dependent, stable over a range of pH from 5 to 8, and up to 60 degrees C for 30min. The N-terminal amino acid sequence of SFL was also determined and a blast search on amino acid sequences revealed that the protein showed similarity only with lectins from the marine sponge Spheciospongia vesparia. SFL caused agglutination of Vibrio alginolyticus and V. parahaemolyticus in a dose dependent manner and inhibited the growth rates of the virulent bacterial strains. Growth inhibition of V. alginolyticus and V. parahaemolyticus with SFL was not observed in the presence of d-galactose or asialo-porcine stomach mucin, suggesting that the lectin caused the agglutination through binding to the target receptor(s) on the surface of Vibrios. Thus, the marine sponge S. flexibilis could promise to be a good source of a lectin(s) that may be useful as a carbohydrate probe and an antibacterial reagent. PMID- 29175482 TI - Impacts of wastewater treatment plant effluent on energetics and stress response of rainbow darter (Etheostoma caeruleum) in the Grand River watershed. AB - The objective of this study was to assess the effects of municipal wastewater treatment plant effluent on the energetics and stress response of rainbow darter (Etheostoma caeruleum). Male and female rainbow darter were collected upstream and downstream of the Waterloo WWTP in the Grand River watershed, ON, Canada. To assess the effects of wastewater treatment plant effluent on whole-body and tissue specific metabolic capacity, closed-chamber respirometry and muscle-enzyme activity analyses were performed. Plasma cortisol was also collected from fish before and after an acute air-exposure stressor to evaluate the cortisol stress response in fish exposed to additional stressors. Male and female rainbow darter collected downstream of the effluent had higher oxygen consumption rates, while differences in enzyme activities were primarily associated with sex rather than collection site. No impairment in the cortisol stress response between downstream and upstream fish was observed, however baseline cortisol levels in female fish from the downstream site were significantly higher compared to other baseline groups. Stress-induced cortisol levels were also higher in female fish from both sites when compared to their male counterparts. Overall, this study demonstrates that chronic exposure to WWTP effluent impacts whole-body metabolic performance. This study was also able to demonstrate that sex-differences are a key determinant of various metabolic changes in response to physiological stress, thereby, providing a novel avenue to be considered and further explored. PMID- 29175484 TI - Effects of hypoxia at different life stages on locomotory muscle phenotype in deer mice native to high altitudes. AB - Animals native to high altitude must overcome the constraining effects of hypoxia on tissue O2 supply to support routine metabolism, thermoregulation in the cold, and exercise. Deer mice (Peromyscus maniculatus) native to high altitude have evolved an enhanced aerobic capacity in hypoxia, along with increased capillarity and oxidative capacity of locomotory muscle. Here, we examined whether exposure to chronic hypoxia during development or adulthood affects muscle phenotype. Deer mice from a highland population were bred in captivity at sea level, and exposed to normoxia or one of four treatments of hypobaric hypoxia (12kPa O2, simulating hypoxia at ~4300m): adult hypoxia (6-8weeks), post-natal hypoxia (birth to adulthood), pre-natal hypoxia (before conception to adulthood), and parental hypoxia (in which mice were conceived and raised in normoxia, but their parents were previously exposed to hypoxia). Litter size was similar across treatments, and pups survived the hypoxia exposures and grew to similar body masses at ~6 8months of age. Hypoxia had no effect on the masses of gastrocnemius and soleus muscles. There was a strong concordance between two distinct histological methods for staining capillaries in the gastrocnemius - alkaline phosphatase activity and binding of Griffonia simplicifolia lectin I - each of which showed that capillarity and muscle fibre size were largely unaffected by hypoxia. Maximal activities of several metabolic enzymes (cytochrome c oxidase, citrate synthase, isocitrate dehydrogenase, and lactate dehydrogenase) in the gastrocnemius were also largely unaffected by hypoxia. Therefore, the evolved muscle phenotype of high-altitude deer mice is relatively insensitive to hypoxia across life stages. PMID- 29175480 TI - Diagnostic imaging in the management of patients with metabolic syndrome. AB - Metabolic syndrome (MetS) is the constellation of metabolic risk factors that might foster development of type 2 diabetes and cardiovascular disease. Abdominal obesity and insulin resistance play a prominent role among all metabolic traits of MetS. Because intervention including weight loss can reduce these morbidity and mortality in MetS, early detection of the severity and complications of MetS could be useful. Recent advances in imaging modalities have provided significant insight into the development and progression of abdominal obesity and insulin resistance, as well as target organ injuries. The purpose of this review is to summarize advances in diagnostic imaging modalities in MetS that can be applied for evaluating each components and target organs. This may help in early detection, monitoring target organ injury, and in turn developing novel therapeutic target to alleviate and avert them. PMID- 29175485 TI - Short- and Long-term Exposure to Low and High Dose Running Produce Differential Effects on Hippocampal Neurogenesis. AB - Continuous running wheel (RW) exercise increases adult hippocampal neurogenesis in the dentate gyrus (DG) of rodents. Evidence suggests that greater amounts of RW exercise does not always equate to more adult-generated neurons in hippocampus. It can also be argued that continuous access to a RW results in exercise levels not representative of human exercise patterns. This study tested if RW paradigms that more closely represent human exercise patterns (e.g. shorter bouts, alternating daily exercise) alter neurogenesis. Neurogenesis was measured by examining the survival and fate of bromodeoxyuridine (BrdU)-labeled proliferating cells in the DG of male Sprague-Dawley rats after acute (14 days) or chronic (30 days) RW access. Rats were assigned to experimental groups based on the number of hours that they had access to a RW over two days: 0 h, 4 h, 8 h, 24 h, and 48 h. After acute RW access, rats that had unlimited access to the RW on alternating days (24 h) had a stronger neurogenic response compared to those rats that ran modest distances (4 h, 8 h) or not at all (0 h). In contrast, following chronic RW access, rats that ran a moderate amount (4 h, 8 h) had significantly more surviving cells compared to 0 h, 24 h, and 48 h. Linear regression analysis established a negative relationship between running distance and surviving BrdU+ cells in the chronic RW access cohort (R2 = 0.40). These data demonstrate that in rats moderate amounts of RW exercise are superior to continuous daily RW exercise paradigms at promoting hippocampal neurogenesis in the long-term. PMID- 29175483 TI - The effects of dietary beta-guanidinopropionic acid on growth and muscle fiber development in juvenile red porgy, Pagrus pagrus. AB - beta-guanidinopropionic acid (beta-GPA) has been used in mammalian models to reduce intracellular phosphocreatine (PCr) concentration, which in turn lowers the energetic state of cells. This leads to changes in signaling pathways that attempt to re-establish energetic homeostasis. Changes in those pathways elicit effects similar to those of exercise such as changes in body and muscle growth, metabolism, endurance and health. Generally, exercise effects are beneficial to fish health and aquaculture, but inducing exercise in fishes can be impractical. Therefore, this study evaluated the potential use of supplemental beta-GPA to induce exercise-like effects in a rapidly growing juvenile teleost, the red porgy (Pagrus pagrus). We demonstrate for the first time that beta-GPA can be transported into teleost muscle fibers and is phosphorylated, and that this perturbs the intracellular energetic state of the cells, although to a lesser degree than typically seen in mammals. beta-GPA did not affect whole animal growth, nor did it influence skeletal muscle fiber size or myonuclear recruitment. There was, however, an increase in mitochondrial volume within myofibers in treated fish. GC/MS metabolomic analysis revealed shifts in amino acid composition of the musculature, putatively reflecting increases in connective tissue and decreases in protein synthesis that are associated with beta-GPA treatment. These results suggest that beta-GPA modestly affects fish muscle in a manner similar to that observed in mammals, and that beta-GPA may have application to aquaculture by providing a more practical means of generating some of the beneficial effects of exercise in fishes. PMID- 29175486 TI - Targeting the 15-keto-PGE2-PTGR2 axis modulates systemic inflammation and survival in experimental sepsis. AB - Sepsis is a systemic inflammation accompanied by multi-organ dysfunction due to microbial infection. Prostaglandins and their metabolites have long been studied for their importance in regulating the innate immune response. 15-keto-PGE2 (15k PGE2) is a prostaglandin E2 (PGE2) metabolite, whose further processing is catalyzed by prostaglandin reductase 2 (PTGR2). We showed disruption of the Ptgr2 gene in mice improves the survival rate under both LPS- and cecum ligation/puncture (CLP)-induced experimental sepsis. Knockdown of PTGR2 showed significant accumulation of intracellular 15k-PGE2 in activated macrophages. Both PTGR2 knockdown and exogenous treatment with 15k-PGE2 resulted in reduced pro inflammatory cytokines production in LPS-stimulated RAW264.7 cells or bone marrow derived macrophages (BMDM). The same treatment in RAW264.7 and BMDM also led to increased levels of the anti-oxidative transcription factor, Nuclear factor (erythroid-2) related factor-2 (NRF2), augmented anti-oxidant response element (ARE)-mediated reporter activity and upregulated expression of the corresponding anti-oxidant genes. 15k-PGE2 further demonstrated modification to Kelch-like ECH associated protein 1 (Keap1), a negative regulator of Nrf2, at cysteine 288 (Cys288) site post-translationally. Finally, 15k-PGE2-treated mice were found to be more resistant to experimental sepsis. Taken together, our study affirms the significance of PTGR2 and 15k-PGE2 in mitigating inflammatory responses and suggests a novel anti-oxidative and anti-inflammatory therapy for sepsis through targeting PTGR2 and administering15k-PGE2.

PMID- 29175488 TI - Influence of the epileptiform discharge microenvironment on the differentiation of oligodendrocyte precursor cells. AB - The use of related cell cultured models to investigate the genesis and development of epilepsy is beneficial for exploring the mechanism of epileptogenesis. Recent reports have described the myelination damage caused by epilepsy in animal models; however, limited reports have focused on the influence of epilepsy on remyelination in vitro. The current study was designed to investigate the effect of the epileptiform discharge microenvironment on the differentiation of oligodendrocyte precursor cells (OPCs). Neurons with epileptiform discharge released more glutamic acid than normal neurons, which was detected by HPLC. The RT-qPCR, immunofluorescence and Western Blot results showed myelin basic protein (MBP) loss in the epileptiform discharge neuron microenvironment, with increased GluR2 subunit expression. In addition, an alpha amino-3-hydroxy-5-methyl-4-isoazolepropionic acid (AMPA) receptor antagonist altered the influence of epilepsy on OPC differentiation. This study confirmed the positive effect of epilepsy on the differentiation of OPCs and verified the critical role of glutamic acid and the AMPA receptor in this process, which provides a potential treatment strategy for epilepsy. PMID- 29175489 TI - Diffusion tensor imaging identifies presymptomatic axonal degeneration in the spinal cord of ALS mice. AB - Extensive pathological evidence indicates that axonal degeneration represents an early and critical event in amyotrophic lateral sclerosis (ALS). Unfortunately, few MRI studies have focused in the early detection of white matter (WM) alterations in the spinal cord region. To unveil these WM changes, we performed high resolution diffusion tensor imaging (DTI) and correlated the results with histological analysis of adjacent slices taken from the spinal cords of presymptomatic mice. The DTI studies demonstrated a significant reduction in fractional anisotropy (FA) as well as axial diffusivities (AD) and an increase in radial diffusivity (RD), predominantly at lower segments of the spinal cord. Increases in FA and a reduction in AD and RD were observed in spinal cord (SC) gray matter (GM). Diffusion changes are associated with early and progressive alterations in axonal connectivity following a distal to proximal progression. Histological data tagging neuronal, axonal and glial cell markers demonstrated presymptomatic alterations in spinal cord WM and GM. This study demonstrates that DTI methods are optimal preclinical imaging tools to detect structural anomalies in WM and GM spinal cord during early stages of the disease. PMID- 29175490 TI - Impact of two follow-up schemes on morbidity management and disability prevention (MMDP) programme for filarial lymphedema in Matara, Sri Lanka. AB - Alleviating morbidity due to lymphatic filariasis (LF)-especially in elderly patients who are rather ignorant-is presently the biggest challenge for the national filariasis campaign. We introduced two follow-up schemes and compared each other to address three key programmatic issues (1) locating patients, (2) educating patients, family members on practice of lymphoedema self-care (3) well sustained daily self-care. Hundred and seven lymphoedema patients were introduced to the new Community Home Based Care (CHBC) programme as a part of MMDP programme at their homes. Twenty seven of 107 patients were selected by purposive sampling and followed-up under two schemes, 14 in Daily follow-up (DFU) scheme and 13 in Monthly follow-up (MFU) scheme. Impact was assessed using a KAP score, number of entry lesions (EL) and number of ADL episodes, limb volume, its appearance, changes in the quality of life and gained benefits. Visiting patients in their homes to introduce lymphoedema care programme was a success. KAP scores of the more important activities on lymphoedema care were significantly higher in DFU scheme. Number of patients (51.9%; 14/27) who had EL/s at baseline reduced significantly to 18.5% (5/27) at one year follow-up. The mean numbers of ADL episodes/year reduced significantly in both schemes. Six photographs of 27 showed obvious improvement in lymphoedema and its grade. Mean volume of lymphoedema reduced significantly in both schemes at one year no significant difference between schemes. Benefit score at one year revealed that the patients in DFU scheme received significantly higher amount of benefits compared to MFU scheme. In conclusion daily instruction has significantly motivated the patient and his/her family bringing a new hope. PMID- 29175491 TI - Deformation mechanism and mechanical properties of a thermomechanically processed beta Ti-28Nb-35.4Zr alloy. AB - The effects of thermomechanical treatment on the microstructure and mechanical properties of a newly developed beta titanium alloy, i.e., Ti-28Nb-35.4Zr (wt%, hereafter denoted Ti-Nb-Zr) were investigated. The as-cast Ti-Nb-Zr alloy was subjected to solution treatment at 890 degrees C for 1h, after which its thickness was reduced by 20%, 56%, 76%, and 86% via cold rolling. Results indicated that annealing at 890 degrees C for 1h after cold rolling at a thickness reduction ratio of 86% resulted in a phase transformation from the stress-induced alpha" and omega into beta, leading to a recrystallization of a uniform single beta phase. The recrystallized Ti-Nb-Zr alloy exhibited a tensile strength of 633MPa, Young's modulus of 63GPa, and elongation at rupture of 13%, respectively. The cold rolled specimens showed a higher Young's modulus than that of the recrystallized specimen due to the stress-induced omega phase. Transmission electron microscopy (TEM) analysis revealed that omega, alpha" and beta phases co-existed in the microstructure of the cold-rolled specimens. Electron backscatter diffraction analysis revealed that the deformation mechanisms during thermomechanical processing included kink bands, {332}<113> twins and shear bands; and the predominant deformation mechanism depended on the extent of CR deformation. PMID- 29175492 TI - Shrinkage / stress reduction and mechanical properties improvement in restorative composites formulated with thio-urethane oligomers. AB - Thio-urethane oligomers (TUs) have been shown to favorably modify methacrylate networks to reduce stress and significantly increase fracture toughness. Since those are very desirable features in dental applications, the objective of this work was to characterize restorative composites formulated with the addition of TUs. TUs were synthesized by combining thiols - pentaerythritol tetra-3 mercaptopropionate (PETMP) or trimethylol-tris-3-mercaptopropionate (TMP) - with isocyanates - 1,6-Hexanediol-diissocyante (HDDI) (aliphatic) or 1,3-bis(1 isocyanato-1-methylethyl)benzene (BDI) (aromatic) or dicyclohexylmethane 4,4' Diisocyanate (HMDI) (cyclic), at 1:2 isocyanate:thiol, leaving pendant thiols. 20wt% TU were added to BisGMA-TEGDMA (70-30%). To this organic matrix, 70wt% silanated inorganic fillers were added. Near-IR was used to follow methacrylate conversion and rate of polymerization (Rpmax). Mechanical properties were evaluated in three-point bending (ISO 4049) for flexural strength/modulus (FS/FM) and toughness (T), and notched specimens (ASTM Standard E399-90) for fracture toughness (KIC). Polymerization stress (PS) was measured on the Bioman. Volumetric shrinkage (VS) was measured with the bonded disk technique. Glass transition temperature (Tg) and heterogeneity of network were obtained with dynamic mechanical analysis. The addition of TUs led to an increase in mechanical properties (except for Tg and FS). Fracture toughness ranged from 1.6-1.94MPam1/2 for TU-modified groups, an increase of 33-61% in relation to the control (1.21 +/ 0.1MPam1/2). Toughness showed a two-fold increase in relation to the control: from 0.91MPa to values ranging from 1.70-1.95MPa. Flexural modulus was statistically higher for the TU-modified groups. The Tg, as expected, decreased for all TU groups due to the greater flexibility imparted to the network (which also explains the increase in toughness and fracture toughness). Narrower tan delta peaks suggest more homogeneous networks for the TU-modified materials, though differences were marked only for TMP_AL. Degree of conversion was not affected by the addition of TUs. VS was similar for all groups, with one exception where VS dropped (PETMP-cyclic). Finally, PS showed a reduction of 23 57% for TU-modified groups (6.7 +/- 1.3 to 11.9 +/- 1.0MPa) in relation to the control (15.56 +/- 1.4MPa). The addition of thio-urethane oligomers was able to reduce polymerization stress by up to 57% while increasing fracture toughness by up to 61%. PMID- 29175493 TI - Efficiency and safety of ketamine for pain relief after laparoscopic cholecystectomy: A meta-analysis from randomized controlled trials. AB - OBJECTIVE: This meta-analysis aims to evaluate the effectiveness of intravenous infusion of ketamine for pain control after laparoscopic cholecystectomy (LC). METHODS: A systematic search was performed in PubMed (1966-2017.08), Medline (1966-2017.08), Embase (1980-2017.08), ScienceDirect (1985-2017.08) and the Cochrane Library. Only randomized controlled trials (RCTs) were included. Meta analysis was performed using Stata 11.0 software. RESULTS: A total of six RCTs were retrieved involving 294 patients. The present meta-analysis showed that there were significant differences between groups in terms of visual analogue scale scores at 12 h (WMD = -0.478, 95% CI: -0.934 to -0.021, P = 0.040), 24 h (WMD = -0.550, 95% CI: -1.099 to -0.002, P = 0.049), and 48 h (WMD = -0.350, 95% CI: -0.678 to -0.021, P = 0.037) after LC. Significant differences were found regarding opioid consumption at 12 h (WMD = -2.820, 95% CI: -5.170 to -0.470, P = 0.019), 24 h (WMD = -3.816, 95% CI: -7.155 to -0.478, P = 0.025), and 48 h (WMD = -2.210, 95% CI: -4.046 to -0.375, P = 0.018) after LC. CONCLUSION: Intravenous ketamine infusion significantly reduced postoperative pain scores and opioid consumption after LC. In addition, there were fewer adverse effects in the ketamine groups. Higher quality RCTs are still required for further research. PMID- 29175494 TI - Unfolding the hippocampus: An intrinsic coordinate system for subfield segmentations and quantitative mapping. AB - The hippocampus, like the neocortex, has a morphological structure that is complex and variable in its folding pattern, especially in the hippocampal head. The current study presents a computational method to unfold hippocampal grey matter, with a particular focus on the hippocampal head where complexity is highest due to medial curving of the structure and the variable presence of digitations. This unfolding was performed on segmentations from high-resolution, T2-weighted 7T MRI data from 12 healthy participants and one surgical patient with epilepsy whose resected hippocampal tissue was used for histological validation. We traced a critical image feature composed of the hippocampal sulcus and stratum radiatum lacunosum-moleculare, (SRLM) in these images, then employed user-guided semi-automated techniques to detect and subsequently unfold the surrounding hippocampal grey matter. This unfolding was performed by solving Laplace's equation in three dimensions of interest (long-axis, proximal-distal, and laminar). The resulting 'unfolded coordinate space' provides an intuitive way of mapping the hippocampal subfields in 2D space (long-axis and proximal-distal), such that similar borders can be applied in the head, body, and tail of the hippocampus independently of variability in folding. This unfolded coordinate space was employed to map intracortical myelin and thickness in relation to subfield borders, which revealed intracortical myelin differences that closely follow the subfield borders used here. Examination of a histological resected tissue sample from a patient with epilepsy reveals that our unfolded coordinate system has biological validity, and that subfield segmentations applied in this space are able to capture features not seen in manual tracing protocols. PMID- 29175495 TI - Dynamics of perceptual decisions about symmetry in visual cortex. AB - Neuroimaging studies have identified multiple extra-striate visual areas that are sensitive to symmetry in planar images (Kohler et al., 2016; Sasaki et al., 2005). Here, we investigated which of these areas are directly involved in perceptual decisions about symmetry, by recording high-density EEG in participants (n = 25) who made rapid judgments about whether an exemplar image contained rotation symmetry or not. Stimulus-locked sensor-level analysis revealed symmetry-specific activity that increased with increasing order of rotation symmetry. Response-locked analysis identified activity occurring between 600 and 200 ms before the button-press, that was directly related to perceptual decision making. We then used fMRI-informed EEG source imaging to characterize the dynamics of symmetry-specific activity within an extended network of areas in visual cortex. The most consistent cortical source of the stimulus-locked activity was VO1, a topographically organized area in ventral visual cortex, that was highly sensitive to symmetry in a previous study (Kohler et al., 2016). Importantly, VO1 activity also contained a strong decision-related component, suggesting that this area plays a crucial role in perceptual decisions about symmetry. Other candidate areas, such as lateral occipital cortex, had weak stimulus-locked symmetry responses and no evidence of correlation with response timing. PMID- 29175496 TI - Motion processing after sight restoration: No competition between visual recovery and auditory compensation. AB - The present study tested whether or not functional adaptations following congenital blindness are maintained in humans after sight-restoration and whether they interfere with visual recovery. In permanently congenital blind individuals both intramodal plasticity (e.g. changes in auditory cortex) as well as crossmodal plasticity (e.g. an activation of visual cortex by auditory stimuli) have been observed. Both phenomena were hypothesized to contribute to improved auditory functions. For example, it has been shown that early permanently blind individuals outperform sighted controls in auditory motion processing and that auditory motion stimuli elicit activity in typical visual motion areas. Yet it is unknown what happens to these behavioral adaptations and cortical reorganizations when sight is restored, that is, whether compensatory auditory changes are lost and to which degree visual motion processing is reinstalled. Here we employed a combined behavioral-electrophysiological approach in a group of sight-recovery individuals with a history of a transient phase of congenital blindness lasting for several months to several years. They, as well as two control groups, one with visual impairments, one normally sighted, were tested in a visual and an auditory motion discrimination experiment. Task difficulty was manipulated by varying the visual motion coherence and the signal to noise ratio, respectively. The congenital cataract-reversal individuals showed lower performance in the visual global motion task than both control groups. At the same time, they outperformed both control groups in auditory motion processing suggesting that at least some compensatory behavioral adaptation as a consequence of a complete blindness from birth was maintained. Alpha oscillatory activity during the visual task was significantly lower in congenital cataract reversal individuals and they did not show ERPs modulated by visual motion coherence as observed in both control groups. In contrast, beta oscillatory activity in the auditory task, which varied as a function of SNR in all groups, was overall enhanced in congenital cataract reversal individuals. These results suggest that intramodal plasticity elicited by a transient phase of blindness was maintained and might mediate the prevailing auditory processing advantages in congenital cataract reversal individuals. By contrast, auditory and visual motion processing do not seem to compete for the same neural resources. We speculate that incomplete visual recovery is due to impaired neural network turning which seems to depend on early visual input. The present results demonstrate a privilege of the first arriving input for shaping neural circuits mediating both auditory and visual functions. PMID- 29175497 TI - Spatiotemporal characterization of breathing-induced B0 field fluctuations in the cervical spinal cord at 7T. AB - Magnetic resonance imaging and spectroscopy of the spinal cord stand to benefit greatly from the increased signal-to-noise ratio of ultra-high field. However, ultra-high field also poses considerable technical challenges, especially related to static and dynamic B0 fields. Breathing causes the field to fluctuate with the respiratory cycle, giving rise to artifacts such as ghosting and apparent motion in images. We here investigated the spatial and temporal characteristics of breathing-induced B0 fields in the cervical spinal cord at 7T. We analyzed the magnitude and spatial profile of breathing-induced fields during breath-holds in an expired and inspired breathing state. We also measured the temporal field evolution during free breathing by acquiring a time series of fast phase images, and a principal component analysis was performed on the measured field evolution. In all subjects, the field shift was largest around the vertebral level of C7 and lowest at the top of the spinal cord. At C7, we measured peak-to-peak field fluctuations of 36 Hz on average during normal free breathing; increasing to on average 113 Hz during deep breathing. The first principal component could explain more than 90% of the field variations along the foot-head axis inside the spinal cord in all subjects. We further implemented a proof-of-principle shim correction, demonstrating the feasibility of using the shim system to compensate for the breathing-induced fields inside the spinal cord. Effective correction strategies will be crucial to unlock the full potential of ultra-high field for spinal cord imaging. PMID- 29175498 TI - Neuroimaging of stroke recovery from aphasia - Insights into plasticity of the human language network. AB - The role of left and right hemisphere brain regions in language recovery after stroke-induced aphasia remains controversial. Here, we summarize how neuroimaging studies increase the current understanding of functional interactions, reorganization and plasticity in the language network. We first discuss the temporal dynamics across the time course of language recovery, with a main focus on longitudinal studies from the acute to the chronic phase after stroke. These studies show that the functional contribution of perilesional and spared left hemisphere as well as contralesional right hemisphere regions to language recovery changes over time. The second section introduces critical variables and recent advances on early prediction of subsequent outcome. In the third section, we outline how multi-method approaches that combine neuroimaging techniques with non-invasive brain stimulation elucidate mechanisms of plasticity and reorganization in the language network. These approaches provide novel insights into general mechanisms of plasticity in the language network and might ultimately support recovery processes during speech and language therapy. Finally, the neurobiological correlates of therapy-induced plasticity are discussed. We argue that future studies should integrate individualized approaches that might vary the combination of language therapy with specific non invasive brain stimulation protocols across the time course of recovery. The way forward will include the combination of such approaches with large data sets obtained from multicentre studies. PMID- 29175499 TI - Visualization of porcine eye anatomy by X-ray microtomography. AB - The aim of our study is to obtain, as accurately as possible, porcine ocular tissue visualization using microtomography (micro-CT) method. We propose image contrast enhancement by different staining procedures with combination of micro CT scanning. Porcine eye globes were investigated with Bruker-SkyScan 1172 micro CT. We used 4F1G and Bouin's as sample fixation solutions and tincture of iodine, 100% Lugol, phosphotungstic acid and 1% osmium tetroxide solutions for staining. Quantitative and qualitative analysis was performed based on micro-CT reconstruction images histograms and 3D volume rendering models of investigated samples. This investigation showed that staining methods improved micro-CT image quality in case of ocular anatomy visualization. Characteristic profiles of the grey level distributions and quality of the cross-section and 3D volume rendering images confirmed the staining effect. Most significant contrast enhancement was obtained after 96 h staining in osmium tetroxide and Lugol solutions. The images of eye anatomical structures were characterized: cornea, lens, iris, ciliary body, vitreous, retina, choroid and sclera, vasculature and optic nerve. Staining of porcine eye globes used in this work leads to quality improvement of the micro CT imaging. The most contrast images were obtained for Lugol and osmium tetroxide solutions. Different affinity of staining solutions to eye anatomical structures has been observed in the obtained images. Osmium tetroxide provides sharper image of conjunctiva, sclera, choroid, retina, iris and ciliary body structure. Lugol staining leads to more accurate vessels, cornea and optic nerve imagining.

This study prospectively investigated the relationship between cortisol, sulphate dehydroepiandrosterone (DHEA(S) and cortisol: DHEA(S) ratio and memory in 35 first-episode psychosis (FEP) patients during the first 12 weeks of treatment and 23 healthy controls (HC). METHODS: Morning blood sampling and tests of attention, working memory and verbal memory occurred at baseline and 12-week follow-up. RESULTS: FEP and HC groups did not significantly differ in levels of cortisol, DHEA(S) or their ratio at baseline or over 12-weeks. The FEP group performed significantly below HC on all cognitive measures at baseline and over 12-weeks. Cortisol levels were unrelated to cognition in both groups. At baseline, DHEA(S) was positively associated with attention in HCs, but negatively associated with attention in FEP participants. Change in DHEA(S) was negatively associated with change in memory over 12-weeks in both groups. At 12-weeks, there was a negative correlation between the cortisol: DHEA(S) ratio and attention in both groups. CONCLUSIONS: These findings are mostly in contrast to findings in chronic schizophrenia. Investigation at different illness phases and over longer-follow-up periods is required to determine the complex relationship between HPA-axis and memory functioning in psychosis.

AB - The aim of this study was to examine (1) suicide trends by most prevalent methods in Queensland, Australia, during 2000-2015, and (2) characteristics of people by choice of suicide method in 2000-2013. Data were obtained from the Queensland Suicide Register, which includes police and toxicology reports, post-mortem autopsy and Coroner's findings. Poisson and Joinpoint regression were used to study the first aim, and uni-variate and multi-variate logistic regression analyses were applied to investigate the second aim. Suicide method trends showed a significant increase in hanging for both sexes and poisoning with drugs for females, while there was a decline for poisoning by other means for both sexes, and 'other methods' decreased for males. Changes in the trends have altered the order of suicide methods, especially in males. Analyses of 8140 suicides were composed by the choice of method, distinguishable profiles by their demographic, clinical and social characteristics, such as having mental or physical illness or different recent life stressors were identified. This suggests that socio cultural acceptability, and availability are the key drivers in the choice of suicide methods. Continuing increases in hanging is a big challenge in suicide prevention due to its lethality, easy realisation and its increasing acceptability.

AB - In 2005, 15 years after the introduction of the diagnosis in DSM-III, a telephone survey in Germany revealed that the public was still unfamiliar with the term bipolar disorder. Only 5.3% of those questioned knew at the time that it denotes a mental illness. In the meantime, efforts have been made to spread the concept among the public. In the media there has been increasing mention of the disorder. Another telephone survey in 2017 showed that familiarity with the diagnostic term has grown substantially. 54.0% of respondents now connected the term bipolar disorder with a mental illness. PMID- 29175503 TI - Non literal language comprehension in a large sample of first episode psychosis patients in adulthood. AB - To date no data still exist on the comprehension of figurative language in the early phases of psychosis. The aim of this study is to investigate for the first time the comprehension of metaphors and idioms at the onset of the illness. Two hundred-twenty eight (228) first episode psychosis (FEP) patients (168 NAP, non affective psychosis; 60 AP, affective psychosis) and 70 healthy controls (HC) were assessed. Groups were contrasted on: a) type of stimulus (metaphors vs idioms) and b) type of response (OPEN = spontaneous explanations vs CLOSED = multiple choice answer). Moreover, a machine learning (ML) approach was adopted to classifying participants. Both NAP and AP had a poorer performance on OPEN metaphors and idioms compared to HC, with worse results on spontaneous interpretation of idioms than metaphors. No differences were observed between NAP and AP in CLOSED tasks. The ML approach points at CLOSED idioms as the best discriminating variable, more relevant than the set of pre-frontal and IQ scores. Deficits in non-figurative language may represent a core feature of psychosis. The possibility to identify linguistic features discriminating FEP may support the early recognition of patients at risk to develop psychosis, guiding provision of personalized and timely interventions. PMID- 29175504 TI - Neurological soft signs, dissociation and alexithymia in patients with obsessive compulsive disorder (OCD) and healthy subjects. AB - A body of evidence has supported that patients with obsessive-compulsive disorder (OCD) have increased rates of various neurological soft signs (NSS) compared to controls. Various lines of research has documented robust relationships between OCD and dissociative symptomatology. The study aimed to examine the associations between obsessive-compulsive symptoms, dissociative experiences alexithymia, and NSS. The study included thirty OCD patients and thirty healthy controls, matched for age, marital status, education, and income. The Neurological Evaluation Scale (NES), Padua Inventory-Revised (PI-R), Dissociative Experiences Scale (DES) and Toronto Alexithymia Scale (TAS-20) were administered. In comparison to healthy controls, patients with OCD had difficulty sequencing for complex motor acts and greater absorption/ imaginative involvement. Using latent class analysis, the study sample was classified into two homogenous subsets as mild NSS (n = 45) and severe NSS (n = 15). Majority of the participants who were grouped into severe NSS latent class were OCD patient (n = 14, 93.3%). Furthermore, those with severe NSS reported greater levels of alexithymia and more severe obsessive-compulsive symptoms, particularly precision. We concluded that relationships between OCD severity and NSS appear to be of crucial importance. Our data along with accumulated evidence suggest that OCD associated with pronounced NSS may represent a specific subtype of the disorder. PMID- 29175505 TI - Characteristics of induced pluripotent stem cells from clinically divergent female monozygotic twins with Danon disease. AB - RATIONALE: Induced pluripotent stem cells (iPSCs) have been generated from patients with various forms of disease, including Danon disease (DD); however, few reports exist regarding disease-specific iPSCs derived from clinically divergent monozygotic twins. OBJECTIVE: We examined the characteristics of iPSCs and iPSC-derived cardiomyocytes (iPSC-CMs) generated from clinically divergent monozygotic female twins with DD. METHODS AND RESULTS: We generated iPSCs derived from T-cells isolated from clinically divergent, 18-year-old female twins with DD harboring a mutation in LAMP2 at the intron 6 splice site (IVS6+1_4delGTGA). Two divergent populations of iPSCs could prepare from each twin despite of their clinical divergence: one with wild-type LAMP2 expression (WT-iPSCs) and a second with mutant LAMP2 expression (MT-iPSCs). The iPSCs were differentiated into iPSC CMs and then autophagy failure was observed only in MT-iPSC-CMs by electron microscopy, tandem fluorescent-tagged LC3 analysis, and LC3-II western blotting. Under these conditions, X-chromosome inactivation (XCI) was determined by PCR for the (CAG)n repeat in the androgen receptor gene, revealing an extremely skewed XCI pattern with the inactivated paternal wild-type and maternal mutant X chromosomes in MT-iPSCs and WT-iPSCs, respectively, from each twin. CONCLUSION: Regardless of their clinical differences, we successfully established two sets of iPSC lines that expressed either wild-type or mutant LAMP2 allele from each monozygotic twin with DD, of which only the populations expressing mutant LAMP2 showed autophagic failure. PMID- 29175506 TI - CD26 expression is down-regulated on CD8+ T cells in patients with Hashimoto's thyroiditis. AB - The immune mechanism underlying Hashimoto's thyroiditis (HT) remains unclear. CD26, also known as dipeptidyl peptidase 4 (DPP-4), is a multifunctional molecule involved in the pathophysiology of autoimmune diseases. This study aimed to investigate the role of CD26 in the pathogenesis of HT. Peripheral blood was drawn from 20 healthy controls and 31 HT patients (19 mild HT patients and 12 severe HT patients). Plasma sCD26 concentrations were measured by ELISA, and sCD26 enzymatic activity was assessed using a luciferase-based assay. The expression levels of membrane-bound CD26 were analyzed by flow cytometry. Plasma sCD26 concentrations were lower in HT patients than in healthy controls, although the difference in sCD26 concentrations between the two groups did not reach statistical significance (P=0.07). The percentages of CD8+ T cells and Tc1 cells with CD26 expression were decreased in HT patients compared with those in healthy controls, and the mean fluorescence intensity (MFI) values of CD26 on CD8+ T cells and Tc17 cells in HT patients were significantly lower than in healthy controls (P<0.05). In HT patients, the expression of CD26 on CD8+ T cells and Tc subsets was decreased in the hypothyroidism group compared with that in the euthyroid group (P<0.05). These results suggest that the sCD26 concentrations and membrane-bound CD26 levels on CD8+ T cells are aberrant in HT and that the reduced CD26 expression may be involved in the progression of HT. PMID- 29175507 TI - The mast cell stabilizing activity of Chaga mushroom critical for its therapeutic effect on food allergy is derived from inotodiol. AB - While an anti-allergic effect of Chaga mushroom (Inonotus obliquus) has been indicated, its therapeutic effect on allergy and immunoregulatory mechanisms and chemical constituents directly responsible for that are hardly known. We examined the effect of 70% ethanol extract of Chaga mushroom (EE) and its dichloromethane (DF) and aqueous (AF) fractions using a mouse model of chicken ovalbumin (cOVA) induced food allergy, and found that only EE and DF ameliorated allergy symptoms to a significant extent. The in vivo mast cell-stabilizing activity was also found only in EE and DF whereas the activities to suppress Th2 and Th17 immune responses and cOVA-specific IgE production in the small intestine were observed in all three treatment regimens, implying that inhibition of the mast cell function by lipophilic compounds was vital for the therapeutic effect. Results also indicated that inotodiol, a triterpenoid predominantly present in DF, played an active role as a mast cell stabilizer. PMID- 29175508 TI - TNFalpha induces tolerant production of CXC chemokines in colorectal cancer HCT116 cells via A20 inhibition of ERK signaling. AB - Ubiquitin editing enzyme A20 functions as a tumor suppressor in various cancer. However, the mechanism for A20 regulation of cancer progress is not fully understood. In this study, we found that in human colorectal cancer HCT116 cells, TNFalpha induced a tolerant production of CXC chemokines, including CXCL1, 2, and 8 in a dose and time dependent manner. TNFalpha pre-treatment of HCT116 cells down-regulated the chemokine production induced by TNFalpha re-treatment. TNFalpha induced the phosphorylation of MAPKs ERK, JNK, P38 and NF-kappaB P65, but only ERK inhibition decreased TNFalpha-induced chemokine production. Both RT PCR and FACS results showed that TNFalpha treatment did not regulate the expression of TNF receptors. However, TNFalpha up-regulated the expression of A20 at both mRNA and protein levels significantly. TNFalpha pre-treatment inhibited the signal transduction of MAPKs induced by TNFalpha re-stimulation, and A20 over expression decreased the signal transduction of ERK and P38. Meanwhile, A20 inhibition by RNA interference reversed chemokine down-regulation induced by TNFalpha re-stimulation after TNFalpha pre-treatment. Taken together, these results suggested that in human colorectal cancer cells, A20 may function to inhibit cancer progression via down-regulation of TNFalpha-induced chemokine production by suppression of ERK signaling. PMID- 29175510 TI - CT scan assessment in salivary gland lithiasis diagnosis. AB - INTRODUCTION: The aim of the study was to assess computed tomography (CT) scan efficiency for the diagnosis of salivary lithiasis. METHODS: Patients who were included were all the patients who consulted in our department for main salivary gland (submandibular and parotid) obstruction symptoms between June 2014 and December 2016. A CT scan without injection was prescribed for all of them. The 163 patients were divided into two groups after the CT scan: patients with and without lithiasis. During surgery, we confirmed the presence or absence of the lithiasis previously diagnosed on the CT scan. The patients were divided in two groups: case and control groups. For statistical analysis, the sensitivity, specificity, and the negative and positive predictive values of the preoperative CT scan were calculated. RESULTS: A total of 163 patients with a salivary obstructive syndrome were included. On the CT scans, we found lithiases (hyperdense images) in 157 glands ("CT scan?" group), and we found no lithiasis in 6 glands ("CT scan" group). In the "CT scan?" group, 203 lithiases were present. During surgery, we found and removed lithiases in 155 patients (case group), and 8 patients had no lithiases (control group). The overall sensitivity, specificity, positive predictive value, and negative predictive values of the CT scan for the detection of lithiasis were 100%, 75%, 99%, and 100%, respectively. The specificity of CT scans for the lithiasis located in the anterior and middle third of the duct was 100%. DISCUSSION: According to our study, the CT scan is very efficient in diagnosing salivary main gland lithiases in patients with an obstructive syndrome. PMID- 29175511 TI - Speech evaluation after intravelar veloplasty. How to use Borel-Maisonny classification in the international literature? AB - OBJECTIVE: Comparing functional outcomes after velar repair appeared to be difficult because of the absence of international standardized scale. Moreover most of the studies evaluating speech after cleft surgery present multiple biases. The aim of our study was to assess speech outcomes in a homogeneous group of patients, and to define an equivalence table between different speech scales. MATERIALS AND METHODS: Patients with isolated cleft lip and palate (CLP), operated in our unit by the same senior surgeon were included. All patient were operated according to the same protocol (cheilo-rhinoplasty and intravelar veloplasty at 6 months, followed by a direct closure of the hard palate at 15 months). Speech evaluation was performed after 3 year-old and before the alveolar cleft repair. Borel-Maisonny scale and nasometry were used for speech evaluation. RESULTS: Twenty-four patients were included: 17 unilateral CLP and 7 bilateral CLP. According to the Borel-Maisonny classifications, 82.5% were ranged phonation 1, 1-2 or 2b. Nasometry were normal in almost 60% of cases. CONCLUSIONS: This study showed the efficiency of our protocol, and intravelar veloplasty. Moreover we proposed an equivalence table for speech evaluation scale. PMID- 29175512 TI - Altering D1 receptor activity in the basolateral amygdala impairs fear suppression during a safety cue. AB - Accurate discrimination among cues signifying reward, danger or safety initiates the proper emotional response in order to guide behavior. Appropriate conditioned inhibition of fear in the presence of a safety cue would allow an organism to engage in reward seeking behaviors. There is currently little known about the mechanisms of reward, fear and safety cue discrimination and how a safety cue can inhibit fear and release reward seeking from inhibition. Here we assess reward, fear and safety cue learning together using a behavioral paradigm that has identified neurons that discriminate among these cues in the basolateral amygdala (BLA) (Sangha, Chadick, & Janak, 2013). Dopamine signaling in the BLA has been implicated in discriminatory reward learning, learned fear responses and fear extinction. We tested the hypothesis that D1 receptor activity will influence reward-fear-safety cue discrimination by using the D1 receptor agonist, SKF-3839, and antagonist, SCH-23390, either systemically or within the BLA during discrimination learning in male Long Evans rats. We show that both the agonist and antagonist interfered with fear suppression in the presence of the safety cue, when administered systemically or when infused directly into the BLA. This indicates that altering D1 receptor activity in the basolateral amygdala impairs fear suppression during a safety cue. Neither the agonist or antagonist had a consistent negative impact on discriminatory reward seeking when infused into the BLA. However, systemic administration of the D1 receptor agonist did reduce reward seeking behavior during a task that included fear and safety cues. We did not observe a negative impact on reward seeking during systemic administration of a D1 receptor agonist in a task that only included reward cue + sucrose and nonreward cue + no sucrose pairings. This indicates the impairments we saw with the systemically applied agonist in the safety-fear-reward cue discrimination task were more likely due to effects on fear and/or motivation rather than on cue discrimination. Together, our data indicate that altered dopamine D1 receptor activity in the BLA may be a potential mechanism that leads to the impairment in fear suppression to the safety signal seen with PTSD patients. PMID- 29175513 TI - Sleep augments training-induced improvement in working memory in children and adults. AB - Sleep plays an important role in forming procedural motor memories. Whether sleep plays a similar role for cognitive procedures related to working memory function, is not yet clear. Here we investigated if sleep enhances training-induced improvements in working memory in children. Because children show more intense slow wave sleep (e.g., higher slow wave activity, more spindles) we expected sleep-related improvements to be greater than in adults. Twenty-four children (10 12 years) and 24 adults were trained on three sessions of an n-back task comprising three runs of blocks (6 blocks with 20 responses each) presented in ascending levels of difficulty. The sessions were separated by ~12 h. Between the training sessions, participants first spent a full night sleeping and then a normal day awake (evening groups) or vice versa (morning groups). We analyzed performance on the whole blocks and, to estimate the individual's optimum performance, on only the first 10 trials of each block. Results showed a distinct gain in training-induced working memory performance with post-training overnight sleep compared to wakefulness. The sleep-induced gain was revealed only for performance on the first block-halves and, in absolute terms, was closely comparable in children and adults. Taking differences in working memory performance into account sleep-dependent gains expressed as percentages of baseline performance were, however, greater in children than in adults. The data thus indicate that sleep after training facilitates cognitive procedures related to executive control, i.e., the ability to operate sequences of events in working memory, with a particular benefit in developing populations. PMID- 29175514 TI - Reward anticipation modulates the effect of stress-related increases in cortisol on episodic memory. AB - When acute stress is experienced shortly after an event is encoded into memory, this can slow the forgetting of the study event, which is thought to reflect the effect of cortisol on consolidation. In addition, when events are encoded under conditions of high reward they tend to be remembered better than those encoded under non-rewarding conditions, and these effects are thought to reflect the operation of the dopaminergic reward system. Although both modulatory systems are believed to impact the medial temporal lobe regions critical for episodic memory, the manner, and even the extent, to which these two systems interact is currently unknown. To address this question in the current study, participants encoded words under reward or non-reward conditions, then one half of the participants were stressed using the social evaluation cold pressor task and the other half completed a non-stress control task. After a two-hour delay, all participants received a free recall and recognition memory test. There were no significant effects of stress or reward on overall memory performance. However, for the non reward items, increases in stress-related cortisol in stressed participants were related to increases in recall and increases in recollection-based recognition responses. In contrast, for the reward items, increases in stress-related cortisol were not related to increases in memory performance. The results indicate that the stress and the reward systems interact in the way they impact episodic memory. The results are consistent with tag and capture models in the sense that cortisol reactivity can only affect non-reward items because plasticity-related products are already provided by reward anticipation. PMID- 29175516 TI - A lucky mistake: the splenic glands of Marcello Malpighi. AB - Marcello Malpighi (1628-1694) is one of the most important anatomists and physicians in the history of medicine. His contributions to the understanding of human anatomy and physiology span from the first description of capillary circulation to a thorough analysis of the structure and function of body glands. Malpighi believed that most organs consisted of glandular structures, whose distribution and microscopic features determine each organ-specific function. He also applied this view to the study of spleen anatomy, which he recognized as composed of 2 distinct anatomic compartments (ie, the red and the white pulp). Malpighi's observations on the structure and function of the spleen were first published in 1666 in De Viscerum Structura. In this paper, we pay tribute to this work, presenting Malpighi's theory of the spleen as a glandular organ. The rationale of Malpighi's view and its value for contemporary pathologists and medical researchers will also be elucidated. PMID- 29175515 TI - Innate immune control of alphavirus infection. AB - Alphaviruses are important human pathogens that cause diseases ranging from acute and chronic polyarthralgia to encephalitis. Transmitted by mosquito vectors, alphaviruses have high potential for emergence and have initiated several recent epidemics. The innate immune response is critical for controlling the acute phase of alphavirus disease, and the induction of type I interferon (IFN) is essential in this response. In this review, we discuss our current understanding of innate host sensors that initiate antiviral responses following alphavirus infection, and the IFN-induced effector proteins that limit alphavirus replication and dissemination. PMID- 29175517 TI - Design and simulation of a microfluidic device for acoustic cell separation. AB - Experimental acoustic cell separation methods have been widely used to perform separation for different types of blood cells. However, numerical simulation of acoustic cell separation has not gained enough attention and needs further investigation since by using numerical methods, it is possible to optimize different parameters involved in the design of an acoustic device and calculate particle trajectories in a simple and low cost manner before spending time and effort for fabricating these devices. In this study, we present a comprehensive finite element-based simulation of acoustic separation of platelets, red blood cells and white blood cells, using standing surface acoustic waves (SSAWs). A microfluidic channel with three inlets, including the middle inlet for sheath flow and two symmetrical tilted angle inlets for the cells were used to drive the cells through the channel. Two interdigital transducers were also considered in this device and by implementing an alternating voltage to the transducers, an acoustic field was created which can exert the acoustic radiation force to the cells. Since this force is dependent to the size of the cells, the cells are pushed towards the midline of the channel with different path lines. Particle trajectories for different cells were obtained and compared with a theoretical equation. Two types of separations were observed as a result of varying the amplitude of the acoustic field. In the first mode of separation, white blood cells were sorted out through the middle outlet and in the second mode of separation, platelets were sorted out through the side outlets. Depending on the clinical needs and by using the studied microfluidic device, each of these modes can be applied to separate the desired cells. PMID- 29175518 TI - Social cognitive dysfunction as a clinical marker: A systematic review of meta analyses across 30 clinical conditions. AB - Social cognition includes a range of cognitive processes that help individuals to understand how others think and feel. There is emerging evidence that social cognitive deficits may represent a transdiagnostic issue, potentially serving as a marker of neurological abnormality. We performed an electronic database search in order to identify published, peer-reviewed meta-analyses that compared facial emotion recognition or theory of mind task performance between individuals meeting clinical criteria for a psychiatric, neurological or developmental condition against healthy controls. We identified 31 meta-analyses eligible for inclusion that examined performance across relevant tasks among 30 different clinical populations. The results suggest that social cognitive deficits appear to be a core cognitive phenotype of many clinical conditions. Across the clinical groups, deficits in social cognitive domains were broadly similar in magnitude to those previously reported for more established aspects of cognition, such as memory and executive function. There is a need to clarify the 'real world' impact of these deficits, and to develop effective transdiagnostic interventions for those individuals that are adversely affected.

PMID- 29175519 TI - A new tridecapeptide with an octaarginine vector has analgesic therapeutic potential and prevents morphine-induced tolerance. AB - A growing body of evidence suggests that peptides may possess analgesic effects without tolerance development. The synthetic tetrapeptide Tyr-d-Arg-Phe-Gly-NH2 was modified with the inclusion of a (d-Arg)8 vector to prevent the action of endopeptidase and to increase the duration of the analgesic action of the tetrapeptide when administered orally. The aim of this study was to estimate the analgesic efficacy of the tetrapeptide with (d-Arg)8 (tridecapeptide, TDP) in experimental models of acute and chronic pain. The analgesic effects of TDP were estimated using a model of acute visceral pain in mice (writhing test) and a model of chronic neuropathic pain (chronic constriction injury (CCI) of the sciatic nerve) in rats. The intravenous administration of morphine (0.32-1mg/kg) and TDP (0.32-1.8mg/kg) produced significant dose-related antinociceptive effects in the writhing test. The potency of TDP after i.g. administration was lower than that after i.v. administration but comparable with that of i.g. morphine. In the CCI model, TDP (0.1, 1 and 10mg/kg, i.g.) induced marked analgesia with repeated administration without any signs of tolerance. The single administration of TDP after morphine treatment (7days) produced a significant analgesic effect in morphine-tolerant rats, indicating the absence of cross-tolerance between these two drugs. The combined administration of TDP and morphine resulted in the reduction of analgesic tolerance to morphine. The absence of cross-tolerance to morphine and the ability to prevent morphine tolerance allows this compound to be a prospective candidate for chronic pain therapy. In order to find the target receptors for TDP, a docking study was performed. It was found that the molecule can bind to the NMDA receptor using electrostatic, hydrogen bonding and hydrophobic interactions. PMID- 29175520 TI - Alzheimer's disease-associated ubiquitin mutant Ubb+1: Properties of the carboxy terminal domain and its influence on biomolecular interactions. AB - Ubb+1, a ubiquitin (Ub) mutant protein originating from misreading of the Ub B gene, is found accumulated in brain tissues of Alzheimer's disease patients. The mutant attracts strong interest due to its possible participation in the molecular events leading to neurodegeneration. Ubb+1 is composed of the globular domain of Ub, linked to a 19-residue C-terminal peptide. Based on NMR relaxation and solvent accessibility measurements we obtained new insight into the molecular properties of Ubb+1. We further determined the thermal stability of Ubb+1 in the monomeric form, and in Lys48- and Lys63-linked dimers. Finally, we explored the influence of the C-terminal fragment on the interactions of Ubb+1 with an isolated UBA2 domain and with membrane mimics. Our data indicate that the C terminal fragment of Ubb+1 is overall highly flexible, except for a short stretch which appears less solvent-exposed. While influencing the hydrodynamic properties of the globular domain, the fragment does not establish long-lived interactions with the globular domain. It results that the structure and stability of Ub are minimally perturbed by the peptide extension. However, binding to UBA2 and to membrane mimics are both affected, exemplifying possible changes in biomolecular recognition experienced by the disease-associated Ubb+1 compared to the wild-type protein. PMID- 29175521 TI - Structural analysis of the interaction between free, glycated and fructated hemoglobin with propolis nanoparticles: A spectroscopic study. AB - Non enzymatic Glycation is the main causes of diabetic complications. Propolis is a natural product of different plant exudates and buds which has different biological properties such as anti-hyperglycemia. In attention to better performance of nanoparticles in treatment, we synthesized propolis nanoparticles (PNP) and analyzed their physicochemical properties by dynamic light scattering (DLS), scanning electron microscopy (SEM), Zeta potential and FTIR analyses. Then, the structural changes of human hemoglobin (Hb), in three different forms of free, glycated and fructated Hb upon interaction with PNP at two temperatures of 25 and 37 degrees C were investigated using fluorescence and far-UV circular dichoroism (CD) spectroscopic techniques. The size distribution of PNP was less than 100nm. Fluorescence results indicated that PNP have a strong ability in quenching the intrinsic fluorescence of different forms of Hb. The binding constants, number of binding sites and thermodynamic parameters of these interactions were calculated and compare to each other. The Gibbs free energy values for glycated and fructated Hb with PNP were calculated-1635 and 1065J/mol, respectively at 25 degrees C which indicates that interaction of Hb with PNP is more favorable than interaction of GHb with PNP. CD spectra indicated that PNP lead to no significant changes in the secondary structure of different types of Hb. So, PNP as a natural product, due to antioxidant properties and lack of toxicity, can be used in the drug delivery system. PMID- 29175522 TI - Characterization of cellulosic paper coated with chitosan-zinc oxide nanocomposite containing nisin and its application in packaging of UF cheese. AB - A new antimicrobial bilayer film was developed using chitosan, cellulose, and nisin. Chitosan solution containing nisin (500 and 1000MUg/mL) was prepared by sol-gel method and then the solution was coated on cellulose paper by dip coating method. A chitosan-cellulose film without antimicrobial had no inhibitory effect on Listeria monocytogenes, whereas, the incorporation of nisin made a significant increase (P<0.05) in antimicrobial characteristics of the films. Moreover, no significant differences were shown on antimicrobial activity of developed films during the storage at 4 degrees C for one month. However, the addition of nisin showed a significant increase in the swelling index and solubility of bilayer film. Scanning electron microscope images revealed a uniform coating of chitosan solution on cellulose paper. The FTIR analysis also confirmed successful introducing and binding of the nisin in double layer film. Films with 1000MUg/mL of nisin completely inactivated the initial (~5log10 CFU/g) counts of L. monocytogenes on the surface of Ultra-filter white cheese after storage at 4 degrees C for 14 days. We concluded that nanocomposite film of chitosan-cellulose containing nisin has novel antibacterial activity and can be used for packaging in cheese. PMID- 29175523 TI - Improved mechanical properties and thermal-stability of collagen fiber based film by crosslinking with casein, keratin or SPI: Effect of crosslinking process and concentrations of proteins. AB - This study utilized three different thermo-stable proteins of casein, keratin and soy protein isolate (SPI) to improve the thermal stabilities and mechanical properties of collagen fiber films using transglutaminase (TGase) crosslinking. The crosslinking greatly enhanced the thermal- stability of collagen fiber films, especially that of the collagen fiber crosslinking with 50% casein composite films, judged from thermogravimetric analysis (TGA). Furthermore, the TGase treatment improved the mechanical properties of the collagen fiber films interms of tensile strength (TS) and elongation at break (EAB). Importantly, a prominent improvement in EAB at wet and heated state was noted when collagen fiber crosslinked with 50% keratin or 50% casein, respectively. Moreover, different addition patterns of proteins in the collagen fiber films offered altered morphology as observed by scanning electron microscopy (SEM). Meanwhile, the conformational changes of the films revealed by fourier transform infrared spectroscopy (FTIR) confirmed a greater stabilization of film in the group of collagen fiber crosslinking with other proteins. In conclusion, the crosslinking action induced by TGase between collagen fiber and higher thermo-stable proteins promoted heat-resistance and mechanical properties of collagen fiber based film. PMID- 29175524 TI - Characterization of L-asparaginase from marine-derived Aspergillus niger AKV MKBU, its antiproliferative activity and bench scale production using industrial waste. AB - L-asparaginase (LA), an enzyme with anticancer activities, produced by marine derived Aspergillus niger was subjected to purification and characterization. The purified enzyme was observed to have molecular weight ~90KDa. The enzyme retained activity over a wide range of pH, i.e. pH 4-10. The enzyme was quite stable in temperature range 20-40 degrees C. Tween 80 and Triton X-100 were observed to enhance LA activity while inhibition of LA activity was observed in presence of heavy metals. The values for Km was found to be 0.8141 mM and Vmax was 6.228MUM/mg/min. The enzyme exhibited noteworthy antiproliferative activity against various cancer cell lines tested. Successful bench scale production (in 5L bioreacator) of LA using groundnut oil cake as low cost substrate has also been carried out.

AB - The inhibition of electrons-holes recombination and enhancement of visible light photocatalytic activity were accomplished by the synthesized TiO2/CS nanocomposites system. In this present work, the different weight ratio of TiO2 and chitosan (75:25, 50:50 and 25:75) nanocomposites were synthesized via two step method. After that, the existing functional groups, size and structure of the nanocomposites system were characterized via FT-IR, TEM and XRD measurements. The band gap of the prepared materials and its excitation and emission spectra were elevated through UV-vis and PL analyses. Moreover, the MO and MB degradation capability of the synthesized TiO2/CS nanocomposites was optimized, and the outcomes are described in detail.

AB - S100 proteins are multifunctional (intra/extra)cellular mostly dimeric calcium binding proteins engaged into numerous diseases. We have found that monomeric recombinant human S100P protein interacts with intact human serum albumin (HSA) in excess of calcium ions with equilibrium dissociation constant of 25-50nM, as evidenced by surface plasmon resonance spectroscopy and fluorescent titration by HSA of S100P labelled by fluorescein isothiocyanate. Calcium removal or S100P dimerization abolish the S100P-HSA interaction. The interaction is selective, since S100P does not bind bovine serum albumin and monomeric human S100B lacks interaction with HSA. In vitro glycation of HSA disables its binding to S100P. The revealed selective and highly specific conformation-dependent interaction between S100P and HSA shows that functional properties of monomeric and dimeric forms of S100 proteins are different, and raises concerns on validity of cell based assays and animal models used for studies of (patho)physiological roles of extracellular S100 proteins. PMID- 29175527 TI - Factors That Contribute to Indeterminate Results From the QuantiFERON-TB Gold In Tube Test in Patients With Inflammatory Bowel Disease. AB - BACKGROUND & AIMS: The QuantiFERON-Tuberculosis Gold In-Tube (QFT-GIT) (QIAGEN Group, Hilden, Germany) test is widely used to screen for latent Mycobacterium tuberculosis infection in patients with inflammatory bowel diseases (IBD) before treatment with a tumor necrosis factor antagonist. The test frequently produces indeterminate results, prompting additional testing. We evaluated factors associated with indeterminate results from the QFT-GIT test among patients with IBD. METHODS: We conducted a case-control study among eligible adults with QFT GIT test results and a concomitant diagnosis of IBD receiving care at a tertiary referral center from 2011 through 2013. We compared patients with IBD with indeterminate and determinate (positive or negative) results from the QFT-GIT test. We collected data on patient demographics, clinical features, laboratory parameters, and medication use from medical charts. We calculated odds ratios (OR) and 95% CIs using multivariate logistic regression models. RESULTS: A total of 400 patients with IBD (265 Crohn's disease and 135 ulcerative colitis) were included in the final analyses. Indeterminate results were noted in 11.5% of patients. At the time of testing, a higher proportion of patients with indeterminate results from the QFT-GIT test were on systemic corticosteroid therapy (60.9% vs 30.5% of patients with conclusive test results; P < .001), had levels of C-reactive protein above 0.8 mg (62.2% vs 39.9% of patients with clear test results; P = .005), had an erythrocyte sedimentation rate above 15 mm/h (55.6% vs 35.8% of patients with clear test results; P = .01), had serum levels of albumin below 3.5 g/dL (33.3% vs 6.3% of patients with clear test results; P < .001), and had low levels of hemoglobin (52.2% vs 28.3% of patients with clear test results; P = .001). In multivariable analysis, corticosteroid use (adjusted OR, 2.92; 95% CI, 1.44-5.88; P = .003) and serum levels of albumin below 3.5 g/dL (adjusted OR, 3.62; 95% CI, 1.36-9.60; P = .009) were independently associated with increased risk of indeterminate QFT-GIT test results. We did not identify a dose-related effect with corticosteroid therapy and the odds of indeterminate QFT GIT test results. CONCLUSIONS: In a case-control study of patients with IBD, we associated systemic corticosteroid therapy and low levels of albumin with an increased likelihood of having indeterminate QFT-GIT test result.

PMID- 29175528 TI - Excellent Outcomes of Liver Transplantation Following Down-Staging of Hepatocellular Carcinoma to Within Milan Criteria: A Multicenter Study. AB - BACKGROUND & AIMS: Single-center studies have reported excellent outcomes of patients who underwent liver transplantation for hepatocellular carcinoma (HCC) after successful down-staging (reduction of tumor burden with local-regional therapy), but multi-center studies are lacking. We performed a multi-center study, applying a uniform down-staging protocol, to assess outcomes of liver transplantation and performed an intention to treat analysis. We analyzed factors associated with treatment failure, defined as dropout from the liver transplant waitlist due to tumor progression, liver-related death without transplant, or recurrence of HCC after transplant. METHODS: We performed a retrospective multi center study of 187 consecutive adults with HCC enrolled in the down-staging protocol at 3 liver transplant centers in California (Region 5), from 2002 through 2012. All patients underwent abdominal imaging 1 month after each local regional treatment, and at a minimum of once every 3 months. The primary outcome was probability of treatment failure. RESULTS: Liver transplantation was performed after successful down staging in 109 patients (58%). Tumor explant from only 1 patient had poorly differentiated grade and 7 (6.4%) had vascular invasion. Based on Kaplan-Meier analysis of data collected a median 4.3 years after liver transplantation, 95% of patients would survive 1 year and 80% of patients would survive 5 years; probabilities of recurrence-free survival were 95% and 87%, respectively. There were no center-specific differences in survival in the intention to treat analysis (P = .62), in survival after liver transplantation (P = .95), or in recurrence of HCC (P = .99). Patients were removed from the liver transplantation waitlist due to tumor progression in (n = 59; 32%) or liver-related death without liver transplantation (n = 9; 5%). Factors associated with treatment failure, based on multivariable analysis, were pre-treatment levels of alpha-fetoprotein (AFP) >1000 ng/mL (hazard ratio, 3.3; P < .001) and Child Pugh class B or C (hazard ratio, 1.6; P < .001). The probability of treatment failure at 2 years from the first down-staging procedure was 100% for patients with levels of AFP >1000 and Child Pugh class B or C vs 29.4% for patients with neither risk factor (P < .001). CONCLUSIONS: In a retrospective, multi-center study on HCC down staging under a uniform protocol, we found patients to have excellent outcomes following liver transplantation, with no center-specific effects. Our findings support application of the down staging protocol on a broader scale. Patients with Child Pugh class B or C and AFP >1000 are unlikely to benefit from down staging. PMID- 29175530 TI - Increased tolerance of Beauveria bassiana and Metarhizium anisopliae conidia to high temperature provided by oil-based formulations. AB - The influence of the temperature of aqueous conidial sprays on conidial viability and virulence against Diatraea saccharalis was evaluated for pure conidia, rice + fungus (technical concentrates) and oil-based formulations of Beauveria bassiana s.s. and Metarhizium anisopliae s.s. under laboratory conditions. The fungal preparations were suspended in water and maintained at 26 degrees C, 36 degrees C and 46 degrees C for one, four and six hours. Conidial viability was determined by plating aliquots of each suspension onto PDA medium followed by incubation for 20-22 h and observing for viable conidia (germ tubes longer than diameter of conidia). Fungal virulence was determined by spraying suspensions onto third-instar larvae of D. saccharalis. In general, germination and virulence, particularly for unformulated conidia, were negatively affected by increases in water temperature and exposure time in suspension. However, the decrease in conidial viability in the oil-in-water emulsion was less than 7% for both species after 6 h of exposure at 36 degrees C, in contrast to reductions of 7-21% and 28-60% for the oil-free suspensions of B. bassiana and M. anisopliae, respectively. For the sprays of conidia in an oil-in-water emulsion previously exposed to elevated water temperatures for longer periods, the levels of insect mortality were higher than those of pure conidia or technical concentrates under identical conditions. Our results indicate that emulsifiable oil-based formulations can protect the conidia of both species of fungi from the adverse effects of high water temperatures before spraying in the field. PMID- 29175531 TI - Olfactory cues play a significant role in removing fungus from the body surface of Drosophila melanogaster. AB - Many insects and Dipterans in particular are known to spend considerable time grooming, but whether these behaviors actually are able to remove pathogenic fungal conidia is less clear. In this study, we examined whether grooming serves to protect flies by reducing the risk of fungal infection in Drosophila melanogaster. First, we confirmed that fungi were removed by grooming. Entomopathogenic, opportunistic, and plant pathogenic fungi were applied on the body surface of the flies. To estimate grooming efficiency, the number of removal conidia through grooming was quantified and we successfully demonstrated that flies remove fungal conidia from their body surfaces via grooming behavior. Second, the roles of gustatory and olfactory signals in fungus removal were examined. The wildtype fly Canton-S, the taste deficiency mutant poxn 70, and the olfactory deficiency mutant orco1 were used in the tests. Comparisons between Canton-S and poxn 70 flies indicated that gustatory signals do not have a significant role in fungal removal via grooming behavior in D. melanogaster. In contrast, the efficiency of conidia removal in orco1 flies was drastically decreased. Consequently, this study indicated that flies rely on mechanical stimulus for the induction of grooming and olfaction for more detailed removal. PMID- 29175532 TI - Mitochondrial dynamics tracking with iridium(III) complexes. AB - Since the discovery of mitochondrial dynamics, demand for dyes able to track this process has been a great. In contrast to static imaging, dynamic tracking requires superior photostability, low cytotoxicity and high resistance to the loss of mitochondrial membrane potential as well as appreciable tolerance to environmental changes. Recently, a variety of phosphorescent Ir(III) complexes have been found to localize in mitochondria and their applications as mitochondrial dynamics trackers have been assessed in cell monolayers, 3D MCSs and live animals. The examples presented here demonstrate that Ir(III) complexes constitute ideal candidates to meet the challenges of this topic. PMID- 29175533 TI - Large-scale evaluation of a rapid diagnostic test for diarrhea caused by enterotoxigenic Escherichia coli targeting the heat-labile toxin. AB - We standardized an immunochromatographic test (IC) for heat-labile toxin I (LT-I) detection using LT-I antibodies and a specific platform containing the apparatus for application, assembly and cutting. IC detected as little as 62.5ng/mL of purified LT-I toxin and presented 91% sensitivity, 99.5% specificity and 96.0% accuracy, thereby proving to be an excellent point-of-care test for the diagnosis of enterotoxigenic E. coli infection in low-income countries. PMID- 29175534 TI - A highly efficient Agrobacterium tumefaciens-mediated transformation system for the postharvest pathogen Penicillium digitatum using DsRed and GFP to visualize citrus host colonization. AB - Penicillium digitatum is a major postharvest pathogen of citrus crops. This fungus broadly spreads worldwide and causes green mold disease, which results in severe losses for citrus production. Understanding of the citrus infection by P. digitatum may help develop effective strategies for controlling this pathogen. In this study, we have characterized a virulent strain of P. digitatum isolated in Vietnam and established a highly efficient Agrobacterium tumefaciens-mediated transformation (ATMT) system for this fungal strain with two newly constructed binary vectors. These binary vectors harbor dominant selectable markers for hygromycin or nourseothricin resistance, and expression cassettes for the red fluorescent protein (DsRed) or the green fluorescent protein (GFP), respectively. Using the established ATMT system, the transformation efficiency of the Vietnamese strain could reach a very high yield of 1240+/-165 transformants per 106 spores. Interestingly, we found that GFP is much better than DsRed for in situ visualization of citrus fruit colonization by the fungus. Additionally, we showed that the transformation system can also be used to generate T-DNA insertion mutants for screening non-pathogenic or less virulent strains. Our work provides a new platform including a virulent tropical strain of P. digitatum, an optimized ATMT method and two newly constructed binary vectors for investigation of the postharvest pathogen. This platform will help develop strategies to dissect molecular mechanisms of host-pathogen interactions in more detail as well as to identify potential genes of pathogenicity by either insertional mutagenesis or gene disruption in this important pathogenic fungus. PMID- 29175535 TI - Application of prognostic scores in the STOPAH trial: Discriminant function is no longer the optimal scoring system in alcoholic hepatitis. AB - BACKGROUND & AIMS: 'Static' prognostic models in alcoholic hepatitis, using data from a single time point, include the discriminant function (DF), Glasgow alcoholic hepatitis score (GAHS), the age, serum bilirubin, international normalized ratio and serum creatinine (ABIC) score and the model of end-stage liver disease (MELD). 'Dynamic' scores, incorporating evolution of bilirubin at seven days, include the Lille score. The aim of this study was to assess these scores' performance in patients from the STOPAH trial. METHODS: Predictive performance of scores was assessed by area under the receiver operating curve (AUC). The effect of different therapeutic strategies upon survival was assessed by Kaplan-Meier analysis and tested using the log-rank test. RESULTS: A total of 1,068 patients were studied. The AUCs for the DF were significantly lower than for MELD, ABIC and GAHS for both 28- and 90-day outcomes: 90-day values were 0.670, 0.704, 0.726 and 0.713, respectively. 'Dynamic' scores and change in 'static' scores by Day 7 had similar AUCs. Patients with consistently low 'static' scores had low 28-day mortalities that were not improved with prednisolone (MELD <25: 8.6%; ABIC <6.71: 6.6%; GAHS <9: 5.9%). In patients with high 'static' scores without gastrointestinal bleeding or sepsis, prednisolone reduced 28-day mortality (MELD: 22.2% vs. 28.9%, p = 0.13; ABIC 14.6% vs. 21%, p = 0.02; GAHS 21% vs. 29.3%, p = 0.04). Overall mortality from treating all patients with a DF >=32 and Lille assessment (90-day mortality 26.8%) was greater than combining newer 'static' and 'dynamic' scores (90-day mortality: MELD/Lille 21.8%; ABIC/Lille 23.7%; GAHS/Lille 20.6%). CONCLUSION: MELD, ABIC and GAHS are superior to the DF in alcoholic hepatitis. Consistently low scores have a favourable outcome not improved with prednisolone. Combined baseline 'static' and Day 7 scores reduce the number of patients exposed to corticosteroids and improve 90-day outcome. LAY SUMMARY: Alcoholic hepatitis is a life-threatening condition. Several scores exist to determine the outcome of these patients as well as to identify those who may benefit from treatment. This study looked at the performance of existing scores in patients who had been recruited to the largest alcoholic hepatitis clinical trial: STOPAH. 'Static' scores are calculable at the start of assessment. The three newer static scores (ABIC, GAHS and MELD) were shown to be superior to the oldest score (DF). ABIC and GAHS could also identify patients who had a survival benefit 28 days after starting prednisolone treatment. 'Dynamic' scores relate to the change in disease over the first week of treatment. Combination of the 'static' scores 'with the 'dynamic' scores or change in 'static' scores allowed identification of patients who could benefit from prednisolone up to 90 days.

AB - In fact, a full sterilization of commercially-produced liquid nitrogen contaminated with different pathogens is not possible. The aim of this study was to compare the viability of human pronuclear oocytes subjected to cooling by direct submerging of open carrier in liquid nitrogen versus submerging in clean liquid air (aseptic system). One- and three-pronuclei stage embryos (n = 444) were cryopreserved by direct plunging into liquid nitrogen (vitrified) in ethylene glycol (15%), dimethylsulphoxide (15%) and 0.2M sucrose. Oocytes were exposed in 20, 33, 50 and 100% vitrification solution for 2, 1 and 1 min, and 30 50 s, respectively at room temperature. Then first part of oocytes (n = 225) were directly plunged into liquid nitrogen, and second part of oocytes (n = 219) into liquid air. Oocytes were thawed rapidly at a speed of 20,000 degrees C/min and then subsequently were placed into a graded series of sucrose solutions (0.5, 0.25, 0.12 and 0.06M) at 2.5 min intervals and cultured in vitro for 3 days. In both groups, the rate of high-quality embryos (Grade 6A: 6 blastomeres, no fragmentation; Grade 8A: 8 blastomeres, no fragmentation; Grade 8A compacting: 8 blastomeres, beginning of compacting) was noted. The rates of high-quality embryos developed from one-pronuclear oocytes vitrified by cooling in liquid nitrogen and liquid air were: 39.4% +/- 0.6 and 38.7% +/- 0.8, respectively (P > 0.1). These rates for three-pronuclear oocytes were: 45.8 +/- 0.8% and 52.0 +/- 0.7%, respectively (P < 0.05). In conclusion, vitrification by direct submerging of oocytes in clean liquid air (aseptic system) is a good alternative for using of not sterile liquid nitrogen. PMID- 29175540 TI - The Effect of Family Assistance to Wake Children with Monosymptomatic Enuresis in Alarm Therapy: A Pilot Study. AB - PURPOSE: Alarm therapy is widely used as first line treatment for nocturnal enuresis. However, some children do not wake when nocturnal urination activates the alarm. It is currently unclear whether waking the child when the alarm is activated improves the efficacy of alarm therapy. In this study we investigated the efficacy of alarm therapy for nocturnal enuresis when children do not wake in response to the sound and their parents do not wake them. MATERIALS AND METHODS: Detailed information regarding incontinence was retrospectively obtained from 78 of 112 patients who underwent alarm therapy between 2006 and 2016, and completed a questionnaire and a 14-day bladder diary. The enrolled patients were divided into 2 groups. In the family assisted group (44) the children were awakened by family members when the alarm sounded. In the alarm control group (34) the children were self-responsible for waking to the alarm. The groups were compared to investigate differences at 16 weeks after alarm therapy began. The efficacy rate was calculated using the International Children's Continence Society criteria. RESULTS: The efficacy was similar between the groups. Full response and partial response were observed in 36.4% and 20.5% of patients in the family assisted group, and 26.5% and 29.4% of patients in the alarm control group (p = 1.00), respectively. There was no significant difference in the percentage of children who woke spontaneously to the alarm in the 2 groups (56.7% and 64.0%, respectively). CONCLUSIONS: Family assisted alarm therapy and self-responsible alarm therapy are equally efficacious in the treatment of childhood nocturnal enuresis. PMID- 29175541 TI - A Randomized Comparative Study Evaluating Various Cough Stress Tests and 24-Hour Pad Test with Urodynamics in the Diagnosis of Stress Urinary Incontinence. AB - PURPOSE: The cough stress test is a common and accepted tool to evaluate stress urinary incontinence but there is no agreement on how the test should be performed. We assessed the diagnostic ability of different cough stress tests performed when varying patient position and bladder volume using urodynamic stress urinary incontinence as the gold standard. The 24-hour pad test was also evaluated. MATERIALS AND METHODS: We recruited women who presented to specialty outpatient clinics with the complaint of urinary incontinence and who were recommended to undergo urodynamic testing. A total of 140 patients were randomized to 4 cough stress test groups, including group 1-a comfortably full bladder, group 2-an empty bladder, group 3- a bladder infused with 200 cc saline and group 4-a bladder filled to half functional capacity. The sequence of standing and sitting was randomly assigned. The groups were compared by 1-way ANOVA or the generalized Fisher exact test. The kappa statistic was used to evaluate agreement between the sitting and standing positions. The 95% CIs of sensitivity and specificity were calculated using the Wilson method. ROC analysis was done to evaluate the performance of the 24-hour pad test. RESULTS: The cough stress test performed with a bladder filled to half functional capacity was the best performing test with 83% sensitivity and 90% specificity. There was no statistically significant evidence that the sensitivity or specificity of 1 cough stress test differed from that of the others. The pad test had no significant predictive ability to diagnose urodynamic stress urinary incontinence (AUC 0.60, p = 0.08). CONCLUSIONS: Cough stress tests were accurate to diagnose urodynamic stress urinary incontinence. The 24-hour pad test was not predictive of urodynamic stress urinary incontinence and not helpful when used in conjunction with the cough stress test. PMID- 29175538 TI - White matter structural connectivity and episodic memory in early childhood. AB - Episodic memory undergoes dramatic improvement in early childhood; the reason for this is poorly understood. In adults, episodic memory relies on a distributed neural network. Key brain regions that supporting these processes include the hippocampus, portions of the parietal cortex, and portions of prefrontal cortex, each of which shows different developmental profiles. Here we asked whether developmental differences in the axonal pathways connecting these regions may account for the robust gains in episodic memory in young children. Using diffusion weighted imaging, we examined whether white matter connectivity between brain regions implicated in episodic memory differed with age, and were associated with memory performance differences in 4- and 6-year-old children. Results revealed that white matter connecting the hippocampus to the inferior parietal lobule significantly predicted children's performance on episodic memory tasks. In contrast, variation in the white matter connecting the hippocampus to the medial prefrontal cortex did not relate to memory performance. These findings suggest that structural connectivity between the hippocampus and lateral parietal regions is relevant to the development of episodic memory. PMID- 29175539 TI - Intact perceptual ability, but impaired familiarity judgment, after neonatal perirhinal lesions in rhesus macaques. AB - The perirhinal cortex is known to support high-level perceptual abilities as well as familiarity judgments that may affect recognition memory. We tested whether poor perceptual abilities or a loss of familiarity judgment contributed to the recognition memory impairments reported earlier in monkeys with PRh lesions received in infancy (Neo-PRh) (Weiss and Bachevalier, 2016; Zeamer et al., 2015). Perceptual abilities were assessed using a version of the Visual Paired Comparison task with black&white (B&W) stimuli, and familiarity judgments were assessed using the Constant Negative task requiring repeated familiarization exposures. Adult monkeys with Neo-PRh lesions were able to recognize B&W stimuli after short delays, suggesting that their perceptual abilities were within the range of control animals. However, the same Neo-PRh monkeys were slower to acquire the Constant Negative task, requiring more exposures to objects before judging them as familiar compared to control animals. Taken together, the data help to account for the differential patterns of functional compensation on previously reported recognition tasks following neonatal versus adult-onset PRh lesions, and provide further support to the view that the PRh is involved in familiarity processes. PMID- 29175542 TI - Defining a Cohort that May Not Require Repeat Prostate Biopsy Based on PCA3 Score and Magnetic Resonance Imaging: The Dual Negative Effect. AB - PURPOSE: Prostate cancer over diagnosis and overtreatment are concerns for clinicians and policy makers. Multiparametric magnetic resonance imaging and the PCA3 (prostate cancer antigen 3) urine test select for clinically significant cases. We explored how well the tests performed together with previous biopsies. MATERIALS AND METHODS: In accordance with ethics committee approval we collected clinicopathological data on all patients in whom a PCA3 test was done from January 2011 to June 2016. This included patients on active surveillance for low risk prostate cancer and those without prostate cancer who had previous negative biopsies and suspicion of occult disease. We explored whether age, prostate specific antigen, PCA3 score, multiparametric magnetic resonance imaging, digital rectal examination, family history and prostate size would predict clinically significant prostate cancer on repeat biopsy. The negative predictive value of multiparametric magnetic resonance imaging and PCA3 score was calculated. RESULTS: A total of 470 patients were included in study. The PCA3 score was abnormal at 35 or greater in 32.5% of cases. In the multivariate model including 154 men only age (OR 1.08, 95% CI 1.01-1.16), multiparametric magnetic resonance imaging PI-RADSTM (Prostate Imaging-Reporting and Data System) score 4 (OR 16.6, 95% CI 3.9-70.0) or 5 (OR 28.3, 95% CI 5.7-138) and PCA3 score (OR 2.9, 95% CI 1.0-8.8) predicted clinically significant cancer on biopsy. No patient with negative multiparametric magnetic resonance imaging and a normal PCA3 score had clinically significant prostate cancer on biopsy for a negative predictive value of 100% (p <0.0001). CONCLUSIONS: In patients with dual negative tests (multiparametric magnetic resonance imaging and PCA3 score) clinically significant prostate cancer was never found on biopsy, which may be unnecessary in this group. This study was limited by its retrospective design, selection bias and lack of cost-effectiveness data. PMID- 29175543 TI - High mobility group box-1 (HMGB1) is increased in injured mouse spinal cord and can elicit neurotoxic inflammation. AB - Inflammation is a ubiquitous but poorly understood consequence of spinal cord injury (SCI). The mechanisms controlling this response are unclear but culminate in the sequential activation of resident and recruited immune cells. Collectively, these cells can exert divergent effects on cell survival and tissue repair. HMGB1 is a ubiquitously expressed DNA binding protein and also a potent inflammatory stimulus. Necrotic cells release HGMB1, but HMGB1 also is actively secreted by inflammatory macrophages. A goal of this study was to quantify spatio temporal patterns of cellular HMGB1 expression in a controlled mouse model of experimental SCI then determine the effects of HMGB1 on post-SCI neuroinflammation and recovery of function. We documented SCI-induced changes in nuclear and cytoplasmic distribution of HMGB1 in various cell types after SCI. The data reveal a time-dependent increase in HMGB1 mRNA and protein with protein reaching maximal levels 24-72 h post-injury then declining toward baseline 14-28 days post-SCI. Although most cells expressed nuclear HMGB1, reduced nuclear labeling with increased cytoplasmic expression was found in a subset of CNS macrophages suggesting that those cells begin to secrete HMGB1 at the injury site. In vitro data indicate that extracelluar HMGB1 helps promote the development of macrophages with a neurotoxic phenotype. The ability of HMGB1 to elicit neurotoxic macrophage functions was confirmed in vivo; 72 h after injecting 500 ng of recombinant HMGB1 into intact spinal cord ventral horn, inflammatory CNS macrophages co-localized with focal areas of neuronal killing. However, attempts to confer neuroprotection after SCI by blocking HMGB1 with a neutralizing antibody were unsuccessful. Collectively, these data implicate HMGB1 as a novel regulator of post-SCI inflammation and suggest that inhibition of HMGB1 could be a novel therapeutic target after SCI. Future studies will need to identify better methods to deliver optimal concentrations of HMGB1 antagonists to the injured spinal cord. PMID- 29175544 TI - Comparative systemic analysis of the cellular growth of leaves and roots in controlled conditions. AB - The comparative cytological analysis of the leaf/root growth of Lolium multiflorum has been performed. It revealed differences of the mentioned above/under-ground organs that express the whole plant's polarity. To perform accurate and simultaneous growth comparison a climatic-hydroponics system has been implemented. A sharp increase in the epidermis cell length of the leaf meristem has been detected for the first time. It allows the proposal of a new way to demarcate the boundary of the meristem and suggests a lengthed leaf meristem, that is 4 times longer than the root meristem. As the cell cycle duration in leaves and roots is similar, the prolonged leaf meristem and a higher leaf growth rate could be determined by the longer life span of cells in meristem, resulting in more cell cycles. The prolonged meristem provides a significantly higher leaf growth rate, ensuring a functional balance with roots. The elongation zone of the roots is significantly shorter than in leaves, which is caused by the larger relative root elongation rate and the slower meristemic root growth rate. The novelty formulated, i.e., the prolonged leaf meristem, opens theoretical perspectives in longitudinal zonation, in finding molecular markers and provides practical significance for the biology of productivity. PMID- 29175545 TI - In vivo cytological and chemical analysis of Casparian strips using stimulated Raman scattering microscopy. AB - The Casparian strip, a barrier to the apoplastic movement of solutes from the cortex to the stele, is essential for the exclusion of salts, selective nutrient uptake, and many other processes. To date, extensive studies have focused on the physiological functions of endodermal Casparian strips. However, the chemical deposition nature of Casparian strips, as well as its relevance with respect to diffusion barrier functions, remains to be further elucidated. Here, we revealed three developmental stages of Casparian strips in maize primary roots using a traditional fluorescent staining method. Apoplastic permeability tests demonstrated that the barrier function of Casparian strips is largely related to their developmental stage and the pattern of lignin and suberin deposits. Fourier transform infrared (FTIR) analysis showed that the Casparian strips from the roots exhibited significant absorption bands characteristic of lignin and suberin, implying that the Casparian strips in maize primary roots consist largely of lignin and suberin. Furthermore, we developed a new method for label free, in vivo structural, and biochemical analysis of Casparian strips based on stimulated Raman scattering (SRS) microscopy. Using SRS microscopy, we found that lignin and suberin accumulate simultaneously during the Casparian strip formation process. Based on these results, we propose a potential application of SRS for the chemical composition analysis of plant Casparian strips in situ.

AB - Zero echo time magnetic resonance imaging (ZTE MRI) at 9.4T was used to assess the local distribution of water in dolomite rocks under different saturation conditions. The results were compared with the industry standard Single Point Imaging (SPI) at 0.6T. 3D maps of the local amount of water saturating heterogeneous rock were obtained from the imaging data, and correlated with the corresponding structural images from high resolution micro-CT (MUCT). The method can be applicable in the investigation of spatial kinetics of water saturation processes in porous, heterogeneous rocks where imaging methods based on spin echo, such as RARE, have failed due to short T2, while SPI is often impractical due to its long acquisition time. PMID- 29175546 TI - How many pygmy marmoset (Cebuella Gray, 1870) species are there? A taxonomic re appraisal based on new molecular evidence. AB - The pygmy marmoset, Cebuella pygmaea, the smallest of the New World monkeys, has one of the largest geographical distributions of the Amazonian primates. Two forms have been recognized: Cebuella pygmaea pygmaea (Spix, 1823), and C. p. niveiventris Lonnberg, 1940. In this study, we investigated if the separation of pygmy marmosets into these two clades can be corroborated by molecular data. We also examine and compare coloration of the pelage in light of the new molecular results. We analyzed the mtDNA cytochrome b gene and, for the first time for any Neotropical primate, we used a reduced representation genome sequencing approach (ddRADseq) to obtain data for recently collected, geographically representative samples from the Rio Japura, a northern tributary of the Rio Solimoes and from the Javari, Jutai, Jurua, Madeira and Purus river basins, all tributaries south of the Solimoes. We estimated phylogenies and diversification times under both maximum likelihood and Bayesian inference criteria. Our analysis showed two highly supported clades, with intraclade divergences much smaller than interclade divergences, indicating two species of Cebuella: one from the Rio Japura and one to the south of Solimoes. The interpretation of our results in light of the current taxonomy is not trivial however. Lonnberg stated that the type of Spix's pygmy marmoset (type locality 'near Tabatinga') was obtained from the south of the Solimoes, and his description of the distinct niveiventris from Lago Ipixuna, south of the Solimoes and several hundred kilometres east of Tabatinga, was based on a comparison with specimens that he determined as typical pygmaea that were from the upper Rio Jurua (south of the Solimoes). As such it remains uncertain whether the name pygmaea should be applicable to the pygmy marmosets north of the Rio Solimoes (Tabatinga type locality) or south (near Tabatinga but across the Solimoes). Finally, our analysis of pelage coloration revealed three phenotypic forms: (1) south of the Rio Solimoes, (2) Eirunepe-Acre, upper Jurua basin; and (3) Japura. More samples from both sides of Solimoes in the region of Tabatinga will be necessary to ascertain the exact type locality for Spix's pygmaea and to resolve the current uncertainties surrounding pygmy marmoset taxonomy.

AB - We proposed an unsupervised hybrid method - Intelligent Word Embedding (IWE) that combines neural embedding method with a semantic dictionary mapping technique for creating a dense vector representation of unstructured radiology reports. We applied IWE to generate embedding of chest CT radiology reports from two healthcare organizations and utilized the vector representations to semi-automate report categorization based on clinically relevant categorization related to the diagnosis of pulmonary embolism (PE). We benchmark the performance against a state-of-the-art rule-based tool, PeFinder and out-of-the-box word2vec. On the Stanford test set, the IWE model achieved average F1 score 0.97, whereas the PeFinder scored 0.9 and the original word2vec scored 0.94. On UPMC dataset, the IWE model's average F1 score was 0.94, when the PeFinder scored 0.92 and word2vec scored 0.85. The IWE model had lowest generalization error with highest F1 scores. Of particular interest, the IWE model (trained on the Stanford dataset) outperformed PeFinder on the UPMC dataset which was used originally to tailor the PeFinder model. PMID- 29175550 TI - Molecular modeling study on resistance of WT/D473H SMO to antagonists LDE-225 and LEQ-506. AB - The smoothened (SMO) receptor, an essential signal transducer in the Hedgehog pathway, was targeted with antagonists to suppress the tumor. It is interesting that SMO D473H mutation confers resistance on inhibitor LDE-225 rather than LEQ 506. In this paper, the binding modes of them against the wild type and mutant SMO receptors were identified to gain insights into the resistant and non resistant factors, based on a comprehensive protocol involving molecular docking, molecular dynamic simulations, free energy calculation and decomposition. A comparison of resistant LDE-225 and non-resistant LEQ-506 indicates that the volume of the binding cavity decreases seriously in the mutant complex with resistant LDE-225. In addition, the D473H mutation disrupts the hydrogen bond network with residues R400 and Q477, which results in the TM6 conformation inward. Owing to the absence of the hydrogen bond, residues R400 and Q477 make weak contributions to LDE-225. However, the D473H mutation along with TM6 conformational change has no effect on non-resistant LEQ-506. Finally, the resistance ascribes to adverse interaction between the greater polarity of mutant residue H473 and the nonpolar phenmethyl of LDE-225. The elaborate insights into structural and energetic mechanism of drug resistance provide an effective strategy to design rationally non-resistant antagonists. PMID- 29175549 TI - Integrated analytical assets aid botanical authenticity and adulteration management. AB - This article reviews and develops a perspective for the meaning of authenticity in the context of quality assessment of botanical materials and the challenges associated with discerning adulterations vs. contaminations vs. impurities. Authentic botanicals are by definition non-adulterated, a mutually exclusive relationship that is confirmed through the application of a multilayered set of analytical methods designed to validate the (chemo)taxonomic identity of a botanical and certify that it is devoid of any adulteration. In practice, the ever-increasing sophistication in the process of intentional adulteration, as well as the growing number of botanicals entering the market, altogether necessitate a constant adaptation and reinforcement of authentication methods with new approaches, especially new technologies. This article summarizes the set of analytical methods - classical and contemporary - that can be employed in the authentication of botanicals. Particular emphasis is placed on the application of untargeted metabolomics and chemometrics. An NMR-based untargeted metabolomic model is proposed as a rapid, systematic, and complementary screening for the discrimination of authentic vs. potentially adulterated botanicals. Such analytical model can help advance the evaluation of botanical integrity in natural product research.

AB - Gellan gum microparticles coated with colon-specific films based on retrograded starch and pectin was developed for enhancing the oral release of insulin (INS). The system developed promoted an impressive protection of INS (80%) after 120 min of incubation with trypsin and alpha-chymotrypsin, while only 3% of free INS remained intact after the same time, possibility due to the calcium chelating activity of the polymers in inhibiting the proteolytic activity. In vitro INS release in media simulating the gastrointestinal portions revealed a pH-dependent behavior, as well as the significance of the coating in lowering the release rates in relation to their counterparts. The permeability of INS on Caco-2 cells monolayers and excised rat intestine were significantly improved, mainly due to the influence of the anionic polymers on tight junctions opening, along with the excellent mucoadhesive properties of the gellan gum. All these features together contributed greatly to the hypoglycemic effect observed after the oral administration of the INS-loaded MP in diabetic rats, with reduction of up to 51% of blood glucose levels. The important findings of this work should contribute to the advances about the search of alternatives for oral administration of INS. PMID- 29175552 TI - Long pentraxin 3: A novel multifaceted player in cancer. AB - Since its discovery in 1992, long pentraxin 3 (PTX3) has been characterized as soluble patter recognition receptor, a key player of the innate immunity arm with non-redundant functions in pathogen recognition and inflammatory responses. As a component of the extra-cellular matrix milieu, PTX3 has been implicated also in wound healing/tissue remodeling, cardiovascular diseases, fertility, and infectious diseases. Consequently, PTX3 levels in biological fluids have been proposed as a fluid-phase biomarker in different pathological conditions. In the last decade, experimental evidences have shown that PTX3 may exert a significant impact also on different aspects of cancer biology, including tumor onset, angiogenesis, metastatic dissemination and immune-modulation. However, it remains unclear whether PTX3 acts as a good cop or bad cop in cancer. In this review, we will summarize and discuss the scientific literature data focusing on the role of PTX3 in experimental and human tumors, including its putative translational implications. PMID- 29175554 TI - Determination of ZSTK474, a novel Pan PI3K inhibitor in mouse plasma by LC-MS/MS and its application to Pharmacokinetics. AB - ZSTK474, a promising novel anticancer molecule derived from s-triazine, found to have antitumor activities against different cancer cell lines. However, neither LCMS method nor pharmacokinetics of ZSTK474 has been reported till now. A sensitive, simple, short and specific liquid chromatography tandem mass spectrometry (LCMS/MS) method was developed for the quantification of ZSTK474 in mouse plasma accordance with the US Food and Drug Administration guidelines. Extraction of drug molecule was carried out using protein precipitation. Chromatographic analyte separation was achieved on Atlantis dC18 (4.6*50mm, 3MUm). Composition of isocratic mobile phase consists of 90% acetonitrile and 0.2% formic acid, at 0.7mL/min flow rate, having short 2.5min run time. Method development was validated and found to be linear over a dynamic range between 1.9 1000ng/mL; having a correlation coefficient (r 2)>=0.9978. The analyte was found to be stable under short and long term storage conditions. LCMS/MS method developed was validated and found to be selective, reproducible, precise and accurate to quantify ZSTK474 in plasma samples, and first time successfully applied to pharmacokinetic studies. Pharmacokinetic data showed fast absorption attaining Cmax at 0.25h and half life (t1/2) 5.18h after oral administration of ZSTK474 at 20mg/kg in mouse. PMID- 29175555 TI - Pharmacokinetics of doxorubicin in glioblastoma multiforme following ultrasound Induced blood-brain barrier disruption as determined by microdialysis. AB - The goal of this study was to investigate the in vivo extracellular kinetics of doxorubicin (Dox) in glioblastoma multiforme (GBM)-bearing mice following focused ultrasound (FUS)-induced blood-brain barrier (BBB) disruption using microdialysis. An intracranial brain tumor model in NOD-scid mice using human brain GBM 8401 cells was used in this study. Prior to each sonication, simultaneous intravenous administration of Dox and microbubbles, and the Dox concentration in the brains was quantified by high performance liquid chromatography (HPLC). Drug administration with sonication elevated the tumor-to normal brain Dox ratio of the target tumors by about 2.35-fold compared with the control tumors. The mean peak concentration of Dox in the sonicated GBM dialysate was 10 times greater than without sonication, and the area under the concentration-time curve was 3.3 times greater. This study demonstrates that intracerebral microdialysis is an effective means of evaluating real-time target BBB transport profiles and offers the possibility of investigating the pharmacokinetics of drug delivery in the sonicated brain. PMID- 29175556 TI - Rapid and simple procedure for the determination of cathinones, amphetamine-like stimulants and other new psychoactive substances in blood and urine by GC-MS. AB - In the last few years an increasing number of new psychoactive substances (NPS), with different chemical structures (of which 37% are stimulants), have been released into the illicit drug market. Their detection and identification in biological samples is hence of great concern. The aim of this work was to develop a high-throughput and rapid method for the determination of different classes of stimulants (amphetamine-type stimulants, cathinones, phenethylamines and ketamine analogues) from blood and urine samples using GC-MS. The proposed method allows the almost simultaneous derivatization and extraction of analytes from biological samples in a very short time, by using hexyl chloroformate as derivatization agent. The extraction of analytes was performed by Dispersive Liquid Liquid Microextraction (DLLME), a very rapid, cheap and efficient extraction technique that employs microliter amounts of organic solvents. The chromatographic method allowed for the separation of 26 stimulants including positional isomers (3-MMC and 4-MMC). The method was validated on urine and blood samples with the ability to detect and quantify all analytes with satisfactory limits of detection (LODs) ranging between 1 and 10ng/mL, limits of quantification (LOQs) between 2 and 50ng/mL, selectivity and linearity (5-1000ng/mL). The method was then applied to real samples from forensic cases, demonstrating its suitability for the screening of a wide number of stimulants in biological specimens. PMID- 29175557 TI - Meniscal repair: Technique. AB - Meniscal repair aims to achieve meniscal healing, avoiding the adverse effects of meniscectomy. Longitudinal vertical tears in a vascularized area are the reference indication. The technique generally uses hybrid all-inside implants. The outside-in technique has other indications in more anterior tears. Healing has been demonstrated on CT-arthrography and arthroscopy. Specific techniques have been developed for other pathological situations. Posterior meniscosynovial lesions in a context of chronic anterior laxity are identified by exploration of the posterior compartment, and fixed by all-inside hook suture. Horizontal lesions in young athletes can be treated by open meniscal suture. Radial tears, when deep, can be repaired. Root tears, when traumatic, can be treated by transosseous pullout reinsertion. PMID- 29175553 TI - The key role of extracellular vesicles in the metastatic process. AB - Extracellular vesicles (EVs), including exosomes, have a key role in the paracrine communication between organs and compartments. EVs shuttle virtually all types of biomolecules such as proteins, lipids, nucleic acids, metabolites and even pharmacological compounds. Their ability to transfer their biomolecular cargo into target cells enables EVs to play a key role in intercellular communication that can regulate cellular functions such as proliferation, apoptosis and migration. This has led to the emergence of EVs as a key player in tumor growth and metastasis through the formation of "tumor niches" in target organs. Recent data have also been shown that EVs may transform the microenvironment of primary tumors thus favoring the selection of cancer cells with a metastatic behavior. The release of EVs from resident non-malignant cells may contribute to the metastatic processes as well. However, cancer EVs may induce malignant transformation in resident mesenchymal stem cells, suggesting that the metastatic process is not exclusively due to circulating tumor cells. In this review, we outline and discuss evidence-based roles of EVs in actively regulating multiple steps of the metastatic process and how we can leverage EVs to impair metastasis. PMID- 29175558 TI - A complex phenotype in a family with a pathogenic SOX3 missense variant. AB - Duplications and deletions of Xq26-27 including SOX3 (Xq27.1) have been associated with X-linked mental retardation and isolated growth hormone deficiency (OMIM 300123) or X-linked panhypopituitarism (OMIM 312000). Yet, pathogenic point mutations seem to be extremely rare. We report a family with three affected males with several clinical features including mild intellectual disability, microphthalmia, coloboma, hypopituitarism, facial dysmorphology and dental anomalies, including microcephaly, retrognathia and a solitary median maxillary central incisor amongst other features. Using Whole Exome Sequencing a missense variant in SOX3, NM_005634.2:c.449C>A; p.(Ser150Tyr) was identified. Segregation analysis in the family demonstrated that the variant was inherited through healthy females with its origin in the maternal grandmother showing germline mosaicism. Thus, we report one of the first cases of a pathogenic variant in SOX3 and germline mosaicism of this variant. PMID- 29175559 TI - Desmosterolosis presenting with multiple congenital anomalies. AB - Desmosterolosis is a rare multiple congenital anomaly syndrome caused by a defect in the enzyme 3-beta-hydroxysterol delta-24-reductase (DHCR24) in the cholesterol biosynthesis pathway. Defects in this enzyme cause increased level of the cholesterol precursor desmosterol while disrupting development of cholesterol, impacting embryogenesis. A total of 9 cases of desmosterolosis have been reported to date. We report a 20-month-old male from consanguineous parents with multiple congenital anomalies including corpus callosum hypoplasia, facial dysmorphism, cleft palate, pectus deformity, short and wide neck and distal contractures. On analysis of the regions of homozygosity found by microarray, we identified DHCR24 as a candidate gene. Sterol quantitation showed a desmosterol level of 162 MUg/mL (nl: 0.82 +/- 0.48). Genetic testing confirmed the diagnosis with a homozygous likely pathogenic mutation (p.Glu191Lys) in the DHCR24 gene. Our case expands the known diagnostic spectrum for Desmosterolosis. We suggest considering Desmosterolosis in the differential diagnosis of patients who present with concurrent agenesis of the corpus callosum with white matter atrophy and ventriculomegaly, retromicrognathia with or without cleft palate, hand contractures, and delay of growth and development. Children of consanguineous mattings may be at higher risk for rare recessive disorders and testing for cholesterol synthesis defect should be a consideration for affected children. Initial evaluation can be performed using sterol quantitation, followed by genetic testing.

Acta 1837(6) (2014) 811-824 DOI: 10.1016/j.bbabio.2014.01.020]. PMID- 29175562 TI - Utilisation and polypharmacy aspects of antiepileptic drugs in elderly versus younger patients with epilepsy: A pharmacoepidemiological study of CNS-active drugs in Norway, 2004-2015. AB - BACKGROUND AND PURPOSE: Many patients with epilepsy use antiepileptic drugs (AEDs) in combination. The elderly is a vulnerable group regarding polypharmacy. The purpose of this study was to investigate changes in utilisation of AEDs, and the extent of polypharmacy with other CNS-active drugs in elderly versus younger patients in Norway. METHODS: This pharmacoepidemiological study included all prescriptions of antiepileptic, antidepressant and antipsychotic drugs from Norwegian pharmacies in the Norwegian Prescription Database (NorPD) (2004-2015). Variables included number of patients, utilisation in defined daily doses, age, gender, and diagnosis specific reimbursement codes for AEDs. RESULTS: The use of AEDs has increased in all age groups in this population-based study in Norway. In the elderly, AEDs used in neuropathic pain (mainly gabapentin and pregabalin) have increased more than 10-fold (from 0.7 to 9.6 DDDs/1000 elderly/day, 2004 2015), while the prevalence of users is four times more than in younger patients. Polypharmacy between antiepileptic, antidepressant and antipsychotic drugs occurred in 35% of elderly and 38% of younger patients with epilepsy. The use of enzyme-inducers was common, and occurred more often in elderly patients. A total of 42 different interactions that may have clinical implications were identified among these drugs. CONCLUSION: The use of AEDs in elderly compared to younger patients is increasing, especially in neuropathic pain. Polypharmacy with antiepileptic, antidepressant and/or antipsychotic drugs was documented in more than one third of the patients. Awareness of increased drug utilisation, polypharmacy with potential drug interactions, and focus on elderly patients are important for increased patient safety. PMID- 29175563 TI - Do neurologists around the world agree when diagnosing epilepsy? - Results of an international EpiNet study. AB - OBJECTIVE: Previous studies have shown moderate agreement between physicians when diagnosing epilepsy, but have included small numbers. The EpiNet study group was established to undertake multicentre clinical trials in epilepsy. Before commencing trials, we wanted to determine levels of agreement between physicians from different countries and different health systems when diagnosing epilepsy, specific seizure types and etiologies. METHODS: 30 Case scenarios describing six children and 24 adults with paroxysmal events (21 epileptic seizures, nine non epileptic attacks) were presented to physicians with an interest in epilepsy. Physicians were asked how likely was a diagnosis of epilepsy; if seizures were generalised or focal; and the likely etiology. For 23 cases, clinical information was presented in Step 1, and investigations in Step 2. RESULTS: 189 Participants from 36 countries completed the 30 cases. Levels of agreement were determined for 154 participants who provided details regarding their clinical experience. There was substantial agreement for diagnosis of epilepsy (kappa=0.61); agreement was fair to moderate for seizure type(s) (kappa=0.40) and etiology (kappa=0.41). For 23 cases with two steps, agreement increased from step 1 to step 2 for diagnosis of epilepsy (kappa 0.56-0.70), seizure type(s) (kappa 0.38-0.52), and etiology (kappa 0.38-0.47). Agreement was better for 53 epileptologists (diagnosis of epilepsy, kappa=0.66) than 56 neurologists with a special interest in epilepsy (kappa=0.58). Levels of agreement differed slightly between physicians practicing in different parts of the world, between child and adult neurologists, and according to one's experience with epilepsy. CONCLUSION: Although there is substantial agreement when epileptologists diagnose epilepsy, there is less agreement for diagnoses of seizure types and etiology. Further education of physicians regarding semiology of different seizure types is required. Differences in approach to diagnosis, both between physicians and between countries, could impact negatively on clinical trials of anti-epileptic drugs. PMID- 29175564 TI - Shear horizontal wave propagation in a periodic stubbed plate and its application in rainbow trapping. AB - The high-order waveguide modal theory, usually used in electromagnetics and acoustics, is adopted to investigate the propagation properties of shear horizontal waves in a periodic stubbed plate. Beyond the sub-wavelength regime, higher-order modes are included to calculate the exact band structures caused by the stubs. Theoretical solutions are obtained in a closed form, in which both the dynamic governing equations and the boundary conditions are strictly satisfied. It is shown that the proposed modelling approach exhibits good convergence and accuracy, in agreement with results obtained from the finite element method. After a systematic investigation on the influence of the stub on the evolution of the band structures, the so-called rainbow trapping phenomenon of SH waves is revealed and explored in a graded stubbed plate with monotonously increasing height or width of the stubs, featuring an obvious reduction of the group velocity and blocking of the wave propagation at different locations for SH waves of different frequencies. The proposed model is expected to provide a useful theoretical tool for the physical mechanism exploration, structural design and eventually system optimization to guide various engineering applications of SH waves. PMID- 29175565 TI - 3D ultrasound imaging in frequency domain based on concepts of array beam and synthetic aperture. AB - The high frame rate (HFR) imaging method has the ability to achieve a high frame rate. In this method, only one transmission is required to construct a frame of image. In our previous work, using a moved one-dimensional (1D) array transducer, a three-dimensional (3D) ultrasound imaging method in frequency domain was developed. This imaging method was designed based on the concepts of array beam and synthetic aperture, which can simplify the two-dimensional (2D) array transducer. In this paper, based on array beam and synthetic aperture, the HFR imaging method is demonstrated from a novel view. From this view, the relationship between the HFR imaging method and synthetic aperture is established with the weighting function of array beam. Besides, the HFR imaging method, the imaging method with a moved 1D array transducer, and the synthetic aperture imaging method with a moved single element transducer are unified in the same analytical method with different weighting functions. The same frequency domain signal processing flow can be applied to these imaging methods. Comparisons to these imaging methods are implemented with simulations. Simulation results show that, in the imaging depth of 45 mm, the resolutions calculated as the total width of the -6 dB main lobe in x-direction are 1.099 mm, 1.056 mm and 0.596 mm for the methods with 1D transducer, 2D transducer and the single element transducer, respectively. The resolution in y-direction is 1.054 mm for the methods with 2D transducer, and 0.565 mm, 0.593 mm for the 1D and single element transducers, respectively. The resolutions in z-direction are 0.493 mm, 0.451 mm and 0.452 mm for the 2D, 1D and single element transducers, respectively. The resolution in the moved-direction is improved with a moved transducer, but the contrast of the image is decreased. PMID- 29175566 TI - Quality Enhancement of Ultrasonic TOFD Signals from Carbon Steel Weld Pad with Notches. AB - Welding is an integral part of component fabrication in industry. Even though the science and art of welding are more than 100 years old, defects continue to occur during welding. Codes of practice require that the welds be tested and evaluated. Conventionally ultrasonic testing has been widely applied in industry for the detection and evaluation of the flaws/defects in the weldments. With advances in sensor and signal analysis technologies, the last two decades have seen extensive developments in the field of ultrasonic testing. We have advanced techniques such as Time of Flight Diffraction (TOFD) which has better probability of detection for linear defects. A major irritant during the application of TOFD, especially for the testing of carbon steel weldments, is the presence of noise. A variety of approaches has been used internationally for the suppression of such noise and each has its own merits and demerits. This paper focuses on a method of enhancing the TOFD A-scan signals in carbon steel weldments by suppressing the noise from them using the discrete wavelet transform (DWT). The analysis clearly indicates that the DWT gives better signal-to-noise ratio improvement using higher-order wavelet filters with 4-level DWT decomposition. However the computational cost of this signal enhancement depends on the wavelet filter chosen along with the chosen level of DWT decomposition. PMID- 29175567 TI - Flat-Detector Computed Tomography for Evaluation of Intracerebral Vasculature for Planning of Stereoelectroencephalography Electrode Implantation. AB - OBJECTIVE: Stereoelectroencephalography (sEEG) requires extensive preoperative planning to optimize placement of electrodes and limit the potential for complications. Flat-detector computed tomography (FD-CT) has previously been used for perioperative vascular imaging to guide the treatment of vascular lesions. This imaging modality provides a detailed depiction of cerebrovascular and bony cranial anatomy, which can be used to guide intracranial electrode implantation. We have developed a novel method to improve preoperative planning for sEEG electrode implantation and limit the potential for postoperative complications by using FD-CT imaging merged with preoperative magnetic resonance imaging (MRI). METHODS: All patients underwent preoperative FD-CT with selective intra-arterial iodinated contrast dye injection through the late arterial and capillary phases for evaluation of cerebrovascular anatomy. These results were merged with thin cut MRI for trajectory planning of intracranial sEEG electrodes. All patients underwent routine CT and MRI after electrode placement. RESULTS: 39 patients have undergone sEEG implantation according to this protocol, with a total of 541 electrodes placed. Additionally, 25 (64.1%) patients underwent implantation of 70 oblique insular electrodes. There were no clinically significant complications after the implantations. Thirty-six (92.3%) patients underwent operative intervention, including surgical resection in 27 (69.2%) patients. CONCLUSION: FD CT imaging allows for a detailed depiction of cortical cerebrovascular anatomy through the capillary phase, in addition to bony cranial anatomy. This enables the safe planning of complex trajectories, including high-obliquity insular electrodes and transsulcal trajectories through "empty sulci" while also providing concurrent imaging of bony anatomy to allow for preoperative planning of drill depth and anchor placement. PMID- 29175568 TI - Borderline Alberta Stroke Programme Early CT Score Patients with Acute Ischemic Stroke Due to Large Vessel Occlusion May Find Benefit with Endovascular Thrombectomy. AB - OBJECTIVE: Selection of patients with acute ischemic stroke for endovascular thrombectomy (EVT) is complex and time-critical. Benefits of EVT are well established for patients with small core infarcts. The aim of this study was to compare clinical outcomes of EVT in patients with larger established infarcts (Alberta Stroke Programme Early CT Score [ASPECTS] <=6) with patients with smaller infarcts (ASPECTS 7-10). METHODS: The study included 355 patients with acute ischemic stroke due to large vessel occlusion who underwent EVT. ASPECTS was assigned to baseline noncontrast computed tomography, and collateral perfusion scores were assigned to multiphase computed tomography angiography. Baseline stroke severity, collateral grading, and clinical outcome data (complication rate, symptomatic intracranial hemorrhage and 90-day modified Rankin Scale score) were compared between patients with borderline (<=6) and high (7-10) ASPECTS. RESULTS: There were 34 (10%) patients with borderline ASPECTS. There was no difference in rate of good clinical outcome (37% vs. 46%, P = 0.852), symptomatic intracerebral hemorrhage (9% vs. 9%, P = 0.984), or mortality (20% vs. 22%, P = 0.818) between patients with borderline ASPECTS and high ASPECTS at 90 days. Moreover, there was no significant difference in collateral perfusion grade. CONCLUSIONS: This study identifies similar clinical benefit of EVT in patients with acute large vessel occlusion stroke with borderline ASPECTS and high ASPECTS. PMID- 29175569 TI - A Randomized Controlled Trial of Low-Dose Tranexamic Acid versus Placebo to Reduce Red Blood Cell Transfusion During Complex Multilevel Spine Fusion Surgery. AB - BACKGROUND: Multilevel spine fusion surgery for adult deformity correction is associated with significant blood loss and coagulopathy. Tranexamic acid reduces blood loss in high-risk surgery, but the efficacy of a low-dose regimen is unknown. METHODS: Sixty-one patients undergoing multilevel complex spinal fusion with and without osteotomies were randomly assigned to receive low-dose tranexamic acid (10 mg/kg loading dose, then 1 mg.kg-1.hr-1 throughout surgery) or placebo. The primary outcome was the total volume of red blood cells transfused intraoperatively. RESULTS: Thirty-one patients received tranexamic acid, and 30 patients received placebo. Patient demographics, risk of major transfusion, preoperative hemoglobin, and surgical risk of the 2 groups were similar. There was a significant decrease in total volume of red blood cells transfused (placebo group median 1460 mL vs. tranexamic acid group 1140 mL; median difference 463 mL, 95% confidence interval 15 to 914 mL, P = 0.034), with a decrease in cell saver transfusion (placebo group median 490 mL vs. tranexamic acid group 256 mL; median difference 166 mL, 95% confidence interval 0 to 368 mL, P = 0.042). The decrease in packed red blood cell transfusion did not reach statistical significance (placebo group median 1050 mL vs. tranexamic acid group 600 mL; median difference 300 mL, 95% confidence interval 0 to 600 mL, P = 0.097). CONCLUSIONS: Our results support the use of low-dose tranexamic acid during complex multilevel spine fusion surgery to decrease total red blood cell transfusion. PMID- 29175570 TI - Reliability of Tokuhashi Score to Predict Prognosis: Comparison of 117 Patients. AB - BACKGROUND: Spinal metastatic disease compromises the quality of life and prognosis of the patients. Prognosis is an important factor for the decision making process and needs to be precise in order to adjust the intensity of therapy. The Tokuhashi score is a universal instrument to determine the prognosis. The objective was to analyze the effectiveness of the Tokuhashi score in determining the prognosis of the patients with spine metastasis by comparing the expected survival time from the Tokuhashi score with the survival time observed among surgical patients. METHODS: This retrospective study was performed from October 2008 to October 2015. The inclusion criteria were symptomatic patients with spinal metastasis who underwent spinal cord decompression and had a minimum of 1-year follow-up. The exclusion criteria were patients without histologic confirmation and were lost to follow-up. The Tokuhashi score was applied, and once the expected survival was defined, it was compared with the survival time observed in the follow-up. RESULTS: The sample studied was 117 patients. The commonly female (58%) and breast spinal metastasis was often observed (25.6%). The patients were followed for a minimum period of 12 months. The actual survival was beyond that estimated by the Tokuhashi score (P < 0.05). CONCLUSION: The Tokuhashi score was not reliable to predict the prognosis. Patients with lower scores that surgical treatment was not recommended by the Tokuhashi score had better quality of life and longer survival after surgery. Tokuhashi score is not a precise tool to establish the best therapy and survival in patients with spinal metastasis. PMID- 29175571 TI - Hypoglossal Schwannoma of Neck: Case Report and Review of Literature. AB - BACKGROUND: Schwannomas are benign, slow-growing neoplasms of the myelin producing Schwann cells of peripheral nervous system that most commonly affect sensory nerves. Hypoglossal schwannomas, tumors of purely motor nerves, comprise <5% of all head and neck schwannomas. Since the first description of a hypoglossal schwannoma in 1933, there have been few case reports of extracranial origins. The most common location of an extracranial hypoglossal schwannoma is in the parapharyngeal space and can mimic paragangliomas. We describe the case of a woman presenting with an enlarging neck mass originally thought to be a paraganglioma but ultimately discovered to be a hypoglossal schwannoma at surgery. CASE DESCRIPTION: A 63-year-old woman had a well-circumscribed, mobile, nontender, 3-cm firm mass at the mandibular angle. On computed tomography, the mass was at the level of the carotid bifurcation, splaying the branching vessels. It was further evaluated with magnetic resonance imaging, which revealed a homogeneous, T2-hyperintense, T1-isointense mass with homogeneous contrast enhancement and scant flow voids. Biopsy revealed a spindle cell mass with positive S-100 staining. She underwent resection with the mass originating from the hypoglossal nerve. CONCLUSIONS: Hypoglossal schwannomas are rare lesions with a variable location along the course of the nerve. An extracranial lesion was described here, which was initially mistaken for a paraganglioma. Surgical resection is the consensus recommendation and is often well tolerated with low risk of long-term recurrence.

AB - BACKGROUND: Microvascular decompression (MVD) and Gamma Knife surgery (GKS) are the primary treatments for trigeminal neuralgia (TN). However, many patients require further surgical treatment after initial surgery for recurrent TN. The aim of this study was to evaluate efficacy and safety of GKS for recurrent TN cases with prior MVD. METHODS: From October 2008 to June 2015, 658 patients at West China Hospital underwent GKS as the only surgical treatment, and 42 patients underwent GKS with prior MVD. The single 4-mm isocenter was located at the cisternal portion of the trigeminal nerve in all patients. Median maximum prescription dose was 85 Gy (range, 70-90 Gy). RESULTS: Median follow-up time was 6.2 years (range, 1.1-10 years). The percentage of patients with or without previous MVD within 1 year was 56.81%, and the percentage of patients who were pain-free was 74.74%. The recurrence rates within 10 years were 49.11% and 43.74% for patients with and without MVD, respectively. Also, 9.52% and 11.04% of patients with and without previous MVD experienced complications as a result of GKS during the long-term follow-up period. Patients who underwent previous MVD showed a significantly lower pain-free rate compared with patients without previous MVD (P = 0.01). There was no statistical significance in the recurrence rate (P = 0.82) or the complications (P = 0.93) in the 2 groups during the long term follow-up period. CONCLUSIONS: For patients with recurrent TN who previously underwent MVD, GKS remains an efficacious and safe mode of treatment.

AB - INTRODUCTION: In Chiari I patients, postoperative pain and discomfort frequently slow the transition back to the home setting. OBJECTIVE: We sought to determine the effect of standardized ketamine infusion protocols on hospital length of stay (LOS). METHODS: This retrospective cohort study reviewed 100 consecutive adult patients undergoing Chiari I decompression. Fifty-nine patients were placed on a 2-3 mg/hr ketamine drip until postoperative day 1. This group was compared with a group who received 2-3 mg/hr of ketamine until postoperative day 2 (19 patients) and patients who did not receive ketamine at all (22 patients). Clinical characteristics, opioid use, LOS, and relative hospitalization costs were assessed. All narcotic amounts were converted into milligram equivalents of morphine. RESULTS: LOS of the short-ketamine group was 46.5 hours when compared with the long-ketamine group (66.8 hours) and no-ketamine group (56.9 hours). There was a statistically significant difference when comparing the short ketamine group with the long-ketamine group and no-ketamine group together (P < 0.001), as well as when compared individually (P = 0.001 and 0.004). The mean cost of hospitalization was 20% less when a short-ketamine protocol was used (P < 0.001). Mean morphine milligram equivalents used postoperatively were 148 mg in the short-ketamine group, 196 mg in the long-ketamine group, and 187 mg in the no ketamine group (P = 0.65). No adverse events from ketamine were noted. CONCLUSIONS: Ketamine at subanesthetic levels may be an effective tool to facilitate early return home postoperatively and may significantly reduce medical costs. PMID- 29175574 TI - Surgical Management and Long-Term Seizure Outcome After Surgery for Temporal Lobe Epilepsy Associated with Cerebral Cavernous Malformations. AB - OBJECTIVE: Operative strategies for cerebral cavernous malformation (CCM) associated temporal lobe epilepsy and timing of surgical intervention continue to be debated. This study aimed to establish an algorithm to evaluate the efficacy of surgical intervention strategies, to maximize positive surgical outcomes and minimize postsurgical neurologic deficits. METHODS: 47 patients having undergone operation for CCM-associated temporal lobe epilepsy were retrospectively reviewed. They had received a diagnostic series for seizure localization, including long-term video electroencephalography (vEEG), high-resolution magnetic resonance imaging (MRI), and positron emission tomography-computed tomography (PET-CT). In patients with mesial temporal lobe CCMs, the involved structures (amygdala, hippocampus, or parahippocampal gyrus) were resected in addition to the lesions. Patients with neocortical epileptogenic CCM underwent extended lesionectomy guided by intraoperative electrocorticography; further performance of amygdalohippocampectomy depended on the extent of hippocampal epileptogenicity. RESULTS: The study cohort contained 28 patients with drug resistant epilepsy (DRE), 12 with chronic epilepsy (CE), and 7 with sporadic seizure (SS). Normal temporal lobe metabolism was seen in 7/7 patients of the SS group. Hypometabolism was found in all patients with chronic disease except for those with posterior inferior and middle temporal gyrus cavernous malformations (CMs). Of the 31 patients with superficial neocortical CCM, 7 had normal PET without hippocampal sclerosis, 14 had ipsilateral temporal lobe hypometabolism without hippocampal sclerosis, and 10 had obvious hippocampal sclerosis and hypometabolism. Seizure freedom in DRE, CE, and SS was 82.1%, 75%, and 100%, respectively. A significant difference was found between lesion laterality and postoperative seizure control; the rate was lower in left-sided cases because of less aggressive resection. CONCLUSIONS: Our study demonstrates that the data from the presurgical evaluation, particularly regarding CM location, responsiveness to antiepileptic drugs, and temporal lobe metabolism, are crucial parameters for choosing surgical approaches to CCM-associated temporal lobe epilepsy. By this operative strategy, patients may receive maximized seizure control and minimized postsurgical neurologic sequelae. PMID- 29175575 TI - Brain Granuloma: Rare Complication of a Retained Catheter. AB - BACKGROUND: Ventriculoperitoneal (VP) shunt is the most frequent treatment for hydrocephalus. VP shunt malfunction is a very common problem in neurosurgical practice, often requiring shunt revision procedures. In some cases, complete removal of a VP shunt may present difficulties, leading the surgeon to leave the ventricular catheter in situ. This decision is often made to avoid possible adverse events, primarily risk of life-threatening hemorrhage. However, a nonfunctioning catheter left in the ventricular system may lead to further complications. CASE DESCRIPTION: We report the case of an adult man who presented with a tumor-like cystic lesion, with mural and nodular postcontrast enhancement, caused by a huge granuloma formed around the tip of a retained ventricular catheter. CONCLUSIONS: This occurrence is extremely rare, and this is the first reported case in the literature. Preoperative differential diagnosis was challenging and included infection, metastasis, dysembryogenetic lesions, and rare reversible porencephalic cysts. According to several physiopathogenetic theories recently reported in the literature, the granuloma may develop as the result of persistent chronic inflammatory reactions between the ventricular catheter left in situ and the brain parenchyma. Application of neuroendoscopic techniques is improving management of VP shunt revisions, allowing safe removal of catheters stuck or lost in the ventricular system. Neuroendoscopy may represent an additional option to avoid possible complications related to retained ventricular catheters. PMID- 29175576 TI - Potential role of the mitochondria as a target for the hepatotoxic effects of (-) epigallocatechin-3-gallate in mice. AB - Green tea and (-)-epigallocatechin-3-gallate (EGCG) have been studied for their obesity-related health effects. Many green tea extract (GTE)-based dietary supplements are commercially-available. Although green tea beverage has a long history of safe use, a growing number of case-reports have linked GTE-based supplements to incidents of hepatotoxicity. Animal studies support the hepatotoxic potential of GTE and EGCG, but the mechanisms remain unclear. Here, we examined the hepatotoxic effects of EGCG in C57BL/6J mice and evaluated changes in hepatic antioxidant response and mitochondria structure and function. Intragastric dosing with EGCG (500 - 750 mg/kg) once daily for 3 d caused hepatic inflammation, necrosis, and hemorrhage. Hepatotoxicity was associated with increased oxidative stress and decreased superoxide dismutase and glutathione peroxidase levels. Real-time PCR and transmission electron microscopy showed decreased hepatic mitochondria copy number in EGCG-treated mice. The mRNA levels of marker genes of respiratory complex I and III, sirtuin 3, forkhead box O3a, and peroxisome-EGCG-treated mice. Sirtuin 3 protein levels were also decreased by EGCG. Our data indicate the mitochondria may be a target for EGCG, and that inhibition of mitochondria function/antioxidant response may be important for the hepatotoxicity of bolus EGCG. PMID- 29175577 TI - Aflatoxin exposure in Nigerian children with severe acute malnutrition. AB - Aflatoxin exposure is an important public health concern in sub-Saharan Africa as well as parts of Latin America and Asia. In addition to hepatocellular carcinoma, chronic aflatoxin exposure is believed to play a role in childhood growth impairment. The most reliable biomarker of chronic aflatoxin exposure is the aflatoxin-albumin adduct, as measured by ELISA or isotope dilution mass spectrometry (IDMS). In this report, we have used high resolution LC-MS/MS with IDMS to quantitate AFB1-lysine in an extremely vulnerable population of Nigerian children suffering from severe acute malnutrition. To increase the sensitivity and reliability of the analyses, a labelled AFB1-13C615N2-lysine internal standard was synthesized. AFB1-lysine concentrations in this population ranged between 0.2 and 59.2 pg/mg albumin, with a median value of 2.6 pg/mg albumin. AFB1-lysine concentrations were significantly higher in stunted children (median = 4.6 pg/mg) compared to non-stunted (1.2 pg/mg), as well as in children with severe acute malnutrition (4.3 pg/mg) compared to controls (0.8 pg/mg). The median concentrations were also higher in children with kwashiorkor (6.3 pg/mg) compared to those suffering from marasmus (0.9 pg/mg). This is the first report of the use of high-resolution mass spectrometry to quantitate AFB1-lysine in humans. PMID- 29175581 TI - Application of SHAPE reveals in vivo RNA folding under normal and growth-stressed conditions in the human parasite Entamoeba histolytica. AB - Selective 2'-hydroxyl acylation analyzed by primer extension (SHAPE) is a versatile sequence independent method to probe RNA structure in vivo and in vitro. It has so far been tried mainly with model organisms. We show that cells of Entamoeba histolytica, a protozoan parasite of humans are hyper-sensitive to the in vivo SHAPE reagent, NAI, and show rapid loss of viability and RNA integrity. We optimized treatment conditions with 5.8S rRNA and Eh_U3 snoRNA to obtain NAI-modification while retaining RNA integrity. The modification patterns were highly reproducible. The in vivo folding was different from in vitro and correlated well with known interactions of 5.8S rRNA with proteins in vivo. The Eh_U3 snoRNA also showed many differences in its in vivo versus in vitro folding, which correlated with conserved interactions of this RNA with 18S rRNA and 5' ETS. Further, Eh_U3 snoRNA obtained from serum-starved cells showed an open 3' hinge structure, indicating disruption of 5'-ETS interaction. This could contribute to the observed slow processing of pre-rRNA in starved cells. Our work shows the applicability of SHAPE to study in vivo RNA folding in a parasite and will encourage the use of this reagent for RNA structure analysis in other such organisms.

AB - Permethrin is a pyrethroid pesticide that was previously reported to promote fat accumulation and insulin resistance in vitro. A recent study in female mice also found that permethrin could promote high fat-induced insulin resistance. The effects of permethrin on glucose and lipid metabolisms in male mice, however, remain unknown. The purpose of this study was to investigate the effects and interactions of permethrin exposure (50, 500, and 5000 MUg/kg body weight/day) and dietary fat (low fat, 4% w/w; high fat, 20% w/w) on development of obesity and insulin resistance in male C57BL/6J mice. Our results showed that permethrin treatment significantly increased body weight, fat mass, and insulin resistance with high fat diet, but not with low fat diet, without influencing energy intake. Permethrin treatment also significantly increased serum levels of insulin, glucose, leptin, triglycerides and cholesterol. Further results showed that permethrin inhibited AMP-activated protein kinase in white adipose tissue. These results suggest that permethrin interacts with dietary fat to alter lipid and glucose metabolisms in male C57BL/6J mice.

PMID- 29175582 TI - Usefulness of coronary postmortem computed tomography angiography to detect lesions in the coronary artery and myocardium in cases of sudden death. AB - Coronary postmortem computed tomography angiography (coronary PMCTA) has been introduced as a routine examination procedure for autopsy at our department. Here, we reviewed eight autopsy cases in which apparent histopathological changes including acute myocardial infarction (AMI), anomalous aortic origin of a coronary artery (AAOCA), hypertrophic obstructive cardiomyopathy (HOCM) and acute myocarditis were involved in the cause of death. For investigation of the coronary artery and shape of the heart, coronary PMCTA was valuable in detecting narrowing or obstruction of coronary artery in AMI, indicating an anomalous aortic origin of the left coronary artery in AAOCA, and demonstrating septal hypertrophy and intracavitary obstruction in HOCM. However, it was debatable whether the hypervascularity demonstrated by coronary PMCTA in the case of acute myocarditis was more prominent than the vascular images obtained in other cases without inflammation. Thus, coronary PMCTA appeared to be useful not only for detection of coronary artery stenosis, but also for indicating other distinctive changes involved in AAOCA and HOCM. PMID- 29175583 TI - Assessing the FBI's Native American STR database for random match probability calculations. AB - In forensic statistics, the random match probability (RMP) is the probability that a "match" would occur by coincidence while the likelihood ratio (LR) describes the strength of DNA evidence. Using these statistics to assess the weight of DNA evidence requires an appropriate and well-characterized population specific short tandem repeat (STR) database to reliably estimate allele frequencies. This study compared several Native American-specific STR datasets, including those not represented in the CODIS Native American database, and revealed that increasing the number of STR markers resulted in lower RMP values while a theta adjustment from 0.03 to 0.04 generated increases in RMP. To prevent biases that may arise from the underrepresentation of tribes in the current CODIS Native American database, data derived from tribes in different geographic regions and language families are necessary to ensure inclusive representation of the Native American population and generate more reliable statistical results.

PMID- 29175585 TI - Unprotected primary sulfonamide group facilitates ring-forming cascade en route to polycyclic [1,4]oxazepine-based carbonic anhydrase inhibitors. AB - 4-Chloro-3-nitrobenzenesulfonamide reacted cleanly at room-temperature with a range of bis-electrophilic phenols bearing an NH-acidic functionality (secondary carboxamide or pyrazole) in the ortho-position. This produced a novel class of [1,4]oxazepine-based primary sulfonamides which exhibited strong inhibition of therapeutically relevant human carbonic anhydrases. 2-Chloronitrobenzene did not enter a similar cyclocondensation process, even under prolonged heating. Thus, the primary sulfonamide functionality plays a dual role by enabling the [1,4]oxazepine ring construction and acting as a enzyme prosthetic zinc-binding group when the resulting [1,4]oxazepine sulfonamides are employed as carbonic anhydrase inhibitors. PMID- 29175586 TI - Design, synthesis of novel Triazolones and bis-Triazolones derivatives under ultrasound irradiation and evaluation as potent angiotensin converting enzyme (ACE) inhibitors. AB - The condensation of several primary amines and diamines with various N1 ethoxycarbonyles N1-tosylhydrazonates (1a-b), triazolones (2) and bis-triazolone (3) resulted in ethanol under ultrasound irradiation. Compared with the conventional methods, the main advantages of the present procedure are milder conditions, shorter reaction time and higher yields. The newly synthesized compounds were evaluated for angiotensin I-converting enzyme (ACE) inhibition. The results were compared to Captopril as a reference drug. Compounds 3b, 2h, 3a, 2d, and 2f showed not only inhibition activity with IC50 values of 0.162, 0.253, 0.253, 0.281 and 0.382 uM, respectively, but also minimal toxicity. The docking of chemical compounds in the ACE active site showed possible inhibitory effect of all compounds on the catalytic activity of the enzyme, which would satisfactorily explain the anti-hypertensive effect of these compounds. PMID- 29175587 TI - Design, synthesis and molecular modeling studies of new series of antitumor 1,2,4 triazines with potential c-Met kinase inhibitory activity. AB - The receptor tyrosine kinase c-Met is an attractive target for therapeutic treatment of cancers nowadays. Herein we describe the design and synthesis of a novel series of 1,2,4-triazine derivatives based on our lead NCI 748494/1, possessing different N-linkers to aromatic and heterocyclic rings. In addition, a molecular hybrid series combining the 1,2,4-triazine scaffold to the well-known anticancer drug 6-mercaptopurine (6-MP) was synthesized in order to explore its "double-drug" antitumor effect. The synthesized compounds were evaluated for their in vitro antitumor activity against three c-Met addicted cancer cell lines (A549, HT-29 and MKN-45). Most compounds showed moderate to excellent antitumor activity. Compound 3d showed potent inhibitory activity more than reference Foretinib, BMS-777607 and NCI 748494/1 with IC50 values in the range 0.01-0.31 uM against the cancer cell lines. The calculated IC50 of 3d against c-Met kinase was found to be 2.71 uM, which is more potent than NCI 748494/1 (IC50 = 31.70 uM). Docking studies were performed to identify the binding mode of 3d with c-Met kinase domain in comparison to moderate and weak derivatives. The present study clearly demonstrates that 1,2,4-triazine ring exhibits promising antitumor activity and the double-drug optimization strategy led to identifying 3d as a potent c-Met kinase inhibitor suitable for further development. PMID- 29175588 TI - Modification of Bischler-Mohlau indole derivatives through palladium catalyzed Suzuki reaction as effective cholinesterase inhibitors, their kinetic and molecular docking studies. AB - Due to the immense importance of aryl indole nucleus, herein we report the palladium-catalyzed arylation of N-substituted 2-aryl indole utilizing Suzuki Miyaura cross coupling methodology. The biological screening for cholinesterase inhibition of the resulted biaryl indole moieties was carried out to evaluate their pharmacological potential, expecting to involve the development of new therapeutics for various inflammatory, cardiovascular, gastrointestinal and neurological diseases. This research work also involved the use of utilization of microwave-assisted organic synthesis (MAOS) for the synthesis of Bischler-Mohlau indole which is further biarylated via palladium-catalyzed cross coupling reaction. All the synthetic compounds (3a-n) were tested for cholinesterase inhibition and exhibited high level of AChE inhibitory activities. Interestingly, compounds 3m and 3n were found to be dual inhibitors, however, remaining compound exhibited no inhibitory activity against BChE. The biological potential of the resulted compounds was explained on the basis of molecular docking studies, performed against AChE and BChE, exploring the probable binding modes of most potent inhibitors. PMID- 29175589 TI - Design, synthesis, monoamine oxidase inhibition and docking studies of new dithiocarbamate derivatives bearing benzylamine moiety. AB - A new series of thirteen 2-[(4-fluorophenyl)(4-nitrobenzyl)amino]-2-oxoethyl-1 substituted-carbodithioate derivatives (4a-4m) were synthesized and tested for their human monoamine oxidase A and B (hMAO-A and hMAO-B) inhibitory potential by an in vitro fluorometric method. Most of the compounds have found to be selective towards MAO-B than MAO-A. Compound 4j that carrying 4-nitrophenyl piperazine moiety, was detected as the most active agent amongst all compounds with the IC50 value of 0.097 +/- 0.003 uM for MAO-B while that of selegiline was 0.040 +/- 0.002 uM. The enzyme kinetic study reported that compound 4j is a reversible and non-competitive inhibitor. Interaction modes between the hMAO-B and compound 4j were determined by docking studies. The study also revealed that compound 4j has the highest binding scores. Besides, compound 4j has not cytotoxicity at its effective concentration against hMAO-B. PMID- 29175590 TI - Recovering Wood and McCarthy's ERP-prototypes by means of ERP-specific procrustes rotation. AB - BACKGROUND: The misallocation of treatment-variance on the wrong component has been discussed in the context of temporal principal component analysis of event related potentials. There is, until now, no rotation-method that can perfectly recover Wood and McCarthy's prototypes without making use of additional information on treatment-effects. NEW METHOD: In order to close this gap, two new methods: for component rotation were proposed. After Varimax-prerotation, the first method identifies very small slopes of successive loadings. The corresponding loadings are set to zero in a target-matrix for event-related orthogonal partial Procrustes- (EPP-) rotation. The second method generates Gaussian normal distributions around the peaks of the Varimax-loadings and performs orthogonal Procrustes-rotation towards these Gaussian distributions. Oblique versions of this Gaussian event-related Procrustes- (GEP) rotation and of EPP-rotation are based on Promax-rotation. RESULTS: A simulation study revealed that the new orthogonal rotations recover Wood and McCarthy's prototypes and eliminate misallocation of treatment-variance. In an additional simulation study with a more pronounced overlap of the prototypes GEP Promax-rotation reduced the variance misallocation slightly more than EPP Promax-rotation. Comparison with Existing Method(s): Varimax- and conventional Promax-rotations resulted in substantial misallocations of variance in simulation studies when components had temporal overlap. A substantially reduced misallocation of variance occurred with the EPP-, EPP Promax-, GEP-, and GEP Promax-rotations. CONCLUSIONS: Misallocation of variance can be minimized by means of the new rotation methods: Making use of information on the temporal order of the loadings may allow for improvements of the rotation of temporal PCA components. PMID- 29175591 TI - Linking T cell epitopes to a common linear B cell epitope: A targeting and adjuvant strategy to improve T cell responses. AB - Immune complexes are potent mediators of cellular immunity and have been extensively studied for their disease mediating properties in humans and for their role in anti-cancer immunity. However, a viable approach to use antibody complexed antigen as vehicle for specific immunotherapy has not yet reached clinical use. Since virtually all people have endogenous antibodies against tetanus toxoid (TTd), such commonly occurring antibodies are promising candidates to utilize for immune modulation. As an initial proof-of-concept we investigated if anti-tetanus IgG could induce potent cross-presentation of a conjugate with SIINFEKL, a MHC class I presented epitope of ovalbumin (OVA), to TTd. This protein conjugate enhanced OVA-specific CD8+ T cell responses when administrated to seropositive mice. Since TTd is poorly defined, we next investigated whether a synthetic peptide-peptide conjugate, with a chemically defined linear B cell epitope of tetanus toxin (TTx) origin, could improve cellular immune responses. Herein we identify one linear B cell epitope, here after named MTTE thru a screening of overlapping peptides from the alpha and beta region of TTx, and by assessment of the binding of pooled IgG, or individual human IgG from high-titer TTd vaccinated donors, to these peptides. Subsequently, we developed a chemical protocol to synthesize defined conjugates containing multiple copies of MTTE covalently attached to one or more T cell epitopes of choice. To demonstrate the potential of the above approach we showed that immune complexes of anti-MTTE antibodies with MTTE-containing conjugates are able to induce DC and T cell activation using model antigens.

AB - Cell-derived extracellular vesicles (EVs) are involved in the pathogenesis of rheumatoid arthritis (RA), playing important roles in antigen presentation, inflammation, angiogenesis, cell-cell signal communication, thrombosis, and articular cartilage extracellular matrix degradation. Understanding the pathogenic mechanism of RA is important for developing therapies. The pathogenic indicators of RA, such as submicron-sized EVs, represent promising biomarkers for evaluating RA activity. This review summarizes the recent advances in understanding the pathogenesis of RA, and sheds light on the pathogenic as well as anti-inflammatory or immunosuppressive roles of EVs. We suggest that EVs could be harnessed as tools for drug delivery or targets for RA therapies. PMID- 29175593 TI - Rational selection of immunodominant and preserved epitope Sm043300e from Schistosoma mansoni and design of a chimeric molecule for biotechnological purposes. AB - Human schistosomiasis is a neglected tropical disease of great importance in public health. A large number of people are infected with schistosomiasis, making vaccine development and effective diagnosis important control strategies. A rational epitope prediction workflow using Schistosoma mansoni hypothetical proteins was previously presented by our group, and an improvement to that approach is presented here. Briefly, immunodominant epitopes from parasite membrane proteins were predicted by reverse vaccinology strategy with additional in silico analysis. Furthermore, epitope recognition was evaluated using sera of individuals infected with S. mansoni. The epitope that stood out in both in silico and in vitro assays was used to compose a rational chimeric molecule to improve immune response activation. Out of 2185 transmembrane proteins, four epitopes with high binding affinities for human and mouse MHCII molecules were selected through computational screening. These epitopes were synthesized to evaluate their ability to induce TCD4+ lymphocyte proliferation in mice. Sm204830e and Sm043300e induced significant TCD4+ proliferation. Both epitopes were submitted to enzyme-linked immunosorbent assay to evaluate their recognition by IgG antibodies from the sera of infected individuals, and epitope Sm043300 was significantly recognized in most sera samples. Epitope Sm043300 also showed good affinity for human MHCII molecules in molecular docking, and its sequence is curiously highly conserved in four S. mansoni proteins, all of which are described as G-protein-coupled receptors. In addition, we have demonstrated the feasibility of incorporating this epitope, which showed low similarity to human sequences, into a chimeric molecule. The stability of the molecule was evaluated by molecular modeling aimed at future molecule production for use in diagnosis and vaccination trials. PMID- 29175594 TI - Reduced PTEN involved in primary immune thrombocytopenia via contributing to B cell hyper-responsiveness. AB - Phosphatase and tensin homolog (PTEN) is thought to mediate B cell activation by negatively regulating the phosphoinositide 3-kinase (PI3K) signaling pathway. This pathway is important for activation, growth, and proliferation. Although enhanced B cell receptor (BCR) signaling contributes to increased B cell activity in immune thrombocytopenia (ITP), the role of PTEN is unclear. In this study, we analyzed B cells of ITP patients using flow cytometry and found that all B cell subsets, excluding memory B cells, showed lower PTEN expression than cells from healthy controls (HCs). PTEN expression was also positively-correlated with blood platelet count, although levels were lower in patients who were platelet autoantibody-positive compared with those who were negative. We next evaluated the effects of IL-21, anti-IgM, and CD40L on PTEN expression, demonstrating that they were potent inducers of PTEN expression in normal B cells. Induction of PTEN expression was lower in B cells of ITP patients. We also found that IL-21 increased the proportion of plasma cells in peripheral blood mononuclear cells (PBMCs) of ITP patients, independent of BCR signaling. This effect was reproducible using PTEN inhibitors with cells from HCs. In summary, defective PTEN expression, regulation, and function all contribute to the B cell hyper responsiveness that associates with ITP.

AB - OBJECTIVES: To survey potential stakeholders to obtain information relevant to the production of a video on teaching acupressure for sports injury management, and gain feedback from potential users on the prototype video. DESIGN: Focus groups and online survey methods nested within a knowledge translation framework. PARTICIPANTS: Four focus groups (n = 24) were conducted, two with sports medics and two with sports physiotherapists as a part of the development of a prototype video. Nineteen stakeholders viewed the prototype video and participated in the subsequent online survey. MAIN OUTCOME MEASURES: Focus groups' transcripts were analysed to develop themes using a general inductive approach. Survey data analysis incorporated quantitative and qualitative analysis. RESULTS: Three key themes concerning the design of the video emerged from the focus groups: 1) the recommendation for both demonstration and verbal instructions on the acupressure technique; 2) keeping the content of the video to a minimum; and 3) the need for professionalism in the production of the video, and highlighting the presenter's expertise and qualifications. The survey participants found the video to be clear and professional. CONCLUSIONS: Collectively these studies described the development and assessment of a user-oriented instructional video on teaching of acupressure for the management of sports injuries.

AB - Silver nanoparticles (AgNPs) are used in the medical, pharmaceutical and food industry. Adverse effects and toxicity induced by AgNPs upon cardiac function related to nitric oxide (NO) and oxidative stress (OS) are described. AgNPs toxicity may be influenced by cardiovascular pathologies such as hypertension. However, the molecules involved under pathophysiological conditions are not well studied. The aim of this work was to evaluate perfusion pressure (PP) and left ventricle pressure (LVP) as physiological parameters of cardiovascular function in response to AgNPs, using isolated perfused hearts from spontaneously hypertensive rats (SHR), and identify the role of NO and OS. The results suggest that AgNPs reduced NO derived from endothelial/inducible NO-synthase and increased OS, leading to increased and sustained vasoconstriction and myocardial contractility. Additionally, the hypertension condition alters phenylephrine (Phe) and acetylcholine (ACh) classic effects. These data suggest that hypertension intensified AgNPs-cardiotoxicity. Nevertheless, the precise mechanism of action is still under elucidation. PMID- 29175597 TI - Delivery of NF-kappaB shRNA using carbamate-mannose modified PEI for eliminating cancer stem cells. AB - The presence of cancer stem cells (CSCs) is one of the main reasons that cause cancer relapse and metastasis. In this study, NF-kappaB shRNA was delivered to target CSCs using carbamate-mannose modified PEI (CMP) as a non-viral gene vector. The polymer was synthesized by blocking primary amine groups of branched PEI (10kDa) through nucleophilic addition between PEI and protected mannose functionalized cyclic carbonate, followed by mannose deprotection. CMP/control shRNA nanocomplexes showed lower cytotoxicity and higher transfection efficiency in 4T1 murine breast cancer cells than unmodified PEI/control shRNA nanocomplexes. Importantly, CMP/NF-kappaB shRNA nanocomplexes (CMPN) were capable of inhibiting migration and invasion, decreasing mammosphere and colony formation and lowering ALDH+ CSC population. Furthermore, CMPN not only induced apoptosis and inhibited cell proliferation, but also sensitized the cells to the treatment with doxorubicin-loaded micellar nanoparticles. Therefore, CMPN may provide a promising approach for eliminating CSCs to prevent cancer relapse and metastasis. PMID- 29175598 TI - Low immunogenic bio-nanocapsule based on hepatitis B virus escape mutants. AB - Bio-nanocapsules (BNCs) consisting of hepatitis B virus surface antigen (HBsAg) L proteins and phospholipids are used as efficient non-viral carriers for liver specific delivery of genes and drugs. Considering the administration to HB vaccinees and HB patients, endogenous anti-HBsAg immunoglobulins (HBIGs) may reduce the delivery efficacy and prevent repetitive administration. Therefore, low immunogenic BNCs were generated by inserting two point mutations in the HBsAg L protein, which were found in HBV escape mutants. Escape mutant-type BNC (emBNC) showed 50% lower HBIG binding capacity than that of parental BNC (wtBNC). It induced HBIG production to a lesser extent than that associated with wtBNC in BALB/c mice. The emBNC could accumulate into human hepatocyte-derived tumor in mice pre-treated with HBIGs. The complex of emBNC and cationic liposomes could deliver plasmid DNA to HepG2 cells efficiently in the presence of HBIGs. Thus, emBNC could evade HBIG-neutralizing antibodies, expanding the clinical utility of BNC-based nanomedicine.

The B-lymphoma neoplastic cells express on their surfaces a clone-specific immunoglobulin receptor (Ig BCR). The peptide A20-36 (pA20-36) selectively binds to the Ig-BCR of A20 lymphoma cells. In this work, we demonstrated the ability of core-shell chitosan HA-NPs decorated with pA20-36 to specifically target A20 cells and reduce the tumor burden in a murine xenograft model. We monitored tumor growth using high frequency ultrasonography and demonstrated targeting specificity and kinetics of the NPs via in vivo fluorescent reflectance imaging. This result was also confirmed by ex vivo magnetic resonance imaging and confocal microscopy. In conclusion, we demonstrated the ability of NPs loaded with fluorescent and paramagnetic tracers to act as multimodal imaging contrast agents and hence as a non-toxic, highly specific theranostic system.

AB - Analysis of human DNA methylation (DNAm) can provide additional investigative leads in crime cases, e.g. the type of tissue or body fluid, the chronological age of an individual, and differentiation between identical twins. In contrast to the genetic profile, the DNAm level is not the same in every cell. At the single cell level, DNAm represents a binary event at a defined CpG site (methylated versus non-methylated). The DNAm level from a DNA extract however represents the average level of methylation of the CpG of interest of all molecules in the forensic sample. The variance of DNAm levels between replicates is often attributed to technological issues, i.e. degradation of DNA due to bisulfite treatment, preferential amplification of DNA, and amplification failure. On the other hand, we show that stochastic variations can lead to gross fluctuation in the analysis of methylation levels in samples with low DNA levels. This stochasticity in DNAm results is relevant since low DNA amounts (1pg - 1ng) is rather the norm than the exception when analyzing forensic DNA samples. This study describes a conceptual analysis of DNAm profiling and its dependence on the amount of input DNA. We took a close look at the variation of DNAm analysis due to DNA input and its consequences for different DNAm-based forensic applications. As can be expected, the 95%-confidence interval of measured DNAm becomes narrower with increasing amounts of DNA. We compared this aspect for two different DNAm based forensic applications: body fluid identification and chronological age determination. Our study shows that DNA amount should be well considered when using DNAm for forensic applications. PMID- 29175601 TI - Sciatica due to hydroxyapatite deposition disease.

AB - A series of quinoline based peptides were synthesized by a one-pot reaction through Ugi-four component condensation of lipoic acid, cyclohexyl isocyanide, aniline derivatives and 2-methoxy quinoline-3-carbaldehyde derivatives under microwave irradiation. The products were obtained in excellent yields and high purity. Solvent optimization and the effect of microwave irradiation with various powers were also observed. All the synthesized compounds were characterized by FTIR, NMR spectral data and elemental analysis. A total of eight peptides were subjected to antimicrobial, antioxidant and toxicity evaluation. Among them, four peptides showed potential towards antibacterial screening with Bacillus cereus, Staphylococcus aureus, Escherichia coli, Enterococcus faecalis and Candida albicans, Candida utilis and three peptides showed antioxidant test positive (DPPH). Besides, toxicity of all the peptides were evaluated by using brine shrimp and it was observed that four peptides showed mortality rate less than 50% up to 48h. Molecular docking studies revealed that the higher binding affinity of the two peptides toward DNA gyrase than ciprofloxacin based on Libdock score. The described chemistry represents a facile tool to synthesize complex heterocycles of pharmaceutical relevance in a highly efficient and one-pot fashion. The advantages of this method are its green approach, inexpensive solvent, shorter reaction times and excellent yields. PMID- 29175603 TI - Monitoring of hydrogen peroxide production under photodynamic treatment using protein sensor HyPer. AB - An interest to H2O2 accumulation under photodynamic treatment can be explained by its participation in intracellular signal cascades. It is important not only to detect H2O2 generation, but also to trace the dynamics of its intracellular content. In the present study the dynamics of cellular H2O2 content under photodynamic treatment was analyzed using genetically encoded reversible H2O2 sensitive sensor HyPer. Real-time detecting of H2O2 production after photodynamic treatment was performed using the protein sensor and individual features of action of different photosensitizers were revealed. Photodynamic treatment with a number of chlorin and phthalocyanine photosensitizers was found to induce secondary production of H2O2 in the cells. Three types of dynamic responses were registered: monotonous increase of H2O2 level during the entire observation time in the presence of Fotoditazin and Holosens; transient short-term accumulation in the presence of Radachlorin and Phthalosens; and relatively low-level stable increase in the presence of Photosens. The listed photosensitizers differ significantly in intracellular localization and physicochemical properties, which can determine the differences in the response of H2O2 after the photodynamic treatment. In general, it has been shown that the rapid transient H2O2 response is typical for hydrophobic compounds localized in membrane cell structures, whereas in the presence of more hydrophilic dyes a prolonged monotonous H2O2 accumulation occurs.

AB - In recent years, the management of food waste processing has emerged as a major concern. One such type of food waste, grape pomace, has been shown to be a great source of bioactive compounds which might be used for more environmentally - friendly processes for the synthesis of nanomaterials. In this study, grape pomace of Vitis vinifera has been used for the obtainment of an aqueous extract. Firstly, the reducing activity, total phenolic content and DPPH scavenging activity of the aqueous extract were determined. Then, the aqueous extract was used for the synthesis of gold and silver nanoparticles. The formation of spherical and stable nanoparticles with mean diameters of 35.3+/-5.2nm for Au@GP and 42.9+/-6.4nm for Ag@GP was confirmed by UV-vis spectroscopy and transmission electron microscopy. Furthermore, the functional group of biomolecules present in grape pomace extract, Au@GP and Ag@GP, were characterized by Fourier transform infrared spectroscopy prior to and after the synthesis, in order to obtain information about the biomolecules involved in the reducing and stabilization process. This study is the first to deal with the use of Vitis vinifera grape pomace in obtaining gold and silver nanoparticles through an eco-friendly, quick, one-pot synthetic route. PMID- 29175605 TI - Elevated CO2 leads to carbon sequestration by modulating C4 photosynthesis pathway enzyme (PPDK) in Suaeda monoica and S. fruticosa. AB - The C4 halophytic species Suaeda monoica and S. fruticosa, possess the C4 photosynthesis pathway without Kranz anatomy were grown at ambient (470ppm CO2) and elevated (850ppm CO2) atmospheric CO2 under control containment facility to study the plant response under CO2 stress condition. The relative growth of both Suaeda species was enhanced with atmospheric CO2 enrichment compared to control (ambient) condition. The photosynthesis rate was found 2.5MUmolCO2m-2s-1 in both species under stress condition compared to about 1.9MUmolCO2m-2s-1 under control conditions. About 0.3molH2Om-2s-1 conductance was detected under an unstressed condition which decreased significantly to ~0.07molH2Om-2s-1 on the 6th day of stress treatment. Similarly, transpiration rate was also decreased significantly from 4.4-5.2mmolH2Om-2s-1 to 1.7-1.9 under stress condition. In contrast, VpdL increased significantly from 1.9kPa to 2.5kPa under stress condition. A higher total chlorophyll content observed in S. monoica (56.36mgg-1 tissue) compared to S. fruticosa (33.12mgg-1 tissue) under unstressed (control) condition. A significant increase was found in the total chlorophyll content of S. fruticosa (45.47mgg-1 tissue) with stress treatment compared to control (33.12mgg-1 tissue). In contrast, the total chlorophyll decreased in S. monoica (51.58mgg-1 tissue) under similar stress condition compared to control plants (56.36mgg-1 tissue). About 6-6.8mg total sugar per gram tissue found under control condition which enhanced further (7.5 to 11mgg-1 tissue) under stress condition. Similarly, total reducing sugar (~2mgg-1 tissue) and total starch content (6.5-11mgg-1 tissue) increased under stress condition. About 6.5- and 3- fold higher expression of PPDK gene was observed for S. monoica and S. fruticosa, respectively under CO2 stress condition. PPDK (1.2- and 1.5- fold) and antioxidant enzymes; APX (12.7- and two-fold), CAT (2.2- and 6.4- fold) and SOD (4.6- and 94- fold) enhanced significantly in S. fruticosa and S. monoica, respectively under high CO2 stress condition compared to control plants. Overall, it was observed that PPDK enzyme plays a key role in C4 photosynthesis pathway and S. monoica is a potential candidate to be explored further for the saline agricultural and CO2 capture. PMID- 29175606 TI - High rates of colonisation by ampicillin-resistant enterococci in residents of long-term care facilities in Porto, Portugal. AB - This study evaluated the occurrence of enterococci resistant to clinically relevant antibiotics in long-term care facility (LTCF) residents in Porto, Portugal, a region with high rates of multidrug-resistant enterococci in infected patients and healthy carriers. Faecal samples from 48 residents in two LTCFs (2015-2016) were enriched (with/without antibiotics) and plated on Slanetz Bartley with/without the same antibiotics (ampicillin/vancomycin/linezolid). Two colonies per morphology/sample were selected for susceptibility testing and species identification. Clonality was established by PFGE and MLST. Genes coding for vancomycin resistance (vanA/vanB), virulence and plasmids (replicases) were searched by PCR. A total of 285 isolates were obtained, comprising Enterococcus faecalis, Enterococcus faecium, Enterococcus raffinosus and Enterococcus avium colonising 83%, 77%, 27% and 10% of residents, respectively. Residents from both LTCFs were colonised with vancomycin-resistant E. faecium (VanA-VREfm) (4 residents; 8%) and/or ampicillin-resistant (AmpR) (24 residents; 50%) E. raffinosus, E. faecium and E. avium. Enterococcus faecium previously associated with major human clonal lineages (ST18/ST78) or animal clones (ST393) were identified. Some PFGE types of E. faecium, E. raffinosus and E. avium were shared by residents of both LTCFs. Recent antibiotic exposure was significantly associated with colonisation by AmpR enterococci. Residents from Portuguese LTCFs were colonised with high rates of AmpR enterococci and similar rates of VREfm compared with other EU countries. A high colonisation rate with widespread enterococcal lineages that could be selected by antibiotic consumption in LTCFs was uncovered. These findings suggest that antimicrobial stewardship is warranted in LTCFs, which constitutes a significant challenge in a home-based setting. PMID- 29175607 TI - Stability of two-species communities: Drift, environmental stochasticity, storage effect and selection. AB - The dynamics of two competing species in a finite size community is one of the most studied problems in population genetics and community ecology. Stochastic fluctuations lead, inevitably, to the extinction of one of the species, but the relevant timescale depends on the underlying dynamics. The persistence time of the community has been calculated both for neutral models, where the only driving force of the system is drift (demographic stochasticity), and for models with strong selection. Following recent analyses that stress the importance of environmental stochasticity in empirical systems, we present here a general theory of the persistence time of a two-species community where drift, environmental variations and time independent selective advantage are all taken into account. PMID- 29175608 TI - Temporal ordering of substitutions in RNA evolution: Uncovering the structural evolution of the Human Accelerated Region 1. AB - The Human Accelerated Region 1 (HAR1) is the most rapidly evolving region in the human genome. It is part of two overlapping long non-coding RNAs, has a length of only 118 nucleotides and features 18 human specific changes compared to an ancestral sequence that is extremely well conserved across non-human primates. The human HAR1 forms a stable secondary structure that is strikingly different from the one in chimpanzee as well as other closely related species, again emphasizing its human-specific evolutionary history. This suggests that positive selection has acted to stabilize human-specific features in the ensemble of HAR1 secondary structures. To investigate the evolutionary history of the human HAR1 structure, we developed a computational model that evaluates the relative likelihood of evolutionary trajectories as a probabilistic version of a Hamiltonian path problem. The model predicts that the most likely last step in turning the ancestral primate HAR1 into the human HAR1 was exactly the substitution that distinguishes the modern human HAR1 sequence from that of Denisovan, an archaic human, providing independent support for our model. The MutationOrder software is available for download and can be applied to other instances of RNA structure evolution.

AB - The ability to rapidly learn from others by instruction is an important characteristic of human cognition. A recent study found that the rapid transfer from initial instructions to fluid behavior is supported by changes of functional connectivity between and within several large-scale brain networks, and particularly by the coupling of the dorsal attention network (DAN) with the cingulo-opercular network (CON). In the present study, we extended this approach to investigate how these brain networks interact when stimulus-response mappings are altered by novel instructions. We hypothesized that residual stimulus response associations from initial practice might negatively impact the ability to implement novel instructions. Using functional imaging and large-scale connectivity analysis, we found that functional coupling between the CON and DAN was generally at a higher level during initial than reversal learning. Examining the learning-related connectivity dynamics between the CON and DAN in more detail by means of multivariate patterns analyses, we identified a specific subset of connections which showed a particularly high increase in connectivity during initial learning compared to reversal learning. This finding suggests that the CON-DAN connections can be separated into two functionally dissociable yet spatially intertwined subsystems supporting different aspects of short-term task automatization. PMID- 29175611 TI - Resting-state functional connectivity remains unaffected by preceding exposure to aversive visual stimuli. AB - While much is known about immediate brain activity changes induced by the confrontation with emotional stimuli, the subsequent temporal unfolding of emotions has yet to be explored. To investigate whether exposure to emotionally aversive pictures affects subsequent resting-state networks differently from exposure to neutral pictures, a resting-state fMRI study implementing a two-group repeated-measures design in healthy young adults (N = 34) was conducted. We focused on investigating (i) patterns of amygdala whole-brain and hippocampus connectivity in both a seed-to-voxel and seed-to-seed approach, (ii) whole-brain resting-state networks with an independent component analysis coupled with dual regression, and (iii) the amygdala's fractional amplitude of low frequency fluctuations, all while EEG recording potential fluctuations in vigilance. In spite of the successful emotion induction, as demonstrated by stimuli rating and a memory-facilitating effect of negative emotionality, none of the resting-state measures was differentially affected by picture valence. In conclusion, resting state networks connectivity as well as the amygdala's low frequency oscillations appear to be unaffected by preceding exposure to widely used emotionally aversive visual stimuli in healthy young adults. PMID- 29175612 TI - Making sense of objects lying around: How contextual objects shape brain activity during action observation. AB - Action recognition involves not only the readout of body movements and involved objects but also the integration of contextual information, e.g. the environment in which an action takes place. Notably, inferring superordinate goals and generating predictions about forthcoming action steps should benefit from screening the actor's immediate environment, in particular objects located in the actor's peripersonal space and thus potentially used in following action steps. Critically, if such contextual objects (COs) afford actions that are semantically related to the observed action, they may trigger or facilitate the inference of goals and the prediction of following actions. This fMRI study investigated the neural mechanisms underlying the integration of COs in semantic and spatial relation to observed actions. Specifically, we tested the hypothesis that the inferior frontal gyrus (IFG) subserves this integration. Participants observed action videos in which COs and observed actions had common overarching goals or not (goal affinity) and varied in their location relative to the actor. High goal affinity increased bilateral activity in action observation network nodes, i.e. the occipitotemporal cortex and the intraparietal sulcus, but also in the precuneus and middle frontal gyri. This finding suggests that the semantic relation between COs and actions is considered during action observation and triggers (rather than facilitates) processes beyond those usually involved in action observation. Moreover, COs with high goal affinity located close to the actor's dominant hand additionally engaged bilateral IFG, corroborating the view that IFG is critically involved in the integration of action steps under a common overarching goal. PMID- 29175613 TI - Chronic kidney disease after acute kidney injury associated with intravenous colistin use in survivors of severe infections: A comparative cohort study. AB - PURPOSE: The use of colistin for multi-drug resistant (MDR) infections has led to an increase of colistin-associated acute kidney injury (AKI). Nevertheless, information on long-term renal prognosis is scarce. We aimed to determine the predictors of chronic kidney disease (CKD) in survivors of MDR-infections with colistin-associated AKI. METHODS: A retrospective cohort of patients with colistin-associated AKI was compared with controls (survivors of severe infections who developed AKI matched by age, sex, diabetes, vancomycin exposure, and baseline kidney function). The primary outcome was the development of CKD after 6months of follow-up. RESULTS: From 2011 to 2015, 122 patients with MDR infections received colistin. Among 72 survivors, 29 (40%) had colistin associated AKI. After 6months, 22 of them (75%) progressed to CKD (G3 in 21/22) compared with 16 (27%) in 58 controls (P<0.001). Independent predictors of progression to CKD were colistin use [odds ratio (OR): 8.86; 95% CI: 2.8-27.8] and age (OR: 1.04, 95% CI: 1.01-1.07). In patients exposed to colistin, a total dose of colistin >5g was an independent predictor of progression to CKD (OR: 14.1, 95% CI: 2.6-75.7). CONCLUSION: Colistin-associated AKI had a substantial risk for the latter development CKD, and consequently, these patients should be tightly monitored.

Distinctive from other death mechanisms, ferroptosis requires cellular iron and lipid peroxides, and is dictated by specific cellular metabolic processes. Importantly, ferroptosis has been implicated in a plethora of human diseases. This paper reviews the recent advances and outstanding questions of the field by focusing on the role of cellular metabolism in ferroptosis. The relevance of ferroptosis to disease and therapy is also discussed. PMID- 29175615 TI - Characterization of tissue stiffness of the infraspinatus, erector spinae, and gastrocnemius muscle using ultrasound shear wave elastography and superficial mechanical deformation. AB - The aim of this study was to compare measurement methods of tissue stiffness using ultrasound shear wave elastography (SWE) and superficial mechanical deformation (MyotonPRO) in the infraspinatus, erector spinae, and gastrocnemius muscles. Thirty healthy volunteers were assessed during rest, 40% and 80% maximum voluntary isometric contraction (MVIC). Correlation of the two methods in the three muscle regions was significant (r = 0.23-0.71, p < .05), and strongest in the gastrocnemius. MyotonPRO reliability was excellent (ICC > 0.93), and demonstrated ability to discriminate between the three levels of muscle contraction. SWE demonstrated good reliability in the resting condition (ICC > 0.88), but lower during the 2 MVIC conditions. The utility of SWE during isometric contraction may be limited due to the inability to discriminate between 40% and 80% MVIC. PMID- 29175616 TI - Difficulty concentrating in generalized anxiety disorder: An evaluation of incremental utility and relationship to worry. AB - Difficulty concentrating is one of the most common diagnostic criteria across DSM 5 categories, especially within the emotional (mood- and anxiety-related) disorders. A substantial literature has characterized cognitive functioning in emotional disorders using objective (behavioral) computerized cognitive tasks. However, diagnoses are typically formed on the basis of subjective (self reported; clinician-rated) assessments of symptoms, and little is known about difficulty concentrating as a symptom. These questions are particularly important for generalized anxiety disorder (GAD), which has long been the subject of nosological debates, and for which several theoretical models that suggest a central role for cognitive impairments (including difficulty concentrating) in the maintenance of psychopathology have been proposed. The present study evaluated the incremental utility of difficulty concentrating and its relationship to worry and other symptoms in 175 GAD-diagnosed adults. Clinician assessed difficulty concentrating incrementally predicted clinician-rated GAD, anxiety, and depression severity even after other GAD symptoms were controlled. Consistent with theoretical models of GAD that propose a direct relationship between worry and cognitive impairment, difficulty concentrating mediated the relationship between trait worry and clinical severity. These findings suggest that difficulty concentrating has value as a diagnostic criterion and is a potential mechanism by which worry increases distress and impairment. PMID- 29175617 TI - Bioaccessibility of PBDEs present in indoor dust: A novel dialysis membrane method with a Tenax TA(r) absorption sink. AB - Human uptake of flame retardants (FRs) such as polybrominated diphenyl ethers (PBDEs) via indoor dust ingestion is commonly considered as 100% bioaccessible, leading to potential risk overestimation. Here, we present a novel in vitro colon extended physiologically-based extraction test (CE-PBET) with Tenax TA(r) as an absorptive "sink" capable to enhance PBDE gut bioaccessibility. A cellulose-based dialysis membrane (MW cut-off 3.5kDa) with high pH and temperature tolerance was used to encapsulate Tenax TA(r), facilitating efficient physical separation between the absorbent and the dust, while minimizing re-absorption of the ingested PBDEs to the dust particles. As a proof of concept, PBDE-spiked indoor dust samples (n=3) were tested under four different conditions; without any Tenax TA(r) addition (control) and with three different Tenax TA(r) loadings (i.e. 0.25, 0.5 or 0.75g). Our results show that in order to maintain a constant sorptive gradient for the low MW PBDEs, 0.5g of Tenax TA(r) are required in CE PBET. Tenax TA(r) inclusion (0.5g) resulted in 40% gut bioaccessibility for BDE153 and BDE183, whereas greater bioaccessibility values were seen for less hydrophobic PBDEs such as BDE28 and BDE47 (~60%). When tested using SRM 2585 (n=3), our new Tenax TA(r) method did not present any statistically significant effect (p>0.05) between non-spiked and PBDE-spiked SRM 2585 treatments. Our study describes an efficient method where due to the sophisticated design, Tenax TA(r) recovery and subsequent bioaccessibility determination can be simply and reliably achieved. PMID- 29175618 TI - Human footprint in Tibet: Assessing the spatial layout and effectiveness of nature reserves. AB - Humanity is causing dramatic changes to the Earth, and we may be entering a human dominated era referred to as the Anthropocene. Mapping the human footprint and assessing the spatial layout and effectiveness of protected areas facilitate sustainable development. As the core region of the third pole, Tibet is an important area for biodiversity and the provision of ecosystem services. In this study, five categories of human pressure were summed cumulatively to map the human footprint in Tibet for 1990 and 2010, and the spatial relationship between the human footprint and national and provincial nature reserves (NRs) in Tibet was analyzed. In addition, the human footprint map was also used to evaluate the effectiveness of national and provincial NRs for reducing the impact of human activities. A comprehensive assessment was undertaken for the Yarlung Zangbo Grand Canyon (YZGC) NR. There were several key findings from this study. First, the human footprint scores (HFS) in Tibet for 1990 and 2010 were low, and increased by 32.35% during 1990-2010, which was greater than the global value of 9% for 1993-2009, indicating that Tibet is seriously threatened by human pressure. Grazing intensity and road disturbance intensity contributed significantly to the increase in the HFS. Second, the average HFS for 1990 in NRs was lower than that for the entire Tibet, but the spatial layout and extent of some reserves (e.g., the Qomolangma NR) needs to be optimized further. Third, the establishment of NRs in Tibet was effective in reducing human activities. No leakage phenomena were identified in the regions surrounding the YZGC reserve. However, the management of NRs in Tibet is still challenging in terms of reducing human activities. PMID- 29175619 TI - Plant growth and arbuscular mycorrhizae development in oil sands processing by products. AB - Soil pollutants such as hydrocarbons can induce toxic effects in plants and associated arbuscular mycorrhizal fungi (AMF). This study was conducted to evaluate if the legume Lotus corniculatus and the grass Elymus trachycaulus and arbuscular mycorrhizal fungi could grow in two oil sands processing by-products after bitumen extraction from the oil sands in northern Alberta, Canada. Substrate treatments were coarse tailings sand (CTS), a mix of dry mature fine tailings (MFT) with CTS (1:1) and Pleistocene sandy soil (hydrocarbon free); microbial treatments were without AMF, with AMF and AMF plus soil bacteria isolated from oil sands reclamation sites. Plant biomass, root morphology, leaf water content, shoot tissue phosphorus content and mycorrhizal colonization were evaluated. Both plant species had reduced growth in CTS and tailings mix relative to sandy soil. AMF frequency and intensity in roots of E. trachycaulus was not influenced by soil hydrocarbons; however, it decreased significantly over time in roots of L. corniculatus without bacteria in CTS. Mycorrhizal inoculation alone did not significantly improve plant growth in CTS and tailings mix; however, inoculation with mycorrhizae plus bacteria led to a significantly positive response of both plant species in CTS. Thus, combined inoculation with selected mycorrhizae and bacteria led to synergistic effects. Such combinations may be used in future to improve plant growth in reclamation of CTS and tailings mix. PMID- 29175620 TI - Introducing the Green Protein Footprint method as an understandable measure of the environmental cost of anchovy consumption. AB - In a global framework of growing concern for food security and environmental protection, the selection of food products with higher protein content and lower environmental impact is a challenge. To assess the reliability of different strategies along the food supply chain, a measure of food cost through the environmental impact-protein content binomial is necessary. This study proposes a standardized method to calculate the Green Protein Footprint (GPF) index, a method that assesses both the environmental impact of a food product and its protein content provided to consumers. Life Cycle Assessment (LCA) was used to calculate the environmental impact of the selected food products, and a Life Cycle Protein Assessment (LCPA) was performed by accounting for the protein content along the supply chain. Although the GPF can be applied to all food chain products, this paper is focused on European anchovy-based products for indirect human consumption (fishmeal) and for direct human consumption (fresh, salted and canned anchovies). Moreover, the circular economy concept was applied considering the valorization of the anchovy residues generated during the canning process. These residues were used to produce fishmeal, which was employed in bass aquaculture. Hence, humans are finally consuming fish protein from the residues, closing the loop of the original product life cycle. More elaborated, multi ingredient food products (salted and canned anchovy products), presented higher GPF values due to higher environmental impacts. Furthermore, the increase of food loss throughout their life cycle caused a decrease in the protein content. Regarding salted and canned products, the packaging was the main hotspot. The influence of the packaging was evaluated using the GPF, reaffirming that plastic was the best alternative. These results highlighted the importance of improving packaging materials in food products. PMID- 29175621 TI - Effects of soil type and rainfall intensity on sheet erosion processes and sediment characteristics along the climatic gradient in central-south China. AB - Soil erosion poses a major threat to the sustainability of natural ecosystems. The main objective of this study was to investigate the effects of soil type and rainfall intensity on sheet erosion processes (hydrological, erosional processes and sediment characteristics) from temperate to tropical climate. Field plot experiments were conducted under pre-wetted bare fallow condition for five soil types (two Luvisols, an Alisol, an Acrisol and a Ferralsol) with heavy textures (silty clay loam, silty clay and clay) derived separately from loess deposits, quaternary red clays and basalt in central-south China. Rainfall simulations were performed at two rainfall intensities (45 and 90mmh-1) and lasted one hour after runoff generation. Runoff coefficient, sediment concentration, sediment yield rate and sediment effective size distribution were determined at 3-min intervals. Runoff temporal variations were similar at the high rainfall intensity, but exhibited a remarkable difference at the low rainfall intensity among soil types except for tropical Ferralsol. Illite was positively correlated with runoff coefficient (p<0.05). Rainfall intensity significantly contributed to the erosional process (p<0.001). Sediment concentration and yield rate were the smallest for the tropical Ferralsol and sediment concentration was the largest for the temperate Luvisol. The regimes (transport and detachment) limiting erosion varied under the interaction of rainfall characteristics (intensity and duration) and soil types, with amorphous iron oxides and bulk density jointly enhancing soil resistance to erosive forces (Adj-R2>88%, p<0.001). Sediment size was dominated by <0.1mm size fraction for the Luvisols and bimodally distributed with the peaks at <0.1mm and 1-0.5mm size for the other soil types. Exchangeable sodium decreased sediment size while rainfall intensity and clay content increased it (Adj-R2=96%, p<0.01). These results allow to better understand the climate effect on erosion processes at the spatial-temporal scale from the perspective of soil properties. PMID- 29175622 TI - Methylated arsenic species throughout a 4-m deep core from a free-floating peat island. AB - Arsenic (As) occurs in soils mostly in inorganic forms, whereas the organic forms usually occur only in trace amounts. Peatlands are waterlogged, generally anoxic, organic soils representing the first step in coal formation; the contribution of organic vs. inorganic As species in this environment has received little research attention. Here, 57 peat samples collected throughout a 4-m deep, free-floating mire were analysed for total As and for its organic species, including dimethylarsinic acid (DMA), methylarsonic acid (MA), trimethylarsine oxide (TMAO) and arsenobetaine (AB), by HPLC-ICPMS. Aqueous trifluoroacetic acid was used as extractant, resulting in an average extraction efficiency of almost 80%. Total As concentration throughout the profile ranged between 0.2 and 9.8mg/kgpeat (mean: 1.4+/-1.2mg/kgpeat). Organic As species (DMA+MA+TMAO+AB) accounted, on average, for 28+/-10% of total As (range: 6-51%), and for 37+/-13% of the extracted As (range: 7-64%). The relative abundance of organoarsenicals generally followed the order DMA>TMAO~MA?AB. A positive correlation (p<0.001) was found among all organic As compounds, whereas their concentrations were negatively correlated with total sulfur content. The submerged zone (bottom 300cm) showed average and maximum concentrations of organoarsenic compounds that were almost twice those found in the top 100cm. This study shows that significant proportions of methylated As species occur even in peat samples characterized by low total As concentration (mostly <2mg/kg). Finally, this work provides the first evidence of organoarsenic species in free-floating mires, i.e., a globally distributed but scarcely investigated ecosystem. PMID- 29175623 TI - Evidence from SINPHONIE project: Impact of home environmental exposures on respiratory health among school-age children in Romania. AB - BACKGROUND: Exposure to indoor air pollutants at home was found to be associated with respiratory diseases. As lifestyle changes with rapid economic growth in Romania, the aim of our study is to describe the characteristics of Romanian homes and their impact on children's respiratory health. METHODS: Self-reported information on respiratory symptoms was collected from 280 Romanian elementary school students in 2011, and the symptoms were categorized into allergy, asthma like, and flu-like symptoms. Home characteristics and demographic information were collected from questionnaires answered by parents. The association between home characteristics and respiratory health was assessed through multivariate logistic regression controlling for school indoor exposure. RESULTS: As compared to U.S. households, Romanian homes have a higher percentage of smokers, limited use of indoor climate control, and higher use of iron stoves. Exposure to environmental tobacco smoke was associated with both asthma and allergy symptoms. Additional risk factors identified for allergy symptoms include living in apartments, near pesticide sprayed areas, and the use of incense sticks. The significantly higher risk of flu-like symptoms was associated with mold and dampness issues, the use of air conditioner, gas heater/iron stove in children's bedroom. CONCLUSION: Our findings suggest that an increase in respiratory symptoms among Romanian school-age children can be partly related to their environmental exposure at home. Since most of the identified risk factors are preventable, our results provide critical information and evidence for policymakers, to develop target intervention and education strategies.

AB - The copper (Cu) content and isotopic composition were studied in soils and in pine tree rings at locations close to and far from the Cu smelter, located at Kitwe, Zambia. The soil in the remote area contained 25-75mgkg-1 Cu, whereas the soil close to the smelter contained 207-44,000mgkg-1 Cu. The delta65Cu at the remote area and close to the smelter varied in the range -0.40 to -0.110/00, and 0.44 to 0.010/00 respectively. The delta65Cu of the surface soil at both profiles (-0.44 to -0.400/00) is similar to the isotopic composition of the concentrates processed in the smelter (-0.75 to -0.450/00), i.e. both locations are affected by Cu ore dust. The increase in the delta65Cu in the direction towards the centre of the profile is caused by the oxidative dissolution of Cu(I) from ore minerals, during which heavier Cu is released. In deeper parts of the profile, there is a slight decrease in delta65Cu because of easier mobilisation of the lighter isotope. The tree rings at the two locations differ in the total contents and isotopic composition. At the less contaminated site, the Cu contents equal 0.4 to 1.1mgkg-1 while, at the polluted site, the Cu contents vary in the range 3 to 47mgkg-1. Whereas, at the less contaminated location, the tree rings are substantially enriched in lighter Cu (delta65Cu=-0.76 to -2.20/00), at locations close to the smelter the tree rings have an isotopic composition (-0.31 to 0.880/00) similar to that of the contaminated soil or processed ore. The isotopic compositions of the tree rings close to the smelter are affected particularly by interception of dust containing Cu ore. The delta13C in tree rings demonstrate the interconnection of acidification and Cu mobility.

AB - The lip scarification model of herpes simplex virus type 1 (HSV-1) infection can be used to study acute infection in the orofacial tissue and the establishment of viral latency. In this study, mice were inoculated with HSV-1 and tissue harvested during the acute phase of infection. Clinical presentation of classical open sores on the lip of infected mice was observed. We defined the histopathology, disease scores, and immune infiltration of the lower lip during the formation and resolution of the clinical lesions. Finally, the kinetics of virus replication and transport of viral genomes to the trigeminal ganglia were established. With the virological and pathologic events of acute infection defined, the HSV-1 lip scarification model can now be used to study primary HSV-1 infection, invasion of the trigeminal ganglia, and establishment of latency. PMID- 29175627 TI - Establishment of robust HCV genotype 4d, 5a, and 6a replicon systems. AB - Hepatitis C Virus (HCV) is a diverse human pathogen which displays ~15% divergence at the subtype level. To facilitate development of antivirals with pan genotype activity, we developed the first genotype 4d subgenomic replicon, as well as new replicons for genotypes 5a, and 6a. Adaptive mutations developed in these replicons differ greatly across genotypes. Their impacts on the replication capacity were tested using site-directed mutants. In the genotype 4d replicon, single mutations have moderate effect, but the double mutation NS4A-Q34R+NS5A S232G increased the replication capacity by 161-fold. These new stable replicon cell lines were used to determine the antiviral activity of HCV inhibitors. The NS3 protease inhibitor voxilaprevir, NS5A second generation inhibitor velpatasvir, and NS5B nucleoside analog inhibitor sofosbuvir, had similar antiviral activities across the different genotypes/subtypes tested, while the NS5A first generation inhibitor, ledipasvir, had very good antiviral activity against GT1, 4, 5, and 6 in vitro. PMID- 29175625 TI - Increased surface expression of HIV-1 envelope is associated with improved antibody response in vaccinia prime/protein boost immunization. AB - HIV-1 envelope (Env)-based vaccines have so far largely failed to induce antibodies that prevent HIV-1 infection. One factor proposed to limit the immunogenicity of cell-associated Env is its low level of expression on the cell surface, restricting accessibility to antibodies. Using a vaccinia prime/protein boost protocol in mice, we explored the immunologic effects of mutations in the Env cytoplasmic tail (CT) that increased surface expression, including partial truncation and ablation of a tyrosine-dependent endocytosis motif. After vaccinia primes, CT-modified Envs induced up to 7-fold higher gp120-specific IgG, and after gp120 protein boosts, they elicited up to 16-fold greater Tier-1 HIV-1 neutralizing antibody titers, although results were variable between isolates. These data indicate that the immunogenicity of HIV-1 Env in a prime/boost vaccine can be enhanced in a strain-dependent manner by CT mutations that increase Env surface expression, thus highlighting the importance of the prime in this vaccine format. PMID- 29175628 TI - Neuronal death/apoptosis induced by intracellular zinc deficiency associated with changes in amino-acid neurotransmitters and glutamate receptor subtypes. AB - In the present study, a model of zinc deficiency was developed by exposing primary neurons to an N,N,N',N'-Tetrakis (2-pyridylmethyl) ethylenediamine (TPEN) containing medium. The cell survival rate, apoptosis rate, intracellular and extracellular concentrations of 4 amino acids, and the expression of 2 glutamate receptor subtypes alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate receptor (GluR2)and N-methyl-d-aspartate receptor subtype 2B (NR2B) were evaluated in zinc deficient cells. The results revealed that zinc deficiency led to a decrease in cell viability and an increase in the apoptosis rate. Additionally, in cultured neurons, zinc deficiency led to an increase in the concentration of aspartic acid (Asp) and a decrease in the concentrations of glutamate (Glu), glycine (Gly), and gamma-aminobutyric acid (GABA). These changes were reversed by concurrent zinc supplementation. Furthermore, zinc deficiency led to an increase in the secreted amounts of Glu, Gly, and Asp but a decrease in secreted amounts of GABA, as measured using the concentrations of these amino acids in the cell-culture medium. These changes were partially reversed by zinc supplementation. Finally, zinc deficiency led to a significant decrease in GluR2 expression and an increase in NR2B expression in cultured neurons, whereas simultaneous treatment with zinc sulfate (ZnSO4) prevented these changes. These results suggest that zinc deficiency-induced neuronal death/apoptosis involves changes in the concentrations of 4 amino acid neurotransmitters and the expression of 2 glutamate receptor subtypes. PMID- 29175629 TI - Effects of polar substituents on the biological activity of thiosemicarbazone metal complexes. AB - In this paper, citronellal, vanillin and pyridoxal thiosemicarbazones were modified with polar substituents, namely ethylmorpholine and glucose, to increase their polarity and compare the effects of these moieties on their biological activity. Altogether, nine ligands were synthesized and for each of them also their copper(II) and nickel(II) complexes were prepared and used for the biological tests. Eventually, assays on proliferation inhibition were conducted using leukemic cell line U937, already used as a model for previous citronellal thiosemicarbazone tests. Biological tests were also performed on solid tumor cell line HT29. From the first screenings, two of the metal complexes showed remarkable interesting properties, and, therefore, were also tested for histosensitivity.

AB - PURPOSE: To prospectively investigate ultrasound-guided diffuse optical tomography (US-guided DOT) in predicting breast cancer response to neoadjuvant chemotherapy (NAC). MATERIALS AND METHODS: Eighty-eight breast cancer patients, with a total of 93 lesions, were included in our study. Pre- and post-last chemotherapy, size and total hemoglobin concentration (THC) of each lesion were measured by conventional US and US-guided DOT 1 day before biopsy (time point t0, THC THC0, SIZE S0) and 1 to 2 days before surgery (time point tL, THCL, SL). The relative changes in THC and SIZE of lesions after the first and last NAC cycles were considered as the variables DeltaTHC and DeltaSIZE. Receiver operating characteristic curve was performed to calculate DeltaTHC and DeltaSIZE cutoff values to evaluate pathologic response of 93 breast cancers to NAC, which were then prospectively used to predicate response of 61 breast cancers to NAC. RESULTS: The cutoff values of DeltaTHC and DeltaSIZE for evaluation of breast cancers NAC treatment response were 23.9% and 42.6%. At DeltaTHC 23.9%, the predicted treatment response in 61 breast lesions for the time points t1 to t3 was calculated by area under the curve (AUC), which were AUC1 0.534 (P=.6668), AUC2 0.604 (P=.1893), and AUC3 0.674(P =. 0.027), respectively; for DeltaSIZE 42.6%, at time points t1 to t3, AUC1 0.505 (P=.9121), AUC2 0.645 (P=.0115), and AUC3 0.719 (P=.0018). CONCLUSION: US-guided DOT DeltaTHC 23.9% and US DeltaSIZE 42.6% can be used for the response evaluation and earlier prediction of the pathological response after three rounds of chemotherapy.

AB - Amyloid precursor protein (APP) proteolysis is essential for the production of beta-amyloid peptides (Abeta) that form senile plaques in Alzheimer's disease (AD) brains. The beta-site amyloid protein precursor cleaving enzyme 1 (BACE1) is the rate limiting enzyme in the generation of Abeta from APP, inhibition of BACE1 is thereby considered as an attractive strategy for anti-AD drug discovery. Chitosan oligosaccharides (COS) has been shown to possess various biological activities. Here we investigated the potential inhibitory effect of COS on both BACE1 expression in HEK293 APPswe cells and BACE1 enzymatic activity in vitro. The results showed that COS (100-500MUg/ml) dose-dependently decreased the cell apoptosis, and potently repressed the secretion of both Abeta40 and Abeta42 as determined by ELISA. Moreover, treatment with COS resulted in a dramatic reduction in BACE1 mRNA and protein expression level, eIF2alpha phosphorylation as well as BACE1 enzymatic activity. Taken together, our findings indicate that COS can ameliorate Abeta-associated neurotoxicity, which may be, at least in part, attributable to reductions in BACE1 enzymatic activity and expression. PMID- 29175632 TI - Intravenous administration of the adeno-associated virus-PHP.B capsid fails to upregulate transduction efficiency in the marmoset brain. AB - Intravenous administration of adeno-associated virus (AAV)-PHP.B, a capsid variant of AAV9 containing seven amino acid insertions, results in a greater permeability of the blood brain barrier (BBB) than standard AAV9 in mice, leading to highly efficient and global transduction of the central nervous system (CNS). The present study aimed to examine whether the enhanced BBB penetrance of AAV PHP.B observed in mice also occurs in non-human primates. Thus, a young adult (age, 1.6 years) and an old adult (age, 7.2 years) marmoset received an intravenous injection of AAV-PHP.B expressing enhanced green fluorescent protein (EGFP) under the control of the constitutive CBh promoter (a hybrid of cytomegalovirus early enhancer and chicken beta-actin promoter). Age-matched control marmosets were treated with standard AAV9-capsid vectors. The animals were sacrificed 6 weeks after the viral injection. Based on the results, only limited transduction of neurons (0-2%) and astrocytes (0.1-2.5%) was observed in both AAV-PHP.B- and AAV9-treated marmosets. One noticeable difference between AAV PHP.B and AAV9 was the marked transduction of the peripheral dorsal root ganglia neurons. Indeed, the soma and axons in the projection from the spinal cord to the nucleus cuneatus in the medulla oblongata were strongly labeled with EGFP by AAV PHP.B. Thus, except for the peripheral dorsal root ganglia neurons, the AAV-PHP.B transduction efficiency in the CNS of marmosets was comparable to that of AAV9 vectors. PMID- 29175633 TI - DL-3-n-butylphthalide alleviates vascular cognitive impairment induced by chronic cerebral hypoperfusion by activating the Akt/Nrf2 signaling pathway in the hippocampus of rats. AB - Oxidative stress induced by chronic cerebral hypoperfusion (CCH) plays an important role in the pathogenesis of vascular cognitive impairment (VCI). The Akt/Nrf2 signaling pathway is one of the most important antioxidative stress pathways. To explore whether NBP (DL-3-n-butylphthalide) could alleviate VCI induced by CCH via activating the Akt/Nrf2 signaling pathway and modifying the levels of apoptosis-related proteins, adult male Sprague-Dawley rats were subjected to permanent occlusion of bilateral common carotid arteries (BCCAO) and treated either with vehicle or NBP (applied in two doses, 40 mg/kg and 80 mg/kg) while sham operated animals were treated with vehicle. Treatments were administered daily for 28 days. The obtained results indicate that both administrated doses of NBP significantly ameliorated the spatial learning and memory impairments as indicated by the Morris water maze test while Hematoxylin Eosin staining revealed that morphological defects in the CA1 area of hippocampus were improved. Moreover, NBP reversed the BCCAO-induced downregulation of investigated oxidative stress-related proteins (p-Akt, t-Nrf2, n-Nrf2 and HO-1) along with the upregulation of pro-apoptotic molecule, Bax and reduction of the expression of anti-apoptotic protein, Bcl-2. According to presented results, NBP may have a protective effect against cognitive and morphological impairments induced by CCH via activation of Akt/Nrf2 signaling pathway and inhibition of apoptotic cascade. PMID- 29175634 TI - Barrier-relevant crash modification factors and average costs of crashes on arterial roads in Indiana. AB - The objective of this study was to develop crash modification factors (CMFs) and estimate the average crash costs applicable to a wide range of road-barrier scenarios that involved three types of road barriers (concrete barriers, W-beam guardrails, and high-tension cable barriers) to produce a suitable basis for comparing barrier-oriented design alternatives and road improvements. The intention was to perform the most comprehensive and in-depth analysis allowed by the cross-sectional method and the crash data available in Indiana. To accomplish this objective and to use the available data efficiently, the effects of barrier were estimated on the frequency of barrier-relevant (BR) crashes, the types of harmful events and their occurrence during a BR crash, and the severity of BR crash outcomes. The harmful events component added depth to the analysis by connecting the crash onset with its outcome. Further improvement of the analysis was accomplished by considering the crash outcome severity of all the individuals involved in a crash and not just drivers, utilizing hospital data, and pairing the observations with and without road barriers along same or similar road segments to better control the unobserved heterogeneity. This study confirmed that the total number of BR crashes tended to be higher where medians had installed barriers, mainly due to collisions with barriers and, in some cases, with other vehicles after redirecting vehicles back to traffic. These undesirable effects of barriers were surpassed by the positive results of reducing cross median crashes, rollover events, and collisions with roadside hazards. The average cost of a crash (unit cost) was reduced by 50% with cable barriers installed in medians wider than 50ft. A similar effect was concluded for concrete barriers and guardrails installed in medians narrower than 50ft. The studied roadside guardrails also reduced the unit cost by 20%-30%. Median cable barriers were found to be the most effective among all the studied barriers due to the smaller increase in the crash frequency caused by these barriers and the less severe injury outcomes. More specifically, the occupants of vehicles colliding with near-side cable barriers tended to have less severe injuries than occupants of vehicles entering the median from median's farther side. The near-side cable barriers provided protection against rollover inside the median and against a potentially dangerous collision with or running over the median drain; therefore, the greatest safety benefit can be expected where cable barriers are installed at both edges of the median. The CMFs and unit crash costs for 48 road-barrier scenarios produced in this study are included in this paper. PMID- 29175635 TI - Correlates of fatality risk of vulnerable road users in Delhi. AB - Pedestrians, cyclists, and users of motorised two-wheelers account for more than 85% of all the road fatality victims in Delhi. The three categories are often referred to as vulnerable road users (VRUs). Using Bayesian hierarchical approach with a Poisson-lognormal regression model, we present spatial analysis of road fatalities of VRUs with wards as areal units. The model accounts for spatially uncorrelated as well as correlated error. The explanatory variables include demographic factors, traffic characteristics, as well as built environment features. We found that fatality risk has a negative association with socio economic status (literacy rate), population density, and number of roundabouts, and has a positive association with percentage of population as workers, number of bus stops, number of flyovers (grade separators), and vehicle kilometers travelled. The negative effect of roundabouts, though statistically insignificant, is in accordance with their speed calming effects for which they have been used to replace signalised junctions in various parts of the world. Fatality risk is 80% higher at the density of 50 persons per hectare (pph) than at overall city-wide density of 250 pph. The presence of a flyover increases the relative risk by 15% compared to no flyover. Future studies should investigate the causal mechanism through which denser neighborhoods become safer. Given the risk posed by flyovers, their use as congestion mitigation measure should be discontinued within urban areas. PMID- 29175636 TI - Effects of Rhizophagus clarus and P availability in the tolerance and physiological response of Mucuna cinereum to copper. AB - Arbuscular mycorrhizal fungi (AMF) improve plant ability to uptake P and tolerate heavy metals. This study aimed to evaluate the effect of available P and the inoculation of Rhizophagus clarus in a Cu-contaminated soil (i) on the activity of acid phosphatases (soil and plant), the presence of glomalin, and (ii) in the biochemical and physiological status of Mucuna cinereum. A Typic Hapludalf soil artificially contaminated by adding 60 mg kg-1 Cu was used in a 3 * 2 factorial design with three replicates. Treatments consisted of three P levels: 0, 40, and 100 mg kg-1 P. Each P treatment level was inoculated (+AMF)/non-inoculated (-AMF) with 200 spores of R. clarus per pot, and plants grown for 45 days. The addition of at least 40 mg kg-1 P and the inoculation of plants with R. clarus proved to be efficient to reduce Cu phytotoxicity and increase dry matter yield. Mycorrhization and phosphate fertilization reduced the activity of enzymes regulating oxidative stress (SOD and POD), and altered the chlorophyll a fluorescence parameters, due to the lower stress caused by available Cu. These results suggest a synergism between the application of P and the inoculation with R. clarus, favoring the growth of M. cinereum in a Cu-contaminated soil. This study shows that AMF inoculation represents an interesting alternative to P fertilization to improve plant development when exposed to excess Cu. PMID- 29175637 TI - Pectin and cellulose cell wall composition enables different strategies to leaf water uptake in plants from tropical fog mountain. AB - Leaf water uptake (LWU) has been observed in plants of different ecosystems and this process is distinct among different species. Four plant species from the Brazilian fog mountain fields were evaluated in order to detect if leaf water uptake capacity is related to the cell wall composition of leaf epidermis. LWU measurements and their relation to anatomical and biochemical traits were analyzed. Cell wall composition was verified through immunocytochemistry using monoclonal antibodies recognizing pectin compounds, and histochemistry with calcofluor white to track cellulose. Differences in LWU among the four species were clearly revealed. Two species presented higher maximum leaf water content and the lowest values of water absorption speed. The other two species presented opposite behavior, namely, low leaf water uptake and the highest values of water absorption speed. The anatomical traits associated with the cell wall composition corroborated the data on the different LWU strategies. The species with abundant detection of cellulose in their epidermal cell walls absorbed more water, but more slowly, while those with abundant detection of pectins absorbed water at a higher speed. These results indicate that cell wall composition regarding pectin and cellulose are significant for water uptake by the leaf epidermis. Pectin provides greater porosity and absorption speed, while cellulose provides greater hydrophilicity and greater water uptake capacity. Current data indicate that the composition of epidermal cell walls is a relevant trait for leaf water uptake. PMID- 29175638 TI - Links between gendered leisure time in childhood and adolescence and gendered occupational aspirations. AB - The world of work remains gender-segregated, and research is needed to identify factors that may give rise to women's and men's vocational choices. This study explored bidirectional relations between youth's gendered career aspirations and the proportions of youth's leisure time spent in stereotypically gendered activities and gendered social contexts. Participants were 203 youth (52% girls) from predominantly white, working and middle class families living in the US, who reported on their occupational aspirations and gendered interests in home interviews and on their daily activities in a series of 7 nightly phone interviews on two occasions, in middle childhood (Mage = 10.9) and in adolescence (Mage = 17.3). Path models revealed that aspirations predicted youth's time use more so than the reverse. Time in gendered social contexts, specifically time in female-only contexts, but not time in gender-typed activities, predicted career aspirations. Implications of these findings and suggestions for future research are discussed. PMID- 29175639 TI - Joint mechanical asymmetries during low- and high-demand mobility tasks: Comparison between total knee arthroplasty and healthy-matched peers. AB - Chronic inter-limb joint mechanical asymmetry has been reported following total knee arthroplasty (TKA) during low-demand mobility tasks such as level walking. However, no study has compared the inter-limb asymmetry during a high-demand mobility task such as decline walking. The objective of this cross-sectional study was to compare inter-limb asymmetry differences during both level and decline walking tasks at six months following TKA compared to asymmetry present in an age, gender, body mass index and activity level matched healthy cohort. Kinetic and kinematic gait analysis was conducted on 42 patients with TKA and 15 healthy-matched peers. Our inter-limb asymmetry results demonstrated significantly (p<0.05) greater combined limb support moment (MS) (mean differences [MD]=0.17; 95% CI=0.07, 0.22), knee extensor moment (MK) (MD=0.05; 95% CI=0.02, 0.09) and vertical ground reaction force (vGRF) (MD=0.03; 95% CI=0.01, 0.08) differences during decline walking compared to level walking in patients with TKA. Greater MS (MD=0.24; 95% CI=0.13, 0.35), MK (MD=0.08; 95% CI=0.03, 0.18), vGRF (MD=0.04; 95% CI=0.01, 0.08) and knee joint angle (MD=2.4; 95% CI=0.37, 3.80) differences were present in patients with TKA compared to healthy-matched peers during decline walking. Greater MS (MD=0.13; 95% CI=0.05, 0.20) and plantarflexor moment (MD=0.06; 95% CI=0.04, 0.16) differences were present in patients with TKA compared to healthy-matched peers during level walking. Post-TKA inter-limb asymmetry during level walking worsens as the physical demands of the task are increased. Thus, even patients with good self reported outcomes after TKA exhibit substantial deficits in their mobility reserves that could limit their independence and community mobility as they age. PMID- 29175640 TI - An exploratory study examining factors underpinning postural instability in older adults with idiopathic neck pain. AB - There is limited understanding of potential mechanisms underpinning postural control deficits in people with neck pain. This study examined several characteristics that might explain impaired postural stability in a group of older adults with neck pain, and compared the results in this cohort with that of asymptomatic controls. In this cross-sectional study we compared physical activity, lower limb motor and sensory function, vestibular and visual function, falls efficacy and dizziness handicap in 84 older adults with (n=35, age 69.6+/ 6.3) and without (n=49, age 69.4+/-4.7) idiopathic neck-pain. Additionally, dynamic balance was assessed using the dynamic gait index (DGI) and standard and wavelet analysis of static balance was computed after data capture. Physical activity levels, lower limb motor and sensory function, vestibular function and visual contrast sensitivity were not different between groups (p>0.05). The neck pain group demonstrated higher falls efficacy (p=0.01), greater levels of dizziness handicap (p<0.01), and higher CoP velocity measures in the moderate (1.56-6.25Hz) and low (0.39-1.56Hz) frequency bandwidths. Our results suggest that neck-pain induced postural control deficits in older adults may not be associated with the physical activity levels, lower limb motor and sensory function, or vestibular and visual function. Inferring from wavelet analysis results, we speculated that sensory re-weighting may have occurred to compensate for the deficits in neck proprioception. Further research is warranted to determine neck specific mechanisms underpinning postural control dysfunction in neck pain. PMID- 29175641 TI - Effect of tibia marker placement on knee joint kinematic analysis. AB - Variability of kinematic measures determined by different marker sets among sites participating in a collaborative study is necessary for determining the reliability of a multi-site gait analysis research. We compared knee kinematics based on different marker sets on the tibia, calculating by segmental optimization (SO) and multi-body optimization (MBO) methods respectively, in order to assess the effect of marker locations on the methods. 11 healthy subjects participated in the study with 33 markers attached to the lower extremity segments, and 4 groups were identified according to markers on the tibia. Knee joint kinematics during level walking were measured and then compared among the 4 groups using statistical parametric mapping. For SO method, the results showed that there were no significant differences in the knee joint angles when used different marker sets on the tibia. However, significant differences were found in the transverse plane kinematics for MBO method. It was concluded that MBO method was more likely to be influenced by different marker sets. More attention should be paid to marker sets, specifically for MBO method, when three-dimensional gait analysis data are shared and interpreted among sites for clinical decision-making. PMID- 29175642 TI - A simple and rapid measurement method of encapsulation efficiency of doxorubicin loaded liposomes by direct injection of the liposomal suspension to liquid chromatography. AB - A simple and rapid chromatographic measurement method for determining doxorubicin (DOX) encapsulation efficiency (EE) into PEGylated liposomes using nanoparticle exclusion chromatography (nPEC) was developed. In this work, Doxil(r) and two PEGylated liposomes spiked with DOX were employed as model liposomes, and unencapsulated DOX was measured by high performance liquid chromatography with diode-array detector using an N-vinylpyrrolidone modified nPEC column without any sample pretreatment. Only 5 MUL of an intact liposomal suspension and 3 min analysis time were required for the determination of the quantity of unencapsulated DOX. The method was validated in terms of linearity, accuracy, precision, and recovery in the range from 0.00-1.0 mg/mL (corresponding to 100 50% EE). Applicability of the method was confirmed using the measurement of time dependent DOX loading% into the liposomes with the remote loading method using an ammonium sulfate gradient. Furthermore, it was found that the peak area of DOX loaded liposomes in the chromatogram was proportional to DOX EE%. As this simple and rapid analytical method can measure the EE precisely, it is expected that this method will be applicable to the in-process control of liposome preparation manufacturing and the quality control of the liposome drug products. PMID- 29175643 TI - Sustained-release multiparticulates for oral delivery of a novel peptidic ghrelin agonist: Formulation design and in vitro characterization. AB - There is an impetus to provide appropriate sustained release oral delivery vehicles to protect biofunctional peptide loads from gastric degradation in vivo. This study describes the generation of a high load capacity pellet formulation for sustained release of a freely water-soluble dairy-derived hydrolysate, FHI 2571. The activity of this novel peptidic ghrelin receptor agonist is reported using in vitro calcium mobilization assays. Conventional extrusion spheronization was then used to prepare peptide-loaded pellets which were subsequently coated with ethylcellulose (EC) film coats using a fluid bed coating system in bottom spray (Wurster) mode. Aqueous-based EC coating dispersions produced mechanically brittle coats which fractured due to osmotic pressure build-up within pellets in simulated media. In contrast, an ethanolic-based EC coating solution provided robust, near zero-order release in both USP Type 1 and Type 4 dissolution studies. Interestingly, the functionality of aqueous-based EC film coats was restored by first layering pellets with a methacrylic acid copolymer (MA) subcoat, thereby hindering pellet core swelling in acidic media. Broadband Acoustic Resonance Dissolution Spectroscopy (BARDS) was utilised as a complementary technique to confirm the results seen in USP dissolution studies. Retention of activity of the ghrelinergic peptide hydrolysate in the final encapsulated product was confirmed as being greater than 80%. The described pellet formulation is amenable to oral dosing in small animal studies in order to assess in vivo efficacy of the whey-derived ghrelinergic hydrolysate. In more general terms, it is also suitable as a delivery vehicle for peptide-based bioactives to special population groups e.g paediatric and geriatric. PMID- 29175644 TI - Active freeze drying for production of nanocrystal-based powder: A pilot study. AB - Active Freeze Drying allows for producing lyophilised powders by progressive agitation of frozen blocks undergoing sublimation. One potential application of this process is the formulation design of unstable nanosuspensions for oral drug delivery, as here shown for nanocrystal-based ketoconazole powder. With this technique, a critical vapour flow needs to be achieved in order to obtain reasonable process yields (>78%). The size distribution of powder particles (median size between 21 and 44 MUm) was affected by the nanocrystal concentration and the drug-to-stabilizer ratio. This was assumed to be related to the mechanical strength of the solid network from which the powder particles break off. The adjustments of the drug-to-stabilizer ratio and the freezing procedure proved to play a major role in improving powder redispersibility. However, differences in powder redispersibility did not translate into significant changes in in-vitro dissolution rates. Active Freeze Drying has confirmed to be a promising tool to efficiently produce redispersible nanocrystal powders. PMID- 29175645 TI - Multivariate analysis for the optimization of microfluidics-assisted nanoprecipitation method intended for the loading of small hydrophilic drugs into PLGA nanoparticles. AB - Design of Experiment-assisted evaluation of critical process (total flow rate, TFR, flow rate ratio, FRR) and formulation (polymer concentration and structure, drug:polymer ratio) variables in a novel microfluidics-based device, a staggered herringbone micromixer (SHM), for poly(lactic-co-glycolic acid) copolymer (PLGA) nanoparticles (NPs) manufacturing was performed in order to systematically evaluate and mathematically describe their effects on NPs sizes and drug encapsulation; a small hydrophilic moiety, N-acetylcysteine, was chosen as challenging model drug. SHM-assisted nanoprecipitation method consistently yielded NPs with tailor made sizes (in the range of 100-900 nm) and polydispersity index range from 0.061 to 0.286. Significant effects on NPs sizes were highlighted for TFR and FRR: increasing TFR (from 5 to 15 mL/min) and decreasing FRR (from 1:1 to 1:5 v/v, acetonitrile: buffer) NPs with mean diameter <200 nm were obtained. SHM technique allowed for flexible, application-specific tuning of PLGA NPs size using organic solvents with relatively low toxicity (acetone, acetonitrile), varying aqueous phase composition (Tris buffer vs PVA aqueous solution) and PLGA characteristics (Mw ranging from 25-90 kDa, capped or un-capped PLGA, different lactide:glycolide molar ratio). A very satisfactory N Ac encapsulation efficiency (more than 67%) and a prolonged release (by 168 h) were achieved. PMID- 29175646 TI - Communication of genetic information to families with inherited rhythm disorders. AB - Given the dynamic nature of the electrical activity of the heart and ongoing challenges in the diagnostics of inherited heart rhythm disorders, genetic information can be a vital aspect of family management. Communication of genetic information is complex, and the responsibility to convey this information to the family lies with the proband. Current practice falls short, requiring additional support from the clinician and multidisciplinary team. Communication is a 2-part iterative process, reliant on both the understanding of the probands and their ability to effectively communicate with relatives. With the surge of high throughput genetic testing, results generated are increasingly complex, making the task of communication more challenging. Here we discuss 3 key issues. First, the probabilistic nature of genetic test results means uncertainty is inherent to the practice. Second, secondary findings may arise. Third, personal preferences, values, and family dynamics also come into play and must be acknowledged when considering how best to support effective communication. Here we provide insight into the challenges and provide practical advice for clinicians to support effective family communication. These strategies include acknowledging and managing genetic uncertainty, genetic counseling and informed consent, and consideration of personal and familial barriers to effective communication. We will explore the potential for developing resources to assist clinicians in providing patients with sufficient knowledge and support to communicate complex information to their at-risk relatives. Specialized multidisciplinary clinics remain the best equipped to manage patients and families with inherited heart rhythm disorders given the need for a high level of information and support. PMID- 29175647 TI - Gamma-glutamyl transferase and the risk of atherosclerosis and coronary heart disease. AB - Gamma-glutamyl transferase (GGT) is a ubiquitous cell surface enzyme that cleaves extracellular glutathione (G-SH) or other gamma-glutamyl compounds. GGT serves to increase the availability of amino acids, primarily cysteine, for intracellular G SH synthesis and plays a crucial role in maintaining G-SH homeostasis and defense against oxidative stress in organisms. Measurement of circulating GGT activity is widely used for the diagnosis of liver and obstructive biliary diseases and as an indicator of alcohol consumption. Epidemiological studies suggest an association between elevated GGT activity level and a risk of incident coronary heart disease (CHD) or CHD-related mortality. Elevated GGT activity level is associated with a plethora of cardio-metabolic risk factors, including traditional cardiovascular risk factors, metabolic syndrome, systemic inflammation, oxidative stress burden and various comorbidities that incur a negative impact on patient risk profile and prognosis. Experimental studies and studies of human atherosclerotic plaques have revealed not only the presence of catalytically active GGT in atherosclerotic plaques, but also a correlation between GGT activity and indices of plaque instability, suggesting direct involvement in the pathophysiology of atherosclerosis and related clinical events via promotion of pro-oxidant reactions by the enzyme. However, it remains unknown whether GGT plays a direct role in the pathophysiology of atherosclerosis and CHD or is merely a correlate of coexisting cardiovascular risk factors. The exact molecular mechanisms of GGT participation in atherosclerosis or CHD and assessment of GGT-lowering therapies, as well as their impact on clinical outcomes, remain to be investigated in longitudinal studies. PMID- 29175648 TI - Prognostic significance of neutrophil to lymphocyte ratio in patients with gastrointestinal stromal tumors: A meta-analysis. AB - BACKGROUND: The neutrophil to lymphocyte ratio (NLR) is reported to be a prognostic factor in multiple malignancies. However, its prognostic value in patients with gastrointestinal stromal tumors (GISTs) remains controversial. This study aims to evaluate the prognostic value of preoperative NLR in GISTs. METHODS: MEDLINE, EMBASE, and, Cochrane databases were searched until February 2017. Eligible articles were defined as studies assessing the prognostic role of preoperative NLR in GISTs. The end points were overall survival (OS), disease free survival (DFS), recurrence-free survival (RFS), and clinicopathological parameters. Pooled hazard ratios (HRs) or odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using fixed-effects/random-effects models. RESULTS: A total of eight studies comprising 1676 patients with GISTs were included. Elevated NLR had an association with decreased DFS/RFS (HR: 2.18, 95% CI: 1.30-3.67, P=0.003), but not OS (HR: 1.74, 95% CI: 0.63-4.84, P=0.29). The findings from most subgroup analyses were consistent with those from the overall analysis. Moreover, high NLR was significantly correlated with male, stomach lesion, tumor size (>5cm), tumor rupture (+), tumor recurrence (+), mitotic index (>5/50HPF), and NIH risk category (high/intermediate). CONCLUSIONS: Elevated preoperative NLR may be an unfavorable prognostic biomarker in patients with GISTs. PMID- 29175649 TI - Anti-Mullerian Hormone: genetic and environmental effects. AB - Anti-Mullerian hormone (AMH) is a homodimeric glycoprotein produced by granulosa cells of growing ovarian follicles. AMH appears to have an inhibitory effect on both primordial follicle recruitment and responsiveness of growing follicles to follicle-stimulating hormone (FSH). This hormone is considered to be a reliable marker of ovarian reserve; therefore, it is crucial to determine which factors influence AMH levels for prognostic and diagnostic purposes. In this review we intend to discuss the effect of genetic and environmental factors which may lead to AMH interindividual variability. PMID- 29175650 TI - The Asparagine-Rich Protein NRP Facilitates the Degradation of the PP6-type Phosphatase FyPP3 to Promote ABA Response in Arabidopsis. AB - The phytohormone abscisic acid (ABA) plays critical roles in abiotic stress responses and plant development. In germinating seeds, the phytochrome-associated protein phosphatase, FyPP3, negatively regulates ABA signaling by dephosphorylating the transcription factor ABI5. However, whether and how FyPP3 is regulated at the posttranscriptional level remains unclear. Here, we report that an asparagine-rich protein, NRP, interacts with FyPP3 and tethers FyPP3 to SYP41/61-positive endosomes for subsequent degradation in the vacuole. Upon ABA treatment, the expression of NRP was induced and NRP-mediated FyPP3 turnover was accelerated. Consistently, ABA-induced FyPP3 turnover was abolished in an nrp null mutant. On the other hand, FyPP3 can dephosphorylate NRP in vitro, and overexpression of FyPP3 reduced the half-life of NRP in vivo. Genetic analyses showed that NRP has a positive role in ABA-mediated seed germination and gene expression, and that NRP is epistatic to FyPP3. Taken together, our results identify a new regulatory circuit in the ABA signaling network, which links the intracellular trafficking with ABA signaling. PMID- 29175651 TI - Subclinical cerebrovascular disease in NAFLD without overt risk factors for atherosclerosis. AB - BACKGROUND AND AIMS: Non-alcoholic fatty liver disease is recognized not only as part of the metabolic syndrome but also as an independent predictor of cardiovascular disease. METHODS: In this study, NMR spectroscopy method, together with perfusion techniques, was used to detect subclinical brain vascular damage in subjects with NAFLD without overt atherosclerosis risk factors (i.e. hypertension, diabetes, hypercholesterolemia, obesity). RESULTS: The results suggest that subjects with histologically proven NAFLD have a reduced cerebral perfusion (CBFr) confined to limited brain areas, i.e., left semioval center and posterior cingulate cortex. No statistically significant differences in CBFr values were found, dividing the NAFLD cohort into subgroups, considering NAS score, presence/absence of NASH/fibrosis, and degree of steatosis. CONCLUSIONS: Our data suggest that NAFLD per se may be involved in cerebral atherosclerotic disease. It will be interesting to draw longitudinal studies to determine whether these changes could evolve in more serious cerebral injury. PMID- 29175652 TI - Serum amyloid A3 is pro-atherogenic. AB - BACKGROUND AND AIMS: Serum amyloid A (SAA) predicts cardiovascular events. Overexpression of SAA increases atherosclerosis development; however, deficiency of two of the murine acute phase isoforms, SAA1.1 and SAA2.1, has no effect on atherosclerosis. SAA3 is a pseudogene in humans, but is an expressed acute phase isoform in mice. The goal of this study was to determine if SAA3 affects atherosclerosis in mice. METHODS: ApoE-/- mice were used as the model for all studies. SAA3 was overexpressed by an adeno-associated virus or suppressed using an anti-sense oligonucleotide approach. RESULTS: Over-expression of SAA3 led to a 4-fold increase in atherosclerosis lesion area compared to control mice (p = 0.01). Suppression of SAA3 decreased atherosclerosis in mice genetically deficient in SAA1.1 and SAA2.1 (p < 0.0001). CONCLUSIONS: SAA3 augments atherosclerosis in mice. Our results resolve a previous paradox in the literature and support extensive epidemiological data that SAA is pro-atherogenic. PMID- 29175653 TI - IgM antibodies against phosphorylcholine promote polarization of T regulatory cells from patients with atherosclerotic plaques, systemic lupus erythematosus and healthy donors. AB - BACKGROUND AND AIMS: IgM antibodies against phosphorylcholine (anti-PC) are negatively associated with atherosclerosis, cardiovascular disease (CVD) and systemic lupus erythematosus (SLE), where the risk of CVD and atherosclerosis is high. We here study the effects of IgM anti-PC immune regulation. METHODS: Mononuclear leukocytes were isolated from peripheral blood (PBMC) obtained from healthy blood donors, six SLE patients with age- and sex-matched controls, and symptom-giving human atherosclerotic plaques. The proportion of Th17 (CD4+CCR6+) and Treg (CD4+CD25+CD127dim/-) cells was determined by flow cytometry in CD4+T cells after 6 days of culture with Th17 or Treg-polarizing cytokines, with PMA and Ionomycin stimulation. IgM anti-PC were extracted from total IgM, with flow through IgM as controls. Dendritic cells (DC) were differentiated from PBMC. Antibody peptide/protein characterization was done by a proteomics de novo sequencing approach. RESULTS: IgM anti-PC increased significantly the proportion of Tregs from healthy donors, SLE patients and atherosclerotic plaque cells while control antibodies did not. T cells from SLE patients had a significantly lower proportion of Tregs and a higher proportion of Th17 cells as compared to matched controls. IgM anti-PC, but not control antibodies, significantly reduced the production of IL-17 and TNF-alpha in cell cultures from SLE patients and atherosclerotic plaque cells. IgM anti-PC interacted with CD40 and kept DCs in an immature stage, potentially being tolerogenic. We observed differences in the IgM peptide expression levels in anti-PC compared to control antibodies. CONCLUSIONS: IgM anti-PC promote polarization of Tregs, which could represent a novel protective mechanism in atherosclerosis and autoimmune conditions as SLE. PMID- 29175654 TI - Arterial inflammation measured by 18F-FDG-PET-CT to predict coronary events in older subjects. AB - BACKGROUND AND AIMS: Although 18F-fluorodeoxyglucose (FDG) uptake has emerged as a sensitive and reliable marker of atherosclerotic inflammation, its additive predictive value for future coronary disease in older subjects is unknown. The aim of this study was to test the prognostic value of aortic inflammation detected via FDG-positron emission tomography (PET)-computed tomography (CT) in older subjects. METHODS: We retrospectively utilized the records of 309 subjects aged over 65 years, without a history of coronary artery disease, who underwent 18F-FDG-PET-CT mostly due to the clinical suspicion of cancer, but eventually turned out to be cancer-free. Target-to-background ratio (TBR) was calculated at the ascending aorta. The endpoint was occurrence of coronary heart disease (CHD) events. RESULTS: During a median follow-up of 3.9 years, 28 subjects experienced CHD events and 12 patients died due to non-CHD causes. The highest TBR tertile was associated with a high CHD event rate, accounting for death due to non-CHD causes as a competing risk (Gray test, p = 0.005). In a Fine and Gray competing risk proportional hazard regression model, TBR was associated with significantly high CHD events independently of FRS, with a hazard ratio (HR) of 1.19 per 0.1 TBR increase (p < 0.001). Likewise, a significant increase in the area under the curve (from 0.57 to 0.73, p = 0.028) and a significant improvement in net reclassification (0.42, p = 0.038) were observed when TBR was added to the model with FRS alone. CONCLUSIONS: In older subjects with no history of malignant disease or overt coronary artery disease, arterial inflammation evaluated by FDG uptake provides information on future occurrence of coronary artery events. PMID- 29175655 TI - Thrombogenicity and central pulse pressure to enhance prediction of ischemic event occurrence in patients with established coronary artery disease: The MAGMA ischemia score. AB - BACKGROUND AND AIMS: Conventional cardiovascular risk estimators based on clinical demographics have limited prediction of coronary events. Markers for thrombogenicity and vascular function have not been explored in risk estimation of high-risk patients with coronary artery disease. We aimed to develop a clinical and biomarker score to predict 3-year adverse cardiovascular events. METHODS: Four hundred eleven patients, with ejection fraction >=40% undergoing coronary angiography, and found to have a luminal diameter stenosis >=50%, were included in the analysis. Thrombelastography indices and central pulse pressure (CPP) were determined at the time of catheterization. RESULTS: We identified predictors of death, myocardial infarction (MI) or stroke and developed a numerical ischemia risk score. The primary endpoint of cardiovascular death, MI or stroke occurred in 22 patients (5.4%). The factors associated with events were age, prior PCI or CABG, diabetes, CPP, and thrombin-induced platelet-fibrin clot strength, and were included in the MAGMA-ischemia score. The MAGMA-ischemia score showed a c-statistic of 0.85 (95% Confidence Interval [CI] 0.80-0.87; p<0.001) for the primary endpoint. In the subset of patients who underwent revascularization, the c-statistic was 0.90 (p<0.001). Patients with MAGMA ischemia score greater than 5 had highest risk to develop clinical events, hazard ratio for the primary endpoint: 13.9 (95% CI 5.8-33.1, p<0.001) and for the secondary endpoint: 4.8 (95% CI 2.3-9.6, p<0.001). When compared to previous models, the MAGMA-ischemia score yielded a higher discrimination. CONCLUSIONS: Inclusion of CPP and assessment of thrombogenicity in a novel score for patients with documented CAD enhanced the prediction of events. PMID- 29175656 TI - Pyranose ring puckering in aldopentoses, ketohexoses and deoxyaldohexoses. A molecular dynamics study. AB - Conformation of monosaccharides, including the ring shape, has for years been the subject of intensive research. Although d-aldohexopyranoses are the most extensively studied pyranoses, there also exist other groups of saccharides that contain analogous chemical system of the six-membered ring. Here we describe in details the results of the molecular dynamics-based conformational analysis concerning a series of pyranoses, namely: d-aldopentoses, d-ketohexoses as well as deoxy- (d-quinovose, l-fucose, l-rhamnose) and dideoxy- (abequose, paratose, tyvelose, digitoxose) derivatives of aldohexoses. By using the carbohydrate dedicated GROMOS 56a6CARBO force field, we determined the conformational properties of both the lactol and hydroxymethyl groups as well as the anomeric populations for all considered compounds. The orientation of the lactol group follows the trend expected on the basis of the exo-anomeric effect for all compounds whereas the conformation of the hydroxymethyl group in d-ketohexoses is represented by the two gauche (with respect to the ring oxygen atom) rotamers. The special emphasis is put on the ring-inversion properties studied in the context of both the full chair-chair inversion and the chair-boat/skew-boat rearrangement. The calculated ring-distortion energies, compared with those obtained for regular d-aldohexopyranoses allowed for estimating the influence of particular substituents on the ring flexibility. Overall, such influence is correlated with the dimension of the substituent and its orientation but is limited to the case of the chair-chair inversion whereas the chair-to-boat/skew boat rearrangement exhibits roughly the same properties for all pyranoses. For all d-aldopyranoses the alpha anomers exhibit lower ring-inversion free energies in comparison to the beta anomers whereas this trend is inverted in the case of d ketohexopyranoses. PMID- 29175657 TI - A combined variable temperature 600 MHz NMR/MD study of the calcium release agent cyclic adenosine diphosphate ribose (cADPR): Structure, conformational analysis, and thermodynamics of the conformational equilibria. AB - A combined variable temperature 600 MHz NMR/molecular dynamics study of the Ca2+ release agent cyclic adenosine 5'-diphosphate ribose (cADPR) was conducted. In addition to elucidating the major and minor orientations of the conformationally flexible furanose rings, gamma- (C4'-C5'), and beta- (C5'-O5') bonds, the thermodynamics (DeltaHo, DeltaSo) associated with each of these conformational equilibria were determined. Both furanose rings were biased towards a south conformation (64-74%) and both beta-bonds heavily favored trans conformations. The R-ring gamma-bond was found to exist almost exclusively as the gamma+ conformer, whereas the A-ring gamma-bond was a mixture of the gamma+ and gammat conformers, with the trans conformer being slightly favored. Enthalpic factors accounted for most of the observed conformational preferences, although the R ring furanose exists as its major conformation based solely on entropic factors. There was excellent agreement between the NMR and MD results, particularly with regard to the conformer identities, but the MD showed a bias towards gamma+ conformers. The MD results showed that both N-glycosidic chi-bonds are exclusively syn. Collectively the data allowed for the construction of a model for cADPR in which many of the conformationally flexible units in fact effectively adopt single orientations and where most of the conformational diversity resides in its A-ring furanose and gamma-bond. PMID- 29175658 TI - Sonformational study of persulfated propyl glucuronide. AB - Glucuronic acid is an important constituting block of biologically active glycosaminoglycans where it can be present in non-sulfated, mono-sulfated and di sulfated forms. Despite that some investigators reported previously that the exhaustively sulfated glucuronic acid moiety was characterized with unusual 1H-1H coupling constants and some times chemical shifts, these were just qualitative studies in which their authors suggested that the mentioned deviations in NMR spectra might mean complete inversion of the normal D-pyranoside chair conformation 4C1 to 1C4. Herein we outline a detailed conformational investigation showing that the distortion in the pyranoside ring of the persulfated glucuronic acid cannot be described simply with 4C1<->1C4 inversion. Instead, the experimental NOE data clearly indicate that two skew-boat conformers, OS2 and 3S1, provide significant contribution to the conformational equilibrium. PMID- 29175659 TI - DIDMH in combination with triflic acid - A new promoter system for thioglycoside glycosyl donors. AB - We have explored the possibility of using 1,3-diiodo-5,5-dimethylhydantoin (DIDMH) as an alternative to N-iodosuccinimide (NIS) for activation of glycosyl donors of the thioglycoside type in various glycosylation reactions. DIDMH was found to match NIS when it comes to the capability to activate thioglycosides and provide glycosylation products in good yields. Notably, with the two equivalents of reactive iodonium ions per molecule of DIDMH less mass needs to be added making this activator a more atom economically alternative to NIS. Furthermore, DIDMH was found to be stable upon storage for weeks and comparably priced to NIS. With this knowledge in hand we therefore encourage the carbohydrate community to consider using DIDMH for activation of thioglycosides in glycosylation reactions. PMID- 29175660 TI - Chemo-enzymatic synthesis of the glucagon containing N-linked oligosaccharide and its characterization. AB - The chemo-enzymatic synthesis of an artificially N-glycosylated derivative of glucagon, a peptide hormone that regulates the blood sugar level, is described. We synthesized the glycosylated glucagon by chemical synthesis of an N acetylglucosaminyl peptide and enzymatic transfer of an oligosaccharide using the transglycosylation activity of the glycosynthase-like mutant of Mucor hiemalis endo-beta-N-acetylglucosaminidase (Endo-M) and sialo-oligosaccharide oxazoline as a donor substrate. The sialo-oligosaccharide-attached glucagon synthesized showed high resistance against protease degradation and stimulated the release of glucose from mouse hepatocytes when added to cells. The synthetic glucagon showed slightly higher activity than native glucagon and has potential as a therapeutic agent for treating diabetic patients.

AB - INTRODUCTION: Present knowledge concerning potential associations between comorbidities and the fatality of a first myocardial infarction (MI) is limited. AIM: To identify comorbidities in 45-70-year-old individuals who suffered a first MI and died within 7 days in Stockholm County from 1992-1994. In addition, to assess how each of the comorbidities identified, as well as the number of hospitalizations during the 10-year period prior to the MI, was associated with MI fatality. METHODS: The data collected on our inception cohort of 1984 first MI, of which 524 were fatal within 7 days, were primarily self-reported, proxy reported by questionnaire and/or extracted from comprehensive national registers. Comorbidities among fatal cases with a prevalence >2% were identified. Risk ratios (with 95% confidence intervals) for the association of MI fatality with number of prior hospitalizations and specific comorbidities were calculated using binomial regression with log link. A structured review of autopsy reports on fatal cases was performed in order to identify additional indicators of comorbidities. RESULTS: After adjusting for sex, age and disposable income, the number of previous hospitalizations was associated with 7-day MI fatality. Of the comorbidities identified as prevalent in fatal cases, the following were associated with 7-day fatality in crude analysis: epilepsy, heart failure, stroke, alcoholism, cancer, renal diseases, asthma, psychiatric diseases, diabetes, and rheumatoid arthritis. Indicators of comorbidities identified from autopsy data included a silent MI, severe atherosclerosis of the abdominal aorta, and hepatic steatosis. Adjustments for sex and age (although not possible for epilepsy and alcoholism), did not substantially alter results. CONCLUSIONS: Our current findings indicate that in connection with a first MI, particular attention should be paid to those with repeated prior hospitalizations and/or epilepsy, heart failure, stroke, alcoholism, cancer, renal diseases, asthma, psychiatric diseases, diabetes and rheumatoid arthritis. PMID- 29175663 TI - Changes in neurofilament 200 and tyrosine hydroxylase expression in the cardiac innervation of diabetic rats during aging. AB - Changes in sensory and sympathetic innervation during diabetes mellitus (DM) can be a predictor of arrhythmias, silent myocardial ischemia, and chronic heart failure, but knowledge about these changes is still unsatisfactory. We analyzed whether prolonged DM induces changes in density of sensory and sympathetic nerve terminals of rat's heart and whether it contributes to cardiomyopathy during aging. DM was induced by i/p injecting 55 mg/kg streptozotocin to male Sprague Dawley rats, while a control group received a citrate buffer. DM in the rats was validated by measuring blood glucose level. Animals were sacrificed after 2 weeks, 2 months, 6 months, and 12 months. Five areas of cardiac sections were analyzed. Antibodies raised against tyrosine hydroxylase (TH) and neurofilament 200 kDa (NF 200) were used to detect sympathetic and sensory fibers. TH immunoreactive fiber density increased in DM groups 2 weeks after induction, reaching a peek after 2 months, while in the later stages of DM (6 and 12 months), there was no significant difference compared to control. NF 200 immunoreactive fiber density increased 2 weeks after induction compared to control. There was no consistent pattern of change during the given period in both the DM or control groups. In the DM group, we found thickening of the left ventricle wall (P<.05) as the sign of cardiomyopathy. Our findings suggest that hyperglycemia as a hallmark of DM in early stages can lead to proliferation of sympathetic and sensory nerve terminals. This finding can contribute to a better understanding of the occurrence of arrhythmias and silent myocardial ischemia in DM.

AB - There is no previous study in the literature that has examined the relationship between circulating vitamin K1 (VK1) with glycemic status in type 2 diabetes (T2D). Moreover, scientific explanation for the beneficial role of VK1 supplementation in lowering glycemia in diabetes is yet to be determined. This study for the first time demonstrated that circulating VK1 was significantly lower in T2D patients compared to age-matched control subjects, and VK1 levels in T2D were significantly and inversely associated with fasting glucose and insulin resistance [homeostatic model assessment of insulin resistance (HOMA-IR)], which suggest that boosting plasma VK1 may reduce the fasting glucose and insulin resistance in T2D patients. Using high-fat-diet-fed T2D animal model, this study further investigated the positive effect of VK1 supplementation on glucose metabolism and examined the underlying molecular mechanism. Results showed that VK1 supplementation [1, 3, 5 MUg/kg body weight (BW), 8 weeks] dose dependently improved the glucose tolerance; decreased BW gain, fasting glucose and insulin, glycated hemoglobin, HOMA-IR and cytokine secretion (monocyte chemoattractant protein-1 and interleukin-6); and regulated the signaling pathway of hepatic glucose metabolism [sirtuin 1 (SIRT1)/AMP-activated protein kinase (AMPK)/phosphoinositide 3-kinase/phosphatase and tensin homolog/glucose transporter 2/glucokinase/glucose 6 phosphatase], lipid oxidation (peroxisome proliferator-activated receptor alpha/carnitine palmitoyltransferase 1A) and inflammation (nuclear factor kappa B) in T2D mice. Comparative signal silencing studies also depicted the role of SIRT1/AMPK in mediating the effect of VK1 on glucose metabolism, lipid oxidation and inflammation in high-glucose-treated cultured hepatocytes. In conclusion, this study demonstrates that circulating VK1 has a positive effect on lowering fasting glucose and insulin resistance in T2D via regulating SIRT1/AMPK signaling pathway. PMID- 29175668 TI - Grape seed procyanidin extract ameliorates lead-induced liver injury via miRNA153 and AKT/GSK-3beta/Fyn-mediated Nrf2 activation. AB - Lead-induced hepatotoxicity is characterized by an extensive oxidative stress. Grape seed procyanidin extract (GSPE) possesses abundant biological activities. Herein, we investigated the protective role of GSPE against lead-induced liver injury and determined the potential molecular mechanisms. In vivo, rats were treated with/without lead acetate (PbAc) (0.05%, w/v) in the presence/absence of GSPE (200 mg/kg). In vitro, hepatocytes were pretreated with/without GSPE (100 MUg/ml) in the presence/absence of PbAc (100 MUM). PbAc administration to rats resulted in anemia, liver dysfunction, lead accumulation in the bone and liver, oxidative stress, DNA damage and apoptosis. GSPE significantly attenuated these adverse effects, except lead accumulation in liver. GSPE also decreased the expression of miRNA153 and increased the translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) and levels of its downstream protein, and protein kinase B (AKT) phosphorylation in PbAc-induced liver injury. In primary hepatocytes treated with PbAc, GSPE increased hepatocyte viability and decreased lactate dehydrogenase release and reactive oxygen species levels. Dietary GSPE attenuated PbAc-induced liver injury in rats via an integrated mechanism associated with the miRNA153 and AKT/glycogen synthase kinase 3 beta/Fyn-mediated Nrf2 activation. PMID- 29175669 TI - Euterpe oleracea Mart. (acai) seed extract associated with exercise training reduces hepatic steatosis in type 2 diabetic male rats. AB - Type 2 diabetes mellitus contributes to an increased risk of metabolic and morphological changes in key organs, such as the liver. We aimed to assess the effect of the acai seed extract (ASE) associated with exercise training on hepatic steatosis induced by high-fat (HF) diet plus streptozotocin (STZ) in rats. Type 2 diabetes was induced by feeding rats with HF diet (55% fat) for 5 weeks, followed by a single low dose of STZ (35 mg/kg i.p.). Control and diabetic groups were subdivided into four groups that were fed with standard chow diet for 4 weeks. Control (C) group was subdivided into Sedentary C, Training C, ASE Sedentary C and ASE Training C. Diabetic (D) group was subdivided into Sedentary D, Training D, ASE Sedentary D and ASE Training D. ASE (200 mg/kg/day) was administered by intragastric gavage, and the exercise training was performed on a treadmill (30 min/day; 5 days/week). Treatment with ASE associated with exercise training reduced the blood glucose (70.2%), total cholesterol (81.2%), aspartate aminotransferase (51.7%) and hepatic triglyceride levels (66.8%) and steatosis (72%) in ASE Training D group compared with the Sedentary D group. ASE associated with exercise training reduced the hepatic lipogenic proteins' expression (77.3%) and increased the antioxidant defense (63.1%), pAMPK expression (70.2%), cholesterol transporters (71.1%) and the pLKB1/LKB1 ratio (57.1%) in type 2 diabetic rats. In conclusion, ASE treatment associated with exercise training protects against hepatic steatosis in diabetic rats by reducing hepatic lipogenesis and increasing antioxidant defense and cholesterol excretion. PMID- 29175670 TI - ApoE is a major determinant of hepatic bile acid homeostasis in mice. AB - Apolipoprotein E (ApoE) plays a central role in lipid transport and cholesterol metabolism, with surplus cholesterol being removed from the liver through bile acid (BA) synthesis. Furthermore, BAs are of critical importance in fat absorption by forming intestinal lipid-bile salt mixed micelles. To define ApoE's role in BA homeostasis, the metabolism of cholesterol and BA was investigated in liver tissue and gallbladder bile of ApoE-deficient mice given a chow or high cholesterol/high-fat diet (HCHF) diet for 6 months. When compared to wild-type mice, muricholic acid (MCA) and chenodeoxycholic acid (CDCA) increased approximately 15-, 82-, 22- and 38-fold, respectively, in hepatic tissue of ApoE deficient mice given a chow or HCHF diet. Moreover, ApoE-deficient mice on an HCHF diet increased the amounts of hepatic free cholesterol, MCA and CDCA by 61%, 61% and 50% (P<.05). Conversely, total cholesterol and cholesterol esters were unchanged, and the bile acids taurohyodeoxycholic acid, taurodeoxycholic acid and hyodeoxycholic acid decreased to one third as compared to the chow diet (P<.05). Additionally, quantitative reverse-transcription polymerase chain reaction assays revealed induced expression of the bile acid receptor (Fxr) and associated transcription factors, i.e.Fxr, Lrh, Lxra and Srebp1c. Transcript expression of Cyp2a12, Cyp1b1, Cyp2e1, Cyp3a16 and Cyp4a10 was also induced. Note that Cyp4a10 catalyzes omega-hydroxylation of arachidonic acid to epoxy- and hydroxyeicosatrienoic acids to control vascular tone. Altogether, MCA and CDCA synthesis is selectively induced in ApoE-deficient mice. These hydrophilic BAs alter micellar size and structure to lower intestinal cholesterol solubilization. Furthermore, CDCA and MCA are potent FXR agonist and antagonist, respectively, and function in a regulatory loop to mitigate impaired ApoE function.

AB - Recent evidence has suggested that dietary polyunsaturated fatty acids (PUFAs) modulate inflammation; however, few studies have focused on the pathobiology of PUFA using isocaloric and isolipidic diets and it is unclear if the associated pathologies are due to dietary PUFA composition, lipid metabolism or obesity, as most studies compare diets fed ad libitum. Our studies used isocaloric and isolipidic liquid diets (35% of calories from fat), with differing compositions of omega (omega)-6 or long chain (Lc) omega-3 PUFA that were pair-fed and assessed hepatic pathology, inflammation and lipid metabolism. Consistent with an isocaloric, pair-fed model we observed no significant difference in diet consumption between the groups. In contrast, the body and liver weight, total lipid level and abdominal fat deposits were significantly higher in mice fed an omega-6 diet. An analysis of the fatty acid profile in plasma and liver showed that mice on the omega-6 diet had significantly more arachidonic acid (AA) in the plasma and liver, whereas, in these mice omega-3 fatty acids such as eicosapentaenoic acid (EPA) were not detected and docosahexaenoic acid (DHA) was significantly lower. Histopathologic analyses documented that mice on the omega-6 diet had a significant increase in macrovesicular steatosis, extramedullary myelopoiesis (EMM), apoptotic hepatocytes and decreased glycogen storage in lobular hepatocytes, and hepatocyte proliferation relative to mice fed the Lc omega-3 diet. Together, these results support PUFA dietary regulation of hepatic pathology and inflammation with implications for enteral feeding regulation of steatosis and other hepatic lesions. PMID- 29175673 TI - Astrocytic gamma-aminobutyric acid (GABA) transporters mediate guanidinoacetate transport in rat brain. AB - Guanidinoacetate (GAA) is a biosynthetic precursor of creatine, which plays a critical role in homeostasis of high-energy phosphates in the brain, but cerebral accumulation of GAA leads to neurological complications, such as epilepsy and seizures. The purpose of the present study was to clarify the contribution of the gamma-aminobutyric acid (GABA) transport systems to GAA transport in astrocytes by means of uptake studies in rat brain slices, primary astrocyte cultures and Chinese hamster ovary (CHO) cells expressing human GABA transporters (GATs). GAA uptake by rat brain slices was Na+- and Cl--dependent, and GABA-sensitive. The inhibitory effect of GABA, a common substrate of GATs, on GAA uptake by the brain slices was similar to that of beta-alanine, a selective substrate of GAT2/Slc6a13, GAT3/Slc6a11, and taurine transporter (TauT)/Slc6a6. Taurine, a high-affinity substrate of TauT/Slc6a6, exhibited a lesser inhibitory effect. In contrast, betaine, a substrate of betaine-GABA transporter 1 (BGT1)/Slc6a12, and creatine, a substrate of creatine transporter (CRT)/Slc6a8, had little inhibitory effect. A similar inhibition profile was observed in primary-cultured astrocytes. CHO cells expressing human GAT2/SLC6A13, GAT3/SLC6A11 and BGT1/SLC6A12 exhibited GAA transport, whereas CHO cells expressing GAT1/SLC6A1 did not. The Michaelis Menten values in CHO cells expressing GAT2/SLC6A13 and GAT3/SLC6A11 were similar to those in primary-cultured astrocytes. Overall, our results suggest that astrocytic GAT2/Slc6a13 and GAT3/Slc6a11 play major roles in GAA uptake as regulatory mechanisms of GAA in rat brain, while TauT/Slc6a6, BGT1/Slc6a12, and CRT/Slc6a8 make relatively small contributions.

AB - Prenatal morphine exposure causes a variety of neurobehavioral alterations observed in later life. The present study investigated the effects of postnatal exercise and enriched environment (EE) on alterations in water maze learning and hippocampal long-term potentiation (LTP) and brain derived neurotrophic factor (BDNF) levels induced by exposure to morphine during prenatal period in rats. On gestation days 11-18, pregnant rats were injected twice daily with saline or morphine. Offspring were subjected to postnatal exercise and EE for 30 days and afterward, spatial learning and hippocampal LTP and BDNF levels were investigated. Prenatal morphine-exposure impaired the spatial learning and hippocampal LTP in both male and female offspring. Interestingly, postnatal exercise and EE increased performance in the water maze and improved LTP in both prenatally saline and morphine-exposed male and female rats. Prenatal morphine exposure also caused a reduction in the hippocampal BDNF levels in the female, but not male rats, and postnatal exercise and EE alleviated this deficit. Our results demonstrate that postnatal exercise and EE can improve deficits in water maze learning and hippocampal LTP and BDNF levels caused by prenatal morphine exposure.

AB - Trichomonas vaginalis is a major non-viral sexually-transmitted infection resulted into serious obstetrical and gynecological troubles. The increasing resistance to nitroimidazole therapy and recurrence makes it crucial to develop new drugs against trichomoniasis. Over the past few years, a large number of research articles highlighting the synthetic and natural product research to combat Trichomonas vaginalis have been published. Electronic databases were searched to collect all data from the year 2006 through June 2017 for anti Trichomonas activity potential of synthetic and natural products. This review article put together the synthetic and natural product research to find out an effective metronidazole alternative to cure trichomoniasis. PMID- 29175676 TI - Meta-analysis of the efficacy of modafinil versus placebo in the treatment of multiple sclerosis fatigue. AB - BACKGROUND: Clinical trials examining the therapeutic benefit of modafinil in MS fatigue provide conflicting data. The goal of this study was to systematically evaluate the efficacy of modafinil using a meta-analytic method. METHODS: A systematic literature search was performed on published peer reviewed articles from 2000 to 2017 using the Cochrane Library, PubMed, and EMBASE. This review included double blind, randomized controlled trials, which evaluated modafinil in MS fatigue. The primary outcome measure was the estimated treatment difference in the Modified Fatigue Impact Scale score (MFIS) and Fatigue Severity Scale score (FSS). A secondary outcome measure was the estimated treatment difference in the Symbol Digit Modalities Test (SDMT). RESULTS: A total of 303 patients from five randomized controlled trials were included in the analyses. Modafinil was superior to placebo with an estimated treatment difference according to the MFIS (MD = -5.27, 95% CI: -8.51 to -2.03, P = 0.001). For the FSS, there was no significant difference between the two groups (MD = 2.50, 95%CI: -0.70 to 5.70, P = 0.13). For the secondary outcome, there was no significant difference between groups studied using the SDMT (MD = 0.23, 95% CI: -0.25 to 0.71, P = 0.35). CONCLUSIONS: Our meta-analysis showed that modafinil was an effective pharmacologic therapy for MS fatigue. Additional research is required to determine optimal dosing and treatment schedules. PMID- 29175677 TI - Efficacy and safety of regorafenib in the treatment of metastatic colorectal cancer: A systematic review. AB - PURPOSE: Despite advances in the treatment of colorectal cancer, third-line treatment options are still limited. Regorafenib was approved in 2012 for the treatment of patients with metastatic colorectal cancer previously treated with approved standard therapy. The purpose of this review is to present existing clinical data on regorafenib. METHOD: We systematically searched the PubMed and Embase databases, as well as ASCO and ESMO conference abstracts, for studies in English including >=30 patients, evaluating the efficacy and safety of regorafenib in patients with metastatic colorectal cancer. A meta-analysis was conducted on the published, randomized phase III trials. RESULTS: 24 eligible studies were included. In two phase III trials, regorafenib significantly increased overall survival (OS), progression free survival (PFS), and disease control rate when compared to placebo. Survival benefits of 1.4 and 2.5 months were presented. The meta-analysis indicated a significant greater treatment effect on OS (hazard ratio 0.67) and PFS (hazard ratio 0.40), compared to placebo. The non-randomized studies mostly supported these results. The most frequently reported adverse events were hand-foot-skin reaction (25%-86%), hypertension (11%-47%) and fatigue (2%-73%). CONCLUSION: Large phase III randomized trials indicate that regorafenib provides a benefit in OS and PFS when compared to placebo. Adverse events were common, but manageable and typical of multi-target tyrosine kinase inhibitors. Further research is needed to investigate alternative approaches to the dosing of regorafenib and to explore clinical and molecular biomarkers that can guide patient selection. PMID- 29175678 TI - Systematic review of the clinical and economic value of gene expression profiles for invasive early breast cancer available in Europe. AB - Gene expression profiles with prognostic capacities have shown good performance in multiple clinical trials. However, with multiple assays available and numerous types of validation studies performed, the added value for daily clinical practice is still unclear. In Europe, the MammaPrint, OncotypeDX, PAM50/Prosigna and Endopredict assays are commercially available. In this systematic review, we aim to assess these assays on four important criteria: Assay development and methodology, clinical validation, clinical utility and economic value. We performed a literature search covering PubMed, Embase, Web of Science and Cochrane, for studies related to one or more of the four selected assays. We identified 147 papers for inclusion in this review. MammaPrint and OncotypeDX both have evidence available, including level IA clinical trial results for both assays. Both assays provide prognostic information. Predictive value has only been shown for OncotypeDX. In the clinical utility studies, a higher reduction in chemotherapy was achieved by OncotypeDX, although the number of available studies differ considerably between tests. On average, economic evaluations estimate that genomic testing results in a moderate increase in total costs, but that these costs are acceptable in relation to the expected improved patient outcome. PAM50/prosigna and EndoPredict showed comparable prognostic capacities, but with less economical and clinical utility studies. Furthermore, for these assays no level IA trial data are available yet. In summary, all assays have shown excellent prognostic capacities. The differences in the quantity and quality of evidence are discussed. Future studies shall focus on the selection of appropriate subgroups for testing and long-term outcome of validation trials, in order to determine the place of these assays in daily clinical practice. PMID- 29175680 TI - Inductive reasoning and doubt in obsessive compulsive disorder. AB - BACKGROUND AND OBJECTIVES: Previous studies show that individuals with obsessive compulsive disorder (OCD) accord more importance than healthy controls (HC) to alternative conclusions, resulting in increased doubt regarding an initial conclusion. The goal of the present study was to replicate and extend this finding. METHODS: Eighteen participants diagnosed with OCD and 16 HC completed the Reasoning with Inductive Arguments Task (RIAT), which operationalizes doubt as change in confidence towards a conclusion after alternative conclusions are presented. To examine conditions that facilitate doubt, the impact of alternative conclusions that both supported and contradicted the initial conclusion was compared, as well as the effect of neutral and OCD-relevant item content. RESULTS: Both the OCD and HC groups decreased confidence after contradicting conclusions, but only the HC group increased confidence when presented with supporting conclusions. Furthermore, decrease in confidence in the OCD group correlated with OCD symptom severity. LIMITS: The RIAT could be adapted to better take into account of OCD subtypes. CONCLUSION: Doubt generation may contribute to obsessional doubting. PMID- 29175679 TI - Monitoring microbial communities using light sheet fluorescence microscopy. AB - Microbes often live in dense, dynamic, multi-species communities whose architecture and function are intimately intertwined. Imaging these complex, three-dimensional ensembles presents considerable technical challenges, however. In this review, I describe light sheet fluorescence microscopy, a technique that enables rapid acquisition of three-dimensional images over large fields of view and over long durations, and I highlight recent applications of this method to microbial systems that include artificial closed ecosystems, bacterial biofilms, and gut microbiota. I comment also on the history of light sheet imaging and the many variants of the method. Light sheet techniques have tremendous potential for illuminating the workings of microbial communities, a potential that is just beginning to be realized. PMID- 29175681 TI - In vitro inoculation of Aeromonas hydrophila and Pseudomonas fluorescens in cryopreserved silver barb (Barbodes gonionotus) milt: Effect on fertilization capacity and transmission potential to embryos. AB - Purposive use of cryopreserved sperm contaminated with pathogenic agents has increased the risk of spreading of fish diseases. The objective of this study was to investigate the effects of A. hydrophila subsp. hydrophila and P. fluorescens inoculations into cryostored milt on fertilization capacity and transmission potential to embryos of silver barb (Barbodes gonionotus) with or without 0.25% penicillin-streptomycin (PS) administration. The experiment comprised six treatments: addition of milt into T1) extender only, T2) extender with 0.25% PS, T3) extender with A. hydrophila subsp. hydrophila (BG19), T4) extender with A. hydrophila subsp. hydrophila (BG19) and 0.25% PS, T5) extender with P. fluorescens (BG20) and T6) extender with P. fluorescens (BG20) and 0.25% PS. Milt were loaded into 0.25-mL straws and cryostored in the controlled-rate programmable freezer. After a cryostorage for 28 d, post-thawed sperm were evaluated for the fertilization capacity and risk of pathogen transmission to embryos. Inoculation of A. hydrophila subsp. hydrophila and P. fluorescens into extended milt (T3 and T5) caused a reduction (P < 0.05) in fertilization capacity of cryopreserved sperm. Cryopreserved sperm inoculated with the two pathogenic bacteria and 0.25% PS (T4 and T6) did not fertilize the eggs. The two pathogenic bacteria could be transmitted into embryos after artificial insemination of eggs with bacterial-inoculated cryopreserved sperm, suggesting that the risks of disease transmission via cryopreserved fish sperm would exist. This is the first study reporting pathogenic bacterial transmission on in vitro fish embryos through artificial insemination of cryopreserved sperm. PMID- 29175682 TI - Expression of progesterone receptor protein in the ovine uterus during the estrous cycle: Effects of nutrition, arginine and FSH. AB - To evaluate expression of progesterone receptor (PGR) AB in follicle stimulating hormone (FSH)-treated or non-treated sheep administered with arginine (Arg) or saline (Sal) fed a control (C), excess (O) or restricted (U) diet, uterine tissues were collected at the early, mid and/or late luteal phases. In exp. 1, ewes from each diet were randomly assigned to one of two treatments, Arg or Sal administration three times daily from day 0 of the first estrous cycle until uterine tissue collection. In exp. 2, ewes were injected twice daily with FSH on days 13-15 of the first estrous cycle. Uterine tissues were immunostained to detect PGR followed by image analysis. PGR were detected in luminal epithelium (LE), endometrial glands (EG), endometrial stroma (ES), myometrium (Myo), and endometrial and myometrial blood vessels. The percentage of PR-positive cells and/or intensity of staining were affected by phase of the estrous cycle, plane of nutrition, and/or FSH but not by Arg. In exp. 1, percentage of PGR-positive cells in LE and EG but not in ES and Myo was greater at the early and mid than late luteal phase, was not affected by plane of nutrition, and was similar in LE and EG. Intensity of staining was affected by phase of the estrous cycle and plane of nutrition in LE, EG and Myo, and was the greatest in LE, less in EG, and least in ES and Myo. In exp. 2, percentage of PGR-positive cells in LE, EG, ES and Myo was affected by phase of the estrous cycle, but not by plane of nutrition; was greater at the early than mid luteal phase; and was greatest in LE and EG, less in luminal (superficial) ES and Myo and least in deep ES. Intensity of staining was affected by phase of the estrous cycle and plane of nutrition in all compartments but ES, and was the greatest in LE and luminal EG, less in deep EG, and least in ES and Myo. Comparison of data for FSH (superovulated) and Sal treated (non-superovulated) ewes demonstrated that FSH affected PR expression in all evaluated uterine compartments depending on plane of nutrition and phase of the estrous cycle. Thus, PGR are differentially distributed in uterine compartments, and PGR expression is affected by nutritional plane and FSH, but not Arg depending on phase of the estrous cycle. Such changes in dynamics of PGR expression indicate that diet plays a regulatory role and that FSH-treatment may alter uterine functions. PMID- 29175683 TI - PET microplastics do not negatively affect the survival, development, metabolism and feeding activity of the freshwater invertebrate Gammarus pulex. AB - Over the past decade, microscopic plastic debris, known as microplastics, emerged as a contaminant of concern in marine and freshwater ecosystems. Although regularly detected in aquatic environments, the toxicity of those synthetic particles is not well understood. To address this, we investigated whether the exposure to microplastics adversely affects the amphipod Gammarus pulex, a key freshwater invertebrate. Juvenile (6-9 mm) and adult (12-17 mm) individuals were exposed to irregular, fluorescent polyethylene terephthalate fragments (PET, 10 150 MUm; 0.8-4,000 particles mL-1) for 24 h. Results show that body burden after 24 h depends on the dose and age of G. pulex with juveniles ingesting more microplastics than adults. After chronic exposure over 48 d, microplastics did not significantly affect survival, development (molting), metabolism (glycogen, lipid storage) and feeding activity of G. pulex. This demonstrates that even high concentrations of PET particles did not negatively interfere with the analyzed endpoints. These results contradict previous research on marine crustaceans. Differences may result from variations in the exposure regimes (e.g., duration, particle concentrations), plastic characteristics (e.g., type, size, shape, additives) as well as the species-specific morphological, physiological and behavioral traits. As a detritivorous shredder G. pulex is adapted to feed on non digestible materials and might, therefore, be less sensitive towards exposure to synthetic particles. Accordingly, we argue that the autecology needs to be taken into account and that research should focus on identifying traits that render species susceptible to microplastic exposure. PMID- 29175684 TI - Removal of pharmaceutical compounds in water and wastewater using fungal oxidoreductase enzymes. AB - Due to recalcitrance of some pharmaceutically active compounds (PhACs), conventional wastewater treatment is not able to remove them effectively. Therefore, their occurrence in surface water and potential environmental impact has raised serious global concern. Biological transformation of these contaminants using white-rot fungi (WRF) and their oxidoreductase enzymes has been proposed as a low cost and environmentally friendly solution for water treatment. The removal performance of PhACs by a fungal culture is dependent on several factors, such as fungal species, the secreted enzymes, molecular structure of target compounds, culture medium composition, etc. In recent 20 years, numerous researchers tried to elucidate the removal mechanisms and the effects of important operational parameters such as temperature and pH on the enzymatic treatment of PhACs. This review summarizes and analyzes the studies performed on PhACs removal from spiked pure water and real wastewaters using oxidoreductase enzymes and the data related to degradation efficiencies of the most studied compounds. The review also offers an insight into enzymes immobilization, fungal reactors, mediators, degradation mechanisms and transformation products (TPs) of PhACs. In brief, higher hydrophobicity and having electron-donating groups, such as amine and hydroxyl in molecular structure leads to more effective degradation of PhACs by fungal cultures. For recalcitrant compounds, using redox mediators, such as syringaldehyde increases the degradation efficiency, however they may cause toxicity in the effluent and deactivate the enzyme. Immobilization of enzymes on supports can enhance the performance of enzyme in terms of reusability and stability. However, the immobilization strategy should be carefully selected to reduce the cost and enable regeneration. Still, further studies are needed to elucidate the mechanisms involved in enzymatic degradation and the toxicity levels of TPs and also to optimize the whole treatment strategy to have economical and technical competitiveness. PMID- 29175685 TI - Does maternal environmental tobacco smoke interact with social-demographics and environmental factors on congenital heart defects? AB - Congenital heart defects (CHDs) are a major cause of death in infancy and childhood. Major risk factors for most CHDs, particularly those resulting from the combination of environmental exposures with social determinants and behaviors, are still unknown. This study evaluated the main effect of maternal environmental tobacco smoke (ETS), and its interaction with social-demographics and environmental factors on CHDs in China. A population-based, matched case control study of 9452 live-born infants and stillborn fetuses was conducted using the Guangdong Registry of Congenital Heart Disease data (2004-2014). The CHDs were evaluated by obstetrician, pediatrician, or cardiologist, and confirmed by cardia tomography/catheterization. Controls were randomly chosen from singleton newborns without any malformation, born in the same hospital as the cases and 1:1 matched by infant sex, time of conception, and parental residence (same city and town to ensure sufficient geographical distribution for analyses). Face-to-face interviews were conducted to collect information on demographics, behavior patterns, maternal disease/medication, and environmental exposures. Conditional logistic regression was used to estimate odds ratios and 95% confidence intervals of ETS exposure on CHDs while controlling for all risk factors. Interactive effects were evaluated using a multivariate delta method for maternal demographics, behavior, and environmental exposures on the ETS-CHD relationship. Mothers exposed to ETS during the first trimester of pregnancy were more likely to have infants with CHD than mothers who did not (aOR = 1.44, 95% CI 1.25-1.66). We also observed a significant dose-response relationship when mothers were exposed to ETS and an increasing number of risk factors and CHDs. There were greater than additive interactions for maternal ETS and migrant status, low household income and paternal alcohol consumption on CHDs. Maternal low education also modified the ETS-CHD association on the multiplicative scale. These findings may help to identify high-risk populations for CHD, providing an opportunity for targeted preventive interventions. PMID- 29175686 TI - Nest-defense behaviors in fathead minnows after lifecycle exposure to the antidepressant venlafaxine. AB - Venlafaxine is an antidepressant and anti-anxiety drug that has been detected in municipal wastewater at low MUg/L concentrations. In this study, the nest-defense behavior of adult male fathead minnows (Pimephales promelas) was observed in fish exposed for a full lifecycle to venlafaxine nominal concentrations of 0.88, 8.8, and 88 MUg/L (i.e. 1, 9.3, 75 MUg/L mean measured concentrations). Nest-defense behaviors quantified were the time taken to contact a dummy intruder fish (on a flexible stick, held near each nest) and the number of contacts made during a 1 min period. In male fathead minnows exposed to venlafaxine over a full lifecycle at environmentally relevant nominal concentrations (i.e. 0.88 and 8.8 MUg/L) no significant effects were observed in behavior. However, in males exposed over a full lifecycle to the highest concentration of venlafaxine (i.e. 88 MUg/L), nest defense behaviors were increased in males with empty nests, as shown by the significantly elevated percentage of empty-nest males that made contact with the dummy intruder fish (89%) relative to the lower percentage of contacts (65%) among the Control males (p = 0.046). Lifecycle exposure to high venlafaxine (88 MUg/L) caused males to over-protect their empty nests. Environmental venlafaxine concentrations are approximately 70 x lower than this, so it is unlikely that behavioral changes from venlafaxine exposure would occur in the environment. Normal nest defense behaviours in control males varied, depending on whether they were protecting empty nests or nests with eggs. Compared to Control males with empty nests, more Control males with eggs in their nests made contact with the dummy intruder fish (p = 0.014), contact was faster (i.e. <10 s, p = 0.011), and they hit the dummy intruder fish more times in 1 min (p = 0.031) This study is the first to assess reproductive behaviors in fish exposed to an antidepressant over a full lifecycle. PMID- 29175687 TI - Biouptake, toxicity and biotransformation of triclosan in diatom Cyclotella sp. and the influence of humic acid. AB - Triclosan is one of the most frequently detected emerging contaminants in aquatic environment. In this study, we investigated the biouptake, toxicity and biotransformation of triclosan in freshwater algae Cyclotella sp. The influence of humic acid, as a representative of dissolved organic matter, was also explored. Results from this study showed that triclosan was toxic to Cyclotella sp. with 72 h EC50 of 324.9 MUg L-1. Humic acid significantly reduced the toxicity and accumulation of triclosan in Cyclotella sp. SEM analysis showed that Cyclotella sp. were enormously damaged under 1 mg L-1 triclosan exposure and repaired after the addition of 20 mg L-1 humic acid. Triclosan can be significantly taken up by Cyclotella sp. The toxicity of triclosan is related to bioaccumulated triclosan as the algal cell numbers decreased when intracellular triclosan increased. A total of 11 metabolites were identified in diatom cells and degradation pathways are proposed. Hydroxylation, methylation, dechlorination, amino acids conjunction and glucuronidation contributed to the transformative reactions of triclosan in Cyclotella sp., producing biologically active products (e.g., methyl triclosan) and conjugation products (e.g., glucuronide or oxaloacetic acid conjugated triclosan), which may be included in the detoxification mechanism of triclosan. PMID- 29175688 TI - Language-specific skills in intercultural healthcare communication: Comparing perceived preparedness and skills in nurses' first and second languages. AB - BACKGROUND: Interactions between people from different cultures are becoming increasingly commonplace in contemporary healthcare settings. To date, most research evaluating cross-cultural preparedness has assumed that medical professionals are speaking their first language (L1). However, as healthcare workers are increasingly mobile and patient populations are increasingly diverse, more and more interactions are likely to occur in a professional's non-native language (L2). OBJECTIVES: This study assessed and compared nurses' perceived cross-cultural preparedness and skillfulness in their interactions with patients from other cultures when speaking both their L1 and L2. The goal of this project was to inform the creation of a communication skills training program. DESIGN: Nurses reported their perceived cross-cultural preparedness and skillfulness (scales adapted from Park et al., 2009) in their L1 and L2 via an online questionnaire. SETTINGS: This questionnaire was distributed among nurses working in Vienna, Austria, through the Vienna Hospital Association (VHA). PARTICIPANTS: Nurses and nurses-in-training working in VHA hospitals participated. Most participants who provided demographic information were currently nurses (n=179) with an average of 16.88years (SD=11.50) of professional experience (range: 0 40); n=40 were nurses-in-training with an average of 2.13years (SD=0.88) of experience (range: 1-5). METHODS: Descriptive statistics for each cross-cultural preparedness and skillfulness (in each language) are reported; comparisons between L1 and L2 responses were also conducted. Multiple regression analyses were used to identify predictors of preparedness and L1/L2 skillfulness. RESULTS: Nurses reported feeling significantly less confident in their skills when working in an L2, across a range of culture-related issues. Having had previous communication skills training predicted (better) self-reported L2 skillfulness, although it did not predict L1 skillfulness. CONCLUSIONS: These results indicate that there is a language-specific component to cross-cultural skillfulness. Thus, there is a need for language-specific skills training to address L2 skill deficits. PMID- 29175689 TI - Reflective seminaries grounded in caring science and lifeworld theory - A phenomenological study from the perspective of nursing students. PMID- 29175690 TI - Human trafficking education for nurse practitioners: Integration into standard curriculum. AB - BACKGROUND: Human trafficking is a crime resulting in serious negative health outcomes for the victims. To provide optimal care, thus improving health outcomes, healthcare providers must be able to identify victims as they seek care for acute and chronic physical illness, communicable diseases, sexually transmitted infections, and mental health disorders (Lederer and Wetzel, 2014; Oram et al., 2012). Unfortunately, healthcare providers lack appropriate knowledge of clues that would lead to victim identification. This may result in a failure to identify victims (Beck et al., 2015; Ross et al., 2015; Konstantopoulos et al., 2013; Chisolm-Straker et al., 2012). Increasing the number of healthcare providers able to identify, treat, and refer victims of trafficking for further care is imperative. OBJECTIVES: The study evaluated the knowledge level of student nurse practitioners enrolled in an adult, family, or pediatric clinical course. Knowledge domains included the definitions, laws, prevalence, identification, treatment, and community and social service resources. DESIGN/SETTING/PARTICIPANTS: The study was designed as a non probability sampling of adult, family, and pediatric nurse practitioner students (n=73). Participants included students enrolled in the Adult & Older Adult I or the Primary Care of the Child & Adolescent I course at a large public university. METHODS: The study was designed as a one hour educational intervention intended for presentation in a lecture-style format. The educational intervention included a PowerPoint lecture and embedded videos. The pre-survey, designed as a paper survey, contained a demographic section followed by six survey questions covering the six domains of interest. Following the intervention, participants completed the post-survey prior to leaving the classroom. RESULTS: Pre-survey results pinpointed knowledge gaps across all six domains under investigation. Post-survey results revealed an increase in knowledge across all six domains of interest. CONCLUSIONS: The educational intervention increased knowledge of human trafficking among students enrolled in a nurse practitioner program. Informed nurse practitioners have the ability to identify, treat, and refer victims of trafficking. As an integral part of the health care team, nurse practitioners should receive trafficking education as part of the standard course curricula. PMID- 29175691 TI - A theory of planned behaviour perspective on practitioners' beliefs toward the integration of the WIXX communication campaign messages and activities into daily practice. AB - OBJECTIVES: To favour the dissemination and the implementation of the WIXX multimedia communication campaign, the aim of this study was to examine practitioners' beliefs towards the integration of the WIXX campaign activities into daily practice. STUDY DESIGN: An exploratory qualitative study. METHODS: Overall, 58 community-based practitioners completed an online questionnaire based on the theory of planned behaviour guidelines pertaining to perceived advantages/disadvantages and perceived barriers/facilitators toward the campaign. A content analysis was performed by two independent coders to extract modal beliefs. Results were validated by a third coder. RESULTS: Local partners had a positive attitude toward the WIXX campaign, but significant barriers remained and needed to be addressed to ensure full implementation of this campaign (e.g. lack of time or resources, additional workload, complexity of the registration process and so forth). Beliefs were fragmented and diversified, indicating that they were highly context dependent. CONCLUSIONS: To conclude, some remaining challenges regarding the full implementation of the WIXX communication campaign were identified, suggesting that additional efforts might be needed to ensure the full adoption of the campaign by local practitioners. PMID- 29175692 TI - Interpreting microbiologically assisted cracking with Ee-pH diagrams. AB - Although many mechanisms have been proposed to explain the microbiologically assisted cracking (MAC) of steel and copper, a theoretical interpretation is necessary. In this paper, we attempt to give a theoretical interpretation of sulfate/nitrate reducing bacteria (SRB/NRB)-assisted cracking using Ee-pH diagrams. Under the combined actions of SRB/NRB and external stress, the cell potential (Ecell) and the corrosion current density of the corrosion reaction increase, such that the corrosion reactions become more thermodynamically favorable. This is the nature of MAC. Nitrate is a far more potent oxidant than sulfate, and thus, the NRB-assisted cracking of iron is a more thermodynamically favorable process than the SRB-assisted cracking. Furthermore, the thermodynamic interpretation is attempted to implicate into the classical stress corrosion cracking mechanisms of pipeline steel. PMID- 29175693 TI - Influence of valproate on language functions in children with epilepsy. AB - The aim of the current study was to assess the influences of valproate (VPA) on the language functions in newly diagnosed pediatric patients with epilepsy. We reviewed medical records of 53 newly diagnosed patients with epilepsy, who were being treated with VPA monotherapy (n=53; 22 male patients and 31 female patients). The subjects underwent standardized language tests, at least twice, before and after the initiation of VPA. The standardized language tests used were The Test of Language Problem Solving Abilities, a Korean version of The Expressive/Receptive Language Function Test, and the Urimal Test of Articulation and Phonology. Since all the patients analyzed spoke Korean as their first language, we used Korean language tests to reduce the bias within the data. All the language parameters of the Test of Language Problem Solving Abilities slightly improved after the initiation of VPA in the 53 pediatric patients with epilepsy (mean age: 11.6+/-3.2years), but only "prediction" was statistically significant (determining cause, 14.9+/-5.1 to 15.5+/-4.3; making inference, 16.1+/-5.8 to 16.9+/-5.6; prediction, 11.1+/-4.9 to 11.9+/-4.2; total score of TOPS, 42.0+/-14.4 to 44.2+/-12.5). The patients treated with VPA also exhibited a small extension in mean length of utterance in words (MLU-w) when responding, but this was not statistically significant (determining cause, 5.4+/-2.0 to 5.7+/ 1.6; making inference, 5.8+/-2.2 to 6.0+/-1.8; prediction, 5.9+/-2.5 to 5.9+/ 2.1; total, 5.7+/-2.1 to 5.9+/-1.7). The administration of VPA led to a slight, but not statistically significant, improvement in the receptive language function (range: 144.7+/-41.1 to 148.2+/-39.7). Finally, there were no statistically significant changes in the percentage of articulation performance after taking VPA. Therefore, our data suggested that VPA did not have negative impact on the language function, but rather slightly improved problem-solving abilities.

AB - Our goal was to evaluate how accurate neurologists are at differentiating between different paroxysmal events based on clinical history versus observation of the spell in question. Forty-seven neurologists reviewed 12 clinical histories and videos of recorded events of patients admitted in the Epilepsy Monitoring Unit (EMU). They were asked to diagnose events as epileptic seizures, non-epileptic behavioral spells (NEBS), or other physiologic events as well as rate their confidence in their diagnosis. The median diagnostic accuracy for all paroxysmal events was 67% for clinical history and 75% for observation (p=.001). This was largely due to the difference in accuracy within the subgroup of patients with NEBS (67% history vs. 83% observation, p<.001). There were trends for higher diagnostic accuracy and increased inter-rater agreement with higher levels of training. Physicians with higher levels of training were more confident with diagnosis based on observation. In summary, reviewing videos of paroxysmal spells may improve diagnostic accuracy and enhance the evaluation of patients. Neurologists at all levels of training should encourage the recording and review of videos of recurrent spells to aid in medical decision-making especially when there is high concern that the spells in question are NEBS. PMID- 29175695 TI - Determination of non-liposomal and liposomal doxorubicin in plasma by LC-MS/MS coupled with an effective solid phase extraction: In comparison with ultrafiltration technique and application to a pharmacokinetic study. AB - Liposomal formulation of doxorubicin has been widely applied in clinic for treatment of various cancers. The separation and measurement of free drug (drug which is not entrapped in liposomes) and liposomal drug in the plasma after injection of liposomal doxorubicin is of prime importance due to toxicity and activity concerns. In this study, a rapid and convenient method was developed to isolate and determine the non-liposomal and liposomal drugs in plasma. Plasma samples were prepared by solid phase extraction (SPE) using Oasis HLB cartridges. Liposomal doxorubicin (L-DOX) was collected in the aqueous eluate with its internal standard (IS), metformin; and non-liposomal doxorubicin (NL-DOX) and its isotope labelling IS were eluted from the cartridge by methanol containing 0.5% formic acid. After SPE separation, L-DOX and NL-DOX were subsequently quantified by a validated sensitive LC-MS/MS method individually. The calibration curves were found to be linear for L-DOX in the range of 0.156-40.0MUg/mL and for NL-DOX in the range of 3.13-200ng/mL. The extraction recovery was about 97% for L-DOX and about 65% for NL-DOX. This method was further applied to investigate the pharmacokinetics of doxorubicin in Beagle dogs after an intravenous dose of 1.0mg/kg Doxil(r). After injection of Doxil(r), L-DOX was the predominant component circulating in plasma, whose amount was about 1000-fold higher than that of NL-DOX. The analytical method might be helpful in pharmacokinetics and toxicity assessment of liposomal formulation. PMID- 29175696 TI - Determination of adrenaline, noradrenaline and corticosterone in rodent blood by ion pair reversed phase UHPLC-MS/MS. AB - A novel ion pair reversed phase ultra high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method for simultaneous determination of the stress hormones adrenaline, noradrenaline and corticosterone in rodent blood was developed and fully validated. Separations were performed on an Acquity HSS T3 column (2.1mm i.d.*100mm, 1.8MUm) with gradient elution and a runtime of 5.5min. The retention of adrenaline and noradrenaline was substantially increased by employing the ion pair reagent heptafluorobutyric acid (HFBA). Ion pair reagents are usually added to the mobile phase only, but we demonstrate for the first time that including HFBA to the sample reconstitution solvent as well, has a major impact on the chromatography of these compounds. The stability of adrenaline and corticosterone in rodent blood was investigated using the surrogate analytes adrenaline-d3 and corticosterone-d8. The applicability of the described method was demonstrated by measuring the concentration of stress hormones in rodent blood samples. PMID- 29175697 TI - In vivo study of erysolin metabolic profile by ultra high performance liquid chromatography coupleded to Fourier transform ion cyclotron resonance mass spectrometry. AB - An ultra high performance liquid chromatography coupled to Fourier transform ion cyclotron resonance mass spectrometry (UHPLC-FT-ICR-MS) method was developed for the first time to study the in vivo metabolism of erysolin, a compound derived from cruciferous plants which has a definite effect of anti-tumor and anti-nerve injury. In this research, the chromatographic separation was performed on an ACQUITY UPLC(r) BEH C18 column (2.1 mm*100mm, 1.7MUm, Waters, USA) and eluted by a gradient program, the identification work was achieved on a Bruker ultra-high resolution spectrometer in positive ion mode. Plasma, urine, feces and bile samples were collected from rats to screen metabolites after an intragastric administration of erysolin at the dose of 100mg/kg. As a result, the parent drug and a total of six phase II metabolites were detected and preliminarily identified by analyzing their MS and MS/MS spectrometry profiles. Our results indicated that erysolin mainly metabolized via the mercapturic acid metabolic pathway, erysolin first react with glutathione to form glutathione conjugate, followed by taking off the glutamic acid and glycine to form cysteine conjugate, then the N-acetylation reaction occurs, the product would be excreted out of the body at last. In conclusion, results obtained in our study may contribute to a better understanding of the metabolism process and characteristics of erysolin in vivo, and provide an important reference for future research. PMID- 29175698 TI - Lipophilicity assessement in drug discovery: Experimental and theoretical methods applied to xanthone derivatives. AB - For the last several years, searching of new xanthone derivatives (XDs) with potential pharmacological activities has remained one of the main areas of interest of our group. The optimization of biological activity and drug-like properties of hits and leads is crucial at early stage of the drug discovery pipeline. Lipophilicity is one of the most important drug-like properties having a great impact in both pharmacokinetics and pharmacodynamics processes. In this work, we describe the lipophilicity of a small library of bioactive XDs, previously synthesized by our group, using different methods: computational, vortex-assisted liquid-liquid microextraction coupled with high-performance liquid chromatography (VALLME-HPLC), reversed-phase high-performance thin layer chromatography (RP-HPTLC), reversed-phase high-performance liquid chromatography (RP-HPLC), and biomembrane model by the partition between micelles and aqueous phase. The different results obtained by the used methods were compared and discussed. The methodologies and data gathered in this study will expand the investigation of lipophilicity of XDs, an important class of compounds in medicinal chemistry. PMID- 29175699 TI - "Do-it-yourself": Vaccine rejection and complementary and alternative medicine (CAM). AB - In this article, we elucidate a symbiotic relationship between complementary and alternative medicine (CAM) and rejection of, or hesitancy towards, vaccination. In Fremantle, Western Australia, and Adelaide, South Australia, we conducted in depth interviews from September 2013-December 2015 with 29 parents who had refused or delayed some or all of their children's vaccines. Our qualitative analysis found that for many, their do-it-yourself ethic and personal agency was enhanced by self-directed CAM use, alongside (sometimes informal) CAM practitioner instruction. Reifying 'the natural,' these parents eschewed vaccines as toxic and adulterating, and embraced CAM as a protective strategy for immune systems before, during and after illness. Users saw CAM as harm-free, and when it came to experiences that non-users might interpret as demonstrating CAM's ineffectiveness, they rationalised to the contrary. They also generally glossed over its profit motive. CAM emerged as part of an expert system countering Western medicine. CAM's faces were trusted and familiar, and its cottage capitalism appeared largely free from the taint of "Big Pharma." A few parents employed a scientific critique of CAM modalities - and a minority were dubious of its profit motive - but others rejected the epistemology underpinning biomedicine, framing CAM as a knowledge not poisoned by avarice; a wisdom whose very evidence-base (anecdote and history) was demeaned by an arrogant scientific process only permitting belief in that which could be quantified. However, all parents engaged with Western medicine for broken bones and, sometimes, medical diagnoses. Our analysis suggests that pro-vaccination health professionals, policymakers and information-providers seeking to address the role of CAM in vaccine rejection face significant challenges due to the epistemic basis of some parents' decisions. However, we make some suggestions for professional practice and policy to enhance trust in vaccination. PMID- 29175700 TI - Social capital, income inequality and the social gradient in self-rated health in Latin America: A fixed effects analysis. AB - Latin America is the most unequal region in the world. The current sustainable development agenda increased attention to health inequity and its determinants in the region. Our aim is to investigate the social gradient in health in Latin America and assess the effects of social capital and income inequality on it. We used cross-sectional data from the World Values Survey and the World Bank. Our sample included 10,426 respondents in eight Latin American countries. Self-rated health was used as the outcome. Education level was the socioeconomic position indicator. We measured social capital by associational membership, civic participation, generalized trust, and neighborhood trust indicators at both individual and country levels. Income inequality was operationalized using the Gini index at country-level. We employed fixed effects logistic regressions and cross-level interactions to assess the impact of social capital and income inequality on the heath gradient, controlling for country heterogeneity. Education level was independently associated with self-rated health, representing a clear social gradient in health, favoring individuals in higher socioeconomic positions. Generalized and neighborhood trust at country-level moderated the effect on the association between socioeconomic position and health, yet favoring individuals in lower socioeconomic positions, especially in lower inequality countries, despite their lower individual social capital. Our findings suggest that collective rather than individual social capital can impact the social gradient in health in Latin America, explaining health inequalities. PMID- 29175701 TI - From therapeutic landscapes to healthy spaces, places and practices: A scoping review. AB - The term 'therapeutic landscapes' was first coined by health geographer, Wilbert Gesler, in 1992 to explore why certain environments seem to contribute to a healing sense of place. Since then, the concept and its applications have evolved and expanded as researchers have examined the dynamic material, affective and socio-cultural roots and routes to experiences of health and wellbeing in specific places. Drawing on a scoping review of studies of these wider therapeutic landscapes published between 2007 and 2016, this paper explores how, where, and to what benefit the 'therapeutic landscapes' concept has been applied to date, and how such applications have contributed to its critical evolution as a relevant and useful concept in health geography. Building on themes included in two earlier (1999, 2007) edited volumes on Therapeutic Landscapes, we summarise the key themes identified in the review, broadly in keeping with the core material, social, spiritual and symbolic dimensions of the concept initially posited by Gesler. Through this process, we identify strengths and limitations of the concept and its applications, as well as knowledge gaps and promising future directions for work in this field, reflecting critically on its value within health geography and its potential contribution to wider interdisciplinary discussions and debates around 'healthy' spaces, places, and related practices. PMID- 29175702 TI - Government health insurance and spatial peer effects: New evidence from India. AB - What is the role of spatial peers in diffusion of information about health care? We use the implementation of a health insurance program in Karnataka, India that provided free tertiary care to poor households to explore this issue. We use administrative data on location of patient, condition for which the patient was hospitalized and date of hospitalization (10,507 observations) from this program starting November 2009 to June 2011 for 19 months to analyze spatial and temporal clustering of tertiary care. We find that the use of healthcare today is associated with an increase in healthcare use in the same local area (group of villages) in future time periods and this association persists even after we control for (1) local area fixed effects to account for time invariant factors related to disease prevalence and (2) local area specific time fixed effects to control for differential trends in health and insurance related outreach activities. In particular, we find that 1 new hospitalization today results in 0.35 additional future hospitalizations for the same condition in the same local area. We also document that these effects are stronger in densely populated areas and become pronounced as the insurance program becomes more mature suggesting that word of mouth diffusion of information might be an explanation for our findings. We conclude by discussing implications of our results for healthcare policy in developing economies. PMID- 29175703 TI - Omics-based natural product discovery and the lexicon of genome mining. AB - Genome sequencing and the application of omic techniques are driving many important advances in the field of microbial natural products research. Despite these gains, there remain aspects of the natural product discovery pipeline where our knowledge remains poor. These include the extent to which biosynthetic gene clusters are transcriptionally active in native microbes, the temporal dynamics of transcription, translation, and natural product assembly, as well as the relationships between small molecule production and detection. Here we touch on a number of these concepts in the context of continuing efforts to unlock the natural product potential revealed in genome sequence data and discuss nomenclatural issues that warrant consideration as the field moves forward. PMID- 29175704 TI - Synthesis and mechanistic investigation of iron(II) complexes of isoniazid and derivatives as a redox-mediated activation strategy for anti-tuberculosis therapy. AB - The emergence of multidrug-resistant strains of Mycobacterium tuberculosis (MTB) represents a major threat to global health. Isoniazid (INH) is a prodrug used in the first-line treatment of tuberculosis. It undergoes oxidation by a catalase peroxidase KatG, leading to generation of an isonicotinoyl radical that reacts with NAD(H) forming the INH-NADH adduct as the active metabolite. A redox mediated activation of isoniazid using an iron metal complex was previously proposed as a strategy to overcome isoniazid resistance due to KatG mutations. Here, we have prepared a series of iron metal complexes with isoniazid and analogues, containing alkyl substituents at the hydrazide moiety, and also with pyrazinamide derivatives. These complexes were activated by H2O2 and studied by ESR and LC-MS. For the first time, the formation of the oxidized INH-NAD adduct from the pentacyano(isoniazid)ferrate(II) complex was detected by LC-MS, supporting a redox-mediated activation, for which a mechanistic proposition is reported. ESR data showed all alkylated hydrazides, in contrast to non substituted hydrazides, only generated alkyl-based radicals. The structural modifications did not improve minimal inhibitory concentration (MIC) against MTB in comparison to isoniazid iron complex, providing support to isonicotinoyl radical formation as a requirement for activity. Nonetheless, the pyrazinoic acid hydrazide iron complex showed redox-mediated activation using H2O2 with generation of a pyrazinoyl radical intermediate and production of pyrazinoic acid, which is in fact the active metabolite of pyrazinamide prodrug. Thereby, this strategy can also unveil new opportunities for activation of this type of drug. PMID- 29175706 TI - Implicit memory of locations and identities: A developmental study. AB - Objects in the environment have both location and identity properties. However, it is unclear how these independent properties are processed and combined in the implicit domain. The current study investigated the development of the implicit memory of object locations and object identities, both independently and combined, and the relation between implicit memory and working memory (WM) for these properties. Three age groups participated: 6- and 7-year-old children, 9- and 10-year-old children, and adults. Children and adults completed a repeated search paradigm. In the learning phase, targets' locations were consistently predicted by both the identities and locations of the distracters. In the test phase, either both remained predictive or just the identities or just the locations of the distracters predicted the location of the target. All groups showed significant implicit learning when both the identities and locations of the distracters remained predictive. When only the locations but not the identities of the distracters were predictive, adults and 9- and 10-year-olds showed significant learning, whereas 6- and 7-year-olds did not. When only the identities but not the locations of the distracters were predictive, none of the groups showed significant learning effects. In evaluating the contributions of either visual or spatial WM to implicit learning and memory, we found that children with smaller visual WM exhibited larger implicit memory effects for object identities than did children with larger visual WM. Taken together, the results indicate that children's ability to differentiate identity and location undergoes development even in the implicit domain. PMID- 29175707 TI - Using the glycan toolbox for pathogenic interventions and glycan immunotherapy. AB - Glycans play a crucial role to discern between self and foreign entities by providing key recognition elements for C-type lectin receptors (CLRs) and Siglec receptors expressed on immune cells. The glycan recognition of CLRs has illustrated a potent immune modulatory role affecting not only innate pathogen binding and immune signalling, but also Thelper differentiation, cytokine production and antigen presentation. This broad range of influence has implicated glycans in the pathogenesis of infectious diseases but also revealed their extraordinary properties in cancer. Glycan binding by CLRs and Siglecs can be exploited for immunotherapy and the design of glycan-based therapeutics and their multivalent requirements will aspire new biotechnological approaches to effectively interfere in immunological processes in cancer and infectious diseases. PMID- 29175705 TI - Quantifying attentional effects on the fidelity and biases of visual working memory in young children. AB - Attentional control enables us to direct our limited resources to accomplish goals. The ability to flexibly allocate resources helps to prioritize information and inhibit irrelevant/distracting information. We examined developmental changes in visual working memory (VWM) fidelity in 4- to 7-year-old children and the effects that a distracting non-target object can exert in biasing their memory representations. First, we showed that VWM fidelity improves from early childhood to adulthood. Second, we found evidence of working memory load on recall variability in children and adults. Next, using cues to manipulate attention, we found that older children are able to construct a more durable memory representation for an object presented following a non-target using a pre-cue (that biases encoding before presentation) compared with a retro-cue (that signals which item to recall after presentation). In addition, younger children had greater difficulties maintaining an item in memory when an intervening item was presented. Lastly, we found that memory representations are biased toward a non-target when it is presented following the target and away from a non-target when it precedes the target. These bias effects were more pronounced in children compared with adults. Together, these results demonstrate changes in attention over development that influence VWM memory fidelity. PMID- 29175708 TI - Engineering of biomolecules by bacteriophage directed evolution. AB - Conventional in vivo directed evolution methods have primarily linked the biomolecule's activity to bacterial cell growth. Recent developments instead rely on the conditional growth of bacteriophages (phages), viruses that infect and replicate within bacteria. Here we review recent phage-based selection systems for in vivo directed evolution. These approaches have been applied to evolve a wide range of proteins including transcription factors, polymerases, proteases, DNA-binding proteins, and protein-protein interactions. Advances in this field expand the possible applications of protein and RNA engineering. This will ultimately result in new biomolecules with tailor-made properties, as well as giving us a better understanding of basic evolutionary processes. PMID- 29175709 TI - Alpha7 nicotinic acetylcholine receptor-specific agonist DMXBA (GTS-21) attenuates Abeta accumulation through suppression of neuronal gamma-secretase activity and promotion of microglial amyloid-beta phagocytosis and ameliorates cognitive impairment in a mouse model of Alzheimer's disease. AB - We previously demonstrated that stimulation of nicotinic acetylcholine receptors (nAChRs) increases amyloid-beta (Abeta) phagocytosis in rat microglia and is closely associated with the decrease of brain Abeta and amelioration of memory dysfunction in a transgenic mouse model of Alzheimer's disease (AD). Here, we examined the subtypes of nAChRs involved in these beneficial effects. In primary cultures of rat microglia, the alpha7 nAChR selective agonist 3-[(2,4 dimethoxy)benzylidene]-anabaseine dihydrochloride (DMXBA) promoted Abeta and fluorescent latex bead phagocytosis, whereas selective alpha7 nAChR antagonists suppressed the enhanced Abeta phagocytosis. In a transgenic mouse model of AD, administration of DMXBA attenuated brain Abeta burden and memory dysfunction. Moreover, DMXBA suppressed gamma-secretase activity in solubilized fractions of human neuroblastoma cells and transgenic mouse brain. These results suggested that selective activation of alpha7 nAChRs promoted microglial Abeta phagocytosis and suppressed neuronal gamma-secretase activity to contribute to the attenuation of the brain Abeta burden and cognitive impairment. Thus, we propose neuronal and microglial alpha7 nAChRs as new therapeutic targets in the treatment of AD. PMID- 29175710 TI - EEG correlates of visual short-term memory in older age vary with adult lifespan cognitive development. AB - Visual short-term memory (vSTM) is a cognitive resource that declines with age. This study investigated whether electroencephalography (EEG) correlates of vSTM vary with cognitive development over individuals' lifespan. We measured vSTM performance and EEG in a lateralized whole-report task in a healthy birth cohort, whose cognitive function (intelligence quotient) was assessed in youth and late middle age. Higher vSTM capacity (K; measured by Bundesen's theory of visual attention) was associated with higher amplitudes of the contralateral delay activity (CDA) and the central positivity (CP). In addition, rightward hemifield asymmetry of vSTM (Klambda) was associated with lower CDA amplitudes. Furthermore, more severe cognitive decline from young adulthood to late-middle age predicted higher CDA amplitudes, and the relationship between K and the CDA was less reliable in individuals who show higher levels of cognitive decline compared to individuals with preserved abilities. By contrast, there was no significant effect of lifespan cognitive changes on the CP or the relationship between behavioral measures of vSTM and the CP. Neither the CDA, nor the CP, nor the relationships between K or Klambda and the event-related potentials were predicted by individuals' current cognitive status. Together, our findings indicate complex age-related changes in processes underlying behavioral and EEG measures of vSTM and suggest that the K-CDA relationship might be a marker of cognitive lifespan trajectories. PMID- 29175711 TI - Evidence for estrogeno-mimetic effects of a mixture of low-dose pollutants in a model of ovariectomized mice. AB - We recently hypothesized that a mixture of low-dosed dioxin, polychlorobiphenyl, phthalate and bisphenol may induce estrogeno-mimetic activities in a model of lifelong-exposed female mice. Herein, we evaluated the impact of this mixture in estrogen deficiency conditions. Based on the protective effects of estrogens against metabolic disorders, we reasoned that exposure to pollutants should attenuate the deleterious metabolic effects induced by ovariectomy. In line with the hypothesis, exposure to pollutants was found to reduce the impact of ovariectomy on glucose intolerance and insulin resistance, to enhance the expression levels of the hepatic estrogen receptor alpha and to attenuate the ovariectomy-induced enhancement of the chemokine MCP-1/CCL2 considered as an indicator of estrogen signalling. Because of the very low doses of pollutants used in mixture, these findings may have strong implications in terms of understanding the potential role of environmental contaminants in the development of metabolic diseases, specifically in females during menopausal transition.

AB - Herein, we report a new simple and biological approach for the preparation of capsaicin adsorbed reduced graphene oxide (RGO), where capsaicin acts as a stabilizing and deoxygenating agent. The capsaicin that is decorated on graphene surface plays an important role as a capping agent to avoid the aggregation of graphene sheets. The capsaicin functionalized RGO stimulated the differentiation and proliferation of osteoblasts to a larger extent, which is a significant feature for the use of biomaterials in biomedical application such as in bone tissue engineering, more speciafically in the case of diseases such as osteoporosis. PMID- 29175713 TI - Lateral habenula in the pathophysiology of depression. AB - Depression is a devastating disorder with a combination of diverse symptoms such as low self-esteem, lack of motivation, anhedonia, loss of appetite, low energy, and discomfort without a clear cause. Depression has been suggested to be the result of maladaptive changes in specific brain circuits. Recently, the lateral habenula (LHb) has emerged as a key brain region in the pathophysiology of depression. Increasing evidence from rodent, non-human primate and human studies indicates that the aberrant activity of the LHb is associated with depressive symptoms such as helplessness, anhedonia, and excessive negative focus. Revealing the molecular, cellular and circuit properties of the LHb will help explain how abnormalities in LHb activity are linked to depressive disorders, and shed light on developing novel strategies for depression treatment. PMID- 29175714 TI - The effect of additional activation of the plantar intrinsic foot muscles on foot dynamics during gait. AB - BACKGROUND: The plantar intrinsic foot muscles (PIFMs) contribute to support the medial longitudinal arch. But the functional role of the PIFMs during dynamic activities is not clear. The purpose of this study was to examine the change in the foot dynamics during gait accompanied with the change in the PIFMs activity to determine the functional role of the PIFMs during gait. METHODS: Twenty healthy male subjects were randomly assigned to the electrical stimulation group (ESG) or control group (CG). In the ESG, the electrical stimulation to the PIFMs was provided from mid-stance to pre-swing using surface electrodes to simulate reinforcement of the PIFMs. The foot dynamics during the stance phase of gait was measured using a 3D motion analysis, and the amount of change from baseline (electrical stimulation was not provided) was compared between groups using an independent sample t-test. RESULTS: In the ESG, the timing for the navicular height to reach the minimum value was significantly later, and the vertical ground reaction force (2nd peak) significantly decreased more. There were no group differences in the amount of change from baseline on gait velocity, stance phase duration, minimum navicular height and ground reaction force in other directions. CONCLUSION: Results from this study showed that the functions of the PIFMs most likely include shock absorption and facilitation of efficient foot ground force transmission during the stance phase of gait. PMID- 29175715 TI - Manual therapy for plantar heel pain. AB - BACKGROUND: Manual therapy employed in the treatment of plantar heel pain includes joint or soft tissue mobilizations. Efficacy of these methods is still under debate. AIMS: To determine whether manual therapy, consisting of deep massage, myofascial release or joint mobilization is effective in treating plantar heel pain. METHODS: A critical review of all available studies with an emphasis on randomized controlled trials (RCTs) was performed. PubMed, PEDro, and Google Scholar databases were searched for keywords relating to plantar heel pain, joint, and soft tissue mobilizations. There were no search limitations or language restrictions. The reference lists of all retrieved articles were searched. The PEDro score was used to assess the quality of the reviewed papers. RESULTS: A total of six relevant RCTs were found: two examined the effectiveness of joint mobilization on plantar heel pain and four the effectiveness of soft tissue techniques. Five studies showed a positive short-term effect after manual therapy treatment, mostly soft tissue mobilizations, with or without stretching exercises for patients with plantar heel pain, compared to other treatments. One study observed that adding joint mobilization to the treatment of plantar heel pain was not effective. The quality of all studies was moderate to high. CONCLUSIONS: According to reviewed moderate and high-quality RCTs, soft tissue mobilization is an effective modality for treating plantar heel pain. Outcomes of joint mobilizations are controversial. Further studies are needed to evaluate the short and long-term effect of different soft tissue mobilization techniques. PMID- 29175716 TI - Diabetes foot screening: Current practice and the future. PMID- 29175717 TI - Tibio-calcaneal fusion by retrograde intramedullary nailing in charcot neuroarthropathy. AB - INTRODUCTION: Charcot's neuroarthropathy of ankle leads to instability, destruction of the joint with significant morbidity that may require an amputation. Aim of surgical treatment is to achieve painless stable plantigrade foot through arthrodesis. Achieving surgical arthrodesis in Charcot's neuroarthropathy has a high failure rate. We assess the outcomes of retrograde intramedullary interlocked nailing in tibio-talar arthrodesis for Charcot's neuroarthropathy. MATERIALS AND METHODS: 42 diabetic patients with a mean age of 49 year underwent ankle tibio-talar arthrodesis using retrograde nailing for Charcot's neuroarthropathy. The postoperative complications have been discussed and their management outlined. The outcomes were measured radiologically and clinically. Follow up was done after 6 weeks, 3 months, 6 months and 1 year. RESULTS: 14 patients (33.3%) achieved uneventful uncomplicated fusion. Thirty three patients had varus deformity. Nine patients had valgus deformity. Using Paired t test, it showed statistically significant improvement in the functional outcomes (AOFAS& EQ-5D-5L) over the follow up time, despite of the mild deterioration of radiological angles in the final follow up visit compared to the postoperative radiological findings. CONCLUSION: Retrograde nailing is one of the best options for tibio-talo-calcaneal arthrodesis in the high-risk Charcot's neuroarthropathy population. It could be done through small incisions with lower soft tissue complications, its load-sharing properties allows a considerable compression across the ankle and talocalcaneal joints with early weight bearing and with satisfactory functional outcomes. PMID- 29175718 TI - Does sound structure affect word learning? An eye-tracking study of Danish learning toddlers. AB - Previous research has shown that Danish-learning children lag behind in early lexical acquisition compared with children learning a number of other languages. This delay has been ascribed to the opaque phonetic structure of Danish, which appears to have fewer reliable segmentation cues than other closely related languages. In support of this hypothesis, recent work has shown that the phonetic properties of Danish negatively affect online language processing in young Danish children. In this study, we used eye-tracking to investigate whether the challenges associated with processing Danish also affect how Danish-learning children between 24 and 35 months of age establish and learn novel label-object mappings. The children were presented with a series of novel mappings, either ostensively (one novel object presented alone on the screen) or ambiguously (one novel object presented together with a familiar one), through carrier phrases with different phonetic structures (more vs less opaque). Our results showed two main trends. First, Danish-learning children performed poorly on the task of mapping novel labels onto novel objects. Second, when learning did occur, accuracy was affected by the phonetic opacity of the speech stimuli. We suggest that this finding results from the interplay of a perceptually challenging speech input and a slower onset of early vocabulary experience, which in turn may delay the onset of word learning skills in Danish-learning children. PMID- 29175719 TI - Does chronic ankle instability influence lower extremity muscle activation of females during landing? AB - Much remains unclear about how chronic ankle instability (CAI) could affect knee muscle activations and interact with knee biomechanics. Therefore, the purpose of this study was to assess the influence of CAI on the lower extremity muscle activation at the ankle and knee joints during landings on a tilted surface. A surface electromyography system and two force plates were used to collect lower extremity muscle activation of 21 young female individuals with CAI and 21 pair matched controls during a double-leg landing with test limb landing on the tilted surface. In the pre-landing phase, compared to controls, CAI participants displayed a reduced ankle evertor activation that could place CAI at a high risk of giving way or sprain injury. In the landing phase, an increased tibialis anterior activation of CAI led to increased co-contraction of ankle muscles in the sagittal and frontal plane. A greater ankle muscle co-contraction could increase the ankle stability during landings but may adversely influence the knee muscle activations (e.g., a greater co-contraction ratio of quadriceps to hamstrings). Relevant training programs (e.g., increasing pre-landing peroneal activation, and optimizing activation ratio of quadriceps to hamstrings) may help individuals with CAI improving ankle stability and reduce atypical knee loading during landings.

AB - Second-generation antipsychotic agents (SGAs) cause serious metabolic side effects, including weight gain, dyslipidemia, and glucose metabolism abnormalities, which occur by unknown mechanisms. Therefore, the search for prospective markers for antipsychotic-induced weight gain (AIWG) has been of major interest. So far, predictive factors predisposing patients to the develop obesity and related metabolic disturbances induced by SGAs have been relatively less studied among large samples of Chinese schizophrenic patients. In this study, 264 Han Chinese inpatients diagnosed with schizophrenia or schizoaffective disorder initiated treatment with olanzapine (n=131) or risperidone (n=133) and were followed for 12weeks. Anthropometric measurements and laboratory analyses of thyroid hormone, fasting plasma glucose (FPG), and lipid levels were conducted as part of routine medical care. The results showed baseline thyroxine (T4) and waist:hip ratio (WHR)were negatively correlated to AIWG (T4: rs=-0.154, P=0.014; WHR: rs=-0.199, P=0.008). Correlations remained significant after multiple regression analyses. The two treatment groups statistically differed for changes in body mass index, WHR, LDL cholesterol, and FPG; in both groups FPG decreased at first and then increased. Our findings suggest basal T4 and WHR may serve as early biomarkers for weight gain as a side effect of single-SGA treatment. PMID- 29175721 TI - De-masking oxytocin-deficiency in craniopharyngioma and assessing its link with affective function. AB - Despite the high prevalence of panhypopituitarism and diabetes insipidus in patients with craniopharyngioma (CP), little is known about the functioning of the neuropeptide oxytocin in these patients. This is of special interest as tumor associated lesions often impair sites critical for oxytocin production and release, and affective dysfunction in CP links with elsewhere reported prosocial, antidepressant and anxiolytic oxytocin effects. Using a prospective study-design, we tested whether oxytocin is reduced in CP-patients, and whether altered oxytocin levels account for affective and emotional dysfunction. 26 adult CP patients and 26 healthy controls matched in sex and age underwent physical exercise, a stimulus previously shown to induce oxytocin release. Baseline and stimulated salivary oxytocin levels, as well as empathy, depression and anxiety scores were measured. Results showed that patients overall did not present with lower baseline oxytocin levels than controls (F[1,30]=0.21, p=0.649), but baseline oxytocin levels were indeed reduced in patients with hypothalamic damage, as assessed by MRI-based grading (F[2,9.79]=4.54, p=0.040). In response to exercise-induced stimulation, all CP-patients showed a blunted oxytocin release compared to controls (F[1,30]=9.36, p=0.005). DI was not associated with oxytocin levels. Regarding affective function, unexpectedly, higher baseline oxytocin was related to higher trait anxiety (b=2.885, t(43)=2.421, p=0.020, CI[.478; 5.292]); the positive link with higher depression failed to reach statistical significance (b=1.928, t(43)=1.949, p=0.058, CI[-0.070; 3.927]). A blunted oxytocin-release was linked with higher state anxiety (b=-0.133, t(43)= 2.797, p=0.008, CI[-0.230; -0.037]). Empathy was not associated with oxytocin measures. In conclusion, we observed reduced baseline oxytocin levels only in CP patients with hypothalamic damage. Exercise-induced stimulation de-masked an oxytocin-deficiency in all CP-patients. Baseline oxytocin levels and stimulated OT-responses might have different effects on affective function, which should be considered in future substitution paradigms. PMID- 29175722 TI - Significance of systemic immune-inflammation index in the differential diagnosis of high- and low-grade gliomas. AB - OBJECTIVE: Circulating biomarkers have been increasingly appreciated in the grading of gliomas. This study aimed to assess the value of the systemic immune inflammation index (SII) as a possible marker in the grading of gliomas. MATERIALS AND METHODS: In our study, 153 patients with gliomas were included-53 patients had histologically verified low grade gliomas (LGG) and 100 patients had high grade gliomas (HGG). Preoperative complete blood count (CBC) and clinicopathological data were collected. The optimal SII cut-off value for grading of gliomas was calculated by receiver operating characteristics curve (ROC) analysis. RESULTS: Based on the ROC analysis, the most optimal cut-off value of SII to distinguish HGG and LGG was determined as 392.48*109/L. For this cut-off value, SII had a sensitivity of 75%, specificity of 66%, and area under the curve (AUC) of 0.773. Furthermore, we found that patients in the high-SII group had a significantly higher Ki-67 index than that in patients in the low-SII group (P=0.002). CONCLUSION: Our results demonstrate that SII has a moderate diagnostic accuracy for differentiating HGG from LGG. More studies are needed to confirm these results. PMID- 29175723 TI - Brain tumors associated with psychogenic non-epileptic seizures: Case series. AB - OBJECTIVE: The association of psychogenic non-epileptic seizures (PNES) with primary or secondary brain tumors has not been well described in the literature. We aim to discuss their association, and their impact in brain tumor treatment. PATIENTS AND METHODS: We identified four patients retrospectively from our practice. The diagnosis of PNES was based on clinical suspicion and standard EEG, supplemented with video-EEG recording in 2 patients. RESULTS: The initial diagnosis of brain tumor was associated with a new onset seizure prior to diagnosis. The majority of the patients presented with ES followed by recurrent PNES during the course of their disease. Patients were treated with multiple anti epileptic drugs, requiring frequent schedule adjustments. The preferred tumor treatment modality was chemotherapy, followed by surgical resection. The patients were offered psychological consultation achieving partial control of their events. These patients manifested recurrent disabling clinical events that required multiple medical consultations. None of these patients presented clinical evidence of tumor progression at the time of PNES presentation. CONCLUSION: A high index of suspicion and early psychological consultation referral will likely mitigate the quality of life impact of PNES in these patients. PMID- 29175724 TI - A right amygdalohippocampectomy: A diagnostic challenge. AB - OBJECTIVE: Amygdalohippocampectomy (AHE) is the resective surgery for medically intractable mesial temporal lobe epilepsy. To date no study has investigated a wide range of neuropsychiatric symptoms in right AHE outpatients. PATIENTS AND METHODS: Three patients with right AHE participated in this study. The control group are patients with cognitive complaints with no history of epilepsy or neurological impairment and no structural abnormalities on the MRI/CT. We expected no difference in verbal memory compared to the controls. Concerning affective Theory of Mind (ToM) we expect a difference between controls and AHE patients. In terms of behavior it is expected that coping and behavioral questionnaires do not significantly differ between AHE and controls, but that proxies of AHE patients do report more behavioral/psychiatric symptoms. RESULTS: No significant difference was found between groups concerning the cognitive functions. For affective ToM we did find a significant difference (p=0.044). A significant difference for the use of more reassuring thoughts (p=0.006) and a trend for less passive reactions on the coping questionnaire, suggesting an 'active coping style'. Overall, AHE patients report fewer problems the self- reported questionnaires. Proxies of the AHE patients reported a trend for more behavioral disinhibition compared to proxy ratings of the control group. CONCLUSION: Right AHE patients underestimate their behavioral and emotional changes due to self-awareness deficits. Ratings of significant others are of immense importance for the detection of psychiatric and behavioral problems. Lesions in the amygdala- orbitofrontal cortex connection disrupt the emotional network, which might explain our results. PMID- 29175725 TI - Estimation of the number of contributors of theoretical mixture profiles based on allele counting: Does increasing the number of loci increase success rate of estimates? AB - DNA mixtures are more frequently encountered in casework due to increased kit sensitivity, protocols with increased cycle number, and requests for low copy number DNA samples to be tested. Generally, the first step in mixture interpretation is determining the number of contributors, with the most common approach of maximum allele count. Although there are previous studies regarding the accuracy of this approach, none have evaluated the accuracy with the newly expanded U.S. core STR loci. In this work, 4,976,355 theoretical mixture combinations were generated with the PowerPlex(r) Fusion 6C system which includes 23 autosomal STR loci and three Y-STR loci. The number of contributors could be correctly assumed for 100% two-person and 99.99% three-person mixtures, whereas, four-, five-, and six-person mixtures were correctly assumed in 89.7%, 57.3%, and 7.8% of mixtures, respectively. Y-STR analysis showed the 3 Y-STR markers are only accurate for two-person male mixtures (96.7%). This work demonstrates that maximum allele count using the expanded U.S. core loci is not much improved from previous smaller panels, reiterating that this method is not as accurate beyond three contributors. PMID- 29175726 TI - The redesigned Forensic Research/Reference on Genetics-knowledge base, FROG-kb. AB - The Forensic Resource/Reference on Genetics-knowledge base (FROG-kb) web site was introduced in 2011 and in the five years since the previous publication ongoing research into how the database can better serve forensics has resulted in extensive redesign of the database interface and functionality. Originally designed as a prototype to support forensic use of single nucleotide polymorphisms (SNPs), FROG-kb provides a freely accessible web interface that facilitates forensic practice and can be useful for teaching and research. Based on knowledge gained through its use, the web interface has been redesigned for easier navigation through the multiple components. The site also has functional enhancements, extensive new documentation, and new reference panels of SNPs with new curated data. FROG-kb focuses on single nucleotide polymorphisms (SNPs) and provides reference population data for several published panels of individual identification SNPs (IISNPs) and several published panels of ancestry inference SNPs (AISNPs). For each of the various marker panels with reference population data, FROG-kb calculates random match probabilities (RMP) and relative likelihoods of ancestry for a user-entered genotype profile (either completely or partially specified). Example genotype profiles are available and the User's Manual presents interpretation guidelines for the calculations. The extensive documentation along with ongoing updates makes FROG-kb a comprehensive tool in facilitating use of SNPs in forensic practice and education. An overview of the new FROG-kb with examples and material explaining the results of its use are presented here. PMID- 29175727 TI - A step towards a holistic assessment of soil degradation in Europe: Coupling on site erosion with sediment transfer and carbon fluxes. AB - Soil degradation due to erosion is connected to two serious environmental impacts: (i) on-site soil loss and (ii) off-site effects of sediment transfer through the landscape. The potential impact of soil erosion processes on biogeochemical cycles has received increasing attention in the last two decades. Properly designed modelling assumptions on effective soil loss are a key pre requisite to improve our understanding of the magnitude of nutrients that are mobilized through soil erosion and the resultant effects. The aim of this study is to quantify the potential spatial displacement and transport of soil sediments due to water erosion at European scale. We computed long-term averages of annual soil loss and deposition rates by means of the extensively tested spatially distributed WaTEM/SEDEM model. Our findings indicate that soil loss from Europe in the riverine systems is about 15% of the estimated gross on-site erosion. The estimated sediment yield totals 0.164 +/- 0.013Pgyr-1 (which corresponds to 4.62 +/- 0.37Mgha-1yr-1 in the erosion area). The greatest amount of gross on-site erosion as well as soil loss to rivers occurs in the agricultural land (93.5%). By contrast, forestland and other semi-natural vegetation areas experience an overall surplus of sediments which is driven by a re-deposition of sediments eroded from agricultural land. Combining the predicted soil loss rates with the European soil organic carbon (SOC) stock, we estimate a SOC displacement by water erosion of 14.5Tg yr-1. The SOC potentially transferred to the riverine system equals to 2.2Tgyr-1 (~15%). Integrated sediment delivery-biogeochemical models need to answer the question on how carbon mineralization during detachment and transport might be balanced or even off-set by carbon sequestration due to dynamic replacement and sediment burial. PMID- 29175728 TI - On the contributions of photorespiration and compartmentation to the contrasting intramolecular 2H profiles of C3 and C4 plant sugars. AB - Compartmentation of C4 photosynthetic biochemistry into bundle sheath (BS) and mesophyll (M) cells, and photorespiration in C3 plants is predicted to have hydrogen isotopic consequences for metabolites at both molecular and site specific levels. Molecular-level evidence was recently reported (Zhou et al., 2016), but evidence at the site-specific level is still lacking. We propose that such evidence exists in the contrasting 2H distribution profiles of glucose samples from naturally grown C3, C4 and CAM plants: photorespiration contributes to the relative 2H enrichment in H5 and relative 2H depletion in H1 & H6 (the average of the two pro-chiral Hs and in particular H6,pro-R) in C3 glucose, while 2H-enriched C3 mesophyll cellular (chloroplastic) water most likely contributes to the enrichment at H4; export of (transferable hydrogen atoms of) NADPH from C4 mesophyll cells to bundle sheath cells (via the malate shuttle) and incorporation of 2H-relatively unenriched BS cellular water contribute to the relative depletion of H4 & H5 respectively; shuttling of triose-phosphates (PGA: phosphoglycerate dand DHAP: dihydroacetone phosphate) between C4 bundle sheath and mesophyll cells contributes to the relative enrichment in H1 & H6 (in particular H6,pro-R) in C4 glucose. PMID- 29175729 TI - RNA regulons in cancer and inflammation. AB - Gene expression is the fundamental driving force that coordinates normal cellular processes and adapts to dysfunctional conditions such as oncogenic development and progression. While transcription is the basal process of gene expression, RNA transcripts are both the templates that encode proteins as well as perform functions that directly regulate diverse cellular processes. All levels of gene expression require coordination to optimize available resources, but how global gene expression drives cancers or responds to disrupting oncogenic mutations is not understood. Post-transcriptional coordination is controlled by RNA regulons that are governed by RNA-binding proteins (RBPs) and noncoding RNAs (ncRNAs) that bind and regulate multiple overlapping groups of functionally related RNAs. RNA regulons have been demonstrated to affect many biological functions and diseases, and many examples are known to regulate protein production in cancer and immune cells. In this review, we discuss RNA regulons demonstrated to coordinate global post-transcriptional mechanisms in carcinogenesis and inflammation. PMID- 29175730 TI - Formation and function of tissue-resident memory T cells during viral infection. AB - Memory T cells are an important component of the adaptive immune response. Tissue resident memory T cells (TRM) are a recently described subset of memory T cells that reside in peripheral tissues and are maintained independently of circulating subsets of memory T cells. Importantly, TRM are frequently found in barrier tissues that commonly serve as entry portals for pathogens such as viruses. Mounting evidence shows that TRM are superior to their circulating counterparts in conferring protective immunity against a wide range of viruses. In this review, we will discuss the role of TRM in controlling viral infection with a focus on CD8+ TRM, the factors that regulate differentiation and a potential role for TRM in future vaccine development. PMID- 29175731 TI - Consequences of perinatal infections with rubella, measles, and mumps. AB - Measles, mumps, and rubella have recently taken the stage as re-emerging diseases of public health importance-particularly in regards to the consequences seen with perinatal infections. Effective vaccination strategies have successfully reduced the spread of measles, mumps, and rubella in the United States, but a current trend of increased vaccination hesitancy, fear of vaccine safety, and spread of misconceptions surrounding the science of vaccines have led to a relative resurgence of these diseases in the developed world. This article aims to explore why measles, mumps, and rubella should continue to be on the radar of medical professionals, and why the study of these diseases is important for understanding other teratogenic viruses of public health importance. PMID- 29175732 TI - The precision of predicting the time of onset of parturition in the bitch using the level of progesterone in plasma during the preparturient period. AB - Precise prediction of the time of onset of parturition in the bitch is of clinical importance. Many parturition management cases in clinical practice are presented in the last two weeks of pregnancy without a reliable estimate of the parturition date. The aim of this study was to assess the value of a single progesterone level in the blood plasma from a preparturient bitch to predict the time of onset of parturition. The temporal relationship between the decrease in the plasma progesterone levels and the time of cervical dilatation (TCD)-which correlates to the onset of stage 1 of parturition-was evaluated in 25 bitches in the preparturient period. Among bitches destined to reach TCD within 12 h there is a 2% probability of having a plasma progesterone level of 15.8 nmoL/L or above and a 6% probability of having a level of 8.7 nmoL/L or above. Conversely, if the level is below 8.7 nmoL/L there is a 99% probability of reaching TCD within 48 h and if the level is below 3.18 nmoL/L there is a 100% probability of reaching TCD within 24 h. These results allow the veterinary obstetrician to make prompt decisions in the management of parturition. PMID- 29175733 TI - Examining the role of attachment in the relationship between childhood adversity, psychological distress and subjective well-being. AB - Childhood adversity is associated with a wide range of detrimental psychological consequences. This study examined the mediating role of relationship-specific attachment (avoidance and anxiety) in the associations between childhood adversity and both psychological distress and subjective well-being. University students (N=190) across the Republic of Ireland completed self-report measures including the Adverse Childhood Experiences scale, Experiences in Close Relationships - Relationship Structures scale, Depression Anxiety and Stress scales and measures of subjective well-being. One hundred and twenty-eight participants (67.4%) reported experiencing at least one adverse childhood experience. Childhood adversity was associated with symptoms of psychological distress and subjective well-being. All such associations were mediated by certain relationship-specific attachment dimensions. Of these, attachment anxiety in general relationships was the most prominent mediator for both psychological distress and subjective well-being. Attachment to one's father and to one's romantic partner did not mediate any association. These findings indicate that attachment, in particular relationships, is an important factor in the associations between childhood adversity and both psychological distress and subjective well-being as an adult. One's attachment anxiety in general relationships is particularly important in these associations. Therapeutic interventions addressing these attachment domains may offset the detrimental effects of childhood adversity. Future research is required using a longitudinal design. PMID- 29175734 TI - Plasma total cell-free DNA (cfDNA) is a surrogate biomarker for tumour burden and a prognostic biomarker for survival in metastatic melanoma patients. AB - INTRODUCTION: Tumour burden is a prognostic biomarker in metastatic melanoma. However, tumour burden is difficult to measure and there are currently no reliable surrogate biomarkers to easily and reliably determine it. The aim of this study was to assess the potential of plasma total cell free DNA as biomarker of tumour burden and prognosis in metastatic melanoma patients. MATERIALS AND METHODS: A prospective biomarker cohort study for total plasma circulating cell free DNA (cfDNA) concentration was performed in 43 metastatic melanoma patients. For 38 patients, paired blood collections and scan assessments were available before treatment and at first response evaluation. Tumour burden was calculated as the sum of volumes from three-dimensional radiological measurements of all metastatic lesions in individual patients. RESULTS: Baseline cfDNA concentration correlated with pre-treatment tumour burden (rho = 0.52, P < 0.001). Baseline cfDNA levels correlated significantly with hazard of death and overall survival, and a cut off value of 89 pg/MUl identified two distinct prognostic groups (HR = 2.22 for high cfDNA, P = 0.004). Patients with cfDNA >=89 pg/MUl had shorter OS (10.0 versus 22.7 months, P = 0.009; HR = 2.22 for high cfDNA, P = 0.004) and the significance was maintained when compared with lactic dehydrogenase (LDH) in a multivariate analysis. We also found a correlation between the changes of cfDNA and treatment-related changes in tumour burden (rho = 0.49, P = 0.002). In addition, the ratio between baseline cfDNA and tumour burden was prognostic (HR = 2.7 for cfDNA/tumour volume >=8 pg/(MUl*cm3), P = 0.024). CONCLUSIONS: We have demonstrated that cfDNA is a surrogate marker of tumour burden in metastatic melanoma patients, and that it is prognostic for overall survival. PMID- 29175736 TI - Brain structural connectivity during adrenarche: Associations between hormone levels and white matter microstructure. AB - Levels of the adrenal hormones dehydroepiandrosterone (DHEA), its sulfate (DHEAS), and testosterone, have all been linked to behavior and mental health during adrenarche, and preclinical studies suggest that these hormones influence brain development. However, little is known about how variation in these hormones is associated with white matter structure during this period of life. The current study aimed to examine associations between DHEA, DHEAS, and testosterone, and white matter microstructure during adrenarche. To avoid the confounding effect of age on hormone levels, we tested these associations in 87 children within a narrow age range (mean age 9.56 years, SD=0.34) but varying in hormone levels. All children provided saliva samples directly after waking and completed a diffusion-weighted MRI scan. Higher levels of DHEA were associated with higher mean diffusivity (MD) in a widespread cluster of white matter tracts, which was partially explained by higher radial diffusivity (RD) and partially by higher axial diffusivity (AD). In addition, there was an interaction between DHEA and testosterone, with higher levels of testosterone being associated with higher fractional anisotropy (FA) and lower MD and RD when DHEA levels were relatively high, but with lower FA and higher MD and RD when DHEA levels were low. These findings suggest that relatively early exposure to DHEA, as well as an imbalance between the adrenal hormones, may be associated with alterations in white matter microstructure. These findings highlight the potential relevance of adrenarcheal hormones for structural brain development. PMID- 29175735 TI - Prognostic impact of interval breast cancer detection in women with pT1a N0M0 breast cancer with HER2-positive status: Results from a multicentre population based cancer registry study. AB - BACKGROUND: Although human epidermal growth factor receptor 2 (HER2) overexpression is associated with poor prognosis, patients (pts) with pT1a N0M0 breast cancers (BCs) have an excellent outcome across all subtypes. Interval cancers (ICs) have poorer survival than screen-detected (SD) tumours, and an association has been reported between ICs and HER2 overexpression. We aimed to determine, in a general population of pT1a N0M0 BCs with known screening status, whether HER2-positive ICs have a poorer outcome than HER2-positive SD cancers. METHODS: We evaluated all incident pT1a N0M0 BCs (n = 874) collected in the Emilia-Romagna region (Italy) from 2003 to 2009 and diagnosed in women aged 50 69. Pts unexposed to screening, with unknown HER2 status and/or treated with adjuvant trastuzumab were excluded from analysis. RESULTS: Sixty-one percent of the BCs were SD, whereas 19% were ICs. BCs with high histologic grade, hormone receptor-negative or HER2-positive status (odds ratio=1.7; 95% confidence interval [CI]: 1.1-2.7) were more likely ICs. Median follow-up was 115 months. The 10-year invasive disease-free survival (iDFS) for HER2-positive ICs was lower than that for HER2-positive SD cancers: 75.0% (95% CI: 55.5%-94.5%) versus 93.8% (95% CI: 86.5%-100%). An interaction between ICs and HER2-positive status was found for poorer iDFS after adjusting for prognostic variables (HR = 5.3; 95% CI: 1.6-16.7). CONCLUSIONS: IC detection may identify pts with HER2-positive pT1a N0M0 tumours in whom the rate of recurrence justifies consideration for conventional, anti-HER2, adjuvant treatment. PMID- 29175737 TI - Contrastive study on porphyrinic iron metal-organic framework supported on various carbon matrices as efficient electrocatalysts. AB - Porphyrinic iron metal-organic framework (pFeMOF) was combined with different kinds of carbon matrices, including porous graphene (PG), ordered mesoporous carbon (OMC) and macroporous carbon (MPC) via a simple one-step hydrothermal method. The introduction of carbon substrates improves the electrical conductivity and stability of pFeMOF. The presence of carbon also reduces the size of pFeMOF crystallites, leading to more active sites. The catalysts were used to electrocatalysis of hydrogen evolution reaction (HER) and the reduction of hydrogen peroxide (H2O2). Electrochemical measurements show that pFeMOF/PG has better electrocatalytic efficiency than pFeMOF/OMC, pFeMOF/MPC and pFeMOF. The HER on pFeMOF/PG displays a small onset potential of -34.37 mV vs. reversible hydrogen electrode (RHE), a low Tafel slope of 73.06 mV dec-1, a small over potential of 154.71 mV at 10 mA cm-2. The catalytic effect for H2O2 is also satisfied. The linearity range of H2O2 is as wide as 5-4310 MUM, and the sensitivity is as high as 77.38 MUA mM-1. Such splendid performances may be attributed to the crumpled structure of PG leading to evenly and smaller pFeMOF. Furthermore, abundant hierarchical pores of pFeMOF/PG result in larger electrochemically surface areas. Our work may provide a new approach to design efficient non-precious metal catalysts. PMID- 29175738 TI - Hierarchical hollow MnO2 nanofibers with enhanced supercapacitor performance. AB - One dimensional (1D) hollow nanostructures have been considered as one of the most fascinating materials for supercapacitors. Herein, the hollow MnO2 nanofibers are successfully synthesized through a two-step process, in which the electrospun carbon nanofibers acted as sacrificial template. The resulting hollow nanofibers are composed of ultrathin MnO2 nanosheets, which can offer rich electrochemical active sites for electrochemical reactions. Importantly, the open and free interspaces among these ultrathin MnO2 nanosheets can significantly enhance the utilization of the active material even at high current density. Such unique hollow nanostructure endow the hollow MnO2 nanofibers electrode better electrochemical performance with specific capacitance of 291 F/g at 1 A/g, superior rate capability of ~73% (from 1 to 10 A/g), and excellent cycling stability of 90.9% retention after 5000 cycles, demonstrating the potential for practical application in energy storage devices. PMID- 29175740 TI - Attachment of Pt nanoparticles to a metal oxide surface using a thiol-carboxyl bifunctional molecule. AB - HYPOTHESIS: Molecular attachments to platinum have received far less study than binding to gold. Of particular interest is whether the binding of bifunctional molecules, containing both thiol and carboxyl groups, can attach platinum to surfaces such as metal oxides. EXPERIMENTS: Attachment of 4-mercaptobenzoic acid (4-MBA) to bulk and nanoparticulate platinum was studied by cyclic voltammetry (CV), Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). Platinum nanoparticles were attached to TiO2 using 4-MBA and probed for Pt loading and electrocatalytic activity. FINDINGS: Currents for reduction and oxidation of a standard redox couple on a Pt wire are sharply decreased when the Pt is previously exposed to 4-MBA, indicating bonding. This effect is not observed for benzoic acid. The absence of the SH stretching vibrational mode in Raman spectra of 4-MBA-modified Pt nanoparticles is consistent with sulfur-bonding of the molecules to the nanoparticle surface. High-resolution XPS studies of S and Pt core electrons show the formation of SPt bonds. Therefore, 4-MBA binds to Pt via the S atom but not via the carboxyl group, enabling Pt attachment to other surfaces such as metal oxides. 4-MBA increased both the amount of Pt bound to a TiO2 surface and the rate of a redox reaction on the surface. PMID- 29175739 TI - One-pot aqueous fabrication of reduced graphene oxide supported porous PtAg alloy nanoflowers to greatly boost catalytic performances for oxygen reduction and hydrogen evolution. AB - Herein, reduced graphene oxide supported porous PtAg alloy nanoflowers (PtAg NFs/rGO) were synthesized by a simple one-pot aqueous method using pyridinium based dicationic ionic liquid (1,4-bis(pyridinium)butane dibromide, Bpb-2Br) as the new structure-director and stabilizing agent. The products were characterized by a series of techniques. The obtained nanocomposite had more positive onset potential (1.03 V) for oxygen reduction reaction (ORR) in alkaline electrolyte than those of commercial Pt/C (50 wt%, 0.96 V) and home-made Pt nanoparticles (NPs)/rGO (Pt NPs/rGO, 0.97 V), showing the enhanced catalytic performance for hydrogen evolution reaction (HER) with the positive onset potential (-26 mV) and a small Tafel slope (31 mV dec-1) relative to Pt/C (-18 mV, 31 mV dec-1) and Pt NPs/rGO (-42 mV, 36 mV dec-1) in 0.5 M H2SO4. PMID- 29175741 TI - Responsive complex capsules prepared with polymerization of dopamine, hydrogen bonding assembly, and catechol dismutation. AB - Complex capsules were fabricated by combining the polymerization of dopamine with hydrogen-bonding layer-by-layer assembly (LbL) of dopamine-modified poly(acrylic acid) (PAA-dopa) and poly(vinylpyrrolidone) (PVPON). PDA(PAA-dopa/PVPON)n shell was cross-linked by dismutation reaction among catechol groups of polydopamine (PDA) and PAA-dopa. During LbL assembly, PAA-dopa and PVPON diffuse in the robust PDA pre-layer, and hence the complex capsules become soft and flexible. With the change of environmental pH value, the hydrogen bonds in PDA(PAA-dopa/PVPON)n capsules would dissociate or reconstruct, and thus the complex capsules exhibit pH-responsive swelling-shrinking behavior. With only one assembled bilayer, PDA(PAA-dopa/PVPON)1 capsules show a volume swelling ratio of 1.34 from pH 2.0 to pH 8.5. In addition, the complex capsules display controlled loading and release of Rhodamine 6G (R6G) as pH value changed, which can be considered as a potential candidate for drug delivery. PMID- 29175742 TI - Facile hydrothermal synthesis of carbon-coated cobalt ferrite spherical nanoparticles as a potential negative electrode for flexible supercapattery. AB - Battery type electrodes would replace the currently available pseudocapacitive electrodes by the cause of high energy density and long discharge time. In this regard, battery type carbon coated CoFe2O4 spherical nanoparticles is prepared by the facile hydrothermal method and tested as the possible negative electrode for supercapattery applications. The phase purity, electronic states of elements, and the presence of carbon is inferred through various sophisticated techniques. The calculated surface area of CoFe2O4 and carbon coated CoFe2O4 are found to be 9 and 26 m2 g-1, respectively. The morphological analysis confirms the formation of uniform CoFe2O4 nanospheres (~25 nm) with a thin layer of carbon coating (~2 nm). The amorphous carbon coating over CoFe2O4 nanosphere is identified via high resolution transmission electron microscope. The observed peak and plateau regions in the cyclic voltammogram and galvanostatic charge/discharge curves reveals the battery-type charge storage behaviour of the material. The carbon coated CoFe2O4 delivers the maximum length capacitance of 9.9 F m-1 at 1 mV s-1 with a useful lifespan over 5000 cycles. The electrochemical impedance spectroscopy reveals that the carbon-coated CoFe2O4 delivers the low charge transfer resistance than CoFe2O4. Further, the fabricated supercapattery provides the energy density of 160 * 10-8 Wh cm-1 at a power density of 67.2 MUW cm-1. As well as, the device shows 93% of coulombic efficiency and 75% of the specific capacitance retention over 11,000 cycles. Overall, it is believed that the carbon coated CoFe2O4 can serve as a good candidate for flexible supercapatteries.

AB - Difenoconazole is widely used to inhibit the growth of fungi, but its residue in the water environment may threaten ecosystem and human health. Here, 1H nuclear magnetic resonance (NMR) and LC-MS/MS based metabolomics and transcriptomics approaches were used to assess the response of zebrafish to difenoconazole exposure. Early life stages of zebrafish were exposed to difenoconazole at environmentally relevant concentrations for 168h. Their comparison with the control group suggested an adverse development and disturbance of steroid hormones and VTG. KEGG pathway analysis identified five biological processes on the basis of differentially expressed genes (DEGs), as well as altered metabolites and amino acids in zebrafish following difenoconazole exposure. These affected processes included energy metabolism, amino acids metabolism, lipid metabolism, nucleotide metabolism, and an immune-related pathway. Collectively, these results bring us closer to an incremental understanding of the toxic effects of difenoconazole on zebrafish in its early development, and lend support to the continued use of the early life stages of zebrafish as a classical model to evaluate underlying environmental risks of xenobiotics in aquatic organisms.

AB - In this paper the third-rank chromatic aberration coefficients of round electron lenses are analytically derived and numerically calculated by Mathematica. Furthermore, the numerical results are cross-checked by the differential algebraic (DA) method, which verifies that all the formulas for the third-rank chromatic aberration coefficients are completely correct. It is hoped that this work would be helpful for further chromatic aberration correction in electron microscopy.

AB - We introduce an extension of the Darwin-Howie-Whelan (DHW) equations for the case of coherent L12 precipitates in an FCC matrix. The equations are similar in form to the conventional DHW equations and are sufficiently general to account for the different translational variants of the precipitate phase as well as for the displacement fields of arbitrary lattice defects. An approximate scheme to perform fast and accurate image simulations using a pre-computed list of scattering matrices is also introduced. Finally, the results of diffraction pattern and image simulations are shown for two synthetic microstructures for a Ni-Al alloy generated using phase field simulations. The dynamical scattering equations reveal that the precipitate phase superlattice beams can propagate through the disordered matrix, but they are fully decoupled from the fundamental waves.

AB - The use of DNA barcodes for species identification is a common laboratory practice. However, PCR amplification of full-length DNA barcode in processed material is difficult because of severe DNA fragmentation. In this study, an adaptor ligation-mediated PCR protocol was derived to amplify sets of target DNA fragments isolated from two CCMG products. The specially designed adaptor with asymmetric strands and terminal modification avoids amplification of non-target DNA sequences. DNA extracted from Angelica sinensis and Panax notoginseng CCMG were ligated with the adaptors and amplified by an adaptor primer and a single universal barcode primer to obtain partial ITS2 sequence. Results showed that various length of DNA fragments within the ITS2 region were amplified and could be used to identify the concerned species. The adaptor ligation-mediated PCR is therefore a promising universal method for species identification in highly processed herbal products. PMID- 29175747 TI - Development and validation of a new HPLC-MS method for meglumine impurity profiling. AB - We report a new High Performance Liquid Chromatography-Mass Spectrometry (HPLC MS) method to rapidly detect and quantify meglumine by-products (specifically reducing sugar(s) and nitrogen impurities) that could be present in the meglumine samples. Meglumine is a secondary amine obtained from glucose and it is an excipient used as counter-ion in several pharmaceutical formulations, especially when the concentration of the active pharmaceutical ingredient (API) is so high that the sodium is not a suitable option. Moreover, the increased use of meglumine is related to its ability to improve solubility in aqueous solutions due to the presence of a large number of hydroxyl groups. Thus, even if meglumine is widely used as excipient in pharmaceutical formulations, its impurity profile has never been fully evaluated. Here, we propose the use of a commercial agent that specifically reacts with carbonyl compounds, 1-(4-aminobenzyl)-1,2,4 triazole, with the aim of improving the detection of reducing sugars, such as glucose, after an easy derivatization procedure. Finally, we describe the method validation and the analysis of the impurity profile of meglumine samples from different manufacturers. PMID- 29175748 TI - The reason leading to the increase of icariin in Herba Epimedii by heating process. AB - Icariin (ICA), a major flavonoid responsible for the pharmacological actions of Herba Epimedii, was found to be increased significantly after the heating process. The increase of ICA was considered to be due to the transformation of other flavonoids, in particular, epimedin (EPI) A-C. This novel study demonstrated that the increase of ICA in Epimedium. koreanum was induced mainly through the conversion of 3'''-carbonyl-2''-beta-l-quinovosyl icariin (CQICA) by deglycosylation during the heating process. Furthermore, the comparative analysis of the changes of CQICA and ICA in four raw Epimedium species (EPs) designated in the Chinese Pharmacopoeia revealed that the increase of ICA during the heating process was associated with the presence of CQICA in EPs. The present study provided scientific evidence for the conversion of CQICA into ICA, correcting the understanding of the transformation of EPI A-C into ICA. The results provided a reasonable scientific basis for the traditional use of processed Herba Epimedii, and might be helpful for the quality assessment of EPs. PMID- 29175749 TI - The effectiveness of Baby-CIMT in infants younger than 12 months with clinical signs of unilateral-cerebral palsy; an explorative study with randomized design. AB - AIM: To explore the effectiveness of baby-CIMT (constraint-induced movement therapy) and baby-massage for improving the manual ability of infants younger than 12 months with unilateral cerebral palsy (CP). METHOD: Infants eligible for inclusion were 3-8 months old with asymmetric hand function and at high risk of developing unilateral CP. Thirty-seven infants were assigned randomly to receive baby-CIMT or baby-massage. At one year of age 31 children were diagnosed with unilateral CP, 18 (8 boys, 6.1+/-1.7months) of these had received baby-CIMT and 13 (8 boys, 5.0+/-1.6months) baby-massage. There were two 6-week training periods separated by a 6-week pause. The Hand Assessment for Infants (HAI), Assisting Hand Assessment (AHA), the Parenting Sense of Competence Scale (PSCS) and a questionnaire concerning feasibility were applied. RESULTS: There was improvement in the "Affected hand score" of HAI from median 10 (6;13 IQR) to 13 (7;17 IQR) raw score in the baby-CIMT group and from 5 (4;11 IQR) to 6 (3;12 IQR) for baby massage with a significant between group difference (p=0.041). At 18-month of age, the median AHA score were 51 (38;72 IQR) after baby-CIMT (n=18) compared to 24 (19;43 IQR) baby-massage (n=9). The PSCS revealed an enhanced sense of competence of being a parent among fathers in the baby-CIMT group compared to fathers in the baby-massage (p=0.002). Parents considered both interventions to be feasible. CONCLUSION: Baby-CIMT appears to improve the unimanual ability of young children with unilateral CP more than massage.

PMID- 29175752 TI - Lack of generalizability of observational studies' findings for turnover time reduction and growth in surgery based on the State of Iowa, where from one year to the next, most growth was attributable to surgeons performing only a few cases per week. AB - STUDY OBJECTIVE: Three observational studies at large teaching hospitals found that reducing turnover times resulted in the surgeons performing more cases. We sought to determine if these findings are generalizable to other hospitals, because, if so, reducing turnover times may be an important mechanism for hospitals to use for growing caseloads. DESIGN: Observational cohort study. SETTING: 116 hospitals in Iowa with inpatient or outpatient surgery from July 1, 2013 through June 30, 2015. SUBJECTS: Surgeons in Iowa, each with a unique identifier among hospitals. MEASUREMENTS: The independent variable was the number of inpatient and outpatient cases that each surgeon performed each week during the first fiscal year beginning July 1, 2013. The dependent variables were surgeons' number of inpatient and outpatient surgical cases, and intraoperative work relative value units (RVU's) for outpatient cases, during the second fiscal year. MAIN RESULTS: The average hospital in Iowa had less than half of its growth from year 1 to year 2 in numbers of cases among surgeons who performed >2 cases per week in the baseline year (23.0%+/-2.5% [SE], P<0.0001 comparing mean to 50%). Less than half the growth in RVU's was among those surgeons (18.1%+/-2.2%, P<0.0001). The average hospital in Iowa had less than half of its growth in numbers of cases among surgeons who performed 2 or fewer cases per week at the hospital during the baseline year and >2 cases per week at other hospitals in the state during that year (24.4%+/-2.6%, P<0.0001). Less than half the growth in RVU's was among those surgeons (21.3%+/-2.5%, P<0.0001). CONCLUSIONS: Most (>=50%) annual growth in surgery, both based on the number of total inpatient and outpatient surgical cases, and on the total outpatient RVU's, was attributable to surgeons who performed 2 or fewer cases per week at each hospital statewide during the preceding year. Therefore, the strategic priority should be to assure that the many low-caseload surgeons have access to convenient OR time (e.g., by allocating sufficient OR time, and assigning surgeon blocks, in a mathematically sound, evidence-based way). Although reducing turnover times and anesthesia controlled times to promote growth will be beneficial for a few surgeons, the effect on total caseload will be small. PMID- 29175756 TI - Shared identity in organizational stress and change. AB - The social identity approach has been found very useful for the understanding of a range of phenomena within and across organizations. It has been applied in particular to analyze employees' stress and well-being at work and their reactions to organizational change. In this paper, we argue that there is a mismatch between the theoretical notion of shared identities in teams and organizations and empirical research, which largely focuses on the individual employee's identification with his or her social categories at work. We briefly review the literature in the two areas of stress and change and conclude with an agenda for future research. PMID- 29175753 TI - Chicoric acid prevents PDGF-BB-induced VSMC dedifferentiation, proliferation and migration by suppressing ROS/NFkappaB/mTOR/P70S6K signaling cascade. AB - Phenotypic switch of vascular smooth muscle cells (VSMCs) is characterized by increased expressions of VSMC synthetic markers and decreased levels of VSMC contractile markers, which is an important step for VSMC proliferation and migration during the development and progression of cardiovascular diseases including atherosclerosis. Chicoric acid (CA) is identified to exert powerful cardiovascular protective effects. However, little is known about the effects of CA on VSMC biology. Herein, in cultured VSMCs, we showed that pretreatment with CA dose-dependently suppressed platelet-derived growth factor type BB (PDGF-BB) induced VSMC phenotypic alteration, proliferation and migration. Mechanistically, PDGF-BB-treated VSMCs exhibited higher mammalian target of rapamycin (mTOR) and P70S6K phosphorylation, which was attenuated by CA pretreatment, diphenyleneiodonium chloride (DPI), reactive oxygen species (ROS) scavenger N acetyl-l-cysteine (NAC) and nuclear factor-kappaB (NFkappaB) inhibitor Bay117082. PDGF-BB-triggered ROS production and p65-NFkappaB activation were inhibited by CA. In addition, both NAC and DPI abolished PDGF-BB-evoked p65-NFkappaB nuclear translocation, phosphorylation and degradation of Inhibitor kappaBalpha (IkappaBalpha). Of note, blockade of ROS/NFkappaB/mTOR/P70S6K signaling cascade prevented PDGF-BB-evoked VSMC phenotypic transformation, proliferation and migration. CA treatment prevented intimal hyperplasia and vascular remodeling in rat models of carotid artery ligation in vivo. These results suggest that CA impedes PDGF-BB-induced VSMC phenotypic switching, proliferation, migration and neointima formation via inhibition of ROS/NFkappaB/mTOR/P70S6K signaling cascade. PMID- 29175755 TI - Catalytic efficiency is a better predictor of arsenic toxicity to soil alkaline phosphatase. AB - Arsenic (As) is an inhibitor of phosphatase, however, in the complex soil system, the substrate concentration effect and the mechanism of As inhibition of soil alkaline phosphatase (ALP) and its kinetics has not been adequately studied. In this work, we investigated soil ALP activity in response to As pollution at different substrate concentrations in various types of soils and explored the inhibition mechanism using the enzyme kinetics. The results showed that As inhibition of soil ALP activity was substrate concentration-dependent. Increasing substrate concentration decreased inhibition rate, suggesting reduced toxicity. This dependency was due to the competitive inhibition mechanism of As to soil ALP. The kinetic parameters, maximum reaction velocity (Vmax) and Michaelis constant (Km) in unpolluted soils were 0.012-0.267mMh-1 and 1.34-3.79mM respectively. The competitive inhibition constant (Kic) was 0.17-0.70mM, which was lower than Km, suggesting higher enzyme affinity for As than for substrate. The ecological doses, ED10 and ED50 (concentration of As that results in 10% and 50% inhibition on enzyme parameter) for inhibition of catalytic efficiency (Vmax/Km) were lower than those for inhibition of enzyme activity at different substrate concentrations. This suggests that the integrated kinetic parameter, catalytic efficiency is substrate concentration independent and more sensitive to As than ALP activity. Thus, catalytic efficiency was proposed as a more reliable indicator than ALP activity for risk assessment of As pollution. PMID- 29175754 TI - 8-Oxoguanine DNA glycosylase 1: Beyond repair of the oxidatively modified base lesions. AB - Oxidative stress and the resulting damage to genomic DNA are inevitable consequences of endogenous physiological processes, and they are amplified by cellular responses to environmental exposures. One of the most frequent reactions of reactive oxygen species with DNA is the oxidation of guanine to pre-mutagenic 8-oxo-7,8-dihydroguanine (8-oxoG). Despite the vulnerability of guanine to oxidation, vertebrate genes are primarily embedded in GC-rich genomic regions, and over 72% of the promoters of human genes belong to a class with a high GC content. In the promoter, 8-oxoG may serve as an epigenetic mark, and when complexed with the oxidatively inactivated repair enzyme 8-oxoguanine DNA glycosylase 1, provide a platform for the coordination of the initial steps of DNA repair and the assembly of the transcriptional machinery to launch the prompt and preferential expression of redox-regulated genes. Deviations/variations from this artful coordination may be the etiological links between guanine oxidation and various cellular pathologies and diseases during ageing processes. PMID- 29175757 TI - Identification and characterization of chemosensory gene families in the bark beetle, Tomicus yunnanensis. AB - The bark beetle, Tomicus yunnanensis (Coleoptera: Scolytinae), is a seriously destructive pest of Yunnan pine (Pinus yunnanensis) and is distributed solely in Southwestern China. It has been a challenge to control this pest owing to its resistance to chemical pesticides, which have been used as the main control strategy of this species in recent years. Since this approach will continue until an alternative mitigation strategy is implemented, it is essential to develop novel or improved biocontrol approaches. In the current study, we aimed to identify most, if not all, of the bark beetle's chemosensory genes, and to address their respective phylogenetic relationships and expression characteristics. Digital gene expression (DGE) profiling and a comparison of the profiles at three developmental stages yielded 40,287,265 clean reads and a large number of differentially expressed genes (DEGs), with 21 up- and 20 down regulated DEGs involved in chemoreception. Transcriptome of the three mixed stages revealed a total of 80 transcripts encoding chemosensory-related proteins comprising 45 odorant-binding proteins (OBPs), 12 chemosensory proteins (CSPs), 20 receptor proteins [9 odorant receptors (ORs), 8 gustatory receptors (GRs) and 3 ionotropic receptors (IRs)] and 3 sensory neuron membrane proteins (SNMPs). As many as 38 full-length sequences were acquired with a combination of transcriptomic analysis and rapid amplification of cDNA ends (RACE) strategy. Phylogenetic analysis showed that T. yunnanensis OBPs were clustered into four sub-groups: 27 Minus-C OBPs, 5 antennal binding proteins (ABPIIs), 10 Classic OBPs and one Plus-C OBP; meanwhile, the ORs were grouped into four clades (1, 2, 7b and Orco). Expression profiles revealed that 66 of 80 genes were detected in the three DGE libraries, and 15 soluble olfactory proteins were antennae predominant, possibly guiding olfactory-associated behaviors of this beetle. Taken together, our study has provided valuable data for further functional studies of this beetle and will facilitate the identification of potential molecular targets associated with chemosensory reception for use in biocontrol strategies. PMID- 29175758 TI - Photoprotective potential of metabolites isolated from algae-associated fungi Annulohypoxylon stygium. AB - Natural products, or secondary metabolites, obtained from fungal species associated with marine algae have been widely used in sunscreens due to their antioxidant activity and protective potential against solar radiation. The endophytic fungus isolated from Bostrychia radicans algae collected in the Rio Escuro mangrove, Sao Paulo State, Brazil, Annulohypoxylon stygium (Xylariaceae family) was studied to evaluate the photoprotective potential of its metabolites. The Annulohypoxylon genus can produce secondary metabolites with interesting cytotoxic, antibacterial and antioxidant properties and was never isolated before from a marine alga or had its metabolites studied for UV protection. The fungal culture (code As) extracted with dichloromethane: methanol (2:1) yielded 9 fractions (Asa to Asi) which were submitted to different chromatographic methodologies to obtain pure compounds, and to spectroscopic methodologies to elucidate their structures. Also, a screening was conducted to evaluate the qualitative production of the metabolites, besides the absorption in the UVA/UVB range, their photostability and phototoxicity potential using the 3T3 NRU phototoxicity test (OECD TG 432). This study led to the isolation of a novel compound, 3-benzylidene-2-methylhexahydropyrrolo [1,2-alpha] pyrazine-1,4-dione (1), from fractions Ase3 and Asf3; Ase1 was identified as 1-(1,3-Benzodioxol-5 yl)-1,2-propanediol (2), two metabolites were isolated as diastereomers (1S,2R)-1 phenyl-1,2-propanediol (3) from Asd2 and (1R,2R)-1-phenyl-1,2-propanediol (4) from Asd3, and Ase1 and 1,3-benzodioxole-5-methanol (5) from Asc1. The results obtained showed a great potential source of new molecules to be used as UVB filters in sunscreens, since substances 1-2 presented UVB absorption, had no phototoxic potential and were considered photostable. In conclusion, these compounds can be considered as a potential new class of molecules for photoprotection, since their photosafety and non-cytotoxicity were predicted using in vitro methods for topical use. Meanwhile, further efficacy assays shall be conducted for the establishment of their Sun Protection Factor (SPF). Also, this work provided new information concerning the metabolic profile of A. stygium, since it was possible to obtain two enantiomer compounds (3) and (4). One of them belonged to the same skeleton, but with a methylenedioxy moiety, showing the richest enzymatic pattern for this microorganism. PMID- 29175759 TI - A membrane bioreactor with iron dosing and acidogenic co-fermentation for enhanced phosphorus removal and recovery in wastewater treatment. AB - A novel phosphorous (P) removal and recovery process using a membrane bioreactor (MBR) with ferric iron dosing and acidogenic co-fermentation was developed for municipal wastewater treatment. The very different solubility of Fe(III)-P and Fe(II)-P complex and the microbial transformation of Fe(III) to Fe(II) were utilized for P removal and recovery. By means of Fe-induced precipitation, chemical P removal was effectively achieved by an MBR with a flat-plate ceramic membrane; however, the Fe(III)-P solids accumulated in the MBR that constituted a significant fraction of the activated sludge. Anaerobic co-fermentation of the MBR sludge and food waste in a side-stream allowed the extraction of P and Fe from the sludge into the supernatant. The P in the supernatant was recovered as a fertilizer resource, while the sludge was returned to the MBR tank. The experimental results show that by adding FeCl3 at 20 mg Fe/L into the influent of domestic wastewater, about 95.6% of total P could be removed by the MBR. One fifth (20%) of the sludge in the MBR was circulated daily through the side-stream fermenters for co-fermentation with cooked rice as the model food waste. The sludge underwent acidogenesis and dissimilatory iron reduction, resulting in a drop of the pH to below 5.0 and reduction of Fe(III) to Fe(II). Owing to the high solubility of the Fe(II)-P complex, P and Fe were then dissolved and released from the sludge into the supernatant. By simply adjusting the solution pH to 8.0, the P and Fe(II) in the supernatant readily re-precipitated to form vivianite for the P recovery. Using the iron dosing MBR and side-stream sludge fermentation, an overall P recovery efficiency of 62.1% from wastewater influent can be achieved, and the problem of inorganic build-up in the MBR is effectively alleviated. PMID- 29175760 TI - Inventory, loading and discharge of synthetic phenolic antioxidants and their metabolites in wastewater treatment plants. AB - Little is known about the occurrence and fate of synthetic phenolic antioxidants (SPAs) and their metabolites in wastewater treatment plants (WWTPs). In this study, inventory, source, mass loading, and discharge of five SPAs, including 2,6 di-tert-butyl-4-methylphenol (BHT) and four of its metabolites were examined, based on the concentrations determined in wastewater influent, primary effluent, final effluent, suspended particulate matter (SPM), and sludge collected from two WWTPs (denoted as WWTPA and WWTPB) in the Albany area of New York State. The respective median concentrations of sum of SPAs (SigmaSPAs = 6 compounds including metabolites) and SPA-metabolites (Sigmametabolites = 4 metabolites) were 2455-3330 and 290-465 ng/L in influents, and 1580-1604 and 511-822 ng/L in final effluents. Adsorption to sludge (SigmaSPAs ranged as 2420-4680 ng/g dry wt) accounted for ~1% of the SPA removal. The removal efficiency (RE) for BHT in WWTPs ranged between 62.3% and 76.2%, whereas negative REs were found for SPA metabolites ([-3020%]-[-65.6%]). WWTP-based mass loading of BHT accounted for ~4% 10% of the total production volume reported in the USA, whereas ~1.0% of the annual production of BHT was discharged from WWTP through effluents. BHT present in personal care products was estimated to explain for >91% of the mass loading source into WWTPs. PMID- 29175761 TI - An improved protocol for extracting extracellular polymeric substances from granular filter media. AB - Extracellular polymeric substances (EPS) are an important parameter in drinking water biofilters, and, to date, this is the first study to compare protocols from the literature for extracting EPS from granular filter media. Five extraction protocols were compared, and one was improved by varying the type of initial physical treatment and the shaking intensity, temperature, and time of incubation. Extracting EPS from granular filter media in triplicate by combining 2 g (wet weight) of filter media with 10 mL of extraction buffer (10 mM Tris, 10 mM EDTA, 2.5% NaCl, pH 8), vortexing for 1 min, and incubating for 4 h at 35 degrees C with shaking at 200 rpm yielded significantly higher EPS polysaccharide and/or protein concentrations than did protocols from the literature. This improved protocol extracted a significant fraction of the biofilm attached to sand but was less effective on biofilm attached to anthracite or granular activated carbon (GAC). A survey of 11 full-scale biofilters from the U.S. and Canada revealed that EPS polysaccharide and protein concentrations can vary over one order of magnitude, from 0.02 to 0.60 mg glucose/g total solids (TS) and 0.27 to 3.38 mg bovine serum albumin/g TS, respectively. Backwashing significantly lowered the biomass and EPS polysaccharide concentrations, but the majority of the biofilm remained attached to the filter media after backwashing, as expected. The fraction of EPS polysaccharides and proteins removed during backwashing did not differ between anthracite and GAC biofilters. The improved EPS extraction protocol can be utilized to investigate the role of EPS in biofilter performance. PMID- 29175762 TI - Chemical nanocavitation of surfaces to enhance the utility of stainless steel as a medical material. AB - While stainless steel is a broadly used alloy with interesting mechanical properties, its applications in medicine suffers from inherent biocompatibility limitations. An attractive opportunity to improve its performance is to alter its surface, but this has proven challenging. We now show how high range anodization conditions using H2SO4/H2O2 as an atypical electrolyte can efficiently nanocavitate the surface of both stainless steel SS304 and SS316 and create a topography with advantageous biomedical characteristics. We describe the structural and chemical features of the resulting surfaces, and propose a nanocorrosion/transpassivation/repassivation mechanism for its creation. Our approach creates a thin mesoporous layer of crystalline oxide that selectively promotes mammalian cell activity and limits bacterial adhesion. The modified surfaces favor the formation and maturation of focal adhesion plaques and environment-sensing filopodia with abundant extra small lateral membrane protrusions, suggesting an increase in membrane fluidity. These protrusions represent a yet undescribed cellular response. Such surfaces promise to facilitate the integration of implantable SS devices, in general. In addition, our strategy simultaneously provides a simple, commercially attractive way to control the adhesion of microorganisms, making nanostructured stainless steel broadly useful in hospital environments, in manufacturing medical devices, as well as offering possibilities for non-medical applications. PMID- 29175763 TI - Novel insights into microbial community dynamics during the fermentation of Central European ice wine. AB - Culture-dependent and culture-independent strategies were applied to investigate the microbiota of autumn undamaged and damaged berries, winter berries and ice wine must samples of Gruner Veltliner (Veltlinske zelene) from Small Carpathian wine-producing region. One hundred twenty-six yeasts and 242 bacterial strains isolated from several microbiological media (YPD, PDA, R2A, GYC, MRS and MRS-T) were clustered by ITS-PCR and subsequent Qiaxcel electrophoresis. Representatives of each cluster were identified by sequencing. The extracellular hydrolytic properties and intracellular activities of esterase and beta-glucosidase of isolates were assayed. The culture-independent approach permitted the analysis of extracted DNA and RNA coupling DGGE fingerprinting with construction of clone libraries (bacterial and fungal; DGGE-cloning). The combination of the two approaches provided comprehensive data that evidenced the presence of a complex microbiota in each analyzed sample. RNA and DNA analyses facilitated differentiation of living microorganisms from the entire microbiota. Diverse microbial communities colonized the autumn and winter berries. Generally, the combination of results obtained by the methods suggested that the must samples contained mainly Saccharomyces cerevisiae, Metschnikowia spp., Hanseniaspora uvarum, Lactococcus lactis and Leuconostoc spp. The strains exhibited interesting esterase and beta-glucosidase properties, which are important for aroma formation in wine. Fermentation strategies utilising these microorganisms, could be attempted in the future in order to modulate the ice wine characteristics. PMID- 29175764 TI - The effect of essential oils on microbial composition and quality of grass carp (Ctenopharyngodon idellus) fillets during chilled storage. AB - Antimicrobial and antioxidant effects of essential oils (oregano, thyme, and star anise) on microbial composition and quality of grass carp fillets were investigated. Essential oils treatment was found to be effective in inhibiting microbial growth, delaying lipid oxidation, and retarding the increase of TVB-N, putrescine, hypoxanthine, and K-value. Based on sensory analysis, shelf-life of grass carp fillets was 6days for control and 8days for treatment groups. Among the essential oils, oregano essential oil exhibited the highest antimicrobial and antioxidant activities. GC-MS analysis of essential oils components revealed that carvacrol (88.64%) was the major component of oregano essential oil. According to the results of high-throughput sequencing, Aeromonas, Glutamicibacter, and Aequorivita were the predominant microbiota in fresh control samples. However, oregano essential oil decreased the relative abundance of Aeromonas, while thyme and star anise essential oils decreased the relative abundance of Glutamicibacter and Aequorivita in fresh treated samples. The microbial composition of both control and treatment groups became less diverse as storage time increased. Aeromonas and Pseudomonas were dominant in spoiled samples and contributed to fish spoilage. Compared to the control, essential oils effectively inhibited the growth of Aeromonas and Shewanella in grass carp fillets during chilled storage. PMID- 29175765 TI - Consumer interest in environmental impact, safety, health and animal welfare aspects of modern pig production: Results of a cross-national choice experiment. AB - Are consumers interested in aspects of pig production and do they take these into account in their buying decisions when such information is available? Samples of consumers in Germany and Poland selected the two - for them - most important out of a list of ten production characteristics, relating to animal welfare, health and safety, and environmental issues. In a subsequent choice experiment, the relative weight these characteristics had in consumers' choices was estimated. Relative importance of production characteristics varied between consumer segments, with the production interested segment being bigger in Germany than in Poland. With the exception of one animal welfare related criterion in Germany, those production characteristics that consumers perceive as most important relate to health and safety aspects rather than to animal welfare and environmental impact. PMID- 29175766 TI - Estimation of pork quality in live pigs using biopsied muscle fibre number composition. AB - Here, we newly provided the parameters for estimating meat quality in live pigs using the muscle biopsy. The biopsied longissimus thoracis muscle was used to identify the muscle fibre characteristics (MFCs). Of the various MFCs in biopsied muscle, muscle fibre number (MFN) composition showed the greatest correlation with the MFCs in postmortem muscle (P<0.001). Moreover, the pigs cluster groups, based on the biopsied MFN composition, demonstrated statistically significant differences in meat quality traits such as muscle pH, drip loss, and meat colour (P<0.05). Therefore, we conclude that the MFN parameters in live pigs are closely related to the postmortem muscle metabolic rate and ultimately with the quality of meat. We suggest that the higher type I and lower type IIB MFN in biopsied muscle will result in better pork quality. PMID- 29175768 TI - Step-by-step manual for planning and performing bifurcation PCI: a resource tailored approach. AB - As bifurcation PCI can often be resource-demanding due to the use of multiple guidewires, balloons and stents, different technical options are sometimes being explored, in different local settings, to meet the need of optimally treating a patient with a bifurcation lesion, while being confronted with limited material resources. Therefore, it seems important to keep a proper balance between what is recognised as the contemporary state of the art, and what is known to be potentially harmful and to be discouraged. Ultimately, the resource-tailored approach to bifurcation PCI may be characterised by the notion of minimum technical requirements for each step of a successful procedure. Hence, this paper describes the logical sequence of steps when performing bifurcation PCI with provisional SB stenting, starting with basic anatomy assessment and ending with the optimisation of MB stenting and the evaluation of the potential need to stent the SB, suggesting, for each step, the minimum technical requirement for a successful intervention.

AB - This report explores the consequences of acoustic overexposures on hearing in noisy environments for two macaque monkeys trained to perform a reaction time detection task using a Go/No-Go lever release paradigm. Behavioral and non invasive physiological assessments were obtained before and after narrowband noise exposure. Physiological measurements showed elevated auditory brainstem response (ABR) thresholds and absent distortion product otoacoustic emissions (DPOAEs) post-exposure relative to pre-exposure. Audiograms revealed frequency specific increases in tone detection thresholds, with the greatest increases at the exposure band frequency and higher. Masked detection was affected in a similar frequency specific manner: threshold shift rates (change of masked threshold per dB increase in noise level) were lower than pre-exposure values at frequencies higher than the exposure band. Detection thresholds in sinusoidally amplitude modulated (SAM) noise post-exposure showed no difference from those in unmodulated noise, whereas pre-exposure masked detection thresholds were lower in the presence of SAM noise compared to unmodulated noise. These frequency dependent results were correlated with cochlear histopathological changes in monkeys that underwent similar noise exposure. These results reveal that behavioral and physiological effects of noise exposure in macaques are similar to those seen in humans and provide preliminary information on the relationship between noise exposure, cochlear pathology and perceptual changes in hearing within individual subjects.

METHODS AND RESULTS: Studies published in peer-reviewed journals before February 2017 were included and categorized according to the mechanism of thrombus removal: fragmentation, rheolytic therapy, aspiration or catheter-directed thrombolysis. Strengths, challenges and the level of evidence of each device were evaluated. We found 16 different catheter-based therapies for acute PE; all but one being used off-label. The majority of procedures involve catheter-directed thrombolysis. Aspiration therapy shows promise, but limited data are available. Rheolytic therapy should be used with caution, if at all, due to the high number of associated complications. CONCLUSIONS: Catheter-based therapies show promise as a treatment for acute PE, though evidence is lacking. Further research into the efficacy and safety of devices is needed.

AB - The industrial utilization of enzymes requires the high yield of enzyme production for the synthesis of polymers by microorganisms. Therefore, it is necessary to optimize different production parameters of levansucrase in order to increase its industrial applications. Zymomonas mobilis KIBGE-IB14 was considered as a promising candidate for the large scale production of levan among wide range of microorganisms. The current investigation is aimed to optimize the production parameters of levansucrase by Z. mobilis KIBGE-IB14 isolated from molasses. The results indicated that bacterial growth as well as enzyme production was greatly influenced by both physical and chemical conditions. It was revealed that high enzyme titers were achieved at 30 degrees C with pH 6.5 after 24 hours of incubation in a modified medium. Moreover, the enzyme exhibited its induction in the presence of sucrose used as a substrate. Thus, the present study demonstrated that newly isolated Z. mobilis KIBGE-IB14 can be used as a plausible producer of levansucrase for industrial applications.

AB - Ginger (Zingiber Officinale) is known over the centuries for its medicinal properties and has been used worldwide as health supplement and for treatment of several diseases. The purpose of this study was to evaluate the effects of whole ginger extract administration on spatial and recognition memory using experimental animal models. The antimicrobial properties of ginger extract against various pathogenic fungal and bacterial species were also examined. Aqueous extract of ginger at a dose of 500 mg/kg was orally administered to test rats and water was orally given to control rats for 6 weeks. Water Maze task (WM) was used to assess spatial memory and recognition memory of rats was evaluated by the Novel Object Recognition (NOR) task. Time spent with novel object was significantly increased in ginger treated rats as compared to control animals in novel object recognition task exhibiting enhanced recognition memory in ginger treated rats. Ginger treated rats exhibited significantly enhanced both short term memory and long term memory as evidenced by decrease in time to reach the hidden platform 1h and 24 h after training as compared to control rats. Short term memory functions of ginger treated rats were more enhanced than long term memory functions. Our findings suggest that ginger consumption may lead to an improvement in spatial and recognition memory. Significant activity of aqueous ginger extract was observed against pathogenic bacteria as well as fungal species. It is therefore suggested in this study that ginger extract can be used in microbial infections and as a memory enhancing drug in various memory disorders. PMID- 29175775 TI - Neuroprotective effect of Bacopa monnieri against morphine-induced histopathological changes in the cerebellum of rats. AB - Opioid addiction is associated with oxidative cell injury in neuronal cells. In this study, Bacopa monnieri (L.), a reputed nootropic plant, was evaluated against morphine-induced histopathological changes in the cerebellum of rats. B. monnieri methanolic extract (mBME) (40 mg/kg, p.o) and ascorbic acid (50 mg/kg, i.p) were administered two hours before morphine (20 mg/kg, i.p) for 14 and 21 days. The in vitro antioxidant activity of mBME was determined by 2,2-diphenyl-1 picrylhydrazyl (DPPH) free-radical scavenging assay. Morphine produced vacuolization of basket and stellate cells and reduced the size of Purkinje cells in the cerebellum after 14 days. However, treatment for 21 days was associated with severe shrinkage of Purkinje cells with loss of their characteristic flask shaped appearance as well as degeneration of basket, stellate and granule cells. Pretreatment with mBME and ascorbic acid for 14 and 21 days attenuated the morphine-induced histopathological changes in the cerebellum. The EC50 for the DPPH free-radical scavenging assay of mBME (39.06 MU/mL) as compared to ascorbic acid (30.25 MU/mL) and BHT (34.34 MU/mL) revealed that mBME strongly scavenged the free-radicals and thus possessed an efficient antioxidant propensity. These results concluded that B. monnieri having strong antioxidant activity exerted a protective effect against morphineinduced cerebellar toxicity.

AB - The aim of this study was to develop a Transdermal patch containing Cinnarizine using different ratios of hydrophilic and hydrophobic polymeric systems by solvent evaporation technique employing Polyethylene glycol (PEG 400) as plasticizer. The physicochemical compatibility of the drug and the polymers were studied by performing FT-IR spectroscopic analysis. Formulated patches were evaluated for physicochemical properties, skin irritation, in vitro drug release, ex-vivo permeation studies across rat abdominal skin and stability studies. The results of FT-IR studies revealed that there were no interactions between drug and polymers used. All the formulations exhibited uniformity in physicochemical properties. In vitro permeation studies of the formulations were performed by using Franz diffusion cells. Formulation F3 showed better permeation through rat skin (i.e., 8527.5+/-1.25MU/cm2 /hr) compared to rest of formulations and followed Fick's diffusion mechanism. On the basis of in-vitro drug release and ex vivo skin permeation performance, Formulation F3 containing the polymeric blend 19:1 Hydroxypropylmethyl Cellulose (HPMC E 50cps: Eudragit RL 100) has shown optimum release in comparison to other formulations and indicated good physical stability. So it has been demonstrated that Cinnarizine can be designed as matrix type transdermal drug delivery system (TDDS) and further in-vivo evaluations were required.

PMID- 29175778 TI - Characterization of pathogens involved in ventilator associated pneumonia in surgical and medical intensive care units - A single center experience. AB - In the present study 60 samples were collected from lower respiratory tract of patients suffering from Ventilator Associated Pneumonia (VAP) admitted in surgical and medical Intensive Care Units (ICUs) of Khyber Teaching Hospital, Peshawar, Pakistan. Recovered pathogens were characterized and their susceptibility pattern against commonly used antibacterial agents investigated. Most frequent bacterial pathogen found was methicillin- resistant Staphylococcus aureus (MRSA) (40%) followed by members of Enterobacteriaceae (22%; of which Escherichia coli (50%), Klebsiella pneumonia (30%), Enterobacter cloacae (10%) and Citrobacter freundii (10%), Pseudomonas aeruginosa 20% and Acinetobacter baumannii 18%. Majority of the specimens yielded polymicrobial growth (85.75% polymicrobial growth compared to 14.25% specimens yielding monomicrobial growth). The susceptibility pattern showed that A. baumannii was the most resistant bacterial pathogen. Based on the results of susceptibility pattern obtained in the present study, combination of linezolid with meropenem and colistin has been found to be the best combination option for empirical therapy for VAP pathogens in this region. PMID- 29175779 TI - Growth patterns of monosodium urate monohydrate (gouty and urinary) crystals in gel: An in vitro study. AB - Monosodium urate monohydrate crystals are deposited in peripheral joints causing gout and elicit an intense localized inflammatory attack whereas in collecting ducts and medullary interstitium as a urinary calculi which causes dysuria, nausea and hematuria. The purpose of present study is to observe possible growth patterns of monosodium urate monohydrate crystals. The crystals were grown in test tubes by single diffusion gel technique and were observed at 7th, 14th, 21st, 28th and 40th day. Needle and spherulite type crystals were observed at 14th day, while arboresque, crystal sheaves, densely branched, dumbbell, mushroom type spherulites, plumose and hexagonal prismatic crystals were observed for the first time. After 40th day complete spherulites were observed with their aggregates. The crystals were characterized by Scanning Electron Microscopy, Energy-Dispersive X-ray and Fourier Transform infra Red spectroscopies. The pattern of MSUM will be helpful to determine the role of different natural products in the modulation, inhibition or promotion of these crystals by affecting the shape, size, transparency, approximate number and total mass of growing crystals. In case of inhibition or modulation it will be helpful for evaluation the prophylactic management whereas the promotion of the crystal will give an idea about the risk factors of gout and kidney stones.

AB - Oxidative stress is a common pathological condition associated with drug-induced hepatotoxicity. This study investigated Spondias mombin L. aqueous leaf extract on reactive oxygen species and acetaminophen-mediated oxidative onslaught in rats' hepatocytes. Hepatotoxic rats were orally administered with the extract and vitamin C for 4 weeks. The extract dose-dependently scavenged DPPH, hydrogen peroxide and hydroxyl radicals, with IC50 values of 0.13, 0.66, and 0.64 mg/mL, and corresponding % inhibitions of 89, 80, and 90%, respectively at 1.0 mg/mL. Ferric ion was also significantly reduced. The marked (p<0.05) increases in the activities of alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase were reduced following treatment with the extract. The extract also significantly (p<0.05) induced the activities of antioxidant enzymes. These inductions reversed the acetaminophen-enhanced reduction in the specific activities of these enzymes as well as attenuated the observed elevated concentrations of autooxidized products and rived DNA in the acetaminophen intoxicated animals. The observed effects competed with those of vitamin C and are suggestive of hepatoprotective and antioxidative attributes of the extract. Overall, the data from the present findings suggest that S. Mombin aqueous leaf extract is capable of ameliorating acetaminophen-mediated oxidative hepatic damage via enhancement of antioxidant defense systems. PMID- 29175781 TI - In-silico identification and evaluation of plant flavonoids as dengue NS2B/NS3 protease inhibitors using molecular docking and simulation approach. AB - Dengue infection is prevailing among the people not only from the developing countries but also from the developed countries due to its high morbidity rate around the globe. Hence, due to the unavailability of any suitable vaccine for rigorous dengue virus (DENV), the only mode of its treatment is prevention. The circumstances require an urgent development of efficient and practical treatment to deal with these serotypes. The severe effects and cost of synthetic vaccines simulated researchers to find anti-viral agents from medicinal plants. Flavonoids present in medicinal plants, holds anti-viral activity and can be used as vaccine against viruses. Therefore, present study was planned to find anti-viral potential of 2500 flavonoids inhibitors against the DENVNS2B/NS3 protease through computational screening which can hinder the viral replication within the host cell. By using molecular docking, it was revealed that flavonoids showed strong and stable bonding in the binding pocket of DENV NS2B/NS3 protease and had strong interactions with catalytic triad. Drug capability and anti-dengue potential of the flavonoids was also evaluated by using different bioinformatics tools. Some flavonoids effectively blocked the catalytic triad of DENV NS2B/NS3 protease and also passed through drug ability evaluation. It can be concluded from this study that these flavonoids could act as potential inhibitors to stop the replication of DENV and there is a need to study the action of these molecules in-vitro to confirm their action and other properties. PMID- 29175782 TI - Improved in vitro and in vivo performance of carbamazepine enabled by using a succinic acid cocrystal in a stable suspension formulation. AB - Currently cocrystals are considered as an established approach for making crystalline solids with overall improved physico-chemical properties. However, some otherwise well behaving cocrystals undergo rapid dissociation during dissolution, with ultimate conversion to parent drug and thus apparent loss of improved solubility. The polymeric carriers are long known to manipulate this conversion during dissolution to parent crystalline drug, which may hinder or accelerate the dissolution process if used in a dosage form. The goal of this study was to deliver in vivo a more soluble carbamazepine-succinic acid (CBZ-SUC) cocrystal in suspension formulation utilizing Hydroxypropyl methyl cellulose (HPMC-AS) as a crystallization inhibitor and Polyvinyl carpolactam-polyvinyl acetate-polyethylene glycol graft copolymer (r) as solubilizer. The concentration of these polymers were systemically varied during in vitro dissolution studies, while selected formulations from dissolution studies were tested in vivo. Pharmacokinetic studies (PK) in rabbits demonstrated that formulation F7-X (1% cocrystal, 1% HPMC-AS and 2% Polyvinyl carpolactam-polyvinyl acetatepolyethylene glycol graft co-polymer(r)) caused almost 6fold improvement in AUC0-72 (***P k 0.05) as well as much higher Cmax of 4.73MU.mL-1 to that of 1.07MU.mL-1 of unformulated 'neat' cocrystal given orally. When reference formulation of CBZ (F5 X) with similar composition to F7-X were given to rabbits, cocrystal formulation gave 1.37fold (***P k 0.05) bioavailability than CBZ reference formulation. Cmax of reference formulation observed was 3.9MUmL-1. PMID- 29175783 TI - Total antioxidant capacity of commonly used fruits, vegetables, herbs and spices of Pakistan.

PMID- 29175784 TI - Antioxidant activity of different extracts from the aerial part of Moringa peregrina (Forssk.) Fiori, from Jordan. AB - The antioxidant activities of methanol (M), ethyl acetate (E) and hexane (H) extracts from leaves (L) and seeds (S) of Moringa (Moringa peregrina) were evaluated using different model systems in vitro. Free radical scavenging activities were assessed by measuring the scavenging activities of leaves and seeds different polar extracts separately using ABTS, Hydroxyl (OH) and DPPH radicals. Effect of extracts on ferrous ions chelating ability and total antioxidant capacity were also investigated for each extract. In addition, total phenolics, flavonoids and flavonols content of Moringa leaves and seeds extracts were determined. The leaves methanol (LM) extract showed significantly the highest DPPH radical scavenging activity (IC50value of 5.3+/-0.2MU/ml), followed by leaves ethylacetate extract (LE) and seeds methanolic extract (SM) with IC50 values of 7.1+/-0.2 and 7.2+/-0.4MU/ml, respectively. LE extract showed the highest ABTS radical scavenging activity with IC50value of 49.1+/-2.7MU/ml, followed by LM extract with IC50value of 61.2+/-1.2 MU/ml, whereas the highest hydroxyl radical (OH.) inhibition activity was found for LM and SM extracts with IC50 values of 76.9+/-0.8 and 77.5+/-1.2MU/ml, respectively. The total antioxidant activity was the highest in LM, LE and SM extracts (294.3, 244.5 and 231.6MU ascorbic acid equivalent for 1mg extract, respectively). LM, LE and SM extracts at concentration of 100MU/ml showed the highest chelating activity against ferrous ions (98.4, 91.1 and 90.7%, respectively). All Moringa leaves and seeds extracts showed pronounced antioxidant activities in a dose dependent manner and the effects depend strongly on the solvent used for extraction. The results showed that extracts of both leaves and seeds of Moringa exhibit antioxidant potential suggesting that M. peregrina is a promising plant. PMID- 29175785 TI - Does adherence to the therapeutic regimen associate with health related quality of life: Findings from an observational study of type 2 diabetes mellitus patients in Pakistan. AB - Patient adherence with a therapeutic regimen predicts successful treatment and reduces the severity of negative complications. The purpose of this work was to find the relationship between general Health Related Quality of Life (HRQoL) and compliance to the treatment among type 2 diabetes mellitus patients (T2DM) in Sargodha, Pakistan. The research was planned as a cross-sectional survey. T2DM patients attending a tertiary care institute in Sargodha, Pakistan were targeted for the study. The Urdu version of the Morisky Medication Adherence Scale (MMAS Urdu) and EuroQol Quality of Life Scale were employed to evaluate adherence to treatment regimen and HRQoL correspondingly. Descriptive statistics were used for the elaboration of socio-demographic characteristics. The Spearman rank order test was employed to determine the relationship between medicine adherence and HRQoL. P<0.05 was considered statistically significant. A total of 392 patients were selected for the survey. Most participants were males (n=222, 56.6%) with 5.58+/-4.09 years of history of T2DM. Majority of respondents (n=137, 34.9%) were categorized in age group of 51 to 60 years with mean age of 50.77+/-9.671 years. The present study highlighted that individuals with type 2 diabetes mellitus had decreased HRQoL (0.4715+/-0.3360) and poor medication adherence (4.44+/-1.8). Significant, yet weak positive correlations were observed between medication adherence and HRQoL (r=0.217 and 0.136 for EQ-5D and EQVAS respectively). Although the association between adherence to therapeutic regimen and HRQoL in the present study cohort was significant, it was rated as weak, hence failed in producing an overall impression on quality of life. The study highlights the need of identifying other individual factors affecting HRQoL among T2DM patients in Pakistan. PMID- 29175786 TI - Evaluation of cytotoxic and antiviral activities of aqueous leaves extracts of different plants against foot and mouth disease virus infection in farming animals. AB - Cytotoxic and antiviral activity of aqueous leaves extracts of three plants: Azadirachta indica, Moringa oleifera and Morus alba against Foot and Mouth disease virus (FMDV) were determined using MTT assay (3-(4, 5-Dimethylthiazol-2 yl)-2, 5-diphenyltetrazolium bromide). Eight different concentrations of each plant were evaluated. Cytotoxic and antiviral activity of each extract was evaluated as cell survival percentage and results were expressed as Means +/- S.D. From the tested plant extracts, Azadirachta indica & Moringa oleifera exhibited cytotoxicity at 200 & 100 MU/ml respectively. In case of antiviral assay, Moringa oleifera showed potent antiviral activity (p<0.05) while Azadirachta indica showed significant antiviral activity in the range of 12.5-50 MU/ml & 50-100 MU/ml respectively. In contrast no anti-FMDV activity in the present study was observed with Morus alba, although all the tested concentrations were found to be safe. PMID- 29175787 TI - Effect of medicinal plants, Heavy metals and antibiotics against pathogenic bacteria isolated from raw, Boiled and pasteurized milk. AB - Present study has been undertaken to isolate and identify the bacterial flora in raw, boiled and pasteurized milk. Agar disc diffusion method was used to determine their sensitivity using medicinal plants, antibiotics and heavy metals. Methylene blue reduction test was used to test the quality of milk samples. Total 10 pathogenic strains were isolated, five strains were isolated from raw milk, three from boiled milk and 2 two from pasteurized milk. To determine optimum conditions for growth, these pathogenic microorganisms were incubated at various temperatures and pH. Gram's staining and biochemical tests revealed that these pathogenic bacteria include Lactobacillus sp., E. coli, Salmonella sp., Pseudomonas sp., Streptococcus sp. and Staphylococcus. Ribotyping revealed S2 as Pseudomonas fluorescens, S5 as Lactococcus lactis and S9 as Lactobacillus acidophilus. Prevalence of pathogenic organisms provided the evidence that contamination of milk arises during milking, transportation and storage of milk. Raw milk is more contaminated than other two types of milk because it contains highest percentage of pathogenic organisms and pasteurized milk was found to be of best quality among three types. So it is recommended to drink milk after proper boiling or pasteurization. Proper pasteurization and hygienic packing of milk is essential to minimize contamination in milk which can save human beings from many milk borne diseases. Our study suggests that antimicrobial use in animal husbandry should be minimized to reduce the hazard of antibiotic resistance. Plant extracts are better alternative against pathogenic bacteria in milk.

AB - Ajwa, a variety of date palme Phoenix dactylifera L., has long been used and considered as one of the most popular fruits in the North Africa and Middle East region. For Muslims this fruit is of religious importance and is mentioned several times in Quran. Besides being a part of the Arabian essential diet, dates have been used traditionally for number of complications. This study aimed to evaluate the possible potential of Ajwa date extract to guard against carbon tetrachloride (CCL4)-induced liver damage in rats. Adult male Sprague-Dawley rats were given Ajwa date extract and silymarin (a standard reference drug) at doses of 300 & 50mg/kg, p.o., respectively for 2 weeks before CCl4 (2 ml/kg, s. c., twice weekly for 8 consecutive weeks), and concomitantly administered with CCl4 for 8 consecutive weeks. Like silymarin, Ajwa date extract produced significant decrease in serum levels of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total cholesterol, triglycerides (TG) and LDL cholesterol as well as lipid peroxides measured as malondialdehyde (MDA), hydroxyproline and caspase-3 contents of liver tissue with marked increase in serum albumin, HDL-cholesterol and reduced glutathione (GSH) content as well as enzyme activities of super oxide dismutase (SOD), catalase (CAT) and glutathione S-transferase (GST). In conclusion, Ajwa date extract afforded significant protection against CCl4-induced hepatocellular injury; an effect that could be attributed to its antioxidant, antiapoptotic and antifibrotic activities. PMID- 29175789 TI - Quality surveillance of immediate release aceclofenac tablets (100 mg) available in local market. AB - Aceclofenac is considered to be an effective drug that has been widely prescribed for multi-medical complaints globally. Owing to high demand many generic counterpart of aceclofenac tablets are now available in the commercial market. The aim of the present work is to evaluate and compare the quality attributes of various national/local brands of aceclofenac immediate release tablets (100mg) with the standard multi-national brand available in Pakistan. Physico-chemical evaluation was performed by determining the average tablet weight, thickness, hardness, disintegration time, percent dissolution and assay. Moreover, brands and reference formulation were exposed to multipoint dissolution. The in vitro drug release pattern was examined in various pH environment (1.2, 4.5 and 6.8) using USP dissolution apparatus 2 (paddle) at 50 rpm. The data was then analyzed by model dependent (Zero-order, first-order, Higuchi, Hixson-Crowell, Korsmeyer & Peppas, and Weibull model), pair wise procedure (f1 & f2) and one-way ANOVA methods. Results showed that the all aceclofenac brands and the reference tablets followed Weibull kinetics at pH 6.8. f1 & f2 were also found to be within the acceptable FDA limits. Furthermore, the values of One-way ANOVA also confirmed the absence of any significant difference among various aceclofenac brands. PMID- 29175790 TI - In vitro antimicrobial, antiprotozoal activities and heavy metals toxicity of different parts of Ballota pseudodictamnus (L.) Benth. AB - The study was done to check the antimicrobial and antiprotozoal activity of different parts of Ballota pseudodictamnus (L.) Benth. These activities were then compared with the heavy metals toxicity of different parts, which plants accumulate in different concentrations in different parts. In in-vitro antileishmanial results ethanolic extract, chloroform and ethyl acetate fractions in roots of Ballota pseudodictamnus (L.) Benth showed antileishmanial activity. The ethanol, n-butanol and ethyl acetate fraction in stem revealed inhibition of amastigote form of leishmania. The ethanolic extract, chloroform, and n-butanol fraction in leaves showed inhibition of leishmanial parasite. In heavy metals study, Chromium was above permissible value in all parts except in leaves. Nickel was above WHO limit in roots. Cadmium and lead were beyond permissible limits in entire plant parts. Results revealed that different parts of the plant have different inhibition properties. So each part of plant should be checked for antimicrobial and antiprotozoal assay separately. It is concluded that various metals accumulates with miscellaneous concentrations in different plant parts.

AB - Amommum subulatum (Roxb.) or Cardamom extract is known to have anti-inflammatory and neuroprotective effects towards many gastrointestinal related problems. However, uptill now different fractions of cardamom extract on fibroblasts with respect to potassium channel activity have not been investigated. Therefore, present study investigated the effects of different fractions of cardamom extract on potassium channels in non-tumor NIH3T3 cell line. Phytochemical analysis of hydroalcoholic, n-hexane, butane and ethyl acetate fractions of cardamom extracts were purified and isolated by thin layer chromatography (TLC). 3T3 cells were cultured and incubated with hydroalcohol (1-2 MU/ml), n-hexane (1 MU/ml), butane (2 MU/ml) and ethyl acetate (1-2 MU/ml) for 5 hrs at 37 degrees C. Modulation in potassium currents were recorded by whole-cell patch clamp method. The data showed two constituents Cineol (C10H18O) and Terpinyl acetate (C10H17OOCCH3) by TLC method. The present study shows that the constituents in n-hexane, hydro alcohol (1 MU/ml) and ethyl acetate (2 MU/ml) significantly increased (p<0.01) the potassium outward rectifying currents from NIH3T3 cells when compared to untreated controls cells. Whereas, butanol fraction (2 MU/ml) significantly decreased (p<0.01) the inward rectifying currents when compared to controls. Moreover hydroalcoholic and n-hexane fractions have increased the proliferation in 3T3 cell line. On the other hand butanol and ethyl acetate did not induce proliferation in 3T3 cells. Taken together, our data suggested that cardamom extract contains constituents that increased K+ currents, cell migration and proliferation and are involved in wound healing. PMID- 29175792 TI - Preliminary phytochemical screening, antioxidant and antihyperglycaemic activity of Moringa oleifera leaf extracts. AB - Moringa oleifera plant has been widely used for a vast number of folkloric medicinal purposes. The research aimed to investigate the antioxidant and antihyperglycaemic activity of Moringa oleifera leaf extracts obtained using different solvent systems for extraction. The solvent extracts of Moringa oleifera were: water extract (100% MoWE), 50% Methanolic extract (50% MoME), 100% Methanolic extract (100% MoME), 50% Ethanolic extract (50% MoEE), and 100% Ethanolic extract (100% MoEE). The in vitro antioxidant activity was evaluated by the use of the 1,1-diphenyl-2-picryl hydrazyl (DPPH) scavenging assay which showed the hydro-alcoholic extracts to have the highest reducing power, though lower than that of the standard, vitamin C. The hypoglyceamic activity was evaluated for the extracts at graded doses of 200mg/kg, 300mg/kg and 400mg/kg in wistar rats. Relative to the positive control, all treatment groups showed a significant statistical decrease in blood glucose levels. The decrease trends as metformin (84.14%) >50% MoEE 300mg/kg (83.72%) >MoWE 300mg/kg (82.42%) > 50% MoEE 200mg/kg (82.32%) >100% MoEE 400mg/kg (81.96%) >50% MoME (80.69%) >100% MoME 300mg/kg (78.47%) >50% MoME 200mg/kg (66.34%). Overall, the 50% MoEE at a dose of 300mg/kg showed superior antioxidant properties, weight restorative and pronounced hypoglyceamic effects. The weight restorative effect of high dose alcoholic extract of Moringa oleifera was also observed in the study. This study establishes novel and foundational considerations for further isolation and characterization studies for the hypoglyceamic compounds in the plant. PMID- 29175793 TI - Role of ALAD and VDR genotypes on the association of low blood lead level with serum uric acid and blood pressure in automobile paint workers of Karachi, Pakistan. AB - Lead is an environmental pollutant having nephrotoxic effects even at low level. Its continuous exposure is associated with increased serum uric acid level that resulting in renal insufficiency. This research was conducted to see the effects of delta-aminolevulinic acid dehydratase (ALAD) and vitamin D receptor (VDR) genotypes on biochemical parameters and blood pressure (BP) of automobile workers having low blood lead level (BLL) with continuous lead exposure. Automobile paints workers with ALAD 1-2 genotype showed the positive association of BLL with diastolic BP (p<0.05) whereas, a genotypic combination of ALAD 1-2/VDR BB showed the negative association of serum uric acid with BLL (p<0.05). Similarly negative effects of VDR BB genotype (p<0.01) and ALAD 1-2 genotype (p<0.05) were observed in the association of serum uric acid with BLL at the mean age >=30 years. This suggests that automobile paint workers having ALAD 1-2 genotypes are at the risk of increased diastolic BP. The research also foretells that combination of ALAD 1 2/VDR BB may play a significant role against lead induced nephrotoxicity at low BLL with continuous lead exposure. PMID- 29175794 TI - Cost effectiveness evaluation of hepatitis C therapy in Lahore. AB - Approximately 10 million Pakistan's of population is a victim of Hepatitis C virus. A comparative study of two treatments for Hepatitis C being provided in private clinics and government hospitals was conducted to evaluate the cost effectiveness of these treatments. The quality adjusted life years (QALYs) for each treatment plan was determined with the help of health utilities, using EQ-5D scores. A comprehensive data collection form aided in scrutinizing the cause and effect of each treatment on the patient's quality of life. The total sample size for this study is 200 total from the public and private sectors. For both the treatment strategies, values for quality adjusted life years (QALYs), incremental cost effective ratio (ICER) and cost effective analysis (CEA) were calculated. The Hepatitis C virus 3a and 3b genotypic patients who were treated with pegylated interferon alpha-2a and ribavirin combination (strategy 2) showed an increased quality adjusted life years (QALYs) of two years, as compared to those who received interferon alpha-2a and ribavirin regimen (strategy 1). An incremental cost effectiveness ratio (ICER) of Rs 144673.5 per quality adjusted life year (QALYs) was gained by patients treated with strategy 2. The therapy followed by the government sector (strategy 1) is relatively inexpensive accounting for Rs 654.5/quality adjusted life years (QALY) and therapy provided at the clinic sector (strategy 2) is relatively expensive Rs 5620.6/ quality adjusted life years (QALY). However, the cost effectiveness analysis for the pegylated interferon therapy is quite comparable with the other standard treatments; hence it can be called cost effective according to the quality adjusted life years (QALYs) gained and efficacy of the said therapy.

AB - In the present study the crude extracts of pollen of Centella asiatica (Linn.) Urban were explored for their antioxidant potential using Ferric Reducing Power, Metal Chelating Activity and Trolox Equivalent Antioxidant Capacity assays. In crude extracts of pollen antioxidant components were initially extracted in methanol and further fractionated in solvents of different polarity, such as n Hexane, Chloroform, Ethyl Acetate and Water exhibited reasonable antioxidant activity. The extract was found to contain large amounts of phenolic and flavonoid contents ranged from 143-1155 mg/l of gallic acid equivalent (GAE) and 911-2488 mg/l of quercetin (QE) respectively. Moreover, Super oxide Anion Radical Scavenging Activity and GS-MS analysis were also carried out. PMID- 29175796 TI - Antimicrobial susceptibility of organisms isolated from sputum culture of Karachi, Pakistan. AB - Our study aims to contribute to developing antibiotics prescription guidelines at a national and a regional level directed by the antibiotics susceptibility patterns and rapidly emerging resistant organisms. This study is designed to observe the antimicrobial susceptibility in sputum culture isolates and drug resistance patterns against various antimicrobials. This was a retrospective cohort study; data was collected from two laboratories from 1st Jan to 15 July 2007. All laboratory reports were analyzed using SPSS version 19.0.The sputum culture was found positive for microbial growth in 217 reports out of 864 total (25.11%). The leading organisms were 25.8% Klebsiella pneumoniae, 23.5% Streptococcus pneumoniae, 18% Pseudomonas aeruginosa and 12.9% Staphylococcus aureus. S.pneumoniae and S.aureus were sensitive to the combination of beta lactam antibiotics and anti-beta lactamase while K.pneumoniae and P. aureginosa were susceptible to fluoroquinolones, macrolides and aminoglycosides. The total yield of sputum culture was 25.11%. The gram positive cocci which were isolated were mostly resistant to beta lactam antibiotics alone i.e. only 45% of S. pneumoniae and 33% of S. aureus were sensitive to Amoxicillin alone. Sensitivity to Co-amoxiclav was still high. 90% and 85% of S. pneumonia and S. aureus respectively were sensitive to Co-amoxiclav. The P. aeruginosa resistance to Amikacin in our study is 10%.

AB - Hepatitis is the most common liver diseases in the Pakistan caused by blood-borne infection of HCV. Viral transmission is frequent through blood contact. Vertical transmission is transfer of disease from mother to infant. The women who are infected with hepatitis C virus RNA are at high risk of infecting their babies. Actual transmission occurs during labor and at time of delivery when blood of both mother and neonate is in contact with each other. Vertical transmission rate is lowered when mother is HCV RN A negative. The project was designed to determine the percentage of transmission and prevalence of Hepatitis C virus from mother to neonates. Assessment of the quantitative analysis of RNA levels in mother blood and viraemic status from the early postpartum period onwards of children born to HCV infected mothers. For the diagnosis of hepatitis C in mothers, blood samples of fifty HCV pregnant women between 23-41 years old were taken. The blood samples were centrifuged at 8,000 rpm and serum was separated and stored at 40C. The values of the Alanine Aminotransferase was determined at 2nd and 3rd trimester of pregnancy. After extraction HCVRN Awere transcribed and amplified by PCR. The samples were further authenticated through the Agarose Gel Electrophoresis system and bands were obtained. Nested reverse transcription PCR (RT-PCR) was conducted for the quantitative analysis of HCV-RNA. The results showed that in 66% cases, the mothers had high level of ALT at 2nd trimester of pregnancy. Their ALT level was decreased in the 3rd trimester of pregnancy. PCR results showed that 40% pregnant women had quantity of HCV-RNA in the range of 1000-10,000 IU/mL and in 18% women were above 100000 The results of spectrophotometer showed that 80% infants had the antibodies against HCV-RNA while only 20% of the neonates did not have antibody right after birth. The 29% babies got HCV-RNA in their serum and became positive for HCV-RNA. PMID- 29175798 TI - Report: Potential of nano-emulsions as phytochemical delivery system for food preservation. AB - Nature is a rich source of bioactive phytochemicals. These plant based compounds have rich scope as antioxidants, antimicrobial compounds and food preservatives and so for long time to be used in meat, fruits, vegetables and processed food items, either as added preservative or as coating material in various food applications, but the major limitation is their limited solubility in a food grade medium. Nano-emulsion is a best choice as a medium having vast area of application. The major advantage of nano-emulsion would be the solubility of a vast group of compounds, due to the presence of water and lipid phases. In this way, nano-emulsions can be proved to be the most suitable candidate as phytochemical delivery system for food preservation. In present article, the use of phytochemicals as potent food preservatives has been reviewed, in context of solubility of phytochemicals in nano-emulsion and applications of food grade nano emulsions to food systems. PMID- 29175799 TI - Report: Prevalence and antibiotic trials against Salmonella enterica isolated from diarrheic lambs and kids. AB - Salmonella enterica (S. enterica) is the major zoonotic threat for small ruminants and humans responsible for huge economic losses and high mortality in Pakistan. Lambs and kids of Lahore district were examined to determine the prevalence, hematology and chemotherapy of S. enterica. A total of 200 diarrheic samples (n=100 lambs; n=100 kids) were collected and examined; 59 (29.50%) were found positive for S. enterica. Lambs had lightly greater prevalence (31%) than kids (29%). The frequency analysis (OR=1.16 [reciprocal =0.87]) showed non significant difference in both the lambs and kids. The significant decrease (PR0.001) in hemoglobin, pack cell volume and total erythrocyte count was observed in infected lambs and kids. Results of in-vitro antibiotic susceptibility test revealed that S. enteric isolated from both lambs and kids were susceptible to levofloxacin, ciprofloxacin, ofloxacin, gentamicin, azithromycin, tobramycin, amoxicillin, ampicillin and nalidixic acid. Where as the results of in vivo antibiotic trials showed that isolates from both lambs and the kids with diarrhea were susceptible to levofloxacin and ciprofloxacin. PMID- 29175800 TI - Report: Computational drug designing of newly synthesized triazoles against potential targets of methicillin resistant Staphylococcus aureus. AB - Methicillin resistant Staphylococcus aureus (MRSA) is resistant to known antibiotics and has become a great challenge for healthcare professionals, therefore new molecules are needed to manage this situation. In this study, new lead molecules 4-Amino-5-(2-Hydroxyphenyl)-1,2,4-Triazol-3-Thione (U1) and4-(2 hydroxybenzalidine) amine-5-(2-hydroxy) phenyl-1,2,4-triazole-3-thiol(U1A Schiff base) were synthesized by fusion method that showed promising antibacterial activity (U1A: 26mm and U1: 14mm) against MRSA.FT-IR and NMR were used for structural characterization of these derivatives and their toxicity properties were assessed by Lipinski's rule of 5. New potential drug targets of this bacterium were also identified by comparative and subtraction genomics techniques. In particular, octanoyl-[GcvH]: protein N-octanoyl transferase and phosphor mevalonate kinase were used as potential targets in AutoDock Vina studies. This study can provide a framework to find potential drug targets for other pathogenic microorganisms that can successfully be docked with compound U1 and U1A. PMID- 29175801 TI - Report: Cytotoxic activities of Rosa brunonii, Calligonum polygonoides, Pegnum harmala and Sueda fruticosa extract using brine shrimp. AB - The present study was carried out to record and evaluate the effect of Rosa brunonii, Calligonum polygonoides, Sueda fruticosa and Pegnum harmala L., extracts on brine shrimp collected during March-June 2013 from different regions of District Bannu. These four plants were medicinal xerophytes and widely distributed throughout Pakistan. Rosa brunonii is commonly used as a hedge plant for gardening. Calligonum polygonoides and Sueda fruticosa are locally used as a fuel, while Pegnum harmala (L.) is the most important multipurpose medicinal xeric plant, which is used for various purposes. All these selected medicinal xerophytes have inhibitory effect on bacterial growth. In this study the effect of different concentration (10-70 MU/ml) were tested on brine shrimp. The results showed that maximum cytotoxic activities were observed in Rosa brunonii (100.0+/ 0.4), Calligonum polygonoides (100.0+/-0.2) and Pegnum harmala (L.) (90.0+/-5.2) while Sueda fruticosa (50.0+/-7.1) has less cytotoxic property. These activities are may be due to the presence of bioactive constituents. PMID- 29175803 TI - Review: Nanopreparations for better drug delivery. AB - Nanomedicines are a recent development to face medical and pharmaceutical challenges because nanoparticles have unique properties. They are very small in size and are easy to handle. One more advantage is that they are not harmful for the human body. Poorly soluble drugs have serious problems with their delivery and dosage forms. Formulation strategies by means of nanocarrier systems, such as polymeric micelles, can resolve the trouble. Micelles from PEG-diacyllipids, e.g. PEG-PE, are of special attention. On the other hand, the layer-by-layer (LbL) technique can be useful to set up stable nanocolloids of low solubility. In some cases, the use of nanopreparations is the only way to fulfill medical requirements. Thus, for the blood group CT imaging, one has to prepare long circulating contrast-loaded nanoparticles. In other cases, poor stability of potential drugs creates a problem, such as with siRNA, and the use of nanocarriers may present a solution e.g. Polymeric micelles having a hydrophobic derivative of siRNA. We will discuss the preparation, properties, and anti-cancer activity of drug-loaded PEG-PE micelles and LbL nanoparticles and other "approaches" for making "undeliverable" substances deliverable. Injectable, implantable, topical delivery of active compounds, oral drug delivery system and many other methods have been improved by nanotechnology. PMID- 29175802 TI - Review: Ethnomedicinal, phytochemical and antibacterial activities of medicinal flora of Pakistan used against Pseudomonas aeruginosa-A Review. AB - Medicinal plants have been used from ancient time against different infectious diseases caused by microorganisms across the globe. The present review represents different medicinal plants of Pakistan used traditionally for the treatment of variety of ailments caused by Pseudomonas aeruginosa, their in-vitro activities against P. aeruginosa and phytochemistry. These plants were extracted with different solvents that showed good in-vitro activities against P. aeruginosa, due to the presence of active phytoconstituents including alkaloids, terpenoids etc. Among all the solvents used for extraction process, alcoholic extracts were mostly preferred in Pakistan. However, non-alcoholic solvents like ethyl acetate and chloroform also showed good anti-P. aeruginosa activities. Statistically, increase in concentration (mg/ml) of ethyl acetate and chloroform extracts significantly increase (p=0.000 and p= 0.046) inhibitory activity against P. aeruginosa. This review provides scientific validation of the traditional knowledge in using medicinal plants for the treatment of different diseases caused by this bacterium. Reported Pakistani medicinal plants contain variety of phytochemical compounds that could be very useful in the production of new drugs with fewer side effects on living system compared to some allopathic drugs. This review also provides baseline information for future research studies on the phytochemistry of unexplored plants. Further research studies should be carried out on non-alcoholic extracts that could be helpful in the extraction new compounds, which could lead to the development of some novel drugs in the pharmaceutical industries of Pakistan. PMID- 29175804 TI - Review: Medicinal plants combating against hypertension: A green antihypertensive approach. AB - Hypertension (HTN) or high blood pressure is a medical condition that accounts 9.4 million deaths all over the world every year. It is leading cause of morbidity and mortality worldwide. It increases the risk of cardiovascular diseases, including heart failure, diffuse atherosclerosis, cognitive impairment and dementia. Clinically, synthetic antihypertensive drugs have been used to treat hypertension. However, the efficacy of these drugs is low and also produces side effects which include dry mouth, dizziness, emotional distress, gastrointestinal disturbance, visual disorders etc. These distressing side effects adversely affect health-related quality of life. Therefore, there is a need to search natural, cheaper and non-toxic compound. Plant are widely use in traditional systems of medicine for the treatment of several diseases. About 80% of the world population relies on traditional medicine for primary healthcare. In the last three decades, a lot of research has been done on local medicinal plants for hypotensive and antihypertensive potentials. Plants are the rich source of secondary metabolites which have been found in vivo to have antihypertensive properties. The current study is focused on reviewing the antihypertensive property of medicinal plants and their metabolites. In the current review, we conducted a literature search using Elsevier, Science direct, Springer Link (Springer), Pub Med and Google Scholar. The search included the keywords "plants", "medicinal plants", "plant extracts", cross-referenced with the keywords "hypertension" "antihypertensive activity". The use of plant origin natural compounds as cardio protective and antihypertensive agents is an interesting strategy for discovering bioactive products. Plants are rich in a variety of secondary metabolites, such as flavonoids, alkaloids, tannins and terpenoids. These have been found in vivo to have antihypertensive effects. The present review therefore; stand for a good basis to choose exact molecules belonging to the indicated categories that in the forthcoming future will become useful therapeutic tools. PMID- 29175805 TI - Review: Autologous blood transfusion drainage compared with no drainage in total knee arthroplasty: A meta-analysis and systematic review. AB - This is the first meta-analysis to assess the clinical efficiency, safety and potential advantages regarding the use of ABT drains compared with no drainage which is controversial in total knee arthroplasty (TKA).A comprehensive literature search was carried out in March 2015 using the PubMed, Embase, and Cochrane Library databases. A metaanalysis was carried out on two retrospective comparative studies (RCSs) and five randomized controlled trials (RCTs). The number of patients receiving homologous blood transfusion was the primary outcome of the meta-analysis; the secondary outcome measure was the mean drop in Hb level in comparison to the mean pre-operative HB level, the range of flexion of the knee joint, and infections of the wound after surgery. A total of 868 patients, who were included in two retrospective studies and five RCTs, were distributed into subgroups for the meta-analysis. This pooled data showed no benefit of ABT drainage compared no drainage in the homologous blood transfusion rate (13.05% and 16.91%, OR:0.73[0.47,1.13], Z=1.41, P=0.016; and 3.49% and 6.54%, OR: 0.50[0.12,2.01], Z=0.98,P=0.033,respectively in subgroups), Hb drop (Weight mean differences (WMD): 0.20[-0.28,0.68], Z=0.82, P=0.41; WMD:0.16[-0.41,0.55], Z=0.93, P=0.35, respectively), range of flexion of the knee joint (WMD:-0.82 [ 3.35,1.70], Z =0.64,P=0.52)and wound infection (OR:0.25[0.61,10.20]; Z =1.28, p=0.2) after TKA surgery. Our findings do not recommend the routine use of postoperative ABT drainage in total knee arthroplasty. Well-designed RCTs with large sample sizes, longer term measures and extensive follow-up period should be performed in the future to update the findings of this study. PMID- 29175806 TI - The Distribution of Different Types of Diabetes in Childhood: A Single Center Experience AB - OBJECTIVE: Type 1 diabetes (T1D) is the most common cause of diabetes in childhood but type 2 diabetes (T2D) and maturity onset diabetes of the young (MODY) are emerging as noteworthy causes of diabetes at young ages. The aim is to determine the distribution, trends and clinical features of the different types of diabetes in childhood in one tertiary center. METHODS: The records of children and adolescents aged 0-18 years who were diagnosed as "diabetes/persistent hyperglycemia" between January 1999 and December 2016, were reviewed. Clinical and laboratory characteristics of the patients at diagnosis and type of diabetes were recorded. RESULTS: The mean +/- standard deviation age of 835 patients (48.7% females) at diagnosis was 8.8+/-4.4 years. Eighty-four percent of the patients were diagnosed as T1D, 5.7% as T2D, 5.3% as clinical MODY and 5% as being cases of other types of diabetes. The frequency of diabetic ketoacidosis (DKA) and severe DKA in T1D were 48.4% and 11.6%, respectively. Fourteen patients (29.2%) with T2D presented with ketosis and two of them (4.2%) had DKA at diagnosis. Antibody positivity was 83.1% in T1D and 14.8% in T2D. A statistically significant increase in the frequency of T2D has clearly been demonstrated in recent years with a frequency of 1.9%, 2.4% and 7.9% in 1999-2004, 2005-2010 and 2011-2016, respectively (p<0.001). In MODY, genetic analysis was performed in 26 (59%) patients and HNF1A and GCK gene mutations were detected in 3 (11.5%) and 14 (53.8%) patients, respectively. CONCLUSION: Although the most frequent cause of DM is T1D in childhood, a trend towards increase in the frequency of T2D in recent years is notable in our population. PMID- 29175807 TI - Restless Legs Syndrome and Poor Sleep Quality in Obese Children and Adolescents AB - OBJECTIVE: Adult epidemiological studies suggest that the rate of Restless Legs syndrome (RLS) in the general population may range from 5% to 15%. The aim of this study was to investigate the frequency of RLS in a community sample of obese adolescents aged 10-16 years and to assess the association with sleep quality and health-related glucose metabolism markers. METHODS: The study group comprised 144 obese and overweight children aged 10-16 yearsand the control group consisted of 66 age-matched healthy children. The RLS Questionnaire devised by the International RLS Study and the Pittsburgh Sleep Quality Index (PSQI), where a score >5 indicates poor sleep quality, was used to assess sleep quality. RESULTS: Mean body mass index (BMI) of the overweight/obese and control groups were 30.5+/-0.5 and 18.7+/-0.2, respectively. The frequency of RLS was higher in the obese group (21.7%) than the overweight (3.4%) and control (1.5%) (p<0.001) groups. The frequency of a poor PSQI score was significantly higher (p<0.001) in the obese group (37.3%) than the control group (24.2%). The obese with RLS group also had poorer sleep quality scores than the non-RLS obese group. Many symptoms of sleep disruption were more common in obese patients with RLS and RLS was independently correlated with a high PSQI score [odds ratio (OR): 2.25, confidence interval (Cl): 0.96-5.28, p<0.001)] and an increased BMI z-score (OR: 8.87, Cl: 2.04-38.61, p<0.001). CONCLUSION: RLS is common in obese children and may be associated with altered sleep quality. Obese children with RLS need to be assessed since they may need support to improve their sleep quality. PMID- 29175808 TI - Time Gain Needed for In-Ambulance Telemedicine: Cost-Utility Model. AB - BACKGROUND: Stroke is a very time-sensitive pathology, and many new solutions target the optimization of prehospital stroke care to improve the stroke management process. In-ambulance telemedicine, defined by live bidirectional audio-video between a patient and a neurologist in a moving ambulance and the automated transfer of vital parameters, is a promising new approach to speed up and improve the quality of acute stroke care. Currently, no evidence exists on the cost effectiveness of in-ambulance telemedicine. OBJECTIVE: We aim to develop a first cost effectiveness model for in-ambulance telemedicine and use this model to estimate the time savings needed before in-ambulance telemedicine becomes cost effective. METHODS: Current standard stroke care is compared with current standard stroke care supplemented with in-ambulance telemedicine using a cost utility model measuring costs and quality-adjusted life-years (QALYs) from a health care perspective. We combine a decision tree with a Markov model. Data from the UZ Brussel Stroke Registry (2282 stroke patients) and linked hospital claims data at individual level are combined with literature data to populate the model. A 2-way sensitivity analysis varying both implementation costs and time gain is performed to map the different cost-effective combinations and identify the time gain needed for cost effectiveness and dominance. For several modeled time gains, the cost-effectiveness acceptability curve is calculated and mapped in 1 figure. RESULTS: Under the base-case scenario (implementation cost of US $159,425) and taking a lifetime horizon into account, in-ambulance telemedicine is a cost-effective strategy compared to standard stroke care alone starting from a time gain of 6 minutes. After 12 minutes, in-ambulance telemedicine becomes dominant, and this results in a mean decrease of costs by US -$30 (95% CI -$32 to -$29) per patient with 0.00456 (95% CI 0.00448 to 0.00463) QALYs on average gained per patient. In over 82% of all probabilistic simulations, in-ambulance telemedicine remains under the cost-effectiveness threshold of US $47,747. CONCLUSIONS: Our model suggests that in-ambulance telemedicine can be cost effective starting from a time gain of 6 minutes and becomes a dominant strategy after approximately 15 minutes. This indicates that in-ambulance telemedicine has the potential to become a cost-effective intervention assuming time gains in clinical implementations are realized in the future. PMID- 29175809 TI - Two Novel Cognitive Behavioral Therapy-Based Mobile Apps for Agoraphobia: Randomized Controlled Trial. AB - BACKGROUND: Despite the large body of literature demonstrating the effectiveness of cognitive behavioral treatments for agoraphobia, many patients remain untreated because of various barriers to treatment. Web-based and mobile-based interventions targeting agoraphobia may provide a solution to this problem, but there is a lack of research investigating the efficacy of such interventions. OBJECTIVE: The objective of our study was to evaluate for the first time the effectiveness of a self-guided mobile-based intervention primarily targeting agoraphobic symptoms, with respect to a generic mobile app targeting anxiety. METHODS: A Web-based randomized controlled trial (RCT) compared a novel mobile app designed to target agoraphobia (called Agoraphobia Free) with a mobile app designed to help with symptoms of anxiety in general (called Stress Free). Both interventions were based on established cognitive behavioral principles. We recruited participants (N=170) who self-identified as having agoraphobia and assessed them online at baseline, midpoint, and end point (posttreatment) over a period of 12 weeks. The primary outcome was symptom severity measured by the Panic and Agoraphobia Scale. RESULTS: Both groups had statistically significant improvements in symptom severity over time (difference -5.97, 95% CI -8.49 to 3.44, P<.001 for Agoraphobia Free and -6.35, 95% CI -8.82 to -3.87, P<.001 for Stress Free), but there were no significant between-group differences on the primary outcome (difference 0.38, 95% CI -1.96 to 3.20, P=.64). CONCLUSIONS: This is, to our knowledge, the first RCT to provide evidence that people who identify as having agoraphobia may equally benefit from a diagnosis-specific and a transdiagnostic mobile-based intervention. We also discuss clinical and research implications for the development and dissemination of mobile mental health apps.

PMID- 29175810 TI - Reduction in Vegetable Intake Disparities With a Web-Based Nutrition Education Intervention Among Lower-Income Adults in Japan: Randomized Controlled Trial. AB - BACKGROUND: No existing Web-based nutrition education interventions have been evaluated in light of socioeconomic status just in Japan. OBJECTIVE: The aim was to investigate the effect of a Web-based intervention program on reducing vegetable intake disparities between low- and middle-income Japanese adults. METHODS: In this randomized controlled trial, participants were assessed at three time points-baseline, postintervention (5 weeks later), and a follow-up after 3 months-from October 2015 to March 2016. We collected data via a Japanese online research service company from 8564 adults aged 30 to 59 years. Participants were stratified according to national population statistics for gender and age, and randomly selected. They were then randomly allocated into intervention (n=900) and control (n=600) groups such that both groups contained an equal number of individuals with low and middle income. The intervention program encouraged behavior change using behavioral theories and techniques tailored to their assumed stage of change. The outcome was vegetable intake servings per day (1 serving being approximately 70 g). RESULTS: Out of 900 participants who started, 450 were from the middle income group (of which 386 or 85.7% completed the intervention), and 450 were from the low income group (of which 371 or 82.4% completed). In the intervention group, vegetable intake increased in the low income participants from baseline to postintervention (0.42 servings, 95% CI 0.11 0.72). A two-way analysis of variance showed that low-income participants had significant main effects of group (eta2=0.04, P=.01) and time (eta2=0.01, P<.001), and a significant interaction (eta2=0.01, P=.009). Middle-income participants also had a significant main effect of time (eta2=0.01, P=.006) and a significant interaction (eta2=0.01, P=.046). CONCLUSIONS: This Web-based nutritional education intervention could fill the vegetable intake gap between low- and middle-income adults in Japan, and is expected to prevent noncommunicable and lifestyle-related diseases. Further intervention program improvements are necessary to maintain and increase vegetable intake for other groups.

PMID- 29175811 TI - Social Media Interventions to Promote HIV Testing, Linkage, Adherence, and Retention: Systematic Review and Meta-Analysis. AB - BACKGROUND: Social media is increasingly used to deliver HIV interventions for key populations worldwide. However, little is known about the specific uses and effects of social media on human immunodeficiency virus (HIV) interventions. OBJECTIVE: This systematic review examines the effectiveness of social media interventions to promote HIV testing, linkage, adherence, and retention among key populations. METHODS: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist and Cochrane guidelines for this review and registered it on the International Prospective Register of Systematic Reviews, PROSPERO. We systematically searched six databases and three conference websites using search terms related to HIV, social media, and key populations. We included studies where (1) the intervention was created or implemented on social media platforms, (2) study population included men who have sex with men (MSM), transgender individuals, people who inject drugs (PWID), and/or sex workers, and (3) outcomes included promoting HIV testing, linkage, adherence, and/or retention. Meta-analyses were conducted by Review Manager, version 5.3. Pooled relative risk (RR) and 95% confidence intervals were calculated by random-effects models. RESULTS: Among 981 manuscripts identified, 26 studies met the inclusion criteria. We found 18 studies from high-income countries, 8 in middle-income countries, and 0 in low-income countries. Eight were randomized controlled trials, and 18 were observational studies. All studies (n=26) included MSM; five studies also included transgender individuals. The focus of 21 studies was HIV testing, four on HIV testing and linkage to care, and one on antiretroviral therapy adherence. Social media interventions were used to do the following: build online interactive communities to encourage HIV testing/adherence (10 studies), provide HIV testing services (9 studies), disseminate HIV information (9 studies), and develop intervention materials (1 study). Of the studies providing HIV self-testing, 16% of participants requested HIV testing kits from social media platforms. Existing social media platforms such as Facebook (n=15) and the gay dating app Grindr (n=10) were used most frequently. Data from four studies show that HIV testing uptake increased after social media interventions (n=1283, RR 1.50, 95% CI 1.28-1.76). In the studies where social media interventions were participatory, HIV testing uptake was higher in the intervention arm than the comparison arm (n=1023, RR 1.64, 95% CI 1.19-2.26). CONCLUSIONS: Social media interventions are effective in promoting HIV testing among MSM in many settings. Social media interventions to improve HIV services beyond HIV testing in low- and middle-income countries and among other key populations need to be considered.

PMID- 29175812 TI - The Role of Transfer in Designing Games and Simulations for Health: Systematic Review. AB - BACKGROUND: The usefulness and importance of serious games and simulations in learning and behavior change for health and health-related issues are widely recognized. Studies have addressed games and simulations as interventions, mostly in comparison with their analog counterparts. Numerous complex design choices have to be made with serious games and simulations for health, including choices that directly contribute to the effects of the intervention. One of these decisions is the way an intervention is expected to lead to desirable transfer effects. Most designs adopt a first-class transfer rationale, whereas the second class of transfer types seems a rarity in serious games and simulations for health. OBJECTIVE: This study sought to review the literature specifically on the second class of transfer types in the design of serious games and simulations. Focusing on game-like interventions for health and health care, this study aimed to (1) determine whether the second class of transfer is recognized as a road for transfer in game-like interventions, (2) review the application of the second class of transfer type in designing game-like interventions, and (3) assess studies that include second-class transfer types reporting transfer outcomes. METHODS: A total of 6 Web-based databases were systematically searched by titles, abstracts, and keywords using the search strategy (video games OR game OR games OR gaming OR computer simulation*) AND (software design OR design) AND (fidelity OR fidelities OR transfer* OR behaviour OR behavior). The databases searched were identified as relevant to health, education, and social science. RESULTS: A total of 15 relevant studies were included, covering a range of game-like interventions, all more or less mentioning design parameters aimed at transfer. We found 9 studies where first-class transfer was part of the design of the intervention. In total, 8 studies dealt with transfer concepts and fidelity types in game-like intervention design in general; 3 studies dealt with the concept of second-class transfer types and reported effects, and 2 of those recognized transfer as a design parameter. CONCLUSIONS: In studies on game-like interventions for health and health care, transfer is regarded as a desirable effect but not as a basic principle for design. None of the studies determined the second class of transfer or instances thereof, although in 3 cases a nonliteral transfer type was present. We also found that studies on game-like interventions for health do not elucidate design choices made and rarely provide design principles for future work. Games and simulations for health abundantly build upon the principles of first-class transfer, but the adoption of second class transfer types proves scarce. It is likely to be worthwhile to explore the possibilities of second-class transfer types, as they may considerably influence educational objectives in terms of future serious game design for health.

PMID- 29175813 TI - Demands and Needs for Psycho-Oncological eHealth Interventions in Women With Cancer: Cross-Sectional Study. AB - BACKGROUND: Over the last decade, a growing body of studies regarding the application of eHealth and various digital interventions has been published and are widely used in the psycho-oncological care. However, the effectiveness of eHealth applications in psycho-oncological care is still questioned due to missing considerations regarding evidence-based studies on the demands and needs in cancer-affected patients. OBJECTIVE: This cross-sectional study aimed to explore the cancer-affected women's needs and wishes for psycho-oncological content topics in eHealth applications and whether women with cancer differ in their content topics and eHealth preferences regarding their experienced psychological burden. METHODS: Patients were recruited via an electronic online survey through social media, special patient Internet platforms, and patient networks (both inpatients and outpatients, University Hospital Tuebingen, Germany). Participant demographics, preferences for eHealth and psycho oncological content topics, and their experienced psychological burden of distress, quality of life, and need for psychosocial support were evaluated. RESULTS: Of the 1172 patients who responded, 716 were included in the study. The highest preference for psycho-oncological content topics reached anxiety, ability to cope, quality of life, depressive feelings, and adjustment toward a new life situation. eHealth applications such as Web-based applications, websites, blogs, info email, and consultation hotline were considered to be suitable to convey these content topics. Psychological burden did not influence the preference rates according to psycho-oncological content and eHealth applications. CONCLUSIONS: Psycho-oncological eHealth applications may be very beneficial for women with cancer, especially when they address psycho-oncological content topics like anxiety, ability to cope, depressive feelings, self-esteem, or adjustment to a new life situation. The findings of this study indicate that psycho-oncological eHealth applications are a promising medium to improve the psychosocial care and enhance individual disease management and engagement among women with cancer. PMID- 29175816 TI - TiO2 and ZrO2 in biomass conversion: why catalyst reduction helps. AB - Biomass refers to plant-based materials that are not used for food or feed. As an energy source, lignocellulosic biomass (lignin, cellulose and hemicellulose) can be converted into various forms of biofuel using thermal, chemical and biochemical methods. Chemical conversion implies the use of solid catalysts, usually oxide materials. In this context, reducible oxides are considered to be more active than non-reducible oxides. But why? Using density functional theory DFT + U calculations with the inclusion of dispersion forces, we describe the properties of anatase TiO2, a reducible oxide, and tetragonal ZrO2, a non reducible oxide, the (101) surfaces in this context. In particular, we focus on the role of surface reduction, either by direct creation of oxygen vacancies via O2 desorption, or by treatment in hydrogen. We show that the presence of reduced centres on the surface of titania or zirconia (either Ti3+ or Zr3+ ions, or oxygen vacancies) results in lower barriers and more stable intermediates in two key reactions in biomass catalytic conversion: ketonization of acetic acid (studied on ZrO2) and deoxygenation of phenol (studied on TiO2). We discuss the role of Ru nanoparticles in these processes, and in particular in favouring H2 dissociation and hydrogen spillover, which results in hydroxylated surfaces. We suggest that H2O desorption from the hydroxylated surfaces may be a relevant mechanism for the regeneration of oxygen vacancies, in particular on low coordinated sites of oxide nanoparticles. Finally, we discuss the role of nanostructuring in favouring oxide reduction, by discussing the properties of ZrO2 nanoparticles of diameter of about 2 nm.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'. PMID- 29175817 TI - Producing membrane proteins one simulation at a time. AB - Integral membrane proteins are studied with a number of structural and biophysical techniques, many requiring protein overexpression to reach sufficient quantities. However, achievement of the overexpression of membrane proteins is not necessarily straightforward, and the mechanisms and factors that influence expression are not clearly understood. A new study has now broken through this uncertainty by demonstrating the capability of coarse-grained simulations of membrane protein insertion to predict protein expression levels in Escherichia coli. PMID- 29175819 TI - Decreased oxygen exposure during transportation of newborns. AB - Oxygen is the most common treatment for newborns in need of respiratory support. However, oxygen can cause tissue injury through reactive oxygen species formation, especially in premature infants with reduced antioxidant defences, and may result in short-term and long-term toxic effects in multiple organ systems. Although most hospitals have the capability to tightly control oxygen delivery to hospitalised neonates, in many circumstances, the need is overlooked during infant transport. Lack of awareness of harm or appropriate medical equipment invariably results in excessive oxygen exposure. We developed a quality improvement programme to decrease oxygen exposure to newborns during their transportation, thus improving patient safety and quality of care.

AB - AIM: To examine the association between corticosteroid use in paediatric intensive care units (PICU) and subsequent symptoms of post-traumatic stress disorder (PTSD). METHODS: The subjects were children aged 8-16 years admitted to PICU with sepsis, meningoencephalitis (ME) and other disorders. Illness information was extracted from case notes; 3-6 months post discharge children completed a PTSD symptom questionnaire (eight-item Impact of Events Scale (IES 8)) assessing intrusion and avoidance symptoms. Saliva samples were also collected for cortisol profile analysis. RESULTS: 53 children completed the IES-8 questionnaires. 33 provided saliva samples. 19 (36%) received corticosteroids. In children with sepsis (n=15), corticosteroid use was associated with significantly lower PTSD intrusion symptom scores. There was a trend towards an association between corticosteroid use and lower evening cortisol levels. There was a comparable but weaker trend in children with ME. DISCUSSION: Corticosteroid use may be associated with fewer PTSD symptoms and lower evening cortisol levels following PICU admission in children with sepsis.

AB - In this review, we outline the standard of care for children in the UK with the most common major bleeding disorder, haemophilia, and how exciting new developments in therapy have the potential for further improvements in quality of life and clinical outcome. The combination of comprehensive specialist medical care, safer factor concentrates, earlier introduction of prophylaxis and patient specific education has allowed the current generation of patients with haemophilia to grow into adulthood with excellent joint function, pursuing full time employment with a good quality of life. We are entering an exciting new phase in paediatric haemophilia as potentially life-changing products appear on the scene taking a step towards achieving better, easier and personalised prophylaxis. PMID- 29175824 TI - Patterns of pain over time among children with juvenile idiopathic arthritis. AB - OBJECTIVES: Pain is a very common symptom of juvenile idiopathic arthritis (JIA). Disease activity alone cannot explain symptoms of pain in all children, suggesting other factors may be relevant. The objectives of this study were to describe the different patterns of pain experienced over time in children with JIA and to identify predictors of which children are likely to experience ongoing pain. METHODS: This study used longitudinal-data from patients (aged 1-16 years) with new-onset JIA. Baseline and up to 5-year follow-up pain data from the Childhood Arthritis Prospective Study (CAPS) were used. A two-step approach was adopted. First, pain trajectories were modelled using a discrete mixture model. Second, multinomial logistic regression was used to determine the association between variables and trajectories. RESULTS: Data from 851 individuals were included (4 years, median follow-up). A three-group trajectory model was identified: consistently low pain (n=453), improved pain (n=254) and consistently high pain (n=144). Children with improved pain or consistently high pain differed on average at baseline from consistently low pain. Older age at onset, poor function/disability and longer disease duration at baseline were associated with consistently high pain compared with consistently low pain. Early increases in pain and poor function/disability were also associated with consistently high pain compared with consistently low pain. CONCLUSIONS: This study has identified routinely collected clinical factors, which may indicate those individuals with JIA at risk of poor pain outcomes earlier in disease. Identifying those at highest risk of poor pain outcomes at disease onset may enable targeted pain management strategies to be implemented early in disease thus reducing the risk of poor pain outcomes. PMID- 29175825 TI - Reconstruction of head impacts in FIS World Cup alpine skiing. AB - INTRODUCTION: Prior to the 2013/2014 season, the International Ski Federation (FIS) increased the helmet testing speed from 5.4 to 6.8 m/s for alpine downhill, super-G and giant slalom. Whether this increased testing speed reflects head impact velocities in real head injury situations on snow is unclear. We therefore investigated the injury mechanisms and gross head impact biomechanics in seven real head injury situations among World Cup (WC) alpine skiers. METHODS: We analysed nine head impacts from seven head injury videos from the FIS Injury Surveillance System, throughout nine WC seasons (2006-2015) in detail. We used commercial video-based motion analysis software to estimate head impact kinematics in two dimensions, including directly preimpact and postimpact, from broadcast video. The sagittal plane angular movement of the head was also measured using angle measurement software. RESULTS: In seven of nine head impacts, the estimated normal to slope preimpact velocity was higher than the current FIS helmet rule of 6.8 m/s (mean 8.1 (+/-SD 0.6) m/s, range 1.9+/-0.8 to 12.1+/-0.4 m/s). The nine head impacts had a mean normal to slope velocity change of 9.3+/-1.0 m/s, range 5.2+/-1.1 to 13.5+/-1.3 m/s. There was a large change in sagittal plane angular velocity (mean 43.3+/-2.9 rad/s (range 21.2+/-1.5 to 64.2+/-3.0 rad/s)) during impact. CONCLUSION: The estimated normal to slope preimpact velocity was higher than the current FIS helmet rule of 6.8 m/s in seven of nine head impacts. PMID- 29175826 TI - Cluster analysis of novel isometric strength measures produces a valid and evidence-based classification structure for wheelchair track racing. AB - BACKGROUND: The Para athletics wheelchair-racing classification system employs best practice to ensure that classes comprise athletes whose impairments cause a comparable degree of activity limitation. However, decision-making is largely subjective and scientific evidence which reduces this subjectivity is required. AIM: To evaluate whether isometric strength tests were valid for the purposes of classifying wheelchair racers and whether cluster analysis of the strength measures produced a valid classification structure. METHODS: Thirty-two international level, male wheelchair racers from classes T51-54 completed six isometric strength tests evaluating elbow extensors, shoulder flexors, trunk flexors and forearm pronators and two wheelchair performance tests-Top-Speed (0 15 m) and Top-Speed (absolute). Strength tests significantly correlated with wheelchair performance were included in a cluster analysis and the validity of the resulting clusters was assessed. RESULTS: All six strength tests correlated with performance (r=0.54-0.88). Cluster analysis yielded four clusters with reasonable overall structure (mean silhouette coefficient=0.58) and large intercluster strength differences. Six athletes (19%) were allocated to clusters that did not align with their current class. While the mean wheelchair racing performance of the resulting clusters was unequivocally hierarchical, the mean performance of current classes was not, with no difference between current classes T53 and T54. CONCLUSIONS: Cluster analysis of isometric strength tests produced classes comprising athletes who experienced a similar degree of activity limitation. The strength tests reported can provide the basis for a new, more transparent, less subjective wheelchair racing classification system, pending replication of these findings in a larger, representative sample. This paper also provides guidance for development of evidence-based systems in other Para sports. PMID- 29175827 TI - Poor overall quality of clinical practice guidelines for musculoskeletal pain: a systematic review. AB - OBJECTIVES: Undertake a systematic critical appraisal of contemporary clinical practice guidelines (CPGs) for common musculoskeletal (MSK) pain conditions: spinal (lumbar, thoracic and cervical), hip/knee (including osteoarthritis) and shoulder. DESIGN: Systematic review of CPGs (PROSPERO number: CRD42016051653).Included CPGs were written in English, developed within the last 5 years, focused on adults and described development processes. Excluded CPGs were for: traumatic MSK pain, single modalities (eg, surgery), traditional healing/medicine, specific disease processes (eg, inflammatory arthropathies) or those that required payment. DATA SOURCES AND METHOD OF APPRAISAL: Four scientific databases (MEDLINE, Embase, CINAHL and Physiotherapy Evidence Database) and four guideline repositories. The Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument was used for critical appraisal. RESULTS: 4664 records were identified, and 34 CPGs were included. Most were for osteoarthritis (n=12) or low back pain (n=11), most commonly from the USA (n=12). The mean overall AGREE II score was 45% (SD=19.7). Lowest mean domain scores were for applicability (26%, SD=19.5) and editorial independence (33%, SD=27.5). The highest score was for scope and purpose (72%, SD=14.3). Only 8 of 34 CPGS were high quality: for osteoarthritis (n=4), low back pain (n=2), neck (n=1) and shoulder pain (n=1). PMID- 29175828 TI - Retrograde 3D rotational venography (3DRV) for venous sinus stent placement in idiopathic intracranial hypertension. AB - BACKGROUND: Dural venous sinus stenting has emerged as an effective and durable treatment for idiopathic intracranial hypertension (IIH). Improved visualization of the venous sinuses can improve stent placement. METHODS: We present two cases of IIH treated with venous sinus stenting in which retrograde three-dimensional rotational venography (3DRV) provided superior anatomical details of the venous sinuses for optimal sizing and positioning of stent. RESULTS: Comparison of pre stent 3DRV with post-stent contrast-enhanced flat panel detector CT allowed confirmation of stent placement and the result of stenosis dilation. CONCLUSION: This 3DRV technique provides precise visualization of venous sinus stenosis prior to stenting without the need for arterial cerebral angiography during the treatment course.

PMID- 29175829 TI - Safety and effectiveness of the Low Profile Visualized Intraluminal Support (LVIS and LVIS Jr) devices in the endovascular treatment of intracranial aneurysms: results of the TRAIL multicenter observational study. AB - BACKGROUND AND PURPOSE: To evaluate the safety and effectiveness of the low profile braided intracranial stents called the Low Profile Visualized Intraluminal Support (LVIS) devices for stent-assisted coil embolization of wide necked intracranial aneurysms. MATERIALS AND METHODS: This was a prospective, multicenter, observational study of unruptured and ruptured intracranial aneurysms treated with the LVIS devices. Imaging and clinical data were independently analyzed respectively by CoreLab and Clinical Event Committee. Primary endpoints were clinical safety, effectiveness, and angiographic stability of the results at 6 and 18 months. RESULTS: Ten centers participated in the study; 102 patients were included and 90 patients (42.2% men, 57.8% women) were eventually analyzed, among which 27 (30.0%) had multiple aneurysms. Twenty-three (25.6%) were ruptured aneurysms, four of which (4.4%) were treated in the acute phase. One aneurysm was treated per patient; 92 LVIS and LVIS Jr devices were placed overall. The total aneurysm occlusion rate was 91.0% on immediate post procedure angiograms, which remained unchanged at 6-month follow-up and was 92.4% at 18-month follow-up. One patient (1.1%) underwent retreatment between 6 and 18 months of follow-up. A modified Rankin score of 0 was documented for most cases immediately after the procedure (86.7%) and at 6-month (86.8%) and 18-month (83.3%) follow-up. The overall permanent morbidity rate at 18 months was 5.6% and the overall rate of events with sequelae related to the stent was 2.2%. The 18 month procedure-related mortality rate was 3.3%. No patient was deemed to require retreatment at 18-month follow-up. CONCLUSION: The LVIS/LVIS Jr endovascular devices are safe and effective in the treatment of ruptured and unruptured intracranial aneurysms, with acceptable complication rates, very high immediate total occlusion rates, and stable angiographic results. PMID- 29175831 TI - The fourth wave of biocatalysis is approaching. AB - Biocatalysis has undergone a tremendous development in the past few years. A plethora of methods enable the rather rapid tailored-design of an enzyme for a targeted reaction such as asymmetric synthesis of a chiral building block by the combination of information from sequence and structure databases with modern molecular biology methods and high-throughput screening tools. Moreover, novel non-natural reactions could be implemented into protein scaffolds and new enzyme classes are emerging, both broadening the repertoire of reactions now available for organic synthesis. Furthermore, impressive examples of metabolic engineering the combination of several newly introduced reaction steps in a microbial host have been developed, paving the way for large-scale processes for both pharmaceuticals and bulk chemicals. This contribution highlights recent developments in this area and points out future challenges.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'. PMID- 29175832 TI - Rear-facing versus forward-facing child restraints: an updated assessment. AB - OBJECTIVES: The National Highway Traffic Safety Administration and the American Academy of Pediatrics recommend children be placed in rear-facing child restraint systems (RFCRS) until at least age 2. These recommendations are based on laboratory biomechanical tests and field data analyses. Due to concerns raised by an independent researcher, we re-evaluated the field evidence in favour of RFCRS using the National Automotive Sampling System Crashworthiness Data System (NASS CDS) database. METHODS: Children aged 0 or 1 year old (0-23 months) riding in either rear-facing or forward-facing child restraint systems (FFCRS) were selected from the NASS-CDS database, and injury rates were compared by seat orientation using survey-weighted chi2 tests. In order to compare with previous work, we analysed NASS-CDS years 1988-2003, and then updated the analyses to include all available data using NASS-CDS years 1988-2015. RESULTS: Years 1988 2015 of NASS-CDS contained 1107 children aged 0 or 1 year old meeting inclusion criteria, with 47 of these children sustaining injuries with Injury Severity Score of at least 9. Both 0-year-old and 1-year-old children in RFCRS had lower rates of injury than children in FFCRS, but the available sample size was too small for reasonable statistical power or to allow meaningful regression controlling for covariates. CONCLUSIONS: Non-US field data and laboratory tests support the recommendation that children be kept in RFCRS for as long as possible, but the US NASS-CDS field data are too limited to serve as a strong statistical basis for these recommendations. PMID- 29175833 TI - Evaluation of an integrated multisector campaign to increase child helmet use in Vietnam. AB - OBJECTIVE: This study presents child helmet use before, during and after implementing the Vietnamese National Child Helmet Action Plan (NCHAP) and evaluates its effect on child helmet use. The NCHAP, an integrated multisector campaign, incorporated a wide-scale public awareness campaign, school-based interventions, increased police patrolling and enforcement, and capacity building and support to relevant government departments in target provinces. METHODS: In Vietnam's three largest cities, 100 schools in 20 districts were selected to monitor motorcycle helmet use behaviour. The effectiveness of the NCHAP was measured by unannounced, filmed observations of student motorcycle passengers and their adult drivers as they arrived or left their schools at four points. Baseline observations at each school were conducted in March 2014, with subsequent observations in April 2015, December 2015 and May 2016. RESULTS: Across the 84 218 observed students, student helmet prevalence increased from 36.1% in March 2014 to 69.3% immediately after the initiation in April 2015. Subsequent observations in December 2015 and May 2016 showed a reduction and stabilisation of helmet use, with 49.8% and 56.9% of students wearing helmets, respectively. Helmet use in students was higher when adult drivers were also wearing helmets. CONCLUSIONS: Integrated multisectoral interventions between governments, civil society and the corporate sector that incorporate communications, school-based education, incentives for change and police enforcement have the potential to increase helmet use among children. Future integrated campaigns may be more effective with an increased focus on parents and other adult drivers given their potential influence on child helmet use. PMID- 29175834 TI - Reactivity of CO2 on the surfaces of magnetite (Fe3O4), greigite (Fe3S4) and mackinawite (FeS). AB - The growing environmental, industrial and commercial interests in understanding the processes of carbon dioxide (CO2) capture and conversion have led us to simulate, by means of density functional theory calculations, the application of different iron oxide and sulfide minerals to capture, activate and catalytically dissociate this molecule. We have chosen the {001} and {111} surfaces of the spinel-structured magnetite (Fe3O4) and its isostructural sulfide counterpart greigite (Fe3S4), which are both materials with the Fe cations in the 2+/3+ mixed valence state, as well as mackinawite (tetragonal FeS), in which all iron ions are in the ferrous oxidation state. This selection of iron-bearing compounds provides us with understanding of the effect of the composition, stoichiometry, structure and oxidation state on the catalytic activation of CO2 The largest adsorption energies are released for the interaction with the Fe3O4 surfaces, which also corresponds to the biggest conformational changes of the CO2 molecule. Our results suggest that the Fe3S4 surfaces are unable to activate the CO2 molecule, while a major charge transfer takes place on FeS{111}, effectively activating the CO2 molecule. The thermodynamic and kinetic profiles for the catalytic dissociation of CO2 into CO and O show that this process is feasible only on the FeS{111} surface. The findings reported here show that these minerals show promise for future CO2 capture and conversion technologies, ensuring a sustainable future for society.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'. PMID- 29175835 TI - Paediatric ovarian tumours and their associated cancer susceptibility syndromes. AB - Non-epithelial ovarian tumours are rare neoplasms that occasionally arise in childhood and adolescence. They can be associated with various cancer susceptibility syndromes. The morphological overlap seen across these tumours and their rarity can make the diagnosis challenging. In the case of an incorrect diagnosis, the underlying genetic susceptibility may be missed. In this review, we outline the genetic background of ovarian non-epithelial tumours arising in children, emphasizing the genes harbouring pathogenic germline variants associated with each tumour type. Specifically, juvenile granulosa cell tumours, Sertoli-Leydig cell tumours, sex cord tumours with annular tubules, Sertoli cell tumours, germ cell tumours and small cell carcinoma of the ovary of hypercalcaemic type are discussed in this review. For each tumour type, we detail the personal and family history features and the presenting characteristics of the ovarian tumour as well as the pathological features and molecular markers that point towards a cancer predisposition syndrome. Throughout, we stress the need for specialised pathological review in difficult cases. PMID- 29175836 TI - Two patients with MIRAGE syndrome lacking haematological features: role of somatic second-site reversion SAMD9 mutations. AB - BACKGROUND: Myelodysplasia, infection, restriction of growth, adrenal hypoplasia, genital phenotypes and enteropathy (MIRAGE) syndrome is a recently described congenital disorder caused by heterozygous SAMD9 mutations. The phenotypic spectrum of the syndrome remains to be elucidated. METHODS AND RESULTS: We describe two unrelated patients who showed manifestations compatible with MIRAGE syndrome, with the exception of haematological features. Leucocyte genomic DNA samples were analysed with next-generation sequencing and Sanger sequencing, revealing the patients to have two de novoSAMD9 mutations on the same allele (patient 1 p.[Gln695*; Ala722Glu] and patient 2 p.[Gln39*; Asp769Gly]). In patient 1, p.Gln695* was absent in genomic DNA extracted from hair follicles, implying that the non-sense mutation was acquired somatically. In patient 2, with the 46,XX karyotype, skewed X chromosome inactivation pattern was found in leucocyte DNA, suggesting monoclonality of cells in the haematopoietic system. In vitro expression experiments confirmed the growth-restricting capacity of the two missense mutant SAMD9 proteins that is a characteristic of MIRAGE-associated SAMD9 mutations. CONCLUSIONS: Acquisition of a somatic nonsense SAMD9 mutation in the cells of the haematopoietic system might revert the cellular growth repression caused by the germline SAMD9 mutations (ie, second-site reversion mutations). Unexpected lack of haematological features in the two patients would be explained by the reversion mutations. PMID- 29175837 TI - Integrating protein engineering with process design for biocatalysis. AB - Biocatalysis uses enzymes for chemical synthesis and production, offering selective, safe and sustainable catalysis. While today the majority of applications are in the pharmaceutical sector, new opportunities are arising every day in other industry sectors, where production costs become a more important driver. In the early applications of the technology, it was necessary to design processes to match the properties of the biocatalyst. With the advent of protein engineering, organic chemists started to develop and improve enzymes to suit their needs. Likewise in industry, although not widespread, a new paradigm was already implemented several years ago to engineer enzymes to suit process needs. Today, a new era is entered, where the effectiveness with which such integrated protein and process engineering is achieved becomes critical to implementation. In this paper, the development of a tool to improve the effectiveness of this approach is discussed, namely the use of target-setting based on process requirements, to guide the necessary protein engineering.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'. PMID- 29175838 TI - Comparison of two low-sensitivity urine pregnancy tests for confirming the success of early medical abortion. AB - BACKGROUND: We introduced a single-window low-sensitivity urine pregnancy test (LSPT) to replace a double-window LSPT (both 1000 IU hCG) for self-assessment of the outcome of early medical abortion (EMA) (<=63 days gestation) 2 weeks later. We wished to compare assessment of outcomes of EMA with each LSPT. METHODS: A retrospective review of the outcomes of EMA during 10 months' use of the double window LSPT and the subsequent 10 months' use of the single-window LSPT to compare (i) detection of ongoing pregnancies and (ii) false-positive and invalid results with each LSPT. RESULTS: 492 and 555 women self-assessed the outcome of their EMA with the double- and single-window LSPTs, respectively. Ongoing pregnancies were uncommon and occurred in 4/1047 women (0.4%). Two of these four women did not conduct a LSPT as they presented before the LSPT was due with scant bleeding or continuing pregnancy symptoms. False-positive LSPT results occurred in 6 (1.2%) and 19 (3.4%) double- and single-window LSPT tests, respectively (P=0.0244). Invalid results were reported in 18 (3.6%) and 6 (1.1%) of double- and single-window LSPT groups, respectively (P=0.01). CONCLUSION: The introduction of the single-window LSPT has not impacted on the detection of ongoing pregnancy or on contact with the service due to a positive or invalid LSPT. Services could consider use of either LSPT but should also place emphasis on informing women about the clinical signs and symptoms that suggest failed abortion.

PMID- 29175841 TI - A randomised trial comparing pain and ease of use of two different stabilising forceps for insertion of intrauterine contraception. AB - BACKGROUND: Pain at intrauterine contraception (IUC) fitting may be a deterrent for women and any reduction in discomfort would be likely to be beneficial to both women and clinicians. AIM: This study investigated the associated pain and the ease of use of two different stabilising forceps at the time of IUC placement. DESIGN: Single-blinded randomised controlled trial. One hundred parous women aged 18-50 years who had undergone at least one vaginal delivery were recruited. SETTING: An integrated sexual health service in the North of England. METHODS: Women were randomised to the use of either a Littlewoods forceps or a single-toothed tenaculum forceps to stabilise the cervix at the time of IUC placement. Pain levels were measured at forceps application, IUC insertion, and 5 and 10 minutes post-procedure using a visual analogue scale (VAS). A clinician graded ease of use of the forceps and any associated bleeding. Wilcoxon rank-sum tests were used to compare pain levels between the two forceps groups. Linear regression was used when adjusting for potential confounders. RESULTS: Mean VAS scores were similar at forceps application (p=0.52), IUC fitting (p=0.10) and at 5 minutes (p=0.32). There was a statistical difference in the degree of pain experienced at 10 minutes in the tenaculum group (p=0.01). Physicians found both forceps easy to use and there was no difference in bleeding (p=0.49). CONCLUSIONS: Parous women who have had a vaginal delivery can be reassured that IUC fitting is well tolerated. Pain scores were not affected by the type of forceps used to stabilise the cervix at IUC placement. Both forceps investigated were easy to use. PMID- 29175843 TI - Diagnosing migraine. AB - Migraine is a common headache disorder, particularly in women. It usually starts during the teens and twenties, a time when many women are seeking contraception advice. Migraine without aura is the most prevalent type of migraine, affecting up to 70% of people with migraine, while the remainder experience attacks with and/or without aura. Aura is a phase of focal neurological symptoms, typically visual. An increasing body of evidence identifies aura as a marker of increased risk of ischaemic stroke and its presence is a contraindication to the use of combined hormonal contraception (CHC). However, aura is often confused with more generalised premonitory visual symptoms of migraine that may precede attacks of migraine with and without aura, which are not associated with stroke risk. Diagnostic confidence is needed so that CHC is not withheld unnecessarily. PMID- 29175844 TI - A very specific absence of focus? A patient's response to 'Diagnosing migraine'.

PMID- 29175850 TI - From word models to executable models of signaling networks using automated assembly. AB - Word models (natural language descriptions of molecular mechanisms) are a common currency in spoken and written communication in biomedicine but are of limited use in predicting the behavior of complex biological networks. We present an approach to building computational models directly from natural language using automated assembly. Molecular mechanisms described in simple English are read by natural language processing algorithms, converted into an intermediate representation, and assembled into executable or network models. We have implemented this approach in the Integrated Network and Dynamical Reasoning Assembler (INDRA), which draws on existing natural language processing systems as well as pathway information in Pathway Commons and other online resources. We demonstrate the use of INDRA and natural language to model three biological processes of increasing scope: (i) p53 dynamics in response to DNA damage, (ii) adaptive drug resistance in BRAF-V600E-mutant melanomas, and (iii) the RAS signaling pathway. The use of natural language makes the task of developing a model more efficient and it increases model transparency, thereby promoting collaboration with the broader biology community. PMID- 29175853 TI - Performance of statistical process control methods for regional surgical site infection surveillance: a 10-year multicentre pilot study. AB - BACKGROUND: Traditional strategies for surveillance of surgical site infections (SSI) have multiple limitations, including delayed and incomplete outbreak detection. Statistical process control (SPC) methods address these deficiencies by combining longitudinal analysis with graphical presentation of data. METHODS: We performed a pilot study within a large network of community hospitals to evaluate performance of SPC methods for detecting SSI outbreaks. We applied conventional Shewhart and exponentially weighted moving average (EWMA) SPC charts to 10 previously investigated SSI outbreaks that occurred from 2003 to 2013. We compared the results of SPC surveillance to the results of traditional SSI surveillance methods. Then, we analysed the performance of modified SPC charts constructed with different outbreak detection rules, EWMA smoothing factors and baseline SSI rate calculations. RESULTS: Conventional Shewhart and EWMA SPC charts both detected 8 of the 10 SSI outbreaks analysed, in each case prior to the date of traditional detection. Among detected outbreaks, conventional Shewhart chart detection occurred a median of 12 months prior to outbreak onset and 22 months prior to traditional detection. Conventional EWMA chart detection occurred a median of 7months prior to outbreak onset and 14 months prior to traditional detection. Modified Shewhart and EWMA charts additionally detected several outbreaks earlier than conventional SPC charts. Shewhart and SPC charts had low false-positive rates when used to analyse separate control hospital SSI data. CONCLUSIONS: Our findings illustrate the potential usefulness and feasibility of real-time SPC surveillance of SSI to rapidly identify outbreaks and improve patient safety. Further study is needed to optimise SPC chart selection and calculation, statistical outbreak detection rules and the process for reacting to signals of potential outbreaks. PMID- 29175854 TI - Transportation characteristics associated with non-arrivals to paediatric clinic appointments: a retrospective analysis of 51 580 scheduled visits. AB - BACKGROUND: Prior work has not studied the effects of transportation accessibility and patient factors on clinic non-arrival. OBJECTIVES: Our objectives were: (1) to evaluate transportation characteristics and patient factors associated with clinic non-arrival, (2) to evaluate the comparability of bus and car drive time estimates, and (3) to evaluate the combined effects of transportation accessibility and income on scheduled appointment non-arrival. METHODS: We queried electronic administrative records at an urban general pediatrics clinic. We compared patient and transportation characteristics between arrivals and non-arrivals for scheduled appointments using multivariable modeling. RESULTS: There were 15 346 (29.8%) clinic non-arrivals. In separate car and bus multivariable models that controlled for patient and transit characteristics, we identified significant interactions between income and drive time, and clinic non-arrival. Patients in the lowest quartile of income who were also in the longest quartile of travel time by bus had an increased OR of clinic non-arrival compared with patients in the lowest quartile of income and shortest quartile of travel time by bus (1.55; P<0.01). Similarly, patients in the lowest quartile of income who were also in the longest quartile of travel time by car had an increased OR of clinic non-arrival compared with patients in the lowest quartile of income and shortest quartile of travel time by car (1.21, respectively; P<0.01). CONCLUSIONS: Clinic non-arrival is associated with the interaction of longer travel time and lower income. PMID- 29175855 TI - Increasing the use of patient decision aids in orthopaedic care: results of a quality improvement project. AB - OBJECTIVE: To integrate patient decision aid (DA) delivery to promote shared decision-making and provide more patient-centred care within an orthopaedic surgery department for treatment of hip and knee osteoarthritis, lumbar herniated disc and lumbar spinal stenosis. METHODS: Different strategies were used across three distinct phases to promote DA delivery. First, we used a quality improvement bonus to generate awareness and interest in the DAs among specialists. Second, we adapted the electronic referral management system to enable DA orders at referral to a specialist. Third, we engaged clinic staff and specialists to design workflows that promoted DA delivery. We tracked the number of patients who received a DA, who ordered the DA, and collected usage data from a subset of patients. Our target was to reach 60% of patients with DAs. RESULTS: In phase 1, 28% (43/155) of spine patients and 37% (114/308) of hip/knee patients received a DA. In phase 2, 54% (64/118) of spine referrals and 58% (189/324) of hip/knee referrals included a request to send a patient a DA. In phase 3, 56% (90/162) of spine patients and 69% (213/307) of hip/knee patients received a DA, significantly more than in phase 1 (P<0.0001). In phase 3, both more DAs were ordered by clinic staff compared with specialists (56% phase 3 vs 34% phase 1, P<0.001) and sent before the visit (74% phase 3 vs 17% phase 1, P<0.001). Patients were more likely to report reviewing the DA when delivered before the visit (63% before vs 50% after, P=0.005). CONCLUSION: DA implementation into clinic workflow is possible and facilitated by engagement of the entire care team and the support of health information technology. PMID- 29175856 TI - Effect of a population-level performance dashboard intervention on maternal newborn outcomes: an interrupted time series study. AB - OBJECTIVES: To assess the effect of the Maternal Newborn Dashboard on six key clinical performance indicators in the province of Ontario, Canada. DESIGN: Interrupted time series using population-based data from the provincial birth registry covering a 3-year period before implementation of the Dashboard and 2.5 years after implementation (November 2009 through March 2015). SETTING: All hospitals in the province of Ontario providing maternal-newborn care (n=94). INTERVENTION: A hospital-based online audit and feedback programme. MAIN OUTCOME MEASURES: Rates of the six performance indicators included in the Dashboard. RESULTS: 2.5 years after implementation, the audit and feedback programme was associated with statistically significant absolute decreases in the rates of episiotomy (decrease of 1.5 per 100 women, 95% CI 0.64 to 2.39), induction for postdates in women who were less than 41 weeks at delivery (decrease of 11.7 per 100 women, 95% CI 7.4 to 16.0), repeat caesarean delivery in low-risk women performed before 39 weeks (decrease of 10.4 per 100 women, 95% CI 9.3 to 11.5) and an absolute increase in the rate of appropriately timed group B streptococcus screening (increase of 2.8 per 100, 95% CI 2.2 to 3.5). The audit and feedback programme did not significantly affect the rates of unsatisfactory newborn screening blood samples or formula supplementation at discharge. No statistically significant effects were observed for the two internal control outcomes or the four external control indicators-in fact, two external control indicators (episiotomy and postdates induction) worsened relative to before implementation. CONCLUSION: An electronic audit and feedback programme implemented in maternal newborn hospitals was associated with clinically relevant practice improvements at the provincial level in the majority of targeted indicators. PMID- 29175857 TI - Contextual interference during adaptation to asymmetric split-belt treadmill walking results in transfer of unique gait mechanics. AB - When humans make errors in stepping during walking due to a perturbation, they may adapt their gait as a way to correct for discrepancies between predicted and actual sensory feedback. This study sought to determine if increased contextual interference during acquisition of a novel asymmetric gait pattern would change lower-limb mechanical strategies generalized to different walking contexts. Such knowledge could help to clarify the role of contextual interference in locomotor adaptation, and demonstrate potential use in future gait rehabilitation paradigms. One belt on a split-belt treadmill was driven at a constant velocity while the other was driven at changing velocities according to one of three practice paradigms: serial, random blocked, or random training. Subjects returned to complete one of two different transfer tests. Results indicate that during acquisition, random practice requires unique gait mechanics to adapt to a challenging walking environment. Also, results from one transfer test close to that of the acquisition experience did not seem to demonstrate any contextual interference effect. Finally, random blocked practice resulted in highly unique changes in step length symmetry on a second, more challenging, transfer test. This perhaps indicates that a moderate level of contextual interference causes unique locomotor generalization strategies. PMID- 29175858 TI - Gelsolin regulates proliferation, apoptosis and invasion in natural killer/T-cell lymphoma cells. AB - The expression of gelsolin (GSN) is abnormal in many cancers, including extranodal nasal-type natural killer/T-cell lymphoma (NKTCL). However, the biological function of GSN and its mechanism in NKTCL remain unclear. We found that GSN overexpression significantly suppressed cell proliferation, colony formation and invasion, and promoted apoptosis of natural killer (NK) cell line YTS. Moreover, the upregulation of GSN significantly decreased the levels of PI3K and p-Akt. Interestingly, blocking the PI3K/Akt signaling pathway significantly inhibited cell proliferation and invasion and promoted apoptosis of YTS cells. In conclusion, our findings indicate that GSN can suppress cell proliferation and invasion and promote apoptosis of YTS cells, and the PI3K/Akt signaling pathway is likely to be involved in this process. PMID- 29175860 TI - High salinity conveys thermotolerance in the coral model Aiptasia. AB - The endosymbiosis between dinoflagellate algae of the genus Symbiodinium and stony corals provides the foundation of coral reef ecosystems. Coral bleaching, the expulsion of endosymbionts from the coral host tissue as a consequence of heat or light stress, poses a threat to reef ecosystem functioning on a global scale. Hence, a better understanding of the factors contributing to heat stress susceptibility and tolerance is needed. In this regard, some of the most thermotolerant corals live in particularly saline habitats, but possible effects of high salinity on thermotolerance in corals are anecdotal. Here we test the hypothesis that high salinity may lead to increased thermotolerance. We conducted a heat stress experiment at low, intermediate, and high salinities using a set of host-endosymbiont combinations of the coral model Aiptasia. As expected, all host endosymbiont combinations showed reduced photosynthetic efficiency and endosymbiont loss during heat stress, but the severity of bleaching was significantly reduced with increasing salinities for one of the host-endosymbiont combinations. Our results show that higher salinities can convey increased thermotolerance in Aiptasia, although this effect seems to be dependent on the particular host strain and/or associated symbiont type. This finding may help explain the extraordinarily high thermotolerance of corals in high salinity environments, such as the Red Sea and the Persian/Arabian Gulf, and provides novel insight regarding factors that contribute to thermotolerance. Since our results are based on a salinity effect in symbiotic sea anemones, it remains to be determined whether this salinity effect can also be observed in stony corals. PMID- 29175859 TI - Investigating trehalose synthesis genes after cold acclimation in the Antarctic nematode Panagrolaimus sp. DAW1. AB - Panagrolaimus sp. DAW1 is a freeze-tolerant Antarctic nematode which survives extensive intracellular ice formation. The molecular mechanisms of this extreme adaptation are still poorly understood. We recently showed that desiccation enhanced RNA interference (RNAi) soaking can be used in conjunction with quantitative polymerase chain reaction (qPCR) to screen for phenotypes associated with reduced expression of candidate genes in Panagrolaimus sp. DAW1. Here, we present the use of this approach to investigate the role of trehalose synthesis genes in this remarkable organism. Previous studies have shown that acclimating Panagrolaimus sp. DAW1 at 5 degrees C before freezing or desiccation substantially enhances survival. In this study, the expression of tps-2 and other genes associated with trehalose metabolism, as well as lea-1, hsp-70 and gpx-1, in cold-acclimated and non-acclimated nematodes was analyzed using qPCR. Pd-tps-2 and Pd-lea-1 were significantly upregulated after cold acclimation, indicating an inducible expression in the cold adaptation of Panagrolaimus sp. DAW1. The role of trehalose synthesis genes in Panagrolaimus sp. DAW1 was further investigated by RNAi. Compared to the controls, Pd-tps-2a(RNAi)-treated and cold-acclimated nematodes showed a significant decrease in mRNA, but no change in trehalose content or freezing survival. The involvement of two other trehalose synthesis genes (tps-2b and gob-1) was also investigated. These findings provide the first functional genomic investigation of trehalose synthesis genes in the non-model organism Panagrolaimus sp. DAW1. The presence of several trehalose synthesis genes with different RNAi sensitivities suggests the existence of multiple backup systems in Panagrolaimus sp. DAW1, underlining the importance of this sugar in preparation for freezing. PMID- 29175861 TI - NGF reprograms metastatic melanoma to a bipotent glial-melanocyte neural crest like precursor. AB - Melanoma pathogenesis from normal neural crest-derived melanocytes is often fatal due to aggressive cell invasion throughout the body. The identification of signals that reprogram de-differentiated, metastatic melanoma cells to a less aggressive and stable phenotype would provide a novel strategy to limit disease progression. In this study, we identify and test the function of developmental signals within the chick embryonic neural crest microenvironment to reprogram and sustain the transition of human metastatic melanoma to a neural crest cell-like phenotype. Results reveal that co-culture of the highly aggressive and metastatic human melanoma cell line C8161 upregulate a marker of melanosome formation (Mart 1) in the presence of embryonic day 3.5 chick trunk dorsal root ganglia. We identify nerve growth factor (NGF) as the signal within this tissue driving Mart 1 re-expression and show that NGF receptors trkA and p75 cooperate to induce Mart 1 re-expression. Furthermore, Mart-1 expressing C8161 cells acquire a gene signature of poorly aggressive C81-61 cells. These data suggest that targeting NGF signaling may yield a novel strategy to reprogram metastatic melanoma toward a benign cell type. PMID- 29175862 TI - Competitive pressures affect sexual signal complexity in Kurixalus odontotarsus: insights into the evolution of compound calls. AB - Male-male vocal competition in anuran species is critical for mating success; however, it is also energetically demanding and highly time-consuming. Thus, we hypothesized that males may change signal elaboration in response to competition in real time. Male serrate-legged small treefrogs (Kurixalus odontotarsus) produce compound calls that contain two kinds of notes, harmonic sounds called 'A notes' and short broadband sounds called 'B notes'. Using male evoked vocal response experiments, we found that competition influences the temporal structure and complexity of vocal signals produced by males. Males produce calls with a higher ratio of notes:call, and more compound calls including more A notes but fewer B notes with contest escalation. In doing so, males minimize the energy costs and maximize the benefits of competition when the level of competition is high. This means that the evolution of sexual signal complexity in frogs may be susceptible to selection for plasticity related to adjusting performance to the pressures of competition, and supports the idea that more complex social contexts can lead to greater vocal complexity.

PMID- 29175864 TI - Investigating associations between the built environment and physical activity among older people in 20 UK towns. AB - BACKGROUND: Policy initiatives such as WHO Age Friendly Cities recognise the importance of the urban environment for improving health of older people, who have both low physical activity (PA) levels and greater dependence on local neighbourhoods. Previous research in this age group is limited and rarely uses objective measures of either PA or the environment. METHODS: We investigated the association between objectively measured PA (Actigraph GT3x accelerometers) and multiple dimensions of the built environment, using a cross-sectional multilevel linear regression analysis. Exposures were captured by a novel foot-based audit tool that recorded fine-detail neighbourhood features relevant to PA in older adults, and routine data. RESULTS: 795 men and 638 women aged 69-92 years from two national cohorts, covering 20 British towns, were included in the analysis. Median time in moderate to vigorous PA (MVPA) was 27.9 (lower quartile: 13.8, upper quartile: 50.4) minutes per day. There was little evidence of associations between any of the physical environmental domains (eg, road and path quality defined by latent class analysis; number of bus stops; area aesthetics; density of shops and services; amount of green space) and MVPA. However, analysis of area level income deprivation suggests that the social environment may be associated with PA in this age group. CONCLUSIONS: Although small effect sizes cannot be discounted, this study suggests that older individuals are less affected by their local physical environment and more by social environmental factors, reflecting both the functional heterogeneity of this age group and the varying nature of their activity spaces. PMID- 29175865 TI - Longitudinal analysis of cardiovascular disease risk profile in neighbourhood poverty subgroups: 5-year results from an afterschool fitness programme in the USA. AB - BACKGROUND: The WHO calls for affordable population-based prevention strategies for reducing the global burden of cardiovascular disease (CVD) on morbidity and mortality; however, effective, sustainable and accessible community-based approaches for CVD prevention in at-risk youth have yet to be identified. We examined the effects of implementing a daily park-based afterschool fitness programme on youth CVD risk profiles over 5 years and across area poverty subgroups. METHODS: The study included 2264 youth (mean age 9.4 years, 54% male, 50% Hispanic, 47% non-Hispanic black, 70% high/very high area poverty) in Miami, Florida, USA. We used three-level repeated measures mixed models to determine the longitudinal effects of programme participation on modifiable CVD outcomes (2010 2016). RESULTS: Duration of programme participation was significantly associated with CVD risk profile improvements, including body mass index (BMI) z-score, diastolic/systolic blood pressure, skinfold thicknesses, waist-hip ratio, sit ups, push-ups, Progressive Aerobic Cardiovascular Endurance Run (PACER) score, 400 m run time, probability of developing systolic/diastolic hypertension and overweight/obesity in high/very high poverty neighbourhoods (P<0.001). Diastolic blood pressure decreased 3.4 percentile points (95% CI -5.85 to -0.85), 8.1 percentile points (95% CI -11.98 to -4.26), 6.1 percentile points (95% CI -11.49 to -0.66), 7.6 percentile points (95% CI -15.33 to -0.15) and 11.4 percentile points (95% CI -25.32 to 2.61) for 1-5 years, respectively, in high/very high poverty areas. In contrast, significant improvements were found only for PACER score and waist-hip ratio in low/mid poverty areas. CONCLUSION: This analysis presents compelling evidence demonstrating that park-based afterschool programmes can successfully maintain or improve at-risk youth CVD profiles over multiple years.

AB - BACKGROUND: Undiagnosed HIV infections could undermine efforts to reverse the global AIDS epidemic by 2030. In this study, we estimated the percentage of HIV positive persons who remain undiagnosed within a hyperendemic South African community. METHODS: The data come from a population-based surveillance system located in the Umkhanyakude district of the northern KwaZulu-Natal province, South Africa. We annually tested 38 661 adults for HIV between 2005 and 2016. Using the HIV-positive test results of 12 039 (31%) participants, we then back calculated the incidence of infection and derived the number of undiagnosed cases from this result. RESULTS: The percentage of undiagnosed HIV cases decreased from 29.3% in 2005 to 15.8% in 2011. During this period, however, approximately 50% of the participants refused to test for HIV, which lengthened the average time from infection to diagnosis. Consequently, the percentage of undiagnosed HIV cases reversed direction and steadily increased from 16.1% to 18.9% over the 2012-2016 period. CONCLUSIONS: Results from this hyperendemic South African setting show that the HIV testing rate is low, with long infection times, and an unsatisfactorily high percentage of undiagnosed cases. A high level of repeat HIV testing is needed to minimise the time from infection to diagnosis if the global AIDS epidemic is to be reversed within the next two decades. PMID- 29175869 TI - Metal-promoted titania photocatalysis for destruction of nitrates and organics from aqueous environments. AB - This review article provides an overview of activities in the rapidly developing field of water purification via photocatalytic methods and focuses on the removal of nitrate ions with simultaneous removal of the hole scavenger. Many of the issues associated with provision of potable water in the developing world may be resolved by the use of simple physical methodologies such as filtration. However, many of the issues associated with water purity in the developed world involve complex, stable molecules present at low concentrations that are nonetheless capable of producing toxic effects in plants and animals and that require more demanding removal technologies. Photocatalytic methods can be operated remotely and often show minimal production of undesired side products. Titania alone shows limitations, not only in terms of the slow rate of photoreduction of nitrate but also in terms of selectivity and the need to employ radiation in the UV region due to the magnitude of the band gap. Key challenges may be defined as: reducing the band gap/increasing absorption in the visible region, enhancing the adsorption capacity/access to the surface sites and reducing the rate of hole/electron recombination. The present article will focus on the use of titania based materials that involve metal co-catalysts for nitrate reduction.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'. PMID- 29175868 TI - Do socioeconomic inequalities in pain, psychological distress and oral health increase or decrease over the life course? Evidence from Sweden over 43 years of follow-up. AB - BACKGROUND: Inequalities over the life course may increase due to accumulation of disadvantage or may decrease because ageing can work as a leveller. We report how absolute and relative socioeconomic inequalities in musculoskeletal pain, oral health and psychological distress evolve with ageing. METHODS: Data were combined from two nationally representative Swedish panel studies: the Swedish Level-of Living Survey and the Swedish Panel Study of Living Conditions of the Oldest Old. Individuals were followed up to 43 years in six waves (1968, 1974, 1981, 1991/1992, 2000/2002, 2010/2011) from five cohorts: 1906-1915 (n=899), 1925-1934 (n=906), 1944-1953 (n=1154), 1957-1966 (n=923) and 1970-1981 (n=1199). The participants were 15-62 years at baseline. Three self-reported outcomes were measured as dichotomous variables: teeth not in good conditions, psychological distress and musculoskeletal pain. The fixed-income groups were: (A) never poor and (B) poor at least once in life. The relationship between ageing and the outcomes was smoothed with locally weighted ordinary least squares, and the relative and absolute gaps were calculated with Poisson regression using generalised estimating equations. RESULTS: All outcomes were associated with ageing, birth cohort, sex and being poor at least once in live. Absolute inequalities increased up to the age of 45-64 years, and then they decreased. Relative inequalities were large already in individuals aged 15-25 years, showing a declining trend over the life course. Selective mortality did not change the results. The socioeconomic gap was larger for current poverty than for being poor at least once in life. CONCLUSION: Inequalities persist into very old age, though they are more salient in midlife for all three outcomes observed. PMID- 29175870 TI - Non-thermal-plasma-activated de-NOx catalysis. AB - The combination of non-thermal plasma (NTP) with catalyst systems as an alternative technology to remove NOx emissions in the exhaust of lean-burn stationary and mobile sources is reviewed. Several factors, such as low exhaust gas temperatures (below 300 degrees C), low selectivity to N2 and the presence of impurities, make current thermally activated technologies inefficient. Various hybrid plasma-catalyst systems have been examined and shown to have a synergistic effect on de-NOx efficiency when compared with NTP or catalyst-alone systems. The NTP is believed to form oxygenated species, such as aldehydes and nitrogen containing organic species, and to convert NO to NO2, which improves the reduction efficiency of N2 during hydrocarbon-selective catalytic reduction reactions. The NTP has been used as a pretreatment to convert NO to its higher oxidation states such as NO2 to improve NOx reduction efficiency in the subsequent processes, e.g. NH3-selective catalytic reduction. It has been applied to the lean phase of the NOx storage to improve the adsorption capacity of the catalyst by conversion of NO to NO2 Alternatively, a catalyst with high adsorption capacity is chosen and the NTP is applied to the rich phase to improve the reduction activity of the catalyst at low temperature.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'. PMID- 29175871 TI - Structure and function of RET in multiple endocrine neoplasia type 2. AB - It has been twenty-five years since the discovery of oncogenic germline RET mutations as the cause of multiple endocrine neoplasia type 2 (MEN2). Intensive work over the last two and a half decades on RET genetics, signaling and cell biology has provided the current bases for the genotype-phenotype and functional correlations within this cancer syndrome. On the contrary, the structural and molecular basis for RET tyrosine kinase domain activation and oncogenic deregulation has remained largely elusive. Recent studies with a strong crystallographic and biochemical focus have started to elucidate key insights into such molecular and atomic details revealing unexpected and private mechanisms of actions and molecular determinants not previously envisioned. This review focuses on the structure and function of the RET receptor, and in particular, on what a more detailed view of the protein itself and what the current structural and molecular information tell us about the genotype and phenotype relationships in the cancer syndrome MEN2. PMID- 29175872 TI - Notch pathway inhibition targets chemoresistant insulinoma cancer stem cells. AB - Insulinomas (INS) are the most common neuroendocrine pancreatic tumours in humans and dogs. The long-term prognosis for malignant INS is still poor due to a low success rate of the current treatment modalities, particularly chemotherapy. A better understanding of the molecular processes underlying the development and progression of INS is required to develop novel targeted therapies. Cancer stem cells (CSCs) are thought to be critical for the engraftment and chemoresistance of many tumours, including INS. This study was aimed to characterise and target INS CSCs in order to develop novel targeted therapies. Highly invasive and tumourigenic human and canine INS CSC-like cells were successfully isolated. These cells expressed stem cell markers (OCT4, SOX9, SOX2, CD133 and CD34), exhibited greater resistance to 5-fluorouracil (5-FU) and demonstrated a more invasive and tumourigenic phenotype in vivo compared to bulk INS cells. Here, we demonstrated that Notch-signalling-related genes (NOTCH2 and HES1) were overexpressed in INS CSC-like cells. Protein analysis showed an active NOTCH2 HES1 signalling in INS cell lines, especially in cells resistant to 5-FU. Inhibition of the Notch pathway, using a gamma secretase inhibitor (GSI), enhanced the sensitivity of INS CSC-like cells to 5-FU. When used in combination GSI and 5-FU, the clonogenicity in vitro and the tumourigenicity in vivo of INS CSC-like cells were significantly reduced. These findings suggested that the combined strategy of Notch signalling inhibition and 5-FU synergistically attenuated enriched INS CSC populations, providing a rationale for future therapeutic exploitation. PMID- 29175873 TI - Crowned dens syndrome. AB - Crowned dens syndrome is a rare presentation of calcium pyrophosphate deposition disease. It is characterised by severe occipital pain and neck stiffness. Acute presentations are typically accompanied by fever and an inflammatory response and hence can be misdiagnosed as polymyalgia rheumatica or meningitis. Chronic relapsing presentations may be misdiagnosed as cervicogenic neck pain or occipital neuralgia. We present a patient who presented with a chronic relapsing form of crowned dens syndrome and discuss the epidemiology, typical presentation and management of this eminently treatable condition. PMID- 29175874 TI - Psychiatric disease in an adolescent as a harbinger of cerebral X-linked adrenoleukodystrophy. AB - X-linked adrenoleukodystrophy (XALD) typically presents as a childhood cerebral demyelinating form, as an adult-onset adrenomyeloneuropathy or as adrenocortical insufficiency. Cerebral demyelination presenting in adolescence is unusual. We present an 17-year-old boy with adolescent-onset XALD initially manifesting with slowly progressive psychiatric symptoms. He was initially diagnosed with attention-deficit hyperactivity disorder and an acute psychosis. However, he was ultimately diagnosed with XALD based on his clinical course, neuroimaging findings and biochemical abnormalities. This case reiterates the atypical presentations of adolescent-onset cerebral XALD that may go unrecognised and misdiagnosed as a neurodevelopmental or psychiatric disease. Treatments for cerebral ALD are potentially life-saving, particularly when given early in the disease course.

PMID- 29175878 TI - Ionised calcium levels in major trauma patients who received blood en route to a military medical treatment facility. AB - BACKGROUND: Hypocalcaemia is a common metabolic derangement in critically ill patients. Blood transfusion can also contribute to depleted calcium levels. The aims of this study were to identify the incidence of hypocalcaemia in military trauma patients receiving blood products en route to a deployed hospital facility and to determine if intravenous calcium, given during the prehospital phase, has an effect on admission calcium levels. METHODS: This was a retrospective review of patients transported by the UK Medical Emergency Response Team in Afghanistan between January 2010 and December 2014 who were treated with blood products in the prehospital setting. Total units of blood products administered, basic demographics, Injury Severity Score and trauma type were collected. Ionised serum calcium levels on admission to hospital were compared between those who received blood products without prehospital intravenous calcium supplemental therapy (non treatment) and patients who were treated with 10 mL of intravenous calcium chloride (10%) concurrently with blood products (treatment). RESULTS: The study included 297 patients; 237 did not receive calcium and 60 did. The incidence of hypocalcaemia in the non-treatment group was 70.0% (n=166) compared with 28.3% (n=17) in the treatment group. Serum calcium levels were significantly different between the groups (1.03 mmol/L vs 1.25 mmol/L, difference 0.22 mmol/L, 95% CI 0.15 to 0.27). In the non-treatment group, 26.6% (n=63) had calcium levels within the normal range compared with 41.7% (n=25) in those who received calcium. There was a dose response of calcium level to blood products with a significant decrease in calcium levels as the volume of blood products increased. CONCLUSION: Trauma patients who received blood products were at high risk of hypocalcaemia. Aggressive management of these patients with intravenous calcium during transfusion may be required.

AB - BACKGROUND: Return ED visits are frequent and may be due to adverse events: adverse outcomes related to healthcare received. An interactive voice response system (IVRS) is a technology that translates human telephone input into digital data. Use of IVRS has been explored in many healthcare settings but to a limited extent in the ED. We determined the feasibility of using an IVRS to assess for adverse events after ED discharge. METHODS: This before and after study assessed detection of adverse events among consecutive high-acuity patients discharged from a tertiary care ED pre-IVRS and post-IVRS over two 2-week periods. The IVRS asked if the patient was having a health problem and if they wanted to speak to a nurse. Patients responding yes received a telephone interview. We searched health records for deaths, admissions to hospital and return ED visits. Three trained emergency physicians independently determined adverse event occurrence. We analysed the data using descriptive statistics. RESULTS: Of 968 patients studied, patients' age, sex, acuity and presenting complaint were comparable pre-IVRS and post-IVRS. Postimplementation, 393 (81.7%) of 481 patients had successful IVRS contact. Of these, 89 (22.6%) wanted to speak to a nurse. A total of 37 adverse events were detected over the two periods: 10 patients with 10 (6.5%) adverse events pre-IVRS and 16 patients with 27 (16.9%) adverse events post-IVRS. In the postimplementation period, the adverse events of seven patients were detected by the IVRS and five patients spontaneously requested assistance navigating post-ED care. CONCLUSIONS: This was a successful proof-of-concept study for applying IVRS technology to assess patient safety issues for discharged high-acuity ED patients.

AB - This paper reports on a qualitative evaluation of a Norfolk-based network of community singing workshops aimed at people with mental health conditions and the general public. The aims of the study were (a) to evaluate the effectiveness of the Sing Your Heart Out (SYHO) project and (b) to identify the key features which made the project distinctive. The study draws on 20 interviews with participants, two focus groups with organisers and workshop leaders, and participative observation over a 6-month period. Interviewees all reported improvement in or maintenance of their mental health and well-being as a direct result of engagement in the singing workshops. For most it was a key component, and for some the only and sufficient component in their recovery and ongoing psychological stability. SYHO was regarded as different from choirs and from most other social groups and also different from therapy groups, music or otherwise. The combination of singing with an inclusive social aspect was regarded as essential in effecting recovery. The lack of pressure to discuss their condition and the absence of explicit therapy was also mentioned by most participants as an important and welcome element in why SYHO worked for them. The combination of singing and social engagement produced an ongoing feeling of belonging and well being. Attendance provided them with structure, support and contact that improved functioning and mood. We conclude that the SYHO model offers a low-commitment, low-cost tool for mental health recovery within the community. PMID- 29175882 TI - Evidence and speculation: reimagining approaches to architecture and research within the paediatric hospital. AB - As the dominant research paradigm within the construction of contemporary healthcare facilities, evidence-based design (EBD) will increasingly impact our expectations of what hospital architecture should be. Research methods within EBD focus on prototyping incremental advances and evaluating what has already been built. Yet medical care is a rapidly evolving system; changes to technology, workforce composition, patient demographics and funding models can create rapid and unpredictable changes to medical practice and modes of care. This dynamism has the potential to curtail or negate the usefulness of current best practice approaches. To imagine new directions for the role of the hospital in society, or innovative ways in which the built environment might support well-being, requires a model that can project beyond existing constraints. Speculative design employs a design-based research methodology to imagine alternative futures and uses the artefacts created through this process to enable broader critical reflection on existing practices. This paper examines the contribution of speculative design within the context of the paediatric hospital as a means of facilitating critical reflection regarding the design of new healthcare facilities. While EBD is largely limited by what has already been built, speculative design offers a complementary research method to meet this limitation.

AB - OBJECTIVES: To explore smoking prevalence and attitudes towards smoking among Estonian physicians in 2002 and 2014. DESIGN: Two self-administered cross sectional postal surveys were conducted among practising physicians in Estonia. PARTICIPANTS: Initial sample consisted of all practising physicians in Estonia. The corrected response rate was 67.8% in 2002 and 53.1% in 2014. Present study sample was restricted to physicians younger than 65 years (n=2549 in 2002, n=2339 in 2014). METHODS: Age-standardised prevalence of smoking and prevalence of agreement with seven statements concerning attitudes towards smoking was determined. To analyse association of physicians' attitudes towards smoking with study year and smoking status, logistic regression analysis was used. Adjusted ORs of agreement with the seven statements were determined. Corresponding 95% CIs were calculated. RESULTS: The age-standardised prevalence of current smoking among men was 26.8% in 2002 and 15.3% in 2014, among women 10.4% and 5.8%, respectively. Compared with the year 2002, in 2014, prevalence of agreement with statements declaring harmfulness of smoking was higher and prevalence of agreement with statements approving smoking was lower. Adjusted ORs showed that compared with 2002, physicians' attitudes towards smoking were less favourable in 2014, and physicians' attitudes towards smoking were associated with their smoking status. CONCLUSIONS: Compared with 2002, the age-standardised smoking prevalence among male and female physicians was lower, and attitudes towards smoking were less approving in 2014. The smoking physicians had more approving attitudes towards smoking than their non-smoking colleagues.

AB - INTRODUCTION: Globally, overweight and obesity were estimated to cause 3.4 million deaths, 3.9% of years of life lost and 3.8% of disability-adjusted life years in 2010. Despite the fact that obesity and overweight is a problem of high income countries, low- and middle-income countries (LMICs), in particular urban settings of sub-Saharan African countries, face the challenge of an increasing trend. The aim of this systematic review and meta-analysis will be to determine the prevalence of obesity and overweight individuals in sub-Saharan Africa and to help guide policy planners in the decision-making process for the increase in non communicable diseases in Africa. METHODS AND ANALYSES: A comprehensive systematic review and meta-analysis of published studies on the prevalence of obesity and overweight in sub-Saharan Africa will be conducted. A computerised internet search using Medline/PubMed, Google Scholar and EMBASE databases and reference lists of previous prevalence studies and detailed search strategy and cross checking of reference lists of published peer-reviewed articles will be conducted to identify all epidemiological and/or clinical studies published in English and French. We will use the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) statement for reporting. The overall effect (pooled estimated effect size) of the prevalence of obesity and overweight will be analysed using the Der Simonian-Laird random effects meta-analysis (random effects model) and the obesity proportion (with 95% CI) will be measured. ETHICS AND DISSEMINATION: The underlying work is based on systematic reviews of published data and thus doed not require ethical review approval. The findings of the systematic review will be disseminated in different conferences and seminars and will be published in a reputable and refereed international peer-reviewed journal.

PMID- 29175885 TI - How effective is community physical activity promotion in areas of deprivation for inactive adults with cardiovascular disease risk and/or mental health concerns? Study protocol for a pragmatic observational evaluation of the 'Active Herts' physical activity programme. AB - INTRODUCTION: There is a high prevalence of inactive adults in the UK, and many suffer from conditions such as cardiovascular disease (CVD) or poor mental health. These coexist more frequently in areas of higher socioeconomic deprivation. There is a need to test the effectiveness, acceptability and sustainability of physical activity programmes. Active Herts uses novel evidence based behaviour change techniques to target physical inactivity. METHODS AND ANALYSIS: Active Herts is a community physical activity programme for inactive adults aged 16+ with one or more risk factors for CVD and/or a mild to moderate mental health condition. This evaluation will follow a mixed-methods longitudinal (baseline, and 3-month, 6-month and 12-month follow-ups) design. Pragmatic considerations mean delivery of the programme differs by locality. In two areas programme users will receive a behaviour change technique booklet, regular consultations, a booster phone call, motivational text messages and signposting to 12 weeks of exercise classes. In another two areas programme users will also receive 12 weeks of free tailored exercise classes, with optional exercise 'buddies' available. An outcome evaluation will assess changes in physical activity as the primary outcome, and sporting participation, sitting, well-being, psychological capability and reflective motivation as secondary outcomes. A process evaluation will explore the views of stakeholders, delivery staff and programme leads. Economic evaluation will examine the programme costs against the benefits gained in terms of reduced risk of morbidity. ETHICS AND DISSEMINATION: This study was been approved by the Faculty of Medicine and Health Sciences Research Ethics Committee at the University of East Anglia. Informed written consent will be obtained from programme users in the evaluation. Results will be published in peer-reviewed journals, presented at conferences, and shared through the study website and local community outlets.

PMID- 29175886 TI - Monitoring of clinical strains and environmental fungal aerocontamination to prevent invasive aspergillosis infections in hospital during large deconstruction work: a protocol study. AB - INTRODUCTION: Monitoring fungal aerocontamination is an essential measure to prevent severe invasive aspergillosis (IA) infections in hospitals. One central block among 32 blocks of Edouard Herriot Hospital (EHH) was entirely demolished in 2015, while care activities continued in surrounding blocks. The main objective was to undertake broad environmental monitoring and clinical surveillance of IA cases to document fungal dispersion during major deconstruction work and to assess clinical risk. METHODS AND ANALYSIS: A daily environmental survey of fungal loads was conducted in eight wards located near the demolition site. Air was collected inside and outside selected wards by agar impact samplers. Daily spore concentrations were monitored continuously by volumetric samplers at a flow rate of 10 L.min-1. Daily temperature, wind direction and speed as well as relative humidity were recorded by the French meteorological station Meteociel. Aspergillus fumigatus strains stored will be genotyped by multiple-locus, variable-number, tandem-repeat analysis. Antifungal susceptibility will be assessed by E-test strips on Roswell Park Memorial Institute medium supplemented with agar. Ascertaining the adequacy of current environmental monitoring techniques in hospital is of growing importance, considering the rising impact of fungal infections and of curative antifungal costs. The present study could improve the daily management of IA risk during major deconstruction work and generate new data to ameliorate and redefine current guidelines. ETHICS AND DISSEMINATION: This study was approved by the clinical research and ethics committees of EHH. PMID- 29175887 TI - Impact of US smoke-free air laws on restaurants and bars by employer size: a panel study. AB - OBJECTIVES: Thirty states have smoke-free air laws that ban smoking in restaurants and bars, covering nearly two-thirds of the US population. It is well established that these laws generally have a null or positive economic impact on restaurants and bars. However, all establishments in a geographic area are usually treated as a homogeneous group without considering the potential for differential effects by establishment characteristics. This study uses variation in smoke-free air laws over time to estimate their impact on employment in restaurants and bars with a focus on potential differences by employer size (number of employees). A two-pronged approach with a national-level and state level analysis is used to take advantage of more granular data availability for a single state (North Carolina). DESIGN: Observational study using panel data. SETTING: 1) US, 2) North Carolina INTERVENTIONS: Smoke-free air laws. OUTCOME MEASURES: State-level accommodation and food services employment for all 50 states and District of Columbia from 1990 through 2014 (Quarterly Census of Employment and Wages); county-level restaurant and bar employment in North Carolina from 2001 through 2014 (North Carolina Department of Commerce). RESULTS: There is no evidence of a redistributive effect of smoke-free air laws on restaurant and bar employment by employer size. CONCLUSION: The lack of a redistributive effect is an important finding for policy-makers considering implementation or expansion of a smoke-free air law to protect employees and patrons from the dangers of exposure to secondhand smoke. PMID- 29175888 TI - When has service provision for transient ischaemic attack improved enough? A discrete event simulation economic modelling study. AB - OBJECTIVES: The aim of this study was to examine the impact of transient ischaemic attack (TIA) service modification in two hospitals on costs and clinical outcomes. DESIGN: Discrete event simulation model using data from routine electronic health records from 2011. PARTICIPANTS: Patients with suspected TIA were followed from symptom onset to presentation, referral to specialist clinics, treatment and subsequent stroke. INTERVENTIONS: Included existing versus previous (less same day clinics) and hypothetical service reconfiguration (7-day service with less availability of clinics per day). OUTCOME MEASURES: The primary outcome of the model was the prevalence of major stroke after TIA. Secondary outcomes included service costs (including those of treating subsequent stroke) and time to treatment and attainment of national targets for service provision (proportion of high-risk patients (according to ABCD2 score) seen within 24 hours). RESULTS: The estimated costs of previous service provision for 490 patients (aged 74+/-12 years, 48.9% female and 23.6% high risk) per year at each site were L340 000 and L368 000, respectively. This resulted in 31% of high-risk patients seen within 24 hours of referral (47/150) with a median time from referral to clinic attendance/treatment of 1.15 days (IQR 0.93-2.88). The costs associated with the existing and hypothetical services decreased by L5000 at one site and increased L21 000 at the other site. Target attainment was improved to 79% (118/150). However, the median time to clinic attendance was only reduced to 0.85 days (IQR 0.17-0.99) and thus no appreciable impact on the modelled incidence of major stroke was observed (10.7 per year, 99% CI 10.5 to 10.9 (previous service) vs 10.6 per year, 99% CI 10.4 to 10.8 (existing service)). CONCLUSIONS: Reconfiguration of services for TIA is effective at increasing target attainment, but in services which are already working efficiently (treating patients within 1-2 days), it has little estimated impact on clinical outcomes and increased investment may not be worthwhile.

AB - OBJECTIVES: To identify the approaches that are used in improving on male partner involvement in the prevention of mother-to-child transmission (PMTCT) of HIV and their impact on the uptake maternal antiretroviral therapy (ART) in sub-Saharan Africa (SSA). SETTING: This was a systematic review and meta-analysis of published studies carried out in SSA at all levels of healthcare (primary, secondary, tertiary and community). PARTICIPANTS: The participants of the studies included were HIV-positive pregnant women and breastfeeding mothers with their male partners. Studies were included if they were conducted in SSA and mentioned an approach used in improving male partner involvement with data on the impact on the uptake of maternal ART uptake. OUTCOMES: In the protocol, maternal ART uptake, infant prophylaxis, safe infant feeding options, condom use and family planning were envisaged. However, only maternal ART has been reported here due to limitations on the word count. RESULTS: From an initial 2316 non-duplicate articles, 17 articles were included in the systematic review and meta-analysis. In the combined model, the ORs for complex community interventions, enhanced psychosocial interventions, verbal encouragement and invitation letters were 4.22 (95% CI 2.27 to 7.77), 2.29 (95% CI 1.42 to 7.69), 2.39 (95% CI 1.26 to 4.53) and 1.21 (95% CI 0.89 to 1.63), respectively, whereas in the model using adjusted ORs, enhanced psychosocial interventions had a higher effect than any other intervention. The heterogeneity was moderate using adjusted ORs. CONCLUSION: Enhanced psychosocial interventions and complex community interventions increase male partner involvement and the uptake of PMTCT services more than any other intervention. Invitation letters had no effect. More randomised trials and observational studies (that have adjusted for potential confounders) are needed in the future. PROSPERO REGISTRATION NUMBER: 42016032673. PMID- 29175890 TI - Is there an association between vitamin D status and risk of chronic low back pain? A nested case-control analysis in the Nord-Trondelag Health Study. AB - OBJECTIVES: To explore potential associations between vitamin D status and risk of chronic low back pain (LBP) in a Norwegian cohort, and to investigate whether relationships depend on the season of blood sample collection. DESIGN: A nested case-control study in a prospective data set. SETTING: The Norwegian community based Nord-Trondelag Health Study (HUNT). Data were collected in the HUNT2 (1995 1997) and HUNT3 (2006-2008) surveys. MAIN OUTCOME MEASURE: Chronic LBP, defined as LBP persisting at least 3 months continuously during the past year. PARTICIPANTS: Among individuals aged 19-55 years without LBP in HUNT2, a data set was generated including 1685 cases with LBP in HUNT3 and 3137 controls without LBP. METHODS: Blood samples from the participants collected in HUNT2 were analysed for serum 25-hydroxyvitamin D (25(OH)D) level. Associations with LBP in HUNT3 were evaluated by unconditional logistic regression analysis with adjustment for age, sex, work status, physical activity at work and in leisure time, education, smoking, and body mass index. RESULTS: No association between vitamin D status and risk of chronic LBP was found in the total data set (OR per 10 nmol/L 25(OH)D=1.01, 95% CI 0.97 to 1.06) or in individuals with blood samples collected in summer/autumn (OR per 10 nmol/L 25(OH)D=0.99, 95% CI 0.93 to 1.06). For blood samples drawn in winter/spring, associations differed significantly between women and men (p=0.004). Among women a positive association was seen (OR per 10 nmol/L 25(OH)D=1.11, 95% CI 1.02 to 1.20), but among men no significant association was observed (OR per 10 nmol/L 25(OH)D=0.90, 95% CI 0.81 to 1.01). CONCLUSIONS: Overall, no association between vitamin D status and risk of LBP was demonstrated. The association suggested in women for the winter/spring season cannot be regarded as established. PMID- 29175891 TI - Self-management of cardiac pain in women: an evidence map. AB - OBJECTIVE: To describe the current evidence related to the self-management of cardiac pain in women using the process and methodology of evidence mapping. DESIGN AND SETTING: Literature search for studies that describe the self management of cardiac pain in women greater than 18 years of age, managed in community, primary care or outpatient settings, published in English or a Scandinavian language between 1 January 1990 and 24 June 2016 using AMED, CINAHL, ERIC, EMBASE, MEDLINE, Proquest, PsychInfo, the Cochrane Library, Scopus, Swemed+, Web of Science, the Clinical Trials Registry, International Register of Controlled Trials, MetaRegister of Controlled Trials, theses and dissertations, published conference abstracts and relevant websites using GreyNet International, ISI proceedings, BIOSIS and Conference papers index. Two independent reviewers screened using predefined eligibility criteria. Included articles were classified according to study design, pain category, publication year, sample size, per cent women and mean age. INTERVENTIONS: Self-management interventions for cardiac pain or non-intervention studies that described views and perspectives of women who self-managed cardiac pain. PRIMARY AND SECONDARY OUTCOMES MEASURES: Outcomes included those related to knowledge, self-efficacy, function and health-related quality of life. RESULTS: The literature search identified 5940 unique articles, of which 220 were included in the evidence map. Only 22% (n=49) were intervention studies. Sixty-nine per cent (n=151) of the studies described cardiac pain related to obstructive coronary artery disease (CAD), 2% (n=5) non-obstructive CAD and 15% (n=34) postpercutaneous coronary intervention/cardiac surgery. Most were published after 2000, the median sample size was 90 with 25%-100% women and the mean age was 63 years. CONCLUSIONS: Our evidence map suggests that while much is known about the differing presentations of obstructive cardiac pain in middle aged women, little research focused on young and old women, non-obstructive cardiac pain or self-management interventions to assist women to manage cardiac pain.

PMID- 29175892 TI - Interrupted versus continuous suturing for vesicourethral anastomosis during radical prostatectomy: protocol for a systematic review and meta-analysis. AB - INTRODUCTION: Radical prostatectomy is the mainstay of treatment for prostate cancer. The vesicourethral anastomosis is a critical step, which most likely impacts urinary continence and urethral stenosis. To date, it still remains unclear whether interrupted and continuous suturing for the anastomosis have different outcomes. Therefore, the aim of this systematic review and meta analysis is to compare different suture techniques for vesicourethral anastomosis in terms of surgical and functional parameters. METHODS AND ANALYSIS: A comprehensive literature search will be conducted covering MEDLINE, Embase, Web of Science, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov. Studies comparing interrupted versus continuous suturing will be included in the analyses. No language restrictions will be applied. Screening, data extraction, statistical analysis and reporting will be done in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Quality assessment will be performed with the help of the Cochrane Collaboration's tool for assessing risk of bias and the Newcastle-Ottawa Scale for assessing quality of non-randomised studies. The quality of evidence will be evaluated with the Grading of Recommendations Assessment, Development and Evaluation. The primary outcome will be the time until removal of the urinary catheter. Secondary outcomes include rate of extravasation, length of hospital stay, time needed to perform the anastomosis, continence level at defined postoperative intervals and development of urethral strictures. Quantitative analysis will be calculated if meaningful. ETHICS AND DISSEMINATION: In order to meet the highest ethical and methodological standards. we followed the PRISMA Protocol 2015 checklist. Each item was answered appropriately. For systematic reviews the ethical issues are strictly methodological as only data that were published earlier will be used. The full manuscript will be submitted to a peer reviewed journal. Furthermore, the results will be presented on national and international congresses.

PMID- 29175893 TI - Oral corticosteroid dosing regimen and long-term prognosis in generalised myasthenia gravis: a multicentre cross-sectional study in Japan. AB - OBJECTIVE: We examined the correlation between the dosing regimen of oral prednisolone (PSL) and the achievement of minimal manifestation status or better on PSL <=5 mg/day lasting >6 months (the treatment target) in patients with generalised myasthenia gravis (MG). METHODS: We classified 590 patients with generalised MG into high-dose (n=237), intermediate-dose (n=187) and low-dose (n=166) groups based on the oral PSL dosing regimen, and compared the clinical characteristics, previous treatments other than PSL and prognosis between three groups. The effect of oral PSL dosing regimen on the achievement of the treatment target was followed for 3 years of treatment. RESULTS: To achieve the treatment target, ORs for low-dose versus high-dose regimen were 10.4 (P<0.0001) after 1 year of treatment, 2.75 (P=0.007) after 2 years and 1.86 (P=0.15) after 3 years; and those for low-dose versus intermediate-dose regimen were 13.4 (P<0.0001) after 1 year, 3.99 (P=0.0003) after 2 years and 4.92 (P=0.0004) after 3 years. Early combined use of fast-acting treatment (OR: 2.19 after 2 years, P=0.02; OR: 2.11 after 3 years, P=0.04) or calcineurin inhibitors (OR: 2.09 after 2 years, P=0.03; OR: 2.36 after 3 years, P=0.02) was associated positively with achievement of treatment target. CONCLUSION: A low-dose PSL regimen with early combination of other treatment options may ensure earlier achievement of the treatment target in generalised MG.

AB - BACKGROUND: Mutations in the gene coding for protein O-mannosyl-transferase 2 (POMT2) are known to cause severe congenital muscular dystrophy, and recently, mutations in POMT2 have also been linked to a milder limb-girdle muscular dystrophy (LGMD) phenotype, named LGMD type 2N (LGMD2N). Only four cases have been reported so far.ClinicalTrials.gov ID: NCT02759302 METHODS: We report 12 new cases of LGMD2N, aged 18-63 years. Muscle involvement was assessed by MRI, muscle strength testing and muscle biopsy analysis. Other clinical features were also recorded. RESULTS: Presenting symptoms were difficulties in walking, pain during exercise, delayed motor milestones and learning disabilities at school. All had some degree of cognitive impairment. Brain MRIs were abnormal in 3 of 10 patients, showing ventricular enlargement in one, periventricular hyperintensities in another and frontal atrophy of the left hemisphere in a third patient. Most affected muscle groups were hip and knee flexors and extensors on strength testing. On MRI, most affected muscles were hamstrings followed by paraspinal and gluteal muscles. The 12 patients in our cohort carried 11 alleles with known mutations, whereas 11 novel mutations accounted for the remaining 13 alleles. CONCLUSION: We describe the first cohort of patients with LGMD2N and show that unlike other LGMD types, all patients had cognitive impairment. Primary muscle involvement was found in hamstring, paraspinal and gluteal muscles on MRI, which correlated well with reduced muscle strength in hip and knee flexors and extensors. The study expands the mutational spectrum for LGMD2N, with the description of 11 novel POMT2 mutations in the association with LGMD2N. CLINICAL TRIAL REGISTRATION: NCT02759302. PMID- 29175899 TI - Prospective cohort study showing persistent HSV-2 shedding in women with genital herpes 2 years after acquisition. AB - OBJECTIVES: Herpes simplex virus type 2 (HSV-2) is a prevalent infection with great variability in clinical and virological manifestations among individuals. This prospective cohort study aims to evaluate the natural history of HSV-2 reactivation in the genital area in the same group of women over time. METHODS: Eighteen immunocompetent HSV-2 seropositive women were evaluated for viral shedding for 70 consecutive days within a median of 8 months (range 1-24 months) of HSV-2 acquisition and again approximately 2.5 years later from the original study. Participants obtained daily swabs of genital secretions for HSV PCR and recorded genital symptoms. RESULTS: The viral shedding rate was 29% during the initial study and 19% in the follow-up study (32% reduction, P=0.019). Subclinical shedding rate also decreased from 24% to 13% (37% reduction, P=0.032), as did the rate of days with genital lesions from 22% to 15% (33% reduction, P=0.24). The mean copy number during viral shedding remained unchanged over time at 4.8 log10 c/mL (SD=2.0 and 1.6 during each study, respectively, P=0.33). Women with high viral shedding rates in the past were likely to continue to have high shedding rates (r=0.63, P=0.005). CONCLUSIONS: Despite some reduction, high viral shedding rates persist in women with genital HSV-2 greater than 2 years after acquisition.

AB - Adipose tissue produces several adipokines that are enrolled in different metabolic and inflammatory pathways that may disturb iron metabolism and erythropoiesis. Considering that laparoscopic adjustable gastric banding (LAGB) has not been associated with a long-term risk of malabsorption, we performed a 13 month follow-up study in severe obese patients submitted to LAGB in order to clarify its impact on inflammation, iron metabolism and on red blood cell (RBC) biomarkers. Twenty obese patients were enrolled in the study, being clinical and analytically assessed before (T0) and 13 months after LAGB intervention (T1). Inflammation, iron bioavailability and RBC biomarkers were evaluated at T0 and T1. At T1, weight and anthropometric indices decreased significantly; patients showed a significant increase in mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration (MCHC), and a reduction in red cell distribution width, ferritin, hepcidin, tumor necrosis factor-alpha, interleukin-6 (IL-6) and C-reactive protein. Before LAGB, IL-6 correlated negatively with iron, hemoglobin concentration and MCHC; hepcidin correlated inversely with transferrin. Our data show that 13 months after LAGB, the weight loss is associated with an improvement in inflammation, namely a reduction in IL 6 that may reduce hepcidin production, improving iron availability for erythropoiesis, as shown by more adequate erythrocyte hemoglobinization.

AB - Objective To determine the effect of low dose aspirin on ulcer healing in patients with venous leg ulcers.Design Pragmatic, community based, parallel group, double blind, randomised controlled trial.Setting Five community nursing centres in New Zealand.Participants 251 adults with venous leg ulcers who could safely be treated with aspirin or placebo: 125 were randomised to aspirin and 126 to placebo.Interventions 150 mg oral aspirin daily or matching placebo for up to 24 weeks treatment, with compression therapy as standard background treatment.Main outcome measures The primary outcome was time to complete healing of the reference ulcer (largest ulcer if more than one ulcer was present). Secondary outcomes included proportion of participants healed, change in ulcer area, change in health related quality of life, and adverse events. Analysis was by intention to treat.Results The median number of days to healing of the reference ulcer was 77 in the aspirin group and 69 in the placebo group (hazard ratio 0.85, 95% confidence interval 0.64 to 1.13, P=0.25). The number of participants healed at the endpoint was 88 (70%) in the aspirin group and 101 (80%) in the placebo group (risk difference -9.8%, 95% confidence interval -20.4% to 0.9%, P=0.07). Estimated change in ulcer area was 4.1 cm2 in the aspirin group and 4.8 cm2 in the placebo group (mean difference -0.7 cm2, 95% confidence interval -1.9 to 0.5 cm2, P=0.25). 40 adverse events occurred among 29 participants in the aspirin group and 37 adverse events among 27 participants in the placebo group (incidence rate ratio 1.1, 95% confidence interval 0.7 to 1.7, P=0.71).Conclusion Our findings do not support the use of low dose aspirin as adjuvant treatment for venous leg ulcers.Trial registration ClinicalTrials.gov NCT02158806.

AB - A 'Switch' catalysis method is reviewed whereby a single catalyst is switched between ring-opening polymerization and ring-opening copolymerization cycles. It allows the efficient synthesis of block copolymers from mixtures of lactones, epoxides, anhydrides and carbon dioxide. In order to use and further develop such 'Switch' catalysis, it is important to understand how to monitor the catalysis and characterize the product block copolymers. Here, a step-by-step guide to both the catalysis and the identification of block copolymers is presented.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'. PMID- 29175905 TI - X-ray physico-chemical imaging during activation of cobalt-based Fischer-Tropsch synthesis catalysts. AB - The imaging of catalysts and other functional materials under reaction conditions has advanced significantly in recent years. The combination of the computed tomography (CT) approach with methods such as X-ray diffraction (XRD), X-ray fluorescence (XRF) and X-ray absorption near-edge spectroscopy (XANES) now enables local chemical and physical state information to be extracted from within the interiors of intact materials which are, by accident or design, inhomogeneous. In this work, we follow the phase evolution during the initial reduction step(s) to form Co metal, for Co-containing particles employed as Fischer-Tropsch synthesis (FTS) catalysts; firstly, working at small length scales (approx. micrometre spatial resolution), a combination of sample size and density allows for transmission of comparatively low energy signals enabling the recording of 'multimodal' tomography, i.e. simultaneous XRF-CT, XANES-CT and XRD CT. Subsequently, we show high-energy XRD-CT can be employed to reveal extent of reduction and uniformity of crystallite size on millimetre-sized TiO2 trilobes. In both studies, the CoO phase is seen to persist or else evolve under particular operating conditions and we speculate as to why this is observed.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'.

While this phenomenon has been well described in the literature, our case report is unique in describing diffuse pneumocephalus in the subaponeurotic space, subdural space, subarachnoid space, brain and ventricles without a break in the cranial vault: a 26-year-old man fell from a =9 meter scaffolding in a water tower. Following an arduous and delayed extrication, the patient was unresponsive with loss of pulse requiring intubation, cardiopulmonary resuscitation and release of tension pneumothorax with bilateral thoracostomy tubes. Examination remained poor with a Glasgow Coma Scale of 3. Immediate exploratory laparotomy was performed for a small right retroperitoneal haematoma on Focused Assessment with Sonography for Trauma. Postoperative imaging revealed diffuse pneumocephaly without facial fractures. This case presentation explores unusual causes of fistulous connections with the atmosphere that may lead to air trapped in and around the cranial vault. PMID- 29175904 TI - Cohesin SA2 is a sequence-independent DNA-binding protein that recognizes DNA replication and repair intermediates. AB - Proper chromosome alignment and segregation during mitosis depend on cohesion between sister chromatids, mediated by the cohesin protein complex, which also plays crucial roles in diverse genome maintenance pathways. Current models attribute DNA binding by cohesin to entrapment of dsDNA by the cohesin ring subunits (SMC1, SMC3, and RAD21 in humans). However, the biophysical properties and activities of the fourth core cohesin subunit SA2 (STAG2) are largely unknown. Here, using single-molecule atomic force and fluorescence microscopy imaging as well as fluorescence anisotropy measurements, we established that SA2 binds to both dsDNA and ssDNA, albeit with a higher binding affinity for ssDNA. We observed that SA2 can switch between the 1D diffusing (search) mode on dsDNA and stable binding (recognition) mode at ssDNA gaps. Although SA2 does not specifically bind to centromeric or telomeric sequences, it does recognize DNA structures often associated with DNA replication and double-strand break repair, such as a double-stranded end, single-stranded overhang, flap, fork, and ssDNA gap. SA2 loss leads to a defect in homologous recombination-mediated DNA double strand break repair. These results suggest that SA2 functions at intermediate DNA structures during DNA transactions in genome maintenance pathways. These findings have important implications for understanding the function of cohesin in these pathways. PMID- 29175907 TI - What is the cause of this fever? Malaria with concomitant pneumonia.

AB - Our previous studies of PAWS1 (protein associated with SMAD1; also known as FAM83G) have suggested that this molecule has roles beyond BMP signalling. To investigate these roles, we have used CRISPR/Cas9 to generate PAWS1-knockout U2OS osteosarcoma cells. Here, we show that PAWS1 plays a role in the regulation of the cytoskeletal machinery, including actin and focal adhesion dynamics, and cell migration. Confocal microscopy and live cell imaging of actin in U2OS cells indicate that PAWS1 is also involved in cytoskeletal dynamics and organization. Loss of PAWS1 causes severe defects in F-actin organization and distribution as well as in lamellipodial organization, resulting in impaired cell migration. PAWS1 interacts in a dynamic fashion with the actin/cytoskeletal regulator CD2AP at lamellae, suggesting that its association with CD2AP controls actin organization and cellular migration. Genetic ablation of CD2AP from U2OS cells instigates actin and cell migration defects reminiscent of those seen in PAWS1 knockout cells.This article has an associated First Person interview with the first authors of the paper.

PMID- 29175946 TI - Hypertrophied myocardium is vulnerable to ischemia/reperfusion injury and refractory to rapamycin-induced protection due to increased oxidative/nitrative stress. AB - Left ventricular hypertrophy (LVH) is causally related to increased morbidity and mortality following acute myocardial infarction (AMI) via still unknown mechanisms. Although rapamycin exerts cardioprotective effects against myocardial ischemia/reperfusion (MI/R) injury in normal animals, whether rapamycin-elicited cardioprotection is altered in the presence of LVH has yet to be determined. Pressure overload induced cardiac hypertrophied mice and sham-operated controls were exposed to AMI by coronary artery ligation, and treated with vehicle or rapamycin 10 min before reperfusion. Rapamycin produced marked cardioprotection in normal control mice, whereas pressure overload induced cardiac hypertrophied mice manifested enhanced myocardial injury, and was refractory to rapamycin elicited cardioprotection evidenced by augmented infarct size, aggravated cardiomyocyte apoptosis, and worsening cardiac function. Rapamycin alleviated MI/R injury via ERK-dependent antioxidative pathways in normal mice, whereas cardiac hypertrophied mice manifested markedly exacerbated oxidative/nitrative stress after MI/R evidenced by the increased iNOS/gp91phox expression, superoxide production, total NO metabolites, and nitrotyrosine content. Moreover, scavenging superoxide or peroxynitrite by selective gp91phox assembly inhibitor gp91ds-tat or ONOO- scavenger EUK134 markedly ameliorated MI/R injury, as shown by reduced myocardial oxidative/nitrative stress, alleviated myocardial infarction, hindered cardiomyocyte apoptosis, and improved cardiac function in aortic-banded mice. However, no additional cardioprotective effects were achieved when we combined rapamycin and gp91ds-tat or EUK134 in ischemic/reperfused hearts with or without LVH. These results suggest that cardiac hypertrophy attenuated rapamycin-induced cardioprotection by increasing oxidative/nitrative stress and scavenging superoxide/peroxynitrite protects the hypertrophied heart from MI/R. PMID- 29175948 TI - Increased nonHDL cholesterol levels cause muscle wasting and ambulatory dysfunction in the mouse model of LGMD2B. AB - Progressive limb and girdle muscle atrophy leading to loss of ambulation is a hallmark of dysferlinopathies, which include limb-girdle muscular dystrophy type 2B and Miyoshi myopathy. However, animal models fail to fully reproduce the disease severity observed in humans, with dysferlin-null (Dysf-/-) mice exhibiting minor muscle damage and weakness without dramatic ambulatory dysfunction. As we have previously reported significant Dysf expression in blood vessels, we investigated the role of vascular function in development of muscle pathology by generating a Dysf-deficient mouse model with vascular disease. This was achieved by crossing Dysf-/- mice with ApoE-/- mice, which have high levels of nonHDL-associated cholesterol. Double-knockout Dysf-/-ApoE-/- mice exhibited severe ambulatory dysfunction by 11 months of age. In limb-girdle muscles, histology confirmed dramatic muscle wasting, fibrofatty replacement, and myofiber damage in Dysf-/-ApoE-/- mice without affecting the ratio of centrally nucleated myofibers. Although there were no major changes in ex vivo diaphragm and soleus muscle function, histological analyses revealed these muscles to be untouched by damage and remodelling. In all, these data suggest that cholesterol may be deleterious to dysferlinopathic muscle and lead to ambulatory dysfunction. Moreover, differences in plasma lipid handling between mice and humans could be a key factor affecting dysferlinopathy severity.

AB - Renewable carbon feedstocks such as biomass and CO2 present an important element of future circular economy. Especially biomass as highly functionalized feedstock provides manifold opportunities for the transformation into attractive platform chemicals. However, this change of the resources requires a paradigm shift in refinery design. Fossil feedstocks are processed in gas phase at elevated temperature. In contrast, biorefineries are based on processes in polar solvents at moderate conditions to selectively deoxygenate the polar, often thermally instable and high-boiling molecules. Here, challenges of catalytic deoxygenation, novel strategies for separation and opportunities provided at the interface to biotechnology are discussed in form of showcases.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'.

PMID- 29175952 TI - Modulation of Ether-a-Go-Go Related Gene (ERG) Current Governs Intrinsic Persistent Activity in Rodent Neocortical Pyramidal Cells. AB - While cholinergic receptor activation has long been known to dramatically enhance the excitability of cortical neurons, the cellular mechanisms responsible for this effect are not well understood. We used intracellular recordings in rat (both sexes) neocortical brain slices to assess the ionic mechanisms supporting persistent firing modes triggered by depolarizing stimuli following cholinergic receptor activation. We found multiple lines of evidence suggesting that a component of the underlying hyperexcitability associated with persistent firing reflects a reduction in the standing (leak) K+ current mediated by Ether-a-go-go Related Gene (ERG) channels. Three chemically diverse ERG channel blockers (terfenadine, ErgToxin-1, and E-4031) abolished persistent firing and the underlying increase in input resistance in deep pyramidal cells in temporal and prefrontal association neocortex. Calcium accumulation during triggering stimuli appears to attenuate ERG currents, leading to membrane potential depolarization and increased input resistance, two critical elements generating persistent firing. Our results also suggest that ERG current normally governs cortical neuron responses to depolarizing stimuli by opposing prolonged discharges and by enhancing the poststimulus repolarization. The broad expression of ERG channels and the ability of ERG blocks to abolish persistent firing evoked by both synaptic and intracellular step stimuli suggest that modulation of ERG channels may underlie many forms of persistent activity observed in vivoSIGNIFICANCE STATEMENT Persistent activity, where spiking continues beyond the triggering stimulus, is a common phenomenon observed in many types of neurons. Identifying the mechanism underlying this elementary process of memory is a step forward in understanding higher cognitive function including short-term memory. Our results suggest that a reduction in the currents normally mediated by Ether-a-go-go Related Gene (ERG) K+ channels contributes to persistent firing in neocortical pyramidal cells. ERG currents have been previously studied primarily in the heart; relatively little is known about ERG function in the brain, although mutations in ERG channels have recently been linked to schizophrenia. The present study is among the first to describe its role in neocortex in relation to biophysical correlates of memory function. PMID- 29175953 TI - Distinct Roles of Different Presynaptic and Postsynaptic NCAM Isoforms in Early Motoneuron-Myotube Interactions Required for Functional Synapse Formation. AB - The neural cell adhesion molecule (NCAM) is expressed both presynaptically and postsynaptically during neuromuscular junction formation. Genetic deletion in mice of all three isoforms (180, 140, and 120 kDa), or just the 180 isoform, suggested that different isoforms played distinct roles in synaptic maturation. Here we characterized in mice of either sex the earliest adhesive contacts between the growth cones of motoneurons and myotubes and their subsequent maturation into functional synapses in cocultures of motoneurons and myotubes, which expressed their normal complement of NCAM isoforms, or were lacking all isoforms either presynaptically or postsynaptically. Growth cone contact with +/+ mouse myotubes resulted in immediate adhesive contacts and the rapid downregulation of growth cone motility. When contacting NCAM-/- myotubes, growth cones touched and retracted/collapsed multiple times and failed to form stable contacts, even after 10 h. Exogenous expression in myotubes of either the 180 or 140 isoform, but not the 120 kDa isoform, rescued the rapid formation of stable contacts, the accumulation of presynaptic and postsynaptic molecules, and functional transmission. When NCAM was absent only in motoneurons, growth cones did not retract upon myotube contact, but, since their motility was not downregulated, they grew off the ends of the myotubes, failing to form synapses. The agrin receptor Lrp4 was strongly downregulated in NCAM-negative myotubes, and motoneuron growth cones did not make stable contacts with Lrp4-negative myotubes. These studies have identified novel roles for presynaptic and postsynaptic NCAM in mediating early cell-cell interactions required for synapse formation.SIGNIFICANCE STATEMENT Although many molecular signals needed to form the functionally effective neuromuscular synapses required for normal movement have been described, the earliest signals that let motoneuron growth cones make stable adhesive contacts with myotubes and cease motility are not well understood. Using dynamic imaging of motoneuron-myotube cocultures, we show that NCAM is required on both the growth cone and myotube and that different NCAM isoforms mediate initial adhesion and the downregulation of growth cone motility. The agrin receptor Lrp4 was also essential for initial adhesive contacts and was downregulated on NCAM-/- myotubes. Our identification of novel roles for NCAM and Lrp4 and possible interactions between them in transforming motile growth cones into stable contacts opens interesting new avenues for exploration. PMID- 29175954 TI - CD44 Signaling Mediates High Molecular Weight Hyaluronan-Induced Antihyperalgesia. AB - We studied, in male Sprague Dawley rats, the role of the cognate hyaluronan receptor, CD44 signaling in the antihyperalgesia induced by high molecular weight hyaluronan (HMWH). Low molecular weight hyaluronan (LMWH) acts at both peptidergic and nonpeptidergic nociceptors to induce mechanical hyperalgesia that is prevented by intrathecal oligodeoxynucleotide antisense to CD44 mRNA, which also prevents hyperalgesia induced by a CD44 receptor agonist, A6. Ongoing LMWH and A6 hyperalgesia are reversed by HMWH. HMWH also reverses the hyperalgesia induced by diverse pronociceptive mediators, prostaglandin E2, epinephrine, TNFalpha, and interleukin-6, and the neuropathic pain induced by the cancer chemotherapy paclitaxel. Although CD44 antisense has no effect on the hyperalgesia induced by inflammatory mediators or paclitaxel, it eliminates the antihyperalgesic effect of HMWH. HMWH also reverses the hyperalgesia induced by activation of intracellular second messengers, PKA and PKCepsilon, indicating that HMWH-induced antihyperalgesia, although dependent on CD44, is mediated by an intracellular signaling pathway rather than as a competitive receptor antagonist. Sensitization of cultured small-diameter DRG neurons by prostaglandin E2 is also prevented and reversed by HMWH. These results demonstrate the central role of CD44 signaling in HMWH-induced antihyperalgesia, and establish it as a therapeutic target against inflammatory and neuropathic pain.SIGNIFICANCE STATEMENT We demonstrate that hyaluronan (HA) with different molecular weights produces opposing nociceptive effects. While low molecular weight HA increases sensitivity to mechanical stimulation, high molecular weight HA reduces sensitization, attenuating inflammatory and neuropathic hyperalgesia. Both pronociceptive and antinociceptive effects of HA are mediated by activation of signaling pathways downstream CD44, the cognate HA receptor, in nociceptors. These results contribute to our understanding of the role of the extracellular matrix in pain, and indicate CD44 as a potential therapeutic target to alleviate inflammatory and neuropathic pain. PMID- 29175956 TI - The Mouse Pulvinar Nucleus Links the Lateral Extrastriate Cortex, Striatum, and Amygdala. AB - The pulvinar nucleus is a large thalamic structure involved in the integration of visual and motor signals. The pulvinar forms extensive connections with striate and extrastriate cortical areas, but the impact of these connections on cortical circuits has not previously been directly tested. Using a variety of anatomical, optogenetic, and in vitro physiological techniques in male and female mice, we show that pulvinocortical terminals are densely distributed in the extrastriate cortex where they form synaptic connections with spines and small-diameter dendrites. Optogenetic activation of these synapses in vitro evoked large excitatory postsynaptic responses in the majority of pyramidal cells, spiny stellate cells, and interneurons within the extrastriate cortex. However, specificity in pulvinar targeting was revealed when recordings were targeted to projection neuron subtypes. The neurons most responsive to pulvinar input were those that project to the striatum and amygdala (76% responsive) or V1 (55%), whereas neurons that project to the superior colliculus were rarely responsive (6%). Because the pulvinar also projects directly to the striatum and amygdala, these results establish the pulvinar nucleus as a hub linking the visual cortex with subcortical regions involved in the initiation and control of movement. We suggest that these circuits may be particularly important for coordinating body movements and visual perception.SIGNIFICANCE STATEMENT We found that the pulvinar nucleus can strongly influence extrastriate cortical circuits and exerts a particularly strong impact on the activity of extrastriate neurons that project to the striatum and amygdala. Our results suggest that the conventional hierarchical view of visual cortical processing may not apply to the mouse visual cortex. Instead, our results establish the pulvinar nucleus as a hub linking the visual cortex with subcortical regions involved in the initiation and control of movement, and predict that the execution of visually guided movements relies on this network. PMID- 29175955 TI - The Autism Protein Ube3A/E6AP Remodels Neuronal Dendritic Arborization via Caspase-Dependent Microtubule Destabilization. AB - UBE3A gene copy number variation and the resulting overexpression of the protein E6AP is directly linked to autism spectrum disorders (ASDs). However, the underlying cellular and molecular neurobiology remains less clear. Here we report the role of ASD-related increased dosage of Ube3A/E6AP in dendritic arborization during brain development. We show that increased E6AP expression in primary cultured neurons leads to a reduction in dendritic branch number and length. The E6AP-dependent remodeling of dendritic arborization results from retraction of dendrites by thinning and fragmentation at the tips of dendrite branches, leading to shortening or removal of dendrites. This remodeling effect is mediated by the ubiquitination and degradation of XIAP (X-linked inhibitors of aptosis protein) by E6AP, which leads to activation of caspase-3 and cleavage of microtubules. In vivo, male and female Ube3A 2X ASD mice show decreased XIAP levels, increased caspase-3 activation, and elevated levels of tubulin cleavage. Consistently, dendritic branching and spine density are reduced in cortical neurons of Ube3A 2X ASD mice. In revealing an important role for Ube3A/E6AP in ASD-related developmental alteration in dendritic arborization and synapse formation, our findings provide new insights into the pathogenesis of Ube3A/E6AP-dependent ASD.SIGNIFICANCE STATEMENT Copy number variation of the UBE3A gene and aberrant overexpression of the gene product E6AP protein is a common cause of autism spectrum disorders (ASDs). During brain development, dendritic growth and remodeling play crucial roles in neuronal connectivity and information integration. We found that in primary neurons and in Ube3A transgenic autism mouse brain, overexpression of E6AP leads to significant loss of dendritic arborization. This effect is mediated by the ubiquitination of XIAP (X-linked inhibitor of aptosis protein) by E6AP, subsequent activation of caspases, and the eventual cleavage of microtubules, leading to local degeneration and retraction at the tips of dendritic branches. These findings demonstrate dysregulation in neuronal structural stability as a major cellular neuropathology in ASD. PMID- 29175957 TI - Brainstem Pain-Control Circuitry Connectivity in Chronic Neuropathic Pain. AB - Preclinical investigations have suggested that altered functioning of brainstem pain-modulation circuits may be crucial for the maintenance of some chronic pain conditions. While some human psychophysical studies show that patients with chronic pain display altered pain-modulation efficacy, it remains unknown whether brainstem pain-modulation circuits are altered in individuals with chronic pain. The aim of the present investigation was to determine whether, in humans, chronic pain following nerve injury is associated with altered ongoing functioning of the brainstem descending modulation systems. Using resting-state functional magnetic resonance imaging, we found that male and female patients with chronic neuropathic orofacial pain show increased functional connectivity between the rostral ventromedial medulla (RVM) and other brainstem pain-modulatory regions, including the ventrolateral periaqueductal gray (vlPAG) and locus ceruleus (LC). We also identified an increase in RVM functional connectivity with the region that receives orofacial nociceptor afferents, the spinal trigeminal nucleus. In addition, the vlPAG and LC displayed increased functional connectivity strengths with higher brain regions, including the hippocampus, nucleus accumbens, and anterior cingulate cortex, in individuals with chronic pain. These data reveal that chronic pain is associated with altered ongoing functioning within the endogenous pain-modulation network. These changes may underlie enhanced descending facilitation of processing at the primary synapse, resulting in increased nociceptive transmission to higher brain centers. Further, our findings show that higher brain regions interact with the brainstem modulation system differently in chronic pain, possibly reflecting top-down engagement of the circuitry alongside altered reward processing in pain conditions.SIGNIFICANCE STATEMENT Experimental animal models and human psychophysical studies suggest that altered functioning of brainstem pain-modulation systems contributes to the maintenance of chronic pain. However, the function of this circuitry has not yet been explored in humans with chronic pain. In this study, we report that individuals with orofacial neuropathic pain show altered functional connectivity between regions within the brainstem pain-modulation network. We suggest that these changes reflect largely central mechanisms that feed back onto the primary nociceptive synapse and enhance the transfer of noxious information to higher brain regions, thus contributing to the constant perception of pain. Identifying the mechanisms responsible for the maintenance of neuropathic pain is imperative for the development of more efficacious therapies. PMID- 29175958 TI - Amphetamine Reverses Escalated Cocaine Intake via Restoration of Dopamine Transporter Conformation. AB - Cocaine abuse disrupts dopamine system function, and reduces cocaine inhibition of the dopamine transporter (DAT), which results in tolerance. Although tolerance is a hallmark of cocaine addiction and a DSM-V criterion for substance abuse disorders, the molecular adaptations producing tolerance are unknown, and testing the impact of DAT changes on drug taking behaviors has proven difficult. In regard to treatment, amphetamine has shown efficacy in reducing cocaine intake; however, the mechanisms underlying these effects have not been explored. The goals of this study were twofold; we sought to (1) identify the molecular mechanisms by which cocaine exposure produces tolerance and (2) determine whether amphetamine-induced reductions in cocaine intake are connected to these mechanisms. Using cocaine self-administration and fast-scan cyclic voltammetry in male rats, we show that low-dose, continuous amphetamine treatment, during self administration or abstinence, completely reversed cocaine tolerance. Amphetamine treatment also reversed escalated cocaine intake and decreased motivation to obtain cocaine as measured in a behavioral economics task, thereby linking tolerance to multiple facets of cocaine use. Finally, using fluorescence resonance energy transfer imaging, we found that cocaine tolerance is associated with the formation of DAT-DAT complexes, and that amphetamine disperses these complexes. In addition to extending our basic understanding of DATs and their role in cocaine reinforcement, we serendipitously identified a novel therapeutic target: DAT oligomer complexes. We show that dispersion of oligomers is concomitant with reduced cocaine intake, and propose that pharmacotherapeutics aimed at these complexes may have potential for cocaine addiction treatment.SIGNIFICANCE STATEMENT Tolerance to cocaine's subjective effects is a cardinal symptom of cocaine addiction and a DSM-V criterion for substance abuse disorders. However, elucidating the molecular adaptions that produce tolerance and determining its behavioral impact have proven difficult. Using cocaine self administration in rats, we link tolerance to cocaine effects at the dopamine transporter (DAT) with aberrant cocaine-taking behaviors. Further, tolerance was associated with multi-DAT complexes, which formed after cocaine exposure. Treatment with amphetamine deconstructed DAT complexes, reversed tolerance, and decreased cocaine seeking. These data describe the behavioral consequence of cocaine tolerance, provide a putative mechanism for its development, and suggest that compounds that disperse DAT complexes may be efficacious treatments for cocaine addiction. PMID- 29175960 TI - Silver-palladium catalysts for the direct synthesis of hydrogen peroxide. AB - A series of bimetallic silver-palladium catalysts supported on titania were prepared by wet impregnation and assessed for the direct synthesis of hydrogen peroxide, and its subsequent side reactions. The addition of silver to a palladium catalyst was found to significantly decrease hydrogen peroxide productivity and hydrogenation, but crucially increase the rate of decomposition. The decomposition product, which is predominantly hydroxyl radicals, can be used to decrease bacterial colonies. The interaction between silver and palladium was characterized using scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy (XPS) and temperature programmed reduction (TPR). The results of the TPR and XPS indicated the formation of a silver-palladium alloy. The optimal 1% Ag-4% Pd/TiO2 bimetallic catalyst was able to produce approximately 200 ppm of H2O2 in 30 min. The findings demonstrate that AgPd/TiO2 catalysts are active for the synthesis of hydrogen peroxide and its subsequent decomposition to reactive oxygen species. The catalysts are promising for use in wastewater treatment as they combine the disinfectant properties of silver, hydrogen peroxide production and subsequent decomposition.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'. PMID- 29175959 TI - Disrupted Neuroglial Metabolic Coupling after Peripheral Surgery. AB - Immune-related events in the periphery can remotely affect brain function, contributing to neurodegenerative processes and cognitive decline. In mice, peripheral surgery induces a systemic inflammatory response associated with changes in hippocampal synaptic plasticity and transient cognitive decline, however, the underlying mechanisms remain unknown. Here we investigated the effect of peripheral surgery on neuronal-glial function within hippocampal neuronal circuits of relevance to cognitive processing in male mice at 6, 24, and 72 h postsurgery. At 6 h we detect the proinflammatory cytokine IL-6 in the hippocampus, followed up by alterations in the mRNA and protein expression of astrocytic and neuronal proteins necessary for optimal energy supply to the brain and for the reuptake and recycling of glutamate in the synapse. Similarly, at 24 h postsurgery the mRNA expression of structural proteins (GFAP and AQP4) was compromised. At this time point, functional analysis in astrocytes revealed a decrease in resting calcium signaling. Examination of neuronal activity by whole cell patch-clamp shows elevated levels of glutamatergic transmission and changes in AMPA receptor subunit composition at 72 h postsurgery. Finally, lactate, an essential energy substrate produced by astrocytes and critical for memory formation, decreases at 6 and 72 h after surgery. Based on temporal parallels with our previous studies, we propose that the previously reported cognitive decline observed at 72 h postsurgery in mice might be the consequence of temporal hippocampal metabolic, structural, and functional changes in astrocytes that lead to a disruption of the neuroglial metabolic coupling and consequently to a neuronal dysfunction.SIGNIFICANCE STATEMENT A growing body of evidence suggests that surgical trauma launches a systemic inflammatory response that reaches the brain and associates with immune activation and cognitive decline. Understanding the mechanisms by which immune-related events in the periphery can influence brain processes is essential for the development of therapies to prevent or treat postoperative cognitive dysfunction and other forms of cognitive decline related to immune-to-brain communication, such as Alzheimer's and Parkinson's diseases. Here we describe the temporal orchestration of a series of metabolic, structural, and functional changes after aseptic trauma in mice related to astrocytes and later in neurons that emphasize the role of astrocytes as key intermediaries between peripheral immune events, neuronal processing, and potentially cognition.

This is partly due to the complex and varied nature of these interests, and the limited evidence available regarding their prevalence and impact on biomedical research and clinical practice. We suggest that there are no meaningful conceptual distinctions, and few practical differences, between financial and non-financial conflicts of interest, and accordingly, that both require careful consideration. Further, a better understanding of the complexities of non-financial conflicts of interest, and their entanglement with financial conflicts of interest, may assist in the development of a more sophisticated approach to all forms of conflicts of interest. PMID- 29175968 TI - Learning health systems, clinical equipoise and the ethics of response adaptive randomisation. AB - To give substance to the rhetoric of 'learning health systems', a variety of novel trial designs are being explored to more seamlessly integrate research with medical practice, reduce study duration and reduce the number of participants allocated to ineffective interventions. Many of these designs rely on response adaptive randomisation (RAR). However, critics charge that RAR is unethical on the grounds that it violates the principle of equipoise. In this paper, I reconstruct critiques of RAR as holding that it is inconsistent with five important ethical principles. I then argue that these criticisms rest on a faulty view of equipoise encouraged by the idea that a RAR study models the beliefs of a single rational agent about the relative merits of the interventions being studied. I outline a view in which RAR models an idealised health system in which diverse communities of fully informed experts shrink or grow as their constituent members update their expert opinions in light of reliable medical evidence. I show how a proper understanding of clinical equipoise can reconcile this conception of RAR with these five ethical principles. This analysis removes an in principle objection to RAR and sheds important light on the relationship between clinical equipoise and transient diversity in the scientific community. PMID- 29175969 TI - Time and motion studies of National Health Service cataract theatre lists to determine strategies to improve efficiency. AB - AIM: To provide a quantitative assessment of cataract theatre lists focusing on productivity and staffing levels/tasks using time and motion studies. METHODS: National Health Service (NHS) cataract theatre lists were prospectively observed in five different institutions (four NHS hospitals and one private hospital). Individual tasks and their timings of every member of staff were recorded. Multiple linear regression analyses were performed to investigate possible associations between individual timings and tasks. RESULTS: 140 operations were studied over 18 theatre sessions. The median number of scheduled cataract operations was 7 (range: 5-14). The average duration of an operation was 10.3 min+/-(SD 4.11 min). The average time to complete one case including patient turnaround was 19.97 min (SD 8.77 min). The proportion of the surgeons' time occupied on total duties or operating ranged from 65.2% to 76.1% and from 42.4% to 56.7%, respectively. The correlations of the surgical time to patient time in theatre was R2=0.95. A multiple linear regression model found a significant association (F(3,111)=32.86, P<0.001) with R2=0.47 between the duration of one operation and the number of allied healthcare professionals (AHPs), the number of AHP key tasks and the time taken to perform these key tasks by the AHPs. CONCLUSIONS: Significant variability in the number of cases performed and the efficiency of patient flow were found between different institutions. Time and motion studies identified requirements for high-volume models and factors relating to performance. Supporting the surgeon with sufficient AHPs and tasks performed by AHPs could improve surgical efficiency up to approximately double productivity over conventional theatre models. PMID- 29175970 TI - Macular thickness profile and diabetic retinopathy: the Singapore Epidemiology of Eye Diseases Study. AB - BACKGROUND: To evaluate retinal thickness profiles in eyes with and without diabetic retinopathy (DR) using spectral-domain optical coherence tomography (SD OCT) among individuals with diabetes. METHODS: Participants were recruited from the Singapore Epidemiology of Eye Diseases Study, a population-based study among Chinese, Malays and Indians aged 40 years or older residing in Singapore. All participants underwent standardised systemic and ophthalmic examinations. Average thickness of the macula, ganglion cell-inner plexiform layer and outer retina layer (from the outer plexiform layer to the retinal pigment epithelium layer) were measured using SD-OCT. DR status and severity were graded based on fundus photographs using the modified Airlie House classification system. Participants with macular oedema were excluded. RESULTS: 2240 eyes from 1280 participants were included. Of these, 1764 (78.7%) eyes had no DR, 351 (15.7%) eyes had minimal or mild DR and 125 (5.6%) eyes had moderate or worse DR. After adjusting for age, gender, ethnicity, axial length, hypertension, glycated haemoglobin, body mass index, total cholesterol and diabetes duration, eyes with DR had thicker macula (245.44 um vs 243.04 um, P=0.03) and outer retina (124.26 um vs 123.08 um, P=0.01) than eyes without DR. When stratified by DR severity, thicker macula (250.24 um vs 242.88 um, P=0.011) and outer retina (126.4 um vs 123.0 MUm, P=0.006) were observed in eyes with moderate or worse, but not minimal or mild DR, compared with eyes without DR. CONCLUSIONS: Even in the absence of macular oedema, eyes with DR, particularly those with more severe DR, had thicker macular and outer retinal layers than eyes without DR. PMID- 29175971 TI - The Gender Reveal: Implications of a Cultural Tradition for Pediatric Health. PMID- 29175972 TI - Academic Achievement and Physical Activity: A Meta-analysis. AB - CONTEXT: The effect of physical activity (PA) on different areas of academic achievement and classroom behaviors and how different characteristics of PA interventions could modify the effect remain unclear. OBJECTIVE: The objective was twofold: (1) to assess the effect of PA interventions on academic achievement and classroom behaviors in childhood and (2) to determine the characteristics of individuals and PA programs that enhance academic performance. DATA SOURCES: We identified studies from the database inception to October 16, 2016. STUDY SELECTION: We selected intervention studies aimed at examining the effect of exercise on academic achievement and classroom behaviors at developmental age. DATA EXTRACTION: Random-effects models were used to calculate pooled effect size for all primary outcomes (language- and mathematics-related skills, reading, composite score, and time in on-task behavior). Positive values represent a direct relationship between PA programs and academic achievement scores or on task behaviors. RESULTS: A total of 26 studies (10 205 children, aged from 4 to 13) were included. Pooled effect size (95% confidence interval) estimates were as follows: (1) 0.16 (-0.06 to 0.37) for language-related skills; (2) 0.21 (0.09 to 0.33) for mathematics-related skills; (3) 0.13 (0.02 to 0.24) for reading; (4) 0.26 (0.07 to 0.45) for composite scores; and (5) 0.77 (0.22 to 1.32) for time in on-task behaviors. LIMITATIONS: Limitations included the variety of tools used to measure academic achievement and the limited number of studies that reported the effect of after-school PA interventions. CONCLUSIONS: PA, especially physical education, improves classroom behaviors and benefits several aspects of academic achievement, especially mathematics-related skills, reading, and composite scores in youth. PMID- 29175974 TI - Paediatric inflammatory bowel disease: improving early diagnosis. PMID- 29175973 TI - Accuracy of Clinician Suspicion of Lyme Disease in the Emergency Department. AB - BACKGROUND: To make initial management decisions, clinicians must estimate the probability of Lyme disease before diagnostic test results are available. Our objective was to examine the accuracy of clinician suspicion for Lyme disease in children undergoing evaluation for Lyme disease. METHODS: We assembled a prospective cohort of children aged 1 to 21 years who were evaluated for Lyme disease at 1 of the 5 participating emergency departments. Treating physicians were asked to estimate the probability of Lyme disease (on a 10-point scale). We defined a Lyme disease case as a patient with an erythema migrans lesion or positive 2-tiered serology results in a patient with compatible symptoms. We calculated the area under the curve for the receiver operating curve as a measure of the ability of clinician suspicion to diagnose Lyme disease. RESULTS: We enrolled 1021 children with a median age of 9 years (interquartile range, 5-13 years). Of these, 238 (23%) had Lyme disease. Clinician suspicion had a minimal ability to discriminate between children with and without Lyme disease: area under the curve, 0.75 (95% confidence interval, 0.71-0.79). Of the 554 children who the treating clinicians thought were unlikely to have Lyme disease (score 1 3), 65 (12%) had Lyme disease, and of the 127 children who the treating clinicians thought were very likely to have Lyme disease (score 8-10), 39 (31%) did not have Lyme disease. CONCLUSIONS: Because clinician suspicion had only minimal accuracy for the diagnosis of Lyme disease, laboratory confirmation is required to avoid both under- and overdiagnosis. PMID- 29175975 TI - Lamin and the heart. AB - Lamins A and C are intermediate filament nuclear envelope proteins encoded by the LMNA gene. Mutations in LMNA cause autosomal dominant severe heart disease, accounting for 10% of dilated cardiomyopathy (DCM). Characterised by progressive conduction system disease, arrhythmia and systolic impairment, lamin A/C heart disease is more malignant than other common DCMs due to high event rates even when the left ventricular impairment is mild. It has several phenotypic mimics, but overall it is likely to be an under-recognised cause of DCM. In certain clinical scenarios, particularly familial DCM with early conduction disease, the pretest probability of finding an LMNA mutation may be quite high.Recognising lamin A/C heart disease is important because implantable cardioverter defibrillators need to be implanted early. Promising oral drug therapies are within reach thanks to research into the mitogen-activated protein kinase (MAPK) and affiliated pathways. Personalised heart failure therapy may soon become feasible for LMNA, alongside personalised risk stratification, as variant-related differences in phenotype severity and clinical course are being steadily elucidated.Genotyping and family screening are clinically important both to confirm and to exclude LMNA mutations, but it is the three-pronged integration of such genetic information with functional data from in vivo cardiomyocyte mechanics, and pathological data from microscopy of the nuclear envelope, that is properly reshaping our LMNA knowledge base, one variant at a time. This review explains the biology of lamin A/C heart disease (genetics, structure and function of lamins), clinical presentation (diagnostic pointers, electrocardiographic and imaging features), aspects of screening and management, including current uncertainties, and future directions. PMID- 29175976 TI - Heart rate at first postdischarge visit and outcomes in patients with heart failure. AB - OBJECTIVE: Heart rate control is important to prevent adverse outcomes in patients with heart failure (HF). However, postdischarge activity may worsen heart rate control, resulting in readmission. This study aimed to explore the implications of the heart rate differences between discharge and the first outpatient visit (D-O diff). METHODS: We retrospectively identified 458 patients (male: 46%; mean age: 72 years) discharged after HF. The heart rates at admission, discharge and first outpatient visit were analysed. The primary outcome was a composite of cardiovascular (CV) death and readmission of non-fatal myocardial infarction (MI), non-fatal stroke or non-fatal HF over a mean follow up of 16 months. RESULTS: During follow-up, the clinical outcomes were noted in 223 patients (49%): HF, 199; stroke, 9; MI, 6; CV death, 9. The heart rate at the first outpatient visit (r=-0.311, P<0.001) and D-O diff (r=0.416, P<0.001) showed a better correlation with the time-to-clinical event than the heart rate at admission or discharge. The events group displayed a pronounced heart rate increase (13 beats/min) from discharge to the first outpatient visit compared with the event-free group (a decrease of 2 beats/min). A decrease less than -15 in the D-O diff showed a 4.5-fold risk of clinical outcomes during follow-up (P<0.001). CONCLUSIONS: A decreased D-O diff was related to the adverse outcomes of HF. The failure of heart rate control within more than 15 beats/min at the first outpatient visit was an independent factor for CV events.

PMID- 29175978 TI - Constrictive pericarditis: diagnosis, management and clinical outcomes. AB - Constrictive pericarditis (CP) is a form of diastolic heart failure that arises because an inelastic pericardium inhibits cardiac filling. This disorder must be considered in the differential diagnosis for unexplained heart failure, particularly when the left ventricular ejection fraction is preserved. Risk factors for the development of CP include prior cardiac surgery and radiation therapy, but most cases are still deemed to be idiopathic. Making the diagnosis may be challenging and requires meticulous echocardiographic assessment, often supplemented by cross-sectional cardiac imaging and haemodynamic catheterisation. The key pathophysiological concepts, which serve as the basis for many of the diagnostic criteria, remain: (1) dissociation of intrathoracic and intracardiac pressures and (2) enhanced ventricular interaction. Complete surgical pericardiectomy is the only effective treatment for chronic CP. A subset of patients with subacute inflammatory CP, often identified by cardiac MRI, may respond to anti-inflammatory treatments. PMID- 29175979 TI - Takayasu arteritis: challenges in diagnosis and management. AB - Takayasu arteritis (TA) is a rare disease affecting chiefly young women, although it can affect both men and women and persons of many different ethnicities. TA carries a high morbidity rate, but importantly, overall mortality has declined over time such that the 15-year survival rate has increased from 82.9% for patients diagnosed between 1957 and 1975 to 96.5% for those diagnosed from 1976 to 1990. Severity of presenting arterial complications and delay to diagnosis have also decreased over the past decade owing to advances in non-invasive diagnostic imaging and the development of medical therapies. Despite these advances, there still remain significant gaps in the diagnosis and management of these complex patients. These gaps encompass the basic, yet extremely complex, tasks of defining a universally accepted diagnostic criterion, accurate assessment of disease activity and development of clinically meaningful and accurate outcome measures to guide necessary clinical trials for the management of these complex patients. PMID- 29175980 TI - Glioma Survival Prediction with Combined Analysis of In Vivo 11C-MET PET Features, Ex Vivo Features, and Patient Features by Supervised Machine Learning. AB - Gliomas are the most common type of tumor in the brain. Although the definite diagnosis is routinely made ex vivo by histopathologic and molecular examination, diagnostic work-up of patients with suspected glioma is mainly done using MRI. Nevertheless, l-S-methyl-11C-methionine (11C-MET) PET holds great potential in the characterization of gliomas. The aim of this study was to establish machine learning-driven survival models for glioma built on in vivo 11C-MET PET characteristics, ex vivo characteristics, and patient characteristics. Methods: The study included 70 patients with a treatment-naive glioma that was 11C-MET positive and had histopathology-derived ex vivo feature extraction, such as World Health Organization 2007 tumor grade, histology, and isocitrate dehydrogenase 1 R132H mutational status. The 11C-MET-positive primary tumors were delineated semiautomatically on PET images, followed by the extraction of tumor-to background-based general and higher-order textural features by applying 5 different binning approaches. In vivo and ex vivo features, as well as patient characteristics (age, weight, height, body mass index, Karnofsky score), were merged to characterize the tumors. Machine-learning approaches were used to identify relevant in vivo, ex vivo, and patient features and their relative weights for predicting 36-mo survival. The resulting feature weights were used to establish 3 predictive models per binning configuration: one model based on a combination of in vivo, ex vivo, and clinical patient information (M36IEP); another based on in vivo and patient information only (M36IP); and a third based on in vivo information only (M36I). In addition, a binning-independent model based on ex vivo and patient information only (M36EP) was created. The established models were validated in a Monte Carlo cross-validation scheme. Results: The most prominent machine-learning-selected and -weighted features were patient-based and ex vivo-based, followed by in vivo-based. The highest areas under the curve for our models as revealed by the Monte Carlo cross-validation were 0.9 for M36IEP, 0.87 for M36EP, 0.77 for M36IP, and 0.72 for M36IConclusion: Prediction of survival in amino acid PET-positive glioma patients was highly accurate using computer-supported predictive models based on in vivo, ex vivo, and patient features. PMID- 29175981 TI - Validation of Noninvasive Tracer Kinetic Analysis of 18F-Florbetaben PET Using a Dual-Time-Window Acquisition Protocol. AB - Accurate amyloid PET quantification is necessary for monitoring amyloid-beta accumulation and response to therapy. Currently, most of the studies are analyzed using the static SUV ratio (SUVR) approach because of its simplicity. However, this approach may be influenced by changes in cerebral blood flow (CBF) or radiotracer clearance. Full tracer kinetic models require arterial blood sampling and dynamic image acquisition. The objectives of this work were, first, to validate a noninvasive kinetic modeling approach for 18F-florbetaben PET using an acquisition protocol with the best compromise between quantification accuracy and simplicity and, second, to assess the impact of CBF changes and radiotracer clearance on SUVRs and noninvasive kinetic modeling data in 18F-florbetaben PET. Methods: Using data from 20 subjects (10 patients with probable Alzheimer dementia and 10 healthy volunteers), the nondisplaceable binding potential (BPND) obtained from the full kinetic analysis was compared with the SUVR and with noninvasive tracer kinetic methods (simplified reference tissue model and multilinear reference tissue model 2). Various approaches using shortened or interrupted acquisitions were compared with the results of the full acquisition (0-140 min). Simulations were performed to assess the effect of CBF and radiotracer clearance changes on SUVRs and noninvasive kinetic modeling outputs. Results: An acquisition protocol using time windows of 0-30 and 120-140 min with appropriate interpolation of the missing time points provided the best compromise between patient comfort and quantification accuracy. Excellent agreement was found between BPND obtained using the full protocol and BPND obtained using the dual-window protocol (for multilinear reference tissue model 2, BPND [dual window] = 0.01 + 1.00.BPND [full], R2 = 0.97; for simplified reference tissue model, BPND [dual-window] = 0.05 + 0.92.BPND [full], R2 = 0.93). Simulations showed a limited impact of CBF and radiotracer clearance changes on multilinear reference tissue model parameters and SUVR. Conclusion: This study demonstrated accurate noninvasive kinetic modeling of 18F-florbetaben PET data using a dual window acquisition, thus providing a good compromise between quantification accuracy, scan duration, and patient burden. The influence of CBF and radiotracer clearance changes on amyloid-beta load estimates was small. For most clinical research applications, the SUVR approach is appropriate. However, for longitudinal studies in which maximum quantification accuracy is desired, this noninvasive dual-window acquisition with kinetic analysis is recommended.

PMID- 29175983 TI - Molecular Imaging of ABCB1 and ABCG2 Inhibition at the Human Blood-Brain Barrier Using Elacridar and 11C-Erlotinib PET. AB - Transporters such as ABCB1 and ABCG2 limit the exposure of several anticancer drugs to the brain, leading to suboptimal treatment in the central nervous system. The purpose of this study was to investigate the effects of the ABCB1 and ABCG2 inhibitor elacridar on brain uptake using 11C-erlotinib PET. Methods: Elacridar and cold erlotinib were administered orally to wild-type (WT) and Abcb1a/b;Abcg2 knockout mice. In addition, brain uptake was measured using 11C erlotinib imaging and ex vivo scintillation counting in knockout and WT mice. Six patients with advanced solid tumors underwent 11C-erlotinib PET scans before and after a 1,000-mg dose of elacridar. 11C-erlotinib brain uptake was quantified by pharmacokinetic modeling using volume of distribution (VT) as the outcome parameter. In addition, 15O-H2O scans to measure cerebral blood flow were acquired before each 11C-erlotinib scan. Results: Brain uptake of 11C-erlotinib was 2.6-fold higher in Abcb1a/b;Abcg2 knockout mice than in WT mice, measured as percentage injected dose per gram of tissue (P = 0.01). In WT mice, the addition of elacridar (at systemic plasma concentrations of >=200 ng/mL) resulted in an increased brain concentration of erlotinib, without affecting erlotinib plasma concentration. In patients, the VT of 11C-erlotinib did not increase after intake of elacridar (0.213 +/- 0.12 vs. 0.205 +/- 0.07, P = 0.91). 15O-H2O PET showed no significant changes in cerebral blood flow. Elacridar exposure in patients was 401 +/- 154 ng/mL. No increase in VT with increased elacridar plasma exposure was found over the 271-619 ng/mL range. Conclusion: When Abcb1 and Abcg2 were disrupted in mice, brain uptake of 11C-erlotinib increased both at a tracer dose and at a pharmacologic dose. In patients, brain uptake of 11C-erlotinib was not higher after administration of elacridar. The more pronounced role that ABCG2 appears to play at the human blood-brain barrier and the lower potency of elacridar to inhibit ABCG2 may be an explanation of these interspecies differences. PMID- 29175984 TI - Model of Intraperitoneal Targeted alpha-Particle Therapy Shows That Posttherapy Cold-Antibody Boost Enhances Microtumor Radiation Dose and Treatable Tumor Sizes. AB - Intraperitoneally administered radiolabeled monoclonal antibodies (mAbs) have been tested in several clinical trials, often with promising results, but have never proven curative. Methods: We have previously presented simulations of clinically relevant amounts of intraperitoneal 90Y-mAbs for treatment of minimal disease and shown that such treatments are unlikely to eradicate microtumors. Our previous model simulated the kinetics of intraperitoneally infused radiolabeled mAbs in humans and showed the benefit of instead using alpha-emitters such as 211At. In the current work, we introduce penetration of mAbs into microtumors with radii of up to 400 MUm. Calculations were performed using dynamic simulation software. To determine the radiation dose distribution in nonvascularized microtumors of various sizes after intraperitoneal 211At-radioimmunotherapy, we used an in-house-developed Monte Carlo program for microdosimetry. Our aim was to find methods that optimize the therapy for as wide a tumor size range as possible. Results: Our results show that high-specific-activity radiolabeled mAbs that are bound to a tumor surface will penetrate slowly compared with the half lives of 211At and shorter-lived radionuclides. The inner-core cells of tumors with radii exceeding 100 MUm may therefore not be sufficiently irradiated. For lower specific activities, the penetration rate and dose distribution will be more favorable for such tumors, but the dose to smaller microtumors and single cells will be low. Conclusion: Our calculations show that the addition of a boost with unlabeled mAb 1-5 h after therapy results in sufficient absorbed doses both to single cells and throughout microtumors up to approximately 300 MUm in radius. This finding should also hold for other high-affinity mAbs and short-lived alpha emitters. PMID- 29175985 TI - Care bundles to reduce central line-associated bloodstream infections in the neonatal unit: a systematic review and meta-analysis. AB - BACKGROUND: Central line-associated bloodstream infections (CLABSIs) are associated with increased mortality, prolonged hospitalisation and increased healthcare costs. Care bundles have reduced CLABSIs in adult intensive care units (ICUs) but replication in paediatric ICUs has had inconsistent outcomes. A systematic review was performed to assess the evidence for the efficacy of care bundles in reducing CLABSIs in the neonatal unit (NNU). METHODS: MEDLINE, CINAHL and EMBASE were searched from January 2010 up to January 2017. The Cochrane Library, Web of Science, Zetoc and Ethos were searched for additional studies. Randomised controlled trials (RCTs), quasi-experimental and observational studies were eligible. The primary outcome measure was CLABSI rates per 1000 central line, or patient, days. A meta-analysis was performed using random effects modelling. RESULTS: Twenty-four studies were eligible for inclusion: six were performed in Europe, 12 were in North America, two in Australia and four were in low/middle-income countries. Five were observational studies and 19 were before and after quality improvement studies. No RCTs were found. Meta-analysis revealed a statistically significant reduction in CLABSIs following the introduction of care bundles (rate ratio=0.40 (CI 0.31 to 0.51), p<0.00001), which equates to a 60% reduction in CLABSI rate. CONCLUSION: There is a substantial body of quasi experimental evidence to suggest that care bundles may reduce CLABSI rates in the NNU, though it is not clear which bundle elements are effective in specific settings. Future research should focus on determining what processes promote the effective implementation of infection prevention recommendations, and which elements represent essential components of such care bundles. PMID- 29175986 TI - Partial oxidation of alkanes by dioxiranes formed in situ at low temperature. AB - Partial oxidation catalysts capable of efficiently operating at low temperatures may limit the over-oxidation of alkane substrates and thereby improve selectivity. This work focuses on examining alkane oxidation using completely metal-free organocatalysts, dioxiranes. The dioxiranes employed here are synthesized by oxidation of a ketone using a terminal oxidant, such as hydrogen peroxide. Our work generates the dioxirane in situ, so that the process can be catalytic with respect to the ketone. To date, we have demonstrated selective partial oxidation of adamantane using ketone catalysts resulting in yields upwards of 60% towards 1-adamantanol with greater than 99% selectivity. Furthermore, we have demonstrated that changing the electrophilic character of the ketone R groups to contain more electron-donating ligands facilitates the dioxirane ring formation and improves overall oxidation yields. Isotopic labelling studies using H218O2 show the preferential incorporation of an 18O label into the parent ketone, providing evidence for a dioxirane intermediate formed in situ The isotopic labelling studies, along with solvent effect studies, suggest the formation of peracetic acid as a reactive intermediate.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'.

PMID- 29175989 TI - 3-(Bromomethyl)-2-chloro-4-(methylsulfonyl)- benzoic acid: a new cause of sensitiser induced occupational asthma, rhinitis and urticaria. AB - OBJECTIVES: 3-(Bromomethyl)-2-chloro-4-(methylsulfonyl)-benzoic acid (BCMBA) has not previously been identified as a respiratory sensitiser. We detected two cases who presented respiratory and urticaria symptoms related to BCMBA and had positive skin prick tests to the agent. Subsequently, we conducted outbreak investigations at the BCMBA-producing factory and performed clinical examinations to confirm occupational diseases. METHODS: The outbreak investigations included observations of work processes, assessment of exposure, a medical survey with a questionnaire and skin prick tests with 0.5% BCMBA water solution on 85 exposed workers and 9 unexposed workers. We used specific inhalation or nasal challenge and open skin application test to investigate BCMBA-related occupational asthma, rhinitis and contact urticaria. RESULTS: We identified nine workers with respiratory and/or skin symptoms and positive skin prick tests to BCMBA in a chemical factory. A survey among chemical factory workers indicated a BCMBA related sensitisation rate of 8% among all exposed workers; the rate was highest (25%) among production workers in the production hall. Sensitisation was detected only in workers with the estimated highest exposure levels. Six cases of occupational asthma, rhinitis and/or contact urticaria caused by BCMBA were confirmed with challenge tests. Asthma-provoking doses in specific inhalation challenges were very low (0.03% or 0.3% BCMBA in lactose). CONCLUSIONS: We identified a new low molecular weight agent causing occupational asthma, rhinitis and contact urticaria. A typical clinical picture of allergic diseases and positive skin prick tests suggest underlying IgE-mediated disease mechanisms. Stringent exposure control measures are needed in order to prevent BCMBA-related diseases. PMID- 29175990 TI - Prevalence of occupational exposure to asthmagens derived from animals, fish and/or shellfish among Australian workers. AB - OBJECTIVE: Several animal, fish and/or shellfish derived substances encountered in the workplace can initiate or exacerbate asthma. The aims of this study were: to produce a population-based estimate of the current prevalence of occupational exposure to animal, fish and/or shellfish derived asthmagens, to identify the main circumstances of exposures and to identify occupations with the highest proportions of exposed respondents. METHODS: We used data from the Australian Work Exposure Study-Asthma, a national telephone survey that investigated the current prevalence of occupational exposure to asthmagens among Australian workers. A web-based tool was used to collect job task information and assign exposure to asthmagens, including animal, fish and/or shellfish derived asthmagens. Prevalence ratios to determine risk factors for exposure were estimated using modified Poisson regression. RESULTS: Of the 4878 respondents, 12.4% were exposed to asthmagens derived from animals, fish and/or shellfish. Exposure to these asthmagens was significantly higher in workers residing in regional and remote areas, compared with major cities. The main circumstance of exposure to animal derived asthmagens was through cleaning up rat/mice infestations, while the main circumstance of exposure to fish and/or shellfish derived asthmagens was through preparing and cooking salmon. Occupational groups with the highest proportion of exposure to animal or fish and/or shellfish derived asthmagens were farmers/animal workers and food workers, respectively. CONCLUSIONS: This is the first study investigating occupational exposure to animal, fish and/or shellfish derived asthmagens in a nationwide working population. The results of this study can be used to inform the direction of occupational interventions and policies to reduce work-related asthma. PMID- 29175991 TI - Nurse education in sexual health.

PMID- 29175999 TI - Modern fertility awareness methods: wrist wearables capture the changes in temperature associated with the menstrual cycle. AB - Core and peripheral body temperatures are affected by changes in reproductive hormones during the menstrual cycle. Women worldwide use the basal body temperature (BBT) method to aid and prevent conception. However, prior research suggests that taking one's daily temperature can prove inconvenient and subject to environmental factors. We investigate whether a more automatic, non-invasive temperature measurement system can detect changes in temperature across the menstrual cycle. We examined how wrist skin temperature (WST), measured with wearable sensors, correlates with urinary tests of ovulation and may serve as a new method of fertility tracking. One hundred and thirty-six eumenorrheic, non pregnant women participated in an observational study. Participants wore WST biosensors during sleep and reported their daily activities. An at-home luteinizing hormone (LH) test was used to confirm ovulation. WST was recorded across 437 cycles (mean cycles/participant = 3.21, S.D. = 2.25). We tested the relationship between the fertile window and WST temperature shifts, using the BBT three-over-six rule. A sustained 3-day temperature shift was observed in 357/437 cycles (82%), with the lowest cycle temperature occurring in the fertile window 41% of the time. Most temporal shifts (307/357, 86%) occurred on ovulation day (OV) or later. The average early-luteal phase temperature was 0.33 degrees C higher than in the fertile window. Menstrual cycle changes in WST were impervious to lifestyle factors, like having sex, alcohol, or eating prior to bed, that, in prior work, have been shown to obfuscate BBT readings. Although currently costlier than BBT, the present study suggests that WST could be a promising, convenient parameter for future multiparameter fertility awareness methods. PMID- 29175997 TI - Up-regulated miR-500a enhances hepatocarcinoma metastasis by repressing PTEN expression. AB - It has been shown that miR-500a may play an important role in the metastasis of hepatocarcinoma. The present study is to explore the influence of miR-500a on hepatocarcinoma proliferation and metastasis, and the related molecular mechanism. The levels of miR-500a in the serum and tissues of patients with metastatic or non-metastatic hepatocarcinoma or normal people were determined by quantitative reverse transcription-PCR (qRT-PCR). The proliferation, invasion, and cloning of hepatocarcinoma cell lines SMMC-7721 after transfection with mimic miR-500a or inhibitor miR-500a were determined. Luciferase reported assay was used to explore the relationship between miR-500a and phosphatase and tensin homologue (PTEN). Then, the protein expression of PTEN, p-Akt (S473), p-Akt (T308), Akt, p-mTOR, mTOR, p-4E-BP1, 4E-BP1, p-S6K, and S6K in SMMC-7721 cells were also determined by Western blotting. The expression of miR-500a in patients with metastatic hepatocarcinoma was significantly higher than the non-metastatic hepatocarcinoma. Overexpression of miR-500a promoted the proliferation, invasion, and cloning of SMMC-7721 cells. Luciferase reported assay showed miR-500a could directly target at 3'-UTR of PTEN. Overexpression of miR-500a significantly reduced the expression of PTEN, and enhanced phosphorylation of Akt, mTOR, S6K, and 4E-BP1. In conclusion, the expression of miR-500a was related to the proliferation and metastasis of hepatocarcinoma, which may be partly because of the activation of AKT/mTOR pathway through targetting PTEN. PMID- 29175998 TI - Structural determinants for protein unfolding and translocation by the Hsp104 protein disaggregase. AB - The ring-forming Hsp104 ATPase cooperates with Hsp70 and Hsp40 molecular chaperones to rescue stress-damaged proteins from both amorphous and amyloid forming aggregates. The ability to do so relies upon pore loops present in the first ATP-binding domain (AAA-1; loop-1 and loop-2 ) and in the second ATP binding domain (AAA-2; loop-3) of Hsp104, which face the protein translocating channel and couple ATP-driven changes in pore loop conformation to substrate translocation. A hallmark of loop-1 and loop-3 is an invariable and mutational sensitive aromatic amino acid (Tyr257 and Tyr662) involved in substrate binding. However, the role of conserved aliphatic residues (Lys256, Lys258, and Val663) flanking the pore loop tyrosines, and the function of loop-2 in protein disaggregation has not been investigated. Here we present the crystal structure of an N-terminal fragment of Saccharomyces cerevisiae Hsp104 exhibiting molecular interactions involving both AAA-1 pore loops, which resemble contacts with bound substrate. Corroborated by biochemical experiments and functional studies in yeast, we show that aliphatic residues flanking Tyr257 and Tyr662 are equally important for substrate interaction, and abolish Hsp104 function when mutated to glycine. Unexpectedly, we find that loop-2 is sensitive to aspartate substitutions that impair Hsp104 function and abolish protein disaggregation when loop-2 is replaced by four aspartate residues. Our observations suggest that Hsp104 pore loops have non-overlapping functions in protein disaggregation and together coordinate substrate binding, unfolding, and translocation through the Hsp104 hexamer.

PMID- 29176000 TI - Effects of GABAB receptor activation on spatial cognitive function and hippocampal neurones in rat models of type 2 diabetes mellitus. AB - The present study was conducted with the aim being to investigate the effect gamma-aminobutyric acid type B (GABAB) receptor activation have on spatial cognitive function and hippocampal neurones found in the rat models of type 2 diabetes mellitus (T2DM). T2DM rat models were then established, randomized, and subsequently assigned into normal control (NC), T2DM, T2DM + chemical grade propylene (CGP), T2DM + baclofen, and T2DM + CGP + baclofen groups. T2DM rats' weight and blood sugar concentrations were monitored. The DMS-2 Morris water maze testing system was performed in order to figure out the spatial cognitive function of these rats. Reverse-transcription quantitative PCR (RT-qPCR) and Western blotting were also performed in order to detect GABAB mRNA and protein expressions. We used the Nissl staining method in order to detect the number of hippocampal neurones, TUNEL (terminal deoxyribonucleotidy transferase-mediated dUTP nick labeling) staining to detect cell apoptosis, and Western blotting method in order to measure the expressions of the apoptosis-related proteins (Bax, cytochrome c (Cyt-c), Caspase-3, and Bcl-2). In comparison with the T2DM group, the weight decreased, blood sugar concentration increased, and spatial cognitive function as well as hippocampal neurones were both impaired in the T2DM + CGP group, contrary to the rats in the T2DM + baclofen group who showed an opposite trend. The situation in the T2DM + CGP + baclofen group was better than that found in the T2DM + CGP group while proving to be more serious than that of the NC and T2DM + baclofen groups. Conclusively, activating the GABAB receptor improved spatial cognitive function and hippocampal neurones in the T2DM rats. PMID- 29176002 TI - Physiological monitoring for healthy military personnel. AB - Military employment commonly exposes personnel to strenuous physical exertion. The resulting interaction between occupational stress and individual susceptibility to illness demands careful management. This could extend to prospective identification of high physiological strain in healthy personnel, in addition to recognition and protection of vulnerable individuals. The emergence and ubiquitous uptake of 'wearable' physiological and medical monitoring devices might help to address this challenge, but requires that the right questions are asked in sourcing, developing, validating and applying such technologies. Issues that must be addressed include system requirements, such as the likelihood of end users deploying and using technology as intended; interpretation of data in relation to pretest probability, including the potential for false-positive results; differentiation of pathological states from normal physiology; responsibility for and consequences of acting on abnormal or unexpected results and cost-effectiveness. Ultimately, the performance of a single monitoring system, in isolation or alongside other measures, should be judged by whether any improvement is offered versus existing capabilities and at what cost to mission effectiveness. PMID- 29176003 TI - Predicting how health behaviours contribute to the development of diseases within a military population in the Hungarian Defence Forces. AB - INTRODUCTION: Recent legislative amendments in Hungary have resulted in the possibility for early retirement being abolished in the Hungarian Defence Forces. The retirement age for professional soldiers has also increased to 65 years, thereby greatly increasing the average length of military service. This necessitates greater attention to the health and care of service personnel due to the increase of chronic non-communicable diseases with age. The aim of this research was to identify how health behaviours might potentially contribute to diseases in the Hungarian Defence Forces. METHODS: All members of the Hungarian Defence Forces undergoing health screenings between 2011 and 2015 were assessed. Health variables analysed were derived from the health screening data sheet which is collected from every member of the Hungarian Defence Forces undergoing a health screening since 2009. Items recorded were connected to health behaviour (physical activity, nutrition, smoking), subjective well-being (psychosomatic backache, fatigue and quality of waking up to describe the quality of sleep), sociodemographic data (age, gender) and the mental toughness quotient (MTQ). A logistic regression model was utilised to predict how health behaviour may affect the development of disease. RESULTS: Factors most associated with the development of disease included psychosomatic backache (P<0.000), age (P<0.001), frequency of undertaking sports (P<0.05), quality of sleeping and waking up (P<0.05) and the assessment of gender differences (P<0.05). CONCLUSIONS: Extension of the length of active service will result in an increased burden of disease for members of the Hungarian Defence Forces. This includes both physical and psychological morbidity that could potentially be obstacles for service personnel to perform their military duties. Health behaviours such as psychosomatic backache, the frequency of performing sports and sleep quality may predict the development of disease and should be explored in health screening consultations. PMID- 29176004 TI - Musculoskeletal injuries in British Army recruits: a prospective study of incidence in different Infantry Regiments. AB - BACKGROUND: Musculoskeletal injuries and attrition incurred during basic military training are a significant socioeconomic burden across many Defence Forces. In order to plan an injury prevention strategy, the purpose of this study was to quantify the regiment-specific musculoskeletal injury patterns and training outcomes. METHODS: This was a prospective observational study of the Parachute (n=734), Guards (n=1044), Line (n=3472) and Gurkha (n=458) Regiments of the British Army recruits during a 26-week basic military training programme over a 2 year period. The participant demographic characteristics were: age 18.9 years (SD+/-2.3), height 176.5 cm (SD+/-7.80), mass 69 kg (SD+/-9.7) and body mass index 22.14 kg/m2 (SD+/-2.5). RESULTS: The incidence of injuries (86%, 46%, 48% and 10%) was significantly different (p<0.001) as were the first time pass out rates (p=0.02) of 38%, 51%, 56% and 98% for Parachute, Guards, Line and Gurkha, respectively. Overuse injuries were more frequently reported than both acute and recurrent injuries in all regiments (X2=688.01, p<0.01). CONCLUSIONS: The disparity in injury incidence and training outcome between Infantry Regiments suggests that the demands of training be taken into account when devising injury prevention strategies. PMID- 29176005 TI - Could routine spirometry suggest sensitisation in the military medicine setting? AB - INTRODUCTION: Providing evidence of sensitisation is the formal requirement for allergy diagnosis. The aim of this study was to evaluate whether spirometry may be able to predict sensitisation in a representative cohort of Italian Navy military personnel. METHODS: 2043 (1875 men, 168 women, mean age 28.35+/-11.6 years) Italian Navy military personnel were enrolled into this study. Spirometry and skin prick testing were performed to predict sensitisation. RESULTS: Sensitisation, assessed by skin prick test, was documented in 658 (32.2%) subjects. Impaired forced expiratory flow at the 25% and 75% of the pulmonary volume (FEF25-75) as demonstrated on spirometry was detected in 82 subjects, of whom 69 were sensitised (P<0.0001). Impaired FEF25-75 was significantly associated with sensitisation (OR 7.43; 95% CI 4.04 to 14.66; P<0.0001). DISCUSSION: The findings of this study suggest that impaired FEF25-75 may predict sensitisation in this cohort of Italian Navy personnel. This outcome is relevant in the military medical setting, as it could allow early identification of subjects with subclinical asthma. PMID- 29176006 TI - GPR120: Mechanism of action, role and potential for medical applications. AB - G protein-coupled receptors (GPCRs) constitute a family of transmembrane proteins that mediate many cellular processes. GPR120/FFAR4, a receptor from this family that is activated by fatty acids, has received considerable attention recently. This paper presents a literature review concerning the role of GPR120 and its mechanism of action in animal and human studies as well as the potential use of GPR120 for the treatment of chronic diseases. Two electronic databases - Medline and Google Scholar - were searched for available studies addressing the review topic that were written in English and published from 2000 to June 2017. The following key terms were used in the search: GPR120, FFA4, GPR120 agonist, PUFAs, EPA, DHA, adipocyte, obesity, hyperlipidemia, inflammation, cancer, diabetes, insulin resistance, taste, atherogenesis, hepatis, central nervous system. In humans, GPR120 expression is expressed in macrophages, eosinophils, and adipose tissue, in cells of the tongue, liver, lungs, small and large intestine, gastric mucosa, and pancreas, in the central nervous system and placental microvilli. Medium- and long-chain fatty acids act as ligands for the receptor. Through the internalization of beta-arrestin-2 complex and the inhibition of NF-kappaB, GPR120 mediates the activation of the cell's anti-inflammatory mechanisms. The receptor is also involved in the maturation of adipocytes, the modulation of insulin signalling pathways, the regulation of glucose metabolism, and the secretion of intestinal hormones. GPR120 is a promising target for the treatment of numerous diseases, whose pathophysiology is associated with low-grade inflammation. As a result of intensive searches, a likely group of synthetic agonists of the receptor was determined with potential therapeutic applications in conditions such as obesity, impaired carbohydrate metabolism, inflammatory bowel diseases, cancer, mental disorders. PMID- 29176007 TI - Between biology and medicine: perspectives on the use of dendritic cells in anticancer therapy. AB - Dendritic cells (DCs), as a link between innate and adaptive immunity, play a pivotal role in maintaining homeostasis of the immune system. The DC population is characterized by heterogeneity; it consists of many subpopulations which, despite their phenotypic and localization differences, play an essential function - they are professional antigen presenting cells. Due to their role, DCs can be utilized in a new cancer treatment strategy. Their main purpose is to generate an anticancer response leading to the elimination of cancer cells. The tumor microenvironment, abundant in immunosuppressive factors (e.g. IL-10, TGF-beta, Arg1, IDO), impairs the proper function of DCs. For this reason, various strategies are necessary for ex vivo preparation of DC-based vaccines and for the support of in vivo DCs to fight against tumors. DC-based vaccines are combined with other forms of immunotherapy (e.g. blockade of immune checkpoint molecules, e.g. PD-1 or CTLA-4) or conventional types of therapies (e.g. chemotherapy). Despite the enormous progress that has been made in anticancer therapy in the past two decades, there are still many unresolved issues regarding the effectiveness of the DCs usage. In this paper we described, in both a mouse and a human subject, a series of DC subpopulations, differentiating in normal conditions or under the influence of cancer microenvironment. We listed factors affecting the quality of the in vivo and ex vivo generations of antitumoral responses, significant from a therapeutic point of view. Moreover, the most important strategies for the use of DCs in anticancer therapies, as well as further developments on this field, have been discussed. PMID- 29176008 TI - Viability and growth promotion of starter and probiotic bacteria in yogurt supplemented with whey protein hydrolysate during refrigerated storage. AB - The effect of whey protein hydrolysate (WPH) addition on growth of standard yoghurt cultures and Bifidobacterium adolescentis during co-fermentation and its viability during storage at 4oC in yoghurts has been evaluated. WPH was obtained with the use of serine protease from Y. lipolytica yeast. Stirred probiotic yoghurts were prepared by using whole milk standardized to 16% of dry matter with the addition of either whey protein concentrate, skim milk powder (SMP), WPH-SMP (ratio 1:1), WPH. The hydrolysate increased the yoghurt culture counts at the initial stage of fermentation and significantly inhibited the decrease in population viability throughout the storage at 4oC in comparison to the control. The post-fermentation acidification was also retarded by the addition of WPH. The hydrolysate did not increase the Bifidobacterium adolescentis counts at the initial stage. However, the WPH significantly improved its viability. After 21 days of storage, in the yogurts supplemented with WPH, the population of these bacteria oscillated around 3.04 log10 CFU/g, while in samples where SMP or whey protein concentrate was used, the bacteria were no longer detected.

AB - BACKGROUND: Customer satisfaction is a key quality indicator of laboratory service. Patients and physicians are the ultimate customers in medical laboratory, and their opinions are essential components in developing a customer oriented laboratory. METHODS: A longitudinal investigation of customer satisfaction was conducted through questionnaires. We designed two different questionnaires and selected 1200 customers (600 outpatients and 600 physicians) to assess customer satisfaction every other year from 2012 to 2016. Items with scores <4 were considered unsatisfactory, and corrective actions should be taken. RESULTS: The completion rates of physicians were 96.8% in 2012, 97% in 2014 and 96.5% in 2016, whereas the rates of patients were 95.3%, 96.2% and 95.2%, respectively. In 2012, the most dissatisfaction items were test turnaround time (3.77 points) and service attitude (3.87 points) from physicians, whereas waiting time (3.58 points) and examination environment (3.64 points) were the most dissatisfaction items from patients. After corrective actions were taken, the result of satisfaction in 2014 was better, which illustrated our strategy was effective. However, some items remained to be less than 4, so we repeated the survey after modifying questionnaires in 2016. However, the general satisfaction points of the physicians and patients reduced in 2016, which reminded us of some influential factors we had neglected. CONCLUSIONS: By using dynamic survey of satisfaction, we can continuously find deficiencies in our laboratory services and take suitable corrective actions, thereby improving our service quality. PMID- 29176011 TI - Estimation of fractions metabolized by hepatic CYP enzymes using a concept of inter-system extrapolation factors (ISEFs) - a comparison with the chemical inhibition method. AB - BACKGROUND: For estimation of fractions metabolized (fm) by different hepatic recombinant human CYP enzymes (rhCYP), calculation of inter-system extrapolation factors (ISEFs) has been proposed. METHODS: ISEF values for CYP1A2, CYP2C19 and CYP3A4/5 were measured. A CYP2C9 ISEF was taken from a previous report. Using a set of compounds, fractions metabolized by CYP enzymes (fm,CYP) values calculated with the ISEFs based on rhCYP data were compared with those from the chemical inhibition data. Oral pharmacokinetics (PK) profiles of midazolam were simulated using the physiologically based pharmacokinetics (PBPK) model with the CYP3A ISEF. For other CYPs, the in vitro fm,CYP values were compared with the reference fm,CYP data back-calculated with, e.g. modeling of test substrates by feeding clinical PK data. RESULTS: In vitro-in vitro fm,CYP3A4 relationship between the results from rhCYP incubation and chemical inhibition was drawn as an exponential correlation with R2=0.974. A midazolam PBPK model with the CYP3A4/5 ISEFs simulated the PK profiles within twofold error compared to the clinical observations. In a limited number of cases, the in vitro methods could not show good performance in predicting fm,CYP1A2, fm,CYP2C9 and fm,CYP2C19 values as reference data. CONCLUSIONS: The rhCYP data with the measured ISEFs provided reasonable calculation of fm,CYP3A4 values, showing slight over-estimation compared to chemical inhibition. PMID- 29176012 TI - Sirolimus therapy for congenital hyperinsulinism in an infant with a novel homozygous KCNJ11 mutation. AB - BACKGROUND: Congenital hyperinsulinism results in refractory hypoglycemia. If a therapy with diazoxide has been unresponsive this has been treated by subtotal pancreatectomy in the past. This therapeutic option poses an increased risk of developing diabetes at a later stage. There have been a few case reports on the use of sirolimus in such situations in the recent past. CASE PRESENTATION: Our patient was started on sirolimus very early, on day 29 of life and at the age of 14 months is doing well on sirolimus therapy. His growth and development have been good and he has not had any major complications so far. Genetic testing showed a novel KCNJ11 homozygous mutation on next generation sequencing and the parents were heterozygous carriers. CONCLUSIONS: We report the successful use of sirolimus in the management of diazoxide unresponsive congenital hyperinsulinism with diffuse pancreatic involvement. We believe this is the youngest patient to be initiated on sirolimus so far. PMID- 29176013 TI - Transfusion-associated necrotizing enterocolitis in preterm infants: an updated meta-analysis of observational data. AB - BACKGROUND: The number of observational studies that report an association between packed red blood cell (PRBC) transfusions and necrotizing enterocolitis (NEC) has increased. The primary objective of this study was to evaluate the association between PRBC transfusions and NEC in observational studies. METHODS: Medline, Embase and Cochrane Library databases as well as the Pediatrics Academic Societies abstract archives were systematically searched to identify observational studies that investigated the association between PRBC transfusions and NEC. Key search terms included premature infant, blood transfusion and necrotizing enterocolitis. The generic inverse variance method with a random effects model was used to meta-analyze selected studies. Odds ratios (ORs) and confidence intervals (CIs) were calculated. RESULTS: A meta-analysis of 17 observational studies that reported the association between PRBC transfusions and NEC was performed. The meta-analysis revealed no evidence of an association between PRBC transfusions and a higher risk of NEC (OR: 0.96; 95% CI: 0.53-1.71; P=0.88). The effect estimates that suggested an association between PRBC transfusion and NEC in matched case-control studies (OR: 1.20; 95% CI: 0.58-2.47; P=0.63) differed from those reported in cohort studies (OR: 0.51; 95% CI: 0.34 0.75; P=<0.01). CONCLUSIONS: This updated meta-analysis of predominantly low-to moderate quality observational studies suggests that there is no significant association between PRBC transfusions and NEC. A higher quality of evidence on this topic is needed.

PMID- 29176015 TI - Determination of age- and sex-specific 99th percentiles for high-sensitive troponin T from patients: an analytical imprecision- and partitioning-based approach. AB - BACKGROUND: Detection of acute myocardial infarction (AMI) is mainly based on a rise of cardiac troponin with at least one value above the 99th percentile upper reference limit (99th URL). However, circulating high-sensitive cardiac troponin T (hs-cTnT) concentrations depend on age, sex and renal function. Using an analytical imprecision-based approach, we aimed to determine age- and sex specific hs-cTnT 99th URLs for patients without chronic kidney disease (CKD). METHODS: A 3.8-year retrospective analysis of a hospital laboratory database allowed the selection of adult patients with concomitant plasma hs-cTnT (<300 ng/L) and creatinine concentrations, both assayed twice within 72 h with at least 3 h between measurements. Absence of AMI was assumed when the variation between serial hs-cTnT values was below the adjusted-analytical change limit calculated according to the inverse polynomial regression of analytical imprecision. Specific URLs were determined using Clinical and Laboratory Standards Institute (CLSI) methods, and partitioning was tested using the proportion method, after adjustment for unequal prevalences. RESULTS: After outlier removal (men: 8.7%; women: 6.6%), 1414 men and 1082 women with estimated glomerular filtration rate (eGFR) >=60 mL/min/1.73 m2 were assumed as non-AMI. Partitioning into age groups of 18-50, 51-70 and 71-98 years, the hs-cTnT 99th URLs adjusted on French prevalence were 18, 33, 66 and 16, 30, 84 ng/L for men and women, respectively. Age-partitioning was clearly required. However, sex-partitioning was not justified for subjects aged 18-50 and 51-70 years for whom a common hs-cTnT 99th URLs of about 17 and 31 ng/L could be used. CONCLUSIONS: Based on a laboratory approach, this study supports the need for age-specific hs-cTnT 99th URLs.

PMID- 29176016 TI - Proficiency testing program for hemoglobin E, A2 and F analysis in Thailand using lyophilized hemoglobin control materials. AB - BACKGROUND: There is no external quality assessment (EQA) program for hemoglobin analysis that uses lyophilized hemoglobin control materials with HbA2/E in levels as high as those found in people with the beta-thalassemia trait, HbE trait, beta thalassemia/HbE disease or homozygous HbE; these are all found frequently in the southeast Asian population. The aim of this study was to evaluate the efficiency of the control materials used in the established proficiency testing (PT) program at the Associated Medical Sciences-Clinical Service Center (AMC-CSC), Chiang Mai University, Chiang Mai, Thailand. METHODS: The PT program for Hb analysis and the thalassemia interpretation was established in compliance with ISO/IEC17043:2010. Three cycles per year were performed in 2015 and 2016. In each cycle, three different types of control material were provided to the participants. Each participant analyzed the control materials in the same manner as in their routine practices. Hb analysis results and their thalassemia interpretation codes were entered into the report form and sent back to AMC-CSC. RESULTS: The number of participants increased from 63 in 2015 to 76 in 2016. In addition, the number of participants who took part in all three cycles increased from 95.2% (60/63) in 2015 to 100% (76/76) in 2016. All participants reported the correct Hb measurement and type; however, misinterpretations in thalassemia diagnosis were noted. CONCLUSIONS: The lyophilized hemoglobin control materials prepared at AMC CSC were used successfully in our PT program. However, the study results indicate the need for further improvement in thalassemia interpretation skills for laboratory staff. PMID- 29176018 TI - Diagnostic and prognostic value of presepsin vs. established biomarkers in critically ill patients with sepsis or systemic inflammatory response syndrome. AB - BACKGROUND: Inflammatory biomarkers may aid to distinguish between systemic inflammatory response syndrome (SIRS) vs. sepsis. We tested the hypotheses that (1) presepsin, a novel biomarker, can distinguish between SIRS and sepsis, and (2) higher presepsin levels will be associated with increased severity of illness and (3) with 28-day mortality, outperforming traditional biomarkers. METHODS: Procalcitonin (PCT), C-reactive protein (CRP), presepsin, and lactate were analyzed in 60 consecutive patients (sepsis and SIRS, n=30 per group) on day 1 (D1) to D3 (onset sepsis, or after cardiac surgery). The systemic organ failure assessment (SOFA) score was determined daily. RESULTS: There was no difference in mortality in sepsis vs. SIRS (12/30 vs. 8/30). Patients with sepsis had higher SOFA score vs. patients with SIRS (11+/-4 vs. 8+/-5; p=0.023), higher presepsin (AUC=0.674; p<0.021), PCT (AUC=0.791; p<0.001), CRP (AUC=0.903; p<0.0001), but not lactate (AUC=0.506; p=0.941). Unlike other biomarkers, presepsin did not correlate with SOFA on D1. All biomarkers were associated with mortality on D1: presepsin (AUC=0.734; p=0.0006; best cutoff=1843 pg/mL), PCT (AUC=0.844; p<0.0001), CRP (AUC=0.701; p=0.0048), and lactate (AUC=0.778; p<0.0001). Multiple regression analyses showed independent associations of CRP with diagnosis of sepsis, and CRP and lactate with mortality. Increased neutrophils (p=0.002) and decreased lymphocytes (p=0.007) and monocytes (p=0.046) were also associated with mortality. CONCLUSIONS: Presepsin did not outperform traditional sepsis biomarkers in diagnosing sepsis from SIRS and in prognostication of mortality in critically ill patients. Presepsin may have a limited adjunct value for both diagnosis and an early risk stratification, performing independently of clinical illness severity. PMID- 29176019 TI - In vitro modulation of the cytochrome P450 and ABCB1/P-glycoprotein activities of the aqueous extract of Allophylus cominia (L) Sw. leaves. AB - BACKGROUND: The aqueous extract of the Allophylus cominia (L) Sw (Sapindaceae) leaves has shown anti-diabetic, anti-obesity and anti-inflammatory properties. In the Caribbean region, it is typically used for the treatment of type-2 diabetes. METHODS: Considering the herb-drug interaction, the aim of this study was to evaluate the potential effects of the A. cominia extract on the cytochrome P450 (CYP) (rat hepatocyte model) and P-glycoprotein (P-gp) (4T1 cell line) systems. RESULTS: The extract did not decrease the cell viability after being assayed by the MTT test at up to 1500 MUg/mL for 72 h. The exposure of the cultured rat hepatocytes to the product (up to 250 MUg/mL) for 48 h increased the activities of CYP-1A2, 2C9, and 2E1 by 1.46-, 1.60-, and 1.51-fold, respectively, compared with the controls. The activities of CYP-2B6, 2D6, and 3A4 were not significantly altered, whereas the activity of P-gp decreased by 2- and 4-fold. In addition, the extracts at 100 and 200 MUg/mL significantly increased doxorubicin cytotoxicity in these cells 24 h after treatment. CONCLUSIONS: The findings indicate that the A. cominia extract modulates the CYP and P-gp systems increasing sensitivity to doxorubicin. Further studies are necessary to evaluate the potential herb-drug interaction or chemosensitive properties. PMID- 29176020 TI - Antidiarrheal and antimicrobial activities of the ethanol extract from the Icacina senegalensis root bark. AB - BACKGROUND: The Icacina senegalensis root bark is traditionally used for the treatment of gastrointestinal disorders in Nigeria. To date, no scientific study has substantiated or refuted this claim. METHODS: The antidiarrheal and antimicrobial activities of the ethanol root bark extract were investigated in rats and against some selected diarrhea-causing microorganisms. RESULTS: The extract significantly decreased the frequency of castor oil-induced diarrhea, and inhibited the masses and volumes of intestinal fluid accumulation in the castor oil-induced enteropooling method. The distance travelled by the charcoal meal was also decreased by the extract gastrointestinal transit method. The extract also strongly inhibited the growth of some selected microorganisms. CONCLUSIONS: The ethanol extract of the I. senegalensis root bark showed antidiarrheal activity, thus justifying its long folkloric use in diarrhea treatment. The extract also demonstrated antimicrobial activity against selected diarrheal causing organisms. PMID- 29176021 TI - Efficacy and safety of percutaneous administration of dihydrotestosterone in children of different genetic backgrounds with micropenis. AB - BACKGROUND: Exogenous androgen supplement is an optional treatment for micropenis; however, its use in childhood is controversial due to potential side effects. METHODS: Twenty-three children (mean age: 4.07+/-3.4 years) with micropenis of unknown causes harboring the 46,XY karyotype were recruited in an open prospective study. Androgen receptor (AR), steroid 5alpha-reductase-2 (SRD5A2), and SRY genes were sequenced; 2.5% dihydrotestosterone (DHT) transdermal gel (0.1-0.3 mg/kg/day) was applied and titrated within the normal DHT serum reference ranges. Stretched penile length (SPL) was measured before therapy, and after 1, 3 and 6 months of DHT gel treatment, respectively. RESULTS: Two patients were found with AR gene mutations and five patients with SRD5A2 gene mutations. Average stretched penile lengths (SPLs) were 1.68+/-0.6 cm at baseline and 2.2+/-0.66 cm, 2.6+/-0.59 cm and 2.9+/-0.55 cm (mean +/- 1 SD) after 1, 3 and 6 months of treatment, respectively. Fourteen cases (61%) reached standard penile length ranges (>-2.5 SD) and medication was discontinued; six cases (26%) were satisfied with the improved penile lengths despite failing to reach the aged matched standards. Three infants (13%) discontinued the medication after 3 months due to anxiety about the potential side effects. No significant side effects were found except the elevated DHT serum levels after therapy. CONCLUSIONS: Short term and local application of DHT at low doses in patients with micropenis could accelerate penile growth effectively without evident side effects; however, precautions still need be taken due to the paucity of long term study and the lack of ideal DHT dosage. PMID- 29176022 TI - Mutation analysis of the phenylalanine hydroxylase gene and prenatal diagnosis of phenylketonuria in Shaanxi, China. AB - BACKGROUND: This study aims to investigate the spectrum and frequency of phenylalanine hydroxylase (PAH) gene mutations and the power to prenatally diagnose phenylketonuria (PKU) patients in Shaanxi, China. METHODS: Polymerase chain reaction (PCR) and DNA sequencing analyses were performed to examine the PAH gene in 33 PKU patients and seven amniotic fluid samples. Thirty-four pathogenic variants were indicated in all 63 alleles, in which two probands carried three variants. RESULTS: Pedigree analysis suggested that the [c.158G>A([p.R53H)][IVS7+2T>A] mutation was located at the same chromatid. However, there was a controversial viewpoint that thought the c.158G>A(p.R53H) variant was a polymorphism in the Chinese. We also found one novel indel mutation and identified the c.59_60delAGinsCC mutation of the PAH gene for the very first time. The spectrum of the PAH mutations in Shaanxi Province were similar to that among China's population. Based on the results of PAH gene analysis, we further performed prenatal genetic diagnoses for seven PKU families. All foetuses were definitively diagnosed, and their parents were provided with genetic counselling. CONCLUSIONS: PAH gene analysis is a crucial method for PKU diagnosis and prenatal genetic prognosis, even though many uncommon mutations would affect the analysis and diagnosis of genetic abnormalities. PMID- 29176023 TI - The role of enterovirus infections in type 1 diabetes in Tunisia. AB - BACKGROUND: Enteroviral infections have long been suspected in having a role in beta cell destruction and therefore leading to the onset of clinical type 1 diabetes (T1D). The frequency of enterovirus (EV)-related T1D in North Africa is still unknown. The aim of the present study was to investigate the relationship between infection with EV and T1D in Tunisia. METHODS: A total of 95 T1D patients (41 children and 54 adults) and 141 healthy control subjects (57 children and 84 adults) were tested for the presence of EV-RNA by a highly sensitive nested reverse transcription-polymerase chain reaction (RT-PCR) method. RESULTS: EV-RNA was detected more frequently in plasma from diabetic patients than in plasma of controls (31.6% vs. 7.8%, p<0.0001; OR=5.45; 95% CI 2.44-12.43). RT-PCR revealed positive in 53.7% of T1D children and 14.8% of T1D adults. There was a statistically significant difference between children and adults with T1D (p<0.0001). Positivity of EV-RNA according to the time after the occurrence of the disease did not show any significant difference (p=0.34). Anti-glutamic acid decarboxylase (GAD) antibodies were not associated with EV-RNA (p=0.65). CONCLUSIONS: EV-RNA is associated with T1D mellitus in the Tunisian population especially in children. These results support the hypothesis that EV act as environmental risk factors for T1D. PMID- 29176024 TI - How often are clinicians performing genital exams in children with disorders of sex development? AB - BACKGROUND: We sought to determine the frequency with which genital exams (GEs) are performed in children with disorders of sex development (DSD) and ambiguous genitalia (AG) during routine visits to the pediatric endocrine clinic. METHODS: Medical records of children with DSD and AG seen at one large academic center since 2007 were reviewed. Data analyzed included diagnosis, sex of rearing, age, initial or follow up visit, number of individuals present and sex of the pediatric endocrinologist. Repeated measures analysis was performed to evaluate associations between GEs and patient/physician factors. RESULTS: Eighty-two children with DSD and AG who had a total of 632 visits were identified. Sex of rearing was female in 78% and the most common diagnosis was congenital adrenal hyperplasia (CAH) (68%). GEs were performed in 35.6% of visits. GEs were more likely in patients with male sex of rearing (odds ratio [OR] 17.81, p=0.006), during initial vs. follow-up visits (OR 5.99, p=0.012), and when the examining endocrinologist was female (OR 3.71, p=0.014). As patients aged, GEs were less likely (OR 0.76, p<0.0001). CONCLUSIONS: GEs were performed in approximately one third of clinic visits in children with DSD and AG. Male sex of rearing, initial visits and female pediatric endocrinologist were associated with more frequent GEs. PMID- 29176025 TI - A newborn with combined pituitary hormone deficiency developing shock and sludge. AB - A male neonate was born at 41 weeks of gestation with a birth weight of 3320 g. Artificial respiratory management was required due to respiratory disturbance 1 h after birth, and subsequently catecholamine-refractory low cardiac output-induced shock occurred. Severe combined pituitary hormone deficiency (CPHD) was considered based on the presence of his respiratory disturbance, hypoglycemia and micropenis. After hydrocortisone (HDC) administration, circulatory dynamics rapidly improved. Brain magnetic resonance imaging (MRI) showed aplasia of the anterior pituitary gland and ectopic posterior gland. gamma Glutamyltranspeptidase (gamma-GTP) increased from day 10 after birth and direct bilirubin increased from day 18. On ultrasonography, sludge filling the common bile duct and gall bladder was observed. After initiating treatment with both ursodeoxycholic acid and recombinant human growth hormone (rhGH), cholestasis improved and the sludge disappeared at 3 months after birth. In newborns with CPHD, severe central adrenal insufficiency might induce cardiogenic shock after birth. Early diagnosis and intervention are necessary. PMID- 29176026 TI - The use of a radiolucent template to improve bone age X-ray quality (BASIC study). AB - BACKGROUND: Left hand and wrist X-rays are conventionally used to assess skeletal maturity using methods such as Tanner-Whitehouse 3 (TW3). We noted a number were poor quality, caused by difficulty with hand placement. We introduced a simple radiolucent hand template to assist in hand positioning and assessed changes in X ray quality and repeat X-ray rates. METHODS: The position of fingers, thumb and overall clarity of bone age X-rays were prospectively scored. In the absence of a validated tool to assess quality a 1-3 scale (poor, borderline, good) was devised. A radiolucent hand template was introduced for use in the intervention group. Need for repeat X-ray was determined by set criteria. RESULTS: The intervention improved scores. More patients scored 3 (good) for positioning of fingers (89.29% and 85.33%, p=0.38), thumb (98.21% and 89.96%, p=0.06) and overall clarity (76.79% and 70.27%, p=0.41) for the intervention (n=56) and control groups (n=259), respectively. No patient required repeat X-ray from the intervention group, compared with 28 in the control group (p=0.007). CONCLUSIONS: Achieving good quality bone age X-rays is more difficult than previously assumed. The use of a radiolucent hand template has been shown to improve hand position and significantly reduce the need for repeat X-ray. PMID- 29176027 TI - Identification of a novel mutation of NR0B1 in a patient with X-linked adrenal hypoplasia and symptomatic treatment. AB - BACKGROUND: X-linked congenital adrenal hypoplasia (X-linked AHC) is characterized by acute onset of primary adrenal insufficiency in infancy or early childhood and hypogonadotropic hypogonadism (HH) at puberty. Mutations in NR0B1, the gene located on Xp21.3 and encoding an orphan nuclear receptor named DAX1, are responsible for this disease. METHODS: The entire coding region of the NR0B1 gene of a 14-year-old X-linked AHC proband as well as his family members was sequenced. Clinical and endocrine evaluations with symptomatic treatment results were recorded. RESULTS: DNA sequencing revealed a missense mutation (c.383-384 insA) in exon 1, which resulted in a novel frameshift mutation, thereby resulting in a truncated protein (p.Leu129 Pro fs*137). The therapeutic trail with an observation period of 20 weeks showed an effective improvement in symptoms of hypogonadism with human chorionic gonadotropin (HCG) administration, including a rapid improvement of serum testosterone level, descending of testicles as well as enlargement of testicles and growth of penis. CONCLUSIONS: Our study identified a novel frameshift mutation of the NR0B1 gene in a proband with X-linked AHC/HH and further expanded the number of NR0B1 mutations reported in the literature. Moreover, the symptomatic treatment observation provided referential evidence in the treatment of X-linked AHC associated hypogonadism and bilateral inguinal cryptorchidism. PMID- 29176028 TI - Higher phthalate concentrations are associated with precocious puberty in normal weight Thai girls. AB - BACKGROUND: The cause of precocious puberty may be associated with genetics and other conditions such as central nervous system (CNS) insults, or the exposure to endocrine disrupting chemicals (EDCs). Phthalates is known to be one of the EDCs and have estrogenic and antiandrogenic activities, and may be associated with advanced puberty. The objective of the study was to determine the association between urinary phthalate metabolites and advanced puberty. METHODS: A cross sectional study was conducted in patients with precocious puberty (breast onset <8 years, n=42) and early puberty (breast onset 8-9 years, n=17), compared to age matched controls (n=77). Anthropometric measurements, estradiol, basal and gonadotropin releasing hormone (GnRH)-stimulated follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels, uterine sizes, ovarian diameters and bone ages (BA) were obtained. Urine samples were collected and mono-methyl phthalate (MMP) and mono-ethyl phthalate (MEP) were analyzed by high performance liquid chromatography (HPLC) and adjusted with urine creatinine. RESULTS: The median adjusted-MEP concentration in girls with precocious puberty, was greater than in normal girls (6105.09 vs. 4633.98 MUg/g Cr: p<0.05), and had the same trend among early puberty and normal puberty (5141.41 vs. 4633.98 MUg/g Cr: p=0.4), but was not statistically significant. CONCLUSIONS: Precocious puberty girls had an association with increased MEP concentration. This is the first report of the association between urinary phthalate levels and precocious puberty in Thai girls.

PMID- 29176029 TI - Serum progranulin levels in relation to insulin resistance in childhood obesity. AB - BACKGROUND: Progranulin is an adipokine that is involved in the inflammatory response, glucose metabolism, insulin resistance, and may therefore be involved in chronic subclinical inflammation associated with the pathogenesis of childhood obesity. We aimed to investigate the association of circulating progranulin levels with metabolic parameters in children and to assess the importance of progranulin as a biomarker for metabolic diseases. METHODS: A total of 150 children were consecutively recruited from the Pediatric Nutrition Clinics at King Abdulaziz University Hospital in Jeddah, Saudi Arabia. Children were classified into four groups based on quartile for serum progranulin. Anthropometric variables were measured in all study subjects. Fasting blood samples were collected for measurement of blood glucose, insulin and lipid profile. RESULTS: Children within the upper quartile for serum progranulin concentration were heavier, more insulin resistant and had higher concentrations of serum total cholesterol, triglycerides, insulin and high sensitivity C reactive protein compared to those in the lower quartile. On correlation analysis, serum progranulin concentrations were significantly related to general and central adiposity, metabolic parameters, markers of inflammation and insulin resistance. Stepwise multiple regression showed that 26.6% of the variability in serum progranulin could be explained by measures of adiposity. CONCLUSIONS: The increased serum progranulin concentrations were closely related to measures of adiposity, metabolic parameters, inflammatory marker and insulin resistance indices, suggesting that progranulin may be an excellent biomarker for obesity in childhood. PMID- 29176031 TI - The neurophysiology of working memory development: from childhood to adolescence and young adulthood. AB - Working memory (WM) is an important cognitive function that is necessary to perform our daily activities. The present review briefly describes the most accepted models underlying WM and the neural networks involved in its processing. The review focuses on how the neurophysiological mechanisms develop with age in the periods from childhood to adolescence and young adulthood. Studies using behavioral, neuroimaging, and electrophysiological techniques showed the progress of WM throughout the development. The present review focuses on the neurophysiology of the basic processes underlying WM operations, as indicated by electroencephalogram-derived signals, in order to take advantage of the excellent time resolution of this technique. Children and adults use similar cerebral mechanisms and areas to encode, recognize, and keep the stimuli in memory and update the WM contents, although adults rely more on anterior sites. The possibility that a functional reorganization of WM brain processing occurs around the adolescent period is suggested, and would partly justify the high prevalence of the emergence of mental pathology in the adolescent period. PMID- 29176032 TI - Predictive validity of pre-admission assessments on medical student performance. AB - Objectives: To examine the predictive validity of pre-admission variables on students' performance in a medical school in Saudi Arabia. Methods: In this retrospective study, we collected admission and college performance data for 737 students in preclinical and clinical years. Data included high school scores and other standardized test scores, such as those of the National Achievement Test and the General Aptitude Test. Additionally, we included the scores of the Test of English as a Foreign Language (TOEFL) and the International English Language Testing System (IELTS) exams. Those datasets were then compared with college performance indicators, namely the cumulative Grade Point Average (cGPA) and progress test, using multivariate linear regression analysis. Results: In preclinical years, both the National Achievement Test (p=0.04, B=0.08) and TOEFL (p=0.017, B=0.01) scores were positive predictors of cGPA, whereas the General Aptitude Test (p=0.048, B=-0.05) negatively predicted cGPA. Moreover, none of the pre-admission variables were predictive of progress test performance in the same group. On the other hand, none of the pre-admission variables were predictive of cGPA in clinical years. Overall, cGPA strongly predict-ed students' progress test performance (p<0.001 and B=19.02). Conclusions: Only the National Achievement Test and TOEFL significantly predicted performance in preclinical years. However, these variables do not predict progress test performance, meaning that they do not predict the functional knowledge reflected in the progress test. We report various strengths and deficiencies in the current medical college admission criteria, and call for employing more sensitive and valid ones that predict student performance and functional knowledge, especially in the clinical years. PMID- 29176033 TI - TNFalpha-senescence initiates a STAT-dependent positive feedback loop, leading to a sustained interferon signature, DNA damage, and cytokine secretion. AB - Cellular senescence is a cell fate program that entails essentially irreversible proliferative arrest in response to damage signals. Tumor necrosis factor-alpha (TNFalpha), an important pro-inflammatory cytokine secreted by some types of senescent cells, can induce senescence in mouse and human cells. However, downstream signaling pathways linking TNFalpha-related inflammation to senescence are not fully characterized. Using human umbilical vein endothelial cells (HUVECs) as a model, we show that TNFalpha induces permanent growth arrest and increases p21CIP1, p16INK4A, and SA-beta-gal, accompanied by persistent DNA damage and ROS production. By gene expression profiling, we identified the crucial involvement of inflammatory and JAK/STAT pathways in TNFalpha-mediated senescence. We found that TNFalpha activates a STAT-dependent autocrine loop that sustains cytokine secretion and an interferon signature to lock cells into senescence. Furthermore, we show STAT1/3 activation is necessary for cytokine and ROS production during TNFalpha-induced senescence. However, inhibition of STAT1/3 did not rescue cells from proliferative arrest, but rather suppressed cell cycle regulatory genes and altered TNFalpha-induced senescence. Our findings suggest a positive feedback mechanism via the STAT pathway that sustains cytokine production and reveal a reciprocal regulatory role of JAK/STAT in TNFalpha mediated senescence. PMID- 29176034 TI - Selenium preserves keratinocyte stemness and delays senescence by maintaining epidermal adhesion. AB - Skin is constantly exposed to environmental factors such as pollutants, chemicals and ultra violet radiation (UV), which can induce premature skin aging and increase the risk of skin cancer. One strategy to reduce the effect of oxidative stress produced by environmental exposure is the application of antioxidant molecules. Among the endogenous antioxidants, selenoproteins play a key role in antioxidant defense and in maintaining a reduced cellular environment. Selenium, essential for the activity of selenoproteins, is a trace element that is not synthesized by organisms and must be supplied by diet or supplementation. The aim of this study is to evaluate the effect of Selenium supplementation on skin aging, especially on keratinocytes, the main cells of the epidermis. Our results demonstrate for the first time to our knowledge, the major role of Selenium on the replicative life span of keratinocytes and on aging skin. Selenium protects keratinocyte stem cells (KSCs) against senescence via preservation of their stemness phenotype through adhesion to the basement membrane. Additionally, Selenium supplementation maintains the homeostasis of skin during chronological aging in our senescent skin equivalent model. Controlled supplementation with Selenium could be a new strategy to protect skin against aging. PMID- 29176036 TI - One-step delivery of a functional multi-layered cell sheet using a thermally expandable hydrogel with controlled presentation of cell adhesive proteins. AB - In this study, we developed a new system enabling rapid delivery of a multi layered cell sheet by combining layer-by-layer (LBL) coating of a cell membrane and surface engineered thermally expandable hydrogel. Human dermal fibroblasts were LBL-coated with fibronectin (FN) and gelatin to form a multi-layered cell sheet in a single seeding step via spontaneous 3D cell-cell interactions. FN was covalently immobilized onto the surface of a Tetronic(r)-based hydrogel at two different concentrations (1 and 5 MUg ml-1) for stable adhesion of the multi layered cell sheet, followed by polydopamine coating. In both conditions, a multi layered cell sheet was stably formed. Then, the cell sheet on the hydrogel modified with 1 MUg ml-1 FN rapidly detached (>90% efficiency) in response to the expansion of the hydrogel when temperature changed from 37 degrees C to 4 degrees C, while the other group had a reduced detachment due to excessive cell hydrogel interaction. The multi-layered cell sheet was evident in cell extracellular matrix and cell-cell junction formation, and bFGF was continuously secreted over 7 days of in vitro culture. The multi-layered transplanted to the mouse subcutaneous tissue also exhibited evidence of vascular ingrowth, which collectively suggest that the delivery system maintaining cellular functions is applicable for regenerative medicine. PMID- 29176035 TI - Coaxial extrusion bioprinting of 3D microfibrous constructs with cell-favorable gelatin methacryloyl microenvironments. AB - Bioinks with shear-thinning/rapid solidification properties and strong mechanics are usually needed for the bioprinting of three-dimensional (3D) cell-laden constructs. As such, it remains challenging to generate soft constructs from bioinks at low concentrations that are favorable for cellular activities. Herein, we report a strategy to fabricate cell-laden constructs with tunable 3D microenvironments achieved by bioprinting of gelatin methacryloyl (GelMA)/alginate core/sheath microfibers, where the alginate sheath serves as a template to support and confine the GelMA pre-hydrogel in the core during the extrusion process, allowing for subsequent UV crosslinking. This novel strategy minimizes the bioprinting requirements for the core bioink, and facilitates the fabrication of cell-laden GelMA constructs at low concentrations. We first showed the capability of generating various alginate hollow microfibrous constructs using a coaxial nozzle setup, and verified the diffusibility and perfusability of the bioprinted hollow structures that are important for the tissue engineering applications. More importantly, the hollow alginate microfibers were then used as templates for generating cell-laden GelMA constructs with soft microenvironments, by using GelMA pre-hydrogel as the bioink for the core phase during bioprinting. As such, GelMA constructs at extremely low concentrations (<2.0%) could be extruded to effectively support cellular activities including proliferation and spreading for various cell types. We believe that our strategy is likely to provide broad opportunities in bioprinting of 3D constructs with cell-favorable microenvironments for applications in tissue engineering and pharmaceutical screening. PMID- 29176037 TI - Quantitative analysis of charge trapping and classification of sub-gap states in MoS2 TFT by pulse I-V method. AB - The threshold voltage instabilities and huge hysteresis of MoS2 thin film transistors (TFTs) have raised concerns about their practical applicability in next-generation switching devices. These behaviors are associated with charge trapping, which stems from tunneling to the adjacent trap site, interfacial redox reaction and interface and/or bulk trap states. In this report, we present quantitative analysis on the electron charge trapping mechanism of MoS2 TFT by fast pulse I-V method and the space charge limited current (SCLC) measurement. By adopting the fast pulse I-V method, we were able to obtain effective mobility. In addition, the origin of the trap states was identified by disassembling the sub gap states into interface trap and bulk trap states by simple extraction analysis. These measurement methods and analyses enable not only quantitative extraction of various traps but also an understanding of the charge transport mechanism in MoS2 TFTs. The fast I-V data and SCLC data obtained under various measurement temperatures and ambient show that electron transport to neighboring trap sites by tunneling is the main charge trapping mechanism in thin-MoS2 TFTs. This implies that interfacial traps account for most of the total sub-gap states while the bulk trap contribution is negligible, at approximately 0.40% and 0.26% in air and vacuum ambient, respectively. Thus, control of the interface trap states is crucial to further improve the performance of devices with thin channels. PMID- 29176038 TI - The effect of age on balancing behavior: complexity analysis of mediolateral force trajectories. AB - OBJECTIVE: We quantified, via complexity analysis, the postural stability of healthy people from a wide age range. APPROACH: Thirty-five healthy people aged 18-72 performed three tasks while balancing on one foot on a force plate: standard balancing task, mental task (balancing while answering basic arithmetic questions), and knot-tying task (balancing while tying two knots in a piece of ribbon). Mediolateral force trajectories were analyzed to determine control strategy via Hurst exponents, Lyapunov exponents, Kolmogorov complexity, root mean square, and phase-space plots. MAIN RESULTS: We found increased pattern repetition in balancing with increased age, as evidenced by the emergence of a double attractor pattern in phase-space plots and the increase of Hurst exponents with age from approximately 0.3 to 0.8. SIGNIFICANCE: As people age, they tend to develop strong feed-forward control strategies for balancing, and lose the complexity of micro movements intrinsic to young age. There is an open-loop control strategy for balancing that emerges in older adulthood, and there are attractors inherent to balancing which begin to develop in middle age. PMID- 29176039 TI - Diffusion tensor optical coherence tomography. AB - In situ measurements of diffusive particle transport provide insight into tissue architecture, drug delivery, and cellular function. Analogous to diffusion-tensor magnetic resonance imaging (DT-MRI), where the anisotropic diffusion of water molecules is mapped on the millimeter scale to elucidate the fibrous structure of tissue, here we propose diffusion-tensor optical coherence tomography (DT-OCT) for measuring directional diffusivity and flow of optically scattering particles within tissue. Because DT-OCT is sensitive to the sub-resolution motion of Brownian particles as they are constrained by tissue macromolecules, it has the potential to quantify nanoporous anisotropic tissue structure at micrometer resolution as relevant to extracellular matrices, neurons, and capillaries. Here we derive the principles of DT-OCT, relating the detected optical signal from a minimum of six probe beams with the six unique diffusion tensor and three flow vector components. The optimal geometry of the probe beams is determined given a finite numerical aperture, and a high-speed hardware implementation is proposed. Finally, Monte Carlo simulations are employed to assess the ability of the proposed DT-OCT system to quantify anisotropic diffusion of nanoparticles in a collagen matrix, an extracellular constituent that is known to become highly aligned during tumor development. PMID- 29176041 TI - Positioning of head and neck patients for proton therapy using proton range probes: a proof of concept study. AB - To exploit the full potential of proton therapy, accurate and on-line methods to verify the patient positioning and the proton range during the treatment are desirable. Here we propose and validate an innovative technique for determining patient misalignment uncertainties through the use of a small number of low dose, carefully selected proton pencil beams ('range probes') (RP) with sufficient energy that their residual Bragg peak (BP) position and shape can be measured on exit. Since any change of the patient orientation in relation to these beams will result in changes of the density heterogeneities through which they pass, our hypothesis is that patient misalignments can be deduced from measured changes in Bragg curve (BC) shape and range. As such, a simple and robust methodology has been developed that estimates average proton range and range dilution of the detected residual BC, in order to locate range probe positions with optimal prediction power for detecting misalignments. The validation of this RP based approach has been split into two phases. First we retrospectively investigate its potential to detect translational patient misalignments under real clinical conditions. Second, we test it for determining rotational errors of an anthropomorphic phantom that was systematically rotated using an in-house developed high precision motion stage. Simulations of RPs in these two scenarios show that this approach could potentially predict translational errors to lower than1.5 mm and rotational errors to smaller than 1 degrees using only three or five RPs positions respectively. PMID- 29176040 TI - Characteristic impedance: frequency or time domain approach? AB - OBJECTIVE: Characteristic impedance (Zc) is an important component in the theory of hemodynamics. It is a commonly used metric of proximal arterial stiffness and pulse wave velocity. Calculated using simultaneously measured dynamic pressure and flow data, estimates of characteristic impedance can be obtained using methods based on frequency or time domain analysis. Applications of these methods under different physiological and pathological conditions in species with different body sizes and heart rates show that the two approaches do not always agree. In this study, we have investigated the discrepancies between frequency and time domain estimates accounting for uncertainties associated with experimental processes and physiological conditions. APPROACH: We have used published data measured in different species including humans, dogs, and mice to investigate: (a) the effects of time delay and signal noise in the pressure-flow data, (b) uncertainties about the blood flow conditions, (c) periodicity of the cardiac cycle versus the breathing cycle, on the frequency and time domain estimates of Zc, and (d) if discrepancies observed under different hemodynamic conditions can be eliminated. Main results and Significance: We have shown that the frequency and time domain estimates are not equally sensitive to certain characteristics of hemodynamic signals including phase lag between pressure and flow, signal to noise ratio and the end of systole retrograde flow. The discrepancies between two types of estimates are inherent due to their intrinsically different mathematical expressions and therefore it is impossible to define a criterion to resolve such discrepancies. Considering the interpretation and role of Zc as an important hemodynamic parameter, we suggest that the frequency and time domain estimates should be further assessed as two different hemodynamic parameters in a future study. PMID- 29176042 TI - Perfect transmission of 3D massive Kane fermions in HgCdTe Veselago lenses. AB - The transmission properties of three-dimensional (3D) massive Kane fermions in HgCdTe (MCT) heterojunctions have been studied using the simplified Kane-Mele model. Based on our theoretical calculations, we propose the design of an electronic device, called a mass inverter, which consists of the junction of a narrow-gap semiconductor and semimetal. Such a device can be used in electron optics applications, since it operates as a Veselago lens and presents Klein tunneling (KT) of 3D massive Kane fermions under normal incidence. We found that KT and Veselago lensing can also be observed for general MCT heterojunctions with a specific value of doping level. We show that non-resonant perfect transmission of massive Kane fermions persists in a potential barrier for heterojunctions formed by a semimetal between two standard semiconductors. This effect is quite robust when the ideal conditions of a possible experimental test are deviated. Our findings may have important implications in the development of nano electronic devices using 3D massive Kane fermions, where transmission features of massless particles are recovered. PMID- 29176043 TI - Sympodial tree-like structures: from small to large-amplitude vibrations. AB - This study deals with tree-like structures that mimic a trunk with either first order branches or both first and second-order branches of a sympodial tree. The corresponding mechanical model comprises physical pendula coupled with torsional springs and viscous dampers. Natural frequencies and modal shapes are obtained analytically and the effects of a branching angle and a stiffness ratio on their change is analysed. Then, the trunk is harmonically excited and the corresponding structural response is investigated, both for small undamped and damped vibrations, focusing on the concept of dynamic absorbers and the attenuation of the amplitude of the trunk and first-order branches as this attenuation is beneficial for practical engineering applications. The corresponding frequencies at which these amplitudes are equal to zero or in resonance are determined. Finally, free large-amplitude vibrations are examined. Conditions for internal resonances in the structure with first-order branching are determined analytically by using the method of multiple scales. Frequency spectra of large amplitude vibrations are obtained numerically focusing on the influence of the branching angle on their content. Biomimetic potentials and advantages of designing these coupled branched structures are discussed through the whole study via the influence of the stiffness ratio of the springs, the branching angle and the hierarchy of branches on their response.

AB - In an attempt to bridge the pressure gap, APXPS was used to follow the surface development of an aluminum brazing sheet during heating in an ambient oxygen pressure mimicking the environment of an industrial brazing furnace. The studied aluminum alloy brazing sheet is a composite material consisting of two aluminum alloy standards whose surface is covered with a native aluminum oxide film. To emphasize the necessity of studies of this system in ambient sample environments it is compared to measurements in UHV. Changes in thickness and composition of the surface oxide were followed after heating to 300 degrees C, 400 degrees C, and 500 degrees C. The two sets presented in this paper show that the surface development strongly depends on the environment the sample is heated in. PMID- 29176045 TI - Thermal annealing and pressure effects on BaFe2 xCoxAs2 single crystals. AB - We investigate the pressure and thermal annealing effects on BaFe2 xCoxAs2 (Co-Ba122) single crystals with x = 0.1 and 0.17 via electrical transport measurements. The thermal annealing treatment not only enhances the superconducting transition temperature (Tc) from 9.6 to 12.7 K for x = 0.1 and from 18.1 to 21.0 K for x = 0.17, but also increases the antiferromagnetic transition temperature (TN). Simultaneous enhancement of Tc and TN by the thermal annealing treatment indicates that thermal annealing could substantially improve the quality of the Co-doped Ba122 samples. Interestingly, Tc of the Co-Ba122 compounds shows a scaling behavior with a linear dependence on the resistivity value at 290 K, irrespective of tuning parameters, such as chemical doping, pressure, and thermal annealing. These results not only provide an effective way to access the intrinsic properties of the BaFe2As2 system, but also may shed a light on designing new materials with higher superconducting transition temperature. PMID- 29176046 TI - Lanthanide stannate pyrochlores (Ln2Sn2O7; Ln = Nd, Gd, Er) at high pressure. AB - Lanthanide stannate pyrochlores (Ln2Sn2O7; Ln = Nd, Gd, and Er) were investigated in situ to 50 GPa in order to determine their structural response to compression and compare their response to that of lanthanide titanate, zirconate, and hafnate pyrochlores. The cation radius ratio of A3+/B4+ in pyrochlore oxides (A2B2O7) is thought to be the dominant feature that influences their response on compression. The ionic radius of Sn4+ is intermediate to that of Ti4+, Zr4+, and Hf4+, but the bond in stannate pyrochlore is more covalent than the bonds in titanates, zirconate, and hafnates. In stannates, based on in situ Raman spectroscopy, pyrochlore cation and anion sublattices begin to disorder with the onset of compression, first measured at 0.3 GPa. The extent of sublattice disorder versus pressure is greater in stannates with a smaller Ln3+ cation. Stannate pyrochlores (Fd-3m) begin a sluggish transformation to an orthorhombic, cotunnite-like structure at ~28 GPa; similar transitions have been observed in titanate, zirconate, and hafnate pyrochlores at varying pressures (18-40 GPa) with cation radius ratio. The extent of the phase transition versus pressure varies directly with the size of the Ln3+ cation. Post-decompression from ~50 GPa, Er2Sn2O7 and Gd2Sn2O7 adopt a pyrochlore structure, rather than the multi scale defect-fluorite + weberite-type structure adopted by Nd2Sn2O7 that is characteristic of titanate, zirconate, and hafnate pyrochlores under similar conditions. Like pyrochlore titanates, zirconates, and hafnates, the bulk modulus, B 0, of stannates varies linearly and inversely with cation radius ratio from 1 1 1 GPa (Nd2Sn2O7) to 251 GPa (Er2Sn2O7). The trends of bulk moduli in stannates in this study are in excellent agreement with previous experimental studies on stannates and suggest that the size of the Ln3+ cation is the primary determining factor of B 0. Additionally, when normalized to r A/r B, the bulk moduli of stannates are comparable to those of zirconates and hafnates, which vary from titanates. Our results suggest that the cation radius ratio strongly influences the bulk moduli of stannates, as well as their overall compression response.

AB - Here, we present a silver atomic-scale device fabricated and operated by a combined technique of electrochemical control (EC) and mechanically controllable break junction (MCBJ). With this EC-MCBJ technique, we can perform mechanically controllable bistable quantum conductance switching of a silver quantum point contact (QPC) in an electrochemical environment at room temperature. Furthermore, the silver QPC of the device can be controlled both mechanically and electrochemically, and the operating mode can be changed from 'electrochemical' to 'mechanical', which expands the operating mode for controlling QPCs. These experimental results offer the perspective that a silver QPC may be used as a contact for a nanoelectromechanical relay. PMID- 29176048 TI - Enhanced photocatalytic water-splitting performance using Fe-doped hierarchical TiO2 ball-flowers. AB - The photocatalytic water-splitting behavior of hierarchically structured TiO2 ball-flowers with different Fe ion contents was studied, in order to elucidate the effects of Fe doping on their water-splitting performance. It was found that with the increase of Fe doping content, the hydrogen evolution rate increased initially and then decreased. The highest hydrogen evolution of 697 MUmol g-1 is observed for 2Fe/TiO2, after 4 h of light irradiation, which was five times greater than that in the case of pure TiO2 who has 140 MUmol g-1 hydrogen evolution after 4 h of light irradiation. This improvement in the water-splitting efficiency owing to optimized Fe doping could be attributed to an enhancement in the visible-light absorption characteristics and an increase in the number of oxygen vacancies, which act as the reaction sites for water splitting. PMID- 29176049 TI - Flexible robust binder-free carbon nanotube membranes for solid state and microcapacitor application. AB - We present a liquid phase post synthesis self-assemble protocol that transforms trillions of carbon nanotubes (CNTs) in powder form into densely packed flexible, robust and binder-free macroscopic membranes with a hierarchical pore structure. We employ charge transfer engineering to spontaneously disperse the CNTs in a liquid medium. The processing protocol has limited or no impact on the intrinsic properties of the CNTs. As the thickness of the CNT membrane is increased, we observed a gradual transition from high flexibility to buckling and brittleness in the flexural properties of the membranes. The binder-free CNT membranes have bulk mass density greater than that of water (1.0 g cm-3). We correlate the mass of the CNTs in the membrane to the thickness of the membrane and obtained a bulk mass density of ~1.11 g cm-3 +/- 0.03 g cm-3. We demonstrate the use of the CNT membranes as electrode in a pristine and oxidized single/stacked solid-state capacitor as well as pristine interdigitated microcapacitor that show time constant of ~32 ms with no degradation in performance even after 10 000 cycles. The capacitors show very good temperature dependence over a wide range of temperatures with good cycling performance up to 90 degrees C. The specific capacitance of the pseudocapacitive CNT electrode at room temperature was 72 F g 1 and increased to 100 F g-1 at 70 degrees C. The leakage current of bipolar stacked solid state capacitor was ~100 nA cm-2 at 2.5 V when held for 72 h. PMID- 29176050 TI - Visible light-induced electronic structure modulation of Nb- and Ta-doped alpha Fe2O3 nanorods for effective photoelectrochemical water splitting. AB - The photoelectrochemical (PEC) water splitting activity of Nb and Ta-doped hematite (alpha-Fe2O3) nanorods was investigated with reference to electronic structures by in situ synchrotron x-ray absorption spectroscopy (XAS). Current density-potential measurements demonstrate that the PEC activity of alpha-Fe2O3 nanorods depends strongly on the species and concentrations of dopants. The doping of alpha-Fe2O3 nanorods with a low level of Nb or Ta can improve their electrical conductivity and thereby facilitate charge transport and reduced electron-hole recombination therein. The photoconversion effects of Nb and Ta doped alpha-Fe2O3 by in situ XAS in the dark and under illumination revealed opposite evolutions of the spectral intensities of the Fe L-edge and Nb/Ta L edge, indicating that charge transfer and a conduction pathway are involved in the photoconversion. Analytic in situ XAS results reveal that the alpha-Fe2O3 that is doped with a low level of Nb has a greater photoconversion efficiency than that doped with Ta because Nb sites are more active than Ta sites in alpha Fe2O3. The correlation between PEC activity and the electronic structure of Nb/Ta doped alpha-Fe2O3 is examined in detail using in situ XAS and helps to elucidate the mechanism of PEC water splitting in terms of the electronic structure. PMID- 29176051 TI - Polymer-based doping control for performance enhancement of wet-processed short channel CNTFETs. AB - The electrical transport properties of short-channel transistors based on single walled carbon nanotubes (CNT) are significantly affected by bundling along with solution processing. We report that especially high off currents of CNT transistors are not only related to the incorporation of metallic CNTs but also to the incorporation of CNT bundles. By applying device passivation with poly(4 vinylpyridine), the impact of CNT bundling on the device performance can be strongly reduced due to increased gate efficiency as well as reduced oxygen and water-induced p-type doping, boosting essential field-effect transistor performance parameters by several orders of magnitude. Moreover, this passivation approach allows the hysteresis and threshold voltage of CNT transistors to be tuned. PMID- 29176053 TI - Retardation effects on the dispersion and propagation of plasmons in metallic nanoparticle chains. AB - We consider a chain of regularly-spaced spherical metallic nanoparticles, where each particle supports three degenerate localized surface plasmons. Due to the dipolar interaction between the nanoparticles, the localized plasmons couple to form extended collective modes. Using an open quantum system approach in which the collective plasmons are interacting with vacuum electromagnetic modes and which, importantly, readily incorporates retardation via the light-matter coupling, we analytically evaluate the resulting radiative frequency shifts of the plasmonic bandstructure. For subwavelength-sized nanoparticles, our analytical treatment provides an excellent quantitative agreement with the results stemming from laborious numerical calculations based on fully-retarded solutions to Maxwell's equations. Indeed, the explicit expressions for the plasmonic spectrum which we provide showcase how including retardation gives rise to a logarithmic singularity in the bandstructure of transverse-polarized plasmons. We further study the impact of retardation effects on the propagation of plasmonic excitations along the chain. While for the longitudinal modes, retardation has a negligible effect, we find that the retarded dipolar interaction can significantly modify the plasmon propagation in the case of transverse-polarized modes. Moreover, our results elucidate the analogy between radiative effects in nanoplasmonic systems and the cooperative Lamb shift in atomic physics. PMID- 29176052 TI - Development of a dual-ended readout detector with segmented crystal bars made using a subsurface laser engraving technique. AB - Depth of interaction (DOI) information is indispensable to improving the sensitivity and spatial resolution of positron emission tomography (PET) systems, especially for small field-of-view PET such as small animal PET and human brain PET. We have already developed a series of X'tal cube detectors for isotropic spatial resolution and we obtained the best isotropic resolution of 0.77 mm for detectors with six-sided readout. However, it is still challenging to apply the detector for PET systems due to the high cost of six-sided readout electronics and carrying out segmentation of a monolithic cubic scintillator in three dimensions using the subsurface laser engraving (SSLE) technique. In this work, we propose a more practical X'tal cube with a two-sided readout detector, which is made of crystal bars segmented in the height direction only by using the SSLE technique. We developed two types of prototype detectors with a 3 mm cubic segment and a 1.5 mm cubic segment by using 3 * 3 * 20 mm3 and 1.5 * 1.5 * 20 mm3 crystal bars segmented into 7 and 13 DOI segments, respectively, using the SSLE technique. First, the performance of the detector, composed of one crystal bar with different DOI segments and two thorough silicon via (TSV) multi pixel photon counters (MPPCs) as readout at both ends of the crystal bar, were evaluated in order to demonstrate the capability of the segmented crystal bars as a DOI detector. Then, performance evaluation was carried out for a 4 * 4 crystal array of 3 * 3 * 20 mm3 with 7 DOI segments and an 8 * 8 crystal array of 1.5 * 1.5 * 20 mm3 with 13 DOI segments. Each readout included a 4 * 4 channel of the 3 * 3 mm2 active area of the TSV MPPCs. The three dimensional position maps of the detectors were obtained by the Anger-type calculation. All the segments in the 4 * 4 array were identified very clearly when there was air between the crystal bars, as each crystal bar was coupled to one channel of the MPPCs; however, it was necessary to optimize optical conditions between crystal bars for the 8 * 8 array because of light sharing between crystal bars coupled to one channel of the MPPCs. The optimization was performed for the 8 * 8 array by inserting reflectors fully or partially between the crystal bars and the best crystal identification performance was obtained with the partial reflectors between the crystal bars. The mean energy resolutions at the 511 keV photo peak for the 4 * 4 array with air between the crystal bars and for the 8 * 8 array with partial reflectors between the crystal bars were 10.1% +/- 0.3% and 10.8% +/- 0.8%, respectively. Timing resolutions of 783 +/- 36 ps and 1.14 +/- 0.22 ns were obtained for the detectors composed of the 4 * 4 array and the 8 * 8 array with partial reflectors, respectively. These values correspond to single photon timing resolutions. Practical X'tal cubes with 3 mm and 1.5 mm DOI resolutions and two sided readout were developed. PMID- 29176054 TI - Synthesis of thiolated arabinoxylan and its application as sustained release mucoadhesive film former. AB - The present work aimed to synthesize thiolated arabinoxylan (TAX), and to evaluate its mucoadhesive potential. Synthesis of TAX was accomplished by esterification of arabinoxylan (AX) with thioglycolic acid (TGA). The appearance of a characteristic peak at 2516 cm-1 in the FTIR spectrum of TAX, and presence of 6.01 +/- 1.03 m moles of thiol per gram of the polymer confirmed successful thiolation of AX. The incorporation of the thiol group considerably promoted mucoadhesive strength of the polymer-viz. 3.99-fold. Moreover, in vivo safety analysis in albino rats revealed TAX to be safe in the concentration range of 750 1000 mg kg-1 body weight. Synthesized TAX was utilized to prepare Tizanidine HCl (TZN HCl) loaded sustained release (SR) mucoadhesive buccal films using a solvent casting technique. Results proved that the prepared films were of uniform thickness, good mechanical strength (with folding endurance >300), acceptable moisture contents (5%-7%) and surface pH (6.23 +/- 0.81 to 6.43 +/- 0.49) compatible to that of the buccal cavity. Presence of greater that 90% of drug contents indicated the excellent drug loading ability of the prepared films. Results of in vitro dissolution studies and ex vivo permeation studies conducted respectively by USP dissolution apparatus II and Franz diffusion cell indicated that sustained effect of TAX was achieved for 8 h. These results have conclusively proven that TAX has the potential to improve the bioavailability of TZN HCl due to enhanced mucoadhesion in buccal cavity, hence signifying its suitability as a mucoadhesive buccal film former. PMID- 29176055 TI - Multiscale assembly of solution-processed organic electronics: the critical roles of confinement, fluid flow, and interfaces. AB - Organic semiconducting small molecules and polymers provide a rich phase space for investigating the fundamentals of molecular and hierarchical assembly. Stemming from weak intermolecular interactions, their assembly sensitively depends on processing conditions, which in turn drastically modulate their electronic properties. Much work has gone into molecular design strategies that maximize intermolecular interactions and encourage close packing. Less understood, however, is the non-equilibrium assembly that occurs during the fabrication process (especially solution coating and printing) which is critical to determining thin film morphology across length scales. This encompasses polymorphism and molecular packing at molecular scale, assembly of pi-bonding aggregates at the tens of nanometers scale, and the formation of domains at the micron-millimeter device scale. Here, we discuss three phenomena ubiquitous in solution processing of organic electronic thin films: the confinement effect, fluid flows, and interfacial assembly and the role they play in directing assembly. This review focuses on the mechanistic understanding of how assembly outcomes couple closely to the solution processing environment, supported by salient examples from the recent literature. PMID- 29176056 TI - Calculation of the exposure buildup factors for X-ray photons with continuous energy spectrum by Monte Carlo code. AB - The exposure buildup factors are very important for the calculation of radiation shielding and also applied radiation. We must distinguish the monoenergetic and continuous energy spectrum gamma source in order to calculate the exposure buildup factors. In this study, the exposure buildup factors for two X-ray continuous energy spectrum (bremsstrahlung) with 5 and 10 MeV endpoint energy were calculated up to depths 10 mfp of water. It was observed that there is a large difference between the obtained exposure buildup factors due to the monoenergetic and continuous energy spectrum gamma source. The calculation results show that the relative differences in 5 MeV energy for 1 mfp to 10 mfp are 114% to 44%, respectively, and also the relative differences in 10 MeV energy for 1 mfp to 10 mfp are 87% to 38%, respectively. Actually, the main purpose of this paper is to illustrate the fact that there is a significant difference between the exposure buildup factor due to the continuous and monoenergetic gamma source. Therefore, radiation staffs must pay more attention to calculate the thickness of the radiation shields for continuous energy gamma source. PMID- 29176058 TI - Self-organized nanocrack networks: a pathway to enlarge catalytic surface area in sputtered ceramic thin films, showcased for photocatalytic TiO2. AB - Sputter deposited photocatalytic thin films offer high adherence and mechanical stability, but typically are outperformed in their photocatalytic properties by colloidal TiO2 nanostructures, which in turn typically suffer from problematic removal. Here we report on thermally controlled nanocrack formation as a feasible and batch applicable approach to enhance the photocatalytic performance of well adhering, reactively sputtered TiO2 thin films. Networks of nanoscopic cracks were induced into tailored columnar TiO2 thin films by thermal annealing. These deep trenches are separating small bundles of TiO2 columns, adding their flanks to the overall catalytically active surface area. The variation of thin film thickness reveals a critical layer thickness for initial nanocrack network formation, which was found to be about 400 nm in case of TiO2. The columnar morphology of the as deposited TiO2 layer with weak bonds between respective columns and with strong bonds to the substrate is of crucial importance for the formation of nanocrack networks. A beneficial effect of nanocracking on the photocatalytic performance was experimentally observed. It was correlated by a simple geometric model for explaining the positive impact of the crack induced enlargement of active surface area on photocatalytic efficiency. The presented method of nanocrack network formation is principally not limited to TiO2 and is therefore seen as a promising candidate for utilizing increased surface area by controlled crack formation in ceramic thin films in general. PMID- 29176057 TI - Acoustic-based proton range verification in heterogeneous tissue: simulation studies. AB - Acoustic-based proton range verification (protoacoustics) is a potential in vivo technique for determining the Bragg peak position. Previous measurements and simulations have been restricted to homogeneous water tanks. Here, a CT-based simulation method is proposed and applied to a liver and prostate case to model the effects of tissue heterogeneity on the protoacoustic amplitude and time-of flight range verification accuracy. For the liver case, posterior irradiation with a single proton pencil beam was simulated for detectors placed on the skin. In the prostate case, a transrectal probe measured the protoacoustic pressure generated by irradiation with five separate anterior proton beams. After calculating the proton beam dose deposition, each CT voxel's material properties were mapped based on Hounsfield Unit values, and thermoacoustically-generated acoustic wave propagation was simulated with the k-Wave MATLAB toolbox. By comparing the simulation results for the original liver CT to homogenized variants, the effects of heterogeneity were assessed. For the liver case, 1.4 cGy of dose at the Bragg peak generated 50 mPa of pressure (13 cm distal), a 2* lower amplitude than simulated in a homogeneous water tank. Protoacoustic triangulation of the Bragg peak based on multiple detector measurements resulted in 0.4 mm accuracy for a delta-function proton pulse irradiation of the liver. For the prostate case, higher amplitudes are simulated (92-1004 mPa) for closer detectors (<8 cm). For four of the prostate beams, the protoacoustic range triangulation was accurate to ?1.6 mm (delta-function proton pulse). Based on the results, application of protoacoustic range verification to heterogeneous tissue will result in decreased signal amplitudes relative to homogeneous water tank measurements, but accurate range verification is still expected to be possible. PMID- 29176059 TI - Multi-GPU configuration of 4D intensity modulated radiation therapy inverse planning using global optimization. AB - We report on the design, implementation and characterization of a multi-graphic processing unit (GPU) computational platform for higher-order optimization in radiotherapy treatment planning. In collaboration with a commercial vendor (Varian Medical Systems, Palo Alto, CA), a research prototype GPU-enabled Eclipse (V13.6) workstation was configured. The hardware consisted of dual 8-core Xeon processors, 256 GB RAM and four NVIDIA Tesla K80 general purpose GPUs. We demonstrate the utility of this platform for large radiotherapy optimization problems through the development and characterization of a parallelized particle swarm optimization (PSO) four dimensional (4D) intensity modulated radiation therapy (IMRT) technique. The PSO engine was coupled to the Eclipse treatment planning system via a vendor-provided scripting interface. Specific challenges addressed in this implementation were (i) data management and (ii) non-uniform memory access (NUMA). For the former, we alternated between parameters over which the computation process was parallelized. For the latter, we reduced the amount of data required to be transferred over the NUMA bridge. The datasets examined in this study were approximately 300 GB in size, including 4D computed tomography images, anatomical structure contours and dose deposition matrices. For evaluation, we created a 4D-IMRT treatment plan for one lung cancer patient and analyzed computation speed while varying several parameters (number of respiratory phases, GPUs, PSO particles, and data matrix sizes). The optimized 4D IMRT plan enhanced sparing of organs at risk by an average reduction of [Formula: see text] in maximum dose, compared to the clinical optimized IMRT plan, where the internal target volume was used. We validated our computation time analyses in two additional cases. The computation speed in our implementation did not monotonically increase with the number of GPUs. The optimal number of GPUs (five, in our study) is directly related to the hardware specifications. The optimization process took 35 min using 50 PSO particles, 25 iterations and 5 GPUs. PMID- 29176060 TI - Random dopant fluctuations and statistical variability in n-channel junctionless FETs. AB - The influence of random dopant fluctuations on the statistical variability of the electrical characteristics of n-channel silicon junctionless nanowire transistor (JNT) has been studied using three dimensional quantum simulations based on the non-equilibrium Green's function (NEGF) formalism. Average randomly distributed body doping densities of 2 * 1019, 6 * 1019 and 1 * 1020 cm-3 have been considered employing an atomistic model for JNTs with gate lengths of 5, 10 and 15 nm. We demonstrate that by properly adjusting the doping density in the JNT, a near ideal statistical variability and electrical performance can be achieved, which can pave the way for the continuation of scaling in silicon CMOS technology. PMID- 29176061 TI - Exhaled breath temperature in optimally treated asthmatics: severity and underlying mechanisms. AB - INTRODUCTION: Increased vascularity may lead to loss of heat in the airways and may modulate exhaled breath temperature (EBT). Increased EBT has been associated with uncontrolled asthma. AIM: We wanted to determine whether the measurement of EBT in optimally treated asthmatic patients is influenced by the increased vascular permeability and whether Vascular endothelial growth factor (VEGF) is implicated in the above process. Furthermore, to assess the impact of asthma severity on EBT values. The diagnostic performance of EBT for the identification of inflammatory profiles in induced sputum was also assessed. METHODS: 88 stable asthmatic patients optimally treated for at least 6 months were studied (46 with Severe Refractory Asthma, SRA). EBT was measured with the X-halo device. All patients underwent spirometry, sputum induction for the measurement of % inflammatory cells and for the assessment of both VEGF and albumin in sputum supernatant. The airway vascular permeability index was calculated as the ratio of albumin concentrations in induced sputum and serum. RESULTS: EBT ( degrees C) was significantly higher in patients with SRA compared to those with mild to moderate asthma (median IQR 34.2 [32.4-34.6] versus 31.8 [26.3-34.1], p = 0.001). EBT was significantly associated with VEGF levels in sputum supernatant, while SRA was recognized as a significant co-variate. No other significant associations were observed. Finally, in ROC analysis, the diagnostic performance of EBT for the pure eosinophilic or/and neutrophilic profile did not reach statistical significance. CONCLUSION: EBT is increasing in severe asthma and is significantly modulated by VEGF levels. Despite the above results its performance for predicting cellular profiles is of limited value. PMID- 29176062 TI - Sol-gel TiO2 colloidal suspensions and nanostructured thin films: structural and biological assessments. AB - The role of substrate topography in phenotype expression of in vitro cultured cells has been widely assessed. However, the production of the nanostructured interface via the deposition of sol-gel synthesized nanoparticles (NPs) has not yet been fully exploited. This is also evidenced by the limited number of studies correlating the morphological, structural and chemical properties of the grown thin films with those of the sol-gel 'brick' within the framework of the bottom up approach. Our work intends to go beyond this drawback presenting an accurate investigation of sol-gel TiO2 NPs shaped as spheres and rods. They have been fully characterized by complementary analytical techniques both suspended in apolar solvents, by dynamic light scattering (DLS) and nuclear magnetic resonance (NMR) and after deposition on substrates (solid state configuration) by transmission electron microscopy (TEM) and powder x-ray diffraction (PXRD). In the case of suspended anisotropic rods, the experimental DLS data, analyzed by the Tirado-Garcia de la Torre model, present the following ranges of dimensions: 4-5 nm diameter (?) and 11-15 nm length (L). These results are in good agreement with that obtained by the two solid state techniques, namely 3.8(9) nm ? and 13.8(2.5) nm L from TEM and 5.6(1) ? and 13.3(1) nm L from PXRD data. To prove the suitability of the supported sol-gel NPs for biological issues, spheres and rods have been separately deposited on coverslips. The cell response has been ascertained by evaluating the adhesion of the epithelial cell line Madin-Darby canine kidney. The cellular analysis showed that titania films promote cell adhesion as well clustering organization, which is a distinguishing feature of this type of cell line. Thus, the use of nanostructured substrates via sol-gel could be considered a good candidate for cell culture with the further advantages of likely scalability and interfaceability with many different materials usable as supports. PMID- 29176063 TI - Silicon surface passivation by PEDOT: PSS functionalized by SnO2 and TiO2 nanoparticles. AB - In this paper, we present a study of silicon surface passivation based on the use of spin-coated hybrid composite layers. We investigate both undoped poly(3,4 ethylenedioxythiophene)/poly-(styrenesulfonate) (PEDOT:PSS), as well as PEDOT:PSS functionalized with semiconducting oxide nanomaterials (TiO2 and SnO2). The hybrid compound was deposited at room temperature by spin coating-a potentially lower cost, lower processing time and higher throughput alternative compared with the commonly used vacuum-based techniques. Photoluminescence imaging was used to characterize the electronic properties of the Si/PEDOT:PSS interface. Good surface passivation was achieved by PEDOT:PSS functionalized by semiconducting oxides. We show that control of the concentration of semiconducting oxide nanoparticles in the polymer is crucial in determining the passivation performance. A charge carrier lifetime of about 275 MUs has been achieved when using SnO2 nanoparticles at a concentration of 0.5 wt.% as a filler in the composite film. X-ray diffraction (XRD), scanning electron microscopy, high resolution transmission electron microscopy (HRTEM), energy dispersive x-ray in an SEM, and MU-Raman spectroscopy have been used for the morphological, chemical and structural characterization. Finally, a simple model of a photovoltaic device based on PEDOT:PSS functionalized with semiconducting oxide nanoparticles has been fabricated and electrically characterized. PMID- 29176064 TI - Broad-band antireflective pore-like sub-wavelength surface nanostructures on sapphire for optical windows. AB - Compared with conventional antireflective film, antireflective sub-wavelength surface structure provides an ideal choice for sapphire optical window especially in harsh environments. However, it is still a challenge to obtain sapphire antireflective surface microstructure because of its high hardness and chemical inertness. In this paper, combined with optical simulation, we proposed a facile method based on the anodic oxidation of aluminum film and following epitaxial annealing. Al thin film was deposited on sapphire substrate by magnetron sputtering, and anodic oxidation was then performed to prepare surface pore-like structures on the Al film. Followed by two-step annealing, both the anodic oxidized coating and underlying unoxidized Al film were transformed totally into alumina. The parameters of anodic oxidation were analyzed to obtain the optimal pore-like structures for the antireflection in the mid-infrared and visible spectrum regions, respectively. Finally, the optimized surface sub-wavelength nanostructure on sapphire can increase the transmittance by 7% in the wavelength range of 3000~5000 nm and can increase 13.2% significantly for visible spectrum region, respectively. Meanwhile, the surface wettability can be also manipulated effectively. The preparation of surface pore-like sub-wavelength structure by the annealing of anodic oxidized aluminum film on sapphire is a feasible, economical and convenient approach and can find the applications for various optoelectronic fields. PMID- 29176065 TI - Vertical MoSe2-MoO x p-n heterojunction and its application in optoelectronics. AB - The hybrid n-type 2D transition-metal dichalcogenide (TMD)/p-type oxide van der Waals (vdW) heterojunction nanosheets consist of 2D layered MoSe2 (the n-type 2D material) and MoO x (the p-type oxide) which are grown on SiO2/Si substrates for the first time via chemical vapor deposition technique, displaying the regular hexagon structures with the average length dimension of sides of ~8 MUm. Vertical MoSe2-MoO x p-n heterojunctions demonstrate obviously current-rectifying characteristic, and it can be tuned via gate voltage. What is more, the photodetector based on vertical MoSe2-MoO x heterojunctions displays optimal photoresponse behavior, generating the responsivity, detectivity, and external quantum efficiency to 3.4 A W-1, 0.85 * 108 Jones, and 1665.6%, respectively, at V ds = 5 V with the light wavelength of 254 nm under 0.29 mW cm-2. These results furnish a building block on investigating the flexible and transparent properties of vdW and further optimizing the structure of the devices for better optoelectronic and electronic performance. PMID- 29176066 TI - Solvent-free nanofluid with three structure models based on the composition of MWCNTs/SiO2 core and its adsorption capacity of CO2. AB - A series of core/shell nanoparticle organic/inorganic hybrid materials (NOHMs) with different weight ratios of two components, consisting of multi-walled carbon nanotubes (MWCNTs) and silicon dioxide (SiO2) as the core had been synthesized. The NOHMs displays a liquid-like state in the absence of solvent at room temperature. Five NOHMs were categorized into three kinds of structure states based on different weight ratio of two components in core, named power strip model, critical model and collapse model. The capture capacities of these NOHMs for CO2 were investigated at 298 K and CO2 pressures ranging from 0 to 5 MPa. Compared with NOHM having neat MWCNTs core, it had been revealed that NOHMs with power strip model show better adsorption capacity toward CO2, due to its lower viscosity and more reactive groups that can react with CO2. In addition, the capture capacities of NOHMs with critical model were relatively worse than neat MWCNTs-based NOHM. The result is attributed to the aggregation of SiO2 in these samples, which may cause the consumption and hindrance of reactive groups. However, the capture capacity of NOHM with collapse model was the worst in all NOHMs, owing to its lowest content of reactive groups and hollow structure in MWCNTs. Besides, it presented non-interference of MWCNTs and SiO2 without aggregation state. PMID- 29176067 TI - Characterization of a prototype MR-compatible Delta4 QA system in a 1.5 tesla MR linac. AB - To perform patient plan quality assurance (QA) on a newly installed MR-linac (MRL) it is necessary to have an MR-compatible QA device. An MR compatible device (MR-Delta4) has been developed together with Scandidos AB (Uppsala, Sweden). The basic characteristics of the detector response, such as short-term reproducibility, dose linearity, field size dependency, dose rate dependency, dose-per-pulse dependency and angular dependency, were investigated for the clinical Delta4-PT as well as for the MR compatible version. All tests were performed with both devices on a conventional linac and the MR compatible device was tested on the MRL as well. No statistically significant differences were found in the short-term reproducibility (<0.1%), dose linearity (?0.5%), field size dependency (<2.0% for field sizes larger than 5 * 5 cm2), dose rate dependency (<1.0%) or angular dependency for any phantom/linac combination. The dose-per-pulse dependency (<0.8%) was found to be significantly different between the two devices. This difference can be explained by the fact that the diodes in the clinical Delta4-PT were irradiated with a much larger dose than the MR-Delta4 PT ones. The absolute difference between the devices (<0.5%) was found to be small, so no clinical impact is expected. For both devices, the results were consistent with the characteristics of the Delta4-PT device reported in the literature (Bedford et al 2009 Phys. Med. Biol. 54 N167-76; Sadagopan et al 2009 J. Appl. Clin. Med. Phys. 10 2928). We found that the characteristics of the MR compatible Delta4 phantom were found to be comparable to the clinically used one. Also, the found characteristics do not differ from the previously reported characteristics of the commercially available non-MR compatible Delta4-PT phantom. Therefore, the MR compatible Delta4 prototype was found to be safe and effective for use in the 1.5 tesla magnetic field of the Elekta MR-linac. PMID- 29176068 TI - Role of interbranch pumping on the quantum-statistical behavior of multi-mode magnons in ferromagnetic nanowires. AB - Theoretical studies are reported for the quantum-statistical properties of microwave-driven multi-mode magnon systems as represented by ferromagnetic nanowires with a stripe geometry. Effects of both the exchange and the dipole dipole interactions, as well as a Zeeman term for an external applied field, are included in the magnetic Hamiltonian. The model also contains the time-dependent nonlinear effects due to parallel pumping with an electromagnetic field. Using a coherent magnon state representation in terms of creation and annihilation operators, we investigate the effects of parallel pumping on the temporal evolution of various nonclassical properties of the system. A focus is on the interbranch mixing produced by the pumping field when there are three or more modes. In particular, the occupation magnon number and the multi-mode cross correlations between magnon modes are studied. Manipulation of the collapse and revival phenomena of the average magnon occupation number and the control of the cross correlation between the magnon modes are demonstrated through tuning of the parallel pumping field amplitude and appropriate choices for the coherent magnon states. The cross correlations are a direct consequence of the interbranch pumping effects and do not appear in the corresponding one- or two-mode magnon systems.

AB - As is well known, the lower durability and sluggish methanol oxidation reaction (MOR) of PtRu alloy electrocatalyst blocks the commercialization of direct methanol fuel cells (DMFCs). Here, we design a new PtRu electrocatalyst, with highly stable CO tolerance and durability, in which the PtRu nanoparticles are embedded in nitrogen doped carbon layers derived from carbonization of poly(vinyl pyrrolidone). The newly fabricated electrocatalyst exhibits no loss in electrochemical surface area (ECSA) and MOR activity after potential cycling from 0.6-1.0 V versus reversible hydrogen electrode, while commercial CB/PtRu retains only 50% of its initial ECSA. Meanwhile, due to the same protective layers, the Ru dissolution is decelerated, resulting in stable CO tolerance. Methanol oxidation reaction (MOR) testing indicates that the activity of newly fabricated electrocatalyst is two times higher than that of commercial CB/PtRu, and the fuel cell performance of the embedded PtRu electrocatalyst was comparable to that of commercial CB/PtRu. The embedded PtRu electrocatalyst is applicable in real DMFC operation. This study offers important and useful information for the design and fabrication of durable and CO tolerant electrocatalysts. PMID- 29176070 TI - A facile single-step synthesis of polyvinylpyrrolidone-silver nanocomposites using a conventional spray dryer. AB - We have developed a facile single-step synthesis of silver nanocomposite using a conventional spray dryer. We investigated the synthetic conditions by controlling the concentrations of the chemical reactants. Further, we confirmed the effect of the molecular weight of polyvinylpyrrolidones, and revealed that the molecular weight significantly affected the properties of the resultant silver nanocomposites. The long-term stability of the silver nanocomposites was tested, and little change was observed, even after storage for three months. Most of all, the simple commercial implementation, in combination with large-scale synthesis, possesses a variety of advantages, compared to conventional complicated and costly dry-process synthesis methods. Thus, our method presents opportunities for further investigation, for both lab-scale studies and large-scale industrial applications. PMID- 29176071 TI - Thermodynamics of two-impurity Anderson model with Dzyaloshinskii-Moriya interaction. AB - In this work, we use the numerical renormalization group (NRG) theory to study the thermodynamics of the two-impurity Anderson model. Two different methods are used to estimate the effect of Dzyaloshiskii-Moriya (DM) interaction on the variation of the Kondo temperature. When the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction is vanishing, the two different estimations give different tendencies. If we use the peak of the specific heat to identify the variation of the Kondo temperature versus the DM interaction, we get an almost linear function. However, if we use the low temperature universal curve of the impurity entropy, we get a quadratic function. These results indicate that previous debates about the influence of spin-orbit coupling on the Kondo temperature may come from the different definitions of the Kondo temperature. When the RKKY interaction is ferromagnetic, there are two stages of Kondo screening. Both estimations demonstrate that the second stage of the Kondo temperature is exponentially dependent on the DM interaction. There results are dramatically different from those calculated via perturbation theory. PMID- 29176072 TI - Diagnostic reference levels and optimisation in radiology: where do we go from here?

AB - The experience accumulated while dealing with the aftermath of a major nuclear accident (the 'Kyshtym Accident') in 1957 at the Mayak complex in the Southern Urals of Russia is summarised. Information is presented on the causes of the accident, on the radiation environment and radioactive contamination of the affected territory in the critical period, and on the system of emergency management and decision-making adopted when dealing with the accident and its aftermath. The technical and organisational approaches applied and methods used are described, as well as remediation results and the current situation 60 years after the accident. It is demonstrated that the implementation of fairly simple and self-evident organisational and technical solutions gave good results, and that appropriate timely and task-oriented measures were applied. Safety relevant conclusions and recommendations are presented. PMID- 29176074 TI - Validation and uncertainty analysis of a pre-treatment 2D dose prediction model. AB - Independent verification of complex treatment delivery with megavolt photon beam radiotherapy (RT) has been effectively used to detect and prevent errors. This work presents the validation and uncertainty analysis of a model that predicts 2D portal dose images (PDIs) without a patient or phantom in the beam. The prediction model is based on an exponential point dose model with separable primary and secondary photon fluence components. The model includes a scatter kernel, off-axis ratio map, transmission values and penumbra kernels for beam delimiting components. These parameters were derived through a model fitting procedure supplied with point dose and dose profile measurements of radiation fields. The model was validated against a treatment planning system (TPS; Eclipse) and radiochromic film measurements for complex clinical scenarios, including volumetric modulated arc therapy (VMAT). Confidence limits on fitted model parameters were calculated based on simulated measurements. A sensitivity analysis was performed to evaluate the effect of the parameter uncertainties on the model output. For the maximum uncertainty, the maximum deviating measurement sets were propagated through the fitting procedure and the model. The overall uncertainty was assessed using all simulated measurements. The validation of the prediction model against the TPS and the film showed a good agreement, with on average 90.8% and 90.5% of pixels passing a (2%,2 mm) global gamma analysis respectively, with a low dose threshold of 10%. The maximum and overall uncertainty of the model is dependent on the type of clinical plan used as input. The results can be used to study the robustness of the model. A model for predicting accurate 2D pre-treatment PDIs in complex RT scenarios can be used clinically and its uncertainties can be taken into account. PMID- 29176075 TI - Detection of surface-EMG activity from the extensor digitorum brevis muscle in healthy children walking. AB - OBJECTIVE: The purpose of the study was the assessment of activation patterns of the extensor digitorum brevis (EDB) muscle in healthy children, during walking at self-selected speed and cadence. APPROACH: To this end, statistical gait analysis was performed on surface electromyographic (sEMG) signals of the EDB, in a large number (hundreds) of strides per subject. sEMG data from the tibialis anterior (TA) and gastrocnemius lateralis (GL) were also investigated for comparative purposes. MAIN RESULTS: Results from 23 healthy children showed a large variability in the number of muscle activations, occurrence frequency, and onset offset instants across considered strides. The assessment of different modalities of muscle activation allowed the identification of a single activity pattern, common to all the modalities and we were able to characterize the behavior of the EDB during the gait of healthy children. The pattern of EDB activity centered in two main regions of the gait cycle: in the second half of the stance phase (detected in 100% of subjects) and in the final swing phase (50%). Comparison with the TA and GL regions of activity suggested that the EDB and TA worked mainly as antagonist muscles for the ankle joint, while the EDB and GL did not oppose each other in action, but acted in synergy for the control of the ankle joint during walking. SIGNIFICANCE: The 'Normality' pattern for the EDB activity reported here represents the first attempt to develop a reference for dynamic sEMG of the EDB in healthy children, enabling us to include the physiological variability of the phenomenon. Present results could be useful for discriminating physiological and pathological behavior in children and for deepening the maturation of the gait. PMID- 29176076 TI - Electrocatalytic CO2 reduction near the theoretical potential in water using Ru complex supported on carbon nanotubes. AB - We successfully developed a highly efficient electrode for CO2 reduction using a Ru-complex catalyst ([Ru]) supported on carbon paper coated with multi-walled carbon nanotubes (CPCNT/[Ru]). The CPCNT/[Ru] electrode promoted the CO2 reduction reaction in aqueous solution near the theoretical potential, and produced formate linearly with a current density of greater than 0.9 mA cm-2 at 0.15 V (versus RHE) for at least 24 h. Due to the outstandingly low overpotential, a monolithic tablet-shaped photo-device was realized by coupling the CPCNT/[Ru] catalyst with amorphous SiGe-jn as a light absorber and IrO x as a water oxidation catalyst, and the device produced formate from CO2 and water in a single-compartment reactor. The nanotubes enhanced the rate for CO2 reduction at [Ru], and accordingly a solar-to-chemical conversion efficiency of 4.3% for formate production was achieved when the CO2 reduction and H2O oxidation sites had the same area. PMID- 29176077 TI - Erythrocyte membrane-coated Gold nanocages for targeted cancer photothermal and chemical therapy. AB - Recently, RBC membrane coated nanoparticles have attracted much attention because of their excellent immune escape ability; meanwhile, Au nanocages (AuNs) have been extensively used for cancer therapy due to its photothermal effect and drug delivery capability. The combination of RBC membrane coating and Au nanocages may provide an effective approach for targeted cancer therapy. However, few reports have shown the utilization of combining these two technologies. Here, we present the development of Erythrocyte membrane-coated Gold nanocages for targeted cancer photothermal and chemical therapy. First, anti-EpCam antibodies are used to modify RBC membranes to target 4T1 cancer cells. Second, the antitumor drug paclitaxel is encapsulated into AuNs. Then, the AuNs are coated with the modified RBC membranes. This new nanoparticles are termed EpCam-RPAuNs. We characterize the capability of EpCam-RPAuNs for selective tumor targeting via exposure to the near-infrared irradiation. Experimental results demonstrate that EpCam-RPAuNs can effectively generate hyperthermia and precisely deliver the antitumor drug PTX to targeted cells. We also validate the biocompatibility of our EpCam-RPAuNs in vitro. By combining the targeting moleculars modified RBC membrane and AuNs, our approach provides a new way to design biomimetic nanoparticles to enhance the surface functionality of nanoparticles. We believe that EpCam-RPAuNs can be potentially applied for cancer diagnoses and therapies. PMID- 29176078 TI - One stage surgery for synchronous liver metastasis from a neuroendocrine tumor of the colon. A case report. AB - INTRODUCTION: Neuroendocrine tumors (NETs) are a heterogeneous group of tumors. NET of colon represent less than 1% of colonic tumors. Synchronous liver metastases, present in 75-80%, are considered significant adverse prognostic indicators. Liver is the second commonest site for metastasis in patients with colorectal neuroendocrine tumors. Available treatment options include surgical resection, chemotherapy, biotherapy. Surgery is the gold standard for curative therapy and it is strictly related to the localization, the grade of tumor, and the stage of disease. CASE REPORT: We present a 64-year-old man with clinical carcinoid syndrome. Colonoscopy revealed ileocecal valve vegetating mass with negative biopsy. CT scans of thorax and abdomen showed a voluminous lesion (10 cm of diameter) of right liver. CEA, CA 19.9 and aFP were all normal. Only urinary 5HIAASerum 5-hydroxyindoleactic acid and blood Chromogranin A were positive. Surgical strategy was to treat the primary tumor and the liver synchronous metastasis in one stage surgery. DISCUSSION: Management of NETs liver metastases is challenging and requires aggressive therapy. Currently, there are many therapeutic options for metastatic NETs. Although complete surgical resection remains the optimal therapy and aggressive surgical resection increases the 5 year survival of NETs with solitary liver metastasis to 100%. In this case, clinical status with doubt of carcinoid syndrome was essential for diagnosis and for subsequent surgical strategy with one stage surgery. CONCLUSION: Resection of the primary tumor, liver metastases, and local mesenteric lymph node metastases is thought to strictly promote long-term survival and quality of life. Typically, a multidisciplinary approach is a cornerstone for decision making while dealing with this aggressive disease. KEY WORDS: Carcinoid syndrome, Liver surgery, NETs, Neuroendocrine tumor, One stage surgery, Synchronous liver metastasis. PMID- 29176079 TI - If the Framingham Heart Study Did Not Invent the Risk Factor, Who Did? AB - Most historians, epidemiologists, and physicians credit the Framing-ham Heart Study for introducing the term "risk factor" to public health and medicine. Many add that the term came from life insurance companies. This familiar history is incorrect. Taking advantage of the expanding availability of digitized and full text searchable journals, textbooks, newspapers, and other sources, we have uncovered a deeper and broader history. Antecedent concepts (such as risk, factor, predisposition) have ancient roots. "Risk factor" began to appear in the late 19th and early 20th centuries in many industries, not just in insurance but also in finance, agriculture, and manufacturing. The term appeared in the occupational health literature in 1922. It reappeared in the 1950s in many different areas of medicine including psychiatry, surgery, cardiology, epidemiology, and aerospace medicine. Furthermore, despite the influential appearance of "risk factor" in a 1961 Framingham Heart Study publication, the term did not gain momentum in medicine and public health until the mid-1970s. While our analysis is not exhaustive, our findings are extensive enough to require a substantial revision to the history of the risk factor. PMID- 29176080 TI - The Etiological Stance: Explaining Illness Occurrence. AB - Kelly, Kelly, and Russo (2014) recently proposed to integrate biological, behavioral, and social mechanisms into "mixed mechanisms" situated in the individual's "lifeworld" when considering illness causation. This article suggests considering terminological discrepancies, replacing the pathogenetic with an etiological perspective (that includes, but is not limited to pathogenesis), and rethinking whether the lifeworld concept adds to what we consider an individual's "environment." It also proposes replacing the notion of "mixed mechanisms" with the concept of "combined contributions" of factors in etiological explanations of illness. PMID- 29176081 TI - Biocontaining: Purification, Restoration, and Meaning-Making. AB - Biocontaining during the recent Ebola outbreak served to affirm the social significance of biomedicine, even though it had little measurable effect on the pandemic itself. Taking up key insights of Mary Douglas and Victor Turner concerning the essential meaning-making tasks of culture, this article discusses how biocontaining as an activity contributed to the work of social reassurance and meaning-making in U.S. and global society during the crisis. The analysis is based in significant part on fieldwork done at the Nebraska Biocontainment Unit (NBU), study of NBU educational materials, and follow-up conversations with personnel staffing that unit. PMID- 29176082 TI - The Best Interest Standard: Same Name but Different Roles in Pediatric Bioethics and Child Rights Frameworks. AB - This article explores the intersection of pediatric bioethics and child rights by examining the best interest standard as it operates within the pediatric bioethics framework in the United States and the child rights framework based on the UN 1989 Convention on the Rights of the Child (CRC). While the "best interest of the child" standard is central to both pediatric bioethics and the child rights community, it operates only as a guidance principle, and not as an intervention principle, in decision-making within U.S. pediatric bioethics, whereas it operates as both a guidance and intervention principle in the child rights community. The differences in how the best interest standard is operationalized lead to different roles for the family, the state, and the minor in decision-making processes and outcomes. We examine the recent case of Charlie Gard to illustrate some of these differences. PMID- 29176083 TI - Marston Bates, Visionary Environmentalist. AB - Marston Bates (1906-1974) raised questions concerning man's relationship to nature, questions that are of much greater importance today than they were during his lifetime. He began his career with the Rockefeller Foundation as a mosquito expert, and by 1955 he had established himself as one of the key players in the field of human ecology through a series of publications that brought together in a clear and readable style the complexities involved in understanding human ecology. This article traces Bates's development and discusses how the Foundation failed to engage the subject of human ecology, even at a time when it recognized its critical importance to humankind. PMID- 29176084 TI - A Child's Right to Be Well Born: Venereal Disease and the Eugenic Marriage Laws, 1913-1935. AB - An extensive literature describes the legal impact of America's eugenics movement, and the laws mandating sterilization, restriction of marriage by race, and ethnic bans on immigration. But little scholarship focuses on the laws adopted in more than 40 states that were commonly referred to as "eugenic marriage laws." Those laws conditioned marriage licenses on medical examinations and were designed to save innocent women from lives of misery, prevent stillbirth or premature death in children, and save future generations from the myriad afflictions that accompanied "venereal infection." Medical journals, legal journals, and every kind of public press outlet explained the "eugenic marriage laws" and the controversies they spawned. They were inextricably bound up in reform movements that attempted to eradicate prostitution, stamp out STIs, and reform America's sexual mores in the first third of the 20th century. This article will explain the pedigree of the eugenic marriage laws, highlight the trajectory of Wisconsin's 1913 eugenic enactment, and explore how the Wisconsin Supreme Court case upholding the law paved the way for the majority of states to regulate marriage on eugenic grounds.

AB - Regardless of one's religious beliefs, the process of making end-of-life decisions is inherently difficult and emotionally trying. The caregiver, family member, or friend is faced with making heart-wrenching decisions for loved ones where the line between support and cruelty may feel blurred. By evaluating the process by which traditional Judaism harmonizes the apparently conflicting obligations of the caregiver in end-of-life scenarios through three practical cases, all people can gain insight into managing this delicate balancing act and may develop generalizable approaches that recognize and appreciate the particularities of each patient's needs. The traditional Orthodox Jewish approach to terminal illness is guided by defined legal principles that facilitate greater understanding and promote more empathetic care for Jewish patients. PMID- 29176086 TI - Choosing to Care for Children Who Might Die: Conversations with Pediatric Residents. AB - This essay evolved from observations that pediatric resident physicians' experiences with patient deaths might influence their career paths after completing residency training. The author's journey as a physician led her to wonder whether young pediatricians who gravitated toward careers in primary care had qualitatively different experiences with death and dying during their medical training compared to those who chose fields in which they were more likely to confront death and dying on a regular basis, such as pediatric critical care, neonatology, or pediatric oncology. Ten pediatric residents agreed to participate in conversations that were then expanded to encompass related concepts of "devastating diagnoses" and of "giving bad news." Three central themes-the privilege of supporting families through difficult times, the challenge of navigating between expectations and uncertainty, and the resilience of children experiencing illness-emerged as having profoundly influenced pediatricians' understanding of their professional journeys and identities. PMID- 29176087 TI - In Pursuit of Educational Integrity: Professional Identity Formation in the Harvard Medical School Cambridge Integrated Clerkship. AB - Graduates of Harvard Medical School's Cambridge Integrated Clerkship (CIC) describe several core processes that may underlie professional identity formation (PIF): encouragement to integrate pre-professional and professional identities; support for learner autonomy in discovering meaningful roles and responsibilities; learning through caring relationships; and a curriculum and an institutional culture that make values explicit. The authors suggest that the benefits of educational integrity accrue when idealistic learners inhabit an educational model that aligns with their own core values, and when professional development occurs in the context of an institutional home that upholds these values. Medical educators should clarify and animate principles within curricula and learning environments explicitly in order to support the professional identity formation of their learners. PMID- 29176088 TI - Hope and Resentment. AB - A common challenge for both health-care providers and policymakers is to deal with people as people, rather than merely as biological or social problems to be managed. In terms introduced in P. F. Strawson's much-discussed essay "Freedom and Resentment" (1962), the difficulty is to maintain a reactive "participant stance," rather than a solely objective perspective, toward those with whom they have difficulties. Vaccine resistance and refusal provides a particularly pointed instance of this challenge: there is evidence that suggests standard methods of rational persuasion tend to be ineffective, even counter-productive, in easing skepticism about the safety, effectiveness, or appropriateness of vaccines and vaccine regimens. If clear and vivid information about relative risks is not compelling, the temptation to manipulate rather than convince skeptics may be hard, or even seem wrong, to resist. Mark Navin's recent Values and Vaccine Refusal (2016) can be read as a reminder of the importance-and the difficulty-of maintaining a participant stance toward vaccine deniers or resisters.

AB - In his 2015 book Pain: A Political History, Keith Wailoo demonstrates how a medicalized condition became central to defining party politics in the United States from World War II down to the present. Drawing on sources ranging from postwar Congressional hearings concerning the veteran welfare state to debates surrounding Rush Limbaugh's OxyContin addiction, Wailoo offers a fresh analysis of both U.S. political history and medical history, showing how today's highly polarized party system emerged in part from debates surrounding the existence and worth of pain, as well as its management.

AB - Chronic kidney disease is a non-communicable disease that is now well recognized as a major source of premature morbidity and mortality. In general, racial/ethnic minorities in the United States are more likely than non-minority groups to develop end-stage renal disease (ESRD), but paradoxically most have a lower mortality risk. Unlike most minorities, dialysis patients in Puerto Rico have a mortality risk nearly 50% higher than the national average. Multiple factors such as medical conditions, socioeconomic, environmental, and health system factors can influence health outcomes for patients with ESRD. We describe one potential health system factor that may contribute to this finding, a unique interpretation and implementation of the ESRD Medicare Secondary Payer provision in the Commonwealth of Puerto Rico. We conducted a search of regulatory documents and key stakeholder interviews to help envision the potential implications of these differences for dialysis facilities, health care providers, and patients with ESRD.

AB - In the United States (U.S.), health care policy plays a critical role in ensuring adequate care for people living with HIV (PLWH), eliminating new HIV infections, and reducing health disparities. The 2010 Patient Protection and Affordable Care Act (ACA) was designed to make health care more accessible, of higher quality, and more affordable. Many provisions of the ACA are considered relevant to HIV care and prevention. Because PLWH have unique care needs and many groups at risk for infection are members of vulnerable populations, timely and comprehensive evaluation of the ACA in terms of HIV is critical. In this paper, we discuss components of the ACA relevant to HIV care and prevention, describe their anticipated and initial effects, and finally, outline a research agenda to inform future HIV programming and policy.

PMID- 29176095 TI - Assessing Health Care Access and Use among Indigenous Peoples in Alberta: a Systematic Review. AB - Alberta's Indigenous population is growing, yet health care access may be limited. This paper presents a comprehensive review on health care access among Indigenous populations in Alberta with a focus on the health care services use and barriers to health care access. Scientific databases (PubMed, EMBASE, CINAHL, and PsycINFO) and online search engines were systematically searched for studies and grey literature published in English between 2000 and 2013 examining health care services access, use and barriers to access among Indigenous populations in Alberta. Information on health care services use and barriers to use or access was synthesized based on the MOOSE guidelines. Overall, compared to non Indigenous populations, health care use rates for hospital/emergency room services were higher and health care services use of outpatient specialists was lower among Indigenous peoples. Inadequate numbers of Indigenous health care professionals; a lack of cross-cultural training; fear of foreign environments; and distance from family and friends were barriers to health care use and access. Inequity in social determinants of health among Indigenous peoples and inadequate "health services with prevention approaches," may contribute to present health disparities between Indigenous and non-Indigenous populations in the province. PMID- 29176096 TI - Short Sleep Duration is Associated with Obesity in Hispanic Manufacturing Workers. AB - The present study examined the relationship between obesity and sleep duration among Hispanic manufacturing workers. Two hundred and twenty eight Hispanic workers from eight manufacturing plants completed an in-person interview that included measures of demographics, health literacy, and sleep duration. Height and weight were directly assessed. A logistic regression, controlling for gender, education, age, income, physical activity levels, self-reported health status, and health literacy, indicated that workers who slept six hours or less were significantly more likely to be obese than those sleeping seven to nine hours (OR: 1.90, 95% CI: 1.04-3.47). Our results extend previous research on the association between sleep duration and obesity to an understudied population of Hispanic workers. PMID- 29176097 TI - Access to Health Care among Mexican Migrants and Immigrants: A Comparison across Migration Phases. AB - OBJECTIVES: We examined differences in, and factors associated with, access to health services among Mexican im/migrants to the U.S. across migration phases, including pre-departure, destination, interception, and return. METHODS: Using data from a cross-sectional survey conducted in Tijuana, Mexico (N = 1,541), we computed descriptive statistics and staged logistic regressions to estimate health care access indicators and factors associated with access to services. RESULTS: Im/migrants at post-migration phases had lower likelihood of receiving health care and having a usual source of care, and higher rates of forgone care, than their counterparts at pre-departure. These differences were partly explained by length of migration phase, health insurance status, transportation barriers, and detention or imprisonment. CONCLUSIONS: Mexican im/migrants face challenges in accessing health services across the migration continuum, especially at post migration phases. Binational efforts to provide affordable insurance coverage and reduce transportation limitations and incarceration could contribute to improving health care access among Mexican im/migrants. PMID- 29176098 TI - Incidence of Non-Melanoma Skin Cancer in the Uninsured. AB - Non-melanoma skin cancer (NMSC) is a common reason for outpatient primary care visits. Uninsured patients may be at a higher risk for NMSC due to lack of access to health care and a possible increased risk of sun exposure due to insecure housing. The true incidence of NMSC in this population is unknown. In order to determine the population's incidence of NMSC we performed a retrospective chart review on all patients (n = 656) seen at the Lubbock Impact Free Clinic from July 1, 2014 through July 30, 2015. This highlighted an increased incidence of NMSC in our uninsured population (1.4% [9/656]), particularly in the 50-64 age range (2.8% [7/250]) when compared with the general United States population (0.65% 1.05%). We believe that skin care education and routine skin cancer screening should be emphasized in the care of these patients due to their increased risk.

AB - BACKGROUND: Little is known about real-world outcomes for new interferon-free treatment for hepatitis C virus (HCV) among underserved and diverse communities. OBJECTIVE: To identify predictors of treatment prescription and evaluate outcomes as measured by sustained virologic response (SVR) with HCV RNA testing three months after therapy completion. DESIGN: Retrospective cohort at a safety-net health care system. PARTICIPANTS: Patients with (1) at least one clinical visit between December 6, 2013, and December 31st 2014; and (2) at least three months follow-up. KEY RESULTS: Predominantly non-White cohort (61%). Of 1,284 HCV infected patients 121 prescribed sofosbuvir-based therapy. Severe liver fibrosis (OR 1.66, 95% CI 1.05, 2.64) independently associated with treatment prescription. In those with evaluable HCV RNA, SVR was 99%. CONCLUSION: Cure rates similar to clinical trial data can be achieved in diverse underserved communities. PMID- 29176100 TI - Utilization and Cost Analysis of a Chronically Ill, Newly Insured Indigent Population. AB - The Affordable Care Act expanded health insurance for low-income, uninsured individuals. Few longitudinal analyses have investigated how insurance expansion influences cost and utilization among adults with chronic conditions. This study conducted longitudinal analysis investigating time trends in utilization and cost among newly insured, chronically ill, low-income individuals using Generalized Estimating Equations models. For hospitalization, hospital outpatient services, emergency department (ED) visits, and primary care visits, two indicators were measured: the proportion of enrollees with services and the average number of visits among users. The average health expenditure per person was estimated using a gamma distribution. Results indicate that the number of individuals using inpatient or ED services was highest during the first six months following insurance coverage and decreased in subsequent periods, while primary care visits increased during the first year. Using six-month rather than annual measures of utilization and cost may be necessary to identify short-run changes following initial insurance coverage. PMID- 29176101 TI - Indian Health Service Coverage among American Indians and Alaska Natives in Federal Tribal Areas. AB - Compared with other racial/ethnic groups, American Indians and Alaska Natives (AIANs) have higher uninsured rates and worse health outcomes. Using data from the 2010-2014 American Community Survey, we employ logistic regression techniques to assess the characteristics associated with Indian Health Service (IHS) coverage among working-age AIANs who have health insurance or are uninsured. Across all insurance categories, geographic residence is a factor in IHS coverage. Among the uninsured, those with and without IHS coverage are more dissimilar than similar across socioeconomic characteristics. When controlling for confounding characteristics, people who are uninsured or have Medicaid have a much higher IHS coverage rate compared with those with employer-sponsored insurance. This indicates IHS coverage is an important component for the uninsured and it complements Medicaid services. This work identifies a need for increased outreach to eligible AIANs about IHS programs, particularly those without comprehensive care. PMID- 29176102 TI - Quality Health Care for Homeless Children: Achieving the AAP Recommendations for Care of Homeless Children and Youth. AB - BACKGROUND: We assessed whether and how health care organizations serving homeless pediatric patients meet recommendations issued by the American Academy of Pediatrics (AAP). METHODS: We conducted a web-based survey of Health Care for the Homeless (HCH) Program grantees serving children. RESULTS: Of 169 grantees, 77 (46%) responded. All organizations reported connecting patients to specialty services. Nearly all reported screening for homelessness (90%), facilitating Medicaid enrollment (90%), connecting patients to benefits (94%), addressing underlying causes of homelessness (83%), assisting with transportation (83%), and knowing about the causes of homelessness (76%). Fewer reported integrating comprehensive care into acute visits (61%) or having medical-legal partnerships (57%). Federally qualified health center status was associated with meeting more recommendations. We described barriers and facilitators to meeting recommendations. DISCUSSION: Health care organizations serving homeless children largely meet AAP recommendations, but integrating comprehensive care into acute visits remains an area for improvement. Disseminating best practices may support guideline adherence. PMID- 29176103 TI - Neonatal Abstinence Syndrome in East Tennessee: Characteristics and Risk Factors among Mothers and Infants in One Area of Appalachia. AB - OBJECTIVE: To describe the epidemiology of neonatal abstinence syndrome (NAS) in a 16-county Appalachian area of eastern Tennessee. METHODS: The Tennessee Surveillance System for NAS provided data on maternal sources of opioids. Data linking hospital discharge diagnosis for NAS to birth certificate data allowed us to compare maternal, delivery, and infant characteristics for NAS births with those for non-NAS births. RESULTS: There were 339 cases of NAS in 2013 and 367 in 2014, for NAS rates of 25.5 and 28.5 per 1,000 live births, respectively. When compared with the state overall, mothers of NAS infants in eastern Tennessee were more likely to use opioids that had been prescribed to another person. There were numerous maternal, infant, and delivery characteristics that were significantly different for NAS births compared with non-NAS births. CONCLUSION: Neonatal abstinence syndrome is epidemic in the eastern Tennessee area of Appalachia, with unique maternal and infant characteristics that have important implications for primary, secondary, and tertiary prevention.

Predictor variables included gender, race/ethnicity, and measures of religiosity, spirituality, sense of calling, burnout, and interest in primary care. In bivariate analysis, we found statistically significant associations between our primary outcome variable and gender, spirituality, growing up in MUS, sense of calling, primary care interest, and burnout. All associations except burnout persisted in multivariate analysis. As in studies of physicians, medical student intent to practice in MUS correlated with gender, growing up in MUS, and interest in primary care. Intent correlated with sense of calling and spirituality but not religiosity or burnout. Future research is warranted as spirituality and sense of calling may play a role in career decisions. PMID- 29176105 TI - Frailty Assessment in Patients Utilizing a Free Clinic. AB - PURPOSE: Frailty is most commonly associated with older adults; however, it has also been identified in vulnerable populations, including homeless adults. Patients who seek health care services in a free clinic often report physical exhaustion, difficulty coping with stressors, chronic disease states, environmental limitations, and a lack of social support, which may contribute to a state of frailty. This pilot study (N = 38) was conducted in adults ages 40-64 years who utilized a free clinic to determine if factors suggestive of frailty were present. METHODS: The Comprehensive Frailty Assessment Instrument (CFAI) was the primary data collection instrument. Anthropometrics and physical performance data were also collected. RESULTS: Physical indicators of frailty were present in 60% of the sample. Psychological, social, and environmental factors affecting health were identified. Sixty-three percent of the participants scored frail or very frail on the CFAI. A larger study is needed to confirm these findings. PMID- 29176106 TI - The Rikers Island Hot Spotters: Exploring the Needs of the Most Frequently Incarcerated. AB - A cohort of frequently incarcerated individuals in the New York City jail system was identified through "hot spotting" analysis. This group demonstrated higher levels of substance use, mental illness, and homelessness than the general jail population, and was typically incarcerated on minor criminal charges. To understand this population better, in-depth interviews (n = 20) were conducted at three Rikers Island correctional facilities with people who had entered the jail system at least 18 times in a six-year period. Findings showed that life circumstances, chronic homelessness, mental illness, and substance use resulted in repeated institutionalization across multiple settings. Participants described an "institutional circuit" that promoted a state of permanent instability characterized by rotating involvement with custodial institutions. Exiting the institutional circuit requires the ability to navigate complex bureaucratic systems; however, without structural reorganization in social service delivery and an emphasis on permanent housing, participants in this group are unlikely to break the cycle. PMID- 29176107 TI - Maternal Health Care Use by Pregnant Women Living with HIV: Factors Associated with Prenatal, Delivery, and Postnatal Care in Haiti. AB - This study compares maternal health care utilization of women living with HIV with that of their HIV-negative peers in Haiti. Data from the 2012-2013 Haiti Demographic and Health Survey were analyzed. Three percent of mothers were HIV positive. These mothers had over two times greater odds than HIV-negative mothers of accessing prenatal care in the first trimester and to deliver in a medical institution, and 1.9 greater odds of having a medical personnel at delivery. Haiti has made progress in increasing maternal health care utilization, specifically in an effort to reduce mother-to-child-transmission of HIV. Haiti's ability to bring institutions together, implement practical policies, and actively engage the most vulnerable pregnant women, those with HIV and those residing in remote areas, may offer valuable insight to similar resource-poor nations seeking to reduce rates of mother-to-child transmission. PMID- 29176108 TI - Oral Health Status of Institutionalized Older Women from Different Socioeconomic Positions. AB - OBJECTIVE: To determine the association between oral health and socioeconomic position in institutionalized older women in Mexico City. METHODS: A cross sectional study was performed in two groups: high socioeconomic position (HSEP), living in a private retirement home, and low socioeconomic position (LSEP), living in a public assistance center. Oral health was determined by edentulism, oral hygiene, healthy teeth, experience of dental caries, missing and filled teeth, gingival bleeding, dental calculus, and periodontal disease. A latent class analysis (LCA) was used to classify oral health status in dentate. RESULTS: Included were 170 women (HSEP 54.1% and LSEP 45.8%), average age 77.3 (SD = 9.3) years. Oral health status was formed: Edentulous 32.4% HSEP and 67.6% LSEP; Class 1 Unfavorable 0% HSEP and 100% LSEP; Class2 Slightly favorable 41.2% HSEP and58.8% LSEP; and Class3 Favorable 84.6% HSEP and 15.4% LSEP. There was a statistically significant association between socioeconomic position (p < .001) and oral health status. CONCLUSIONS: The oral health of women studied was not optimal. Higher socioeconomic position was associated with better oral health status. PMID- 29176109 TI - Routine Screening for Pregnancy Intention to Address Unmet Reproductive Health Needs in Two Urban Federally Qualified Health Centers. AB - OBJECTIVE: The goal of this project was to increase rates of screening for pregnancy intention in primary care. METHODS: Two urban federally qualified health centers with diverse patient populations undertook a quality improvement project to increase rates of routine screening for pregnancy intention among pre menopausal non-pregnant women ages 12-45 without history of sterilization. Responses were recorded in the electronic medical record (EMR). RESULTS: Screening rates of eligible women increased from 0% to 68.3% and from 49.0% to 80.3% at Sites 1 and 2, respectively. Adolescents were screened at lower rates than adults (p < .0001). There was no significant difference in screening rates between English and non-English speaking patients. Project challenges included cultural relevance to certain patient groups, staff turnover, and time for follow up counseling. CONCLUSIONS: Implementation of routine pregnancy intention screening is important to address unmet reproductive health needs, and can be successfully implemented through an EMR regardless of primary language. PMID- 29176110 TI - Enhancing Administrative Data to Predict Emergency Department Utilization: The Role of Neighborhood Sociodemographics. AB - Much of emergency department use is avoidable, and high-quality primary care can reduce it, but performance measures related to ED use may be inadequately risk adjusted. To explore associations between emergency department (ED) use and neighborhood poverty, we conducted a secondary analysis of Massachusetts managed care network data, 2009-2011. For enrollees with commercial insurance (n = 64,623), we predicted any, total, and total primary-care-sensitive (PCS) ED visits using claims/enrollment (age, sex, race, morbidity, prior ED use), network (payor, primary care provider [PCP] type and quality), and census-tract-level characteristics. Overall, 14.6% had any visit; mean visits per 100 persons were 18.8 (+/-0.2) total and 7.6 (+/-0.1) PCS. Neighborhood poverty predicted all three outcomes (all P< .001). Holding providers accountable for their patients' ED use should avoid penalizing PCPs who care for poor and otherwise vulnerable populations. Expected use targets should account for neighborhood-level variables such as income, as well as other risk factors. PMID- 29176111 TI - Dialysis Hospitalization Inequities by Hispanic Ethnicity and Immigration Status. AB - Medicare provides access to chronic outpatient dialysis for most U.S. patients diagnosed with end-stage renal disease. However, many new and/or undocumented immigrants do not qualify due to lawful presence and work credit requirements. Medicare-ineligible dialysis patients often wait until their health is poor enough for admission to emergency room dialysis. We use University of New Mexico Hospital chart data from 2013-2016 for a case-control study measuring the likelihood of being admitted to an emergency room for dialysis among patients who use interpreters, which is employed as a proxy for new and undocumented immigrants, compared with other patients. We find Hispanic patients who use an interpreter are significantly more likely to be admitted to emergency rooms for dialysis compared with patients who did not use an interpreter. This study highlights the need for national, state, and local policies to address this inefficient and inequitable healthcare pattern resulting in unnecessary costs and suffering. PMID- 29176112 TI - Access to Digital Communication Technology and Perceptions of Telemedicine for Patient Education among American Indian Patients with Diabetes. AB - INTRODUCTION: Health care access for medically underserved patients managing chronic conditions is challenging. While telemedicine can support patient education and engagement, the "digital divide" may be particularly problematic among the medically underserved. This study evaluated physical access to digital devices, use of e-mail and social media tools, and perceptions of telemedicine among American Indian (AI) patients with diabetes mellitus (DM). METHODS: Survey data were collected from AI patients with DM during teleophthalmology exams. RESULTS: Eighty-eight percent of patients had access to digital device(s), 70% used e-mail, and 56% used social media. Younger age and greater education were positively associated with e-mail and social media use (p < .05). Most (60%) considered telemedicine an excellent medium for health-related patient education. DISCUSSION: American Indian patients with DM had access enabling patient education via telemedicine. Future work should examine patient technology preferences and effectiveness of technology-based education in improving outcomes among medically underserved populations. PMID- 29176113 TI - Barriers to Health Care among Laotian Americans in Middle Tennessee. AB - We examined barriers to health care among Laotian Americans in a Middle Tennessee community that included a Laotian-speaking practitioner. A Laotian American primary care clinic nurse practitioner surveyed 312 adult Laotian Americans. The dependent variable was whether respondents visited (n = 214, 77.8%) or did not visit (n = 61,22.2%) primary care providers (PCP) in the last year. Chi-square analysis found visiting less likely if respondents were age 18-34 (p < .001), born in U.S. (p < .001), spent less time in U.S. (p = .010), never married (p = .001), lacked health insurance (p < .001), or lacked a PCP (p < .001). Chi-square analysis segmented by age found neither lack of English fluency nor preference for Laotian-speaking providers significantly reduced access, possibly because of the Laotian practitioner. Logistic regression found individuals with insurance five times more likely to visit and individuals with PCP 8.5 times more likely. Results support the value of training minority providers. PMID- 29176114 TI - Adverse Childhood Experiences (ACE) among American Indians in South Dakota and Associations with Mental Health Conditions, Alcohol Use, and Smoking. AB - OBJECTIVES: To assess the prevalence of Adverse Childhood Experiences (ACEs) and their association with behavioral health in American Indian (AI) and non-AI populations in South Dakota. METHODS: We included the validated ACE questionnaire in a statewide health survey of 16,001 households. We examined the prevalence of ACEs and behavioral health conditions in AI and non-AI populations and associations between ACEs and behavioral health. RESULTS: Compared with non-AIs, AIs displayed higher prevalence of ACEs including abuse, neglect, and household dysfunction and had a higher total number of ACEs. For AIs and non-AIs, having six or more ACEs significantly increased the odds for depression, anxiety, PTSD, severe alcohol misuse, and smoking compared with individuals with no ACEs. CONCLUSIONS: American Indians in South Dakota experience more ACEs, which may contribute to poor behavioral health. Preventing and mitigating the effects of ACEs may have a significant impact on health disparities in AI populations. PMID- 29176115 TI - The Cost-effectiveness Analysis of Nurse-Family Partnership in the United States. AB - We evaluated whether Nurse-Family Partnership might serve as a cost-effective social policy for improving health. Using data from studies of randomized controlled trials as well as real-world data, we conducted a Monte Carlo simulation to estimate cost-effectiveness of Nurse-Family Partnership in a hypothetical cohort of first-born children in the United States. Analyses were conducted in 2015. Were all new mothers eligible for Nurse-Family Partnership, the program would produce 0.11 QALYs (95% confidence interval [CI]=0.06, 0.17) at an additional cost of $1,021 (95% CI=-$2,831, $4,414) per nurse-visited child's lifetime relative to the comparison-group children or $14,642 (95% CI = Savings, $71,877) per QALY gained. However, if applied to high-risk mothers, it would generate 0.19 QALYs (95% CI = 0.09, 0.44) and a net benefit of $2,764 (95% CI = $1,210, $7,092) per nurse-visited child. Nurse-Family Partnership should be considered as a policy investment, particularly in an era of investments in the social determinants of health. PMID- 29176118 TI - Flies come through again, period.

AB - BACKGROUND: Vasovagal syncope (VVS) is the most common cause of syncope in children. Neuropeptide Y (NPY) plays an important role in the regulation of blood pressure (BP), as well as myocardial contractility. This study aimed to explore the role of plasma NPY in VVS in children. METHODS: Fifty-six children who were diagnosed with VVS (VVS group) using head-up tilt test (HUT) and 31 healthy children who were selected as controls (control group) were enrolled. Plasma NPY concentrations were detected. The independent t-test was used to compare the data of the VVS group with those of the control group. The changes in plasma NPY levels in the VVS group during the HUT, as well as hemodynamic parameters, such as heart rate (HR), BP, total peripheral vascular resistance (TPVR), and cardiac output (CO), were evaluated using the paired t-test. Furthermore, the correlations between plasma NPY levels and hemodynamic parameters were analyzed using bivariate correlation analysis. RESULTS: The BP, HR, and plasma NPY (0.34 +/- 0.12 pg/ml vs. 0.46 +/- 0.13 pg/ml) levels in the supine position were statistically low in the VVS group compared to levels in the control group (all P < 0.05). Plasma NPY levels were positively correlated with the HR (Pearson, R = 0.395, P < 0.001) and diastolic BP (Pearson, R = 0.311, P = 0.003) when patients were in the supine position. When patients in the VVS group were in the supine position, elevated TPVR (4.6 +/- 3.7 mmHg.min-1.L-1 vs. 2.5 +/- 1.0 mmHg.min-1.L 1, respectively, P < 0.001; 1 mmHg = 0.133 kPa) and reduced CO (1.0 +/- 0.7 L/min vs. 2.4 +/- 1.3 L/min, respectively, P < 0.001) were observed in the positive response period compared with baseline values. The plasma NPY levels were positively correlated with TPVR (Spearman, R = 0.294, P = 0.028) but negatively correlated with CO in the positive-response period during HUT (Spearman, R = 0.318, P = 0.017). CONCLUSIONS: Plasma NPY may contribute to the pathogenesis of VVS by increasing the TPVR and decreasing the CO during orthostatic regulation. PMID- 29176137 TI - Immediate Therapeutic Outcomes and Medium-term Follow-up of Percutaneous Balloon Pulmonary Valvuloplasty in Infants with Pulmonary Valve Stenosis: A Single-center Retrospective Study. AB - BACKGROUND: Percutaneous balloon pulmonary valvuloplasty (PBPV) is the preferred therapy for pulmonary valve stenosis (PVS). This study retrospectively reviewed recent PBPV outcomes in infants with PVS. The aim of this study was to evaluate factors associated with immediate therapeutic outcomes and restenosis during medium-term follow-up. METHODS: The study included 158 infants with PVS who underwent PBPV from January 2009 to July 2015. Demographic characteristics and patient records were reviewed, including detailed hospitalization parameters, hemodynamic data before and immediately after balloon dilation, cineangiograms, and echocardiograms before PBPV and at each follow-up. All procedures were performed by more than two experienced operators. RESULTS: Immediately after balloon dilation, the pressure gradient across the pulmonary valve decreased from 73.09 +/- 21.89 mmHg (range: 43-151 mmHg) to 24.49 +/- 17.00 mmHg (range: 3-92 mmHg; P < 0.001) and the right ventricular systolic pressure decreased from 95.34 +/- 23.44 mmHg (range: 60-174 mmHg) to 52.07 +/- 18.89 mmHg (range: 22-134 mmHg; P < 0.001). Residual transvalvular pressure gradients of 67.31 +/- 15.19 mmHg (range: 50-92 mmHg) were found in 8.2% of patients, indicating poor therapeutic effects; 6.4% of patients had variable-staged restenosis at follow-up and 3.8% underwent reintervention by balloon dilation or surgical repairs. Further analysis demonstrated that the balloon/annulus ratio showed statistically significant differences (P < 0.05) among groups with different therapeutic effects and between the restenosis and no-stenosis groups. Binary logistic regression analysis further revealed that higher balloon/annulus ratio (odds ratio: 0.005, 95% confidence interval: 0-0.39) was an independent protective factor for restenosis. The rate of severe complications was 1.9%. CONCLUSIONS: PBPV is a definitive therapy for infants with PVS based on its effectiveness, feasibility, and safety. Restenosis upon medium-term follow-up is relatively rare. PMID- 29176138 TI - Clinical Manifestations and Amplitude-integrated Encephalogram in Neonates with Early-onset Epileptic Encephalopathy. AB - BACKGROUND: The patients with early-onset epileptic encephalopathy (EOEE) suffer from neurodevelopmental delay. The aim of this study was to analyze the clinical manifestations and amplitude-integrated encephalogram (aEEG) characteristics of infants with EOEE with onset within the neonatal period, to make early diagnosis to improve the prognosis. METHODS: One-hundred and twenty-eight patients with neonatal seizure were enrolled and followed up till 1 year old. Sixty-six neonates evolved into EOEE were as the EOEE group, the other 62 were as the non EOEE (nEOEE) group. Then we compared the clinical and aEEG characteristics between the two groups to analyze the manifestations in neonates with EOEE. RESULTS: Compared to the nEOEE group, the incidence of daily seizure attacks, more than two types of convulsions, more than two antiepileptic drugs (AEDs) application, severely abnormal aEEG background, absence of cyclicity, and more than two seizures detection were significantly higher in the EOEE group (P < 0.05) (97% vs. 54.8%; 30.3% vs. 14.5%; 97.0% vs. 25.4%; 39.4% vs. 3.2%; 57.6% vs. 9.7%; and 56% vs. 3.2%, respectively). Severely abnormal background pattern (odds ratio [OR] = 0.081, 95% confidence interval [CI]: 0.009-0.729, P = 0.025) and more than two seizures detection by aEEG (OR = 0.158, 95% CI: 0.043-0.576, P = 0.005) were the independent risk factors for the evolvement into EOEE. The upper and lower margins of active sleep (AS) and quiet sleep (QS) were significantly higher in EOEE group than those of the control group (P < 0.05) (34.3 +/- 13.6 vs. 21.3 +/- 6.4; 9.9 +/- 3.7 vs. 6.7 +/- 2.2; 41.2 +/- 15.1 vs. 30.4 +/- 11.4; and 11.9 +/- 4.4 vs. 9.4 +/- 4.0; unit: MUV, respectively). AS upper margin was demonstrated a higher diagnostic specificity and sensitivity for EOEE than another three parameters according to the receiver operating characteristic curves; the area under the curve was 0.827. CONCLUSIONS: The clinical characteristics of the neonatal seizure which will evolve into EOEE were more than two AEDs application, high seizure frequency (daily attack), and more than two types of the seizure. Significant high voltage, severely abnormal background, absence of cyclicity, and more than two seizures detected on aEEG were the meaningful indicators to the prediction of EOEE. PMID- 29176139 TI - Preoperative Evaluation and Midterm Outcomes after the Surgical Correction of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery in 50 Infants and Children. AB - BACKGROUND: Anomalous origin of the left coronary artery (LCA) from the pulmonary artery (ALCAPA) is a rather rare congenital anomaly that has a profound effect on heart function. This study aimed to retrospectively illustrate the perioperative clinical features, therapy experience, and midterm outcomes after surgical correction, and to determine the value of left ventricular ejection fraction (LVEF) and myocardial viability in differentiating critically ill patients among infants and children with ALCAPA. METHODS: From April 1999 to March 2013, infants and children patients diagnosed with ALCAPA in Beijing Fuwai Hospital were analyzed. Clinical data of patients were summarized and retrospectively analyzed. All patients were divided into two groups according to LVEF level (Group 1: LVEF >50%, or Group 2: LVEF <=50%) to compare perioperative and follow-up variables. Effect of myocardial viability evaluated according to myocardial perfusion/18F fluorodeoxyglucose (FDG) imaging on the clinical variables was also analyzed. RESULTS: A total of 50 patients with ALCAPA (male/female: 29/21; median age: 3.1 years [range: 4 months to 18 years]) were included. Younger age, lower weight, intercoronary collaterals (ICC) dysplasia, ratio of the proximal right coronary artery diameter to the aortic root diameter <0.2, and larger cardiothoracic ratio (CTR) were more frequently found in Group 2 than those in Group 1. Forty-seven patients underwent cardiac surgery. The times of cross-clamp and cardiopulmonary bypass were not different between the two groups; however, the duration of mechanical ventilation and postoperative Intensive Care Unit stay were longer in Group 2 than those in Group 1. Follow-ups were possible in 38 patients (80.9%); median time: 84.5 months (range: 49 months to 216 months). There was one late sudden death with simple ligation of the LCA at 8 months after surgery. No severe complications and reoperation occurred. The relationship of the grades of myocardial viability and clinical features was analyzed in 15 patients with myocardial perfusion/18F-FDG imaging, and the results showed that myocardial viability correlated well with LVEF, CTR, abnormal Q waves, and left ventricular end-diastolic dimension. It was not correlated with age, mitral regurgitation, and ICC. Heart implantation was decided in one patient with little viable myocardium; however, this patient died 2 months after the diagnosis while waiting for transplantation. Two patients with no viable myocardium in the area of aneurysm had aneurysmectomy concomitantly. CONCLUSIONS: In infants and children with ALCAPA, heart function and myocardial viability are closely related to clinical features. LVEF and the grades of myocardial viability can differentiate high-risk patients before surgery and in the early stage of recovery after surgery. The area and extent of myocardial infarction are also crucial in making preoperative clinical decisions. However, even in patients with depressed ventricular function and severe myocardial infarction, the midterm follow-up showed satisfactory recovery of cardiac function after the successful restoration of a dual-coronary arterial system. PMID- 29176140 TI - Role of Whole-exome Sequencing in Phenotype Classification and Clinical Treatment of Pediatric Restrictive Cardiomyopathy. AB - BACKGROUND: Restrictive cardiomyopathy (RCM) is the least common cardiomyopathy in which the walls are rigid and the heart is restricted from stretching and filling properly. Cardiac troponin I (cTnI) mutation-caused myofibril Ca2+ hypersensitivity has been shown to be associated with impaired diastolic function. This study aimed to investigate the linkage between the genotype and clinical therapy of RCM. METHODS: Five sporadic pediatric RCM patients confirmed by echocardiography were enrolled in this study. Whole-exome sequencing (WES) was performed for the cohort to find out candidate causative gene variants. Sanger sequencing confirmed the WES-identified variants. RESULTS: TNNI3 variants were found in all of the five patients. R192H mutation was shared in four patients while R204H mutation was found only in one patient. Structure investigation showed that the C terminus of TNNI3 was flexible and mutation on the C terminus was possible to cause the RCM. Catechins were prescribed for the five patients once genotype was confirmed. Ventricular diastolic function was improved in three patients during the follow-up. CONCLUSIONS: Our data demonstrated that TNNI3 mutation-induced RCM1 is the most common type of pediatric RCM in this study. In addition, WES is a reliable approach to identify likely pathogenic genes of RCM and might be useful for the guidance of clinical treatment scheme. PMID- 29176141 TI - Safflower Extract and Aceglutamide Injection Promoting Recovery of Peripheral Innervations via Vascular Endothelial Growth Factor-B Signaling in Diabetic Mice. AB - BACKGROUND: Safflower extract and aceglutamide (SA) has been used clinically for the treatment of cerebrovascular diseases such as cerebral embolism, hemorrhage, and mental deterioration. This study aimed to investigate the effect and mechanism of SA injection in the recovery of peripheral innervations of diabetic mice. METHODS: The C57BL/6 male mice were divided into four groups: normal control group (n = 44), diabetic group (n = 44), diabetic + SA group (diabetic mice treated with SA injection, n = 44), and diabetic + SA + vascular endothelial growth factor receptor (VEGFR)1-BL group (diabetic mice treated with SA injection and VEGFR 1 blocking antibody n = 24). The streptozotocin-induced diabetic mice model and injured peripheral nerve mice model were built. The mice with injured peripheral nerves were intraperitonealy administered with SA injection for successive 21 days. The corneal sensitivity, number of corneal nerve fibers, and contents of vascular endothelial growth factor (VEGF)-B and various neurotrophic factors such as nerve growth factor (NGF) and glial cell line-derived neurotrophic factor (GDNF) in corneal tissue of four groups were observed. RESULTS: The diabetic group showed decreased number of corneal nerve fibers, compared with the control group (P = 0.002). And compared with the diabetic group, the diabetic + SA group showed a significant increase in the number of nerve fibers (P = 0.024) and the contents of VEGF-B, NGF, and GDNF in the cornea (all P < 0.05). However, when the diabetic mice were treated with the blocking antibodies specialized for VEGF-B receptor, the neutralization of VEGFR-1 completely abolished the increased expression of NGF and GDNF stimulated by SA injection. CONCLUSIONS: SA injection could reduce the nerve injury caused by diabetic peripheral neuropathy, and its protective effect might be associated with the promotion of the expressions of VEGF-B, NGF, and GDNF. PMID- 29176142 TI - Efficiency and Productivity of County-level Public Hospitals Based on the Data Envelopment Analysis Model and Malmquist Index in Anhui, China. AB - BACKGROUND: China began to implement the national medical and health system and public hospital reforms in 2009 and 2012, respectively. Anhui Province is one of the four pilot provinces, and the medical reform measures received wide attention nationwide. The effectiveness of the above reform needs to get attention. This study aimed to master the efficiency and productivity of county-level public hospitals based on the data envelopment analysis (DEA) model and Malmquist index in Anhui, China, and then provide improvement measures for the future hospital development. METHODS: We chose 12 country-level hospitals based on geographical distribution and the economic development level in Anhui Province. Relevant data that were collected in the field and then sorted were provided by the administrative departments of the hospitals. DEA models were used to calculate the dynamic efficiency and Malmquist index factors for the 12 institutions. RESULTS: During 2010-2015, the overall average relative service efficiency of 12 county-level public hospitals was 0.926, and the number of hospitals achieved an effective DEA for each year from 2010 to 2015 was 4, 6, 7, 7, 6, and 8, respectively, as measured using DEA. During this same period, the average overall production efficiency was 0.983, and the total productivity factor had declined. The overall production efficiency of five hospitals was >1, and the rest are <1 between 2010 and 2015. CONCLUSIONS: In 2010-2015, the relative service efficiency of 12 county-level public hospitals in Anhui Province showed a decreasing trend, and the service efficiency of each hospital changed. In the past 6 years, although some hospitals have been effective, the efficiency of the county-level public hospitals in Anhui Province has not improved significantly, and the total factor productivity has not been effectively improved. County-level public hospitals need to combine their own reality to find their own deficiencies. PMID- 29176143 TI - Effect of Cognitive Behavioral Therapy Versus Interpersonal Psychotherapy in Patients with Major Depressive Disorder: A Meta-analysis of Randomized Controlled Trials. AB - BACKGROUND: Practice guidelines have recommended cognitive behavioral therapy (CBT) and interpersonal psychotherapy (IPT) as the treatment of choice for major depression disorder (MDD). However, whether one therapy is better than the other remains inconclusive. The aim of this study was to compare the treatment efficacy of the two treatment approaches for MDD. METHODS: Using the terms "cognitive behavior therapy or cognitive therapy or CBT or CT or cognitive behavioral therapy" and "interpersonal psychotherapy or IPT," we systematically searched PubMed, Psyclnfo and Chinese National Knowledge Infrastructure databases up to February 2017. The language was restricted to be English and Chinese. Therapeutic outcomes, characteristics, and research quality were then extracted and analyzed independently. In accessing the included studies, we followed the criteria suggested by the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: Data for 946 patients from 10 randomized controlled trials were included in the study. Methodological quality was not optimal in most trials. Meta analysis showed a mean difference (MD) of -1.31, 95% confidence interval (CI) ( 2.49, -0.12) (P < 0.05) in favor of CBT according to the Beck Depression Inventory (BDI), and however, we did not found any statistically significant difference between CBT and IPT on the Hamilton Rating Scale for depression (HRSD) (MD -0.90, 95% CI [-2.18, 0.38]). Subgroup analyses for the studies in which patients were treated only by psychotherapy (MD -1.26, 95% CI [-2.78, 0.35]) and for those which offered more sessions of therapies (MD -0.82, 95% CI [-2.23, 0.59]) showed there was no significant difference between CBT and IPT according to BDI. CONCLUSIONS: Differences in treatment efficacy seem to vary according to different outcome measures. CBT shows an advantage over IPT for MDD according to BDI, and there is no significant difference between the two according to HRSD. These results should be interpreted with caution.

PMID- 29176145 TI - Autoimmune-associated Congenital Heart Block: A New Insight in Fetal Life. AB - OBJECTIVE: Congenital heart block (CHB) is a rare but life-threatening disorder. More than half of CHB cases are associated with maternal autoimmune, which are termed as autoimmune-associated CHB. This review summarized the recent research findings in understanding autoimmune-associated CHB, discussed the current diagnostic approaches and management strategies, and summarized the problems and future directions for this disorder. DATA SOURCES: We retrieved the articles published in English from the PubMed database up to January 2017, using the keywords including "Autoimmune-associated", "Autoimmune-mediated", and "Congenital heart block". STUDY SELECTION: Articles about autoimmune-associated CHB were obtained and reviewed. RESULTS: Observational studies consistently reported that transplacental maternal antibodies might recognize fetal or neonatal antigens in various tissues and result in immunological damages, but the molecular mechanisms underlying CHB pathogenesis still need illuminated. Multiple factors were involved in the process of atrioventricular block development and progression. While several susceptibility genes had been successfully defined, how these genes and their protein interact and impact each other remains to be explored. With currently available diagnostic tools, fetal ultrasound cardiography, and fetal magnetocardiography, most of CHB could be successfully diagnosed and comprehensively evaluated prenatally. The efficacy of current approaches for preventing the progression and recurrence of CHB and other autoimmune-mediated damages was still controversial. CONCLUSIONS: This review highlighted the relationships between autoimmune injuries and CHB and strengthened the importance of perinatal management and therapy for autoimmune associated CHB.

AB - Acute lung injury (ALI) is one of the complications of severe sepsis, causing sudden deaths. However, information regarding predictive factors for the onset of ALI in severe sepsis is limited. Growth arrest-specific gene 6 (Gas6) is secreted by endothelial cells and is important for the activation of endothelium during inflammation. This study aimed to investigate the predictive effect of plasma Gas6 in patients with severe sepsis. Collection of plasma samples was carried out from 129 participants with severe sepsis following with or without ALI development. We found that the elevated levels of Gas6, interleukin-6 and -8 (IL 6 and IL-8) in plasma were associated with the ALI development (P = 0.003, 0.002, and 0.004, respectively). We also observed the robust correlation between the plasma level of Gas6 and the following ALI development to adjustment for sepsis and administration of vasopressor. Between patients with ALI (n = 18) and those without ALI (n = 111), Gas6 and the Lung Injury Prediction Score (LIPS) showed promising discrimination (AUROC, 0.74 and 0.68, respectively), and in combination with these two indexes, the AUROC was increased to 0.86 (vs. 0.74, P = 0.05), while soluble receptor for advanced glycation end products (sRAGE) and Willebrand factor (vWF) in plasma showed no predictive value for of ALI. Collectively, our findings indicate that higher levels of Gas6 in plasma are obviously correlated with ALI development. An early increase in the plasma Gas6 level suggests that endothelial injury is a key link in the pathogenesis of ALI. PMID- 29176261 TI - Reduced Vitamin D Receptor on Circulating Endothelial Progenitor Cells: A New Risk Factor of Coronary Artery Diseases. AB - AIM: Endothelial progenitor cells (EPCs) are shown to participate in the pathological processes of atherosclerosis. While Vitamin D and its receptor axis might exert some effects on EPCs' function. But their exact relationship with clinical patients is still elusive, which inspired us to explore the potential association of vitamin D receptor (VDR) expression on circulating EPCs and serum vitamin D levels among patients with coronary artery disease (CAD). METHODS: Two hundred patients with CAD after their admission to hospital and one hundred healthy controls were enrolled. Medical history data were retrieved and fresh blood samples were collected for flow cytometry analysis. VDR expressions on EPCs were evaluated according to the standardized protocol. Logistic regression analysis was used to investigate the potential risk factor of CAD. RESULTS: CAD patients were found to have lower log10VDR-MFIs than those of control group, especially for patients with diabetes (p<0.001). Log10VDR-MFIs were inversely correlated with glycated hemoglobin (R=-0.472, p<0.001), and while EPCs challenged with high glucose had lower VDR expression. Multivariate logistic regression analysis revealed that lower log10VDR-MFIs were independently associated with the risk of CAD (OR=0.055, p=0.008). CONCLUSION: A significant decrease of VDR expression on circulating EPCs was observed among CAD patients, particularly among those also with diabetes. VDR expression on EPCs was independently negatively correlated with HbA1c and high glucose decreased EPCs' VDR expression. Low levels of VDR expression on circulating EPCs might serve as a potential risk factor of CAD. PMID- 29176263 TI - A study on periostin involvement in the pathophysiology of canine atopic skin. AB - Atopic dermatitis (AD) is a chronic, pruritic, and allergic skin disease in humans and animals, particularly dogs. Canine AD (cAD) has received attention as a spontaneous atopic animal model because domesticated dogs inhabit a human environment, and cAD shares several clinicopathological features with human AD (hAD). In hAD, periostin (PO) is suggested to play a critical role in the enhancement and chronicity of allergic skin inflammation; however, PO involvement in the pathogenesis of cAD is unknown. Here we aimed to clarify PO involvement in the pathophysiology of cAD and focused on the inducing factor and function of PO in canine atopic skin. Using double-labeled in situ hybridization (ISH), interleukin (IL)-13 mRNA-positive cells were detected near the keratinocytes and dermal fibroblasts expressing PO mRNA in atopic skin. Using an in vitro assay, IL 13 induced PO gene expression in both canine dermal fibroblasts and keratinocytes. PO enhanced in vitro growth of canine keratinocytes. Moreover, among PO-induced genes in cultured canine keratinocytes detected using a microarray, we identified IL-25 as a possible mediator in canine atopic skin. In addition, real time polymerase chain reaction (PCR) analysis revealed upregulation of IL-25 gene expression in PO-stimulated keratinocytes. These data suggest that IL-13 possibly derived from T helper 2 (Th2) cells stimulates PO production in both keratinocytes and fibroblasts, and then PO may play a critical role in the pathophysiology of cAD, particularly in the enhancement and chronicity of skin lesions via IL-25. PMID- 29176264 TI - Efficacy of Chondroitin Sulfate for Painful Knee Osteoarthritis: A One-Year, Randomized, Double-Blind, Multicenter Clinical Study in Japan. AB - We explored the effects of chondroitin sulfate on knee osteoarthritis in a one year, randomized, double-blind, dose-comparison study. Patients with painful, Kellgren-Lawrence grade 2-3, osteoarthritis of the knee were treated with oral chondroitin sulfate at a dose of either 260 mg/d (low-dose group, control group) or 1560 mg/d (high-dose group). Symptoms were evaluated by the Lequesne's index and visual analog scale for pain. We made subgroup analyses according to background symptom severity (Lequesne's index >=8 or <8) in 73 patients. Serum level of cartilage oligomeric matrix protein and hyaluronic acid were also determined. In the subgroup with severe symptoms (Lequesne's index >=8), the chondroitin sulfate dose of 1560 mg/d improved pain faster after 6 and 9 months' therapy. However, no dose-related effects were found on cartilage oligomeric matrix protein or hyaluronic acid levels. Chondroitin sulfate also had good tolerability. We conclude that chondroitin sulfate is useful for pain control in knee osteoarthritis. PMID- 29176265 TI - The Effect of Ethanol on the Hydrolysis of Ester-Type Drugs by Human Serum Albumin. AB - Human serum albumin (HSA) has two major ligand-binding sites, sites I and II, and hydrolyzes compounds at both sites. Although the hydrolytic interaction of ester type drugs with other drugs by HSA has been reported, there are only a few studies concerning the effect of pharmaceutical excipients on the hydrolysis of ester-type drugs by HSA. In the present study, we investigated the effect of ethanol (2 vol%; 345 mM) on the hydrolysis of aspirin, p-nitrophenyl acetate, and olmesartan medoxomil, which are ester-type drugs, with 4 different lots of HSA preparations. The hydrolysis activities of HSA toward aspirin, p-nitrophenyl acetate, and olmesartan medoxomil were measured from the pseudo-first-order degradation rate constant (kobs) of salicylic acid, p-nitrophenol, and olmesartan, respectively, which are the HSA-hydrolyzed products. Ethanol inhibited hydrolysis of aspirin by HSA containing low levels of fatty acids, but not by fatty acid-free HSA. Ethanol inhibited hydrolysis of p-nitrophenyl acetate by both fatty acid-free HSA and HSA containing low levels of fatty acids. In contrast, the hydrolysis of olmesartan medoxomil by HSA was insignificantly inhibited by ethanol, but inhibited not only by warfarin and indomethacin but also by naproxen, which are site I binding drugs and a site II binding drug, respectively. These results suggest that the inhibitory action of ethanol on the hydrolysis of ester-type drugs by HSA differs between site I binding drugs and site II binding drugs. PMID- 29176266 TI - Fibrin Clot Architecture in Acute Ischemic Stroke Treated With Mechanical Thrombectomy With Stent-Retrievers - Cohort Study. AB - BACKGROUND: The composition of intra-arterial clots might influence the efficacy of mechanical thrombectomy (MT) in ischemic stroke (IS) due to the acute occlusions within large cerebral arteries. The aims were to assess the factors associated with blood clot structure and the impact of thromboembolus structure on MT using stent-retrievers in patients with acute large artery IS in the anterior circulation.Methods and Results:In an observational cohort study, we studied the components of intra-arterial clots retrieved from large cerebral arteries in 80 patients with acute IS treated with MT with or without i.v. thrombolysis (IVT). Histology of the clots was carried out without knowledge of the clinical findings, including the treatment methods. The components of the clots, their age, origin and semi-quantitative graded changes in the architecture of the fibrin components (e.g., "thinning") were compared via neuro interventional, clinical and laboratory data. The most prominent changes in the architecture of the fibrin components in the thromboemboli were associated with IVT (applied in 44 patients; OR, 3.50; 95% CI: 1.21-10.10, P=0.02) and platelet count (OR, 2.94; 95% CI: 1.06-8.12, P=0.04). CONCLUSIONS: In patients with large artery IS treated with the MT using stent-retrievers, bridging therapy with IVT preceding MT and higher platelet count were associated with significant changes of the histological structure of blood clots. PMID- 29176267 TI - Examination of validity of a conditioned odor aversion (COA) procedure using low dose of organic solvent as an applied procedure of the conditioned taste aversion. AB - Smell of very low dose of chemical might evoke subjective physical symptoms in human by some process of learning named the aversion conditioning. But few scientific evidences of the hypothesis have been reported so far. Validity of conditioned odor aversion (COA) using low-doses of organic solvent as odor conditioned stimulus (CS) was examined. In conditioning phase, water-deprived male Sprague-Dawley rats were presented low, medium or high dose solution for 30 min followed by 0.3 M Lithium Chloride (LiCl) solution or saline injection. The xylene solution and drink water were simultaneously provided on the next day as two-bottle test. Consumption of medium dose of xylene solution was significantly decreased in LiCl injection group as compared with saline group. There was no difference between LiCl and saline injected animals in low group. Animals in high dose did not access to xylene even on the conditioning. These results indicate that animals showed high sensitivity for discrimination against concentration of xylene and that the medium dose of xylene functioned as the CS. We concluded that the COA used in the present study may be one of useful procedures to investigate olfaction of animal. PMID- 29176268 TI - Hemodynamic Implications of Carbon Monoxide (CO) and Nitrogen Oxide (NO) during Living Donor Liver Transplantation. AB - Carbon monoxide (CO) and nitrogen oxide (NO) affect vasodilation and cause hemodynamic change. Hemodynamic instability due to liver transplantation may result in poor prognosis of graft. This study investigated the hemodynamic implications of CO and NO levels measured using carboxyhemoglobin (COHb) and methemoglobin (MetHb) during living donor liver transplantation (LDLT). The hemodynamic instability with a pressor dose (norepinephrine equivalent) was estimated 1 hour after graft reperfusion. COHb and MetHb were used as indexes of CO and NO, and were measured using an arterial blood gas analyzer. One hundred and ten recipients who underwent LDLT from May 2011 to July 2013 were selected. Recipients were divided into high (>= 1.9%) and low (< 1.9%) COHb groups with COHb concentrations at 5 minutes after reperfusion. Recipients were also divided into high (>= 0.4%) and low (< 0.4%) MetHb groups with MetHb concentrations at 30 minutes after reperfusion. Data are presented as mean +/- standard deviation or number (percentage). Model for End-stage Liver Disease (MELD) scores were different for the two COHb groups (low: 13.4 +/- 9.0 vs. high: 19.7 +/- 10.6, p < 0.001), and pressor doses adjusted by MELD scores were also different between the two COHb groups (low: 0.09 +/- 0.01 MUg/kg/min vs. high: 0.14 +/- 0.01 MUg/kg/min, p = 0.029). By contrast, pressor doses and MELD scores were not different between the two MetHb groups. In conclusion, CO rather than NO has hemodynamic implications during LDLT. Therefore, the increase in COHb during LDLT is predictive of hemodynamic instability. PMID- 29176270 TI - An Unusual Foreign Body in the Heart: A Case Report. AB - Penetrating foreign bodies in the heart is rare and may lead to life-threatening complications. Early diagnosis and removal are crucial for these rare cases. We report a case of accidental penetrating sewing needle in the right ventricle. The needle was successfully removed without open heart surgery and cardiopulmonary bypass (CPB), after accurate localization using transthoracic echocardiography (TTE). PMID- 29176269 TI - Clinical and Radiological Outcomes of Microscopic Lumbar Foraminal Decompression: A Pilot Analysis of Possible Risk Factors for Restenosis. AB - A single-center retrospective comparative study was designed to identify the risk factors for restenosis of lumbar foraminal stenosis (LFS) after microscopic foraminal decompression (MFD). 21 consecutive patients who underwent single-level MFD with an average of 19-month follow-up were divided into two study groups based on clinical outcomes; group 1 (7 patients with poor outcomes requiring revision surgery), group 2 (14 patients with good outcomes with no revision surgery required). Changes of lumbar spinal alignment on plain standing radiographs were compared and analyzed between two study groups to investigate the pathology and risk factors associated with restenosis after MFD. Preoperative disc wedging (DW) angle was significantly larger in group 1 than in group 2 (3.5 +/- 1.0 degrees vs 1.1 +/- 0.2 degrees , P < 0.01). Postoperatively, disc height (DH) and foraminal height (FH) decreased (P < 0.05), and DW deteriorated (P < 0.01) significantly in group 1, while there were no significant changes in group 2. Lumbar lordosis (LL) remarkably improved postoperatively in group 2 (24.7 +/- 8.0 to 32.0 +/- 7.0, P < 0.001), contrary to limited improvement in group 1 (25.1 +/- 9.2 to 27.0 +/- 12.0, P = 0.45). Postoperative LL is a predictive factor for restenosis after MFD. Decrease in DH or progression of DW was contributing to restenosis. LFS presenting with large DW and lumbar degenerative kyphosis should be excluded from surgical indications for MFD without instrumented fusion, considering the high recurrence rate. PMID- 29176271 TI - Patterns of Ultraviolet Radiation Exposure and Skin Cancer Risk: the E3N-SunExp Study. AB - BACKGROUND: While ultraviolet (UV) radiation exposure is a recognized risk factor for skin cancer, associations are complex and few studies have allowed a direct comparison of exposure profiles associated with cutaneous melanoma, basal-cell carcinoma (BCC), and squamous-cell carcinoma (SCC) within a single population. METHODS: We examined associations between UV exposures and skin cancer risk in a nested case-control study within E3N, a prospective cohort of 98,995 French women born in 1925-1950. In 2008, a lifetime UV exposure questionnaire was sent to all reported skin cancer cases and three controls per case, which were matched on age, county of birth, and education. Analyses were performed using conditional logistic regression and included 366 melanoma cases, 1,027 BCC cases, 165 SCC cases, and 3,647 controls. RESULTS: A history of severe sunburns <25 years was associated with increased risks of all skin cancers (melanoma: OR 2.7; BCC: OR 1.7; SCC: OR 2.0 for >=6 sunburns vs. none), while sunburns >=25 years were associated with BCC and SCC only. While high-sun protection factor sunscreen use before age 25 was associated with lower BCC risk (Ptrend = 0.02), use since age 25 and reapplication of sunscreen were associated with higher risks of all three types of skin cancer. There were positive linear associations between total UV score and risks of BCC (Ptrend = 0.01) and SCC (Ptrend = 0.09), but not melanoma. While recreational UV score was strongly associated with BCC, total and residential UV scores were more strongly associated with SCC. CONCLUSIONS: Melanoma, BCC, and SCC are associated with different sun exposure profiles in women. PMID- 29176273 TI - Importance of Achieving a "Fit" Cardiorespiratory Fitness Level for Several Years on the Incidence of Type 2 Diabetes Mellitus: A Japanese Cohort Study. AB - BACKGROUND: The "Physical Activity Reference for Health Promotion 2013" provides "fit" reference values for cardiorespiratory fitness (CRF) for good health. The importance of achieving a fit CRF level for several years on the subsequent prevention of type 2 diabetes mellitus (T2DM) remains to be clarified. METHODS: This cohort study was conducted in 2,235 nondiabetic males aged 21 to 59 years, enrolled in April 1986 through March 1987. We calculated the ratio of the area under the curve (AUCratio) for actual measured values and the AUC for the reference values of CRF in each individual during an 8-year measurement period before the baseline. According to whether they met a fit CRF level or not, participants were categorized into groups based on the AUCratio (FitAUC or UnfitAUC) and initial CRF (Fitinitial or Unfitinitial), respectively. T2DM was evaluated on health checkups until March 2010. RESULTS: During the follow-up period, 400 men developed T2DM. After adjustment for confounders, as compared with those in the FitAUC group, the hazard ratio (HR) for those in the UnfitAUC group was 1.33 (95% confidence interval [CI], 1.06-1.65). A combined analysis with the categories of initial value and AUCratio showed that, compared with the Fitinitial and FitAUC group, the HRs of Fitinitial and UnfitAUC, Unfitinitial and FitAUC, and Unfitinitial and UnfitAUC groups were 1.41 (95% CI, 0.99-2.00), 1.18 (95% CI, 0.81-1.70), and 1.40 (95% CI, 1.08-1.83), respectively. CONCLUSION: Achievement of a fit CRF level established in the Japan physical activity guideline for several years was associated with lower subsequent risk of T2DM. PMID- 29176272 TI - Modification of the Associations of Alcohol Intake With Serum Low-Density Lipoprotein Cholesterol and Triglycerides by ALDH2 and ADH1B Polymorphisms in Japanese Men. AB - BACKGROUND: Although beneficial associations have been reported between moderate alcohol intake and the serum lipid profile, it is unclear whether polymorphisms in alcohol-metabolizing enzymes can modify these associations. Here, we assessed the effects of ADH1B His48Arg (rs1229984), ALDH2 Glu504Lys (rs671), and their combination on these associations. Furthermore, we examined if the findings for ALDH2 could be replicated. METHODS: We categorized 889 male participants in the Japan Multi-Institutional Collaborative Cohort (J-MICC) Study into two groups based on presence or absence of minor allele(s) or four groups based on genotype combinations. We performed regression analyses of serum lipid concentrations on alcohol intake, with multivariable adjustment. The replication study was conducted among 2,562 men in the Shizuoka part of the J-MICC Study. RESULTS: The ALDH2 Glu/Lys or Lys/Lys groups showed significant decreases in serum low-density lipoprotein (LDL) cholesterol with increasing alcohol consumption; the coefficient per intake increase of 10 g/day was -2.49 mg/dL (95% confidence interval [CI], -3.85 to -1.13), and a significant interaction with the polymorphism was confirmed (P for interaction = 0.006). This inverse correlation was more evident among the ADH1B His/His + ALDH2 Glu/Lys or Lys/Lys groups (-3.24 mg/dL, 95% CI, -5.03 to -1.45). Serum triglycerides were positively associated with alcohol consumption in the ADH1B His/His group (P for interaction = 0.020). The stronger association between serum LDL cholesterol and alcohol consumption in the ALDH2 Glu/Lys or Lys/Lys groups was replicated. CONCLUSIONS: The ALDH2 Glu504Lys polymorphism can modify the association between alcohol intake and serum LDL cholesterol in Japanese men. PMID- 29176276 TI - ? PMID- 29176274 TI - Increased Incidence of Visual Field Abnormalities as Determined by Frequency Doubling Technology Perimetry in High Computer Users Among Japanese Workers: A Retrospective Cohort Study. AB - BACKGROUND: This retrospective cohort study primarily aimed to investigate the possible association of computer use with visual field abnormalities (VFA) among Japanese workers. METHODS: The study included 2,377 workers (mean age 45.7 [standard deviation, 8.3] years; 2,229 men and 148 women) who initially exhibited no VFA during frequency doubling technology perimetry (FDT) testing. Subjects then underwent annual follow-up FDT testing for 7 years, and VFA were determined using a FDT-test protocol (FDT-VFA). Subjects with FDT-VFA were examined by ophthalmologists. Baseline data about the mean duration of computer use during a 5-year period and refractive errors were obtained via self-administered questionnaire and evaluations for refractive errors (use of eyeglasses or contact lenses), respectively. RESULTS: A Cox proportional hazard analysis demonstrated that heavy computer users (>8 hr/day) had a significantly increased risk of FDT VFA (hazard ratio [HR] 2.85; 95% confidence interval [CI], 1.26-6.48) relative to light users (<4 hr/day), and this association was strengthened among subjects with refractive errors (HR 4.48; 95% CI, 1.87-10.74). The computer usage history also significantly correlated with FDT-VFA among subject with refractive errors (P < 0.05), and 73.1% of subjects with FDT-VFA and refractive errors were diagnosed with glaucoma or ocular hypertension. CONCLUSIONS: The incidence of FDT VFA appears to be increased among Japanese workers who are heavy computer users, particularly if they have refractive errors. Further investigations of epidemiology and causality are warranted. PMID- 29176275 TI - Patterns and Levels of Sedentary Behavior and Physical Activity in a General Japanese Population: The Hisayama Study. AB - BACKGROUND: The purpose of this cross-sectional study was to describe the patterns and levels of sedentary time and physical activity (PA) in a general Japanese population. METHODS: A total of 1,740 community-dwelling Japanese adults aged >=40 years participated in this study. Sedentary time and PA were assessed for 7 consecutive days using a tri-axial accelerometer. Daily patterns and levels of sedentary time and PA were calculated by sex, age group (40-64, 65-74, and >=75 years), and body mass index (BMI; <25 and >=25 kg/m2). RESULTS: Participants spent half of their waking time being sedentary, 32.7% of which was accumulated in prolonged bouts >=30 minutes, versus only 54.4 minutes/day (7% of waking time) as moderate-to-vigorous PA (MVPA) (11.8 minutes/day in bouts >=10 minutes). In addition to total sedentary time, men had longer prolonged sedentary bouts and fewer breaks per sedentary hour than women. Similar trends were observed in participants aged >=75 years and those with a higher BMI (>=25 kg/m2) compared to those with a younger age and lower BMI. Moreover, participants aged >=75 years and those with a higher BMI accumulated fewer MVPA minutes in bouts >=10 minutes. Only 34.8% of the population met the recommended level of >=150 minutes/week MVPA in bouts >=10 minutes. CONCLUSION: Japanese adults accumulated a large proportion of total sedentary time in prolonged bouts but few minutes in sustained bouts of MVPA, and few of them met the current PA guideline.

AB - Periostin is an extracellular matrix N-glycoprotein that is a major constituent of the desmoplastic stroma around solid tumors. Periostin promotes tumor invasion and metastasis via epithelial-mesenchymal transition. The aims of this study were to evaluate periostin expression immunohistochemically and quantitatively in patients with non-small cell lung cancer (NSCLC) and to assess any associations with clinical features and prognosis. A total of 184 specimens of NSCLC tissue were investigated, including 134 adenocarcinomas, 39 squamous cell carcinomas, and 11 other histologic subtypes. The intra-tumoral periostin expression area in each captured field was calculated using the image processing integration software WinROOF. The mean periostin expression score was classified as high or low by the median value of its expression area. Univariate analysis demonstrated that gender, tumor size, T status, N status, stage, histologic type, smoking habits, percent vital capacity, 1% forced expiratory volume, and pleural invasion were each significantly associated with periostin scores. Multivariate analysis revealed that high periostin expression score was an independent prognostic factor significantly associated with decreased cancer-specific survival (HR, 3.65; 95% CI, 1.04-12.84; P=0.0439). We concluded that intratumoral periostin expression was an independent prognostic factor for NSCLC. PMID- 29176297 TI - Treatment of a Large Pharyngeal Venous Malformation using Transoral Sclerotherapy. AB - Management of venous malformation (VM) in the pharynx is challenging because of difficulties in needle access and the presence of nerves as well as other critical anatomical structures around the lesion. We describe the successful treatment of a large pharyngeal VM using transoral sclerotherapy. The patient, a 21-yearold male, visited our hospital for sclerotherapy treatment consultation after complaining of difficulty in swallowing because of a pharyngeal VM. Transoral sclerotherapy was successful, and the symptoms showed complete alleviation. Using a flat detector-equipped angiographic C-arm CT (CACT) enabled the precise assessment of sclerosant placement, facilitating safer sclerotherapy in the pharynx. PMID- 29176298 TI - Smaller effect of propofol than sevoflurane anesthesia on dopamine turnover induced by methamphetamine and nomifensine in the rat striatum: an in vivo microdialysis study. AB - Volatile anesthetics accelerate dopamine turnover in the brain, especially when used in conjunction with psychotropic agents such as methamphetamine and nomifensine. The effect of intravenous propofol anesthesia on the extracellular dopamine concentrations is unclear. The aim of this study was to compare the effect of two anesthetics on the extracellular concentrations of dopamine and metabolites using an in vivo microdialysis model. Male Sprague Dawley rats were implanted with a microdialysis probe into the right striatum. The probe was perfused with modified Ringer's solution, and the dialysate was directly injected into a high-performance liquid chromatography system every 20 min. The rats were intraperitoneally administered saline, methamphetamine at 2 mg/kg, or nomifensine at 10 mg/kg. After treatment, the rats were anesthetized with intravenous propofol (20 mg/kg followed by 25 or 50 mg/kg/h) or inhalational sevoflurane (2.5%) for 1 h. Propofol showed no effect on the extracellular concentration of dopamine during anesthesia; however, propofol decreased the dopamine concentration after anesthesia in the high-dose group. Sevoflurane anesthesia increased the concentration of metabolites. Systemic administration of methamphetamine and nomifensine increased the extracellular concentration of dopamine. Sevoflurane anesthesia significantly enhanced the increase in the dopamine concentration induced by both methamphetamine and nomifensine, whereas propofol anesthesia showed no effect on the methamphetamine- and nomifensine induced dopamine increase during anesthesia. The enhancing effect of psychotropic agent-induced acceleration of dopamine turnover was smaller for propofol anesthesia than for sevoflurane anesthesia. PMID- 29176299 TI - Effects of calcium-containing desensitizers on the bonding stability of an etch and-rinse adhesive against long-term water storage and pH cycling. AB - This study aimed to evaluate the effects of two calcium-containing desensitizing pastes on the bonding stability of an etch-and-rinse (E&R) adhesive to dentine. After dentine hypersensitivity model established, dentine surfaces were assigned one of the following pretreatment: Group 1, no desensitizer; Group 2, CPP-ACP; and Group 3, Novamin. Specimens were then bonded with an E&R adhesive. Beams from each tooth were randomly divided into three subgroups and then subjected to microtensile bond strength (MTBS) test after 24 h; 12 months of water storage; or 15 runs of pH cycling. Failure modes, nanoleakage, and tubule-occluding effectiveness were analyzed. Results showed that CPP-ACP- or Novamin-pretreated specimens mainly preserved the bonding strength after 12 months of water storage, while effective tubule occlusion could be observed. The results suggested that the calcium-containing desensitizers were compatible pretreatment for bonding with E&R adhesives to obtain reliable long-term bonding strength and prevention of post-operative sensitivity. PMID- 29176300 TI - Effect of doxycycline-treated hydroxyapatite surface on bone apposition: A histomophometric study in murine maxillae. AB - Improved osseointegration of dental implants is imperative in clinic. Effect of doxycycline on promoting bone formation after implant placement was expected due to its inhibitory properties on inflammation and osteoclastogenesis. To evaluate new bone formation on the hydroxyapatite (HA)-coated implant surface, which was treated with doxycycline, in comparison with the untreated HA surface, half of the HA-coated implants were soaked in doxycycline solution (DOX group) whereas the other HA-coated implants were untreated (HA group). Eight weeks after extracting the maxillary first molars of 4-week-old male mice, the implants of both groups were placed at the extracted site. 4 and 8 weeks after surgery, the samples were evaluated radiologically and histomorphometrically. Bone-implant contact of DOX group was statistically higher than the one of HA group at 4 and 8 weeks. New bone area between the threads of the implants also statistically increased at 8 weeks in DOX group compared to HA group. PMID- 29176301 TI - A novel cold atmospheric pressure air plasma jet for peri-implantitis treatment: An in vitro study. AB - Peri-implantitis is difficult to treat in clinical settings; this is not only because it is a site-specific infectious disease but also because it impedes osseointegration. In this study, a novel cold atmospheric pressure air plasma jet (CAPAJ) was applied to study the treatment of peri-implantitis in vitro. CAPAJ treated the samples for 2, 4 and 6 min, respectively. To evaluate the titanium surface characteristics, the surface elemental composition (X-ray photoelectron spectroscopy [XPS]), roughness and hydrophilicity were evaluated in each group. Concurrently, the sterilization and osseointegration effect of CAPAJ were also examined. Results revealed that after CAPAJ modification, roughness and hydrophilicity of titanium surfaces were significantly increased. Moreover, XPS results demonstrated that the C1s peak was reduced and N1s and O1s peaks were obviously improved. More importantly, CAPAJ showed favorable sterilization and bone formation effects. CAPAJ seemed a simpler and more efficient strategy for the peri-implantitis treatment. PMID- 29176302 TI - Influence of increment thickness on radiant energy and microhardness of bulk-fill resin composites. AB - Determining the energy transferred at the bottom of eleven bulk-fill resin composites, comparing top and bottom microhardness's and evaluating the correlation between microhardness and radiant energy were aimed. Samples were placed over the bottom sensor of a visible light transmission spectrophotometer and polymerized for 20 s. The bottom and top Knoop microhardness were measured. Paired t-test and correlation analysis were used for statistics (p<=0.05). In all groups, the bottom radiant energy decreased significantly with increasing thickness. For groups of Aura 2 mm, X-tra Fil 2 and 4 mm, SDR 2 and 4 mm, X-tra Base 2 mm no significant difference was found between top and bottom microhardness. For the bottom levels of Aura, X-tra Fil, Filtek Bulk-Fill Posterior, SDR, X-tra Base groups no significant difference was found between the microhardness's of 2 and 4 mm thicknesses. For X-tra Fil, Tetric Evo Ceram Bulk Fill, Filtek Bulk-Fill Flowable and Z100 groups radiant energy affected positively the microhardness. PMID- 29176303 TI - Comparison of enamel bond fatigue durability between universal adhesives and two step self-etch adhesives: Effect of phosphoric acid pre-etching. AB - The effect of phosphoric acid pre-etching on enamel bond fatigue durability of universal adhesives and two-step self-etch adhesives was investigated. Four universal adhesives and three two-step self-etch adhesives were used. The initial shear bond strengths and shear fatigue strengths to enamel with and without phosphoric acid pre-etching using the adhesives were determined. SEM observations were also conducted. Phosphoric acid pre-etching of enamel was found to increase the bond fatigue durability of universal adhesives, but its effect on two-step self-etch adhesives was material-dependent. In addition, some universal adhesives with phosphoric acid pre-etching showed similar bond fatigue durability to the two-step self-etch adhesives, although the bond fatigue durability of universal adhesives in self-etch mode was lower than that of the two-step self-etch adhesives. Phosphoric acid pre-etching enhances enamel bond fatigue durability of universal adhesives, but the effect of phosphoric acid pre-etching on the bond fatigue durability of two-step self-etch adhesives was material-dependent. PMID- 29176304 TI - Dual function of proanthocyanidins as both MMP inhibitor and crosslinker in dentin biomodification: A literature review. AB - Proanthocyanidin, a natural phytochemical bioactive agent, simultaneously can silence the activity of dentinal proteases and crosslink the collagen matrix; both of these phenomena would be the fundamentals for bio-stability of resin dentin interface which is essential for a promising adhesive dentistry. This review provides an overview of the data developed by different groups of researchers and highlighted topics are proanthocyanidin chemistry, natural resources and the unique interactions between proanthocyanidincollagen and proanthocyanidin-MMPs in dentin. Besides, clinical applications of proanthocyanidin in the form of proanthocyanidin-containing adhesives, preconditioners and etchants have been reviewed. One hundred and twelve studies have been published in peer-reviewed journals from 1981 to 2017, all were comprised in this review, some of them have been actually proven to be promising from clinical point of view and others need further assessment before their adoption as clinically practicable protocols. PMID- 29176305 TI - Correlations between fracture load of zirconia implant supported single crowns and mechanical properties of restorative material and cement. AB - Zirconia implants that were restored with veneered zirconia displayed severe chipping rates of the restorations in clinical studies. Purpose of this study was to evaluate the fracture load of different zirconia implant supported monolithic crown materials (zirconia, alumina, lithium disilicate, feldspar ceramic and polymer-infiltrated ceramic) cemented with various cements (Harvard LuteCem SE, Harvard Implant Semi-permanent, Multilink Automix, VITA Adiva F-Cem). Flexural strength and fracture toughness of crown materials and compressive strength of the cements were measured. Fracture load values of crowns fabricated from lithium disilicate, feldspar ceramic and polymer-infiltrated ceramic were increased when cement with high compressive strength was used. Fracture loads for zirconia and alumina crowns were not influenced by the cement. Flexural strength and fracture toughness of the ceramics correlated linearly with the respective fracture load when using adhesive cement with high compressive strength. To achieve sufficient fracture load values, cementation with adhesive cement is essential for feldspar and polymer-infiltrated ceramic. PMID- 29176306 TI - Nitrogen Fixation Genes and Nitrogenase Activity of the Non-Heterocystous Cyanobacterium Thermoleptolyngbya sp. O-77. AB - Cyanobacteria are widely distributed in marine, aquatic, and terrestrial ecosystems, and play an important role in the global nitrogen cycle. In the present study, we examined the genome sequence of the thermophilic non heterocystous N2-fixing cyanobacterium, Thermoleptolyngbya sp. O-77 (formerly known as Leptolyngbya sp. O-77) and characterized its nitrogenase activity. The genome of this cyanobacterial strain O-77 consists of a single chromosome containing a nitrogen fixation gene cluster. A phylogenetic analysis indicated that the NifH amino acid sequence from strain O-77 was clustered with those from a group of mesophilic species: the highest identity was found in Leptolyngbya sp. KIOST-1 (97.9% sequence identity). The nitrogenase activity of O-77 cells was dependent on illumination, whereas a high intensity of light of 40 MUmol m-2 s-1 suppressed the effects of illumination. PMID- 29176310 TI - Urinary Disorders and Marfan Syndrome: A Series of 4 Cases. AB - Marfan syndrome is a genetic disease responsible for causing cardiovascular, eye and musculoskeletal damages. Urinary disorders are not common. We present 4 cases of chronic urinary tract symptoms, with 2 different pathophysiological processes. Three patients presented with spinal cord infarct following aortic dissection surgery. They were affected by an overactive bladder with detrusor overactivity and detrusor-sphincter dyssynergia. One patient complained of voiding dysfunction, possibly related to dural ectasia. Although a rare outcome, urinary disorders may appear in Marfan syndrome, by the occurrence of surgical complications in aortic surgery or possibility of sacral nerve root compression. If so, medical care is necessary to prevent uro-nephrological complications. PMID- 29176311 TI - Effect of Magnesium on Glomerular Filtration Rate and Recovery of Hypertension in Women with Severe Preeclampsia. AB - INTRODUCTION: Magnesium sulfate is used for preventing seizures in patients with severe preeclampsia. Previous studies have demonstrated that magnesium plays a significant role in the endothelial function and might have clinically beneficial vasodilating properties. OBJECTIVES: This study is aimed at evaluating the effect of magnesium sulfate on the glomerular filtration rate (GFR) during the first 24 h after delivery and during the duration of recovery from hypertension in preeclampsia. METHODS: Severe preeclamptic patients who had normal serum creatinine levels (0.4-0.8 mg/dL) were included in the study. Twenty-three women with severe preeclampsia were divided into groups of 9, 8, and 6, and given 1.0, 1.5, and 2.0 g/h of magnesium sulfate, respectively. Magnesium sulfate infusion was used as seizure prophylaxis for 24 h after delivery. The cystatin C-based GFR was monitored for 24 h, and the blood pressure was recorded for 12 weeks postpartum. RESULTS: Despite the minimal improvement of GFR 24-h after treatment initiation, survival analysis demonstrated a statistically significant relationship (log rank, p = 0.04) between magnesium dosage and recovery period from hypertension. The group receiving 2.0 g/h of magnesium experienced the shortest recovery period from hypertension (6.5 +/- 1.8 days). Meanwhile, the other groups required 66.0 +/- 26.9 and 48.3 +/- 15.6 days to recover after 1.0 and 1.5 g/h of magnesium infusion, respectively. CONCLUSION: Magnesium sulfate has no impact on GFR improvement during the first 24 h after delivery. However, magnesium maintenance infusion at 2.0 g/h is capable of preventing seizure by optimizing the therapeutic magnesium level (4.8-8.4 mg/dL) and shortening the hypertensive episode in preeclampsia. PMID- 29176312 TI - Validation of a Paediatric Speech and Language Screening (RALF). AB - BACKGROUND/AIMS: This study aims to analyse psychometric characteristics of the Portuguese Paediatric Speech and Language Screening (RALF) test. METHODS: 202 Portuguese children aged 3; 0-5; 11 were recruited from 4 kindergartens participating in this study. Reliability and validity (sensitivity and specificity) data were obtained and analysed. RESULTS: Content validity, analysed by an expert panel (general practitioner, kindergarten, teacher, nurse, and speech and language pathologist) revealed that the items were representative and relevant for the content the instrument intends to measure. Sensitivity values were 95, 96, and 83% and specificity values were 85, 84, and 71% for the age groups 3; 0-3; 11, 4; 0-4; 11, and 5; 0-5; 11, respectively. Internal consistency, calculated through Cronbach's alpha, was 0.7, 0.8, and 0.7, respectively. The inter-judge reliability (interclass correlation coefficient) was 0.951. The results ensure the content validity of RALF. Sensitivity and specificity values revealed that RALF could discriminate typical from disordered speech-language developing children. RALF also presented good internal consistency and excellent reliability. CONCLUSION: RALF is a reliable and valid screening instrument that health and educational professionals can use in Portuguese children to identify children who may need a speech-language diagnosis for consideration or referral to speech therapy services. PMID- 29176313 TI - Acute Kidney Injury Following Acute Ischemic Stroke and Intracerebral Hemorrhage: A Meta-Analysis of Prevalence Rate and Mortality Risk. AB - BACKGROUND: The epidemiology of acute renal dysfunction after stroke is routinely overlooked following stroke events. Our aim in this meta-analysis is to report the prevalence of acute kidney injury (AKI) following acute stroke and its impact on mortality. METHODS: A systematic literature search was performed on PubMed, EMBASE and Google Scholar for observational studies examining the prevalence and mortality risk of stroke patients with AKI as a complication. The pooled prevalence rates and odds ratios for mortality risk were calculated using subgroup analyses between the stroke subtypes: acute ischemic stroke (AIS) and intracerebral hemorrhage (ICH). RESULTS: A total of 12 studies (4,532,181 AIS and 615,636 ICH) were included. The pooled prevalence rate of AKI after all stroke types was 11.6% (95% CI 10.6-12.7). Subgroup analyses revealed that the pooled prevalence rate of AKI after AIS was greater but not statistically significantly different than ICH (19.0%; 95% CI 8.2-29.7 vs. 12.9%; 95% CI 10.3-15.5, p = 0.5). AKI was found to be a significant risk factor of mortality in AIS (adjusted OR [aOR] 2.23; 95% CI 1.28-3.89; I2 = 98.8%), whereas this relationship did not reach statistical significance in ICH (aOR 1.20; 95% CI 0.68-2.12; I2 = 74.2%). CONCLUSIONS: This meta-analysis provides evidence that AKI is a common complication following both AIS and ICH and it is associated with increased mortality following AIS but not ICH. This highlights the need for early assessment of renal function in the acute phase of AIS, in particular, and avoidance of factors than may induce AKI in vulnerable patients. PMID- 29176314 TI - Elevated Expression of Zinc Finger Protein 703 Promotes Cell Proliferation and Metastasis through PI3K/AKT/GSK-3beta Signalling in Oral Squamous Cell Carcinoma. AB - BACKGROUND/AIMS: Zinc finger protein 703 (ZNF703), initially identified as a novel oncogene in human breast cancer, is a member of the NET/NlZ family of zinc finger transcription factors. It is recognized that the overexpression of ZNF703 is associated with various types of human cancers, but the role and molecular mechanism of ZNF703 in oral squamous cell carcinoma (OSCC) are unknown. METHODS: ZNF703 expression levels were examined in OSCC tissues and non-cancerous tissues by qRT-PCR and immunohistochemistry (IHC). The molecular mechanisms of ZNF703 and its effects on cell growth and metastasis were explored in vitro and in vivo using the CCK8 assay, colony formation assay, cell cycle analysis, migration and invasion assays, wound-healing assay, western blotting and xenograft experiments in nude mice. RESULTS: In this study, ZNF703 was found to be upregulated in OSCC tissues compared to that in normal tissues at both mRNA and protein levels, and its expression level was closely correlated with the overall survival of patients with OSCC. Silencing of the ZNF703 gene in OSCC cells significantly inhibited cell growth and metastasis in vitro and in vivo. Conversely, the overexpression of ZNF703 in OSCC cells promoted cancer growth and metastasis in vitro. Mechanistically, ZNF703 activated the PI3K/AKT/GSK-3beta signalling pathway and its downstream effectors, thus regulating the cell cycle and epithelial mesenchymal transition (EMT). Furthermore, the promotive effects of ZNF703 on cellular proliferation and metastasis could be rescued by LY294002 (a PI3K specific inhibitor) and MK2206 (an Akt-specific inhibitor). CONCLUSION: The results show that ZNF703 promotes cell growth and metastasis through PI3K/Akt/GSK 3beta signalling in OSCC and that it may be a promising target in the treatment of patients with OSCC. PMID- 29176315 TI - Protective Effects of Antimuscarinics on the Bladder Remodeling After Bladder Outlet Obstruction. AB - BACKGROUND/AIMS: Overactive bladder associated with bladder outlet obstruction (BOO) is a highly prevalent condition, which is usually treated with antimuscarinics. However, the potential effects of antimuscarinics on the structure and function of bladder have not been investigated thus far. METHODS: Sprague-Dawley(R) rats accepted bladder neck obstruction surgery or sham surgery, and then received treatment of three different antimuscarinics (Solifenacin, Darifenacin, and Tolterodine) or vehicle. After 3, 6 and 12 weeks, the bladder function and structure were measured. The effect of antimuscarinics on cellular alteration in vitro was observed under mechanical stimulation. Bladder morphology were examined by immunohistochemistry, and the bladder function were investigated by cystometry and strip contractility test. The expression of muscarinic receptors and inflammatory cytokines were measured by PCR and Western blotting. RESULTS: Here we demonstrate, both in vitro and in vivo, that antimuscarinics are protective regulators for the bladder structure and function. Antimuscarinics decrease the weight of bladders with BOO. Antimuscarinics improve the voiding parameter and enhance the contraction of bladder smooth muscle. The results also show that antimuscarinics inhibit the proliferation of bladder smooth muscle cells both in vivo and in vitro, it can reduce the collagen deposition and inflammatory cytokines in bladders with BOO. During this process, the expression of M2 and M3 receptors was altered by antimuscarinics. CONCLUSION: Antimuscarinics could reverse the structural and functional changes of BOO bladder wall at cellular and tissue level, and the alteration of M2 and M3 receptors may be involved in this biological process. PMID- 29176316 TI - Toward Using a Smartwatch to Monitor Frailty in a Hospital Setting: Using a Single Wrist-Wearable Sensor to Assess Frailty in Bedbound Inpatients. AB - BACKGROUND: While various objective tools have been validated for assessing physical frailty in the geriatric population, these are often unsuitable for busy clinics and mobility-impaired patients. Recently, we have developed a frailty meter (FM) using two wearable sensors, which allows capturing key frailty phenotypes (weakness, slowness, and exhaustion), by testing 20-s rapid elbow flexion-extension test. OBJECTIVE: In this study, we proposed an enhanced automated algorithm to identify frailty using a single wrist-worn sensor. METHODS: The data collected from 100 geriatric inpatients (age: 78.9 +/- 9.1 years, 49% frail) were reanalyzed to validate the new algorithm. The frailty status of the participants was determined using a validated modified frailty index. Different FM phenotypes (31 features) including velocity of elbow rotation, decline in velocity of elbow rotation over 20 s, range of motion, etc. were extracted. A regression model, bootstrap with 2,000 iterations, and recursive feature elimination technique were used for optimizing the FM parameters and identifying frailty using a single wrist-worn sensor. RESULTS: A strong agreement was observed between two-sensor and wrist-worn sensor configuration (r = 0.87, p < 0.001). Results suggest that the wrist-worn FM with no demographic information still yields a high accuracy of 80.0% (95% CI: 79.7 80.3%) and an area under the curve of 87.7% (95% CI: 87.4-87.9%) to identify frailty status. Results are comparable with two-sensor configuration, where the observed accuracy and area under the curve were 80.6% (95% CI: 80.4-80.9%) and 87.4% (95% CI: 87.1-87.6%), respectively. CONCLUSION: The simplicity of FM may open new avenues to integrate wearable technology and mobile health to capture frailty status in a busy hospital setting. Furthermore, the reduction of needed sensors to a single wrist-worn sensor allows deployment of the proposed algorithm in the form of a smartwatch application. From the application standpoint, the proposed FM is superior to traditional physical frailty-screening tools in which the walking test is a key frailty phenotype, and thus they cannot be used for bedbound patients or in busy clinics where administration of gait test as a part of routine assessment is impractical. PMID- 29176317 TI - Downregulated MicroRNA-195 in the Bicuspid Aortic Valve Promotes Calcification of Valve Interstitial Cells via Targeting SMAD7. AB - BACKGROUND/AIMS: Aortic stenosis caused by leaflet calcification in the bicuspid aortic valve (BAV) is more accelerative than that in the tricuspid aortic valve (TAV). MicroRNA-195 (miR-195) is downregulated more in stenotic than in insufficient BAVs, but its expression in BAVs compared with TAVs is unclear. We aimed to investigate the roles of miR-195 and its calcification-related target SMAD7 in stenotic BAVs compared with those in TAVs. METHODS: Twenty-one stenotic BAV and 29 TAV samples were collected from surgical patients and examined for the expression of miR-195 and SMAD7 by RT-PCR. The samples were also assessed by western blotting and immunohistochemistry for the functional protein alteration associated with calcification. Dual-luciferase assay was performed to determine the putative target of miR-195 before the effects of miR-195 expression on osteogenic progression was demonstrated in cultured porcine valve interstitial cells (VICs). RESULTS: Compared with TAV, the expression of miR-195 was remarkably lower in the BAV leaflet with higher expression of SMAD7, which was then validated as a direct target of miR-195. Their negative correlation was then confirmed in cultured VICs. Under an osteogenic environment, the cellular calcification was promoted in miR-195-repressed VICs expressing higher BMP-2 and Runx2 and higher activity of MMP-2 compared with the controls. Finally, higher MMP-2 and MMP-9 expression and more collagen distribution were observed in BAV than TAV samples. CONCLUSIONS: miR-195 is downregulated more in stenotic BAV than TAV in this study. The downregulation of miR-195 is associated with valvular calcification via targeting SMAD7, which promotes the remodeling of the extracellular matrix. PMID- 29176319 TI - E3 Ubiquitin Ligase RNF125 Activates Interleukin-36 Receptor Signaling and Contributes to Its Turnover. AB - Signaling by the interleukin-36 receptor (IL-36R) is linked to inflammatory diseases such as psoriasis. However, the regulation of IL-36R signaling is poorly understood. Activation of IL-36R signaling in cultured cells results in an increased polyubiquitination of the receptor subunit, IL-1Rrp2. Treatment with deubiquitinases shows that the receptor subunit of IL-36R, IL-1Rrp2, is primarily polyubiquitinated at the K63 position, which is associated with endocytic trafficking and signal transduction. A minor amount of ubiquitination is at the K48 position that is associated with protein degradation. A focused siRNA screen identified RNF125, an E3 ubiquitin ligase, to ubiquitinate IL-1Rrp2 upon activation of IL-36R signaling while not affecting the activated IL-1 receptor. Knockdown of RNF125 decreases signal transduction by the IL-36R. Overexpression of RNF125 in HEK293T cells activates IL-36R signaling and increases the ubiquitination of IL-1Rrp2 and its subsequent turnover. RNF125 can coimmunoprecipitate with the IL-36R, and it traffics with IL-1Rrp2 from the cell surface to lysosomes. Mutations of Lys568 and Lys569 in the C-terminal tail of IL 1Rrp2 decrease ubiquitination by RNF125 and increase the steady-state levels of IL-1Rrp2. These results demonstrate that RNF125 has multiple regulatory roles in the signaling, trafficking, and turnover of the IL-36R. PMID- 29176318 TI - CCL2 is Upregulated by Decreased miR-122 Expression in Iron-Overload-Induced Hepatic Inflammation. AB - BACKGROUND/AIMS: Iron overload (IO) is accompanied by hepatic inflammation. The chemokine (C-C motif) ligand 2 (CCL2) mediates inflammation, and its overexpression is associated with IO. However, whether IO results in CCL2 overexpression in the liver and the underlying mechanisms are unclear. METHODS: We subjected mice to IO by administering intraperitoneal injections of dextran iron or by feeding mice a 3% dextran-iron diet to observe the effects of IO on miR-122/CCL2 expression through real-time qPCR and Western blot analysis. We also used indicators, including the expression of the inflammatory cytokine, the inflammation score based on H&E staining and the serum content of ALT and AST to evaluate the effects of IO on hepatic inflammation. Meanwhile, we observed the effects of vitamin E on IO-induced hepatic inflammation. In cells, we used 100 uMU FeSO4 or 30 uMU Holo-Tf to produce IO and observed the roles of miR-122 in regulating CCL2 expression by using miR-122 mimics or inhibitors to overexpress or inhibit miR-122. Then, we used a dual-luciferase reporter assay to prove that miR-122 regulates CCL2 expression through direct binding to its complementary sequence in the CCL2 mRNA 3'UTR. RESULTS: IO induces the downregulation of miR 122 and the upregulation of CCL2, as well as inflammatory responses both in vitro and in vivo. Although IO-induced oxidative stress is eliminated by the antioxidant vitamin E, IO-induced hepatic inflammation still exists, which probably can be explained by the fact that vitamin E has no effects on the miR 122/CCL2 pathway. In in vitro experiments, the overexpression and inhibition of miR-122 significantly reduced and increased CCL2 expression, respectively. The dual-luciferase reporter assay indicates that miR-122 binds CCL2 mRNA 3'UTR. CONCLUSION: We propose the roles of miR-122/CCL2 in IO-induced hepatic inflammation. Our studies should provide a new clue for developing clinical strategies for patients with IO. PMID- 29176320 TI - The Dual Regulatory Role of MiR-181a in Breast Cancer. AB - MicroRNAs (miRNAs) are a family of highly conserved noncoding single-stranded RNA molecules of 21 to 25 nucleotides. miRNAs silence their cognate target genes at the post-transcriptional level and have been shown to have important roles in oncogenesis, invasion, and metastasis via epigenetic post-transcriptional gene regulation. Recent evidence indicates that the expression of miR-181a is altered in breast tumor tissue and in the serum of patients with breast cancer. However, there are several contradicting findings that challenge the biological significance of miR-181a in tumor development and metastasis. In fact, some studies have implicated miR-181a in regulating breast cancer gene expression. Here we summarize the current literature demonstrating established links between miR-181a and human breast cancer with a focus on recently identified mechanisms of action. This review also aims to explore the potential of miR-181a as a diagnostic and/or prognostic biomarker for breast cancer and to discuss the contradicting data regarding its targeting therapeutics and the associated challenges. PMID- 29176321 TI - Clinical Characteristics and Prognostic Factors of Small Intestine Angiosarcoma: a Retrospective Clinical Analysis of 66 Cases. AB - BACKGROUND/AIMS: Primary angiosarcoma of the small intestine is a rare neoplasia, and there are limited data from systematic analyses. The aim of this study is to describe the clinical and pathological characteristics in addition to the prognostic factors for this rare neoplasia. METHODS: We retrospectively collected the clinical records and prognostic information of 66 patients with small intestine angiosarcoma reported between 1970 and 2017. We used the Chi-square test, the log-rank test, and Cox regression analyses to evaluate the data. RESULTS: There were 66 patients diagnosed with small intestine angiosarcoma. The onset age ranged from 24-92 years old. There were 24 patients diagnosed before the year 2000, and 42 patients were diagnosed after 2000. The data indicated that 49 cases were diagnosed as primary disease, and the remaining 15 cases were secondary disease. The main clinical symptoms were nonspecific and included gastrointestinal (GI) bleeding and abdominal pain. Additionally, we found multi center foci were one of the characteristics of this disease. Radiation-induced small intestine angiosarcoma (RSIA) is a special type of disease with a similar prognosis. This type was more frequent in females and decreased after the year 2000. We also found that GI bleeding was less common in RSIA cases. The log-rank test results revealed that old-age, poor differentiation, and GI bleeding were associated with worse prognosis. Surgical treatment showed a trend toward a prolonged survival time. However, the result was not statistically significant. Our results show treatment with adjuvant therapy improved prognosis. The multivariate Cox analysis demonstrated adjuvant therapy was an independent indicator of a favorable outcome in small intestine angiosarcoma patients. CONCLUSION: Pay attention to the unexplained gastrointestinal bleeding could lead to a faster diagnosis and control of small intestine angiosarcoma. Furthermore, treatments including adjuvant therapy can effectively improve the prognosis. PMID- 29176322 TI - Differential Expression Profiles of the Transcriptome in Breast Cancer Cell Lines Revealed by Next Generation Sequencing. AB - BACKGROUND/AIMS: As MCF-7 and MDA-MB-231 cells are the typical cell lines of two clinical breast tumour subtypes, the aim of the present study was to elucidate the transcriptome differences between MCF-7 and MDA-MB-231 breast cancer cell lines. METHODS: The mRNA, miRNA (MicroRNA) and lncRNA (Long non-coding RNA) expression profiles were examined using NGS (next generation sequencing) instrument Illumina HiSeq-2500. GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway analyses were performed to identify the biological functions of differentially expressed coding RNAs. Subsequently, we constructed an mRNA-ncRNA (non-coding RNA) targeting regulatory network. Finally, we performed RT-qPCR (real-time quantitative PCR) to confirm the NGS results. RESULTS: There are sharp distinctions of the coding and non-coding RNA profiles between MCF-7 and MDA-MB-231 cell lines. Among the mRNAs and ncRNAs with the most differential expression, SLPI, SOD2, miR-7, miR-143 and miR-145 were highly expressed in MCF-7 cells, while CD55, KRT17, miR-21, miR-10b, miR-9, NEAT1 and PICSAR were over-expressed in MDA-MB-231 cells. Differentially expressed mRNAs are primarily involved in biological processes of locomotion, biological adhesion, ECM-receptor interaction pathway and focal adhesion. In the targeting regulatory network of differentially expressed RNAs, mRNAs and miRNAs are primarily associated with tumour metastasis, but the functions of lncRNAs remain uncharacterized. CONCLUSION: These results provide a basis for future studies of breast cancer metastasis and drug resistance. PMID- 29176323 TI - MiR-148b, MiR-152/ALCAM Axis Regulates the Proliferation and Invasion of Pituitary Adenomas Cells. AB - BACKGROUND/AIMS: Aberrant expression of miRNA has been found in many tumor tissues to regulate the tumorigenesis by binding to the 3'- untranslated region (3'-UTR) of the target genes. The aim of this study is to investigate the role of miR-148b, miR-152/ALCAM axis in human pituitary adenomas (PAs). METHODS: First, we detected the expression level of miR-148b-3p and miR-152 in human PAs samples by using qRT-PCR. Then we studied the role of miR-148b-3p, miR-152 on human PAs cell proliferation, invasion and apoptosis by using MTS assay, Transwell invasion assay and Annexin V/PI Staining Test. To study the relationship between miR-148b 3p, miR-152 and activated leukocyte antigen molecule (ALCAM), we overexpressed miR-148-3p or miR-152 by transfecting specific mimics. Lucifearase reporter assay was then performed to confirm the target. Next, we studied the biological functions of ALCAM in human PAs cells. Finally, the role of miR-148b-3p, miR 152/ALCAM axis in PAs cells was studied. RESULTS: The expression level of miR-148 3p and miR-152 in invasive PAs samples was lower than those in noninvasive samples. Overexpression of miR-148b-3p, miR-152 could repress proliferation and invasion, and promote apoptosis. Moreover, miR-148b-3p and miR-152 could repress activated leukocyte antigen molecule (ALCAM) expression. Knockdown of ALCAM could repress proliferation and invasion and promote apoptosis. By contrary, overexpression of ALCAM promoted proliferation and invasion. Further, the rescue experiments indicated that overexpression of ALCAM significantly restored the proliferation, apoptosis, and invasion influenced by miR-148b-3p and miR-152. CONCLUSIONS: Our study suggests that miR-148b-3p, miR-152 may serve as suppressors in PAs through downregulating ALCAM expression. miR-148b, miR-152/ ALCAM axis may be a new therapeutic target in the future. PMID- 29176324 TI - Pituitary Dysfunction in Pediatric Patients with Optic Nerve Hypoplasia: A Retrospective Cohort Study (1975-2014). AB - BACKGROUND/AIMS: The risk factors for pituitary hormone dysfunction (PHD) in children with optic nerve hypoplasia (ONH) are not well understood. This study identified the type, timing, and predictors of PHD in children with ONH. METHODS: ONH patient charts were reviewed retrospectively. The incidence rate of PHD was calculated assuming a Poisson distribution. Predictors of PHD were identified through a multivariable Cox proportional hazards model. RESULTS: Among 144 subjects with ONH, 49.3% (n = 71) developed PHD over 614.7 person-years of follow up. The incidence was 11.55 (95% confidence interval [CI]: 9.02-14.57/100 person years). The median time to first PHD was 2.88 (interquartile range: 0.02-18.72) months. Eighty-two percent developed their first PHD by their 5th and 90% by their 10th birthday, and 89% within 5 years of ONH diagnosis. Prematurity (adjusted hazard ratio [aHR]: 0.33; 95% CI: 0.1-1.07), blindness (aHR: 1.72; 95% CI: 1.03-2.86), maternal substance abuse (aHR: 1.51; 95% CI: 0.91-2.48), abnormal posterior pituitary (aHR: 3.8; 95% CI: 2.01-7.18), and hypoplastic/absent anterior pituitary (aHR: 2.52; 95% CI: 1.29-4.91) were significant predictors of PHD. CONCLUSIONS: The clinical predictors of PHD included blindness, pituitary gland abnormalities, and maternal substance abuse. These predictors help clinical decision-making related to the need for and frequency of hormone testing in pediatric patients with ONH. PMID- 29176325 TI - Cav2.3 (R-Type) Calcium Channels are Critical for Mediating Anticonvulsive and Neuroprotective Properties of Lamotrigine In Vivo. AB - BACKGROUND/AIMS: Lamotrigine (LTG) is a popular modern antiepileptic drug (AED), however, its mechanism of action has yet to be fully understood, as it is known to modulate many members of several ion channel families. In heterologous systems, LTG inhibits Cav2.3 (R-type) calcium currents, which contribute to kainic-acid- (KA) induced epilepsy in vivo. To gain insight into the role of R type currents in LTG drug action in vivo, we compared the effects of LTG to topiramate and lacosamide in Cav2.3-deficient mice and controls on KA-induced seizures. METHODS: Behavioral seizure rating and quantitative electrocorticography were performed after injection of 20 mg/kg [and 30 mg/kg] KA. One hour before KA injection, mice were pretreated with either 30 mg/kg LTG, 50 mg/kg topiramate (TPM) or 30 mg/kg lacosamide (LSM). RESULTS: Ablation of Cav2.3 reduced total seizure scores by 28.6% (p=0.0012) and pretreatment with LTG reduced seizure activity of control mice by 23.2% (p=0.02). In Cav2.3-deficient mice LTG pretreatment increased seizure activity by 22.1% (p=0.018) and increased the percentage of degenerated CA1 pyramidal neurons (p=0.02). All three tested AEDs reduced seizure activity in control mice, however only the non-calcium channel modulating AED, LSM had an anticonvulsive effect in Cav2.3-deficient mice. Furthermore LTG altered electrocorticographic parameters differently in the two genotypes, decreasing relative power of ictal spikes in control mice compared to Cav2.3-defcient mice. CONCLUSION: These findings give first in vivo evidence for an essential role for Cav2.3 in LTG pharmacology and shed light on a paradoxical effect of LTG in their absence. Furthermore, LTG appears to promote ictal activity in Cav2.3-deficient mice resulting in increased neurotoxicity in the CA1 region. This paradoxical mechanism, possibly reflecting rebound hyperexcitation of pyramidal CA1 neurons after increased inhibition, may be key in understanding LTG-induced seizure aggravation, observed in clinical practice. PMID- 29176326 TI - High Systolic Blood Pressure after Successful Endovascular Treatment Affects Early Functional Outcome in Acute Ischemic Stroke. AB - BACKGROUND: Endovascular treatment (EVT) has been shown to significantly improve functional outcome in patients with acute large cerebral vessel occlusions. To date, no evidence-based recommendations on blood pressure management after successful EVT exist. Previous studies showed an association between high pre-EVT systolic blood pressure (SBP) and functional outcome, but do not answer the question on how to manage blood pressure after successful recanalization. The purpose of this study was to determine the role of blood pressure measurements as a predictor for early functional outcome in patients with successful EVT. METHODS: Prospectively derived data from patients with acute large vessel occlusion within the anterior circulation and EVT was analyzed in this monocentric study. Mean systolic- and maximum SBP as well as SBP-peaks have been obtained for the first 24 h after successful EVT. Predictive value of SBP for discharge modified Rankin Scale (mRS) <=2 has been investigated using logistic regression models. RESULTS: From 168 patients with successful EVT, 74 (44%) had a favorable outcome with an mRS <=2. Mean- (127 vs. 131 mm Hg, p = 0.035) and maximum SBP (157 vs. 169 mm Hg, p < 0.001) as well as the number of SBP-peaks (0 vs. 1.5, p = 0.004) were lower in patients with favorable outcomes. Multivariable logistic regression showed high mean- and maximum SBP to predict unfavorable outcomes. Cutoff mean SBP was 141 mm Hg and maximum SBP 159 mm Hg. CONCLUSIONS: High SBP in the first 24 h after recanalization of acute anterior cerebral vessel occlusions is associated with unfavorable functional outcome. Interventional studies are needed to determine the role of SBP management as a modifiable parameter in the early phase after successful EVT.

PMID- 29176328 TI - Cardiomyopathy-Associated Gene 1-Sensitive PKC-Dependent Connexin 43 Expression and Phosphorylation in Left Ventricular Noncompaction Cardiomyopathy. AB - BACKGROUND/AIMS: Cardiomyopathy-associated gene 1 (CMYA1) plays an important role in embryonic cardiac development, postnatal cardiac remodeling and myocardial injury repair. Abnormal CMYA1 expression may be involved in cardiac dysplasia and primary cardiomyopathy. Our study aims to establish the relationship between CMYA1 and Left ventricular noncompaction cardiomyopathy (LVNC) pathogenesis. METHODS: We explored the effects of CMYA1 on connexins (Cx), which contribute to gap junction intercellular communication (GJIC), and the underlying signaling pathway in human normal tissues, LVNC myocardial tissues and HL1 cells by means of western blotting, RT-qPCR, immunohistochemistry, immunofluorescence, co immunoprecipitation and scrape loading-dye transfer. RESULTS: CMYA1 expression was inversely associated with Cx43 and Cx40 expression, as determined by gap junction PCR array analysis. An increased expression and disordered distribution of CMYA1 at the intercalated discs in LVNC myocardial tissue was also observed. CMYA1 and Cx43 are co-expressed and interact in myocardial cells. CMYA1 expression was positively correlated with p-Cx43 (S368) via the Protein kinase C (PKC) signaling pathway in myocardial tissue and HL1 cells. The diffusion distance of Lucifer Yellow in the HL1 cells in which CMYA1 was over-expressed or knocked down was significantly less or more than that of the control group, respectively. CONCLUSION: Abnormal CMYA1 expression affects the expression and phosphorylation of Cx43 through the PKC signaling pathway, which is involved in the regulation of GJIC. CMYA1 participates in the molecular mechanism of LVNC pathogenesis. PMID- 29176329 TI - Inflammatory processes during acute respiratory distress syndrome: a complex system. AB - PURPOSE OF REVIEW: ARDS is a severe pulmonary disease characterized by inflammation. However, inflammation-directed therapies have yet failed to improve the outcome in ARDS patients. One of the reasons may be the underestimated complexity of inflammation. Here, we summarize recent insights into the complex interrelations between inflammatory circuits. RECENT FINDINGS: Gene expression analysis from animal models or from patients with ARDS, sepsis or trauma show an enormous number of differentially expressed genes with highly significant overlaps between the various conditions. These similarities, however, should not obscure the complexity of inflammation. We suggest to consider inflammation in ARDS as a system controlled by scale-free networks of genome-wide molecular interaction with hubs (e.g. NFkappaB, C/EBPbeta, ATF3), exhibiting nonlinear emergence and the ability to adapt, meaning for instance that mild and life threatening inflammation in ARDS are distinct processes. In order to comprehend this complex system, it seems necessary to combine model-driven simulations, data driven modelling and hypothesis-driven experimental studies. Recent experimental studies have illustrated how several regulatory circuits interact during pulmonary inflammation, including the resolution of inflammation, the inflammasome, autophagy and apoptosis. SUMMARY: We suggest that therapeutic interventions in ARDS should be based on a systems approach to inflammation. PMID- 29176330 TI - Dissipation of energy during the respiratory cycle: conditional importance of ergotrauma to structural lung damage. AB - PURPOSE OF REVIEW: To describe and put into context recent conceptual advances regarding the relationship of energy load and power to ventilator-induced lung injury (VILI). RECENT FINDINGS: Investigative emphasis regarding VILI has almost exclusively centered on the static characteristics of the individual tidal cycle tidal volume, plateau pressure, positive end-expiratory pressure, and driving pressure. Although those static characteristics of the tidal cycle are undeniably important, the 'dynamic' characteristics of ventilation must not be ignored. To inflict the nonrupturing damage we identify as VILI, work must be performed and energy expended by high stress cycles applied at rates that exceed the capacity of endogenous repair. Machine power, the pace at which the work performing energy load is applied by the ventilator, has received increasing scrutiny as a candidate for the proximate and integrative cause of VILI. SUMMARY: Although the unmodified values of machine-delivered energy or power (which are based on airway pressures and tidal volumes) cannot serve unconditionally as a rigid and quantitative guide to ventilator adjustment for lung protection, bedside consideration of the dynamics of ventilation and potential for ergotrauma represents a clear conceptual advance that complements the static parameters of the individual tidal cycle that with few exceptions have held our scientific attention. PMID- 29176331 TI - Management of work through the seasons of cancer survivorship. AB - PURPOSE OF REVIEW: Survival from cancer has expanded enormously over the past decades. It is estimated that 40-50% of all cancer survivors are of working age at time of diagnosis and thus potentially part of the labor force. The seasons of survivorship can be used as a steppingstone to describe issues regarding employability survivors are dealing with. RECENT FINDINGS: The acute survival stage begins at the point of diagnosis. Disclosure of diagnosis, and flexibility of both employers and (occupational) healthcare professionals are important factors in this stage. Extended survival starts when the survivor has completed the basic course of treatment. Survivors become aware that the old normality at work will be difficult to achieve. Problems like fear of recurrence, cognitive, and physical limitations might intensify during this stage and affect work ability. Permanent survival can be called long-term remission. Prospective studies on work-related outcomes and work-related interventions in this stage are rare. SUMMARY: It is important to improve our understanding of the seasons of survival and to explore concepts, such as employability, against the background of these seasons. This perspective may help both survivors and (occupational) healthcare professionals to develop better strategies for dealing with the difficult life event cancer represents in each specific stage. PMID- 29176332 TI - Transition to survivorship: can there be improvement? AB - PURPOSE OF REVIEW: The transition from primary cancer treatment to posttreatment follow-up care is seen as critical to the long-term health of survivors. However, relatively little attention has been paid to understanding this pivotal period. This review will offer a brief outline of the significant work surrounding this pivotal time published in the past year. RECENT FINDINGS: The growing number of cancer survivors has stimulated an emphasis on finding new models of care, whereby responsibility for survivorship follow-up is transitioned to primary care providers. A variety of models and tools have emerged for follow-up care. Survivorship care plans are heralded as a key component of survivorship care and a vehicle for supporting transition. Uptake of survivorship care plans and implementation of evidence-based models of survivorship care has been slow, hindered by a range of barriers. SUMMARY: Evaluation is needed regarding survivorship models in terms of feasibility, survivor friendliness, cost effectiveness, and achievement of sustainable outcomes. How, and when, to introduce plans for transition to the patient and determine transition readiness are important considerations but need to be informed by evidence. Additional study is needed to identify best practice for the introduction and application of survivorship care plans. PMID- 29176333 TI - Symptom cluster among patients with advanced heart failure: a review of its manifestations and impacts on health outcomes. AB - PURPOSE OF REVIEW: Assessment of symptom clustering is effective in enhancing care planning for symptom palliation in life-limiting disease. This review was aimed at identifying symptom cluster manifestation among advanced heart failure patients and to investigate the prognostic impact of the identified symptom clusters. RECENT FINDINGS: A systematic search of the literature identified 10 relevant articles. Two approaches were undertaken based on: correlations between symptoms and shared characteristics of patients' symptom profiles, to identify the symptom clusters. By comparing the findings for heart failure patients at an advanced disease stage and those who were not, the symptom clusters of advanced heart failure were found to have unique characteristics. In particular, the typical symptoms associated with cardiac decompensation are not clustered together. Instead, dyspnoea is clustered with emotional symptoms indicating that a distressing dyspnoeic attack may reinforce awareness of the life-limiting nature of the disease and arouse negative emotions. In addition, the debilitating heart failure-specific symptoms share the cause of the life-limiting aspects in compromising patient vitality. The strong positive association between symptom burden and cardiac event prompts the need for effective intervention to palliate not only typical but also atypical and emotional symptoms of advanced heart failure. SUMMARY: This review provides insight on potentially effective interventions for symptom palliation in advanced heart failure. PMID- 29176335 TI - Acute Angle-closure Glaucoma as a First Presentation of Coats' Disease: A Case Report. AB - PURPOSE: The purpose of this study was to report an unusual first manifestation of Coats' disease presenting as an acute angle-closure glaucoma attack in an adult patient. PATIENTS AND METHODS: A 37-year-old African woman presented to the emergency department with severe headache, ocular pain, and no light perception in the left eye. The left pupil was middilated and nonreactive, and the intraocular pressure (IOP) by applanation tonometry was 47 mm Hg. Slit-lamp examination revealed anterior subcapsular opacification (glaukomflecken), posterior synechiae, and total angle closure with iris bombe. A fundus examination revealed macular exudation, inferior vascular dilation, and tortuosity with peripheral telangiectasia and macroaneurysms, in addition to partial exudative retinal detachment involving the macula. On the basis of these findings, Coats' disease was diagnosed. RESULTS: The patient was treated with antiglaucoma medications and laser peripheral iridotomy to control the IOP, which had decreased to 21 mm Hg the following day. Diode laser transscleral cyclophotocoagulation was performed to further decrease the IOP. After completing a 360 degree laser, the IOP decreased to 8 mm Hg and then stabilized around 12 mm Hg. The vision remained no light perception; however, the patient felt major symptomatic relief. CONCLUSIONS: The present case describes acute angle-closure glaucoma as an initial presentation of Coats' disease in adults. Clinicians should be aware that this unique presentation in Coats' disease can occur even without retinal detachment. PMID- 29176336 TI - Managing hypertriglyceridemia: What can we learn from cardiovascular outcomes trials? AB - Cardiovascular (CV) risk remains in some patients who are treated with statins. Evidence supports a role for triglycerides (TGs) in CV disease. TG-lowering agent outcomes studies have been inconsistent, but eicosapentaenoic acid significantly reduced coronary events in hypercholesterolemic patients who were treated with statins. Ongoing outcomes studies will clarify the role of TG-lowering treatments in CV risk reduction. PMID- 29176334 TI - Preclinical Optimization of a CD20-specific Chimeric Antigen Receptor Vector and Culture Conditions. AB - Chimeric antigen receptor (CAR)-based adoptive T-cell therapy is a highly promising treatment for lymphoid malignancies, and CD20 is an ideal target antigen. We previously developed a lentiviral construct encoding a third generation CD20-targeted CAR but identified several features that required additional optimization before clinical translation. We describe here several improvements, including replacement of the immunogenic murine antigen-binding moiety with a fully human domain, streamlining the transgene insert to enhance lentiviral titers, modifications to the extracellular IgG spacer that abrogate nonspecific activation resulting from binding to Fc receptors, and evaluation of CD28, 4-1BB, or CD28 and 4-1BB costimulatory domains. We also found that restimulation of CAR T cells with an irradiated CD20 cell line boosted cell growth, increased the fraction of CAR-expressing cells, and preserved in vivo function despite leading to a reduced capacity for cytokine secretion in vitro. We also found that cryopreservation of CAR T cells did not affect immunophenotype or in vivo antitumor activity compared with fresh cells. These optimization steps resulted in significant improvement in antitumor activity in mouse models, resulting in eradication of established systemic lymphoma tumors in 75% of mice with a single infusion of CAR T cells, and prolonged in vivo persistence of modified cells. These results provide the basis for clinical testing of a lentiviral construct encoding a fully human CD20-targeted CAR with CD28 and 4-1BB costimulatory domains and truncated CD19 (tCD19) transduction marker. PMID- 29176337 TI - Ethical Resources. AB - There is no way to underestimate the importance of the countless ways that ethics impacts case managers and the patients we serve. In fact, solid ethical decisions are such an integral part of case management practice that the Commission for Case Manager Certification has increased its number of continuing education units required for recertification. Discussion and resources are outlined in the Editorial. PMID- 29176338 TI - Case Managers on the Front Lines of Ethical Dilemmas: Advocacy, Autonomy, and Preventing Case Manager Burnout. AB - PURPOSE: The purpose of this article is to examine how case managers are routinely confronted by ethical dilemmas within a fragmented health care system and given the reality of financial pressures that influence life-changing decisions. The Code of Professional Conduct for Case Managers (Code), published by the Commission for Case Manager Certification, acknowledges "case managers may often confront ethical dilemmas" (Code 1996, Rev. 2015). PRIMARY PRACTICE SETTINGS: The Code and expectations that professional case managers, particularly those who are board certified, will uphold ethical and legal practice apply to case managers in every practice setting across the full continuum of health care. IMPLEMENTATIONS FOR CASE MANAGEMENT PRACTICE: This discussion acknowledges the ethical dilemmas that case managers routinely confront, which empowers them to seek support, guidance, and resources to support ethical practice. In addition, the article seeks to raise awareness of the effects of burnout and moral distress on case managers and others with whom they work closely on interdisciplinary teams. PMID- 29176339 TI - Patient and Nurse Experiences in a Rural Chronic Disease Management Program: A Qualitative Evaluation. AB - PURPOSE: Rural status confounds chronic disease self-management. The purpose of this qualitative, descriptive study was to evaluate the nurse-led "Living Well" chronic disease management program reporting patient recruitment and retention issues since program initiation in 2013. The Chronic Care Model (CCM) was the guiding framework used to reinforce that interdisciplinary teams must have productive patient interactions for their program(s) to be sustainable. PRIMARY PRACTICE SETTING: A rural, Midwest county clinic's chronic disease management program. METHODOLOGY AND SAMPLE: Observations, interviews, and within- and across case coding were used. Patients' responses were analyzed to identify (1) reasons for recruitment and retention problems and (2) program elements that were viewed as successful or needing improvement. A convenience sample of 6 rural, English speaking adults (65 years or older, with no severe cognitive impairment) with at least one chronic condition was recruited and interviewed. RESULTS: Themes emerged related to nurse knowledge, availability, and value; peer support; overcoming barriers; adherence enhancement; and family/friends' involvement. Patients reported engagement in self-management activities because of program elements such as support groups and productive nurse-patient interactions. Interdisciplinary communication, commitment, and patient referral processes were identified as reasons for recruitment and retention issues. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: Findings substantiated that certain elements must be present and improved upon for future rural programs to be successful. Interdisciplinary communication may need to be improved to address recruitment and retention problems. It was clear from patient interviews that the nurse coordinators played a major role in patients' self-management adherence and overall satisfaction with the program. This is important to case management because results revealed the need for programs of this nature that incorporate the vital role of nurse coordinators and align with the CCM value of providing a supportive community health care resource for patients with chronic disease. PMID- 29176340 TI - Working With Transgender Individuals in Case Management Practice. AB - PURPOSE AND OBJECTIVES: To understand key concepts, effective communication strategies, and a broad range of health and human services for transgender persons in order to enhance the effectiveness of case management services. PRIMARY PRACTICE SETTINGS: Individuals who identify as transgender or gender variant. FINDINGS/CONCLUSIONS: Transgender persons have faced historic challenges in accessing health care services that are respectful, sensitive, and affirming. Case managers have the opportunity to serve as an advocate for these individuals by understanding effective communication strategies as well as medical, behavioral, and social services to support transgender persons through the transition process. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: To be effective with transgender persons, case managers need to know key terms and communications strategies, medical treatment options, behavioral health issues that need to be evaluated and addressed, and social services available to transgender persons. PMID- 29176341 TI - Community-Based Home Health Programs and Chronic Disease: Synthesis of the Literature. AB - PURPOSE OF STUDY: This article reviewed and evaluated literature on the various community-based home health programs and their effectiveness at preventing hospital admissions in adults. The research question addressed is as follows: Do community-based home health programs decrease hospital admissions in adult patients with chronic disease? PRIMARY PRACTICE SETTING: The primary practice setting evaluated in this review of the literature was community-based home health programs. METHODOLOGY AND SAMPLE: In this literature review, a seven-step review method was utilized to assess the evidence. Three electronic databases were used to conduct the initial search inquiry: CINAHL (Cumulative Index to Nursing and Allied Health Literature) Plus with Full Text, Medline, and PsycINFO. The search parameters include research from 2006 through 2016, English-language studies, and research published in peer-reviewed journals. The following search terms were used in multiple combinations: community-based health programs, chronic disease, and home. The primary sample population assessed was older adults with chronic disease. RESULTS: The research identified three common themes that influenced quality-of-life outcomes and health care utilization in participants of a community-based home health program. These themes were encouragement and emotional support, home visits, and multidisciplinary coordination of care. Additional concepts of depression and educational reinforcement were also noted. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: This literature review indicates that community-based home health programs are a viable solution to providing cost-effective health care to the adult population with chronic diseases. Community-based home health programs have been shown to have a positive impact on the quality of life and a decrease in health care utilization, including emergency department and primary care practitioner visits and hospital admissions, for adults with chronic disease.

PMID- 29176348 TI - Zika virus as a sexually transmitted pathogen. AB - PURPOSE OF REVIEW: Zika virus has recently emerged from an obscure mosquito-borne pathogen to an international public health concern. It is the first viral agent newly demonstrated to cause birth defects in several decades, and it is the only arbovirus now known to be transmitted sexually. The purpose of this review is to provide an overview of current understanding of sexual transmission of Zika virus and its possible clinical and public health consequences. RECENT FINDINGS: Sexual transmission of Zika virus has been reported from at least 13 countries without simultaneous mosquito-borne transmission; it is undoubtedly also occurring in countries with active arthropod transmission. Most published cases involve transmission from symptomatically infected men to women partners. Nevertheless, transmission from a symptomatic man to another man, from a symptomatic woman to a man, and from an asymptomatic man to a woman has also been reported. Sexual transmission has occurred before symptom onset, during illness, and after resolution of the source partner's symptoms. With the exception of a woman who developed symptomatic infection 44 days after onset of her husband's illness, nearly all instances reported to date have occurred within 20 days of the source partner's illness. Zika virus RNA has been detected in semen, saliva, blood, urine, and vaginal and cervical secretions; the length of time during which RNA can be detected varies widely across different body fluids but is especially lengthy in semen. Although semen has been found to contain ZIKV RNA for more than 180 days after illness onset, only a small proportion of samples with detectable RNA yield replicative virus whenever cultured. SUMMARY: Public health agencies have promulgated interim recommendations to prevent sexual transmission of Zika virus; however, much remains unknown regarding the duration of contagiousness and risk factors for transmission. Given the risk for birth defects, the greatest concern is for transmission of the virus to women who are pregnant or attempting to become pregnant. To prevent sexual transmission in general, couples are advised to use condoms or not have sex for at least 6 months from the start of the male partner's symptoms or the date he was diagnosed with Zika or after he has returned from an area with risk of ZIKV infection. Women who have symptomatic ZIKV infection or have traveled to an area of risk are advised to use condoms or avoid sex for 8 weeks from the start of the woman's symptoms or the date she was diagnosed with Zika or after the woman returns from the area of risk. PMID- 29176349 TI - Epidemiology of community-acquired bacterial meningitis. AB - PURPOSE OF REVIEW: The epidemiology of bacterial meningitis has been dynamic in the past 30 years following introduction of conjugated vaccines against Haemophilus influenzae type B, Streptococcus pneumoniae and Neisseria meningitidis. The purpose of this review is to describe recent developments in bacterial meningitis epidemiology. RECENT FINDINGS: The incidence of bacterial meningitis in Western countries (Finland, Netherlands, and the United States) gradually declined by 3-4% per year to 0.7-0.9 per 100 000 per year in the past 10-20 years. In African countries (Burkina Faso and Malawi), incidence rates are still substantially higher at 10-40 per 100 000 persons per year. Introduction of pneumococcal conjugate vaccines have not consistently decreased overall pneumococcal meningitis incidence because of serotype replacement. Following the introduction of serogroup A and C meningococcal vaccines, the incidence of meningococcal meningitis because of these serogroups strongly decreased. Novel outbreaks in the African meningitis belt by serogroup C and increased incidence of serogroup W in the United Kingdom and the Netherlands were observed recently. SUMMARY: Bacterial meningitis remains an important infectious disease, despite a gradual decline in incidence after large-scale vaccination campaigns. Further development of vaccines with broader coverage is important, as is continuous surveillance of bacterial meningitis cases. PMID- 29176350 TI - Low participation in organized colorectal cancer screening in France: underlying ethical issues. AB - International studies have shown a significant reduction in colorectal cancer (CRC) mortality following the implementation of organized screening programs, given a sufficient participation rate and adequate follow-up. The French national CRC screening program has been generalized since 2008 and targets 18 million men and women aged 50-74 years. Despite broad recommendations, the participation rate remains low (29.8%), questioning the efficiency of the program. A panel of experts was appointed by the French National Cancer Institute to critically examine the place of autonomy and efficiency in CRC screening and propose recommendations. In this paper, we explore the ethical significance of a public health intervention that falls short of its objectives owing to low take-up by the population targeted. First, we analyze the reasons for the low CRC screening participation. Second, we examine the models that can be proposed for public health actions, reconciling respect for the individual and the collective good. Our expert panel explored possible ways to enhance take-up of CRC screening within the bounds of individual autonomy, adapting awareness campaigns, and new educational approaches that take into account knowledge and analysis of sociocultural hurdles. Although public health actions must be universal, target actions should nonetheless be developed for nonparticipating population subgroups. PMID- 29176351 TI - Bacteremia in Patients With Liver Cirrhosis: Prevalence and Predictors of Multidrug Resistant Organisms. AB - GOALS: The objective of this study was to assess the prevalence and predictors of multidrug resistant organisms (MDRO) in cirrhotic patients with bacteremia at a large tertiary center in the United States. BACKGROUND: The epidemiology of bacteremia in patients with liver cirrhosis has not been well studied in the United States. STUDY: This case-case control study included 180 adults with liver cirrhosis hospitalized from 2011 to 2015. Case group 1 were patients with bacteremia due to a MDRO (n=30). Case group 2 were patients with bacteremia due to a non-MDRO (n=60). Control group comprised patients without bacteremia (n=90). MDRO was defined as bacteria that was nonsusceptible to >=1 agent in >=3 antimicrobial categories. RESULTS: Of the 90 bacteremia episodes, 44% were because of gram-positive bacteria, 50% were because of gram-negative bacteria, and 6% were polymicrobial. MDROs caused 30 of 90 (33%) bacteremia episodes, including methicillin-resistant Staphylococcus species [12% (11/90)], fluoroquinolone-resistant Enterobacteriaceae [10% (9/90)], and Enterococcus faecium [3% (3/90)]. Eight percent of Enterobacteriaceae produced extended spectrum beta-lactamases. Four independent predictors of MDROs were identified: nonwhite race [adjusted odds ratio (aOR), 3.35; 95% confidence interval (CI), 1.19-9.38], biliary cirrhosis (aOR, 11.75; 95% CI, 2.08-66.32), blood cultures obtained >48 hours after hospital admission (aOR, 6.02; 95% CI, 1.70-21.40), and recent health care exposure (aOR, 9.81; 95% CI, 2.15-44.88). CONCLUSIONS: A significant proportion of bacteremia in cirrhotic patients was due to MDROs at a large US tertiary care center. Local epidemiology data and identification of risk factors associated with MDROs may help with optimal empiric antibiotic selection. PMID- 29176352 TI - New science and treatment paradigms for atopic dermatitis. AB - PURPOSE OF THE REVIEW: The prevalence of atopic dermatitis is increasing in industrialized countries for unclear reasons. One theory centers on reduced exposure to microbes during infancy and childhood. Alterations in the epidermal permeability barrier, place certain patients at risk for the immunological dysfunction seen in atopic dermatitis. This review examines current research pertaining to the epidermal permeability barrier, the cutaneous microbiome, and the immunology of atopic dermatitis. New collaborative research has led to evidence-based management guidelines. RECENT FINDINGS: Increased skin barrier permeability and dysfunction of innate and adaptive immunity cause atopic dermatitis. Genetic and environmental factors leading to decreased filaggrin underlie many cases of atopic dermatitis. Defective epidermal barrier function allows for an increased density of Staphylococcus aureus and a subsequent shift in adaptive immunity to a type 2 immune response. Multiple evaluation and management guidelines have been published based on current available evidence. These guidelines highlight state of the art management of seven main areas: inflammation, infection, irritation, itch, ichthyosis (dry skin), immunological influences, and impeding (comorbid) conditions. SUMMARY: Pediatricians are central to the successful diagnosis and management of atopic dermatitis. Increased basic and clinical research and well published clinical guidelines will lead to improved outcomes for the patients and families affected by this chronic relapsing disorder. PMID- 29176353 TI - New developments in immunotherapy for pediatric leukemia. AB - PURPOSE OF REVIEW: Immunotherapy for the treatment of cancer has advanced at a tremendous pace over the last decade. In this review, we provide an overview of recent progress in immunotherapy for the treatment of leukemia, focusing on antibody-drug conjugates (ADC), bi-specific T-cell engagers (BiTE), and chimeric antigen receptor (CAR) T cells. RECENT FINDINGS: Ongoing clinical trials of CAR T cells directed against CD19 have produced complete remission rates as high as 93%, prompting global multicenter phase 2 trials and the first FDA approval of a CAR T-cell therapy. Insights into cytokine release syndrome, a toxicity of CAR T cell therapy, and the cause for relapse after CAR T-cell therapy are evolving. The bispecific antibody blinatumomab and the ADCs inotuzumab and gemtuzumab have also recently received FDA approval for ALL and AML, respectively, moving these agents into a more prominent role in the relapse setting. SUMMARY: The use of immunotherapy for leukemia has been successful in creating durable remissions for multiply relapsed and refractory patients who previously had little chance of cure. The ongoing clinical and preclinical work continues to advance our understanding of these immune-based therapies, and will shape the next generation of clinical trials. PMID- 29176354 TI - Pediatric avulsion fractures of pelvis: current concepts. AB - PURPOSE OF REVIEW: Provide the reader with an evidence-based update on the importance of accurate diagnosis of commonly missed avulsion fractures of pelvis apophyses, the necessary imaging studies, the feared complications and the recent treatment recommendations. RECENT FINDINGS: Accurate diagnosis of avulsion fractures of pelvis apophyses is high yield as misdiagnosis leads to improper treatment. They should be differentiated from muscle strain and apophysitis. These fractures are usually associated with good outcomes; however, missed diagnosis can lead to further displacement, nonunion, functional limitation, femoroacetabular impingement and infection. A/P and frog lateral pelvis radiograph show the fracture and its displacement in the majority of cases. Conservative treatment, consisting of a short period of rest and immobilization followed by passive stretching then progressive resisted activity before return to sports, is recommended in minimally displaced avulsions. Surgical treatment is favored in displaced fractures (>15 mm), as it is associated with quicker return to sports. SUMMARY: Treating physicians should keep a high index of suspicion in pediatric and adolescent patients presenting with typical clinical exam findings. Pelvic Anteroposterior and frog leg radiographs are often diagnostic. Missed diagnosis can aggravate the prognosis of a usually benign condition. Adequate medical or surgical treatment should then be administered. PMID- 29176355 TI - What is the chance that a patella dislocation will happen a second time: update on the natural history of a first time patella dislocation in the adolescent. AB - PURPOSE OF REVIEW: Patellar instability occurs mainly in young patients and shows a high incidence of concomitant cartilage injuries. Recently there has been a strong attempt to identify risk factors and enhance imaging techniques to detect patients with an increased risk for recurrent patella dislocation.We describe current findings on factors associated with recurrent patella dislocation in the adolescent. RECENT FINDINGS: Trochlear dysplasia, patellar height, patellar tilt, tibial tuberosity-trochlear groove distance, skeletal maturity, and history of contralateral patellar dislocation are well known significant risk factors for recurrence in adolescent patients. Predictive models to calculate risk of recurrence have been reported recently. The Patellar Instability Severity Score was the first to include demographic and anatomic factors, which is of major value when counseling patients and relatives. SUMMARY: Several classification systems to predict the rate of recurrence after primary patella dislocation have been presented over the last years. Anatomic risk factors such as skeletal immaturity, trochlear morphology, patellar height, patellar tilt, and elevated tibial tuberosity-trochlear groove distance have been investigated. However, there is still a lack of knowledge as to how single risk factors or their interaction with each other may contribute. PMID- 29176356 TI - Evolving paradigms for new agent development in pediatric oncology. AB - PURPOSE OF REVIEW: To discuss considerations of new paradigms for clinical drug development in pediatric oncology that incorporate our expanding knowledge and complexity of molecular alterations associated with cancer; advances in cancer immunology and cellular therapy; the increasing number of new anticancer drugs, therapeutic approaches, and potential combinations; and recent initiatives by regulatory agencies to improve access to safe and effective therapies. RECENT FINDINGS: Cancer in children and adolescents is a rare event with significant long-term impact on individuals and society. Using multimodality therapy, stratified by patient and disease characteristics, the cure rate for childhood cancer exceeds 80%. Cancer genomics has transformed anticancer drug development. Understanding the genetic basis of pediatric cancers and the use of genomics for risk stratification has changed the focus of drug development from cytotoxic drugs to targeted therapeutic approaches. Advances in cancer immunology, immune checkpoint blockade, and cellular therapy offer novel approaches to harness T cells to treat cancer. To improve the outcome for children and adolescents with cancer and accelerate drug development, understanding drug and target interactions in preclinical models of pediatric cancer should be coupled with efficient clinical trial designs that incorporate biomarker selection, assessment of toxicity and drug exposure, and improved measures of response. SUMMARY: Clinical trials for children and adolescents with cancer evaluate cytotoxic drugs, molecularly target drugs, immunotherapy as well as combination therapies. The framework for oncology clinical trials will continually adapt to improve efficiency of trials and evaluate new therapeutic approaches. PMID- 29176357 TI - Human-papillomavirus-related disease in pediatrics. AB - PURPOSE OF REVIEW: Human papillomaviruses (HPVs) account for a number of distinct disease entities in pediatrics, ranging from common warts to the stigmatizing condyloma acuminata to life-threatening respiratory papillomatosis. Although there is still a lack of consensus on treatment for each of these HPV-related diseases, scientific investigation continues to progress. Increasing prevention of HPV-related disease with further vaccination and development of new vaccines continues to be the best medical strategy. RECENT FINDINGS: Although high-quality evidence for treatment of HPV-related disease is still lacking, several new studies have been published in recent years that have refined opinions on therapy. Novel treatments continue to be developed, including new vaccines to further coverage for other strains. SUMMARY: HPV-related disease in pediatrics is associated with societal stigmatization and a high level of morbidity. Greater understanding of the distinct diseases and high-quality research is necessary to enhance treatment selection in the coming future. PMID- 29176358 TI - Recent advances in pediatric oncology. PMID- 29176359 TI - Comparison of the Effectiveness of a Virtual Simulator With a Plastic Arm Model in Teaching Intravenous Catheter Insertion Skills. AB - The objective of this study was to compare the effectiveness of a virtual intravenous simulator with a plastic arm model in teaching intravenous catheter insertion skills to nursing students. We used a randomized controlled quasi experimental trial design and recruited 65 students who were assigned to the experimental (n = 33) and control (n = 32) groups using the simple random sampling method. The experimental group received intravenous catheterization skills training on the virtual intravenous simulator, and the control group received the same training on a plastic model of a human arm. Data were collected using the personal information form, intravenous catheterization knowledge assessment form, Intravenous Catheterization Skill Test, Self-Confidence and Satisfaction Scale, and Fear Symptoms Scale. In the study, the mean scores in the control group were 20.44 for psychomotor skills, 15.62 for clinical psychomotor skills, 31.78 for self-confidence, and 21.77 for satisfaction. The mean scores in the experimental group were 45.18 for psychomotor skills, 16.28 for clinical psychomotor skills, 34.18 for self-confidence, and 43.89 for satisfaction. The results indicated that psychomotor skills and satisfaction scores were higher in the experimental group, while the clinical psychomotor skills and self-confidence scores were similar in both groups. More students in the control group reported experiencing symptoms such as cold and sweaty hands, significant restlessness, and tense muscles than those in the experimental group. PMID- 29176361 TI - Active targeted delivery of immune therapeutics to lymph nodes. AB - PURPOSE OF REVIEW: Organ transplantation is a life-saving procedure and the only option for patients with end-organ failure. Immune therapeutics have been key to the success of organ transplantation. However, immune therapeutics are still unable to eliminate graft rejection and their toxicity has been implicated in poorer long-term transplant outcomes. Targeted nanodelivery has the potential to enhance not only the therapeutic index but also the bioavailability of the immune therapeutics. One of the key sites of immune therapeutics delivery is lymph node where the priming of immune cells occur. The focus of this review is on nanomedicine research to develop the targeted delivery of immune therapeutics to lymph nodes for controlling immune activation. RECENT FINDINGS: As nanomedicine creates its niche in clinical care, it provides novel immunotherapy platforms for transplant recipients. Draining lymph nodes are the primary loci of immune activation and represent a formidable site for delivery of wide variety of immune therapeutics. There have been relentless efforts to improve the properties of nanomedicines, to have in-depth knowledge of antigen and drug loading, and, finally, to explore various routes of passive and active targeted delivery to lymph nodes. SUMMARY: The application of nanotechnology principles in the delivery of immune therapeutics to the lymph node has created enormous excitement as a paradigm shifting approach that enables targeted delivery of a gamut of molecules to achieve a desired immune response. Therefore, innovative strategies that improve their efficacy while reducing their toxicity are among the highest unmet needs in transplantation. PMID- 29176360 TI - Intergenerational Consequences: Women's Experiences of Discrimination in Pregnancy Predict Infant Social-Emotional Development at 6 Months and 1 Year. AB - OBJECTIVE: Racial/ethnic and socioeconomic disparities in infant development in the United States have lifelong consequences. Discrimination predicts poorer health and academic outcomes. This study explored for the first time intergenerational consequences of women's experiences of discrimination reported during pregnancy for their infants' social-emotional development in the first year of life. METHODS: Data come from a longitudinal study with predominantly Black and Latina, socioeconomically disadvantaged, urban young women (N = 704, Mage = 18.53) across pregnancy through 1 year postpartum. Women were recruited from community hospitals and health centers in a Northeastern US city. Linear regression analyses examined whether women's experiences of everyday discrimination reported during pregnancy predicted social-emotional development outcomes among their infants at 6 months and 1 year of age, controlling for potentially confounding medical and sociodemographic factors. Path analyses tested if pregnancy distress, anxiety, or depressive symptoms mediated significant associations. RESULTS: Everyday discrimination reported during pregnancy prospectively predicted greater inhibition/separation problems and greater negative emotionality, but did not predict attention skills or positive emotionality, at 6 months and 1 year. Depressive symptoms mediated the association of discrimination with negative emotionality at 6 months, and pregnancy distress, anxiety, and depressive symptoms mediated the association of discrimination with negative emotionality at 1 year. CONCLUSION: Findings support that there are intergenerational consequences of discrimination, extending past findings to infant social-emotional development outcomes in the first year of life. It may be important to address discrimination before and during pregnancy and enhance support to mothers and infants exposed to discrimination to promote health equity across the life span. PMID- 29176362 TI - Significance of biologics in renal transplantation: past, present, and future. AB - PURPOSE OF REVIEW: Finding the right immunosuppressive approach for the individual transplant patient is of utmost importance. In truth, a 'one size fits all' does not exist, and as patients differ, so should therapeutic suppression of the immune system be individualized. For over three decades, biologics have been a central component of transplant immunosuppression. Our growing knowledge of immunological processes combined with biotechnological advances is leading to promising new therapeutic concepts and possibilities including novel biologics. Use of biologics may be appropriate at various phases of kidney transplantation, from desensitization and induction to maintenance therapy and management of acute rejection. Their mechanisms of action include depleting or modulating immune cells, eliminating preformed antibodies, and inhibiting the complement system. Herein, we summarize the current approaches to applying 'established' biologics to prevent and treat allograft rejection in kidney transplantation. We also provide insights into new developments and possible future directions. RECENT FINDINGS: A number of candidate biologics were found to be efficacious in more recent preclinical and early phase clinical trials. Their properties are outlined and their potential for future utilization discussed. SUMMARY: The extraordinary capabilities of biologics are undisputed and our technological progress offers unprecedented opportunities to devise new agents and refine old ones. However, the rationale for their use in kidney allograft recipients must be rigorously examined in every case and, given the significant risk of early and late-onset adverse effects, the risk-to-benefit ratio carefully balanced. We also need to expand and use our knowledge of the underlying physiology of allograft rejection to adjust the characteristics of therapeutic biologics and thus harness their full potential for the benefit of our patients.

PMID- 29176366 TI - Identification of a novel homozygous TBC1D24 mutation in a Turkish family with DOORS syndrome. PMID- 29176367 TI - Rare NaV1.7 variants associated with painful diabetic peripheral neuropathy. AB - Diabetic peripheral neuropathy (DPN) is a common disabling complication of diabetes. Almost half of the patients with DPN develop neuropathic pain (NeuP) for which current analgesic treatments are inadequate. Understanding the role of genetic variability in the development of painful DPN is needed for improved understanding of pain pathogenesis for better patient stratification in clinical trials and to target therapy more appropriately. Here, we examined the relationship between variants in the voltage-gated sodium channel NaV1.7 and NeuP in a deeply phenotyped cohort of patients with DPN. Although no rare variants were found in 78 participants with painless DPN, we identified 12 rare NaV1.7 variants in 10 (out of 111) study participants with painful DPN. Five of these variants had previously been described in the context of other NeuP disorders and 7 have not previously been linked to NeuP. Those patients with rare variants reported more severe pain and greater sensitivity to pressure stimuli on quantitative sensory testing. Electrophysiological characterization of 2 of the novel variants (M1852T and T1596I) demonstrated that gain of function changes as a consequence of markedly impaired channel fast inactivation. Using a structural model of NaV1.7, we were also able to provide further insight into the structural mechanisms underlying fast inactivation and the role of the C-terminal domain in this process. Our observations suggest that rare NaV1.7 variants contribute to the development NeuP in patients with DPN. Their identification should aid understanding of sensory phenotype, patient stratification, and help target treatments effectively. PMID- 29176368 TI - Changes in Case-Mix and Health Outcomes of Medicare Fee-for-Service Beneficiaries and Managed Care Enrollees During the Years 1992-2011. AB - BACKGROUND: Recent studies suggest that managed care enrollees (MCEs) and fee-for service beneficiaries (FFSBs) have become similar in case-mix over time; but comparisons of health outcomes have yielded mixed results. OBJECTIVE: To examine changes in differentials between MCEs and FFSBs both in case-mix and health outcomes over time. DESIGN: Temporal study of the linked Health and Retirement Study (HRS) and Medicare data, comparing case-mix and health outcomes between MCEs and FFSBs across 3 time periods: 1992-1998, 1999-2004, and 2005-2011. We used multivariable analysis, stratified by, and pooled across the study periods. The unit of analysis was the person-wave (n=167,204). SUBJECTS: HRS participants who were also enrolled in Medicare. MEASURES: Outcome measures included self reported fair/poor health, 2-year self-rated worse health, and 2-year mortality. Our main covariate was a composite measure of multimorbidity (MM), MM0-MM3, defined as the co-occurrence of chronic conditions, functional limitations, and/or geriatric syndromes. RESULTS: The case-mix differential between MCEs and FFSBs persisted over time. Results from multivariable models on the pooled data and incorporating interaction terms between managed care status and study period indicated that MCEs and FFSBs were as likely to die within 2 years from the HRS interview (P=0.073). This likelihood remained unchanged across the study periods. However, MCEs were more likely than FFSBs to report fair/poor health in the third study period (change in probability for the interaction term: 0.024, P=0.008), but less likely to rate their health worse in the last 2 years, albeit at borderline significance (change in probability: -0.021, P=0.059). CONCLUSIONS: Despite the persistence of selection bias, the differential in self-reported fair/poor status between MCEs and FFSBs seems to be closing over time. PMID- 29176369 TI - Payments and Utilization of Immunization Services Among Children Enrolled in Fee for-Service Medicaid. AB - OBJECTIVE: To examine the association between state Medicaid vaccine administration fees and children's receipt of immunization services. METHODS: The study used the 2008-2012 Medicaid Analytic eXtract data and included children aged 0-17 years and continuously enrolled in a Medicaid fee-for-service plan in each study year. Analyses were restricted to 8 states with a Medicaid managed care penetration rate <75%. Linear regressions were used to estimate the probability of children making >=1 vaccination visit and the numbers of vaccination visits in the year as a function of state Medicaid vaccine administration fees, age group, sex, race/ethnicity, state unemployment rate, state managed-care penetration rate, and state and year-fixed effects. RESULTS: A total of 1,678,288 children were included. In 2008-2012, the average proportion of children making >=1 vaccination visit per year was 31% and the mean number of vaccination visits was 0.9. State Medicaid reimbursements for vaccine administration was positively associated with immunization service utilization; for every $1 increase in the payment amount, the probability of children making >=1 vaccination visit increased by 0.72 percentage point (95% confidence interval, 0.23-1.21; P=0.01), representing a 2% increase from the mean and the number of vaccination visits increased by 0.03 (95% confidence interval, -0.00 to 0.06; P<0.1). The estimated effect was greater among younger children. CONCLUSION: Higher Medicaid reimbursements for vaccine administration were associated with increased proportion of children receiving immunization services. PMID- 29176370 TI - Percutaneous Transhepatic Y-shaped Stent Placement in Portal-superior Mesenteric Vein Tumor Thrombosis Before Right Colectomy. AB - Portal-mesenteric tumor thrombosis represents a rare finding in patients with colorectal cancers. To our knowledge this is the first report of a patient diagnosed as having a wide stenosing right colon cancer with portal-superior mesenteric vein tumor thrombosis at the time of diagnosis, who was treated before surgery by positioning a percutaneous transhepatic Y-shaped stent through the main portal vein and the superior mesenteric vein. Percutaneous interventional procedures have gained worldwide acceptance for improving the symptoms of portal hypertension, because of their minimal invasiveness and high success rates with low number of complications. A multidisciplinary approach is mandatory in order to choose the best therapeutic option for the patients and the importance of a strong collaboration between interventional radiologist and surgeon has to be considered. PMID- 29176371 TI - Percutaneous Image-guided Surgery Training: Model IHU-DAICIM. AB - The evolution of guided imaging surgery is well known in recent years. As the field of action becomes more specific, learning and teaching are also more specific. State-of-the-art medical training should be mandatory in the field of general medicine and surgery in particular. In this work, we report on how to create a model for the formation of guided surgery by images in a simple and fast way, and its implementation by young surgeons. Pig models have been used in which collections made by bovine small intestine and simulated tumor lesions have been placed. Several types of image-guided procedures have been performed. No major complications were found during the development of the model or during its use. It is possible to develop a quick, simple, and safe living training model that can be used immediately after preparation. PMID- 29176372 TI - Application of Laparoscopic Gastrectomy in Obese Patients (BMI>=30 kg/m2) with Gastric Cancer: A Comparison With Open Gastrectomy Regarding Short-term Outcomes. AB - OBJECTIVE: Few studies have compared the surgical outcomes of laparoscopic (LG) and open (OG) gastrectomy in obese patients (BMI>=30 kg/m) with gastric cancer. The current study aimed to investigate the short-term outcomes of LG in this group of patients. METHODS: A total of 33 LG cases and 23 OG cases (BMI>=30 kg/m) were identified from our gastric cancer database. Clinicopathologic features, operative details, laboratory examination, and postoperative outcomes were compared between both groups. Regression analysis was used to determine the effects of BMI on intraoperative outcomes. RESULTS: The 2 groups had comparable clinicopathologic characteristics. LG was associated with significantly lesser blood loss, whereas both also groups had a similar operative time, and number of harvested lymph nodes. However, regression analysis indicated that increased BMI affected the operative time and blood loss in patients that underwent OG but had little effect on patients who received LG. The elevation of inflammatory factors (WBC, CRP) was lower in LG than in OG, postoperatively. Postoperative hepatic (alanine aminotransferase, total bilirubin, albumin) and renal (creatinine, blood urea nitrogen) functions in the LG group were not worse than in the OG group. The time to first flatus, initiation of diet, hospitalization, and postoperative complications seemed superior in LG than in OG, but these differences were not statistically significant. CONCLUSION: LG can be safely performed in obese gastric cancer patients. Compared with conventional OG, LG is less invasive and is characterized by less blood loss and milder surgical trauma. LG is also less adversely affected by increased BMI. PMID- 29176373 TI - Obstructive sleep apnea and bariatric surgical guidelines: summary and update. AB - PURPOSE OF REVIEW: Increasing numbers of bariatric surgical procedures and the high prevalence of obstructive sleep apnea (OSA) in this population have resulted in a growing interest in the perioperative management of OSA in bariatric surgery. This review provides a summary of the first consensus guideline on this topic as well as an update of the newest literature available. RECENT FINDINGS: All bariatric patients should be screened for OSA and obesity hypoventilation syndrome (OHS) to reduce the risk of perioperative complications. Intraoperative precautions are preoxygenation, induction and intubation in ramped position, continuous positive airway pressure (CPAP) and positive end-expiratory pressure during induction, maintenance of low tidal volumes during surgery, multimodal anesthesia and analgesia with avoidance of opioids and extubation when patients are free of neuromuscular blockage. CPAP therapy and continuous monitoring with a minimum of pulse oximetry is recommended in the early postoperative period. SUMMARY: Multiple precautions exist to minimize the risk of cardiopulmonary complications and to enhance recovery after surgery. A combination of these procedures seems to provide optimal perioperative care of OSA patients undergoing bariatric surgery. Nearly 75% of recommendations are based on low quality of evidence, indicating the high value of experts' opinion and potential for future research. PMID- 29176374 TI - Intraoperative vasoplegia: methylene blue to the rescue! AB - PURPOSE OF REVIEW: To evaluate the efficacy, dosing, and safety of methylene blue (MTB) in perioperative vasoplegic syndrome (VS). RECENT FINDINGS: Vasoplegic syndrome is a state of persistent hypotension with elevated cardiac output, low filling pressures, and low systemic vascular resistance (SVR). It occurs in up to 25% of patients undergoing cardiac surgery with cardiopulmonary bypass, can last up to 72 h, and is associated with a high mortality rate. MTB has been found to increase SVR and decrease vasopressor requirements in vasoplegic syndrome by inhibiting nitric oxide synthase, thus limiting the generation of nitric oxide, while inhibiting activation of soluble guanylyl cyclase and preventing vasodilation. MTB has been used in postgraft reperfusion during liver transplantation and anaphylaxis in a limited number of cases. Additionally, this medication has been used in septic shock with promising results, but similar to the cardiac surgical population, the effects of MTB administration on clinical outcomes has yet to be elucidated. SUMMARY: MTB should be considered during vasoplegic syndrome in cardiac surgery with cardiopulmonary bypass and usage may be more effective in an early critical window, prior to end-organ hypoperfusion. Other perioperative scenarios of MTB use show promise, but additional studies are required to develop formative conclusions. PMID- 29176376 TI - Anticipated and unanticipated difficult airway management. AB - PURPOSE OF REVIEW: Management of difficult airway is far from optimal despite of continuous progress in science and technology. The purpose of this review is to summarize the current research in the field and bring readers up to date. RECENT FINDINGS: New technologies for intubation make providers more confident to handle difficult airways, but there is lack of evidence indicating the reduction in incidence of 'cannot intubate cannot ventilate (CICV)'. Optimization of mask ventilation should reduce the incidence of difficult mask ventilation but it is greatly underappreciated. Even optimization of preoxygenation is not directly associated with any decreased incidence of difficult airway, but it prolongs time of safe apnea oxygenation; therefore, is likely to improve the outcome of the patients if CICV occurs. SUMMARY: Improvement of managing difficult airway relies on optimized mask ventilation, utilization of the appropriate tools for intubation, maximization of the safe apnea oxygenation time, prompt surgical airway in response to severe hypoxia in case effective noninvasive interventions are not achievable. It seems that a simplified and concise algorithm of difficult airway management needs to be established in order to enable providers to easily remember and execute. PMID- 29176375 TI - Vitamin C in sepsis. AB - PURPOSE OF REVIEW: This narrative review summarizes recent insights into the role of vitamin C in sepsis. RECENT FINDINGS: Septic shock remains a major source of morbidity and mortality in critically ill patients. Although many nutritional supplements have previously been tested unsuccessfully, vitamins are still being explored as a therapeutic option in septic patients. In particular, vitamin C containing regimens as adjunctive therapy in sepsis have received much attention. SUMMARY: In-vitro evidence supports a critical role for vitamin C in cellular mechanisms relevant to the pathophysiology of sepsis. However, whether this justifies therapeutic use of vitamin C in septic patients remains uncertain. PMID- 29176377 TI - Pulmonary effects of aging. AB - PURPOSE OF REVIEW: As the population ages, the increase in chronic illnesses among patients with decreasing lung function will pose a major public health challenge. Determining which elderly patients are fit for surgery is an increasingly important skill. Anesthetic care of elderly patients requires an understanding of the effects that chronic diseases have on normal age-related changes in physiology and function. Postoperative respiratory complications are significantly increased in patients over 65 years of age, especially those with preexisting diseases. RECENT FINDINGS: Advanced age is associated with changes in the immunity of the pulmonary system. Dysregulation of pro-inflammatory mediators and antimicrobial defense systems contribute to a reduction in pulmonary function and its response to infections. Aging is also associated with a disruption of the function of alveolar macrophages, neutrophils, and natural killer cells. SUMMARY: Aging can increase the risk of postoperative complications because of a loss of physiologic reserve and airway defenses. These limitations may only become apparent after the stressors of surgery and anesthesia. PMID- 29176378 TI - Clinical characteristics and outcomes of patients with coronary artery spasm who initially presented with acute myocardial infarction. AB - BACKGROUND: The long-term clinical outcomes of coronary artery spasm (CAS) patients presented with acute myocardial infarction (AMI) compared to those who did not present with AMI has rarely been investigated. METHODS: From November 2004 to May 2014, a total of 3360 patients who were confirmed as CAS by the acetylcholine (Ach) provocation test and without significant coronary lesion were retrospectively analyzed. AMI was an initial presentation in 34 patients [CAS myocardial infarction (MI) group], and not in other 3326 patients (CAS group). The clinical outcomes up to 5 years were compared between the two groups. RESULTS: Baseline characteristics and cardiovascular risk factors did not differ between the two groups, except the higher smoking rate in CAS-MI group (38.2 vs. 23.5%, P=0.046). During a mean follow-up period of 1211+/-583 days, the cumulative incidence of recurrent angina [hazard ratio (HR): 2.71; 95% confidence interval (CI): 1.20-6.13; P=0.016], MI (HR: 33.89; 95% CI: 8.76-131.1; P<0.001) and major adverse cardiovascular events (MACE; HR: 10.94; 95% CI: 3.83-31.22; P<0.001) were significantly higher in the CAS-MI group. After propensity score matched analysis (1 : 5 matching; n=186, C-statistic=0.834), the incidences of recurrent angina (HR; 4.68; 95% CI: 1.62-13.5; P=0.004) and MACE (HR: 12.2; 95% CI: 2.23-67.3; P=0.003) remained higher in the CAS-MI group. CONCLUSION: The CAS MI group patients were associated with higher incidence of recurrent angina, MI, and MACE compared to CAS group patients. More intensive antispastic medication might be needed for these patients, and further study will be necessary to determine which treatment can improve the prognosis of CAS-MI patients. PMID- 29176379 TI - Thrombin generation estimates the anticoagulation effect of direct oral anticoagulants with significant interindividual variability observed. AB - : Direct oral anticoagulants (DOACs) are increasingly being used, primarily due to their drug stability and patient convenience. Although these drugs have been evaluated to be well tolerated in numerous clinical trials, their impact on in vivo anticoagulation effect, variability and therapeutic drug level remains unknown. Hence, we aim to study the effect and variability of DOACs on thrombin generation via the calibrated automated thrombogram. Anonymized coagulation specimens from outpatients on warfarin were collected. Pooled normal plasma samples were spiked with increasing concentrations of dabigatran, rivaroxaban and apixaban. Similarly, plasma samples with normal coagulation profiles were spiked with two concentrations each of dabigatran, rivaroxaban and apixaban. Thrombin generation via calibrated automated thrombogram was run using the above samples and compared with a dataset of normal controls. Increasing international normalized ratio was associated with a reduction of endogenous thrombin potential (ETP) and thrombin peak and increasing lag time. Factor Xa inhibitors produced a flattened thrombin generation curve with a reduction of thrombin peak and relative preservation of ETP. Direct thrombin inhibitors produced a reduction of both ETP and thrombin peak and increasing lag time. Seventy-one citrated plasma samples (26 dabigatran, 21 rivaroxaban and 24 apixaban) were evaluated. The two concentrations produced a reduction of thrombin generation parameters with significant interindividual variability compared with neat plasma of 35-93, 13-31 and 18-71% and for dabigatran, rivaroxaban and apixaban, respectively. Thrombin generation can measure the anticoagulation effect of commonly used DOACs, with each drug having a unique thrombin generation profile. The variability noted using the same concentration suggests significant interindividual pharmacodynamic differences, which maybe relevant with respect to efficacy as well as bleeding side effects. Further delineation of the modifiers of interindividual differences is required in the in-vivo setting. PMID- 29176380 TI - Congenital hypofibrinogenemia in pregnancy: a report of 11 cases. AB - : To investigate the obstetrical outcomes and plasma concentrations of fibrinogen (FIB) in patients with congenital hypofibrinogenemia in pregnancy, 11 cases with hypofibrinogenemia in pregnancy were analyzed retrospectively. The demographic database, bleeding tendency, plasma levels of FIB throughout pregnancy, peripartum management, as well as, maternal and neonatal outcomes were assessed. FIB levels in our patients remained relatively stable throughout the pregnancy. The mean FIB levels during the three trimesters of pregnancy were 75.7 +/- 43.9 (25-148), 67.6 +/- 33.7 (22-146), and 77.9 +/- 29.2 (32-148) mg/dl, respectively. Twelve full-term deliveries were achieved using FIB replacement therapy only on the group of labor or cesarean deliveries. The postpartum courses were unremarkable without hemorrhagic or thrombotic complications. Five out of twelve neonates were diagnosed with low levels of FIB in 6 weeks after birth. The pregnancies were uneventful with no signs of bleeding in these congenital hypofibrinogenemia women. Vaginal delivery, instead of cesarean section, may be the superior choice. Successful maternal and neonatal outcomes could be achieved by accurate monitoring of the FIB levels and adequate supportive therapy. PMID- 29176381 TI - Barriers to the Prescription of Psychological Strategies by Strength and Conditioning Specialists. AB - Radcliffe, JN, Comfort, P, and Fawcett, T. Barriers to the prescription of psychological strategies by strength and conditioning specialists. J Strength Cond Res 32(7): 1948-1959, 2018-The purpose of this article was to explore the barriers to strength and conditioning coaches integrating psychological strategies within the strength and conditioning practice. The sample of accredited strength and conditioning coaches comprised 10 subjects working within the United Kingdom, 3 within the United Sates, and 5 within Australia offering a cross section of experience from a range sporting disciplines and educational backgrounds. Subjects were interviewed using semistructured interviews and thematic clustering was used using interpretative phenomenological analysis to identify common themes. It was evident that not incorporating psychological strategies into strength and conditioning practice could be attributed to either internal, personally governed beliefs, or external, environmentally governed situations. Internal sources consisted of insufficient knowledge either regarding the value of psychological strategies or methods of implementing such techniques; in addition, the implementation of psychological techniques was outside the remit of the coach and difficulty existed in demonstrating the effectiveness of interventions. External causes consisted of a lack of time, insufficient control and authority of training session content, and athletes' negative perceptions. Recommendations are made on the basis of eliminating the observed barriers to the inclusion of psychological strategies. This included the use of education programs for both strength and conditioning coaches and organizational gatekeepers and the suggestion for increased collaboration with qualified psychologists. PMID- 29176382 TI - Independent and Combined Effects of Weight Status and Maturation on Aerobic Fitness in Adolescent School Aged Males. AB - This study aimed to examine the independent and combined effects of pubertal and weight status on concurrent measurements of peak oxygen (VO2peak) in school aged adolescent males. The final sample included 49 boys (12.3 +/- 0.8 years). VO2peak was derived from an incremental progressive maximal protocol using a motorized treadmill. In addition, maximal oxygen uptake was estimated from a 20-m shuttle run test. Static allometric models were obtained as an alternative to performance output per unit of size descriptors. Weight status had a significant effect on VO2peak using simple ratio standards per unit of body mass with adolescents classified as overweight and obese (OWOB) attaining lower values of VO2peak. A similar trend was noted for the allometric models adopting body mass (BM; mL.kgBM.min), stature (L.m.min) and fat-free mass (FFM; mL.kgFFM.min). Findings also suggest the influence and interaction of pubertal and weight status on absolute values of VO2peak. Considering the data obtained, linear equations to estimate VO2peak from the 20-m shuttle run test should not be applied to boys that are OWOB as it will produce inaccurate assessments of cardiorespiratory fitness and penalize those who are heavier. Equations for VO2peak prediction need to be specific for pubertal status and preferably consider FFM as a body size descriptor. PMID- 29176383 TI - Effect of Jump Interval Training on Kinematics of the Lower Limbs and Running Economy. AB - Ache-Dias, J, Pupo, JD, Dellagrana, RA, Teixeira, AS, Mochizuki, L, and Moro, ARP. Effect of jump interval training on kinematics of the lower limbs and running economy. J Strength Cond Res 32(2): 416-422, 2017-This study analyzed the effects of the addition of jump interval training (JIT) to continuous endurance training (40-minute running at 70% of peak aerobic velocity, 3 times per week for 4 weeks) on kinematic variables and running economy (RE) during submaximal constant-load running. Eighteen recreational runners, randomized into control group (CG) or experimental group (EG) performed the endurance training. In addition, the EG performed the JIT twice per week, which consisted of 4-6 bouts of continuous vertical jumping (30 seconds) with 5-minute intervals. The oxygen consumption (V[Combining Dot Above]O2) during the submaximal test (performed at 9 km.h) was similar before (EG: 38.48 +/- 2.75 ml.kg.min; CG: 36.45 +/- 2.70 ml.kg.min) and after training (EG: 37.42 +/- 2.54 ml.kg.min; CG: 35.81 +/- 3.10 ml.kg.min). No effect of training, group, or interaction (p > 0.05) was found for RE. There was no interaction or group effect for the kinematic variables (p > 0.05). Most of the kinematic variables had a training effect for both groups (support time [p <= 0.05]; step rate [SR; p <= 0.05]; and step length [SL; p <= 0.05]). In addition, according to the practical significance analysis (percentage chances of a better/trivial/worse effect), important effects in leg stiffness (73/25/2), vertical stiffness (73/25/2), SR (71/27/2), and SL (64/33/3) were found for the EG. No significant relationship between RE and stiffness were found for EG and CG. In conclusion, the results suggest that JIT induces important changes in the kinematics of the lower limbs of recreational runners, but the changes do not affect RE. PMID- 29176384 TI - Use of Mobile Applications to Collect Data in Sport, Health, and Exercise Science: A Narrative Review. AB - Peart, DJ, Balsalobre-Fernandez, C, and Shaw, MP. Use of mobile applications to collect data in sport, health, and exercise science: A narrative review. J Strength Cond Res XX(X): 000-000, 2018-Mobile devices are ubiquitous in the population, and most have the capacity to download applications (apps). Some apps have been developed to collect physiological, kinanthropometric, and performance data; however, the validity and reliability of such data is often unknown. An appraisal of such apps is warranted, as mobile apps may offer an alternative method of data collection for practitioners and athletes with money, time, and space constraints. This article identifies and critically reviews the commercially available apps that have been tested in the scientific literature, finding evidence to support the measurement of the resting heart through photoplethysmography, heart rate variability, range of motion, barbell velocity, vertical jump, mechanical variables during running, and distances covered during walking, jogging, and running. The specific apps with evidence, along with reported measurement errors are summarized in the review. Although mobile apps may have the potential to collect data in the field, athletes and practitioners should exercise caution when implementing them into practice as not all apps have support from the literature, and the performance of a number of apps have only been tested on 1 device. PMID- 29176385 TI - Positional Differences in Running and Nonrunning Activities During Elite American Football Training. AB - Ward, PA, Ramsden, S, Coutts, AJ, Hulton, AT, and Drust, B. Positional differences in running and nonrunning activities during elite American football training. J Strength Cond Res XX(X): 000-000, 2017-The aim of this investigation was to describe differences in training loads between position groups within professional American football. Integrated micro technology data were collected on 63 NFL football players during an American football training camp. Five key metrics (total distance, high-speed distance, player load (PL), PL per minute, and total inertial movement analysis [IMA]) served to quantify both running and nonrunning activities. Players were classified into position groups (defensive back [DB], defensive linemen [DL], linebacker, offensive linemen [OL], quarterback, running back, tight end, and wide receiver [WR]). Training sessions were identified by their relationship to the upcoming match (e.g., -4, -3, and 2). Running and nonrunning activities varied between position groups relative to the training day. Differences in total distance between DB and WR were observed to be unclear across the 3 training days (game day [GD] -4: 74 +/- 392 m; GD -3: 122 +/- 348 m; and GD -2: -222 +/- 371 m). However, moderate to large differences were observed between these 2 positions and the other positional groups. A similar relationship was observed in PL and PL per minute, with the DB and WR groups performing greater amounts of load compared with other positional groups. Differences in high-speed distance varied across positional groups, indicating different outputs based on ergonomic demands. The OL and DL groups ran less but engaged in a higher amount of nonrunning activities (total IMA) with differences ranging from moderate to large across the 3 training days. Total IMA differences between offensive and defensive linemen were unclear on GD -4 (-4 +/- 9) and GD 2 (-2 +/- 8) and likely moderate on GD -3 (-9 +/- 9). Positional differences with regard to running and nonrunning activities highlight the existence of position specific training within a training microcycle. In addition, total IMA provides a useful metric for quantifying sport-specific movements within the game of American football. PMID- 29176386 TI - Sex-Related Differences in The Accuracy of Estimating Target Force Using Percentages of Maximal Voluntary Isometric Contractions Versus Ratings of Perceived Exertion During Isometric Muscle Actions. AB - The purpose of this study was to examine sex-related differences in the accuracy of estimating actual target force and to compare the accuracy of estimating actual target force using percentages of maximal voluntary isometric contraction (MVIC) or ratings of perceived exertion (RPE) values during isometric leg flexion and leg extension muscle actions. Twenty adults, 10 women and 10 men, (mean +/- SD age: 22.9 +/- 2.9 yrs) completed pretest MVICs to calculate actual target force values at 10, 30, 50, 70, and 90% of MVIC. Additional trials were then randomized for estimating actual target force using percentages of MVIC or RPE values during isometric leg flexion or leg extension. For isometric leg flexion, the women and men overestimated (p<=0.05) the actual target force at 10% for the percentage of MVIC and RPE trial and underestimated the actual target force at 90% for the RPE trial. For isometric leg extension, the women overestimated the actual target force at 10% for the percentage of MVIC trial and RPE trial. The men overestimated actual target force at 10% and 30% for the percentage of MVIC trial and overestimated actual target force at 10% during the RPE trial for isometric leg extension. Also, the men underestimated actual target force at 90% for both the percentage of MVIC trial and RPE trial. Men require more familiarization than women to accurately estimate isometric leg extension force values. Caution should be used when estimating force production as a percentage of MVIC or RPE value for training prescriptions. PMID- 29176387 TI - Effects of Plyometric and Directional Training on Speed and Jump Performance in Elite Youth Soccer Players. AB - Beato, M, Bianchi, M, Coratella, G, Merlini, M, and Drust, B. Effects of plyometric and directional training on speed and jump performance in elite youth soccer players. J Strength Cond Res 32(2): 289-296, 2018-Soccer players perform approximately 1,350 activities (every 4-6 seconds), such as accelerations/decelerations and changes of direction (CODs) during matches. It is well established that COD and plyometric training have a positive impact on fitness parameters in football players. This study analyzed the effect of a complex COD and plyometric protocol (CODJ-G) compared with an isolated COD protocol (COD-G) training on elite football players. A randomized pre-post parallel group trial was used in this study. Twenty-one youth players were enrolled in this study (mean +/- SD; age 17 +/- 0.8 years, mass 70.1 +/- 6.4 kg, and height 177.4 +/- 6.2 cm). Players were randomized into 2 different groups: CODJ-G (n = 11) and COD-G (n = 10), training frequency of 2 times a week more than 6 weeks. Sprint 10, 30, and 40 m, long jump, triple hop jump, and 505 COD test were considered. Exercise-induced within-group changes in performance for both CODJ-G and COD-G: long jump (effect size [ES] = 0.32 and ES = 0.26, respectively) and sprint 10 m (ES = -0.51 and ES = -0.22, respectively), after 6 weeks of training. Moreover, CODJ-G reported substantially better results (between-group changes) in long jump test (ES = 0.32). In conclusion, this study showed that short-term protocols (CODJ-G and COD-G) are important and able to give meaningful improvements on power and speed parameters in a specific soccer population. CODJ-G showed a larger effect in sprint and jump parameters compared with COD-G after the training protocol. This study offers important implications for designing COD and jumps training in elite soccer. PMID- 29176388 TI - The Effect of Citrulline Malate Supplementation On Muscle Fatigue Among Healthy Participants. AB - The focus of the investigation was to examine the effects of citrulline malate on muscular fatigue in healthy, recreationally trained participants. Twelve participants (males = 6; females = 6) (24.1 +/- 3.9 yrs) visited the lab on three separate days all separated by one week. Each visit consisted of consuming one of three treatments: placebo (PLA), citrulline malate (8 g) (CM), and control (CON) in which no drink mixture was consumed. For each day of testing, participants consumed assigned treatment and performed one high-intensity exercise trial consisting of squats, lunge jumps, squat jumps, and lateral jumps. Participants performed the exercises in the listed order, which was designated as one round. Each participant performed 3 rounds, with the work to rest ratio being 20 sec work, 30 sec rest. A one min rest was given between rounds. A pre/post-exercise isokinetic leg extension test was performed to measure for peak power, peak torque, and rate of fatigue. Additionally, blood lactate was obtained pre/post exercise. There were no treatment or interaction effects (p > 0.05) for peak torque, peak power, rate of fatigue, or blood lactate accumulation. However, there was a statistical significant decrease from pre/post-ex for peak torque (p = 0.003), peak power (p = 0.003), and rate of fatigue (p = 0.001). Additionally, lactate accumulation did increase significantly from pre/post-ex (p = 0.0001). Lastly, neither total work nor final heart rate was statistical significant between the treatments (p > 0.05). Citrulline malate was not effective in improving performance or alleviating fatigue following a high-intensity exercise session. PMID- 29176390 TI - Methodological factors affecting quantification of blood pressure variability: a scoping review. AB - OBJECTIVES: Blood pressure (BP) variability (BPV) may offer independent prognostic information. However, data supporting this notion are inconsistent, and this may be due to the wide variety of methodologies used for measuring BPV. A systematic analysis on the effect of BPV methodologies on BPV itself has never been undertaken and was the aim of this study. We also sought to determine the effect of participant characteristics on BPV. METHODS: A scoping review process was used to identify the effect of BPV methodologies on BPV magnitude. Key methodological factors assessed were the number of BP readings or visits used to quantify BPV and the duration of BP monitoring. In addition, the relationship between age and mean BP level on BPV was investigated. Analyses were performed across studies that measured BPV over the short-term (using 24-h BP), mid-term (using home BP in the morning, evening or day-to-day) and long-term (using visit to-visit clinic BP). RESULTS: Data were extracted from 96 studies. The number of BP readings and visits used to quantify BPV were positively associated with mid term and long-term BPV. Duration was weakly associated with mid-term (morning) BPV. Age was positively associated with long-term and mid-term (day-to-day), but not short-term BPV. Mean BP level was positively associated with BPV, except mid term BPV (morning and evening). CONCLUSION: The methodology used to quantify BPV, as well as age and mean BP level, affects the magnitude of BPV itself. This highlights the need to standardize BPV protocols, particularly regarding the number of BP readings and visits. PMID- 29176389 TI - Contemporary genetic testing in inherited cardiac disease: tools, ethical issues, and clinical applications. AB - : Inherited cardiac diseases comprise a wide and heterogeneous spectrum of diseases of the heart, including the cardiomyopathies and the arrhythmic diseases in structurally normal hearts, that is, channelopathies. With a combined estimated prevalence of 3% in the general population, these conditions represent a relevant epidemiological entity worldwide, and are a major cause of cardiac morbidity and mortality in the young. The extraordinary progress achieved in molecular genetics over the last three decades has unveiled the complex molecular basis of many familial cardiac conditions, paving the way for routine use of gene testing in clinical practice. In current practice, genetic testing can be used in a clinically affected patient to confirm diagnosis, or to formulate a differential diagnosis among overlapping phenotypes or between hereditary and acquired (nongenetic) forms of disease. Although genotype-phenotype correlations are generally unpredictable, a precise molecular diagnosis can help predict prognosis in specific patient subsets and may guide management. In clinically unaffected relatives, genetic cascade testing is recommended, after the initial identification of a pathogenic variation, with the aim of identifying asymptomatic relatives who might be at risk of disease-related complications, including unexpected sudden cardiac death. Future implications include the identification of novel therapeutic targets and development of tailored treatments including gene therapy. This document reflects the multidisciplinary, 'real-world' experience required when implementing genetic testing in cardiomyopathies and arrhythmic syndromes, along the recommendations of various guidelines. PMID- 29176391 TI - The relationship of all-cause mortality to average on-treatment systolic blood pressure is significantly related to baseline systolic blood pressure: implications for interpretation of the Systolic Blood Pressure Intervention Trial study. AB - BACKGROUND: The SPRINT study demonstrated that targeting systolic blood pressure (SBP) less than 120 mmHg was associated with lower cardiovascular event and mortality rates. In the LIFE study, however, a lower achieved SBP was associated with increased mortality. Mean baseline SBP in SPRINT was 140 mmHg and a third of the population had a baseline SBP 132 mmHg or less, raising the question of whether the lower baseline SBP in SPRINT could in part account for these differences. METHODS: All-cause mortality during 4.8 +/- 0.9 years follow-up was examined in relation to tertiles of achieved on-treatment average SBP in patients with baseline SBP of 25th percentile or less versus greater than 25th percentile value of 164 mmHg in 7998 nondiabetic hypertensive patients with ECG left ventricular hypertrophy randomly assigned to losartan-based or atenolol-based treatment. Average on-treatment SBP less than 142 mmHg (lowest tertile) and average SBP 142 mmHg to less than 152 mmHg (middle tertile) were compared with average SBP at least 152 mmHg (highest tertile and reference group). RESULTS: In the overall population, there was a significant interaction between baseline SBP 164 mmHg or less and average on-treatment SBP less than 142 mmHg in Cox analysis (chi = 15.48, P < 0.001). Among patients with baseline SBP greater than 164 mmHg, in multivariate Cox analyses adjusting for other potential predictors of mortality and a propensity score for having baseline SBP 164 mmHg or less and compared with average on-treatment SBP at least 152 mmHg, average on-treatment SBP less than 142 mmHg was associated with 32% higher mortality (hazard ratio 1.32, 95% CI 1.01-1.65), whereas average SBP of 142 mmHg to less than 152 mmHg was associated with 24% lower mortality (hazard ratio 0.76, 95% CI 0.59-0.98). In contrast, among patients with baseline SBP 164 mmHg or less, both average on treatment SBP less than 142 mmHg (hazard ratio 0.60, 95% CI 0.36-0.99) and average SBP of 142 mmHg to less than 152 mmHg (hazard ratio 0.51, 95% CI 0.30 0.89) were associated with significantly lower mortality compared with average SBP of at least 152 mmHg. CONCLUSION: Achievement of an average SBP less than 142 mmHg was associated with reduced mortality in patients with baseline SBP 164 mmHg or less but with increased mortality in those with higher baseline SBP in LIFE. These findings suggest that the lower mortality associated with a lower targeted SBP in SPRINT may not be applicable to patients with considerably higher baseline SBP than SPRINT patients. Further study is necessary to better understand these findings. CLINICAL TRIALS REGISTRATION: http://clinicaltrials.gov/ct/show/NCT00338260?order=1.

PMID- 29176394 TI - Hearing Loss in Children With Otitis Media With Effusion: Actual and Simulated Effects on Speech Perception. AB - OBJECTIVE: Conductive hearing loss simulations have attempted to estimate the speech-understanding difficulties of children with otitis media with effusion (OME). However, the validity of this approach has not been evaluated. The research aim of the present study was to investigate whether a simple, frequency specific, attenuation-based simulation of OME-related hearing loss was able to reflect the actual effects of conductive hearing loss on speech perception. DESIGN: Forty-one school-age children with OME-related hearing loss were recruited. Each child with OME was matched with a same sex and age counterpart with normal hearing to make a participant pair. Pure-tone threshold differences at octave frequencies from 125 to 8000 Hz for every participant pair were used as the simulation attenuation levels for the normal-hearing children. Another group of 41 school-age otologically normal children were recruited as a control group without actual or simulated hearing loss. The Mandarin Hearing in Noise Test was utilized, and sentence recall accuracy at four signal to noise ratios (SNR) considered representative of classroom-listening conditions were derived, as well as reception thresholds for sentences (RTS) in quiet and in noise using adaptive protocols. RESULTS: The speech perception in quiet and in noise of children with simulated OME-related hearing loss was significantly poorer than that of otologically normal children. Analysis showed that RTS in quiet of children with OME-related hearing loss and of children with simulated OME-related hearing loss was significantly correlated and comparable. A repeated-measures analysis suggested that sentence recall accuracy obtained at 5-dB SNR, 0-dB SNR, and -5-dB SNR was similar between children with actual and simulated OME-related hearing loss. However, RTS in noise in children with OME was significantly better than that for children with simulated OME-related hearing loss. CONCLUSIONS: The present frequency-specific, attenuation-based simulation method reflected the effects of OME-related hearing loss on speech perception impairment in quiet environments. In noisy environments, the simulation method could only approximately estimate the effects of OME-related hearing loss on speech perception in typical classroom noise levels. Children with OME-related hearing loss may develop compensatory strategies to reduce the effects of hearing loss in adverse listening environments. PMID- 29176395 TI - Integrated safety summary for trifluridine/tipiracil (TAS-102). AB - Trifluridine/tipiracil, an oral treatment combining trifluridine (an antineoplastic thymidine-based nucleoside analog) and tipiracil hydrochloride (a thymidine phosphorylase inhibitor), led to significant improvement in overall survival in metastatic colorectal cancer (mCRC) patients refractory to standard therapy in the phase III RECOURSE trial. Here, we report an integrated summary of the safety of trifluridine/tipiracil. The main safety analysis includes integrated data from the RECOURSE and J003 studies (safety data group 2) of patients with refractory mCRC receiving trifluridine/tipiracil at the recommended starting dose: 35 mg/m twice daily for 5 days with 2 days' rest for 2 weeks, followed by a 14-day rest (one cycle). Integrated data from a larger group of mCRC patients receiving trifluridine/tipiracil at the recommended starting dose (group 1) and nonintegrated data on serious adverse events (SAEs) representing all clinical experience with trifluridine/tipiracil as of the data cutoff date (group 3) are also summarized. In group 2, myelosuppressive and all-grade gastrointestinal adverse events (AEs) were more frequent in trifluridine/tipiracil patients than in placebo patients. The trifluridine/tipiracil and placebo patients had similar frequencies of AEs leading to discontinuation (9.0 vs. 11.5%) and SAEs (27.7 vs. 29.2%); fatal AEs were more frequent in placebo patients than in trifluridine/tipiracil patients (9.3 vs. 2.8%). AEs leading to interruptions/delays/reductions were more frequent in trifluridine/tipiracil patients (56.3 vs. 12.7%). Trifluridine/tipiracil was generally well tolerated, but over 50% of patients required interruptions/delays/reductions. There was a low rate of discontinuations, SAEs, and fatal AEs. This analysis confirms the safety profile observed in RECOURSE.

AB - SAHA, a member of histone deacetylase inhibitors (HDACIs), which emerged as a class of novel antitumor drug, has been used in clinical treatment of cancers. However, clinical experience of SAHA in solid tumors has been disappointing. Nevertheless, the underlying mechanism of this deficiency is not clearly understood. In the present study, we found that SAHA could induce epithelial mesenchymal transitions (EMT) in lung cancer A549 cells, which was associated with increased migration capability and cellular morphology changes. We showed that SAHA decreased epithelial marker E-cadherin's expression and increased the expression of mesenchymal marker vimentin. SAHA upregulated the protein and mRNA expression of transcription factor Slug in a time-dependent manner and promoted its nuclear translocation. We further demonstrated that SAHA upregulated Slug expression by promoting Slug acetylation but not influencing the phosphorylation of GSK-3beta, a main kinase-controlled Slug expression. Finally, silencing of Slug by siRNA reversed EMT marker expressions and cellular morphology change induced by SAHA, suggesting that Slug plays a crucial role in SAHA-mediated EMT in A549 cells. Our research study provided a better understanding of treatment failure of SAHA in patients with solid tumors. Therefore, more attention should be paid to cancer treatment using SAHA and strategies for reversing EMT before using SAHA would be better if the value of SAHA in the treatment of solid tumors, especially lung cancer, is realized. PMID- 29176397 TI - A case of heavily pretreated metastatic cardiac angiosarcoma treated successfully using eribulin. AB - Eribulin mesylate (eribulin) is a nontaxane microtubule inhibitor approved in Japan for treating soft tissue sarcoma irrespective of histological subtypes. Thus, our department routinely uses eribulin to treat any histological subtype of sarcoma for patients who have experienced disease progression during standard therapy. However, evidence on the efficacy of eribulin in treating sarcomas that are neither liposarcoma nor leiomyosarcoma is limited. Recently, we encountered a case of a heavily pretreated cardiac angiosarcoma that responded well to eribulin treatment. The patient was a 34-year-old Japanese woman with advanced angiosarcoma, who had been pretreated heavily using several lines of chemotherapy. Eribulin was administered as the eighth line of treatment and the dose was adjusted because of grade 4 neutropenia. After three cycles of treatment, contrast-enhanced computed tomography showed a partial tumor response, which was sustained for ~4 months. This case suggests that eribulin may be a potential therapeutic option for angiosarcoma. Further studies are needed to confirm the benefit of eribulin for patients with angiosarcoma and to establish predictive markers for eribulin sensitivity. PMID- 29176398 TI - The role of the globular heads of the C1q receptor in paclitaxel-induced human ovarian cancer cells apoptosis by a mitochondria-dependent pathway. AB - As a mitochondrial membrane protein, globular C1q receptor (gC1qR) can mediate a variety of biological responses. Our study aims to investigate the role of gC1qR in paclitaxel-induced apoptosis of human ovarian cancer cells and to elucidate its potential molecular mechanism. The level of gC1qR was examined using real time PCR and western blot analyses. Human ovarian cancer cells viability, migration, and proliferation were detected using the water-soluble tetrazolium salt (WST-1) assay, the transwell assay, and H-thymidine incorporation into DNA (H-TdR) assay, respectively. Apoptosis in cells was assessed using flow cytometric analysis. The intracellular reactive oxygen species was estimated by the fluorescence of H2DCFDA and the mitochondrial membrane potential was tested using a JC-1 probe. The expression of the gC1qR gene decreased significantly in human ovarian cancer tissues relative to the surrounding non-neoplastic ovarian tissues. Cells treated with paclitaxel showed increased gC1qR gene expression, cell apoptosis, and mitochondria dysfunction, and the effects on these cells could be abrogated by the addition of gC1qR small-interfering RNA or alpha-lipoic acid that was used to protect the mitochondria function. In summary, these data support a mechanism that gC1qR-induced mitochondria dysfunction was involved in the paclitaxel-mediated apoptosis of ovarian cancer cells.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 29176399 TI - New instrumentations in the operating room for sinus surgery. AB - PURPOSE OF REVIEW: The article reviews the advancements in instrumentation in the operating room that augment the speed, safety or outcomes of endoscopic sinus surgery (ESS). The article aims to update the Rhinologist on recent perioperative instruments that may benefit their practice. RECENT FINDINGS: The greatest advancements in the recent years have been in the field of visualization and optics. The introduction of high definition and ultra high definition 4K camera and screens supported by improvements with three-dimensional and variable angled endoscopes have greatly enhanced the quality and range of the visual information available to the sinus surgeon. This is closely supported by flexibility and enhanced functionality of the powered instrumentation with bipolar, monopolar and malleable blades and ever increasing more powerful burs. SUMMARY: Recent years have seen notable developments in the areas of optics, cameras and powered instruments to support the sinus surgeon. This article summarizes these developments and highlights the major benefits of these developments. PMID- 29176400 TI - Cost-effectiveness analysis of HLA-B*58: 01 genetic testing before initiation of allopurinol therapy to prevent allopurinol-induced Stevens-Johnson syndrome/toxic epidermal necrolysis in a Malaysian population. AB - OBJECTIVE: Studies found a strong association between allopurinol-induced Stevens Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) and the HLA-B*58:01 allele. HLA-B*58:01 screening-guided therapy may mitigate the risk of allopurinol induced SJS/TEN. This study aimed to evaluate the cost-effectiveness of HLA B*58:01 screening before allopurinol therapy initiation compared with the current practice of no screening for Malaysian patients with chronic gout in whom a hypouricemic agent is indicated. METHODS: This cost-effectiveness analysis adopted a societal perspective with a lifetime horizon. A decision tree model coupled with Markov models were developed to estimate the costs and outcomes, represented by quality-adjusted life years (QALYs) gained, of three treatment strategies: (a) current practice (allopurinol initiation without HLA-B*58:01 screening); (b) HLA-B*58:01 screening before allopurinol initiation; and (c) alternative treatment (probenecid) without HLA-B*58:01 screening. The model was populated with data from literature review, meta-analysis, and published government documents. Cost values were adjusted for the year 2016, with costs and health outcomes discounted at 3% per annum. A series of sensitivity analysis including probabilistic sensitivity analysis were carried out to determine the robustness of the findings. RESULTS: Both HLA-B*58:01 screening and probenecid prescribing were dominated by current practice. Compared with current practice, HLA-B*58:01 screening resulted in 0.252 QALYs loss per patient at an additional cost of USD 322, whereas probenecid prescribing resulted in 1.928 QALYs loss per patient at an additional cost of USD 2203. One SJS/TEN case would be avoided for every 556 patients screened. At the cost-effectiveness threshold of USD 8695 per QALY, the probability of current practice being the best choice is 99.9%, in contrast with 0.1 and 0% in HLA-B*58:01 screening and probenecid prescribing, respectively. This is because of the low incidence of allopurinol-induced SJS/TEN in Malaysia and the lower efficacy of probenecid compared with allopurinol in gout control. CONCLUSION: This analysis showed that HLA-B*58:01 genetic testing before allopurinol initiation is unlikely to be a cost-effective intervention in Malaysia. PMID- 29176401 TI - 2017 Military Supplement: Dodecafluoropentane Emulsion (Ddfpe) as a Resuscitation Fluid for Treatment of Hemorrhagic Shock and Traumatic Brain Injury: A Review. AB - Dodecafluoropentane emulsion (DDFPe) is a novel nanotechnology for oxygen delivery with therapeutic potential for hemorrhagic shock and/or traumatic brain injury (TBI). DDFPe demonstrates efficacy at smaller doses than previously tested perfluorocarbon oxygen therapeutics. This smaller dose potentially eliminates toxicities exhibited by previous oxygen therapeutics, while anti-inflammatory properties of DDFPe may alleviate damage from ischemia reperfusion injury. This mini-review summarizes our progress in developing a battle-field ready product to prevent combat death due to hemorrhagic shock and/or TBI. Preclinical studies, for both indications, show promising effects of DDFPe as a resuscitation fluid. DDFPe may become a part of the toolkit for tactical healthcare professionals in battlefield and domestic emergency medicine. PMID- 29176402 TI - Clinical Outcomes of Minimized Hydrocortisone Dosage of 100 Mg/Day on Lower Occurrence of Hyperglycemia in Septic Shock Patients. AB - BACKGROUND: The current international guideline recommended 200 mg/day of hydrocortisone intravenously to treat septic shock. However, a subsequent study on cortisol metabolism actually showed an increase in cortisol level during sepsis. Hence, the smaller hydrocortisone dose of 100 mg/day might be sufficient and reduce steroid-associated complications. We aimed to compare the clinical outcomes of minimized hydrocortisone dose of 100 mg to the currently recommended dose in the treatment of septic shock patients. METHODS: A double-blinded randomized controlled trial included 80 septic shock patients with hemodynamic instability despite fluid and vasopressive therapy. Participants were divided equally into two groups to treat with 100 mg/day or 200 mg/day of hydrocortisone, then stepwise down titrated and discontinued on day 8. The outcome of interest was the hyperglycemic rate. Vital status, time to shock reversal, superinfection and gastrointestinal bleeding rates were also compared. RESULTS: Patients with 100 mg hydrocortisone had significantly lower hyperglycemic rate compared with 200 mg, 63.9% versus 86.5% (the adjusted hazard ratio [HR], 0.08; 95% confidence interval [CI], 0.02-0.41, P = 0.002). Time to shock reversal was shorter in patients with 100 mg hydrocortisone, 2 days vs. 4 days, P = 0.031. The 28-day mortality rate when adjusted for Simplified Acute Physiology Score II showed no significant difference (HR, 0.68; 95% CI, 0.37-1.24, P = 0.209). The reinfection and gastrointestinal bleeding rates were comparable between groups. CONCLUSION: Minimized daily hydrocortisone dosage of 100 mg could lower the occurrence of hyperglycemia without increasing mortality in septic shock, compared with the currently recommended dosage of 200 mg/day. PMID- 29176403 TI - TLR4 and NLRP3 Caspase 1- IL-1beta- Axis are not Involved in Colon Ascendens Stent Peritonitis (Casp)-Associated Heart Disease. AB - Hemodynamic collapse and myocardial dysfunction are among the major causes of death in severe sepsis. The purpose of this study was to assess the role played by TLR4 and by the NLRP3 inflammasome in the cardiac dysfunction that occurs after high-grade polymicrobial sepsis. We performed the colon ascendens stent peritonitis (CASP) surgery in Tlr4, Nlrp3 and caspase-1 mice. We also assessed for the first time the electrical heart function in the CASP model. The QJ interval was increased in wild-type C57BL/6J mice after CASP when compared to sham controls, a result paralleled by an increase in the cardiac action potential duration (APD). The decreases in ejection fraction (EF), left-ventricle end diastolic volume (LVEDV), stroke volume, and cardiac output found after CASP were similar among all groups of mice. Similar heart response was found when Nlrp3 mice were submitted to high-grade CLP. Despite developing cardiac dysfunction similar to wild-types after CASP, Nlrp3 mice had reduced circulating levels of IL 1beta, IL-6 and TNF-alpha. Our results demonstrate that the genetic ablation of Tlr4, Nlrp3, and caspase-1 does not prevent the cardiac dysfunction, despite preventing the increase in pro-inflammatory cytokines, indicating that these are not feasible targets to therapy in high-grade sepsis. PMID- 29176404 TI - Antiplatelet Therapy for Critically Ill Patients: A Pairwise and Bayesian Network Meta-Analysis. AB - Antiplatelet therapy is an attractive treatment option for critically ill patients. However, more evidence on the benefit of this therapy is required. We searched the PubMed and Embase databases from their inception to June 2017 for randomized controlled trials and observational studies that assess the effect of antiplatelet therapy in critically ill patients. Antiplatelet therapy resulted in significant decreases in hospital mortality (risk ratio [RR] 0.81, 95% confidence interval [CI], 0.68-0.97; P = 0. 025), intensive care unit (ICU) mortality (RR 0.78, 95% CI, 0.63-0.97; P = 0. 027), incidence of respiratory distress syndrome or acute lung injury (RR 0.73, 95% CI, 0.58-0.91; P = 0.006), and incidence of sepsis (RR 0.81, 95% CI, 0.68-0.97; P = 0.021). A predefined subgroup analysis according to patient type suggested that hospital mortality and ICU mortality benefits were seen only in septic patients (RR 0.71, 95% CI, 0.58-0.86; P < 0.0001) and (RR 0.65, 95% CI, 0.49-0.86; P = 0.002). By network meta-analysis, the predictive interval plot showed that patients treated with aspirin and clopidogrel had lower risk of hospital mortality as compared with control group. The assessment of rank probabilities using SUCRA plots indicated that aspirin presented the greatest likelihood of having lowest hospital mortality rate. The results of this meta-analysis suggest that antiplatelet therapy is useful for the treatment in critically ill patients, and this is primarily due to an effect on septic patients. Network meta-analysis shows that the probability of being the best antiplatelet therapy for critically ill patients was aspirin. PMID- 29176405 TI - Lipopeptide PAM3CYS4 Synergizes N-Formyl-Met-Leu-Phe (fMLP)-Induced Calcium Transients in Mouse Neutrophils. AB - N-Formyl-Met-Leu-Phe (fMLP), a mimic of N-formyl oligopeptides that are released from bacteria, is a potent leukocyte chemotactic factor. It induces intracellular calcium ([Ca]i) transient that is important for various neutrophil biological functions, e.g., adhesion, ROS, and cytokine productions. Toll-like receptors (TLRs), an essential part of host innate immunity, regulate neutrophil activities, but their role in [Ca]i signaling is less clear. In the present study, we examined the effect of several TLR ligands, including Pam3Cys4 (TLR1/2), lipopolysaccharide (LPS, TLR4), and lipoteichoic acid (LTA, TLR2/6), on calcium signaling and on the fMLP-induced [Ca]i transients in mouse neutrophils loaded with Fura-2/AM. We found that unlike fMLP, the three TLR ligands tested did not elicit any detectable Ca flux. However, Pam3Cys4, but not LPS or LTA, markedly synergized the fMLP-induced [Ca]i transients, and had no effect on the host component keratinocyte-derived cytokine (KC)- or C5a-induced calcium flux. The effect of Pam3Cys4 on the fMLP-induced [Ca]i transients is by enhancing extracellular Ca influx, not intracellular Ca release. Surprisingly, deletion of TLR2 or MyD88 in neutrophils had no impact on the Pam3Cys4's effect, suggesting a TLR2-MyD88-independent mechanism. Finally, using the pan PKC activator and inhibitor, we demonstrated that PKC negatively regulated fMLP-induced [Ca]i transients and that inhibition of PKC did not prohibit Pam3Cys4's synergistic effect on the fMLP-induced calcium influx. In conclusion, the present study identified a novel synergistic effect of Pam3Cys4 on fMLP-induced [Ca]i transients, a process important for many neutrophil biological functions. PMID- 29176406 TI - Walking Aids for Enabling Activity and Participation: A Systematic Review. AB - In this systematic literature review, we examined whether and how walking aids (i.e., canes, crutches, walkers, and rollators) enable activity and participation among adults with physical disabilities. Medline, Embase, all EBM reviews, PsychInfo, CINAHL, and Web of Science databases were used to identify studies published since 2008. Quantitative and qualitative designs were included. Data regarding participants, assistive device use, outcome measures, and domains of participation were extracted. Two reviewers independently rated the level of evidence and methodological quality of the studies. Outcomes were categorized per types of walking aids and activity and participation domains. Thirteen studies were included. Two studies involved canes, four pertained to rollators, and seven dealt with multiple types of walking aids. Mobility was the most frequently examined domain of activity and participation. Both negative and positive results were found. Negative outcomes were linked to the physical characteristics of the device, the use, environment, and personal reluctance. When incorporated in daily life, walking aids were found to enable several domains of activity and participation. Whether walking aids facilitate activity and participation may depend on the user's ability to overcome obstacles and integrate them in daily life. More high-quality research is needed to draw conclusions about their effectiveness. PMID- 29176407 TI - Cholesterol metabolism in humans: a review of methods and comparison of results. AB - PURPOSE OF REVIEW: Cholesterol metabolism has been the object of intense investigation for decades. This review focuses on classical and novel methods assessing in vivo cholesterol metabolism in humans. Two factors have fueled cholesterol metabolism studies in the last few years: the renewed interest in the study of reverse cholesterol transport (RCT) as an atheroprotective mechanism and the importance of the gut microbiome in affecting cholesterol metabolism. RECENT FINDINGS: Recent applications of these methods have spanned from the assessment of the effect on cholesterol synthesis, absorption or excretion of drugs (such as ezetimibe, PCSK9 inhibitors and plant sterols) and the gut microbiome to the more complex assessment of transintestinal cholesterol excretion (TICE) and RCT. SUMMARY: These methods continue to be a valuable tool to answer novel questions and investigate the complexity of in-vivo cholesterol metabolism. PMID- 29176408 TI - Prescription Opioid Use among Opioid-Naive Women Undergoing Immediate Breast Reconstruction. AB - BACKGROUND: Cancer patients may be particularly vulnerable to the deleterious effects of prolonged opioid use. The authors explored the factors that influence postoperative opioid prescription fills among women following postmastectomy reconstruction. METHODS: Using the Truven Health MarketScan Research Databases, the authors identified a cohort of 4113 opioid-naive patients undergoing mastectomy and immediate breast reconstruction between January of 2010 and August of 2014. Outcomes included average daily oral morphine equivalents and the incidence of prolonged opioid fills (between 90 and 120 days after surgery). Using multivariable regression, the authors examined the effect of patient demographic characteristics, reconstructive technique, comorbid medical and psychiatric conditions, and postoperative complications on outcome variables. RESULTS: In this cohort, 90 percent of patients filled opioid prescriptions perioperatively, and 10 percent continued to fill prescriptions beyond 3 months after surgery. Patients with depression were more likely to fill prescriptions of higher average daily oral morphine equivalents (74.2 mg versus 58.3 mg; p < 0.01), and patients with anxiety were more likely to fill opioids for prolonged periods (13.4 percent versus 9.1 percent; p < 0.01). Patients undergoing autologous free flap reconstruction were less likely to fill prescriptions for a prolonged period following surgery (5.9 percent versus 10.2 percent; p < 0.001). CONCLUSIONS: Prescription opioid fills are common following breast reconstruction, and 10 percent of all patients continue to fill opioid prescriptions beyond 3 months after surgery. Prolonged fills are influenced by both patient factors and surgical procedure, and attention should be directed toward identifying opioid alternatives when possible.

PMID- 29176410 TI - The Impact of Autologous Breast Reconstruction on Body Mass Index Patterns in Breast Cancer Patients: A Propensity-Matched Analysis. AB - BACKGROUND: Weight gain is common in breast cancer patients and increases the risk of recurrence and mortality. The authors assessed the impact of autologous breast reconstruction on body mass index patterns after diagnosis in mastectomy patients. METHODS: Women undergoing therapeutic mastectomy at the authors' institution from 2008 to 2010 were identified. Patients undergoing no breast reconstruction or autologous breast reconstruction were propensity-matched by age at diagnosis, baseline obesity, mastectomy laterality, and adjuvant therapies. Multivariable regression was used to estimate covariate associations with percentage body mass index change and percentage body mass index change greater than 5.0 percent at 1 to 4 years after diagnosis. RESULTS: Of 524 total patients, 80 propensity-matched pairs were identified. In multivariable regression, women undergoing immediate autologous breast reconstruction had reduced body mass index changes after diagnosis, compared with nonreconstruction patients, at 1 year (beta = -5.25 percent; p < 0.01), 2 years (beta = -8.78 percent; p < 0.01), and 3 years (beta = -7.21 percent; p < 0.01). After 4 years, all autologous reconstruction was predictive of reduced body mass index changes (beta = -3.54 percent; p = 0.02). Higher body mass index increases were observed among women who were leaner at diagnosis (p < 0.01 at 1 year) and received chemotherapy (p = 0.02 at 3 years; p = 0.04 at 4 years). CONCLUSIONS: Women undergoing autologous breast reconstruction gained less weight after diagnosis than nonreconstruction patients. Normal baseline body mass index and chemotherapy were predictive of greater body mass index increases. These findings may guide targeted weight management strategies in high-risk patients to maximize survival rates. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III. PMID- 29176411 TI - Evidence-Based Performance Measures: Quality Metrics for the Care of Patients Undergoing Breast Reconstruction. AB - The American Society of Plastic Surgeons commissioned the Breast Reconstruction Performance Measure Development Work Group to identify and draft quality measures for the care of patients undergoing breast reconstruction surgery. Two outcome measures were identified. The first desired outcome was to reduce the number of returns to the operating room following reconstruction within 60 days of the initial reconstructive procedure. The second desired outcome was to reduce flap loss within 30 days of the initial reconstructive procedure. All measures in this report were approved by the American Society of Plastic Surgeons Breast Reconstruction Performance Measures Work Group and the American Society of Plastic Surgeons Executive Committee. The Work Group recommends the use of these measures for quality initiatives, Continuing Medical Education, Maintenance of Certification, American Society of Plastic Surgeons' Qualified Clinical Data Registry reporting, and national quality reporting programs. PMID- 29176412 TI - Prospective Controlled Study of Chin Augmentation by Means of Fat Grafting. AB - BACKGROUND: Although fat grafting is a valuable tool for different areas of plastic surgery, its use in the chin area has never been evaluated. A variety of methods are available for adjusting suboptimal chin morphology, and they each present drawbacks. METHODS: A prospective controlled study was performed to evaluate whether fat grafting increases the chin volume and sagittal projection and to determine the magnitude and nature of the observed changes. Forty-two consecutive patients underwent chin augmentation by means of fat grafting between October of 2014 and January of 2016. All patient images were analyzed using a software program (Fiji package of ImageJ), which creates a three-dimensional version of the chin that is used to produce reliable estimates of the volume and gain in sagittal projection. RESULTS: All 42 patients showed an increase in the sagittal projection and total volume at 4 weeks and 6 months after surgery. The sagittal projection increased from 4 mm to 12 mm (average, 8.9 mm) and from 3 mm to 11 mm (average, 7 mm) after 4 weeks and 6 months, respectively. The total volume increase ranged from 3 to 11 ml (average, 8 ml) after 4 weeks and from 3 to 8 ml (average, 7.4 ml) after 6 months. CONCLUSION: Fat grafting to the chin area is a reliable method for improving chin volumes (to a maximum of approximately 10 cc in our study) and sagittal projections (to a maximum of approximately 11 mm in our study). CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV. PMID- 29176413 TI - Mentor Contour Profile Gel Implants: Clinical Outcomes at 10 Years. AB - BACKGROUND: Contour Profile Gel/MemoryShape breast implants consist of a textured silicone elastomer shell filled with silicone gel. The objective of this clinical study was to assess the safety and effectiveness of Contour Profile Gel/MemoryShape breast implants in women who were undergoing primary breast augmentation, primary breast reconstruction, or revision surgery (revision augmentation or revision-reconstruction). METHODS: This was a prospective, open label, multicenter clinical study involving Contour Profile Gel/MemoryShape breast implants in 955 female subjects, including 572 primary augmentation, 124 revision-augmentation, 190 primary reconstruction, and 69 revision-reconstruction subjects. Safety was assessed based on the incidence, severity, and method of resolution of all complications. Endpoints were examined on both a per-subject and a per-implant basis. RESULTS: For the primary augmentation, revision augmentation, primary reconstruction, and revision-reconstruction cohorts, the Kaplan-Meier estimated 10-year cumulative incidence rates for the key complications at the subject level were as follows: Baker grade III/IV capsular contracture, 3.6 (primary augmentation), 15.5 (revision-augmentation), 14.3 (primary reconstruction), and 16.4 (revision-reconstruction) percent; infection, 0.7 (primary augmentation), 1.9 (revision-augmentation), 1.6 (primary reconstruction), and 2.9 (revision-reconstruction) percent; explantation with or without replacement, 9.2 (primary augmentation), 25.9 (revision-augmentation), 34.1 (primary reconstruction), and 49.0 (revision-reconstruction) percent; explantation with replacement with study device, 4.0 (primary augmentation), 10.8 (revision-augmentation), 16.7 (primary reconstruction), and 27.9 (revision reconstruction) percent; and any reoperation, 22.3 (primary augmentation), 35.0 (revision-augmentation), 52.7 (primary reconstruction), and 59.7 (revision reconstruction) percent. CONCLUSION: The results of this study demonstrate that Contour Profile Gel/MemoryShape breast implants are safe and effective for primary and revision breast augmentation and reconstruction for women at least 22 years old. PMID- 29176414 TI - Prospective, Double-Blind Evaluation of Umbilicoplasty Techniques Using Conventional and Crowdsourcing Methods. AB - BACKGROUND: Umbilical reconstruction is an important component of deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study evaluated the aesthetics of three different umbilical reconstruction techniques during DIEP flap breast reconstruction. METHODS: From January to April of 2013, a total of 29 consecutive patients undergoing DIEP flap breast reconstruction were randomized intraoperatively to receive one of three umbilicoplasty types: a diamond, an oval, or an inverted V incision. Independent plastic surgeons and members of the general public, identified using an online "crowdsourcing" platform, evaluated aesthetic outcomes in a blinded fashion. Reviewers were shown postoperative photographs of the umbilicus of all patients and a four-point Likert scale was used to rate the new umbilicus on the size, scar formation, shape, localization, and overall appearance. RESULTS: Results for the focus group of independent plastic surgeons and 377 members of the public were retrieved (n = 391). A total of 10 patients (34.5 percent) were randomized into having the diamond incision, 10 (34.5 percent) had the oval incision, and nine (31.0 percent) had the inverted V incision. Patients were well matched in terms of overall characteristics. The general public demonstrated a significant preference for the oval incision in all five parameters. There was no preference identified among surgeons. CONCLUSION: This study provides evidence that a sample of the U.S. general public prefers the aesthetics of the oval umbilicoplasty incision, which contrasted with the lack of preference identified within this focus group of plastic surgeons. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II. PMID- 29176415 TI - Discussion: Protective Effect of Hydrogen Gas Inhalation on Muscular Damage Using a Mouse Hindlimb Ischemia-Reperfusion Injury Model. PMID- 29176416 TI - Is Postoperative Intensive Care Unit Care Necessary following Cranial Vault Remodeling for Sagittal Synostosis? AB - BACKGROUND: Of U.S. craniofacial and neurosurgeons, 94 percent routinely admit patients to the intensive care unit following cranial vault remodeling for correction of sagittal synostosis. This study aims to examine the outcomes and cost of direct ward admission following primary cranial vault remodeling for sagittal synostosis. METHODS: An institutional review board-approved retrospective review was undertaken of the records of all patients who underwent primary cranial vault remodeling for isolated sagittal craniosynostosis from 2009 to 2015 at a single pediatric hospital. Patient demographics, perioperative course, and outcomes were recorded. RESULTS: One hundred ten patients met inclusion criteria with absence of other major medical problems. Average age at operation was 6.7 months, with a mean follow-up of 19.8 months. Ninety-eight patients (89 percent) were admitted to a general ward for postoperative care, whereas the remaining 12 (11 percent) were admitted to the intensive care unit for preoperative or perioperative concerns. Among ward-admitted patients, there were four (3.6 percent) minor complications; however, there were no major adverse events, with none necessitating intensive care unit transfers from the ward and no mortalities. Average hospital stay was 3.7 days. The institution's financial difference in cost of intensive care unit stay versus ward bed was $5520 on average per bed per day. Omitting just one intensive care unit postoperative day stay for this patient cohort would reduce projected health care costs by a total of $540,960 for the study period. CONCLUSION: Despite the common practice of postoperative admission to the intensive care unit following cranial vault remodeling for sagittal craniosynostosis, the authors suggest that postoperative care be considered on an individual basis, with only a small percentage requiring a higher level of care.

PMID- 29176419 TI - The Role of Checklists and Human Factors for Improved Patient Safety in Plastic Surgery. AB - LEARNING OBJECTIVES: After studying the article, participants should be able to: 1. Describe the role of human factors and nontechnical skills for patient safety and recognize the need for customization of surgical checklists. 2. Apply encouragement to speaking up and understand the importance of patient involvement for patient safety. 3. Recognize the potential for improvement regarding patient safety in their own environment and take a leading role in the patient safety process. 4. Assess their own safety status and develop measures to avoid unnecessary distraction in the operating room. SUMMARY: Over the past 20 years, there has been increased attention to improving all aspects of patient safety and, in particular, the important role of checklists and human factors. This article gives a condensed overview of selected aspects of patient safety and aims to raise the awareness of the reader and encourage further study of referenced literature, with the goal of increased knowledge and use of proven safety methods. The CME questions should help indicate where there is still potential for improvement in patient safety, namely, in the field of nontechnical skills. PMID- 29176420 TI - Trends and Predictors of National Institutes of Health Funding to Plastic Surgery Residency Programs. AB - BACKGROUND: Recent studies have demonstrated low levels of National Institutes of Health funding for surgical research. The authors compared the funding in plastic surgery with the funding for other surgical specialties. METHODS: A query of National Institutes of Health grants awarded to departments of surgical specialties was performed using the National Institutes of Health RePORTER database (2008 to 2016). Trends in funding were compared by specialty and adjusted for the number of active physicians in each specialty. Plastic surgery residency program characteristics were correlated with funding procurement. RESULTS: Eight hundred eighty-nine faculty at 94 plastic surgery residency programs were queried. Forty-eight investigators (5.4 percent) at 23 programs (24.4 percent) had National Institutes of Health funding. From 2008 to 2016, a total of $84,142,138 was awarded through 81 grants. Funding supported translational (44.6 percent), clinical (26.4 percent), basic science (27.2 percent), and educational (1.7 percent) research. In 2016, plastic surgery received the least amount of National Institutes of Health funding per active physician ($1,530) relative to orthopedic surgery ($3124), obstetrics and gynecology ($3885), urology ($5943), otolaryngology ($9999), general surgery ($11,649), ophthalmology ($11,933), and neurologic surgery ($20,874). Plastic surgery residency program characteristics associated with National Institutes of Health funding were high ranking and had more than 10 clinical faculty (p < 0.05). CONCLUSIONS: Plastic surgery receives the least National Institutes of Health funding among the surgical specialties. Departments and divisions of plastic surgery should support investigators applying for research grants to increase future National Institutes of Health funding.

PMID- 29176428 TI - Heterogeneity assessment in gastroenterology systematic reviews: an analysis of current practices. AB - AIM: In systematic reviews and meta-analyses, variation (heterogeneity) in the primary studies is often a concern resulting from factors such as study design, data analysis methods, study quality, settings and interventions and/or patient characteristics. After determining the extent of heterogeneity, authors examine the causes of heterogeneity via sensitivity analysis, subgroup analysis and/or meta-regression analysis. There is no assessment of heterogeneity practices in gastroenterological literature; thus, we present this assessment. METHODS: We performed a PubMed search to identify systematic reviews published from 2011 to 2016 in the top 10 gastroenterology journals, as well as gastrointestinal topics in general medical journals and the PROSPERO trial registry. The first and second authors independently abstracted data elements, such as levels of inconsistency, sensitivity analysis, subgroup analysis and meta-regression analysis. RESULTS: The search identified 3154 studies; of these, 337 were eligible for inclusion. Included studies consisted of 306 from the gastroenterology literature, 19 studies from PROSPERO and 12 studies from the general internal medicine journals. A significant number of reviews in gastroenterology journals (31.05%, 95/306), internal medicine journals (16.67%, 2/12) and PROSPERO (52.63%, 10/19) conducted a meta-analysis despite having fewer than 10 primary studies. Most of the reviews in gastroenterology journals (81.05%, 248/306), general internal medicine journals (75%, 9/12) and PROSPERO results (73.68%, 14/19) used a combination of methods to assess heterogeneity. There were 20 various definitions of levels of inconsistency (I) throughout all the results. Random effects was the most common model choice in gastroenterology journals reviews (57.84%; 177/306), internal medicine journals (75%, 9/12) and for PROSPERO results (41.11%, 8/19). The majority of reviews did not discuss the impact of heterogeneity on results in the gastroenterology journals (62.09%, 190/306), only one study in the general internal medicine journals and only one study in the PROSPERO results. CONCLUSION: In gastroenterology journals and other journals printing gastrointestinal topic systematic reviews, most conducted statistical tests for heterogeneity; however, the statistical methods could be more robust and the impact of heterogeneity discussed more often in the article. PMID- 29176429 TI - Identifying and classifying indicators affected by performing clinical pathways in hospitals: a scoping review. AB - AIM: To analyse the evidence regarding indicators affected by clinical pathways (CPW) in hospitals and offer suggestions for conducting comprehensive systematic reviews. METHODS: We conducted a systematic scoping review and searched the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, Scopus, OVID, Science Direct, ProQuest, EMBASE and PubMed. We also reviewed the reference lists of included studies. The criteria for inclusion of studies included experimental and quasi-experimental studies, implementing CPW in secondary and tertiary hospitals and investigating at least one indicator. Quality of included studies was assessed by two authors independently using the Critical Appraisal Skills Program for clinical trials and cohort studies and the Joanna Briggs Institute Critical Appraisal Tool for Quasi-Experimental Studies. RESULTS: Forty seven out of 2191 studies met the eligibility and inclusion criteria. The majority of included studies had pretest-posttest quasi-experimental design and had been done in developed countries, especially the United States. The investigation of evidence resulted in identifying 62 indicators which were classified into three categories: input indicators, process and output indicators and outcome indicators. Outcome indicators were more frequent than other indicators. Complication rate, hospital costs and length of hospital stay were dominant in their own category. Indicators such as quality of life and adherence to guidelines have been considered in studies that were done in recent years. CONCLUSION: Implementing CPW can affect different types of indicators such as input, process, output and outcome indicators, although outcome indicators capture more attention than other indicators. Patient-related indicators were dominant outcome indicators, whereas professional indicators and organizational factors were considered less extensively. WHAT IS KNOWN ABOUT THE TOPIC?: WHAT DOES THIS ARTICLE ADD? PMID- 29176430 TI - The role of N-methyl-D-aspartate receptors and metabotropic glutamate receptor 5 in the prepulse inhibition paradigms for studying schizophrenia: pharmacology, neurodevelopment, and genetics. AB - Treatments for the positive and negative symptoms of schizophrenia have been explored for decades, but no completely successful therapy has been found as yet. Metabotropic glutamate receptor 5 (mGluR5), which potentiates N-methyl-D aspartate receptors in brain regions implicated in schizophrenia, has become a novel drug target in the treatment of schizophrenia, especially for the mGluR5 positive allosteric modulators. Individuals with schizophrenia show deficits in prepulse inhibition (PPI), which is an operational measurement of sensorimotor gating. In this review, we focus on pharmacological, neurodevelopmental, and genetic animal models of disrupted PPI, with the aim of showing the potential role of mGluR5 in modulating the activity of N-methyl-D-aspartate receptors and their contributions toward the treatment of schizophrenia. As, the impairment of attentional modulation of PPI, but not that of baseline PPI, in individuals with schizophrenia is correlated with their symptom severity, this review also highlights that investigation of attentional modulation of PPI is critical for studying both cognitive impairments and glutamatergic dysfunctions of schizophrenia.

AB - PURPOSE OF REVIEW: Gnotobiotic models have the potential to provide substantial insight into how the microbiome shapes its host's response to vaccines. This review aims to summarize literature about the role of the microbiome in shaping the immune system and vaccine response heterogeneity, summarize gnotobiotic and other murine models that help us understand the immune system and vaccine response, and suggest novel ways that these models could be used to further understand vaccine response heterogeneity. RECENT FINDINGS: Clinical data have suggested that numerous vaccines' effectiveness are regulated by the microbiome and often correlate with the abundance of specific taxa. Gnotobiotic and other animal models are beginning to illuminate the complex effects induced by the presence of particular microbial groups and communities. Such models have identified microbial groups that improve vaccine response to rotavirus vaccine and identified pathways by which the microbiome influences response to influenza and other vaccines. SUMMARY: By applying a range of vaccines across gnotobiotic mouse models, researchers may be able to identify the effects of single microorganisms as well as interacting communities of microorganisms on the immune response.

Timely urinary catheter removal was significantly greater in hospitals with more licensed nursing hours per patient day. PMID- 29176443 TI - Levosimendan enhances memory through antioxidant effect in rat model: behavioral and molecular study. AB - Impairment of learning and memory has been associated with accumulation of reactive oxygen species in the body. It has also been found that antioxidants enhance learning and memory. Levosimendan is a cardiac inotropic and vasodilator agent that has pleotropic effects including antioxidant, anti-inflammatory, and smooth muscle vasodilatory actions. In this study, we investigated the effect of levosimendan on learning and memory in rats. Levosimendan (12 ug/kg, intraperitoneally) or vehicle was administered once a week for 8 weeks. The radial arm water maze was used to assess spatial learning and memory. In addition, hippocampus levels of antioxidant biomarkers/enzyme - reduced glutathione (GSH), oxidized glutathione (GSSG), GSH/GSSG ratio, glutathione peroxidase, superoxide dismutase, catalase, and thiobarbituric acid reactive substance - were assessed. Levosimendan significantly enhanced short-term (30 min) and long-term (5 h) memory. Levosimendan also significantly increased levels of glutathione peroxidase and GSH and decreased thiobarbituric acid reactive substance. There were no significant effects on the level of other oxidative stress biomarkers. In conclusion, levosimendan enhanced short-term and long-term memory by potentiating antioxidant defense mechanism in the hippocampus.

PMID- 29176445 TI - New thinking on gonorrhoea control in MSM: are antiseptic mouthwashes the answer? AB - PURPOSE OF REVIEW: The rate of gonorrhoea is rising and is much higher in men who have sex with men (MSM) than heterosexuals. The purpose of this review was to describe research supporting a new paradigm of transmission of gonorrhoea in MSM and interventions that may result from this. RECENT FINDINGS: Evidence is accumulating that gonorrhoea in MSM is transmitted differently than previously thought and that asymptomatic sites of infection may play a major role in the persistent of gonorrhoea at a population level. Saliva commonly contains gonorrhoea, and saliva is commonly used during sexual acts. Both in-vitro, in vivo studies have suggested that antibacterial mouthwash may reduce gonorrhoea at the oropharynx. A recently published mathematical model also suggests that if mouthwash were effective, it would result in considerable declines in the community prevalence in MSM. SUMMARY: A newly suggested paradigm for the transmission of gonorrhoea in MSM could potentially offer a simple condom-free control strategy. But considerable more research is required before it could be recommended even if it were shown to be effective in a clinical trial. PMID- 29176446 TI - Addressing unhealthy alcohol use among people living with HIV: recent advances and research directions. AB - PURPOSE OF REVIEW: Unhealthy alcohol use is prevalent among people living with HIV (PLWH). We sought to identify the most current literature examining the impact of unhealthy alcohol on health outcomes and latest developments on how to best intervene. RECENT FINDINGS: New research shows that PLWH have heightened morbidity and mortality at lower levels of alcohol consumption compared with HIV uninfected persons. Studies published since 2016 have further elucidated the effects of persistent unhealthy alcohol use on HIV treatment outcomes over time. Screening and brief interventions, as well as pharmacologic treatment, can reduce unhealthy alcohol use among PLWH. SUMMARY: Unhealthy alcohol use is an important and modifiable risk factor for poor health and HIV treatment outcomes among PLWH. More research is needed to encourage and maintain engagement in alcohol-related interventions and improve implementation. PMID- 29176447 TI - Pattern of Methamphetamine Use and the Time Lag to Methamphetamine Dependence. AB - OBJECTIVES: Use of methamphetamine (MA) commonly co-occurs with the use of other substances. The present study aims to examine substance initiation patterns of other substances, including alcohol, nicotine, inhalants, and cannabis (OTH), in MA users and its consequence on the time lag of MA dependence. METHODS: Sociodemographic, environmental, and clinical data were obtained from MA users at a Thai substance treatment center. The Semi-Structured Assessment for Drug Dependence and Alcoholism was employed to diagnose drug dependence. RESULTS: Of 991 MA users, 52.6% were males, and the average age was 26.8 +/- 7.1 years. The mean age of first MA use (18 years) was greater than the mean age of first use of alcohol (17 years), nicotine (16 years), and inhalants (15 years) (P < 0.001), but was comparable with the mean age at the first use of cannabis (P > 0.05). Family history of MA use and nicotine dependence were associated with early MA onset. Participants who used MA as their first drug (MA>OTH) were more likely to be female and less likely to smoke intensely and to be exposed to severe traumatic events than those who used MA later than other substances (OTH>MA). The time lag from age at onset of MA use to MA dependence was shorter in OTH>MA than in MA>OTH (3 vs 5 years; chi = 5.7, P = 0.02, log-rank test). CONCLUSIONS: A higher proportion of women was observed in MA>OTH than in OTH>MA. The use of other substances before MA increases the individual's vulnerability in shortening the interval between age at onset of MA use and MA dependence in a substance treatment cohort. PMID- 29176448 TI - Patients' Experiences of Using a Cellular Photo Digital Breathalyzer for Treatment Purposes. AB - OBJECTIVES: The field of eHealth systems is rapidly developing and is now expanding into alcohol treatment settings. Despite a growing public and professional interest, cellular photo digital breathalyzers (CPDBs) have not been investigated in a clinical context so far. In this study, we aimed to investigate the experiences of patients in alcohol treatment who had been using a CPDB TripleA- for a minimum of three months. What are their personal experiences of using the CPDB? Do the patients think it supports them to change their drinking habits, and if so, in what way? METHODS: A qualitative interview study with individuals who had been using the CPDB TripleA, for at least 3 months as complement to treatment (12-step program or hospital-based outpatient care). A thematic analysis with an inductive approach was used to identify, analyze, and interpret patterns within data. RESULTS: In all, 12 interviews were conducted with 8 men and 4 women. Participants were generally enthusiastic about the CPDB and found it convenient and useful, even though it created a need for privacy when using the device. Although technical problems were substantial, participants were tolerant to those. The system was perceived to support self-control and to restore relations, but did not replace the need for close contact with caregivers. Self-motivation to change drinking habits was essential, and could not be reached by solely using the CPDB. CONCLUSIONS: Participants perceived the CPDB as a convenient and useful tool that was supportive under the circumstances that it was used in a context that included personal contact with a caregiver; and the user felt more than just a minimum of motivation to reduce drinking. Technical stability needs to be achieved to secure long-term use. PMID- 29176449 TI - Can Appropriate Systemic Treatment Help Protect the Cornea in Patients With Rheumatoid Arthritis? A Multidisciplinary Approach to Autoimmune Ocular Involvement. AB - PURPOSE: To correlate rheumatologic with ophthalmic and laboratory findings in patients with rheumatoid arthritis (RA) to identify what effect these have on development of ocular disease. METHODS: This is a cross-sectional study of 172 eyes of 86 patients with RA. Patients were examined by a group of rheumatologists. Sociodemographic, clinical, and laboratory data were collected. All patients underwent complete ophthalmologic examination including corneal topography and endothelial cell count. RESULTS: There was no significant correlation between RA-negative prognostic indicators (NPIs) and pathologic corneal findings. Patients using disease-modifying antirheumatic drugs (DMARDs) and antimalarial drugs had greater corneal volumes (mean difference 8.51 mm, 90% confidence interval [CI], 3.98-13.04, P = 0.004; and 2.24, 90% CI, 0.32-4.54, P = 0.048, respectively). Patients using azathioprine had lower endothelial cell counts compared with those using other drugs (mean difference 180 cells/mm, 90% CI, 69-291, P = 0.008). Patients using biologic DMARDs had better tear osmolarity values (between 280 and 300 mOsm/L) than patients not using them (mean difference 14.3 mOsm/L, P = 0.022). There was no correlation between NPIs of RA and positive keratoconus screening indices (Spearman correlation OD -0.013, P = 0.91; OS 0.033, P = 0.76). CONCLUSIONS: There was no clear correlation between RA-NPIs and pathologic corneal findings in our study. DMARDs treatment may help maintain corneal integrity in our patients and prevented collagenolytic manifestations of RA. Other medications such as azathioprine should be used carefully, as endothelial damage may potentially occur. PMID- 29176450 TI - Corneal Cross-Linking With Verteporfin and Nonthermal Laser Therapy. AB - PURPOSE: To test whether verteporfin with a nonthermal laser increases corneal mechanical stiffness and resistance to enzymatic degradation ex vivo. METHODS: Thirty human corneas (n = 5 per group) were treated with verteporfin alone (V), irradiated with nonthermal laser therapy (689 nm) alone (NTL), or received combined treatment of verteporfin with nonthermal laser therapy for 1 sequence (V+NTL1) or 6 sequences (V+NTL6) of 1 minute of NTL exposure. Positive controls were pretreated with 0.1% riboflavin/20% dextran every 3 to 5 minutes for 30 minutes and irradiated with ultraviolet light type A (lambda = 370 nm, irradiance = 3 mW/cm) for 30 minutes using the Dresden protocol (R+UVA). Untreated corneas were used as negative controls. The corneal biomechanical properties were measured with enzymatic digestion, compression, creep, and tensile strength testing. RESULTS: V+NTL6- and R+UVA-treated corneas acquired higher rigidity and more pronounced curvature than untreated corneas. The stress-strain tests showed that V+NTL6 and R+UVA corneas became significantly stiffer than controls (P < 0.005). The V+NTL6 group seemed to be slightly stiffer than the R+UVA group, although the differences were not statistically significant. V+NTL6 corneas were found to have a significantly lower absolute creep rate (-1.87 vs. -3.46, P < 0.05) and significantly higher maximum stress values (7.67 vs. 3.02 P < 0.05) compared with untreated corneas. CONCLUSIONS: Verteporfin-NTL (V+NTL6) increases corneal mechanical stiffness and resistance to enzymatic collagenase degradation. Although a clinical study is needed, our results suggest that V+NTL6 induces corneal cross-linking and corneal biomechanical changes that are similar to those induced by standard corneal collagen cross-linking. PMID- 29176451 TI - Comparison of Pterygium Recurrence Rates Among Different Races and Ethnicities After Primary Pterygium Excision by Surgeons in Training. AB - PURPOSE: To evaluate the impact of race and ethnicity, surgical technique, and level of surgeon training on recurrence rates after primary pterygium excision. METHODS: A retrospective review of patients who underwent primary pterygium excision at our academic institution was performed. The surgical technique conjunctival autografting (CAG) or amniotic membrane grafting (AMG)-was chosen at the attending surgeon's discretion, and all surgeries were performed by surgeons in training. The primary outcome measure was pterygium recurrence, defined as regrowth of fibrovascular tissue onto a clear cornea in the region of previous pterygium removal. RESULTS: There was a significant difference in age at presentation between white (64.3 +/- 11.4), Hispanic (50.0 +/- 13.5), black (64.8 +/- 14.5), and Asian (59.3 +/- 9.2) patients (P < 0.001). Average time to recurrence was 4.4 +/- 3.0 months and was similar between races (P = 0.98). There was a significant difference in recurrence rates between the white (13%), Hispanic (28%), black (33%), and Asian (0%) patients (P = 0.049). Over 12 months, a significant difference in cumulative proportion with recurrence after AMG versus CAG was observed in Hispanic (75% vs. 30%; P = 0.002) and black (100% vs. 42%; P = 0.001) patients. Sex, method of graft fixation (glue, suture, or both), and level of surgeon training showed no difference in pterygium recurrence (P > 0.05). CONCLUSIONS: Hispanic and black patients are more likely to experience pterygium recurrence after AMG than CAG. White patients are less likely than Hispanic or black patients to experience recurrence regardless of the surgical technique. To reduce the likelihood of recurrence, surgeons may consider race and ethnicity when selecting their operative technique. PMID- 29176452 TI - Collagen-Based Fillers as Alternatives to Cyanoacrylate Glue for the Sealing of Large Corneal Perforations. AB - PURPOSE: To describe the use of collagen-based alternatives to cyanoacrylate glue for the sealing of acute corneal perforations. METHODS: A collagen analog comprising a collagen-like peptide conjugated to polyethylene glycol (CLP-PEG) and its chemical crosslinker were tested for biocompatibility. These CLP-PEG hydrogels, which are designed to act as a framework for corneal tissue regeneration, were then tested as potential fillers in ex vivo human corneas with surgically created full-thickness perforations. Bursting pressures were measured in each of 3 methods (n = 10 for each condition) of applying a seal: 1) cyanoacrylate glue with a polyethylene patch applied ab externo (gold standard); 2) a 100-MUm thick collagen hydrogel patch applied ab interno, and 3) the same collagen hydrogel patch applied ab interno supplemented with CLP-PEG hydrogel molded in situ to fill the remaining corneal stromal defect. RESULTS: Cyanoacrylate gluing achieved a mean bursting pressure of 325.9 mm Hg, significantly higher than the ab interno patch alone (46.3 mm Hg) and the ab interno patch with the CLP-PEG filler (86.6 mm Hg). All experimental perforations were sealed effectively using 100 MUm hydrogel sheets as an ab interno patch, whereas conventional ab externo patching with cyanoacrylate glue failed to provide a seal in 30% (3/10) cases. CONCLUSIONS: An ab interno patch system using CLP-PEG hydrogels designed to promote corneal tissue regeneration may be a viable alternative to conventional cyanoacrylate glue patching for the treatment of corneal perforation. Further experimentation and material refinement is required in advance of clinical trials. PMID- 29176453 TI - Role of Confocal Microscopy in the Diagnosis of Pythium insidiosum Keratitis. AB - PURPOSE: To investigate the role of in vivo confocal microscopy for detection of Pythium insidiosum keratitis. METHODS: Medical records and confocal microscopy findings of 20 patients (21 eyes) with culture- or polymerase chain reaction proven P. insidiosum keratitis diagnosed at the Khon Kaen University Eye Center from January 2009 to December 2015 were retrospectively reviewed. Confocal microscopy was performed using Nidek ConfoScan 4. The images from 21 eyes with P. insidiosum keratitis and 4 other fungal keratitides were analyzed visually for morphology of the hyphae and special characteristics that would enable physicians to distinguish P. insidiosum keratitis from other fungal keratitides. RESULTS: A total of 21 eyes of 20 patients were included in the study. Fourteen (70%) were men, and 6 (30%) were women. In vivo confocal microscopy was able to identify hyphae in 20 of 21 eyes (95%). Beaded string-like hyperreflective branching structures with mean branching angles at 78.6 degrees or thin hyperreflective long lines were found in confocal microscopy findings of P. insidiosum keratitis. The diameter of the hyphae varied from 1.5 to 7.5 MUm. CONCLUSIONS: P. insidiosum keratitis is a severe progressive infectious corneal disease that causes vision loss in most patients. Confocal microscopy may provide rapid in vivo visualization of P. insidiosum hyphae in corneal tissues, but it cannot distinguish P. insidiosum from other fungal keratitides. Culture identification with zoospore induction or polymerase chain reaction remains the most reliable means to confirm the diagnosis of P. insidiosum keratitis.

PMID- 29176456 TI - Appropriate use of laboratory test requests in the emergency department: a multilevel intervention. AB - OBJECTIVE: Laboratory test requests in the emergency department (ED) are increasing worldwide. We evaluated whether a multilevel intervention on the basis of the optimization of test profiles and educational meetings with physicians could reduce the number of tests ordered. PATIENTS AND METHODS: In a single center before and after study design, the 8-month intervention period was compared with the 8-month preintervention period. Laboratory test profiles were reduced from 6 to 2 and the number of tests in each profile was reduced by 50%. All physicians received education about the costs and appropriate use of the tests. Primary outcomes were the number of laboratory blood tests and their costs, with a focus on high-cost tests. Secondary outcomes were ED and laboratory performances (patients' waiting time, number of deaths in ED, re-entry, laboratory turn-around time, and add-on tests). RESULTS: Overall, 61 976 and 61 154 patients were evaluated, respectively, during the intervention and the preintervention period. Laboratory blood test requests were decreased by 207 637 (-36.3%) in the intervention period (P<0.05), which corresponds to a reduction of 337.3 tests/100 patients. Costs were decreased by 608 079&OV0556; (-29.6%, P<0.05), leading to a cost reduction of 981.2&OV0556;/100 patients. High-cost test requests decreased by 11 457 (-27.3%) and contributed toward the overall reduction in costs with 197 206&OV0556; (-30.5%). No significant differences were found in ED and laboratory performances between intervention and preintervention periods. CONCLUSIONS: Optimization of test profiles and education on the costs and appropriate use of the tests significantly reduced laboratory test ordering and costs without affecting ED and laboratory performances. PMID- 29176457 TI - A-Frame free Vascularized Fibular Graft and Femoral Lengthening for Osteosarcoma Pediatric Patients. AB - BACKGROUND: Pediatric limb reconstruction after resection of a malignant tumor presents specific challenges. Multiple surgical techniques have been used to treat these patients. This paper describes a staged surgical technique for the reconstruction of large distal femoral defects due to tumor resection in skeletally immature patients. METHODS: Three pediatric patients with osteosarcoma of the distal femur underwent staged reconstruction. Neoadjuvant chemotherapy was followed by en bloc tumor resection and immediate reconstruction of the distal femoral defect with a vascularized free fibular autograft utilizing a unique A frame construct combined with intramedullary nail fixation. The second stage was a planned gradual lengthening of the healed construct, over a custom-made magnetically driven expandable intramedullary nail. RESULTS: All patients achieved bony union and satisfactory length with minimal complications. The patients all returned to full, unlimited physical activities. CONCLUSIONS: The early results confirm that the described technique is a safe and reliable procedure for the reconstruction of large femoral defects in pediatric patients with osteosarcoma. LEVEL OF EVIDENCE: Level IV-therapeutic. PMID- 29176458 TI - From the Editor. PMID- 29176459 TI - Patient, Primary Care Provider, and Specialist Perspectives on Specialty Care Coordination in an Integrated Health Care System. AB - Successful coordination of specialty care requires understanding the perspectives of patients, primary care providers, and specialists-that is, the specialty care "triad." This study used qualitative methods to compare these perspectives in an integrated health care system, using diabetes specialty care as an exemplar. Primary care providers and endocrinologists relied on interclinician relationships to coordinate care. Clinicians rarely included patients or other staff in their conceptualization of specialty care coordination. Patients often assumed responsibility for specialty care coordination but struggled to succeed. We identified several opportunities to improve coordination across the triad. In an integrated medical system, the shared organizational structure can facilitate these efforts. PMID- 29176460 TI - Primary Care and the Hypertension Care Continuum in Brazil. AB - This study provides estimates of hypertension prevalence, awareness, treatment, and control in Brazil and assesses how well different modes of primary care delivery achieve each of these outcomes. Over one-third of the Brazilian adult population had measured hypertension or prior diagnosis. Nearly 90% of these had recent contact with the health system, but only 65% were aware of their condition. Only 62% of these regularly sought care for hypertension, but of these 92% received treatment. Hypertension control was 33% overall, but increased to 57% among those who received all levels of care. PMID- 29176461 TI - Impact of Hydroxyurea on Anthropometry and Serum 25-Hydroxyvitamin D Among Children With Sickle Cell Disease. AB - OBJECTIVE: To evaluate the impact of hydroxyurea (HU) on nutritional status and serum 25-hydroxyvitamin D (25-OHD) of children with sickle cell disease (SCD). DESIGN: Anthropometry and serum 25-OHD were determined in 98 children with SCD, comprising of 68 in HU-group and 30 in HU-naive group. RESULTS: Underweight was more common among HU-naive group (33.3% vs. 10.3%, P=0.009), while 79.4% of HU group against 56.7% HU-naive had normal body mass index percentile for age and sex, P=0.028. None of the HU-group compared with 13.3% of the HU-naive had severe vitamin D deficiency, P=0.002. The mean 25-OHD of the HU-group was also higher (24.1+/-1.2 vs. 19.1+/-9.8 ng/mL, P=0.007). CONCLUSIONS: HU possibly ameliorate growth retardation and vitamin D deficiency in children with SCD.

It is the second most common primary bone malignancy of children and adolescents, with a peak incidence in the second decade of life. It most often arises in the long bones of the extremities and pelvis. Here, we present a novel case of EWS arising from the mastoid bone in a 5-year-old African American male who presented with symptoms of acute mastoiditis. This unique presentation highlights the importance of considering EWS in a patient who presents with atypical mastoiditis or a rapidly growing mass in the postauricular region.

AB - Pain is a clinical hallmark of sickle cell disease (SCD), and is rarely optimally managed. Cognitive-behavioral therapy (CBT) for pain has been effectively delivered through the Internet in other pediatric populations. We tested feasibility and acceptability of an Internet-delivered CBT intervention in 25 adolescents with SCD (64% female, mean age=14.8 y) and their parents randomized to Internet CBT (n=15) or Internet Pain Education (n=10). Participants completed pretreatment/posttreatment measures. Eight dyads completed semistructured interviews to evaluate treatment acceptability. Feasibility indicators included recruitment and participation rates, engagement and adherence to intervention, and completion of outcome measures. In total, 87 referrals were received from 9 study sites; our recruitment rate was 60% from those families approached for screening. Among participants, high levels of initial intervention engagement (>90%), and adherence (>70%) were demonstrated. Most participants completed posttreatment outcome and diary measures (>75%). Retention at posttreatment was 80%. High treatment acceptability was reported in interviews. Our findings suggest that Internet-delivered CBT for SCD pain is feasible and acceptable to adolescents with SCD and their parents. Engagement and adherence were good. Next steps are to modify recruitment plans to enhance enrollment and determine efficacy of Internet CBT for SCD pain in a large multisite randomized controlled trial. PMID- 29176464 TI - A Giant Ear!

PMID- 29176465 TI - Can Pediatric Risk of Mortality Score (PRISM III) Be Used Effectively in Initial Evaluation and Follow-up of Critically Ill Cancer Patients Admitted to Pediatric Oncology Intensive Care Unit (POICU)? A Prospective Study, in a Tertiary Cancer Center in Egypt. AB - Pediatric Risk of Mortality Score (PRISM III-12) is a physiology-based predictor for risk of mortality. We conducted prospective study from January 1, 2014 to 2015 in pediatric oncology intensive care unit (POICU) at South Egypt Cancer Institute, Egypt to explore the ability of 1st PRISM III-12 to predict the risk of mortality in critically ill cancer patients and the ability of serial PRISM III measured every 72 hours to follow-up the patients' clinical condition during POICU stay. In total, 123 (78 males) children were included. Median age was 5 years (1 to 15 y). Death rate was 20%. 1st PRISM III-12 mean was 19 (0 to 61). The mean 1st PRISM III-12 for survivors was significantly higher compared with nonsurvivors (15 vs. 37 respectively; P<0.001). 1st PRISM III-12 mean was significantly correlated to the reasons for admission and organ failures' number (P<0.001 and <0.001). 1st PRISM III-12 correlated weakly positive with the length of stay (r=0.2; P=0.024). Receiver operator curve for 1st PRISM III-12 was 0.913 (95% confidence interval, 0.85-0.98; P<0.001). Decline in serial PRISM III was significantly correlated with favorable (survivor) outcome (P<0.001). We concluded that PRISM III-12 can be used effectively in predicting the risk of mortality and following the clinical condition of patients during POICU stay. PMID- 29176466 TI - The Challenge of Next Generation Sequencing in a Boy With Severe Mononucleosis and EBV-related Lymphoma. AB - A severe course of infectious mononucleosis should always lead up to the suspicion of a primary immunodeficiency. We describe the case of a boy with severe mononucleosis accompanied by the development of hemophagocytic lymphohistiocytosis and lymphoma. By whole exome sequencing, we identified a mutation of uncertain significance in CTPS2, a gene closely related to CTPS1, which is involved in a primary immune deficiency with susceptibility to herpesviruses. We discuss the challenge of a correct interpretation of data from whole exome sequencing, questioning whether the CTPS2 variant found in our patient is just an incidental finding or a mutation with variable penetrance. PMID- 29176467 TI - Quantitative Imaging in the Abdomen. PMID- 29176469 TI - Diffusion Quantification in Body Imaging. AB - Diffusion-weighted imaging (DWI) is increasingly incorporated into routine body magnetic resonance imaging protocols. DWI can assist with lesion detection and even in characterization. Quantitative DWI has exhibited promise in the discrimination between benign and malignant pathology, in the evaluation of the biologic aggressiveness, and in the assessment of the response to treatment. Unfortunately, inconsistencies in DWI acquisition parameters and analysis have hampered widespread clinical utilization. Focusing primarily on liver applications, this article will review the basic principles of quantitative DWI. In addition to standard mono-exponential fitting, the authors will discuss intravoxel incoherent motion and diffusion kurtosis imaging that involve more sophisticated approaches to diffusion quantification. PMID- 29176468 TI - Fat Quantification in the Abdomen. AB - Fatty liver disease is characterized histologically by hepatic steatosis, the abnormal accumulation of lipid in hepatocytes. It is classified into alcoholic fatty liver disease and nonalcoholic fatty liver disease, and is an increasingly important cause of chronic liver disease and cirrhosis. Assessing the severity of hepatic steatosis in these conditions is important for diagnostic and prognostic purposes, as hepatic steatosis is potentially reversible if diagnosed early. The criterion standard for assessing hepatic steatosis is liver biopsy, which is limited by sampling error, its invasive nature, and associated morbidity. As such, noninvasive imaging-based methods of assessing hepatic steatosis are needed. Ultrasound and computed tomography are able to suggest the presence of hepatic steatosis based on imaging features, but are unable to accurately quantify hepatic fat content. Since Dixon's seminal work in 1984, magnetic resonance imaging has been used to compute the signal fat fraction from chemical shift-encoded imaging, commonly implemented as out-of-phase and in-phase imaging. However, signal fat fraction is confounded by several factors that limit its accuracy and reproducibility. Recently, advanced chemical shift-encoded magnetic resonance imaging methods have been developed that address these confounders and are able to measure the proton density fat fraction, a standardized, accurate, and reproducible biomarker of fat content. The use of these methods in the liver, as well as in other abdominal organs such as the pancreas, adrenal glands, and adipose tissue will be discussed in this review. PMID- 29176470 TI - Quantitative Methods in Abdominal MRI: Perfusion Imaging. AB - Recent improvements in arterial spin labeled (ASL) and vastly undersampled dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) acquisitions are providing a new opportunity to explore the routine use of quantitative perfusion imaging for evaluation of a variety of abdominal diseases in clinical practice. In this review, we discuss different approaches for the acquisition and data analysis of ASL and DCE MRI techniques for quantification of tissue perfusion and present various clinical applications of these techniques in both neoplastic and non-neoplastic conditions in the abdomen. PMID- 29176471 TI - Association of Annular Defect Width After Lumbar Discectomy With Risk of Symptom Recurrence and Reoperation: Systematic Review and Meta-analysis of Comparative Studies. AB - STUDY DESIGN: Systematic review and meta-analysis of comparative studies. OBJECTIVE: To characterize the association of annular defect width after lumbar discectomy with the risk of symptom recurrence and reoperation. SUMMARY OF BACKGROUND DATA: Large annular defect width after lumbar discectomy has been reported to increase risk of symptom recurrence. However, this association has not been evaluated in a systematic manner. METHODS: A systematic literature search of MEDLINE and EMBASE was performed to identify comparative studies of large versus small annular defects following lumbar discectomy that reported symptom recurrence or reoperation rates. Main outcomes were reported with pooled odds ratios (OR) and 95% confidence intervals (CIs). Sensitivity analyses were performed to assess the robustness of the meta-analysis findings. RESULTS: After screening 696 records, we included data from 7 comparative studies involving 1653 lumbar discectomy patients, of whom 499 (30%) had large annular defects and 1154 (70%) had small annular defects. Methodological quality of studies was good overall. The median follow-up period was 2.9 years. The risk of symptom recurrence (OR = 2.5, 95% CI = 1.3-4.5, P = 0.004) and reoperation (OR = 2.3, 95% CI = 1.5-3.7, P < 0.001) was higher in patients with large versus small annular defects. Publication bias was not evident. The associations between annular defect width and risk of symptom recurrence and reoperation remained statistically significant in all sensitivity analyses. CONCLUSION: Annular defect width after lumbar discectomy is an under-reported modifier of patient outcome. Risk for symptom recurrence and reoperation is higher in patients with large versus small annular defects following lumbar discectomy. LEVEL OF EVIDENCE: 2.

PMID- 29176472 TI - Omes of Inflammatory Bowel Disease: A Primer for Clinicians. AB - Recent advances in high-throughput laboratory technologies and bioinformatics tools are redefining how we view inflammatory bowel disease (IBD). Instead of 2 diseases, we now see a diverse set of molecular subtypes. Large-scale investigation of the genome, exome, transcriptome, proteome, metabolome, microbiome, and epigenome are providing transformative insights into the pathophysiology of IBD, with the promise of accurately predicting prognosis and targeting therapy. Understanding these tools and their application is crucial to navigating the molecular era of IBD. This review aims to help the IBD clinician understand, appreciate, and eventually incorporate this coming paradigm shift to improve the care of children with IBD. PMID- 29176474 TI - Hepatic Parenchymal Injury in Crigler-Najjar Type I. AB - BACKGROUND: Crigler-Najjar syndrome type I (CNI) arises from biallelic variants of UGT1A1 that abrogate uridine diphosphate glucuronosyltransferase (UGT1A1) activity resulting in unconjugated hyperbilirubinemia. Historically, liver parenchyma in CNI was considered structurally and histologically normal. Recent review of CNI liver explants revealed fibrosis. Our aim was to investigate the association between hepatic histology and disease phenotype in CNI. METHODS: We extracted data from the medical record at the time of liver transplant from 22 patients with CNI at the Children's Hospital of Pittsburgh, and reviewed explant histology. Continuous data were normally distributed, are presented as mean (+/-1 SD), and analyzed using two-tailed Student t-test. Categorical data were analyzed using the Chi-square test. RESULTS: Both alanine transaminase (ALT; mean 87.4 IU/L) and aspartate transaminase (AST; mean 54.6 IU/L) were elevated. Nine (41%) of 22 explants had significant fibrosis. Pericentral (n = 5), periportal (n = 2), and mixed (n = 2) patterns of fibrosis occurred. A significant difference in mean age of subjects with fibrotic versus non-fibrotic livers (16.1 years vs 10.5 years; P = 0.02) was seen. There were no indices of synthetic liver dysfunction or portal hypertension. Neither a history of gallstone disease nor excess weight appeared to contribute to the development of fibrosis. CONCLUSIONS: For the first time, we report a 41% prevalence of clinically silent, yet histologically significant fibrosis among subjects with Crigler-Najjar type 1. Risk for fibrosis appears to accrue with time, indicating that earlier intervention may be prudent whenever considering alternative treatments such as hepatocyte transplant, auxiliary liver transplant, or viral gene therapy. PMID- 29176475 TI - Pneumatosis Cystoides Intestinalis. PMID- 29176476 TI - Safety and Efficacy of Reslizumab for Children and Adolescents With Eosinophilic Esophagitis Treated for 9 Years. AB - BACKGROUND: Eosinophilic esophagitis (EoE) is a chronic disease characterized by infiltration of eosinophils in the esophageal epithelium. There are limited treatment options for EoE. The rationale of the study was to evaluate the long term safety and efficacy of reslizumab (RSZ) in pediatric patients who received RSZ in a randomized controlled trial (RCT) and expanded access program. METHODS: Records of patients who received RSZ in our center were reviewed. Patients received RSZ 2 mg/kg (or placebo) every 4 weeks as part of the RCT, open-label extension (OLE), and compassionate use (CU). Data were analyzed as of their most recent evaluation in August 2017. Labwork, history, and examinations were conducted every 12 weeks. Biopsy results were compared from baseline (before RCT) and at the most recent evaluation. Adverse events (AE) were recorded. RESULTS: Twelve patients entered the RCT at our center; 6 patients completed the OLE and 4 received RSZ through CU. Between the RCT, OLE, and CU periods, patients received 549 doses of RSZ (median 37, range 2-116). No serious AE were attributed to RSZ. Symptoms improved on treatment: dysphagia (42% vs 0%), abdominal pain (58% vs 0%), heartburn (18% vs 0%), vomiting (67% vs. 17%), reflux (58% vs. 0%). Median esophageal eosinophil count improved (35 eosinophils per high-power field vs 3, P < 0.001). Patients receiving RSZ maintain a relatively unrestricted diet. CONCLUSIONS: RSZ appears to be safe in children with EoE over 9 years of treatment experience. Symptoms and eosinophil count improved considerably during treatment with RSZ despite a relatively unrestricted diet. PMID- 29176477 TI - Noninvasive Methods of Predicting Large Esophageal Varices in Children With Intrahepatic Portal Hypertension. AB - OBJECTIVE: Esophageal variceal bleeding is a severe complication of portal hypertension. The standard diagnostic screening test and therapeutic procedure for esophageal varices (EV) is endoscopy, which is invasive in pediatric patients. This study aimed to evaluate the role of noninvasive parameters as predictors of large varices in children with intrahepatic portal hypertension. METHODS: Participants included in this cross-sectional study underwent a screening endoscopy. Variceal size, red marks, and portal gastropathy were assessed and rated. Patients were classified into two groups: Group 1 (G1) with small or no varices and Group 2 (G2) with large varices. The population consisted of 98 children with no history of gastrointestinal (GI) bleeding, with a mean age of 8.9 +/- 4.7 years. The main outcome evaluated was the presence of large varices. RESULTS: The first endoscopy session revealed the presence of large varices in 32 children. The best noninvasive predictors for large varices were platelets (Area under the ROC Curve [AUROC] 0.67; 95% CI 0.57-0.78), the Clinical Prediction Rule (CPR; AUROC 0.65; 95% CI 0.54-0.76), and risk score (AUROC 0.66; 95% CI 0.56-0.76). The logistic regression model showed that children with a CPR value under 114 were 8.59 times more likely to have large varices. Risk scores higher than -1.2 also increased the likelihood of large varices (OR 6.09; P = 0.014), as did a platelet count/spleen size z score lower than 25 (OR 3.99; P = 0.043). The combination of these three tests showed a high negative predictive value. CONCLUSIONS: The CPR, the risk score, and the platelet count/spleen size z score could be helpful in identifying cirrhotic children who may be eligible for endoscopy. PMID- 29176478 TI - Vitamin B1 Deficiency Related to Excessive Soft Drink Consumption in Japan. AB - The aim of this study was to clarify the picture of vitamin B1 deficiency (VB1D) caused by excessive soft drink consumption in Japan. A nationwide survey of children with soft drink-induced VB1D was conducted using a structured research form. Patient information was obtained from 2 sources: training hospitals for board-certified pediatricians and those identified by a database search. We obtained data from 33 children. Twenty-one children had a nonnurturing home environment. The median duration of excessive soft drink intake was 3.5 months and the daily intake was 1000 mL or more in 25 children. Infection was the most common reason for excessive soft drink consumption. Only 4 children had the classical triad of Wernicke encephalopathy. One child died, and 12 had neurological sequelae. A majority of children with soft drink-induced VB1D did not have a nurturing home environment. It is imperative to establish measures to prevent future cases of VB1D. PMID- 29176479 TI - Effect of Long-Term Diving on the Morphology and Growth of the Distal Radial Epiphyseal Plate of Young Divers: A Magnetic Resonance Imaging Study. AB - OBJECTIVE: To investigate the effects of long-term diving on the morphology and growth of the distal radial epiphyseal plate in young divers. STUDY DESIGN: Cohort study. SETTING: Guangzhou Sport University. PARTICIPANTS: Thirty-eight professional divers, aged 10 to 17 years, and 25 age-matched volunteers. INTERVENTIONS: Each subject received a physical examination at the beginning of the study and underwent bilateral magnetic resonance imaging of the wrist. The divers were divided into 2 groups depending on the status of the epiphyseal plate: group A (positive distal radial epiphyseal plate injury) and group B (no positive distal radial epiphyseal plate injury). A third group, group C, consisted of the 25 volunteers. MAIN OUTCOME MEASURES: The frequency of distal radial epiphyseal plate injury and the thickness of the distal radial epiphyseal plate were analyzed across the 3 groups. RESULTS: Twenty-nine cases (29/76, 38.15%) of distal radial epiphyseal plate injury were observed in 20 divers (20/38, 52.63%). The incidence of injury to the right hand was higher than that for the left (P = 0.009). There were statistically significant differences (P = 0.000) among the 3 groups in terms of epiphyseal plate thickness; group A > group B > group C. CONCLUSIONS: Distal radial epiphyseal plate injury is common in divers, and more injuries are seen in the right hand. Moreover, growth of the radius was impaired in divers relative to controls. We consider that loading during diving may influence growth of the epiphyseal plate in either a transient or permanent manner. PMID- 29176480 TI - How does sinus surgery affect topical irrigation distribution? AB - PURPOSE OF REVIEW: The current article reviews the literature on the distribution of nasal irrigation in the treatment of chronic sinusitis, especially in how sinus surgery and irrigation techniques affect its delivery to the nasal cavity and paranasal sinuses. RECENT FINDINGS: Nasal irrigation has become a useful tool in the treatment of chronic sinusitis. Used after endoscopic surgery of the paranasal sinuses, irrigation has shown to be effective in improving edema and removing crusts and secretions in that place. However, some relevant points have been considered in the surgical technique and in the postoperative period to improve irrigation access to the paranasal sinuses such as the amplitude of the sinus ostial opening, irrigation volume and device used, as well as head position during irrigation. SUMMARY: Postoperative lavage of the paranasal sinus is a recognized adjuvant in the treatment of chronic rhinosinusitis, reducing morbidity and improving local healing, besides allowing the association of topical medications that can be carried to the paranasal sinuses along with the saline increasing the reach of these drugs. Detailed attention to the techniques described in this review improves the distribution of irrigation in the paranasal sinuses after sinus surgery and considerably increases the efficacy of this therapy. PMID- 29176481 TI - The asthma-obesity relationship: underlying mechanisms and treatment implications. AB - PURPOSE OF REVIEW: Obesity is a worldwide epidemic with a prevalence that has tripled in the last two decades. Worldwide, more than 1.5 billion adults are overweight and more than 500 million obese. Obesity has been suggested to be a risk factor for the development of more difficult-to-control asthma. Although the mechanisms underlying the asthma-obesity relationship are not fully understood, several possible explanations have been put forward. These will be reviewed in this manuscript as well as the implications for the treatment of overweight and obese asthma patients. RECENT FINDINGS: Insulin resistance is a possible factor contributing to the asthma-obesity relationship and the effect is independent of other components of the metabolic syndrome such as hypertriglyceridemia, hypertension, hyperglycemia, and systemic inflammation. Obesity has important effects on airway geometry, by especially reducing expiratory reserve volume causing obese asthmatics to breathe at low lung volumes. Furthermore, obesity affects the type of inflammation in asthma and is associated with reduced inhaled corticosteroids treatment responsiveness. SUMMARY: Obesity induces the development of asthma with a difficult-to-control phenotype. Treatment targeting insulin resistance may be beneficial in obese asthma patients, especially when they have concomitant diabetes. Systemic corticosteroids should be avoided as much as possible as they are not very effective in obese asthma and associated with side-effects like diabetes, weight gain, and osteoporosis.

AB - : Consensus statements regarding the evidence-base for lumbar total disc replacement, as it pertains to payer decision-making, were developed through a modified-Delphi technique involving 17 spine surgeons and a former payer medical director. The Delphi process involved one round of anonymous survey and one round with a face-to-face meeting. The survey was a 51-item, electronically administered questionnaire to determine level of agreement with proposed statements on the evidence for lumbar total disc replacement and to provide additional diagnosis and management practice information for further deliberations. A subset of the proposed statements was discussed at the face-to face meeting to identify reasons for disagreement, revise wording, and obtain consensus. The meeting involved presentation of the current evidence base for lumbar total disc replacement, as well as three themed sessions that were moderated by surgeons on the panel. The voting processes during meeting deliberations remained anonymous. Consensus was defined as >= 90% agreement. Consensus was reached on 11 statements, divided into themes that focused on patient eligibility and diagnosis, evidence criteria for coverage decisions, clinical evidence, and budgetary implications. PMID- 29176483 TI - Foreword: Proceedings From the First Annual Lumbar Total Disc Replacement Summit. AB - : This publication focuses on proceedings from the First Annual Lumbar Total Disc Replacement Summit, held October 25, 2016 in Boston, MA. The Summit brought together 17 thought leading surgeons who employed a modified-Delphi method to determine where consensus existed pertaining to the utilization of lumbar total disc replacement as a standard of care for a subpopulation of patients suffering from degenerative disc disease. PMID- 29176485 TI - Defining the Ideal Lumbar Total Disc Replacement Patient and Standard of Care. AB - : Lumbar total disc replacement, now in use since 2004, was determined by the panel to be a standard of care for the treatment of symptomatic single-level lumbar degenerative disc disease in the active patient subpopulation as outlined by the investigational device exemption study criteria. The large body of evidence supporting this statement, including surgeons' experiences, was presented and discussed. Consensus statements focusing on decision-making criteria reflected that efficacy, long-term safety, clinical outcomes with validated measures, and cost-effectiveness should form the basis of decision making by payers. Diagnostic challenges with lumbar degenerative disc disease patients were discussed among the panel, and it was concluded that although variably used among surgeons, reliable tools exist to appropriately diagnose discogenic back pain. PMID- 29176486 TI - Challenges and Solutions for Lumbar Total Disc Replacement Implantation. AB - : Long-term data are now available to support the safety and efficacy of lumbar total disc replacement (TDR). Five-year randomized and controlled trials, meta analyses, and observational studies support a similar or lower risk of complications with lumbar TDR compared with fusion. The panel concluded that published data on commercially available lumbar TDR devices demonstrate minimal concerns with late-onset complications, and that the risk of adjacent segment degeneration and reoperations can be reduced with lumbar TDR versus fusion. Survey results of surgeon practice experiences supported the evidence, revealing a low rate of complications with TDR. Panelists acknowledged the importance of adhering to selection criteria to help minimize patient complications. PMID- 29176487 TI - Barriers to and Budget Impact of Lumbar Total Disc Replacement Utilization. AB - : Evidence on the favorable efficacy, safety, and cost effectiveness of lumbar total disc replacement (TDR) compared with fusion for lumbar degenerative disc disease is mounting; however, a key barrier identified for TDR utilization is lack of coverage by US health insurers. Although economic considerations in a fee for-service model should not be a determining factor in patient access, concerns regarding the budget impact of lumbar TDR surgery may unfortunately underlie coverage decisions. On the basis of the data available and economic modeling, the panel agreed that there is no indication that there would be a dramatic increase in patients seeking lumbar TDR. Considering several possible scenarios on potential growth in TDR utilization with coverage, as well as growth in the overall surgical pool of patients, economic modeling demonstrated that adoption of lumbar TDR would result in minimal or no budget impact for commercial insurance plans. Considering these model results and the economic literature, the panel concluded that adopting lumbar TDR within a coverage policy is expected to remain cost neutral for the insurer.

AB - STUDY DESIGN: Evidence-based systematic review. OBJECTIVES: To define the optimal treatment of fractures involving the C2 body, including those with concomitant injuries, based upon a systematic review of the literature. SUMMARY OF BACKGROUND DATA: Axis body fractures have customarily been treated nonoperatively, but there are some injuries that may require operative intervention. High-quality literature is sparse and there are few class I or class II studies to guide treatment decisions. MATERIALS AND METHODS: A literature search was conducted using PubMed (MEDLINE), Cochrane Central Register of Controlled Trials, and Scopus (EMBASE, MEDLINE, COMPENDEX). The quality of literature was rated according to a grading tool developed by the Center for Evidence-based Medicine. Operative and nonoperative treatment of axis body fractures were compared using fracture bony union as the primary outcome measure. As risk factors for nonunion were not consistently reported, cases were analyzed individually. RESULTS: The literature search identified 62 studies, of which 10 were case reports which were excluded from the analysis. A total of 920 patients from 52 studies were included. The overall bony union rate for all axis body fractures was 91%. Although the majority of fractures were treated nonoperatively, there has been an increasing trend toward operative intervention for Benzel type III (transverse) axis body fractures. Nearly 76% of axis body fractures were classified as type III fractures, of which 88% united successfully. Nearly all Benzel type I and type II axis body fractures were successfully treated nonoperatively. The risk factors for nonunion included: a higher degree of subluxation, fracture displacement, comminution, concurrent injuries, delay in treatment, and older age. CONCLUSIONS: High rates for fracture union are reported in the literature for axis body fractures with nonoperative treatment. High-quality prospective studies are required to develop consensus as to which C2 body fractures require operative fixation. PMID- 29176490 TI - Incidental Durotomy in Open Versus Tubular Revision Microdiscectomy: A Retrospective Controlled Study on Incidence, Management, and Outcome. AB - STUDY DESIGN: Retrospective case-control study. OBJECTIVE: To compare the incidence, management, and outcome of incidental durotomy in revision microdiscectomy with open and minimal-access surgery. SUMMARY OF BACKGROUND DATA: Incidental durotomy occurs with a variable incidence of 3%-27% in spine surgery. The highest rate occurs in revision microdiscectomy. The intraoperative and postoperative management of dural tears varies in the literature and the definite impact on clinical outcome has to be clarified. METHODS: This is a retrospective study of medical records of 135 patients who underwent revision microdiscectomy, divided into 2 subgroups: OPEN (n=82) versus minimal-access surgery (MINI, n=53). Occurrence of intraoperative dural tears, intraoperative and postoperative management of durotomy, and clinical outcomes, according to MacNab criteria, were retrospectively examined. Statistical comparisons for categorical values between groups were accomplished using the 2-tailed Fisher exact test. P-values <0.05 were considered to be statistically significant. RESULTS: The incidence of durotomy in group OPEN was 19.5% (n=16/82) and in group MINI 17.0% (n=9/53) (P=0.822). The majority of durotomies (23/25) were repaired with an absorbable fibrin sealant patch alone. Postoperative cerebrospinal fluid fistula occurred only in 1 case of the OPEN group and was treated with lumbar drainage without the need for a reoperation. Patients with durotomy of the MINI group tended to have better outcome compared with those of the OPEN group without being statistically significant. CONCLUSIONS: The incidence of durotomy and postoperative cerebrospinal fluid fistula in lumbar revision microdiscectomy does not significantly differ between minimal-access and standard open procedures. The application of a fibrin sealant patch alone is an effective strategy for dural repair in revision lumbar microdiscectomy. PMID- 29176491 TI - Impact of Anemia and Transfusion on Readmission and Length of Stay After Spinal Surgery: A Single-center Study of 1187 Operations. AB - STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To determine whether receipt of blood transfusion and preoperative anemia are associated with increased rates of 30-day all-cause readmission, and secondarily with a prolonged hospital stay after spinal surgery. SUMMARY OF BACKGROUND DATA: Increased focus on health care quality has led to efforts to determine postsurgical readmission rates and predictors of length of postoperative hospital stay. Although there are still no defined outcome measures specific to spinal surgery to which providers are held accountable, efforts to identify appropriate measures and to determine modifiable risk factors to optimize quality are ongoing. METHODS: Records from 1187 consecutive spinal surgeries at Northwestern Memorial Hospital in 2010 were retrospectively reviewed and data were collected that described the patient, surgical procedure, hospital course, complications, and readmissions. Presence or absence of transfusion during the surgery and associated hospital course was treated as a binary variable. Multivariate negative binomial regression and logistic regression were used to model length of stay and readmission, respectively. RESULTS: Nearly one fifth (17.8%) of surgeries received transfusions, and the overall readmission rate was 6.1%. After controlling for potential confounders, we found that the presence of a transfusion was associated with a 60% longer hospital stay [adjusted incidence rate ratio=1.60 (1.34-1.91), P<0.001], but was not significantly associated with an increased rate of readmission [adjusted odds ratio=0.81 (0.39-1.70), P=0.582]. Any degree of preoperative anemia was associated with increased length of stay, but only severe anemia was associated with an increased rate of readmission. CONCLUSIONS: Both receipt of blood transfusion and any degree of preoperative anemia were associated with increased length of hospital stay after controlling for other variables. Severe anemia, but not receipt of blood transfusion, was associated with increased rate of readmission. Our findings may help define actions to reduce length of stay and decrease rates of readmission. PMID- 29176492 TI - The Weight-Bearing Shoulder. AB - The shoulder achieves a wide spectrum of motion, and in a subset of patients, including those who use manual wheelchairs and upper extremity walking aids, the shoulder also serves as the primary weight-bearing joint. Because the weight bearing shoulder is subject to considerable joint reaction forces and overuse, a broad spectrum of pathology can affect the joint. The combination of muscle imbalance and repetitive trauma presents most commonly as subacromial impingement syndrome but can progress to other pathology. Patients with high-level spinal cord injury, leading to quadriplegia and motor deficits, have an increased incidence of shoulder pain. Understanding the needs of patients who use manual wheelchairs or walking aids can help the physician to better comprehend the pathology of and better manage the weight-bearing shoulder. PMID- 29176493 TI - The Relative Effects of Manual Versus Automatic Exposure Control on Radiation Dose to Vital Organs in Total Hip Arthroplasty. AB - INTRODUCTION: Technologic advances have reduced medical radiation exposure while maintaining image quality. The purpose of this study was to determine the effects of the presence of total hip arthroplasty implants, compared with native hips, on radiation exposure of the most radiosensitive organs when manual and automatic exposure control settings are used. METHODS: Detection probes were placed at six locations (stomach, sigmoid colon, right pelvic wall, left pelvic wall, pubic symphysis, and anterior pubic skin) in a cadaver. Radiographs were obtained with the use of manual and automatic exposure control protocols, with exposures recorded. A total hip arthroplasty implant was placed in the cadaver, probe positioning was confirmed, and the radiographs were repeated, with exposure values recorded. RESULTS: The control probe placed at the stomach had values ranging from 0.00 mSv to 0.01 mSv in protocols with and without implants. With the manual protocol, exposures in the pelvis ranged from 0.36 mSv to 2.74 mSv in the native hip and from 0.33 mSv to 2.24 mSv after implant placement. The increases in exposure after implant placement, represented as relative risk, were as follows: stomach, 1.000; pubic symphysis, 0.818; left pelvic wall, 1.381; sigmoid colon, 1.550; right pelvic wall, 0.917; and anterior pubic skin, 1.015. With automatic exposure control, exposures in the pelvis ranged from 0.07 mSv to 0.89 mSv in the native hip and from 0.21 mSv to 1.15 mSv after implant placement. With automatic exposure control, the increases in exposure after implant placement, represented as relative risk, were as follows: stomach, 1.000; pubic symphysis, 1.292; left pelvic wall, 1.476; sigmoid colon, 2.182; right pelvic wall, 3.000; and anterior pubic skin, 1.378. DISCUSSION: The amount of radiation to which patients are exposed as a result of medical procedures or imaging, and whether exposure is associated with an increased risk of malignant transformation, are the subject of ongoing debate. We found that after insertion of a total hip arthroplasty implant, exposure values increased threefold at some anatomic locations and surpassed 1 mSv, the generally accepted threshold for concern. CONCLUSION: Radiation exposure to radiosensitive organs increased up to threefold after total hip implantation with automatic exposure control and up to approximately 1.5 times with the manual protocol. Doses were greater with manual exposures than with automatic exposure control (except at the control probe on the stomach, where exposure was negligible, as expected). However, after implant placement, doses increased more with automatic exposure control than with manual exposure. This difference can be attributed to increased scatter and the difficulty of dose modification because of the density of the implant. Current radiographic protocols should be reassessed to determine if the benefits of frequent radiographs outweigh the newly demonstrated risks. PMID- 29176495 TI - Soft Factors, Smooth Transport? The role of safety climate and team processes in reducing adverse events during intrahospital transport in intensive care. AB - BACKGROUND: Intrahospital patient transports (IHTs) in intensive care involve an appreciable risk of adverse events (AEs). Research on determinants of AE occurrence during IHT has hitherto focused on patient, transport, and intensive care unit (ICU) characteristics. By contrast, the role of "soft" factors, although arguably relevant for IHTs and a topic of interest in general health care settings, has not yet been explored. PURPOSE: The study aims at examining the effect of safety climate and team processes on the occurrence of AE during IHT and whether team processes mediate the effect of safety climate. METHODOLOGY/APPROACH: Data stem from a noninterventional, observational multicenter study in 33 ICUs (from 12 European countries), with 858 transports overall recorded during 28 days. AEs include medication errors, dislodgments, equipment failures, and delays. Safety climate scales were taken from the "Patient Safety Climate in Healthcare Organizations" (short version), team processes scales from the "Leiden Operating Theatre and Intensive Care Safety" questionnaire. Patient condition was assessed with NEMS (Nine Equivalents of Nursing Manpower Use Score). All other variables could be directly observed. Hypothesis testing and assessment of effects rely on bivariate correlations and binomial logistic multilevel models (with ICU as random effect). FINDINGS: Both safety climate and team processes are comparatively important determinants of AE occurrence, also when controlling for transport-, staff-, and ICU-related variables. Team processes partially mediate the effect of safety climate. Patient condition and transport duration are consistently related with AE occurrence, too. PRACTICE IMPLICATIONS: Unlike most patient, transport, and ICU characteristics, safety climate and team processes are basically amenable to managerial interventions. Coupled with their considerable effect on AE occurrence, this makes pertinent endeavors a potentially promising approach for improving patient safety during IHT. Although literature suggests that safety climate is slow and hard to change (also compared to team processes), efforts to improve safety climate should not be forgone. PMID- 29176494 TI - Pancreatic Enzyme Replacement Therapy Use in Infants With Cystic Fibrosis Diagnosed by Newborn Screening. AB - OBJECTIVES: The aim of the study is to describe pancreatic enzyme practices during the first year of life in infants with cystic fibrosis (CF) and evaluate associations between dosing and outcomes, including growth and gastrointestinal (GI) symptoms. METHODS: We analyzed data from a subset of infants who were in a prospective cohort study conducted at 28 US CF centers. Anthropometric measurements and medications were recorded at each visit. Diaries with infant diet, pancreatic enzyme replacement therapy (PERT) dosing, stool frequency and consistency, and pain were completed by a parent/guardian for 3 days before each visit. RESULTS: Two hundred and thirty-one infants were enrolled in the main study; 205 of these met criteria for pancreatic insufficiency (PI). PERT dose between birth and 6 months was on average 1882 LU/kg per meal (range: 492-3727) and was similar between 6 and 12 months (mean: 1842 LU/kg per mean, range: 313 3612). PERT dose had a weak, negative association with weight z score at 3 and 6 months (r = -0.16, 95% confidence interval [CI] -0.29 to -0.02 and r = -0.18, 95% CI -0.31 to -0.04, respectively) but not at 12 months. There was not a clear relationship between PERT dosing and number of stools per day, stool consistency or pain. One hundred and forty-four infants (70%) were placed on acid suppression medication. Weight z score mean was 0.37 higher in infants using proton pump inhibitors (PPIs) exclusively versus those using histamine-2 blockers exclusively (95% CI -0.02 to 0.76, P = 0.06). CONCLUSIONS: We did not observe that centers with a higher PERT dosing strategy yielded greater clinical benefit than dosing at the lower end of the recommended range. PMID- 29176496 TI - Hospitals' adoption of medical device registers: Evidence from the German Arthroplasty Register. AB - BACKGROUND: Hospitals in many countries do not record and analyze artificial hip and knee joint surgeries systematically, leading to a lack of reliable quality assurance data. Arthroplasty registers have the potential to alleviate this and improve quality of care and health care expenditures. In Germany, the current introduction of the Arthroplasty Register acts as a prototype for various medical device registers. However, participation is voluntary for hospitals in most countries, leading to problems with nonadoption. PURPOSE: Implementing successful registers requires adoption by most relevant hospitals. Therefore, we assess variables influencing medical device register adoption. METHODOLOGY: We collect longitudinal data from 343 hospitals that are potential adopters of the German Arthroplasty Register in two surveys. The first survey on the implementation process is conducted in 2014; the second survey is conducted in 2016 to collect data on actual adoption of the surveyed hospitals in 2014. The survey data are matched with published hospital characteristics and administrative data. The hypotheses are tested with a mediated regression model, using partial least squares structural equation modeling. FINDINGS: Hospital specialization positively affects adoption, directly and indirectly, depending on top management support and user involvement. Quality benefits and hospital size impact adoption positively; economic benefits impact adoption negatively. CONCLUSION: Important factors influencing adoption of medical device registers for the first time were revealed in this study, providing a starting point to influence adoption proactively and avoid nonadoption. PRACTICE IMPLICATIONS: The results provide important guidelines for decision-makers at hospitals, registers, and health insurance companies and policy makers about how to foster register adoption and encourage hospitals toward adopting medical device registers. PMID- 29176497 TI - Agreement Among Clinician, Patient, and Independent Interviewer Ratings of Adaptive Functioning. AB - We examined the interrater reliability and diagnostic efficiency of clinician report (both the treating clinician and independent expert clinical interviewer) and patient self-report of clinically meaningful information pertaining to adaptive functioning. A convenience sample of clinicians (N = 80) and patients (N = 170) from eight community mental health clinics in Israel participated in the study. Our findings suggest that clinicians overall reliably report on adaptive functioning of patients (overall correct classification rates range, 0.74-0.98). Yet, in some areas, they may fail to collect necessary information such as self mutilation history, loss of job in the past 5 years, and adult physical abuse. The patterns of higher versus lower diagnostic efficiency suggest that both treating clinicians and independent clinician interviewers tend to make judgments conservatively, essentially sacrificing sensitivity for specificity, not diagnosing events unless they were certain, thus maximizing false-negatives and minimizing false-positives. PMID- 29176500 TI - A Pilot Study of a Topical Intervention for Treatment of Female Sexual Dysfunction. AB - PURPOSE/BACKGROUND: Many investigators reported that pharmacological treatment of female sexual dysfunction (FSD) has been a promising field yet to be explored. The purpose of this pilot study was to investigate the efficacy and safety of a topical cream containing small concentrations of three vasodilators with different mechanisms of action in treating FSD. METHODS: In this randomized, controlled pilot trial, premenopausal (n = 30) and postmenopausal (n = 30) cases of 21- to 62-year age range with FSD were allocated randomly into 15 given placebo or 15 given active cream in each group. The women included had FSD for more than a 6-month duration and a total score of Female Sexual Distress Scale Revised of at least 15. Assessing sexual function by measuring female sexual function index (FSFI) during five clinic visits, one at the end of baseline week and at the end of each week of the 4-week treatment period. The primary end point was changed from baseline FSFI total scores to week 4 treatment. Secondary end point included the changes from baseline arousal, desire, orgasm, and satisfaction scores to week 4 treatment. FINDINGS/RESULTS: The sexual problem reported by patients was orgasmic or/and arousal disorders. In premenopausal cases, active cream led to a high significant increase in mean change FSFI total score from the baseline to week 4 compared with placebo (1.7 +/- 1.886 vs 13.35 +/- 4.646, respectively; P < 0.0001). Greater improvement of mean change of orgasm and arousal domain score was also observed (0.3 +/- 0.45 and 0.35 +/- 0.39 vs. 2.66 +/- 0.63 and 1.87 +/- 0.168, respectively; P < 0.0001). In postmenopausal cases, there were significantly greater improvements with active cream in all sexual functions compared with placebo cream (P < 0.0001). In triple cream, mean change of FSFI total score, orgasm domain score, and arousal score domain were 14.85 +/- 6.33, 1.87 +/- 0.168 and 2.66 +/- 1.182, whereas in the placebo cream, they were 1.54 +/- 2.1,0.7 +/- 0.76 and 0.22 +/- 0.44, respectively. Meanwhile, orgasm scores increased significantly after the use of placebo cream. No serious adverse effects were reported during treatment. IMPLICATIONS/CONCLUSIONS: The results of the pilot trial suggest that topical cream containing small concentrations of three vasodilators may act synergistically, and was effective in improving arousal, orgasmic, and satisfaction disorder with a safer profile for premenopausal and postmenopausal women with FSD. Further studies are recommended to be conducted using a large number of nondepressive and depressive patients. PMID- 29176501 TI - Phase IIIb safety results from an expanded-access protocol of talimogene laherparepvec for patients with unresected, stage IIIB-IVM1c melanoma. AB - Talimogene laherparepvec is a genetically modified herpes simplex virus-1-based oncolytic immunotherapy for the local treatment of unresectable cutaneous, subcutaneous, and nodal tumors in patients with melanoma recurrence following surgery. We aim to describe the safety of talimogene laherparepvec. Intralesional talimogene laherparepvec was administered at less than or equal to 4 ml*10 PFU/ml at protocol day 1, then less than or equal to 4 ml*10 PFU/ml 21 days later, and then every 14 days. Treatment continued until complete response, absence of injectable tumors, progressive disease, intolerance, or US Food and Drug Administration approval. Adverse events were graded during and 30 days after the end of treatment. Lesions suspected to have herpetic origin were tested for talimogene laherparepvec DNA by quantitative PCR (qPCR). Between September 2014 and October 2015, 41 patients were enrolled with stage IIIB (22%), IIIC (37%), IVM1a (34%), IVM1b (5%), and IVM1c (2%) melanoma. The median age was 72 (range: 32-96) years and 54% of the patients were men. Patients had an ECOG performance status of 0 (68%) or 1 (32%). The median treatment duration was 13.1 (3.0-41.1) weeks. Treatment-related adverse events of greater than or equal to grade 3 were reported in three (7.3%) patients and included vomiting, upper abdominal pain, chills, hyperhidrosis, nausea, pyrexia, and wound infection. Suspected herpetic lesions were swabbed in five (12%) patients. One of the five tested positive for talimogene laherparepvec DNA by qPCR, but this lesion had been injected previously with talimogene laherparepvec. During the study, five patients completed treatment because of complete response per investigators. In the clinical practice setting, talimogene laherparepvec has a safety profile comparable to that observed in previous clinical trials. Talimogene laherparepvec (IMLYGIC) is now approved in the US, European Union, and Australia. PMID- 29176502 TI - Venous Thromboembolism Prophylaxis in Total Hip Arthroplasty and Total Knee Arthroplasty Patients: From Guidelines to Practice. AB - Venous thromboembolism (VTE) prophylaxis is recommended for all patients undergoing total hip arthroplasty or total knee arthroplasty. The selection of an appropriate prophylaxis regimen represents a balance between efficacy and safety. To help orthopaedic surgeons select an appropriate VTE prophylaxis regimen for their patients, the American Academy of Orthopaedic Surgeons and the American College of Chest Physicians have developed guidelines. These guidelines do not recommend an optimal regimen, however. Rather, an individualized prophylaxis regimen that balances efficacy and safety is recommended for each patient, based on various risk factors. Because of a paucity of data and a lack of adequately powered head-to-head trials, implementing these guidelines can be challenging for the orthopaedic surgeon. Knowledge of the prophylaxis options and the VTE risk factors is paramount for developing an effective VTE prophylaxis algorithm for the surgeon's practice. PMID- 29176498 TI - Zika clinical updates: implications for pediatrics. AB - PURPOSE OF REVIEW: Zika virus (ZIKV), a mosquito-borne flavivirus, has gained recognition over the past few years as an important new cause of congenital infection. As a result, it is critical that pediatricians understand its epidemiology, clinical presentation, clinical sequelae, and management. RECENT FINDINGS: The recent ZIKV epidemiology, clinical presentation of acute infection in children and complications, perinatal infection, and congenital infection will be summarized in this ZIKV review. This will be followed by a brief summary on ZIKV diagnosis, management, treatment, and prevention. SUMMARY: The field of clinical research in ZIKV has rapidly evolved over recent months. It is critical that pediatricians continue to stay up-to-date with the continuously evolving understanding of the clinical aspects of ZIKV to ensure optimal identification and management of affected infants and children. Given the recent changes in Centers for Disease Control and Prevention guidelines to limit screening of asymptomatic pregnant women in the United States with possible ZIKV exposure, comprehensive ZIKV clinical knowledge becomes even more crucial. PMID- 29176503 TI - Diagnostic Injections About the Shoulder. AB - Injections about the shoulder serve diagnostic as well as therapeutic purposes. Diagnosis of shoulder conditions, such as rotator cuff tears, acromioclavicular joint pathology, subacromial impingement or anterolateral pain syndrome, glenohumeral joint pathology, suprascapular nerve entrapment, and biceps tendon pathologies, is often complicated by concomitant conditions with overlapping symptoms and by inconclusive physical examination and imaging results. Injections of anesthetic agents can often help clinicians locate the source of pain. However, technique and accuracy of needle placement can vary by route. Accuracy is often improved with the use of ultrasonography guidance, although studies differ on the benefits of guided versus unguided injection. PMID- 29176504 TI - Screening for Infection Before Revision Hip Arthroplasty: A Meta-analysis of Likelihood Ratios of Erythrocyte Sedimentation Rate and Serum C-reactive Protein Levels. AB - INTRODUCTION: Diagnosing periprosthetic joint infection (PJI) before revision hip arthroplasty is critical to ensure effective treatment of patients undergoing surgery for reasons other than infection. The main objective of our study is to determine whether the erythrocyte sedimentation rate (ESR) and the serum C reactive protein (CRP) level are sufficient to use for testing to rule out infection in patients undergoing revision hip surgery. METHODS: We performed a systematic review of the literature in the MEDLINE, Ovid, and Embase databases. We included studies in which the investigators used the ESR (>30 mm/h) and serum CRP level (>10 mg/L) for the diagnosis of PJI of the hip. We obtained meta estimates of sensitivity, specificity, positive likelihood ratio (LR+), and negative likelihood ratio (LR-). RESULTS: From 511 articles, we analyzed 12 studies in which the investigators reported data on 2,736 patients. Sensitivity and specificity for the ESR were 0.860 (95% confidence interval [CI], 0.825 to 0.890) and 0.723 (95% CI, 0.704 to 0.742), respectively, and for the CRP level were 0.869 (95% CI, 0.835 to 0.899) and 0.786 (95% CI, 0.769 to 0.803), respectively. For the ESR, LR+ was 3.42 (95% CI, 2.55 to 4.59) and LR- was 0.22 (95% CI, 0.12 to 0.41). For the CRP level, LR+ was 4.18 (95% CI, 3.42 to 5.11) and LR- was 0.20 (95% CI, 0.12 to 0.32). DISCUSSION: With a low pretest probability of PJI, a negative test result for either the ESR or CRP level is enough to rule out infection before revision hip arthroplasty. LEVEL OF EVIDENCE: III. PMID- 29176505 TI - Sex-specific Outcomes and Predictors of Concussion Recovery. AB - INTRODUCTION: Sports-related concussion (SRC) is a substantial concern in collegiate athletics. Some studies of SRC that make comparisons by sex are limited by sample size, follow-up duration, or referral bias. Sex-specific predictors of occurrence and recovery are uncertain. METHODS: A 15-year retrospective cohort study identified 1,200 Columbia University varsity athletes (822 male [68.5%], 378 female [31.5%]) at risk of collegiate SRC. RESULTS: A total of 228 athletes experienced at least one collegiate concussion, including 88 female athletes (23.3% of female athletes) and 140 male athletes (17.0% of male athletes) (P = 0.01); follow-up data were available on 97.8% of these athletes. Postconcussion symptoms were similar by sex, with the exception of sleep disturbance (29.3% of male athletes versus 42.0% of female athletes; P = 0.048) and memory impairment (43.6% of male athletes versus 30.7% of female athletes; P = 0.052), although the latter difference was not statistically significant. Risk factors for collegiate concussion included female sex (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.1 to 2.0) or precollegiate concussion (OR, 2.9; 95% CI, 2.2 to 3.9). Prolonged recovery was predicted by the presence of eight or more postconcussion symptoms for all athletes (OR, 3.77; 95% CI, 1.68 to 8.46) and for female athletes only (OR, 8.24; 95% CI, 1.58 to 43.0); this finding was not statistically significant for male athletes. DISCUSSION: Female athletes were more likely than male athletes to experience concussion. Increasing numbers of prior concussions predicted recurrence. Although most postconcussion symptoms were highly intercorrelated, the total number of symptoms predicted a prolonged recovery period. CONCLUSION: This study confirms sex-based differences in SRCs. Longitudinal studies of collegiate cohorts should attempt to limit follow-up bias and offer opportunities to clarify determinants of SRC. PMID- 29176506 TI - Complication Rates After Total Hip and Knee Arthroplasty in Patients With Hepatitis C Compared With Matched Control Patients. AB - BACKGROUND: A paucity of data exists regarding long-term outcomes among patients with hepatitis C who undergo total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS: We queried a database for patients with hepatitis C who underwent THA and TKA. We then identified their rates of several postoperative complications and compared them with the same rates among mutually exclusive matched control cohorts. RESULTS: Patients with hepatitis C who underwent THA and TKA had higher rates of infection, aseptic revision surgery, medical complications, and blood transfusion compared with matched control patients. DISCUSSION: Our findings suggest that patients with hepatitis C who undergo THA and TKA are at increased risk of experiencing several postoperative complications, which could mean a substantial increase in the cost of care. CONCLUSIONS: Further research is needed to establish quantifiable associations between hepatitis C and postoperative complications among patients with the disease who undergo total joint arthroplasty. PMID- 29176507 TI - Variables Affecting Return to Work After Spinal Surgery in a Non-workers' Compensation Population: A Retrospective Cohort Study. AB - INTRODUCTION: Return-to-work (RTW) outcomes following spine surgery are critical information for patients aspiring to return to employment following surgical correction. Among patients receiving workers' compensation (WC), spinal surgery has been repeatedly linked to poor RTW rates. However, among patients not receiving WC, the percentage of patients who return to employment is unclear. METHODS: We conducted a retrospective cohort study of 326 non-WC patients who underwent spinal surgery at two institutions. We determined RTW status and analyzed potential predictors of RTW status. RESULTS: Preoperative work status was the only markedly positive predictor of RTW status; patients who were working prior to their surgery were more likely to return to work after surgery. Patients with at least one comorbidity were less likely to return to employment. All other sociodemographic, surgery-related, and complication variables did not reach statistical significance. However, smoking status, short fusion, and cervical fusion were clinically relevant predictors of a negative RTW status. DISCUSSION: Among non-WC patients, employment before surgery was a positive predictor for RTW status. For patients with a positive comorbidity status, a lower likelihood of returning to employment is predicted. Randomized trials are needed to fully explore the effect of predictor variables on RTW status among non-WC patients. CONCLUSIONS: Patients not receiving WC who underwent spinal surgery had a high chance of returning to employment within 1 year if they had been working at least 3 months before the date of surgery. PMID- 29176508 TI - Resting heart rate and the risk of hypertension and heart failure: a dose response meta-analysis of prospective studies. AB - BACKGROUND: Studies on the relationship of resting heart rate to the risks of hypertension and heart failure have been inconsistent, and the question as to whether there is a linear association between them is unanswered. OBJECTIVE: To evaluate this possible relationship, we carried out a dose-response meta-analysis of studies that looked at risks associated with resting heart rate and hypertension or heart failure. METHODS: We searched PubMed, Embase, CNKI and WanFang databases for articles published before 15 June 2017. A random-effect model was used to pool relative risks and 95% confidence intervals. Restricted cubic spline analysis was used to model the resting heart rate-hypertension and heart failure risk association. RESULTS: We identified 13 and 17 cohort studies for hypertension and heart failure, respectively. The risk for each disease, respectively, increased by 11% relative risk: 1.11 (95% confidence interval: 1.07 1.15) and 19% relative risk: 1.19 (95% confidence interval: 1.13-1.25) for each 10 beats-per-minute increment in resting heart rate. The relationship between resting heart rate and hypertension or heart failure was consistent in most subgroup analyses except for gender subgroups, with no significant association observed in the women subgroup. The results provide no evidence of a nonlinear association of elevated resting heart rate with hypertension and heart failure risk. CONCLUSION: Resting heart rate shows a linear positive association with the incidence of hypertension and heart failure. PMID- 29176509 TI - Doppler indexes of left ventricular systolic and diastolic function in relation to haemodynamic load components in a general population. AB - BACKGROUND: The contribution of central pulsatility to left ventricular (LV) dysfunction might be mediated by the haemodynamic loads of forward (Pf) and backward (Pb) pulse waves. We investigated the relation between echocardiographic indexes of LV function and pulsatile loads derived by wave separation analysis (WSA). METHODS: In 755 participants, we assessed LV dimensions, transmitral blood flow and mitral annular tissue velocities. We derived central pulse pressure (cPP) from radial tonometric recordings and calculated Pf, Pb and their ratio (reflection magnitude) using an automated, pressure-based WSA algorithm. Despite good quality recordings, WSA failed to derive Pf and Pb in 139 participants (18.4%), in particular in older women with unfavourable haemodynamics. Thus, our analysis included 616 participants (46.1% women; mean age, 49.2 years). RESULTS: Age and age explained most of the variance in cPP (36.9%), Pf (18.6%), Pb (41.5%) and reflection magnitude (36.7%; P < 0.0001) and altered the direct correlation between Pf and Pb (Pint < 0.0001). Haemodynamic loads were independently associated with sex, BMI, heart rate, mean arterial pressure, history of diabetes and use of antihypertensive drugs. In multivariable-adjusted analyses, transmitral velocities and E/e' ratio increased with higher cPP, Pf and Pb in men and women. We also observed an age-dependent association of LV radial strain with cPP, Pf and Pb. CONCLUSION: The commercial WSA algorithm holds limited clinical utility given its low feasibility in older participants with unfavourable haemodynamics. LV function indexes were similarly associated with Pf and Pb, favouring the use of the composite cPP for prediction of LV dysfunction. PMID- 29176510 TI - Cardiac function, myocardial mechano-energetic efficiency, and ventricular arterial coupling in normal pregnancy. AB - OBJECTIVE: To assess cardiac function, myocardial mechanoenergetic efficiency (MEE), and ventricular-arterial coupling (VAC) longitudinally during normal pregnancy, and to study if there was an association between cardiac structure and function, and fetal growth. METHODS: Cardiac structure and function, MEE, and ventricular-arterial coupling was assessed longitudinally in 52 healthy nulliparous women at 14, 24, and 34 weeks' gestation and 9-month postpartum. RESULTS: Left atrial diameter increased during pregnancy (30.41 +/- 3.59 mm in the nonpregnant state and 31.02 +/- 3.91, 34.06 +/- 3.58, and 33.9 +/- 2.97 mm in the first, second, and third trimesters, P < 0.001). Left ventricular mass increased 117.12 +/- 45.0 g in the nonpregnant state and 116.5 +/- 33.0, 126.9 +/ 34.5, 128.4 +/- 36 g in the first, second, and third trimesters (P < 0.001). Cardiac output increased from 3.4 +/- 1.2 l/min to 4.3 +/- 0.7 l/min in the second and third trimesters (P < 0.001). Diastolic function decreased as both E/A and e'/a' decreased during pregnancy (P < 0.05 and P < 0.001, respectively). MEE and VAC were retained during pregnancy. Heart rate was associated with birth weight centile in the first (r = 0.41, P = 0.002) and second (r = 0.46, P = 0.002) trimester. CONCLUSION: The increase in cardiac output during normal pregnancy is obtained by an increase in heart rate, followed by structural cardiac changes. The impaired systolic function is accomplished by a deteriorated diastolic function. Despite these rapid changes, the myocardium manages to work efficient with a preserved MEE. Cardiac and arterial adaption to pregnancy seems to appear parallel as evidenced by a preserved VAC.

PMID- 29176511 TI - Payer Policy Behavior Towards Opioid Pharmacotherapy Treatment in Ohio. AB - OBJECTIVE: Few studies examine how payers address the need for improved access to pharmacotherapy for opioid use disorders and the influence of environmental variables on access to opioid agonist and antagonist medications. METHOD: The 52 Ohio Addiction Drug Abuse and Mental Health Services (ADAMHS) Boards that disburse funds for treatment services for the uninsured and underinsured were surveyed to assess coverage for opioid agonist and antagonist treatment medications. Analyses examined public health data on regional opioid addiction patterns, characteristics of the local health insurance market, and their associations with coverage for opioid addiction pharmacotherapy. RESULTS: Most (70%) of the 44 participating ADAMHS Boards paid for opioid treatment medications. For payment policy, all Boards required behavioral therapy to be provided in conjunction with opioid agonist or opioid antagonist therapy, and 27% of the Boards limited length of a buprenorphine therapy regimen. Higher local opioid treatment admission rates were associated with higher rates of Board funding for opioid treatment pharmacotherapy. Environmental variables (eg, overdose fatality rates or the behaviors of private insurance payers) were not associated with ADAMHS support for opioid agonist or antagonist medication. CONCLUSIONS: The analysis highlights the policy preferences of these payers. Follow-up studies should examine the payer decision-making processes, preferences, and attitudes that affect support for pharmacotherapy for opioid dependence. PMID- 29176513 TI - Endocrine therapy in ovarian cancer: where do we stand? AB - PURPOSE OF REVIEW: Hormonal factors play a pivotal role in epithelial ovarian tumorigenesis and steroid receptor expression has been associated with epithelial ovarian cancer (EOC) response and survival in recent studies. However, the degree of activity of endocrine therapy overall and by specific agents remains unclear. The purpose of this work is to summarize the evidence provided by the recent literature on the effectiveness of endocrine treatment for advanced EOC. RECENT FINDINGS: The results of 53 trials of different endocrine therapies in EOC indicate a clinical benefit of 41% [95% confidence interval (CI), 0.34-0.48], with a trend for a higher benefit in those with estrogen receptor (ER) + and/or progesteron receptor (PgR) + tumors. Moreover, the odd ratio for death showed a reduced mortality with endocrine regimens (0.69, 95% CI, 0.50-0.97), with a propensity for a better outcome in first-line and low-grade tumors. SUMMARY: We suggest that ER and PgR have a predictive role and their inhibition by endocrine therapy may be a treatment option for EOC. Randomized clinical trials in the first-line treatment of advanced hormone receptor positive EOC are warranted given the potential cost effectiveness of this approach. PMID- 29176514 TI - Measuring quality of life in individuals with Parkinson's disease attending a self-help club: cross-sectional study in Hungary. AB - The prevalence of Parkinson's disease (PD) increases with aging. The aim of our cross-sectional study was to measure the quality of life of PD patients attending a self-help 'PD club' and to evaluate the potential positive effect of club life on quality of life. Data collection was carried out using questionnaires (PDQ-39, Hungarian version). Altogether, 101 individuals with clinically diagnosed PD were included, and finally 98 persons' data were analyzed. Among the eight dimensions, the highest score was found in 'bodily discomfort' and the lowest in 'social support'. The overall tendency of the results was similar to another Hungarian study, but the scores in all dimensions were significantly lower in our participants. These positive results seem to correlate with attending the 'PD club', indicating the potential beneficial effect of patients' organizations on promoting mental health.

AB - BACKGROUND: Although beneficial, few sexual assault patients seek follow-up healthcare or counseling after a medical forensic examination. Mobile technology interventions may help patients engage in postcare, but there is a dearth of research on patients' utilization of these interventions. The current study examines patients' engagement with a 4-week postassault text message program (iCare), which assessed patients' safety and well-being, if they needed assistance with accessing nonoccupational postexposure prophylaxis, or scheduling appointments for follow-up pregnancy and sexually transmitted infection testing, and their experience with the criminal justice system. METHODS: This pilot study collected data from 40 adult patient records and texting communications between the nurse and patients. We utilized descriptive statistics to examine patient utilization of the program. RESULTS: Sixty-five percent of the patients responded at least once during the program, but only two responded to every text. Nearly a quarter of the patients (22.5%) requested the texts to stop before the end of the program. A larger portion of the patients (42.5%) did not opt out but stopped replying by the third message. The program appeared to be helpful for increasing the amount of communication between the nurse and the patient, but patients rarely utilized the nurse's offers of assistance (e.g., counseling, advocacy). DISCUSSION: Text interventions appear to be effective for relaying information but may be limited for increasing postexamination service utilization for sexual assault patients. Future research should examine areas of patient needs in the weeks and months postexamination that can be addressed in text interventions. PMID- 29176519 TI - Risk Factors for Women Being Under the Influence of Alcohol Compared With Other Illicit Substances at the Time of Committing Violent Crimes. AB - PURPOSE: We investigated women under the influence of alcohol compared with other illicit substances at the time of committing a crime to identify predictors of being under the influence of alcohol and female-enacted crime. METHODS: Analyses of data, obtained from private interviews and examinations of female prison inmates, included regression analyses exploring predictors of being under the influence of alcohol at the time of the crime and predictors of violent crime. In addition, a reanalysis of a previously reported model, predicting conviction of a violent crime, was conducted including a new variable, being under the influence of alcohol at the time of the crime. RESULTS: Those under the influence of alcohol at the time of their crime had experienced greater nonfamilial childhood sexual abuse and traumatic brain injuries with loss of consciousness predating their crime. They were more likely to have committed a violent, rather than nonviolent, crime compared with those under the influence of other substances, with the latter being not significantly different for those not under the influence of any substance. Being under the influence of alcohol increased the risk of committing a violent crime, adjusting for other predictors of female violence. CONCLUSION: Women under the influence of alcohol are at a greater risk for committing violent crimes than those under the influence of other substances. Female nonfamilial childhood sexual abuse and traumatic brain injury victims were at a higher risk for being under the influence of alcohol, in comparison with other substances, at the time of committing a violent crime. PMID- 29176520 TI - Baccalaureate Nursing Students' Perceptions Regarding Autopsy Experiences. AB - PURPOSE: Since 2012, a medical-surgical nursing course at a midsized state university has provided the opportunity for students to view autopsies with a board-certified forensic pathologist. The autopsies are performed at a midsized hospital relatively close to the campus. The purpose of this study was to discover nursing students' perceptions that emerged during the autopsy experience. METHODS: A convenience sample of 23 baccalaureate nursing students took part in the autopsy experience over a 4-month period. Archival data from an online, anonymous questionnaire, completed after the experience, were reviewed and subjected to qualitative analysis. This study was approved by the university's institutional review board. RESULTS: Rich data emerged regarding the students' experiences, including emotional, psychological, and knowledge-based perceptions. CONCLUSION: Autopsies are important learning tools for nursing students, especially those who go into advanced practice nursing and forensic nursing. Anatomy, physiology, and pathophysiology are essential for students to understand as they learn about medical-surgical nursing concepts. Unique emotional characteristics of the students and cause of death of the deceased influenced how some students viewed the autopsy experience. Students reported that processing and debriefing activities were important after viewing autopsies and should be encouraged.

PMID- 29176523 TI - PHOTODYNAMIC THERAPY WITH VERTEPORFIN PLUS INTRAVITREAL BEVACIZUMAB FOR CIRCUMSCRIBED CHOROIDAL HEMANGIOMA: 4 YEARS OF FOLLOW-UP. AB - PURPOSE: To report the anatomical and functional response of combined photodynamic therapy and intravitreal injection of bevacizumab in a patient with symptomatic circumscribed choroidal hemangioma. METHODS: The patient received a single-session full-fluence photodynamic therapy immediately followed by an intravitreal injection of bevacizumab (1.25 mg/0.05 mL). RESULTS: One week after combined therapy, an improvement of best-corrected visual acuity from count fingers to 20/60 and a significant decrease in subretinal fluid were noted. One month later, we observed decreased leakage on fluorescein angiography in all phases of the study. Three months after treatment, the best-corrected visual acuity improved to 20/25 and spectral domain optical coherence tomography scans showed return to normal foveal architecture with no subretinal fluid and completely flat tumor. These findings were maintained during 4 years of follow up. CONCLUSION: Combination therapy was associated with a rapid and persistent resolution of subretinal fluid, improvement of best-corrected visual acuity, and visual stability at 4 years of follow-up. PMID- 29176524 TI - NOVEL CASE OF CLOSTRIDIUM PERFRINGENS ENDOPHTHALMITIS AFTER ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR INJECTION. AB - INTRODUCTION: Endophthalmitis after anti-vascular endothelial growth factor injection is a rare complication but may lead to rapid destruction of structures within the eye. Infection with Clostridium perfringens has not previously been reported in this context. CASE REPORT: A 90-year-old woman presented with endophthalmitis of the right eye, 2 days after an intravitreal injection of ranibizumab. Initial examination showed a high intraocular pressure, refractive to topical treatment, reduced vision, and a hypopyon. Gram stain showed a Gram positive bacillus, which was identified as C. perfringens. Despite the use of intravitreal and intravenous antibiotics, the patient went on to develop cornea scleral melt of the right eye. She required an evisceration on the fifth day after ranibizumab. CONCLUSION: This case describes a unique and virulent pathogen leading to globe loss after an anti-vascular endothelial growth factor injection. C. perfringens, naturally living in feces or soil, is more commonly associated with dirty traumatic open-globe injuries. However, it is an important pathogen to consider when there is rapid destruction of eye structures associated with endophthalmitis. Based on a root cause analysis of this case, our department has introduced patient information leaflets on hand hygiene to educate patients having intraocular injections. PMID- 29176525 TI - NONHEREDITARY IDIOPATHIC FOVEAL RETINOSCHISIS ASSOCIATED WITH NEW-ONSET PROLIFERATIVE DIABETIC RETINOPATHY. AB - PURPOSE: To present a case of idiopathic foveal retinoschisis in a patient with new-onset proliferative diabetic retinopathy. METHODS: Single case report. RESULTS: A 64-year-old African American man with Type 2 diabetes mellitus presented for a routine annual diabetic eye examination with mildly blurred vision at near and distance in the right eye. Fluorescein angiography demonstrated optic nerve leakage consistent with neovascularization of the disk but no leakage on or around the macula in the right eye. Optical coherence tomography demonstrated peripapillary macular retinoschisis within the outer plexiform layer without optic disk pit, epiretinal membrane, or diabetic tractional membrane. He underwent pan-retinal photocoagulation in the right eye; his acuity and schisis remained unchanged at 6-month follow-up. CONCLUSION: This is the first reported case of idiopathic acquired macular schisis with new-onset nontractional proliferative diabetic retinopathy in the same eye. PMID- 29176526 TI - MACULAR HOLE FORMATION AFTER PARS PLANA VITRECTOMY FOR PRIMARY VITREORETINAL LYMPHOMA. AB - PURPOSE: To report a case of primary vitreoretinal lymphoma in which a macular hole developed after a diagnostic pars plana vitrectomy. METHODS: A retrospective interventional case report. RESULTS: A 65-year-old woman presented with worsening vision in the left eye. Fundus examination showed vitreous haze and multifocal, yellow-white infiltrates in the retina and under the retinal pigment epithelium in the left eye. She underwent a diagnostic pars plana vitrectomy in that eye. Undiluted vitreous specimen showed an increased interleukin-10 level (1,470 pg/mL) with an elevated interleukin-10 to interleukin-6 ratio of 15.1; cytologic analysis of the vitreous showed atypical lymphoid cells with large irregular nuclei and scanty cytoplasm. The retinal and sub-retinal pigment epithelial infiltrates responded well to intravitreal methotrexate injections, but a macular hole developed in the left eye. The second pars plana vitrectomy with internal limiting membrane peeling and 20% sulfur hexafluoride gas tamponade successfully closed the macular hole. CONCLUSION: Macular hole closure can be accomplished in eyes receiving intravitreal methotrexate injections for treating primary vitreoretinal lymphoma. PMID- 29176527 TI - CAT SCRATCH DISEASE IMITATING A TOXOCARA GRANULOMA OF THE OPTIC DISK. AB - PURPOSE: The study reports an unusual presentation of a young female patient presenting with a granulomatous posterior pole mass and profound vision loss secondary to infection with Bartonella henselae. METHODS: A single case report in a child. RESULTS: An 8-year-old female presented with a recent history of flu like illness associated with profound vision loss, panuveitis and leukocoria in the left eye. She was found to have a posterior granulomatous mass associated with an exudative retinal detachment presumed as a toxocara granuloma. Magnetic Resonance Imaging ruled out retinoblastoma. Lab work done was negative for toxocariasis and positive for Bartonella henselae titers. She was treated for Cat Scratch Disease (CSD) with steroids and azithromycin. With treatment, the inflammation and exudative retinal detachment resolved, however, the patient had no improvement in visual acuity. CONCLUSIONS: Young patients presenting with leukocoria need a full work up, which includes ruling out retinoblastoma. CSD can present as a granulomatous mass similar to toxocariasis, which can rarely lead to debilitating and irreversible vision. PMID- 29176528 TI - PARACENTRAL ACUTE MIDDLE MACULOPATHY IN A PERIVENULAR FERN-LIKE DISTRIBUTION WITH EN FACE OPTICAL COHERENCE TOMOGRAPHY. AB - PURPOSE: To report a case of central retinal vein occlusion resulting in a perivenular pattern of paracentral acute middle maculopathy lesions best identified with en face optical coherence tomography (OCT). METHODS: Retrospective case report. Optos ultra-widefield fluorescein angiography, spectral domain OCT, en face OCT, and OCT angiography were performed. RESULTS: A 41-year-old man presented with decreased vision in the right eye for 2 weeks. Funduscopic examination of the affected right eye was notable for subtle retinal whitening in the macula, mild retinal venous dilation and tortuosity, and few scattered retinal dot and blot hemorrhages consistent with an acute central retinal vein occlusion. Widefield fluorescein angiography demonstrated delayed arterial and venous filling but no evidence of significant peripheral retinal vascular ischemia. En face OCT segmented at the inner nuclear layer illustrated a remarkable and precise perivenular distribution of fern-like paracentral acute middle maculopathy with periarterial sparing, whereas en face OCT segmented at the outer nuclear layer demonstrated florid cystoid macular edema. At 6-week follow-up, OCT demonstrated patchy areas of atrophic inner nuclear layer and spontaneous resolution of the cystoid macular edema. Optical coherence tomography angiography at the level of the deep capillary plexus illustrated remarkable flow reduction of the deep capillary plexus in mainly a perivenular distribution. CONCLUSION: The authors report a case of a central retinal vein occlusion with mild retinal findings associated with a remarkable perivenular pattern of paracentral acute middle maculopathy with en face OCT. Follow-up OCT angiography demonstrated significant flow reduction of the deep capillary plexus in a perivenular pattern. The perivenular pattern of paracentral acute middle maculopathy lesions with en face OCT can be an important finding suggestive of a central retinal vein occlusion. PMID- 29176529 TI - ATYPICAL PERIPAPILLARY INNER RETINOSCHISIS IN STELLATE NONHEREDITARY IDIOPATHIC FOVEOMACULAR RETINOSCHISIS. AB - PURPOSE: To describe an atypical presentation of a patient with stellate nonhereditary idiopathic foveomacular retinoschisis with peripapillary retinoschisis of multiple layers. METHODS: Complete ophthalmic examination including dilated extended ophthalmoscopy, fluorescein angiography, optical coherence tomography, optical coherence tomography angiography, and wide-field fundus photography. RESULTS: A 36-year-old Chinese American woman with mild myopia and good visual acuity (20/20) exhibited macular splitting of the outer plexiform layer on spectral domain optical coherence tomography with an attached hyaloid in her left eye. Peripheral spectral domain optical coherence tomography also demonstrated peripapillary and midperipheral inner retinoschisis, involving the outer plexiform layer and inner retina. The right eye was unremarkable. The diagnosis of stellate nonhereditary idiopathic foveomacular retinoschisis was made because of a lack of other associated ocular conditions and no family history of retinoschisis. CONCLUSION: Stellate nonhereditary idiopathic foveomacular retinoschisis is a recently described and uncommon cause of foveomacular retinoschisis in myopic women with good visual acuity. Recent evidence suggests that peripheral imaging is key in identifying other findings, including midperipheral or peripapillary inner retinoschisis, involving the outer plexiform layer and the inner retina. Our patient may represent a variant of stellate nonhereditary idiopathic foveomacular retinoschisis that can be characterized by multilayer peripapillary retinoschisis. PMID- 29176530 TI - A 9-YEAR-OLD GIRL WITH ACUTE MACULAR NEURORETINOPATHY. AB - PURPOSE: To report the clinical findings of the youngest confirmed case of acute macular neuroretinopathy to the best of our knowledge. METHODS: A 9-year-old patient describing a paracentral scotoma with a normal clinical examination and normal fluorescein angiography. RESULTS: Initial fundus examination was unremarkable. Fluorescein angiography findings showed no abnormalities but scotoma was confirmed using Amsler grid. Optical coherence tomography showed a parafoveal hyperreflective band in the outer layers. Subsequent optical coherence tomography showed resolution of the pathology. CONCLUSION: Acute macular neuroretinopathy is a rare condition usually presented as paracentral scotomas. Optical coherence tomography and Amsler grid testing can be used for diagnosis and to monitor findings on follow-up until resolution. PMID- 29176532 TI - PARANEOPLASTIC VITELLIFORM MACULOPATHY ASSOCIATED WITH METASTATIC MELANOMA. AB - PURPOSE: To report a case of paraneoplastic vitelliform maculopathy in a patient with metastatic melanoma of unknown primary site. METHODS: Case report. Main outcome measures include funduscopic examination, fluorescein angiography, fundus autofluorescence, and spectral domain optical coherence tomography. RESULTS: A 44 year-old man with a known history of metastatic melanoma was referred for ophthalmic evaluation because of bilateral vision loss. Funduscopic examination was remarkable for vitelliform maculopathy that was confirmed with fundus autofluorescence and spectral domain optical coherence tomography. CONCLUSION: We describe a rare case of paraneoplastic vitelliform maculopathy. There are many etiologies of acquired vitelliform retinal lesions in the retina. Multimodal retinal imaging, including fundus autofluorescence and spectral domain optical coherence tomography, can be best used to identify these lesions. A history of systemic metastatic melanoma should be ruled out in patients with vitelliform maculopathy. PMID- 29176531 TI - AUTOIMMUNE RETINOPATHY IN A PATIENT WITH A MISSENSE MUTATION IN PITPNM3. AB - PURPOSE: To describe a patient with a PITPNM3 missense mutation who developed late-onset autoimmune retinopathy. METHODS: Case report. RESULTS: An 85-year-old man presented with decreased vision, nyctalopia, and photoaversion after an uncomplicated cataract surgery. Multimodal retinal imaging revealed a scalloped pattern of atrophy and a ring of hyperautofluorescence in the perifoveal area on fundus autofluorescence. Spectral domain optical coherence tomography demonstrated loss of the ellipsoid band, along with outer retinal atrophy, sparing the fovea in both eyes. Full field electroretinogram revealed extinguished rod response and severely attenuated cone response. Antiretinal antibodies to 20-kDa and 125-kDa proteins were detected. Whole-exome sequencing revealed a heterozygous variant, c.2579T>C, p.(Ile860Thr) in PITPNM3, predicted to be severely damaging and deleterious to the protein structure and function. Over the course of 3 months, the patient experienced a rapid progression. Neoplastic workup was negative and he was started on immunosuppressive therapy for a presumed diagnosis of nonparaneoplastic autoimmune retinopathy. CONCLUSION: To the authors' knowledge, this is the first report of autoimmune retinopathy in a patient with PITPNM3 mutation. PITPNM3 has been previously shown to affect regulatory T cell function. PMID- 29176533 TI - IDIOPATHIC MULTIFOCAL CHOROIDITIS PRESENTING WITH A TRANSIENT PERIPAPILLARY WHITE RING. AB - PURPOSE: We describe with multimodal imaging the presentation and follow-up for a patient with idiopathic multifocal choroiditis and a transient peripapillary white ring. METHODS: Case report. RESULTS: A 39-year-old Asian woman was initially seen for an evaluation of lattice degeneration in 2015. Her medical history included Graves disease and psoriasis. Best-corrected visual acuity was 20/25 in her right eye and 20/25 in her left eye. Ultra-widefield fundus autofluorescence imaging showed a curvilinear hyperautofluorescent line in her right eye. One year later, the patient returned complaining of floaters in her right eye for 1 month. Her visual acuity was unchanged. Funduscopic examination showed new inflammatory yellowish lesions in the right eye corresponding to hyperreflective sub-retinal pigment epithelium lesions on structural spectral domain optical coherence tomography. Fluorescein angiography showed corresponding late staining of these active lesions. Late-phase indocyanine green angiography showed multiple nummular hypocyanescent dots. Ultra-widefield fundus autofluorescence showed large areas of hyperautofluorescence. The patient was started on a 60-mg oral prednisone taper and demonstrated subsequent regression of the inflammatory lesions. Ten months later, the patient returned emergently with complaints of floaters in both eyes for 2 days and a new temporal scotoma in her left eye. Funduscopic examination demonstrated a white ring around the optic nerve of the left eye corresponding to a hyperautofluorescent lesion. Ultra widefield fundus autofluorescence showed new areas of hyperautofluorescence in both eyes. Structural spectral domain optical coherence tomography showed new sub retinal pigment epithelium inflammatory lesions and a disruption of the ellipsoid zone in both eyes. The patient was again treated with a 60-mg oral prednisone taper and demonstrated subsequent restoration of the ellipsoid zone. CONCLUSION: To our knowledge, this is the first report of a transient annular white ring occurring in a case of multifocal choroiditis. There was marked restoration of the disrupted ellipsoid zone after treatment with oral corticosteroids. PMID- 29176534 TI - IMMUNE RETINOPATHY ASSOCIATED WITH NIVOLUMAB ADMINISTRATION FOR METASTATIC NON SMALL CELL LUNG CANCER. AB - PURPOSE: To present a novel case of immune retinopathy associated with nivolumab therapy for non-small cell lung cancer. METHODS: Retrospective chart review. RESULTS: A 64-year-old woman presented with photoreceptor injury evidenced by hypoautofluorescent and hyperautofluorescent patches on fundus autofluorescence, loss of the ellipsoid zone on optical coherence tomography, and dysfunction of the rods and cones on electroretinogram. She had a history of Stage IV lung adenocarcinoma, treated with nivolumab, a checkpoint inhibitor. Serology testing was negative for paraneoplastic antibody panel, antirecoverin and antienolase antibodies, but positive for antiretinal antibodies against 30-kDa (carbonic anhydrase II), 35-kDa (GADPH), 38-kDA, 58-kDa (PKM2), and 112-kDa proteins. Cessation of the medication and high-dose oral steroids resulted in resolution of her symptoms and stability of ocular findings. CONCLUSION: The checkpoint inhibitors, including nivolumab, have significant ocular side effects. All patients receiving nivolumab should undergo a baseline comprehensive eye examination and should be counseled to seek medical attention immediately if visual changes occur. PMID- 29176535 TI - SPONTANEOUS IMPROVEMENT OF SYPHILIS CHORIORETINITIS: CASE REPORT AND REVIEW OF THE LITERATURE. AB - PURPOSE: To describe a case of spontaneous improvement of syphilis chorioretinitis and review the literature. METHODS: Case report and literature review of cases with untreated syphilis chorioretinitis. RESULTS: A 58-year-old man presented to the emergency department with counting fingers vision, normal fundus, and disruption of the outer retinal layers on optical coherence tomography of the right eye. Examination by a retina specialist 3 weeks later revealed visual acuity of 20/50 and partial restoration of outer retinal layers on optical coherence tomography. Workup showed positive serology for syphilis and human immunodeficiency virus. Treatment with intravenous penicillin resulted in further vision improvement. Literature review showed six cases of spontaneous improvement of syphilis chorioretinitis. CONCLUSION: Spontaneous improvement of syphilis chorioretinitis is possible. Clinicians should keep a high index of suspicion and consider syphilis chorioretinitis in diseases that affect the outer retina even with spontaneous improvement. PMID- 29176536 TI - PARACENTRAL ACUTE MIDDLE MACULOPATHY ASSOCIATED WITH BILATERAL OPTIC DISK SWELLING AND MENINGITIS. AB - BACKGROUND/PURPOSE: To present a novel case of paracentral acute middle maculopathy associated with bilateral optic disk swelling. METHODS: Retrospective case report. RESULTS: A 67-year-old woman presented with sudden onset of central vision loss and subsequent bilateral optic disk edema, retinal vessel attenuation, and anterior uveitis. Cerebrospinal fluid analysis showed signs of inflammation. Spectral domain optical coherence tomography demonstrated the pathognomonic hyperreflectivity of the middle retinal layers consistent with paracentral acute middle maculopathy. Swept-source optical coherence tomography angiography with custom vessel analysis demonstrated a 18.3% decrease in the deep retinal vascular density and 2.4 times increase in absent flow area in the affected eye compared with the fellow eye. CONCLUSION: This case demonstrates a novel association between paracentral acute middle maculopathy and bilateral optic disk swelling secondary to central nervous system inflammation and possible infection. Although spectral domain optical coherence tomography is valuable in detecting paracentral acute middle maculopathy, optical coherence tomography angiography with vessel analysis can provide additional insight into the disease mechanism. PMID- 29176537 TI - NOVEL SURGICAL TECHNIQUE FOR INDUCING POSTERIOR VITREOUS DETACHMENT DURING PARS PLANA VITRECTOMY FOR PEDIATRIC PATIENTS USING A FLEXIBLE LOOP. AB - PURPOSE: Vitreoretinal surgical diseases in children are challenging because of the complex features of the vitreous, retina, and the interface between them. Posterior vitreous detachment is a crucial step during vitrectomy. To date, pharmacologic vitreolysis that liquefies the vitreous and disrupts the posterior hyaloid attachment to the retina has been studied. However, there are reports of unexplained adverse effects. We describe a case performed with a reproducible, safe and time-saving technique using a commercially available flexible loop for posterior vitreous detachment induction in a pediatric patient. METHODS: A 10 year-old boy with previously treated retinopathy of prematurity undergoes a 25 gauge pars plana vitrectomy for retina detachment repair. To achieve a posterior vitreous detachment, a flexible loop was used to grasp and pick the vitreoretinal interface around the optic nerve for dissection of the posterior hyaloid, followed by aspiration and cutting with the vitrectomy probe to complete the vitrectomy. RESULTS: At 3 months follow-up, total retinal reattachment was observed. The patient's vision improved from 20/400 to 20/150. CONCLUSION: Posterior vitreous detachment induction with a flexible loop instead of pharmacologic vitreolysis seems a promising tool as demonstrated in this clinical case. Further studies to demonstrate long-term safety and anatomical results are needed. PMID- 29176538 TI - VITREOUS TREPONEMAL ANTIBODY AS A SUPPLEMENTARY TEST TO SEROLOGY FOR THE CONFIRMATION OF SYPHILITIC CHORIORETINITIS. AB - PURPOSE: To report the novel application of nontreponemal and treponemal antibody to confirm diagnosis of ocular syphilis from vitreous samples. METHODS: Two distinct case reports emphasizing the importance of confirmatory vitreous treponemal antibody. Multimodal imaging of patients was also applied. RESULTS: We report two distinct cases with positive serum treponemal antibody but opposing vitreous treponemal antibody results. One case with a positive vitreous test responded well to antisyphilitic treatment. By contrast, a case with a negative vitreous result was changed to serpiginous choroiditis, eventually cured by immunomodulatory treatment. CONCLUSION: Intraocular fluid analysis of nontreponemal and treponemal antibody may play an important role in ruling out suspected ocular syphilis in settings without a polymerase chain reaction facility, especially immunocompromised patients who are at risk of multiple infections. Further studies are needed to establish the sensitivity and specificity of nontreponemal and treponemal antibody test on vitreous samples. PMID- 29176539 TI - Efficacy and Safety of Chemotherapy Combined with Stereotactic Radiotherapy in the Treatment of Nasopharyngeal Carcinoma. AB - BACKGROUND The aim of this study was to investigate the efficacy and safety of chemotherapy (CT) combined with stereotactic radiotherapy (SRT) in the treatment of nasopharyngeal carcinoma (NPC). MATERIAL AND METHODS A total of 329 NPC patients without any previous treatment were included in this study between January 2009 and November 2013. These patients were divided into three groups: CT group (n=114), SRT group (n=109), and CT + SRT group (n=106). Contrast-enhanced nasopharyngeal computed tomography (CT)/magnetic resonance (MR) scan was performed on the third month after treatment. Short-term efficacy was evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST). Toxicity was graded according to the Acute Radiation Morbidity Scoring Criteria (RTOG) and the World Health Organization (WHO) toxicity grading scale. Overall survival (OS), progression free survival (PFS), and incidence rate of acute toxicity (grade >=3) were calculated after a 24 month follow-up. RESULTS Total response rate of all patients was 85.41%. Compared with the CT group and the SRT group, the CT + SRT group showed a substantially improved efficacy in NPC treatment. The incidence rate of the acute toxicity in the CT + SRT group was slightly higher than in the CT group and the SRT group, but the difference was not statistically significant. No treatment-related deaths were observed. The CT + SRT group had the highest two-year OS and PFS, followed by the CT group and the SRT group. CONCLUSIONS It was shown that NPC patients treated with CT + SRT had better short and long-term efficacy than those treated with CT or SRT alone. PMID- 29176540 TI - The Effect of Oral Contraceptive Pills on the Macula, the Retinal Nerve Fiber Layer, and Choroidal Thickness. AB - BACKGROUND The aim of this study was to evaluate the effect of oral contraceptive pills (OCP) on the macula, the retinal nerve fiber layer (RNFL), and choroidal thickness (CT). MATERIAL AND METHODS A total of 24 healthy women taking monophasic OCP (3 mg drospirenone and 0.03 mg ethinylestradiol) for contraception only for at least one year were compared with a control group of 24 healthy women who were not taking an OCP. Optical coherence tomography (OCT) was used to evaluate the posterior ocular segments, and measurements were taken in the follicular phase (day 3) of the cycle in all women. RESULTS No disparity in terms of age and body mass index between the groups was observed (p=0.436, p=0.538, respectively). In comparison of the macular region and CT between groups, we found that all variables except foveal center thickness and CT were significantly thinner in the OCP group. Nasal and temporal inferior parts of the RNFL and average RNFL were significantly slimmer in the study group versus the control group (p=0.013, p=0.018, and p<0.001, respectively). CONCLUSIONS OCP resulted in several structural changes in the posterior ocular segment. Thus, women using OCP for more than one year may have some eye problems. Therefore, it OCT should be performed for these women. Further clinical trials researching long-period effect of OCP on the eyes are needed. PMID- 29176541 TI - Diffuse Peritoneal and Bowel Wall Infiltration by Light Chain-AL Amyloidosis with Omental Calcification Mimicking Abdominal Carcinomatosis - An Elderly Female with Incidental Finding of Light Chain Monoclonal Gammopathy of Undetermined Significance (LC-MGUS). AB - BACKGROUND Amyloidosis is the extracellular tissue deposition of plasma proteins, which after conformational changes, forms antiparallel beta pleated sheets of fibrils. Amyloid light-chain (AL) is a type of amyloidosis that is due to deposition of proteins derived from immunoglobulin (Ig) light chains. Gastrointestinal tract (GIT) involvement most often found in amyloid A (AA) amyloidosis type. There have been no reports of obstructive GIT AL amyloid patients having monoclonal gammopathy of undetermined significance (MGUS). Our case is the first case to show two coinciding conditions; one is the association of GIT AL amyloidosis with the incidental finding of a rare type of MGUS (LC MGUS) and the other is the radiologic presentation of GIT amyloidosis with omental calcification mimicking the GIT malignancy. CASE REPORT A 68-year-old female presented with symptoms of partial bowel obstruction, including intermittent diffuse abdominal pain and constipation. After computed tomography (CT) abdomen and pelvis, an exploratory laparotomy was needed because of suspicion of abdominal carcinomatosis due to diffuse omental calcification. The tissue sent for biopsy surprisingly showed AL amyloidosis. The patient did not report any systemic symptoms. Further workup was advised to inquire about the plasma cell dyscrasia which eventually turned into a very rare version of MGUS knows as light chain MGUS (LC-MGUS). Following adequate resection of the involved structures, the patient was then placed on chemotherapy and successfully went into remission. CONCLUSIONS This case report illustrates that in an era of evidence based medicine, it is important to show through case reports the association of GIT AL amyloidosis with LC-MGUS, as the literature on this topic is lacking. It also points to the importance of timely intervention that can greatly enhance, not only the only the chances of remission but also prevention of further complications such as malignant transformation. PMID- 29176542 TI - Diabetic Microagiopathy of Oral Mucosa Depends on Disease Duration and Therapy. AB - BACKGROUND Diabetes mellitus is a chronic degenerative systemic disease whose prevalence is increasing. This paper aims to evaluate the effects of diabetic microangiopathy, depending on its duration and the type of treatment administered, by using polarized light videocapillaroscopy of the oral mucosa. MATERIAL AND METHODS We enrolled 120 subjects: 60 healthy subjects and 60 patients with diabetes mellitus. In turn, patients were divided into 3 subgroups according to the type of diabetes, the duration of the disease, and the type of treatment administered. A videocapillaroscopic examination of the oral mucosa was carried out on the diabetic and healthy subjects. RESULTS Changes in microcirculation were detected in diabetic patients: at the level of the labial, buccal, and lingual mucosa, the density of the loops is on average reduced; there is an increase in the length and the total diameter of the loops, while the average density of the periodontal capillaries is much higher. The most significant changes were noted in patients who had had type 1 diabetes for more than 10 years and had received insulin therapy. CONCLUSIONS This study, performed using polarized light videocapillaroscopy, which for the first time was used to analyze the capillaries of the oral mucosa in patients with diabetes, confirms the presence of changes that are instrumentally "objectifiable" and "quantifiable" through the videocapillaroscopic technique. Videocapillaroscopy can be a reliable method in the study and monitoring of complications in patients with type 1 and 2 diabetes mellitus. PMID- 29176543 TI - A Rare Case of Cerebellar Ataxia Due to Voltage-Gated Calcium Channel and Glutamic Acid Decarboxylase Autoantibodies. AB - BACKGROUND Autoimmune cerebellar ataxia can be paraneoplastic in nature or can occasionally present without evidence of an ongoing malignancy. The detection of specific autoantibodies has been statistically linked to different etiologies. CASE REPORT A 55-year-old African-American woman with hypertension and a past history of morbid obesity and uncontrolled diabetes status post gastric bypass four years prior to the visit (with significantly improved body mass index and hemoglobin A1c controlled at the time of the clinical encounter) presented to the office complaining of gradual onset of unsteadiness and recurrent falls for the past three years, as well as difficulties coordinating routine daily activities. The neurologic exam showed moderate dysarthria and ataxic gait with bilateral dysmetria and positive Romberg test. Routine laboratory test results were only remarkable for a mild elevation of erythrocyte sedimentation rate, and most laboratory and imaging tests for common causes of ataxia failed to demonstrate an etiology. Upon further workup, evidence of anti-voltage-gated calcium channel and anti-glutamic acid decarboxylase antibody was demonstrated. She was then treated with intravenous immunoglobulins with remarkable clinical improvement. CONCLUSIONS We present a case of antibody-mediated ataxia not associated with malignancy. While ataxia is rarely related to autoantibodies, in such cases it is critical to understand the etiology of this disabling condition in order to treat it correctly. Clinicians should be aware of the possible association with specific autoantibodies and the necessity to rule out an occult malignancy in such cases. PMID- 29176544 TI - PI3K-Akt Signal Transduction Molecules Maybe Involved in Downregulation of Erythroblasts Apoptosis and Perifosine Increased Its Apoptosis in Chronic Mountain Sickness. AB - BACKGROUND Chronic mountain sickness (CMS) has a higher incidence in the plateau region. The one of its principal characters is excessive erythrocytosis. The PI3K Akt pathway plays an important role in the process of erythropoiesis, and could downregulate apoptosis by regulating apoptosis-related molecules. In this paper, we explored the change in apoptosis of erythroblasts and the effect of the PI3K Akt signal pathway on erythroblasts apoptosis in CMS. MATERIAL AND METHODS A total of 22 CMS and 20 non-CMS participants were involved in this study. Bone marrow mononuclear cells were cultured and treated with celecoxib and perifosine in vitro for 72 hours. The apoptotic rate, the mRNA expressions of Akt, Bcl-xl, and caspase-9, and the protein expressions of Akt, p-Akt, Bcl-xl, and caspase-9 were determined by flow cytometry, quantitative RT-PCR, and western-blot technique. RESULTS The apoptotic rate of cultured erythroblasts was lower in the CMS group than in the non-CMS group. It was increased after perifosine intervention. The mRNA and protein expressions of Akt and Bcl-xl were higher and caspase-9 was lower in the CMS group than the non-CMS group. Perifosine induced decreased Bcl-xl mRNA and proteins and p-Akt proteins, and increased caspase-9 mRNA and proteins in vitro. In the CMS group, the hemoglobin concentration was correlated with apoptotic rate negatively and with Bcl-xl mRNA positively in erythroblasts; the erythroblasts apoptotic rate was negatively associated with the Akt mRNA and Bcl-xl mRNA. CONCLUSIONS The erythroblasts apoptosis was downregulated and the PI3K-Akt signal pathway appeared to be involved in the mechanism of decreased erythroblasts apoptosis in CMS.

AB - BACKGROUND Multivariate models with a combination of variables can predict disease more accurately than a single variable employed alone. We developed a logistic regression model with a combination of variables and evaluated its ability to predict lung cancer. MATERIAL AND METHODS The exhaled breath from 57 patients with lung cancer and 72 healthy controls without cancer was collected. The VOCs of exhaled breath were examined qualitatively and quantitatively by a novel electronic nose (Z-nose4200 equipment). The VOCs in the 2 groups were compared using the Mann-Whitney U test, and the baseline data were compared between the 2 groups using the chi-square test or ANOVA. Variables from VOCs and baseline data were selected by stepwise logistic regression and subjected to a prediction model for the diagnosis of lung cancer as combined factors. The receiver operating characteristic (ROC) curve was used to evaluate the predictive ability of this prediction model. RESULTS Nine VOCs in exhaled breath of lung cancer patients differed significantly from those of healthy controls. Four variables - age, hexane, 2,2,4,6,6-pentamethylheptane, and 1,2,6 trimethylnaphthalene - were entered into the prediction model, which could effectively separate the lung cancer samples from the control samples with an accuracy of 82.8%, a sensitivity of 76.0%, and a specificity of 94.0%. CONCLUSIONS The profile of VOCs in exhaled breath contained distinguishable biomarkers in the patients with lung cancers. The prediction model with 4 variables appears to provide a new technique for lung cancer detection.

AB - BACKGROUND Migration of leukocytes into airways is the hallmark of allergic asthma. The aim of this study was to target the pathological process using pantethine, a pleiotropic natural compound which has been recently shown to down regulate chemokine-driven T cell migration. MATERIAL AND METHODS Mice were sensitized to the Leishmania LACK antigen, then treated or not treated with pantethine and exposed to LACK or saline aerosol. After sacrifice of the animals, cells in the bronchoalveolar lavage were analyzed and inflammatory parameters were determined to evaluate inflammation seriousness. RESULTS As compared to untreated animals, pantethine-treated animals displayed a moderated response to the allergen, as documented by decreased infiltration of inflammatory cells (all types), in addition to reduced levels of lung Th2 cytokines and circulating LACK specific IgE. CONCLUSIONS These data reveal the potential therapeutic importance of pantethine to moderate allergic asthma pathology. The compound has been previously shown to exert a broad range of protective activity in animals and in humans, with few or no adverse effects. PMID- 29176547 TI - Protective Role of TNIP2 in Myocardial Injury Induced by Acute Pancreatitis and Its Mechanism. AB - BACKGROUND Aberrant regulation of nuclear factor-kappaB (NF-kappaB) and the signaling pathways that regulate its activity have been found to be involved in various pathologies, particularly cancers, as well as inflammatory and autoimmune diseases. Acute pancreatitis (AP) is a complex pathological process, depending on autodigestion caused by premature activation of zymogens. This study aimed to investigate the effect of high expression of TNIP2 gene on AP and AP-induced myocardial injury. MATERIAL AND METHODS To investigate the effect of TNIP2 on AP and AP-induced myocardial injury, we established an AP cell model and rat model. HE staining was applied for histological examination. ELISA was used to determine the level of pro-inflammatory cytokines (TNF-alpha and IL-6) and myocardial injury markers (LDH and CK-MB). QRT-PCR and Western blot analysis were performed to determine the mRNA and protein level of related genes, respectively. RESULTS We found that the protein level of TNIP2 was relatively higher in the normal AR42J cells. At 4 h after stimulating with cerulein, the protein level of TNIP2 decreased, reached a minimum at 8 h, and then gradually increased. We also found that TNIP2 was correlated with the activation of NF-kappaB in cerulein-stimulated AR42J cells, and TNIP2 over-expression inhibited the inflammatory response caused by cerulein. Moreover, our results suggest that TNIP2 over-expression relieved the cerulein-triggered inflammatory response and AP-induced myocardial injury in mice. CONCLUSIONS TNIP2 was shown to exert a protective effect on AP and AP induced myocardial injury. PMID- 29176548 TI - Comparison through a prospective and randomized study of two replenishment methods at polyvalent hospitalization units with two-bin storage systems AB - OBJECTIVE: Two-bin storage systems increase nursing staff satisfaction and decrease inventories, but the implications that logistic staff would determine the needs of replenishment are unknown. This study aimed to evaluate whether entrust to logistics staff this responsibility at the polyvalent hospitalization units with two-bin storage is associated with higher risk of outstanding orders. METHODS: This was a prospective randomized experiment whit masking. Outstanding orders were considered variable response, those corresponding to assessments of the logistics staff were included in the control group and those corresponding to the nursing staff in the control group. Concordance between observers was analyzed using the Bland-Altman method; the difference between groups, with the U of Mann-Whitney and the cumulative incidence of outstanding orders and their relative risk was calculated. RESULTS: The mean amount requested by the logistic and nursing staff was 29.9 (SD:167.4) and 36 (SD:190) units respectively, the mean difference between observers was 6.11 (SD:128.95) units and no significant differences were found between groups (p = 0.430). The incidence of outstanding orders was 0.64% in the intervention group and 0.15% in the control group; the relative risk, 2.31 (0.83 - 6.48) and the number of cases required for an outstanding order, 516. CONCLUSIONS: Outstanding order relative risk is not associated with the category of the staff that identifies the replenishment needs at the polyvalent hospitalization units.

AB - Digital image sensors in hemispherical geometries offer unique imaging advantages over their planar counterparts, such as wide field of view and low aberrations. Deforming miniature semiconductor-based sensors with high-spatial resolution into such format is challenging. Here we report a simple origami approach for fabricating single-crystalline silicon-based focal plane arrays and artificial compound eyes that have hemisphere-like structures. Convex isogonal polyhedral concepts allow certain combinations of polygons to fold into spherical formats. Using each polygon block as a sensor pixel, the silicon-based devices are shaped into maps of truncated icosahedron and fabricated on flexible sheets and further folded either into a concave or convex hemisphere. These two electronic eye prototypes represent simple and low-cost methods as well as flexible optimization parameters in terms of pixel density and design. Results demonstrated in this work combined with miniature size and simplicity of the design establish practical technology for integration with conventional electronic devices. PMID- 29176551 TI - Discovery of novel choline acetyltransferase inhibitors using structure-based virtual screening. AB - Alzheimer disease and related dementias are major challenges, demanding urgent needs for earliest possible diagnosis to optimize the success rate in finding effective therapeutic interventions. Mounting solid scientific premises point at the core acetylcholine-biosynthesizing cholinergic enzyme, ChAT as a legitimate in vivo target for developing positron emission tomography biomarker for early diagnosis and/or monitoring therapeutic responses in the neurodegenerative dementias. Up-to-date, no PET tracer ligands for ChAT are available. Here we report for the first time a novel hierarchical virtual screening approach on a commercial library of ~300,000 compounds, followed by in vitro screening of the hits by a new High-Throughput ChAT assay. We report detailed pharmacodynamic data for three identified selective novel ChAT ligands with IC50 and K i values ranging from ~7 to 26 uM. In addition, several novel selective inhibitors of the acetylcholine-degrading enzymes, AChE and BuChE were identified, with one of the compounds showing an IC50-value of ~6 uM for AChE. In conclusion, this report provides an excellent starting platform for designing and optimizing potent and selective ChAT ligands, with high potential as PET-imaging probe for early diagnosis of AD, and related dementias, such as Down's syndrome and Lewy body disorders. PMID- 29176550 TI - A bioreducible N-oxide-based probe for photoacoustic imaging of hypoxia. AB - Hypoxia occurs when limited oxygen supply impairs physiological functions and is a pathological hallmark of many diseases including cancer and ischemia. Thus, detection of hypoxia can guide treatment planning and serve as a predictor of patient prognosis. Unfortunately, current methods suffer from invasiveness, poor resolution and low specificity. To address these limitations, we present Hypoxia Probe 1 (HyP-1), a hypoxia-responsive agent for photoacoustic imaging. This emerging modality converts safe, non-ionizing light to ultrasound waves, enabling acquisition of high-resolution 3D images in deep tissue. HyP-1 features an N oxide trigger that is reduced in the absence of oxygen by heme proteins such as CYP450 enzymes. Reduction of HyP-1 produces a spectrally distinct product, facilitating identification via photoacoustic imaging. HyP-1 exhibits selectivity for hypoxic activation in vitro, in living cells, and in multiple disease models in vivo. HyP-1 is also compatible with NIR fluorescence imaging, establishing its versatility as a multimodal imaging agent. PMID- 29176552 TI - Hall conductance for open two-band system beyond rotating-wave approximation. AB - The response of the open two-band system to external fields would in general be different from that of a strictly isolated one. In this paper, we systematically study the Hall conductance of a two-band model under the influence of its environment by treating the system and its environment on equal footing. In order to clarify some well-established conclusions about the Hall conductance, we do not use the rotating wave approximation (RWA) in obtaining an effective Hamiltonian. Specifically, we first derive the ground state of the whole system (the system plus the environment) beyond the RWA, then calculate an analytical expression for Hall conductance of this open system in the ground state. We apply the expression to two examples, including a magnetic semiconductor with Rashba type spin-orbit coupling and an electron gas on a square two-dimensional lattice. The calculations show that the transition points of topological phase are robust against the environment. Our results suggest a way to the controlling of the whole system response, which has potential applications for condensed matter physics and quantum statistical mechanics. PMID- 29176553 TI - Notoginsenoside R1 Alleviates Oxygen-Glucose Deprivation/Reoxygenation Injury by Suppressing Endoplasmic Reticulum Calcium Release via PLC. AB - As documented in our previous study, notoginsenoside R1 (NGR1) can inhibit neuron apoptosis and the expression of endoplasmic reticulum (ER) stress-associated pro apoptotic proteins in hypoxic-ischemic encephalopathy. Recent evidence indicates that the Phospholipase C (PLC)/inositol 1,4,5-trisphosphate receptor (IP3R) is important for the regulation of Ca2+ release in the ER. Ca2+ imbalance can stimulate ER stress, CAMKII, and cell apoptosis. The purpose of this study was to further investigate the neuroprotective effect of NGR1 and elucidate how NGR1 regulates ER stress and cell apoptosis in the oxygen-glucose deprivation/reoxygenation (OGD/R) model. Cells were exposed to NGR1 or the PLC activator m-3M3FBS. Then, IP3R- and IP3-induced Ca2+ release (IICR) and activation of the ER stress and CaMKII signal pathway were measured. The results showed that NGR1 inhibited IICR and strengthened the binding of GRP78 with PERK and IRE1. NGR1 also alleviated the activation of the CaMKII pathway. Pretreatment with m-3M3FBS attenuated the neuroprotective effect of NGR1; IICR was activated, activation of the ER stress and CaMKII pathway was increased, and more cells were injured. These results indicate that NGR1 may suppress activation of the PLC/IP3R pathway, subsequently inhibiting ER Ca2+ release, ER stress, and CaMKII and resulting in suppressed cell apoptosis. PMID- 29176554 TI - Membrane insertion of the BAX core, but not latch domain, drives apoptotic pore formation. AB - Despite intensive research effort, how the paradigmatic proapoptotic protein BAX forms lethal apoptotic pores at the mitochondrial outer membrane (MOM) remains incompletely understood. Here, we used biophysical tools and minimalist model systems to identify the specific regions in BAX driving apoptotic pore formation, and to gain more insight into underlying mechanisms. Fluorescence mapping revealed that fully active BAX adopts a BH3-in-groove dimeric conformation in MOM like membranes, with BAX alpha4-alpha5 helices belonging to its core domain inserting deeper into the membrane lipid bilayer than BAX alpha6-alpha8 helices belonging to its latch domain. In our reconstituted systems, antiapoptotic BCLXL formed canonical heterodimeric BH3-in-groove complexes with BAX, and blocked membrane insertion of BAX core alpha4-alpha5 helices, but not BAX latch alpha6 alpha8 helices. Moreover, poly(ethylene glycol) (PEG) conjugation (PEGylation) at multiple individual sites along the BAX core, but not latch domain, potently inhibited BAX pore-forming activity. Additional combined computational and experimental evidence revealed that the BAX core alpha5 helix displays a bilayer destabilizing membrane interaction mode that is absent in BAX latch alpha6-alpha8 helices. Based on this collective set of evidence, we propose that membrane insertion of the BAX core, but not latch domain, is critical for BAX apoptotic pore formation. PMID- 29176555 TI - Hydrogen mobility in the lightest reversible metal hydride, LiBeH3. AB - Lithium-beryllium metal hydrides, which are structurally related to their parent compound, BeH2, offer the highest hydrogen storage capacity by weight among the metal hydrides (15.93 wt. % of hydrogen for LiBeH3). Challenging synthesis protocols have precluded conclusive determination of their crystallographic structure to date, but here we analyze directly the hydrogen hopping mechanisms in BeH2 and LiBeH3 using quasielastic neutron scattering, which is especially sensitive to single-particle dynamics of hydrogen. We find that, unlike its parent compound BeH2, lithium-beryllium hydride LiBeH3 exhibits a sharp increase in hydrogen mobility above 265 K, so dramatic that it can be viewed as melting of hydrogen sublattice. We perform comparative analysis of hydrogen jump mechanisms observed in BeH2 and LiBeH3 over a broad temperature range. As microscopic diffusivity of hydrogen is directly related to its macroscopic kinetics, a transition in LiBeH3 so close to ambient temperature may offer a straightforward and effective mechanism to influence hydrogen uptake and release in this very lightweight hydrogen storage compound. PMID- 29176556 TI - Recognition of a likely two phased extinction at the K-Pg boundary in Antarctica. AB - The southernmost Cretaceous - Paleogene (K-Pg) outcrop exposure is the well studied exposure on Seymour Island, Antarctica. Deposition across the K-Pg boundary there is uninterrupted, and as a consequence the ammonite fossil record is commonly used to test statistical methods of evaluating mass extinctions to account for the incompleteness of the fossil record. Numerous detailed fossil data sets from Seymour Island, comprised dominantly of mollusks, have been published over the last 30 years, but in most cases have not received statistical treatment. Here a previously published statistical technique is modified, automated, and applied to all published macrofossil data sets available from Seymour Island. All data sets reveal likely evidence of two separate multi species extinctions, one synchronous with bolide impact evidence at the K-Pg boundary, and another 45 +/- 15 meters (~140-290 ky) below the boundary. The apparent earlier extinction primarily affects benthic mollusks, while the boundary extinction primarily affects ammonites. While there is no unique sedimentological change over the interval where the earlier extinction is identified, it is impossible to exclude the possibility that this pattern is stratigraphically controlled. The automation of this technique allows it to be applied easily to other large fossil data sets. PMID- 29176557 TI - Functional connectivity of the cortical network supporting statistical learning in musicians and non-musicians: an MEG study. AB - Statistical learning is a cognitive process of great importance for the detection and representation of environmental regularities. Complex cognitive processes such as statistical learning usually emerge as a result of the activation of widespread cortical areas functioning in dynamic networks. The present study investigated the cortical large-scale network supporting statistical learning of tone sequences in humans. The reorganization of this network related to musical expertise was assessed via a cross-sectional comparison of a group of musicians to a group of non-musicians. The cortical responses to a statistical learning paradigm incorporating an oddball approach were measured via Magnetoencephalographic (MEG) recordings. Large-scale connectivity of the cortical activity was calculated via a statistical comparison of the estimated transfer entropy in the sources' activity. Results revealed the functional architecture of the network supporting the processing of statistical learning, highlighting the prominent role of informational processing pathways that bilaterally connect superior temporal and intraparietal sources with the left IFG. Musical expertise is related to extensive reorganization of this network, as the group of musicians showed a network comprising of more widespread and distributed cortical areas as well as enhanced global efficiency and increased contribution of additional temporal and frontal sources in the information processing pathway. PMID- 29176558 TI - Intraspecific variation and plasticity in mitochondrial oxygen binding affinity as a response to environmental temperature. AB - Mitochondrial function has been suggested to underlie constraints on whole organism aerobic performance and associated hypoxia and thermal tolerance limits, but most studies have focused on measures of maximum mitochondrial capacity. Here we investigated whether variation in mitochondrial oxygen kinetics could contribute to local adaptation and plasticity in response to temperature using two subspecies of the Atlantic killifish (Fundulus heteroclitus) acclimated to a range of temperatures (5, 15, and 33 degrees C). The southern subspecies of F. heteroclitus, which has superior thermal and hypoxia tolerances compared to the northern subspecies, exhibited lower mitochondrial O2 P50 (higher O2 affinity). Acclimation to thermal extremes (5 or 33 degrees C) altered mitochondrial O2 P50 in both subspecies consistent with the effects of thermal acclimation on whole organism thermal tolerance limits. We also examined differences between subspecies and thermal acclimation effects on whole-blood Hb O2-P50 to assess whether variation in oxygen delivery is involved in these responses. In contrast to the clear differences between subspecies in mitochondrial O2-P50 there were no differences in whole-blood Hb-O2 P50 between subspecies. Taken together these findings support a general role for mitochondrial oxygen kinetics in differentiating whole-organism aerobic performance and thus in influencing species responses to environmental change.

PMID- 29176560 TI - An activity-dependent proximity ligation platform for spatially resolved quantification of active enzymes in single cells. AB - Integration of chemical probes into proteomic workflows enables the interrogation of protein activity, rather than abundance. Current methods limit the biological contexts that can be addressed due to sample homogenization, signal-averaging, and bias toward abundant proteins. Here we report a platform that integrates family-wide chemical probes with proximity-dependent oligonucleotide amplification and imaging to quantify enzyme activity in native contexts with high spatial resolution. Application of this method, activity-dependent proximity ligation (ADPL), to serine hydrolase and cysteine protease enzymes enables quantification of differential enzyme activity resulting from endogenous changes in localization and expression. In a competitive format, small-molecule target engagement with endogenous proteins in live cells can be quantified. Finally, retention of sample architecture enables interrogation of complex environments such as cellular co-culture and patient samples. ADPL should be amenable to diverse probe and protein families to detect active enzymes at scale and resolution out of reach with current methods. PMID- 29176562 TI - Understanding heat patterns produced by vehicular flows in urban areas. AB - Vehicular traffic has strong implication in the severity and degree of Urban Heat Island (UHI) effect in a city. It is crucial to map and monitor the spatio temporal heat patterns from vehicular traffic in a city. Data observed from traffic counting stations are readily available for mapping the traffic-related heat across the stations. However, macroscopic models utilizing traffic counting data to estimate dynamic directional vehicular flows are rarely established. Our work proposes a simple and robust cell-transmission-model to simulate all the possible cell-based origin-destination trajectories of vehicular flows over time, based on the traffic counting stations. Result shows that the heat patterns have notable daily and weekly periodical circulation/pattern, and volumes of heat vary significantly in different grid cells. The findings suggest that vehicular flows in some places are the dominating influential factor that make the UHI phenomenon more remarkable. PMID- 29176561 TI - HIF drives lipid deposition and cancer in ccRCC via repression of fatty acid metabolism. AB - Clear cell renal cell carcinoma (ccRCC) is histologically defined by its lipid and glycogen-rich cytoplasmic deposits. Alterations in the VHL tumor suppressor stabilizing the hypoxia-inducible factors (HIFs) are the most prevalent molecular features of clear cell tumors. The significance of lipid deposition remains undefined. We describe the mechanism of lipid deposition in ccRCC by identifying the rate-limiting component of mitochondrial fatty acid transport, carnitine palmitoyltransferase 1A (CPT1A), as a direct HIF target gene. CPT1A is repressed by HIF1 and HIF2, reducing fatty acid transport into the mitochondria, and forcing fatty acids to lipid droplets for storage. Droplet formation occurs independent of lipid source, but only when CPT1A is repressed. Functionally, repression of CPT1A is critical for tumor formation, as elevated CPT1A expression limits tumor growth. In human tumors, CPT1A expression and activity are decreased versus normal kidney; and poor patient outcome associates with lower expression of CPT1A in tumors in TCGA. Together, our studies identify HIF control of fatty acid metabolism as essential for ccRCC tumorigenesis. PMID- 29176563 TI - Visualising the 3D microstructure of stained and native intervertebral discs using X-ray microtomography. AB - Intervertebral disc degeneration (IVDD) is linked to low back pain. Microstructural changes during degeneration have previously been imaged using 2D sectioning techniques and 3D methods which are limited to small specimens and prone to inducing artefacts from sample preparation. This study explores micro computed X-ray tomography (microCT) methods with the aim of resolving IVD 3D microstructure whilst minimising sample preparation artefacts. Low X-ray absorption contrast in non-mineralised tissue can be enhanced using staining and phase contrast techniques. A step-wise approach, including comparing three stains, was used to develop microCT for bovine tail IVD using laboratory and synchrotron sources. Staining successfully contrasted collagenous structures; however not all regions were stained and the procedure induced macroscopic structural changes. Phase contrast microCT of chemically fixed yet unstained samples resolved the nucleus pulposus, annulus fibrosus and constituent lamellae, and finer structures including collagen bundles and cross-bridges. Using the same imaging methods native tissue scans were of slightly lower contrast but free from sample processing artefacts. In the future these methods may be used to characterise structural remodelling in soft (non-calcified) tissues and to conduct in situ studies of native loaded tissues and constructs to characterise their 3D mechanical properties. PMID- 29176564 TI - Avian Influenza H5N6 Viruses Exhibit Differing Pathogenicities and Transmissibilities in Mammals. AB - Since 2013, highly pathogenic avian influenza H5N6 viruses have emerged in poultry and caused sporadic infections in humans, increasing global concerns regarding their potential as human pandemic threats. Here, we characterized the receptor-binding specificities, pathogenicities and transmissibilities of three H5N6 viruses isolated from poultry in China. The surface genes hemagglutinin (HA) and neuraminidase (NA) were closely related to the human-originating strain A/Changsha/1/2014 (H5N6). Phylogenetic analyses showed that the HA genes were clustered in the 2.3.4.4 clade, and the NA genes were derived from H6N6 viruses. These H5N6 viruses bound both alpha-2,3-linked and alpha-2,6-linked sialic acid receptors, but they exhibited different pathogenicities in mice. In addition, one virus was fully infective and transmissible by direct contact in guinea pigs. These results highlight the importance of monitoring the continual adaptation of H5N6 viruses in poultry due to their potential threat to human health. PMID- 29176565 TI - New Early Cretaceous palaeomagnetic and geochronological results from the far western Lhasa terrane: Contributions to the Lhasa-Qiangtang collision. AB - To better constrain the Lhasa-Qiangtang collision, a combined palaeomagnetic and geochronological study of the far western Lhasa terrane was conducted on the Duoai Formation lava flows (~113-116 Ma), as well as on the Early Cretaceous Jiega Formation limestone. Following detailed rock magnetic, petrographical, and palaeomagnetic experiments, characteristic remanent magnetisation directions were successfully isolated from most samples using principal component analysis. The tilt-corrected direction groups yielded a palaeopole at 69.1 degrees N, 319.8 degrees E with A95 = 4.8 degrees (N = 19). A primary origin for the magnetisation is consistent with positive fold tests. Our results from the Early Cretaceous units, combined with published palaeomagnetic data obtained from Cretaceous strata from the Lhasa and western Qiangtang terranes, show that these two terranes had already collided by the Early Cretaceous, the Lhasa terrane had a relatively east-west alignment, and it remained at a relatively stable palaeolatitude during the entire Cretaceous. Comparing the Cretaceous palaeolatitude calculated for the western Lhasa terrane with those from Eurasia and Mongolia suggests a latitudinal convergence of ~1400 +/- 290 km and ~1800 +/- 300 km, respectively, since the Early Cretaceous. PMID- 29176566 TI - Nanoscale investigation of enhanced electron field emission for silver ion implanted/post-annealed ultrananocrystalline diamond films. AB - Silver (Ag) ions are implanted in ultrananocrystalline diamond (UNCD) films to enhance the electron field emission (EFE) properties, resulting in low turn-on field of 8.5 V/MUm with high EFE current density of 6.2 mA/cm2 (at an applied field of 20.5 V/MUm). Detailed nanoscale investigation by atomic force microscopy based peak force-controlled tunneling atomic force microscopy (PF-TUNA) and ultra high vacuum scanning tunneling microscopy (STM) based current imaging tunneling spectroscopy (CITS) reveal that the UNCD grain boundaries are the preferred electron emission sites. The two scanning probe microscopic results supplement each other well. However, the PF-TUNA measurement is found to be better for explaining the local electron emission behavior than the STM-based CITS technique. The formation of Ag nanoparticles induced abundant sp2 nanographitic phases along the grain boundaries facilitate the easy transport of electrons and is believed to be a prime factor in enhancing the conductivity/EFE properties of UNCD films. The nanoscale understanding on the origin of electron emission sites in Ag-ion implanted/annealed UNCD films using the scanning probe microscopic techniques will certainly help in developing high-brightness electron sources for flat-panel displays applications. PMID- 29176568 TI - Low-temperature fabrication of an HfO2 passivation layer for amorphous indium gallium-zinc oxide thin film transistors using a solution process. AB - We report low-temperature solution processing of hafnium oxide (HfO2) passivation layers for amorphous indium-gallium-zinc oxide (a-IGZO) thin-film transistors (TFTs). At 150 degrees C, the hafnium chloride (HfCl4) precursor readily hydrolyzed in deionized (DI) water and transformed into an HfO2 film. The fabricated HfO2 passivation layer prevented any interaction between the back surface of an a-IGZO TFT and ambient gas. Moreover, diffused Hf4+ in the back channel layer of the a-IGZO TFT reduced the oxygen vacancy, which is the origin of the electrical instability in a-IGZO TFTs. Consequently, the a-IGZO TFT with the HfO2 passivation layer exhibited improved stability, showing a decrease in the threshold voltage shift from 4.83 to 1.68 V under a positive bias stress test conducted over 10,000 s. PMID- 29176567 TI - Plasma cell survival in the absence of B cell memory. AB - Pre-existing serum antibodies play an important role in vaccine-mediated protection against infection but the underlying mechanisms of immune memory are unclear. Clinical studies indicate that antigen-specific antibody responses can be maintained for many years, leading to theories that reactivation/differentiation of memory B cells into plasma cells is required to sustain long-term antibody production. Here, we present a decade-long study in which we demonstrate site-specific survival of bone marrow-derived plasma cells and durable antibody responses to multiple virus and vaccine antigens in rhesus macaques for years after sustained memory B cell depletion. Moreover, BrdU+ cells with plasma cell morphology can be detected for 10 years after vaccination/BrdU administration, indicating that plasma cells may persist for a prolonged period of time in the absence of cell division. On the basis of these results, long lived plasma cells represent a key cell population responsible for long-term antibody production and serological memory. PMID- 29176569 TI - A novel peptidic inhibitor derived from Streptococcus cristatus ArcA attenuates virulence potential of Porphyromonas gingivalis. AB - Periodontitis is a global health problem and the 6th most common infectious disease worldwide. Porphyromonas gingivalis is considered a keystone pathogen in the disease and is capable of elevating the virulence potential of the periodontal microbial community. Strategies that interfere with P. gingivalis colonization and expression of virulence factor are therefore attractive approaches for preventing and treating periodontitis. We have previously reported that an 11-mer peptide (SAPP) derived from Streptococcus cristatus arginine deiminase (ArcA) was able to repress the expression and production of several well-known P. gingivalis virulence factors including fimbrial proteins and gingipains. Herein we expand and develop these studies to ascertain the impact of this peptide on phenotypic properties of P. gingivalis related to virulence potential. We found that growth rate was not altered by exposure of P. gingivalis to SAPP, while monospecies and heterotypic biofilm formation, and invasion of oral epithelial cells were inhibited. Additionally, SAPP was able to impinge the ability of P. gingivalis to dysregulate innate immunity by repressing gingipain associated degradation of interleukin-8 (IL8). Hence, SAPP has characteristics that could be exploited for the manipulation of P. gingivalis levels in oral communities and preventing realization of virulence potential. PMID- 29176572 TI - Emergent wave phenomena in coupled elastic bars: from extreme attenuation to realization of elastodynamic switches. AB - Metamaterials with acoustic and elastic band gaps are of great interest to scientists and engineers. Here, we introduce a novel mechanism for emergence of multiple band gaps with extreme attenuation by coupling continuous one dimensional elastic structures. We show that it is possible to develop extreme attenuation at several frequencies from coupling two homogenous bars of different elastodynamic properties even though each bar individually possesses no such gaps. Moreover, if each bar is a composite on its own, multiple resonant band gaps appear in the compound system which do not exist in either bar. We verify our results by conducting numerical simulations for the elastodynamic response and show that the resonant gaps are efficient in attenuating wave propagation. Furthermore, we show that by carefully tailoring the properties of the coupled bars we may construct elastodynamic signal choppers. These results open a new gate for designing Metamaterial with unique wave modulation properties. PMID- 29176570 TI - Population-scale organization of cerebellar granule neuron signaling during a visuomotor behavior. AB - Granule cells at the input layer of the cerebellum comprise over half the neurons in the human brain and are thought to be critical for learning. However, little is known about granule neuron signaling at the population scale during behavior. We used calcium imaging in awake zebrafish during optokinetic behavior to record transgenically identified granule neurons throughout a cerebellar population. A significant fraction of the population was responsive at any given time. In contrast to core precerebellar populations, granule neuron responses were relatively heterogeneous, with variation in the degree of rectification and the balance of positive versus negative changes in activity. Functional correlations were strongest for nearby cells, with weak spatial gradients in the degree of rectification and the average sign of response. These data open a new window upon cerebellar function and suggest granule layer signals represent elementary building blocks under-represented in core sensorimotor pathways, thereby enabling the construction of novel patterns of activity for learning. PMID- 29176571 TI - Health state dependent multiphoton induced autofluorescence in human 3D in vitro lung cancer model. AB - Lung diseases pose the highest risk of death and lung cancer is a top killer among cancers with a mortality rate up to 70% within 1 year after diagnosis. Such a fast escalation of this cancer development makes early diagnosis and treatment a highly challenging task, and currently there are no effective tools to diagnose the disease at an early stage. The ability to discriminate between healthy and tumorous tissue has made autofluorescence bronchoscopy a promising tool for detection of lung cancer; however, specificity of this method remains insufficiently low. Here, we perform autofluorescence imaging of human lung cancer invading a human functional airway using an in vitro model of Non Small Cell Lung Cancer which combines a reconstituted human airway epithelium, human lung fibroblasts and lung adenocarcinoma cell lines, OncoCilAirTM. By using two photon laser induced autofluorescence microscopy combined with spectrally resolved imaging, we found that OncoCilAirTM provides tissue's health dependent autofluorescence similar as observed in lung tissue in patients. Moreover, we found spectral and intensity heterogeneity of autofluorescence at the edges of tumors. This metabolic related heterogeneity demonstrates ability of tumor to influence its microenvironment. Together, our result shows that OncoCilAirTM is a promising model for lung cancer research. PMID- 29176573 TI - The Retinol Binding Protein Receptor 2 (Rbpr2) is required for Photoreceptor Outer Segment Morphogenesis and Visual Function in Zebrafish. AB - Vitamin A (all-trans retinol) plays critical roles in mammalian development and vision. Since vitamin A is food-derived, tissue-specific uptake and storage mechanism are needed. In the eye, uptake of RBP4-retinol is mediated by the receptor Stra6, whereas the receptor mediating RBP4 binding and retinol transport into the liver has just recently been discovered. Here we examined the role of zebrafish retinol binding protein receptor 2 (Rbpr2) for RBP4-retinol uptake in developing embryos, using eye development and vision as sensitive readouts. In cultured cells, Rbpr2 localized to membranes and promoted RBP4-retinol uptake. In larvae, Rbpr2 expression was detected in developing intestinal enterocytes and liver hepatocytes. Two rbpr2 mutant zebrafish lines, each resulting in Rbpr2 deficiency, exhibit a small eye defect, and systemic malformations including hydrocephaly and cardiac edema, phenotypes associated with vitamin A deficiency. In the retina, Rbpr2 loss resulted in shorter photoreceptor outer segments, mislocalization and decrease in visual pigments, decreased expression of retinoic acid-responsive genes and photoreceptor cell loss, overall leading to a reduction of visual function. Together, these results demonstrate that Rbpr2-mediated RBP4 retinol uptake in developing liver and intestine is necessary to provide sufficient substrate for ocular retinoid production required for photoreceptor cell maintenance and visual function. PMID- 29176574 TI - Habitat foraging niche of a High Arctic zooplanktivorous seabird in a changing environment. AB - Here, we model current and future distribution of a foraging Arctic endemic species, the little auk (Alle alle), a small zooplanktivorous Arctic seabird. We characterized environmental conditions [sea depth, sea surface temperature (SST), marginal sea ice zone (MIZ)] at foraging positions of GPS-tracked individuals from three breeding colonies in Svalbard: one located at the southern rim of the Arctic zone (hereafter 'boreo-Arctic') and two in the high-Arctic zone on Spitsbergen ('high-Arctic'). The birds from one 'high-Arctic' colony, influenced by cold Arctic water, foraged in the shallow shelf zone near the colony. The birds from remaining colonies foraged in a wider range of depths, in a higher SST zone ('boreo-Arctic') or in the productive but distant MIZ (second 'high-Arctic' colony). Given this flexible foraging behaviour, little auks may be temporarily resilient to moderate climate changes. However, our fuzzy logic models of future distribution under scenarios of 1 degrees C and 2 degrees C SST increase predict losses of suitable foraging habitat for the majority of little auk colonies studied. Over longer time scales negative consequences of global warming are inevitable. The actual response of little auks to future environmental conditions will depend on the range of their plasticity and pace of ecosystem changes. PMID- 29176575 TI - Phosphorylation of LAMP2A by p38 MAPK couples ER stress to chaperone-mediated autophagy. AB - Endoplasmic reticulum (ER) and lysosomes coordinate a network of key cellular processes including unfolded protein response (UPR) and autophagy in response to stress. How ER stress is signaled to lysosomes remains elusive. Here we find that ER disturbance activates chaperone-mediated autophagy (CMA). ER stressors lead to a PERK-dependent activation and recruitment of MKK4 to lysosomes, activating p38 MAPK at lysosomes. Lysosomal p38 MAPK directly phosphorylates the CMA receptor LAMP2A at T211 and T213, which causes its membrane accumulation and active conformational change, activating CMA. Loss of ER stress-induced CMA activation sensitizes cells to ER stress-induced death. Neurotoxins associated with Parkinson's disease fully engages ER-p38 MAPK-CMA pathway in the mouse brain and uncoupling it results in a greater loss of SNc dopaminergic neurons. This work identifies the coupling of ER and CMA as a critical regulatory axis fundamental for physiological and pathological stress response. PMID- 29176577 TI - Disulfide loop cleavage of Legionella pneumophila PlaA boosts lysophospholipase A activity. AB - L. pneumophila, an important facultative intracellular bacterium, infects the human lung and environmental protozoa. At least fifteen phospholipases A (PLA) are encoded in its genome. Three of which, namely PlaA, PlaC, and PlaD, belong to the GDSL lipase family abundant in bacteria and higher plants. PlaA is a lysophospholipase A (LPLA) that destabilizes the phagosomal membrane in absence of a protective factor. PlaC shows PLA and glycerophospholipid: cholesterol acyltransferase (GCAT) activities which are activated by zinc metalloproteinase ProA via cleavage of a disulphide loop. In this work, we compared GDSL enzyme activities, their secretion, and activation of PlaA. We found that PlaA majorly contributed to LPLA, PlaC to PLA, and both substrate-dependently to GCAT activity. Western blotting revealed that PlaA and PlaC are type II-secreted and both processed by ProA. Interestingly, ProA steeply increased LPLA but diminished GCAT activity of PlaA. Deletion of 20 amino acids within a predicted disulfide loop of PlaA had the same effect. In summary, we propose a model by which ProA processes PlaA via disulfide loop cleavage leading to a steep increase in LPLA activity. Our results help to further characterize the L. pneumophila GDSL hydrolases, particularly PlaA, an enzyme acting in the Legionella-containing phagosome. PMID- 29176578 TI - A multi-country assessment of factors related to smallholder food security in varying rainfall conditions. AB - Given that smallholder farmers are frequently food insecure and rely significantly on rain-fed agriculture, it is critical to examine climate variability and food insecurity. We utilize data from smallholder farmer surveys from 12 countries with 30 years of rainfall data to examine how rainfall variability and household resources are correlated with food security. We find that on average, households that experienced a drier than average year are 3.81 months food insecure, while households within a normal range of rainfall were 3.67 months food insecure, and wetter than average households were 2.86 months food insecure. Reduced odds of food insecurity is associated with agricultural inputs, ownership of livestock, water use efficiency, financial services, and participation in a group. However, in drier than average households, financial services as compared to agricultural inputs and agroecological practices have a greater prevalence of reduced instances of food insecurity, while agricultural inputs are more common for reduced food insecurity in wetter than average households. Only the use of fertilizer consistently results in reduced odds of food insecurity across all households regardless of rainfall, demonstrating that one-size fits all approaches to food security interventions are likely ineffective, and place-specific interventions considering climatic factors are critically important. PMID- 29176576 TI - The activity of TRAF RING homo- and heterodimers is regulated by zinc finger 1. AB - Ubiquitin chains linked through lysine63 (K63) play a critical role in inflammatory signalling. Following ligand engagement of immune receptors, the RING E3 ligase TRAF6 builds K63-linked chains together with the heterodimeric E2 enzyme Ubc13-Uev1A. Dimerisation of the TRAF6 RING domain is essential for the assembly of K63-linked ubiquitin chains. Here, we show that TRAF6 RING dimers form a catalytic complex where one RING interacts with a Ubc13~Ubiquitin conjugate, while the zinc finger 1 (ZF1) domain and linker-helix of the opposing monomer contact ubiquitin. The RING dimer interface is conserved across TRAFs and we also show that TRAF5-TRAF6 heterodimers form. Importantly, TRAF5 can provide ZF1, enabling ubiquitin transfer from a TRAF6-bound Ubc13 conjugate. Our study explains the dependence of activity on TRAF RING dimers, and suggests that both homo- and heterodimers mediated by TRAF RING domains have the capacity to synthesise ubiquitin chains. PMID- 29176579 TI - Regulation of mating type switching by the mating type genes and RME1 in Ogataea polymorpha. AB - Saccharomyces cerevisiae and its closely related yeasts undergo mating type switching by replacing DNA sequences at the active mating type locus (MAT) with one of two silent mating type cassettes. Recently, a novel mode of mating type switching was reported in methylotrophic yeast, including Ogataea polymorpha, which utilizes chromosomal recombination between inverted-repeat sequences flanking two MAT loci. The inversion is highly regulated and occurs only when two requirements are met: haploidy and nutritional starvation. However, links between this information and the mechanism associated with mating type switching are not understood. Here we investigated the roles of transcription factors involved in yeast sexual development, such as mating type genes and the conserved zinc finger protein Rme1. We found that co-presence of mating type a1 and alpha2 genes was sufficient to prevent mating type switching, suggesting that ploidy information resides solely in the mating type locus. Additionally, RME1 deletion resulted in a reduced rate of switching, and ectopic expression of O. polymorpha RME1 overrode the requirement for starvation to induce MAT inversion. These results suggested that mating type switching in O. polymorpha is likely regulated by two distinct transcriptional programs that are linked to the ploidy and transmission of the starvation signal. PMID- 29176580 TI - Reduced loss aversion in pathological gambling and alcohol dependence is associated with differential alterations in amygdala and prefrontal functioning. AB - Diagnostic criteria for pathological gambling and alcohol dependence (AD) include repeated addictive behavior despite severe negative consequences. However, the concept of loss aversion (LA) as a facet of value-based decision making has not yet been used to directly compare these disorders. We hypothesized reduced LA in pathological gamblers (PG) and AD patients, correlation of LA with disorder severity, and reduced loss-related modulation of brain activity. 19 PG subjects, 15 AD patients and 17 healthy controls (HC) engaged in a LA task in a functional magnetic resonance imaging setting. Imaging analyses focused on neural gain and loss sensitivity in the meso-cortico-limbic network of the brain. Both PG and AD subjects showed reduced LA. AD subjects showed altered loss-related modulation of activity in lateral prefrontal regions. PG subjects showed indication of altered amygdala-prefrontal functional connectivity. Although we observed reduced LA in both a behavioral addiction and a substance-related disorder our neural findings might challenge the notion of complete neuro-behavioral congruence of substance use disorders and behavioral addictions. PMID- 29176581 TI - Functional horizontal gene transfer from bacteria to eukaryotes. AB - Bacteria influence eukaryotic biology as parasitic, commensal or beneficial symbionts. Aside from these organismal interactions, bacteria have also been important sources of new genetic sequences through horizontal gene transfer (HGT) for eukaryotes. In this Review, we focus on gene transfers from bacteria to eukaryotes, discuss how horizontally transferred genes become functional and explore what functions are endowed upon a broad diversity of eukaryotes by genes derived from bacteria. We classify HGT events into two broad types: those that maintain pre-existing functions and those that provide the recipient with new functionality, including altered host nutrition, protection and adaptation to extreme environments.

PMID- 29176582 TI - Listeria monocytogenes: towards a complete picture of its physiology and pathogenesis. AB - Listeria monocytogenes is a food-borne pathogen responsible for a disease called listeriosis, which is potentially lethal in immunocompromised individuals. This bacterium, first used as a model to study cell-mediated immunity, has emerged over the past 20 years as a paradigm in infection biology, cell biology and fundamental microbiology. In this Review, we highlight recent advances in the understanding of human listeriosis and L. monocytogenes biology. We describe unsuspected modes of hijacking host cell biology, ranging from changes in organelle morphology to direct effects on host transcription via a new class of bacterial effectors called nucleomodulins. We then discuss advances in understanding infection in vivo, including the discovery of tissue-specific virulence factors and the 'arms race' among bacteria competing for a niche in the microbiota. Finally, we describe the complexity of bacterial regulation and physiology, incorporating new insights into the mechanisms of action of a series of riboregulators that are critical for efficient metabolic regulation, antibiotic resistance and interspecies competition.

PMID- 29176587 TI - Insect-based diet, a promising nutritional source, modulates gut microbiota composition and SCFAs production in laying hens. AB - Insects could be potential nutritional sources both for humans and animals. Among these, Hermetia illucens, with good amount of chitin and proteins, represents a suitable diet replacement for laying hens. Little is known about insect diet effects on the microbial ecology of the gastrointestinal tract and bacterial metabolites production. In this study we investigated the effect of H. illucens larvae meal administration on cecal microbiota and short chain fatty acids (SCFAs) production in laying hens. 16S rDNA sequencing showed strong differences between cecal microbiota of soybean (SD) and insect diet (ID) groups both in type and relative abundance (unweighted and weighted beta diversity) of microbial species. In particular, Bacteroides plebeius, Elusimicrobium minutum, Alkaliphilus transvaalensis, Christensenella minuta, Vallitalea guaymasensis and Flavonifractor plautii represented the principal contributors of changes in gut microbiota composition of ID group (FDR p-values < 0.05). Of these, F. plautii, C. minuta and A. transvaalensis have the potential to degrade the chitin's insect meal and correlated with the observed high levels of gut SCFAs produced in ID group. These microorganisms may thus connect the chitin degradation with high SCFAs production. Our results suggest H. illucens as a potential prebiotic by well feeding gut microbiota. PMID- 29176588 TI - Alanine substitution in cellobiohydrolase provides new insights into substrate threading. AB - The glycoside hydrolase family 7 (GH7) member cellobiohydrolase (CBH) is a key enzyme that degrades crystalline cellulose, an important structural component of plant cell walls. As GH7 CBH is a major component in the enzyme mixture used to degrade biomass into fermentable glucose in biorefineries, enhancing its catalytic activity will significantly impact development in this field. GH7 CBH possesses a catalytic tunnel through which cellulose substrates are threaded and hydrolysed. Despite numerous studies dissecting this processive mechanism, the role of amino acid residues in the tunnel remains not fully understood. Herein, we examined the respective contributions of nine amino acid residues in the catalytic tunnel of GH7 CBH from Talaromyces cellulolyticus by substitution with alanine. As a result, N62A and K203A mutants were found to possess significantly higher cellulase activities than wild type. Molecular dynamics simulations showed that the N62 residue interacted strongly with the cellulose substrate, impeding threading, while the N62A mutant allowed cellulose to proceed more smoothly. Furthermore, the W63 residue was observed to facilitate twisting of the cellulose substrate in our simulations. This study helps elucidate cellulose threading and provides insight into biomass hydrolysis. PMID- 29176589 TI - Australia's influenza pandemic preparedness plans: an analysis. AB - We analysed Australian plans issued by the public sector and current at the time of the last human pandemic in 2009. They came from various levels of governance, and offered guidance in key domains. Using 13 established criteria, we rated 10 plans (national, state, and territorial) for their usefulness to guide health and medical intervention, business continuity, and crisis communication, plus consideration of at-risk populations. The intended end-user of most plans was not clear, whether hospital manager, health worker, or policy maker. Scores ranged from 8 to 29 of a maximum possible of 39, with many inconsistencies between plans. Health system-related issues were better addressed than critical infrastructure and essential systems resilience. The needs of Indigenous populations and use of pneumococcal vaccination and antibiotics were rarely considered in plans. Pandemic response would be more effective if plans were standardised, clear, and were to include overlooked dimensions of a pandemic's impact as well as guidance for specified end-users. PMID- 29176590 TI - Nanocarrier-mediated delivery of alpha-mangostin for non-surgical castration of male animals. AB - The overpopulation of abandoned and stray companion animals has become a global crisis. The main purpose of this study was to develop a novel nanomedicine-based antifertility compound for non-surgical castration of male animals. Mangosteen (Garcinia mangostana L) pericarp extract has been shown to exhibit anti-fertility property. alpha-mangostin (AM)-loaded nanostructured lipid carrier (AM-NLC) was developed to improve male germ cell apoptosis. This study was conducted to investigate physicochemical properties of AM-NLC and determine the biological effects of AM-NLC on spermatogonia cells and testicular explants obtained from castrated testes. AM-NLC was produced through a hot homogenization technique. The negatively charged particle of AM-NLC was nano-sized with a narrow dispersity. AM NLC exhibited antiproliferative activity towards spermatogonium cells. It induced apoptosis in the cells. In addition, AM-NLC exhibited anti-inflammatory activities in lipopolysaccharide-activated macrophages. Abnormal anatomy of seminiferous tubule was noted following treatment of testicular explant with AM NLC. This nanomedicine-based sterilant would be a promising platform that may have utility in non-surgical castration of male animals by intra-testicular injection.

AB - Novel metabolites distinct from canonical pathways can be identified through the integration of three cheminformatics tools: BinVestigate, which queries the BinBase gas chromatography-mass spectrometry (GC-MS) metabolome database to match unknowns with biological metadata across over 110,000 samples; MS-DIAL 2.0, a software tool for chromatographic deconvolution of high-resolution GC-MS or liquid chromatography-mass spectrometry (LC-MS); and MS-FINDER 2.0, a structure elucidation program that uses a combination of 14 metabolome databases in addition to an enzyme promiscuity library. We showcase our workflow by annotating N-methyl-uridine monophosphate (UMP), lysomonogalactosyl-monopalmitin, N methylalanine, and two propofol derivatives. PMID- 29176592 TI - A permanent window for the murine lung enables high-resolution imaging of cancer metastasis. AB - Stable, high-resolution intravital imaging of the lung has become possible through the utilization of vacuum-stabilized imaging windows. However, this technique is extremely invasive and limited to only hours in duration. Here we describe a minimally invasive, permanently implantable window for high-resolution intravital imaging of the murine lung that allows the mouse to survive surgery, recover from anesthesia, and breathe independently. Compared to vacuum-stabilized windows, this window produces the same high-quality images without vacuum-induced artifacts; it is also less invasive, which allows imaging of the same lung tissue over a period of weeks. We further adapt the technique of microcartography for reliable relocalization of the same cells longitudinally. Using commonly employed experimental, as well as more clinically relevant, spontaneous metastasis models, we visualize all stages of metastatic seeding, including: tumor cell arrival; extravasation; growth and progression to micrometastases; as well as tumor microenvironment of metastasis function, the hallmark of hematogenous dissemination of tumor cells. PMID- 29176593 TI - Shared genetic etiology of hypertension and stroke: evidence from bioinformatics analysis of genome-wide association studies. AB - Hypertension is the most significant modifiable risk factor for cerebrovascular disease. It has been estimated that about 54% of strokes worldwide can be attributed to hypertension. However, there has not been a systematic study assessing the shared genetic susceptibility to hypertension and stroke on a genome-wide level. In this study, SNPs associated with essential hypertension and stroke were collected from the NHGRI-EBI GWAS catalog, and genotype imputation were conducted using information from the 1000 Genomes Project. Subsequently, the SNPs and the mapped genes were compared between the two diseases. Finally, functional clustering was performed, and the enriched GO terms and KEGG pathways were further compared between hypertension and stroke. Comparison of these two groups of SNPs and genes identified only one shared SNP (rs3184504) and 11 shared genes. After genotype imputation, 129 shared SNPs and 16 shared genes were identified. These genes were significantly enriched in 10 GO terms, which were mainly involved in lipoprotein and triglyceride metabolism. Additionally, KEGG analysis identified one pathway, glycerolipid metabolism, as being significantly enriched in both diseases. The present study strongly suggests that the gene network regulating lipid metabolism and blood circulation is the major shared genetic etiology of hypertension and stroke. PMID- 29176594 TI - Subtype prediction of primary aldosteronism by combining aldosterone concentrations in the left adrenal vein and inferior vena cava: a multicenter collaborative study on adrenal venous sampling. AB - Subtype diagnosis of primary aldosteronism (PA) by adrenal vein sampling (AVS) is recommended as a mandatory step for indicating adrenal surgery. It is a technically demanding procedure, especially in the right adrenal vein. The aim of the study was to predict the subtype diagnosis in the absence of values from the right AVS. From the databases of nine centers (WAVES-J), 308 patients with PA who underwent successful AVS were studied. Based on the ipsilateral ratio (IR) (aldosterone/cortisol ratio of the left adrenal vein [A/Cleft AV] / aldosterone/cortisol ratio of the inferior vena cava [A/CIVC]), the patients were divided into two groups: the patients with IR >= 1.0 (n = 262) and those with IR < 1.0 (n = 46). In patients with IR > 1.0, the A/Cleft AV was significantly higher in patients with the left unilateral subtype than in patients with the bilateral subtype. Receiver operating characteristic (ROC) curve analysis revealed that an A/Cleft AV cutoff >68 showed 70.8% sensitivity and 93.5% specificity for the left unilateral subtype. On the other hand, in patients with IR < 1.0, the A/Cleft AV was significantly lower in patients with the right unilateral subtype. ROC analysis revealed that an A/Cleft AV cutoff <9 showed 86.7% sensitivity and 75.0% specificity for the right unilateral subtype. Hence, the combination of the IR and A/C ratio in the left adrenal vein is useful for predicting the subtype. The present results provide important information for patients with PA in whom AVS was unsuccessful in the right adrenal vein. PMID- 29176595 TI - The presence of nonfunctioning adrenal incidentalomas increases arterial hypertension frequency and severity, and is associated with cortisol levels after dexamethasone suppression test. AB - There are limited data regarding the frequency of hypertension in nonfunctioning adrenal incidentaloma (NFAI). Our objectives were to investigate rates of hypertension and resistant hypertension in NFAI patients, and compare them to a control group without adrenal adenoma. We also aimed to evaluate the relationship between cortisol levels after 1 mg-dexamethasone suppression test (DST) and hypertension in NFAI patients. We selected 40 patients with NFAI and 40 control patients over the age of 18 without adrenal lesions on abdominal imaging. Data regarding hypertension, resistant hypertension, number, and type of antihypertensive drugs were collected from each subject. Blood samples for C reactive protein (CRP), plasma adrenocorticotropic hormone (ACTH) and dehydroepiandrosterone sulfate (DHEA-S) were also collected from the patients. Age, gender, race, smoking status, menopause status and BMI were comparable between patient and control groups. Patients with NFAI had a higher frequency of hypertension (72.5 vs. 47.5%; p = 0.04), resistant hypertension (37.9 vs. 11.1%; p = 0.04) and took three or more antihypertensive drugs (33.3 vs. 5.2%; p = 0.002) when compared to the controls, respectively. NFAI patients with hypertension had higher mean cortisol levels after 1 mg-DST when compared to NFAI patients without hypertension (1.3 +/- 0.3 vs. 1.0 +/- 0.4; p = 0.03, respectively). We found a negative correlation between cortisol levels after 1 mg DST DHEA-S levels (r = -0.61; p < 0.001) and a positive correlation with CRP levels (r = 0.44; p = 0.02). In conclusion, NFAI patients presented a higher frequency of hypertension, resistant hypertension and used more antihypertensive medications when compared to the control group. We found an association between hypertension in NFAI patients and cortisol levels after 1 mg-DST. PMID- 29176597 TI - In vivo evidence that RBM5 is a tumour suppressor in the lung. AB - Cigarette smoking is undoubtedly a risk factor for lung cancer. Moreover, smokers with genetic mutations on chromosome 3p21.3, a region frequently deleted in cancer and notably in lung cancer, have a dramatically higher risk of aggressive lung cancer. The RNA binding motif 5 (RBM5) is one of the component genes in the 3p21.3 tumour suppressor region. Studies using human cancer specimens and cell lines suggest a role for RBM5 as a tumour suppressor. Here we demonstrate, for the first time, an in vivo role for RBM5 as a tumour suppressor in the mouse lung. We generated Rbm5 loss-of-function mice and exposed them to a tobacco carcinogen NNK. Upon exposure to NNK, Rbm5 loss-of-function mice developed lung cancer at similar rates to wild type mice. As tumourigenesis progressed, however, reduced Rbm5 expression lead to significantly more aggressive lung cancer i.e. increased adenocarcinoma nodule numbers and tumour size. Our data provide in vivo evidence that reduced RBM5 function, as occurs in a large number of patients, coupled with exposure to tobacco carcinogens is a risk factor for an aggressive lung cancer phenotype. These data suggest that RBM5 loss-of-function likely underpins at least part of the pro-tumourigenic consequences of 3p21.3 deletion in humans. PMID- 29176598 TI - Population pharmacokinetics of remifentanil in critically ill patients receiving extracorporeal membrane oxygenation. AB - Extracorporeal membrane oxygenation (ECMO) is associated with pharmacokinetic (PK) changes of drugs. It presents considerable challenges to providing optimal dosing regimens for patients receiving ECMO. We aimed to describe the population PK of remifentanil in critically ill adult patients receiving venoartrial extracorporeal membrane oxygenation (VA-ECMO) and to identify determinants associated with altered remifentanil concentrations. The population PK model of remifentanil was developed using nonlinear mixed effects modelling (NONMEM). Fifteen adult patients who received a continuous infusion of remifentanil during VA-ECMO participated in the study. The PK of remifentanil was best described by a one-compartment model with additive and proportional residual errors. Remifentanil concentrations were affected by sex and ECMO pump speed. The final PK model included the effect of sex and ECMO pump speed on clearance is developed as followed: clearance (L/h) = 366 * 0.502sex * (ECMO pump speed/2350)2.04 and volume (L) = 41. Remifentanil volume and clearance were increased in adult patients on VA-ECMO compared with previously reported patients not on ECMO. We suggest that clinicians should consider an increased remifentanil dosing to achieve the desired level of sedation and provide a dosing regimen according to sex and ECMO pump speed. PMID- 29176596 TI - Quenching protein dynamics interferes with HIV capsid maturation. AB - Maturation of HIV-1 particles encompasses a complex morphological transformation of Gag via an orchestrated series of proteolytic cleavage events. A longstanding question concerns the structure of the C-terminal region of CA and the peptide SP1 (CA-SP1), which represents an intermediate during maturation of the HIV-1 virus. By integrating NMR, cryo-EM, and molecular dynamics simulations, we show that in CA-SP1 tubes assembled in vitro, which represent the features of an intermediate assembly state during maturation, the SP1 peptide exists in a dynamic helix-coil equilibrium, and that the addition of the maturation inhibitors Bevirimat and DFH-055 causes stabilization of a helical form of SP1. Moreover, the maturation-arresting SP1 mutation T8I also induces helical structure in SP1 and further global dynamical and conformational changes in CA. Overall, our results show that dynamics of CA and SP1 are critical for orderly HIV-1 maturation and that small molecules can inhibit maturation by perturbing molecular motions. PMID- 29176599 TI - Benchmarking organic mixed conductors for transistors. AB - Organic mixed conductors have garnered significant attention in applications from bioelectronics to energy storage/generation. Their implementation in organic transistors has led to enhanced biosensing, neuromorphic function, and specialized circuits. While a narrow class of conducting polymers continues to excel in these new applications, materials design efforts have accelerated as researchers target new functionality, processability, and improved performance/stability. Materials for organic electrochemical transistors (OECTs) require both efficient electronic transport and facile ion injection in order to sustain high capacity. In this work, we show that the product of the electronic mobility and volumetric charge storage capacity (uC*) is the materials/system figure of merit; we use this framework to benchmark and compare the steady-state OECT performance of ten previously reported materials. This product can be independently verified and decoupled to guide materials design and processing. OECTs can therefore be used as a tool for understanding and designing new organic mixed conductors. PMID- 29176600 TI - Cleavage of poly(A)-binding protein by duck hepatitis A virus 3C protease. AB - During viral infections, some viruses subvert the host proteins to promote the translation or RNA replication with their protease-mediated cleavage. Poly (A) binding protein (PABP) is a target for several RNA viruses; however, the impact of duck hepatitis A virus (DHAV) on PABP remains unknown. In this study, we demonstrated for the first time that DHAV infection stimulates a decrease in endogenous PABP and generates two cleavage fragments. On the basis of in vitro cleavage assays, an accumulation of PABP cleavage fragments was detected in duck embryo fibroblast (DEF) cell extracts incubated with functional DHAV 3C protease. In addition, DHAV 3C protease was sufficient for the cleavage of recombinant PABP without the assistance of other eukaryotic cellular cofactors. Furthermore, using site-directed mutagenesis, our data demonstrated a 3C protease cleavage site located between Q367 and G368 in duck PABP. Moreover, the knockdown of PABP inhibited the production of viral RNA, and the C-terminal domain of PABP caused a reduction in viral replication compared to the N-terminal domain. Taken together, these findings suggested that DHAV 3C protease mediates the cleavage of PABP, which may be a strategy to manipulate viral replication. PMID- 29176601 TI - Emergence of tick-borne diseases at northern latitudes in Europe: a comparative approach. AB - The factors that drive the emergence of vector-borne diseases are difficult to identify due to the complexity of the pathogen-vector-host triad. We used a novel comparative approach to analyse four long-term datasets (1995-2015) on the incidence of tick-borne diseases in humans and livestock (Lyme disease, anaplasmosis and babesiosis) over a geographic area that covered the whole of Norway. This approach allowed us to separate general (shared vector) and specific (pathogen reservoir host) limiting factors of tick-borne diseases, as well as the role of exposure (shared and non-shared pathogens in different hosts). We found broadly similar patterns of emergence across the four tick-borne diseases. Following initial increases during the first decade of the time series, the numbers of cases peaked at slightly different years and then stabilized or declined in the most recent years. Contrasting spatial patterns of disease incidence were consistent with exposure to ticks being an important factor influencing disease incidence in livestock. Uncertainty regarding the reservoir host(s) of the pathogens causing anaplasmosis and babesiosis prevented a firm conclusion regarding the role of the reservoir host-pathogen distribution. Our study shows that the emergence of tick-borne diseases at northern latitudes is linked to the shared tick vector and that variation in host-pathogen distribution and exposure causes considerable variation in emergence. PMID- 29176602 TI - Identification of DmTTLL5 as a Major Tubulin Glutamylase in the Drosophila Nervous System. AB - Microtubules (MTs) play crucial roles during neuronal life. They are formed by heterodimers of alpha and beta-tubulins, which are subjected to several post translational modifications (PTMs). Amongst them, glutamylation consists in the reversible addition of a variable number of glutamate residues to the C-terminal tails of tubulins. Glutamylation is the most abundant MT PTM in the mammalian adult brain, suggesting that it plays an important role in the nervous system (NS). Here, we show that the previously uncharacterized CG31108 gene encodes an alpha-tubulin glutamylase acting in the Drosophila NS. We show that this glutamylase, which we named DmTTLL5, initiates MT glutamylation specifically on alpha-tubulin, which are the only glutamylated tubulin in the Drosophila brain. In DmTTLL5 mutants, MT glutamylation was not detected in the NS, allowing for determining its potential function. DmTTLL5 mutants are viable and we did not find any defect in vesicular axonal transport, synapse morphology and larval locomotion. Moreover, DmTTLL5 mutant flies display normal negative geotaxis behavior and their lifespan is not altered. Thus, our work identifies DmTTLL5 as the major enzyme responsible for initiating neuronal MT glutamylation specifically on alpha-tubulin and we show that the absence of MT glutamylation is not detrimental for Drosophila NS function. PMID- 29176603 TI - The association between visual function and retinal structure in chronic central serous chorioretinopathy. AB - The purpose of the current study was to investigate the association between visual function and retinal structure in central serous chorioretinopathy (CSC). In 22 eyes of 22 chronic CSC patients with serous retinal detachment at the macula, retinal sensitivity was measured using MP3 microperimetry (NIDEK, Japan) and mean sensitivity within two degrees (MS2), four degrees (MS4) and six degrees (MS6), as well as foveal sensitivity (MS0), were calculated. Retinal structure was measured using optical coherence tomography (OCT, Spectralis, Heidelberg). The relationship between visual function (LogMAR best-corrected visual acuity [LogMAR VA] and MS0, MS2, MS4, MS6) and serous retinal detachment height at the fovea (SRDH), central retinal thickness (CRT), macular volume (MV) and central choroidal thickness (CCT) was investigated. There were significant negative correlations between LogMAR VA and MS0 (p = 0.016), MS2 (p = 0.049). No significant relationship was observed between LogMAR VA and SRDH (p = 0.97) although there was a significant negative correlation between SRDH and MS2 (p = 0.028), MS4 (p = 0.049), MS6 (p = 0.023). In conclusion, in CSC, serous retinal detachment was significantly correlated with retinal sensitivity measured with MP3, but not with LogMAR VA. PMID- 29176604 TI - A comparison of micro-CT and histomorphometry for evaluation of osseointegration of PEO-coated titanium implants in a rat model. AB - The aim of the present study was to determine the correlation between bone volume density (BV/TV) around a titanium implant determined by micro-computed tomography (micro-CT) and bone area density (BA/TA) measurements obtained using histomorphometry. An intramedullary rat femur implant model was evaluated to compare raw titanium implants with plasma electrolytic oxidation (PEO)-coated titanium implants. Titanium and PEO-treated titanium pins were inserted into rat femurs under general anesthesia. The animals were sacrificed and femurs harvested at 0, 2, 4 and 6 weeks, and subsequently, histomorphometry and micro-CT were performed. BV/TV and BA/TA values were strongly and positively correlated at all time points and locations (with all correlation coefficients being >0.8 and with P < 0.001). BV/TV and BA/TA were significantly higher proximal to the growth plate than distal to the growth plate, with estimated differences of 14.10% (P < 0.001) and 11.95% (P < 0.001), respectively. BV/TV and BA/TA were significantly higher on the PEO-coated surface than on the raw titanium surface, with estimated differences of 3.20% (P = 0.044) and 4.10% (P = 0.018), respectively. Therefore, quantitative micro-CT analysis of BV/TV is correlated with BA/TA determined by histomorphometry when artifacts around titanium implants are minimized by a region of interest modification. PMID- 29176605 TI - Mechanistic insight to ROS and Apoptosis regulated cytotoxicity inferred by Green synthesized CuO nanoparticles from Calotropis gigantea to Embryonic Zebrafish. AB - With the rapid development of nanotechnology, much has been anticipated with copper oxide nanoparticles (CuO NP) due to their extensive industrial and commercial application. However, it has raised concern over the environmental safety and human health effects. In this study, CuO nanoparticles were synthesized using the green method with floral extract of Calotropis gigantea and characterized by standard physiochemical techniques like DLS, Zeta potential determination, UV- Visible Spectroscopy, XRD, FTIR, FESEM, and TEM. Mechanistic cytotoxicity studies were performed using experimental and computational assays including morphological analysis, hatching, and viability rate analysis along with ROS and apoptosis analysis. Physiochemical characterization of CuO NP determined the size and zeta potential of synthesized nanoparticles to be 30 +/- 09 nm to 40 +/- 2 nm and -38 mV +/- 12 mV respectively. Cytotoxicity evaluation with Zebrafish revealed malfunctioned organ development with differential viability and hatching rate at 48 hpf and 72 hpf with LC50 of 175 +/- 10 mg/l. Computational analysis depicted the influential role of CuO nanoparticles on zebrafish embryo's he1a, sod1 and p53 functional expression through hydrophobic and hydrogen bond interaction with amino acid residues. Study demonstrated valuable information of cytotoxic impact which can be influential in further studies of their eco-toxicological effects.

AB - A large spin-dependent and electric field-tunable magnetoresistance of a two dimensional electron system is a key ingredient for the realization of many novel concepts for spin-based electronic devices. The low magnetoresistance observed during the last few decades in devices with lateral semiconducting transport channels between ferromagnetic source and drain contacts has been the main obstacle for realizing spin field effect transistor proposals. Here, we show both a large two-terminal magnetoresistance in a lateral spin valve device with a two dimensional channel, with up to 80% resistance change, and tunability of the magnetoresistance by an electric gate. The enhanced magnetoresistance is due to finite electric field effects at the contact interface, which boost spin-to charge conversion. The gating scheme that we use is based on switching between uni- and bidirectional spin diffusion, without resorting to spin-orbit coupling. Therefore, it can also be employed in materials with low spin-orbit coupling. PMID- 29176608 TI - Computational derivation of a molecular framework for hair follicle biology from disease genes. AB - Knowledge about genetic drivers of disease increases the efficiency of interpreting patient DNA sequence and helps to identify and prioritize biological points of intervention. Discoveries of genes with single mutations exerting substantial phenotypic impact reliably provide new biological insight, although such approaches tend to generate knowledge that is disjointed from the complexity of biological systems governed by elaborate networks. Here we sought to facilitate diagnostic sequencing for hair disorders and assess the underlying biology by compiling an archive of 684 genes discovered in studies of monogenic disorders and identifying molecular annotations enriched by them. To demonstrate utility for this dataset, we performed two data driven analyses. First, we extracted and analyzed data implicating enriched signaling pathways and identified previously unrecognized contributions from Hippo signaling. Second, we performed hierarchical clustering on the entire dataset to investigate the underlying causal structure of hair disorders. We identified 35 gene clusters representing genetically derived biological modules that provide a foundation for the development of a new disease taxonomy grounded in biology, rather than clinical presentations alone. This Resource will be useful for diagnostic sequencing in patients with diseases affecting the hair follicle, improved characterization of hair follicle biology, and methods development in precision medicine. PMID- 29176609 TI - Very high density EEG elucidates spatiotemporal aspects of early visual processing. AB - Standard human EEG systems based on spatial Nyquist estimates suggest that 20-30 mm electrode spacing suffices to capture neural signals on the scalp, but recent studies posit that increasing sensor density can provide higher resolution neural information. Here, we compared "super-Nyquist" density EEG ("SND") with Nyquist density ("ND") arrays for assessing the spatiotemporal aspects of early visual processing. EEG was measured from 128 electrodes arranged over occipitotemporal brain regions (14 mm spacing) while participants viewed flickering checkerboard stimuli. Analyses compared SND with ND-equivalent subsets of the same electrodes. Frequency-tagged stimuli were classified more accurately with SND than ND arrays in both the time and the frequency domains. Representational similarity analysis revealed that a computational model of V1 correlated more highly with the SND than the ND array. Overall, SND EEG captured more neural information from visual cortex, arguing for increased development of this approach in basic and translational neuroscience. PMID- 29176611 TI - Dependence of the sliding distance of a one-dimensional atom chain on initial velocity. AB - In our daily lives, a body with a high initial velocity sliding freely on a rough surface moves a longer distance than that with a low initial velocity. However, such a phenomenon may not occur in the microscopic world. The dynamical behavior of a one-dimensional atom chain (1DAC) sliding on a substrate is investigated in this study by using a modified Frenkel-Kontorova model, in which the vibration of atoms on the substrate is considered. The dependence of sliding distance on initial velocity is examined. Result shows that although sliding distance is proportional to the initial value for most velocities, such a linear relation does not exist in some special velocities. This phenomenon is explained by a theoretical analysis of phonon excitation. The physical process is divided into three stages. The first stage is a superlubric sliding process with small amplitude of the vibrication of the atoms. The single-mode phonon is excited in the second stage. In the third stage, the system exhibits instability because of multiple-mode phonon excitations. In addition, the dependence of the coupling strength between 1DAC and the substrate is investigated. The findings are helpful in understanding the energy dissipation mechanism of friction. PMID- 29176610 TI - Reconstitution of the complete pathway of ITS2 processing at the pre-ribosome. AB - Removal of internal transcribed spacer 2 (ITS2) from pre-ribosomal RNA is essential to make functional ribosomes. This complicated processing reaction begins with a single endonucleolytic cleavage followed by exonucleolytic trimming at both new cleavage sites to generate mature 5.8S and 25S rRNA. We reconstituted the 7S->5.8S processing branch within ITS2 using purified exosome and its nuclear cofactors. We find that both Rrp44's ribonuclease activities are required for initial RNA shortening followed by hand over to the exonuclease Rrp6. During the in vitro reaction, ITS2-associated factors dissociate and the underlying 'foot' structure of the pre-60S particle is dismantled. 7S pre-rRNA processing is independent of 5S RNP rotation, but 26S->25S trimming is a precondition for subsequent 7S->5.8S processing. To complete the in vitro assay, we reconstituted the entire cycle of ITS2 removal with a total of 18 purified factors, catalysed by the integrated activities of the two participating RNA-processing machines, the Las1 complex and nuclear exosome. PMID- 29176612 TI - Biased and unbiased perceptual decision-making on vocal emotions. AB - Perceptual decision-making on emotions involves gathering sensory information about the affective state of another person and forming a decision on the likelihood of a particular state. These perceptual decisions can be of varying complexity as determined by different contexts. We used functional magnetic resonance imaging and a region of interest approach to investigate the brain activation and functional connectivity behind two forms of perceptual decision making. More complex unbiased decisions on affective voices recruited an extended bilateral network consisting of the posterior inferior frontal cortex, the orbitofrontal cortex, the amygdala, and voice-sensitive areas in the auditory cortex. Less complex biased decisions on affective voices distinctly recruited the right mid inferior frontal cortex, pointing to a functional distinction in this region following decisional requirements. Furthermore, task-induced neural connectivity revealed stronger connections between these frontal, auditory, and limbic regions during unbiased relative to biased decision-making on affective voices. Together, the data shows that different types of perceptual decision making on auditory emotions have distinct patterns of activations and functional coupling that follow the decisional strategies and cognitive mechanisms involved during these perceptual decisions. PMID- 29176613 TI - Global landscape of cell envelope protein complexes in Escherichia coli. AB - Bacterial cell envelope protein (CEP) complexes mediate a range of processes, including membrane assembly, antibiotic resistance and metabolic coordination. However, only limited characterization of relevant macromolecules has been reported to date. Here we present a proteomic survey of 1,347 CEPs encompassing 90% inner- and outer-membrane and periplasmic proteins of Escherichia coli. After extraction with non-denaturing detergents, we affinity-purified 785 endogenously tagged CEPs and identified stably associated polypeptides by precision mass spectrometry. The resulting high-quality physical interaction network, comprising 77% of targeted CEPs, revealed many previously uncharacterized heteromeric complexes. We found that the secretion of autotransporters requires translocation and the assembly module TamB to nucleate proper folding from periplasm to cell surface through a cooperative mechanism involving the beta-barrel assembly machinery. We also establish that an ABC transporter of unknown function, YadH, together with the Mla system preserves outer membrane lipid asymmetry. This E. coli CEP 'interactome' provides insights into the functional landscape governing CE systems essential to bacterial growth, metabolism and drug resistance. PMID- 29176614 TI - Inhibition of 53BP1 favors homology-dependent DNA repair and increases CRISPR Cas9 genome-editing efficiency. AB - Programmable nucleases, such as Cas9, are used for precise genome editing by homology-dependent repair (HDR). However, HDR efficiency is constrained by competition from other double-strand break (DSB) repair pathways, including non homologous end-joining (NHEJ). We report the discovery of a genetically encoded inhibitor of 53BP1 that increases the efficiency of HDR-dependent genome editing in human and mouse cells. 53BP1 is a key regulator of DSB repair pathway choice in eukaryotic cells and functions to favor NHEJ over HDR by suppressing end resection, which is the rate-limiting step in the initiation of HDR. We screened an existing combinatorial library of engineered ubiquitin variants for inhibitors of 53BP1. Expression of one variant, named i53 (inhibitor of 53BP1), in human and mouse cells, blocked accumulation of 53BP1 at sites of DNA damage and improved gene targeting and chromosomal gene conversion with either double-stranded DNA or single-stranded oligonucleotide donors by up to 5.6-fold. Inhibition of 53BP1 is a robust method to increase efficiency of HDR-based precise genome editing. PMID- 29176615 TI - Design and applications of a clamp for Green Fluorescent Protein with picomolar affinity. AB - Green fluorescent protein (GFP) fusions are pervasively used to study structures and processes. Specific GFP-binders are thus of great utility for detection, immobilization or manipulation of GFP-fused molecules. We determined structures of two designed ankyrin repeat proteins (DARPins), complexed with GFP, which revealed different but overlapping epitopes. Here we show a structure-guided design strategy that, by truncation and computational reengineering, led to a stable construct where both can bind simultaneously: by linkage of the two binders, fusion constructs were obtained that "wrap around" GFP, have very high affinities of about 10-30 pM, and extremely slow off-rates. They can be natively produced in E. coli in very large amounts, and show excellent biophysical properties. Their very high stability and affinity, facile site-directed functionalization at introduced unique lysines or cysteines facilitate many applications. As examples, we present them as tight yet reversible immobilization reagents for surface plasmon resonance, as fluorescently labelled monomeric detection reagents in flow cytometry, as pull-down ligands to selectively enrich GFP fusion proteins from cell extracts, and as affinity column ligands for inexpensive large-scale protein purification. We have thus described a general design strategy to create a "clamp" from two different high-affinity repeat proteins, even if their epitopes overlap. PMID- 29176616 TI - Current data on extremities chronic osteomyelitis in southwest China: epidemiology, microbiology and therapeutic consequences. AB - The current study was designed to explore the epidemiology of extremities chronic osteomyelitis, its prognosis and the complications of the treatment methods being used in southwest China. The data from osteomyelitis patients treated at the Department of Orthopaedics, Southwest Hospital, China between May 2011 and September 2016 were collected and analysed. The study comprised 503 admitted patients, of which 416 males and 87 were females, with an average age of 40.15 +/ 5.64 years. Approximately 356 cases were followed for more than 18 months; the average bone union time was 6.24 +/- 0.76 months in 94.1% (335) patients, and infections were almost controlled in 93.8% patients. The rate of infection control with the induced membrane technique was higher than with the I-stage free bone graft. Iliac infection was the main complication of the induced membrane technique, and impaired joint activity was the main complication of I-stage free bone grafts. In southwest China, the incidence of haematogenous osteomyelitis, caused mainly by Staphylococcus aureus, remains very high. The speed of bone defect repair and the rate of infection control with the induced membrane technique were superior to those of I-stage free bone grafts. Internal fixation should be given priority because it offers reduced complications with no increase in the recurrence of infection. PMID- 29176617 TI - Thae use of microfluic spinning fiber as an ophthalmology suture showing the good anastomotic strength control. AB - Adjusting the mechanical strength of a biomaterial to suit its intended application is very important for realizing beneficial outcomes. Microfluidic spinning fiber have been attracting attention recently due to their various advantages, but their mechanical strength has unfortunately not been a subject of concentrated research, and this lack of research has severely limited their applications. In the current work, we showed the mechanical properties of microfibers can be tuned easily and provided a mathematical explanation for how the microfluidic spinning method intrinsically controls the mechanical properties of a microfluidic spinning fiber. But we were also able to adjust the mechanical properties of such fibers in various other ways, including by using biomolecules to coat the fiber or mixing the biomolecules with the primary component of the fiber and by using a customized twisting machine to change the number of single microfiber strands forming the fiber. We used the bundle fiber as an ophthalmology suture that resulted in a porcine eye with a smoother post operative surface than did a nylon suture. The results showed the possibility that the proposed method can solve current problems of the microfibers in practical applications, and can thus extend the range of applications of these microfibers. PMID- 29176618 TI - Degradation Mechanism of Ag Nanorods for Surface Enhanced Raman Spectroscopy. AB - This paper reports a degradation mechanism of silver (Ag) nanorods that are used as substrates for surface enhanced Raman spectroscopy (SERS). The attachment of sulfur and hydrocarbons to the surfaces of Ag nanorods is observed when they are stored in ambient over four months. This attachment is observed to correlate with ~20% decrease in SERS signal. The attachment, and thereby the signal degradation, takes three weeks to complete, and remains stable after the initial decay over the rest of the four month test period. While this degradation mechanism is a limitation to the gross enhancement, the ensuing stability beyond three weeks is encouraging. PMID- 29176621 TI - Wind-generated Electricity in China: Decreasing Potential, Inter-annual Variability and Association with Changing Climate. AB - China hosts the world's largest market for wind-generated electricity. The financial return and carbon reduction benefits from wind power are sensitive to changing wind resources. Wind data derived from an assimilated meteorological database are used here to estimate what the wind generated electricity in China would have been on an hourly basis over the period 1979 to 2015 at a geographical resolution of approximately 50 km * 50 km. The analysis indicates a secular decrease in generating potential over this interval, with the largest declines observed for western Inner Mongolia (15 +/- 7%) and the northern part of Gansu (17 +/- 8%), two leading wind investment areas. The decrease is associated with long-term warming in the vicinity of the Siberian High (SH), correlated also with the observed secular increase in global average surface temperatures. The long term trend is modulated by variability relating to the Pacific Decadal Oscillation (PDO) and the Arctic Oscillation (AO). A linear regression model incorporating indices for the PDO and AO, as well as the declining trend, can account for the interannual variability of wind power, suggesting that advances in long-term forecasting could be exploited to markedly improve management of future energy systems. PMID- 29176619 TI - STIM1 promotes migration, phagosomal maturation and antigen cross-presentation in dendritic cells. AB - Antigen cross-presentation by dendritic cells (DC) stimulates cytotoxic T cell activation to promote immunity to intracellular pathogens, viruses and cancer. Phagocytosed antigens generate potent T cell responses, but the signalling and trafficking pathways regulating their cross-presentation are unclear. Here, we show that ablation of the store-operated-Ca2+-entry regulator STIM1 in mouse myeloid cells impairs cross-presentation and DC migration in vivo and in vitro. Stim1 ablation reduces Ca2+ signals, cross-presentation, and chemotaxis in mouse bone-marrow-derived DCs without altering cell differentiation, maturation or phagocytic capacity. Phagosomal pH homoeostasis and ROS production are unaffected by STIM1 deficiency, but phagosomal proteolysis and leucyl aminopeptidase activity, IRAP recruitment, as well as fusion of phagosomes with endosomes and lysosomes are all impaired. These data suggest that STIM1-dependent Ca2+ signalling promotes the delivery of endolysosomal enzymes to phagosomes to enable efficient cross-presentation. PMID- 29176620 TI - Cellular microRNA networks regulate host dependency of hepatitis C virus infection. AB - Cellular microRNAs (miRNAs) have been shown to regulate hepatitis C virus (HCV) replication, yet a systematic interrogation of the repertoire of miRNAs impacting HCV life cycle is lacking. Here we apply integrative functional genomics strategies to elucidate global HCV-miRNA interactions. Through genome-wide miRNA mimic and hairpin inhibitor phenotypic screens, and miRNA-mRNA transcriptomics analyses, we identify three proviral and nine antiviral miRNAs that interact with HCV. These miRNAs are functionally linked to particular steps of HCV life cycle and related viral host dependencies. Further mechanistic studies demonstrate that miR-25, let-7, and miR-130 families repress essential HCV co-factors, thus restricting viral infection at multiple stages. HCV subverts the antiviral actions of these miRNAs by dampening their expression in cell culture models and HCV-infected human livers. This comprehensive HCV-miRNA interaction map provides fundamental insights into HCV-mediated pathogenesis and unveils molecular pathways linking RNA biology to viral infections. PMID- 29176623 TI - Microneedle-array patches loaded with dual mineralized protein/peptide particles for type 2 diabetes therapy. AB - The delivery of therapeutic peptides for diabetes therapy is compromised by short half-lives of drugs with the consequent need for multiple daily injections that reduce patient compliance and increase treatment cost. In this study, we demonstrate a smart exendin-4 (Ex4) delivery device based on microneedle (MN) array patches integrated with dual mineralized particles separately containing Ex4 and glucose oxidase (GOx). The dual mineralized particle-based system can specifically release Ex4 while immobilizing GOx as a result of the differential response to the microenvironment induced by biological stimuli. In this manner, the system enables glucose-responsive and closed-loop release to significantly improve Ex4 therapeutic performance. Moreover, integration of mineralized particles can enhance the mechanical strength of alginate-based MN by crosslinking to facilitate skin penetration, thus supporting painless and non invasive transdermal administration. We believe this smart glucose-responsive Ex4 delivery holds great promise for type 2 diabetes therapy by providing safe, long term, and on-demand Ex4 therapy. PMID- 29176624 TI - A statistical image analysis framework for pore-free islands derived from heterogeneity distribution of nuclear pore complexes. AB - Nuclear pore complexes (NPCs) maintain cellular homeostasis by mediating nucleocytoplasmic transport. Although cyclin-dependent kinases (CDKs) regulate NPC assembly in interphase, the location of NPC assembly on the nuclear envelope is not clear. CDKs also regulate the disappearance of pore-free islands, which are nuclear envelope subdomains; this subdomain gradually disappears with increase in homogeneity of the NPC in response to CDK activity. However, a causal relationship between pore-free islands and NPC assembly remains unclear. Here, we elucidated mechanisms underlying NPC assembly from a new perspective by focusing on pore-free islands. We proposed a novel framework for image-based analysis to automatically determine the detailed 'landscape' of pore-free islands from a large quantity of images, leading to the identification of NPC intermediates that appear in pore-free islands with increased frequency in response to CDK activity. Comparison of the spatial distribution between simulated and the observed NPC intermediates within pore-free islands showed that their distribution was spatially biased. These results suggested that the disappearance of pore-free islands is highly related to de novo NPC assembly and indicated the existence of specific regulatory mechanisms for the spatial arrangement of NPC assembly on nuclear envelopes. PMID- 29176625 TI - Silica formation with nanofiber morphology via helical display of the silaffin R5 peptide on a filamentous bacteriophage. AB - Biological systems often generate unique and useful structures, which can have industrial relevance either as direct components or as an inspiration for biomimetic materials. For fabrication of nanoscale silica structures, we explored the use of the silaffin R5 peptide from Cylindrotheca fusiformis expressed on the surface of the fd bacteriophage. By utilizing the biomineralizing peptide component displayed on the bacteriophage surface, we found that low concentrations (0.09 mg/mL of the R5 bacteriophage, below the concentration range used in other studies) could be used to create silica nanofibers. An additional benefit of this approach is the ability of our R5-displaying phage to form silica materials without the need for supplementary components, such as aminopropyl triethoxysilane, that are typically used in such processes. Because this method for silica formation can occur under mild conditions when implementing our R5 displaying phage system, we may provide a relatively simple, economical, and environmentally friendly process for creating silica nanomaterials. PMID- 29176627 TI - Functional anatomy of a giant toothless mandible from a bird-like dinosaur: Gigantoraptor and the evolution of the oviraptorosaurian jaw. AB - The Oviraptorosauria are a group of theropod dinosaurs that diverged from the typical carnivorous theropod diet. It includes two main lineages - Caenagnathidae and Oviraptoridae - that display a number of differences in mandibular morphology, but little is known about their functional consequences, hampering our understanding of oviraptorosaurian dietary evolution. This study presents the first in-depth description of the giant toothless mandible of Gigantoraptor, the only well-preserved stemward caenagnathid mandible. This mandible shows the greatest relative beak depth among caenagnathids, which is an adaptation seen in some modern birds for processing harder seeds. The presence of a lingual triturating shelf in caenagnathids more crownward than Gigantoraptor suggests a possible increased specialization towards shearing along this lineage. Like other oviraptorosaurs, the possession of a dorsally convex articular glenoid in Gigantoraptor indicates that propalinal jaw movement was probably an important mechanism for food processing, as in Sphenodon and dicynodonts. Oviraptorid mandibles were more suited for producing powerful bites (e.g. crushing-related) compared to caenagnathids: oviraptorids generally possess a deeper, more downturned beak, a taller coronoid process prominence and a larger medial mandibular fossa. This disparity in caenagnathid and oviraptorid mandible morphology potentially suggests specialization towards two different feeding styles - shearing and crushing-related mechanisms respectively. PMID- 29176626 TI - Systems genetics identifies a role for Cacna2d1 regulation in elevated intraocular pressure and glaucoma susceptibility. AB - Glaucoma is a multi-factorial blinding disease in which genetic factors play an important role. Elevated intraocular pressure is a highly heritable risk factor for primary open angle glaucoma and currently the only target for glaucoma therapy. Our study helps to better understand underlying genetic and molecular mechanisms that regulate intraocular pressure, and identifies a new candidate gene, Cacna2d1, that modulates intraocular pressure and a promising therapeutic, pregabalin, which binds to CACNA2D1 protein and lowers intraocular pressure significantly. Because our study utilizes a genetically diverse population of mice with known sequence variants, we are able to determine that the intraocular pressure-lowering effect of pregabalin is dependent on the Cacna2d1 haplotype. Using human genome-wide association study (GWAS) data, evidence for association of a CACNA2D1 single-nucleotide polymorphism and primary open angle glaucoma is found. Importantly, these results demonstrate that our systems genetics approach represents an efficient method to identify genetic variation that can guide the selection of therapeutic targets. PMID- 29176628 TI - Identification of the pheromone biosynthesis genes from the sex pheromone gland transcriptome of the diamondback moth, Plutella xylostella. AB - The diamondback moth was estimated to increase costs to the global agricultural economy as the global area increase of Brassica vegetable crops and oilseed rape. Sex pheromones traps are outstanding tools available in Integrated Pest Management for many years and provides an effective approach for DBM population monitoring and control. The ratio of two major sex pheromone compounds shows geographical variations. However, the limitation of our information in the DBM pheromone biosynthesis dampens our understanding of the ratio diversity of pheromone compounds. Here, we constructed a transcriptomic library from the DBM pheromone gland and identified genes putatively involved in the fatty acid biosynthesis, pheromones functional group transfer, and beta-oxidation enzymes. In addition, odorant binding protein, chemosensory protein and pheromone binding protein genes encoded in the pheromone gland transcriptome, suggest that female DBM moths may receive odors or pheromone compounds via their pheromone gland and ovipositor system. Tissue expression profiles further revealed that two ALR, three DES and one FAR5 genes were pheromone gland tissue biased, while some chemoreception genes expressed extensively in PG, pupa, antenna and legs tissues. Finally, the candidate genes from large-scale transcriptome information may be useful for characterizing a presumed biosynthetic pathway of the DBM sex pheromone. PMID- 29176629 TI - Genomic data reveal a loss of diversity in two species of tuco-tucos (genus Ctenomys) following a volcanic eruption. AB - Marked reductions in population size can trigger corresponding declines in genetic variation. Understanding the precise genetic consequences of such reductions, however, is often challenging due to the absence of robust pre- and post-reduction datasets. Here, we use heterochronous genomic data from samples obtained before and immediately after the 2011 eruption of the Puyehue-Cordon Caulle volcanic complex in Patagonia to explore the genetic impacts of this event on two parapatric species of rodents, the colonial tuco-tuco (Ctenomys sociabilis) and the Patagonian tuco-tuco (C. haigi). Previous analyses using microsatellites revealed no post-eruption changes in genetic variation in C. haigi, but an unexpected increase in variation in C. sociabilis. To explore this outcome further, we used targeted gene capture to sequence over 2,000 putatively neutral regions for both species. Our data revealed that, contrary to the microsatellite analyses, the eruption was associated with a small but significant decrease in genetic variation in both species. We suggest that genome-level analyses provide greater power than traditional molecular markers to detect the genetic consequences of population size changes, particularly changes that are recent, short-term, or modest in size. Consequently, genomic analyses promise to generate important new insights into the effects of specific environmental events on demography and genetic variation. PMID- 29176631 TI - Lack of Adipocyte-Fndc5/Irisin Expression and Secretion Reduces Thermogenesis and Enhances Adipogenesis. AB - Irisin is a browning-stimulating molecule secreted from the fibronectin type III domain containing 5 precursor (FNDC5) by muscle tissue upon exercise stimulation. Despite its beneficial role, there is an unmet and clamorous need to discern many essential aspects of this protein and its mechanism of action not only as a myokine but also as an adipokine. Here we contribute to address this topic by revealing the nature and role of FNDC5/irisin in adipose tissue. First, we show that FNDC5/irisin expression and secretion are induced by adipocyte differentiation and confirm its over-secretion by human obese visceral (VAT) and subcutaneous (SAT) adipose tissues. Second, we show how secreted factors from human obese VAT and SAT decrease PGC1alpha, FNDC5 and UCP1 gene expression on differentiating adipocytes; this effect over UCP1 is blunted by blocking irisin in obese secretomes. Finally, by stable gene silencing FNDC5 we reveal that FNDC5 KO adipocytes show reduced UCP1 expression and enhanced adipogenesis. PMID- 29176632 TI - Tuning magnetic properties for domain wall pinning via localized metal diffusion. AB - Precise control of domain wall displacement in nanowires is essential for application in domain wall based memory and logic devices. Currently, domain walls are pinned by creating topographical notches fabricated by lithography. In this paper, we propose localized diffusion of non-magnetic metal into ferromagnetic nanowires by annealing induced mixing as a non-topographical approach to form pinning sites. As a first step to prove this new approach, magnetodynamic properties of permalloy (Ni80Fe20) films coated with different capping layers such as Ta, Cr, Cu and Ru were investigated. Ferromagnetic resonance (FMR), and anisotropy magnetoresistance (AMR) measurements were carried out after annealing the samples at different temperatures (T an ). The saturation magnetization of Ni80Fe20 film decreased, and damping constant increased with T an . X-Ray photoelectron spectroscopy results confirmed increased diffusion of Cr into the middle of Ni80Fe20 layers with T an . The resistance vs magnetic field measurements on nanowires showed intriguing results. PMID- 29176630 TI - Break-induced replication promotes formation of lethal joint molecules dissolved by Srs2. AB - Break-induced replication (BIR) is a DNA double-strand break repair pathway that leads to genomic instabilities similar to those observed in cancer. BIR proceeds by a migrating bubble where asynchrony between leading and lagging strand synthesis leads to accumulation of long single-stranded DNA (ssDNA). It remains unknown how this ssDNA is prevented from unscheduled pairing with the template, which can lead to genomic instability. Here, we propose that uncontrolled Rad51 binding to this ssDNA promotes formation of toxic joint molecules that are counteracted by Srs2. First, Srs2 dislodges Rad51 from ssDNA preventing promiscuous strand invasions. Second, it dismantles toxic intermediates that have already formed. Rare survivors in the absence of Srs2 rely on structure-specific endonucleases, Mus81 and Yen1, that resolve toxic joint-molecules. Overall, we uncover a new feature of BIR and propose that tight control of ssDNA accumulated during this process is essential to prevent its channeling into toxic structures threatening cell viability.

AB - Multicenter, longitudinal studies on nontuberculous mycobacteria (NTM) pulmonary infection (PI) are lacking. This study provides a 5-year epidemiological overview of NTM-PI in Taiwan and investigated its predictors. The clinical relevance of each respiratory NTM isolate in six hospitals between 2008 and 2014 was determined according to current guidelines. Recurrent episodes were judged by serial bacteriological results. New episodes of NTM-PI and pulmonary colonization (PC) occurring since 2010 were analyzed. Logistic regression analysis was performed to identify the predictors of NTM-PI. Between 2010 and 2014, the incidence rate of NTM-PI was 46.0 episodes per 100,000 hospital-based patient years. Mycobacterium avium intracellulare complex (MAC) was predominant in Northern Taiwan, whereas MAC and M. abscessus were copredominant in Southern Taiwan. Multiple episodes occurred in 9.5% of NTM-PI patients. No female predominance was observed, except for MAC-PI. Previous pulmonary tuberculosis and chronic obstructive pulmonary disease (COPD) were the most common pulmonary comorbidities and independent risk factors for NTM-PI. Other risk factors included M. kansasii, M. abscessus, and southern Taiwan. Geographical variation of NTM-PI exists in Taiwan. Clinicians should keep a high suspicion on NTM-PI in the risk population. In endemic area of tuberculosis and COPD, there may be no female predominance in NTM-PI.

AB - In a recent publication we showed that permutation symmetry reduces the numerical complexity of Lindblad quantum master equations for identical multi-level systems from exponential to polynomial scaling. This is important for open system dynamics including realistic system bath interactions and dephasing in, for instance, the Dicke model, multi-Lambda system setups etc. Here we present an object-oriented C++ library that allows to setup and solve arbitrary quantum optical Lindblad master equations, especially those that are permutationally symmetric in the multi-level systems. PsiQuaSP (Permutation symmetry for identical Quantum Systems Package) uses the PETSc package for sparse linear algebra methods and differential equations as basis. The aim of PsiQuaSP is to provide flexible, storage efficient and scalable code while being as user friendly as possible. It is easily applied to many quantum optical or quantum information systems with more than one multi-level system. We first review the basics of the permutation symmetry for multi-level systems in quantum master equations. The application of PsiQuaSP to quantum dynamical problems is illustrated with several typical, simple examples of open quantum optical systems.

AB - Mechanical properties of nanoscale objects can be measured with an atomic force microscope (AFM) tip. However, the continuum models typically used to relate the force measured at a certain indentation depth to quantities such as the elastic modulus, may not be valid at such small scales, where the details of atomistic processes need to be taken into account. On the other hand, molecular dynamics (MD) simulations of nanoindentation, which can offer understanding at an atomistic level, are often performed on systems much smaller than the ones studied experimentally. Here, we present large scale MD simulations of the nanoindentation of single crystal and penta-twinned gold nanorod samples on a silicon substrate, with a spherical diamond AFM tip apex. Both the sample and tip sizes and geometries match commercially available products, potentially linking simulation and experiment. Different deformation mechanisms, involving the creation, migration and annihilation of dislocations are observed depending on the nanorod crystallographic structure and orientation. Using the Oliver-Pharr method, the Young's moduli of the (100) terminated and (110) terminated single crystal nanorods, and the penta-twinned nanorod, have been determined to be 103 +/- 2, 140 +/- 4 and 108 +/- 2 GPa, respectively, which is in good agreement with bending experiments performed on nanowires. PMID- 29176636 TI - Genetic and clinical characteristics in Japanese hereditary breast and ovarian cancer: first report after establishment of HBOC registration system in Japan. AB - The hereditary breast and ovarian cancer (HBOC) registration system of Japan was established by the Japanese HBOC Consortium. The first trial was registered in 2015 in four institutions to which some registration committee members belonged. We analyzed the information of 830 Japanese pedigrees, who underwent BRCA1/2 genetic testing, including mutation carriers with BRCA1 (N = 127) and BRCA2 (N = 115), and their families. The mutation-positive rate was 19.7%. Variants of uncertain significance were found in 6.5% of all individuals subjected to genetic testing for BRCA1/2. Compared to the United States, Japan had a higher mutation positive rate in most categories, except for the groups with male breast cancer. Among the intrinsic subtypes of BRCA1-associated breast cancers, 75.8% were triple-negative. The incidence rate of contralateral breast cancer in BRCA1/2 mutation carriers was 0.99%/year. Among 240 mutation carriers, 26 and 62 patients underwent risk-reducing mastectomy (RRM) and risk-reducing salpingo-oophorectomy (RRSO), respectively; the respective frequencies of occult cancer were 7.1 and 3.2%. Metachronous breast cancer after RRM or peritoneal cancer after RRSO was not observed during the follow-up period. The nationwide registration system began last year and the system enables follow-up analysis in Japan. PMID- 29176637 TI - Coordinated response of the Desulfovibrio desulfuricans 27774 transcriptome to nitrate, nitrite and nitric oxide. AB - The sulfate reducing bacterium Desulfovibrio desulfuricans inhabits both the human gut and external environments. It can reduce nitrate and nitrite as alternative electron acceptors to sulfate to support growth. Like other sulphate reducing bacteria, it can also protect itself against nitrosative stress caused by NO generated when nitrite accumulates. By combining in vitro experiments with bioinformatic and RNA-seq data, metabolic responses to nitrate or NO and how nitrate and nitrite reduction are coordinated with the response to nitrosative stress were revealed. Although nitrate and nitrite reduction are tightly regulated in response to substrate availability, the global responses to nitrate or NO were largely regulated independently. Multiple NADH dehydrogenases, transcription factors of unknown function and genes for iron uptake were differentially expressed in response to electron acceptor availability or nitrosative stress. Amongst many fascinating problems for future research, the data revealed a YtfE orthologue, Ddes_1165, that is implicated in the repair of nitrosative damage. The combined data suggest that three transcription factors coordinate this regulation in which NrfS-NrfR coordinates nitrate and nitrite reduction to minimize toxicity due to nitrite accumulation, HcpR1 serves a global role in regulating the response to nitrate, and HcpR2 regulates the response to nitrosative stress. PMID- 29176638 TI - Recursive Exponentially Weighted N-way Partial Least Squares Regression with Recursive-Validation of Hyper-Parameters in Brain-Computer Interface Applications. AB - A tensor-input/tensor-output Recursive Exponentially Weighted N-Way Partial Least Squares (REW-NPLS) regression algorithm is proposed for high dimension multi-way (tensor) data treatment and adaptive modeling of complex processes in real-time. The method unites fast and efficient calculation schemes of the Recursive Exponentially Weighted PLS with the robustness of tensor-based approaches. Moreover, contrary to other multi-way recursive algorithms, no loss of information occurs in the REW-NPLS. In addition, the Recursive-Validation method for recursive estimation of the hyper-parameters is proposed instead of conventional cross-validation procedure. The approach was then compared to state of-the-art methods. The efficiency of the methods was tested in electrocorticography (ECoG) and magnetoencephalography (MEG) datasets. The algorithms are implemented in software suitable for real-time operation. Although the Brain-Computer Interface applications are used to demonstrate the methods, the proposed approaches could be efficiently used in a wide range of tasks beyond neuroscience uniting complex multi-modal data structures, adaptive modeling, and real-time computational requirements. PMID- 29176639 TI - Enhancement of Power Output by using Alginate Immobilized Algae in Biophotovoltaic Devices. AB - We report for the first time a photosynthetically active algae immobilized in alginate gel within a fuel cell design for generation of bioelectricity. The algal-alginate biofilm was utilized within a biophotovoltaics (BPV) device developed for direct bioelectricity generation from photosynthesis. A peak power output of 0.289 mWm-2 with an increase of 18% in power output compared to conventional suspension culture BPV device was observed. The increase in maximum power density was correlated to the maximum relative electron transport rate (rETRm). The semi-dry type of photosynthetically active biofilm proposed in this work may offer significantly improved performances in terms of fuel cell design, bioelectricity generation, oxygen production and CO2 reduction. PMID- 29176640 TI - Identification of differentially expressed miRNAs in the fatty liver of Landes goose (Anser anser). AB - Unlike mammals, in palmipedes de novo lipogenesis from diet takes place mostly in the liver. The French Landes Goose is famous for its high capacity and susceptibility to fatty liver production. While miRNAs play a critical role in the posttranscriptional regulation of gene expression, miRNAs that are involved in the regulation of goose hepatic steatosis have yet to be elucidated. Using high-throughput sequencing, we analyzed miRNAs expression profile of Landes goose liver after overfeeding for 21 days. Aan-miR-122-5p was the most frequently sequenced known miRNA, but it was unchanged after overfeeding. Compared with normal liver, we identified that 16 conserved miRNAs were up-regulated while the other 9 conserved miRNAs were down-regulated in fatty livers. Many of their predicted target genes played key roles in metabolic pathways leading to the development of hepatic steatosis in the goose by KEGG pathways analysis. ACSL1 and ELOVL6 were critical genes in hepatic lipid metabolism and had opposite expression patterns with aan-miR-203a and aan-miR-125b-5p, respectively. And we validated that aan-miR-203a and aan-miR-125b-5p might involve in the regulation of hepatic lipid metabolism by targeting ACSL1 and ELOVL6, respectively. These results add to our current understanding of the regulation network in goose lipid metabolism. PMID- 29176641 TI - Anaerobic microsites have an unaccounted role in soil carbon stabilization. AB - Soils represent the largest carbon reservoir within terrestrial ecosystems. The mechanisms controlling the amount of carbon stored and its feedback to the climate system, however, remain poorly resolved. Global carbon models assume that carbon cycling in upland soils is entirely driven by aerobic respiration; the impact of anaerobic microsites prevalent even within well-drained soils is missed within this conception. Here, we show that anaerobic microsites are important regulators of soil carbon persistence, shifting microbial metabolism to less efficient anaerobic respiration, and selectively protecting otherwise bioavailable, reduced organic compounds such as lipids and waxes from decomposition. Further, shifting from anaerobic to aerobic conditions leads to a 10-fold increase in volume-specific mineralization rate, illustrating the sensitivity of anaerobically protected carbon to disturbance. The vulnerability of anaerobically protected carbon to future climate or land use change thus constitutes a yet unrecognized soil carbon-climate feedback that should be incorporated into terrestrial ecosystem models. PMID- 29176642 TI - Insight into partial agonism by observing multiple equilibria for ligand-bound and Gs-mimetic nanobody-bound beta1-adrenergic receptor. AB - A complex conformational energy landscape determines G-protein-coupled receptor (GPCR) signalling via intracellular binding partners (IBPs), e.g., Gs and beta arrestin. Using 13C methyl methionine NMR for the beta1-adrenergic receptor, we identify ligand efficacy-dependent equilibria between an inactive and pre-active state and, in complex with Gs-mimetic nanobody, between more and less active ternary complexes. Formation of a basal activity complex through ligand-free nanobody-receptor interaction reveals structural differences on the cytoplasmic receptor side compared to the full agonist-bound nanobody-coupled form, suggesting that ligand-induced variations in G-protein interaction underpin partial agonism. Significant differences in receptor dynamics are observed ranging from rigid nanobody-coupled states to extensive MUs-to-ms timescale dynamics when bound to a full agonist. We suggest that the mobility of the full agonist-bound form primes the GPCR to couple to IBPs. On formation of the ternary complex, ligand efficacy determines the quality of the interaction between the rigidified receptor and an IBP and consequently the signalling level. PMID- 29176643 TI - Development of a quantitative NS1-capture enzyme-linked immunosorbent assay for early detection of yellow fever virus infection. AB - Yellow fever is an arboviral disease that causes thousands of deaths every year in Africa and the Americas. However, few commercial diagnostic kits are available. Non-structural protein 1 (NS1) is an early marker of several flavivirus infections and is widely used to diagnose dengue virus (DENV) infection. Nonetheless, little is known about the dynamics of Yellow fever virus (YFV) NS1 expression and secretion, to encourage its use in diagnosis. To tackle this issue, we developed a quantitative NS1-capture ELISA specific for YFV using a monoclonal antibody and recombinant NS1 protein. This test was used to quantify NS1 in mosquito and human cell line cultures infected with vaccine and wild YFV strains. Our results showed that NS1 was detectable in the culture supernatants of both cell lines; however, a higher concentration was maintained as cell associated rather than secreted into the extracellular milieu. A panel of 73 human samples was used to demonstrate the suitability of YFV NS1 as a diagnostic tool, resulting in 80% sensitivity, 100% specificity, a 100% positive predictive value and a 95.5% negative predictive value compared with RT-PCR. Overall, the developed NS1-capture ELISA showed potential as a promising assay for the detection of early YF infection.

PMID- 29176645 TI - T cell receptor beta-chains display abnormal shortening and repertoire sharing in type 1 diabetes. AB - Defects in T cell receptor (TCR) repertoire are proposed to predispose to autoimmunity. Here we show, by analyzing >2 * 108 TCRB sequences of circulating naive, central memory, regulatory and stem cell-like memory CD4+ T cell subsets from patients with type 1 diabetes and healthy donors, that patients have shorter TCRB complementarity-determining region 3s (CDR3), in all cell subsets, introduced by increased deletions/reduced insertions during VDJ rearrangement. High frequency of short CDR3s is also observed in unproductive TCRB sequences, which are not subjected to thymic culling, suggesting that the shorter CDR3s arise independently of positive/negative selection. Moreover, TCRB CDR3 clonotypes expressed by autoantigen-specific CD4+ T cells are shorter compared with anti-viral T cells, and with those from healthy donors. Thus, early events in thymic T cell development and repertoire generation are abnormal in type 1 diabetes, which suggest that short CDR3s increase the potential for self recognition, conferring heightened risk of autoimmune disease. PMID- 29176646 TI - An Open Software Platform for the Automated Design of Paper-Based Microfluidic Devices. AB - Paper-based microfluidic devices have many applications in biomedical and environmental analysis. However, the process of prototyping device designs can be tedious, error-prone, and time-consuming. Here, we present a cross-platform, open source software tool-AutoPAD-developed to quickly create and modify device designs and provide a free alternative to commercial design software. The capabilities that we designed to be inherent to AutoPAD (e.g., automatic zone alignment and design refactoring) highlight its potential use in nearly any paper based microfluidic device application and for creating nearly any desired design, which we demonstrate through the recreation of numerous device designs from the literature. PMID- 29176647 TI - MRI Simulation Study Investigating Effects of Vessel Topology, Diffusion, and Susceptibility on Transverse Relaxation Rates Using a Cylinder Fork Model. AB - Brain vasculature is conventionally represented as straight cylinders when simulating blood oxygenation level dependent (BOLD) contrast effects in functional magnetic resonance imaging (fMRI). In reality, the vasculature is more complicated with branching and coiling especially in tumors. Diffusion and susceptibility changes can also introduce variations in the relaxation mechanisms within tumors. This study introduces a simple cylinder fork model (CFM) and investigates the effects of vessel topology, diffusion, and susceptibility on the transverse relaxation rates R2* and R2. Simulations using Monte Carlo methods were performed to quantify R2* and R2 by manipulating the CFM at different orientations, bifurcation angles, and rotation angles. Other parameters of the CFM were chosen based on physiologically relevant values: vessel diameters (~2-10 um), diffusion rates (1 * 10-11-1 * 10-9 m2/s), and susceptibility values (3 * 10 8-4 * 10-7 cgs units). R2* and R2 measurements showed a significant dependence on the bifurcation and rotation angles in several scenarios using different vessel diameters, orientations, diffusion rates, and susceptibility values. The angular dependence of R2* and R2 using the CFM could potentially be exploited as a tool to differentiate between normal and tumor vessels. The CFM can also serve as the elementary building block to simulate a capillary network reflecting realistic topological features. PMID- 29176648 TI - Evidence for PII with NAGK interaction that regulates Arg synthesis in the microalga Myrmecia incisa in response to nitrogen starvation. AB - To understand why most eukaryotic microalgae accumulate lipids during nitrogen starvation stress, a gene, MiglnB, encoding PII, a signal transduction protein, was cloned from the arachidonic acid-rich microalga Myrmecia incisa Reisigl. Similarly to its homologues, MiPII contains three conserved T-, B-, and C-loops. In the presence of abundant Mg2+, ATP, and Gln, MiPII upregulates Arg biosynthesis by interacting with the rate-limiting enzyme, MiNAGK, as evidenced by yeast two-hybrid, co-immunoprecipitation assays, and kinetics analysis of enzyme-catalyzed reactions. However, this interaction of MiPII with MiNAGK is reversed by addition of 2-oxoglutarate (2-OG). Moreover, this interaction is present in the chloroplasts of M. incisa, as illustrated cytologically by both immunoelectron microscopy and agroinfiltration of Nicotiana benthamiana leaves to determine the subcellular localization of MiPII with MiNAGK. During the process of nitrogen starvation, soluble Arg levels in M. incisa are modulated by a change in MiNAGK enzymatic activity, both of which are significantly correlated (r = 0.854). A model for the manipulation of Arg biosynthesis via MiPII in M. incisa chloroplasts in response to nitrogen starvation is proposed. The ATP and 2-OG saved from Arg biosynthesis is thus suggested to facilitate the accumulation of fatty acids and triacylglycerol in M. incisa during exposure to nitrogen starvation. PMID- 29176649 TI - No evidence for social immunity in co-founding queen associations. AB - Ant queens often associate to found new colonies, yet the benefits of this behaviour remain unclear. A major hypothesis is that queens founding in groups are protected by social immunity and can better resist disease than solitary queens, due to mutual grooming, sharing of antimicrobials, or higher genetic diversity among their workers. We tested this hypothesis by manipulating the number of queens in incipient colonies of Lasius niger and measuring their resistance to the fungal entomopathogen Metarhizium brunneum. We found no evidence for social immunity in associations of founding queens. First, co founding queens engaged in self-grooming, but performed very little allo-grooming or trophallaxis. Second, co-founding queens did not exhibit higher pathogen resistance than solitary queens, and their respective workers did not differ in disease resistance. Finally, queens founding in groups increased their investment in a component of individual immunity, as expected if they do not benefit from social immunity but respond to a higher risk of disease. Overall, our results provide no evidence that joint colony founding by L. niger queens increases their ability to resist fungal pathogens. PMID- 29176650 TI - Association of rs6983267 at 8q24, HULC rs7763881 polymorphisms and serum lncRNAs CCAT2 and HULC with colorectal cancer in Egyptian patients. AB - The impact of HULC rs7763881 on colorectal cancer (CRC) susceptibility is not yet known. Also, the biological function of the cancer-related rs6983267 remains unclear. We investigated the association of these SNPs with the risk of CRC and adenomatous polyps (AP), their correlation with CCAT2 and HULC expression, and the potential of serum CCAT2 and HULC as biomarkers for CRC. 120 CRC patients, 30 AP patients, and 96 healthy controls were included. Genotyping and serum lncRNAs were assayed by qPCR. Studied SNPs were not associated with AP susceptibility. rs6983267 GG was associated with increased CRC risk, whereas rs7763881 AC was protective. rs7763881 and rs6983267 CT haplotype was protective. Serum CCAT2 and HULC were upregulated in CRC and AP patients versus controls and discriminated these groups by ROC analysis. rs6983267 GG and rs7763881 AA patients demonstrated higher serum CCAT2 and HULC compared with GT/TT and AC, respectively. rs6983267 and serum HULC predicted CRC diagnosis among non-CRC groups (AP + controls) by multivariate analysis. Studied SNPs or serum long noncoding RNAs weren't correlated with nodal or distant metastasis. In conclusion, rs6983267 and rs7763881 are potential genetic markers of CRC predisposition and correlate with serum CCAT2 and HULC, two novel potential non-invasive diagnostic biomarkers for CRC. PMID- 29176651 TI - Exosomal cargo including microRNA regulates sensory neuron to macrophage communication after nerve trauma. AB - Following peripheral axon injury, dysregulation of non-coding microRNAs (miRs) occurs in dorsal root ganglia (DRG) sensory neurons. Here we show that DRG neuron cell bodies release extracellular vesicles, including exosomes containing miRs, upon activity. We demonstrate that miR-21-5p is released in the exosomal fraction of cultured DRG following capsaicin activation of TRPV1 receptors. Pure sensory neuron-derived exosomes released by capsaicin are readily phagocytosed by macrophages in which an increase in miR-21-5p expression promotes a pro inflammatory phenotype. After nerve injury in mice, miR-21-5p is upregulated in DRG neurons and both intrathecal delivery of a miR-21-5p antagomir and conditional deletion of miR-21 in sensory neurons reduce neuropathic hypersensitivity as well as the extent of inflammatory macrophage recruitment in the DRG. We suggest that upregulation and release of miR-21 contribute to sensory neuron-macrophage communication after damage to the peripheral nerve. PMID- 29176652 TI - A Distinct Endocytic Mechanism of Functionalized-Silica Nanoparticles in Breast Cancer Stem Cells. AB - Nanoparticles provide new fields for life medical science application, including targeted-drug delivery and cancer treatment. To maximize the delivery efficiency of nanoparticle, one must understand the uptake mechanism of nanoparticle in cells, which may determine their ultimate fate and localization in cells. Recently, the proposed-cancer stem cell (CSC) theory has been attracted great attention and regarded as new targets for the new nanodrug developmet and cancer therapies. The interaction between nanoparticles and cancer cells has been extensively studied, but the uptake mechanism of nanoparticles in CSCs has received little attention. Here, we use the pharmacological inhibitors of major endocytic pathways to study the silica nanoparticle (SiNP) uptake mechanisms in the human breast adenocarcinoma cell line (MCF-7) and MCF-7-derived breast cancer stem cells (BCSCs). The results demonstrate that the uptake of SiNPs, particularly amino-functionalized SiNPs, in MCF-7 cells is strongly affected by the actin depolymerization, whereas BCSCs more strongly inhibit the amino functionalized SiNP uptake after the scavenger receptor disruption. These findings indicate a distinct endocytic mechanism of functionalized SiNPs in BCSCs, which is significant for designing ideal nanosized drug delivery systems and improving the selectivity for CSC-targeted therapy. PMID- 29176653 TI - Estrogen induces c-Kit and an aggressive phenotype in a model of invasive lobular breast cancer. AB - Among the molecular subtypes of breast cancer are luminal (A or B) estrogen receptor positive (ER+), HER2+, and triple negative (basal-like). In addition to the molecular subtypes, there are 18 histologic breast cancer subtypes classified on appearance, including invasive lobular breast carcinoma (ILC), which are 8-15% of all breast cancers and are largely ER+ tumors. We used a new model of ER+ ILC, called BCK4. To determine the estrogen regulated genes in our ILC model, we examined BCK4 xenograft tumors from mice supplemented with or without estrogen using gene expression arrays. Approximately 3000 genes were regulated by estrogen in vivo. Hierarchical cluster analyses of the BCK4 derived tumors compared with ER+ and ER- breast cancer cell lines show the estrogen treated BCK4 tumors group with ER- breast cancers most likely due to a high proliferation score, while tumors from cellulose supplemented mice were more related to ER+ breast tumor cells. To elucidate genes regulated in vitro by estrogen in BCK4 cells, we performed expression profiling using Illumina arrays of the BCK4 cell line, treated with or without estrogen in vitro. A set of ~200 overlapping genes were regulated by estrogen in the BCK4 cell line and xenograft tumors, and pathway analysis revealed that the c-Kit pathway might be a target to reduce estrogen induced proliferation. Subsequent studies found that inhibition of c-Kit activity using imatinib mesylate (Gleevec(r)) blocked estrogen mediated stimulation of BCK4 tumors and BCK4 cells in vitro as effectively as the anti-estrogen fulvestrant (Faslodex(r)). Decreased expression of c-Kit using shRNA also decreased baseline and estrogen induced proliferation in vitro and in vivo. These studies are the first to indicate that c-Kit inhibition is an effective approach to target c-Kit+ ILC. PMID- 29176654 TI - Programmed biomolecule delivery to enable and direct cell migration for connective tissue repair. AB - Dense connective tissue injuries have limited repair, due to the paucity of cells at the wound site. We hypothesize that decreasing the density of the local extracellular matrix (ECM) in conjunction with releasing chemoattractive signals increases cellularity and tissue formation after injury. Using the knee meniscus as a model system, we query interstitial cell migration in the context of migratory barriers using a novel tissue Boyden chamber and show that a gradient of platelet-derived growth factor-AB (PDGF-AB) expedites migration through native tissue. To implement these signals in situ, we develop nanofibrous scaffolds with distinct fiber fractions that sequentially release active collagenase (to increase ECM porosity) and PDGF-AB (to attract endogenous cells) in a localized and coordinated manner. We show that, when placed into a meniscal defect, the controlled release of collagenase and PDGF-AB increases cellularity at the interface and within the scaffold, as well as integration with the surrounding tissue. PMID- 29176655 TI - Incidence and risk of respiratory tract infection associated with specific drug therapy in pulmonary arterial hypertension: a systematic review. AB - Specific drug therapy has been proven to improve functional capacity and slow disease progression in pulmonary arterial hypertension (PAH), regretfully with the data on the risk of respiratory tract infection (RTI) associated with specific drug therapy being limited. Databases of Medline, Embase, Cochrane Library and the ClinicalTrials.gov Website were searched for randomized controlled trials (RCTs) that reported the RTI data of PAH-specific drug therapy in patients. The primacy outcome was assessed by employing a fixed-effects model. Totally, 24 trials involving 6307 patients were included in the analysis. PAH specific drug therapy was not significantly associated with the increased risk of both RTI (19.4% vs. 21.1% RR 1.02, 95%CI 0.92-1.14, P = 0.69) and serious RTI (4.3% vs. 5.0% RR 0.99, 95%CI 0.77-1.26, P = 0.93) compared to placebo. The results were consistent across the key subgroups. No heterogeneity between the studies (I2 = 35.8% for RTI, and I2 = 0.0% for serious RTI) and no publication bias was identified. In conclusion, no significant increase in RTI had been found in PAH-specific drug therapy when compared with placebo. Whereas, RTI in PAH patients is still worthy of clinical attention.

PMID- 29176659 TI - Non-destructive evaluation of UV pulse laser-induced damage performance of fused silica optics. AB - The surface laser damage performance of fused silica optics is related to the distribution of surface defects. In this study, we used chemical etching assisted by ultrasound and magnetorheological finishing to modify defect distribution in a fused silica surface, resulting in fused silica samples with different laser damage performance. Non-destructive test methods such as UV laser-induced fluorescence imaging and photo-thermal deflection were used to characterize the surface defects that contribute to the absorption of UV laser radiation. Our results indicate that the two methods can quantitatively distinguish differences in the distribution of absorptive defects in fused silica samples subjected to different post-processing steps. The percentage of fluorescence defects and the weak absorption coefficient were strongly related to the damage threshold and damage density of fused silica optics, as confirmed by the correlation curves built from statistical analysis of experimental data. The results show that non destructive evaluation methods such as laser-induced fluorescence and photo thermal absorption can be effectively applied to estimate the damage performance of fused silica optics at 351 nm pulse laser radiation. This indirect evaluation method is effective for laser damage performance assessment of fused silica optics prior to utilization. PMID- 29176657 TI - Dyslipidaemia in nephrotic syndrome: mechanisms and treatment. AB - Nephrotic syndrome is a highly prevalent disease that is associated with high morbidity despite notable advances in its treatment. Many of the complications of nephrotic syndrome, including the increased risk of atherosclerosis and thromboembolism, can be linked to dysregulated lipid metabolism and dyslipidaemia. These abnormalities include elevated plasma levels of cholesterol, triglycerides and the apolipoprotein B-containing lipoproteins VLDL and IDL; decreased lipoprotein lipase activity in the endothelium, muscle and adipose tissues; decreased hepatic lipase activity; and increased levels of the enzyme PCSK9. In addition, there is an increase in the plasma levels of immature HDL particles and reduced cholesterol efflux. Studies from the past few years have markedly improved our understanding of the molecular pathogenesis of nephrotic syndrome-associated dyslipidaemia, and also heightened our awareness of the associated exacerbated risks of cardiovascular complications, progressive kidney disease and thromboembolism. Despite the absence of clear guidelines regarding treatment, various strategies are being increasingly utilized, including statins, bile acid sequestrants, fibrates, nicotinic acid and ezetimibe, as well as lipid apheresis, which seem to also induce partial or complete clinical remission of nephrotic syndrome in a substantial percentage of patients. Future potential treatments will likely also include inhibition of PCSK9 using recently-developed anti-PCSK9 monoclonal antibodies and small inhibitory RNAs, as well as targeting newly identified molecular regulators of lipid metabolism that are dysregulated in nephrotic syndrome. PMID- 29176661 TI - Stable Hydrothermal Waves at Steady State Evaporating Droplet Surface. AB - Stable hydrothermal waves (HTWs) are found at a sessile ethanol droplet surface under the steady state evaporation. It is different from those which greatly decrease with the evaporation time in the transient droplet drying process. This study removes the possible effect of shrinking droplet on HTWs. An analysis of the dimensionless numbers indicates the increasingly enhanced role of thermocapillary instabilities upon raising the substrate temperature. The onset HTWs can be continuously maintained under the steady state evaporation conditions. Interestingly, the stable number of HTWs follows a linear fitting with the dimensionless factor incorporating the normalized temperature difference between the substrate and the surroundings and the droplet aspect ratio. The temperature heterogeneity of HTWs is intensified by increasing the substrate temperature. The stable HTWs exhibit the "one source-to-one sink" propagation at lower substrate temperatures. However, such directional traveling, normally presented in the transient HTWs in the drying droplet, is changed at the higher substrate temperatures due to the newly emerged sources and sinks under the steady state conditions. PMID- 29176660 TI - Social adversity and epigenetic aging: a multi-cohort study on socioeconomic differences in peripheral blood DNA methylation. AB - Low socioeconomic status (SES) is associated with earlier onset of age-related chronic conditions and reduced life-expectancy, but the underlying biomolecular mechanisms remain unclear. Evidence of DNA-methylation differences by SES suggests a possible association of SES with epigenetic age acceleration (AA). We investigated the association of SES with AA in more than 5,000 individuals belonging to three independent prospective cohorts from Italy, Australia, and Ireland. Low SES was associated with greater AA (beta = 0.99 years; 95% CI 0.39,1.59; p = 0.002; comparing extreme categories). The results were consistent across different SES indicators. The associations were only partially modulated by the unhealthy lifestyle habits of individuals with lower SES. Individuals who experienced life-course SES improvement had intermediate AA compared to extreme SES categories, suggesting reversibility of the effect and supporting the relative importance of the early childhood social environment. Socioeconomic adversity is associated with accelerated epigenetic aging, implicating biomolecular mechanisms that may link SES to age-related diseases and longevity. PMID- 29176663 TI - propr: An R-package for Identifying Proportionally Abundant Features Using Compositional Data Analysis. AB - In the life sciences, many assays measure only the relative abundances of components in each sample. Such data, called compositional data, require special treatment to avoid misleading conclusions. Awareness of the need for caution in analyzing compositional data is growing, including the understanding that correlation is not appropriate for relative data. Recently, researchers have proposed proportionality as a valid alternative to correlation for calculating pairwise association in relative data. Although the question of how to best measure proportionality remains open, we present here a computationally efficient R package that implements three measures of proportionality. In an effort to advance the understanding and application of proportionality analysis, we review the mathematics behind proportionality, demonstrate its application to genomic data, and discuss some ongoing challenges in the analysis of relative abundance data. PMID- 29176662 TI - Minimal residual disease by either flow cytometry or cytogenetics prior to an allogeneic hematopoietic stem cell transplant is associated with poor outcome in acute myeloid leukemia. AB - Relapsed acute myeloid leukemia (AML) is a significant challenge after allogeneic hematopoietic cell transplant (HCT). Multiparameter flow cytometry (MFC), conventional cytogenetics (CG), and fluorescence in situ hybridization (FISH) are routinely performed on bone marrow specimens prior to HCT to assess disease status. We questioned the extent by which pre-HCT evidence of minimal residual disease (MRD) detected by these standard assays, corresponded with post-HCT relapse. We conducted a single center, retrospective study of 166 AML patients who underwent HCT. Thirty-eight of one hundred sixty-six (23%) patients in complete remission (CR) or CR with incomplete count recovery (CRi) had MRD detectable by MFC, CG, or FISH. MRD was more frequently seen in patients with poor risk karyotype at diagnosis (P = 0.011). MRD-negative patients (MRDneg) had significantly longer overall survival (OS) and relapse-free survival than patients who were MRD positive (MRDpos) (P = 0.002 and 0.013, respectively). In patients with MRDpos prior to HCT, the presence of acute graft vs. host disease (GVHD) (grade >= 2) or chronic GVHD significantly improved progression free survival (PFS) (hazard ratio (HR) = 0.053 (95% confidence interval (CI): 0.01 0.279), P = 0.0005) and OS (HR = 0.211 (95% CI: 0.081-0.547), P = 0.0014). PMID- 29176664 TI - GABAA receptor dependent synaptic inhibition rapidly tunes KCC2 activity via the Cl--sensitive WNK1 kinase. AB - The K+-Cl- co-transporter KCC2 (SLC12A5) tunes the efficacy of GABAA receptor mediated transmission by regulating the intraneuronal chloride concentration [Cl ]i. KCC2 undergoes activity-dependent regulation in both physiological and pathological conditions. The regulation of KCC2 by synaptic excitation is well documented; however, whether the transporter is regulated by synaptic inhibition is unknown. Here we report a mechanism of KCC2 regulation by GABAA receptor (GABAAR)-mediated transmission in mature hippocampal neurons. Enhancing GABAAR mediated inhibition confines KCC2 to the plasma membrane, while antagonizing inhibition reduces KCC2 surface expression by increasing the lateral diffusion and endocytosis of the transporter. This mechanism utilizes Cl- as an intracellular secondary messenger and is dependent on phosphorylation of KCC2 at threonines 906 and 1007 by the Cl--sensing kinase WNK1. We propose this mechanism contributes to the homeostasis of synaptic inhibition by rapidly adjusting neuronal [Cl-]i to GABAAR activity. PMID- 29176666 TI - Depth accuracy of the RealSense F200: Low-cost 4D facial imaging. AB - The RealSense F200 represents a new generation of economically viable 4 dimensional imaging (4D) systems for home use. However, its 3D geometric (depth) accuracy has not been clinically tested. Therefore, this study determined the depth accuracy of the RealSense, in a cohort of patients with a unilateral facial palsy (n = 34), by using the clinically validated 3dMD system as a gold standard. The patients were simultaneously recorded with both systems, capturing six Sunnybrook poses. This study has shown that the RealSense depth accuracy was not affected by a facial palsy (1.48 +/- 0.28 mm), compared to a healthy face (1.46 +/- 0.26 mm). Furthermore, the Sunnybrook poses did not influence the RealSense depth accuracy (p = 0.76). However, the distance of the patients to the RealSense was shown to affect the accuracy of the system, where the highest depth accuracy of 1.07 mm was measured at a distance of 35 cm. Overall, this study has shown that the RealSense can provide reliable and accurate depth data when recording a range of facial movements. Therefore, when the portability, low-costs, and availability of the RealSense are taken into consideration, the camera is a viable option for 4D close range imaging in telehealth. PMID- 29176665 TI - Microbial volatile communication in human organotypic lung models. AB - We inhale respiratory pathogens continuously, and the subsequent signaling events between host and microbe are complex, ultimately resulting in clearance of the microbe, stable colonization of the host, or active disease. Traditional in vitro methods are ill-equipped to study these critical events in the context of the lung microenvironment. Here we introduce a microscale organotypic model of the human bronchiole for studying pulmonary infection. By leveraging microscale techniques, the model is designed to approximate the structure of the human bronchiole, containing airway, vascular, and extracellular matrix compartments. To complement direct infection of the organotypic bronchiole, we present a clickable extension that facilitates volatile compound communication between microbial populations and the host model. Using Aspergillus fumigatus, a respiratory pathogen, we characterize the inflammatory response of the organotypic bronchiole to infection. Finally, we demonstrate multikingdom, volatile-mediated communication between the organotypic bronchiole and cultures of Aspergillus fumigatus and Pseudomonas aeruginosa. PMID- 29176667 TI - Mesenchymal stem cells derived exosomes and microparticles protect cartilage and bone from degradation in osteoarthritis. AB - Mesenchymal stem or stromal cells (MSCs) exert chondroprotective effects in preclinical models of osteoarthritis (OA). Most of their therapeutic effects are mediated via soluble mediators, which can be conveyed within extracellular vesicles (EVs). The objective of the study was to compare the respective role of exosomes (Exos) or microvesicles/microparticles (MPs) in OA. MPs and Exos were isolated from bone marrow murine BM-MSCs through differential centrifugation. Effect of MPs or Exos was evaluated on OA-like murine chondrocytes and chondroprotection was quantified by RT-qPCR. In OA-like chondrocytes, BM-MSC derived MPs and Exos could reinduce the expression of chondrocyte markers (type II collagen, aggrecan) while inhibiting catabolic (MMP-13, ADAMTS5) and inflammatory (iNOS) markers. Exos and MPs were also shown to protect chondrocytes from apoptosis and to inhibit macrophage activation. In vivo, Exos or MPs were injected in the collagenase-induced OA (CIOA) model and histomorphometric analyses of joints were performed by uCT and confocal laser microscopy. BM-MSCs, MPs and Exos equally protected mice from joint damage. In conclusion, MPs and Exos exerted similar chondroprotective and anti-inflammatory function in vitro and protected mice from developing OA in vivo, suggesting that either Exos or MPs reproduced the main therapeutic effect of BM-MSCs. PMID- 29176668 TI - A protein interaction mechanism for suppressing the mechanosensitive Piezo channels. AB - Piezo proteins are bona fide mammalian mechanotransduction channels for various cell types including endothelial cells. The mouse Piezo1 of 2547 residues forms a three-bladed, propeller-like homo-trimer comprising a central pore-module and three propeller-structures that might serve as mechanotransduction-modules. However, the mechanogating and regulation of Piezo channels remain unclear. Here we identify the sarcoplasmic /endoplasmic-reticulum Ca2+ ATPase (SERCA), including the widely expressed SERCA2, as Piezo interacting proteins. SERCA2 strategically suppresses Piezo1 via acting on a 14-residue-constituted intracellular linker connecting the pore-module and mechanotransduction-module. Mutating the linker impairs mechanogating and SERCA2-mediated modulation of Piezo1. Furthermore, the synthetic linker-peptide disrupts the modulatory effects of SERCA2, demonstrating the key role of the linker in mechanogating and regulation. Importantly, the SERCA2-mediated regulation affects Piezo1-dependent migration of endothelial cells. Collectively, we identify SERCA-mediated regulation of Piezos and the functional significance of the linker, providing important insights into the mechanogating and regulation mechanisms of Piezo channels. PMID- 29176669 TI - Modulation of individual auditory-motor coordination dynamics through interpersonal visual coupling. AB - The current study investigated whether visual coupling between two people producing dance-related movements (requiring whole-body auditory-motor coordination) results in interpersonal entrainment and modulates individual auditory-motor coordination dynamics. Paired participants performed two kinds of coordination tasks - either knee flexion or extension repeatedly with metronome beats (Flexion-on-the-beat and Extension-on-the-beat conditions) while standing face-to-face or back-to-back to manipulate visual interaction. The results indicated that the relative phases between paired participants' movements were closer to 0 degrees and less variable when participants could see each other. In addition, visibility of the partner reduced individual differences in the dynamics of auditory-motor coordination by modulating coordination variability and the frequency of phase transitions from Extension-on-the-beat to Flexion-on the-beat. Together, these results indicate that visual coupling takes place when paired participants can see each other and leads to interpersonal entrainment during rhythmic auditory-motor coordination, which compensates for individual differences via behavioural assimilation and thus enables individuals to achieve unified and cohesive performances. PMID- 29176670 TI - Micro-gun based on laser pulse propulsion. AB - This paper proposes a novel "micro-gun" structure for laser pulse propulsion. The "micro-bullets" (glass microspheres) are irradiated by a laser pulse with a 10 ns duration in a dynamic process. Experimental parameters such as the microsphere diameter and the laser pulse energy are varied to investigate their influence on laser pulse propulsion. The energy field and spatial intensity distribution in the capillary tube were simulated using a three-dimensional finite-difference time-domain method. The experimental results demonstrate that the propulsion efficiency is dependent on the laser pulse energy and the microsphere size. The propulsion modes and sources of the propelling force were confirmed through direct observation and theoretical calculation. Waves also generated by light pressure and thermal expansions assisted the propulsion. PMID- 29176671 TI - Inhibition of Delta-induced Notch signaling using fucose analogs. AB - Notch is a cell-surface receptor that controls cell-fate decisions and is regulated by O-glycans attached to epidermal growth factor-like (EGF) repeats in its extracellular domain. Protein O-fucosyltransferase 1 (Pofut1) modifies EGF repeats with O-fucose and is essential for Notch signaling. Constitutive activation of Notch signaling has been associated with a variety of human malignancies. Therefore, tools that inhibit Notch activity are being developed as cancer therapeutics. To this end, we screened L-fucose analogs for their effects on Notch signaling. Two analogs, 6-alkynyl and 6-alkenyl fucose, were substrates of Pofut1 and were incorporated directly into Notch EGF repeats in cells. Both analogs were potent inhibitors of binding to and activation of Notch1 by Notch ligands Dll1 and Dll4, but not by Jag1. Mutagenesis and modeling studies suggest that incorporation of the analogs into EGF8 of Notch1 markedly reduces the ability of Delta ligands to bind and activate Notch1. PMID- 29176672 TI - 5-Formylcytosine to cytosine conversion by C-C bond cleavage in vivo. AB - Tet enzymes oxidize 5-methyl-deoxycytidine (mdC) to 5-hydroxymethyl-dC (hmdC), 5 formyl-dC (fdC) and 5-carboxy-dC (cadC) in DNA. It was proposed that fdC and cadC deformylate and decarboxylate, respectively, to dC over the course of an active demethylation process. This would re-install canonical dC bases at previously methylated sites. However, whether such direct C-C bond cleavage reactions at fdC and cadC occur in vivo remains an unanswered question. Here we report the incorporation of synthetic isotope- and (R)-2'-fluorine-labeled dC and fdC derivatives into the genome of cultured mammalian cells. Following the fate of these probe molecules using UHPLC-MS/MS provided quantitative data about the formed reaction products. The data show that the labeled fdC probe is efficiently converted into the corresponding labeled dC, most likely after its incorporation into the genome. Therefore, we conclude that fdC undergoes C-C bond cleavage in stem cells, leading to the direct re-installation of unmodified dC. PMID- 29176673 TI - Phosphoproteomics of cAMP signaling of Bordetella adenylate cyclase toxin in mouse dendritic cells. AB - The adenylate cyclase toxin (CyaA) of the whooping cough agent Bordetella pertussis subverts immune functions of host myeloid cells expressing the alphaMbeta2 integrin (CD11b/CD18, CR3 or Mac-1). CyaA delivers into cytosol of cells an extremely catalytically active adenylyl cyclase enzyme, which disrupts the innate and adaptive immune functions of phagocytes through unregulated production of the key signaling molecule cAMP. We have used phosphoproteomics to analyze cAMP signaling of CyaA in murine bone marrow-derived dendritic cells. CyaA action resulted in alterations of phosphorylation state of a number of proteins that regulate actin cytoskeleton homeostasis, including Mena, Talin-1 and VASP. CyaA action repressed mTOR signaling through activation of mTORC1 inhibitors TSC2 and PRAS40 and altered phosphorylation of multiple chromatin remodelers, including the class II histone deacetylase HDAC5. CyaA toxin action further elicited inhibitory phosphorylation of SIK family kinases involved in modulation of immune response and provoked dephosphorylation of the transcriptional coactivator CRTC3, indicating that CyaA-promoted nuclear translocation of CRTC3 may account for CyaA-induced IL-10 production. These findings document the complexity of subversive physiological manipulation of myeloid phagocytes by the CyaA toxin, serving in immune evasion of the pertussis agent. PMID- 29176674 TI - Fast and Reliable Differentiation of Eight Trichinella Species Using a High Resolution Melting Assay. AB - High resolution melting analysis (HRMA) is a single-tube method, which can be carried out rapidly as an additional step following real-time quantitative PCR (qPCR). The method enables the differentiation of genetic variation (down to single nucleotide polymorphisms) in amplified DNA fragments without sequencing. HRMA has previously been adopted to determine variability in the amplified genes of a number of organisms. However, only one work to date has focused on pathogenic parasites-nematodes from the genus Trichinella. In this study, we employed a qPCR-HRMA assay specifically targeting two sequential gene fragments cytochrome c oxidase subunit I (COI) and expansion segment V (ESV), in order to differentiate 37 single L1 muscle larvae samples of eight Trichinella species. We show that qPCR-HRMA based on the mitochondrial COI gene allows differentiation between the sequences of PCR products of the same length. This simple, rapid and reliable method can be used to identify at the species level single larvae of eight Trichinella taxa. PMID- 29176675 TI - Strategic inhibition of distractors with visual working memory contents after involuntary attention capture. AB - Previous research has suggested that visual working memory (VWM) contents had a guiding effect on selective attention, and once participants realized that the distractors shared the same information with VWM contents in the search task, they would strategically inhibit the potential distractors with VWM contents. However, previous behavioral studies could not reveal the way how distractors with VWM contents are inhibited strategically. By employing the eye-tracking technique and a dual-task paradigm, we manipulated the probability of memory items occurring as distractors to explore this issue. Consistent with previous behavioral studies, the results showed that the inhibitory effect occurred only in the high-probability condition, while the guiding effect emerged in the low probability condition. More importantly, the eye-movement results indicated that in the high-probability condition, once few (even one) distractors with VWM contents were captured at first, all the remaining distractors with VWM contents would be rejected as a whole. However, in the low-probability condition, attention could be captured by the majority of distractors with VWM contents. These results suggested that the guiding effect of VWM contents on attention is involuntary in the early stage of visual search. After the completion of this involuntary stage, the guiding effect of task-irrelevant VWM contents on attention could be strategically controlled. PMID- 29176677 TI - Organoids model distinct Vitamin E effects at different stages of prostate cancer evolution. AB - Vitamin E increased prostate cancer risk in the Selenium and Vitamin E Cancer Prevention Trial (SELECT) through unknown mechanisms while Selenium showed no efficacy. We determined the effects of the SELECT supplements on benign (primary), premalignant ( RWPE-1) and malignant (LNCaP) prostate epithelial organoids. While the supplements decreased proliferation and induced cell death in cancer organoids, they had no effect on the benign organoids. In contrast, Vitamin E enhanced cell proliferation and survival in the premalignant organoids in a manner that recapitulated the SELECT results. Indeed, while Vitamin E induced a pro-proliferative gene expression signature, Selenium alone or combined with Vitamin E produced an anti-proliferative signature. The premalignant organoids also displayed significant downregulation of glucose transporter and glycolytic gene expression pointing to metabolic alterations. Detached RWPE-1 cells had low ATP levels due to diminished glucose uptake and glycolysis which was rescued by Vitamin E through the activation of fatty acid oxidation (FAO). FAO inhibition abrogated the ATP rescue, diminished survival of the inner matrix detached cells, restoring the normal hollow lumen morphology in Vitamin E treated organoids. Organoid models therefore clarify the paradoxical findings from SELECT and demonstrate that Vitamin E promotes tumorigenesis in the early stages of prostate cancer evolution. PMID- 29176676 TI - Ozone Improves the Aromatic Fingerprint of White Grapes. AB - Ozone, a powerful oxidative stressor, has been recently used in wine industry as sanitizing agent to reduce spoilage microflora on grapes. In this study, we evaluated ozone-induced metabolic and molecular responses during postharvest grape dehydration. Ozone increased the contents of total volatile organic compounds (VOCs), which have a great impact on the organoleptic properties of grapes and wines. Among terpenes, responsible for floral and fruity aroma, linalool, geraniol and nerol were the major aromatic markers of Moscato bianco grapes. They were significantly affected by the long-term ozone treatment, increasing their concentration in the last phases of dehydration (>20% weight loss). At molecular level, our results demonstrated that both postharvest dehydration and ozone exposure induce the biosynthesis of monoterpenes via methylerythritol phosphate (MEP) pathway and of aldehydes from lipoxygenase hydroperoxide lyase (LOX-HPL) pathway. Therefore, transcriptional changes occurred and promoted the over-production of many important volatile compounds for the quality of white grapes. PMID- 29176678 TI - Isochlorogenic acid C prevents enterovirus 71 infection via modulating redox homeostasis of glutathione. AB - Enterovirus 71 (EV71) is a key pathogen of hand, foot and mouth disease (HFMD) in children under 6 years of age. The antiviral potency of antioxidant isochlorogenic acid C (ICAC) extracted from foods was evaluated in cellular and animal models. First, the cytotoxicity of ICAC on Vero cells was investigated. The viral plaques, cytopathic effects and yield induced by EV71 infection were obviously reduced by ICAC, which was consistent with the investigation of VP1 transcripts and protein expression. Moreover, the mortality, weight loss and limb paralysis of mice caused by EV71 challenge were remarkably relieved by ICAC injection, which was achieved through decreases in the viral load and cytokine secretion in the mouse brain. Further biochemical assays showed that ICAC modulated several antioxidant enzymes involved in reduced and oxidized glutathione (GSH and GSSG) homeostasis, including glutathione reductase (GR), glutathione peroxidase (GPX), and glucose-6-phosphate dehydrogenase (G6PD), resulting in restoration of the GSH/GSSG ratio and reactive oxygen species (ROS) level. Finally, the antiviral effects of ICAC were dose-dependently disrupted by BSO, a biosynthesis inhibitor of GSH. This study indicated that ICAC acted as an antioxidant and prevented EV71 infection by modulating the redox homeostasis of glutathione. PMID- 29176679 TI - Volatile organic compounds from Paenibacillus polymyxa KM2501-1 control Meloidogyne incognita by multiple strategies. AB - Plant-parasitic nematodes (PPNs) cause serious crop losses worldwide. In this study, we investigated the nematicidal factors and the modes and mechanisms of action involved in nematode control by Paenibacillus polymyxa KM2501-1. Treatment of the second-stage juveniles (J2) juveniles of PPN Meloidogyne incognita with the biological control agent KM2501-1 resulted in a mortality of 87.66% in vitro and reduced symptoms on tomato by up to 82.61% under greenhouse conditions. We isolated 11 volatile organic compounds (VOCs) from strain KM2501-1, of which 8 had contact nematicidal activity, 6 had fumigant activity, and 5 acted as stable chemotactic agents to M. incognita. The VOCs provided a comprehensive strategy against PPNs that included "honey-trap", fumigant, attractant and repellent modes. Furfural acetone and 2-decanol functioned as "honey-traps" attracting M. incognita and then killing it by contact or fumigation. Two other VOCs, 2 nonanone and 2-decanone, as well as strain KM2501-1 itself, destroyed the integrity of the intestine and pharynx. Collectively our results indicate that VOCs produced by P. polymyxa KM2501-1 act through diverse mechanisms to control M. incognita. Moreover, the novel "honey-trap" mode of VOC-nematode interaction revealed in this study extends our understanding of the strategies exploited by nematicidal biocontrol agents. PMID- 29176680 TI - Identification of novel factors enhancing recombinant protein production in multi copy Komagataella phaffii based on transcriptomic analysis of overexpression effects. AB - The methylotrophic yeast Komagataella phaffii (Pichia pastoris) has been developed into a highly successful system for heterologous protein expression in both academia and industry. However, overexpression of recombinant protein often leads to severe burden on the physiology of K. phaffii and triggers cellular stress. To elucidate the global effect of protein overexpression, we set out to analyze the differential transcriptome of recombinant strains with 12 copies and a single copy of phospholipase A2 gene (PLA 2) from Streptomyces violaceoruber. Through GO, KEGG and heat map analysis of significantly differentially expressed genes, the results indicated that the 12-copy strain suffered heavy cellular stress. The genes involved in protein processing and stress response were significantly upregulated due to the burden of protein folding and secretion, while the genes in ribosome and DNA replication were significantly downregulated possibly contributing to the reduced cell growth rate under protein overexpression stress. Three most upregulated heat shock response genes (CPR6, FES1, and STI1) were co-overexpressed in K. phaffii and proved their positive effect on the secretion of reporter enzymes (PLA2 and prolyl endopeptidase) by increasing the production up to 1.41-fold, providing novel helper factors for rational engineering of K. phaffii. PMID- 29176681 TI - Dynamic disorganization of synaptic NMDA receptors triggered by autoantibodies from psychotic patients. AB - The identification of circulating autoantibodies against neuronal receptors in neuropsychiatric disorders has fostered new conceptual and clinical frameworks. However, detection reliability, putative presence in different diseases and in health have raised questions about potential pathogenic mechanism mediated by autoantibodies. Using a combination of single molecule-based imaging approaches, we here ascertain the presence of circulating autoantibodies against glutamate NMDA receptor (NMDAR-Ab) in about 20% of psychotic patients diagnosed with schizophrenia and very few healthy subjects. NMDAR-Ab from patients and healthy subjects do not compete for binding on native receptor. Strikingly, NMDAR-Ab from patients, but not from healthy subjects, specifically alter the surface dynamics and nanoscale organization of synaptic NMDAR and its anchoring partner the EphrinB2 receptor in heterologous cells, cultured neurons and in mouse brain. Functionally, only patients' NMDAR-Ab prevent long-term potentiation at glutamatergic synapses, while leaving NMDAR-mediated calcium influx intact. We unveil that NMDAR-Ab from psychotic patients alter NMDAR synaptic transmission, supporting a pathogenically relevant role. PMID- 29176682 TI - The Neural Basis of Changing Social Norms through Persuasion. AB - Social norms regulate behavior, and changes in norms have a great impact on society. In most modern societies, norms change through interpersonal communication and persuasive messages found in media. Here, we examined the neural basis of persuasion-induced changes in attitude toward and away from norms using fMRI. We measured brain activity while human participants were exposed to persuasive messages directed toward specific norms. Persuasion directed toward social norms specifically activated a set of brain regions including temporal poles, temporo-parietal junction, and medial prefrontal cortex. Beyond these regions, when successful, persuasion away from an accepted norm specifically recruited the left middle temporal and supramarginal gyri. Furthermore, in combination with data from a separate attitude-rating task, we found that left supramarginal gyrus activity represented participant attitude toward norms and tracked the persuasion-induced attitude changes that were away from agreement. PMID- 29176683 TI - Coronary calcification in adults with Turner syndrome. AB - PurposeAdults with Turner syndrome (TS) have an increased predisposition to ischemic heart disease. The quantitative relationship between coronary atherosclerosis and TS has yet to be established.MethodsA total of 128 females (62 with TS) participated in this prospective study. Coronary computed tomography angiography was performed to measure coronary calcified plaque burden, and prevalent noncalcified plaque burden. Regression analysis was used to study the effects of TS and traditional cardiovascular disease risk factors on coronary plaque burden.ResultsAdults with TS were 63% more likely to have coronary calcifications than controls (odds ratio 1.63, 95% confidence interval: 1.02, 2.61, P = 0.04), with an age cutoff of 51.7 years for a probability of >50% for the presence of coronary calcifications, when compared to 55.7 years in female controls. The average age of TS patients with calcified plaques was significantly lower than that of controls with calcified plaques (51.5 +/- 8.9 years vs. 60.5 +/- 7.0 years, P < 0.001). Age increased the likelihood of coronary calcifications by 13% per year (odds ratio 1.13, confidence interval 95%: 1.07 1.19, P < 0.001).ConclusionThis study demonstrates a higher prevalence and earlier onset of calcified coronary plaques in TS. These findings have important implications for cardiovascular risk assessment and the management of patients with TS. PMID- 29176684 TI - Acupuncture analgesia involves modulation of pain-induced gamma oscillations and cortical network connectivity. AB - Recent studies support the view that cortical sensory, limbic and executive networks and the autonomic nervous system might interact in distinct manners under the influence of acupuncture to modulate pain. We performed a double-blind crossover design study to investigate subjective ratings, EEG and ECG following experimental laser pain under the influence of sham and verum acupuncture in 26 healthy volunteers. We analyzed neuronal oscillations and inter-regional coherence in the gamma band of 128-channel-EEG recordings as well as heart rate variability (HRV) on two experimental days. Pain ratings and pain-induced gamma oscillations together with vagally-mediated power in the high-frequency bandwidth (vmHF) of HRV decreased significantly stronger during verum than sham acupuncture. Gamma oscillations were localized in the prefrontal cortex (PFC), mid-cingulate cortex (MCC), primary somatosensory cortex and insula. Reductions of pain ratings and vmHF-power were significantly correlated with increase of connectivity between the insula and MCC. In contrast, connectivity between left and right PFC and between PFC and insula correlated positively with vmHF-power without a relationship to acupuncture analgesia. Overall, these findings highlight the influence of the insula in integrating activity in limbic-saliency networks with vagally mediated homeostatic control to mediate antinociception under the influence of acupuncture. PMID- 29176685 TI - Orthrozanclus elongata n. sp. and the significance of sclerite-covered taxa for early trochozoan evolution. AB - Orthrozanclus is a shell-bearing, sclerite covered Cambrian organism of uncertain taxonomic affinity, seemingly representing an intermediate between its fellow problematica Wiwaxia and Halkieria. Attempts to group these slug-like taxa into a single 'halwaxiid' clade nevertheless present structural and evolutionary difficulties. Here we report a new species of Orthrozanclus from the early Cambrian Chengjiang Lagerstatte. The scleritome arrangement and constitution in this material corroborates the link between Orthrozanclus and Halkieria, but not with Wiwaxia - and calls into question its purported relationship with molluscs. Instead, the tripartite construction of the halkieriid scleritome finds a more compelling parallel in the camenellan tommotiids, relatives of the brachiopods and phoronids. Such a phylogenetic position would indicate the presence of a scleritome in the common ancestor of the three major trochozoan lineages, Mollusca, Annelida and Brachiozoa. On this view, the absence of fossil Ediacaran sclerites is evidence against any 'Precambrian prelude' to the explosive diversification of these phyla in the Cambrian, c. 540-530 million years ago. PMID- 29176686 TI - The dynamics of intracellular water constrains glycolytic oscillations in Saccharomyces cerevisiae. AB - We explored the dynamic coupling of intracellular water with metabolism in yeast cells. Using the polarity-sensitive probe 6-acetyl-2-dimethylaminonaphthalene (ACDAN), we show that glycolytic oscillations in the yeast S. cerevisiae BY4743 wild-type strain are coupled to the generalized polarization (GP) function of ACDAN, which measures the physical state of intracellular water. We analysed the oscillatory dynamics in wild type and 24 mutant strains with mutations in many different enzymes and proteins. Using fluorescence spectroscopy, we measured the amplitude and frequency of the metabolic oscillations and ACDAN GP in the resting state of all 25 strains. The results showed that there is a lower and an upper threshold of ACDAN GP, beyond which oscillations do not occur. This critical GP range is also phenomenologically linked to the occurrence of oscillations when cells are grown at different temperatures. Furthermore, the link between glycolytic oscillations and the ACDAN GP value also holds when ATP synthesis or the integrity of the cell cytoskeleton is perturbed. Our results represent the first demonstration that the dynamic behaviour of a metabolic process can be regulated by a cell-wide physical property: the dynamic state of intracellular water, which represents an emergent property. PMID- 29176687 TI - Avoidance of seismic survey activities by penguins. AB - Seismic surveys in search for oil or gas under the seabed, produce the most intense man-made ocean noise with known impacts on invertebrates, fish and marine mammals. No evidence to date exists, however, about potential impacts on seabirds. Penguins may be expected to be particularly affected by loud underwater sounds, due to their largely aquatic existence. This study investigated the behavioural response of breeding endangered African Penguins Spheniscus demersus to seismic surveys within 100 km of their colony in South Africa, using a multi year GPS tracking dataset. Penguins showed a strong avoidance of their preferred foraging areas during seismic activities, foraging significantly further from the survey vessel when in operation, while increasing their overall foraging effort. The birds reverted to normal behaviour when the operation ceased, although longer term repercussions on hearing capacities cannot be precluded. The rapid industrialization of the oceans has increased levels of underwater anthropogenic noises globally, a growing concern for a wide range of taxa, now also including seabirds. African penguin numbers have decreased by 70% in the last 10 years, a strong motivation for precautionary management decisions, including the exclusion of seismic exploratory activities within at least 100 km of their breeding colonies. PMID- 29176688 TI - Elevated moisture stimulates carbon loss from mineral soils by releasing protected organic matter. AB - Moisture response functions for soil microbial carbon (C) mineralization remain a critical uncertainty for predicting ecosystem-climate feedbacks. Theory and models posit that C mineralization declines under elevated moisture and associated anaerobic conditions, leading to soil C accumulation. Yet, iron (Fe) reduction potentially releases protected C, providing an under-appreciated mechanism for C destabilization under elevated moisture. Here we incubate Mollisols from ecosystems under C3/C4 plant rotations at moisture levels at and above field capacity over 5 months. Increased moisture and anaerobiosis initially suppress soil C mineralization, consistent with theory. However, after 25 days, elevated moisture stimulates cumulative gaseous C-loss as CO2 and CH4 to >150% of the control. Stable C isotopes show that mineralization of older C3-derived C released following Fe reduction dominates C losses. Counter to theory, elevated moisture may significantly accelerate C losses from mineral soils over weeks to months-a critical mechanistic deficiency of current Earth system models.

AB - Fungal endophytes isolated from mountain-cultivated ginseng (MCG, Panax ginseng Meyer) were explored for their diversity and biocontrol activity against ginseng pathogens (Alternaria panax, Botrytis cinerea, Cylindrocarpon destructans, Pythium sp. and Rhizoctonia solani). A total of 1,300 isolates were isolated from three tissues (root, stem and leaf) from MCGs grown in 24 different geographic locations in Korea. In total, 129 different fungal isolates were authenticated by molecular identification based on internal transcribed spacer (ITS) sequences. The fungal endophytes belonged to Ascomycota (81.7%), Basidiomycota (7.08%), Zygomycota (10%) and Unknown (1.15%), with 59 genera. Analysis of diversity indices across sampling sites suggested species abundance as a function of geographical and environmental factors of the locations. Shannon diversity index and richness in the different tissues revealed that root tissues are colonized more than stem and leaf tissues, and also certain fungal endophytes are tissue specific. Assessment of the ethyl acetate extracts from 129 fungal isolates for their biocontrol activity against 5 ginseng pathogens revealed that Trichoderma polysporum produces the antimcriobial metabolite against all the pathogens. This result indicates the promise of its potential usage as a biocontrol agent.

AB - Thrombocytopenia is a major side effect of a new class of anticancer agents that target histone deacetylase (HDAC). Their mechanism is poorly understood. Here, we show that HDAC6 inhibition and genetic knockdown lead to a strong decrease in human proplatelet formation (PPF). Unexpectedly, HDAC6 inhibition-induced tubulin hyperacetylation has no effect on PPF. The PPF decrease induced by HDAC6 inhibition is related to cortactin (CTTN) hyperacetylation associated with actin disorganization inducing important changes in the distribution of megakaryocyte (MK) organelles. CTTN silencing in human MKs phenocopies HDAC6 inactivation and knockdown leads to a strong PPF defect. This is rescued by forced expression of a deacetylated CTTN mimetic. Unexpectedly, unlike human-derived MKs, HDAC6 and CTTN are shown to be dispensable for mouse PPF in vitro and platelet production in vivo. Our results highlight an unexpected function of HDAC6-CTTN axis as a positive regulator of human but not mouse MK maturation. PMID- 29176691 TI - Midkine derived from cancer-associated fibroblasts promotes cisplatin-resistance via up-regulation of the expression of lncRNA ANRIL in tumour cells. AB - Midkine (MK) is a heparin-binding growth factor that promotes carcinogenesis and chemoresistance. The tumour microenvironment (TME) can affect chemotherapy sensitivity. However, the role of stromal-derived MK, especially in cancer associated fibroblasts (CAFs), is unclear. Here, we confirmed that MK decreased cisplatin-induced cell death in oral squamous cell carcinoma (OSCC) cells, ovarian cancer cells and lung cancer cells. We also isolated primary CAFs (n = 3) from OSCC patients and found that CAFs secreted increased levels of MK, which abrogated cisplatin-induced cell death. Moreover, MK increased the expression of lncRNA ANRIL in the tumour cells. Normal tissues, matched tumour-adjacent tissues and OSCC tissues were analysed (n = 60) and showed that lncRNA ANRIL was indeed overexpressed during carcinogenesis and correlated with both high TNM stage and lymph node metastasis (LNM). Furthermore, lncRNA ANRIL knockdown in tumour cells inhibited proliferation, induced apoptosis and increased cisplatin cytotoxicity of the tumour cells via impairment of the drug transporters MRP1 and ABCC2, which could be restored by treatment with human MK in a caspase-3/BCL-2-dependent manner. In conclusion, we firstly describe that CAFs in the TME contribute to the high level of MK in tumours and that CAF-derived MK can promote cisplatin resistance via the elevated expression of lncRNA ANRIL.

AB - The insecticidal Vip3 proteins from Bacillus thuringiensis (Bt), along with the classical Bt Cry proteins, are currently used in Bt-crops to control insect pests, since they do not share the same mode of action. Here we characterized the response of Spodoptera exigua larvae after Vip3 challenge. The expression profile of 47 genes was analyzed in larvae challenged with three concentrations of Vip3Ca. Results showed that the up-regulated genes were mainly involved in immune response, whereas the down-regulated genes were mainly involved in the digestion process. Other mechanisms of cellular response to the damage such as apoptosis were analyzed. For this analysis, sections from the midguts were examined by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining. The nuclei of the midgut epithelial cells were stained at the highest concentration of the Vip3Ca protein and at lower concentrations of Vip3Aa in agreement with the different potency of the two proteins. In addition, apoptosis was also examined by the analysis of the expression of five caspase genes. The present study shows that exposure of S. exigua larvae to sublethal concentrations of Vip3 proteins activates different insect response pathways which trigger the regulation of some genes, APN shedding, and apoptotic cell death.

AB - The presence of splicing sequence variants in genes responsible for sex development in humans may compromise correct biosynthesis of proteins involved in the normal development of gonads and external genitalia. In a cohort of Brazilian patients, we identified mutations in HSD17B3 and SRD5A2 which are both required for human sexual differentiation. A number of these mutations occurred within regions potentially critical for splicing regulation. Minigenes were used to validate the functional effect of mutations in both genes. We evaluated the c.277 + 2 T > G mutation in HSD17B3, and the c.544 G > A, c.548-44 T > G and c.278delG mutations in SRD5A2. We demonstrated that these mutations altered the splicing pattern of these genes. In a genomic era these results illustrate, and remind us, that sequence variants within exon-intron boundaries, which are primarily identified for diagnostic purposes and have unknown pathogenicity, need to be assessed with regards to their impact not only on protein expression, but also on mRNA splicing.

AB - While patient selection and clinical management have reduced high-dose IL-2 (HDIL2) immunotherapy toxicities, the immune mechanisms that underlie HDIL2 induced morbidity remain unclear. Here we show that dose-dependent morbidity and mortality of IL-2 immunotherapy can be modeled in human immune system (HIS) mice. Depletion of human T cell subsets during the HDIL2 treatment reduces toxicity, pointing to the central function of T cells. Preferential expansion of effector T cells secondary to defective suppressive capacity of regulatory T (Treg) cells after HDIL2 therapy further underscores the importance of Treg in the maintenance of immune tolerance. IL-2 toxicity is induced by selective depletion or inhibition of Treg after LDIL2 therapy, and is ameliorated in HDIL2-treated HIS mice receiving the PIM-1 kinase inhibitor, Kaempferol. Modeling IL-2 pathophysiology in HIS mice offers a means to understand the functions of effector and regulatory T cells in immune-mediated toxicities associated with cancer immunotherapy.

AB - Squamous cell carcinomas of the head and neck (SCCHN) affect anatomical sites including the oral cavity, nasal cavity, pharynx, and larynx. Laryngeal cancers are characterized by high recurrence and poor overall survival, and currently lack robust molecular prognostic biomarkers for treatment stratification. Using an algorithm for integrative clustering that simultaneously assesses gene expression, somatic mutation, copy number variation, and methylation, we for the first time identify laryngeal cancer subtypes with distinct prognostic outcomes, and differing from the non-prognostic laryngeal subclasses reported by The Cancer Genome Atlas (TCGA). Although most common laryngeal gene mutations are found in both subclasses, better prognosis is strongly associated with damaging mutations of the methyltransferases NSD1 and NSD2, with findings confirmed in an independent validation cohort consisting of 63 laryngeal cancer patients. Intriguingly, NSD1/2 mutations are not prognostic for nonlaryngeal SCCHN. These results provide an immediately useful clinical metric for patient stratification and prognostication. PMID- 29176704 TI - Gas hydrate saturations estimated from pore-and fracture-filling gas hydrate reservoirs in the Qilian Mountain permafrost, China. AB - Accurate calculation of gas hydrate saturation is an important aspect of gas hydrate resource evaluation. The effective medium theory (EMT model), the velocity model based on two-phase medium theory (TPT model), and the two component laminated media model (TCLM model), are adopted to investigate the characteristics of acoustic velocity and gas hydrate saturation of pore- and fracture-filling reservoirs in the Qilian Mountain permafrost, China. The compressional wave (P-wave) velocity simulated by the EMT model is more consistent with actual log data than the TPT model in the pore-filling reservoir. The range of the gas hydrate saturation of the typical pore-filling reservoir in hole DKXX-13 is 13.0~85.0%, and the average value of the gas hydrate saturation is 61.9%, which is in accordance with the results by the standard Archie equation and actual core test. The P-wave phase velocity simulated by the TCLM model can be transformed directly into the P-wave transverse velocity in a fracture-filling reservoir. The range of the gas hydrate saturation of the typical fracture filling reservoir in hole DKXX-19 is 14.1~89.9%, and the average value of the gas hydrate saturation is 69.4%, which is in accordance with actual core test results. PMID- 29176705 TI - Disrupted Brain Network in Children with Autism Spectrum Disorder. AB - Alterations in brain connectivity have been extensively reported in autism spectrum disorder (ASD), while their effects on the topology of brain network are still unclear. This study investigated whether and how the brain networks in children with ASD were abnormally organized with resting state EEG. Temporal synchronization analysis was first applied to capture the aberrant brain connectivity. Then brain network topology was characterized by three graph analysis methods including the commonly-used weighted and binary graph, as well as minimum spanning tree (MST). Whole brain connectivity in ASD group was found to be significantly reduced in theta and alpha band compared to typically development children (TD). Weighted graph found significantly decreased path length together with marginally significantly decreased clustering coefficient in ASD in alpha band, indicating a loss of small-world architecture to a random network. Such abnormal network topology was also demonstrated in the binary graph. In MST analysis, children with ASD showed a significant lower leaf fractions with a decrease trend of tree hierarchy in the alpha band, suggesting a shift towards line-like decentralized organization in ASD. The altered brain network may offer an insight into the underlying pathology of ASD and possibly serve as a biomarker that may aid in diagnosis of ASD. PMID- 29176706 TI - Simultaneous fabrication of line and dot dual nanopatterns using miktoarm block copolymer with photocleavable linker. AB - Block copolymers with various nanodomains, such as spheres, cylinders, and lamellae, have received attention for their applicability to nanolithography. However, those microdomains are determined by the volume fraction of one block. Meanwhile, nanopatterns with multiple shapes are required for the next-generation nanolithography. Although various methods have been reported to achieve dual nanopatterns, all the methods need sophisticated processes using E-beam. Here, we synthesized a miktoarm block copolymer capable of cleavage of one block by ultraviolet. Original cylindrical nanodomains of synthesized block copolymer were successfully transformed to lamellar nanodomains due to the change of molecular architecture by ultraviolet. We fabricated dual nanopatterns consisting of dots and lines at desired regions on a single substrate. We also prepared dual nanopatterns utilizing another phase transformation from spheres to cylinders in a block copolymer with higher interaction parameter. Since our concept has versatility to any block copolymer, it could be employed as next-generation nanolithography. PMID- 29176707 TI - Neolithic cultivation of water chestnuts (Trapa L.) at Tianluoshan (7000-6300 cal BP), Zhejiang Province, China. AB - Water chestnuts (Trapa) are frequently recovered at Neolithic sites along the Lower Yangtze River Valley and have been important components of the diets of prehistoric people. However, little systematic research has been conducted to determine their cultural and dietary importance. Excavations at the Tianluoshan site produced large quantities of well-preserved specimens, which provide an excellent collection for studying morphological changes with time. Using modern wild and domesticated water chestnuts (n = 447) as a reference, we find Neolithic samples (n = 481) at Tianluoshan are similar in shape but smaller in size compared to the domesticated species Trapa bispinosa. In particular, the Tianluoshan water chestnuts have bigger seeds than the wild species Trapa incisa. Further, water chestnuts diachronically increased in size at the Tianluoshan site with significant differences (one-way, ANOVA) observed for length (p = 7.85E-08), height (p = 3.19E-06), thickness (p = 1.2E-13), top diameter (p = 5.04E-08) and bottom diameter (p = 1.75E-05) between layers 7 (6700-6500 cal BP) and 6 (6500 6300 cal BP). These results suggest that water chestnuts were actively selected based on size (big), shape (full fruit, two round horns, wide base, etc.) and were an important non-cereal crop to the agricultural practices at the Tianluoshan site. PMID- 29176708 TI - The Abeta oligomer eliminating D-enantiomeric peptide RD2 improves cognition without changing plaque pathology. AB - While amyloid-beta protein (Abeta) aggregation into insoluble plaques is one of the pathological hallmarks of Alzheimer's disease (AD), soluble oligomeric Abeta has been hypothesized to be responsible for synapse damage, neurodegeneration, learning, and memory deficits in AD. Here, we investigate the in vitro and in vivo efficacy of the D-enantiomeric peptide RD2, a rationally designed derivative of the previously described lead compound D3, which has been developed to efficiently eliminate toxic Abeta42 oligomers as a promising treatment strategy for AD. Besides the detailed in vitro characterization of RD2, we also report the results of a treatment study of APP/PS1 mice with RD2. After 28 days of treatment we observed enhancement of cognition and learning behaviour. Analysis on brain plaque load did not reveal significant changes, but a significant reduction of insoluble Abeta42. Our findings demonstrate that RD2 was significantly more efficient in Abeta oligomer elimination in vitro compared to D3. Enhanced cognition without reduction of plaque pathology in parallel suggests that synaptic malfunction due to Abeta oligomers rather than plaque pathology is decisive for disease development and progression. Thus, Abeta oligomer elimination by RD2 treatment may be also beneficial for AD patients. PMID- 29176709 TI - Can Niche Modeling and Geometric Morphometrics Document Competitive Exclusion in a Pair of Subterranean Rodents (Genus Ctenomys) with Tiny Parapatric Distributions? AB - Species with similar ecological requirements coexisting in the same geographic region are prone to competitively exclude each other. Alternatively, they may coexist if character displacement acts to change the niche requirements of one or both species. We used two methodological approaches (ecological niche modeling [ENM] and geometric morphometrics) to test two hypotheses: given their behavioral, morphological, and ecological similarities, one species competitively excludes the other; and, character displacement enables their coexistence at two sites in which the species are known to occur in sympatry. The results from the ENM-based approach did not provide evidence for competitive exclusion; however, the morphometric analyses documented displacement in size of C. minutus. This result, suggests that C. minutus might exclude C. flamarioni from areas with softer soils and higher food availability. We stress the importance of using multiple methodological approaches when testing prediction of competitive exclusion. However, both methods had limited explanatory power given that the focal species possess truly peculiar distributions, being largely parapatric and restricted to narrow, small geographic areas with a strange distribution and there is a need to search for additional methods. We discuss the idiosyncrasy of the ENM-based approach when applied to organisms with subterranean habits. PMID- 29176710 TI - Functional analysis of photosynthetic pigment binding complexes in the green alga Haematococcus pluvialis reveals distribution of astaxanthin in Photosystems. AB - Astaxanthin is a ketocarotenoid produced by photosynthetic microalgae. It is a pigment of high industrial interest in acquaculture, cosmetics, and nutraceutics due to its strong antioxidant power. Haematococcus pluvialis, a fresh-water microalga, accumulates high levels of astaxanthin upon oxidative stress, reaching values up to 5% per dry weight. H. pluvialis accumulates astaxanthin in oil droplets in the cytoplasm, while the chloroplast volume is reduced. In this work, we investigate the biochemical and spectroscopic properties of the H. pluvialis pigment binding complexes responsible for light harvesting and energy conversion. Our findings demonstrate that the main features of chlorophyll and carotenoid binding complexes previously reported for higher plants or Chlamydomonas reinhardtii are preserved under control conditions. Transition to astaxanthin rich cysts however leads to destabilization of the Photosystems. Surprisingly, astaxanthin was found to be bound to both Photosystem I and II, partially substituting beta-carotene, and thus demonstrating possible astaxanthin biosynthesis in the plastids or transport from the cytoplasm to the chloroplast. Astaxanthin binding to Photosystems does not however improve their photoprotection, but rather reduces the efficiency of excitation energy transfer to the reaction centers. We thus propose that astaxanthin binding partially destabilizes Photosystem I and II. PMID- 29176711 TI - Exploration of Protein Unfolding by Modelling Calorimetry Data from Reheating. AB - Studies of protein unfolding mechanisms are critical for understanding protein functions inside cells, de novo protein design as well as defining the role of protein misfolding in neurodegenerative disorders. Calorimetry has proven indispensable in this regard for recording full energetic profiles of protein unfolding and permitting data fitting based on unfolding pathway models. While both kinetic and thermodynamic protein stability are analysed by varying scan rates and reheating, the latter is rarely used in curve-fitting, leading to a significant loss of information from experiments. To extract this information, we propose fitting both first and second scans simultaneously. Four most common single-peak transition models are considered: (i) fully reversible, (ii) fully irreversible, (iii) partially reversible transitions, and (iv) general three state models. The method is validated using calorimetry data for chicken egg lysozyme, mutated Protein A, three wild-types of haloalkane dehalogenases, and a mutant stabilized by protein engineering. We show that modelling of reheating increases the precision of determination of unfolding mechanisms, free energies, temperatures, and heat capacity differences. Moreover, this modelling indicates whether alternative refolding pathways might occur upon cooling. The Matlab-based data fitting software tool and its user guide are provided as a supplement. PMID- 29176712 TI - Variation in iodine food composition data has a major impact on estimates of iodine intake in young children. AB - BACKGROUND/OBJECTIVES: The reliability of an estimate of iodine intake is largely dependent on the quality of the food composition data. We aimed to assess the impact of variations in food composition data for iodine and season on the estimates of iodine intake in young children. SUBJECTS/METHODS: Cross-sectional dietary intake study of Irish 2-year-olds participating in the Cork BASELINE Birth Cohort Study (n=468; 30% of the cohort at the 2-year follow-up) were used to assess the impact of variation in iodine food composition data on estimates of iodine intake, dietary adequacy and risk of exceeding the tolerable upper intake level (UL). RESULTS: Mean (SD) iodine intakes calculated using UK (147 (71)) and Irish (177 (93)) food composition data were significantly different (P < 0.001) (mean difference (95% confidence interval) = 30 (26-33) ug/day) and largely adequate (7-14% below the estimated average requirement). Intakes at the 95th percentile were 138% and 173% of the UL using UK and Irish food composition data, respectively, of which milk accounted for 106% and 150% of the UL. This translated into 22% and 35% of toddlers exceeding the UL, using UK and Irish composition data, respectively. The mean (SD) daily intake of cow's milk among the 91% of consumers was 309 (208) ml. Intakes of cow's milk at the 75th and 95th percentiles were 452 and 706 ml, respectively. Using Irish composition data for iodine in cows' milk, a daily intake of 450 ml could result in a toddler exceeding the UL from milk alone. CONCLUSIONS: Variability in food composition has a large impact on assessments of iodine intake, particularly among young children for whom milk contributes a large proportion of their daily nutrient intake. Although this is unlikely to result in long-term adverse effects, our study highlights the need for development of valid biomarkers of individual iodine status. PMID- 29176713 TI - Rapid resetting of human peripheral clocks by phototherapy during simulated night shift work. AB - A majority of night shift workers have their circadian rhythms misaligned to their atypical schedule. While bright light exposure at night is known to reset the human central circadian clock, the behavior of peripheral clocks under conditions of shift work is more elusive. The aim of the present study was to quantify the resetting effects of bright light exposure on both central (plasma cortisol and melatonin) and peripheral clocks markers (clock gene expression in peripheral blood mononuclear cells, PBMCs) in subjects living at night. Eighteen healthy subjects were enrolled to either a control (dim light) or a bright light group. Blood was sampled at baseline and on the 4th day of simulated night shift. In response to a night-oriented schedule, the phase of PER1 and BMAL1 rhythms in PBMCs was delayed by ~2.5-3 h (P < 0.05), while no shift was observed for the other clock genes and the central markers. Three cycles of 8-h bright light induced significant phase delays (P < 0.05) of ~7-9 h for central and peripheral markers, except BMAL1 (advanced by +5h29; P < 0.05). Here, we demonstrate in humans a lack of peripheral clock adaptation under a night-oriented schedule and a rapid resetting effect of nocturnal bright light exposure on peripheral clocks. PMID- 29176715 TI - Inhalation Exposure to PM2.5 Counteracts Hepatic Steatosis in Mice Fed High-fat Diet by Stimulating Hepatic Autophagy. AB - Air pollution is associated with the increased risk of metabolic syndrome. In this study, we performed inhalation exposure of mice fed normal chow or a high fat diet to airborne fine particulate matters (PM2.5), and then investigated the complex effects and mechanisms of inhalation exposure to PM2.5 on hepatic steatosis, a precursor or manifestation of metabolic syndrome. Our studies demonstrated that inhalation exposure of mice fed normal chow to concentrated ambient PM2.5 repressed hepatic transcriptional regulators involved in fatty acid oxidation and lipolysis, and thus promoted hepatic steatosis. However, PM2.5 exposure relieved hepatic steatosis in high-fat diet-induced obese mice. Further investigation revealed that inhalation exposure to PM2.5 induced hepatic autophagy in mouse livers in a manner depending on the MyD88-mediated inflammatory pathway. The counteractive effect of PM2.5 exposure on high-fat diet induced hepatic steatosis was mediated through PM2.5-induced hepatic autophagy. The findings from this study not only defined the effects and mechanisms of PM2.5 exposure in metabolic disorders, but also revealed the pleotrophic acts of an environmental stressor in a complex stress system relevant to public health. PMID- 29176714 TI - Analyses of gut microbiota and plasma bile acids enable stratification of patients for antidiabetic treatment. AB - Antidiabetic medication may modulate the gut microbiota and thereby alter plasma and faecal bile acid (BA) composition, which may improve metabolic health. Here we show that treatment with Acarbose, but not Glipizide, increases the ratio between primary BAs and secondary BAs and plasma levels of unconjugated BAs in treatment-naive type 2 diabetes (T2D) patients, which may beneficially affect metabolism. Acarbose increases the relative abundances of Lactobacillus and Bifidobacterium in the gut microbiota and depletes Bacteroides, thereby changing the relative abundance of microbial genes involved in BA metabolism. Treatment outcomes of Acarbose are dependent on gut microbiota compositions prior to treatment. Compared to patients with a gut microbiota dominated by Prevotella, those with a high abundance of Bacteroides exhibit more changes in plasma BAs and greater improvement in metabolic parameters after Acarbose treatment. Our work highlights the potential for stratification of T2D patients based on their gut microbiota prior to treatment. PMID- 29176716 TI - A rapidly-reversible absorptive and emissive vapochromic Pt(II) pincer-based chemical sensor. AB - Selective, robust and cost-effective chemical sensors for detecting small volatile-organic compounds (VOCs) have widespread applications in industry, healthcare and environmental monitoring. Here we design a Pt(II) pincer-type material with selective absorptive and emissive responses to methanol and water. The yellow anhydrous form converts reversibly on a subsecond timescale to a red hydrate in the presence of parts-per-thousand levels of atmospheric water vapour. Exposure to methanol induces a similarly-rapid and reversible colour change to a blue methanol solvate. Stable smart coatings on glass demonstrate robust switching over 104 cycles, and flexible microporous polymer membranes incorporating microcrystals of the complex show identical vapochromic behaviour. The rapid vapochromic response can be rationalised from the crystal structure, and in combination with quantum-chemical modelling, we provide a complete microscopic picture of the switching mechanism. We discuss how this multiscale design approach can be used to obtain new compounds with tailored VOC selectivity and spectral responses. PMID- 29176717 TI - High miR-205 expression in normal epithelium is associated with biochemical failure - an argument for epithelial crosstalk in prostate cancer? AB - Due to insufficient prognostic tools, failure to predict aggressive prostate cancer (PC) has left patient selection for radical treatment an unsolved challenge. This has resulted in overtreatment with radical therapy. Better prognostic tools are urgently warranted. MicroRNAs (miRs) have emerged as important regulators of cellular pathways, resulting in altered gene expressions. miR-205 has previously been observed downregulated in PC, acting as tumor suppressor. Herein, the expression of miR-205 in prostate tissue was examined in a large, well-described cohort of 535 Norwegian prostatectomy patients. Using in situ hybridization, miR-205 expression was semiquantatively measured in normal and tumor tissues from radical prostatectomy specimens. Associations with clinicopathological data and PC relapse were calculated. Expression of miR-205 was lower in tumor epithelium compared to normal epithelium. No association was observed between miR-205 expression in primary tumor epithelium and cancer relapse. In contrast, high expression of miR-205 in normal epithelium was independently associated with biochemical relapse (HR = 1.64, p = 0.003). A prognostic importance of miR-205 expression was only found in the normal epithelium, raising the hypothesis of epithelial crosstalk between normal and tumor epithelium in PC. This finding supports the proposed novel hypothesis of an anti-cancerogenous function of normal epithelium in tumor tissue. PMID- 29176718 TI - Sorption Hysteresis of Light Hydrocarbons and Carbon Dioxide in Shale and Kerogen. AB - We present adsorption and desorption isotherms of methane, ethane, propane, n butane and iso-butane as well as carbon dioxide for two shales and isolated kerogens determined by a gravimetric method. The sorption measurements of two shales were performed at three different temperatures, 308.15, 323.15, and 338.15 K. For the isolated kerogens, the measurements were conducted at 338.15 K. Methane and ethane sorption isotherms were measured to 35 bar. Carbon dioxide sorption isotherms were studied to 30 bar. Due to the low vapor pressure at room temperature, the sorption isotherms of propane, n-butane and iso-butane were measured to 8, 2, and 2 bar, respectively. The adsorptions of propane, n-butane, and iso-butane were much higher than methane at the highest pressures where the measurements were conducted. The adsorption of n-butane was 10 times higher than methane by mole at 2 bar, followed by iso-butane and propane. Our data show significant adsorption hysteresis in ethane, propane, n-butane and iso-butane. The most pronounced hysteresis was found in n-butane and iso-butane. Significant hysteresis is attributed to the reversible structural changes of kerogens. Dissolution of adsorbates into organic matter may also affect the hysteresis. This is the first report of propane and butane sorption isotherms in shales. PMID- 29176719 TI - Structural Mechanism of the Oxygenase JMJD6 Recognition by the Extraterminal (ET) Domain of BRD4. AB - Jumonji domain-containing protein 6 (JMJD6) is a member of the Jumonji C family of Fe(II) and 2-oxoglutarate (2OG) dependent oxygenases. It possesses unique bi functional oxygenase activities, acting as both an arginine demethylase and a lysyl-hydroxylase. JMJD6 has been reported to be over-expressed in oral, breast, lung, and colon cancers and plays important roles in regulation of transcription through interactions with transcription regulator BRD4, histones, U2AF65, Luc7L3, and SRSF11. Here, we report a structural mechanism revealed by NMR of JMJD6 recognition by the extraterminal (ET) domain of BRD4 in that a JMJD6 peptide (Lys84-Asn96) adapts an alpha-helix when bound to the ET domain. This intermolecular recognition is established through JMJD6 interactions with the conserved hydrophobic core of the ET domain, and reinforced by electrostatic interactions of JMJD6 with residues in the inter-helical alpha1-alpha2 loop of the ET domain. Notably, this mode of ligand recognition is different from that of ET domain recognition of NSD3, LANA of herpesvirus, and integrase of MLV, which involves formation of an intermolecular amphipathic two- or three- strand antiparallel beta sheet. Furthermore, we demonstrate that the association between the BRD4 ET domain and JMJD6 likely requires a protein conformational change induced by single-stranded RNA binding. PMID- 29176720 TI - Invasive plants as potential food resource for native pollinators: A case study with two invasive species and a generalist bumble bee. AB - It is now well established that invasive plants may induce drifts in the quantity and/or quality of floral resources. They are then often pointed out as a potential driver of bee decline. However, their impact on bee population remains quite unclear and still controversial, as bee responses are highly variable among species. Here, we compared the amino acid composition of pollen from three native and two invasive plant species included in diets of common pollinators in NW Europe. Moreover, the nutritional intake (i.e., pollen and amino acid intakes) of Bombus terrestris colonies and the pollen foraging behaviour of workers (i.e., visiting rate, number of foraging trips, weight of pollen loads) were considered. We found significant differences in pollen nutrients among the studied species according to the plant invasive behaviour. We also found significant differences in pollen foraging behaviour according to the plant species, from few to several foraging trips carrying small or large pollen loads. Such behavioural differences directly impacted the pollen intake but depended more likely on plant morphology rather than on plant invasive behaviour. These results suggest that common generalist bumble bees might not always suffer from plant invasions, depending on their behavioural plasticity and nutritional requirements. PMID- 29176721 TI - Interocular Symmetry of Vascular Density and Association with Central Macular Thickness of Healthy Adults by Optical Coherence Tomography Angiography. AB - In order to analyze the interocular correlation of vascular density, foveal avascular zone (FAZ) size, central macular thickness (CMT), and to investigate the relationship between vascular density and CMT in normal eyes, retinal vascular density in superficial capillary plexus (SCP), deep capillary plexus (DCP) and choriocapillaris (CC) networks, FAZ size, and CMT were visualized by optical coherence tomography (OCT) angiography. A total of 174 eyes of 87 normal Chinese subjects were enrolled in the study. The results showed that FAZ and CMT measurements are not statistically significant between right and left eyes, but right eyes had higher vascular density in superficial, deep retinal capillary and choriocapillaris networks, which might be related with dominant eyes. Spearman correlation test revealed a high correlation between right and left eyes for FAZ and CMT measurements (r = 0.934; r = 0.935), and a moderate correlation for SCP, DCP and CC density (r = 0.402; r = 0.666; r = 0.417). The analysis showed greater vascular density with smaller FAZ size, and a high negative relationship between FAZ and CMT, which indicates a positive correlation between retinal blood supply and retinal thickness.

AB - The study of past sea levels relies largely on the interpretation of sea-level indicators. Palaeo tidal notches are considered as one of the most precise sea level indicators as their formation is closely tied to the local tidal range. We present geometric measurements of modern and palaeo (Marine Isotope Stage (MIS) 5e) tidal notches on Bonaire (southern Caribbean Sea) and results from two tidal simulations, using the present-day bathymetry and a palaeo-bathymetry. We use these two tools to investigate changes in the tidal range since MIS 5e. Our models show that the tidal range changes most significantly in shallow areas, whereas both, notch geometry and models results, suggest that steeper continental shelves, such as the ones bordering the island of Bonaire, are less affected to changes in tidal range in conditions of MIS 5e sea levels. We use our data and results to discuss the importance of considering changes in tidal range while reconstructing MIS 5e sea level histories, and we remark that it is possible to use hydrodynamic modelling and notch geometry as first-order proxies to assess whether, in a particular area, tidal range might have been different in MIS 5e with respect to today.

AB - Molecular mechanisms of Na+, Cl-, and Ca2+ regulation in ionocytes of fish have been well investigated. However, the regulatory mechanism of K+ in fishes has been largely unknown. In this study, we investigated the mechanism of K+ regulation in medaka larvae acclimated to fresh water. Using a scanning ion selective electrode technique (SIET) to measure the K+ fluxes at skin cells, significant K+ effluxes were found at ionocytes; in contrast, significant K+ influxes were found at the boundaries between keratinocytes. High K+ water (HK) acclimation induced the K+ effluxes at ionocytes and suppressed the K+ influxes at keratinocytes. The K+ effluxes of ionocytes were suppressed by VU591, bumetanide and ouabain. The K+ influxes of keratinocytes were suppressed by TAP. In situ hybridization analysis showed that mRNA of ROMKa was expressed by ionocytes in the skin and gills of medaka larvae. Quantitative PCR showed that mRNA levels of ROMKa and NKCC1a in gills of adult medaka were upregulated after HK acclimation. This study suggests that medaka obtain K+ through a paracellular pathway between keratinocytes and extrude K+ through ionocytes; apical ROMKa and basolateral NKCC1a are involved in the K+ secretion by ionocytes.

AB - Transformations of extracellular matrix (ECM) accompany pathological tissue changes, yet how cell-ECM crosstalk drives these processes remains unknown as adequate tools to probe forces or mechanical strains in tissues are lacking. Here, we introduce a new nanoprobe to assess the mechanical strain of fibronectin (Fn) fibers in tissue, based on the bacterial Fn-binding peptide FnBPA5. FnBPA5 exhibits nM binding affinity to relaxed, but not stretched Fn fibers and is shown to exhibit strain-sensitive ECM binding in cell culture in a comparison with an established Fn-FRET probe. Staining of tumor tissue cryosections shows large regions of relaxed Fn fibers and injection of radiolabeled 111In-FnBPA5 in a prostate cancer mouse model reveals specific accumulation of 111In-FnBPA5 in tumor with prolonged retention compared to other organs. The herein presented approach enables to investigate how Fn fiber strain at the tissue level impacts cell signaling and pathological progression in different diseases. PMID- 29176725 TI - Distinct neural substrates of visuospatial and verbal-analytic reasoning as assessed by Raven's Advanced Progressive Matrices. AB - Recent studies revealed spontaneous neural activity to be associated with fluid intelligence (gF) which is commonly assessed by Raven's Advanced Progressive Matrices, and embeds two types of reasoning: visuospatial and verbal-analytic reasoning. With resting-state fMRI data, using global brain connectivity (GBC) analysis which averages functional connectivity of a voxel in relation to all other voxels in the brain, distinct neural correlates of these two reasoning types were found. For visuospatial reasoning, negative correlations were observed in both the primary visual cortex (PVC) and the precuneus, and positive correlations were observed in the temporal lobe. For verbal-analytic reasoning, negative correlations were observed in the right inferior frontal gyrus (rIFG), dorsal anterior cingulate cortex and temporoparietal junction, and positive correlations were observed in the angular gyrus. Furthermore, an interaction between GBC value and type of reasoning was found in the PVC, rIFG and the temporal lobe. These findings suggest that visuospatial reasoning benefits more from elaborate perception to stimulus features, whereas verbal-analytic reasoning benefits more from feature integration and hypothesis testing. In sum, the present study offers, for different types of reasoning in gF, first empirical evidence of separate neural substrates in the resting brain.

PMID- 29176727 TI - Prognostic value of thyroid hormones in acute ischemic stroke - a meta analysis. AB - Previous studies on the association between thyroid hormones and prognosis of acute ischemic stroke (AIS) reported conflicting results. We conducted a meta analysis to assess the prognostic value of thyroid hormones in AIS. The PubMed, EMBASE, and Cochrane library databases were searched through May 12, 2017 to identify eligible studies on this subject. Out of 2,181 studies retrieved, 11 studies were finally included with a total number of 3,936 acute stroke patients for analysis. Odds ratio (OR) for predicting poor outcome or standardized mean difference (SMD) of thyroid hormone levels with 95% confidence intervals (95% CI) obtained from the studies were pooled using Review Manager 5.3. From the results, in AIS, patients with a poor outcome had lower levels of triiodothyronine (T3) and higher thyroxine (T4). Pooled OR confirmed the same association. Our study provides statistical evidence supporting the utility of thyroid hormone levels in prognosis of acute stroke. PMID- 29176728 TI - Similarities between acylcarnitine profiles in large for gestational age newborns and obesity. AB - Large for gestational age (LGA) newborns have an increased risk of obesity, insulin resistance, and metabolic syndrome. Acylcarnitine profiles in obese children and adults are characterized by increased levels of C3, C5, and certain medium-chain (C12) and long-chain (C14:1 and C16) acylcarnitines. C2 is also increased in insulin-resistant states. In this 1-year observational study of 2514 newborns (246 LGA newborns, 250 small for gestational age (GA) newborns, and 2018 appropriate for GA newborns), we analyzed and compared postnatal acylcarnitine profiles in LGA newborns with profiles described for obese individuals. Acylcarnitine analysis was performed by tandem mass spectrometry on dried-blood spots collected on day 3 of life. LGA newborns had higher levels of total short chain acylcarnitines (p < 0.001), C2 (p < 0.01) and C3 (p < 0.001) acylcarnitines, and all C12, C14, and C16 acylcarnitines except C12:1. They also had a higher tendency towards carnitine insufficiency (p < 0.05) and carnitine deficiency (p < 0.001). No significant differences were observed between LGA newborns born to mothers with or without a history of gestational diabetes. This novel study describes a postnatal acylcarnitine profile in LGA with higher levels of C2, C3, total acylcarnitines, and total short-chain acylcarnitines that is characteristic of childhood and adult obesity and linked to an unhealthy metabolic phenotype.

AB - The performance of liquid crystal (LC) spatial light modulators depends critically on the amount of cumulative phase change. However, for regular phase modulators, a large phase change comes with a slow time response penalty. A multi layer liquid crystal (LC) spatial light modulator offers a large phase change while keeping fast response time due to the decoupling between phase change and time response through engineered sub-micron scaffold. Here, we demonstrate specially designed 2- and 3-layer LC cells which can achieve 4 times and 7 times faster response time than that of conventional single-layer LC phase modulator of equivalent thickness, respectively. A versatile two-photon laser lithography is employed for LC cell scaffolding to accurately verify theoretical predictions with experimental measurements.

AB - It is challenging to determine the ground states of heterofullerenes due to the numerous isomers. Taking the C60-n B n heterofullerenes (1 <= n <= 4) as an example, our first-principles calculations with the isomer enumeration present the most stable structure of C57B3, which is energetically favored by 0.73 eV than the reported counterpart. It was difficult to conduct the enumeration for the isomers with n beyond 4 because of the expensive first-principle calculations. Here, we propose a nomenclature to enhance structural recognition and adopt an extended cluster expansion to describe the structural stabilities, in which the energies of the heterofullerenes with various concentrations are predicted by linear combination of the multi-body interactions. Unlike the conventional cluster expansion, the interaction parameters are derived from the enumeration of C60-n B n (n = 1~4), where there are only 4 coefficients to be fitted as a function of composition for the consideration of local bonding. The cross-validation scores are 1~2 meV per atom for both C55B5 and C54B6, ensuring the ground states obtained from our model are in line with the first-principles results. With the help of the structural recognition, the extended cluster expansion could be further applied to other binary systems as an effective complement to the first-principle calculations. PMID- 29176730 TI - The microbiomes of blowflies and houseflies as bacterial transmission reservoirs. AB - Blowflies and houseflies are mechanical vectors inhabiting synanthropic environments around the world. They feed and breed in fecal and decaying organic matter, but the microbiome they harbour and transport is largely uncharacterized. We sampled 116 individual houseflies and blowflies from varying habitats on three continents and subjected them to high-coverage, whole-genome shotgun sequencing. This allowed for genomic and metagenomic analyses of the host-associated microbiome at the species level. Both fly host species segregate based on principal coordinate analysis of their microbial communities, but they also show an overlapping core microbiome. Legs and wings displayed the largest microbial diversity and were shown to be an important route for microbial dispersion. The environmental sequencing approach presented here detected a stochastic distribution of human pathogens, such as Helicobacter pylori, thereby demonstrating the potential of flies as proxies for environmental and public health surveillance. PMID- 29176733 TI - A pH-induced conformational switch in a tyrosine kinase inhibitor identified by electronic spectroscopy and quantum chemical calculations. AB - Tyrosine kinase inhibitors (TKIs) are a major class of drug utilised in the clinic. During transit to their cognate kinases, TKIs will encounter different pH environments that could have a major influence on TKI structure. To address this, we report UV-Vis spectroscopic and computational studies of the TKI, AG1478, as a function of pH. The electronic absorption spectrum of AG1478 shifted by 10 nm (from 342 nm to 332 nm) from acid to neutral pH and split into two peaks (at 334 nm and 345 nm) in highly alkaline conditions. From these transitions, the pKa value was calculated as 5.58 +/- 0.01. To compute structures and spectra, time dependent density functional theory (TD-DFT) calculations were performed along with conductor-like polarizable continuum model (CPCM) to account for implicit solvent effect. On the basis of the theoretical spectra, we could assign the AG1478 experimental spectrum at acidic pH to a mixture of two twisted conformers (71% AG1478 protonated at quinazolyl nitrogen N(1) and 29% AG1478 protonated at quinazolyl nitrogen N(3)) and at neutral pH to the neutral planar conformer. The AG1478 absorption spectrum (pH 13.3) was fitted to a mixture of neutral (70%) and NH-deprotonated species (30%). These studies reveal a pH-induced conformational transition in a TKI. PMID- 29176734 TI - Spectroscopic detection of halogen bonding resolves dye regeneration in the dye sensitized solar cell. AB - The interactions between a surface-adsorbed dye and a soluble redox-active electrolyte species in the dye-sensitized solar cell has a significant impact on the rate of regeneration of photo-oxidized dye molecules and open-circuit voltage of the device. Dyes must therefore be designed to encourage these interfacial interactions, but experimentally resolving how such weak interactions affect electron transfer is challenging. Herein, we use X-ray absorption spectroscopy to confirm halogen bonding can exist at the dye-electrolyte interface. Using a known series of triphenylamine-based dyes bearing halogen substituents geometrically positioned for reaction with halides in solution, halogen bonding was detected only in cases where brominated and iodinated dyes were photo-oxidized. This result implies that weak intermolecular interactions between photo-oxidized dyes and the electrolyte can impact device photovoltages. This result was unexpected considering the low concentration of oxidized dyes (less than 1 in 100,000) under full solar illumination. PMID- 29176735 TI - Interplay between trauma and Pseudomonas entomophila infection in flies: a central role of the JNK pathway and of CrebA. AB - In mammals, both sterile wounding and infection induce inflammation and activate the innate immune system, and the combination of both challenges may lead to severe health defects, revealing the importance of the balance between the intensity and resolution of the inflammatory response for the organism's fitness. Underlying mechanisms remain however elusive. Using Drosophila, we show that, upon infection with the entomopathogenic bacterium Pseudomonas entomophila (Pe), a sterile wounding induces a reduced resistance and increased host mortality. To identify the molecular mechanisms underlying the susceptibility of wounded flies to bacterial infection, we analyzed the very first steps of the process by comparing the transcriptome landscape of infected (simple hit flies, SH), wounded and infected (double hit flies, DH) and wounded (control) flies. We observed that overexpressed genes in DH flies compared to SH ones are significantly enriched in genes related to stress, including members of the JNK pathway. We demonstrated that the JNK pathway plays a central role in the DH phenotype by manipulating the Jra/dJun activity. Moreover, the CrebA/Creb3-like transcription factor (TF) and its targets were up-regulated in SH flies and we show that CrebA is required for mounting an appropriate immune response. Drosophila thus appears as a relevant model to investigate interactions between trauma and infection and allows to unravel key pathways involved. PMID- 29176736 TI - Rama: a machine learning approach for ribosomal protein prediction in plants. AB - Ribosomal proteins (RPs) play a fundamental role within all type of cells, as they are major components of ribosomes, which are essential for translation of mRNAs. Furthermore, these proteins are involved in various physiological and pathological processes. The intrinsic biological relevance of RPs motivated advanced studies for the identification of unrevealed RPs. In this work, we propose a new computational method, termed Rama, for the prediction of RPs, based on machine learning techniques, with a particular interest in plants. To perform an effective classification, Rama uses a set of fundamental attributes of the amino acid side chains and applies a two-step procedure to classify proteins with unknown function as RPs. The evaluation of the resultant predictive models showed that Rama could achieve mean sensitivity, precision, and specificity of 0.91, 0.91, and 0.82, respectively. Furthermore, a list of proteins that have no annotation in Phytozome v.10, and are annotated as RPs in Phytozome v.12, were correctly classified by our models. Additional computational experiments have also shown that Rama presents high accuracy to differentiate ribosomal proteins from RNA-binding proteins. Finally, two novel proteins of Arabidopsis thaliana were validated in biological experiments. Rama is freely available at http://inctipp.bioagro.ufv.br:8080/Rama . PMID- 29176738 TI - Induction of Immune Surveillance of the Dysmorphogenic Lens. AB - The lens has been considered to be an immune privileged site not susceptible to the immune processes normally associated with tissue injury and wound repair. However, as greater insight into the immune surveillance process is gained, we have reevaluated the concept of immune privilege. Our studies using an N-cadherin lens-specific conditional knockout mouse, N-cadDeltalens, show that loss of this cell-cell junctional protein leads to lens degeneration, necrosis and fibrotic change, postnatally. The degeneration of this tissue induces an immune response resulting in immune cells populating the lens that contribute to the development of fibrosis. Additionally, we demonstrate that the lens is connected to the lymphatic system, with LYVE(+) labeling reaching the lens along the suspensory ligaments that connect the lens to the ciliary body, providing a potential mechanism for the immune circulation. Importantly, we observe that degeneration of the lens activates an immune response throughout the eye, including cornea, vitreous humor, and retina, suggesting a coordinated protective response in the visual system to defects of a component tissue. These studies demonstrate that lens degeneration induces an immune response that can contribute to the fibrosis that often accompanies lens dysgenesis, a consideration for understanding organ system response to injury.

AB - ZnSO4?7H2O was prepared using a filter cake enriched in calcium and magnesium that was generated during the process of zinc hydrometallurgy. The study was optimized to obtain process parameters. The results show that the optimal acid leaching parameters are a solid-to-liquid ratio of 1:3.5, a sulfuric acid concentration of 16%, an acid leaching time of 20 min, a final pH of 4.1-4.4, a cooling and settling time of 120 min, an oxidation time of 20 min, a stirring speed of 300 r/min, a H2O2 dosage of 25 mL/L, a crystallization temperature of 20 degrees C, and a crystallization time of 60 min. The ZnSO4?7H2O content in the product is 98.6%, and the zinc recovery efficiency is 97.5%. This process is characterized by simple flow and low cost, while the circulation and accumulation problems with calcium and magnesium ions in the zinc hydrometallurgy process are also solved. PMID- 29176737 TI - cGAS drives noncanonical-inflammasome activation in age-related macular degeneration. AB - Geographic atrophy is a blinding form of age-related macular degeneration characterized by retinal pigmented epithelium (RPE) death; the RPE also exhibits DICER1 deficiency, resultant accumulation of endogenous Alu-retroelement RNA, and NLRP3-inflammasome activation. How the inflammasome is activated in this untreatable disease is largely unknown. Here we demonstrate that RPE degeneration in human-cell-culture and mouse models is driven by a noncanonical-inflammasome pathway that activates caspase-4 (caspase-11 in mice) and caspase-1, and requires cyclic GMP-AMP synthase (cGAS)-dependent interferon-beta production and gasdermin D-dependent interleukin-18 secretion. Decreased DICER1 levels or Alu-RNA accumulation triggers cytosolic escape of mitochondrial DNA, which engages cGAS. Moreover, caspase-4, gasdermin D, interferon-beta, and cGAS levels were elevated in the RPE in human eyes with geographic atrophy. Collectively, these data highlight an unexpected role of cGAS in responding to mobile-element transcripts, reveal cGAS-driven interferon signaling as a conduit for mitochondrial-damage induced inflammasome activation, expand the immune-sensing repertoire of cGAS and caspase-4 to noninfectious human disease, and identify new potential targets for treatment of a major cause of blindness.

AB - Interleukin-17 (IL-17), IL-21, IL-22 and IL-23 can be grouped as T helper 17 (Th17)-related cytokines because they are either produced by Th17/Th22 cells or involved in their development. Here, we review Th17-related cytokines/Th17-like cells, networks/signals and their roles in immune responses or immunity against Mycobacterium tuberculosis (Mtb) infection. Published studies suggest that Th17 related cytokine pathways may be manipulated by Mtb microorganisms for their survival benefits in primary tuberculosis (TB). In addition, there is evidence that immune responses of the signal transducer and activator of transcription 3 (STAT3) signal pathway and Th17-like T-cell subsets are dysregulated or destroyed in patients with TB. Furthermore, Mtb infection can impact upstream cytokines in the STAT3 pathway of Th17-like responses. Based on these findings, we discuss the need for future studies and the rationale for targeting Th17-related cytokines/signals as a potential adjunctive treatment. PMID- 29176751 TI - Mapping microscale wetting variations on biological and synthetic water-repellent surfaces. AB - Droplets slip and bounce on superhydrophobic surfaces, enabling remarkable functions in biology and technology. These surfaces often contain microscopic irregularities in surface texture and chemical composition, which may affect or even govern macroscopic wetting phenomena. However, effective ways to quantify and map microscopic variations of wettability are still missing, because existing contact angle and force-based methods lack sensitivity and spatial resolution. Here, we introduce wetting maps that visualize local variations in wetting through droplet adhesion forces, which correlate with wettability. We develop scanning droplet adhesion microscopy, a technique to obtain wetting maps with spatial resolution down to 10 um and three orders of magnitude better force sensitivity than current tensiometers. The microscope allows characterization of challenging non-flat surfaces, like the butterfly wing, previously difficult to characterize by contact angle method due to obscured view. Furthermore, the technique reveals wetting heterogeneity of micropillared model surfaces previously assumed to be uniform. PMID- 29176752 TI - A very large-scale microelectrode array for cellular-resolution electrophysiology. AB - In traditional electrophysiology, spatially inefficient electronics and the need for tissue-to-electrode proximity defy non-invasive interfaces at scales of more than a thousand low noise, simultaneously recording channels. Using compressed sensing concepts and silicon complementary metal-oxide-semiconductors (CMOS), we demonstrate a platform with 65,536 simultaneously recording and stimulating electrodes in which the per-electrode electronics consume an area of 25.5 MUm by 25.5 MUm. Application of this platform to mouse retinal studies is achieved with a high-performance processing pipeline with a 1 GB/s data rate. The platform records from 65,536 electrodes concurrently with a ~10 uV r.m.s. noise; senses spikes from more than 34,000 electrodes when recording across the entire retina; automatically sorts and classifies greater than 1700 neurons following visual stimulation; and stimulates individual neurons using any number of the 65,536 electrodes while observing spikes over the entire retina. The approaches developed here are applicable to other electrophysiological systems and electrode configurations. PMID- 29176750 TI - Chemoattractants and cytokines in primary ciliary dyskinesia and cystic fibrosis: key players in chronic respiratory diseases. AB - Patients with primary ciliary dyskinesia (PCD) and cystic fibrosis (CF), two inherited disorders, suffer from recurrent airway infections characterized by persistent bacterial colonization and uncontrollable inflammation. Although present in high counts, neutrophils fail to clear infection in the airways. High levels of C-X-C motif chemokine ligand 8/interleukin-8 (CXCL8/IL-8), the most potent chemokine to attract neutrophils to sites of infection, are detected in the sputum of both patient groups and might cause the high neutrophil influx in the airways. Furthermore, in CF, airway neutrophils are highly activated because of the genetic defect and the high levels of proinflammatory chemoattractants and cytokines (e.g., CXCL8/IL-8, tumor necrosis factor-alpha and IL-17). The overactive state of neutrophils leads to lung damage and fuels the vicious circle of infection, excessive inflammation and tissue damage. The inflammatory process in CF airways is well characterized, whereas the lung pathology in PCD is far less studied. The knowledge of CF lung pathology could be useful to guide molecular investigations of the inflammatory processes in PCD lungs. Current available therapies can not completely remedy the chronic airway infections in these diseases. This review gives an overview of the role that chemoattractants and cytokines play in these neutrophil-dominated lung pathologies. Finally, the most frequently applied treatments in CF and PCD and new experimental therapies to reduce neutrophil-dominated airway inflammation are described. PMID- 29176753 TI - Centiloid method evaluation for amyloid PET of subcortical vascular dementia. AB - Reference region selection is important for proper amyloid PET analysis, especially in subcortical vascular dementia (SVaD) patients. We investigated reference region differences between SVaD and Alzheimer's disease (AD) using Centiloid scores. In 57 [C-11] Pittsburgh compound B (PiB) positive (+) AD and 23 PiB (+) SVaD patients, we assessed standardized PiB uptake and Centiloid scores in disease-specific cortical regions, with several reference regions: cerebellar gray (CG), whole cerebellum (WC), WC with brainstem (WC + B), pons, and white matter (WM). We calculated disease group differences from young controls (YC) and YC variance according to reference region. SVaD patients showed large effect sizes (Cohen's d > 0.8) using all reference regions. WM and pons showed larger YC variances than other regions. Findings were similar for AD patients. CG, WC, and WC + B, but not WM or pons, are reliable reference regions for amyloid imaging analysis in SVaD. PMID- 29176754 TI - The O-specific polysaccharide lyase from the phage LKA1 tailspike reduces Pseudomonas virulence. AB - Pseudomonas phage LKA1 of the subfamily Autographivirinae encodes a tailspike protein (LKA1gp49) which binds and cleaves B-band LPS (O-specific antigen, OSA) of Pseudomonas aeruginosa PAO1. The crystal structure of LKA1gp49 catalytic domain consists of a beta-helix, an insertion domain and a C-terminal discoidin like domain. The putative substrate binding and processing site is located on the face of the beta-helix whereas the C-terminal domain is likely involved in carbohydrates binding. NMR spectroscopy and mass spectrometry analyses of degraded LPS (OSA) fragments show an O5 serotype-specific polysaccharide lyase specificity. LKA1gp49 reduces virulence in an in vivo Galleria mellonella infection model and sensitizes P. aeruginosa to serum complement activity. This enzyme causes biofilm degradation and does not affect the activity of ciprofloxacin and gentamicin. This is the first comprehensive report on LPS degrading lyase derived from a Pseudomonas phage. Biological properties reveal a potential towards its applications in antimicrobial design and as a microbiological or biotechnological tool. PMID- 29176755 TI - Baculovirus-Mediated miR-214 Knockdown Shifts Osteoporotic ASCs Differentiation and Improves Osteoporotic Bone Defects Repair. AB - Osteoporotic patients often suffer from bone fracture but its healing is compromised due to impaired osteogenesis potential of bone marrow-derived mesenchymal stem cells (BMSCs). Here we aimed to exploit adipose-derived stem cells from ovariectomized rats (OVX-ASCs) for bone healing. We unraveled that OVX ASCs highly expressed miR-214 and identified 2 miR-214 targets: CTNNB1 (beta catenin) and TAB2. We demonstrated that miR-214 targeting of these two genes blocked the Wnt pathway, led to preferable adipogenesis and hindered osteogenesis. As a result, OVX-ASCs implantation into OVX rats failed to heal critical-size metaphyseal bone defects. We further engineered the OVX-ASCs with a novel Cre/loxP-based hybrid baculovirus vector that conferred prolonged expression of miR-214 sponge. Gene delivery for miR-214 sponge expression successfully downregulated miR-214 levels, activated the Wnt pathway, upregulated osteogenic factors beta-catenin/Runx2, downregulated adipogenic factors PPAR gamma and C/EBP-alpha, shifted the differentiation propensity towards osteogenic lineage, enhanced the osteogenesis of co-cultured OVX-BMSCs, elevated BMP7/osteoprotegerin secretion and hindered exosomal miR-214/osteopontin release. Consequently, implanting the miR-214 sponge-expressing OVX-ASCs tremendously improved bone healing in OVX rats. Co-expression of miR-214 sponge and BMP2 further synergized the OVX-ASCs-mediated bone regeneration in OVX rats. This study implicates the potential of suppressing miR-214 by baculovirus-mediated gene delivery in osteoporotic ASCs for regenerative medicine. PMID- 29176756 TI - Cryogenic 3D Printing of Super Soft Hydrogels. AB - Conventional 3D bioprinting allows fabrication of 3D scaffolds for biomedical applications. In this contribution we present a cryogenic 3D printing method able to produce stable 3D structures by utilising the liquid to solid phase change of a composite hydrogel (CH) ink. This is achieved by rapidly cooling the ink solution below its freezing point using solid carbon dioxide (CO2) in an isopropanol bath. The setup was able to successfully create 3D complex geometrical structures, with an average compressive stiffness of O(1) kPa (0.49 +/- 0.04 kPa stress at 30% compressive strain) and therefore mimics the mechanical properties of the softest tissues found in the human body (e.g. brain and lung). The method was further validated by showing that the 3D printed material was well matched to the cast-moulded equivalent in terms of mechanical properties and microstructure. A preliminary biological evaluation on the 3D printed material, coated with collagen type I, poly-L-lysine and gelatine, was performed by seeding human dermal fibroblasts. Cells showed good attachment and viability on the collagen-coated 3D printed CH. This greatly widens the range of applications for the cryogenically 3D printed CH structures, from soft tissue phantoms for surgical training and simulations to mechanobiology and tissue engineering. PMID- 29176757 TI - Pseudomonas aeruginosa exoproducts determine antibiotic efficacy against Staphylococcus aureus. AB - Chronic coinfections of Staphylococcus aureus and Pseudomonas aeruginosa frequently fail to respond to antibiotic treatment, leading to significant patient morbidity and mortality. Currently, the impact of interspecies interaction on S. aureus antibiotic susceptibility remains poorly understood. In this study, we utilize a panel of P. aeruginosa burn wound and cystic fibrosis (CF) lung isolates to demonstrate that P. aeruginosa alters S. aureus susceptibility to bactericidal antibiotics in a variable, strain-dependent manner and further identify 3 independent interactions responsible for antagonizing or potentiating antibiotic activity against S. aureus. We find that P. aeruginosa LasA endopeptidase potentiates lysis of S. aureus by vancomycin, rhamnolipids facilitate proton-motive force-independent tobramycin uptake, and 2-heptyl-4 hydroxyquinoline N-oxide (HQNO) induces multidrug tolerance in S. aureus through respiratory inhibition and reduction of cellular ATP. We find that the production of each of these factors varies between clinical isolates and corresponds to the capacity of each isolate to alter S. aureus antibiotic susceptibility. Furthermore, we demonstrate that vancomycin treatment of a S. aureus mouse burn infection is potentiated by the presence of a LasA-producing P. aeruginosa population. These findings demonstrate that antibiotic susceptibility is complex and dependent not only upon the genotype of the pathogen being targeted, but also on interactions with other microorganisms in the infection environment. Consideration of these interactions will improve the treatment of polymicrobial infections. PMID- 29176758 TI - Early optimal parenteral nutrition and metabolic acidosis in very preterm infants. AB - BACKGROUND: It is currently recognized that an optimized nutritional approach, consisting of an early and substantial supply of protein and energy by parenteral route, may be beneficial for very low birth weight infants and recent guidelines endorse this strategy. However, the impact of the enhanced parenteral nutrition (PN) on acid-basic balance has never been investigated. The aim of the present study is to assess the effect of nutrient intake on acid-base homeostasis in a large population of preterm infants on PN. METHODS: This observational study described the acid-base profile of very preterm infants (<=29 week's gestation) receiving PN during the first week of life. For this purpose three different cohorts of infants who received increasing (group 1 to group 3) nutritional intakes were considered. Nutrition data were recorded daily and correlated to acid-base data (pH, base excess, and lactate). The outcome measure to assess metabolic acidosis was the base excess (BE). RESULTS: 161 infants were included. 1127 daily nutritional records and 795 blood gas data were analyzed. The three groups were different with regard to nutritional intravenous intakes. Group 3 in particular had a higher mean intake of both amino acids (3.3 +/- 0.8 g/kg/d) and lipids (2.8 +/- 1.4 g/kg/d) during the first week of life. Metabolic acidosis was more severe in the group with the highest parenteral intake of amino acids and lipids: mean BE = -8.7 +/- 3.4 (group 3); -6.4 +/- 3.4 (group 2); -5.1 +/- 3.0 (group 1)]. At the multivariate analysis the significant risk factors for metabolic acidosis were: gestational age, initial base excess, amino acid and lipid intravenous intakes. DISCUSSION: Acid-base homeostasis was influenced by the nutritional intake. Earlier and higher intravenous amino acid and lipid intakes particularly increased the risk of metabolic acidosis. The nutritional tolerance was different depending on gestational age, and the smaller infants (24 26 week's gestation) displayed greater acidotic disequilibrium and a higher need of bicarbonate. PMID- 29176759 TI - Distinct Trypanosoma cruzi isolates induce activation and apoptosis of human neutrophils. AB - Neutrophils are critical players in the first line of defense against pathogens and in the activation of subsequent cellular responses. We aimed to determine the effects of the interaction of Trypanosoma cruzi with human neutrophils, using isolates of the two major discrete type units (DTUs) associated with Chagas' disease in Latin America (clone Col1.7G2 and Y strain, DTU I and II, respectively). Thus, we used CFSE-stained trypomastigotes to measure neutrophil T. cruzi interaction, neutrophil activation, cytokine expression and death, after infection with Col1.7G2 and Y strain. Our results show that the frequency of CFSE+ neutrophils, indicative of interaction, and CFSE intensity on a cell-per cell basis were similar when comparing Col1.7G2 and Y strains. Interaction with T. cruzi increased neutrophil activation, as measured by CD282, CD284, TNF and IL 12 expression, although at different levels between the two strains. No change in IL-10 expression was observed after interaction of neutrophils with either strain. We observed that exposure to Y and Col1.7G2 caused marked neutrophil death. This was specific to neutrophils, since interaction of either strain with monocytes did not cause death. Our further analysis showed that neutrophil death was a result of apoptosis, which was associated with an upregulation of TNF receptor, TNF and FasLigand, but not of Fas. Induction of TNF-associated neutrophil apoptosis by the different T. cruzi isolates may act as an effective common mechanism to decrease the host's immune response and favor parasite survival. PMID- 29176760 TI - Clostridium difficile flagellin FliC: Evaluation as adjuvant and use in a mucosal vaccine against Clostridium difficile. AB - The immunogenicity of bacterial flagellin has been reported in different studies. By its close interaction with the immune system, the flagellin represents an interesting adjuvant and vaccine candidate. Salmonella Typhimurium flagellin has already been tested as adjuvant to stimulate mucosal immunity. Here, we assessed the ability of Clostridium difficile flagellin FliC to act as a mucosal adjuvant, first combined with ovalbumin as antigen and second with a C. difficile surface protein, the precursor of the S-layer proteins SlpA. Using ovalbumin as antigen, we compared the gut mucosal adjuvanticity of FliC to Salmonella Typhimurium flagellin and cholera toxin. Two routes of immunization were tested in a mouse model: intra-rectal and intra-peritoneal, following which, gut mucosal and systemic antibody responses against ovalbumin (Immunoglobulins G and Immunoglobulins A) were analyzed by Enzyme-Linked Immuno Assay in intestinal contents and in sera. In addition, ovalbumin-specific immunoglobulin producing cells were detected in the intestinal lamina propria by Enzyme-Linked Immunospot. Results showed that FliC as adjuvant for immunization targeting ovalbumin was able to stimulate a gut mucosal and systemic antibody response independently of the immunization route. In order to develop a mucosal vaccine to prevent C. difficile intestinal colonization, we assessed in a mouse model the efficacy of FliC as adjuvant compared with cholera toxin co-administrated with the C. difficile S-layer precursor SlpA as antigen. After challenge, a significant decrease of C. difficile intestinal colonization was observed in immunized groups compared to the control group. Our results showed that C. difficile FliC could be used as adjuvant in mucosal vaccination strategy against C. difficile infections. PMID- 29176761 TI - Association of objectively measured arm inclination with shoulder pain: A 6-month follow-up prospective study of construction and health care workers. AB - OBJECTIVES: The aim was to determine the association of occupational arm inclination with shoulder pain in construction and health care workers. METHODS: Arm inclination relative to the vertical was measured with an accelerometer placed on the dominant upper arm for up to four full days at baseline in 62 construction workers and 63 health care workers. The pain intensity in the shoulder and mechanical and psychosocial work factors were measured by self reports at baseline and prospectively after 6 months. The associations between exposures and shoulder pain were analyzed with multilevel mixed-effects linear regressions. RESULTS: For the total study population working with the dominant arm at inclinations > 30 degrees and >120 degrees was associated with lower levels of shoulder pain both cross-sectionally and after 6 months. Associations were attenuated when adjusting for individual and social factors, psychological state, and exposure during leisure time, especially for the high inclination levels. Analyses, only including subjects with no pain at baseline revealed no significant associations. While stratified analysis showed negative associations in the construction worker group, there were no significant association in health care workers. Compared to the number of hypotheses tested, the number of significant findings was low. Adjustment by Bonferroni-correction made almost all findings insignificant. CONCLUSIONS: All analyses reflected a negative association between arm inclination and shoulder pain, but few analyses showed these associations to be statistically significant. If there is a relationship between arm inclination and shoulder pain, these findings could indicate that pain-avoidance may modify how workers perform their tasks. PMID- 29176762 TI - Effect of a prenatal lifestyle intervention on physical activity level in late pregnancy and the first year postpartum. AB - BACKGROUND: Despite documented health benefits for mother and baby, physical activity (PA)-level tends to decline in pregnancy. Overweight/obese and physically inactive women are two selected groups at increased risk of pregnancy complications. Thus, efficient strategies to maintain or increase PA-level in pregnancy and the postpartum period, especially among these women, are warranted. This secondary analysis examined the effect of a prenatal lifestyle-intervention on PA-level in late pregnancy and the first year postpartum, with subanalysis on initially physically active versus inactive and normal-weight versus overweight/obese women. METHOD: The Norwegian Fit for Delivery (NFFD) randomized controlled trial included healthy primiparous women with singleton pregnancies and body mass index (BMI) >=19 kg/m2 assigned to an intervention group, n = 303 (twice weekly group-exercises and dietary counseling) or a control group, n = 303 (standard prenatal care). The International Physical Activity Questionnaire short form was used to assess PA-levels at inclusion (mean gestational week (GW) 16), GW 36, and six and 12 months postpartum. RESULTS: At GW 36, a positive intervention-effect with a significant between-group difference in total PA-level compared to time of inclusion was found for the total group (530 MET-min/week, p = 0.001) and the subgroups of normal-weight (533 MET-min/week, p = 0.003) and initially active women (717 MET-min/week, p<0.001). Intervention-effect was dependent on exercise-adherence among overweight/obese and inactive women. Compared to time of inclusion, the intervention groups maintained total PA-level at GW 36, while total PA-level decreased in the control groups. The PA-levels increased postpartum, but with no significant differences between the randomization groups. CONCLUSION: The NFFD prenatal combined lifestyle intervention had a significant effect on TPA-level in late pregnancy among women entering pregnancy normal-weight or physically active, thereby preventing the downward trend typically seen during pregnancy. Intervention-effect among overweight/obese and physically inactive women was, however, dependent on exercise-adherence. Long-term intervention-effect was not observed in the postpartum period. PMID- 29176763 TI - Blood serum metabolome of atopic dermatitis: Altered energy cycle and the markers of systemic inflammation. AB - Atopic dermatitis is a chronic inflammatory disease which usually starts in the early childhood and ends before adulthood. However up to 3% of adults remain affected by the disease. The onset and course of the disease is influenced by various genetic and environmental factors. Although the immune system has a great effect on the outcome of the disease, metabolic markers can also try to explain the background of atopic dermatitis. In this study we analyzed the serum of patients with atopic dermatitis using both targeted and untargeted metabolomics approaches. We found the most significant changes to be related to phosphatidylcholines, acylcarnitines and their ratios and a cleavage peptide of Fibrinogen A-alpha. These findings that have not been reported before will further help to understand this complex disease. PMID- 29176764 TI - Interleukin 27 is increased in carotid atherosclerosis and promotes NLRP3 inflammasome activation. AB - AIM: Interleukin-27 (IL-27) is involved in different inflammatory diseases; however, its role in atherosclerosis is unclear. In this study we investigated the expression of IL-27 and its receptor in patients with carotid atherosclerosis and if IL-27 could modulate the inflammatory effects of the NLRP3 inflammasome in vitro. METHODS: Plasma IL-27 was measured by enzyme immunoassay in patients with carotid stenosis (n = 140) and in healthy controls (n = 19). Expression of IL-27 and IL-27R was analyzed by quantitative PCR and immunohistochemistry in plaques from patients and in non-atherosclerotic vessels. THP-1 monocytes, primary monocytes and peripheral blood mononuclear cells (PBMCs) were used to study effects of IL-27 in vitro. RESULTS: Our main findings were: (i) Plasma levels of IL-27 were significantly elevated in patients with carotid atherosclerotic disease compared to healthy controls. (ii) Gene expression of IL-27 and IL-27R was significantly elevated in plaques compared to control vessels, and co localized to macrophages. (iii) In vitro, IL-27 increased NLRP3 inflammasome activation in monocytes with enhanced release of IL-1 beta. CONCLUSIONS: We demonstrate increased levels of IL-27 and IL-27R in patients with carotid atherosclerosis. Our in vitro findings suggest an inflammatory role for IL-27, which can possibly be linked to atherosclerotic disease development. PMID- 29176765 TI - Protection of mice deficient in mature B cells from West Nile virus infection by passive and active immunization. AB - B cell activating factor receptor (BAFFR)-/- mice have a profound reduction in mature B cells, but unlike MUMT mice, they have normal numbers of newly formed, immature B cells. Using a West Nile virus (WNV) challenge model that requires antibodies (Abs) for protection, we found that unlike wild-type (WT) mice, BAFFR /- mice were highly susceptible to WNV and succumbed to infection within 8 to 12 days after subcutaneous virus challenge. Although mature B cells were required to protect against lethal infection, infected BAFFR-/- mice had reduced WNV E specific IgG responses and neutralizing Abs. Passive transfer of immune sera from previously infected WT mice rescued BAFFR-/- and fully B cell-deficient MUMT mice, but unlike MUMT mice that died around 30 days post-infection, BAFFR-/- mice survived, developed WNV-specific IgG Abs and overcame a second WNV challenge. Remarkably, protective immunity could be induced in mature B cell-deficient mice. Administration of a WNV E-anti-CD180 conjugate vaccine 30 days prior to WNV infection induced Ab responses that protected against lethal infection in BAFFR-/ mice but not in MUMT mice. Thus, the immature B cells present in BAFFR-/- and not MUMT mice contribute to protective antiviral immunity. A CD180-based vaccine may promote immunity in immunocompromised individuals. PMID- 29176766 TI - Establishment of an indirect ELISA for detection of the novel antifibrotic peptide M10. AB - OBJECTIVE: M10 is a ten amino acid peptide generated from the intracellular cytoplasmic tail of the hepatocyte growth factor (HGF) receptor c-Met following cleavage by caspase-3. Recently we reported that M10 interacts with Smad2 and demonstrates antifibrotic properties in vitro and in vivo and can be advanced into a novel antifibrotic remedy. The current study was undertaken to develop an immunoassay to measure M10 concentration in biological specimens. EXPERIMENTAL DESIGN: An Indirect Enzyme-Linked Immunosorbent Assay (ELISA) for detection of M10 in biological fluids was developed using pharmaceutical grade synthetic M10 as a calibrator and commercially available anti-c-Met C12 antibody. RESULTS: M10 ELISA specifically detected in plasma M10, but not a scrambled peptide, following a single intraperitoneal administration of M10 (1mg/kg) to mice. The detection limit was 9.6 ng/ml, and the measuring limit was between 15 ng/ml and 200 ng/ml. The recovery limits of M10 were between 80% and 120%; intra-assay coefficient of variation was between 5.3% and 6.3%; inter-assay coefficient of variation was between 5.0% and 8.0% over the buffer concentration tested in the range from 15 ng /ml to 250 ng /ml. The peak of M10 concentration following a single intraperitoneal injection (1mg/kg) was achieved within 6 hours and declined to minimal levels by 48 hours. The experimentally obtained half-life for M10 was comparable to the theoretically predicted half-life for M10. CONCLUSIONS: We have established a highly sensitive ELISA to detect the antifibrotic peptide M10 in plasma samples, which should prove to be a novel tool to study the pharmacokinetics and efficacy of M10 in the treatment of fibroproliferative disorders. PMID- 29176768 TI - Employing open/hidden administration in psychotherapy research: A randomized controlled trial of expressive writing. AB - : Psychotherapy has been shown to be effective, but efforts to prove specific effects by placebo-controlled trials have been practically and conceptually hampered. We propose that adopting open/hidden designs from placebo research would offer a possible way to establish specificity in psychotherapy. Therefore, we tested the effects of providing opposing treatment rationales in an online expressive writing intervention on affect in healthy subjects. Results indicate that it was possible to conduct the expressive writing intervention both covertly and openly, but that participants in the hidden administration condition did not fully benefit from the otherwise effective expressive writing intervention in the long-run. Effect sizes between open and hidden administration groups were comparable to pre-post effect sizes of the intervention. While this finding is important for the understanding of psychotherapy's effects per se, it also proves that alternative research approaches to establish specificity are feasible and informative in psychotherapy research. TRIAL REGISTRATION: German Clinical Trials Register DRKS00009428. PMID- 29176767 TI - H1N1 influenza virus infection results in adverse pregnancy outcomes by disrupting tissue-specific hormonal regulation. AB - Increased susceptibility to influenza virus infection during pregnancy has been attributed to immunological changes occurring before and during gestation in order to "tolerate" the developing fetus. These systemic changes are most often characterized by a suppression of cell-mediated immunity and elevation of humoral immune responses referred to as the Th1-Th2 shift. However, the underlying mechanisms which increase pregnant mothers' risk following influenza virus infection have not been fully elucidated. We used pregnant BALB/c mice during mid to late gestation to determine the impact of a sub-lethal infection with A/Brisbane/59/07 H1N1 seasonal influenza virus on completion of gestation. Maternal and fetal health status was closely monitored and compared to infected non-pregnant mice. Severity of infection during pregnancy was correlated with premature rupture of amniotic membranes (PROM), fetal survival and body weight at birth, lung viral load and degree of systemic and tissue inflammation mediated by innate and adaptive immune responses. Here we report that influenza virus infection resulted in dysregulation of inflammatory responses that led to pre term labor, impairment of fetal growth, increased fetal mortality and maternal morbidity. We observed significant compartment-specific immune responses correlated with changes in hormonal synthesis and regulation. Dysregulation of progesterone, COX-2, PGE2 and PGF2alpha expression in infected pregnant mice was accompanied by significant remodeling of placental architecture and upregulation of MMP-9 early after infection. Collectively these findings demonstrate the potential of a seasonal influenza virus to initiate a powerful pro-abortive mechanism with adverse outcomes in fetal health. PMID- 29176769 TI - Decreased prevalence of cancer in patients with multiple sclerosis: A case control study. AB - BACKGROUND: Studies of cancer prevalence have produced conflicting results concerning the relative risk of overall and specific sub-types of cancer in patients with multiple sclerosis (MS). Contemporary controls and information on tobacco use and alcohol consumption are generally missing from previous studies. OBJECTIVES: To evaluate lifetime cancer prevalence in a large cohort of MS patients relative to appropriate controls. METHODS: We conducted a case-control study, using a postal survey of a cohort of MS patients. Of the 1574 questionnaires sent, 1107 could be used for statistical analysis. Data from 1568 controls were prospectively collected using the same self-administered survey among consecutive out-patients in a single neurology department. Propensity scores matched on age, gender, and history of smoking and alcohol consumption were calculated. RESULTS: Among the MS patients, 7.32% had ever presented with a cancer, whereas 12,63% of the controls had, leading to a bootstrap matched odds ratio (OR) of 0.63; 95% CI 0.57-0.70. Although only exploratory, the use of DMT (immunomodulators or immunosupressants) did not appear to increase this risk (p = 0.42). The disease course also did not affect cancer prevalence. CONCLUSION: MS was associated with a reduced overall cancer risk. PMID- 29176771 TI - Multiple factors contribute to reproductive isolation between two co-existing Habenaria species (Orchidaceae). AB - Reproductive isolation is a key feature that forms barriers to gene flow between distinct plants. In orchids, prezygotic reproductive isolation has been considered to be strong, because their associations with highly specific pollinators. In this study, the reproductive ecology and reproductive isolation of two sympatric Habenaria species, H. davidii and H. fordii, was investigated by floral phenology and morphology, hand-pollination experiments and visitor observation in southwest China. The two species were dependent on insects for pollination and completely self-compatible. A number of factors have been identified to limit gene flow between the two species and achieved full reproductive isolation. Ecogeographic isolation was a weak barrier. H. fordii and H. davidii had completely overlapped flowering periods, and floral morphology plays an important role in floral isolation. The two species shared the same hawkmoth pollinator, Cechenena lineosa, but the pollinaria of the two orchids were attached on different body parts of pollinators. Prezygotic isolation was not complete, but the interspecific pollination treatments of each species resulted in no seed sets, indicating that unlike many other orchid species, in which the postzygotic reproductive isolation is very weak or complete absence, the post-zygotic isolation strongly acted in the stage of seed production between two species. The results illustrate the reproductive isolation between two species involves multiple plant life-history stages and a variety of reproductive barriers can contribute to overall isolation. PMID- 29176770 TI - High Trypanosoma spp. diversity is maintained by bats and triatomines in Espirito Santo state, Brazil. AB - The aim of this study was to reevaluate the ecology of an area in the Atlantic Forest, southeast Brazil, where Chagas disease (CD) has been found to occur. In a previous study, immediately after the occurrence of a CD case, we did not observe any sylvatic small mammals or dogs with Trypanosoma cruzi cruzi infections, but Triatoma vitticeps presented high T. c. cruzi infection rates. In this study, we investigated bats together with non-volant mammals, dogs, and triatomines to explore other possible T. c. cruzi reservoirs/hosts in the area. Seventy-three non-volant mammals and 186 bats were captured at three sites within the Guarapari municipality, Espirito Santo state. Rio da Prata and Amarelos sites exhibited greater richness in terms of non-volant mammals and bats species, respectively. The marsupial Metachirus nudicaudatus, the rodent Trinomys paratus, and the bats Artibeus lituratus and Carollia perspicillata were the most frequently captured species. As determined by positive hemocultures, only two non-volant mammals were found to be infected by Trypanosoma species: Monodelphis americana, which was infected by T. cascavelli, T. dionisii and Trypanosoma sp., and Callithrix geoffroyi, which was infected by T. minasense. Bats presented T. c. cruzi TcI and TcIII/V, T. c. marinkellei, T. dionisii, T. rangeli B and D, and Trypanosoma sp. infections. Seven dogs were infected with T. cruzi based only on serological exams. The triatomines T. vitticeps and Panstrongylus geniculatus were found to be infected by trypanosomes via microscopy. According to molecular characterization, T. vitticeps specimens were infected with T. c. cruzi TcI, TcII, TcIII/V, and TcIV, T. c. marinkellei and T. dionisii. We observed high trypanosome diversity in a small and fragmented region of the Atlantic Forest. This diversity was primarily maintained by bats and T. vitticeps. Our findings show that the host specificity of the Trypanosoma genus should be thoroughly reviewed. In addition, our data show that CD cases can occur without an enzootic cycle near residential areas. PMID- 29176772 TI - Symphyseal fixation in open book injuries cannot fully compensate anterior SI joint injury-A biomechanical study in a two-leg alternating load model. AB - INTRODUCTION: In open book injuries type Tile B1.1 or B1.2 also classified as APC II (anteroposterior compression), it remains controversial, if a fixation of the anterior ring provides sufficient stability or a fixation of the posterior ring should be included. Therefore the relative motion at the sacroiliac joint was quantified in a two-leg alternating load biomechanical pelvis model in the intact, the injured and the restored pelvis. METHODS: Fresh-frozen intact (I) pelvises (n = 6) were subjected to a non-destructive cyclic test under sinosuidal axial two-leg alternating load with progressively increasing amplitude. Afterwards an open book injury (J) including the anterior ligament complex of the left sacroiliac joint, the sacrospinal and sacrotuberal ligaments (Tile B1.1) was created and the specimens were retested. Finally, the symphysis was stabilized with a modular fixation system (1-, 2- or 4-rod configuration) (R) and specimens were cyclically retested. Relative motion at the sacroiliac joint was captured at both sacroiliac joints by motion tracking system at two load levels of 170 N and 340 N during all tests. RESULTS: Relative sacroiliac joint movements at both load levels were significantly higher in the J-state compared to the I-state, excluding superoinferior translational movement. With exception of the anteroposterior translational movement at 340N, the relative sacroiliac joint movements after each of the three reconstructions (1-, 2-, 4-rod fixation) were significantly smaller compared to the J-state and did not differ significantly to the I-state, but stayed above the values of the latter. Relative movements did not differ significantly in a direct comparison between the 1-rod, 2-rod and 4 rod fixations. CONCLUSION: Symphyseal locked plating significantly reduces relative movement of the sacroiliac joint in open book injuries type Tile B1.1 or B1.2 (APC II) but cannot fully restore the situation of the intact sacroiliac joint. PMID- 29176773 TI - Reflectance, absorbance and transmittance spectra of bermudagrass and manilagrass turfgrass canopies. AB - Leaves act as a primary organ for the interception of solar radiation and their spatial arrangement determines how the plant canopy interacts with light. Many studies have been carried out on the penetration of radiation into crops however to date, few results are available on turfgrasses, mainly due to the difficulties of introducing sensors into the turf without disturbing the natural position of the leaves. In the present research two warm season turfgrasses, hybrid bermudagrass (Cynodon dactylon * transvaalensis) 'Patriot' and manilagrass (Zoysia matrella) 'Zeon', were studied. The aim was to describe their canopy architecture grown with minimal disturbance to the natural arrangement of the leaves and stems, and to determine the potential effects of canopy architecture on light penetration and reflectance. Radiometric measurements were carried out at eight different profile levels of turfgrasses that were up to 12 cm tall. A LI COR 1800 spectroradiometer with an optical fiber cable and a 7 mm diameter sensor was used. Measurements were carried out in the 390-1100 nm region at 5 nm intervals. The LAI value was higher for the manilagrass (9.0) than for the hybrid bermudagrass (5.6). The transmitted radiation was found to be closely dependent on downward cumulative LAI. Despite a more upright habit (mean insertion angle of 22.4 degrees +/-3.4), Zoysia matrella showed a higher NIR reflectance compared to Cdxt, which has a horizontal leaf arrangement (mean insertion angle 62.1 degrees +/- 9.6). The species studied showed substantial differences both in terms of phytometric characteristics and in the capacity to attenuate solar radiation. PMID- 29176774 TI - Epithelial rotation is preceded by planar symmetry breaking of actomyosin and protects epithelial tissue from cell deformations. AB - Symmetry breaking is involved in many developmental processes that form bodies and organs. One of them is the epithelial rotation of developing tubular and acinar organs. However, how epithelial cells move, how they break symmetry to define their common direction, and what function rotational epithelial motions have remains elusive. Here, we identify a dynamic actomyosin network that breaks symmetry at the basal surface of the Drosophila follicle epithelium of acinar like primitive organs, called egg chambers, and may represent a candidate force generation mechanism that underlies the unidirectional motion of this epithelial tissue. We provide evidence that the atypical cadherin Fat2, a key planar cell polarity regulator in Drosophila oogenesis, directs and orchestrates transmission of the intracellular actomyosin asymmetry cue onto a tissue plane in order to break planar actomyosin symmetry, facilitate epithelial rotation in the opposite direction, and direct the elongation of follicle cells. In contrast, loss of this rotational motion results in anisotropic non-muscle Myosin II pulses that are disorganized in plane and causes cell deformations in the epithelial tissue of Drosophila eggs. Our work demonstrates that atypical cadherins play an important role in the control of symmetry breaking of cellular mechanics in order to facilitate tissue motion and model epithelial tissue. We propose that their functions may be evolutionarily conserved in tubular/acinar vertebrate organs. PMID- 29176775 TI - Investigating dye performance and crosstalk in fluorescence enabled bioimaging using a model system. AB - Detailed imaging of biological structures, often smaller than the diffraction limit, is possible in fluorescence microscopy due to the molecular size and photophysical properties of fluorescent probes. Advances in hardware and multiple providers of high-end bioimaging makes comparing images between studies and between research groups very difficult. Therefore, we suggest a model system to benchmark instrumentation, methods and staining procedures. The system we introduce is based on doped zeolites in stained polyvinyl alcohol (PVA) films: a highly accessible model system which has the properties needed to act as a benchmark in bioimaging experiments. Rather than comparing molecular probes and imaging methods in complicated biological systems, we demonstrate that the model system can emulate this complexity and can be used to probe the effect of concentration, brightness, and cross-talk of fluorophores on the detected fluorescence signal. The described model system comprises of lanthanide (III) ion doped Linde Type A zeolites dispersed in a PVA film stained with fluorophores. We tested: F18, MitoTracker Red and ATTO647N. This model system allowed comparing performance of the fluorophores in experimental conditions. Importantly, we here report considerable cross-talk of the dyes when exchanging excitation and emission settings. Additionally, bleaching was quantified. The proposed model makes it possible to test and benchmark staining procedures before these dyes are applied to more complex biological systems. PMID- 29176776 TI - Understanding heart rate alarm adjustment in the intensive care units through an analytical approach. AB - BACKGROUND: Heart rate (HR) alarms are prevalent in ICU, and these parameters are configurable. Not much is known about nursing behavior associated with tailoring HR alarm parameters to individual patients to reduce clinical alarm fatigue. OBJECTIVES: To understand the relationship between heart rate (HR) alarms and adjustments to reduce unnecessary heart rate alarms. METHODS: Retrospective, quantitative analysis of an adjudicated database using analytical approaches to understand behaviors surrounding parameter HR alarm adjustments. Patients were sampled from five adult ICUs (77 beds) over one month at a quaternary care university medical center. A total of 337 of 461 ICU patients had HR alarms with 53.7% male, mean age 60.3 years, and 39% non-Caucasian. Default HR alarm parameters were 50 and 130 beats per minute (bpm). The occurrence of each alarm, vital signs, and physiologic waveforms was stored in a relational database (SQL server). RESULTS: There were 23,624 HR alarms for analysis, with 65.4% exceeding the upper heart rate limit. Only 51% of patients with HR alarms had parameters adjusted, with a median upper limit change of +5 bpm and -1 bpm lower limit. The median time to first HR parameter adjustment was 17.9 hours, without reduction in alarms occurrence (p = 0.57). CONCLUSIONS: HR alarms are prevalent in ICU, and half of HR alarm settings remain at default. There is a long delay between HR alarms and parameters changes, with insufficient changes to decrease HR alarms. Increasing frequency of HR alarms shortens the time to first adjustment. Best practice guidelines for HR alarm limits are needed to reduce alarm fatigue and improve monitoring precision. PMID- 29176777 TI - Risk of recurrence in chronic hepatitis B patients developing hepatocellular carcinoma with antiviral secondary prevention failure. AB - BACKGROUND: Nucleos(t)ide analogues (NUCs) treatment can reduce the risk of hepatocellular carcinoma (HCC) development and recurrence in chronic hepatitis B (CHB) patients. However, the risk of recurrence in CHB patients who develop HCC despite NUC treatment remains unclear. METHODS: 167 consecutive CHB patients receiving curative resection for HCC with NUC therapy after surgery were retrospectively enrolled. Thirty-eight patients who developed HCC despite NUC therapy for more than 1 year were defined as secondary prevention failure. The other 129 patients started NUC therapy after surgery. Factors associated with recurrence-free survival (RFS) and overall survival (OS) were evaluated. RESULTS: The 5-year RFS and OS rates were 44.7% and 77.3%, respectively. Sex, BMI, BCLC stage, AFP levels and cirrhosis status were the independent predictors of RFS, while microvascular invasion was the independent predictor of OS. The RFS was comparable between patients with and without NUC secondary prevention. In the subgroup analysis, the RFS was significantly worse in cirrhotic patients with secondary prevention failure (hazard ratio = 2.373, p = 0.009). Secondary prevention failure did not have adverse impact on OS. Among 84 patients with recurrence, 58.3% of the cases remained in BCLC stage A, and 53.6% received a second curative treatment. Long-term NUC therapy may lead to a decline of non invasive indices of hepatic fibrosis in HCC patients. CONCLUSIONS: In general, the risk of recurrence and survival are comparable between patients with and without secondary prevention failure. However, a higher risk of recurrence was observed in cirrhotic patients with secondary prevention failure. PMID- 29176778 TI - Cross-sectional interview study of fertility, pregnancy, and urogenital schistosomiasis in coastal Kenya: Documented treatment in childhood is associated with reduced odds of subfertility among adult women. AB - BACKGROUND: Previous research has documented an increased risk of subfertility in areas of sub-Saharan Africa, as well as an ecological association between urogenital schistosomiasis prevalence and decreased fertility. This pilot project examined reproductive patterns and the potential effects of childhood urogenital Schistosoma haematobium infection and individual treatment experience on adult subfertility among women who were long-term residents in an S. haematobium endemic region of coastal Kenya. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed findings from 162 in-depth interviews with women of childbearing age in a rural, coastal community, linking them, if possible, to their individual treatment records from previous multi-year longitudinal studies of parasitic infections. Reproductive histories indicated a much local higher local rate of subfertility (44%) than worldwide averages (8-12%). Although, due to the very high regional prevalence of schistosomiasis, a clear relationship could not be demonstrated between a history of S. haematobium infection and adult subfertility, among a convenience sub-sample of 61 women who had received documented treatment during previous interventional trials, a significant association was found between age at first anti-schistosomal treatment and later fertility in adulthood, with those women treated before age 21 significantly less likely to have subfertility (P = 0.001). CONCLUSIONS/SIGNIFICANCE: The high subfertility rate documented in this pilot study suggests the importance of programs to prevent and treat pelvic infections in their early stages to preclude reproductive tract damage. The available documented treatment data also suggest that early anti-schistosomal treatment may prevent the fertility-damaging effects of urogenital schistosomiasis, and lend support for programs that provide universal treatment of children in S. haematobium-endemic regions. PMID- 29176779 TI - Maternal-Fetal rejection reactions are unconstrained in preeclamptic women. AB - The risk factors for preeclampsia, extremes of maternal age, changing paternity, concomitant maternal autoimmunity, and/or birth intervals greater than 5 years, suggest an underlying immunopathology. We used peripheral blood and lymphocytes from the UteroPlacental Interface (UPI) of 3rd trimester healthy pregnant women in multicolor flow cytometry-and in vitro suppression assays. The major end-point was the characterization of activation markers, and potential effector functions of different CD4-and CD8 subsets as well as T regulatory cells (Treg). We observed a significant shift of peripheral CD4 -and CD8- T cells from naive to memory phenotype in preeclamptic women compared to healthy pregnant women consistent with long-standing immune activation. While the proportions of the highly suppressive Cytokine and Activated Treg were increased in preeclampsia, Treg tolerance toward fetal antigens was dysfunctional. Thus, our observations indicate a long-standing inflammatory derangement driving immune activation in preeclampsia; in how far the Treg dysfunction is caused by/causes this immune activation in preeclampsia will be the object of future studies.

AB - The iterative closest point (ICP) algorithm is efficient and accurate for rigid registration but it needs the good initial parameters. It is easily failed when the rotation angle between two point sets is large. To deal with this problem, a new objective function is proposed by introducing a rotation invariant feature based on the Euclidean distance between each point and a global reference point, where the global reference point is a rotation invariant. After that, this optimization problem is solved by a variant of ICP algorithm, which is an iterative method. Firstly, the accurate correspondence is established by using the weighted rotation invariant feature distance and position distance together. Secondly, the rigid transformation is solved by the singular value decomposition method. Thirdly, the weight is adjusted to control the relative contribution of the positions and features. Finally this new algorithm accomplishes the registration by a coarse-to-fine way whatever the initial rotation angle is, which is demonstrated to converge monotonically. The experimental results validate that the proposed algorithm is more accurate and robust compared with the original ICP algorithm. PMID- 29176781 TI - 1HNMR-Based metabolomic profiling method to develop plasma biomarkers for sensitivity to chronic heat stress in growing pigs. AB - The negative impact of heat stress (HS) on the production performances in pig faming is of particular concern. Novel diagnostic methods are needed to predict the robustness of pigs to HS. Our study aimed to assess the reliability of blood metabolome to predict the sensitivity to chronic HS of 10 F1 (Large White * Creole) sire families (SF) reared in temperate (TEMP) and in tropical (TROP) regions (n = 56+/-5 offsprings/region/SF). Live body weight (BW) and rectal temperature (RT) were recorded at 23 weeks of age. Average daily feed intake (AFDI) and average daily gain were calculated from weeks 11 to 23 of age, together with feed conversion ratio. Plasma blood metabolome profiles were obtained by Nuclear Magnetic Resonance spectroscopy (1HNMR) from blood samples collected at week 23 in TEMP. The sensitivity to hot climatic conditions of each SF was estimated by computing a composite index of sensitivity (Isens) derived from a linear combination of t statistics applied to familial BW, ADFI and RT in TEMP and TROP climates. A model of prediction of sensitivity was established with sparse Partial Least Square Discriminant Analysis (sPLS-DA) between the two most robust SF (n = 102) and the two most sensitive ones (n = 121) using individual metabolomic profiles measured in TEMP. The sPLS-DA selected 29 buckets that enabled 78% of prediction accuracy by cross-validation. On the basis of this training, we predicted the proportion of sensitive pigs within the 6 remaining families (n = 337). This proportion was defined as the predicted membership of families to the sensitive category. The positive correlation between this proportion and Isens (r = 0.97, P < 0.01) suggests that plasma metabolome can be used to predict the sensitivity of pigs to hot climate. PMID- 29176782 TI - A universal mammalian vaccine cell line substrate. AB - Using genome-wide small interfering RNA (siRNA) screens for poliovirus, influenza A virus and rotavirus, we validated the top 6 gene hits PV, RV or IAV to search for host genes that when knocked-down (KD) enhanced virus permissiveness and replication over wild type Vero cells or HEp-2 cells. The enhanced virus replication was tested for 12 viruses and ranged from 2-fold to >1000-fold. There were variations in virus-specific replication (strain differences) across the cell lines examined. Some host genes (CNTD2, COQ9, GCGR, NDUFA9, NEU2, PYCR1, SEC16G, SVOPL, ZFYVE9, and ZNF205) showed that KD resulted in enhanced virus replication. These findings advance platform-enabling vaccine technology, the creation of diagnostic cells substrates, and are informative about the host mechanisms that affect virus replication in mammalian cells. PMID- 29176783 TI - Association of parathyroid hormone and vitamin D with untreated hypertension: Is it different in white-coat or sustained hypertension? AB - BACKGROUND: Previous reports about the relationship between a high parathyroid hormone (PTH) and low vitamin D levels with blood pressure in different hypertension groups are conflicting. OBJECTIVE: We studied serum PTH and vitamin D levels in white-coat (WCHT) and sustained hypertension (SHT) patients who had not been on antihypertensive treatment. We also investigated the association between serum PTH and vitamin D levels with respect to blood pressure in SHT and WCHT patients. METHODS: We included 52 SHT patients (54.06 +/- 9.2 years, 32 newly diagnosed and 20 previously diagnosed with SHT who had not been treated with antihypertensive medication for 3 months or more), 48 WCHT patients (53.64 +/- 9.5 years), and 50 normotensive (NT) healthy controls (53.44 +/- 8.4 years) in our study. In addition to routine tests, PTH and vitamin D levels were measured. RESULTS: Serum PTH levels were significantly higher in SHT patients not taking antihypertensive medications than in WCHT patients and NT controls (p = 0.004). Although PTH levels were higher in WCHT than in NT groups, the difference was not statistically significant. In SHT patients, PTH levels showed a positive correlation with office systolic (r = 0.363, p = 0.008), office diastolic (r = 0.282, p = 0.038), home systolic (r = 0.390, p = 0.004), and home diastolic blood pressures (r = 0.397, p = 0.003). Serum vitamin D levels were similar in SHT, WCHT and NT groups. Vitamin D levels were not associated with blood pressures in the entire study group. Furthermore, no significant relation was found between vitamin D and PTH levels in SHT and WCHT groups. CONCLUSION: PTH levels are significantly higher in untreated SHT patients than WCHT patients and NT subjects. However, vitamin D levels are similar in SHT, WCHT and NT groups. There is a significant association between PTH levels and blood pressures suggesting PTH has a role in increase of blood pressure in SHT. PMID- 29176785 TI - Association between polymorphisms of heat-shock protein 70 genes and noise induced hearing loss: A meta-analysis. AB - BACKGROUND: Recent studies have evaluated the associations between polymorphisms of the heat-shock protein 70 (HSP70) encoding genes and noise-induced hearing loss (NIHL). However, the conclusions of these studies are conflicting. The objective of this meta-analysis was to clarify the association between all known polymorphisms of HSP70 genetic loci and susceptibility to NIHL, based on existing reports. METHODS: We conducted a meta-analysis of the association between Hsp70 polymorphisms (rs1043618, rs1061581, rs2075800, rs2227956, and rs2763979) and NIHL risk in both Chinese and Caucasian males. All statistical analysis was done with was conducted using the "meta" package (version 4.6-0) of R version 3.3.2 and RStudio version 1.0.44. Online databases were searched for eligible case control studies on February 13, 2017. The odds ratio (OR), 95% confidence interval (CI), and P value were calculated using Mantel-Haenszel statistics under a random- or fixed-effect model. RESULTS: A total of five studies, reported via four articles from online databases, were included in our meta-analysis. For rs1061581 (from three studies), a significant association was detected in the allele model, homozygote model, and dominant model (G versus A: OR (95% CI) = 1.32(1.05-1.67), GG versus AA: OR (95% CI) = 1.93(1.1-3.36), GG + AG versus AA: OR (95% CI) = 1.45(1.05-2.02)), but not in the heterozygote model or the recessive model. For rs1043618 (from five studies), rs2075800 (from two studies), rs2227956 (from four studies), rs2763979 (from two studies), no significant association was found for any genetic model. After subgroup analyses by ethnicity, significant associations were observed for the allele model, heterozygote model, and dominant model for rs1061581 and any genetic model for rs2227956 in Caucasians. CONCLUSIONS: The rs1043618, rs2075800, and rs2763979 polymorphisms were not found to be associated with susceptibility to NIHL; however, the rs1061581 and rs2227956 polymorphisms were significantly associated with NIHL in Caucasian males. PMID- 29176784 TI - PRM1 and KAR5 function in cell-cell fusion and karyogamy to drive distinct bisexual and unisexual cycles in the Cryptococcus pathogenic species complex. AB - Sexual reproduction is critical for successful evolution of eukaryotic organisms in adaptation to changing environments. In the opportunistic human fungal pathogens, the Cryptococcus pathogenic species complex, C. neoformans primarily undergoes bisexual reproduction, while C. deneoformans undergoes both unisexual and bisexual reproduction. During both unisexual and bisexual cycles, a common set of genetic circuits regulates a yeast-to-hyphal morphological transition, that produces either monokaryotic or dikaryotic hyphae. As such, both the unisexual and bisexual cycles can generate genotypic and phenotypic diversity de novo. Despite the similarities between these two cycles, genetic and morphological differences exist, such as the absence of an opposite mating-type partner and monokaryotic instead of dikaryotic hyphae during C. deneoformans unisexual cycle. To better understand the similarities and differences between these modes of sexual reproduction, we focused on two cellular processes involved in sexual reproduction: cell-cell fusion and karyogamy. We identified orthologs of the plasma membrane fusion protein Prm1 and the nuclear membrane fusion protein Kar5 in both Cryptococcus species, and demonstrated their conserved roles in cell fusion and karyogamy during C. deneoformans alpha-alpha unisexual reproduction and C. deneoformans and C. neoformans a-alpha bisexual reproduction. Notably, karyogamy occurs inside the basidum during bisexual reproduction in C. neoformans, but often occurs earlier following cell fusion during bisexual reproduction in C. deneoformans. Characterization of these two genes also showed that cell fusion is dispensable for solo unisexual reproduction in C. deneoformans. The blastospores produced along hyphae during C. deneoformans unisexual reproduction are diploid, suggesting that diploidization occurs early during hyphal development, possibly through either an endoreplication pathway or cell fusion-independent karyogamy events. Taken together, our findings suggest distinct mating mechanisms for unisexual and bisexual reproduction in Cryptococcus, exemplifying distinct evolutionary trajectories within this pathogenic species complex. PMID- 29176786 TI - In vivo imaging of palisades of Vogt in dry eye versus normal subjects using en face spectral-domain optical coherence tomography. AB - PURPOSE: To evaluate a possible clinical application of spectral-domain optical coherence tomography (SD-OCT) using en-face module for the imaging of the corneoscleral limbus in normal subjects and dry eye patients. PATIENTS AND METHODS: Seventy-six subjects were included in this study. Seventy eyes of 35 consecutive patients with dry eye disease and 82 eyes of 41 healthy control subjects were investigated. All subjects were examined with the Avanti RTVue(r) anterior segment OCT. En-face OCT images of the corneoscleral limbus were acquired in four quadrants (inferior, superior, nasal and temporal) and then were analyzed semi-quantitatively according to whether or not palisades of Vogt (POV) were visible. En-face OCT images were then compared to in vivo confocal microscopy (IVCM) in eleven eyes of 7 healthy and dry eye patients. RESULTS: En face SD-OCT showed POV as a radially oriented network, located in superficial corneoscleral limbus, with a good correlation with IVCM features. It provided an easy and reproducible identification of POV without any special preparation or any direct contact, with a grading scale from 0 (no visualization) to 3 (high visualization). The POV were found predominantly in superior (P<0.001) and inferior (P<0.001) quadrants when compared to the nasal and temporal quadrants for all subjects examined. The visibility score decreased with age (P<0.001) and was lower in dry eye patients (P<0.01). In addition, the score decreased in accordance with the severity of dry eye disease (P<0.001). CONCLUSION: En-face SD OCT is a non-contact imaging technique that can be used to evaluate the POV, thus providing valuable information about differences in the limbal anatomy of dry eye patients as compared to healthy patients. PMID- 29176787 TI - Vaccine-elicited memory CD4+ T cell expansion is impaired in the lungs during tuberculosis. AB - Immunological memory is the key biological process that makes vaccines possible. Although tuberculosis vaccines elicit protective immunity in animals, few provide durable protection. To understand why protection is transient, we evaluated the ability of memory CD4+ T cells to expand, differentiate, and control Mycobacterium tuberculosis. Both naive and memory CD4+ T cells initially proliferated exponentially, and the accumulation of memory T cells in the lung correlated with early bacterial control. However, later during infection, memory CD4+ T cell proliferation was curtailed and no protection was observed. We show that memory CD4+ T cells are first activated in the LN and their recruitment to the lung attenuates bacterial growth. However, their interaction with Mtb infected macrophages does not promote continued proliferation. We conclude that a lack of sustained expansion by memory-derived T cells in the lung limits the durability of their protection, linking their slower expansion with transient protection in vaccinated mice. PMID- 29176788 TI - Preservation of three-dimensional spatial structure in the gut microbiome. AB - Preservation of three-dimensional structure in the gut is necessary in order to analyze the spatial organization of the gut microbiota and gut luminal contents. In this study, we evaluated preparation methods for mouse gut with the goal of preserving micron-scale spatial structure while performing fluorescence imaging assays. Our evaluation of embedding methods showed that commonly used media such as Tissue-Tek Optimal Cutting Temperature (OCT) compound, paraffin, and polyester waxes resulted in redistribution of luminal contents. By contrast, a hydrophilic methacrylate resin, Technovit H8100, preserved three-dimensional organization. Our mouse intestinal preparation protocol optimized using the Technovit H8100 embedding method was compatible with microbial fluorescence in situ hybridization (FISH) and other labeling techniques, including immunostaining and staining with both wheat germ agglutinin (WGA) and 4', 6-diamidino-2-phenylindole (DAPI). Mucus could be visualized whether the sample was fixed with paraformaldehyde (PFA) or with Carnoy's fixative. The protocol optimized in this study enabled simultaneous visualization of micron-scale spatial patterns formed by microbial cells in the mouse intestines along with biogeographical landmarks such as host-derived mucus and food particles. PMID- 29176789 TI - Promising new vaccine candidates against Campylobacter in broilers. AB - Campylobacter is the leading cause of human bacterial gastroenteritis in the European Union. Birds represent the main reservoir of the bacteria, and human campylobacteriosis mainly occurs after consuming and/or handling poultry meat. Reducing avian intestinal Campylobacter loads should impact the incidence of human diseases. At the primary production level, several measures have been identified to reach this goal, including vaccination of poultry. Despite many studies, however, no efficient vaccine is currently available. We have recently identified new vaccine candidates using the reverse vaccinology strategy. This study assessed the in vivo immune and protective potential of six newly identified vaccine antigens. Among the candidates tested on Ross broiler chickens, four (YP_001000437.1, YP_001000562.1, YP_999817.1, and YP_999838.1) significantly reduced cecal Campylobacter loads by between 2 and 4.2 log10 CFU/g, with the concomitant development of a specific humoral immune response. In a second trial, cecal load reductions results were not statistically confirmed despite the induction of a strong immune response. These vaccine candidates need to be further investigated since they present promising features. PMID- 29176790 TI - Attention-deficit/hyperactivity disorder associated with KChIP1 rs1541665 in Kv channels accessory proteins. AB - Attention-deficit/hyperactivity disorder (ADHD) is an early onset childhood neurodevelopmental disorder with high heritability. A number of genetic risk factors and environment factors have been implicated in the pathogenesis of ADHD. Genes encoding for subtypes of voltage-dependent K channels (Kv) and accessory proteins to these channels have been identified in genome-wide association studies (GWAS) of ADHD. We conducted a two-stage case-control study to investigate the associations between five key genes (KChIP4, KChIP1, DPP10, FHIT, and KCNC1) and the risk of developing ADHD. In the discovery stage comprising 256 cases and 372 controls, KChIP1 rs1541665 and FHIT rs3772475 were identified; they were further genotyped in the validation stage containing 328cases and 431 controls.KChIP1 rs1541665 showed significant association with a risk of ADHD at both stages, with CC vs TT odds ratio (OR) = 1.961, 95% confidence interval (CI) = 1.366-2.497, in combined analyses (P-FDR = 0.007). Moreover, we also found rs1541665 involvement in ADHD-I subtype (OR (95% CI) = 2.341(1.713, 3.282), and Hyperactive index score (P = 0.005) in combined samples.Intriguingly, gene environmental interactions analysis consistently revealed the potential interactionsof rs1541665 collaboratingwith maternal stress pregnancy (Pmul = 0.021) and blood lead (Padd = 0.017) to modify ADHD risk. In conclusion, the current study provides evidence that genetic variants of Kv accessory proteins may contribute to the susceptibility of ADHD.Further studies with different ethnicitiesare warranted to produce definitive conclusions. PMID- 29176791 TI - The importance of thinking beyond the water-supply in cholera epidemics: A historical urban case-study. AB - BACKGROUND: Planning interventions to respond to cholera epidemics requires an understanding of the major transmission routes. Interrupting short-cycle (household, foodborne) transmission may require different approaches as compared long-cycle (environmentally-mediated/waterborne) transmission. However, differentiating the relative contribution of short- and long-cycle routes has remained difficult, and most cholera outbreak control efforts focus on interrupting long-cycle transmission. Here we use high-resolution epidemiological and municipal infrastructure data from a cholera outbreak in 1853 Copenhagen to explore the relative contribution of short- and long-cycle transmission routes during a major urban epidemic. METHODOLOGY/PRINCIPAL FINDINGS: We fit a spatially explicit time-series meta-population model to 6,552 physician-reported cholera cases from Copenhagen in 1853. We estimated the contribution of long-cycle waterborne transmission between neighborhoods using historical municipal water infrastructure data, fitting the force of infection from hydraulic flow, then comparing model performance. We found the epidemic was characterized by considerable transmission heterogeneity. Some neighborhoods acted as localized transmission hotspots, while other neighborhoods were less affected or important in driving the epidemic. We found little evidence to support long-cycle transmission between hydrologically-connected neighborhoods. Collectively, these findings suggest short-cycle transmission was significant. CONCLUSIONS/SIGNIFICANCE: Spatially targeted cholera interventions, such as reactive vaccination or sanitation/hygiene campaigns in hotspot neighborhoods, would likely have been more effective in this epidemic than control measures aimed at interrupting long-cycle transmission, such as improving municipal water quality. We recommend public health planners consider programs aimed at interrupting short-cycle transmission as essential tools in the cholera control arsenal. PMID- 29176792 TI - Genome-wide DNase hypersensitivity, and occupancy of RUNX2 and CTCF reveal a highly dynamic gene regulome during MC3T3 pre-osteoblast differentiation. AB - The ability to discover regulatory sequences that control bone-related genes during development has been greatly improved by massively parallel sequencing methodologies. To expand our understanding of cis-regulatory regions critical to the control of gene expression during osteoblastogenesis, we probed the presence of open chromatin states across the osteoblast genome using global DNase hypersensitivity (DHS) mapping. Our profiling of MC3T3 mouse pre-osteoblasts during differentiation has identified more than 224,000 unique DHS sites. Approximately 65% of these sites are dynamic during temporal stages of osteoblastogenesis, and a majority of them are located within non-promoter (intergenic and intronic) regions. Nearly half of all DHS sites (both constitutive and dynamic) overlap binding events of the bone-essential RUNX2 and/or the chromatin-related CTCF transcription factors. This finding reinforces the role of these regulatory proteins as essential components of the bone gene regulome. We observe a reduction in chromatin accessibility throughout the genome between pre-osteoblast and early osteoblasts. Our analysis also defined a class of differentially expressed genes that harbor DHS peaks centered within 1 kb downstream of transcriptional end sites (TES). These DHSs at the 3'-flanks of genes exhibit dynamic changes during differentiation that may impact regulation of the osteoblast genome. Taken together, the distribution of DHS regions within non-promoter locations harboring osteoblast and chromatin related transcription factor binding motifs, reflect novel cis-regulatory requirements to support temporal gene expression in differentiating osteoblasts. PMID- 29176793 TI - Menstrual cycle characteristics of young females with occult primary ovarian insufficiency at initial diagnosis and one-year follow-up with serum amh level and antral follicle count. AB - Occult primary ovarian insufficiency (also known as incipient ovarian failure or diminished ovarian reserve) is defined as serum AMH level <=1.1ng/mL in women under age 30. Limited data is available regarding the prevalence of occult POI, the preceding menstrual characteristics and its natural course in otherwise healthy young females. We aimed in this prospective observational study to determine the prevalence of occult POI in young females (< age 30) screened with serum AMH measurement; and analyze the patterns of change in their menstruation at initial assessment and one-year follow-up in relation to the changes in ovarian reserve quantitatively assessed with AMH and AFC. 963 young female college students under age 30 voluntarily participated in this study. 43 of them (4.4%) were diagnosed with occult POI as their AMH levels were <= 1.1ng/mL. Thirty-eight (83.4%) of them have regular cycles and denied any menstrual irregularity in the last 12 months. This rate was not statistically different from 7.3% of those with AMH>1.1ng/mL who reported at least one abnormal menstrual cycle in the last year (p = 0.36). Cycle length was significantly shorter in females with AMH <= 1.1ng/mL compared to those with AMH>1.1ng/mL (25.1+/-3.2 vs. 31.2+/-2.8 respectively, p<0.001). Karyotype, FMR-1 mutation analyses and auto antibody screening returned normal in all. At one-year follow-up AMH, AFC and mean cycle length were further reduced compared to their values at initial assessment. Now, a greater proportion of the participants with occult POI were menstruating regularly at every 21 days compared to the initial evaluation one year ago (39.5% vs. 13.9% respectively, p = 0.013). Twenty-five underwent oocyte cryopreservation. These findings underscore the importance of screening young females with AMH for possible occult POI. It also emphasizes that young females with critically diminished ovarian reserve may continue to menstruate regularly without any characteristic menstrual abnormality other than shortening of cycle length. PMID- 29176794 TI - Capillary refill time during fluid resuscitation in patients with sepsis-related hyperlactatemia at the emergency department is related to mortality. AB - INTRODUCTION: Acute circulatory dysfunction in patients with sepsis can evolve rapidly into a progressive stage associated with high mortality. Early recognition and adequate resuscitation could improve outcome. However, since the spectrum of clinical presentation is quite variable, signs of hypoperfusion are frequently unrecognized in patients just admitted to the emergency department (ED). Hyperlactatemia is considered a key parameter to disclose tissue hypoxia but it is not universally available and getting timely results can be challenging in low resource settings. In addition, non-hypoxic sources can be involved in hyperlactatemia, and a misinterpretation could lead to over-resuscitation in an unknown number of cases. Capillary refill time (CRT) is a marker of peripheral perfusion that worsens during circulatory failure. An abnormal CRT in septic shock patients after ICU-based resuscitation has been associated with poor outcome. The aim of this study was to determine the prevalence of abnormal CRT in patients with sepsis-related hyperlactatemia in the early phase after ED admission, and its relationship with outcome. METHODS: We performed a prospective observational study. Septic patients with hyperlactemia at ED admission subjected to an initial fluid resuscitation (FR) were included. CRT and other parameters were assessed before and after FR. CRT-normal or CRT-abnormal subgroups were defined according to the status of CRT following initial FR, and major outcomes were registered. RESULTS: Ninety-five hyperlactatemic septic patients were included. Thirty-one percent had abnormal CRT at ED arrival. After FR, 87 patients exhibited normal CRT, and 8 an abnormal one. Patients with abnormal CRT had an increased risk of adverse outcomes (88% vs. 20% p<0.001; RR 4.4 [2.7 7.4]), and hospital mortality (63% vs. 9% p<0.001; RR 6.7 [2.9-16]) as compared to those with normal CRT after FR. Specifically, CRT-normal patients required less frequently mechanical ventilation, renal replacement therapy, and ICU admission, and exhibited a lower hospital mortality. CONCLUSIONS: Hyperlactatemic sepsis patients with abnormal CRT after initial fluid resuscitation exhibit higher mortality and worse clinical outcomes than patients with normal CRT. PMID- 29176795 TI - The full transcription map of mouse papillomavirus type 1 (MmuPV1) in mouse wart tissues. AB - Mouse papillomavirus type 1 (MmuPV1) provides, for the first time, the opportunity to study infection and pathogenesis of papillomaviruses in the context of laboratory mice. In this report, we define the transcriptome of MmuPV1 genome present in papillomas arising in experimentally infected mice using a combination of RNA-seq, PacBio Iso-seq, 5' RACE, 3' RACE, primer-walking RT-PCR, RNase protection, Northern blot and in situ hybridization analyses. We demonstrate that the MmuPV1 genome is transcribed unidirectionally from five major promoters (P) or transcription start sites (TSS) and polyadenylates its transcripts at two major polyadenylation (pA) sites. We designate the P7503, P360 and P859 as "early" promoters because they give rise to transcripts mostly utilizing the polyadenylation signal at nt 3844 and therefore can only encode early genes, and P7107 and P533 as "late" promoters because they give rise to transcripts utilizing polyadenylation signals at either nt 3844 or nt 7047, the latter being able to encode late, capsid proteins. MmuPV1 genome contains five splice donor sites and three acceptor sites that produce thirty-six RNA isoforms deduced to express seven predicted early gene products (E6, E7, E1, E1^M1, E1^M2, E2 and E8^E2) and three predicted late gene products (E1^E4, L2 and L1). The majority of the viral early transcripts are spliced once from nt 757 to 3139, while viral late transcripts, which are predicted to encode L1, are spliced twice, first from nt 7243 to either nt 3139 (P7107) or nt 757 to 3139 (P533) and second from nt 3431 to nt 5372. Thirteen of these viral transcripts were detectable by Northern blot analysis, with the P533-derived late E1^E4 transcripts being the most abundant. The late transcripts could be detected in highly differentiated keratinocytes of MmuPV1-infected tissues as early as ten days after MmuPV1 inoculation and correlated with detection of L1 protein and viral DNA amplification. In mature warts, detection of L1 was also found in more poorly differentiated cells, as previously reported. Subclinical infections were also observed. The comprehensive transcription map of MmuPV1 generated in this study provides further evidence that MmuPV1 is similar to high-risk cutaneous beta human papillomaviruses. The knowledge revealed will facilitate the use of MmuPV1 as an animal virus model for understanding of human papillomavirus gene expression, pathogenesis and immunology. PMID- 29176796 TI - Revisiting primary neural leprosy: Clinical, serological, molecular, and neurophysiological aspects. AB - BACKGROUND: Leprosy neuropathy is considered the most common peripheral neuropathy of infectious etiology worldwide, representing a public health problem. Clinical diagnosis of primary neural leprosy (PNL) is challenging, since no skin lesions are found and the slit skin smear bacilloscopy is negative. However, there are still controversial concepts regarding the primary-neural versus pure-neural leprosy definition, which will be explored by using multiple clinical-laboratory analyses in this study. METHODOLOGY/PRINCIPAL FINDINGS: Seventy patients diagnosed with primary neural leprosy from 2014 to 2016 underwent clinical, laboratorial and neurophysiological evaluation. All patients presented an asymmetric neural impairment, with nerve thickening in 58.6%. Electroneuromyography showed a pattern of mononeuropathy in 51.4%. Positivity for ELISA anti-PGL1 was 52.9%, while the qPCR of slit skin smear was 78.6%. The qPCR of nerve biopsies was positive in 60.8%. Patients with multiple mononeuropathy patterns showed lower levels of anti-PGL-1 (p = 0.0006), and higher frequency of neural thickening (p = 0.0008) and sensory symptoms (p = 0.01) than those with mononeuropathy. CONCLUSIONS/SIGNIFICANCE: PNL is not a synonym of pure neural leprosy, as this condition may include a generalized immune response and also a skin involvement, documented by molecular findings. Immunological, molecular, and neurophysiological tools must be implemented for diagnosing primary neural leprosy to achieve effective treatment and reduction of its resultant disabilities that still represent a public health problem in several developing nations. Finally, we propose a algorithm and recommendations for the diagnosis of primary neural leprosy based on the combination of the three clinical laboratorial tools. PMID- 29176797 TI - Cytokines, hepatic cell profiling and cell interactions during bone marrow cell therapy for liver fibrosis in cholestatic mice. AB - Bone marrow cells (BMC) migrate to the injured liver after transplantation, contributing to regeneration through multiple pathways, but mechanisms involved are unclear. This work aimed to study BMC migration, characterize cytokine profile, cell populations and proliferation in mice with liver fibrosis transplanted with GFP+ BMC. Confocal microscopy analysis showed GFP+ BMC near regions expressing HGF and SDF-1 in the fibrotic liver. Impaired liver cell proliferation in fibrotic groups was restored after BMC transplantation. Regarding total cell populations, there was a significant reduction in CD68+ cells and increased Ly6G+ cells in transplanted fibrotic group. BMC contributed to the total populations of CD144, CD11b and Ly6G cells in the fibrotic liver, related to an increment of anti-fibrotic cytokines (IL-10, IL-13, IFN-gamma and HGF) and reduction of pro-inflammatory cytokines (IL-17A and IL-6). Therefore, HGF and SDF-1 may represent important chemoattractants for transplanted BMC in the injured liver, where these cells can give rise to populations of extrahepatic macrophages, neutrophils and endothelial progenitor cells that can interact synergistically with other liver cells towards the modulation of an anti-fibrotic cytokine profile promoting the onset of liver regeneration. PMID- 29176798 TI - The scavenging chemokine receptor ACKR2 has a significant impact on acute mortality rate and early lesion development after traumatic brain injury. AB - The atypical chemokine receptor ACKR2 promotes resolution of acute inflammation by operating as a scavenger receptor for inflammatory CC chemokines in several experimental models of inflammatory disorders, however its role in the brain remains unclear. Based on our previous reports of increased expression of inflammatory chemokines and their corresponding receptors following traumatic brain injury (TBI), we hypothesised that ACKR2 modulates neuroinflammation following brain trauma and that its deletion exacerbates cellular inflammation and chemokine production. We demonstrate increased CCL2 and ACKR2 mRNA expression in post-mortem human brain, whereby ACKR2 mRNA levels correlated with later times post-TBI. This data is consistent with the transient upregulation of ACKR2 observed in mouse brain after closed head injury (CHI). As compared to WT animals, ACKR2-/- mice showed a higher mortality rate after CHI, while the neurological outcome in surviving mice was similar. At day 1 post-injury, ACKR2-/ mice displayed aggravated lesion volume and no differences in CCL2 expression and macrophage recruitment relative to WT mice. Reciprocal regulation of ACKR2 and CCL2 expression was explored in cultured astrocytes, which are recognized as the major source of CCL2 and also express ACKR2. ACKR2 mRNA increased as early as 2 hours after an inflammatory challenge in WT astrocytes. As expected, CCL2 expression also dramatically increased at 4 hours in WT astrocytes but was significantly lower in ACKR2-/- astrocytes, possibly indicating a co-regulation of CCL2 and ACKR2 in these cells. Conversely, in vivo, CCL2 mRNA/protein levels were increased similarly in ACKR2-/- and WT brains at 4 and 12 hours after CHI, in line with the lack of differences in cerebral macrophage recruitment and neurological recovery. In conclusion, ACKR2 is induced after TBI and has a significant impact on mortality and lesion development acutely following CHI, while its role in chemokine expression, macrophage activation, brain pathology, and neurological recovery at later time-points is minor. Concordant to evidence in multiple sclerosis experimental models, our data corroborate a distinct role for ACKR2 in cerebral inflammatory processes compared to its reported functions in peripheral tissues. PMID- 29176799 TI - Dry eye, sleep quality, and mood status in glaucoma patients receiving prostaglandin monotherapy were comparable with those in non-glaucoma subjects. AB - PURPOSE: Prior studies suggested that glaucoma patients suffer worse dry eye and mood and sleep disorders than non-glaucoma subjects. Prostaglandin analogues are first-line therapy for glaucoma, inducing few instillation problems and sufficient pressure-reduction effects. This study compared dry eye, sleep quality, and mood status between glaucoma patients receiving prostaglandin monotherapy and non-glaucoma subjects. METHODS: This cross-sectional study evaluated 1520 patients (579 males and 941 females) for glaucoma status and dry eye-related symptoms (dryness, eye fatigue, photophobia, pain, blurring) and signs (Schirmer test, tear break-up time, corneal staining scores). Of the total cohort, 93 patients were also evaluated by Pittsburgh sleep quality index (PSQI) and hospital anxiety and depression score (HADS). Inclusion criteria were consecutive patients >= 51 years of age and best-corrected visual acuity >= 20/25. Glaucoma patients included those treated with prostaglandin or a fixed combination including prostaglandin. Exclusion criteria were history of ocular surgery within one month. Data were analyzed using the chi-square or Mann-Whitney U tests, at 5% significance. RESULTS: There were no significant differences in dry eye-related signs and symptoms between the control (n = 1431, mean age of 66.9 years) and glaucoma groups (n = 89, 67.9 years). The psychiatric sub analysis of the control (n = 61, 66.2 years) and glaucoma groups (n = 32, 67.3 years) revealed mean scores of 5.02 +/- 3.10 and 5.16 +/- 3.46 for PSQI (normal range <= 5), 9.47 +/- 5.61 and 9.42 +/- 7.36 for HADS (normal range <= 10), 4.84 +/- 3.22 and 4.71 +/- 3.45 for anxiety (normal range <= 5), and 4.63 +/- 3.05 and 4.71 +/- 4.40 for depression (normal range <= 5), respectively, without statistical significance. CONCLUSIONS: Our results were comparable between glaucoma patients on prostaglandin monotherapy and non-glaucoma subjects for dry eye-related clinical manifestations, sleep quality, and mood status. PMID- 29176800 TI - Disentangling self-management goal setting and action planning: A scoping review. AB - INTRODUCTION: The ongoing rise in the numbers of chronically ill people necessitates efforts for effective self-management. Goal setting and action planning are frequently used, as they are thought to support patients in changing their behavior. However, it remains unclear how goal setting and action planning in the context of self-management are defined in the scientific literature. This study aimed to achieve a better understanding of the various definitions used. METHODS: A scoping review was conducted, searching PubMed, Cinahl, PsychINFO and Cochrane. Inclusion and exclusion criteria were formulated to ensure the focus on goal setting/action planning and self-management. The literature was updated to December 2015; data selection and charting was done by two reviewers. A qualitative content analysis approach was used. RESULTS: Out of 9115 retrieved articles, 58 met the inclusion criteria. We created an overview of goal setting phases that were applied (preparation, formulation of goals, formulation of action plan, coping planning and follow-up). Although the phases we found are in accordance with commonly known frameworks for goal setting, it was striking that the majority of studies (n = 39, 67%) did not include all phases. We also prepared an overview of components and strategies for each goal setting phase. Interestingly, few strategies were found for the communication between patients and professionals about goals/action plans. Most studies (n = 35, 60%) focused goal setting on one single disease and on a predefined lifestyle behavior; nearly half of the articles (n = 27, 47%) reported a theoretical framework. DISCUSSION: The results might provide practical support for developers of interventions. Moreover, our results might encourage professionals to become more aware of the phases of the goal setting process and of strategies emphasizing on patient reflection. However, more research might be useful to examine strategies to facilitate communication about goals/action plans. It might also be worthwhile to develop and evaluate goal setting/action planning strategies for people with different and multiple chronic conditions. PMID- 29176801 TI - Increasing vaccine production using pulsed ultrasound waves. AB - Vaccination is a safe and effective approach to prevent deadly diseases. To increase vaccine production, we propose that a mechanical stimulation can enhance protein production. In order to prove this hypothesis, Sf9 insect cells were used to evaluate the increase in the expression of a fusion protein from hepatitis B virus (HBV S1/S2). We discovered that the ultrasound stimulation at a frequency of 1.5 MHz, intensity of 60 mW/cm2, for a duration of 10 minutes per day increased HBV S1/S2 by 27%. We further derived a model for transport through a cell membrane under the effect of ultrasound waves, tested the key assumptions of the model through a molecular dynamics simulation package, NAMD (Nanoscale Molecular Dynamics program) and utilized CHARMM force field in a steered molecular dynamics environment. The results show that ultrasound waves can increase cell permeability, which, in turn, can enhance nutrient / waste exchange thus leading to enhanced vaccine production. This finding is very meaningful in either shortening vaccine production time, or increasing the yield of proteins for use as vaccines. PMID- 29176802 TI - Assessment of automated analysis of portable oximetry as a screening test for moderate-to-severe sleep apnea in patients with chronic obstructive pulmonary disease. AB - BACKGROUND: The coexistence of obstructive sleep apnea syndrome (OSAS) and chronic obstructive pulmonary disease (COPD) leads to increased morbidity and mortality. The development of home-based screening tests is essential to expedite diagnosis. Nevertheless, there is still very limited evidence on the effectiveness of portable monitoring to diagnose OSAS in patients with pulmonary comorbidities. OBJECTIVE: To assess the influence of suffering from COPD in the performance of an oximetry-based screening test for moderate-to-severe OSAS, both in the hospital and at home. METHODS: A total of 407 patients showing moderate-to high clinical suspicion of OSAS were involved in the study. All subjects underwent (i) supervised portable oximetry simultaneously to in-hospital polysomnography (PSG) and (ii) unsupervised portable oximetry at home. A regression-based multilayer perceptron (MLP) artificial neural network (ANN) was trained to estimate the apnea-hypopnea index (AHI) from portable oximetry recordings. Two independent validation datasets were analyzed: COPD versus non COPD. RESULTS: The portable oximetry-based MLP ANN reached similar intra-class correlation coefficient (ICC) values between the estimated AHI and the actual AHI for the non-COPD and the COPD groups either in the hospital (non-COPD: 0.937, 0.909-0.956 CI95%; COPD: 0.936, 0.899-0.960 CI95%) and at home (non-COPD: 0.731, 0.631-0.808 CI95%; COPD: 0.788, 0.678-0.864 CI95%). Regarding the area under the receiver operating characteristics curve (AUC), no statistically significant differences (p >0.01) between COPD and non-COPD groups were found in both settings, particularly for severe OSAS (AHI >=30 events/h): 0.97 (0.92-0.99 CI95%) non-COPD vs. 0.98 (0.92-1.0 CI95%) COPD in the hospital, and 0.87 (0.79 0.92 CI95%) non-COPD vs. 0.86 (0.75-0.93 CI95%) COPD at home. CONCLUSION: The agreement and the diagnostic performance of the estimated AHI from automated analysis of portable oximetry were similar regardless of the presence of COPD both in-lab and at-home. Particularly, portable oximetry could be used as an abbreviated screening test for moderate-to-severe OSAS in patients with COPD. PMID- 29176803 TI - Root bark of Ulmus davidiana var. japonica restrains acute alcohol-induced hepatic steatosis onset in mice by inhibiting ROS accumulation. AB - Alcohol-induced hepatic steatosis and inflammation are key drivers of alcohol induced liver injury, mainly caused by oxidative stress. The roots bark of Ulmus davidiana var. japonica is well known for its substantial antioxidative and antitumorigenic potency. In this study, we examined whether this plant can ameliorate alcohol-induced liver injuries characterized by hepatic steatosis and inflammation through its antioxidative activity. C57BL/6J mice were treated with the root bark extract of Ulmus davidiana var. japonica (RUE; 100 mg of extract/kg bodyweight; oral gavage) and alcohol (1 g/kg of bodyweight; oral gavage) for 5 days. Markers of acute alcohol-induced hepatic steatosis were determined and putative molecular mechanisms responsible for the protection of RUE were investigated. RUE noticeably protected against alcohol-induced hepatic steatosis and inflammation. Reactive oxygen species (ROS), over-produced by alcohol, negatively orchestrated various signaling pathways involved in the lipid metabolism and inflammation. These pathways were restored through the ROS scavenging activity of RUE in the liver. In particular, the expression of lipogenic genes (e.g., SREBP-1, ACC, and FAS) and inflammatory cytokines (e.g., IL-1beta, and NF-kappaB p65) significantly decreased with RUE treatment. Conversely, the expression of fatty acid oxidation-related genes (e.g., SIRT1, AMPKalpha, and PGC1alpha) were increased in mice treated with RUE. Thus, the results indicate that RUE counteracts and thus attenuates alcoholic hepatic steatosis onset in mice, possibly by suppressing ROS-mediated steatosis and inflammation. PMID- 29176804 TI - One crisis, diverse impacts-Tissue-specificity of folate deficiency-induced circulation defects in zebrafish larvae. AB - Folate (vitamin B9) is an essential nutrient required for cell survival, proliferation, differentiation and therefore embryogenesis. Folate deficiency has been associated with many diseases, including congenital heart diseases and megaloblastic anemia, yet the mechanisms underlying these remains elusive. Here, we examine the impact of folate deficiency on the development of the circulation system using a zebrafish transgenic line which displays inducible folate deficiency. Impaired hematopoiesis includes decreased hemoglobin levels, decreased erythrocyte number, increased erythrocyte size and aberrant c-myb expression pattern were observed in folate deficient embryos. Cardiac defects, including smaller chamber size, aberrant cardiac function and cmlc2 expression pattern, were also apparent in folate deficient embryos. Characterization of intracellular folate content in folate deficiency revealed a differential fluctuation among the different folate derivatives that carry a single carbon group at different oxidation levels. Rescue attempts by folic acid and nucleotides resulted in differential responses among affected tissues, suggesting that different pathomechanisms are involved in folate deficiency-induced anomalies in a tissue-specific manner. The results of the current study provide an explanation for the inconsistent outcome observed clinically in patients suffering from folate deficiency and/or receiving folate supplementation. This study also supports the use of this model for further research on the defective cardiogenesis and hematopoiesis caused by folate deficiency. PMID- 29176805 TI - Modulation of host central carbon metabolism and in situ glucose uptake by intracellular Trypanosoma cruzi amastigotes. AB - Obligate intracellular pathogens satisfy their nutrient requirements by coupling to host metabolic processes, often modulating these pathways to facilitate access to key metabolites. Such metabolic dependencies represent potential targets for pathogen control, but remain largely uncharacterized for the intracellular protozoan parasite and causative agent of Chagas disease, Trypanosoma cruzi. Perturbations in host central carbon and energy metabolism have been reported in mammalian T. cruzi infection, with no information regarding the impact of host metabolic changes on the intracellular amastigote life stage. Here, we performed cell-based studies to elucidate the interplay between infection with intracellular T. cruzi amastigotes and host cellular energy metabolism. T. cruzi infection of non-phagocytic cells was characterized by increased glucose uptake into infected cells and increased mitochondrial respiration and mitochondrial biogenesis. While intracellular amastigote growth was unaffected by decreased host respiratory capacity, restriction of extracellular glucose impaired amastigote proliferation and sensitized parasites to further growth inhibition by 2-deoxyglucose. These observations led us to consider whether intracellular T. cruzi amastigotes utilize glucose directly as a substrate to fuel metabolism. Consistent with this prediction, isolated T. cruzi amastigotes transport extracellular glucose with kinetics similar to trypomastigotes, with subsequent metabolism as demonstrated in 13C-glucose labeling and substrate utilization assays. Metabolic labeling of T. cruzi-infected cells further demonstrated the ability of intracellular parasites to access host hexose pools in situ. These findings are consistent with a model in which intracellular T. cruzi amastigotes capitalize on the host metabolic response to parasite infection, including the increase in glucose uptake, to fuel their own metabolism and replication in the host cytosol. Our findings enrich current views regarding available carbon sources for intracellular T. cruzi amastigotes and underscore the metabolic flexibility of this pathogen, a feature predicted to underlie successful colonization of tissues with distinct metabolic profiles in the mammalian host. PMID- 29176806 TI - Phylogeography of the Central American lancehead Bothrops asper (SERPENTES: VIPERIDAE). AB - The uplift and final connection of the Central American land bridge is considered the major event that allowed biotic exchange between vertebrate lineages of northern and southern origin in the New World. However, given the complex tectonics that shaped Middle America, there is still substantial controversy over details of this geographical reconnection, and its role in determining biogeographic patterns in the region. Here, we examine the phylogeography of Bothrops asper, a widely distributed pitviper in Middle America and northwestern South America, in an attempt to evaluate how the final Isthmian uplift and other biogeographical boundaries in the region influenced genealogical lineage divergence in this species. We examined sequence data from two mitochondrial genes (MT-CYB and MT-ND4) from 111 specimens of B. asper, representing 70 localities throughout the species' distribution. We reconstructed phylogeographic patterns using maximum likelihood and Bayesian methods and estimated divergence time using the Bayesian relaxed clock method. Within the nominal species, an early split led to two divergent lineages of B. asper: one includes five phylogroups distributed in Caribbean Middle America and southwestern Ecuador, and the other comprises five other groups scattered in the Pacific slope of Isthmian Central America and northwestern South America. Our results provide evidence of a complex transition that involves at least two dispersal events into Middle America during the final closure of the Isthmus. PMID- 29176807 TI - Adolescent motherhood in Bangladesh: Trends and determinants. AB - BACKGROUND: While studies on fertility and contraceptives issues are available, until recently adolescent motherhood has not received enough attention among policy makers in understanding adolescent motherhood in Bangladesh. We aimed to examine the trends and determinants of adolescent motherhood among women aged 15 49 years. METHODS: For trend analysis we used all the 7 waves of Bangladesh Demographic and Health Survey (BDHS, 1993-2014) data but for multivariate analysis 4 waves of BDHS (2004-2014). Two separate analyses were carried out on ever married women aged 15-49: (1) teenage girls aged 15-19 and (2) adult women aged 20 and above. RESULTS: The prevalence of adolescent motherhood had declined to a slower pace from 1993 to2014 (from 33.0% to 30.8%). Lower spousal age gap and higher education were found to be associated with lower likelihood of adolescent motherhood both among teenage girls [OR 0.447 (0.374-0.533)] and adult women [OR 0.451 (0.420-0.484)]. Teenage girls in the poorest wealth quintile [OR 1.712 [1.350-2.173] were more likely to experience adolescent motherhood than the richest wealth quintile. Teenage girls who had no education were found to have 2.76 times higher odds of adolescent motherhood than their counterparts who had higher than secondary education. Concerning the time effect, the odds of adolescent motherhood among adult women was found to decline overtime. CONCLUSIONS: Despite substantial decrease in total fertility rate in Bangladesh adolescent motherhood is still highly prevalent though declining from 1993 to 2014. Social policies including those addressing poverty, ensuring greater emphasis on education for women; and adolescent mothers in rural areas are needed. PMID- 29176808 TI - Initial-state-dependent, robust, transient neural dynamics encode conscious visual perception. AB - Recent research has identified late-latency, long-lasting neural activity as a robust correlate of conscious perception. Yet, the dynamical nature of this activity is poorly understood, and the mechanisms governing its presence or absence and the associated conscious perception remain elusive. We applied dynamic-pattern analysis to whole-brain slow (< 5 Hz) cortical dynamics recorded by magnetoencephalography (MEG) in human subjects performing a threshold-level visual perception task. Up to 1 second before stimulus onset, brain activity pattern across widespread cortices significantly predicted whether a threshold level visual stimulus was later consciously perceived. This initial state of brain activity interacts nonlinearly with stimulus input to shape the evolving cortical activity trajectory, with seen and unseen trials following well separated trajectories. We observed that cortical activity trajectories during conscious perception are fast evolving and robust to small variations in the initial state. In addition, spontaneous brain activity pattern prior to stimulus onset also influences unconscious perceptual making in unseen trials. Together, these results suggest that brain dynamics underlying conscious visual perception belongs to the class of initial-state-dependent, robust, transient neural dynamics. PMID- 29176809 TI - Association between social support and health-related quality of life among Chinese seafarers: A cross-sectional study. AB - BACKGROUND: Seafarers have reported impaired health and health-related quality of life (HRQOL). Social support might increase HRQOL, but little is known about this association among Chinese seafarers. The aim of this study was to describe social support and explore its association with HRQOL among Chinese seafarers. METHODS: A cross-sectional survey was conducted in the ports of Nantong and Rugao, China, from April to December 2013. A total of 917 Chinese seafarers were interviewed on social support, mental distress, perceived occupational stress, and HRQOL using the following self-administered questionnaires: The Social Support Rating Scale, Self-rating Depression Scale, Occupational Stress Questionnaire, and the World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire. Hierarchical linear regression modelling was used to analyze the association between seafarers' subjective level of social support and their HRQOL. RESULTS: Of the 917 male Chinese seafarers included in the study, 40.7% perceived high levels of social support, and 39.1% were highly satisfied with their overall quality of life (QOL). Hierarchical regression analysis showed significant associations between level of social support and all health dimensions in the WHOQOL-BREF, even after adjusting for depressive symptoms, occupational stress, occupational activities, sleep duration, and other relevant covariates. Compared with the medium or low level social support group, seafarers with a high level of social support had better QOL scores in the general facet health and QOL (beta = 2.43, p<0.05), and the physical health (beta = 3.23, p<0.001), psychological health (beta = 5.56, p<0.001), social relation (beta = 6.07, p<0.001), and environment domains (beta = 4.27, p<0.001). In addition, depression, occupational stress, occupational activities, and sleep duration were found to be determinants of seafarers' HRQOL. CONCLUSIONS: Chinese seafarers have poorer HRQOL than the general population, but social support has a significant positive effect on their HRQOL. Efforts to improve social support should be undertaken. PMID- 29176811 TI - Dietary partitioning of Australia's two marsupial hypercarnivores, the Tasmanian devil and the spotted-tailed quoll, across their shared distributional range. AB - Australia's native marsupial fauna has just two primarily flesh-eating 'hypercarnivores', the Tasmanian devil (Sarcophilus harrisii) and the spotted tailed quoll (Dasyurus maculatus) which coexist only on the island of Tasmania. Devil populations are currently declining due to a fatal transmissible cancer. Our aim was to analyse the diet of both species across their range in Tasmania, as a basis for understanding how devil decline might affect the abundance and distribution of quolls through release from competition. We used faecal analysis to describe diets of one or both species at 13 sites across Tasmania. We compared diet composition and breadth between the two species, and tested for geographic patterns in diets related to rainfall and devil population decline. Dietary items were classified into 6 broad categories: large mammals (>= 7.0kg), medium-sized mammals (0.5-6.9kg), small mammals (< 0.5kg), birds, reptiles and invertebrates. Diet overlap based on prey-size category was high. Quoll diets were broader than devils at all but one site. Devils consumed more large and medium-sized mammals and quolls more small mammals, reptiles and invertebrates. Medium-sized mammals (mainly Tasmanian pademelon Thylogale billardierii), followed by large mammals (mainly Bennett's wallaby Macropus rufogriseus) and birds, were the most important prey groups for both species. Diet composition varied across sites, suggesting that both species are flexible and opportunistic foragers, but was not related to rainfall for devils. Quolls included more large mammals but fewer small mammals and invertebrates in their diet in the eastern drier parts of Tasmania where devils have declined. This suggests that a competitive release of quolls may have occurred and the substantial decline of devils has provided more food in the large-mammal category for quolls, perhaps as increased scavenging opportunities. The high diet overlap suggests that if resources become limited in areas of high devil density, interspecific competition could occur. PMID- 29176810 TI - Flip/flop mating-type switching in the methylotrophic yeast Ogataea polymorpha is regulated by an Efg1-Rme1-Ste12 pathway. AB - In haploid cells of Ogataea (Hansenula) polymorpha an environmental signal, nitrogen starvation, induces a reversible change in the structure of a chromosome. This process, mating-type switching, inverts a 19-kb DNA region to place either MATa or MATalpha genes under centromeric repression of transcription, depending on the orientation of the region. Here, we investigated the genetic pathway that controls switching. We characterized the transcriptomes of haploid and diploid O. polymorpha by RNAseq in rich and nitrogen-deficient media, and found that there are no constitutively a-specific or alpha-specific genes other than the MAT genes themselves. We mapped a switching defect in a sibling species (O. parapolymorpha strain DL-1) by interspecies bulk segregant analysis to a frameshift in the transcription factor EFG1, which in Candida albicans regulates filamentous growth and white-opaque switching. Gene knockout, overexpression and ChIPseq experiments show that EFG1 regulates RME1, which in turn regulates STE12, to achieve mating-type switching. All three genes are necessary both for switching and for mating. Overexpression of RME1 or STE12 is sufficient to induce switching without a nitrogen depletion signal. The homologous recombination genes RAD51 and RAD17 are also necessary for switching. The pathway controlling switching in O. polymorpha shares no components with the regulation of HO in S. cerevisiae, which does not involve any environmental signal, but it shares some components with mating-type switching in Kluyveromyces lactis and with white-opaque phenotypic switching in C. albicans. PMID- 29176812 TI - Generation Y and surgical residency - Passing the baton or the end of the world as we know it? Results from a survey among medical students in Germany. AB - INTRODUCTION: The current student generation have their own expectations toward professional life and pay particular attention to their work-life balance. Less interest in work-intensive specialties leads to a shortage of skilled candidates especially in surgery. In order to motivate students into a surgical residency, new priorities become important. A deeper understanding of the underlying arguments and students' expectations towards a surgical training are necessary to counteract a future shortage of specialized surgeons. METHODS: We conducted an internet-based survey among medical students at two representative German university hospitals to gain more information about the underlying mechanisms that lead to opting for and against a surgical career. We particularly paid attention to gender differences and differences between students of different academic years. RESULTS: A total of 1098 students participated in the survey. Sixty-four percent were female. The majority of the students were of the opinion that surgery is an interesting and meaningful profession. In contrast, when it comes to their own career choice, most students (89% female and 81% male) are not willing to choose a surgical specialty. While students are certainly willing to spend a large amount of time on their professional lives, at the same time they demand planning reliability and a sufficient work-life balance. Flexibility in working hours and an existing childcare program were identified as predominant factors for all students and in particular for female students. The same applies to a respectful conversional tone and appreciation of the individual work. Factors like prestige and salary were less relevant than "self-fulfillment" in terms of respectful interaction and balancing their working and private lives. There was significant difference in female and male students as female students have clearer ideas concerning career planning but at the same time are less self confident than their male colleagues. Moreover, there was a significant difference between junior and senior students regarding career planning with a shift to less work-intensive specialties and especially away from a surgical residency in older students. Adjustments to working hours models, working environment, clinical curriculum and a respectful interaction are factors that might increase the willingness of young students to choose a surgical career. PMID- 29176813 TI - In situ organism-sediment interactions: Bioturbation and biogeochemistry in a highly depositional estuary. AB - Organic matter (OM) production and degradation is important in coastal estuaries, and OM fate is strongly influenced by the coupled interactions of bioturbation and biogeochemistry. From April to September 2013 sediment cores and a benthic observing system, Wormcam, were used to investigate the in situ relationship of biogeochemistry and macrofauna bioturbation in Cape Lookout Bight North Carolina. Wormcam imagery provided a vivid depiction of macrofauna functioning in an environment not previously observed, and affirmed the importance of fine-scale temporal observations of the benthic environment in situ. Observation of macrofauna presence and bioturbation during the summer contradicted previous studies that found this area to be azoic during methane activity and sulfide build-up. Sulfate concentrations decreased while sulfide and dissolved inorganic carbon concentrations increased during the summer. This coincided with changes in the depth and rates of bioturbation. Summer burrow depths (~0.8 cm) and rates (~0.4 cm h-1) were significantly less than spring burrow depths (~3.0 cm) and rates (~1.0 cm h-1). While sulfate reduction and OM degradation increased with temperature at a microscopic level, macroscopic OM degradation was reduced. As a result, reduced conditions dominated and a thin aerobic sediment layer, a few millimeters in thickness, was visible at the sediment surface. Decreases in macrofauna burrow depth and rates diminishes the area of influence of bioturbators, limiting bioturbation and subsequently the important ecosystem functions these organisms provide.

PMID- 29176815 TI - Growth, ammonium metabolism, and photosynthetic properties of Ulva australis (Chlorophyta) under decreasing pH and ammonium enrichment. AB - The responses of macroalgae to ocean acidification could be altered by availability of macronutrients, such as ammonium (NH4+). This study determined how the opportunistic macroalga, Ulva australis responded to simultaneous changes in decreasing pH and NH4+ enrichment. This was investigated in a week-long growth experiment across a range of predicted future pHs with ambient and enriched NH4+ treatments followed by measurements of relative growth rates (RGR), NH4+ uptake rates and pools, total chlorophyll, and tissue carbon and nitrogen content. Rapid light curves (RLCs) were used to measure the maximum relative electron transport rate (rETRmax) and maximum quantum yield of photosystem II (PSII) photochemistry (Fv/Fm). Photosynthetic capacity was derived from the RLCs and included the efficiency of light harvesting (alpha), slope of photoinhibition (beta), and the light saturation point (Ek). The results showed that NH4+ enrichment did not modify the effects of pH on RGRs, NH4+ uptake rates and pools, total chlorophyll, rETRmax, alpha, beta, Fv/Fm, tissue C and N, and the C:N ratio. However, Ek was differentially affected by pH under different NH4+ treatments. Ek increased with decreasing pH in the ambient NH4+ treatment, but not in the enriched NH4+ treatment. NH4+ enrichment increased RGRs, NH4+ pools, total chlorophyll, rETRmax, alpha, beta, Fv/Fm, and tissue N, and decreased NH4+ uptake rates and the C:N ratio. Decreased pH increased total chlorophyll content, rETRmax, Fv/Fm, and tissue N content, and decreased the C:N ratio. Therefore, the results indicate that U. australis growth is increased with NH4+ enrichment and not with decreasing pH. While decreasing pH influenced the carbon and nitrogen metabolisms of U. australis, it did not result in changes in growth. PMID- 29176816 TI - A large outbreak of Hepatitis E virus genotype 1 infection in an urban setting in Chad likely linked to household level transmission factors, 2016-2017. AB - BACKGROUND: In September 2016, three acutely jaundiced (AJS) pregnant women were admitted to Am Timan Hospital, eastern Chad. We described the outbreak and conducted a case test-negative study to identify risk factors for this genotype of HEV in an acute outbreak setting. METHODS: Active case finding using a community based surveillance network identified suspected AJS cases. Pregnant or visibly ill AJS cases presenting at hospital were tested with Assure(r) IgM HEV rapid diagnostic tests (RDTs) and some with Polymerase Chain Reaction (PCR) in Amsterdam; confirmed cases were RDT-positive and controls were RDT-negative. All answered questions around: demographics, household makeup, area of residence, handwashing practices, water collection behaviour and clinical presentation. We calculated unadjusted odds ratios (ORs) and 95% confidence intervals (95% CI). RESULTS: Between September and April 2017, 1443 AJS cases (1293 confirmed) were detected in the town(attack rate: 2%; estimated 65,000 population). PCR testing confirmed HEV genotype 1e. HEV RDTs were used for 250 AJS cases; 100 (40%) were confirmed. Risk factors for HEV infection, included: having at least two children under the age of 5 years (OR 2.1, 95%CI 1.1-4.3), having another household member with jaundice (OR 2.4, 95%CI 0.90-6.3) and, with borderline significance, living in the neighbourhoods of Riad (OR 3.8, 95%CI 1.0-1.8) or Ridina (OR 3.3, 95%CI 1.0-12.6). Cases were more likely to present with vomiting (OR 3.2, 9%CI 1.4-7.9) than controls; possibly due to selection bias. Cases were non-significantly less likely to report always washing hands before meals compared with controls (OR 0.33, 95%CI 0.1-1.1). DISCUSSION: Our study suggests household factors and area of residence (possibly linked to access to water and sanitation) play a role in HEV transmission; which could inform future outbreak responses. Ongoing sero prevalence studies will elucidate more aspects of transmission dynamics of this virus with genotype 1e. PMID- 29176818 TI - Effects of the Blob on settlement of spotted sand bass, Paralabrax maculatofasciatus, to Mission Bay, San Diego, CA. AB - The West Coast of the United States experienced variable and sometimes highly unusual oceanographic conditions between 2012 and 2015. In particular, a warm mass of surface water known as the Pacific Warm Anomaly (popularly as "The Blob") impinged on southern California in 2014, and warm-water conditions remained during the 2015 El Nino. We examine how this oceanographic variability affected delivery and individual characteristics of larval spotted sand bass (Paralabrax maculatofasciatus) to an estuarine nursery habitat in southern California. To quantify P. maculatofasciatus settlement patterns, three larval collectors were installed near the mouth of Mission Bay, San Diego CA, and retrieved weekly from June-October of 2012-2015. During 'Blob' conditions in 2014 and 2015, lower settlement rates of spotted sand bass were associated with higher sea surface temperature and lower wind speed, chlorophyll a (chl a) and upwelling. Overall, the number of settlers per day peaked at intermediate chl a values across weeks. Individual characteristics of larvae that settled in 2014-2015 were consistent with a poor feeding environment. Although settlers were longer in length in 2014 15, fish in these years had slower larval otolith growth, a longer larval duration, and a trend towards lower condition, traits that are often associated with lower survival and recruitment. This study suggests that future settlement and recruitment of P. maculatofasciatus and other fishes with similar life histories may be adversely affected in southern California if ocean temperatures continue to rise in the face of climate change.

AB - INTRODUCTION: Anemia is a public health concern among women in rural Baja California, Mexico. The purpose of this study was to identify the individual and community factors contributing to the disproportionately high prevalence of anemia among women in this region. METHODS: A cross-sectional study of 118 women (15-49 years) was performed in a rural colonia (small settlement) in Baja California, Mexico in 2012. Participants completed a survey comprised of demographic, socioeconomic, health, and dietary questions and provided a capillary blood sample. A portable HemoCue was used to measure hemoglobin and diagnose anemia. Anemic participants provided a venous blood sample for laboratory testing to elucidate the etiology of anemia. Anemic participants received vitamin supplements and nutritional counseling. Assessments of six local tiendas (community grocery stores) were performed to ascertain the types of food available for purchase within the community. RESULTS: Prevalence of anemia was 22% among women; laboratory tests revealed iron deficiency was the primary etiology in 80.8% of anemia cases. Other causes of anemia in women included vitamin B-12 deficiency (11.5%) and combined iron and vitamin B-12 deficiency (7.7%). Women from low SES households and women enrolled in the government assistance program Prospera were significantly more likely to be anemic (OR = 3.48, 95% CI 1.35-8.98 and OR = 2.49, 95% CI 1.02-6.09, respectively). Vitamin supplementation was significantly more common among non-anemic women (OR = 0.12, 95% CI 0.02-0.94). Dietary assessments showed limited consumption of iron absorption enhancing foods such as fruits and vegetables. Assessments of local tiendas revealed at least one type of meat and citrus fruit available for purchase at each store; however, leafy green vegetables were only available for purchase at one store. CONCLUSION: All cases of anemia were due to nutritional deficiencies. While vitamin supplementation is a temporary solution, improved individual nutrition knowledge and community access to iron absorption enhancing foods, particularly produce, is needed. Promoting government assistance programs like Prospera and implementing additional programs designed to improve nutrition and health literacy, in conjunction with ensuring access to nutritious foods, might reduce the high prevalence nutritional anemia within the community. PMID- 29176819 TI - Metabolism drives distribution and abundance in extremophile fish. AB - Differences in population density between species of varying size are frequently attributed to metabolic rates which are assumed to scale with body size with a slope of 0.75. This assumption is often criticised on the grounds that 0.75 scaling of metabolic rate with body size is not universal and can vary significantly depending on species and life-history. However, few studies have investigated how interspecific variation in metabolic scaling relationships affects population density in different sized species. Here we predict inter specific differences in metabolism from niche requirements, thereby allowing metabolic predictions of species distribution and abundance at fine spatial scales. Due to the differences in energetic efficiency required along harsh benign gradients, an extremophile fish (brown mudfish, Neochanna apoda) living in harsh environments had slower metabolism, and thus higher population densities, compared to a fish species (banded kokopu, Galaxias fasciatus) in physiologically more benign habitats. Interspecific differences in the intercepts for the relationship between body and density disappeared when species mass-specific metabolic rates, rather than body sizes, were used to predict density, implying population energy use was equivalent between mudfish and kokopu. Nevertheless, despite significant interspecific differences in the slope of the metabolic scaling relationships, mudfish and kokopu had a common slope for the relationship between body size and population density. These results support underlying logic of energetic equivalence between different size species implicit in metabolic theory. However, the precise slope of metabolic scaling relationships, which is the subject of much debate, may not be a reliable indicator of population density as expected under metabolic theory. PMID- 29176820 TI - Genome-wide association study for grain yield and related traits in elite wheat varieties and advanced lines using SNP markers. AB - Genetic improvement of grain yield is always an important objective in wheat breeding. Here, a genome-wide association study was conducted to parse the complex genetic composition of yield-related traits of 105 elite wheat varieties (lines) using the Wheat 90K Illumina iSelect SNP array. Nine yield-related traits, including maximum number of shoots per square meter (MSN), effective number of spikes per square meter (ESN), percentage of effective spike (PES), number of kernels per spike (KPS), thousand-kernel weight (TKW), the ratio of kernel length/kernel width (RLW), leaf-area index (LAI), plant height (PH), and grain yield (GY), were evaluated across four environments. Twenty four highly significant marker-trait associations (MTAs) (P < 0.001) were identified for nine yield-related traits on chromosomes 1A, 1D, 2A (2), 3B, 4A (2), 4B, 5A (4), 5B (4), 5D, 6B (2), 7A (2), and 7B (3), explaining 10.86-20.27% of the phenotypic variations. Of these, four major loci were identified in more than three environments, including one locus for RLW (6B), one locus for TKW (7A), and two loci for PH (7B). A cleaved amplified polymorphic sequence (CAPS) marker Td99211 for TKW on chromosome 5A was developed and validated in both a natural population composed of 372 wheat varieties (lines) and a RIL population derived from the cross of Yangxiaomai * Zhongyou 9507. The CAPS marker developed can be directly used for marker-assisted selection in wheat breeding, and the major MTAs identified can provide useful information for fine-mapping of the target genes in future studies. PMID- 29176821 TI - Familial transmission of a body-related attentional bias - An eye-tracking study in a nonclinical sample of female adolescents and their mothers. AB - BACKGROUND: Previous research indicates that body image disturbance is transmitted from mother to daughter via modeling of maternal body-related behaviors and attitudes (indirect transmission) and via maternal body-related feedback (direct transmission). So far, the transmission of body-related attentional biases, which according to cognitive-behavioral theories play a prominent role in the development and maintenance of eating disorders, has not been analyzed. The current eye-tracking study applied the concepts of direct and indirect transmission to body-related attentional biases by examining body related viewing patterns on self- and other-pictures within mother-daughter dyads. METHODS: Eye movements of N = 82 participants (n = 41 healthy female adolescents, mean age 15.82 years, SD = 1.80, and their mothers, mean age 47.78 years, SD = 4.52) were recorded while looking at whole-body pictures of themselves and a control peer. Based on fixations on self-defined attractive and unattractive body areas, visual attention bias scores were calculated for mothers and daughters, representing the pattern of body-related attention allocation. Based on mothers' fixations on their own daughter's and the adolescent peer's body, a second visual attention bias score was calculated, reflecting the mothers' viewing pattern on their own daughter. RESULTS: Analysis of variance revealed an attentional bias for self-defined unattractive body areas in adolescents. The girls' visual attention bias score correlated significantly with their mothers' bias score, indicating indirect transmission, and with their mothers' second bias score, indicating direct transmission. Moreover, the girls' bias score correlated significantly with negative body-related feedback from their mothers. CONCLUSIONS: Female adolescents show a deficit-oriented attentional bias for one's own and a peer's body. The correlated body-related attention patterns imply that attentional biases might be transmitted directly and indirectly from mothers to daughters. Results underline the potential relevance of maternal influences for the development of body image disturbance in girls and suggest specific family-based approaches for the prevention and treatment of eating disorders. PMID- 29176822 TI - Change detection in pictorial and solid scenes: The role of depth of field. AB - This paper investigates the influence of depth of field on change detection in both pictorial and solid scenes. In this work, a within-subjects experiment is conducted using a flicker paradigm, with which the hit rate and response time for change detection are obtained. The results show that depth of field has effects on change detection: the hit rate is smaller and response time is longer in the scene with small depth of field than in the scene with large depth of field or uniform blur. It is concluded that when depth of field is small and binocular disparity is not zero in a picture, the influence of depth of field on change detection is more significant than binocular disparity. This conclusion leads to the result that the change in the sharp area is detected easier and faster than in the area that is closer to the observer. PMID- 29176823 TI - Vitamin D receptor is present on the neuronal plasma membrane and is co-localized with amyloid precursor protein, ADAM10 or Nicastrin. AB - Our recent study indicated that vitamin D and its receptors are important parts of the amyloid processing pathway in neurons. Yet the role of vitamin D receptor (VDR) in amyloid pathogenesis is complex and all regulations over the production of amyloid beta cannot be explained solely with the transcriptional regulatory properties of VDR. Given that we hypothesized that VDR might exist on the neuronal plasma membrane in close proximity with amyloid precursor protein (APP) and secretase complexes. The present study primarily focused on the localization of VDR in neurons and its interaction with amyloid pathology-related proteins. The localization of VDR on neuronal membranes and its co-localization with target proteins were investigated with cell surface staining followed by immunofluorescence labelling. The FpClass was used for protein-protein interaction prediction. Our results demonstrated the localization of VDR on the neuronal plasma membrane and the co-localization of VDR and APP or ADAM10 or Nicastrin and limited co-localization of VDR and PS1. E-cadherin interaction with APP or the gamma-secretase complex may involve NOTCH1, NUMB, or FHL2, according to FpClass. This suggested complex might also include VDR, which greatly contributes to Ca+2 hemostasis with its ligand vitamin D. Consequently, we suggested that VDR might be a member of this complex also with its own non genomic action and that it can regulate the APP processing pathway in this way in neurons. PMID- 29176825 TI - The effect of spatial randomness on the average fixation time of mutants. AB - The mean conditional fixation time of a mutant is an important measure of stochastic population dynamics, widely studied in ecology and evolution. Here, we investigate the effect of spatial randomness on the mean conditional fixation time of mutants in a constant population of cells, N. Specifically, we assume that fitness values of wild type cells and mutants at different locations come from given probability distributions and do not change in time. We study spatial arrangements of cells on regular graphs with different degrees, from the circle to the complete graph, and vary assumptions on the fitness probability distributions. Some examples include: identical probability distributions for wild types and mutants; cases when only one of the cell types has random fitness values while the other has deterministic fitness; and cases where the mutants are advantaged or disadvantaged. Using analytical calculations and stochastic numerical simulations, we find that randomness has a strong impact on fixation time. In the case of complete graphs, randomness accelerates mutant fixation for all population sizes, and in the case of circular graphs, randomness delays mutant fixation for N larger than a threshold value (for small values of N, different behaviors are observed depending on the fitness distribution functions). These results emphasize fundamental differences in population dynamics under different assumptions on cell connectedness. They are explained by the existence of randomly occurring "dead zones" that can significantly delay fixation on networks with low connectivity; and by the existence of randomly occurring "lucky zones" that can facilitate fixation on networks of high connectivity. Results for death-birth and birth-death formulations of the Moran process, as well as for the (haploid) Wright Fisher model are presented. PMID- 29176826 TI - Aggregate-level lead exposure, gun violence, homicide, and rape. AB - CONTEXT: An increasing body of research has linked the geographic distribution of lead with various indicators of criminal and antisocial behavior. OBJECTIVE: The current study, using data from an ongoing project related to lead exposure in St. Louis City, MO, analyzed the association between aggregate blood lead levels and specific indicators violent crime within the city. DESIGN: Ecological study. SETTING: St. Louis, Missouri. EXPOSURE MEASURE: Blood lead levels. MAIN OUTCOME MEASURE: Official reports of violent crimes were categorized as 1) crimes involving a firearm (yes/no), 2) assault crimes (with or without a firearm), 3) robbery crimes (with or without a firearm), 4) homicides and 5) rape. RESULTS: With the exception of rape, aggregate blood-lead levels were statistically significant predictors of violent crime at the census tract level. The risk ratios for each of the outcome measures were as follows: firearm crimes 1.03 (1.03-1.04), assault crimes 1.03 (1.02-1.03), robbery crimes 1.03 (1.02-1.04), homicide 1.03 (1.01, 1.04), and rape 1.01 (0.99-1.03). CONCLUSIONS: Extending prior research in St. Louis, results suggest that aggregated lead exposure at the census tract level predicted crime outcomes, even after accounting for important sociological variables. Moving forward, a more developed understanding of aggregate level crime may necessitate a shift toward studying the synergy between sociological and biological risk factors such as lead exposure. PMID- 29176824 TI - Safety and efficacy of a freeze-dried trivalent antivenom for snakebites in the Brazilian Amazon: An open randomized controlled phase IIb clinical trial. AB - BACKGROUND: In tropical areas, a major concern regarding snakebites treatment effectiveness relates to the failure in liquid antivenom (AV) distribution due to the lack of an adequate cold chain in remote areas. To minimize this problem, freeze-drying has been suggested to improve AV stability. METHODS AND FINDINGS: This study compares the safety and efficacy of a freeze-dried trivalent antivenom (FDTAV) and the standard liquid AV provided by the Brazilian Ministry of Health (SLAV) to treat Bothrops, Lachesis and Crotalus snakebites. This was a prospective, randomized, open, phase IIb trial, carried out from June 2005 to May 2008 in the Brazilian Amazon. Primary efficacy endpoints were the suppression of clinical manifestations and return of hemostasis and renal function markers to normal ranges within the first 24 hours of follow-up. Primary safety endpoint was the presence of early adverse reactions (EAR) in the first 24 hours after treatment. FDTAV thermal stability was determined by estimating AV potency over one year at 56 degrees C. Of the patients recruited, 65 and 51 were assigned to FDTAV and SLAV groups, respectively. Only mild EARs were reported, and they were not different between groups. There were no differences in fibrinogen (p = 0.911) and clotting time (p = 0.982) recovery between FDTAV and SLAV treated groups for Bothrops snakebites. For Lachesis and Crotalus snakebites, coagulation parameters and creatine phosphokinase presented normal values 24 hours after AV therapy for both antivenoms. CONCLUSIONS/SIGNIFICANCE: Since promising results were observed for efficacy, safety and thermal stability, our results indicate that FDTAV is suitable for a larger phase III trial.

PMID- 29176827 TI - Who is more likely to be obese or overweight among siblings? A nationally representative study in rural China. AB - BACKGROUND: The aims of this study were to determine the association between sibling rank and childhood obesity among children <= 5 years of age in rural China, and to investigate the effect of child gender and the obesity status of other siblings on this association. METHODS: Data from the China Family Panel Studies, a nationally representative survey, was used for the analysis. Sibling rank was defined as the birth order of all children with the same biological mother. A total of 1116 children <= 5 years of age were divided into four groups: children without siblings, first-born children, second-born children, and third born or younger children. For each child, the body mass index and standard deviation (BMI z score) was calculated according to WHO standards; children with BMI z scores > 2 were classified as obese or overweight (ObOw). Logistic regression models were used to estimate the association between sibling rank and ObOw status, and the possible influence of gender and ObOw status among other siblings. RESULTS: The second and third-born or younger children had a significantly higher risk of becoming ObOw than children without siblings (odds ratio [OR]: 1.32, 95% confidence interval [CI]: 1.07-1.63 and OR:1.38, 95% CI: 1.17-1.63, respectively). Specifically, female second-born children and male third-born or younger children had a significantly higher risk of ObOw (OR: 1.50, 95% CI: 1.11-2.01 and OR: 1.57, 95% CI: 1.07-2.32, respectively). Having an ObOw sibling increased the probability of being ObOw and the magnitude of the effect was larger if siblings were younger. CONCLUSIONS: Sibling rank was shown to be associated with ObOw status among children 0-5 years of age in rural China. Our findings can help healthcare practitioners and authorities to identify children at risk of obesity. Future studies should focus on the mechanisms of this association. PMID- 29176829 TI - Tobacco industry attempts to frame smoking as a 'disability' under the 1990 Americans with Disabilities Act. AB - Using the Truth Tobacco Industry Documents Library and Congressional records, we examined the tobacco industry's involvement with the 1990 Americans with Disabilities Act (ADA). During legislative drafting of the ADA (1989-1990), the Tobacco Institute, the tobacco industry's lobbying and public relations arm at the time, worked with industry lawyers and civil rights groups to include smoking in the ADA's definition of "disability." Focus was on smoking as a perceived rather than actual disability so that tobacco companies could maintain that smoking is not addictive. Language that would have explicitly excluded smoking from ADA coverage was weakened or omitted. Tobacco Institute lawyers did not think the argument that smokers are "disabled" would convince the courts, so in the two years after the ADA was signed into law, the Tobacco Institute paid a lawyer to conduct media tours, seminars, and write articles to convince employers that hiring only non-smokers would violate the ADA. The ultimate goal of these activities was to deter employers from promoting a healthy, tobacco-free workforce and, more broadly, to promote the social acceptability of smoking. Employers and policy makers need to be aware that tobacco use is not protected by the ADA and should not be misled by tobacco industry efforts to insinuate otherwise. PMID- 29176828 TI - T cell recognition of Mycobacterium tuberculosis peptides presented by HLA-E derived from infected human cells. AB - HLA-E is a non-conventional MHC Class I molecule that has been recently demonstrated to present pathogen-derived ligands, resulting in the TCR-dependent activation of alphabeta CD8+ T cells. The goal of this study was to characterize the ligandome displayed by HLA-E following infection with Mycobacterium tuberculosis (Mtb) using an in-depth mass spectrometry approach. Here we identified 28 Mtb ligands derived from 13 different source proteins, including the Esx family of proteins. When tested for activity with CD8+ T cells isolated from sixteen donors, nine of the ligands elicited an IFN-gamma response from at least one donor, with fourteen of 16 donors responding to the Rv0634A19-29 peptide. Further evaluation of this immunodominant peptide response confirmed HLA E restriction and the presence of Rv0634A19-29-reactive CD8+ T cells in the peripheral blood of human donors. The identification of an Mtb HLA-E ligand that is commonly recognized may provide a target for a non-traditional vaccine strategy. PMID- 29176830 TI - The effect of dam construction on the movement of dwarf caimans, Paleosuchus trigonatus and Paleosuchus palpebrosus, in Brazilian Amazonia. AB - Run-of-the-river hydroelectric dams cause changes in seasonal inundation of the floodplains, and this may cause displacement of semi-aquatic vertebrates present before dam construction. This study evaluated the movement of crocodilians before and after the filling of the Santo Antonio hydroelectric reservoir on the Madeira River in the Brazilian Amazon, which occurred in November 2011. We radio-tracked four adult male Paleosuchus palpebrosus and four adult male Paleosuchus trigonatus before and after the formation of the reservoir between 2011 and 2013. The home ranges of the P. palpebrosus varied from < 1 km2 to 91 km2 and the home ranges of the P. trigonatus varied from < 1km2 to 5 km2. The species responded differently to time since filling and water level in weekly movement and home range. However, overall the dam appears to have had little effect on the use of space by the individuals that were present before dam construction. PMID- 29176832 TI - A user exposure based approach for non-structural road network vulnerability analysis. AB - Aiming at the dense urban road network vulnerability without structural negative consequences, this paper proposes a novel non-structural road network vulnerability analysis framework. Three aspects of the framework are mainly described: (i) the rationality of non-structural road network vulnerability, (ii) the metrics for negative consequences accounting for variant road conditions, and (iii) the introduction of a new vulnerability index based on user exposure. Based on the proposed methodology, a case study in the Sioux Falls network which was usually threatened by regular heavy snow during wintertime is detailedly discussed. The vulnerability ranking of links of Sioux Falls network with respect to heavy snow scenario is identified. As a result of non-structural consequences accompanied by conceivable degeneration of network, there are significant increases in generalized travel time costs which are measurements for "emotionally hurt" of topological road network. PMID- 29176831 TI - SAGA mediates transcription from the TATA-like element independently of Taf1p/TFIID but dependent on core promoter structures in Saccharomyces cerevisiae. AB - In Saccharomyces cerevisiae, core promoters of class II genes contain a TATA element, either a TATA box (TATA[A/T]A[A/T][A/G]) or TATA-like element (1 or 2 bp mismatched version of the TATA box). The TATA element directs the assembly of the preinitiation complex (PIC) to ensure accurate transcriptional initiation. It has been proposed the PIC is assembled by two distinct pathways in which TBP is delivered by TFIID or SAGA, leading to the widely accepted model that these complexes mediate transcription mainly from TATA-like element- or TATA box containing promoters, respectively. Although both complexes are involved in transcription of nearly all class II genes, it remains unclear how efficiently SAGA mediates transcription from TATA-like element-containing promoters independently of TFIID. We found that transcription from the TATA box-containing AGP1 promoter was greatly stimulated in a Spt3p-dependent manner after inactivation of Taf1p/TFIID. Thus, this promoter provides a novel experimental system in which to evaluate SAGA-mediated transcription from TATA-like element(s). We quantitatively measured transcription from various TATA-like elements in the Taf1p-dependent CYC1 promoter and Taf1p-independent AGP1 promoter. The results revealed that SAGA could mediate transcription from at least some TATA-like elements independently of Taf1p/TFIID, and that Taf1p dependence or -independence is highly robust with respect to variation of the TATA sequence. Furthermore, chimeric promoter mapping revealed that Taf1p dependence or independence was conferred by the upstream activating sequence (UAS), whereas Spt3p-dependent transcriptional stimulation after inactivation of Taf1p/TFIID was specific to the AGP1 promoter and dependent on core promoter regions other than the TATA box. These results suggest that TFIID and/or SAGA are regulated in two steps: the UAS first specifies TFIID or SAGA as the predominant factor on a given promoter, and then the core promoter structure guides the pertinent factor to conduct transcription in an appropriate manner. PMID- 29176833 TI - Characterization of small-to-medium head-and-face dimensions for developing respirator fit test panels and evaluating fit of filtering facepiece respirators with different faceseal design. AB - A respirator fit test panel (RFTP) with facial size distribution representative of intended users is essential to the evaluation of respirator fit for new models of respirators. In this study an anthropometric survey was conducted among youths representing respirator users in mid-Taiwan to characterize head-and-face dimensions key to RFTPs for application to small-to-medium facial features. The participants were fit-tested for three N95 masks of different facepiece design and the results compared to facial size distribution specified in the RFTPs of bivariate and principal component analysis design developed in this study to realize the influence of facial characteristics to respirator fit in relation to facepiece design. Nineteen dimensions were measured for 206 participants. In fit testing the qualitative fit test (QLFT) procedures prescribed by the U.S. Occupational Safety and Health Administration were adopted. As the results show, the bizygomatic breadth of the male and female participants were 90.1 and 90.8% of their counterparts reported for the U.S. youths (P < 0.001), respectively. Compared to the bivariate distribution, the PCA design better accommodated variation in facial contours among different respirator user groups or populations, with the RFTPs reported in this study and from literature consistently covering over 92% of the participants. Overall, the facial fit of filtering facepieces increased with increasing facial dimensions. The total percentages of the tests wherein the final maneuver being completed was "Moving head up-and-down", "Talking" or "Bending over" in bivariate and PCA RFTPs were 13.3-61.9% and 22.9-52.8%, respectively. The respirators with a three-panel flat fold structured in the facepiece provided greater fit, particularly when the users moved heads. When the facial size distribution in a bivariate RFTP did not sufficiently represent petite facial size, the fit testing was inclined to overestimate the general fit, thus for small-to-medium facial dimensions a distinct RFTP should be considered. PMID- 29176834 TI - Novel scintillating material 2-(4-styrylphenyl)benzoxazole for the fully digital and MRI compatible J-PET tomograph based on plastic scintillators. AB - A novel plastic scintillator is developed for the application in the digital positron emission tomography (PET). The novelty of the concept lies in application of the 2-(4-styrylphenyl)benzoxazole as a wavelength shifter. The substance has not been used as scintillator dopant before. A dopant shifts the scintillation spectrum towards longer wavelengths making it more suitable for applications in scintillators of long strips geometry and light detection with digital silicon photomultipliers. These features open perspectives for the construction of the cost-effective and MRI-compatible PET scanner with the large field of view. In this article we present the synthesis method and characterize performance of the elaborated scintillator by determining its light emission spectrum, light emission efficiency, rising and decay time of the scintillation pulses and resulting timing resolution when applied in the positron emission tomography. The optimal concentration of the novel wavelength shifter was established by maximizing the light output and it was found to be 0.05 0/00 for cuboidal scintillator with dimensions of 14 mm x 14 mm x 20 mm. PMID- 29176836 TI - Competence in metered dose inhaler technique among community pharmacy professionals in Gondar town, Northwest Ethiopia: Knowledge and skill gap analysis. AB - BACKGROUND: When compared to systemic administration, if used correctly inhalers deliver a smaller enough percent of the drug right to the site of action in the lungs, with a faster onset of effect and with reduced systemic availability that minimizes adverse effects. However, the health professionals' and patients' use of metered dose inhaler is poor. OBJECTIVE: This study was aimed to explore community pharmacy professionals' (pharmacists' and druggists') competency on metered dose inhaler (MDI) technique. METHOD: A cross sectional study was employed on pharmacy professionals working in community drug retail outlets in Gondar town, northwest Ethiopia from March to May 2017. Evaluation tool was originally taken and adapted from the National Asthma Education and Prevention Programmes of America (NAEPP) step criteria for the demonstration of a metered dose inhaler to score the knowledge/proficiency of using the inhaler. RESULT: Among 70 community pharmacy professionals approached, 62 (32 pharmacists and 30 druggists/Pharmacy technicians) completed the survey with a response rate of 85.6%. Only three (4.8%) respondents were competent by demonstrating the vital steps correctly. Overall, only 13 participants got score seven or above, but most of them had missed the essential steps which included steps 1, 2, 5, 6, 7 or 8. There was a significant difference (P = 0.015) in competency of demonstrating adequate inhalational technique among respondents who took training on basic inhalational techniques and who did not. CONCLUSION: This study shown that, community pharmacy professionals' competency of MDI technique was very poor. So as to better incorporate community pharmacies into future asthma illness management and optimize the contribution of pharmacists, interventions would emphasis to improve the total competence of community pharmacy professionals through establishing and providing regular educational programs. PMID- 29176835 TI - Enhanced eicosapentaenoic acid production by a new deep-sea marine bacterium Shewanella electrodiphila MAR441T. AB - Omega-3 fatty acids are products of secondary metabolism, essential for growth and important for human health. Although there are numerous reports of bacterial production of omega-3 fatty acids, less information is available on the biotechnological production of these compounds from bacteria. The production of eicosapentaenoic acid (EPA, 20:5omega3) by a new species of marine bacteria Shewanella electrodiphila MAR441T was investigated under different fermentation conditions. This strain produced a high percentage (up to 26%) of total fatty acids and high yields (mg / g of biomass) of EPA at or below the optimal growth temperature. At higher growth temperatures these values decreased greatly. The amount of EPA produced was affected by the carbon source, which also influenced fatty acid composition. This strain required Na+ for growth and EPA synthesis and cells harvested at late exponential or early stationary phase had a higher EPA content. Both the highest amounts (20 mg g-1) and highest percent EPA content (18%) occurred with growth on L-proline and (NH4)2SO4. The addition of cerulenin further enhanced EPA production to 30 mg g-1. Chemical mutagenesis using NTG allowed the isolation of mutants with improved levels of EPA content (from 9.7 to 15.8 mg g-1) when grown at 15 degrees C. Thus, the yields of EPA could be substantially enhanced without the need for recombinant DNA technology, often a commercial requirement for food supplement manufacture. PMID- 29176837 TI - Factors affecting foveal avascular zone in healthy eyes: An examination using swept-source optical coherence tomography angiography. AB - OBJECTIVE: To examine factors affecting foveal avascular zone (FAZ) area in healthy eyes using swept-source optical coherence tomography angiography (OCTA). METHODS: This prospective, cross-sectional study included 144 eyes of 144 individuals (77 women, 67 men) with a best corrected visual acuity of at least 20/20 and no history of ocular disorders. The area of the superficial FAZ was assessed using OCTA. Age, gender, central retinal thickness (CRT), retinal vascular density, refractive error, and axial length were examined to determine associations with FAZ area. RESULTS: The mean age of the subjects was 42.1 +/- 20.2 years (range: 10-79 years). The mean FAZ area was 0.32 +/- 0.11 mm2, while the mean retinal vascular density was 35.53 +/- 0.92%. Multivariate regression analysis was performed using FAZ area as the dependent variable and age, gender, CRT, retinal vascular density, refractive error, and axial length as independent variables. The results of this analysis demonstrate that CRT and retinal vascular density were significantly associated with FAZ area in our sample (P < 0.001, R2 = 0.425). Age, gender, refractive error, and axial length were not significantly correlated with FAZ area, while CRT and retinal vascular density were negatively correlated with FAZ area (CRT: P < 0.001, R2 = 0.356; retinal vascular density: P < 0.001, R2 = 0.189). CONCLUSIONS: OCTA results suggest that CRT and retinal vascular density negatively affect FAZ area in healthy eyes.

Because group-I metabotropic glutamate receptors (mGluR1 and mGluR5) can form complexes with the cellular prion protein (PrPC), we investigated the impact of mGluR1 and mGluR5 inhibition on prion toxicity ex vivo and in vivo. We found that pharmacological inhibition of mGluR1 and mGluR5 antagonized dose dependently the neurotoxicity triggered by prion infection and by prion-mimetic anti-PrPC antibodies in organotypic brain slices. Prion-mimetic antibodies increased mGluR5 clustering around dendritic spines, mimicking the toxicity of Abeta oligomers. Oral treatment with the mGluR5 inhibitor, MPEP, delayed the onset of motor deficits and moderately prolonged survival of prion-infected mice. Although group-I mGluR inhibition was not curative, these results suggest that it may alleviate the neurological dysfunctions induced by prion diseases.

AB - Pleistocene climatic oscillations favoured the expansion of grassland ecosystems and open vegetation landscapes throughout the Neotropics, and influenced the evolutionary history of species adapted to such environments. In this study, we sampled populations of the rodent Oxymycterus nasutus endemic to open areas in the Pampas and Atlantic Forest biomes to assess the tempo and mode of population divergence using an integrative approach, including coalescence theory, ecological niche models, and morphometry. Our results indicated that these O. nasutus populations exhibited high levels of genetic structure. Six major mtDNA clades were found, structuring these biomes into distinct groups. Estimates of their divergence times was indicated to be 0.571 myr. The high degree of genetic structure is reflected in the analyses of geometric morphometric; skull differences between lineages in the two ecoregions were detected. During the last glacial maximum, there was a strong increase in suitable abiotic conditions for O. nasutus. Distinct molecular markers revealed a population expansion over time, with a possible demographic retraction during the post-glacial period. Considering that all clades coalesce with the last interglacial maximum, our results indicated that reduction in suitable conditions during this period may have resulted in a possible vicariance associated with refuge isolation.

AB - Human excreta is a low cost source of nutrients vital to plant growth, but also a source of pathogens transmissible to people and animals. We investigated the cost savings and infection risk of soil transmitted helminths (STHs) in four scenarios where farmers used either inorganic fertilizer or fresh/composted human excreta supplemented by inorganic fertilizer to meet the nutrient requirements of rice paddies in the Red River Delta, Vietnam. Our study included two main components: 1) a risk estimate of STH infection for farmers who handle fresh excreta, determined by systematic review and meta-analysis; and 2) a cost estimate of fertilizing rice paddies, determined by nutrient assessment of excreta, a retailer survey of inorganic fertilizer costs, and a literature review to identify region-specific inputs. Our findings suggest that farmers who reuse fresh excreta are 1.24 (95% CI: 1.13-1.37, p-value<0.001) times more likely to be infected with any STH than those who do not handle excreta or who compost appropriately, and that risk varies by STH type (Ascaris lumbricoides RR = 1.17, 95% CI = 0.87-1.58, p-value = 0.29; Hookworm RR = 1.02, 95% CI = 0.50-2.06, p value = 0.96; Trichuris trichiura RR = 1.38, 95% CI = 0.79-2.42, p-value = 0.26). Average cost-savings were highest for farmers using fresh excreta (847,000 VND) followed by those who composted for 6 months as recommended by the WHO (312,000 VND) and those who composted for a shorter time (5 months) with lime supplementation (37,000 VND/yr); however, this study did not assess healthcare costs of treating acute or chronic STH infections in the target group. Our study provides evidence that farmers in the Red River Delta are able to use a renewable and locally available resource to their economic advantage, while minimizing the risk of STH infection. PMID- 29176841 TI - Salient object segmentation based on active contouring. AB - Traditional saliency detection algorithms lack object semantic character, and the segmentation algorithms cannot highlight the saliency of the segmentation regions. In order to compensate for the defects of these two algorithms, the salient object segmentation model, which is a novel combination of two algorithms, is established in this paper. With the help of a priori knowledge of image boundary background traits, the K-means++ algorithm is used to cluster the pixels for each region; in line with the sensitivity of the human eye to color and with its attention mechanism, the joint probability distribution of the regional contrast ratio and spatial saliency is established. The selection of the salient area is based on the probabilities, for which the region boundary is taken as the initial curve, and the level-set algorithm is used to perform the salient object segmentation of the image. The curve convergence condition is established according to the confidence level for the segmented region, thus avoiding over-convergence of the segmentation curve. With this method, the salient region boundary is adjacent to the object contour, so the curve evolution time is shorter, and compared with the traditional Li algorithm, the proposed algorithm has higher segmentation evaluation scores, with the additional benefit of emphasizing the importance of the object. PMID- 29176842 TI - Allergenic food introduction and risk of childhood atopic diseases. AB - BACKGROUND: The role of timing and diversity of allergenic food introduction in the development of childhood allergic sensitization and atopic diseases is controversial. OBJECTIVE: To examine whether timing and diversity of allergenic food introduction are associated with allergic sensitization, allergy and eczema in children until age 10 years. MATERIALS AND METHODS: This study among 5,202 children was performed in a population-based prospective cohort. Timing (age <=6 months vs. >6 months) and diversity (0, 1, 2 and >=3 foods) of allergenic food (cow's milk, hen's egg, peanut, tree nuts, soy and gluten) introduction were assessed by questionnaires at ages 6 and 12 months. At age 10 years, inhalant and food allergic sensitization were measured by skin prick tests, and physician diagnosed inhalant and food allergy by questionnaire. Data on parental-reported physician-diagnosed eczema were obtained from birth until age 10 years. RESULTS: Children introduced to gluten at age <=6 months had a decreased risk of eczema (aOR (95% CI): 0.84 (0.72, 0.99)), compared with children introduced to gluten at age >6 months. However, timing of allergenic food introduction was not associated with allergic sensitization or physician-diagnosed allergy. Children introduced to >=3 allergenic foods at age <=6 months had a decreased risk of physician diagnosed inhalant allergy (0.64 (0.42, 0.98)), compared with children not introduced to any allergenic food at age <=6 months. However, diversity of allergenic food introduction was not associated with allergic sensitization, physician-diagnosed food allergy or eczema. CONCLUSION: Neither timing nor diversity of allergenic food introduction was consistently associated with childhood allergic sensitization, allergy or eczema. PMID- 29176843 TI - HIV-1 and cocaine disrupt dopamine reuptake and medium spiny neurons in female rat striatum. AB - HIV-1 and addictive drugs, such as cocaine (COC), may act in combination to produce serious neurological complications. In the present experiments, striatal brain slices from HIV-1 transgenic (Tg) and F344 control female rats were studied. First, we examined dopamine (DA) reuptake in control, HIV-1, COC-treated (5uM) and HIV-1+COC-treated, striatal slices using fast scan cyclic voltammetry. COC-treated striatal slices from F344 control animals significantly increased DA reuptake time (T80), relative to untreated control slices. In contrast, in HIV-1 Tg striatal slices, DA reuptake time was extended by HIV-1, which was not further altered by COC treatment. Second, analysis of medium spiny neuronal populations from striatal brain slices found that controls treated with cocaine displayed increases in spine length, whereas cocaine treated HIV-1 slices displayed decreased spine length. Taken together, the current study provides evidence for dysfunction of the dopamine transporter (DAT) in mediating DA reuptake in HIV-1 Tg rats and limited responses to acute COC exposure. Collectively, dysfunction of the DAT reuptake and altered dendritic spine morphology of the MSNs, suggest a functional disruption of the dopamine system within the HIV-1 Tg rat. PMID- 29176844 TI - Prospective comparison among transient elastography, supersonic shear imaging, and ARFI imaging for predicting fibrosis in nonalcoholic fatty liver disease. AB - The diagnostic performance of supersonic shear imaging (SSI) in comparison with those of transient elastography (TE) and acoustic radiation force impulse imaging (ARFI) for staging fibrosis in nonalcoholic fatty liver disease (NAFLD) patients has not been fully assessed, especially in Asian populations with relatively lean NAFLD compared to white populations. Thus, we focused on comparing the diagnostic performances of TE, ARFI, and SSI for staging fibrosis in a head-to-head manner, and identifying the clinical, anthropometric, biochemical, and histological features which might affect liver stiffness measurement (LSM) in our prospective biopsy-proven NAFLD cohort. In this study, ninety-four patients with biopsy proven NAFLD were included prospectively. Liver stiffness was measured using TE, SSI, and ARFI within 1 month of liver biopsy. The diagnostic performance for staging fibrosis was assessed using receiver operating characteristic (ROC) analysis. Anthropometric data were evaluated as covariates influencing LSM by regression analyses. Liver stiffness correlated with fibrosis stage (p < 0.05); the area under the ROC curve of TE (kPa), SSI (kPa), and ARFI (m/s) were as follows: 0.757, 0.759, and 0.657 for significant fibrosis and 0.870, 0.809, and 0.873 for advanced fibrosis. Anthropometric traits were significant confounders affecting SSI, while serum liver injury markers significantly confounded TE and ARFI. In conclusion, the LSM methods had similar diagnostic performance for staging fibrosis in patients with NAFLD. Pre-LSM anthropometric evaluation may help predict the reliability of SSI. PMID- 29176845 TI - Minimal 2'-O-methyl phosphorothioate linkage modification pattern of synthetic guide RNAs for increased stability and efficient CRISPR-Cas9 gene editing avoiding cellular toxicity. AB - Since its initial application in mammalian cells, CRISPR-Cas9 has rapidly become a preferred method for genome engineering experiments. The Cas9 nuclease is targeted to genomic DNA using guide RNAs (gRNA), either as the native dual RNA system consisting of a DNA-targeting CRISPR RNA (crRNA) and a trans-activating crRNA (tracrRNA), or as a chimeric single guide RNA (sgRNA). Entirely DNA-free CRISPR-Cas9 systems using either Cas9 protein or Cas9 mRNA and chemically synthesized gRNAs allow for transient expression of CRISPR-Cas9 components, thereby reducing the potential for off-targeting, which is a significant advantage in therapeutic applications. In addition, the use of synthetic gRNA allows for the incorporation of chemical modifications for enhanced properties including improved stability. Previous studies have demonstrated the utility of chemically modified gRNAs, but have focused on one pattern with multiple modifications in co-electroporation with Cas9 mRNA or multiple modifications and patterns with Cas9 plasmid lipid co-transfections. Here we present gene editing results using a series of chemically modified synthetic sgRNA molecules and chemically modified crRNA:tracrRNA molecules in both electroporation and lipid transfection assessing indel formation and/or phenotypic gene knockout. We show that while modifications are required for co-electroporation with Cas9 mRNA, some modification patterns of the gRNA are toxic to cells compared to the unmodified gRNA and most modification patterns do not significantly improve gene editing efficiency. We also present modification patterns of the gRNA that can modestly improve Cas9 gene editing efficiency when co-transfected with Cas9 mRNA or Cas9 protein (> 1.5-fold difference). These results indicate that for certain applications, including those relevant to primary cells, the incorporation of some, but not all chemical modification patterns on synthetic crRNA:tracrRNA or sgRNA can be beneficial to CRISPR-Cas9 gene editing. PMID- 29176846 TI - Effect of drying procedures on the physicochemical properties and antioxidant activities of polysaccharides from Crassostrea gigas. AB - Crassostrea gigas polysaccharides (CGP) were obtained by different drying methods: freeze-drying (FD), spray-drying (SD) or rotary evaporation-drying (RED). The physicochemical properties of CGP were evaluated on the basis of polysaccharide content, protein content, color characteristics, FT-IR spectroscopy, differential scanning calorimetry (DSC), and scanning electron microscopy (SEM). Antioxidant activities were researched three different free radicals, including DPPH free radicals, ABTS free radicals and reducing power. The results demonstrated that FDCGP, SDCGP and REDCGP have different physicochemical properties and antioxidant activities. Contrasted with FDCGP and REDCGP, SDCGP exhibited stronger antioxidant abilities. Therefore, considering the polysaccharides appearances and antioxidant activities, the spray drying method is a decent selection for the preparation of such polysaccharides, and it should be selected for application in the food industry. PMID- 29176847 TI - Strawberry: Fast and accurate genome-guided transcript reconstruction and quantification from RNA-Seq. AB - : We propose a novel method and software tool, Strawberry, for transcript reconstruction and quantification from RNA-Seq data under the guidance of genome alignment and independent of gene annotation. Strawberry consists of two modules: assembly and quantification. The novelty of Strawberry is that the two modules use different optimization frameworks but utilize the same data graph structure, which allows a highly efficient, expandable and accurate algorithm for dealing large data. The assembly module parses aligned reads into splicing graphs, and uses network flow algorithms to select the most likely transcripts. The quantification module uses a latent class model to assign read counts from the nodes of splicing graphs to transcripts. Strawberry simultaneously estimates the transcript abundances and corrects for sequencing bias through an EM algorithm. Based on simulations, Strawberry outperforms Cufflinks and StringTie in terms of both assembly and quantification accuracies. Under the evaluation of a real data set, the estimated transcript expression by Strawberry has the highest correlation with Nanostring probe counts, an independent experiment measure for transcript expression. AVAILABILITY: Strawberry is written in C++14, and is available as open source software at https://github.com/ruolin/strawberry under the MIT license. PMID- 29176848 TI - Dynamics of epizootic hemorrhagic disease virus infection within the vector, Culicoides sonorensis (Diptera: Ceratopogonidae). AB - Culicoides sonorensis biting midges are confirmed vectors of epizootic hemorrhagic disease virus (EHDV), which causes mortality in white-tailed deer and ruminant populations. Currently, of the seven EHDV serotypes, only 1, 2, and 6 are detected in the USA, and very few studies have focused on the infection time course of these serotypes within the midge. The objective of this current research was to characterize EHDV-2 infection within the midge by measuring infection prevalence, virus dissemination, and viral load over the course of infection. Midges were fed a blood meal containing 106.9 PFU/ml EHDV-2, collected every 12 h from 0-2 days post feeding (dpf) and daily from 3-10 dpf, and cohorts of 20 C. sonorensis were processed using techniques that assessed EHDV infection and dissemination. Cytopathic effect assays and quantitative (q)PCR were used to determine infection prevalence, revealing a 50% infection rate by 10 dpf using both methods. Using immunohistochemistry, EHDV-2 infection was detectable at 5 dpf, and shown to disseminate from the midgut to other tissues, including fat body, eyes, and salivary glands by 5 dpf. Stain intensity increased from 5-8 dpf, indicating replication of EHDV-2 in secondary infection sites after dissemination. This finding is also supported by trends in viral load over time as determined by plaque assays and qPCR. An increase in titer between 4-5 dpf correlated with viral replication in the midgut as seen with staining at day 5, while the subsequent gradual increase in viral load from 8-10 dpf suggested viral replication in midges with disseminated infection. Overall, the data presented herein suggest that EHDV-2 disseminates via the hemolymph to secondary infection sites throughout the midge and demonstrate a high potential for transmission at five days at 25 degrees C after an infective blood-meal. PMID- 29176849 TI - Association between non-barrier modern contraceptive use and condomless sex among HIV-positive female sex workers in Mombasa, Kenya: A prospective cohort analysis. AB - BACKGROUND: As access to antiretroviral therapy in sub-Saharan Africa continues to expand, more women with HIV can expect to survive through their reproductive years. Modern contraceptives can help women choose the timing and spacing of childbearing. However, concerns remain that women with HIV who use non-barrier forms of modern contraception may engage in more condomless sex because of their decreased risk of unintended pregnancy. We examined whether non-barrier modern contraceptive use by HIV-positive female sex workers was associated with increased frequency of recent condomless sex, measured by detection of prostate specific antigen (PSA) in vaginal secretions. METHODS: Women who were HIV positive and reported transactional sex were included in this analysis. Pregnant and post-menopausal follow-up time was excluded, as were visits at which women reported trying to get pregnant. At enrollment and quarterly follow-up visits, a pelvic speculum examination with collection of vaginal secretions was conducted for detection of PSA. In addition, women completed a structured face-to-face interview about their current contraceptive methods and sexual risk behavior at enrollment and monthly follow-up visits. Log-binomial generalized estimating equations regression was used to test for associations between non-barrier modern contraceptive use and detection of PSA in vaginal secretions and self-reported condomless sex. Data from October 2012 through September 2014 were included in this analysis. RESULTS: Overall, 314 women contributed 1,583 quarterly examination visits. There was minimal difference in PSA detection at contraceptive-exposed versus contraceptive-unexposed visits (adjusted relative risk [aRR] 1.28, 95% confidence interval [95% CI] 0.93-1.76). There was a higher rate of self-reported condomless sex at visits where women reported using modern contraceptives, but this difference was not statistically significant after adjustment for potential confounding factors (aRR 1.59, 95% CI 0.98-2.58). CONCLUSION: Non-barrier methods of modern contraception were not associated with increased risk of objective evidence of condomless sex. PMID- 29176850 TI - A 23-year retrospective investigation of Salmonella Typhi and Salmonella Paratyphi isolated in a tertiary Kathmandu hospital. AB - BACKGROUND: Salmonella serovars Typhi (S. Typhi) and Paratyphi A (S. Paratyphi A), the causative agents of enteric fever, have been routinely isolated organisms from the blood of febrile patients in the Kathmandu Valley since the early 1990s. Susceptibility against commonly used antimicrobials for treating enteric fever has gradually changed throughout South Asia since this time, posing serious treatment challenges. Here, we aimed to longitudinally describe trends in the isolation of Salmonella enterica and assess changes in their antimicrobial susceptibility in Kathmandu over a 23-year period. METHODS: We conducted a retrospective analysis of standardised microbiological data from April 1992 to December 2014 at a single healthcare facility in Kathmandu, examining time trends of Salmonella-associated bacteraemia and the corresponding antimicrobial susceptibility profiles of the isolated organisms. RESULTS: Over 23 years there were 30,353 positive blood cultures. Salmonella enterica accounted for 65.4% (19,857/30,353) of all the bacteria positive blood cultures. S. Typhi and S. Paratyphi A were the dominant serovars, constituting 68.5% (13,592/19,857) and 30.5% (6,057/19,857) of all isolated Salmonellae. We observed (i) a peak in the number of Salmonella-positive cultures in 2002, a year of heavy rainfall and flooding in the Kathmandu Valley, followed by a decline toward pre-flood baseline by 2014, (ii) an increase in the proportion of S. Paratyphi in all Salmonella positive cultures between 1992 and 2014, (iii) a decrease in the prevalence of MDR for both S. Typhi and S. Paratyphi, and (iv) a recent increase in fluoroquinolone non-susceptibility in both S. Typhi and S. Paratyphi isolates. CONCLUSIONS: Our work describes significant changes in the epidemiology of Salmonella enterica in the Kathmandu Valley during the last quarter of a century. We highlight the need to examine current treatment protocols for enteric fever and suggest a change from fluoroquinolone monotherapy to combination therapies of macrolides or cephalosporins along with older first-line antimicrobials that have regained their efficacy. PMID- 29176851 TI - Economics of One Health: Costs and benefits of integrated West Nile virus surveillance in Emilia-Romagna. AB - Since 2013 in Emilia-Romagna, Italy, surveillance information generated in the public health and in the animal health sectors has been shared and used to guide public health interventions to mitigate the risk of West Nile virus (WNV) transmission via blood transfusion. The objective of the current study was to identify and estimate the costs and benefits associated with this One Health surveillance approach, and to compare it to an approach that does not integrate animal health information in blood donations safety policy (uni-sectoral scenario). Costs of human, animal, and entomological surveillance, sharing of information, and triggered interventions were estimated. Benefits were quantified as the averted costs of potential human cases of WNV neuroinvasive disease associated to infected blood transfusion. In the 2009-2015 period, the One Health approach was estimated to represent a cost saving of ?160,921 compared to the uni sectoral scenario. Blood donation screening was the main cost for both scenarios. The One Health approach further allowed savings of ?1.21 million in terms of avoided tests on blood units. Benefits of the One Health approach due to short term costs of hospitalization and compensation for transfusion-associated disease potentially avoided, were estimated to range from ?0 to ?2.98 million according to the probability of developing WNV neuroinvasive disease after receiving an infected blood transfusion. PMID- 29176852 TI - How does trust affect acceptance of a nuclear power plant (NPP): A survey among people living with Qinshan NPP in China. AB - It is difficult to know whether different dimensions of trust have different effects on local residents' acceptance of nuclear power plants (NPPs). In previous research such trust has been considered as a single dimensional concept. This paper divides trust into goodwill trust and competence trust, and we explore the ways in which trust affects acceptance of NPPs through structural equation modeling. A survey of 491 people was conducted in Haiyan County, China, where the Qinshan nuclear power plant is located. We find that goodwill trust is significantly correlated with competence trust, and each can indirectly promote residents' acceptance of NPPs but by different paths. Goodwill trust improves acceptance of NPPs by decreasing risk perception, while competence trust improves acceptance of NPPs by increasing benefit perception. However, the associations between goodwill trust and benefit perception, competence trust and risk perception, are not significant. PMID- 29176853 TI - Age-related changes in oscillatory power affect motor action. AB - With increasing age cognitive performance slows down. This includes cognitive processes essential for motor performance. Additionally, performance of motor tasks becomes less accurate. The objective of the present study was to identify general neural correlates underlying age-related behavioral slowing and the reduction in motor task accuracy. To this end, we continuously recorded EEG activity from 18 younger and 24 older right-handed healthy participants while they were performing a simple finger tapping task. We analyzed the EEG records with respect to local changes in amplitude (power spectrum) as well as phase locking between the two age groups. We found differences between younger and older subjects in the amplitude of post-movement synchronization in the beta band of the sensory-motor and medial prefrontal cortex (mPFC). This post-movement beta amplitude was significantly reduced in older subjects. Moreover, it positively correlated with the accuracy with which subjects performed the motor task at the electrode FCz, which detects activity of the mPFC and the supplementary motor area. In contrast, we found no correlation between the accurate timing of local neural activity, i.e. phase locking in the delta-theta frequency band, with the reaction and movement time or the accuracy with which the motor task was performed. Our results show that only post-movement beta amplitude and not delta theta phase locking is involved in the control of movement accuracy. The decreased post-movement beta amplitude in the mPFC of older subjects hints at an impaired deactivation of this area, which may affect the cognitive control of stimulus-induced motor tasks and thereby motor output. PMID- 29176855 TI - Comparison of the external physical damages between laser-assisted and mechanical immobilized human sperm using scanning electronic microscopy. AB - We aim to visualize the external physical damages and distinct external phenotypic effects between mechanical and laser-assisted immobilized human spermatozoa using scanning electronic microscopy (SEM). Human spermatozoa were immobilized mechanically or with laser assistance for SEM examination and the membrane integrities were checked on both types of immobilized spermatozoa. We found evidence of external damages at SEM level on mechanically kinked sperm, but not on laser-assisted immobilized sperm. Although no external damage was found on laser-assist immobilized sperm, there were two distinct types of morphological changes when spermatozoa were stricken by infra-red laser. Coiled tails were immediately formed when Laser pulse was applied to the sperm end piece area, whereas laser applied to the sperm principal piece area resulted in a sharp bend of sperm tails. Sperm immobilized by laser did not exhibit any morphological change if the laser did not hit within the on-screen central target zone or if the laser hit the sperm mid piece or head. Our modified membrane integrity assay revealed that the external membrane of more than half of the laser-assisted immobilized sperm remained intact. In conclusion, mechanical immobilization produced membrane damages whilst laser-assisted immobilization did not result in any external membrane damages besides morphological changes at SEM level. PMID- 29176854 TI - Socioeconomic differential in self-assessment of health and happiness in 5 African countries: Finding from World Value Survey. AB - OBJECTIVE: Factors that contribute to wealth related inequalities in self-rated health (SRH) and happiness remains unclear most especially in sub-Saharan countries (SSA). This study aims to explore and compare socioeconomic differentials in SRH and happiness in five SSA countries. METHODS: Using the 2010/2014 World Values Survey (WVS), we obtained a sample of 9,869 participants of age 16 and above from five SSA countries (Nigeria, Ghana, South Africa, Rwanda and Zimbabwe). Socioeconomic inequalities were quantified using the concentration index. The contribution of each predictor to concentration index's magnitude was obtained by means of regression based decomposition analysis. RESULTS: Poor SRH ranges from approximately 9% in Nigeria to 20% in Zimbabwe, whereas unhappiness was lower in Rwanda (9.5%) and higher in South Africa (23.3%). Concentration index was negative for both outcomes in all countries, which implies that poor SRH and unhappiness are excessively concentrated among the poorest socioeconomic strata. Although magnitudes differ across countries, however, the major contributor to wealth-related inequality in poor SRH is satisfaction with financial situation whereas for unhappiness the major contributors are level of income and satisfaction with financial situation. CONCLUSIONS: This study underscores an association between wealth related inequalities and poor SRH and unhappiness in the context of SSA. Improving equity in health, as suggested by the commission of social determinants of health may be useful in fighting against the unfair distribution of resources. Thus, knowledge about the self-rating of health and happiness can serve as proxy estimates for understanding the distribution of health care access and economic resources needed for well-being in resident countries. PMID- 29176856 TI - Prenatal androgen-receptor activity has organizational morphological effects in mice. AB - Prenatal sex hormones exert organizational effects. It has been suggested that prenatal sex hormones affect adult morphological parameters, such as the finger length. Especially the second-to-fourth finger length (2D:4D) ratio has been implicated to be modified when exposed to higher androgen levels in utero. Here we show in a mouse model that experimental manipulation of the prenatal androgen level, by blocking the androgen receptor with flutamide or activating the androgen receptor with dihydrotestosterone (DHT), leads to changes in the length of the fingers of all paws in males and females. In addition to that, also total paw length and the 2D:4D ratio was affected. In males treated with DHT, the 2D:4D ratio was increased, while flutamide-treatment in females led to a reduced 2D:4D ratio. We also measured other parameters, such as head size, body length and tail length and demonstrate that body morphology is affected by prenatal androgen exposure with more prominent effects in females. Another factor that is thought to be influenced by early androgens is handedness. We tested mice for handedness, but did not find a significant effect of the prenatal treatment. These findings demonstrate that prenatal androgen activity is involved in the development of body morphology and might be a useful marker for prenatal androgen exposure. PMID- 29176857 TI - Prevalence of fimA genotypes of Porphyromonas gingivalis in adolescent orthodontic patients. AB - BACKGROUND: The placement of fixed orthodontic appliances may alter the composition of oral microbiota and has the potential risk of periodontal complication. Porphyromonas gingivalis fimbriae play a critical role in colonization of P. gingivalis in subgingival regions. In this study, we investigated the association between the prevalence of P. gingivalis-specific fimA genotypes and periodontal health status in adolescent orthodontic patients, to identify the pathogencity of P. gingivalis during orthodontic therapy. METHODS: Sixty-one adolescent orthodontic patients were enrolled in the case group, while the control group consisted of 56 periodontally healthy adolescents. At baseline (T0), clinical parameter (gingival index) was tested, and subgingival plaque samples were obtained from the lower incisors. The incidences of P. gingivalis and fimA genotypes were detected by polymerase chain reaction. All parameters were reassessed after 1 month (T1), 2 months (T2), 3 months (T3), and 6 months (T4) in the case group and then compared with those of the controls. RESULTS: Both microbiological and clinical parameters from orthodontic patients started to increase after placement of fixed appliances. Maximum values were reached at 3 months after placement and followed by their decreases at six months. However, the microbiological and clinical parameters in the case group were significantly higher than those of the control group. The GI of fimA II, IV positive samples was significantly higher than that of negative samples. CONCLUSION: P. gingivalis carrying fimA II or IV was closely related to orthodontic gingivitis. In addition, proper oral hygiene control could lead to little increase in dental plaque accumulation, and exert a beneficial effect to periodontal tissues. PMID- 29176858 TI - Sepsis-induced selective loss of NMDA receptors modulates hippocampal neuropathology in surviving septic mice. AB - BACKGROUND: Sepsis-induced neuroinflammation plays an important role in sepsis related brain dysfunction. However, the molecules that are targeted during neuroinflammation resulting from sepsis-induced brain dysfunction remain unclear. Herein, we tried to investigate the expression and roles of NMDA receptor subunits during sepsis-related brain dysfunction. METHODS: Sepsis was induced by cecal ligation and perforation (CLP) or by a single intraperitoneal injection of lipopolysaccharide (LPS, 8 mg/kg) in C57BL/6J mice. The NMDA receptor co-agonist D-serine was injected intraperitoneally for 3 days (500 mg/kg/day) to compensate for the loss of NMDA receptors. The behaviors of mice were tested in the Barnes maze and in the open field test. The mice were euthanized at the indicated time points. The brains were collected to detect the following: the levels of synaptophysin and NMDA receptor subunits GluN2A, GluN2B and GluN1 (by Western blot and RT-PCR); the number of CA1 neurons (by Nissl staining); neuronal activity (by p-CREB staining); neuroinflammation (by staining of Iba-1 and inflammatory factors IL-1beta, TNF-alpha, NLRP3); and the levels of oxidative stress [by dihydroethidium (DHE)]. RESULTS: Sepsis selectively decreased the protein and mRNA levels of GluN2A, GluN2B and GluN1 but not the levels of synaptophysin or the neuronal number in the hippocampus of mice in either of the classic CLP-induced or LPS-induced sepsis models during the first 7 days after sepsis. Intraperitoneal injection of D-serine obviously limited the lipopolysaccharide-induced changes, including the impairment of learning and memory, the loss of NMDA receptor subunits, robust neuroinflammation, the levels of ROS stress and the decrease of p-CREB in the hippocampus of mice. CONCLUSION: These data suggest that the sepsis-induced selective loss of NMDA receptors modulates hippocampal neuropathology in the mice that survived sepsis, and the data show that NMDA receptors are potential targets for the improvement of brain dysfunction in sepsis survivors. PMID- 29176859 TI - High efficiency cabin air filter in vehicles reduces drivers' roadway particulate matter exposures and associated lipid peroxidation. AB - Commuters who spend long hours on roads are exposed to high levels of traffic related air pollutants (TRAPs). Despite some well-known multiple adverse effects of TRAPs on human health, limited studies have focused on mitigation strategies to reduce these effects. In this study, we measured fine particulate matter (PM2.5) and ultrafine particle (UFP) concentrations inside and outside 17 taxis simultaneously while they were driven on roadways. The drivers' urinary monohydroxylated polycyclic aromatic hydrocarbons (OH-PAHs) and malondialdehyde (MDA) concentrations just before and right after the driving tests were also determined. Data were collected under three driving conditions (i.e. no mitigation (NM), window closed (WC), and window closed plus using high efficiency cabin air filters (WC+HECA)) for each taxi and driver. The results show that, compared to NM, the WC+HECA reduced in-cabin PM2.5 and UFP concentrations, by 37% and 47% respectively (p < 0.05), whereas the reductions on PAH exposures were insignificant. Although nonsignificant, a reduction of 17% was also observed in the drivers' urinary MDA under WC+HECA. The MDA concentrations were found to be significantly associated with the in-cabin PM2.5 and UFP concentrations, suggesting the reduction of the drivers' lipid peroxidation can be at least partially attributed to the PM2.5 and UFP reduction by WC+HECA. Overall, these results suggest HECA filters have potential to reduce particle levels inside taxis and protect drivers' health.

AB - The Pacific Equatorial dry forest of Northern Peru is recognised for its unique endemic biodiversity. Although highly threatened the forest provides livelihoods and ecosystem services to local communities. As agro-industrial expansion and climatic variation transform the region, close ecosystem monitoring is essential for viable adaptation strategies. UAVs offer an affordable alternative to satellites in obtaining both colour and near infrared imagery to meet the specific requirements of spatial and temporal resolution of a monitoring system. Combining this with their capacity to produce three dimensional models of the environment provides an invaluable tool for species level monitoring. Here we demonstrate that object-based image analysis of very high resolution UAV images can identify and quantify keystone tree species and their health across wide heterogeneous landscapes. The analysis exposes the state of the vegetation and serves as a baseline for monitoring and adaptive implementation of community based conservation and restoration in the area.

AB - BACKGROUND: The incidence of melanoma, particularly in older patients, has steadily increased over the past few decades. Activating mutations of BRAF, the majority occurring in BRAFV600, are frequently detected in melanoma; however, the prognostic significance remains unclear. This study aimed to define the probability and distribution of BRAFV600 mutations, and the clinico-pathological factors that may affect BRAF mutation status, in patients with advanced melanoma using next-generation sequencing. MATERIALS AND METHODS: This was a non interventional, retrospective study of BRAF mutation testing at two German centers, in Heidelberg and Tubingen. Archival tumor samples from patients with histologically confirmed melanoma (stage IIIB, IIIC, IV) were analyzed using PCR amplification and deep sequencing. Clinical, histological, and mutation data were collected. The statistical influence of patient- and tumor-related characteristics on BRAFV600 mutation status was assessed using multiple logistic regression (MLR) and a prediction profiler. RESULTS: BRAFV600 mutation status was assessed in 453 samples. Mutations were detected in 57.6% of patients (n = 261), with 48.1% (n = 102) at the Heidelberg site and 66.0% (n = 159) at the Tubingen site. The decreasing influence of increasing age on mutation probability was quantified. A main effects MLR model identified age (p = 0.0001), center (p = 0.0004), and melanoma subtype (p = 0.014) as significantly influencing BRAFV600 mutation probability; ultraviolet (UV) exposure showed a statistical trend (p = 0.1419). An interaction model of age versus other variables showed that center (p<0.0001) and melanoma subtype (p = 0.0038) significantly influenced BRAF mutation probability; age had a statistically significant effect only as part of an interaction with both UV exposure (p = 0.0110) and melanoma subtype (p = 0.0134). CONCLUSIONS: This exploratory study highlights that testing center, melanoma subtype, and age in combination with UV exposure and melanoma subtype significantly influence BRAFV600 mutation probability in patients with melanoma. Further validation of this model, in terms of reproducibility and broader relevance, is required. PMID- 29176862 TI - Plant-type phytoene desaturase: Functional evaluation of structural implications. AB - Phytoene desaturase (PDS) is an essential plant carotenoid biosynthetic enzyme and a prominent target of certain inhibitors, such as norflurazon, acting as bleaching herbicides. PDS catalyzes the introduction of two double bonds into 15 cis-phytoene, yielding 9,15,9'-tri-cis-zeta-carotene via the intermediate 9,15-di cis-phytofluene. We present the necessary data to scrutinize functional implications inferred from the recently resolved crystal structure of Oryza sativa PDS in a complex with norflurazon. Using dynamic mathematical modeling of reaction time courses, we support the relevance of homotetrameric assembly of the enzyme observed in crystallo by providing evidence for substrate channeling of the intermediate phytofluene between individual subunits at membrane surfaces. Kinetic investigations are compatible with an ordered ping-pong bi-bi kinetic mechanism in which the carotene and the quinone electron acceptor successively occupy the same catalytic site. The mutagenesis of a conserved arginine that forms a hydrogen bond with norflurazon, the latter competing with plastoquinone, corroborates the possibility of engineering herbicide resistance, however, at the expense of diminished catalytic activity. This mutagenesis also supports a "flavin only" mechanism of carotene desaturation not requiring charged residues in the active site. Evidence for the role of the central 15-cis double bond of phytoene in determining regio-specificity of carotene desaturation is presented. PMID- 29176863 TI - Life events and hopelessness depression: The influence of affective experience. AB - This study explored the association of the affective experience (AE) of life events on hopelessness depression (HD). Undergraduates (N = 301) participating in a 12-week prospective study completed measures of HD, cognitive style, and psychological stress. The results indicate AE is an underlying mechanism influencing the longitudinal link between life events and HD. Negative life events with clear negative AE directly promoted the development of HD. Positive life events with clear positive AE directly impeded the development of HD. Neutral life events with mixed AE directly and interacting with negative cognitive style promoted the development of HD. The results should increase understanding of the hopelessness theory of depression, and suggest that neutral life events should be important elements in depression therapy. PMID- 29176864 TI - Health assessment of French university students and risk factors associated with mental health disorders. AB - OBJECTIVE: The first year of university is a particularly stressful period and can impact academic performance and students' health. The aim of this study was to evaluate the health and lifestyle of undergraduates and assess risk factors associated with psychiatric symptoms. MATERIALS AND METHODS: Between September 2012 and June 2013, we included all undergraduate students who underwent compulsory a medical visit at the university medical service in Nice (France) during which they were screened for potential diseases during a diagnostic interview. Data were collected prospectively in the CALCIUM database (Consultations Assistes par Logiciel pour les Centres Inter-Universitaire de Medecine) and included information about the students' lifestyle (living conditions, dietary behavior, physical activity, use of recreational drugs). The prevalence of psychiatric symptoms related to depression, anxiety and panic attacks was assessed and risk factors for these symptoms were analyzed using logistic regression. RESULTS: A total of 4,184 undergraduates were included. Prevalence for depression, anxiety and panic attacks were 12.6%, 7.6% and 1.0%, respectively. During the 30 days preceding the evaluation, 0.6% of the students regularly drank alcohol, 6.3% were frequent-to-heavy tobacco smokers, and 10.0% smoked marijuana. Dealing with financial difficulties and having learning disabilities were associated with psychiatric symptoms. Students who were dissatisfied with their living conditions and those with poor dietary behavior were at risk of depression. Being a woman and living alone were associated with anxiety. Students who screened positively for any psychiatric disorder assessed were at a higher risk of having another psychiatric disorder concomitantly. CONCLUSION: The prevalence of psychiatric disorders in undergraduate students is low but the rate of students at risk of developing chronic disease is far from being negligible. Understanding predictors for these symptoms may improve students' health by implementing targeted prevention campaigns. Further research in other French universities is necessary to confirm our results. PMID- 29176865 TI - Pre-clinical antigenicity studies of an innovative multivalent vaccine for human visceral leishmaniasis. AB - The notion that previous infection by Leishmania spp. in endemic areas leads to robust anti-Leishmania immunity, supports vaccination as a potentially effective approach to prevent disease development. Nevertheless, to date there is no vaccine available for human leishmaniasis. We optimized and assessed in vivo the safety and immunogenicity of an innovative vaccine candidate against human visceral leishmaniasis (VL), consisting of Virus-Like Particles (VLP) loaded with three different recombinant proteins (LJL143 from Lutzomyia longipalpis saliva as the vector-derived (VD) component, and KMP11 and LeishF3+, as parasite-derived (PD) antigens) and adjuvanted with GLA-SE, a TLR4 agonist. No apparent adverse reactions were observed during the experimental time-frame, which together with the normal hematological parameters detected seems to point to the safety of the formulation. Furthermore, measurements of antigen-specific cellular and humoral responses, generally higher in immunized versus control groups, confirmed the immunogenicity of the vaccine formulation. Interestingly, the immune responses against the VD protein were reproducibly more robust than those elicited against leishmanial antigens, and were apparently not caused by immunodominance of the VD antigen. Remarkably, priming with the VD protein alone and boosting with the complete vaccine candidate contributed towards an increase of the immune responses to the PD antigens, assessed in the form of increased ex vivo CD4+ and CD8+ T cell proliferation against both the PD antigens and total Leishmania antigen (TLA). Overall, our immunogenicity data indicate that this innovative vaccine formulation represents a promising anti-Leishmania vaccine whose efficacy deserves to be tested in the context of the "natural infection". PMID- 29176866 TI - Quercetin metabolism by fecal microbiota from healthy elderly human subjects. AB - Quercetin is a polyphenol found in food that has numerous health benefits. This study investigated the relationship between quercetin metabolism, gut microbiota composition, and dietary intake in elderly Japanese subjects. A food frequency questionnaire was used to assess dietary intake during the week prior to stool sample collection. Fecal suspensions from 56 subjects were anaerobically incubated with quercetin and fecal microbiota composition was analyzed by next generation sequencing. Inter-individual variations in quercetin concentration and fecal microbiota composition at family level suggested differences in microbial quercetin metabolism. The abundance of Sutterellaceae (r = -0.292) and Oscillospiraceae (r = -0.334) was negatively correlated whereas that of Fusobacteriaceae (r = 0.361) and Enterobacteriaceae (r = 0.321) was positively correlated with quercetin concentration. Niacin (r = -0.313), vitamin B6 (r = 0.297), vitamin B12 (r = -0.266), vitamin D (r = -0.301), and ratio of animal protein to total protein (r = -0.27) were also negatively correlated with quercetin concentration. Bacterial abundance was positively or negatively related to intake of food components. This is the first report describing the relationship between fecal quercetin metabolism, human microbiota, and dietary intake in the elderly. PMID- 29176867 TI - Application of non-Gaussian water diffusional kurtosis imaging in the assessment of uterine tumors: A preliminary study. AB - OBJECTIVES: To evaluate the interobserver reliability and value of diffusional kurtosis imaging (DKI) in the assessment of uterine tumors compared with those of conventional diffusion-weighted imaging (DWI). METHODS: This retrospective study was approved by our institutional review board, which waived the requirement for informed consent. Fifty-eight women (mean age: 55.0 +/- 13.6 years; range: 30-89 years) with suspected malignant uterine tumors underwent 3-T magnetic resonance imaging using DKI and DWI. Twelve had coexisting leiomyoma. Two observers analyzed region-of-interest measurements of diffusivity (D), kurtosis (K), and the apparent diffusion coefficient (ADC) of uterine lesions and healthy adjacent tissues. Interobserver agreement was evaluated using the intra-class correlation coefficient (ICC). The mean values were compared using one-way analysis of variance with a post-hoc Tukey's honestly significant difference test. The diagnostic accuracy of D and ADC in differentiating malignant tumors from benign leiomyomas was analyzed using receiver operating characteristic (ROC) analysis. RESULTS: The ICCs between the two observers in evaluating D, K, and the ADC of the malignant tumors were higher than 0.84, suggesting excellent interobserver agreements. The mean D (*10-3 mm2/s) of uterine cancers (1.05 +/- 0.41 and 1.09 +/- 0.40 for observers 1 and 2, respectively) were significantly lower than those of leiomyoma (1.40 +/- 0.37 and 1.56 +/- 0.33, respectively; P < 0.05), healthy myometrium (1.72 +/- 0.27 and 1.69 +/- 0.30, respectively; P < 0.001), and healthy endometrium (1.53 +/- 0.35 and 1.42 +/- 0.37, respectively; P < 0.005). There was no significant difference in the area under the ROC curve between D and ADC. The mean K of uterine cancers (0.88 +/- 0.28 and 0.90 +/- 0.23, respectively) were higher than those of myometrium (0.72 +/- 0.10 and 0.73 +/- 0.10, respectively; P < 0.001), healthy endometrium (0.65 +/- 0.13 and 0.60 +/- 0.18, respectively; P < 0.001), and leiomyoma (0.76 +/- 0.14 and 0.77 +/- 0.16, respectively; not significant, P > 0.1). CONCLUSIONS: Interobserver agreements in evaluating D, K, and ADC were moderate to excellent. D performed equally to conventional DWI in differentiating between benign and malignant uterine lesions. The mean K of malignant uterine lesions was significantly higher than that of non tumorous myometrium or endometrium. PMID- 29176868 TI - A century of changing flows: Forest management changed flow magnitudes and warming advanced the timing of flow in a southwestern US river. AB - The continued provision of water from rivers in the southwestern United States to downstream cities, natural communities and species is at risk due to higher temperatures and drought conditions in recent decades. Snowpack and snowfall levels have declined, snowmelt and peak spring flows are arriving earlier, and summer flows have declined. Concurrent to climate change and variation, a century of fire suppression has resulted in dramatic changes to forest conditions, and yet, few studies have focused on determining the degree to which changing forests have altered flows. In this study, we evaluated changes in flow, climate, and forest conditions in the Salt River in central Arizona from 1914-2012 to compare and evaluate the effects of changing forest conditions and temperatures on flows. After using linear regression models to remove the influence of precipitation and temperature, we estimated that annual flows declined by 8-29% from 1914-1963, coincident with a 2-fold increase in basal area, a 2-3-fold increase in canopy cover, and at least a 10-fold increase in forest density within ponderosa pine forests. Streamflow volumes declined by 37-56% in summer and fall months during this period. Declines in climate-adjusted flows reversed at mid-century when spring and annual flows increased by 10-31% from 1964-2012, perhaps due to more winter rainfall. Additionally, peak spring flows occurred about 12 days earlier in this period than in the previous period, coincident with winter and spring temperatures that increased by 1-2 degrees C. While uncertainties remain, this study adds to the knowledge gained in other regions that forest change has had effects on flow that were on par with climate variability and, in the case of mid century declines, well before the influence of anthropogenic warming. Current large-scale forest restoration projects hold some promise of recovering seasonal flows. PMID- 29176869 TI - Successful transplantation of porcine liver grafts following 48-hour normothermic preservation. AB - Current cold storage organ preservation technique fails to preserve marginal donor grafts sufficiently. Evidence from large animal experiments suggests superiority of normothermic machine preservation of liver allografts. Long-term organ preservation using normothermic perfusion might not only allow organ viability assessment before transplantation, but also provide the means for further organ modifications under physiologic conditions. Previous research has shown that porcine livers can be transplanted successfully after normothermic preservation of 20 hours. In the present study we investigate whether similar methodology is capable of further extending the safe limit to 48 hours. In this study, livers from White Landrace pigs were preserved by normothermic, oxygenated sanguineous perfusion. After a 48-hour period of preservation, livers were transplanted into recipient pigs and followed for 5 days. Outcome parameters measured included markers of synthetic and metabolic liver function as well as hepatocellular injury and blood gas analysis during perfusion and follow-up. Histological assessment of morphological liver integrity was performed. All livers showed sustained bile production and metabolic activity throughout the preservation period. Low levels of hepatocellular damage were found. Following transplantation all liver grafts revealed excellent graft function and death censored graft survival was 100%. Porcine livers were transplanted successfully following 48 hours normothermic machine preservation. PMID- 29176870 TI - Molecular cloning, in-silico characterization and functional validation of monodehydroascorbate reductase gene in Eleusine coracana. AB - Ascorbic acid is a ubiquitous water soluble antioxidant that plays a critical role in plant growth and environmental stress tolerance. It acts as a free radical scavenger as well as a source of reducing power for several cellular processes. Because of its pivotal role in regulating plant growth under optimal as well as sub-optimal conditions, it becomes obligatory for plants to maintain a pool of reduced ascorbic acid. Several cellular processes help in maintaining the reduced ascorbic acid pool, by regulating its synthesis and regeneration processes. Current study demonstrates that monodehydroascorbate reductase is an important enzyme responsible for maintaining the reduced ascorbate pool, by optimizing the recycling of oxidized ascorbate. Cloning and functional characterization of this important stress inducible gene is of great significance for its imperative use in plant stress management. Therefore, we have cloned and functionally validated the role of monodehydroascorbate reductase gene (mdar) from a drought tolerant variety of Eleusine coracana. The cloned Ecmdar gene comprises of 1437bp CDS, encoding a 478 amino acid long polypeptide. The active site analysis showed presence of conserved Tyr348 residue, facilitating the catalytic activity in electron transfer mechanism. qPCR expression profiling of Ecmdar under stress indicated that it is an early responsive gene. The analysis of Ecmdar overexpressing Arabidopsis transgenic lines suggests that monodehydroascorbate reductase acts as a key stress regulator by modulating the activity of antioxidant enzymes to strengthen the ROS scavenging ability and maintains ROS homeostasis. Thus, it is evident that Ecmdar is an important gene for cellular homeostasis and its over-expression could be successfully used to strengthen stress tolerance in crop plants. PMID- 29176871 TI - Effect of radiotherapy on activity and concentration of serum paraoxonase-1 in breast cancer patients. AB - Paraoxonase-1 (PON1) is an intra-cellular antioxidant enzyme found also in the circulation associated with high-density lipoproteins. The activity of this enzyme has been shown to be decreased in breast cancer (BC) patients. The aims of our study were to investigate the changes produced by radiotherapy (RT) on activity and concentration of serum PON1 in BC patients, and to evaluate the observed variations in relation to clinical and pathological characteristics of patients and tumors, and the response to treatment. We studied 200 women with BC who were scheduled to receive RT following excision of the tumor. Blood for analyses was obtained before and after the irradiation procedure. The control group was composed of 200 healthy women. Relative to control, BC patients had significantly lower serum PON1 activities pre-RT, while PON1 concentrations were at similar levels. RT was associated with a significant increase in serum PON1 activities and concentrations. We observed significant differences in serum PON1 concentrations post-RT between patients with luminal A or luminal B tumors. Serum PON1 concentration post-RT was markedly lower in BC patients with metastases. We conclude that benefit from RT accrues to the BC patients not only through its direct effect on cancer cells but also indirectly by improving the organism's anti-oxidant defense mechanisms. In addition, our preliminary evidence suggests that the measurement of serum PON1 concentration post-RT could be an efficient prognostic biomarker, and may be used as an index of the efficacy of the RT. PMID- 29176873 TI - Objective measurement of subjective tinnitus using the acoustic change complex. AB - At present, there is no objective method for diagnosing subjective sensorineural tinnitus. Recently, the acoustic change complex (ACC) has been used to evaluate neural detection of sounds. Thus, the present study aimed to examine whether the ACC can reflect cortical detection and discrimination of sounds matched with tinnitus frequencies. We hypothesized that the ACC to change stimuli matched with tinnitus frequencies would be decreased in tinnitus patients because the tinnitus interferes with the perception of acoustic changes. To test the hypothesis, 96 ears of normal-hearing (NH) tinnitus patients and controls were tested. Among the tinnitus patients, 33 ears with a tinnitus frequency of 8 kHz constituted the tinnitus group, and the remaining 63 ears with no experience of tinnitus were allocated to the control group. For the 4 kHz non-tinnitus matched frequency, a subset of tinnitus (n = 17) and NH (n = 47) subjects was tested. The acoustic stimuli were pure tones with a total duration of 500 ms consisting of a 1 kHz tone in the first 250 ms and a second tone of either 8 kHz or 4 kHz in the latter 250 ms. The normalized amplitude of the ACC (naACC) was calculated separately for the amplitude of the N1'-P2' complex evoked by an 8 kHz or 4 kHz change stimulus and for the amplitude of the N1-P2 complex elicited by the initial 1 kHz background stimulus. Our results showed that the naACC to an 8 kHz stimulus in the tinnitus group was significantly smaller than those to 4 kHz and 8 kHz in normal controls. Additionally, in the tinnitus group, the naACC to 4 kHz was greater compared to 8 kHz. The receiver operating characteristic (ROC) curve analysis conducted for naACC to 8 kHz at UCL revealed a fair degree of diagnostic efficacy. Overall, our results indicated that the ACC to a change stimulus matched with the tinnitus frequency can provide an objective measure of frequency specific tinnitus. PMID- 29176872 TI - Para-hydroxyphenylpyruvate inhibits the pro-inflammatory stimulation of macrophage preventing LPS-mediated nitro-oxidative unbalance and immunometabolic shift. AB - Targeting metabolism is emerging as a promising therapeutic strategy for modulation of the immune response in human diseases. In the presented study we used the lipopolysaccharide (LPS)-mediated activation of RAW 264.7 macrophage like cell line as a model to investigate changes in the metabolic phenotype and to test the effect of p-hydroxyphenylpyruvate (pHPP) on it. pHPP is an intermediate of the PHE/TYR catabolic pathway, selected as analogue of the ethyl pyruvate (EP), which proved to exhibit antioxidant and anti-inflammatory activities. The results obtained show that LPS-priming of RAW 264.7 cell line to the activated M1 state resulted in up-regulation of the inducible nitric oxide synthase (iNOS) expression and consequently of NO production and in release of the pro-inflammatory cytokine IL-6. All these effects were prevented dose dependently by mM concentrations of pHPP more efficiently than EP. Respirometric and metabolic flux analysis of LPS-treated RAW 264.7 cells unveiled a marked metabolic shift consisting in downregulation of the mitochondrial oxidative phosphorylation and upregulation of aerobic glycolysis respectively. The observed respiratory failure in LPS-treated cells was accompanied with inhibition of the respiratory chain complexes I and IV and enhanced production of reactive oxygen species. Inhibition of the respiratory activity was also observed following incubation of human neonatal fibroblasts (NHDF-neo) with sera from septic patients. pHPP prevented all the observed metabolic alteration caused by LPS on RAW 264.7 or by septic sera on NHDF-neo. Moreover, we provide evidence that pHPP is an efficient reductant of cytochrome c. On the basis of the presented results a working model, linking pathogen-associated molecular patterns (PAMPs)-mediated immune response to mitochondrial oxidative metabolism, is put forward along with suggestions for its therapeutic control. PMID- 29176874 TI - Neurturin overexpression in dopaminergic neurons induces presynaptic and postsynaptic structural changes in rats with chronic 6-hydroxydopamine lesion. AB - The structural effect of neurturin (NRTN) on the nigrostriatal dopaminergic system in animals remains unknown, although NRTN has been shown to be effective in Parkinson's disease animal models. Herein, we aimed to demonstrate that NRTN overexpression in dopaminergic neurons stimulates both neurite outgrowths in the nigrostriatal pathway and striatal dendritic spines in aging rats with chronic 6 hydroxydopamine (6-OHDA) lesion. At week 12 after lesion, pTracer-mNRTN-His or pGreenLantern-1 plasmids were intranigrally transfected using the NTS-polyplex nanoparticles system. We showed that the transgenic expression in dopaminergic neurons remained until the end of the study (12 weeks). Only animals expressing NRTN-His showed recovery of tyrosine hydroxylase (TH)+ cells (28 +/- 2%), their neurites (32 +/- 2%) and the neuron-specific cytoskeletal marker beta-III-tubulin in the substantia nigra; striatal TH(+) fibers were also recovered (52 +/- 3%), when compared to the healthy condition. Neurotensin receptor type 1 levels were also significantly recovered in the substantia nigra and striatum. Dopamine recovery was 70 +/- 4% in the striatum and complete in the substantia nigra. The number of dendritic spines of striatal medium spiny neurons was also significantly increased, but the recovery was not complete. Drug-activated circling behavior decreased by 73 +/- 2% (methamphetamine) and 89 +/- 1% (apomorphine). Similar decrease was observed in the spontaneous motor behavior. Our results demonstrate that NRTN causes presynaptic and postsynaptic restoration of the nigrostriatal dopaminergic system after a 6-OHDA-induced chronic lesion. However, those improvements did not reach the healthy condition, suggesting that NRTN exerts lesser neurotrophic effects than other neurotrophic approaches. PMID- 29176875 TI - The orientation of homing pigeons (Columba livia f.d.) with and without navigational experience in a two-dimensional environment. AB - Homing pigeons are known for their excellent homing ability, and their brains seem to be functionally adapted to homing. It is known that pigeons with navigational experience show a larger hippocampus and also a more lateralised brain than pigeons without navigational experience. So we hypothesized that experience may have an influence also on orientation ability. We examined two groups of pigeons (11 with navigational experience and 17 without) in a standard operant chamber with a touch screen monitor showing a 2-D schematic of a rectangular environment (as "geometric" information) and one uniquely shaped and colored feature in each corner (as "landmark" information). Pigeons were trained first for pecking on one of these features and then we examined their ability to encode geometric and landmark information in four tests by modifying the rectangular environment. All tests were done under binocular and monocular viewing to test hemispheric dominance. The number of pecks was counted for analysis. Results show that generally both groups orientate on the basis of landmarks and the geometry of environment, but landmark information was preferred. Pigeons with navigational experience did not perform better on the tests but showed a better conjunction of the different kinds of information. Significant differences between monocular and binocular viewing were detected particularly in pigeons without navigational experience on two tests with reduced information. Our data suggest that the conjunction of geometric and landmark information might be integrated after processing separately in each hemisphere and that this process is influenced by experience. PMID- 29176876 TI - Neuroprotection and neuroregeneration of retinal ganglion cells after intravitreal carbon monoxide release. AB - PURPOSE: Retinal ischemia induces apoptosis leading to neurodegeneration and vision impairment. Carbon monoxide (CO) in gaseous form showed cell-protective and anti-inflammatory effects after retinal ischemia-reperfusion-injury (IRI). These effects were also demonstrated for the intravenously administered CO releasing molecule (CORM) ALF-186. This article summarizes the results of intravitreally released CO to assess its suitability as a neuroprotective and neuroregenerative agent. METHODS: Water-soluble CORM ALF-186 (25 MUg), PBS, or inactivated ALF (iALF) (all 5 MUl) were intravitreally applied into the left eyes of rats directly after retinal IRI for 1 h. Their right eyes remained unaffected and were used for comparison. Retinal tissue was harvested 24 h after intervention to analyze mRNA or protein expression of Caspase-3, pERK1/2, p38, HSP70/90, NF-kappaB, AIF-1 (allograft inflammatory factor), TNF-alpha, and GAP 43. Densities of fluorogold-prelabeled retinal ganglion cells (RGC) were examined in flat-mounted retinae seven days after IRI and were expressed as mean/mm2. The ability of RGC to regenerate their axon was evaluated two and seven days after IRI using retinal explants in laminin-1-coated cultures. Immunohistochemistry was used to analyze the different cell types growing out of the retinal explants. RESULTS: Compared to the RGC-density in the contralateral right eyes (2804+/-214 RGC/mm2; data are mean+/-SD), IRI+PBS injection resulted in a remarkable loss of RGC (1554+/-159 RGC/mm2), p<0.001. Intravitreally injected ALF-186 immediately after IRI provided RGC protection and reduced the extent of RGC-damage (IRI+PBS 1554+/-159 vs. IRI+ALF 2179+/-286, p<0.001). ALF-186 increased the IRI-mediated phosphorylation of MAP-kinase p38. Anti-apoptotic and anti-inflammatory effects were detectable as Caspase-3, NF-kappaB, TNF-alpha, and AIF-1 expression were significantly reduced after IRI+ALF in comparison to IRI+PBS or IRI+iALF. Gap-43 expression was significantly increased after IRI+ALF. iALF showed effects similar to PBS. The intrinsic regenerative potential of RGC-axons was induced to nearly identical levels after IRI and ALF or iALF-treatment under growth-permissive conditions, although RGC viability differed significantly in both groups. Intravitreal CO further increased the IRI-induced migration of GFAP-positive cells out of retinal explants and their transdifferentiation, which was detected by re-expression of beta-III tubulin and nestin. CONCLUSION: Intravitreal CORM ALF-186 protected RGC after IRI and stimulated their axons to regenerate in vitro. ALF conveyed anti-apoptotic, anti-inflammatory, and growth-associated signaling after IRI. CO's role in neuroregeneration and its effect on retinal glial cells needs further investigation. PMID- 29176877 TI - Rv0004 is a new essential member of the mycobacterial DNA replication machinery. AB - DNA replication is fundamental for life, yet a detailed understanding of bacterial DNA replication is limited outside the organisms Escherichia coli and Bacillus subtilis. Many bacteria, including mycobacteria, encode no identified homologs of helicase loaders or regulators of the initiator protein DnaA, despite these factors being essential for DNA replication in E. coli and B. subtilis. In this study we discover that a previously uncharacterized protein, Rv0004, from the human pathogen Mycobacterium tuberculosis is essential for bacterial viability and that depletion of Rv0004 leads to a block in cell cycle progression. Using a combination of genetic and biochemical approaches, we found that Rv0004 has a role in DNA replication, interacts with DNA and the replicative helicase DnaB, and affects DnaB-DnaA complex formation. We also identify a conserved domain in Rv0004 that is predicted to structurally resemble the N terminal protein-protein interaction domain of DnaA. Mutation of a single conserved tryptophan within Rv0004's DnaA N-terminal-like domain leads to phenotypes similar to those observed upon Rv0004 depletion and can affect the association of Rv0004 with DnaB. In addition, using live cell imaging during depletion of Rv0004, we have uncovered a previously unappreciated role for DNA replication in coordinating mycobacterial cell division and cell size. Together, our data support that Rv0004 encodes a homolog of the recently identified DciA family of proteins found in most bacteria that lack the DnaC-DnaI helicase loaders in E. coli and B. subtilis. Therefore, the mechanisms of Rv0004 elucidated here likely apply to other DciA homologs and reveal insight into the diversity of bacterial strategies in even the most conserved biological processes. PMID- 29176878 TI - Genome-wide recombination rate variation in a recombination map of cotton. AB - Recombination is crucial for genetic evolution, which not only provides new allele combinations but also influences the biological evolution and efficacy of natural selection. However, recombination variation is not well understood outside of the complex species' genomes, and it is particularly unclear in Gossypium. Cotton is the most important natural fibre crop and the second largest oil-seed crop. Here, we found that the genetic and physical maps distances did not have a simple linear relationship. Recombination rates were unevenly distributed throughout the cotton genome, which showed marked changes along the chromosome lengths and recombination was completely suppressed in the centromeric regions. Recombination rates significantly varied between A-subgenome (At) (range = 1.60 to 3.26 centimorgan/megabase [cM/Mb]) and D-subgenome (Dt) (range = 2.17 to 4.97 cM/Mb), which explained why the genetic maps of At and Dt are similar but the physical map of Dt is only half that of At. The translocation regions between A02 and A03 and between A04 and A05, and the inversion regions on A10, D10, A07 and D07 indicated relatively high recombination rates in the distal regions of the chromosomes. Recombination rates were positively correlated with the densities of genes, markers and the distance from the centromere, and negatively correlated with transposable elements (TEs). The gene ontology (GO) categories showed that genes in high recombination regions may tend to response to environmental stimuli, and genes in low recombination regions are related to mitosis and meiosis, which suggested that they may provide the primary driving force in adaptive evolution and assure the stability of basic cell cycle in a rapidly changing environment. Global knowledge of recombination rates will facilitate genetics and breeding in cotton.

AB - OBJECTIVE: This study aims to examine the patterns and socio-demographic predictors of health and environmental co-benefit behaviours that support climate change mitigation in a densely populated Asian metropolis-Hong Kong. METHODS: A population-based, stratified and cross-sectional random digit dialling telephone survey study was conducted between January and February 2016, among the Cantonese speaking population aged 15 and above in Hong Kong. Socio-demographic data and the self-reported practice of 10 different co-benefit behaviours were solicited. Ethics approval and participant's verbal consent were sought. FINDINGS: The study sample consisted of 1,017 respondents (response rate: 63.6%) were comparable to the age, gender and geographical distributions of the Hong Kong population found in the latest 2011 Hong Kong Population Census. Among the co-benefit behaviours, using less packaging and disposable shopping bags were practiced in the highest frequency (70.1%). However, four behaviours were found to have never been practiced by more than half of the respondents, including bringing personal eating utensils when dining in restaurants or small eateries, showering less than five minutes, having one vegetarian meal a week, and buying more organic food. Results of multivariable logistic regression showed that frequency of practicing co-benefit behaviours were consistently associated with gender and age. CONCLUSION: Urban residents in Hong Kong do not engage in the practice of co benefit behaviours in a uniform way. In general, females and older people are more likely to adopt co-benefit behaviours in their daily lives. Further research to assess the knowledge and attitudes of the population towards these co-benefit behaviours will provide support to relevant climate change mitigation policies and education programmes. PMID- 29176880 TI - Seroprevalence of rickettsial infections and Q fever in Bhutan. AB - BACKGROUND: With few studies conducted to date, very little is known about the epidemiology of rickettsioses in Bhutan. Due to two previous outbreaks and increasing clinical cases, scrub typhus is better recognized than other rickettsial infections and Q fever. METHODOLOGY: A descriptive cross-sectional serosurvey was conducted from January to March 2015 in eight districts of Bhutan. Participants were 864 healthy individuals from an urban (30%) and a rural (70%) sampling unit in each of the eight districts. Serum samples were tested by microimmunofluorescence assay for rickettsial antibodies at the Australian Rickettsial Reference Laboratory. RESULTS: Of the 864 participants, 345 (39.9%) were males and the mean age of participants was 41.1 (range 13-98) years. An overall seroprevalence of 49% against rickettsioses was detected. Seroprevalence was highest against scrub typhus group (STG) (22.6%) followed by spotted fever group (SFG) rickettsia (15.7%), Q fever (QF) (6.9%) and typhus group (TG) rickettsia (3.5%). Evidence of exposure to multiple agents was also noted; the commonest being dual exposure to STG and SFG at 5%. A person's likelihood of exposure to STG and SFG rickettsia significantly increased with age and farmers were twice as likely to have evidence of STG exposure as other occupations. Trongsa district appeared to be a hotspot for STG exposure while Punakha district had the lowest STG exposure risk. Zhemgang had the lowest exposure risk to SFG rickettsia compared to other districts. People living at altitudes above 2000 meters were relatively protected from STG infections but this was not observed for SFG, TG or QF exposure. CONCLUSION: This seroprevalence study highlights the endemicity of STG and SFG rickettsia in Bhutan. The high seroprevalence warrants appropriate public health interventions, such as diagnostic improvements and clinical treatment guidelines. Future studies should focus on vector profiles, geospatial, bio-social and environmental risk assessment and preventive and control strategies. PMID- 29176881 TI - A novel registration-based methodology for prediction of trabecular bone fabric from clinical QCT: A comprehensive analysis. AB - Osteoporosis leads to hip fractures in aging populations and is diagnosed by modern medical imaging techniques such as quantitative computed tomography (QCT). Hip fracture sites involve trabecular bone, whose strength is determined by volume fraction and orientation, known as fabric. However, bone fabric cannot be reliably assessed in clinical QCT images of proximal femur. Accordingly, we propose a novel registration-based estimation of bone fabric designed to preserve tensor properties of bone fabric and to map bone fabric by a global and local decomposition of the gradient of a non-rigid image registration transformation. Furthermore, no comprehensive analysis on the critical components of this methodology has been previously conducted. Hence, the aim of this work was to identify the best registration-based strategy to assign bone fabric to the QCT image of a patient's proximal femur. The normalized correlation coefficient and curvature-based regularization were used for image-based registration and the Frobenius norm of the stretch tensor of the local gradient was selected to quantify the distance among the proximal femora in the population. Based on this distance, closest, farthest and mean femora with a distinction of sex were chosen as alternative atlases to evaluate their influence on bone fabric prediction. Second, we analyzed different tensor mapping schemes for bone fabric prediction: identity, rotation-only, rotation and stretch tensor. Third, we investigated the use of a population average fabric atlas. A leave one out (LOO) evaluation study was performed with a dual QCT and HR-pQCT database of 36 pairs of human femora. The quality of the fabric prediction was assessed with three metrics, the tensor norm (TN) error, the degree of anisotropy (DA) error and the angular deviation of the principal tensor direction (PTD). The closest femur atlas (CTP) with a full rotation (CR) for fabric mapping delivered the best results with a TN error of 7.3 +/- 0.9%, a DA error of 6.6 +/- 1.3% and a PTD error of 25 +/- 2 degrees . The closest to the population mean femur atlas (MTP) using the same mapping scheme yielded only slightly higher errors than CTP for substantially less computing efforts. The population average fabric atlas yielded substantially higher errors than the MTP with the CR mapping scheme. Accounting for sex did not bring any significant improvements. The identified fabric mapping methodology will be exploited in patient-specific QCT-based finite element analysis of the proximal femur to improve the prediction of hip fracture risk. PMID- 29176882 TI - Mechanisms of action of Coxiella burnetii effectors inferred from host-pathogen protein interactions. AB - Coxiella burnetii is an obligate Gram-negative intracellular pathogen and the etiological agent of Q fever. Successful infection requires a functional Type IV secretion system, which translocates more than 100 effector proteins into the host cytosol to establish the infection, restructure the intracellular host environment, and create a parasitophorous vacuole where the replicating bacteria reside. We used yeast two-hybrid (Y2H) screening of 33 selected C. burnetii effectors against whole genome human and murine proteome libraries to generate a map of potential host-pathogen protein-protein interactions (PPIs). We detected 273 unique interactions between 20 pathogen and 247 human proteins, and 157 between 17 pathogen and 137 murine proteins. We used orthology to combine the data and create a single host-pathogen interaction network containing 415 unique interactions between 25 C. burnetii and 363 human proteins. We further performed complementary pairwise Y2H testing of 43 out of 91 C. burnetii-human interactions involving five pathogen proteins. We used the combined data to 1) perform enrichment analyses of target host cellular processes and pathways, 2) examine effectors with known infection phenotypes, and 3) infer potential mechanisms of action for four effectors with uncharacterized functions. The host-pathogen interaction profiles supported known Coxiella phenotypes, such as adapting cell morphology through cytoskeletal re-arrangements, protein processing and trafficking, organelle generation, cholesterol processing, innate immune modulation, and interactions with the ubiquitin and proteasome pathways. The generated dataset of PPIs-the largest collection of unbiased Coxiella host pathogen interactions to date-represents a rich source of information with respect to secreted pathogen effector proteins and their interactions with human host proteins. PMID- 29176883 TI - Wnt co-receptors Lrp5 and Lrp6 differentially mediate Wnt3a signaling in osteoblasts. AB - Wnt3a is a major regulator of bone metabolism however, very few of its target genes are known in bone. Wnt3a preferentially signals through transmembrane receptors Frizzled and co-receptors Lrp5/6 to activate the canonical signaling pathway. Previous studies have shown that the canonical Wnt co-receptors Lrp5 and Lrp6 also play an essential role in normal postnatal bone homeostasis, yet, very little is known about specific contributions by these co-receptors in Wnt3a dependent signaling. We used high-throughput sequencing technology to identify target genes regulated by Wnt3a in osteoblasts and to elucidate the role of Lrp5 and Lrp6 in mediating Wnt3a signaling. Our study identified 782 genes regulated by Wnt3a in primary calvarial osteoblasts. Wnt3a up-regulated the expression of several key regulators of osteoblast proliferation/ early stages of differentiation while inhibiting genes expressed in later stages of osteoblastogenesis. We also found that Lrp6 is the key mediator of Wnt3a signaling in osteoblasts and Lrp5 played a less significant role in mediating Wnt3a signaling. PMID- 29176884 TI - Alcohol consumption and risk of uterine myoma: A systematic review and meta analysis. AB - BACKGROUND: The published data about alcohol consumption and uterine myoma are scanty and controversial: some studies found positive association whereas other studies showed no association. OBJECTIVES: To conduct a systematic review and meta-analysis to determine whether alcohol is a risk factor for myoma. SEARCH STRATEGY: A MEDLINE/EMBASE search was carried out, supplemented by manual searches of bibliographies of the selected studies. SELECTION CRITERIA: Articles published as full-length papers in English. In the review we included all identified studies. Otherwise, the inclusion criteria for studies included in the meta-analysis were: a) case-control or cohort studies, reporting original data; b) studies reporting original data on the association between alcohol consumption and myoma; c) diagnosis of myoma was ultrasound or histological confirmed and/or clinically based. DATA COLLECTION AND ANALYSIS: A total of 6 studies were identified for the review and 5 studies were included in the meta-analysis. The primary outcome was the incidence of uterine myoma in ever versus never alcohol drinkers and when data were available, we also analyzed categories of alcohol intake. We assessed the outcomes in the overall population and then we performed a subgroup analysis according to study design. Pooled estimates of the odds ratios (OR) with 95% confidence interval (CI) were calculated using random effects models. MAIN RESULTS: The summary OR (95%CI) of myoma forever versus never alcohol intake was 1.12 (0.94-1.34) with significant heterogeneity. The summary OR for current versus never drinking was 1.33 (1.01-1.76) with no heterogeneity. CONCLUSIONS: Ever alcohol consumption is not associated with myoma risk. Based on the data of two studies, current alcohol drinkers had a slightly borderline increased risk of diagnosis of myoma. In consideration of the very limited number of studies and the suggestion of a potential increased risk among current drinkers, further studies are required. PMID- 29176885 TI - Evaluation of myocardial glucose metabolism in hypertrophic cardiomyopathy using 18F-fluorodeoxyglucose positron emission tomography. AB - BACKGROUND: The purposes of this study were to assess the usefulness of myocardial 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) for evaluating myocardial metabolic status in hypertrophic cardiomyopathy (HCM) and the therapeutic efficacy of alcohol septal ablation (ASA) in hypertrophic obstructive cardiomyopathy (HOCM). METHODS: Thirty HCM patients (64.4+/-10.5 years, 14 male, 12 hypertrophic non-obstructive cardiomyopathy [HNCM], 16 HOCM, and 2 dilated phase of HCM) underwent 18F-FDG PET/CT. 18F-FDG uptake was semi-quantitatively evaluated using an uptake score in each 17 segment and the entire LV or regional standardized uptake value (SUV). RESULTS: 18F-FDG uptake was observed mostly in a hypertrophied myocardium in HNCM patients, whereas 18F-FDG was extensively accumulated beyond the hypertrophied myocardium in HOCM patients. There was a positive correlation between the summed uptake score of 18F-FDG and high-sensitive troponin T level in HNCM patients (r = 0.603, p = 0.049), whereas the score was positively correlated with brain natriuretic peptide level (r = 0.614, p = 0.011) in HOCM patients. In 10 patients who received ASA, the maximum SUV of the entire LV was significantly reduced from 5.6+/-2.6 to 3.2+/-2.1 (p = 0.040) after ASA. Reduction of that maximum SUV was particularly significant in the lateral region (from 5.5+/-2.6 to 2.9 +/-2.2, p = 0.024) but not significant in the anteroseptal region (from 4.5+/-2.6 to 2.9+/ 1.6, p = 0.12). CONCLUSION: Extensive 18F-FDG uptake beyond the hypertrophied myocardium was observed in HOCM. ASA attenuates 18F-FDG uptake in a remote lateral myocardium. PMID- 29176886 TI - Differences in phonetic discrimination stem from differences in psychoacoustic abilities in learning the sounds of a second language: Evidence from ERP research. AB - The scientific community has been divided as to the origin of individual differences in perceiving the sounds of a second language (L2). There are two alternative explanations: a general psychoacoustic origin vs. a speech-specific one. A previous study showed that such individual variability is linked to the perceivers' speech-specific capabilities, rather than the perceivers' psychoacoustic abilities. However, we assume that the selection of participants and parameters of sound stimuli might not appropriate. Therefore, we adjusted the sound stimuli and recorded event-related potentials (ERPs) from two groups of early, proficient Cantonese (L1)-Mandarin (L2) bilinguals who differed in their mastery of the Mandarin (L2) phonetic contrast /in-ing/, to explore whether the individual differences in perceiving L2 stem from participants' ability to discriminate various pure tones (frequency, duration and pattern). To precisely measure the participants' acoustic discrimination, mismatch negativity (MMN) elicited by the oddball paradigm was recorded in the experiment. The results showed that significant differences between good perceivers (GPs) and poor perceivers (PPs) were found in the three general acoustic conditions (frequency, duration and pattern), and the MMN amplitude for GP was significantly larger than for PP. Therefore, our results support a general psychoacoustic origin of individual variability in L2 phonetic mastery. PMID- 29176887 TI - First external quality assurance program for bloodstream Real-Time PCR monitoring of treatment response in clinical trials of Chagas disease. AB - Real-Time PCR (qPCR) testing is recommended as both a diagnostic and outcome measurement of etiological treatment in clinical practice and clinical trials of Chagas disease (CD), but no external quality assurance (EQA) program provides performance assessment of the assays in use. We implemented an EQA system to evaluate the performance of molecular biology laboratories involved in qPCR based follow-up in clinical trials of CD. An EQA program was devised for three clinical trials of CD: the E1224 (NCT01489228), a pro-drug of ravuconazole; the Sampling Study (NCT01678599), that used benznidazole, both conducted in Bolivia; and the CHAGASAZOL (NCT01162967), that tested posaconazole, conducted in Spain. Four proficiency testing panels containing negative controls and seronegative blood samples spiked with 1, 10 and 100 parasite equivalents (par. eq.)/mL of four Trypanosoma cruzi stocks, were sent from the Core Lab in Argentina to the participating laboratories located in Bolivia and Spain. Panels were analyzed simultaneously, blinded to sample allocation, at 4-month intervals. In addition, 302 random blood samples from both trials carried out in Bolivia were sent to Core Lab for retesting analysis. The analysis of proficiency testing panels gave 100% of accordance (within laboratory agreement) and concordance (between laboratory agreement) for all T. cruzi stocks at 100 par. eq./mL; whereas their values ranged from 71 to 100% and from 62 to 100% at 1 and 10 par. eq./mL, respectively, depending on the T. cruzi stock. The results obtained after twelve months of preparation confirmed the stability of blood samples in guanidine-EDTA buffer. No significant differences were found between qPCR results from Bolivian laboratory and Core Lab for retested clinical samples. This EQA program for qPCR analysis of CD patient samples may significantly contribute to ensuring the quality of laboratory data generated in clinical trials and molecular diagnostics laboratories of CD. PMID- 29176888 TI - Measuring the extent of overlaps in protected area designations. AB - Over the past decades, a number of national policies and international conventions have been implemented to promote the expansion of the world's protected area network, leading to a diversification of protected area strategies, types and designations. As a result, many areas are protected by more than one convention, legal instrument, or other effective means which may result in a lack of clarity around the governance and management regimes of particular locations. We assess the degree to which different designations overlap at global, regional and national levels to understand the extent of this phenomenon at different scales. We then compare the distribution and coverage of these multi designated areas in the terrestrial and marine realms at the global level and among different regions, and we present the percentage of each county's protected area extent that is under more than one designation. Our findings show that almost a quarter of the world's protected area network is protected through more than one designation. In fact, we have documented up to eight overlapping designations. These overlaps in protected area designations occur in every region of the world, both in the terrestrial and marine realms, but are more common in the terrestrial realm and in some regions, notably Europe. In the terrestrial realm, the most common overlap is between one national and one international designation. In the marine realm, the most common overlap is between any two national designations. Multi-designations are therefore a widespread phenomenon but its implications are not well understood. This analysis identifies, for the first time, multi-designated areas across all designation types. This is a key step to understand how these areas are managed and governed to then move towards integrated and collaborative approaches that consider the different management and conservation objectives of each designation. PMID- 29176889 TI - All-cause mortality among diabetic foot patients and related risk factors in Saudi Arabia. AB - BACKGROUND: Although Diabetes mellitus is a major public health problem in the Middle East and North Africa (MENA) region with high rates of diabetic foot complications, there are only limited data concerning mortality among such a high risk group. Therefore, the main aim of the current study was to assess all-cause mortality and its related predictors among diabetic patients with and without diabetic foot complications. METHODS: Using data from the Saudi National Diabetes Registry (SNDR), a total of 840 patients with type 1 or type 2 diabetes aged >=25 years with current or past history of diabetic foot ulcer (DFU) or diabetes related lower extremity amputation (LEA) were recruited in 2007 from active patients' files and followed up to 2013. These patients were compared with an equal number of age and gender matched diabetic patients without foot complication recruited at the same period. All patients were subjected to living status verification at 31st December 2013. RESULTS: The all-cause mortality rate among patients with DFU was 42.54 per 1000 person-years and among LEA patients was 86.80 per 1000 person-years among LEA patients for a total of 2280 and 1129 person-years of follow up respectively. The standardized mortality ratio (SMR) (95% CI) was 4.39 (3.55-5.23) and 7.21 (5.70-8.72) for cases with foot ulcer and LEA respectively. The percentage of deceased patients increased by almost twofold (18.5%) among patients with diabetic foot ulcer and more than threefold (32.2%) among patients with LEA compared with patients without diabetic foot complications (10.7%). The worst survival was among patients with LEA at 0.679 and the presence of diabetic nephropathy was the only significant independent risk factor for all-cause mortality among patients with diabetic foot complications. On the other hand, obese patients have demonstrated significantly reduced all-cause mortality rate. CONCLUSIONS: Diabetic patients with diabetic foot complications have an excess mortality rate when compared with diabetic counterparts without foot complications and the general population. Early interventions to prevent foot ulceration and consequent LEA as well as all the measurements for reducing the prevalence of microvascular and macrovascular complications should be considered. PMID- 29176890 TI - Persistent abnormalities in pulmonary arterial compliance after heart transplantation in patients with combined post-capillary and pre-capillary pulmonary hypertension. AB - BACKGROUND: The hemodynamic definitions of pulmonary hypertension (PH) in left heart disease have recently been refined to better match the characteristics required to reflect the presence of pulmonary vascular disease. Accordingly, we tested the hypothesis that abnormalities in the stiffness of pulmonary circulation would persist after heart transplantation in patients with combined post-capillary and pre-capillary PH (Cpc-PH) in contrast to those with isolated post-capillary PH (Ipc-PH). METHODS: We retrospectively analyzed right heart hemodynamics in a cohort of 295 consecutive patients with heart failure and advanced left ventricular systolic dysfunction (LVSD) before and 1 year after heart transplantation. RESULTS: According to their baseline hemodynamic profile, patients were classified as: 75 Cpc-PH, 111 Ipc-PH, and 98 without PH (no-PH), and 11 pre-capillary PH. One year after heart transplantation, pulmonary artery pressures, pulmonary vascular resistance and cardiac index normalized in all patients regardless of the baseline hemodynamic profile. However, pulmonary arterial compliance remained lower in Cpc-PH patients (from 1.6+/-1.2 at baseline to 3.7+/-1.4 ml/mmHg at 1 year) than in Ipc-PH (from 1.2+/-2.0 to 4.4+/-2.3 ml/mmHg) and no-PH patients (from 3.7+/-2.0 to 4.5+/-1.8 ml/mmHg); (adjusted p = 0.03 Ipc-PH vs. Cpc-PH INT<0.001). CONCLUSIONS: In heart failure patients with advanced LVSD, a hemodynamic profile characterized by Cpc-PH predicts the persistence of a stiffer pulmonary circulation at 1 year after heart transplantation. PMID- 29176891 TI - Quantitative proteomic analysis of amastigotes from Leishmania (L.) amazonensis LV79 and PH8 strains reveals molecular traits associated with the virulence phenotype. AB - BACKGROUND: Leishmaniasis is an antropozoonosis caused by Leishmania parasites that affects around 12 million people in 98 different countries. The disease has different clinical forms, which depend mainly on the parasite genetics and on the immunologic status of the host. The promastigote form of the parasite is transmitted by an infected female phlebotomine sand fly, is internalized by phagocytic cells, mainly macrophages, and converts into amastigotes which replicate inside these cells. Macrophages are important cells of the immune system, capable of efficiently killing intracellular pathogens. However, Leishmania can evade these mechanisms due to expression of virulence factors. Different strains of the same Leishmania species may have different infectivity and metastatic phenotypes in vivo, and we have previously shown that analysis of amastigote proteome can give important information on parasite infectivity. Differential abundance of virulence factors probably accounts for the higher virulence of PH8 strain parasites shown in this work. In order to test this hypothesis, we have quantitatively compared the proteomes of PH8 and LV79 lesion derived amastigotes using a label-free proteomic approach. METHODOLOGY/PRINCIPAL FINDINGS: In the present work, we have compared lesion development by L. (L.) amazonensis PH8 and LV79 strains in mice, showing that they have different virulence in vivo. Viability and numbers of lesion-derived amastigotes were accordingly significantly different. Proteome profiles can discriminate parasites from the two strains and several proteins were differentially expressed. CONCLUSIONS/SIGNIFICANCE: This work shows that PH8 strain is more virulent in mice, and that lesion-derived parasites from this strain are more viable and more infective in vitro. Amastigote proteome comparison identified GP63 as highly expressed in PH8 strain, and Superoxide Dismutase, Tryparedoxin Peroxidase and Heat Shock Protein 70 as more abundant in LV79 strain. The expression profile of all proteins and of the differential ones precisely classified PH8 and LV79 samples, indicating that the two strains have proteins with different abundances and that proteome profiles correlate with their phenotypes. PMID- 29176892 TI - Tobacco consumption and nicotine dependence in Bengo Province, Angola: A community-based survey. AB - There is concern about the potentially increasing use of tobacco in Angola. However, information on the frequency and determinants of this use is not systematised. This study aimed to estimate the prevalence of tobacco consumption and nicotine dependence among smokers in an Angolan population and considering individual socio-demographic and behavioural characteristics. A community-based survey with 2,472 respondents (age range: 15-64 years) was conducted in 2013-2014 in the country's Bengo Province. The collection methodology for assessing each type of tobacco consumption and its daily quantification followed the World Health Organization STEPwise approach to chronic disease risk factor surveillance. The Fagerstrom Test for Nicotine Dependence was also used to assess smokers. Mean values for prevalence of tobacco use and nicotine dependence were estimated by sex and by previously defined variables. Daily smoking (6.1%) was found to be higher for males (10.0%) them among females (2.6%), and the amount of ex-smokers (7.5%) was higher them smokers. Only 0.2% of those surveyed reported use of smokeless (chewing) tobacco. One-third of ever-smokers reported having started smoking daily before age 18. Nicotine dependence levels were classified as very low or low in 83.6% of the smokers. Daily smoking prevalence increased with age, and was higher in rural areas and among individuals with no formal education, lower incomes, and alcohol consumption. This population presented a low smoking prevalence, along with a low number of daily smoked cigarettes and low levels of nicotine dependency, despite the low prices of, and easy access to, manufactured cigarettes. These two factors conjugated with the current absence of an Angolan policy for tobacco control, enhance the susceptibility for rising overall tobacco use in the near future. PMID- 29176893 TI - The fear of being laughed at as additional diagnostic criterion in social anxiety disorder and avoidant personality disorder? AB - Social anxiety disorder (SAD) is the most common anxiety disorder and has considerable negative impact on social functioning, quality of life, and career progression of those affected. Gelotophobia (the fear of being laughed at) shares many similarities and has therefore been proposed as a subtype of SAD. This hypothesis has, however, never been tested in a clinical sample. Thus, the relationship between gelotophobia, SAD and avoidant personality disorder (APD) was investigated by examining a sample of 133 participants (64 psychiatric patients and 69 healthy controls matched for age and sex) using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (4th edition) and an established rating instrument for gelotophobia (GELOPH<15>). As expected, gelotophobia scores and the number of gelotophobic individuals were significantly higher among patients with SAD (n = 22) and APD (n = 12) compared to healthy controls and other psychiatric patients. Furthermore, gelotophobia scores were highest in patients suffering from both SAD and APD. In fact, all patients suffering from both disorders were also suffering from gelotophobia. As explained in the discussion, the observed data did not suggest that gelotophobia is a subtype of SAD. The findings rather imply that the fear of being laughed at is a symptom characteristic for both SAD and APD. Based on that, gelotophobia may prove to be a valuable additional diagnostic criterion for SAD and APD and the present results also contribute to the ongoing debate on the relationship between SAD and APD. PMID- 29176894 TI - Horizontal acquisition of a hypoxia-responsive molybdenum cofactor biosynthesis pathway contributed to Mycobacterium tuberculosis pathoadaptation. AB - The unique ability of the tuberculosis (TB) bacillus, Mycobacterium tuberculosis, to persist for long periods of time in lung hypoxic lesions chiefly contributes to the global burden of latent TB. We and others previously reported that the M. tuberculosis ancestor underwent massive episodes of horizontal gene transfer (HGT), mostly from environmental species. Here, we sought to explore whether such ancient HGT played a part in M. tuberculosis evolution towards pathogenicity. We were interested by a HGT-acquired M. tuberculosis-specific gene set, namely moaA1 D1, which is involved in the biosynthesis of the molybdenum cofactor. Horizontal acquisition of this gene set was striking because homologues of these moa genes are present all across the Mycobacterium genus, including in M. tuberculosis. Here, we discovered that, unlike their paralogues, the moaA1-D1 genes are strongly induced under hypoxia. In vitro, a M. tuberculosis moaA1-D1-null mutant has an impaired ability to respire nitrate, to enter dormancy and to survive in oxygen-limiting conditions. Conversely, heterologous expression of moaA1-D1 in the phylogenetically closest non-TB mycobacterium, Mycobacterium kansasii, which lacks these genes, improves its capacity to respire nitrate and grants it with a marked ability to survive oxygen depletion. In vivo, the M. tuberculosis moaA1-D1 null mutant shows impaired survival in hypoxic granulomas in C3HeB/FeJ mice, but not in normoxic lesions in C57BL/6 animals. Collectively, our results identify a novel pathway required for M. tuberculosis resistance to host-imposed stress, namely hypoxia, and provide evidence that ancient HGT bolstered M. tuberculosis evolution from an environmental species towards a pervasive human-adapted pathogen. PMID- 29176895 TI - Functional connectivity analysis of distracted drivers based on the wavelet phase coherence of functional near-infrared spectroscopy signals. AB - The present study aimed to evaluate the functional connectivity (FC) in relevant cortex areas during simulated driving with distraction based on functional near infrared spectroscopy (fNIRS) method. Twelve subjects were recruited to perform three types of driving tasks, namely, straight driving, straight driving with secondary auditory task, and straight driving with secondary visual vigilance task, on a driving simulator. The wavelet amplitude (WA) and wavelet phase coherence (WPCO) of the fNIRS signals were calculated in six frequency intervals: I, 0.6-2 Hz; II, 0.145-0.6 Hz; III, 0.052-0.145 Hz; IV, 0.021-0.052 Hz; and V, 0.0095-0.021 Hz, VI, 0.005-0.0095Hz. Results showed that secondary tasks during driving led to worse driving performance, brain activity changes, and dynamic configuration of the connectivity. The significantly lower WA value in the right motor cortex in interval IV, and higher WPCO values in intervals II, V, and VI were found with additional auditory task. Significant standard deviation of speed and lower WA values in the left prefrontal cortex and right prefrontal cortex in interval VI, and lower WPCO values in intervals I, IV, V, and VI were found under the additional visual vigilance task. The results suggest that the changed FC levels in intervals IV, V, and VI were more likely to reflect the driver's distraction condition. The present study provides new insights into the relationship between distracted driving behavior and brain activity. The method may be used for the evaluation of drivers' attention level. PMID- 29176896 TI - Aging-related limit of exercise efficacy on motor decline. AB - Identifying lifestyle strategies and allied neurobiological mechanisms that reduce aging-related motor impairment is imperative, given the accelerating number of retirees and increased life expectancy. A physically active lifestyle prior to old age can reduce risk of debilitating motor decline. However, if exercise is initiated after motor decline has begun in the lifespan, it is unknown if aging itself may impose a limit on exercise efficacy to decelerate further aging-related motor decline. In Brown-Norway/Fischer 344 F1 hybrid (BNF) rats, locomotor activity begins to decrease in middle age (12-18 months). One mechanism of aging-related motor decline may be decreased expression of GDNF family receptor, GFRalpha-1, which is decreased in substantia nigra (SN) between 12 and 30 months old. Moderate exercise, beginning at 18 months old, increases nigral GFRalpha-1 and tyrosine hydroxylase (TH) expression within 2 months. In aged rats, replenishing aging-related loss of GFRalpha-1 in SN increases TH in SN alone and locomotor activity. A moderate exercise regimen was initiated in sedentary male BNF rats in a longitudinal study to evaluate if exercise could attenuate aging-related motor decline when initiated at two different ages in the latter half of the lifespan (18 or 24 months old). Motor decline was reversed in the 18-, but not 24-month-old, cohort. However, exercise efficacy in the 18-month old group was reduced as the rats reached 27 months old. GFRalpha-1 expression was not increased in either cohort. These studies suggest exercise can decelerate motor decline when begun in the latter half of the lifespan, but its efficacy may be limited by age of initiation. Decreased plasticity of GFRalpha-1 expression following exercise may limit its efficacy to reverse motor decline. PMID- 29176897 TI - Long-term prognostic impact of left ventricular remodeling after a first myocardial infarction in modern clinical practice. AB - BACKGROUND: The association of left ventricular remodeling (LVR) after myocardial infarction (MI) with the subsequent risk of heart failure (HF) and death has not been studied in patients receiving optimal secondary prevention. METHODS AND RESULTS: We performed a long-term clinical follow-up of patients included in 2 prospective multicentric studies on LVR after first anterior MI. At 1-year echocardiography, LVR (>=20% increase in end-diastolic volume from baseline to 1 year) occurred in 67/215 (31%) patients in cohort 1 and in 87/226 (38%) patients in cohort 2. The prescription rate of secondary prevention medications was very high (beta-blockers at 1 year: 90% and 95% for cohorts 1 and 2, respectively; angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (ACE I/ARB) at 1 year: 93% and 97% for cohorts 1 and 2, respectively). Median clinical follow-up after LVR assessment was 11.0 years in cohort 1 and 7.8 years in cohort 2. In both cohorts, LVR patients had a progressive increase in the risk of cardiovascular death or hospitalization for HF (p = 0.0007 in cohort 1 and 0.009 in cohort 2) with unadjusted hazard ratios of 2.52 [1.45-4.36] and 2.52 [1.23 5.17], respectively. Similar results were obtained when cardiovascular death was considered as an isolated endpoint. After adjustement on baseline characteristics including ejection fraction, the association with the composite endpoint was unchanged. CONCLUSION: In a context of a modern therapeutic management with a large prescription of evidence-based medications, LVR remains independently associated with HF and cardiovascular death at long-term follow-up after MI. PMID- 29176898 TI - The influence of dietary and whole-body nutrient content on the excretion of a vertebrate consumer. AB - In many contexts, nutrient excretion by consumers can impact ecosystems by altering the availability of limiting nutrients. Variation in nutrient excretion can be predicted by mass balance models, most of which are premised on two key ideas: (1) consumers maintain fixed whole-body nutrient content (i.e., %N and %P), so-called fixed homeostasis; (2) if dietary nutrients are not matched to whole-body nutrients, excesses of any nutrient are released as excretion to maintain fixed homeostasis. Mass balance models thus predict that consumer excretion should be positively correlated with diet nutrients and negatively correlated with whole-body nutrients. Recent meta-analyses and field studies, however, have often failed to find these expected patterns, potentially because of a confounding influence-flexibility in whole-body nutrient content with diet quality (flexible homeostasis). Here, we explore the impact of flexible homeostasis on nutrient excretion by comparing the N and P excretion of four genetically diverged Trinidadian guppy (Poecilia reticulata) populations when reared on diets of variable P content. As predicted by mass balance, P excretion increased on the high-P diet, but, contrary to the notion of fixed homeostasis, guppy whole-body %P also increased on the high-P diet. While there was no overall correlation between excretion nutrients and whole-body nutrients, when the effect of diet on both whole-body and excretion nutrients was included, we detected the expected negative correlation between whole-body N:P and excretion N:P. This last result suggests that mass balance can predict excretion rates within species, but only if dietary effects on whole-body nutrient content are controlled. Flexible homeostasis can obscure patterns predicted by mass balance, creating an imperative to accurately capture an organism's diet quality in predicting its excretion rate. PMID- 29176899 TI - Supine posture changes lung volumes and increases ventilation heterogeneity in cystic fibrosis. AB - INTRODUCTION: Lung Clearance Index (LCI) is recognised as an early marker of cystic fibrosis (CF) lung disease. The effect of posture on LCI however is important when considering longitudinal measurements from infancy and when comparing LCI to imaging studies. METHODS: 35 children with CF and 28 healthy controls (HC) were assessed. Multiple breath washout (MBW) was performed both sitting and supine in triplicate and analysed for LCI, Scond, Sacin, and lung volumes. These values were also corrected for the Fowler dead-space to create 'alveolar' indices. RESULTS: From sitting to supine there was a significant increase in LCI and a significant decrease in FRC for both CF and HC (p<0.01). LCI, when adjusted to estimate 'alveolar' LCI (LCIalv), increased the magnitude of change with posture for both LCIalv and FRCalv in both groups, with a greater effect of change in lung volume in HC compared with children with CF. The % change in LCIalv for all subjects correlated significantly with lung volume % changes, most notably tidal volume/functional residual capacity (Vtalv/FRCalv (r = 0.54,p<0.001)). CONCLUSION: There is a significant increase in LCI from sitting to supine, which we believe to be in part due to changes in lung volume and also increasing ventilation heterogeneity related to posture. This may have implications in longitudinal measurements from infancy to older childhood and for studies comparing supine imaging methods to LCI. PMID- 29176900 TI - Consensual punishment does not promote cooperation in the six-person prisoner's dilemma game with noisy public monitoring. AB - We study the effects of different punishment institutions on cooperation in a six person prisoner's dilemma game in which actors observe others' cooperation with some noise (i.e. imperfect public monitoring). Previous research has shown that peer punishment can sustain cooperation, if a certain proportion of group members punish defectors at a cost to themselves. However, in the presence of noise, co operators will sometimes be mistaken for defectors and punished, and defectors will sometimes be mistaken for co-operators and escape punishment. Both types of mistakes are detrimental for cooperation because cooperation is discouraged and defection is encouraged. By means of a laboratory experiment, we study whether this adverse effect of noise can be mitigated by consensual punishment. The more other group members have to agree on punishing a defector, the less likely will a co-operator be punished by mistake. We compare a punishment institution in which each subject decides individually whether to punish another, with institutions in which punishments are only implemented if subjects reach sufficient consensus that a particular group member should be punished. In conditions without noise, we find that cooperation and subjects' payoffs are higher if more consensus is required before a punishment is implemented. In conditions with noise, cooperation is lower if more consensus is required. Moreover, with noise, subjects' payoffs are lower under all punishment institutions than in the control condition without punishment opportunities. Our results narrow down the conditions under which punishment institutions can promote cooperation if such cooperation is noisy. PMID- 29176902 TI - Detection of Leishmania spp in silvatic mammals and isolation of Leishmania (Viannia) braziliensis from Rattus rattus in an endemic area for leishmaniasis in Minas Gerais State, Brazil. AB - Knowledge of potential reservoirs of Leishmania spp. in an anthropic environment is important so that surveillance and control measures can be implemented. The aim of this study was to investigate the infection by Leishmania in small mammals in an area located in Minas Gerais, Brazil, that undergoes changes in its natural environment and presents autochthonous human cases of cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL). For the capture of the animals, Sherman and Tomahawk traps were used and distributed in the peridomicile of houses with reports of autochthonous cases of CL or VL. Six catches were carried out on two consecutive nights with intervals of two months during one year and samples of spleen, liver, tail skin, ear skin and bone marrow of the animals were obtained. Parasitological and molecular methods were used to detect the infection. Identification of the Leishmania species was performed by PCR RFLPhsp70. Twenty five animals of four species were captured: ten Rattus rattus, nine Didelphis albiventris, five Cerradomys subflavus and one Marmosops incanus. In the PCR hsp70, five animals were positive (20%). The Leishmania species identified in PCR RFLPhsp70 were: Leishmania braziliensis in D. albiventris (2), C. subflavus (1) and R. rattus (1) and Leishmania infantum in R. rattus (1). The highest positivity rate for L. braziliensis was obtained in the liver samples. The spleen was the only tissue positive for L. infantum. It was isolated in culture medium L. braziliensis from two samples (liver and spleen) of R. rattus. This is the first record of isolation of L. braziliensis from R. rattus in the southeastern region of Brazil. These results are relevant to the knowledge of the epidemiology of leishmaniasis in the region, mainly in the investigation of the presence of hosts and possible reservoirs of the parasite. PMID- 29176901 TI - Graded expression of source memory revealed by analysis of gaze direction. AB - During source memory studies, knowledge of some detail about the context of a previously experienced item or event is tested. Here, participants attended to different objects presented at different quadrants on a screen. In a later test phase, a single object was presented in all four quadrants, and participants verbally reported whether the object was new or previously seen (item recognition), and if it was previously seen, they indicated the original screen location (source memory). We combined this test with eye-tracking to determine whether attention to an object during encoding would correlate with later recognition of the object and memory of its source location, and whether eye movements at test can reveal attention to the correct source location in the absence of correct explicit verbal responses. The amount of time spent looking at an object during encoding was not related to later object recognition or source recollection. However, we found that eye movements at test reveal retention of source information about an object in the absence of accurate retrieval of source information as assessed by verbal response. When participants correctly recognized an object but incorrectly indicated the source information, significantly more time was spent looking at the correct source location than to incorrect, non-selected locations. Moreover, when participants correctly recognized an object but said they could not remember the source information, significantly more time was spent looking at the correct source location. These results are consistent with the hypothesis that eye movements are sensitive to attention or other graded mental processes which can underlie the retrieval of source memories that can then be expressed verbally in a thresholded manner. PMID- 29176903 TI - Axonal and myelinic pathology in 5xFAD Alzheimer's mouse spinal cord. AB - As an extension of the brain, the spinal cord has unique properties which could allow us to gain a better understanding of CNS pathology. The brain and cord share the same cellular components, yet the latter is simpler in cytoarchitecture and connectivity. In Alzheimer's research, virtually all focus is on brain pathology, however it has been shown that transgenic Alzheimer's mouse models accumulate beta amyloid plaques in spinal cord, suggesting that the cord possesses the same molecular machinery and conditions for plaque formation. Here we report a spatial-temporal map of plaque load in 5xFAD mouse spinal cord. We found that plaques started to appear at 11 weeks, then exhibited a time dependent increase and differential distribution along the cord. More plaques were found in cervical than other spinal levels at all time points examined. Despite heavy plaque load at 6 months, the number of cervical motor neurons in 5xFAD mice is comparable to wild type littermates. On detailed microscopic examination, fine beta amyloid-containing and beta sheet-rich thread-like structures were found in the peri-axonal space of many axons. Importantly, these novel structures appear before any plaque deposits are visible in young mice spinal cord and they co localize with axonal swellings at later stages, suggesting that these thread-like structures might represent the initial stages of plaque formation, and could play a role in axonal damage. Additionally, we were able to demonstrate increasing myelinopathy in aged 5xFAD mouse spinal cord using the lipid probe Nile Red with high resolution. Collectively, we found significant amyloid pathology in grey and white matter of the 5xFAD mouse spinal cord which indicates that this structure maybe a useful platform to study mechanisms of Alzheimer's pathology and disease progression. PMID- 29176904 TI - Mobile microscopy as a screening tool for oral cancer in India: A pilot study. AB - Oral cancer is the most common type of cancer among men in India and other countries in South Asia. Late diagnosis contributes significantly to this mortality, highlighting the need for effective and specific point-of-care diagnostic tools. The same regions with high prevalence of oral cancer have seen extensive growth in mobile phone infrastructure, which enables widespread access to telemedicine services. In this work, we describe the evaluation of an automated tablet-based mobile microscope as an adjunct for telemedicine-based oral cancer screening in India. Brush biopsy, a minimally invasive sampling technique was combined with a simplified staining protocol and a tablet-based mobile microscope to facilitate local collection of digital images and remote evaluation of the images by clinicians. The tablet-based mobile microscope (CellScope device) combines an iPad Mini with collection optics, LED illumination and Bluetooth-controlled motors to scan a slide specimen and capture high resolution images of stained brush biopsy samples. Researchers at the Mazumdar Shaw Medical Foundation (MSMF) in Bangalore, India used the instrument to collect and send randomly selected images of each slide for telepathology review. Evaluation of the concordance between gold standard histology, conventional microscopy cytology, and remote pathologist review of the images was performed as part of a pilot study of mobile microscopy as a screening tool for oral cancer. Results indicated that the instrument successfully collected images of sufficient quality to enable remote diagnoses that show concordance with existing techniques. Further studies will evaluate the effectiveness of oral cancer screening with mobile microscopy by minimally trained technicians in low-resource settings. PMID- 29176906 TI - Nonmarital First Births, Marriage, and Income Inequality. AB - Many aggregate-level studies suggest a relationship between economic inequality and socio-demographic outcomes such as family formation, health, and mortality; but individual-level evidence is lacking. Nor is there satisfactory evidence on the mechanisms by which inequality may have an effect. We study the determinants of transitions to a nonmarital first birth as a single parent or as a cohabiting parent compared to transitions to marriage prior to a first birth among unmarried, childless young adults in the National Longitudinal Survey of Youth, 1997 cohort, from 1997 to 2011. We include measures of county-group-level household income inequality and of the availability of jobs typically held by high-school graduates and which pay above-poverty wages. We find that greater income inequality is associated with a reduced likelihood of transitioning to marriage prior to a first birth for both women and men. The association between levels of inequality and transitions to marriage can be partially accounted for by the availability of jobs of the type we measured. Some models also suggest that greater income inequality is associated with a reduced likelihood of transitioning to a first birth while cohabiting. PMID- 29176905 TI - Oral versus intravenous methylprednisolone for the treatment of multiple sclerosis relapses: A meta-analysis of randomized controlled trials. AB - BACKGROUND: Intravenous glucocorticoids are recommended for multiple sclerosis (MS). However, they can be inconvenient and expensive. Due to their convenience and low cost, oral glucocorticoids may be an alternative treatment. Recently, several studies have shown that there is no difference in efficacy and safety between oral methylprednisolone (oMP) and intravenous methylprednisolone (ivMP). OBJECTIVES: We sought to assess the clinical efficacy, safety and tolerability of oral methylprednisolone versus intravenous methylprednisolone for MS relapses in this meta-analysis. METHODS: Randomized controlled trials (RCTs) evaluating the clinical efficacy, safety and tolerability of oral methylprednisolone versus intravenous methylprednisolone for MS relapses were searched in PubMed, Cochrane Library, Medline, EMBASE and China Biology Medicine until October 25, 2016, without language restrictions. The proportion of patients who had improved by day 28 was chosen as the efficacy outcome. We chose the risk ratio (RR) to analyze each trial with the 95% confidence interval (95% CI). We also used the fixed effects model (Mantel-Haenszel approach) to calculate the pooled relative effect estimates. RESULTS: A total of 5 trials were identified, which included 369 patients. The results of our meta-analysis revealed that no significant difference existed in relapse improvement at day 28 between oMP and ivMP (RR 0.96, 95% CI 0.84 to 1.10). No evidence of heterogeneity existed among the trials (P = 0.45, I2 = 0%). Both treatments were equally safe and well tolerated except that insomnia was more likely to occur in the oMP group compared to the ivMP group. CONCLUSION: Our meta-analysis reveals strong evidence that oMP is not inferior to ivMP in increasing the proportion of patients experiencing clinical improvement at day 28. In addition, both routes of administration are equally well tolerated and safe. These findings suggest that we may be able to replace ivMP with oMP to treat MS relapses.

PMID- 29176908 TI - Modified Facile Synthesis for Quantitatively Fluorescent Carbon Dots. AB - A simple yet consequential modification was made to the popular carbonization processing of citric acid - polyethylenimine precursor mixtures to produce carbon dots (CDots). The modification was primarily on pushing the carbonization processing a little harder at a higher temperature, such as the hydrothermal processing condition of around 330 degrees C for 6 hours. The CDots thus produced are comparable in spectroscopic and other properties to those obtained in other more controlled syntheses including the deliberate chemical functionalization of preprocessed and selected small carbon nanoparticles, demonstrating the consistency in CDots and reaffirming their general definition as carbon nanoparticles with surface passivation by organic or other species. Equally significant is the finding that the modified processing of citric acid - polyethylenimine precursor mixtures could yield CDots of record-setting fluorescence performance, approaching the upper limit of being quantitatively fluorescent. Thus, the reported work serves as a demonstration on not only the need in selecting the right processing conditions and its associated opportunities in one-pot syntheses of CDots, but also the feasibility in pursuing the preparation of quantitatively fluorescent CDots, which represents an important milestone in the development and understanding of these fluorescent carbon nanomaterials. PMID- 29176909 TI - Computer-aided Molecular Design of Water Compatible Visible Light Photosensitizers for Dental Adhesive. AB - Dental adhesive resin undergoes phase separation during its infiltration through the wet demineralized dentin and it has been observed previously that the hydrophilic-rich phase is a vulnerable region for failure due to the lack of photo-polymerization and crosslinking density. The lack of photo-polymerization is mostly due to the partitioning of photo-initiators in low concentrations within this phase. Here, a computational approach has been employed to design candidate water compatible visible light photosensitizers which could improve the photo-polymerization of the hydrophilic-rich phase. This study is an extension of our previous work. QSPRs were developed for properties related to the photo polymerization reaction of the adhesive monomers and hydrophilicity of the photosensitizer using connectivity indices as descriptors. QSPRs and structural constraints were formulated into an optimization problem which was solved stochastically via Tabu Search. Four candidate photosensitizer molecules have been proposed here which have the iminium ion as a common feature. PMID- 29176910 TI - The effect of Ca2+ ions and ionic strength on Mn(II) oxidation by spores of the marine Bacillus sp. SG-1. AB - Manganese(IV) oxides, believed to form primarily through microbial activities, are extremely important mineral phases in marine environments where they scavenge a variety of trace elements and thereby control their distributions. The presence of various ions common in seawater are known to influence Mn oxide mineralogy yet little is known about the effect of these ions on the kinetics of bacterial Mn(II) oxidation and Mn oxide formation. We examined factors affecting bacterial Mn(II) oxidation by spores of the marine Bacillus sp. strain SG-1 in natural and artificial seawater of varying ionic conditions. Ca2+ concentration dramatically affected Mn(II) oxidation, while Mg2+, Sr2+, K+, Na+ and NO3- ions had no effect. The rate of Mn(II) oxidation at 10mM Ca2+ (seawater composition) was four or five times that without Ca2+. The relationship between Ca2+ content and oxidation rate demonstrates that the equilibrium constant is small (on the order of 0.1) and the binding coefficient is 0.5. The pH optimum for Mn(II) oxidation changed depending on the amount of Ca2+ present, suggesting that Ca2+ exerts a direct effect on the enzyme perhaps as a stabilizing bridge between polypeptide components. We also examined the effect of varying concentrations of NaCl or KNO3 (0 mM - 2000 mM) on the kinetics of Mn(II) oxidation in solutions containing 10 mM Ca2+. Mn(II) oxidation was unaffected by changes in ionic strength (I) below 0.2, but it was inhibited by increasing salt concentrations above this value. Our results suggest that the critical coagulation concentration is around 200 mM of salt (I = ca. 0.2), and that the ionic strength of seawater (I > 0.2) accelerates the precipitation of Mn oxides around the spores. Under these conditions, the aggregation of Mn oxides reduces the supply of dissolved O2 and/or Mn2+ and inhibits the Mn(II) -> Mn(III) step controlling the enzymatic oxidation of Mn(II). Our results suggest that the hardness and ionic strength of the aquatic environment at circumneutral pH strongly influences the rate of biologically mediated Mn(II) oxidation. PMID- 29176911 TI - Episodes of fluvial and volcanic activity in Mangala Valles, Mars. AB - A new mapping-based study of the 900-km-long Mangala Valles outflow system was motivated by the availability of new high-resolution images and continued debates about the roles of water and lava in outflow channels on Mars. This study uses photogeologic analysis, geomorphic surface mapping, cratering statistics, and relative stratigraphy. Results show that Mangala Valles underwent at least two episodes of fluvial activity and at least three episodes of volcanic activity during the Late Amazonian. The occurrence of scoured bedrock at the base of the mapped stratigraphy, in addition to evidence provided by crater retention ages, suggests that fluvial activity preceded the deposition of two of the volcanic units. Crater counts performed at 30 locations throughout the area have allowed us to construct the following timeline: (1) formation of Noachian Highlands and possible initial flooding event(s) before ~1 Ga, (2) emplacement of Tharsis lava flows in the valley from ~700 to 1000 Ma, (3) a megaflooding event at ~700-800 Ma sourced from Mangala Fossa, (4) valley fill by a sequence of lava flows sourced from Mangala Fossa ~400-500 Ma, (5) another megaflooding event from ~400 Ma, (6) a final phase of volcanism sourced from Mangala Fossa ~300-350 Ma, and (7) emplacement of eolian sedimentary deposits in the northern portion of the valley ~300 Ma. These results are consistent with alternating episodes of aqueous flooding and volcanism in the valles. This pattern of geologic activity is similar to that of other outflow systems, such as Kasei Valles, suggesting that there is a recurring, and perhaps coupled, nature of these processes on Mars. PMID- 29176912 TI - Older Adults' Perceptions of Nutrition as Protective Against Detrimental Effects of Environmental Pollution. AB - The aging process makes older adults vulnerable to the detrimental health effects of environmental contaminants. Our study assessed older adults' perceptions regarding diet being protective against environmental contaminants, their levels of concern about exposure, and their interest in learning about protective food related strategies. A needs assessment to collect such information has not been conducted among older adults. Health fair survey results showed that they perceived diet as beneficial against contaminants, were concerned about health implications of exposure, and were interested in learning how to protect health through diet-related strategies. Results suggest that a nutrition-focused curriculum addressing how dietary strategies can help protect against environmental contaminants is needed for Extension professionals.

PMID- 29176915 TI - The Association of Ethnic Pride With Health and Social Outcomes Among Young Black and Latino Men After Release From Jail. AB - The goal of this study was to understand whether ethnic pride among young, incarcerated Black and Latino men was associated with successful community reentry. We interviewed 397 Black and Latino men 16 to 18 years old in a New York City jail and then again 1 year after their release to determine the relationship between participants' sense of ethnic pride during incarceration, and substance use, violence, recidivism, and education/ employment after release from jail. Participants with higher ethnic pride scores were less likely to engage in illegal activities and be reincarcerated. Ethnic pride was also associated with feeling safe in gangs and positive attitudes toward avoiding violence in situations of conflict. Ethnic pride was not associated with substance use, education, or engagement in community-based organizations post release. This study demonstrated that ethnic pride might be a source of strength that young men of color can harness for successful community reentry after release from jail. PMID- 29176913 TI - Addiction Treatment Clients' Reactions to Graphic Warning Labels on Cigarette Packs. AB - Graphic warning labels (GWLs) on cigarette packs have been tested among diverse groups at high risk for tobacco use. However, little is known about the effectiveness of GWL interventions for persons with substance use disorders, whose smoking prevalence is 3 to 4 times that of the general population. After an experimental study which exposed clients in residential addiction treatment to GWLs for 30 days, we conducted five focus groups with trial participants (N = 33) to explore how exposure to the labels may have impacted their readiness to quit smoking. Focus group interviews were analyzed thematically. Interviewees reported that GWLs were more effective than text-based warnings for increasing quit intentions due to greater cognitive and emotional impact. Male and female interviewees expressed gender-specific reactions to the labels. Addiction treatment programs are a strategic site for GWL and other tobacco interventions due to the tobacco-vulnerable populations they serve. PMID- 29176916 TI - Simulation and Measurement of Through-the-Earth, Extremely Low-Frequency Signals Using Copper-Clad Steel Ground Rods. AB - The underground mining environment can greatly affect radio signal propagation. Understanding how the earth affects signal propagation is a key to evaluating communications systems used during a mine emergency. One type of communication system is through-the-earth, which can utilize extremely low frequencies (ELF). This paper presents the simulation and measurement results of recent National Institute for Occupational Safety and Health (NIOSH) research aimed at investigating current injection at ELF, and in particular, ground contact impedance. Measurements were taken at an outside surface testing location. The results obtained from modeling and measurement are characterized by electrode impedance, and the voltage received between two distant electrodes. This paper concludes with a discussion of design considerations found to affect low frequency communication systems utilizing ground rods to inject a current into the earth. PMID- 29176917 TI - Fluvial geomorphology on Earth-like planetary surfaces: A review. AB - Morphological evidence for ancient channelized flows (fluvial and fluvial-like landforms) exists on the surfaces of all of the inner planets and on some of the satellites of the Solar System. In some cases, the relevant fluid flows are related to a planetary evolution that involves the global cycling of a volatile component (water for Earth and Mars; methane for Saturn's moon Titan). In other cases, as on Mercury, Venus, Earth's moon, and Jupiter's moon Io, the flows were of highly fluid lava. The discovery, in 1972, of what are now known to be fluvial channels and valleys on Mars sparked a major controversy over the role of water in shaping the surface of that planet. The recognition of the fluvial character of these features has opened unresolved fundamental questions about the geological history of water on Mars, including the presence of an ancient ocean and the operation of a hydrological cycle during the earliest phases of planetary history. Other fundamental questions posed by fluvial and fluvial-like features on planetary bodies include the possible erosive action of large-scale outpourings of very fluid lavas, such as those that may have produced the remarkable canali forms on Venus; the ability of exotic fluids, such as methane, to create fluvial-like landforms, as observed on Saturn's moon, Titan; and the nature of sedimentation and erosion under different conditions of planetary surface gravity. Planetary fluvial geomorphology also illustrates fundamental epistemological and methodological issues, including the role of analogy in geomorphological/geological inquiry. PMID- 29176918 TI - The influence of transcranial alternating current stimulation (tACS) on fluid intelligence: An fMRI study. AB - The past decades have witnessed a huge interest in uncovering the neural bases of intelligence (e.g., Stelmack, & Houlihan, 1995; Stelmack, Knott, & Beauchamp, 2003). This study investigated the influence of transcranial alternating current stimulation (tACS) on fluid intelligence performance and corresponding brain activation. Previous findings showed that left parietal theta tACS leads to a transient increase in fluid reasoning performance. In an attempt to extend and replicate these findings, we combined theta tACS with fMRI. In a double-blind sham-controlled experiment, N = 20 participants worked on two intelligence tasks (matrices and paper folding) after theta tACS was applied to the left parietal cortex. Stimulation-induced brain activation changes were recorded during task processing using fMRI. Results showed that theta tACS significantly increased fluid intelligence performance when working on difficult items in the matrices test; no effect was observed for the visuo-spatial paper folding test. Whole brain analyses showed that left parietal brain stimulation was accompanied by lower activation in task-irrelevant brain areas. Complemental ROI analyses revealed a tendency towards lower activation in the left inferior parietal cortex. These findings corroborate the functional role of left parietal theta activity in fluid reasoning and are in line with the neural efficiency hypothesis. PMID- 29176920 TI - The role of extra-foveal processing in 3D imaging. AB - The field of medical image quality has relied on the assumption that metrics of image quality for simple visual detection tasks are a reliable proxy for the more clinically realistic visual search tasks. Rank order of signal detectability across conditions often generalizes from detection to search tasks. Here, we argue that search in 3D images represents a paradigm shift in medical imaging: radiologists typically cannot exhaustively scrutinize all regions of interest with the high acuity fovea requiring detection of signals with extra-foveal areas (visual periphery) of the human retina. We hypothesize that extra-foveal processing can alter the detectability of certain types of signals in medical images with important implications for search in 3D medical images. We compare visual search of two different types of signals in 2D vs. 3D images. We show that a small microcalcification-like signal is more highly detectable than a larger mass-like signal in 2D search, but its detectability largely decreases (relative to the larger signal) in the 3D search task. Utilizing measurements of observer detectability as a function retinal eccentricity and observer eye fixations we can predict the pattern of results in the 2D and 3D search studies. Our findings: 1) suggest that observer performance findings with 2D search might not always generalize to 3D search; 2) motivate the development of a new family of model observers that take into account the inhomogeneous visual processing across the retina (foveated model observers). PMID- 29176919 TI - Clinically differentiating life-course-persistent and adolescence-limited conduct problems: Is age-of-onset really enough? AB - One important subtyping of behavior problems is Moffitt's (1993) "life-course persistent" (LCP) and "adolescent limited" (AL) categories of antisocial behavior, which she differentiated in terms of high impulsivity, poor academic performance, and aggression. These problems may be exacerbated by the cumulative effects of chronic stress. Copious evidence has documented validity and developmental differences between these subtypes, whereas far fewer data exist regarding their clinical utility, in spite of the Diagnostic and Statistical Manual's nomenclature including corresponding subtypes based on age-of-onset of behavioral symptoms. The present study evaluated how well age-of-onset based subtyping identifies distinct developmental patterns of antisocial behavior corresponding to Moffitt's subtypes in terms of risk factors and gender between LCP and AL in a prospective sample of chronically stressed youth. A computerized assessment tool (ALEXSA(c)) was used to obtain data from 1,147 youth aged 8-16. Implications for clinical assessment and intervention strategy, particularly with stressed youth, are discussed. PMID- 29176921 TI - Foveated Model Observers to predict human performance in 3D images. AB - We evaluate 3D search requires model observers that take into account the peripheral human visual processing (foveated models) to predict human observer performance. We show that two different 3D tasks, free search and location-known detection, influence the relative human visual detectability of two signals of different sizes in synthetic backgrounds mimicking the noise found in 3D digital breast tomosynthesis. One of the signals resembled a microcalcification (a small and bright sphere), while the other one was designed to look like a mass (a larger Gaussian blob). We evaluated current standard models observers (Hotelling; Channelized Hotelling; non-prewhitening matched filter with eye filter, NPWE; and non-prewhitening matched filter model, NPW) and showed that they incorrectly predict the relative detectability of the two signals in 3D search. We propose a new model observer (3D Foveated Channelized Hotelling Observer) that incorporates the properties of the visual system over a large visual field (fovea and periphery). We show that the foveated model observer can accurately predict the rank order of detectability of the signals in 3D images for each task. Together, these results motivate the use of a new generation of foveated model observers for predicting image quality for search tasks in 3D imaging modalities such as digital breast tomosynthesis or computed tomography. PMID- 29176923 TI - Effects Of Symmetry On The Structural Controllability Of Neural Networks: A Perspective. AB - The controllability of a dynamical system or network describes whether a given set of control inputs can completely exert influence in order to drive the system towards a desired state. Structural controllability develops the canonical coupling structures in a network that lead to un-controllability, but does not account for the effects of explicit symmetries contained in a network. Recent work has made use of this framework to determine the minimum number and location of the optimal actuators necessary to completely control complex networks. In systems or networks with structural symmetries, group representation theory provides the mechanisms for how the symmetry contained in a network will influence its controllability, and thus affects the placement of these critical actuators, which is a topic of broad interest in science from ecological, biological and man-made networks to engineering systems and design. PMID- 29176922 TI - Peptide-coated semiconductor nanocrystals for biomedical applications. AB - We have developed a new functionalization approach for semiconductor nanocrystals based on a single-step exchange of surface ligands with custom-designed peptides. This peptide-coating technique yield small, monodisperse and very stable water soluble NCs that remain bright and photostable. We have used this approach on several types of core and core-shell NCs in the visible and near-infrared spectrum range and used fluorescence correlation spectroscopy for rapid assessment of the colloidal and photophysical properties of the resulting particles. This peptide coating strategy has several advantages: it yields probes that are immediately biocompatible; it is amenable to improvements of the different properties (solubilization, functionalization, etc) via rational design, parallel synthesis, or molecular evolution; it permits the combination of several functions on individual NCs. These functionalized NCs have been used for diverse biomedical applications. Two are discussed here: single-particle tracking of membrane receptor in live cells and combined fluorescence and PET imaging of targeted delivery in live animals. PMID- 29176924 TI - Novel phonotactic learning: Tracking syllable-position and co-occurrence constraints. AB - Are syllable-level and co-occurrence representations simultaneously available when one learns novel phonotactics? After training on word-medial consonant restrictions (e.g., word-medial onsets P/Z, codas D/F, and cross-syllable consonant clusters FP/DZ in items like baF.Pev, tiD.Zek), adults falsely recognized novel items containing restricted consonants with the same co occurrences (e.g., FP) more often than those with different co-occurrences (e.g., FZ) when syllable-position information was kept constant (e.g., vuF.Pet vs. vuF.Zet; Experiment 1). Thus, adults tracked co-occurrence information. Additionally, even when co-occurrence information was different from training, participants more often falsely recognized novel items that contained restricted consonants in the same (e.g., onset-Z) rather than different syllable positions (e.g., coda-Z), whether the restricted consonants were in the same (word-medial, e.g., vuF.Zet vs. vuZ.Fet, Experiment 2) or different word positions (word-edge, e.g., Zut.veF vs. Fut.veZ, Experiment 3). Thus, adults also tracked syllable level information. These findings show that adults spontaneously represent sound sequences at multiple levels. PMID- 29176925 TI - Two HTS options for a 600 MHz insert of a 1.3 GHz LTS/HTS NMR magnet: YBCO and BSCCO. AB - In 2008, the Phase 3 program to complete a 1.3 GHz (30.5 T) NMR magnet started at the Francis Bitter Magnet Laboratory, Massachusetts Institute of Technology. It comprises two sub-phases, 3A and 3B. In Phase 3A, a 600 MHz high temperature superconductor (HTS) insert magnet (H600) will be designed, constructed, and operated in the bore of a 500 MHz low temperature superconductor (LTS) background magnet. This will be followed by Phase 3B, in which the H600 will be combined with a 700 MHz LTS background magnet to complete a 1.3 GHz NMR LTS/HTS magnet. This paper presents and discusses design issues for two conductor options for H600: BiSCCO-2223 (Bi2223) and coated-YBCO or its variants, here designated as YBCO. For each conductor option, we focused on the following issues: 1) elastic and thermal properties; 2) critical current vs. field performance; 3) splice and index heat dissipations; 4) mechanical and thermal stresses; and 5) protection. PMID- 29176926 TI - Changes in the genetic structure of an invasive earthworm species (Lumbricus terrestris, Lumbricidae) along an urban - rural gradient in North America. AB - European earthworms were introduced to North America by European settlers about 400 years ago. Human-mediated introductions significantly contributed to the spread of European species, which commonly are used as fishing bait and are often disposed deliberately in the wild. We investigated the genetic structure of Lumbricus terrestris in a 100 km range south of Calgary, Canada, an area that likely was devoid of this species two decades ago. Genetic relationships among populations, gene flow, and migration events among populations were investigated using seven microsatellite markers and the mitochondrial 16S rDNA gene. Earthworms were collected at different distances from the city and included fishing baits from three different bait distributors. The results suggest that field populations in Alberta established rather recently and that bait and field individuals in the study area have a common origin. Genetic variance within populations decreased outside of the urban area, and the most distant populations likely originated from a single introduction event. The results emphasise the utility of molecular tools to understand the spatial extent and connectivity of populations of exotic species, in particular soil-delling species, that invade native ecosystems and to obtain information on the origin of populations. Such information is crucial for developing management and prevention strategies to limit and control establishment of non-native earthworms in North America. PMID- 29176928 TI - The Management of Disclosure in Children's Accounts of Domestic Violence: Practices of Telling and Not Telling. AB - Children and young people who experience domestic violence are often represented as passive witnesses, too vulnerable to tell the stories of their own lives. This article reports on findings from a 2 year European research project (Understanding Agency and Resistance Strategies, UNARS) with children and young people in Greece, Italy, Spain and the UK, who had experienced domestic violence. It explores children and young people's understandings of their own capacity to reflect on and disclose their experiences Extracts from individual interviews with 107 children and young people (age 8-18) were analysed. Three themes are presented, that illustrate children and young people's strategies for managing disclosure: (1) "Being silenced or choosing silence?", explores children and young people's practices of self-silencing; (2) "Managing disclosures: Finding ways to tell" outlines how children and young people value self-expression, and the strategies they use to disclose safely; and in (3) "Speaking with many voices" considers how children and young people's accounts of their experiences are constituted relationally, and are often polyvocal. The article concludes that children and young people can be articulate, strategic and reflexive communicators, and that good support for families struggling with domestic violence must enable space for children and young people's voice to be heard. This is possible only in an integrated framework able to encompass multiple layers and perspectives, rather than privileging the adult point of view. Practitioners who work with families affected by domestic violence need to recognize that children and young people are able to reflect on and speak about their experiences. This requires that attention is paid to the complexity of children and young people's communication practices, and the relational context of those communications. PMID- 29176930 TI - Growth kinetics of omega particles in beta-Ti matrix studied by in-situ small angle x-ray scattering. AB - Nucleation and growth kinetics of nanoparticles of hexagonal omega phase in a body-centered cubic beta titanium matrix in single crystals of beta-Ti alloys were investigated by small-angle x-ray scattering measured in-situ during ageing at various temperatures up to 450 degrees C. The experimental data were compared with numerical simulations based on a three-dimensional short-range order model of nanoparticle self-ordering. The x-ray contrast of the particles is caused by an inhomogeneous distribution of impurity atoms (Mo, Fe and Al), whose density profile around growing nanoparticles was simulated by solving the corresponding diffusion equation with moving boundary conditions. From the analysis of the experimental data we determined the mean distance and size of the nanoparticles and confirmed the validity of the ? t1/3 growth law following from the Lifshitz Slyozov-Wagner theory. From a detailed comparison of the experimental data with simulations we also assessed the diffusion coefficient of the impurity atoms and its activation energy. PMID- 29176929 TI - Family Drawings before and after Treatment for Child Conduct Problems: Fluidity of Family Dysfunction. AB - Children's drawings have previously been found to reflect their representations of family relationships. The present study examined whether evidence-based parent training for child conduct problems impacts on representations of family functioning using the Family Drawing Paradigm (FDP). N = 53 clinic-referred children (aged 3-15) with conduct problems and their families were assessed pre treatment and at 6-month follow-up on a modified version of the FDP. Analyses of changes in the FDP revealed improvements in family functioning but not tone of language (as indicated by written descriptors) following treatment. Higher family dysfunction scores were associated with increased levels of callous-unemotional (CU) traits in the children pre-treatment. Children with high levels of CU, however, demonstrated greater change in FDP dysfunction than a low CU group, resulting in similar levels at follow-up. CU traits also moderated the association between change in family warmth and conduct problem severity, with increased FDP warmth more strongly related to improved conduct problems in the high vs. the low CU group. FDP drawings are sensitive to changes in family functioning arising from parent training, accounting for unique variance in child outcomes independent of verbal reports. PMID- 29176927 TI - Conceptualizing Eukaryotic Metabolic Sensing and Signaling. AB - For almost all cells, nutrient availability, from glucose to amino acids, dictates their growth or developmental programs. This nutrient availability is closely coupled to the overall intracellular metabolic state of the cell. Therefore, cells have evolved diverse, robust and versatile modules to sense intracellular metabolic states, activate signaling outputs and regulate outcomes to these states. Yet, signaling and metabolism have been viewed as important but separate. This short review attempts to position aspects of intracellular signaling from a metabolic perspective, highlighting how conserved, core principles of metabolic sensing and signaling can emerge from an understanding of metabolic regulation. I briefly explain the nature of metabolic sensors, using the example of the AMP activated protein kinase (AMPK) as an "energy sensing" hub. Subsequently, I explore how specific central metabolites, particularly acetyl-CoA, but also S -adenosyl methionine and SAICAR, can act as signaling molecules. I extensively illustrate the nature of a metabolic signaling hub using the specific example of the Target of Rapamycin Complex 1 (TORC1), and amino acid sensing. A highlight is the emergence of the lysosome/vacuole as a metabolic and signaling hub. Finally, the need to expand our understanding of the intracellular dynamics (in concentration and localization) of several metabolites, and their signaling hubs is emphasized. PMID- 29176931 TI - On the Use of Summary Comorbidity Measures for Prognosis and Survival Treatment Effect Estimation. AB - Prognostic scores have been proposed as outcome based confounder adjustment scores akin to propensity scores. However, prognostic scores have not been widely used in the substantive literature. Instead, comorbidity scores, which are limited versions of prognostic scores, have been used extensively by clinical and health services researchers. A comorbidity is an existing disease an individual has in addition to a primary condition of interest, such as cancer. Comorbidity scores are used to reduce the dimension of a vector of comorbidity variables into a single scalar variable. Such scores are often added to regression models with other non-comorbidity variables such as age and sex, both for analyzing prognosis and for confounder adjustment when analyzing treatment effects. Despite their widespread use, the properties of and conditions under which comorbidity scores are valid dimension reduction tools in statistical models is largely unknown. In this article, we show that under relatively standard assumptions, comorbidity scores can have equal prognostic and confounder-adjustment abilities as the individual comorbidity variables, but that biases can occur if there are additional effects, such as interactions, of covariates beyond that captured by the comorbidity score. Simulations were performed to illustrate empirical properties and a data example using breast cancer data from the SEER Medicare Database demonstrates the application of these results. PMID- 29176932 TI - Advanced nurse practitioners in municipal healthcare as a way to meet the growing healthcare needs of the frail elderly: a qualitative interview study with managers, doctors and specialist nurses. AB - Background: The number of frail elderly people with complex nursing and medical care needs is increasing, and consequently, the healthcare burden. The implementation of Advanced Nurse Practitioners globally has been shown to make healthcare more effective and increase patient safety, continuity of care and access to care. In Sweden, research about Advanced Nurse Practitioners is limited. Thus, this study aimed to investigate the opinions of managers, doctors and nurses in primary care and municipal healthcare about the role of ANPs in municipal healthcare as a way to meet the increasing healthcare needs of the frail elderly. Methods: Managers, doctors and specialist nurses in primary care and municipal healthcare adopted a qualitative, descriptive design through 12 semi-structured interviews. The data were analysed using content analysis. Results: The participants expressed both opportunities as well as challenges with Advanced Nurse Practitioners in municipal healthcare. This role considered to satisfy frail elderly people's healthcare needs and making the healthcare more effective as the doctors would have more time for other patients. The challenges mainly consist of doubts from the managers whether the nurses would be motivated to pursue further education to become an Advanced Nurse Practitioner if the role becomes a reality. The doctors were unsure if the nurses would consider taking the responsibility the role would imply. Conclusions: Advanced Nurse Practitioner is considered to be a valuable resource not only for the frail elderly but also for the nurses in the municipal healthcare and for the doctors in primary care as they probably would make healthcare more effective. They might be a way to meet the increasing healthcare needs of frail elderly, however there are also challenges to overcome before they can become a reality in a Swedish healthcare context. Consequently, this role deserves further investigation. PMID- 29176933 TI - A clinical pathway for the management of difficult venous access. AB - Background: Many patients are admitted to hospital with non-visible or palpable veins, often resulting in multiple painful attempts at cannulation, anxiety and catheter failure. We developed a difficult intravenous pathway at our institution to reduce the burden of difficult access for patients by increasing first attempt success with ultrasound guidance. The emphasis was to provide a solution for hospitalised patients after business hours by training the after-hours clinical support team in ultrasound guided cannulation. Methods: Inception cohort study of patients referred to the after-hours clinical support team including outcomes such as number of attempts at cannulation before and after referral, insertion site, type of device inserted and recorded pain score for attempts prior to referral and for attempts by the after-hours clinical support team. Results: Between January and December 2016, 379 patients were referred to the after-hours clinical support team for placement of a peripheral intravenous catheter under ultrasound guidance. The median number of unsuccessful attempts before referral was 2 (IQR 2, 4), this ranged between 1 attempt to 10 attempts compared to only 1 attempt (IQR 1, 1, p < 0.001) with no more than 2 attempts in total by the after hours clinical support team. The first time success rate by the after-hours clinical support team was 93% (n = 348). The median pain score for attempts with ultrasound use was 2/10 (IQR 1-3) compared to 7/10 (IQR 5-9) for previous attempts without ultrasound (p < 0.001). Conclusion: The use of ultrasound guidance for peripheral intravenous catheter insertion by the after-hours clinical support team for patients with difficult venous access has been successful at our institution with 9 out of every 10 catheters inserted at first attempt with significantly lower recorded pain scores. PMID- 29176934 TI - Nurses' competencies in home healthcare: an interview study. AB - Background: Nurses working in Home healthcare (HHC) are facing major challenges since more advanced care and treatment are increasingly being carried out in patients' homes. The aim of this study has been to explore how nurses experience their competencies in HHC situations. Methods: This study has a qualitative and explorative design. Ten nurses were interviewed and data was analyzed using content analysis. Results: The themes "Being a capable nurse", "Being a useful nurse" and "Being a subordinate and dependent nurse" were identified. Nurses want to be capable of taking care of patients, to develop their competencies and to perform their duties in the way required. They also want their work to be useful and to provide good and safe HHC. Finally, nurses want to improve HHC care by applying their competencies. Simultaneously, they are subordinate and dependent in relation to their manager and also dependent upon their manager's interest in encouraging nurses' competence development. Conclusions: Nurses in HHC are responsible for many seriously ill patients and they want to contribute to good and safe patient care. To maintain patient safety, reduce the risk for burnout and staff turnover as well as to contribute to a sustainable development of the work, strategies for transferring competencies between nurses and efforts for competence development are needed. PMID- 29176935 TI - Restoration of miR-29b exerts anti-cancer effects on glioblastoma. AB - Background: Glioblastoma multiforme (GBM) is known as one of the most fatal forms of cancer. MicroRNAs have been widely implicated in the regulation of mammalian development and pathogenesis. The brain-enriched miR-29 subfamilies are known to be exclusively expressed in the developing brain, and they are aberrantly down regulated in GBM. This study aims to elucidate the role of miR-29b in GBM development and the feasibility of therapeutic targeting using conjugated nanoparticles. Methods: After confirmation of miR-29b expression levels in GBM tissues by analysis of open source data, the anticancer effect of miR-29b was tested by the introduction of syn-hsa-miR-29b-3p in the A172 GBM cell line. In vitro studies of cell viability and apoptosis and ex vivo study using GBM tissue slice cultures from 3 patients and nanoparticle delivery of miR-29b were performed. Results: We discovered an increase in apoptotic cell populations with the introduction of miR-29b in the GBM cell line. An established human-derived GBM tissue slice culture system confirmed the anticancer effect of miR-29b conjugated nanoparticles. Using PCR array, we found that exogenous miR-29b inhibits the expression of COL1A2, COL3A1, COL4A1, ELN, ITGA11, MMP24, and SPARC, which mediates an anticancer effect. Conclusions: miR-29b may serve as a putative therapeutic molecule when its expression is restored using a nanoparticle delivery system in GBM. PMID- 29176936 TI - Role of microRNA-33a in regulating the expression of PD-1 in lung adenocarcinoma. AB - Background: MiRNAs are vital in functioning as either oncogenes or tumor suppressors in the cell cycle. Target transcripts for immune checkpoint molecules such as PD-1/PD-L1 and (programmed cell death-1/its ligand and cytotoxic T lymphocyte antigen 4) have proven to be beneficial against several solid tumors, including lung adenocarcinoma. Methods: Simultaneous quantification of the expression level of miR-33a and PD-1, PD-L1 and CTLA4 mRNAs with NanoString technology was performed in 88 lung adenocarcinoma specimens. A cohort of 323 lung adenocarcinoma patients from the cancer genome atlas (TCGA) database was further analyzed, in order to test our hypothesis. Potential interference of PD 1, PD-L1 and CTLA4 gene expression by miR-33a was predicted using the microRNA target prediction program RNA22. Results: High miR-33a expression was significantly associated with younger (p = 0.005), female (p = 0.04), patients with low grade (p < 0.0001), early stage (p = 0.03) tumors, and better survival. The hypothesis of the involvement of miR-33a in PD-1/PD-L1/CTLA4 mechanisms was corroborated by the finding of putative miR-33a binding sites in all three genes using the RNA22 method. We found an inverse correlation between miR-33a and PD-1 levels (p = 0.01), as well as for PD-L1 (p = 0.01) and CTLA4 (p = 0.03) expression, and a significant better prognosis for patients with high miR-33a/low PD-1. TCGA database analysis confirmed that miR-33a high levels were associated with low PD-1 expression and with longer survival on a larger population. Conclusions: Our study emphasizes the notion of a potential value of miR-33a as a favorable prognostic marker through PD-1 regulation. PMID- 29176938 TI - A proteomic approach to understanding the pathogenesis of idiopathic macular hole formation. AB - Idiopathic macular holes (IMH) are full-thickness defects of retinal tissue that cause severe vision loss due to disruption of the anatomic fovea. Abnormal vitreous traction is involved in the formation of macular holes. Both glial cells and hyalocytes contribute to epiretinal membrane formation in IMH. In order to gain further insight into the pathophysiology of IMH, we conducted a discovery phase investigation of the vitreous proteome in four patients with macular holes and six controls using one-dimensional gel fractionation and liquid chromatography-tandem mass spectrometry analyses on an Orbitrap Elite mass spectrometer. Of a total of 5912 vitreous proteins, 32 proteins had increased and 39 proteins had decreased expression in IMH compared with controls, using a false discovery rate approach with p value < 0.001 and q value < 0.05. IMH was associated with increased expression of proteins in the complement pathway, alpha 2-macroglobulin, a major inducer of Muller glial cell migration, fibrinogen, and extracellular matrix proteins, and decreased expression of proteins involved in protein folding and actin filament binding. A proteomic approach revealed proteins and biological pathways that may be involved in the pathogenesis of IMH and could be targeted for future studies. PMID- 29176937 TI - Proteomic profiling identifies markers for inflammation-related tumor-fibroblast interaction. AB - Background: Cancer associated fibroblasts are activated in the tumor microenvironment and contribute to tumor progression, angiogenesis, extracellular matrix remodeling, and inflammation. Methods: To identify proteins characteristic for fibroblasts in colorectal cancer we used liquid chromatography-tandem mass spectrometry to derive protein abundance from whole-tissue homogenates of human colorectal cancer/normal mucosa pairs. Alterations of protein levels were determined by two-sided t test with greater than threefold difference and an FDR of < 0.05. Public available datasets were used to predict proteins of stromal origin and link protein with mRNA regulation. Immunohistochemistry confirmed the localization of selected proteins. Results: We identified a set of 24 proteins associated with inflammation, matrix organization, TGFbeta receptor signaling and angiogenesis mainly originating from the stroma. Most prominent were increased abundance of SerpinB5 in the parenchyme and latent transforming growth factor beta-binding protein, thrombospondin-B2, and secreted protein acidic-and-cysteine rich in the stroma. Extracellular matrix remodeling involved collagens type VIII, XII, XIV, and VI as well as lysyl-oxidase-2. In silico analysis of mRNA levels demonstrated altered expression in the tumor and the adjacent normal tissue as compared to mucosa of healthy individuals indicating that inflammatory activation affected the surrounding tissue. Immunohistochemistry of 26 tumor specimen confirmed upregulation of SerpinB5, thrombospondin B2 and secreted protein acidic and-cysteine-rich. Conclusions: This study demonstrates the feasibility of detecting tumor- and compartment-specific protein-signatures that are functionally meaningful by proteomic profiling of whole-tissue extracts together with mining of RNA expression datasets. The results provide the basis for further exploration of inflammation-related stromal markers in larger patient cohorts and experimental models. PMID- 29176939 TI - Views of Experienced Electronic Cigarette Users. AB - Background: Awareness and use of electronic cigarettes (e-cigs) has increased significantly in the last five years, but little is known about the experiences, satisfaction, opinions and preferences of e-cigs users. Method: 1177 participants completed an online survey about their electronic cigarette preferences, of which 200 were randomly selected for analysis. The data was analyzed using both qualitative and quantitative methods. Results: Participants found the design, the ability to customize, and the quality of vapor to be the most important characteristics of the device. Participants thought the most positive aspects of e-cig use were help to quit smoking, improved overall health, and reduced cost. The negative aspects associated with use were mainly related to side effects, such as dry mouth. When asked to explain how e-cigs were used differently than cigarettes, participants reported puffing more regularly, but taking fewer puffs per session. Conclusions: Experienced e-cig users stated that initiating e-cig use helped them to quit or reduce their conventional smoking, which they believe reduced their health risks. In comparison to cigarette smoking, e-cig users reported using their e-cig more times per day, but with fewer puffs at each use time. Users acknowledged that more research is needed to understand the safety and long-term effects of use. They mentioned dry mouth as a common side effect and common problems with reliability of e-cigs. Understanding these views may help health professionals to assess and assist e-cig users, and in the future, may help regulators to improve quality and reduce risks. PMID- 29176940 TI - Ultrafast Near-Infrared Light-triggered Intracellular Uncaging to Probe Cell Signaling. AB - The possibility of regulating cell signaling with high spatial and temporal resolution within individual cells and complex cellular networks has important implications in biomedicine. In this report, we demonstrate a general strategy that uses near-infrared tissue-penetrating laser pulses to uncage biomolecules from plasmonic gold-coated liposomes, i.e. plasmonic liposomes, to activate cell signaling in a non-thermal, ultrafast and highly controllable fashion. Near infrared picosecond laser pulse induces transient nanobubbles around plasmonic liposomes. The mechanical force generated from the collapse of nanobubbles rapidly ejects encapsulated compound within 0.1 ms. We showed that single pulse irradiation triggers the rapid intracellular uncaging of calcein from plasmonic liposomes inside endo-lysosomes. The uncaged calcein then evenly distributes over the entire cytosol and nucleus. Furthermore, we demonstrated the ability to trigger calcium signaling in both an immortalized cell line and primary dorsal root ganglion (DRG) neurons by intracellular uncaging of inositol triphosphate (IP3), an endogenous cell calcium signaling second messenger. Compared with other uncaging techniques, this ultrafast near-infrared light-driven molecular uncaging method is easily adaptable to deliver a wide range of bioactive molecules with an ultrafast optical switch, enabling new possibilities to investigate signaling pathways within individual cells and cellular networks. PMID- 29176941 TI - Perceptual Decisions in the Presence of Relevant and Irrelevant Sensory Evidence. AB - Perceptual decisions in the presence of decision-irrelevant sensory information require a selection of decision-relevant sensory evidence. To characterize the mechanism that is responsible for separating decision-relevant from irrelevant sensory information we asked human subjects to make judgments about one of two simultaneously present motion components in a random dot stimulus. Subjects were able to ignore the decision-irrelevant component to a large degree, but their decisions were still influenced by the irrelevant sensory information. Computational modeling revealed that this influence was not simply the consequence of subjects forgetting at times which stimulus component they had been instructed to base their decision on. Instead, residual irrelevant information always seems to be leaking through, and the decision process is captured by a net sensory evidence signal being accumulated to a decision threshold. This net sensory evidence is a linear combination of decision-relevant and irrelevant sensory information. The selection process is therefore well described by a strong linear gain modulation, which, in our experiment, resulted in the relevant sensory evidence having at least 10 times more impact on the decision than the irrelevant evidence. PMID- 29176942 TI - Cognitive Decline in Neuronal Aging and Alzheimer's Disease: Role of NMDA Receptors and Associated Proteins. AB - Molecular changes associated with neuronal aging lead to a decrease in cognitive capacity. Here we discuss these alterations at the level of brain regions, brain cells, and brain membrane and cytoskeletal proteins with an special focus in NMDA molecular changes through aging and its effect in cognitive decline and Alzheimer disease. Here, we propose that some neurodegenerative disorders, like Alzheimer's disease (AD), are characterized by an increase and acceleration of some of these changes. PMID- 29176943 TI - Deployment of Mobile EEG Technology in an Art Museum Setting: Evaluation of Signal Quality and Usability. AB - Electroencephalography (EEG) has emerged as a powerful tool for quantitatively studying the brain that enables natural and mobile experiments. Recent advances in EEG have allowed for the use of dry electrodes that do not require a conductive medium between the recording electrode and the scalp. The overall goal of this research was to gain an understanding of the overall usability and signal quality of dry EEG headsets compared to traditional gel-based systems in an unconstrained environment. EEG was used to collect Mobile Brain-body Imaging (MoBI) data from 432 people as they experienced an art exhibit in a public museum. The subjects were instrumented with either one of four dry electrode EEG systems or a conventional gel electrode EEG system. Each of the systems was evaluated based on the signal quality and usability in a real-world setting. First, we describe the various artifacts that were characteristic of each of the systems. Second, we report on each system's usability and their limitations in a mobile setting. Third, to evaluate signal quality for task discrimination and characterization, we employed a data driven clustering approach on the data from 134 of the 432 subjects (those with reliable location tracking information and usable EEG data) to evaluate the power spectral density (PSD) content of the EEG recordings. The experiment consisted of a baseline condition in which the subjects sat quietly facing a white wall for 1 min. Subsequently, the participants were encouraged to explore the exhibit for as long as they wished (piece-viewing). No constraints were placed upon the individual in relation to action, time, or navigation of the exhibit. In this freely-behaving approach, the EEG systems varied in their capacity to record characteristic modulations in the EEG data, with the gel-based system more clearly capturing stereotypical alpha and beta-band modulations. PMID- 29176944 TI - Elucidating Sensorimotor Control Principles with Myoelectric Musculoskeletal Models. AB - There is an old saying that you must walk a mile in someone's shoes to truly understand them. This mini-review will synthesize and discuss recent research that attempts to make humans "walk a mile" in an artificial musculoskeletal system to gain insight into the principles governing human movement control. In this approach, electromyography (EMG) is used to sample human motor commands; these commands serve as inputs to mathematical models of muscular dynamics, which in turn act on a model of skeletal dynamics to produce a simulated motor action in real-time (i.e., the model's state is updated fast enough produce smooth motion without noticeable transitions; Manal et al., 2002). In this mini-review, these are termed myoelectric musculoskeletal models (MMMs). After a brief overview of typical MMM design and operation principles, the review will highlight how MMMs have been used for understanding human sensorimotor control and learning by evoking apparent alterations in a user's biomechanics, neural control, and sensory feedback experiences. PMID- 29176945 TI - Sound-Evoked Biceps Myogenic Potentials Reflect Asymmetric Vestibular Drive to Spastic Muscles in Chronic Hemiparetic Stroke Survivors. AB - Aberrant vestibular nuclear function is proposed to be a principle driver of limb muscle spasticity after stroke. We sought to determine whether altered cortical modulation of descending vestibulospinal pathways post-stroke could impact the excitability of biceps brachii motoneurons. Twelve chronic hemispheric stroke survivors aged 46-68 years were enrolled. Sound evoked biceps myogenic potentials (SEBMPs) were recorded from the spastic and contralateral biceps muscles using surface EMG electrodes. We assessed the impact of descending vestibulospinal pathways on biceps muscle activity and evaluated the relationship between vestibular function and the severity of spasticity. Spastic SEBMP responses were recorded in 11/12 subjects. Almost 60% of stroke subjects showed evoked responses solely on the spastic side. These data strongly support the idea that vestibular drive is asymmetrically distributed to biceps motoneuron pools in hemiparetic spastic stroke survivors. This abnormal vestibular drive is very likely to be a factor mediating the striking differences in motoneuron excitability between the clinically affected and clinically spared sides. This study extends our previous observations on vestibular nuclear changes following hemispheric stroke and potentially sheds light on the underlying mechanisms of post-stroke spasticity. PMID- 29176946 TI - Individual Differences in Verbal and Spatial Stroop Tasks: Interactive Role of Handedness and Domain. AB - A longstanding debate in psychology concerns the relation between handedness and cognitive functioning. The present study aimed to contribute to this debate by comparing performance of right- and non-right-handers on verbal and spatial Stroop tasks. Previous studies have shown that non-right-handers have better inter-hemispheric interaction and greater access to right hemisphere processes. On this ground, we expected performance of right- and non-right-handers to differ on verbal and spatial Stroop tasks. Specifically, relative to right-handers, non right-handers should have greater Stroop effect in the color-word Stroop task, for which inter-hemispheric interaction does not seem to be advantageous to performance. By contrast, non-right-handers should be better able to overcome interference in the spatial Stroop task. This is for their preferential access to the right hemisphere dealing with spatial material and their greater inter hemispheric interaction with the left hemisphere hosting Stroop task processes. Our results confirmed these predictions, showing that handedness and the underlying brain asymmetries may be a useful variable to partly explain individual differences in executive functions. PMID- 29176947 TI - Cortical Contribution to Linear, Non-linear and Frequency Components of Motor Variability Control during Standing. AB - Motor variability is an inherent feature of all human movements and reflects the quality of functional task performance. Depending on the requirements of the motor task, the human sensory-motor system is thought to be able to flexibly govern the appropriate level of variability. However, it remains unclear which neurophysiological structures are responsible for the control of motor variability. In this study, we tested the contribution of cortical cognitive resources on the control of motor variability (in this case postural sway) using a dual-task paradigm and furthermore observed potential changes in control strategy by evaluating Ia-afferent integration (H-reflex). Twenty healthy subjects were instructed to stand relaxed on a force plate with eyes open and closed, as well as while trying to minimize sway magnitude and performing a "subtracting-sevens" cognitive task. In total 25 linear and non-linear parameters were used to evaluate postural sway, which were combined using a Principal Components procedure. Neurophysiological response of Ia-afferent reflex loop was quantified using the Hoffman reflex. In order to assess the contribution of the H reflex on the sway outcome in the different standing conditions multiple mixed model ANCOVAs were performed. The results suggest that subjects were unable to further minimize their sway, despite actively focusing to do so. The dual-task had a destabilizing effect on PS, which could partly (by 4%) be counter-balanced by increasing reliance on Ia-afferent information. The effect of the dual-task was larger than the protective mechanism of increasing Ia-afferent information. We, therefore, conclude that cortical structures, as compared to peripheral reflex loops, play a dominant role in the control of motor variability. PMID- 29176948 TI - The Oncogenic Role of Tribbles 1 in Hepatocellular Carcinoma Is Mediated by a Feedback Loop Involving microRNA-23a and p53. AB - Hepatocellular carcinoma (HCC) is a common malignancy associated with a high risk of recurrence and metastasis and a poor prognosis. Here, we examined the involvement of the pseudokinase Tribbles 1 (TRIB1), a scaffold protein associated with several malignancies, in HCC and investigated the underlying mechanisms. TRIB1 was upregulated in HCC tissues and cell lines in correlation with low levels of p53. TRIB1 gain and loss of function experiments indicated that TRIB1 promoted HCC cell viability concomitant with the downregulation of p53, and induced HCC cell migration, invasion, and epithelial-mesenchymal transition. TRIB1 was identified as a target of microRNA-23a (miR-23a), and miR-23a overexpression downregulated TRIB1 and upregulated p53 in HCC cells. Ectopic expression of TRIB1 upregulated beta-catenin and its effectors c-myc and MMP-7 in a p53-dependent manner. TRIB1 silencing inhibited tumor growth and promoted apoptosis in vivo via a mechanism that would involve the modulation of p53 and beta-catenin signaling. The present results indicate that TRIB1 promotes HCC tumorigenesis and invasiveness via a feedback loop that involves the modulation of its expression by miR-23a with the likely downregulation of p53, and suggest the involvement of the beta-catenin signaling pathway. These findings suggest potential targets for the treatment of HCC and therefore merit further investigation.

PMID- 29176950 TI - Cardiovascular and Cutaneous Responses to the Combination of Alcohol and Soft Drinks: The Way to Orthostatic Intolerance? AB - Aim: Acute ingestion of alcohol is often accompanied by cardiovascular dysregulation, malaise and even syncope. The full hemodynamic and cutaneous responses to the combination of alcohol and sugar (i.e., alcopops), a common combination in young people, and the mechanisms for the propensity to orthostatic intolerance are not well established. Thus, the purpose of this study was to evaluate the cardiovascular and cutaneous responses to alcopops in young subjects. Methods: Cardiovascular and cutaneous responses were assessed in 24 healthy young subjects (12 men, 12 women) sitting comfortably and during prolonged active standing with a 30-min baseline and 130 min following ingestion of 400 mL of either: water, water + 48 g sugar, water + vodka (1.28 mL.kg-1 of body weight, providing 0.4 g alcohol.kg-1), water + sugar + vodka, according to a randomized cross-over design. Results: Compared to alcohol alone, vodka + sugar induced a lower breath alcohol concentration (BrAC), blood pressure and total peripheral resistance (p < 0.05), a higher cardiac output and heart rate (p < 0.05) both in sitting position and during active standing. In sitting position vodka + sugar consumption also led to a greater increase in skin blood flow and hand temperature (p < 0.05) and a decrease in baroreflex sensitivity (p < 0.05). We observed similar results between men and women both in sitting position and during active standing. Conclusion: Despite lower BrAC, ingestion of alcopops induced acute vasodilation and hypotension in sitting position and an encroach of the hemodynamic reserve during active standing. Even if subjects did not feel any signs of syncope these results could be of clinical importance with higher doses of alcohol or if combined to other hypotensive challenges. PMID- 29176952 TI - Modulation of Neurogenesis through the Promotion of Energy Production Activity Is behind the Antidepressant-Like Effect of Colonial Green Alga, Botryococcus braunii. AB - Algae have been recognized as important resources providing functional components due to their capacity to exert beneficial effects on health. Therefore, there is increasing interest in investigating the biological activity of algae. In this study, we evaluated the antidepressant-like effect of the administration of 100 mg/kg/day of the ethanol extract of colonial green alga Botryococcus braunii (EEB) for 14 consecutive days in the forced swimming test (FST)-induced depression in imprinting control region (ICR) mice. Imipramine, a commercial antidepressant drug, was used as a positive control. In addition, we investigated the molecular mechanisms underlying the effect of EEB by measuring ATP production and by assessing any change in gene expression at the end of the treatment using real-time polymerase chain reaction (PCR) and microarray assays. We showed that the immobility time in the water-administered control (FST stress) group gradually increased from day 1 to day 14. However, treatment with EEB caused a significant decrease of immobility time in the FST compared with that in the FST stress group. Microarray and real-time PCR results revealed that EEB treatment induced variation in the expression of several genes associated with neurogenesis, energy metabolism, and dopamine synthesis. Interestingly, we revealed that only EEB treatment enhanced the promotion of energy production, while treatment with imipramine was ineffective. Our study provides the first evidence that B. braunii enhances energy production, which may contribute to the modulation of neurogenesis and to the enhancement of dopaminergic function, in turn potentially underlying the antistress- and antidepressant-like effects that we observed. PMID- 29176951 TI - Much More than a Cardiotonic Steroid: Modulation of Inflammation by Ouabain. AB - Since the discovery of ouabain as a cardiotonic steroid hormone present in higher mammals, research about it has progressed rapidly and several of its physiological and pharmacological effects have been described. Ouabain can behave as a stress hormone and adrenal cortex is its main source. Direct effects of ouabain are originated due to the binding to its receptor, the Na+/K+-ATPase, on target cells. This interaction can promote Na+ transport blockade or even activation of signaling transduction pathways (e.g., EGFR/Src-Ras-ERK pathway activation), independent of ion transport. Besides the well-known effect of ouabain on the cardiovascular system and blood pressure control, compelling evidence indicates that ouabain regulates a number of immune functions. Inflammation is a tightly coordinated immunological function that is also affected by ouabain. Indeed, this hormone can modulate many inflammatory events such as cell migration, vascular permeability, and cytokine production. Moreover, ouabain also interferes on neuroinflammation. However, it is not clear how ouabain controls these events. In this brief review, we summarize the updates of ouabain effect on several aspects of peripheral and central inflammation, bringing new insights into ouabain functions on the immune system. PMID- 29176953 TI - Mitochondrial Proton Leak Compensates for Reduced Oxidative Power during Frequent Hypothermic Events in a Protoendothermic Mammal, Echinops telfairi. AB - The lesser hedgehog tenrec (Echinops telfairi) displays reptile-like thermoregulatory behavior with markedly high variability in body temperature and metabolic rate. To understand how energy metabolism copes with this flexibility, we studied the bioenergetics of isolated liver mitochondria from cold (20 degrees C) and warm (27 degrees C) acclimated tenrecs. Different acclimation temperatures had no impact on mitochondrial respiration using succinate as the substrate. Mimicking the variation of body temperature by changing assay temperatures from 22 to 32 degrees C highlighted temperature-sensitivity of respiration. The 40% reduction of respiratory control ratio (RCR) at 22 degrees C compared to 32 degrees C, a common estimate for mitochondrial efficiency, was caused by reduced substrate oxidation capacity. The simultaneous measurement of mitochondrial membrane potential enabled the precise assessment of efficiency with corrected respiration rates. Using this method, we show that proton leak respiration at the highest common membrane potential was not affected by acclimation temperature but was markedly decreased by assay temperature. Using membrane potential corrected respiration values, we show that the fraction of ATP-linked respiration (coupling efficiency) was maintained (70-85%) at lower temperatures. Collectively, we demonstrate that compromised substrate oxidation was temperature-compensated by the reduction of proton leak, thus maintaining the efficiency of mitochondrial energy conversion. Therefore, membrane potential data suggest that adjustments of mitochondrial proton leak contribute to energy homeostasis during thermoregulatory flexibility of tenrecs.

PMID- 29176955 TI - Affording Sustainability: Adopting a Theory of Affordances as a Guiding Heuristic for Environmental Policy. AB - Human behavior is an underlying cause for many of the ecological crises faced in the 21st century, and there is no escaping from the fact that widespread behavior change is necessary for socio-ecological systems to take a sustainable turn. Whilst making people and communities behave sustainably is a fundamental objective for environmental policy, behavior change interventions and policies are often implemented from a very limited non-systemic perspective. Environmental policy-makers and psychologists alike often reduce cognition 'to the brain,' focusing only to a minor extent on how everyday environments systemically afford pro-environmental behavior. Symptomatic of this are the widely prevalent attitude action, value-action or knowledge-action gaps, understood in this paper as the gulfs lying between sustainable thinking and behavior due to lack of affordances. I suggest that by adopting a theory of affordances as a guiding heuristic, environmental policy-makers are better equipped to promote policies that translate sustainable thinking into sustainable behavior, often self reinforcingly, and have better conceptual tools to nudge our socio-ecological system toward a sustainable turn. Affordance theory, which studies the relations between abilities to perceive and act and environmental features, is shown to provide a systemic framework for analyzing environmental policies and the ecology of human behavior. This facilitates the location and activation of leverage points for systemic policy interventions, which can help socio-ecological systems to learn to adapt to more sustainable habits. Affordance theory is presented to be applicable and pertinent to technically all nested levels of socio-ecological systems from the studies of sustainable objects and households to sustainable urban environments, making it an immensely versatile conceptual policy tool. Finally, affordance theory is also discussed from a participatory perspective. Increasing the fit between local thinking and external behavior possibilities entails a deep understanding of tacit and explicit attitudes, values, knowledge as well as physical and social environments, best gained via inclusive and polycentric policy approaches. PMID- 29176956 TI - Meta-analysis of the Age-Dependent Efficacy of Multiple Sclerosis Treatments. AB - Objective: To perform a meta-analysis of randomized, blinded, multiple sclerosis (MS) clinical trials, to test the hypothesis that efficacy of immunomodulatory disease-modifying therapies (DMTs) on MS disability progression is strongly dependent on age. Methods: We performed a literature search with pre-defined criteria and extracted relevant features from 38 clinical trials that assessed efficacy of DMTs on disability progression. We fit a linear regression, weighted for trial sample size, and duration, to examine the hypothesis that age has a defining effect on the therapeutic efficacy of immunomodulatory DMTs. Results: More than 28,000 MS subjects participating in trials of 13 categories of immunomodulatory drugs are included in the meta-analysis. The efficacy of immunomodulatory DMTs on MS disability strongly decreased with advancing age (R2 = 0.6757, p = 6.39e-09). Inclusion of baseline EDSS did not significantly improve the model. The regression predicts zero efficacy beyond approximately age 53 years. The comparative efficacy rank derived from the regression residuals differentiates high- and low-efficacy drugs. High-efficacy drugs outperform low efficacy drugs in inhibiting MS disability only for patients younger than 40.5 years. Conclusion: The meta-analysis supports the notion that progressive MS is simply a later stage of the MS disease process and that age is an essential modifier of a drug efficacy. Higher efficacy treatments exert their benefit over lower efficacy treatments only during early stages of MS, and, after age 53, the model suggests that there is no predicted benefit to receiving immunomodulatory DMTs for the average MS patient. PMID- 29176957 TI - Manual Dexterity and Intralimb Coordination Assessment to Distinguish Different Levels of Impairment in Boccia Players with Cerebral Palsy. AB - Background: Boccia is a paralympic sport played by athletes with severe neurological impairments affecting all four limbs. Impaired manual dexterity (MD) and intralimb coordination (ILC) may limit individuals' ability to perform certain activities such as grasping, releasing, or manipulating objects, which are essential tasks for daily life or to participate in para sports such as boccia. However, there are currently no specific instruments available to assess hand-arm coordination in boccia players with severe cerebral palsy (CP). Purpose: To design new sport-specific coordination tests to assess impaired MD and ILC in boccia players; afterward, quantify to what extent their coordination is impaired compared to a control group (CG) without neurological impairments. Methods: Seventy-three recreational boccia players with severe CP (BC1: age = 34.01 +/- 16.43 years; BC2: age = 33.97 +/- 14.29 years), and 19 healthy adults (age = 27.89 +/- 7.08 years) completed the test battery. The Box and Block test (BBT) and Box and Ball test (BBLT) were used to assess MD and four tapping tests to assess upper ILC. Results: Both MD tests were able to discriminate between sport classes. Boccia players obtained better scores in the BBLT in comparison to the BBT, showing that the BBLT had more appropriate testing features. On the other hand, only one of the ILC tests was able to discriminate between sport classes, displaying the highest practical significance (d = -1.12). Participants with CP scored significantly worse in all the coordination tests compared to the CG. Conclusion: Using sport-specific equipment facilitated grasp function during the MD assessment. Regarding the ILC, the type of movement (continuous vs. discrete) seems to be more relevant for classification than the movement direction (vertical vs. horizontal) or the presence of a ball. PMID- 29176958 TI - New Multiple Sclerosis Disease Severity Scale Predicts Future Accumulation of Disability. AB - The search for the genetic foundation of multiple sclerosis (MS) severity remains elusive. It is, in fact, controversial whether MS severity is a stable feature that predicts future disability progression. If MS severity is not stable, it is unlikely that genotype decisively determines disability progression. An alternative explanation tested here is that the apparent instability of MS severity is caused by inaccuracies of its current measurement. We applied statistical learning techniques to a 902 patient-years longitudinal cohort of MS patients, divided into training (n = 133) and validation (n = 68) sub-cohorts, to test four hypotheses: (1) there is intra-individual stability in the rate of accumulation of MS-related disability, which is also influenced by extrinsic factors. (2) Previous results from observational studies are negatively affected by the insensitive nature of the Expanded Disability Status Scale (EDSS). The EDSS-based MS Severity Score (MSSS) is further disadvantaged by the inability to reliably measure MS onset and, consequently, disease duration (DD). (3) Replacing EDSS with a sensitive scale, i.e., Combinatorial Weight-Adjusted Disability Score (CombiWISE), and substituting age for DD will significantly improve predictions of future accumulation of disability. (4) Adjusting measured disability for the efficacy of administered therapies and other relevant external features will further strengthen predictions of future MS course. The result is a MS disease severity scale (MS-DSS) derived by conceptual advancements of MSSS and a statistical learning method called gradient boosting machines (GBM). MS-DSS greatly outperforms MSSS and the recently developed Age Related MS Severity Score in predicting future disability progression. In an independent validation cohort, MS-DSS measured at the first clinic visit correlated significantly with subsequent therapy-adjusted progression slopes (r = 0.5448, p = 1.56e-06) measured by CombiWISE. To facilitate widespread use of MS-DSS, we developed a free, interactive web application that calculates all aspects of MS-DSS and its contributing scales from user-provided raw data. MS-DSS represents a much-needed tool for genotype-phenotype correlations, for identifying biological processes that underlie MS progression, and for aiding therapeutic decisions. PMID- 29176959 TI - Gender-Specific Relationship between Obesity and Major Depression. AB - Objective: Prior research suggests a bidirectional relationship between obesity and major depressive disorder (MDD), but the results have been heterogeneous. Differences between males and females in the association of MDD with obesity may contribute to inconsistent results. Thus, this study was designed to determine whether sex has a differential effect on the relationship between MDD and obesity, and to explore the potential mechanisms. Methods: All participants were diagnosed with MDD, and depression severity was measured using the 17-item Hamilton Depression Rating Scale. Body weight and height were measured to calculate body mass index (BMI). Body composition, including total fat, trunk fat, android fat, and visceral fat mass, was measured by dual-energy X-ray absorptiometry. Subjects provided blood samples, and serum was extracted for measuring the inflammatory factors using human immunoassay kits. Results: Among all obesity measures, depressed women had greater BMI and total body fat. By contrast, depressed men had greater visceral fat mass. However, only in depressed women was depression correlated with several measures of obesity, including BMI, total body fat, and visceral fat mass. A stepwise multiple regression analysis was conducted, and only visceral fat entered the regression model and was most predictive of depression in women (beta = 0.60, p = 0.007). Moreover, compared with depressed men, depressed women had higher leptin levels after controlling for BMI, total body fat, and visceral fat. Conclusion: These results highlight gender differences in determining the association between obesity and depression, and elevated leptin level is a potential mechanism linking MDD to obesity in depressed women. Understanding a gender-specific relationship between obesity and MDD would allow clinicians to target and personalize therapies in the hope of improving health outcomes. PMID- 29176961 TI - Clinical and Biochemical Associations with Diabetic Retinopathy in Male Patients in the Gaza Strip. AB - Background: There are limited data on the prevalence and risk factors for diabetic retinopathy (DR) in the Gaza Strip. Objective: To assesses clinical and biochemical associated with DR in males with type 2 diabetes mellitus (T2DM) in the Gaza Strip. Methods: One hundred and fifty males with T2DM from the Gaza Strip underwent a questionnaire interview, serum biochemical analysis, and assessment of their previous urine and blood results. Results: The prevalence of DR was 24.7%. The duration of diabetes and prevalence of neuropathy, nephropathy, cardiovascular disease, and recurrent infections were significantly higher among patients with DR compared with those without DR (p < 0.05). Serum urea, creatinine, glucose, cholesterol, and low-density lipoprotein cholesterol were significantly elevated, whilst eGFR and high-density lipoprotein cholesterol were significantly lower in patients with DR compared with patients without DR (p < 0.05). Urinary albumin concentration and albumin creatinine ratio (ACR) was higher in patients with DR. ACR correlated significantly with the duration of T2DM (r = 0.311, p < 0.001), glucose (r = 0.479, p < 0.001), urea (r = 0.337, p < 0.001), creatinine (r = 0.275, p = 0.001), and GFR (r = -0.275, p < 0.001). Conclusion: These data show a high prevalence of DR in an unselected cohort of patients with T2DM and relationships to modifiable risk factors in Gaza. PMID- 29176963 TI - The Patterns and Drivers of Bacterial and Fungal beta-Diversity in a Typical Dryland Ecosystem of Northwest China. AB - Dryland ecosystems cover more than 30% of the terrestrial area of China, while processes that shape the biogeographic patterns of bacterial and fungal beta diversity have rarely been evaluated synchronously. To compare the biogeographic patterns and its drivers of bacterial and fungal beta-diversity, we collected 62 soil samples from a typical dryland region of northwest China. We assessed bacterial and fungal communities by sequencing bacterial 16S rRNA gene and fungal ITS data. Meanwhile, the beta-diversity was decomposed into two components: species replacement (species turnover) and nestedness to further explore the bacterial and fungal beta-diversity patterns and its causes. The results show that both bacterial and fungal beta-diversity were derived almost entirely from species turnover rather than from species nestedness. Distance-decay relationships confirmed that the geographic patterns of bacterial and fungal beta diversity were significantly different. Environmental factors had the dominant influence on both the bacterial and fungal beta-diversity and species turnover, however, the role of geographic distance varied across bacterial and fungal communities. Furthermore, both bacterial and fungal nestedness did not significantly respond to the environmental and geographic distance. Our findings suggest that the different response of bacterial and fungal species turnover to dispersal limitation and other, unknown processes may result in different biogeographic patterns of bacterial and fungal beta-diversity in the drylands of northwest China. Together, we highlight that the drivers of beta-diversity patterns vary between bacterial and fungal communities, and microbial beta diversity are driven by multiple factors in the drylands of northwest China. PMID- 29176962 TI - E2F1, a Novel Regulator of Metabolism. AB - In the past years, several lines of evidence have shown that cell cycle regulatory proteins also can modulate metabolic processes. The transcription factor E2F1 is a central player involved in cell cycle progression, DNA-damage response, and apoptosis. Its crucial role in the control of cell fate has been extensively studied and reviewed before; however, here, we focus on the participation of E2F1 in the regulation of metabolism. We summarize recent findings about the cell cycle-independent roles of E2F1 in various tissues that contribute to global metabolic homeostasis and highlight that E2F1 activity is increased during obesity. Finally, coming back to the pivotal role of E2F1 in cancer development, we discuss how E2F1 links cell cycle progression with different metabolic adaptations required for cell growth and survival. PMID- 29176964 TI - Only Acyl Carrier Protein 1 (AcpP1) Functions in Pseudomonas aeruginosa Fatty Acid Synthesis. AB - The genome of Pseudomonas aeruginosa contains three open reading frames, PA2966, PA1869, and PA3334, which encode putative acyl carrier proteins, AcpP1, AcpP2, and AcpP3, respectively. In this study, we found that, although these apo-ACPs were successfully phosphopantetheinylated by P. aeruginosa phosphopantetheinyl transferase (PcpS) and all holo-forms of these proteins could be acylated by Vibrio harveyi acyl-ACP synthetase (AasS), only AcpP1 could be used as a substrate for the synthesis of fatty acids, catalyzed by P. aeruginosa cell free extracts in vitro, and only acpP1 gene could restore growth in the Escherichia coliacpP mutant strain CY1877. And P. aeruginosaacpP1 could not be deleted, while disruption of acpP2 or acpP3 in the P. aeruginosa genome allowed mutant strains to grow as well as the wild type strain. These findings confirmed that only P. aeruginosa AcpP1 functions in fatty acid biosynthesis, and that acpP2 and acpP3 do not play roles in the fatty acid synthetic pathway. Moreover, disruption of acpP2 and acpP3 did not affect the ability of P. aeruginosa to produce N acylhomoserine lactones (AHL), but replacement of P. aeruginosaacpP1 with E. coliacpP caused P. aeruginosa to reduce the production of AHL molecules, which indicated that neither P. aeruginosa AcpP2 nor AcpP3 can act as a substrate for synthesis of AHL molecules in vivo. Furthermore, replacement of acpP1 with E. coliacpP reduced the ability of P. aeruginosa to produce some exo-products and abolished swarming motility in P. aeruginosa. PMID- 29176965 TI - Down Modulation of Host Immune Response by Amino Acid Repeats Present in a Trypanosoma cruzi Ribosomal Antigen. AB - Several antigens from Trypanosoma cruzi, the causative agent of Chagas disease (CD), contain amino acid repeats identified as targets of the host immune response. Ribosomal proteins containing an Ala, Lys, Pro-rich repeat domain are among the T. cruzi antigens that are strongly recognized by antibodies from CD patients. Here we investigated the role of amino acid repeats present in the T. cruzi ribosomal protein L7a, by immunizing mice with recombinant versions of the full-length protein (TcRpL7a), as well as with truncated versions containing only the repetitive (TcRpL7aRep) or the non-repetitive domains (TcRpL7aDeltaRep). Mice immunized with full-length TcRpL7a produced high levels of IgG antibodies against the complete protein as well as against the repeat domain, whereas mice immunized with TcRpL7aDeltaRep or TcRpL7aRep produced very low levels or did not produce IgG antibodies against this antigen. Also in contrast to mice immunized with the full-length TcRpL7a, which produced high levels of IFN-gamma, only low levels of IFN-gamma or no IFN-gamma were detected in cultures of splenocytes derived from mice immunized with truncated versions of the protein. After challenging with trypomastigotes, mice immunized with the TcRpL7a were partially protected against the infection whereas immunization with TcRpL7aDeltaRep did not alter parasitemia levels compared to controls. Strikingly, mice immunized with TcRpL7aRep displayed an exacerbated parasitemia compared to the other groups and 100% mortality after infection. Analyses of antibody production in mice that were immunized with TcRpL7aRep prior to infection showed a reduced humoral response to parasite antigens as well as against an heterologous antigen. In vitro proliferation assays with mice splenocytes incubated with different mitogens in the presence of TcRpL7aRep resulted in a drastic inhibition of B-cell proliferation and antibody production. Taken together, these results indicate that the repeat domain of TcRpL7a acts as an immunosuppressive factor that down regulates the host B-cell response against parasite antigens favoring parasite multiplication in the mammalian host. PMID- 29176960 TI - From Sea to Shining Sea and the Great Plains to Patagonia: A Review on Current Knowledge of Diabetes Mellitus in Hispanics/Latinos in the US and Latin America. AB - The past two decades have witnessed many advances in the prevention, treatment, and control of diabetes mellitus (DM) and its complications. Increased screening has led to a greater recognition of type 2 diabetes mellitus (type 2 DM) and prediabetes; however, Hispanics/Latinos, the largest minority group in the US, have not fully benefited from these advances. The Hispanic/Latino population is highly diverse in ancestries, birth places, cultures, languages, and socioeconomic backgrounds, and it populates most of the Western Hemisphere. In the US, the prevalence of DM varies among Hispanic/Latino heritage groups, being higher among Mexicans, Puerto Ricans, and Dominicans, and lower among South Americans. The risk and prevalence of diabetes among Hispanics/Latinos are significantly higher than in non-Hispanic Whites, and nearly 40% of Hispanics/Latinos with diabetes have not been formally diagnosed. Despite these striking facts, the representation of Hispanics/Latinos in pharmacological and non-pharmacological clinical trials has been suboptimal, while the prevalence of diabetes in these populations continues to rise. This review will focus on the epidemiology, etiology and prevention of type 2 DM in populations of Latin American origin. We will set the stage by defining the terms Hispanic, Latino, and Latin American, explaining the challenges identifying Hispanics/Latinos in the scientific literature and databases, describing the epidemiology of diabetes including type 2 DM and gestational diabetes mellitus (GDM)-and cardiovascular risk factors in Hispanics/Latinos in the US and Latin America, and discussing trends, and commonalities and differences across studies and populations, including methodology to ascertain diabetes. We will discuss studies on mechanisms of disease, and research on prevention of type 2 DM in Hispanics/Latinos, including women with GDM, youth and adults; and finalize with a discussion on lessons learned and opportunities to enhance research, and, consequently, clinical care oriented toward preventing type 2 DM in Hispanics/Latinos in the US and Latin America. PMID- 29176966 TI - Induction of Tyrosine Phosphorylation of UV-Activated EGFR by the Beta-Human Papillomavirus Type 8 E6 Leads to Papillomatosis. AB - Epidemiological evidence is accumulating that beta-human papillomaviruses (HPV) synergize with UV-light in the development of precancerous actinic keratosis, and cutaneous squamous cell carcinomas (cSCC), one of the most common cancers in the Caucasian population. We previously demonstrated the tumorigenic activity of beta HPV type 8 (HPV8) in the skin of transgenic mice and its cooperation with UV light. Analysis of underlying mechanisms now showed that in keratinocytes expressing the HPV8E6 protein a transient increase of tyrosine phosphorylated epidermal growth factor receptor (EGFR) in response to UV-irradiation occurred, while EGFR tyrosine phosphorylation, i.e., receptor tyrosine kinase (RTK) activity was hardly affected in empty vector control cells. FACS and immunofluorescences revealed that the EGFR was internalized into early endosomes in response to UV-exposure in both, HPV8E6 positive and in control cells, yet with a higher rate in the presence of HPV8E6. Moreover, only in HPV8E6 expressing keratinocytes the EGFR was further sorted into CD63+ intraluminal vesicles, indicative for trafficking to late endosomes. The latter requires the ubiquitination of the EGFR, and in correlation, we could show that only in HPV8E6 positive keratinocytes the EGFR was ubiquitinated upon UV-exposure. HPV8E6 and tyrosine phosphorylated EGFR directly interacted which was enhanced by UV irradiation. The treatment of K14-HPV8E6 transgenic mice with Canertinib, an inhibitor of the RTK-activity of the EGFR, suppressed skin papilloma growth in response to UV-irradiation. This confirms the crucial role of the RTK-activity of the EGFR in HPV8E6 and UV-mediated papillomatosis in transgenic mice. Taken together, our results demonstrate that HPV8E6 alters the signaling of the UV activated EGFR and this is a critical step in papilloma formation in response to UV-light in transgenic mice. Our results provide a molecular basis how a beta-HPV type may support early steps of skin tumor formation in cooperation with UV light. PMID- 29176967 TI - Reporter-Based Assays for High-Throughput Drug Screening against Mycobacterium abscessus. AB - Mycobacterium abscessus is a non-tuberculous mycobacterium that causes pulmonary and non-pulmonary infections. M. abscessus is resistant to many chemotherapeutic agents and the current treatment options show poor clinical outcomes. Thus, there is a dire need to find new antimicrobials effective at killing M. abscessus. Screening drug libraries to identify potential antimicrobials has been impeded by the lack of validated HTS assays for M. abscessus. In this study, we developed two 384-well high-throughput screening assays using fluorescent and bioluminescent reporter strains of M. abscessus for drug discovery. Optimization of inoculum size, incubation time and the volume-per-well based on Z-factor and signal intensity yielded two complementary, robust tools for M. abscessus drug discovery with Z-factor > 0.8. The MIC of known drugs, amikacin and clarithromycin, as determined by bioluminescence was in agreement with the published MIC values. A proof-of-concept screen of 2,093 natural product-inspired compounds was conducted using the 384-well bioluminescent assay to identify novel scaffolds active against M. abscessus. Five active "hit" compounds identified in this pilot screen were confirmed and characterized by a CFU assay and MIC determination. Overall, we developed and validated a 384-well screen that offers simple, sensitive and fast screening of compounds for activity against this emerging pathogen. To our knowledge, this is the first reporter-based high throughput screening study aimed at M. abscessus drug discovery. PMID- 29176968 TI - Uninterrupted Expression of CmSIT1 in a Sclerotial Parasite Coniothyrium minitans Leads to Reduced Growth and Enhanced Antifungal Ability. AB - Coniothyrium minitans is an important mycoparasite of Sclerotinia sclerotiorum. In addition, it also produces small amounts of antifungal substances. ZS-1TN1812, an abnormal mutant, was originally screened from a T-DNA insertional library. This mutant showed abnormal growth phenotype and could significantly inhibit the growth of S. sclerotiorum when dual-cultured on a PDA plate. When spraying the filtrate of ZS-1TN1812 on the leaves of rapeseed, S. sclerotiorum infection was significantly inhibited, suggesting that the antifungal substances produced by this mutant were effective on rapeseed leaves. The thermo-tolerant antifungal substances could specifically suppress the growth of S. sclerotiorum, but could not significantly suppress the growth of another fungus, Colletotrichum higginsianum. However, C. higginsianum was more sensitive to proteinous antibiotics than S. sclerotiorum. The T-DNA insertion in ZS-1TN1812 activated the expression of CmSIT1, a gene involved in siderophore-mediated iron transport. It was also determined that mutant ZS-1TN1812 produced hypha with high iron levels. In the wild-type strain ZS-1, CmSIT1 was expressed only when in contact with S. sclerotiorum, and consistent overexpression of CmSIT1 showed similar phenotypes as ZS-1TN1812. Therefore, activated expression of CmSIT1 leads to the enhanced antifungal ability, and CmSIT1 is a potential gene for improving the control ability of C. minitans. PMID- 29176969 TI - Chromobacterium violaceum Pathogenicity: Updates and Insights from Genome Sequencing of Novel Chromobacterium Species. AB - Chromobacterium violaceum is an abundant component of the soil and water microbiota in tropical and subtropical regions around the world. For many years, it was mainly known as a producer of violacein and as a reporter for the discovery of quorum sensing molecules. However, C. violaceum has recently emerged as an important model of an environmental opportunistic pathogen. Its high virulence in human infections and a mouse infection model involves the possession of several predicted virulence traits, including two type III secretion systems (T3SSs). In this article, in addition to providing an update on the new clinical cases of human C. violaceum infections, we will focus on recent advances in understanding the molecular mechanisms regarding C. violaceum pathogenesis. It has been demonstrated that the C. violaceum Cpi-1 T3SS plays a pivotal role in interaction with host cells. It is required for the secretion of effector proteins and is the agonist recognized by the Nod-like receptor CARD domain containing protein 4 (NLRC4) inflammasome from innate immune cells. Pyroptosis and its release of hepatocytes for killing by neutrophils are key events required for the clearance of C. violaceum. Given the prominent role of T3SSs in C. violaceum virulence, we examine their occurrence in the Chromobacterium genus, taking advantage of several draft genome sequences of Chromobacterium species that have recently become available. Our finding that the Cpi-1 T3SS is widespread among Chromobacterium species points toward the pathogenic potential of this genus for humans or to novel roles of the T3SS in the interaction of Chromobacterium species with other organisms. PMID- 29176970 TI - The Mitogen-Activated Protein Kinase CgMK1 Governs Appressorium Formation, Melanin Synthesis, and Plant Infection of Colletotrichum gloeosporioides. AB - The fungus Colletotrichum gloeosporiodes infects plant hosts with a specialized cell called an appressorium, which is melanized and required for plant cell wall penetration. Here, we show that the mitogen-activated protein kinase CgMK1 governs appressorium formation and virulence in the poplar anthracnose fungus C. gloeosporioides. Deletion of CgMK1 impairs aerial hyphal growth and biomass accumulation, and CgMK1 is responsible for the expression of melanin biosynthesis associated genes. CgMK1 deletion mutants are unable to form appressorium and lose the capacity to colonize either wounded or unwounded poplar leaves, leading to loss of virulence. We demonstrate that the exogenous application of cAMP fails to restore defective appressorium formation in the CgMK1 deletion mutants, suggesting that CgMK1 may function downstream or independent of a cAMP-dependent signal for appressorium formation. Moreover, CgMK1 mutants were sensitive to high osmosis, indicating that CgMK1 plays an important role in stress response. We conclude that CgMK1 plays a vital role in regulating appressorium formation, melanin biosynthesis, and virulence in C. gloeosporiodes.

AB - To evaluate the water compartment antibiotic-resistance contamination rates, 11 wells, five streams, and four treatment plants located in the Oltrepo Pavese area were screened for the presence of third generation cephalosporins resistant Gram negative bacteria. Enterobacteriaceae were also characterized for the Extended Spectrum-beta-Lactamases (ESBLs), carbapenemases, and mcr-1 genes presence. From December 2014 to November 2015, 246 water samples were filtered, plated on Plate Count Agar, MacConkey Agar, and MacConkey Agar with cefotaxime. Isolates were species identified using AutoSCAN-4-System and ESBLs, carbapenemases, and colistin resistance determinants were characterized by PCR, sequencing, and microarray. Plasmid conjugative transfer experiments, PCR-based Replicon typing, Pulsed-Field Gel Electrophoresis, Multi-Locus-Sequence-Typing, and in-silico plasmid characterization were performed. A total of 132 enterobacteria isolates grew on MacConkey agar with cefotaxime: 82 (62.1%) were obtained from streams, 41 (31.1%) from treatment plants, and 9 (6.8%) from wells. Thirty out of 132 (22.7%) isolates, mainly belonging to Escherichia coli (n = 15) species, showed a synergic effect with piperacillin-tazobactam. A single ESBL gene of blaCTX-M-type was identified in 19/30 isolates. In further two E. coli strains, a blaCTX-M-1 gene co-existed with a blaSHV-type ESBL determinant. A blaSHV-12 gene was detected in two isolates of E. coli (n = 1) and Klebsiella oxytoca (n = 1), while any ESBL determinant was ascertained in seven Yersinia enterocolitica strains. A blaDHA-type gene was detected in a cefoxitin resistant Y. enterocolitica from a stream. Interestingly, two Klebsiella pneumoniae strains of ST307 and ST258, collected from a well and a wastewater treatment plant, resulted KPC-2, and KPC-3 producers, respectively. Moreover, we report the first detection of mcr-1.2 ST10 E. coli on a conjugative IncX4 plasmid (33.303 bp in size) from a stream of Oltrepo Pavese (Northern Italy). Both ESBLs E. coli and ESBLs/carbapenemase producing K. pneumoniae strains showed clonal heterogeneity by Pulsed-Field Gel Electrophoresis and Multi-Locus-Sequence-Typing. During one-year study and taking in account the whole Gram-negative bacterial population, an average percentage of cefotaxime resistance of 69, 32, and 10.3% has been obtained for the wastewater treatment plants, streams, and wells, respectively. These results, of concern for public health, highlight the need to improve hygienic measures to reduce the load of discharged bacteria with emerging resistance mechanisms. PMID- 29176972 TI - Interleukin-4 Receptor Alpha: From Innate to Adaptive Immunity in Murine Models of Cutaneous Leishmaniasis. AB - The interleukin (IL)-4 receptor alpha (IL-4Ralpha), ubiquitously expressed on both innate and adaptive immune cells, controls the signaling of archetypal type 2 immune regulators; IL-4 and IL-13, which elicit their signaling action by the type 1 IL-4Ralpha/gamma common and/or the type 2 IL-4Ralpha/IL-13Ralpha complexes. Global gene-deficient mouse models targeting IL-4, IL-13, or the IL 4Ralpha chain, followed by the development of conditional mice and generation of important cell-type-specific IL-4Ralpha-deficient mouse models, were indeed critical to gaining in-depth understanding of detrimental T helper (Th) 2 mechanisms in type 1-controlled diseases. A primary example being cutaneous leishmaniasis, which is caused by the protozoan parasite Leishmania major, among others. The disease is characterized by localized self-healing cutaneous lesions and necrosis for which, currently, not a single vaccine has made it to a stage that can be considered effective. The spectrum of human leishmaniasis belongs to the top 10 infectious diseases according to the World Health Organization. As such, 350 million humans are at risk of infection and disease, with an incidence of 1.5-2 million new cases being reported annually. A major aim of our research is to identify correlates of host protection and evasion, which may aid in vaccine design and therapeutic interventions. In this review, we focus on the immune-regulatory role of the IL-4Ralpha chain from innate immune responses to the development of beneficial type 1 and detrimental type 2 adaptive immune responses during cutaneous Leishmania infection. We discuss the cell-specific requirements of the IL-4Ralpha chain on crucial innate immune cells during L. major infection, including, IL-4Ralpha-responsive skin keratinocytes, macrophages, and neutrophils, as well as dendritic cells (DCs). The latter, contributing to one of the paradigm shifts with respect to the role of IL-4 instructing DCs in vivo, to promote Th1 responses against L. major. Finally, we extend these innate responses and mechanisms to control of adaptive immunity and the effect of IL-4Ralpha-responsiveness on T and B lymphocytes orchestrating the development of CD4+ Th1/Th2 and B effector 1/B effector 2 B cells in response to L. major infection in the murine host.

AB - Acute graft-versus-host disease (aGvHD) is a major cause of adverse outcome in hematopoietic stem cell transplantation (HSCT), with a high incidence (20-50%). A novel, non-invasive diagnostic test to predict for prevalence and severity would enable improved prophylaxis and reduce morbidity. Circulatory microRNAs (miRNAs) miR-423, miR-199, miR-93*, and miR-377 have previously been associated with aGvHD in post-HSCT patient plasma, but validation is lacking and their expression within extracellular vesicles (EVs) has not been explored. This study replicated elevated serum expression of miR-423 (p < 0.001), miR-199 (p = 0.04), miR-93* (p < 0.001), and miR-377 (p = 0.03) in aGvHD, using a prognostic cohort of day 14 (D14) post-HSCT patient samples (n = 81). Expression also associated with disease severity. Further analysis at aGvHD diagnosis in an independent cohort (n = 65) confirmed high miR-423 (p = 0.02), miR-199 (p = 0.007), and miR-93* (p = 0.004) expression at disease onset. Investigation of expression patterns during early HSCT sequential timepoints (pre-HSCT to D28) identified elevated miRNAs at D7 post-HSCT in all transplant patients. In a novel investigation of miRNA expression in serum EVs (n = 15), miR-423 (p = 0.09), miR-199 (p = 0.008), and miR-93* (p = 0.001) levels were lower at D14 in patients who later developed aGvHD, and this was replicated for miR-423 (p = 0.02) and miR-199 (p = 0.04) (n = 47). Comparing serum to circulating EVs, at D14 patients remaining aGvHD-free had higher expression of miR-423 (p = 0.03), miR-199 (p = 0.009), and miR-93* (p = 0.002) in the EV fraction. Results verify the capacity for circulating miR-423, miR-199, and miR-93* as diagnostic and prognostic aGvHD biomarkers. The novel finding of their differential expression in EVs suggests a potential role in aGvHD etiology. PMID- 29176974 TI - Inhibition of Epithelial TNF-alpha Receptors by Purified Fruit Bromelain Ameliorates Intestinal Inflammation and Barrier Dysfunction in Colitis. AB - Activation of the TNF-alpha receptor (TNFR) leads to an inflammatory response, and anti-TNF therapy has been administered to reduce inflammation symptoms and heal mucosal ulcers in inflammatory bowel disease (IBD). Bromelain, a complex natural mixture of proteolytic enzymes, has been shown to exert anti-inflammatory effects. This study aimed to investigate the effect of purified fruit bromelain (PFB)-induced inhibition of epithelial TNFR in a rat colitis model. Colitis was established by intracolonic administration of 2, 4, 6-trinitrobenzene sulfonic acid. Expression of TNFR1 and TNFR2 was measured by quantitative RT-PCR and western blotting. The effect of PFB on colitis was evaluated by examining the inflammatory response and intestinal epithelial barrier function. Our results showed that both TNFR1 and TNFR2 expression were significantly increased in a colitis model, and the increase was significantly reversed by PFB. Colitis symptoms, including infiltration of inflammatory cells, cytokine profiles, epithelial cell apoptosis, and epithelial tight junction barrier dysfunction were significantly ameliorated by PFB. Compared with fruit bromelain and stem bromelain complex, the inhibition of TNFR2 induced by PFB was stronger than that exhibited on TNFR1. These results indicate that PFB showed a stronger selective inhibitory effect on TNFR2 than TNFR1. In other words, purification of fruit bromelain increases its selectivity on TNFR2 inhibition. High expression of epithelial TNFRs in colitis was significantly counteracted by PFB, and PFB induced TNFR inhibition ameliorated colitis symptoms. These results supply novel insights into potential IBD treatment by PFB. PMID- 29176976 TI - Engineering Specificity and Function of Therapeutic Regulatory T Cells. AB - Adoptive therapy with polyclonal regulatory T cells (Tregs) has shown efficacy in suppressing detrimental immune responses in experimental models of autoimmunity and transplantation. The lack of specificity is a potential limitation of Treg therapy, as studies in mice have demonstrated that specificity can enhance the therapeutic potency of Treg. We will discuss that vectors encoding T cell receptors or chimeric antigen receptors provide an efficient gene-transfer platform to reliably produce Tregs of defined antigen specificity, thus overcoming the considerable difficulties of isolating low-frequency, antigen specific cells that may be present in the natural Treg repertoire. The recent observations that Tregs can polarize into distinct lineages similar to the Th1, Th2, and Th17 subsets described for conventional T helper cells raise the possibility that Th1-, Th2-, and Th17-driven pathology may require matching Treg subsets for optimal therapeutic efficacy. In the future, genetic engineering may serve not only to enforce FoxP3 expression and a stable Treg phenotype but it may also enable the expression of particular transcription factors that drive differentiation into defined Treg subsets. Together, established and recently developed gene transfer and editing tools provide exciting opportunities to produce tailor-made antigen-specific Treg products with defined functional activities. PMID- 29176975 TI - Targeting Cannabinoid Signaling in the Immune System: "High"-ly Exciting Questions, Possibilities, and Challenges. AB - It is well known that certain active ingredients of the plants of Cannabis genus, i.e., the "phytocannabinoids" [pCBs; e.g., (-)-trans-Delta9-tetrahydrocannabinol (THC), (-)-cannabidiol, etc.] can influence a wide array of biological processes, and the human body is able to produce endogenous analogs of these substances ["endocannabinoids" (eCB), e.g., arachidonoylethanolamine (anandamide, AEA), 2 arachidonoylglycerol (2-AG), etc.]. These ligands, together with multiple receptors (e.g., CB1 and CB2 cannabinoid receptors, etc.), and a complex enzyme and transporter apparatus involved in the synthesis and degradation of the ligands constitute the endocannabinoid system (ECS), a recently emerging regulator of several physiological processes. The ECS is widely expressed in the human body, including several members of the innate and adaptive immune system, where eCBs, as well as several pCBs were shown to deeply influence immune functions thereby regulating inflammation, autoimmunity, antitumor, as well as antipathogen immune responses, etc. Based on this knowledge, many in vitro and in vivo studies aimed at exploiting the putative therapeutic potential of cannabinoid signaling in inflammation-accompanied diseases (e.g., multiple sclerosis) or in organ transplantation, and to dissect the complex immunological effects of medical and "recreational" marijuana consumption. Thus, the objective of the current article is (i) to summarize the most recent findings of the field; (ii) to highlight the putative therapeutic potential of targeting cannabinoid signaling; (iii) to identify open questions and key challenges; and (iv) to suggest promising future directions for cannabinoid-based drug development. PMID- 29176978 TI - Requirement of Gamma-Carboxyglutamic Acid Modification and Phosphatidylserine Binding for the Activation of Tyro3, Axl, and Mertk Receptors by Growth Arrest Specific 6. AB - The Tyro3, Axl, and Mertk (TAM) receptors are homologous type I receptor tyrosine kinases that have critical functions in the clearance of apoptotic cells in multicellular organisms. TAMs are activated by their endogenous ligands, growth arrest-specific 6 (Gas6), and protein S (Pros1), that function as bridging molecules between externalized phosphatidylserine (PS) on apoptotic cells and the TAM ectodomains. However, the molecular mechanisms by which Gas6/Pros1 promote TAM activation remains elusive. Using TAM/IFNgammaR1 reporter cell lines to monitor functional TAM activity, we found that Gas6 activity was exquisitely dependent on vitamin K-mediated gamma-carboxylation, whereby replacing vitamin K with anticoagulant warfarin, or by substituting glutamic acid residues involved in PS binding, completely abrogated Gas6 activity as a TAM ligand. Furthermore, using domain and point mutagenesis, Gas6 activity also required both an intact Gla domain and intact EGF-like domains, suggesting these domains function cooperatively in order to achieve TAM activation. Despite the requirement of gamma-carboxylation and the functional Gla domain, non-gamma-carboxylated Gas6 and Gla deletion/EGF-like domain deletion mutants still retained their ability to bind TAMs and acted as blocking decoy ligands. Finally, we found that distinct sources of PS-positive cells/vesicles (including apoptotic cells, calcium-induced stressed cells, and exosomes) bound Gas6 and acted as cell-derived or exosome derived ligands to activate TAMs. Taken together, our findings indicate that PS is indispensable for TAM activation by Gas6, and by inference, provides new perspectives on how PS, regulates TAM receptors and efferocytosis. PMID- 29176979 TI - US6 Gene Deletion in Herpes Simplex Virus Type 2 Enhances Dendritic Cell Function and T Cell Activation. AB - Herpes simplex virus (HSV) type 1 (HSV-1) and type 2 (HSV-2) produce lifelong infections that are associated with frequent asymptomatic or clinically apparent reactivation. Importantly, HSV express multiple virulence factors that negatively modulate innate and adaptive immune components. Notably, HSV interfere with dendritic cell (DC) viability and function, likely hindering the capacity of the host to mount effective immunity against these viruses. Recently, an HSV-2 virus that was deleted in glycoprotein D was engineered (designated DeltagD-2). The virus is propagated on a complementing cell line that expresses HSV-1 gD, which permits a single round of viral replication. DeltagD-2 is safe, immunogenic, and provided complete protection against vaginal or skin challenges with HSV-1 and HSV-2 in murine models. Here, we sought to assess the interaction of DeltagD-2 with DCs and found that, in contrast to wild-type (WT) virus which induces DC apoptosis, DeltagD-2 promoted their migration and capacity to activate naive CD8+ and CD4+ T cells in vitro and in vivo. Furthermore, DCs exposed to the WT and DeltagD-2 virus experienced different unfolded protein responses. Mice primed with DCs infected with DeltagD-2 in vitro displayed significantly reduced infection and pathology after genital challenge with virulent HSV-2 compared to non-primed mice, suggesting that DCs play a role in the immune response to the vaccine strain. PMID- 29176980 TI - iRAGu: A Novel Inducible and Reversible Mouse Model for Ubiquitous Recombinase Activity. AB - Developing lymphocytes express the recombination activating genes (RAGs) 1 and 2 products that form a site specific recombinase complex (RAG), introducing double strand DNA breaks (DSBs) at recombination signal sequences (RSSs) flanking the V, D, and J gene segments in the antigen receptor loci. The subsequent steps in the reaction consist in the ligation of DSBs by ubiquitous enzymes of the non homologous end joining DNA repair pathway. This mutagenesis process is responsible for the generation of the very large clonal diversity of T and B lymphocytes, itself allowing the recognition of a virtually open-ended antigenic universe. Sequences resembling RSS are found at high frequency all over the genome, and involved in RAG mediated illegitimate recombination and translocations. Hence, natural and induced ectopic activity of RAG is a threat to the genome only recently underscored. Here, we report and characterize a novel mouse transgenic system for which ubiquitous expression of the recombinase is inducible. In this system, the RAG1 protein is constitutively expressed and functional, while the RAG2 protein, coupled to the estrogen receptor, becomes functionally active upon 4-hydroxytamoxifen (TAM) administration. We describe two transgenic lines. The first one, when introgressed into an endogenous Rag2-/- genetic background is faithfully recapitulating lymphocyte development, repertoire dynamics and cryptic rearrangements, in a TAM-dependent manner. In this model, deprivation of TAM is followed by lymphocyte development arrest, evidencing the reversibility of the system. The second transgenic line is leaky, as the transgenes promote lymphocyte differentiation in absence of TAM treatment. Upon TAM-induction defects in lymphocytes composition and global health reveals the deleterious effect of uncontrolled RAG activity. Overall, this novel transgenic model provides a tool where RAG activity can be specifically manipulated to assess the dynamics of lymphocyte differentiation and the challenges imposed by the recombinase on the vertebrate genome. PMID- 29176977 TI - Molecular Mechanisms Modulating the Phenotype of Macrophages and Microglia. AB - Macrophages and microglia play crucial roles during central nervous system development, homeostasis and acute events such as infection or injury. The diverse functions of tissue macrophages and microglia are mirrored by equally diverse phenotypes. A model of inflammatory/M1 versus a resolution phase/M2 macrophages has been widely used. However, the complexity of macrophage function can only be achieved by the existence of varied, plastic and tridimensional macrophage phenotypes. Understanding how tissue macrophages integrate environmental signals via molecular programs to define pathogen/injury inflammatory responses provides an opportunity to better understand the multilayered nature of macrophages, as well as target and modulate cellular programs to control excessive inflammation. This is particularly important in MS and other neuroinflammatory diseases, where chronic inflammatory macrophage and microglial responses may contribute to pathology. Here, we perform a comprehensive review of our current understanding of how molecular pathways modulate tissue macrophage phenotype, covering both classic pathways and the emerging role of microRNAs, receptor-tyrosine kinases and metabolism in macrophage phenotype. In addition, we discuss pathway parallels in microglia, novel markers helpful in the identification of peripheral macrophages versus microglia and markers linked to their phenotype. PMID- 29176981 TI - Bifidobacterium infantis Potentially Alleviates Shrimp Tropomyosin-Induced Allergy by Tolerogenic Dendritic Cell-Dependent Induction of Regulatory T Cells and Alterations in Gut Microbiota. AB - Shellfish is one of the major allergen sources worldwide, and tropomyosin (Tm) is the predominant allergic protein in shellfish. Probiotics has been appreciated for its beneficial effects on the host, including anti-allergic and anti inflammatory effects, although the underlying mechanisms were not fully understood. In this study, oral administration of probiotic strain Bifidobacterium infantis 14.518 (Binf) effectively suppressed Tm-induced allergic response in a mouse model by both preventive and therapeutic strategies. Further results showed that Binf stimulated dendritic cells (DCs) maturation and CD103+ tolerogenic DCs accumulation in gut-associated lymphoid tissue, which subsequently induced regulatory T cells differentiation for suppressing Th2 biased response. We also found that Binf regulates the alterations of gut microbiota composition. Specifically, the increase of Dorea and decrease of Ralstonia is highly correlated with Th2/Treg ratio and may contribute to alleviating Tm-induced allergic responses. Our findings provide molecular insight into the application of Binf in alleviating food allergy and even gut immune homeostasis. PMID- 29176982 TI - Suppressor of Cytokine Signaling 3 in Macrophages Prevents Exacerbated Interleukin-6-Dependent Arginase-1 Activity and Early Permissiveness to Experimental Tuberculosis. AB - Suppressor of cytokine signaling 3 (SOCS3) is a feedback inhibitor of interleukin (IL)-6 signaling in macrophages. In the absence of this molecule, macrophages become extremely prone to an IL-6-dependent expression of arginase-1 (Arg1) and nitric oxide synthase (NOS)2, the prototype markers for alternative or classical macrophage activation, respectively. Because both enzymes are antipodean macrophage effector molecules in Mycobacterium tuberculosis (Mtb) infection, we assessed the relevance of SOCS3 for macrophage activation during experimental tuberculosis using macrophage-specific SOCS3-deficient (LysMcreSOCS3loxP/loxP) mice. Aerosol infection of LysMcreSOCS3loxP/loxP mice resulted in remarkably higher bacterial loads in infected lungs and exacerbated pulmonary inflammation. This increased susceptibility to Mtb infection was accompanied by enhanced levels of both classical and alternative macrophage activation. However, high Arg1 expression preceded the increased induction of NOS2 and at early time points of infection mycobacteria were mostly found in cells positive for Arg1. This sequential activation of Arg1 and NOS2 expression in LysMcreSOCS3loxP/loxP mice appears to favor the initial replication of Mtb particularly in Arg1-positive cells. Neutralization of IL-6 in Mtb-infected LysMcreSOCS3loxP/loxP mice reduced arginase activity and restored control of mycobacterial replication in LysMcreSOCS3loxP/loxP mice. Our data reveal an unexpected role of SOCS3 during experimental TB: macrophage SOCS3 restrains early expression of Arg1 and helps limit Mtb replication in resident lung macrophages, thereby limiting the growth of mycobacteria. Together, SOCS3 keeps IL-6-dependent divergent macrophage responses such as Nos2 and Arg1 expression under control and safeguard protective macrophage effector mechanisms. PMID- 29176983 TI - Mucosal-Associated Invariant T Cells: New Insights into Antigen Recognition and Activation. AB - Mucosal-associated invariant T (MAIT) cells, a novel subpopulation of innate-like T cells that express an invariant T cell receptor (TCR)alpha chain and a diverse TCRbeta chain, can recognize a distinct set of small molecules, vitamin B metabolites, derived from some bacteria, fungi but not viruses, in the context of an evolutionarily conserved major histocompatibility complex-related molecule 1 (MR1). This implies that MAIT cells may play unique and important roles in host immunity. Although viral antigens are not recognized by this limited TCR repertoire, MAIT cells are known to be activated in a TCR-independent mechanism during some viral infections, such as hepatitis C virus and influenza virus. In this article, we will review recent works in MAIT cell antigen recognition, activation and the role MAIT cells may play in the process of bacterial and viral infections and pathogenesis of non-infectious diseases. PMID- 29176984 TI - The Dynamic Interplay between HIV-1, SAMHD1, and the Innate Antiviral Response. AB - The innate immune response constitutes the first cellular line of defense against initial HIV-1 infection. Immune cells sense invading virus and trigger signaling cascades that induce antiviral defenses to control or eliminate infection. Professional antigen-presenting cells located in mucosal tissues, including dendritic cells and macrophages, are critical for recognizing HIV-1 at the site of initial exposure. These cells are less permissive to HIV-1 infection compared to activated CD4+ T-cells, which is mainly due to host restriction factors that serve an immediate role in controlling the establishment or spread of viral infection. However, HIV-1 can exploit innate immune cells and their cellular factors to avoid detection and clearance by the host immune system. Sterile alpha motif and HD-domain containing protein 1 (SAMHD1) is the mammalian deoxynucleoside triphosphate triphosphohydrolase responsible for regulating intracellular dNTP pools and restricting the replication of HIV-1 in non-dividing myeloid cells and quiescent CD4+ T-cells. Here, we review and analyze the latest literature on the antiviral function of SAMHD1, including the mechanism of HIV-1 restriction and the ability of SAMHD1 to regulate the innate immune response to viral infection. We also provide an overview of the dynamic interplay between HIV 1, SAMHD1, and the cell-intrinsic antiviral response to elucidate how SAMHD1 modulates HIV-1 infection in non-dividing immune cells. A more complete understanding of SAMHD1's role in the innate immune response to HIV-1 infection may help develop stratagems to enhance its antiviral effects and to more efficiently block HIV-1 replication and avoid the pathogenic result of viral infection. PMID- 29176985 TI - Mucosal IgA Responses: Damaged in Established HIV Infection-Yet, Effective Weapon against HIV Transmission. AB - HIV infection not only destroys CD4+ T cells but also inflicts serious damage to the B-cell compartment, such as lymphadenopathy, destruction of normal B-cell follicle architecture, polyclonal hypergammaglobulinemia, increased apoptosis of B cells, and irreversible loss of memory B-cell responses with advanced HIV disease. Subepithelial B cells and plasma cells are also affected, which results in loss of mucosal IgG and IgA antibodies. This leaves the mucosal barrier vulnerable to bacterial translocation. The ensuing immune activation in mucosal tissues adds fuel to the fire of local HIV replication. We postulate that compromised mucosal antibody defenses also facilitate superinfection of HIV positive individuals with new HIV strains. This in turn sets the stage for the generation of circulating recombinant forms of HIV. What can the mucosal B-cell compartment contribute to protect a healthy, uninfected host against mucosal HIV transmission? Here, we discuss proof-of-principle studies we have performed using passive mucosal immunization, i.e., topical administration of preformed anti-HIV monoclonal antibodies (mAbs) as IgG1, dimeric IgA1 (dIgA1), and dIgA2 isotypes, alone or in combination. Our data indicate that mucosally applied anti-HIV envelope mAbs can provide potent protection against mucosal transmission of simian-human immunodeficiency virus. Our review also discusses the induction of mucosal antibody defenses by active vaccination and potential strategies to interrupt the vicious cycle of bacterial translocation, immune activation, and stimulation of HIV replication in individuals with damaged mucosal barriers. PMID- 29176987 TI - Radiocarbon Dating of an Olive Tree Cross-Section: New Insights on Growth Patterns and Implications for Age Estimation of Olive Trees. AB - The age of living massive olive trees is often assumed to be between hundreds and even thousands of years. These estimations are usually based on the girth of the trunk and an extrapolation based on a theoretical annual growth rate. It is difficult to objectively verify these claims, as a monumental tree may not be cut down for analysis of its cross-section. In addition, the inner and oldest part of the trunk in olive trees usually rots, precluding the possibility of carting out radiocarbon analysis of material from the first years of life of the tree. In this work we present a cross-section of an olive tree, previously estimated to be hundreds of years old, which was cut down post-mortem in 2013. The cross-section was radiocarbon dated at numerous points following the natural growth pattern, which was made possible to observe by viewing the entire cross-section. Annual growth rate values were calculated and compared between different radii. The cross-section also revealed a nearly independent segment of growth, which would clearly offset any estimations based solely on girth calculations. Multiple piths were identified, indicating the beginning of branching within the trunk. Different radii were found to have comparable growth rates, resulting in similar estimates dating the piths to the 19th century. The estimated age of the piths represent a terminus ante quem for the age of the tree, as these are piths of separate branches. However, the tree is likely not many years older than the dated piths, and certainly not centuries older. The oldest radiocarbon-datable material in this cross-section was less than 200 years old, which is in agreement with most other radiocarbon dates of internal wood from living olive trees, rarely older than 300 years. PMID- 29176986 TI - Dissecting the Variations of Ripening Progression and Flavonoid Metabolism in Grape Berries Grown under Double Cropping System. AB - A double cropping system has been commercially adopted in southern China, where there is abundant sunshine and heat resources. In this viticulture system, the first growing season normally starts as a summer cropping cycle; then, the vine is pruned and forced, resulting in a second crop in winter. Due to climate differences between the summer and winter growing seasons, grape ripening progression and flavonoid metabolism vary greatly. Here, the metabolites and transcriptome of flavonoid pathways were analyzed in grapes grown under two growing seasons at different stages. Notably, the winter cropping cycle strongly increased flavonoid levels by several times in comparison to summer grapes, while the summer season took a major toll on anthocyanin and flavonol accumulation, since the winter cropping greatly triggered the expression of upstream genes in the flavonoid pathway in a coordinated expression pattern. Moreover, the ratio of VviF3'5'Hs (flavonoid 3'5'-hydroxylase) to VviF3'Hs (flavonoid 3'-hydroxylase) transcript levels correlated remarkably well with the ratio of 3'5'-substituted to 3'-substituted flavonoids, which was presumed to control the flux of intermediates into different flavonoid branches. On the other hand, the phenological phase also varied greatly in the two crops. Compared to summer cropping, winter growing season accelerated the duration from budburst to veraison, therefore advancing the onset of ripening, but also prolonging the duration of ripening progression due to the purposes to harvest high-quality grapes. The differential expression pattern of hormone-related genes between the two cropping cycles might explain this phenomenon.

AB - Bamboo species-the only herbaceous trees-have unique structural and physiological characteristics that differ from those of other tree taxa. However, the role of night-time water use in bamboo is poorly understood and has rarely been investigated. We studied the day- and night-time sap flow response to culm age and rhizome structure in three age levels (juvenile, mature, and senescent) of Phyllostachys pubescens growing in the Nankun Mountain Natural Reserve, South China. We found that sap flow density and whole-tree hydraulic conductance decreased with culm age. After cutting of rhizome, the day-time sap flow and night-time water recharge decreased obviously. In addition, night-time water recharge accounted for the largest proportion (up to 30%) of total daily transpiration in normal senescent bamboos. Therefore, our study indicates that the connected rhizome system and night-time water recharge played a significant role in water compensation during the day and at night in bamboos. Night-time water recharge is especially critical to senescent bamboos, given their weaker transpiration due to the lower whole-tree hydraulic conductance, and consequently, they are more dependent on night-time water recharge for fulfilling their whole-day water consumption needs. PMID- 29176988 TI - Genome-Wide Association Mapping of Flowering and Ripening Periods in Apple. AB - Deciphering the genetic control of flowering and ripening periods in apple is essential for breeding cultivars adapted to their growing environments. We implemented a large Genome-Wide Association Study (GWAS) at the European level using an association panel of 1,168 different apple genotypes distributed over six locations and phenotyped for these phenological traits. The panel was genotyped at a high-density of SNPs using the Axiom(r)Apple 480 K SNP array. We ran GWAS with a multi-locus mixed model (MLMM), which handles the putatively confounding effect of significant SNPs elsewhere on the genome. Genomic regions were further investigated to reveal candidate genes responsible for the phenotypic variation. At the whole population level, GWAS retained two SNPs as cofactors on chromosome 9 for flowering period, and six for ripening period (four on chromosome 3, one on chromosome 10 and one on chromosome 16) which, together accounted for 8.9 and 17.2% of the phenotypic variance, respectively. For both traits, SNPs in weak linkage disequilibrium were detected nearby, thus suggesting the existence of allelic heterogeneity. The geographic origins and relationships of apple cultivars accounted for large parts of the phenotypic variation. Variation in genotypic frequency of the SNPs associated with the two traits was connected to the geographic origin of the genotypes (grouped as North+East, West and South Europe), and indicated differential selection in different growing environments. Genes encoding transcription factors containing either NAC or MADS domains were identified as major candidates within the small confidence intervals computed for the associated genomic regions. A strong microsynteny between apple and peach was revealed in all the four confidence interval regions. This study shows how association genetics can unravel the genetic control of important horticultural traits in apple, as well as reduce the confidence intervals of the associated regions identified by linkage mapping approaches. Our findings can be used for the improvement of apple through marker-assisted breeding strategies that take advantage of the accumulating additive effects of the identified SNPs. PMID- 29176990 TI - Uranium Leaching from Contaminated Soil Utilizing Rhamnolipid, EDTA, and Citric Acid. AB - Biosurfactants have recently gained attention as "green" agents that can be used to enhance the remediation of heavy metals and some organic matter in contaminated soils. The overall objective of this paper was to investigate rhamnolipid, a microbial produced biosurfactant, and its ability to leach uranium present in contaminated soil from an abandoned mine site. Soil samples were collected from two locations in northern Arizona: Cameron (site of open pit mining) and Leupp (control-no mining). The approach taken was to first determine the total uranium content in each soil using a hydrofluoric acid digestion, then comparing the amount of metal removed by rhamnolipid to other chelating agents EDTA and citric acid, and finally determining the amount of soluble metal in the soil matrix using a sequential extraction. Results suggested a complex system for metal removal from soil utilizing rhamnolipid. It was determined that rhamnolipid at a concentration of 150 MUM was as effective as EDTA but not as effective as citric acid for the removal of soluble uranium. However, the rhamnolipid was only slightly better at removing uranium from the mining soil compared to a purified water control. Overall, this study demonstrated that rhamnolipid ability to remove uranium from contaminated soil is comparable to EDTA and to a lesser extent citric acid, but, for the soils investigated, it is not significantly better than a simple water wash. PMID- 29176992 TI - Immunosenescence in persons with spinal cord injury in relation to urinary tract infections -a cross-sectional study. AB - Background: Individuals with a spinal cord injury (SCI), despite specialized rehabilitation and good health care, have a reduced life expectancy. Infectious diseases, such as pneumonias, infected pressure sores and urinary tract infections (UTI) have been identified as the leading causes of mortality. We hypothesise that a premature onset of immune frailty occurs in SCI, possibly caused also by recurrent urinary tract infections.A cross sectional study was performed comparing blood and urine samples between able bodied controls (n = 84) and persons with spinal cord injury (n = 85). The results were grouped according to age (below and above 60 years). Assessed were the abundancies of immune cells, the concentration of soluble biomarkers, the in vitro functioning of lymphocytes as well as phenotypic exhaustion of T-cells in blood and urine. Further, the leucocyte telomere length and the cytomegalovirus (CMV) serological status were compared between the groups. Results: We observed in people with SCI lower proportions of naive T-cells, more memory T-cells, reduced T-cell proliferation and higher CMV prevalence compared to age-matched controls. SCI participants older than 60 years had a higher prevalence of UTI compared with SCI persons younger than 60 years. Conclusion: The immune system of people with SCI shows traits of an increased immunological strain and a premature onset of immune frailty. The role of UTI in the onset of immune frailty remains to be elucidated as we did not see significantly higher abundancies of circulating UTI-bacteria specific T-cell clones in persons with SCI. We assume that any impact of UTI on the immune system might be compartmentalized and locally restricted to the urinary tract. PMID- 29176991 TI - Asthma biomarkers in the age of biologics. AB - The heterogeneous nature of asthma has been understood for decades, but the precise categorization of asthma has taken on new clinical importance in the era of specific biologic therapy. The simple categories of allergic and non-allergic asthma have given way to more precise phenotypes that hint at underlying biologic mechanisms of variable airflow limitation and airways inflammation. Understanding these mechanisms is of particular importance for the approximately 10% of patients with severe asthma. Biomarkers that aid in phenotyping allow physicians to "personalize" treatment with targeted biologic agents. Unfortunately, testing for these biomarkers is not routine in patients whose asthma is refractory to standard therapy. Scientific advances in the recognition of sensitive and specific biomarkers are steadily outpacing the clinical availability of reliable and non-invasive assessment methods designed for the prompt and specific diagnosis, classification, treatment, and monitoring of severe asthma patients. This article provides a practical overview of current biomarkers and testing methods for prompt, effective management of patients with severe asthma that is refractory to standard therapy. PMID- 29176993 TI - An excess dietary vitamin E concentration does not influence Nrf2 signaling in the liver of rats fed either soybean oil or salmon oil. AB - Background: Reactive oxygen species (ROS) are known to stimulate the activation of nuclear factor-erythroid 2-related factor-2 (Nrf2), the key regulator of the antioxidant and cytoprotective defense system in the body. The hypothesis underlying this study was that high dietary concentrations of vitamin E suppress Nrf2 activation, and thus could weaken the body's antioxidative and cytoprotective capacity. As the effect of vitamin E on Nrf2 pathway might be influenced by concentrations of fatty acids susceptible to oxidation in the diet, we used also diets containing either soybean oil as a reference oil or salmon oil as a source of oil rich in n-3 polyunsatuated fatty acids. Methods: Seventy-two rats were divided into 6 groups of rats which received diets with either 25, 250 or 2500 mg vitamin E/kg, with either soybean oil or salmon oil as dietary fat sources according to a bi-factorial experimental design. Electron spin resonance spectroscopy was used to determine ROS production in the liver. qPCR analysis and western blot were performed to examine the expression of Nrf2 target genes in the liver of rats. Results: Rats fed the salmon oil diet with 25 mg vitamin E/kg showed a higher production of ROS in the liver than the 5 other groups of rats which did not differ in ROS production. Relative mRNA concentrations of NFE2L2 (encoding Nrf2), KEAP1 and various Nrf2 target genes, protein concentrations of glutathione peroxidase (GPX), heme oxygenase 1 (HO-1), NAD(P)H quinone dehydrogenase 1 (NQO1) and activities of the antioxidant enzymes GPX, superoxide dismutase and catalase were not influenced by the dietary vitamin E concentration. The dietary fat had also less effect on Nrf2 target genes and no effect on protein concentrations of GPX, HO-1, NQO1 and activities of antioxidant enzymes. Dietary vitamin E concentration and type of fat moreover had less effect on mRNA concentrations of genes and concentrations of proteins involved in the unfolded protein response, a pathway which is closely linked with activation of Nrf2. Conclusion: We conclude that excess dietary concentrations of vitamin E do not suppress Nrf2 signaling, and thus do not weaken the endogenous antioxidant and cytoprotective capacity in the liver of rats. PMID- 29176994 TI - Antiobesity potential of Piperonal: promising modulation of body composition, lipid profiles and obesogenic marker expression in HFD-induced obese rats. AB - Background: Black pepper or Piper nigrum is a well-known spice, rich in a variety of bioactive compounds, and widely used in many cuisines across the world. In the Indian traditional systems of medicine, it is used to treat gastric and respiratory ailments. The purpose of this investigation is to study the antihyperlipidemic and antiobesity effects of piperonal in high-fat diet (HFD) induced obese rats. Methods: Piperonal, an active constituent of Piper nigrum seeds, was isolated and confirmed by HPLC, 1H and 13C NMR spectroscopy. Male SD rats were fed on HFD for 22 weeks; Piperonal was supplemented from the 16th week as mentioned in the experimental design. Changes in body weight and body composition were measured by TOBEC, bone mineral composition and density were measured by DXA, and adipose tissue distribution was measured by 7 T-MRI. Plasma levels of glucose, insulin, insulin resistance and lipid profiles of plasma, liver and kidney, adipocyte hormones and liver antioxidants were evaluated using standard kit methods. Expression levels of adipogenic and lipogenic genes, such as PPAR-gamma, FAS, Fab-4, UCP-2, SREBP-1c, ACC, HMG-COA and TNF-alpha were measured by RT-PCR. Histopathological examination of adipose and liver tissues was also carried out in experimental rats. Results: HFD substantially induced body weight, fat%, adipocyte size, circulatory and tissue lipid profiles. It elevated the plasma levels of insulin, insulin resistance and leptin but decreased the levels of adiponectin, BMC and BMD. Increased expression of PPAR gamma, FAS, Fab-4, UCP-2, SREBP-1c, ACC, and TNF-alpha was noticed in HFD-fed rats. However, supplementation of piperonal (20, 30 and 40 mg/kg b.wt) for 42 days considerably and dose-dependently attenuated the HFD-induced alterations, with the maximum therapeutic activity being noticed at 40 mg/kg b.wt. Conclusions: Piperonal significantly attenuated HFD-induced body weight and biochemical changes through modulation of key lipid metabolizing and obesogenic genes. Our findings demonstrate the efficacy of piperonal as a potent antiobesity agent, provide scientific evidence for its traditional use and suggest the possible mechanism of action. PMID- 29176995 TI - Depression is related to dietary diversity score in women: a cross-sectional study from a developing country. AB - Background: Substantial evidence provides support for the role of diet in the prevention and control of mental disorders. However, since there is no study regarding the relationship between dietary diversity and stress or depression, we aimed to determine the relationship between the dietary diversity score (DDS) and stress and depression in women. Methods: This descriptive-analytical cross sectional study was performed on 360 women aged 20-49 years attending health centers in the south of Tehran. The dietary intake and score of depression, anxiety, and stress were measured using a 24-h dietary recall and the 42-item depression, anxiety, stress scales questionnaire, respectively. The DDS was calculated based on the FAO 2013 guidelines. Data were analyzed using Chi-square, analysis of variance, Spearman correlation coefficient, and multivariable logistic regression tests. Results: In total, 31.4 and 25.8% of the subjects suffered from depression and stress, respectively. After adjusting for confounders, a one-unit increase in DDS was associated with a 39% reduction in the risk of severe depression. The DDS was not significantly associated with mild or moderate depression, and no significant relationship was observed between the DDS and stress. Conclusions: The DDS could be inversely associated with depression in women. Since we observed no significant relationship between stress and DDS, further studies are needed in this regard. PMID- 29176996 TI - Mental, neurologic, and substance use (MNS) disorders among street homeless people in Ethiopia. AB - Background: About 25-60% of the homeless population is reported to have some form of mental disorder. To our knowledge, there are no studies aimed at the screening, diagnosis, treatment, care, rehabilitation, and support of homeless people with mental, neurologic, and substance use (MNS) disorders in general in Ethiopia. This is the first study of its kind in Africa which was aimed at screening, diagnosis, care, treatment, rehabilitation, and support of homeless individuals with possible MNS disorder. Methods: Community-based survey was conducted from January to March 2015. Homeless people who had overt and observable psychopathology and positive for screening instruments (SRQ20, ASSIST, and PSQ) were involved in the survey and further assessed for possible diagnosis by structured clinical interview for DSM-IV diagnoses and international diagnostic criteria for seizure disorders for possible involvement in care, treatment, rehabilitation services, support, and training. The Statistical Program for Social Science (SPSS version 20) was used for data entry, clearance, and analyses. Results: A total of 456 homeless people were involved in the survey. Majority of the participants were male (n = 402; 88.16%). Most of the homeless participants had migrated into Addis Ababa from elsewhere in Ethiopia and Eritrea (62.50%). Mental, neurologic, and substance use disorders resulted to be common problems in the study participants (92.11%; n = 420). Most of the participants with mental, neurologic, and substance use disorders (85.29%; n = 354) had psychotic disorders. Most of those with psychosis had schizophrenia (77.40%; n = 274). Almost all of the participants had a history of substance use (93.20%; n = 425) and about one in ten individuals had substance use disorders (10.54%; n = 48). Most of the participants with substance use disorder had comorbid other mental and neurologic disorders (83.33%; n = 40). Conclusion and recommendation: Mental, neurologic, and substance use disorders are common (92.11%) among street homeless people in Ethiopia. The development of centers for care, treatment, rehabilitation, and support of homeless people with mental, neurologic, and substance use disorders is warranted. In addition, it is necessary to improve the accessibility of mental health services and promote better integration between mental and primary health care services, as a means to offer a better general care and to possibly prevent homelessness among mentally ill. PMID- 29176997 TI - Association between an angiotensin-converting enzyme gene polymorphism and Alzheimer's disease in a Tunisian population. AB - Background: The angiotensin-converting enzyme gene (ACE) insertion/deletion (I/D or indel) polymorphism has long been linked to Alzheimer's disease (AD), but the interpretation of established data remains controversial. The aim of this study was to determine whether the angiotensin-converting enzyme is associated with the risk of Alzheimer's disease in Tunisian patients. Methods: We analyzed the genotype and allele frequency distribution of the ACE I/D gene polymorphism in 60 Tunisian AD patients and 120 healthy controls. Results: There is a significantly increased risk of AD in carriers of the D/D genotype (51.67% in patients vs. 31.67% in controls; p = .008, OR = 2.32). The D allele was also more frequently found in patients compared with controls (71.67% vs. 56.25%; p = .003, OR = 2.0). Moreover, as assessed by the Mini-Mental State Examination, patient D/D carriers were more frequently found to score in the severe category of dementia (65%) as compared to the moderate category (32%) or mild category (3%). Conclusions: The D/D genotype and D allele of the ACE I/D polymorphism were associated with an increased risk in the development of AD in a Tunisian population. Furthermore, at the time of patient evaluation (average age 75 years), patients suffering with severe dementia were found predominantly in D/D carriers and, conversely, the D/D genotype and D allele were more frequently found in AD patients with severe dementia. These preliminary exploratory results should be confirmed in larger studies and further work is required to explore and interpret possible alternative findings in diverse populations. PMID- 29176998 TI - A novel 3D imaging system for strawberry phenotyping. AB - Background: Accurate and quantitative phenotypic data in plant breeding programmes is vital in breeding to assess the performance of genotypes and to make selections. Traditional strawberry phenotyping relies on the human eye to assess most external fruit quality attributes, which is time-consuming and subjective. 3D imaging is a promising high-throughput technique that allows multiple external fruit quality attributes to be measured simultaneously. Results: A low cost multi-view stereo (MVS) imaging system was developed, which captured data from 360 degrees around a target strawberry fruit. A 3D point cloud of the sample was derived and analysed with custom-developed software to estimate berry height, length, width, volume, calyx size, colour and achene number. Analysis of these traits in 100 fruits showed good concordance with manual assessment methods. Conclusion: This study demonstrates the feasibility of an MVS based 3D imaging system for the rapid and quantitative phenotyping of seven agronomically important external strawberry traits. With further improvement, this method could be applied in strawberry breeding programmes as a cost effective phenotyping technique. PMID- 29176999 TI - A robot-assisted imaging pipeline for tracking the growths of maize ear and silks in a high-throughput phenotyping platform. AB - Background: In maize, silks are hundreds of filaments that simultaneously emerge from the ear for collecting pollen over a period of 1-7 days, which largely determines grain number especially under water deficit. Silk growth is a major trait for drought tolerance in maize, but its phenotyping is difficult at throughputs needed for genetic analyses. Results: We have developed a reproducible pipeline that follows ear and silk growths every day for hundreds of plants, based on an ear detection algorithm that drives a robotized camera for obtaining detailed images of ears and silks. We first select, among 12 whole plant side views, those best suited for detecting ear position. Images are segmented, the stem pixels are labelled and the ear position is identified based on changes in width along the stem. A mobile camera is then automatically positioned in real time at 30 cm from the ear, for a detailed picture in which silks are identified based on texture and colour. This allows analysis of the time course of ear and silk growths of thousands of plants. The pipeline was tested on a panel of 60 maize hybrids in the PHENOARCH phenotyping platform. Over 360 plants, ear position was correctly estimated in 86% of cases, before it could be visually assessed. Silk growth rate, estimated on all plants, decreased with time consistent with literature. The pipeline allowed clear identification of the effects of genotypes and water deficit on the rate and duration of silk growth. Conclusions: The pipeline presented here, which combines computer vision, machine learning and robotics, provides a powerful tool for large-scale genetic analyses of the control of reproductive growth to changes in environmental conditions in a non-invasive and automatized way. It is available as Open Source software in the OpenAlea platform.

AB - [This corrects the article DOI: 10.1186/s13007-017-0166-6.]. PMID- 29177001 TI - A cautionary note on the use of chromosome conformation capture in plants. AB - Background: The chromosome conformation capture (3C) technique is a method to study chromatin interactions at specific genomic loci. Initially established for yeast the 3C technique has been adapted to plants in recent years in order to study chromatin interactions and their role in transcriptional gene regulation. As the plant scientific community continues to implement this technology, a discussion on critical controls, validations steps and interpretation of 3C data is essential to fully benefit from 3C in plants. Results: Here we assess the reliability and robustness of the 3C technique for the detection of chromatin interactions in Arabidopsis. As a case study, we applied this methodology to the genomic locus of a floral integrator gene SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1), and demonstrate the need of several controls and standard validation steps to allow a meaningful interpretation of 3C data. The intricacies of this promising but challenging technique are discussed in depth. Conclusions: The 3C technique offers an interesting opportunity to study chromatin interactions at a resolution infeasible by microscopy. However, for interpretation of 3C interaction data and identification of true interactions, 3C technology demands a stringent experimental setup and extreme caution. PMID- 29177002 TI - Non-invasive imaging of plant roots in different soils using magnetic resonance imaging (MRI). AB - Background: Root systems are highly plastic and adapt according to their soil environment. Studying the particular influence of soils on root development necessitates the adaptation and evaluation of imaging methods for multiple substrates. Non-invasive 3D root images in soil can be obtained using magnetic resonance imaging (MRI). Not all substrates, however, are suitable for MRI. Using barley as a model plant we investigated the achievable image quality and the suitability for root phenotyping of six commercially available natural soil substrates of commonly occurring soil textures. The results are compared with two artificially composed substrates previously documented for MRI root imaging. Results: In five out of the eight tested substrates, barley lateral roots with diameters below 300 um could still be resolved. In two other soils, only the thicker barley seminal roots were detectable. For these two substrates the minimal detectable root diameter was between 400 and 500 um. Only one soil did not allow imaging of the roots with MRI. In the artificially composed substrates, soil moisture above 70% of the maximal water holding capacity (WHCmax) impeded root imaging. For the natural soil substrates, soil moisture had no effect on MRI root image quality in the investigated range of 50-80% WHCmax. Conclusions: Almost all tested natural soil substrates allowed for root imaging using MRI. Half of these substrates resulted in root images comparable to our current lab standard substrate, allowing root detection down to a diameter of 300 um. These soils were used as supplied by the vendor and, in particular, removal of ferromagnetic particles was not necessary. With the characterization of different soils, investigations such as trait stability across substrates are now possible using noninvasive MRI. PMID- 29177003 TI - Corrigendum to "Comparative Sensitivity Analysis of Muscle Activation Dynamics". AB - [This corrects the article DOI: 10.1155/2015/585409.]. PMID- 29177004 TI - Active fraction (HS7) from Taiwanofungus camphoratus inhibits AKT-mTOR, ERK and STAT3 pathways and induces CDK inhibitors in CL1-0 human lung cancer cells. AB - Background: The non-small cell lung cancer (NSCLC) is the leading cause of cancer death worldwide. In NSCLC, the oncogenic AKT-mTOR, ERK and STAT3 pathways are commonly dysregulated and have emerged as attractive targets for therapeutic developments. In a relatively limited subset of NSCLC, these pathways driven by mutant EGFR can be treated by the tyrosine kinase inhibitors (TKIs)-mediated targeted therapy. However, for the most NSCLC, more novel targeted agents are imperatively needed. Therefore, we investigated the inhibitory effects of the active fraction HS7 from Taiwanofungus camphoratus, a unique medicinal fungus in Taiwan, on these pathways in CL1-0 EGFR wild-type human NSCLC cells. Methods: The active fraction HS7 was prepared by n-hexane extraction of T. camphoratus followed by silica gel chromatography. Its effects on the cell viabilities were determined by sulforhodamine B colorimetric assay. Flow cytometry was used to analyze cell-cycle regulation and apoptosis induction. The changes in cellular protein levels were examined by Western blot. Results: The active fraction HS7 vigorously inhibits AKT-mTOR, ERK and STAT3 signaling pathways in CL1-0 cells. At dose of 25 MUg/mL, these signaling pathways were almost completely inhibited by HS7, accompanied with induction of cyclin-dependent kinase inhibitors such as p15, p21 and p27. Accordingly, the AKT-mTOR downstream targets p-p70S6K and HIF 1alpha were also suppressed as well. At this dose, the cell proliferation was profoundly suppressed to 23.4% of control and apoptosis induction was observed. Conclusions: The active fraction HS7 from n-hexane extract of T. camphoratus exerts multi-targeting activity on the suppression of AKT-mTOR, ERK and STAT3 pathways and induction of p15, p21 and p27 in EGFR wild-type NSCLC cells. This multi-targeting activity of HS7 suggests its potential as an alternative medicine for the treatment of EGFR TKIs resistant NSCLC. PMID- 29177005 TI - Altered Pre-Ejection Period Response to Social Evaluative Threat in Adolescents with Autism Spectrum Disorder. AB - Introduction: The autonomic nervous system (ANS) is involved in regulating social behavior; Autism Spectrum Disorder (ASD) is characterized by alterations in social behavior and reduced physiological response to threat. We hypothesized that adolescents with ASD would show reduced ANS response to social threat. Methods: Eighteen males with ASD and thirteen males with typical development (TD), ages 12 to 17, completed a social threat paradigm while wearing an impedance cardiography apparatus. We calculated pre-ejection period (PEP) and tested for between-group differences in PEP response to social threat. We also conducted correlation analyses between PEP change scores and clinical symptom scales. Results: There was an effect of diagnosis on change in PEP from baseline to the onset of social threat (F=7.60, p=0.01), with greater changes in PEP in TD compared to ASD. PEP change score and the Social Communication Questionnaire (r=0.634, p=0.005) and the ADHD Problems Subscale of the Child Behavior Checklist (r=0.568, p=0.014) were correlated. Conclusions: These findings suggest reduced arousal in response to social threat in ASD, with preliminary evidence that reduced sympathetic activation is associated with increased social behavior symptoms. PMID- 29177007 TI - A simplified microwave-based motion detector for home cage activity monitoring in mice. AB - Background: Locomotor activity of rodents is an important readout to assess well being and physical health, and is pivotal for behavioral phenotyping. Measuring homecage-activity with standard and cost-effective optical methods in mice has become difficult, as modern housing conditions (e.g. individually ventilated cages, cage enrichment) do not allow constant, unobstructed, visual access. Resolving this issue either makes greater investments necessary, especially if several experiments will be run in parallel, or is at the animals' expense. The purpose of this study is to provide an easy, yet satisfying solution for the behavioral biologist at novice makers level. Results: We show the design, construction and validation of a simplified, low-cost, radar-based motion detector for home cage activity monitoring in mice. In addition we demonstrate that mice which have been selectively bred for low levels of anxiety-related behavior (LAB) have deficits in circadian photoentrainment compared to CD1 control animals. Conclusion: In this study we have demonstrated that our proposed low-cost microwave-based motion detector is well-suited for the study of circadian rhythms in mice. PMID- 29177006 TI - Tissue specific microenvironments: a key tool for tissue engineering and regenerative medicine. AB - The accumulated evidence points to the microenvironment as the primary mediator of cellular fate determination. Comprised of parenchymal cells, stromal cells, structural extracellular matrix proteins, and signaling molecules, the microenvironment is a complex and synergistic edifice that varies tissue to tissue. Furthermore, it has become increasingly clear that the microenvironment plays crucial roles in the establishment and progression of diseases such as cardiovascular disease, neurodegeneration, cancer, and ageing. Here we review the historical perspectives on the microenvironment, and how it has directed current explorations in tissue engineering. By thoroughly understanding the role of the microenvironment, we can begin to correctly manipulate it to prevent and cure diseases through regenerative medicine techniques. PMID- 29177008 TI - Deciphering cyanobacterial phenotypes for fast photoautotrophic growth via isotopically nonstationary metabolic flux analysis. AB - Background: Synechococcus elongatus UTEX 2973 is the fastest growing cyanobacterium characterized to date. Its genome was found to be 99.8% identical to S. elongatus 7942 yet it grows twice as fast. Current genome-to-phenome mapping is still poorly performed for non-model organisms. Even for species with identical genomes, cell phenotypes can be strikingly different. To understand Synechococcus 2973's fast-growth phenotype and its metabolic features advantageous to photo-biorefineries, 13C isotopically nonstationary metabolic flux analysis (INST-MFA), biomass compositional analysis, gene knockouts, and metabolite profiling were performed on both strains under various growth conditions. Results: The Synechococcus 2973 flux maps show substantial carbon flow through the Calvin cycle, glycolysis, photorespiration and pyruvate kinase, but minimal flux through the malic enzyme and oxidative pentose phosphate pathways under high light/CO2 conditions. During fast growth, its pool sizes of key metabolites in central pathways were lower than suboptimal growth. Synechococcus 2973 demonstrated similar flux ratios to Synechococcus 7942 (under fast growth conditions), but exhibited greater carbon assimilation, higher NADPH concentrations, higher energy charge (relative ATP ratio over ADP and AMP), less accumulation of glycogen, and potentially metabolite channeling. Furthermore, Synechococcus 2973 has very limited flux through the TCA pathway with small pool sizes of acetyl-CoA/TCA intermediates under all growth conditions. Conclusions: This study employed flux analysis to investigate phenotypic heterogeneity among two cyanobacterial strains with near-identical genome background. The flux/metabolite profiling, biomass composition analysis, and genetic modification results elucidate a highly effective metabolic topology for CO2 assimilatory and biosynthesis in Synechococcus 2973. Comparisons across multiple Synechococcus strains indicate faster metabolism is also driven by proportional increases in both photosynthesis and key central pathway fluxes. Moreover, the flux distribution in Synechococcus 2973 supports the use of its strong sugar phosphate pathways for optimal bio-productions. The integrated methodologies in this study can be applied for characterizing non-model microbial metabolism. PMID- 29177009 TI - Label-free, simultaneous quantification of starch, protein and triacylglycerol in single microalgal cells. AB - Background: Current approaches for quantification of major energy-storage forms in microalgae, including starch, protein and lipids, generally require cell cultivation to collect biomass followed by tedious and time-consuming analytical procedures. Thus, label-free, non-destructive and simultaneous quantification of such macromolecules at single-cell resolution is highly desirable in microalgal feedstock development and bioprocess control. Results: Here, we established a method based on single-cell Raman spectra (SCRS) that simultaneously quantifies the contents of starch, protein, triacylglycerol (TAG) and lipid unsaturation degree in individual Chlamydomonas reinhardtii cells. Measurement accuracy for the contents based on full SCRS spectrum each reached 96.86-99.24%, all significantly higher than single peak-based models. However, accuracy and reliability of measurement are dependent on the number of cells sampled, thus a formal mathematical framework was proposed and validated to rationally define "minimal sampling depth" for a given state of cellular population. Furthermore, a barcode consisting of 13 marker Raman peaks was proposed to characterize the temporal dynamics of these energy-storage products, which revealed that the average contents of starch and TAG increased, while their heterogeneity indices decreased, with those of protein being exactly the opposite. Finally, our method is widely applicable, as measurements among cells from liquid suspension culture, wet paste and frozen dried powder all exhibited excellent consistency. Conclusions: When sampled at proper depth, SCRS can serve as a quantitative and generally applicable tool for characterization and screening of strains and bioprocesses based on the profile of energy-storage macromolecules and their among-cell heterogeneity. PMID- 29177010 TI - 7p15 deletion as the cause of hand-foot-genital syndrome: a case report, literature review and proposal of a minimum region for this phenotype. AB - Background: Hand-foot-genital syndrome (HFGS) is a rare condition characterized by congenital malformations in the limbs and genitourinary tract. Generally, this syndrome occurs due to point mutations that cause loss of function of the HOXA13 gene, which is located on 7p15; however, there are some patients with HFGS caused by interstitial deletions in this region. Case presentation: We describe a pediatric Mexican patient who came to the Medical Genetics Department at the National Institute of Pediatrics because he presented with genital, hand and feet anomalies, facial dysmorphisms, and learning difficulties. Array CGH reported a 12.7 Mb deletion that includes HOXA13. Conclusions: We compared our patient with cases of HFGS reported in the literature caused by a microdeletion; we found a minimum shared region in 7p15.2. By analyzing the phenotype in these patients, we suggest that microdeletions in this region should be investigated in all patients with clinical characteristics of HFGS who also present with dysplastic ears, mainly low-set implantation with a prominent antihelix, as well as a low nasal bridge and long philtrum.

AB - Background: Small supernumerary marker chromosomes can be derived from autosomes and sex chromosomes and can accompany chromosome pathologies, such as Turner syndrome. Case presentation: Here, we present a case report of a patient with mosaic Turner syndrome and Dandy-Walker syndrome carrying a marker chromosome. We showed the presence of the marker chromosome in 33.8% of blood cells. FISH of the probe derived from the marker chromosome by microdissection revealed that it originated from the centromeric region of chromosome X. Additionally, we showed no telomeric sequences and no XIST sequence in the marker chromosome. This is the first report of these two syndromes accompanied by the presence of a marker chromosome. Conclusion: Marker chromosome was X-derived and originated from centromeric region. Patient has mild symptoms but there is no XIST gene in marker chromosome. Trial registration: CPG137.

AB - Background: Many bacteria and archaea possess a defense system called clustered regularly interspaced short palindromic repeats (CRISPR) associated proteins (CRISPR-Cas system) against invaders such as phages or plasmids. This system has not been demonstrated in Helicobacter pylori. The numbers of spacer in CRISPR array differ among bacterial strains and can be used as a genetic marker for bacterial typing. Results: A total of 36 H. pylori isolates were collected from patients in three hospitals located in the central (PBH) and southern (SKH) regions of Thailand. It is of interest that CRISPR-like sequences of this bacterium were detected in vlpC encoded for VacA-like protein C. Virulence genes were investigated and the most pathogenic genotype (cagA vacA s1m1) was detected in 17 out of 29 (58.6%) isolates from PBH and 5 out of 7 (71.4%) from SKH. vapD gene was identified in each one isolate from PBH and SKH. CRISPR-like sequences and virulence genes of 20 isolates of H. pylori obtained in this study were analyzed and CRISPR-virulence typing was constructed and compared to profiles obtained by the random amplification of polymorphic DNA (RAPD) technique. The discriminatory power (DI) of CRISPR-virulence typing was not different from RAPD typing. Conclusion: CRISPR-virulence typing in H. pylori is easy and reliable for epidemiology and can be used for inter-laboratory interpretation.

PMID- 29177013 TI - Vitamin D is associated with metabotropic but not neurotrophic effects of exercise in ovariectomized rats. AB - Purpose: Here, we studied the beneficial effects of aerobic exercise on metabolic syndrome components, cognitive performance, brain derived neurotrophic factor (BDNF) and irisin in ovariectomized rats with different serum vitamin D (Vit D) status. Methods: Eighty female wistar rats were divided into 2 groups of sham operated (sham, n = 8), and ovariectomized (OVX, n = 72). Then OVX were divided into 9 groups of receiving combination of exercise protocol with low dose of Vit D (OVX + EXE + LD), high dose of Vit D (OVX + EXE + HD), Vit D deficiency (OVX + EXE - D), and (OVX + EXE + Veh). Also non exercised groups of OVX receiving high dose of Vit D (OVX + HD), low dose of Vit D (OVX + LD), Vit D deficiency (OVX - D), and Veh (OVX + Veh) were included. After 2 months of related interventions, spatial memory was assessed using Morris water maze (MWM), and then metabolic syndrome components were measured. Results: High dose of Vit D supplementation showed significant reduction in weight (p = 0.001), lipid profiles (p = 0.001), visceral fat (p = 0.001) and waist circumference (p = 0.001) regardless of exercising or not, with no change in cognitiive function. Serum BDNF level was significantly higher in Vit D deficient group (p = 0.001), and was decreased in the OVX + HD. In contrary, irisin did not show any significant relationship with serum concentration of Vit D, while it was significantly elevated in the exercised groups compared with non-exercised counterparts. Conclusion: Vit D insufficiency deteriorates metabolic syndrome components, and elevates serum BDNF as a compensatory metabotropic factor, and further supplementation significantly attenuates these components parallel with reduction in BDNF. In addition, aerobic exercise successfully induces various metabolic benefits, provided optimum serum level of Vit D.

He had history of right heart failure on several occasions in the past, and one of these admissions prompted referral to a cardiac specialist. On examination, he had markedly elevated jugular venous pressure with prominent 'y descent', a tricuspid regurgitation murmur, gross ascites and pedal oedema. A full blood count, routine biochemical screen and serum bicarbonate levels were normal. Right ventricular angiogram revealed a 'caterpillar'-like aneurysm of the right ventricle (RV) apex (figure 1 arrow) with a dilated right ventricular outflow tract and significant tricuspid regurgitation with a dilated right atrium (see online supplementary video 1).

PMID- 29177015 TI - Clinical significance of atrial high-rate episodes for thromboembolic events in Japanese population. AB - Objective: The clinical significance of atrial high-rate episodes (AHREs) detected by cardiac devices among patients with implantable pacemakers has recently emerged. However, the relationship between AHREs and ischaemic stroke and systemic embolism (SE) is not well understood in the Japanese population. Methods: This study included 343 patients with pacemakers capable of continuous atrial rhythm monitoring (167 males; mean age, 80+/-7 years). Atrial tachyarrhythmia detection was programmed to the nominal setting of each device, and AHRE was defined as any episode of sustained atrial tachyarrhythmia lasting for more than 6 min. Thromboembolic risk was defined based on the CHADS2 score. Results: During the follow-up period (52+/-30 months), 165 (48%) patients had at least one episode of AHREs, and 19 (6%) patients experienced stroke/SE. Among patients who experienced stroke/SE, 14 had AHREs before the stroke/SE. AHREs were significantly associated with stroke/SE (HR 2.87; 95% CI 1.10 to 8.90; p=0.03). Subgroup analysis conducted to investigate the impact of the CHADS2 score severity on stroke/SE revealed that AHREs were not associated with stroke/SE in patients with low or intermediate thromboembolic risk (CHADS2 score 0-2; n=217). In contrast, among patients with high thromboembolic risk (CHADS2 score>2; n=126), there was a significant association between AHREs and the incidence of stroke/SE (HR 3.73; 95% CI 1.06 to 13.1; p=0.04). Conclusion: AHREs detected by pacemaker were associated with ischaemic stroke/SE in the Japanese population. However, this association was observed only in the high thromboembolic risk group. PMID- 29177017 TI - Iatrogenic radial arteriovenous fistula. PMID- 29177018 TI - Study of the association between gait variability and physical activity. AB - Background: Gait variability can be considered an indirect measure of gait stability, in particular regarding temporal or spatial variability assessment. Physical activity, such as walking, is advised for the elderly and can be improved by gait stability. The aim of this study was to investigate the associations between gait stability and physical activity in women of different age ranges. Methods: Forty-two healthy women of different age ranges (18-40 yrs. and 65-75 yrs.) were recruited in the study. To assess physical activity, the subjects wore a multi-sensor activity monitor for a whole week, inferring the time spent in moderate to vigorous physical activity (MVPA). MVPA were analysed in bouts of at least 10 subsequent minutes (MVPAbouts) and in overall minutes (MVPAtot). A kinematic analysis was performed with an optoelectronic system to calculate gait variability - expressed as standard deviation (SD) and coefficient of variability (CV) of step width, stride length, stance and swing time (during treadmill walking at different speeds). Results: Elderly women, with high walking speed (5 km/h), and moderate step width variability (CV = 8-27%), met the recommended levels of physical activity (MVPAtot and MVPAbouts). Furthermore, gait variability, adjusted for age and number of falls, was significantly and negatively associated with MVPAtot only at 3.5 km/h, and with MVPAbouts only at 4 km/h. Conclusions: In a population of healthy elderly women, gait variability was significantly and negatively associated with the level of physical activity. Healthy elderly women, with moderate gait variability (step width variability), and high preferred walking speed, seem to be able to meet the recommended levels of physical activity. PMID- 29177019 TI - Ovarian and Breast Cancer Migration Dynamics on Laminin and Fibronectin Bidirectional Gradient Fibers Fabricated via Multiphoton Excited Photochemistry. AB - Introduction: Migration mis-regulation is a hallmark of cancer, and remains an important problem in cancer biology. We postulate the needs for better in vitro models to understand the details of cell-matrix interactions. Here, we utilized multiphoton excited (MPE) photochemistry to fabricate models to systematically study migration dynamics operative in breast and ovarian cancer. Gradients are a convenient means to modulate concentration and also have been implicated in metastases. Methods: We specifically pattern sub-micron structured gradients from laminin and fibronectin whose up-regulation is associated with increased metastasis and poor prognosis. We developed a new continuous linear bi directional gradient design, permitting exploration of the underlying cell-matrix interactions of migration, including speed, directness, and f-actin cytoskeleton alignment as a function of concentration. These new models provide both contact guidance and ECM binding cues, and provide a more relevant environment than possible with existing technologies such as flow chambers or 2D printed surfaces. Results: We found an overall increase in these processes with increasing concentration on both laminin and fibronectin gradients for a series of ovarian and breast cancer lines. Moreover, directness was higher for more metastatic cells, indicating that epithelial or mesenchymal state of the cell type governs the dynamics. However, the specifics of the speed and directedness depend on both the cell type and protein, thus we found that we must consider these processes collectively to obtain a self-consistent picture of the migration. For this purpose, we performed a linear discriminate analysis (LDA) and successfully classified the different cell types on the two protein gradients without molecular biology analysis. Conclusions: The bi-gradient structures are versatile tools to performing detailed studies of cell migration, specifically haptotxis. We further suggest the can be used in assessing efficacy of drug treatments targeted at specific matrix components.

AB - Romberg extrapolation is a long-known method to improve the convergence rate of the trapezoidal rule on intervals. For simple regions such as the cube [Formula: see text] it is directly transferable to cubature in q dimensions. In this paper, we formulate Romberg extrapolation for Euler summation-based cubature on arbitrary q-dimensional regular regions [Formula: see text] and derive an explicit representation for the remainder term. PMID- 29177022 TI - Toward a Progress Indicator for Machine Learning Model Building and Data Mining Algorithm Execution: A Position Paper. AB - For user-friendliness, many software systems offer progress indicators for long duration tasks. A typical progress indicator continuously estimates the remaining task execution time as well as the portion of the task that has been finished. Building a machine learning model often takes a long time, but no existing machine learning software supplies a non-trivial progress indicator. Similarly, running a data mining algorithm often takes a long time, but no existing data mining software provides a nontrivial progress indicator. In this article, we consider the problem of offering progress indicators for machine learning model building and data mining algorithm execution. We discuss the goals and challenges intrinsic to this problem. Then we describe an initial framework for implementing such progress indicators and two advanced, potential uses of them, with the goal of inspiring future research on this topic. PMID- 29177020 TI - Epigenetic regulation of AXL and risk of childhood asthma symptoms. AB - Background: AXL is one of the TAM (TYRO3, AXL and MERTK) receptor tyrosine kinases and may affect numerous immune-related health conditions. However, the role for AXL in asthma, including its epigenetic regulation, has not been extensively studied. Methods: We investigated the association between AXL DNA methylation at birth and risk of childhood asthma symptoms at age 6 years. DNA methylation of multiple CpG loci across the regulatory regions of AXL was measured in newborn bloodspots using the Illumina HumanMethylation450 array on a subset of 246 children from the Children's Health Study (CHS). Logistic regression models were fitted to assess the association between asthma symptoms and DNA methylation. Findings were evaluated for replication in a separate population of 1038 CHS subjects using Pyrosequencing on newborn bloodspot samples. AXL genotypes were extracted from genome-wide data. Results: Higher average methylation of CpGs in the AXL gene at birth was associated with higher risk of parent-reported wheezing, and the association was stronger in girls than in boys. This relationship reflected the methylation status of the gene-body region near the 5' end, for which a 1% higher methylation level was significantly associated with a 72% increased risk of ever having wheezed by 6 years. The association of one CpG locus, cg00360107 was replicated using Pyrosequencing. Increased AXL methylation was also associated with lower mRNA expression level of this gene in lung tissue from the Cancer Genome Atlas (TCGA) dataset. Furthermore, AXL DNA methylation was strongly linked to underlying genetic polymorphisms. Conclusions: AXL DNA methylation at birth was associated with higher risk for asthma-related symptoms in early childhood. PMID- 29177023 TI - Adolescents and Self-Reported Physical Activity: An Evaluation of the Modified Godin Leisure-Time Exercise Questionnaire. AB - The Godin Leisure-Time Exercise Questionnaire assesses self-reported physical activity (PA) among adults, and was later modified for children. However, the modified version (Godin-Child Questionnaire) has not been validated among adolescents. This study evaluates the construct validity and test-retest reliability of the Godin-Child Questionnaire among adolescents. The study participants, sixth graders (age M= 11.06 +/- 0.436; 48% males, 48% Latino), were assessed at 2 time points (fall and spring: N= 139). First, the study determined whether adolescents accurately reported exercise intensity based on adolescents' ratings of perceived exertion (RPE) during moderate- and hard-intensity exercise tasks. Second, objective assessments of PA obtained using the Actigraph(r) accelerometer were correlated with PA self-reported on the Godin-Child Questionnaire. Third, test-retest correlations evaluated the Godin-Child Questionnaire for its reliability. Finally, interviews explored participants' interpretations of the Godin-Child Questionnaire. RPEs suggested that adolescents generally perceived exercise intensity accurately, with no significant differences between genders. There was a weak correlation between the Godin-Child Questionnaire and the Actigraph(r) during fall (r=.22, P< .05) and spring (r=.24, P<.05), with a significant correlation for males (P<.05) at both time periods. Test-retest correlations were acceptable (fall-spring r=.68; P<.001) and were equally strong among females and males. Interviews revealed that some respondents overlooked written directions. The Godin-Child Questionnaire may be a useful evaluative measure of self-reported physical activity for comparing activity levels across groups of adolescents, but may be less accurate for assessing physical activity on an individual level. PMID- 29177024 TI - Epidemiology of fragility fractures and fall prevention in the elderly: a systematic review of the literature. AB - Fragility fractures in the elderly is an ongoing concern for orthopaedic surgeons. A 50-year-old woman has a 40% chance of having a vertebral compression fracture in her lifetime. The incidence of vertebral fractures, reported to be more than 10 times higher than that of femoral fractures, is estimated as 1-1.5 million per year in Japan. Vertebral fractures often occur without a fall, whereas the majority of nonvertebral fractures are the consequence of falls; the site of the nonvertebral fracture appears to be dictated by the type of fall. Distal radial fractures commonly occur as a consequence of hand protection during the fall. In older patients, falling load tends to directly affect shoulder and hip joints and lead to proximal humeral and femoral fractures. The incidence of vertebral fractures is increased in women over 50 yr of age, following the same trend as osteoporosis prevalence. Conversely, the mean age for proximal femoral fractures is around 80 yr, and more than 75% of femoral fractures occur in individuals over the age of 75. The prognostic risk of aging is 11-fold greater than that of reduced bone mineral density, and age is another risk factor for femoral fractures. Prophylactic therapy for osteoporosis and femoral fractures was shown to more effective in women in their 70s than in those over the age of 80. Although several approaches, including exercise therapy, vitamin D administration, and environmental adjustment at home, have been reported to be effective in fall prevention, effective fracture prevention approaches in frail elderly individuals have not yet been well established. PMID- 29177026 TI - 2-Way k-Means as a Model for Microbiome Samples. AB - Motivation. Microbiome sequencing allows defining clusters of samples with shared composition. However, this paradigm poorly accounts for samples whose composition is a mixture of cluster-characterizing ones and which therefore lie in between them in the cluster space. This paper addresses unsupervised learning of 2-way clusters. It defines a mixture model that allows 2-way cluster assignment and describes a variant of generalized k-means for learning such a model. We demonstrate applicability to microbial 16S rDNA sequencing data from the Human Vaginal Microbiome Project. PMID- 29177025 TI - Acute Exposure to Cigarette Smoking Followed by Myocardial Infarction Aggravates Renal Damage in an In Vivo Mouse Model. AB - Cigarette smoking (S) is a risk factor for progressive chronic kidney disease, renal dysfunction, and renal failure. In this study, the effect of smoking on kidney function was investigated in a mouse model of myocardial infarction (MI) using 4 groups: control (C), smoking (S), MI, and S+MI. Histological analysis of S+MI group showed alterations in kidney structure including swelling of the proximal convoluted tubules (PCTs), thinning of the epithelial lining, focal loss of the brush border of PCTs, and patchy glomerular retraction. Molecular analysis revealed that nephrin expression was significantly reduced in the S+MI group, whereas sodium-hydrogen exchanger-1 (NHE-1) was significantly increased, suggesting altered glomerular filtration and kidney functions. Moreover, S+MI group, but not S alone, showed a significant increase in the expression of connective tissue growth factor (CTGF) and fibrotic proteins fibronectin (FN) and alpha-smooth muscle actin (SMA), in comparison to controls, in addition to a significant increase in mRNA levels of IL-6 and TNF-alpha inflammatory markers. Finally, reactive oxygen species (ROS) production was significantly accentuated in S+MI group concomitant with a significant increase in NOX-4 protein levels. In conclusion, smoking aggravates murine acute renal damage caused by MI at the structural and molecular levels by exacerbating renal dysfunction. PMID- 29177027 TI - Combination of Deep Recurrent Neural Networks and Conditional Random Fields for Extracting Adverse Drug Reactions from User Reviews. AB - Adverse drug reactions (ADRs) are an essential part of the analysis of drug use, measuring drug use benefits, and making policy decisions. Traditional channels for identifying ADRs are reliable but very slow and only produce a small amount of data. Text reviews, either on specialized web sites or in general-purpose social networks, may lead to a data source of unprecedented size, but identifying ADRs in free-form text is a challenging natural language processing problem. In this work, we propose a novel model for this problem, uniting recurrent neural architectures and conditional random fields. We evaluate our model with a comprehensive experimental study, showing improvements over state-of-the-art methods of ADR extraction.

A cutaneous microdialysis study in penicillin-allergic patients. AB - Background: Diagnostic workup of penicillin allergy comprises skin testing with penicillins, and patients are deemed allergic if skin test is positive. However, the literature suggests that skin test-positive patients may be challenge negative, indicating that the skin test may be falsely positive. Objective: To investigate real-time histamine release from a positive intracutaneous test induced by penicillin in patients with positive and negative challenges to penicillin. Methods: Skin microdialysis was performed in 21 penicillin-allergic patients with positive skin test, 13 non-allergic volunteers serving as negative controls, and 7 grass pollen-allergic patients serving as positive controls. Histamine was measured by microdialysis after skin test with penicillin/grass/NaCl. Penicillin challenge was subsequently performed in 12 of the patients. Results: Only 10/21 patients (47.6%) were skin test positive at microdialysis. During microdialysis 13 single intracutaneous tests were positive and histamine was detected in 4/13 occurring in four challenge positive patients. Thirteen/21 patients (61.9%) were deemed allergic to penicillin; eight had positive skin test. Two patients with positive skin test were challenge negative. In grass pollen allergic patients, 7/7 had a positive intracutaneous test to grass and all released histamine in the wheals. All 13 negative controls had negative intracutaneous test to penicillin and no histamine release. Conclusion: Histamine was only detected in the minority of positive intracutaneous tests with penicillin in penicillin-allergic patients. Other mediators may be involved. PMID- 29177029 TI - Tumorigenesis as a process of gradual loss of original cell identity and gain of properties of neural precursor/progenitor cells. AB - Cancer is a complex disease without a unified explanation for its cause so far. Our recent work demonstrates that cancer cells share similar regulatory networks and characteristics with embryonic neural cells. Based on the study, I will address the relationship between tumor and neural cells in more details. I collected the evidence from various aspects of cancer development in many other studies, and integrated the information from studies on cancer cell properties, cell fate specification during embryonic development and evolution. Synthesis of the information strongly supports that cancer cells share much more similarities with neural progenitor/stem cells than with mesenchymal-type cells and that tumorigenesis represents a process of gradual loss of cell or lineage identity and gain of characteristics of neural cells. I also discuss cancer EMT, a concept having been under intense debate, and possibly the true meaning of EMT in cancer initiation and development. This synthesis provides fresh insights into a unified explanation for and a previously unrecognized nature of tumorigenesis, which might not be revealed by studies on individual molecular events. The review will also present some brief suggestions for cancer research based on the proposed model of tumorigenesis. PMID- 29177031 TI - A protocol for clinical trial study of the effect of core stabilization exercises on spine kinematics during gait with and without load in patients with non specific chronic low back pain. AB - Background: Non-specific chronic low back pain (NCLBP) is a major public health and global socioeconomic burden with a variety of symptoms such as gait abnormality. Trunk stiffness and deep trunk muscles dysfunction known as guarding mechanism in gait are factors leading to abnormal movement pattern of the spine. Anterior load carriage task during gait is also challenged the trunk stability and its movement pattern. It will be therefore of interest to examine the effect of a Core Stabilization Training Program (CSTP) on the trunk and pelvis kinematics including variability and peak displacement during gait with and without load in NCLBP patients. Methods: Patients with NCLBP will participate in a program containing 16 sessions of CSTP and perceived pain, disability and kinematic will be evaluated with 100 mm visual analog scale (VAS), Oswestry Disability Index (ODI) and motion analyzing system respectively before and after the intervention. Participants will be asked to walk with self-selected comfortable speed for 3 times without load and 3 times with caring a load with hands. Discussions: We will quantify the effectiveness of CSTP on the kinematic of trunk, lumbar and pelvis during gait. Comparing the kinematic pattern and movement variability using CVo and CVp can contribute to better understand the motor control strategy and movement pattern of the spine during an anterior load carriage task between patients with NCLBP and healthy.

PMID- 29177032 TI - Stable isotopes can be used to infer the overwintering locations of prebreeding marine birds in the Canadian Arctic. AB - Although assessments of winter carryover effects on fitness-related breeding parameters are vital for determining the links between environmental variation and fitness, direct methods of determining overwintering distributions (e.g., electronic tracking) can be expensive, limiting the number of individuals studied. Alternatively, stable isotope analysis in specific tissues can be used as an indirect means of determining individual overwintering areas of residency. Although increasingly used to infer the overwintering distributions of terrestrial birds, stable isotopes have been used less often to infer overwintering areas of marine birds. Using Arctic-breeding common eiders, we test the effectiveness of an integrated stable isotope approach (13-carbon, 15 nitrogen, and 2-hydrogen) to infer overwintering locations. Knowing the overwinter destinations of eiders from tracking studies at our study colony at East Bay Island, Nunavut, we sampled claw and blood tissues at two known overwintering locations, Nuuk, Greenland, and Newfoundland, Canada. These two locations yielded distinct tissue-specific isotopic profiles. We then compared the isotope profiles of tissues collected from eiders upon their arrival at our breeding colony, and used a k-means cluster analysis approach to match arriving eiders to an overwintering group. Samples from the claws of eiders were most effective for determining overwinter origin, due to this tissue's slow growth rate relative to the 40-day turnover rate of blood. Despite taking an integrative approach using multiple isotopes, k-means cluster analysis was most effective when using 13-carbon alone to assign eiders to an overwintering group. Our research demonstrates that it is possible to use stable isotope analysis to assign an overwintering location to a marine bird. There are few examples of the effective use of this technique on a marine bird at this scale; we provide a framework for applying this technique to detect changes in the migration phenology of birds' responses to rapid changes in the Arctic. PMID- 29177033 TI - Evolutionarily significant units of the critically endangered leaf frog Pithecopus ayeaye (Anura, Phyllomedusidae) are not effectively preserved by the Brazilian protected areas network. AB - Protected areas (PAs) are essential for biodiversity conservation, but their coverage is considered inefficient for the preservation of all species. Many species are subdivided into evolutionarily significant units (ESUs) and the effectiveness of PAs in protecting them needs to be investigated. We evaluated the usefulness of the Brazilian PAs network in protecting ESUs of the critically endangered Pithecopus ayeaye through ongoing climate change. This species occurs in a threatened mountaintop ecosystem known as campos rupestres. We used multilocus DNA sequences to delimit geographic clusters, which were further validated as ESUs with a coalescent approach. Ecological niche modeling was used to estimate spatial changes in ESUs' potential distributions, and a gap analysis was carried out to evaluate the effectiveness of the Brazilian PAs network to protect P. ayeaye in the face of climate changes. We tested the niche overlap between ESUs to gain insights for potential management alternatives for the species. Pithecopus ayeaye contains at least three ESUs isolated in distinct mountain regions, and one of them is not protected by any PA. There are no climatic niche differences between the units, and only 4% of the suitable potential area of the species is protected in present and future projections. The current PAs are not effective in preserving the intraspecific diversity of P. ayeaye in its present and future range distributions. The genetic structure of P. ayeaye could represent a typical pattern in campos rupestres endemics, which should be considered for evaluating its conservation status. PMID- 29177034 TI - Maximum-likelihood approaches reveal signatures of positive selection in BMP15 and GDF9 genes modulating ovarian function in mammalian female fertility. AB - Bone morphogenetic proteins (BMPs) and the growth factors (GDFs) play an important role in ovarian folliculogenesis and essential regulator of processes of numerous granulosa cells. BMP15 gene variations linked to various ovarian phenotypic consequences subject to the species, from infertility to improved prolificacy in sheep, primary ovarian insufficiency in women or associated with minor subfertility in mouse. To study the evolving role of BMP15 and GDF9, a phylogenetic analysis was performed. To find out the candidate gene associated with prolificacy in mammals, the nucleotide sequence of BMP15 and GDF9 genes was recognized under positive selection in various mammalian species. Maximum likelihood approaches used on BMP15 and GDF9 genes exhibited a robust divergence and a prompted evolution as compared to other TGFbeta family members. Furthermore, among 32 mammalian species, we identified positive selection signals in the hominidae clade resulting to 132D, 147E, 163Y, 191W, and 236P codon sites of BMP15 and 162F, 188K, 206R, 240A, 244L, 246H, 248S, 251D, 253L, 254F and other codon sites of GDF9. The positively selected amino acid sites such as Alanine, Lucien, Arginine, and lysine are important for signaling. In conclusion, this study evidences that GDF9 and BMP15 genes have rapid evolution than other TGFbeta family members and was subjected to positive selection in the mammalian clade. Selected sites under the positive selection are of remarkable significance for the particular functioning of the protein and consequently for female fertility. PMID- 29177035 TI - Predicting individual plant performance in grasslands. AB - Plant functional traits are widely used to predict community productivity. However, they are rarely used to predict individual plant performance in grasslands. To assess the relative importance of traits compared to environment, we planted seedlings of 20 common grassland species as phytometers into existing grassland communities varying in land-use intensity. After 1 year, we dug out the plants and assessed root, leaf, and aboveground biomass, to measure plant performance. Furthermore, we determined the functional traits of the phytometers and of all plants growing in their local neighborhood. Neighborhood impacts were analyzed by calculating community-weighted means (CWM) and functional diversity (FD) of every measured trait. We used model selection to identify the most important predictors of individual plant performance, which included phytometer traits, environmental conditions (climate, soil conditions, and land-use intensity), as well as CWM and FD of the local neighborhood. Using variance partitioning, we found that most variation in individual plant performance was explained by the traits of the individual phytometer plant, ranging between 19.30% and 44.73% for leaf and aboveground dry mass, respectively. Similarly, in a linear mixed effects model across all species, performance was best predicted by phytometer traits. Among all environmental variables, only including land-use intensity improved model quality. The models were also improved by functional characteristics of the local neighborhood, such as CWM of leaf dry matter content, root calcium concentration, and root mass per volume as well as FD of leaf potassium and root magnesium concentration and shoot dry matter content. However, their relative effect sizes were much lower than those of the phytometer traits. Our study clearly showed that under realistic field conditions, the performance of an individual plant can be predicted satisfyingly by its functional traits, presumably because traits also capture most of environmental and neighborhood conditions. PMID- 29177036 TI - Sexual dimorphism, phenotypic integration, and the evolution of head structure in casque-headed lizards. AB - Sexes can differ in features associated with differential reproduction, which can be used during courtship or aggressive encounters. Some traits tend to evolve independently between sexes and emerge as sexually dimorphic within the organismal phenotype. We characterize such a relationship by estimating the phenotypic integration of the head morphology and modularity of the crest in the casque-headed lizards (Corytophanidae). In this clade, some species show extreme sexual dimorphism (e.g., head crests in the genus Basiliscus) while in others, both sexes are monomorphic. To characterize these patterns, we define phenotypic integration at the interspecific level as a pattern or network of traits evidenced by phylogenetically adjusted correlations that persist among species. At this level, modularity is an increased connectedness (e.g., higher correlation) among sections of these networks that persist in a lineage during the evolution of complex phenotypes. To test both concepts, we used phylogenetic geomorphometrics to characterize the head structure of corytophanid lizards, based on a time-calibrated phylogeny that includes candidate fossil ancestors. We found evidence of an older diversification of corytophanids than previously reported (~67 vs. ~23.5 MYA) and show that this clade includes two morphological head architectures: (1) Sexually dimorphic crests present in males that are evolving independently from the rest of the head structure, and (2) full integration of the head morphology in monomorphic species. We propose that both architectures are optimal evolutionary trajectories of the parietal crest bones in the head of these lizards. In sexually dimorphic species, these bones are elongated and thinner, and gave rise to the extended crest used in male courtship displays. In monomorphic species, the parietal crest grew thicker in both sexes to allow for a better insertion of muscles associated with a stronger bite. PMID- 29177037 TI - Unexpected mosaic distribution of two hybridizing sibling lineages in the teleplanically dispersing snail Stramonita haemastoma suggests unusual postglacial redistribution or cryptic invasion. AB - Molecular approaches have proven efficient to identify cryptic lineages within single taxonomic entities. Sometimes these cryptic lineages maybe previously unreported or unknown invasive taxa. The genetic structure of the marine gastropod Stramonita haemastoma has been examined in the Western Mediterranean and North-Eastern Atlantic populations with mtDNA COI sequences and three newly developed microsatellite markers. We identified two cryptic lineages, differentially fixed for alternative mtDNA COI haplogroups and significantly differentiated at microsatellite loci. The mosaic distribution of the two lineages is unusual for a warm-temperate marine invertebrate with a teleplanic larval stage. The Atlantic lineage was unexpectedly observed as a patch enclosed in the north of the Western Mediterranean Sea between eastern Spain and the French Riviera, and the Mediterranean lineage was found in Macronesian Islands. Although cyto-nuclear disequilibrium is globally maintained, asymmetric introgression occurs in the Spanish region where the two lineages co-occur in a hybrid zone. A first interpretation of our results is mito-nuclear discordance in a stable postglacial hybrid zone. Under this hypothesis, though, the location of genetic discontinuities would be unusual among planktonic dispersers. An alternative interpretation is that the Atlantic lineage, also found in Senegal and Venezuela, has been introduced by human activities in the Mediterranean area and is introgressing Mediterranean genes during its propagation, as theoretically expected. This second hypothesis would add an additional example to the growing list of cryptic marine invasions revealed by molecular studies. PMID- 29177039 TI - Corrigendum.

PMID- 29177038 TI - Genetic divergence between two phenotypically distinct bottlenose dolphin ecotypes suggests separate evolutionary trajectories. AB - Due to their worldwide distribution and occupancy of different types of environments, bottlenose dolphins display considerable morphological variation. Despite limited understanding about the taxonomic identity of such forms and connectivity among them at global scale, coastal (or inshore) and offshore (or oceanic) ecotypes have been widely recognized in several ocean regions. In the Southwest Atlantic Ocean (SWA), however, there are scarce records of bottlenose dolphins differing in external morphology according to habitat preferences that resemble the coastal-offshore pattern observed elsewhere. The main aim of this study was to analyze the genetic variability, and test for population structure between coastal (n = 127) and offshore (n = 45) bottlenose dolphins sampled in the SWA to assess whether their external morphological distinction is consistent with genetic differentiation. We used a combination of mtDNA control region sequences and microsatellite genotypes to infer population structure and levels of genetic diversity. Our results from both molecular marker types were congruent and revealed strong levels of structuring (microsatellites FST = 0.385, p < .001; mtDNA FST = 0.183, p < .001; PhiST = 0.385, p < .001) and much lower genetic diversity in the coastal than the offshore ecotype, supporting patterns found in previous studies elsewhere. Despite the opportunity for gene flow in potential "contact zones", we found minimal current and historical connectivity between ecotypes, suggesting they are following discrete evolutionary trajectories. Based on our molecular findings, which seem to be consistent with morphological differentiations recently described for bottlenose dolphins in our study area, we recommend recognizing the offshore bottlenose dolphin ecotype as an additional Evolutionarily Significant Unit (ESU) in the SWA. Implications of these results for the conservation of bottlenose dolphins in SWA are also discussed. PMID- 29167731 TI - Optimized purification strategies for the elimination of non-specific products in the isolation of GAD65-specific monoclonal autoantibodies. AB - Autoantibodies against antigens expressed by insulin-producing beta cells are circulating in both healthy individuals and patients at risk of developing Type 1 diabetes. Recent studies suggest that another set of antibodies (anti-idiotypic antibodies) exists in this antibody/antigen interacting network to regulate auto reactive responses. Anti-idiotypic antibodies may block the antigen-binding site of autoantibodies or inhibit autoantibody expression and secretion. The equilibrium between autoantibodies and anti-idiotypic antibodies plays a critical role in mediating or preventing autoimmunity. In order to investigate the molecular mechanisms underlying such a network in autoimmunity and potentially develop neutralizing reagents to prevent or treat Type 1 diabetes, we need to produce autoantibodies and autoantigens with high quality and purity. Herein, using GAD65/anti-GAD65 autoantibodies as a model system, we aimed to establish reliable approaches for the preparation of highly pure autoantibodies suitable for downstream investigation.

AB - Clinical trial consent for protocols and their revisions should be transparent for patients and traceable for stakeholders. Our goal is to implement a process allowing the collection of patients' informed consent, which is bound to protocol revisions, storing and tracking the consent in a secure, unfalsifiable and publicly verifiable way, and enabling the sharing of this information in real time. For that, we will built a consent workflow using a rising technology called Blockchain. This is a distributed technology that brings a built-in layer of transparency and traceability. Additionally, it removes the need for third parties, and gives participative control to the peer-to-peer users. From a more general and prospective point of view, we believe Blockchain technology brings a paradigmatical shift to the entire clinical research field. We designed a Proof of-Concept protocol consisting of time-stamping each step of the patient's consent collection using Blockchain; thus archiving and historicising the consent through cryptographic validation in a securely unfalsifiable and transparent way. For each revision of the protocol, consent was sought again. We obtained a single document, in a standard open format, that accounted for the whole consent collection process: timestamped consent status with regards to each version of the protocol. This document cannot be corrupted, and can be checked on any dedicated public website. It should be considered as a robust proof of data. In the future, we think that the complex data flow of a clinical trial can be tracked using Blockchain. Moreover, a blockchain core functionality, named Smart Contract, can help prevent clinical trial events not to happen in the right chronological order: including patients before they consented or analysing case report forms data before freezing the database. This will help reaching reliability, security, and transparency, and could be a consistent step towards reproducibility.

PMID- 29167733 TI - A 4-week, lifestyle-integrated, home-based exercise training programme elicits improvements in physical function and lean mass in older men and women: a pilot study. AB - BACKGROUND: Developing alternative exercise programmes that can alleviate certain barriers to exercise such as psychological, environmental or socio-economical barriers, but provide similar physiological benefits e.g. increases in muscle mass and strength, is of grave importance. This pilot study aimed to assess the efficacy of an unsupervised, 4-week, whole-body home-based exercise training (HBET) programme, incorporated into daily living activities, on skeletal muscle mass, power and strength. METHODS: Twelve healthy older volunteers (63+/-3 years, 7 men: 5 women, BMI: 29+/-1 kg/m2) carried out the 4-week "lifestyle-integrated" HBET of 8 exercises, 3x12 repetitions each, every day. Before and after HBET, a number of physical function tests were carried out: unilateral leg extension 1-RM (one- repetition maximum), MVC (maximal voluntary contraction) leg extension, lower leg muscle power (via Nottingham Power Rig), handgrip strength and SPPBT (short physical performance battery test). A D 3-Creatine method was used for assessment of whole-body skeletal muscle mass, and ultrasound was used to measure the quadriceps cross-sectional area (CSA) and vastus lateralis muscle thickness. RESULTS: Four weeks HBET elicited significant (p<0.05) improvements in leg muscle power (276.7+/-38.5 vs. 323.4+/-43.4 W), maximal voluntary contraction (60 degrees : 154.2+/-18.4 vs. 168.8+/-15.2 Nm, 90 degrees : 152.1+/-10.5 vs. 159.1+/ 11.4 Nm) and quadriceps CSA (57.5+/-5.4 vs. 59.0+/-5.3 cm 2), with a trend for an increase in leg strength (1-RM: 45.7+/-5.9 vs. 49.6+/-6.0 kg, P=0.08). This was despite there being no significant differences in whole-body skeletal muscle mass, as assessed via D 3-Creatine. CONCLUSIONS: This study demonstrates that increases in multiple aspects of muscle function can be achieved in older adults with just 4-weeks of "lifestyle-integrated" HBET, with a cost-effective means. This training mode may prove to be a beneficial alternative for maintaining and/or improving muscle mass and function in older adults. PMID- 29167735 TI - A review of data sharing statements in observational studies published in the BMJ: A cross-sectional study. AB - In order to understand the current state of data sharing in observational research studies, we reviewed data sharing statements of observational studies published in a general medical journal, the British Medical Journal. We found that the majority (63%) of observational studies published between 2015 and 2017 included a statement that implied that data used in the study could not be shared. If the findings of our exploratory study are confirmed, room for improvement in the sharing of real-world or observational research data exists. PMID- 29177045 TI - Correlation of Carbon Dots' Light-Activated Antimicrobial Activities and Fluorescence Quantum Yield. AB - This study investigated the photo-activated antibacterial function of a series of specifically prepared carbon dots with 2,2'-(ethylenedioxy)bis(ethylamine) as the surface functionalization molecule (EDA-CDots), whose fluorescence quantum yields (PhiF) ranged from 7.5% to 27%. The results revealed that the effectiveness of CDots' photo-activated bactericidal function was correlated with their observed PhiF values. The antimicrobial activities of these EDA-CDots against both Gram negative and Gram positive model bacterial species (E. coli and Bacillus subtilis, respectively) were also evaluated under conditions of varying other experimental parameters including dot concentrations and treatment times. Optimization of the bactericidal effect of the EDA-CDots by a combination of the selected PhiF, concentration and treatment time was explored, and mechanistic implications of the results are discussed. PMID- 29177047 TI - Virucidal efficacy of peracetic acid for instrument disinfection. AB - Background: Various peracetic-acid (PAA)-based products for processing flexible endoscopes on the market are often based on a two-component system including a cleaning step before the addition of PAA as disinfectant. The peracetic acid concentrations in these formulations from different manufacturers are ranging from 400 to 1500 ppm (part per million). These products are used at temperatures between 20 degrees C and 37 degrees C. Since information on the virus inactivating properties of peracetic acid at different concentrations and temperature is missing, it was the aim of the study to evaluate peracetic acid solutions against test viruses using the quantitative suspension test, EN 14476. In addition, further studies were performed with the recently established European pre norm (prEN 17111:2017) describing a carrier assay for simulating practical conditions using frosted glass. Methods: In the first step of examination, different PAA solutions between 400 and 1500 ppm were tested at 20 degrees C, 25 degrees C, and 35 degrees C with three test viruses (adenovirus, murine norovirus and poliovirus) necessary for creating a virucidal action according to the European Norm, EN 14476. A second step for simulating practical conditions based on prEN 17111:2017 followed by spreading a test virus together with soil load onto a glass carrier which was immerged into a peracetic acid solution. A fixed exposure time of five minutes was used in all experiments. Results: In the quantitative suspension test 1500 ppm PAA solution was needed at 35 degrees C for five minutes for the inactivation of poliovirus, whereas only 400 ppm at 20 degrees C for adeno- and murine norovirus were necessary. In the carrier assay 400 ppm peracetic acid at 20 degrees C were sufficient for adenovirus inactivation, whereas 600 ppm PAA were needed at 25 degrees C and 35 degrees C and 1000 ppm at 20 degrees C for murine norovirus. A PAA solution with 1000 ppm at 35 degrees C was required for complete inactivation of poliovirus. However, a dramatically decrease of titer after the drying and immerging could be observed. In consequence, a four log reduction of poliovirus titer could not be achieved in the carrier test. Conclusion: In summary, 1500 ppm PAA at 35 degrees C was necessary for a virucidal action in the quantitative suspension test. After passing the requirements of the suspension test, additional examinations with adeno- and murine norovirus on glass carriers based on prEN 17111:2017 will not additionally contribute to the final claim of an instrument disinfectant for virucidal efficacy. This is due to the great stability of poliovirus in the preceded quantitative suspension test and the fact that poliovirus could not serve as test virus in the following carrier assay. PMID- 29177046 TI - The Gene Ontology of eukaryotic cilia and flagella. AB - Background: Recent research into ciliary structure and function provides important insights into inherited diseases termed ciliopathies and other cilia related disorders. This wealth of knowledge needs to be translated into a computational representation to be fully exploitable by the research community. To this end, members of the Gene Ontology (GO) and SYSCILIA Consortia have worked together to improve representation of ciliary substructures and processes in GO. Methods: Members of the SYSCILIA and Gene Ontology Consortia suggested additions and changes to GO, to reflect new knowledge in the field. The project initially aimed to improve coverage of ciliary parts, and was then broadened to cilia related biological processes. Discussions were documented in a public tracker. We engaged the broader cilia community via direct consultation and by referring to the literature. Ontology updates were implemented via ontology editing tools. Results: So far, we have created or modified 127 GO terms representing parts and processes related to eukaryotic cilia/flagella or prokaryotic flagella. A growing number of biological pathways are known to involve cilia, and we continue to incorporate this knowledge in GO. The resulting expansion in GO allows more precise representation of experimentally derived knowledge, and SYSCILIA and GO biocurators have created 199 annotations to 50 human ciliary proteins. The revised ontology was also used to curate mouse proteins in a collaborative project. The revised GO and annotations, used in comparative 'before and after' analyses of representative ciliary datasets, improve enrichment results significantly. Conclusions: Our work has resulted in a broader and deeper coverage of ciliary composition and function. These improvements in ontology and protein annotation will benefit all users of GO enrichment analysis tools, as well as the ciliary research community, in areas ranging from microscopy image annotation to interpretation of high-throughput studies. We welcome feedback to further enhance the representation of cilia biology in GO. PMID- 29177048 TI - Impact of single room design on the spread of multi-drug resistant bacteria in an intensive care unit. AB - Background: Cross-transmission of nosocomial pathogens occurs frequently in intensive care units (ICU). The aim of this study was to investigate whether the introduction of a single room policy resulted in a decrease in transmission of multidrug-resistant (MDR) bacteria in an ICU. Methods: We performed a retrospective study covering two periods: between January 2002 and April 2009 (old-ICU) and between May 2009 and March 2013 (new-ICU, single-room). These periods were compared with respect to the occurrence of representative MDR Gram negative bacteria. Routine microbiological screening, was performed on all patients on admission to the ICU and then twice a week. Multi-drug resistance was defined according to a national guideline. The first isolates per patient that met the MDR-criteria, detected during the ICU admission were included in the analysis. To investigate the clonality, isolates were genotyped by DiversiLab (bioMerieux, France) or Amplified Fragment Length Polymorphism (AFLP). To guarantee the comparability of the two periods, the 'before' and 'after' periods were chosen such that they were approximately identical with respect to the following factors: number of admissions, number of beds, bed occupancy rate, per year and month. Results: Despite infection prevention efforts, high prevalence of MRD bacteria continue to occur in the original facility. A marked and sustained decrease in the prevalence of MDR-GN bacteria was observed after the migration to the new ICU, while there appear to be no significant changes in the other variables including bed occupancy and numbers of patient admissions. Conclusion: Single room ICU design contributes significantly to the reduction of cross transmission of MRD-bacteria. PMID- 29177049 TI - A 10-year follow-up study of completers versus dropouts following treatment with an integrated cognitive-behavioral group therapy for eating disorders. AB - Background: Cognitive-behavioral therapy (CBT) has been recommended for the treatment of eating disorders, and group therapy is known to have certain advantages over individual therapy. The aim of the current study was to compare the 10-year prognosis of patients who completed integrated group CBT with those who dropped out and to examine the effect of completion of group CBT on the prognosis. Methods: The participants were 65 adult patients with eating disorders. All patients were women and Japanese. The average age (19-37) of the patients was 25.1 +/- 3.8 years, and the average body mass index (BMI) was 17.7 +/- 2.0. We conducted integrated group CBT with the patients and compared eating disorder symptoms, mood states, coping styles, and self-esteem before and after therapy. Furthermore, we compared clinical features and the 10-year prognosis of patients who completed the treatment and those who dropped out. Results: After 10 sessions of group therapy, Eating Attitudes Test scores, Profile of Mood States depression scores, and Coping Inventory for Stressful Situations emotion-oriented scores decreased, while Rosenberg's Self-Esteem Scale scores increased. Regarding the results of the 10-year follow up, the completer group had more patients with a good prognosis. In contrast, the dropout group had more patients with a poor prognosis. Conclusions: Those who completed the integrated group CBT had a good prognosis. Group therapy gives the patients an opportunity to form peer relationships, and helps them to develop communication and socialization skills. Furthermore, in the group therapy sessions, the patients develop self-awareness by listening to other members of the group and they also develop interpersonal relationships. This effect may be temporary, but experience of group therapy may provide hope for the patient and increase the chance of the patient continuing treatment.

PMID- 29177050 TI - Effect of regular exercise training on changes in HbA1c, BMI and VO2max among patients with type 2 diabetes mellitus: an 8-year trial. AB - Objective: The effects of regular exercise on the health promotion of patients with type 2 diabetes mellitus (T2DM) have been well documented. The present study investigated the long-term effects of regular exercise training on biological indicators among these patients. Methods: In this quasi-experimental trial with pretest-post-test design, 65 patients with T2DM aged 33-69 years (experiment (35), control (30)) participated. After 8 years of conducting the program, the data on 30 patients (experiment (15), control (15)) were entered into analysis. The training program included aerobic exercise three sessions per week, 90 min, 50%-80% VO2max. Before and after the intervention, the biological indicators (hemoglobin A1c (HbA1c), body mass index (BMI) and VO2max) were measured. Data were analyzed using multivariate analysis of covariance. Results: Our long-term exercise training program had a significant effect on HbA1C, BMI and Vo2max (P<0.05). Compared with patients in the control group, HbA1c was significantly reduced and BMI and VO2max were significantly improved among the experiment group. Conclusions: Long-term regular physical activity training was found to be helpful in improving glycemic control, body composition and cardiovascular fitness among patients with T2DM. Long-term continuous physical activity offsets the deteriorations of biological indicators found in the control group. Further research, with a particular focus on practical and real-world programming, is needed to determine the responsive health outcomes of such long-term programs on the patients. PMID- 29177051 TI - Type 2 diabetes in general practice in Norway 2005-2014: moderate improvements in risk factor control but still major gaps in complication screening. AB - Objective: To assess the status of type 2 diabetes care in general practice and changes in the quality of care between 2005 and 2014, and to identify areas of diabetes care requiring improvement. Research design and methods: Two cross sectional surveys were performed that included patients with type 2 diabetes in selected areas (n=9464 in 2014, n=5463 in 2005). Quality of care was assessed based on key recommendations in national guidelines. Differences in clinical performance between 2005 and 2014 were assessed in regression models adjusting for age, sex, counties and clustering within general practices. Results: Treatment targets were achieved in a higher proportion of patients in 2014 compared with 2005: hemoglobin A1c <=7.0% (<=53 mmol/mol) in 62.8% vs 54.3%, blood pressure <=135/80 mm Hg in 44.9% vs 36.6%, and total cholesterol <=4.5 mmol/L in 49.9% vs 33.5% (all adjusted P<=0.001). Regarding screening procedures for microvascular complications, fewer patients had recorded an eye examination (61.0% vs 71.5%, adjusted P<0.001), whereas more patients underwent monofilament test (25.9% vs 18.7%, adjusted P<0.001). Testing for albuminuria remained low (30.3%) in 2014. A still high percentage were current smokers (22.7%). Conclusions: We found moderate improvements in risk factor control for patients with type 2 diabetes in general practice during the last decade, which are similar to improvements reported in other countries. We report major gaps in the performance of recommended screening procedures to detect microvascular complications. The proportion of daily smokers remains high. We suggest incentives to promote further improvements in diabetes care in Norway. PMID- 29177052 TI - Biomarkers of tubulointerstitial damage and function in type 1 diabetes. AB - Objective: To evaluate biomarkers of renal tubulointerstitial damage and function in type 1 diabetes with and without diabetic kidney disease. Research design and methods: Cross-sectional case-control study of Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study participants. Cases (N=43) had incident persistent estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 with urinary albumin excretion >300 mg/24 hour. Controls (N=43) had persistent eGFR >90 mL/min/1.73 m2 and urinary albumin excretion <30 mg/24 hour. Urinary and plasma biomarkers reflecting tubular injury, inflammation, fibrosis, secretion, and synthetic function were measured from stored specimens collected at the first study visit with reduced eGFR (for case participants) or the corresponding study year (for control participants). Results: Mean (SD) age was 51 (9) and 50 (8) years for case and control participants, and mean (SD) duration of diabetes was 30 (6) and 30 (5) years, respectively. Mean (SD) eGFR was 39 (14) and 103 (9) mL/min/1.73 m2 for case and control participants, and mean (SD) albumin excretion rate was 1978 (2914) and 10 (7) mg/day, respectively. Comparing cases with controls, significant differences were observed in each measured biomarker, including urine epidermal growth factor (mean 5.3 vs 21.2 MUg/g creatinine for case vs control participants, respectively), urine monocyte chemoattractant protein-1 (596 vs 123 ng/g creatinine), urine galectin-3 (168 vs 52 MUg/g creatinine), plasma soluble tubular necrosis factor receptor-1 (3695 vs 1022 pg/mL), plasma galectin-3 (21.3 vs 11.0 ng/mL), urinary clearances of hippurate (70 vs 167 mL/min) and cinnamoylglycine (77 vs 317 mL/min), and plasma arginine-citrulline ratio (5.6 vs 7.7 MUg/MUg), each P<0.001. Conclusions: Marked abnormalities in biomarkers of kidney tubular injury, inflammation, fibrosis, secretion, and synthetic function accompany reduced eGFR and albuminuria in type 1 diabetes.

AB - Objective: To evaluate the efficacy and safety of a new, single-administration Otic Solution containing florfenicol, terbinafine and mometasone furoate for the treatment of canine otitis externa (OE). Design: The clinical efficacy and safety study was a multicentre, controlled, masked and randomised field study conducted over 30 days. Two hundred and twenty-one (221) client-owned dogs of varying breeds with diagnosed bacterial and/or fungal OE were enrolled. Procedure: Dogs were randomised to either Otic Solution or control groups. Evaluations were conducted over a minimum period of 30 days with a primary effectiveness endpoint based on the improvement in a clinical severity score at the final visit (day 30). Safety analyses were based on clinical and laboratory parameters and the occurrence of adverse events. Results: The Otic Solution group demonstrated a significantly higher treatment success rate compared with that observed for the control group (72.5 per cent v 11.1 per cent, P value=0.0001) for cases of OE caused by Staphylococcus pseudintermedius and Malassezia pachydermatis. No significant safety findings were reported. Conclusions/clinical relevance: This new ototopical formulation provides safe and effective treatment of canine OE and is an important alternative antimicrobial for this indication. The single administration dosage regimen eliminates opportunities for client dosage administration errors and medication stockpiling. PMID- 29177054 TI - Increase in branched-chain amino acids due to acidemia in neonatal calves with diarrhoea. AB - The aim of this study was to investigate the relationships between acid-base status and plasma branched-chain amino acids (BCAA) concentration in calves with diarrhoea for intravenous nutrition, especially with amino acid solution in calves with diarrhoea. Thirty-four Holstein calves aged 11.0+/-5.9 days old were enrolled in this study. In 10 of 34 calves exhibiting clinical signs of diarrhoea, severe dehydration and acidemia were observed (severe group: pH: 7.04+/-0.11, base excess (BE): -17.4+/-4.5) based on blood gas analysis. In 7 of 34 calves exhibiting clinical signs of diarrhoea, mild dehydration and acidemia were observed (mild group: pH: 7.29+/-0.06, BE: 0.0+/-5.2). The other 17 calves did not exhibit dehydration or acidemia (pH: 7.41+/-0.02, BE: 11.2+/-3.5) based on clinical signs and blood gas analysis. The plasma concentration of BCAA was significantly higher in the severe group than in the other groups. In addition, the blood pH and plasma concentrations of BCAA (r=-0.41, P<0.05) were significantly and negatively correlated. As calves with metabolic acidosis have increased plasma BCAA concentrations due to hypermetabolic states of proteolysis, amino acid solutions containing low concentrations of BCAA may be useful to gradually correct the negative nitrogen balance. PMID- 29177055 TI - Population characteristics of golden retriever lifetime study enrollees. AB - Background: Studying cancer and other diseases poses a problem due to their protracted and multifactorial nature. Prospective studies are useful to investigate chronic disease processes since collection of lifestyle information, exposure data and co-incident health issues are collected before the condition manifests. The Golden Retriever Lifetime Study is one of the first prospective studies following privately-owned dogs throughout life to investigate the incidence and risk factors for disease outcomes, especially cancer.Owners of golden retrievers in the contiguous United States volunteered their dogs in early life. Owners and veterinarians complete online questionnaires about health status and lifestyle; dogs undergo a physical examination and collection of biological samples annually. The data presented summarize the initial study visits and the corresponding questionnaires for 3044 dogs in the cohort. Results: The median age of dogs at enrollment was 14.0 months (interquartile range (IQR): 8-20 months). Approximately half of the population had undergone gonadectomy by their initial study visit. Medical conditions reported at enrollment consisted primarily of integumentary, gastrointestinal and urinary dysfunction. A large majority of the dogs have a record of having received preventive care (vaccines, parasiticides, flea and heartworm prevention) by the time of the initial study visit. Clinical pathology data were unremarkable. Conclusions: This study represents one of the first lifetime observational investigations in veterinary medicine. The population characteristics reported here indicate a healthy cohort of golden retrievers cared for by owners committed to their dogs' health. Data acquired over the study period will provide valuable information about genetic, dietary and environmental risk factors associated with disease in golden retrievers and a framework for future prospective studies in veterinary medicine. PMID- 29177056 TI - Physical activity and central adiposity in a cohort of African-American adults. AB - Background: Visceral adipose tissue (VAT) is known as an independent predictor of cardiometabolic risk and all-cause mortality, while increased physical activity has been shown to improve cardiometabolic risk. The purpose of the present study was to determine whether or not there is an association between objectively measured physical activity and VAT in a community-based cohort of African American adults, a population at higher-than-average risk for cardiometabolic diseases. Methods: Free-living physical activity was quantified using accelerometry while VAT and abdominal subcutaneous fat were estimated using dual x-ray absorptiometry in a cohort of African Americans, ages 30-50 years, enrolled in the Modeling the Epidemiologic Transition Study. Univariate and multivariate analyses were used to determine the degree of association comparing moderate-to vigorous physical activity (MVPA), vigorous activity, and sedentary behavior with measures of central adiposity including VAT, subcutaneous fat, and waist circumference. Results: A total of 271 individuals with complete data were included in the analyses. Women, on average, had significantly more VAT and abdominal subcutaneous fat than men. There were statistically significant inverse univariate correlations between MVPA and measures of abdominal adiposity (-0.30, p < 0.001) and activity counts and adiposity (-0.31, p < 0.001) among both sexes. These significant associations remained after controlling for age, sex, and smoking status; neither alcohol consumption nor employment status were associated with abdominal adiposity. Time in sedentary behavior was not meaningfully associated with central adiposity in either sex (women: -0.02, p = 0.79; men: 0.21, p = 0.04). Conclusions: To our knowledge, this study is the first to identify significant inverse associations between MVPA and measures of central adiposity among African American adults from a community-based cohort using an objective measure of physical activity and a validated quantitative imaging technique. PMID- 29177057 TI - Motivation and perceived competence for healthy eating and exercise among overweight/obese adolescents in comparison to normal weight adolescents. AB - Background: The current literature on determinants of behavior change in weight management lacks sufficient studies on type of motivation among children/adolescents, on perceived competence, and in relation to healthy eating. This study aimed to investigate type of motivation and levels of perceived competence for healthy diet and exercise, as well as general self efficacy among adolescents. We hypothesized that overweight/obese adolescents would demonstrate lower autonomous motivation and perceived competence regarding diet and exercise, and lower self-efficacy in general, and that the scores would be influenced by socioeconomic factors. Methods: Normal weight (n = 40, body mass index < 85% for age and gender) and overweight or obese adolescents (n = 60, body mass index >= 85% for age and gender) aged 13-18 years were recruited from pediatric ambulatory clinics. Information was collected about demographics, socioeconomic factors, and lifestyle behaviors. The study subjects completed a survey including the Treatment Self-Regulation Questionnaire (TSRQ) and the Perceived Competence Scale (PCS) for healthy eating and exercise, and the General Self-Efficacy Scale (GSES). Composite scores for the three scales were compared between the two groups using the using the two-sample t-test (for normal data) or the Mann Whitney U test (for non-parametric data). Relationships between the composite scores and patient characteristics were determined using Pearson or Spearman's correlations. Results: The average age of the total cohort was 15.9 +/- 1.9 years. 54% were female, and 82% identified as Latino/Hispanic. In comparison to normal weight subjects, overweight/obese adolescents exhibited higher scores for controlled motivation (mean +/- standard deviation 28.3 +/- 9.3 vs 18.1 +/- 8.1) and higher perceived competence [median and 25-75% interquartile range 22.5 (19.0 26.0) vs 20.0 (15.5-25.0)] in relation to eating a healthy diet. These differences persisted after adjustment for age, sex, paternal education, and family income. Conclusions: Overweight/obese adolescents did not lack autonomous motivation but demonstrated higher controlled motivation and perceived competence for healthy eating in comparison to normal weight adolescents, independent of socioeconomic factors. In the clinical practice of weight management, providers should carefully assess adolescents for type of motivation and perceived competence, while accounting for potential barriers to behavior change. PMID- 29177058 TI - Biomarkers of cardiovascular stress and fibrosis in preclinical hypertrophic cardiomyopathy. AB - Objective: Sarcomeric gene mutation carriers without overt left ventricular hypertrophy (G+/LVH-) can harbour subclinical changes in cardiovascular structure and function that precede the development of hypertrophic cardiomyopathy (HCM). We sought to investigate if circulating biomarkers of cardiovascular stress and collagen metabolism among G+/LVH- individuals, measured at rest and following exercise provocation, yield further insights into the underlying biology of HCM. Methods: We studied 76 individuals with overt HCM, 50 G+/LVH- individuals and 41 genotype-negative related controls enrolled in a cross-sectional, multicentre observational study (HCMNet). Biomarkers of cardiac stress (N-terminal pro-B-type natriuretic peptide, NT-proBNP; high-sensitivity troponin I, hsTnI; soluble ST2) and fibrosis (carboxy-terminal propeptide of procollagen type I; C-terminal telopeptide of type I collagen; galectin-3; periostin) were measured. Results: Individuals with overt HCM had elevated NT-proBNP and hsTnI compared with G+/LVH- subjects and controls at rest, along with an exaggerated increase in NT-proBNP and hsTnI in response to exercise. We found no detectable differences in resting or exercise-provoked biomarker profiles of cardiovascular stress and fibrosis among G+/LVH- individuals compared with healthy controls despite subtle echocardiographic differences in cardiac structure and function. Conclusion: Dynamic exercise testing exaggerated resting differences in natriuretic peptides and troponin elevations among individuals with overt HCM. In contrast, we found no differences in biomarker profiles of cardiovascular stress and fibrosis among G+/LVH- individuals compared with controls even after maximal exercise provocation. Our findings highlight the need for continued investigation into early phenotypes of sarcomeric gene mutations and the evolution of HCM. PMID- 29177059 TI - Gender differences in the decrease of in-hospital mortality in patients with acute myocardial infarction during the last 20 years in Switzerland. AB - Objective: To assess temporal trends of in-hospital mortality in patients with acute myocardial infarction (AMI) enrolled in the Swiss nationwide registry (AMIS Plus) over the last 20 years with regard to gender, age and in-hospital treatment. Methods: All patients with AMI from 1997 to 2016 were stratified according to ST-segment elevation myocardial infarction (STEMI) or non-STEMI (NSTEMI), and gender using logistic regression analyses. Results: Among 51 725 patients, 30 398 (59%) had STEMI and 21 327 (41%) had NSTEMI; 73% were men (63.9+/-12.8 years) and 27% were women (71.7+/-12.5 years). Over 20 years, crude in-hospital STEMI mortality decreased from 9.8% to 5.5% in men and from 18.3% to 6.9% in women. In patients with NSTEMI, it decreased from 7.1% to 2.1% in men and from 11.0% to 3.6% in women. After adjustment for age, mortality decreased per additional admission year by 3% in men with STEMI (OR 0.97, 95% CI 0.96 to 0.98, P<0.001), by 5% in women with STEMI (OR 0.95, 95% CI 0.93 to 0.96, P<0.001), by 6% in men with NSTEMI (OR 0.94, 95% CI 0.93 to 0.96, P<0.001) and by 5% in women with NSTEMI (OR 0.95, 95% CI 0.93 to 0.97, P<0.001). In patients <60 years, a decrease in mortality was seen in women with STEMI (OR 0.94, 95% CI 0.90 to 0.99, P=0.025) and NSTEMI (OR 0.87, 95% CI 0.80 to 0.94, P<0.001) but not in men with STEMI (OR 1.01, 95% CI 0.98 to 1.04, P=0.46) and NSTEMI (OR 0.98, 95% CI 0.94 to 1.03, P=0.41). The mortality decrease in patients with AMI was closely associated with the increase in reperfusion therapy. Conclusion: From 1997 to 2016, in hospital mortality of patients with AMI in Switzerland has halved and was more pronounced in women, particularly in the age category <60 years. Trial registration number: NCT01305785; Results. PMID- 29177060 TI - Predictors of incident proteinuria among patients with SLE. AB - Objective: To identify fixed and time-varying predictors of incident proteinuria. Methods: This analysis was based on patients who did not have a history of diabetes and who did not have a prior episode of renal involvement. We defined an incident case of proteinuria as two or more measures of urine protein to creatinine ratio (or 24-hour protein measure) greater than 0.5 in two visits separated by more than 30 days and less than 180 days. We estimated rates of incident proteinuria in subgroups of patients with lupus defined by time invariant and time-varying predictors. Results: Among 895 patients included in the analysis, 840 (94%) were female, and 518 (58%) were Caucasian, 304 (34%) African-American, with mean age of 42 years at the start of follow-up. We observed 57 incident cases of proteinuria over a span of 4669 person-years of cohort follow-up. The overall rate of incident proteinuria was 12.2 per 1000 person-years. The rate was significantly lower among those of older age, and higher among those who were not Caucasian. In those with a very low C3 measure in a previous cohort visit, the rate was increased by a factor of 16.1 and in those with a very low C4 by 16.3. The rate among those prescribed hydroxychloroquine or ACE inhibitors/ARB was similar to those not on them. Conclusions: Older patients with SLE are at low risk for developing proteinuria. There was not strong evidence that hydroxychloroquine or angiotensin-converting-enzyme (ACE) inhibitor reduced the risk of proteinuria. The highest rates of incident proteinuria were among those with recent low complement. PMID- 29177061 TI - Illness representations of systemic lupus erythematosus and systemic sclerosis: a comparison of patients, their rheumatologists and their general practitioners. AB - Objective: Discrepancies in illness representations between patients and physicians result in treatment difficulties, decreased well-being of patients and misunderstandings and disrupted communication. Hence, the objective of this study was to compare illness perceptions of individual patients with systemic lupus erythematosus (SLE) and systemic sclerosis (SSc), their rheumatologists and their general practitioners (GPs) and explore potential differences. Methods: This study has a cross-sectional design. Patients with SLE and SSc, who were followed at the rheumatology department of the University Hospitals Leuven (Belgium), completed the revised Illness Perception Questionnaire which measures patients' perceptions of their condition and captures nine dimensions. Physicians completed the Revised Illness Perception Questionnaire for Healthcare Professionals which consists of seven dimensions and measures perceptions of the healthcare professional regarding the disease of their patients. Intraclass correlation was performed to examine relationships between pairs of respondents; Cohen's d was used for estimating the magnitude of the difference. Results: Questionnaires were sent to 284 patients of whom 241 (113 SSc and 128 SLE patients) were included. Five rheumatologists and 160 GPs participated. For both diseases, positive correlations were found for 'consequences', 'illness coherence' and 'emotional representations' among patients, rheumatologists and GPs. GPs scored higher on the 'consequences' of these diseases for the patient (d=0.71 for SLE; d=0.80 for SSc). Differences between rheumatologists and GPs were small for SSc and moderate to large for 'consequences' (d=0.56) and 'timeline acute/chronic' (d=0.95) in SLE with higher scores for GPs. Conclusions: For both diseases and among the three groups, significant correlations are detected for the dimensions 'consequences', 'illness coherence' and 'emotional representations'. Differences between rheumatologists and GPs were mainly detected in the case of SLE patients. This can have implications for the collaboration between these two groups of physicians in daily clinical practice. Clinical trial registration: NCT02655640; Pre-results. PMID- 29177062 TI - Validity of studies suggesting postsurgical chemotherapy for resectable gastric cancer: critical appraisal of randomised trials. AB - Background and aim: In 2013, Diaz-Nieto et al published a Cochrane review to summarise the impact of postsurgical chemotherapy versus surgery alone on survival for resectable gastric cancer. The authors concluded that postsurgical chemotherapy showed an improvement in overall survival. The aim of this article was to assess the validity of four studies included in the Cochrane review and to investigate the impact of an exclusion of these four studies on the result of the meta-analysis. Methods: Overall survival was selected as endpoint of interest. Among the 34 included papers which analysed this endpoint, we identified the four publications which have the highest weights to influence the final result. The validity of these papers was analysed using the CONSORT (Consolidated Standards of Reporting Trials) checklist for randomised controlled trials. We performed a new meta-analysis without the four studies in order to assess their impact on the general result of the original meta-analysis. Results: The analysed four studies revealed several inconsistencies: inappropriate answers were found in up to 77% of the items of the CONSORT checklist. Unclear or inadequate randomisation, missing blinded set-up, conflict of interest and lacking intention-to-treat analysis were the most common findings. When performing a meta-analysis excluding the four criticised studies, postsurgical chemotherapy still showed a significant improvement in overall survival. Even when excluding all single studies with a statistically significant outcome by themselves and performing a meta-analysis on the remaining 26 studies, the result remains statistically significant. Conclusion: The four most powerful publications in the Cochrane review show substantial deficits. We suggest a more critical appraisal regarding the validity of single studies. However, after the exclusion of these four studies, the result of the meta-analysis did not change. PMID- 29177063 TI - Circulating microRNAs as potential biomarkers to detect transformation of Barrett's oesophagus to oesophageal adenocarcinoma. AB - Objective: Circulating microRNAs (miRNAs) are promising biomarkers for the early detection of cancers. This study aimed to address potential circulating miRNAs to monitor the progression from Barrett's oesophagus (BO) to oesophageal adenocarcinoma (OAC). Design: We comprehensively analysed tissue and serum miRNA expression profiles of BO mice model (L2-interleukin-1beta (IL-1beta) mice) using microarray analysis. To validate the data from mice, a published dataset of human plasma miRNAs, consisting of eight patients with OAC, eight with BO and six healthy controls, was used (GSE51410). Results: We identified 20 upregulated miRNAs and 44 downregulated miRNAs both in tissues and in sera of 46-week-old mice compared with 28-week-old mice. Two of the 20 miRNAs (miR-128-3 p and miR 328-3 p) were upregulated, and five of the 44 miRNAs (miR-143-3 p, miR-144-3 p, miR-15a-5p, miR-1-3 p and miR-133b) were downregulated in plasma of patients with OAC compared with plasma of patients with BO. Receiver operating characteristic curve analysis revealed that a prediction index calculated by the above-mentioned seven miRNAs could discriminate between patients with OAC and those without OAC with the area under the curve of 0.91, sensitivity of 1 and specificity of 0.75. Conclusions: Levels of the seven circulating miRNAs may represent the tissue miRNA levels and could be promising non-invasive biomarkers to evaluate the carcinogenic process of BO. PMID- 29177064 TI - Efficacy of capsule endoscopy in patients with cirrhosis for the diagnosis of upper gastrointestinal lesions and small bowel abnormalities: a study protocol for prospective interventional study. AB - Introduction and aims: The role of capsule endoscopy (CE) in patients with liver cirrhosis (LC) has yet to be established; however, it is likely that it will remain a valuable diagnostic modality in several groups of patients with LC. The primary aims of the current prospective interventional study are to examine the prevalence for small bowel lesions and transit time of CE in the gastrointestinal tract in patients with LC with oesophageal varices (EVs) requiring endoscopic therapies. Methods and analysis: The current study will be a single-centre prospective interventional study. Our study participants are LC subjects with portal hypertension who were determined to be necessary for prophylactic endoscopic therapies for EVs. From the view point of safety, patients with gastrointestinal obstruction or fistula or those being suspected of having gastrointestinal obstruction or fistula will be excluded from our study. Patients with implanted medical devices will be also excluded. CE will be performed prior to prophylactic endoscopic therapies in the same hospitalisation and relevant images will be analysed after 8 hours by expert endoscopists. This study will continue to recruit until 50 participants. Ethics and dissemination: This study has received approval from the Institutional Review Board at Hyogo College of Medicine (approval no. 2680). The study protocol, informed assent form and other submitted files were reviewed and acknowledged. Final data will be publicly scattered regardless of the study results. A report releasing study results will be submitted for publication in a suitable journal after being finished in data collection. Trial registration number: UMIN000028433 (https://upload.umin.ac.jp/). PMID- 29177065 TI - Patients with symptoms of delayed gastric emptying have a high prevalence of oesophageal dysmotility, irrespective of scintigraphic evidence of gastroparesis. AB - Background: Patients with symptoms suggestive of gastroparesis exhibit several symptoms, such as epigastric pain, postprandial fullness, bloating and regurgitation. It is uncertain if such symptoms reflect underlying oesophageal motor disorder. Aims: To examine whether patients with epigastric pain and postprandial distress syndrome suggestive of functional dyspepsia and/or gastroparesis also have concomitant oesophageal motility abnormalities and, if so, whether there are any associations between these disturbances. Methods: In this retrospective cohort study, consecutive patients with functional gastrointestinal symptoms suggestive of gastric neuromuscular dysfunction (gastroparesis or functional dyspepsia) underwent clinical assessment, gastric scintigraphy, oesophageal high-resolution manometry and ambulatory pH monitoring using standard protocols. Results: We studied 61 patients with various functional upper gastrointestinal symptoms who underwent gastric scintigraphy, oesophageal high-resolution manometry and ambulatory pH monitoring. Forty-four patients exhibited gastroparesis by gastric scintigraphy. Oesophageal motility disorders were found in 68% and 42% of patients with or without scintigraphic evidence of gastroparesis respectively, suggesting of overlapping gastric and oesophageal neuromuscular disorder. Forty-three per cent of patients with gastroparesis had abnormal oesophageal acid exposure with mean % pH <4.0 of 7.5 in contrast to 38% of those symptomatic controls with normal gastric emptying, with mean %pH <4.0 of 5.4 (NS). Symptoms of epigastric pain, heartburn/regurgitation, bloating, nausea, vomiting, dysphagia, belching and weight loss could not distinguish patients with or without gastroparesis, although weight loss was significantly more prevalent and severe (p<0.002) in patients with gastroparesis. There was no relationship between oesophageal symptoms and motor or pH abnormalities in either groups. Conclusions: Irrespective of gastric emptying delay by scintigraphy, patients with symptoms suggestive of gastric neuromuscular dysfunction have a high prevalence of oesophageal motor disorder and pathological oesophageal acid exposure that may contribute to their symptoms and may require therapy. High resolution oesophageal manometry and pH monitoring are non-invasive and potentially useful in the assessment and management of these patients. PMID- 29177066 TI - Non-acid gastro-oesophageal reflux is associated with squamous cell carcinoma of the oesophagus. AB - Introduction: Squamous cell carcinoma of the oesophagus is a common cancer among South Africans. Due to the absence of effective screening and surveillance programme for early detection and late presentation, squamous cell carcinoma of the oesophagus is usually diagnosed at an advanced stage or when metastasis has already occurred. The 5-year survival is often quoted at 5%-10%, which is poor. Objectives: To determine the association between oesophageal squamous cell carcinoma (OSCC) and non-acid gastro-oesophageal reflux disease. Methods: Study design: A cross-sectional case-control analytical study of patients referred to the Gastroenterology Division of Steve Biko Academic Hospital in Pretoria, South Africa. All patients had combined multichannel impedance and pH studies done and interpreted after upper gastroscopy using the American College of Gastroenterology guidelines by two clinicians. Results: Thirty-two patients with OSCC were recruited: non-acid reflux was found in 23 patients (73%), acid reflux in 2 patients (6%) and 7 patients (22%) had normal multichannel impedance and pH studies.Forty-nine patients matched by age, gender and race were recruited as a control group. Non-acid reflux was found in 11 patients (22%), acid reflux in 31 patients (63%) and 7 patients (14%) had normal multichannel impedance and pH monitoring study. Conclusion: The significance of the association between non acid reflux and OSCC was tested using chi2, and simple logistic regression was used to adjust for the effects of potential confounders.The OR of developing OSCC in patients with non-acid gastro-oesophageal reflux was 8.8 (95% CI 3.2 to 24.5, P<0.0001) in this South African group.Alcohol and smoking had no effect on these results. PMID- 29177067 TI - Joint symptoms associated with anastrozole and letrozole in patients with breast cancer: a retrospective comparative study. AB - Background: Joint symptoms are a common side effect of aromatase inhibitors. However, it is not known if the risk of these symptoms varies between the members of this drug class. The aim of this study was to compare the frequency of joint symptoms associated with anastrozole and that associated with letrozole. Methods: We retrospectively reviewed patients with breast cancer who were treated with anastrozole or letrozole at Tsukiji Breast Clinic, Japan, between April 2008 and July 2014. Joint symptoms were deemed to include both joint pain and painless joint symptoms. The time to onset of joint symptoms in the anastrozole group was compared with that in the letrozole group using Kaplan-Meier curves and the log rank test. Results: Of 141 patients identified to have received aromatase inhibitors, 70 had been treated with anastrozole and 71 with letrozole. Joint symptoms occurred in 60.3% of the 141 patients (60.0% in the anastrozole group and 60.6% in the letrozole group; p = 1). Median time to appearance of joint symptoms was 583 days, with no significant difference between the anastrozole and letrozole groups (p = 0.962). There was no significant difference in time to onset of joint pain (p = 0.139); however, time to onset of painless joint symptoms was significantly shorter in the anastrozole group (p = 0.022). The sites at which joint symptoms occurred were similar in the two groups. Conclusions: The results of this study indicate that there is no difference in the pattern of occurrence of joint symptoms caused by anastrozole and those caused by letrozole. Trial registration: Trial registration was not required for this study because of its retrospective nature and lack of intervention. PMID- 29177068 TI - Carbonate-rich dendrolitic cones: insights into a modern analog for incipient microbialite formation, Little Hot Creek, Long Valley Caldera, California. AB - Ancient putative microbial structures that appear in the rock record commonly serve as evidence of early life on Earth, but the details of their formation remain unclear. The study of modern microbial mat structures can help inform the properties of their ancient counterparts, but modern mineralizing mat systems with morphological similarity to ancient structures are rare. Here, we characterize partially lithified microbial mats containing cm-scale dendrolitic coniform structures from a geothermal pool ("Cone Pool") at Little Hot Creek, California, that if fully lithified, would resemble ancient dendrolitic structures known from the rock record. Light and electron microscopy revealed that the cm-scale 'dendrolitic cones' were comprised of intertwined microbial filaments and grains of calcium carbonate. The degree of mineralization (carbonate content) increased with depth in the dendrolitic cones. Sequencing of 16S rRNA gene libraries revealed that the dendrolitic cone tips were enriched in OTUs most closely related to the genera Phormidium, Leptolyngbya, and Leptospira, whereas mats at the base and adjacent to the dendrolitic cones were enriched in Synechococcus. We hypothesize that the consumption of nutrients during autotrophic and heterotrophic growth may promote movement of microbes along diffusive nutrient gradients, and thus microbialite growth. Hour-glass shaped filamentous structures present in the dendrolitic cones may have formed around photosynthetically-produced oxygen bubbles-suggesting that mineralization occurs rapidly and on timescales of the lifetime of a bubble. The dendrolitic-conical structures in Cone Pool constitute a modern analog of incipient microbialite formation by filamentous microbiota that are morphologically distinct from any structure described previously. Thus, we provide a new model system to address how microbial mats may be preserved over geological timescales. PMID- 29177069 TI - Differences in early risk factors for obesity between African American formula fed infants and White breastfed controls. AB - Background: Previous RCTs to prevent early rapid weight gain were conducted in predominantly White, well-educated, middle-income mother-infants at low risk for obesity. To inform the design of an RCT in a higher-risk sample, we conducted a short-term, longitudinal study to compare maternal feeding beliefs and behaviors, infant sleep, intake, and growth of African American formula feeding (AAFF) dyads to a comparison sample of White breastfeeding (WBF) dyads. We also assessed the feasibility of recruiting and retaining AAFF participants. Methods: AAFF (n = 32) and WBF (n = 25) mother-infants were assessed at 2, 8, and 16 weeks postpartum. Data included demographics and maternal reports of feeding beliefs and behaviors, infant sleep, meal size, and feeding frequency, and measured infant length and weight. Results: AAFF and WBF mothers differed in demographics. AAFF mothers reported greater agreement with pressuring the infant to eat and feeding to soothe a fussy infant. Compared to WBF infants, AAFF infants slept fewer hours and consumed more grams/feeding from 2 to 16 weeks. There were no group differences in feeding frequency, which resulted in AAFF infants consuming more grams/day of milk than WBF infants. AAFF infants had lower gestational age, lower weight at 2 weeks, and had more rapid weight gain from 8 to 16 weeks. Conclusions: Findings point to potentially modifiable risk factors that may underlie disparities in early obesity among AAFF infants, including short sleep duration, feeding beliefs and behaviors, and rapid growth, but also confirm the challenges of recruiting and retaining AAFF participants, all of which inform the design and feasibility of an early preventive intervention. Trial registration: Retrospectively registered in clinicaltrials.gov on August 23, 2016 (2013102510). PMID- 29177070 TI - Evaluation of neurological changes in secondary progressive multiple sclerosis patients treated with immune modulator MIS416: results from a feasibility study. AB - Background: While disease progression can be readily monitored in early stage relapsing multiple sclerosis (MS), it is more challenging for secondary progressive multiple sclerosis (SPMS). This advanced stage of disease has distinct pathophysiology due to compartmentalization of neuroinflammatory activity within the central nervous system, resulting in increased incidence and severity of cognitive dysfunction. The shift in the dominant disease pathways is underscored by the failure of relapsing therapies to benefit SPMS patients, highlighting the need for novel treatment strategies and clinical trial endpoints that are well-aligned with potential benefits. The Expanded Disability Status Scale (EDSS) is widely used but is weighted towards ambulatory ability, lacking sensitivity to other aspects of neurological impairment experienced in more severely disabled SPMS patients, so may not effectively capture their clinical status.To investigate the feasibility of an alternative clinical trial endpoint model for a phase 2B trial of an immune modulator for SPMS, the potential for treatment efficacy-based patient-centered outcomes was assessed within the context of a before and after, 12-week clinical trial of safety and tolerability. Methods: Patients treated with MIS416 for 12 weeks were evaluated for clinical status at baseline and end of dosing, using the established Multiple Sclerosis Functional Composite, Short Form Health Survey, and Expanded Disability Status Scale. Responder status was determined for eight outcome measures based on minimally important change, defined using published studies. To evaluate the patients' immune response to MIS416, blood plasma samples collected at baseline and pre- and 24-h post doses 1-4 were analyzed using multiplex cytokine quantification assays. Results: Using a combination of patient-centered outcomes, MIS416 treatment was associated with improved clinical status for 10/11 patients: eight patients showed improvement on two to five outcome measures, five of which also showed improvement by EDSS. Multi-dimensional scaling analysis of MIS416 induced factors quantified in individual patients, revealed immune response patterns which had a strong concordance with the extent of the patients' clinical response. Conclusions: The data support the feasibility of using patient-centered outcomes as additional clinical trial endpoints, for determining the efficacy of disease-modifying therapies, in secondary progressive multiple sclerosis patients.

AB - Background: Preload studies are used to investigate the satiating effects of foods and food ingredients. However, the design of preload studies is complex, with many methodological considerations influencing appetite responses. The aim of this pilot investigation was to determine acceptability, and optimise methods, for a future satiety preload study. Specifically, we investigated the effects of altering (i) energy intake at a standardised breakfast (gender-specific or non gender specific), and (ii) the duration between mid-morning preload and ad libitum lunch meal, on morning appetite scores and energy intake at lunch. Methods: Participants attended a single study visit. Female participants consumed a 214-kcal breakfast (n = 10) or 266-kcal breakfast (n = 10), equivalent to 10% of recommended daily energy intakes for females and males, respectively. Male participants (n = 20) consumed a 266-kcal breakfast. All participants received a 250-ml orange juice preload 2 h after breakfast. The impact of different study timings was evaluated in male participants, with 10 males following one protocol (protocol 1) and 10 males following another (protocol 2). The duration between preload and ad libitum lunch meal was 2 h (protocol 1) or 2.5 h (protocol 2), with the ad libitum lunch meal provided at 12.00 or 13.00, respectively. All female participants followed protocol 2. Visual analogue scale (VAS) questionnaires were used to assess appetite responses and food/drink palatability. Results: Correlation between male and female appetite scores was higher with the provision of a gender-specific breakfast, compared to non-gender specific breakfast (Pearson correlation of 0.747 and 0.479, respectively). No differences in subjective appetite or ad libitum energy intake were found between protocols 1 and 2. VAS mean ratings of liking, enjoyment, and palatability were all > 66 out of 100 mm for breakfast, preload, and lunch meals. Conclusions: The findings of this pilot study confirm the acceptability of this methodology for future satiety preload studies. Appetite scores increased from preload to ad libitum lunch meal; however, no specific differences were found between protocols. The results highlight the importance of considering energy intake prior to preload provision, with a gender-specific breakfast improving the correlation between male and female appetite score responses to a morning preload. PMID- 29177072 TI - Efficacy of platelet-rich plasma injections for symptomatic tendinopathy: systematic review and meta-analysis of randomised injection-controlled trials. AB - Aim: To determine the efficacy of platelet-rich plasma (PRP) injections for symptomatic tendinopathy. Design: Systematic review of randomised, injection controlled trials with meta-analysis. Data sources: Systematic searches of MEDLINE and EMBASE, supplemented by manual searches. Eligibility criteria for selecting studies: Randomised controlled trials with 3 months minimum follow-up that evaluated pain reduction with PRP versus control (saline, local anaesthetic, corticosteroid) injections in patients with symptomatic tendinopathy. Results: A total of 16 randomised controlled trials (18 groups) of PRP versus control were included. Median sample size was 35 patients, a study size that would require an effect size >=1.0 to achieve statistical significance. PRP was more efficacious than control in reducing tendinopathy pain, with an effect size of 0.47 (95% CI 0.22 to 0.72, p<0.001), signifying a moderate treatment effect. Heterogeneity among studies was moderate (I2=67%, p<0.001). In subgroup analysis and meta regression, studies with a higher proportion of female patients were associated with greater treatment benefits with PRP. Conclusions: Injection of PRP is more efficacious than control injections in patients with symptomatic tendinopathy. PMID- 29177073 TI - The anticipatory stress response to sport competition; a systematic review with meta-analysis of cortisol reactivity. AB - Objective: Athletes anticipating sport competition regularly experience distinct emotional and physiological responses as a result of the expected psychosocial and physical stress. Specifically, cortisol, an indicator of hypothalamic pituitary-adrenal axis activation, prepares the athlete for the psychological and physiological demands of competition. The objective of this meta-analysis is to analyse the magnitude of the anticipatory cortisol response in athletes preparing to participate in sport competition and to examine the influence of gender, level of competition and data collection time. Design: Systematic review with meta analysis. Data sources: Four electronic databases were searched to March 2017: PubMed, PsycINFO, SPORTDiscus and Scopus. Eligibility criteria for selecting studies: (1) Athletes participating in real sport competition;(2) salivary cortisol concentration collected before competition in addition to baseline sample(s);(3) original research article published in English language. Results: Data from 25 studies provided 27 effect sizes. A significant anticipatory cortisol response of g=0.85, p<0.001 was identified. Males had a stronger trend for greater cortisol reactivity (g=1.07) than females (g=0.56, p=0.07). Females and athletes competing at international level did not demonstrate a significant anticipatory stress response. There were no significant differences between level of competition, type of sport or time of competition. Meta-regression indicated that the anticipatory cortisol response is greater when assessed closer to the start of competition (Q=6.85, p=0.009). Summary/conclusion: The anticipatory cortisol response before sport competition reflects moderate cortisol reactivity that prepares athletes optimally for the demands of sport competition via the influence on cognitive processes and attentional control. However, both female athletes and international competitors did not demonstrate a significant anticipatory cortisol response, possibly due to differences in appraisal of the stress of sport competition. PMID- 29177074 TI - Prognostic factors for specific lower extremity and spinal musculoskeletal injuries identified through medical screening and training load monitoring in professional football (soccer): a systematic review. AB - Background: Medical screening and load monitoring procedures are commonly used in professional football to assess factors perceived to be associated with injury. Objectives: To identify prognostic factors (PFs) and models for lower extremity and spinal musculoskeletal injuries in professional/elite football players from medical screening and training load monitoring processes. Methods: The MEDLINE, AMED, EMBASE, CINAHL Plus, SPORTDiscus and PubMed electronic bibliographic databases were searched (from inception to January 2017). Prospective and retrospective cohort studies of lower extremity and spinal musculoskeletal injury incidence in professional/elite football players aged between 16 and 40 years were included. The Quality in Prognostic Studies appraisal tool and the modified Grading of Recommendations Assessment, Development and Evaluation synthesis approach was used to assess the quality of the evidence. Results: Fourteen studies were included. 16 specific lower extremity injury outcomes were identified. No spinal injury outcomes were identified. Meta-analysis was not possible due to heterogeneity and study quality. All evidence related to PFs and specific lower extremity injury outcomes was of very low to low quality. On the few occasions where multiple studies could be used to compare PFs and outcomes, only two factors demonstrated consensus. A history of previous hamstring injuries (HSI) and increasing age may be prognostic for future HSI in male players. Conclusions: The assumed ability of medical screening tests to predict specific musculoskeletal injuries is not supported by the current evidence. Screening procedures should currently be considered as benchmarks of function or performance only. The prognostic value of load monitoring modalities is unknown. PMID- 29177075 TI - Obesity and elevated blood pressure in suburban student athletes. AB - Objective: To assess the prevalence of obesity and elevated blood pressure in a suburban population of middle school and high school student athletes and examine the differences from the previously published populations. Study design: The Student Athlete Cardiac Evaluation Registry Study is a single-centre, community hospital-based registry study, that provided free annual preparticipation physical examinations (PPE) from 2009 to 2017. The PPE on the 906 athletes included a history, a physical examination and body metrics including height, weight and blood pressure. The blood pressure was measured with an automated blood pressure cuff and, if elevated, was remeasured using a manual blood pressure cuff with aneroid manometer. The data from the PPE were collected and analysed for prevalence of obesity, overweight and elevated blood pressure measurements. Results: The prevalence of obesity was 11%, and 19% of participants were overweight. Many of the athletes had an elevated blood pressure (15%). There was a significant association (P<0.001) between weight and elevated blood pressure. Among athletes with elevated blood pressure, 50% were either obese or overweight. Conclusions: There was a similar prevalence of overweight athletes in our study compared with previously published populations, but there were a lower proportion of obese athletes, which may be explained by differences in demographics. Despite the differences in study populations and the lower rate of obesity, the proportion of athletes with elevated blood pressure in our study was similar to prior populations. Weight issues and elevated blood pressure affect athletes across a range of different populations. PMID- 29177076 TI - Effectiveness and efficiency of different weight machine-based strength training programmes for patients with hip or knee osteoarthritis: a protocol for a quasi experimental controlled study in the context of health services research. AB - Introduction: Osteoarthritis is a chronic musculoskeletal disease with a major impact on the individual and the healthcare system. As there is no cure, therapy aims for symptom release and reduction of disease progression. Physical exercises have been defined as a core treatment for osteoarthritis. However, research questions related to dose response, sustainability of effects, economic efficiency and safety are still open and will be evaluated in this trial, investigating a progressive weight machine-based strength training. Methods and analysis: This is a quasi-experimental controlled trial in the context of health services research. The intervention group (n=300) is recruited from participants of an offer for insurants of a health insurance company suffering from hip or knee osteoarthritis. Potential participants of the control group are selected and written to from the insurance database according to predefined matching criteria. The final statistical twins from the control responders will be determined via propensity score matching (n=300). The training intervention comprises 24 supervised mandatory sessions (2/week) and another 12 facultative sessions (1/week). Exercises include resistance training for the lower extremity and core muscles by use of weight machines and small training devices. The training offer is available at two sites. They differ with respect to the weight machines in use resulting in different dosage parameters. Primary outcomes are self-reported pain and function immediately after the 12-week intervention period. Health-related quality of life, self-efficacy, cost utility and safety will be evaluated as secondary outcomes. Secondary analysis will be undertaken with two strata related to study site. Participants will be followed up 6, 12 and 24 months after baseline. Trial registration number: German Clinical Trial Register DRKS00009257. Pre-results. PMID- 29177077 TI - Acute pseudogout of the foot following Parathyroidectomy: a case report. AB - Background: The current case report is the first in the literature to report the association between parathyroidectomy and an episode of probable pseudogout in the foot in a patient with diabetes mellitus. Case presentation: The authors present a case of pseudogout of the left foot following a subtotal parathyroidectomy in an 80-year-old female with type 2 diabetes mellitus and primary hyperparathyroidism. Pseudogout, also known as calcium pyrophosphate dehydrate deposition disease, is an unusual metabolic sequela following parathyroidectomy. Pseudogout attacks have been noted in the immediate post operative period following parathyroidectomy, but has rarely been identified in the foot. The diagnosis was challenging and there were multiple differential diagnoses that were entertained in this case. Conclusions: This case illustrates the importance of reviewing the surgical history as there might be a link between the previous surgeries and current foot problems. This case also serves as a reminder of the importance of calcium and phosphate metabolism in podiatric health. Most specifically it demonstrates again the association of pseudogout and parathyroidectomy in a patient with diabetes mellitus. Although a rare occurrence, it is an important reminder that metabolic imbalances of calcium levels can manifest in any bone. PMID- 29177078 TI - Which patients presenting with arthralgia eventually develop rheumatoid arthritis? The current state of the art. AB - Early initiation of treatment in patients with inflammatory arthritis at risk of persistence and/or erosive progression is important because it is associated with a reduced rate of progression of joint damage and functional disability. It has been proposed that a window of opportunity exists, during which disease processes are less matured and disease modification can be more effective. The phase of arthralgia preceding clinical arthritis is likely to be an important part of this window of opportunity, during which treatment might prevent progression to clinical arthritis. Several proof-of-concept trials in individuals with arthralgia are now evaluating this hypothesis. Central to such trials is the ability to identify groups at high risk of rheumatoid arthritis (RA) in whom preventive treatment can be tested. This review describes the relevance of adequate prediction making, as well as the accuracy of different types of predictors (including imaging and serological markers) with their value in predicting the progression of arthralgia to arthritis. Despite promising results, studies have been performed in heterogeneous patient populations and most findings have not been validated in independent studies. Future observational or preventive studies should be conducted with homogeneous patient groups (eg, patients fulfilling the European League Against Rheumatism criteria for arthralgia at risk of RA) in order to increase interstudy comparability and to allow result validation. PMID- 29177079 TI - Effect of Fcgamma-receptor 3a (FCGR3A) gene polymorphisms on rituximab therapy in Hungarian patients with rheumatoid arthritis. AB - Background: Rheumatoid arthritis (RA) treatment includes the use of the anti-CD20 monoclonal antibody rituximab (RTX). RTX acts through Fcgamma-receptors (FCGR) on effector natural killer cells and macrophages and it can be administered effectively in RA and in lymphomas. Based on the results of in vitro experiments, its efficacy may depend of FCGR gene polymorphisms in both diseases. Aim: As genetic background of diseases and therapeutic efficacy (pharmacogenetics) may vary among different geographical regions, we wished to assess possible relationships between FCGR3A polymorphism and the therapeutic outcome of RTX therapy in a Hungarian RA cohort. Patients and methods: Altogether, 52 patients, 6 men and 46 women, were included in the study. Peripheral blood samples were used to determine FCGR3A polymorphism by genotyping using real-time PCR method. Results: The distribution of FCGR3A genotypes was 8 VV, 34 VF and 10 FF. Disease activity score 28 (DAS28) reductions in patients with VV, VF and FF genotypes were 1.98+/-0.54 (p=0.008 between DAS28 before and after treatment), 2.07+/-0.23 (p<0.001) and 1.59+/-0.52 (p=0.014), respectively. Significant differences in DAS28 reductions on treatment were found between VF heterozygotes and FF homozygotes (p=0.032), as well as between heterozygotes and all (VV+FF) homozygotes (p=0.017). Furthermore, significantly more VV (62.5%; p=0.030) and VF (64.7%; p=0.015) patients achieved low disease activity compared with FF subjects (30.0%). Conclusion: Our results suggest that FCGR3A polymorphism may predict more effective disease activity reduction by RTX. Furthermore, carrying the V allele may also be associated with better therapeutic response in Hungarian patients with RA. PMID- 29177081 TI - Impact of gender on the response and tolerance to abatacept in patients with rheumatoid arthritis: results from the 'ORA' registry. AB - Objective: The impact of gender on the response and tolerance to abatacept was assessed in a large prospective cohort during 2 years of follow-up. Methods: From the 1017 patients included in the Orencia and Rheumatoid Arthritis registry, disease activity was assessed at baseline, 6, 12 and 24 months. The relationship between the European League Against Rheumatism (EULAR) response, Disease Activity Score 28 (DAS28) remission, rate of adverse events and gender was explored in multivariate analysis. Results: 990 patients, 79.3%female, with at least one follow-up visit were analysed. At baseline, women had longer disease duration, higher disease activity and more often received antitumour necrosis factor (TNF) drugs. The remission was not different between men and women during the follow-up after adjustment on age, disease duration and activity, rheumatoid factor and anti-cyclic citrullinated pyeptide (CCP) positivity, and current disease modifying antirheumatic drugs (DMARDs), previous TNF blockers and corticosteroids use. The proportion of men and women achieving EULAR good-or-moderate response at any endpoints was similar (52.4% vs 55.5%), as well as time to achieving EULAR response (5.4+/-4.9 vs 5.6+/-5.2 months). Moderate EULAR response was more frequent in women at 6 months (OR=1.80, p=0.02) but was no longer significant at 12 or 24 months. During the follow-up, the DAS28, the tender joint count score and the patient global assessment remained higher in women (p=0.001, 0.04 and 0.06, respectively). Drug retention and safety were comparable. Conclusion: In this large daily practice cohort of established rheumatoid arthritis treated with abatacept, women achieved similar remission and EULAR response than men despite higher disease activity and tender joint count during the treatment course. PMID- 29177080 TI - EULAR/ACR classification criteria for adult and juvenile idiopathic inflammatory myopathies and their major subgroups: a methodology report. AB - Objective: To describe the methodology used to develop new classification criteria for adult and juvenile idiopathic inflammatory myopathies (IIMs) and their major subgroups. Methods: An international, multidisciplinary group of myositis experts produced a set of 93 potentially relevant variables to be tested for inclusion in the criteria. Rheumatology, dermatology, neurology and paediatric clinics worldwide collected data on 976 IIM cases (74% adults, 26% children) and 624 non-IIM comparator cases with mimicking conditions (82% adults, 18% children). The participating clinicians classified each case as IIM or non IIM. Generally, the classification of any given patient was based on few variables, leaving remaining variables unmeasured. We investigated the strength of the association between all variables and between these and the disease status as determined by the physician. We considered three approaches: (1) a probability score approach, (2) a sum-of-items approach criteria and (3) a classification tree approach. Results: The approaches yielded several candidate models that were scrutinised with respect to statistical performance and clinical relevance. The probability-score approach showed superior statistical performance and clinical practicability and was therefore preferred over the others. We developed a classification tree for subclassification of patients with IIM. A calculator for electronic devices, such as computers and smartphones, facilitates the use of the European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) classification criteria. Conclusions: The new EULAR/ACR classification criteria provide a patient's probability of having IIM for use in clinical and research settings. The probability is based on a score obtained by summing the weights associated with a set of criteria items. PMID- 29177082 TI - Autoimmune-autoinflammatory rheumatoid arthritis overlaps: a rare but potentially important subgroup of diseases. AB - At the population level, rheumatoid arthritis (RA) is generally viewed as autoimmune in nature with a small subgroup of cases having a palindromic form or systemic autoinflammatory disorder (SAID) phenotype. Herein, we describe resistant cases of classical autoantibody associated RA that had clinical, genetic and therapeutic responses indicative of coexistent autoinflammatory disease. Five patients with clinically overlapping features between RA and SAID including polysynovitis and autoantibody/shared epitope positivity, and who had abrupt severe self-limiting attacks including fevers and serositis, are described. Mutations or single nucleotide polymorphisms in recognised autoinflammatory pathways were evident. Generally, these cases responded poorly to conventional Disease-modifying anti-rheumatic drugs (DMARD) treatment with some excellent responses to colchicine or interleukin 1 pathway blockade. A subgroup of RA cases have a mixed autoimmune-autoinflammatory phenotype and genotype with therapeutic implications.

AB - [This corrects the article DOI: 10.1136/rmdopen-2017-000472.][This corrects the article DOI: 10.1136/rmdopen-2017-000472.]. PMID- 29177084 TI - The prisoner's dilemma as a cancer model. AB - Tumor development is an evolutionary process in which a heterogeneous population of cells with different growth capabilities compete for resources in order to gain a proliferative advantage. What are the minimal ingredients needed to recreate some of the emergent features of such a developing complex ecosystem? What is a tumor doing before we can detect it? We outline a mathematical model, driven by a stochastic Moran process, in which cancer cells and healthy cells compete for dominance in the population. Each are assigned payoffs according to a Prisoner's Dilemma evolutionary game where the healthy cells are the cooperators and the cancer cells are the defectors. With point mutational dynamics, heredity, and a fitness landscape controlling birth and death rates, natural selection acts on the cell population and simulated 'cancer-like' features emerge, such as Gompertzian tumor growth driven by heterogeneity, the log-kill law which (linearly) relates therapeutic dose density to the (log) probability of cancer cell survival, and the Norton-Simon hypothesis which (linearly) relates tumor regression rates to tumor growth rates. We highlight the utility, clarity, and power that such models provide, despite (and because of) their simplicity and built-in assumptions. PMID- 29177085 TI - Sucrose modulation of radiofrequency-induced heating rates and cell death. AB - Background: Applied radiofrequency (RF) energy induces hyperthermia in tissues, facilitating vascular perfusion This study explores the impact of RF radiation on the integrity of the luminal endothelium, and then predominately explores the impact of altering the conductivity of biologically-relevant solutions on RF induced heating rates and cell death. The ability of cells to survive high sucrose (i.e. hyperosmotic conditions) to achieve lower conductivity as a mechanism for directing hyperthermia is evaluated. Methods: RF radiation was generated using a capacitively-coupled radiofrequency system operating at 13.56 MHz. Temperatures were recorded using a FLIR SC 6000 infrared camera. Results: RF radiation reduced cell-to-cell connections among endothelial cells and altered cell morphology towards a more rounded appearance at temperatures reported to cause in vivo vessel deformation. Isotonic solutions containing high sucrose and low levels of NaCl displayed low conductivity and faster heating rates compared to high salt solutions. Heating rates were positively correlated with cell death. Addition of sucrose to serum similarly reduced conductivity and increased heating rates in a dose-dependent manner. Cellular proliferation was normal for cells grown in media supplemented with 125 mM sucrose for 24 hours or for cells grown in 750 mM sucrose for 10 minutes followed by a 24 h recovery period. Conclusions: Sucrose is known to form weak hydrogen bonds in fluids as opposed to ions, freeing water molecules to rotate in an oscillating field of electromagnetic radiation and contributing to heat induction. The ability of cells to survive temporal exposures to hyperosmotic (i.e. elevated sucrose) conditions creates an opportunity to use sucrose or other saccharides to selectively elevate heating in specific tissues upon exposure to a radiofrequency field. PMID- 29177086 TI - Broad-scale redistribution of mRNA abundance and transcriptional machinery in response to growth rate in Salmonella enterica serovar Typhimurium. AB - We have investigated the connection between the four-dimensional architecture of the bacterial nucleoid and the organism's global gene expression programme. By localizing the transcription machinery and the transcriptional outputs across the genome of the model bacterium Salmonella enterica serovar Typhimurium at different stages of the growth cycle, a surprising disconnection between gene dosage and transcriptional output was revealed. During exponential growth, gene output occurred chiefly in the Ori (origin), Ter (terminus) and NSL (non structured left) domains, whereas the Left macrodomain remained transcriptionally quiescent at all stages of growth. The apparently high transcriptional output in Ter was correlated with an enhanced stability of the RNA expressed there during exponential growth, suggesting that longer mRNA half-lives compensate for low gene dosage. During exponential growth, RNA polymerase (RNAP) was detected everywhere, whereas in stationary phase cells, RNAP was concentrated in the Ter macrodomain. The alternative sigma factors RpoE, RpoH and RpoN were not required to drive transcription in these growth conditions, consistent with their observed binding to regions away from RNAP and regions of active transcription. Specifically, these alternative sigma factors were found in the Ter macrodomain during exponential growth, whereas they were localized at the Ori macrodomain in stationary phase. PMID- 29177087 TI - On the (im)possibility of reconstructing plasmids from whole-genome short-read sequencing data. AB - To benchmark algorithms for automated plasmid sequence reconstruction from short read sequencing data, we selected 42 publicly available complete bacterial genome sequences spanning 12 genera, containing 148 plasmids. We predicted plasmids from short-read data with four programs (PlasmidSPAdes, Recycler, cBar and PlasmidFinder) and compared the outcome to the reference sequences. PlasmidSPAdes reconstructs plasmids based on coverage differences in the assembly graph. It reconstructed most of the reference plasmids (recall=0.82), but approximately a quarter of the predicted plasmid contigs were false positives (precision=0.75). PlasmidSPAdes merged 84 % of the predictions from genomes with multiple plasmids into a single bin. Recycler searches the assembly graph for sub-graphs corresponding to circular sequences and correctly predicted small plasmids, but failed with long plasmids (recall=0.12, precision=0.30). cBar, which applies pentamer frequency analysis to detect plasmid-derived contigs, showed a recall and precision of 0.76 and 0.62, respectively. However, cBar categorizes contigs as plasmid-derived and does not bin the different plasmids. PlasmidFinder, which searches for replicons, had the highest precision (1.0), but was restricted by the contents of its database and the contig length obtained from de novo assembly (recall=0.36). PlasmidSPAdes and Recycler detected putative small plasmids (<10 kbp), which were also predicted as plasmids by cBar, but were absent in the original assembly. This study shows that it is possible to automatically predict small plasmids. Prediction of large plasmids (>50 kbp) containing repeated sequences remains challenging and limits the high-throughput analysis of plasmids from short-read whole-genome sequencing data. PMID- 29177088 TI - Genomic characterization of a local epidemic Pseudomonas aeruginosa reveals specific features of the widespread clone ST395. AB - Pseudomonas aeruginosa is a ubiquitous opportunistic pathogen with several clones being frequently associated with outbreaks in hospital settings. ST395 is among these so-called 'international' clones. We aimed here to define the biological features that could have helped the implantation and spread of the clone ST395 in hospital settings. The complete genome of a multidrug resistant index isolate (DHS01) of a large hospital outbreak was analysed. We identified DHS01-specific genetic elements, among which were identified those shared with a panel of six independent ST395 isolates responsible for outbreaks in other hospitals. DHS01 has the fifth largest chromosome of the species (7.1 Mbp), with most of its 1555 accessory genes borne by either genomic islands (GIs, n=48) or integrative and conjugative elements (ICEs, n=5). DHS01 is multidrug resistant mostly due to chromosomal mutations. It displayed signatures of adaptation to chronic infection in part due to the loss of a 131 kbp chromosomal fragment. Four GIs were specific to the clone ST395 and contained genes involved in metabolism (GI-4), in virulence (GI-6) and in resistance to copper (GI-7). GI-7 harboured an array of six copper transporters and was shared with non-pathogenic Pseudomonas sp. retrieved from copper-contaminated environments. Copper resistance was confirmed phenotypically in all other ST395 isolates and possibly accounted for the spreading capability of the clone in hospital outbreaks, where water networks have been incriminated. This suggests that genes transferred from copper-polluted environments may have favoured the implantation and spread of the international clone P. aeruginosa ST395 in hospital settings. PMID- 29177089 TI - ARIBA: rapid antimicrobial resistance genotyping directly from sequencing reads. AB - Antimicrobial resistance (AMR) is one of the major threats to human and animal health worldwide, yet few high-throughput tools exist to analyse and predict the resistance of a bacterial isolate from sequencing data. Here we present a new tool, ARIBA, that identifies AMR-associated genes and single nucleotide polymorphisms directly from short reads, and generates detailed and customizable output. The accuracy and advantages of ARIBA over other tools are demonstrated on three datasets from Gram-positive and Gram-negative bacteria, with ARIBA outperforming existing methods. PMID- 29177090 TI - Completing bacterial genome assemblies with multiplex MinION sequencing. AB - Illumina sequencing platforms have enabled widespread bacterial whole genome sequencing. While Illumina data is appropriate for many analyses, its short read length limits its ability to resolve genomic structure. This has major implications for tracking the spread of mobile genetic elements, including those which carry antimicrobial resistance determinants. Fully resolving a bacterial genome requires long-read sequencing such as those generated by Oxford Nanopore Technologies (ONT) platforms. Here we describe our use of the ONT MinION to sequence 12 isolates of Klebsiella pneumoniae on a single flow cell. We assembled each genome using a combination of ONT reads and previously available Illumina reads, and little to no manual intervention was needed to achieve fully resolved assemblies using the Unicycler hybrid assembler. Assembling only ONT reads with Canu was less effective, resulting in fewer resolved genomes and higher error rates even following error correction with Nanopolish. We demonstrate that multiplexed ONT sequencing is a valuable tool for high-throughput bacterial genome finishing. Specifically, we advocate the use of Illumina sequencing as a first analysis step, followed by ONT reads as needed to resolve genomic structure. PMID- 29177091 TI - Phylogeographic separation and formation of sexually discrete lineages in a global population of Yersinia pseudotuberculosis. AB - Yersinia pseudotuberculosis is a Gram-negative intestinal pathogen of humans and has been responsible for several nationwide gastrointestinal outbreaks. Large scale population genomic studies have been performed on the other human pathogenic species of the genus Yersinia, Yersinia pestis and Yersinia enterocolitica allowing a high-resolution understanding of the ecology, evolution and dissemination of these pathogens. However, to date no purpose-designed large scale global population genomic analysis of Y. pseudotuberculosis has been performed. Here we present analyses of the genomes of 134 strains of Y. pseudotuberculosis isolated from around the world, from multiple ecosystems since the 1960s. Our data display a phylogeographic split within the population, with an Asian ancestry and subsequent dispersal of successful clonal lineages into Europe and the rest of the world. These lineages can be differentiated by CRISPR cluster arrays, and we show that the lineages are limited with respect to inter lineage genetic exchange. This restriction of genetic exchange maintains the discrete lineage structure in the population despite co-existence of lineages for thousands of years in multiple countries. Our data highlights how CRISPR can be informative of the evolutionary trajectory of bacterial lineages, and merits further study across bacteria. PMID- 29177093 TI - Patchy promiscuity: machine learning applied to predict the host specificity of Salmonella enterica and Escherichia coli. AB - Salmonella enterica and Escherichia coli are bacterial species that colonize different animal hosts with sub-types that can cause life-threatening infections in humans. Source attribution of zoonoses is an important goal for infection control as is identification of isolates in reservoir hosts that represent a threat to human health. In this study, host specificity and zoonotic potential were predicted using machine learning in which Support Vector Machine (SVM) classifiers were built based on predicted proteins from whole genome sequences. Analysis of over 1000 S.enterica genomes allowed the correct prediction (67 -90 % accuracy) of the source host for S. Typhimurium isolates and the same classifier could then differentiate the source host for alternative serovars such as S. Dublin. A key finding from both phylogeny and SVM methods was that the majority of isolates were assigned to host-specific sub-clusters and had high host specific SVM scores. Moreover, only a minor subset of isolates had high probability scores for multiple hosts, indicating generalists with genetic content that may facilitate transition between hosts. The same approach correctly identified human versus bovine E. coli isolates (83 % accuracy) and the potential of the classifier to predict a zoonotic threat was demonstrated using E. coli O157. This research indicates marked host restriction for both S. enterica and E. coli, with only limited isolate subsets exhibiting host promiscuity by gene content. Machine learning can be successfully applied to interrogate source attribution of bacterial isolates and has the capacity to predict zoonotic potential. PMID- 29177092 TI - Genome-guided identification of novel head-to-tail cyclized antimicrobial peptides, exemplified by the discovery of pumilarin. AB - The need for novel antibiotics in an era where antimicrobial resistance is on the rise, and the number of new approved antimicrobial drugs reaching the market is declining, is evident. The underused potential of post-translationally modified peptides for clinical use makes this class of peptides interesting candidates. In this study, we made use of the vast amounts of available genomic data and screened all publicly available prokaryotic genomes (~3000) to identify 394 novel head-to-tail cyclized antimicrobial peptides. To verify these in silico results, we isolated and characterized a novel antimicrobial peptide from Bacillus pumilus that we named pumilarin. Pumilarin was demonstrated to have a circular structure and showed antimicrobial activity against several indicator strains, including pathogens. PMID- 29177094 TI - Safety and immunogenicity of MAGE-A3 cancer immunotherapeutic with dacarbazine in patients with MAGE-A3-positive metastatic cutaneous melanoma: an open phase I/II study with a first assessment of a predictive gene signature. AB - Background: We assessed safety, immunogenicity and clinical activity of recombinant MAGE-A3 antigen combined with AS15 immunostimulant (MAGE-A3 immunotherapeutic) in association with dacarbazine in patients with metastatic melanoma. Methods: In this open-label, phase I/II, uncontrolled multicentre trial conducted in Belgium and France, patients with MAGE-A3-positive melanoma received up to 24 doses of MAGE-A3 immunotherapeutic (four cycles) coadministered with eight doses of dacarbazine. Adverse events (AE) were recorded until 31 days postvaccination, and serious AEs (SAE), until 30 days following the last dose. MAGE-A3-specific antibodies were measured by ELISA. Clinical activity of MAGE-A3 immunotherapeutic was assessed in patients positive/negative for previously identified gene signature (GS) associated with clinical outcome. Results: Forty eight patients were enrolled and treated (32 GS+, 15 GS-, 1 unknown GS status); two patients completed the study. All patients reported AEs, the most common were 'general disorders and administration site conditions' (94%). Treatment-related AEs were reported by 85% of patients; the most common was pain at injection site (38%). Sixteen SAEs were reported by 21% of patients; two were considered as treatment related (neutropenia and thrombocytopenia; grade 4). Postdose 4, all patients were seropositive for MAGE-A3-specific antibodies, with a geometric mean titre of 2778.7 ELISA units (EU)/mL (95% CI 1638.3 to 4712.8). One complete and three partial responses were reported (only in GS+ patients). Median overall survival was 11.4 months for GS+ and 5.3 months for GS- patients. Conclusion: Although this trial shows poor results compared with the new results with checkpoint inhibitors, it gives an interesting insight in rapidly developing fields like combinations of immunotherapy and chemotherapy, new generation vaccines and the use of gene profile as a predictive marker.

AB - Cancer diagnosis not only shakes the lives of those who are affected, but also has impacts on the entire family system, which is involved as if it were itself an organism affected by cancer. The oncological illness may cause a breakdown of the existing balance in the family system and demands a progressive degree of mutual adaptation to family members. The 'VoiNoi' Listening Centre of the Campus Bio-Medico University Hospital in Rome has been close to caregivers for several years, to support them in the difficult task of providing assistance through individual or group psychological support therapy and health education. The 'Charter of Rights for Family Caregivers' stems from the experience gained over the years, with the aim of protecting, supporting and strengthening the role and the assistance activity that families carry out in support of their loved ones under conditions of fragility. PMID- 29177095 TI - Targeting immune checkpoints in breast cancer: an update of early results. AB - The immune tumour microenvironment has been shown to play a crucial role in the development and progression of cancer. Expression of gene signatures, reflecting immune activation, and the presence of tumour-infiltrating lymphocytes were associated with favourable outcomes in HER2-positive and triple-negative breast cancer. Recently, immunotherapy with immune checkpoint blockade induced long lasting responses and improved survival in hard-to-treat malignancies (ie, melanoma and non-small cell lung cancer) and are changing treatment paradigms in a variety of neoplastic diseases. Immune checkpoint blockade has been evaluated in breast cancer, particularly in the triple-negative subtype, with promising results observed in monotherapy or in combination with chemotherapy in the metastatic and neoadjuvant settings. However, identification of patients who are most likely to benefit from immune checkpoint blockade remains challenging, with many patients not responding to treatments and a significant financial cost. The combination of immune checkpoint blockade with conventional cancer treatments such as chemotherapy, radiotherapy, targeted therapies or with other immunotherapies is a promising strategy to potentiate its efficacy in breast cancer although further research is required to effectively identify who will respond to these immunotherapies. In this review we report the most recent results that emerged from trials testing immune checkpoint blockade and potential predictive biomarkers and emphasise the new strategies that are under clinical development in breast cancer. PMID- 29177097 TI - Exploration of time points and cut-off values for early tumour shrinkage to predict survival outcomes of patients with metastatic colorectal cancer treated with first-line chemotherapy using a biexponential model for change in tumour size. AB - Background: Several studies reported that early tumour shrinkage (ETS) was associated with overall survival in patients with metastatic colorectal cancer (mCRC) treated with first-line chemotherapy. However, appropriate time point and cut-off value for ETS remain unclear because these varied in previous studies. Patients and methods: We investigated patients with mCRC who received FOLFOX or FOLFIRI with/without molecular-targeted agents as first-line treatment between 2005 and 2014. Using a biexponential model for change in tumour size, a relative change in the sum of the longest diameters of target lesions from baseline was estimated at a certain time point in each individual patient. Associations of survival outcomes with ETS at various time points based on various cut-off values were evaluated by Cox regression analysis with a landmark approach. Results: Among the 67 patients reviewed, the objective response rate was 73.1% (95% CI 62.5% to 83.7%), the median progression-free survival was 10.9 months (95% CI 8.7 to 13.0 months) and the median overall survival was 25.6 months (95% CI 20.1 to 27.3 months). The model for change in tumour size agreed with the actual measured sizes well. Multivariate Cox regression analysis, including performance status, number of metastatic sites and use of targeted agents, showed that ETS at 8 weeks based on a cut-off value of 20% was most significantly associated with overall survival (HR: 0.404, 95% CI 0.231 to 0.707, P=0.0015). Conclusion: It is suggested that a time point of 8 weeks and a cut-off value of 20% may be optimal criteria for defining ETS.

AB - Introduction: To move towards universal health coverage, the government of Kenya introduced free maternity services in all public health facilities in June 2013. User fees are, however, important sources of income for health facilities and their removal has implications for the way in which health facilities are governed. Objective: To explore how implementation of Kenya's financing policy has affected the way in which the rules governing health facilities are made, changed, monitored and enforced. Methods: Qualitative research was carried out using semistructured interviews with 39 key stakeholders from six counties in Kenya: 10 national level policy makers, 10 county level policy makers and 19 implementers at health facilities. Participants were purposively selected using maximum variation sampling. Data analysis was informed by the institutional analysis framework, in which governance is defined by the rules that distribute roles among key players and shape their actions, decisions and interactions. Results: Lack of clarity about the new policy (eg, it was unclear which services were free, leading to instances of service user exploitation), weak enforcement mechanisms (eg, delayed reimbursement to health facilities, which led to continued levying of service charges) and misaligned incentives (eg, the policy led to increased uptake of services thereby increasing the workload for health workers and health facilities losing control of their ability to generate and manage their own resources) led to weak policy implementation, further complicated by the concurrent devolution of the health system. Conclusion: The findings show the consequences of discrepancies between formal institutions and informal arrangements. In introducing new policies, policy makers should ensure that corresponding institutional (re)arrangements, enforcement mechanisms and incentives are aligned with the objectives of the implementers. PMID- 29177099 TI - Estimating the need for inpatient neonatal services: an iterative approach employing evidence and expert consensus to guide local policy in Kenya. AB - Universal access to quality newborn health services will be essential to meeting specific Sustainable Development Goals to reduce neonatal and overall child mortality. Data for decision making are crucial for planning services and monitoring progress in these endeavours. However, gaps in local population-level and facility-based data hinder estimation of health service requirements for effective planning in many low-income and middle-income settings. We worked with local policy makers and experts in Nairobi City County, an area with a population of four million and the highest neonatal mortality rate amongst counties in Kenya, to address this gap, and developed a systematic approach to use available data to support policy and planning. We developed a framework to identify major neonatal conditions likely to require inpatient neonatal care and identified estimates of incidence through literature review and expert consultation, to give an overall estimate for the year 2017 of the need for inpatient neonatal care, taking account of potential comorbidities. Our estimates suggest that almost 1 in 5 newborns (183/1000 live births) in Nairobi City County may need inpatient care, resulting in an estimated 24 161 newborns expected to require care in 2017. Our approach has been well received by local experts, who showed a willingness to work together and engage in the use of evidence in healthcare planning. The process highlighted the need for co-ordinated thinking on admission policy and referral care especially in a pluralistic provider environment helping build further appetite for data-informed decision making. PMID- 29177100 TI - 20 years of gender mainstreaming in health: lessons and reflections for the neglected tropical diseases community. AB - Neglected tropical diseases (NTDs) affect the poorest of the poor. NTD programmes can and should rise to the challenge of playing a part in promoting more gender equitable societies. Gender equity shapes poverty and the experience of disease in multiple ways; yet to date, there has been little attention paid to gender equity in NTD control efforts. Drawing on a synthesis of relevant literature, the tacit knowledge and experience of the authors, and discussions at a meeting on women, girls and NTDs, this analysis paper distills five key lessons from over 20 years of gender mainstreaming in health. The paper links this learning to NTDs and Mass Drug Administration (MDA). Our first lesson is that tailored gender frameworks support gender analysis within research and programming. We present a gender review framework focusing on different MDA strategies. Second, gender interplays with other axes of inequality, such as disability and geographical location; hence, intersectionality is important for inclusive and responsive NTD programmes. Third, gender, power and positionality shape who is chosen as community drug distributors (CDDs). How CDDs interact with communities and how this interface role is valued and practised needs to be better understood. Fourth, we need to unpack the gender and power dynamics at household level to assess how this impacts MDA coverage and interactions with CDDs. Finally, we need to collect and use sex disaggregated data to support the development of more equitable and sustainable NTD programmes. PMID- 29177101 TI - From blockchain technology to global health equity: can cryptocurrencies finance universal health coverage? AB - Blockchain technology and cryptocurrencies could remake global health financing and usher in an era global health equity and universal health coverage. We outline and provide examples for at least four important ways in which this potential disruption of traditional global health funding mechanisms could occur: universal access to financing through direct transactions without third parties; novel new multilateral financing mechanisms; increased security and reduced fraud and corruption; and the opportunity for open markets for healthcare data that drive discovery and innovation. We see these issues as a paramount to the delivery of healthcare worldwide and relevant for payers and providers of healthcare at state, national and global levels; for government and non governmental organisations; and for global aid organisations, including the WHO, International Monetary Fund and World Bank Group. PMID- 29177102 TI - Assessment of R18, COG1410, and APP96-110 in Excitotoxicity and Traumatic Brain Injury. AB - Cationic arginine-rich and poly-arginine peptides (referred to as CARPs) have potent neuroprotective properties in in vitro excitotoxicity and in vivo models of stroke. Traumatic brain injury (TBI) shares many pathophysiological processes as stroke, including excitotoxicity. Therefore, we evaluated our lead peptide, poly-arginine R18, with the COG1410 and APP96-110 peptides, which have neuroprotective actions following TBI. In an in vitro cortical neuronal glutamic acid excitotoxicity injury model, R18 was highly neuroprotective and reduced neuronal calcium influx, while COG1410 and APP96-110 displayed modest neuroprotection and were less effective at reducing calcium influx. In an impact acceleration closed-head injury model (Marmarou model), R18, COG1410, and APP96 110 were administered intravenously (300 nmol/kg) at 30 minutes after injury in male Sprague-Dawley rats. When compared to vehicle, no peptide significantly improved functional outcomes, however the R18 and COG1410 treatment groups displayed positive trends in the adhesive tape test and rotarod assessments. Similarly, no peptide had a significant effect on hippocampal neuronal loss, however a significant reduction in axonal injury was observed for R18 and COG1410. In conclusion, this study has demonstrated that R18 is significantly more effective than COG1410 and APP96-110 at reducing neuronal injury and calcium influx following excitotoxicity, and that both R18 and COG1410 reduce axonal injury following TBI. Additional dose response and treatment time course studies are required to further assess the efficacy of R18 in TBI. PMID- 29177103 TI - Postural Control and Emotion in Children with Autism Spectrum Disorders. AB - Autism Spectrum Disorders subjects (ASD) are well known to have deficits in social interaction. We recorded simultaneously eye movements and postural sway during exploration of emotional faces in children with ASD and typically developing children (TD). We analyzed several postural and ocular parameters. The results showed that all postural parameters were significantly greater in children with ASD; ASD made significantly fewer saccades and had shorter fixation time than TD, particularly in the eyes, and especially for unpleasant emotions. These results suggest that poor postural control of ASD and their impaired visual strategies could be due to a lack of interest in social cognition, causing a delay in the development of the cortical areas, and thus could have an effect on their postural control. PMID- 29177104 TI - Environmental proteomics reveals taxonomic and functional changes in an enriched aquatic ecosystem. AB - Aquatic ecosystem enrichment can lead to distinct and irreversible changes to undesirable states. Understanding changes in active microbial community function and composition following organic-matter loading in enriched ecosystems can help identify biomarkers of such state changes. In a field experiment, we enriched replicate aquatic ecosystems in the pitchers of the northern pitcher plant, Sarracenia purpurea. Shotgun metaproteomics using a custom metagenomic database identified proteins, molecular pathways, and contributing microbial taxa that differentiated control ecosystems from those that were enriched. The number of microbial taxa contributing to protein expression was comparable between treatments; however, taxonomic evenness was higher in controls. Functionally active bacterial composition differed significantly among treatments and was more divergent in control pitchers than enriched pitchers. Aerobic and facultative anaerobic bacteria contributed most to identified proteins in control and enriched ecosystems, respectively. The molecular pathways and contributing taxa in enriched pitcher ecosystems were similar to those found in larger enriched aquatic ecosystems and are consistent with microbial processes occurring at the base of detrital food webs. Detectable differences between protein profiles of enriched and control ecosystems suggest that a time series of environmental proteomics data may identify protein biomarkers of impending state changes to enriched states. PMID- 29177106 TI - Anti-M Alloimmunization: Management and Outcome at a Single Institution. AB - Objective The objective of this study was to review the management strategies and outcomes in gravidas with anti-M alloimmunization over 15 years. Study Design Data collected from 195 pregnant patients with anti-M antibodies from July 2000 through June 2016 were reviewed retrospectively. We analyzed indirect antiglobulin test titer results, paternal or fetal/neonatal M antigen status, antepartum course, and perinatal outcomes. Results Anti-M antibodies were found in 146 women and 195pregnancies. Among those with positive indirect antiglobulin tests, 193 pregnancies had titers at or below 1:4. Only one patient with an initial low titer experienced a more than twofold increase to a titer 1:64. Two women underwent an amniocentesis and cordocentesis. Ninety-five (73.6%) of the 129 infants tested were positive for the M antigen. Nine infants required phototherapy. There were no cases of hemolytic disease of the fetus or newborn, mild or severe. Conclusion The incidence of severe hemolytic disease of the newborn due to anti-M is extremely low. We found no cases in our review of 195 pregnancies, despite several cases of severe hemolytic disease of the newborn reported in the literature. We have created an algorithm for the management of anti-M antibodies in pregnancy based on our data and extensive literature review. PMID- 29177105 TI - Investigating Molecular Connections of Non-alcoholic Fatty Liver Disease with Associated Pathological Conditions in West Virginia for Biomarker Analysis. AB - Non-alcoholic fatty liver disease (NAFLD) is a disease characterized by a steatosis of the liver that may progress to more serious pathological conditions including: nonalcoholic steatohepatitis (NASH), fibrosis, and cirrhosis. As the prevalence of NAFLD has increased worldwide in recent years, pathophysiology and risk factors associated with disease progression of NAFLD are at the focus of many studies. NAFLD is related to and shares common serum biomarkers with cardiovascular disease (CVD), type 2 diabetes mellitus (T2DM), obesity, and metabolic syndrome (MetS). West Virginia (WV) is a state with some of the highest rates of CVD, obesity and diabetes mellitus. As NAFLD is closely related to these diseases, it is of particular interest in WV. Currently there is no cost effective, standardized method used clinically to detect NAFLD prior to the onset of reversible complications. At this time, the diagnosis of NAFLD is made with costly radiologic studies and invasive biopsy. These studies are only diagnostic once changes to hepatic tissue have occurred. The diagnosis of NAFLD by traditional methods may not allow for successful intervention and may not be readily available in areas with already sparse medical resources. In this literature review, we identify a list of biomarkers common among CVD, T2DM, obesity, MetS and NAFLD. From this research we propose the following biomarkers are good candidates for inclusion in a panel of biomarkers for the early detection of NAFLD: adiponectin, AST, ALT, apo-B, CK18, CPS1, CRP, FABP-1, ferritin, GGT, GRP78, HDL-C, IGF-1, IL-1beta, 6, 8, 10, IRS-2PAI-1, leptin, lumican, MDA SREBP-1c and TNF-alpha. Creating and implementing a biomarker panel for the early detection and attenuation of NAFLD, prior to the onset of irreversible complication would provide maximum benefit and decrease the disease burden on the patients and healthcare system of WV. PMID- 29177107 TI - Treatment of Morbidly Adherent Placentation Utilizing a Standardized Multidisciplinary Approach in the Community Hospital-Private Practice Setting. AB - Objective Morbidly adherent placentation is associated with increased maternal morbidity and mortality. Recently, there has been mounting evidence supporting the benefits of a standardized multidisciplinary approach at tertiary teaching hospitals. Our objective was to estimate the impact of the implementation of a similar program at a high-volume private community hospital. Study Design In this retrospective cohort study, we evaluated maternal outcomes in all cases of histopathologically confirmed morbidly adherent placentation since the initiation of our multidisciplinary program (2012-2016). Our data were compared with the previously published outcomes of two large cohorts from tertiary teaching hospitals in Utah and Texas. Results In the 28 cases included for evaluation, our group's median estimated blood loss, median packed red blood cells transfused, median anesthesia time, median length of stay, or rates of maternal morbidity did not statistically differ from the published data in Utah or Texas. Conclusion Our data demonstrate the feasibility and utility of a multidisciplinary morbidly adherent placentation program in the private practice/community hospital setting with outcomes similar to those at tertiary teaching hospitals. Implementation of such program may prove beneficial in remote centers, where various factors may prohibit patient travel to a larger center. PMID- 29177108 TI - Sex Differences in the Expression of Drug-Metabolizing and Transporter Genes in Human Liver. AB - Human sex differences in the gene expression of drug metabolizing enzymes and transporters (DMETs) introduce differences in drug absorption, distribution, metabolism and excretion, possibly affecting drug efficacy and adverse reactions. However, existing studies aimed at identifying dimorphic expression differences of DMET genes are limited by sample size and the number of genes profiled. Focusing on a list of 374 DMET genes, we analyzed a previously published gene expression data set consisting of human male (n=234) and female (n=193) liver samples, and identified 77 genes showing differential expression due to sex. To delineate the biological functionalities and regulatory mechanisms for the differentially expressed DMET genes, we conducted a co-expression network analysis. Moreover, clinical implications of sex differences in the expression of human hepatic DMETs are discussed. This study may contribute to the realization of personalized medicine by better understanding the inter-individual differences between males and females in drug/xenobiotic responses and human disease susceptibilities. PMID- 29177109 TI - Exome Sequencing of Extended Families with Alzheimer's Disease Identifies Novel Genes Implicated in Cell Immunity and Neuronal Function. AB - Objective: Alzheimer's disease (AD) is a neurodegenerative disorder for which more than 20 genetic loci have been implicated to date. However, studies demonstrate not all genetic factors have been identified. Therefore, in this study we seek to identify additional rare variants and novel genes potentially contributing to AD. Methods: Whole exome sequencing was performed on 23 multi generational families with an average of eight affected subjects. Exome sequencing was filtered for rare, nonsynonymous and loss-of-function variants. Alterations predicted to have a functional consequence and located within either a previously reported AD gene, a linkage peak (LOD>2), or clustering in the same gene across multiple families, were prioritized. Results: Rare variants were found in known AD risk genes including AKAP9, CD33, CR1, EPHA1, INPP5D, NME8, PSEN1, SORL1, TREM2 and UNC5C. Three families had five variants of interest in linkage regions with LOD>2. Genes with segregating alterations in these peaks include CD163L1 and CLECL1, two genes that have both been implicated in immunity, CTNNA1, which encodes a catenin in the cerebral cortex and MIEF1, a gene that may induce mitochondrial dysfunction and has the potential to damage neurons. Four genes were identified with alterations in more than one family include PLEKHG5, a gene that causes Charcot-Marie-Tooth disease and THBS2, which promotes synaptogenesis. Conclusion: Utilizing large families with a heavy burden of disease allowed for the identification of rare variants co-segregating with disease. Variants were identified in both known AD risk genes and in novel genes. PMID- 29177110 TI - Advances in the Understanding and Treatment of Mitochondrial Fatty Acid Oxidation Disorders. AB - Purpose of review: This review focuses on advances made in the past three years with regards to understanding the mitochondrial fatty acid oxidation (FAO) pathway, the pathophysiological ramifications of genetic lesions in FAO enzymes, and emerging therapies for FAO disorders. Recent findings: FAO has now been recognized to play a key energetic role in pulmonary surfactant synthesis, T-cell differentiation and memory, and the response of the proximal tubule to kidney injury. Patients with FAO disorders may face defects in these cellular systems as they age. Aspirin, statins, and nutritional supplements modulate the rate of FAO under normal conditions and could be risk factors for triggering symptoms in patients with FAO disorders. Patients have been identified with mutations in the ACAD9 and ECHS1 genes, which may represent new FAO disorders. New interventions for long-chain FAODs are in clinical trials. Finally, post-translational modifications that regulate fatty acid oxidation protein activities have been characterized that represent important new therapeutic targets. Summary: Recent research has led to a deeper understanding of FAO. New therapeutic avenues are being pursued that may ultimately cause a paradigm shift for patient care. PMID- 29177111 TI - The reanalysis of biogeography of the Asian tree frog, Rhacophorus (Anura: Rhacophoridae): geographic shifts and climatic change influenced the dispersal process and diversification. AB - Rapid uplifts of the Tibetan Plateau and climate change in Asia are thought to have profoundly modulated the diversification of most of the species distributed throughout Asia. The ranoid tree frog genus Rhacophorus, the largest genus in the Rhacophoridae, is widely distributed in Asia and especially speciose in the areas south and east of the Tibetan Plateau. Here, we infer phylogenetic relationships among species and estimate divergence times, asking whether the spatiotemporal characteristics of diversification within Rhacophorus were related to rapid uplifts of the Tibetan Plateau and concomitant climate change. Phylogenetic analysis recovered distinct lineage structures in Rhacophorus, which indicated a clear distribution pattern from Southeast Asia toward East Asia and India. Molecular dating suggests that the first split within the genus date back to the Middle Oligocene (approx. 30 Ma). The Rhacophorus lineage through time (LTT) showed that there were periods of increased speciation rate: 14-12 Ma and 10-4 Ma. In addition, ancestral area reconstructions supported Southeast Asia as the ancestral area of Rhacophorus. According to the results of molecular dating, ancestral area reconstructions and LTT we think the geographic shifts, the staged rapid rises of the Tibetan Plateau with parallel climatic changes and reinforcement of the Asian monsoons (15 Ma, 8 Ma and 4-3 Ma), possibly prompted a burst of diversification in Rhacophorus. PMID- 29177115 TI - Levels of detail analysis of microwave scattering from human head models for brain stroke detection. AB - In this paper, we have presented a microwave scattering analysis from multiple human head models. This study incorporates different levels of detail in the human head models and its effect on microwave scattering phenomenon. Two levels of detail are taken into account; (i) Simplified ellipse shaped head model (ii) Anatomically realistic head model, implemented using 2-D geometry. In addition, heterogenic and frequency-dispersive behavior of the brain tissues has also been incorporated in our head models. It is identified during this study that the microwave scattering phenomenon changes significantly once the complexity of head model is increased by incorporating more details using magnetic resonance imaging database. It is also found out that the microwave scattering results match in both types of head model (i.e., geometrically simple and anatomically realistic), once the measurements are made in the structurally simplified regions. However, the results diverge considerably in the complex areas of brain due to the arbitrary shape interface of tissue layers in the anatomically realistic head model. After incorporating various levels of detail, the solution of subject microwave scattering problem and the measurement of transmitted and backscattered signals were obtained using finite element method. Mesh convergence analysis was also performed to achieve error free results with a minimum number of mesh elements and a lesser degree of freedom in the fast computational time. The results were promising and the E-Field values converged for both simple and complex geometrical models. However, the E-Field difference between both types of head model at the same reference point differentiated a lot in terms of magnitude. At complex location, a high difference value of 0.04236 V/m was measured compared to the simple location, where it turned out to be 0.00197 V/m. This study also contributes to provide a comparison analysis between the direct and iterative solvers so as to find out the solution of subject microwave scattering problem in a minimum computational time along with memory resources requirement. It is seen from this study that the microwave imaging may effectively be utilized for the detection, localization and differentiation of different types of brain stroke. The simulation results verified that the microwave imaging can be efficiently exploited to study the significant contrast between electric field values of the normal and abnormal brain tissues for the investigation of brain anomalies. In the end, a specific absorption rate analysis was carried out to compare the ionizing effects of microwave signals to different types of head model using a factor of safety for brain tissues. It is also suggested after careful study of various inversion methods in practice for microwave head imaging, that the contrast source inversion method may be more suitable and computationally efficient for such problems. PMID- 29177113 TI - PBxplore: a tool to analyze local protein structure and deformability with Protein Blocks. AB - This paper describes the development and application of a suite of tools, called PBxplore, to analyze the dynamics and deformability of protein structures using Protein Blocks (PBs). Proteins are highly dynamic macromolecules, and a classical way to analyze their inherent flexibility is to perform molecular dynamics simulations. The advantage of using small structural prototypes such as PBs is to give a good approximation of the local structure of the protein backbone. More importantly, by reducing the conformational complexity of protein structures, PBs allow analysis of local protein deformability which cannot be done with other methods and had been used efficiently in different applications. PBxplore is able to process large amounts of data such as those produced by molecular dynamics simulations. It produces frequencies, entropy and information logo outputs as text and graphics. PBxplore is available at https://github.com/pierrepo/PBxplore and is released under the open-source MIT license. PMID- 29177114 TI - Uncovering the relationship and mechanisms of Tartary buckwheat (Fagopyrum tataricum) and Type II diabetes, hypertension, and hyperlipidemia using a network pharmacology approach. AB - Background: Tartary buckwheat (TB), a crop rich in protein, dietary fiber, and flavonoids, has been reported to have an effect on Type II diabetes (T2D), hypertension (HT), and hyperlipidemia (HL). However, limited information is available about the relationship between Tartary buckwheat and these three diseases. The mechanisms of how TB impacts these diseases are still unclear. Methods: In this study, network pharmacology was used to investigate the relationship between the herb as well as the diseases and the mechanisms of how TB might impact these diseases. Results: A total of 97 putative targets of 20 compounds found in TB were obtained. Then, an interaction network of 97 putative targets for these compounds and known therapeutic targets for the treatment of the three diseases was constructed. Based on the constructed network, 28 major nodes were identified as the key targets of TB due to their importance in network topology. The targets of ATK2, IKBKB, RAF1, CHUK, TNF, JUN, and PRKCA were mainly involved in fluid shear stress and the atherosclerosis and PI3K-Akt signaling pathways. Finally, molecular docking simulation showed that 174 pairs of chemical components and the corresponding key targets had strong binding efficiencies. Conclusion: For the first time, a comprehensive systemic approach integrating drug target prediction, network analysis, and molecular docking simulation was developed to reveal the relationships and mechanisms between the putative targets in TB and T2D, HT, and HL. PMID- 29177112 TI - Transcriptome sequencing reveals high isoform diversity in the ant Formica exsecta. AB - Transcriptome resources for social insects have the potential to provide new insight into polyphenism, i.e., how divergent phenotypes arise from the same genome. Here we present a transcriptome based on paired-end RNA sequencing data for the ant Formica exsecta (Formicidae, Hymenoptera). The RNA sequencing libraries were constructed from samples of several life stages of both sexes and female castes of queens and workers, in order to maximize representation of expressed genes. We first compare the performance of common assembly and scaffolding software (Trinity, Velvet-Oases, and SOAPdenovo-trans), in producing de novo assemblies. Second, we annotate the resulting expressed contigs to the currently published genomes of ants, and other insects, including the honeybee, to filter genes that have annotation evidence of being true genes. Our pipeline resulted in a final assembly of altogether 39,262 mRNA transcripts, with an average coverage of >300X, belonging to 17,496 unique genes with annotation in the related ant species. From these genes, 536 genes were unique to one caste or sex only, highlighting the importance of comprehensive sampling. Our final assembly also showed expression of several splice variants in 6,975 genes, and we show that accounting for splice variants affects the outcome of downstream analyses such as gene ontologies. Our transcriptome provides an outstanding resource for future genetic studies on F. exsecta and other ant species, and the presented transcriptome assembly can be adapted to any non-model species that has genomic resources available from a related taxon. PMID- 29177116 TI - The ability of laying pullets to negotiate two ramp designs as measured by bird preference and behaviour. AB - Background: Laying hens are often kept in barn or free-range systems where they must negotiate level changes in the house to access resources. However, collisions and resultant keel fractures are commonplace. Producers sometimes add ramps to make raised areas more accessible but designs vary and very little research has investigated bird preference or behaviour when using different ramp designs, or the effect of ramp design on falls and collisions. Methods: Two ramp designs were studied in an experimental setting-a ramp made of plastic poultry slats (grid ramp, GR) and a ramp made of wooden rungs (ladder ramp, LR). Sixty four young female hens were trained to move to a food reward and this was used to test their behavioural responses when first negotiating the two different ramps during individual tests. Both upward and downward transitions were studied. Ramp preference was also tested using a room that replicated a commercial single-tier system with both types of ramp available. Birds were placed in this room in groups of 16 for three days and their use of the ramps studied. Results: A greater percentage of birds successfully completed (reached the reward bowl) on the GR than the LR during both upward (58% vs 37%) and downward (83% vs 73%) transitions, and a smaller percentage of birds made zero attempts to use the GR than the LR (upwards: 13% vs 56%, downwards: 8% vs 26%). When making a downward transition, more hesitation behaviours were seen (head orientations, stepping on the spot, moving away) for the LR. However, more head orientations were seen for the GR during the upward transition. Birds were more likely to abort attempts (an attempt began when a bird placed both feet on the ramp) to move up the GR than the LR. Birds took longer to negotiate the LR than the GR in both directions, and more pauses were seen during a successful upward transition on the LR. Birds were more likely to move down the GR by walking/running whereas birds tended to jump over the entire LR. More collisions with the food reward bowl were seen for the LR. In the group tests, birds preferred to use the GR, with more transitions seen at all timepoints. However, in these tests, birds preferred to rest on the LR with greater numbers of birds counted on this type of ramp during scan sampling at all timepoints. Discussion: Behavioural results suggest that the GR was easier for the birds to use than the LR, particularly on the downward transition. The GR was also less likely to result in collisions. However, the upward transition may be more difficult on the GR for some birds, potentially because of the inability to pause on a level surface during the transition. The results suggest that the GR was preferred by pullets for moving between a raised area and the ground but the LR was preferred for resting. PMID- 29177117 TI - Gene and genome-centric analyses of koala and wombat fecal microbiomes point to metabolic specialization for Eucalyptus digestion. AB - The koala has evolved to become a specialist Eucalyptus herbivore since diverging from its closest relative, the wombat, a generalist herbivore. This niche adaptation involves, in part, changes in the gut microbiota. The goal of this study was to compare koala and wombat fecal microbiomes using metagenomics to identify potential differences attributable to dietary specialization. Several populations discriminated between the koala and wombat fecal communities, most notably S24-7 and Synergistaceae in the koala, and Christensenellaceae and RF39 in the wombat. As expected for herbivores, both communities contained the genes necessary for lignocellulose degradation and urea recycling partitioned and redundantly encoded across multiple populations. Secondary metabolism was overrepresented in the koala fecal samples, consistent with the need to process Eucalyptus secondary metabolites. The Synergistaceae population encodes multiple pathways potentially relevant to Eucalyptus compound metabolism, and is predicted to be a key player in detoxification of the koala's diet. Notably, characterized microbial isolates from the koala gut appear to be minor constituents of this habitat, and the metagenomes provide the opportunity for genome-directed isolation of more representative populations. Metagenomic analysis of other obligate and facultative Eucalyptus folivores will reveal whether putatively detoxifying bacteria identified in the koala are shared across these marsupials. PMID- 29177118 TI - Development of medical informatics in China over the past 30 years from a conference perspective and a Sino-American comparison. AB - Background: As the world's second-largest economy, China has launched health reforms for the second time and invested significant funding in medical informatics (MI) since 2010; however, few studies have been conducted on the outcomes of this ambitious cause. Objective: This study analyzed the features of major MI meetings held in China and compared them with similar MI conferences in the United States, aiming at informing researchers on the outcomes of MI in China and the US from the professional conference perspective and encouraging greater international cooperation for the advancement of the field of medical informatics in China and, ultimately, the promotion of China's health reform. Methods: Qualitative and quantitative analyses of four MI meetings in China (i.e., CMIAAS, CHINC, CHITEC, and CPMI) and two in the US (i.e., AMIA and HIMSS) were conducted. Furthermore, the size, constituent parts and regional allocation of participants, topics, and fields of research for each meeting were determined and compared. Results: From 1985 to 2016, approximately 45,000 individuals attended the CMIAAS and CPMI (academic), CHINC and CHITEC (industry), resulting in 5,085 documented articles. In contrast, in 2015, 38,000 and 3,700 individuals, respectively, attended the American HIMSS (industry) and AMIA (academic) conferences and published 1,926 papers in the latter. Compared to those of HIMSS in 2015, the meeting duration of Chinese industry CHITEC was 3 vs. 5 days, the number of vendors was 100 vs. 1,500+, the number of sub-forums was 10 vs. 250; while compared to those of AMIA, the meeting duration of Chinese CMIAAS was 2 vs. 8 days, the number of vendors was 5 vs. 65+, the number of sub-forums was 4 vs. 26. HIMSS and AMIA were more open, international, and comprehensive in comparison to the aforementioned Chinese conferences. Conclusions: The current MI in China can be characterized as "hot in industry application, and cold in academic research." Taking into consideration the economic scale together with the huge investment in MI, conference yield and attendee diversity are still low in China. This study demonstrates an urgent necessity to elevate the medical informatics discipline in China and to expand research fields in order to maintain pace with the development of medical informatics in the US and other countries. PMID- 29177120 TI - Morphological convergence in 'river dolphin' skulls. AB - Convergent evolution can provide insights into the predictability of, and constraints on, the evolution of biodiversity. One striking example of convergence is seen in the 'river dolphins'. The four dolphin genera that make up the 'river dolphins' (Inia geoffrensis, Pontoporia blainvillei, Platanista gangetica and Lipotes vexillifer) do not represent a single monophyletic group, despite being very similar in morphology. This has led many to using the 'river dolphins' as an example of convergent evolution. We investigate whether the skulls of the four 'river dolphin' genera are convergent when compared to other toothed dolphin taxa in addition to identifying convergent cranial and mandibular features. We use geometric morphometrics to uncover shape variation in the skulls of the 'river dolphins' and then apply a number of phylogenetic techniques to test for convergence. We find significant convergence in the skull morphology of the 'river dolphins'. The four genera seem to have evolved similar skull shapes, leading to a convergent morphotype characterised by elongation of skull features. The cause of this morphological convergence remains unclear. However, the features we uncover as convergent, in particular elongation of the rostrum, support hypotheses of shared feeding mode or diet and thus provide the foundation for future work into convergence within the Odontoceti.

AB - Background: Skin microbiome varies from person to person due to a combination of various factors, including age, biogeography, sex, cosmetics and genetics. Many skin disorders appear to be related to the resident microflora, yet databases of facial skin microbiome of many biogeographies, including Thai, are limited. Methods: Metagenomics derived B-RISA and 16S rRNA gene sequencing was utilized to identify the culture-independent bacterial diversity on Thai male faces (cheek and forehead areas). Skin samples were categorized (grouped) into (i) normal (teenage.hea) and (ii) acne-prone (teenage.acn) young adults, and normal (iii) middle-aged (middle.hea) and (iv) elderly (elderly.hea) adults. Results: The 16S rRNA gene sequencing was successful as the sequencing depth had an estimated >98% genus coverage of the true community. The major diversity was found between the young and elderly adults in both cheek and forehead areas, followed by that between normal and acne young adults. Detection of representative characteristics indicated that bacteria from the order Rhizobiales, genera Sphingomonas and Pseudoalteromonas, distinguished the elderly.hea microbiota, along the clinical features of wrinkles and pores. Prediction of the metabolic potential revealed reduced metabolic pathways involved in replication and repair, nucleotide metabolism and genetic translation in the elderly.hea compared with that in the teenage.hea. For young adults, some unique compositions such as abundance of Propionibacterium acnes and Staphylococcus epidermidis, with a minor diversity between normal and acne skins, were detected. The metabolic potentials of the acne vs. normal young adults showed that teenage.acn was low in many cellular processes (e.g., cell motility and environmental adaptation), but high in carbohydrate metabolism, which could support acne growth. Moreover, comparison with the age-matched males from the US (Boulder, Colorado) to gain insight into the diversity across national biogeography, revealed differences in the distribution pattern of species, although common bacteria were present in both biogeographical samples. Furthermore, B-RISA served as a crosscheck result to the 16S rRNA gene sequencing (i.e., differences between teenage and elderly microbiota). Conclusions: This study revealed and compared the microbial diversity on different aged Thai male faces, and included analyses for representing the bacterial flora, the clinical skin characteristics, and comparison with the US age-matched. The results represent the first skin microbiota of Thai males, and helps the design of a large-scale skin microbiome study of Thais. The findings of the diversity among ages, skin type and national biogeography supported the importance of these traits in the skin microbiome and in developing a safe and sustainable treatment for acne and aging skin diseases. PMID- 29177122 TI - Subject-Specific Biomechanical Modelling of the Oropharynx: Towards Speech Production. AB - Biomechanical models of the oropharynx are beneficial to treatment planning of speech impediments by providing valuable insight into the speech function such as motor control. In this paper, we develop a subject-specific model of the oropharynx and investigate its utility in speech production. Our approach adapts a generic tongue-jaw-hyoid model (Stavness et al. 2011) to fit and track dynamic volumetric MRI data of a normal speaker, subsequently coupled to a source-filter based acoustic synthesizer. We demonstrate our model's ability to track tongue tissue motion, simulate plausible muscle activation patterns, as well as generate acoustic results that have comparable spectral features to the associated recorded audio. Finally, we propose a method to adjust the spatial resolution of our subject-specific tongue model to match the fidelity level of our MRI data and speech synthesizer. Our findings suggest that a higher resolution tongue model - using similar muscle fibre definition - does not show a significant improvement in acoustic performance, for our speech utterance and at this level of fidelity; however we believe that our approach enables further refinements of the muscle fibres suitable for studying longer speech sequences and finer muscle innervation using higher resolution dynamic data. PMID- 29177123 TI - Recent Advances in Adhesive Bonding - The Role of Biomolecules, Nanocompounds, and Bonding Strategies in Enhancing Resin Bonding to Dental Substrates. AB - Purpose of review: To present an overview on the main agents (i.e., biomolecules and nanocompounds) and/or strategies currently available to amplify or stabilize resin-dentin bonding. Recent findings: According to studies retrieved for full text reading (2014-2017), there are currently six major strategies available to overcome resin-dentin bond degradation: (i) use of collagen crosslinking agents, which may form stable covalent bonds with collagen fibrils, thus strengthening the hybrid layer; (ii) use of antioxidants, which may allow further polymerization reactions over time; (iii) use of protease inhibitors, which may inhibit or inactivate metalloproteinases; (iv) modification of the bonding procedure, which may be performed by using the ethanol wet-bonding technique or by applying an additional adhesive (hydrophobic) coating, thereby strengthening the hybrid layer; (v) laser treatment of the substrate prior to bonding, which may cause specific topographic changes in the surface of dental substrates, increasing bonding efficacy; and (vi) reinforcement of the resin matrix with inorganic fillers and/or remineralizing agents, which may positively enhance physico-mechanical properties of the hybrid layer. Summary: With the present review, we contributed to the better understanding of adhesion concepts and mechanisms of resin-dentin bond degradation, showing the current prospects available to solve that problematic. Also, adhesively-bonded restorations may be benefited by the use of some biomolecules, nanocompounds or alternative bonding strategies in order to minimize bond strength degradation.

AB - Objective: To evaluate patients' views on health service initiatives established to improve uptake of NHS primary dental care amongst adult patients in a socially deprived area, comparing practices with extended and regular contract capacity. Study design: Service evaluation and cross-sectional survey. Method: Questionnaire survey of patients attending a random sample of dental practices in three inner-metropolitan boroughs of south London following initiatives to improve access to dental care (across dental practices delivering regular and extended contracts for services) exploring attendance patterns and the influence and awareness of local initiatives to promote access. Results: Four hundred fifty adults across 12 dental practices completed questionnaires: 79% reported attending for routine and 21% for urgent care. Patients were most aware of banners outside practices, followed by dental advertisements in newspapers. Vouchers for free treatments were considered of the highest possible influence, followed by vouchers for reduced treatment costs and an emergency out-of-hours helpline. Awareness and influence were not aligned, and there was no evidence of difference by practice contract type whilst there were differences by age and type of attendance. Conclusion: The findings suggest that financial incentives and emergency services are considered the most influential initiatives for adult patients whose attendance patterns appear to be related to personal circumstances rather than merely being influenced by the provision of information. PMID- 29177124 TI - Harnessing Apoptotic Cells for Transplantation Tolerance: Current Status and Future Perspectives. AB - Purpose of review: The use of donor apoptotic cells is an emerging therapy for inducing transplantation tolerance. In this review, we will discuss current understanding of mechanisms of this approach, as well as crucial aspects necessary for successful translation of this approach to clinical transplantation. Recent findings: Transplantation tolerance by donor apoptotic cells is mediated by their homeostatic interaction with recipient phagocytes, and subsequent expansion of suppressor cell populations as well as inhibition of effector T cells via deletion and anergy. To ensure their tolerogenicity, it is critical to procure non-stressed donor cells, and to induce and arrest their apoptosis at the appropriate stage prior to their administration. Equally important is the monitoring of dynamics of recipient immunological status, and its influences on tolerance efficacy and longevity. Emerging concepts and technologies may significantly streamline tolerogen manufacture and delivery of this approach, and smooth its transition to clinical application. Summary: Hijacking homeostatic clearance of donor apoptotic cells is a promising strategy for transplantation tolerance. Timing is now mature for concerted efforts for transitioning this strategy to clinical transplantation. PMID- 29177126 TI - Migrant female head porters' enrolment in and utilisation and renewal of the National Health Insurance Scheme in Kumasi, Ghana. AB - Purpose: As a social protection policy, Ghana's National Health Insurance Scheme (NHIS) aims to improve access to healthcare, especially for the vulnerable. Migrant female head porters (kayayoo), who are part of the informal economic workforce, are underscored as an ethnic minority and vulnerable group in Ghana. This study aimed to analyse the factors associated with enrolment in and renewal and utilisation of the NHIS among migrant female head porters in the Kumasi Metropolis. Method: We purposively sampled 392 migrant female head porters in the Kejetia, Asafo and Bantama markets. We used a binary logit regression model to estimate associations among baseline characteristics, convenience and benefit factors and enrolment in and renewal and utilisation of the NHIS. Result: Age and income significantly increased the probability of NHIS enrolment, renewal and utilisation. Long waiting times at NHIS offices significantly reduced the likelihood of renewal, while provision of drugs highly significantly increased the tendency for migrant female head porters to enrol in, renew and use the NHIS. Consulting and surgery also significantly increased renewal and utilisation of the NHIS. Conclusion: Political commitment is imperative for effective implementation of the decentralisation policy of the NHIS through the National Health Insurance Authority in Kumasi. We argue that retail offices should be well equipped with logistic facilities to ensure convenience in NHIS initial enrolment and renewal processes by citizenry, and by vulnerable groups in particular. PMID- 29177127 TI - Different healthy habits between northern and southern Spanish school children. AB - Aim: Healthy habits are influenced by several factors such as geographical location. The aims of this study were to describe and compare healthy habits within two populations of sixth-grade primary school children (aged 11-12 years) from northern and southern Spain. Subjects and methods: A cross-sectional study using two representative samples of school children was conducted. Participants came from Logrono (n = 329) in the north and Granada (n = 284) in the south of Spain. Socio-demographic and anthropometric variables, adherence to the Mediterranean diet, aerobic fitness, and healthy lifestyles were recorded. Results: Boys reported a higher level of physical activity and aerobic fitness than girls (p = 0.000). Southern school children reported significantly higher adherence to the Mediterranean diet (?: p = 0.041; ?: p = 0.008), lower aerobic fitness (?: p = 0.000; ?: p = 0.042) and hours of nightly sleep (?: p = 0.008, ?: p = 0.007) than northern school children. Southern boys also reported lower levels of physical activity (p = 0.013). There were slight or moderate correlations among all habits measured (physical activity, diet, screen and sleep time). Additionally, the physical activity level was inversely related to weight status. Overweight and obese northern boys reported less physical activity than healthy-weight northern boys (p = 0.020) and overweight and obese southern girls reported less physical activity than healthy-weight southern girls (p = 0.024). Conclusions: Results showed differences in physical activity, eating and sleep habits, and aerobic fitness according to geographical location. The relationships found among lifestyle habits indicate the need for health promotion interventions nationally and considering the differences discussed here. PMID- 29177128 TI - Playground usage and physical activity levels of children based on playground spatial features. AB - Aim: Being outdoors is one of the strongest correlates of physical activity in children. Playgrounds are spaces especially designed to enable and foster physical activity in children. This study aimed to analyze the relationship between the spatial features of public playgrounds and the usage and physical activity levels of children playing in them. Subjects and methods: A quantitative, observational study was conducted of ten playgrounds in one district of a middle-sized town in Germany. Playground spatial features were captured using an audit instrument and the playground manual of the town. Playground usage and physical activity levels of children were assessed using a modified version of the System for Observing Play and Leisure Activity in Youth. Negative binomial models were used to analyze the count data. Results: The number of children using the playgrounds and the number of children actively playing in them were higher in those with more varied facilities and without naturalness. Girls played more actively in playgrounds without multi-purpose areas. Cleanliness, esthetics, play facility quality, division of functional areas and playground size were not related to any outcome variable. Conclusion: Playground spatial features are related to playground usage and activity levels of the children in the playgrounds. Playgrounds should offer a wide variety of play facilities and provide spaces for diverse play activities to respond to the needs of large numbers of different children and to provide activity-friendly areas enabling their healthy development. PMID- 29177130 TI - Sleep Disordered Breathing and Spinal Cord Injury: Challenges and Opportunities. AB - Purpose of review: This paper focuses on the sleep disorders in patients with spinal cord injury (SCI/D), particularly mechanism of sleep disordered breathing (SDB) and challenges in diagnosis and management. Based on a review of recent literatures and studies the paper summarizes some main challenges with respect to management of SDB in patients with SCI; and what are the responsible mechanisms of disease? What are the barriers in diagnosing and treating SDB using standard treatment such as positive airway pressure (CPAP)?. Recent findings: Previous studies have shown that most SCI/D patients have SDB with heterogeneity in prevalence mainly related to using different definition or methods of diagnosing SDB, while recent studies using new definition of SDB based on recommended criteria from the American Academy of Sleep Medicine (AASM) and also include the data on effect of SCI/D level on prevalence and describe different type of SDB. Furthermore, recent data describes simplified method of diagnosing SDB by using a combination of home sleep apnea testing and transcutaneous CO2 monitoring. Finally, emerging data has been pointing at strong relationship between SDB and cardiovascular disease including nocturnal hypertension in patients with SCI/D. Summary: The findings indicate that early testing for SDB and associated cardiovascular disease in patients with SCI is recommended and could be beneficial in reduced the high morbidity and mortality in this group of patients with disability. In addition, studies on treatment of other sleep disorders in SCI/D are not available to inform clinical decision making. Understanding the pathophysiology of sleep disorders in SCI/D is critical for the development of new effective therapies. This review provides evidence for best practices; highlights new discoveries for the diagnosis and management of sleep disorders in SCI/D, and discuss challenges and future directions. PMID- 29177129 TI - SLEEP AND CIRCADIAN RHYTHM DISORDERS IN PARKINSON'S DISEASE. AB - Purpose of review: Sleep disorders are among the most challenging non-motor features of Parkinson's disease (PD) and significantly affect quality of life. Research in this field has gained recent interest among clinicians and scientists and is rapidly evolving. This review is dedicated to sleep and circadian dysfunction associated with PD. Recent findings: Most primary sleep disorders may co-exist with PD; majority of these disorders have unique features when expressed in the PD population. Summary: We discuss the specific considerations related to the common sleep problems in Parkinson's disease including insomnia, rapid eye movement sleep behavior disorder, restless legs syndrome, sleep disordered breathing, excessive daytime sleepiness and circadian rhythm disorders. Within each of these sleep disorders, we present updated definitions, epidemiology, etiology, diagnosis, clinical implications and management. Furthermore, areas of potential interest for further research are outlined. PMID- 29177131 TI - Recent Advances in Intestinal Stem Cells. AB - Purpose of review: The intestine is a dynamic organ with rapid stem cell division generating epithelial cells that mature and apoptose in 3-5 days. Rapid turnover maintains the epithelial barrier and homeostasis. Current insights on intestinal stem cells (ISCs) and their regulation are discussed here. Recent findings: The Lgr5+ ISCs maintain intestinal homeostasis by dividing asymmetrically, but also divide symmetrically to extinguish or replace ISCs. Following radiation or mucosal injury, reserve BMI1+ ISCs as well as other crypt cells can de differentiate into Lgr5+ ISCs. ISC niche cells, including Paneth, immune and myofibroblast cells secrete factors that regulate ISC proliferation. Finally, several studies indicate that the microbiome metabolites regulate ISC growth. Summary: ISC cells can be plastic and integrate a complexity of environmental/niche cues to trigger or suppress proliferation as needed. PMID- 29177133 TI - Integrin and FAK Regulation of Human Pluripotent Stem Cells. AB - Purpose of review: Human pluripotent stem cells (hPSCs) are anchorage-dependent cells that can be cultured on a variety of matrices and express integrins and the machinery for integrin signaling. Until recently, there has been limited understanding of exactly how integrin signaling regulates pluripotent stem cell (PSC) behavior. This review summarizes our knowledge of how integrins and focal adhesion kinase (FAK) regulate different aspects of hPSC biology. Recent findings: The latest research suggests that mouse and human embryonic stem cells utilize similar integrin signaling players but with different biological outcomes, reflecting the known developmental difference in their pluripotent status. Notably, attachment cues via FAK signaling are crucial for hPSCs survival and pluripotency maintenance. FAK may be found cortically but also in the nucleus of hPSCs intersecting core pluripotency networks. Summary: Integrins and FAK have been consigned to the conventional role of cell adhesion receptor systems in PSCs. This review highlights data indicating that they are firmly integrated in pluripotency circuits, with implications for both research PSC culture and scale up and use in clinical applications. PMID- 29177134 TI - Automatic Detection and Quantitative DCE-MRI Scoring of Prostate Cancer Aggressiveness. AB - Purpose: To develop a robust and clinically applicable automated method for analyzing Dynamic Contrast Enhanced (DCE-) MRI of the prostate as a guide for targeted biopsies and treatments. Materials and methods: An unsupervised pattern recognition (PR) method was used to analyze prostate DCE-MRI from 71 sequential radiotherapy patients. Identified regions of interest (ROIs) with increased perfusion were assigned either to the peripheral (PZ) or transition zone (TZ). Six quantitative features, associated with the washin and washout part of the weighted average DCE curve from the ROI, were calculated. The associations between the assigned DCE-scores and Gleason Score (GS) were investigated. A heatmap of tumor aggressiveness covering the entire prostate was generated and validated with histopathology from MRI-ultrasound fused (MRI-US) targeted biopsies. Results: The volumes of the PR-identified ROI's were significantly correlated with the highest GS from the biopsy session for each patient. Following normalization (and only after normalization) with gluteus maximus muscle's DCE signal, the quantitative features in PZ were significantly correlated with GS. These correlations straightened in subset of patients with available MRI-US biopsies when GS from the individual biopsies were used. Area under the receiver operating characteristics curve for discrimination between indolent vs aggressive cancer for the significant quantitative features reached 0.88-0.95. When DCE-scores were calculated in normal appearing tissues, the features were highly discriminative for cancer vs no cancer both in PZ and TZ. The generated heatmap of tumor aggressiveness coincided with the location and GS of the MRI-US biopsies. Conclusion: A quantitative approach for DCE-MRI analysis was developed. The resultant map of aggressiveness correlated well with tumor location and GS and is applicable for integration in radiotherapy/radiology imaging software for clinical translation. PMID- 29177132 TI - Autologous Cell Seeding in Tracheal Tissue Engineering. AB - Purpose of Review: There is no consensus on the best technology to be employed for tracheal replacement. One particularly promising approach is based upon tissue engineering and involves applying autologous cells to transplantable scaffolds. Here, we present the reported pre-clinical and clinical data exploring the various options for achieving such seeding. Recent Findings: Various cell combinations, delivery strategies, and outcome measures are described. Mesenchymal stem cells (MSCs) are the most widely employed cell type in tracheal bioengineering. Airway epithelial cell luminal seeding is also widely employed, alone or in combination with other cell types. Combinations have thus far shown the greatest promise. Chondrocytes may improve mechanical outcomes in pre clinical models, but have not been clinically tested. Rapid or pre vascularization of scaffolds is an important consideration. Overall, there are few published objective measures of post-seeding cell viability, survival, or overall efficacy. Summary: There is no clear consensus on the optimal cell scaffold combination and mechanisms for seeding. Systematic in vivo work is required to assess differences between tracheal grafts seeded with combinations of clinically deliverable cell types using objective outcome measures, including those for functionality and host immune response.

PMID- 29177135 TI - Quorum Sensing Down-Regulation Counteracts the Negative Impact of Pseudomonas aeruginosa on CFTR Channel Expression, Function and Rescue in Human Airway Epithelial Cells. AB - The function of cystic fibrosis transmembrane conductance regulator (CFTR) channels is crucial in human airways. However unfortunately, chronic Pseudomonas aeruginosa infection has been shown to impair CFTR proteins in non-CF airway epithelial cells (AEC) and to alter the efficiency of new treatments with CFTR modulators designed to correct the basic CFTR default in AEC from cystic fibrosis (CF) patients carrying the F508del mutation. Our aim was first to compare the effect of laboratory strains, clinical isolates, engineered and natural mutants to determine the role of the LasR quorum sensing system in CFTR impairment, and second, to test the efficiency of a quorum sensing inhibitor to counteract the deleterious impact of P. aeruginosa both on wt-CFTR and on the rescue of F508del CFTR by correctors. We first report that exoproducts from either the laboratory PAO1 strain or a clinical ?Early? isolate (from an early stage of infection) altered CFTR expression, localization and function in AEC expressing wt-CFTR. Genetic inactivation of the quorum-sensing LasR in PAO1 (PAO1DeltalasR) or in a natural clinical mutant (?Late? CF-adapted clinical isolate) abolished wt-CFTR impairment. PAO1 exoproducts also dampened F508del-CFTR rescue by VRT-325 or Vx 809 correctors in CF cells, whereas PAO1DeltalasR had no impact. Importantly, treatment of P. aeruginosa cultures with a quorum sensing inhibitor (HDMF) prevented the negative effect of P. aeruginosa exoproducts on wt-CFTR and preserved CFTR rescue by correctors in CF AEC. These findings indicate that LasR interfering strategies could be of benefits to counteract the deleterious effect of P. aeruginosa in infected patients. PMID- 29177137 TI - Obesity and obstructive sleep apnea risk among Nigerians. AB - Background: The contribution of obesity to obstructive sleep apnea (OSA) is poorly described in Nigeria. We aimed to compare OSA risk between obese and nonobese adults in urban Nigeria. Materials and Methods: An analytic cross sectional study was conducted. Participants were interviewed using the World Health Organization Non-Communicable Disease questionnaire. OSA risk assessment was performed using the STOP-BANG questionnaire. A total score of >=3 on the STOP BANG questionnaire indicated OSA risk, whereas a score >=5 indicated high OSA risk. Obesity was defined as body mass index (BMI) >30 kg/m2. Relationship between obesity and OSA was tested using chi-square and logistic regression models used to control for confounding factors. Results: There were 744 respondents, with a mean age of 44 (standard deviation 10) years. A total of 206 [27.7%, 95% confidence interval (CI) 24.46-30.9] respondents were obese (BMI >=30 kg/m2). A total of 307 (41.3%, 95% CI 37.7-44.9) respondents scored >=3 on the STOP-BANG questionnaire, whereas 37 (4.9%, 95% CI 3.6-6.7) scored >=5. More number of obese than nonobese [57.8% (119/206) versus 34.9% (188/538)] respondents met the criteria for OSA risk (P < 0.001). Similarly, more obese persons [10.3% (21/206)] met the criteria for high-risk OSA compared to the nonobese [3% (16/538)]; P < 0.001. In logistic regression models adjusted for cigarette smoking and alcohol consumption, the odds for OSA risk was 15.76 (95% CI 7.44-33.9) in persons with BMI >35 kg/m2 compared to those with a BMI range of 18.5-24.99. Conclusion: Obesity and OSA may be more prevalent in Nigeria than previously predicted. Obesity independently increased OSA risk in this population. PMID- 29177138 TI - Homology Modeling and Virtual Screening to Discover Potent Inhibitors Targeting the Imidazole Glycerophosphate Dehydratase Protein in Staphylococcus xylosus. AB - The imidazole glycerophosphate dehydratase (IGPD) protein is a therapeutic target for herbicide discovery. It is also regarded as a possible target in Staphylococcus xylosus (S. xylosus) for solving mastitis in the dairy cow. The 3D structure of IGPD protein is essential for discovering novel inhibitors during high-throughput virtual screening. However, to date, the 3D structure of IGPD protein of S. xylosus has not been solved. In this study, a series of computational techniques including homology modeling, Ramachandran Plots, and Verify 3D were performed in order to construct an appropriate 3D model of IGPD protein of S. xylosus. Nine hits were identified from 2,500 compounds by docking studies. Then, these nine compounds were first tested in vitro in S. xylosus biofilm formation using crystal violet staining. One of the potential compounds, baicalin was shown to significantly inhibit S. xylosus biofilm formation. Finally, the baicalin was further evaluated, which showed better inhibition of biofilm formation capability in S. xylosus by scanning electron microscopy. Hence, we have predicted the structure of IGPD protein of S. xylosus using computational techniques. We further discovered the IGPD protein was targeted by baicalin compound which inhibited the biofilm formation in S. xylosus. Our findings here would provide implications for the further development of novel IGPD inhibitors for the treatment of dairy mastitis. PMID- 29177139 TI - High Field In vivo13C Magnetic Resonance Spectroscopy of Brain by Random Radiofrequency Heteronuclear Decoupling and Data Undersampling. AB - In vivo13C magnetic resonance spectroscopy (MRS) is a unique and effective tool for studying dynamic human brain metabolism and the cycling of neurotransmitters. One of the major technical challenges for in vivo13C-MRS is the high radio frequency (RF) power necessary for heteronuclear decoupling. In the common practice of in vivo13C-MRS, alkanyl carbons are detected in the spectra range of 10-65 ppm. The amplitude of decoupling pulses has to be significantly greater than the large one-bond 1H-13C scalar coupling (1JCH = 125-145 Hz). Two main proton decoupling methods have been developed: broadband stochastic decoupling and coherent composite or adiabatic pulse decoupling (e.g., WALTZ); the latter is widely used because of its efficiency and superb performance under inhomogeneous B1 field. Because the RF power required for proton decoupling increases quadratically with field strength, in vivo13C-MRS using coherent decoupling is often limited to lowmagnetic fields [<=4 Tesla (T)] to keep the local and averaged specific absorption rate (SAR) under the safety guidelines established by the International Electrotechnical Commission (IEC) and the US Food and Drug Administration (FDA). Alternately, carboxylic/amide carbons are coupled to protons via weak long-range 1H-13C scalar couplings, which can be decoupled using low RF power broadband stochastic decoupling. Recently, the carboxylic/amide 13C MRS technique using low power random RF heteronuclear decoupling was safely applied to human brain studies at 7T. Here, we review the two major decoupling methods and the carboxylic/amide 13C-MRS with low power decoupling strategy. Further decreases in RF power deposition by frequency-domain windowing and time domain random under-sampling are also discussed. Low RF power decoupling opens the possibility of performing in vivo13C experiments of human brain at very high magnetic fields (such as 11.7T), where signal-to-noise ratio as well as spatial and temporal spectral resolution are more favorable than lower fields. PMID- 29177140 TI - Trichoscopy of Steroid-Induced Atrophy. AB - Intralesional corticosteroid (IL-CS) injections have been used to treat a variety of dermatological and nondermatological diseases. Although an important therapeutic tool in dermatology, a number of local side effects, including skin atrophy, have been reported following IL-CS injections. We recently noticed that a subset of patients with steroid-induced atrophy presented with ivory-colored areas under trichoscopy. We performed a retrospective analysis of trichoscopic images and medical records from patients presenting ivory-colored areas associated with atrophic scalp lesions. In this paper, we associate this feature with the presence of steroid deposits in the dermis and report additional trichoscopic features of steroid-induced atrophy on the scalp, such as prominent blood vessels and visualization of hair bulbs. PMID- 29177141 TI - A Case of Circumscribed Scalp Morphea with Perineural Lymphocytes on Pathology. AB - Scalp morphea presents as a scarring alopecia in en coup du sabre pattern. We report an unusual presentation of a round hairless patch of morphea on the occipital scalp present for 15 years. The scalp lesion aligned with 2 other hyperpigmented lesions of biopsy-proven morphea in the lower back. Pathology of horizontal sections from the scalp lesion showed follicular dropout, thickening of the collagen bundles, and preserved eccrine and follicular structures. Marked lymphocytic perineural infiltrate, a reported clue to the diagnosis of scalp morphea, contributed to the diagnosis. This case is unusual due to its rare clinical presentation. It also highlights the importance of recognizing histopathological clues for the diagnosis of uncommon scalp disorders.

AB - Congenital curved nail of the fourth toe represents an unusual deformity in which the nail of the fourth toe curves in a plantar direction. It is unknown why only this toe is affected; however, the initial descriptions suggest that this is a mesodermal defect. We describe a case of congenital curved nail of the fourth toe associated with bifid uvula. There are only 2 reports mentioning the association of this nail abnormality with cleft palate and/or lip. In our patient, there was an association with bifid uvula that is considered a minor form of palatine fissure. There seems to be an association of congenital curved nail of the fourth toe with cleft palate to different degrees; however, the pathogenesis of the deformity remains unknown.

PMID- 29177146 TI - Patchy Frontal Fibrosing Alopecia: Description of an Incomplete Clinical Presentation. AB - We describe 6 incomplete cases of frontal fibrosing alopecia (FFA). All patients were postmenopausal women. Their average age was 60 years; 2 of the women were Caucasian, and the remaining 4 women were of a mixed ethnicity. The disease duration ranged from 3 to 17 years. The patients' lesions presented as irregular alopecic plaques in the frontal and/or temporal regions, with few signs of perifollicular inflammation, slow progression, and progressive loss of the vellus hair in the frontal area. Loss of the eyebrows, facial hyperpigmentation, and loss of the body hair were observed in 3 patients, 1 patient, and 2 patients, respectively. Localized pruritus and dysesthesia were reported in 5 patients and 3 patients, respectively. Dermatoscopic examination indicated the absence of viable ostia at the centers and edges of the lesions and the absence of peripilar erythema; moreover, peripilar hyperkeratosis was less intense than it would be expected in classical cases of lichen planopilaris (LPP) and FFA. Histological examination revealed that all cases featured the presence of a perifollicular lichenoid infiltrate in the infundibulum and isthmus as well as concentric areas of fibrosis. All samples were subjected to direct immunofluorescence (DIF), which produced negative results. FFA has been recently diagnosed and is considered a subtype of LPP. FFA can present with incomplete clinical manifestations, a histology similar to LPP, and negative DIF findings. The correct diagnosis of FFA associated lesions is critical for providing appropriate treatment, developing prognostic definitions, and excluding other types of scarring and nonscarring alopecia. The diagnosis of incomplete FFA is essential to avoid diagnostic and therapeutic errors. PMID- 29177147 TI - Exogen Hairs in Women with and without Hair Loss. AB - Contrary to the classical view of the hair cycle, in which telogen is the resting phase that precedes the release of the hair shaft, another phase has been introduced, exogen. Exogen is the phase wherein the processes for the release of the hair shaft are initiated and successfully executed. Exogen ends when the shaft is liberated. Accordingly, human hairs would be preferably released not with telogen but with exogen roots. To better understand this somehow revolutionary point and what occurs in telogen effluvium (TE) and in androgenetic alopecia (AGA), we undertook a morphological study. We examined 25 women of comparable age by collecting shedding hairs by the Modified Wash Test under stringent diagnostic criteria. Eight patients were "normal", 5 had AGA, 9 TE, and 3 had a TE+AGA overlap. Hair roots were divided into early telogen, full telogen, and exogen. Exogens accounted, in normal women, for 2.6% of all hairs, for 5.2% in AGA, for 6.6% in TE, and for 2.3% in TE+AGA, without any significant difference. Our exogen prevalence (2.6%) did not vary in patients with AGA and TE. Therefore, the pathogenetic role of exogen in AGA and TE seems negligible.

AB - Among childhood cancer survivors (CCSs), non-melanoma skin cancer (NMSC) is the most common type of second malignancy. Morbidity related to the development of NMSC in this group of patients may be sometimes unpredictable and difficult to manage. We present the case of a 49-year-old female who was a CCS and developed giant superficial basal cell carcinomas (sBCCs) over the previously irradiated field of the scalp. BCC involved the atrophic skin overlying the catheter of the peritoneal cerebral shunt that was set there for the management of hydrocephalus. Topical treatment with imiquimod 5% resulted in local skin reaction that was further complicated with catheter exposure. The patient underwent an emergency neurosurgery for reposition of the cerebral shunt. Subsequent treatment with imiquimod resulted in complete resolution of sBCC. Given the increased risk for the development of BCCs in CCSs, awareness of neurosurgeons is crucial. Avoidance of setting the catheter of the cerebral shunt within the radiotherapy field is highly recommended, in order to avoid unnecessary future surgeries and subsequent morbidity, as in our case. PMID- 29177148 TI - Descriptive Epidemiology of Hidradenitis Suppurativa in Greece: A Study of 152 Cases. AB - Background/Objective: Hidradenitis suppurativa (HS) is a chronic, inflammatory skin disease that remarkably affects the patients' quality of life. A prospective study of 152 HS patients was conducted in order to depict the clinico epidemiological characteristics of HS patients in Greece. Materials and Methods: From February 2015 to August 2016, 152 patients attended the Hidradenitis Suppurativa Outpatient Clinic of our department. The most important clinico epidemiological data of the patients were registered. Descriptive statistics and an ordered logistic regression analysis were performed. Results: Of the 152 patients, 60.5% were females. Their median age was 37 years. A total of 26.3% of the patients suffered from Hurley stage I, 44.7% from Hurley stage II, and 29.0% from Hurley stage III. The median duration of disease was 9 years. The most common site of involvement was the groins. The mean Dermatology Life Quality Index (DLQI) was higher for Hurley stage III. In multivariable analysis, only the body mass index was found to independently predict the disease severity. Conclusion: Among the factors examined, the body mass index appears to independently predict the disease severity. Quality of life evaluation revealed a stronger impact compared to the international experience. To our knowledge, this is the first descriptive epidemiological study among HS patients in Greece. PMID- 29177150 TI - Cutaneous Lupus Erythematosus Presenting as Frontal Fibrosing Alopecia: Report of 2 Patients. AB - Frontal fibrosing alopecia represents a peculiar condition with a quasi symmetrical, marginal scarring alopecia along the frontal and temporal hairline. The condition has been associated with further histopathologic and/or clinical evidence of lichen planopilaris. Since its emergence with the original report of Kossard in 1994, frontal fibrosing alopecia has been recognized to be associated with a number of comorbidities, including lupus erythematosus. So far, respective case reports and case series have given account of frontal fibrosing alopecia with the histopathologic features of lichen planopilaris associated or overlapping with lupus erythematosus. In contrast, we present cases of histopathologically proven cutaneous lupus erythematosus presenting as frontal fibrosing alopecia with a good response to the respective treatment with oral hydroxychloroquine and/or intralesional triamcinolone acetonide. PMID- 29177151 TI - Blue-White Veil as Novel Dermatoscopic Feature in Discoid Lupus Erythematosus in 2 African-American Patients. AB - Dermoscopic features of discoid lupus erythematosus (DLE) depend on the stage of the lesions: active lesions include yellow-brown dots and red dots, whereas longstanding inactive lesions show absence of follicular openings, cicatricial milky red or white patches, structureless white and brown areas, and thick arborizing vessels. Loss of pinpoint white dots, blue-gray dots in a speckled pattern, and a peripheral pigmented network have been described on dermoscopy of DLE in dark skin. We report a blue-white veil as a novel dermoscopic feature in 2 cases of biopsy-proven DLE in African-American patients. Dry trichoscopy revealed a central white area surrounded by irregular patchy areas of confluent blue and brown pigment and an overlying white "ground-glass" hue. This corresponds on pathology to the hyperkeratosis overlying interface changes at the dermal epidermal junction, with pigment incontinence and melanophages in the papillary dermis. PMID- 29177152 TI - An Atypical Localized Form of Hidradenitis Suppurativa of the Jawline and Neck Mimicking Severe Cystic Acne on Presentation. AB - Hidradenitis suppurativa (HS) is a chronic and debilitating suppurative disease primarily affecting the axillae, perineum, and inframammary regions, where apocrine sweat glands are present. However, HS can occur in atypical locations. We present an interesting case of a 40-year-old man who developed chronic painful subcutaneous nodules, deep sinus tracts, and abscesses involving the jawline and the anterior aspect of the neck as the only parts of the body affected and who responded satisfactorily to adalimumab and laser hair removal treatment. This case is relevant because it helps clinicians to remember that HS may be isolated to atypical locations, such as the anterior aspect of the neck and chin. It also supports another possible HS pathogenesis which consists of the occlusion of terminal hair follicles rather than being essentially a disorder of the apocrine glands. PMID- 29177153 TI - Poliosis and Neurofibromatosis Type 1: Two Familiar Cases and Review of the Literature. AB - Two brothers were referred to our clinic for reevaluation of neurofibromatosis type 1 (NF1). Both brothers presented a peculiarity that is not so common in NF1: poliosis overlying plexiform neurofibromas on the scalp. Poliosis overlying plexiform neurofibromas is rarely reported in the literature. The peculiarity of our cases is the familiarity and the presence of poliosis in the same location. PMID- 29177154 TI - Syphilitic Alopecia: Case Reports and Trichoscopic Findings. AB - There has been a resurgence of syphilis in the last decade. Although alopecia is not a common manifestation of the disease, the "moth-eaten" pattern is considered patognomonic. However, diffuse hair loss, termed essential alopecia, sometimes can be the only sign of syphilis infection and mimic other conditions, such as alopecia areata and telogen effluvium. We describe three patients with syphilis in whom the pattern of alopecia was not typical. Although clinical, histopathological, and trichoscopic examinations may share some similar findings with other hair diseases, the inclusion of syphilis in the differential diagnosis of hair loss causes is fundamental to a correct screening and diagnosis. PMID- 29177155 TI - Novel de novo AVPR2 Variant in a Patient with Congenital Nephrogenic Diabetes Insipidus. AB - Early diagnosis and treatment of congenital nephrogenic diabetes insipidus (CNDI) are essential due to the risk of intellectual disability caused by repeated episodes of dehydration and rapid rehydration. Timely genetic testing for disease causing variants in the arginine vasopressin receptor 2 (AVPR2) gene is possible in at-risk newborns with a known family history of X-linked CNDI. In this study, a Swedish male with no family history was diagnosed with CNDI at 6 months of age during an episode of gastroenteritis. We analyzed the coding regions of AVPR2 by PCR and direct DNA sequencing and identified an 80-bp duplication in exon 2 (GenBank NM_000054.4; c.800_879dup) in the proband. This variant leads to a frameshift and introduces a stop codon four codons downstream (p.Ala294Profs*4). The variant gene product either succumbs to nonsense-mediated decay or is translated to a truncated nonfunctional vasopressin V2 receptor. This variant was absent in four unaffected family members, including his parents, as well as in 100 alleles from healthy controls, and is thus considered a novel de novo disease causing variant. Identification of the disease-causing variant facilitated precise diagnosis of CNDI in the proband. Furthermore, it allows future genetic counseling in the family. This case study highlights the importance of genetic testing in sporadic infant cases with CNDI that can occur due to de novo variants in AVPR2 or several generations of female transmission of the disease-causing variant. PMID- 29177156 TI - Risk Factors for Culling, Sales and Deaths in New Zealand Dairy Goat Herds, 2000 2009. AB - The aim of this study was to identify risk factors for culling, sales and deaths in intensively managed dairy goat herds in New Zealand. A data set provided by the New Zealand Dairy Goat Cooperative (n = 13,197 does) was analyzed using a Cox proportional hazard model. The outcome of interest was length of productive life (LPL), defined as the number of days from the date of second kidding to the date of removal from the herd or the date on which follow-up was terminated, whichever occurred first. Milk solids yield in the first lactation (MSL1) as a predictor of LPL was parameterized in the model as a penalized spline term. To account for MSL1 violating the proportional hazards assumption of the Cox model, LPL was divided into two intervals: T1 (less than or equal to 730 days from the date of second kidding) and T2 (greater than 730 days from the date of second kidding). MSL1 was then included in the model as a time-dependent covariate. A frailty term was included in the model to account for unmeasured, herd-level effects on LPL. During T1, the daily hazard of removal for does that produced 80 kg milk solids in the first lactation was 0.84 (95% CI 0.58-1.23) times the daily hazard of removal for does that produced 30 kg milk solids in the first lactation. During T2, the daily hazard of removal for does that produced 80 kg milk solids in the first lactation was 1.44 (95% CI 0.79-2.65) times the daily hazard of removal for does that produced 30 kg milk solids in the first lactation. We conclude that involuntary losses may be avoided if high MSL1 yielding does are preferentially managed from 2 years beyond the date of second kidding. PMID- 29177157 TI - Odds Ratio or Prevalence Ratio? An Overview of Reported Statistical Methods and Appropriateness of Interpretations in Cross-sectional Studies with Dichotomous Outcomes in Veterinary Medicine. AB - One of the most commonly observational study designs employed in veterinary is the cross-sectional study with binary outcomes. To measure an association with exposure, the use of prevalence ratios (PR) or odds ratios (OR) are possible. In human epidemiology, much has been discussed about the use of the OR exclusively for case-control studies and some authors reported that there is no good justification for fitting logistic regression when the prevalence of the disease is high, in which OR overestimate the PR. Nonetheless, interpretation of OR is difficult since confusing between risk and odds can lead to incorrect quantitative interpretation of data such as "the risk is X times greater," commonly reported in studies that use OR. The aims of this study were (1) to review articles with cross-sectional designs to assess the statistical method used and the appropriateness of the interpretation of the estimated measure of association and (2) to illustrate the use of alternative statistical methods that estimate PR directly. An overview of statistical methods and its interpretation using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted and included a diverse set of peer-reviewed journals among the veterinary science field using PubMed as the search engine. From each article, the statistical method used and the appropriateness of the interpretation of the estimated measure of association were registered. Additionally, four alternative models for logistic regression that estimate directly PR were tested using our own dataset from a cross-sectional study on bovine viral diarrhea virus. The initial search strategy found 62 articles, in which 6 articles were excluded and therefore 56 studies were used for the overall analysis. The review showed that independent of the level of prevalence reported, 96% of articles employed logistic regression, thus estimating the OR. Results of the multivariate models indicated that logistic regression was the method that most overestimated the PR. The findings of this study indicate that although there are methods that directly estimate PR, many studies in veterinary science do not use these methods and misinterpret the OR estimated by the logistic regression.

PMID- 29177159 TI - Neuroendocrine Tumors of the Gastrointestinal Tract. PMID- 29177160 TI - Neuroendocrine Neoplasms: Dichotomy, Origin and Classifications. AB - Neuroendocrine neoplasms (NENs) are heterogeneous tumors with a common phenotype. There are two fundamentally different groups of NENs: well-differentiated, low proliferating NENs, called neuroendocrine tumors (NETs) or carcinoids, and poorly differentiated, highly proliferating NENs, called small- or large-cell neuroendocrine carcinomas (NECs). This NEN dichotomy is probably due to an origin from different neuroendocrine progenitor cells. The current World Health Organization (WHO) classification of gastrointestinal NENs uses the Ki67 proliferation index to grade NETs as G1 or G2, and NECs as G3. In the pancreas, NETs and NECs may overlap in their proliferation index, making the distinction between them difficult and leading to therapeutic uncertainties. Therefore, the WHO classification of pancreatic NENs (PanNENs) from 2017 introduced a new NET G3 category. Helpful for the distinction of NETs G3 from NECs is the expression of p53 and rb1 that is usually negative in PanNETs. Comparison of the WHO classification of digestive system NENs with other NEN classifications reveals site-specific differences in terminology and a general lack of grading systems. However, all classifications recognize the existence of the two major NEN families and provide a general basis for their prognostic and therapeutic stratification. A development of a common NEN classification across organs is desirable. PMID- 29177162 TI - Surgical Treatment of Small Intestinal Neuroendocrine Tumors G1/G2. AB - Although the majority of neuroendocrine tumors of the small intestine (siNETs) classified as low-grade G1 or G2 show slow local growth, they are frequently diagnosed at an advanced stage of metastatic disease. The surgical treatment is curative in stages I-III or palliative in stage IV in an attempt to avoid local complications of bowel obstruction and ischemia of the small bowel by unremoved lymph node metastases. Individualized surgical procedures performed by experienced surgeons considering tumor multifocality and the primary extent of lymph node metastases along the mesenteric vessels are recommended to remove as much tumor volume as possible, while avoiding major complications intraoperatively and small bowel syndrome postoperatively. PMID- 29177161 TI - Early Gastroenteropancreatic Neuroendocrine Tumors: Endoscopic Therapy and Surveillance. AB - Neuroendocrine neoplasias (NEN) of the stomach, duodenum, pancreas, appendix, or rectum that are <=1 cm in size as well as well-differentiated with World Health Organization grade 1 (G1) can be considered 'early' neuroendocrine tumors; they have a very good prognosis. Regarding prognosis, neuroendocrine tumors (NET) G1 must be distinguished from well-differentiated NET G2 and poorly differentiated neuroendocrine carcinomas (NEC) G3. NET are increasing, with a rise in the age adjusted incidence in the USA by about 700% in the last 40 years. Earlier diagnosis of NET is one of the main epidemiological changes of clinically detected NEN. The general availability of high-resolution endoscopy and advanced radiological imaging techniques has contributed to a shift in the discovery to smaller-sized (<=10 mm) gastrointestinal and pancreatic NET and earlier tumor stages at diagnosis. Thus, screening colonoscopy is effective in the early diagnosis not only of colorectal adenomas and adenocarcinomas but also of rectal NET. Endoscopic resection is the treatment of choice in NET G1 of the stomach, duodenum (despite gastrinoma), and rectum that are <=10 mm in size, do not infiltrate the muscularis propria (T1), and do not show angioinvasion (V0, L0). Similarly, histologically proven, early pancreatic NET G1 (<=10 mm) may be managed conservatively by regular surveillance. In contrast, small (<=1 cm) NET G1 of the jejunum or ileum are not 'early' tumors and have to be resected surgically with lymph node dissection. PMID- 29177163 TI - Surgical Therapy of Sporadic Pancreatic Neuroendocrine Neoplasias G1/G2. AB - Background: Pancreatic neuroendocrine neoplasias (pNENs) are uncommon but fascinating tumors with an annual incidence of 1 per 100,000 people. pNENs present either as functional tumors, causing specific hormonal syndromes like Zollinger-Ellison syndrome (ZES) or organic hyperinsulinism, or as non-functional pancreatic tumors (NF-pNENs). The natural history of pNENs is highly variable. 90% of all insulinomas or small NF- pNENs are readily curable by surgical resection. Most other functional and late detected NF-pNENs have a less favorable chance for cure. Methods: A systematic review of the literature was performed to identify the current state of the art with regard to the key issues of surgery in pNEN G1/G2. Results: This article provides a comprehensive review of the current literature addressing the current challenges in pNEN surgery. Conclusion: Patients with completely resected tumors generally have a good prognosis, and an aggressive surgical approach combined with conservative treatment options in patients with advanced disease rarely provides cure but often results in long term survival. PMID- 29177164 TI - Medical Therapy of Gastrointestinal Neuroendocrine Tumors. AB - Intestinal neuroendocrine tumors (NETs) constitute a heterogeneous group with duodenal, small intestinal, colonic and rectal NETs. They constitute more than half of all NETs, with the highest frequencies in the rectum, small intestine, and colon. The tumor biology varies with the location of the primary tumor as well as with the grade and staging of the tumor. Small intestinal NETs usually present low proliferation and are treated in the first line with somatostatin analogs according to current guidelines. If progression occurs, one can add interferon alpha or change the treatment to everolimus. Peptide receptor radionuclide therapy (PRRT) with Lutetium177-DOTATATE can be an option in the future after registration of the compound. Rectal tumors are usually small when they metastasize; they can be treated with somatostatin analogs but more so with PRRT, while another option is of course everolimus. Colonic NETs are more aggressive than the rest of intestinal NETs and will be treated with everolimus, sometimes in combination with somatostatin analogs based on positive scintigraphy. Another option is a cytotoxic agent such as streptozotocin plus 5 fluorouracil (5-FU) or temozolomide plus capecitabine. The most aggressive tumors, i.e. neuroendocrine carcinoma G3, are treated with a platin-based therapy plus etoposide; if they present with a lower proliferation, i.e. <50%, temozolomide plus capecitabine plus bevacizumab can also be attempted. Duodenal NETs are mostly treated similar to pancreatic NETs, either with cytotoxic agents, streptozotocin plus 5-FU, or temozolomide plus capecitabine, or with targeted agents such as everolimus. PMID- 29177166 TI - Neuroendocrine Tumors of the Gastrointestinal Tract. PMID- 29177165 TI - Theranostics of Neuroendocrine Tumors. AB - Somatostatin receptor positron emission tomography/computed tomography using 68Ga labeled somatostatin analogs is the mainstay for the evaluation of receptor status in neuroendocrine tumors (NETs). This translates towards better therapy options, with increasing evidence of peptide receptor radionuclide therapy (PRRT) as the treatment of choice for advanced or progressive NETs. There are benefits in progression-free and overall survival as well as a significant improvement in clinical condition. In patients with progressive NETs, fractionated, personalized PRRT results in good therapeutic responses with no significant severe hematological and/or renal toxicity, thus improving quality of life. PMID- 29177167 TI - Impact of Body Mass Index on Early Postoperative and Long-Term Outcome after Rectal Cancer Surgery. AB - Background: The aim of this study was to investigate the impact of obesity and underweight onto early postoperative and long-term oncological outcome after surgery for rectal cancer. Methods: Data from 2008 until 2011 was gathered by a German prospective multicenter observational study. 62 items were reported by the physicians in charge, and a consecutive follow-up was performed if the patient had signed a consent form. Patients were subclassified into: underweight, normal weight, overweight, and obese - using the definitions of the World Health Organization. Results: In total, 9,920 patients were included, of whom 2.1% were underweight and 19.4% obese. The mean age was 68 years (range 21-99 years). Postoperative morbidity (mean 38.0%) was significantly increased in underweight and obese patients (p < 0.001). In-hospital mortality was 3.1% on average with no significant differences among patient groups (p = 0.176). The 5-year overall survival ranged between 36.9 and 61.3% and was worse in underweight and prolonged in overweight and obese patients compared to those with normal weight (p < 0.001 each). While the 5-year disease-free survival was increased in overweight and obese patients (p < 0.05 each), the 5-year local recurrence rate showed no correlation (p > 0.05 each). Multivariate analysis revealed that advanced age, higher ASA scoring, postoperative morbidity, and advanced tumor growth worsened the long-term survival independently. Conclusions: Underweight patients had a worse early and long-term outcome after rectal cancer surgery. Overweight and obesity were associated with a significantly better long-term survival. PMID- 29177169 TI - Local Administration of Methylprednisolone Laden Hydrogel Enhances Functional Recovery of Transected Sciatic Nerve in Rat. AB - Objective: To determine the effects of methylprednisolone-laden hydrogel loaded into a chitosan conduit on the functional recovery of peripheral nerve using a rat sciatic nerve regeneration model was assessed. Methods: 10-mm sciatic nerve defect was bridged using a chitosan conduit (CHIT/CGP-Hydrogel) filled with CGP hydrogel. In authograft group (AUTO) a segment of sciatic nerve was transected and reimplanted reversely. In methylprednisolone treated group (CHIT/MP) the conduit was filled with methylprednisolone-laden CGP-hydrogel. The regenerated fibers were studied within 16 weeks after surgery. Results: The behavioral, functional and electrophysiological studies confirmed faster recovery of the regenerated axons in methylprednisolone treated group compared to CHIT/Hydrogel group (p<0.05). The mean ratios of gastrocnemius muscles weight were measured. There was statistically significant difference between the muscle weight ratios of CHIT/MP and CHIT/Hydrogel groups (p<0.05). Morphometric indices of regenerated fibers showed number and diameter of the myelinated fibers were significantly higher in CHIT/MP than in CHIT/Hydrogel group. Conclusion: Methylprednisolone laden hydrogel when loaded in a chitosan conduit resulted in improvement of functional recovery and quantitative morphometric indices of sciatic nerve. PMID- 29177168 TI - Le Fort Fractures: A Collective Review. AB - Le Fort fractures constitute a pattern of complex facial injury that occurs secondary to blunt facial trauma. The most common mechanisms of injury for these fractures, which are frequently associated with drug and alcohol use, include motor vehicle collisions, assault, and falls. A thorough search of the world's literature following PRISMA guidelines was conducted through PubMed and EBSCO databases. Search terms included "Le Fort fracture", "facial", "craniofacial", and "intracranial." Articles were selected based on relevance and examined regarding etiology, epidemiology, diagnosis, treatment, complications, and outcomes in adults. The analyzed studies were published between 1980 and 2016. Initial data search yielded 186 results. The search was narrowed to exclude articles lacking in specificity for Le Fort fractures. Fifty-one articles were selected, the majority of which were large case studies, and collectively reported that Le Fort fractures are most commonly due to high-velocity MVC and that the severity of fracture type sustained occurred with increasing frequency. It was also found that there is a general lack of published Level I, Level II, and Level III studies regarding Le Fort fracture management, surgical management, and outcomes. The limitation of this study, similar to all PRISMA-guided review articles, is the dependence on previously published research and availability of references as outlined in our methodology. While mortality rates for Le Fort fractures are low, these complex injuries seldom occur in isolation and are associated with other severe injuries to the head and neck. Quick and accurate diagnosis of Le Fort fractures and associated injuries is crucial to the successful management of blunt head trauma. PMID- 29177170 TI - Effects of Chitosan-Zinc Oxide Nanocomposite Conduit on Transected Sciatic Nerve: An Animal Model Study. AB - Objective: To determine the effects of chitosan-zinc oxide nanocomposite conduit on transected sciatic nerve in animal model of rat. Methods: Sixty male White Wistar rats were used in this study. A 10-mm sciatic nerve defect was bridged using a chitosan-zinc oxide nanocomposite conduit (CZON) filled with phosphate buffered saline. In chitosan group (CHIT) the chitosan conduit was filled with phosphate buffered saline solution. In sham-operated group (SHAM), sciatic nerve was exposed and manipulated. In transected group (TC), left sciatic nerve was transected and nerve cut ends were fixed in the adjacent muscle. The regenerated fibers were studied within 12 weeks after surgery. Results: The behavioral and functional tests confirmed faster recovery of the regenerated axons in CZON group compared to Chitosan group (p<0.05). The mean ratios of gastrocnemius muscles weight were measured. There was statistically significant difference between the muscle weight ratios of CZON and Chitosan groups (p<0.05). Morphometric indices of regenerated fibers showed number and diameter of the myelinated fibers were significantly higher in CZON than in Chitosan. In immuohistochemistry, the location of reactions to S-100 in CZON was clearly more positive than Chitosan group. Conclusion: Chitosan-zinc oxide nanocomposite conduit resulted in acceleration of functional recovery and quantitative morphometric indices of sciatic nerve. PMID- 29177172 TI - Outcome of Long Standing Ulno-Humeral Dislocation Managed by Open Reduction and Stabilization with V-Y Plasty; Our Experience. AB - Objective: To assess the outcome of long standing ulno-humeral dislocation managed by open reduction and stabilization with V-Y plasty. Methods: This cross sectional study included 14 patients with elbow dislocation that was more than 3 months without joint ankylosis, myositis ossificans or nerve injury. The surgical management not only included open reduction of the elbow joint, but also elongation of the triceps aponeurosis, collateral ligament repair along with the stabilization of the elbow joint. The results were analyzed using the Mayo Elbow score and the range of motion at 3 months and results were compared with the function of the patients elbows before surgery. Results: Among the 14 included patients, there were 9 men and 5 women. The mean age of the patients was 27.8+/ 8.3 years. The average ROM Increased from 37.0?+/-25.8? to 99.7?+/-23.3? of flexion in the postop followup. Whereas the extension lag changed from 15.5?+/ 14.6? to 19.6?+/-18.3? . The mean Mayo score increased from 47 in the preop period to 87 in the postop period. Conclusion: This results demonstrates that relative good function with a pretty low risk can be obtained when comparing the functional results after 3 months with preoperative status. Based on these results we recommend that neglected elbow dislocation should be managed by surgical intervention even if the dislocations are old. PMID- 29177171 TI - Grafting with Cryopreserved Amniotic Membrane versus Conservative Wound Care in Treatment of Pressure Ulcers: A Randomized Clinical Trial. AB - Objective: To compare the healing process of pressure ulcers treated with cryopreserved human amniotic membrane allograft and routine pressure ulcer care in our hospital. Methods: From January 2012 to December 2013, in a prospective randomized clinical trial (IRCT201612041335N2), 24 patients with second and third stage of pressure ulcers were enrolled in this study. All patients needed split thickness skin grafts for pressure ulcer-wound coverage. Selected patients had symmetric ulcers on both upper and lower extremities. The patients were randomly divided into two groups: amnion and control. In the amnion group, the ulcer was covered with cryopreserved amniotic membrane and in the control group it was treated with local Dilantin powder application. The duration and success rate of complete healing was compared between the two groups. Results: The study group was composed of 24 pressure ulcers in 24 patients (19 males and 5 females) with a mean age of 44+/-12.70 years. The demographic characteristics, ulcer area, and underlying diseases were similar in both groups. The early sign of response, such as decrease in wound discharge, was detected 12-14 days after biological dressing. Complete pressure ulcer healing occurred only in the amnion group (p< 0.001). Partial healing was significantly higher in the amnion group (p< 0.03). Healing time in this group was faster than that the control group (20 days versus 54 days). No major complication was recorded with amniotic membrane dressing. Conclusion: Cryopreserved amniotic membrane is an effective biologic dressing that promotes re-epithelialization in pressure ulcers. PMID- 29177173 TI - Functional Outcome of Resection versus Reconstruction in Mason II-III Radial Head Fractures; A Short-Term Prospective Study. AB - Objective: To compare the short-term functional outcome between resection and reconstruction in Mason Type II and Type III radial head fractures using Broberg and Morrey score. Methods: A prospective cohort study was conducted in the Department of Orthopedic Surgery of SMS Medical College and attached Hospitals. A total of 29 patients (15 in resection group, 14 in reconstruction group) between the age group of 20-60 years with Mason Type II and Type III fresh closed radial head fractures were included in the study. The functional outcome including the range of motion, extension lag and Broberg Morrey score were determined and compared between two groups. Results: The mean age of resection group was 44.5 +/ 6.6 years and mean age of reconstruction group was 37.1 +/- 6.2 years. The baseline characteristics . At 12-months follow-up, in Mason type II fracture, radial head reconstruction group with mean extension lag of 9.4 +/- 4.1 and mean Broberg Morrey score of 94.9 +/- 5.1 showed better results compared to radial head resection group with mean extension lag of 15.7 +/- 4.1 (p=0.022) and mean Broberg Morrey score 88.3 +/- 5.1 (p=0.045) respectively. In Mason type III fractures, radial head resection with mean supination of 79.4 +/- 4.7, mean pronation of 74.4 +/- 4.1 and mean Broberg Morrey score of 89.8 +/- 6 showed better results when compared with radial head reconstruction group with mean supination of 64.2 +/- 4 (p<0.001), mean pronation of 59.2 +/- 8.4 (p=0.003) and mean Broberg Morrey score of 81.9 +/- 5 (p=0.031). Conclusion: The procedure suggested in Mason type II, is reconstruction of radial head. In Mason type III due to difficulty in achieving anatomical reduction results were not good with reconstruction when compared with resection. We recommend radial head excision in Mason type III fractures where anatomical and stable fixation is not possible.

AB - Objective: To epidemiologically assess the accidents and incidents in the injured pedestrians referred to Shahid Rajaee Hospital, Shiraz in order to provide basic preventive strategies and reduce injuries and fatalities caused by traffic accidents in pedestrians. Methods: This cross-sectional study was conducted on 5840 injured pedestrians referred to Shahid Rajaee Hospital, Shiraz from 2009 to 2014. The baseline characteristic including the demographic and clinical information, the mechanism of injury, injury severity score (ISS) and outcome determinants. We also recorded the outcome measures and the mortality. Multivariate logistic regression analysis was performed to investigate the factors related to mortality rate and Length of Stay (LOS) in hospital. Results: In our study, the history of 5840 injured pedestrians was analyzed. The mean age of the patients was 41.32 +/- 19.21 years. Multivariate logistic regression indicated that mortality increased with age. Moreover, the odds of mortality was more in patients with Injury Severity Score (ISS) between 16 and 24 [OR: 12.94, 95% CI (3.78-32.66), p=0.001] and injuries in the head and neck [OR: 7.92, 95% CI (4.18-14.99), p=0.020]. LOS in hospital was also higher in patients with ISS > 25 [OR: 16.65, 95%CI (10.68-25.96), p=0.001]. Conclusion: Pedestrians have always been one of the most vulnerable road users. Our study indicated that the adverse consequences and mortalities in pedestrians increased with age. Hence, approaches are required to improve primary prevention programs and reduce deaths and injuries due to this major public health problem. PMID- 29177175 TI - Domestic Injuries among Children Under 7 Years of Age in Iran; The Baseline Results from the Iranian First Registry. AB - Objective: To investigate epidemiological aspects of injuries among Iranian children under 7 years of age using obtained data from a national registry. Methods: Injury data were derived from a national-based injury supervision system during 2000-2002. This registry involved all of home-related injuries for children less than 7 years of age that treated in health or emergency centers. The study population included 25% of Iranian people. The descriptive statistical methods were used for representing the distribution of the variables like age, sex, injury mechanisms, types of injuries, etc. Data were presented as mean +/- SD and proportions as appropriate. Results: Of the total 307,064 domestic injuries registered during 2000-2002, 77,500 cases (25.2%) were children. 70% of these children (54581 cases) were in age group of 1-5 years. The large fraction (58.8%) of injuries among children under 7 years of age went back to burn injuries. Cuts and lacerations were at the second level with 17.4%. 51% of injuries had contact with hot liquids. Of all children under 7 years of age injuries, 282 died, 86 were disabled, while the rest improved or being under treatment when recording data. Conclusion: Injuries, particularly burns (especially those who had contact with hot liquids that led into scald), are major public health problem that children under 7 years of age encounter. Therefore, it seems necessary to provide adequate plans to promote children under 7 years of age safety issues. PMID- 29177176 TI - The Belief and Attitude of the Drivers Toward the Usage of Cellphone while Driving; A Population-Based Survey. AB - Objective: To presents a survey investigating differences between drivers' beliefs regarding utilizing cellphone when driving. Methods: In this population based survey, the participants who were studied in the North of Iran, Gorgan, were categorized as main urban and rural areas. A sample of 400 drivers, 92 women and 308 men, filled out the four sections questionnaire which was based on the Theory of Planned Behavior (TPB) used for measuring the differences between the drivers' opinions (attitudinal beliefs, normative beliefs, and perceived control behavioral beliefs) about utilizing a cell phone when driving along with their age and driving purpose. Data were collected by distributing the 68- query questionnaire between the drivers. Results: The MANOVA analysis showed that important discrepancies were found between the normative, control and behavioral beliefs of cellular phone users while driving. As expected, frequent business and younger users with sturdy intention expressed more benefits of further concentration on family members and fewer obstacles that would prevent them from utilizing cellphone when driving than older and frequently personal users. Conclusion: These results indicated that the benefits of utilizing cellphone while driving are greater than its dangers. To reduce cellphone utilization when driving and increase road safety, more effort is required to lower the perceived advantages of the behavior and to outstand the risks of this hazardous driving act. PMID- 29177177 TI - Does Intradisciplinary Conflict Influence to Outcomes of Emergency Medicine Residency Program? A Mixed Methods Study. AB - Objective: To explore impact of emergency medicine residency program on patient waiting times in emergency department (ED) and determine the associated factors. Methods: A two-phased sequential exploratory mixed-methods approach was used. The first phase was comprised of retrospective before-after design of ED encounters for a 3-month period, six months before and six months after the introduction of an emergency medicine residency program in an Iranian teaching hospital. The second phase included semi-structured interviews with five individuals which purposively selected to participate in qualitative design. Quantitative data were analysed descriptively and qualitative data were analysed using an iterative framework approach. Results: The most patients were admitted to the hospital in night shift, both before and after the resident EMS. No statistically significant differences were found among all of the waiting times during the two time periods except for the average time interval between admission and physician start time (p<0.0001), which increased (instead of reducing), and the average time interval between physician start time and first treatment measure (p<0.0001), which decreased during the year the residents began. The interviewees revealed the intradisciplinary conflicts and interferences existing between ED and other specialist departments, are main important factor to delayed processing of patients visits. Conclusion: This study has shown that intradisciplinary conflict would affect the outcomes of emergency medicine residency program and ED process. These new findings enhance the understanding of the nature of conflicts and will persuade policy makers that design a set of clinical practice guidelines to clarify the duties and responsibilities of parties involved in ED. PMID- 29177178 TI - Factors Affecting the Location of Road Emergency Bases in Iran Using Analytical Hierarchy Process (AHP). AB - Objective: To identify and prioritize factors affecting the location of road emergency bases in Iran using Analytical Hierarchy Process (AHP). Methods: This was a mixed method (quantitative-qualitative) study conducted in 2016. The participants in this study included the professionals and experts in the field of pre-hospital and road emergency services issues working in the Health Deputy of Iran Ministry of Health and Medical Education, which were selected using purposive sampling method. In this study at first, the factors affecting the location of road emergency bases in Iran were identified using literature review and conducting interviews with the experts. Then, the identified factors were scored and prioritized using the studied professionals and experts' viewpoints through using the analytic hierarchy process (AHP) technique and its related pair wise questionnaire. The collected data were analyzed using MAXQDA 10.0 software to analyze the answers given to the open question and Expert Choice 10.0 software to determine the weights and priorities of the identified factors. Results: The results showed that eight factors were effective in locating the road emergency bases in Iran from the viewpoints of the studied professionals and experts in the field of pre-hospital and road emergency services issues, including respectively distance from the next base, region population, topography and geographical situation of the region, the volume of road traffic, the existence of amenities such as water, electricity, gas, etc. and proximity to the village, accident prone sites, University ownership of the base site, and proximity to toll-house. Conclusion: Among the eight factors which were effective in locating the road emergency bases from the studied professionals and experts' perspectives, "distance from the next base" and "region population" were respectively the most important ones which had great differences with other factors. PMID- 29177179 TI - Endovascular Management of a Penetrating Zone III Retroperitoneal Gunshot Wound Injury; A Case Report. AB - Traumatic iliac vessels injuries secondary to gunshot wound can often be fatal at the scene. One of the intriguing complications of vascular injuries is arteriovenous fistula. If the patient survives, these lesions may often not be diagnosed on first evaluation and patients may present with clinical signs and symptoms years later. Open surgical repair can have prohibitive morbidity and mortality and endovascular techniques, an effective treatment alternative, can interrupt the abnormal vascular communication and preserve artery vein patency. We describe a unique case of iliac arteriovenous fistula (AVF), secondary to a bullet injury, identified by imaging studies and subsequently treated with endovascular surgery. In conclusion, traumatic AVF are rare. Traditional teaching mandates that zone III pelvic retroperitoneal hematomas secondary to penetrating trauma be explored. PMID- 29177180 TI - Isolated Traumatic Brachialis Muscle Tear: A Case Report and Review of Literature. AB - Isolated traumatic brachialis muscle tears are uncommonly reported - leading to occasional misdiagnosis and misdirected treatment. The rarity of brachialis muscle tear may promote misdiagnosis or mistreatment of this injury. We report an isolated brachialis muscle tear in a young female, possibly caused by strenuous exercise in the gymnasium. The diagnosis was made clinically and confirmed by magnetic resonance imaging. The patient was subsequently managed adequately with conservative treatment. We herein present a 35-year-old woman who was diagnosed with an acute brachialis muscle tear being diagnosed with a combination of clinical signs and imaging and successfully managed non-operatively. A chronologically arranged review of literature is also presented. PMID- 29177181 TI - Transient Diabetes Insipidus Following Thermal Burn; A Case Report and Literature Review. AB - Diabetes insipidus is a disease charaterised by increased urine production and thrist. Neurogenic diabetes insipidus following head trauma,autoimmune disease and infection is quite common but diabetes insipidus following thermal burn injury is a rare complication.We should know about this complication as its management need a comprehensive approach for satisfactory outcome. Thermal burn can cause different complications in early post burn period like electrolyte imbalance, dehydration, acute renal failure, but diabetes insipidus is a very rare and unusual complication that may come across in thermal burn. We should be aware about this condition to prevent and treat mortality and morbidity in burn patients. We have reported a case of transient diabetes insipidus in a patient of thermal burn in early post burn period. Patient was treated accordingly, leading to complete recovery. PMID- 29177182 TI - Glaucoma surgery and induced astigmatism: a systematic review. AB - Background: The refractive outcomes of glaucoma surgeries, particularly their effect on astigmatism, are incompletely understood. Main body: Trabeculectomy is associated with a considerable amount of with-the-rule astigmatic change in the immediate postoperative period. This is followed by a gradual against-the-rule shift. These changes are altered with the use of mitomycin C (MMC). Non penetrating surgery such as deep sclerectomy is also associated with a similar or smaller degree of induced astigmatism. Minimally invasive glaucoma surgery appears to be astigmatically neutral. There is no clear evidence regarding refractive outcomes of glaucoma drainage device surgery. Conclusions: Induced astigmatism may account for a reduction in unaided visual acuity in the early postoperative period following a successful trabeculectomy. These changes appear to stabilise at 3 months, and it would be prudent to defer the prescription of new glasses until this time. If sequential cataract surgery is to be performed, toric intraocular lenses can be a useful option for astigmatic correction. PMID- 29177183 TI - Molecular dynamics simulations in drug delivery research: Calcium chelation of G3.5 PAMAM dendrimers. AB - Poly(amido amine) (PAMAM) dendrimers have been considered as possible delivery systems for anticancer drugs. One potential advantage of these carriers would be their use in oral formulations, which will require absorption in the intestinal lumen. This may require the opening of tight junctions which may be enabled by reducing the Ca2+ concentration in the intestinal lumen, which has been shown as an absorption mechanism for EDTA (ethylenediaminetetraacetic acid). Using molecular dynamics simulations, we show that the G3.5 PAMAM dendrimers are able to chelate Ca2+ at similar proportions to EDTA, providing support to the hypothesis that oral formulations of PAMAM dendrimers could use this high chelating efficiency as a potential mechanism for permeating the tight junctions of the intestines if other formulation barriers could be overcome. PMID- 29177184 TI - Overrepresentation Analyses of Differentially Expressed Genes in the Smut Fungus Ustilago bromivora during Saprophytic and in planta Growth. AB - We have established the Ustilago bromivora-Brachypodium spp. interaction as a new model pathosystem for biotrophic fungal plant infections of the head smut type (Rabe et al., 2016). In this protocol, the methodology used for comparing gene expression between saprophytic and in planta growth of the fungus is described. The experimental and analytical pipeline, how next generation RNA sequencing (Illumina RNA-Seq) analysis can be used to obtain lists of genes significantly up or down regulated in planta in comparison to axenic culture is given. Furthermore, different methods to identify functional categories that are over- or under-represented among specific classes of genes are presented. PMID- 29177185 TI - A Murine Orthotopic Allograft to Model Prostate Cancer Growth and Metastasis. AB - Prostate cancer is one of the most common cancers in men in the United States. Comprehensive understanding of the biology contributing to prostate cancer will have important clinical implications. Animal models have greatly impacted our knowledge of disease and will continue to be a valuable resource for future studies. Herein, we describe a detailed protocol for the orthotopic engraftment of a murine prostate cancer cell line (Myc-CaP) into the anterior prostate of an immune competent mouse. PMID- 29177186 TI - Assessment of Murine Retinal Function by Electroretinography. AB - The electroretinogram (ERG) is a sensitive and noninvasive method for testing retinal function. In this protocol, we describe a method for performing ERGs in mice. Contact lenses on the mouse cornea measure the electrical response to a light stimulus of photoreceptors and downstream retinal cells, and the collected data are analyzed to evaluate retinal function. PMID- 29177187 TI - Increasing Research Productivity and Professional Development in Psychology With a Writing Retreat. AB - Writing is a core feature of the training requirements and career demands of psychology faculty members and graduate students. Within academic psychology, specifically, writing is vital for the generation of scientific knowledge through manuscripts and grant applications. Although resources exist regarding how to improve one's writing skills, few models have been described regarding how to promote a culture of writing productivity that realizes tangible deliverables, such as manuscripts and grant applications. In this article, we discuss the rationale, model, and initial outcome data of a writing retreat developed and implemented to increase research productivity among psychology faculty and trainees. We also review best practices for conducting writing retreats and identify key areas for future SoTL on advancing writing. PMID- 29177189 TI - A Neural Signature Encoding Decisions under Perceptual Ambiguity. AB - People often make perceptual decisions with ambiguous information, but it remains unclear whether the brain has a common neural substrate that encodes various forms of perceptual ambiguity. Here, we used three types of perceptually ambiguous stimuli as well as task instructions to examine the neural basis for both stimulus-driven and task-driven perceptual ambiguity. We identified a neural signature, the late positive potential (LPP), that encoded a general form of stimulus-driven perceptual ambiguity. In addition to stimulus-driven ambiguity, the LPP was also modulated by ambiguity in task instructions. To further specify the functional role of the LPP and elucidate the relationship between stimulus ambiguity, behavioral response, and the LPP, we employed regression models and found that the LPP was specifically associated with response latency and confidence rating, suggesting that the LPP encoded decisions under perceptual ambiguity. Finally, direct behavioral ratings of stimulus and task ambiguity confirmed our neurophysiological findings, which could not be attributed to differences in eye movements either. Together, our findings argue for a common neural signature that encodes decisions under perceptual ambiguity but is subject to the modulation of task ambiguity. Our results represent an essential first step toward a complete neural understanding of human perceptual decision making. PMID- 29177188 TI - alpha-Synuclein-Dependent Calcium Entry Underlies Differential Sensitivity of Cultured SN and VTA Dopaminergic Neurons to a Parkinsonian Neurotoxin. AB - Parkinson's disease (PD) is a debilitating neurodegenerative disease characterized by a loss of dopaminergic neurons in the substantia nigra (SN). Although mitochondrial dysfunction and dysregulated alpha-synuclein (aSyn) expression are postulated to play a role in PD pathogenesis, it is still debated why neurons of the SN are targeted while neighboring dopaminergic neurons of the ventral tegmental area (VTA) are spared. Using electrochemical and imaging approaches, we investigated metabolic changes in cultured primary mouse midbrain dopaminergic neurons exposed to a parkinsonian neurotoxin, 1-methyl-4 phenylpyridinium (MPP+). We demonstrate that the higher level of neurotoxicity in SN than VTA neurons was due to SN neuron-specific toxin-induced increase in cytosolic dopamine (DA) and Ca2+, followed by an elevation of mitochondrial Ca2+, activation of nitric oxide synthase (NOS), and mitochondrial oxidation. The increase in cytosolic Ca2+ was not caused by MPP+-induced oxidative stress, but rather depended on the activity of both L-type calcium channels and aSyn expression, suggesting that these two established pathogenic factors in PD act in concert. PMID- 29177191 TI - Motherhood and the Wages of Women in Professional Occupations. AB - It is well established that mothers are paid less than childless women and that fathers tend to earn higher wages relative to childless men, but we do not know whether these findings apply to workers in all occupations. Using IPUMS and ACS data from 1980 and 2010, we examine the family wage gap for highly educated professionals, the most advantaged sector of the occupational distribution. Results indicate that the size of the negative wage differential for motherhood has declined over time in all professions. Moreover, in the traditionally male dominated professions of STEM, medicine, and law, women with children experience a positive wage differential, whereas their counterparts in female-dominated professions continue to experience a negative one. The positive differential for fatherhood has remained stable over time. These findings underscore the growing heterogeneity of women's experiences in combining work and family and raise important questions for further research. PMID- 29177190 TI - Functional germline variants as potential co-oncogenes. AB - Germline variants that affect the expression or function of proteins contribute to phenotypic variation in humans and likely determine individual characteristics and susceptibility to diseases including cancer. A number of high penetrance germline variants that increase cancer risk have been identified and studied, but germline functional polymorphisms are not typically considered in the context of cancer biology, where the focus is primarily on somatic mutations. Yet, there is evidence from familial cancers indicating that specific cancer subtypes tend to arise in carriers of high-risk germline variants (e.g., triple negative breast cancers in mutated BRCA carriers), which suggests that pre-existing germline variants may determine which complementary somatic driver mutations are needed to drive tumorigenesis. Recent genome sequencing studies of large breast cancer cohorts reported only a handful of highly recurrent driver mutations, suggesting that different oncogenic events drive individual cancers. Here, we propose that germline polymorphisms can function as oncogenic modifiers, or co-oncogenes, and these determine what complementary subsequent somatic events are required for full malignant transformation. Therefore, we propose that germline aberrations should be considered together with somatic mutations to determine what genes drive cancer and how they may be targeted. PMID- 29177192 TI - Protein chainmail variants in dsDNA viruses. AB - First discovered in bacteriophage HK97, biological chainmail is a highly stable system formed by concatenated protein rings. Each subunit of the ring contains the HK97-like fold, which is characterized by its submarine-like shape with a 5 stranded beta sheet in the axial (A) domain, spine helix in the peripheral (P) domain, and an extended (E) loop. HK97 capsid consists of covalently-linked copies of just one HK97-like fold protein and represents the most effective strategy to form highly stable chainmail needed for dsDNA genome encapsidation. Recently, near-atomic resolution structures enabled by cryo electron microscopy (cryoEM) have revealed a range of other, more complex variants of this strategy for constructing dsDNA viruses. The first strategy, exemplified by P22-like phages, is the attachment of an insertional (I) domain to the core 5-stranded beta sheet of the HK97-like fold. The atomic models of the Bordetella phage BPP-1 showcases an alternative topology of the classic HK97 topology of the HK97-like fold, as well as the second strategy for constructing stable capsids, where an auxiliary jellyroll protein dimer serves to cement the non-covalent chainmail formed by capsid protein subunits. The third strategy, found in lambda-like phages, uses auxiliary protein trimers to stabilize the underlying non-covalent chainmail near the 3-fold axis. Herpesviruses represent highly complex viruses that use a combination of these strategies, resulting in four-level hierarchical organization including a non-covalent chainmail formed by the HK97-like fold domain found in the floor region. A thorough understanding of these structures should help unlock the enigma of the emergence and evolution of dsDNA viruses and inform bioengineering efforts based on these viruses. PMID- 29177193 TI - Percutaneous Management of a Pyocystic Fistulizing Continent Urinary Diversion. AB - Background: Continent diversions have since been performed with increasing frequency since the 1950s, with some providers espousing the use of orthotopic diversions as being the new gold standard. However, patients must be counseled to take great care in the maintenance of their diversions because of complications such as metabolic abnormalities, pouch stones, and mucus retention. Case Report: A 21-year-old male with a history of posterior urethral valves underwent a continent catheterizable diversion as a child. He is undocumented and without health insurance and as a result unable to follow-up with an urologist for >10 years. He subsequently develops pyocystis with cutaneous fistulization and pouch stones necessitating percutaneous management. Conclusion: Patients may benefit greatly from a continent urinary diversion, however, selection must include patients who are able to maintain their pouch and follow-up with their providers to avoid major complications that may occur up to years following the procedure. PMID- 29177194 TI - Primary Upper Urinary Tract Small Cell Carcinoma: A Case Series and Literature Review. AB - Background: Primary upper urinary tract small cell carcinoma (SCC) is exceedingly rare with < 30 cases reported in the literature. Little is known about the incidence, diagnosis, treatment, and outcomes in these patients. We present a series of three patients with primary upper tract SCC. Case Presentation: Patient 1 is an 89-year-old Caucasian male who presented with hydroureteronephrosis and a mass in the proximal right ureter. Biopsy revealed SCC. Without further intervention, the patient died 2 months after his diagnosis. Patient 2 is a 67 year-old Caucasian female who underwent left laparoscopic nephroureterectomy for primary distal ureteral SCC, pT4N1M0. She developed lymphadenopathy and completed external beam radiation to the pelvis and four courses of cisplatin-based chemotherapy. She died from metastatic disease 7 months after diagnosis. Patient 3 is a 45-year-old female who underwent open right radical nephrectomy, retroperitoneal lymph node dissection, and hepatic metastasectomy for metastatic primary upper tract SCC, pT3N1M1. She underwent two subsequent retroperitoneal debulking procedures for recurrence followed by treatment with octreotide. She developed widespread metastasis and was treated with temozolomide and capecitabine before her death 80 months after diagnosis. Conclusion: This series contributes to the limited knowledge of the management and natural course of primary upper tract SCC. Patient 1 represents the first disease-specific mortality reported in a patient who received no therapy. Patient 3 represents the longest reported survival with metastatic disease, and the first treated with octreotide. The patient was managed with aggressive repeat surgical resection and exhibited 2 years of progression-free survival on octreotide. Emphasis should be placed on aggressive resection of all visible disease combined with the use of multimodal adjuvant chemoradiation for selected patients in this rare disease. PMID- 29177195 TI - Total Preperitoneal Robot-Assisted Kidney Transplantation. AB - To date, kidney transplant recipients have always undergone open surgery. The type and length of the wound vary, but most commonly, a modified Gibson's incision is made in the lower abdomen for the transplantation. Risk factors for wound complications are well defined in general surgery literature. The laparoscopic kidney transplantation (LKT) technique has been developed recently, and several teams have published studies on the intraperitoneal technique. In this case report, we present our technique of total preperitoneal LKT using the Da Vinci robotic surgical system. PMID- 29177196 TI - To Refer or Not to Refer: General Pediatricians' Perspectives on Their Role in Caring for Transgender Youth. AB - Little is known about general pediatricians' experience and knowledge regarding the care of transgender youth. We surveyed N=50 general pediatricians practicing in an integrated Midwest health system. Few respondents had participated in medical management care for transgender patients, but one-third were willing to do so if training opportunities were made available. Notably, <60% of respondents were comfortable providing routine care for transgender youth. At a minimum, pediatricians need the training to feel capable of providing routine care for transgender pediatric patients. In addition, opportunities for training should be offered to those who are willing to learn about medical management of transgender youth. PMID- 29177197 TI - Foam Sclerotherapy during Shunt Surgery for Portal Hypertension and Varices. AB - Objective: This preliminary study investigated the clinical safety and efficacy of foam sclerotherapy during shunt surgery to treat portal hypertension and gastroesophageal varices. Methods: Seven patients with confirmed portal hypertension and a variceal bleeding history underwent mesocaval shunt with simultaneous polidocanol foam injection into the varices. Computed tomography and endoscopic reviews were conducted within two weeks following the procedures and around six months later. Results: Six patients underwent side-to-side mesocaval shunt. One received a prosthetic mesocaval shunt. Polidocanol foam was injected into the gastric varices or the inferior mesenteric vein during the surgery. Surgical success and survival was achieved in all patients. Gastric ulcer formation and thrombocytopenia occurred in one patient respectively, which were ameliorated by conservative treatment. During 12 to 24 months' follow-up, three patients had obvious decrease or eradication of gastroesophageal varices; four patients had obvious decrease of gastric varices but residual esophageal varices; and all patents had unobstructed shunts. Encephalopathy occurred in one patient two months postoperatively. No sclerosant-related complications were observed and no postoperative recurrent variceal bleeding occurred. Conclusions: Foam sclerotherapy during shunt surgery is safe and effective for portal hypertension and varices treatment. PMID- 29177198 TI - Attention modulates perception of visual space. AB - Attention readily facilitates the detection and discrimination of objects, but it is not known whether it helps to form the vast volume of visual space that contains the objects and where actions are implemented. Conventional wisdom suggests not, given the effortless ease with which we perceive three-dimensional (3D) scenes on opening our eyes. Here, we show evidence to the contrary. In Experiment 1, the observer judged the location of a briefly presented target, placed either on the textured ground or ceiling surface. Judged location was more accurate for a target on the ground, provided that the ground was visible and that the observer directed attention to the lower visual field, not the upper field. This reveals that attention facilitates space perception with reference to the ground. Experiment 2 showed that judged location of a target in mid-air, with both ground and ceiling surfaces present, was more accurate when the observer directed their attention to the lower visual field; this indicates that the attention effect extends to visual space above the ground. These findings underscore the role of attention in anchoring visual orientation in space, which is arguably a primal event that enhances one's ability to interact with objects and surface layouts within the visual space. The fact that the effect of attention was contingent on the ground being visible suggests that our terrestrial visual system is best served by its ecological niche. PMID- 29177199 TI - Predicting tacrolimus concentrations in children receiving a heart transplant using a population pharmacokinetic model. AB - Objective: Immunosuppressant therapy plays a pivotal role in transplant success and longevity. Tacrolimus, a primary immunosuppressive agent, is well known to exhibit significant pharmacological interpatient and intrapatient variability. This variability necessitates the collection of serial trough concentrations to ensure that the drug remains within therapeutic range. The objective of this study was to build a population pharmacokinetic (PK) model and use it to determine the minimum number of trough samples needed to guide the prediction of an individual's future concentrations. Design setting and patients: Retrospective data from 48 children who received tacrolimus as inpatients at Primary Children's Hospital in Salt Lake City, Utah were included in the study. Data were collected within the first 6 weeks after heart transplant. Outcome measures: Data analysis used population PK modelling techniques in NONMEM. Predictive ability of the model was determined using median prediction error (MPE, a measure of bias) and median absolute prediction error (MAPE, a measure of accuracy). Of the 48 children in the study, 30 were used in the model building dataset, and 18 in the model validation dataset. Results: Concentrations ranged between 1.5 and 37.7 MUg/L across all collected data, with only 40% of those concentrations falling within the targeted concentration range (12 to 16 MUg/L). The final population PK model contained the impact of age (on volume), creatinine clearance (on elimination rate) and fluconazole use (on elimination rate) as covariates. Our analysis demonstrated that as few as three concentrations could be used to predict future concentrations, with negligible bias (MPE (95% CI)=0.10% (-2.9% to 3.7%)) and good accuracy (MAPE (95% CI)=24.1% (19.7% to 27.7%)). Conclusions: The use of PK in dose guidance has the potential to provide significant benefits to clinical care, including dose optimisation during the early stages of therapy, and the potential to limit the need for frequent drug monitoring. PMID- 29177200 TI - Spatial distribution of uranium in mice kidneys detected by laser ablation inductively coupled plasma mass spectrometry. AB - The aim of the study is to better understand where uranium deposits in mice kidneys. The spatial distribution of uranium was examined in the kidneys of C57BL/6 mice using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Mice were exposed to varying levels of uranyl nitrate in their drinking water. Calibration standards were developed to allow for semi quantitative measurement of uranium in the cortical and medullary regions of mice kidney by LA-ICP-MS. Scanning electron microscopy was used to image the ablation patterns on the kidney. Uranium levels were observed to increase in kidney tissue as uranyl nitrate treatment exposure levels increased. A trend towards a higher uranium concentration in the medullary versus cortical region of the kidneys was observed. These results show the usefulness of LA-ICP-MS in toxicity studies by providing a quantitative, spatial assessment of uranium deposition in a target organ. PMID- 29177201 TI - In Situ Visualization for 3D Agent-Based Vocal Fold Inflammation and Repair Simulation. AB - A fast and insightful visualization is essential in modeling biological system behaviors and understanding underlying inter-cellular mechanisms. High fidelity models produce billions of data points per time step, making in situ visualization techniques extremely desirable as they mitigate I/O bottlenecks and provide computational steering capability. In this work, we present a novel high performance scheme to couple in situ visualization with the simulation of the vocal fold inflammation and repair using little to no extra cost in execution time or computing resources. The visualization component is first optimized with an adaptive sampling scheme to accelerate the rendering process while maintaining the precision of the displayed visual results. Our software employs VirtualGL to perform visualization in situ. The scheme overlaps visualization and simulation, resulting in the optimal utilization of computing resources. This results in an in situ system biology simulation suite capable of remote simulation of 17 million biological cells and 1.2 billion chemical data points, remote visualization of the results, and delivery of visualized frames with aggregated statistics to remote clients in real-time. PMID- 29177202 TI - Applying physical science techniques and CERN technology to an unsolved problem in radiation treatment for cancer: the multidisciplinary 'VoxTox' research programme. AB - The VoxTox research programme has applied expertise from the physical sciences to the problem of radiotherapy toxicity, bringing together expertise from engineering, mathematics, high energy physics (including the Large Hadron Collider), medical physics and radiation oncology. In our initial cohort of 109 men treated with curative radiotherapy for prostate cancer, daily image guidance computed tomography (CT) scans have been used to calculate delivered dose to the rectum, as distinct from planned dose, using an automated approach. Clinical toxicity data have been collected, allowing us to address the hypothesis that delivered dose provides a better predictor of toxicity than planned dose. PMID- 29177203 TI - Modeling cancer rearrangement landscapes. AB - Cancer genome sequences contain footprints of somatic mutational processes, whose analysis in large tumor sequencing datasets has revealed novel mutational signatures, correlative features of variant topography, and complex events. Many of these analytic results have yet to reconciled with decades of mechanistic genome integrity research performed in controlled model systems. However, a new generation of genome-integrity experiments combining computational modeling, data analytics, and high-throughput sequencing are emerging to link mechanisms to patterns. Conversely, analytic studies evaluating quantitative footprints of specific genome integrity hypotheses will be critical in fitting naturally occurring mutational patterns to the predictions of a particular mechanistic model. Such quantitative and mechanistic studies will form the foundation of an emerging systems biology of genome integrity. PMID- 29177205 TI - New evidence for chemical fractionation of radioactive xenon precursors in fission chains. AB - Mass-spectrometric analyses of Xe released from acid-treated U ore reveal that apparent Xe fission yields significantly deviate from the normal values. The anomalous Xe structure is attributed to chemically fractionated fission (CFF), previously observed only in materials experienced neutron bursts. The least retentive CFF-Xe isotopes, 136Xe and 134Xe, typically escape in 2:1 proportion. Xe retained in the sample is complimentarily depleted in these isotopes. This nucleochemical process allows understanding of unexplained Xe isotopic structures in several geophysical environments, which include well gasses, ancient anorthosite, some mantle rocks, as well as terrestrial atmosphere. CFF is likely responsible for the isotopic difference in Xe in the Earth's and Martian atmospheres and it is capable of explaining the relationship between two major solar system Xe carriers: the Sun and phase-Q, found in meteorites. PMID- 29177204 TI - Nutritional Renaissance and Public Health Policy. AB - The science of nutrition has long been entrapped in reductionist interpretation of details, a source of great confusion. However, if nutrition is defined as the integration of countless nutrient factors, metabolic reactions and outcomes, biologically orchestrated as in symphony, its relevance for personal and public health would be less confusing and more productive. This more wholistic interpretation may be observed at the cellular and physiological levels and may be described, in part, by the concept of pleiotropy (multiple cell-based effects from one nutrient source), together with its more expansive cousin, epitropy (multiple cell-based effects from multiple nutrients). There are many consequences. First, wholistic interpretation helps to explain the profound but little-known health benefits of whole plant-based foods (not vegan or vegetarian) when compared with whole animal-based foods and/or with the nutritionally variable convenience foods (generally high in fat, salt, refined carbohydrates and low in complex carbohydrates). Second, wholistic interpretation explains why the U.S. Dietary Guidelines and related public policies, which are primarily conceived from reductionist reasoning, serve political agendas so effectively. If diet and health advisories were to acknowledge the biological complexity of nutrition, then make greater use of deductive (top down) instead of inductive (bottom up) reasoning, there would be less confusion. Third, wholistic nutrition, if acknowledged, could greatly help to resolve the highly-polarized, virtually intractable political debate on health care. And fourth, this definition tells why nutrition is rarely if ever offered in medical school training, is not one of the 130 or so medical specialties, and does not have a dedicated research institute at U.S. National Institutes of Health. Nutrition is a wholistic science whereas medical practice is reductionist, a serious mismatch that causes biased judgement of nutrition. But this dichotomy would not exist if the medical practice profession were to understand and adopt wholistic interpretation. Reductionist research, however, is crucially important because its findings provide the granular structure for wholistic interpretation-these two philosophies are inescapably interdependent. Evidence obtained in this manner lends strong support to the suggestion that nutrition is more efficacious and far more affordable in maintaining and restoring (treating) health than all the pills and procedures combined. Admittedly, this is a challenging paradigm for the domain of medical science itself. PMID- 29177206 TI - The Importance of Mammalogy, Infectious Disease Research, and Biosafety in the Field. AB - Large amounts of data and multitudes of publications have been independently generated by researchers in mammalogy and infectious diseases. The frequent confluence of these fields in epidemiological research as well as the facility of the data generated to be used in applied methods (e.g., conservation, public outreach, public health interventions) suggests that the intersection of these fields is important not only to their committed scientists but also to other areas of investigation, including public health. Given the increased frequency with which researchers in these fields interact with potentially infected humans, animals, and tissues, their occupations present a higher risk of exposure to a variety of pathogens than those in other fields of biology or among most jobs of the general public. However, a variety of methods are available for minimizing this risk, including increasing awareness of potential risks, using medical prophylaxes (when available), properly employing personal protective equipment, and using adequate disinfectants. Although instances of serious illness from zoonotic diseases among field researchers may be uncommon, they do occur; the purpose of this document is to increase awareness of risks that researchers principal investigators and students alike-face and highlight steps and resources that can mitigate those risks. PMID- 29177207 TI - Can pancreatic cancer behavior be predicted based on computed tomography measurements of fat and muscle mass? AB - : Many studies purport that obesity, and specifically visceral fat, impact survival after pancreaticoduodenectomy for pancreatic adenocarcinoma. However, these studies involve crude measures of obesity [eg, body mass index (BMI)] or visceral fat [eg, linear measurements on computed tomographic (CT) scans]. Some studies purport that weight loss and muscle wasting (ie, sarcopenia) presage poor survival in these patients. This study was undertaken to accurately measure and reexamine the impact of visceral fat, subcutaneous fat, and sarcopenia on pancreatic cancer. Materials and methods: CT scans of 100 patients undergoing pancreaticoduodenectomy for pancreatic adenocarcinoma were reviewed using specialized software to precisely determine the cross-sectional area (CSA) of subcutaneous fat, visceral fat, and psoas muscles at the level of L5 vertebra. In addition, linear measurements of subcutaneous fat and visceral fat were undertaken. Measures of cancer progression included tumor (T) status, nodal (N) status, American Joint Committee on Cancer stage, and overall survival after resection. Regression analysis was utilized, with and without standardization of all measurements to body size. Median data are presented. Results: The median patient age was 67 years, with a BMI of 24 kg/m2. Cancer stage was IIB for 60% of patients. BMI, CSA of visceral fat, CSA for subcutaneous fat, CSA for psoas muscles, and linear measurements of visceral and subcutaneous fat were not significantly related to any measures of cancer progression or survival. Standardization to body size did not demonstrate any relationships with cancer progression or survival. Conclusions: Precise and reproducible measures of visceral fat, subcutaneous fat, and muscle mass, even when standardized to body size, do not predict cancer progression or survival in patients undergoing pancreaticoduodenectomy for pancreatic adenocarcinoma. Pancreatic cancer biology and behavior is too complex to predict with a CT scanner. The main focus of pancreatic cancer research should continue to be at the molecular, genetic, and immunologic levels. PMID- 29177208 TI - Management of peritoneal surface malignancies in laparoscopic era: a concise review. AB - Peritoneal carcinomatosis is seldom curable. Maximal cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy has been used in efforts to improve survival. There has been a recent explosion of interest in this modality of treatment with various centers employing its use throughout the world. This is a complex procedure associated with significant morbidity and mortality. This makes patient selection very critical and hence there has been immense interest in the evaluation of various prognostic indicators being evaluated. In addition, with the advent of minimally invasive surgery, laparoscopy is being increasingly utilized in different capacity. Newer indications for treatment and possible prevention of peritoneal carcinomatosis are being evaluated especially in colorectal cancer. The aim of this brief review is to synthesize and present the recent data available regarding the outcomes and evolving trends associated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. PMID- 29177209 TI - H. pylori infection and gastric cancer in Bangladesh: a case-control study. AB - Background: Like that of other Asian countries gastric cancer (GC) is also a leading cancer in Bangladesh and also a cause for cancer-related mortality. Infection with Helicobacter pylori (H. pylori) is the strongest recognized risk factor for gastric adenocarcinoma. The infection is also prevalent in common people. This case-control study was carried out to find an association between GC and H. pylori infection in the community. Materials and Methods: To evaluate association of H. pylori and carcinoma of stomach this study was conducted at National Institute of Cancer Research & Hospital, Dhaka from January 2013 to December 2014. H. pylori status was determined serologically by using H. pylori kit in the department of Biochemistry laboratory of Bangabandhu Sheikh Mujib Medical University. In total, 114 patients with GC and 520 patients not having GC were studied as controls. Logistic regression method was used to calculate the odds ratio. Results: Significantly more patients in the case group (86.8%) were found to be seropositive for H. pylori antigen in contrast to the control group (67.5%). All of the cases in the present study were in advanced stage. No significant association between H. pylori seropositivity and tumor location was found. It was noted that undifferentiated gastric carcinoma had slightly more association with H. pylori infection. Younger H. pylori-infected patients had been found to be at higher relative risk for GC than older patients. Conclusion: As there is a strong association found between GC and H. pylori infection special emphasis to eradicate H. pylori infection might reduce the incidence of this dreadly disease. PMID- 29177210 TI - Patients unfit for neoadjuvant therapy may still undergo resection of locally advanced esophageal or esophagogastric junctional cancer with acceptable oncological results. AB - : Neoadjuvant chemotherapy (NA) is routinely offered to patients undergoing resection for locally advanced (>=cT3Nx or cTxN+) esophageal or esophagogastric junctional (EGJ) cancer in the United Kingdom. Patients with comorbidity precluding the use of NA can be considered for resection yet the effect of omitting NA on survival is unclear. Methods: Retrospective review of prospectively collected clinical data from patients undergoing attempted curative therapy for >=cT3Nx or cTxN+ esophageal or EGJ (Siewert type I-III) cancer between 2001 and 2013. Results: NA was commenced in 289 patients and primarily comprised 2 cycles of cisplatin and 5-fluorouracil (264 patients, 91%). Surgery alone was planned for 82 patients with NA omitted due to comorbidity. Patients undergoing surgery alone were matched for clinical variables and stage with those undergoing NA but were significantly older (mean=8 y, P<0.001). NA was associated with an improved median overall survival of 28.7 months, compared with 20.9 months for patients undergoing surgery alone (P=0.008). Patients undergoing surgery alone had a 90-day postoperative mortality rate of 10% compared with 3% for those undergoing NA (P=0.011). In patients discharged postoperatively, the median overall survival benefit of NA was 2.7 months (P=0.048). Those 19% of patients experiencing a significant histologic response to NA demonstrated further improved survival. Conclusions: NA improves survival in patients undergoing resection for locally advanced esophageal or EGJ cancer; however, the median benefit is <3 months in patients discharged postoperatively. Patients precluded from NA achieve acceptable oncological results but experience a higher risk of perioperative mortality. PMID- 29177211 TI - Functional rehabilitation in advanced intraoral cancer. AB - : Modern treatment of advanced intraoral cancer involves multidisciplinary teams with use of complicated reconstructive techniques to provide improved survival with optimal rehabilitation. Mastication is an important part of this process, and it can be severely impaired by tumor ablation. Whether flap reconstruction is a determinant factor in dental rehabilitation is still in debate. Patients and methods: Thirty-five patients with advanced intraoral cancer were reviewed to determine dental rehabilitation of different reconstructive techniques. The patients were treated with a multidisciplinary team approach. The patients' demographics, primary treatment, reconstructive surgery, dental rehabilitation, and functional outcome were recorded and analyzed. Results: Nine patients had Stadium III disease, and 26 patients had stadium IV. Thirty-two patients (91.42%) received postoperative radiotherapy. Masticatory and dental functional rehabilitation of patients was very poor. Only 15 patients (42.86%) could eat a normal diet, whereas 18 patients (51.42%) could manage only soft diets, and 2 patients (5.72%) could only be fed with a liquid diet. Denture rehabilitation was even more frustrating and had a direct impact on masticatory rehabilitation. Only 10 patients (28.57%) could use dentures postoperatively and 40% of patients (14 patients) could not use any denture at all. Above all reconstructive techniques, the free radial forearm flap provides the best functional outcome. Conclusions: Reconstruction of advanced intraoral cancer results in poor denture rehabilitation, especially when bulky flaps are used. If massive resections are necessary, the free radial forearm flap reconstruction provides the best functional outcome. PMID- 29177212 TI - Spontaneous splenic artery rupture in a patient with an unclassified malignant spindle cell tumor of the spleen: report of a case. AB - The purpose of this paper was to describe an unusual manifestation of a sarcoma of the spleen and to raise awareness for spontaneous rupture of the splenic vessels in patients with splenic tumors. A 70-year-old man was admitted to our institution, suffering from left upper quadrant abdominal pain. Upon physical examination, a large and tender abdominal mass was palpated. Abdominal computed tomography showed a heterogenous enlarged spleen with active contrast extravasation from the splenic artery, free intraperitoneal fluid, and a retroperitoneal hematoma. The patient was treated with angioembolization of the splenic artery. Because of rebleeding, splenectomy was performed. Pathology revealed the spleen to be involved with an unclassified malignant spindle cell neoplasm. We concluded that in the case of spontaneous rupture of the splenic artery, accompanied with a radiologic appearance of an enlarged spleen, the diagnosis of sarcoma should be included in the differential diagnosis.

PMID- 29177213 TI - Sulfonylureas (not metformin) improve survival of patients with diabetes and resectable pancreatic adenocarcinoma. AB - : Patients with pancreatic adenocarcinoma have an increased propensity for diabetes. Recent studies suggest patients with diabetes and pancreatic adenocarcinoma treated with metformin have increased survival. This study was undertaken to determine whether metformin use is associated with increased survival in patients with pancreatic adenocarcinoma. Methods: Patients who underwent pancreaticoduodenectomy for pancreatic adenocarcinoma from 1991 to 2013 were included in this study. Survival was evaluated by Kaplan-Meier analysis. Median data are reported. Significance was accepted with 95% probability. Results: Of 414 patients undergoing pancreaticoduodenectomy for pancreatic adenocarcinoma, 132 (32%) were diabetic. Of patients with diabetes, 35 (27%) were diet-controlled, 34 (26%) were treated with insulin alone, 18 (14%) were treated with metformin alone, 14 (10%) were treated with sulfonylureas alone, 7 (5%) were taking sulfonylureas with insulin, and 24 (18%) patients were taking metformin with sulfonylureas and/or insulin. Patients with/without diabetes not taking sulfonylureas had survival of 16.4 months compared with patients taking sulfonylureas who achieved survival of 27.5 months after undergoing pancreaticoduodenectomy (P<0.05). Conclusions: Patients taking sulfonylureas with or without other therapy had improved survival compared with patients not taking sulfonylureas after pancreaticoduodenectomy. Metformin does not seem to be beneficial for patients with resectable disease, but may be beneficial for patients with unresectable and/or metastatic disease as shown in prior studies. The use of sulfonylureas is associated with a survival benefit for patients undergoing resection for pancreatic adenocarcinoma. Tumor staging and margin status continue to be the overriding predictors of survival in patients with resectable pancreatic adenocarcinoma, not metformin therapy.

PMID- 29177225 TI - The principles of the surgical management of gastric cancer. AB - Surgery is the only curative therapy for gastric cancer but most operable gastric cancer presents in a locally advanced stage characterized by tumor infiltration of the serosa or the presence of regional lymph node metastases. Surgery alone is no longer the standard treatment for locally advanced gastric cancer as the prognosis is markedly improved by perioperative chemotherapy. The decisive factor for optimum treatment is the multidisciplinary team specialized in gastric cancer. However, despite multimodal therapy and adequate surgery only 30% of gastric cancer patients are alive at 3 years. This article reviewed the principles of the surgical management of gastric cancer (minimally invasive or open) and how this may optimize multimodal treatment. PMID- 29177226 TI - Comparative effectiveness of laparoscopic versus open prostatectomy for men with low-risk prostate cancer: a matched case-control study. AB - : Little data exist on effect of undergoing laparoscopic prostatectomy(LP) versus open prostatectomy(OP) upon 30-day mortality rates among low-risk prostate cancer patients. Materials and methods: Using the National Cancer Database, we identified men (2004 to 2013) with biopsy-proven, low-risk prostate cancer who met the eligibility criteria: N0, M0, T-stage<=2A, PSA<=10 ng/mL, and Gleason score=6. We utilized a 1:N matched case-control study, with cases and controls matched by race, insurance status, Charlson-Deyo comorbidity score, surgical margin status, and facility type to investigate the short-term comparative effectiveness of LP versus OP. Results: Among the 448,773 patients in the National Cancer Database with low-risk prostate cancer, 116,359 patients met the above inclusion criteria. The target group was restricted to patients who received LP or OP, thus, leaving 44,720 patients for the study. The use of LP (compared with OP) was associated with patients with privately insured patients, treatment at an academic/research centers, high-volume hospitals, and white race (all P<0.01). LP was less frequently utilized for black patients, those who received treatment at community centers, and for those with Medicaid insurance(all P<0.01). The odds ratio of death for surgery type (laparoscopy vs. open) was estimated at 0.31 (95% confidence interval, 0.135-0.701; P<0.05). Thus, the risk of death within 30 days was 69% lower with LP compared with OP. Conclusions: We found that the 30-day mortality rate among low-risk prostate cancer patients is significantly lower among patients who received LP when compared with OP, with various clinicopathologic parameters associated with its preferential use.

AB - : Ward rounds permeate health care delivery worldwide and form an important daily activity within all hospitals. In this study, the daily morning ward round in plastic surgery was examined from a teleological and systems point of view. Methods: Data were gathered from the following sources to inform the systems analysis: patient interviews, staff interviews, direct observations of the ward round on multiple occasions, and through process mapping. Results: To better understand the ward and its layout, a schematic of it was developed. Following observations of the ward round and the way in which decisions are made on it, an IDEF0 map was developed. Three patients were invited to take part in the study. Three members of staff were interviewed. The overarching themes from the interviews related to aspects of communication which this paper details. Conclusions: This small-scale study demonstrates how the ward round as a process can be assessed, including product quality, process quality, the measurement and management of capacity, the role of standardization, the role and significance of bottlenecks, the key information flows, including the role of feedback, and the motivation and incentives of system participants and ideas for improvement generated.

PMID- 29177235 TI - Metastatic melanoma patients' sensitivity to ipilimumab cannot be predicted by tumor characteristics. AB - : Immune checkpoint inhibitors have dramatically changed the prognosis for patients with metastatic melanoma. However, not all patients respond to therapy and toxicities can be severe leaving need for reliable clinical predictive markers. Methods: We examined primary tumor characteristics including ulceration, BRAF mutation status, and Breslow depth in patients who subsequently developed stage IV disease and were treated with ipilimumab at 3 institutions. Patients in this study were not treated on clinical trials. To investigate the relationship between patient characteristics at the time of diagnosis and survival following melanoma diagnosis we utilized Cox proportional hazards models, accounting for delayed entry into the study cohort. Cox models estimate the age and institution adjusted hazard ratios for risk of death. Results: Of patients (n=385) treated with ipilimumab for stage IV melanoma, 302 met inclusion criteria. The complete response to ipilimumab was 5%, partial response was 13%, 18% had stable disease, 62% had progressive disease, and 5 unknown. The median overall survival rate was 2.03 years [95% confidence interval (CI): 0.13, 3.05]. Primary tumor Breslow depth, lymphovascular invasion, BRAF status, and ulceration did not predict sensitivity to ipilimumab. In this study patient cohort, BRAF mutation (adjusted hazard ratio: 1.43, 95% CI: 0.98, 2.07) and presence of ulceration (adjusted hazard ratio: 1.47, 95% CI: 0.95, 2.26) contributed to an increased risk of death. Conclusions: The presence of ulceration did not correlate with sensitivity to ipilimumab. Ulceration of the primary tumor and a BRAF mutation were moderately associated with worse survival in patients with metastatic melanoma treated with ipilimumab. PMID- 29177236 TI - A new strategy and system for the ex vivo ovary perfusion and cryopreservation: An innovation. AB - Children and young adults, who suffer from cancer, receive gonadotoxic therapy, which destroys their fertile abilities after survival. Ovarian cryopreservation and transplantation provide the promising solution to this problem, where the ovary can be removed before the gonadotoxic therapy and reimplanted after patient's survival, where the ovary is to be cryopreserved during the period of the therapy. However, cryopreservation of the whole ovary is still facing great obstacles, namely the ischemic reperfusion injury and the defective cryopreservation related to the defective ability to universally deliver the cryopreservation/warming solutions through the ovarian vascular bed. Meanwhile, the currently applied technique of ovarian tissue cryopreservation provides limited follicular recovery because many follicles are lost until the development of revascularization post-transplantation. To solve the problems, an innovative system has been developed to insure immediate and universal delivery of the cryopreservation/warming solutions to the graft, in addition to keeping the graft under continuous perfusion before and after cryopreservation, minimizing any chance for microthrombi formation or ischemia-reperfusion. This innovative system can be applied in the following surgical and clinical interventions: 1) Allogeneic ovarian transplantation; 2) Preservation of fertility after systemic chemotherapy or bone marrow transplantation in young females, where the ovaries could be removed before the therapy and exposed to the adequate cryopreservation provided by the system till re-implantation after the patient's survival; 3) The system is also suitable for the corresponding applications on the testicles. PMID- 29177238 TI - Comparing the effect of gonadotropin-releasing hormone agonist and human chorionic gonadotropin on final oocytes for ovulation triggering among infertile women undergoing intrauterine insemination: An RCT. AB - Background: The purpose of triggering in ovulation induction is to induce the final maturation of oocytes and their release from the ovary for fertilization. Objective: The aim of the present study was to compare the effectiveness of gonadotropin-releasing hormone (GnRH) agonist and human chorionic gonadotropin (HCG) on the final maturation of oocytes and pregnancy rates in intrauterine insemination (IUI) cycles. Materials and Methods: In this randomized clinical trial, 110 infertile women who were selected for IUI entered the study. Ovulation induction was performed. Group I received 0.1 mg GnRH agonist as triggering and group II received 10,000 IU of HCG. The serum E2, LH, and FSH levels were measured at 12 and 36 hr after injection. Results: LH surge was detected in all patients. LH levels at 12 and 36 hr after triggering was higher in Group I and it washed out earlier than group II (p=0.00). The pregnancy rate was higher in Group I, but the difference was not statistically significant (26.9% vs. 20.8%, respectively p=0.46). Also, the incidence of ovarian hyperstimulation syndrome was not different between the two groups (p=0.11). There was a significant difference regarding the estradiol levels at 36 hours after triggering (p=0.00). Conclusion: Effects of GnRH on endogenous LH surge is sufficient for oocyte releasing and final follicular maturation. Pregnancy rates and ovarian hyperstimulation syndrome incidence were not different between the groups. We suggest that GnRH agonists might be used as an alternative option instead of HCG in IUI cycles. PMID- 29177239 TI - Genital infections and reproductive complications associated with Trichomonas vaginalis, Neisseria gonorrhoeae, and Streptococcus agalactiae in women of Qom, central Iran. AB - Background: Trichomonas vaginalis (T.vaginalis) and Neisseria gonorrhoeae (N.gonorrhoeae) are two most common non-viral sexually transmitted infections in the world. No data are available regarding the epidemiology of genital infections in women of Qom, central Iran. Objective: Epidemiological investigation of sexually transmitted infections in genital specimens of women referred to the referral gynecology hospital in Qom, central Iran. Materials and Methods: Genital swab specimens were collected from women volunteers and used for identification of bacterial and protozoal infections by conventional microbial diagnostics, porA pseudo gene LightCycler(r) real-time PCR (for N.gonorrhoeae) and ITS-PCR (for T.vaginalis). Results: Of 420 volunteers, 277 (65.9%) had genital signs/symptoms, including 38.3% malodorous discharge, 37.9% dyspareunia, and 54.8% abdominal pain. Totally, 2 isolates of Streptococcus agalactiae were identified. Five specimens (1.2%) in Thayer-Martin culture and 17 (4.1%) in real-time PCR were identified as N.gonorrhoeae. Fifty-four specimens (12.9%) in wet mount, 64 (15.2%) in Dorset's culture, and 81 (19.3%) in ITS-PCR showed positive results for T.vaginalis. Five mixed infections of T.vaginalis+ N.gonorrhoeae were found. The risk of T.vaginalis infection was increased in women with low-birth-weight (p=0.00; OR=43.29), history of abortion (p=0.00; OR=91.84), and premature rupture of membranes (PROM) (p=0.00; OR=21.75). The probability of finding nuclear leukocytes (p=0.00; OR=43.34) in vaginal smear was higher in T.vaginalis infection. Conclusion: The significant prevalence of trichomoniasis and gonorrhea emphasizes the need for accurate diagnosis and effective surveillance to prevent serious reproductive complications in women. PMID- 29177240 TI - Polycystic ovary syndrome and circulating inflammatory markers. AB - Background: Human and experimental studies suggest that the sympathetic regulatory drive in the ovary may be unbalanced (hyperactivity) in polycystic ovary syndrome (PCOS). Dysfunctional secretion of interleukin (IL) -1 (alpha & beta) or related cytokines may thus be related to abnormal ovulation and luteinization. Objective: The aim of this study was the evaluation of cytokines' pattern in PCOS women and discussion about the explanation of cross-talk between two super systems: sympathetic and immune systems and explanation sympatho excitation and relationship with interleukins. Materials and Methods: In this study, 171 PCOS women aged between 20-40 years were studied the. Their body mass index was <28. The patients were divided into two groups: study group (n=85, PCOS women) and control group (n=86 normal women). The blood sample was obtained on the 3rd day of menstruation cycle. IL-17, IL-1alpha, IL-1beta, and TNF-alpha concentrations were determined in both groups. Results: The median serum level of IL-1alpha in the PCOS group was higher than the control group (293.3 and 8.0, respectively, p<0.001). Also, the median serum level of IL-1beta was higher than the control group (5.9 and 3.1 respectively). But the median serum of level IL-17 in women with PCOS was significantly lower than the control group (p<0.001). Conclusion: Our results confirm that PCOS is a low-level chronic inflammation. PMID- 29177237 TI - The etiologies of DNA abnormalities in male infertility: An assessment and review. AB - The sperm DNA damage may occur in testis, genital ducts, and also after ejaculation. Mechanisms altering chromatin remodeling are abortive apoptosis and oxidative stress resulting from reactive oxygen species. Three classifications of intratesticular, post-testicular, and external factors have been correlated with increased levels of human sperm DNA damage which can affect the potential of fertility. Lifestyle, environment, medical, and iatrogenic factors might be considered to cause dysmetabolism to make distracting interactions and endocrine disrupting compounds. As a result, these may induce chromatin/DNA alteration in germ cells, which may be transmitted across generations with phenotypic consequences. Alcohol consumption may not increase the rate of sperm residual histones and protamine deficiency; however, it causes an increase in the percentage of spermatozoa with DNA fragmentation and apoptosis. In a medical problem as spinal cord injury, poor semen parameters and sperm DNA damage were reported. Infection induces reactive oxygen species production, decreases the total antioxidant capacity and sperm DNA fragmentation or antigen production that lead to sperm dysfunctions and DNA fragmentation. While reactive oxygen species generation increases with age, oxidative stress may be responsible for the age dependent sperm DNA damage. The exposing of reproductive organs in older men to oxidative stress for a long time may produce more DNA-damaged spermatozoa than youngers. Examining the sperm chromatin quality in testicular cancer and Hodgkin's lymphoma patients prior to chemotherapy demonstrated the high incidence of DNA damage and low compaction in spermatozoa at the time of the diagnosis. In chemotherapy cycle with genotoxic agents in cancer patients, an increase in sperm DNA damage was shown after treatment. In overall, those factors occurring during the prenatal or the adult life alter the distribution of proteins associated with sperm chromatin induce changes in germ cells which can be detected in infertile patients.

AB - Background: Psychological interventions such as counseling for infertile patients seem to increase pregnancy rate. Objective: The aim of this systematic review and meta-analysis was to examine if counseling improves pregnancy rate among infertile patients. Thus, randomized controlled trials investigating the effect of counseling on pregnancy rate in infertile patients undergoing ART were pooled in a meta-analysis. Materials and Methods: The databases of PubMed, Scopus, Cochrane, Google Scholar, and Persian databases including SID, Iran Medex, and Magiran were searched from 1997 to July 2016 to identify relevant articles. Included studies were trials on infertile patients (women or couples) receiving counseling independent of actual medical treatment. The outcome measure was pregnancy rate. Out of 620 relevant published trials, a total of nine RCTs were ultimately reviewed systematically and included in a meta-analysis to measure the efficacy of counseling on pregnancy rate. Odds ratio and Risk difference were calculated for pregnancy rate. All statistical analyses were done by Comprehensive Meta-analysis Version 2. Results: Nine RCTs involving 1079 infertile women/couples were included in the study. The findings from RCTs indicated significant effect of counseling on pregnancy rate so that there was a positive impact of counseling on pregnancy rate (OR= 3.852; 95% CI: 2.492-5.956; p=0.00) and (RD= 0.282; 95%; CI: 0.208-0.355; p=0.00). Conclusion: Counseling was found to improve patients' chances of becoming pregnant. So counseling represents an attractive treatment option, in particular, for infertile patients who are not receiving medical treatments.

AB - Background: Prenatal drug exposure, as a common public health concern, is associated with an increased risk of adverse effects on early embryo development. Objective: To investigate the in vitro development of - embryo from experimentally Kerack-addicted mice. Materials and Methods: Twenty-five female mice were studied in five groups: control, vehicle, and three experimental groups of Kerack-dependent mice (I, II, and III) which received different doses of Kerack for 14 days. After the establishment of addiction model (7 days), experimental groups I, II, and III were given Kerack intraperitoneally at the doses of 5, 35, and 70 mg/kg, twice a day for a period of 7 days, respectively. The vehicle group received normal saline and lemon juice whilst the control group just received water and food. Morulae were obtained through oviduct flashing. The survived embryos were cultured in T6+ 5mg/ml bovine serum albumin. The developmental rates up to hatched stage daily and embryo quality (differential staining and Tunnel staining) were also assessed. Results: The developmental potential of embryos obtained from the addicted mother was significantly decreased in comparison with control group. There was a significant reduction in the rate of blastocyst formation in the high dose Kerack dependent group. However, in addicted mice there was reduction in the total cell number (40.92% vs. 65.08% in control) and, inner cell mass percentage (17.17% vs. 26.15% in control) while apoptotic cells numbers were increased (7.17 vs. 1.46 in control) (p<0.05). Conclusion: The Kerack addiction during pregnancy retards preimplantation development and induces apoptosis. PMID- 29177243 TI - Association of leptin and insulin resistance in PCOS: A case-controlled study. AB - Background: Endocrine abnormalities related to polycystic ovary Syndrome (PCOS) are important problems. Objective: To compare serum leptin levels between infertile women with and without PCOS. To rank sensitivity of six indirect methods for detection of insulin resistance (IR) and to evaluate the association between leptin and IR in PCOS group. Materials and methods: This Case-controlled study performed on 189 infertile women referred to Shiraz Mother and Child Hospital during 2012-2015. Ninety-nine PCOS cases according to Rotterdam criteria were compared to 90 cases without PCOS. Serum leptin, body mass index (BMI), several hormones, and their correlation coefficients with leptin were compared. IR in PCOS women was measured by indirect methods, including fasting blood sugar (FBS), fasting insulin (FI), glucose/insulin, homeostatic model assessment of insulin resistance (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), and MacAuley index. Association between IR and leptin was evaluated. Independent sample t-test and Pearson's test were used. Results: Infertile women with PCOS had higher BMI (26.47+/-3.62 vs. 24.82+/-5.18 kg/m2) and serum leptin levels (41.79+/-187.89 vs. 19.38+/-12.57 ng/mL). Leptin showed significant association with weight and BMI in both groups (p<0.001) and to age in non-PCOS group. HOMA-IR showed the highest rate of IR followed by FI and QUICKI methods. The mean leptin levels had positive association with IR assessed by HOMA-IR (p<0.001), QUICKI (p<0.001), FI (p=.002), and FBS (p=0.02). Conclusion: BMI and IR have positive association with serum leptin in PCOS infertile women. HOMA-IR followed by FI and QUICKI is the most sensitive test for detection of IR. PMID- 29177244 TI - Final follicular maturation by administration of GnRH agonist plus HCG versus HCG in normal responders in ART cycles: An RCT. AB - Background: Gonadotropin-releasing hormone agonists (GnRH-a) was increasingly used for triggering oocyte maturationfor the prevention of ovarian hyperstimulation syndrome. Studies suggest that GnRH-a might be used as a better trigger agent since it causes both Luteinizing hormone and follicle stimulating hormone release from a physiologic natural cycle. Objective: The aim of this study was to evaluate the effect of dual-triggering in assisted reproductive technology outcomes. Materials and Methods: 192 normal responder women aged <=42 years and 18< Body Mass Index <30 kg/m2 enrolled in this single-blind randomized controlled trial. All participants received antagonist protocol. For final triggering, women randomly were divided into two groups. Group, I was triggered by 6500 IU human chorionic gonadotropin (hCG) alone, and group II by 6500 IU hCG plus 0.2 mg of triptorelin. The implantation, chemical, clinical and ongoing pregnancy, and abortion rates were measured. Results: The mean of retrieved oocytes and obtained embryos were statistically higher in the dual-trigger group (group I), but the implantation and pregnancy rates were similar in two groups. Conclusion: The results of our study did not confirm the favorable effect of dual triggered oocyte maturation with a GnRH-a and a standard dosage of hCG as an effective strategy to optimize pregnancy outcome for normal responders in GnRH antagonist cycles. We think that this new concept requires more studies before becoming a universal controlled ovarian hyperstimulation protocol in in vitro fertilization practice. PMID- 29177245 TI - Controlled ovarian stimulation with r-FSH plus r-LH vs. HMG plus r-FSH in patients candidate for IVF/ICSI cycles: An RCT. AB - Background: Different combination of gonadotropin preparation has been introduced with no definite superiority of one over others in in vitro fertilization (IVF), but individualized regimens for each patient are needed. Objective: The aim of the present study was to investigate the effect of controlled ovarian stimulation with recombinant- follicle stimulating hormone (r-FSH) plus recombinant luteinizing hormone (rLH) versus human menopausal gonadotropin (HMG) plus r-FSH on fertility outcomes in IVF patients. Materials and Methods: This is a randomized clinical trial study that was performed from October 2014-April 2016 on 140 infertile patients with a set of inclusion criteria that referred to infertility clinics in Vali- asr and Gandhi Hospital in Tehran. The women were randomly divided into two treatment groups. The first group (n=70) received rFSH from the second day of cycle and was added HMG in 6th day and the 2nd group (n=70), received rFSH from the second day of cycle and was added recombinant-LH in 6th day. Then ovum Pick-Up and embryo transfer were performed. In this study, we assessed the outcomes such as; chemical and clinical pregnancy rate, live birth and abortion rate. Results: Number of follicles in ovaries, total number of oocytes or M2 oocytes and quality of fetuses has no significant differences between two groups (p>0.05). Total number of fetuses were significantly higher in patients who received rFSH + HMG (p=0.02). Fertility outcomes consisted of: live birth rate, chemical pregnancy and clinical pregnancy rate were higher in rFSH + HMG group in comparison to rFSH +r-LH group (p<0.05). Conclusion: It seems that in IVF patients, HMG + rFSH used for controlled ovarian hyperstimulation have better effects on fertility outcomes, but in order to verify the results, it is recommended to implement studies on more patients. PMID- 29177246 TI - The effect of 24 hours delay in oocyte maturation triggering in IVF/ICSI cycles with antagonist protocol and not-elevated progesterone: A randomized control trial. AB - Background: The best time of final oocyte maturation triggering in assisted reproduction technology protocols is unknown. This time always estimated by combined follicular size and blood progesterone level. Objective: The aim of this study was evaluation of the effect of delaying oocyte maturation triggering by 24 hr on the number of mature oocytes (MII) and other in vitro fertilization cycle characteristics in antagonist protocols with not-elevated progesterone (p <=1 ng/ml). Materials and Methods: All patients' candidate for assisted reproduction technology underwent controlled ovarian hyperstimulation by antagonist protocol. When at least 3 follicles with >=18 mm diameters were seen by vaginal ultrasonography; blood progesterone level was measured. The patients who had progesterone level <=1 ng/dl entered the study. The participants' randomizations were done and patients were divided into two groups. In the first group, final oocyte maturation was done by human chorionic gonadotropin at the same day, but in the second group, this was performed 24 hr later. Oocytes retrieval was done 36 hr after human chorionic gonadotropin trigger by transvaginal ultrasound guide. Results: Number of retrieved oocytes, mature oocytes (MII), fertilized oocytes (2PN), embryos formation, number of transferred embryos and embryos quality has not significant differences between two groups. Also, fertilization and implantation rate, chemical and clinical pregnancy did not differ between groups. Conclusion: Delaying of triggering oocyte maturation by 24 hr in antagonist protocol with not-elevated progesterone (progesterone <=1 ng/ml) have not beneficial nor harmful effect on the number of mature oocytes (MII) and other in vitro fertilization cycle characteristics. PMID- 29177247 TI - Protective effects of curcumin co-treatment in rats with establishing chronic variable stress on testis and reproductive hormones. AB - Background: Protracted and repeated exposure to chronic variable stress (CVS) may lead to reproductive dysfunction. It is a basic cause of male infertility. Curcumin (CUR) is an active fraction of turmeric that used in traditional Chinese medicine. CUR represents various pharmacological activities. Objective: The purpose of this study was to determining the effects of CUR on testis and testosterone, follicle stimulating hormone (FSH) and luteinizing hormone (LH) in rats with establishing chronic variable stress. Materials and Methods: Twenty-one adult male Sprague-Dawley rats were divided into three groups: 1) control, 2) CVS and 3) CVS+ CUR (100 mg/kg/day dissolved in 0.5 mL of olive oil). All of the animals in control, CVS, and CVS+CUR groups were sacrificed after 15 days. Testosterone, FSH, LH, and testis damage were evaluated. Results: Significant changes in the normal range of testosterone, FSH, LH serum levels and seminiferous tubule apoptotic cells were detected in CVS group compared to the control rats (p=0.02). These parameters changed to a less extent in CVS+CUR animals compared to the CVS rats (p=0.02). Conclusion: Our findings propose that curcumin might have curative potential on the reproductive system function and its impairment. It's regulated by stress and reproductive-related hormones. PMID- 29177248 TI - Detection of Norepinephrine in Whole Blood via Fast Scan Cyclic Voltammetry. AB - Bioelectronic Medicines is an emerging field that capitalizes on minimally invasive technology to stimulate the autonomic nervous system in order to evoke therapeutic biomolecular changes at the end-organ. The goal of Bioelectronic Medicines is to realize both 'precision and personalized' medicine. 'Precise' stimulation of neural circuitry creates biomolecular changes targeted exactly where needed to maximize therapeutic effects while minimizing off-target changes associated with side-effects. The therapy is then 'personalized' by utilizing implanted sensors to measure the biomolecular concentrations at, or near, the end organ of interest and continually adjusting therapy to account for patient specific biological changes throughout the day. To realize the promise of Bioelectronic Medicines, there is a need for minimally invasive, real-time measurement of biomarkers associated with the effects of autonomic nerve stimulation to be used for continuous titration of therapy. In this study we examine the feasibility of using fast scan cyclic voltammetry (FSCV) to measure norepinephrine levels, a neurochemical relevant to end-organ function, directly from blood. FSCV is a well-understood method for measuring electroactive neurochemicals in the central nervous system with high temporal and high spatial resolution that has yet to be adapted to the study of the autonomic nervous system. The results demonstrate that while detecting the electroactive neurochemical norepinephrine in blood is more challenging than obtaining the same FSCV measurements in a buffer solution due to biofouling of the electrode, it is feasible to utilize a minimally invasive FSCV electrode to obtain neurochemical measurements in blood. PMID- 29177250 TI - A Visual Analytics Approach to Understanding Care Process Variation and Conformance. AB - With greater pressures of providing high-quality care at lower cost due to a changing financial and policy environment, the ability to understand variations in care delivery and associated outcomes and act upon this understanding is of critical importance. Building on prior work in visualizing health-care event sequences and in collaboration with our clinical partner, we describe our process in developing a multiple, coordinated visualization system that helps identify and analyze care processes and their conformance to existing care guidelines. We demonstrate our system using data of 5,784 pediatric emergency department visits over a 13-month period for which asthma was the primary diagnosis. PMID- 29177249 TI - Smyd1C Mediates CD8 T Cell Death via Regulation of Bcl2-Mediated Restriction of outer Mitochondrial Membrane Integrity. AB - The SET and Mynd domain 1 (Smyd1) locus encodes three tissue-restricted isoforms. Two previously characterized isoforms, Smyd1A and Smyd1B, are heart and skeletal muscle-restricted histone methyl transferases. Here we report that a third, non catalytic isoform, Smyd1C, is expressed predominantly in activated CD8 T cells. While Smyd1C- deficient CD8 T cells undergo activation-induced apoptosis, neither of two classical mechanisms activation-induced cell death nor activated cell autonomous death are utilized. Instead, Smyd1C accumulates within both mitochondria and the immunological synapse where it associates with Bcl-2, FK506 Binding Protein 8/38 (FKBP38) and Calcineurin. This complex maintains Bcl-2 phosphorylation, enhanced mitochondrial localization, and restricted apoptosis of activated CD8 T cells. We suggest that CD8 T cell death is governed, in part, by Smyd1C regulation of Bcl2-mediated restriction of outer mitochondrial membrane integrity. PMID- 29177251 TI - A concurrent subtractive assembly approach for identification of disease associated sub-metagenomes. AB - Comparative analysis of metagenomes can be used to detect sub-metagenomes (species or gene sets) that are associated with specific phenotypes (e.g., host status). The typical workflow is to assemble and annotate metagenomic datasets individually or as a whole, followed by statistical tests to identify differentially abundant species/genes. We previously developed subtractive assembly (SA), a de novo assembly approach for comparative metagenomics that first detects differential reads that distinguish between two groups of metagenomes and then only assembles these reads. Application of SA to type 2 diabetes (T2D) microbiomes revealed new microbial genes associated with T2D. Here we further developed a Concurrent Subtractive Assembly (CoSA) approach, which uses a Wilcoxon rank-sum (WRS) test to detect k-mers that are differentially abundant between two groups of microbiomes (by contrast, SA only checks ratios of k-mer counts in one pooled sample versus the other). It then uses identified differential k-mers to extract reads that are likely sequenced from the sub metagenome with consistent abundance differences between the groups of microbiomes. Further, CoSA attempts to reduce the redundancy of reads (from abundant common species) by excluding reads containing abundant k-mers. Using simulated microbiome datasets and T2D datasets, we show that CoSA achieves strikingly better performance in detecting consistent changes than SA does, and it enables the detection and assembly of genomes and genes with minor abundance difference. A SVM classifier built upon the microbial genes detected by CoSA from the T2D datasets can accurately discriminates patients from healthy controls, with an AUC of 0.94 (10-fold cross-validation), and therefore these differential genes (207 genes) may serve as potential microbial marker genes for T2D. PMID- 29177252 TI - A volumetric conformal mapping approach for clustering white matter fibers in the brain. AB - The human brain may be considered as a genus-0 shape, topologically equivalent to a sphere. Various methods have been used in the past to transform the brain surface to that of a sphere using harmonic energy minimization methods used for cortical surface matching. However, very few methods have studied volumetric parameterization of the brain using a spherical embedding. Volumetric parameterization is typically used for complicated geometric problems like shape matching, morphing and isogeometric analysis. Using conformal mapping techniques, we can establish a bijective mapping between the brain and the topologically equivalent sphere. Our hypothesis is that shape analysis problems are simplified when the shape is defined in an intrinsic coordinate system. Our goal is to establish such a coordinate system for the brain. The efficacy of the method is demonstrated with a white matter clustering problem. Initial results show promise for future investigation in these parameterization technique and its application to other problems related to computational anatomy like registration and segmentation. PMID- 29177253 TI - AMP-B-SBL: An algorithm for clustered sparse signals using approximate message passing. AB - Recently, we proposed an algorithm for the single measurement vector problem where the underlying sparse signal has an unknown clustered pattern. The algorithm is essentially a sparse Bayesian learning (SBL) algorithm simplified via the approximate message passing (AMP) framework. Treating the cluster pattern is controlled via a knob that accounts for the amount of clumpiness in the solution. The parameter corresponding to the knob is learned using expectation maximization algorithm. In this paper, we provide further study by comparing the performance of our algorithm with other algorithms in terms of support recovery, mean-squared error, and an example in image reconstruction in a compressed sensing fashion. PMID- 29177254 TI - Semi-quantitative assessment of pulmonary arterial hypertension associated with congenital heart disease through myocardial perfusion imaging. AB - OBJECTIVE: The study aimed to use myocardial perfusion imaging (MPI) as a semi quantitative method to assess the clinical severity of pulmonary arterial hypertension (PAH) in patients with congenital heart disease (CHD). SUBJECTS AND METHODS: A total of 24 patients with PAH related to CHD (PAH-CHD) who received interventional or medical treatment were included. All patients underwent physical examination, cardiac function evaluation, biochemical test, echocardiography, right heart catheterization (RHC), and MPI with 99mTc methoxyisobutyl isonitrile (99mTc-MIBI) pre and 6 months post treatments. The correlation between MPI target/background (T/B) ratios and other variables were calculated. The receiver operating characteristic (ROC) curves were developed to evaluate the diagnostic value of T/B ratios. RESULTS: Most of the cardiac functional parameters, surplus pulse O2 (SPO2), biochemical values and right heart catheterization parameters were found significantly elevated after treatment (P<0.05). Pre-treatment MPI showed that T/B ratio had strong correlations with SPO2, Borg scale, cardiac output (CO), cardiac index (CI), right ventricular stroke volume (RV-SV), pulmonary artery pressure (PAP), total pulmonary resistance (TPR), total pulmonary resistance index (TPRI), pulmonary vascular resistance (PVR), and pulmonary vascular resistance index (PVRI). After 6 months treatment, the correlation between T/B ratios and most of these parameters measured were reduced. Receiver operating characteristics curves showed that the diagnostic performance of MPI T/B ratio in moderate/severe PAH patients was significant. The area under the curve (AUC) when measured pre treatment was 0.929 (P=0.002) and reduced to 0.800 (P=0.046) at post-treatment. CONCLUSION: Semi-quantitative MPI has high diagnostic value in evaluating the severity level of pulmonary arterial hypertension in patients with congenital heart disease. The diagnostic performance of MPI at pre-treatment patients was superior to that at post-treatment. More cases need to be included for further study. PMID- 29177255 TI - Cell and gene therapy with reporter gene imaging in myocardial ischemia. AB - OBJECTIVE: Reporter gene/probe systems have proved to be reliable for monitoring gene/cell therapy. We sought to evaluate whether a reporter gene/probe system, namely the human estrogen receptor ligand binding domain (hERL)/16alpha-18F fluoro-17beta-estradiol (18F-FES), could be used for monitoring vascular endothelial growth factor (VEGF) gene expression and response to bone marrow mesenchymal stem cell (MSCs) therapy in ischemic heart disease. ANIMALS AND METHODS: Reporter gene hERL and therapeutic gene VEGF165 were linked through internal ribosome entry site (IRES), and then the recombinant adenovirus vector Adenovirus 5-hERL-IRES-VEGF (Ad5-EIV) was constructed and transfected into MSCs, and named Ad5-EIV-MSCs. Rat myocardial infarction was induced by coronary arterial branch ligature, and Ad5-EIV-MSCs were transplanted by injection into the peripheral myocardium, while non-transfected MSCs transplantation used as controls. Fluorine-18-FDG micro-PET imaging was performed to confirm myocardial infarction 1 day after surgery. Fluorine-18-FES micro-PET/CT images were acquired 2 days after Ad5-EIV-MSCs transplantation. Myocardial specimens were obtained and stained with hematoxylin-eosin (H&E) staining to verify the myocardial infarction. The expression of estrogen receptor (ER) and VEGF was detected using immunohistochemistry (IHC). RESULTS: Rat myocardial infarction models were successfully produced and confirmed by H&E staining. Images of 18F-FDG PET showed obvious reduced or absent uptake of 18F-FDG on the infarct myocardium, while uniform and well-distribution on the normal myocardium. 18F-FES micro-PET/CT showed the tracer notable accumulated in the apical region where Ad5-EIV-MSCs were injected with an uptake value of 0.38+/-0.09%ID/g, which was much higher than that of surrounding normal myocardium with nearly no uptake of 18F-FES (0.10+/-0.03%ID/g, n=5, P<0.05). In the group of non-transfected MSCs, the apical uptake was similar to that of normal myocardium. Immunohistochemistry studies demonstrated positive expression of both ER and VEGF in the involved region accompanied by active angiogenesis. CONCLUSION: This study confirmed that hERL/18F-FES could be used as a reporter gene/probe system for monitoring gene and cell therapy in the ischemic heart disease. PMID- 29177256 TI - Errors in the absorbed and the administered 131I therapeutic dose in patients with Graves' disease. A suggested more precise technique. AB - OBJECTIVE: The aim of this study was to evaluate the relative error (RE) in the thyroid absorbed dose (TD) of iodine-131 (131I) in patients with Graves' disease comparing the simplified Quimby-Marinelli-Hine formula method (sQMHF) and the Standard Operational Procedures for dosimetry (SOPD) recommended by the European Association of Nuclear Medicine. PATIENTS AND METHODS: This study included 45 patients with Graves' disease 12 men and 33 women; age 44.1+/-12.8 years. Thyroid mass (TM) was measured using ultrasound. Uptake of 131I (RAIU) was tested at 2, 4 6, 24, 48-72, and 96-168h after its administration and the half-life (T1/2eff) and resident time (RT) of 131I were computed. According to the sQMHF, a prescribed TD of 75Gy required 3.7MBq/g of 131I, correction based on the RAIU24h and T1/2eff. Subsequently, the therapeutic TD was computed according to the SOPD and the RE was recorded. The data were analyzed using t-tests. RESULTS: The TM, RAIU24h, therapeutic TD, and RE were 36.5+/-23.9g, 0.54+/-0.14, 89.4+/-9.4Gy, and -0.01+/-0.02, respectively. There was a significant difference (t-value 9.84, P<0.01) between the prescribed and therapeutic TD because the sQMHF ignores the absorbed dose deposited in the thyroid during the first 24h, which is included in the SOPD. In addition, the RE was significantly smaller than the variable coefficient (VC) of the therapeutic TD (t=-39.6, P<0.01). CONCLUSION: When the activity of 131I was calculated using the simplified Q-M-H formula, the therapeutic absorbed thyroid dose was significantly higher than what was expected for the prescribed dose. Precision of the individualized therapeutic absorbed dose could be improved by computing the activity of 131I using the standard operational procedures for dosimetry of the EANM. PMID- 29177257 TI - Assessment of segmental left ventricular thickening in diabetic type II obese patients with normal myocardial perfusion scan. AB - OBJECTIVE: The aim of this study is to investigate whether gated single photo emission tomography (gSPET) can be used to detect subclinical left ventricular systolic dysfunction (LVSD) in obese diabetic type II patients. SUBJECTS AND METHODS: We retrospectively reviewed gSPET images of 190 patients with diabetes mellitus type II (DM II) (137 females and 53 males) with normal myocardial perfusion and normal ejection fraction (EF). Standardized twenty segment polar maps of thickening and motion were generated. Correlation between body mass index (BMI) and thickening for each segment was performed. RESULTS: Statistically significant results were reported in female patients including: negative correlation between BMI and EF (-0.19, P=0.03). End diastolic volume (EDV) also significantly increased with increasing BMI (0.25, P<0.01). There was also statistically significant negative correlation between septal thickening and BMI segment 15 (-0.19, P=0.02), segment 16 (-0.22, P=0.01), segment 18 (-0.20, P=0.01), segment 19 (-0.25, P=0.003), segment 20 (-0.2, P=0.02)]. No statistical significant correlation was found between thickening and BMI in male patients. CONCLUSION: This is the first time where thickening as measured by gSPET has been used to demonstrate subclinical LVSD in DM II obese patients. The relationship between gender and obesity on cardiovascular function and structure needs further investigations. PMID- 29177258 TI - Is 18F-FDG PET/CT a valuable diagnostic tool for verifying accelerated atherosclerosis secondary to diabetes mellitus on insulin in the aortic segments and large arteries? AB - OBJECTIVE: Fluorine-18 fluorodeoxylglucose positron emission tomography/computed tomography (18F-FDG PET/CT) has a well-established role for detection and quantification of atherosclerotic inflammatory disease using standardized uptake value (SUV) measurements. Our aim was to compare the inflammatory and macroscopic calcification processes of atherosclerosis in the aortic segments and large arteries of subjects with insulin dependent diametes mellitus (IDDM) compared to those of age-matched controls via 18F-FDG PET/CT. PATIENTS AND METHODS: A hundred and ten subjects who underwent 18F-FDG PET/CT imaging for oncological diseases were retrospectively studied. Fifty five were diabetics on insulin and 55 were age-matched controls. Average SUVmax and SUVmean for four segments of aorta and for common iliac arteries and femoral arteries were measured and compared between subject groups. Presence or absence of macroscopic calcification on CT images for each arterial segment was also noted and compared between these groups. RESULTS: Average SUVmax and SUVmean were statistically significantly greater in subjects with IDDM compared to controls in all arterial segments (P<=0.001). Presence of calcification on CT was more frequently encountered in 6 of the 8 segments in subjects with IDDM, and there was statistically significantly difference for the descending aorta and abdominal aorta. CONCLUSION: Our results show that inflammatory component of atherosclerosis was more severe in all aortic segments in subjects with IDDM compared to those of controls. Presence of macroscopic calcification also detected to be more frequently encountered in the descending thoracic and abdominal aorta in subjects with IDDM. Fluorine-18-FDG PET/CT is a valuable diagnostic tool for detecting and semi-quantifying accelerated atherosclerotic inflammatory and calcific changes secondary to diabetes mellitus treated with insulin in the aortic segments and large arteries. PMID- 29177259 TI - The influence of adipose tissue volume can significantly affect the metabolic activity of reference organs in 18F-FDG PET/CT studies of a normal healthy population. AB - OBJECTIVE: This study investigated whether fluorine-18-fluorodeoxyglucose (18F FDG) uptake of reference organs can be affected by subjects' factors in positron emission tomography/computed tomography (PET/CT) in a healthy population. SUBJECTS AND METHODS: A total of 208 normal healthy subjects without diabetes or dyslipidemia were included. Adipose tissue volume was measured by CT images from a dedicated PET/CT scan. Uptake of 18F-FDG of reference organs was measured from liver, blood pool, and muscle, and was normalized by lean body anthropometric data and adipose tissue volume. RESULTS: Of 208 participants, 118 were metabolically healthy lean (MHL); with body mass index (BMI) <25kg/m2 and 90 were metabolically healthy obese (MHO) with; BMI>=25kg/m2 . These subjects had significantly higher values of liver, blood pool, and muscle than did the MHL subjects (P<0.001 for both). Among subjects' factors, adipose tissue volume revealed strongest correlation with standardized uptake value multiplied by lean body weight divided by body weight (SUL) of liver (r=0.754, P<0.001), of blood pool (r=0.756, P<0.001) and of muscle (r=0.635, P<0.001). On regression analysis, adipose tissue volume was determined to be a common independent predictor for SUL of liver, blood pool and muscle (P<0.001) and furthermore was serum C-reactive protein level for SUL of the liver and also age and serum insulin level for SUL of blood pool. CONCLUSION: Adipose tissue volume can significantly affect SUL of liver, blood pool, and muscle in a healthy population. Liver and blood pool may have limited roles as reference organs for normalization of 18F-FDG uptake of the lesion.

PMID- 29177261 TI - Performance and safety profile of regadenoson myocardial perfusion imaging: first experience in Greece. AB - OBJECTIVE: MPI can provide valuable information in the investigation of patients with known or suspected coronary artery disease. The stress component of the studies can be conducted with regadenoson, which was approved for clinical use in Greece in 2016. We investigated the performance and safety profile of regadenoson MPI based on our 7 months institutional experience. PATIENTS AND METHODS: We studied 96 consecutive patients (59 males, 37 females, mean age 70.35y.o, range: 46-87y.o.) referred to our department for a clinically indicated MPI study with pharmacological stress. Eleven patients suffered from chronic obstructive pulmonary disease. Patients underwent regadenoson stress test, combined with both stress and rest imaging. Data on the symptoms and electrocardiographic changes due to regadenoson administration were recorded. Symptoms were graded as 1-mild: a symptom that did not distress the patient, 2-moderate: a symptom that distressed the patient but it was self-limiting, or 3-severe: a symptom that distressed the patient requiring medical intervention. RESULTS: Regadenoson related symptoms were reported in 56 patients and were: dyspnea, discomfort, dizziness, chest pain, epigastric pain, neck pain, headache, flushing, nausea, heartburn, weakness, and upper limbs numbness. The severity of symptoms was recorded as grade 1 in 30 patients, grade 2 in 25 patients, and grade 3 in 1 patient. Two or more different symptoms were reported in 28 patients. Ischemic electrocardiographic changes and arrhythmias were observed in 8 patients. CONCLUSION: Our findings support previously published data indicating the optimal safety profile of regadenoson MPI, even in the group of patients suffering from chronic obstructive pulmonary disease.

AB - OBJECTIVE: The aim of this study was to compare the metabolic activity of metastatic foci from breast and prostate cancer patients as scanned by fluorine 18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) and by technetium-99m methyl diphosphonate (99mTc-MDP) bone scan (BS). SUBJECTS AND METHODS: Forty one patients were studied, divided into 2 groups based on histologically confirmed diagnosis: a) Breast cancer group, 23 women, mean age: 61+/-12 years, range: 37-79 years and, b) Prostate cancer group, 18 men, mean age 68+/-8 years, range: 52-82 years. Another group of 17 non cancer atherosclerotic subjects 9 women and 8 men, of mean age and age range similar to the above were also studied for comparison. The R index (the total count rate in bone metastases divided by the total count rate in a contralateral area), the maximum semi-quantitative standardized uptake value (SUVmax) of BS lesions and the mean number of metastases were evaluated. For the metastatic findings in the PET/CT scans the automatic method of contouring with 50% background cut-off was used, while for the 99mTc-MDP BS metastases were delineated manually. RESULTS: The mean R index of the bone metastatic foci studied by 18F-FDG PET/CT was 1.89+/ 0.69 for Groups I and II patients. There was no significant difference of the R index between prostate cancer and breast cancer metastases (1.95+/-0.86 vs 1.83+/ 0.52). The average SUVmax value was significantly higher in breast cancer patients than in prostate cancer patients (5.15+/-2.54 vs 4.01+/-1.71; P<0.05). There was no significant correlation in both cancer groups between R index and SUVmax values. The number of metastatic foci diagnosed by the 99mTc-MDP BS scan was much less than by the 18F-FDG PET/CT. CONCLUSION: No significant correlation was noticed in the metabolic activity-glucose utilization of metastatic bone foci between breast and prostate cancer cases. This observation validates the independent value of analyzed diagnostic methods and suggests negligible influence of glucose utilization in bone re-modeling in the above metastatic cancer cells. The 18F-FDG PET/CT bone scan was much better in diagnosing metastases compared to the 99mTc-MDP scan. PMID- 29177263 TI - Primary radiation dosimetry of a novel PET radiopharmaceutical 68Ga-NODAGA glycine in comparison with 99mTc-DTPA in renal studies. AB - OBJECTIVE: In this study, we tried to estimate human absorbed dose of 68Ga-NODAGA glycine as a new potential positron emission tomography (PET) renal agent based on the biodistribution data reported in healthy rats, and compare our estimation with the available absorbed dose data from technetium-99m diethylenetriaminepentaacetic acid (99mTc-DTPA). SUBJECTS AND METHODS: The medical internal radiation dose (MIRD) formulation was applied to extrapolate from rats to human and to project the absorbed radiation dose for various organs in humans. S factor calculated by Monte-Carlo N-particle (MCNP) simulation and also this factor has been taken from the tables presented in MIRD pamphlet No.11. Hence, two radiation absorbed dose were calculated for organs. RESULTS: Our dose prediction shows that an 185MBq injection of gallium-68-1,4,7-triazacyclononane-1 gamma-glutamylglycine-4,7-diacetic acid (68Ga-NODAGA-glycine) in humans might result in an estimated absorbed dose of 0.063mGy in the whole body when S factor calculated by MCNP simulation. The highest absorbed doses are observed in kidneys, lungs, spleen, liver, and red marrow with 3.510, 0.453, 0.335, 0.268, and 0.239mGy, respectively. In addition to, the estimated absorbed dose for total body after injection of 185MBq of 68Ga-NODAGA-glycine is 0.053mGy when S factor has been taken from MIRD pamphlet No.11. The highest absorbed doses are observed in kidneys, lungs, liver, spleen, and red marrow with 3.110, 0.438, 0.209, 0.203, and 0.203mGy, respectively. Comparison between human absorbed dose estimation for 68Ga-NODAGA-glycine and 99mTc-DTPA indicated that the absorbed dose of the most organs after injection of 99mTc-DTPA is higher than the amount after 68Ga-NODAGA glycine. CONCLUSION: The results showed that 68Ga-NODAGA-glycine delivers lower dose to the patients. Also due to its application in PET (which offers higher sensitivity and spatial resolution compared to planar or SPET), 68Ga-NODAGA glycine would be a superior choice than 99mTc-DTPA for renography and impose less radiation doses to patients.

Seven months follow-up. AB - We studied a 50 years old male patient who underwent cardiac resynchronization therapy on and off (CRT-on and CRT-off) for assessment of left ventricular (LV) function and mechanical systole synchrony using gated myocardial perfusion imaging (gMPI) and real-time three-dimensional echocardiography (RT3DE). The patient was reexamined after seven months. The comparison of these two modalities showed consistent results on assessing both the CRT-on and CRT-off conditions. This result may indicate that an immediate synchronization parameter change during CRT-on may be valuable for predicting response to CRT surgery. PMID- 29177265 TI - Metastatic melanoma response to combination therapy with ipilimumab and vemurafenib. AB - Combination therapies for the treatment of metastatic melanoma are a matter of debate nowadays. We report on a stage IV metastatic melanoma patient with the BRAF V600 mutation and a large tumor burden initially treated with two cycles of ipilimumab. Due to dramatic disease progression, demonstrated on interim 18F-FDG PET/CT, vemurafenib was added in the patient's therapeutical scheme. After completion of the concurrent ipilimumab and vemurafenib administration, a third 18F-FDG PET/CT showed an impressive metabolic remission of the metastatic disease, reflecting the potential role of the modality in treatment response evaluation of melanoma patients receiving combination therapies. PMID- 29177266 TI - Atypical Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis simulating lymphadenitis on 18F-FDG PET/CT and its differential diagnosis. AB - Diagnosis of Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH) is challenging as its clinical presentation is atypical. Here we present a case of atypical EBV-HLH simulating lymphadenitis on fluorrine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT), with a view to consider this kind of EBV-HLH as a possible differential diagnosis in lymphadenitis. A 68 years old male who had episodic fever accompanied by weight loss and weakness for two weeks was studied. Finally, biopsies in bone marrow and spleen revealed hemophagocytic cells. He was diagnosed with EBV-HLH and treated with etoposide and prednisone. His condition started improving soon, and his abnormal laboratory findings were normalized at day 15. He remained in good clinical condition at 3 months follow-up after hospital discharge. PMID- 29177267 TI - Primary and secondary hyperparathyroidism among vitamin D deficient Hashimoto's thyroiditis patients and the need for a parathyroid scan. AB - The patients with Hashimoto thyroiditis must be investigated mainly for secondary hyperparathyroidism due to vitamin D deficiency/insufficiency. Parathyroid scintigraphy has no place in the diagnosis of primary, secondary or tertiary hyperparathyroidism or in the decision for surgical treatment. Parathyroid scintigraphy is a useful preoperative technique for the localization of the pathological parathyroid glands. PMID- 29177268 TI - Advanced manufacturing of microdisk vaccines for uniform control of material properties and immune cell function. AB - The continued challenges facing vaccines in infectious disease and cancer highlight a need for better control over the features of vaccines and the responses they generate. Biomaterials offer unique advantages to achieve this goal through features such as controlled release and co-delivery of antigens and adjuvants. However, many synthesis strategies lead to particles with heterogeneity in diameter, shape, loading level, or other properties. In contrast, advanced manufacturing techniques allow precision control of material properties at the micro- and nano-scale. These capabilities in vaccines and immunotherapies could allow more rational design to speed efficient design and clinical translation. Here we employed soft lithography to generate polymer microdisk vaccines with uniform structures and tunable compositions of vaccine antigens and toll like receptor agonists (TLRas) that serve as molecular adjuvants. Compared to conventional PLGA particles formed by emulsion, microdisks provided a dramatic improvement in the consistency of properties such as diameter. During culture with primary dendritic cells (DCs) from mice, microdisks were internalized by the cells without toxicity, while promoting co-delivery of antigen and TLRa to the same cell. Analysis of DC surface activation markers by flow cytometry revealed microdisk vaccines activated dendritic cells in a manner that depended on the level of TLRa, while antigen processing and presentation depended on the amount of antigen in the microdisks. Together, this work demonstrates the use of advanced manufacturing techniques to produce uniform vaccines that direct DC function depending on the composition in the disks.

AB - A novel multifunctional logic gate based on a triple-chromophore (coumarin-NBD flavylium, CNF) fluorescent biothiol probe with diverse fluorescence signal patterns was rationally designed and synthetized. On the new triad CNF, diverse logic operations such as OR, TRANSFER, INH, NOT, and YES logic gates were achieved by using biothiols and fluorescence signal patterns as the multiple inputs and outputs, respectively. PMID- 29177270 TI - Assembly of protonated mesoporous carbon nitrides with co-catalytic [Mo3S13]2- clusters for photocatalytic hydrogen production. AB - The photocatalytic activity of protonated ordered mesoporous carbon nitride (pom CN) was significantly improved by assembling anionic [Mo3S13]2- clusters as cocatalysts onto the surface and channel of pom-CN via electrostatic interactions. This work demonstrates the feasibility of employing solution chemistry to assemble co-catalysts in the form of ionic clusters as building blocks into a photosynthetic architecture. PMID- 29177271 TI - f-Block complexes of a m-terphenyl dithiocarboxylate ligand. AB - Straightforward syntheses are provided for the m-terphenyl dithiocarboxylic acid 2,6-(C6H4-4-tBu)2C6H3CS2H (TerphCS2H, 2) and its lithium and potassium salts, TerphCS2Li(Et2O)2 and TerphCS2K (1.Et2O and 4, respectively). These compounds can be isolated in good yields on multi-gram scales starting from Terph-I without isolating intermediates. Salt metathesis and protonolysis reactions provided access to the homoleptic actinide(iv) complexes (TerphCS2)4An (An = Th (5) and U (6)). Electrochemical and reactivity studies revealed that the dithiocarboxylate ligand is incompatible with U(iii). The homoleptic lanthanum(iii) complex (TerphCS2)3La and its eta6-toluene adduct (7 and 7.tol, respectively) were also structurally characterized. Binding of toluene to 7 was shown to displace intramolecular La-Carene close contacts that are facilitated by a distortion from the usual geometry of bound dithiocarboxylate ligands. PMID- 29177272 TI - Luminescent cadmium(ii) coordination polymers of 1,2,4,5-tetrakis(4 pyridylvinyl)benzene used as efficient multi-responsive sensors for toxic metal ions in water. AB - Reactions of Cd(NO3)2.4H2O with 1,2,4,5-tetrakis(4-pyridylvinyl)benzene (4-tkpvb) and 5-tert-butylisophthalic acid (5-tert-H2BIPA), 1,3,5-benzenetricarboxylic acid (1,3,5-H3BTC) or 1,4-naphthalenedicarboxylic acid (1,4-H2NDC) under solvothermal conditions afforded three two-dimensional (2D) Cd(ii) coordination polymers [Cd(4 tkpvb)(5-tert-BIPA)]n (1), [{Cd(4-tkpvb)(1,3,5-HBTC)}.0.5DMF]n (2) and [Cd(4 tkpvb)(1,4-NDC)]n (3). Compounds 1-3 were structurally characterized by IR, elemental analysis, powder X-ray diffraction, and single crystal X-ray diffraction. Compounds 1-3 possess unique 2D networks in which 1D double chains [Cd2L2]n (L = 5-tert-BIPA or 1,3,5-HBTC) (1-2) or 1D linear chains [Cd(1,4-NDC)]n (3) are linked by 4-tkpvb ligands. Upon UV light excitation, a 4-tkpvb solution in DMF showed an emission band centered at 446 nm with a shoulder at 475 nm. The addition of Hg2+ ions into the 4-tkpvb solution in DMF remarkably changed its colour from colourless to yellow under natural light, or from blue to grey yellow under UV light, which were clearly visible to the naked eye. Compounds 1-3 suspended in water could emit yellow-green light under UV light irradiation. The representative compound 1 was confirmed to be an uncommon multi-responsive luminescent sensor for Hg2+, CrO42- and Cr2O72- ions in water by the luminescence quenching method. The detection limits for these species were 0.15 MUM (Hg2+), 0.08 MUM (CrO42-) and 0.12 MUM (Cr2O72-), respectively. The luminescence quenching mechanism studies revealed that these quenching processes were involved in either the interaction of Hg2+ with free pyridyl groups in 1 or the overlap between the absorption band of CrO42- or Cr2O72- and the excitation and/or emission bands of 1.

AB - A metal-free gem-functionalization reaction of diazo compounds with N sulfenylsuccinimides via a formal N-S bond insertion process has been reported. The transformation features mild reaction conditions, broad substrate scope and functional group tolerance, offering an efficient approach to sulfide synthesis in moderate to high yields. In addition, the mechanism studies indicate the formation of free carbene under thermal conditions followed by ylide generation, then N-S bond cleavage and C-N bond formation occurred in sequence to give the sulfide products. PMID- 29177274 TI - Synthesis of 4-substituted pyrazole-3,5-diamines via Suzuki-Miyaura coupling and iron-catalyzed reduction. AB - A general and efficient synthesis of 4-substituted-1H-pyrazole-3,5-diamines was developed to access derivatives with an aryl, heteroaryl, or styryl group, which are otherwise relatively difficult to prepare. The first step is based on the Suzuki-Miyaura cross-coupling reaction utilizing the XPhos Pd G2 precatalyst. The coupling reactions of 4-bromo-3,5-dinitro-1H-pyrazole with the electron rich/deficient or sterically demanding boronic acids enabled the production of the corresponding dinitropyrazoles. The subsequent iron-catalyzed reduction of both nitro groups with hydrazine hydrate accomplished the synthesis. The additional demethylation of the 4-methoxystyryl derivative allowed the production of the carboanalog of CAN508 reported as a selective CDK9 inhibitor. PMID- 29177275 TI - Fundamental properties and practical applications of ionic liquids: concluding remarks. AB - The Faraday Discussion on Ionic Liquids: From Fundamental Properties to Practical Applications took place in Cambridge in September 2017. Fundamental understanding of behaviour of liquids in the bulk and at surfaces was the primary emphasis of most of the talks, although applications were the motivation for the selection of many of the research projects. However, the conference almost entirely omitted discussion of the potential role of ionic liquids in green chemistry. Although initial claims of ionic liquids (ILs) being green were overstated, the search for green ionic liquids is still very much a worthwhile endeavour. Some confusion in the field has been caused by an overemphasis on the environmental impacts of ILs themselves, despite the fact that the manufacture of ILs causes greater impacts. Additional confusion has arisen from the mistaken use of the ready biodegradability test as an indicator for ultimate degradation. Because some ILs contain cores that are highly resistant to degradation, the ready biodegradability test can give a false positive result. The author offers suggestions as to how to tackle the problem of searching for greener ILs, including a greater focus on the impacts of the synthetic pathways of relevant ions. The final decision of whether an IL is green can only come from an application-specific life cycle assessment of a product or process using the IL compared to the same product/process using competing liquids. PMID- 29177277 TI - Path-integral simulation of graphene monolayers under tensile stress. AB - Finite-temperature properties of graphene monolayers under tensile stress have been studied by path-integral molecular dynamics (PIMD) simulations. This method allows one to consider the quantization of vibrational modes in these crystalline membranes and to analyze the influence of anharmonic effects on the membrane properties. Quantum nuclear effects turn out to be appreciable on the structural and thermodynamic properties of graphene at low temperature, and they can even be noticeable at room temperature. Such quantum effects become more relevant as the applied stress is increased, mainly for properties related to out-of-plane atomic vibrations. The relevance of quantum dynamics in the out-of-plane motion depends on the system size, and is enhanced by tensile stress. For applied tensile stresses, we analyze the contribution of the elastic energy to the internal energy of graphene. Results of PIMD simulations are compared with calculations based on a harmonic approximation for the vibrational modes of the graphene lattice. This approximation describes rather well the structural properties of graphene, provided that the frequencies of ZA (flexural) acoustic modes in the transverse direction include a pressure-dependent correction.

AB - We report the automated glycan assembly of oligosaccharides related to the plant cell wall hemicellulosic polysaccharide xyloglucan. The synthesis of galactosylated xyloglucan oligosaccharides was enabled by introducing p methoxybenzyl (PMB) as a temporary protecting group for automated glycan assembly. The generated oligosaccharides were printed as microarrays, and the binding of a collection of xyloglucan-directed monoclonal antibodies (mAbs) to the oligosaccharides was assessed. We also demonstrated that the printed glycans can be further enzymatically modified while appended to the microarray surface by Arabidopsis thaliana xyloglucan xylosyltransferase 2 (AtXXT2).

AB - A series of Ln-doped KSrPO4 (Ln = Ce3+, Eu3+, Eu2+, Pr3+) phosphors are prepared through a high-temperature solid-state method. The KSrPO4 compound is confirmed to possess a beta-K2SO4 structure with the Pnma group by Rietveld refinement, and the temperature-dependent lattice parameters are investigated with the powder X ray diffraction results at different temperatures. Ce3+ and Eu3+ ions are introduced to probe the crystal field strength (CFS) and the lanthanide site symmetry by using VUV-UV-vis spectroscopy. The temperature-dependent luminescence properties of KSrPO4: Ce3+/Eu2+ exhibit an excellent thermal stability of Ce3+/Eu2+ luminescence. Based on the VUV-UV-vis spectra of Ce3+ and Eu3+ doped KSrPO4, the vacuum referred binding energy (VRBE) scheme is constructed to understand the redox properties of Eu, the 5d energy levels of Pr3+ and the thermal quenching characteristics of Ce3+ and Eu2+ luminescence. PMID- 29177279 TI - Study of Ce-Cu mixed oxide catalysts by in situ electrical conductivity measurements. AB - Three Ce-Cu mixed oxides, namely Ce0.95Cu0.05, Ce0.6Cu0.4 and Ce0.15Cu0.85, along with pure CeO2 and CuO were characterized by in situ electrical conductivity measurements. Their electrical conductivity was studied as a function of temperature and oxygen partial pressure, and was followed with time during successive exposure to air, nitrogen and different gaseous mixtures containing propane as a VOC model molecule, under conditions close to those of their catalytic applications. CeO2 and CuO appeared to be n-type and p-type semiconductors, respectively, while the semiconducting behavior of the Ce-Cu mixed oxides depended on the oxide composition. The semiconductive and redox properties of the samples were correlated with their catalytic behavior in CO oxidation, ethene total oxidation and soot combustion. PMID- 29177280 TI - A computational investigation of the solvent-dependent enantioselective intramolecular Morita-Baylis-Hillman reaction of enones. AB - The intramolecular Morita-Baylis-Hillman reaction of beta-mono and beta,beta disubstituted enones shows high yields and stereo-selective products when the reaction is performed in the presence of 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) as a solvent. In this work, we carried out a computational study using the density functional Becke 3-(B3) parameter exchange and the Lee-Yang-Parr (LYP) correlation functional and 6-31+G* basis set. Two major steps i.e. C-C bond formation and proton transfer were analysed using different pathways. The calculations show a very low barrier (DeltaG? = 0.23 kcal mol-1) for C-C bond formation in the case of an experimentally dominant product. For this pathway the subsequent proton transfer via the HFIP step has a barrier of 26.98 kcal mol-1. The same has been confirmed using a Molecular Electrostatic Potential (MESP), which shows a negative region in between CC in the transition state. In spite of high barriers for proton transfer, the intermediate products formed in this reaction pathway are thermodynamically more stable in comparison with other pathways. The thermodynamic stability of the final product in this pathway is observed to surpass all other effects in the presence of HFIP, thereby corroborating the experimentally observed enantioselectivity. PMID- 29177281 TI - The development of ruthenium(ii) polypyridyl complexes and conjugates for in vitro cellular and in vivo applications. AB - Ruthenium(ii) [Ru(ii)] polypyridyl complexes have been the focus of intense investigations since work began exploring their supramolecular interactions with DNA. In recent years, there have been considerable efforts to translate this solution-based research into a biological environment with the intention of developing new classes of probes, luminescent imaging agents, therapeutics and theranostics. In only 10 years the field has expanded with diverse applications for these complexes as imaging agents and promising candidates for therapeutics. In light of these efforts this review exclusively focuses on the developments of these complexes in biological systems, both in cells and in vivo, and hopes to communicate to readers the diversity of applications within which these complexes have found use, as well as new insights gained along the way and challenges that researchers in this field still face. PMID- 29177282 TI - Dense monolayer films of atomically precise graphene nanoribbons on metallic substrates enabled by direct contact transfer of molecular precursors. AB - Atomically precise graphene nanoribbons (GNRs) of two types, chevron GNRs and N = 7 straight armchair GNRs (7-AGNRs), have been synthesized through a direct contact transfer (DCT) of molecular precursors on Au(111) and gradual annealing. This method provides an alternative to the conventional approach for the deposition of molecules on surfaces by sublimation and simplifies preparation of dense monolayer films of GNRs. The DCT method allows deposition of molecules on a surface in their original state and then studying their gradual transformation to polymers to GNRs by scanning tunneling microscopy (STM) upon annealing. We performed STM characterization of the precursors of chevron GNRs and 7-AGNRs, and demonstrate that the assemblies of the intermediates of the GNR synthesis are stabilized by pi-pi interactions. This conclusion was supported by the density functional theory calculations. The resulting monolayer films of GNRs have sufficient coverage and density of nanoribbons for ex situ characterization by spectroscopic methods, such as Raman spectroscopy, and may prove useful for the future GNR device studies. PMID- 29177284 TI - Fluorescence light-up detection of cyanide in water based on cyclization reaction followed by ESIPT and AIEE. AB - Schiff base 1 (2,4-di-tert-butyl-6-((2-hydroxyphenyl-imino)-methyl)phenol) containing two hydroxyl groups could undergo an oxidative cyclization reaction and then generate hydroxyphenylbenzoxazole (HBO) 2 when CN- was present as a catalyst. The multistep cyclization reaction was proved by spectroscopy, 1H NMR, 13C NMR and mass spectra. C[double bond, length as m-dash]N isomerization is the predominant decay process of the excited states, so sensor 1 is weakly emissive in solution at ambient temperature. When 1 reacts with CN-, the emission is remarkably enhanced, where 1 is converted to 2. The cyclization product HBO 2 displays bright green luminescence in micellar due to the ESIPT (excited-state intramolecular proton transfer) as well as AIEE (aggregation-induced emission enhancement) effect. The detection limit is 5.92 * 10-7 M, lower than the WHO guideline of CN- in drinking water (1.9 MUM). The selective and competitive experiments reveal that sensor 1 shows high sensing selectivity and sensitivity for CN- over other anions. Test papers containing absorbed 1 were prepared and applied for practical application of cyanide detection. PMID- 29177283 TI - A new class of dual responsive self-healable hydrogels based on a core crosslinked ionic block copolymer micelle prepared via RAFT polymerization and Diels-Alder "click" chemistry. AB - Amphiphilic diblock copolymers of poly(furfuryl methacrylate) (PFMA) with cationic poly(2-(methacryloyloxy)ethyltrimethyl ammonium chloride) (PFMA-b-PMTAC) and anionic poly(sodium 4-vinylbenzenesulfonate) (PFMA-b-PSS) were prepared via reversible addition fragmentation chain-transfer (RAFT) polymerization by using PFMA as a macro-RAFT agent. The formation of the block copolymer was confirmed by FTIR and 1H NMR analyses. In water, the amphiphilic diblock copolymers, (PFMA-b PMTAC) and (PFMA-b-PSS), formed micelles with PFMA in the core and the rest of the hydrophilic polymers like PMTAC and PSS in the corona. The PFMA core was crosslinked by using Diels-Alder (DA) "Click" chemistry in water at 60 degrees C where bismaleimide acted as a crosslinker. Afterwards, both the core crosslinked micelles were mixed at an almost equal charge ratio which was determined by zeta potential analysis to prepare the self-assembled hydrogel. The de-crosslinking of the hydrophobic PFMA core in the self-assembled hydrogel via rDA reaction took place at 165 degrees C as determined from DSC analysis. This hydrogel showed self-healing behavior using ionic interaction (in the presence of water) and DA chemistry (in the presence of heat). PMID- 29177285 TI - Investigations on structural determination of semi-transition-metal borides. AB - Lack of systematic investigations on their dynamical and energetic stability preclude the full understanding of the structural determination and the corresponding mechanical properties for the semi-transition-metal borides epsilon2B (epsilon = Ti, V, Cr, Mn, Fe, Co, Ni, Nb, Mo, Ta, and W). The present energetic calculations show nu2B (nu = Ti, V, Cr, Nb, Mo, Ta and W) with the long assumed I4/mcm symmetry are dynamically unstable, stemming from the large volume required to accommodate the boron atom at equilibrium. By freezing the unstable phonon mode, I4/m structure is predicted to be both energetically and dynamically stable. The structural stabilities for these compounds at finite temperature have been identified by the calculated Gibbs free energies and ab initio molecular dynamic simulation.

AB - We present a theoretical description of double-pump femtosecond single-molecule signals with fluorescence detection. We simulate these signals in the weak-field regime for a model mimicking a chromophore with a Franck-Condon-active vibrational mode. We establish several signatures of these signals which are characteristic for the weak-field regime. The signatures include the quenching of vibrational beatings by electronic dephasing and a pronounced tilt of the phase time profiles in the two-dimensional (2D) maps. We study how environment-induced slow modulations of the electronic dephasing and relevant chromophore parameters (electronic energy, orientation, vibrational frequency and relative shift of the potential energy surfaces) affect the signals. PMID- 29177287 TI - All-gas-phase synthesis of amino-functionalized UiO-66 thin films. AB - Thin films of metal-organic frameworks (MOFs) prepared using all-gas-phase techniques such as atomic/molecular layer deposition (ALD/MLD) are emerging due to their potential for enabling suitable applications. Their high and specific porosity enables their use as membranes for separations and as a basis for sensors in microelectronics, provided that films can be made. The properties of such MOF materials can be tuned by choosing linker molecules that are functionalized with a variety of chemical groups. However, thin films of these functionalised MOFs have so far been prepared through wet based chemistries, which are difficult to combine with microelectronics and high aspect ratio structures. We here report on the thin film deposition of amino-functionalised UiO-66 through an all-gas-phase ALD/MLD process. By using amino-functionalised linkers, modulation by acetic acid to control the stoichiometry of the deposited film was no longer required, as opposed to the case in which unmodified terephthalic acid was used as a linker. The growth and properties of the films were characterised using an in situ quartz crystal microbalance (QCM), spectroscopic ellipsometry (SE), grazing incidence X-ray diffraction (GIXRD), Fourier transform infrared spectroscopy (FTIR) and other techniques to obtain information on their growth dynamics and physical properties. PMID- 29177288 TI - Rational one-step synthesis of porous PtPdRu nanodendrites for ethanol oxidation reaction with a superior tolerance for CO-poisoning. AB - Precise fabrication of porous ternary Pt-based nanodendrites is very important for electrochemical energy conversion owing to high surface area and great molecular accessibility of these nanodendrites. Herein, PtPdRu porous nanodendrites (PNDs) were prepared via a facile one-step ultrasonic irradiation approach at room temperature. Intriguingly, the ultrasonic irradiation drove the formation of PtPdRu PNDs with spatially interconnected porous structures, whereas magnetic stirring produced PtPdRu nanoflowers (NFs) with less porosity. The formation mechanism was ascribed to the acoustic cavitation effect and fast reduction kinetics under sonication. The as-made PtPdRu PNDs displayed a superior catalytic performance towards ethanol oxidation reaction with a high tolerance for CO-poisoning as compared to PtPdRu NFs, PtPd NDs, and commercial Pt/C catalyst. PMID- 29177289 TI - Double anisotropic electrically conductive flexible Janus-typed membranes. AB - Novel type III anisotropic conductive films (ACFs), namely flexible Janus-typed membranes, were proposed, designed and fabricated for the first time. Flexible Janus-typed membranes composed of ordered Janus nanobelts were constructed by electrospinning, which simultaneously possess fluorescence and double electrically conductive anisotropy. For the fabrication of the Janus-typed membrane, Janus nanobelts comprising a conductive side and an insulative fluorescent side were primarily fabricated, and then the Janus nanobelts are arranged into parallel arrays using an aluminum rotary drum as the collector to obtain a single anisotropically conductive film. Subsequently, a secondary electrospinning process was applied to the as-prepared single anisotropically conductive films to acquire the final Janus-typed membrane. For this Janus-typed membrane, namely its left-to-right structure, anisotropic electrical conduction synchronously exists on both sides, and furthermore, the two electrically conductive directions are perpendicular. By modulating the amount of Eu(BA)3phen complex and conducting polyaniline (PANI), the characteristics and intensity of the fluorescence-electricity dual-function in the membrane can be tuned. The high integration of this peculiar Janus-typed membrane with simultaneous double electrically conductive anisotropy-fluorescent dual-functionality is successfully realized in this study. This design philosophy and preparative technique will provide support for the design and construction of new types of special nanostructures with multi-functionality.

AB - We study the adhesion, friction and leak rate of seals for four different elastomers: Acrylonitrile Butadiene Rubber (NBR), Ethylene Propylene Diene (EPDM), Polyepichlorohydrin (GECO) and Polydimethylsiloxane (PDMS). Adhesion between smooth clean glass balls and all the elastomers is studied both in the dry state and in water. In water, adhesion is observed for the NBR and PDMS elastomers, but not for the EPDM and GECO elastomers, which we attribute to the differences in surface energy and dewetting. The leakage of water is studied with rubber square-ring seals squeezed against sandblasted glass surfaces. Here we observe a strongly non-linear dependence of the leak rate on the water pressure DeltaP for the elastomers exhibiting adhesion in water, while the leak rate depends nearly linearly on DeltaP for the other elastomers. We attribute the non linearity to some adhesion-related phenomena, such as dewetting or the (time dependent) formation of gas bubbles, which blocks fluid flow channels. Finally, rubber friction is studied at low sliding speeds using smooth glass and sandblasted glass as substrates, both in the dry state and in water. The measured friction coefficients are compared to theory, and the origin of the frictional shear stress acting in the area of real contact is discussed. The NBR rubber, which exhibits the strongest adhesion both in the dry state and in water, also shows the highest friction both in the dry state and in water.

AB - The average structure and the local structure of nanocrystalline Rh-doped CeO2 catalysts, prepared using a co-precipitation method, were studied using a set of structural (PDF, HRTEM, XRD) and spectral (XPS, Raman spectroscopy) methods. The samples with Rh content less than 10 wt%, calcined at 450 degrees C, were homogeneous solid solutions. A comparison of the experimental results and Pair distribution function (PDF) modeling data showed that Rh3+ substitutes Ce4+ ions in the fluorite phase. Charge equilibrium is obtained by the oxygen vacancy for each Rh3+ cation introduced into the ceria cell. The solid solution demonstrated high catalytic activity in low-temperature CO oxidation (LTO CO). The solid solutions were stable only in a nanocrystalline state and decomposed upon thermal treatment. The calcination of the solid solution at T > 450 degrees C results in a decrease in the catalytic activity that is accompanied by Rh association in the subsurface area and strong distortion of the anionic subcell. At T = 800 degrees C alpha-Rh2O3 nanoparticles are formed on the surface of the fluorite phase. The XRD-detectable Rh oxide phases are formed after calcination at 1000 degrees C. However, some parts of Rh within the subsurface RhxCe1-xO2-delta solid solution remain and they preserve catalytic properties for low-temperature oxidation.

AB - Two 3D solvent-stable zinc(ii)-lanthanide(iii) heterometallic metal-organic frameworks (MOFs) {[(CH3)2NH2]2[Zn2Ln2(FDA)6(DMF)2].2DMF}n [Ln = Eu (Zn-Eu) and Tb (Zn-Tb); H2FDA = furan-2,5-dicarboxylic acid] based on Zn2Ln2(COO)10 tetrametallic clusters and furan-2,5-dicarboxylic acid have been successfully synthesized. These MOFs can serve as luminescent sensors for the fast response and highly selective detection of aniline via luminescence quenching. More importantly, a linear correlation is observed between their luminescence and the low concentration of aniline and the detection limits of aniline are 7.5 MUmol L 1 for Zn-Eu and 5.2 MUmol L-1 for Zn-Tb.

AB - The prodrug or caged-luciferin strategy affords an excellent platform for persistent bioluminescence imaging. In the current work, we designed and synthesized ten novel pro-substrates for Renilla luciferase by introducing ester protecting groups of different sizes into the carbonyl group of the free luciferin 1. Taking advantage of intracellular esterases, lipases, and nucleophilic substances, the ester protecting groups were hydrolyzed, resulting in the release of a free luciferin and a bioluminescence signal turn-on. Among the tested pro-substrates, the butyryloxymethyl luciferin 7 exhibited low cytotoxicity and a prolonged luminescence signal both in cellulo and in vivo. Therefore, the butyryloxymethyl luciferin 7 can act as a promising substrate for noninvasive extended imaging in diagnostic and therapeutic fields. PMID- 29177294 TI - Elucidating the stability of bolaamphiphilic polypeptide nanosheets using atomistic molecular dynamics. AB - Atomistic molecular dynamics was employed to characterize the stability of nanosheets formed by bolaamphiphilic polypeptides. Two different nanosheets (based on RFL4FR and EFL4FE peptide sequences) were simulated to quantify the impact of the bolaamphiphilic nature of the peptides on the structure and energetics of the formed nanostructures. Our results corroborate the structural results obtained experimentally, indicating consistent values for the separation between the peptide planes as well as for nanosheet thickness. Energy analysis indicates that in general the stability of the nanosheets is dominated by electrostatic interactions and nanosheet-water environment interactions contribute considerably to stability. In general, the nanosheets were found to be very stable especially the EFL4FE system that presents a greater energy of interaction between the components of the system. PMF calculations indicate that the free energy required to remove a peptide from the nanosheet is greater than 250 kJ mol-1 reaching the highest value of 310 kJ mol-1 for the extraction of the peptide in the EFL4FE nanosheet.

AB - Gallium-68 (68Ga) has been the subject of increasing interest for its potential in the production of radiotracers for diagnosis of diseases. In this work we report the complexation of 68Ga by the amino acid based tripodal chelate H3Dpaa, and two bifunctional derivatives, H3Dpaa.dab and H4Dpaa.ga, under a range of conditions with particular emphasis on the rapid complexation of 68Ga at pH 7.4. 100 MUM H3Dpaa achieved a radiochemical yield of 95% at pH 7.4 in 5 minutes at 37 degrees C. The bifunctional derivatives H4Dpaa.ga and H3Dpaa.dab achieved 94% and 84% radiochemical yields, respectively, under the same conditions. The resulting Ga(iii) complexes show thermodynamic stabilities of log KGaDpaa = 18.53, log KGaDpaa.dab = 22.08, log KGaDpaa.ga = 18.36. Unfortunately, the resulting radiolabelled species do not present sufficient serum stability for in vivo application. Herein we show a flexible synthesis for bifunctional chelators based on amino acids that rapidly complex 68Ga under physiological conditions.

AB - We present a novel, self-assembled nanostructure with selective photocatalytic activity formed from anionic polyoxometalate clusters and cationic dendrimers by electrostatic self-assembly. The association of the components in aqueous solution is driven by ionic interaction and steric factors yielding stable aggregates of a defined size with a coil-like structure. The assemblies show high potential for the application in solar-energy conversion systems due to their enhanced and substrate specific photocatalytic activity.

AB - A flexible Sb2O3/carbon cloth (CC) composite is synthesized using a simple solvothermal method. The Sb2O3/CC composite exhibits higher capacity and capacity retention of alloying and conversion reactions as an anode for sodium ion batteries, attributed to the good conductivity of CC and strong chemical bonds between Sb2O3 and CC.

AB - Incorporating photosensitive molecules into the organic/inorganic hybrid materials can contribute to forming photoresponsive systems. The second/third order nonlinear optical properties can be changed via external light stimulation at an appropriate wavelength. The photochromic metal complexes appear to be superior promising materials in the domain of photoswitchable nonlinear optics (NLO). Thus, the purpose of this review is to examine current progress of metal complexes in the field of photoswitchable NLO materials and provide perspectives for the future. The overview includes the second-order and third-order NLO photoswitches and NLO properties of metal complexes. Combined with the characteristics of pyrene and stilbazolium groups, we describe a new type of photoswitchable NLO materials. The rapidly increasing investigations in this domain suggest that NLO photoswitches of metal complexes would play a critical role for inspiring applications in the future.

AB - 6,7-Dihydro-5H-dibenz[c,e]azepines, a class of secondary amine incorporating a centre-axis chirality relay, can be prepared from N-(2-bromobenzyl)-N-(1 arylalkyl)methanesulfonamides via Pd-catalysed intramolecular direct arylation, and methylated at C(7) via the 5,7-trans diastereoselective addition of methylmagnesium bromide to the derived N-benzylazepinium tetraphenylborate. Using these methods, the 4,5-dimethylated and 4,5,7-trimethylated homologues 13 and 14 were obtained and shown by 1H NMR spectroscopy to be axially biased in opposite senses, as defined by the respective pseudoaxial or pseudoequatorial orientation of the 5-substituent in the preferred conformers, while retaining their tropos nature (the Arrhenius activation energy, EA, for the conformational exchange process in 14 was estimated to be 57 kJ mol-1 using 2D-EXSY NMR spectroscopy at 233-248 K). These results serve to illustrate how substituent effects might be exploited in new designs of bridged biaryl ligand in which tropos dynamics operate in combination with a pre-existing axial stereochemical bias. PMID- 29177300 TI - Towards a dissociative SPC-like water model - probing the impact of intramolecular Coulombic contributions. AB - The dissociative water potential introduced by Garofalini et al. proved to be a simple and effective description to account for proton transfer in aqueous media, enabling for instance the execution of simulation studies at different pH values. In this model the charge of each particle is represented by a point-charge surrounded by a Gaussian charge-cloud of opposite sign, thus four Coulombic terms (point-charge-point-charge, point-charge-charge-cloud, charge-cloud-point-charge and charge-cloud-charge-cloud) are required per atom pair. In this work it is demonstrated that the Gaussian charge distributions can be removed from the model after a minor modification of the overall atomic point-charges. Despite this substantial modification of the model, structural properties obtained via pair- and angle distributions remain largely unaffected and the change in dynamical properties (vibrational frequencies, proton transfer properties) was found to be minor. As an additional improvement an adjustment of the bending mode vibration was carried out by carefully evaluating the parametrization of the three-body interaction potential, thereby retaining the good agreement of the transfer properties of the aqueous excess proton reported in an earlier study. The proposed simple point-charge (SPC) type parametrization of the Coulombic interactions not only leads to a notable decrease in computational demand but generalizes the dissociative model by improving its transferability to established third-party simulation software and enabling the application of different theoretical approaches such as Ewald summation techniques not considered in the original parametrization. The outlined optimization strategy demonstrates that despite the complex and challenging formulation of the force field, various dynamical properties can be selectively adjusted without influencing other critical parameters of the simulated systems. PMID- 29177301 TI - Photoresponsive ruthenium-containing polymers: potential polymeric metallodrugs for anticancer phototherapy. AB - This Frontier presents the recent development of photoresponsive Ru-containing polymers for cancer treatment. These novel Ru-containing polymers are prepared by introducing photoresponsive Ru complexes into polymers. Based on their chemical structures in aqueous solutions, these polymers can self-assemble into different nanostructures. The self-assembled nanostructures can circulate in the blood stream, accumulate at tumor tissue, and can be taken up by tumor cells. Red light, which can penetrate into tissue deeply, can induce the photodissociation of these polymers and sensitize singlet oxygen (1O2) generation. Both dissociated Ru complexes and generated 1O2 can inhibit the growth of tumor cells. Photoresponsive Ru-containing polymers provide a new platform for combined photodynamic therapy and photoactivated chemotherapy. The design strategies, self assembly, photoresponsiveness, and anticancer effects of these polymers are introduced. Some remaining challenges for Ru-containing polymers for phototherapy are discussed. PMID- 29177302 TI - A specific HeLa cell-labelled and lysosome-targeted upconversion fluorescent probe: PEG-modified Sr2YbF7:Tm3+ . AB - In this study, water-soluble PEG-modified Sr2YbF7:Tm3+ was prepared conveniently by a one-pot solvothermal method, where the molar ratio of Sr2+ to Yb3+ was controlled between 3 : 2 and 1 : 1. The optimum red-light emission at 677-699 nm was modulated via 0.7% Tm3+ doped under irradiation at 980 nm. Interestingly, biological experimental results showed that the PEG-modified Sr2YbF7:Tm3+ with low toxicity, excellent cell membrane permeability and high photostability can not only distinguish HeLa cells from mouse embryonic fibroblasts but also target the subcellular organelle lysosome in HeLa cells; therefore it can be anticipated that the as-prepared material would be a potential tool for cancer diagnosis. PMID- 29177303 TI - Reducing the photocatalysis induced by hot electrons of plasmonic nanoparticles due to tradeoff of photothermal heating. AB - Silver nanotetrahedron (AgNT) two-dimensional arrays on a glass substrate generate nonthermal hot electrons, which induced photocatalytic oxidation of 4,4 dimercaptoazobenzene (DMAB) adsorbed onto its surface. The rate of the photocatalytic oxidation of DMAB is found to decrease upon increasing the intensity of the excitation light, unlike traditional photocatalysis reactions. The amount of 4-nitrothiophenol (4-NTP) resulting from the photocatalytic oxidation of DMAB is lower than expected, suggesting the partial desorption of DMAB or 4-NTP molecules from the surface of the AgNTs. However, the hot electrons remaining from the photocatalysis reaction thermalize and transfer their energy to the nanoparticle lattices, generating heat. The photothermal heat is sufficient to dissociate the Ag-S bond causing desorption of both DMAB and 4-NTP.

AB - We report a transition metal-free dehalogenation of vicinal dihalo compounds by 1,1'-bis(trimethylsilyl)-1H,1'H-4,4'-bipyridinylidene (1) under mild conditions, in which trimethylsilyl halide and 4,4'-bipyridine were generated as byproducts. The synthetic protocol for this dehalogenation reaction was effective for a wide scope of dibromo compounds as substrates while keeping the various functional groups intact. Furthermore, the reduction of vicinal dichloro alkanes and vicinal dibromo alkenes also proceeded in a salt-free manner to afford the corresponding alkenes and alkynes.

PMID- 29177306 TI - Remediation mechanisms for Cd-contaminated soil using natural sepiolite at the field scale. AB - Remediation of heavy metal polluted agricultural soil is essential for human health and ecological safety and remediation mechanisms at the microscopic level are vital for their large-scale utilization. In this study, natural sepiolite was employed as an immobilization agent for in situ field-scale remediation of Cd contaminated paddy soil and the remediation mechanisms were investigated in terms of soil chemistry and plant physiology. Natural sepiolite had a significant immobilization effect for bioavailable Cd contents in paddy soil, and consequently could lower the Cd concentrations of brown rice, husk, straw, and roots of rice plants by 54.7-73.7%, 44.0-62.5%, 26.5-67.2%, and 36.7-46.7%, respectively. Regarding soil chemistry, natural sepiolite increased the soil pH values and shifted the zeta potentials of soil particles to be more negative, enhancing the fixation or sorption of Cd on soil particles, and resulted in the reduction of HCl and DTPA extractable Cd concentrations in paddy soil. Natural sepiolite neither enhanced nor inhibited iron plaques on the rice root surface, but did change the chemical environments of Fe and S in rice root. Natural sepiolite improved the activities of antioxidant enzymes and enhanced the total antioxidant capacity to alleviate the stress of Cd. It also promotes the synthesis of GSH and NPT to complete the detoxification. In general, the remediation mechanisms of natural sepiolite for the Cd pollutant in paddy soil could be summarized as the collective effects of soil chemistry and plant physiology. PMID- 29177307 TI - Physicochemical stability, antioxidant properties and bioaccessibility of beta carotene in orange oil-in-water beverage emulsions: influence of carrier oil types. AB - This study investigated the effect of carrier oils (short-chain triglycerides (SCT) vs. long-chain triglycerides (LCT)) on the physical stability, chemical degradation, antioxidant properties and bioaccessibility of beta-carotene-loaded orange oil-in-water beverage emulsions. Beverages formulated with 50% LCT (corn oil) were physically more stable compared to the ones with 50% SCT (tributyrin) as indicated by the Turbiscan 32 Stability Indices during chilled storage for 28 days. No chemical degradation of beta-carotene was observed during storage regardless of the carrier oil composition. The formation of primary (conjugated dienes) or secondary (thiobarbituric acid reactive substances) oxidation products at the end of the storage period was insignificant. The bioaccessibility of beta carotene was significantly affected (P < 0.05) by the type of carrier oil and decreased in the following order: 50% LCT + 50% orange oil > 50% SCT + 50% orange oil > 100% orange oil. The high bioaccessibility of beta-carotene (30.06%) in the beverages formulated with LCTs was attributed to the enhanced solubilisation capacity of the lipophilic carotenoid in mixed micelles after the in vitro digestion protocol. PMID- 29177308 TI - Discovery of IDO1 and DNA dual targeting antitumor agents. AB - The development of small molecules for cancer immunotherapy is highly challenging and indoleamine 2,3-dioxygenase 1 (IDO1) represents a promising target. Inspired by the synergistic effects between IDO1 inhibitors and traditional antitumor chemotherapeutics, the first orally active dual IDO1 and DNA targeting agents were designed by the pharmacophore fusion strategy. The bifunctional hybrids exhibited enhanced IDO1 enzyme inhibitory activity and in vitro cytotoxicity as compared to IDO1 inhibitor 1-methyl-tryptophan and DNA alkylating agent melphalan. In a murine LLC tumor model, the dual targeting agents demonstrated excellent antitumor efficacy, highlighting the advantages of this novel design strategy to improve the efficacy of small molecule cancer immunotherapy. PMID- 29177309 TI - Horizontal drying fronts in films of colloidal dispersions: influence of hydrostatic pressure and collective diffusion. AB - The origin and time evolution of heterogeneities in drying colloidal films is still a matter of debate. In this work, we studied the behaviour of horizontal drying fronts in a 1D configuration. The effects of hydrostatic pressure and collective diffusion of charged particles, neglected so far, were introduced. We made use of the new simulation tool based on cellular automata we recently presented (Langmuir 2015 & 2017). To check the simulation results, measurements of film profiles in the wet state and drying front velocities were performed with silica colloids. It was shown that taking hydrostatic pressure into account much improves agreement between theory and experiment. On the other hand, the simulation showed that collective diffusion slows down the drying fronts, even more when the Debye length is increased. This latter effect remains to be checked experimentally. This work opens the way to further improvements of theory and simulation, notably 2D and 3D simulations. PMID- 29177310 TI - Non-Gaussian elasticity and charge density-dependent swelling of strong polyelectrolyte poly(N-isopropylacrylamide-co-sodium acrylate) hydrogels. AB - The mechanical properties and charge density-dependent swelling of strong polyelectrolyte poly(N-isopropylacrylamide-co-sodium acrylate) P(NIPA-co-NaA) hydrogels prepared at a fixed total monomer concentration and crosslinker ratio, but at various charge densities, i.e. NaA content in the feed between 0 and 90 mol%, were investigated. The elasticity results were discussed to explain the relationship between the elastic free energy DeltaGel and the swelling ratio alpha as well as to fit the existing theories to the swelling data. The implications of the obtained results for the deviation from the Gaussian chain statistics were considered. Given the swollen elastic modulus and the dependence of charge density on the equilibrium gel volume, it would seem that the latter factor is an important determinant of non-Gaussian elasticity of polyelectrolyte P(NIPA-co-NaA) hydrogels containing strongly dissociated groups. The dependence of the reduced modulus on the equilibrium gel volume was found to be Gr ~ (Veq) 0.47 at low swelling degree and Gr ~ (Veq)0.64 at high swelling degree and the deviation was interpreted as the non-Gaussian elasticity of equilibrium swollen P(NIPA-co-NaA) hydrogels. The detailed theoretical treatments of non-Gaussian elasticity of P(NIPA-co-NaA) hydrogels and, in particular, the influence of the charge density on the elasticity showed that the knowledge of several swollen state parameters and the effective charge density distribution of hydrogels were strongly required to explain the variation of the elastic properties depending on the ionic group content. Within this framework, the dominant mechanism responsible for the deviation from Gaussian elasticity and the finite chain extensibility of ionic P(NIPA-co-NaA) hydrogels was described and the results were used to explain the dependence of the elastic modulus on the equilibrium gel volume. PMID- 29177311 TI - Insight into the effect mechanism of urea-induced protein denaturation by dielectric spectroscopy. AB - Dielectric relaxation spectroscopy was applied to study how urea affects the phase transition of a thermosensitive polymer, poly(N-isopropylacrylamide) (PNIPAM), which has been widely used as a protein model. It was found that there is a pronounced relaxation near 10 GHz for the ternary system of PNIPAM in urea aqueous solution. The temperature dependence of dielectric parameters indicates that urea can reduce the lower critical solution temperature (LCST) of PNIPAM, i.e., stabilize the globule state of PNIPAM and collapse the PNIPAM chains. Based on our results, the interaction mechanism of urea on the conformational transition of PNIPAM was presented: urea replaces water molecules directly bonding with PNIPAM and acts as the bridging agent for the adjacent side chains of PNIPAM. Accordingly, the mechanism with which urea denatures protein was deduced. In addition, it is worth mentioning that, from the temperature dependence of the dielectric parameters obtained in the presence of urea, an interesting phenomenon was found in which the effect of urea on PNIPAM seems to take 2 M as a unit. This result may be the reason why urea and TMAO exit marine fishes at a specific ratio of 2 : 1.

During the past three years, we have witnessed the rapid development of sustainable and practical C-C and C-H bond functionalization by means of long-distance 1,n radical migration (n = 4, 5, 6) events. Its advent brings our chemical community a new platform to deal with the challenging migration transformations and thus complements the existing ionic-type migration protocols. In this review, the recent achievements in distal radical migration triggered C-C and C-H bond functionalization are summarized.

It is an ensemble of nanobuildings, and the height of each nanobuilding is greater than its depth. Plasmonic nanocity exhibits a vertical resonance mode in addition to distal longitudinal and proximal longitudinal resonance modes, such that it can be applied to chromatic angular polarizers, sophisticated image recording, and high density data storage. Further growth of nanobuildings to bulky and tall nanocuboids leads to asymmetric and dichroic scattering, which can be applied in security printing. PMID- 29177316 TI - Rat ceruloplasmin: a new labile copper binding site and zinc/copper mosaic. AB - Ceruloplasmin (Cp) is a copper-containing multifunctional oxidase of plasma, an antioxidant, an acute-phase protein and a free radical scavenger. The structural organization of Cp causes its sensitivity to proteolysis and ROS (reactive oxygen species), which can alter some of the important Cp functions. Elucidation of the orthorhombic crystal structure of rat Cp at 2.3 A resolution revealed the basis for stronger resistance of rat Cp to proteolysis and a new labile copper binding site. The presence of this site appears as a very rare and distinctive feature of rat Cp as was shown by sequence alignment of ceruloplasmin, hephaestin and zyklopen in the Deuterostomia taxonomic group. The trigonal crystal form of rat Cp at 3.2 A demonstrates unexpected partial substitution of copper by zinc. PMID- 29177317 TI - Unfolding of a comb-like polymer in a poor solvent: translation of macromolecular architecture in the force-deformation spectra. AB - A numerical self-consistent field modeling approach was employed to study the mechanical unfolding of a globule made by comb-like polymers in a poor solvent with the aim of unraveling how the macromolecular architecture affects the shape of the single-molecule force-deformation curves. We demonstrate that the dependence of the restoring force on the imposed extension of the main chain of the comb-like polymer exhibits a characteristic oscillatory shape in the intermediate deformation range. Theoretical arguments are developed that enable us to relate the shape of the patterns on the force-deformation curves to the molecular architecture (grafting density and length of the side chains) and interaction parameters. Thus, the results of our study suggest a new approach for the determination of macromolecular topology from single-molecule mechanical unfolding experiments.

PMID- 29177319 TI - Specifically targeting mixed-type dimeric G-quadruplexes using berberine dimers. AB - Three polyether-tethered berberine dimers (1a-c) were studied for their binding affinity, selectivity and thermal stabilization towards human telomeric dimeric quadruplex DNA (G2T1). Compound 1a with the shortest polyether linker showed the highest affinity (Ka > 108 M-1) and 76-508-fold higher selectivity for mixed-type G2T1 over antiparallel G2T1 and three monomeric G-quadruplexes, which are human telomeric monomeric quadruplex G1, c-kit 1 and c-kit 2. Compound 1a induced the formation of quadruplex structures and showed higher thermal stabilization for mixed-type G2T1 than for anti-parallel G2T1, G1 and ds DNA. Spectroscopic studies suggest that compound 1a could bind to mixed-type G2T1 via end-stacking and external binding modes. These results suggest that the polyether linkers in these compounds play an important role in regulating the binding affinity and selectivity towards mixed-type G2T1 and that compound 1a could target mixed-type G2T1 at other genome regions with antiparallel G2T1 and monomeric G-quadruplexes. These results may provide useful guidance for the rational design of selective multimeric G-quadruplex binders and potential anticancer agents. PMID- 29177324 TI - Tuning the inter-molecular charge transfer, second-order nonlinear optical and absorption spectra properties of a pi-dimer under an external electric field. AB - In this work, we applied an external electric field (F) to a biphenalenyl derivative (BN-PLY2) in the direction of the negative z-axis (F-z) and the positive z-axis (F+z), respectively. The influence of the two directions of F on the molecular structures and electronic properties is investigated, which gives interesting results. Density functional theory (DFT) calculations show that the application of F-z (F-z = 0 to -190 * 10-4) is an advantage toward improving pi dimer stability, which is attributed to an increase in bonding and attractive electrostatic interactions. Interestingly, a large amount of negative charge is induced by applying F-z to the upper layer, resulting in an increase in the electron density in the upper layer, which is the main factor for the formation of a symmetric highest occupied molecular orbital (HOMO) at F-z = -180 * 10-4 au (-9.26 * 109 V m-1). Moreover, when F+z is applied, the HOMO and HOMO-1 undergo orbital interchange in the pi-dimer at F+z = 100/110 * 10-4 au. Significantly, the effect of the external electric field effectively regulates the first hyperpolarizabilities (betatot). When the F+z ranges from 0 to 140 * 10-4 au, the betatot values slightly decrease to 0 au. Note that, upon increasing F+z, the betatot values sharply increase to 6.67 * 103 au (F+z = 190 * 10-4 au). Furthermore, the evolutions of the absorption spectra under F might well explain the trend of betatot values. When the F+z ranges from 0 to 140 * 10-4 au, the broad absorption spikes with a low-energy are significantly blue-shifted, while only absorption spikes with a high-energy are significantly red-shifted (F+z = 140 to 190 * 10-4 au). The present work not only provides a deeper understanding of the relationships between the molecular structure and the electronic properties of a pi-dimer system, but can also be developed for designing highly efficient nonlinear optical materials through the influence of an external electric field.

PMID- 29177326 TI - Surface-enhanced Raman scattering II: concluding remarks. AB - Surface-enhanced Raman scattering (SERS) enables the detection of a large number of different adsorbates at extraordinarily low levels. This plasmonics-based technology has undergone a number of remarkable advances since its discovery over 40 years ago, and has emerged from being an investigative tool confined largely to the research laboratory into a much more usable tool across a broad range of investigative studies, both within the laboratory and beyond. The purpose of this Concluding remarks manuscript is to capture, at least in part, the developments in this area since the first Faraday discussion of SERS over a decade ago. It begins with a brief contextual overview and then moves into describing a few of the many highlights from the meeting. Along the way, we have added a few comments and perspectives as a means to more fully stage where the different areas of research with SERS stand today. An addendum is included that collects a few of the recent perspectives on the original work and activities in this area. PMID- 29177327 TI - Effects of the SrTiO3 support on visible-light water oxidation with Co3O4 nanoparticles. AB - The photocatalytic activity of SrTiO3 modified with Co3O4 nanoparticles for water oxidation under visible light (lambda > 480 nm) was investigated with respect to the physicochemical properties of the SrTiO3 support. SrTiO3 was synthesized by a polymerized complex method or a hydrothermal method, followed by calcination in air at different temperatures in order to obtain SrTiO3 particles having different sizes. Co3O4 nanoparticles, which provide both visible light absorption and water oxidation centers, were loaded on the as-prepared SrTiO3 by an impregnation method using Co(NO3)2 as the precursor, followed by heating at 423 K in air. Decreasing the SrTiO3 particle size (that is, improving the crystallinity) enhanced the photocatalytic activity by promoting the formation of Co3O4 nanoparticles that provided optimal light absorption and catalytic sites. However, Co3O4 aggregation occurred on overly large SrTiO3 particles, leading to a decrease in activity. This study demonstrates the possibility of tuning the photocatalytic activity of a Co3O4-loaded wide-gap semiconductor for visible light water oxidation through the appropriate selection of the support material.

AB - A series of hydroxycyclopent-2-enones and methoxycyclopent-2-enones have been synthesized in a single operation from simple furan substrates using an innovative continuous flow nebulizer system (NebPhotOX). Photooxygenation of the furan substrates takes place in an aerosol within the NebPhotOX system.

AB - The combination of photodynamic therapy (PDT) and photothermal therapy (PTT) is highly desired to improve the cancer phototherapeutic effect. However, most reported multicomponent therapeutic agents need complex preparation processes and must be excited by using multiple light sources. Herein, triphenylamine flanked furan-diketopyrrolopyrrole (FDPP-TPA) with a donor-acceptor-donor structure has been synthesized and used as a sole-component agent for fluorescence, photoacoustic and photothermal imaging guided photodynamic and photothermal synergistic therapy. FDPP-TPA nanoparticles (NPs) obtained by re-precipitation exhibit a high molar extinction coefficient (epsilon = 2.13 (+/-0.2) * 104 M-1 cm 1), excellent photothermal conversion efficiency (eta = 47%) and favorable singlet oxygen quantum yield (PhiDelta(X) = 40%). In vitro, the half-maximal inhibitory concentration (IC50) is 13 MUg mL-1 determined by cytotoxicity assay. And the apoptosis rate is 67.3% according to flow cytometry analysis. In vivo, the tumor can be completely ablated without recurrence, which suggests that FDPP TPA NPs can generate considerable poisonous singlet oxygen and hyperthermia for tumor treatment.

AB - New materials exhibiting reversible structural transitions are desired for a variety of applications, yet they are difficult to identify and stabilize. Monolayer MoTe2 has emerged as a good candidate as it displays a small energy difference between a semiconducting H and semimetallic T' phase; however, switching between the two phases is difficult. Here, we propose using chalcogen alloying to overcome this challenge. Using first principles density functional theory calculations, we investigate 7 MoTe2-xXx alloys (X = N, P, Sb, F, Br, I, and Se) at three concentrations. We find that the energy difference between the H and T' phases is dependent on the chemistry, size, and concentration of the dopant atom, providing significant control over the stability of the two phases. From the thermodynamic stability of these compounds, we show that several can be stabilized under the appropriate experimental conditions. We also find that P alloying enhances the chemical reactivity of the basal plane towards a variety of adsorbates. Finally, we show that mechanical strain makes it is easier to stabilize and dynamically switch between the two states than in unalloyed MoTe2. Our results suggest that Te substitution in monolayer MoTe2 is a way to induce and control a reversible structural phase transition in this two-dimensional material system.

AB - Biological membranes are remarkably heterogeneous, composed of diverse lipid mixtures with distinct chemical structure and composition. By combining molecular dynamics simulations and the newly developed Lipid-Force Distribution Analysis (L FDA), we explore force transmission in complex multi-component membrane models mimicking eukaryotic organelles. We found that the chemical-moiety based segmentation at membrane interfaces revealed a distinctive distribution of bonded and non-bonded forces in diverse membrane environment. Our molecular stress analysis could have far-reaching implications in describing the relationship between membrane mechanical properties and functional states of chemically distinct lipids. PMID- 29177332 TI - NiCo2S4 nanosheet-decorated 3D, porous Ni film@Ni wire electrode materials for all solid-state asymmetric supercapacitor applications. AB - Wire type supercapacitors with high energy and power densities have generated considerable interest in wearable applications. Herein, we report a novel NiCo2S4 decorated 3D, porous Ni film@Ni wire electrode for high performance supercapacitor application. In this work, a facile method is introduced to fabricate a 3D, porous Ni film deposited on a Ni wire as a flexible electrode, followed by decoration with NiCo2S4 as an electroactive material. The fabricated NiCo2S4-decorated 3D, porous Ni film@Ni wire electrode displays a superior performance with an areal and volumetric capacitance of 1.228 F cm-2 and 199.74 F cm-3, respectively, at a current density of 0.2 mA cm-1 with a maximum volumetric energy and power density (EV: 6.935 mW h cm-3; PV: 1.019 W cm-3). Finally, the solid state asymmetric wire type supercapacitor is fabricated using the fabricated NiCo2S4-decorated 3D, porous Ni film@Ni wire as a positive electrode and N-doped reduced graphene oxide (N-rGO) as a negative electrode and this exhibits good areal and volumetric capacitances of CA: 0.12 F cm-2 and CV: 19.57 F cm-2 with a higher rate capability (92%). This asymmetric wire type supercapacitor demonstrates a low leakage current and self-discharge with a maximum volumetric energy (EV: 5.33 mW h cm-3) and power (PV: 855.69 mW cm-3) density.

PMID- 29177334 TI - Large-area potassium-doped highly conductive graphene films for electromagnetic interference shielding. AB - As promising carbonaceous films, graphene films (GF) have exhibited many remarkable mechanical and electrical/thermal properties of great potential for wide functional applications. However, the electrical conductivity of GF still needs to be improved and the limitation lies in the low carrier density of pure graphene. Here, we presented a post-doping method for large-area potassium doped graphene films (GF-K) and promoted the electrical conductivity of GF approaching benchmark metals. The macroscopic-assembled GF-K shows a similar color to graphite intercalation compounds. The potassium doping increased the carrier density of the GF without undermining the electronic quality of the graphene unit. The doping concentration was optimized to prepare stage-2 GF-K (C24K) with the highest electrical conductivity (1.49 * 107 S m-1), holding merits of low density (1.63 g cm-3), and high flexibility. Doped GF with better specific electrical conductivity than copper showed outstanding electromagnetic interference shielding performance. Shielding effectiveness (SE) increased from 70-85 dB for graphene film (GF) to over 130 dB for GF-K only at 31 MUm thickness, which is among the best SEs in previous reports. The combination of high specific conductivity, mechanical flexibility, high EMI SE, light weight, and facile productivity enables GF-K to be promising in many high-end EMI applications such as aerospace and wearable devices. PMID- 29177335 TI - Molecular actions of hypocholesterolaemic compounds from edible mushrooms. AB - Cholesterol levels are strictly regulated to maintain its homeostasis; therefore, if it is not absorbed with the diet, the cholesterol biosynthetic pathway is enhanced and vice versa. Nowadays, the commonly prescribed therapeutic treatments for hypocholesterolemic patients are targeted toward the reduction of both cholesterol intestinal absorption and/or its endogenous biosynthesis. But, when hypercholesterolemia is still moderate the consumption of food products with cholesterol-lowering capacities is more desirable than using drugs. Marketed foods supplemented with hypocholesterolemic compounds are only inhibiting mechanisms for cholesterol absorption (i.e. phytosterols and cereal beta glucans). However, certain fungal extracts obtained from edible mushrooms might be able to modulate cholesterol levels by both strategies, pharmaceutical drugs and functional foods. In vitro and in vivo studies indicated that fungal sterols down-regulated genes involved in cholesterol homeostasis (such as Srebf2 and Nr1h4 (FXR)) and other specific mushroom extracts (beta-glucans and other water soluble compounds) also stimulated transcriptional profiles similar to simvastatin or ezetimibe (two hypocholesterolemic drugs). These and other observations suggested that the hypocholesterolemic effect of mushroom extracts could be due to transcriptional and post-transcriptional modulations besides other indirect effects. PMID- 29177336 TI - New insight into an efficient visible light-driven photocatalytic organic transformation over CdS/TiO2 photocatalysts. AB - Selective transformation of organics by visible-light-driven photocatalysis has been considered as a green and efficient strategy for the synthesis of fine chemicals. Herein, we fabricated mesoporous structured TiO2 with CdS nanoparticles successfully by a photodeposition method. The photocatalytic selective oxidation of benzyl alcohols and reduction of 4-nitroaniline were demonstrated over the as-prepared samples under visible-light irradiation. The CdS-decorated TiO2 with the photodeposition time of 90 min exhibited highest activity, which was higher than that of the commercial CdS, bare TiO2, CdS/P25, and CdS/SiO2. Further experimental results indicated that the higher performance was attributed to the moderate deposition of CdS forming a closely connected heterojunction with TiO2, which promoted the separation of photogenerated electrons and holes. Based on the results of active species detection, possible mechanisms for photocatalytic selective oxidation of benzyl alcohol and reduction of 4-nitroaniline were proposed. Our study may provide guidance for selective transformation of organics via construction of heterojunction photocatalysts. PMID- 29177337 TI - Lower lattice thermal conductivity in SbAs than As or Sb monolayers: a first principles study. AB - Phonon transport in group-VA element (As, Sb and Bi) monolayer semiconductors has been widely investigated in theory, and, of them, monolayer Sb (antimonene) has recently been synthesized. In this work, phonon transport in monolayer SbAs is investigated with a combination of first-principles calculations and the linearized phonon Boltzmann equation. It is found that the lattice thermal conductivity of monolayer SbAs is lower than those of both monolayer As and Sb, and the corresponding sheet thermal conductance is 28.8 W K-1 at room temperature. To understand the lower lattice thermal conductivity in monolayer SbAs than those in monolayer As and Sb, the group velocities and phonon lifetimes of monolayer As, SbAs and Sb are calculated. The calculated results show that the group velocities of monolayer SbAs are between those of monolayer As and Sb, but that the phonon lifetimes of SbAs are smaller than those of both monolayer As and Sb. Hence, the low lattice thermal conductivity in monolayer SbAs is attributed to very small phonon lifetimes. Unexpectedly, the ZA branch has very little contribution to the total thermal conductivity, only 2.4%, which is obviously different from those of monolayer As and Sb with very large contributions. This can be explained by very small phonon lifetimes for the ZA branch of monolayer SbAs. The lower lattice thermal conductivity of monolayer SbAs compared to that of monolayer As or Sb can be understood by the alloying of As (Sb) with Sb (As), which should introduce phonon point defect scattering. We also consider the isotope and size effects on the lattice thermal conductivity. It is found that isotope scattering produces a neglectful effect, and the lattice thermal conductivity with a characteristic length smaller than 30 nm can reach a decrease of about 47%. These results may offer perspectives on tuning the lattice thermal conductivity by the mixture of multiple elements for applications of thermal management and thermoelectricity, and motivate further experimental efforts to synthesize monolayer SbAs. PMID- 29177338 TI - Mapping of exciton-exciton annihilation in MEH-PPV by time-resolved spectroscopy: experiment and microscopic theory. AB - Transient absorption traces taken on samples of the polymer MEH-PPV are measured as a function of the laser intensity. In increasing the laser power, different decay dynamics of the signal are obtained. This suggests that effective exciton exciton annihilation takes place. The signals are interpreted using a microscopic quantum mechanical model. The analysis points at an ultrafast excitonic decay via interchain and intrachain annihilation, where the latter process is roughly thirty times slower. Afterwards, diffusion-induced annihilation and relaxation become effective and thus determine the long-time behavior of the excited-state decay. PMID- 29177339 TI - Adaptable piezoelectric hemispherical composite strips using a scalable groove technique for a self-powered muscle monitoring system. AB - Contrary to traditional planar flexible piezoelectric nanogenerators (PNGs), highly adaptable hemispherical shape-flexible piezoelectric composite strip (HS FPCS) based PNGs are required to harness/measure non-linear surface motions. Therefore, a feasible, cost-effective and less-time consuming groove technique was developed to fabricate adaptable HS-FPCSs with multiple lengths. A single HS CSPNG generates 130 V/0.8 MUA and can also work as a self-powered muscle monitoring system (SP-MMS) to measure maximum human body part movements, i.e., spinal cord, throat, jaw, elbow, knee, foot stress, palm hand/finger force and inhale/exhale breath conditions at a time or at variable time intervals.

PMID- 29177343 TI - Intrinsic anionic rearrangement by extrinsic control: transition of RS and CRS in thermally elevated TiN/HfO2/Pt RRAM. AB - The sneak path problem is one of the major hindrances to the application of high density crossbar resistive random access memory; however, complementary resistive switching (CRS) is an effective solution to this problem. The co-existence of resistive switching (RS) and CRS is possible within the same device. Therefore, a precise control is highly required for the successful utilization of different modes. In this study, we have demonstrated an effective way to control both switching modes in a simple HfO2-based crossbar device. The interchange between RS and CRS modes is possible, based on the intrinsic anionic rearrangement by controlling the extrinsic stimulation, either in the form of voltage or in the form of current. In particular, a highly nonlinear CRS mode is reported, in which the nonlinearity is almost 100 times greater than in the RS mode, which is achieved at a high temperature of 150 degrees C. The procedure reported in this study may be useful for the other resistive memory systems. PMID- 29177344 TI - Robust oil-core nanocapsules with hyaluronate-based shells as promising nanovehicles for lipophilic compounds. AB - The design of nanodelivery systems has been recently considered as a solution to the major challenge in pharmaceutical research - poor bioavailability of lipophilic drugs. Nanocapsules with liquid oil cores and shells based on amphiphilic polysaccharides were developed here as robust carriers of hydrophobic active compounds. A series of modified charged hyaluronates were synthesized and used as stabilizing shells ensuring also the biocompatibility of the nanocapsules that is crucial for applications related to the delivery of lipophilic drugs in vivo. Importantly, the oil nanodroplets were found to be stably suspended in water for at least 15 months without addition of low molar mass surfactants. Moreover, their size and stability may be tuned by varying the relative content of hydrophobic and hydrophilic groups in the hyaluronate derivatives as was confirmed by dynamic light scattering and nanoparticle tracking analysis as well as electron microscopy. In vivo studies demonstrated that hyaluronate-based nanocapsules accumulated preferentially in the liver as well as in the lungs. Moreover, their accumulation was dramatically potentiated in endotoxemic mice. In vitro studies showed that the nanocapsules were taken up by liver sinusoidal endothelial cells and by mouse lung vascular endothelial cells. Importantly, the capsules were found to be nontoxic in an acute oral toxicity experiment even at a dose of 2000 mg per kg b.w. Biocompatible hyaluronate-based nanocapsules with liquid cores described herein represent a promising and tunable nanodelivery system for lipophilic active compounds via both oral and intravenous administration.

AB - Roasting greatly reduces the phenolic content in green coffee beans. Considering the beneficial effects of coffee polyphenols, blends containing green coffee beans are being consumed as a healthier alternative to roasted coffee. This study was aimed at assessing the absorption and metabolism of hydroxycinnamates in an instant green/roasted (35/65) coffee blend in healthy humans. Twelve fasting men and women consumed a cup of coffee containing 269.5 mg (760.6 MUmol) of chlorogenic acids. Blood and urine samples were taken before and after coffee consumption at different times and analyzed by LC-MS-QToF. Up to 25 and 42 metabolites were identified in plasma and urine, respectively, mainly in the form of sulfate and methyl derivatives, and to a lower extent as glucuronides. Un metabolized hydroxycinnamate esters (caffeoyl-, feruloyl-, and coumaroylquinic acids), hydroxycinnamic acids (caffeic, ferulic and coumaric acids) and their phase II metabolites, in addition to phase II derivatives of lactones, represented a minor group of metabolites (16.3% of the metabolites excreted in urine) with kinetics compatible with small intestine absorption. Dihydrohydroxycinnamic acids and their phase II derivatives, in addition to feruloylglycine, showed delayed kinetics due to their colonic origin and represented the most abundant group of metabolites (75.7% of total urinary metabolites). Dihydrohydroxycinnamate esters (dihydroferuloyl-, dihydrocaffeoyl- and dihydrocoumaroylquinic acids) have been identified for the first time in both plasma and urine, with microbial origin (excreted 8-12 h after coffee intake) amounting to 8% of total urinary metabolites. In conclusion, coffee polyphenols are partially bioavailable and extensively metabolized, mainly by the colonic microbiota. PMID- 29177346 TI - Softening and yielding of soft glassy materials. AB - Solids deform and fluids flow, but soft glassy materials, such as emulsions, foams, suspensions, and pastes, exhibit an intricate mix of solid- and liquid like behavior. While much progress has been made to understand their elastic (small strain) and flow (infinite strain) properties, such understanding is lacking for the softening and yielding phenomena that connect these asymptotic regimes. Here we present a comprehensive framework for softening and yielding of soft glassy materials, based on extensive numerical simulations of oscillatory rheological tests, and show that two distinct scenarios unfold depending on the material's packing density. For dense systems, there is a single, pressure independent strain where the elastic modulus drops and the particle motion becomes diffusive. In contrast, for weakly jammed systems, a two-step process arises: at an intermediate softening strain, the elastic and loss moduli both drop down and then reach a new plateau value, whereas the particle motion becomes diffusive at the distinctly larger yield strain. We show that softening is associated with an extensive number of microscopic contact changes leading to a non-analytic rheological signature. Moreover, the scaling of the softening strain with pressure suggest the existence of a novel pressure scale above which softening and yielding coincide, and we verify the existence of this crossover scale numerically. Our findings thus evidence the existence of two distinct classes of soft glassy materials - jamming dominated and dense - and show how these can be distinguished by their rheological fingerprint. PMID- 29177347 TI - Microfluidic production of degradable thermoresponsive poly(N isopropylacrylamide)-based microgels. AB - Highly monodisperse and hydrolytically degradable thermoresponsive microgels on the tens-to-hundreds of micron size scale have been fabricated based on simultaneous on-chip mixing and emulsification of aldehyde and hydrazide functionalized poly(N-isopropylacrylamide) precursor polymers. The microfluidic chip can run for extended periods without upstream gelation and can produce monodisperse (<10% particle size variability) microgels on the size range of ~30 90 MUm, with size tunable according to the flow rate of the oil continuous phase. Fluorescence analysis indicates a uniform distribution of each reactive pre polymer inside the microgels while micromechanical testing suggests that smaller microfluidic-produced microgels exhibit significantly higher compressive moduli compared to bulk hydrogels of the same composition, an effect we attribute to improved mixing (and thus crosslinking) of the precursor polymer solutions within the microfluidic device. The microgels retain the reversible volume phase transition behavior of conventional microgels but can be hydrolytically degraded back into their oligomeric precursor polymer fragments, offering potential for microgel clearance following use in vivo. PMID- 29177348 TI - Comprehensive investigations of near infrared downshift and upconversion luminescence mechanisms in Yb3+ single-doped and Er3+,Yb3+ co-doped SiO2 inverse opals. AB - Comprehensive investigations of near infrared (NIR) downshift and visible upconversion luminescence (UCL) mechanisms were carried out for Yb3+ single-doped and Er3+,Yb3+ co-doped SiO2 inverse opals under excitation at 256, 378, 520 and 980 nm. NIR emission at 976 nm from the Yb3+-O2- charge transfer state and UCL emission at 500 nm due to the cooperative emission of two Yb3+ ions were observed in SiO2:Yb3+ inverse opal upon excitation at 256 and 980 nm, respectively. The cooperative UCL of two Yb3+ ions was suppressed due to the photon trap created by the photonic band gap. For the SiO2:Er3+,Yb3+ inverse opals, NIR emission of Yb3+ at 976 nm and of Er3+ at 1534 nm were observed upon excitation at 256, 378 and 520 nm, respectively. Upon excitation at 378 and 520 nm, the 976 nm NIR emission of Yb3+ does not arise from (2H11/2/4S3/2) + 2Yb3+(2F7/2) -> Er3+(4I15/2) + 2Yb3+(2F5/2) traditional quantum cutting. The NIR emission of Yb3+ at 976 nm may be due to the Er3+(2H11/2) + Yb3+(2F7/2) -> Yb3+(2F5/2) + Er3+(4I11/2) cross relaxation energy transfer process upon excitation at 520 nm. The NIR emission of Yb3+ at 976 nm may arise from the cross-relaxation energy transfer of Er3+(4G11/2) + Yb3+(2F7/2) -> Yb3+(2F5/2) + Er3+(4F9/2) and Er3+(4F9/2) + Yb3+(2F7/2) -> Yb3+(2F5/2) + Er3+(4I13/2) upon excitation at 378 nm.

AB - The isolation of few-layer two-dimensional (2D) metal-organic framework (MOF) sheets has been achieved at an elevated solvothermal reaction temperature. The 2D porphyrin paddlewheel framework-1 (PPF-1) MOF nanosheets (NS) are ultrathin (2.5 nm) and have large lateral dimensions (over 2 MUm). The yield of PPF-1 NS was also increased to 71.7% with increasing the reaction temperature. The results revealed that the formation of PPF-1 NS was attributed to the enlarged interlayer space and accelerated crystal growth rate along the lateral direction. PMID- 29177350 TI - Chalcogenide substitution in the [2Fe] cluster of [FeFe]-hydrogenases conserves high enzymatic activity. AB - [FeFe]-Hydrogenases efficiently catalyze the uptake and evolution of H2 due to the presence of an inorganic [6Fe-6S]-cofactor (H-cluster). This cofactor is comprised of a [4Fe-4S] cluster coupled to a unique [2Fe] cluster where the catalytic turnover of H2/H+ takes place. We herein report on the synthesis of a selenium substituted [2Fe] cluster [Fe2{MU(SeCH2)2NH}(CO)4(CN)2]2- (ADSe) and its successful in vitro integration into the native protein scaffold of [FeFe] hydrogenases HydA1 from Chlamydomonas reinhardtii and CpI from Clostridium pasteurianum yielding fully active enzymes (HydA1-ADSe and CpI-ADSe). FT-IR spectroscopy and X-ray structure analysis confirmed the presence of structurally intact ADSe at the active site. Electrochemical assays reveal that the selenium containing enzymes are more biased towards hydrogen production than their native counterparts. In contrast to previous chalcogenide exchange studies, the S to Se exchange herein is not based on a simple reconstitution approach using ionic cluster constituents but on the in vitro maturation with a pre-synthesized selenium-containing [2Fe] mimic. The combination of biological and chemical methods allowed for the creation of a novel [FeFe]-hydrogenase with a [2Fe2Se] active site which confers individual catalytic features. PMID- 29177351 TI - What factors determine the stability of a weak protein-protein interaction in a charged aqueous droplet? AB - Maintaining the interface of a weak transient protein complex transferred from bulk solution to the gaseous state via evaporating droplets is a critical question in the detection of the complex association (dissociation) constant by using electrospray ionization mass spectrometry (ESI-MS). Here we explore the factors that may affect the stability of a protein-protein interaction (PPI) using atomistic molecular dynamics (MD) modelling of a complex of ubiquitin (Ub) and the ubiquitin-associated domain (UbA) (RCSB PDB code ) and a non-covalent complex of diubiquitin (RCSB PDB code ) in aqueous droplets. A general method is presented to determine the protonation states of the complexes we investigate in particular, and that of a protein in general, under various pH conditions that an evaporating droplet acquires due to its change in size. We find that the combination of high temperature and high charge states of the protein complexes may destabilize the interface by creating new interfaces instead of a direct rupture of the initial stable interface. We provide evidence that highly charged protein complexes are found in droplets that form conical extrusions of the solvent on the surface due to charge-induced instability. This distinct droplet morphology leads to a higher solvent evaporation rate that assists in transferring the complex in the gaseous state without dissociation. The conical solvent protrusions expose on the droplet surface certain amino acids that otherwise would be solvated in a droplet with the protein complex of low charge states. The new vapor-protein interface does not have a direct effect on the stability of the PPI. A common way in experiments to stabilize the protein complexes in droplets is to reduce the protonation state of the proteins. Here we find that weakly bound protein complexes even at high protonation states can be stabilized by the presence of a small number of counterions, without affecting the protonation state of the protein. Our findings may provide guiding principles in ESI-MS experiments to stabilize weak transient PPIs. PMID- 29177352 TI - O2 activation at a trispyrazolylborato nickel(ii) malonato complex.

PMID- 29177353 TI - Switch-on fluorescent/FRET probes to study human histidine triad nucleotide binding protein 1 (hHint1), a novel target for opioid tolerance and neuropathic pain. AB - Histidine Triad Nucleotide Binding Protein 1 (Hint1) has emerged to be an important post-synaptic protein associated with a variety of central nervous system disorders such as pain, addiction, and schizophrenia. Recently, inhibition of histidine nucleotide binding protein 1 (Hint1) with a small nucleoside inhibitor has shown promise as a new therapeutic strategy for the treatment of neuropathic pain. Herein, we describe the first rationally designed small molecule switch-on probes with dual fluorescence and FRET properties to study Hint1. Two non-natural fluorescent nucleosides with a fluorescent lifetime of 20 and 25 ns were each coupled through a linker to the indole ring, i.e. probes 7 and 8. Both probes were found to be water soluble and quenched intramolecularly via photoinduced electron transfer (PET) resulting in minimal background fluorescence. Upon incubating with Hint1, compound 7 and 8 exhibited a 40- and 16 fold increase in the fluorescence intensity compared to the control. Compounds 7 and 8 bind Hint1 with a dissociation constant of 0.121 +/- 0.02 and 2.2 +/- 0.36 MUM, respectively. We demonstrate that probe 8 exhibits a switch-on FRET property with an active site tryptophan residue (W123). We show the utility of probes in performing quantitative ligand displacement studies, as well as in selective detection of Hint1 in the cell lysates. These probes should be useful for studying the dynamics of the active site, as well as for the development of fluorescence lifetime based high throughput screening assay to identify novel inhibitors for Hint1 in future. PMID- 29177354 TI - Functionalized graphene sheets for intracellular controlled release of therapeutic agents. AB - Since therapeutic agents target specific compartments inside the cells, their efficiency depends on their intracellular release from drug delivery systems (DDS). However, control over the intracellular release of therapeutic agents is a challenging issue and can only be achieved by governing their interactions with the DDS. In this work, polyglycerol amine- and polyglycerol sulfate functionalized graphene sheets as positively and negatively charged 2D nanomaterials with 150 nm lateral size were used to deliver and control the release of doxorubicin (DOX) inside cells. A pH-sensitive dye was conjugated onto the surfaces of graphene sheets and used as an antenna to obtain specific signals from the acidic cell compartments. It was found that both positively and negatively charged graphene sheets undergo similar acidification processes after cellular uptake. Nevertheless, the intracellular drug release of these DOX-loaded nanomaterials was distinctly different. As an overall effect of the pi-pi stacking and electrostatic interactions, the release of DOX from the positively charged graphene sheets was much faster than that from their analogs with a negative surface charge. Therefore, therapeutic efficiency in the first case was much higher than that in the latter. Based on our findings, the intracellular release of drugs from the surfaces of graphene sheets can be finely tuned by manipulating their functionalities, which is of great importance in the designing of the future graphene-based nanomedicines. PMID- 29177355 TI - Nanoparticles grown from methanesulfonic acid and methylamine: microscopic structures and formation mechanism. AB - Mechanisms of particle formation and growth in the atmosphere are of great interest due to their impacts on climate, health and visibility. However, the microscopic structures and related properties of the smallest nanoparticles are not known. In this paper we pursue computationally a microscopic description for the formation and growth of methanesulfonic acid (MSA) and methylamine (MA) particles under dry conditions. Energetic and dynamics simulations were used to assess the stabilities of proposed model structures for these particles. Density functional theory (DFT) and semi-empirical (PM3) calculations suggest that (MSA MA)4 is a major intermediate in the growth process, with the dissociation energies, enthalpies and free energies indicating considerable stability for this cluster. Dynamics simulations show that this species is stable for at least 100 ps at temperatures up to 500 K, well above atmospheric temperatures. In order to reach experimentally detectable sizes (>1.4 nm), continuing growth is suggested to occur via clustering of (MSA-MA)4. The dimer (MSA-MA)4(MSA-MA)4 may be one of the smaller experimentally measured particles. Step by step addition of MSA to (MSA-MA)4, is also a likely potential growth mechanism when MSA is excess. In addition, an MSA-MA crystal is predicted to exist. These studies demonstrate that computations of particle structure and dynamics in the nano-size range can be useful for molecular level understanding of processes that grow clusters into detectable particles.

In this study, we design a gradient electrospinning method for the controllable synthesis of Mn Fe/CeO2 nanocatalysts and their application in the combustion of propane and methane. The strategy is rational, and the nanostructure of Mn-Fe/CeO2 can be tuned by simply adjusting the weight ratio of polyvinyl pyrrolidone (PVP)/polyacrylonitrile (PAN) during the electrospinning process. Benefitting from its unique structural feature, propane and methane conversions in hollow tubular Mn-Fe/CeO2-P1 (mPVP : mPAN = 1 : 1) are more than 90% at 382 and 411 degrees C, respectively. The superior propane oxidation performance in Mn-Fe/CeO2 P1 is associated with its hollow tubular structure, high surface oxygen vacancies and excellent low-temperature reducibility.

AB - Assemblies of gold nanoparticles with chain-like morphologies and new near infrared (NIR) localized surface plasmon resonance (LSPR) are obtained by adding the biotin-binding proteins avidin, neutravidin or streptavidin to citrate-capped nanoparticles. The key idea behind this one-step fabrication method is to destabilize the colloids by adding positively charged proteins and/or by making their zeta potential less negative. The extent of assembly, and therefore the NIR LSPR, can be fine-tuned by varying the concentration of proteins as well as by changing the pH of the solution. The resulting nanoparticle clusters can also reconfigure into smaller assemblies that absorb less NIR light by adding thiolated molecules or by increasing the pH of the solution. This, along with the observation that the proteins retain their biotin-binding properties in the assemblies, makes the proposed method promising for the development of new biosensors and drug delivery platforms capable of self-regulating their optical properties as a function of chemical signals in their environment.

AB - The approach of molecular dynamics with Reactive Force Field (ReaxFF) is a promising way to investigate the carburization of iron which is pivotal in the preparation of desired iron-based materials and catalysts. However, it is a challenge to develop a reliable ReaxFF to describe the Fe-C interaction, especially when it involves bond rearrangement. In this work, we develop an exclusive set of Reactive Force Field (ReaxFF) parameters, denoted RPOIC-2017, to describe the diffusion behavior of carbon atoms in the alpha-Fe system. It inherited some partial parameters in 2012 (ReaxFF-2012) which are suitable for hydrogen adsorption and dissociation. This set of parameters is trained against data from first-principles calculations, including the equations of state of alpha-Fe, the crystal constant of Fe3C and Fe4C, a variety of periodic surface structures with varying carbon coverages, as well as the barriers of carbon diffusion in the alpha-Fe bulk and on diverse surfaces. The success in predicting the carbon diffusion coefficient and the diffusion barrier using the developed RPOIC-2017 potential demonstrates that the performance is superior to that of the traditional MEAM potential. The new ReaxFF for the Fe-C interaction developed in this work is not only essential for the design of novel iron based materials, but could also help understand atomic arrangements and the interfacial structure of iron carbides.

AB - Metal nanoclusters (NCs) have attracted broad attention for their molecular-like electronic structures and unique emission properties, but the difficulty in controlling emission color greatly limits their application in illumination and display. In this work, we demonstrate the capability to control the self-assembly induced emission (SAIE) of Cu NCs by modulating the inter-NC distance in the self assembly materials, which is capable of tuning the emission color from green to red. The inter-NC distance is mainly modulated by controlling the experimental variables during the NC self-assembly, such as the species of the solvents and ligands, duration of assembly, temperature, and so forth. These experimental variables influence the balance of inter-NC weak interactions, thus altering the distance of as-assembled NCs. The variation of the inter-NC distance greatly influences the photo-physical behavior of Cu NCs, and in particular the ligand-to Cu-Cu charge transfer, permitting the tuning of the emission color. As the Cu NCs self-assembly materials exhibit strong, stable, and color-tunable SAIE, they are employed as the color conversion materials for fabricating white light-emitting diodes.

AB - Depositing Pt atoms on nanoscale two-dimensional (2D) substrates resulting in the exposure of specific crystal facets is an effective strategy for reducing the Pt content without compromising the catalytic property. Herein, the Pd/PtCu core/shell nanoplates exhibit substantially improved ORR and MOR mass activities, 8.3 and 3.3 times higher than those of commercial Pt. The present work highlights the important role of designing a 2D core/shell nanostructure in enhancing fuel cell electrocatalysis. PMID- 29177361 TI - Synthetic strategies, diverse structures and tuneable properties of polyoxo titanium clusters. AB - As one of the most prosperous classes of cluster-based materials reported to date, polyoxo-titanium clusters (PTCs) have been closely related to many photo activities that broadly impact not only chemical but also energy and environmental sciences. In contrast to the well-developed polyoxometalates like polyoxotungstates and polyoxomolybdates, there is still large room for the development of PTCs. The exploration of crystalline PTC materials originates from the molecular model of technically important TiO2 materials but has been greatly hindered by their daunting and challenging synthesis. This review firstly summarizes the conventional and latest successful synthetic strategies applied to improve the poor degree of control of crystallization of PTCs. And attributed to the synthetic progress achieved in this area, there is a growing number of PTCs with diverse structures known to us, also enabling us to study their bandgap engineering and light absorption behaviours at the molecular level. In addition, exploitation of their applications in many fields is also under way. PMID- 29177362 TI - Improved efficient perovskite solar cells based on Ta-doped TiO2 nanorod arrays. AB - Organometal halide perovskite solar cells (PSCs) are nowadays regarded as a rising star in photovoltaics. In particular, PSCs incorporating oriented TiO2 nanorod (NR) arrays as the electron transport layer (ETL) have attracted significant attention owing to TiO2 NR's superior electron transport abilities and its potential in long-term stable PSCs. In addition to improve the electron transport ability of TiO2 NRs, the tuning of the band alignments between the TiO2 NR array and the perovskite layer is also crucial for achieving efficient solar cells. This work describes a facile, one-step, solvothermal method for the preparation of tantalum (Ta) doped TiO2 NR arrays for efficient PSCs. It is shown that the trace doping with Ta tunes the electronic structure of TiO2 NRs by a synergistic effect involving the lower 5d orbitals of the doped Ta5+ ions and the reduced oxygen vacancies. The synergistic tuning of the electronic structure improves the band alignment at the TiO2 NR/perovskite interface and boosts the short-circuit current and the fill factor. By using the optimized doped TiO2 NR array as the ETL, a record efficiency of 19.11% was achieved, which is the highest among one-dimensional-array based PSCs. PMID- 29177363 TI - Self-assembled selenium nanoparticles and their application in the rapid diagnostic detection of small cell lung cancer biomarkers. AB - By coupling molecular imprinting, chitosan biosorption and TiO2 photocatalysis, selenium nanoparticles (Se NPs) were self-assembled in a controlled manner on the molecular imprinting sites of zeolite-chitosan-TiO2 microspheres. Se NPs with different sizes and areal densities were individually synthesized by controlling the rapid adsorption of molecular-imprinted nanocomposites and photocatalytic reaction of TiO2 nanoparticles. In order to improve the sensitivity and specificity of rapid diagnostic detection, Se NPs were self-assembled again into high-order and spherically stable structures with an average size of 80 nm by well-defined monomer units, after separation from zeolite-chitosan-TiO2 microspheres with a stabilizer of 0.3% (v/v) bovine serum albumin. Due to their biological activity, spherical-shaped Se NPs were used for dot-blot immunoassays with multiple native antigens for rapid serodiagnosis of human lung cancer. The sensitivity of the dot immunoassays for detecting progastrin-releasing peptide (ProGRP) was 75 pg mL-1. The detection time of colloidal Se dot immunoassays for ProGRP was only 5 min. No positive results were observed with other commonly potential interfering substances, including carcinoembryonic antigen, alpha fetoprotein antigen and BSA. The research presents a simple and green method for the reuse of SeO32- and the controlled synthesis of Se NPs for biological and medical applications by bioaffinity adsorption and photoreduction.

AB - INTRODUCTION: With the global outbreak of Zika virus and its association with microcephaly, an up-to-date fetal head circumference (HC) nomogram is crucial to offer a reference standard in order to make an accurate diagnosis. This study was conducted to revise the local fetal HC nomogram. MATERIALS AND METHODS: In this retrospective study, ultrasound data was used for construction of the fetal HC nomogram from a total of 6155 pregnancies in the ethnic Chinese population with low risk profile at KK Women's and Children's Hospital over a 10-year period. Regression model was fitted to calculate the mean and standard deviation of HC at each gestational age (GA). Comparison of HC between ethnic groups (no significant differences) and genders were made. The revised chart was compared with another commonly used reference chart (Hadlock). In an independent test population, different reference charts were used to estimate number of cases with microcephaly. RESULTS: A statistically significant difference of HC between the genders was observed across all gestational ages. Gender-specific reference charts and equation were computed. Our revised fetal HC chart showed a different distribution from the Hadlock chart. Compared with the gender-specific charts, the Hadlock HC chart would significantly under-report microcephaly cases in male fetuses, and tend to over-report in female fetuses. CONCLUSION: This study provides a new set of gender-specific fetal HC charts in the Singaporean population for antenatal ultrasound surveillance of microcephaly. PMID- 29177366 TI - Glycaemic, Blood Pressure and Low Density Lipoprotein Cholesterol Control in Adult Patients with Diabetes in Singapore: A Review of Singapore Literature Over Two Decades. AB - INTRODUCTION: Diabetes mellitus is a burgeoning global health epidemic, with an estimated 422 million people living with diabetes in 2014. The number of adult diabetic patients in Singapore is expected to rise to 1 million in 2050. Despite advances made in the management of diabetes and improvements in healthcare accessibility and delivery, the rate and complications of diabetes (myocardial infarction, stroke, kidney failure and lower limb amputation) in Singapore have not decreased. Gaps between guidelines and practice have been reported in several parts of the world. In this narrative review, we aimed to describe the control of diabetes in Singapore over the past 20 years. MATERIALS AND METHODS: We reviewed studies describing, or trials intervening in, the glycaemic, blood pressure (BP) and low density lipoprotein cholesterol (LDL-C) control of adult diabetic patients in Singapore published over the past 20 years (1997-2016). Studies selected from comprehensive electronic databases searches were reviewed by 4 reviewers (2 primary care physicians, 1 diabetologist and 1 public health epidemiologist). The GRADE approach was used to evaluate the quality of evidence. RESULTS: We included 23 articles involving 257,097 subjects. There were 9 longitudinal, 12 cross-sectional and 2 case-control studies. All studies reported mean/median HbA1c between 7.2%-8.6%. BP ranged between 126.5-144 mmHg (systolic) and 70-84 mmHg (diastolic) in 9 studies. Nine studies reported LDL-C between 2.4 3.3 mmol/L. CONCLUSION: Mirroring global patterns, the glycaemic, BP and LDL-C control in adult diabetic patients in Singapore do not appear to be treated to target in the majority of patients.

AB - OBJECTIVES: To investigate the perceptions of primary health workers (PHW) about the challenges of health care for migrants. MATERIALS AND METHODS: A qualitative multicase study was conducted in eight communes of Chile, using the snowball technique, where 101 PHW and local authorities were recruited. Semi-structured interviews and focal groups were conducted, achieving information saturation. RESULTS: The findings were grouped into two major thematic axes: 1. Technical and administrative difficulties, and 2. Perception of cultural barriers. According to the PHW, although regulations have been established and health care strategies have been generated for the migrant population, these are mostly not stable or known to all PHW. They are also not easy to implement in the various realities investigated. The absence of records on the number of migrants accessing the health system makes it difficult to design specific interventions. Additionally, health care has complications, and the PHW do not necessarily have tools that allow them to provide a care that is culturally sensitive to the needs of the migrant community. CONCLUSIONS: The findings put into question the new challenges in health that Chile is facing in the face of the growing migrant population. The needs perceived by PHW are: stability and clarity in the regulations in force in relation to access and provision of services, training in regulations and the concrete way in which they should operate, and sensitization in cultural competence.

AB - OBJECTIVES.: To investigate the effects of D-002, a mixture of 6 high molecular weight primary aliphatic alcohols, obtained from beeswax (Apis mellifera), on severe inflammatory ulcerative colitis (UC) induced by Dextran sulfate (DSS) and ethanol in rats (Ratus ratus). MATERIALS AND METHODS.: Rats were randomly distributed in six groups: a zero control to which no damage was caused, and five to which the UC was induced: a negative control (vehicle), three treated with D 002 (25, 100 and 400 mg/kg) and a positive control with sulfasalazine (200 mg/kg) (reference substance). Clinical manifestations (body weight variation, diarrhea and rectal bleeding), macroscopic and histological damage score, and myeloperoxidase (MPO) activity were quantified. RESULTS.: The oral treatment with D-002 (25, 100 and 400 mg/ kg) significantly prevented the decrease in body weight. The dose of 400 mg/kg reduced the presence of diarrhea and rectal bleeding, although its comparison with the negative control only reached statistical significance on diarrhea. D-002 (25, 100 and 400 mg/kg) significantly reduced the score of macroscopic lesions (40.0; 43.3 and 47.2% inhibition, respectively), the histological damage score (31.5; 53.7 and 67.1% inhibition, respectively) and the activity of MPO (73.2; 83.6 and 85.0% inhibition, respectively), compared to the negative control group. Sulfasalazine significantly reduced all variables studied. CONCLUSIONS.: D-002 (25, 100 and 400 mg/kg) significantly protected the colonic mucosa in rats with severe inflammatory UC induced by DSS and ethanol.

AB - OBJECTIVES: To evaluate the relationship between having a medical specialty and the monthly income of Peruvian doctors, and to compare the economic incomes among areas with higher and lower density of medical doctors in Peru. MATERIALS AND METHODS: : We analyzed data of the National Satisfaction Survey of Health Users (in Spanish: ENSUSALUD) carried out in Peru in the year 2015. This survey, with a national level of inference, was performed on physicians working at health facilities in Peru. Monthly income was measured considering all paid activities of the physician. Crude and adjusted prevalence ratios (PR and aPR) and their 95% confidence intervals (95% CI) were calculated through Poisson regression models with robust variance, taking into account the complex sampling of the survey. RESULTS: Out of 2 219 Physicians surveyed, 2 154 (97.0%) observations were analyzed. The probability of earning > S/5 000 (1 572.3 USD) per month was 29.1% for general practitioners; 65.6% for specialists; 63.0% for clinical specialists; 70.5% for surgeons, and 55.7% for other specialties. Compared to general practitioners, physicians with clinical, surgical, and other specialties were more likely to earn > S/5 000 per month (aPR = 1.44, 1.49, and 1.26, respectively). The probability of earning > S/5 000 was higher in those working in departments with low medical density. CONCLUSIONS: Monthly incomes were higher for specialist physicians than for non-specialists. Economic incomes were higher in departments with lower density of physicians, which may encourage physicians to work in these departments.

PMID- 29177378 TI - [Progression of chronic renal disease in a reference hospital of social security of Peru 2012-2015]. AB - OBJECTIVES.: To describe the characteristics of the population with chronic kidney disease (CKD) stage 3 and 4, to determine the factors associated with CKD progression and admission to renal replacement therapy (RRT), as well as renal survival. MATERIALS AND METHODS.: Longitudinal retrospective study of patients referred between January 2012 and December 2015 to the Renal Health Unit of the Hospital Nacional Edgardo Rebagliati Martins (HNERM), who were evaluated and followed by a multidisciplinary team. The clinical and laboratory data for each query were recorded in a software created specifically for the program. A multivariate logistic regression analysis was performed to assess the factors associated with the progression of CKD, a Cox regression model to predict the risk of entering RRT and the Kaplan-Meier method for renal survival analysis. RESULTS.: We assessed 1248 patients in stage 3A: 248 (20%), stage 3B: 548 (44%) and stage 4: 452 (36%). 352 (28%) progressed, being proteinuria the most important progression factor (OR: 3.2; CI 95%: 2,2-4.6). Proteinuria increases the risk of admission to RRT in four times and having a glomerular filtration rate < 30% in 3.6 times. Median follow-up was 12 months (RIC 5-27 months). 92 patients (7%) required to initiate RRT. Renal survival at 12 months of follow-up was 96% and at 24 months was 90%. CONCLUSIONS.: Our study shows that in a specialized center a significant proportion of patients with CKD does not progress in their disease and that the factor that is most associated with progression of disease and at the onset of RRT is proteinuria.

AB - OBJECTIVE: To determine the clinical and histological characteristics and prognostic factors of cervical cancer (CC) in young Peruvian patients. MATERIALS AND METHODS: Retrospective analysis of patients younger than 35 years old diagnosed with CC between 2008 and 2012 in the Instituto Nacional de Enfermedades Neoplasicas. RESULTS: 449 patients had epithelial neoplasms. The main histological types were: squamous cell carcinoma (84.9%), adenocarcinoma (11.0%) and adenosquamous carcinoma (2.4%). The average tumor size was 4.98 cm. Anemia (55.7%), elevated creatinine (21.2%) and hydronephrosis (13.8%) were also identified. 82.3% of the patients presented locally advanced disease. Stages IIB (47.4%) and IIIB (25.8%) were the most common. Overall 5-year survival was 59.5% (I, 90.9%; II, 57.5%; III, 42.7% and IV, 13.3%). Elevated creatinine, anemia, tumor size, parametrial involvement and hydronephrosis were factors that affected survival. No significant relation was found between histological type and survival. The presence of anemia (adjusted hazard ratio [aHR]: 2.5; 95% confidence interval [CI 95%]: 1.6-4.0) and hydronephrosis (aHR: 1.6; CI 95%: 1.0 4.0) were independently associated with survival; likewise, the parametrial commitment with (aHR: 3.3; CI 95%: 1.5-7.2) or without (aRH: 2.6; CI 95%: 1.3 5.3) extension to the pelvic bone. CONCLUSIONS: Cervical cancer in young Peruvians is diagnosed in advanced stages. Overall survival in each stage is similar to the reported in older patients. The importance of conventional prognosis- related factors was confirmed. Anemia was an important independent prognostic factor requiring further investigations.

AB - Aiming at describing the incidence, clinical characteristics and factors associated with neonatal meningitis (NM), a case series study was conducted from 2008 to 2015, where 53 neonates, 10 with early onset NM and 43 with late onset were included. An incidence of 1.5 per thousand live births and a lethality of 3.8% were found. The associated factors were peripartum fever, urinary tract infection and chorioamnionitis (P < 0.05). Frequent symptoms were fever (84.9%), hypotonia (77.4%) and hypoactivity (73.6%). In the cerebrospinal fluid (CSF), the cases of early NM presented a median of 330 leukocytes/ul and 29 mg/dl of glucose, and the cases of late NM presented 170 leukocytes/ul and 32 mg/dl of glucose. The most common bacteria were Listeria monocytogenes (16.9%) and negative coagulase staphylococcus (11.3%). In conclusion, the incidence was high compared to other studies and the associated factors were the expected.

AB - The objective of the study was to determine the psychometric properties of the Dundee Ready Education Environment Measure (DREEM) questionnaire in students of a Peruvian medical school. Participants were first-to-sixth-year students, invited to participate through a web platform. In the analysis the alpha coefficient of Cronbach was used to evaluate internal consistency. In addition, a confirmatory factorial analysis was performed to evaluate the construct validity of the subscales of the DREEM. The adjustment quality indexes used were: Root Mean Square Error Approximation (RMSEA), the Index of Benchmarking (CFI), Tucker-Lewis Index (TLI), and the Standardized Root Mean Residual (SRMR). The results showed that the social self-perception dimension had an alpha of Cronbach of less than 0.70. In addition, the quality indices did not support the five-dimensional structure of the DREEM. In conclusion, the DREEM questionnaire did not perform optimally in this Peruvian sample. PMID- 29177386 TI - [Klebsiella pneumoniae NEW DELHI METALO-LACTAMASE IN A PERUVIAN NATIONAL HOSPITAL].

A recent contact prevalence was found for Ehrlichia of 3.7% (CI 95%: 3.0-4.4) and for Rickettsia of 10.6% (CI 95%: 9.1-12.1), and past contact for Ehrlichia of 19.0% (CI 95%: 17.1-21.0) and for Rickettsia of 23.3% (CI 95%: 21.2-25.3). It is concluded that there is a higher prevalence for past contact or infection in the population studied, both for Rickettsia and Ehrlichia, which would indicate an endemic behavior to both infectious agents in the geographic areas mentioned.

AB - The article presents the diagnosis of the living conditions of male and female adolescents in the area of the valley of the Apurimac, Ene and Mantaro rivers (in Spanish: VRAEM), who are exposed to situations of risk and social and sexual vulnerability and sexual due to the high levels of coca-leaf production and the context of the illegal drug trade which create the illusion of rapid social ascent. From this, it is necessary to ask: what are the living conditions and risk situations of adolescents in the VRAEM? And, what are the alternatives for an improvement of their situation from access to education and health care programs? This risk situation is the result of unequal gender relations, sexual violence, school dropout, teen pregnancy, alcohol and drug use, as well as of the lack of opportunities as a result of the participation in coca economy and illegal drug trade among adolescents in the VRAEM. Finally, we present the results of the attention of professionals of the health centers to promote counseling on sexual and reproductive health and access to health services of the Adolescent Life Program Life, as an opportunity to link the contents of the education curriculum and the compliance targets of this sector, highlighting the need of an approach of multiculturalism and gender equality in the access to health and education of adolescents.

Mapping of the evolution of thought of Carlos Monge Medrano on the health-illness process of andean populations]. AB - The main objective of this study is to describe how the ideas of Carlos Monge respect to high altitude sickness developed and how these were being deployed in the framework of the discussions on the living conditions of indigenous populations in the period 1928-1963. I postulate that the form how the Monge's paradigm was proposed, the tensions produced by various alternative movements and the way these contradictions were resolved were central, both for the subsequent development of different scientific disciplines and for their different institutional expressions in Peru. In addition, this article describes the evolutionary trajectory of Monge's ideas about the adaptation of indigenous populations to high altitude and the discussions that emerged with other research groups around the consumption of coca leaf. It also presents an analysis of the limitations of the biomedical view regarding the health of the Andean populations, a view that was progressively influenced by the changing social and political scenario in the context of the Cold War.

AB - In this article, we narrate and analyze the historical configuration that a group of female workers and a collective of social organizations made about the Hospital San Juan de Dios (HSJD) and Instituto Materno Infantil (IMI) in Bogota, Colombia, within the neoliberal crisis in health. Our ethnographic research intersects the Latinamerican traditions of collaborative ethnography and historic anthropology. The research was conducted in two sites. In the first one, from 2005 until 2015, we had informal conversations and conducted workshops and semi structured interviews with IMI workers. The second site corresponds to our participation in the deliberations of the Mesa Juridica por el San Juan de Dios (2008-2009), which aimed to elevate a class action to defend the hospitals. We found that workers and social organizations made use of the colonial origin of the hospitals and their institutionalization as center of welfare policies in the country as a way to highlight their patrimonial, historical, educational and social importance. This historical construction critiques efforts that negate or transform the public character of the hospitals and helped them carry on different actions to denounce the neoliberal health care reform as the cause of the hospitals most important crisis and closing. The different actors denounce the change in the hospitals-state relationship, which transited from being central for the development of social policies to reflecting a symbolic and material elimination of the hospitals. Such transition benefits the market interests established by the neoliberal model. PMID- 29177391 TI - [Intercultural health: The life cycle stages in the Andes]. AB - The most relevant theories and ideas about the life cycle in the Andes and their relationship with human development and health are presented. The life cycle is not an immutable phenomenon, the number of stages and its meaning is historically and culturally based. A comparative analysis with the theory of Freud and Erikson was made. It is concluded that the contribution of Andean culture focuses on: 1) Each stage of human development is associated with productive and reproductive processes of life in relation, as well as an adequate balance between rights and duties in life in society; 2) The couple is the basic social unit, and not the individual. It is a contribution to the design of health interventions with an intercultural approach.

AB - Tuberculosis (TB) is the first cause of death by an infectious agent in the world, the incidence in the population is declining very slowly and drug resistance is currently considered an international crisis. In Peru, the recent TB Prevention and Control Act in Peru (Law 30287) declares the fight against TB of national interest. In recent years, the Ministry of Health's (MINSA) National Health Strategy for the Prevention and Control of Tuberculosis (ESNPCT) has achieved significant progress in the control of this disease; however, challenges still remain to be addressed. This article reviews the epidemiological situation of TB in Peru, systematizes the progress achieved during the management of the ESNPCT >team between the years 2011 and 2015 from the biomedical approach, public management and social determinants of health, also posing challenges to achieving TB control under law 30287 and the "End of TB" strategy of the World Health Organization (WHO).

AB - Currently, there is a Peruvian legal framework that promotes the dissemination of information on the health rights of the population. Institutions have been created, such as the National Superintendence of Health, which are in charge of promoting health rights and supervising health-care providers. Despite many achievements, such as extending comprehensive health insurance coverage, it is necessary to implement strategies for the population to access information and advice in a timely, quick and complete manner. Some experiences have shown potential for expansion and growth, such as citizens' participation in Health Service User Councils and the Program of Integrated Actions for the Promotion of Health Rights, as well as the formation of decentralized Intendencies of the National Superintendency of Health. The conciliation and arbitration centers, the training of community health agents, the citizen vigilance, and even innovative strategies using information and communication technologies such as free smartphone applications, are important mechanisms for citizens to have more information and knowledge in health, and thus, to be more empowered, having the capacity to exert more control over the decisions taken on their health.

AB - Several of the acute diseases with infectious etiology (viral, bacterial or parasitic) initially start with a syndrome which can be febrile, febrile icteric, febrile hemorrhagic, febrile with respiratory manifestations, febrile with neurological impairment, febrile with dermal eruptions, febrile anemic, diarrheal, necrotic cutaneous ulcer, or deaths of febrile patients may occur without a defined diagnosis, with some variants according to the ecological social niche in which they occur; the syndromic approach is important, to quickly classify the case or the outbreak and thus have an appropriate and timely diagnosis that allows to orient both the individual management and the prevention and control measures in the population, even if there are limitations for the diagnosis of all the cases. This article describes the syndromic approach, the syndromes of importance in public health (collective) and their approach, all this is important because of its presentation in outbreaks that are occurring in the various ecological niches of our country, exacerbated by climate change.

AB - There is little information on the presence of the Mycobacterium avium Intracellulare (MAC) complex in Peru. Five cases of MAC infection are described in patients with HIV/AIDS at the National Hospital Dos de Mayo, Lima - Peru. The patients presented, mainly, persistent fever, chronic diarrhea, consumptive syndrome, pancytopenia and citofagocitosis. In all of them, resistant acid alcohol bacilli were identified in feces, so they received antituberculous treatment. The culture of feces was negative for Mycobacterium tuberculosis and, later, in all cases MAC was identified using a molecular test (genotype) in the culture of feces. Three patients received treatment for MAC right after identification; however, they all died. Before presentations similar to the reported, we suggest the use of higher performance methods (blood culture, myeloculture, molecular tests), as well as early associating drugs with activity for MAC to antitubercular scheme with the intention of improving the prognosis of this group of patients.

AB - Patients with HIV are susceptible to mycobacterium infection. In the case of fast growing mycobacteria, the group to which Mycobacterium fortuitum (M. fortuitum) belongs, infections have been described in the skin, lungs, lymph nodes and disseminated disease. We present the case of a 43-year-old male patient with pre diagnosis of HIV in antiretroviral therapy, which comes as a fever, asthenia, weight loss and chronic diarrhea. Abdominal tomography is performed and hepatosplenomegaly is evidenced with nodular lesions in the spleen. The splenic culture was finally positive for M. Fortuitum, with positive PCR to Mycobacterium tuberculosis. The current treatment protocols for this type of infection are based on the susceptibility shown in the cultures performed. With regard to coinfections between M. Fortuitum and Mycobacterium tuberculosis, in HIV positive patients, there are even less information.

AB - Background: In addition to protecting against measles, measles vaccine (MV) may have beneficial nonspecific effects. We tested the effect of an additional early MV on mortality and measles antibody levels. Methods: Children aged 4-7 months at rural health and demographic surveillance sites in Burkina Faso and Guinea-Bissau were randomized 1:1 to an extra early standard dose of MV (Edmonston-Zagreb strain) or no extra MV 4 weeks after the third diphtheria-tetanus-pertussis hepatitis B-Haemophilus influenzae type b vaccine. All children received routine MV at 9 months. We assessed mortality through home visits and compared mortality from enrollment to age 3 years using Cox proportional hazards models, censoring for subsequent nontrial MV. Subgroups of participants had blood sampled to assess measles antibody levels. Results: Among 8309 children enrolled from 18 July 2012 to 3 December 2015, we registered 145 deaths (mortality rate: 16/1000 person years). The mortality was lower than anticipated and did not differ by randomization group (hazard ratio, 1.05; 95% confidence interval, 0.75-1.46). At enrollment, 4% (16/447) of children in Burkina Faso and 21% (90/422) in Guinea Bissau had protective measles antibody levels. By age 9 months, no measles unvaccinated/-unexposed child had protective levels, while 92% (306/333) of early MV recipients had protective levels. At final follow-up, 98% (186/189) in the early MV group and 97% (196/202) in the control group had protective levels. Conclusions: Early MV did not reduce all-cause mortality. Most children were susceptible to measles infection at age 4-7 months and responded with high antibody levels to early MV. Clinical Trials Registration: NCT01644721. PMID- 29177408 TI - Organizing and implementing a multidisciplinary fast track oncology clinic. AB - Quality problem: Patients with gastrointestinal malignancies often need multiple appointments with different medical specialists, causing waiting times to accrue. Initial assessment: In our hospital, care is organized in a sequential manner, causing long waiting times. To reduce this, a fast track outpatient clinic (FTC) was implemented. Choice of solution: The FTC was organized within the hospital's existing structure. Patient centered care was achieved by ensuring that the medical specialists visit the patient, implementing nurse coordinators and considering patient wishes and co-morbidities when formulating a treatment plan. Implementation: A mandate from the board (Top-down), ensured cooperation between different medical departments and a change in resource allocation (i.e. medical staff); a horizontal clinic across a vertical departmental structure. Brainstorm sessions between the departments led by two physicians who were going to work at the FTC (Bottom-up), assured a swift implementation of the FTC. Evaluation: Since implementation in 2009, patient influx has tripled. Waiting time for an appointment and start of treatment was reduced from 2-4 weeks to 6 working days and from 12-14 weeks to 17 working days, respectively. This was achieved by re allocating recourses, but without increasing existing resources. Lessons learned: The combination of a top-down and bottom-up strategy ensured participation from all involved departments, a strong foundation and a shared vision on patient centered care. The FTC facilitates sharing information between different medical specialists through both proximity and a shared electronic patient record. The implementation of the FTC comprises a change in organization, but not a change in structure. PMID- 29177409 TI - Barriers and facilitators related to the implementation of a physiological track and trigger system: A systematic review of the qualitative evidence. AB - Purpose: To identify the barriers to, and facilitators of, the implementation of physiological track and trigger systems (PTTSs), perceived by healthcare workers, through a systematic review of the extant qualitative literature. Data sources: Searches were performed in PUBMED, CINAHL, PsycInfo, Embase and Web of Science. The reference lists of included studies were also screened. Study selection: The electronic searches yielded 2727 papers. After removing duplicates, and further screening, a total of 10 papers were determined to meet the inclusion criteria and were reviewed. Data extraction: A deductive content analysis approach was taken to organizing and analysing the data. A framework consisting of two overarching dimensions ('User-related changes required to implement PTTSs effectively' and 'Factors that affect user-related changes'), 5 themes (staff perceptions of PTTSs and patient safety, workflow adjustment, PTTS, implementation process and local context) and 14 sub themes was used to classify the barriers and facilitators to the implementation of PTTSs. Results of data synthesis: Successful implementation of a PTTS must address the social context in which it is to be implemented by ensuring that the users believe that the system is effective and benefits patient care. The users must feel invested in the PTTS and its use must be supported by training to ensure that all healthcare workers, senior and junior, understand their role in using the system. Conclusion: PTTSs can improve patient safety and quality of care. However, there is a need for a robust implementation strategy or the benefits of PTTSs will not be realized. PMID- 29177411 TI - Ultrasmall Superparamagnetic Iron Oxide Imaging Identifies Tissue and Nerve Inflammation in Pain Conditions. AB - Objective: Correlation between radiologic structural abnormalities and clinical symptoms in low back pain patients is poor. There is an unmet clinical need to image inflammation in pain conditions to aid diagnosis and guide treatment. Ferumoxytol, an ultrasmall superparamagnetic iron oxide (USPIO) nanoparticle, is clinically used to treat iron deficiency anemia and showed promise in imaging tissue inflammation in human. We explored whether ferumoxytol can be used to identify tissue and nerve inflammation in pain conditions in animals and humans. Methods: Complete Freud's adjuvant (CFA) or saline was injected into mice hind paws to establish an inflammatory pain model. Ferumoxytol (20 mg/kg) was injected intravenously. Magnetic resonance imaging (MRI) was performed prior to injection and 72 hours postinjection. The changes in the transverse relaxation time (T2) before and after ferumoxytol injection were compared between mice that received CFA vs saline injection. In the human study, we administered ferumoxytol (4 mg/kg) to a human subject with clinical symptoms of lumbar radiculopathy and compared the patient with a healthy subject. Results: Mice that received CFA exhibited tissue inflammation and pain behaviors. The changes in T2 before and after ferumoxytol injection were significantly higher in mice that received CFA vs saline (20.8 +/- 3.6 vs 2.2 +/- 2.5, P = 0.005). In the human study, ferumoxytol-enhanced MRI identified the nerve root corresponding to the patient's symptoms, but the nerve root was not impinged by structural abnormalities, suggesting the potential superiority of this approach over conventional structural imaging techniques. Conclusions: Ferumoxytol-enhanced MRI can identify tissue and nerve inflammation and may provide a promising diagnostic tool in assessing pain conditions in humans. PMID- 29177410 TI - Relationship of acid-base status with arterial stiffness in community-living elders: the Health ABC Study. AB - Background: Animal studies suggest that acidosis protects against arterial calcification, which contributes to arterial stiffness. The goal of this study was to investigate the associations of serum bicarbonate and pH with arterial stiffness in community-living older adults. Methods: We performed cross-sectional analyses among 1698 well-functioning participants 70-79 years of age. Bicarbonate and pH were measured by arterialized venous blood gas at the point of care. Bicarbonate was categorized into low (<23 mEq/L), normal (23-27.9) and high (>=28). Arterialized venous pH (AVpH) was categorized into tertiles: <=7.40, >7.40-7.42 and >7.42. Arterial stiffness was evaluated by pulse wave velocity (PWV) and high ankle-brachial index (ABI; >1.3/incompressible). We used linear and logistic regression to evaluate the association of bicarbonate and AVpH with PWV and high ABI, respectively. Results: The mean age was 76 years and 15% had an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m 2 . The mean bicarbonate was 25.2 +/- 2.1 mEq/L and the mean AVpH was 7.41 +/- 0.03. Compared with participants in the normal bicarbonate category, those in the low bicarbonate group had 8.8% higher PWV (P = 0.006) and 1.87 greater odds of high ABI (P = 0.04). However, the associations were not significant after adjusting for eGFR (P = 0.24 and 0.43, respectively). There was no difference in PWV or high ABI across AVpH tertiles. Results were similar in those with and without chronic kidney disease and after excluding participants on diuretics. Conclusions: We did not observe an independent association of bicarbonate or AVpH with arterial stiffness measured by high PWV or ABI in community-living older individuals. Future studies evaluating patients with a greater severity of chronic kidney disease and with more extreme alterations in acid-base status are warranted. PMID- 29177412 TI - Prefrontal Recruitment Mitigates Risk-Taking Behavior in Human Immunodeficiency Virus-Infected Young Adults. AB - Background: Human immunodeficiency virus (HIV)-infected (HIV+) young adults often engage in risk-taking behavior. However, the disruptive effects of HIV on the neurobiological underpinnings of risky decision making are not well understood. Methods: Risky decision making, measured via the Iowa Gambling Task (IGT), was compared voxel-wise to resting cerebral blood flow (rCBF) acquired via arterial spin labeling. Separate topographical maps were obtained for HIV-uninfected (HIV ; n = 62) and HIV+ (n = 41) young adults (18-24 years old) and were compared to the full cohort of participants. For the HIV+ group, rCBF was compared to recent and nadir CD4. Results: IGT performance was supported by rCBF in 3 distinct brain regions: regions I, II, and III. The relationship between IGT performance and rCBF in HIV+ individuals was most robust in region I, the ventromedial prefrontal and insular cortices. Region II contained strong relationships for both HIV- and HIV+. Region III, dorsolateral prefrontal and posterior cingulate cortices, contained relationships that were strongest for HIV- controls. IGT performance was intact among HIV+ participants with higher rCBF in either region I or region III. By contrast, performance was worse among HIV+ individuals with lower rCBF in both regions I and III when compared to HIV- controls (P = .01). rCBF in region III was reduced in HIV+ compared with HIV- individuals (P = .04), and positively associated with nadir CD4 cell count (P = .02). Conclusions: Recruitment of executive systems (region III) mitigates risk-taking behavior in HIV+ and HIV- individuals. Recruitment of reward systems (region I) mitigates risk-taking behavior when region III is disrupted due to immunological compromise. Identifying individual recruitment patterns may aid anatomically directed therapeutics or psychosocial interventions.

AB - OBJECTIVES: Our goal was to evaluate whether endothlin-1 (ET-1) plays an important role in the Fontan circulation. METHODS: Thirteen patients with single ventricle physiology (Glenn circulation, n = 7; Fontan circulation, n = 6) were evaluated using lung histopathological and immunohistochemical studies and then compared with the normal autopsied controls without congenital heart disease (n = 13). We evaluated the medial thickness of the small pulmonary arteries. For 10 of these patients, quantitative real-time polymerase chain reaction analyses of ET 1, endothelin receptors Type A and Type B, endothelin-converting enzyme-1 and endothelial nitric oxide synthase were performed. RESULTS: The medial thickness of the small pulmonary arteries in patients with single-ventricle physiology was greater than that of those in the control group (P = 0.0341). Severe medial hypertrophy of the pulmonary arteries was observed in patients who had poor outcomes. Immunohistochemical studies revealed that the marked expression of ET-1 was observed in the endothelium and media of their pulmonary arteries. In these patients, the messenger RNA expression of ET-1 was also increased. Two patients showed high levels of expression of ETAR and ETBR, although these 2 cases maintain good Fontan circulation. CONCLUSIONS: Medial hypertrophy and the overexpression of ET-1 in the pulmonary arteries were observed in some patients in whom the Fontan circulation failed. Our data suggest that ET-1 may play an important role in maintaining the Fontan circulation.

AB - Background: Owing to the emergence of multiresistant Plasmodium falciparum parasites in Southeast Asia, along with the impressive decrease in the efficacy of the endoperoxide compound artemisinin and of artemisinin-based combination therapies, the development of novel antimalarial drugs or combinations is required. Although several antiplasmodial molecules, such as endoperoxide-based compounds, are in advanced research or development, we do not know whether resistance to artemisinin derivatives might impact the efficacy of these new compounds. Objectives: To address this issue, the antiplasmodial efficacy of trioxaquines, hybrid endoperoxide-based molecules, was explored, along with their ability to select in vitro resistant parasites under discontinuous and dose escalating drug pressure. Methods: The in vitro susceptibilities of artemisinin- and trioxaquine-resistant laboratory strains and recent Cambodian field isolates were evaluated by different phenotypic and genotypic assays. Results: Trioxaquines tested presented strong cross-resistance with artemisinin both in the artemisinin-resistant laboratory F32-ART5 line and in Cambodian field isolates. Trioxaquine drug pressure over 4 years led to the in vitro selection of the F32-DU line, which is resistant to trioxaquine and artemisinin, similar to the F32-ART lineage. F32-DU whole genome sequencing (WGS) revealed that resistance to trioxaquine was associated with the same non-synonymous mutation in the propeller domain of the K13 protein (M476I) that was found in the F32-ART lineage. Conclusions: These worrisome results indicate the risk of cross resistance between artemisinins and endoperoxide-based antiplasmodial drugs in the development of the K13 mutant parasites and question the usefulness of these molecules in the future therapeutic arsenal. PMID- 29177422 TI - The TFIIE-related Rpc82 subunit of RNA polymerase III interacts with the TFIIB related transcription factor Brf1 and the polymerase cleft for transcription initiation. AB - Rpc82 is a TFIIE-related subunit of the eukaryotic RNA polymerase III (pol III) complex. Rpc82 contains four winged-helix (WH) domains and a C-terminal coiled coil domain. Structural resolution of the pol III complex indicated that Rpc82 anchors on the clamp domain of the pol III cleft to interact with the duplex DNA downstream of the transcription bubble. However, whether Rpc82 interacts with a transcription factor is still not known. Here, we report that a structurally disordered insertion in the third WH domain of Rpc82 is important for cell growth and in vitro transcription activity. Site-specific photo-crosslinking analysis indicated that the WH3 insertion interacts with the TFIIB-related transcription factor Brf1 within the pre-initiation complex (PIC). Moreover, crosslinking and hydroxyl radical probing analyses revealed Rpc82 interactions with the upstream DNA and the protrusion and wall domains of the pol III cleft. Our genetic and biochemical analyses thus provide new molecular insights into the function of Rpc82 in pol III transcription.

AB - In yeast, as in other eukaryotes, calcium plays an essential role in signaling transduction to regulate different processes. Many pieces of evidence suggest that glucose-induced activation of plasma membrane H+-ATPase, essential for yeast physiology, is related to calcium signaling. Until now, no protein that could be regulated by calcium in this context has been identified. Lpx1p, a serine protease that is also involved in the glucose-induced activation of the plasma membrane H+-ATPase, could be a candidate to respond to intracellular calcium signaling involved in this process. In this work, by using different approaches, we obtained many pieces of evidence suggesting that the requirement of calcium signaling for activation of the plasma membrane H+-ATPase is due to its requirement for activation of Lpx1p. According to the current model, activation of Lpx1p would cause hydrolysis of an acetylated tubulin that maintains the plasma membrane H+-ATPase in an inactive state. Therefore, after its activation, Lpx1p would hydrolyze the acetylated tubulin making the plasma membrane H+-ATPase accessible for phosphorylation by at least one protein kinase. PMID- 29177423 TI - Salicylic Acid and Jasmonic Acid Pathways are Activated in Spatially Different Domains Around the Infection Site During Effector-Triggered Immunity in Arabidopsis thaliana. AB - The innate immune response is, in the first place, elicited at the site of infection. Thus, the host response can be different among the infected cells and the cells surrounding them. Effector-triggered immunity (ETI), a form of innate immunity in plants, is triggered by specific recognition between pathogen effectors and their corresponding plant cytosolic immune receptors, resulting in rapid localized cell death known as hypersensitive response (HR). HR cell death is usually limited to a few cells at the infection site, and is surrounded by a few layers of cells massively expressing defense genes such as Pathogenesis Related Gene 1 (PR1). This virtually concentric pattern of the cellular responses in ETI is proposed to be regulated by a concentration gradient of salicylic acid (SA), a phytohormone accumulated around the infection site. Recent studies demonstrated that jasmonic acid (JA), another phytohormone known to be mutually antagonistic to SA in many cases, is also accumulated in and required for ETI, suggesting that ETI is a unique case. However, the molecular basis for this uniqueness remained largely to be solved. Here, we found that, using intravital time-lapse imaging, the JA signaling pathway is activated in the cells surrounding the central SA-active cells around the infection sites in Arabidopsis thaliana. This distinct spatial organization explains how these two phythormone pathways in a mutually antagonistic relationship can be activated simultaneously during ETI. Our results re-emphasize that the spatial consideration is a key strategy to gain mechanistic insights into the apparently complex signaling cross talk in immunity. PMID- 29177425 TI - Value of Neonicotinoid Insecticide Seed Treatments in Mid-South Corn (Zea mays) Production Systems. AB - Neonicotinoid seed treatments are one of several effective control options used in corn, Zea mays L., production in the Mid-South for early season insect pests. An analysis was performed on 91 insecticide seed treatment trials from Arkansas, Louisiana, Mississippi, and Tennessee to determine the value of neonicotinoids in corn production systems. The analysis compared neonicotinoid insecticide treated seed plus a fungicide to seed only with the same fungicide. When analyzed by state, corn yields were significantly higher when neonicotinoid seed treatments were used compared to fungicide only treated seed in Louisiana and Mississippi. Corn seed treated with neonicotinoid seed treatments yielded 111, 1,093, 416, and 140 kg/ha, higher than fungicide only treatments for Arkansas, Louisiana, Mississippi, and Tennessee, respectively. Across all states, neonicotinoid seed treatments resulted in a 700 kg/ha advantage compared to fungicide only treated corn seed. Net returns for corn treated with neonicotinoid seed treatment were $1,446/ha compared with $1,390/ha for fungicide only treated corn seed across the Mid-South. Economic returns for neonicotinoid seed treated corn were significantly greater than fungicide-only-treated corn seed in 8 out of 14 yr. When analyzed by state, economic returns for neonicotinoid seed treatments were significantly greater than fungicide-only-treated seed in Louisiana. In some areas, dependent on year, neonicotinoid seed treatments provide significant yield and economic benefits in Mid-South corn. PMID- 29177426 TI - The Neutrons for Science Facility at SPIRAL-2. AB - The neutrons for science (NFS) facility is a component of SPIRAL-2, the new superconducting linear accelerator built at GANIL in Caen (France). The proton and deuteron beams delivered by the accelerator will allow producing intense neutron fields in the 100 keV-40 MeV energy range. Continuous and quasi-mono kinetic energy spectra, respectively, will be available at NFS, produced by the interaction of a deuteron beam on a thick Be converter and by the 7Li(p,n) reaction on thin converter. The pulsed neutron beam, with a flux up to two orders of magnitude higher than those of other existing time-of-flight facilities, will open new opportunities of experiments in fundamental research as well as in nuclear data measurements. In addition to the neutron beam, irradiation stations for neutron-, proton- and deuteron-induced reactions will be available for cross sections measurements and for the irradiation of electronic devices or biological cells. NFS, whose first experiment is foreseen in 2018, will be a very powerful tool for physics, fundamental research as well as applications like the transmutation of nuclear waste, design of future fission and fusion reactors, nuclear medicine or test and development of new detectors.

PMID- 29177429 TI - Identification of a basidiomycete-specific Vilse-like GTPase activating proteins (GAPs) and its roles in the production of virulence factors in Cryptococcus neoformans. AB - Cryptococcus neoformans is a basidiomycetous pathogenic yeast that causes fatal infections in both immunocompetent and immunocompromised patients. Regulation on the production of its virulence factors is not fully understood. Here we reported the characterization of a gene, named CVH1(CNA06260), encoding a Drosophila Vilse like RhoGAP homolog, which is hallmarked by three conserved functional domains: WW, MyTH4 and RhoGAP. Phylogenetic analysis suggests that CVH1 is highly conserved from protists to mammals and interestingly in basidiomycetes, but absent in plants or Ascomycota and other lower fungi. This phylogenetic distribution indicates an evolutionary link among these groups of organisms. Functional analyses demonstrated that CVH1 was involved in stress tolerance and virulence factor production. By disrupting CVH1, we created a second mutant cvh1Delta with the CRISPR-Cas9 editing tool. The mutant strain exhibited hypersensitivity to osmotic stress by 2 M sorbitol and NaCl, suggesting defects in the HOG signaling pathway and an interaction of Cvh1 with the HOG pathway. Hypersensitivity of cvh1Delta to 1% Congo red and 0.01% SDS suggests that the cell wall integrity was impaired in the mutant. And cvh1Delta hardly produced the pigment melanin and capsule. Our study for the first time demonstrates that the fungal Vilse-like RhoGAP CVH1 is an important regulator of multiple biological processes in C. neoformans, and provides novel insights into the regulatory circuit of stress resistance/cell wall integrity, and laccase and capsule synthesis in C. neoformans.

AB - Dementia with Lewy bodies is characterized by the accumulation of Lewy bodies and Lewy neurites in the CNS, both of which are composed mainly of aggregated alpha synuclein phosphorylated at Ser129. Although phosphorylated alpha-synuclein is believed to exert toxic effects at the synapse in dementia with Lewy bodies and other alpha-synucleinopathies, direct evidence for the precise synaptic localization has been difficult to achieve due to the lack of adequate optical microscopic resolution to study human synapses. In the present study we applied array tomography, a microscopy technique that combines ultrathin sectioning of tissue with immunofluorescence allowing precise identification of small structures, to quantitatively investigate the synaptic phosphorylated alpha synuclein pathology in dementia with Lewy bodies. We performed array tomography on human brain samples from five patients with dementia with Lewy bodies, five patients with Alzheimer's disease and five healthy control subjects to analyse the presence of phosphorylated alpha-synuclein immunoreactivity at the synapse and their relationship with synapse size. Main analyses were performed in blocks from cingulate cortex and confirmed in blocks from the striatum of cases with dementia with Lewy bodies. A total of 1 318 700 single pre- or postsynaptic terminals were analysed. We found that phosphorylated alpha-synuclein is present exclusively in dementia with Lewy bodies cases, where it can be identified in the form of Lewy bodies, Lewy neurites and small aggregates (<0.16 um3). Between 19% and 25% of phosphorylated alpha-synuclein deposits were found in presynaptic terminals mainly in the form of small aggregates. Synaptic terminals that co localized with small aggregates of phosphorylated alpha-synuclein were significantly larger than those that did not. Finally, a gradient of phosphorylated alpha-synuclein aggregation in synapses (pre > pre + post > postsynaptic) was observed. These results indicate that phosphorylated alpha synuclein is found at the presynaptic terminals of dementia with Lewy bodies cases mainly in the form of small phosphorylated alpha-synuclein aggregates that are associated with changes in synaptic morphology. Overall, our data support the notion that pathological phosphorylated alpha-synuclein may disrupt the structure and function of the synapse in dementia with Lewy bodies. PMID- 29177430 TI - Conformational heterogeneity and bubble dynamics in single bacterial transcription initiation complexes. AB - Transcription initiation is a major step in gene regulation for all organisms. In bacteria, the promoter DNA is first recognized by RNA polymerase (RNAP) to yield an initial closed complex. This complex subsequently undergoes conformational changes resulting in DNA strand separation to form a transcription bubble and an RNAP-promoter open complex; however, the series and sequence of conformational changes, and the factors that influence them are unclear. To address the conformational landscape and transitions in transcription initiation, we applied single-molecule Forster resonance energy transfer (smFRET) on immobilized Escherichia coli transcription open complexes. Our results revealed the existence of two stable states within RNAP-DNA complexes in which the promoter DNA appears to adopt closed and partially open conformations, and we observed large-scale transitions in which the transcription bubble fluctuated between open and closed states; these transitions, which occur roughly on the 0.1 s timescale, are distinct from the millisecond-timescale dynamics previously observed within diffusing open complexes. Mutational studies indicated that the sigma70 region 3.2 of the RNAP significantly affected the bubble dynamics. Our results have implications for many steps of transcription initiation, and support a bend-load open model for the sequence of transitions leading to bubble opening during open complex formation. PMID- 29177431 TI - Significance of preoperative butyrylcholinesterase level as an independent predictor of survival in patients with upper urinary tract urothelial carcinoma treated with nephroureterectomy. AB - Objectives: Butyrylcholinesterase (BChE) is an alpha-glycoprotein synthesized in the liver. Its serum levels are reportedly correlated with disease activity in patients with cancer. The aim of this study was to estimate the potential prognostic significance of preoperative serum BChE levels in patients with upper urinary tract urothelial carcinoma (UTUC) undergoing radical nephroureterectomy (RNU). Methods: Of the 220 patients with UTUC who underwent RNU between 1995 and 2016 at Hirosaki University Hospital, 149 patients with available laboratory data were included for analysis. Covariates included age, sex, preoperative laboratory data, clinical T and N grades, tumor grade, tumor location and preoperative chemotherapy. Univariate and multivariate analyses were performed to identify clinical factors associated with overall survival (OS) and disease-free survival (DFS). Univariate analysis was performed using the Kaplan-Meier and log-rank methods, and the multivariate analysis was performed using a Cox proportional hazard model. Results: The median BChE level was 276 U/l and the optimal cut-off point for the serum BChE level was determined to be 218 IU/ml. The 5-year OS and DFS rates were 81.0% and 73.7%, respectively. The 5-year OS and DFS rates were significantly greater in the BChE >= 218 than <218 U/l groups (86.6% vs. 53.7%, P < 0.001 and 76.4% vs. 58.3%, P = 0.049, respectively). In multivariate analysis, BChE levels were most significantly associated with OS, whereas BChE level and tumor grade were significantly associated with DFS. Conclusions: This study validated preoperative serum BChE levels as an independent prognostic factor for UTUC after RNU.

AB - We report data for all Australians aged 0-19 y who underwent publicly funded nuclear medicine studies between 1985 and 2005, inclusive. Radiation doses were estimated for individual patients for 95 different types of studies. There were 374 848 occasions of service for 277 511 patients with a collective effective dose of 1123 Sievert (Sv). Most services were either bone scans (45%) or renal scans (29%), with renal scans predominating at younger ages and bone scans at older ages. This pattern persisted despite a 4-fold increase in the annual number of procedures. Younger children were more likely to experience multiple scans, with the third quartile of scans per patient dropping from two to one with patient age. The median effective dose per patient ranged from 1.3 mSv (4-7 y old) to 2.8 mSv (13-16 y old). This large data set provides valuable information on nuclear medicine services for young Australians in the period 1985-2005.

PMID- 29177434 TI - A randomized, open-label study of the efficacy and safety of AZD4547 monotherapy versus paclitaxel for the treatment of advanced gastric adenocarcinoma with FGFR2 polysomy or gene amplification. AB - Background: Approximately 5%-10% of gastric cancers have a fibroblast growth factor receptor-2 (FGFR2) gene amplification. AZD4547 is a selective FGFR-1, 2, 3 tyrosine kinase inhibitor with potent preclinical activity in FGFR2 amplified gastric adenocarcinoma SNU16 and SGC083 xenograft models. The randomized phase II SHINE study (NCT01457846) investigated whether AZD4547 improves clinical outcome versus paclitaxel as second-line treatment in patients with advanced gastric adenocarcinoma displaying FGFR2 polysomy or gene amplification detected by fluorescence in situ hybridization. Patients and methods: Patients were randomized 3:2 (FGFR2 gene amplification) or 1:1 (FGFR2 polysomy) to AZD4547 or paclitaxel. Patients received AZD4547 80 mg twice daily, orally, on a 2 weeks on/1 week off schedule of a 21-day cycle or intravenous paclitaxel 80 mg/m2 administered weekly on days 1, 8, and 15 of a 28-day cycle. The primary end point was progression-free survival (PFS). Safety outcomes were assessed and an exploratory biomarker analysis was undertaken. Results: Of 71 patients randomized (AZD4547 n = 41, paclitaxel n = 30), 67 received study treatment (AZD4547 n = 40, paclitaxel n = 27). Among all randomized patients, median PFS was 1.8 months with AZD4547 and 3.5 months with paclitaxel (one-sided P = 0.9581); median follow-up duration for PFS was 1.77 and 2.12 months, respectively. The incidence of adverse events was similar in both treatment arms. Exploratory biomarker analyses revealed marked intratumor heterogeneity of FGFR2 amplification and poor concordance between amplification/polysomy and FGFR2 mRNA expression. Conclusions: AZD4547 did not significantly improve PFS versus paclitaxel in gastric cancer FGFR2 amplification/polysomy patients. Considerable intratumor heterogeneity for FGFR2 gene amplification and poor concordance between FGFR2 amplification/polysomy and FGFR2 expression indicates the need for alternative predictive biomarker testing. AZD4547 was generally well tolerated. PMID- 29177435 TI - De novo mutations implicate novel genes in systemic lupus erythematosus. AB - The omnigenic model of complex disease stipulates that the majority of the heritability will be explained by the effects of common variation on genes in the periphery of core disease pathways. Rare variant associations, expected to explain far less of the heritability, may be enriched in core disease genes and thus will be instrumental in the understanding of complex disease pathogenesis and their potential therapeutic targets. Here, using complementary whole-exome sequencing, high-density imputation, and in vitro cellular assays, we identify candidate core genes in the pathogenesis of systemic lupus erythematosus (SLE). Using extreme-phenotype sampling, we sequenced the exomes of 30 SLE parent affected-offspring trios and identified 14 genes with missense de novo mutations (DNM), none of which are within the >80 SLE susceptibility loci implicated through genome-wide association studies. In a follow-up cohort of 10, 995 individuals of matched European ancestry, we imputed genotype data to the density of the combined UK10K-1000 genomes Phase III reference panel across the 14 candidate genes. Gene-level analyses indicate three functional candidates: DNMT3A, PRKCD, and C1QTNF4. We identify a burden of rare variants across PRKCD associated with SLE risk (P = 0.0028), and across DNMT3A associated with two severe disease prognosis sub-phenotypes (P = 0.0005 and P = 0.0033). We further characterise the TNF-dependent functions of the third candidate gene C1QTNF4 on NF-kappaB activation and apoptosis, which are inhibited by the p.His198Gln DNM. Our results identify three novel genes in SLE susceptibility and support extreme phenotype sampling and DNM gene discovery to aid the search for core disease genes implicated through rare variation. PMID- 29177436 TI - Designer tRNAs for efficient incorporation of non-canonical amino acids by the pyrrolysine system in mammalian cells. AB - The pyrrolysyl-tRNA synthetase/tRNAPyl pair is the most versatile and widespread system for the incorporation of non-canonical amino acids (ncAAs) into proteins in mammalian cells. However, low yields of ncAA incorporation severely limit its applicability to relevant biological targets. Here, we generate two tRNAPyl variants that significantly boost the performance of the pyrrolysine system. Compared to the original tRNAPyl, the engineered tRNAs feature a canonical hinge between D- and T-loop, show higher intracellular concentrations and bear partially distinct post-transcriptional modifications. Using the new tRNAs, we demonstrate efficient ncAA incorporation into a G-protein coupled receptor (GPCR) and simultaneous ncAA incorporation at two GPCR sites. Moreover, by incorporating last-generation ncAAs for bioorthogonal chemistry, we achieve GPCR labeling with small organic fluorophores on the live cell and visualize stimulus-induced GPCR internalization. Such a robust system for incorporation of single or multiple ncAAs will facilitate the application of a wide pool of chemical tools for structural and functional studies of challenging biological targets in live mammalian cells. PMID- 29177437 TI - Immunogenicity and Protection From a Single Dose of Internationally Available Killed Oral Cholera Vaccine: A Systematic Review and Metaanalysis. AB - In addition to improved water supply and sanitation, the 2-dose killed oral cholera vaccine (OCV) is an important tool for the prevention and control of cholera. We aimed to document the immunogenicity and protection (efficacy and effectiveness) conferred by a single OCV dose against cholera. The metaanalysis showed that an estimated 73% and 77% of individuals seroconverted to the Ogawa and Inaba serotypes, respectively, after an OCV first dose. The estimates of single-dose vaccine protection from available studies are 87% at 2 months decreasing to 33% at 2 years. Current immunologic and clinical data suggest that protection conferred by a single dose of killed OCV may be sufficient to reduce short-term risk in outbreaks or other high-risk settings, which may be especially useful when vaccine supply is limited. However, until more data suggest otherwise, a second dose should be given as soon as circumstances allow to ensure robust protection. PMID- 29177438 TI - Evaluating quality indicators of tertiary care hospitals for trauma care in Japan. AB - Objective: This study examined the associations between trauma mortality and quality of care indicators currently used in Japan. Design: This is a retrospective two-level discrete-time survival analysis. Quality indicators were derived from the 2012-2013 annual hospital survey conducted by the Ministry of Health, Labour and Welfare. Trauma mortality data were derived from the Japan Trauma Data Bank for the period of April 2012 to March 2013. Setting: Tertiary care centers designated as emergency and critical care centers (ECCCs) in Japan. Participants: The analysis included 12 378 patients aged >=15 years with blunt trauma and an Injury Severity Score >=9, registered to the data bank from 91 ECCCs. Intervention: Quality of care indicators examined in the annual hospital survey. Main Outcome Measures: Deaths within 30 days. Results: Of the 12 378 patients, 660 (5%) died within 30 days. Higher indicator score was significantly associated with lower mortality risk (hazard ratio [HR] for the second, third and fourth quartiles vs. lowest quartile 0.61, 0.55 and 0.52, respectively). Factors significantly associated with lower mortality risk were, higher patient volume (HR for the highest vs. lowest quartile, 0.74), director's qualification as specialist (HR 0.57) or consultant (HR 0.58), review of patient arrival process (HR 0.68), triage functions (HR 0.69), availability of psychiatrists (HR 0.75) and operating room being ready 24-h (HR 0.81). Conclusions: The study identified certain indicators associated with trauma patient mortality. Further refinement of indicators is required to specifically identify what needs changing. PMID- 29177439 TI - Attitudes, Beliefs, Practices, and Concerns Among Clinicians Prescribing Opioids in a Large Academic Institution. AB - Objectives: Opioid treatment of chronic noncancer pain (CNCP) adds complexity and uncertainty to patient interactions. We sought to assess clinician attitudes, beliefs, practice styles, and concerns around opioid prescribing following the release of the US Centers for Disease Control and Prevention (CDC) guideline for prescribing opioids for chronic pain. Methods: E-mailed electronic survey to clinicians at a large academic medical institution. Results: A total of 961 clinicians responded to the survey (response rate = 40%), 720 of whom prescribed opioids and were not in training. Sixty-five percent were physicians, and 35% were nurse practitioners or physician assistants, with a mean age of 47 years (SD +/- 11.4 years). Eighty-two percent were reluctant to prescribe opioids for CNCP, and only 47% expressed confidence in their care for CNCP patients. Sixty-seven percent were aware of the CDC guideline, 55% were enrolled in the state Prescription Drug Monitoring Program (PDMP), and 2% always or frequently prescribed naloxone to patients on opioids. Guideline awareness was associated with increased confidence in caring for CNCP patients. Clinicians having knowledge of a patient overdose were 31% more likely to be enrolled in the PDMP (relative rate= 1.31, 95% confidence interval = 1.14-1.52, chi-square = 11.00, P <0.01). Clinicians who knew of a patient overdose event were also more likely to express concern about patient opioid dependence and addiction. Conclusions: Opportunities exist to increase awareness of the CDC guideline and to increase clinician confidence in opioid prescribing. Knowledge of an overdose event may influence clinician behavior and concerns about dependence and addiction. PMID- 29177440 TI - Patients' preferences for adjuvant sorafenib after resection of renal cell carcinoma in the SORCE trial: what makes it worthwhile? AB - Background: We sought to determine the survival benefits that patients judged sufficient to warrant adjuvant therapy with sorafenib for 1 year, or for 3 years after resection of renal cell carcinoma in the SORCE trial. Methods: SORCE participants from all sites in Australia and New Zealand, and selected sites in the UK, completed a validated preferences questionnaire at months 0, 3, 15, and 42 to elicit the minimum survival benefits they judged sufficient to warrant adjuvant sorafenib for 1 year (versus observation), or for 3 years (versus 1 year). The questionnaires used reference survival times of 5 and 15 years; and reference survival rates at 5 years of 65% and 85%. Results: The 233 participants had a median age of 57 years (range 29-78) and 71% were male. For 1 year of sorafenib versus no adjuvant therapy, the median benefits in survival times judged sufficient to warrant treatment were an extra 9 months beyond 5 years and an extra 1 year beyond 15 years; the median benefit in survival rates were an extra 4% beyond 65% and an extra 3% beyond 85% at 5 years. For 3 years of sorafenib versus 1 year of sorafenib, the median benefit in survival time judged sufficient to warrant extended treatment was an extra 1 year beyond both 5 and 15 years. Participants randomly allocated to treatment with sorafenib judged larger benefits necessary than those allocated to placebo. Participants' preferences were not associated with their baseline characteristics or the interval from randomisation. Conclusion: Most participants judged an extra year of survival necessary to warrant 1 year of adjuvant sorafenib worthwhile, and an additional year of survival to warrant extending the duration of sorafenib from 1 to 3 years. Patients' preferences are important in shared decision making. SORCE trial clinical trials number: NCT00492258. PMID- 29177441 TI - De novo mutations in Caudal Type Homeo Box transcription Factor 2 (CDX2) in patients with persistent cloaca. AB - The cloaca is an embryonic cavity that is divided into the urogenital sinus and rectum upon differentiation of the cloacal epithelium triggered by tissue specific transcription factors including CDX2. Defective differentiation leads to persistent cloaca in humans (PC), a phenotype recapitulated in Cdx2 mutant mice. PC is linked to hypo/hyper-vitaminosis A. Although no gene has ever been identified, there is a strong evidence for a genetic contribution to PC. We applied whole-exome sequencing and copy-number-variants analyses to 21 PC patients and their unaffected parents. The damaging p.Cys132* and p.Arg237His de novo CDX2 variants were identified in two patients. These variants altered the expression of CYP26A1, a direct CDX2 target encoding the major retinoic acid (RA) degrading enzyme. Other RA genes, including the RA-receptor alpha, were also mutated. Genes governing the development of cloaca-derived structures were recurrently mutated and over-represented in the basement-membrane components set (q-value < 1.65 * 10-6). Joint analysis of the patients' profile highlighted the extracellular matrix-receptor interaction pathway (MsigDBID: M7098, FDR: q-value < 7.16 * 10-9). This is the first evidence that PC is genetic, with genes involved in the RA metabolism at the lead. Given the CDX2 de novo variants and the role of RA, our observations could potentiate preventive measures. For the first time, a gene recapitulating PC in mouse models is found mutated in humans. PMID- 29177442 TI - Increased 27-hydroxycholesterol production during luteolysis may mediate the progressive decline in progesterone secretion. AB - STUDY QUESTION: Does 27-hydroxycholesterol (27OH) actively facilitate the progression of luteolysis? SUMMARY ANSWER: There is increased mRNA expression of the enzyme that produces 27OH during luteolysis in vivo in rhesus macaques and sheep, and 27OH reduces progesterone secretion from human luteinized granulosa cells. WHAT IS KNOWN ALREADY: There is an increase in mRNA expression of liver x receptor (LXR) and a decrease in sterol regulatory element binding protein 2 (SREBP2) target genes during spontaneous luteolysis in primates, which could result in reduced cholesterol availability for steroidogenesis. Concentrations of 27OH are also increased in primate corpora lutea (CL) during luteolysis, and 27OH is a dual LXR agonist and SREBP2 inhibitor. STUDY DESIGN SIZE, DURATION: This was an in vitro study using primary human luteinized granulosa cells in a control versus treatment(s) design. Analyses of CL from sheep undergoing induced or spontaneous luteolysis were also performed, along with database mining of microarray data from rhesus macaque CL. PARTICIPANTS/MATERIALS, SETTING, METHODS: Primary luteinizing granulosa cells were obtained from 37 women aged 24-44 who were undergoing oocyte donation or IVF for male factor or idiopathic infertility, and cells were further luteinized in vitro using human chorionic gonadotropin. Three approaches to test the effect of 27OH produced via CYP27A1 (cytochrome p450, family 27, subfamily A, polypeptide 1) on luteinized granulosa cells were used: (i) direct 27OH supplementation, (ii) induction of endogenous CYP27A1 activity via pharmacologic inhibition of steroidogenesis, and (iii) siRNA mediated knockdown to directly inhibit CYP27A1 as well as cholesterol transport into the mitochondria via the steroidogenic acute regulatory protein (STAR). Endpoints included: progesterone (P4) secretion into culture media determined by enzyme immunoassay, cholesterol efflux and uptake assays using fluorescent lipid analogs, and mRNA expression determined via semi-quantitative real-time PCR (QPCR). An additional experiment involved QPCR analysis of 40 CL collected from ewes undergoing induced or spontaneous luteolysis, as well as database mining of microarray data generated from 16 rhesus macaque CL collected during spontaneous luteolysis and 13 macaque CL collected during a luteinizing hormone ablation and replacement protocol. MAIN RESULTS AND THE ROLE OF CHANCE: The mRNA expression of CYP27A1 was significantly increased during luteolysis in rhesus macaques and sheep in vivo, and CYP27A1 transcription was suppressed by luteinizing hormone and hCG. There was a significant decrease in hCG-stimulated P4 secretion from human luteinized granulosa cells caused by 27OH treatment, and a significant increase in basal and hCG-stimulated P4 synthesis when endogenous 27OH production was inhibited via CYP27A1 knockdown, indicating that 27OH inhibits steroidogenesis. Pharmacologic inhibition of steroidogenesis by aminoglutethimide significantly induced LXR and inhibited SREBP2 target gene mRNA expression, indicating that increased oxysterol production occurs when steroidogenesis is suppressed. Inhibiting cholesterol delivery into the mitochondria via knockdown of STAR resulted in reduced SREBP2 target gene mRNA expression, indicating that STAR function is necessary to maintain SREBP2-mediated transcription. The effects of 27OH treatment on markers of LXR and SREBP2 activity were moderate, and knockdown of CYP27A1 did not prevent aminoglutethimide-induced changes in LXR and SREBP2 target gene mRNA expression. These observations indicate that 27OH inhibits P4 secretion partially via mechanisms separate from its role as an LXR agonist and SREBP2 inhibitor, and also demonstrate that other oxysterols are involved in modulating LXR and SREBP2-mediated transcription when steroidogenesis is suppressed. LARGE SCALE DATA: None. LIMITATIONS REASONS FOR CAUTION: Luteinized granulosa cells may differ from luteal cells, and the effect on luteal function in vivo was not directly tested. The mechanisms that cause the initial rise in CYP27A1 mRNA expression during luteolysis are also not clear. WIDER IMPLICATIONS OF THE FINDINGS: The factors causing luteolysis in primates have not yet been determined. This study provides functional evidence of a novel mechanism via increased 27OH synthesis during luteolysis, which subsequently represses progesterone secretion. Increased 27OH may also facilitate the progression of luteolysis in domestic animal species. STUDY FUNDING AND COMPETING INTEREST(S): The authors have nothing to disclose.

AB - A gradual shift in the microfibril angle of gelatinous layer (G-layer) of tension wood fibres of the S1+G type has been detected via potassium permanganate (KMnO4) staining. Thus, microfibril angles in fibres of the S1+G type are different from S1+S2+G type fibres. We evaluated the microfibril orientation and presence of lignin and xylan in G-layers of tension wood fibres of the S1+G type in several Japanese hardwoods. The distribution of xylan and lignin was examined using immunoelectron microscopy with anti-xylan monoclonal antibody, ultraviolet (UV) microscopy, fluorescence microscopy after acrifravine staining and transmission electron microscopy after KMnO4 staining. In transverse sections, the outer parts of the G-layers showed ultraviolet absorption and a heterogeneous KMnO4 staining pattern, suggesting that lignin was heterogeneously distributed in the outer parts of the G-layers. The heterogeneous staining pattern was found in the G layers of several tree species; however, the degree of staining differed between tree species. In longitudinal sections, the KMnO4-staining region in the G-layers continued parallel to the cell axis to variable lengths. The orientation of cellulose microfibrils changed gradually from a steep helix to parallel to the cell axis from the outer to inner parts of the G-layers. Xylan immunolabelling was observed in the outer part of the G-layers; in some fibres, labelling was found in the innermost parts of the G-layers. Following immunogold labelling combined with KMnO4 staining, xylan labelling was mainly found in KMnO4-stained electron-opaque regions, suggesting that lignin and xylan were heterogeneously colocalized in the outer parts of the G-layers. The rotation of cellulose microfibrils and heterogeneous distribution of xylan and lignin might be a general phenomenon in S1+G tension wood fibres. PMID- 29177444 TI - Derivation of nearest-neighbor DNA parameters in magnesium from single molecule experiments. AB - DNA hybridization is an essential molecular reaction in biology with many applications. The nearest-neighbor (NN) model for nucleic acids predicts DNA thermodynamics using energy values for the different base pair motifs. These values have been derived from melting experiments in monovalent and divalent salt and applied to predict melting temperatures of oligos within a few degrees. However, an improved determination of the NN energy values and their salt dependencies in magnesium is still needed for current biotechnological applications seeking high selectivity in the hybridization of synthetic DNAs. We developed a methodology based on single molecule unzipping experiments to derive accurate NN energy values and initiation factors for DNA. A new set of values in magnesium is derived, which reproduces unzipping data and improves melting temperature predictions for all available oligo lengths, in a range of temperature and salt conditions where correlation effects between the magnesium bound ions are weak. The NN salt correction parameters are shown to correlate to the GC content of the NN motifs. Our study shows the power of single-molecule force spectroscopy assays to unravel novel features of nucleic acids such as sequence-dependent salt corrections. PMID- 29177445 TI - Do sleeping habits mediate the association between time spent on digital devices and school problems in adolescence? AB - Background: This study examined the associations of Internet and computer screen time with school difficulties and the role of sleep quality and soft and energy drinks consumption. Methods: We used data from the cross-sectional Health Behaviour in School-aged Children study collected in 2014 among Slovak adolescents (aged 11.0-15.9 years, N = 7595, 48.1% boys). We examined the inter relations between time spent with on digital devices (time spent playing digital games or Internet use), sleeping quality (sleeping shortage, sleeping difficulties), soft/energy drinks consumption and school problems (low academic achievement, disliking school, being pressured by schoolwork and truancy), using structural equation modeling. Results: Results showed that the more time adolescents spent on digital devices during leisure time, the more school problems they had. This association was mediated by a higher consumption of soft or energy drinks and a lower quality of sleeping. The direct effect of time spent on digital devices on school problems and its indirect effect via sleeping quality were relatively small (-0.26 and -0.30, respectively, standardized solution), compared with the indirect effect of time spent on digital devices via soft/energy drinks consumption as well as sleeping quality (0.65, standardized solution). Conclusions: Time spent on digital devices is associated with school problems, with sleeping and soft/energy drinks consumption playing a substantial role in this association.

AB - Background: Echinocandins are recommended as first-line therapy against Candida glabrata infections, although increased resistance to this class has been reported worldwide and they are currently only available for parenteral administration. SCY-078 is an investigational glucan synthase inhibitor that is orally available. Objectives: To evaluate the in vivo efficacy of SCY-078 in an experimental model of invasive candidiasis due to WT and echinocandin-resistant C. glabrata isolates. Methods: Neutropenic ICR mice were inoculated intravenously with a WT isolate (SCY-078 and caspofungin MICs 0.25 and 0.125 mg/L, respectively) or an echinocandin-resistant isolate (SCY-078 and caspofungin MICs 1 and 0.5 mg/L, respectively). Treatment with placebo, SCY-078 (8, 30 or 40 mg/kg orally every 12 h) or caspofungin (1 mg/kg by intraperitoneal injection once daily) began 24 h later. Kidney fungal burden was measured on day 8 post inoculation. Results: Significant reductions in kidney fungal burden were observed with 30 mg/kg SCY-078 against both isolates and with the 40 mg/kg dose against the echinocandin-resistant isolate. These results were supported by SCY 078 plasma concentration data at the higher doses, where levels above the MICs for both isolates were observed 12 h after the last oral dose. Reductions in fungal burden were also observed with caspofungin against the WT isolate, but not against the resistant isolate. Conclusions: SCY-078 demonstrated in vivo efficacy against infections caused by both WT and echinocandin-resistant C. glabrata isolates in this experimental model. This orally available glucan synthase inhibitor has potential as a therapy against echinocandin-resistant C. glabrata infections.

AB - OBJECTIVES: The benefits of concomitant tricuspid annuloplasty (TAP) for non significant functional tricuspid regurgitation (TR) during mitral valve replacement (MVR) are controversial. We evaluated the long-term outcomes particularly the long-term tricuspid valve (TV) functional outcomes-of MVR with or without tricuspid ring annuloplasty. METHODS: From 2004 to 2014, 256 patients (56.4 +/- 12.1 years) with trivial or mild functional TR who underwent MVR were enrolled. Eighty-two patients underwent concomitant tricuspid ring annuloplasty (TAP group), and 174 patients did not undergo the TV procedure (nTAP group). Propensity score-matched analysis was performed (n = 72 in each group). The follow-up duration was 77.4 +/- 42.4 months. RESULTS: The early clinical outcomes were similar between the 2 groups before and after propensity score matching with an early mortality rate of 3.5% (9 of 256). No patients experienced ring-related complications during follow-up. Eleven (6.3%) patients developed significant TR (>=moderate) in the nTAP group, while no patients developed significant TR in the TAP group. There were no significant differences in overall survival between the 2 groups before or after matching. However, propensity score-matched analysis revealed that the freedom from significant TR aggravation and freedom from TV related event rates were significantly higher in the TAP group than in the nTAP group (P = 0.047 and P = 0.043, respectively). CONCLUSIONS: Patients with untreated trivial or mild functional TR accompanied by mitral valve disease can develop significant TR during follow-up. TV ring annuloplasty can be performed without complications and can be beneficial for patients with trivial or mild functional TR who are undergoing MVR.

AB - Ozone is a highly oxidizing gas with insecticidal activity and it is a potential alternative to conventional fumigants, such as phosphine and methyl bromide, for managing stored product insects. Susceptibility of the merchant grain beetle, Oryzaephilus mercator (Fauvel; Coleoptera: Silvanidae), an important pest of stored products, to ozone treatments is unknown. In this study, we investigated the efficacy of ozone for controlling O. mercator. We determined concentration mortality relationships for all stages of O. mercator exposed to 100-400 ppm for 1 h (1 g/m3 = 467 ppm). We also determined time-mortality relationships for adults exposed to 100 ppm for 1-6 h. Mortality was recorded as percentages of eggs that failed to hatch 10 days after treatment (DAT), larvae or pupae that failed to develop into adults 20 or 15 DAT, respectively, and adults that died 2 DAT. Generally, mortality increased with an increase in ozone concentration. Mortality was higher when insects were treated without food. When food was not provided, a minimum of 11030 ppm for 1 h is required to kill 99% of eggs, the most tolerant stage, whereas 500 ppm for 1 h is required to kill 99% of larvae, the least tolerant. When provided with food, adults were the most tolerant and larvae the least tolerant. Adults require exposure time of 7.7 h of 100 ppm ozone to kill 99% of insects in the absence of food. The work reported suggests that ozone could be an alternative fumigant for the management of all O. mercator life stages. PMID- 29177446 TI - A physiological perspective on the origin and evolution of photosynthesis. AB - The origin and early evolution of photosynthesis are reviewed from an ecophysiological perspective. Earth's first ecosystems were chemotrophic, fueled by geological H2 at hydrothermal vents and, required flavin-based electron bifurcation to reduce ferredoxin for CO2 fixation. Chlorophyll-based phototrophy (chlorophototrophy) allowed autotrophs to generate reduced ferredoxin without electron bifurcation, providing them access to reductants other than H2. Because high-intensity, short-wavelength electromagnetic radiation at Earth's surface would have been damaging for the first chlorophyll (Chl)-containing cells, photosynthesis probably arose at hydrothermal vents under low-intensity, long wavelength geothermal light. The first photochemically active pigments were possibly Zn-tetrapyrroles. We suggest that (i) after the evolution of red absorbing Chl-like pigments, the first light-driven electron transport chains reduced ferredoxin via a type-1 reaction center (RC) progenitor with electrons from H2S; (ii) photothioautotrophy, first with one RC and then with two, was the bridge between H2-dependent chemolithoautotrophy and water-splitting photosynthesis; (iii) photothiotrophy sustained primary production in the photic zone of Archean oceans; (iv) photosynthesis arose in an anoxygenic cyanobacterial progenitor; (v) Chl a is the ancestral Chl; and (vi), anoxygenic chlorophototrophic lineages characterized so far acquired, by horizontal gene transfer, RCs and Chl biosynthesis with or without autotrophy, from the architects of chlorophototrophy-the cyanobacterial lineage.

In Brazil, most of the neutron occupational fields are from radionuclide sources, often without any moderation, where albedo dosemeters have poor energy response. The purpose of this work is to compare the HP(10) energy response of the IRD and ALNOR TLD albedo dosemeter systems, calculated by their modelling with Monte Carlo code MCNPX. Their energy responses are similar, as expected, but the IRD system is about five times more sensitive than the ALNOR one. IRD albedo system can measure the Brazilian monthly recording level of 0.2 mSv, even for bare 252Cf and 241Am-Be neutron fields. On the other hand, the ALNOR system can measure values higher than 0.2 mSv only after huge moderation of theses sources. These results show that IRD TLD albedo is more suitable than the ALNOR one to measure low doses at occupational fields from radionuclide sources. PMID- 29177452 TI - Effects of an internet-based educational intervention to prevent high-risk sexual behavior in Mexican adolescents. AB - : To evaluate the effect of an internet-based educational intervention to increase knowledge of sexually transmitted infections (STIs), attitudes and self efficacy toward consistent condom use in Mexican adolescents. A field trial with an intervention and control group was conducted in 14- to 15-year-old students in two secondary schools. The intervention was delivered via a website that included four educational sessions during a 4-week period and six 30-min class discussions during a 3-month period. In the control group, the investigators observed the general sex education provided by the school. Outcome variables were 1) knowledge about STIs, 2) attitudes regarding condom use, and 3) self-efficacy toward consistent condom use. Differences-in-differences (Diff-in-Diff) treatment effect was estimated for each outcome variable. There were 246 adolescents in the intervention group and 210 in the control group. The intervention had a positive effect on improving knowledge of STIs, attitudes and self-efficacy toward consistent condom use. The major effect was observed on adolescents' knowledge on STIs (Diff-in-Diff 30.34 points, P < 0.0001). A youth-friendly, culturally contextualized, internet-based educational intervention complemented by class discussions may be a significant addition to the regular secondary school sex education program to improve knowledge of STIs, attitudes and self-efficacy toward consistent condom use among adolescents.

AB - Objectives: To examine the test-retest reliability of the DSM-IV Adult ADHD Self Report Scale (ASRS) v1.1 Screener in adults without ADHD. Prior studies have not examined test-retest reliability of the Screener in non-ADHD controls. Methods: Subjects completed the Screener in a primary care physician (PCP) waiting room (T1); those who screened negative for ADHD (n = 104) (<4/6 significant Screener items) symptoms were further assessed on the phone (T2). T2 included phone administration of the full ASRS v1.1 Symptom Checklist (which contains the six items from the Screener). Spearman's correlations and intra-class correlation coefficients (ICCs) between T1 and T2 were calculated for the total Screener score and for each Screener item. McNemar-Bowker tests were conducted for the Screener total score and each item to check for significant changes from T1 to T2. Results: Screener T1 and T2 total scores were significantly correlated (Spearman's rho = 0.78, P < 0.0001), as were individual items. Correlations remained significant when controlling for a variety of demographic factors and psychiatric conditions. Confirming the significant Spearman correlations, ICCs for Screener total score and each item were also significant (ICC = 0.75, P < 0.0001). The McNemar-Bowker tests showed no significant differences for Screener total score and for the IA items; however, the H-I items were somewhat higher at T1 versus T2. Conclusions: The DSM-IV ASRS v1.1 Screener has high test-retest reliability in patients without ADHD. PMID- 29177455 TI - Investigating commercial in ovo technology as a strategy for introducing probiotic bacteria to broiler embryos. AB - Probiotics can improve broiler performance and reduce pathogens. Because the hatchery can be a source of contamination, delivering probiotics to the embryo before hatch is desirable. To date, probiotics have primarily been injected into eggs manually. Therefore, the objective of this study was to deliver various probiotic bacteria into broiler hatching eggs using an automated commercial in ovo injection system to evaluate hatchability of fertile eggs (HF). Three separate experiments were conducted using Lactobacillus acidophilus, Bacillus subtilis, or Bifidobacterium animalis. In each experiment, 7 treatments (non injected control; dry punch control; diluent-injected control; and injections of 103 cfu, 104 cfu, 105 cfu, or 106 cfu of bacteria/50 MUL of diluent) were evaluated using 10 replicates per treatment. For each experiment, 2,490 eggs were obtained from a commercial hatchery. Eggs were incubated under standard incubation conditions. At 10 d of incubation (doi), eggs were candled, and infertile eggs were removed. On 18 doi, all eggs were injected with the appropriate treatment using an automated in ovo injection system. Once all eggs were injected, they were transferred to hatching baskets and placed into the hatcher. On 21 doi, chicks were removed from the hatcher, counted, and weighed. Hatch residue analysis was conducted to determine infertile, early dead, mid dead, late dead, pipped, cracked, contaminated, and cull chick statuses of all unhatched eggs. Injecting L. acidophilus, even at a concentration as high as 106 cfu/50 MUL, did not impact hatch residue analysis (P > 0.05). However, HF was significantly less for eggs treated with B. subtilis than for control eggs (P < 0.0001). For the non-injected control, HF was 91%, but as concentration of B. subtilis increased, HF decreased to as low as 1.67% for the 105 cfu treatment. Late deads, pipped, and contaminated egg percentages were higher, and chick BW was lower for B. subtilis treatment groups compared to controls. In conclusion, L. acidophilus and B. animalis but not B. subtilis, appear to be suitable candidates for in ovo injection as probiotics.

AB - Our knowledge of how the human brain differs from those of other species in terms of evolutionary adaptations and functionality is limited. Comparative genomics reveal valuable insight, especially the expansion of human-specific noncoding regulatory and repeat-containing regions. Recent studies add to our knowledge of evolving brain function by investigating cellular mechanisms such as protein emergence, extensive sequence editing, retrotransposon activity, dynamic epigenetic modifications, and multiple noncoding RNA functions. These findings present an opportunity to combine newly discovered genetic and epigenetic mechanisms with more established concepts into a more comprehensive picture to better understand the uniquely evolved human brain. PMID- 29177454 TI - Factors influencing the activation of the rapid response system for clinically deteriorating patients by frontline ward clinicians: a systematic review. AB - Purpose: To synthesize factors influencing the activation of the rapid response system (RRS) and reasons for suboptimal RRS activation by ward nurses and junior physicians. Data sources: Nine electronic databases were searched for articles published between January 1995 and January 2016 in addition to a hand-search of reference lists and relevant journals. Study selection: Published primary studies conducted in adult general ward settings and involved the experiences and views of ward nurses and/or junior physicians in RRS activation were included. Data extraction: Data on design, methods and key findings were extracted and collated. Results of data synthesis: Thirty studies were included for the review. The process to RRS activation was influenced by the perceptions and clinical experiences of ward nurses and physicians, and facilitated by tools and technologies, including the sensitivity and specificity of the activation criteria, and monitoring technology. However, the task of enacting the RRS activations was challenged by seeking further justification, deliberating over reactions from the rapid response team and the impact of workload and staffing. Finally, adherence to the traditional model of escalation of care, support from colleagues and hospital leaders, and staff training were organizational factors that influence RRS activation. Conclusion: This review suggests that the factors influencing RRS activation originated from a combination of socio-cultural, organizational and technical aspects. Institutions that strive for improvements in the existing RRS or are considering to adopt the RRS should consider the complex interactions between people and the elements of technologies, tasks, environment and organization in healthcare settings. PMID- 29177457 TI - Assessing the capacity of social determinants of health data to augment predictive models identifying patients in need of wraparound social services. AB - Introduction: A growing variety of diverse data sources is emerging to better inform health care delivery and health outcomes. We sought to evaluate the capacity for clinical, socioeconomic, and public health data sources to predict the need for various social service referrals among patients at a safety-net hospital. Materials and Methods: We integrated patient clinical data and community-level data representing patients' social determinants of health (SDH) obtained from multiple sources to build random forest decision models to predict the need for any, mental health, dietitian, social work, or other SDH service referrals. To assess the impact of SDH on improving performance, we built separate decision models using clinical and SDH determinants and clinical data only. Results: Decision models predicting the need for any, mental health, and dietitian referrals yielded sensitivity, specificity, and accuracy measures ranging between 60% and 75%. Specificity and accuracy scores for social work and other SDH services ranged between 67% and 77%, while sensitivity scores were between 50% and 63%. Area under the receiver operating characteristic curve values for the decision models ranged between 70% and 78%. Models for predicting the need for any services reported positive predictive values between 65% and 73%. Positive predictive values for predicting individual outcomes were below 40%. Discussion: The need for various social service referrals can be predicted with considerable accuracy using a wide range of readily available clinical and community data that measure socioeconomic and public health conditions. While the use of SDH did not result in significant performance improvements, our approach represents a novel and important application of risk predictive modeling. PMID- 29177458 TI - A Survey of Physicians' Knowledge and Adherence to the Diagnostic Criteria for Fibromyalgia. AB - Objective: In 2010, Wolfe et al. demonstrated poor physician use of the 1990 fibromyalgia diagnostic criteria and proposed the 2010 criteria to address physician shortcomings. No follow-up studies have investigated whether physicians are using these criteria. The purpose of this study was to provide seminal data on physician knowledge and use of the fibromyalgia diagnostic criteria. Methods: This was an observational study. A questionnaire was distributed to a convenience sample of physicians who diagnose chronic pain conditions. Physician agreement was evaluated with statements testing their knowledge on the fibromyalgia criteria, and then intraclass correlations were calculated to determine the homogeneity of physicians' responses. We also determined whether physician knowledge was impacted by their specialist training and clinical experience. Results: Physician responses varied between correct and incorrect agreement on most questions. Physician specialist training was positively correlated with knowledge of the criteria. Physician knowledge overall was not comprehensive and was very poor for the 1990 and 2010 criteria. Fifty-one percent of physicians used a set of criteria in their practice, and 49% used their clinical acumen. Conclusions: Physicians do not have adequate and homogenous knowledge of the fibromyalgia diagnostic criteria. Approximately half of physicians did not adhere to the criteria. Poor knowledge and adherence to the criteria may increase diagnosis delays and misdiagnoses. Knowledge translation strategies should be implemented to address this problem. PMID- 29177459 TI - Acclimation of branch and leaf hydraulics in adult Fagus sylvatica and Picea abies in a forest through-fall exclusion experiment. AB - Decreasing water availability due to climate change poses the question of whether and to what extent tree species are able to hydraulically acclimate and how hydraulic traits of stems and leaves are coordinated under drought. In a through fall exclusion experiment, hydraulic acclimation was analyzed in a mixed forest stand of Fagus sylvatica L. and Picea abies (L.) Karst. In drought-stressed (TE, through-fall exclusion over 2 years) and control (CO) trees, hydraulic vulnerability was studied in branches as well as in leaves (F. sylvatica) and end twigs (P. abies, entirely formed during the drought period) sampled at the same height in sun-exposed portions of the tree crown. In addition, relevant xylem anatomical traits and leaf pressure-volume relations were analyzed. The TE trees reached pre-dawn water potentials down to -1.6 MPa. In both species, water potentials at 50% loss of xylem hydraulic conductivity were ~0.4 MPa more negative in TE than in CO branches. Foliage hydraulic vulnerability (expressed as water potential at 50% loss of leaf/end-twig hydraulic conductance) and water potential at turgor loss point were also, respectively, 0.4 and 0.5 MPa lower in TE trees. Minor differences were observed in conduit mean hydraulic diameter and cell wall reinforcement. Our findings indicate significant and fast hydraulic acclimation under relatively mild drought in both tree species. Acclimation was well coordinated between branches and foliage, which might be essential for survival and productivity of mature trees under future drought periods.

PMID- 29177461 TI - Rigorous Clinical Trial Design in Public Health Emergencies Is Essential. AB - Randomized clinical trials are the most reliable approaches to evaluating the effects of new treatments and vaccines. During the 2014-2015 West African Ebola epidemic, many argued that such trials were neither ethical nor feasible in an environment of limited health infrastructure and severe disease with a high fatality rate. Consensus among the numerous organizations providing help to the affected areas was never achieved, resulting in fragmented collaboration, delayed study initiation, and ultimately failure to provide definitive evidence on the efficacy of treatments and vaccines. Randomized trials were in fact approved by local ethics boards and initiated, demonstrating that randomized trials, even in such difficult circumstances, are feasible. Improved planning and collaboration among research and humanitarian organizations, and affected communities, in the interepidemic periods are needed to ensure that questions regarding the efficacy of vaccines and treatments can be definitively answered during future public health emergencies. PMID- 29177463 TI - Elevated potassium levels in patients with chronic kidney disease: occurrence, risk factors and clinical outcomes-a Danish population-based cohort study. AB - Background: Data on the true burden of hyperkalemia (HK) in patients with chronic kidney disease (CKD) in a real-world setting are scarce. Methods: The incidence rate of HK [first blood test with an elevated blood potassium level level >5.0 mmol/L] in primary or hospital care was assessed in a population-based cohort of all newly diagnosed CKD patients [second estimated glomerular filtration rate (eGFR) measurement <60 mL/min/1.73 m 2 or hospital diagnosis] in northern Denmark. Risk factors and clinical outcomes were compared for CKD patients with HK and matched CKD patients without HK. Results: Of 157 766 patients with CKD, 28% experienced HK, for an overall HK incidence rate of 70/1000 person-years. Among patients with Stage 3A, 3B, 4 or 5 CKD, 9, 18, 31 and 42%, respectively, experienced HK within the first year. Important HK risk factors included diabetes {prevalence ratio [PR] 1.74 [95% confidence interval (CI) 1.69-1.79]}, heart failure [PR 2.31 (95% CI 2.23-2.40)] and use of angiotensin-converting enzyme inhibitors [PR 1.45 (95% CI 1.42-1.48)], potassium supplements [PR 1.59 (95% CI 1.55-1.62)] or spironolactone [PR 2.53 (95% CI 2.44-2.63)]. In CKD patients who developed HK, 34% had any acute hospitalization 6 months before the HK event, increasing to 57% 6 months after HK [before-after risk ratio 1.72 (95% CI 1.69 1.74)]. The 6-month mortality following HK was 26%, versus 6% in matched non-HK patients. Compared with non-HK patients, 6-month hazard ratios for any acute hospitalization in HK patients were 2.11-fold higher, including hazard ratios of 2.07 for cardiac diagnoses, 2.29 for ventricular arrhythmias, 3.26 for cardiac arrest, 4.77 for intensive care and 4.85 for death. Conclusions: More than one in four CKD patients develops HK. Patients with severe CKD, diabetes, heart failure or use of spironolactone are at high risk. HK is associated with severe clinical outcomes. PMID- 29177464 TI - QVZ: lossy compression of quality values.

PMID- 29177465 TI - Aminoglycoside-mediated promotion of translation readthrough occurs through a non stochastic mechanism that competes with translation termination. AB - Attempts have been made to treat nonsense-associated genetic disorders by chemical agents and hence an improved mechanistic insight into the decoding of readthrough signals is essential for the identification and characterisation of factors for the treatment of these disorders. To identify either novel compounds or genes that modulate translation readthrough, we have employed dual reporter based high-throughput screens that use enzymatic and fluorescence activities and screened bioactive National Institute of Neurological Disease Syndrome (NINDS) compounds (n = 1000) and siRNA (n = 288) libraries. Whilst siRNAs targeting kinases such as CSNK1G3 and NME3 negatively regulate readthrough, neither the bioactive NINDS compounds nor PTC124 promote readthrough. Of note, PTC124 has previously been shown to promote readthrough. Furthermore, the impacts of G418 on the components of eukaryotic selenocysteine incorporation machinery have also been investigated. The selenocysteine machinery decodes the stop codon UGA specifying selenocysteine in natural selenoprotein genes. We have found that the eukaryotic SelC gene promotes the selenocysteine insertion sequence (SECIS) mediated readthrough but inhibits the readthrough activity induced by G418. We have previously reported that SECIS-mediated readthrough at UGA codons follows a non-processive mechanism. Here, we show that G418-mediated promotion of readthrough also occurs through a non-processive mechanism which competes with translation termination. Based on our observations, we suggest that proteins generated through a non-processive mechanism may be therapeutically beneficial for the resolution of nonsense-associated genetic disorders. PMID- 29177467 TI - True Pathogen or Contamination: Validation of Blood Cultures for the Diagnosis of Nosocomial Infections in a Developing Country. AB - Background: Blood culture results are frequently used to guide antibiotic decision-making, but culture contaminants need to be distinguished from true pathogens. Aims: To assess the contamination rate of blood cultures and validate a method to distinguish between true bacteraemia and contamination. Methods: We analysed blood culture results from children who were admitted to the paediatric ICU and paediatric wards at the Sardjito Hospital, Yogyakarta, Indonesia between December 2010 and February 2013. For each positive culture result, the type of isolated organism, time to positivity, and the number of positive culture sites were considered to classify the isolate as representing a true bacteraemia or contaminant. Results: There were 1293 cultures obtained from blood and 308 (23.8%) were positive for bacterial growth. Fifty-three (4.1%) of the total cultures drawn fulfilled criteria for contaminants. The most common blood culture contaminants were coagulase-negative staphylococci. Conclusion: Using standardized criteria, it is possible to implement a working method to identify true nosocomial infection from blood culture contaminant, and thus limit the effect of contaminated blood culture on irrational antibiotic use. PMID- 29177466 TI - Modeling RNA secondary structure folding ensembles using SHAPE mapping data. AB - RNA secondary structure prediction is widely used for developing hypotheses about the structures of RNA sequences, and structure can provide insight about RNA function. The accuracy of structure prediction is known to be improved using experimental mapping data that provide information about the pairing status of single nucleotides, and these data can now be acquired for whole transcriptomes using high-throughput sequencing. Prior methods for using these experimental data focused on predicting structures for sequences assuming that they populate a single structure. Most RNAs populate multiple structures, however, where the ensemble of strands populates structures with different sets of canonical base pairs. The focus on modeling single structures has been a bottleneck for accurately modeling RNA structure. In this work, we introduce Rsample, an algorithm for using experimental data to predict more than one RNA structure for sequences that populate multiple structures at equilibrium. We demonstrate, using SHAPE mapping data, that we can accurately model RNA sequences that populate multiple structures, including the relative probabilities of those structures. This program is freely available as part of the RNAstructure software package. PMID- 29177469 TI - Erratum.

AB - Objective: to investigate whether cognitive impairment, measured early after Emergency Department (ED) arrival and irrespective of its cause, is independently associated with functional decline or mortality after 3 and 12 months in older ED patients. Design and setting: a prospective multi-centre cohort study in all Acutely Presenting Older Patients visiting the Emergency Department (APOP study) of three hospitals in the Netherlands. Participants: 2,130 patients, >=70 years. Measurements: data on demographics, disease severity and geriatric characteristics were collected during the first hour of the ED visit. Cognition was measured using the 6-Item-Cognitive-Impairment-Test ('6CIT'). Cognitive impairment was defined as 6CIT >=11, self-reported dementia or the inability to perform the cognition test. The composite adverse outcome after 3 and 12 months was defined as a 1-point decrease in Katz Activities of Daily Living (ADL), new institutionalisation or mortality. Multivariable regression analysis was used to assess whether cognitive impairment independently associates with adverse outcome. Results: of 2,130 included patients, 588 (27.6%) had cognitive impairment at baseline and 654 patients (30.7%) suffered from adverse outcome after 3 months. Cognitive impairment associated with increased risk for adverse outcome (adjusted odds ratio (OR) 1.72, 95%CI 1.37-2.17). After 12 months, 787 patients (36.9%) suffered from adverse outcome. Again, cognitive impairment independently associated with increased risk for adverse outcome (adjusted OR 1.89, 95%CI 1.46-2.46). ORs were similar for patients who were discharged home versus hospitalised patients. Conclusion: cognitive impairment measured during the early stages of ED visit, irrespective of the cause, is independently associated with adverse outcome after 3 and 12 months in older patients. PMID- 29177471 TI - Long-Term Improvement in Aortic Pulse Wave Velocity After Weight Loss Can Be Predicted by White Adipose Tissue Factors. AB - BACKGROUND: Arterial stiffness, measured by pulse wave velocity (PWV), is linked to obesity, cardiovascular disease, and all-cause mortality. Short-term weight loss improves PWV, but the long-term effects are unknown. We investigated the effect of pronounced long-term weight loss on PWV and whether anthropometric/metabolic parameters and/or white adipose tissue (WAT) phenotype could predict this change in PWV. METHODS: Eighty-two obese subjects were examined before and 2 years after Roux-en-Y gastric bypass. Analyses included anthropometrics, routine clinical chemistry, and hyperinsulinemic-euglycemic clamp. Arterial stiffness was measured as aortic PWV (aPWV) using the Arteriograph device. WAT mass and distribution were assessed by dual-X-ray absorptiometry. Baseline visceral and subcutaneous WAT samples were obtained to measure adipocyte cell size. Transcriptomic profiling of subcutaneous WAT was performed in a subset of subjects (n = 30). RESULTS: At the 2-year follow-up, there were significant decreases in body mass index (39.4 +/- 3.5 kg/m2 vs. 26.6 +/- 3.4 kg/m2; P < 0.0001) and aPWV (7.8 +/- 1.5 m/s vs. 7.2 +/- 1.4 m/s; P = 0.006). Multiple regression analyses showed that baseline subcutaneous adipocyte volume was associated with a reduction in aPWV (P = 0.014), after adjusting for confounders. Expression analyses of 52 genes implicated in arterial stiffness showed that only one, COL4A1, independently predicted improvements in aPWV after adjusting for confounders (P = 0.006). CONCLUSIONS: Bariatric surgery leads to long-term reduction in aPWV. This improvement can be independently predicted by subcutaneous adipocyte volume and WAT COL4A1 expression, which suggests that subcutaneous WAT has a role in regulating aPWV.

In this study, we investigated the mRNA and protein expression of selected Cyp's in mice subjected to 16 weeks of HFD and treadmill running. To understand the regulatory mechanisms behind the exercise-induced reversion of the HFD-induced changes in Cyp expression, we used a model in which the exercise-induced myokine and known regulator of hepatic Cyp's, interleukin-6 (IL-6), were knocked out specifically in skeletal muscle. We found that HFD increased the mRNA expression of Cyp1a1 and Cyp4a10, and decreased the expression of Cyp2a4, Cyp2b10, Cyp2e1, and Cyp3a11. HFD in combination with treadmill running reversed the HFD increase in Cyp4a10 mRNA expression. In addition, we observed increased Cyp1a and Cyp3a protein expression as an effect of exercise, whereas Cyp2b expression was lowered as an effect of HFD. IL-6 effected the response in Cyp3a11 and Cyp1a expression. We observed no changes in the content of the aryl hydrocarbon receptor, constitutive androstane receptor, pregnane X receptor, or peroxisome proliferation activator receptor alpha. In conclusion, we show that both HFD and exercise in HFD-fed animals can regulate hepatic Cyp expression and that changes in Cyp3a in response to HFD and exercise are dependent on skeletal muscular IL-6.

AB - The sizes of the data matrices assembled to resolve branches of the tree of life have increased dramatically, motivating the development of programs for fast, yet accurate, inference. For example, several different fast programs have been developed in the very popular maximum likelihood framework, including RAxML/ExaML, PhyML, IQ-TREE, and FastTree. Although these programs are widely used, a systematic evaluation and comparison of their performance using empirical genome-scale data matrices has so far been lacking. To address this question, we evaluated these four programs on 19 empirical phylogenomic data sets with hundreds to thousands of genes and up to 200 taxa with respect to likelihood maximization, tree topology, and computational speed. For single-gene tree inference, we found that the more exhaustive and slower strategies (ten searches per alignment) outperformed faster strategies (one tree search per alignment) using RAxML, PhyML, or IQ-TREE. Interestingly, single-gene trees inferred by the three programs yielded comparable coalescent-based species tree estimations. For concatenation-based species tree inference, IQ-TREE consistently achieved the best-observed likelihoods for all data sets, and RAxML/ExaML was a close second. In contrast, PhyML often failed to complete concatenation-based analyses, whereas FastTree was the fastest but generated lower likelihood values and more dissimilar tree topologies in both types of analyses. Finally, data matrix properties, such as the number of taxa and the strength of phylogenetic signal, sometimes substantially influenced the programs' relative performance. Our results provide real-world gene and species tree phylogenetic inference benchmarks to inform the design and execution of large-scale phylogenomic data analyses.

AB - Aims: This randomized single-centre study sought to compare the efficacy and safety of pulmonary vein isolation (PVI) plus voltage-guided ablation vs. PVI with or without linear ablation depending on the type of atrial fibrillation (AF). Methods and results: Overall, 124 ablation-naive patients with paroxysmal or persistent AF were randomized to PVI with (persistent AF) or without (paroxysmal AF) additional linear ablation (control group) vs. PVI plus ablation of low-voltage areas (LVAs) irrespective of AF type. Bipolar voltage mapping was performed during stable sinus rhythm. An LVA consisted of >= 3 adjacent mapping points that each had a peak-to-peak amplitude <=0.5 mV. After a mean follow-up of 12 +/- 3 months, significantly more patients in the LVA ablation group were free from atrial arrhythmia recurrence >30 s off antiarrhythmic drugs (AADs) after a single procedure (primary endpoint) compared with control group patients [40/59 (68%) vs. 25/59 (42%), log-rank P = 0.003]. Arrhythmia-free survival on or off AADs was found in 33/59 control group patients (56%) and in 41/59 LVA ablation group patients (70%) (adjusted log-rank P = 0.10). During the 7 day Holter monitoring period at 12 months, significantly more patients in the LVA ablation group were free from arrhythmia recurrence on or off AADs [45/50 (90%) vs. 33/46 (72%), P = 0.04]. No between-group differences were observed regarding procedure duration, fluoroscopy time, and major complications. Conclusion: In this single centre study, individually tailored substrate modification guided by voltage mapping was associated with a significantly higher arrhythmia-free survival rate compared with a conventional approach applying linear ablation according to AF type. PMID- 29177476 TI - Functional relationships between wood structure and vulnerability to xylem cavitation in races of Eucalyptus globulus differing in wood density. AB - Wood density can be considered as a measure of the internal wood structure, and it is usually used as a proxy measure of other mechanical and functional traits. Eucalyptus is one of the most important commercial forestry genera worldwide, but the relationship between wood density and vulnerability to cavitation in this genus has been little studied. The analysis is hampered by, among other things, its anatomical complexity, so it becomes necessary to address more complex techniques and analyses to elucidate the way in which the different anatomical elements are functionally integrated. In this study, vulnerability to cavitation in two races of Eucalyptus globulus Labill. with different wood density was evaluated through Path analysis, a multivariate method that allows evaluation of descriptive models of causal relationship between variables. A model relating anatomical variables with wood properties and functional parameters was proposed and tested. We found significant differences in wood basic density and vulnerability to cavitation between races. The main exogenous variables predicting vulnerability to cavitation were vessel hydraulic diameter and fibre wall fraction. Fibre wall fraction showed a direct impact on wood basic density and the slope of vulnerability curve, and an indirect and negative effect over the pressure imposing 50% of conductivity loss (P50) through them. Hydraulic diameter showed a direct negative effect on P50, but an indirect and positive influence over this variable through wood density on one hand, and through maximum hydraulic conductivity (ks max) and slope on the other. Our results highlight the complexity of the relationship between xylem efficiency and safety in species with solitary vessels such as Eucalyptus spp., with no evident compromise at the intraspecific level. PMID- 29177477 TI - Impact of antimicrobial stewardship interventions on Clostridium difficile infection and clinical outcomes: segmented regression analyses. AB - Background: Antimicrobial exposure is associated with increased risk of Clostridium difficile infection (CDI), but the impact of prescribing interventions on CDI and other outcomes is less clear. Objectives: To evaluate the effect of an antimicrobial stewardship intervention targeting high-risk antimicrobials (HRA), implemented in October 2008, and to compare the findings with similar studies from a systematic review. Methods: All patients admitted to Medicine and Surgery in Ninewells Hospital from October 2006 to September 2010 were included. Intervention effects on HRA use (dispensed DDD), CDI cases and mortality rates, per 1000 admissions per month, were analysed separately in Medicine and Surgery using segmented regression of interrupted time series (ITS) data. Data from comparable published studies were reanalysed using the same method. Results: Six months post-intervention, there were relative reductions in HRA use of 33% (95% CI 11-56) in Medicine and 32% (95% CI 19-46) in Surgery. At 12 months, there was an estimated reduction in CDI of 7.0 cases/1000 admissions [relative change -24% (95% CI - 55 to 6)] in Medicine, but no change in Surgery {estimated 0.1 fewer cases/1000 admissions [-2% (95% CI - 116 to 112)]}. Mortality reduced throughout the study period, unaffected by the intervention. In all six comparable studies, HRA use reduced significantly, but reductions in CDI rates were only statistically significant in two and none measured mortality. Pre intervention CDI rates and trends influenced the intervention effect. Conclusions: Despite large reductions in HRA prescribing and reductions in CDI, demonstrating real-world impact of stewardship interventions remains challenging. PMID- 29177478 TI - Manipulation of Bryophyte Hosts by Pathogenic and Symbiotic Microbes. AB - The colonization of plant tissues by pathogenic and symbiotic microbes is associated with a strong and directed effort to reprogram host cells in order to permit, promote and sustain microbial growth. In response to colonization, hosts accommodate or sequester invading microbes by activating a set of complex regulatory programs that initiate symbioses or bolster defenses. Extensive research has elucidated a suite of molecular and physiological responses occurring in plant hosts and their microbial partners; however, this information is mostly limited to model systems representing evolutionarily young plant lineages such as angiosperms. The extent to which these processes are conserved across land plants is therefore poorly understood. In this review, we outline key aspects of host reprogramming that occur during plant-microbe interactions in early diverging land plants belonging to the bryophytes (liverworts, hornworts and mosses). We discuss how further knowledge of bryophyte-microbe interactions will advance our understanding of how plants and microbes co-operated and clashed during the conquest of land. PMID- 29177479 TI - Horizontal Acquisition and Transcriptional Integration of Novel Genes in Mosquito Associated Spiroplasma. AB - Genetic differentiation among symbiotic bacteria is important in shaping biodiversity. The genus Spiroplasma contains species occupying diverse niches and is a model system for symbiont evolution. Previous studies have established that two mosquito-associated species have diverged extensively in their carbohydrate metabolism genes despite having a close phylogenetic relationship. Notably, although the commensal Spiroplasma diminutum lacks identifiable pathogenicity factors, the pathogenic Spiroplasma taiwanense was found to have acquired a virulence factor glpO and its associated genes through horizontal transfer. However, it is unclear if these acquired genes have been integrated into the regulatory network. In this study, we inferred the gene content evolution in these bacteria, as well as examined their transcriptomes in response to glucose availability. The results indicated that both species have many more gene acquisitions from the Mycoides-Entomoplasmataceae clade, which contains several important pathogens of ruminants, than previously thought. Moreover, several acquired genes have higher expression levels than the vertically inherited homologs, indicating possible functional replacement. Finally, the virulence factor and its functionally linked genes in S. taiwanense were up-regulated in response to glucose starvation, suggesting that these acquired genes are under expression regulation and the pathogenicity may be a stress response. In summary, although differential gene losses are a major process for symbiont divergence, gene gains are critical in counteracting genome degradation and driving diversification among facultative symbionts. PMID- 29177481 TI - CDYL1 fosters double-strand break-induced transcription silencing and promotes homology-directed repair. AB - Cells have evolved DNA damage response (DDR) to repair DNA lesions and thus preserving genomic stability and impeding carcinogenesis. DNA damage induction is accompanied by transient transcription repression. Here, we describe a previously unrecognized role of chromodomain Y-like (CDYL1) protein in fortifying double strand break (DSB)-induced transcription repression and repair. We showed that CDYL1 is rapidly recruited to damaged euchromatic regions in a poly (ADP-ribose) polymerase 1 (PARP1)-dependent, but ataxia telangiectasia mutated (ATM) independent, manner. While the C-terminal region, containing the enoyl-CoA hydratase like (ECH) domain, of CDYL1 binds to poly (ADP-ribose) (PAR) moieties and mediates CDYL1 accumulation at DNA damage sites, the chromodomain and histone H3 trimethylated on lysine 9 (H3K9me3) mark are dispensable for its recruitment. Furthermore, CDYL1 promotes the recruitment of enhancer of zeste homolog 2 (EZH2), stimulates local increase of the repressive methyl mark H3K27me3, and promotes transcription silencing at DSB sites. In addition, following DNA damage induction, CDYL1 depletion causes persistent G2/M arrest and alters H2AX and replication protein A (RPA2) phosphorylation. Remarkably, the 'traffic-light reporter' system revealed that CDYL1 mainly promotes homology-directed repair (HDR) of DSBs in vivo. Consequently, CDYL1-knockout cells display synthetic lethality with the chemotherapeutic agent, cisplatin. Altogether, our findings identify CDYL1 as a new component of the DDR and suggest that the HDR-defective 'BRCAness' phenotype of CDYL1-deficient cells could be exploited for eradicating cancer cells harboring CDYL1 mutations. PMID- 29177480 TI - Comparative Genomic Analysis of Acanthamoeba Endosymbionts Highlights the Role of Amoebae as a "Melting Pot" Shaping the Rickettsiales Evolution. AB - Amoebae have been considered as a genetic "melting pot" for its symbionts, facilitating genetic exchanges of the bacteria that co-inhabit the same host. To test the "melting pot" hypothesis, we analyzed six genomes of amoeba endosymbionts within Rickettsiales, four of which belong to Holosporaceae family and two to Candidatus Midichloriaceae. For the first time, we identified plasmids in obligate amoeba endosymbionts, which suggests conjugation as a potential mechanism for lateral gene transfers (LGTs) that underpin the "melting pot" hypothesis. We found strong evidence of recent LGTs between the Rickettsiales amoeba endosymbionts, suggesting that the LGTs are continuous and ongoing. In addition, comparative genomic and phylogenomic analyses revealed pervasive and recurrent LGTs between Rickettsiales and distantly related amoeba-associated bacteria throughout the Rickettsiales evolution. Many of these exchanged genes are important for amoeba-symbiont interactions, including genes in transport system, antibiotic resistance, stress response, and bacterial virulence, suggesting that LGTs have played important roles in the adaptation of endosymbionts to their intracellular habitats. Surprisingly, we found little evidence of LGTs between amoebae and their bacterial endosymbionts. Our study strongly supports the "melting pot" hypothesis and highlights the role of amoebae in shaping the Rickettsiales evolution. PMID- 29177482 TI - Lighting Van Leeuwenhoek's samples. AB - Possible techniques for lighting opaque samples while using Van Leeuwenhoek microscopes have been tested, and the results are presented in relation to published material. The design of the microscope causes the sample to be in shadow with any form of top lighting. It is therefore suggested that Van Leeuwenhoek's hinted 'particular method of observing' might refer to a different style of microscope as shown in the frontispiece of the sale catalogue for his microscopes, and available at that time for purchase from sellers of optical equipment.

AB - This study examined the age difference in the relationship between social capital in the form of cognitive (trust, family support) and structural aspects (social membership, activity frequency) and life satisfaction of older Chinese people in a rural area. Data were collected from 398 elders in the rural area of China by quota sampling. Hierarchical regression analysis was used to realize the objective. Trust and family support were significantly positively associated with life satisfaction, whereas social membership was strongly negatively associated with life satisfaction. Activity frequency did not show any significance in relationship with life satisfaction. Age difference existed in the associations of trust and activity frequency with life satisfaction. Age difference in the relationship of trust and activity frequency with life satisfaction of elderly Chinese people in the rural area did exist. It is recommended that the measure be refined and programs and services be provided according to the hierarchical needs of older adults in different age groups. PMID- 29177485 TI - Primary care access and foregone care: a survey of transgender adolescents and young adults. AB - Objective: To examine the issues of primary care access and foregone health care among transgender adolescents and young adults. Methods: This cross-sectional analysis of data from the Canadian Trans Youth Health Survey was conducted online during 2013-2014. Participants included 923 youth aged 14-25 (323 adolescents aged 14-18 and 600 young adults aged 19-25). Main outcome measures were self reported general and mental health status, comfort discussing transgender identity and health care needs with general practitioners, and types of and reasons for self-identified foregone health care. Results: Most youth reported poor/fair general and mental health status. Comfort with a family doctor was positively correlated with both general health (r(528) = 21, P < 0.001) and mental health (r(450) = 26, P < 0.001) status, as was having a doctor who was aware of one's transgender status. 47.2% (n = 219) of young adults reported foregoing needed health care. Among adolescents, levels of comfort with family doctor were negatively correlated with foregone mental health care in the previous 12 months (F3,166 = 3.829, P = 0.011), but not correlated with foregone physical health care (F3,165 = 0.506, P = 0.679). Reasons for missing needed care spanned the dimensions of health care access, ranging from cost barriers to previous negative experiences with health care providers, and concerns that a doctor would be uneducated about transgender people. Conclusion: General practitioners can play a key role in improving the health of transgender youth by demonstrating understanding of the health care needs of transgender youth and competence in gender-affirming care, and by ensuring that their practices are accessible to all transgender youth in need of care.

AB - Context: Glucagon-like peptide-1 (GLP-1) secretion from l-cells and postprandial inhibition of gastrointestinal motility. Objective: Investigate whether physiological plasma concentrations of GLP-1 inhibit human postprandial motility and determine mechanism of action of GLP-1 and analog ROSE-010 action. Design: Single-blind parallel study. Setting: University hospital laboratory. Participants: Healthy volunteers investigated with antroduodenal manometry. Human gastric and intestinal muscle strips. Interventions: Motility indices (MIs) obtained before and during GLP-1 or saline infusion. Plasma GLP-1 and glucagon like peptide-2 (GLP-2) measured by radioimmunoassay. Gastrointestinal muscle strips investigated for GLP-1- and ROSE-010-induced relaxation employing GLP-1 and GLP-2 and their receptor localization, and blockers exendin(9-39)amide, Lomega-nitro-monomethylarginine (L-NMMA), 2',5'-dideoxyadenosine (DDA), and tetrodotoxin (TTX) to reveal target mechanism of GLP-1 action. Main Outcome Measures: Postprandial gastrointestinal relaxation by GLP-1. Results: In humans, food intake increased MI to 6.4 +/- 0.3 (antrum), 5.7 +/- 0.4 (duodenum), and 5.9 +/- 0.2 (jejunum). GLP-1 administered intravenously raised plasma GLP-1, but not GLP-2. GLP-1 0.7 pmol/kg/min suppressed corresponding MI to 4.6 +/- 0.2, 4.7 +/- 0.4, and 5.0 +/- 0.2, whereas 1.2 pmol/kg/min suppressed MI to 5.4 +/- 0.2, 4.4 +/- 0.3, and 5.4 +/- 0.3 (P < 0.0001 to 0.005). In vitro, GLP-1 and ROSE-010 prevented contractions by bethanechol and electric field stimulation (P < 0.005 to 0.05). These effects were disinhibited by exendin(9-39)amide, L-NMMA, DDA, or TTX. GLP-1 and GLP-2 were localized to epithelial cells, GLP-1 also at myenteric neurons. GLP-1R and GLP-2R were localized at myenteric neurons but not muscle. Conclusions: GLP-1 and ROSE-010 inhibit postprandial gastrointestinal motility through GLP-1R at myenteric neurons, involving nitrergic and cyclic adenosine monophosphate-dependent mechanisms.

AB - External-beam radiation therapy is safe, effective and widely used to treat cancer. With 5-year cancer survival for adults above 70%, increasingly research is focusing on quantifying and reducing treatment-related morbidity. Reducing exposures to healthy tissues is one strategy, which can be accomplished with advanced-technology radiotherapies, such as intensity-modulated photon therapy and proton therapy. Both of these modalities provide good conformation of the therapeutic dose to the tumor volume, but they also deliver stray radiation to the whole body that increases the risk of radiogenic second cancers. To minimize these risks, one needs to create and compare candidate treatment plans that explicitly take into account these risks. Currently, clinical practice does not include routine calculation of stray radiation exposure and, consequently, the assessment of corresponding risks is difficult. In this article, we review recent progress toward stray dose algorithms that are suitable for large-scale clinical use. In particular, we emphasize the current state of physics-based dose algorithms for intensity-modulated photon radiotherapy and proton therapy. PMID- 29177489 TI - Disease-based antimicrobial stewardship: a review of active and passive approaches to patient management. AB - Although new antimicrobial stewardship programmes (ASPs) often begin by targeting the reduction of antimicrobial use, an increasing focus of ASPs is to improve the management of specific infectious diseases. Disease-based antimicrobial stewardship emphasizes improving patient outcomes by optimizing antimicrobial use and increasing compliance with performance measures. Directing efforts towards the comprehensive management of specific infections allows ASPs to promote the shift in healthcare towards improving quality, safety and patient outcome metrics for specific diseases. This review evaluates published active and passive disease based antimicrobial stewardship interventions and their impact on antimicrobial use and associated patient outcomes for patients with pneumonia, acute bacterial skin and skin structure infections, bloodstream infections, urinary tract infections, asymptomatic bacteriuria, Clostridium difficile infection and intra abdominal infections. Current literature suggests that disease-based antimicrobial stewardship effects on medical management and patient outcomes vary based on infectious disease syndrome, resource availability and intervention type. PMID- 29177490 TI - Analysis of the influences on plumage condition in laying hens: How suitable is a whole body plumage score as an outcome? AB - An important indicator of the health and behavior of laying hens is their plumage condition. Various scoring systems are used, and various risk factors for feather damage have been described. Often, a summarized score of different body parts is used to describe the overall condition of the plumage of a bird. However, it has not yet been assessed whether such a whole body plumage score is a suitable outcome variable when analyzing the risk factors for plumage deterioration. Data collected within a German project on farms keeping laying hens in aviaries were analyzed to investigate whether and the extent to which information is lost when summarizing the scores of the separate body parts. Two models were fitted using multiblock redundancy analysis, in which the first model included the whole body score as one outcome variable, while the second model included the scores of the individual body parts as multiple outcome variables. Although basically similar influences could be discovered with both models, the investigation of the individual body parts allowed for consideration of the influences on each body part separately and for the identification of additional influences. Furthermore, ambivalent influences (a factor differently associated with 2 different outcomes) could be detected with this approach, and possible dilutive effects were avoided. We conclude that influences might be underestimated or even missed when modeling their explanatory power for an overall score only. Therefore, multivariate methods that allow for the consideration of individual body parts are an interesting option when investigating influences on plumage condition. PMID- 29177491 TI - Scaling up improvements more quickly and effectively. AB - Faster and more widespread implementation could help more patients to benefit more quickly from known effective treatments. So could more effective implementation of better assessment methods, service delivery models, treatments and services. Implementation at scale and 'descaling' are ways for hospitals and health systems to respond to rising demands and costs. The paper proposes ways to provide leaders with the information that would help them to decide whether and how to scale up a proven improvement. We draw on our knowledge of the improvement and implementation literature on the subject and on our experience of scale up programs in Kaiser Permanente, in Swedish county health systems, and in international health. We describe a '3S' scale up infrastructure and other ingredients that appear necessary for successful widespread improvement, and list the resources that we have found useful for developing scale up programs. The paper aims to encourage more actionable research into scale up, and shows the opportunities for researchers to both advance implementation and improvement science and contribute to reducing suffering and costs in a more timely and effective way. PMID- 29177492 TI - An artist in surgery and a medical educator. PMID- 29177493 TI - Calretinin interneuron density in the caudate nucleus is lower in autism spectrum disorder. AB - Autism spectrum disorder is a debilitating condition with possible neurodevelopmental origins but unknown neuroanatomical correlates. Whereas investigators have paid much attention to the cerebral cortex, few studies have detailed the basal ganglia in autism. The caudate nucleus may be involved in the repetitive movements and limbic changes of autism. We used immunohistochemistry for calretinin and neuropeptide Y in 24 age- and gender-matched patients with autism spectrum disorder and control subjects ranging in age from 13 to 69 years. Patients with autism had a 35% lower density of calretinin+ interneurons in the caudate that was driven by loss of small calretinin+ neurons. This was not caused by altered size of the caudate, as its cross-sectional surface areas were similar between diagnostic groups. Controls exhibited an age-dependent increase in the density of medium and large calretinin+ neurons, whereas subjects with autism did not. Diagnostic groups did not differ regarding ionized calcium-binding adapter molecule 1+ immunoreactivity for microglia, suggesting chronic inflammation did not cause the decreased calretinin+ density. There was no statistically significant difference in the density of neuropeptide Y+ neurons between subjects with autism and controls. The decreased calretinin+ density may disrupt the excitation/inhibition balance in the caudate leading to dysfunctional corticostriatal circuits. The description of such changes in autism spectrum disorder may clarify pathomechanisms and thereby help identify targets for drug intervention and novel therapeutic strategies.

PMID- 29177494 TI - Domain-general subregions of the medial prefrontal cortex contribute to recovery of language after stroke. AB - We hypothesized that the recovery of speech production after left hemisphere stroke not only depends on the integrity of language-specialized brain systems, but also on 'domain-general' brain systems that have much broader functional roles. The presupplementary motor area/dorsal anterior cingulate forms part of the cingular-opercular network, which has a broad role in cognition and learning. Consequently, we have previously suggested that variability in the recovery of speech production after aphasic stroke may relate in part to differences in patients' abilities to engage this domain-general brain region. To test our hypothesis, 27 patients (aged 59 +/- 11 years) with a left hemisphere stroke performed behavioural assessments and event-related functional magnetic resonance imaging tasks at two time points; first in the early phase (~2 weeks) and then ~4 months after the ictus. The functional magnetic resonance imaging tasks were designed to differentiate between activation related to language production (sentential overt speech production-Speech task) and activation related to cognitive processing (non-verbal decision making). Simple rest and counting conditions were also included in the design. Task-evoked regional brain activations during the early and late phases were compared with a longitudinal measure of recovery of language production. In accordance with a role in cognitive processing, substantial activity was observed within the presupplementary motor area/dorsal anterior cingulate during the decision-making task. Critically, the level of activation within this region during speech production correlated positively with the longitudinal recovery of speech production across the two time points (as measured by the in-scanner performance in the Speech task). This relationship was observed for activation in both the early phase (r = 0.363, P = 0.03 one-tailed) and the late phase (r = 0.538, P = 0.004). Furthermore, presupplementary motor area/dorsal anterior cingulate activity was a predictor of both language recovery over time and language outcome at ~4 months, over and above that predicted by lesion volume, age and the initial language impairment (general linear model overall significant at P < 0.0001; ExpB 1.01, P = 0.02). The particularly prominent relationship of the presupplementary motor area/dorsal anterior cingulate region with recovery of language was confirmed in voxel-wise correlation analysis, conducted unconstrained for the whole brain volume. These results accord with the hypothesis that the functionality of the presupplementary motor area/dorsal anterior cingulate contributes to language recovery after stroke. Given that this brain region is often spared in aphasic stroke, we propose that it is a sensible target for future research into rehabilitative treatments. More broadly, baseline assessment of domain-general systems could help provide a better prediction of language recovery.

AB - Objective: The purpose of this study was to evaluate the analgesic effect of a prilocaine + bupivacaine combination in patients undergoing periprostatic nerve block (PNB) by comparing its effects with those of prilocaine alone. Design: Single center, single-blind, prospective descriptive study. Subjects: Four hundred patients with transrectal prostate biopsy pain. Methods: The patients in this prospective, randomized controlled study were divided into two groups. The first group received prilocaine during PNB (Group 1), whereas the second received a prilocaine + bupivacaine combination (Group 2). Results: The mean visual analog scale (VAS) scores immediately after biopsy were 2.52 +/- 0.7 and 2.53 +/- 0.9, respectively (P = 0.35). VAS values were significantly lower in Group 2 at one and six hours following the procedure. The most painful part of the biopsy according to many patients was the probe insertion. Conclusions: The prilocaine + bupivacaine combination is an effective analgesic method during prostate biopsies and for one and six hours after prostate biopsy. PMID- 29177502 TI - Prognostic value of lymph node count on survival in pathologically node-negative oesophageal squamous cell cancer. AB - OBJECTIVES: This study aims to determine whether lymph node (LN) count is an independent predictor of survival in patients with pathologically node-negative (pN0) oesophageal squamous cell carcinoma (OSCC). METHODS: Retrospective analysis was performed on 194 pN0 OSCC patients undergoing radical oesophagectomy between January 2004 and December 2008. The association between the LN count and survival was assessed using the Cox proportional hazard model. The optimal LN count cut off values were determined using the X-tile program. RESULTS: A total of 10 and 29 nodes were used as the cut-off values determined by X-tile program. Subsequently, all patients were divided into the high-, middle- and low-risk subsets in terms of 5-year overall survival rates, which were 36.7%, 56.9% and 81.8%, respectively (P < 0.001). LN count was also validated as an independent prognostic factor in multivariate Cox analysis (P < 0.001; hazard ratio 0.45; 95% confidence interval 0.29-0.69). Further analysis showed that patients with 14 or more LN count showed a reduced death from OSCC compared with those with less than 14 LN count (P = 0.002, 5-year overall survival 66% vs 46.5%). CONCLUSIONS: LN count exhibits prognostic significance in pN0 OSCC. In addition, the minimum number of LNs that should be removed in pN0 OSCC is probably 14. PMID- 29177503 TI - Mice with either diminished or elevated levels of anti-Mullerian hormone have decreased litter sizes. AB - Anti-Mullerian hormone (AMH) is both a gonadal hormone and a putative paracrine regulator of neurons, the uterus, and the placenta. A mouse line with neuronal expression of AMH (Thy1.2-AMH) was generated to examine the role of paracrine AMH in the brain. The mice had normal behavior, but unexpectantly AMH was present in the circulation of the transgenic mice. Thy1.2-AMHTg/0 studs sired pups with a normal frequency, when mated with wild-type dams. In stark contrast, Thy1.2 AMHTg/0 dams rarely gave birth, with evidence of spontaneous midgestational abortion. This leads to the hypothesis that AMH influences the capacity of dams to carry concepti to term. This hypothesis was tested by mating AMH-deficient (Amh-/-), Thy1.2-AMHTg/0, and wild-type dams when 49-, 80-, and 111 days old, using proven wild-type studs. The litter sizes from the first two matings and the number of fetuses present on the 10th day of gestation of the third mating were recorded. Thy1.2-AMHTg/0 dams carried near normal numbers of midterm fetuses, but typically produced no pups, indicating that extensive late resorption of fetuses was occurring. Amh-/- dams exhibited a lesser reduction in litter size than the Thy1.2-AMHTg/0 dams, with no evidence of enhanced loss of fetuses. In conclusion, this study provides the first evidence that high AMH levels can cause a miscarriage phenotype and that the absence of AMH affects reproductive output. PMID- 29177504 TI - Pathogenomic Analysis of Wheat Yellow Rust Lineages Detects Seasonal Variation and Host Specificity. AB - Recent disease outbreaks caused by (re-)emerging plant pathogens have been associated with expansions in pathogen geographic distribution and increased virulence. For example, in the past two decades' wheat yellow (stripe) rust, Puccinia striiformis f. sp. tritici, has seen the emergence of new races that are adapted to warmer temperatures, have expanded virulence profiles, and are more aggressive than previous races, leading to wide-scale epidemics. Here, we used field-based genotyping to generate high-resolution data on P. striiformis genetics and carried out global population analysis. We also undertook comparative analysis of the 2014 and 2013 UK populations and assessed the temporal dynamics and host specificity of distinct pathogen genotypes. Our analysis revealed that P. striiformis lineages recently detected in Europe are extremely diverse and in fact similar to globally dispersed populations. In addition, we identified a considerable shift in the UK P. striiformis population structure including the first identification of one infamous race known as Kranich. Next, by establishing the genotype of both the pathogen and host within a single infected field sample, we uncovered evidence for varietal specificity for genetic groups of P. striiformis. Finally, we found potential seasonal specificity for certain genotypes of the pathogen with several lineages identified only in samples collected in late spring and into the summer, whereas one lineage was identified throughout the wheat growing season. Our discovery of which wheat varieties are susceptible to which specific P. striiformis isolates, and when those isolates are prevalent throughout the year, represents a powerful tool for disease management.

AB - H/ACA ribonucleoproteins (H/ACA RNPs) are responsible for introducing many pseudouridines into RNAs, but are also involved in other cellular functions. Utilizing a purified and reconstituted yeast H/ACA RNP system that is active in pseudouridine formation under physiological conditions, we describe here the quantitative characterization of H/ACA RNP formation and function. This analysis reveals a surprisingly tight interaction of H/ACA guide RNA with the Cbf5p-Nop10p Gar1p trimeric protein complex whereas Nhp2p binds comparably weakly to H/ACA guide RNA. Substrate RNA is bound to H/ACA RNPs with nanomolar affinity which correlates with the GC content in the guide-substrate RNA base pairing. Both Nhp2p and the conserved Box ACA element in guide RNA are required for efficient pseudouridine formation, but not for guide RNA or substrate RNA binding. These results suggest that Nhp2p and the Box ACA motif indirectly facilitate loading of the substrate RNA in the catalytic site of Cbf5p by correctly positioning the upper and lower parts of the H/ACA guide RNA on the H/ACA proteins. In summary, this study provides detailed insight into the molecular mechanism of H/ACA RNPs. PMID- 29177506 TI - LRRK2 phosphorylates membrane-bound Rabs and is activated by GTP-bound Rab7L1 to promote recruitment to the trans-Golgi network. AB - Human genetic studies implicate LRRK2 and RAB7L1 in susceptibility to Parkinson disease (PD). These two genes function in the same pathway, as knockout of Rab7L1 results in phenotypes similar to LRRK2 knockout, and studies in cells and model organisms demonstrate LRRK2 and Rab7L1 interact in the endolysosomal system. Recently, a subset of Rab proteins have been identified as LRRK2 kinase substrates. Herein, we find that Rab8, Rab10, and Rab7L1 must be membrane and GTP bound for LRRK2 phosphorylation. LRRK2 mutations that cause PD including R1441C, Y1699C, and G2019S all increase LRRK2 phosphorylation of Rab7L1 four-fold over wild-type LRRK2 in cells, resulting in the phosphorylation of nearly one-third the available Rab7L1 protein in cells. In contrast, the most common pathogenic LRRK2 mutation, G2019S, does not upregulate LRRK2-mediated phosphorylation of Rab8 or Rab10. LRRK2 interaction with membrane and GTP-bound Rab7L1, but not Rab8 or Rab10, results in the activation of LRRK2 autophosphorylation at the serine 1292 position, required for LRRK2 toxicity. Further, Rab7L1 controls the proportion of LRRK2 that is membrane-associated, and LRRK2 mutations enhance Rab7L1-mediated recruitment of LRRK2 to the trans-Golgi network. Interaction studies with the Rab8 and Rab10 GTPase-activating protein TBC1D4/AS160 demonstrate that LRRK2 phosphorylation may block membrane and GTP-bound Rab protein interaction with effectors. These results suggest reciprocal regulation between LRRK2 and Rab protein substrates, where Rab7L1-mediated upregulation of LRRK2 kinase activity results in the stabilization of membrane and GTP-bound Rab proteins that may be unable to interact with Rab effector proteins.

AB - In January 2017, the Lung Cancer Surgical Study Group of the Japan Clinical Oncology Group commenced a randomized Phase III trial to confirm the clinical benefit of lobe-specific nodal dissection for clinical Stage I-II non-small cell lung cancer. The primary endpoint is overall survival, and the main objective is to confirm the non-inferiority of lobe-specific in comparison to systematic nodal dissection with regard to lobectomy. The secondary endpoints are relapse-free survival, %local recurrence, %regional lymph node recurrence, operation time, blood loss, length of hospitalization, duration of chest tube placement and adverse events. A total of 1700 patients will be accrued from 44 Japanese institutions within 5 years. This study is the first and large prospective trial to evaluate whether the difference in the area of nodal dissection affects the overall survival of patients with relatively early-stage non-small cell lung cancer. This trial has been registered in the UMIN Clinical Trials Registry as UMIN000025530. PMID- 29177508 TI - MVP: a microbe-phage interaction database. AB - Phages invade microbes, accomplish host lysis and are of vital importance in shaping the community structure of environmental microbiota. More importantly, most phages have very specific hosts; they are thus ideal tools to manipulate environmental microbiota at species-resolution. The main purpose of MVP (Microbe Versus Phage) is to provide a comprehensive catalog of phage-microbe interactions and assist users to select phage(s) that can target (and potentially to manipulate) specific microbes of interest. We first collected 50 782 viral sequences from various sources and clustered them into 33 097 unique viral clusters based on sequence similarity. We then identified 26 572 interactions between 18 608 viral clusters and 9245 prokaryotes (i.e. bacteria and archaea); we established these interactions based on 30 321 evidence entries that we collected from published datasets, public databases and re-analysis of genomic and metagenomic sequences. Based on these interactions, we calculated the host range for each of the phage clusters and accordingly grouped them into subgroups such as 'species-', 'genus-' and 'family-' specific phage clusters. MVP is equipped with a modern, responsive and intuitive interface, and is freely available at: http://mvp.medgenius.info.

In countries with the heavy burden of tuberculosis, a high index of suspicion is needed for early diagnosis of its close mimics like disseminated cryptococcosis. PMID- 29177509 TI - Repetitive behaviors in autism are linked to imbalance of corticostriatal connectivity: a functional connectivity MRI study. AB - The neural underpinnings of repetitive behaviors (RBs) in autism spectrum disorders (ASDs), ranging from cognitive to motor characteristics, remain unknown. We assessed RB symptomatology in 50 ASD and 52 typically developing (TD) children and adolescents (ages 8-17 years), examining intrinsic functional connectivity (iFC) of corticostriatal circuitry, which is important for reward based learning and integration of emotional, cognitive and motor processing, and considered impaired in ASDs. Connectivity analyses were performed for three functionally distinct striatal seeds (limbic, frontoparietal and motor). Functional connectivity with cortical regions of interest was assessed for corticostriatal circuit connectivity indices and ratios, testing the balance of connectivity between circuits. Results showed corticostriatal overconnectivity of limbic and frontoparietal seeds, but underconnectivity of motor seeds. Correlations with RBs were found for connectivity between the striatal motor seeds and cortical motor clusters from the whole-brain analysis, and for frontoparietal/limbic and motor/limbic connectivity ratios. Division of ASD participants into high (n = 17) and low RB subgroups (n = 19) showed reduced frontoparietal/limbic and motor/limbic circuit ratios for high RB compared to low RB and TD groups in the right hemisphere. Results suggest an association between RBs and an imbalance of corticostriatal iFC in ASD, being increased for limbic, but reduced for frontoparietal and motor circuits.

PMID- 29177512 TI - "The Lesser of Two Evils" Versus "Medicines not Smarties": Constructing Antipsychotics in Dementia. AB - Background and Objectives: Because antipsychotics are associated with an increased risk of morbidity and mortality, they should only be prescribed in dementia in limited circumstances. But antipsychotics are prescribed to a large proportion of residents in formal care settings despite guidance and warnings to the contrary, justifying a study into how professionals define and in turn create realities about antipsychotic usage in dementia. Research Design and Methods: Twenty-eight professionals with a role in the care and management of patients with dementia in care homes were recruited and interviewed in this qualitative study. A gap in the literature about the social construction of antipsychotics in dementia prompted the use of critical discourse analysis methodology. Results: Antipsychotics were portrayed in 2 distinct ways; as "the lesser of two evils' they were conceptualized as the less harmful or unpleasant of 2 bad choices and as "medicines not Smarties" (a brand of sweets/candy) they were conceptualized as prescribed too frequently and indiscriminately. The first resource could be used to defend the prescribing of antipsychotics and uphold the prescribers' privilege to do so whereas the second enabled the speaker to reject their own wilful involvement in overprescribing. Discussion and Implications: When prescribers draw on "the lesser of two evils" paradigm to sanction the overprescribing of antipsychotics, implicit assumptions about these medications as being the best of bad choices should be recognized and challenged. Future studies should target specific normative beliefs about antipsychotic prescribing consequences, to change the lexicon of common knowledge which perpetuates bad practice. PMID- 29177513 TI - Multiple Regulatory Modules Are Required for Scale-to-Feather Conversion. AB - The origin of feathers is an important question in Evo-Devo studies, with the eventual evolution of vaned feathers which are aerodynamic, allowing feathered dinosaurs and early birds to fly and venture into new ecological niches. Studying how feathers and scales are developmentally specified provides insight into how a new organ may evolve. We identified feather-associated genes using genomic analyses. The candidate genes were tested by expressing them in chicken and alligator scale forming regions. Ectopic expression of these genes induced intermediate morphotypes between scales and feathers which revealed several major morphogenetic events along this path: Localized growth zone formation, follicle invagination, epithelial branching, feather keratin differentiation, and dermal papilla formation. In addition to molecules known to induce feathers on scales (retinoic acid, beta-catenin), we identified novel scale-feather converters (Sox2, Zic1, Grem1, Spry2, Sox18) which induce one or more regulatory modules guiding these morphogenetic events. Some morphotypes resemble filamentous appendages found in feathered dinosaur fossils, whereas others exhibit characteristics of modern avian feathers. We propose these morpho-regulatory modules were used to diversify archosaur scales and to initiate feather evolution. The regulatory combination and hierarchical integration may have led to the formation of extant feather forms. Our study highlights the importance of integrating discoveries between developmental biology and paleontology. PMID- 29177516 TI - NEUTRON WORKPLACE SPECTROMETRY (ENERGY AND DIRECTION) USING TL DETECTORS: FIRST APPROACH AND RESPONSE FUNCTIONS. AB - The response of albedo dosemeters depends on the energy and angle of the incident neutron radiation. For their use as personal dosemeters, a field-calibration factor has to be applied. The presently used single sphere method for field calibration can be extended and optimised by putting five albedo dosemeters on the surface of a polyethylene sphere and two TL cards in the centre. To investigate the potential of this extension, reference measurements and Monte Carlo calculations were performed and the fluence response of the detectors at different positions on and within the sphere was determined. Calculated response functions demonstrate that information on the energy and directional distribution of neutron fluence can be extracted with this simple set-up for unknown neutron fields. PMID- 29177515 TI - Clinical Aspects of SDHA-Related Pheochromocytoma and Paraganglioma: A Nationwide Study. AB - Context: Paraganglioma (PGL) has the highest degree of heritability among human neoplasms. Current clinical understanding of germline SDHA mutation carriers is limited. Objective: To estimate the contribution of SDHA mutations in PGL and to assess clinical manifestations and age-related penetrance. Design: Nationwide retrospective cohort study. Setting: Tertiary referral centers in the Netherlands (multicenter). Patients: Germline SDHA analysis was performed in 393 patients with genetically unexplained PGL. Subsequently, 30 index SDHA mutation carriers and 56 nonindex carriers were studied. Main Outcome Measures: SDHA mutation detection yield, clinical manifestations, and SDHA-related disease penetrance. Results: Pathogenic germline SDHA variants were identified in 30 of the 393 referred patients with PGL (7.6%), who had head and neck PGL (21 of 174 [12%]), pheochromocytoma (4 of 191 [2%]), or sympathetic PGL (5 of 28 [18%]). The median age at diagnosis was 43 years (range, 17 to 81 years) in index SDHA mutation carriers compared with 52 years (range, 7 to 90 years) in nonmutation carriers (P = 0.002). The estimated penetrance of any SDHA-related manifestation was 10% at age 70 years (95% confidence interval, 0% to 21%) in nonindex mutation carriers. Conclusion: Germline SDHA mutations are relatively common (7.6%) in patients with genetically unexplained PGL. Most index patients presented with apparently sporadic PGL. In this SDHA series, the largest assembled so far, we found the lowest penetrance of all major PGL predisposition genes. This suggests that recommendations for genetic counseling of at-risk relatives and stringency of surveillance for SDHA mutation carriers might need to be reassessed. PMID- 29177514 TI - Transcriptome analysis of Pinus halepensis under drought stress and during recovery. AB - Forest trees use various strategies to cope with drought stress and these strategies involve complex molecular mechanisms. Pinus halepensis Miller (Aleppo pine) is found throughout the Mediterranean basin and is one of the most drought tolerant pine species. In order to decipher the molecular mechanisms that P. halepensis uses to withstand drought, we performed large-scale physiological and transcriptome analyses. We selected a mature tree from a semi-arid area with suboptimal growth conditions for clonal propagation through cuttings. We then used a high-throughput experimental system to continuously monitor whole-plant transpiration rates, stomatal conductance and the vapor pressure deficit. The transcriptomes of plants were examined at six physiological stages: pre-stomatal response, partial stomatal closure, minimum transpiration, post-irrigation, partial recovery and full recovery. At each stage, data from plants exposed to the drought treatment were compared with data collected from well-irrigated control plants. A drought-stressed P. halepensis transcriptome was created using paired-end RNA-seq. In total, ~6000 differentially expressed, non-redundant transcripts were identified between drought-treated and control trees. Cluster analysis has revealed stress-induced down-regulation of transcripts related to photosynthesis, reactive oxygen species (ROS)-scavenging through the ascorbic acid (AsA)-glutathione cycle, fatty acid and cell wall biosynthesis, stomatal activity, and the biosynthesis of flavonoids and terpenoids. Up-regulated processes included chlorophyll degradation, ROS-scavenging through AsA independent thiol-mediated pathways, abscisic acid response and accumulation of heat shock proteins, thaumatin and exordium. Recovery from drought induced strong transcription of retrotransposons, especially the retrovirus-related transposon Tnt1-94. The drought-related transcriptome illustrates this species' dynamic response to drought and recovery and unravels novel mechanisms. PMID- 29177517 TI - My Brother Patrick's Dying Wish.

AB - Post-acute care for older adults often involves transfer to a skilled nursing facility (SNF) following hospital discharge. This transition is often poorly coordinated and leaves older adults at risk for poor health outcomes, but new payment models offer opportunities to align improved care practices with payments. There is a dearth of evidence regarding the role of nursing and its potential to improve hospital to SNF care transitions. Ninety-nine semi structured interviews were conducted with clinicians, patients, and caregivers from three hospitals and three SNFs. Results indicate a sharp contrast in the roles of hospital nurses-who are often silent partners in post-acute care decision making-and SNF nurses, who take a primary role as managing "the fit" for patients transitioning to a SNF. Nurses are uniquely positioned to make needed changes to culture to adapt to new payment models and improve patient outcomes. [Journal of Gerontological Nursing, 43(12), 11-20.].

AB - BACKGROUND: A paucity of literature exists on use of the affective domain to improve adherence to pressure injury prevention. The purpose of this study was to assess the use of emphasizing the cognitive domain versus education based on combination of the affective and cognitive domains focusing on medical-surgical nurses' behavioral intent to use evidence-based practices to prevent pressure injury. METHOD: A cluster randomized, controlled design was used to compare differences between groups. Medical-surgical nurses in units with low performance in pressure ulcer prevention were studied. A total of 77 nurses participated. This study employed the theory of planned behavior. RESULTS: Attitudes toward pressure ulcer predicted behavioral intent. Nurses who experienced the affective domain education showed improvements over the control group for attitude and perceived behavioral control. CONCLUSION: Affective domain interventions have the potential to favorably impact nurses in valuing pressure ulcer prevention, despite any barriers. J Contin Educ Nurs. 2017;48(12):543-551.

AB - BACKGROUND: This study evaluated Turkish oncology nurses' knowledge and educational needs regarding genetics of hereditary breast and ovarian cancers. METHOD: An online survey was used to collect data from 104 Turkish oncology nurses. RESULTS: The mean level of knowledge in oncology genetics was 6.74 +/- 3.85. The majority of nurses (78.7%) were aware of the fact that family history of ovarian or breast cancer is an important risk factor for ovarian or breast cancer; however, a much smaller percentage (25.5%) understood that BRCA1 mutations in women can be transferred by the father. The majority of the nurses (59.6%) were willing to take continuing education in cancer genetics. CONCLUSION: Turkish oncology nurses have a moderate level of knowledge in cancer genetics. Therefore, educators should develop targeted educational activities in genetics as a part of continuing education programs to enhance nursing practice in cancer care.

AB - Baculoviruses are large DNA virus of insects principally employed in recombinant protein expression. Its ability to form occlusion bodies (OBs), which are composed mainly of polyhedrin protein (POLH), makes them biotechnologically attractive, as these crystals (polyhedra) can incorporate foreign peptides and can be easily isolated. On the other hand, peptide microarrays allow rapid and inexpensive high-throughput serological screening of new candidates to be incorporated to OBs. To integrate these 2 biotechnological approaches, we worked on Babesia bovis, one of the causative agents of bovine babesiosis. Current molecular diagnosis of infection with B. bovis includes enzyme-linked immunosorbent assay (ELISA) techniques, which use merozoite lysate obtained from infected bovine erythrocytes. However, it is important to produce recombinant antigens that replace the use of crude antigens. Here, we describe a new biotechnological platform for the design of indirect ELISAs based on 5 antigenic peptides of 15 amino acid residues of B. bovis (ApBb), selected from a peptide microarray and expressed as a fusion to POLH. An Sf9POLHE44G packaging cell line infected with recombinant baculoviruses carrying POLH-ApBb fusions yielded higher levels of chimeric polyhedra, highlighting the advantage of a trans-contribution of a mutant copy of polyhedrin. Finally, the use of dissolved recombinant polyhedra as antigens was successful in an ELISA assay, as B. bovis-positive sera recognized the fusion POLH-ApBb. Thus, the use of this platform resulted in a promising alternative for molecular diagnosis of relevant infectious diseases. PMID- 29177534 TI - Structural variations in wheat HKT1;5 underpin differences in Na+ transport capacity. AB - An important trait associated with the salt tolerance of wheat is the exclusion of sodium ions (Na+) from the shoot. We have previously shown that the sodium transporters TmHKT1;5-A and TaHKT1;5-D, from Triticum monoccocum (Tm) and Triticum aestivum (Ta), are encoded by genes underlying the major shoot Na+ exclusion loci Nax1 and Kna1, respectively. Here, using heterologous expression, we show that the affinity (K m) for the Na+ transport of TmHKT1;5-A, at 2.66 mM, is higher than that of TaHKT1;5-D at 7.50 mM. Through 3D structural modelling, we identify residues D471/a gap and D474/G473 that contribute to this property. We identify four additional mutations in amino acid residues that inhibit the transport activity of TmHKT1;5-A, which are predicted to be the result of an occlusion of the pore. We propose that the underlying transport properties of TmHKT1;5-A and TaHKT1;5-D contribute to their unique ability to improve Na+ exclusion in wheat that leads to an improved salinity tolerance in the field. PMID- 29177535 TI - Genome-wide association study of stem rust resistance in a world collection of cultivated barley. AB - KEY MESSAGE: QTL conferring a 14-40% reduction in adult plant stem rust severity to multiple races of Pgt were found on chromosome 5H and will be useful in barley breeding. Stem rust, caused by Puccinia graminis f. sp. tritici (Pgt) is an important disease of barley. The resistance gene Rpg1 has protected the crop against stem rust losses for over 70 years in North America, but is not effective against the African Pgt race TTKSK (and its variants) nor the domestic race QCCJB. To identify resistance to these Rpg1-virulent races, the Barley iCore Collection, held by the United States Department of Agriculture-Agricultural Research Service National Small Grains Collection was evaluated for adult plant resistance (APR) and seedling resistance to race TTKSK and APR to race QCCJB and the Pgt TTKSK composite of races TTKSK, TTKST, TTKTK, and TTKTT. Using a genome wide association study approach based on 6224 single nucleotide polymorphic markers, seven significant loci for stem rust resistance were identified on chromosomes 1H, 2H, 3H, and 5H. The most significant markers detected were 11_11355 and SCRI_RS_177017 at 71-75 cM on chromosome 5H, conferring APR to QCCJB and TTKSK composite. Significant markers were also detected for TTKSK seedling resistance on chromosome 5H. All markers detected on 5H were independent of the rpg4/Rpg5 complex at 152-168 cM. This study verified the importance of the 11_11355 locus in conferring APR to races QCCJB and TTKSK and suggests that it may be effective against other races in the Ug99 lineage.

AB - PURPOSE: To evaluate whether exhaled nitric oxide measurement can facilitate in the assessment of chronic cough patients based on their airway inflammatory phenotype. METHODS: We have studied consecutive patients attending a specialist cough clinic. 30 patients with high FeNO (> 30 ppb) and 20 patients with low FeNO (< 20 ppb) were recruited. RESULTS: There was a significant correlation between FeNO, B-Eos and sputum eosinophil count (p < 0.001). The number of recorded coughs in 24 h and HARQ scores were significantly (p < 0.05) higher in patients with a low FeNO. In contrast to the high FeNO group (48%), the greater proportion of these patients were women (90%). LCQ scores were worse in the low FeNO group but it was not significant. CONCLUSION: A strong relationship between FeNO, blood eosinophils and sputum eosinophils confirming phenotypic identity was observed. Whether the observed gender disparity accounts for the different cough frequency characteristics is unknown. PMID- 29177540 TI - The distance of the gluteal nerve in relation to anatomical landmarks: an anatomic study. AB - INTRODUCTION: Gluteal insufficiency is of concern with lateral approaches to total hip arthroplasty. Damage to the branches of the superior gluteal nerve may cause degeneration of the innervated muscles. The direct anterior approach exploits the intermuscular and internerval interval between tensor fasciae latae laterally and sartorius and rectus femoris muscle medially. In this study, the distance of the superior gluteal nerve in relation to anatomical landmarks was determined. MATERIALS AND METHODS: Two experienced surgeons implanted trial components in 15 alcohol glycerol fixed cadavers with 30 hips. The trials were removed, and the main branch of the superior gluteal nerve and muscular branches of the nerve were exposed from lateral. RESULTS: No visual damage to the main nerve branches and the location of the nerve in relation to the greater trochanter were noted by an experienced surgeon. The superior gluteal nerve and its muscular branches crossed the muscular interval between the gluteus medius and tensor fasciae latae muscles at a mean distance of 39 mm from the tip of the greater trochanter. CONCLUSIONS: The direct anterior approach for total hip arthroplasty minimizes the risk of injuring the superior gluteal nerve, which may result in a gluteal insufficiency. Special care should be paid on avoiding overstretching the tensor fasciae latea muscle using minimum force on retractors during surgery and by taking care of the entrance point of the superior gluteal nerve to the tensor fasciae latae.

The purpose of this study is to assess whether combined CT-based and image-free navigation systems replicate accurately the rotational alignment of tibial component that was preoperatively planned on CT, compared with the conventional method. MATERIALS AND METHODS: We compared the number of outliers for rotational alignment of the tibial component using combined CT-based and image-free navigation systems (navigated group) with those of conventional method (conventional group). Seventy-two TKAs were performed between May 2012 and December 2014. In the navigated group, the anteroposterior axis was prepared using CT-based navigation system and the tibial component was positioned under control of the navigation. In the conventional group, the tibial component was placed with reference to the Akagi line that was determined visually. Fisher's exact probability test was performed to evaluate the results. RESULTS: There was a significant difference between the two groups with regard to the number of outliers: 3 outliers in the navigated group compared with 12 outliers in the conventional group (P < 0.01). CONCLUSIONS: We concluded that combined CT-based and image-free navigation systems decreased the number of rotational outliers of tibial component, and was helpful for the replication of the accurate rotational alignment of the tibial component that was preoperatively planned. PMID- 29177542 TI - Adjustable transobturator sling for the treatment of primary stress urinary incontinence. AB - INTRODUCTION AND HYPOTHESIS: The purpose of the study was to evaluate the rate of postoperative voiding dysfunction after the insertion of an adjustable transobturator sling for the treatment of primary stress urinary incontinence (SUI). The secondary aim was to assess the objective and subjective cure rates and the impact of the surgery on quality of life. METHODS: This prospective study included 171 patients with primary SUI who underwent insertion of an adjustable transobturator tape. A postoperative tension adjustment algorithm that included a cough stress test (CST), uroflowmetry and postvoid residual volume (PVR) measurement was applied in all patients the day after surgery. The baseline and control postoperative evaluations included vaginal examination, CST, Q-tip test, uroflowmetry and PVR measurement, 1-h pad test and administration questionnaires (UDI-6, IIQ-7, PISQ-12, ICIQ-SF). RESULTS: The day after surgery 65 patients (38.0%) required tape tension adjustment: an increase in tension in 53 patients (31.0%) and a decrease in 12 (7.0%). Continence was achieved in all patients. No patients showed voiding dysfunction after adjustment. Follow-up data for 12 months were available in 157 patients (91.8%). The objective and subjective cure rates were 96.2% and 97.5%, respectively. There was no statistically significant decrease in Qmax (p = 0.899) or increase in PVR (p = 0.187). According to the questionnaires scores, quality of life was improved in all patients. CONCLUSION: The adjustable transobturator sling minimizes the risk of postoperative voiding dysfunction and allows high objective and subjective cure rates to be achieved in patients with primary SUI. The technique also improves the patient's quality of life. PMID- 29177543 TI - Comment on "Detrusor pressures in urodynamic studies during voiding in women". PMID- 29177544 TI - Are the same tapes really the same? Ultrasound study of laser-cut and mechanically cut TVT-O post-operative behavior. AB - INTRODUCTION AND HYPOTHESIS: TVT-O production has been modified to laser cutting from mechanical cutting. We compared the behavior of laser and mechanically cut tension-free vaginal tape-obturator (TVT-O) using ultrasound at various time points after surgery. METHODS: This is a retrospective analysis of clinical and ultrasound data from two previously reported randomized controlled trials with TVT-O. Behavior of mechanically cut TVT-O implanted in January 2007 to November 2009 and laser-cut TVT-O implanted in May 2010 to May 2012 was assessed by ultrasound at day 1, the 2nd week, the 3rd month, and the 1st and 2nd years post operatively. Bladder neck and tape margins positions were described by coordinates in the orthogonal system calculated from polar coordinates. Tape mobility was measured as a change in the upper and lower tape margin position from rest to maximal Valsalva. Comparison of 2-year subjective and objective surgery outcomes was also performed. RESULTS: In total, 68 mechanically cut and 50 laser-cut TVT-Os were implanted. Follow-up data were available from 49 and 45 women respectively. No differences in any baseline characteristics or bladder neck mobility were observed. Significantly lower tape mobility was observed on day 1 and week 2 after mechanically cut TVT-O, although subsequent mobility was comparable to laser-cut TVT-O. The subjective and objective surgery outcomes were comparable. CONCLUSIONS: Although without clinical significance, early postoperative behavior of the mechanically cut and laser-cut TVT-O tapes differs. The less stiff, mechanically-cut TVT-O loosens within 2 weeks of implantation, whereas the stiffer, laser-cut TVT-O keeps its tension. PMID- 29177545 TI - Porcine teschovirus 2 induces an incomplete autophagic response in PK-15 cells. AB - Autophagy is a homeostatic process that has been shown to be vital in the innate immune defense against pathogens. However, little is known about the regulatory role of autophagy in porcine teschovirus 2 (PTV-2) replication. In this study, we found that PTV-2 infection induces a strong increase in GFP-LC3 punctae and endogenous LC3 lipidation. However, PTV-2 infection did not enhance autophagic protein degradation. When cellular autophagy was pharmacologically inhibited by wortmannin or 3-methyladenine, PTV-2 replication increased. The increase in virus yield via autophagy inhibition was further confirmed by silencing atg5, which is required for autophagy. Furthermore, PTV-2 replication was suppressed when autophagy was activated by rapamycin. Together, the results suggest that PTV-2 infection activates incomplete autophagy and that autophagy then inhibits further PTV-2 replication.

PMID- 29177547 TI - Genetic and clinical characteristics of hereditary transthyretin amyloidosis in endemic and non-endemic areas: experience from a single-referral center in Japan. AB - Hereditary transthyretin (ATTR) amyloidosis is a life-threatening, autosomal dominant, systemic amyloidosis caused by mutant transthyretin. In addition to ATTRV30M in endemic and non-endemic areas, more than 140 non-V30M mutations occur worldwide. The aim of this study was to analyze the clinical characteristics and genetic frequencies of hereditary ATTR amyloidosis. Diagnostic results and clinical manifestations of hereditary ATTR amyloidosis from April 1, 2012, to March 31, 2017, at Amyloidosis Medical Practice Center, Kumamoto University Hospital were analyzed. One hundred and four patients received a diagnosis of symptomatic hereditary ATTR amyloidosis. The following mutations of the TTR gene and their percentages were found: V30M in endemic areas, 10.6%; V30M in non endemic areas, 51.0%; and non-V30M, 38.5%. The ages at onset of patients with ATTRV30M amyloidosis in non-endemic areas (66.6 +/- 8.7 years) and those with non V30M ATTR amyloidosis (55.8 +/- 13.6 years) were significantly higher than those with ATTRV30M amyloidosis in endemic areas (37.0 +/- 12.6 years). Of patients with ATTRV30M amyloidosis in endemic and non-endemic areas, and non-V30M ATTR amyloidosis, 63.6, 66.0, and 27.5% initially presented with polyneuropathy, respectively. Of patients with ATTRV30M amyloidosis in endemic areas, 81.8% had a family history of this disease. However, a significantly smaller percentage of patients with ATTRV30M amyloidosis (30.0%) in non-endemic areas and non-V30M ATTR amyloidosis (34.0%) had a family history. Patients with ATTRV30M amyloidosis in non-endemic areas and patients with non-V30M ATTR amyloidosis occurred more frequently than previously believed, and their clinical manifestations were diverse. PMID- 29177548 TI - Pediatric Bickerstaff brainstem encephalitis: a systematic review of literature and case series. AB - OBJECTIVE: To characterize the phenotype of pediatric Bickerstaff's brainstem encephalitis (BBE) and evaluate prognostic features in the clinical course, diagnostic studies, and treatment exposures. METHODS: We systematically reviewed PubMed, Web of Science, and SCOPUS databases as well as medical records at the Lucile Packard Children's Hospital to identify cases of pediatric BBE. Inclusion required all of the following criteria: age <= 20 years, presence of somnolence or alterations in mental status at the time of presentation or developed within 7 days of presentation, ataxia, and ophthalmoplegia. RESULTS: We reviewed 682 manuscripts, identifying a total of 47 pediatric BBE cases. We also describe five previously unreported cases. The phenotype of these pediatric patients was similar to previously published literature. Sixty-eight percent of patients demonstrated positive anti-GQ1b antibody titers, yet the presence of these antibodies was not associated with longer times to recovery. Patients with neuroimaging abnormalities featured a longer median time to recovery, but this was not statistically significant (p = 0.124). Overall, patients treated with any form of immunotherapy (intravenous immunoglobulin, steroids, or plasmapheresis) demonstrated shorter median time to resolution of symptoms compared to supportive therapy, although this trend was not statistically significant (p = 0.277). Post hoc t tests revealed a trend towards use of immunotherapy against supportive care alone (p = 0.174). CONCLUSION: Our study identified clinical, radiologic, and treatment features that may hold prognostic value for children with BBE. The role of immunotherapy remains under investigation but may prove of utility with further, randomized controlled studies in this rare disease. PMID- 29177549 TI - Different infarction patterns in patients with aortic atheroma compared to those with cardioembolism or large artery atherosclerosis. AB - Aortic atheroma is a known cause of ischemic stroke. However, it is unclear whether ischemic stroke is caused by emboli from aortic atheroma or by accompanying atherosclerosis. In this study, we evaluated lesion patterns of patients with complex aortic plaque (CAP) to assume the underlying pathophysiology. Acute ischemic stroke patients who underwent transesophageal echocardiography were included. CAP was defined as a plaque in the proximal aorta >= 4 mm thick or with a mobile component. The diffusion-weighted imaging lesion patterns of patients with CAP were compared to those with large arterial atherosclerosis (LAA) or cardioembolism (CE). A total of 64 CAP patients, 127 LAA patients, and 80 CE patients were included. Small cortical pattern was more common in the CAP group (45.3%) than in the LAA (7.9%, p < 0.001) or the CE group (23.8%, p = 0.018). A large cortical pattern was more common in the CE group than in the CAP group (p < 0.001), whereas subcortical only pattern tended to be more common in the CAP group than in the CE group (p = 0.057). In multinominal analysis, the CAP group was more likely to have a small cortical lesion than the LAA group [odds ratio (OR) 14.63; 95% confidence interval (CI) 4.67-45.85] or the CE (OR 3.69, 95% CI 1.19-11.39) group. In conclusion, patients with CAP frequently had small cortical lesions or subcortical single lesion. These findings imply that ischemic stroke in aortic atheroma patients is associated with either small emboli or small artery disease.

AB - PURPOSE OF REVIEW: Guidelines were recently published highlighting why esophageal atresia (EA) patients are prone to complication risks, and the need for long-term follow-up. In this review, we will focus on how to investigate and treat potential complications, as well as the pros and cons of different investigative and treatment modalities, and what areas continue to need further research. RECENT FINDINGS: EA patients are at high risk for gastroesophageal reflux and esophageal strictures, and the sequela that result. Extraintestinal manifestations of gastroesophageal reflux disease (GERD) can appear similar to other pathologic diagnoses commonly found in EA patients, such as congenital stricture, eosinophilic esophagitis, esophageal dysmotility, tracheomalacia, recurrent fistula, aspiration, etc. Therefore, it is important to have a standardized way to monitor for these issues. pH impedance allows for detection of nonacid reflux and the height of reflux, which are important in correlating symptoms with reflux episodes. A multidisciplinary approach is beneficial in evaluating and monitoring EA patients in the long term. PMID- 29177553 TI - A novel posterior approach preserving three muscles inserted at C2 in multilevel cervical posterior decompression and fusion using C2 pedicle screws. AB - PURPOSE: To present a novel posterior approach in multilevel cervical posterior decompression and fusion (PDF) using C2 pedicle screws that preserves the rectus capitis posterior major, oblique capitis inferior, and semispinalis cervicis. METHODS: We analyzed 30 consecutive patients who underwent C2-T1 PDF using an approach that preserved these three muscles without resecting. We assessed O-C2 range of motion (ROM), cross-sectional area of the cervical posterior muscles, rotational ROM, visual analog scale (VAS) for axial pain, neck disability index (NDI), and limitations of activities of daily living (ADL) involving neck movements. RESULTS: Mean preoperative O-C2 ROM (23.6 degrees ) was significantly increased postoperatively (33.0 degrees ). Mean atrophy rate of the cross sectional area was 3.9%. Postoperatively, 69.8% of the preoperative rotational ROM (113.3 degrees ) was retained. The preoperative VAS for axial pain and the NDI did not increase postoperatively. The postoperative O-C2 ROM (33.9 degrees ) in 26 patients for whom extension ADL were possible was significantly larger than that in four patients for whom extension ADL were impossible (26.9 degrees ). The postoperative retained rate of rotational ROM (75.8%) in 18 patients for whom rotation ADL were possible was significantly larger than that in 12 patients for whom rotation ADL were impossible (62.3%). CONCLUSIONS: This is potentially an effective approach for maintaining O-C2 ROM and rotational ROM, which enabled good levels of ADL after C2-T1 PDF. Axial pain and NDI were not worse after PDF. PMID- 29177554 TI - Description of the sagittal alignment of the degenerative human spine. AB - PURPOSE: To present the description of sagittal alignment of the degenerative human spine and its possible evolution. MATERIALS AND METHODS: This is a retrospective observational study of degenerative evolution in spinal alignment in low back pain patients. Full spine EOS(r) sagittal X-rays were analyzed, and pelvic and spinal parameters were measured. Spinal shapes were classified on the hypothesis that the possible sagittal shapes of degenerative spine would be divided into four categories: "classical" Roussouly types 1-4, anteverted types (PT <= 5), retroverted types (PT >= 25) and kyphotic types. RESULTS: A total of 331 patients (280 women and 51 men) were included. "Classic" types 1-4 represented the majority in this cohort (71.9%). Retroverted types made the second most common category with 20.8% of the cohort. Kyphosis group (lumbar and global) make only 5.8% of this cohort, while anteverted group make the lowest incidence (1.5%). Retroverted type 2 with thoracic kyphosis should be considered a separate type and made 1.5% of this cohort. Two theoretical subtypes, retroverted type 1 and type 4 were not found. CONCLUSIONS: This is the first description of degenerative spine disease based on its shape and based on the classification of the normal variation in the sagittal alignment of the human lumbar spine described by Roussouly. Eleven types, divided into classical types, anteverted types, false shapes (retroverted) and kyphotic shapes, are described and an evolution pathway is proposed. An evaluation of surgical results in order to propose a treatment algorithm based on this classification should follow. LEVEL OF EVIDENCE: Level IV cross sectional observational study. PMID- 29177555 TI - Efficacy of photodynamic therapy as adjunct treatment of chronic periodontitis: a systematic review and meta-analysis. AB - Meta-analysis of treatment effects of antimicrobial photodynamic therapy (aPDT) adjunct to non-surgical scaling and root planing (SRP) in comparison to SRP alone on patients with chronic periodontitis. The meta-analysis was performed according to PRISMA statement and Cochrane Collaboration guidelines. Electronic search complemented by hand search assured a high yield of randomized controlled trials (RCTs) of aPDT as adjunct modality to SRP. Differences in probing depth (PD) and clinical attachment level (CAL) were calculated with 95% confidence intervals and pooled in a random effects model. Analysis for intra- and inter-study heterogeneity was provided by chi 2 and I 2 tests, and publication bias was checked by funnel plots. Pooled overall effects of 26 RCTs attested significant benefits of aPDT adjunct to SRP with respect to PD reduction (MD 0.37; 95% CI 0.12-0.53; P < 0.0001) and CAL gain (MD 0.33; 95% CI 0.19-0.48; P < 0.00001) after 3 and 6 months. Sensitivity analysis minimized heterogeneity of PD reduction (MD 0.21; 95% CI 0.13-0.30; P < 0.00001) and CAL gain (MD 0.36; 95% CI 0.27-0.46). aPDT adjunct to SRP provides significant PD reduction and CAL gain in treatment of chronic periodontitis. This moderate effect was found after 3 and 6 months which is short from a clinical perspective. PMID- 29177558 TI - On Applicability of Tunable Filter Bank Based Feature for Ear Biometrics: A Study from Constrained to Unconstrained. AB - In this paper, an overall framework has been presented for person verification using ear biometric which uses tunable filter bank as local feature extractor. The tunable filter bank, based on a half-band polynomial of 14th order, extracts distinct features from ear images maintaining its frequency selectivity property. To advocate the applicability of tunable filter bank on ear biometrics, recognition test has been performed on available constrained databases like AMI, WPUT, IITD and unconstrained database like UERC. Experiments have been conducted applying tunable filter based feature extractor on subparts of the ear. Empirical experiments have been conducted with four and six subdivisions of the ear image. Analyzing the experimental results, it has been found that tunable filter moderately succeeds to distinguish ear features at par with the state-of-the-art features used for ear recognition. Accuracies of 70.58%, 67.01%, 81.98%, and 57.75% have been achieved on AMI, WPUT, IITD, and UERC databases through considering Canberra Distance as underlying measure of separation. The performances indicate that tunable filter is a candidate for recognizing human from ear images. PMID- 29177551 TI - Diagnosis and management of gastrointestinal complications in adult cancer patients: 2017 updated evidence-based guidelines of the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO). AB - Cancer patients frequently suffer from gastrointestinal complications. In this manuscript, we update our 2013 guideline on the diagnosis and management of gastrointestinal complications in adult cancer patients by the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO). An expert group was put together by the AGIHO to update the existing guideline. For each sub-topic, a literature search was performed in PubMed, Medline, and Cochrane databases, and strengths of recommendation and the quality of the published evidence for major therapeutic strategies were categorized using the 2015 European Society for Clinical Microbiology and Infectious Diseases (ESCMID) criteria. Final recommendations were approved by the AGIHO plenary conference. Recommendations were made with respect to non infectious and infectious gastrointestinal complications. Strengths of recommendation and levels of evidence are presented. A multidisciplinary approach to the diagnosis and management of gastrointestinal complications in cancer patients is mandatory. Evidence-based recommendations are provided in this updated guideline. PMID- 29177557 TI - Can checkpoint inhibitor therapy improve response to chemotherapy? PMID- 29177556 TI - Comparison of the effect of root surface modification with citric acid, EDTA, and aPDT on adhesion and proliferation of human gingival fibroblasts and osteoblasts: an in vitro study. AB - Root demineralization is used in Periodontics as an adjuvant for mechanical treatment. The aim of this study was to evaluate the effects of root surface modification with mechanic, chemical, and photodynamic treatments on adhesion and proliferation of human gingival fibroblasts and osteoblasts. Root fragments were treated by scaling and root planing (C-control group), EDTA (pH 7), citric acid plus tetracycline (CA-pH 1), and antimicrobial photodynamic therapy (aPDT) with toluidine blue O and red laser (pH 4). Cells were seeded (104 cells/well, 6th passage) on root fragments of each experimental group and cultured for 24, 48, and 72 h. Cells were counted in scanning electron microscopy images by a calibrated examiner. For fibroblasts, the highest number of cells were present at 72-h period (p < 0.05). EDTA group showed a very low number of cells in relation to CA group (p < 0.05). CA and aPDT group presented higher number of cells in all periods, but without differences between other treatment groups (p > 0.05). For osteoblasts, there was a significant increase in cell numbers for aPDT group at 72 h (p < 0.05). In conclusion, aPDT treatment provided a positive stimulus to osteoblast growth, while for fibroblasts, aPDT and CA had a tendency for higher cell growth. PMID- 29177559 TI - Spanish consensus on treat to target for osteoporosis. AB - : To reach a Spanish expert consensus on a treat-to-target strategy in osteoporosis, a Delphi Consensus Study has been developed. Most of the experts (59.8%) were rheumatologist with a mean clinical experience of 21.3 years (SD 8.5). Consensus was achieved for 70% of the items. Therapeutic objectives, patient follow-up scheme, treatment failure criteria, and appropriate treatment choice for use in T2T strategy in Spain have been defined. INTRODUCTION: The paper aims to achieve a Spanish expert consensus on a treat-to-target (T2T) strategy in osteoporosis. METHODS: A scientific committee led the project and was involved in expert panel identification and Delphi questionnaire development. Two Delphi rounds were completed. The first-round questionnaire included 24 items and assessed, using a seven-point Likert scale, the experts' wish (W) and prognosis (P) in 5 years for each topic (applicability, therapeutic objectives, patient follow-up, and possible treatment to be prescribed). Items for which there was no consensus in the first round were included in the second round. Consensus was defined as >=75% agreement (somewhat/mostly/entirely agree) or disagreement (somewhat/mostly/entirely disagree) responses. RESULTS: Of the experts, 112 and 106 completed the first and second rounds, respectively. 59.8% were rheumatologists with a mean clinical experience of 21.3 years (SD 8.5). Consensus was achieved for 70% of the items, and was established regarding the utility of a T2T strategy to define therapeutic objectives, optimal follow-up, and therapeutic algorithm. Participants agreed on the utility of the bone mineral density (BMD) value (T-score >-2.5 SD for spine and >-2.5/-2.0 SD for femoral neck), lack of fractures, and fracture risk (FRAX) as therapeutic objectives. For measuring BMD changes, consensus was achieved on the suitability of hip and femoral neck locations. Experts agreed to consider treatment failure as when a significant BMD gain could not be achieved, or when a new fracture occurs within 2-3 years. There was consensus that all proposed therapies should achieve a therapeutic target through T2T strategy (treatments with the highest consensus scores were denosumab and teriparatide). CONCLUSION: The therapeutic objectives, patient follow-up scheme, treatment failure criteria, and appropriate treatment choice for use in T2T strategy in Spain have been established by a panel of experts. Some aspects nevertheless still require further analysis. PMID- 29177560 TI - The Clinical Significance of Informant Agreement in Externalizing Behavior from Age 3 to 14. AB - The objective of the current study was to test to what extent agreement between preschool teachers (using a questionnaire-based assessment) and clinicians (using a clinician-rated behavioral task) with regard to externalizing problems in early childhood was predictive of parent reports of children's externalizing behavior trajectory from age 3 to age 14. The prospective longitudinal study was conducted over five waves with 111 clinically referred children aged 3-5 years in wave 1. Analyses were conducted using a multilevel modeling framework. The results of the conditional model testing the association of informant agreement with behavioral trajectories show that the greater the number of informants reporting a high level of behavioral problems in early childhood, the more the trajectory increases until adolescence. The results stress the importance of multi-informant assessment not only for methodological reasons but in order to target at-risk children. PMID- 29177562 TI - Toxicity and efficacy of autologous hematopoietic cell transplantation in elderly patients with aggressive lymphoma: a historical prospective study. AB - High-dose therapy followed by autologous hematopoietic cell transplantation (HCT) prolongs overall survival in patients under 65 years old with relapsed aggressive lymphoma. We aimed to explore the toxicity and efficacy of HCT in patients over 65 years with aggressive lymphoma compared with younger patients. We compared the transplantation outcomes between patients >= 65 years (n = 58) and 55-64 years (n = 44) with chemosensitive aggressive lymphoma (DLBCL, MCL and TCL) that underwent HCT between 1999 and 2016 in the Tel-Aviv Medical Center. The median age was 68 (range, 65-74) and 61 (range, 55-64) years, respectively. There were no differences in the incidences of grade 3-4 mucositis, documented infections and pulmonary complications between the two groups. There was no difference in the incidences of secondary malignancies, relapse (p = .26), non-relapse mortality, (p = .77) and overall survival (p = .53). Multivariate analysis revealed that smoking was a risk factor for non-relapse mortality, while partial remission and > 2 lines of treatment prior HCT were associated with higher risk for relapse. Psycho-socioeconomic score was associated with prolonged hospitalization after HCT and recurrent hospitalizations. We conclude that patients >= 65 years old with aggressive lymphoma, compared to younger counterparts, have similar transplantation outcome. Improving habits and psychosocial factors may further improve outcomes in these patients. PMID- 29177561 TI - How can and should we optimize extracorporeal shockwave lithotripsy? AB - It is well recognized that the popularity of extracorporeal shock wave lithotripsy (SWL), despite its non-invasive character, has decreased during recent years. This is partly explained by the technological achievements in endoscopy and urologists' enthusiasm for such procedures. Another explanation is that many urologists have been insufficiently successful with SWL. The latter effect might to some extent be a result of the performance of the lithotripter used, but in too many cases, it is evident that the principles of how shock wave lithotripsy should be carried out are poorly applied. The purpose of this article is to emphasize some important aspects on how SWL best should be used. Based on decades of experience, it stands to reason that success with SWL does not come automatically and attention has to be paid to all details of this technique. PMID- 29177563 TI - The impact of detention on the social-emotional wellbeing of children seeking asylum: a comparison with community-based children. AB - Accumulating literature demonstrates that immigration detention is harmful to children. However, there is a scarcity of scientifically rigorous and reliable data about the health of children held in detention facilities. The aim of the study was to compare a community-based population of recently arrived refugee children flown into Australia, not detained, resettled in a non-urban area, with a population of children who arrived by boat seeking asylum, detained since arrival. The parent-version of the strength and difficulties questionnaire (SDQ) of children aged 4-15 years was compared in children living in the community with those held in detention. We compared 86 children who had a parent-completed SDQ performed, 38 (44%) in the community group and 48 (56%) in the detention group. The community sample had been living in Australia for 325 days, with no time in detention. The detention sample had been living in detention for a mean of 221 days. The mean age was similar for the community and detention sample at 8.4 years (P = 0.18). In the total sample, children in the detention group had significantly higher SDQ total difficulties scores than children in the community group (P < 0.0001). There was no difference between age groups (P = 0.82). The children in the detention group had, on average, an SDQ total difficulties score that was 12 points higher than children in the community group. Four of the five SDQ subscale scores indicated greater disturbance amongst children in detention (< 0.0001) compared to children living in the community. The detention group had significantly higher scores (P < 0.001) for all except Pro-social scores as compared to Australian norms for the 4-6 and 7-15 years age group. This study presents a rare opportunity to compare the wellbeing of displaced children who were detained following arrival in Australia with those settled in the Australian community since arrival. The community children's scores approximated data from the general Australian childhood population. Children held in detention had significantly more social, emotional and behavioural difficulties than children living in the community, and at levels resembling a clinical cohort. Despite the small sample size, data restrictions and other limitations of the data, statistical significance in differences between the community and detention children is marked and arguably demonstrates the negative impact of post-arrival detention in children who are presumed to have similar levels of pre-arrival adversity. If the objective is to optimise the health and wellbeing of children seeking asylum, removal of post-arrival detention is one of the most powerful interventions available to host countries. PMID- 29177564 TI - Trajectories of mental health problems in children of parents with mental health problems: results of the BELLA study. AB - Children of parents with mental health problems (CPM) have an increased risk for behavioral and psychological problems. This study investigated the age- and gender-specific course as well as predictors of mental health problems in CPM using the longitudinal data (baseline 1- and 2-year follow-ups) of a German general population sample from the BELLA study. Children and adolescents aged 11 17 years (at baseline) who had a parent with mental health problems (n = 325) were analyzed. The mental health problems of the children were assessed by the self-reported version of the strengths and difficulties questionnaire (SDQ). We used individual growth modeling to investigate the age- and gender-specific course, and the effects of risk as well as personal, familial and social protective factors on self-reported mental health problems in CPM. Additionally, data were examined differentiating internalizing and externalizing mental health problems in CPM. Results indicated that female compared to male CPM showed increasing mental health problems with increasing age. Mental health problems in CPM were associated with lower self-efficacy, worse family climate and less social competence over time. Internalizing problems were associated with lower self-efficacy, less social competence and more severe parental mental health problems. Externalizing problems were associated with lower self-efficacy, worse family climate and lower social competence. The main limitations of the study are the short time period (2 years) covered and the report of mental health problems by only one parent. Our findings should be considered in the development of treatment and prevention programs for mental health problems in CPM. PMID- 29177566 TI - Introduction to special section: measuring what matters. PMID- 29177565 TI - Breastfeeding and externalising problems: a quasi-experimental design with a national cohort. AB - Evidence from correlational studies supporting the benefits of breastfeeding on children's externalising problems is mixed. Quasi-experimental approaches can help in better understanding possible 'effects'. We aimed to investigate the longitudinal impact of breastfeeding on externalising problems from childhood into adolescence. Participants included ~ 5000 full-term children, from the Growing Up in Ireland Child Cohort. Externalising problems (conduct problems and hyperactivity) were assessed using both the parent and teacher versions of the Strengths and Difficulties Questionnaire when children were age 9 and 13. Maternal reports were used to collect retrospective information on breastfeeding. Propensity score matching, and adjusting for multiple testing were used to compare the average treatment effects for children who were breastfed. Post matching results revealed statistically significant reductions in hyperactivity at age nine, using both maternal and teacher reports (difference score - 0.48, 95% CI - 0.85, - 0.11; and - 0.51, 95% CI - 0.90, - 0.12, respectively), for children who were breastfed between 6 and 12 months, but not thereafter. These effects were not maintained at age 13. Moreover, no effects of breastfeeding on conduct problems were found at any age, regardless of duration, using either maternal or teacher report. While some benefits of breastfeeding were found, compatible with a temporary modest reduction in hyperactivity, related to being breastfed for 26-50 weeks, these results must be viewed in the context of reliance of propensity score matching on observable characteristics. Additionally, our results are suggestive of a potential non-linear dose-response of breastfeeding on hyperactivity. PMID- 29177567 TI - Mediterranean diet and cardiovascular disease: a systematic review and meta analysis of observational studies. AB - PURPOSE: To provide evidence of the relationship of Mediterranean diet (MD) on incidence/mortality for cardiovascular disease (CVD), coronary/ischemic heart disease (CHD)/acute myocardial infarction (AMI) and stroke (ischemic/hemorrhagic) by sex, geographic region, study design and type of MD score (MDS). METHODS: We performed a systematic review and meta-analysis of observational studies. Pooled relative risks (RRs) were calculated using random-effects models. RESULTS: We identified 29 articles. The RR for the highest versus the lowest category of the MDS was 0.81 (95% CI 0.74-0.88) for the 11 studies that considered unspecified CVD, consistent across all strata. The corresponding pooled RR for CHD/AMI risk was 0.70 (95% CI 0.62-0.80), based on 11 studies. The inverse relationship was consistent across strata of study design, end point (incidence and mortality), sex, geographic area, and the MDS used. The overall RR for the six studies that considered unspecified stroke was 0.73 (95% CI 0.59-0.91) for the highest versus the lowest category of the MDS. The corresponding values were 0.82 (95% CI 0.73 0.92) for ischemic (five studies) and 1.01 (95% CI 0.74-1.37) for hemorrhagic stroke (four studies). CONCLUSIONS: Our findings indicate and further quantify that MD exerts a protective effect on the risk of CVD. This inverse association includes CHD and ischemic stroke, but apparently not hemorrhagic stroke. PMID- 29177568 TI - Tachon Syndrome: Rare Side Effect of Articular Injections of Corticosteroids. A Report of Two Cases. AB - Epidural or intra-articular injections of corticosteroids are an option for the treatment of several pain conditions but are not without adverse effects. Here, we discuss a rare systemic side effect of this therapy: Tachon syndrome. We report two cases, a 64-year-old woman and a 43-year-old man, who presented with Tachon syndrome after receiving, respectively, a shoulder and a lumbar injection of cortivazol 3.75 mg/1.5 ml suspension for injection in pre-filled syringes. The indication for this therapy was, respectively, tendinopathy of the supraspinatus and a mechanical L5 lumbosciatica. A few minutes after receiving the injection, patients experienced acute low back pain, chest tightness, facial erythema and profuse sweating. All vital and biologic parameters were normal. In the first case, improvement was spontaneous and all symptoms resolved in 20 min. The second patient remained under observation and received an intravenous 'physiological' infusion. Both patients recovered fully and returned home. A causal relationship between the corticosteroid injections and the patients' symptoms was very likely because of the acute clinical presentation and the rapid improvement in the patients' conditions and that no further signs indicating other serious complications developed. PMID- 29177569 TI - Low Arid1a Expression Correlates with Poor Prognosis and Promotes Cell Proliferation and Metastasis in Osteosarcoma. AB - AT-rich interactive domain-containing protein 1A (ARID1A) has been shown to function as a tumour suppressor in various malignancies. However, the biological role of ARID1A in osteosarcoma is not clear. The present study aimed to investigate the expression pattern, prognostic value and the biological role of ARID1A in human osteosarcoma. ARID1A expression in 53 osteosarcoma surgical specimens was examined by quantitative real-time polymerase chain reaction, and its clinical significance was analysed. The role of ARID1A in cell proliferation, apoptosis, and metastasis were examined. ARID1A mRNA expression were significantly down-regulated in osteosarcoma tumours from that in matched adjacent non-tumour tissues. ARID1A expression was significantly inversely correlated with tumour stage and distant metastasis, as well as poor overall survival in patients with osteosarcoma. Furthermore, ARID1A mRNA was down regulated in four human osteosarcoma cell lines MG-63, U2OS, HOS and Saos-2. Restoring of ARID1A expression in MG-63 and U2OS cells significantly inhibited cell proliferation and metastasis in vitro. Collectively, our data demonstrate that ARID1A may serve as a tumour suppressor in osteosarcoma progression, and represent a valuable prognostic marker and potential therapeutic target for osteosarcoma.

PMID- 29177570 TI - Genetic risk factors for chemotherapy-induced nausea and vomiting in patients with cancer receiving cisplatin-based chemotherapy. AB - PURPOSE: Younger age and female sex have already been well-known risk factors for chemotherapy-induced nausea and vomiting (CINV), and 30-50% of cancer patients still suffer from CINV. Genetic polymorphisms are suggested to influence antiemetic treatment response. METHODS: This study included a subset of patients previously enrolled in a randomised controlled trial; 156 patients were evaluated. This study aimed to evaluate the role of pharmacogenomic polymorphisms relevant to antiemetic response in patients with cancer receiving cisplatin-based chemotherapy. The study's efficacy endpoint was the proportion of patients with complete response (CR). The study endpoint was evaluated separately in the acute (CR0-24) and delayed (CR24-120) phases. Thirteen polymorphisms were genotyped, and the association of these genotypes with the efficacy of prophylactic antiemetics was then investigated. Confounding variables for the CR were identified using stepwise multivariate logistic regression analysis. Age and sex were included as independent variables by the forced-entry method, and the stepwise method was used to select the pharmacogenomic factors for inclusion as independent variables. RESULTS: Multivariate logistic regression analysis revealed that the ERCC1 8092AA (odds ratio [OR] = 11.25; 95% confidence interval [CI] 1.74-72.71; p = 0.011) and female sex (OR = 3.63; 95% CI 1.14-11.58; p = 0.029) were significant predictors of CR0-24. No significant association of CR24 120 with pharmacogenomic polymorphisms was found via multivariate logistic regression analysis. CONCLUSIONS: ERCC1 polymorphism influenced the extent of CINV control in patients receiving cisplatin-based chemotherapy. TRIAL REGISTRATION: Clinical trial information: UMIN 000009335. PMID- 29177572 TI - Aripiprazole Lauroxil: A Review in Schizophrenia. AB - Aripiprazole lauroxil long-acting injectable (LAI) [Aristada(r)] is an intramuscularly administered, extended-release prodrug of aripiprazole, an established atypical antipsychotic agent that, in terms of its relative position within the class, is at the low end of the risk spectrum for metabolic side effects. In the USA, aripiprazole lauroxil LAI is indicated for the treatment of schizophrenia; approved doses of the drug can be injected once-monthly (q4w), every 6 weeks (q6w) or every 2 months (q8w). The efficacy of the 441 and 882 mg q4w dosages in the treatment of acute exacerbations of schizophrenia and as long term maintenance therapy in stable schizophrenia has been directly demonstrated in a phase III clinical trial and extension, while the efficacy of the 662 mg q4w, 882 mg q6w and 1064 mg q8w dosing regimens has been established on the basis of pharmacokinetic bridging studies. Aripiprazole lauroxil LAI therapy was generally well tolerated, with an adverse event profile consistent with that of oral aripiprazole (with the exception of injection-site reactions), including a low propensity to cause metabolic disturbances. Thus, aripiprazole lauroxil LAI extends the treatment regimen options for patients with schizophrenia; as with other LAI formulations of antipsychotic agents, it can be particularly recommended for patients with recurrent relapses related to nonadherence to oral preparations and for those who prefer this mode of administration. Moreover, unlike aripiprazole monohydrate LAI, the only other commercially available long acting formulation of aripiprazole, aripiprazole lauroxil LAI offers more than one dosing interval option, which may be a potential advantage in terms of tailoring therapy to the needs of individual patients. PMID- 29177573 TI - Triptorelin: A Review of its Use as an Adjuvant Anticancer Therapy in Early Breast Cancer. AB - A 1-month formulation of the gonadotrophin-releasing hormone agonist (GnRHa) triptorelin (Decapeptyl(r)) has been approved in the EU as an adjuvant treatment in combination with tamoxifen or an aromatase inhibitor (AI), of endocrine responsive, early-stage breast cancer in women at high risk of recurrence who are confirmed as premenopausal after completion of chemotherapy. This indication reflects the results of the 5-year SOFT and TEXT studies, especially SOFT, in which ovarian function suppression (OFS; mainly achieved with triptorelin) added to tamoxifen provided a significant benefit in the overall study population of premenopausal patients only after adjusting for prognostic factors. It emerged that adding OFS to tamoxifen produced more pronounced benefits in terms of disease control and, furthermore, increased overall survival in the cohort of higher-risk patients who had previously received chemotherapy. Also, compared with tamoxifen alone, the combination of OFS plus exemestane produced more pronounced benefits in terms of disease control than OFS plus tamoxifen. OFS induces premature menopause; when combined with either tamoxifen or exemestane, it increased the endocrine symptom burden. Nonetheless, the two combinations had distinct tolerability profiles (e.g. vasomotor symptoms and thromboembolic events were more frequent with OFS plus tamoxifen, whereas musculoskeletal symptoms, decreased libido, osteoporosis and fractures were more frequent with OFS plus exemestane). Thus, the combinations of OFS (with triptorelin) plus either tamoxifen or an AI are valid options for the adjuvant treatment of endocrine responsive, early-stage breast cancer in women at sufficiently high risk of relapse to warrant receiving chemotherapy and who remain premenopausal thereafter. Individualized weighing of the potential benefits and adverse effects of treatment is required. PMID- 29177575 TI - Association between sarcoidosis, pulse wave velocity, and other measures of subclinical atherosclerosis: a systematic review and meta-analysis. AB - Chronic inflammation from autoimmune diseases has shown to be a risk factor for atherosclerosis, subsequently leading to cardiovascular disease. Endothelial dysfunction is the early pathogenesis of atherosclerosis in chronic inflammation, but the risk of atherosclerosis in sarcoidosis is less well defined. This meta analysis aimed to explore the association of subclinical atherosclerosis and arterial stiffness in sarcoidosis. A comprehensive search of the MEDLINE and EMBASE databases was performed from date of inception through August 2017. The inclusion criterion was observational studies evaluating the association between sarcoidosis, subclinical atherosclerosis, and arterial stiffness by measuring pulse wave velocity (PWV). Definitions of sarcoidosis and methods to assess PWV were recorded for each study. The pooled standardized mean difference (SMD) of PWV and 95% confidence interval (CI) was calculated using a random-effects meta analysis. The between-study heterogeneity of effect size was quantified using the Q statistic and I 2 . Data were extracted from five observational studies involving 499 subjects. Pooled result demonstrated a significant increase in PWV in patients who have sarcoidosis compared with controls (SMD = 0.57 m/s; 95% CI 0.21-0.92, p value = 0.002, I 2 = 75%, P heterogeneity < 0.01). After excluding studies with low or moderate quality, there was an increase in PWV in sarcoidosis compared with controls (SMD = 0.29 m/s; 95% CI 0.00-0.57, p value = 0.05, I 2 = 55%, P heterogeneity = 0.08). Our study suggests that sarcoidosis is associated with increased arterial stiffness and therefore at risk of subclinical atherosclerosis. Prospective study is required to investigate the association of subclinical atherosclerosis causing overt cardiovascular disease in patients with sarcoidosis. PMID- 29177574 TI - Prevalence of psychological disorders, sleep disturbance and stressful life events and their relationships with disease parameters in Chinese patients with ankylosing spondylitis. AB - Our aim was to investigate the prevalence of psychological disorders, sleep disturbance, and stressful life events in Chinese patients with ankylosing spondylitis (AS) and healthy controls, to assess the correlation between psychological and disease-related variables, and finally to detect powerful factors in predicting anxiety and depression. AS patients diagnosed with the modified New York criteria and healthy controls were enrolled from China. Participants completed a set of questionnaires, including demographic and disease parameters, Zung self-rating anxiety scale (SAS), Zung self-rating depression scale (SDS), the Pittsburgh Sleep Quality Index questionnaire (PSQI), and the Social Readjustment Rating Scale (SRRS). The relationship between psychological and other variables was explored. Stepwise multiple regression was used to determine the contributors to each disorder. Of all the 2772 AS patients, 79.1% were male. Mean age was 28.99 +/- 8.87 years. Prevalence of anxiety, depression, and sleep disturbance was 31.6% (95% CI, 29.9, to 33.4), 59.3% (95% CI, 57.5, to 61.2), and 31.0% (95% CI, 29.3, to 36.7), respectively. 35.3% had stimulus of psychological and social elements (SPSE). Compared with healthy controls, AS patients had more severe psychological disorders, sleep disturbance, and stressful life events (P < 0.01). SDS, overall pain, BASFI, and sleep disturbance were significant contributors of the SAS scores (P < 0.03). SAS, less years of education, and sleep duration were significant contributors of SDS (P < 0.01). AS patients had more anxiety, depression, stressful life events, and sleep disturbance than healthy controls. Pain, functional limitation, sleep disturbance, and education were major contributors to psychological disorders. PMID- 29177576 TI - Variation in biochemical constituents and master elements in common seaweeds from Alexandria Coast, Egypt, with special reference to their antioxidant activity and potential food uses: prospective equations. AB - Biochemical constituents and master elements (Pb, Cr, Cd, Fe, Cu, Zn, Hg, B, Al, SO42-, Na, K, Li, Ca, Mg, and F) were investigated in six different seaweed species from Abu Qir Bay in the Egyptian Mediterranean Sea coast. The moisture level ranged from 30.26% in Corallina mediterranea to 77.57% in Padina boryana. On dry weight basis, the ash contents varied from 25.53% in Jania rubens to 88.84% in Sargassum wightii. The protein contents fluctuated from 8.26% in S. wightii to 28.01% in J. rubens. Enteromorpha linza showed the highest lipids (4.66%) and carbohydrate contents (78.95%), whereas C. mediterranea had the lowest lipid (0.5%), and carbohydrate contents (38.12%). Chlorophylls and carotenoid contents varied among the species. Total antioxidant capacity of the tested green seaweeds had the highest activities followed by brown and red seaweeds which had a similar trend of phenol and tannins contents. High reducing power was observed in all tested seaweeds extract except Ulva lactuca. Brown species had the highest amount of elements followed by red and green seaweeds. Notably, SO42- recorded the highest level in the tested green species (108.05 mg/g dry weight (DW)). The Ca/Mg and K/Na ratios reflected highly significant difference between seaweed species. This study keeps an eye on 29 parameters and by applying stepwise multiple regression analysis, prospective equations have been set to describe the interactions between these parameters inside seaweeds. Accordingly, the tested seaweeds can be recommended as a source of healthy food with suitable ion quotient and estimated daily intake values. PMID- 29177577 TI - Enhanced performance of a novel anodic PdAu/VGCNF catalyst for electro-oxidation in a glycerol fuel cell. AB - This study presents a novel anodic PdAu/VGCNF catalyst for electro-oxidation in a glycerol fuel cell. The reaction conditions are critical issues affecting the glycerol electro-oxidation performance. This study presents the effects of catalyst loading, temperature, and electrolyte concentration. The glycerol oxidation performance of the PdAu/VGCNF catalyst on the anode side is tested via cyclic voltammetry with a 3 mm2 active area. The morphology and physical properties of the catalyst are examined using X-ray diffraction (XRD), field emission scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) spectroscopy. Then, optimization is carried out using the response surface method with central composite experimental design. The current density is experimentally obtained as a response variable from a set of experimental laboratory tests. The catalyst loading, temperature, and NaOH concentration are taken as independent parameters, which were evaluated previously in the screening experiments. The highest current density of 158.34 mAcm-2 is obtained under the optimal conditions of 3.0 M NaOH concentration, 60 degrees C temperature and 12 wt.% catalyst loading. These results prove that PdAu-VGCNF is a potential anodic catalyst for glycerol fuel cells. PMID- 29177578 TI - Abnormalities of Lipoprotein Levels in Liver Cirrhosis: Clinical Relevance. AB - Progressive lipoprotein impairment occurs in liver cirrhosis and is associated with increased morbidity and mortality. The present review aims to summarize the current evidence regarding the prognostic value of lipoprotein abnormalities in liver cirrhosis and to address the need of a better prognostic stratification of patients, including lipoprotein profile assessment. Low levels of lipoproteins are usual in cirrhosis. Much evidence supports the prognostic role of hypolipidemia in cirrhotic patients. In particular, hypocholesterolemia represents an independent predictor of survival in cirrhosis. In cirrhotic patients, lipoprotein impairment is associated with several complications: infections, malnutrition, adrenal function, and spur cell anemia. Alterations of liver function are associated with modifications of circulating lipids. Decreased levels of lipoproteins significantly impact the survival of cirrhotic patients and play an important role in the pathogenesis of some cirrhosis-related complications. PMID- 29177579 TI - Disagreement between splenic switch-off and myocardial T1-mapping after caffeine intake. AB - Caffeine is an adenosine receptor antagonist and a possible cause of inadequate stress perfusion. Splenic switch-off (SSO) and splenic rest-stress T1-mapping have been proposed as indicators of stress adequacy during perfusion cardiac magnetic resonance (CMR). We compared myocardial rest-stress T1-mapping with SSO and splenic rest-stress T1-mapping in patients with and without recent coffee intake. We analyzed 344 consecutive patients suspected of myocardial ischemia with adenosine perfusion CMR. All 146 normal CMR studies with a normal T1-rest of the myocardium, used as standard of reference, were included and divided in two groups. 22 patients accidentally ingested coffee < 4 h before CMR, compared to control group of 124 patients without self-reported coffee intake. Two independent readers graded SSO visually. T1-reactivity (DeltaT1) was defined as percentual difference in T1-rest and T1-stress. Follow-up data were extracted from electronic patients records. In patients with recent coffee intake SSO was identified in 96%, which showed no significant difference with SSO in controls (94%, p = 0.835), however event rates were significantly different (13.6 and 0.8%, respectively (p < 0.001), median FU 17 months). Myocardial DeltaT1 in the coffee group (- 5.2%) was significantly lower compared to control (+ 4.0%, p < 0.001), in contrast to the splenic DeltaT1 (- 3.7 and - 4.0%, p = 0.789). The splenic T1-mapping results failed to predict false negative results. SSO and splenic rest-stress T1-mapping are not reliable indicators of stress adequacy in patients with recent coffee intake. Therefore, the dark spleen sign does not indicate adequate myocardial stress in patients with recent caffeine intake. Myocardial rest-stress T1-mapping is an excellent indicator of stress adequacy during adenosine perfusion CMR. PMID- 29177580 TI - Molecular detection and genetic characterizations of Cryptosporidium spp. in farmed foxes, minks, and raccoon dogs in northeastern China. AB - Cryptosporidium spp. are common intestinal protozoa causing diarrhea in humans and a variety of animal species. With the recent development of fur industry, a large number of fur animals are farmed worldwide, especially in China. The existence of identical Cryptosporidium species/genotypes in humans and fur animals suggests zoonotic potential. In order to assess the presence of zoonotic Cryptosporidium species and/or genotypes in farmed fur animals, 367 fecal specimens were collected from 213 foxes, 114 minks and 40 raccoon dogs farmed in Heilongjiang, Jilin, and Liaoning provinces, northeastern China, during the period from June 2014 to October 2016. By PCR and sequencing of the partial small subunit (SSU) rRNA gene of Cryptosporidium, 20 of 367 (5.4%) animal samples were found to be infected, corresponding to 12 of 213 fox samples (5.6%) and 8 of 114 mink samples (7.0%) screened. Three Cryptosporidium species/genotypes were identified: C. canis (n = 17), C. meleagridis (n = 1) and Cryptosporidium mink genotype (n = 2). Two host-adapted C. canis types (C. canis dog genotype and C. canis fox genotype) were found. By PCR and sequencing of the partial 60 kDa glycoprotein (gp60) encoding gene, one mink genotype isolate was successfully subtyped as XcA5G1R1. The three Cryptosporidium species/genotypes identified in this study have been previously reported in humans suggesting that fur animals infected with Cryptosporidium spp. may pose a risk of zoonotic transmission of cryptosporidiosis, especially for the people working in fur animal farming and processing industry. PMID- 29177581 TI - An apparent Acanthamoeba genotype is the product of a chimeric 18S rDNA artifact. AB - Free-living amoebae of the genus Acanthamoeba are potentially pathogenic protozoa widespread in the environment. The detection/diagnosis as well as environmental survey strategies is mainly based on the identification of the 18S rDNA sequences of the strains that allow the recovery of various distinct genotypes/subgenotypes. The accurate recording of such data is important to better know the environmental distribution of distinct genotypes and how they may be preferentially associated with disease. Recently, a putative new acanthamoebal genotype T99 was introduced, which comprises only environmental clones apparently with some anomalous features. Here, we analyze these sequences through partial treeing and BLAST analyses and find that they are actually chimeras. Our results show that the putative T99 genotype is very likely formed by chimeric sequences including a middle fragment from acanthamoebae of genotype T13, while the 5'- and 3'-end fragments came from a nematode and a cercozoan, respectively. Molecular phylogenies of Acanthamoeba including T99 are consequently erroneous as genotype T99 does not exist in nature. Careful identification of Acanthamoeba genotypes is therefore critical for both phylogenetic and diagnostic applications. PMID- 29177582 TI - The invasive cestode parasite Ligula from salmonids and bullies on the South Island, New Zealand. AB - Freshwater ecosystems are often impacted by biological invasions, including the introduction of exotic parasites capable of infecting native species. Here, we report the occurrence of the introduced tapeworm Ligula sp. from common bully, Gobiomorphus cotidianus, and quinnat salmon, Oncorhynchus tshawytscha, in Lake Hawea, South Island, New Zealand. This parasite has a complex life cycle, reaching its adult stage in fish-eating birds. Worms recovered from the body cavity of fish hosts reached huge sizes (60-300 mm long); however, their low prevalence in fish populations suggests that infections are rare or localised. Molecular analysis (internal transcribed spacer (ITS)1 and ITS2 sequences) confirms that these specimens belong to the genus Ligula and suggests tentative routes of invasion into New Zealand. Monitoring the spread of this parasite is important, as it can impact fish populations and also, when infection levels are high, those of piscivorous birds. PMID- 29177583 TI - Identification and functional analysis of the novel ORF6 protein of porcine circovirus type 2 in vitro. AB - In the present study, the function of a novel ORF6 gene in the PCV2 genome was determined and functionally analyzed in vitro. ORF6 expression was demonstrated by indirect immunofluorescence in PCV2-infected cells. The antibody against ORF6 was detected in PCV2-infected pigs. The start codon of ORF6 was mutated and an infectious clone was used to create an ORF6-deficient mutant virus. Viral DNA replication curves and immunofluorescence analysis indicated that ORF6 is unnecessary for viral replication and ORF6 deletion reduces viral DNA replication in PK-15 cells. The activities of caspases 3 and 8 in ORF6-deficient virus infected cells were significantly different from those in wild-type virus infected cells. The ORF6 protein can increase the expression of IFN-beta, TNF alpha, IL-1b, IL-10, and IL-12p40. These results demonstrated that the newly discovered ORF6 protein may be involved in caspases regulation and the expression of multiple cytokines in PCV2-infected cells. The functions of this gene in viral pathogenesis remain to be further elucidated. PMID- 29177584 TI - Sirtuin 6, a possible therapeutic target for type 2 diabetes. AB - Sirtuin 6 (SIRT6), one of the seven members of mammalian sirtuin family, localizes in the nucleus and primarily regulates chromatin signaling and genomic integrity. Recent studies established the critical role of SIRT6 in the pathophysiology of metabolic disease, as well as its roles in longevity and cancer. These roles that were determined by genetic studies include promoting pancreatic insulin secretion, inhibiting hepatic gluconeogenesis and triglyceride synthesis, and suppressing adiposity, suggesting that SIRT6 activators are promising molecules for treating obesity and diabetes. In contrast, a recent study showed that a synthetic inhibitor of SIRT6 improved glucose tolerance in a type 2 diabetes mouse model, associated with increased glycolysis and the expression of glucose transporter GLUT-1 and 4 in skeletal muscle, providing proof-of-concept evidence of SIRT6 inhibition as a treatment for diabetes. This review summarizes the confounding findings on the role of SIRT6 in metabolic homeostasis and discusses the possible relationships of these findings as they relate to the use of SIRT6 as a therapeutic target for type 2 diabetes and related diseases. PMID- 29177585 TI - The role of exercise-induced myokines in regulating metabolism. AB - Exercise has beneficial effects in ameliorating metabolic disorders, and a combined therapeutic regimen of regular exercise and pharmaceutical treatment is often recommended. Exercise biology is complex and it involves various metabolic and molecular changes that translate into changes in substrate utilization, enzyme activation, and alternatively, improvement in exercise performance. Besides the effect of exercise on muscle metabolism, it has recently been discovered that contracting muscle can induce secretion of molecules called myokines. In the past few decades, a number of myokines have been discovered, such as interleukin-6, irisin, myostatin, interleukin-15, brain-derived neurotrophic factor, beta-aminoisobutyric acid, meteorin-like, leukemia inhibitory factor, and secreted protein acidic and rich in cysteine, through secretome analysis. The existence of myokines has enhanced our understanding of how muscles communicate with other organs such as adipose tissue, liver, bone, and brain to exert beneficial effects of exercise at the whole body level. In this review, we focus on the role of these myokines in regulating local muscle metabolism as well as systemic metabolism in an autocrine/paracrine/endocrine fashion. The therapeutic potential of myokines and the natural or synthetic compounds known to date that regulate myokines are also discussed.

AB - A new phenolic amide, named cis-terrestriamide (7), together with ten known compounds (1-6, 8-11), were isolated from the methanolic extract of the fruits of Tribulus terrestris. The structure of 7 was elucidated on the basis of extensive analyses of 1D and 2D nuclear magnetic resonance spectroscopic and high resolution mass spectrometry data. Compounds 1, 2, 5, 6, 8, 9, and 11 exhibited inhibitory effects on the lipopolysaccharide-stimulated nitric oxide production in RAW 264.7 cells, with IC50 values of 18.7-49.4 MUM. PMID- 29177589 TI - Ultrasound guided core needle biopsy prior to thermo ablative treatment of uterine tumors: first results. AB - PURPOSE: This study aimed at evaluating the diagnostic yield for core needle biopsies of uterine fibroids before laparoscopic radiofrequency volumetric thermal ablation (RFVTA) with the aim of sonographic imaging. This study was in the context of a randomized, prospective, single-center, longitudinal comparative study in which RFVTA and laparoscopic myomectomy for symptomatic uterine fibroids were compared. METHODS: All patients of the RFVTA-arm received a core needle biopsy under the guidance of an intraoperative laparoscopic ultrasound system. The Tissue samples were observed histologically. RESULTS: 24 patients were included and received in the median 3.17 biopsies (range 2-7). 45.8% of the fibroids were intramural. In 92% uterine leiomyoma was detected, in 4% a cell rich leiomyoma and in 4% a smooth muscle tumor with uncertain malignant potential (STUMP). There were no complications caused by core needle biopsy. CONCLUSIONS: Ultrasound guided core needle biopsy can be used to receive a histological result before treating uterine fibroids with thermo surgical methods like RFVTA. PMID- 29177587 TI - Intranasal Therapy to Stop Status Epilepticus in Prehospital Settings. AB - Status epilepticus (SE) is a medical emergency characterized by uncontrolled, prolonged seizures with rapid and widespread neuronal damage. Patients that suffer from longer episodes of SE are more likely to have poorer clinical outcomes and a higher cost of healthcare. Understanding novel molecular mechanisms that regulate inhibitory and excitatory neurotransmission that initiate SE and the necessary medical infrastructure to stop SE could help identify targets for early intervention. Intranasal administration of benzodiazepines may shorten the time between initiation and cessation of seizures when compared to other routes of administration. Current pharmaceutical administration guidelines are appropriate for sporadic incidences of SE, but exploring other approaches is necessary to prepare for situations involving multiple patients outside of a hospital, such as a massive chemical weapons attack. Intranasal drug delivery helps to circumvent the blood-brain barrier and offers a noninvasive way to quickly administer drugs in settings that require an immediate response, such as nerve agent exposure. In addition, examining the intranasal delivery of new drugs, such as nanotherapeutics, may lead to more effective, noninvasive, scalable, and portable methods of treating SE. PMID- 29177588 TI - Treatment of giant paraesophageal hernia: pro laparoscopic approach. AB - PURPOSE: Giant paraesophageal hernias (GPEH) are relatively uncommon and account for less than 5% of all primary hiatal hernias. Giant Secondary GPEH can be observed after surgery involving hiatal orifice opening, such as esophagectomy, antireflux surgery, and hiatal hernia repair. Surgical treatment is challenging, and there are still residual controversies regarding the laparoscopic approach, even though a reduced morbidity and mortality, as well as a shorter hospital stay have been demonstrated. METHODS: A Pubmed electronic search of the literature including articles published between 1992 and 2016 was conducted using the following key words: hiatal hernia, paraesophageal hernias, mesh, laparoscopy, intrathoracic stomach, gastric volvulus, diaphragmatic hernia. RESULTS: Given the risks of non-operative management, GPEH surgical repair is indicated in symptomatic patients. Technical steps for primary hernia repair include hernia reduction and sac excision, correct repositioning of the gastroesophageal junction, crural repair, and fundoplication. For secondary hernias, the surgical technique varies according to hernia type and components and according to the approach used during the first surgery. There is an ongoing debate regarding the best and safest method to close the hiatal orifice. The laparoscopic approach has demonstrated a lower postoperative morbidity and mortality, and a shorter hospital stay as compared to the open approach. A high recurrence rate has been reported for primary GPEH repair. However, recent studies suggest that recurrence does not reduce symptomatic outcomes. CONCLUSIONS: The laparoscopic treatment of primary and secondary GPEH is safe and feasible in elective and emergency settings, especially in high-volume centers. The procedure is still challenging. The main steps are well defined. However, there is still room for improvement to lower the recurrence rate. PMID- 29177590 TI - Risk of parametrial invasion in women with early stage cervical cancer: a meta analysis. AB - PURPOSE: To first evaluate the predictive value of lymph-vascular space invasion (LVSI) and pelvic lymph node metastases (LNM) to parametrial invasion (PI) in patients with early stage cervical cancer. METHODS: A systematic search of electronic databases was conducted to identify publications exploring the association between LVSI, LNM, and PI. The following databases were searched: PubMed/Medline and Web of Science. Twenty relevant studies were included. Pooling of results was done based on these studies and a diagnostic meta-analysis was performed. RESULTS: 20 articles and a total of 7373 cases were included in the meta-analysis. 17 studies analyzed the correlation between LVSI and PI and 18 studies evaluated the correlation between LNM and PI. The existence of LVSI accelerated PI with OR being 7.37 (95% CI 5.70-9.54) in fixed-effect model and 7.32 (95% CI 4.65-10.39) in random effects model. LVSI shows high sensitivity of 0.80 and the AUC was 0.82. The existence of LNM accelerated PI. LNM shows the highest specificity of 0.90 and the AUC was 0.77. CONCLUSIONS: Both LVSI and LNM are associated with PI. Conization and lymphadenectomy might be helpful to predict the parametrial status of patients with early stage cervical cancer. In addition, the results of this meta-analysis are helpful for designing further prospective clinical trials. PMID- 29177591 TI - MicroRNA-21 promotes proliferation, migration, and invasion of cervical cancer through targeting TIMP3. AB - BACKGROUND: The expression of microRNA-21 (miR-21) is up-regulated in various cancers, including cervical cancer. However, the function of miR-21 through tissue inhibitor of metalloproteinase 3 (TIMP3) on the proliferation, migration, and invasion in cervical cancer is still unclear. METHODS: A total of 60 paired fresh cervical cancer tissues, the corresponding adjacent non-neoplastic tissues and serum samples were collected from cervical cancer patients, while 60 matched normal tissues and serum samples were collected from the control group. MiR-21 expression was evaluated by quantitative real-time polymerase chain reaction (qRT PCR). TIMP3 expression was evaluated by Western blot and qRT-PCR. Cell proliferation was determined by MTT assay. Migratory and invasive activities were assessed by cell migration and invasion assays, respectively. Luciferase reporter assay was employed to validate the direct targeting of TIMP3 by miR-21. RESULTS: MiR-21 was up-regulated in cervical cancer tissues and serum samples, in contrast, TIMP3 was down-regulated in cervical cancer tissues. MiR-21 promoted the proliferation, viability and the migratory and invasive activities of cervical cancer cells through targeting TIMP3. Overexpression of TIMP3 attenuated the positive effects of miR-21. CONCLUSIONS: These findings provide a novel insight into the molecular functions of miR-21 in cervical cancer, which may be used as a diagnostic and prognostic biomarker for the treatment of cervical cancer in the future. PMID- 29177592 TI - Hyperandrogenemia and ovarian reserve in patients with Mayer-Rokitansky-Kuster Hauser syndrome type 1 and 2: potential influences on ovarian stimulation. AB - PURPOSE: This study aimed to analyze the hormone profiles, to detect the rate of hyperandrogenemia and to investigate the potential effect of Mayer-Rokitansky Kuster-Hauser syndrome (MRKHS) on ovarian reserve, as reflected by the serum Anti Mullerian hormone (AMH) levels. Clinical implications were analyzed by including our own experiences with three patients after ovarian stimulation in preparation for uterus transplantation. METHODS: Serum samples of 100 patients with MRKHS (50 patients with MRKHS type 1 and 50 with type 2) were analyzed and compared to 50 individually age-matched healthy controls. Blood samples for hormone analyses were collected routinely during the clinical visit. RESULTS: The mean age was 20.0 years for MRKHS type 1, MRKHS type 2 and healthy controls. Compared to healthy controls, there was no significant difference in AMH values in the MRKH patients. As shown in previous studies, the proportion of hyperandrogenemia without clinical symptoms was significantly higher in MRKHS type 1 (52%; p < 0.001) and type 2 (56%; p < 0.001) patients when compared to age-matched controls. In preparation for uterus transplantation, three patients were stimulated with FSH/hMG for mean 14.2 days and the mean number of aspirated oocytes was 13.2 (3-22), while 8.3 (2-10) oocytes could be fertilized and cryopreserved. The mean fertilization rate was 51.2% (30-67%). CONCLUSION: The rate of hyperandrogenemia was significantly higher in MRKH patients compared to healthy age-matched controls. Though, ovarian reserve (AMH level) was not reduced compared to controls. Future studies are needed to identify optimal ovarian stimulation protocols as well as to implement a systematic multicenter reporting system. PMID- 29177593 TI - Practical recommendations for fertility preservation in women by the FertiPROTEKT network. Part I: Indications for fertility preservation. AB - PURPOSE: Most guidelines about fertility preservation are predominantly focused on scientific evidence, but are less practically orientated. Therefore, practically oriented recommendations are needed to support the clinician in daily practice. METHODS: A selective literature search was performed based on the clinical and scientific experience of the authors, focussing on the most relevant diseases and gynaecological cancers. This article (Part I) provides information on topics that are essential for the fertility preservation indication, such as disease prognosis, disease therapy and its associated risks to fertility, recommending disease-specific fertility preservation measures. Part II specifically focusses on fertility preservation techniques. RESULTS: In breast cancer patients, fertility preservation such as ovarian tissue and oocyte cryopreservation is especially recommended in low-stage cancer and in women < 35 years of age. In Hodgkin's lymphoma, the indication is mainly based on the chemotherapy regime as some therapies have very low, others very high gonadotoxicity. In borderline ovarian tumours, preservation of fertility usually is achieved through fertility sparing surgery, ovarian stimulation may also be considered. In cervical cancer, endometrial cancer, rheumatic diseases and other malignancies such as Ewing sarcoma, colorectal carcinoma, non-Hodgkin lymphoma, leukaemia etc., several other factors must be considered to enable an individual, stage-dependent decision. CONCLUSION: The decision for or against fertility preservation depends on the prognosis, the risks to fertility and individual factors such as prospective family planning. PMID- 29177595 TI - Practice patterns and survival outcomes of intracranial germinoma: an analysis of the National Cancer Database. AB - The goal of the study is to examine the practice pattern and survival outcome of adult and pediatric patients with intracranial germinoma. Patients from the National Cancer Database (NCDB) brain tumor registry between the years 2004-2014 with intracranial germinoma were extracted for analysis. Patients who had distant metastasis, received no treatments, or only surgery/chemotherapy alone were excluded. An age cutoff of > 21 years old was used to define the pediatric population. Patients were stratified by the treatments radiation therapy alone (RT) and chemotherapy followed by radiation therapy (C + RT). 445 patients with intracranial germinoma meeting our inclusion criteria were identified. Of the adult patients, 65.7% received RT and 34.3% received C + RT, compared to the pediatric patients, where 31.8% received RT and 68.2% received C + RT. Those patients who received C + RT had a lower radiation dose compared to the RT group (p < 0.001). The 5 and 10 year overall survival (OS) for the entire cohort was 92.6 and 87.9%, respectively. Univariate analysis demonstrated improved OS with younger age, private insurance, C + RT treatment, and pediatric patients. Only age and insurance type remained significant on multivariate analysis. The 5 year OS was 92.6% (RT) versus 97.2% (C + RT) (p = 0.307) and 83.4% (RT) versus 95.4% (C + RT) (p = 0.122) in the pediatric and adult patients, respectively. There is a higher use of C + RT with an accompanied reduction in RT dose in the treatment of intracranial germinoma. There is no difference in survival between the treatment approaches of RT or C + RT in the NCDB patient cohort. PMID- 29177594 TI - Efficacy and safety of Levetiracetam vs. other antiepileptic drugs in Hispanic patients with glioblastoma. AB - Epilepsy is a common symptom in patients with glioblastoma (GB). 213 patients with GB from RedLANO follow-up registry were included. All patients underwent surgery, if feasible, followed by chemoradiation based on temozolomide (Stupp platform). Information was recorded regarding demographics, seizure timing, anti epileptic drugs (AEDs), dosage, time to next seizure, total seizures in 6 months, and main side effects of AEDs. The relationship between epilepsy treatment and overall survival (OS) was evaluated. Mean age was 53 years old and 56.8% were male. Seventy-eight patients (37%) were treated with levetiracetam (LEV), 27% were given another AED and 36% did not require any AED. Choice of AED was not associated with age (p = 0.67), performance status (p = 0.24) or anatomic tumor site (p = 0.34). Seizures and AED requirement were greater in those having primary GB (p = 0.04). After starting an AED, the mean time until next crisis was 9.9 days (SD +/- 6.3), which was shorter in those receiving LEV (p = 0.03); mean number of seizures during the first 3 and 6 months were 2.9 and 4, respectively. Most patients treated with LEV (n = 46) required less than two medication adjustments compared to those treated with other AEDs (p = 0.02). Likewise, less patients exposed to LEV required a coadjuvant drug (p = 0.04). Additionally, patients receiving LEV had significantly less adverse effects compared to patients treated with another AED. OS was significantly higher in the group treated with LEV compared to other AEDs (25.5 vs. 17.9 months; p = 0.047). Patients treated with LEV had better seizure control and longer OS compared to other AEDs. PMID- 29177596 TI - Sintering Behavior of Spark Plasma Sintered SiC with Si-SiC Composite Nanoparticles Prepared by Thermal DC Plasma Process. AB - The Si-coated SiC (Si-SiC) composite nanoparticle was prepared by non-transferred arc thermal plasma processing of solid-state synthesized SiC powder and was used as a sintering additive for SiC ceramic formation. Sintered SiC pellet was prepared by spark plasma sintering (SPS) process, and the effect of nano-sized Si SiC composite particles on the sintering behavior of micron-sized SiC powder was investigated. The mixing ratio of Si-SiC composite nanoparticle to micron-sized SiC was optimized to 10 wt%. Vicker's hardness and relative density was increased with increasing sintering temperature and holding time. The relative density and Vicker's hardness was further increased by reaction bonding using additional activated carbon to the mixture of micron-sized SiC and nano-sized Si-SiC. The maximum relative density (97.1%) and Vicker's hardness (31.4 GPa) were recorded at 1800 degrees C sintering temperature for 1 min holding time, when 0.2 wt% additional activated carbon was added to the mixture of SiC/Si-SiC.

PMID- 29177598 TI - Systemic metabolism and energy consumption after microsurgical clipping and endovascular coiling for aneurysmal subarachnoid hemorrhage. AB - BACKGROUND: The postoperative metabolic states of subarachnoid hemorrhage (SAH) patients were investigated using indirect calorimetry (IDC) and various nutritional evaluations to establish any difference in perioperative metabolic and nutritional states between microsurgical and endovascular treatment. METHODS: This study included 30 acute aneurysmal SAH patients with ruptured intracranial aneurysms treated by surgical clipping (n = 16) or coil embolization (n = 14) at a single institute. The resting energy expenditure (REE) and respiratory quotient were measured using IDC on days 1, 4, 7, 10, 14, and 17-21 after the operation. Various blood tests, including C-reactive protein (CRP) and prealbumin, were evaluated on the same days. RESULTS: The clipping group showed a significant increase in REE/basal energy expenditure (BEE) compared with the coiling group on days 1 and 4 (p = 0.04 and 0.03, respectively). No significant differences were found on days 7, 10, 14, and 17-21. The mean REE/BEE on days 1-14 and 1-21 showed no significant differences between the groups with repeated measures analysis of variance. The clipping group showed a significant decrease of prealbumin on day 4 and significant increase in CRP on days 1, 4, and 7. CONCLUSIONS: The clipping group was in the hypermetabolic state compared with the coiling group during the very early postoperative period. However, the difference associated with the treatment modality was relatively small compared to the effects of the SAH and of the sequelae. PMID- 29177600 TI - Pagers, Smartphones, and HIPAA: Finding the Best Solution for Electronic Communication of Protected Health Information. AB - Electronic communication is a topic that applies broadly to the professional activities of every physician and the pager has been the gold standard of communication for decades. We believe that this is a dated technology that is holding clinicians back from better, more efficient alternatives, particularly smartphones. In this manuscript, we examine the paradoxical reliance on pagers in academic medicine, at a time when the use of smartphones and text messaging is the subject of intense scrutiny with respect to its standing under the Health Insurance Portability and Accountability Act (HIPAA). We provide previously unreported data regarding the electronic communication practices of academic medical centers in the United States, which we obtained through a survey of Designated Institutional Officials. These data highlight both the controversy around text messaging and HIPAA and a puzzling widespread reliance on pagers as an alternative. PMID- 29177599 TI - Obesity in Children: Definition, Etiology and Approach. AB - Childhood obesity is an important public health issue worldwide. Urbanization, sedentary lifestyle and change in food habits are the chief reasons behind this pandemic. In a small proportion of children, obesity is the result of endocrine, syndromic or monogenic causes. The present paper summarizes the methods, definitions and cut-offs for identification of obesity in children. We have briefly reviewed the various techniques used for estimation of body fat in children and the cut-offs for defining obesity based on body fat percentage, and the reference curves based on body mass index and waist circumference. The etiology of obesity in children, including individual behaviors, macro- and micro environmental influences, and endocrine causes have been discussed, and an approach to etiological assessment of obese children has been presented. Special emphasis has been laid on clinical pointers that suggest the presence of syndromic, endocrine or monogenic forms of obesity, such as, short stature, dysmorphism, neurocognitive impairment and early age at onset. PMID- 29177601 TI - Streptomyces ginkgonis sp. nov., an endophyte from Ginkgo biloba. AB - A novel endophytic actinomycete strain, designated KM-1-2T, was isolated from seeds of Ginkgo biloba at Yangling, China. A polyphasic approach was used to study the taxonomy of strain KM-1-2T and it was found to show a range of phylogenetic and chemotaxonomic properties consistent with those of members of the genus Streptomyces. The diamino acid of the cell wall peptidoglycan was identified as LL-diaminopimelic acid. No diagnostic sugars were detected in whole cell hydrolysates. The predominant menaquinones were identified as MK-9(H6) and MK-9(H8). The diagnostic phospholipids were found to be phosphatidylethanolamine and phosphatidylcholine. The DNA G + C content of the novel strain was determined to be 72.9 mol%. The predominant cellular fatty acids (> 10.0 %) were identified as iso-C14 : 0, iso-C16 : 0, C16 : 0 and C17 : 0 cyclo. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the strain is closely related to Streptomyces carpaticus JCM 6915T (99.3%), Streptomyces harbinensis DSM 42076T (98.9%) and Streptomyces cheonanensis JCM 14549T (98.5%). DNA-DNA hybridizations with these three close relatives gave similarity values of 39.1 +/- 1.9, 35.8 +/- 2.3, and 47.4 +/- 2.7%, respectively, which indicated that strain KM-1-2T represents a novel species of the genus Streptomyces. This is consistent with the morphological, physiological and chemotaxonomic data. Cumulatively, these data suggest that strain KM-1-2T represents a novel Streptomyces species, for which the name Streptomyces ginkgonis sp. nov. is proposed, with the type strain KM-1 2T (= CCTCC AA2016004T = KCTC 39801T).

PMID- 29177603 TI - Impact of multi-gene mutational profiling on clinical trial outcomes in metastatic breast cancer. AB - PURPOSE: Next-generation sequencing (NGS) has identified recurrent genomic alterations in metastatic breast cancer (MBC); however, the clinical utility of incorporating routine sequencing to guide treatment decisions in this setting is unclear. We examine the frequency of genomic alterations in MBC patients from academic and community hospitals and correlate with clinical outcomes. METHODS: MBC patients with good performance status were prospectively recruited at the Princess Margaret Cancer Centre (PM) in Canada. Molecular profiling on DNA extracted from FFPE archival tissues was performed on the Sequenom MassArray platform or the TruSeq Amplicon Cancer Panel (TSACP) on the MiSeq platform. Clinical trial outcomes by RECIST 1.1 and time on treatment were reviewed retrospectively. RESULTS: From January 2012 to November 2015, 483 MBC patients were enrolled and 440 were genotyped. At least one somatic mutation was identified in 46% of patients, most commonly in PIK3CA (28%) or TP53 (13%). Of 203 patients with >= 1 mutation(s), 15% were treated on genotype-matched and 9% on non-matched trials. There was no significant difference for median time on treatment for patients treated on matched vs. non-matched therapies (3.6 vs. 3.8 months; p = 0.89). CONCLUSIONS: This study provides real-world outcomes on hotspot genotyping and small targeted panel sequencing of MBC patients from academic and community settings. Few patients were matched to clinical trials with targeted therapies. More comprehensive profiling and improved access to clinical trials may increase therapeutic options for patients with actionable mutations. Further studies are needed to evaluate if this approach leads to improved clinical outcomes. PMID- 29177605 TI - Evaluation of applying IHC4 as a prognostic model in the translational study of Intergroup Exemestane Study (IES): PathIES. AB - BACKGROUND: Intergroup Exemestane Study (IES) was a randomised study that showed a survival benefit of switching adjuvant endocrine therapy after 2-3 years from tamoxifen to exemestane. This PathIES aimed to assess the role of immunohistochemical (IHC)4 score in determining the relative sensitivity to either tamoxifen or sequential treatment with tamoxifen and exemestane. PATIENTS AND METHODS: Primary tumour samples were available for 1274 patients (27% of IES population). Only patients for whom the IHC4 score could be calculated (based on oestrogen receptor, progesterone receptor, HER2 and Ki67) were included in this analysis (N = 430 patients). The clinical score (C) was based on age, grade, tumour size and nodal status. The association of clinicopathological parameters, IHC4(+C) scores and treatment effect with time to distant recurrence-free survival (TTDR) was assessed in univariable and multivariable Cox regression analyses. A modified clinical score (PathIEscore) (N = 350) was also estimated. RESULTS: Our results confirm the prognostic importance of the original IHC4, alone and in conjunction with clinical scores, but no significant difference with treatment effects was observed. The combined IHC4 + Clinical PathIES score was prognostic for TTDR (P < 0.001) with a hazard ratio (HR) of 5.54 (95% CI 1.29 23.70) for a change from 1st quartile (Q1) to Q1-Q3 and HR of 15.54 (95% CI 3.70 65.24) for a change from Q1 to Q4. CONCLUSION: In the PathIES population, the IHC4 score is useful in predicting long-term relapse in patients who remain disease-free after 2-3 years. This is a first trial to suggest the extending use of IHC4+C score for prognostic indication for patients who have switched endocrine therapies at 2-3 years and who remain disease-free after 2-3 years. PMID- 29177607 TI - Building Healthy Start Grantees' Capacity to Achieve Collective Impact: Lessons from the Field. AB - Purpose While Healthy Start has emphasized the need for multi-sectorial community engagement and collaboration since its inception, in 2014 Healthy Start adopted Collective Impact (CI) as a framework for reducing infant mortality. This paper describes the development of a peer-focused capacity-building strategy that introduced key elements of CI and preliminary findings of Healthy Start grantees' progress with using CI as an approach to collaboration. Description The Collective Impact Peer Learning Networks (CI-PLNs) consisted of eight 90-min virtual monthly meetings and one face-to-face session that reviewed CI pre conditions and conditions. Evaluation sources included: a facilitated group discussion at the final CI-PLN exploring grantee CI and CAN accomplishments (n = 57); routine evaluations (n = 144 pre, 46 interim, and 40 post PLN) examining changes in knowledge and practices regarding CI; and post CI-PLN implementation, three in-depth interviews with grantees who volunteered to discuss their experience with CI and participation in the CI-PLN. Assessment CI-PLN participants reported increased knowledge and confidence in the application of CI. Several participants reported that the CI-PLN created a space for engaging in peer sharing challenges, successes, and best practices. Participants also reported a desire to continue implementing CI and furthering their learning. Conclusion The CI-PLNs met the initial goal of increasing Healthy Start grantees' understanding of CI and determining the initial focus of their efforts. By year five, the EPIC Center anticipates Healthy Start CANs will have a sustainable infrastructure in place that supports the established common agenda, shared measures, and ongoing and meaningful inclusion of community members.

AB - We examined predictors of mental health difficulties and wellbeing in caregivers of children with autism in the Pre-school Autism Communication Trial cohort in middle childhood (N = 104). Child's intellectual disability, daily living skills impairment, elevated emotional and behavioural difficulties, high educational level of caregiver and household income below the median significantly predicted caregivers' mental health difficulties, but autism severity, child communication skills and family circumstances did not. Lower caregiver mental wellbeing was predicted by elevated child emotional and behavioural difficulties. The need to support the mental health and wellbeing of caregivers of children with autism is discussed in light of the results. PMID- 29177608 TI - Identification of Educational Gaps Among Oncologists Who Manage Patients with Pancreatic Cancer. AB - INTRODUCTION: Pancreatic ductal adenocarcinoma (PDA) is associated with poor outcomes and presents oncologists with a myriad of clinical challenges. This study was conducted to assess oncologists' practice patterns and to identify the greatest areas of need for future PDA continuing medical education (CME) programs. METHODS: Case vignettes have been validated as an effective tool to assess how physicians approach and treat a wide array of diseases. In order to assess practice patterns for resectable, locally advanced unresectable, and metastatic PDA, an online case vignette survey was distributed to practicing medical oncologists. RESULTS: Responses from 150 US-practicing oncologists were analyzed, and several key opportunities for future CME programs were identified. For case 1 (patient with resectable PDA), 44% of oncologists did not select an evidence-based adjuvant chemotherapy regimen. For case 2 (patient with locally advanced PDA who develops metastases and neuropathy after first-line nab paclitaxel/gemcitabine followed by chemoradiation), 57% of oncologists did not select an evidence-based second-line chemotherapy regimen, and 35% selected a regimen containing oxaliplatin, a chemotherapeutic known to cause neuropathy. For case 3 (patient with a pancreatic mass and liver metastases), only 34% of oncologists recommended a biopsy, chest imaging, and liver function tests which should be standard of care assessments with this presentation. For all three cases, clinical trial referral was selected by fewer than 5% of respondents. CONCLUSIONS: This study identified appreciable discrepancies between oncologists' recommendations and standard evidence-based guidelines. Well-designed CME programs may help to bridge the educational gaps identified and improve adherence to practice guidelines. PMID- 29177609 TI - Disregulation of miR-216a and miR-217 in Gastric Cancer and Their Clinical Significance. AB - OBJECTIVE: The majority of gastric cancer (GC) diagnoses occur at the middle or late stage of the disease, indicating that finding novel biomarkers that could be detectable at earlier stage is urgently needed. Accumulating studies have shown that microRNAs, a class of tiny single-stranded RNAs, play important roles in multiple biological processes including cancer development. The present study aimed to evaluate the effect of miR-216a and miR-217 in GC. MATERIAL AND METHODS: The real-time quantitative reverse-transcription PCR was exploited to identify and compare the expression levels of miR-216a and miR-217 in 37 pairs of samples of gastric cancer tissue and adjacent normal tissue. Superimposed on this, the potential relationship between miR-216a/217 levels and clinicopathological parameters in patients suffering GC was explored. RESULTS: The results obtained from this study showed that the miR-216a is significantly upregulated in gastric cancer tissues, compared with adjacent normal tissues, but the altered expression of miR-217 was not significant. For miR-216a/217, no significant correlations were detected between expression levels of these miRNAs and clinical and pathological characteristics of patients. CONCLUSION: This prospective study proposes that upregulation of miR-216a might represent an important mechanism for the development of gastric cancer. PMID- 29177610 TI - Findings from an outbreak of carbapenem-resistant Klebsiella pneumoniae emphasize the role of antibiotic treatment for cross transmission. AB - PURPOSE: In January 2015, we noticed by rectal swab analyses that seven of 23 patients at an early rehabilitation ward had been colonized with carbapenem resistant Klebsiella pneumoniae (CKP). Here, we describe risk factors for CKP acquisition. METHODS: In the present study, the outbreak is described and risk factors for CKP acquisition are examined, e.g., antibiotic treatment. Microbiological analyses including corresponding results were examined to study when colonization with CKP occurred and whether patients had suffered from diarrhea. To examine whether spread of bacteria was clonal, multi-locus sequence typing as well as Xbal macrorestriction and pulsed-field gel electrophoresis was performed. The presence of carbapenmase was examined by PCR analysis. Through univariate analysis of risk factors in the small study sample, the role of antibiotic consumption, isolation procedures, patient's age, gender, and Barthel index on colonization was elucidated. RESULTS: Clonal spread of the novel sequence type (ST)2255 was identified. Additionally, one patient was colonized with Escherichia coli and Serratia marcescens, both resistant to carbapenems, while a further patient carried another carbapenem-resistant E. coli strain. In all isolates, carbapenemase gene bla OXA-48 was found to be located on a conjugative plasmid (60 kb), suggesting in vivo transmission from CKP to E. coli and S. marcescens. Univariate tests indicated that antibiotic treatment was the only risk factor showing a significant association with being colonized by CKP. In addition, the likelihood of diarrhea appeared to be higher in this group. Antibiotic treatment was associated with CKP colonization, whereas patients' age, gender, Barthel index at admission, and residence with a CKP-colonized roommate were not. Diarrhea also seemed to support to distribution of CKP. CONCLUSIONS: In this small outbreak, antibiotic treatment seemed to be the predominant risk factor for monoclonal transmission of bla OXA-48 positive CKP. PMID- 29177611 TI - Appropriate non-carbapenems are not inferior to carbapenems as initial empirical therapy for bacteremia caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae: a propensity score weighted multicenter cohort study. AB - The efficacy of empirical non-carbapenem antibiotics for extended-spectrum beta lactamase-producing Enterobacteriaceae bacteremia (ESBL-B) is still inconclusive. We conducted a multicenter retrospective cohort study to evaluate the efficacy of empirical non-carbapenem antibiotics for treating ESBL-B. Electronic medical records of individuals who were diagnosed with ESBL-B were reviewed between January 2010 and December 2014 at four university hospitals in Korea. Patients were classified into non-carbapenem and carbapenem groups according to the empirical antibiotic regimen. Patients treated with appropriate empirical antibiotics and who subsequently received carbapenems as definitive therapy were included in the analysis. The inverse probability of treatment weights, a statistical method that adjusts baseline statistics by giving weights based on propensity score, was used. During the study period, 232 adequately treated patients with ESBL-B were included in the analysis: 49 patients in the non carbapenem group and 183 in the carbapenem group. The baseline characteristics and severity of infection were similar after propensity score weighting. The 30 day mortality rates for the two groups were not statistically significantly different (non-carbapenems 6.3% and carbapenems 11.4%; P = 0.42). In a multivariate analysis, empirical treatment with non-carbapenem antibiotics was not associated with 30-day all-cause mortality (HR 1.02, 95% CI 0.99-1.06, P = 0.14). In a subgroup analysis, empirical treatment with piperacillin-tazobactam was also not associated with 30-day all-cause mortality (HR 1.21, 95% CI 0.37 4.00, P = 0.75). Appropriate non-carbapenems were not inferior to carbapenems as initial empirical therapy for ESBL-B. PMID- 29177612 TI - Evaluation of colistin stability in agar and comparison of four methods for MIC testing of colistin. AB - Susceptibility testing for colistin remains challenging primarily due to its inherent properties. We evaluated colistin stability in agar and reproducibility of colistin MICs obtained by agar dilution, broth macro- and micro-dilution and MIC gradient strips on 3-7 iterations of each method using clinical Klebsiella pneumoniae (susceptible-CS, and resistant-CR, n = 2 each), mcr-harboring Escherichia coli (n = 2), and reference strains E. coli ATCC25922 and Pseudomonas aeruginosa ATCC27853. MICs for reference strains were not in the given range using Etest and broth microdilution (ATCC25922, 0.125 and 4 MUg/ml, respectively). MICs of CR-1 and CR-2, and of the mcr-harboring E. coli showed high concordance between agar and broth dilution varying up to one 2-fold dilution. However, remarkable variations were observed on broth dilution with CS 1 and CS-2 (MIC range 0.25-32 and 0.5-64 MUg/ml, respectively); whereas for agar dilution the MIC for both CS strains was 0.5 MUg/ml in all the runs. MICs obtained by MIC gradient strips were lower than those obtained by dilution methods (1-2 dilutions for CS and mcr strains, and up to five dilutions for CR strains). To confirm uniform distribution of colistin in agar, a single strain was spotted in five different regions of the same plate. All spots showed concordant growth with maximum one dilution difference. No effect on MIC was found due to storage of colistin-containing agar plates for 7 days at 4 degrees C. In our hands, agar dilution was superior in terms of reproducibility and robustness, compared to broth dilution methods, for colistin MIC determination. PMID- 29177614 TI - The quality of information on the internet relating to top-selling dietary supplements in the Czech Republic. AB - Background The purchase of dietary supplements (DS) via the Internet is increasing worldwide as well as in the Czech Republic. Objective The aim of the study is to evaluate the quality of information on DS available on the Internet. Setting Czech websites related to dietary supplements. Methods A cross-sectional study was carried out involving the analysis of information placed on the websites related to the 100 top-selling DS in the Czech Republic in 2014, according to IMS Health data. Main outcome measure The following criteria were evaluated: contact for the manufacturer, recommended dosage, information on active substances as well as overall composition, permitted health claims, % of the daily reference intake value (DRIV) for vitamins and minerals, link for online counseling, pregnancy/breastfeeding, allergy information, contraindications, adverse reactions, and supplement-drug interactions (some criteria were evaluated from both points of view). Results A total of 199 web domains and 850 websites were evaluated. From the regulatory point of view, all the criteria were fulfilled by 11.3% of websites. Almost 9% of the websites reported information referring to the treatment, cure, or prevention of a disease. From the clinical point of view, all the criteria were only met by one website. Conclusions The quality of information related to DS available on the Internet in the Czech Republic is quite low. The consumers should consult a specialist when using DS purchased online.

AB - Omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) are necessary for functional cell integrity. Preconditioning (PC), as we define it, is an acquired protection or resilience by a cell, tissue, or organ to a lethal stimulus enabled by a previous sublethal stressor or stimulus. In this study, we provide evidence that the omega-3 fatty acid docosahexaenoic acid (DHA) and its derivatives, the docosanoids 17-hydroxy docosahexaenoic acid (17-HDHA) and neuroprotectin D1 (NPD1), facilitate cell survival in both in vitro and in vivo models of retinal PC. We also demonstrate that PC requires the enzyme 15-lipoxygenase-1 (15-LOX-1), which synthesizes 17-HDHA and NPD1, and that this is specific to docosanoid signaling despite the concomitant release of the omega-6 arachidonic acid and eicosanoid synthesis. These findings advocate that DHA and docosanoids are protective enablers of PC in photoreceptor and retinal pigment epithelial cells.

AB - ETV6-ABL1 fusion is a rare but recurrent oncogenic lesion found in childhood B cell precursor acute lymphoblastic leukemia (BCP-ALL), without an established chromosomal abnormality, and is associated with poor outcome. In ETV6-ABL1 positive cases, an in-frame fusion produced by a complex rearrangement results in constitutive chimeric tyrosine kinase activity. Monosomy 7 is also a rare and unfavorable chromosomal abnormality in childhood BCP-ALL. Here, we report a 14 year-old female BCP-ALL patient with ETV6-ABL1 fusion combined with monosomy 7. She was admitted to our hospital because of persistent fever. Bone marrow nuclear cell count on admission was 855,000/uL with 90.0% blastic cells of lymphoid morphology. Blasts were positive for CD10, CD19, CD20, CD34, cyCD79a, cyTdT, HLA DR, and CD66c, had a karyotype of 45, XX, - 7 [18/20] and a split signal for ABL1 FISH probe (92.7%), and were sensitive to tyrosine kinase inhibitors, imatinib and dasatinib, in vitro. ETV6-ABL1 fusion transcript was identified by whole transcriptome sequencing and confirmed by RT-PCR. She was treated with the high risk protocol based on ALL-BFM 95, achieved complete remission (CR) after induction chemotherapy, and maintained CR for 4 months. To our knowledge, this is the first report of ETV6-ABL1 fusion combined with monosomy 7 in childhood BCP ALL. PMID- 29177617 TI - Do Parents Model Gestures Differently When Children's Gestures Differ? AB - Children with autism spectrum disorder (ASD) or with Down syndrome (DS) show diagnosis-specific differences from typically developing (TD) children in gesture production. We asked whether these differences reflect the differences in parental gesture input. Our systematic observations of 23 children with ASD and 23 with DS (Mages = 2;6)-compared to 23 TD children (Mage = 1;6) similar in expressive vocabulary-showed that across groups children and parents produced similar types of gestures and gesture-speech combinations. However, only children but not their parents-showed diagnosis-specific variability in how often they produced each type of gesture and gesture-speech combination. These findings suggest that, even though parents model gestures similarly, the amount with which children produce each type largely reflects diagnosis-specific abilities. PMID- 29177618 TI - Parent-Implemented Bedtime Fading and Positive Routines for Children with Autism Spectrum Disorders. AB - Sleep disorders affect a large portion of those with autism spectrum disorder. Behavioural interventions have been found to increase appropriate sleep behaviours. This study sought to examine the efficacy of two stimulus control interventions (bedtime fading and positive routines) on total sleep duration, sleep onset latency and frequency and duration of night wakings for children with autism using two multiple baseline designs. Secondary dependent variables, namely, educational opportunities, challenging behaviours, parent acceptance and social validity were also analysed. Results suggest some efficacy for both interventions. Increased total sleep duration and decreased sleep onset latency were achieved with bedtime fading. Positive routines showed mixed results with decreased sleep onset latency and increased total sleep duration for two of three participants. PMID- 29177616 TI - Medial Frontal Lobe Neurochemistry in Autism Spectrum Disorder is Marked by Reduced N-Acetylaspartate and Unchanged Gamma-Aminobutyric Acid and Glutamate + Glutamine Levels. AB - The nature of neurochemical changes in autism spectrum disorder (ASD) remains controversial. We compared medial prefrontal cortex (mPFC) neurochemistry of twenty high-functioning children and adolescents with ASD without associated comorbidities and fourteen controls. We observed reduced total N-acetylaspartate (tNAA) and total creatine, increased Glx/tNAA but unchanged glutamate + glutamine (Glx) and unchanged absolute or relative gamma-aminobutyric acid (GABA+) in the ASD group. Importantly, both smaller absolute and relative GABA+ levels were associated with worse communication skills and developmental delay scores assessed by the autism diagnostic interview-revised (ADI-R). We conclude that tNAA is reduced in the mPFC in ASD and that glutamatergic metabolism may be altered due to unbalanced Glx/tNAA. Moreover, GABA+ is related to autistic symptoms assessed by the ADI-R.

PMID- 29177620 TI - Revisiting traumatic cardiac arrest: should CPR be initiated? AB - OBJECTIVES: Traumatic cardiac arrest (TCA) represents a unique problem, and poses difficult challenges in the care of trauma patients. Although the literature has suggested that attempted resuscitation from TCA in trauma is futile and consumptive of medical and human resources, studies have recently demonstrated that the outcome of TCA is comparable cardiac arrest secondary to non-traumatic events. The objective of this study was to determine the incidence, predictors, and outcomes following TCA. METHODS: We retrospectively reviewed 124 adult patients with TCA over a period of 5 years (July 2010 to June 2014). Cardiopulmonary resuscitation (CPR) occurred either in the field, en route, or in the emergency department at our Level I Trauma Center. Patients' demographics, clinical data, CPR-related variables, and outcomes were extracted from both the electronic and paper medical records. RESULTS: The median age of the group was 37 (IQR 38), and the median ISS was 37 (IQR 50). The most common cardiac rhythm observed was pulseless electrical activity (PEA, 55%). While 31.4% of patients achieved a return of spontaneous circulation (ROSC), only 7.3% survived with a complete neurological recovery (CNR). In blunt injury patients, the mortality rate after CPR was higher in motor-vehicle-related injuries than falls from heights (93.1 vs 72.3%, OR 5.06, 95% CI 0.95-27.0, p < 0.05). In penetrating injuries, the mortality rate after CPR was higher in patients with trauma to the torsos than those suffering injuries to the head, neck, face, and extremities combined (100 vs 81.3%, OR 0.049, 95% CI 0.0024-1.008, p < 0.001). Two variables predicted failure of CPR were prolonged time interval hospital transport (OR 0.42, 95% CI 0.22-0.80, p < 0.01) and high injury severity score (OR 0.97, 95% CI 0.94-1.00, p < 0.05). However, CPR duration/location (out-of-hospital or in hospital), head injury, and day/night shifts in ED were not associated with the above outcome. When comparing age groups, the mortality was significantly higher in patients < 65 years than those >= 65 years (OR 0.2619, 95% CI 0.09485-0.9703, p = 0.0182). CONCLUSION: Although survival after CPR among trauma patients continues to have dismal outcomes, advanced cardiac life support should be initiated regardless of the initial EKG rhythm. Ultimately, both a rapid response time and transport to the ED are of the utmost importance to survival. PMID- 29177623 TI - Expression of single-domain antibody in different systems. AB - Camelid single-domain antibodies (sdAbs, VHHs, or Nanobodies(r)) are types of antibody fragments that are composed of the heavy-chain variable domain only. These VHHs possess unique structural and functional features, as they are small in size and exhibit thermal stability and high solubility. Compared to conventional antibodies, VHHs can be manufactured in microorganisms to significantly save on cost, labor, and time since VHHs lack the Fc domain with its N-linked oligosaccharide. Until now, VHHs have been expressed in several kinds of production systems, ranging from prokaryotic cells, yeasts, fungi, insect cells, and mammalian cell lines, to plants. In this review, we focus on the recent production of VHHs, introduce different platforms, and summarize the current state of this area and its future trends. Finally, the first potential VHH product, produced in Pichia pastoris, will probably be available on the market in 2018; thus, it is of great importance to give this antibody fragment timely attention. This is the first review concerning the production of VHHs in laboratory settings. PMID- 29177624 TI - Production of Monascus pigments as extracellular crystals by cell suspension culture. AB - It is generally accepted that Monascus pigments are predominantly cell-bound, including both intracellular and surface-bound pigments. This long-term misconception was corrected in the present work. Production of extracellular crystal pigments by submerged culture of Monascus sp. was confirmed by microscopic observation and collection of Monascus pigments from extracellular broth by direct membrane filtration. Following up the new fact, the bioactivity of mycelia as whole-cell biocatalyst for biosynthesis and biodegradation of Monascus pigments had been detailedly examined in both an aqueous solution and a nonionic surfactant micelle aqueous solution. Based on those experimental results, cell suspension culture in an aqueous medium was developed as a novel strategy for accumulation of high concentration of Monascus pigments. Thus, glucose feeding during submerged culture in the aqueous medium was carried out successfully and high orange Monascus pigments concentration of near 4 g/L was achieved. PMID- 29177625 TI - Hydrometrocolpos etiology and management: past beckons the present. AB - Hydrometrocolpos is a rare condition in which the uterus and the vagina are grossly distended with a retained fluid other than pus or blood. It may present during the neonatal period or later at puberty. Most cases reported earlier were stillbirths and were diagnosed only on autopsy. Antenatal diagnosis is now possible with the advent of ultrasound. An early diagnosis and speedy management is the key to survival. Many previous case reports have focused on the varied clinical presentations, multiple causes, associated syndromes and/or the radiological diagnosis of this condition. However, management options for different types of hydrometrocolpos have not yet been concisely discussed. We have reviewed the literature and tried to summarize the management options applicable to most case scenarios of hydrometrocolpos. PMID- 29177627 TI - Virtual 3D planning of tracheostomy placement and clinical applicability of 3D cannula design: a three-step study. AB - AIM: We aimed to investigate the potential of 3D virtual planning of tracheostomy tube placement and 3D cannula design to prevent tracheostomy complications due to inadequate cannula position. MATERIALS AND METHODS: 3D models of commercially available cannula were positioned in 3D models of the airway. In study (1), a cohort that underwent tracheostomy between 2013 and 2015 was selected (n = 26). The cannula was virtually placed in the airway in the pre-operative CT scan and its position was compared to the cannula position on post-operative CT scans. In study (2), a cohort with neuromuscular disease (n = 14) was analyzed. Virtual cannula placing was performed in CT scans and tested if problems could be anticipated. Finally (3), for a patient with Duchenne muscular dystrophy and complications of conventional tracheostomy cannula, a patient-specific cannula was 3D designed, fabricated, and placed. RESULTS: (1) The 3D planned and post operative tracheostomy position differed significantly. (2) Three groups of patients were identified: (A) normal anatomy; (B) abnormal anatomy, commercially available cannula fits; and (C) abnormal anatomy, custom-made cannula, may be necessary. (3) The position of the custom-designed cannula was optimal and the trachea healed. CONCLUSIONS: Virtual planning of the tracheostomy did not correlate with actual cannula position. Identifying patients with abnormal airway anatomy in whom commercially available cannula cannot be optimally positioned is advantageous. Patient-specific cannula design based on 3D virtualization of the airway was beneficial in a patient with abnormal airway anatomy. PMID- 29177626 TI - Non-surgical treatment of obstructive sleep apnea syndrome. AB - Obstructive sleep apnea syndrome (OSAS), a pervasive disease, is closely associated with complications such as cardiovascular diseases, neurocognitive diseases, and metabolic syndromes. Continuous positive airway pressure (CPAP) is the standard treatment for OSAS, with low compliance due to multifarious factors. The two other modes of ventilation, bi-level positive airway pressure (BPAP) and autotitrating positive airway pressure (APAP), which were developed from CPAP, are slightly different from CPAP in specific groups, as well as the corresponding treatment effect and compliance. The compliance of traditional positional therapy is not high, but with the emergence of the neck-based position treatment device, its compliance and indications have changed. Although CPAP is superior to mandibular advancement device (MAD) in improving AHI, MAD seems to be comparable to CPAP in improving other indicators. Corticosteroids and leukotriene receptor antagonists are effective treatments for mild OSAS children. Whether corticosteroids can be used in other OSAS groups and their adjunctive functions to CPAP remains unclear. The combination of these two kinds of drugs appears to be more effective than single drug. Researches on transcutaneous electrical stimulation are still not enough. Its effectiveness and stimulation settings still need further study. This review summarized the various OSAS non-surgical treatments from indications, treatment outcomes, compliance, adverse reactions, and recent progress. PMID- 29177628 TI - Mycophenolate mofetil following glucocorticoid treatment in Henoch-Schonlein purpura nephritis: the role of early initiation and therapeutic drug monitoring. AB - BACKGROUND: Henoch-Schonlein purpura (HSP) is the most common vasculitis in childhood and traditionally considered as a self-limiting disease. However, renal involvement can unfavorably determine long-term prognosis. The reported regimens to treat HSP nephritis (HSPN) are diverse, indicating that the most effective treatment remains controversial. METHODS: This retrospective, single-center study involved 18 patients presenting with HSPN and nephrotic-range proteinuria. We aimed to investigate the efficacy and safety of mycophenolate mofetil (MMF) and identify a cut-off level for estimated mycophenolic acid area under the curve (eMPA-AUC0-12h) values, which can predict complete remission with high sensitivity. RESULTS: Despite prior insufficient therapeutic response to corticosteroids, 89% of patients showed a significant decrease in proteinuria after 1 month of MMF treatment. None of them relapsed during treatment; however, two children relapsed after discontinuation. Based on results of a receiver operating characteristic (ROC) analysis, an eMPA-AUC0-12h >56.4 mg*h/l was a predictor for complete remission within 3 months (80% sensitivity, 83.3% specificity, p = 0.035). During MMF administration, we encountered no adverse event requiring discontinuation of treatment. CONCLUSION: Our study demonstrates that MMF is a safe and potentially effective secondary treatment option for children with HSPN to achieve and maintain long-term remission without serious side effects. To achieve complete remission within 3 months, resolve severe inflammatory glomerular lesions, and avoid progression to chronic kidney disease, we propose timely diagnosis and early initiation of MMF with an eMPA-AUC0-12h value of 56.4 mg*h/l.

AB - A great concern exists about the lifetime, cost, low-temperature performance, and safety of Li-ion batteries. Na-ion batteries (NIB) are an alternative to the Li ion batteries due to the wide availability of sodium, its low cost, and nontoxicity. Here, we examined the Na and Na+ adsorption on nanosheets of carbon (graphene), AlN, BN, and SiC to explore their potential use as an anode in NIBs. The interaction of atomic Na was found to play the main role in producing different nanosheet cell voltages. Unlike the graphene and SiC nanosheets, the lone pairs on the surface of the AlN and BN nanosheets hinder the Na adsorption and significantly increase the cell voltage. The order of magnitude of the nanosheet cell voltage as an anode in NIBs is as follows: AlN (1.49 V) > BN (1.46 V) > > C (0.69 V) > SiC (0.61 V). The AlN and BN nanosheets may be appropriate compounds for NIBs and their cell voltages are comparable with carbon nanotubes. PMID- 29177630 TI - Intraoperative monitoring of sensory part of the trigeminal nerve using blink reflex during microvascular decompression for trigeminal neuralgia. AB - Intraoperative monitoring during cerebellopontine angle surgery is widely accepted. While techniques which monitor cranial motor nerves are commonly used, monitoring the sensory afferents has been challenging. Considering the reflex arc, blink reflex (BR) might be useful in monitoring the sensory part of the trigeminal nerve, the brainstem connections and the facial nerve. We describe the case of a patient who developed hemifacial hypoesthesia after microvascular decompression surgery for trigeminal neuralgia. Intraoperative BR showed a severe loss of R1 amplitude. BR might be a useful intraoperative technique to monitor the sensory part of the trigeminal nerve. PMID- 29177631 TI - Manipulating an internal pulse generator until twiddler's syndrome in a patient treated with deep brain stimulation for obsessive-compulsive disorder. AB - BACKGROUND: Twiddler's syndrome consists of rotation or manipulation of an implantable pulse generator (IPG) in its subcutaneous pocket by a patient, thus causing hardware malfunction. METHODS: This syndrome is being reported more frequently in patients treated with deep brain stimulation (DBS). RESULTS: We report the case of a woman who had received bed nucleus of stria terminalis (BNST) electrodes for obsessive-compulsive disorder (OCD) and developed twiddler's syndrome a few months after surgery, causing hardware malfunction due to obsessive manipulation of the IPG. CONCLUSION: The patient did not have compulsions related to touching objects at admission, thus making it difficult to foresee and prevent TS. PMID- 29177632 TI - The use of lumbar epidural injection of platelet lysate for treatment of radicular pain. AB - BACKGROUND: Epidural steroid injections (ESI) are the most common pain management procedure performed in the US, however evidence of efficacy is limited. In addition, there is early evidence that the high dose of corticosteroids used can have systemic side effects. We describe the results of a case series evaluating the use of platelet lysate (PL) epidural injections for the treatment of lumbar radicular pain as an alternative to corticosteroids. METHODS: Registry data was obtained for patients (N = 470) treated with PL epidural injections presenting with symptoms of lumbar radicular pain and MRI findings that were consistent with symptoms. Collected outcomes included numeric pain score (NPS), functional rating index (FRI), and a modified single assessment numeric evaluation (SANE) rating. RESULTS: Patients treated with PL epidurals reported significantly lower (p < .0001) NPS and FRI change scores at all time points compared to baseline. Post treatment FRI change score means exceeded the minimal clinically important difference beyond 1 month. Average modified SANE ratings showed 49.7% improvement at 24 months post-treatment. Twenty-nine (6.3%) patients reported mild adverse events related to treatment. CONCLUSION: Patients treated with PL epidurals reported significant improvements in pain, exceeded the minimal clinically important difference (MCID) for FRI, and reported subjective improvement through 2-year follow-up. PL may be a promising substitute for corticosteroid. PMID- 29177633 TI - Osteoporosis is associated with increased risk for benign paroxysmal positional vertigo: a nationwide population-based study. AB - : Recent evidence has indicated that osteoporosis is a risk factor for benign paroxysmal positional vertigo (BPPV). This large population-based study demonstrated that patients with osteoporosis had a 1.82-fold higher risk of developing BPPV than those without osteoporosis through the use of the Taiwan National Health Insurance Research Database. PURPOSE: Benign paroxysmal positional vertigo (BPPV) is one of the most frequent causes of vertigo. Osteoporosis reflects a homeostatic imbalance in the rate of bone turnover, with the rate of bone resorption exceeding that of bone formation. Recent evidence has indicated that osteoporosis is a risk factor for BPPV. We aimed to validate the risk of BPPV in osteoporotic patients through a nationwide, population-based, cohort study. METHODS: Patients treated for osteoporosis were identified from entries made in the Taiwan National Health Insurance Research Database (NHIRD) between 2000 and 2013. Each osteoporosis patient was age- and sex-matched with four randomly selected subjects without osteoporosis. We compared the incidence rates of BPPV in the two cohorts (with and without osteoporosis) and identified risk factors. RESULTS: We identified 6649 osteoporosis patients and 26,596 match controls. According to the incidence of BPPV among the two groups, patients with osteoporosis were found to have a 1.82-fold higher risk of developing BPPV than those without osteoporosis. The incidence rate ratio (IRR) between osteoporotic patients and the control cohort was 2.0 (p < 0.001). CONCLUSIONS: This large population-based study demonstrated that patients with osteoporosis were associated with an increased risk for BPPV. The results of this study provide some insight into the management of BPPV. PMID- 29177634 TI - Endoscopic ultrasound (EUS) elastography and contrast enhanced EUS in groove pancreatitis.

PMID- 29177635 TI - The ArlRS two-component system is a regulator of Staphylococcus aureus-induced endothelial cell damage. AB - Staphylococcus aureus endovascular infections retain a high morbidity and mortality despite antibiotics and supportive care. The destruction of endothelial cells (ECs) is a critical step in the pathogenesis of S. aureus endovascular infections. In order to better understand S. aureus-induced EC damage, we systematically screened a collection of two-component regulatory system mutants of methicillin-resistant S. aureus (MRSA) USA300 strain JE2 for damage induction in human umbilical vein ECs (HUVECs). This screen revealed that the two-component regulatory system ArlRS is required for maximum damage: arlRS inactivation leads to a > 70% reduction in damage. In a different genetic S. aureus background (RN6390, MSSA strain) arlRS inactivation had a smaller but also significant effect on EC damage. In both strains, the reduction in EC damage was accompanied by a significant reduction in internalization. In conclusion, we determined a novel role of ArlRS in S. aureus-induced EC damage, which will help to better understand the pathogenesis of S. aureus endovascular infection. PMID- 29177636 TI - Sequence Analysis and Comparative Bioinformatics Study of Camelysin Gene (calY) Isolated from Bacillus thuringiensis. AB - Bacillus strains have been widely used for the production of fibrinolytic enzymes having role in the treatment of cardiovascular disorders. Purification and overproduction of such enzymes has increased their usage in medical fields including metalloproteinases with the ability to degrade extracellular matrix (ECM). Camelysin, a neutral metalloproteinase has been isolated from different species of bacteria like Bacillus cereus, Bacillus anthracis, and Bacillus thuringiensis with fibrinolytic, collagenolytic and actin degradation activity. This project successfully demonstrated the presence of 734-bp coding DNA sequence (CDS) encoding a 20.72331 kDa camelysin gene in local strain of Bacillus thuringiensis containing a signal peptide with cleavage site between residues 19 and 20. The sequence was submitted to GenBank (KT023597) and the sequence showed high homology with the camelysin protein of closely related Bacillus species. The alignment of related proteins through ClustalW displayed difference of four amino acids ("Q" replaced by "P" at position 169 and at position 182-184, "NQE" replaced by "HLK") in the isolated protein. Comparison including structural and functional analysis of camelysin sequences isolated from different Bacillus species was carried out using different bioinformatics tools and software. The information would help in better understanding the properties of camelysin protein and its role in pathogenicity and clinical treatments. PMID- 29177637 TI - Inappropriate claims from non-equivalent medications in osteoarthritis: a position paper endorsed by the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO). AB - Osteoarthritis (OA) is a progressive joint disease, that occurs frequently in the aging population and is a major cause of disability worldwide. Both glucosamine and chondroitin are biologically active molecules that are substrates for proteoglycan, an essential component of the cartilage matrix. Evidence supports the use of glucosamine and chondroitin as symptomatic slow-acting drugs for osteoarthritis (SYSADOAs) with impact on OA symptoms and disease-modifying effects in the long term. Glucosamine and chondroitin are administered in exogenous form as a sulfate salt and multiple formulations of these agents are available, both as prescription-grade products and nutritional supplements. However, while all preparations may claim to deliver a therapeutic level of glucosamine or chondroitin not all are supported by clinical evidence. Only patented crystalline glucosamine sulfate (pCGS) is shown to deliver consistently high glucosamine bioavailability and plasma concentration in humans, which corresponds to demonstrated clinical efficacy. Similarly, clinical evidence supports only the pharmaceutical-grade chondroitin sulfate. The European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) advocates, through careful consideration of the evidence base, that judicious choice of glucosamine and chondroitin formulation is essential to maximize clinical benefit, patient adherence and satisfaction with treatment. In future, the ESCEO recommends that complex molecules with biological activity such as pCGS may be treated as "biosimilars" akin to the European Medicines Agency guidance on biological medicinal products. It seems likely that for all other complex molecules classed as SYSADOAs, the recommendation to use only formulations clearly supported by the evidence-base should apply. PMID- 29177638 TI - The Ferroxidase Hephaestin But Not Amyloid Precursor Protein is Required for Ferroportin-Supported Iron Efflux in Primary Hippocampal Neurons. AB - Iron efflux in mammalian cells is mediated by the ferrous iron exporter ferroportin (Fpn); Fpn plasma membrane localization and function are supported by a multicopper ferroxidase and/or the soluble amyloid precursor protein (sAPP). Fpn and APP are ubiquitously expressed in all cell types in the central nervous system including neurons. In contrast, neuronal ferroxidase(s) expression has not been well characterized. Using primary cultures of hippocampal neurons, we examined the molecular mechanism of neuronal Fe efflux in detail. Developmental increases of Fpn, APP, and the ferroxidase hephaestin (Hp) were observed in hippocampal neurons. Iron efflux in these neurons depended on the level of Fpn localized at the cell surface; as noted, Fpn stability is supported by ferroxidase activity, an enzymatic activity that is required for Fe efflux. Iron accumulation increases and iron efflux decreases in Hp knockout neurons. In contrast, suppression of endogenous APP by RNAi knockdown does not affect surface Fpn stability or Fe efflux. These data support the model that the neuronal ferroxidase Hp plays a unique role in support of Fpn-mediated Fe efflux in primary hippocampal neurons. Our data also demonstrate that Hp ferroxidase activity relies on copper bioavailability, which suggests neuronal iron homeostasis will be modulated by cellular copper status. PMID- 29177639 TI - Referential and Non-referential Uses of the Third Person Pronominal Subject in Spanish. AB - This paper studies the role of two different types of motivation that have been proposed to explain the use of subject personal pronouns in Spanish, namely their function as indications for the addressee to identify the subject's referent, and their suitability for expressing informational values such as contrastiveness or focus. This study focuses exclusively on third-person forms and relies on conversational data. The distribution of third-person pronouns is analysed combining qualitative and quantitative approaches. It will be argued that the informational and referential properties of subject personal pronouns are by themselves insufficient to account for their expression, their occurrence depending crucially on their activation through the previous use of units of the same type. PMID- 29177640 TI - Heat stress alters genome-wide profiles of circular RNAs in Arabidopsis. AB - KEY MESSAGE: 1599 novel circRNAs and 1583 heat stress-specific circRNAs were identified in Arabidopsis. Heat stress enhanced accumulation of circRNAs remarkably. Heat stress altered the sizes of circRNAs, numbers of circularized exons and alterative circularization events. A putative circRNA-mediated ceRNA networks under heat stress was established. Heat stress retards plant growth and destabilizes crop yield. The noncoding RNAs were demonstrated to be involved in plant response to heat stress. As a newly-characterized class of noncoding RNAs, circular RNAs (circRNAs) play important roles in transcriptional and post transcriptional regulation. A few recent investigations indicated that plant circRNAs were differentially expressed under abiotic stress. However, little is known about how heat stress mediates biogenesis of circRNAs in plants. Here, we uncovered 1599 previously-unknown circRNAs and 1583 heat-specific circRNAs, by RNA-sequencing and bioinformatic analysis. Our results indicated that much more circRNAs were expressed under heat stress than in control condition. Besides, heat stress also increased the length of circRNAs, the quantity of circularized exons, and alternative circularization events. Moreover, we observed a positive correlation between expression patterns of some circRNAs and their parental genes. The prediction of ceRNA (competing endogenous RNA) networks indicated that differentially-expressed circRNAs could influence expression of many important genes, that participate in response to heat stress, hydrogen peroxide, and phytohormone signaling pathways, by interacting with the corresponding microRNAs. Together, our observations indicated that heat stress had great impacts on the biogenesis of circRNAs. Heat-induced circRNAs might participate in plant response to heat stress through the circRNA-mediated ceRNA networks. PMID- 29177642 TI - Three coexisting lymphomas in a single patient: composite lymphoma derived from a common germinal center B-cell precursor and unrelated discordant lymphoma. AB - Composite lymphoma (CL) is a rare disorder defined as the coexistence of two or more distinct lymphoma subtypes at a single anatomic site. Discordant lymphoma (DL), which is the simultaneous occurrence of two or more distinct lymphoma subtypes at different sites, is also rare. CL complicated with DL involving three distinct subtypes of lymphoma in the same patient is an extremely rare disease. Clonal relationships in CL and DL are commonly investigated by molecular analysis using mutational status with t(14;18)BCL2/IgH translocation and immunoglobulin heavy chain variable-region (IgVH) gene rearrangement. A 73-year-old woman was admitted to our hospital with systemic lymphadenopathy and was initially diagnosed with diffuse large B-cell lymphoma based on pathological features of the biopsied esophageal tumor. However, the results of inguinal lymph node biopsy led to a revised pathological diagnosis CL consisting of Hodgkin lymphoma and follicular lymphoma. Three distinct coexisting lymphomas were identified in this individual patient. Molecular analysis revealed CL derived from common germinal center B-cell precursors, while clonal relationship between CL and DL was not clarified. This case suggests a mechanism underlying B-cell lymphoma pathogenesis involving two pivotal somatic mutations, t(14;18)BCL2/IgH translocation and IgVH rearrangement. PMID- 29177641 TI - Prolactinoma through the female life cycle. AB - Prolactinomas are the most common secretory pituitary adenoma. They typically occur in women in the 3rd-6th decade of life and rarely in the pediatric population or after menopause. Most women present with irregular menses and/or infertility. Dopamine (DA) agonists, used in their treatment, are safe during pregnancy, but in most cases are discontinued at conception with close monitoring for signs or symptoms of tumor growth. Breastfeeding is safe postpartum, provided there was no significant growth during pregnancy. Some women will experience normalization of prolactin levels postpartum. Menopause may also decrease prolactin levels and even those with macroprolactinomas may consider discontinuing their DA agonist with close follow-up. Prolactinomas may be associated with decreased quality of life scores in women, and play a role in bone health and cardiovascular risk factors. This review discusses the current literature and clinical understanding of prolactinomas throughout the entirety of the female life cycle. PMID- 29177643 TI - Iron overload in myelodysplastic syndromes (MDS). AB - Iron overload (IOL) starts to develop in MDS patients before they become transfusion-dependent because ineffective erythropoiesis suppresses hepcidin production in the liver and thus leads to unrestrained intestinal iron uptake. However, the most important cause of iron overload in MDS is chronic transfusion therapy. While transfusion dependency by itself is a negative prognostic factor reflecting poor bone marrow function, the ensuing transfusional iron overload has an additional dose-dependent negative impact on the survival of patients with lower risk MDS. Cardiac dysfunction appears to be important in this context, as a consequence of chronic anemia, age-related cardiac comorbidity, and iron overload. Another potential problem is iron-related endothelial dysfunction. There is some evidence that with increasing age, high circulating iron levels worsen the atherosclerotic phenotype. Transfusional IOL also appears to aggravate bone marrow failure in MDS, through unfavorable effects on mesenchymal stromal cells as well a hematopoietic cells, particularly erythroid precursors. Patient series and clinical trials have shown that the iron chelators deferoxamine and deferasirox can improve hematopoiesis in a minority of transfusion-dependent patients. Analyses of registry data suggest that iron chelation provides a survival benefit for patients with MDS, but data from a prospective randomized clinical trial are still lacking. PMID- 29177644 TI - Pharmacokinetic Analysis of Four Bioactive Iridoid and Secoiridoid Glycoside Components of Radix Gentianae Macrophyllae and Their Synergistic Excretion by HPLC-DAD Combined with Second-Order Calibration. AB - An HPLC-DAD method combined with second-order calibration based on the alternating trilinear decomposition (ATLD) algorithm with the aid of region selection was developed to simultaneously and quantitatively characterize the synergistic relationships and cumulative excretion of the four bioactive ingredients of Radix Gentianae Macrophyllae in vivo. Although the analytes spectra substantially overlapped with that of the biological matrix, the overlapping profiles between analytes and co-eluting interferences can be successfully separated and accurately quantified by the ATLD method on the basis of the strength of region selection. The proposed approach not only determined the content change but also revealed the synergistic relationships and the cumulative excretion in vivo of the four ingredients in urine and feces samples collected at different excretion time intervals. In addition, several statistical parameters were employed to evaluate the accuracy and precision of the method. Quantitative results were confirmed by HPLC-mass spectrometry. Satisfactory results indicated that the proposed approach can be utilized to investigate the pharmacokinetics of Radix Gentianae Macrophyllae excretion in vivo. PMID- 29177645 TI - Ledipasvir-Sofosbuvir for 8 Weeks in Non-Cirrhotic Patients with Previously Untreated Genotype 1 HCV Infection +/- HIV-1 Co-Infection. AB - : BACKGROUND AND OBJECTIVES: The efficacy of < 12 weeks of hepatitis C virus (HCV) treatment in patients co-infected with HCV and human immunodeficiency virus type 1 (HIV-1) has not been established. We assessed the efficacy and safety of ledipasvir-sofosbuvir for 8 weeks in HCV mono-infected and HCV/HIV-1 co-infected patients. METHODS: We enrolled patients mono-infected with genotype 1 HCV or co infected with HCV and HIV-1 who were HCV treatment-naive and did not have cirrhosis. HCV/HIV-1 co-infected patients were either not receiving antiretroviral treatment and had a CD4 T-cell count > 500 cells/mm3 or were receiving a protocol-approved antiretroviral regimen for >= 8 weeks (or >= 6 months for abacavir-containing regimens) and had HIV-1 RNA < 50 copies/mL and a CD4 T-cell count > 200 cells/mm3. Patients received ledipasvir-sofosbuvir (90/400 mg) once daily for 8 weeks. The primary efficacy endpoint was sustained virologic response 12 weeks after treatment discontinuation (SVR12). RESULTS: The SVR12 rate was 100% (67/67) for HCV mono-infected patients and 97% (57/59) for HCV/HIV 1 co-infected patients. Two patients relapsed by the week 4 post-treatment visit. Overall, the most common adverse events were headache (52%) and upper abdominal pain (26%). There were no serious adverse events or treatment discontinuations due to adverse events. No HCV/HIV-1 co-infected patients receiving antiretroviral treatment experienced HIV virologic rebound, and no clinically meaningful changes in CD4 T-cell counts were observed in any co-infected patient. CONCLUSIONS: Non cirrhotic, treatment-naive patients with genotype 1 HCV mono-infection and HCV/HIV-1 co-infection achieved high rates of SVR12 with 8 weeks of treatment with ledipasvir/sofosbuvir. ClinicalTrials.gov identifier: NCT02472886. PMID- 29177646 TI - Longitudinal patterns of potentially inappropriate prescribing in early old-aged people. AB - PURPOSE: It is contentious whether potentially inappropriate prescribing (PIP) is predominantly a phenomenon of late life or whether it has its origins in early old age. This study examined the pattern of PIP in an early old-aged population over 5 years. METHODS: Secondary data analysis of a population-based primary care cohort, of patients aged 60-74 years. Medication data were extracted from electronic patient records in addition to information on comorbidities and demographics. Explicit START criteria (PPOs) and STOPP criteria (PIMs) were used to identify PIP. Generalised estimating equations were used to describe trends in PIP over time and adjusted for age, gender and number of medicines. RESULTS: A total of 978 participants (47.8%) aged 60-74 years were included from the cohort. At baseline, PPOs were detected in 31.2% of patients and PIMs were identified in 35.6% at baseline. Prevalence of PPOs and PIMs increased significantly over time (OR 1.08, 95% CI 1.07; 1.09 and OR 1.04, 95% CI 1.0; 1.06, respectively). A higher number of medicines and new diagnoses were associated with the increasing trend in both PPO and PIM prevalence observed over time, independent of PPOs and PIMs triggered by drug combinations. CONCLUSIONS: Potentially inappropriate prescribing is highly prevalent among early old-aged people in primary care and increases as they progress to more advanced old age, suggesting that routine application of STOPP/START criteria in this population would significantly improve medication appropriateness. PMID- 29177647 TI - Targeted Deletion of Hsf1, 2, and 4 Genes in Mice. AB - Heat shock transcription factors (Hsfs) regulate transcription of heat shock proteins as well as other genes whose promoters contain heat shock elements (HSEs). There are at least five Hsfs in mammalian cells, Hsf1, Hsf2, Hsf3, Hsf4, and Hsfy (Wu, Annu Rev Cell Dev Biol 11:441-469, 1995; Morimoto, Genes Dev 12:3788-3796, 1998; Tessari et al., Mol Hum Repord 4:253-258, 2004; Fujimoto et al., Mol Biol Cell 21:106-116, 2010; Nakai et al., Mol Cell Biol 17:469-481, 1997; Sarge et al., Genes Dev 5:1902-1911, 1991). To understand the physiological roles of Hsf1, Hsf2, and Hsf4 in vivo, we generated knockout mouse lines for these factors (Zhang et al., J Cell Biochem 86:376-393, 2002; Wang et al., Genesis 36:48-61, 2003; Min et al., Genesis 40:205-217, 2004). Numbers of other laboratories have also generated Hsf1 (Xiao et al., EMBO J 18:5943-5952, 1999; Sugahara et al., Hear Res 182:88-96, 2003), Hsf2 (McMillan et al., Mol Cell Biol 22:8005-8014, 2002; Kallio et al., EMBO J 21:2591-2601, 2002), and Hsf4 (Fujimoto et al., EMBO J 23:4297-4306, 2004) knockout mouse models. In this chapter, we describe the design of the targeting vectors, the plasmids used, and the successful generation of mice lacking the individual genes. We also briefly describe what we have learned about the physiological functions of these genes in vivo. PMID- 29177648 TI - Role of Heat Shock Factors in Stress-Induced Transcription. AB - Heat shock proteins (HSP) are rapidly induced after stresses such as heat shock and accumulate at high concentrations in cells. HSP induction involves primarily a family of heat shock transcription factors (HSF) that bind the heat shock elements of the HSP genes and mediate transcription in trans. We discuss methods for the study of HSP binding to HSP promoters and the consequent increases in HSP gene expression in vitro and in vivo. PMID- 29177649 TI - Monitoring of the Heat Shock Response with a Real-Time Luciferase Reporter. AB - The heat shock response (HSR) is a cellular mechanism for counteracting acute proteotoxic stress. In eukaryotes, transcriptional activation of the HSR is regulated by heat shock factor 1 (HSF1). Activation of HSF1 induces the expression of heat shock proteins (HSPs) that function as molecular chaperones to fold and maintain the three-dimensional structure of misfolded proteins. The regulation of the degree and duration of the HSR is controlled by multiple biochemical mechanisms that include posttranslational modification of HSF1 and numerous protein-protein interactions. In this chapter, we describe a method to evaluate the activation and deactivation of the HSR at the transcriptional level using a short half-life luciferase reporter assay. This assay can be used to further characterize the HSR or as a screen for small-molecule inducers, amplifiers, or repressors. PMID- 29177650 TI - Quantitative Profiling of Chaperone/Client Interactions with LUMIER Assay. AB - Chaperones associate with hundreds or thousands of diverse client proteins and regulate their function. Chaperone/client interactions are generally very transient and involve a highly orchestrated assembly and disassembly of regulatory co-factors. This poses specific challenges for identifying and characterizing these interactions in a scalable and sensitive manner. LUMIER assay, which takes advantage of the high sensitivity and linear range of luminescence-based detection, has proven to be an ideal assay to quantitatively profile chaperone/client interactions in a high-throughput manner. This article provides step-by-step instructions for quantitatively profiling these interactions with LUMIER. PMID- 29177651 TI - Measurement of Chaperone-Mediated Effects on Polyglutamine Protein Aggregation by the Filter Trap Assay. AB - The formation of aggregates by polyglutamine-containing (polyQ) proteins in neurons is a key to the pathogenesis of several progressive neurodegenerative diseases such as Huntington's disease (HD) spinocerebellar ataxias (SCAs), and spinal and bulbar muscular atrophy (SBMA). In order to study whether the members of the heat shock protein (HSP) families, by virtue of their molecular chaperone activity, can inhibit the formation of polyQ aggregates, we developed a cell culture model expressing the GFP tagged fragment of exon1 of the huntingtin gene with an expanded polyQ chain and tetracycline inducible chaperones. Expression of mutated Huntington's protein leads to the formation of 2% SDS insoluble high molecular weight polyQ aggregates that are retarded on a cellulose acetate membrane in the so-called filter trap assay (FTA). This chapter explains in detail the protocols of the FTA and how it can be a useful tool to study the effect of HSPs or their functional mutants on aggregation of polyglutamine proteins. Moreover, the assay is useful to investigate how externally added polyQ peptides can act as nucleation seeds for internally expressed polyQ proteins. PMID- 29177652 TI - Fluorescent-Linked Enzyme Chemoproteomic Strategy (FLECS) for Identifying HSP70 Inhibitors. AB - Activation of the heat shock response, and in particular upregulation of stress inducible Hsp70, herein referred to as Hsp70i, in newly transformed cells, appears to protect against protein damaging stimuli, induction of premature oncogene-induced terminal senescence (OIS), and apoptosis, thereby enabling tumor initiation and progression to an aggressive phenotype. Expressed at very low or undetectable levels in normal tissue, the cytoprotective effects of Hsp70i appear to be mediated through its activity as a molecular chaperone allowing proper folding of mutated proteins, and by blocking cell signaling pathways that regulate OIS and apoptosis. Identification of small-molecule inhibitors selective for Hsp70i could provide new therapeutic tools for cancer treatment. However, identification of selective inhibitors of Hsp70i has proven challenging largely because of the affinity of the protein for ATP. Additionally, its chaperone functions do not lend the protein amenable to traditional enzymatic high throughput screens. Here, we describe the use of fluorescence-linked enzyme chemoproteomic strategy (FLECS) to identify Hsp70i inhibitors. The FLECS assay is a simple binding assay that enables proteins tagged with fluorophors to be rapidly and quantitative screened against small-molecule libraries. We show several case history examples of the methodology that led to the discovery of the Fatty acid synthase inhibitor, FASNALL, the DAPK3 inhibitor HS38, and HS72, an allosteric inhibitor selective for Hsp70i. PMID- 29177653 TI - A High-Throughput Screen for Inhibitors of the Hsp90-Chaperone Machine. AB - Hsp90 has emerged as a key chemotherapeutic target for the development of drugs for the treatment of cancer and neurodegenerative diseases. The shortcomings of many of the Hsp90 inhibitors that have made it to clinical trials have bolstered the need to identify new lead compounds with superior properties. Here, we describe a high-throughput screen for the identification of Hsp90 inhibitors based on the refolding of thermally denatured firefly luciferase. PMID- 29177654 TI - Primary Colorectal Cells Culture as a Translational Research Model. AB - Preclinical studies are an essential stage for any pharmacological agent hoping to make its way into clinical trials. An ideal preclinical model that can accurately predict clinical response does not exist and the best that the scientific community have at the moment is to select the most relevant study model pertaining to the disease of interest from those available, which includes: cell lines, animal models, and even in-silico methodology. Currently, there is a huge gap between preclinical and clinical trial results, indicating that there is much room for improvement in developing a better model to bridge the translational gap. PMID- 29177655 TI - Cell Death and Survival Assays. AB - Heat shock proteins are well-known protectors from cell death. Cell death (in particular, apoptosis and necrosis) is accompanied by certain hallmarks manifested as specific alterations in cellular membranes, cytoplasm, nucleus, and mitochondria. Some of those hallmarks are easily detectable in situ and, therefore, they can be applied for the assessment of dying or dead cells. In turn, there are also signs of viable cells that include such features as normal functioning of their membranes and organelles, ability to proliferate, etc. This chapter describes several convenient methods for quantification of dead (apoptotic and necrotic) cells as well as methods for assessment of viable cells. We describe in detail methods of annexin V/propidium iodide (PI) staining, TUNEL assay, Hoechst/PI staining, caspase activation, MTS tetrazolium, lactate dehydrogenase (LDH) release, colony formation, and senescence assays, with the principles, advantages, and drawbacks of each technique. PMID- 29177656 TI - Detecting the Potential Pharmacological Synergy of Drug Combination by Viability Assays In Vitro. AB - Heat shock protein 90 (HSP90) is a molecular chaperone necessary for the folding and proper function of multiple "client" proteins. HSP90 is involved in numerous biological processes and is critical to maintain proteostasis and to protect the cells from potentially harmful environmental stresses such as heat. However, in cancer, the role of HSP90, and other molecular chaperones, is corrupted as many of HSP90 clients are kinases and transcription factors whose aberrant activation or mutation drives tumor growth. Thus, developing a polytherapy, or combination therapy, that includes an HSP90 inhibitor in addition to targeting an oncogene or oncogenic pathway is an appealing therapeutic approach. This protocol will provide detailed methods on how to assess the potential synergy of polytherapy by viability assays in vitro. PMID- 29177657 TI - Proteomic Profiling of Hsp90 Inhibitors. AB - Mass spectrometry assays demonstrate that Hsp90 inhibitors alter the expression of approximately one-quarter of the assayable proteome in mammalian cells. These changes are extraordinarily robust and reproducible, making "proteomics profiling" the gold standard for validating the effects of new Hsp90 inhibitors on cultured cells. Proteomics assays can also suggest novel hypotheses regarding drug mechanisms. To assist investigators in adopting this approach, this Chapter provides detailed protocols for conducting simple proteomics assays of Hsp90 inhibition. The protocols present a robust label-free approach that utilizes pre fractionation of protein samples by SDS-PAGE, thereby providing reasonably good penetration into the proteome while addressing common issues with sample quality. The actual programming and operation of liquid chromatography-tandem mass spectrometers is not covered, but expectations for achievable performance are discussed, as are alternative approaches, common challenges, and software for data analysis. PMID- 29177658 TI - Analysis of HspB1 (Hsp27) Oligomerization and Phosphorylation Patterns and Its Interaction with Specific Client Polypeptides. AB - Human HspB1 (also denoted as Hsp27) belongs to the family of small (or stress) proteins (sHsps). The family, which contains ten members including alphaA,B crystallin polypeptides, is characterized by a conserved C-terminal alpha crystallin domain and molecular weights ranging from 20 to 40 kDa. Here, procedures are described for analyzing the dynamic oligomerization and phosphorylation patterns of HspB1 in cells exposed to different environments. Changes in the structural organization of HspB1 can reprogram its interaction with specific partner/client polypeptides. Methods are presented to analyze these interactions using tissue culture cells genetically modified to express different levels of this protein. In addition, the laboratory approaches presented here could be used to test the nine other human sHsp members as well as sHsps from other species. PMID- 29177659 TI - Nucleotide Exchange Factors for Hsp70 Chaperones. AB - The ATPase cycle of Hsp70 chaperones controls their transient association with substrates and thus governs their function in protein folding. Nucleotide exchange factors (NEFs) accelerate ADP release from Hsp70, which results in rebinding of ATP and release of the substrate, thereby regulating the lifetime of the Hsp70-substrate complex. This chapter describes several methods suitable to study NEFs of Hsp70 chaperones. On the one hand, steady-state ATPase assays provide information on how the NEF influences progression of the Hsp70 through the entire ATPase cycle. On the other hand, nucleotide release can be measured directly using labeled nucleotides, which enables identification and further characterization of NEFs. PMID- 29177660 TI - Determination of Hsp90 Activity Through Activation of Glucocorticoid Receptors in Yeast. AB - Heat shock protein 90 (Hsp90) is an essential regulator of cellular function through activation of so-called client proteins. Hsp90 is currently a target for potential anti-cancer therapeutics. Assaying for defects in Hsp90 using budding yeast (Saccharomyces cerevisiae) is possible and efficient due to the high conservation between the human and yeast Hsp90 systems. Here, we present a method for the determination of Hsp90 activity indirectly through the activation of exogenously expressed glucocorticoid receptor, a natural client protein of Hsp90. PMID- 29177661 TI - Bacterial Hsp90 ATPase Assays. AB - Bacterial Hsp90 is an ATP-dependent molecular chaperone involved in protein remodeling and activation. The E. coli Hsp90, Hsp90Ec, collaborates in protein remodeling with another ATP-dependent chaperone, DnaK, the E. coli Hsp70. Both Hsp90Ec and DnaK hydrolyze ATP and client (substrate) proteins stimulate the hydrolysis. Additionally, ATP hydrolysis by the combination of Hsp90Ec and DnaK is synergistically stimulated in the presence of client (substrate). Here, we describe two steady-state ATPase assays used to monitor ATP hydrolysis by Hsp90Ec and DnaK as well as the synergistic stimulation of ATP hydrolysis by the combination of Hsp90Ec and DnaK in the presence of a client (substrate). The first assay is a spectrophotometric assay based on enzyme-coupled reactions that utilize the ADP formed during ATP hydrolysis to oxidize NADH. The second assay is a more sensitive method that directly quantifies the radioactive inorganic phosphate released following the hydrolysis of [gamma-33P] ATP or [gamma-32P] ATP. PMID- 29177662 TI - Detecting Posttranslational Modifications of Hsp90. AB - The molecular chaperone Heat Shock Protein 90 (Hsp90) is essential in eukaryotes. Hsp90 chaperones proteins that are important determinants of multistep carcinogenesis. The chaperone function of Hsp90 is linked to its ability to bind and hydrolyze ATP. Co-chaperones as well as posttranslational modifications (phosphorylation, SUMOylation, and ubiquitination) are important for its stability and regulation of the ATPase activity. Both mammalian and yeast cells can be used to express and purify Hsp90 and also detect its posttranslational modifications by immunoblotting. PMID- 29177663 TI - Chromatin Immunoprecipitation (ChIP) of Heat Shock Protein 90 (Hsp90). AB - Chromatin immunoprecipitation followed by sequencing (ChIP-seq) is a widely used technique for genome-wide mapping of protein-DNA interactions and epigenetic marks in vivo. Recent studies have suggested an important role of heat shock protein 90 (Hsp90) at chromatin. This molecular chaperone assists other proteins to acquire their mature and functional conformation and helps in the assembly of many complexes. In this chapter, we provide specific details on how to perform Hsp90 ChIP-seq from Drosophila Schneider (S2) cells. Briefly, the cells are simultaneously lyzed and reversibly cross-linked to stabilize protein-DNA interactions. Chromatin is prepared from isolated nuclei and sheared by sonication. Hsp90-bound loci are immunoprecipitated and the corresponding DNA fragments are purified and sequenced. The described approach revealed that Hsp90 binds close to the transcriptional start site of around one-third of all Drosophila coding genes and characterized the role of the chaperone at chromatin. PMID- 29177664 TI - A Workflow Guide to RNA-seq Analysis of Chaperone Function and Beyond. AB - RNA sequencing (RNA-seq) is a powerful method of transcript analysis that allows for the sequence identification and quantification of cellular transcripts. RNA seq has many applications including differential gene expression (DE) analysis, gene fusion detection, allele-specific expression, isoform and splice variant quantification, and identification of novel genes. These applications can be used for downstream systems biology analyses such as gene ontology analysis to provide insights into cellular processes altered between biological conditions. Given the wide range of signaling pathways subject to chaperone activity as well as numerous chaperone functions in RNA metabolism, RNA-seq may provide a valuable tool for the study of chaperone proteins in biology and disease. This chapter outlines an example RNA-seq workflow to determine differentially expressed (DE) genes between two or more sample conditions and provides some considerations for RNA-seq experimental design. PMID- 29177665 TI - Computational Modeling of the Hsp90 Interactions with Cochaperones and Small Molecule Inhibitors. AB - Allosteric interactions of the molecular chaperone Hsp90 with a diverse array of cochaperones and client proteins, such as protein kinases and transcription factors, allow for efficient molecular communication in signal transduction networks. Deregulation of pathways involving these proteins is commonly associated with cancer pathologies and allosteric inhibition of oncogenic clients by targeting Hsp90 provides a powerful therapeutic strategy in cancer research. We review several validated computational approaches and tools used in the studies of the Hsp90 interactions with proteins and small molecules. These methods include experimentally guided docking to predict Hs90-protein interactions, molecular and binding free energy simulations to analyze Hsp90 binding with small molecules, and structure-based network modeling to evaluate allosteric interactions and communications in the Hsp90 regulatory complexes. Through the lens of allosteric-centric view on Hsp90 function and regulation, we discuss newly emerging computational tools that link protein structure modeling with biophysical simulations and network-based systems biology approaches. PMID- 29177666 TI - Computational Analysis of the Chaperone Interaction Networks. AB - We provide computational protocols to identify chaperone interacting proteins using a combination of both physical (protein-protein) and genetic (gene-gene or epistatic) interaction data derived from the published large-scale proteomic and genomic studies for the budding yeast Saccharomyces cerevisiae. Using these datasets, we discuss bioinformatic analyses that can be employed to build comprehensive high-fidelity chaperone interaction networks. Given that many proteins typically function as complexes in the cell, we highlight various step wise approaches for combining both the genetic and physical interaction datasets to decipher intra- and inter-connections for distinct chaperone- and non chaperone-containing complexes in the network. Together, these informatics procedures will aid in identifying protein complexes with distinctive functional specializations in the cell that yield a very broad and diverse set of interactions. The described procedures can also be leveraged to datasets from other eukaryotes, including humans. PMID- 29177667 TI - Immunohistochemistry of Human Hsp60 in Health and Disease: From Autoimmunity to Cancer. AB - Hsp60 (also called Cpn60) is a chaperonin with essential functions for cell physiology and survival. Additionally, its involvement in the pathogenesis of a variety of diseases (e.g., some autoimmune disorders and cancer) is becoming evident with new research. For example, the distribution and levels of Hsp60 in cells and tissues have been found altered in many pathologic conditions, and the significance of these alterations is being investigated in a number of laboratories. The aim of this ongoing research is to determine the meaning of these Hsp60 alterations with regard to pathogenetic mechanisms, diagnosis, classification of lesions, and assessing prognosis and response to treatment.Hsp60 occurs in the mitochondria, i.e., its typical residence according to classic knowledge, and also in other locales, such as the cytosol, the cell membrane, the intercellular space, and biological fluids (e.g., blood and cerebrospinal fluid). Detection and quantitative determinations in all these locations are becoming essential components of laboratory pathology in clinics and research. Consequently, immunohistochemistry targeting Hsp60 is also becoming essential for pathologists and researchers interested in disorders involving this chaperonin.In this chapter, we summarize some recent discoveries on the participation of Hsp60 in the pathogenesis of human diseases, and describe in detail how to perform immunohistochemical reactions for detecting the chaperonin, determining its location, and measuring its quantitative levels. PMID- 29177668 TI - Immunohistochemical and Flow Cytometric Analysis of Intracellular and Membrane Bound Hsp70, as a Putative Biomarker of Glioblastoma Multiforme, Using the cmHsp70.1 Monoclonal Antibody. AB - The major stress-inducible 70 kDa heat shock (stress) protein 70 (Hsp70) is frequently overexpressed in highly aggressive tumor cells and thus might serve as a tumor-specific biomarker of aggressive disease. We have previously shown that, in contrast to normal cells, tumor cells present Hsp70 on their plasma membrane. In order to elucidate the role of intracellular and membrane-bound Hsp70 as a potential tumor biomarker in glioblastoma multiforme, herein, we describe protocols for the staining of cytosolic Hsp70 in tumor formalin fixed paraffin embedded (FFPE) sections using immunohistochemistry, and for plasma membrane bound Hsp70 by multi-parametric flow cytometry using the cmHsp70.1 monoclonal antibody (mAb). PMID- 29177669 TI - Detection and Analysis of Extracellular Hsp90 (eHsp90). AB - Heat Shock Protein 90 (Hsp90) is a ubiquitous molecular chaperone that comprises about 1-3% of the total cellular protein. Over the last decade, Hsp90 has been detected and studied in the extracellular space (extracellular or eHsp90) of normal and neoplastic cells. Once outside the cell, eHsp90 has been shown to interact with extracellular client proteins and promote their stabilization and function. Cell conditioned media are routinely collected to detect and quantify eHsp90, and determine its interactions with extracellular clients. Finally, targeting specifically the eHsp90 with pharmacologic inhibitors or antibodies that are unable to cross the plasma membrane has been beneficial in inhibiting tumor cell motility and invasion. PMID- 29177670 TI - Molecular Chaperone Receptors. AB - Extracellular heat shock proteins (HSP) play important roles in cell signaling and immunity. Many of these effects are mediated by surface receptors expressed on a wide range of cell types. We have investigated the nature of such proteins by cloning candidate receptors into cells (CHO-K1) with the rare property of being null for HSP binding. Using this approach we have discovered that Hsp70 binds avidly to at least two classes of receptors including: (1) c-type lectin receptors (CLR) and (2) scavenger receptors (SR). However, the structural nature of the receptor-ligand interactions is not clear at this time. Hsp70 can bind to LOX-1 (a member of both the CLR and SR), with the c-type lectin binding domain (CTLD) as well as the SR family members SREC-I and FEEL-1/CLEVER-1/STABILIN-1, which by contrast have arrays of EGF-like repeats in their extracellular domains. In this chapter we will discuss: (1) methods for discovery of HSP receptors, (2) approaches to the study of individual receptors in cells that contain multiple such receptors, and (3) methods for investigating HSP receptor function in vivo. PMID- 29177672 TI - A Novel Heat Shock Protein 70-based Vaccine Prepared from DC-Tumor Fusion Cells. AB - We have developed an enhanced molecular chaperone-based vaccine through rapid isolation of Hsp70 peptide complexes after the fusion of tumor and dendritic cells (Hsp70.PC-F). In this approach, the tumor antigens are introduced into the antigen processing machinery of dendritic cells through the cell fusion process and thus we can obtain antigenic tumor peptides or their intermediates that have been processed by dendritic cells. Our results show that Hsp70.PC-F has increased immunogenicity compared to preparations from tumor cells alone and therefore constitutes an improved formulation of chaperone protein-based tumor vaccine. PMID- 29177671 TI - Creation of Recombinant Chaperone Vaccine Using Large Heat Shock Protein for Antigen-Targeted Cancer Immunotherapy. AB - Large heat shock proteins (HSPs) or stress proteins, including Hsp110 and Grp170, are unique molecular chaperones with superior capability of shuttling tumor protein antigens into professional antigen-presenting cells, such as dendritic cells, for highly efficient cross-presentation and T cell priming. Reconstituted chaperone complexes of large HSP and tumor protein antigen have been demonstrated to generate a robust antigen-specific T lymphocyte response with therapeutic potency against multiple cancer types in preclinical models. Here, we describe the methods for preparing this recombinant chaperone complex vaccine and analyzing the vaccine-induced activation of antigen-specific T cells using in vitro and in vivo systems. PMID- 29177673 TI - Hsp70: A Cancer Target Inside and Outside the Cell. AB - Heat shock protein 70 (Hsp70) is the most ubiquitous stress-inducible chaperone. It accumulates in the cells in response to a wide variety of physiological and environmental insults including anticancer chemotherapy, thus allowing the cell to survive to lethal conditions. Intracellular Hsp70 is viewed as a cytoprotective protein. Indeed, this protein can inhibit key effectors of the apoptotic and autophagy machineries. In cancer cells, the expression of Hsp70 is abnormally high, and Hsp70 may participate in oncogenesis and in resistance to chemotherapy. In rodent models, Hsp70 overexpression increases tumor growth and metastatic potential. Depletion or inhibition of Hsp70 frequently reduces the size of the tumors and can even cause their complete involution. However, HSP70 is also found in the extra-cellular space where it may signal via membrane receptors or endosomes to alter gene transcription and cellular function. Overall, Hsp70 extracellular function is believed to be immnunogenic and the term chaperokine to define the extracellular chaperones such as Hsp70 has been advanced. In this chapter the knowledge to date, as well as some emerging paradigms about the intra- and extra-cellular functions of Hsp70, are presented. The strategies targeting Hsp70 that are being developed in cancer therapy will also be discussed. PMID- 29177674 TI - Evidence for Hsp90 Co-chaperones in Regulating Hsp90 Function and Promoting Client Protein Folding. AB - Molecular chaperones are a diverse group of highly conserved proteins that transiently interact with partially folded polypeptide chains during normal cellular processes such as protein translation, translocation, and disassembly of protein complexes. Prior to folding or after denaturation, hydrophobic residues that are normally sequestered within a folded protein are exposed to the aqueous environment and are prone to aggregation or misfolding. Multiple classes of molecular chaperones, such as Hsp70s and Hsp40s, recognize and transiently bind polypeptides with exposed hydrophobic stretches in order to prevent misfolding. Other types of chaperones, such as Hsp90, have more specialized functions in that they appear to interact with only a subset of cellular proteins. This chapter focuses on the role of Hsp90 and partner co-chaperones in promoting the folding and activation of a diverse group of proteins with critical roles in cellular signaling and function. PMID- 29177675 TI - Clinical Evaluation and Biomarker Profiling of Hsp90 Inhibitors. AB - Inhibitors of the molecular chaperone heat shock protein 90 (Hsp90) have been in clinical development as anticancer agents since 1998. There have been 18 Hsp90 inhibitors (Hsp90i) that have entered the clinic, all of which, though structurally distinct, target the ATP-binding Bergerat fold of the chaperone N terminus. Currently, there are five Hsp90 inhibitors in clinical trial and no approved drug in this class. One impediment to development of a clinically efficacious Hsp90 inhibitor has been the very low percentage of clinical trials that have codeveloped a predictive or pharmacodynamic marker of the anticancer activity inherent in this class of drugs. Here, we provide an overview of the clinical development of Hsp90 inhibitors, review the pharmacodynamic assays that have been employed in the past, and highlight new approaches to Hsp90 inhibitor clinical development.

AB - BACKGROUND: Embryonal tumors with multilayered rosettes (ETMR) is a rare variant of embryonal tumor of infancy with nearly 200 cases reported in the literature. Leptomeningeal spread of this tumor is well known; however, extracranial metastasis has been sparsely reported in the literature. METHODS: Our study was divided into two sections: (1) We conducted a retrospective review of our patient series of ETMR and screened for patients with evidence of ETMR over the last 10 years 2007-2017 at a single tertiary referral pediatric hospital, and (2) we conducted a systematic review according to PRISMA guidelines of all reported cases of ETMR to determine the incidence of extracranial metastasis and treatment paradigms. RESULTS: Here we report three cases of extracranial non-CNS spread of ETMR and conduct a systematic review of ETMR to improve our understanding of ETMR metastases and treatment paradigms. In our systematic review (n = 204), median overall survival was less than 1 year with 44.1% children surviving over 1 year. Previously, only five cases of extracranial metastasis of ETMR have been reported. CONCLUSIONS: Our case series (n = 3) and review demonstrate that these tumors may behave like soft tissue sarcomas and may be susceptible to tumor seeding through surgical manipulation or by CSF (ventriculoperitoneal shunt). Surgery for tumor recurrence may offer an improved local disease control, but preventative measures such as meticulous surgical resection may be necessary to reduce intraoperative contamination.

AB - Synthetic polycyclic musks, widely used as additives in personal care products, are present in both biotic and abiotic matrices of the aquatic environment at concentrations of ng/l to ug/l. Although they are determined at comparatively low concentrations, these levels are biologically relevant and pose a significant growing risk as stressors to aquatic organisms. The purpose of our study was to evaluate the effects of 28-day-long exposure to polycyclic musk tonalide in zebrafish juvenile stages (Danio rerio) using selected biomarkers. Environmentally relevant concentrations of tonalide caused significant changes in selected enzyme activities in the experimental groups exposed to the highest concentrations. The activity of glutathione S-transferase and lipid peroxidation increased significantly (p < 0.05) after exposure to the highest concentration (50,000 ng/l) compared with the control. A similar trend was observed in catalase activity; there was a significant increase (p < 0.05) after exposure to two highest concentrations of tonalide (5000 and 50,000 ng/l). In addition, a statistically significant decrease (p < 0.05) in glutathione reductase activity was found in the lowest test concentration of tonalide (50 ng/l). None of the tested concentrations resulted in histopathological changes in liver, kidney, skin, or gill. Furthermore, no effects on body weight, body length, specific growth rate, and behavior were observed. Our results showed that tonalide exposure induced profound changes in the activities of antioxidant and detoxifying enzymes, such changes representing an adaptive response of the fish organism to tonalide toxicity.

AB - This study focuses on the concentrations, distribution, pollution levels, and bioavailability of 12 trace elements in soils along 6 different railways in Japan. Three diesel powered railways and three electricity powered railways were chosen as target. Surface soils (< 3 cm) were collected in vicinity of railways for analysis. Digestion and extraction were performed before concentration and bioavailability analysis. Enrichment factor was applied to investigate contamination levels of selected elements. The mean concentrations of Cr, Co, Ni, Cu, Zn, Sn, and Pb in soil samples were higher than soil background value in Japan. Concentrations of trace elements in soils along different railway had different characteristics. Horizontal distribution of Cu, Zn, Cd, Sn, and Pb in soil samples showed obviously downtrend with distance along railways with high frequency. Concentrations of V, Mn, Fe, and Co were higher in soils along railways which pass through city center. According to principal component analysis and cluster analysis, concentrations of Cu, Zn, Sn, and Pb could be considered as the indicators of soil contamination level along electricity powered trains, whereas indicators along diesel powered trains were not clear. Enrichment factor analysis proved that operation of freight trains had impact on pollution level of Cr, Ni, and Cd. Bioavailability of Mn, Co, Zn, and Cd in soil along electricity-powered railways were higher, and bioavailability of Pb in railways located in countryside was lower. Thus, enrichment and bioavailability of trace elements can be indicators of railway-originated trace elements pollution in soil.

AB - We study the adhesion limit of 3T6 fibroblasts, cultured in Dulbecco's modified Eagle's medium with 10% fetal bovine serum at 37 degrees C and 5% CO2, with a narrow-gap rotational rheometer in the parallel-disk configuration. Reducing the uncertainty in gap width to about 1 um allows studying the cells at narrow gaps, which enables to study the critical shear stress of the cells in low-viscous media. The adhesion limit on fibronectin-coated glass plates is determined as a function of concentration and adhesion time. We found that cells in groups have a tendency to detach at slightly higher shear stresses than single cells. Moreover, 60 min after the settling phase are enough for the cells to adhere to the coated plate at maximum strength. We show that the setup may also be used for cells that are not adhered from suspension, but are grown directly on the substrate.

AB - There is an urgent need for identifying nondemented individuals at the highest risk of progressing to Alzheimer's disease (AD) dementia. Here, we evaluated whether a recently validated polygenic hazard score (PHS) can be integrated with known in vivo cerebrospinal fluid (CSF) or positron emission tomography (PET) biomarkers of amyloid, and CSF tau pathology to prospectively predict cognitive and clinical decline in 347 cognitive normal (CN; baseline age range = 59.7-90.1, 98.85% white) and 599 mild cognitively impaired (MCI; baseline age range = 54.4 91.4, 98.83% white) individuals from the Alzheimer's Disease Neuroimaging Initiative 1, GO, and 2. We further investigated the association of PHS with post mortem amyloid load and neurofibrillary tangles in the Religious Orders Study and Memory and Aging Project (ROSMAP) cohort (N = 485, age at death range = 71.3 108.3). In CN and MCI individuals, we found that amyloid and total tau positivity systematically varies as a function of PHS. For individuals in greater than the 50th percentile PHS, the positive predictive value for amyloid approached 100%; for individuals in less than the 25th percentile PHS, the negative predictive value for total tau approached 85%. High PHS individuals with amyloid and tau pathology showed the steepest longitudinal cognitive and clinical decline, even among APOE epsilon4 noncarriers. Among the CN subgroup, we similarly found that PHS was strongly associated with amyloid positivity and the combination of PHS and biomarker status significantly predicted longitudinal clinical progression. In the ROSMAP cohort, higher PHS was associated with higher post-mortem amyloid load and neurofibrillary tangles, even in APOE epsilon4 noncarriers. Together, our results show that even after accounting for APOE epsilon4 effects, PHS may be useful in MCI and preclinical AD therapeutic trials to enrich for biomarker positive individuals at highest risk for short-term clinical progression.

AB - The geometrical structure, electronic and optical properties, electronic absorption spectra, vibrational frequencies, natural charge distribution, MEP analysis and thermodynamic properties of the trans and cis structures of the drug thiothixene were investigated using density functional theory (DFT) and time dependent DFT (TDDFT) methods with the B3LYP hybrid functional and 6-311 + G(d,p) basis set. The results of the calculations demonstrate that the cis structure of thiothixene has appropriate quantum properties that can act as an active medicine. The relative energies of trans and cis structures of thiothixene shows that the cis structure is more stable than the trans structure, with a small energy difference. TDDFT calculations show that the cis structure of thiothixene has the best absorption properties. The calculated NLO properties show that the NLO properties of the cis structure of thiothixene are higher than the trans structure, and the fact that the chemical hardness of the cis structure is lower than that of the trans structure that indicates that the reactivity and charge transfer of the cis isomer of thiothixene is higher than that of trans thiothixene. The molecular electrostatic potential (MEP) maps of both structures of thiothixene demonstrate that the oxygen atoms of the molecule are appropriate areas for electrophilic reactions. The vibrational frequencies of the two conformations of thiothixene demonstrate that both structures of thiothixene have almost similar modes of vibrations. The calculated thermodynamic parameters show that these quantities increase with enhancing temperature due to the enhancement of molecular vibrational intensities with temperature.

AB - Nonalcoholic fatty liver disease (NAFLD) is an important cause of chronic liver injury in many countries. The incidence of NAFLD is rising rapidly in both adults and children, because of the currently ongoing epidemics of obesity and type 2 diabetes. Notably, histological liver fibrosis is recognized as the main predictive factor for the overall long-term outcome of NAFLD, including cardiovascular disease and liver-related mortality. Thus, staging of liver fibrosis is essential in determining the prognosis and optimal treatment for patients with NAFLD and in guiding surveillance for the development of hepatocellular carcinoma (HCC). Whereas liver biopsy remains the gold standard for staging liver fibrosis, it is impossible to enforce liver biopsy in all patients with NAFLD. Noninvasive biological markers, scoring systems and noninvasive modalities are increasingly being developed and investigated to evaluate fibrosis stage of NAFLD patients. This review will highlight recent studies on the diagnosis and staging of NAFLD based on invasive (liver biopsy) or noninvasive (biomarker, scoring systems, US-based elastography and MR elastography) methods. PMID- 29177683 TI - A temporal and spatial monitoring of organotin pollution in a harborside region of Brazil by imposex and ecological quality ratio using Leucozonia nassa. AB - This study represents the first use of Leucozonia nassa (Mollusca-Gastropoda) in a program of long-term monitoring. Specimens of L. nassa were collected between 2006 and 2014 and analyzed for the occurrence of imposex in two areas in Southeastern Brazil, one control area and another characterized by the presence of many ports and marinas. Imposex was evaluated in nine sites based on the percentage of females exhibiting imposex (I%), relative penis length index and vas deferens sequence index, classical indices to evaluate tributyltin (TBT) impacts. Moreover, this study uses for the first time in a tropical environment the ecological quality ratio (EQR), an approach to verify the imposex levels as an indicator of the impact by organotin compounds according to the EU Water Framework Directive. The results confirm the occurrence of high levels of imposex in L. nassa with all the indices evaluated. Furthermore, the results also indicate that, despite the international ban, antifouling paints based on TBT are still possibly used in Brazil. In addition, this study shows that L. nassa has the characteristics that make it a suitable bioindicator to monitor TBT pollution, and that the use of the EQR may create important data regarding this problem. PMID- 29177684 TI - The effects of chilling-light stress on photosystems I and II in three Paphiopedilum species. AB - BACKGROUND: Low temperatures pose a critical limitation to the physiology and survival of chilling-sensitive plants. One example is the genus Paphiopedilum (Orchidaceae), which is mainly native to tropical and subtropical areas from Asia to the Pacific islands. However, little is known about the physiological mechanism(s) underlying its sensitivity to chilling temperature. We examined how chilling-light stress influences the activities of photosystem I (PSI) and photosystem II (PSII) in three species: P. armeniacum, P. micranthum, and P. purpuratum. All originate from different distribution zones that cover a range of temperatures. RESULTS: Photosystem II of three Paphiopedilum species was remarkable sensitivity to chilling stress. After 8 h chilling stress, the maximum quantum yield of PSII of three species of Paphiopedilum was significantly decreased, especially in P. purpuratum. The quantity of efficient PSI complex (P m ) value did not significantly differ after 8 h chilling treatment compared to the original value in three species. The stronger PSII photoinhibition and significantly less capacity for cyclic electron flow (CEF) were observed in P. purpuratum. CONCLUSIONS: In conclusion, the three species of Paphiopedilum showed significant PSII photoinhibition when exposed to 4 degrees C chilling treatment. However, their PSI activities were not susceptible to chilling-light stress during 8 h. The CEF was important for the photoprotection of PSI and PSII in P. armeniacum and P. micranthum under chilling conditions. Our findings suggested that the photosynthetic characteristics of Paphiopedilum were well adapted to their habitat. PMID- 29177685 TI - Postural stability deficit could predict ankle sprains: a systematic review. AB - PURPOSE: To perform a systematic review aimed to determine (1) if the postural stability deficit represents a risk factor for ankle sprains; (2) the most effective postural stability evaluation to predict ankle sprains and (3) eventual confounding factors that could influence postural stability and ankle sprain risk. METHODS: A systematic electronic search was performed in MEDLINE, EMBASE and CINAHL using the search terms (balance) OR (postural stability) matched with (lower limb) OR (ankle) OR (foot) and (sprain) OR (injury) on October 2 2017. All prospective studies that evaluated postural stability as risk factor for ankle sprains were included. The PRISMA Checklist guided the reporting and data abstraction. Methodological quality of all included papers was carefully assessed. RESULTS: Fifteen studies were included, evaluating 2860 individuals. Various assessment tools or instruments were used to assess postural stability. The injury incidence ranged from 10 to 34%. Postural stability deficit was recognized as risk factor for ankle sprain (OR = 1.22-10.2) in 9 cases [3 out of 3 with Star Excursion Balance Test (SEBT)]. Among the six studies that measured the center-of-gravity sway, five were able to detect worse postural stability in athletes that sustained an ankle sprain. In nine cases, the measurement of postural stability did not show any statistical relationship with ankle sprains (four out of five with examiner evaluation). In the studies that excluded patients with history of ankle sprain, postural stability was reported to be a significant risk factor in five out of six studies. CONCLUSIONS: The ultimate role of postural stability as risk factor for ankle sprains was not defined, due to the high heterogeneity of results, patient's populations, sports and methods of postural stability evaluation. Regarding assessment instruments, measurement of center-of-gravity sway could detect athletes at risk, however, standardized tools and protocols are needed to confirm this finding. The SEBT could be considered a promising tool that needs further investigation in wider samples. History of ankle sprains is an important confounding factor, since it was itself a source of postural stability impairment and a risk factor for ankle sprains. These information could guide clinicians in developing screening programs and design further prospective cohort studies comparing different evaluation tools.

PMID- 29177687 TI - Epigenetic factors Polycomb (Pc) and Suppressor of zeste (Su(z)2) negatively regulate longevity in Drosophila melanogaster. AB - The process of aging is a hallmark of the natural life span of all organisms and individuals within a population show variability in the measures of age related performance. Longevity and the rate of aging are influenced by several factors such as genetics, nutrition, stress, and environment. Many studies have focused on the genes that impact aging and there is increasing evidence that epigenetic factors regulate these genes to control life span. Polycomb (PcG) and trithorax (trxG) protein complexes maintain the expression profiles of developmentally important genes and regulate many cellular processes. Here, we report that mutations of PcG and trxG members affect the process of aging in Drosophila melanogaster, with perturbations mostly associated with retardation in aging. We find that mutations in polycomb repressive complex (PRC1) components Pc and Su(z)2 increase fly survival. Using an inducible UAS-GAL4 system, we show that this effect is tissue-specific; knockdown in fat body, but not in muscle or brain tissues, enhances life span. We hypothesize that these two proteins influence life span via pathways independent of their PRC1 functions, with distinct effects on response to oxidative stress. Our observations highlight the role of global epigenetic regulators in determining life span. PMID- 29177686 TI - Preclinical animal study of the NIPRO-ventricular assist device for use in pediatric patients. AB - Although the outcomes of patients with end-stage heart failure treated with implantable left ventricular assist devices have improved, extracorporeal left ventricular assist devices continue to play an important role, especially in pediatric patients. The present study aimed to examine the long-term biocompatibility of a small-sized extracorporeal pneumatic left ventricular assist device (NIPRO-LVAD) used in a 30- to 90-day animal experiment. The NIPRO LVAD was designed for pediatric patients or small-sized adults. The left ventricular assist device system was installed in four adult Shiba goats weighing 25.7 +/- 4.78 kg via a left thoracotomy. The outflow graft was sewn to the descending aorta and the inflow cannula was placed in the left ventricle through the left ventricular apex. Oral antiplatelet (aspirin) and oral anticoagulation therapies (warfarin) were also administered. Three out of four animals survived for a 30-day period and two goats survived for 90 days. One animal was killed early because of low pump flow due to obstruction of the inflow cannula by a left ventricular endocardial vegetation. The blood pump exhibited sufficient hydrodynamic performance with blood flows of 1.5-2.0 L/min. The animals' laboratory values were within normal limits by postoperative day 7. There was no significant thrombus formation on the housing, diaphragm, or valves of the explanted pumps. Based on the biocompatibility demonstrated in this animal study, the explanted small-sized pump may be suitable for use in left ventricular assist device systems for pediatric patients. PMID- 29177688 TI - Trifurcation of the tibial nerve within the tarsal tunnel. AB - The tibial nerve is the larger terminal branch of the sciatic nerve and it terminates in the tarsal tunnel by giving lateral and medial plantar nerves. We present a rare case of trifurcation of the tibial nerve within the tarsal tunnel. The variant nerve curves laterally after branching from the tibial nerve and courses deep to quadratus plantae muscle. Interestingly, posterior tibial artery was also terminating by giving three branches. These branches were accompanying the terminal branches of the tibial nerve. PMID- 29177689 TI - Expression of Cyclin D1 protein in residual tumor after neoadjuvant chemotherapy for breast cancer. AB - PURPOSE: Hormone receptor (HR)-positive breast cancer (BC) shows a poor response to neoadjuvant chemotherapy (NACT). New treatment targets like the Cyclin D1 CDK4/CDK6 complex are promising adjuvant/post-neoadjuvant therapeutic strategies. Evaluating Cyclin D1 overexpression in residual tumor could recognize those patients that benefit most from such post-neoadjuvant treatment. In this study, we determined Cyclin D1 expression in residual BC after NACT. Secondary aims were to correlate Cyclin D1 expression levels with clinicopathological parameters and to assess its prognostic value after NACT. METHODS: We retrospectively assessed the nuclear expression of Cyclin D1 on tissue microarrays with residual tumor from 284 patients treated in the neoadjuvant GeparTrio (n = 186) and GeparQuattro (n = 98) trials. Evaluation was performed with a standardized immunoreactive score (IRS) after selecting a cut-off value. RESULTS: A high expression level (IRS >= 6) of Cyclin D1 was found in 37.3% of the assessed specimens. An increased Cyclin D1 expression was observed in HR-positive tumors, compared to HR negative tumors (p = 0.02). Low Cyclin D1 levels correlated with clinical tumor stage 1-3 (p = 0.03). Among patients with HR-positive/Her2-negative tumors and high Cyclin D1 expression, a better disease-free survival (DFS) was graphically suggested, but not significant (p = 0.21). CONCLUSION: Our study demonstrates a measurable nuclear expression of Cyclin D1 in post-neoadjuvant residual tumor tissue of HR-positive BC. Cyclin D1 expression was not prognostic for DFS after NACT. Our results and defined cut-off suggest that the marker can be used to stratify tumors according to protein expression levels. Based on this, a prospective evaluation is currently performed in the ongoing Penelope-B trial. PMID- 29177690 TI - Obesity and Regional Immigrant Density. AB - Canada has an increasingly large immigrant population. Areas of higher immigrant density, may relate to immigrants' health through reduced acculturation to Western foods, greater access to cultural foods, and/or promotion of salubrious values/practices. It is unclear, however, whether an association exists between Canada-wide regional immigrant density and obesity among immigrants. Thus, we examined whether regional immigrant density was related to obesity, among immigrants. Adult immigrant respondents (n = 15,595) to a national population level health survey were merged with region-level immigrant density data. Multi level logistic regression was used to model the odds of obesity associated with increased immigrant density. The prevalence of obesity among the analytic sample was 16%. Increasing regional immigrant density was associated with lower odds of obesity among minority immigrants and long-term white immigrants. Immigrant density at the region-level in Canada may be an important contextual factor to consider when examining obesity among immigrants. PMID- 29177691 TI - Differential association of GABAB receptors with their effector ion channels in Purkinje cells. AB - Metabotropic GABAB receptors mediate slow inhibitory effects presynaptically and postsynaptically through the modulation of different effector signalling pathways. Here, we analysed the distribution of GABAB receptors using highly sensitive SDS-digested freeze-fracture replica labelling in mouse cerebellar Purkinje cells. Immunoreactivity for GABAB1 was observed on presynaptic and, more abundantly, on postsynaptic compartments, showing both scattered and clustered distribution patterns. Quantitative analysis of immunoparticles revealed a somato dendritic gradient, with the density of immunoparticles increasing 26-fold from somata to dendritic spines. To understand the spatial relationship of GABAB receptors with two key effector ion channels, the G protein-gated inwardly rectifying K+ (GIRK/Kir3) channel and the voltage-dependent Ca2+ channel, biochemical and immunohistochemical approaches were performed. Co immunoprecipitation analysis demonstrated that GABAB receptors co-assembled with GIRK and CaV2.1 channels in the cerebellum. Using double-labelling immunoelectron microscopic techniques, co-clustering between GABAB1 and GIRK2 was detected in dendritic spines, whereas they were mainly segregated in the dendritic shafts. In contrast, co-clustering of GABAB1 and CaV2.1 was detected in dendritic shafts but not spines. Presynaptically, although no significant co-clustering of GABAB1 and GIRK2 or CaV2.1 channels was detected, inter-cluster distance for GABAB1 and GIRK2 was significantly smaller in the active zone than in the dendritic shafts, and that for GABAB1 and CaV2.1 was significantly smaller in the active zone than in the dendritic shafts and spines. Thus, GABAB receptors are associated with GIRK and CaV2.1 channels in different subcellular compartments. These data provide a better framework for understanding the different roles played by GABAB receptors and their effector ion channels in the cerebellar network. PMID- 29177693 TI - Neuroprotective effects of nootkatone from Alpiniae oxyphyllae Fructus against amyloid-beta-induced cognitive impairment. AB - The sesquiterpene nootkatone (NKT), isolated from Alpiniae oxyphyllae Fructus, was shown to possess protective effects on neurons. In our study, by using an Alzheimer's disease (AD) model of mice induced by intracerebroventricular (i.c.v.) injection of Abeta1-42 oligomers, we investigated the effects of NKT on memory impairment and further evaluated the pathological changes of mice. AD mice were treated by i.c.v. injection of NKT (at a dose of 0.02 mg/kg and 0.20 mg/kg) or vehicle (PBS) into the lateral ventricle once daily for 5 consecutive days. The behavioral tasks were performed, and levels of some biochemical indicators and histopathological changes of the brain were evaluated to elucidate the mechanism of NKT in the treatment of AD. The results revealed that NKT significantly improved the neurobehavioral performance of the AD mice in the Y maze and Morris water maze tests. More importantly, NKT treatment decreased the malondialdehyde (MDA), Abeta as well as the acetylcholin esterase (AChE) levels in the mice brain, while increased the glutathione peroxidase (GSH-Px) levels with improved histopathological changes in the hippocampus. These findings provided evidences for the beneficial role of NKT in Abeta1-42-induced mice AD model linking to anti-oxidative and anti-AChE activities with inhibitory effect against Abeta accumulation. PMID- 29177694 TI - Phytoremediation of Cadmium by Native Plants Grown on Mining Soil. AB - The Gumuskoy mining area is located about 25 km west of Kutahya and is the largest silver deposit in Turkey. The present study investigated translocation and accumulation of cadmium (Cd) from the soil into 11 native plants. Plant and soil samples were collected from the field, and Cd concentrations were analyzed by inductively coupled plasma mass spectroscopy. Mean Cd values in the soil, root, and shoot of native plants in the study area were 82.8 +/- 5, 55.4 +/- 6, and 43.5 +/- 4 mg kg- 1, respectively. Plants were separated into several groups according to the enrichment coefficients for shoot and root values of plants. These groups showed Carduus nutans and Phlomis could be potentially bioaccumulator plants useful for phytoremediation of mining soils contaminated by Cd. PMID- 29177695 TI - Blood Lead Levels in Captive Giant Pandas. AB - Fifteen giant pandas (Ailuropoda melanoleuca) from the Chinese Conservation and Research Center for the Giant Panda (CCRCGP) in Bifengxia, Sichuan, China were analyzed for blood lead concentrations (Pb-B) during the 2017 breeding season. Thirteen of the 15 bears showed Pb-B below the method detection limit (MDL) of 3.3 ug/dL. The two remaining bears, although above the MDL, contained very low concentrations of lead of 3.9 and 4.5 ug/dL. All 15 giant pandas in this analysis had Pb-B concentrations that were within normal background concentrations for mammals in uncontaminated environments. For a threatened species, whose native country is plagued by reports of extremely high air pollution, our findings suggest that giant pandas at the CCRCGP are not absorbing lead at concentrations that would adversely affect their health. PMID- 29177692 TI - Dermatological Complications After Solid Organ Transplantation. AB - Organ transplant recipients (OTRs) are a population at high risk for cutaneous adverse events. Their early recognition and appropriate treatment is an important component of the clinical management of OTRs and should be optimally dealt with by dermatologists working in the context of a transplant dermatology clinic. Skin examination should be a standard procedure before performing organ transplantation to assess conditions which may be difficult to manage after the transplant procedure has been performed or which may represent a contraindication to transplantation, e.g., malignant melanoma. It also offers an opportunity to educate patients on skin care after organ transplantation. Skin infections can occur at any time after organ transplantation and include viral, bacterial, and fungal opportunistic infections. The risk of reactivation of latent viruses, such as varicella-zoster virus (VZV) and cytomegalovirus (CMV), is high. Bacterial infections are frequent and may be caused by unusual agents such Actinomyces, Mycobacteria, Legionella, or Nocardia. A large spectrum of fungal infections may occur, ranging from superficial (e.g., dermatophytes) to deeper and more severe ones (Alternaria, Aspergillus, Cryptococcus, Histoplasma). Drug-related idiosyncratic reactions usually occur early after the introduction of the causative drug, e.g., hypersensitivity reaction to azathioprine. On the long-term run, cutaneous effects due to cumulative drug toxicity, e.g., sebaceous hyperplasia from cyclosporine, may appear. Rare immunologically driven inflammatory reactions may occur in OTRs such as GVH or autoimmune disease. Tumors are particularly frequent. Kaposi's sarcoma, associated with persistent human herpes virus 8 (HHV8) infection, and cutaneous anaplastic large-cell lymphoma (ALCL) occur early after transplantation. Other cancers, such as nonmelanoma skin cancer (NMSCs), associated with persistent human papillomavirus (HPV) infections, malignant melanoma, Merkel cell carcinoma, or adnexal tumors, manifest later with an incidence which is much higher than observed in the general population. The incidence increases further after a first NMSC occurs. PMID- 29177696 TI - Leaching Characteristics of Calcium and Strontium from Phosphogypsum Under Acid Rain. AB - Phosphogypsum (PG) stored close to phosphorus chemical plants has caused worldwide environmental problems. Column leaching experiments were conducted to evaluate Ca and Sr leaching from PG under simulated acid rain at pH levels typical for rain in the study region (Shifang, China). High concentrations of Ca and Sr in leachates in the first five leaching events could pollute the soil and groundwater around the PG. Leachates pH was lower than and had no correlation with simulated rain pH. No correlations between simulated rain pH and cumulative Ca and Sr content in leachates were noted. Around 2.0%-2.2% of Ca and 0.5%-0.6% of Sr were leached out from PG by the simulated summer rainfall in Shifang. Electrical conductivity values, Ca and Sr concentrations at bottom sections of PG columns were higher than those of top sections, while pH values showed a reverse trend. More precautions should be taken to protect the environment around PG stacks. PMID- 29177697 TI - Neuroprotective and Anti-inflammatory Effects of a Dodecamer Peptide Harboring Ninjurin 1 Cell Adhesion Motif in the Postischemic Brain. AB - It has been reported that the innate immune response plays important roles in brain ischemia and that the infiltration of blood-derived immune cells is a key initiator of this response. Nerve injury-induced protein 1 (Ninjurin 1, Ninj1) is a cell adhesion molecule responsible for cell-to-cell interactions between immune cells and endothelial cells. In the present study, we investigated the proinflammatory and neuroprotective effects of Ninj1 and a dodecamer peptide harboring Ninj1 N-terminal adhesion motif (N-NAM, Pro26~Asn37) in a rat middle cerebral artery occlusion (MCAO) model of stroke. Ninj1 was predominantly induced in neutrophils and endothelial cells in the ischemic hemispheres around 12 h to 1 day post-MCAO, which coincided with a massive neutrophil influx. We demonstrated that intranasal administration of Ninj1 small interfering RNA (siRNA) or N-NAM significantly blocked neutrophil infiltration in postischemic brains. In addition, intranasal administration of Ninj1 siRNA or N-NAM reduced the mean infarct volume to 46.5 +/- 9.2 or 30.6 +/- 11.7% of that of the PBS-treated MCAO controls, respectively, which was accompanied by significant amelioration of neurological and motor deficits. We showed that N-NAM or Ninj1 siRNA effectively blocked the adhesion and transendothelial migration of TNF-alpha-stimulated human myelocytic leukemia cells to human umbilical vein endothelial cells and similarly suppressed adhesion and migration of monocytes. Activations of phosphoinositide 3 kinase and Ras-related C3 botulinum toxin substrate 1 are involved in these Ninj1 mediated processes and can be inhibited by N-NAM or Ninj1 siRNA. These results indicate that Ninj1 plays an important role in neutrophil infiltration in the postischemic brain and N-NAM confers robust neuroprotective and anti-inflammatory effects by inhibiting Ninj1-mediated infiltration of neutrophils. PMID- 29177698 TI - Evolution of early phase clinical trials in oncology. AB - The therapeutic armamentarium for the treatment of cancer has rapidly evolved with the advent of molecularly targeted and immuno-oncology agents. Dramatic and prolonged responses observed in patients with advanced cancers have created excitement and promise for expedited development of effective new treatments. However, this has also necessitated a rethinking of our early phase clinical trial designs and the process of optimally developing a novel agent. In this review, we discuss the current state and future directions of phase I clinical trials in oncology. Firstly, we cover the statistical methodologies behind rules and model-based dose escalation designs, and what the future holds for optimal dose selection beyond targeting the maximum tolerated dose. Next, we discuss the recent adoption of seamless expansion strategies to expedite drug development timelines, highlighted by the pembrolizumab KEYNOTE-001 trial, and potential pitfalls with this approach. Finally, we delve into the concepts behind genomic matching trials, including early success stories and the challenges that lie ahead. PMID- 29177699 TI - A Phase IC Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Cognitive Outcomes of BI 409306 in Patients with Mild-to-Moderate Schizophrenia. AB - INTRODUCTION: This randomized, double-blind, parallel-group study investigated the safety, tolerability, pharmacokinetics (PK), and cognitive outcomes of BI 409306-a selective phosphodiesterase 9A (PDE9A) inhibitor-in patients with schizophrenia. METHODS: Patients with mild-to-moderate schizophrenia were randomized (1:1:1:1) to receive BI 409306 at 25, 50, or 100 mg or placebo once daily over 14 days. The primary endpoints were safety and tolerability; the secondary endpoints were PK and cognitive outcomes. RESULTS: Of the 40 randomized patients, 38 (95%) completed the study. Patients were predominantly male (87.5%; mean age, 40.2 years). After a single dose, C max was reached within 30-45 min. The geometric mean (gMean) C max and AUC0-infinity ranged from 138 to 998 nmol/L and 217 to 2020 nmol?h/L, respectively. Elimination was rapid (gMean t 1/2 range 1.10-1.85 h). After multiple doses, C max,ss was reached within 1 h; elimination was similar to that observed after a single dose. Total exposure at steady state and after a single dose were similar (accumulation ratio range: AUC, 0.758-1.13 and Cmax, 0.768-1.40). No deaths, adverse events (AEs) leading to discontinuation, or serious AEs were observed. Treatment-emergent AEs were mild, with no apparent dose-related trends. There was no worsening of schizophrenia symptoms (Positive and Negative Syndrome Scale) and no trends in suicidality (Columbia Suicide Severity Rating Scale). The Hopkins Verbal Learning Test Revised (HVLT-R) and Brief Visuospatial Memory Test-Revised (BVMT-R) showed no effect on cognitive function. CONCLUSION: Administration of BI 409306 in patients with mild-to-moderate schizophrenia resulted in satisfactory safety and tolerability. BI 409306, PK was characterized by rapid absorption, monophasic to biphasic elimination, and minor accumulation with multiple dosing. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT01892384. FUNDING: Boehringer Ingelheim Pharma GmbH & Co. KG. PMID- 29177700 TI - Novel Mutations in PLOD2 Cause Rare Bruck Syndrome. AB - Bruck syndrome is a rare autosomal recessive form of osteogenesis imperfecta (OI), which is mainly characterized by joint contractures and recurrent fragility fractures. Mutations in FKBP10 and PLOD2 were identified as the underlying genetic defects of Bruck syndrome. Here we investigated the phenotypes and the pathogenic mutations of three unrelated Chinese patients with Bruck syndrome. Clinical fractures, bone mineral density (BMD), bone turnover biomarkers, and skeletal images were evaluated in detail. The pathogenic mutations were identified by targeted next-generation sequencing and subsequently confirmed by Sanger sequencing and cosegregation analysis. We also evaluated the effects of zoledronic acid on bone fracture incidence and BMD of the patients. Three patients had congenital joint contractures, recurrent fragility fractures, camptodactyly, clubfoot, scoliosis, but without dentinogenesis imperfecta and hearing loss. Five novel heterozygous mutations were detected in PLOD2, including three heterozygous missense mutations (c.1138C>T, p.Arg380Cys; c.1153T>C, p.Cys385Arg; and c.1982G>A, p.Gly661Asp), one heterozygous nonsense mutation (c.2038C>T, p.Arg680X), and one heterozygous splice-site mutation (c.503-2A>G). Their parents were all heterozygous carriers of these mutations in PLOD2. No clear genotype-phenotype correlations were found in these patients with PLOD2 mutations. Z-score of BMD was significantly increased, but scoliosis progressed and new bone fractures occurred during the treatment of zoledronic acid. Our findings expanded the spectrum of gene mutations of Bruck syndrome. PMID- 29177702 TI - [Bruch's membrane opening minimum rim width : Correlation and diagnostic accuracy in comparison to peripapillary retinal nerve fiber layer thickness]. AB - BACKGROUND: Glaucoma is one of the main causes of blindness in the Western hemisphere. Because the disease often painlessly progresses it remains unnoticed until major optic nerve head damage occurs in many cases. That is why new, more sensitive diagnostic methods are needed. Bruch's membrane opening minimum rim width (BMO-MRW), measured with the new glaucoma module premium edition (GMPE) was recently introduced as a more accurate tool to detect glaucomatous changes. The purpose of this study was to assess the correlation of SPECTRALIS(r) spectral domain optical coherence tomography (SD-OCT) and the GMPE anatomic positioning module (APS module) for retinal nerve fiber layer thickness (RNFLT) measurements. The second aim was to assess the diagnostic accuracy of BMO-MRW. METHODS: Prospective study of 41 eyes (41 patients) with glaucoma and 26 eyes from 26 healthy controls. Scans were obtained using SPECTRALIS(r) SD-OCT and RNFLT was measured with both modules and compared using Spearman's rank test. The BMO-MRW was assessed by GMPE. Sensitivity, specificity and area under receiver operating characteristics curves (AUROC) of each sector of the optic nerve were calculated and compared using the method of Delong et al. RESULTS: We found a positive correlation (0.694-0.955, p < 0.0001) between RNFLT measurements by standard SD OCT and all diameters of RNFLT of APS module within all sectors. The AUROC of RNFLT in standard SD-OCT was 0.693 for the inferior nasal sector (NI) and BMO-MRW was 0.85 in NI. The difference in AUROC was statistically significant (p = 0.0049). No other sector showed statistically significant differences. CONCLUSION: The RNFLT measurements of both modules showed a positive correlation and appear to be comparable. The BMO-MRW in one sector (NI) showed a significantly higher accuracy of measurement than standard RNFLT. All other sectors showed a comparable accuracy of measurement. PMID- 29177701 TI - Ultrasound classification of traumatic distal biceps brachii tendon injuries. AB - OBJECTIVE: The present work is aimed at analysing ultrasound findings in patients with distal biceps brachii tendon (DBBT) injuries to assess the sensitivity of ultrasound in detecting the different forms of injury, and to compare ultrasound results with magnetic resonance imaging (MRI) and surgical results. MATERIALS AND METHODS: A total of 120 patients with traumatic DBBT injuries examined between 2011 and 2015 were analysed. We compared ultrasound results with MRI results when surgery was not indicated and with MRI and surgical results when surgery was indicated. RESULTS: For major DBBT injuries (complete tears and high-grade partial tears), the concordance study between exploration methods and surgical results found that ultrasound presented a slight statistically significant advantage over MRI (ultrasound: kappa = 0.95-very good-95% CI 0.88 to 1.01, MRI: kappa = 0.63-good-95% CI 0.42 to 0.84, kappa difference p < 0.01). Minor injuries, in which most tendon fibres remain intact (tendinopathies, elongations and low-grade partial tears), are the most difficult to interpret, as ultrasound and MRI reports disagreed in 12 out of 39 cases and no surgical confirmation could be obtained. CONCLUSIONS: Based on present results and previous MRI classifications, we establish a traumatic DBBT injury ultrasound classification. The sensitivity and ultrasound-surgery correlation results in the diagnosis of major DBBT injuries obtained in the present study support the recommendation that ultrasound can be used as a first-line imaging modality to evaluate DBBT injuries. PMID- 29177703 TI - Evaluation of four commercial quantitative real-time PCR kits with inhibited and degraded samples. AB - DNA quantification is a vital step in forensic DNA analysis to determine the optimal input amount for DNA typing. A quantitative real-time polymerase chain reaction (qPCR) assay that can predict DNA degradation or inhibitors present in the sample prior to DNA amplification could aid forensic laboratories in creating a more streamlined and efficient workflow. This study compares the results from four commercial qPCR kits: (1) Investigator(r) Quantiplex(r) Pro Kit, (2) Quantifiler(r) Trio DNA Quantification Kit, (3) PowerQuant(r) System, and (4) InnoQuant(r) HY with high molecular weight DNA, low template samples, degraded samples, and DNA spiked with various inhibitors.The results of this study indicate that all kits were comparable in accurately predicting quantities of high quality DNA down to the sub-picogram level. However, the InnoQuant(R) HY kit showed the highest precision across the DNA concentration range tested in this study. In addition, all kits performed similarly with low concentrations of forensically relevant PCR inhibitors. However, in general, the Investigator(r) Quantiplex(r) Pro Kit was the most tolerant kit to inhibitors and provided the most accurate quantification results with higher concentrations of inhibitors (except with salt). PowerQuant(r) and InnoQuant(r) HY were the most sensitive to inhibitors, but they did indicate significant levels of PCR inhibition. When quantifying degraded samples, each kit provided different degradation indices (DI), with Investigator(r) Quantiplex(r) Pro indicating the largest DI and Quantifiler(r) Trio indicating the smallest DI. When the qPCR kits were paired with their respective STR kit to genotype highly degraded samples, the Investigator(r) 24plex QS and GlobalFiler(r) kits generated more complete profiles when the small target concentrations were used for calculating input amount. PMID- 29177704 TI - Inconsistent genotyping call at DYS389 locus and implications for interpretation. AB - The male-specific Y chromosome short tandem repeat (STR) locus is used widely in forensic case, which are useful molecular tool to providing the biological evidence for male/female mixture and paternal lineage cases. The Y-STR analysis has been greatly facilitated by advent of commercial multiplex kit. However, even with well-designed robust multiplex kit, abnormal genotyping profile may be observed when encountering with mutations, such as deletion/duplication within the target region or mutation at the primer binding site. In this study, a single allele shift by five nucleotides for the DYS389I marker between the AmpFlSTR(r) Yfiler(r) and Yfiler(r) Plus PCR amplification kits while the same allele count for DYS389II was observed in eight unrelated Chinese male individuals. After further investigations by re-amplified with three additional multiplex kits, sanger, and next-generation sequencing, the discordance was finally proven caused by existing rare mutation in those sample, which contained two adjacent SNPs only one base apart in the sequence. This paper describes the molecular basis of the discordance at DYS389I genotyping between different commercial multiplex kits and could provide available information for enhancing of interpretation of abnormal Y STR genotyping in forensic practice. PMID- 29177705 TI - Acid-facilitated product release from a Mo(IV) center: relevance to oxygen atom transfer reactivity of molybdenum oxotransferases. AB - We report that pyridinium ions (HPyr+) accelerate the conversion of [Tp*MoIVOCl(OPMe3)] (1) to [Tp*MoIVOCl(NCCH3)] (2) by 103-fold, affording 2 in near-quantitative yield; Tp* = hydrotris(3,5-dimethyl-1-pyrazolyl)borate. This novel reactivity and the mechanism of this reaction were investigated in detail. The formation of 2 followed pseudo-first-order kinetics, with the observed pseudo first-order rate constant (k obs) linearly correlated with [HPyr+]. An Eyring plot revealed that this HPyr+-facilitated reaction has a small positive value of ?S ? indicative of a dissociative interchange (Id) mechanism, different from the slower associative interchange (Ia) mechanism in the absence of HPyr+ marked with a negative ?S ?. Interestingly, log(k obs) was found to be linearly correlated to the acidity of substituted pyridinium ions. This novel reactivity is further investigated using combined DFT and ab initio coupled cluster methods. Different reaction pathways, including Id, Ia, and possible alternative routes in the absence or presence of HPyr+, were considered, and enthalpy and free energies were calculated for each pathway. Our computational results further underscored that the Id route is energetically favored in the presence of HPyr+, in contrast with the preferred Ia-NNO pathway in the absence of HPyr+. Our computational results also revealed molecular-level details for the HPyr+-facilitated Id route. Specifically, HPyr+ initially becomes hydrogen-bonded to the oxygen atom of the Mo(IV)-OPMe3 moiety, which lowers the activation barrier for the Mo-OPMe3 bond cleavage in a rate-limiting step to dissociate the OPMe3 product. The implications of our results were discussed in the context of molybdoenzymes, particularly the reductive half-reaction of sulfite oxidase. PMID- 29177706 TI - Prognostic value of vasodilator response using rubidium-82 positron emission tomography myocardial perfusion imaging in patients with coronary artery disease. AB - BACKGROUND: Prognostic value of positron emission tomography (PET) myocardial perfusion imaging (MPI) is well established. There is paucity of data on how the prognostic value of PET relates to the hemodynamic response to vasodilator stress. We hypothesize that inadequate hemodynamic response will affect the prognostic value of PET MPI. METHODS AND RESULTS: Using a multicenter rubidium (Rb)-82 PET registry, 3406 patients who underwent a clinically indicated rest/stress PET MPI with a vasodilator agent were analyzed. Patients were categorized as, "responders" [increase in heart rate >= 10 beats per minute (bpm) and decrease in systolic blood pressure (SBP) >=10 mmHg], "partial responders" (either a change in HR or SBP), and "non-responders" (no change in HR or SBP). Primary outcome was all-cause death (ACD), and secondary outcome was cardiac death (CD). Ischemic burden was measured using summed stress score (SSS) and % left ventricular (LV) ischemia. After a median follow-up of 1.68 years (interquartile range = 1.17- 2.55), there were 7.9% (n = 270) ACD and 2.6% (n = 54) CD. Responders with a normal PET MPI had an annualized event rate (AER) of 1.22% (SSS of 0-3) and 1.58% (% LV ischemia = 0). Partial and non-responders had higher AER with worsening levels of ischemic burden. In the presence of severe SSS >=12 and LV ischemia of >=10%, partial responders had an AER of 10.79% and 10.36%, compared to non-responders with an AER of 19.4% and 12.43%, respectively. Patient classification was improved when SSS was added to a model containing clinical variables (NRI: 42%, p < 0.001) and responder category was added (NRI: 61%, p < 0.001). The model including clinical variables, SSS and hemodynamic response has good discrimination ability (Harrell C statistics: 0.77 [0.74 0.80]). CONCLUSION: Hemodynamic response during a vasodilator Rb-82 PET MPI is predictive of ACD. Partial and non-responders may require additional risk stratification leading to altered patient management. PMID- 29177707 TI - A first-in-man PET study of [18F]PSS232, a fluorinated ABP688 derivative for imaging metabotropic glutamate receptor subtype 5. AB - PURPOSE: Non-invasive imaging of metabotropic glutamate receptor 5 (mGlu5) in the brain using PET is of interest in e.g., anxiety, depression, and Parkinson's disease. Widespread application of the most widely used mGlu5 tracer, [11C]ABP688, is limited by the short physical half-life of carbon-11. [18F]PSS232 is a fluorinated analog with promising preclinical properties and high selectivity and specificity for mGlu5. In this first-in-man study, we evaluated the brain uptake pattern and kinetics of [18F]PSS232 in healthy volunteers. METHODS: [18F]PSS232 PET was performed with ten healthy male volunteers aged 20 40 years. Seven of the subjects received a bolus injection and the remainder a bolus/infusion protocol. Cerebral blood flow was determined in seven subjects using [15O]water PET. Arterial blood activity was measured using an online blood counter. Tracer kinetics were evaluated by compartment modeling and parametric maps were generated for both tracers. RESULTS: At 90 min post-injection, 59.2 +/- 11.1% of total radioactivity in plasma corresponded to intact tracer. The regional first pass extraction fraction of [18F]PSS232 ranged from 0.41 +/- 0.06 to 0.55 +/- 0.03 and brain distribution pattern matched that of [11C]ABP688. Uptake kinetics followed a simple two-tissue compartment model. The volume of distribution of total tracer (V T, ml/cm3) ranged from 1.18 +/- 0.20 for white matter to 2.91 +/- 0.51 for putamen. The respective mean distribution volume ratios (DVR) with cerebellum as the reference tissue were 0.88 +/- 0.06 and 2.12 +/- 0.10, respectively. The tissue/cerebellum ratios of a bolus/infusion protocol (30/70 dose ratio) were close to the DVR values. CONCLUSIONS: Brain uptake of [18F]PSS232 matched the distribution of mGlu5 and followed a two-tissue compartment model. The well-defined kinetics and the possibility to use reference tissue models, obviating the need for arterial blood sampling, make [18F]PSS232 a promising fluorine-18 labeled radioligand for measuring mGlu5 density in humans.

AB - Solar cells based on subwavelength-dimensions semiconductor nanowire (NW) arrays promise a comparable or better performance than their planar counterparts by taking the advantages of strong light coupling and light trapping. In this paper, we present an accurate and time-saving analytical design for optimal geometrical parameters of vertically aligned InP NWs for maximal solar energy absorption. Short-circuit current densities are calculated for each NW array with different geometrical dimensions under solar illumination. Optimal geometrical dimensions are quantitatively presented for single, double, and multiple diameters of the NW arrays arranged both squarely and hexagonal achieving the maximal short-circuit current density of 33.13 mA/cm2. At the same time, intensive finite-difference time-domain numerical simulations are performed to investigate the same NW arrays for the highest light absorption. Compared with time-consuming simulations and experimental results, the predicted maximal short-circuit current densities have tolerances of below 2.2% for all cases. These results unambiguously demonstrate that this analytical method provides a fast and accurate route to guide high performance InP NW-based solar cell design.

AB - PURPOSE OF REVIEW: The purpose of the present review was threefold: to address the current state of Animal-Assisted Interactions (AAI) within the military; to summarize recent literature (within the past three years) in the field of AAI; and to discuss trends in AAI research since 2014. RECENT FINDINGS: With regard to AAI within the military, several canine interaction programs have been utilized to assist service members in coping with various issues. Therapy dogs have been deployed with Combat-Operational Stress Control units; they have been integrated into medical clinics and behavioral health treatment programs in garrison; and policy has been developed to address the use of therapy animals in military treatment facilities. General research in AAI has demonstrated efficacy for certain presenting issues (stress management, trauma, autism spectrum disorder) and specific populations (children, the elderly, acute care patients). Overall trends in research include calls for increased consideration for animal welfare in AAI and increased rigor in research methodology. Current research supports the structured use of therapy dogs in the treatment of various disorders and with specific populations, including military service members and veterans; however, the need for additional research with rigorous methodology remains. PMID- 29177711 TI - What makes the difference in people's lives when they have a mental disorder? AB - OBJECTIVES: The objective of this study was to identify which environmental factors are the most responsible for the disability experienced by persons with mental disorders and whether they differ (1) from those in cardiovascular diseases, chronic respiratory conditions, diabetes, and cancer, and (2) depending on the capacity level-a proxy for the impact of health conditions on the health state of individuals. METHODS: Nationally representative data from 12,265 adults in Chile collected in 2015 with the WHO Model Disability Survey was analyzed. RESULTS: The availability of personal assistance, frequency of receiving personal assistance, and assistive devices for mobility were the most important environmental factors across mental and other non-communicable diseases. Perception of discrimination and use of health services were also prominent factors. There was a huge overlap between the factors found relevant for mental and other non-communicable diseases, but a substantial variability depending on the intensity of difficulties in capacity. CONCLUSIONS: This study challenges the appropriateness of disease-specific approaches and suggests that considering intrinsic capacity levels is more informative than focusing on diagnosis alone when comparing needs and barriers that affect the performance in daily life of specific groups of individuals. PMID- 29177713 TI - A Model of Isotope Separation in Plants. AB - A model representing isotope separation during water evaporation in plants was constructed. The model accounts for substance diffusion, convective transfer and evaporation from the surface of the leaves. The dependence of the system's separation and enrichment coefficients on various parameters (liquid velocity, diffusion coefficient, and potential barriers for molecules and their thermal velocities) was determined. A comparison was made between the enrichment coefficients calculated from experimental data from different plants and those based on the model. Qualitative agreement between the experimental and theoretical values was obtained for the case of [Formula: see text], where u is the average velocity of water in the plant, h is the height of the plant, and D is the diffusion coefficient of the substance. PMID- 29177712 TI - Laser photocoagulation as treatment of non-exudative age-related macular degeneration: state-of-the-art and future perspectives. AB - PURPOSE: To give an updated review of laser approaches to non-exudative age related macular degeneration (AMD). METHODS: PubMed and Medline database searches were carried out using the terms "laser" and "photocoagulation" associated with "age-related macular degeneration", and latest publications up to May 2017 have been reviewed. Moreover, the design of an ongoing single-center, non-randomized, phase I-II, pilot study, the PASCAL-GA trial, coordinated by F. Bandello, MD and G. Querques, MD from the IRCCS Ospedale San Raffaele, is described. RESULTS: Either standard or subthreshold laser strategies have been tried to induce regression of distinct phenotypes of AMD, as reticular pseudodrusen (RPD), nascent geographic atrophy (nGA), and drusen-associated geographic atrophy (DAGA), with heterogeneous results. The aim of the PASCAL-GA protocol is to assess if subthreshold laser can restore the retinal pigment epithelium function in eyes with RPD and nGA offering a protective effect against extensive GA. CONCLUSIONS: New-generation medical and surgical approaches, including subthreshold laser photocoagulation, may have some success in downstaging AMD. PMID- 29177714 TI - Non-invasive high-intensity focused ultrasound for UV-induced hyperpigmentation in Fitzpatrick skin types III and IV: a prospective, randomized, controlled, evaluator-blinded trial. AB - Skin hyperpigmentation is a frequently encountered problem, particularly in darker skin types. Unfortunately, standard treatments for this condition have shown disappointing results. High-intensity focused ultrasound (HIFU) is commonly indicated for skin laxity, but recently was used to treat UV-induced hyperpigmentation in animal models. This study is aimed to evaluate the efficacy and safety of high-intensity focused ultrasound for UVB-induced hyperpigmentation in human subjects. A randomized, evaluator-blinded pilot study was conducted on 20 subjects. Each subject was induced three hyperpigmentary spots by local broadband UVB. After 2 weeks, each spot was randomly allocated to control, low energy, and high-energy HIFU. Subjects were instructed to follow up weekly for a duration of 1 month. Lightness index measurements, mean improvement scores, subjects' satisfaction, pain scores, and side effects were evaluated. All 20 subjects completed the study. Fourteen subjects had Fitzpatrick (FPT) skin type III and six subjects had FPT skin type IV. Twelve subjects showed greater improvement at control sites while eight subjects showed greater improvement at HIFU-treated sites. In FPT skin type III, HIFU appeared to be inferior to control in both lightness index and mean improvement scores, but in FPT skin type IV, HIFU had greater lightness index improvement and higher improvement scores than control. Side effects were more frequent in high-energy-treated areas. Focused ultrasound may be offered in some patients with hyperpigmentary conditions. More research is needed to determine proper energy settings for optimal outcome. PMID- 29177715 TI - Is bone morphogenic protein-2 useful in revision total hip arthroplasty with acetabular defects? PMID- 29177716 TI - Pcal_0632, a phosphorylating glyceraldehyde-3-phosphate dehydrogenase from Pyrobaculum calidifontis. AB - Genome sequence of the hyperthermophilic archaeon Pyrobaculum calidifontis contains an open reading frame, Pcal_0632, annotated as glyceraldehyde-3 phosphate dehydrogenase, which is partially overlapped with phosphoglycerate kinase. In the phylogenetic tree, Pcal_0632 clustered with phosphorylating glyceraldehyde-3-phosphate dehydrogenases characterized from hyperthermophilic archaea and exhibited highest identity of 54% with glyceraldehyde-3-phosphate dehydrogenase from Sulfolobus tokodaii. To examine biochemical function of the protein, Pcal_0632 gene was expressed in Escherichia coli and the gene product was purified. The recombinant enzyme catalyzed the conversion of glyceraldehyde 3 phosphate and inorganic phosphate into 1,3-bisphosphoglycerate utilizing both NAD and NADP as cofactor with a marked preference for NADP. The enzyme was highly stable against temperature and denaturants. Half-life of the enzyme was 60 min at 100 degrees C. It retained more than 60% of its activity even after an incubation of 72 h at room temperature in the presence of 6 M urea. High thermostability and resistance against denaturants make Pcal_0632 a novel glyceraldehyde-3-phosphate dehydrogenase. PMID- 29177717 TI - Biochemical characterization of a thermostable endomannanase/endoglucanase from Dictyoglomus turgidum. AB - Dictyoglomus turgidum is a hyperthermophilic, anaerobic, gram-negative bacterium that shows an array of putative glycoside hydrolases (GHs) encoded by its genome, a feature that makes this microorganism very interesting for biotechnological applications. The aim of this work is the characterization of a hyperthermophilic GH5, Dtur_0671, of D. turgidum, annotated as endoglucanase and herein named DturCelB in agreement to DturCelA, which was previously characterized. The synthetic gene was expressed in Escherichia coli. The purified recombinant enzyme is active as a monomer (40 kDa) and CD structural studies showed a conserved alpha/beta structure at different temperatures (25 and 70 degrees C) and high thermoresistance (Tm of 88 degrees C). Interestingly, the enzyme showed high endo-beta-1,4-mannanase activity vs various mannans, but low endo-beta-1,4 glucanase activity towards carboxymethylcellulose. The K M and V max of DturCelB were determined for both glucomannan and CMC: they were 4.70 mg/ml and 473.1 MUmol/min mg and 1.83 mg/ml and 1.349 MUmol/min mg, respectively. Its optimal activity towards temperature and pH resulted to be 70 degrees C and pH 5.4, respectively. Further characterization highlighted good thermal stability (~ 50% of enzymatic activity after 2 h at 70 degrees C) and pH stability over a broad range (> 90% of activity after 1 h in buffer, ranging pH 5-9); resistance to chemicals was also observed.

AB - The theory of glucose-responsive composite membranes for the planar diffusion and reaction process is extended to a microsphere membrane. The theoretical model of glucose oxidation and hydrogen peroxide production in the chitosan-aliginate microsphere has been discussed in this manuscript for the first time. We have successfully reported an analytical derived methodology utilizing homotopy perturbation to perform the numerical simulation. The influence and sensitive analysis of various parameters on the concentrations of gluconic acid and hydrogen peroxide are also discussed. The theoretical results enable to predict and optimize the performance of enzyme kinetics. PMID- 29177719 TI - Structural features influential to enzymatic hydrolysis of cellulose-solvent based pretreated pinewood and elmwood for ethanol production. AB - Dissolution of lignocelluloses in N-methylmorpholine-N-oxide (NMMO or NMO) at moderate conditions, e.g., 120 degrees C for 3 h under atmospheric pressure, and regeneration with water, is among the most effective nonderivatization pretreatment for the improvement of enzymatic hydrolysis and ethanol production. The effects of the pretreatment on two different types of wood, hardwood elm and softwood pine, were compared via physicochemical structural analyses, i.e., FTIR, XRD, SEM, TGA, and enzyme adsorption techniques, to relate their properties to the extent of enzymatic conversion. After the pretreatment, cellulose was highly recovered and characterized to be mainly cellulose II and amorphous cellulose, with lower cellulose crystallinity index, higher thermal stability, and more favorable surface features for hydrolysis, compared to native woods. Moreover, the strength of enzyme binding onto the lignocelluloses, which was directly related to the enzymatic hydrolysis rate, increased by 57% and 164% for pinewood and elmwood, respectively. The highest total reducing sugars yield for untreated pinewood was 9.8% (74 mg/g-substrate) and improved to 58.5% (330 mg/g-substrate) after the pretreatment, whereas the corresponding values for elmwood were 14.7% (104 mg/g-substrate) vs. 51.4% (274 mg/g-substrate). Furthermore, maximum ethanol theoretical yields of 63.5 and 41.4% were obtained from pinewood and elmwood by Saccharomyces cerevisiae and Mucor indicus, respectively. PMID- 29177720 TI - Recombinant biosynthesis of bacterial cellulose in genetically modified Escherichia coli. AB - Bacterial cellulose (BC) exhibits unique properties such as high purity compared to plant-based cellulose; however, commercial production of BC has remained a challenge, primarily due to the strain properties of cellulose-producing bacteria. Herein, we developed a functional and stable BC production system in genetically modified (GM) Escherichia coli by recombinant expression of both the BC synthase operon (bcsABCD) and the upstream operon (cmcax, ccp Ax). BC production was achieved in GM HMS174 (DE3) and in GM C41 (DE3) by optimization of the culture temperature (22 degrees C, 30 degrees C, and 37 degrees C) and IPTG concentration. BC biosynthesis was detected much earlier in GM C41 (DE3) cultures (3 h after IPTG induction) than those of Gluconacetobacter hansenii. GM HMS174 (DE3) produced dense fibres having a length of approximately 1000-3000 MUm and a diameter of 10-20 MUm, which were remarkably larger than the fibres of BC typically produced by G. hansenii. PMID- 29177721 TI - Is the Positive Bias an ADHD Phenomenon? Reexamining the Positive Bias and its Correlates in a Heterogeneous Sample of Children. AB - The goals of this study were to (a) evaluate the presence of the positive bias (PB) in elementary-school-aged children with and without ADHD when PB is defined at the individual level through latent profile analysis and (b) examine the extent to which several correlates (i.e., social functioning, aggression, depression, and anxiety) are associated with the PB. Participants were 233 youth (30% female; 8 to 10 years of age), 51% of whom met criteria for ADHD. During an individual evaluation, children and parents completed a battery of questionnaires to assess child competence, depression, anxiety, and aggression. Children also participated in a novel group session with same-sex unfamiliar peers (half of the group was comprised of children with ADHD) to engage in group problem-solving tasks and free play activities. After the group session, peers and staff completed ratings of each child's behavior (e.g., likeability, rule following). The best fitting LPA model for parent and self-ratings of competence revealed four profiles: High Competence/Self-Aware; Variable Competence/Self-Aware; Low Competence/Self-Aware; and Low Competence/PB, in which the PB was present across domains. Only 10% of youth showed a PB and youth with ADHD were no more likely to display the PB than their non-ADHD peers with similar levels of low competence. Lastly, the Low Competence/Self-Aware profile demonstrated higher levels of anxiety and depression than the Low Competence/PB profile; the profiles did not differ on aggression or peer or staff ratings of social/behavioral functioning. Implications for understanding the PB in children with and without ADHD are discussed. PMID- 29177722 TI - A cross-sectional study on the mechanical properties of the Achilles tendon with growth. AB - PURPOSE: This study aimed to elucidate growth pattern of mechanical properties of the Achilles tendon and to examine if imbalance between growth of bone and muscle tendon unit occurs during adolescence. METHODS: Fourteen elementary school boys, 30 junior high school boys, 20 high school boys and 15 male adults participated in this study. Based on estimated age at peak height velocity (PHV), junior high school boys were separated into two groups (before or after PHV). An ultrasonography technique was used to determine the length, cross-sectional area, stiffness and Young's modulus of Achilles tendon. In addition, the maximum strain in "toe region" (strainTP) was determined to describe the balance between growth of bone and muscle-tendon unit. RESULTS: No group difference was observed in length, cross-sectional area and strainTP among the groups. However, stiffness and Young's modulus in after PHV groups were significantly higher than those of elementary school boys and before PHV groups (p <= 0.05). CONCLUSIONS: These results indicate that mechanical properties of Achilles tendon change dramatically at and/or around PHV to increased stiffness. The widely believed assumption that muscle-tendon unit is passively stretched due to rapid bone growth in adolescence is not supported. PMID- 29177723 TI - Intimate Partner Violence, Cumulative Violence Exposure, and Mental Health Service Use. AB - Intimate partner violence (IPV) leaves victims with serious mental healthconsequences; some victims do not seek help even though they suffer from adverse mental health symptoms. Victims' use of mental health services seems to be affected by sociocultural factors and their history of experiences with violence. This study used the collaborative psychiatric epidemiology surveys to examine the effects of cumulative violence on IPV victims' mental health service use. The results showed that victims' mental health needs were the most prominent predictor of their use of mental health services, and that cumulative violence exposure also predicted mental health service use. PMID- 29177724 TI - Cost Analysis of Community Based Family Support of Patients with Severe Mental Illness. AB - Community-based family support is a new option to patients with severe mental illness in which the patient and a volunteer family meet on a regular basic. This study examined whether this support could reduce patients' use of psychiatric services. This matched case-control study included 86 patients with severe mental illness. 40 patients were offered the intervention: community-based family support intervention. Patients' use of psychiatric hospital services was followed from 2 years before to 2 years after the intervention using a difference-in difference analytical approach. Although community-based family support seemed to reduce hospital admission, the reduction in cost did not compensate the cost of the programme. However, this does not rule out the potential cost effectiveness, and future studies should assess the clinical benefits and cost effectiveness of community-based family support. The present study does not provide sufficient basis for recommending the general implementation of community-based family support. PMID- 29177725 TI - Stigma Towards Depression in Rural Ireland: A Qualitative Exploration. AB - The configuration of one's social environment influences the course and experience of depression. Research suggests that experiencing depression is associated with stigmatisation and the concomitant experiencing of discrimination across many facets of social life. This is identified as a particularly important factor in rural communities. Contemporary work is absent in relation to understanding the stigma towards depression in Ireland, and its manifestation in rural Ireland specifically. Evidence is presented which suggests that depression is a significant source of stigmatisation in this setting, and that entrenched views centring upon disability and fear are prevalent. PMID- 29177727 TI - Effects of shape, size, and pyrene doping on electronic properties of graphene nanoflakes. AB - Effects of size, shape, and pyrene doping on electronic properties of graphene nanoflakes (GNFs) were theoretically investigated using density functional theory method with PBE, B3PW91, and M06-2X functionals and cc-pVDZ basis set. Two shapes of zigzag GNFs, hexagonal (HGN) and rhomboidal (RGN), were considered. The energy band gap of GNF depends on shape and decreases with size. The HGN has larger band gap energy (1.23-3.96 eV) than the RGN (0.13-2.12 eV). The doping of pyrene and pyrene derivatives on both HGN and RGN was also studied. The adsorption energy of pyrene and pyrene derivatives on GNF does not depend on the shape of GNFs with energies between 21 and 27 kcal mol-1. The substituent on pyrene enhances the binding to GNF but the strength does not depend on electron withdrawing or donating capability. The doping by pyrene and pyrene derivatives also shifts the HOMO and LUMO energies of GNFs. Both positive (destabilizing) and negative (stabilizing) shifts on HOMO and LUMO of GNFs were seen. The direction and magnitude of the shift do not follow the electron withdrawing and donating capability of pyrene substituents. However, only a slight shift was observed for doped RGN. A shift of 0.19 eV was noticed for HOMO of HGN doped with 1 aminopyrene (pyNH2) and of 0.04 eV for LUMO of HGN doped with 1-pyrenecarboxylic acid (pyCOOH).

PMID- 29177728 TI - Prognostic value of pre-treatment 18F-FDG PET uptake for nasopharyngeal carcinoma. AB - PURPOSE: To evaluate the prognostic value of maximal standardized uptake values (SUVmax) from serial fluor-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in patients with nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS: Fifty-two patients with NPC who underwent 18F-FDG PET/CT scan before radiotherapy with/without chemotherapy were reviewed retrospectively. Twenty-seven patients (52%) were applied 3-D conformal radiotherapy and 25 patients (48%) applied intensity-modulated radiotherapy (IMRT). Fourteen (27%) patients were given neoadjuvant chemotherapy and forty four (84.6%) patients were given concomitant and adjuvant chemotherapy. RESULTS: Median follow-up time was 34 months (range 5.6-66.4 months). Forty-four (84.6%) patients were alive at last follow-up and eight (15.4%) had died. The best cut off value of the SUVmax for the primary tumor site (SUVmax-PT) was 13 and 9 for the lymph nodes (SUVmax-LN). Patients with SUVmax-PT >= 13.0 and SUVmax-LN >= 9 had a significantly higher risk for the development of the distant metastases (p = 0.044 and p = 0.038). DFS was affected in patients with SUVmax-PT >= 13 (log rank chi 2 = 2.54, p = 0.017) and was significantly lower in patients with SUVmax LN >= 9 for the lymph nodes (log rank chi 2 = 5.81, p = 0.013). OS was not affected by SUV levels. A multivariate Cox proportional hazard model of DFS included age (>= 40), SUVmax-LN (< 9), T stage (T1-2) and neoadjuvant chemotherapy are significantly better prognosis for the DFS. CONCLUSION: 18F-FDG PET/CT uptake before treatment, as determined by SUVmax, may be a valuable tool to evaluate prognosis in NPC patients. PMID- 29177729 TI - The effect of dietary energy and protein levels on body weight, size, and microflora of ostrich chicks. AB - The aim of this study was to evaluate the effect of different dietary energy and protein supplements on performance, weekly body sizes or body frame size, and microbiota of ostrich chicks during 2-9 weeks of age. Two metabolic energy levels of 2400 and 2600 kcal/kg live weight and three protein levels of 20, 22, and 24% were used. A total of 36 ostrich chickens (Struthio camelus) of the blue and black African breed were used. Body weight, 12 body measurements (i.e., circumference of the head, neck, breast, abdomen, thigh, body height, length of tail, list the other 5 here) and excretion of microbial population (Escherichia coli, Coliforms bacteria, and Lactobacillus bacteria) were measured. Mean body weight in each week of the experiment was generally the lowest when chicks were offered 2600 kcal/kg dietary energy and 24% protein. Of the 12 body measurements, the breast, abdomen, and thigh circumference and also body length were greater at the lower energy (2400 kcal/kg) and higher protein (24%) levels. Total Aerobic bacteria excretion was generally lower in response to the diet containing the higher level of energy. We conclude that ostrich chickens during 2-9 weeks of age can grow on diets that contain lower energy levels. PMID- 29177730 TI - Type IA DNA Topoisomerases: A Universal Core and Multiple Activities. AB - All the type IA topoisomerases display universal characteristics relying on a core region basically responsible for the transesterification and the strand passage reaction. First limited to the bacterial domain for a long time, these enzymes were further retrieved in Archaea and Eukarya as well. This is representative of an extremely ancient origin, probably due to an inheritance from the RNA world. As remaining evidence, some current topoisomerases IA have retained a RNA topoisomerase activity. Despite the presence of this core region in all of these TopoIAs, some differences exist and are originated from variable regions, located essentially within both extremities, conferring on them their specificities. During the last 2 decades the evidence of multiple activities and dedicated roles highlighted the importance of the topoisomerases IA. It is now obvious that topoisomerases IA are key enzymes involved in the maintenance of the genome stability. The discovery of these new activities was done thanks to the use of more accurate assays, based on new sophisticated DNA substrates. PMID- 29177731 TI - Topoisomerase I and Genome Stability: The Good and the Bad. AB - Topoisomerase I (Top1) resolves torsional stress that accumulates during transcription, replication and chromatin remodeling by introducing a transient single-strand break in DNA. The cleavage activity of Top1 has opposing roles, either promoting or destabilizing genome integrity depending on the context. Resolution of transcription-associated negative supercoils, for example, prevents pairing of the nascent RNA with the DNA template (R-loops) as well as DNA secondary structure formation. Reduced Top1 levels thus enhance CAG repeat contraction, somatic hypermutation, and class switch recombination. Actively transcribed ribosomal DNA is also destabilized in the absence of Top1, reflecting the importance of Top1 in ensuring efficient transcription. In terms of promoting genome instability, an aborted Top1 catalytic cycle stimulates deletions at short tandem repeats and the enzyme's transesterification activity supports illegitimate recombination. Finally, Top1 incision at ribonucleotides embedded in DNA generates deletions in tandem repeats, and induces gross chromosomal rearrangements and mitotic recombination. PMID- 29177732 TI - DNA Topoisomerases as Targets for Antibacterial Agents. AB - DNA topoisomerases are proven therapeutic targets of antibacterial agents. Quinolones, especially fluoroquinolones, are the most successful topoisomerase targeting antibacterial drugs. These drugs target type IIA topoisomerases in bacteria. Recent structural and biochemical studies on fluoroquinolones have provided the molecular basis for both their mechanism of action, as well as the molecular basis of bacterial resistance. Due to the development of drug resistance, including fluoroquinolone resistance, among bacterial pathogens, there is an urgent need to discover novel antibacterial agents. Recent advances in topoisomerase inhibitors may lead to the development of novel antibacterial drugs that are effective against fluoroquinolone-resistant pathogens. They include type IIA topoisomerase inhibitors that either interact with the GyrB/ParE subunit or form nick-containing ternary complexes. In addition, several topoisomerase I inhibitors have recently been identified. Thus, DNA topoisomerases remain important targets of antibacterial agents. PMID- 29177733 TI - DNA Supercoiling Measurement in Bacteria. AB - DNA supercoiling plays critical roles in several essential DNA metabolic pathways, such as replication, transcription and recombination. Typically plasmid DNA molecules are used to measure DNA supercoiling status inside bacterial cells. In this chapter, we describe how to isolate plasmid DNA molecules from E. coli cells and determine DNA supercoiling density by 1% agarose gel electrophoresis containing chloroquine using plasmid pACYC184 as an example. PMID- 29177734 TI - DNA Catenation Reveals the Dynamics of DNA Topology During Replication. AB - Two-dimensional agarose gel electrophoresis is the method of choice to identify and quantify all the topological forms DNA molecules can adopt in vivo. Here we describe the materials and protocols needed to analyze catenanes, the natural outcome of DNA replication, in Saccharomyces cerevisiae. We describe the formation of pre-catenanes during replication and how inhibition of topoisomerase 2 leads to the accumulation of intertwined sister duplexes. This knowledge is essential to determine how replication forks blockage or pausing affects the dynamic of DNA topology during replication. PMID- 29177735 TI - Mapping E. coli Topoisomerase IV Binding and Activity Sites. AB - This methods article described a protocol aiming at mapping E. coli Topoisomerase IV (Topo IV) binding and cleavage activity sites on the genome. The approach is readily applicable to any Type II topoisomerase on a broad variety of gram positive and gram-negative bacterial species. Conventional ChIP-seq of flag tagged Topo IV subunits and a novel method aimed at trapping only DNA bound to active Topo IV (called NorfliP) are described. NorfliP relies on the ability of norfloxacin, a quinolone drug, to cross-link the 5' ends of the DNA breaks with the catalytic tyrosine of bacterial Type II topoisomerases. These methods give complementary results and their combination brought important insights on both the function and regulation of Topo IV. PMID- 29177736 TI - The Use of Psoralen Photobinding to Study Transcription-Induced Supercoiling. AB - Proteins manipulating intracellular DNA necessarily impart torsional stress, which redistributes across the DNA. Overtwisting and undertwisting of the double helix result in the manifestation of positive and negative DNA supercoiling. A growing body of evidence indicates that DNA topology is an important player in the key regulatory steps of genome function, highlighting the need for biochemical techniques to detect dynamic changes in the DNA structure. Psoralen binding to DNA in vivo is proportional to the level of supercoiling, providing an excellent probe for the topological state of nuclear DNA. Here we describe a psoralen-based methodology to detect transcription-induced DNA supercoiling genome-wide. The DNA samples generated with this approach can be hybridized to microarray platforms or high-throughput sequenced to provide a topological snapshot of the whole genome. PMID- 29177737 TI - Immunoprecipitation of RNA:DNA Hybrids from Budding Yeast. AB - During transcription, the nascent transcript behind an elongating RNA polymerase (RNAP) can invade the DNA duplex and hybridize with the complementary DNA template strand, generating a three-stranded "R-loop" structure, composed of an RNA:DNA duplex and an unpaired non-template DNA strand. R-loops can be strongly associated with actively transcribed loci by all RNAPs including the mitochondrial RNA polymerase (mtRNAP). In this chapter, we describe two protocols for the detection of RNA:DNA hybrids in living budding yeast cells, one that uses conventional chromatin immunoprecipitation (ChIP-qPCR) and one that uses DNA:RNA immunoprecipitation (DRIP-qPCR). Both protocols make use of the S9.6 antibody, which is believed to recognize the intermediate A/B helical RNA:DNA duplex conformation, with no sequence specificity. PMID- 29177738 TI - Detection of oriC-Independent Replication in Escherichia coli Cells. AB - In bacteria, replication of the chromosome is normally initiated following the binding of DnaA proteins to the oriC region. However, under certain circumstances, replication can also be initiated independent of the oriC/DnaA system. This is the case, for example, in Escherichia coli cells lacking RNase HI (rnha mutants) or type 1A topoisomerase activity (topA topB mutants). Here, we present a protocol in which replication from the oriC/DnaA system is first inhibited by the addition of the protein synthesis inhibitor, spectinomycin, to exponentially growing bacterial cell cultures. The thymidine analog, 5-ethynyl-2' deoxyurdine (EdU) is then added to the cells, and after 1 h the cells are fixed and the Alexa Fluor(r) 488 dye is conjugated to EdU by the click-iT(r) reaction. The oriC-independent replication is detected in fixed cells by flow cytometry and can be visualized by fluorescence microscopy. PMID- 29177739 TI - Single-Molecule Magnetic Tweezer Analysis of Topoisomerases. AB - Magnetic tweezers (MT) provide a powerful single-molecule approach to study the mechanism of topoisomerases, giving the experimenter the ability to change and read out DNA topology in real time. By using diverse DNA substrates, one can study different aspects of topoisomerase function and arrive at a better mechanistic understanding of these fascinating enzymes. Here we describe methods for the creation of three different DNA substrates used in MT experiments with topoisomerases: double-stranded DNA (dsDNA) tethers, "braided" (intertwined or catenated) DNA tether pairs, and dsDNA tethers with single-stranded DNA (ssDNA) regions. Additionally, we discuss how to build flow cells for bright-field MT microscopy, as well as how to noncovalently attach anti-digoxigenin to the coverslip surface for tethering digoxigenin-labeled DNAs. Finally, we describe procedures for the identification of a suitable DNA substrate for MT study and data collection. PMID- 29177740 TI - Synthesis of Hemicatenanes for the Study of Type IA Topoisomerases. AB - Hemicatenane is a structure that forms when two DNA duplexes are physically linked through a single-stranded crossover. It is proposed to be an intermediate resulting from double Holliday junction (dHJ) dissolution, repair of replication stalled forks and late stage replication. Our previous study has shown that hemicatenane can be synthesized and dissolved in vitro by hyperthermophilic type IA topoisomerases. Here we present the protocol of hemicatenane synthesis and its structure detection by 2D agarose gel electrophoresis. The generated product can be used as a substrate to study the biochemical mechanism of hemicatenane processing reactions. PMID- 29177741 TI - An Assay for Detecting RNA Topoisomerase Activity. AB - RNA topoisomerase activity has recently been detected in multiple Type IA DNA topoisomerases from all three domains of life: bacteria, archaea, and eukarya. Many, but not all, Type IA topoisomerases are found to possess activities for not only DNA, but also RNA, suggesting that they may solve topological problems for both types of nucleic acids. Here we describe a detailed assay used by our group to detect RNA topoisomerase activity for many Type IA topoisomerases. We discuss the strategy, experimental procedures, troubleshooting, and limitations for this assay. PMID- 29177742 TI - Studying TDP1 Function in DNA Repair. AB - Topoisomerase poisons act by inducing abortive topoisomerase reactions, which generate stable protein-DNA breaks (PDBs) that interfere with transcription elongation and progression of replication forks. In vertebrates, Tyrosyl-DNA phosphodiesterase 1 (TDP1) plays a major role in removal of topoisomerase 1 associated PDBs in the nucleus and mitochondria by hydrolyzing the 3' phosphotyrosine bond. Depletion of TDP1 sensitizes tumor cells with defective DNA repair capacity to the genotoxic effect of TOP1 poisons, while homozygous mutation of the catalytic residue of TDP1 is associated with cerebellar degeneration and ataxia. We describe here two fluorescence based biochemical assays for measuring TDP1 phosphodiesterase activity in cellular lysates. The Gyrasol assay is sensitive, high-throughput, and useful for screening potential TDP1 inhibitors or cell lines that are likely to develop resistance to TOP1 poisons. The gel-shift assay is low cost and simple to set up, and is also suitable for screening cell lines that are likely to develop resistance to TOP1 poisons, as well as for diagnostic screening for individuals with hereditary ataxias. PMID- 29177743 TI - Topoisomerase II Chromatin Immunoprecipitation. AB - Chromatin immunoprecipitation is a method to isolate a protein of interest coupled to DNA following cross-linking with formaldehyde and to quantify the relative abundance or occupancy of the protein at specific genomic loci. After immunoprecipitation of protein-DNA complexes protein-DNA cross-links are reversed and the DNA is extracted. Various methods exist to identify binding sites and determine relative occupancy of the protein of interest; these include quantitative PCR, probing microarrays or sequencing the isolated DNA (ChIP-seq). This chapter details the method of chromatin immunoprecipitation of TOP2 to the point of DNA extraction from the precipitated protein-DNA complexes. PMID- 29177744 TI - Analyzing Mitotic Chromosome Structural Defects After Topoisomerase II Inhibition or Mutation. AB - For analyzing chromosome structural defects that result from topoisomerase II (topo II) dysfunction we have adapted classical cell cycle experiments, classical cytological techniques and the use of a potent topo II inhibitor (ICRF-193). In this chapter, we describe in detail the protocols used and we discuss the rational for our choice and for the adaptations applied. We clarify in which cell cycle stages each of the different chromosomal aberrations induced by inhibiting topo II takes place: lack of chromosome segregation, undercondensation, lack of sister chromatid resolution, and lack of chromosome individualization. We also put these observations into the context of the two topo II-dependent cell cycle checkpoints. In addition, we have devised a system to analyze phenotypes that result when topo II is mutated in human cells. This serves as an alternative strategy to the use of topo II inhibitors to perturb topo II function. PMID- 29177745 TI - Monitoring the DNA Topoisomerase II Checkpoint in Saccharomyces cerevisiae. AB - Topoisomerase II activity is crucial to maintain genome stability through the removal of catenanes in the DNA formed during DNA replication and scaffolding the mitotic chromosome. Perturbed Topo II activity causes defects in chromosome segregation due to persistent catenations and aberrant DNA condensation during mitosis. Recently, novel top2 alleles in the yeast Saccharomyces cerevisiae revealed a checkpoint control which responds to perturbed Topo II activity. Described in this chapter are protocols for assaying the phenotypes seen in top2 mutants on a cell biological basis in live cells: activation of the Topo II checkpoint using spindle morphology, chromosome condensation using fluorescently labeled chromosomal loci and cell cycle progression by flow cytometry. Further characterization of this novel checkpoint is warranted so that we can further our understanding of the cell cycle, genomic stability, and the possibility of identifying novel drug targets. PMID- 29177746 TI - Studying Topoisomerase 1-Mediated Damage at Genomic Ribonucleotides. AB - Ribonucleotides incorporated into DNA by the DNA polymerases can be incised by Topoisomerase 1 (Top1) to initiate removal of ribonucleotides from the genome. This Top1-dependent ribonucleotide removal has been demonstrated to result in multiple forms of genome instability in yeast. Here, we describe both quantitative and qualitative assays to identify mutations and other forms of DNA damage resulting from Top1-cleavage at unrepaired genomic ribonucleotides. PMID- 29177747 TI - A Fluorescence-Based Assay for Identification of Bacterial Topoisomerase I Poisons. AB - Bacterial Topoisomerase I is a potential target for the identification of novel topoisomerase poison inhibitors that could provide leads for a new class of antibacterial compounds. Here we describe in detail a fluorescence-based cleavage assay that is successfully used in HTS for the discovery of bacterial topoisomerase Iota poisons. PMID- 29177748 TI - Fluoroquinolone-Gyrase-DNA Cleaved Complexes. AB - The quinolones are potent antibacterials that act by forming complexes with DNA and either gyrase or topoisomerase IV. These ternary complexes, called cleaved complexes because the DNA moiety is broken, block replication, transcription, and bacterial growth. Cleaved complexes readily form in vitro when gyrase, plasmid DNA, and quinolone are combined and incubated; complexes are detected by the linearization of plasmid DNA, generally assayed by gel electrophoresis. The stability of the complexes can be assessed by treatment with EDTA, high temperature, or dilution to dissociate the complexes and reseal the DNA moiety. Properties of the complexes are sensitive to quinolone structure and to topoisomerase amino acid substitutions associated with quinolone resistance. Consequently, studies of cleaved complexes can be used to identify improvements in quinolone structure and to understand the biochemical basis of target-based resistance. Cleaved complexes can also be detected in quinolone-treated bacterial cells by their ability to rapidly block DNA replication and to cause chromosome fragmentation; they can even be recovered from lysed cells following CsCl density gradient centrifugation. Thus, in vivo and cell-fractionation tests are available for assessing the biological relevance of work with purified components. PMID- 29177749 TI - Detection of Topoisomerase Covalent Complexes in Eukaryotic Cells. AB - DNA topoisomerases carry out topological transformations of DNA by introducing transient DNA breaks. The covalent intermediate of topoisomerase reactions include the topoisomerase protein covalently bound to DNA by a phosphotyrosine intermediate. Anti-cancer drugs that target topoisomerases typically trap the covalent intermediate, and generate cytotoxic enzyme dependent DNA damage. More recently, structural alterations in DNA such as DNA damage have also been shown to trap covalent intermediates of topoisomerase reactions. Understanding the action of drugs that target topoisomerases as well as determining the importance of trapped topoisomerases on genome stability requires assays that can accurately and sensitively measure levels of topoisomerase/DNA complexes. This chapter describes two approaches that have been developed to quantitate topoisomerase DNA complexes. These assays termed ICE (in vivo complex of enzymes) and RADAR (rapid approach to DNA adduct recovery) rely on isolation of genomic DNA under conditions that preserve proteins covalently bound to DNA. Covalently bound proteins are then quantitated using antibodies directed against specific topoisomerases. We describe assays in both mammalian cells and the yeast Saccharomyces cerevisiae that can measure topoisomerase/DNA covalent complexes, and give examples that can be used to enhance the quantitative reliability of these assays. PMID- 29177750 TI - Visualization and Quantification of Topoisomerase-DNA Covalent Complexes Using the Trapped in Agarose Immunostaining (TARDIS) Assay. AB - The TARDIS assay was originally developed as a means of detecting and quantifying melphalan and cisplatin DNA adducts at the single cell level, but it has since been adapted to quantify topoisomerase DNA complexes that result from the actions of topoisomerase poisons and this is currently the main use of the assay. The method employs sensitive immunofluorescent detection to quantify topoisomerase molecules covalently coupled to DNA in what are often referred to as cleavage complexes. Free topoisomerase molecules, and other cellular constituents are first removed using salt-detergent extraction of agarose-embedded, unfixed cells. Using these stringent extraction conditions, genomic DNA remains in place in the agarose as "nuclear ghosts," and any covalent attached molecules can be detected and quantified by immunofluorescence with a low background. PMID- 29177751 TI - Study of Plasmid-Mediated Quinolone Resistance in Bacteria. AB - Plasmid-mediated quinolone resistance (PMQR) involves genes for proteins that protect the quinolone targets, an enzyme that inactivates certain quinolones as well as aminoglycosides, and pumps that efflux quinolones. Quinolone susceptibility is reduced by these mechanisms but not to the level of clinical resistance unless chromosomal mutations are also present. PCR primers and conditions for PMQR gene detection are described as well as how to establish a plasmid location. PMID- 29177752 TI - Bacterial Shifts in Nutrient Solutions Flowing Through Biofilters Used in Tomato Soilless Culture. AB - In soilless culture, slow filtration is used to eliminate plant pathogenic microorganisms from nutrient solutions. The present study focused on the characterization and the potential functions of microbial communities colonizing the nutrient solutions recycled on slow filters during a whole cultivation season of 7 months in a tomato growing system. Bacterial microflora colonizing the solutions before and after they flew through the columns were studied. Two filters were amended with Pseudomonas putida (P-filter) or Bacillus cereus strains (B-filter), and a third filter was a control (C-filter). Biological activation of filter unit through bacterial amendment enhanced very significantly filter efficacy against plant potential pathogens Pythium spp. and Fusarium oxysporum. However, numerous bacteria (103-104 CFU/mL) were detected in the effluent solutions. The community-level physiological profiling indicated a temporal shift of bacterial microflora, and the metabolism of nutrient solutions originally oriented towards carbohydrates progressively shifted towards degradation of amino acids and carboxylic acids over the 7-month period of experiment. Single-strand conformation polymorphism fingerprinting profiles showed that a shift between bacterial communities colonizing influent and effluent solutions of slow filters occurred. In comparison with influent, 16S rDNA sequencing revealed that phylotype diversity was low in the effluent of P- and C-filters, but no reduction was observed in the effluent of the B-filter. Suppressive potential of solutions filtered on a natural filter (C-filter), where the proportion of Proteobacteria (alpha- and beta-) increased, whereas the proportion of uncultured candidate phyla rose in P- and B-filters, is discussed. PMID- 29177753 TI - Microbial Reduction of Fe(III) and SO42- and Associated Microbial Communities in the Alluvial Aquifer Groundwater and Sediments. AB - Agricultural demands continuously increased use of groundwater, causing drawdown of water table and need of artificial recharge using adjacent stream waters. River water intrusion into groundwater can alter the geochemical and microbiological characteristics in the aquifer and subsurface. In an effort to investigate the subsurface biogeochemical activities before operation of artificial recharge at the test site, established at the bank of Nakdong River, Changwon, South Korea, organic carbon transported from river water to groundwater was mimicked and the effect on the indigenous microbial communities was investigated with the microcosm incubations of the groundwater and subsurface sediments. Laboratory incubations indicated microbial reduction of Fe(III) and sulfate. Next-generation Illumina MiSeq sequences of V4 region of 16S rRNA gene provided that the shifts of microbial taxa to Fe(III)-reducing and/or sulfate reducing microorganisms such as Geobacter, Albidiferax, Desulfocapsa, Desulfuromonas, and Desulfovibrio were in good correlation with the sequential flourishment of microbial reduction of Fe(III) and sulfate as the incubations progressed. This suggests the potential role of dissolved organic carbons migrated with the river water into groundwater in the managed aquifer recharge system on the indigenous microbial community composition and following alterations of subsurface biogeochemistry and microbial metabolic activities. PMID- 29177755 TI - Are cytological parameters of maize landraces (Zea mays ssp. mays) adapted along an altitudinal cline? AB - The Northwestern Argentina (NWA) highland region is one of the southernmost areas of native maize cultivation. We studied variations of different cytological parameters, such as DNA contents, presence/absence of B chromosomes (Bs), and number and sequence composition of heterochromatic knobs in ten accessions of four maize landraces growing along a broad altitudinal cline in NWA. The aim of this work was to assess variations in cytological parameters and their relationship with the crop altitude of cultivation, in an adaptive context. The A DNA content of the A chromosome complements showed 40% of difference between the lowest (4.5 pg) and the highest (6.3 pg) 2C value. This variation could be attributed to differences in number and size of heterochromatic knobs. Fluorescent in situ hybridization studies revealed the sequence composition of each knob, with a higher proportion of knobs composed of 180-bp repeats rather than TR-1 repeats, in all accessions. We also found numerical polymorphisms and the highest frequency of Bs reported in maize to this date. These results lead us to propose that the frequencies and doses of Bs are influenced by the landrace genotypical make-up. The Bs might be maintained in higher frequencies in those accessions having lower heterochromatin content, so as to preserve an optimal nucleotype. Furthermore, selective forces acting along the altitudinal gradient might be modulating the cytological parameters studied, as suggested by the significant correlations found among them. PMID- 29177754 TI - A review of biomarkers in peri-miniscrew implant crevicular fluid (PMICF). AB - BACKGROUND: The temporary anchorage devices (TADs) which include miniscrew implants (MSIs) have evolved as useful armamentarium in the management of severe malocclusions and assist in complex tooth movements. Although a multitude of factors is responsible for the primary and secondary stability of miniscrew implants, contemporary research highlights the importance of biological interface of MSI with bone and soft tissue in augmenting the success of implants. The inflammation and remodeling associated with MSI insertion or loading are reflected through biomarkers in peri-miniscrew implant crevicular fluid (PMICF) which is analogous to the gingival crevicular fluid. Analysis of biomarkers in PMICF provides indicators of inflammation at the implant site, osteoclast differentiation and activation, bone resorption activity and bone turnover. The PMICF for assessment of these biomarkers can be collected non-invasively via paper strips, periopaper or micro capillary pipettes and analysed by enzyme linked immunosorbent assay (ELISA) or immunoassays. The markers and mediators of inflammation have been previously studied in relation to orthodontic tooth movement include interleukins (IL-1beta, IL-2, IL-6 and IL-8), growth factors and other proteins like tumour necrosis factor (TNF-alpha), receptor activator of nuclear factor kappa-B ligand (RANKL), chondroitin sulphate (CS) and osteoprotegerin (OPG). Studies have indicated that successful and failed MSIs have different concentrations of biomarkers in PMICF. However, there is a lack of comprehensive information on this aspect of MSIs. Therefore, a detailed review was conducted on the subject. RESULTS: A literature search revealed six relevant studies: two on IL-1beta; one on IL-2, IL-6 and IL-8; one on TNF-alpha; one on CS; and one on RANKL/OPG ratio. One study showed an increase in IL-1beta levels upon MSI loading, peak in 24 hours (h), followed by a decrease in 21 days to reach baseline in 300 days. A 6.87% decrease in IL-2 levels was seen before loading and a 5.97% increase post-loading. IL-8 showed a 6.31% increase after loading and IL-6 increased by 3.08% before MSI loading and 15.06% after loading. RANKL/OPG ratio increased in loaded compared to unloaded MSIs. CONCLUSIONS: Cytokines (mainly ILs and TNF-alpha) and RANKL/OPG ratio showed alteration in PMICF levels upon loading of MSIs as direct or indirect anchorage.

AB - Leuconostoc pseudomesenteroides 607, isolated from persimmon fruit, was found to have high inhibitory activity against Listeria monocytogenes and several other Gram-positive bacteria. Inhibitory substances were purified from culture supernatant by ion-exchange chromatography, Sep-Pak C18 cartridge, and reverse phase high-performance liquid chromatography (RP-HPLC). Two antibacterial peptides were observed during the purification procedures. One of these peptides had a molecular size of 4623.05 Da and a partial N-terminal amino acid sequence of NH2-KNYGNGVHxTKKGxS, in which the YGNGV motif is specific for class IIa bacteriocins. A BLAST search revealed that this bacteriocin was similar to leucocin C from Leuconostoc mesenteroides. Leucocin C-specific primers were designed and a single PCR product was amplified. Analysis of the nucleotide sequence has revealed a putative peptide differing by only one amino acid residue from the sequence of leucocin C. No identical peptide or protein has been reported in the literature, and this peptide, termed leucocin C-607, was therefore considered to be a new variant of leucocin C produced by Leuc. pseudomesenteroides 607. Another antibacterial peptide purified from the same culture supernatant had a molecular size of 3007.7 or 3121.97 Da. However, detailed information regarding this second peptide remains to be determined. Distinct characteristics, such as heat stability and inhibitory spectrum, were observed for the two bacteriocins produced by Leuc. pseudomesenteroides 607. These results suggested that Leuc. pseudomesenteroides 607 produces leucocin C 607 along with another unknown bacteriocin. PMID- 29177757 TI - The role of dermoscopy in the diagnosis of distal lateral subungual onychomycosis. AB - Recently dermoscopic patterns, that can be useful in the diagnosis of distal and lateral subungual onychomycosis, were identified. In this study, we aimed to determine the frequency of the defined patterns so far and additionally to identify other patterns that were observed and to investigate the place of these patterns in the diagnosis of Distal Lateral Subungual Onychomycosis (DLSO) in the dermoscopic examination of the patients with pre-diagnosis of DLSO. Patients admitted dermatology outpatient clinic of Haydarpasa Numune Training and Research Hospital with the complaint of nail disturbance suspicious for DLSO (97 patients) between the August 2015 and February 2016. Clinical and dermoscopic photographs of the cases with a pre-diagnosis of DLSO were taken and their nails were cut for pathological examination and culture. In hematoxylin and eosin, and periodic acid schiff examination, hyphe and/or spore were observed in 134 (65.4%) and fungal growth was detected in 99 (48.3%) of the nail samples. As a result of logistic regression model analysis, the p values of the 'ruin appearance', 'homogeneous leukonychia', 'punctate leukonychia', and 'black discoloration' patterns preserved their statistical significance (p = 0.015, p = 0.009, p = 0.026, p = 0.040, respectively). We believe that in nail disorders clinically resembling DLSO patients, the presence of dermoscopic patterns of ruin appearance, homogenous leuconychia, punctate leuconychia, and black discoloration strongly supports the clinical diagnosis of DLSO.

AB - This paper introduces a case study at a community hospital to develop a predictive model to quantify readmission risks for patients with chronic obstructive pulmonary disease (COPD), and use it to support decision making for appropriate incentive-based interventions. Data collected from the community hospital's database are analyzed to identify risk factors and a logistic regression model is developed to predict the readmission risk within 30 days post discharge of an individual COPD patient. By targeting on the high-risk patients, we investigate the implementability of the incentive policy which encourages patients to take interventions and helps them to overcome the compliance barrier. Specifically, the conditions and scenarios are identified for either achieving the desired readmission rate while minimizing the total cost, or reaching the lowest readmission rate under incentive budget constraint. Currently, such models are under consideration for a pilot study at the community hospital. PMID- 29177760 TI - Introduction. AB - In this special volume on "Chromatin regulation of early embryonic lineage specification," five leaders in the field of mammalian preimplantation embryo development provide their own perspectives on key molecular and cellular processes that mediate lineage formation during the first week of life. The first cell-fate decision involves the formation of the pluripotent inner cell mass (ICM) and extraembryonic trophectoderm (TE). The second cell-fate choice encompasses the transformation of ICM into extraembryonic primitive endoderm (PE) and pluripotent epiblast. The processes, which occur during the period of preimplantation development, serve as the foundation for subsequent developmental events such as implantation, placentation, and gastrulation. The mechanisms that regulate them are complex and involve many different factors operating spatially and temporally over several days to modulate embryonic chromatin structure, impose cellular polarity, and direct distinct gene expression programs in the first cell lineages. PMID- 29177759 TI - Personality and eating and weight disorders: an open research challenge. PMID- 29177761 TI - Chromatin Remodelling Proteins and Cell Fate Decisions in Mammalian Preimplantation Development. AB - The very first cell divisions in mammalian embryogenesis produce a ball of cells, each with the potential to form any cell in the developing embryo or placenta. At some point, the embryo produces enough cells that some are located on the outside of the embryo, while others are completely surrounded by other cells. It is at this point that cells undergo the very first lineage commitment event: outer cells form the trophectoderm and lose the potential to form embryonic lineages, while inner cells form the Inner Cell Mass, which retain embryonic potential. Cell identity is defined by gene expression patterns, and gene expression is largely controlled by how the DNA is packaged into chromatin. A number of protein complexes exist which are able to use the energy of ATP to remodel chromatin: that is, to alter the nucleosome topology of chromatin. Here, we summarise the evidence that chromatin remodellers play essential roles in the successful completion of preimplantation development in mammals and describe recent efforts to understand the molecular mechanisms through which chromatin remodellers facilitate the successful completion of the first cell fate decisions in mammalian embryogenesis. PMID- 29177762 TI - CHD1 Controls Cell Lineage Specification Through Zygotic Genome Activation. AB - In mammals, the processes spanning from fertilization to the generation of a new organism are very complex and are controlled by multiple genes. Life begins with the encounter of eggs and spermatozoa, in which gene expression is inactive prior to fertilization. After several cell divisions, cells arise that are specialized in implantation, a developmental process unique to mammals. Cells involved in the establishment and maintenance of implantation differentiate from totipotent embryos, and the remaining cells generate the embryo proper. Although this process of differentiation, termed cell lineage specification, is supported by various gene expression networks, many components have yet to be identified. Moreover, despite extensive research it remains unclear which genes are controlled by each of the factors involved. Although it has become clear that epigenetic factors regulate gene expression, elucidation of the underlying mechanisms remains challenging. In this chapter, we propose that the chromatin remodeling factor CHD1, together with epigenetic factors, is involved in a subset of gene expression networks involved in processes spanning from zygotic genome activation to cell lineage specification. PMID- 29177763 TI - Transcriptional Regulation and Genes Involved in First Lineage Specification During Preimplantation Development. AB - The successful development from a single-cell zygote into a complex multicellular organism requires precise coordination of multiple cell-fate decisions. The very first of these is lineage specification into the inner cell mass (ICM) and trophectoderm (TE) during mammalian preimplantation development. In mouse embryos, transcription factors (TFs) such as Oct4, Sox2, and Nanog are enriched in cells of ICM, which gives rise to the fetus and yolk sac. Conversely, TFs such as Cdx2 and Eomes become highly upregulated in TE, which contribute to the placenta. Here, we review the current understanding of key transcriptional control mechanisms and genes responsible for these distinct differences during the first cell lineage specification. In particular, we highlight recent insights gained through advances in genome manipulation, live imaging, single-cell transcriptomics, and loss-of-function studies. PMID- 29177765 TI - XEN and the Art of Stem Cell Maintenance: Molecular Mechanisms Maintaining Cell Fate and Self-Renewal in Extraembryonic Endoderm Stem (XEN) Cell Lines. AB - The extraembryonic endoderm is one of the first cell types specified during mammalian development. This extraembryonic lineage is known to play multiple important roles throughout mammalian development, including guiding axial patterning and inducing formation of the first blood cells during embryogenesis. Moreover, recent studies have uncovered striking conservation between mouse and human embryos during the stages when extraembryonic endoderm cells are first specified, in terms of both gene expression and morphology. Therefore, mouse embryos serve as an excellent model for understanding the pathways that maintain extraembryonic endoderm cell fate. In addition, self-renewing multipotent stem cell lines, called XEN cells, have been derived from the extraembryonic endoderm of mouse embryos. Mouse XEN cell lines provide an additional tool for understanding the basic mechanisms that contribute to maintaining lineage potential, a resource for identifying how extraembryonic ectoderm specifies fetal cell types, and serve as a paradigm for efforts to establish human equivalents. Given the potential conservation of essential extraembryonic endoderm roles, human XEN cells would provide a considerable advance. However, XEN cell lines have not yet been successfully derived from human embryos. Given the potential utility of human XEN cell lines, this chapter focuses on reviewing the mechanisms known to govern the stem cell properties of mouse XEN, in hopes of facilitating new ways to establish human XEN cell lines. PMID- 29177764 TI - ROCK and RHO Playlist for Preimplantation Development: Streaming to HIPPO Pathway and Apicobasal Polarity in the First Cell Differentiation. AB - In placental mammalian development, the first cell differentiation produces two distinct lineages that emerge according to their position within the embryo: the trophectoderm (TE, placenta precursor) differentiates in the surface, while the inner cell mass (ICM, fetal body precursor) forms inside. Here, we discuss how such position-dependent lineage specifications are regulated by the RHOA subfamily of small GTPases and RHO-associated coiled-coil kinases (ROCK). Recent studies in mouse show that activities of RHO/ROCK are required to promote TE differentiation and to concomitantly suppress ICM formation. RHO/ROCK operate through the HIPPO signaling pathway, whose cell position-specific modulation is central to establishing unique gene expression profiles that confer cell fate. In particular, activities of RHO/ROCK are essential in outside cells to promote nuclear localization of transcriptional co-activators YAP/TAZ, the downstream effectors of HIPPO signaling. Nuclear localization of YAP/TAZ depends on the formation of apicobasal polarity in outside cells, which requires activities of RHO/ROCK. We propose models of how RHO/ROCK regulate lineage specification and lay out challenges for future investigations to deepen our understanding of the roles of RHO/ROCK in preimplantation development. Finally, as RHO/ROCK may be inhibited by certain pharmacological agents, we discuss their potential impact on human preimplantation development in relation to fertility preservation in women. PMID- 29177766 TI - Effect of solute immobilization on the stability problem within the fractional model in the solute analog of the Horton-Rogers-Lapwood problem. AB - The paper is devoted to the linear stability analysis within the solute analogue of the Horton-Rogers-Lapwood (HRL) problem. The solid nanoparticles are treated as solute within the continuous approach. Therefore, we consider the infinite horizontal porous layer saturated with a mixture (carrier fluid and solute). Solute transport in porous media is very often complicated by solute immobilization on a solid matrix of porous media. Solute immobilization (solute sorption) is taken into account within the fractal model of the MIM approach. According to this model a solute in porous media immobilizes within random time intervals and the distribution of such random variable does not have a finite mean value, which has a good agreement with some experiments. The solute concentration difference between the layer boundaries is assumed as constant. We consider two cases of horizontal external filtration flux: constant and time modulated. For the constant flux the system of equations that determines the frequency of neutral oscillations and the critical value of the Rayleigh-Darcy number is derived. Neutral curves of the critical parameters on the governing parameters are plotted. Stability maps are obtained numerically in a wide range of parameters of the system. We have found that taking immobilization into account leads to an increase in the critical value of the Rayleigh-Darcy number with an increase in the intensity of the external filtration flux. The case of weak time-dependent external flux is investigated analytically. We have shown that the modulated external flux leads to an increase in the critical value of the Rayleigh-Darcy number and a decrease in the critical wave number. For moderate time-dependent filtration flux the differential equation with Caputo fractional derivatives has been obtained for the description of the behavior near the convection instability threshold. This equation is analyzed numerically by the Floquet method; the parametric excitation of convection is observed. PMID- 29177769 TI - Mutual interactions between telomere heterogeneity and cell culture growth dynamics shape stochasticity of cell aging. AB - Mathematical modeling and computational simulations are often used to explain the stochastic nature of cell aging. The models published thus far are based on the molecular mechanisms of telomere biology and how they dictate the dynamics of cell culture proliferation. However, the influence of cell growth conditions on telomere dynamics has been widely overlooked. These conditions include interactions with surrounding cells through contact inhibition, gradual accumulation of non-dividing cells, culture propagation and other cell culture maintenance factors. In order to follow the intrinsic growth dynamics of normal human fibroblasts we employed the fluorescent dye DiI and FACS analysis which can distinguish cells that undergo different numbers of divisions within culture. We observed rapid generation of cell subpopulations undergoing from 0 to 9 divisions within growing cultures at each passage analyzed. These large differences in number of divisions among individual cells guarantee a strong impact on generation of telomere length heterogeneity in normal cell cultures and suggest that culture conditions should be included in future modeling of cell senescence. PMID- 29177768 TI - Familial Parkinson's Disease-Associated L166P Mutant DJ-1 is Cleaved by Mitochondrial Serine Protease Omi/HtrA2. AB - Parkinson's disease (PD) is the most common neurodegenerative movement disorder. Mutations in the DJ-1, including L166P, are responsible for recessive early-onset PD. Many lines of evidence have shown that L166P is not only a loss-of-function mutant, but also a pro-apoptotic-like protein that results in mitochondrial dysfunction. L166P has been reported to be unstable and to mislocalize to mitochondria. However, the mechanisms underlying the instability of L166P compared to wild-type DJ-1 remain largely unknown. Here, we showed that Omi/HtrA2, a mitochondrial serine protease that has also been linked to the pathogenesis of PD, contributed to L166P instability. Omi directly interacted with and cleaved L166P in mitochondria to decrease the L166P level. However, Omi did not bind and cleave wild-type DJ-1. Moreover, Omi cleaved L166P at both serine residues 3 and 121, while L166P-induced cell death under H2O2 treatment was alleviated by over-expression of Omi. Our data reveal a bridge between DJ-1 and Omi, two PD-associated genetic factors, which contributes to our understanding of the pathogenesis of PD. PMID- 29177767 TI - Membrane Aging as the Real Culprit of Alzheimer's Disease: Modification of a Hypothesis. AB - Our previous studies proposed that Alzheimer's disease (AD) is a metabolic disorder and hypothesized that abnormal brain glucose metabolism inducing multiple pathophysiological cascades contributes to AD pathogenesis. Aging is one of the great significant risk factors for AD. Membrane aging is first prone to affect the function and structure of the brain by impairing glucose metabolism. We presume that risk factors of AD, including genetic factors (e.g., the apolipoprotein E epsilon4 allele and genetic mutations) and non-genetic factors (such as fat, diabetes, and cardiac failure) accelerate biomembrane aging and lead to the onset and development of the disease. In this review, we further modify our previous hypothesis to demonstrate "membrane aging" as an initial pathogenic factor that results in functional and structural alterations of membranes and, consequently, glucose hypometabolism and multiple pathophysiological cascades. PMID- 29177770 TI - Interventions to Improve Medicines Management for People with Dementia: A Systematic Review. AB - BACKGROUND: The importance of optimising medicines management for people with dementia has been emphasised through research and policy. However, evidence is currently lacking regarding how to achieve this in this patient population. OBJECTIVE: The aim was to assess the effectiveness of medicines management interventions for people with dementia living in their own home or a care home, with or without nursing care. METHODS: A systematic literature search was conducted in February 2016 across six electronic databases and three trial registries. Inclusion criteria were randomised controlled trials of medicines management (prescribing, dispensing, adherence, and/or review) interventions for people with dementia living in their own homes or care homes, with or without nursing. An assessment of quality was conducted for all studies, using the Cochrane tool for assessing the risk of bias. All outcomes were considered using a narrative approach. RESULTS: Overall, 1365 articles were identified, with three studies eligible for inclusion (n = 475 participants). The studies were heterogeneous both in terms of intervention components, setting, and outcomes used. Aspects of medicines management targeted included medication review, adherence, and administration. Improvements in psychotropic prescribing were observed; however, the interventions had limited effects on other outcomes such as wellbeing, falls and dementia severity. CONCLUSION: This review highlights the limited number of studies examining medicines management interventions for people with dementia. Of the work that has been conducted to date, emphasis has been placed on psychotropic drug use. Future research must target community-dwelling dementia patients and take a holistic approach to medicines management. PMID- 29177771 TI - Automatic gallbladder segmentation using combined 2D and 3D shape features to perform volumetric analysis in native and secretin-enhanced MRCP sequences. AB - OBJECTIVES: We aimed to develop the first fully automated 3D gallbladder segmentation approach to perform volumetric analysis in volume data of magnetic resonance (MR) cholangiopancreatography (MRCP) sequences. Volumetric gallbladder analysis is performed for non-contrast-enhanced and secretin-enhanced MRCP sequences. MATERIALS AND METHODS: Native and secretin-enhanced MRCP volume data were produced with a 1.5-T MR system. Images of coronal maximum intensity projections (MIP) are used to automatically compute 2D characteristic shape features of the gallbladder in the MIP images. A gallbladder shape space is generated to derive 3D gallbladder shape features, which are then combined with 2D gallbladder shape features in a support vector machine approach to detect gallbladder regions in MRCP volume data. A region-based level set approach is used for fine segmentation. Volumetric analysis is performed for both sequences to calculate gallbladder volume differences between both sequences. RESULTS: The approach presented achieves segmentation results with mean Dice coefficients of 0.917 in non-contrast-enhanced sequences and 0.904 in secretin-enhanced sequences. CONCLUSION: This is the first approach developed to detect and segment gallbladders in MR-based volume data automatically in both sequences. It can be used to perform gallbladder volume determination in epidemiological studies and to detect abnormal gallbladder volumes or shapes. The positive volume differences between both sequences may indicate the quantity of the pancreatobiliary reflux. PMID- 29177773 TI - A useful dressing for isolated digit injuries. AB - We propose a useful dressing for the post-operative care of isolated digit injuries using Coban Self-Adherent Wrap (3M). Coban is a latex-free self-adherent wrap, often used for the management of lower limb wounds and venous disease. The benefits of this dressing include a semi-rigid support to splint the digit yet it is lightweight and comfortable for the patient. The memory within the material also allows for expansion of the dressing in response to any swelling that may occur in the post-operative period, with subsequent retraction of the wrap once this subsides. We have achieved satisfactory results through the use of Coban, have wrapped over 100 digits and encountered no complications. PMID- 29177772 TI - An 8-channel Tx/Rx dipole array combined with 16 Rx loops for high-resolution functional cardiac imaging at 7 T. AB - OBJECTIVE: To demonstrate imaging performance for cardiac MR imaging at 7 T using a coil array of 8 transmit/receive dipole antennas and 16 receive loops. MATERIALS AND METHODS: An 8-channel dipole array was extended by adding 16 receive-only loops. Average power constraints were determined by electromagnetic simulations. Cine imaging was performed on eight healthy subjects. Geometrical factor (g-factor) maps were calculated to assess acceleration performance. Signal to-noise ratio (SNR)-scaled images were reconstructed for different combinations of receive channels, to demonstrate the SNR benefits of combining loops and dipoles. RESULTS: The overall image quality of the cardiac functional images was rated a 2.6 on a 4-point scale by two experienced radiologists. Imaging results at different acceleration factors demonstrate that acceleration factors up to 6 could be obtained while keeping the average g-factor below 1.27. SNR maps demonstrate that combining loops and dipoles provides a more than 50% enhancement of the SNR in the heart, compared to a situation where only loops or dipoles are used. CONCLUSION: This work demonstrates the performance of a combined loop/dipole array for cardiac imaging at 7 T. With this array, acceleration factors of 6 are possible without increasing the average g-factor in the heart beyond 1.27. Combining loops and dipoles in receive mode enhances the SNR compared to receiving with loops or dipoles only. PMID- 29177774 TI - Surgical treatment of periprosthetic femoral fractures: a retrospective study with functional and radiological outcomes from 2010 to 2016. AB - BACKGROUND: The treatment of periprosthetic femoral fractures is a great challenge for the orthopedic surgeon and requires a knowledge of bone fracture fixation as well as skills and experience in revision surgery. The aim of this retrospective study was to evaluate the functional and radiological outcomes of periprosthetic femoral fractures surgically treated in our department from 2010 to 2016. MATERIALS AND METHODS: This study involved 73 patients with a periprosthetic femoral fracture after total hip arthroplasty or hemiarthroplasty. Periprosthetic femoral fractures were classified using the Vancouver system. Functional outcomes were assessed using Harris hip score, Palmer Parker score, SF 36 score and ambulatory status. Radiological findings were classified using Beals and Tower's criteria. RESULTS: The mean age of patients was 79.6 years old. Local risks factors were identified in 67% of the patients, principally osteoporosis (63.0%), followed by osteolysis (26.0%) and loosening of the stem (8.2%). According to the Vancouver classification, there were 10 type A, 49 type B and 14 type C fractures. Of the type B fractures, 26 were B1, 17 were B2 and 6 were B3. Applying Beals and Tower's criteria, radiological results were excellent in 24 patients (32.9%), good in 35 (47.9%) and poor in 14 (19.2%). The mean Harris hip score post-operatively was 72.5. CONCLUSIONS: These kinds of fractures should be assessed individually and the optimal treatment plan should be made in accordance with the bone stock quality, stem stability, location of the fracture and patient expectations. PMID- 29177776 TI - Strength and microstructure characteristics of the recycled rubber tire-sand mixtures as lightweight backfill. AB - The disposal of scrap rubber tires has induced critical environmental issue worldwide due to the rapid increase in the number of vehicles. Recycled scrap tires as a construction material in civil engineering have significant environmental benefits from a waste management perspective. A systematic study that deals with strength and microstructure characteristics of the rubber-sand mixtures is initiated, and mechanical response of the mixtures is discussed in this investigation. Experiments were conducted to evaluate the effects of rubber fraction on the basic properties including mass density (rho), stress-strain characteristics, shear strength, and unconfined compression strength (q u) of the rubber-sand mixtures. Additionally, scanning electron microscopy (SEM) was carried out to reveal the microstructure characteristics of the mixtures with various rubber fractions. A discussion on the micromechanics of the mixtures also was conducted. This study demonstrates that the rho, friction angle, and q u decrease linearly with an increase in rubber fraction, whereas shear strain at peak increases. The stress-strain characteristics of the rubber-sand mixtures shift from brittle to ductile as the rubber fraction increase. These changes are attributed to remarkably lower stiffness and higher compressibility of the rubber particle compared with those of the conventional mineral aggregates. With an increase in the rubber fraction, the mechanical response of rubber-sand mixtures exhibits two types: sand-like material and rubber-like material. Rubber particle possesses the capacity to prevent the contacted sand particles from sliding at lower rubber fraction, whereas it transmits the applied loadings as the rubber fraction increased. This outcome reinforces the practicability of using recycled rubber tire-sand mixtures as a lightweight backfill in subbase/base applications.

AB - INTRODUCTION: The anatomic abnormalities in developmental dysplasia of hip (DDH) often make total hip replacement (THR) inevitable at a younger age. However, there is no universal gold standard technique of THR for high dislocated dysplastic hips. MATERIALS AND METHODS: Here we present the outcomes of midterm follow-up after THR in patients diagnosed with DDH Crowe type III and IV hospitalized in a tertiary center in Iran for whom placement of a cup in true acetabulum and selective transverse subtrochanteric osteotomy was performed. Pre- and postoperative Harris Hip Score, leg length discrepancy and postoperative complications were evaluated. RESULTS: A total of 48 patients with DDH Crowe type III and IV (uni- or bilateral which made 52 hips) were studied. Mean age of patients was 41 years with minimum follow-up ranging from 12 months to 3 years. Mean Harris Hip Score significantly improved from 41.70 preoperatively to 88.1 at last follow-up postoperatively. Leg length discrepancy of less than 2 cm was observed which was well tolerated using shoe lifts. Regarding postoperative complications, two patients had transient peroneal nerve palsy in early postoperative period which recovered within 2 months. No other major complication was encountered. CONCLUSION: THR in patients with DDH (Crowe III and IV) with a cup positioned in true acetabulum and transverse subtrochanteric osteotomy is a safe successful procedure. PMID- 29177777 TI - Comparative bioleaching of metals from pulverized and non-pulverized PCBs of cell phone charger: advantages of non-pulverized PCBs. AB - Sample inhomogeneity is a severe issue in printed circuit boards especially when we are comparing the bioleaching efficiency. To avoid the ambiguous results obtained due to inhomogeneity in PCBs, 12 similar cell phone chargers (of renowned company) having same make and batch number were collected from scrap market. PCBs obtained from them were used in present studies. Out of these 12, three PCBs were used separately for chemical analysis of PCBs with prior acid digestion in aqua regia. It was found that, 10.8, 68.0, and 710.9 mg/l of Zn, Pb, and Cu were present in it, respectively. Six PCBs were used for bioleaching experiment with two variations, pulverized and non-pulverized. Though the pulverized sample have shown better leaching than non-pulverized one, former has some disadvantages if overall recycling of e-waste (metallic and nonmetallic fraction) is to be addressed. At the end of leaching experiments, copper was recovered using a simple setup of electrodeposition and 92.85% recovery was attained. The acidophiles involved in bioleaching were identified by culture dependent and culture independent techniques such as DGGE and species specific primers in PCR. PMID- 29177778 TI - Development of an efficient viral aerosol collector for higher sampling flow rate. AB - Viral aerosol infection through cough generates large amounts of viral aerosol and can result in many adverse health effects such as influenza flu and severe acute respiratory syndrome (SARS). To characterize the coughed viral aerosol, the sampler needs to sample at higher flow rate and possess high physical collection efficiency as well as high viral preservation. However, most current inertia based high flow bioaerosol samplers are not suited for viral aerosol sampling since the viability will be lost doing the sampling process. Current condensation growth methods only have good physical collection efficiency and viral preservation at low flow rate (< 10 LPM). In this study, we developed a viral aerosol sampling system using a cooler and steam-jet aerosol collector (SJAC) for bioaerosol collection for the first time. The system is based on mixing condensation growth method and has high viral preservation at a higher flow rate (12.5 LPM). We control the inlet aerosol flow temperature and the SJAC mixing reservoir temperature to improve the physical collection efficiency and viability preservation of the viral aerosol. Results indicate that the physical collection efficiency is 70-99% for aerosol 30-100 nm when the aerosol flow and mixing reservoir temperature was 19 and 50 degrees C, respectively. In addition, the system was 7 and 22 times more efficient for viability preservation of MS2 bacteriophage than the commonly used All Glass Impinger 30 (AGI-30) and BioSampler(r), respectively. Finally, the system can be applied to sample at a lower concentration (105 PFU/m3), and results shows the system was 4.7 times more efficient for viability preservation than using AGI-30 alone. The developed viral collection system will improve our understanding of the characteristics of coughed aerosol and can be used for future evaluation of respiratory protective equipment and environmental sampling. PMID- 29177779 TI - Ethanolic extract of fenugreek seeds moderates dimethoate-induced pancreatic damage in male rats. AB - Dimethoate is a widely used organophosphate insecticide known to be toxic to the pancreas. The aim of this study is to detect the possible protective effects of the fenugreek seed ethanolic extract on the biochemical, histological, and ultra structural abnormalities induced by dimethoate chronic exposure in the pancreas of adult male rats. The study was conducted on 50 adult male albino rats that were divided equally into 5 groups: (group I) negative control, (group II) vehicle control group, (group III) fenugreek-treated group that was given 400 mg/kg ethanolic fenugreek seed extract once daily, (group IV) dimethoate group received 20 mg/kg/day dimethoate, and (group V) dimethoate- + fenugreek-treated group received a combination of dimethoate and fenugreek in the same previous doses. Dimethoate treatment caused a significant increase in serum glucose, amylase, and lipase levels and a significant decrease in serum insulin. A significant increase in lipid peroxidation and pro-fibrotic cytokine (TGF-beta1) together with a significant reduction of the antioxidant {reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD)} activities and the anti inflammatory (IL-4) in pancreatic tissues was also recorded. There was a histological and ultra-structural evidence of pancreatic acinar and islet cell injury. The recorded abnormalities were reversed in dimethoate+fenugreek treated group indicating that fenugreek ethanolic extract can serve as an antidote for dimethoate-induced pancreatic insult. PMID- 29177780 TI - Performance and biofilm characteristics of biotrickling filters for ethylbenzene removal in the presence of saponins. AB - Saponins were applied to enhance ethylbenzene removal in biotrickling filters (BTFs), and comparison experiments were carried out to evaluate the effects of saponins on ethylbenzene removal and biofilm characteristics at various saponin concentrations. Results showed that the optimum concentration of saponins was 40 mg/L and a maximum removal efficiency (RE) of ethylbenzene reached 84.3%. When the inlet ethylbenzene concentration increased, ranging from 750 to 2300 mg/m3, the RE decreased from 92.1 to 60.8% and from 69.4 to 44.2% for BTF1 and BTF2 in which saponin was and was not added, respectively. The corresponding RE declined from 91.1 to 40.8% and from 71.5 to 35.8% with a decreased empty bed residence time ranging from 45 to 7.5 s. Additionally, significant differences existed between both BTFs not only in the contents of polysaccharide and proteins but also in the surface charge of biofilms, and the ratio of protein to polysaccharide increased with the increase of saponin concentration, which indicated the presumable effect of saponins on liquid-biofilm transfer rates of ethylbenzene. Mechanisms for the enhanced removal of hydrophobic volatile organic compounds at the presence of surfactants were also discussed.

AB - This study was carried out to determine the concentrations of four heavy metals, cadmium (Cd), lead (Pb), copper (Cu), and cobalt (Co), and histopathological lesions in tissues of chickens reared in an industrial area of West Bengal, India. In particular, Mejhia Block was selected as a heavy metal-exposed area and Vatar Block (120 km away from industrially polluted areas) as a reference site. Samples were collected from the backyard chickens in these areas. Concentrations of heavy metals in soil, water, feedstuffs, tissues (liver, kidney, spleen, lung, and muscle), and droppings were greater (p < 0.05) in the polluted site than in the reference site. The greatest tissue concentrations of Cd and Pb were noted in the kidney, followed by the liver, lung, spleen, and muscle, whereas Cu and Co concentrations accumulated in these tissues resulted in the following: liver > kidney > lung > spleen > muscle. Heavy metal concentrations were greater in older chickens (> 1 year) than in young chickens (< 1 year). Packed cell volume, total erythrocyte counts, hemoglobin, total protein, and total leucocyte counts were significantly (p < 0.01) lower in the blood picture of chickens in the exposed area. Different serum enzymes and biochemical profiles were altered due to heavy metal exposure. Histological changes revealed necrotic lesions and tubulitis in the kidney, degeneration and necrosis in liver parenchyma, and periarteriolitis, peribronchiolitis, and presence of hemosiderin pigment in the lung of chickens in the exposed site. Results indicated that backyard chickens in heavy metal-exposed site may show pathological lesions in different tissues due to accumulation of heavy metals, and thus, the consumption of chicken meat from the industrially exposed site may pose a potential health risk to local residents of polluted sites.

AB - The contamination level of 12 antibiotics in 8 species of fish and shrimp from the Dongting Lake, China, was firstly studied. In total, the concentrations of antibiotics in fish and shrimp were lower, which were far lower than the maximum residue limits. The most abundant compound was enrofloxacin followed by sulfadiazine, sulfamethoxazole, sarafloxacin, and sulfadimidine with the highest content from 0.37 to 1.06 ng g-1. The concentrations in Silurus asotus, Cyprinus carpio, and Palinuridae were higher. Concentrations in fish and shrimp from different water layers showed spatial difference, with the order of benthos and middle-lower species > middle-upper species. In addition, the antibiotic content could be affected by the diet, which showed the concentration level of antibiotics decreased in the order of carnivorous > omnivorous > phytophagous species. Human health risk assessment based on potential fish consumption indicates that main antibiotic risk factors were enrofloxacin and sarafloxacin, and main risk species were Silurus asotus and Palinuridae. The daily risk quotient of these antibiotics to rural residents was lower than townsmen. This study is the first report of antibiotic content in fish and shrimp from the Dongting Lake, which could enrich the research of emerging pollutants in aquatic products.

AB - Copper in drinking water causes a significant environmental problem. Composite material based on alginate hydrogel has been gaining attention in the field of Cu(II) adsorption. However, alginate-based hydrogel exhibits poor mechanical property and relative low adsorption capacity which limit their application. The present study is devoted to the modification of chitosan/calcium alginate/Fe3O4 (CAF) hydrogel microsphere by NaOH solution for enhancement of Cu(II) adsorption. Results reveal that modification of CAF via NaOH solution significantly improves the mechanical strength and Cu2+ adsorption capacity of pristine materials. FTIR and XRD analysis confirms that CAF and newly prepared materials (NACAF) are successfully prepared. SEM and EDX are employed to analyze the surface morphology and elemental composition, respectively, both before and after their loading with Cu2+. XPS study demonstrates adsorption mechanism is based on chelation and ion exchange. Compressive stress-strain curves demonstrate NACAF has better mechanical performance than CAF. The adsorption kinetics of the two adsorbents follow a pseudo-second-order model. The equilibrium data were best described by Langmuir isotherm model, and the estimated maximum equilibrium sorption capacity, q m,is 261.31 mg/g for the NACAF, which is larger than that of CAF (145.39 mg/g). Hence, NACAF shows excellent mechanical strength and high sorption capacity for Cu2+. It has great potential for Cu(II) removal in aqueous solutions.

AB - This study evaluated the effects of a hyperaccumulator plant (Arabidopsis halleri), containing surplus of cadmium (Cd) and zinc (Zn) and being an admixture to the rat feed, on concentrations of copper (Cu), iron (Fe), and manganese (Mn) in the tissues of experimental rats infected/uninfected with the tapeworm (Hymenolepis diminuta). Male Wistar rats were divided into three groups (00, P0, and PT); the P0 and PT animals were fed a standard mixture for rats (ST-1) supplemented with the plant A. halleri at a weekly Zn and Cd dosage of 123 and 1 mg, respectively. Moreover, rats from the group PT were infected with the tapeworm. The group 00 served as control animals fed only ST-1 having no tapeworm infection. Rats were euthanized after 6 weeks, and Cu, Fe, and Mn levels were determined in rat and tapeworm tissues. The results indicated that both the consumption of hyperaccumulator plant and/or presence of tapeworms did have significant effect on Cu, Fe, and Mn concentrations in the host tissues. Concentrations of all the elements were higher in the rat liver and partially kidneys than in the tapeworms, and the concentrations of Cu, Fe, and Mn were affected by the consumption of Cd/Zn hyperaccumulator plants. Particularly, Fe concentrations in all rat tissues were significantly increased by consumption of A. halleri while decreased by the presence of tapeworms. Overall, the consumption of a Cd/Zn hyperaccumulator plant and tapeworm infection cause an imbalance in Cu, Fe, and Mn concentrations in the tissues of a consumer (experimental rats). PMID- 29177786 TI - Nematicidal potential and specific enzyme activity enhancement potential of neem (Azadirachta indica A. Juss.) aerial parts. AB - Nematodes are considered as major plant parasites damaging most of the crops, and neem plant exhibits potential nematicidal and insecticidal properties. This study aimed to check nemato-toxic potential of neem (Azadirachta indica) plant using in vitro and in-planta trials against Meloidogyne incognita. The findings suggested that the neem extracts were lethal to second-stage juvenile (J2) and egg hatching with simultaneous enhancement in treated tomato plant growth. The egg numbers of M. incognita found less sensitive to the aqueous and alcoholic extracts than those of J2 as per LC50 values. Complete mortality of J2s was recorded at 40, 60, and 80% of neem standard extract (SE) dilutions and for undiluted SE of neem. The undiluted SE extract showed 100% inhibition of egg production. The highest reductions in the number of galls/root system, J2 population, and egg production were observed with 80, 85, and 82% SE as compared control (untreated distilled water). The maximum 250% growth increment was observed in the length of tomato roots supplemented with neem extracts. Resistance-related enzyme [phenylalanine ammonia lyase (PAL), polyphenol oxidase (PPO), and peroxidase (POX)] activities in tomato plant have been increased significantly by supplementation with neem extracts. It appears that the aerial parts of neem (A. indica) extracts showed significant and sustainable eco-friendly nemato-toxic potential towards M. incognita growth inhibition and eradication using alcoholic extracts compared to aqueous. From this study, it was concluded that the neem aerial parts were useful for the control of M. incognita and could be a possible replacement for synthetic nematicides in crop protection with utilization in enhancement of specific enzyme activity in tomato plants. PMID- 29177785 TI - Elemental composition of PM2.5 in the urban environment of San Juan, Argentina. AB - This study contributes to the current knowledge about air pollution in the province of San Juan, Argentina. Sampling was carried out to measure the fine particulate matter in the atmosphere (PM2.5) of the city of San Juan. PM2.5 was collected continuously during the winter and spring seasons of 2014 and 2015, and the concentrations of 14 elements (Pb, Ca, K, Cd, Ni, Cr, Mn, V, Cu, Ti, Ba, Co, Sr, and Fe) were determined in PM2.5 filters using the technique of X-ray fluorescence by synchrotron radiation (SR-XRF). The results revealed that PM2.5 presented annual and seasonal variations, showing a higher concentration during the winter seasons. In addition, for the elements quantified in the filters, a multivariate analysis (Positive Matrix Factorization) was performed to identify the main sources of emission of these elements in the study area, with a series of components being obtained that corresponded to their compositions, which were assigned physical meanings. The first factor, which was the most important in contribution of the sum of the measured elements (45%), was determined mainly by the elements K, Ti, V, Mn, and Fe, which came predominantly from soil particles. The second factor contributed 30% to the measured species in PM2.5, with higher Ba and Zn content perhaps being related to emissions from vehicular traffic. Finally, the third factor, in which Pb, Cr, and Ca predominated, may be an indicator of industrial activity and contributed 25% of the sum of the measured elements of PM2.5. The results of this study provide the first PM composition database in the province, and this can now be used in the development of mitigation and prevention programs. PMID- 29177787 TI - Trace metal accumulation by Ranunculus sceleratus: implications for phytostabilization. AB - This study investigated the growth response of Ranunculus sceleratus to pollution and its capacity to accumulate trace metals for its use as a phytoremediator in Lake Maruit, Egypt. Three basins (main basin, fish farm, and southwestern basin) representing the natural distribution of the plant as well as the pollution loads in the lake, were chosen for collecting plant and sediment samples. In each basin ten quadrats (0.5 m * 0.5 m), distributed equally along two sites, were selected for measuring growth parameters, nutrients, and trace metal concentration. The highest biomass of the shoot and root (610 and 236 g m-2) was recorded in the main basin and fish farm, respectively. R. sceleratus accumulated high concentrations of Cu and Pb (27.7 and 9.9 mg kg-1), while toxic concentration of Mn (2508.0 mg kg-1) in their roots compared to shoots. The bioaccumulation factor (BF) for the investigated metals was greater than one, and in the decreasing order: Ni (27.1) > Zn (20.0) > Cd (16.4) > Cu (7.7) > Mn (3.9) > Pb (3.6). The translocation factor of all analyzed trace metals was less than one. The ability of R. sceleratus to accumulate Mn, Ni, Cu, and Pb in its roots indicates the potential use of this species for phytostabilization of these metals (mainly Mn) in contaminated water bodies.

PMID- 29177789 TI - Carotid near-occlusion frequently has high peak systolic velocity on Doppler ultrasound. AB - PURPOSE: Carotid near-occlusion is a tight atherosclerotic stenosis of the internal carotid artery (ICA) resulting in decrease in diameter of the vessel lumen distal to the stenosis. Near-occlusions can be classified as with or without full collapse, and may have high peak systolic velocity (PSV) across the stenosis, mimicking conventional > 50% carotid artery stenosis. We aimed to determine how frequently near-occlusions have high PSV in the stenosis and determine how accurately carotid Doppler ultrasound can distinguish high-velocity near-occlusion from conventional stenosis. METHODS: Included patients had near occlusion or conventional stenosis with carotid ultrasound and CT angiogram (CTA) performed within 30 days of each other. CTA examinations were analyzed by two blinded expert readers. Velocities in the internal and common carotid arteries were recorded. Mean velocity, pulsatility index, and ratios were calculated, giving 12 Doppler parameters for analysis. RESULTS: Of 136 patients, 82 had conventional stenosis and 54 had near-occlusion on CTA. Of near-occlusions, 40 (74%) had high PSV (>= 125 cm/s) across the stenosis. Ten Doppler parameters significantly differed between conventional stenosis and high-velocity near occlusion groups. However, no parameter was highly sensitive and specific to separate the groups. CONCLUSION: Near-occlusions frequently have high PSV across the stenosis, particularly those without full collapse. Carotid Doppler ultrasound does not seem able to distinguish conventional stenosis from high velocity near-occlusion. These findings question the use of ultrasound alone for preoperative imaging evaluation. PMID- 29177790 TI - Computational Intelligence for Medical Imaging Simulations. AB - This paper describes how to simulate medical imaging by computational intelligence to explore areas that cannot be easily achieved by traditional ways, including genes and proteins simulations related to cancer development and immunity. This paper has presented simulations and virtual inspections of BIRC3, BIRC6, CCL4, KLKB1 and CYP2A6 with their outputs and explanations, as well as brain segment intensity due to dancing. Our proposed MapReduce framework with the fusion algorithm can simulate medical imaging. The concept is very similar to the digital surface theories to simulate how biological units can get together to form bigger units, until the formation of the entire unit of biological subject. The M-Fusion and M-Update function by the fusion algorithm can achieve a good performance evaluation which can process and visualize up to 40 GB of data within 600 s. We conclude that computational intelligence can provide effective and efficient healthcare research offered by simulations and visualization. PMID- 29177791 TI - SR 11302, an AP-1 Inhibitor, Reduces Metastatic Lesion Formation in Ex Vivo 4D Lung Cancer Model. AB - Activator protein (AP) -1 is a transcription factor, plays important role in cell differentiation, proliferation and apoptosis. Analysis of tumor cells grown on ex vivo 4D lung cancer model shows increase in components of AP-1, c-Fos and c-Jun in circulating tumor cells (CTC) compared to primary tumor. Our aim was to determine whether the AP-1 inhibitor SR11302 reduces metastatic lesion formation in the 4D model. Human lung cancer cell lines A549, H1299, and H460 were grown in the 4D model and treated with SR11302 (1 MUM). We compared the number of cells in the metastatic site upon SR11302 treatment and number of viable CTCs isolated from the 4D model with parental cells treated/untreated with SR11302 on a petri dish. There were significantly fewer tumor cells per high-power field on metastatic site in 4D model seeded with H460 (p = 0.009), A549 (p = 0.01), or H1299 (p = 0.02) cells treated with SR11302. Furthermore, the CTCs from SR11302 treated 4D models, seeded with H460 (p = 0.04), A549 (p = 0.008), or H1299 (p = 0.01) cells had significantly fewer viable tumor cells after 4 days in culture than the respective untreated control. However, the SR11302 had no impact on the viability of parental H460 (p = 0.87), A549 (p = 0.93), or H1299 (p = 0.25) cells grown on a petri dish (2D). SR11302 reduces metastatic lesion formation in the ex vivo 4D lung cancer model due to the presence of an independent yet common pathway among three cell lines. The ex vivo 4D model may provide a tool to better understand the complex process of metastasis. PMID- 29177792 TI - New 8,12;8,20-diepoxy-8,14-secopregnane hexa- and hepta-glycosides from the roots of Asclepias tuberosa. AB - Previously, phytochemical investigation of the roots of Asclepias tuberosa (Asclepiadaceae) led to the isolation of some 8,12;8,20-diepoxy-8,14-secopregnane tri-, tetra-, and penta-glycosides. An additional eight new minor 8,12;8,20 diepoxy-8,14-secopregnane glycosides were afforded in the recent investigation of this plant. These glycosides consisted of six or seven 2,6-dideoxy-hexopyranoses together with the aglycone, tuberogenin. The structures of each of these compounds were established using NMR, mass spectroscopic analysis and chemical evidence. As 8,12;8,20-diepoxy-8,14-secopregnane-type glycosides were observed only in A. tuberosa, these compounds were considered to be characteristic phytochemicals of this plant.

AB - The occurrence of thymoma in myotonic dystrophy type 1 (DM1) has been occasionally reported, and an increased risk of tumors has been observed. We performed imaging of the thymus in 22 patients carrying DMPK expansion. Clinical examination and routine instrumental exams were performed at the same time. We observed no thymic abnormalities in 13 subjects, thymic hyperplasia in eight patients, and an invasive thymoma in one case. Subjects with thymic abnormalities did not show peculiarities as regards clinical and electrophysiological features. We observed thymoma in one patient with an expansion in the higher range. Abnormalities of the thymus including hyperplasia and thymoma can be present in DM1, but do not seem to play a major role in DM1 pathogenesis. Further studies are needed to understand if some RNA splicing factors involved in DM1 and influenced by CTG expansion size could have a role in thymocytes proliferation. PMID- 29177795 TI - Myocardial injury after endovascular revascularization in critical limb ischemia predicts 1-year mortality: a prospective observational cohort study. AB - BACKGROUND: Patients with critical limb ischemia (CLI) are at increased risk of cardiovascular complications and mortality. To determine (1) incidence of myocardial injury following endovascular revascularization, and (2) relationship between myocardial injury with 1-year mortality and major adverse cardiovascular events (MACE; i.e., composite of myocardial infarction, stroke, and death). METHODS AND RESULTS: Single-center, prospective cohort study of CLI patients >= 45 years of age, who underwent endovascular revascularization with overnight hospitalization. High-sensitive troponins T (hsTnTs) were measured on admission, 3-6 h after endovascular revascularization and the subsequent morning. Myocardial injury after endovascular revascularization was defined as an hsTnT >= 14 ng/L with a relative increase >= 30% from the baseline value. We also evaluated other myocardial injury hsTnT thresholds (i.e., >= 30, >= 40, >= 60, and >= 80 ng/L). 239 consecutive patients (56% male, mean age 71.5 +/- 10.1 years) were included; one patient was lost to follow-up. At 1 year, there were 34 deaths (14.2%), and 48 MACE (20.5%). Myocardial injury with the hsTnT threshold of 14 ng/L and relative increase by >= 30% from the baseline level occurred in 61 patients (25.5%). Myocardial injury was independently associated with 1-year mortality ([aHR], 2.44; 95% CI 1.18-5.06, for hsTnT >= 14 ng/L to aHR, 3.34; 95% CI 1.29 8.65 for hsTnT >= 80 ng/L). Myocardial injury was also independently associated with 1-year MACE ([AOR] 2.89; 95% CI 1.41-5.92 for hsTnT >= 14 ng/L to AOR, 6.69; 95% CI 2.17-20.68 for hsTnT >= 80 ng/L). 85.2% patients who had myocardial injury did not have ischemic clinical symptoms or electrocardiography changes. In sensitive analysis with exclusion of symptomatic patients that developed myocardial injury for the hsTnT >= 14 ng/L threshold, both the 1-year mortality (aHR: 2.19; CI 1.02-4.68; p = 0.04), and 1-year MACE (OR 2.25; CI 1.06-4.77; p = 0.036) remained significant. CONCLUSIONS: Myocardial injury is common following endovascular revascularization for CLI and associated with the risk of 1-year mortality and MACE.

AB - Mesenchymal stem cells (MSCs) are promising resource for the therapy of inflammatory bowel diseases (IBDs) on the grounds of their differentiation capabilities and immuno-modulatory characteristics. Results of clinical studies indicate that local application of MSCs is a secure and beneficial approach for the treatment of perianal fistulas while systemic application of MSCs leads to the attenuation or aggravation of IBDs. Herein, we emphasized molecular mechanisms and approaches that should improve efficacy of MSC-based therapy of IBDs. PMID- 29177797 TI - A Systematic Review Comparing the Acceptability, Validity and Concordance of Discrete Choice Experiments and Best-Worst Scaling for Eliciting Preferences in Healthcare. AB - OBJECTIVE: The aim of this study was to compare the acceptability, validity and concordance of discrete choice experiment (DCE) and best-worst scaling (BWS) stated preference approaches in health. METHODS: A systematic search of EMBASE, Medline, AMED, PubMed, CINAHL, Cochrane Library and EconLit databases was undertaken in October to December 2016 without date restriction. Studies were included if they were published in English, presented empirical data related to the administration or findings of traditional format DCE and object-, profile- or multiprofile-case BWS, and were related to health. Study quality was assessed using the PREFS checklist. RESULTS: Fourteen articles describing 12 studies were included, comparing DCE with profile-case BWS (9 studies), DCE and multiprofile case BWS (1 study), and profile- and multiprofile-case BWS (2 studies). Although limited and inconsistent, the balance of evidence suggests that preferences derived from DCE and profile-case BWS may not be concordant, regardless of the decision context. Preferences estimated from DCE and multiprofile-case BWS may be concordant (single study). Profile- and multiprofile-case BWS appear more statistically efficient than DCE, but no evidence is available to suggest they have a greater response efficiency. Little evidence suggests superior validity for one format over another. Participant acceptability may favour DCE, which had a lower self-reported task difficulty and was preferred over profile-case BWS in a priority setting but not necessarily in other decision contexts. CONCLUSION: DCE and profile-case BWS may be of equal validity but give different preference estimates regardless of the health context; thus, they may be measuring different constructs. Therefore, choice between methods is likely to be based on normative considerations related to coherence with theoretical frameworks and on pragmatic considerations related to ease of data collection. PMID- 29177798 TI - Predicting the risk of cucurbit downy mildew in the eastern United States using an integrated aerobiological model. AB - Cucurbit downy mildew caused by the obligate oomycete, Pseudoperonospora cubensis, is considered one of the most economically important diseases of cucurbits worldwide. In the continental United States, the pathogen overwinters in southern Florida and along the coast of the Gulf of Mexico. Outbreaks of the disease in northern states occur annually via long-distance aerial transport of sporangia from infected source fields. An integrated aerobiological modeling system has been developed to predict the risk of disease occurrence and to facilitate timely use of fungicides for disease management. The forecasting system, which combines information on known inoculum sources, long-distance atmospheric spore transport and spore deposition modules, was tested to determine its accuracy in predicting risk of disease outbreak. Rainwater samples at disease monitoring sites in Alabama, Georgia, Louisiana, New York, North Carolina, Ohio, Pennsylvania and South Carolina were collected weekly from planting to the first appearance of symptoms at the field sites during the 2013, 2014, and 2015 growing seasons. A conventional PCR assay with primers specific to P. cubensis was used to detect the presence of sporangia in rain water samples. Disease forecasts were monitored and recorded for each site after each rain event until initial disease symptoms appeared. The pathogen was detected in 38 of the 187 rainwater samples collected during the study period. The forecasting system correctly predicted the risk of disease outbreak based on the presence of sporangia or appearance of initial disease symptoms with an overall accuracy rate of 66 and 75%, respectively. In addition, the probability that the forecasting system correctly classified the presence or absence of disease was >= 73%. The true skill statistic calculated based on the appearance of disease symptoms in cucurbit field plantings ranged from 0.42 to 0.58, indicating that the disease forecasting system had an acceptable to good performance in predicting the risk of cucurbit downy mildew outbreak in the eastern United States.

AB - Caregivers of children in alternative care face a complex range of challenges that can result in placement disruption and poor long-term outcomes. Interventions designed to help carers meet these challenges report positive outcomes. Nevertheless, several reviewers have reported these positive results may be mitigated by limitations in trial methodology. This review aims to systematically review these methodological challenges and limitations, to provide an analysis of the current state of the evidence base for these interventions. A systematic review was conducted into the methods used to evaluate the effectiveness of psychosocial interventions for foster and kinship carers. Limitations relating to internal validity, external validity and clinical heterogeneity were identified and synthesised. Seventeen studies met inclusion criteria. The quality of methods used in the included studies is mixed, with high and unknown levels of bias in the majority of trials. Heterogeneity in participant characteristics, intervention aims and outcome measures across interventions reflect the diversity of carer and child needs and make it difficult to generalise results or compare and synthesise the efficacy of different interventions. These factors limit the application of trial results to evidence-based clinical practice. The diverse and complex needs of this population present significant challenges to robustly evaluating interventions for foster/kinship families. Participant needs, theoretical approaches, intervention aims and outcome measures need to be better coordinated, both within trials and across the field. Exploratory research should be used to generate focussed and concrete hypotheses that can be robustly tested in high-quality randomised controlled trials.

AB - The basic goal of this study was to synthesize zinc oxide nanoparticles using the Chelidonium majus extract and asses their cytotoxic and antimicrobial properties. The synthesized ZnO NPs were characterized by UV-Vis, Scanning Electron Microscopy (SEM) with EDS profile, Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM). The aforementioned methods confirmed that the size of synthesized ZnO nanoparticles was at the range of 10 nm. The antimicrobial activity of ZnO nanoparticles synthesized using the Ch. majus extract was tested against standard strains of bacteria (Staphylococcus aureus NCTC 4163, Pseudomonas aeruginosa NCTC 6749, Escherichia coli ATCC 25922), yeast (Candida albicans ATCC 10231), filamentous fungi (molds: Aspergillus niger ATCC 16404, dermatophytes: Trichophyton rubrum ATCC 28188), clinical strains of bacteria (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus) and yeast (Candida albicans). The study showed that zinc oxide nanoparticles were excellent antimicrobial agents. What is more, biologically synthesized ZnO nanoparticles demonstrate high efficiency in treatment of human non-small cell lung cancer A549.

AB - OBJECTIVE: To determine if intra-articular signal changes at the sacroiliac joint space on MRI have added diagnostic value for spondyloarthritis, when compared to bone marrow edema (BME). MATERIALS AND METHODS: A retrospective study was performed on the MRIs of sacroiliac joints of 363 patients, aged 16-45 years, clinically suspected of sacroiliitis. BME of the sacroiliac joints was correlated to intra-articular sacroiliac joint MR signal changes: high T1 signal, fluid signal, ankylosis and vacuum phenomenon (VP). These MRI findings were correlated with final clinical diagnosis. Sensitivity (SN), specificity (SP), likelihood ratios (LR), predictive values and post-test probabilities were calculated. RESULTS: BME had SN of 68.9%, SP of 74.0% and LR+ of 2.6 for diagnosis of spondyloarthritis. BME in absence of intra-articular signal changes had a lower SN and LR+ for spondyloarthritis (SN = 20.5%, LR+ 1.4). Concomitant BME and high T1 signal (SP = 97.2%, LR + = 10.5), BME and fluid signal (SP = 98.6%, LR + = 10.3) or BME and ankylosis (SP = 100%) had higher SP and LR+ for spondyloarthritis. Concomitant BME and VP had low LR+ for spondyloarthritis (SP = 91%, LR + =0.9). When BME was absent, intra-articular signal changes were less prevalent, but remained highly specific for spondyloarthritis. CONCLUSION: Our results suggest that both periarticular and intra-articular MR signal of the sacroiliac joint should be examined to determine whether an MRI is 'positive' or 'not positive' for sacroiliitis associated with spondyloarthritis. PMID- 29177805 TI - Inhibitory Effects of Honokiol on the Voltage-Gated Potassium Channels in Freshly Isolated Mouse Dorsal Root Ganglion Neurons. AB - Voltage-gated potassium (KV) currents, subdivided into rapidly inactivating A type currents (I A) and slowly inactivating delayed rectifier currents (I K), play a fundamental role in modulating pain by controlling neuronal excitability. The effects of Honokiol (Hon), a natural biphenolic compound derived from Magnolia officinalis, on KV currents were investigated in freshly isolated mouse dorsal root ganglion neurons using the whole-cell patch clamp technique. Results showed that Hon inhibited I A and I K in concentration-dependent manner. The IC50 values for block of I A and I K were 30.5 and 25.7 uM, respectively. Hon (30 uM) shifted the steady-state activation curves of I A and I K to positive potentials by 17.6 and 16.7 mV, whereas inactivation and recovery from the inactivated state of I A were unaffected. These results suggest that Hon preferentially interacts with the active states of the I A and I K channels, and has no effect on the resting state and inactivated state of the I A channel. Blockade on K+ channels by Hon may contribute to its antinociceptive effect, especially anti-inflammatory pain. PMID- 29177806 TI - The long-term survival in primary retroperitoneal mucinous cystadenocarcinoma: a case report. AB - BACKGROUND: Primary retroperitoneal mucinous cystadenocarcinoma (PRMC) is extremely rare, and its biological behavior, pathogenesis, optimum treatments, and prognosis remain to be elucidated. We herein report a case of PRMC with an 80 month follow-up. CASE PRESENTATION: A 29-year-old woman was diagnosed with unknown retroperitoneal tumor with benign right ovarian cyst and uterine fibroids, and she underwent laparotomy. The tumor was completely resected with a subsequent histopathological diagnosis of primary retroperitoneal mucinous cystadenocarcinoma (PRMC). Eighty months after surgery, she remains recurrence free. CONCLUSION: PRMC is an extremely rare tumor. Only around 60 cases have so far been published in the literature. The preoperative diagnosis of PRMC is difficult, and a definitive diagnosis can usually only be made based on the findings of histopathological examinations after surgery. Presently, only radical resection is useful for both diagnostic and therapeutic purposes. The optimal long-term management after surgery is still not well established. Further studies on PRMC are therefore needed to elucidate the etiology and establish effective treatments. PMID- 29177807 TI - Collagen degradation as a possibility to determine the post-mortem interval (PMI) of animal bones: a validation study referring to an original study of Boaks et al. (2014). AB - Estimation of the post-mortem interval (PMI) of unknown skeletal remains is a common forensic task. Boaks and colleagues demonstrated a new method for PMI estimation in showing a reduction of the collagen to non-collagen content (Co/NCo ratio) in porcine bones after a PMI of 12 months using the Sirius Red/Fast Green Collagen Staining Kit from Chondrex in 2014 (Boaks et al. Forensic Sci Int 240: 104-110, 2014). The aim of our study was to reproduce this method and to investigate if the method could be used for forensic issues. Sixteen fresh porcine bones were placed in prepared boxes where they were treated regularly with distilled water or with water from hay infusions. For determining the Co/NCo ratio, we used the Sirius Red/Fast Green Collagen Staining Kit from Chondrex, which stains collagenous (Co) proteins red and non-collagenous (NCo) proteins green Chondrex Inc. (2008). After a PMI of 1-3 months, an analysis of porcine bone thin sections was performed on the one hand with spectrophotometry, on the other hand with stereomicroscopy. Using spectrophotometry, we go low and partially negative Co/NCo ratios which were up to 100-fold lower than the results we expected to get. The data we got by stereomicroscopy and calculating the Co/NCo ratio from extracting the red and green content with the software MATLAB and so calculating the Co/NCo ratio showed a correlation between PMI and the Co/NCo ratio in the porcine bone samples. Regular addition of distilled water or water from a hay infusion did not produce any significant differences so that an increased presence of microorganisms had obviously no influence on collagen degradation.

Historical aspects and possible pathomechanisms. AB - The incidence of SIDS decreased during the previous 25 years significantly. This is mainly due to epidemiological research identifying important risk factors such as prone sleeping position and subsequent campaigns to reduce this risk factor.Originally, the prone sleeping position for babies had been strongly recommended in the sixties and seventies despite previous publications pointed to the associated risk. Worldwide, many infants died of SIDS whose deaths could have been avoided. Today, the recommendation that infants should sleep in supine position has been scientifically verified. In supine sleeping position, pathophysiological mechanisms can be avoided which may lead to hypoxia and death in prone position. Such mechanisms could be occlusion of airways (in particularly associated with face-down position), elevated diaphragm, positional cerebral hypoxia caused by constriction of arteries, rebreathing CO2, and overheating.Irrespective of the specific pathomechanism leading to death in individual cases, it has been established that the prone position is the most important risk factor for SIDS and therefore should be incorporated in the definition of the term SIDS. PMID- 29177809 TI - Parallel in vivo and in vitro transcriptomics analysis reveals calcium and zinc signalling in the brain as sensitive targets of HBCD neurotoxicity. AB - Hexabromocyclododecane (HBCD) is a brominated flame retardant (BFR) that accumulates in humans and affects the nervous system. To elucidate the mechanisms of HBCD neurotoxicity, we used transcriptomic profiling in brains of female mice exposed through their diet to HBCD (199 mg/kg body weight per day) for 28 days and compared with those of neuronal N2A and NSC-19 cell lines exposed to 1 or 2 uM HBCD. Similar pathways and functions were affected both in vivo and in vitro, including Ca2+ and Zn2+ signalling, glutamatergic neuron activity, apoptosis, and oxidative stress. Release of cytosolic free Zn2+ by HBCD was confirmed in N2A cells. This Zn2+ release was partially quenched by the antioxidant N-acetyl cysteine indicating that, in accordance with transcriptomic analysis, free radical formation is involved in HBCD toxicity. To investigate the effects of HBCD in excitable cells, we isolated mouse hippocampal neurons and monitored Ca2+ signalling triggered by extracellular glutamate or zinc, which are co-released pre-synaptically to trigger postsynaptic signalling. In control cells application of zinc or glutamate triggered a rapid rise of intracellular [Ca2+]. Treatment of the cultures with 1 uM of HBCD was sufficient to reduce the glutamate-dependent Ca2+ signal by 50%. The effect of HBCD on zinc-dependent Ca2+ signalling was even more pronounced, resulting in the reduction of the Ca2+ signal with 86% inhibition at 1 uM HBCD. Our results show that low concentrations of HBCD affect neural signalling in mouse brain acting through dysregulation of Ca2+ and Zn2+ homeostasis.

AB - The aim of this article is to provide an in depth review of the rare genetic and syndromic forms of childhood obesity. The authors demonstrate the complexity and inter-relationships of the leptin-melanocortin signaling pathway and its central nervous system and systemic effects.

They outline specific genetic testing and treatment options available for these conditions. PMID- 29177812 TI - Anaerobic degradation of 1-methylnaphthalene by a member of the Thermoanaerobacteraceae contained in an iron-reducing enrichment culture. AB - An anaerobic culture (1MN) was enriched with 1-methylnaphthalene as sole source of carbon and electrons and Fe(OH)3 as electron acceptor. 1-Naphthoic acid was produced as a metabolite during growth with 1-methylnaphthalene while 2-naphthoic acid was detected with naphthalene and 2-methylnaphthalene. This indicates that the degradation pathway of 1-methylnaphthalene might differ from naphthalene and 2-methylnaphthalene degradation in sulfate reducers. Terminal restriction fragment length polymorphism and pyrosequencing revealed that the culture is mainly composed of two bacteria related to uncultured Gram-positive Thermoanaerobacteraceae and uncultured gram-negative Desulfobulbaceae. Stable isotope probing showed that a 13C-carbon label from 13C10-naphthalene as growth substrate was mostly incorporated by the Thermoanaerobacteraceae. The presence of putative genes involved in naphthalene degradation in the genome of this organism was confirmed via assembly-based metagenomics and supports that it is the naphthalene-degrading bacterium in the culture. Thermoanaerobacteraceae have previously been detected in oil sludge under thermophilic conditions, but have not been shown to degrade hydrocarbons so far. The second member of the community belongs to the Desulfobulbaceae and has high sequence similarity to uncultured bacteria from contaminated sites including recently proposed groundwater cable bacteria. We suggest that the gram-positive Thermoanaerobacteraceae degrade polycyclic aromatic hydrocarbons while the Desulfobacterales are mainly responsible for Fe(III) reduction. PMID- 29177813 TI - Micro-CT evaluation of voids using two root filling techniques in the placement of MTA in mesial root canals of Vertucci type II configuration. AB - OBJECTIVE: The present study aims to compare two mineral trioxide aggregate (MTA) placement techniques, manual compaction and ultrasonic activation of manually compacted MTA, with warm vertical compaction (WVC) for orthograde obturation of mesial root canals of mandibular first molars showing Vertucci type II root canal configuration. MATERIALS AND METHODS: Thirty roots were selected according to their micro-CT scanned images. Root canals were chemomechanically prepared using Reciproc R25 and NaOCl using EndoVac. The specimens were divided into three groups according to the root canal filling technique, as manual compaction of MTA, ultrasonic activation of manually compacted MTA and WVC using gutta-percha and AH Plus (Denstply Sirona, Ballaigues, Switzerland). Percentages of voids located in apical 3 mm and remaining coronal half until the level where separate root canals re-join within filling were calculated. Data were analyzed using the Kruskal-Wallis and Dunn's tests, and significance was set at 5%. RESULTS: No significant difference was found among the filling techniques regarding the percentage volume of voids at apical 3 mm (P > 0.05). At the coronal half of the isthmus, WVC produced significantly less percentage volume of voids than manual compaction of MTA (P < 0.05) and similar to ultrasonic activation group did (P > 0.05). There was no significant difference between two MTA placement techniques at the coronal half of the isthmus (P > 0.05). CONCLUSIONS: No filling technique produced void-free fillings. The percentage of void volume was similar among groups at apical 3 mm but was different at the coronal half of the isthmus. CLINICAL RELEVANCE: Warm vertical compaction and ultrasonically activated MTA fillings revealed similar quality at the isthmus area, which was superior to manually compacted MTA. PMID- 29177814 TI - Orofacial manifestations in outpatients with anorexia nervosa and bulimia nervosa focusing on the vomiting behavior. AB - OBJECTIVE: This case-control study aims to evaluate the oral health status and orofacial problems in a group of outpatients with eating disorders (ED)-either anorexia nervosa (AN) or bulimia nervosa (BN)-further focusing on the influence of vomit. MATERIALS AND METHODS: Fifty-five women outpatients with AN or BN diagnosis were invited to participate, of which 33 agreed. ED outpatients and matched controls were submitted to a questionnaire and clinical oral examination. RESULTS: Multivariate analysis identified a significantly higher incidence of teeth-related complications (i.e., tooth decay, dental erosion, and self-reported dentin hypersensitivity), periodontal disease, salivary alterations (i.e., hyposalivation and xerostomia), and oral mucosa-related complications in ED outpatients. Dental erosion, self-reported dentin hypersensitivity, hyposalivation, xerostomia, and angular cheilitis were found to be highly correlated with the vomiting behavior. CONCLUSIONS: ED outpatients were found to present a higher incidence of oral-related complications and an inferior oral health status, compared to gender- and age-matched controls. Alterations verified within outpatients were acknowledged to be quite similar to those previously reported within inpatients, in both of nature and severity, thus sustaining that the cranio-maxillofacial region is significantly affected by ED, even in the early/milder forms of the condition, as expectedly verified within outpatients. PMID- 29177815 TI - A Database Cohort Study to Assess the Risk of Angioedema Among Patients with Heart Failure Initiating Angiotensin-Converting Enzyme Inhibitors in the USA. AB - INTRODUCTION: Real-world evidence on the risk of angioedema associated with angiotensin-converting enzyme inhibitors (ACEIs) in patients with heart failure (HF) is scarce. OBJECTIVE: This non-interventional study aimed to estimate the incidence of and risk factors for angioedema in patients with HF initiating an ACEI in real-world practice. METHODS: This was a retrospective cohort study using claims data from the PharMetrics Plus database, supplemented with consumer health data, from 1 January 2007 to 31 March 2015. Patients with HF initiating an ACEI were followed up for a maximum of 1 year, until the first occurrence of angioedema or until cohort exit. Angioedema incidence rates were estimated and stratified by potential risk factors such as race, age, sex, and time from initiation of ACEI therapy. For each risk factor, the unadjusted and adjusted hazard ratio (HR) was calculated; exploratory analyses were carried out to account for all potential confounders. RESULTS: We identified 21,639 patients with HF initiating an ACEI (mean age 58 years; 35.6% women; mean follow-up 205 days). The 1-year incidence of angioedema per 1000 patient-years was 3.3 [95% confidence interval (CI) 2.4-4.5]. The incidence was higher in Black [6.2 (95% CI 3.1-12.5)] than in non-black [2.9 (95% CI 2.1-4.1)] patients, higher in women [5.2 (95% CI 3.4-7.9)] than in men [2.3 (95% CI 1.5-3.6)], and greatest in the first 30 days of ACEI therapy. CONCLUSIONS: The risk of angioedema in patients with HF initiating an ACEI observed in this study is in line with published estimates for the general patient population treated with ACEIs. PMID- 29177816 TI - Frames of Reference and Antecedentless Anaphora in Spanish Conversation. AB - This study examines native Spanish speakers' use of anaphoric pronouns and null subjects in conversational discourse in the absence of coreferential antecedents. It also considers the adequacy of Gundel et al.'s proposal (Language 69(2):274 307, 1993) that the cognitive status "in focus" corresponds with speakers' use of minimal referring expressions (i.e., unstressed pronouns and zeros). Analysis of naturally occurring Spanish conversation shows how the felicitous use and interpretation of non-canonical (antecedentless) anaphoric pronouns and null subjects are possible due to the activation of underlying cognitive frames that are shared by the interlocutors. Furthermore, the speaker's mention of a referent, dubbed a "neighborhood antecedent" by Langacker (Conceptual grouping and pronominal anaphora, in: Fox (ed) Studies in anaphora, Cambridge University Press, Cambridge, 1996), and the information "filled in" over the course of the conversation on account of the activation of relevant cognitive frames, both license and disambiguate the non-canonical anaphoric relations. PMID- 29177817 TI - Modulation of dual-task control with right prefrontal transcranial direct current stimulation (tDCS). AB - Executive functioning of two simultaneous component tasks in dual-task situations is primarily associated with activation of the lateral prefrontal cortex (PFC), as demonstrated in functional imaging studies. However, the precise role of the lateral PFC and the causal relation between this area's activity and executive functioning in dual tasks has exclusively been demonstrated for the left lateral PFC so far. To investigate this relation for the right lateral PFC, we used anodal transcranial direct current stimulation (atDCS; 1 mA, 20 min) in contrast to sham stimulation (1 mA, 30 s) in Experiment 1 (N = 30) as well as cathodal transcranial direct current stimulation (ctDCS; 1 mA, 20 min) in contrast to sham stimulation (1 mA, 30 s) in Experiment 2 (N = 25) over the right inferior frontal junction under conditions of random task order in dual tasks; random dual tasks require decisions on task order and thus high demands on executive functioning. Across these experiments, our results showed different tDCS-related effects: while atDCS improved performance evident from reduced error rates (Experiment 1), ctDCS impaired dual-task performance and increased these rates (Experiment 2). Moreover, baseline performance correlated with tDCS-induced performance changes, indicating that baseline performance was associated with atDCS-induced improvement. Our findings suggest that dual-task performance is causally related to right lateral PFC activation under conditions that require executive functioning as well as cognitive control of task sets and task order. PMID- 29177818 TI - Treatment of Cerebellar Ataxia in the Context of Systemic Diseases. AB - Purpose of review The purpose of this review is to assess the evidence behind treatment regimens for cerebellar ataxias occurring in the context of systemic disease. We will address systemic conditions which are associated with specific involvement of the cerebellum (rather than widespread nervous system involvement) and those conditions for which some degree of evidence of treatment response exists. Recent findings We have divided systemic disorders affecting the cerebellum into systemic immunological disorders, endocrine and metabolic disorders and paraneoplastic. Recent studies have increased understanding of the range of cerebellar disorders associated with a systemic immunological condition. The identification of newer pathogenic antibodies has improved diagnosis in conditions which would have previously been labelled as idiopathic. However, their rarity and phenotypic variability makes defining optimal immunomodulatory treatment regimens challenging. There is some evidence for beneficial effects of immunomodulation, particularly in anti-GAD ataxia and Hashimoto's encephalopathy, although, at this time, specific treatment regimens cannot be defined. Immune mediated paraneoplastic cerebellar disorders show response to therapy dependent, to some extent, on the underlying pathogenic antibody. Much is still to be understood concerning treatment regimens for the ataxic manifestations of metabolic disorders, notably alcohol-induced cerebellar injury, which are common and which are associated with significant disability. Summary Despite their rarity, cerebellar ataxias occurring in the context of systemic disease cause significant morbidity and better therapies are required to improve outcomes associated with these conditions. PMID- 29177819 TI - A case of chronic asymptomatic central pontine myelinolysis with histological evidence of remyelination. AB - Central pontine myelinolysis (CPM) is a neurological demyelinating disease of the pons. Although usually associated with rapid correction of hyponatremia, CPM may occur despite normonatremia, is often associated with chronic alcoholism and may be asymptomatic. Histological confirmation of asymptomatic CPM is rare. We describe an unusual post-mortem case of extensive but asymptomatic CPM in a chronic alcoholic patient with normonatremia. The affected part of the pons contained thinly myelinated axons with appearances supporting remyelination. We suggest that remyelination may account for the subclinical nature of this patient's CPM. PMID- 29177821 TI - Arterial aneurysms associated with intracranial dural arteriovenous fistulas: epidemiology, natural history, and management. A systematic review. AB - Arterial aneurysms are uncommon among patients with dural arteriovenous fistulae (DAVFs), and there is limited information available to guide treatment decisions in such cases. We performed a systematic review of the literature, including a case of a DAVF associated with a flow-related intraorbital ophthalmic artery (OA) aneurysm that we have recently managed. The purpose of our study was to clarify epidemiology, natural history, and management of these lesions. A total of 43 published cases of DAVF associated aneurysms were found in 26 studies on the topic. Anterior cranial fossa was the most common location (40%), and ethmoidal branches were the most common arterial feeders (55%). In about 63% of cases, the aneurysm was located on artery unrelated to DAVF supply. Approximately 10% of intracranial DAVFs were associated with aneurysms located in the intraorbital OA. Overall, 70% of lesions were Borden type III, and 50% of patients presented with hemorrhage. In approximately 17% of cases, the source of bleeding was a feeding artery aneurysm. All of the reported intraorbital OA aneurysms associated with DAVFs remained stable during follow-up. DAVF associated aneurysms are fairly rare. Anterior cranial fossa location and direct cortical venous drainage are common among these lesions. The aneurysms are less likely to be located on feeding arteries, and hemorrhagic presentation related to flow-related aneurysm rupture is uncommon. PMID- 29177820 TI - Single-use flexible ureteropyeloscopy: a systematic review. AB - PURPOSE: Data assessing the effectiveness of single-use flexible ureteropyeloscopy (FURS) are limited. This study evaluates and compares single use FURS with conventional reusable FURS. METHODS: A systematic search using electronic databases (Pubmed and Embase) was performed for studies evaluating single-use FURS in the setting of urinary tract stone disease. Outcome measures included a comparative evaluation of their mechanical, optical and clinical outcomes. RESULTS: Eleven studies on 466 patients met inclusion criteria. In vitro comparative data were available on three single-use flexible ureteropyeloscopes (LithoVueTM, PolyscopeTM and SemiFlexTM) and clinical data were available on two (LithoVueTM and PolyscopeTM). The overall stone-free rate and complication rate associated with single-use FURS was 87 +/- 15% and 9.3 +/- 9%, respectively. There were no significant differences in procedure duration, stone size, stone clearance and complication rates when single-use FURS and reusable FURS were compared (duration: 73 +/- 27 versus 74 +/- 13 min, p = 0.99; stone size: 1.36 +/- 0.2 versus 1.34 +/- 0.18 cm, p = 0.93; stone-free rate: 77.8 +/- 18 versus 68.5 +/- 33%, p = 0.76; complication rate 15.3 +/- 10.6 versus 15 +/- 1.6%, p = 0.3). CONCLUSIONS: Single-use FURS demonstrates comparable efficacy with reusable FURS in treating renal calculi. Further studies on clinical efficacy and cost are needed to determine whether single-use FURS will reliably replace its reusable counterpart. PMID- 29177822 TI - High-Resolution Crystallographic Analysis of AcrB Using Designed Ankyrin Repeat Proteins (DARPins). AB - X-ray crystallography is still the most prominent technique in use to decipher the 3D structures of membrane proteins. For successful crystallization, sample quality is the most important parameter that should be addressed. In almost every case, highly pure, monodisperse, and stable protein sample is a prerequisite. Vapor diffusion is in general the method of choice for obtaining crystals. Here, we discuss a detailed protocol for overproduction and purification of the inner membrane multidrug transporter AcrB and of DARPins, which are used for crystallization of the AcrB/DARPin complex, resulting in high-resolution diffraction and subsequent structure determination. PMID- 29177823 TI - Crystallographic Analysis of Drug and Inhibitor-Binding Structure of RND-Type Multidrug Exporter AcrB in Physiologically Relevant Asymmetric Crystals. AB - Xenobiotic extruding pumps have recently been known to be widely distributed in living organisms from mammalian to bacteria as a host-defense mechanism in cellular level. These pumps not only confer multidrug resistance of cancer cells and pathogenic bacteria but also cause hereditary diseases through the mutation. Our purposes are to elucidate the molecular structures and mechanisms of these xenobiotic exporters.We had succeeded to determine the crystal structure of bacterial major multidrug exporter AcrB at 3.5 A resolution (Murakami et al., Nature 419:587-593, 2002) and elucidated the structural bases of substrate recognition that the pump recognize the places and thus act as a "membrane vacuum cleaner." After that we also determined the crystal structure of the drug-binding form of AcrB in space group C2 in which asymmetric unit contains structurally asymmetric homo-trimer of AcrB (Murakami et al., Nature 443:173-179, 2006; Nakashima et al., Nature 480:565-569, 2011; Nakashima et al., Nature 500:120-126, 2013). Analyses revealed the existence of a specific mechanism to recognize numerous substrates that the multisite binding is the base of multidrug recognition rather than induced-fit, and functional-rotation mechanism in which three monomers undergo a strictly coordinated sequential conformational change cycle of access, binding, and extrusion. Determination of physiological asymmetric AcrB structure was crucially important to understand these transport mechanisms. PMID- 29177824 TI - Crystallographic Analysis of MATE-Type Multidrug Exporter with Its Inhibitors. AB - Multidrug exporters expressed in pathogens efflux substrate drugs such as antibiotics, and thus, the development of inhibitors against them has eagerly been anticipated. Furthermore, the crystal structures of multidrug exporters with their inhibitors provide novel insights into the inhibitory mechanism and the development of more specific and effective inhibitors. We previously reported the complex structures of the Multidrug And Toxic compound Extrusion (MATE)-type multidrug exporter with the macrocyclic peptides, which inhibit the efflux of substrates by the MATE-type multidrug exporter (Tanaka et al., Nature 496:247 251, 2013). In this chapter, we describe methodologies of the screening and synthesis of macrocyclic peptides as inhibitors, as well as the purification, crystallization, and structure determination of the complexes of the MATE-type multidrug exporter with its inhibitors. PMID- 29177825 TI - Crystallographic Analysis of the CusBA Heavy-Metal Efflux Complex of Escherichia coli. AB - Crystallization is one of the most successful techniques used to determine protein structure, especially for membrane proteins. However, the application of this technique is not straightforward and often hampered by the difficulties associated with expression, purification, and crystallization. Here we present our protocol and methodology for crystallizing the CusBA adaptor-transporter complex of Escherichia coli. Using these procedures, we were able to produce the first co-crystal structure of a resistance-nodulation-cell division (RND) transporter in complex with its associated membrane fusion protein. PMID- 29177826 TI - Purification of AcrAB-TolC Multidrug Efflux Pump for Cryo-EM Analysis. AB - The cell envelope of Gram-negative bacteria comprises an outer membrane, a cytoplasmic inner membrane, and an interstitial space. The tripartite multidrug transporter AcrAB-TolC, which uses proton electrochemical gradients to vectorially drive the efflux of drugs from the cell, spans this envelope. We describe here details of the methods used to prepare the recombinant tripartite assembly for high-resolution structure determination by cryo-EM. PMID- 29177827 TI - NMR Spectroscopy Approach to Study the Structure, Orientation, and Mechanism of the Multidrug Exporter EmrE. AB - Multidrug exporters are a class of membrane proteins that remove antibiotics from the cytoplasm of bacteria and in the process confer multidrug resistance to the organism. This chapter outlines the sample preparation and optimization of oriented solid-state NMR experiments applied to the study of structure and dynamics for the model transporter EmrE from the small multidrug resistance (SMR) family. PMID- 29177828 TI - Generation of Conformation-Specific Antibody Fragments for Crystallization of the Multidrug Resistance Transporter MdfA. AB - A major hurdle in membrane protein crystallography is generating crystals diffracting sufficiently for structure determination. This is often attributed not only to the difficulty of obtaining functionally active protein in mg amounts but also to the intrinsic flexibility of its multiple conformations. The cocrystallization of membrane proteins with antibody fragments has been reported as an effective approach to improve the diffraction quality of membrane protein crystals by limiting the intrinsic flexibility. Isolating suitable antibody fragments recognizing a single conformation of a native membrane protein is not a straightforward task. However, by a systematic screening approach, the time to obtain suitable antibody fragments and consequently the chance of obtaining diffracting crystals can be reduced. In this chapter, we describe a protocol for the generation of Fab fragments recognizing the native conformation of a major facilitator superfamily (MFS)-type MDR transporter MdfA from Escherichia coli. We confirmed that the use of Fab fragments was efficient for stabilization of MdfA and improvement of its crystallization properties. PMID- 29177829 TI - Biochemical Reconstitution and Characterization of Multicomponent Drug Efflux Transporters. AB - Efflux pumps are the major determinants in bacterial multidrug resistance. In Gram-negative bacteria, efflux transporters are organized as macromolecular tripartite machineries that span the two-membrane cell envelope of the bacterium. Biochemical data on purified proteins are essential to draw a mechanistic picture of this highly dynamical, multicomponent, efflux system. We describe protocols for the reconstitution and the in vitro study of transporters belonging to RND and ABC superfamilies: the AcrAB-TolC and MacAB-TolC efflux systems from Escherichia coli and the MexAB-OprM efflux pump from Pseudomonas aeruginosa. PMID- 29177830 TI - Covalently Linked Trimers of RND (Resistance-Nodulation-Division) Efflux Transporters to Study Their Mechanism of Action: Escherichia coli AcrB Multidrug Exporter as an Example. AB - Transporters undergo large conformational changes in their functional cycle. RND (Resistance-Nodulation-Division) family efflux transporters usually exist as homotrimers, and each protomer was proposed to undergo a cycle of conformational changes in succession so that at any given time the trimer would contain three protomers of different conformations, the functionally rotating mechanism of transport. This mechanism implies that the inactivation of one protomer among three will inactivate the entire trimeric ensemble by blocking the functional rotation. We describe a biochemical approach to test this prediction by first producing a giant protein in which the three protomers of Escherichia coli AcrB efflux pump are covalently linked together through linker sequences, and then testing for its function by inactivation of a single protomer unit. Inactivation can be done permanently by mutating a residue involved in proton relay, or in "real time" by using a protein in which one protomer contains two Cys residues on both sides of the large cleft in the periplasmic domain and then by rapidly inactivating this protomer with a methanethiosulfonate cross-linker. PMID- 29177831 TI - Determining Ligand Path Through a Major Drug Transporter, AcrB, in Escherichia coli. AB - An experimental approach to detect the path a substrate takes through a complex membrane protein is described with emphasis on technical approach and theoretical considerations. The protocols for bacterial culture preparation, membrane protein purification, fluorescent assay standardization, data collection, and data analysis are provided. Useful software tools are recommended. PMID- 29177832 TI - Molecular Modeling of Multidrug Properties of Resistance Nodulation Division (RND) Transporters. AB - Efflux pumps of the resistance nodulation division (RND) superfamily are among the major contributors to intrinsic and acquired multidrug resistance in Gram negative bacteria. Structural information on AcrAB-TolC and MexAB-OprM, major efflux pumps of Escherichia coli and Pseudomonas aeruginosa respectively, boosted intensive research aimed at understanding the molecular mechanisms ruling the active extrusion processes. In particular, several studies were devoted to the understanding of the determinants behind the extraordinary broad specificity of the RND transporters AcrB and MexB. In this chapter, we discuss the ever-growing role computational methods have been playing in deciphering key structural and dynamical features of these transporters and of their interaction with substrates and inhibitors. We further discuss and illustrate examples from our lab of how molecular docking, homology modeling, all-atom molecular dynamics simulations and in silico free energy estimations can all together give precious insights into the processes of recognition and extrusion of substrates, as well as on the possible inhibition strategies. PMID- 29177833 TI - A Transcriptomic Approach to Identify Novel Drug Efflux Pumps in Bacteria. AB - The core genomes of most bacterial species include a large number of genes encoding putative efflux pumps. The functional roles of most of these pumps are unknown, however, they are often under tight regulatory control and expressed in response to their substrates. Therefore, one way to identify pumps that function in antimicrobial resistance is to examine the transcriptional responses of efflux pump genes to antimicrobial shock. By conducting complete transcriptomic experiments following antimicrobial shock treatments, it may be possible to identify novel drug efflux pumps encoded in bacterial genomes. In this chapter we describe a complete workflow for conducting transcriptomic analyses by RNA sequencing, to determine transcriptional changes in bacteria responding to antimicrobials. PMID- 29177834 TI - Regulation of the Expression of Bacterial Multidrug Exporters by Two-Component Signal Transduction Systems. AB - Bacterial multidrug exporters confer resistance to a wide range of antibiotics, dyes, and biocides. Recent studies have shown that there are many multidrug exporters encoded in bacterial genome. For example, it was experimentally identified that E. coli has at least 20 multidrug exporters. Because many of these multidrug exporters have overlapping substrate spectra, it is intriguing that bacteria, with their economically organized genomes, harbor such large sets of multidrug exporter genes. The key to understanding how bacteria utilize these multiple exporters lies in the regulation of exporter expression. Bacteria have developed signaling systems for eliciting a variety of adaptive responses to their environments. These adaptive responses are often mediated by two-component regulatory systems. In this chapter, the method to identify response regulators that affect expression of multidrug exporters is described. PMID- 29177835 TI - Study of the Expression of Bacterial Multidrug Efflux Pumps in Anaerobic Conditions. AB - Bacterial multidrug efflux pumps belong to a class of membrane transporter proteins that dedicate to the extrusion of a diverse range of substances out of cells including all classes of currently available antibiotics. They constitute an important mechanism of bacterial antibiotic and multidrug resistance. Since many ecological niches of bacteria and the infection foci in animal host display low oxygen tension under which condition bacterial pathogens undergo fundamental changes on their metabolic modes, it is necessary to study the expression profiles of drug efflux pumps under these physiologically and clinically relevant conditions. In this chapter, we first introduce procedures to culture bacteria under anaerobic conditions, which is achieved using screw-capped Pyrex culture tubes without agitation. We then introduce beta-galactosidase activity assay using promoter-lacZ (encoding the beta-galactosidase enzyme) fusion to measure the expression of efflux pumps at transcriptional level, and Western blot using chromosomal FLAG-tagged construct to examine the expression of these proteins at translational level. Applications of these gene expression studies to reveal the regulatory mechanisms of efflux genes expression as well as their physiological functions are also discussed. PMID- 29177836 TI - Identification of a Staphylococcus aureus Efflux Pump Regulator Using a DNA Protein Affinity Technique. AB - In this chapter, we describe the step-by-step identification of a putative regulator protein and demonstrate the function of this protein as a repressor of the expression of a specific efflux pump, causing resistance to quinolones in Staphylococcus aureus. We show that the knockout gene mutant has an increase in transcript levels of the target efflux pump when compared to that of the S. aureus parental strain RN6390. We provide a detailed protocol that includes the identification of the DNA-binding transcriptional regulatory protein from S. aureus cell extracts using DNA sequences linked to magnetic beads. In addition, we describe the real-time qRT-PCR assays and MIC testing to evaluate the effects of the regulator on S. aureus drug resistance phenotype. PMID- 29177837 TI - High-Throughput Flow Cytometry Screening of Multidrug Efflux Systems. AB - The resistance nodulation cell division (RND) family of proteins are inner membrane transporters that associate with periplasmic adaptor proteins and outer membrane porins to affect substrate transport from the cytosol and periplasm in Gram-negative bacteria. Various structurally diverse compounds are substrates of RND transporters. Along with their notable role in antibiotic resistance, these transporters are essential for niche colonization, quorum sensing, and virulence as well as for the removal of fatty acids and bile salts. As such, RNDs are an attractive target for antimicrobial development. However, while enhancing the utility of antibiotics with an RND inhibitor is an appealing concept, only a small core of chemotypes has been identified as efflux pump inhibitors (EPIs). Thus, our key objective is the development and validation of an efflux profiling and discovery strategy for RND model systems. Here we describe a flow cytometric dye accumulation assay that uses fluorescein diacetate (FDA) to interrogate the model Gram-negative pathogens Escherichia coli, Franscisella tularensis, and Burkholderia pseudomallei. Fluorochrome retention is increased in the presence of known efflux inhibitors and in RND deletion strains. The assay can be used in a high-throughput format to evaluate efflux of dye-substrate candidates and to screen chemical libraries for novel EPIs. Triaged compounds that inhibit efflux in pathogenic strains are tested for growth inhibition and antibiotic potentiation using microdilution culture plates in a select agent Biosafety Level 3 (BSL3) environment. This combined approach demonstrates the utility of flow cytometric analysis for efflux activity and provides a useful platform in which to characterize efflux in pathogenic Gram-negative bacteria. Screening small molecule libraries for novel EPI candidates offers the potential for the discovery of new classes of antibacterial compounds.

AB - Emerging microtechnologies are aimed at developing a microsystem with densely packed array structure, i.e., an array with a femtoliter reaction chamber, for highly sensitive and quantitative biological assays. Here, we describe a novel femtoliter chamber array system (arrayed lipid bilayer chambers, ALBiC) that contains approximately a million femtoliter chambers, each sealed with a phospholipid bilayer membrane with extremely high efficiency (>90%). This novel platform enables detection of membrane transporter activity at the single molecule level and thus expands the applicability of femtoliter chamber arrays to highly sensitive assays of transporters.

AB - Measuring transport activity through reconstituted proteoliposomes is a key technique to resolve numerous problems found in the traditional methods. The system includes overexpression, purification, and reconstitution of transporters. Mixing of purified transporter with lipid and dilution below the critical micelle concentration result in rapid generation of proteoliposomes. Incubation of proteoliposomes in the presence of a driving force initiates substrate uptake. After starting the reaction, samples are passed through a gel filtration column to separate proteoliposomes from the reaction mixture. Here, we describe step-by step procedures for such reconstitution assays. PMID- 29177841 TI - Xanthogranulomatous pyelonephritis: a case with rare adhesion to pancreas. AB - Xanthogranulomatous pyelonephritis (XGP) is a rare benign condition with unknown aetiology and chronic infection of kidney. Commonly, most cases are related with urinary tract obstruction, nephrolithiasis, infection, diabetes, and/or immune compromise. XGP is associated with destruction of the renal parenchyma and granulomatous inflammation with foamy lipid-laden macrophages resulting from obstructive uropathy. It closely mimics a malignancy, exhibiting local tissue invasion and destruction. Adjacent organs especially duodenum as well as very rarely pancreas or spleen may be involved. Additionally, XGP is known as notorious for fistulisations, such as pyelocutaneous and ureterocutaneous fistulae, which have been reported as well described. XGP may be indistinguishable from renal cell carcinoma by radiographic and clinic consultation so it must be diagnosed based on the histopathologic examinations. Furthermore, macroscopic appearance of XGP is a mass of yellow tissue with focal haemorrhage besides necrosis and in this regard, it grossly resembles renal cell carcinoma. Here, we report the case of a 32-year-old female, preoperatively diagnosed as malignancy by clinical examination. Our further pathological evaluations revealed very rarely adhesion of XGP to pancreas tissue. PMID- 29177842 TI - Trifluridine-Tipiracil for Previously Treated Metastatic Colorectal Cancer: An Evidence Review Group Perspective of a NICE Single Technology Appraisal. AB - The National Institute for Health and Care Excellence (NICE) invited Servier, the company manufacturing trifluridine and tipiracil (T/T; trade name: Lonsurf(r)), to submit evidence for the clinical and cost effectiveness of T/T compared with best supportive care (BSC) for metastatic colorectal cancer (third-line or later). Kleijnen Systematic Reviews Ltd (KSR), in collaboration with Maastricht University Medical Center, was commissioned as the Evidence Review Group (ERG). This paper presents a summary of the company's submission (CS), the ERG report and the development of the NICE guidance for the use of this drug in England and Wales by the appraisal committee (AC). The ERG produced a critical review of the clinical and cost effectiveness of T/T based upon the CS. In the CS, pooled evidence of two trials (a phase II trial and RECOURSE) showed that T/T resulted in a significant increase in overall survival [OS; hazard ratio (HR) 0.67, 95% CI 0.58-0.78] and progression-free survival (PFS; HR 0.46, 95% CI 0.40-0.53). The AC considered the survival benefit of T/T clinically meaningful although relatively small. The ERG highlighted that none of the participants in the phase II trial and approximately half of the RECOURSE participants (394 of 800) were from Europe, which might limit the applicability of the study findings to the NHS. Moreover, the ERG's critical assessment of the company's economic evaluation highlighted a number of concerns that resulted in 11 adjustments to the company's base-case analysis. The ERG adjustments that had the largest impact were using the RECOURSE trial data only (instead of the pooled evidence), fixing errors and violations and using the utilities from the CORRECT trial (identified in the literature review) only. The ERG preferred to use the RECOURSE trial data only given the suboptimal methodology used by the company to pool the evidence. However, since there were no fundamental arguments to prevent the two trials from being pooled, the ERG also presented its base-case analysis based on the pooled effectiveness estimates. The company base-case resulted in an incremental cost effectiveness ratio (ICER) of L44,032 per QALY gained while the ERG base-case resulted in ICERs of L52,695 and L49,392 per QALY gained based on the RECOURSE trial only and pooled evidence, respectively. Since the AC concluded that the most plausible ICER was L49,392 per QALY gained, and that T/T meets end-of-life criteria, T/T was recommended as a cost effective use of NHS resources. PMID- 29177843 TI - Stabilising selection on immune response in male black grouse Lyrurus tetrix. AB - Illnesses caused by a variety of micro- and macro- organisms can negatively affect individuals' fitness, leading to the expectation that immunity is under positive selection. However, immune responses are costly and individuals must trade-off their immune response with other fitness components (e.g. survival or reproductive success) meaning that individuals with intermediate response may have the greatest overall fitness. Such a process might be particularly acute in species with strong sexual selection because the condition-dependence of male secondary sexual-traits might lead to striking phenotypic differences amongst males of different immune response levels. We tested whether there is selection on immune response by survival and reproduction in yearling and adult male black grouse (Lyrurus tetrix) following an immune challenge with a novel antigen and tested the hypothesis that sexual signals and body mass are honest signals of the immune response. We show that yearling males with highest immune response to these challenges had higher survival, but the reverse was true for adults. Adults with higher responses had highest mass loss and adult males with intermediate immune response had highest mating success. Tail length was related to baseline response in adults and more weakly in yearlings. Our findings reveal the complex fitness consequences of mounting an immune response across age classes. Such major differences in the direction and magnitude of selection in multiple fitness components is an alternative route underpinning the stabilising selection of immune responses with an intermediate immune response being optimal. PMID- 29177844 TI - Analysis of major paralogs encoding the Fra a 1 allergen based on their organ specificity in Fragaria * ananassa. AB - KEY MESSAGE: Fra a 1 protein in strawberry causes oral allergic syndrome. Over 39 Fra a 1 paralogs have been identified in strawberry genome. Fra a 1.01 is major accumulating protein in edible organs. Strawberry fruits contain allergenic proteins that cause oral allergic syndrome. The hypothesized major allergen is Fra a 1, an ortholog of the birch pollen allergen protein Bet v 1. We organized Fra a 1 genes and analyzed their localizations at the transcriptional and translational levels. In total, 15 new Fra a 1 proteins were identified from the genomic database, increasing the total number of Fra a 1 to 30 proteins encoded by 39 genes. Fra a 1.02 was mostly expressed in receptacles, and Fra a 1.01 in achenes, when analyzed by RNA sequencing. Immunoblotting showed that the Fra a 1.01 protein was broadly accumulated in strawberry organs, while the Fra a 1.02 protein was mostly expressed in receptacles. Recombinant Fra a 1.01 strongly reacted with human IgE. The mRNA and protein expression levels of Fra a 1 did not correlate, indicating the importance of protein levels when evaluating the abundance of allergens in strawberry. Based on the localizations, accumulation levels and reactivity to human IgE, we determined that Fra a 1.01 was the most important allergen, followed by Fra a 1.02, and then other Fra a 1 proteins. The information obtained here will be useful for selecting the target Fra a 1 paralogs when breeding hypoallergenic strawberry. PMID- 29177845 TI - Regulation of gaseous signaling molecules on proline metabolism in plants. AB - Proline accumulation plays an important role in the response and adaptation of plants to abiotic stress. Gaseous signaling molecules such as nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S) are involved in complicated events of cell signaling. However, the regulatory mechanisms of gaseous signaling molecules on proline synthesis and degradation are still unclear. This review summarized the biosynthesis and degradation of proline. The role of gaseous signaling molecules and their cross-talk on proline metabolic regulation in plants was discussed along with the future perspectives. PMID- 29177847 TI - Theoretical investigation of the effects of the molar ratio and solvent on the formation of the pyrazole-nitroamine cocrystal explosive 3,4-dinitropyrazole (DNP)/2,4,6,8,10,12-hexanitrohexaazaisowurtzitane (CL-20). AB - The effects of the molar ratio, temperature, and solvent on the formation of the cocrystal explosive DNP/CL-20 were investigated using molecular dynamics (MD) simulation. The cocrystal structure was predicted through Monte Carlo (MC) simulation and using first-principles methods. The results showed that the DNP/CL 20 cocrystal might be more stable in the molar ratio 1:1 near to 318 K, and the most probable cocrystal crystallizes in the triclinic crystal system with the space group P[Formula: see text]. Cocrystallization was more likely to occur in methanol and ethanol at 308 K as a result of solvent effects. The optimized structure and the reduced density gradient (RDG) of the DNP/CL-20 complex confirmed that the main driving forces for cocrystallization were a series of hydrogen bonds and van der Waals forces. Analyses of the trigger bonds, the charges on the nitro groups, the electrostatic surface potential (ESP), and the free space per molecule in the cocrystal lattice were carried out to further explore their influences on the sensitivity of CL-20. The results indicated that the DNP/CL-20 complex tended to be more stable and insensitive than pure CL-20. Moreover, an investigation of the detonation performance of the DNP/CL-20 cocrystal indicated that it possesses high power. Graphical abstract DNP/CL-20 cocrystal models with different molar ratios were investigated at different temperatures using molecular dynamics (MD) simulation methods. Binding energies and mechanical properties were probed to determine the stability and performance of each cocrystal model. Solvated DNP/CL-20 models were established by adding solvent molecules to the cocrystal surface. The binding energies of the models in various solvents were calculated in order to identify the most suitable solvent and temperature for preparing the cocrystal explosive DNP/CL-20. PMID- 29177846 TI - OPEN GLUME1: a key enzyme reducing the precursor of JA, participates in carbohydrate transport of lodicules during anthesis in rice. AB - KEY MESSAGE: OG1 is involved in JA-regulated anthesis by modulating carbohydrate transport of lodicules in rice. Flowering plants have evolved a sophisticated regulatory network to coordinate anthesis and maximize reproductive success. In addition to various environmental conditions, the plant hormone jasmonic acid and its derivatives (JAs) are involved in anthesis. However, the underlying mechanism remains largely unexplored. Here, we report a JA-defective mutant in rice (Oryza sativa), namely open glume 1, which has dysfunctional lodicules that lead to open glumes following anthesis. Map-based cloning and subsequent complementation tests confirmed that OG1 encodes a peroxisome-localized 12-oxo-phytodienoic acid reductase-a key enzyme that reduces the precursor of JA. Loss-of-function of OG1 resulted in almost no JA accumulation. Exogenous JA treatment completely rescued the defects caused by the og1 mutation. Further studies revealed that intracellular metabolism was disrupted in the lodicules of og1 mutant. At the mature plant stage, most seeds of the mutant were malformed with significantly reduced starch content. We speculate that JA or JA signaling mediates the carbohydrate transport of lodicules during anthesis, and signal the onset of cell degradation in lodicules after anthesis. We conclude that the OPEN GLUME 1 gene that produces a key enzyme involved in reducing the precursor of JA in JA biosynthesis and is involved in carbohydrate transport underlying normal lodicule function during anthesis in rice. PMID- 29177848 TI - Continued Use of a Single Antiplatelet Agent Does Not Increase the Risk of Delayed Bleeding After Colorectal Endoscopic Submucosal Dissection. AB - BACKGROUND: With the aging of the population and rising incidence of thromboembolic events, the usage of antiplatelet agents is also increasing. There are few reports yet on the management of antiplatelet agents for patients undergoing colorectal endoscopic submucosal dissection (ESD). AIMS: The aim of this study is to evaluate whether continued administration of antiplatelet agents is associated with an increased rate of delayed bleeding after colorectal ESD. METHODS: A total of 1022 colorectal neoplasms in 927 patients were dissected at Yokohama City University Hospital and its three affiliate hospitals between July 2012 and June 2017. We included the data of 919 lesions in the final analysis. The lesions were divided into three groups: the no-antiplatelet group (783 neoplasms), the withdrawal group (110 neoplasms), and the continuation group (26 neoplasms). RESULTS: Among the 919 lesions, bleeding events occurred in a total of 31 (3.37%). The rate of bleeding after ESD was 3.3% (26/783), 4.5% (5/110), and 0% (0/26), respectively. There were no significant differences in the rate of bleeding after ESD among the three groups (the withdrawal group vs. the no antiplatelet group, the continuation group vs. the no-antiplatelet group, and the withdrawal group vs. the continuation group). CONCLUSIONS: Continued administration of antiplatelet agents is not associated with any increase in the risk of delayed bleeding after colorectal ESD. Prospective, randomized studies are necessary to determine whether treatment with antiplatelet agents must be interrupted prior to colorectal ESD in patients who are at a high risk of thromboembolic events. PMID- 29177849 TI - Practice Patterns in Hepatitis B Virus Screening Before Cancer Chemotherapy in a Major US Hospital Network. AB - BACKGROUND: Cancer patients receiving chemotherapy face an increased risk of reactivation of chronic hepatitis B virus infection. AIM: To determine the HBV screening rate in patients receiving cancer chemotherapy in various clinical settings. METHOD: We identified 11,959 adult cancer patients (age >= 18 years) receiving parenteral chemotherapy between 2012 and 2015 within a major US hospital network, including a large university hospital, community teaching hospitals, and community oncology clinics. RESULT: Two thousand and forty-five patients (17.1%) were screened for either HBV surface antigen (HBsAg) or HBV core antibody (HBcAb) before chemotherapy, and 1850 patients (15.5%) had both HBsAg and HBcAb tested before chemotherapy. 8.4% were exposed to HBV, and 0.9% had chronic HBV infection (both HBsAg/HBcAb positive). Patients with hematologic tumor were more often screened than with solid tumor (55.6 vs. 8.3%, p < 0.001). Patients receiving chemotherapy with higher HBV reactivation risk had higher yet suboptimal HBV screening rate (41.1% B-depleting agents, 21.5% anthracycline, 14.9% steroid, 64.7% anti-TNF alpha and 18.6% other chemotherapy, p < 0.001). Patients with age >= 50 years (old 16.2% vs. young 23.9%, p < 0.001) and Asian ethnicity (Asian 13.6 vs. Caucasian 16.6%, p < 0.001) were screened less for HBV despite higher prevalence of HBV exposure (old 9.3% vs. young 4.3%, p < 0.001 and Asian 27.8% vs. Caucasian 6.4%, p < 0.001). Patients receiving chemotherapy in community oncology clinics were less screened versus community teaching hospitals or university hospital (12.7 vs. 19.1 vs. 19.7%, p < 0.001), despite similar prevalence of HBV infection. On multivariate analysis, receiving chemotherapy at a community oncology clinic [odds ratio (OR) 0.57, 95% confidence interval (CI) 0.45-0.72, p < 0.001] was independently associated with less HBV screening compared to receiving chemotherapy at a university or community teaching hospital. CONCLUSION: HBV screening among patients undergoing cancer chemotherapy was suboptimal and less commonly performed in community oncology clinics compared to teaching hospitals. PMID- 29177850 TI - A statistician's perspective on digital epidemiology. AB - We address the question "does digital epidemiology represent an epistemic shift in infectious disease epidemiology" from a statistician's viewpoint. Our main argument is that infectious disease epidemiology has not changed fundamentally as it always has been data-driven. However, as the data aspect has become more prominent, we discuss the statistical toolbox of the modern epidemiologist and argue that problem solving in the digital age, more than ever requires an interdisciplinary quantitative approach. PMID- 29177851 TI - Investigations into nematode parasites of goats in pastoral and crop livestock systems of Ethiopia. AB - We generated epidemiological information on the prevalence of nematode parasites and possible resistance/resilience of goats in three areas, Bati, Shinille, and Borana, of Ethiopia. A total of 350 breeding does were randomly selected and monitored for one year. Fecal egg counts (FEC), packed cell volume (PCV), body weight (BW), body condition score (BC), and fecal larvae identification were done. In Borana, the long rainy season had higher FEC, lower PCV, lower BC, and smaller BW compared to dry and short rainy seasons (p < 0.01). For Bati and Shinille, the differences between the seasons were significant (p < 0.01) but not clear-cut. Breed differences were also evident (p < 0.01) on FEC, PCV, and BW. The mean FEC for Borana goat was 158.5 +/- 1.12, whereas for Bati it was 38.9 +/- 1.12. Age differences did not have effect on FECs, PCV, and BC. No differences in parasite load, as reflected by FEC, was verified between male and female goats. In the wet season, large numbers of larvae were recovered from the study sites except for Bati. In the three sites, Haemonchus contortus followed by Trichostrongylus colubriformis were the dominant species. In the dry season, however, very little number of larvae was recovered, only of H. contortus in Bati and of H. contortus and T. colubriformis in Borana. Generally, the level of nematode infection was low. Therefore, nematode parasites are not a major problem and strategic control program using broad spectrum anthelmintic is not advisable. Rather, monitoring parasite load and selective de-worming should be sufficient to reduce productivity loses and pasture contamination. PMID- 29177852 TI - Emerging Concepts in Innate Immunity. AB - This review introduces recent concepts in innate immunity highlighting some of the latest exciting findings. These include: the discovery of the initiator of pyroptosis, Gasdermin D, and mechanisms of inflammatory caspases in innate immune signaling; the formation of oligomeric signalosomes downstream of innate immune receptors; mechanisms that shape innate immune responses, such as cellular homeostasis, cell metabolism, and pathogen viability; rapid methods of cell-to cell communication; the interplay between the host and its microbiome and the concept of innate immunological memory. Furthermore, we discuss open questions and illustrate how technological advances, such as CRISPR/Cas9, may provide important answers for outstanding questions in the field of innate immunity.

AB - Weighted gene co-expression network analysis (WGCNA) allows for the identification and characterization of cell type-specific gene modules in complex transcriptome datasets. Here, we use a microarray dataset of human macrophages comprising 29 conditions and 299 samples generated by differentiation of CD14+ monocytes into macrophages followed by in vitro stimulations to identify stimulation-specific gene modules. These gene modules can be used for experimental validation, as well as further bioinformatic analysis to determine key pathways or upstream transcription factors. PMID- 29177854 TI - Generation of Genetic Knockouts in Myeloid Cell Lines Using a Lentiviral CRISPR/Cas9 System. AB - CRISPR/Cas9-based gene targeting allows deletion of a gene of interest from cultured cell lines. Due to difficulty in transiently transfecting hematopoetic cells with components required for this process, we have adopted a lentiviral system for delivery of the CRISPR/Cas9 components into myeloid cell lines. Here, we detail the process of knocking out genes from pools of cultured myeloid cells using this CRISPR/Cas9 system and describe methods of validating these knockout pools. PMID- 29177855 TI - Modeling Primary Human Monocytes with the Trans-Differentiation Cell Line BLaER1. AB - Monocytes and macrophages play a pivotal role in the induction and shaping of immune responses. Expressing a broad array of pattern recognition receptors (PRRs), monocytes and macrophages constitute an integral component of the innate branch of the immune system. Traditionally, the majority of innate immune sensing and signaling pathways have been studied in macrophages of the murine system. This is largely due to the fact that genetic loss-of-function studies are amenable in this species. On the other hand, human cell lines of the monocyte macrophage cell lineage have been widely used to study myeloid cells in vitro. However, commonly utilized models (e.g., THP-1 cells) only mimic a limited spectrum of the immunobiology of primary human myeloid cells. Recently, we have explored the possibility to fill this gap with a human trans-differentiation cell culture system, in which lineage conversion from malignant B-lineage cells to monocytes/macrophages is caused by the inducible nuclear translocation of a C/EBPalpha transgene, BLaER1 cells. Using this model, we were able to characterize a novel inflammasome signaling entity that could not have been uncovered in the murine system or THP-1 cells. Here, we describe the handling of BLaER1 cells, providing a detailed protocol for their induced trans differentiation. We also provide data to demonstrate the applicability of the BLaER1 monocyte/macrophage system to study phagocytosis and various PRR cascades in human cells. PMID- 29177856 TI - Measurement of NF-kappaB Activation in TLR-Activated Macrophages. AB - Nuclear factor kappa-B (NF-kappaB) is a key transcription factor in the regulation of the innate immune inflammatory response in activated macrophages. NF-kappaB functions as a homo- or hetero-dimer derived from one or more of the five members of the NF-kappaB family, and is activated through a well-studied process of stimulus-dependent inhibitor degradation, post-translational modification, nuclear translocation, and chromatin binding. Its activity is subject to multiple levels of feedback control through both inhibitor protein activity and direct regulation of NF-kappaB components. Many methods have been developed to measure and quantify NF-kappaB activation. In this chapter, we summarize available methods and present a protocol for image-based measurement of NF-kappaB activation in macrophages activated with microbial stimuli. Using either a stably expressed GFP-tagged fusion of the RelA NF-kappaB protein, or direct detection of endogenous RelA by immunocytochemistry, we describe data collection and analysis to quantify NF-kappaB cytosol to nuclear translocation in single cells using fluorescence microscopy. PMID- 29177857 TI - Biochemical Isolation of the Myddosome from Murine Macrophages. AB - Ligand-induced macromolecular protein complex formation has emerged as a common means by which the innate immune system activates signal transduction pathways essential for host defense. Despite their structural divergence, key signaling molecules in diverse innate immune pathways mediate signal transduction by assembling higher-order protein complexes at specific subcellular locations in a stimulus-dependent manner. These protein complexes are collectively known as the supramolecular organizing centers (SMOCs), which link active receptors to a variety of downstream cellular responses. In the Toll-like receptor (TLR) pathway, the signaling adaptor MyD88 is the core of a SMOC called the myddosome, which is composed of the sorting adaptor TIRAP and the IRAK family kinases. Depending on the microbial ligands encountered, the myddosome can be assembled at the plasma membrane or endosomes, thereby leading to NF-KB and AP-1 activation, and the subsequent expression of pro-inflammatory cytokines. Herein, we provide a detailed protocol for studying myddosome assembly in murine bone marrow-derived macrophages (BMDMs). PMID- 29177858 TI - Generation of Innate Immune Reporter Cells Using Retroviral Transduction. AB - Innate immune cells are notoriously difficult to transfect; however, retroviruses can be used to stably integrate genes of interest into the host genome of primary or immortalized immune cells resulting in the generation of reporter cells. Here, we provide a detailed protocol covering the production of retroviruses, retroviral infection of innate immune target cells (including isolation and differentiation of murine bone marrow cells to macrophages), and several methods for enrichment of positively transduced cells. PMID- 29177859 TI - Examining Myddosome Formation by Luminescence-Based Mammalian Interactome Mapping (LUMIER). AB - Recent structural, biochemical, and functional studies have led to the notion that many of the post-receptor signaling complexes in innate immunity have a multimeric, multi-protein architecture whose hierarchical assembly is vital for function. The Myddosome is a post-receptor complex in the cytoplasmic signaling of Toll-like receptors (TLR) and the Interleukin-1 receptor (IL-1R), involving the proteins MyD88, IL-1R-associated kinase 4 (IRAK4), and IRAK2. Its importance is strikingly illustrated by the fact that rare germline mutations in MYD88 causing high susceptibility to infections are characterized by failure to assemble Myddosomes; conversely, gain-of-function MYD88 mutations leading to oncogenic hyperactivation of NF-kappaB show increased Myddosome formation. Reliable methods to probe Myddosome formation experimentally are therefore vital to further study the properties of this important post-receptor complex and its role in innate immunity, such as its regulation by posttranslational modification. Compared to structural and biochemical analyses, luminescence-based mammalian interactome mapping (LUMIER) is a straightforward, automatable, quantifiable, and versatile technique to study protein-protein interactions in a physiologically relevant context. We adapted LUMIER for Myddosome analysis and provide here a basic background of this technique, suitable experimental protocols, and its potential for medium-throughput screening. The principles presented herein can be adapted to other signaling pathways. PMID- 29177860 TI - Inflammatory Caspases: Activation and Cleavage of Gasdermin-D In Vitro and During Pyroptosis. AB - Gasdermin-D (also known as GSDMD), the newly identified executioner of pyroptotic cell death, is cleaved by activated caspase-1 downstream of canonical inflammasome activation or caspase-4, 5, and 11 upon their ligation and activation by cytosolic LPS. Upon a single cleavage between the two domains in Gasdermin-D, the N-terminal domain binds to membrane lipids and lyses cells by forming pores of an inner diameter of 10-14 nm within the membrane. The inter domain cleavage of Gasdermin-D is a reliable marker for the activation of inflammatory caspases and cell pyroptosis. Here, we describe the methods for examining Gasdermin-D cleavage by activated inflammatory caspases in vitro and upon inflammasome activation in vivo. PMID- 29177861 TI - Detection of ASC Speck Formation by Flow Cytometry and Chemical Cross-linking. AB - Assembly of a relatively large protein aggregate or "speck" formed by the adaptor protein ASC is a common downstream step in the activation of most inflammasomes. This unique feature of ASC allows its visualization by several imaging techniques and constitutes a reliable and feasible readout for inflammasome activation in cells and tissues. We have previously described step-by-step protocols to generate immortalized cell lines stably expressing ASC fused to a fluorescent protein for measuring inflammasome activation by confocal microscopy, and immunofluorescence of endogenous ASC in primary cells. Here, we present two more methods to detect ASC speck formation: (1) Assessment of ASC speck formation by flow cytometry; and (2) Chemical cross-linking of ASC followed by immunoblotting. These methods allow for the discrimination of inflammasome-activated versus non activated cells, the identification of lineage-specific inflammasome activation in complex cell mixtures, and sorting of inflammasome-activated cells for further analysis. PMID- 29177862 TI - Measuring Innate Immune Responses to Bacterial Viability. AB - The innate immune system directly senses microbial viability via the detection of a special class of viability-associated pathogen-associated molecular patterns (vita-PAMPs), such as prokaryotic messenger RNA. In the case of Gram-negative bacteria, detection of bacterial viability by phagocytes leads to a unique activation of inflammasome and type I interferon pathways, resulting in a robust pro-inflammatory innate response and a vigorous adaptive immune response. This protocol describes the methods required to study activation of both inflammasome and type I interferon pathways after stimulation of mouse bone marrow-derived macrophages with live or killed Gram-negative and Gram-positive bacteria. It covers the generation and handling of bone marrow-derived macrophages, the culture and killing of bacteria, the preparation of bacterial messenger RNA, and the stimulation of macrophages with live or killed bacteria. Lastly, this protocol describes the techniques employed to measure the hallmarks of inflammasome (secretion of interleukin-1beta) and type I interferon (activation of TBK1, IRF3 and secretion of type I interferon) pathways. PMID- 29177863 TI - Methods to Study Cell Swelling-Induced Inflammasome Activation. AB - Cells present ancestral conserved mechanisms to maintain their volume in response to alterations in environmental osmolarity. Changes in environmental osmolarities are therefore conserved as primitive stress signals. Innate immune cells, such as macrophages, express receptors to respond and shape immune response to stress, damage, or infection. The NLRP3 inflammasome is a multiprotein complex expressed in macrophages that senses pathogen- and danger-associated signals. The basic mechanisms of cell swelling and regulatory volume decrease are sensed by the NLRP3 inflammasome. Here, we present methods to study NLRP3 inflammasome activation in response to cell swelling. PMID- 29177864 TI - Detecting Release of Bacterial dsDNA into the Host Cytosol Using Fluorescence Microscopy. AB - Recognition of pathogens by the innate immune system relies on germline-encoded pattern recognition receptors (PRRs) that recognize unique microbial molecules, so-called pathogen-associated molecular patterns (PAMPs). Nucleic acids and their derivatives are one of the most important groups of PAMPs, and are recognized by a number of surface-associated as well as cytosolic PRRs. Cyclic GMP-AMP synthase (cGAS) recognizes the presence of pathogen- or host-derived dsDNA in the cytosol and initiates type-I-IFN production. Here, we describe a methodology that allows for evaluating the association of cGAS with released bacterial dsDNA during Francisella novicida infection of macrophages, by fluorescence confocal microscopy. This method can be adapted to the study of cGAS-dependent responses elicited by other intracellular bacterial pathogens and in other cell types. PMID- 29177865 TI - Quantitative Proteomics of Secreted Proteins. AB - Secreted proteins such as cytokines, interleukins, growth factors, and hormones have pleiotropic functions and facilitate intercellular communication in organisms. Quantification of these proteins conventionally relies on antibody based methods, i.e., enzyme-linked immunosorbent assays (ELISA), whose large scale use is limited by availability, specificity, and affordability.Here, we describe an experimental and bioinformatics workflow to comprehensively quantify cellular protein secretion by mass spectrometry. Secreted proteins are collected in vitro or ex vivo, digested with proteases and the resulting peptide mixtures are analyzed in single liquid chromatography-mass spectrometry (LC-MS/MS) runs. Label-free quantification and bioinformatics analysis is conducted in the MaxQuant and Perseus computational environment. Our workflow allows the quantification of thousands of secreted proteins spanning a concentration range of four orders of magnitude and permits the systems-level characterization of secretory programs as well as the discovery of proteins with unexpected extracellular functions.

During caspase-1-mediated cell death, termed pyroptosis, pro-inflammatory mediators that lack canonical secretory signal sequences, such as interleukin-1beta (IL-1beta), are released into the extracellular environment. To define whether cell death is required for the release of IL-1beta, or if IL-1beta can be actively secreted from viable cells, we have developed a modified IL-1beta Enzyme-Linked ImmunoSpot (ELISpot) assay. This assay simultaneously detects cellular viability and IL-1beta release at the single-cell level, and is therefore useful to examine how cell death influences IL-1beta secretion under different experimental conditions. Cells expressing a surrogate viability marker, such as GFP, are plated onto cellulose filter plates coated with an IL-1beta capture antibody. This antibody immobilizes IL-1beta as it is released from cells, allowing detection of distinct IL-1beta "spots." Both GFP positive cells and IL-1beta spots are detected and quantified using an AID ELISpot Reader, and the captured images are overlaid. Therefore, cell viability and IL-1beta release from individual cells can be monitored visually. We have recently used this method to document how individual fibroblasts expressing activated caspase-1 can secrete IL-1beta in the absence of cell death. Adaptation of this assay to other experimental conditions may help to define the circumstances where cell death influences IL-1beta release and IL-1beta-driven inflammatory responses.

AB - During infection, the cytosolic detection of viral double-stranded RNA (dsRNA) leads to the oligomerization and activation of mitochondrial antiviral signaling protein (MAVS) and the subsequent production of type I interferon (IFN). Here, we describe a novel method of visualizing and quantifying the aggregation of MAVS in response to dsRNA stimulation or viral infection in vitro using confocal microscopy. PMID- 29177868 TI - alpha-Methyl artoflavanocoumarin from Juniperus chinensis exerts anti-diabetic effects by inhibiting PTP1B and activating the PI3K/Akt signaling pathway in insulin-resistant HepG2 cells. AB - Diabetes mellitus is one of the greatest global health issues and much research effort continues to be directed toward identifying novel therapeutic agents. Insulin resistance is a challenging integrally related topic and molecules capable of overcoming it are of considerable therapeutic interest in the context of type 2 diabetes mellitus (T2DM). Protein tyrosine phosphatase 1B (PTP1B) negatively regulates insulin signaling transduction and is regarded a novel therapeutic target in T2DM. Here, we investigated the inhibitory effect of alpha methyl artoflavanocoumarin (MAFC), a natural flavanocoumarin isolated from Juniperus chinensis, on PTP1B in insulin-resistant HepG2 cells. MAFC was found to potently inhibit PTP1B with an IC50 of 25.27 +/- 0.14 uM, and a kinetics study revealed MAFC is a mixed type PTP1B inhibitor with a K i value of 13.84 uM. Molecular docking simulations demonstrated MAFC can bind to catalytic and allosteric sites of PTP1B. Furthermore, MAFC significantly increased glucose uptake and decreased the expression of PTP1B in insulin-resistant HepG2 cells, down-regulated the phosphorylation of insulin receptor substrate (IRS)-1 (Ser307), and dose-dependently enhanced the protein levels of IRS-1, phosphorylated phosphoinositide 3-kinase (PI3K), Akt, and ERK1. These results suggest that MAFC from J. chinensis has therapeutic potential in T2DM by inhibiting PTP1B and activating insulin signaling pathways. PMID- 29177869 TI - Functional analysis of a regulator of G-protein signaling CgRGS1 in the rubber tree anthracnose fungus Colletotrichum gloeosporioides. AB - Colletotrichum gloeosporioides is the causal agent of rubber anthracnose, which is also one of the important biological factors threatening the development of natural rubber industry in the world. Regulators of G-protein signaling (RGS) are key negative regulators of G-proteins, which play important roles in growth, development and pathogenic processes of plant pathogens. In this study, a RGS gene CgRGS1 was functionally characterized in C. gloeosporioides. Compared to the wild type, the CgRGS1 deletion mutant had slow vegetative growth, reduced conidia with multi-end germination, low appressorium formation rate, high resistance to oxidative stress and SDS. Moreover, the mutant was sensitive to osmotic pressure and showed decreased virulence. In conclusion, CgRGS1 is involved in regulation of vegetative growth, conidiation, germination, appressorium formation, oxidative stress, osmotic pressure response and pathogenicity in C. gloeosporioides. PMID- 29177871 TI - Tumour functional sphericity from PET images: prognostic value in NSCLC and impact of delineation method. AB - PURPOSE: Sphericity has been proposed as a parameter for characterizing PET tumour volumes, with complementary prognostic value with respect to SUV and volume in both head and neck cancer and lung cancer. The objective of the present study was to investigate its dependency on tumour delineation and the resulting impact on its prognostic value. METHODS: Five segmentation methods were considered: two thresholds (40% and 50% of SUVmax), ant colony optimization, fuzzy locally adaptive Bayesian (FLAB), and gradient-aided region-based active contour. The accuracy of each method in extracting sphericity was evaluated using a dataset of 176 simulated, phantom and clinical PET images of tumours with associated ground truth. The prognostic value of sphericity and its complementary value with respect to volume for each segmentation method was evaluated in a cohort of 87 patients with stage II/III lung cancer. RESULTS: Volume and associated sphericity values were dependent on the segmentation method. The correlation between segmentation accuracy and sphericity error was moderate (|rho| from 0.24 to 0.57). The accuracy in measuring sphericity was not dependent on volume (|rho| < 0.4). In the patients with lung cancer, sphericity had prognostic value, although lower than that of volume, except for that derived using FLAB for which when combined with volume showed a small improvement over volume alone (hazard ratio 2.67, compared with 2.5). Substantial differences in patient prognosis stratification were observed depending on the segmentation method used. CONCLUSION: Tumour functional sphericity was found to be dependent on the segmentation method, although the accuracy in retrieving the true sphericity was not dependent on tumour volume. In addition, even accurate segmentation can lead to an inaccurate sphericity value, and vice versa. Sphericity had similar or lower prognostic value than volume alone in the patients with lung cancer, except when determined using the FLAB method for which there was a small improvement in stratification when the parameters were combined. PMID- 29177870 TI - Dosimetric parameters predicting contralateral liver hypertrophy after unilobar radioembolization of hepatocellular carcinoma. AB - PURPOSE: This study aimed at identifying prior therapy dosimetric parameters using 99mTc-labeled macro-aggregates of albumin (MAA) that are associated with contralateral hepatic hypertrophy occurring after unilobar radioembolization of hepatocellular carcinoma (HCC) performed with 90Y-loaded glass microspheres. METHODS: The dosimetry data of 73 HCC patients were collected prior to the treatment with 90Y-loaded microspheres for unilateral disease. The injected liver dose (ILD), the tumor dose (TD) and healthy injected liver dose (HILD) were calculated based on MAA quantification. Following treatment, the maximal hypertrophy (MHT) of an untreated lobe was calculated. RESULTS: Mean MHT was 35.4 +/- 40.4%. When using continuous variables, the MHT was not correlated with any tested variable, i.e., injected activity, ILD, HILD or TD except with a percentage of future remnant liver (FRL) following the 90Y-microspheres injection (r = -0.56). MHT >= 10% was significantly more frequent for patients with HILD >= 88 Gy, (52% of the cases), i.e., in 92.2% versus 65.7% for HILD < 88 Gy (p = 0.032). MHT >= 10% was also significantly more frequent for patients with a TD >= 205 Gy and a tumor volume (VT) >= 100 cm3 in patients with initial FRL < 50%. MHT >=10% was seen in 83.9% for patients with either an HILD >= 88 Gy or a TD >= 205 Gy for tumors larger than 100cm3 (85% of the cases), versus only 54.5% (p = 0.0265) for patients with none of those parameters. MHT >=10% was also associated with FRL and the Child-Pugh score. Using multivariate analysis, the Child-Pugh score (p < 0.0001), FRL (p = 0.0023) and HILD (p = 0.0029) were still significantly associated with MHT >=10%. CONCLUSION: This study demonstrates for the first time that HILD is significantly associated with liver hypertrophy. There is also an impact of high tumor doses in large lesions in one subgroup of patients. Larger prospective studies evaluating the MAA dosimetric parameters have to be conducted to confirm these promising results.

AB - We performed morphological analysis of the effect of the peptide complex from porcine kidneys on the course of experimental urolithiasis modeled in rats by treatment with 1% ethylene glycol solution (in drinking water) for 6 weeks. The peptide complex obtained by acetic acid extraction was administered in a dose of 15 mg. Administration of the peptide complex to animals with experimental kidney stone disease leads to 100% destruction of large and medium stones to the "dust" granularity. PMID- 29177874 TI - The Role of the Glutathione System in Oxidative Modification of Proteins and Dysregulation of Apoptosis in Jurkat Tumor Cells. AB - We compared changes in the redox status and intensity of oxidative modification of proteins in intact Jurkat tumor cells and cells cultured with buthionine sulfoximine, an inhibitor of the key enzyme of glutathione synthesis gamma glutamylcysteine synthetase. The glutathione system components play a role in modulation of the content of protein-bound glutathione, protein carbonyl derivatives, bityrosine, and oxidized tryptophan, and in dysregulation of apoptosis in Jurkat tumor cells. Inhibition of de novo synthesis of glutathione in Jurkat tumor cells was followed by accumulation of hydroxyl radical, a reduction in the level of protein-bound glutathione and oxidized tryptophan, and a rise in the concentration of protein carbonyl derivatives. These changes were accompanied by activation of programmed cell death. PMID- 29177873 TI - Biodistribution of Alpha-Fetoprotein-Containing Noncovalent Complex Aimpila with Antitumor Activity. AB - Biodistribution of [125I]Aimpila (20 mg/kg) in the tumor and normal tissues, including the mammary gland tissue, after single oral dose was studied in BALB/c nude mice with T47D/ReCAF+++ human breast tumor sensitive to this drug and in closely related BALB/c nude+mice without tumors. The maximum concentration of [125I]Aimpila was in fact the same in the tumor and in the mammary gland, while the time course of its accumulation/elimination differed. The time of the maximum accumulation of the drug in the tumor was shorter and its persistence longer than in normal tissue. After 24 h, label concentration in the tumor was 4.5 times higher (p=0.002). Differences in the time course of label accumulation in the tumor were detected. The maximum ratio of tumor/blood concentrations of the preparation was recorded in 1 h after administration. [125I]Aimpila and [125I]alpha-fetoprotein accumulated in the tumor in comparable concentrations and were eliminated simultaneously at the same rate. The results of comparative analysis of accumulation of the labeled compounds in Aimpila-sensitive T47D/RECAF+++ tumor from 0.5 to 9.0 h after drug administration could be interpreted as a result of possible receptor-mediated binding of the complex with the tumor at the expense of the alpha-fetoprotein transporting part. Differences in the parameters of [125I]Aimpila biodistribution in the tumor and normal mammary tissue indirectly attested to selective antiproliferative activity of the complex. PMID- 29177875 TI - Peculiarities of Cell Seeding on Polylactic Acid-Based Scaffolds Fabricated Using Electrospinning and Solution Blow Spinning Technologies. AB - We studied the possibility of seeding bone marrow-derived stromal cells onto polylactic acid-based scaffolds fabricated by electrospinning and solution blow spinning technologies. The cells were applied to the scaffolds by dynamic seeding and scaffolds were then cultured in Petri dishes in culture medium for 3 days. Cell migration to the Petri dish surface was noted only for scaffolds fabricated by electrospinning technology, but DAPI staining confirmed the presence of cells in both scaffolds. The mean number of cells in scaffolds fabricated by electrospinning and solution blow spinning was 56+/-9 and 81+/-6, respectively. The scaffold fabricated by solution blow spinning was more effectively (p<0.05) colonized by cells due to its more optimal spatial structure. PMID- 29177876 TI - Bioluminescent Study of the Distribution of High-Molecular-Weight Protein Fraction of Cellex Daily Preparation in the Brain after Intranasal Administation. AB - Permeability of the blood-brain barrier for protein fractions 50-100 kDa (PF50 100) of Cellex Daily preparation labeled with fluorescent tracer FITC and non conjugated FITC were compared after intranasal administration of the preparations to healthy rats. Fluorimetrical analysis of the serum and cerebrospinal fluid samples showed that Cellex Daily PF50-100-FITC administered intranasally penetrated into the blood and cerebrospinal fluid with maximum accumulation in 2 h after administration and persists in the circulation for 24 h probably due to binding with plasma proteins. The differences in the kinetic profile of PF50-100 FITC and free FITC indirectly suggest that the major part of the preparation is not degraded within 24 h and FITC is probably not cleaved from the protein components of the preparation. In vivo fluorescence analysis showed significant fluorescent signal in the olfactory bulbs in 6 h after intranasal administration; hence, the preparation administered via this route can bypass the blood-brain barrier. Scanning laser confocal microscopy of rat brain sections confirmed penetration of the high-molecular weight protein fraction PF50-100-FITC into CNS structures. The most pronounced accumulation of the labeled drug was observed in the olfactory bulb in 6 and 12 h after administration. In contrast to free FITC administered in the control group, significant accumulation of PF50-100-FITC in the olfactory cortex and frontal cortex neurons with functionally active nuclei was observed in 6, 12 and 24 h after intranasal administration.

AB - Regenerative activity of locally applied drugs based on copper nanoparticles was compared on white male rats with an experimental purulent wound infected with clinical polyantibiotic resistant strains of Staphylococcus aureus. The use of a suspension of copper nanoparticles and complex drugs based on chitosan and starch with copper nanoparticles led to a rapid reduction of the wound area and elimination of the wound-contaminating agent, which confirmed high antibacterial and regenerative activity of copper nanoparticles in the composition of the studied drugs.

AB - The anterior mediastinal lymph nodes were analyzed morphometrically in rats with chemically provoked breast cancer. Rats with untreated breast cancer and animals receiving chemotherapy demonstrated decreased volumes of paracortical region and lymphoid nodules with the germinal centers accompanied by extended medullary thymic substance. Resection of largest focus of breast tumor improved the filtration barrier potential of anterior mediastinal lymph nodes, up-regulated the proliferative activity of lymphoid cells in T-cell zones, and down-regulated proliferation of plasmatic cells.

AB - We performed comparative analysis of the morphology of chondrocytes in normal cartilage, after their isolation from the tissue, and at different stages of culturing; structural dynamics of cells during culturing was also studied. Significant morphological differences in chondrocytes at the specified stages of their preparation to in vivo use were revealed. Pronounced structural changes (blebbing and cytoplasm swelling) were found in chondrocytes before their implantation, which can affect the formation of cartilage regenerate. The study was performed using light microscopy methods including time-lapse recording of the cell cultures with differential interference Nomarski contrasting combined with transmission electron microscopy. PMID- 29177880 TI - Regeneration Potential of Lymphoid Tissue of Small Intestine in Mice after Exposure to Low-Intensity Radiation. AB - Number and size of aggregated lymphoid nodules in the small intestine of mice exposed to radiation using a gamma-irradiation unit GOBO-60 with 137Cs source were measured using the methods of visual microscopy and morphometry. Morphological status of the nodules was estimated on days 4, 28, 60, and 90 after the exposure. Significant changes were observed in the lymphoid system of the small intestine after exposure to low-intensity radiation. The size of aggregated lymphoid nodules decreased and the relative number of cells with degenerative changes increased. Regenerative processes were observed as soon as on day 4 of the rehabilitation period. However, the number and sizes of aggregated lymphoid nodules (length, width, and section area), and the ratio of lymphoid nodules with germinal center were still lower than in the control. The number of cells forming lymphoid interstitial plaques was close to the control on days 28-90 of the rehabilitation process.

AB - The ultrastructure of nephrocytes of the proximal and distal convoluted tubules, podocytes, mesangial cells, and macrophages of the interstitial connective tissue was studied after single intravenous administration of magnetite nanoparticles modified with chitosan (magnetic nanospheres) or lipids (magnetic liposomes). Transmission electron microscopy showed ultrastructural features of absorption of magnetite nanoparticles. The shape, size, and number of vesicles containing nanoparticles in nephrocytes of convoluted tubules and macrophages after administration of the suspensions of magnetic nanospheres and magnetic liposomes were described. PMID- 29177882 TI - Effect of the Natural Cytokine Complex on the Structure and Metabolism of Contractile Myocardium Normally and under Increased Hemodynamic Load. AB - Effect of natural complex of cytokines with activity of IL-1, IL-2, IL-6, TNF, MIF, GTFbeta on the structure and metabolism of contractile ventricular cardiomyocytes was assessed in the control and under conditions of acute experimental aortic stenosis. Systemic administration of the complex in the control had no significant effect on myocardial morphology with low number of damaged cardiomyocytes and low degree of structural damage. Administration of the cytokine complex against the background of aortic stenosis did not exert any additional alterative effect on cardiomyocytes, structural damage of contractual nature was moderate. Systemic administration of the natural cytokine complex had a pronounced inhibitory effect on metabolic processes in the myocardium of both ventricles both in the control and against the background of increased hemodynamic load. In cardiomyocytes, glycolysis and citric acid cycle were slowed down, oxidation of free fatty acids and their metabolic products was inhibited as well as shuttle mechanisms and biosynthetic reactions. Inhibition of energy producing processes is the cause of the lack of the contractile function energy supply and can worsen the course of cardiovascular diseases and increase the risk of their complications in conditions, accompanied by increased blood cytokine level. PMID- 29177883 TI - Non-Competitive NMDA Receptor Antagonist Hemantane Reduces Ethanol Consumption in Long-Term Alcohol Experienced Rats. AB - Activity of hemantane, an amino adamantane derivative, exhibiting the properties of lowaffinity non-competitive NMDA receptor antagonist, was evaluated in experimental in vivo models of alcoholism. Hemantane had no effects on the formation and manifestation of behavioral sensitization to ethanol in DBA/2 mice. Under conditions of free choice between 10% ethanol and water, hemantane (20 mg/kg/day for 14 days, intraperitoneally) significantly reduced the daily ethanol intake in random-bred male rats with formed alcohol motivation (>4 g/kg of ethanol). During modelling of withdrawal syndrome, hemantane administered intraperitoneally in doses of 5-20 mg/kg dose-dependently attenuated alcohol deprivation effect after acute withdrawal with no effects on protracted abstinence. It was found that hemantane suppressed alcohol drinking behavior in long-term ethanol experienced rats and attenuated alcohol-seeking behavior after acute withdrawal. PMID- 29177884 TI - Oxidative Stress as a Mechanisms of Reduced Glucose Absorption under Conditions of Immobilization Stress. AB - Experimental studies demonstrated inhibition of glucose absorption in the jejunum in acute and chronic 1-h daily immobilization stress, with the maximum inhibition on day 7 of immobilization. These changes correlate with the development of oxidative stress in animals over the entire duration of the experiment, which manifested by an increase in the content of the primary and end LPO products and decrease of the total antioxidant activity of the blood. Correction of these shifts with the antioxidant drug inhibits accumulation of LPO products and increases antioxidant defense and glucose absorption rate. These data prove the important role of peroxidation in regulation of glucose absorption. PMID- 29177886 TI - Production of poly-gamma-glutamic acid by a thermotolerant glutamate-independent strain and comparative analysis of the glutamate dependent difference. AB - Poly-gamma-glutamic acid (gamma-PGA) is a promising microbial polymer with wide applications in industry, agriculture and medicine. In this study, a novel glutamate-independent gamma-PGA producing strain with thermotolerant characteristics was isolated and identified as Bacillus subtilis GXG-5, then its product was also characterized. The fermentation process was optimized by single factor tests, and results showed that high temperature (50 degrees C) was especially suitable for the gamma-PGA production by GXG-5. The gamma-PGA yield reached 19.50 +/- 0.75 g/L with substrate conversion efficiency of 78% at 50 degrees C in 10 L fermentor. Comparison of GXG-5 and GXA-28 (glutamate-dependent strain) under respective optimal fermentation conditions, the gamma-PGA yield of GXG-5 was 19.0% higher than that of GXA-28, and GXG-5 was also superior to GXA-28 in the availability of carbon sources and substrates. Furthermore, the glutamate dependent difference between GXA-28 and GXG-5 was analyzed by genomic sequencing, results indicated that genes related to the glutamate dependent difference mainly involved in carbohydrate transport and metabolism and amino acid metabolism, and 13 genes related to gamma-PGA synthesis were mutated in GXG-5. This study provided a potential glutamate-independent strain to replace glutamate-dependent strain for gamma-PGA production, and shared novel information for understanding the glutamate dependent difference at the genomic level. PMID- 29177885 TI - Clopidogrel Therapy in Patients with Cardiovascular Disease Undergoing Transurethral Resection of the Prostate: A Step Towards Individualization. AB - OBJECTIVES: The objective of this study was to test platelet function pre- and peri-operatively in clopidogrel-treated patients undergoing transurethral resection of the prostate. METHODS: This was a pilot study involving 20 male patients treated with clopidogrel (75 mg/day) for the secondary prevention of cardiovascular disease and scheduled for elective transurethral resection of the prostate. Platelet function testing with light transmittance aggregometry in platelet-rich plasma of four samples (T0, T1, T2, and T3 drawn on the same day, 3 and 7 days of clopidogrel cessation and 24-h post-operatively, respectively) was performed and evaluated in each patient. P-selectin membrane expression was evaluated using monoclonal antibodies. RESULTS: The platelet response to adenosine diphosphate 5 uMU and 20 uMU at T0 were 42 +/- 15 and 60 +/- 14%, respectively. After discontinuation of clopidogrel, corresponding maximum aggregation values at T1 were 60 +/- 16 and 74 +/- 14%, and increased to 69 +/- 16 and 79 +/- 18% at T2. No significant difference in platelet aggregation values were noted between T1 and T2, while similar aggregation values were recorded at T3. CONCLUSIONS: Our findings indicate that in patients undergoing transurethral resection of the prostate, platelet activation is similar 3 and 7 days from clopidogrel cessation. These results may be of relevance in subjects at increased thrombotic risk prior to a surgical procedure carrying a high-bleeding risk. PMID- 29177887 TI - FreB is involved in the ferric metabolism and multiple pathogenicity-related traits of Verticillium dahliae. AB - Ferric reductases are integral membrane proteins involved in the reduction of environmental ferric iron into the biologically available ferrous iron. In the most overwhelming phytopathogenic fungus, Verticillium dahliae, these ferric reductase are not studied in details. In this study we explored the role of FreB gene (VDAG_06616) in the ferric reduction and virulence of V. dahliae by generating the knockout mutants (DeltaFreB) and complementary strains (DeltaFreB C) using protoplast transformation. When cultured on media supplemented with FeSO4, FeCl3 and no iron, DeltaFreB exhibited significantly reduced growth and spore production especially on media with no iron. Transmembrane ferric reductase activity of DeltaFreB was decreased up to 50% than wild type strains (Vd-wt). The activity was fully restored in DeltaFreB-C. Meanwhile, the expression levels of other related genes (Frect-4, Frect-5, Frect-6 and Met) were obviously increased in DeltaFreB. Compared with the Vd-wt and DeltaFreB-C, DeltaFreB-1 and DeltaFreB 2 were impaired in colony diameter and spore number on different carbon sources (starch, sucrose, galactose and xylose). DeltaFreB-1 and DeltaFreB-2 were also highly sensitive to oxidative stress as revealed by the plate diffusion assay when 100 uM H2O2 was applied to the fungal culture. When Nicotiana benthamiana plants were inoculated, DeltaFreB exhibited less disease symptoms than Vd-wt and DeltaFreB-C. In conclusion, the present findings not only indicate that FreB mediates the ferric metabolism and is required for the full virulence in V. dahliae, but would also accelerate future investigation to uncover the pathogenic mechanism of this fungus.

PMID- 29177888 TI - Benchmark dose analyses of multiple genetic toxicity endpoints permit robust, cross-tissue comparisons of MutaMouse responses to orally delivered benzo[a]pyrene. AB - Genetic damage is a key event in tumorigenesis, and chemically induced genotoxic effects are a human health concern. Although genetic toxicity data have historically been interpreted using a qualitative screen-and-bin approach, there is increasing interest in quantitative analysis of genetic toxicity dose-response data. We demonstrate an emerging use of the benchmark dose (BMD)-approach for empirically ranking cross-tissue sensitivity. Using a model environmental carcinogen, we quantitatively examined responses for four genetic damage endpoints over an extended dose range, and conducted cross-tissue sensitivity rankings using BMD100 values and their 90% confidence intervals (CIs). MutaMouse specimens were orally exposed to 11 doses of benzo[a]pyrene. DNA adduct frequency and lacZ mutant frequency (MF) were measured in up to 8 tissues, and Pig-a MF and micronuclei (MN) were assessed in immature (RETs) and mature red blood cells (RBCs). The cross-tissue BMD pattern for lacZ MF is similar to that observed for DNA adducts, and is consistent with an oral route-of-exposure and differences in tissue-specific metabolism and proliferation. The lacZ MF BMDs were significantly correlated with the tissue-matched adduct BMDs, demonstrating a consistent adduct conversion rate across tissues. The BMD CIs, for both the Pig-a and the MN endpoints, overlapped for RETs and RBCs, suggesting comparable utility of both cell populations for protracted exposures. Examination of endpoint-specific response maxima illustrates the difficulty of comparing BMD values for a fixed benchmark response across endpoints. Overall, the BMD-approach permitted robust comparisons of responses across tissues/endpoints, which is valuable to our mechanistic understanding of how benzo[a]pyrene induces genetic damage. PMID- 29177890 TI - AREDS simplified severity scale as a predictive factor for response to aflibercept therapy for typical neovascular age-related macular degeneration. AB - PURPOSE: To investigate whether the severity of the condition in the untreated fellow eye is a predictive factor for the response to intravitreal aflibercept injection (IAI) for exudative age-related macular degeneration (AMD). METHODS: A retrospective medical chart review was conducted for 88 patients with treatment naive neovascular AMD, who were initially treated with three monthly IAIs, followed by monthly monitoring and re-injection as needed for at least 12 months. Subjects were classified into three groups according to the severity of the condition in their untreated eye, based on the severity scale in the Age-Related Eye Disease Study (AREDS): group 0, AREDS severity level 1 (no drusen); group 1, AREDS severity level 2 or 3 (any drusen); group 2, AREDS severity level 4 (advanced AMD). Genotyping was performed in all cases for ARMS2 A69S and CFH I62V. RESULTS: Fellow-eye severity was associated with age and the risk variant of ARMS2 A69S (P = 0.005 and 0.001, respectively). Although best-corrected visual acuity (BCVA) had improved significantly after 12 months in all groups, this improvement was significantly greater in group 0 than in the other groups (P = 0.008). The retreatment-free period was also significantly longer for group 0 than for the other groups (P = 0.016), and the number of additional injections was significantly associated with fellow-eye severity (P = 0.007). CONCLUSIONS: Fellow-eye severity was associated with treatment response in terms of visual improvement and retreatment and may be a predictive factor for response to IAI for neovascular AMD. PMID- 29177892 TI - Exploring the genetics of fertility restoration controlled by Rf1 in common wheat (Triticum aestivum L.) using high-density linkage maps. AB - Hybrid wheat breeding has the potential to significantly increase wheat productivity compared to line breeding. The induction of male sterility by the cytoplasm of Triticum timopheevii Zhuk. is a widely discussed approach to ensure cross-pollination between parental inbred lines in hybrid wheat seed production. As fertility restoration in hybrids with this cytoplasm is often incomplete, understanding the underlying genetics is a prerequisite to apply this technology. A promising component for fertility restoration is the restorer locus Rf1, which was first detected on chromosome 1A of the restorer accession R3. In the present study, we performed quantitative trait locus (QTL) analyses to locate Rf1 and estimate its effect in populations involving the restorer lines R3, R113 and L19. Molecular markers linked to Rf1 in these populations were used to analyse the genomic target region in T. timopheevii accessions and common wheat breeding lines. The QTL analyses revealed that Rf1 interacted with a modifier locus on chromosome 1BS and the restorer locus Rf4 on chromosome 6B. The modifier locus significantly influenced both the penetrance and expressivity of Rf1. Whereas Rf1 exhibited expressivity higher than that of Rf4, the effects of these loci were not additive. Evaluating the marker haplotype for the Rf1 region, we propose that the restoring Rf1 allele may be derived exclusively from T. timopheevii. The present study demonstrates that interactions between restorer and modifier loci play a critical role in fertility restoration of common wheat with the cytoplasm of T. timopheevii. PMID- 29177891 TI - Plasma levels of hypoxia-regulated factors in patients with age-related macular degeneration. AB - PURPOSE: Various hypoxia-related proteins are differentially expressed in the retina and secreted to the vitreous and/or aqueous humor of patients affected by dry or neovascular age-related macular degeneration (nAMD). To determine whether these conditions alter concentrations of cytokines also in the systemic circulation, we measured plasma levels of six hypoxia-related proteins. METHODS: Plasma was prepared from EDTA blood that was collected from patients affected by dry AMD (n = 5), nAMD (n = 11), proliferative diabetic retinopathy (PDR; n = 9), and patients with an epiretinal membrane (ERM; n = 11). ERM samples served as negative controls, PDR samples as positive controls. Protein concentrations of vascular endothelial growth factor (VEGF), erythropoietin (EPO), angiopoietin like 4 (ANGPTL4), placental growth factor (PlGF), tumor necrosis factor alpha (TNF-alpha), and pigment epithelium-derived factor (PEDF) were determined by enzyme-linked immunosorbent assay (ELISA). RESULTS: The concentration of PlGF was significantly increased in plasma of patients affected by nAMD. Although no statistically significant differences were found for EPO, ANGPTL4, PlGF, TNF alpha, and PEDF, the mean concentration of VEGF was lowest in the nAMD group. Plasma concentrations of the six factors did not correlate with gender or age of patients. CONCLUSIONS: nAMD may increase plasma concentrations of PlGF, making it a candidate as a biomarker for the neovascular form of AMD. Other factors, however, were not differentially regulated, suggesting that their systemic concentrations are not generally increased in hypoxia-related retinal diseases.

AB - Disturbances such as wildfire are important features of forested landscapes. The trajectory of changes following wildfires (often referred to as landscape recovery) continues to be an important research topic among ecologists and wildfire scientists. However, the landscape recovery process also has important social dimensions that may or may not correspond to ecological or biophysical perspectives. Perceptions of landscape recovery may affect people's attitudes and behaviors related to forest and wildfire management. We explored the variables that influence people's perceptions of landscape recovery across 25 fires that occurred in 2011 or 2012 in the United States of Washington, Oregon, Idaho, and Montana and that represented a range of fire behavior characteristics and landscape impacts. Residents near each of the 25 fires were randomly selected to receive questionnaires about their experiences with the nearby fire, including perceived impacts and how the landscape had recovered since the fire. People generally perceived landscapes as recovering, even though only one to two years had passed. Regression analysis suggested that perceptions of landscape recovery were positively related to stronger beliefs about the ecological role of fire and negatively related to loss of landscape attachment, concern about erosion, increasing distance from the fire perimeter, and longer lasting fires. Hierarchical linear modeling (HLM) analysis indicated that the above relationships were largely consistent across fires. These findings highlight that perceptions of post-fire landscape recovery are influenced by more than vegetation changes and include emotional and cognitive factors. We discuss the management implications of these findings. PMID- 29177895 TI - Biopsy diagnosis of colitis: an algorithmic approach. AB - Certain types of colitides, such as collagenous colitis, lymphocytic colitis, and ischemic colitis, have distinct histologic features that allow for a specific diagnosis. However, in most colonic biopsy specimens, a definite diagnosis cannot be established on the basis of histology alone. Thus, in most cases of colitis, it is helpful to utilize a systematic approach in order to recognize patterns of injury. This information in conjunction with clinical and laboratory findings may help pathologists narrow the differential diagnosis and/or establish a more definite etiology for the patient's illness in order to guide clinical management. We provide general guidelines to distinguish variations in normal mucosa and biopsy procedure-related artifacts from true inflammatory conditions. Inflammatory conditions may be further categorized into those with predominantly lymphoplasmacytic inflammation (with or without neutrophils), predominantly neutrophilic inflammation, predominantly eosinophilic inflammation, or paucicellular colitis, since each of these patterns of inflammation are associated with a distinct differential diagnosis. This review will focus on a pattern-based algorithmic approach to evaluating biopsies of patients who present to physicians with signs and symptoms of colitis.

AB - The original version of this article unfortunately contained a mistake. The name of the main component released by Nicrophorus defodiens in Fig. 1a should read "Fuscumyl acetate", not "Fuscumol". PMID- 29177897 TI - Attraction of Three Mirid Predators to Tomato Infested by Both the Tomato Leaf Mining Moth Tuta absoluta and the Whitefly Bemisia tabaci. AB - Plants emit volatile compounds in response to insect herbivory, which may play multiple roles as defensive compounds and mediators of interactions with other plants, microorganisms and animals. Herbivore-induced plant volatiles (HIPVs) may act as indirect plant defenses by attracting natural enemies of the attacking herbivore. We report here the first evidence of the attraction of three Neotropical mirid predators (Macrolophus basicornis, Engytatus varians and Campyloneuropsis infumatus) toward plants emitting volatiles induced upon feeding by two tomato pests, the leaf miner Tuta absoluta and the phloem feeder Bemisia tabaci, in olfactometer bioassays. Subsequently, we compared the composition of volatile blends emitted by insect-infested tomato plants by collecting headspace samples and analyzing them with GC-FID and GC-MS. Egg deposition by T. absoluta did not make tomato plants more attractive to the mirid predators than uninfested tomato plants. Macrolophus basicornis is attracted to tomato plants infested with either T. absoluta larvae or by a mixture of B. tabaci eggs, nymphs and adults. Engytatus varians and C. infumatus responded to volatile blends released by tomato plants infested with T. absoluta larvae over uninfested plants. Also, multiple herbivory by T. absoluta and B. tabaci did not increase the attraction of the mirids compared to infestation with T. absoluta alone. Terpenoids represented the most important class of compounds in the volatile blends and there were significant differences between the volatile blends emitted by tomato plants in response to attack by T. absoluta, B. tabaci, or by both insects. We, therefore, conclude that all three mirids use tomato plant volatiles to find T. absoluta larvae. Multiple herbivory did neither increase, nor decrease attraction of C. infumatus, E. varians and M. basicornis. By breeding for higher rates of emission of selected terpenes, increased attractiveness of tomato plants to natural enemies may improve the effectiveness of biological control. PMID- 29177898 TI - Adaptation of Defensive Strategies by the Pea Aphid Mediates Predation Risk from the Predatory Lady Beetle. AB - Within a species, individual animals adopt various defensive strategies to resist natural enemies, but the defensive strategies that are adopted in response to variations in predation risk are poorly understood. Here, we assessed consecutive foraging processes on cohorts of two biotypes (green and red) of the pea aphid, Acyrthosiphon pisum, by the predatory lady beetle Propylea japonica, to investigate the adaptive mechanism underlying the defensive strategy. We observed the behavioral responses of individuals (continue feeding or escape, i.e., walk away or drop off from initial feeding site), simultaneously quantified the amount of alarm pheromone, (E)-beta-farnesene (EbetaF) released from cohorts using gas chromatography-mass spectrometry (GC-MS), and recorded the foraging times of predators in intervals. The results indicated that: (1) the anti-predator responses differed markedly between biotypes and among the stages of the consecutive foraging processes. (2) Few green cohorts tended to release EbetaF during the first foraging; those that did released only a low dose that did not increase the number of escapes. However, the amount of EbetaF rose rapidly following the second foraging process, which caused an intense escape response. In contrast, more red cohorts released greater amounts of EbetaF, which caused more individuals to escape from their innate feeding sites during the first foraging. During the second foraging, more red individuals tended to escape without releasing EbetaF in greater quantities. (3) The foraging time was effectively shortened in each biotype cohort that adopted diverse defensive strategies. This study of the defensive strategies of the pea aphid may contribute to understanding the intraspecific differences in aphid defense mechanisms. PMID- 29177899 TI - Neuroprotective Effect of sigma1-Receptors on the Cell Model of Huntington's Disease. AB - Huntington's disease is a hereditary neurodegenerative disease that primarily affects striatal neurons. Recent studies demonstrated abnormalities in calcium regulation in striatal neurons in Huntington's disease, which leads to elimination of synaptic connections between cortical and striatal neurons. In the present study, we focused on the neuroprotective properties of sigma1-receptor, because one of its main functions is associated with modulation of calcium homeostasis in cells. The application of selective sigma1-receptor agonists to the corticostriatal cell culture restores synaptic connections between the cortical and striatal neurons. Based on the obtained data, we assume that sigma1 receptor is a promising target for the development of drugs for the therapy of Huntington's disease. PMID- 29177900 TI - Focal Unilateral Traumatic brain injury Causes Delayed Neurodegenerative Changes in the Brain of Rats. AB - A cascade of pathological changes in the intact hemisphere developed in rats 6 months after focal unilateral traumatic brain injury: neuronal degeneration, hyperexpression of alpha-synuclein, APP (beta-amyloid peptide precursor) protein, and glutamine synthetase in cells other than astrocytes. The development of these changes in the contralateral hemisphere indicated the emergence of extensive delayed neurodegenerative processes in the brain after traumatic brain injury, which were characteristic of diseases associated with pathological aging. PMID- 29177901 TI - Morphofunctional Properties of Human Platelets Treated with Silver Nanoparticles. AB - We studied structural and functional properties of human platelets in the presence of nanosilver particles. Incubation with 0.05-5 MUM silver nanoparticles suppressed platelet adhesion in a dose-dependent manner without affecting internal platelet structure; during adhesion, some granules were not exocytized. Spontaneous platelet activation was observed at nanoparticle concentrations 15 100 MUM. Addition of 1-5 MUM nanosilver to cells undergoing adhesion blocked massive platelet degranulation, but did not prevent the formation of lamellopodia. The maximum number of preserved granules in platelets was revealed in the presence of 2.5-5 MUM silver nanoparticles: 50% after platelet preincubation with silver nanoparticles and 75-77% after stabilization of adherent platelets with silver nanoparticles. PMID- 29177902 TI - Effect of Native and Modified Apolipoprotein A-I on DNA Synthesis in Cultures of Different Cells. AB - Culturing of bone marrow cells in serum-free RPMI-1640 medium for 24 h was accompanied by a decrease in the rate of [3H]-thymidine incorporation into DNA. Addition of native apolipoprotein A-I (apoA-I) or plasma LDL and HDL to the culture medium increased this parameter. In contrast to native apoA-I, its modified form decelerated DNA synthesis in bone marrow cells. A similar inhibitory effect of modified protein was observed in cultures of human embryonic kidney cells (HEK293) and in rapidly proliferating mouse macrophage cell line ANA 1. The only exclusion was human myeloid cell line U937: neither native nor modified apoA-I affected DNA synthesis in these cells. Thus, the regulatory effects of apoA-I are tissue-specific; this protein can produce either stimulatory or inhibitory effect on DNA biosynthesis in cells depending on its conformation. PMID- 29177903 TI - Comparison of Different Methods of Purification and Concentration in Production of Influenza Vaccine. AB - The overwhelming majority of influenza vaccines are prepared with the use of chicken embryo allantoic fluid. The presence of ovalbumin (this protein constitutes >60% total protein in the allantoic fluid) in the vaccine can lead to severe allergy. Hence, effective reduction of ovalbumin content is of crucial importance for vaccine production. We compared two methods of purification and concentration of influenza virus: zonal gradient ultracentrifugation and combined ultrafiltration/diafiltration and exclusion chromatography protocol, used for fabrication of seasonal vaccines. Combined chromatography is comparable with zonal centrifugation protocol by the results of ovalbumin removal (to meet standard requirements). PMID- 29177904 TI - Characteristics of Trophoblasts in Long-Term Culture. AB - We analyzed more than 40 cytotrophoblast cultures derived from cell islets that grew from trypsinized tissue fragments of placental microvilli. Phenotypic variability of trophoblasts was demonstrated. Changes in trophoblast morphology from epithelium-like or oval cells to bipolar and spindle-shaped or twisted and then to mesenchymal-like cells as well as intensive expression of cytokeratin-7 and vimentin attested to epithelial-mesenchymal transition of trophoblasts during in vitro culturing. Analysis of the expression of specific markers in long-term trophoblast culture (>=7 passages) revealed the possibility of culture contamination with other non-trophoblast cells including fibroblasts. High risk of trophoblast culture contamination with rapidly growing cells necessitates regular control of the cultures used in fundamental studies. Our experiments confirmed the possibility of long-term culturing of cells maintaining trophoblast properties. The identity and purity of 4 trophoblast cultures free from contamination and retaining the properties of pure culture during long-term (>10 passages) culturing in vitro were confirmed. PMID- 29177905 TI - Complex Analysis of Diffusion Transport and Microstructure of an Intervertebral Disk. AB - We studied the relationship between diffusion transport and morphological and microstructural organization of extracellular matrix of human intervertebral disk. Specimens of the lumbar intervertebral disks without abnormalities were studied ex vivo by diffusion-weighed magnetic resonance imaging, histological and immunohistochemical methods, and electron microscopy. Distribution of the diffusion coefficient in various compartments of the intervertebral disk was studied. Significant correlations between diffusion coefficient and cell density in the nucleus pulposus, posterior aspects of annulus fibrosus, and endplate at the level of the posterior annulus fibrosus were detected for each disk. In disks with nucleus pulposus diffusion coefficient below 15*10-4 mm2/sec, collagens X and XI were detected apart from aggrecan and collagens I and II. The results supplement the concept on the relationship between the microstructure and cell composition of various compartments of the intervertebral disk and parameters of nutrient transport. PMID- 29177906 TI - Experimental Study of Statistical Stability of Cardiointerval Samples. AB - In 1947 M. A. Bernstein proposed a hypothesis about "repetition without repetition" in biomechanics that was confirmed in psychophysiology by the Eskov Zinchenko effect. This effect can be applied to all parameters (except the parameters of the neuromuscular system) of human body homeostasis. For instance, this instability can be demonstrated for repeated samples of cardiointerval parameters (and other homeostasis parameters) of the human cardiorespiratory system. Within the framework of the new theory of chaos and self-organization, a method is proposed for calculation of matrices of paired comparisons of cardiointerval samples for assessing the physiological status of the human body and changes in homeostasis. Statistical instability of cardiointerval samples and their statistical distribution functions f(x) for successive cardiointerval samples in one subject is proven.

AB - Recombinant human bone morphogenetic protein-2 with an additional s-tag domain (s tag-BMP-2) synthesized in E. coli is characterized by higher solubility and activity than the protein without additional s-tag domain, which increases the yield during purification and simplifies protein introduction into the osteoplastic materials. The high osteoinductivity of the demineralized bone matrix with s-tag-BMP-2 was shown on the model of regeneration of cranial defects of a critical size in mice and on the model of implantation of porous titanium matrix into defects of femoral and tibial bones in rabbits. PMID- 29177908 TI - Formation of Tissue-Engineered Construct of Human Cartilage Tissue in a Flow Through Bioreactor. AB - We performed culturing of a cell-engineered construct of human cartilage tissue consisting of biopolymer microstructured collagen-containing hydrogel, human adipose tissue mesenchymal stromal cells, and induction chondrogenic culture medium in a specially designed flow-through bioreactor. On day 16 of the experiment, human adipose tissue mesenchymal stromal cells acquired flattened shape typical for chondroblasts, demonstrated high proliferative activity, and formed extracellular matrix. The observed histological changes in the cultured system attested to the beginning of the formation of a tissue-engineered construct of human cartilage tissue. PMID- 29177909 TI - Stem Cells and Progenitors in Human Peripheral Blood Get Activated by Extremely Active Resveratrol (XARTM). AB - Resveratrol generated enormous interest as it improved functions of multiple organs and could delay aging in animal models. However, basic mechanism of action was not understood and due to poor bioavailability, it has failed to enter the market. A highly active nano-formulation of resveratrol (XARTM) with enhanced bioavailability is now available. Present study was undertaken to evaluate its effects on stem cells biology in the human peripheral blood. Twelve healthy participants were enrolled of which five received XARTM, five were age-matched placebo controls and two were 76 and 85 years old. Peripheral blood was processed to study serum profile to monitor cardiac and pancreatic functions and subjected to density gradient centrifugation to enrich pluripotent (VSELs) and adult stem cells that get enriched along with red blood cells and in the Buffy coat respectively on Day 2 and Day 15 after XARTM treatment. The XARTM treatment resulted in an increased expression of pluripotency transcripts specific for VSELs (Oct-4A, Nanog and Sox2) on D2; specific transcripts for differentiation in the progenitors including Oct-4, Ikaros, CD14, CD90 on D15, and anti-ageing and tumor suppressor transcripts NAD, SIRT1, SIRT6 and p53 in both stem cells and progenitors. An improvement of cardiac and pancreatic markers in serum profile was also observed on D15. The decline in VSELs numbers with age and beneficial effects of the XARTM treatment were evident by up-regulation of specific transcripts and on serum profile. XARTM is a promising molecule that has the potential to activate pluripotent VSELs and tissue committed adult stem cells 'progenitors' resulting in the rejuvenation of various body tissues and for improved, cancer-free health with advanced age. PMID- 29177910 TI - Characteristic and Source of Atmospheric PM10- and PM2.5-bound PAHs in a Typical Metallurgic City Near Yangtze River in China. AB - The characteristics of atmospheric PM10- and PM2.5-bound polycyclic aromatic hydrocarbons (PAHs) were investigated in Tongling city, China. Results showed that the total concentrations of PM10- and PM2.5-bound PAHs exhibited distinct seasonal and spatial variability. The metallurgic sites showed the highest PAH concentrations, which is mainly attributed to the metallurgic activities (mainly copper ore smelting) and coal combustion as the smelting fuel. The rural area showed the lowest concentrations, but exhibited significant increase from summer to autumn. This seasonal fluctuation is mainly caused by the biomass burning at the sites in the harvest season. The diagnostic ratio indicated that the main PAHs sources were vehicle exhausts, coal combustion and biomass burning. The total BaP equivalent concentration (BAP-TEQ) was found to be maximum at DGS site in winter, whereas it was minimum at BGC site in summer. Risk assessment indicates that residential exposure to PAHs in the industrial area, especially in the winter season, may pose a greater inhalation cancer risk than people living in living area and rural area. PMID- 29177911 TI - Mechanisms of Sustained Neutrophilia in Patient WHIM-09, Cured of WHIM Syndrome by Chromothripsis. AB - WHIM-09 is the first patient described with WHIM syndrome, an autosomal dominant form of neutropenia related to bone marrow retention of neutrophils. Originally diagnosed incorrectly with autoimmune neutropenia, the patient underwent splenectomy at age 9, but the absolute neutrophil count (ANC) did not rise. Subsequently, she was spontaneously cured by chromothripsis (chromosome shattering), which deleted the disease allele CXCR4 R334X , and 163 other genes, on chromosome 2 in a single hematopoietic stem cell (HSC). Chromothriptic CXCR4 +/o HSCs replaced CXCR4 +/R334X WHIM HSCs, and the ANC rose to a new sustained and benign baseline ~ 2-3-fold above normal that had remained unexplained. Here, we show that splenectomized Cxcr4 +/o mice had sustained and benign neutrophilia, phenocopying neutrophilia in WHIM-09. In addition, WHIM-09's granulocyte macrophage precursor cells possessed increased granulocyte colony-forming activity ex vivo. Thus, WHIM-09's neutrophilia may be multifactorial, involving neutrophil-extrinsic factors (splenectomy), as well as CXCR4 haploinsufficiency dependent neutrophil-intrinsic factors (increased myeloid precursor cell differentiation). The strong bone marrow retention signal for neutrophils conferred by the WHIM mutation may have prevented neutrophilia after splenectomy until the mutation was deleted by chromothripsis.

PMID- 29177913 TI - Evaluation of the novel TSPO radiotracer [18F] VUIIS1008 in a preclinical model of cerebral ischemia in rats. AB - BACKGROUND: In vivo positron-emission tomography (PET) imaging of transporter protein (TSPO) expression is an attractive and indispensable tool for the diagnosis and therapy evaluation of neuroinflammation after cerebral ischemia. Despite several radiotracers have shown an excellent capacity to image neuroinflammation, novel radiotracers such as [18F] VUIIS1008 have shown promising properties to visualize and quantify the in vivo expression of TSPO. METHODS: Longitudinal in vivo magnetic resonance (MRI) and PET imaging studies with the novel TSPO radiotracer 2-(5,7-diethyl-2-(4-(2-[18F] fluoroethoxy) phenyl) pyrazolo [1,5-a] pyrimidin-3-yl)-N, N-diethylacetamide ([18F] VUIIS1008), and (N, N-diethyl-2-(2-[4-(2-fluoroethoxy)-phenyl]-5,7-dimethyl-pyrazolo [1,5-a] yrimidin-3-yl)-acetamide ([18F] DPA-714) were carried out before and at days 1, 3, 7, 14, 21, and 28 following the transient middle cerebral artery occlusion (MCAO) in rats. RESULTS: MRI images showed the extension and evolution of the brain infarction after ischemic stroke in rats. PET imaging with [18F] VUIIS1008 and [18F] DPA714 showed a progressive increase in the ischemic brain hemisphere during the first week, peaking at day 7 and followed by a decline from days 14 to 28 after cerebral ischemia. [18F] DPA714 uptake showed a mild uptake increase compared to [18F] VUIIS1008 in TSPO-rich ischemic brain regions. In vivo [18F] VUIIS1008 binding displacement with VUIIS1008 was more efficient than DPA714. Finally, immunohistochemistry confirmed a high expression of TSPO in microglial cells at day 7 after the MCAO in rats. CONCLUSIONS: Altogether, these results suggest that [18F] VUIIS1008 could become a valuable tool for the diagnosis and treatment evaluation of neuroinflammation following ischemic stroke. PMID- 29177915 TI - [Precancerous and early stage cancer of the bile duct system]. AB - Early stage cancer of the bile duct system is still difficult to diagnose. In cases of suspect lesions a stepwise diagnostic procedure consisting of computed tomography (CT), magnetic resonance imaging (MRI) with MR cholangiography (MRC) and possibly endoscopic retrograde cholangiopancreatography (ERCP) with brush cytology should immediately be carried out. If there is a sufficient suspicion for premalignancy or early stage cancer the indications for surgical intervention should clearly be defined. Only resection can lead to a decrease in the recurrence rate and a better long-term outcome. If the patient is in a functionally nonresectable condition the possibility of liver transplantation should be considered. PMID- 29177916 TI - Direct to consumer genetic testing-law and policy concerns in Ireland. AB - BACKGROUND: With rapid scientific and technological advances, the past few years has witnessed the emergence of a new genetic era and a growing understanding of the genetic make-up of human beings. These advances have propelled the introduction of companies offering direct to consumer (DTC) genetic testing, which facilitates the direct provision of such tests to consumers, (for example, via the internet). Although DTC genetic testing offers benefits by enhancing consumer accessibility to such technology, promoting proactive healthcare and increasing genetic awareness, it presents a myriad of challenges, from an ethical, legal and regulatory perspective. As DTC genetic testing usually eliminates the need for a medical professional in accessing genetic tests, this lack of professional guidance and counselling may result in misinterpretation and confusion regarding results. In addition, an evident concern relates to the scientific validity and quality of these tests. A further problem arising is the lack or inadequacy of regulation in this field. Despite the increasing accessibility of DTC genetic testing, this legislative vacuum is apparent in Ireland, where there is no concrete legislation. AIMS AND OBJECTIVES: This article explores the main ethical, legal and regulatory issues arising with the advent of rapid advances in DTC genetic testing in Ireland. Further, with inevitable future advances in genetic science, as well as increasing internet accessibility, the challenges presented are likely to become more amplified. CONCLUSIONS: In consideration of the ethical and legal challenges, this paper highlights the regulation of DTC genetic testing as a growing concern in Ireland, recognising its importance to both the scientific community as well as in respect of enhancing consumer confidence in such technologies. PMID- 29177918 TI - Disruptive Behavior Treatment Progress as a Function of Therapy Focus and Youth Diagnosis in a Community Mental Health Setting. AB - Monthly disruptive behavior treatment progress for 613 youth ages 7-18 receiving intensive in-home services was examined. Multilevel modeling indicated carrying a depressive mood diagnosis predicted less disruptive behavior progress compared to youth with only externalizing diagnoses. Paradoxically, more monthly focus on disruptive behavior treatment targets predicted lower concurrent progress ratings, while greater focus on depressive mood targets predicted greater disruptive behavior progress for youth with a depressive mood diagnosis. Findings held when other predictors of disruptive behavior progress were included as covariates, including episode length, youth age, and functional impairment. Treatment and research implications are discussed. PMID- 29177917 TI - MRI and multiple sclerosis--the evolving role of MRI in the diagnosis and management of MS: the radiologist's perspective. AB - Magnetic resonance imaging (MRI) plays an integral role in the management of multiple sclerosis (MS), from both diagnostic and therapeutic perspectives. This 2-part review aims to detail the evolving and expanding role of MRI for both radiologists and neurologists. In this article, we discuss the diagnostic criteria for MS relevant to radiologists, as well as its varying imaging manifestations. The role of MRI in therapeutic modification and complications are discussed. PMID- 29177919 TI - Entropy production in a fluid-solid system far from thermodynamic equilibrium. AB - The terminal orientation of a rigid body in a moving fluid is an example of a dissipative system, out of thermodynamic equilibrium and therefore a perfect testing ground for the validity of the maximum entropy production principle (MaxEP). Thus far, dynamical equations alone have been employed in studying the equilibrium states in fluid-solid interactions, but these are far too complex and become analytically intractable when inertial effects come into play. At that stage, our only recourse is to rely on numerical techniques which can be computationally expensive. In our past work, we have shown that the MaxEP is a reliable tool to help predict orientational equilibrium states of highly symmetric bodies such as cylinders, spheroids and toroidal bodies. The MaxEP correctly helps choose the stable equilibrium in these cases when the system is slightly out of thermodynamic equilibrium. In the current paper, we expand our analysis to examine i) bodies with fewer symmetries than previously reported, for instance, a half-ellipse and ii) when the system is far from thermodynamic equilibrium. Using two-dimensional numerical studies at Reynolds numbers ranging between 0 and 14, we examine the validity of the MaxEP. Our analysis of flow past a half-ellipse shows that overall the MaxEP is a good predictor of the equilibrium states but, in the special case of the half-ellipse with aspect ratio much greater than unity, the MaxEP is replaced by the Min-MaxEP, at higher Reynolds numbers when inertial effects come into play. Experiments in sedimentation tanks and with hinged bodies in a flow tank confirm these calculations. PMID- 29177920 TI - Examining the Durability of Colorectal Cancer Screening Awareness and Health Beliefs Among Medically Underserved Patients: Baseline to 12 months Post Intervention. AB - The current study examines changes in awareness and health beliefs from baseline to 12 months post-intervention following receipt of one of two colorectal cancer (CRC) educational interventions that aimed to promote CRC screening among a racially and ethnically diverse and medically underserved population. Participants (N = 270) were enrolled in a randomized controlled trial to increase CRC screening and completed both baseline and 12-month follow-up assessments. Participants were aged 50-75, at average CRC risk, not up-to-date with CRC screening guidelines, and receiving care at one of three community-based clinics. Participants were randomized to receive either a targeted, low-literacy intervention informed by the Preventive Health Model [PHM] (photonovella and DVD plus fecal immunochemical test [FIT]) or a non-targeted intervention (standard educational brochure plus FIT). Changes in CRC awareness and health beliefs from baseline to 12 months were examined both within and between intervention groups using Student's t tests. Participants in both intervention conditions demonstrated an increase in CRC awareness, PHM social influence, and trust in the healthcare system (all p's < .0001), with no significant between-group differences. Among those receiving the targeted intervention, there also was an increase in PHM salience (p < .05). Among individuals receiving the non-targeted intervention, there was an increase in PHM response efficacy (p < .01) and PHM self-efficacy (p < .0001). Both CRC screening interventions promoted positive changes in awareness and several health beliefs from baseline to 12 months, suggesting important benefits of CRC education. Regardless of whether education was targeted or non-targeted, providing CRC screening education successfully promoted durable changes in awareness and health beliefs. PMID- 29177921 TI - Inhibitory effects and related molecular mechanisms of total flavonoids in Mosla chinensis Maxim against H1N1 influenza virus. AB - OBJECTIVE: The Shixiangru (Mosla chinensis Maxim) total flavonoids (STF) mainly contain luteolin and apigenin. The study aims to examine the inhibitory effects of STF on anti-H1N1 influenza virus and its related molecular mechanisms in pneumonia mice. METHODS: The viral pneumonia mice were treated with Ribavirin or various doses of STF. We observed histological changes of lung by immunohistochemistry and measured lung index to value anti-influenza virus effects of STF. The concentrations of inflammatory cytokines and anti-oxidant factors were detected by ELISA. RT-PCR and western blot assays were used to determine the expression level of TLR pathway's key genes and proteins in lung tissues. RESULTS: We found that the pathological changes of lung in the viral pneumonia mice obviously alleviated by STF treatments and the STF (288 or 576 mg/kg) could significantly decrease lung indices. Moreover, the up-regulation (IL 6, TNF-alpha, IFN-gamma, and NO) and down-regulation (IL-2, SOD and GSH) of inflammatory cytokines and anti-oxidant factors were associated with higher clearance of virus and reduction of inflammatory lung tissue damage. Meanwhile, the expression levels of TLR3, TLR7, MyD88, TRAF3 and NF-kappaB p65 of the TLR pathway were reduced by STF treatment. CONCLUSIONS: This study suggested that STF may be a promising candidate for treating H1N1 influenza and subsequent viral pneumonia. PMID- 29177922 TI - SGLT1 and SGLT1 Inhibitors: A Role to Be Assessed in the Current Clinical Practice. AB - Diabetes is a complex disease of increasingly common occurrence worldwide. Attaining optimal glycemic control is the main challenge to prevent the development of diabetes-related complications and/or to stop their progression. In recent years, the pharmacologic toolkit for the treatment of diabetes has considerably expanded, thus paving the way to more pathophysiology-oriented therapies. For instance, the sodium-glucose cotransporters SGLT2 and SGLT1 have been in the spotlight because of better knowledge of their physiology and therapeutic potential. At present, whereas the SGLT2 inhibitors are widely applied in current clinical practice as an effective and well-tolerated treatment that increases the urinary excretion of glucose, less is known about the use of SGLT1 inhibitors. SGLT1s are of primary importance in the small intestine, an organ that does not express SGLT2, while in the kidney they are expressed in the late renal proximal tubules, where it reabsorbs the glucose escaped from the upstream SGLT2. Hence, SGLT1-mediated glucose reabsorption in the kidney is increased when the tubular glucose load overwhelms the capacity of SGLT2 or when the latter is inhibited. The role of SGLT1 in intestinal and renal glucose transport makes the transporter a potential target for antidiabetic therapy. Here, we briefly report the evidence on LX2761, a new inhibitor against SGLT1 and SGLT2 in vitro, which acts in vivo as a selective inhibitor of SGLT1 in the gastrointestinal tract. LX2761 improves glycemic control without the glycosuria related side effects of SGLT2 inhibitors, particularly genitourinary tract infections. However, whether it represents a valid therapeutic option for all patients with diabetes or is more appropriate for specific phenotypes, e.g., patients with concomitant diabetes and chronic kidney disease, who may benefit less from the renal mechanism of selective SGLT2 inhibitors, remains to be tested in large randomized controlled trials. PMID- 29177923 TI - Skin Autofluorescence is a Noninvasive Surrogate Marker for Diabetic Microvascular Complications and Carotid Intima-Media Thickness in Japanese Patients with Type 2 Diabetes: A Cross-sectional Study. AB - INTRODUCTION: Advanced glycation end-products (AGEs) are known to play an important role in the pathogenesis of diabetic complications. Skin autofluorescence (AF), a marker of AGE accumulation in tissue, can be measured noninvasively using a skin AF reader. The present study aimed to evaluate the relationships of skin AF with diabetic microvascular complications and carotid intima-media thickness (IMT), a surrogate marker for atherosclerosis, in Japanese subjects with type 2 diabetes (T2D). METHODS: One hundred sixty-two subjects with T2D and 42 nondiabetic control subjects attending the outpatient clinic were examined. Skin AF and carotid max-IMT were measured using an AGE ReaderTM and ultrasonography, respectively. Nephropathy was classified into five stages based on the urinary albumin-to-creatinine ratio (UACR) as follows: (1) pre-nephropathy (stage 1) (UACR < 30 mg/g Cr); (2) incipient nephropathy (stage 2) (30 <= UACR < 300 mg/g Cr); (3) overt nephropathy (stage 3) (UACR >= 300 mg/g Cr); (4) kidney failure (stage 4) (estimated glomerular filtration rate (eGFR) < 30 ml/min/1.732); and (5) dialysis therapy (stage 5). Patients with kidney failure and those receiving dialysis therapy were excluded because the sample size was too small. Retinopathy was diagnosed as nondiabetic retinopathy (NDR), nonproliferative retinopathy (NPDR), or proliferative retinopathy (PDR). Diabetic peripheral neuropathy (DPN) was diagnosed if two or more of the following were present: neuropathic symptoms (decreased sensation, positive neuropathic sensory symptoms), symmetric decreased distal sensation, and unequivocally decreased or absent ankle reflexes. RESULTS: Skin AF values were significantly higher in subjects with T2D (2.53 +/- 0.45 AU) than in nondiabetic subjects (2.19 +/- 0.34 AU, p < 0.001). Skin AF significantly increased with the severity of DPN (2.39 +/ 0.37 with DPN vs 2.80 +/- 0.48 without DPN, p < 0.001), retinopathy (NDR 2.42 +/ 0.45, mild and moderate NPDR 2.64 +/- 0.42, p = 0.042, severe NPDR and PDR 2.85 +/- 0.35, p < 0.001), and nephropathy (pre-nephropathy 2.42 +/- 0.44, incipient nephropathy 2.62 +/- 0.45, p = 0.049, overt nephropathy 2.59 +/- 0.46, p = 0.80). Skin AF was an independent determinant of the presence of DPN (OR 8.49, 95% CI 2.04-44.32, p = 0.006) and retinopathy (OR 3.73, 95% CI 1.20-12.90, p = 0.028) but not of diabetic nephropathy after correcting for confounding factors. In addition, skin AF (beta = 0.170, p = 0.029) was an independent determinant of max IMT, as was age (beta = 0.436, p < 0.0001), after adjusting for other risk factors. CONCLUSION: Skin AF as measured using an AGE Reader is a noninvasive surrogate marker for diabetic microvascular complications and early-stage atherosclerosis. PMID- 29177924 TI - The diagnostic accuracy of high b-value diffusion- and T2-weighted imaging for the detection of prostate cancer: a meta-analysis. AB - PURPOSE: This study aims to investigate the role of diffusion-weighted imaging (DWI) and T2-weighted imaging (T2WI) in combination for the detection of prostate cancer, specifically assessing the role of high b-values (> 1000 s/mm2), with a systematic review and meta-analysis of the existing published data. METHODS: The electronic databases MEDLINE, EMBASE, and OpenSIGLE were searched between inception and September 1, 2017. Eligible studies were those that reported the sensitivity and specificity of DWI and T2WI for the diagnosis of prostate cancer by visual assessment using a histopathologic reference standard. The QUADAS-2 critical appraisal tool was used to assess the quality of included studies. A meta-analysis with pooling of sensitivity, specificity, likelihood, and diagnostic odds ratios was undertaken, and a summary receiver-operating characteristics (sROC) curve was constructed. Predetermined subgroup analysis was also performed. RESULTS: Thirty-three studies were included in the final analysis, evaluating 2949 patients. The pooled sensitivity and specificity were 0.69 (95% CI 0.68-0.69) and 0.84 (95% CI 0.83-0.85), respectively, and the sROC AUC was 0.84 (95% CI 0.81-0.87). Subgroup analysis showed significantly better sensitivity with high b-values (> 1000 s/mm2). There was high statistical heterogeneity between studies. CONCLUSION: The diagnostic accuracy of combined DWI and T2WI is good with high b-values (> 1000 s/mm2) seeming to improve overall sensitivity while maintaining specificity. However, further large-scale studies specifically looking at b-value choice are required before a categorical recommendation can be made. PMID- 29177925 TI - Genetics of pancreatic cancer and implications for therapy. AB - Pancreatic cancer is a highly lethal disease with a dismal 5-year prognosis. Knowledge of its genetics may help in identifying new methods for patient screening, and cancer treatment. In this review, we will describe the most common mutations responsible for the genesis of pancreatic cancer and their impact on screening, patterns of disease progression, and therapy.

AB - PURPOSE: Clinician gestalt may hold unexplored information that can be capitalized upon to improve existing nomograms. The study objective was to evaluate physician ability to predict 2-year overall survival (OS) in resected pancreatic ductal adenocarcinoma (PDAC) patients based on pre-operative clinical characteristics and routine CT imaging. METHODS: Ten surgeons and two radiologists were provided with a clinical vignette (including age, gender, presenting symptoms, and pre-operative CA19-9 when available) and pre-operative CT scan for 20 resected PDAC patients and asked to predict the probability of each patient reaching 2-year OS. Receiver operating characteristic curves were used to assess agreement and to compare performance with an established institutional nomogram. RESULTS: Ten surgeons and 2 radiologists participated in this study. The area under the curve (AUC) for all physicians was 0.707 (95% CI 0.642-0.772). Attending physicians with > 5 years experience performed better than physicians with < 5 years of clinical experience since completion of post graduate training (AUC = 0.710, 95% CI [0.536-0.884] compared to AUC = 0.662, 95% CI [0.398-0.927]). Radiologists performed better than surgeons (AUC = 0.875, 95% CI [0.765-0.985] compared to AUC = 0.656, 95% CI [0.580-0.732]). All but one physician outperformed the clinical nomogram (AUC = 0.604). CONCLUSIONS: This pilot study demonstrated significant promise in the quantification of physician gestalt. While PDAC remains a difficult disease to prognosticate, physicians, particularly those with more clinical experience and radiologic expertise, are able to perform with higher accuracy than existing nomograms in predicting 2-year survival. PMID- 29177928 TI - The bottom line: MRI and CT findings of unusual rectal and perirectal pathology. AB - Although common nonspecific symptoms (i.e., rectal bleeding, pelvic pressure, and change in bowel habits) are associated with rectal cancer, occasionally these are related to a different underlying disease. Over the past few years, considerable progress has been made in imaging of the rectum. Specifically, new magnetic resonance techniques and capabilities provide impressive high-resolution assessment of the rectal wall and enable evaluation and characterization of the perirectal tissues. This paper reviews imaging findings of uncommon causes of rectal and perirectal pathology that may be clinically confounded with rectal cancer. Radiologists need to be aware of uncommon pathologies in this region in order to facilitate optimal management decisions. PMID- 29177929 TI - Structure and dynamics of mesophilic variants from the homing endonuclease I DmoI. AB - I-DmoI, from the hyperthermophilic archaeon Desulfurococcus mobilis, belongs to the LAGLIDADG homing endonuclease protein family. Its members are highly specific enzymes capable of recognizing long DNA target sequences, thus providing potential tools for genome manipulation. Working towards this particular application, many efforts have been made to generate mesophilic variants of I DmoI that function at lower temperatures than the wild-type. Here, we report a structural and computational analysis of two I-DmoI mesophilic mutants. Despite very limited structural variations between the crystal structures of these variants and the wild-type, a different dynamical behaviour near the cleavage sites is observed. In particular, both the dynamics of the water molecules and the protein perturbation effect on the cleavage site correlate well with the changes observed in the experimental enzymatic activity. PMID- 29177930 TI - Value of in vitro acoustic radiation force impulse application on uterine adenomyosis. AB - PURPOSE: Adenomyosis is the presence of endometrial glandular and stromal tissue in the myometrium. This phenomenon can be the cause of excessive bleeding and menstrual pain in premenopausal women. Diagnosis of adenomyosis may present difficulty with conventional methods such as ultrasound and magnetic resonance imaging. Frequently, diagnosis is accomplished retrospectively based on the hysterectomy specimen. MATERIALS AND METHODS: This is a prospective case control study done in vitro on 90 patients' hysterectomy specimens. Acoustic radiation force impulse (ARFI) and color elastography were used to determine the elasticity of hysterectomy specimens of patients undergoing indicated surgeries. Based on histopathological examinations, two groups were formed: a study group (n = 28 with adenomyosis) and a control group (n = 62-without adenomyosis). RESULTS: Elasticity measurements of tissue with adenomyosis were observed to be significantly higher than measurements of normal myometrial tissue (p < 0.01). Uterine fibroids were found to have higher values on ARFI study compared to normal myometrial tissues (p < 0.01). CONCLUSION: The findings lead to the conclusion that adenomyosis tissue is significantly softer than the normal myometrium. ARFI was found to be beneficial in differentiating myometrial tissue with adenomyosis from normal myometrial tissue. It was found to be feasible and beneficial to implement ARFI in daily gynecology practice for diagnosis of adenomyosis. PMID- 29177931 TI - Evaluating the interaction of a tracheobronchial stent in an ovine in-vivo model. AB - Tracheobronchial stents are used to restore patency to stenosed airways. However, these devices are associated with many complications such as stent migration, granulation tissue formation, mucous plugging and stent strut fracture. Of these, granulation tissue formation is the complication that most frequently requires costly secondary interventions. In this study a biomechanical lung modelling framework recently developed by the authors to capture the lung in-vivo stress state under physiological loading is employed in conjunction with ovine pre clinical stenting results and device experimental data to evaluate the effect of stent interaction on granulation tissue formation. Stenting is simulated using a validated model of a prototype covered laser-cut tracheobronchial stent in a semi specific biomechanical lung model, and physiological loading is performed. Two computational methods are then used to predict possible granulation tissue formation: the standard method which utilises the increase in maximum principal stress change, and a newly proposed method which compares the change in contact pressure over a respiratory cycle. These computational predictions of granulation tissue formation are then compared to pre-clinical stenting observations after a 6-week implantation period. Experimental results of the pre-clinical stent implantation showed signs of granulation tissue formation both proximally and distally, with a greater proximal reaction. The standard method failed to show a correlation with the experimental results. However, the contact change method showed an apparent correlation with granulation tissue formation. These results suggest that this new method could be used as a tool to improve future device designs. PMID- 29177932 TI - A computational algorithm to simulate disorganization of collagen network in injured articular cartilage. AB - Cartilage defects are a known risk factor for osteoarthritis. Estimation of structural changes in these defects could help us to identify high risk defects and thus to identify patients that are susceptible for the onset and progression of osteoarthritis. Here, we present an algorithm combined with computational modeling to simulate the disorganization of collagen fibril network in injured cartilage. Several potential triggers for collagen disorganization were tested in the algorithm following the assumption that disorganization is dependent on the mechanical stimulus of the tissue. We found that tensile tissue stimulus alone was unable to preserve collagen architecture in intact cartilage as collagen network reoriented throughout the cartilage thickness. However, when collagen reorientation was based on both tensile tissue stimulus and tensile collagen fibril strains or stresses, the collagen network architecture was preserved in intact cartilage. Using the same approach, substantial collagen reorientation was predicted locally near the cartilage defect and particularly at the cartilage bone interface. The developed algorithm was able to predict similar structural findings reported in the literature that are associated with experimentally observed remodeling in articular cartilage. The proposed algorithm, if further validated, could help to predict structural changes in articular cartilage following post-traumatic injury potentially advancing to impaired cartilage function. PMID- 29177933 TI - Modeling the effect of collagen fibril alignment on ligament mechanical behavior. AB - Ligament mechanical behavior is primarily regulated by fibrous networks of type I collagen. Although these fibrous networks are typically highly aligned, healthy and injured ligament can also exhibit disorganized collagen architecture. The objective of this study was to determine whether variations in the collagen fibril network between neighboring ligaments can predict observed differences in mechanical behavior. Ligament specimens from two regions of bovine fetlock joints, which either exhibited highly aligned or disorganized collagen fibril networks, were mechanically tested in uniaxial tension. Confocal microscopy and FiberFit software were used to quantify the collagen fibril dispersion and mean fibril orientation in the mechanically tested specimens. These two structural parameters served as inputs into an established hyperelastic constitutive model that accounts for a continuous distribution of planar fibril orientations. The ability of the model to predict differences in the mechanical behavior between neighboring ligaments was tested by (1) curve fitting the model parameters to the stress response of the ligament with highly aligned fibrils and then (2) using this model to predict the stress response of the ligament with disorganized fibrils by only changing the parameter values for fibril dispersion and mean fibril orientation. This study found that when using parameter values for fibril dispersion and mean fibril orientation based on confocal imaging data, the model strongly predicted the average stress response of ligaments with disorganized fibrils ([Formula: see text]); however, the model only successfully predicted the individual stress response of ligaments with disorganized fibrils in half the specimens tested. Model predictions became worse when parameters for fibril dispersion and mean fibril orientation were not based on confocal imaging data. These findings emphasize the importance of collagen fibril alignment in ligament mechanics and help advance a mechanistic understanding of fibrillar networks in healthy and injured ligament.

AB - The article "Industrial antifoam agents impair ethanol fermentation and induce stress responses in yeast cells" was originally published Online First without open access. After publication in volume 101, issue 22, page 8237-8248, the author decided to opt for Open Choice and to make the article an open access publication. PMID- 29177935 TI - Pool deconvolution approach for high-throughput gene mining from Bacillus thuringiensis. AB - Novel genes from Bacillus thuringiensis (Bt) are required for effective deployment in agriculture, human health, and forestry. In an improvement over conventional PCR-based screening, next generation sequencing (NGS) has been used for identification of new genes of potential interest from Bt strains, but cost becomes a constraint when several isolates are to be sequenced. We demonstrate the potential of a DNA pooling strategy known as pool deconvolution to identify commercially important toxin genes from 36 native Bt isolates. This strategy is divided into three steps: (a) DNA pooling, (b) short read sequence assembly followed by gene mining, and (c) host isolate identification. With this approach, we have identified insecticidal protein (ip) genes including nine three-domain (3D) cry genes, three cyt-type genes, three mtx genes (mosquitocidal toxin), and one bin and vip-type gene each. Three cry-type and three cyt-type genes were cloned, out of which, two cry-type genes, ip11 and ip13, were named as cry4Ca2 and cry52Ca1, respectively by the Bacillus thuringiensis nomenclature committee ( http://www.biols.susx.ac.uk/Home/Neil_Crickmore/BT/ ). Our results show that the pool deconvolution approach is well suited for high-throughput gene mining in bacteria. PMID- 29177936 TI - Is bacterial vaginosis a disease? AB - Bacterial vaginosis (BV) has been described as a disease, a disorder, a vaginal inflammation, an infection, a microbial dysbiosis, a condition, and in some women, a normal situation. In order to fit the definition of a disease, BV would have to be a disorder of function that produces specific signs or symptoms or affects the vagina in an aberrant way. Yet, there is little consistency in patients reporting signs and symptoms when BV is diagnosed, nor the appearance of aberrations to the vagina. If BV is not a disease, there are implications for its management and coverage of treatment costs, and for the conclusions drawn in a multitude of previous studies. It is time for BV to be redefined and for the various subsets to be given a separate terminology with specific methods of diagnosis and appropriate treatment and preventive strategies. PMID- 29177937 TI - Biosynthesis of 2-aminooctanoic acid and its use to terminally modify a lactoferricin B peptide derivative for improved antimicrobial activity. AB - Terminal modification of peptides is frequently used to improve their hydrophobicity. While N-terminal modification with fatty acids (lipidation) has been reported previously, C-terminal lipidation is limited as it requires the use of linkers. Here we report the use of a biocatalyst for the production of an unnatural fatty amino acid, (S)-2-aminooctanoic acid (2-AOA) with enantiomeric excess > 98% ee and the subsequent use of 2-AOA to modify and improve the activity of an antimicrobial peptide. A transaminase originating from Chromobacterium violaceum was employed with a conversion efficiency 52-80% depending on the ratio of amino group donor to acceptor. 2-AOA is a fatty acid with amino functionality, which allowed direct C- and N-terminal conjugation respectively to an antimicrobial peptide (AMP) derived from lactoferricin B. The antibacterial activity of the modified peptides was improved by up to 16-fold. Furthermore, minimal inhibitory concentrations (MIC) of C-terminally modified peptide were always lower than N-terminally conjugated peptides. The C-terminally modified peptide exhibited MIC values of 25 MUg/ml for Escherichia coli, 50 MUg/ml for Bacillus subtilis, 100 MUg/ml for Salmonella typhimurium, 200 MUg/ml for Pseudomonas aeruginosa and 400 MUg/ml for Staphylococcus aureus. The C terminally modified peptide was the only peptide tested that showed complete inhibition of growth of S. aureus. PMID- 29177938 TI - Stabilization of multimeric sucrose synthase from Acidithiobacillus caldus via immobilization and post-immobilization techniques for synthesis of UDP-glucose. AB - Sucrose synthases (SuSys) have been attracting great interest in recent years in industrial biocatalysis. They can be used for the cost-effective production of uridine 5'-diphosphate glucose (UDP-glucose) or its in situ recycling if coupled to glycosyltransferases on the production of glycosides in the food, pharmaceutical, nutraceutical, and cosmetic industry. In this study, the homotetrameric SuSy from Acidithiobacillus caldus (SuSyAc) was immobilized stabilized on agarose beads activated with either (i) glyoxyl groups, (ii) cyanogen bromide groups, or (iii) heterogeneously activated with both glyoxyl and positively charged amino groups. The multipoint covalent immobilization of SuSyAc on glyoxyl agarose at pH 10.0 under optimized conditions provided a significant stabilization factor at reaction conditions (pH 5.0 and 45 degrees C). However, this strategy did not stabilize the enzyme quaternary structure. Thus, a post immobilization technique using functionalized polymers, such as polyethyleneimine (PEI) and dextran-aldehyde (dexCHO), was applied to cross-link all enzyme subunits. The coating of the optimal SuSyAc immobilized glyoxyl agarose with a bilayer of 25 kDa PEI and 25 kDa dexCHO completely stabilized the quaternary structure of the enzyme. Accordingly, the combination of immobilization and post immobilization techniques led to a biocatalyst 340-fold more stable than the non cross-linked biocatalyst, preserving 60% of its initial activity. This biocatalyst produced 256 mM of UDP-glucose in a single batch, accumulating 1 M after five reaction cycles. Therefore, this immobilized enzyme can be of great interest as a biocatalyst to synthesize UDP-glucose. PMID- 29177939 TI - Development of a high-copy-number plasmid via adaptive laboratory evolution of Corynebacterium glutamicum. AB - Beyond its traditional role as an L-amino acid producer, Corynebacterium glutamicum has recently received significant attention regarding its use in the production of various biochemicals and recombinant proteins. However, despite these attributes, limitations in genetic tools are still hampering the engineering of C. glutamicum for use in more potential hosts. Here, we engineered a C. glutamicum via adaptive laboratory evolution to enhance the production of recombinant proteins. During the continuous cultivation, C. glutamicum producing enhanced green fluorescent proteins was screened using high-speed flow cytometer, and in the end, we successfully isolated an evolved strain with a fluorescence intensity 4.5-fold higher than that of the original strain. Extensive analysis of the evolved strain confirmed that the plasmid prepared from the evolved strain contains the nonsense mutation in the parB locus, which mutation contributed to increasing the copy number of plasmid by approximately 10-fold compared to that of the wild type. To validate the usefulness of the high-copy-number plasmid, we examined the secretory production of endoxylanase and the bioconversion of xylose to xylonate using xylonate dehydrogenase. In the fed-batch cultivation, the use of the high-copy-number plasmid led to 1.4-fold increase in the production of endoxylanase (~ 1.54 g/L in culture medium) without cell growth retardation comparing cultivation with cells harboring original plasmid. The expression of xylonate dehydrogenase in the high-copy-number plasmid also improved the bioconversion into xylonic acid by approximately 1.5-fold compared to the original plasmid. PMID- 29177940 TI - Functional analysis of the dehydratase domains of a PUFA synthase from Thraustochytrium in Escherichia coli. AB - Thraustochytrium sp. 26185, a unicellular marine protist, synthesizes docosahexaenoic acid, an omega-3 very long chain polyunsaturated fatty acid (VLC PUFAs), by a polyunsaturated fatty acid (PUFA) synthase comprising three large subunits with multiple catalytic dehydratase (DH) domains critical for introducing double bonds at the specific position of fatty acids. To investigate functions of these DH domains, one DH domain from subunit-A and two DH domains from subunit-C of the PUFA synthase were dissected and expressed as stand-alone enzymes in Escherichia coli. The results showed that all these DH domains could complement the defective phenotype of a E. coli FabA temperature sensitive mutant, despite they have only modest sequence similarity with FabA, indicating they can function as 3-hydroxyacyl-ACP dehydratase for the biosynthesis of unsaturated fatty acids in E. coli. Site-directed mutagenesis analysis confirmed the authenticity of active site residues in these domains. In addition, overexpression of the three domains in a wild type E. coli strain resulted in the substantial alteration of fatty acid profiles including productions and ratio of unsaturated to saturated fatty acids. A combination of evidences from sequence comparison, functional expression, and mutagenesis analysis suggest that the DH domain from subunit-A is similar to DH domains from polyketide synthases, while the DH domains from subunit-C are more comparable to E. coli FabA in catalytic functions. Successful complementation and functional expression of the embedded DH domains from the PUFA synthase in E. coli is an important step towards for elucidating the molecular mechanism in the biosynthesis of VLC-PUFAs in Thraustochytrium. PMID- 29177941 TI - Investigation of Acute and Chronic Toxicity Trends of Pesticides Using High Throughput Bioluminescence Assay Based on the Test Organism Vibrio fischeri. AB - High-throughput acute and chronic toxicity tests using Vibrio fischeri were used to assess the toxicity of a variety of fungicides, herbicides, and neonicotinoids. The use of time points beyond the traditional 30 min of an acute test highlighted the sensitivity and applicability of the chronic toxicity test and indicated that for some compounds toxicity is underestimated using only the acute test. The comparison of EC50 values obtained from acute and chronic tests provided insight regarding the toxicity mode of action, either being direct or indirect. Using a structure-activity relationship approach similar to the one used in hazard assessments, the relationship between toxicity and key physicochemical properties of pesticides was investigated and trends were identified. This study not only provides new information regarding acute toxicity of some pesticides but also is one of the first studies to investigate the chronic toxicity of pesticides using the test organism V. fischeri. The findings demonstrated that the initial bioluminescence has a large effect on the calculated effective concentrations for target compounds in both acute and chronic tests, providing a way to improve and standardize the test protocol. In addition, the findings emphasize the need for additional investigation regarding the relationship between a toxicant's physicochemical properties and mode of action in nontarget organisms. PMID- 29177942 TI - The net effects of medical malpractice tort reform on health insurance losses: the Texas experience. AB - In this paper, we examine the influence of medical malpractice tort reform on the level of private health insurance company losses incurred. We employ a natural experiment framework centered on a series of tort reform measures enacted in Texas in 2003 that drastically altered the medical malpractice environment in the state. The results of a difference-in-differences analysis using a variety of comparison states, as well as a difference-in-difference-in-differences analysis, indicate that ameliorating medical malpractice risk has little effect on health insurance losses incurred by private health insurers.

AB - PURPOSE: The differential effect of occupational and leisure time physical activity on cardiovascular health is termed the physical activity health paradox. Cardiac autonomic modulation could bring insights about the underlying mechanism behind this differential effect. The aim was to compare heart rate variability (HRV) during different activities (sitting, standing and moving) at work and leisure among blue-collar workers. METHODS: One hundred thirty-eight workers from the NOMAD cohort were included. Data from physical activity and HRV were obtained for 3-4 days using tri-axial accelerometers (Actigraph GT3X+) and a heart rate monitor (Actiheart). HRV indices were determined during sitting, standing and moving both at work and leisure. Linear mixed-models with two fixed factors (activities and domains) were applied to investigate differences in HRV indices adjusting for individual and occupational factors. RESULTS: The results showed significant effects of domain (p < 0.01), physical activity type (p < 0.01) and interaction between domain and activity type (p < 0.01) on HRV indices. Mean heart rate (IBI) and parasympathetic measures of HRV (RMSSD and HF) were lower for sitting (p < 0.01) and higher for moving (p < 0.01) during work compared with leisure, while no difference between domains was found for standing (p > 0.05). Sympathovagal balance (LF/HF) was higher during work for sitting and moving (p < 0.01), but showed no difference for standing (p = 0.62). CONCLUSIONS: Differences in cardiac autonomic modulation between work and leisure were found, indicating sympathetic predominance during work and parasympathetic predominance during leisure for sitting. Autonomic responses can be part of the mechanism that explains the differential effect of occupational and leisure time physical activity on health. PMID- 29177945 TI - Removing the urinary catheter on post-operative day 2 after robot-assisted laparoscopic radical prostatectomy: a feasibility study from a single high-volume referral centre. AB - The indwelling urinary catheter (UC) is a significant bother for men after radical prostatectomy (RP) and should be removed as soon as possible without jeopardizing the outcome. Our aim was to assess the feasibility and safety of its removal on postoperative day (POD) 2 after robot-assisted laparoscopic RP (RALP). A consecutive series of patients undergoing RALP for localized prostate cancer (PCa) were prospectively enrolled. Inclusion criteria were: no bladder-neck reconstruction, watertight urethrovesical anastomosis at 150 ml filling, <= 200 ml of intraoperative bleeding, <= 80 ml of fluid from the drain on POD 1, clear urine from the UC on POD 2. Patients were discharged on POD 2. Continence was assessed at catheter removal and 1, 3 and 6 months after surgery. Urethrovesical anastomosis was performed with a standard technique on 3 layers. Sixty-six patients were enrolled. The UC was removed on POD 2 in all the cases and 96.4% of the patients were discharged on POD 2. Re-catheterization was needed 16 times and it was always performed easily. Twenty-four complications were reported by 20 patients, mostly Clavien-Dindo (CD) grade II; 2 CD IIIB complications were observed. No anastomotic strictures were diagnosed. At catheter removal, 29% of the patients were completely continent, 41% at 1 month, 67% at 3 months and 92% at 6 months. In selected patients, removing the UC 48 h after RALP is feasible and safe and has no negative impact on continence if compared with the best international standards. PMID- 29177946 TI - Clinical outcomes after Ex-PRESS glaucoma shunt versus non-penetrating deep sclerectomy: two-year follow-up. AB - PURPOSE: To compare the two-year outcomes of non-penetrating deep sclerectomy (NPDS) and Ex-PRESS glaucoma shunt. METHODS: A retrospective chart review of patients who had undergone NPDS or Ex-PRESS since 2012 was conducted. Patients were excluded if they had undergone eye surgery other than cataract extraction, were diagnosed with ocular pathology other than glaucoma or had less than two year follow-up. Pre- and postoperative visual acuity, intraocular pressure (IOP), number of hypotensive drugs and visual fields were recorded, as well as intra- and postoperative complications. RESULTS: Thirty-nine eyes were included in the NPDS and twenty-three eyes in the Ex-PRESS group. There were no differences in baseline IOP and hypotensive drugs, IOP reduction or postoperative IOP-lowering medications between groups. Two years after surgery, IOP decrease compared to baseline was 23.5% with NPDS and 24.8% with Ex-PRESS. Qualified success (a 20% IOP reduction, with IOP <= 18 mmHg with or without medication) rates were similar: 53.8 and 69.6% for NPDS and Ex-PRESS. Visual fields progressed in four eyes of the NPDS (10.2%) and in three eyes (8.7%) of the Ex-PRESS group. As regards complications, early hypotony was more frequent after NPDS (9 eyes, 23.1%) than Ex-PRESS (2 eyes, 8.7%), although the difference was not statistically significant. CONCLUSIONS: Both NPDS and Ex-PRESS produce an IOP lowering effect of approximately 25%. Success rates are similar after both procedures, and both seem to lead to a stabilization of visual loss. PMID- 29177947 TI - Effect of Lactobacillus rhamnosus on the response of Galleria mellonella against Staphylococcus aureus and Escherichia coli infections. AB - This study evaluated the prophylactic effects of the live or heat-killed probiotic strain Lactobacillus rhamnosus ATCC 7469 in Galleria mellonella, inoculated with Staphylococcus aureus or Escherichia coli. L. rhamnosus suspension was prepared and a part of it was autoclaved to obtain heat-killed lactobacilli. The larvae were inoculated of these suspensions and pathogenic. The survival of the larvae was observed during 7 days and after 24 h of inoculation haemocytes counted, melanization and nitric oxide production were analyzed. Larvae survival rate increased in the group inoculated with heat-killed L. rhamnosus, however, with no statistical difference. There was a significant increase in total haemocyte counts in all test groups. Haemolymph melanization and nitric oxide production were higher in the group inoculated with L. rhamnosus and infected with S. aureus. It was concluded that, in this model of infection, heat-killed L. rhamnosus ATCC 7469 promoted greater protection in Galleria mellonella infected with S. aureus or E. coli. PMID- 29177948 TI - Increased serum amyloid A in nasal polyps is associated with systemic corticosteroid insensitivity in patients with chronic rhinosinusitis with nasal polyps: a pilot study. AB - BACKGROUND: Serum amyloid A (SAA) was involved in the pathogenesis of glucocorticoid resistance in lung diseases. However, their association with systemic corticosteroid insensitivity in chronic rhinosinusitis with nasal polyps (CRSwNP) patients remains to be assessed. METHODS: This study enrolled 32 CRSwNP patients to evaluate the association between SAA expression in NP and corticosteroid insensitivity, and the value of polyp SAA level for predicting the response to oral corticosteroids in CRSwNP patients. All patients were given a course of oral prednisone (30 mg daily for 2 weeks) and subdivided into glucocorticoid(GC)-sensitive and -insensitive subgroup according to the change in polyp size scores. The polyp specimens were obtained before and after corticosteroid treatment. SAA levels in polyp tissues were evaluated by enzyme linked immunosorbent assay and quantitative reverse transcription polymerase chain reaction. Regression analysis was performed to analyze the association between SAA protein levels and corticosteroid insensitivity. RESULTS: 13/32 (40.62%) CRSwNP patients were insensitive to the oral corticosteroid therapy. SAA mRNA and protein levels were significantly increased in GC-insensitive NP compared to those in GC-sensitive NP. Tissue SAA protein levels were positively correlated with tissue neutrophil numbers. Regression analysis revealed tissue SAA levels were significantly correlated with corticosteroid insensitivity (P < 0.01). ROC curves indicated that the area under the curve was 0.87. When the polyp SAA protein level was 122.2 ng/ml or higher, the sensitivity and specificity were 76.92 and 73.68%, respectively. CONCLUSIONS: Our findings suggest that increased SAA in NP is associated with reduced response to oral corticosteroids in CRSwNP. SAA levels in NP may have potential value in predicting corticosteroid insensitivity in CRSwNP patients.

AB - Quantitative susceptibility mapping (QSM) has been recently introduced as a novel MRI post-processing technique of gradient recalled echo (GRE) data. QSM is useful in depicting both brain anatomy and for detecting abnormalities. Its utility in the context of ischemic stroke has, however, not been extensively characterized so far. In this study, we explored the potential of QSM to characterize vascular and tissue changes in the transient middle cerebral artery occlusion (tMCAO) mouse model of cerebral ischemia. We acquired GRE data of mice brains at different time points after tMCAO, from which we computed QSM and MR frequency maps, and compared these maps with diffusion imaging and multi-slice multi-echo imaging data acquired in the same animals. Prominent vessels with increased magnetic susceptibility were visible surrounding the lesion on both frequency and magnetic susceptibility maps at all time points (mostly visible at > 12 h after reperfusion). Immunohistochemistry revealed the presence of compressed capillaries and dilated larger vessels, suggesting that the appearance of prominent vessels after reestablishment of reperfusion may serve compensatory purposes. In addition, on both contrast maps, tissue regions of decreased magnetic susceptibility were observed at 24 and 48 h after reperfusion that were distinctly different from the lesions seen on maps of the apparent diffusion coefficient and T 2 relaxation time constant. Since QSM can be extracted as an add-on from GRE data and thus requires no additional acquisition time in the course of acute stroke MRI examination, it may provide unique and complementary information during the course of acute stroke MRI examinations.

AB - PURPOSE: To investigate the appropriate mediolateral placement of symmetrical tibial components and the amount of overhang expected from the posterolateral of tibial components implanted to give ideal coverage and the subsequent incidence of residual knee pain and reduction in functional capacity. METHOD: A retrospective evaluation was made of 146 consecutive total knee arthroplasties. The posterolateral overhang, rotational alignment and coverage of the tibial component were measured on a post-operative CT scan and the effect of posterolateral overhang on clinical outcomes was analysed 3 years after surgery. RESULTS: Complaints of local pain in the posterolateral corner were determined in 76 (52.1%) patients. At the Posterolateral corner, overhang was determined in 111 (76%) patients, in the cortical border in 11 (7.6%) patients and underhang in 24 (16.4%) patients. In 71 (48.6%) patients, pain was determined together with oversize and in the evaluation of the overhang of the tibial component in the posterolateral region and the rotation status, there was determined to be overhang in 75 (96.2%) patients where the tibial component was placed in ideal rotation, in 25 (100%) where placement was in external rotation and in 11 (25.6%) where placement was in internal rotation. The mean KSS, KSS-F and WOMAC-P scores were 83.9 +/- 6.3, 83.3 +/- 7.8 and 4.6 +/- 2.9, respectively, in those with posterolateral overhang of the tibial component .The mean KSS, KSS-F and WOMAC-P scores were 86.6 +/- 8.4, 89.5 +/- 7.8 and 2.8 +/- 2.1, respectively, in those with no overhang and the difference was determined to be statistically significant. The amount of overhang was determined as mean 3.6 +/- 2.0 mm in those with posterolateral pain and 0.02 +/- 3.4 mm in those without pain and the difference was statistically significant. CONCLUSIONS: This study demonstrated that overhang in the posterolateral region is surprisingly high and negatively affects the clinical results following TKA, thereby presenting a danger to the success of TKA. The risk of posterolateral oversizing can increase with placement of the tibial component in external rotation. PMID- 29177949 TI - Prognostic value of CD45 transcriptional expression in head and neck cancer. AB - INTRODUCTION: Tumor-infiltrating lymphocytes (TILs) have a recognized antitumor activity in head and neck squamous cell carcinoma (HNSCC). CD45 is one of the most highly expressed proteins in lymphocytes. We carry out a study to assess the prognostic value of transcriptional expression of CD45 in HNSCC. MATERIAL AND METHODS: We determined the transcriptional expression of CD45 in 160 consecutive HNSCC patients and compared the TIL values according to the CD45 expression. RESULTS: Five-year disease-free survival for patients with a high transcriptional expression of CD45 (n = 107) was 62.4% and for patients with a low expression (n = 53) it was 36.2% (P = 0.003). Patients with a high expression of CD45 had a better local recurrence-free survival and disease-specific survival. The results of a multivariate analysis showed that patients with a low expression of CD45 had 2.0-fold high risk of recurrence (95% CI 1.2-3.2, P = 0.003). In oropharyngeal carcinomas, HPV-positive tumors showed a higher transcriptional CD45 expression than HPV-negative tumors. Tumors with high CD45 expression had immunohistochemical TIL scores significantly higher than those with low CD45 expression. CONCLUSION: According to our results, CD45 expression is a potential marker for tumor outcome in HNSCC patients. PMID- 29177952 TI - Distribution and phylogeny of Hyalomma ticks (Acari: Ixodidae) in Turkey. AB - The genus Hyalomma includes some of the most medically and veterinarily important tick species in the world. To clarify and identify the current distribution of the species of Hyalomma, field studies were conducted in 65 localities in Turkey and five localities in Cyprus. Additionally, using mitochondrial 12S and 16S ribosomal DNA, specimens of Hyalomma from Turkey, H. excavatum from Cyprus, H. marginatum from Spain and Italy were evaluated together with the available sequences obtained from Genbank. Morphological and molecular analyses demonstrated the presence of four species in Turkey: H. marginatum, H. excavatum, H. aegyptium and H. asiaticum. Hyalomma marginatum is the dominant species in the Central and Northern parts of Turkey, whereas H. excavatum distributes mostly in the Southern parts. Hyalomma asiaticum is restricted to the Southeastern Anatolia. However, some sympatric regions were observed for these species. Phylogenetic trees obtained with Maximum Likelihood method demonstrated five clades. Data supported previous conclusions, but placed H. asiaticum, H. scupense, H. dromedarii and H. aegyptium in different clades with high bootstrap values. Specimens of H. anatolicum group and H. marginatum complex are sister groups. Pairwise distance analyses of these groups showed 2.8 and 3% differences for 12S rDNA and 16S rDNA, respectively. Therefore, additional analyses with the samples from different locations using different markers need to evaluate the exact status of the species of these groups. PMID- 29177953 TI - Phase II Study of Gemcitabine Plus Sirolimus in Previously Treated Patients with Advanced Soft-Tissue Sarcoma: a Spanish Group for Research on Sarcomas (GEIS) Study. AB - BACKGROUND: Gemcitabine plus sirolimus enhances apoptosis in vitro and increases anti-tumor efficacy in vivo in soft-tissue sarcoma (STS) models. OBJECTIVE: The objective of this study was to evaluate the activity and toxicity of the combination of gemcitabine plus sirolimus in patients with STS after failure of standard chemotherapy. PATIENTS AND METHODS: Advanced STS patients, previously treated with doxorubicin and/or ifosfamide, were included in this single-arm phase II study. Patients received gemcitabine 800 mg/m2 intravenously (iv) at 10 mg/m2/min on days 1 and 8 every 3 weeks plus sirolimus 5 mg daily orally (po). After enrolment of the first 12 patients, the study protocol was amended due to toxicity and the starting dose of sirolimus was reduced to 3 mg daily po. Archival tumor samples were analyzed for extracellular signal-regulated kinase 1 and 2 (ERK1/2) expression and correlated with outcome. The primary endpoint was progression-free rate (PFR) at 3 months. RESULTS: From May 2012 to May 2013, 28 patients were enrolled at eight centers. PFR at 3 and 6 months was 44% and 20%, respectively, with 12 patients being free of progression at 3 months. Median progression-free survival (PFS) was 1.85 months (95% confidence interval [CI] 0.73-2.97) and median overall survival (OS) was 9.2 months (95% CI 5.8-12.5). No responses were observed. The most common grade 3-4 hematologic toxicities were neutropenia (48%) and leukopenia (41%) and the most frequent grade 3 non hematologic toxicities were infection (18.5%), transaminitis (15%), fatigue (11%), and pneumonitis (11%). ERK1/2 expression was significantly correlated with PFS (p = 0.026). CONCLUSIONS: The combination of gemcitabine and sirolimus is an active treatment in STS. Further investigation is warranted. ClinicalTrials.gov identifier: NCT01684449. PMID- 29177954 TI - Pharmacogenetic study of the impact of ABCB1 single-nucleotide polymorphisms on lenalidomide treatment outcomes in patients with multiple myeloma: results from a phase IV observational study and subsequent phase II clinical trial. AB - PURPOSE: Despite therapeutic advances, patients with multiple myeloma (MM) continue to experience disease relapse and treatment resistance. The gene ABCB1 encodes the drug transporter P-glycoprotein, which confers resistance through drug extrusion across the cell membrane. Lenalidomide (Len) is excreted mainly via the kidneys, and, given the expression of P-gp in the renal tubuli, single nucleotide polymorphisms (SNPs) in the ABCB1 gene may influence Len plasma concentrations and, subsequently, the outcome of treatment. We, therefore, investigated the influence of ABCB1 genetic variants on Len treatment outcomes and adverse events (AEs). METHODS: Ninety patients with relapsed or refractory MM, who received the second-line Len plus dexamethasone in the Rev II trial, were genotyped for the ABCB1 SNPs 1199G>A (Ser400Asn, rs2229109), 1236C>T (silent, rs1128503), 2677G>T/A (Ala893Ser, rs2032582), and 3435C>T (silent, rs1045642) using pyrosequencing, and correlations to response parameters, outcomes, and AEs were investigated. RESULTS: No significant associations were found between genotype and either best response rates or hematological AEs, and 1236C>T, 2677G>T or 3435C>T genotypes had no impact on survival. There was a trend towards increased time to progression (TTP) in patients carrying the 1199A variant, and a significant difference in TTP between genotypes in patients with standard-risk cytogenetics. CONCLUSIONS: Our findings show a limited influence of ABCB1 genotype on lenalidomide treatment efficacy and safety. The results suggest that 1199G>A may be a marker of TTP following Len treatment in standard-risk patients; however, larger studies are needed to validate and clarify the relationship. PMID- 29177955 TI - A randomized, double-blind, placebo-controlled, proof-of-concept trial of creatine monohydrate as adjunctive treatment for bipolar depression. AB - Depressive episodes are a major cause of morbidity and dysfunction in individuals suffering from bipolar disorder. Currently available treatments for this condition have limited efficacy and new therapeutic options are needed. Extensive research in the pathophysiology of bipolar disorder points to the existence of mitochondrial and bioenergetic dysfunction. We hypothesized that creatine monohydrate, a nutraceutical that works as a mitochondrial modulator, would be effective as an adjunctive therapy for bipolar depression. We conducted a double blind trial in which 35 patients with bipolar disorder type I or II in a depressive episode by DSM-IV criteria and in use of regular medication for the treatment of this phase of the disease were randomly allocated into two adjunctive treatment groups for 6 weeks: creatine monohydrate 6 g daily (N = 17) or placebo (N = 18). Primary efficacy was assessed by the change in the Montgomery-Asberg Depression Rating Scale (MADRS). We did not find a statistically significant difference in the comparison between groups for the change in score on the MADRS after 6 weeks in an intention-to-treat (ITT) analysis (p = 0.560; Cohen's d = 0.231). However, we found significant superiority of creatine add-on vs. placebo when we considered the remission criterion of a MADRS score <= 12 at week 6 analyzing the outcome of the 35 randomized patients on ITT (52.9% remission in the creatine group vs. 11.1% remission in the placebo group) and of the 23 completers (66.7% remission in the creatine group vs. 18.2% remission in the placebo group) (p = 0.012; OR = 9.0 and p = 0.036; OR = 9.0, respectively). Two patients who received creatine switched to hypomania/mania early in the trial. No clinically relevant physical side effects were reported or observed. This proof-of-concept study, aiming to restore brain bioenergetics using an adjunctive mitochondrial modulator, is not conclusive on the efficacy of creatine add-on for bipolar depression, but suggests that this compound may have a role in the adjunctive treatment of this phase of the illness. Further investigation through randomized controlled trials with larger samples should be conducted to verify the efficacy of creatine supplementation for bipolar depression and also for subsyndromal depressive symptoms. PMID- 29177956 TI - Urgency to Assess the Health Impact of Ambient Air Pollution in China. AB - As the world's second-largest economy, China is going on suffering from environmental pollution, especially for ambient air pollution, which has become a major threat to public health; public awareness of the detrimental effects of air pollution on health is increasing-particularly in relation to haze days. Considering the nonlinear relationship of ambient air pollution exposure and health impacts, and the differences in specific sources of air pollution with those in North America and Europe, conducting health impact assessments of ambient air pollution in China has thus become an urgent task for public health practitioners. Systematic review of the health effects of exposure to ambient air pollution from quantitative studies conducted in Chinese could provide vital information for epidemiology-based health impact assessments and the implementation of a national environmental protection policy. PMID- 29177957 TI - Characteristics of Major Air Pollutants in China. AB - Following the rapid development of China's economy, air pollution has become more and more serious. Air pollution in China presents complex pollution characterized by high PM2.5 and O3 concentration. This study presents an overview of the status of air quality and emission in China and discusses the temporal and spatial distribution of major pollutants (PM10, PM2.5, SO2, NOX, and O3). The results show that the reduced emissions have improved the air quality in China. However, the Chinese National Ambient Air Quality Standard (CNAAQS) for PM10 and PM2.5 still be exceeded in many cities of China in 2015. A total of 77.5% (for PM2.5) and 65.4% (for PM10) of the monitoring cities were found to be exceeded CNAAQS. The average annual O3 concentration was increasing during 2013-2015, and 16% of the total cities in 2015 did not meet the CNAAQS, indicating that O3 pollution should be paid more attention. For NO2 and SO2, the exceedances of CNAAQS are rare. PM2.5, PM10, and SO2 concentrations are higher in northern than in southern regions. High NO2 occurred in Beijing-Tianjin-Hebei and Yangtze River delta region. Secondary particles formation and motor vehicle exhaust were the main sources of PM2.5 in megacities. Dust was the main source for PM10. The formation of O3 is VOC-limited in urban areas of China and NOX-limited in nonurban areas. PMID- 29177958 TI - Human Exposure Assessment for Air Pollution. AB - Assessment of human exposure to air pollution is a fundamental part of the more general process of health risk assessment. The measurement methods for exposure assessment now include personal exposure monitoring, indoor-outdoor sampling, mobile monitoring, and exposure assessment modeling (such as proximity models, interpolation model, air dispersion models, and land-use regression (LUR) models). Among these methods, personal exposure measurement is considered to be the most accurate method of pollutant exposure assessment until now, since it can better quantify observed differences and better reflect exposure among smaller groups of people at ground level. And since the great differences of geographical environment, source distribution, pollution characteristics, economic conditions, and living habits, there is a wide range of differences between indoor, outdoor, and individual air pollution exposure in different regions of China. In general, the indoor particles in most Chinese families comprise infiltrated outdoor particles, particles generated indoors, and a few secondary organic aerosol particles, and in most cases, outdoor particle pollution concentrations are a major contributor to indoor concentrations in China. Furthermore, since the time, energy, and expense are limited, it is difficult to measure the concentration of pollutants for each individual. In recent years, obtaining the concentration of air pollutants by using a variety of exposure assessment models is becoming a main method which could solve the problem of the increasing number of individuals in epidemiology studies. PMID- 29177959 TI - Ambient Air Pollution and Biomarkers of Health Effect. AB - Recently, the air pollution situation of our country is very serious along with the development of urbanization and industrialization. Studies indicate that the exposure of air pollution can cause a rise of incidence and mortality of many diseases, such as chronic obstructive pulmonary disease (COPD), asthma, myocardial infarction, and so on. However, there is now growing evidence showing that significant air pollution exposures are associated with early biomarkers in various systems of the body. In order to better prevent and control the damage effect of air pollution, this article summarizes comprehensively epidemiological studies about the bad effects on the biomarkers of respiratory system, cardiovascular system, and genetic and epigenetic system exposure to ambient air pollution. PMID- 29177960 TI - Air Pollution and Mortality in China. AB - Ambient air pollution has been an important environmental issue in most areas of China. This chapter summarized the mortality effects of short-term and long-term exposures to various air pollutants among Chinese population. The literature review identified sufficient information to support significant short-term mortality effects of various air pollutants from time series analyses and case crossover studies, such as PM10, PM2.5, SO2, NO2, and O3. On the other hand, though the literature review suggested a positive effect of long-term exposure to air pollution on mortality and lung cancer risk, the evidence has been limited among Chinese population, indicating that more studies, especially cohort studies, are warranted. PMID- 29177961 TI - Ambient Air Pollution and Morbidity in Chinese. AB - The rapid economic growth in China is coupled with a severe ambient air pollution, which poses a huge threat to human health and the sustainable development of social economy. The rapid urbanization and industrialization over the last three decades have placed China as one of countries with the greatest disease burden in world. Notably, the prevalence rate of chronic noncommunicable diseases (CND), including respiratory diseases, CVD, and stroke, in 2010 reaches 16.9%. The continuous growth of the incidence of CND urgent needs for effective regulatory action for health protection. This study aims to evaluate the impact of rapid urbanization on status of ambient air pollution and associated adverse health effects on the incidence and the burden of CND and risk assessment. Our findings would be greatly significant in the prediction of the risk of ambient air pollution on CND and for evidence-based policy making and risk management in China. PMID- 29177962 TI - Air Pollution and Children's Health in Chinese. AB - Children can be considered as a high-risk population to environmental stress since some of the organ systems including the immune system and respiratory system are still in development during childhood. During childhood, the impact of environmental pollutants exposure may program child growth and development that have long-term consequences on later health and disease risk. Considering the rapid economic growth in recent decades in China, the impact of ambient air pollution on children health causes concerns. Therefore, we aimed to review the current epidemiological evidence on the effects of air pollution exposure on adverse health outcome, including respiratory diseases, lung function, high blood pressure, cognitive disorder, and obesity in childhood in China. We believe that the findings summarized in our review demonstrate an unequivocal relationship between air pollutants exposure and Chinese children health and these results have large public health influences. PMID- 29177963 TI - The Associations Between Air Pollution and Adverse Pregnancy Outcomes in China. AB - Research on the potential impact of air pollution on the human's health has increased rapidly in recent years. Several studies have suggested that exposure to air pollutants during period of pregnancy which is a crucial time point of mother-fetus development may have long-term and serious impact on adverse pregnancy outcomes. There is lack of review to evaluate the existed epidemiologic evidence on the associations between air pollutants and adverse pregnancy outcomes in China, so we conducted a review to explore the current epidemiological evidence on the effects of air pollutants to pregnancy outcomes and possible mechanisms during the pregnancy process. We used keywords to systematically search all the English and Chinese literatures on studies that were conducted in China. Exposure to air pollutants during pregnancy had shown there were harmful effects for different birth outcomes: preterm birth, low birth weight, stillbirth, birth defects, infertility, and macrosomia fetus. Results on the effects of air pollutants on adverse pregnancy outcomes are small and inconsistent because they vary in their design and methodology. The existed available evidence is compatible with either a small negative effect of air pollutants on pregnancy outcomes or with no effect; therefore, further studies are needed to confirm and quantify the possible associations and potential biologic mechanisms between air pollutants and pregnancy outcomes. PMID- 29177964 TI - Comparison of Health Impact of Air Pollution Between China and Other Countries. AB - Air pollution is the world's largest single environmental risk according to the World Health Organization (WHO), which caused around seven million deaths in 2012. Extensive epidemiological studies have been carried out worldwide to examine the health impacts of ambient air pollution, consistently demonstrating significant health impacts of ambient air pollution. Air pollution problem in China is especially serious; it has become the fourth biggest threat to the health of the Chinese people. In this review, we summarized existing literature, compared health impact of air pollution between China and other countries, and found substantial heterogeneity in the risk estimates of air pollution. The effect heterogeneities may be due to the differences in the characteristics of populations (e.g., the proportion of the elder population and people with preexisting diseases), exposure profile (e.g., air pollution concentrations and composition), and regional climate. Although the magnitude of relative risk estimates of air pollution is generally similar with that in other parts of the world, air pollution is one of China's most serious environmental health problems given the huge number of people exposed to high concentration levels of air pollution in China. PMID- 29177965 TI - Air Pollution, Disease Burden, and Health Economic Loss in China. AB - As the largest developing country in the world, China is now facing one of the severest air pollution problems. The objective of this section is to evaluate the disease burden and corresponding economic loss attributable to ambient air pollution in China. We reviewed a series of studies by Chinese or foreign investigators focusing on the disease burden and economic loss in China. These studies showed both the general air pollution and haze episodes have resulted in substantial disease burden in terms of excess number of premature deaths, disability-adjusted life-year loss, and years of life lost. The corresponding economic loss has accounted for an appreciable proportion of China's national economy. Overall, the disease burden and health economic loss due to ambient air pollution in China is greater than in the remaining parts of the world, for one of the highest levels of air pollution and the largest size of exposed population. Consideration of both health and economic impacts of air pollution can facilitate the Chinese government to develop environmental policies to reduce the emissions of various air pollutants and protect the public health. PMID- 29177966 TI - Air Pollution Prevention and Control Policy in China. AB - With rapid urbanization and development of transport infrastructure, air pollution caused by multiple-pollutant emissions and vehicle exhaust has been aggravated year by year in China. In order to improve air quality, the Chinese authorities have taken a series of actions to control air pollution emission load within a permissible range. However, although China has made positive progress on tackling air pollution, these actions have not kept up with its economy growth and fossil-fuel use. The traditional single-pollutant approach is far from enough in China now, and in the near future, air pollution control strategies should move in the direction of the multiple-pollutant approach. In addition, undesirable air quality is usually linked with the combination of high emissions and adverse weather conditions. However, few studies have been done on the influence of climate change on atmospheric chemistry in the global perspective. Available evidence suggested that climate change is likely to exacerbate certain kinds of air pollutants including ozone and smoke from wildfires. This has become a major public health problem because the interactions of global climate change, urban heat islands, and air pollution have adverse effects on human health. In this chapter, we first review the past and current circumstances of China's responses to air pollution. Then we discuss the control challenges and future options for a better air quality in China. Finally, we begin to unravel links between air pollution and climate change, providing new opportunities for integrated research and actions in China. PMID- 29177967 TI - Perspective for Future Research Direction About Health Impact of Ambient Air Pollution in China. AB - Air pollution has become one of the major risks to human health because of the progressive increase in the use of vehicles powered by fossil fuels. Although lots of works on the health impact of ambient air pollution have been done in China, the following recommendations for future research were identified in this chapter: (1) the synergistic effect of indoor air pollution with climate change; (2) develop new technologies to improve accurate assessment of air pollution exposure; (3) well-designed cohort study of sensitive populations including children, older people, and people with chronic health problems; (4) multi-omics technologies in the underlying mechanisms study; and (5) benefits evaluation of improvement of air quality. In conclusion, China is becoming a suitable study site, providing an ideal opportunity to evaluate the effects of environmental pollution, including air pollution, on human health, which might serve as an example for developing countries where health impacts of air pollution are as serious as in China. PMID- 29177968 TI - Microscopic characterization of orchid mycorrhizal fungi: Scleroderma as a putative novel orchid mycorrhizal fungus of Vanilla in different crop systems. AB - Vanilla is an orchid of economic importance widely cultivated in tropical regions and native to Mexico. We sampled three species of Vanilla (V. planifolia, V. pompona, and V. insignis) in different crop systems. We studied the effect of crop system on the abundance, type of fungi, and quality of pelotons found in the roots using light and electron microscopy and direct sequencing of mycorrhizal structures. Fungi were identified directly from pelotons obtained from terrestrial roots of vanilla plants in the flowering stage. Root samples were collected from plants in crop systems located in the Totonacapan area in Mexico (states of Puebla and Veracruz). DNA was extracted directly from 40 pelotons and amplified using ITS rRNA sequencing. Peloton-like structures were observed, presenting a combination of active pelotons characterized by abundant hyphal coils and pelotons in various stages of degradation. The most active pelotons were observed in crop systems throughout living tutors (host tree) in comparison with roots collected from dead or artificial tutors. Fungi identified directly from pelotons included Scleroderma areolatum, a common ectomycorrhizal fungus that has not been reported as a mycorrhizal symbiont in orchids. Direct amplification of pelotons also yielded common plant pathogens, including Fusarium and Pyrenophora seminiperda, especially in those sites with low colonization rates, and where large numbers of degraded pelotons were observed. This research reports for the first time the potential colonization of Vanilla by Scleroderma, as a putative orchid mycorrhizal symbiont in four sites in Mexico and the influence of crop system on mycorrhizal colonization on this orchid. PMID- 29177969 TI - The effect of methamphetamine exposure during pregnancy and lactation on hippocampal doublecortin expression, learning and memory of rat offspring. AB - The aim of this study was to evaluate the effect of methamphetamine (MA) exposure during pregnancy and lactation on doublecortin (DCX) expression in the hippocampus of rat offspring and also on learning/memory. Thirty-five pregnant Wistar rats were randomly divided into seven groups of 5 rats each: three experimental groups, each receiving 5 mg/kg body weight (BW) intraperitoneal (i.p.) injections of MA during pregnancy or/and lactation; three sham groups, each receiving saline injections; one control group, receiving no injection. After the interventions, two male pups (1 and 22 days old) were randomly selected from each mother, sacrificed and their brains subjected to DCX immunohistochemistry. One additional male pup from each mother was randomly selected and maintained for 60 days for testing in the Morris water maze and passive avoidance tests. MA administration during pregnancy was found to have significantly decreased the number of DCX-positive cells in the CA1, CA3 and DG regions of the hippocampus in the 1-day pups (P <= 0.05) and to have significantly decreased the number of DCX-positive cells in only two regions of the hippocampus, the CA1 and DG regions, in 22-day old pups. In comparison, exposure to MA during lactation was only associated with a significant decrease in the number of DCX-positive cells in the DG. Exposure to MA during pregnancy had significant impact on the intensity of DCX expression in the hippocampus of 1 and 22-day pups (P <= 0.05). There was no significant difference in memory/learning among the study groups. Our results indicate the administration of MA during pregnancy had a greater effect that during the lactation period on DCX expression in the hippocampus of rat offspring. PMID- 29177971 TI - Organic Ion Transporters and Statin Drug Interactions. AB - PURPOSE OF REVIEW: Statin drug-drug interactions (DDIs) are both troublesome to patients as well as costly to medical resources. The ability to predict and avoid these events could lead to improved outcomes as well as patient satisfaction. This review will explore efforts to better understand and predict these interactions specifically related to one drug transport system, the organic anion transporting polypeptides (OATPs) specifically OATP1B1 and OATP1B3. RECENT FINDINGS: Since the publication of the discovery of OATPs, there have been various pharmacokinetic models that have been proposed to explain the variation in pharmacokinetic and clinical effects related to the OATPs. The effects in transport activity appear to be partially related to the individual polymorphisms studied. Drug-drug interactions can occur when other drugs compete for the metabolic site on the OATPs. Various medications are identified as substrates and/or inhibitors of the OATPs, thereby complicating the ability to fully predict the impact on levels and effects. All of the models reviewed claim successes but show limited clinical utility. There are specific populations that have been identified, predominately various Asian descendants that require lower doses of statins to avoid adverse events. The concept of attributing these actions to the OATPs has been explored, but current models cannot accurately predict statin blood levels or elimination constants. The current research only points to the differences in the human genome and the single-nucleotide polymorphisms that exist between us. Based upon the currently available studies, there is beginning to be a glimmer in the understanding how different populations respond to statin transport and elimination. Additionally and unfortunately, there are other enzymes to be studied to better predict patient differences. Clearly, there has been much work completed, yet many more questions require answering to better understand these transport proteins. PMID- 29177970 TI - Feeding on different attractive flowering plants affects the energy reserves of Culex pipiens pallens adults. AB - Mosquito adults usually need to ingest sugar from nectar host plants to sustain their metabolic needs. Mosquitoes could be differentially attracted by various flowering plant species, and the volatiles were thought to be important factors attributed to the differential attractiveness. However, whether mosquitoes' preference for host plants correlates with their nutritional rewards from sugar sources remains unclear. In the present study, the preference of newly emerged Culex pipiens pallens to three kinds of flowering plants (Ligustrum quihoui, Abelia chinensis, and Nerium indicum) was determined in the olfactometer. Besides, when the newly emerged mosquitoes were provided with these flowering plants as sugar sources, the content of their metabolic reserves (glycogen, lipid, and protein) was determined. The results revealed that Cx. pipiens pallens could be differentially attracted by the odors emitted by the inflorescences of the tested flowering plants, and the nutritional rewards of mosquitoes were significantly affected by feeding on different inflorescences. The present study demonstrated that feeding on nectar host plants with differential attraction could affect the energy reserves of Cx. pipiens pallens. PMID- 29177972 TI - Conservation of the Enzyme-Coenzyme Interfaces in FAD and NADP Binding Adrenodoxin Reductase-A Ubiquitous Enzyme. AB - FAD and NAD(P) together represent an ideal pair for coupled redox reactions in their capacity to accept two electrons and their redox potentials. Enzymes that bind both NAD(P) and FAD represent large superfamilies that fulfill essential roles in numerous metabolic pathways. Adrenodoxin reductase (AdxR) shares Rossmann fold features with some of these superfamilies but remains in a group of its own in the absence of sequence homology. This article documents the phylogenetic distribution of AdxR by examining whole genome databases for Metazoa, Plantae, Fungi, and Protista, and determines the conserved structural features of AdxR. Scanning these databases showed that most organisms have a single gene coding for an AdxR ortholog. The sequence identity between AdxR orthologs is correlated with the phylogenetic distance among metazoan species. The NADP binding site of all AdxR orthologs showed a modified Rossmann fold motif with a GxGxxA consensus instead of the classical GxGxxG at the edge of the first betaalpha-fold. To examine the hypothesis that enzyme-coenzyme interfaces represent the conserved regions of AdxR, the residues interfacing FAD and NADP were identified and compared with multiple-sequence alignment results. Most conserved residues were indeed found at sites that surround the interfacing residues between the enzyme and the two coenzymes. In contrast to protein-protein interaction hot-spots that may appear in isolated patches, in AdxR the conserved regions show strict preservation of the overall structure. This structure maintains the precise positioning of the two coenzymes for optimal electron transfer between NADP and FAD without electron leakage to other acceptors.

AB - Purpose Raloxifene (RA) receptors have over-expressed GPER-positive breast cancer tumors. The purpose of this work was to evaluate the antitumor activity and pharmacokinetic behavior of docetaxel (DTX), loaded in RA-targeted nanomicelles, which were designed to overcome a lack of specific distribution and inadequate DTX concentration in tumor tissues, as well as its cytotoxicity and damage to normal tissues. Methods DTX-loaded RA-targeted poly(styrene maleic acid) (SMA)- poly(amide-ether-esterimide)-poly(ethylene glycol) (PAEEI-PEG) nanomicelles were prepared; then, their antitumor activity and survival rate were studied in MC4-L2 tumors induced in BALB/c mice. The pharmacokinetics of DTX-loaded SMA-PAEEI-PEG RA micelles was also investigated in comparison with free DTX. Results DTX-loaded SMA-PAEEI-PEG-RA micelles inhibited tumor growth considerably and increased animal survival as compared to free DTX and non-targeted micelles. SMA-PAEEIPEG RA micelles enhanced significantly the area under the curve (AUC0-infinity) 1.3 times as compared to free DTX and reduced clearance (CL) from 410.43 ml/kg.h (for free DTX) to 308.8 ml/kg.h (for SMA-PAEEI-PEG-RA micelles). Volume of distribution (Vdss) was also reduced 1.4 times as compared to free DTX. RA targeted micelles increased tumor inhibition rate (TIR) 1.3 times and median survival time (MST) >1.5 times compared to free DTX. Percentage increase in life span (%ILS) was also enhanced significantly from 41.66% to >83.33% in MC4-L2 tumor-bearing BALB/c mice. Discussion All studies in this work showed the potential of DTX-loaded SMA-PAEEI-PEG-RA micelles in the treatment of GPER positive receptor breast cancer tumors.

AB - ATP synthase is a complex universal enzyme responsible for ATP synthesis across all kingdoms of life. The F-type ATP synthase has been suggested to have evolved from two functionally independent, catalytic (F1) and membrane bound (Fo), ancestral modules. While the modular evolution of the synthase is supported by studies indicating independent assembly of the two subunits, the presence of intermediate assembly products suggests a more complex evolutionary process. We analyzed the phylogenetic profiles of the human mitochondrial proteins and bacterial transcription units to gain additional insight into the evolution of the F-type ATP synthase complex. In this study, we report the presence of intermediary modules based on the phylogenetic profiles of the human mitochondrial proteins. The two main intermediary modules comprise the alpha3beta3 hexamer in the F1 and the c-subunit ring in the Fo. A comprehensive analysis of bacterial transcription units of F1Fo ATP synthase revealed that while a long and constant order of F1Fo ATP synthase genes exists in a majority of bacterial genomes, highly conserved combinations of separate transcription units are present among certain bacterial classes and phyla. Based on our findings, we propose a model that includes the involvement of multiple modules in the evolution of F1Fo ATP synthase. The central and peripheral stalk subunits provide a link for the integration of the F1/Fo modules.

AB - Purpose Trabectedin is metabolized by the liver and has been associated with transient, noncumulative transaminase elevation. Two recent studies further characterize hepatic tolerability with trabectedin therapy: a phase 1 pharmacokinetic study (Study #1004; NCT01273493) in patients with advanced malignancies and hepatic impairment (HI), and a phase 3 study (Study #3007; NCT01343277) of trabectedin vs. dacarbazine in patients with advanced sarcomas and normal hepatic function. Methods In Study #1004, patients received a single 3 h intravenous (IV) infusion of trabectedin: control group, trabectedin 1.3 mg/m2; HI group (baseline total bilirubin >1.5 and <=3* upper limit of normal [ULN]; AST and ALT <=2.5* ULN), trabectedin 0.58 or 0.9 mg/m2. In Study #3007, the trabectedin group received 1.5 mg/m2 by 24-h IV infusion every 3 weeks until disease progression or unacceptable toxicity. Results In Study #1004, dose normalized trabectedin exposure was higher in HI patients (n = 6) versus controls (n = 9) (geometric mean ratios [90% CI] AUClast: 1.97 [1.20; 3.22]). In Study #3007, following trabectedin administration, 90% of patients had elevated ALT (32% grade 3-4) and 84% had elevated AST (17% grade 3-4). Transaminase elevations were transient and noncumulative. Progression-free survival was similar in patients with grade 3-4 hepatotoxicity (n = 109) versus grade 0-2 hepatotoxicity (n = 231) (median [95% CI]: 4.63 [4.01, 5.85] months versus 3.55 [2.73, 4.63] months; P = 0.545, HR = 0.91 [0.68-1.23]). Conclusion Trabectedin treatment of patients with HI results in higher plasma exposures. Hepatotoxicity in patients with normal liver function can be effectively addressed through dose reductions and delays. PMID- 29177976 TI - Probability of misclassifying biological elements in surface waters. AB - Measurement uncertainties are inherent to assessment of biological indices of water bodies. The effect of these uncertainties on the probability of misclassification of ecological status is the subject of this paper. Four Monte Carlo (M-C) models were applied to simulate the occurrence of random errors in the measurements of metrics corresponding to four biological elements of surface waters: macrophytes, phytoplankton, phytobenthos, and benthic macroinvertebrates. Long series of error-prone measurement values of these metrics, generated by M-C models, were used to identify cases in which values of any of the four biological indices lay outside of the "true" water body class, i.e., outside the class assigned from the actual physical measurements. Fraction of such cases in the M-C generated series was used to estimate the probability of misclassification. The method is particularly useful for estimating the probability of misclassification of the ecological status of surface water bodies in the case of short sequences of measurements of biological indices. The results of the Monte-Carlo simulations show a relatively high sensitivity of this probability to measurement errors of the river macrophyte index (MIR) and high robustness to measurement errors of the benthic macroinvertebrate index (MMI). The proposed method of using Monte-Carlo models to estimate the probability of misclassification has significant potential for assessing the uncertainty of water body status reported to the EC by the EU member countries according to WFD. The method can be readily applied also in risk assessment of water management decisions before adopting the status dependent corrective actions. PMID- 29177977 TI - Muscle Oximetry in Sports Science: A Systematic Review. AB - BACKGROUND: Since the introduction (in 2006) of commercially available portable wireless muscle oximeters, the use of muscle near-infrared spectroscopy (NIRS) technology is gaining in popularity as an application to observe changes in muscle metabolism and muscle oxygenation during and after exercise or training interventions in both laboratory and applied sports settings. OBJECTIVES: The objectives of this systematic review were to highlight the application of muscle oximetry in evaluating oxidative skeletal muscle performance to sport activities and emphasize how this technology has been applied to exercise and training. METHODS: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed in a systematic fashion to search, assess and synthesize existing literature on this topic. The Scopus and MEDLINE/PubMed electronic databases were searched to 1 March 2017. Potential inclusions were screened against eligibility criteria relating to recreationally trained to elite athletes, with or without training programs, who must have assessed physiological variables monitored by commercial oximeters or NIRS instrumentation. RESULTS: Of the 14,609 identified records, only 57 studies met the eligibility criteria. This systematic review highlighted a number of key findings in 16 sporting activities. Overall, NIRS information can be used as a marker of skeletal muscle oxidative capacity and for analyzing muscle performance factors. CONCLUSIONS: Although NIRS instrumentation is promising in evaluating oxidative skeletal muscle performance when used in sport settings, there is still the need for further instrumental development and randomized/longitudinal trials to support the detailed advantages of muscle oximetry utilization in sports science. PMID- 29177979 TI - Photobiomodulation effect on children's scars. AB - The management of burn scars has become one of the major clinical challenges in the developing countries which involve enormous treatment cost; this needs new methods for better cost benefit relationship. The objective of the study is to analyze the effectiveness of low-level laser therapy on post-burn scar tissue in children. A randomized controlled study included 15 children, ranging from 2 to 10 years of age, presenting with burn scars. They received diode laser and topical treatment. Each scar was divided into two halves. One half was treated with laser therapy and topical treatment (study area), and the other half was treated with topical treatment only (control area). The children were evaluated before and after 3 months of the study by Vancouver Scar Scale (VSS), ultrasonography (U/S), and laser Doppler perfusion imaging. Significant improvement was reported in the studied area compared to the control area for patients with P values (P = 0.005) and (P = 0.0001) for VSS and U/S scores, respectively. No difference was detected for blood perfusion to the scar between both areas (P = 0.18). In addition, no adverse effect was reported. Photobiomodulation is an efficient and safe therapeutic modality for post-burn hypertrophic scars in children and should be considered a part of combination therapy for better results. PMID- 29177978 TI - Zinc deficiency as a mediator of toxic effects of alcohol abuse. AB - OBJECTIVE: To review data on the role of ethanol-induced alteration of Zn homeostasis in mediation of adverse effects of alcohol abuse. METHODS: The scholarly published articles on the association between Zn metabolism and alcohol associated disorders (liver, brain, lung, gut dysfunction, and fetal alcohol syndrome) have been reviewed. RESULTS: It is demonstrated that alcohol-induced modulation of zinc transporters results in decreased Zn levels in lungs, liver, gut, and brain. Zn deficiency in the gut results in increased gut permeability, ultimately leading to endotoxemia and systemic inflammation. Similarly, Zn deficiency in lung epithelia and alveolar macrophages decreases lung barrier function resulting in respiratory distress syndrome. In turn, increased endotoxemia significantly contributes to proinflammatory state in alcoholic liver disease. Finally, impaired gut and liver functions may play a significant role in alcoholic brain damage, being associated with both increased proinflammatory signaling and accumulation of neurotoxic metabolites. It is also hypothesized that ethanol-induced Zn deficiency may interfere with neurotransmission. Similar changes may take place in the fetus as a result of impaired placental zinc transfer, maternal zinc deficiency, or maternal Zn sequestration, resulting in fetal alcoholic syndrome. Therefore, alcoholic Zn deficiency not only mediates the adverse effects of ethanol exposure, but also provides an additional link between different alcohol-induced disorders. CONCLUSIONS: Generally, current findings suggest that assessment of Zn status could be used as a diagnostic marker of metabolic disturbances in alcohol abuse, whereas modulation of Zn metabolism may be a potential tool in the treatment of alcohol-associated disorders. PMID- 29177980 TI - Cardiac autonomic responses and number of repetitions maximum after LED irradiation in the ipsilateral and contralateral lower limb. AB - The aim of this study was to verify the maximum number of repetitions, fatigue index, blood lactate concentration ([Lac]), and cardiac autonomic responses after LED irradiation (LEDI) in the ipsilateral and contralateral limb. Twelve male subjects (22.0 +/- 3.86 years; weight 82.94 +/- 12.58 kg; height 1.77 +/- 0.05 m), physically active, took part in this study. The subjects underwent a one repetition maximum (1RM) test and performed four randomly experimental sessions in the horizontal leg press exercise, which consisted in four sets of maximum repetitions at 80% of 1RM. The subjects performed two experimental sessions applying LED active or placebo on ipsilateral limb and two experimental sessions applying LED active or placebo on contralateral limb prior exercise and in the interval of sets on quadriceps and hamstrings muscles. A number of repetitions and fatigue index were verified. [Lac] and heart rate variability (HRV) were collected during post-exercise recovery and analyzed. It was observed that active LEDI promoted an increase in maximal number of repetitions (LEDI = 44.4 +/- 9.0 vs placebo = 39.9 +/- 11.4; p < 0.05) and decreases the fatigue index (LEDI = 34.3 +/- 21.8% vs placebo = 50.0 +/- 26.6%; p < 0.05) comparing to placebo situation, only in the ipsilateral application. There were no differences on [Lac] and in HRV parameters comparing LEDI vs placebo on post-exercise recovery in both applications (p > 0.05). The LEDI improves performance only in the ipsilateral application, but there were no differences on [Lac] and cardiac autonomic responses after exercise for both the applications. PMID- 29177981 TI - Long-term incidence of inappropriate shocks in patients with implantable cardioverter defibrillators in clinical practice-an underestimated complication? AB - BACKGROUND: Implantable cardioverter defibrillators (ICD) are life-saving device therapy, and patients often carry devices for decades with interim pulse generator exchanges. Inappropriate shocks are associated with impaired quality of life and increased mortality, but available data on their incidence and etiology outside of clinical trials is limited and usually restricted to the lifespan of a singular device. We hypothesized that the incidence in clinical practice is underestimated and aimed this study to retrospectively assess the long-term incidence and etiology of inappropriate shocks in a real-world cohort of patients with multiple ICDs over a long follow-up period. METHODS: Patients with ICDs implanted between 1998 and 2012 in two Swiss cardiology departments and at least one device exchange in the same department thereafter were included in this cohort. Retrospective analysis with follow-up until 2016 was conducted to assess incidence and etiology of inappropriate ICD shocks. RESULTS: Two hundred forty nine ICDs were implanted in 100 patients (mean age: 60.1 +/- 11.7; 80% male). Over a mean follow-up time of 11.2 (+/- 3.6) years, 555 shocks occurred in 55 patients. One hundred twenty-three (22%) shocks in 23 (23%) patients were inappropriate. Supraventricular arrhythmia and oversensing were the most frequent causes of inappropriate shock. Patients with younger age or previous supraventricular arrhythmias were at increased risk of inappropriate shocks. Patients with inappropriate shocks during the lifespan of their first ICD were at increased risk for inappropriate shocks in subsequent devices. CONCLUSIONS: Inappropriate shocks are an underestimated and frequent problem in clinical practice with an incidence that may exceed numbers of previously reported clinical trials with shorter follow-up periods. Patients at increased risk for inappropriate shocks need careful evaluation of potential therapeutic optimization strategies including pharmacological treatment, device programming, electrophysiological ablation, device downgrading, and telemonitoring. PMID- 29177983 TI - Ask the rheumatologist online: a qualitative analysis of a web-based service. AB - The objective of this study was to analyze the use of an Ask-the-Rheumatologist website service. All questions submitted were analyzed for gender, geographic location, topic area, disease, appropriateness, personal experience, and whether the answer is found elsewhere on the hosting website. The number of total visits and their geographic location was determined. The web service was visited 7985 times. Two hundred twenty-seven questions were submitted, with a majority related to personal experience and inflammatory rheumatic disease. One hundred six questions did not have answers available elsewhere on the website. Seventy questions were deemed inappropriate. Ask-the-Rheumatologist was visited frequently, demonstrating an innovative method of knowledge-transfer between health professionals, patients, and the general public. PMID- 29177982 TI - Two in one is better than one plus one: comparison of adverse events between combining electrophysiological examination and coronary angiography versus performing them consecutively. AB - PURPOSE: In some patients, both an electrophysiological examination (EPS) and a coronary angiography (CA) are necessary. It might be preferable to choose a combined approach of EPS and CA versus performing them consecutively. The purpose of this study is to evaluate the type and rate of adverse events between both approaches. METHODS: Patients were eligible if they underwent a CA and an EPS in a combined approach or in a time interval of at most 2 months. In all patients, clinical adverse events were recorded. RESULTS: A total of 1184 patients were included. CA and EPS were performed in a combined procedure (comb) in 492 patients, whereas they were performed consecutively in 692 patients (cons). The acute major complication rate was 0.67%, showing no differences between both groups. In the comb 6.9% and in the cons 6.6% of vascular complications were observed (p = 0.20). The rates of AV fistula and hematoma needing transfusion showed a significantly higher rate in the cons group (p = 0.018 and p = 0.045, respectively). In a multivariate logistic regression analysis, age was a significant predictor for groin complications. After propensity matching, AV fistula occurred significantly more often in the cons group (p = 0.002). CONCLUSION: Overall, serious adverse events were rare and there were no differences between the combined approach of EPS and CA and the consecutive approach; however, the occurrence of AV fistula and groin hematoma needing transfusion occurred significantly less in the combined procedure group. Therefore, a combined approach is preferable to a consecutive one. PMID- 29177984 TI - Clinical characteristics of conduction disturbance in patients with Behcet's disease. AB - To summarized clinical features of Behcet's patients with conduction disturbances and explore the underlying risk factors. A retrospective case-control study was conducted in Anzhen Hospital, Capital Medical University. Demographic data, clinical features, laboratory results, treatments, and fatality rate during hospital stay were analyzed. We found 23.1% of Behcet's disease had conduction disturbances and 84.0% had aortic valvular insufficiency. The male percentage of the Behcet's disease patients with conduction disturbances was significantly higher than controls (88.9 vs. 61.7%, P = 0.03). The echocardiography showed left ventricular end-diastolic diameter [64.00 (18) vs. 48.00 (15) mm, P = 0.000]; left ventricular end-contraction diameter [47.50 (11) vs. 30 (13) mm, P = 0.000]; left atrial diameter [47 (17) vs. 34 (14) mm, P = 0.001]; and left ventricular ejection fraction [60 (10) vs. 63 (13) mm, P = 0.023] were significantly different between two groups. Aortic valvular insufficiency was an independent risk factor for Behcet's disease with conduction disturbances (OR = 17.830; 95% CI 2.106, 150.981; P = 0.008). Conduction disturbance in Behcet's disease deserved attention. The diagnosis of BD and evaluation of conduction disturbance should be kept in mind when accepting patients with valvular regurgitation. PMID- 29177985 TI - Erratum to: Oxygen Transport to Tissue XXXIV. PMID- 29177986 TI - Metallurgy of soft spheres with hard core: From BCC to Frank-Kasper phases. AB - Understanding how soft particles can fill the space is still an open question. Structures far from classical FCC or BCC phases are now commonly experimentally observed in many different systems. Models based on pair interaction between soft particles are at present much studied in 2D. Pair interactions with two different lengths have been shown to lead to quasicrystalline architectures. It is also the case for a hard core with a square repulsive shoulder potential. In 3D, global approaches have been proposed for instance by minimizing the interface area between the deformed objects in the case of foams or micellar systems or using a self-consistent mean-field theory in copolymer melts. In this paper we propose to compare a strong van der Waals attraction between spherical hard cores and an elastic energy associated to the deformation of the soft corona. This deformation is measured as the shift between the deformed shell compared to a corona with a perfect spherical symmetry. The two main parameters in this model are: the hard core volume fraction and the weight of the elastic energy compared to the van der Waals one. The elastic energy clearly favours the BCC structure but large van der Waals forces favor Frank and Kasper phases. This result opens a route towards controlling the building of nanoparticle superlattices with complex structures and thus original physical properties. PMID- 29177987 TI - A case of an elderly man who required repeated repair of a ventricular septal defect and tricuspid rupture after blunt chest trauma. AB - Several cases of traumatic ventricular septal defect (VSD) have been reported. However, traumatic VSD complicated by tricuspid rupture is rare. We report a case of traumatic VSD with tricuspid rupture who required repeated repair of both conditions. A 69-year-old man was transferred to our hospital for emergent surgical repair of traumatic VSD and tricuspid rupture. Although emergent repair was performed, a new left-to-right shunt and moderate tricuspid regurgitation appeared during his postoperative course. A reoperation was performed 4 months after the first operation. The borders of the defect were very fibrotic and strong compared with those in the first operation. Surgical treatment of traumatic VSD should be postponed in hemodynamically stable patients. When emergent repair is performed, careful follow-up is necessary to diagnose new VSD. PMID- 29177988 TI - Early Life Characteristics and Neurodevelopmental Phenotypes in the Mount Sinai Children's Environmental Health Center. AB - Neurodevelopmental outcomes including behavior, executive functioning, and IQ exhibit complex correlational structures, although they are often treated as independent in etiologic studies. We performed a principal components analysis of the behavioral assessment system for children, the behavior rating inventory of executive functioning, and the Wechsler scales of intelligence in a prospective birth cohort, and estimated associations with early life characteristics. We identified seven factors: (1) impulsivity and externalizing, (2) executive functioning, (3) internalizing, (4) perceptual reasoning, (5) adaptability, (6) processing speed, and (7) verbal intelligence. Prenatal fish consumption, maternal education, preterm birth, and the home environment were important predictors of various neurodevelopmental factors. Although maternal smoking was associated with more adverse externalizing, executive functioning, and adaptive composite scores in our sample, of the orthogonally-rotated factors, smoking was only associated with the impulsivity and externalizing factor ([Formula: see text] - 0.82, 95% CI - 1.42, - 0.23). These differences may be due to correlations among outcomes that were accounted for by using a phenotypic approach. Dimension reduction may improve upon traditional approaches by accounting for correlations among neurodevelopmental traits. PMID- 29177989 TI - Consumption of caffeinated beverages and serum concentrations of sex steroid hormones in US men. AB - BACKGROUND: By modulating the levels of sex steroid hormones and sex hormone binding globulin (SHBG), caffeine could be a factor in the development of several conditions in men, including prostate cancer. The aim of this study was to evaluate if caffeine consumption is associated with concentrations of sex steroid hormones and SHBG in men. METHODS: 1,410 men aged 20 + years who attended the morning examination session of the Third National Health and Nutrition Examination Survey (1988-1991) were included in the analysis. Coffee and soft drink consumption was assessed using a food frequency questionnaire. Daily caffeine intake was estimated by multiplying caffeine content per cup times the daily frequency of coffee, tea, or soft drink consumption. Serum levels of hormones and SHBG were measured by immunoassay. Associations of frequency of beverage consumption or estimated caffeine intake with hormone levels were examined using multivariable linear regression. RESULTS: Coffee consumption was positively associated with SHBG concentration (p = 0.045) taking lifestyle factors into account, but mutually adjusting for testosterone and estradiol attenuated the association; no association with SHBG was observed for soft drink consumption or caffeine intake. No associations between caffeinated beverage consumption and androgen or estrogen concentrations were observed. CONCLUSION: Men who drink coffee more frequently may have higher circulating SHBG concentration, but there were no consistent associations for soft drinks or caffeine intake.

AB - The macauba palm (Acrocomia aculeata) is native of tropical America and is found mostly in the Cerrados and Pantanal biomes. The fruits provide an oily pulp, rich in long chain fatty acids, and a kernel that encompass more than 50% of lipids rich in medium chain fatty acids (MCFA). Based on biochemical and nutritional evidences MCFA is readily catabolized and can reduce body fat accumulation. In this study, an animal model was employed to evaluate the effect of Acrocomia aculeata kernel oil (AKO) on the blood glucose level and the fatty acid deposit in the epididymal adipose tissue. The A. aculeata kernel oil obtained by cold pressing presented suitable quality as edible oil. Its fatty acid profile indicates high concentration of MCFA, mainly lauric, capric and caprilic. Type 2 diabetic rats fed with that kernel oil showed reduction of blood glucose level in comparison with the diabetic control group. Acrocomia aculeata kernel oil showed hypoglycemic effect. A small fraction of total dietary medium chain fatty acid was accumulated in the epididymal adipose tissue of rats fed with AKO at both low and high doses and caprilic acid did not deposit at all. PMID- 29177993 TI - Classification of hospital admissions into emergency and elective care: a machine learning approach. AB - Rising admissions from emergency departments (EDs) to hospitals are a primary concern for many healthcare systems. The issue of how to differentiate urgent admissions from non-urgent or even elective admissions is crucial. We aim to develop a model for classifying inpatient admissions based on a patient's primary diagnosis as either emergency care or elective care and predicting urgency as a numerical value. We use supervised machine learning techniques and train the model with physician-expert judgments. Our model is accurate (96%) and has a high area under the ROC curve (>.99). We provide the first comprehensive classification and urgency categorization for inpatient emergency and elective care. This model assigns urgency values to every relevant diagnosis in the ICD catalog, and these values are easily applicable to existing hospital data. Our findings may provide a basis for policy makers to create incentives for hospitals to reduce the number of inappropriate ED admissions. PMID- 29177994 TI - Are shocks to renewable energy consumption permanent or temporary? Evidence from 54 developing and developed countries. AB - The renewable energy sources are considered as the important factor to decrease the level of carbon emissions and to promote the global green economy. Understanding the dynamics of renewable energy consumption, this paper analyzes whether there is a unit root in renewable energy consumption in 54 countries over the period 1971-2016. To this end, the unit root test of Narayan-Popp with two endogenous (unknown) breaks is implemented. The paper finds that renewable energy consumption series are stationary around a level and the time trend in 45 of 54 countries. In other words, renewable energy consumption follows a unit root process only in nine countries: Brazil, China, Colombia, India, Israel, Japan, the Netherlands, Spain, and Turkey. The evidence implies that renewable energy demand policies, which aimed to decrease the carbon emissions, will only have permanent effects in those nine countries. PMID- 29177995 TI - Photocatalytic decomposition of N2O over g-C3N4/WO3 photocatalysts. AB - Although the nitrous oxide belongs among three of the most contributing greenhouse gases to global warming, it is quite neglected by photocatalytic society. The g-C3N4 and WO3 composites were therefore tested for the photocatalytic decomposition of N2O for the first time. The pure photocatalysts were prepared by simple calcination of precursors, and the composites were prepared by mixing of suspension of pure components in water followed by calcination. The structural (X-ray diffraction, X-ray photoelectron spectroscopy, high-resolution transmission electron microscopy), textural (N2 physisorption), and optical properties (diffuse reflectance spectroscopy, photoluminescence spectroscopy, photoelectrochemical measurements) of all composites were correlated with photocatalytic activity. The experimental results and results from characterization techniques confirmed creation of Z-scheme in the WO3/g-C3N4 composites, which was confirmed by hydroxyl radicals' trapping measurements. The photocatalytic decomposition of N2O was carried out in the presence of UVA light (peak intensity at 365 nm) and the 1:2 WO3/g-C3N4 composite was the most active one, but the photocatalytic activity was just negligibly higher than that of pure WO3. This is caused by relatively weak interaction between WO3 and g-C3N4 which was revealed from XPS. PMID- 29177996 TI - Heavy-metal speciation redistribution in solid phase and potential environmental risk assessment during the conversion of MSW incineration fly ash into molten slag. AB - The alkalinity (AKash), BCR sequential extraction method, and principle component analysis (PCA) were adopted to investigate the heavy-metal partitioning and their speciation redistribution in solid phase in ash-melting process. The results indicated that the conversion of Zn-OXI (oxidisable fraction) into Zn-RES (residual fraction) and the decomposition of Cu-OXI fraction were prevailing in solid-phase reaction. Moreover, the alkalinity reduction from AKash = 2.0 to AKash = 1.2 had positive implications for the concentration reduction of As-RED (reducible fraction), Zn-RED, and Pb-RES fractions in slags. The modified synthesis toxicity index (STIM) calculation model was introduced to investigate the potential ecological risk (PEI) of heavy metals in the recycling and utilization of molten slag. Based on STIM calculation model, PEI of heavy metal in hazardous materials was classified into five ranks, such as serious pollution (STIM > 462), heavy pollution (330 < STIM < 462), moderate pollution (132 < STIM < 330), mild pollution (0 < STIM < 132), and no pollution (STIM = 0). The molten slags produced from fly ash can be directly reused as building materials like freestone and ceramics due to the mild PEI. PMID- 29177997 TI - Study on diesel vertical migration characteristics and mechanism in water-bearing sand stratum using an automated resistivity monitoring system. AB - Oil spills frequently occur on both land and sea. Petroleum in mobile phase will cause serious pollution in the sediment and can form a secondary pollution source. Therefore, it is very important to study the migration of petroleum in sediments ideally in a rapid and simplified approach. The release of diesel was simulated using fine beach sand to construct a model aquifer, and dynamic monitoring was carried out using an automated monitoring system including a resistivity probe originally developed by our research group. The mobile phase migration fronts were determined accurately using wavelet analysis method combined with resistivity curve method. Then, a relationship between resistivity and the joint oil-water content was established. The main conclusions were as follows. The seepage velocity of the diesel with high mobility at the initial stage of infiltration was faster, followed by a period when gravity seepage was dominant, and finally a redistribution period at the later stage, which was mainly an oil-water displacement process. The resistivity trends for diesel infiltration in different water-saturated soil layers varied with depth. The resistivity in the vadose zone fluctuated significantly, increasing initially and later decreasing. The resistivity change in the capillary zone was relatively small and constant in the initial stage; then, it increased and subsequently decreased. The resistivity in the saturated zone was basically unchanged with depth, and the value became slightly larger than the background value over time. Overall, for a large volume of mobile phase diesel leakage, the arrival migration fronts can be detected by wavelet analysis combined with resistivity curves. The thickness of the oil slick in the capillary zone can be estimated by resistivity changes. The relationships between resistivity and both the moisture content and oil-water joint saturation are in agreement with the linear models. The research results provide basic data and a new data processing method for monitoring of contaminated sites following major oil spills using the resistivity method. PMID- 29177999 TI - Evaluation of sources and fate of nitrates in the western Po plain groundwater (Italy) using nitrogen and boron isotopes. AB - Diffuse nitrate pollution in groundwater is currently considered one of the major causes of water quality degradation. Determining the sources of nitrate contamination is an important first step for a better management of water quality. Thus, the isotopic composition of nitrate (delta15NNO3 and delta18ONO3) and boron (delta11B) were used to evaluate nitrate contamination sources and to identify geochemical processes occurring in the shallow and deep aquifers of the Turin-Cuneo plain (NW Italy). The study area is essentially an agricultural zone, where use of synthetic nitrogenous fertilizers and organic manure is a common practice and the connection to sewer services is locally lacking. Also livestock farming are highly developed. A groundwater sampling campaign was performed on 34 wells in the shallow aquifer and 8 wells in the deep aquifers, to analyze nitrate, chloride, boron, delta15NNO3, delta18ONO3 and delta11B. Isotope data of nitrate indicate that nitrate contamination in the Turin-Cuneo plain originates from mixtures of synthetic and organic sources, slightly affected by denitrification, and manure or septic tank effluents. Moreover, boron isotopes were used to discriminate further among the main anthropogenic sources of pollution. The analyses results confirm that both animal manure and domestic sewage, especially under the city of Turin, can contribute to the nitrate contamination. The isotope analysis was also used for the evaluation of denitrification and nitrification processes: contrary to expectations, a significant denitrification phenomenon was assessed only in the shallow unconfined aquifer, especially in the Poirino Plateau, the most contaminated sector of the study area. PMID- 29177998 TI - Fast trace determination of nine odorant and estrogenic chloro- and bromo phenolic compounds in real water samples through automated solid-phase extraction coupled with liquid chromatography tandem mass spectrometry. AB - A fast and reliable method was developed for simultaneous trace determination of nine odorous and estrogenic chloro- and bromo-phenolic compounds (CPs and BPs) in water samples using solid-phase extraction (SPE) coupled with liquid chromatography tandem mass spectrometry (LC-MS/MS). For sample preparation, the extraction efficiencies of two widely applied cartridges Oasis HLB and Sep-Pak C18 were compared, and the Oasis HLB cartridge showed much better extraction performance; pH of water sample also plays important role on extraction, and pH = 2-3 was found to be most appropriate. For separation of the target compounds, small addition of ammonium hydroxide can obviously improve the detection sensitivity, and the optimized addition concentration was determined as 0.2%. The developed efficient method was validated and showed excellent linearity (R 2 > 0.995), low limit of detection (LOD, 1.9-6.2 ng/L), and good recovery efficiencies of 57-95% in surface and tap water with low relative standard deviation (RSD, 1.3-17.4%). The developed method was finally applied to one tap and one surface water samples and most of these nine targets were detected, but all of them were below their odor thresholds, and their estrogen equivalent (EEQ) were also very low.

AB - The Po Valley is one of the most important hot spots in Europe for air pollution. Morphological features and anthropogenic pressures lead to frequent breaching of air quality standards and to high-pollution episodes in an ~46 * 103-km2-wide alluvial lowland. Therefore, it is increasingly important to study the air quality in a wide geographical scale to better implement possible and successful mitigation measures. The Veneto region lies in the eastern part of the Po Valley and the elemental composition of PM has been mainly studied in the Venice area, whereas scarce data are available for the remaining territory of the region. In this study, the elemental composition of PM2.5 was investigated over 1 year (2012 2013) at six major cities of the Veneto region. Samples were analyzed for 16 elements (Ca, Al, Fe, S, K, Mg, Ti, Mn, Zn, Ba, As, Ni, Pb, Sb, V, and Cu), and results were processed to investigate spatial and seasonal variations, the influence of meteorological factors, and the most probable sources by using a procedure based on (i) elemental ratios (Cu/Sb, Cu/Zn, Cu/Pb, Mn/V, V/Ni, and Zn/Pb), (ii) cluster analysis on wind data, and (iii) conditional probability function (CPF). The percentage of elements in PM2.5 ranged between 11 and 20%, and Ca and S were the most abundant elements in the region. Typical seasonal variations and similar trends were exhibited by each element, especially in the lowland. Some elements such as Zn, K, Mn, Pb, and Sb were found at high concentrations during the cold period. However, no similar dispersion processes were observed throughout the region, and their concentrations were mostly depending on individual local sources. In the alpine and foothill parts of the region, lower concentrations were recorded with respect to the Po Valley cities, which resulted enriched of most of the elements considered in this study. The cluster analysis on wind data and the CPF of the ratio-related sources demonstrated that a widespread pollution condition exists in the region, apart from the coastal area. However, specific directions (e.g., a link with high traffic roads, industrial areas, and airports) resulted the most probable explanation for each ratio-related source. In addition, the Veneto region hosts one of the most important Mediterranean ports for the cruise sector (Venice harbor), and its impact was previously demonstrated in the historical city center. In this study, the impact of Venice shipping emissions was estimated to be 3.5% of PM2.5 in some particular days.

AB - The emission profile of volatile organic compounds (VOCs) and nitric oxide (NO) in young and mature leaves of Croton floribundus was assessed in plants exposed to filtered air (FA) and ozone-enriched filtered air (FA+O3). After the period of exposure, leaves were enclosed in polyethylene terephthalate bags and VOCs were collected in young and mature leaves. Both young and mature leaves constitutively emitted the same VOC, but the concentrations were higher in young leaves. O3 exposure induced the emission of sesquiterpenes (mainly beta-caryophyllene) known as antioxidant compounds that may scavenge O3. Young leaves were the highest emitters of sesquiterpenes. O3 induced a rapid accumulation of NO in different tissues and leaf developmental stages; this accumulation was marked in palisade and spongy parenchyma cells in young and mature leaves, respectively. O3 altered the levels of the signaling compound methyl salicylate (MeSA). Moreover, our data showed that NO together with VOC emissions, such as geranyl acetate, alpha cadiene, trans-farnesol, cis-beta-farnesene, and MeSA, participate of plant defense mechanisms against the oxidative damage caused by O3. PMID- 29178002 TI - Dysregulatory effects of retinoic acid isomers in late zebrafish embryos. AB - All-trans retinoic acid (atRA) and 9-cis retinoic acid (9cRA) are two natural derivatives of vitamin A that contribute to the normal vertebrate development by affecting gene expression through the retinoic acid signalling pathway. We show transcriptomic effects of the ectopic addition of atRA or 9cRA to zebrafish embryos at the posthatching embryonic stage. Exposure for 24 or 72 h to sublethal concentrations of both isomers resulted in characteristic transcriptome changes, in which many proliferation and development-related genes became underexpressed, whereas genes related to retinoid metabolism and some metabolic functions became overrepresented. While short and long exposures elicit essentially the same set of genes, atRA specifically induced expression of a specific subset of proteases, likely acting at the extracellular level, and of elements of the response to xenobiotics. These results reflect the well-known antiproliferative activity of retinoids, and they suggest a dysregulation of the developmental process at final stages of embryogenesis. They also indicate a potential role of endopeptidases as markers of developmental alterations, as well as their possible control by the retinoic signalling pathway. We propose to monitor mRNA levels of cyp16a, cyp16b, and cyp16c in zebrafish embryos as a bioassay for retinoid disruption. PMID- 29178004 TI - PCDD/PCDF formation in the chlor-alkali process-laboratory study and comparison with patterns from contaminated sites. AB - Studies on the formation of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) during the electrolysis of sodium chloride solution (brine) using graphite or titanium electrodes were carried out at a laboratory scale. High concentrations of PCDFs but no PCDDs were formed in tests using graphite electrodes. With titanium electrodes, PCDFs were only formed when tar pitch was added and mainly originated from the dibenzofuran present in the tar. For the first time, a detailed assessment of the formation of mono- to octachlorinated PCDD/PCDF from tar pitch was investigated. The assessment included of the chlorination steps proved that PCDFs were formed by successive lateral chlorinated from dibenzofuran to MonoCDFs, DiCDFs, and TriCDFs to form the typical known "chlorine pattern" of TetraCDF to OctaCDF with a dominance of 1,2,7,8- and 2,3,7,8-TetraCDFs, 1,2,3,7,8-PentaCDF, and 1,2,3,4,7,8-HexaCDF as marker congeners. The final homologue distributions depended on reaction time and reaction temperature. In addition, electrolysis with non-chlorinated dibenzo-p dioxins, dibenzofuran, and biphenyl was carried out. As a result, PCDDs, PCDFs, and PCB were formed at comparable yields. Congener patterns in soil samples from a PCDD/F-contaminated site where chlor-alkali electrolysis had been operated for decades in Japan had identical isomer distribution demonstrating the source and contamination potential and risk of these processes. Therefore, sites where in the past 120 years chlor-alkali electrolysis has been operated or where residues from chlor-alkali production or other chlorine using industries have been disposed should be assessed for their pollution level and exposure relevance. The assessment of total organohalogen content revealed that PCDF is only a small fraction of organohalogens in the contaminated soils. For an appropriate risk assessment, also other chlorinated aromatic compounds such as PCBs or PCNs need to be considered. PMID- 29178003 TI - Enhanced phosphorus removal using acid-treated magnesium slag particles. AB - Magnesium-enriched magnesium slag particles (MSPs) can be used as an adsorption substrate as well as the magnesium source for struvite precipitation. In this study, an HCl treatment was used to enhance MSPs for phosphorus removal. After soaking in 1 mol/L HCl, an 11.27% decrease in median diameter (D50) and a 6.73% increase in specific surface area were observed when compared with the original MSPs. The improvement of the MSP surface properties resulted in 188.96 mg/kg increase in the PO43- adsorption capacity. Irrespective of HCl treatment, the phosphorus adsorption process followed the Dubinin-Radushkevich (D-R) model much more accurately than the Langmuir and Freundlich equations with correlation coefficients higher than 0.94. The adsorption free energy obtained through the D R model revealed a 9.75% decrease after HCl treatment. Sequential fraction extraction results indicated that 96% of the Mg2+ released from the HCl-treated MSPs came from acid-soluble magnesium (exchangeable and carbonate-bound). Mg2+ obtained from HCl-treated solutions provided a reliable magnesium source for struvite precipitation. The PO43- removal rate can reach 53.63% with the optimal pH value of 10.0 and molar ratio of NH4+ to PO43- of 1:1. Struvite precipitation and adsorption can simultaneously occur in HCl-treated MSP solution. It contributed 63.19% to the overall PO43- removal and is a major contributor compared with adsorption. Thus, HCl treatment greatly enhanced the potential of MSPs for phosphorus removal due to an improved adsorption capacity and is a reliable Mg2+ source for struvite precipitation. PMID- 29178005 TI - Effect of single and repeated heat stress on chemical signals of heat shock response cascade in the rat's heart. AB - Exposure to sublethal heat stress activates a complex cascade of signaling events, such as activators (NO), signal molecules (PKCepsilon), and mediators (HSP70 and COX-2), leading to implementation of heat preconditioning, an adaptive mechanism which makes the organism more tolerant to additional stress. We investigated the time frame in which these chemical signals are triggered after heat stress (41 +/- 0.5 degrees S/45 min), single or repeated (24 or 72 h after the first one) in heart tissue of male Wistar rats. The animals were allowed to recover 24, 48 or 72 h at room temperature. Single heat stress caused a significant increase of the concentration of HSP70, NO, and PKC level and decrease of COX-2 level 24 h after the heat stress, which in the next course of recovery gradually normalized. The second heat stress, 24 h after the first one, caused a significant reduction of the HSP70 levels, concentration of NO and PKCE, and significant increase of COX-2 concentration. The second exposure, 72 h after the first heat stress, caused more expressive changes of HSP70 and NO in the 24 h recovery groups. The level of PKCE was not significantly changed, but there was significantly increased COX-2 concentration during recovery. Serum activity of AST, ALT, and CK was reduced after single exposure and increased after repeated exposure to heat stress, in both time intervals. In conclusion, a longer period of recovery (72 h) between two consecutive sessions of heat stress is necessary to achieve more expressive changes in mediators (HSP70) and triggers (NO) of heat preconditioning.

PMID- 29178008 TI - Trace-metal contamination in the glacierized Rio Santa watershed, Peru. AB - The objective of this research is to characterize the variability of trace metals in the Rio Santa watershed based on synoptic sampling applied at a large scale. To that end, we propose a combination of methods based on the collection of water, suspended sediments, and riverbed sediments at different points of the watershed within a very limited period. Forty points within the Rio Santa watershed were sampled between June 21 and July 8, 2013. Forty water samples, 36 suspended sediments, and 34 riverbed sediments were analyzed for seven trace metals. The results, which were normalized using the USEPA guideline for water and sediments, show that the Rio Santa water exhibits Mn concentrations higher than the guideline at more than 50% of the sampling points. As is the second highest contaminating element in the water, with approximately 10% of the samples containing concentrations above the guideline. Sediments collected in the Rio Santa riverbed were heavily contaminated by at least four of the tested elements at nearly 85% of the sample points, with As presenting the highest normalized concentration, at more than ten times the guideline. As, Cd, Fe, Pb, and Zn present similar concentration trends in the sediment all along the Rio Santa.The findings indicate that care should be taken in using the Rio Santa water and sediments for purposes that could affect the health of humans or the ecosystem. The situation is worse in some tributaries in the southern part of the watershed that host both active and abandoned mines and ore-processing plants. PMID- 29178007 TI - Correction to: Pharmacokinetics of Fentanyl and Its Derivatives in Children: A Comprehensive Review. AB - Fentanyl and its derivatives sufentanil, alfentanil, and remifentanil are potent opioids. A comprehensive review of the use of fentanyl and its derivatives in the pediatric population was performed using the National Library of Medicine PubMed. Studies were included if they contained original pharmacokinetic parameters or models using established routes of administration in patients younger than 18 years of age. Of 372 retrieved articles, 44 eligible pharmacokinetic studies contained data of 821 patients younger than 18 years of age, including more than 46 preterm infants, 64 full-term neonates, 115 infants/toddlers, 188 children, and 28 adolescents. Underlying diagnoses included congenital heart and pulmonary disease and abdominal disorders. Routes of drug administration were intravenous, epidural, oral-transmucosal, intranasal, and transdermal. Despite extensive use in daily clinical practice, few studies have been performed. Preterm and term infants have lower clearance and protein binding. Pharmacokinetics was not altered by chronic renal or hepatic disease. Analyses of the pooled individual patients' data revealed that clearance maturation relating to body weight could be best described by the Hill function for sufentanil (R 2 = 0.71, B max 876 mL/min, K 50 16.3 kg) and alfentanil (R 2 = 0.70, B max (fixed) 420 mL/min, K 50 28 kg). The allometric exponent for estimation of clearance of sufentanil was 0.99 and 0.75 for alfentanil clearance. Maturation of remifentanil clearance was described by linear regression to bodyweight (R 2 = 0.69). The allometric exponent for estimation of remifentanil clearance was 0.76. For fentanyl, linear regression showed only a weak correlation between clearance and bodyweight in preterm and term neonates (R 2 = 0.22) owing to a lack of data in older age groups. A large heterogeneity regarding study design, clinical setting, drug administration, laboratory assays, and pharmacokinetic estimation was observed between studies introducing bias into the analyses performed in this review. A limitation of this review is that pharmacokinetic data, based on different modes of administration, dosing schemes, and parameter estimation methods, were combined. PMID- 29178009 TI - Gap junction channels as potential targets for the treatment of major depressive disorder. AB - BACKGROUND: Major depressive disorder (MDD) remains a major public health problem worldwide. The association between MDD and the dysfunction of gap junction channels (GJCs) in glial cells, especially astrocytes, is still controversial. OBJECTIVE: This review provides an overview of the role of astrocyte GJCs in LMDD. RESULTS: Exposure to chronic unpredictable stress caused a reduction in connexin expression in the rat prefrontal cortex, a result that is consistent with clinical findings reported in postmortem studies of brains from MDD patients. Chronic antidepressant treatment in these rats increased the expression of connexins. However, pharmacological GJC blockade in normal rodents decreased connexin expression and caused depressive-like behaviors. Furthermore, GJC dysfunction affects electrical conductance, metabolic coupling and secondary messengers, and inflammatory responses, which are consistent with current hypotheses on MDD. All these results provide a comprehensive overview of the neurobiology of MDD. CONCLUSION: This review supports the hypothesis that the regulation of GJCs between astrocytes could be an underlying mechanism for the therapeutic effect of antidepressants. PMID- 29178011 TI - Pyridoxine-dependent epilepsies: an observational study on clinical, diagnostic, therapeutic and prognostic features in a pediatric cohort. AB - The aim of our study was to describe the clinical, electroencephalogram, molecular findings and the diagnostic and therapeutic flow-chart of children with pyridoxine-dependent epilepsies (PDEs). We performed a retrospective observational study on children with PDEs, diagnosed and followed-up in Italian Pediatric Departments. In each centre, the authors collected data from a cohort of children admitted for intractable seizures, responsive to pyridoxine administration and resistant to other anticonvulsant therapies. Data were retrospectively analysed from January 2016 to January 2017. Sixteen patients (13 males, and 3 females) were included. We found that 93.75% of patients underwent conventional anticonvulsant therapy before starting pyridoxine administration and 62.5% had ex-juvantibus diagnosis, as specific serum diagnostic tests had been performed in only 37.5% of patients by alpha-AASA and pipecolic acid blood and urine dosage. The most common type of seizure was generalized tonic-clonic in 7 patients and the most common EEG pattern was characterized by a "burst suppression" pattern. Before pyridoxine administration, other anticonvulsant drugs were used in 93.75% of patients, with consequent onset of drug-resistance. Phenobarbital was the most frequently used drug as first-line treatment. The importance of our study relies on the need of a deeper knowledge of PDEs in terms of early diagnosis, avoiding incorrect treatment and related adverse events, clinical and EEG pathognomonic features, and genetic aspects of the disease. PMID- 29178010 TI - Psychedelics and reconsolidation of traumatic and appetitive maladaptive memories: focus on cannabinoids and ketamine. AB - RATIONALE: Clinical data with 3,4-methylenedioxymethamphetamine (MDMA) in post traumatic stress disorder (PTSD) patients recently stimulated interest on the potential therapeutic use of psychedelics in disorders characterized by maladaptive memories, including substance use disorders (SUD). The rationale for the use of MDMA in PTSD and SUD is being extended to a broader beneficial "psychedelic effect," which is supporting further clinical investigations, in spite of the lack of mechanistic hypothesis. Considering that the retrieval of emotional memories reactivates specific brain mechanisms vulnerable to inhibition, interference, or strengthening (i.e., the reconsolidation process), it was proposed that the ability to retrieve and change these maladaptive memories might be a novel intervention for PTSD and SUD. The mechanisms underlying MDMA effects indicate memory reconsolidation modulation as a hypothetical process underlying its efficacy. OBJECTIVE: Mechanistic and clinical studies with other two classes of psychedelic substances, namely cannabinoids and ketamine, are providing data in support of a potential use in PTSD and SUD based on the modulation of traumatic and appetitive memory reconsolidation, respectively. Here, we review preclinical and clinical data on cannabinoids and ketamine effects on biobehavioral processes related to the reconsolidation of maladaptive memories. RESULTS: We report the findings supporting (or not) the working hypothesis linking the potential therapeutic effect of these substances to the underlying reconsolidation process. We also proposed possible approaches for testing the use of these two classes of drugs within the current paradigm of reconsolidation memory inhibition. CONCLUSIONS: Metaplasticity may be the process in common between cannabinoids and ketamine/ketamine-like substance effects on the mediation and potential manipulation of maladaptive memories.

AB - In view of anxiolytic, antidepressant and memory strengthen properties of Allium cepa (AC; onion) bulb in various investigations; we aimed to evaluate the useful effects of onion on single immobilization stress -induced biochemical and behavioral changes. Mice in test group were treated with AC powder (200 mg/kg/day), dissolved in water, while the control group were received drinking water for 14 days. After 14 days control and AC treated mice were further divided into unstressed and stressed groups. Animals in the stressed group were subjected to immobilization stress for 2 h. 24-h after the immobilization stress, behavioral activities were monitored. Immobilization stress-induced an anxiogenic behavior in mice subjected to elevated plus maze test (EPM) and light dark activity test (LDA). 2-h immobilization stress-induced depressive behavior in animals measured by forced swim test (FST). Administration of AC attenuated the immobilization stress-induced behavioral deficits. Highest memory performance was observed in stressed mice that were pre-treated with AC in Morris water maze (MWM). Brain lipid peroxidation, antioxidant enzymes (SOD, CAT, GPx) and acetylcholinesterase (AChE) activities were also estimated. Present study suggests a role of antioxidant enzymes in the attenuation of 2-h stress induced anxiety and depression, and enhanced cognitive function as well by AC. The findings therefore suggest that supplementation of AC may be beneficial in the treatment of anxiety, depression and enhancement of memory function. PMID- 29178013 TI - Research on the ability of propionic acid and vitamin B12 biosynthesis by Propionibacterium freudenreichii strain T82. AB - The purpose of this study was to determine the potential for biosynthesis of propionic acid and vitamin B12 by Propionibacterium freudenreichii T82 in a medium containing various sources of carbon (glucose, fructose, and saccharose). These sugars are present in apple pomaces, which are the waste from the production of apple juice. Using statistical analysis design of experiments (DoE), the results allowed us to determine which sugars (carbon sources) exert the most beneficial influence on the biosynthesis of propionic acid and cobalamin. The highest production of propionic acid by the tested bacterial strain was obtained in a medium in which glucose accounted for at least 50% of the available carbon sources. Depending on the culture medium, the concentration of this metabolite ranged from 23 to 40 g/L. P. freudenreichii T82 produced the smallest amount of acid in medium in which the dominant nutrient source was saccharose. The results obtained indicated an inverse relationship between the amount of acid produced by the bacteria and vitamin B12 biosynthesis. Because of the high efficiency of propionic acid biosynthesis by P. freudenreichii T82, the prospect of using this strain to obtain propionate with the simultaneous disposal of waste materials (such as apple pomaces) which contain glucose and/or fructose is very promising.

AB - The adsorption capacity of ground hazelnut (HS) and almond (AS) shells towards Pb(II) and Cd(II) has been studied at pH = 5, in NaNO3 and NaCl ionic media, in the ionic strength range 0.05-0.5 mol L-1. Kinetic and equilibrium experiments were carried out by using the Differential Pulse Anodic Stripping Voltammetry technique to check the amount of the metal ion removed by HS and AS materials. Different kinetic and equilibrium equations were used to fit experimental data and a statistical study was done to establish the suitable model for the data fitting. A speciation study of the metal ions in solution was also done in order to evaluate the influence of the ionic medium on the adsorption process. TGA-DSC, FT-IR, and SEM-EDX techniques were used to characterize the adsorbent materials. The mechanism of metal ions adsorption was explained on the basis of the results obtained by the metal ions speciation study and the characterization of materials. PMID- 29178015 TI - Spatiotemporal variation and exposure risk to human health of potential toxic elements in suburban vegetable soils of a megacity, SW China, 2012-2016. AB - Trace element contamination in soils of vegetable fields can threat public health. Seven potential toxic elements (As, Cd, Cr, Cu, Ni, Pb, and Zn) in suburban vegetable soils of Chengdu city, Southwest China, in 2012 and 2016, were analyzed to identify their sources with the spatiotemporal variation and assess their contamination and health risk for residents. The results showed that the concentrations of soil elements did not increase significantly in 2016 compared with that in 2012, whereas their spatial distributions altered markedly. The hot spots of soil As, Cd, and Pb as well as Cu and Zn in 2016 revealed the anthropogenic sources including agricultural activities, industrial emissions, road dust with heavy traffic, and open burning of solid waste. The apparent spatial difference of anthropogenic elements was related to the layout of land use surrounding the vegetable field. The contamination of soil elements decreased in the order of Cd > As ~ Zn > Cu ~ Pb > Cr ~ Ni in 2012 and Cd > Zn > As ~ Cu ~ Pb > Cr ~ Ni in 2016, and the vegetable soils were slightly to moderately contaminated by these elements through integrated contamination index. The sites affected by the trace elements did not increase in 2016 than in 2012, whereas the sites with relatively high contamination increased markedly. The non-carcinogenic risk of trace elements was generally acceptable, and children showed higher health risk than adults. The As carcinogenic risk for children varied between 5.48 * 10-5 and 1.59 * 10-4 in 2012 and between 4.40 * 10-5 and 1.82 * 10-4 in 2016, and the sites above acceptable levels (> 10-4) reached 60.6% and 48.5% in 2012 and 2016, respectively. The health risk of As in the vegetable soils should be paid more attention due to its high toxicity. PMID- 29178016 TI - Adsorption of cesium ion by marine actinobacterium Nocardiopsis sp. 13H and their extracellular polymeric substances (EPS) role in bioremediation. AB - This paper evaluates the cesium adsorption of marine actinobacterium Nocardiposis sp. 13H strain isolated from nuclear power plant sites in India. It could remove 88.6 +/- 0.72% of Cs+ from test solution containing 10 mM CsCl2. The biosorption of Cs+ with different environmental factors such as pH, temperature, and time interval is also determined. Scanning electron microscopy coupled with energy dispersive spectroscopy (EDS) confirmed the Cs+ adsorption by Nocardiopsis sp. 13H. Most of the bound cesium was found to be associated extracellular polymeric substances (EPS) suggesting its interaction with the surface active groups. The main component of the EPS was carbohydrate followed by protein and nucleic acid. Further, Fourier transform infrared (FTIR) spectroscopy suggested the carboxyl, hydroxyl, and amide groups on the strain cell surface were likely to be involved in Cs+ adsorption. Results from this study show Nocardiopsis sp. 13H microorganism could be useful in exploring the biosorption of radioisotope pollution and developing efficient and eco-friendly biosorbent for environmental cleanup. PMID- 29178017 TI - Study on the influential biochemical indices of Cd(II) on Eisenia fetida in oxidative stress by principal component analysis in the natural soil. AB - With the aggravation of heavy metal pollution in soil, the individual heavy metal content monitoring cannot predict the true effects of harmful substances on the ecosystems. Thus, the effective biological evaluation system should be established to assess the pollution risk caused by heavy metal. Earthworms are widely distributed in the soil, and at the bottom of the food chain, the changes of biochemical indices play an important role in the early warning for heavy metal pollution. Principal component analysis (PCA) is a statistical method that derives several independent principal components from the original variable based on retaining the information as much as possible. This paper is aimed at finding out and analyzing the key monitoring factors related to Cd2+ on the earthworm Eisenia fetida in oxidative stress. The Cd2+ stress concentrations were set at 0, 1, 10, 20, 100, 200, 400, and 800 mg kg-1, and the post-clitellum segment of earthworm was chosen to determine TP, POD, SOD, GST, GPX, CAT, MDA, VE, and AChE. The results showed that the main bioindicators associated with oxidative stress reaction were GST, POD, and MDA at the exposure time of 10 days; at 20 days GPX, MDA, and AChE; at 30 days CAT, TP, and GPX; CAT, MDA, and SOD at 40th day. These results indicated that PCA can quickly, effectively, directly, and scientifically select biomarkers of oxidative stress induced by Cd and improve the accuracy and scientificity of earthworm as a biomarker in monitoring and early warning for heavy metal-contaminated soil. PMID- 29178018 TI - Cu(II)-catalyzed degradation of ampicillin: effect of pH and dissolved oxygen. AB - Cu(II)-catalyzed hydrolysis of beta-lactam antibiotics has been well-identified and recognized as the key mechanism of antibiotic degradation. However, the overlooked Cu(II) oxidation susceptibly also plays an important role comparably with hydrolysis. This study evaluated the roles of hydrolysis and oxidation in Cu(II)-catalyzed degraded ampicillin (AMP), as a typical beta-lactam antibiotic, under relevant environmental conditions (pH 5.0, 7.0, and 9.0; oxygen 0.2 and 6.2 mg/L). Under AMP and Cu(II) molar ratio of 1:1, AMP degradation was the fastest at pH 9.0, followed by pH 5.0 and pH 7.0. The facilitation of oxygen on AMP degradation was notable at pH 5.0 and 7.0 rather than pH 9.0. AMP degradation rate increased from 21.8% in 0.2 mg/L O2 solution to 85.9% in 6.2 mg/L O2 solution at pH 7.0 after 4-h reaction. AMP oxidation was attributed to both oxygen-derived Cu(I)/Cu(II) cycle and intermediate reactive oxygen species (HO. and O2.-). Several intermediate and final products in AMP degradation were firstly identified by LC-quadrupole time-of-flight-MS analysis. Phenylglycine primary amine on the AMP structure was the essential complexation site to proceed with the oxidation reaction. The oxidation of AMP preferentially occurred on the beta-lactam structure. The inherent mechanisms related to pH and oxygen conditions were firstly investigated, which could enhance the understanding of both oxidation and hydrolysis mechanisms in AMP degradation. This study not only has an important implication in predicting beta-lactam antibiotic transformation and fate in natural environment but also benefits the developing of strategies of antibiotic control to reduce the environmental risk.

AB - INTRODUCTION: This study aimed to describe the efficacy of fulvestrant 500 mg in postmenopausal women with estrogen receptor (ER)-positive advanced/metastatic breast cancer who had disease progression after receiving anti-estrogen therapy in clinical practice, getting real-world data. MATERIALS AND METHODS: Multicenter, retrospective, observational study conducted in Spain. Postmenopausal women with locally advanced/metastatic ER-positive breast cancer who received treatment with fulvestrant 500 mg after progression with a previous anti-estrogen therapy were eligible. The primary endpoint was progression-free survival (PFS); secondary endpoints were overall survival (OS), clinical benefit rate (CBR), duration of clinical benefit (DoCB), and safety profile. RESULTS: A total of 263 women were evaluated (median age, 65.8 years). At a median follow-up of 21.5 months, median PFS and OS were 10.6 and 43.2 months, respectively. PFS according to 1st, 2nd, 3rd, and >= 4th lines were 11.5, 10.6, 9.9, and 8.5 months, respectively (p = 0.0245). PFS in patients with visceral involvement was 10 months vs 10.6 months in patients without visceral involvement (p = 0.6604), 9.6 months in patients with high Ki67 vs 10 months in patients with low Ki67 (p = 0.7224), and 10.2 months in HER2+ patients vs 10.3 months in HER2- patients (p = 0.6809). The CBR was 56.5% and the DoCB was 18.4 months. The most frequently adverse events were injection site pain (10.3%) and musculoskeletal disorders (7.6%). CONCLUSIONS: Fulvestrant 500 mg administered in clinical practice was shown to be effective (PFS, 10.6 months; CBR, 56.5%) and well tolerated, in accordance with previous trials.

AB - Epigenetics is the process by which gene expression is regulated by events other than alterations of the genome. This includes DNA methylation, histone modifications, chromatin remodeling, microRNAs, and long non-coding RNAs. Methylation of DNA, chromatin remodeling, and histone modifications regulate the chromatin and access of transcription factors to DNA and in turn gene transcription. Alteration of chromatin is now recognized to be deregulated in many cancers. Medulloblastoma is an embryonal tumor of the cerebellum and the most common malignant brain tumor in children, that occurs only rarely in adults. Medulloblastoma is characterized by four major molecularly and histopathologically distinct groups, wingless (WNT), sonic hedgehog (SHH), group 3 (G3), and group 4 (G4), that, except for WNT, are each now subdivided in several subgroups. Gene expression array, next-generation sequencing, and methylation profiling of several hundred primary tumors by several consortia and independent groups revealed that medulloblastomas harbor a paucity of mutations most of which occur in epigenetic regulators, genetic alterations in oncogenes and tumor suppressors, in addition to copy number alterations and chromosome gains and losses. Remarkably, some tumors have no reported mutations, suggesting that some genes required for oncogenesis might be regulated by epigenetic mechanisms which are still to be uncovered and validated. This review will highlight several epigenetic regulators focusing mainly on histone modifiers identified in medulloblastoma.

AB - BACKGROUND: This study aimed to examine the combined effect of pre-surgical emotion self-regulation (ESR) and symptoms of attention deficit hyperactivity disorder (sADHD, i.e., inattention, impulsivity, and hyperactivity) on weight loss 12 months following bariatric surgery independent of psychological distress and eating pathology. METHODS: Adults with obesity were recruited from a bariatric surgery specialty clinic in Canada. Patients completed measures of psychological distress (i.e., Beck Depression Inventory II and Beck Anxiety Inventory), eating pathology (i.e., Eating Disorder Examination Questionnaire), ESR (i.e., "Managing Own Emotions" subscale of the Schutte Emotional Intelligence Test), and sADHD (i.e., Adult ADHD Self-Report Scale) prior to surgery. Measures of height and weight were obtained and used to calculate percent excess weight loss (%EWL) of body mass index (BMI) pre- and 12 months post-surgery. RESULTS: Thirty-seven patients were recruited. The final sample consisted of 30 patients (80% female; mean age = 48 years; mean BMI = 49.32). Patients experienced significant weight loss and reported significant improvement in anxiety, depressed mood, and eating pathology from pre- to 12 months post-surgery. A significant sADHD by ESR interaction on %EWL (F(1, 21) = 6.43, p = .019) was observed and accounted for 13% of unique variance after adjusting for relevant covariates. Probing the interaction with the Johnson-Neyman technique indicated that there was a significant inverse association between sADHD and %EWL among individuals who scored <= 0.15 SD below the mean on ESR. CONCLUSIONS: ESR moderated the association between sADHD and %EWL, suggesting that sADHD may attenuate weight loss following bariatric surgery among individuals deficient in ESR. This finding has implications for bariatric surgery pre-surgical psychological assessment. PMID- 29178025 TI - Pegylated Liposomal Irinotecan Hydrochloride Trihydrate for Treating Pancreatic Cancer After Gemcitabine: An Evidence Review Group Perspective of a NICE Single Technology Appraisal. AB - The National Institute for Health and Care Excellence (NICE) invited the manufacturer (Shire Pharmaceuticals) of pegylated liposomal irinotecan hydrochloride trihydrate (liposomal irinotecan) to submit clinical and cost effectiveness evidence for its use in combination with 5-fluorouracil (5-FU) and folic acid/leucovorin (LV) for treating patients with pancreatic cancer following prior treatment with gemcitabine as part of the institute's Single Technology Appraisal process. The Liverpool Reviews and Implementation Group at the University of Liverpool was commissioned to act as the Evidence Review Group (ERG). This article presents a summary of the company's evidence, the ERG review and the resulting NICE guidance (TA440), issued on 26 April 2017. Clinical evidence for liposomal irinotecan + 5-FU/LV versus 5-FU/LV was derived from 236 patients with metastatic pancreatic cancer in the multinational, open-label, randomised controlled NAPOLI-1 trial. Results from analyses of progression-free survival and overall survival showed statistically significant improvements for patients treated with liposomal irinotecan + 5-FU/LV compared with those treated with 5-FU/LV. However, 5-FU/LV alone is rarely used in National Health Service clinical practice for patients with metastatic pancreatic cancer previously treated with gemcitabine. The company, ERG and Appraisal Committee (AC) all agreed that oxaliplatin + 5-FU/LV is the most commonly used treatment. Oxaliplatin + 5-FU/LV was compared with 5-FU/LV in two trials identified by the company. However, the company and the ERG both considered attempts to compare the efficacy of liposomal irinotecan + 5-FU/LV with oxaliplatin + 5-FU/LV to be methodologically flawed; not only was there heterogeneity between trials and their populations but also the proportional hazards assumption required to conduct a robust indirect treatment comparison (ITC) was violated. Nonetheless, data derived from an ITC were used to inform the company's economic model. Using the discounted patient access scheme price for liposomal irinotecan + 5-FU/LV, the company reported an incremental cost-effectiveness ratio (ICER) per quality adjusted life-year (QALY) gained of L54,412 for the comparison with oxaliplatin + 5-FU/LV. The ERG considered that the company's base-case cost-effectiveness results for the comparison of liposomal irinotecan + 5-FU/LV versus oxaliplatin + 5-FU/LV were underestimates and should be interpreted with extreme caution. Following implementation of a number of model amendments, the ERG's modified exploratory ICER for the comparison of liposomal irinotecan + 5-FU/LV versus oxaliplatin + 5-FU/LV was L106,898 per QALY gained. The AC accepted the majority of the ERG's amendments to the model, and also highlighted that the total QALYs for oxaliplatin + 5-FU/LV were lower than for 5-FU/LV in the company's model, which the AC considered to be clinically implausible. The AC therefore considered results from exploratory analyses, undertaken by the ERG, which included altering the QALY difference between liposomal irinotecan + 5-FU/LV and oxaliplatin + 5 FU/LV by +/- 10%. These analyses resulted in ICERs for the comparison of liposomal irinotecan + 5-FU/LV versus oxaliplatin + 5-FU/LV of between L201,019 per QALY gained to liposomal irinotecan + 5-FU/LV being dominated by oxaliplatin + 5-FU/LV. Therefore, despite uncertainty around the clinical-effectiveness evidence and cost-effectiveness results, the AC was confident that the ICER was in excess of L50,000 per QALY gained. The final guidance issued by NICE is that liposomal irinotecan + 5-FU/LV is not recommended within its marketing authorisation for treating metastatic adenocarcinoma of the pancreas in adults whose disease has progressed after gemcitabine-based therapy. PMID- 29178024 TI - Does EGFR Mutation Type Influence Patient-Reported Outcomes in Patients with Advanced EGFR Mutation-Positive Non-Small-Cell Lung Cancer? Analysis of Two Large, Phase III Studies Comparing Afatinib with Chemotherapy (LUX-Lung 3 and LUX Lung 6). AB - INTRODUCTION: In LUX-Lung 3 and LUX-Lung 6, afatinib significantly improved progression-free survival (PFS) versus chemotherapy in patients with tumors harboring common epidermal growth factor receptor (EGFR) mutations (Del19/L858R) and significantly improved overall survival (OS) in patients with tumors harboring Del19 mutations. Patient-reported outcomes stratified by EGFR mutation type are reported. PATIENTS AND METHODS: Lung cancer symptoms and health-related quality of life (QoL) were assessed every 21 days until progression using the EORTC Quality of Life Core Questionnaire C30 and its lung cancer-specific module, LC13. Analyses of cough, dyspnea, and pain were prespecified and included analysis of percentage of patients who improved on therapy, time to deterioration of symptoms, and change over time. Global health status (GHS)/QoL was also assessed. Analyses were conducted for all patients with tumors harboring Del19 or L858R mutations and were exploratory. RESULTS: Compared with chemotherapy, afatinib more commonly improved symptoms of, delayed time to deterioration for, and was associated with better mean scores over time for cough and dyspnea in patients with Del19 or L858R mutations. All three prespecified analyses of pain showed a trend favoring afatinib over chemotherapy. In both Del19 and L858R mutations, afatinib was also associated with improvements in GHS/QoL. Longitudinal analyses demonstrated statistically significant improvements in GHS/QoL for afatinib over chemotherapy for patients with tumors harboring Del19 mutations or L858R mutations. CONCLUSIONS: These exploratory analyses suggest first-line afatinib improved lung cancer-related symptoms and GHS/QoL compared with chemotherapy in patients with non-small-cell lung cancer with tumors harboring common EGFR mutations, with benefits in both Del19 and L858R patients. When considered with OS (Del19 patients only) and PFS benefits, these findings substantiate the value of using afatinib over chemotherapy in these patient groups.

AB - The viability, cellular uptake and subcellular distribution of heavy metal Hg, were determined in human mammary cell lines (MCF-7, MDA-MB-231 and MCF-10A). It was observed that Hg had the capacity of being excluded from the cells with a different type of possible transporters. MCF-7 cells showed the lowest viability, while the other two cell lines were much more resistant to Hg treatments. The intracellular concentration of Hg was higher at lower exposure times in MCF-10A cells and MCF-7 cells; but as the time was increased only MDA-MB-231 showed the capacity to continue introducing the metal. In MCF-7 and MCF-10A cells the subcellular distribution of Hg was higher in cytosolic fraction than nucleus and membrane, but MDA-MB-231 showed membrane and nucleus fraction as the enriched one. The analysis of RNA-seq about the genes or family of genes that encode proteins which are related to cytotoxicity of Hg evidenced that MCF-10A cells and MCF-7 cells could have an active transport to efflux the metal. On the contrary, in MDA-MB-231 no genes that could encode active transporters have been found. PMID- 29178027 TI - MRI Guiding of the Middle Cerebral Artery Occlusion in Rats Aimed to Improve Stroke Modeling. AB - The middle cerebral artery occlusion (MCAO) model in rats closely imitates ischemic stroke and is widely used. Existing instrumental methods provide a certain level of MCAO guidance, but monitoring of the MCA-occluding intraluminal filament position and possible complications can be improved. The goal of this study was to develop a MRI-based method of simultaneous control of the filament position, blood flow in the intracranial vessels, and hemorrhagic complications. Rats were subjected to either MRI-guided MCAO (group 1, n = 51) or MCAO without MRI control (group 2, n = 38). After operation, group 1 rats were transferred into a MRI scanner for the control of the filament position and possible complications. Ninety minutes after the onset of MCAO, the filament was removed in rats of both groups and MRI control of the infarct volume and hemorrhagic complications performed. High-resolution T1- and T2-weighted imaging performed immediately after filament insertion provided visualization of the filament position, blood flow in brain arteries, and complications related to inappropriate filament insertion. It permitted replacement of wrongly positioned filaments and exclusion of animals with complications from the experiment. MRI based MCAO guiding provided real-time intra-operational monitoring of crucial parameters determining MCAO suitability for stroke modeling, including better assessment of the operation outcomes in individual animals and significant enhancement of the model success rate. The possibility of simultaneous visualization of the filament, blood flow in the arteries, brain tissue, and hemorrhagic complications is the principal advantage of the proposed method over other instrumental methods of MCAO quality control. Graphical Abstract MRI-guided middle cerebral artery occlusion technique permits intra-operational monitoring via direct non-invasive simultaneous visualization of the filament, blood flow in the arteries, brain tissue, and hemorrhagic complications. It provides better assessment of MCAO outcomes in individual animals and significant enhancement of MCAO success rate. PMID- 29178028 TI - Non-invasive measurement of liver iron concentration using 3-Tesla magnetic resonance imaging: validation against biopsy. AB - OBJECTIVES: To evaluate the performance and limitations of the R2* and signal intensity ratio (SIR) methods for quantifying liver iron concentration (LIC) at 3 T. METHODS: A total of 105 patients who underwent a liver biopsy with biochemical LIC (LICb) were included prospectively. All patients underwent a 3-T MRI scan with a breath-hold multiple-echo gradient-echo sequence (mGRE). LIC calculated by 3-T SIR algorithm (LICSIR) and by R2* (LICR2*) were correlated with LICb. Sensitivity and specificity were calculated. The comparison of methods was analysed for successive classes. RESULTS: LICb was strongly correlated with R2* (r = 0.95, p < 0.001) and LICSIR (r = 0.92, p < 0.001). In comparison to LICb, LICR2* and LICSIR detect liver iron overload with a sensitivity/specificity of 0.96/0.93 and 0.92/0.95, respectively, and a bias +/- SD of 7.6 +/- 73.4 and 14.8 +/- 37.6 MUmol/g, respectively. LICR2* presented the lowest differences for patients with LICb values under 130 MUmol/g. Above this value, LICSIR has the lowest differences. CONCLUSIONS: At 3 T, R2* provides precise LIC quantification for lower overload but the SIR method is recommended to overcome R2* limitations in higher overload. Our software, available at www.mrquantif.org , uses both methods jointly and selects the best one. KEY POINTS: * Liver iron can be accurately quantified by MRI at 3 T * At 3 T, R2* provides precise quantification of slight liver iron overload * At 3 T, SIR method is recommended in case of high iron overload * Slight liver iron overload present in metabolic syndrome can be depicted * Treatment can be monitored with great confidence. PMID- 29178029 TI - Chemical shift magnetic resonance imaging for distinguishing minimal-fat renal angiomyolipoma from renal cell carcinoma: a meta-analysis. AB - OBJECTIVES: To determine the performance of chemical shift signal intensity index (CS-SII) values for distinguishing minimal-fat renal angiomyolipoma (mfAML) from renal cell carcinoma (RCC) and to assess RCC subtype characterisation. METHODS: We identified eligible studies on CS magnetic resonance imaging (CS-MRI) of focal renal lesions via PubMed, Embase, and the Cochrane Library. CS-SII values were extracted by lesion type and evaluated using linear mixed model-based meta regression. RCC subtypes were analysed. Two-sided p value <0.05 indicated statistical significance. Methodological quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. RESULTS: Eleven articles involving 850 patients were included. Minimal-fat AML had significantly higher CS SII value than RCC (p < 0.05); there were no significant differences between mfAML and clear cell RCC (cc-RCC) (p = 0.112). Clear cell RCC had a significantly higher CS-SII value than papillary RCC (p-RCC) (p < 0.001) and chromophobe RCC (ch-RCC) (p = 0.045). The methodological quality was relatively high, and Begg's test data points indicated no obvious publication bias. CONCLUSIONS: The CS-SII value for differentiating mfAML from cc-RCC remains unproven, but is a promising method for differentiating cc-RCC from p-RCC and ch-RCC. KEY POINTS: * RCC CS-SII values are significantly lower than those of mfAML overall. * CS-SII values cannot aid differentiation between mfAML and cc-RCC. * CS-SII values might help characterise RCC subtypes. PMID- 29178030 TI - Sensitivity to change and association of three-dimensional meniscal measures with radiographic joint space width loss in rapid clinical progression of knee osteoarthritis. AB - OBJECTIVE: To determine whether 3D meniscal measures had similar sensitivity to longitudinal change as cartilage thickness; to what extent these measures are associated with longitudinal joint space width (JSW) change; and whether the latter associations differ between minimum (mJSW) and fixed-location JSW. METHODS: Two-year changes in medial meniscal position and morphology, cartilage thickness (MRI) and minimum and fixed-location JSW (radiography) were determined in 35 Osteoarthritis Initiative knees [12 men, age: 67 (51-77) years; 23 women, age: 65 (54-78) years], progressing from baseline Kellgren-Lawrence grade <=2 to knee replacement within 3-5 years. Multiple linear regression assessed the features contributing to JSW change. RESULTS: Meniscal measures, cartilage thickness and JSW displayed similar sensitivity to change (standardised response mean<=|0.76|). Meniscal changes were strongly associated with JSW change (r<=|0.66|), adding <=20% to its variance in addition to cartilage thickness change. Fixed-location JSW change (multiple r2=72%) was more strongly related to cartilage and meniscal change than mJSW (61%). Meniscal morphology explained more of fixed-location JSW and meniscal position more of mJSW. CONCLUSION: Meniscal measures provide independent information in explaining the variance of radiographic JSW change. Fixed-location JSW appears to be more reflective of structural change than mJSW and, hence, a potentially superior measure of structural progression. KEY POINTS: * 3D positional/morphological meniscal measures change in rapidly progressing knees. * Similar sensitivity to 2-year change of quantitative meniscal/cartilage measures in rapid progression. * Changes in meniscal measures are strongly associated with radiographic JSW change. * Meniscal change provides information to explain JSW variance independent of cartilage. * Fixed-location JSW reflects structural disease stage more closely than minimum JSW. PMID- 29178032 TI - Lithium increases ammonium excretion leading to altered urinary acid-base buffer composition. AB - Previous reports identify a voltage dependent distal renal tubular acidosis (dRTA) secondary to lithium (Li+) salt administration. This was based on the inability of Li+-treated patients to increase the urine-blood (U-B) pCO2 when challenged with NaHCO3 and, the ability of sodium neutral phosphate or Na2SO4 administration to restore U-B pCO2 in experimental animal models. The underlying mechanisms for the Li+-induced dRTA are still unknown. To address this point, a 7 days time course of the urinary acid-base parameters was investigated in rats challenged with LiCl, LiCitrate, NaCl, or NaCitrate. LiCl induced the largest polyuria and a mild metabolic acidosis. Li+-treatment induced a biphasic response. In the first 2 days, proper urine volume and acidification occurred, while from the 3rd day of treatment, polyuria developed progressively. In this latter phase, the LiCl-treated group progressively excreted more NH4+ and less pCO2, suggesting that NH3/NH4+ became the main urinary buffer. This physiological parameter was corroborated by the upregulation of NBCn1 (a marker of increased ammonium recycling) in the inner stripe of outer medulla of LiCl treated rats. Finally, by investigating NH4+ excretion in ENaC-cKO mice, a model resistant to Li+-induced polyuria, a primary role of the CD was confirmed. By definition, dRTA is characterized by deficient urinary ammonium excretion. Our data question the presence of a voltage-dependent Li+-induced dRTA in rats treated with LiCl for 7 days and the data suggest that the alkaline urine pH induced by NH3/NH4+ as the main buffer has lead to the interpretation dRTA in previous studies. PMID- 29178031 TI - A predictive model for distinguishing radiation necrosis from tumour progression after gamma knife radiosurgery based on radiomic features from MR images. AB - OBJECTIVES: To develop a model using radiomic features extracted from MR images to distinguish radiation necrosis from tumour progression in brain metastases after Gamma Knife radiosurgery. METHODS: We retrospectively identified 87 patients with pathologically confirmed necrosis (24 lesions) or progression (73 lesions) and calculated 285 radiomic features from four MR sequences (T1, T1 post contrast, T2, and fluid-attenuated inversion recovery) obtained at two follow-up time points per lesion per patient. Reproducibility of each feature between the two time points was calculated within each group to identify a subset of features with distinct reproducible values between two groups. Changes in radiomic features from one time point to the next (delta radiomics) were used to build a model to classify necrosis and progression lesions. RESULTS: A combination of five radiomic features from both T1 post-contrast and T2 MR images were found to be useful in distinguishing necrosis from progression lesions. Delta radiomic features with a RUSBoost ensemble classifier had an overall predictive accuracy of 73.2% and an area under the curve value of 0.73 in leave-one-out cross validation. CONCLUSIONS: Delta radiomic features extracted from MR images have potential for distinguishing radiation necrosis from tumour progression after radiosurgery for brain metastases. KEY POINTS: * Some radiomic features showed better reproducibility for progressive lesions than necrotic ones * Delta radiomic features can help to distinguish radiation necrosis from tumour progression * Delta radiomic features had better predictive value than did traditional radiomic features. PMID- 29178033 TI - A review of Neuropathic Pain: From Guidelines to Clinical Practice. AB - : Neuropathic pain is a chronic condition representing a significant burden for patients, society, and healthcare systems. The prevalence of neuropathic pain in the general population has been estimated at 7-8% and is expected to increase in the future. Neuropathic pain differs from nociceptive pain and requires a different therapeutic approach; and the management of neuropathic pain is complicated and challenging. This chapter discusses clinical practice guidelines for neuropathic pain and their usefulness in clinical practice. FUNDING: Pfizer, Italy. PMID- 29178034 TI - Pharmacotherapy for Neuropathic Pain: A Review. AB - : Neuropathic pain, comprising a range of heterogeneous conditions, is often severe and difficult to manage, and this may result in a chronic condition that negatively affects the overall functioning and quality of life in patients. The pharmacotherapy of neuropathic pain is challenging and for many patients effective treatment is lacking; therefore, evidence-based recommendations are essential. Currently, there is general agreement on which drugs are appropriate for the first-line treatment of neuropathic pain, whereas debate continues regarding second- and third-line treatments. First-line drugs for neuropathic pain include antidepressants (tricyclic antidepressants and serotonin noradrenaline reuptake inhibitors) and anticonvulsants acting at calcium channels (pregabalin and gabapentin). Second- and third-line drugs for neuropathic pain include topical lidocaine and opioids. Although efficacious in the treatment of neuropathic pain, opioids are not considered to be a first choice because of adverse drug reactions and, more recently, because of concerns about abuse, diversion, and addiction. A clear understanding of the mechanism of action of currently available drugs is an essential step towards an effective clinical approach that aims to tailor therapies both to the specific neuropathic disease and to the needs of an individual patient. This review provides an overview of current drugs available for the treatment of neuropathic pain with an emphasis on their mechanism of action. FUNDING: Pfizer, Italy. PMID- 29178035 TI - A Review of the Emotional Aspects of Neuropathic Pain: From Comorbidity to Co Pathogenesis. AB - : Neuropathic pain is characterized by both sensory and affective disturbances, supporting the notion that pain and mood disorders share common pathogenetic mechanisms. Moreover, biological and neuroimaging data show that common brain areas are involved in the modulation of painful and emotional experiences. Improved understanding of the molecular mechanisms underlying the role of neuroinflammation in regulation of affective behavior in neuropathic pain states is important for the development of novel therapeutic strategies. Psychological issues must be considered a factor influencing treatment and outcome in patients with neuropathic pain. FUNDING: Pfizer, Italy. PMID- 29178036 TI - Neuropathic Pain and Sleep: A Review. AB - : Neuropathic pain is associated with sleep disturbances, and in turn poor sleep quality leads to increased pain sensitivity, so it is essential to assess sleep alongside neuropathic pain. Responses to drugs are inconsistent and identifying the best treatment option that will reduce pain and improve sleep quality remains challenging for clinicians. Anticonvulsants such as pregabalin and gabapentin improve neuropathic pain and have a positive effect on comorbid sleep disturbances. Opioids and antidepressants are effective in reducing pain but can exacerbate sleep disturbances. FUNDING: Pfizer, Italy. PMID- 29178037 TI - A Review of Neuropathic Pain: From Diagnostic Tests to Mechanisms. AB - : Neuropathic pain develops when the somatosensory nervous system is affected by a lesion or disease. Diagnostic tests aimed at assessing somatosensory afferent pathway damage are therefore useful for diagnosing neuropathic pain. Neuropathic pain manifests with a range of different symptoms such as ongoing burning pain, squeezing or pressure pain, paroxysmal electric shock-like sensations, stabbing pain, or mechanical dynamic allodynia. The various types of neuropathic pain are associated with different underlying nerve fiber abnormalities. This article summarizes the available methods of somatosensory afferent pathway assessment and discusses the potential pathophysiology underlying the most representative neuropathic pain types, i.e., ongoing burning pain, paroxysmal pain, and mechanical dynamic allodynia.

AB - Neutrophils are well known for their role in infection and inflammatory disease and are first responders at sites of infection or injury. Platelets have an established role in hemostasis and thrombosis and are first responders at sites of vascular damage. However, neutrophils are increasingly recognized for their role in thrombosis, while the immunemodulatory properties of platelets are being increasingly studied. Platelets and neutrophils interact during infection, inflammation and thrombosis and modulate each other's functions. This review will discuss the consequences of platelet-neutrophil interactions in infection, thrombosis, atherosclerosis and tissue injury and repair.

AB - Three-dimensional cultures of primary epithelial cells including organoids, enteroids and epithelial spheroids have become increasingly popular for studies of gastrointestinal development, mucosal immunology and epithelial infection. However, little is known about the behavior of these complex cultures in their three-dimensional culture matrix. Therefore, we performed extended time-lapse imaging analysis (up to 4 days) of human gastric epithelial spheroids generated from adult tissue samples in order to visualize the dynamics of the spheroids in detail. Human gastric epithelial spheroids cultured in our laboratory grew to an average diameter of 443.9 +/- 34.6 MUm after 12 days, with the largest spheroids reaching diameters of >1000 MUm. Live imaging analysis revealed that spheroid growth was associated with cyclic rupture of the epithelial shell at a frequency of 0.32 +/- 0.1/day, which led to the release of luminal contents. Spheroid rupture usually resulted in an initial collapse, followed by spontaneous re formation of the spheres. Moreover, spheroids frequently rotated around their axes within the Matrigel matrix, possibly propelled by basolateral pseudopodia like formations of the epithelial cells. Interestingly, adjacent spheroids occasionally underwent luminal fusion, as visualized by injection of individual spheroids with FITC-Dextran (4 kDa). In summary, our analysis revealed unexpected dynamics in human gastric spheroids that challenge our current view of cultured epithelia as static entities and that may need to be considered when performing spheroid infection experiments.

AB - Tuberculosis (TB) is a crucial public health problem with prevalence of multidrug resistant (MDR) rising. An accurate TB biomarker is urgently needed to monitor the response to treatment in patients with MDR tuberculosis. To analyze interaction between selected MDR-TB purified protein and immune cells, dendritic cells from MDR-TB patients and healthy subjects were stimulated by 55KDa protein fractions (Rv0147). The purified proteins identified by proteomic techniques (two dimensional gel electrophoresis, mass spectrometry) and peptide sequences are known to bind a MHC class I alleles which are extracted from the Immune Epitope Database and Analysis Resource database ( www.iedb.org ). T cells were isolated from PBMC by negative selection and cells were cultured in RPMI-1640 at 37 degrees C and 5% CO2. Cell culture was assayed for cytokine IL-10 and INF-gamma by ELISA. We found that INF-gamma production was significantly (335 +/- 35.5 pg/ml, P ? 0.05) upregulated after protein candidate (Rv0147) stimulation by dendritic cells from MDR-TB patients, whereas IL-10 production was greatly reduced compared with production in healthy subjects (212 +/- 9.94 pg/ml, P ? 0.05). In fact, the purified protein, Rv0147, stimulated dendritic cells from MDR TB patients, failed to produce IL-10 and directly stimulates INF-gamma production by T cells. These results suggest that the purified protein, Rv0147, may stimulate Th1 type protective cytokine response in MDR-TB patients but not in normal subjects. The production of INF-gamma but not IL-10 in the presence of purified protein, Rv0147, may be shifted to Th1 responses in MDR-TB patients and supports its potential as protein vaccine candidates against TB.

Results of a placebo-controlled doubleblind study.] AB - BACKGROUND AND OBJECTIVES: An optimal vitamin and mineral supply may contribute to the enhancement of immune defenses and thus favorably influence the course and intensity of recurrent upper respiratory tract infections (URIs). In the present study the dietary efficacy and benefits of a micronutrient combination in patients with recurrent URIs was evaluated. METHODS: 192 patients with recurrent URIs were enrolled in this randomized, placebo-controlled, double-blind multicenter trial for a study duration of 16 weeks. Efficacy variables were number, intensity and course of URIs (as assessed using a total common cold score [CCS]) and the alterations in micronutrient supply (vitamins C and D3, folic acid and selenium) during the study. RESULTS: In subjects who initially had at least two common cold symptoms (N = 107) the symptoms improved in the active group (AG) significantly more than in the placebo group (PG; DeltaCCS: AG -6.9 +/- 4.8; PG 5.4 +/- 4.5; p = 0.034). In patients with initially severe common cold (CC) episodes the symptoms improved in the AG to a statistically significant extent (DeltaCCS: AG -93.8%, PG -91.2%, p = 0.043). In the age group below 45 years significantly fewer AG than PG patients were absent from their job during the second or third CC episode (AG: 14.3%, PG: 47.8%, p = 0.038). Patients with vitamin-D deficiency and/or insufficient vitamin-C supply reported significantly fewer CC episodes in AG than in PG. In the course of the trial, in AG vs. PG the serum vitamin C, folic acid and selenium levels increased (p ? 0.001). The concentration of 25(OH)D3 decreased in both groups, but less so in the AG (AG 8.8%; PG -14%; p = 0.001). CONCLUSION: Study results show the efficacy of a nutritional medical treatment with a special micronutrient combination in patients susceptible to infections and suffering from recurrent respiratory tract infections.

AB - PURPOSE: Short-stem hip arthroplasty (SHA) was designed to preserve bone stock and provide an improved load transfer. To gain more evidence regarding the load transfer, this review analysed the periprosthetic bone remodelling of SHA in comparison to standard hip arthroplasty (THA). METHODS: PubMed and ScienceDirect were screened to extract dual-energy X-ray absorptiometry (DXA) studies evaluating the periprosthetic bone remodelling of SHA and two proven THA designs. From the studies included, the postoperative change in periprosthetic bone mineral density (BMD) after one year and the trend over two years was determined. RESULTS: Fifteen studies with four SHAs (CFP, Metha, Nanos, Fitmore) and two THAs (CLS and Bicontact) designs were included. All SHA and THA stems revealed an initial decrease at the calcar and major trochanter (Gruen 1 and 7) with the Metha, Nanos and Fitmore showing a smaller and more balanced remodelling compared to THA. The pattern after one year and the trend over two years argue for a methaphyseal anchorage of the Metha and Nanos, whereas the Fitmore and CFP seem to anchor metha-diaphyseal. Clearly different pattern of bone remodelling were observed between all four SHAs. CONCLUSIONS: Periprosthetic bone remodelling is also present in SHA, with the main bone reduction observed proximally. However, certain SHA stems show a more balanced remodelling compared to THA, arguing for a favourable load transfer. Also, the femoral length where bone remodelling occurs is clearly shorter in SHA. As distinctively different pattern between the SHA designs were observed, they should not be judged as a single implant group.

AB - During the transition period, fatty liver syndrome may be caused in cows undergo negative energy balance, ketosis or hypocalcemia, retained placenta or mastitis problems. During the transition stage, movement of non-esterified fatty acids (NEFA) increases into blood which declines the hepatic metabolism or reproduction and consequently, lactation performance of dairy cows deteriorates. Most of studies documented that, choline is an essential nutrient which plays a key role to decrease fatty liver, NEFA proportion, improve synthesis of phosphatidylcholine, maintain lactation or physiological function and work as anti-oxidant in the transition period of dairy cows. Also, it has a role in the regulation of homocysteine absorption through betaine metabolite which significantly improves plasma alpha-tocopherol and interaction among choline, methionine and vitamin E. Many studies reported that, supplementation of rumen protected form of choline during transition time is a sustainable method as rumen protected choline (RPC) perform diverse functions like, increase glucose level or energy balance, fertility or milk production, methyl group metabolism, or signaling of cell methionine expansion or methylation reactions, neurotransmitter synthesis or betaine methylation, increase transport of lipids or lipoproteins efficiency and reduce NEFA or triacylglycerol, clinical or sub clinical mastitis and general morbidity in the transition dairy cows. The purpose of this review is that to elucidate the choline importance and functions in the transition period of dairy cows and deal all morbidity during transition or lactation period. Furthermore, further work is needed to conduct more studies on RPC requirements in dairy cows ration under different feeding conditions and also to elucidate the genetic and molecular mechanisms of choline in ruminants industry. PMID- 29178048 TI - [Daily ailments among healthy, middle-aged adults - Situation report and explanatory approaches]. AB - HEADING: Background: Physical performance steadily declines with increasing age even among healthy adults. METHODS: A sport scientific screening-battery was used to determine the relationship between physical performance - that is endurance, strength, coordination, flexibility - and typical daily ailments as measured by a questionnaire among 222 healthy, middle-aged women and men. Cardiopulmonary performance was estimated by a 2-km walking test. RESULTS: Cardiopulmonary performance declined significantly as a result of increasing age and increasing body-mass index. 44% of men and 29% of women reached substandard values when compared to norm tables. Daily ailments such as "Problems while climbing stairs" or "Breathing difficulty" showed a strong correlation to the estimated cardiopulmonary performance. In contrast, they were less influenced by strength or flexibility. The subjects were oblivious of the relationship between the decreased performance of the cardiovascular system and daily ailments. CONCLUSION: Performing a simple screening-battery may be a good chance to promote the participation of middle-aged and non-athletic people in an adequate and health oriented sports program.

AB - We studied the effect of moderate heat stress (30oC) and muscarinic cholinergic receptor agonists arecoline and pilocarpine on sensitivity of the behavior of the nematode Caenorhabditis elegans of N2 line to the action of the agonist of nicotinic cholinergic receptor agonist levamisole. Heat stress and muscarinic cholinergic receptor agonists increased the sensitivity of swimming induced by mechanical stimulation to levamisole (32-64 MUM), which manifested in dyscoordination of locomotor muscles during swimming and complete loss of ability to swim. Combined exposure to heat stress and muscarinic cholinergic receptor agonists revealed their synergism in the influence on sensitivity of swimming behavior to levamisole: heating to 30oC potentiated the effect of arecoline and arecoline potentiated the effect of heat stress. It is assumed, that the effect of heat stress on the sensitivity of nicotinic receptors is mediated by its effect on muscarinic receptors. PMID- 29178049 TI - AT1 receptor blockage impairs NF-kappaB activation mediated by thyroid hormone in cardiomyocytes. AB - We have previously demonstrated that calcium-binding protein S100A8 and myeloid differentiation factor-88 (MyD88) are important mediators of nuclear transcription factor kappa-B (NF-kappaB) activation in cardiomyocytes and that signalling molecules are involved in the hypertrophic response that is stimulated by thyroid hormones (TH). Angiotensin II (Ang II), the main active peptide of the renin-angiotensin system (RAS), binds to type 1 Ang II receptor (AT1R) and subsequently promotes cardiac hypertrophy and the inflammatory response with NF kappaB activation underlying the cardiovascular effects. Considering the amount of evidence that RAS is an important mediator of TH actions on the cardiovascular system, we aimed to investigate whether cardiac expression of NF-kappaB and upstream associated molecules could be altered in hyperthyroidism, as well as whether AT1R could mediate the effects of TH on cardiac tissue and in cardiomyocytes in culture. Wistar rats were subjected to hyperthyroidism with or without the AT1R blocker losartan. The TH serum levels, haemodynamic parameters and cardiac mass were assessed to confirm the hyperthyroid status. The S100A8, MyD88 and nuclear NF-kappaB expression levels were increased in the hearts of the hyperthyroid rats, and the losartan treatment attenuated these TH effects. In addition, the cultured cardiomyocytes that had been stimulated with losartan exhibited blunted S100A8 upregulation and NF-kappaB activation compared with the TH-treated cells. Together, our results suggest that AT1R participates in TH induced cardiac hypertrophy partly by mediating S100A8, MyD88 and NF-kappaB activation via TH. These findings indicate the important crosstalk between TH and RAS, highlighting the participation of AT1R in the triggered mechanisms of TH that contribute to the cardiac hypertrophy response. PMID- 29178051 TI - Behavior Disorders Caused by Perinatal Hypoxia in Juvenile Rats and Their Correction with GABA Derivative. AB - We studied the effects of acute normobaric hypoxia on postnatal day 2 (model of preterm pregnancy) on reflex activity and behavior of juvenile male Wistar rats and the possibility of correction of behavioral deficit by administration of GABA derivative Salifen after hypoxia. It is shown, that perinatal hypoxia impaired righting reflex and forelimb grip strength and increased motor activity in juvenile male rats. Administration of Salifen for 14 days in a dose of 15 mg/kg improved reflex activity and behavior of rats, which indicates the prospect of further study of the therapeutic efficacy of this drug on models of neonatal encephalopathy. PMID- 29178052 TI - Prospect of Using Cell Product for the Therapy of Skin Defects in Diabetes Mellitus. AB - The effectiveness of autologous cell product in the therapy of skin burn wounds was studied in C57B1/6 male mice against the background of streptozotocin-induced diabetes mellitus. In animals with and without modeled diabetes mellitus, significant decrease in skin defect area was observed after single administration of the cell product (bone marrow multipotent mesenchymal stromal cells, fibroblasts or media conditioned by these cells). PMID- 29178053 TI - Autosomal Recessive Agammaglobulinemia Due to a Homozygous Mutation in PIK3R1. AB - The role of class IA phosphoinositide 3 kinases (PI3Ks) in immune function and regulation continues to expand with the identification of greater numbers of genetic variants. This case report is the second reported case of a homozygous premature stop codon within the PIK3R1 gene leading to autosomal recessive agammaglobulinemia. The proband, born to consanguineous parents, presented at 10 months of age with a history of oropharyngeal petechiae and bleeding from the mouth, gums, and tear ducts. Initial investigations revealed thrombocytopenia, neutropenia and the absence of B cells. Further genetic testing via a custom next generation sequencing panel confirmed the presence of a homozygous mutation in PIK3R1, c.901 C>T, a premature stop codon at amino acid position 301. Given their many roles in immune regulation, recessive mutations in the PlK3R1 gene should be considered in infants presenting with hypogammaglobulinemia or agammaglobulinemia, particularly in the setting of parental consanguinity. PMID- 29178054 TI - Enhancing Carbohydrate Productivity of Chlorella sp. AE10 in Semi-continuous Cultivation and Unraveling the Mechanism by Flow Cytometry. AB - Accumulated carbohydrate in microalgae is promising feedstock for bioethanol fermentation. Selection of suitable cultivation conditions in semi-continuous cultivation is critical to achieve a high carbohydrate productivity. In the current study, the effects of macro-nutrient (nitrogen, phosphorus, and sulfur) limitations and light intensity were evaluated for the carbohydrate accumulations of Chlorella sp. AE10 under 10% CO2 conditions. It was shown that nitrogen limitation and high light intensity were effective for improving carbohydrate productivity. The average carbohydrate and biomass productivity in semi continuous cultivation with 1/4 N medium and 1000 MUmol photons m-2 s-1 was 0.673 and 0.93 g L-1 day-1, respectively. Sulfur and phosphorus limitations could improve the carbohydrate content but they could not enhance the carbohydrate productivity. The cell cycle progression and chlorophyll a were investigated using flow cytometry (FCM). The results showed that macro-nutrient limitation and high light intensity indeed influenced cell cycle progression and led to the formation of polyploid cells along with the carbohydrate accumulation in a certain range. FCM was rapid and accurate method to investigate the operation conditions why 1/4 N, 2 days as a cycle, and high light intensity were optimal ones. In addition, the remaining high level of photosynthesis activity was also important for achieving a high carbohydrate productivity. Dynamic tracking of carbohydrate accumulation is helpful for establishment of a semi-continuous cultivation for enhancing carbohydrate productivity in microalgae. PMID- 29178055 TI - Solid-State Treatment of Castor Cake Employing the Enzymatic Cocktail Produced from Pleurotus djamor Fungi. AB - In this work, the enzymatic cocktail produced by Pleurotus djamor fungi extracted at pH of 4.8 and 5.3 was employed for castor cake solid-state treatment. Proximal, X-ray powder diffraction and scanning electron microscopy analysis of the pristine castor cake were carried out. First, Pleurotus djamor stain was inoculated in castor cake for the enzymatic production and the enzymatic activity was determined. The maximum enzymatic activity was identified at days 14 (65.9 UI/gss) and 11 (140.3 UI/gss) for the enzymatic cocktail obtained at pH 5.3 and 4.8, respectively. Then, the enzymatic cocktail obtained at the highest enzymatic activity days was employed directly over castor cake. Lignin was degraded throughout incubation time achieving a 47 and 45% decrease for the cocktail produced at pH 4.8 and 5.3, correspondingly. These results were corroborated by the SEM and XRD analysis where a higher porosity and xylan degradation were perceived throughout the enzymatic treatment. PMID- 29178056 TI - Evaluation of Octyl-beta-D-Glucopyranoside (OGP) for Cytotoxic, Hemolytic, Thrombolytic, and Antibacterial Activity. AB - The current study indicates that octyl-beta-D-glucopyranoside (OGP) as a detergent which has the ability to make the lipid layer stiff. OGP was subjected for toxicity studies and in vitro cytotoxicty assays on cancerous HeLa and non cancerous myoblasts H9c2 cell lines. Test against aquatic organisms were carried out in Artemia salina and LC50 values were calculated. Hemolytic activity tested for blood bio-compalibity showed hemolysis rate of 10-16%, followed by thrombolytic activity to burst the clots in blood. Also, the samples showed good lysis when compared to the standard streptokinase. Furthermore, alpha-amylase activity has been carried out to check the inhibition of alpha-amylase by the OGP. Finally, antibacterial activity has been tested against four different pathogens and their MIC values have been calculated. PMID- 29178057 TI - Existence of the passage to the limit of an inviscid fluid. AB - In the dynamics of a viscous fluid, the case of vanishing kinematic viscosity is actually equivalent to the Reynolds number tending to infinity. Hence, in the limit of vanishing viscosity the fluid flow is essentially turbulent. On the other hand, the Euler equation, which is conventionally adopted for the description of the flow of an inviscid fluid, does not possess proper turbulent behaviour. This raises the question of the existence of the passage to the limit of an inviscid fluid for real low-viscosity fluids. To address this question, one should employ the theory of turbulent boundary layer near an inflexible boundary (e.g., rigid wall). On the basis of this theory, one can see how the solutions to the Euler equation become relevant for the description of the flow of low viscosity fluids, and obtain the small parameter quantifying accuracy of this description for real fluids. PMID- 29178058 TI - Interaction of soil pH and phosphorus efficacy: Long-term effects of P fertilizer and lime applications on wheat, barley, and sugar beet. AB - Phosphorus (P), a plant macronutrient, must be adequately supplied for crop growth. In Germany, many soils are high in plant-available P; specifically in arable farming, P fertilizer application has been reduced or even omitted in the last decade. Therefore, it is important to understand how long these soils can support sustainable crop production, and what concentrations of soil P are required for it. We analyzed a 36-year long-term field experiment regarding the effects of different P application and liming rates on plant growth and soil P concentrations with a crop rotation of sugar beet, wheat, and barley. Sugar beet reacted to low soil P and low soil pH levels more sensitively than wheat, which was not significantly affected by the long-term omitted P application. All three crop species showed adequate growth at soil P levels lower than the currently recommended levels, if low soil pH was optimized by liming. The increase in efficacy of soil and fertilizer P by reduced P application rates therefore requires the adaptation of the soil pH to a soil type-specific optimal level.

AB - Functional Land Management (FLM) is proposed as an integrator for sustainability policies and assesses the functional capacity of the soil and land to deliver primary productivity, water purification and regulation, carbon cycling and storage, habitat for biodiversity and recycling of nutrients. This paper presents the catchment challenge as a method to bridge the gap between science, stakeholders and policy for the effective management of soils to deliver these functions. Two challenges were completed by a wide range of stakeholders focused around a physical catchment model-(1) to design an optimised catchment based on soil function targets, (2) identify gaps to implementation of the proposed design. In challenge 1, a high level of consensus between different stakeholders emerged on soil and management measures to be implemented to achieve soil function targets. Key gaps including knowledge, a mix of market and voluntary incentives and mandatory measures were identified in challenge 2. PMID- 29178061 TI - A framework of connections between soil and people can help improve sustainability of the food system and soil functions. AB - Globally soil quality and food security continue to decrease indicating that agriculture and the food system need to adapt. Improving connection to the soil by knowledge exchange can help achieve this. We propose a framework of three types of connections that allow the targeting of appropriate messages to different groups of people. Direct connection by, for example, handling soil develops soil awareness for management that can be fostered by farmers joining groups on soil-focused farming such as organic farming or no-till. Indirect connections between soil, food and ecosystem services can inform food choices and environmental awareness in the public and can be promoted by, for example, gardening, education and art. Temporal connection revealed from past usage of soil helps to bring awareness to policy workers of the need for the long-term preservation of soil quality for environmental conservation. The understanding of indirect and temporal connections can be helped by comparing them with the operations of the networks of soil organisms and porosity that sustain soil fertility and soil functions. PMID- 29178062 TI - AIM2 Inflammasome Is Critical for dsDNA-Induced IL-1beta Secretion in Human Dental Pulp Cells. AB - The AIM2 inflammasome pathway has been determined to play an important role in cellular immune defense against bacterial and viral infections; however, its function and regulatory mechanism in human dental pulp cells (HDPCs) during pulpitis remains poorly understood. In this study, we explored whether the AIM2 inflammasome pathway was activated in HDPCs in response to dsDNA and defined its role in regulating IL-1beta secretion. We demonstrated that stimulation with IFN gamma and cytoplasmic DNA significantly activated the AIM2 inflammasome and increased IL-1beta secretion in HDPCs. Moreover, AIM2 overexpression significantly up-regulated both cleaved Caspase-1 expression and IL-1beta release in HDPCs, while suppression of ASC and Caspase-1 resulted in down-regulation of cleaved Caspase-1 and IL-1beta secretion. These results suggest that Caspase-1 dependent IL-1beta processing and secretion require the AIM2 inflammasome pathway in HDPCs and that the AIM2 inflammasome pathway is critical for regulation of the dental pulp immune response. PMID- 29178063 TI - Evaluation of the performance of three tenodesis techniques for the treatment of scapholunate instability: flexion-extension and radial-ulnar deviation. AB - Chronic scapholunate ligament (SL) injuries are difficult to treat and can lead to wrist dysfunction. Whilst several tendon reconstruction techniques have been employed in the management of SL instability, SL gap reappearance after surgery has been reported. Using a finite element model and cadaveric study data, we investigated the performance of the Corella, scapholunate axis (SLAM) and modified Brunelli tenodesis (MBT) techniques. Scapholunate dorsal and volar gap and angle were obtained following virtual surgery undertaken using each of the three reconstruction methods with the wrist positioned in flexion, extension, ulnar deviation and radial deviation, in addition to the ulnar-deviated clenched fist and neutral positions. From the study, it was found that, following simulated scapholunate interosseous ligament rupture, the Corella technique was better able to restore the SL gap and angle close to the intact ligament for all wrist positions investigated, followed by SLAM and MBT. The results suggest that for the tendon reconstruction techniques, the use of multiple junction points between scaphoid and lunate may be of benefit. Graphical abstract The use of multiple junction points between scaphoid and lunate may be of benefit for tendon reconstruction techniques.

AB - Multi-spectral imaging (MSI) produces a sequence of spectral images to capture the inner structure of different species, which was recently introduced into ocular disease diagnosis. However, the quality of MSI images can be significantly degraded by motion blur caused by the inevitable saccades and exposure time required for maintaining a sufficiently high signal-to-noise ratio. This degradation may confuse an ophthalmologist, reduce the examination quality, or defeat various image analysis algorithms. We propose an early work specially on deblurring sequential MSI images, which is distinguished from many of the current image deblurring techniques by resolving the blur kernel simultaneously for all the images in an MSI sequence. It is accomplished by incorporating several a priori constraints including the sharpness of the latent clear image, the spatial and temporal smoothness of the blur kernel and the similarity between temporally neighboring images in MSI sequence. Specifically, we model the similarity between MSI images with mutual information considering the different wavelengths used for capturing different images in MSI sequence. The optimization of the proposed approach is based on a multi-scale framework and stepwise optimization strategy. Experimental results from 22 MSI sequences validate that our approach outperforms several state-of-the-art techniques in natural image deblurring.

AB - Mitochondria are one of the dominant drivers for producing cellular energy to meet a large number of biological functions, of which the mitochondrial DNA (mtDNA) is the control center of energetic driving force and the dominant driver of mitochondrial molecular diversification. mtDNA transcription generates the necessary RNAs to regulate the extent and nature of mtRNA post-transcriptional modifications and the activity of nucleus-encoded enzymes. With a special focus on mtDNA, the current volume aims to overview the biology and structures of mtDNA, regulatory roles of mtDNA in lung diseases, or involvement of mtDNA in metabolism. We explore the significance of mtDNA sequencing, methylation, stability, and mutation in the pathogenesis of the diseases. Molecular mechanisms by which mtDNA contribute to the regulation of mitochondrial homeostasis and drug resistance are also discussed. We also point out the importance of mitochondrial ribosome, single cell biology, and gene editing in the understanding of the development of mitochondrial dysfunction in lung disease. PMID- 29178066 TI - Mitochondrial DNA in Lung Cancer. AB - Mitochondrial DNA (mtDNA) variations are increasingly discovered and expected to be potential biomarkers to monitor severity, duration, stage, response to therapy, and prognosis in patients with lung cancer. The present article illustrates alterations of mtDNA in lung cancer, including alterations of mtDNA copy number and sequence mutations, as well as their possible mechanisms for carcinogenesis and development of lung cancer. The clear and comprehensive relationships between mtDNA variations and lung cancer are to be further confirmed to benefit effective strategies for lung cancer diagnosis and therapy. PMID- 29178067 TI - Approach, Application, and Bioethics of mtDNA Sequencing in Cancer. AB - Mitochondrial DNA (mtDNA) is more vulnerable to mutations and associated with many solid tumors. Through mtDNA sequencing, we can find useful information on the mutations implicated in diseases and can better define the impact of mitochondrial dysfunction on the process of carcinogenesis. In current article, we will discuss the current approaches of mtDNA sequencing and the challenges we should overcome, their applications in various cancers, and the potential bioethics problems we should face in the application of mtDNA sequencing in clinical diagnosis and treatment. PMID- 29178068 TI - Roles of Mitochondrial DNA Signaling in Immune Responses. AB - Mitochondrial DNA (mtDNA) plays an important role in immune responses during the evolution. The present chapter systemically describes its role on immune-related diseases and its interaction on immune responses. It is important to explore the main function and mechanisms of mtDNA in immune responses by which mtDNA regulates the signaling pathways of Toll-like receptor 9, autophagy, and STING. There are potentials to discover therapeutic targets of mtDNA in immune diseases and inflammation. It will be more exciting if the CRISPR-Cas9 method can be applied for mtDNA gene editing to cure diseases and provide a novel insight of mtDNA in immune responses as well as new therapies. PMID- 29178069 TI - Mitochondrial DNA in Telocytes. AB - Telocyte (TC) is a new identified interstitial cell type with a small nuclear and one or several long and thin prolongations with enlargements on them. They were found in many mammals including humans, mouse, rats, dogs, and monkeys and play vital roles in many physiological and pathological conditions. The ultrastructure of mitochondria was observed in TCs, and the alterations were found in TCs from inflammatory ureter tissue. MtDNA is associated with mitochondria normal functions and involved in physiological and pathological processes. However, mitochondria and mtDNA in TCs were not investigated deeply. This review will introduce the origin, distribution, morphology, and functions of TCs and the distribution and functions of TC mitochondria in order to improve a better understanding of the potential functions of mtDNA in TCs. PMID- 29178070 TI - Roles of Mitochondrial DNA in Energy Metabolism. AB - Mitochondria are independent double-membrane organelles responsible for energy production, specifically by completing oxidative phosphorylation. Mitochondria are essential to regulate energy metabolism, signaling pathways, and cell death. Mitochondrial DNA (mtDNA) can be altered by metabolic disorders, oxidative stress, or inflammation in the progression and development of various diseases. In this chapter, we overview the role of mtDNA in energy metabolism and the diseases that are associated with mtDNA abnormality, with a special focus on the major factors which regulate the mechanism of mtDNA in metabolism. PMID- 29178071 TI - The Role of DNA Repair in Maintaining Mitochondrial DNA Stability. AB - Mitochondria are vital double-membrane organelles that act as a "powerhouse" inside the cell and have essential roles to maintain cellular functions, e.g., ATP production, iron-sulfur synthesis metabolism, and steroid synthesis. An important difference with other organelles is that they contain their own mitochondrial DNA (mtDNA). Such powerful organelles are also sensitive to both endogenous and exogenous factors that can cause lesions to their structural components and their mtDNA, resulting in gene mutations and eventually leading to diseases. In this review, we will mainly focus on mammalian mitochondrial DNA repair pathways that safeguard mitochondrial DNA integrity and several important factors involved in the repair process, especially on an essential pathway, base excision repair. We eagerly anticipate to explore more methods to treat related diseases by constantly groping for these complexes and precise repair mechanisms. PMID- 29178072 TI - Is Mitochondrial Cell Fragility a Cell Weakness? AB - Mitochondrial dysfunction has historically been linked to the cessation of cell function and ageing. Downstream effects such as reduced calcium buffering capacity, elevated levels of reactive oxygen species, and alterations in adenosine-5'-triphosphate are linked to a wide variety of pathological diseases. The importance of the mitochondria has increasingly been highlighted due to its potential as a therapeutic target for drug intervention and cell elimination in cancer. In addition, due to its origin, drugs targeting bacteria are required to be thoroughly tested prior to administration to prevent toxicity for the mitochondria. In this chapter, we will discuss a variety of factors that could influence mitochondrial dysfunction and highlight potential solutions to these. A comprehensive understanding regarding the mechanisms underlying mitochondrial dysfunction could aid in developing future therapeutic targets in multiple pathologies such as cancer and liver diseases. PMID- 29178073 TI - Mitochondrial DNA Methylation and Related Disease. AB - Most researchers focused on methylation of genomic DNA, while methylation of mitochondrial DNA (mtDNA) is rarely tauched, and there is still controversy about the existence of mtDNA methylation. The study of cytosine methylation in mtDNA is limited. The mtDNA was recently found to exist CpG hypomethylation, and more studies provided evidence that mtDNA methylation plays an important role in mitochondrial gene regulation. In present review, we will overview recent studies of mitochondrial DNA methylation and potential influencing factors in diseases that are involved in mtDNA methylation. Thus, the further studies on mtDNA methylation will provide more evidence to explain the mechanism of mtDNA methylation and an advantageous approach for human clinical diagnosis and prevention. PMID- 29178074 TI - Beyond Deubiquitylation: USP30-Mediated Regulation of Mitochondrial Homeostasis. AB - Mutations or sequence aberrations in the Parkin gene are among the most common causes of autosomal recessive Parkinson's disorder (PD). Parkin, a cytoplasmic E3 ubiquitin ligase, is involved in mitochondrial quality control pathways, including mitochondrial fission and mitophagy by autophagy-related genes. Parkin mediates the covalent addition of ubiquitin (Ub) chains to Lys 6, Lys 11, and Lys 63 on diverse mitochondrial-related target proteins. USP30, a mitochondrial deubiquitinase, promotes mitochondrial fusion by mediating the deubiquitination of ubiquitylated forms of mitofusins, such as Mfn1 and Mfn2. USP30 preferentially mediates the removal of Ub chains from Lys 6 and Lys 11 on mitochondria-derived proteins. USP30 mediates the removal of the ubiquitin chains added by Parkin. It was demonstrated that overexpression of USP30 triggers the mitochondrial dynamic signaling toward elevated fusion and reduced fission and halts mitochondrial clearance via mitophagy. Although mounting lines of evidences reveal the pivotal role of Parkin in mitochondrial quality control pathways, the crucial role of deubiquitinases including the USP30 deubiquitinase is emerging. Herein, we review briefly the role of USP30 in the dynamic networks of mitochondrial quality control and its physiological implications. PMID- 29178075 TI - Metabolic Regulation in Mitochondria and Drug Resistance. AB - Mitochondria are generally considered as a powerhouse in a cell where the majority of the cellular ATP and metabolite productions occur. Metabolic rewiring and reprogramming may be initiated and regulated by mitochondrial enzymes. The hypothesis that cellular metabolic rewiring and reprogramming processes may occur as cellular microenvironment is disturbed, resulting in alteration of cell phenotype, such as cancer cells resistant to therapeutics seems to be now acceptable. Cancer metabolic reprogramming regulated by mitochondrial enzymes is now one of the hallmarks of cancer. This chapter provides an overview of cancer metabolism and summarizes progress made in mitochondria-mediated metabolic regulation in cancer drug resistance. PMID- 29178076 TI - Mitochondrial Lon Protease and Cancer. AB - ATP-dependent Lon protease of mitochondrial matrix is encoded by nuclear DNA and highly evolutionarily conserved throughout all organisms, which is involved in the quality control of proteins by selective degradation of misfolded, oxidized, and short-lived regulatory proteins within mitochondrial matrix, maintenance of mitochondrial genome (mtDNA), and folding of mitochondria proteins. Various stimuli such as hypoxia and oxidative and ER stress lead to upregulation of Lon expression. Inhibition of protease activity or downregulation of Lon promotes cancer cell death and enhances sensitivity of cancer cells to anticancer drugs through metabolic reprogramming, thus reducing the viability of cancer cell in tumor microenvironment and epithelial to mesenchymal transition (EMT). Moreover, mitochondrial ATP-dependent Lon protease may serve as a potential biomarker for cancer diagnosis and novel target for the development of anticancer drugs and for predicting of the efficiency and effectiveness of chemotherapy of a variety of cancers. PMID- 29178077 TI - Regulatory Roles of Mitochondrial Ribosome in Lung Diseases and Single Cell Biology. AB - The mitochondria have the most vital processes in eukaryotic cells to produce ATP composed of polypeptides that are produced via ribosomes, as oxidative phosphorylation. Initially, studies regarding human mitochondrial ribosomes were performed in the model system, bovine mitochondrial ribosome, to investigate how ribosomes are biosynthesized and evolved as well as what their structure and function are. Advances in X-ray crystallography have led to dramatic progresses in structural studies of the ribosome. In recent years, there has been a growing interest in the properties of the mitochondrial ribosome. Although one of its main functions is the production of ATP, it was also linked to multiple diseases. A key area that remains unexplored and requires investigation and exploration is how mitochondrial ribosomal RNA (mt-rRNA) variations can affect the mitochondrial ribosomes in developing disease. This review summarizes the structure, elements, functions, and regulatory roles in associated diseases. With the continuous development of technology, studies on the mechanism of mitochondrial ribosome related diseases are crucial, in order to identify methods of prevention and treatment of these disorders. PMID- 29178078 TI - Epithelial Mitochondrial Dysfunction in Lung Disease. AB - Since the twentieth century, scientists have studied the functions and mechanisms of the mitochondria. The mitochondrion plays many important roles in cell functioning and contributes to apoptosis, embryonic and tissue development, aging, etc. Consequently, mitochondrial dysfunction often has a direct impact on health such as aging, tumorigenesis, lung injury and COPD, etc. Recent evidence indicates that the mitochondria could also be a crucial contributor to immunity with functions such as biogenesis, fusion, and fission impacting various areas in initializing immunity. In this review, we will describe both the structure and various functions of the mitochondria with an emphasis on functions such ATP production which is crucial for a multitude of processes such as apoptosis, biosynthesis of Fe/S clusters, steroid synthesis, and, more fundamentally, cell survival. In addition, this review aims to investigate the relationship of epithelial mitochondria and lung disease. Cigarette smoke is known to induce structural and functional mutations in airway epithelial mitochondria often acting as an indicator for diseases such as COPD. Further evidence to support this speculation is the presence of reactive oxygen species (ROS) within cigarette smoke which is a factor in the development of COPD. PMID- 29178079 TI - Significance of Mitochondria DNA Mutations in Diseases. AB - Mitochondria are essential double-membraned cytoplasmic organelles to support aerobic respiration and produce cellular energy by oxidative phosphorylation (OXPHOS). Mitochondrial functions are controlled by mitochondrial (mtDNA) and nuclear genomes (nDNA). Mutations of mtDNA result in mitochondrial dysfunction and multisystem diseases through compromising OXPHOS function directly by a point mutation or a large-scale mtDNA rearrangement. One or more of OXPHOS complexes are impaired and dysfunctional to affect tissues with high energy demands. mtDNA is more susceptible to oxidative damage and has more mutations than nDNA. Unlike diploid nDNA, mtDNA is a multi-copy genome transmitted and maternally inherited through oocyte. The multi-copy nature of mtDNA easily causes the heteroplasmy as a unique aspect of mtDNA, making mitochondrial diseases more complex and heterogeneous. mtDNA-associated mitochondrial dysfunction plays the important role in the development of multisystemic primary mitochondrial disease, neurodegeneration, and cancer. The present article overviews the occurrence of mtDNA mutation, interactions with other factors, and molecular mechanisms of mtDNA-associated diseases.

AB - Structural characterization of fully unfolded proteins is essential for understanding not only protein-folding mechanisms, but also the structures of intrinsically disordered proteins. Because an unfolded protein can assume all possible conformations, statistical descriptions of its structure are most appropriate. For this purpose, we applied Forster resonance energy transfer (FRET) analysis to fully unfolded staphylococcal nuclease. Artificial amino acids labeled with a FRET donor or acceptor were introduced by an amber codon and a four-base codon respectively. Eight double-labeled proteins were prepared, purified, and subjected to FRET analysis in 6 M urea. The observed behavior could be explained by a power law, R = alphaN0.44, where R, and N are the distance and the number of residues between donor and acceptor, and alpha is a coefficient. The index was smaller than the value expected for an excluded-volume random coil, 0.588, indicating that the fully unfolded proteins were more compact than polypeptides in good solvent. The FRET efficiency in the native state did not necessarily correlate to the distance obtained from crystal structure, suggesting that other factors such as the orientation factor made a substantial contribution to FRET.

Different NPs in the form of metallic NPs, dendrimers, polymeric NPs, carbon quantum dots and liposomes have been functionalized and used as platforms for intracellular delivery of biomolecules, drugs, imaging agents and nucleic acids. These NPs are designed to improve the pharmacokinetic properties of the drug, improve their bioavailability and successfully surpass physiological or pathological obstacles in the biological system so that therapeutic efficacy is achieved. In this review I present some of the current approaches used in intracellular delivery systems, with a focus on various stimuli-responsive nanocarriers, including cell-penetrating peptides, to highlight their various biomedical applications. PMID- 29178082 TI - Conversion of microbial rhodopsins: insights into functionally essential elements and rational protein engineering. AB - Technological progress has enabled the successful application of functional conversion to a variety of biological molecules, such as nucleotides and proteins. Such studies have revealed the functionally essential elements of these engineered molecules, which are difficult to characterize at the level of an individual molecule. The functional conversion of biological molecules has also provided a strategy for their rational and atomistic design. The engineered molecules can be used in studies to improve our understanding of their biological functions and to develop protein-based tools. In this review, we introduce the functional conversion of membrane-embedded photoreceptive retinylidene proteins (also called rhodopsins) and discuss these proteins mainly on the basis of results obtained from our own studies. This information provides insights into the molecular mechanism of light-induced protein functions and their use in optogenetics, a technology which involves the use of light to control biological activities.

AB - The laparoscopic surgery for gastrointestinal cancer developed slowly and was at a crossroad of choice at the beginning of the 21st century. However, the team of laparoscopic surgery in Nanfang Hospital was keenly conscious that minimally invasive surgery (MIS) would bring new era to the treatment of gastrointestinal cancer. Therefore, our team went into the exploration of laparoscopic surgery for gastrointestinal cancer: (1) researching a series of anatomical theories for MIS; (2) lucubrating the applicable pattern of fascia and mesentery under laparoscopic view; (3) finding out the precise anatomical landmarks and surgical layers; (4) optimizing the operative strategy. Fortunately, we proposed a safe and simplified strategy of laparoscopic gastrointestinal cancer surgery for Chinese patients with locally advanced stage. Gradually, this strategy was widely adopted by most colleagues in this field. Meanwhile, our team realized the necessity and urgency of education and training for primary care physicians, thus we designed courses based on different laparoscopic levels of the trainees. Also we actively developed the teaching model suitable for the presentation of visual surgery, by taking advantages of mobile network and glasses-free 3D, to break through the limit of time and space in teaching and learning. Besides, we used the internet to create an education system of real-time, opening, practical and efficient academic communication platform, so that more surgeons across the country would be able to synchronize and interact with the experts more instantly and efficiently. All the way, our team hammered at optimizing laparoscopic surgery procedures, along with further perfecting and standardizing training and education system. This article intends to review, summarize and share our experiences in laparoscopic training and education for gastrointestinal surgery, also to remind ourselves of staying true and carry on in this field. PMID- 29178089 TI - [Current status of hereditary gastrointestinal neoplasms]. AB - Gastric cancer and colorectal cancer are two common malignant tumors in digestive tract. 1% to 3% of gastric cancer and 5% to 15% of colorectal cancer are definitely hereditary cancer caused by germline gene mutation. Hereditary gastric cancer includes hereditary diffuse gastric cancer(HDGC) and hereditary intestinal gastric cancer (HIGC). CDH1 gene mutation is the main reason to cause HDGC, so the first degree and the second degree family members of HDGC patients are recommended to receive CDH1 mutation detection, endoscopic examination every year and undergo preventive total gastrectomy. Hereditary colorectal cancer includes hereditary nonpolyposis colorectal cancer (HNPCC, or Lynch syndrome) and familial adenomatous polyposis (FAP). Germline MMR gene mutation detection is the golden standard of the diagnosis of Lynch syndrome. Family members of Lynch syndrome patients are recommended to receive endoscopic examination every year and undergo standard cancer radical operation or total colorectal resection based on individual conditions. FAP is caused by APC gene mutation, so FAP patients are recommended to receive endoscopic examination once or twice every year through their lifetime, while a lot of adenoma occur, resection should be considered. The promotion key of hereditary gastrointestinal neoplasms research is to follow the standard diagnosis and treatment guideline for hereditary gastrointestinal neoplasms and build the clinical and gene information bank of hereditary gastrointestinal neoplasms. The second generation sequencing technique provides favorable research stools in elucidating pathogenesis mechanism of hereditary gastrointestinal neoplasms. PMID- 29178090 TI - [Treatment of primary gastric lymphoma]. AB - Stomach is the most common location of lymphoma in digestive tract, accounting for 50%-60% of gastrointestinal lymphomas. The most common histological types are low malignant mucosa-associated lymphoid tissue (MALT) lymphoma from non-Hodgkin lymphoma (NHL) and diffuse large B-cell and marginal zone B-cell lymphoma (DLBCL) from NHL. Chronic gastritis secondary to Helicobacter pylori(HP) infection has been considered a major predisposing factor for MALT lymphoma. At present, the most widely accepted initial therapy for localized disease is aimed at the eradication of HP using regimens combining antibiotics and proton-pump inhibitors. The irradiation has become the therapy of choice for patients with early stage MALT lymphoma without HP infection or with persistent lymphoma following antibiotic therapy. In all the patients with advanced disease, treatment options include chemotherapy and the use of monoclonal antibodies. Treatment of DLBCL in stomach is based on aggressive poly-chemotherapy that is usually combined with rituximab. The same guidelines followed for nodal aggressive lymphoma can also be applied to gastric lymphoma with aggressive histology as DLBCL. For localized stages (stages I( and II(), these guidelines suggest front-line therapy with 3 to 4 cycles of standard R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) followed by radiotherapy. Advanced stage patients (stage IIII() usually undergo only 6 to 8 cycles of R-CHOP in order to obtain a complete remission rate. Nowadays surgery is limited to rare cases and radiotherapy combined or not with chemotherapy represents an effective therapeutic option ensuring long-term, organ-salvage benefits mainly in aggressive histological types. PMID- 29178091 TI - [Surgical treatment of chronic radiation enteropathy]. AB - Chronic radiation enteropathy(CRE) represents a latent intestinal injury resulting from abdominal-pelvic radiotherapy. Severe complications like refractory bleeding, intestinal obstruction, perforation and fistula may occur during CRE progression. Surgical treatment is the most effective way to handle these complications. Since radiotherapy has become an important and common way to relieve or even cure many malignant tumors, the incidence of severe complications of CRE is likely to rise. Thus the value of surgical treatment in managing severe complications of CRE should gain more attention. Through the literature review combined with our clinical experience, this paper analyzes the preoperative management and surgical treatment of five long-term complications of CRE, including obstruction, enteric fistula, rectovaginal fistula, perforation and bleeding. Also we propose that when managing patients with severe complications of CRE, clinicians should carefully master the surgical indications, consummate perioperative management, design personal surgical plan according to patient's condition and make improving the quality of life of patients the ultimate purpose of surgical treatment for CRE while assuring its safety. PMID- 29178092 TI - [Updates of 2017 ESMO guideline for rectal cancer]. AB - Compared with the 2013 version, the basic strategies of diagnosis and treatment for rectal cancer in the 2017 version guideline remain the same. These strategies include accurate local staging approaches which combines digital rectal examination, endorectal ultrasound (ERUS), and high resolution pelvic MRI, and local recurrence risk grading system which combines tumor location/distance, T staging, N staging, EMVI (extramural vascular invasion) and MRF(mesorectal fascia). And personalized therapeutic principle based on the above local risk grading. Main updates for the 2017 version are as following: (1) x-ray chest film is placed by CT scan for baseline staging, and PET-CT is recommended for patients with extensive EMVI on MRI imaging to exclude further distant metastasis. (2) For local recurrence risk grading, there is one new grade clarified as "intermediate group" added to the 2017 version, which includes patients with very low cT3a/b, levators clear, MRF clear or cT3a/b in mid or high rectum, cN1-2, no EMVI. These patients were classified as "bad group" in the old 2013 version. Accordingly, treatment recommendations for this group changed from preoperative CRT or SCPRT followed by TME surgery to TME surgery alone if good quality of TME assured. Another important notice made in the new guideline is to emphasize the critical role of surgical quality of TME, which should be assessed by a pathologist with help of photography of fresh specimen. In summary, 2017 version of ESMO guideline for rectal cancer is a more personalized and clinically relevant guideline. PMID- 29178093 TI - [Role of nutrition support in the enhanced recovery after surgery for gastrointestinal surgery patients]. AB - Nutrition support therapy can improve the general condition of the patient and is one of the main factors to ensure the success of the operation. Enhanced recovery after surgery (ERAS) improves the recovery following gastrointestinal surgery by reducing postoperative stress response. The application of nutrition support in ERAS includes nutrition risk assessment before surgery and preoperative nutrition treatment for malnutrition. The time to fasting and clear liquid was shortened to 6 h and 2 h before anesthesia induction. Early postoperative recovery of oral feeding can improve the patient's clinical outcome. The application of ERAS enables the development and improvement of clinical nutrition concepts, and deepens the role of nutrition support therapy, which is conducive to the recovery of patients. PMID- 29178094 TI - [Status quo of colorectal cancer screening in Guangzhou community]. AB - The incidence of colorectal cancer (CRC) in China is gradually increasing as a result of the economic development and dietary change. Since it usually takes a long time for precancerous lesions (e.g. adenoma) to develop into cancer, proper cancer screening is useful to discover and to remove these early lesions, while the patients can achieve long-term survival. Hence, developing a well-organized cancer screening system is necessary for the early detection and intervention of potential CRC. Sun Yat-sen University Cancer Center (SYSUCC) has been developing a community-based cancer screening program, using questionnaires and fecal occult blood test to identify the residents with high risks of CRC. These people will be further subjected to colonoscopy and biopsy for the suspected lesions. Among the 1 030 participants in Guangzhou Yuexiu District who received colonoscopy at SYSUCC from January to November in 2015, polyps, inflammation or tumors were found in 361 (35.0%) patients, in whom 13 were colorectal cancers (1.3%), 327 were polyps (31.7%), 239 were adenoma (23.2%), and 140 were prophase adenoma(13.6%). Besides, no significant difference of CRC detection rate between male and female was found (P>0.05), while the detection rate of polyps and prophase adenoma was higher in male than that in female, which also increased significantly with age (P<0.01). We envision such systematic cancer screening extremely useful to enhance the understanding of cancer screening in the public and eventually to realize the early detection and treatment of cancer. PMID- 29178095 TI - [Efficacy analysis of proximally extended resection for locally advanced rectal cancer after neoadjuvant chemoradiotherapy]. AB - OBJECTIVE: To evaluate the short-term outcomes and perioperative safety of proximally extended resection for locally advanced rectal cancer after neoadjuvant chemoradiotherapy. METHODS: From colorectal cancer database in The Sixth Affiliated Hospital of Sun Yat-sen University, a cohort of patients who underwent neoadjuvant chemoradiotherapy(1.8-2.0 Gy per day, 25-28 fractions, concurrent fluorouracil-based chemotherapy) followed by curative sphincter preserving surgery for locally advanced rectal cancer between May 2016 and June 2017 were retrospectively identified. Exclusion criteria were synchronous colon cancer, intraoperatively confirmed distal metastasis, multiple visceral resection, and emergency operation. Thirty-one patients underwent proximal extended resection and two were excluded for incomplete extended resection, then 29 patients were enrolled as the extended group. Using propensity scores matching with 1/1 ration, 29 locally advanced rectal cancer patients who underwent conventional resection after neoadjuvant chemoradiotherapy at the same time were matched as the conventional group. Clinical data of two groups were analyzed, and the baseline characteristics and short-term outcomes were compared using the t test, chi2 test, or Mann-Whitney U test. RESULTS: Two groups were well balanced with respect to the baseline characteristics after propensity score matching. As compared with conventional group, patients in extended group had longer surgical specimen [(18.8+/-5.1) cm vs.(11.6+/-3.4) cm, t=6.314, P=0.000] and longer proximal resection margin [(14.8+/-5.5) cm vs.(8.2+/-3.0) cm, t=5.725, P=0.000], but also had longer total operating time [(322.4+/-100.7) min vs.(254.6+/-70.3) min, t=2.975, P=0.004] and more intraoperative blood loss [100(225) ml vs. 100(50) ml, Z=-2.403, P=0.016]. No significant differences were observed in the length of distal resection margin, ratio of positive resection margin, number of retrieved lymph node, time of analgesic use, time of draining tube use, time to first flatus, time to first oral diet, and postoperative hospital stay. During the perioperative period of 30 days, the morbidity of complication in extended group and conventional group was 17.2%(5/29) and 34.5% (10/29), respectively (P=0.134). CONCLUSION: Proximally extended resection is a radical and safe surgical alternative for locally advanced rectal cancer after neoadjuvant chemoradiotherapy, which can potentially reduce the risk of anastomosis complication. PMID- 29178096 TI - [Risk factors and outcomes of postoperative delirium in colorectal cancer patients over 60 years]. AB - OBJECTIVE: To determine the incidence, risk factors and clinical outcomes of postoperative delirium in colorectal cancer patients over 60 years. METHODS: Consecutive 382 patients older than 60 years undergoing colorectal cancer surgery at Shenzhen Second People's Hospital from June 2013 to June 2016 were recruited prospectively in this study. These patients were evaluated daily after surgery for 7 days by confusion assessment method. Clinical outcomes were compared between patients with and without postoperative delirium, including postoperative complications, length of hospital stay, and mortality within 30 days. Logistic regression analysis was used to identify independent predictors of postoperative delirium. RESULTS: There were 230 male and 152 female patients with median age of 67(range 60 to 92) years. Among them, 213 had colon cancer and 169 had rectal cancer. Postoperative delirium developed in 46(12.0%) patients, and most deliriums (78.3%) were diagnosed within 3 days after surgery. Patients with postoperative delirium had more complications [30.4%(14/46) vs. 17.3%(58/336), P=0.032], higher mortality [6.5%(3/46) vs. 1.8%(6/336), P=0.047], and longer postoperative hospital stay (median 14 days vs. 9 days, P=0.008). Univariate analysis revealed that advanced age, male, higher Charlson comorbidity index, higher American Society of Anesthesiologists Classification, lower preoperative blood albumin concentration, history of psychiatric disease, history of cerebrovascular disease, alcohol abuse, emergent operation, and perioperative blood transfusion were significantly related to the development of postoperative delirium. Logistic regression analysis identified that advanced age (OR=1.06, 95%CI: 1.01 to 1.13), history of psychiatric disease (OR=10.89, 95%CI: 2.73 to 41.59) and perioperative blood transfusion (OR=2.37, 95%CI: 1.11 to 7.32) were independent risk factors of postoperative delirium. CONCLUSIONS: Postoperative delirium is relatively common in elderly patients over 60 years undergoing colorectal cancer surgery. The high morbidity of postoperative complication and mortality associated with postoperative delirium warrant implementation of preoperative risk assessment and postoperative screening protocol for postoperative delirium. Comprehensively preventive strategies should be carried out for high-risk patients, e.g. advanced age, history of psychiatric disease, and perioperative blood transfusion. PMID- 29178097 TI - [Association of early diarrhea and fecal volume with anastomotic leakage after low anterior resection of rectal cancer]. AB - OBJECTIVE: To evaluate the association of early diarrhea and fecal volume with anastomotic leakage after low anterior resection (LAR) of rectal cancer. METHODS: Clinical data of 541 patients with rectal cancer undergoing LAR at The Affiliated Hospital of Guangdong Medical College between January 2007 and January 2017 were analyzed retrospectively. Early postoperative diarrhea was defined as at least one occurrence of more than 50 ml watery stool or at least four times defecation per day within 7 days after surgery. The volume of fecal discharge from the transanal drain was measured at daily intervals for 3 days after surgery. Association of early diarrhea and anastomotic leakage was analyzed using logistic regression model. The accuracy of fecal volume in predicting anastomotic leakage was evaluated using receiver operating characteristics (ROC) curve. RESULTS: There were 319 males and 222 females with mean age of 59.3 years. Early postoperative diarrhea occurred in 99(18.3%) patients, and 41(7.6%) patients developed anastomotic leakage. The incidence of anastomodc leakage in patients with early diarrhea was significantly higher as compared to those without early diarrhea (15.2% vs. 5.9%, P=0.000). Multivariate analysis revealed that early diarrhea (OR=33.940, 95%CI: 8.423 to 89.240) and the distance between the tumor and the anal verge less than 7 cm (OR=13.085, 95%CI: 2.117 to 44.556) were independent risk factors for anastomotic leakage, while the presence of a transanal tube was an independent protective factor (OR=0.474, 95%CI: 0.122 to 0.881). The total fecal volume for 3 days after surgery was calculated in 162 patients with a transanal tube. The median fecal volume was 210 (100 to 4360) ml and 60 (0 to 480) ml in patients with and without anastomotic leakage respectively(P=0.000). ROC curve showed that the cut-off value of fecal volume for anastomotic leakage was 110 ml and the area under the curve was 0.824 with a high sensitivity of 85.7% and specificity of 81.3%. CONCLUSIONS: Early postoperative diarrhea after LAR procedure of rectal cancer may be an early predictor of anastomotic leakage, and fecal volume for 3 days after surgery >=110 ml can accurately predict anastomotic leakage. Active prevention and management of early postoperative diarrhea may reduce the risk of anastomotic leakage. PMID- 29178098 TI - [Evaluation of three-dimensional CT reconstruction on the anatomic variation of inferior mesenteric artery and left colic artery]. AB - OBJECTIVE: To demonstrate the clinical applicability of three-dimensional CT angiography by evaluating the anatomic features and variation of inferior mesenteric artery(IMA) and left colic artery(LCA) in order to provide reference to vessel ligation strategy in laparoscopic rectal cancer surgery. METHODS: Clinical and image data of 123 patients receiving abdominal multislice CT at The Sixth Affiliated Hospital from 2014 to 2015 were retrospectively analyzed. The images were 3D-reconstructed with computer 3D CT angiography and arterial enhancement phase images were chosen for analysis. Linear distances from IMA root to abdominal aortic bifurcation and from LCA at IMA root level to IMA root were measured. Branch types of IMA, coursing pattern of LCA, and association between LCA and inferior mesenteric vein (IMV) site were summarized. RESULTS: Of 123 cases, 80 were males and 43 were females, mean age was (46.8+/-16.6) years, body weight was (57.7+/-10.4) kg, and BMI was (21.3+/-3.6) kg/m2. The average distance from IMA root to abdominal aortic bifurcation was (42.5+/-7.9) mm, and this distance was closely associated with body weight (OR=4.771, 95%CI: 1.398 to 16.283, P=0.013). Longer distance tended to appear in the heavier patients. LCA and sigmoid artery (SA) originating from same single IMA was found in 61(49.6%) cases; LCA and SA forking at same point in 35(28.5%) cases; LCA and SA coursing together and forking afterwards in 24(19.5%) cases, and LCA disappearing in 3(2.4%) cases. In 71(57.7%) patients, LCA ascended medial to the lateral border of left kidney, while in 16(13.0%) patients, LCA arranged below the inferior border of left kidney. When the LCA site was higher and the distance from LCA to IMA root was closer [distance from LCA to IMA root level was (24.2+/-9.9) mm, (30.0+/-15.2) mm and (66.6+/-12.3) mm, F=83.2, P<0.001]. At the level of IMA root, LCA located medial to IMV in 21(17.1%) cases, located just lateral to IMV in 54(43.9%) cases, and located lateral and ascended far away from IMV in 48(39.0%) cases. CONCLUSION: 3D-CT angiography is non-invasive, efficient and accurate in evaluating coursing features and variation of IMA and its branches, which can provide important reference to the surgeons, promising laparoscopic surgery smooth and safe. PMID- 29178099 TI - [Analysis of risk factors on pulmonary infection after D2 lymphadenectomy gastrectomy for gastric cancer]. AB - OBJECTIVE: To explore the risk factors of pulmonary infection after D2 radical gastrectomy of gastric cancer in order to guide clinical measures to reduce the incidence of pulmonary infection. METHODS: Clinical data of 371 patients undergoing D2 radical gastrectomy at Division 2 of Gastrointestinal Cancer Center from October 2014 to October 2016 were collected for retrospective cohort study. Associated risk factors of pulmonary infection after D2 radical gastrectomy of gastric cancer were analyzed. Diagnosis criteria of pulmonary infection: occurrence of new pulmonary rales; new infiltrative change or consolidation in chest by imaging examination; with at least one of the following: temperature >=38.5centi-degree, emergence of new purulent sputum or sputum character change, isolated pathogens from bronchial brush biopsy or tracheal secretion culture. RESULTS: Of 371 patients, 265 were males and 106 were females. The average age was 59.1(22-80) years old. There were 38(10.2%) cases of pulmonary infection after radical resection of gastric cancer. Univariate analysis showed that smoking history, intra-operative blood loss >=200 ml, total gastrectomy, and gastric intubation >=6 d were associated with pulmonary infection after D2 radical gastrectomy (all P<0.05). Six cases quitted smoking 2 weeks before operation with pulmonary infection incidence of 8.1%(6/74), and 16 patients did not quit smoking 2 weeks before operation with pulmonary infection incidence of 21.1%(16/76), and the difference was statistically significant (chi2=4.0387, P=0.0445). Multivariate Logistic regression analysis showed that postoperative gastric intubation >=6 d (OR=4.335, 95%CI: 1.088 to 4.586, P=0.05), smoking history (OR=3.469, 95%CI: 1.056 to 5.252, P=0.043) and intra-operative blood loss >=200 ml (OR=3.931, 95%CI: 1.350 to 10.574, P=0.013) were independent risk factors of pulmonary infection after D2 radical gastrectomy of gastric cancer. CONCLUSION: For gastric cancer patients undergoing D2 radical gastrtectomy with smoking history, greater blood loss during operation and postoperative gastric intubation >=6 d, surgeons must pay attention to the prevention of postoperative pulmonary infection. PMID- 29178100 TI - [Lymph node metastasis regularity and risk factors in 768 cardiac carcinoma patients]. AB - OBJECTIVE: To investigate the regularity of lymph node metastasis in cardiac carcinoma and its risk factors. METHOD: Complete clinicopathological data of 768 cardiac carcinoma patients undergoing radical resection and lymph node dissection were collected. A retrospective cohort study was performed to analyze the distribution of lymph node metastasis (lymph node metastasis rate=number of patients with lymph node metastasis/number of patients with lymph node dissection; lymph node metastasis frequency=number of metastatic lymph node/number of total resected lymph node) and the influence of clinicopathological factors on lymph node metastasis. RESULTS: Of the 768 patients, 599 were male and 169 were female, with mean age of 61(28 to 85) years. According to gastric cancer staging criteria from the American Joint Cancer Association (AJCC) 7th edition in 2010, there was 256 cases in N0 stage, 171 cases in N1 stage, 181 cases in N2 stage, 160 cases in N3 phase; 18 cases in T1 stage, 30 cases in T2 stage, 9 cases in T3 stage, 711 cases in T4 stage. Borrmann type I( was found in 61 cases, type II( in 306 cases, type III( in 358 cases, type IIII( in 43 cases. The histological type was adenocarcinoma in 738 cases and signet ring cell carcinoma in 30 cases. A total of 9 183 lymph nodes were resected during operation for 768 patients with mean 12(0 to 57) nodes per case, while 510 patients were found to have 2 889 metastatic nodes; the lymph node metastasis rate was 66.4%(510/768), and lymph node metastasis frequency was 31.5%(2 889/9 183). Besides, 483 patients were found to have 2 759 metastatic lymph nodes and 8 246 resected lymph nodes in abdominal cavity with lymph node metastasis rate of 62.9%(483/768) and lymph node metastasis frequency of 33.5% (2 759/8 246); 57 patients were found to have 130 metastatic lymph nodes and 937 resected lymph nodes in thoracic cavity with lymph node metastasis rate of 7.4%(57/768) and lymph node metastasis frequency of 13.9%(130/937). Stations with the higher lymph node metastasis rate included paracardiac (left cardia: 38.8%, right cardia: 39.9%), lesser curvature of stomach(41.9%), left gastric artery (46%) and posterior pancreatic (38.5%). A total of 361 patients had resected lymph node number >=12 during operation, while other 407 patients had number <12. Univariate analysis showed that Borrmann type, depth of tumor invasion and resected lymph node number were associated with lymph node metastasis. Lymph node metastasis rates of Borrmann type I(, II(, III( and IIII( patients were 55.7% (34/61), 62.7% (192/306), 73.7% (264/358) and 51.2%(22/43) respectively, and the difference was statistically significant (chi2=18.115, P=0.000). Lymph node metastasis rates of T1, T2, T3, T4 stage patients were 0%(0/18), 30%(9/30), 100%(9/9) and 69.5%(494/711) respectively, and the difference was statistically significant (chi2=63.971, P=0.000). Lymph node metastasis rate of patients with resected lymph node number >=12 was 79.5%(287/361), which was significantly higher than 55.3%(225/407) of those with resected lymph node number <12(chi2=50.496, P=0.000). Multivariate analysis revealed that higher T stage (OR=2.326, 95%CI: 1.758 to 3.078, P=0.000) and resected lymph node number >=12(OR=2.998, 95%CI: 2.142 to 4.195, P=0.000) were independent risk factors of lymph node metastasis. CONCLUSIONS: The lymph node metastasis rate of cardiac carcinoma is quite high. The metastasis occurs mainly in the surrounding of cardia, the small curvature of the stomach, the left artery of stomach and posterior pancreatic. The depth of tumor invasion and the number of lymph node dissection are independent risk factors of lymph node metastasis.

Survival data were obtained by follow-up and the last follow-up time was October 2016. Log-rank test and Cox regression model were used to analyze the risk factors of prognosis and these factors included gender, age, tumor size, degree of differentiation, histological type, Lauren pattern, T stage, N stage, vessel carcinoma embolus, clinical symptom, anemic condition, CA19-9 level, et al. RESULTS: The median age of 90 patients was 35 years old, of whom, 20(22.2%) patients were <=30 years old and 70(77.8%) patients were between 31 and 40 years old. There were 70(77.8%) female patients, 38(42.2%) patients with anemia, 11(12.8%) patients with elevated CA19-9 level and 9(10.0%) patients with family history of gastrointestinal tumors. The mean time of all the patients from presence of symptom to consultation was 8.2 months. Postoperative pathology revealed 65(72.2%) patients with poorly differentiated adenocarcinoma, 6(6.7%) patients with mucinous adenocarcinoma, 9(10%) patients with signet-ring cell carcinoma, and 10(11.1%) patients with papillary-canalicular adencarcinoma. Sixty-nine (76.7%) patients were diagnosed as advanced gastric cancer and 67(74.4%) patients were involved with lymphatic metastasis when they visited our hospital. Univariate analysis showed that gender (P=0.021), tumor size (P=0.001), depth of tumor infiltration (P=0.016), lymphatic metastasis (P=0.000), vessel carcinoma embolus (P=0.001), elevated CA19-9 level (P=0.001), and anemia (0.024) were statistically related with postoperative survival. Multivariate analysis showed that lymphatic metastasis was an independent risk factor of the poor prognosis of young patients (HR:2.774, 95%CI:1.435 to 5.364, P=0.002). CONCLUSIONS: The majority of young gastric cancer cases are female with poorly differentiated adenocarcinoma. Most patients are diagnosed as advanced gastric cancer with lymphatic metastasis when they visit hospital at the first time. The lymphatic metastasis is an independent risk factor of prognosis in young gastric cancer patients. PMID- 29178102 TI - [Value of serum human epithelial growth factor receptor 2 extracellular domain and circulating tumor cells in evaluating therapeutic response in advanced gastric cancer]. AB - OBJECTIVE: To examine the correlation between serum human epithelial growth factor receptor 2 extracellular domain (HER2 ECD) and circulating tumor cells (CTC), as well as the dynamic variation of HER2 ECD and its correlation to the therapeutic efficacy. METHODS: Fifty-three advanced gastric cancer (AGC) patients who treated in Peking University Cancer Hospital and ever enrolled into CTC study (ClinicalTrial gov. ID: NCT01625702) were retrospectively included in this study. INCLUSION CRITERIA: the patients were histologically confirmed as locally advanced or recurrent and/or metastatic adencarcinoma; they received two or more cycles of fluorouracil-based chemotherapy or combination targeted therapy; serum CTC was counted before and after therapy; the clinical response was evaluated every 2 cycles of treatment by the presence of at least one measurable lesion according to RECIST version 1.1 criteria. This study was approved by Ethics Committee of Peking University Cancer Hospital, and informed consents were signed by patients. The sera before and after two cycles of treatment were collected for CTC enumeration and HER2 ECD detection, in which the levels of HER2 ECD were measured by chemiluminescence immunoassays method. The positive threshold value of HER2 ECD and CTC number were >=15 MUg/L and >=3 CTCs/7.5 ml respectively. The progression-free survival (PFS) and overall survival (OS) were compared among different groups using Log-rank tests. RESULTS: In 53 enrolled patients, 39 were histologically identified as negative HER2, 9 as positive HER2 and another 5 cases were unknown. All the patients received fluorouracil-based chemotherapy, and 9 positive HER2 patients received combined anti-HER2 targeted therapy. Before therapy, the median HER2 ECD concentration of 53 cases was 10.45 (8.0 to 83.2) MUg/L. Seven patients exhibited positive HER2 ECD levels, in whom 4 were histologically HER2 positive, but 3 were histologically HER2 negative. The median CTC number of 53 cases was 2 (0 to 668) CTCs/7.5 ml, and the positive rate of CTC was 47.2%(25/53). Following 2 cycles of therapy, a total of 10 histologically HER2 negative patients exhibited positive HER2 ECD levels, in whom 2 also possessed positive HER2 ECD levels, 83.3 MUg/L and 46.9 MUg/L before therapy, and 22.4 MUg/L and 20.4 MUg/L after therapy respectively, whereas another 8 patients (10.3 to 14.5 MUg/L before therapy) acquired the elevated expression of HER2 ECD following therapy (15.1 to 19.5 MUg/L). It seems that the increased level of HER2 ECD after therapy was, though not statistically significant, correlated to low number of CTCs. In histologically HER2 negative patients, pretherapeutic HER2 ECD level (positive vs. negative) was not significantly correlated to PFS (7.6 months vs. 4.4 months, P=0.328) and OS (13.6 months vs. 10.9 months, P=0.679). However, in histologically HER2 positive patients, patients with positive HER2 ECD level before therapy exhibited longer PFS (10.7 months vs. 4.2 months, P=0.025) and OS (16.5 months vs. 8.9 months, P=0.015) compared to those with negative HER2 ECD level. Additionally, CTC number was significantly correlated to prognosis in histologically HER2 negative patients. Patients with positive pretherapeutic CTC number showed longer PFS (5.3 months vs. 3.3 months, P=0.049) and OS (14.3 months vs. 7.6 months, P=0.001) as well. While in histologically HER2 positive patients, CTC number was not obviously correlated to the PFS and OS. In above 8 negative HER2 patients acquiring elevated expression of HER2 ECD following therapy, the increased HER2 ECD level was not correlated to PFS and OS (all P>0.05). In 9 histologically HER2 positive patients, 4 patients who exhibited decreased HER2 ECD level and reduced or constant CTC number had longer PFS (7.5 to 15.3 months) and OS (11.0 to 26.3 months) compared with those 2 patients who suffered from acquired HER2 ECD level following therapy (PFS 3.0 to 4.8 months and OS 7.3 to 8.6 months). CONCLUSIONS: In histologically HER2 positive patients, increased pretherapeutic HER2 ECD level predicts better prognosis. The acquired elevated HER2 ECD level following therapy is correlated to inefficient therapeutic response. The acquirement of elevated HER2 ECD level can also be found in histologically HER2 negative patients, which may be correlated to the corresponding variation of CTC number.

AB - Crohn disease (CD) is a chronic inflammatory disease which progressively affects the digestive tract with unknown etiology. During the disease course, intestinal fibrosis will gradually develop in many CD patients and results in irreversible fibrosis stricture, causing refractory abdominal pain and even intestinal obstruction, and necessitating one or more surgical interventions. Thus far the exact etiology of CD remains unknown. It is believed that genetic, environmental and immunologic factors are involved, which may also predict the development of intestinal fibrosis. Recent studies have found the association of mutations in genes, such as NOD2, ATG16L1, CX3CR1, IL-23R and MMP3 with the fibrogenic phenotype of CD. In addition, serum extracellular matrix molecules, growth factors, miRNAs and microbial antibodies have also been linked to the fibrogenesis in CD patients, however the results of researches were divergent. Therefore it is of significance to explore noninvasive markers of intestinal fibrosis with high sensitivity and specificity, and the high-throughput proteomic technique may be an approach that deserves further investigation. Screening the high-risk patients for the fibrostenotic phenotype of CD by susceptibility genes, and early detection of intestinal fibrosis using noninvasive serum markers, will help improve the treatment outcomes and reduce the surgical rates. The article aims at summarizing the current susceptibility genes and serum markers of intestinal fibrosis in CD.

AB - OBJECTIVE: To investigate the influence of CCL21 on the invasion and metastasis of colorectal cancer (CRC). METHODS: CCL21 over-expressing CRC cell line was constructed by lentivirus infection and CCL21 low-expressing CRC cell line was constructed by lipofection. The effects of CCL21 on the invasion and metastasis of CRC cells and the stem cell-like phenotype were investigated by Transwell migration, invasion assay, wound healing assay and sphere formation assay. RESULTS: Real-time quantitative PCR and western blot confirmed that the expression of CCL21 was up-regulated by lentiviral transfection and down regulated by siRNA liposome transfection. In vitro, Transwell assays showed that the invasion and migration in CCL21 over-expressing CRC cells decreased significantly as compared to those of CCL21 low-expressing cells. In wound healing assay, the CCL21 over-expressing CRC cells showed a significantly lower rate of migration. In addition, the sphere formation rate and density of CCL21 over-expressing CRC cells were lower than those with low-expression of CCL21. CONCLUSION: CCL21 can suppress the migration and invasion of CRC cells and weaken their stem cell-like phenotype.

AB - INTRODUCTION: The Newcastle Stroke-Specific Quality of Life Measure (NEWSQOL) is one of the few specific questionnaires for evaluating the quality of life among patients who have suffered an ischaemic or haemorrhagic stroke. AIMS: To translate and adapt this questionnaire into Spanish and to evaluate its reliability and acceptability. PATIENTS AND METHODS: The original version of the NEWSQOL questionnaire was translated into Spanish. The translation was agreed upon by a team of experts, and was then back-translated into English and sent to the author, who gave her approval of the rendering. This version was later administered to a group of patients in order to evaluate its reliability, acceptability, floor effect and ceiling effect. RESULTS: The process of linguistic adaptation allowed semantic, conceptual and content equivalence to be achieved in the Spanish version of the NEWSQOL. The results obtained in the preliminary analysis show excellent acceptability, an internal consistency index of 0.9 for the whole questionnaire and a good or excellent test-retest agreement for all the domains. No ceiling effect was detected, but a floor effect was observed in the case of the vision and cognition domains. CONCLUSION: The Spanish version of the NEWSQOL questionnaire is reliable for evaluating the quality of life in post-stroke patients, as well as being well accepted. The questionnaire must be used in more broader samples in order to evaluate its validity and sensitivity. PMID- 29178106 TI - [The level of knowledge regarding the concept of brain death among undergraduates at the Universitat de Lleida]. AB - INTRODUCTION: Brain death is a death situation which is diagnosed by means of neurological criteria and is the ideal situation for organ donation, as, thanks to intensive care, the organs maintain their viability. Very few studies have analysed the knowledge that the population has about this situation. AIM: To determine how much university students know about brain death by comparing the results between undergraduates pursuing a degree in medicine and those on other bachelor's degree courses. SUBJECTS AND METHODS: A closed on-line survey was administered to undergraduate students at the Universitat de Lleida about their knowledge regarding the concept of brain death, donor legislation and willingness to donate. RESULTS: The survey was answered by a total of 488 people, 192 (39.3%) from the degree in medicine. Only 164 (33.6%) were males. The mean age was 22.1 +/- 4.4 years. Only 63 (12.9%) respondents defined brain death as death. While 19.1% replied correctly to the question about organ donation legislation, 79.7% said they would be willing to donate their organs. The level of knowledge was significantly higher in the later courses of the degree in medicine, although there was still plenty of room for improvement in this respect. Only 31.7% of sixth-year students had a good idea of the concept of brain death. CONCLUSION: The extent of knowledge about brain death and legislation on organ donation is poor among university students, even in the degree in medicine. It would be advisable to design strategies aimed at improving this knowledge, especially among future healthcare professionals. PMID- 29178107 TI - [A study of the demand for health care in hereditary-metabolic diseases in a Spanish tertiary care hospital]. AB - AIM: To determine the characteristics of the demand for health care in hereditary metabolic diseases in a Spanish tertiary care hospital. PATIENTS AND METHODS: We conducted a retrospective descriptive study involving a review of the epidemiological data, reasons for visiting, diagnoses and complementary studies of the patients treated by a metabolic disease unit over a period of 6 years and 11 months. RESULTS: Altogether 1012 patients were evaluated. There was a predominance of males (52%) and of patients under the age of 1 year (42.09%). 71.44% of them were under 6 years old. Approximately half of the patients (50.3%) came from hospitals (wards, outpatients, neonatology, emergency department, neuropaediatrics and intensive care), followed by the neonatal screening programme (20.36%) and primary care (14.82%). The most frequent reasons for visiting and diagnoses can be seen in their respective tables. CONCLUSIONS: The study of the demand for health care in hereditary-metabolic diseases is useful as a means to detect needs in their field and to try to adapt care to meet them. Medical, scientific and social progress makes it necessary to have an expert in metabolism present in reference clinical units. As members of multidisciplinary teams alongside other specialists, they will contribute towards accomplishing a suitable presumptive diagnosis, diagnosis, management and follow-up. It is necessary to keep them constantly up-to-date and ensure adequate training of new experts in metabolism, since this is the best way to deliver optimal care for those with metabolic illnesses, which are usually rare diseases.

AB - INTRODUCTION: In recent years there has been an increase in the number of endovascular examinations in the study of both cardiovascular and cerebrovascular diseases. One very infrequent complication is neurotoxicity due to contrast, and it must be suspected within the context of a neurological deficit following such examinations in order to be able to diagnose it. CASE REPORT: A 61-year-old male who presented an epileptic attack and later deficit in the left hemisphere following diagnostic arteriography. After ruling out the possibility of an urgent vascular pathology, he was submitted to a magnetic resonance brain scan with the suspicion of this condition. The clinical signs and symptoms were limited to 72 hours with cortisone therapy. CONCLUSIONS: Contrast-induced encephalopathy covers a wide range of clinical features which, in the vast majority of cases, are self limiting to 24-72 hours, and within the context of neuronal damage following contrast infusion. Its prognosis is excellent, and diagnostic suspicion is crucial in its treatment. PMID- 29178110 TI - [42.a Reunion de la Sociedad de Neurofisiologia Clinica de las Comunidades de Valencia y Murcia.

AB - INTRODUCTION: Prepulse inhibition (PPI) of the startle response is an index used to evaluate how the pre-attention system works. PPI is altered in patients with a mental disorder such as schizophrenia and in subjects who are vulnerable to it. Likewise, cocaine users also frequently exhibit psychiatric disorders as schizophrenia. AIM: To know the alterations that cocaine produces on PPI. DEVELOPMENT: A comprehensive review is carried out, covering both clinical and preclinical studies with animal models that have evaluated the effects of cocaine exposure on the PPI paradigm. Underlying neural bases and mechanisms of action are suggested to explain these findings. CONCLUSIONS: Cocaine alters PPI through its action on the dopaminergic system. Acute exposure of cocaine decreases PPI by increasing dopamine, while with chronic use, depending on withdrawal time, PPI can be restored. However, the effects of cocaine on PPI appear to depend on the baseline levels of PPI shown by the individual. Thus, since a deficit in PPI has been associated with a greater vulnerability to developing mental pathologies such as schizophrenia, PPI level in subjects could be considered as a biomarker of psychiatric vulnerability. Therefore, a better understanding of the effect of drugs such as cocaine on PPI may help to understand the development of dual pathology.

AB - Many adolescents with ADHD show antisocial behaviour and low educational achievement. These issues have not been validated in the World Health Organization Eastern Mediterranean Region. The objective of this study was to assess the global functioning and behaviour of children with ADHD growing into adolescence 10 years after initial diagnosis. Parents were interviewed using a structured questionnaire, Conner's Short Version Test and the Children's Global Assessment Scale. Nearly half of our sample had low academic achievement and 36% had no friends. A quarter of the cases were smokers, one admitted abusing drugs and one had attempted suicide. One third of the sample continued to have ADHD symptoms. Adolescents with ADHD had similar school performance and peer relationships to those reported previously, but differences with regard to drug use, suicide and other impulsive behaviour. A follow-up study into adult life using a control group is recommended. PMID- 29178115 TI - Multiplex polymerase chain reaction-based serotype analysis of dengue virus during 2015 dengue outbreak in Pakistan. AB - Dengue is one of the most important arthropod-borne viral diseases. It is endemic in > 125 countries including Pakistan, with a global incidence of 50-200 million. We determined the frequency of different serotypes of dengue virus to highlight its hyperendemicity in Rawalpindi, Pakistan. Between May and October 2015 we analysed the serum samples of 140 patients with a suspicion of dengue, using ELISA and multiplex polymerase chain reaction. One hundred and eight were infected with serotype 2, 16 with serotype 3, 7 with serotype 4 and 3 with serotype 1. Three patients were infected with serotypes 1 and 2, and 1 each with serotypes 1 and 4 and serotypes 2 and 3. Incidence of dengue has increased many fold in the past 50 years and has expanded to areas that were previously free from the disease. Serotype 2 was predominant in our population followed by serotype 3. There is currently no specific treatment for dengue, and vector control and vaccination are the only effective methods to prevent future outbreaks. PMID- 29178116 TI - Third study on WHO MPOWER Tobacco Control Scores in Eastern Mediterranean countries 2011-2015. AB - This study was conducted to quantify the implementation of the MPOWER policies and to assess any possible changes across Eastern Mediterranean Region (EMR) countries. In this comparative cross-sectional study based on 10 categories mentioned in MPOWER report 2015 a checklist was designed. Seven questions were scored from 0-4 and three from 0-3. The 22 EMR countries were ranked and compared by their total score on a scale of 0-37. The highest scores were achieved by Egypt and the Islamic Republic of Iran. Pakistan, Sudan and Yemen showed progress, while Bahrain, Jordan, Kuwait, Oman, and the Syrian Arab Republic had decreased scores. The total score of the EMR countries had decreased compared to 2013. Thus, there remains a need for greater focus on tobacco taxation and smoke free policies to address this retrograde step. PMID- 29178117 TI - Mood and anxiety disorders among adolescent students in Jordan. AB - Mental disorders in adolescents have negative impacts on aspects of health and life that can be reduced by early detection and referral. This study aimed to estimate the prevalence of mood and anxiety disorders and to investigate their association with gender and other socio-demographic factors among adolescent students. A descriptive cross-sectional design was used in this study. A sample of 1103 adolescent students was recruited from schools who completed the first two sections of Patient Health Questionnaire for Adolescents (PHQ-A). The prevalence of any mental disorders was 28.6%. The prevalence of mood and anxiety disorders was 22.4% and 16.3%, respectively. Significant associations were found between mental disorders and gender, age, living status with parents, or mental health status of parents. Further studies are needed to be conducted in Jordan in order to understand the nature and risk factors of mental disorders among adolescents. School and community-based mental health screening, promotion and prevention programmes are recommended to prevent and reduce the prevalence of mental disorders among adolescents. PMID- 29178118 TI - Midwives' educational needs and knowledge about sexually transmittable infections in the Islamic Republic of Iran. AB - This study aimed to evaluate the educational needs and knowledge about sexually transmittable infections (STIs) demonstrated by midwives. In a cross-sectional study in 2014, 144 midwives in Rasht, Islamic Republic of Iran, were surveyed. The Persian version of the Sexually Transmitted Disease Knowledge Questionnaire (STD-KQ) and a researcher-made questionnaire to evaluate educational needs and profile were used. The participants obtained 74% of the total score of STD-KQ. Thirty-one percent of participants were categorized in high or very high need of education. Seventy percent of midwives mentioned they were trained on all STIs at university. However, only 6.3% of midwives were aware of existing STIs guidelines. Participants reported that in the last two years they were only educated about HIV/AIDS and hepatitis B at their workplace. Thus, a comprehensive educational programme to empower midwives for complete STIs control is recommended. PMID- 29178119 TI - Development of an Eastern Mediterranean Region search strategy for biomedical citations indexed in PubMed. AB - PubMed, a 'barrier-free' bibliographic database covering biomedical and health disciplines, has been successfully used to identify a multitude of indicators that assist in analyzing global trends for biomedical research productivity. The current study represents an original attempt to develop and optimize an Eastern Mediterranean Region (EMR) search strategy in PubMed to pave the way for subsequent descriptive analyses. The refined EMR search strategy contains elaborate syntaxes which facilitate controlling the search process and maintaining a proper balance between sensitivity and precision of the obtained results. Country-specific citation data were manually scanned for false positive publications. Our results indicate that publication productivity increased nearly five-fold in the EMR from 2004 to 2013. Five countries (Islamic Republic of Iran, Egypt, Saudi Arabia, Tunisia and Pakistan; in order of total publications) contributed to 80% of all EMR publications during this period. Each of the remaining 17 EMR countries contributed less than 4%. We believe that the methodology presented in this study can be used in conjunction with other metrics to extract invaluable indicators to describe EMR health research systems. PMID- 29178120 TI - Awareness, attitudes and knowledge about evidencebased medicine among doctors in Gaza: a crosssectional survey. AB - Evidence-based medicine (EBM) has emerged as a strategy to integrate research evidence within clinical decision-making. We have explored awareness, knowledge and attitudes about EBM among doctors in the Gaza Strip. In 2014, we conducted a cross-sectional survey among doctors working in health centres in Gaza, using a 20 item, web-based self-administered questionnaire. Approximately two thirds of the respondents welcomed EBM in principle, and believed that it could improve patient care. However, they had a relatively low level of knowledge about EBM. The main barriers to EBM mentioned by respondents were lack of knowledge needed to practise EBM [n = 47 (35%)]; negative attitude among senior colleagues [n = 34 (25%)]; lack of relevant resources [n = 31 (23%)]; work overload [n = 27 (20%)]; and lack of institutional support [n = 248 (18%)]. Thus, there are personal and organisational barriers to its practice that need to be addressed. PMID- 29178121 TI - Study of congenital heart diseases in patients with Down syndrome in Algeria. AB - This study aimed to describe and evaluate the type, frequency and patterns of congenital heart diseases (CHDs) in patients with Down Syndrome (DS) in Setif, Algeria. Down Syndrome, or trisomy 21, is the most common genetic disorder in the world. Data were collected and followed from January 2009 to December 2013. Parental consanguinity documenting pedigree analyzing, chromosome analysis and clinical examination were carried out for all cases. Results have shown that 22 (15.4%; +/- 0.06) of the total 143 known cases of DS from DS centres have CHDs and 88 (10.6%; +/- 2.2) of the total 770 patients with CHDs collected from public departments at the child and maternity teaching hospital, Setif, have DS. Among the 110 cases, 75 (68%) have single cardiac abnormalities and 35 (32%) have multiple cardiac abnormalities. The most frequent CHDs were Atrioventricular Septal Defect (AVSD). In conclusion, our study will be helpful to demonstrate the current status of DS and to identify the distribution of CHD in patients with DS in Setif, Algeria, for further study. PMID- 29178122 TI - Evaluation of biomedical waste management in primary health care centres in Saudi Arabia: a knowledge, attitudes and practices study. AB - Awareness and knowledge of biomedical waste practices is very important for any health care setting. This study aimed to determine the knowledge, attitudes and practices (KAP) about biomedical waste among health professionals in primary health care centres in Hail City, Saudi Arabia. The study included 135 of 155 professionals who dealt with biomedical waste from 16 out of 26 primary health care centres. Data were collected using a structured questionnaire. Overall 54.8%, 48.9% and 49.6% of the participants had good knowledge, attitudes and practices scores respectively. Profession, education and age were significantly associated with KAP level (P < 0.01): doctors, those with a degree and older respondents had better KAP scores. There was a strong correlation between knowledge and attitudes, knowledge and practices, and attitudes and practices (P ? 0.05). Training is recommended to enhance the knowledge of the professionals dealing with biomedical waste in the primary health care centres.

AB - Innovation in continuous renal replacement therapies (CRRT) utilized to treat acute kidney injury (AKI) and sepsis, has brought new machines and techniques. Part of these new advances are due to the availability of innovative biomaterials and the construction of membranes with larger pores and wide distribution of pore sizes. This includes the creation of a new generation of high cut-off membranes whose utilization in clinical practice is promising for the wide spectrum of solutes that are removed during extracorporeal therapies.However, the enlargement of pore diameters brings some loss of albumin during treatment and this effect is still under evaluation, since there is a possibility that this is detrimental for the patient. A thorough review of the available clinical literature is reported in this paper with a reappraisal of the potential application of these new technologies. PMID- 29178125 TI - Laparoscopic versus open resection for sigmoid diverticulitis. AB - BACKGROUND: Diverticular disease is a common condition in Western industrialised countries. Most individuals remain asymptomatic throughout life; however, 25% experience acute diverticulitis. The standard treatment for acute diverticulitis is open surgery. Laparoscopic surgery - a minimal-access procedure - offers an alternative approach to open surgery, as it is characterised by reduced operative stress that may translate into shorter hospitalisation and more rapid recovery, as well as improved quality of life. OBJECTIVES: To evaluate the effectiveness of laparoscopic surgical resection compared with open surgical resection for individuals with acute sigmoid diverticulitis. SEARCH METHODS: We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 2) in the Cochrane Library; Ovid MEDLINE (1946 to 23 February 2017); Ovid Embase (1974 to 23 February 2017); clinicaltrials.gov (February 2017); and the World Health Organization (WHO) International Clinical Trials Registry (February 2017). We reviewed the bibliographies of identified trials to search for additional studies. SELECTION CRITERIA: We included randomised controlled trials comparing elective or emergency laparoscopic sigmoid resection versus open surgical resection for acute sigmoid diverticulitis. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies, assessed the domains of risk of bias from each included trial, and extracted data. For dichotomous outcomes, we calculated risk ratios (RRs) with 95% confidence intervals (CIs). For continuous outcomes, we planned to calculate mean differences (MDs) with 95% CIs for outcomes such as hospital stay, and standardised mean differences (SMDs) with 95% CIs for quality of life and global rating scales, if researchers used different scales. MAIN RESULTS: Three trials with 392 participants met the inclusion criteria. Studies were conducted in three European countries (Switzerland, Netherlands, and Germany). The median age of participants ranged from 62 to 66 years; 53% to 64% were female. Inclusion criteria differed among studies. One trial included participants with Hinchey I characteristics as well as those who underwent Hartmann's procedure; the second trial included only participants with "a proven stage II/III disease according to the classification of Stock and Hansen"; the third trial considered for inclusion patients with "diverticular disease of sigmoid colon documented by colonoscopy and 2 episodes of uncomplicated diverticulitis, one at least being documented with CT scan, 1 episode of complicated diverticulitis, with a pericolic abscess (Hinchey stage I) or pelvic abscess (Hinchey stage II) requiring percutaneous drainage."We determined that two studies were at low risk of selection bias; two that reported considerable dropouts were at high risk of attrition bias; none reported blinding of outcome assessors (unclear detection bias); and all were exposed to performance bias owing to the nature of the intervention.Available low quality evidence suggests that laparoscopic surgical resection may lead to little or no difference in mean hospital stay compared with open surgical resection (3 studies, 360 participants; MD -0.62 (days), 95% CI -2.49 to 1.25; I2 = 0%).Low quality evidence suggests that operating time was longer in the laparoscopic surgery group than in the open surgery group (3 studies, 360 participants; MD 49.28 (minutes), 95% CI 40.64 to 57.93; I2 = 0%).We are uncertain whether laparoscopic surgery improves postoperative pain between day 1 and day 3 more effectively than open surgery. Low-quality evidence suggests that laparoscopic surgery may improve postoperative pain at the fourth postoperative day more effectively than open surgery (2 studies, 250 participants; MD = -0.65, 95% CI 1.04 to -0.25).Researchers reported quality of life differently across trials, hindering the possibility of meta-analysis. Low-quality evidence from one trial using the Short Form (SF)-36 questionnaire six weeks after surgery suggests that laparoscopic intervention may improve quality of life, whereas evidence from two other trials using the European Organization for Research and Treatment of Cancer core quality of life questionnaire (EORTC QLQ-C30) v3 and the Gastrointestinal Quality of Life Index score, respectively, suggests that laparoscopic surgery may make little or no difference in improving quality of life compared with open surgery.We are uncertain whether laparoscopic surgery improves the following outcomes: 30-day postoperative mortality, early overall morbidity, major and minor complications, surgical complications, postoperative times to liquid and solid diets, and reoperations due to anastomotic leak. AUTHORS' CONCLUSIONS: Results from the present comprehensive review indicate that evidence to support or refute the safety and effectiveness of laparoscopic surgery versus open surgical resection for treatment of patients with acute diverticular disease is insufficient. Well-designed trials with adequate sample size are needed to investigate the efficacy of laparoscopic surgery towards important patient oriented (e.g. postoperative pain) and health system-oriented outcomes (e.g. mean hospital stay). PMID- 29178126 TI - A comparison between McGrath MAC videolaryngoscopy and Macintosh laryngoscopy in children. AB - BACKGROUND: This prospective, randomised, controlled study was performed to evaluate the usefulness of the McGrath VL compared with Macintosh laryngoscopy in children with expected normal airway during endotracheal intubation, by comparing the time to intubation and difficulty of intubation. METHODS: Eighty-four patients aged 1-10 years who underwent endotracheal intubation for elective surgery were randomly assigned to the McGrath group (n = 42) or the Macintosh group (n = 42). Anaesthesia was induced with 2.5-3.0 mg/kg of propofol and sevoflurane 5-8 vol%. Orotracheal intubation was performed 2 min after injection of rocuronium 0.6 mg/kg with McGrath VL or Macintosh laryngoscope; the primary outcome was the time to intubation. The Cormack and Lehane glottic grade, intubation difficulty score (IDS), and success rate on intubation were assessed. Haemodynamic changes were also recorded. RESULTS: As the primary outcome, median time to intubation [interquartile range] did not differ between the McGrath group and the Macintosh group (25.0 [22.8-28.3] s vs. 26.0 [24.0-29.0] s, P = 0.301). The incidence of grade I glottic view was significantly higher in the McGrath group than in the Macintosh group (95% vs. 74%, P = 0.013). Median IDS was lower in the McGrath group than in the Macintosh group (0 [0-0] vs. 0 [0-1], P = 0.018). There were no significant differences in success rate on intubation or haemodynamics between the two groups. CONCLUSIONS: McGrath VL provides better laryngeal views and lower IDS but similar intubation times and success rates compared with the Macintosh laryngoscope in children with normal airway.

AB - The influence of family, school, and religious social contexts on the mental health of Black adolescents has been understudied. This study used Durkheim's social integration theory to examine these associations in a nationally representative sample of 1,170 Black adolescents, ages 13-17. Mental health was represented by positive and negative psychosocial well-being indicators. Results showed that adolescents' integration into family and school were related to better mental health. In addition, commitment to religious involvement positively influenced mental health. Although the direct effect of religious involvement was inversely related to mental health, mediation analyses revealed a positive influence through religious commitment. Findings suggest a greater emphasis on all three social contexts when designing strategies to improve the mental health of Black adolescents.

AB - The Coral Triangle (CT) region of the Indo-Pacific realm harbors an extraordinary number of species, with richness decreasing away from this biodiversity hotspot. Despite multiple competing hypotheses, the dynamics underlying this regional diversity pattern remain poorly understood. Here, we use a time-calibrated evolutionary tree of living reef coral species, their current geographic ranges, and model-based estimates of regional rates of speciation, extinction, and geographic range shifts to show that origination rates within the CT are lower than in surrounding regions, a result inconsistent with the long-standing center of origin hypothesis. Furthermore, endemism of coral species in the CT is low, and the CT endemics are older than relatives found outside this region. Overall, our model results suggest that the high diversity of reef corals in the CT is largely due to range expansions into this region of species that evolved elsewhere. These findings strongly support the notion that geographic range shifts play a critical role in generating species diversity gradients. They also show that preserving the processes that gave rise to the striking diversity of corals in the CT requires protecting not just reefs within the hotspot, but also those in the surrounding areas. PMID- 29178129 TI - Depression and somatic symptoms in Japanese and American college students: Negative mood regulation expectancies as a personality correlate. AB - This study clarified contradictory findings regarding whether depression and somatic symptoms are associated more strongly with each other in non-Western countries than in Western countries, by examining the relationships of the two variables with negative mood regulation expectancies (NMRE). NMRE are beliefs about one's ability to improve one's negative moods. Participants were 155 Japanese and 176 American undergraduates. They completed self-report measures of NMRE, coping, depression and somatic symptoms. Results showed that depression significantly correlated with somatic symptoms for both men and women in both countries, and there was no cultural difference in the relationship between depression and somatic symptoms. The relationships of depression and somatic symptoms with NMRE did not differ between cultures. NMRE explained variance in depression in both countries but variance in somatic symptoms only for women in both countries. The relationship of NMRE with depression and somatic symptoms paralleled that between depression and somatic symptoms for both cultures. These results were consistent with the previous literature that found no difference between cultures. Results support the cross-cultural validity of measuring NMRE in the context of coping and distress.

AB - The care of patients with difficult-to-control asthma ("difficult asthma") is challenging and costly. Despite high-intensity asthma treatment, these patients experience poor asthma control and face the greatest risk of asthma morbidity and mortality. Poor asthma control is often driven by severe asthma biology, which has appropriately been the focus of intense research and phenotype-driven therapies. However, it is increasingly apparent that extra-pulmonary comorbidities also contribute substantially to poor asthma control and a heightened disease burden. These comorbidities have been proposed as "treatable traits" in chronic airways disease, adding impetus to their evaluation and management in difficult asthma. In this review, eight major asthma-related comorbidities are discussed: rhinitis, chronic rhinosinusitis, gastroesophageal reflux, obstructive sleep apnoea, vocal cord dysfunction, obesity, dysfunctional breathing and anxiety/depression. We describe the prevalence, impact and treatment effects of these comorbidities in the difficult asthma population, emphasizing gaps in the current literature. We examine the associations between individual comorbidities and highlight the potential for comorbidity clusters to exert combined effects on asthma outcomes. We conclude by outlining a pragmatic clinical approach to assess comorbidities in difficult asthma. PMID- 29178131 TI - The rapid-onset antidepressant effect of ketamine: More surprises? AB - WHAT IS KNOWN AND OBJECTIVE: An effective rapid-onset treatment for major depressive disorder could save lives. Extensive preclinical and clinical data demonstrate such an action of ketamine. However, the presumptive mechanism of action, inhibition of NMDA (N-methyl-D-aspartate) receptors, has recently been challenged. Elucidation of the mechanism is important clinically for drug discovery and for understanding the (patho)physiology of depression. COMMENT: The best-known pharmacologic property of ketamine is non-competitive inhibition of the NMDA subtype of glutamate receptor. Although other mechanisms have been postulated, this action has been assumed the major one that accounts for ketamine's antidepressant effect. However, a ketamine metabolite and a different mechanism have now been claimed to be necessary and sufficient for the effect. WHAT IS NEW AND CONCLUSION: A metabolite has been proposed to be responsible for the antidepressant action of ketamine, via activation of non-NMDA receptors. It will be important to determine which of the competing views is correct. PMID- 29178132 TI - Thrombopoietin receptor agonists for prevention and treatment of chemotherapy induced thrombocytopenia in patients with solid tumours. AB - BACKGROUND: Chemotherapy-induced thrombocytopenia (CIT) is defined as a peripheral platelet count less than 100*109/L, with or without bleeding in cancer patients receiving myelosuppressive chemotherapy. CIT is a significant medical problem during chemotherapy, and it carries the risk of sub-optimal overall survival and bleeding. Alternative interventions to platelet transfusion are limited. Different stages of preclinical and clinical studies have examined the thrombopoietin receptor agonists (TPO-RAs) for CIT in patients with solid tumours. OBJECTIVES: To assess the effects of TPO-RAs to prevent and treat CIT in patients with solid tumours:(1) to prevent CIT in patients without thrombocytopenia before chemotherapy, (2) to prevent recurrence of CIT, and (3) to treat CIT in patients with thrombocytopenia during chemotherapy. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL, to 28 September 2017), MEDLINE (from 1950 to 28 September 2017), as well as online registers of ongoing trials (Clinical Trials, Chinese Clinical Trial Register, Australian New Zealand Clinical Trial Registry, WHO ICTRP Search Portal, International Standard Randomised Controlled Trial Number registry, GlaxoSmithKline Clinical Study Register, and Amgen Clinical Trials) and conference proceedings (American Society of Hematology, American Society of Clinical Oncology, European Hematology Association, European Society of Medical Oncology, and Conference Proceedings Citation Index-Science, from 2002 up to September 2017) for studies. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing TPO-RAs alone, or in combination with other drugs, to placebo, no treatment, other drugs, or another TPO-RAs for CIT in patients with solid tumours. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the results of the search strategies, extracted data, assessed risk of bias, and analysed data according to standard methodological methods expected by Cochrane. MAIN RESULTS: We identified six trials eligible for inclusion, of which two are ongoing, and one awaiting classification study. The three included trials were conducted at many different sites in Europe, America, and Asia. All of the three studies recruited adult and elder participants (no children were included) with solid tumours, and compared TPO-RAs with placebo. No studies compared TPO-RAs alone, or in combination with other drugs, to no treatment, or other drugs, or another TPO-RAs.We judged the overall risk of bias as high as we found a high risk for detection bias. We assessed the risk of bias arising from inadequate blinding of outcome assessors as high for number and severity of bleeding episodes (one of the primary outcomes).To prevent CIT: We included two trials (206 participants) comparing TPO-RAs (eltrombopag, multiple-dose oral administration with chemotherapy) with placebo. The use of TPO-RAs may make little or no difference to the all-cause mortality at 33 weeks of follow-up (RR 1.35, 95% CI 0.53 to 3.45; one trial, 26 participants; low quality of evidence). There is not enough evidence to determine whether TPO-RAs reduce the number of patients with at least one bleeding episode of any severity (RR 0.62, 95% CI 0.22 to 1.78; two trials, 206 participants; very low quality of evidence). There is not enough evidence to determine whether TPO-RAs reduce the number of patients with at least one severe/life-threatening bleeding episode (RR 0.36, 95% CI 0.06 to 2.06; two trials, 206 participants; very low quality of evidence). No studies were found that looked at overall survival (one of the primary outcomes), the number of treatment cycles with at least one bleeding episode, the number of days on which bleeding occurred, the amount of bleeding, or quality of life.To prevent recurrence of CIT: We included one trial (62 participants) comparing TPO-RAs (romiplostim, single-dose subcutaneous administration with chemotherapy) with placebo. There is not enough evidence to determine whether TPO-RAs reduce the number of patients with at least one bleeding episode of any severity (RR 2.80, 95% CI 0.17 to 47.53; one trial, 62 participants; very low quality of evidence). There is not enough evidence to determine whether TPO-RAs reduce the number of patients with at least one severe/life-threatening bleeding episode (no severe/life-threatening bleeding episodes; one trial, 62 participants; very low quality of evidence). No studies were found that looked at overall survival (one of the primary outcomes), the number of treatment cycles with at least one bleeding episode, the number of days on which bleeding occurred, the amount of bleeding, or quality of life. We found one ongoing study (expected recruitment 74 participants), it is planned to give TPO-RAs (romiplostim, subcutaneous administration with chemotherapy) to participants, but to date this trial has not reported any outcomes.To treat CIT: We found one ongoing study (expected recruitment 83 participants), which is planned to give TPO-RAs (eltrombopag, seven days orally) to participants when their platelet counts are less than 75*109/L during chemotherapy. This trial was originally planned to complete in March 2017, however, the completion date has passed and no results are reported.The one awaiting classification study included patients without thrombocytopenia before chemotherapy (to prevent CIT), patients with thrombocytopenia during chemotherapy (to prevent recurrence of CIT), and other patients during chemotherapy (uncertain whether CIT had happened). There was no evidence for a difference in the number of patients with at least one bleeding episode of any severity (RR 0.27, 95% CI 0.07 to 1.02; one trial, 75 participants). There was no evidence for a difference in the number of patients with at least one severe/life-threatening bleeding episode (RR 0.44, 95% CI 0.03 to 6.77; one trial, 75 participants). This study did not address overall survival or quality of life. AUTHORS' CONCLUSIONS: No certain conclusions can be drawn due to the lack of strong evidence in the review. The available weak evidence did not support the use of TPO-RAs for preventing CIT or preventing recurrence of CIT in patients with solid tumours. There was no evidence to support the use of TPO-RAs for treating CIT in patients with solid tumours. PMID- 29178134 TI - Vector velocity imaging echocardiography to study the effects of submassive pulmonary embolism on the right atrium. AB - OBJECTIVES: To assess the effects of submassive pulmonary embolism (SMPE) on right atrial (RA) anatomy and function. BACKGROUND: Right ventricular dysfunction (RVD) is associated with adverse outcomes in SMPE. However, the effects of SMPE on the structure and function of the RA have received much less attention. METHODS: Fifty patients with SMPE documented by CT angiography (SMPE group) and evidence of RVD on two-dimensional echocardiography were retrospectively identified and compared to 50 controls (control group). Both RA and RV areas, volumes and fractional area change (FAC) were measured. Pulmonary artery systolic pressures were estimated. RA and RV longitudinal strains were obtained using vector velocity imaging (VVI). RESULTS: Compared with controls, RA and RV FACs were significantly reduced and associated with higher chamber volumes in the SMPE group. Global longitudinal RA strain was reduced in the SMPE group (29% + 11% vs 55% + 16%; P < .01), as was global RV longitudinal strain (-12% + 5% vs -20% + 5%, P < .01), when compared to the controls. A linear relationship existed between RV and RA strain in both groups; however, the curve was shifted downward among those with SMPE. Furthermore, ROC curve analysis suggests RA area performs better than RV area as a marker of SMPE. CONCLUSIONS: RA structure and function are adversely affected in SMPE, similar to the effects observed in RV. Lower RA strain appears to be a novel quantitative indicator of SMPE, and RA area may be a more sensitive marker of this condition and may provide additional prognostic information in this condition. PMID- 29178135 TI - Demographically idiosyncratic responses to climate change and rapid Pleistocene diversification of the walnut genus Juglans (Juglandaceae) revealed by whole genome sequences. AB - Whether species demography and diversification are driven primarily by extrinsic environmental changes such as climatic oscillations in the Quaternary or by intrinsic biological interactions like coevolution between antagonists is a matter of active debate. In fact, their relative importance can be assessed by tracking past population fluctuations over considerable time periods. We applied the pairwise sequentially Markovian coalescent approach on the genomes of 11 temperate Juglans species to estimate trajectories of changes in effective population size (Ne ) and used a Bayesian-coalescent based approach that simultaneously considers multiple genomes (G-PhoCS) to estimate divergence times between lineages. Ne curves of all study species converged 1.0 million yr ago, probably reflecting the time when the walnut genus last shared a common ancestor. This estimate was confirmed by the G-PhoCS estimates of divergence times. But all species did not react similarly to the dramatic climatic oscillations following early Pleistocene cooling, so the timing and amplitude of changes in Ne differed among species and even among conspecific lineages. The population histories of temperate walnut species were not driven by extrinsic environmental changes alone, and a key role was probably played by species-specific factors such as coevolutionary interactions with specialized pathogens. PMID- 29178133 TI - Variants with a low allele frequency detected in genomic DNA affect the accuracy of mutation detection in cell-free DNA by next-generation sequencing. AB - BACKGROUND: Next-generation sequencing of cell-free DNA (cfDNA) has been shown to be a useful noninvasive test for detecting mutations in solid tumors. METHODS: Targeted gene sequencing was performed with a panel of 263 cancer-related genes for cfDNA and genomic DNA of peripheral blood mononuclear cells (PBMCs) obtained from presurgical specimens of 6 lung cancer patients, and mutation calls in these samples were compared with those of primary tumors and corresponding patient derived xenografts (PDXs). RESULTS: Approximately 67% of the mutations detected in the tumor samples (primary tumors and/or PDXs) were also detected in genomic DNA from PBMCs as background mutations. These background mutations consisted of germline polymorphisms and a group of mutations with low allele frequencies, mostly <10%. These variants with a low allele frequency were repeatedly detected in all types of samples from the same patients and at similarly low allele frequency levels in PBMCs from different patients; this indicated that their detection might be derived from common causes, such as homologous sequences in the human genome. Allele frequencies of mutations detected in both primary tumors and cfDNA showed 2 patterns: 1) low allele frequencies (approximately 1%-10%) in cfDNA but high allele frequencies (usually >10% or >3-fold increase) in primary tumors and further enrichment in PDXs and 2) similar allele frequencies across samples. CONCLUSIONS: Because only a small fraction of total cfDNA might be derived from tumor cells, only mutations with the first allele frequency pattern may be regarded as tumor-specific mutations in cfDNA. Effective filtering of background mutations will be required to improve the accuracy of mutation calls in cfDNA. Cancer 2018;124:1061-9. (c) 2017 American Cancer Society.

PMID- 29178137 TI - Continuous Automated Model EvaluatiOn (CAMEO) complementing the critical assessment of structure prediction in CASP12. AB - Every second year, the community experiment "Critical Assessment of Techniques for Structure Prediction" (CASP) is conducting an independent blind assessment of structure prediction methods, providing a framework for comparing the performance of different approaches and discussing the latest developments in the field. Yet, developers of automated computational modeling methods clearly benefit from more frequent evaluations based on larger sets of data. The "Continuous Automated Model EvaluatiOn (CAMEO)" platform complements the CASP experiment by conducting fully automated blind prediction assessments based on the weekly pre-release of sequences of those structures, which are going to be published in the next release of the PDB Protein Data Bank. CAMEO publishes weekly benchmarking results based on models collected during a 4-day prediction window, on average assessing ca. 100 targets during a time frame of 5 weeks. CAMEO benchmarking data is generated consistently for all participating methods at the same point in time, enabling developers to benchmark and cross-validate their method's performance, and directly refer to the benchmarking results in publications. In order to facilitate server development and promote shorter release cycles, CAMEO sends weekly email with submission statistics and low performance warnings. Many participants of CASP have successfully employed CAMEO when preparing their methods for upcoming community experiments. CAMEO offers a variety of scores to allow benchmarking diverse aspects of structure prediction methods. By introducing new scoring schemes, CAMEO facilitates new development in areas of active research, for example, modeling quaternary structure, complexes, or ligand binding sites. PMID- 29178140 TI - First Direct Evidence of Cue Integration in Reorientation: A New Paradigm. AB - There are several models of the use of geometric and feature cues in reorientation (Cheng, Huttenlocher, & Newcombe, ). The adaptive combination approach posits that people integrate cues with weights that depend on cue salience and learning, or, when discrepancies are large, they choose between cues based on these variables (Cheng, Shettleworth, Huttenlocher, & Rieser, ; Newcombe & Huttenlocher, ). In a new paradigm designed to evaluate integration and choice, disoriented participants attempted to return to a heading direction, in a trapezoidal enclosure in which feature and geometric cues both unambiguously specified a heading, but later the feature was moved. With discrepancies greater than 90 degrees, participants choose geometry. With smaller discrepancies, integration appeared in three of five situations; otherwise, participants used geometry alone. Variation depended on direction of feature movement and whether the nearest corner was acute or obtuse. The results have implications for contrasting adaptive combination and modularity theory, and for future research, offering a new paradigm for reorientation research, and for testing cue integration more broadly. PMID- 29178139 TI - Phagocytic clearance of presynaptic dystrophies by reactive astrocytes in Alzheimer's disease. AB - Reactive astrogliosis, a complex process characterized by cell hypertrophy and upregulation of components of intermediate filaments, is a common feature in brains of Alzheimer's patients. Reactive astrocytes are found in close association with neuritic plaques; however, the precise role of these glial cells in disease pathogenesis is unknown. In this study, using immunohistochemical techniques and light and electron microscopy, we report that plaque-associated reactive astrocytes enwrap, engulf and may digest presynaptic dystrophies in the hippocampus of amyloid precursor protein/presenilin-1 (APP/PS1) mice. Microglia, the brain phagocytic population, was apparently not engaged in this clearance. Phagocytic reactive astrocytes were present in 35% and 67% of amyloid plaques at 6 and 12 months of age, respectively. The proportion of engulfed dystrophic neurites was low, around 7% of total dystrophies around plaques at both ages. This fact, along with the accumulation of dystrophic neurites during disease course, suggests that the efficiency of the astrocyte phagocytic process might be limited or impaired. Reactive astrocytes surrounding and engulfing dystrophic neurites were also detected in the hippocampus of Alzheimer's patients by confocal and ultrastructural analysis. We posit that the phagocytic activity of reactive astrocytes might contribute to clear dysfunctional synapses or synaptic debris, thereby restoring impaired neural circuits and reducing the inflammatory impact of damaged neuronal parts and/or limiting the amyloid pathology. Therefore, potentiation of the phagocytic properties of reactive astrocytes may represent a potential therapy in Alzheimer's disease.

AB - The interface between III-V and metal-oxide-semiconductor materials plays a central role in the operation of high-speed electronic devices, such as transistors and light-emitting diodes. The high-speed property gives the light emitting diodes a high response speed and low dark current, and they are widely used in communications, infrared remote sensing, optical detection, and other fields. The rational design of high-performance devices requires a detailed understanding of the electronic structure at this interface; however, this understanding remains a challenge, given the complex nature of surface interactions and the dynamic relationship between the morphology evolution and electronic structures. Herein, in situ transmission electron microscopy is used to probe and manipulate the structural and electrical properties of ZrO2 films on Al2 O3 and InGaAs substrate at the atomic scale. Interfacial defects resulting from the spillover of the oxygen-atom conduction-band wavefunctions are resolved. This study unearths the fundamental defect-driven interfacial electric structure of III-V semiconductor materials and paves the way to future high-speed and high reliability devices. PMID- 29178142 TI - Three-dimensional echocardiography to evaluate right atrial volume and phasic function in pulmonary hypertension. AB - OBJECTIVE: Pulmonary hypertension (PH) impairs right ventricular (RV) systolic and diastolic function, which in turn induces compensatory changes in right atrial (RA) function; the diverse effects on RA function are subject to much debate. We hypothesized that RA function plays a more important role in compensating RV dysfunction, than mere prevention of clinical failure in patients with PH. METHODS: We studied 54 patients with PH and 23 healthy controls. RA volume, including maximum RA volume, minimum RA volume, and the volume before atrial systole, was evaluated by 3DE. RA maximum volume index (Vmax I), total emptying volume index (TotEVI), passive emptying volume index (PassEVI), and active ejection fraction (ActEF) were calculated. Receiver operating characteristic curve analysis was used to determine the sensitivity and specificity of various cutoff levels of the variables measured for predicting World Health Organization functional class (WHO-FC) IV in patients with PH. RESULTS: RAVmax I in patients with PH was higher than that in controls. In patients with PH, the TotEVI was significantly higher, while PassEVI was significantly lower as compared to that in controls. ActEF was increased in patients with WHO functional class (WHO-FC) III PH as compared to that in controls (P = .003) but was reduced in more advanced cases (WHO-FC IV). In addition, the area under the curve of 3D RA ActEF was larger than those of 2D RA ActEF, RA GLS, RA area, FAC, TAPSE, and RIMP (P < .01 for all) for predicting WHO FC IV. CONCLUSION: We demonstrated that RA function plays a more important role in compensating RV dysfunction then mere prevention of clinical failure in PH. PMID- 29178143 TI - Peptide modulators of Rac1/Tiam1 protein-protein interaction: An alternative approach for cardiovascular diseases. AB - Rac1 GTPase interaction with guanine nucleotide exchange factor Tiam1 is involved in several cancer types and cardiovascular diseases. Although small molecules interfering with their protein-protein interaction (PPI) were identified and studied, the ability of small peptides and peptide mimics acting as Rac1/Tiam1 PPI inhibitors has not been yet explored. Using computational alanine scanning (CAS), the "hot" interfacial residues have been determined allowing the design of a small library of putative PPI inhibitors. In particular, the insertion of an unnatural alpha, alpha disubstituted amino acid, that is norbornane amino acid, and the side chain stapling have been evaluated regarding both conformational stability and biological activity. REMD calculations and CD studies have indicated that one single norbornane amino acid at the N-terminus is not sufficient to stabilize the helix structure, while the side-chain stapling is a more efficient strategy. Furthermore, both engineered peptides have been found able to reduce Rac1-GTP levels in cultured human smooth muscle cells, while wild type sequence is not active.

PMID- 29178145 TI - Comparative epigenomics reveals evolution of duplicated genes in potato and tomato. AB - The evolution of duplicated genes after polyploidization has been the subject of many evolutionary biology studies. Potato (Solanum tuberosum) and tomato (Solanum lycopersicum) are the first two sequenced genomes of asterids, and share a common polyploidization event. However, the epigenetic role of DNA methylation on the evolution of duplicated genes derived from polyploidization is not fully understood. Here, we explore the role of the DNA methylation in the evolution of duplicated genes in potato and tomato. The overall levels of DNA methylation are different, although patterns of DNA methylation are similar in potato and tomato. Different types of duplicated genes can display different methylation patterns in potato and tomato. In addition, we found that differences in the methylation levels between duplicated genes were associated with gene expression divergence. In particular, for the majority of duplicated gene pairs, one copy is always hyper- or hypo-methylated compared with the other copy across different tomato fruit ripening stages, and these genes are enriched for specific function related to transcription factor (TF) activity. Furthermore, transcription of hundreds of duplicated TFs was shown to be regulated by DNA methylation during fruit ripening stages in tomato, some of which are well-known fruit ripening TFs. Taken together, our results support the notion that DNA methylation may facilitate divergent evolution of duplicated genes and play roles in important biological processes such as tomato fruit ripening. PMID- 29178146 TI - BRAF mutations might be more common than supposed in vulvar melanomas. AB - Data on BRAF, NRAS and KIT mutations are scarce in patients with vulvo-vaginal melanomas and are associated with important therapeutic issues. We investigated their prevalence in a cohort of patients with female lower genital tract melanomas between 2003 and 2017. Of the 22 patients, 5 (22.7%) harboured a BRAF mutation, which was much higher than the rate of 5% reported in the literature. One patient, who was tested negative on the primary melanoma, had a NRAS mutation in a cutaneous metastasis. Our data provide a rationale for prospective and repeated mutations testing in female lower genital tract melanomas. PMID- 29178147 TI - Psychosocial predictors of distress and depression among South African breast cancer patients. AB - OBJECTIVE: The present study focused on psychological distress and symptoms of depression among a sample of patients attending an outpatient breast cancer clinic in South Africa. The authors also sought to identify the predictors of distress and depression by using demographic, medical, and psychosocial variables, including perceived and received social support. METHODS: A convenience sample of breast cancer patients was recruited from the Breast Clinic at a hospital in the Western Cape, South Africa. Participants (N = 201) were asked to complete a questionnaire battery consisting of, inter alia, the Center for Epidemiological Studies-Depression Scale, the Hopkins Symptom Checklist, and the Berlin Social Support Scales. RESULTS: More than one-third of participants scored in the elevated ranges on the Center for Epidemiological Studies Depression Scale and Hopkins Symptom Checklist, indicating that distress and symptoms of depression were a concern for a sizable minority of participants. Regression analysis showed that body change stress and perceived social support were significant predictors of both psychological distress and symptoms of depression. CONCLUSIONS: Distress and depressive symptoms are prevalent among South African breast cancer patients, especially those with higher body change stress and lower perceived support. For breast cancer patients who are distressed or have symptoms of depression, social support, information, psychosocial counseling, and in some cases, referral for medication management and cognitive psychotherapy is indicated. This article calls attention to the need for psychosocial services directed at supporting patients receiving care at breast clinics in South Africa. PMID- 29178148 TI - Confined Synthesis of Carbon Nitride in a Layered Host Matrix with Unprecedented Solid-State Quantum Yield and Stability. AB - Fluorescent carbon nanomaterials have drawn tremendous attention for their intriguing optical performances, but their employment in solid-state luminescent devices is rather limited as a result of aggregation-induced photoluminescence quenching. Herein, ultrathin carbon nitride (CN) is synthesized within the 2D confined region of layered double hydroxide (LDH) via triggering the interlayer condensation reaction of citric acid and urea. The resulting CN/LDH phosphor emits strong cyan light under UV-light irradiation with an absolute solid-state quantum yield (SSQY) of 95.9 +/- 2.2%, which is, to the best of our knowledge, the highest value of carbon-based fluorescent materials ever reported. Furthermore, it exhibits a strong luminescence stability toward temperature, environmental pH, and photocorrosion. Both experimental studies and theoretical calculations reveal that the host-guest interactions between the rigid LDH matrix and interlayer carbon nitride give the predominant contribution to the unprecedented SSQY and stability. In addition, prospective applications of the CN/LDH material are demonstrated in both white light-emitting diodes and upconversion fluorescence imaging of cancer cells. PMID- 29178149 TI - Measuring activities and participation in persons with haemophilia: A systematic review of commonly used instruments. AB - INTRODUCTION: Monitoring clinical outcome in persons with haemophilia (PWH) is essential in order to provide optimal treatment for individual patients and compare effectiveness of treatment strategies. Experience with measurement of activities and participation in haemophilia is limited and consensus on preferred tools is lacking. AIM: The aim of this study was to give a comprehensive overview of the measurement properties of a selection of commonly used tools developed to assess activities and participation in PWH. METHODS: Electronic databases were searched for articles that reported on reliability, validity or responsiveness of predetermined measurement tools (5 self-reported and 4 performance based measurement tools). Methodological quality of the studies was assessed according to the COSMIN checklist. Best evidence synthesis was used to summarize evidence on the measurement properties. RESULTS: The search resulted in 3453 unique hits. Forty-two articles were included. The self-reported Haemophilia Acitivity List (HAL), Pediatric HAL (PedHAL) and the performance based Functional Independence Score in Haemophilia (FISH) were studied most extensively. Methodological quality of the studies was limited. Measurement error, cross-cultural validity and responsiveness have been insufficiently evaluated. CONCLUSION: Albeit based on limited evidence, the measurement properties of the PedHAL, HAL and FISH are currently considered most satisfactory. Further research needs to focus on measurement error, responsiveness, interpretability and cross-cultural validity of the self-reported tools and validity of performance based tools which are able to assess limitations in sports and leisure activities. PMID- 29178150 TI - Towards a Kieselguhr- and PVPP-Free Clarification and Stabilization Process of Rough Beer at Room-Temperature Conditions. AB - : In this work, the main constraint (that is, beer chilling and chill haze removing) of the current beer conditioning techniques using Kieselguhr filtration and Polyvinylpolypyrrolidone (PVPP) treatment was overcome by developing a novel higher-throughput conditioning process, operating at room temperatures with no use of filter aids. The effect of filtration temperature (TF ) in the range of 0 to 40 degrees C on the hydraulic permeability of ceramic hollow-fiber (HF) membranes with nominal pore size of 0.2 to 1.4 MUm, as well as on their limiting permeation flux (J* ) when feeding precentrifuged rough beer, was preliminarily assessed. When using the 1.4-MUm HF membrane operating at TF >= 20 degrees C, it was possible to enhance the average permeation flux at values (676 to 1844 L/m2 /h), noticeably higher than those (250 to 500 L/m2 /h) characteristics of conventional powder filtration. Despite its acceptable permanent haze, the resulting beer permeate still exhibited colloidal instability. By resorting to the commercial enzyme preparation Brewers Clarex(r) before beer clarification, it was possible to significantly improve its colloidal stability as measured using a number of European Brewing Convention forcing tests, especially with respect to that of precentrifuged rough beer by itself. By combining the above enzymatic treatment with membrane clarification at 30 degrees C across the ceramic 1.4-MUm HF membrane module, it was possible to limit the haze development due to chilling, sensitive proteins, and alcohol addition to as low as 0.78, 4.1, and 4.0 EBC-U, respectively, the enzymatic treatment being by far more effective than that using PVPP. PRACTICAL APPLICATION: A novel Kieselguhr- and PVPP-free rough beer conditioning process at room temperatures was set up. By submitting precentrifuged rough beer to commercial preparation Brewers Clarex (r) and then to membrane clarification at 30 degrees C across a ceramic 1.4-MUm hollow-fiber membrane module, it was possible to obtain a clear and stable beer with a throughput (1306 +/- 72 L/m2 /h) by far higher than that (250 to 500 L/m2 /h) characterizing the current powder filters. The haze development due to chilling, sensitive proteins, and alcohol adding was by far lower than that observed when microfiltering PVPP-pretreated rough beer.

AB - Solid-state batteries (SSBs) are promising for safer energy storage, but their active loading and energy density have been limited by large interfacial impedance caused by the poor Li+ transport kinetics between the solid-state electrolyte and the electrode materials. To address the interfacial issue and achieve higher energy density, herein, a novel solid-like electrolyte (SLE) based on ionic-liquid-impregnated metal-organic framework nanocrystals (Li-IL@MOF) is reported, which demonstrates excellent electrochemical properties, including a high room-temperature ionic conductivity of 3.0 * 10-4 S cm-1 , an improved Li+ transference number of 0.36, and good compatibilities against both Li metal and active electrodes with low interfacial resistances. The Li-IL@MOF SLE is further integrated into a rechargeable Li|LiFePO4 SSB with an unprecedented active loading of 25 mg cm-2 , and the battery exhibits remarkable performance over a wide temperature range from -20 up to 150 degrees C. Besides the intrinsically high ionic conductivity of Li-IL@MOF, the unique interfacial contact between the SLE and the active electrodes owing to an interfacial wettability effect of the nanoconfined Li-IL guests, which creates an effective 3D Li+ conductive network throughout the whole battery, is considered to be the key factor for the excellent performance of the SSB.

AB - RATIONALE: Catharanthus roseus is a well-known dicotyledonous medicinal plant containing diverse classes of bioactive terpene indole alkaloids (TIAs), in particular the anticancer agents vinblastine and vincristine. In view of the commercial importance of these compounds there is an urgent need to develop an accurate and reliable method for the screening of TIAs from C. roseus. METHODS: A method for the separation and characterization of these compounds was developed using high-performance liquid chromatography coupled with positive electrospray ionization quadrupole time-of-flight tandem mass spectrometry (HPLC/ESI-QTOF MS/MS). Chromatographic separation of TIAs was carried out using a Thermo Betasil C8 column (250 mm * 4.5 mm, 5 MUm) at 25 degrees C using 0.1% formic acid in water and acetonitrile. RESULTS: Diagnostic fragmentation pathways for vinpocetine, vindesine, catharanthine, vinblastine, vindoline and vincristine were established on the basis of their product ions. A total of 72 TIAs were detected of which 11 were unambiguously identified by comparison with their standards, and the remaining 61 were tentatively identified. The geographical distribution of the TIAs in ethanolic extracts of 30 samples of C. roseus collected from five states of India was studied using principal component analysis (PCA). CONCLUSIONS: The developed analytical method together with diagnostic fragment patterns were used to rapidly and effectively identify targeted and untargeted TIAs in C. roseus. A PCA study of the results obtained was used to discriminate among the C. roseus samples.

AB - In our study, we have characterized the prefibrillar aggregates of human serum albumin (HSA) induced by temsirolimus, anti-renal cancer drug. Molecular docking was retorted to confirm binding of HSA and temsirolimus. Temsirolimus caused the structural transition of native HSA to non-native species after prolonged incubation of 20 days. These non-native species were characterized as prefibrillar aggregates as evident by decreased intrinsic fluorescence and enhanced 8-anilino-1-naphthalene-sulphonic acid (ANS) fluorescence. Further, enhanced thioflavin T fluorescence and shift in congo red (CR) spectra of temsirolimus-incubated HSA as compared to native HSA are suggestive of global transition of HSA in presence of temsirolimus towards prefibrillar aggregates. Circular dichroism spectroscopy revealed alpha to beta transition upon prolonged incubation with temsirolimus suggesting the formation of prefibrillar aggregates as aggregates are known to possess high beta content. Scanning electron microscopy confirmed these non-native species to be prefibrillar aggregates evident by observed sheath-like structures. Comet assay was retorted to confirm genotoxic nature of these prefibrillar aggregates; DNA damage was observed for temsirolimus-incubated HSA confirming the genotoxic nature of prefibrillar aggregates. These prefibrillar aggregates are observed at heart of many pathological conditions, thus making our study clinically significant.

AB - Lithium and sodium metal batteries are considered as promising next-generation energy storage devices due to their ultrahigh energy densities. The high reactivity of alkali metal toward organic solvents and salts results in side reactions, which further lead to undesirable electrolyte depletion, cell failure, and evolution of flammable gas. Herein, first-principles calculations and in situ optical microscopy are used to study the mechanism of organic electrolyte decomposition and gas evolution on a sodium metal anode. Once complexed with sodium ions, solvent molecules show a reduced LUMO, which facilitates the electrolyte decomposition and gas evolution. Such a general mechanism is also applicable to lithium and other metal anodes. We uncover the critical role of ion solvent complexation for the stability of alkali metal anodes, reveal the mechanism of electrolyte gassing, and provide a mechanistic guidance to electrolyte and lithium/sodium anode design for safe rechargeable batteries.

PMID- 29178158 TI - Pre-exposure prophylaxis: awareness, acceptability and risk compensation behaviour among men who have sex with men and the transgender population. AB - OBJECTIVES: This exploratory study examined the facilitators of and barriers to acceptance of pre-exposure prophylaxis (PrEP) and potential risk compensation behaviour emerging from its use among men who have sex with men (MSM) and transgender individuals (TGs) in India. METHODS: A questionnaire was administered to 400 individuals registered with a targeted intervention programme. Logistic regression models were used to identify facilitators of and barriers to PrEP acceptance. RESULTS: The respondents consisted of 68% MSM and 32% TGs. Risk behaviour categorization identified 40% as low risk, 41% as medium risk and, 19% as high risk for HIV infection. About 93% of the respondents were unaware of PrEP, but once informed about it, 99% were willing to use PrEP. The facilitators of PrEP acceptance were some schooling [odds ratio (OR) 2.16; P = 0.51], being married or in a live-in relationship (OR 2.08; P = 0.46), having a high calculated risk (OR 3.12; P = 0.33), and having a high self-perceived risk (OR 1.8; P = 0.35). Increasing age (OR 2.12; P = 0.04) was a significant barrier. TGs had higher odds of acceptance of PrEP under conditions of additional cost (OR 2.12; P = 0.02) and once-daily pill (OR 2.85; P = 0.04). Individuals identified as low risk for HIV infection showed lower odds of potential risk compensation, defined as more sexual partners (OR 0.8; P = 0.35), unsafe sex with new partners (OR 0.71; P = 0.16), and decreased condom use with regular partners (OR 0.95; P = 0.84), as compared with medium-risk individuals. The associations, although not statistically significant, are nevertheless important for public health action given the limited scientific evidence on PrEP use among MSM and TGs in India. CONCLUSIONS: With high acceptability and a low likelihood of risk compensation behaviour, PrEP can be considered as an effective prevention strategy for HIV infection among MSM and TGs in India. PMID- 29178159 TI - Crystallographic insights into the self-assembly of KLVFF amyloid-beta peptides. AB - Amyloidogenic peptide fragment KLVFF (H2 N-Lys-Leu-Val-Phe-Phe-COOH, Abeta16-20 ), the core-sequence of the polypeptide Abeta40, is a well-studied model for amyloid formation. However, due to its low crystallinity, detailed atomic information of KLVFF structure is lacking. Here we report the high-resolution single-crystal X-ray structure of two monohalogenated KLVFF derivatives, KLVFF(I) and KLVFF(Br). The obtained results highlight how halogenation is a good strategy to promote crystallization and facilitate the phase determination of KLVFF(I) and KLVFF(Br) fragments. Detailed structural studies on the packing features of both monohalogenated derivatives reveal the role of the halogen atoms showing that when they are positioned on the Phe aromatic moiety at the C-terminus they do not form halogen bonds and thus do not produce any extra stabilization of the beta sheet in the self-assembly process. The structural evidences gained from these studies corroborate the various polymorphic nanostructures of the halogenated variants of KLVFF and confirm the possibility to use halogenation as innovative strategy to tune the morphology of this pentapeptide.

AB - PURPOSE: Due to the considerable development of proton radiotherapy, several proton platforms have emerged to irradiate small animals in order to study the biological effectiveness of proton radiation. A dedicated analytical treatment planning tool was developed in this study to accurately calculate the delivered dose given the specific constraints imposed by the small dimensions of the irradiated areas. METHODS: The treatment planning system (TPS) developed in this study is based on an analytical formulation of the Bragg peak and uses experimental range values of protons. The method was validated after comparison with experimental data from the literature and then compared to Monte Carlo simulations conducted using Geant4. Three examples of treatment planning, performed with phantoms made of water targets and bone-slab insert, were generated with the analytical formulation and Geant4. Each treatment planning was evaluated using dose-volume histograms and gamma index maps. RESULTS: We demonstrate the value of the analytical function for mouse irradiation, which requires a targeting accuracy of 0.1 mm. Using the appropriate database, the analytical modeling limits the errors caused by misestimating the stopping power. For example, 99% of a 1-mm tumor irradiated with a 24-MeV beam receives the prescribed dose. The analytical dose deviations from the prescribed dose remain within the dose tolerances stated by report 62 of the International Commission on Radiation Units and Measurements for all tested configurations. In addition, the gamma index maps show that the highly constrained targeting accuracy of 0.1 mm for mouse irradiation leads to a significant disagreement between Geant4 and the reference. This simulated treatment planning is nevertheless compatible with a targeting accuracy exceeding 0.2 mm, corresponding to rat and rabbit irradiations. CONCLUSION: Good dose accuracy for millimetric tumors is achieved with the analytical calculation used in this work. These volume sizes are typical in mouse models for radiation studies. Our results demonstrate that the choice of analytical rather than simulated treatment planning depends on the animal model under consideration.

PMID- 29178165 TI - Outcomes of cellophane banding or percutaneous transvenous coil embolization of canine intrahepatic portosystemic shunts. AB - OBJECTIVE: To compare clinical outcomes of dogs with congenital intrahepatic portosystemic shunts (CIHPSS) treated with cellophane banding (CB) or percutaneous transvenous coil embolization (PTCE). STUDY DESIGN: Dual institutional retrospective study. ANIMALS: Fifty-eight dogs with CIHPSS (2001 2016). METHODS: Medical records of dogs undergoing CB or PTCE for CIHPSS were reviewed for signalment, body weight, hematologic values, shunt location, attenuation technique, procedure time, duration of hospitalization, complications, date of follow-up, and cause of death if applicable. RESULTS: Thirty-one dogs underwent CB, and 27 dogs underwent PTCE. No differences were detected between groups for gender, preoperative packed cell volume, albumin, cholesterol, or bile acids. Body weight was greater in dogs treated via PTCE. Shunts differed in location because dogs undergoing CB were diagnosed with more left divisional shunts compared with PTCE dogs. Procedural duration of CB and PTCE did not differ. Dogs treated with CB sustained more minor postoperative complications and were hospitalized longer than dogs treated with PTCE. The 1 year and 2-year survival rates were 89% for the CB group and 87% and 80% for the PTCE group, respectively. The proportion surviving at 5 years was 75% and 80% for CB dogs and PTCE dogs, respectively. CONCLUSION: CB and PTCE are associated with similar short-term and intermediate-term survival. PTCE is a minimally invasive alternative to CB via celiotomy. However, CB allows concurrent abdominal procedures requiring the same approach. PMID- 29178166 TI - Efficacy of irrigant activation techniques in removing intracanal smear layer and debris from mature permanent teeth: a systematic review and meta-analysis. AB - AIMS: To establish whether irrigant activation techniques (IATs) result in greater intracanal smear layer and debris removal than conventional needle irrigation (CNI). METHODOLOGY: Six electronic databases were searched to identify scanning electron microscopy studies evaluating smear layer and/or debris removal following the use of manual dynamic activation (MDA), passive ultrasonic irrigation (PUI), sonic irrigation (SI) or apical negative pressure (ANP) IATs in mature permanent teeth. Meta-analyses were performed for each canal segment (coronal, middle, apical and apical 1 mm) in addition to subgroup analyses for individual IATs with respect to CNI. Outcomes were presented as standardized mean differences (SMD) alongside 95% confidence intervals (95% CI) and chi-squared analysis. RESULTS: From 252 citations, 16 studies were identified. The meta analyses demonstrated significant improvements in coronal (SMD: 1.15, 95% CI: 0.72-1.57 / SMD: 0.54, 95% CI: 0.29-0.80), middle (SMD: 1.30, 95% CI: 0.59-2.53 / SMD: 0.8, 95% CI: 0.58-1.13) and apical thirds (SMD: 1.22, 95% CI: 0.83-1.62 / SMD: 1.86, 95% CI: 0.76-2.96) for smear layer and debris removal, respectively. In the apical 1 mm IATs improved cleanliness; however, differences were insignificant (SMD: 1.15, 95% CI: -0.47-2.77). Chi-squared analysis revealed heterogeneity scores of 79.3-92.8% and 0.0-93.5% for smear layer and debris removal, respectively. CONCLUSIONS: IATs improve intracanal cleanliness across a substantial portion of the canal, and therefore, their use is recommended throughout root canal preparation. However, current data is too heterogeneous to compare and identify superiority of an individual technique highlighting the need to standardize experimental protocols and develop a more representative research model to investigate the in vivo impact of IATs on clinical outcomes and periapical healing following root canal treatment.

AB - A high light-absorption coefficient and long-range hot-carrier transport of hybrid organic-inorganic perovskites give huge potential to their composites in solar energy conversion and environmental protection. Understanding interfacial interactions and their effects are paramount for designing perovskite-based heterostructures with desirable properties. Herein, we systematically investigated the interfacial interactions in monolayer and few-layer SnS/CH3 NH3 PbI3 heterostructures and their effects on the electronic and optical properties of these structures by density functional theory. It was found that the interfacial interactions in SnS/CH3 NH3 PbI3 heterostructures were van der Waals (vdW) interactions, and they were found to be insensitive to the layer number of 2D SnS sheets. Interestingly, although their band gap decreased upon increasing the layer number of SnS, the near-gap electronic states and optical absorption spectra of these heterostructures were found to be strikingly similar. This feature was determined to be critical for the design of 2D layered SnS-based heterostructures. Strong absorption in the ultraviolet and visible-light regions, type II staggered band alignment at the interface, and few-layer SnS as an active co-catalyst make 2D SnS/CH3 NH3 PbI3 heterostructures promising candidates for photocatalysis, photodetectors, and solar energy harvesting and conversion. These results provide first insight into the nature of interfacial interactions and are useful for designing hybrid organic-inorganic perovskite-based devices with novel properties. PMID- 29178168 TI - Core information set for informed consent to surgery for oral or oropharyngeal cancer: A mixed-methods study. AB - OBJECTIVES: To develop a core information set for informed consent to surgery for oral/oropharyngeal surgery. A core information set is baseline information rated important by patients and surgeons and is intended to improve patients' understanding of the intended procedure. DESIGN: A mixed-methods study. Systematic reviews of scientific and written healthcare literature, qualitative interviews and observations, Delphi surveys, and group consensus meetings identified information domains of importance for consent. SETTING: A regional head and neck clinic in the United Kingdom. Questionnaire participants were recruited from around the UK. PARTICIPANTS: Patients about to undergo, or who had previously undergone, surgery for oral/oropharyngeal cancer. Healthcare professionals involved in the management of head and neck cancer. MAIN OUTCOME MEASURES: The main outcome was a core information set. RESULTS: Systematic reviews, interviews and consultation observations yielded 887 pieces of information that were categorised into 87 information domains. Survey response rates were 67% (n = 50) and 71% (n = 52) for patient and healthcare professional groups in round one. More than 90% responded in each group in the second round. Healthcare professionals were more likely to rate information about short-term or peri-operative events as important while patients rated longer term issues about survival and quality of life. The consensus-building process resulted in an agreed core information set of 13 domains plus two procedure-specific domains about tracheostomy and free-flap surgery. CONCLUSION: This study produced a core information set for surgeons and patients to discuss before surgery for oral/oropharyngeal cancer. Future work will optimise ways to integrate core information into routine consultations. PMID- 29178169 TI - Authentication of commercial spices based on the similarities between gas chromatographic fingerprints. AB - BACKGROUND: A simple and solvent-free method was developed for the authentication of commercial spices. The similarities between gas chromatographic fingerprints were measured using similarity indices and multivariate data analyses, as morphological differentiation between dried powders and small spice particles was challenging. The volatile compounds present in 11 spices (i.e. allspice, anise, black pepper, caraway, clove, coriander, cumin, dill, fennel, star anise, and white pepper) were extracted by headspace solid-phase microextraction, and analysed by gas chromatography-mass spectrometry. RESULTS: The largest 10 peaks were selected from each total ion chromatogram, and a total of 65 volatiles were tentatively identified. The similarity indices (i.e. the congruence coefficients) were calculated using the data matrices of the identified compound relative peak areas to differentiate between two sets of fingerprints. Where pairs of similar fingerprints produced high congruence coefficients (>0.80), distinctive volatile markers were employed to distinguish between these samples. In addition, hierarchical cluster analysis and principal component analysis were performed to visualise the similarity among fingerprints, and the analysed spices were grouped and characterised according to their distinctive major components. CONCLUSION: This method is suitable for screening unknown spices, and can therefore be employed to evaluate the quality and authenticity of various spices. (c) 2017 Society of Chemical Industry.

AB - AIMS: To quantify the impact of life course income trajectories on periodontitis in adulthood. MATERIALS AND METHODS: Data from the 1982 Pelotas Birth Cohort Study, Brazil, were used. Information on family income was collected at birth and ages 15, 19, 23 and 30 years. Group-based trajectory modelling was used to identify income trajectories. Periodontal measures were assessed through clinical examination at age 31. Log-Poisson regression models were used to estimate prevalence ratios (PRs) of any and moderate/severe periodontitis, as outcomes. RESULTS: Prevalence of any periodontitis and moderate/severe periodontitis was 37.3% and 14.3% (n = 539). Income trajectories were associated with prevalence of moderate/severe periodontitis. Adjusted PR in participants in low and variable income trajectory was 2.1 times higher than in participants in stable high-income trajectory. The unadjusted association between income trajectories and prevalence of any periodontitis was explained by the inclusion of behavioural and clinical variables in the model. CONCLUSIONS: Low and variable life course income increased the prevalence of moderate/severe periodontitis at age 31 years. The findings may inform programmes in identifying and targeting potentially at-risk groups during the life course to prevent periodontitis. PMID- 29178172 TI - Anti-adhesion therapy following operative hysteroscopy for treatment of female subfertility. AB - BACKGROUND: Observational evidence suggests a potential benefit with several anti adhesion therapies in women undergoing operative hysteroscopy (e.g. insertion of an intrauterine device or balloon, hormonal treatment, barrier gels or human amniotic membrane grafting) for decreasing intrauterine adhesions (IUAs). OBJECTIVES: To assess the effectiveness of anti-adhesion therapies versus placebo, no treatment or any other anti-adhesion therapy, following operative hysteroscopy for treatment of female subfertility. SEARCH METHODS: We searched the following databases from inception to June 2017: the Cochrane Gynaecology and Fertility Group Specialised Register; the Cochrane Central Register of Studies (CRSO); MEDLINE; Embase; CINAHL and other electronic sources of trials, including trial registers, sources of unpublished literature and reference lists. We handsearched the Journal of Minimally Invasive Gynecology, and we contacted experts in the field. We also searched reference lists of appropriate papers. SELECTION CRITERIA: Randomised controlled trials (RCTs) of anti-adhesion therapies versus placebo, no treatment or any other anti-adhesion therapy following operative hysteroscopy in subfertile women. The primary outcome was live birth. Secondary outcomes were clinical pregnancy, miscarriage and IUAs present at second-look hysteroscopy, along with mean adhesion scores and severity of IUAs. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies, assessed risk of bias, extracted data and evaluated quality of evidence using the GRADE method. MAIN RESULTS: The overall quality of the evidence was low to very low. The main limitations were serious risk of bias related to blinding of participants and personnel, indirectness and imprecision. We identified 16 RCTs comparing a device versus no treatment (two studies; 90 women), hormonal treatment versus no treatment or placebo (two studies; 136 women), device combined with hormonal treatment versus no treatment (one study; 20 women), barrier gel versus no treatment (five studies; 464 women), device with graft versus device without graft (three studies; 190 women), one type of device versus another device (one study; 201 women), gel combined with hormonal treatment and antibiotics versus hormonal treatment with antibiotics (one study; 52 women) and device combined with gel versus device (one study; 120 women). The total number of participants was 1273, but data on 1133 women were available for analysis. Only two of 16 studies included 100% infertile women; in all other studies, the proportion was variable or unknown.No study reported live birth, but some (five studies) reported outcomes that were used as surrogate outcomes for live birth (term delivery or ongoing pregnancy). Anti-adhesion therapy versus placebo or no treatment following operative hysteroscopy.There was insufficient evidence to determine whether there was a difference between the use of a device or hormonal treatment compared to no treatment or placebo with respect to term delivery or ongoing pregnancy rates (odds ratio (OR) 0.94, 95% confidence interval (CI) 0.42 to 2.12; 107 women; 2 studies; I2 = 0%; very-low-quality evidence).There were fewer IUAs at second-look hysteroscopy using a device with or without hormonal treatment or hormonal treatment or barrier gels compared with no treatment or placebo (OR 0.35, 95% CI 0.21 to 0.60; 560 women; 8 studies; I2 = 0%; low-quality evidence). The number needed to treat for an additional beneficial outcome (NNTB) was 9 (95% CI 5 to 17). Comparisons of different anti-adhesion therapies following operative hysteroscopyIt was unclear whether there was a difference between the use of a device combined with graft versus device only for the outcome of ongoing pregnancy (OR 1.48, 95% CI 0.57 to 3.83; 180 women; 3 studies; I2 = 0%; low-quality evidence). There were fewer IUAs at second-look hysteroscopy using a device with or without graft/gel or gel combined with hormonal treatment and antibiotics compared with using a device only or hormonal treatment combined with antibiotics, but the findings of this meta-analysis were affected by evidence quality (OR 0.55, 95% CI 0.36 to 0.83; 451 women; 5 studies; I2 = 0%; low-quality evidence). AUTHORS' CONCLUSIONS: Implications for clinical practiceThe quality of the evidence ranged from very low to low. The effectiveness of anti-adhesion treatment for improving key reproductive outcomes or for decreasing IUAs following operative hysteroscopy in subfertile women remains uncertain. Implications for researchMore research is needed to assess the comparative safety and (cost-)effectiveness of different anti-adhesion treatments compared to no treatment or other interventions for improving key reproductive outcomes in subfertile women. PMID- 29178173 TI - Evaluation of apical transportation and centring ability of five thermally treated NiTi rotary systems. AB - AIM: To evaluate apical transportation and centring ability during root canal preparation in mesial root canals of mandibular molars associated with ProTaper Gold (PTG), ProDesign S (PDS), Hyflex CM (HCM), Hyflex EDM and ProDesign Logic (PDL). METHODOLOGY: Sixty mandibular first molars with two separate canals in the mesial root were selected after root anatomy pairing by microcomputed tomography (microCT). The teeth were randomly divided into five groups (n = 24); the root canal volume was calculated to ensure sample homogeneity. All the root canals were prepared up to size 25 in accordance with the instructions of each rotary system manufacturer. After root canal preparation, the teeth were scanned by microCT to analyse apical transportation, root canal centralization and the pre- and post-preparation root canal volume at the apical and cervical levels. Kruskal Wallis and Dunn tests were used for comparisons amongst groups for transportation values. For volume changes, the parametric ANOVA and Tukey's tests were used RESULTS: There were no significant differences in apical transportation amongst the rotary systems (P > 0.05). All the systems created apical transportation; values ranging from 0.031 mm (PDL) to 0.072 mm (PTG), and enlargements between 39% (HCM) and 91.1% (PDS) were observed. In relative to cervical transportation, significant differences were observed amongst the systems (P < 0.05). Mean transportation values between 0.07 mm (HCM) and 0.172 mm (PTG) were found, with enlargements between 35.4% (HCM) and 51.5% (PDS). CONCLUSION: All the thermally treated systems resulted in similar apical transportation. In the cervical region, the Hyflex CM and Prodesign Logic systems were associated with more centred preparations.

AB - OBJECTIVE: To explore the health education needs and learning preferences of female intimate partner violence (IPV) survivors in a social service agency located in South Florida, United States. DESIGN AND SAMPLE: An exploratory two phase sequential mixed-methods study was completed through semistructured interviews with social service providers (n = 10), followed by a survey with predominately female IPV survivors (n = 122, 98.4%). MEASURES: Data obtained from interviews with social service providers were analyzed through conventional thematic content analysis. Data from interviews were used in developing a health survey completed by IPV survivors and analyzed utilizing descriptive statistics, chi-square tests and t tests. RESULTS: Three themes emerged from interviews including multidimensional health needs, navigating barriers to health care, and self-improvement specific to survivors of intimate partner violence. Survey results indicated that depression and self-esteem were the health education needs of highest priority. Demographic characteristics, including age and language use, were significantly associated to preferred methods of learning, p < .05. CONCLUSIONS: IPV survivors present with various health education needs. Current study findings can inform public health nurses in developing interventions or health-based programs for female IPV survivors in social service agency settings. PMID- 29178175 TI - Effect of Dairy Cow Crossbreeding on Selected Performance Traits and Quality of Milk in First Generation Crossbreds. AB - : The main goal of crossbreeding Holstein-Friesian (HF) cows with bulls of other dairy or combined breeds is to improve their performance traits. Thus, the aim of this investigation was to compare the dairy performance traits of first generation crossbreds produced by crossbreeding Polish HF cows with bulls of other breeds (Norman, Norwegian Red, Danish Red, Brown Swiss, Montbeliarde, and Simmental). This was done by analyzing the fatty acid profile and technological quality of the milk from these first generation crossbreds. The investigation showed that crossbreeding greatly influenced the performance parameters and technological quality of the milk of the first generation crossbreds obtained from crossbreeding Polish HF cows with bulls of other dairy or combined breeds. The crossbreed cows characterized by the highest both quantity and quality of milk. Also, the best parameters of milk fat dispersion (that is, the highest values of these parameters) that are useful in the production of hard ripening cheeses and butter were found in the milk of crossbreed cows. Health beneficially, saturated fatty acids level in milk of crossbreeds was by 25.96% lower in crossbreds milk when compared to purebred cows. The most beneficial content of whey proteins was found in the milk of Polish HF and Norwegian Red crosses, where it was 19.04% higher than in pure breed Holsteins. F1 cows tend to express better functional traits than Holstein (PHF) cows. Effect of heterosis was larger and gave better results when there was a greater genetic distance between the animals used for crossbreeding. PRACTICAL APPLICATION: The effects of heterosis are opposite to the effects of inbreeding depression, and it extends the lifespan and use of animals as well as improves their fertility and health. The main goal of crossbreeding Holstein-Friesian cows with bulls of other dairy or combined breeds is to improve their performance traits. F1 cows tend to express better functional traits than Holstein (PHF) cows. Effect of heterosis was larger and gave better results when there was a greater genetic distance between the animals used for crossbreeding. PMID- 29178176 TI - Updated Estimates Suggest a Much Higher Prevalence of Arthritis in United States Adults Than Previous Ones. AB - OBJECTIVE: National estimates of arthritis prevalence rely on a single survey question about doctor-diagnosed arthritis without using survey information on joint symptoms, even though some subjects with only the latter have been shown to have arthritis. The sensitivity of the current surveillance definition is only 53% and 69% in subjects ages 45-64 years and ages >=65 years, respectively, resulting in misclassification of nearly one-half and one-third of subjects in those age groups. This study was undertaken to estimate arthritis prevalence based on an expansive surveillance definition that is adjusted for the measurement errors in the current definition. METHODS: Using the 2015 National Health Interview Survey, we developed a Bayesian multinomial latent class model for arthritis surveillance based on doctor-diagnosed arthritis, joint symptoms, and whether symptom duration exceeded 3 months. RESULTS: Of 33,672 participants, 19.3% of men and 16.7% of women ages 18-64 years and 15.7% of men and 13.5% of women ages >=65 years affirmed joint symptoms without doctor-diagnosed arthritis. The measurement error-adjusted prevalence of arthritis was 29.9% (95% Bayesian probability interval [95% PI] 23.4-42.3) in men ages 18-64 years, 31.2% (95% PI 25.8-44.1) in women ages 18-64 years, 55.8% (95% PI 49.9-70.4) in men ages >=65 years, and 68.7% (95% PI 62.1-79.9) in women ages >=65 years. Arthritis affected 91.2 million adults (of 247.7 million; 36.8%) in the US in 2015, which included 61.1 million persons between 18 and 64 years of age (of 199.9 million; 30.6%). Our arthritis prevalence estimate was 68% higher than the previously reported national estimate. CONCLUSION: Arthritis prevalence in the US population has been substantially underestimated, especially among adults younger than 65 years of age.

However, a substantial fraction of cargo in axons remains stationary up to several minutes. We examine the transport of precursors of synaptic vesicles (pre SVs), endosomes and mitochondria in Caenorhabditis elegans touch receptor neurons, showing that stationary cargo are predominantly present at actin-rich regions along the neuronal process. Stationary vesicles at actin-rich regions increase the propensity of moving vesicles to stall at the same location, resulting in traffic jams arising from physical crowding. Such local traffic jams at actin-rich regions are likely to be a general feature of axonal transport since they also occur in Drosophila neurons. Repeated touch stimulation of C. elegans reduces the density of stationary pre-SVs, indicating that these traffic jams can act as both sources and sinks of vesicles. This suggests that vesicles trapped in actin-rich regions are functional reservoirs that may contribute to maintaining robust cargo flow in the neuron.

AB - OBJECTIVES: The closure of atrial septal defect (ASD) results in normalized left ventricular (LV) and right ventricular (RV) geometry, and can increase LV stroke volume (LVSV), but the parameters associated with this increase after the closure of ASD remain uncertain. METHODS: Seventy ASD patients, who underwent transcatheter closure, were studied. Their mean age was 57.80 +/- 16.88 years, 42 (60%) were female, and LV ejection fraction (LVEF) was 66.76% +/- 7.91% (all >=55%). Transthoracic echocardiography was performed before and 3 months after the procedure. Global longitudinal strain (GLS) was determined as the average peak speckle tracking strain of 18 segments from the 3 standard apical views, LV dispersion was defined as standard deviation of time-to-peak strain from the same views, and RV systolic function was calculated by averaging the 3-regional peak speckle tracking longitudinal strains from the RV free wall. A significant relative increase in LVSV between before and 3 months after the closure was defined as ?LVSV >=15%. Twenty age-, gender-, and LVEF-matched controls served as the control group. RESULTS: Global longitudinal strain (GLS) and RV free wall strain were similar for ASD patients and controls, but LV dispersion in ASD patients was significantly larger. Global longitudinal strain (GLS) remained unchanged after transcatheter closure, whereas RV free wall strain and LV dispersion decreased significantly. An important finding of the multivariate logistic regression analysis showed that ?LV dispersion was the only independent determinant of increased LVSV after the closure (OR 1.023; 95% CI 1.001-1.046; P < .01). CONCLUSIONS: The assessment of LV dispersion may well have clinical implications for better management of ASD patients after transcatheter closure. PMID- 29178180 TI - High-density lipoprotein from end-stage renal disease patients exhibits superior cardioprotection and increase in sphingosine-1-phosphate. AB - BACKGROUND: Chronic kidney disease (CKD) exacerbates the risk of death due to cardiovascular disease (CVD). Modifications to blood lipid metabolism which manifest as increases in circulating triglycerides and reductions in high-density lipoprotein (HDL) cholesterol are thought to contribute to increased risk. In CKD patients, higher HDL cholesterol levels were not associated with reduced mortality risk. Recent research has revealed numerous mechanisms by which HDL could favourably influence CVD risk. In this study, we compared plasma levels of sphingosine-1-phosphate (S1P), HDL-associated S1P (HDL-S1P) and HDL-mediated protection against oxidative stress between CKD and control patients. METHODS: High-density lipoprotein was individually isolated from 20 CKD patients and 20 controls. Plasma S1P, apolipoprotein M (apoM) concentrations, HDL-S1P content and the capacity of HDL to protect cardiomyocytes against doxorubicin-induced oxidative stress in vitro were measured. RESULTS: Chronic kidney disease patients showed a typical profile with significant reductions in plasma HDL cholesterol and albumin and an increase in triglycerides and pro-inflammatory cytokines (TNF alpha and IL-6). Unexpectedly, HDL-S1P content (P = .001) and HDL cardioprotective capacity (P = .034) were increased significantly in CKD patients. Linear regression analysis of which factors could influence HDL-S1P content showed an independent, negative and positive association with plasma albumin and apoM levels, respectively. DISCUSSION: The novel and unexpected observation in this study is that uremic HDL is more effective than control HDL for protecting cardiomyocytes against oxidative stress. It is explained by its higher S1P content which we previously demonstrated to be the determinant of HDL mediated cardioprotective capacity. Interestingly, lower concentrations of albumin in CKD are associated with higher HDL-S1P.

AB - In this cross-sectional, descriptive study, we compared the sociodemographic characteristics, social networks, health-promoting behavior, and the health related quality of life of older Korean adults living in South Korea to those of older Korean adult immigrants living in the USA. A total of 354 older adults, aged 65 years or older, participated. Data were collected through self-directed questionnaires, and analyzed using a two way analysis of variance, t-tests, chi2 tests, and Pearson's correlation coefficient. The association between four sociodemographic characteristics and health-related quality of life was significantly different between the two groups. For the older Korean adults living in South Korea, positive correlations existed between a measure of their social networks and both health-promoting behavior and health-related quality of life. For the older Korean immigrants, the findings revealed a positive correlation only between social networks and health-promoting behavior. The study findings support the important association social networks can have with health related quality of life, and their possible relationship to health-promoting behaviors of older Korean adults. We suggest that health policy-makers and healthcare providers develop comprehensive programs that are designed to improve older adults' social networks. PMID- 29178183 TI - Predictors of an abnormal postexercise ankle brachial index: Importance of the lowest ankle pressure in calculating the resting ankle brachial index. AB - BACKGROUND: The postexercise ankle-brachial index (ABI) is useful in patients with suspected peripheral arterial disease (PAD) and a normal resting ABI. Our objective was to determine the independent predictors of an abnormal postexercise ABI. HYPOTHESIS: We hypothesized that the lowest ankle systolic pressure to calculate the resting ABI would be associated with an abnormal post-exercise ABI. METHODS: Among 619 consecutive patients referred for suspected PAD, we calculated the postexercise ABI in patients with a normal resting ABI. An ABI <0.90 at rest was considered abnormal. We investigated 3 definitions of an abnormal postexercise ABI, defined as either <0.90, or >5% or >20% reduction compared with rest. RESULTS: Using multivariate analysis, the lowest ABI (calculated using the lowest and not the highest ankle systolic pressure) was consistently the most powerful independent predictor of an abnormal postexercise ABI. Patients with an abnormal lowest resting ABI were significantly more likely to have an abnormal postexercise ABI, as well as a significantly greater reduction in the ABI compared with rest. The lowest ABI had a high specificity (95%) but low sensitivity (82%) for a postexercise ABI <0.90. CONCLUSIONS: An abnormal lowest ABI (calculated with the lowest ankle systolic pressure) is the most important independent predictor of an abnormal ABI response to exercise in patients with a conventionally normal ABI. All such patients should be exercised and their ABI measured postexercise. PMID- 29178184 TI - Anatomy of the pedicled anterolateral thigh flap for phalloplasty in transitioning-males. AB - Incidence of transexualism and request for neophalloplasty is increasing yielding a current prevalence of trans-male in the USA of 1:2500. Surgeons have explored various techniques to improve desirable outcomes of neophallic construction, decrease the length of surgery, and minimize stigmatizing scars. The anterolateral thigh (ALT) flap is an alternative to the traditional radial forearm flap for patients who do not want a forearm scar. Surgical text descriptions were enhanced by the creation of new anatomic illustrations. Anatomy of the donor and recipient sites as well as the surgical technique leading to creation of the neophallus are demonstrated in detail with new relevant illustrations. The ALT flap is a skin, fat and fascia flap that is usually supplied by the descending branch of the lateral circumflex femoral vessels and the lateral femoral cutaneous nerve. However, variability in neurovascular supply does exist with important clinical implications. In the pedicled surgical procedure, neurovascular supply is left partly attached to the donor site ("pedicle") and simply transposed to the perineum, keeping the pedicle intact as a conduit to supply the tissue with blood and innervation. ALT flap offers clinical advantages of less obvious donor site concealable with clothing, decreased surgical time, preservation of erogenous sensation and vascular supply of the flap without microsurgical anastomosis of nerves and vessels, and good potential for urethroplasty. This surgery may be difficult in patients with thicker skin and more subcutaneous thigh fat. Clin. Anat, 2017. (c) 2017 Wiley Periodicals, Inc. (c) 2017 Wiley Periodicals, Inc.

AB - OBJECTIVE: To report the outcomes of women with placenta percreta who were surgically treated by a specialized technique based on gynecologic oncology experience, and to demonstrate its safety in preventing ureteral lesions and reducing blood loss. METHODS: In the present retrospective study, data from patients with placenta percreta radically treated at Hotel-Dieu de France, Beirut, Lebanon, between December 2012 and January 2017 were reviewed. Demographic, pathology, and delivery data, medical history, per-operative and postoperative information, and neonatal data were assessed. Operative and postoperative outcomes were compared between emergency and scheduled cases. RESULTS: Data from 35 patients were reviewed. Median gestational age at delivery was 34 weeks. Cesarean hysterectomy was scheduled in 20 (60%) cases. No ureteral lesions were noted. The median estimated blood loss was 1 L and a median of 3 units of red blood cells units was transfused. Emergency and scheduled cases presented comparable estimated blood loss, intra-operative transfusion, bladder injury incidence, and surgery duration (all P>0.05). The mean delivery weight was 2100 g; admission to the neonatal intensive care unit was needed for 30 (86%) neonates. CONCLUSION: The surgical technique developed for placenta percreta was found to be effective (operative and postoperative outcomes) and safe (prevention of ureteral lesions). PMID- 29178188 TI - Characterization of the enzymatic activity and physiological function of the lipid droplet-associated triacylglycerol lipase AtOBL1. AB - Similar to seeds, pollen tubes contain lipid droplets that store triacylglycerol (TAG), but the fate of this TAG as well as the enzymes involved in its breakdown are unknown. Therefore, two potential TAG lipases from tobacco and Arabidopsis, NtOBL1 (Oil body lipase 1) and AtOBL1, were investigated, especially with respect to their importance for pollen tube growth. We expressed NtOBL1 and AtOBL1 as fluorescent fusion proteins to study their localization by confocal microscopy. Furthermore, we overexpressed AtOBL1 in Nicotiana benthamiana leaves to characterize it enzymatically. The obl1 mutant was studied in respect to its pollen tube growth in vivo and its seed germination. Both NtOBL1 and AtOBL1 localized to lipid droplets. AtOBL1 was abundant in pollen tubes and seedlings, and acted as a lipase on TAG, diacylglycerol and 1-monoacylglycerol at a pH optimum of 5.5. The obl1 mutant was hampered in pollen tube growth, whereas seedling establishment was not affected under optimal conditions, even though AtOBL1 accounted for a major lipase activity in seeds. TAG could be a direct precursor for the synthesis of membrane lipids in pollen tubes and proteins of the OBL family involved in the flux of acyl groups. PMID- 29178186 TI - Mammary epithelium-specific inactivation of V-ATPase reduces stiffness of extracellular matrix and enhances metastasis of breast cancer. AB - Extracellular matrix (ECM) critically impacts tumor progression and is influenced by both cancer and host tissue cells. While our understanding of cancer cell ECM remodeling is widespread, the importance of host tissue ECM, which provides initial congenial environment for primary tumor formation, is partly understood. Here, we report a novel role of epithelial cell-associated vacuolar ATPase 'a2' isoform (a2V) in regulating breast tissue ECM stiffness to control metastasis. Using a mammary gland-specific a2V-knockout model, we show that in the absence of a2V, breast tumors exhibit atypically soft tumor phenotype, less tumor rigidity, and necrotic tumor microenvironment. These tumors contain a decreased number of cancer cells at primary tumor site, but showed extensive metastases compared to control. Nanomechanical evaluation of normal breast tissues revealed a decrease in stiffness and collagen content in ECM of a2V-deleted breast tissues. Mechanistically, inhibition of a2V expression caused dispersed Golgi morphology with relocation of glycosyltransferase enzymes to early endosomes in mammary epithelial cells. This resulted in defective glycosylation of ECM proteins and production of compromised ECM that further influenced tumor metastasis. Clinically, in patients with cancer, low a2V expression levels in normal breast tissue correlated with lymph node metastasis. Thus, using a new knockout mouse model, we have identified a2V expression in epithelial cells as a key requirement for proper ECM formation in breast tissue and its expression levels can significantly modulate breast tumor dissemination. Evaluation of a2V expression in normal breast tissues can help in identifying patients with high risk of developing metastases. PMID- 29178189 TI - Toothbrushing behaviour and periodontal pocketing: An 11-year longitudinal study. AB - AIM: To explore the association between toothbrushing behaviour and change in periodontal pocketing among adults. METHODS: We pooled data from 1,025 adults, aged 30-89 years, who participated in two national surveys in Finland (Health 2000 and Health 2011, BRIF8901) and reported their toothbrushing frequency. A cumulative measure of regular toothbrushing was created by counting the number of times participants reported brushing twice or more daily across the two surveys (ranging from 0 to 2). The association between toothbrushing behaviour and the number of teeth with periodontal pocket depth (PPD) >=4 mm over 11 years was assessed in linear regression models adjusting for confounders. RESULTS: There was a clear dose-response relationship between toothbrushing frequency (either at baseline or follow-up) and change in number of teeth with PPD >= 4 mm. There was also evidence of a cumulative effect of regular toothbrushing on change in number of teeth with PPD >= 4 mm. Participants who reported brushing twice or more a day in both surveys developed 1.99 (95% CI: 1.02-2.95) fewer teeth with PPD >= 4 mm than those who did not report this behaviour in any survey. CONCLUSION: This 11 year prospective study showed that toothbrushing behaviour was associated with smaller increments in the number of teeth with periodontal pocketing.

AB - Bioinspiration, biomorphy, biomimicry, biomimetics, bionics, and biotemplating are terms used to describe the fabrication of materials or, more generally, systems to solve technological problems by abstracting, emulating, using, or transferring structures from biological paradigms. Herein, a brief overview of how the different terminologies are being typically applied is provided. It is proposed that there is a rich field of research that can be expanded by utilizing various novel approaches for the guidance of living organisms for "bio-mediated" material structuring purposes. As examples of contact-based or contact-free guidance, such as substrate patterning, the application of light, magnetic fields, or chemical gradients, potentially interesting methods of creating hierarchically structured monolithic engineering materials, using live patterned biomass, biofilms, or extracellular substances as scaffolds, are presented. The potential advantages of such materials are discussed, and examples of live self patterning of materials are given. PMID- 29178192 TI - Mutagenic primer-based PCR-RFLP assay for genotyping IRGM gene promoter variant rs4958843 (C/T). AB - BACKGROUND: Single-nucleotide polymorphisms play an important role in the susceptibility of many diseases, evolutionary studies, and genetic mapping. The rs4958843 in IRGM promoter is associated with tuberculosis and Crohn's disease. As this SNP is not present in any of the restriction sites, PCR-RFLP is not possible. Therefore, we have developed artificial-RFLP method to genotype this SNP. METHODS: We designed forward primer with mismatches that resulted in the creation of a restriction site for enzyme NheI in the amplicon. Control samples of known genotypes were obtained by sequencing. The amplified product for SNP rs4958843 was digested with NheI restriction enzyme and resolved on an agarose gel to know the genotypes of the samples. RESULTS: Results of sequencing and A RFLP were concordant. The developed method was applied to genotype this polymorphism in 100 samples from healthy individuals. The allelic frequencies of SNP rs4958843 were C (0.16) and T (0.84), while corresponding genotypic distribution was CC (2), CT (29), and TT (69). CONCLUSION: The newly developed method is simple, easy, and cost-effective which could be used to genotype IRGM polymorphism -1161 C/T (rs4958843) in various populations in the replication studies and has its applicability in the clinical settings. The developed method was applied for genotyping samples from healthy individuals from North India. For the first time, we report the frequency of this polymorphism from this region. PMID- 29178193 TI - Proteomic Characterization of Caenorhabditis elegans Larval Development. AB - The nematode Caenorhabditis elegans is widely used as a model organism to study cell and developmental biology. Quantitative proteomics of C. elegans is still in its infancy and, so far, most studies have been performed on adult worm samples. Here, we used quantitative mass spectrometry to characterize protein level changes across the four larval developmental stages (L1-L4) of C. elegans. In total, we identified 4130 proteins, and quantified 1541 proteins that were present across all four stages in three biological replicates from independent experiments. Using hierarchical clustering and functional ontological analyses, we identified 21 clusters containing proteins with similar protein profiles across the four stages, and highlighted the most overrepresented biological functions in each of these protein clusters. In addition, we used the dataset to identify putative larval stage-specific proteins in each individual developmental stage, as well as in the early and late developmental stages. In summary, this dataset provides system-wide analysis of protein level changes across the four C. elegans larval developmental stages, which serves as a useful resource for the C. elegans research community. MS data were deposited in ProteomeXchange (http://proteomecentral.proteomexchange.org) via the PRIDE partner repository with the primary accession identifier PXD006676.

AB - Specific clinical features of aplasia cutis congenita may indicate the presence of underlying cranial or cerebrovascular defects, allowing for early recognition and intervention. Most information about aplasia cutis congenita exists as individual case reports, with few large-scale studies. We conducted a 7-year retrospective chart review of 90 cases of aplasia cutis congenita and identified clinical characteristics including morphology, number of lesions, anatomic location, presence of hair collar sign, associated cutaneous features, histology, and imaging results. The anatomic location of the lesion (vertex, midline) (P = .01), presence of hair collar sign (P < .001), vascular stains (P < .001), and nodules (P = .007) were found to be strong clinical indicators of skull or cerebrovascular involvement.

AB - Edging closer towards developing air and moisture compatible polar organometallic chemistry, the chemoselective and ultrafast addition of a range of aryllithium reagents to nitriles has been accomplished by using glycerol as a solvent, at ambient temperature in the presence of air, establishing a novel sustainable access to aromatic ketones. Addition reactions occur heterogeneously ("on glycerol conditions"), where the lack of solubility of the nitriles in glycerol and the ability of the latter to form strong intermolecular hydrogen bonds seem key to favouring nucleophilic addition over competitive hydrolysis. Remarkably, PhLi exhibits a greater resistance to hydrolysis working "on glycerol" conditions than "on water". Introducing glycerol as a new solvent in organolithium chemistry unlocks a myriad of opportunities for developing more sustainable, air and moisture tolerant main-group-metal-mediated organic synthesis. PMID- 29178196 TI - Comparative transcriptomic analysis of larval and adult Malpighian tubules from the cotton bollworm Helicoverpa armigera. AB - Malpighian tubules (MTs) are usually considered the key excretory and osmoregulatory organs of insects. However, increasing evidence has suggested that MTs perform many more functions than just osmoregulation. Until now, the molecular and physiological functions of MTs in the cotton bollworm (Helicoverpa armigera), a very important agricultural pest, are largely unknown. In this study, the transcriptomes of H. armigera MTs from larvae, male adults and female adults were sequenced using RNA-Seq technology, and comparative analyses of transcriptomes between two life stages (larval and adult) and between adult sexes were conducted. We generated a total of 84 643 high-quality unigenes, and identified a large number of abundant transcripts putatively encoding proteins involved in diuresis, detoxification, immunity, carbohydrate transport and metabolism, development and reproduction. We found that the expression pattern of unigenes was relatively similar between female and male adult MTs, but different between larval and adult MTs. Our data suggest that insect MTs may take multiple physiological functions as versatile organs. The extensive alterations in gene expression in MTs occurred from larvae to adults reflect an ecological adaptation to different feeding habits. Sexual dimorphism in the cotton bollworm is somewhat indicated by the transcriptional difference of genes related to carbohydrate metabolism, detoxification, immunity and reproduction in the MTs of male and female adults. PMID- 29178197 TI - Greater retention in care among adolescents on antiretroviral treatment accessing "Teen Club" an adolescent-centred differentiated care model compared with standard of care: a nested case-control study at a tertiary referral hospital in Malawi. AB - INTRODUCTION: There are numerous barriers to the care and support of adolescents living with HIV (ALHIV) that makes this population particularly vulnerable to attrition from care, poor adherence and virological failure. In 2010, a Teen Club was established in Zomba Central Hospital (ZCH), Malawi, a tertiary referral HIV clinic. Teen Club provides ALHIV on antiretroviral treatment (ART) with dedicated clinic time, sexual and reproductive health education, peer mentorship, ART refill and support for positive living and treatment adherence. The purpose of this study was to evaluate whether attending Teen Club improves retention in ART care. METHODS: We conducted a nested case-control study with stratified selection, using programmatic data from 2004 to 2015. Cases (ALHIV not retained in care) and controls (ALHIV retained in care) were matched by ART initiation age group. Patient records were reviewed retrospectively and subjects were followed starting in March 2010, the month in which Teen Club was opened. Follow-up ended at the time patients were no longer considered retained in care or on 31 December 2015. Cases and controls were drawn from a study population of 617 ALHIV. Of those, 302 (48.9%) participated in at least two Teen Club sessions. From the study population, 135 (non-retained) cases and 405 (retained) controls were selected. RESULTS: In multivariable analyses, Teen Club exposure, age at the time of selection and year of ART initiation were independently associated with attrition. ALHIV with no Teen Club exposure were less likely to be retained than those with Teen Club exposure (adjusted odds ratio (aOR) 0.27; 95% CI 0.16, 0.45) when adjusted for sex, ART initiation age, current age, reason for ART initiation and year of ART initiation. ALHIV in the age group 15 to 19 were more likely to have attrition from care than ALHIV in the age group 10 to 14 years of age (aOR 2.14; 95% CI 1.12, 4.11). CONCLUSIONS: This study contributes to the limited evidence evaluating the effectiveness of service delivery interventions to support ALHIV within healthcare settings. Prospective evaluation of the Teen Club package with higher methodological quality is required for programmes and governments in low- and middle-income settings to prioritize interventions for ALHIV and determine their cost-effectiveness. PMID- 29178198 TI - Association between Helicobacter pylori infection and gallbladder diseases: A retrospective study. AB - BACKGROUND AND AIM: The association between Helicobacter pylori (H. pylori) and gallbladder diseases is still unclear and is controversial. We conducted a retrospective study to clarify the prevalence of gallbladder diseases and factors related to gallbladder diseases and relationships between H. pylori infection, gallstones, cholecystitis, and cholecystic polypus. METHODS: The retrospective study was performed at the Aerospace Center Hospital in Beijing. The subjects in this study were a healthy population who underwent health examinations at the hospital between 2012 and 2015. The logistic regression models were used to explore the relationships between H. pylori infection and gallbladder diseases. RESULTS: There were 7803 (43.4%) subjects with H. pylori infection, 995 (5.5%) with gallstones, 219 (1.2%) with cholecystitis, and 1003 (5.6%) with cholecystic polypus amongst 17 971 subjects, respectively. In subjects aged 45 years or less, the prevalence of gallstones in the H. pylori (+) group was lower than that in the H. pylori (-) group (odds ratio = 0.653; 95% confidence interval: 0.468 0.911; P = 0.012). The prevalence of cholecystic polypus in the H. pylori (+) group was significantly higher than that in the H. pylori (-) group (odds ratio = 1.160; 95% confidence interval: 1.012-1.328; P = 0.033). CONCLUSIONS: Helicobacter pylori infection was related with cholecystic polypus and gallstones in a Chinese population.

AB - The adult bone marrow (BM) niche is a complex entity where a homeostatic hematopoietic system is maintained through a dynamic crosstalk between different cellular and non-cellular players. Signaling mechanisms triggered by cell-cell, cell-extracellular matrix (ECM), cell-cytokine interactions, and local microenvironment parameters are involved in controlling quiescence, self-renewal, differentiation, and migration of hematopoietic stem/progenitor cells (HSPC). A promising strategy to more efficiently expand HSPC numbers and tune their properties ex vivo is to mimic the hematopoietic niche through integration of adjuvant stromal cells, soluble cues, and/or biomaterial-based approaches in HSPC culture systems. Particularly, mesenchymal stem/stromal cells (MSC), through their paracrine activity or direct contact with HSPC, are thought to be a relevant niche player, positioning HSPC-MSC co-culture as a valuable platform to support the ex vivo expansion of hematopoietic progenitors. To improve the clinical outcome of hematopoietic cell transplantation (HCT), namely when the available HSPC are present in a limited number such is the case of HSPC collected from umbilical cord blood (UCB), ex vivo expansion of HSPC is required without eliminating the long-term repopulating capacity of more primitive HSC. Here, we will focus on depicting the characteristics of co-culture systems, as well as other bioengineering approaches to improve the functionality of HSPC ex vivo. PMID- 29178200 TI - The interrupted learner: How distractions during live and video lectures influence learning outcomes. AB - New instructional technologies have been increasingly incorporated into the medical school learning environment, including lecture video recordings as a substitute for live lecture attendance. The literature presents varying conclusions regarding how this alternative experience impacts students' academic success. Previously, a multi-year study of the first-year medical histology component at the University of Michigan found that live lecture attendance was positively correlated with learning success, while lecture video use was negatively correlated. Here, three cohorts of first-year medical students (N = 439 respondents, 86.6% response rate) were surveyed in greater detail regarding lecture attendance and video usage, focusing on study behaviors that may influence histology learning outcomes. Students who reported always attending lectures or viewing lecture videos had higher average histology scores than students who employed an inconsistent strategy (i.e., mixing live attendance and video lectures). Several behaviors were negatively associated with histology performance. Students who engaged in "non-lecture activities" (e.g., social media use), students who reported being interrupted while watching the lecture video, or feeling sleepy/losing focus had lower scores than their counterparts not engaging in these behaviors. This study suggests that interruptions and distractions during medical learning activities-whether live or recorded-can have an important impact on learning outcomes. Anat Sci Educ 11: 366-376.

AB - The bony cranial structures of even-toed hoofed mammals are important for understanding ecology and behavior of ruminants. Horns, the cranial appendages of the family Bovidae, are covered in a layer of keratin that is often not preserved in the fossil record; however, this keratin sheath is intimately involved in the processes that influence horn shape evolution. To understand the relationship between these two components of horns, we quantified both core and sheath shape for four extant species using three-dimensional geometric morphometric analyses in separate, core- and sheath-specific morphospaces as well as a combined morphospace. We assessed correlations between the horn and sheath morphospaces using two-block partial least squares regression, a Mantel test of pairwise distances between species, and Procrustes ANOVA. We measured disparity in the combined morphospace as Procrustes distances between mean shapes of cores and sheaths within and between species and as Procrustes variance. We also tested whether core and sheath shapes could be discriminated by taxon with a canonical variate analysis. Results show that horn core and sheath morphospaces are strongly correlated. The differences in shape between a species' core and sheath were statistically significant, but not as great as those between the cores and sheaths of different species when close relatives were not considered, and core and sheath Procrustes variances are not significantly different within species. Cores and sheath shapes were highly identifiable and were assigned to the correct clade 93% of the time in the canonical variate analysis. Based on these tests, horn cores are distinguishable in geometric morphometric analyses, extending the possibility of using geometric morphometrics to study the ecology and evolution of bovid horns to the fossil record.

AB - To meet the increasing demands for portable and flexible devices in a rapidly developing society, it is urgently required to develop highly safe and flexible electrochemical energy-storage systems. Flexible lithium-oxygen batteries with high theoretical specific energy density are promising candidates; however, the conventional half-open structure design prevents it from working properly under water or fire conditions. Herein, as a proof-of-concept experiment, a highly safe flexible lithium-oxygen battery achieved by the synergy of a vital multifunctional structure design and a unique composite separator is proposed and fabricated. The structure can effectively prevent the invasion of water from the environment and combustion, which is further significantly consolidated with the help of a polyimide and poly(vinylidene fluoride-co-hexafluoropropylene) composite separator, which holds good water resistance, thermal stability, and ionic conductivity. Unexpectedly, the obtained lithium-oxygen battery exhibits superior flexibility, water resistance, thermal resistance, and cycling stability (up to 218 cycles; at a high current of 1 mA and capacity of 4 mA h). This novel water/fireproof, flexible lithium-oxygen battery is a promising candidate to power underwater flexible electronics.

AB - In transgender surgery, the ideal neophallus is one that: (a) is constructed using a reproducible procedure, (b) possesses tactile and erogenous sensation, (c) is large and rigid enough (naturally, or using a prosthesis) to permit penetrative intercourse, (d) leaves acceptable donor site morbidity, (e) results in esthetically satisfactory appearance, and (f) allows for voiding while standing. The musculocutaneous latissimus dorsi (MLD) flap has favorable results in the area of neophalloplasty. Among its advantages are acceptable donor site appearance, stiffness sufficient for intercourse, and esthetically satisfactory genital appearance. The anatomy of the MLD flap supports the creation of a neophallus for transsexual anatomy revision. Herein, we give an overview of the advantages and disadvantages of the procedure, and the anatomical details and surgical steps involved. Novel illustrations were created from standard surgical text descriptions to clarify this topic for surgical training and patient understanding and decision making. A review of the relevant literature regarding the anatomy, procedure development, and outcomes is presented. The MLD flap uses part of the latissimus dorsi muscle with branches of the thoracodorsal vessels and nerve to construct a neophallus. A thin strip of muscle around the pedicle is harvested, resulting in a slightly curvilinear scar. The blood supply is connected to the femoral artery and saphenous vein or the deep inferior epigastric artery and vein, while the nerve is connected to the ilioinguinal nerve or the obturator nerve. The MLD flap for neophalloplasty is a reliable graft with a well concealed scar and low donor site morbidity. Clin. Anat. 31:152 159, 2018. (c) 2017 Wiley Periodicals, Inc.

AB - OBJECTIVE: Chronic illness of a child puts healthy children of the family at risk of distress. Previous studies have demonstrated that healthy children's psychological symptoms can be reduced when the child knows more about the disease. So far, there is limited evidence of the effectiveness of psychoeducational interventions for healthy children. AIMS: To compare the effectiveness of an inpatient family-oriented rehabilitation program with vs without additional psychoeducational sessions for healthy children of families with children with cancer. PATIENTS AND METHODS: We performed a controlled study in 4 German family-oriented rehabilitation clinics. The outcomes of n = 73 healthy children (mean age: M = 9.55; SD = 3.14; range: 4-18), who participated in 5 additional psychoeducational sessions, were compared with the outcomes of n = 111 healthy children (mean age: M = 8.85; SD = 3.28; range: 4-17), who underwent the usual inpatient rehabilitation program. Primary outcomes were the healthy children's cancer-specific knowledge and their emotional symptoms. Secondary outcomes were family satisfaction and quality of life. RESULTS: Intention-to-treat analyses showed that both groups improved significantly from preintervention to postintervention. Improvements comprised knowledge about cancer (F(1,174) = 11.03, p < 0.001), self-reported emotional symptoms (F(1,135) = 31.68, p < 0.001), and parent-proxy-reported emotional symptoms (F(1,179) = 37.07, p < 0.001). The additional psycho-educational program did not significantly enhance the outcomes. The same pattern of significant improvement in both conditions emerged for all secondary outcomes. The immediate effects of the intervention persisted until 2 months after discharge from the rehabilitation program. CONCLUSIONS: Inpatient family-oriented rehabilitation is effective in improving multiple psychosocial outcomes of healthy children in families which have a child with cancer. Additional psycho-educational sessions did not show any substantial additional improvement.

AB - Trypanosoma brucei uses multiple mechanisms to evade detection by its insect and mammalian hosts. The flagellar pocket (FP) is the exclusive site of uptake from the environment in trypanosomes and shields receptors from exposure to the host. The FP neck is tightly associated with the flagellum via a series of cytoskeletal structures that include the hook complex (HC) and the centrin arm. These structures are implicated in facilitating macromolecule entry into the FP and nucleating the flagellum attachment zone (FAZ), which adheres the flagellum to the cell surface. TbSmee1 (Tb927.10.8820) is a component of the HC and a putative substrate of polo-like kinase (TbPLK), which is essential for centrin arm and FAZ duplication. We show that depletion of TbSmee1 in the insect-resident (procyclic) form of the parasite causes a 40% growth decrease and the appearance of multinucleated cells that result from defective cytokinesis. Cells lacking TbSmee1 contain HCs with aberrant morphology and show delayed uptake of both fluid-phase and membrane markers. TbPLK localization to the tip of the new FAZ is also blocked. These results argue that TbSmee1 is necessary for maintaining HC morphology, which is important for the parasite's ability to take up molecules from its environment.

AB - The aim of this work was to study the distribution of Phlebotominae (Diptera: Psycodidade) abundance in time and space in an area in northeastern Argentina with vector transmission of visceral and tegumentary leishmaniasis. For this, 51 households were selected using a 'worst scenario' criterion where one light trap was set during two consecutive nights in peridomiciles in the transitions between the four seasons, and the environment was surveyed simultaneously. The relationships of phlebotomine assemblage structure and the most abundant species with seasonality and environmental variables were evaluated using a canonical correspondence analysis and generalized linear mixed models, respectively. A total of 5110 individuals were captured. Lutzomyia longipalpis (Lutz & Neiva, 1912) and Nyssomyia whitmani (Antunes & Coutinho, 1939) were the most abundant species captured in all samplings (98.3% of the total capture). The period of highest abundance of Lu. longipalpis was early autumn, and it was distributed in the most urbanized areas. Nyssomyia whitmani occupied mainly the less urbanized areas, showing peaks of abundance in early spring and summer. Other species were captured in low numbers and showed seasonal-spatial variations similar to those of Ny. whitmani. We confirmed Leishmania spp. vector persistence throughout the year in spatial patches of high abundance even during the less favorable season. PMID- 29178207 TI - Bullous pemphigoid inguinalis?

AB - 2,6-Dicyano-4-nitroaniline and 2-cyano-4-nitroaniline (CNNA; 2-amino-5 nitrobenzonitrile) are potent mutagens in the Ames test, even though unsubstituted nitroanilines (NAs) are no more than weak mutagens. These compounds are putative reduction products of many commercial azo dyes, including Disperse Blue 165, Disperse Blue 337, Disperse Red 73, Disperse Red 82, Disperse Violet 33, and Disperse Violet 63. We have examined the mutagenicity in strains TA98 and YG1024 of a series of commercially-available isomers of CNNA, and some related compounds, to probe the relationship between structure and genotoxic activity in this class of compounds. The potentiating effect of the cyano substituent is seen in many cases; e.g. 2-amino-4-nitrobenzonitrile is a much more potent mutagen than 3-NA. 2,4-Dinitrobenzonitrile is also highly mutagenic. Possible mechanisms for the "cyano effect" are considered, with respect to the likely structures of cyanonitroaniline-DNA adducts and the roles of the enzymes (nitroreductase and acetyl CoA:arylamine N-acetyltransferase) believed to be involved in the activation of nitroaromatic compounds.

AB - CONTEXT: Case study research (CSR) is a research approach that guides holistic investigation of a real phenomenon. This approach may be useful in medical education to provide critical analyses of teaching and learning, and to reveal the underlying elements of leadership and innovation. There are variations in the definition, design and choice of methods, which may diminish the value of CSR as a form of inquiry. OBJECTIVES: This paper reports an analysis of CSR papers in the medical education literature. The review aims to describe how CSR has been used and how more consistency might be achieved to promote understanding and value. METHODS: A systematised review was undertaken to quantify the number of CSR articles published in scholarly medical education journals over the last 10 years. A typology of CSR proposed by Thomas and Myers to integrate the various ways in which CSR is constructed was applied. RESULTS: Of the 362 full-text articles assessed, 290 were excluded as they did not meet the eligibility criteria; 76 of these were titled 'case study'. Of the 72 included articles, 50 used single-case and 22 multi-case design; 46 connected with theory and 26 were atheoretical. In some articles it was unclear what the subject was or how the subject was being analysed. CONCLUSIONS: In this study, more articles titled 'case study' failed than succeeded in meeting the eligibility criteria. Well structured, clearly written CSR in medical education has the potential to increase understanding of more complex situations, but this review shows there is considerable variation in how it is conducted, which potentially limits its utility and translation into education practice. Case study research might be of more value in medical education if researchers were to follow more consistently principles of design, and harness rich observation with connection of ideas and knowledge to engage the reader in what is most interesting. PMID- 29178212 TI - Evolution of diastolic function algorithms: Implications for clinical practice. AB - OBJECTIVE: We undertook this study of echocardiographic classification of diastolic function by three different algorithms to determine: (1) how frequently each algorithm classified patients and (2) how well the results agreed with one another. BACKGROUND: Several algorithms exist to grade diastolic function (DF), the Mayo Clinic scheme of Redfield et al (Mayo 2003) and the 2 ASE guideline documents of 2009 and 2016 (ASE 2009 and ASE 2016). METHODS: A total of 200 consecutive echocardiograms were retrospectively analyzed; mean age of patients 60.3 +/- 3.5 years, 45% male. Echocardiograms were performed using Intersocietal Accreditation Commission guidelines. Diastolic function was assessed by Mayo 2003 and ASE 2009 and 2016. Coexisting conditions affecting DF analysis, such as mitral annular calcification (MAC), were tabulated. Data were compared using a paired t-test. Concordance between algorithms was assessed using the Kappa statistic. RESULTS: A total of 117 of 200 studies (58.5%) were excluded for the presence of coexisting conditions (51.5%), poor image quality (2.5%), or incomplete data (4.5%). Thirty-three of the remaining 83 studies (40%) received the same grade of DF based on assessments made using the Mayo 2003 and ASE 2016 algorithms; the Kappa statistic was 0.20. 36 of the 83 studies (43%) received the same grade of DF based on assessments made using the ASE 2009 and ASE 2016 algorithms; the Kappa statistic was 0.25. CONCLUSION: Assessment of diastolic function via echocardiography cannot be reliably accomplished in approximately 50% of patients using current guidelines. Further, when studies are suitable for assessment, widely used guidelines yield discordant results. PMID- 29178213 TI - Interprofessional collaboration between junior doctors and nurses in the general ward setting: A qualitative exploratory study. AB - AIM: To explore the collaboration experiences of junior physicians and nurses in the general ward setting. BACKGROUND: Junior physicians and nurses do not always work collaboratively and this could affect the quality of patient care. The understanding of the issues affecting junior physicians and nurses working together is needed to inform strategies to improve interprofessional collaboration. METHODS: Nineteen junior physicians and nurses were interviewed in 2012 and 2013. Interviews were transcribed and analysed using thematic analysis. RESULTS: Junior physicians and nurses acknowledged the importance of working collaboratively to achieve better patient care, but they are struggling to cope due to heavy clinical workload, organisational constraints and differing power relationships. Nurses have to take on more responsibilities in the decision making process of patients' care to foster effective interprofessional collaboration. CONCLUSION: The study calls for educational and organisational strategies to improve interprofessional collaboration between junior physicians and nurses. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse leaders should ensure that ward nurses are given a designated time to participate in ward rounds with physicians and have access to a communication tool that assists them in contributing proactively in the decision-making process of patient care. PMID- 29178214 TI - Redox Mediators for Li-O2 Batteries: Status and Perspectives. AB - Li-O2 batteries have received much attention due to their extremely large theoretical energy density. However, the high overpotentials required for charging Li-O2 batteries lower their energy efficiency and degrade the electrolytes and carbon electrodes. This problem is one of the main obstacles in developing practical Li-O2 batteries. To solve this problem, it is important to facilitate the oxidation of Li2 O2 upon charging by using effective electrocatalysis. Using solid catalysts is not too effective for oxidizing the electronically isolating Li-peroxide layers. In turn, for soluble catalysts, red ox mediators (RMs) are homogeneously dissolved in the electrolyte solutions and can effectively oxidize all of the Li2 O2 precipitated during discharge. RMs can decompose solid Li2 O2 species no matter their size, morphology, or thickness and thus dramatically increase energy efficiency. However, some negative side effects, such as the shuttle reactions of RMs and deterioration of the Li-metal occur. Therefore, it is necessary to study the activity and stability of RMs in Li-O2 batteries in detail. Herein, recent studies related to redox mediators are reviewed and the mechanisms of redox reactions are illustrated. The development opportunities of RMs for this important battery technology are discussed and future directions are suggested.

AB - Aortic insufficiency following left ventricular assist device implantation (LVAD) has been reported in up to 40% of patients and is associated with a worse prognosis.

PMID- 29178217 TI - Conformers of Saturated Chains: Matrix Isolation, Structure, IR and UV Spectra of n-Si4 Me10. AB - Infrared and ultraviolet spectra of the gauche and anti conformers of matrix isolated permethyl-n-tetrasilane have been obtained separately by taking advantage of thermally induced gauche-to-anti conversion and of wavelength selective photochemical destruction of either conformer. The resolved UV spectrum of the gauche conformer provides the first piece of experimental evidence in favor of the recently proposed reinterpretation of conformational effects on tetrasilane electronic states. According to this, it is not the energy but the intensity of the lowest singlet excitation that changes dramatically as the SiSiSiSi dihedral angle is varied, as a result of an avoided crossing between ss* and spi* states. Implications for the general understanding of sigma conjugation in simple terms are discussed. Unconstrained MP2/6-31 G* optimization predicts the existence of a third backbone conformer (ortho), with a dihedral angle of about 90 degrees . Its predicted (HF/3-21 G*) mid-IR spectrum is indistinguishable from that of the gauche conformer, and the matrix-isolation spectra thus provide no evidence for or against its presence. PMID- 29178216 TI - Diagnostic utility of surgical lung biopsies in elderly patients with indeterminate interstitial lung disease. AB - BACKGROUND AND OBJECTIVE: Idiopathic pulmonary fibrosis (IPF) is increasingly diagnosed by clinical and computed tomography (CT) criteria; however, surgical lung biopsy (SLB) may still be required in patients who lack definite CT features of usual interstitial pneumonia (UIP). We reviewed a cohort of elderly patients who underwent SLB, to evaluate the benefit of SLB in diagnosing idiopathic interstitial pneumonia (IIP). METHODS: We searched the pathology records of Mayo Clinic for ambulatory patients at least 75 years old, who underwent SLB between 2000 and 2012 for indeterminate IIP. Histologic slides were reviewed and clinical data were extracted from the record. RESULTS: A total of 55 patients (35 male) were enrolled. Median (interquartile range) age was 77 (76-80) years. Forced vital capacity was 70 (61-76)% and diffusing capacity of the lungs for carbon monoxide was 48 (42-54)% of predicted. In total, 37 (67%) patients had IPF, including 61% of those with HRCT findings inconsistent with UIP. Thirty-day mortality was 10% and 90-day mortality was 15%. CONCLUSION: The high mortality rate of SLB complicates the risk-benefit analysis in elderly patients with IIP. The expected value of the SLB is probably highest when the HRCT features are inconsistent with UIP, due to the frequent (39%) retrieval of patterns other than UIP.

AB - The reaction of [Rh(eta3 -C3 H5 )-(PiPr3 )2 ] (1) with HC?C?CH(Ph)OH yields the alkynyl(vinylidene) complex trans-[Rh{C?C?CH(Ph)OH}{?C?CH-CH(Ph)OH}(PiPr3 )2 ] (2), while from 1 and HC?C?CPh2 OH the alkynyl-(enyne)metal derivative trans [Rh(C?C?CPh2 OH){n2 -(E)-Ph2 (OH)C?C?C?CH?CH-CPh2 OH} (PiPr3 )2 ] (3) is obtained. On treatment with 1-alkyn-3-ols HC?C?CR2 OH (R = Me, Ph, iPr), the highly reactive pi-benzyl compound [Rh(n3 -CH2 Ph)(PiPr3 )2 ] (4) yields the five coordinate complexes [RhH(C?C?CR2 OH)2 (PiPr3 )2 ] (5-7) of which those with R = Me and Ph can be converted to the alkynyl(vinylidene)metal isomers trans [Rh(C?C?CR2 OH)(?C?CH-CR2 OH)-(PiPr3 )2 ] (8, 9). Compounds 8 and 9 react with L' = CO and isocyanides by migration of the alkynyl ligand to the vinylidene unit to give the enynylrhodium(I) complexes trans-[Rh{n1 -(Z)-C(C?C?CR2 ?OH)?CH-CR2 OH}(L')(PiPr3 )2 ] (10, 11: L' = CO; 12-15: L' = CNR'). Cleavage of the Rh-C s bond of 10 with CF3 -CO2 H affords trans-[Rh(n1 -O2 CCF3 )-(CO)(PiPr3 )2 ] (16) and the enyne (E)-Me2 (OH)C?C?C?CH?CH-CMe2 OH (17). Compounds 5-7 react with L' = CO and isocyanides to give the octahedral 1:1 adducts [RhH(C?C?CR2 OH)2 (L')(P iPr3 )2 ] (18-20 and 24-27), of which the CO derivatives 18-20 readily eliminate HC?C?CR2 OH to yield trans-[Rh-(C?C?CR2 OH)(CO)(PiPr3 )2 ] (21-23). On treatment of 6 or 9 (R = Ph) with Al2 O3 in the presence of chloride ions, besides trans [RhCl(?C?C?CPh2 )(P-iPr3 )2 ] (28) the hexapentaenerhodium(I) complex trans [RhCl(n2 -Ph2 C?C?C?C?C?CPh2 )(PiPr3 )2 ] (29) is formed. The kinetically preferred isomer trans-[RhCl(n2 -Ph2 C?C?C?C?C?CPh2 )(P-iPr3 )2 ] (33) has been prepared from [RhCl(PiPr3 )2 ]2 and Ph2 C?C?C?C?C?CPh2 ; it rearranges smoothly at room temperature to the thermodynamically more stable isomer 29. The molecular structures of 7 and 29 have been determined. PMID- 29178220 TI - Stabilization of Octahedral Thorium Clusters by Interstitial Hydrogen.

Both compounds form a body-centered cubic structure of octahedral cluster units with five or seven hydrogen atoms in eight disordered positions above the faces of the octahedron. The chemical bonding in these diamagnetic compounds has been analyzed: the simple counting rules for octahedral cluster compounds are fulfilled, and MO and band structure calculations confirm the hydridic nature of the bonding.

AB - Secondary phosphines such as HPPh2 and to the cationic iron dienyl complex [eta5 (1R)-ethylnopadienyl)Fe-(CO)3 ]+ (1) by nucleophilic addition. The phosphonium salt initially formed is readily deprotonated to yield an optically active tertiary phosphine [(n4 -(1 R)-ethylnopadienePPh2 )Fe(CO)3 ] (2b). A similar reaction also occurs with [C6 H7 Fe-(CO)3 ]+ (3) and [C7 H9 Fe(CO)3 ]+ (4) to give [(C6 H7 PPh2 )Fe(CO)3 ] (5) and [(C7 H9 PPh2 )Fe(CO)3 ] (6) in good yields. The mechanism of formation of these novel phosphines is discussed. Complex 2 b crystallizes in the space group P21 21 21 (no. 19); 5 crystallizes in the space group P21 /c (no. 14). Like other monodentate optically active phosphines, 2 b is capable of coordinating to transition metal complexes. It forms palladium complexes on reaction with [{MU-chloro(allyl)palladium}2 ] as well as with [{MU chloro[(N,N-dimethylamino-kN-2-methyl)phenyl-kC]palladium}2 ] (11). The latter reaction product crystallizes in the space group P31 (no. 144). PMID- 29178222 TI - Multinational Papers in the Front Row.

AB - Methyl 5'-thio-alpha-isomaltoside (1), which contains the ring-sulfur analogue of the nonreducing glucoside of isomaltose, was synthesized from gentiobiose through a novel ring opening-recyclization approach. The nonreducing glucoside of per-O benzylated phenyl 1-thio-beta-gentiobioside underwent O-5'-C-1' bond cleavage with dimethyl-boron bromide and thiolacetic acid to give the acyclic monothioacetal 4 with the 1-thioglucopyranoside at the reducing end intact. The HO-5' group in 4 was inverted by a standard oxidation-reduction process with good efficiency. Recyclization under Mitsunobu condition allowed C-5'-S-1' bond formation with inversion of configuration at C-5', to give 1 after functional group interconversion. TLC analysis showed that 1, unlike isomaltose, was not hydrolyzed by glucoamylase from Rhizopus niveus. A fluorometric assay confirmed that the dissociation constant (Kd ) for 1 with the enzyme was 39 mM at 20 degrees C, which is comparable with that for isomaltose. A binding assay involving fluorescence titration of the enzyme-1 complex with gluconolactone indicated that the disaccharide 1 was bound to the catalytic and noncatalytic subsites. Since isomaltose is known to bind only to the noncatalytic subsites, this result indicates a relatively high affinity of the 5-thioglucose moiety for the catalytic subsite. PMID- 29178224 TI - C-Disaccharides of Ketoses. AB - Reaction of gluconolactone 2 with allylmagnesium bromide at low temperatures afforded ketopyranose 3, which could easily be converted into open-chain ketoses (R)-6 and (S)-6. Their reaction with lithioacetylide 9 afforded propargylic alcohol derivatives (R)-10 and (S)-10, which could not be cyclized directly to the desired C-ketosides. They were converted by standard procedures into (R)-14 and (S)-14 and then into dicobalthexacarbonyl complexes (R)-16 and (S)-16. A facile acid-catalyzed ring closure gave the desired C-ketosides (R)-18 alpha/beta and (S)-18alpha/beta, respectively, in different ratios. In order to demonstrate that removal of the protective groups and hydrogenation of the CC triple bond proceed smoothly, (R)-18 alpha was transformed into the deprotected target molecule (R)-1 alpha. For the assignment of the new chiral centers at C-2/2' and at C-8, (S)-18alpha was transformed into azido derivative (S)-22alpha, which underwent intramolecular cycloaddition to afford the spiro derivative (S) 25alpha. Because of the conformational constraints in this molecule, unequivocal configurational assignment was possible with the help of NMR data. PMID- 29178225 TI - Emission from Zeolite-Occluded Manganese-Diimine Complexes. AB - Manganese complexes of 2,2'-bipyridine (bpy) and 1,10-phenantroline (phen) have been synthesised in the supercages of cubic NaX and NaY and in the hypercages of the hexagonal NaEMT faujasites. The coordination and redox chemistry were studied with ESCA, CA, FT-IR, FT-Raman, diffuse reflectance and emission techniques. FT IR/FT-Raman shows cis coordination for all complexes and a high Mn-N stretching frequency in the phen complexes as a result of steric constraints imposed by the ligand. [Mn(bpy)2 ]2+ in the different zeolites shows metal-to-ligand charge transfer (MLCT; at 495 nm); for [Mn(phen)2 ]2+ -NaY the MLCt is broadened owing to complex distortion. On MLCT excitation [Mn(bpy)2 ]2+ complexes show an ipsochromic shift in the emission and an increase in quantum yield with increasing steric restrictions imposed by the zeolite. The ipsochromic shift of the emission band of [Mn(phen)2 ]2+ in NaY results from the combined effect of the ligand field (this suggests emission from a CT state) and of coordinative distortion. The key factor influencing the emission properties is found to be the overall matrix-induced complex distortion. Cation stabilisation of the ligand anion affects emission indirectly. The decay times for [Mn-(bpy)2 ]2+ -NaY are in the millisecond range (7.5-11.5 ms). A proposed model for excitation and emission properties of zeolite-occluded MnII complexes involves excitation of a quartet CT state, intersystem crossing and subsequent emission. The enhanced stability of the coordination sphere in the zeolite allows complexes to luminesce from a CT state, which is not detected in solution. The zeolite behaves as a supramolecular cryptating agent, protecting complexes from photodissociation. PMID- 29178226 TI - Conformational Preference of 2-(Halomethyl)- and 2-(Oxymethyl)Pyridines: Microwave Spectrum, Ab Initio, and MM3 Studies of 2-(Fluoromethyl)Pyridine. AB - One single conformer was assigned from the microwave spectrum of 2 (fluoromethyl)pyridine, investigated in the gas phase in the 26.0-39.0 GHz spectral region at about -10 degrees C. Its Calpha-F bond was found to be coplanar with the ring and anti to the N-C2 bond (syn to the C2-C3 bond). There was no indication in the microwave spectrum of the presence of other rotameric forms of the molecule. The results of the spectroscopic study were backed up by ab initio calculations at the MP2/6-31 G** (frozen core) level. These calculations predict that the assigned conformer is the only stable form of the molecule. The transition state was calculated to have the CH2 F group 180 degrees from the stable anti conformation. The energy of the transition state was computed to be 20.2 kJ mol-1 higher than the energy of the anti rotamer. The results are interpreted in terms of a stereoelectronic effect, and the orbital overlaps responsible for the observed effect are discussed. It is shown that 2 (fluoromethyl)pyridine serves as a good model for 2-(alkoxymethyl)pyridines, previously found to show the same conformational preference. PMID- 29178227 TI - [Lithium tert-butylperoxide]12 : Crystal Structure of an Aggregated Oxenoid. AB - The X-ray crystal structure of the dodecameric lithium tert-butylperoxide [2]12 is the first of an alkali or alkaline earth peroxide. It shows the lithium ion bridging the two oxygen atoms of the peroxide unit and a slight lenghtening of the O-O bond, in agreement with quantum-chemical calculations. A calculation for the model reaction of MeLi with LiOOH to give MeOLi and LiOH reveals the importance of Li bridging the O-O bond in the transition state of this reaction, as similarly discussed for many oxidation reactions of (transition-) metal peroxides. Preliminary theoretical studies of the O-O bond length (and thus of the oxenoid character) as a function of the aggregation of 2 disclose that increasing aggregation leads to stabilization of the charge at the anionic oxygen atom and thus to a reduction of the O-O bond length (oxenoid character). Related considerations of the effect of aggregation should also be valid for other lithium (organometallic) compounds and their structure and reactivity as well as other properties.

AB - A variety of chiral, nonracemic 2-alkoxy-1-alkynylcyclopropanes 7 were synthesized in good to very good yields from enantiomerically pure glycidol derivatives (glycidol tosylate, epichlorohydrin) by boron trifluoride promoted addition of lithium trimethylsilylacetylide followed by protection of the secondary hydroxyl group and finally a diastereoselective gamma-elimination. The 2-ethoxy derivative (S,R)-7 b was deprotonated with n-butyllithium, and the resulting 1-lithio-2-ethoxy derivative (S,R)-20 functionalized by treatment with oxygen followed by tosyl chloride. Protodesilylation and catalytic hydrogenation smoothly furnished 1-ethenylcyclopropyl sulfonates, which underwent a clean Pd0 catalyzed SN 2'-type substitution with dimethyl propargylsodiummalonate to give the (E)-configurated enyne (R,E)-26 with a methylenecyclopropane end group. A diastereoselective Pauson-Khand reaction completed the sequence to give the enantiomerically pure spirocyclopropaneannelated bicyclo[3.3.0]octane derivative 31.

AB - Gaseous FCO+ ions from the ionization of mixtures of nitrogen trifluoride and carbon monoxide execute selective and efficient CO-functionalization of the C-H bonds of benzene and toluene and of the N-H bond of ammonia. The occurrence of these carbonylation reactions has been unambiguously ascertained by Fourier transform ion cyclotron resonance (FT-ICR) spectrometry, and the details of the structure and the mechanism of formation of the precursor FCO+ ions have been investigated. FT-ICR experiments show that these ions, structurally assigned as F C-O+ by collisionally activated dissociation (CAD) spectrometry, arise from the reaction of CO.+ with NF3 and of NF+2 with CO. Combining the latter F+ transfer with the independently observed fluoride-ion abstraction by FCO+ from NF3 results in a catalytic cycle in which gaseous NF+2 ions promote the conversion of carbon monoxide into carbonic difluoride, F2 CO, with nitrogen trifluoride as the source of F.

AB - An efficient polycondensation-cyclization approach to the synthesis of cyclodextrin analogues is demonstrated by the preparation of cyclohexaoside 1 and cyclooctaoside 2. The key intermediate, disaccharide 3, bearing the cyanoethylidene group as a glycosyl donor function and the trityloxy group as a glycosyl acceptor function was prepared in 15 steps starting from L-rhamnose and D-mannose. The crucial cyclooligomerization of the disaccharide monomer 3 was carried out in the presence of TrClO4 as a promoter with the use of ultra-dry conditions at normal concentrations. This reaction led to formation of the cyclic oligosaccharides 28 and 29 (in 34 and 31% yield, respectively), which were deprotected to afford 1 and 2, respectively. The X-ray crystal structural analysis of the cyclooctaoside 2 reveals a cylindrical shape for the cyclic oligosaccharide with C4 symmetry. Individual molecules of 2 are arranged perfectly in stacks that form nanotubes in the solid state.

AB - We report on the gas phase reactions of small Fe+n clusters (n = 2-10) with O2 , N2 O and CO2 in an FT-ICR mass spectrometer. Under our experimental conditions, clusters of all sizes reacted readily with O2 and all but the dimer reacted with N2 O. Only the smallest Fe+n clusters (n = 2-4) appeared to activate CO2 . For all X-O molecules (X = O, N2 , CO), reaction pathways were observed that include the transfer of O atoms. In addition, the reactions with O2 and N2 O were accompanied by the loss of one or two Fe atoms. Thermochemical considerations based upon the well-known X-O bond energies were used to calculate Fen -O+ bond dissociation energies (BDEs) for sizes n = 2-6; these amount to roughly 550 kJ mol-1 and thus are considerably higher than the BDE of the Fe-O+ ion. All oxidation reactions of the Fe+n clusters (n = 2-6) studied in more detail were terminated by products of Fex Ox+ stoichiometry (x = 1-4). These "microoxides of iron" are not able to activate any further X-O bonds. Secondary reactions of Fex Ox+ clusters with C6 H6 , C2 H4 and NH3 were investigated for two selected sizes (x = 2, 3) and compared with reactions of the naked Fe+n clusters.

AB - High-resolution gas chromatographic separation of all diastereomeric monomethyl substituted cyclohexyl nitrates is shown on a nonpolar methylpolysiloxane stationary phase, and the first application of this procedure to the environmental diastereomeric analysis of alkyl nitrates is presented. Two characteristic signals in the achiral analysis of atmospheric samples could be assigned to the smallest alkyl nitrate containing two asymmetric carbon atoms, 3 methyl-2-pentyl nitrate. Retention indices in the temperature-programmed separation based on the n-alkanes were determined. The homologous series of 1 alkyl nitrates were found to be useful as ECD-visible n-alkanes. Enantiomeric separation of alkyl nitrates was achieved on heptakis(3-O-acetyl,-2,6-di-O pentyl)-beta-cyclodextrin (LIPODEX-D). The influence of the nitrooxy group and the alkyl chain length on the chiral discrimination on LIPODEX-D is discussed for 25 chiral alkyl nitrates. The absolute configurations of some alkyl nitrates were assigned by asymmetric synthesis of enantiomerically pure references. The complexity of the alkyl nitrate mixtures present in air samples does not allow a direct chiral separation as the alkyl nitrates partly coelute on the LIPODEX-D column. Column coupling of LIPODEX-D with a polar achiral stationary phase like polyalkylenglycol (PAG) was successfully applied to solve this problem, and the chiral alkyl nitrates present in a typical air sample were separated. A systematic nomenclature for alkyl nitrates is introduced to handle the steadily growing number of branched and long-chain alkyl nitrates detected in environmental analysis.

AB - The addition product of sodium hydride and the 2,3-dihydro-1,3-diborole (CiPr)2 (BEt)2 CHMe (3c) reacted with [{(C5 Me5 )FeCl}x ] to produce the green sandwich complex [(C5 Me5 )Fe{n5 -(CiPr)2 (BEt)2 CMe}] (2 c), which formally contains 16 valence electrons (VE). Complex 2c has unexpected structural properties in the solid state: the 1,3-diborolyl ring is extremely folded (41 degrees ), and the Fe C2 distance is short (1.90 A). Analogously, violet Ru complexes 4a,c,d were obtained from 3a,c, NaH or tBuLi, and [{(C5 Me5 )RuCl}4 ]. With the less bulky heterocycles 3 b,e the new 30 VE triple-decker complexes [(C5 Me5 )Ru{MU,n5 -(CR1 )2 (BR2 )2 CMe}RuH(C5 Me5 )] (5b,e) were formed, which contain a Ru-H bond. Cyclic voltammetric studies revealed the existence of stable anions 2c- and 4d- formed by reversible one-electron reduction at -1.26 and -1.40 V, respectively (vs. SCE). The red-brown anions were further characterized by ESR spectroscopy following stepwise reduction of the neutral species with potassium in THF. Addition of CO to 4a and 4d led to formation of the monocarbonyl complexes [(C5 Me5 )Ru(CO){n5 -(CR1 )2 -(BR2 )2 CMe}] (6a,d), and 6d was characterized by X-ray structure analysis. The heterocycle in 6d is less folded (19 degrees ) than in 2 c. Its CO ligand causes a 28.5 degrees tilt of the cyclic ligands. Reaction of CO with 2 c yielded a red product of unknown structure. The electronic structure of 2 was studied by EH-MO theory, which revealed a unique bonding in the sandwich. The s electron density of the B-C bonds participates in the bonding to the iron atom; this demonstrates that the number of bonding electrons is the same as in ferrocene. Thus, the complexes 2 actually have 18 VE. PMID- 29178234 TI - The Pagodane -> Dodecahedrane Concept-Shorter Routes, Higher Yields. AB - Two variants of the "SN 2 route" from pagodanes (A, B) to functionalized dodecahedranes (D, F) and particularly dodecahedradienes (E) offer considerable improvements in the number of operations (from nine to five to three) and yields (e.g., for diester F from 55-65 to 70-75 to 85-91%). Key steps are the regio- and stereospecific introduction of four to six bromine substituents into dimethyl pagodane-4-syn,9-syn-dicarboxylate (1 b) and a highly complex (thirteen bond breaking/bond-forming events in four participating structures). yet very convenient (one-pot operation) and extremely efficient (nearly quantitative) transformation of secopagodane to bissecododecahedradiene with complete stereocontrol in transannular CH2 functionalizations. The prohibitively low kinetic acidity of "caged" hydrogens has so far only been overcome with the recently reported P2 F reagent (Schwesinger). Further improvement of the overall economy of the pagodane -> dodecahedrane scheme has been achieved by efficiently channeling a byproduct of the pagodane synthesis (ca. 10%) back into the SN 2 track. PMID- 29178235 TI - Validation of a simultaneous method for determining polycyclic aromatic compounds and alkylated isomers in biota. AB - RATIONALE: There is a need for a validated method to improve detection limits and simultaneously quantify polycyclic aromatic compounds (PACs, both parent and alkylated homologues) in biota by gas chromatography/tandem mass spectrometry because of their environmental significance. The validation of the method was performed in accordance to the Eurachem Guide to Quality in Analytical Chemistry. METHODS: Gas chromatography coupled with a triple quadrupole mass spectrometer used in multiple reaction monitoring (MRM) mode was used for detection and quantification. Retention time windows and selective MRM ion transitions were optimized for a suite of PACs. The developed method was validated by comparing our measurements made on a reference material of freeze-dried mussel tissue (Mytilus edulis) with the certified values. RESULTS: Linearity was observed between 10-1000 pg/MUL (PAHs) and 2-500 pg/MUL (alkyl-PACs including S-based PACs). The overall mean (+/-SD) for the limits of detection of 43 PACs studied were 0.305 +/- 0.276 and 2.69 +/- 1.10 ng/g, respectively. For the 14 certified target analytes, the percent relative error ranged from 1.3 to 33%. With the exception of benzo(a)pyrene, the between-day and within-day repeatability for all target analytes was lower than 15% RSD. CONCLUSIONS: This is the first report of a fully validated method to simultaneously quantify PACs in biota performed in an ISO accredited laboratory. PMID- 29178236 TI - Prevalence, predictors and challenges of gestational diabetes mellitus screening among pregnant women in northern Tanzania. AB - OBJECTIVES: To determine the prevalence and predictors of gestational diabetes mellitus (GDM) as well as acceptability of returning for glucose tolerance testing among pregnant women in Moshi municipality, northern Tanzania. METHODS: Cross-sectional study from October 2015 to April 2016 among women with gestation age of 24-28 weeks of pregnancy attending at Kilimanjaro Christian Medical Centre (KCMC) referral hospital, Majengo and Pasua Health Centres. Women were interviewed and requested to return the next day (window within a month, depending on gestational age) for fasting plasma glucose (FPG) testing, followed immediately by a 75 g oral glucose tolerance test (OGTT). GDM was diagnosed using the 2013 WHO criteria. Logistic regression was conducted to reveal independent predictors for GDM. RESULTS: Of 433 interviewed women, 100 (23%) did not return for FPG and OGTT testing. The prevalence of GDM among the 333 screened women was 19.5%, and 3% had diabetes in pregnancy (DIP). GDM was significantly associated with age >=35 years (adjusted OR 6.75), pre-pregnancy obesity (AOR 2.22) and history of abortion (AOR 2.36). CONCLUSION: Prevalence of GDM is high in Moshi. We recommend introduction of routine screening for hyperglycaemia during pregnancy along with strategies for follow-up to prevent long-term effects of GDM and DIP in women and their children.

AB - Diet and immunity are both highly complex processes through which organisms interact with their environment and adapt to variable conditions. Parents that are able to transmit information to their offspring about prevailing environmental conditions have a selective advantage by 'priming' the physiology of their offspring. We used a meta-analytic approach to test the effect of parental diet on offspring immune responses. Using the geometric framework for nutrition (a method for analysing diet compositions wherein food nutrient components are expressed as axes in a Cartesian coordinate space) to define dietary manipulations in terms of their energy and macronutrient compositions, we compiled the results of 226 experiments from 38 published papers on the intergenerational effects of diet on immunity, across a range of study species and immunological responses. We observed intergenerational impacts of parental nutrition on a number of offspring immunological processes, including expression of pro-inflammatory biomarkers as well as decreases in anti-inflammatory markers in response to certain parental diets. For example, across our data set as a whole (encompassing several types of dietary manipulation), dietary stress in parents was seen to significantly increase pro-inflammatory cytokine levels measured in offspring (overall d = 0.575). All studies included in our analysis were from experiments in which the offspring were raised on a normal or control diet, so our findings suggest that a nutrition-dependent immune state can be inherited, and that this immune state is maintained in the short term, despite offspring returning to an 'optimal' diet. We demonstrate how the geometric framework for nutrition can be used to disentangle the role that different forms of dietary manipulation can have on intergenerational immunity. For example, offspring B-cell responses were significantly decreased when parents were raised on a range of different diets. Similarly, our approach allowed us to show that a parental diet elevated in protein (regardless of energy composition and relative to a control diet) can increase expression of inflammatory markers while decreasing B-cell-associated markers. By conducting a systematic review of the literature, we have identified important gaps that impair our understanding of the intergenerational effects of diet, such as a paucity of experimental studies involving increased protein and decreased energy, and a lack of studies directed at the whole-organism consequences of these processes, such as immune resilience to infection. The results of our analyses inform our understanding of the effects of diet on physiological state across diverse biological fields, including biomedical sciences, maintenance of agricultural breed stock and conservation breeding programs, among others. PMID- 29178239 TI - Communities mobilizing for change on alcohol (CMCA): secondary analyses of a randomized controlled trial showing effects of community organizing on alcohol acquisition by youth in the Cherokee nation. AB - AIMS: We evaluated the effects of a community organizing intervention, Communities Mobilizing for Change on Alcohol (CMCA), on the propensity of retail alcohol outlets to sell alcohol to young buyers without age identification and on alcohol acquisition behaviors of underage youth. DESIGN: Random assignment of community to treatment (n = 3) or control (n = 2). Student surveys were conducted four times per year for 3 years; the cohort was in 9th and 10th grades in the 2012-13 academic year. Alcohol purchase attempts were conducted every 4 weeks at alcohol retailers in each community (31 repeated waves). SETTING: The Cherokee Nation, located in northeastern Oklahoma, USA. PARTICIPANTS: A total of 1399 high school students (50% male; 45% American Indian) and 113 stores licensed to sell alcohol across five study communities. INTERVENTION: Local community organizers formed independent citizen action teams to advance policies, procedures and practices of local institutions in ways to reduce youth access to alcohol and foster community norms opposed to teen drinking. MEASUREMENTS: Perceptions regarding police enforcement and perceived difficulty of and self-reported actual acquisition of alcohol from parents, adults, peers and stores. FINDINGS: Alcohol purchases by young-appearing buyers declined significantly, an 18 [95% confidence interval (CI) = 3, 33] percentage-point reduction over the intervention period. Student survey results show statistically significant differences in the trajectory of perceived police enforcement, increasing 7 (4, 10) percentage points, alcohol acquisition from parents, decreasing 4 (0.1, 8) percentage points, acquisition from 21+ adults, decreasing 6 (0.04, 11) percentage points, from < 21 peers decreasing 8 (3, 13) percentage points and acquisition from stores decreasing 5 (1, 9) percentage points. CONCLUSIONS: A community organizing intervention, Communities Mobilizing for Change on Alcohol (CMCA), is effective in reducing the availability of alcohol to underage youth in the United states. Furthermore, results indicate that the previously reported significant effects of CMCA on teen drinking operate, at least in part, through effects on alcohol access. PMID- 29178240 TI - Post-Operative Localization of Deep Brain Stimulation Electrodes in the Subthalamus Using Transcranial Sonography. AB - OBJECTIVES: The correct positioning of deep brain stimulation electrodes determines the success of surgery. In this study, we attempt to validate transcranial sonography (TCS) as a method for early postoperative confirmation of electrode location in the subthalamic nucleus (STN). MATERIALS AND METHODS: Nineteen patients diagnosed with Parkinson's disease were enrolled in the study. Postoperative TCS was applied to measure the distance between the implanted electrodes and the third ventricle in the axial plane. Whether the electrodes were positioned within or outside the substantia nigra (SN) was evaluated through measurements in the coronal plane. The obtained metrics through TCS were compared with those from postoperative computed tomography (CT) and magnetic resonance imaging (MRI). RESULTS: A statistically significant correlation between distances from electrode to third ventricle by TCS and CT/MRI (r = 0.75, p < 0.01) was observed. Distances from third ventricle to electrodes tips were different when sonographically they showed to be inside or outside the SN (p < 0.01). A cut-off value of 8.85mm in these distances was the most sensitive (100%) and specific (90.5%) to predict if electrodes were positioned inside the SN (CI 95% 0.81 10.30, p = 0.001). CONCLUSIONS: Transcranial sonography is a useful technique to reliably identify targeted positioning of deep brain stimulation electrodes in or out of the SN. PMID- 29178241 TI - Rare FMR1 gene mutations causing fragile X syndrome: A review. AB - Fragile X syndrome (FXS) is the most common inherited form of intellectual disability, typically due to CGG-repeat expansions in the FMR1 gene leading to lack of expression. We identified a rare FMR1 gene mutation (c.413G>A), previously reported in a single patient and reviewed the literature for other rare FMR1 mutations. Our patient at 10 years of age presented with the classical findings of FXS including intellectual disability, autism, craniofacial findings, hyperextensibility, fleshy hands, flat feet, unsteady gait, and seizures but without the typical CGG-repeat expansion. He had more features of FXS than the previously reported patient with the same mutation. Twenty individuals reported previously with rare missense or nonsense mutations or other coding disturbances of the FMR1 gene ranged in age from infancy to 50 years; most were verbal with limited speech, had autism and hyperactivity, and all had intellectual disability. Four of the 20 individuals had a mutation within exon 15, three within exon 5, and two within exon 2. The FMR1 missense mutation (c.413G>A) is the same as in a previously reported male where it was shown that there was preservation of the post-synaptic function of the fragile X mental retardation protein (FMRP), the encoded protein of the FMR1 gene was preserved. Both patients with this missense mutation had physical, cognitive, and behavioral features similarly seen in FXS. PMID- 29178242 TI - Deceased organ donor screening for human immunodeficiency virus, hepatitis B virus and hepatitis C virus: Discordant serology and nucleic acid testing results. AB - BACKGROUND: Before the 2014 policy change pertaining to infectious disease screening, many organ procurement organizations (OPOs) were supplementing serologic screening of deceased organ donors with nucleic acid testing (NAT) for human immunodeficiency virus (HIV-1), hepatitis B virus (HBV), and hepatitis C virus (HCV). The number of seronegative, NAT-positive donors has not been directly measured. METHODS: HIV, HBV, and HCV screening results of 11 229 donor referrals evaluated from 2010 to 2013 were obtained from 3 OPO-affiliated laboratories, capturing 35% of all donors in the United States. Laboratories used either polymerase chain reaction assay or transcription-mediated amplification assay to test 9643 deceased donors by NAT. RESULTS: The NAT results were positive in 21 (0.2%), 1 (0.02%), and 11 (0.1%) donors who were seronegative for HIV, HBV, and HCV, respectively. All discordant HIV-1 results were from one laboratory using a polymrease chain reaction assay. Thirteen of the reactive HIV NAT results in seronegative referrals were repeated and were non-reproducibly positive (NRP). Ten (0.1%), 452 (7.8%), and 197 (2.2%) of HIV-, HBV-, and HCV-seropositive donors, respectively, were negative by NAT. CONCLUSIONS: This study highlights the importance of robust quality assurance to minimize NRP NAT results. NAT may allow for increased utilization of organs from HBV- and HCV-seropositive, NAT negative donors. PMID- 29178243 TI - Probing the limits of predictability: data assimilation of chaotic dynamics in complex food webs. AB - The daunting complexity of ecosystems has led ecologists to use mathematical modelling to gain understanding of ecological relationships, processes and dynamics. In pursuit of mathematical tractability, these models use simplified descriptions of key patterns, processes and relationships observed in nature. In contrast, ecological data are often complex, scale-dependent, space-time correlated, and governed by nonlinear relations between organisms and their environment. This disparity in complexity between ecosystem models and data has created a large gap in ecology between model and data-driven approaches. Here, we explore data assimilation (DA) with the Ensemble Kalman filter to fuse a two predator-two-prey model with abundance data from a 2600+ day experiment of a plankton community. We analyse how frequently we must assimilate measured abundances to predict accurately population dynamics, and benchmark our population model's forecast horizon against a simple null model. Results demonstrate that DA enhances the predictability and forecast horizon of complex community dynamics. PMID- 29178244 TI - Status of tuberculosis-related stigma and associated factors: a cross-sectional study in central China. AB - OBJECTIVES: Tuberculosis (TB) poses a significant challenge to public health worldwide. Stigma is a major obstacle to TB control by leading to delay in diagnosis and treatment non-adherence. This study aimed to evaluate the status of TB-related stigma and its associated factors among TB patients in China. METHODS: Cross-sectional survey. Thus, 1342 TB patients were recruited from TB dispensaries in three counties in Hubei Province using a multistage sampling method and surveyed using a structured anonymous questionnaire including validated scales to measure TB-related stigma. A generalised linear regression model was used to identify the factors associated with TB-related stigma. RESULTS: The average score on the TB-related Stigma Scale was 9.33 (SD = 4.25). Generalised linear regression analysis revealed that knowledge about TB (beta = 0.18, P = 0.0025), family function (beta = -0.29, P < 0.0001) and doctor-patient communication (beta = -0.32, P = 0.0005) were negatively associated with TB related stigma. CONCLUSIONS: TB-related stigma was high among TB patients in China. Interventions concentrating on reducing TB patients' stigma in China should focus on improving patients' family function and patients' knowledge about TB. PMID- 29178245 TI - Temperature-programmed multicapillary gas chromatograph microcolumn for the analysis of odorous sulfur pollutants. AB - We report the fabrication and performance of a silicon-on-glass micro gas chromatography eight-capillary column based on microelectromechanical systems technology that is 50 cm long, 30 MUm wide, and 300 MUm deep. According to the theory of a gas chromatography column, an even gas flow among different capillaries play a vital role in the peak broadening. Thus, a flow splitter structure is designed by the finite element method through the comparison of the velocity distributions of the eight-capillary columns with and without splitter as well as an open tubular column. The simulation results reveal that eight capillary column with flow splitters can receive more uniform flow velocity in different capillaries, hence decreases the peak broadening and in turn increases the separation efficiency. The separation experiment results show that the separation efficiency of about 22 000 plates/m is achieved with the chip column temperature programmed for analysis of odorous sulfur pollutants. This figure is nearly two times higher than that of the commercial capillary column coated the similar stationary phase. And the separation time of all the components in the microcolumn is less than 3.8 min, which is faster than the commercial capillary column. PMID- 29178246 TI - Effects of the antagomiRs 15b and 200b on the altered healing pattern of diabetic mice. AB - BACKGROUND AND PURPOSE: Diabetic patients with non-healing ulcers have a reduced expression of VEGF. Genetically diabetic mice have an altered expression pattern of VEGF and its receptor, VEGF receptor 2 (VEGFR-2). In diabetic wounds, the microRNAs, miR15b and miR200b, which respectively inhibit VEGF and VEGF-R2 mRNAs, are up-regulated, further affecting the impaired angiogenesis. We investigated whether anti-miRs directed toward miR15b and miR200b could improve wound repair in genetically diabetic mice. EXPERIMENTAL APPROACH: Skin wounds were produced on the backs of female diabetic mice. The anti-miRs (antimiR15b, antimiR200b or antimiR15b/200b) at 10 mg.kg-1 , or vehicle were applied to the wound edge. Mice were killed on days 7, 14 and at time of complete wound closure. Levels of mRNA and protein of angiogenic mediators and their receptors were measured with RT qPCR and Western blotting. Wounds were examined by histological and immunochemical methods. KEY RESULTS: mRNA expression of VEGF, VEGFR-2, angiopoietin-1 and its receptor TEK were evaluated after 7 and 14 days. Protein levels of VEGF and transglutaminase II were measured at day 7, while VEGFR-2 and Angiopoietin-1 were measured at day 14. Histological features and the time to achieve a complete wound closure were also examined. Treatment with the anti-miRs improved the analysed parameters and the co-treatment resulted the most effective. CONCLUSION AND IMPLICATIONS: The results suggest that the inhibition of miR15b and miR200b may have a potential application in diabetes-related wound disorders. PMID- 29178247 TI - Isavuconazole shortens the QTc interval. AB - Isavuconazole is a novel antifungal drug approved for the treatment of adults with invasive aspergillosis and mucormycosis. While azoles as a class effect are known to prolong QTc interval, clinical trials have shown that isavuconazole administration may cause shortening in a dose-related manner. Here, we assessed the effects of isavuconazole on the length of QTc interval. The objective of the study was to describe changes in the QTc interval induced by isavuconazole treatment. A total of 26 adult patients from 7 hospitals were included. Patients received isavuconazole for the treatment of invasive fungal infection and, in 1 case, for prophylaxis due to QTc prolongation under fluconazole. Twelve-channel electrocardiograms (ECGs) were performed before and during treatment. Out of 26 patients, 24 showed shortening of QTc interval. In patients with QTc shortening, QTc during isavuconazole treatment showed a mean decrease of 7.4 +/- 5.8% (36.5 +/- 38.8 ms, range 7-202; P = .004), compared to pre-isavuconazole ECG. One patient with available long-term follow-up showed further decrease in QTc on days 55 and 110. Apart from 1 case report, these are the first data outside controlled clinical trials showing QTc shortening. Knowledge about cardiac effects of isavuconazole will serve to better manage the use of concomitant medications. PMID- 29178248 TI - No indication of increased infection rates using low-dose alemtuzumab instead of anti-thymocyte globulin as graft-versus-host disease prophylaxis before allogeneic stem cell transplantation. AB - BACKGROUND: Alemtuzumab as part of the conditioning protocol is effective in reducing graft-versus-host disease (GvHD), but may be associated with increased infection rates, especially when using high doses (ie, 100 mg). METHODS: We performed a retrospective, single-center, case-control study analyzing the rates of neutropenic fever, cytomegalovirus (CMV) reactivation, Epstein-Barr virus (EBV) reactivation, clinical manifest toxoplasmosis, and clinical manifest human herpesvirus-6 (HHV6) infection using low-dose alemtuzumab in comparison with anti thymocyte globulin (ATG) as GvHD prophylaxis before allogeneic stem cell transplantation. Forty-four patients transplanted from unrelated donors between 2001 and 2012 were matched by age, diagnosis, and conditioning regimen and treated either with alemtuzumab 10 mg at day -2 (respectively, 20 mg in case of mismatch transplantation) or ATG. ATG Fresenius (10 mg/kg for 3 days) or Thymoglobulin (2 mg/kg for 3 days) were used. RESULTS: Rates of CMV reactivation, EBV reactivation, and clinical manifest HHV6 infection or toxoplasmosis did not differ significantly between both groups until 2 years after transplantation. No case of post-transplant lymphoproliferative disorder was observed. Also, rates of neutropenic fever during inpatient treatment after transplantation did not differ significantly in both groups. CONCLUSION: We saw no indication of increased infections rates when using low-dose alemtuzumab as GvHD prophylaxis before allogeneic stem cell transplantation in this retrospective analysis. PMID- 29178249 TI - Validation of automated screening for referable diabetic retinopathy with the IDx DR device in the Hoorn Diabetes Care System. AB - PURPOSE: To increase the efficiency of retinal image grading, algorithms for automated grading have been developed, such as the IDx-DR 2.0 device. We aimed to determine the ability of this device, incorporated in clinical work flow, to detect retinopathy in persons with type 2 diabetes. METHODS: Retinal images of persons treated by the Hoorn Diabetes Care System (DCS) were graded by the IDx-DR device and independently by three retinal specialists using the International Clinical Diabetic Retinopathy severity scale (ICDR) and EURODIAB criteria. Agreement between specialists was calculated. Results of the IDx-DR device and experts were compared using sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), distinguishing between referable diabetic retinopathy (RDR) and vision-threatening retinopathy (VTDR). Area under the receiver operating characteristic curve (AUC) was calculated. RESULTS: Of the included 1415 persons, 898 (63.5%) had images of sufficient quality according to the experts and the IDx-DR device. Referable diabetic retinopathy (RDR) was diagnosed in 22 persons (2.4%) using EURODIAB and 73 persons (8.1%) using ICDR classification. Specific intergrader agreement ranged from 40% to 61%. Sensitivity, specificity, PPV and NPV of IDx-DR to detect RDR were 91% (95% CI: 0.69-0.98), 84% (95% CI: 0.81-0.86), 12% (95% CI: 0.08-0.18) and 100% (95% CI: 0.99-1.00; EURODIAB) and 68% (95% CI: 0.56-0.79), 86% (95% CI: 0.84-0.88), 30% (95% CI: 0.24-0.38) and 97% (95% CI: 0.95-0.98; ICDR). The AUC was 0.94 (95% CI: 0.88-1.00; EURODIAB) and 0.87 (95% CI: 0.83-0.92; ICDR). For detection of VTDR, sensitivity was lower and specificity was higher compared to RDR. AUC's were comparable. CONCLUSION: Automated grading using the IDx-DR device for RDR detection is a valid method and can be used in primary care, decreasing the demand on ophthalmologists.

A depression of coronary flow reserve is associated with a lower myocardial capillary density in biopsies. We hypothesized that changes in cardiac microcirculation might also be reflected by a systemic reduction in capillaries and visualized by sublingual videomicroscopy. The aim was to study in vivo capillary density and glycocalyx dimensions in patients with CHF vs healthy controls. METHODS: Fifty patients with ischaemic and nonischaemic CHF and standard treatment were compared to 35 healthy age-matched subjects in a prospective cross-sectional study. Sublingual microcirculation was visualized using a sidestream darkfield videomicroscope. Functional and perfused total capillary densities were compared between patients and controls. A reduced glycocalyx thickness was measured by an increased perfused boundary region (PBR). RESULTS: Median functional and total perfused capillary densities were 30% and 45% lower in patients with CHF (both P < .001). Intake of oral vitamin K antagonists was associated with significantly lower capillary densities (P < .05), but not independent of NT-proBNP. Dimensions of the glycocalyx were marginally lower in CHF patients than in healthy controls (<7% difference). However, PBR correlated significantly with inflammation markers (fibrinogen: r = .58; C-reactive protein: r = .42), platelet counts (r = .36) and inversely with measures of liver/renal function such as bilirubin (r = -.38) or estimated glomerular filtration rate (r = -.34) in CHF patients. CONCLUSION: CHF patients have got a markedly lower functional and total perfused capillary density in sublingual microvasculature when compared to controls, indicating a systemic decrease in microcirculation. PMID- 29178251 TI - Seizure and cognitive outcomes after resection of glioneuronal tumors in children. AB - OBJECTIVE: Glioneuronal tumors (GNTs) are well-recognized causes of chronic drug resistant focal epilepsy in children. Our practice involves an initial period of radiological surveillance and antiepileptic medications, with surgery being reserved for those with radiological progression or refractory seizures. We planned to analyze the group of patients with low-grade GNTs, aiming to identify factors affecting seizure and cognitive outcomes. METHODS: We retrospectively reviewed the medical records of 150 children presenting to Great Ormond Street Hospital with seizures secondary to GNTs. Analysis of clinical, neuroimaging, neuropsychological, and surgical factors was performed to determine predictors of outcome. Seizure outcome at final follow-up was classified as either seizure-free (group A) or not seizure-free (group B) for patients with at least 12-months follow-up postsurgery. Full-scale intelligence quotient (FSIQ) was used as a measure of cognitive outcome. RESULTS: Eighty-six males and 64 females were identified. Median presurgical FSIQ was 81. One hundred twenty-one patients (80.5%) underwent surgery. Median follow-up after surgery was 2 years, with 92 patients (76%) having at least 12 months of follow-up after surgery. Seventy-four patients (80%) were seizure-free, and 18 (20%) continued to have seizures. Radiologically demonstrated complete tumor resection was associated with higher rates of seizure freedom (P = .026). Higher presurgical FSIQ was related to shorter epilepsy duration until surgery (P = .012) and to older age at seizure onset (P = .043). SIGNIFICANCE: A high proportion of children who present with epilepsy and GNTs go on to have surgical tumor resection with excellent postoperative seizure control. Complete resection is associated with a higher chance of seizure freedom. Higher presurgical cognitive functioning is associated with shorter duration of epilepsy prior to surgery and with older age at seizure onset. Given the high rate of eventual surgery, early surgical intervention should be considered in children with continuing seizures associated with GNTs. PMID- 29178252 TI - The cross-sectional associations between objectively measured sedentary time and cardiometabolic health markers in adults - a systematic review with meta-analysis component. AB - Sedentary time is viewed as an independent risk factor for adverse cardiometabolic health (CMH). No systematic review and meta-analysis on the cross sectional associations between objectively measured sedentary time and CMH markers has been conducted. PubMed, Scopus and Web of Science Core Collection were searched for papers that examined the cross-sectional association between objectively measured sedentary time and CMH markers in adults. Forty-six papers met the inclusion criteria. The included papers had a combined sample size of 70,576 and an age range of 18-87 years. To examine the effect of increased levels of sedentary time on CMH markers, data on effect sizes and moderators were extracted, where possible. By pooling the unadjusted data from the included papers, increased sedentary time was shown to have a significant detrimental association with fasting glucose (Delta = 0.12, 95% confidence interval [CI]: 0.02, 0.23), fasting insulin (Delta = 0.19, 95% CI: 0.06, 0.32), triglycerides (Delta = 0.25, 95% CI: 0.14, 0.37), high-density lipoprotein cholesterol (Delta = -0.20, 95% CI: -0.28, -0.13) and waist circumference (Delta = 0.25, 95% CI: 0.15, 0.35). How sedentary time was quantified and the device used to measure sedentary time significantly influence the size of the effect reported. Future interventions focused on both decreasing sedentary time and increasing physical activity may be the most effective strategy to improve CMH. PMID- 29178253 TI - Kefir Peptides Prevent Hyperlipidemia and Obesity in High-Fat-Diet-Induced Obese Rats via Lipid Metabolism Modulation. AB - SCOPE: Obesity has reached epidemic proportions worldwide. Obesity is a complex metabolic disorder that is linked to numerous serious health complications with high morbidity. The present study evaluated the effects of kefir peptides on high fat diet (HFD)-induced obesity in rats. METHODS AND RESULTS: Kefir peptides markedly improved obesity, including body weight gain, inflammatory reactions and the formation of adipose tissue fat deposits around the epididymis and kidney, and adipocyte size. Treating high fat diet (HFD)-induced obese rats with kefir peptides significantly reduced the fatty acid synthase protein and increased the p-acetyl-CoA carboxylase protein to block lipogenesis in the livers. Kefir peptides also increased fatty acid oxidation by increasing the protein expressions of phosphorylated AMP-activated protein kinase, peroxisome proliferator-activated receptor-alpha, and hepatic carnitine palmitoyltransferase 1 in the livers. In addition, administration of kefir peptides significantly decreased the inflammatory response (TNF-alpha, IL-1beta, and TGF-beta) to modulate oxidative damage. CONCLUSION: These results demonstrate that kefir peptides treatment improves obesity via inhibition of lipogenesis, modulation of oxidative damage, and stimulation of lipid oxidation. Therefore, kefir peptides may act as an anti-obesity agent to prevent body fat accumulation and obesity related metabolic diseases.

AB - While thioesters are common intermediates in biochemical processes, they are much less appreciated in organic synthesis, also compared to other carboxylic acid derivatives. However, their chemistry and reactivity is intriguing and diversified, reaching much further than the acyl substitution and aldol chemistry. Herein, we focus on metal-catalyzed reactions for the synthesis of thioesters as well as their transformations. Reactions such as thiocarbonylation, cross-coupling, decarbonylation, allylic substitution or dual photoredox/metal catalysis are discussed. On one hand, new atom economic methods allow for convenient synthesis of thioesters from well available starting materials. On the other hand, various synthetically important compounds can by synthesized due to the multifaceted reactivity of thioesters that we aimed to depict. PMID- 29178256 TI - Tuboperitoneal anomalies among infertile women in Nigeria as seen on laparoscopy. AB - OBJECTIVE: To study the prevalence and pattern of tuboperitoneal pathologies among infertile women in Nigeria, using laparoscopy. METHODS: A prospective study was undertaken of infertile women who underwent diagnostic laparoscopy in two fertility clinics in Nigeria between November 2015 and April 2017. The rates of identified tuboperitoneal diseases were examined. RESULTS: The age of the 230 women ranged from 21 to 46 years, and most women had a parity group of 0-1 (87.8%; n=202). Secondary infertility accounted for 124 (53.9%) cases, and the mean duration of infertility was 4.6 +/- 2.7 years. Tuboperitoneal pathologies were seen in 171 (74.4%) women and mainly comprised tubal occlusion (56.5%; n=130), hydrosalpinx (41.7%; n=96), pelvic adhesions (39.6%, n=91), and endometriosis (8.8%; n=19). Bilateral tubal occlusion was seen in 46 (20.0%) women, whereas proximal tubal occlusion accounted for 73 (56.2%) of all cases of tubal occlusion. CONCLUSION: There was a high rate of tuboperitoneal abnormalities in the studied population, which mainly comprised tubal occlusion, hydrosalpinx, pelvic adhesions, and endometriosis. The introduction of laparoscopy is recommended in the initial evaluation of all women with infertility in Nigeria. PMID- 29178257 TI - Gender-Specific Association Between ABCC2 -24C>T SNP and Reduction in Triglycerides in Chilean Patients Treated With Atorvastatin. AB - Statins are the first-line therapy prescribed to lower plasma cholesterol levels. Although being safe and showing several beneficial cholesterol-independent pleiotropic effects, a significant variability regarding statin's therapeutic goals has been abundantly documented, but less understood. We aimed to investigate the influence of the ABCC2 -24C>T single nucleotide polymorphism on Chilean hypercholesterolaemic individuals treated for 4 weeks with 10 mg/day atorvastatin. A total of 127 individuals medicated with atorvastatin 10 mg/day/4 weeks were included. Lipid profiles were determined before and after drug administration by conventional assays. Genotyping of the ABCC2 rs717620 SNP ( 24C>T) was performed with TaqMan(r) Drug Metabolism Genotyping Assays. As expected, atorvastatin reduced TC, LDL-C and TG concentrations (p < 0.05). Also, HDL-C levels were increased (p < 0.05). Minor allele frequency for the rs717620 was 0.232. Overall, atorvastatin response was not associated with the ABCC2 rs717620 SNP (p > 0.05). Nonetheless, in male individuals carrying the -24T allele, we observed an attenuated reduction in both TG values and the TG/HDL-C ratio after 10 mg/day atorvastatin. This study indicates that TG levels and the TG/HDL-C ratio are affected by the rs717620 SNP in Chilean males but not female individuals after atorvastatin treatment. PMID- 29178258 TI - Feasibility analysis of early temporal kinetics as a surrogate marker for breast tumor type, grade, and aggressiveness. AB - BACKGROUND: Screening breast MRI has been shown to preferentially detect high grade ductal carcinoma in situ (DCIS) and invasive carcinoma, likely due to increased angiogenesis resulting in early initial uptake of contrast. As interest grows in abbreviated screening breast MRI (AB-MRI), markers of early contrast washin that can predict tumor grade and potential aggressiveness are of clinical interest. PURPOSE: To evaluate the feasibility of using the initial enhancement ratio (IER) as a surrogate marker for tumor grade, hormone receptor status, and prognostic markers, as an initial step to being incorporated into AB-MRI. STUDY TYPE: Retrospective. SUBJECTS: In all, 162 women (mean 55.0 years, range 32.8 87.7 years) with 187 malignancies imaged January 2012-November 2015. FIELD STRENGTH/SEQUENCE: Images were acquired at 3.0T with a T1 -weighted gradient echo fat-suppressed-volume interpolated breath-hold sequence. ASSESSMENT: Subjects underwent dynamic contrast-enhanced breast MRI with a 7-channel breast coil. IER (% signal increase over baseline at the first postcontrast acquisition) was assessed and correlated with background parenchymal enhancement, washout curves, stage, and final pathology. STATISTICAL TESTS: Chi-square test, Spearman rank correlation, Mann-Whitney U-tests, Bland-Altman analysis, and receiver operating characteristic curve analysis. RESULTS: IER was higher for invasive cancer than for DCIS (R1/R2, P < 0.001). IER increased with tumor grade (R1: r = 0.56, P < 0.001, R2: r = 0.50, P < 0.001), as ki-67 increased (R1: r = 0.35, P < 0.001; R2 r = 0.35, P < 0.001), and for node-positive disease (R1/R2, P = 0.001). IER was higher for human epidermal growth factor receptor two-positive and triple negative cancers than for estrogen receptor-positive / progesterone receptor positive tumors (R1 P < 0.001-0.002; R2 P = 0.0.001-0.011). IER had higher sensitivity (80.6% vs. 75.5%) and specificity (55.8% vs. 48.1%) than washout curves for positive nodes, higher specificity (48.1% vs. 36.5%) and positive predictive value (70.2% vs. 66.7%) for high ki-67, and excellent interobserver agreement (intraclass correlation coefficient = 0.82). DATA CONCLUSION: IER, a measurement of early contrast washin, is associated with higher-grade malignancies and tumor aggressiveness and might be potentially incorporated into an AB-MRI protocol.

PMID- 29178259 TI - The Effect of Different l-Carnitine Administration Routes on the Development of Atherosclerosis in ApoE Knockout Mice. AB - SCOPE: l-Carnitine (LC) is abundant in red meat and is widely added to health supplements and food. This study focuses on the adverse effects of oral supplementation of 1.3% LC in ApoE-/- mice and whether the parenteral administration of LC (subcutaneously, sub) has any impact on the development of atherosclerosis. METHODS AND RESULTS: Mice are randomly divided into three groups (n = 15). All mice are fed a high-fat diet (HFD). The number of Ly6Chi monocytes; degree of atherosclerosis; plasma LC, gamma-butyrobetaine (gammaBB), and trimethylamine-N-oxide (TMAO) levels; and microbial community composition are analyzed. Compared with the HFD and HFD +/- LC (sub) groups, the number of Ly6Chi monocytes, atherosclerotic plaque area, and plasma gammaBB and TMAO levels are increased in the HFD +/- LC (oral) group (p < 0.001). Plasma LC levels in the HFD +/- LC (sub) group are higher than those in other groups. The levels of gammaBB, TMAO, and Ly6Chi monocytes are positively correlated with atherosclerotic plaque area (p < 0.01), and TMAO is positively correlated with Bacteroidetes and negatively correlated with Firmicutes at the phylum level. CONCLUSION: In contrast with oral LC administration, subcutaneous LC administration, which bypasses its conversion to TMAO in the liver, does not have a detrimental effect on the development of atherosclerosis in male ApoE-/- mice. Taking LC parenterally may be preferable among patients who require LC supplementation. PMID- 29178260 TI - Origin of clear cell carcinoma: nature or nurture? AB - A rare but serious complication of endometriosis is the development of carcinoma, and clear cell and endometrioid carcinomas of the ovary are the two most common malignancies which arise from endometriosis. They are distinct diseases, characterized by unique morphologies, immunohistochemical profiles, and responses to treatment. However, both arise in endometriosis and can share common mutations. The overlapping mutational profiles of clear cell and endometrioid carcinomas suggest that their varied histologies may be due to a different cell of origin which gives rise to each type of cancer. Cochrane and colleagues address this question in a recent article in this journal. They show that a marker of ovarian clear cell carcinoma, cystathionine gamma lyase, is expressed in ciliated cells. Similarly, they show that markers of secretory cells (estrogen receptor and methylenetetrahydrofolate dehydrogenase 1) are expressed in ovarian endometrioid carcinoma. Taken together, they suggest that endometrioid and clear cell carcinomas arise from cells related to secretory and ciliated cells, respectively. We discuss Cochrane et al's work in the context of other efforts to determine the cell of origin of gynecological malignancies, with an emphasis on recent developments and challenges unique to the area. These limitations complicate our interpretation of tumor differentiation; does it reflect nature imposed by a specific cell of origin or nurture, by either mutation(s) or environment?

PMID- 29178262 TI - Selective detection of alpha4beta1 integrin (VLA-4)-expressing cells using peptide-functionalized nanostructured materials mimicking endothelial surfaces adjacent to inflammatory sites. AB - Persistent accumulation of immune cells mediated by alpha4beta1 integrin (VLA-4) is a hallmark of the inflammatory diseases and of chronic inflammation observed in the affected tissues of autoimmune diseases. Aiming at exploring new methods for monitoring the course of the inflammatory processes, we designed the first peptide-functionalized nanostructured devices capable to mimic the high-density multivalency binding between the alpha4beta1 integrin-expressing cells and the ligands overexpressed on the endothelial surfaces, in the proximity of the sites of inflammation. Specifically, we describe the first examples of monolayers constituted by dye-loaded zeolite L crystals, coated with alpha4beta1 integrin peptide ligands, and we analyze the adhesion of model Jurkat cells in comparison to non-alpha4beta1 integrin-expressing cells. In particular, the peptidomimetic diphenylurea-Leu-Asp-Val-diamine allows significant and selective detection of alpha4beta1 integrin-expressing Jurkat cells, after very rapid incubation time, supporting the possible implementation in a diagnostic device capable to detect the desired cells from biological fluids, obtainable from patients in a noninvasive way.

AB - BACKGROUND: Upper gastrointestinal symptoms in children are common and motility disorders are considered in the differential diagnosis. High resolution esophageal manometry (HRM) has revolutionized the study of esophageal physiology, and the addition of impedance has provided new insights into esophageal function. Antroduodenal motility has provided insight into gastric and small bowel function. PURPOSE: This review highlights some of the recent advances in pediatric esophageal and antroduodenal motility testing including indications, preparation, performance, and interpretation of the tests. This update is the second part of a two part series on manometry studies in children (first part was on anorectal and colonic manometry [Neurogastroenterol Motil. 2016;29:e12944]), and has been endorsed by the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and the American Neurogastroenterology and Motility Society (ANMS). PMID- 29178263 TI - Characterizing the free volume of ultrahigh molecular weight polyethylene to predict diffusion coefficients in orthopedic liners. AB - Liners used in orthopedic devices are often made from ultrahigh molecular weight polyethylene (UHMWPE). A general predictive capability for transport coefficients of small molecules in UHMWPE does not exist, making it difficult to assess properties associated with leaching or uptake of small molecules. To address this gap, we describe here how a form of the Vrentas-Duda free volume model can be used to predict upper-bound diffusion coefficients (D) of arbitrary molecules within UHMWPE on the basis of their size and shape. Within this framework, the free-volume microstructure of UHMWPE is defined by analysis of a curated set of model diffusants. We determined an upper limit on D for vitamin E, a common antioxidant added to UHMWPE, to be 7.1 * 10-12 cm2 s-1 . This means that a liner that contains 0.1 wt % or less Vitamin E and has <120 cm2 patient contacting surface area would elute <100 ug/day of vitamin E. Additionally, the model predicts that squalene and cholesterol-two pro-oxidizing biological compounds-do not penetrate over 820 um into UHMWPE liners over the course of 5 years because their D is <=7.1 * 10-12 cm2 s-1 .

PMID- 29178264 TI - Assessing the validity of self-reported history of rash caused by metal or jewellery. AB - BACKGROUND: The use of metal-containing bio-devices is becoming increasingly common. Self-reported history of dermatitis with metal exposure is not established as being predictive for metal allergy. OBJECTIVES: To assess the validity of two screening questions addressing metal allergy. METHODS: At Massachusetts General Hospital Contact Dermatitis Clinic, 2132 consecutive patients were asked either 'Do you get rashes when jewellery touches your skin' (Q1; N = 1816) or 'Do you get rashes when metal touches your skin?' (Q2; N = 316) before being patch tested. RESULTS: Testing showed that 20% of subjects had positive reactions to nickel, 7.4% had positive reactions to cobalt, and 5.8% had positive reactions to chromium. Q1 was 40% sensitive (95%CI: 35-45%). The positive predictive value (PPV) was 51%, and the negative predictive value (NPV) was 82%. Q2 was 77% sensitive (95%CI: 68-84%). The PPV was 71%, and the NPV was 84%. Q2 was 37% more sensitive than Q1 (p < 0.0001), with a higher relative risk (RR) (4.75, p < 0.001) than Q1 (RR = 3.01, p < 0.001). CONCLUSIONS: Patient reported metal allergy, although not perfect, is a reasonable method for metal allergy screening to help identify those needing further objective evaluation by patch testing. PMID- 29178265 TI - Surgical interventions for vertical strabismus in superior oblique palsy. AB - BACKGROUND: Superior oblique palsy is a common cause of vertical strabismus in adults and children. Patients may be symptomatic from binocular vertical diplopia or compensatory head tilt required to maintain single vision. Most patients who are symptomatic elect to undergo strabismus surgery, but the optimal surgical treatment for vertical strabismus in people with superior oblique palsy is unknown. OBJECTIVES: To assess the relative effects of surgical treatments compared with another surgical intervention, non-surgical intervention, or observation for vertical strabismus in people with superior oblique palsy. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 12), MEDLINE Ovid (1946 to 13 December 2016), Embase Ovid (1947 to 13 December 2016), Latin American and Caribbean Health Sciences Literature Database (LILACS) (1982 to 13 December 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch); searched 13 December 2016, ClinicalTrials.gov (www.clinicaltrials.gov); searched 13 December 2016, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en); searched 13 December 2016. We did not use any date or language restrictions in the electronic searches for trials. SELECTION CRITERIA: We included randomized trials that compared at least one type of surgical intervention to another surgical or non surgical intervention or observation. DATA COLLECTION AND ANALYSIS: Two review authors independently completed eligibility screening, data abstraction, 'Risk of bias' assessment, and grading of the evidence. MAIN RESULTS: We identified two randomized trials comparing four different surgical treatments for this condition, two methods in each trial. The studies included a total of 45 children and adults. The surgical treatments were all procedures to weaken the ipsilateral inferior oblique muscle. One study compared inferior oblique myectomy to recession of 10 mm; the other study compared inferior oblique disinsertion to anterior transposition (2 mm anterior to the temporal border of the inferior rectus insertion).We judged both studies to be at unclear risk of bias due to incomplete reporting of methods and other methodological deficiencies.Neither study reported data on the primary outcome of this review, which was the proportion of participants with postoperative surgical success, defined as hypertropia less than 3 prism diopters (PD) in primary gaze. However, both studies reported the average reduction in hypertropia in primary gaze. One study found that at 12 months' postoperatively the average decrease in hypertropia was higher in participants who underwent inferior oblique myectomy than in those who underwent recession, however data were not available for statistical comparison. The other trial found that after at least six months of follow-up, the mean decrease in primary position hypertropia was lower in participants who underwent inferior oblique disinsertion than in those who underwent anterior transposition (mean difference (MD) -5.20 PD, 95% confidence interval (CI) -7.76 to -2.64; moderate-quality evidence).Both trials also reported the average postoperative reduction in vertical deviation in adduction. One study reported that the average reduction in hypertropia in adduction was greater in participants who underwent inferior oblique myectomy than in those who underwent recession, but data were not available for statistical comparison. The other study found a lower decrease in hypertropia in contralateral gaze in participants who underwent inferior oblique disinsertion than in those who underwent anterior transposition (MD -7.10 PD, 95% CI -13.85 to -0.35; moderate-quality evidence).Secondary outcomes with sufficient data for analysis included proportion of participants with preoperative head tilt that resolved postoperatively and proportion of participants who underwent a second surgery. These outcomes were assessed in the trial comparing inferior oblique anterior transposition to disinsertion; both outcomes favored anterior transposition (risk ratio 7.00, 95% CI 0.40 to 121.39 for both outcomes; very low-quality evidence). None of the participants who underwent inferior oblique anterior transposition or disinsertion developed postoperative hypotropia or reversal of the vertical deviation. All participants who underwent inferior oblique anterior transposition developed elevation deficiency, which the authors deemed to be clinically insignificant in all cases, whereas no participants who underwent inferior oblique disinsertion experienced this complication. Additionally, the trial comparing inferior oblique myectomy to recession reported that no participant in either group required another strabismus surgery during the postoperative period. AUTHORS' CONCLUSIONS: The two trials included in this review evaluated four inferior oblique weakening procedures for surgical treatment of superior oblique palsy. We found no trials comparing other types of surgical procedures for this disorder. Both studies had enrolled a small number of participants and provided low-quality evidence due to limitations in completeness and applicability. We therefore found no high-quality evidence to support recommendations for optimal surgical treatment of superior oblique palsy. Rigorously designed, conducted, and reported randomized trials are needed to identify the optimal surgical treatment for vertical strabismus in this disorder. PMID- 29178266 TI - Neurocognitive outcome in young adults born late-preterm. AB - AIM: This study examined whether late-preterm birth (34+0 to 36+6wks+d gestational age) was associated with neurocognitive deficit in young adulthood, and whether small for gestational age (SGA) birth amplified any adversity. METHOD: Participants derived from the prospective regional cohort study, the Arvo Ylppo Longitudinal Study (n=786; 398 females, 388 males) (mean age 25y 4mo, SD 8mo), born 1985 to 1986 late-preterm (n=119; 21 SGA, <-2 SD) and at term (37+0 to 41+6wks+d; n=667; 28 SGA) underwent tests of intelligence, executive functioning, attention, and memory, and reported their education. RESULTS: Those born late preterm scored -3.71 (95% confidence interval [CI] -6.71 to -0.72) and -3.11 (95% CI -6.01 to -0.22) points lower on Full-scale and Verbal IQ than peers born at term. Compared with those born at term and appropriate for gestational age (>=-2 to <2 SD) Full-scale, Verbal, and Performance IQ scores of those born late preterm and SGA were -9.45 to -11.84 points lower. After adjustments, differences were rendered non-significant, except that scores in Full-scale and Performance IQ remained lower among those born late-preterm and SGA. INTERPRETATION: Late preterm birth, per se, may not increase the risk of poorer neurocognitive functioning in adulthood. But the double burden of being born late-preterm and SGA seems to increase this risk. WHAT THIS PAPER ADDS: Late-preterm birth did not increase the risk of poorer neurocognitive functioning in adulthood. But the double burden of being born late-preterm and being small for gestational age did increase this risk. PMID- 29178267 TI - Tracing the origins of genotype VIIh Newcastle disease in southern Africa. AB - It is widely accepted that Newcastle disease is endemic in most African countries, but little attention has been afforded to establishing the sources and frequency of the introductions of exotic strains. Newcastle disease outbreaks have a high cost in Africa, particularly on rural livelihoods. Genotype VIIh emerged in South-East Asia and has since caused serious outbreaks in poultry in Malaysia, Indonesia, southern China, Vietnam and Cambodia. Genotype VIIh reached the African continent in 2011, with the first outbreaks reported in Mozambique. Here, we used a combination of phylogenetic evidence, molecular dating and epidemiological reports to trace the origins and spread of subgenotype VIIh Newcastle disease in southern Africa. We determined that the infection spread northwards through Mozambique, and then into the poultry of the north-eastern provinces of Zimbabwe. From Mozambique, it also reached neighbouring Malawi and Zambia. In Zimbabwe, the disease spread southward towards South Africa and Botswana, causing outbreaks in backyard chickens in early-to-mid 2013. In August 2013, the disease entered South Africa's large commercial industry, and the entire country was infected within a year, likely through fomites and the movements of cull chickens. Illegal poultry trading or infected waste from ships and not wild migratory birds was the likely source of the introduction to Mozambique in 2011. PMID- 29178268 TI - Selective extraction of morphine from biological fluids by magnetic molecularly imprinted polymers and determination using UHPLC with diode array detection. AB - The determination of morphine concentration in the blood and urine is necessary for patients and recruitment purposes. Herein, a magnetic molecularly imprinted polymer for selective and efficient extraction of morphine from biological samples was synthesized by using a core-shell method. Fe3 O4 nanoparticles were coated with SiO2 -NH2 . The molecularly imprinted polymer was coated on the Fe3 O4 /SiO2 -NH2 surface by the copolymerization of methacrylic acid and ethylene glycol dimethacrylate in the presence of morphine as the template molecule. The morphological and magnetic properties of the polymer were investigated. Field emission scanning electron microscopy indicated that the prepared magnetic polymer is almost uniform. The saturation magnetization values of Fe3 O4 nanoparticles, Fe3 O4 /SiO2 -NH2 , and the magnetic polymer were 48.41, 31.69, and 13.02 emu/g, respectively, indicating that all the particles are superparamagnetic. Kinetics of the adsorption of morphine on magnetic polymer were well described by second-order kinetic and adsorption processes and well fitted by the Langmuir adsorption isotherm, in which the maximum adsorption capacity was calculated as 28.40 mg/g. The recoveries from plasma and urine samples were in the range of 84.9-105.5 and 94.9-102.8%, respectively. By using the magnetic molecularly imprinted polymer, morphine can selectively, reliably, and in low concentration be determined in biological samples with high performance liquid chromatography and UV detection. PMID- 29178269 TI - Unmodern Synthesis: Developmental Hierarchies and the Origin of Phenotypes. AB - The question of whether the modern evolutionary synthesis requires an extension has recently become a topic of discussion, and a source of controversy. We suggest that this debate is, for the most part, not about the modern synthesis at all. Rather, it is about the extent to which genetic mechanisms can be regarded as the primary determinants of phenotypic characters. The modern synthesis has been associated with the idea that phenotypes are the result of gene products, while supporters of the extended synthesis have suggested that environmental factors, along with processes such as epigenetic inheritance, and niche construction play an important role in character formation. We argue that the methodology of the modern evolutionary synthesis has been enormously successful, but does not provide an accurate characterization of the origin of phenotypes. For its part, the extended synthesis has yet to be transformed into a testable theory, and accordingly, has yielded few results. We conclude by suggesting that the origin of phenotypes can only be understood by integrating findings from all levels of the organismal hierarchy. In most cases, parts and processes from a single level fail to accurately explain the presence of a given phenotypic trait. PMID- 29178270 TI - Asymmetric Synthesis of 2H-Azirines with a Tetrasubstituted Stereocenter by Enantioselective Ring Contraction of Isoxazoles. AB - Highly strained 2H-azirines with a tetrasubstituted stereocenter were synthesized by the enantioselective isomerization of isoxazoles with a chiral diene-rhodium catalyst system. The effect of ligands and the coordination behavior support the proposed catalytic cycle in which the coordination site is fixed in favor of efficient enantiodiscrimination by a bulky substituent of the ligand. In silico studies also support the existence of a rhodium-imido complex as a key intermediate for enantiodiscrimination.

AB - AIM: The purpose of the present study was to evaluate the relationship between the maxillary sinus floor and the upper posterior root tips in the Colombian population using cone-beam computed tomography. METHODS: A total of 1656 roots were analyzed (1104 molars and 552 premolars), classified as types I (outside the maxillary sinus) and II (inside the maxillary sinus). RESULTS: The results showed that the palatal root of the maxillary first molar was most frequently found inside the antrum. CONCLUSIONS: Understanding the relationship between the maxillary sinus floor and the upper posterior root tips is important to the clinician when performing conventional or surgical endodontic treatment and conventional surgery procedures in order to minimize or avoid the risk of damaging the maxillary sinus. PMID- 29178272 TI - Evaluation of modafinil as a perpetrator of metabolic drug-drug interactions using a model informed cocktail reaction phenotyping trial protocol. AB - AIM: To evaluate the capacity for modafinil to be a perpetrator of metabolic drug drug interactions by altering cytochrome P450 activity following a single dose and dosing to steady state. METHODS: A single centre, open label, single sequence cocktail drug interaction trial. On days 0, 2 and 8 participants were administered an oral drug cocktail comprising 100 mg caffeine, 30 mg dextromethorphan, 25 mg losartan, 1 mg midazolam and 20 mg enteric-coated omeprazole. Timed blood samples were collected prior to and for up to 6 h post cocktail dosing. Between days 2 and 8 participants orally self-administered 200 mg modafinil each morning. RESULTS: Following a single 200 mg dose of modafinil mean (+/- 95% CI) AUC ratios for caffeine, dextromethorphan, losartan, midazolam and omeprazole were 0.95 (+/- 0.08), 1.01 (+/- 0.35), 0.97 (+/- 0.10), 0.98 (+/- 0.10) and 1.36 (+/- 0.06), respectively. Following dosing of modafinil to steady state (200 mg for 7 days), AUC ratios for caffeine, dextromethorphan, losartan, midazolam and omeprazole were 0.90 (+/- 0.16), 0.79 (+/- 0.09), 0.98 (+/- 0.11), 0.66 (+/- 0.12) and 1.90 (+/- 0.53), respectively. CONCLUSIONS: These data support consideration of the risk of clinically relevant metabolic drug-drug interactions perpetrated by modafinil when this drug is co-administered with drugs that are primarily cleared by CYP2C19 (single modafinil dose or steady state modafinil dosing) or CYP3A4 (steady state modafinil dosing only) catalysed metabolic pathways.

AB - Laparoscopic colonic resections often require manipulation and surgical action in all abdominal quadrants. Port placement, a fundamental part of a successful procedure, often varies widely among surgeons and is currently dictated by individual experience and preference. This variability may be suboptimal for the operation at hand, can be confusing for trainees and many times provide inadequate working posture for the surgeons, resulting in discomfort due to muscular fatigue in the hands, arms, shoulders and cervical spine.

PMID- 29178274 TI - Lactate >=2 mmol/L plus qSOFA improves utility over qSOFA alone in emergency department patients presenting with suspected sepsis. AB - OBJECTIVE: The Sepsis-3 task force recommends the use of the quick Sequential Organ Failure Assessment (qSOFA) score to identify risk for adverse outcomes in patients presenting with suspected infection. Lactate has been shown to predict adverse outcomes in patients with suspected infection. The aim of the study is to investigate the utility of a post hoc lactate threshold (>=2 mmol/L) added qSOFA score (LqSOFA(2) score) to predict primary composite adverse outcomes (mortality and/or ICU stay >=72 h) in patients presenting to ED with suspected sepsis. METHODS: Retrospective cohort study was conducted on a merged dataset of suspected or proven sepsis patients presenting to ED across multiple sites in Australia and The Netherlands. Patients are identified as candidates for quality improvement initiatives or research studies at respective sites based on local screening procedures. Data-sharing was performed across sites of demographics, qSOFA, SOFA, lactate thresholds and outcome data for included patients. LqSOFA(2) scores were calculated by adding an extra point to qSOFA score in patients who met lactate thresholds of >=2 mmol/L. RESULTS: In a merged dataset of 12 555 patients where a full qSOFA score and outcome data were available, LqSOFA(2) >=2 identified more patients with an adverse outcome (sensitivity 65.5%, 95% confidence interval 62.6-68.4) than qSOFA >=2 (sensitivity 47.6%, 95% confidence interval 44.6- 50.6). The post hoc addition of lactate threshold identified higher proportion of patients at risk of adverse outcomes. CONCLUSIONS: The lactate >=2 mmol/L threshold-based LqSOFA(2) score performs better than qSOFA alone in identifying risk of adverse outcomes in ED patients with suspected sepsis.

Here, we describe a patient with a pulmonary artery sarcoma, which was only subtly visible and therefore not fully appreciated on initial transthoracic echocardiogram. Characterization of the tumor was aided by the use of multimodality imaging that included computed tomography, magnetic resonance imaging, and positron emission tomography. Familiarity with its appearance on multiple imaging modalities including echocardiography is important to ensure timely diagnosis, although the optimal treatment strategy is still unknown, and the prognosis remains poor. PMID- 29178280 TI - Warm-Up Effect in Panelist-Articulated-2-Alternative Forced Choice Test. AB - : Panelist performance in discrimination tests has been shown to increase when warm-up samples are provided prior to the actual test. Samples are used prior to the actual test for the attribute articulation process of a panelist-articulated 2-alternative forced choice (PA-2-AFC) procedure; however, it is yet unknown if the pretest articulation phase adds to the power of this testing method as with the warm-up. The goal of the study was to determine if a "warm-up" effect was displayed in the PA-2-AFC test resulting in greater power compared to the researcher-designated-2-AFC (RD-2-AFC) test. A RD-2-AFC test, with and without warm-up samples, and a PA-2-AFC test were performed by 61 panelists. A reduced calorie, citrus-flavored, and carbonated beverage was used in the tests. During RD-2-AFC testing, panelists were asked to identify which sample was more sour. For PA-2-AFC testing, panelists individually articulated the nature and direction of the difference between the 2 samples through a pretesting articulation procedure. The articulated difference was, then, used in standard 2-AFC test procedure. A warm-up effect was observed when comparing the standard RD-2-AFC with and without warm-up samples. The addition of warm up samples significantly increased the power of the test, in addition, the PA-2-AFC method had lower power than the RD-2-AFC method. The increase in power with the addition of warm-up samples for the RD-2-AFC procedure supports literature findings on the benefit of providing warm-up samples. No warm-up effect can be attributed to the PA-2-AFC method evidenced by the overall low power observed, which may be attributed to sample complexity. PRACTICAL APPLICATION: Selecting a specified discrimination testing method is advantageous and can reduce costs of sensory testing, but has been considered unpractical when samples may differ in unknown ways. This research explores the use of panelist derived terms to circumvent the need for researchers to identify these differences and compares the results to using research designated terms in discrimination testing. Results from this study can be utilized in creating ways to incorporate more powerful methods into sensory discrimination testing plans and provides researchers with a means for selecting terms for use in specified discrimination testing methods. PMID- 29178281 TI - Abdominal girth and dorso-sacral distance can be used to estimate lumbosacral cerebral fluid volume. AB - BACKGROUND: Patients' abdominal girth and vertebral column length are highly correlated with the spread of local anaesthetics after spinal anaesthesia. Lumbosacral cerebrospinal fluid volume is the primary determinant for spinal spread. Thus, we attempted to verify the hypothesis that abdominal girth and dorso-sacral distance are correlated with lumbosacral cerebrospinal fluid volume. METHODS: Forty-five healthy volunteers were enrolled in this study to measure lumbosacral cerebrospinal fluid volume using magnetic resonance imaging. The age, height, weight, abdominal girth, dorso-sacral distance and lumbosacral cerebrospinal fluid volume of the volunteers were recorded. Multiple linear regression analysis was used to analyse the correlation between age, height, weight, abdominal girth, dorso-sacral distance and lumbosacral cerebrospinal fluid volume. RESULTS: Two volunteers were excluded because of lumbar disc herniation, leaving 43 volunteers for analysis. Multiple linear regression analysis showed a strong correlation between abdominal girth, dorso-sacral distance and lumbosacral cerebrospinal fluid volume (both P < 0.01). The adjusted R2 was 0.644. Volunteers with small abdominal girth showed clear images of cerebrospinal fluid in the nerve root cuff at the intervertebral foramen in the three-dimensional magnetic resonance imaging reconstruction of lumbosacral cerebrospinal fluid, while the images were vague in volunteers with large abdominal girth. Clearer images implied larger lumbosacral cerebrospinal fluid volume, while vaguer images, smaller lumbosacral cerebrospinal fluid volume. CONCLUSIONS: Multiple regression analysis revealed that abdominal girth and dorso sacral distance were correlated with lumbosacral cerebrospinal fluid volume. Smaller abdominal girths and larger dorso-sacral distances predict larger lumbosacral cerebrospinal fluid volume. PMID- 29178282 TI - Adolescent Perceptions of Parental Privacy Invasion and Adolescent Secrecy: An Illustration of Simpson's Paradox. AB - Adolescents' secrecy is intertwined with perception of parents' behaviors as acts of privacy invasion. It is currently untested, however, how this transactional process operates at the within-person level-where these causal processes take place. Dutch adolescents (n = 244, Mage = 13.84, 38.50% boys) reported three times on perceived parental privacy invasion and secrecy. Cross-lagged panel models (CLPM) confirmed earlier findings. Privacy invasion predicted increased secrecy, but a reverse effect was found from increased secrecy to increased privacy invasion. Controlling for confounding positive group-level associations with a novel random intercept CLPM, negative within-person associations were found. Higher levels of secrecy predicted lower levels of privacy invasive behaviors at the within-person level. These opposing findings within- versus between-persons illustrate a Simpson's paradox. PMID- 29178283 TI - Insights into the epidemic characteristics and evolutionary history of the novel porcine circovirus type 3 in southern China. AB - Porcine circovirus type 3 (PCV3) is a newly identified circovirus from swine in the USA, China and Poland. This novel circovirus has been associated with porcine dermatitis and nephropathy syndrome (PDNS), reproductive failure and multisystemic inflammation; moreover, PCV3 poses a potential threat to the swine industry. In this retrospective study, a phylogenetic analysis was conducted to address the epidemiology and evolutionary dynamics of this novel circovirus. The total positive sample rate of PCV3 was 26.7% (76/285) and has increased gradually over the past 3 years. Of these PCV3-positive samples, 22.3% (17/76) were coinfected with PCV2. PCV3 can be detected in multiple sample types with different positive rates, and the positive rate is highest among stillborn. We also divide PCV3 into three clades (PCV3a, PCV3b and PCV3c) based on two amino acid mutations (A24V and R27K) on the cap protein in this study. In addition, the origin of PCV3 was approximately 1966 and may have originated from a bat associated circovirus. Our results suggested that PCV3 is widely distributed in southern China and has been circulating in swine herds for nearly half a century. PCV3 has evolved into different clades caused by mutations in cap proteins; thus, further research on PCV3 epidemiology should be conducted. PMID- 29178284 TI - Nitric oxide inhalations in bronchiolitis: A pilot, randomized, double-blinded, controlled trial. AB - AIM: The aims of this pilot study were to determine safety, tolerability (primary outcome) and efficacy (secondary outcome) of high-dose inhaled nitric oxide for the treatment of infants with moderately severe bronchiolitis. METHODS: This was a pilot, double-blinded, randomized controlled study (phase IIa). Intermittent inhalations of nitric oxide 160 ppm for 30 min or oxygen/air (control) were given 5 times/day to hospitalized infants (2-11 months) with acute bronchiolitis. Oxygen saturation, methemoglobin, and nitric dioxide (NO2 ) levels and vital signs were monitored. RESULTS: Forty-three infants were enrolled. Baseline characteristics were comparable in both study groups. Mean clinical score, comprised of four components: respiratory rate, use of accessory muscles, wheezes and crackles, and % room-air oxygen saturation, was 7.86 (+/-1.1) and 8.09 (+/ 1.2) in the NO and control groups, respectively, consistent with moderate severity. The overall frequency of adverse events was similar between the groups. Repeated nitric oxide inhalations did not result in increased inhaled NO2 levels or cumulative effect on methemoglobin levels. Secondary outcomes of efficacy were measured by length of hospitalization (LOS) in hours: LOS did not differ between groups. However, in a post-hoc analysis of a subgroup of infants hospitalized for >24 h (n = 24), the median LOS was shorter in the nitric oxide (41.9 h) than in the control group (62.5 h) (P = 0.014). CONCLUSION: Our study was unable to detect a difference in side effects using intermittent high-dose nitric-oxide inhalation or supportive treatment alone, in infants with moderate bronchiolitis. Preliminary efficacy outcomes are encouraging. PMID- 29178286 TI - Contrasting responses of crop legumes and cereals to nitrogen availability. AB - In nonagricultural systems, the relationship between intrinsic water-use efficiency (WUEi ) and leaf nitrogen (Narea ) is known to be stronger for legumes than for nonlegumes. We tested whether these relationships are retained for major agricultural legumes and nonlegumes. We compared the response to N nutrition of WUEi (and its component parts, photosynthesis (Asat ) and stomatal conductance (gs )) for legumes Cicer arietinum, Glycine max, Lupinus alba and Vicia faba, nonlegume dicots Brassica napus and Helianthus annus, and nonlegume cereals Hordeum vulgare and Triticum aestivum. Surprisingly, and in contrast to studied cereals and nonlegume dicots, Narea was positively related to photosynthesis in the legumes, explaining nearly half of the variance in Asat . WUEi was tightly coupled to Narea for agricultural legumes and nonlegume dicots, but not for cereal crops. Our analysis suggests that breeding efforts to reduce gs in legumes could increase WUEi by 120-218% while maintaining Asat at nonlegume values. Physiologically informed breeding of legumes can enhance sustainable agriculture by reducing requirements for water and N. PMID- 29178285 TI - Template-based quaternary structure prediction of proteins using enhanced profile profile alignments. AB - Proteins often exist as their multimeric forms when they function as so-called biological assemblies consisting of the specific number and arrangement of protein subunits. Consequently, elucidating biological assemblies is necessary to improve understanding of protein function. Template-Based Modeling (TBM), based on known protein structures, has been used widely for protein structure prediction. Actually, TBM has become an increasingly useful approach in recent years because of the increased amounts of information related to protein amino acid sequences and three-dimensional structures. An apparently similar situation exists for biological assembly structure prediction as protein complex structures in the PDB increase, although the inference of biological assemblies is not a trivial task. Many methods using TBM, including ours, have been developed for protein structure prediction. Using enhanced profile-profile alignments, we participated in the 12th Community Wide Experiment on the Critical Assessment of Techniques for Protein Structure Prediction (CASP12), as the FONT team (Group # 480). Herein, we present experimental procedures and results of retrospective analyses using our approach for the Quaternary Structure Prediction category of CASP12. We performed profile-profile alignments of several types, based on FORTE, our profile-profile alignment algorithm, to identify suitable templates. Results show that these alignment results enable us to find templates in almost all possible cases. Moreover, we have come to understand the necessity of developing a model selection method that provides improved accuracy. Results also demonstrate that, to some extent, finding templates of protein complexes is useful even for MEDIUM and HARD assembly prediction.

AB - AIMS: The aim of the present study was to assess the prevalence and risk factors of white oral mucosal lesions among Yemeni adults; in particular, those who chew khat and tobacco. METHODS: The present cross-sectional study included 1052 dental patients aged 15 years and older. A detailed oral examination was performed by a single examiner in accordance with standard international criteria. RESULTS: Overall, 25.2% of the study participants presented with one or more white lesions. The most prevalent lesions were khat-induced white lesion (8.8%), leukoedema (5.1%), and frictional keratosis (3.9%). Potentially malignant lesions, such as lichen planus, leukoplakia, and smokeless tobacco-induced lesions, were seen in 2.4%, 1.2%, and 1.7% of participants, respectively. Moreover, three cases of oral cancer were identified. The presence of white lesions was found to be significantly associated with advanced age (P = .004), male gender (P = .009), and khat/tobacco chewing habits (P < .001). CONCLUSIONS: The present study demonstrates a high prevalence of oral benign and potentially malignant white lesions. Further, it highlights the urgent need to develop and implement new government policies to regulate the sale of these products to reduce the prevalence of these lesions and the overall incidence of oral cancers in the Yemeni population. PMID- 29178290 TI - MicroRNA-21 Contributes to Reduced Microvascular Function in Binge Drinking Young Adults. AB - BACKGROUND: Binge drinking is associated with increased risk for cardiovascular (CV) disease. MicroRNA-21 (miR21) is up-regulated in the setting of excessive alcohol consumption and CV disease. Therefore, the goal of this study was to examine the vasodilatory responses to flow and acetylcholine (ACh) in the absence and presence of an anti-miR21 inhibitor in the microcirculation of young adult repeated binge drinkers (BDs). METHODS: Gluteal subcutaneous adipose tissue biopsies were obtained from young adults (18 to 30 years, n = 35 vessels from BDs and n = 28 vessels from abstainers). Resistance arteries (RAs) were isolated, incubated with anti-miR21 or a negative control (NC) to miR21 (12 hours; 50 nM), and lumen diameters measured with video microscopy. miR21 of adipose tissues was determined by quantitative polymerase chain reaction. RESULTS: Flow-induced dilation and ACh-induced dilation (AChID) were reduced in BDs as compared to abstainers. The miR21 inhibitor but not the NC abrogated these effects in BDs, but did not affect vasodilation in abstainers. Nitric oxide synthase inhibition with L-NAME reduced vasodilation in abstainers but not in BDs. In BDs, vasodilation was reduced by L-NAME in the presence of anti-miR21 but not the NC. Scavenging the reactive oxygen species, hydrogen peroxide with polyethylene glycol catalase reduced dilation in BDs but did not affect the restored dilation by the miR21 inhibitor. Maximum dilation to papaverine (endothelium independent) was similar between groups and unaffected by pharmacological inhibition. Finally, vascular endogenous miR21 was increased in BDs compared to abstainers. CONCLUSIONS: Endogenous miR21 is increased in RAs of young BDs, leading to reduced flow and AChID in the microcirculation. PMID- 29178289 TI - Simultaneous quantitative assessment of nine glycosides in tobacco by liquid chromatography-tandem mass spectrometry. AB - A simple and efficient method combining ultrasound-assisted extraction, the conditions of which were optimized by response surface methodology, with liquid chromatography and tandem mass spectrometry was established and validated for the absolute quantification of nine non-volatile neutral glycosides originating from tobacco (Nicotiana tobaccum L.) leaves, comprising three phenolic glycosides, one benzanoid glycoside, and five sesquiterpene glycosides within three isomers, originating from tobacco leaves. Factors of extraction time, sample quantity, extraction solvent, liquid chromatographic conditions, and electrospray ionization parameters were carefully investigated to ensure the selectivity and sensitivity of the method. All calibration curves showed excellent coefficients of determination ranging from 0.9940 to 0.9996, within the range of tested concentrations. The limits of detection and quantification were 2.33-25.9 and 7.06-78.5 ng/mL, respectively. Satisfactory values of accuracy were between 80.1 to 107.9% among different sample matrixes. The relative standard deviations of intra- and inter-day analysis were less than 13.7 and 13.0% respectively. The developed method was successfully applied in a pilot study to determine the amounts of the nine endogenous glycosides in real flue-cured tobacco samples obtained from different habitats in China. PMID- 29178291 TI - Polyhedral 30-Faceted BiVO4 Microcrystals Predominantly Enclosed by High-Index Planes Promoting Photocatalytic Water-Splitting Activity. AB - Unprecedented 30-faceted BiVO4 polyhedra predominantly surrounded by {132}, {321}, and {121} high-index facets are fabricated through the engineering of high index surfaces by a trace amount of Au nanoparticles. The growth of high-index facets results in a 3-5 fold enhancement of O2 evolution from photocatalytic water splitting by the BiVO4 polyhedron, relative to its low-index counterparts. Theory calculations reveal that water dissociation is more energetically favorable on the high-index surfaces than on the low-index (010), (110), and (101) surfaces, which is accompanied by a notable reduction in the overpotential (0.77-1.14 V) for the oxygen evolution reaction. The apparent quantum efficiency of O2 generation without an external electron supply reaches 18.3% under 430 nm light irradiation, which is an order of magnitude higher than that of the catalysts reported hitherto. PMID- 29178292 TI - Incubation media affect the survival, pathway and time of embryo development in Neotropical annual fish Austrolebias nigrofasciatus (Rivulidae). AB - To analyse the survival, pathway and time of embryo development in the annual fish Austrolebias nigrofasciatus eggs were monitored in four liquid media and two damp media under experimental conditions for 130 days until their development was complete. Eggs kept in the same breeding water from oviposition remained in diapause I (DI) during all experiments. In constrast, up to the stage prior to entering diapause II (DII), the other media had no influence on development. Embryos at this stage (DII), however, show longer development time when treated in medium with water and powdered coconut shell so that about 80% of embryos remained in DII at 100 days. In contrast, all other treatments had a significantly lower proportion of embryos remaining in DII. When treated with Yamamoto's solution in humid media, embryos showed the fastest development. The first fully developed embryos (DIII) were seen at 27 days after oviposition. It took an average of 46-58 days for 50% of eggs in each treatment to reach DIII. Compared with other studies, survival in all incubation media was high at between 70 and 98%. Taken together, it can be concluded that all incubation media were found to be viable for maintaining embryos. Altering developmental trajectories through the manipulation of diapauses in different media makes this species a potential model organism for laboratory studies.

PMID- 29178297 TI - Frontal plane hip joint loading according to pain severity in people with hip osteoarthritis. AB - The primary objective was to examine the hip adduction moment during walking in people with hip osteoarthritis (OA) according to pain severity. Sixty-eight participants with unilateral symptomatic hip OA were included. Pain during walking was assessed on a 5-point Likert item within the Western Ontario and McMaster Universities Index (no pain = 12; mild pain n = 37; moderate pain n = 19). Measures of the external hip adduction moment (peaks, Nm/BW * BH (%) and impulse, Nm.s/BW * BH (%)) were determined. Other measures included frontal plane hip, pelvis and trunk kinematics, walking speed and peak isometric hip abductor strength. Variables were compared according to pain severity using linear models and biomechanical variables were examined. Participants with moderate pain had a significantly higher second peak hip adduction moment and impulse compared to those with less pain. There was no difference in any measure of hip adduction moment between those with mild pain and no pain. There were no differences in kinematics across pain severity categories. Participants with moderate pain had a significantly slower walking speed compared to participants with mild and no pain. Participants with moderate pain had weaker peak isometric hip abductor strength compared to those with mild pain and no pain. The hip adduction moment during walking, hip abduction strength and walking speed differs according to pain severity during walking in people with hip OA. (c) 2017 Orthopaedic Research Society.

AB - Reactions of two vanadium(IV) complex anions that are homologues of amavadin, [V(HIDPA)2 ]2- and [V(HIDA)2 ]2- (HIDPA=N-oxyiminodipropionate, HIDA=N oxyiminodiacetate), with the nitrite ion (NO2- ) in aqueous solution were investigated by experimental (absorption spectroscopy in the visible range, through measurements of dioxygen formed in solution from water oxidation and identification of nitrogen oxide species of a gaseous atmosphere from nitrite reduction by using an IR analyser) and theoretical methods. Two reactions, mediated by the vanadium complexes, with environmental and biological significance, were observed in this system, namely, reduction of nitrite to N2 O and oxidation of water to molecular oxygen. The reduction of nitrite, as studied by DFT calculations, occurs through the formation of NO (DeltaG? =14.3 kcal mol-1 ), which is strongly dependent on pH and slightly endergonic, and is then easily converted into N2 O, with an overall activation barrier of DeltaG? =11.8 kcal mol 1 . The later process includes dimerisation of NO assisted by one molecule of the V complex, protonation and oxidation of the formed ONNO.- ligand by another amavadin molecule or by nitrite, and NO bond cleavage/proton transfer in the ONNOH- ligand. The results indicate that amavadin exhibits an unusual nitrite reductase type activity that could be involved in nitrogen metabolism of Amanita muscaria and other fungi containing this vanadium complex.

AB - Social capital plays a key role in college and career success, and research indicates that a dearth of on-campus connections contributes to challenges first generation college students face in effectively navigating the college environment. This study investigates a novel intervention that focuses on the development of skills and attitudes to empower first-generation college students to cultivate social capital and on-campus connections during the transition to college. A mixed methods, explanatory design was used to evaluate impacts and processes of the intervention among first-generation college students (n = 164) in the context of an ethnically diverse, urban, public university in the Northeast. Results indicated that students who participated in the intervention demonstrated improved attitudes and behaviors around seeking support in college, closer relationships with instructors, and higher GPAs at the end of their first year in college. These results suggest the potential benefits of a relatively scalable approach to supporting the needs of first-generation college students.

AB - Chiral properties of surface complexes based on CdSe/ZnS quantum dots (QDs) and 1 (2-pyridylazo)-2-naphthol (PAN) azo dye were investigated by circular dichroism spectroscopy. The use of L-, D-cysteine (Lcys, Dcys) capping ligands allowed us to obtain water-soluble chiral QD-PAN complexes. The characterization of the complexes was performed by UV-vis, FTIR, and CD spectroscopy. Quantum chemical TDDFT calculated CD spectra reproduced the experimentally observed sign patterns, which originate from binding Lcys or Dcys and PAN molecules to the same Zn atom on the QD surface. The resulting complex is characterized by a large circular dichroism in comparison with an ordinary QD chirality induced by cysteine molecules. The pattern of CD signal is the same for Lcys and Dcys ligands in chiral QD-PAN complex. PMID- 29178303 TI - AANEM Choosing Wisely - second list.

A two-phase solvent system composed of chloroform containing 0.10 mol/L of di-n-hexyl l-tartrate/0.10 mol/L of boric acid aqueous solution (1:1, v/v) was selected, in which 20 mmol/L triethylamine was added in the organic phase as a retainer and 2 mmol/L HCl was added in the aqueous phase as an eluter. Fifty milligrams of each racemate was completely enantioseparated by pH-zone refining countercurrent chromatography to yield each enantiomer with a purity of more than 98%, and the recovery of each separated enantiomer reached around 76 82%.

AB - Lung cancer invading the spine was previously considered unresectable and fatal and, consequently, there are few reports focusing on tumors located in the lower lung lobe and invading the spine. With the development of spinal instrumentation and surgical techniques, and wider acceptance of spondylectomy by surgeons, radical surgical resection has become feasible. Here, we present a case of a male patient with a left lower lung cancer invading thoracic vertebrae who underwent complete resection with sagittal en bloc hemivertebrectomy with video-assisted thoracoscopy. A 60-year-old man complained of left chest pain for 3 months. Chest computed tomography and thoracic vertebrae magnetic resonance image revealed that a tumor in the left lower lung lobe had invaded the seventh and eighth thoracic vertebrae and the eighth rib. As no lymph node or distant metastasis was detected by positron emission tomography-computed tomography, the patient was diagnosed with left lower lung cancer directly invading the seventh and eighth thoracic vertebrae and the eighth rib (T4N0M0, stage IIIA) instead of metastasizing to the thoracic vertebrae. An en bloc resection of the lung tumor and the involved vertebrae was performed by a thoracic surgeon and orthopaedic surgeon with video assisted thoracoscopy. Six months after the operation, there was no evidence of local recurrence, and the patient had recovered well. En Bloc resection with video-assisted thoracoscopy for lung cancer invading thoracic vertebrae is a safe and feasible surgical method. This method can significantly improve the safety and convenience of this type of surgery. PMID- 29178306 TI - Outcomes of Short Fusion versus Long Fusion for Adult Degenerative Scoliosis: A Systematic Review and Meta-analysis. AB - The objective of this study was to evaluate differences in clinical and radiographic outcomes between short (<3 levels) and long (>=3 levels) fusions in the setting of degenerative lumbar scoliosis. A literature search was performed from six electronic databases. The key terms of "degenerative scoliosis" OR "lumbar scoliosis" AND "fusion" were combined and used as MeSH subheadings. From relevant studies identified, demographic data, complication rates, Oswestry Disability Index (ODI), and radiographic parameters were extracted and the data was pooled and analyzed. Long fusion was associated with comparable overall complication rates to short fusion (17% vs 14%, P = 0.20). There was a significant difference in the incidence of pulmonary complications when comparing short versus long fusion (0.42% vs 2.70%; P = 0.02). No significant difference was found in terms of motor, sensory complications, infections, construct-related or cardiac complications, pseudoarthrosis, dural tears, cerebrospinal fluid (CSF) leak, or urinary retention. A longer fusion was associated with a greater reduction in coronal Cobb angle and increases in lumbar lordosis, but both findings failed to achieve statistical significance. The ODI was comparable across both cohorts. If shorter fusion lengths are clinically indicated, they should be used instead of longer fusion lengths to reduce perioperative time, costs, and some other complications. However, there are no statistically significant differences in terms of radiographically measurable restoration associated with a short or long fusion. PMID- 29178307 TI - Influence of Postoperative Hypertension on the Development of Spinal Epidural Hematoma. AB - Spinal epidural hematoma (SEH) is a rare postoperative complication but can result in catastrophic neurological deficits requiring immediate surgical evacuation of the hematoma. Knowing the risk factors for postoperative SEH can help surgeons stratify patients. Therefore, to identify possible risk factors for postoperative SEH, we reviewed 6 clinical cases and examined the relation between postoperative hypertension and the risk of developing SEH. A retrospective review was conducted of 1282 consecutive patients who underwent spinal surgery at a single institution between 2010 and 2015. Of this cohort, 6 patients developed symptomatic SEH and underwent emergency hematoma evacuation. The 6 SEH patients were evaluated for previously described risk factors of postoperative hematoma formation. In particular, postoperative blood pressure measurements were reviewed. The incidence of postoperative symptomatic SEH was 0.468%. Two patients developed SEH secondary to a nonfunctional surgical drain in the early postoperative period (5 or 12 h post-surgery). Preoperative and postoperative hypertension was observed in 4 patients who developed SEH at greater than or equal to 48 h following surgery. Our findings suggest that rigorous postoperative blood pressure control may decrease the risk of SEH. PMID- 29178308 TI - Effect of Intra-wound Vancomycin for Spinal Surgery: A Systematic Review and Meta analysis. AB - Intra-site prophylactic vancomycin in spine surgery is an effective method of decreasing the incidence of postsurgical wound infection. However, there are differences in the prophylactic programs used for various spinal surgeries. Thus, this systematic review and meta-analysis aimed to evaluate the effectiveness of using intra-wound vancomycin during spinal surgery and to explore the effects of dose-dependence and the method of administration in a subgroup analysis. A total of 628 citations or studies were searched in PubMed, Ovid, Web of Science, and Google Scholar that were published before August 2016 with the terms "local vancomycin", "intra-wound vancomycin", "intraoperative vancomycin", "intra-site vancomycin", "topical vancomycin", "spine surgery", and "spinal surgery". Finally, 19 retrospective cohort studies and one prospective case study were eligible for inclusion in the systematic review and meta-analysis. The odds of developing postsurgical wound infection without prophylactic local vancomycin use were 2.83-fold higher than the odds of experiencing wound infection with the use of intra-wound vancomycin (95% confidence interval, 2.03-3.95; P = 0.083; I2 = 32.2%). The subgroup analysis including the dosage and the method of administration, revealed different results compared to previous research. The value of I2 in the 1-g group was 27.2%, which was much lower than in the 2-g group (I2 = 57.6%). At the same time, the value of I2 was 0.0% (P = 0.792, OR = 2.70) when vancomycin powder was directly sprinkled into all layers of the wound. However, there is high heterogenicity (I2 = 60.0%, P = 0.007, OR = 2.83) when vancomycin powder is not exposed to the bone graft and instrumentation. There are differences found with the method of local application of vancomycin for reducing postoperative wounds and further studies are necessary, including investigations focusing on the dose-dependent effects during spinal or the topical pharmacokinetic and other orthopaedic surgeries. PMID- 29178309 TI - Antibiotic-loaded Bone Cement as Prophylaxis in Total Joint Replacement. AB - One of its most serious complications associated with arthroplasty is the development of infections. Although its prevalence is only between 0.5% and 3%, in some cases it can lead to death. Therefore, an important challenge in joint surgery is the prevention of infections when an arthroplasty is performed. The use of antibiotic-loaded cements could be a suitable tool due to numerous advantages. The main advantage of the use of antibiotic loading into bone cement derives directly from antibiotic release in the effect site, allowing achievement of high concentrations at the site of action, and minimal or no systemic toxicity. This route of administration was first described by Buchholz and Engelbrecht. In the case of infection treatment, this is an established method and its good results have been confirmed. However, its role in infection prevention, and, therefore, the use of these systems in clinical practice, has proved controversial because of the uncertainty about the development of possible antibiotic resistance after prolonged exposure time, their effectiveness, the cost of the systems, toxicity and loosening of mechanical properties. This review discusses all these topics, focusing on effectiveness and safety, antibiotic decisions, cement type, mixing method, release kinetics and future perspectives. The final objective is to provide the orthopaedic surgeons the right information in their clinical practice based on current evidence. PMID- 29178310 TI - A New Intraoperative Syndesmosis Instability Classification System: Utility and Medium-term Results in Closed Displaced Ankle Fractures. AB - OBJECTIVE: To investigate the utility and medium-term results of a new intra operative classification system for distal tibiofibular syndesmosis injury in ankle fractures. METHODS: Between January 2010 and January 2015, 116 patients diagnosed with displaced closed Weber B and C ankle fractures were treated in our department. The etiology of injury was 56 cases of fall-sprain, 36 of traffic injury, 14 of fall from a height, and 10 of multiple injuries. After fixation of the fibular fracture, we classify syndesmosis stability as either normal or one of three grades of instability using the fibular hook traction test. This determined further fixation selection and final syndesmosis treatment. RESULTS: Of 116 cases, 82 (71%) demonstrated a tibiofibular syndesmosis injury and 52 (45%) were unstable. Twenty-six cases were type I injuries (<4 mm displacement), 41% cases were type II injuries (4-7 mm displacement), and 3% of cases were type III injuries (>7 mm displacement). Types II and III are defined as unstable and require stabilization. Type III injuries have multiplanar instability and require two screws at the syndesmosis. Weber C fractures demonstrate significantly greater degrees of instability than Weber B fractures (chi2 = 15.50, P = 0.0014). All patients were followed up for 12-24 months, with no cases of non-union or broken screws. Good and excellent results were achieved in 93% of cases (according to the American Orthopaedic Foot and Ankle Society scoring system). CONCLUSION: The syndesmosis instability classification system provides a rational and efficient basis for managing syndesmosis instability. Our results from application of the algorithm justify its further evaluation in the treatment of patients with closed displaced Weber B and C ankle fractures. PMID- 29178311 TI - A Novel Approach for Reconstruction of Finger Neurocutaneous Defect: A Sensory Reverse Dorsal Digital Artery Flap from the Neighboring Digit. AB - OBJECTIVE: Providing soft tissue coverage for finger neurocutaneous defects presents aesthetic and sensory challenges. A common source for reconstruction of soft tissue defects of the fingers is the same finger. However, when the donor areas are damaged by concomitant injuries, this option is not available. The present study aims to reconstruct finger neurocutaneous defects using a sensory reverse dorsal digital artery flap from the neighboring digit and to evaluate the efficacy of this technique. METHODS: The study included 16 patients, with an average age of 34.9 years (range, 20-53 years) at the time of surgery, from May 2010 to June 2013. The sensory reverse dorsal digital artery flap was used in all 16 patients, who had a combination of soft tissue and digital nerve defects. The mean size of the soft tissue defects was 3.1 cm * 2.0 cm, and the mean flap size was 3.3 cm * 2.2 cm. The length of the nerve defects ranged from 1.3 to 2.5 cm (mean, 2.0 cm), which were reconstructed with dorsal branches of the proper digital nerve transfer. The active motion of the fingers (injured and donor) and the flap sensibility (static two-point discrimination) were measured. The appearance and functional recovery of the injured finger and the donor site were assessed using the Michigan Hand Outcomes Questionnaire. RESULTS: All flaps survived completely. No complications were reported, and no further flap debulking procedure was required. At the mean follow-up period of 24 months (range, 18-30 months), the mean static two-point discrimination was 6.5 mm (range, 5-10 mm) of the reconstructed area; the mean ranges of motions of the injured finger and the opposite finger at the proximal interphalangeal and distal interphalangeal joints were 102.2 degrees and 103.5 degrees , and 70.3 degrees and 76.5 degrees , respectively. The average ranges of motions of the metacarpophalangeal and proximal interphalangeal joints of the donor fingers were 90 degrees and 103.4 degrees , respectively. Based on the Michigan Hand Outcomes Questionnaire, 10 patients were strongly satisfied and 6 were satisfied with the functional recovery of the injured finger; however, 13 patients were strongly satisfied and 3 were satisfied with the appearance of the injured finger. CONCLUSION: The sensory reverse dorsal digital artery flap from the neighboring digit, based on the dorsal branch of the digital artery, is an effective and additional option for finger neurocutaneous defect reconstruction when use of the local and regional flaps is not feasible. PMID- 29178312 TI - Total Hip Arthroplasty in Hemophilia Patients: A Mid-term to Long-term Follow-up. AB - OBJECTIVE: To report the results of mid-term to long-term follow-up after primary total hip arthroplasty (THA) in hemophiliacs and to hypothesize that THA can provide satisfactory outcomes in these patients. METHODS: Twenty-four primary THA performed in 21 hemophilia patients between 2002 and 2012 were reviewed retrospectively, including 20 cases of hemophilia A and 1 case of hemophilia B. The standard lateral approach was used for all implantations. Substitution therapy for factor VIII and activated prothrombin complex concentrates were administered to patients with hemophilia A and B, respectively. Total and hidden blood loss were calculated. Outcomes were assessed using the Harris hip score before surgery and at the final follow-up visit. Complications were recorded by clinical and radiographic assessment and then compared to those in previous reports. RESULTS: The mean follow-up period was 113 months (range, 5-15 years). The average total blood loss was 3559 mL (range, 1494-7506 mL). The mean amount of red blood cell (RBC) transfusion was 4.4 U (range, 0-14 U). The mean amount of clotting factor used in the perioperative period for management of hemophilia was 14 031.3 U (range, 8100-25 200 U). Harris hip scores improved from 37 points (range, 15-81) before surgery to 90 points (range, 70-96) at the last follow-up. No signs of loosening, infection or other complications of the implant components occurred after discharge. The overall survivorship of the implants was 100% for all patients, and no revision surgery was performed. CONCLUSIONS: With modern techniques and hematological management, THA in patients with hemophilia leads to significant improvement in joint function with a relatively low incidence of complications. Increased blood loss and substitution therapy have no obvious negative influences on the mid-term to long-term results of THA. PMID- 29178313 TI - Association of Insulin-like Growth Factor-1, Bone Mass and Inflammation to Low energy Distal Radius Fractures and Fracture Healing in Elderly Women Attending Emergency Care. AB - OBJECTIVE: Elderly patients suffer fractures through low-energy mechanisms. The distal radius is the most frequent fracture localization. Insulin-like growth factor-1 (IGF1) plays an important role in the maintenance of bone mass and its levels decline with advancing age and in states of malnutrition. Our aim was to investigate the association of IGF1 levels, bone mass, nutritional status, and inflammation to low-energy distal radius fractures and also study if fracture healing is influenced by IGF1, nutritional status, and inflammation. METHODS: Postmenopausal women, 55 years or older, with low-energy distal radius fractures occurring due to falling on slippery ground, indoors or outdoors, were recruited in the emergency department (ED) and followed 1 and 5 weeks after the initial trauma with biomarkers for nutritional status and inflammation. Fractures were diagnosed according to standard procedure by physical examination and X-ray. All patients were conservatively treated with plaster casts in the ED. Patients who needed interventions were excluded from our study. Fracture healing was evaluated from radiographs. Fracture healing assessment was made with a five-point scale where the radiological assessment included callus formation, fracture line, and stage of union. Blood samples were taken within 24 h after fracture and analyzed in the routine laboratory. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry (DXA). RESULTS: Thirty-eight Caucasian women, aged 70.5 +/- 8.9 years (mean +/- SD) old, were recruited. Nutritional status, as evaluated by albumin (40.3 +/- 3.1 g/L), IGF1 (125.3 +/- 39.9 MUg/L), body mass index (26.9 +/ 3.6 kg/m2 ), arm diameter (28.9 +/- 8.9 cm), and arm skinfold (2.5 +/- 0.7 cm), was normal. A positive correlation was found between IGF1 at visit 1 and the lowest BMD for hip, spine, or radius (r = 0.39, P = 0.04). High sensitive C reactive protein (hsCRP) and leukocytes were higher at the fracture event compared to 5 weeks later (P = 0.07 and P < 0.001, respectively). Fracture healing parameters (i.e. callus formation, fracture line, and stage of union) were positively correlated with the initial leukocyte count and to difference in thrombocyte count between visit 1 and 3. CONCLUSIONS: In elderly women with low energy distal radius fractures, an association between IGF1 and lowest measures of BMD was found, indicating that low IGF1 could be an indirect risk factor for fractures. Fracture healing was associated with initial leukocytosis and a lower thrombocyte count, suggesting that inflammation and thrombocytes are important components in fracture healing. PMID- 29178314 TI - Perforated giant mycotic aneurysm of mitral valve in a drug-addicted young man: Rare complication of infective endocarditis. AB - Infective endocarditis (IE) affects patients at high clinical risk and may present as an acute and rapidly progressive, subacute or chronic infection. Transthoracic and transesophageal echocardiography represent the key diagnostic method in IE diagnosis. In particular, three-dimensional transesophageal echocardiography represents the imaging technique that allows to establish with adequate accuracy dimensions, shape, and localization of endocarditis vegetations. In our case, we show a huge vermiform mycotic aneurysm in an immunodeficient young drug-addicted man with severe mitral valve regurgitation and the additive value of three-dimensional transesophageal echocardiography in this specific clinical setting. PMID- 29178315 TI - 3D aggregate culture improves metabolic maturation of human pluripotent stem cell derived cardiomyocytes. AB - Three-dimensional (3D) cultures of human pluripotent stem cell derived cardiomyocytes (hPSC-CMs) hold great promise for drug discovery, providing a better approximation to the in vivo physiology over standard two-dimensional (2D) monolayer cultures. However, the transition of CM differentiation protocols from 2D to 3D cultures is not straightforward. In this work, we relied on the aggregation of hPSC-derived cardiac progenitors and their culture under agitated conditions to generate highly pure cardiomyocyte aggregates. Whole-transcriptome analysis and 13 C-metabolic flux analysis allowed to demonstrate at both molecular and fluxome levels that such 3D culture environment enhances metabolic maturation of hiPSC-CMs. When compared to 2D, 3D cultures of hiPSC-CMs displayed down-regulation of genes involved in glycolysis and lipid biosynthesis and increased expression of genes involved in OXPHOS. Accordingly, 3D cultures of hiPSC-CMs had lower fluxes through glycolysis and fatty acid synthesis and increased TCA-cycle activity. Importantly, we demonstrated that the 3D culture environment reproducibly improved both CM purity and metabolic maturation across different hPSC lines, thereby providing a robust strategy to derive enriched hPSC CMs with metabolic features closer to that of adult CMs. PMID- 29178316 TI - A comparison of accuracy validation methods for genomic and pedigree-based predictions of swine litter size traits using Large White and simulated data. AB - The objective of this study was to compare and determine the optimal validation method when comparing accuracy from single-step GBLUP (ssGBLUP) to traditional pedigree-based BLUP. Field data included six litter size traits. Simulated data included ten replicates designed to mimic the field data in order to determine the method that was closest to the true accuracy. Data were split into training and validation sets. The methods used were as follows: (i) theoretical accuracy derived from the prediction error variance (PEV) of the direct inverse (iLHS), (ii) approximated accuracies from the accf90(GS) program in the BLUPF90 family of programs (Approx), (iii) correlation between predictions and the single-step GEBVs from the full data set (GEBVFull ), (iv) correlation between predictions and the corrected phenotypes of females from the full data set (Yc ), (v) correlation from method iv divided by the square root of the heritability (Ych ) and (vi) correlation between sire predictions and the average of their daughters' corrected phenotypes (Ycs ). Accuracies from iLHS increased from 0.27 to 0.37 (37%) in the Large White. Approximation accuracies were very consistent and close in absolute value (0.41 to 0.43). Both iLHS and Approx were much less variable than the corrected phenotype methods (ranging from 0.04 to 0.27). On average, simulated data showed an increase in accuracy from 0.34 to 0.44 (29%) using ssGBLUP. Both iLHS and Ych approximated the increase well, 0.30 to 0.46 and 0.36 to 0.45, respectively. GEBVFull performed poorly in both data sets and is not recommended. Results suggest that for within-breed selection, theoretical accuracy using PEV was consistent and accurate. When direct inversion is infeasible to get the PEV, correlating predictions to the corrected phenotypes divided by the square root of heritability is adequate given a large enough validation data set. PMID- 29178317 TI - Community Program Improves Quality of Life and Self-Management in Older Adults with Diabetes Mellitus and Comorbidity. AB - OBJECTIVES: To compare the effect of a 6-month community-based intervention with that of usual care on quality of life, depressive symptoms, anxiety, self efficacy, self-management, and healthcare costs in older adults with type 2 diabetes mellitus (T2DM) and 2 or more comorbidities. DESIGN: Multisite, single blind, parallel, pragmatic, randomized controlled trial. SETTING: Four communities in Ontario, Canada. PARTICIPANTS: Community-dwelling older adults (>=65) with T2DM and 2 or more comorbidities randomized into intervention (n = 80) and control (n = 79) groups (N = 159). INTERVENTION: Client-driven, customized self-management program with up to 3 in-home visits from a registered nurse or registered dietitian, a monthly group wellness program, monthly provider team case conferences, and care coordination and system navigation. MEASUREMENTS: Quality-of-life measures included the Physical Component Summary (PCS, primary outcome) and Mental Component Summary (MCS, secondary outcome) scores of the Medical Outcomes Study 12-item Short-Form Health Survey (SF-12). Other secondary outcome measures were the Generalized Anxiety Disorder Scale, Center for Epidemiologic Studies Depression Scale (CES-D-10), Summary of Diabetes Self-Care Activities (SDSCA), Self-Efficacy for Managing Chronic Disease, and healthcare costs. RESULTS: Morbidity burden was high (average of eight comorbidities). Intention-to-treat analyses using analysis of covariance showed a group difference favoring the intervention for the MCS (mean difference = 2.68, 95% confidence interval (CI) = 0.28-5.09, P = .03), SDSCA (mean difference = 3.79, 95% CI = 1.02-6.56, P = .01), and CES-D-10 (mean difference = -1.45, 95% CI = 0.13 to -2.76, P = .03). No group differences were seen in PCS score, anxiety, self-efficacy, or total healthcare costs. CONCLUSION: Participation in a 6-month community-based intervention improved quality of life and self-management and reduced depressive symptoms in older adults with T2DM and comorbidity without increasing total healthcare costs. PMID- 29178318 TI - Thyroid cancer patients receiving an interdisciplinary team-based care approach (ITCA-ThyCa) appear to display better outcomes: Program evaluation results indicating a need for further integrated care and support. AB - BACKGROUND: Thyroid cancer (ThyCa) is generally associated with a favorable prognosis and excellent surgical outcomes. Consequently, its treatment is medically focused and current guidelines recommend interdisciplinary care including access to a nurse for complex cases alone. To date, no studies have evaluated the need for and impact of an Interdisciplinary Team-based Care Approach (ITCA-ThyCa) for general thyroid cancer patients, including a dedicated nurse as part of a larger interdisciplinary team, as well as patient-reported outcomes, as is recommended worldwide in cancer care. Our aim was to evaluate such a program. METHODS: The ITCA-ThyCa was evaluated within a quasi-experimental design using the Centers for Disease Control Framework for Program Evaluation, including process and outcome measures. Patients eligible were adults with a biopsy indicating confirmed or highly suspicious ThyCa (TNM-Classification + Bethesda score of V/VI). The intervention group (IG) received ITCA-ThyCa and the comparison group (CG), usual care alone. RESULTS: In our sample comprised of 200 participants (122 IG; 78 CG), ITCA-ThyCa patients appeared to show significantly better outcomes than CG patients, namely, higher levels of overall well-being (P = .001) and fewer physical (P = .003) and practical (P = .003) issues and concerns. More satisfied with their overall care (P = .028), including care coordination (P = .049), they reported their health care provider as more approachable (P = .007), respectful (P = .005), and trustworthy (P = .077; trend) and were more likely to recommend their hospital (P = .02). Ninety-eight percent of IG patients recommended ITCA-ThyCa. CONCLUSION: Data from our program illustrates that hospital resources should not be allocated based on medical trajectory alone and challenges the idea that ThyCa is "straightforward." ThyCa patients seem to experience symptom distress at a level comparable to-or exceeding-that of general oncological patients despite their promising medical outcomes, indicating that better integrated care and support are in order. PMID- 29178319 TI - Thyroid hormone upregulates MDM2 in rat type I fibre: Implications for skeletal muscle mass regulation. AB - AIM: Based upon a microarray assay, we have identified that triiodothyronine (T3) upregulates MDM2 gene expression in the rat skeletal muscle. As MDM2 protein is an E3 ligase, we hypothesized that this enzyme could play a role in T3 effects on skeletal muscle mass control. METHODS: To test our hypothesis, male rats (2 months old) were randomly assigned into the following groups: intact controls, treated with 20 physiological doses of T3 for 0.5, 1 and 7 days, or with 5, 20 and 50 physiological doses of T3 for 7 days. For in vitro experiments, myotubes and C2C12 cells were treated with T3 for 3 days. RESULTS: After validation of the microarray finding throughout RT-PCR and confirmation that T3 induces increases in MDM2 protein expression in a dose-dependent manner, we observed that MDM2 was upregulated by T3 exclusively in fibre type I. Moreover, detailed histological evaluation showed that MDM2 overexpression distributes punctiformily along the cross section of the fibre and also inside nuclei. MDM2 colocalizes with PAX7 in control muscle and T3 downregulates this myogenic factor. Pharmacological inhibition of MDM2 in cultured myotubes caused a severe decrease in their diameter (~35%, P < .001 vs Control), enhancing the effect of T3 (from ~12% to ~35%, P < .001) alone upon myotube diameter and mRNA levels of atrogenes. Finally, we observed that FOXO3 (MDM2 target) is kept outside the nucleus under T3 stimulation. CONCLUSION: Our results indicate that MDM2 might be involved in the pro-trophic effects of T3 in skeletal muscle. PMID- 29178320 TI - Low-oxygen conditions promote synergistic increases in chondrogenesis during co culture of human osteoarthritic stem cells and chondrocytes. AB - There has been increased interest in co-cultures of stem cells and chondrocytes for cartilage tissue engineering as there are the limitations associated with using either cell type alone. Drawbacks associated with the use of chondrocytes include the limited numbers of cells available for isolation from damaged or diseased joints, their dedifferentiation during in vitro expansion, and a diminished capacity to synthesise cartilage-specific extracellular matrix components with age and disease. This has motivated the use of adult stem cells with either freshly isolated or culture-expanded chondrocytes for cartilage repair applications; however, the ideal combination of cells and environmental conditions for promoting robust chondrogenesis remains unclear. In this study, we compared the effect of combining a small number of freshly isolated or culture expanded human chondrocytes with infrapatellar fat pad-derived stem cells (FPSCs) from osteoarthritic donors on chondrogenesis in altered oxygen (5% or 20%) and growth factor supplementation (TGF-beta3 only or TGF-beta3 and BMP-7) conditions. Both co-cultures, but particularly those including freshly isolated chondrocytes, were found to promote cell proliferation and enhanced matrix accumulation compared to the use of FPSCs alone, resulting in the development of a tissue that was compositionally more similar to that of the native articular cartilage. Local oxygen levels were found to impact chondrogenesis in co-cultures, with more robust increases in proteoglycan and collagen deposition observed at 5% O2 . Additionally, collagen type I synthesis was suppressed in co-cultures maintained at low-oxygen conditions. This study demonstrates that a co-culture of freshly isolated human chondrocytes and FPSCs promotes robust chondrogenesis and thus is a promising cell combination for cartilage tissue engineering. PMID- 29178322 TI - Literacy analysis of National Comprehensive Cancer Network patient guidelines for the most common malignancies in the United States. AB - BACKGROUND: Cancer information is of critical interest to the public. The National Comprehensive Cancer Network (NCCN) offers a series of comprehensive patient guidelines on the management of the most common cancer diagnoses. This study was aimed at assessing the health literacy demands of NCCN patient guidelines for the most common malignancies in the United States. METHODS: The American Cancer Society's most common malignancies by annual incidence in the United States and their corresponding NCCN patient guidelines were identified. Four validated tools were used to evaluate literacy levels: 1) the Simple Measure of Gobbledygook, 2) the Peter Mosenthal and Irwin Kirsch readability formula (PMOSE/IKIRSCH), 3) the Patient Education Materials Assessment Tool (PEMAT), and 4) the Clear Communication Index from the Centers for Disease Control and Prevention (CDC). RESULTS: The average reading grade level was 10.3, which was higher than the recommended 6th-grade level. The average PMOSE/IKIRSCH score was 11; this corresponded to moderate complexity and required some college-level education for interpretation. Only 1 tool, the PEMAT, yielded scores above the benchmarks for high-quality materials. The PEMAT's understandability, actionability, and overall scores were 94%, 83%, and 91%, respectively. The average CDC index was 85%, which was below the recommended 90% for an appropriate health literacy demand. CONCLUSIONS: Overall, the assessment indicates high demand scores for the readability and complexity of the NCCN patient guidelines and thus that the materials are not quite suitable for the general US adult population. Further input from patient focus groups to address appropriateness and usefulness is critical. Cancer 2018;124:769-74. (c) 2017 American Cancer Society. PMID- 29178321 TI - Glial hypothalamic inhibition of GLUT2 expression alters satiety, impacting eating behavior. AB - Glucose is a key modulator of feeding behavior. By acting in peripheral tissues and in the central nervous system, it directly controls the secretion of hormones and neuropeptides and modulates the activity of the autonomic nervous system. GLUT2 is required for several glucoregulatory responses in the brain, including feeding behavior, and is localized in the hypothalamus and brainstem, which are the main centers that control this behavior. In the hypothalamus, GLUT2 has been detected in glial cells, known as tanycytes, which line the basal walls of the third ventricle (3V). This study aimed to clarify the role of GLUT2 expression in tanycytes in feeding behavior using 3V injections of an adenovirus encoding a shRNA against GLUT2 and the reporter EGFP (Ad-shGLUT2). Efficient in vivo GLUT2 knockdown in rat hypothalamic tissue was demonstrated by qPCR and Western blot analyses. Specificity of cell transduction in the hypothalamus and brainstem was evaluated by EGFP-fluorescence and immunohistochemistry, which showed EGFP expression specifically in ependymal cells, including tanycytes. The altered mRNA levels of both orexigenic and anorexigenic neuropeptides suggested a loss of response to increased glucose in the 3V. Feeding behavior analysis in the fasting feeding transition revealed that GLUT2-knockdown rats had increased food intake and body weight, suggesting an inhibitory effect on satiety. Taken together, suppression of GLUT2 expression in tanycytes disrupted the hypothalamic glucosensing mechanism, which altered the feeding behavior.

Synthesized through the use of different cobalt salt anions and solvents, five complexes, namely [CoII4 CoIII3 (H2 L)3 Cl5 (MeOH)] (1), [CoII4 CoIII3 (H2 L)3 (CH3 COO)4 (HCOO)?H2 O]n (2), [CoII4 CoIII3 (H2 L)3 (HCOO)4 (NO3 )?2H2 O]n (3), [CoII4 CoIII3 (H2 L)3 (bda)(CH3 COO)4 ?2H2 O]n (4), and [CoII4 CoIII3 (H2 L)3 (ipa)(HCOO)3 (dmf)?H2 O]n (5) (H6 L=bis-tris propane; BDA=biphenyl 4,4'-dicarboxylic acid; IPA=isophthalic acid; DMF=N,N-dimethylformamide), based on the heptanuclear {CoII4 CoIII3 } cluster with structures from 0D to 3D metal organic frameworks (MOFs) have been solvothermally synthesized. Compound 1 is the first 0D heptanuclear cluster based on H6 L. Compound 2 crystallizes in the chiral space group P21 21 21 and consists of a 1D chiral helical chain. Complex 3 exhibits a 3D network structure. Compound 4 possesses a 1D zigzag-like chain structure. Finally, compound 5 was obtained as a 3D microporous structure. Compounds 1, 3, and 4 display dominant ferrimagnetic interactions whereas compounds 2 and 5 exhibit antiferromagnetic interactions. Moreover, the Co3 O4 prepared by calcining compound 2 presents a reversible capacity of 1122.9 mA h g 1 at 0.2 A g-1 after 100 cycles and an excellent rate capability, which suggests that coordination compounds with a 1D chain structure are outstanding precursors for preparing anode materials for lithium ion batteries.

AB - The lipolysis stimulated lipoprotein receptor (LSR) is an apolipoprotein (Apo) B and ApoE receptor that participates in the removal of triglyceride-rich lipoproteins during the postprandial phase. LSR gene is located upstream of APOE, an important risk factor for cardiovascular disease (CVD). Since the APOE common polymorphism significantly affects the variability of lipid metabolism, this study aimed to determine the potential impact of a functional SNP rs916147 in LSR gene on lipid traits in healthy subjects and to investigate potential epistatic interaction between LSR and APOE. Unrelated healthy adults (N = 432) and children (N = 328, <18 years old) from the STANISLAS Family Study were used. Age-specific epistasis was observed between APOE and LSR, reversing the protective effect of APOE epsilon2 allele on cholesterol, ApoE and low-density lipoprotein levels (beta: .114, P: .777 * 10-8 , beta: .125, P: .639 * 10-3 , beta: .059, P: .531 * 10-3 , respectively). This interaction was verified in an independent adult population (n = 1744). These results highlight the importance of the LSR polymorphism and reveal the existence of complex molecular links between LSR and ApoE for the regulation of lipid levels, revealing potential new pathways of interest in type III hyperlipidemia and its involvement in CVD pathology.

PMID- 29178326 TI - Anatomy of genital reaffirmation surgery (male-to-female): Vaginoplasty using penile skin graft with scrotal flaps. AB - Gender reaffirmation surgery is the final step in an individual's transition to their preferred gender. A clear understanding of the anatomy pertinent to this procedure is essential by the surgeon and patient. In male-to-female transgenders, female genitalia is constructed using the individual's penile skin to form the neovaginal canal and their scrotal skin folds post orchiectomy to create the labia majora. The surgical precursors of the remaining anatomical structures of the female genitalia are as follows: the clitoris is crafted from the glans penis and hence retains its innervation, the labia minora is formed using excess penile skin tissue, and the long male urethra is shortened to that of its feminine counterpart. The main goal of these reconstructive methods is to create a functionally and aesthetically acceptable vagina and vulva, as well as normal voiding function and satisfactory sexual function. Surgical text descriptions were enhanced by the creation of new anatomic illustrations. Review of the relevant literature regarding the anatomy, procedure development, and outcomes is presented. Vaginoplasty utilizing penile skin grafts with scrotal flaps provides an aesthetically acceptable and psychologically satisfying results with normal voiding and sexual function. An advantage includes preserved erogenous sensation. Complications can arise, including chronic inflammation and fistula formation. The anatomy of vaginoplasty using penile skin grafts with scrotal flaps supports patients seeking male-to-female gender reaffirmation surgery. Clin. Anat. 31:140-144, 2018.

PMID- 29178328 TI - Mineralocorticoid receptor blockade improves glucocorticoid-induced skin atrophy but partially ameliorates anti-inflammatory actions in an irritative model in human skin explants. AB - We recently demonstrated that blockade of the mineralocorticoid receptor (MR) effectively ameliorated GC-induced skin atrophy in healthy human skin explants and epidermal MR knockout mice. However, whether MR blockade improves the therapeutic index of glucocorticoids (GCs) in skin pathology was not investigated. We assessed the effects of GCs, MR antagonists (MRA) or both, in SDS-treated human skin explants. All treatments restored SDS-augmented epidermal thickness but only GC plus MRA restored the expression of COL1A1. However, MRA alone or in combination with GCs may exert a dual role in regulating inflammatory cytokines. Thus, although combined treatment may be beneficial to improve irritative skin, extensive in vivo testing is required to establish whether the anti-inflammatory effects of GCs are maintained in the presence of MRA.

AB - There is strong evidence of a key role for mitochondrial dysfunction in both sporadic and all forms of familial Parkinson's disease (PD). However, none of the clinical trials carried out with putative mitochondrial rescue agents have been successful. Firm establishment of a wet biomarker or a reliable readout from imaging studies detecting mitochondrial dysfunction and reflecting disease progression is also awaited. We will provide an overview of our current knowledge about mitochondrial dysfunction in PD and related drug screens. We will also summarise previously undertaken mitochondrial wet biomarker studies and relevant imaging studies with particular focus on 31P-MRI spectroscopy. We will conclude with an overview of clinical trials which tested putative mitochondrial rescue agents in PD patients. PMID- 29178331 TI - Response to: bullous pemphigoid inguinalis? PMID- 29178332 TI - Eating disorders in people with Type 1 diabetes: experiential perspectives of both clients and healthcare professionals. AB - AIMS: To explore the experiential perspective of people with Type 1 diabetes mellitus and eating disorders and that of the healthcare professionals treating them, and to understand the experience of both sides to inform future development of healthcare services. METHODS: Participants were recruited from Diabetics with Eating Disorders (a national UK charity), and through professional networks. Nine partially/fully recovered individuals with Type 1 diabetes and eating disorders and eight healthcare professionals participated in semi-structured interviews carried out by medically trained researchers. Data were transcribed and coded using a six-stage framework of thematic analysis. RESULTS: Four superordinate themes and several subordinate themes emerged from the Type 1 diabetes and eating disorders dataset: (1) perceptions surrounding service provision; (2) reflections on the recovery process; (3) the experiential perspective of living with Type 1 diabetes and an eating disorder; and (4) support mechanisms. Healthcare professional data elicited three superordinate themes and several subordinate themes: (1) service provision; (2) personal insight and reflection of professional role; and (3) challenges of working with dual diagnoses. CONCLUSION: People with Type 1 diabetes and eating disorders and their healthcare professionals provided insight into healthcare services from the patient and care delivery perspectives. There was general agreement from both groups that a multidisciplinary, collaborative (family inclusive), clinical approach to treatment is important, as well as adequate training opportunities for service providers. These findings may help to inform development strategies for multidisciplinary care approaches to Type 1 diabetes complicated by eating disorders. PMID- 29178333 TI - Model-Based Reverse Translation Between Veterinary and Human Medicine: The One Health Initiative. AB - There is growing concern about the limitations of rodent models with regard to recapitulation of human disease pathogenesis. Computational modeling of data from humans and animals sharing similar diseases provides an opportunity for parallel drug development in human and veterinary medicine. This "reverse translational" approach needs to be supported by continuing efforts to refine the in silico tools that allow extrapolation of results between species. PMID- 29178334 TI - Suppression of oxidative phosphorylation confers resistance against bevacizumab in experimental glioma. AB - Although bevacizumab initially shows high response rates in gliomas and other tumours, therapy resistance usually develops later. Because anti-angiogenic agents are supposed to induce hypoxia, we asked whether rendering glioma cells independent of oxidative phosphorylation modulates their sensitivity against hypoxia and bevacizumab. LNT-229 glioma cells without functional mitochondria (rho0 ) and control (rho+ ) cells were generated. LNT-229 rho0 -cells displayed reduced expression of oxidative phosphorylation-related genes and diminished oxygen consumption. Conversely, glycolysis was up-regulated in these cells, as shown by increased lactate production and stronger expression of glucose transporter-1 and lactate dehydrogenase-A. However, hypoxia-induced cell death in vitro was nearly completely abolished in the LNT-229 rho0 -cells, these cells were more sensitive towards glucose restriction and the treatment with the glycolysis inhibitor 2-deoxy-D-glucose. In an orthotopic mouse xenograft experiment, bevacizumab induced hypoxia as reflected by elevated Hypoxia inducible factor 1-alpha staining in both, rho+ - and rho0 -tumours. However, it prolonged survival only in the mice bearing rho+ -tumours (74 days vs. 105 days, p = 0.024 log-rank test) and had no effect on survival in mice carrying LNT-229 rho0 -tumours (75 days vs. 70 days, p = 0.52 log-rank test). Interestingly, inhibition of glycolysis in vivo with 2-deoxy-D-glucose re-established sensitivity of rho0 -tumours against bevacizumab (98 days vs. 80 days, p = 0.0001). In summary, ablation of oxidative phosphorylation in glioma cells leads to a more glycolytic and hypoxia-resistant phenotype and is sufficient to induce bevacizumab-refractory tumours. These results add to increasing evidence that a switch towards glycolysis is one mechanism how tumour cells may evade anti angiogenic treatments and suggest anti-glycolytic strategies as promising approaches to overcome bevacizumab resistance. PMID- 29178335 TI - A General Synthesis of Porous Carbon Nitride Films with Tunable Surface Area and Photophysical Properties. AB - Graphitic carbon nitride (g-CN) has emerged as a promising material for energy related applications. However, exploitation of g-CN in practical devices is still limited owing to difficulties in fabricating g-CN films with adjustable properties and high surface area. A general and simple pathway is reported to grow highly porous and large-scale g-CN films with controllable chemical and photophysical properties on various substrates using the doctor blade technique. The growth of g-CN films, ascribed to the formation of a supramolecular paste, comprises g-CN monomers in ethylene glycol, which can be cast on different substrates. The g-CN composition, porosity, and optical properties can be tuned by the design of the supramolecular paste, which upon calcination results in a continuous porous g-CN network. The strength of the porous structure is demonstrated by high electrochemically active surface area, excellent dye adsorption and photoelectrochemical and photodegradation properties. PMID- 29178336 TI - Taking error into account when fitting models using Approximate Bayesian Computation. AB - Stochastic computer simulations are often the only practical way of answering questions relating to ecological management. However, due to their complexity, such models are difficult to calibrate and evaluate. Approximate Bayesian Computation (ABC) offers an increasingly popular approach to this problem, widely applied across a variety of fields. However, ensuring the accuracy of ABC's estimates has been difficult. Here, we obtain more accurate estimates by incorporating estimation of error into the ABC protocol. We show how this can be done where the data consist of repeated measures of the same quantity and errors may be assumed to be normally distributed and independent. We then derive the correct acceptance probabilities for a probabilistic ABC algorithm, and update the coverage test with which accuracy is assessed. We apply this method, which we call error-calibrated ABC, to a toy example and a realistic 14-parameter simulation model of earthworms that is used in environmental risk assessment. A comparison with exact methods and the diagnostic coverage test show that our approach improves estimation of parameter values and their credible intervals for both models. PMID- 29178337 TI - Roll-to-Roll Production of Layer-Controlled Molybdenum Disulfide: A Platform for 2D Semiconductor-Based Industrial Applications. AB - A facile methodology for the large-scale production of layer-controlled MoS2 layers on an inexpensive substrate involving a simple coating of single source precursor with subsequent roll-to-roll-based thermal decomposition is developed. The resulting 50 cm long MoS2 layers synthesized on Ni foils possess excellent long-range uniformity and optimum stoichiometry. Moreover, this methodology is promising because it enables simple control of the number of MoS2 layers by simply adjusting the concentration of (NH4 )2 MoS4 . Additionally, the capability of the MoS2 for practical applications in electronic/optoelectronic devices and catalysts for hydrogen evolution reaction is verified. The MoS2 -based field effect transistors exhibit unipolar n-channel transistor behavior with electron mobility of 0.6 cm2 V-1 s-1 and an on-off ratio of ~103. The MoS2 -based visible light photodetectors are fabricated in order to evaluate their photoelectrical properties, obtaining an 100% yield for active devices with significant photocurrents and extracted photoresponsivity of ~22 mA W-1 . Moreover, the MoS2 layers on Ni foils exhibit applicable catalytic activity with observed overpotential of ~165 mV and a Tafel slope of 133 mV dec-1 . Based on these results, it is envisaged that the cost-effective methodology will trigger actual industrial applications, as well as novel research related to 2D semiconductor based multifaceted applications. PMID- 29178338 TI - Disorder- and Treatment-Specific Therapeutic Competence Scales for Posttraumatic Stress Disorder Intervention: Development and Psychometric Properties. AB - Although the assessment of therapeutic competence in psychotherapy research is essential for examining its possible associations with treatment outcomes, it is often neglected due to high costs and a lack of valid instruments. This study aimed to develop two therapeutic competence scales that assess disorder-specific and treatment-specific therapeutic competence, and to examine these scales' psychometric properties along with those of the already established Cognitive Therapy Scale (CTS) in a posttraumatic stress disorder (PTSD) sample. Using an inductive procedure, two rating scales for assessing disorder-specific and treatment-specific competence were constructed. The psychometric properties of these scales and those of the CTS were assessed in a sample of 30 videotaped sessions of eight patients from a multicenter study in which PTSD related to child abuse was treated using cognitive processing therapy. Two raters assessed therapeutic competence in 30 videotaped psychotherapy sessions. Interrater reliability, internal consistency, and content validity were determined. The scales (all items and total scores) demonstrated good to excellent interrater reliability, intraclass correlation coefficients (ICCs) = .67 to .97, and internal consistency, Cronbach's alpha = .73 to .92. The PTSD experts' ratings confirmed good internal validity. We found statistically significant associations with therapeutic adherence, r = .62 to .85; p < .001; and therapeutic alliance, r = .47, p < .001. These preliminary data imply that the two newly developed competence scales and the CTS can be reliably used to assess different types of therapeutic competence in PTSD samples and may be useful as possible predictors of treatment outcomes. PMID- 29178339 TI - Chemical Constituents of Sweetpotato Genotypes in Relation to Textural Characteristics of Processed French Fries. AB - : Sweetpotato French fries (SPFF) are growing in popularity, however limited information is available on SPFF textural properties in relation to chemical composition. This study investigated the relationship between chemical components of different sweetpotato varieties and textural characteristics of SPFF. Sixteen sweetpotato genotypes were evaluated for (1) chemical constituents; (2) instrumental and sensory textural properties of SPFF; and (3) the relationship between chemical components, instrumental measurements, and sensory attributes. Dry matter (DM), alcohol-insoluble solids (AIS), starch, sugar, and oil content, and also alpha- and beta-amylase activities were quantified in raw sweetpotatoes and SPFF. Peak force and overall hardness describing instrumental textural properties of SPFF were measured using a texture analyzer. Descriptive sensory analysis was conducted and 10 attributes were evaluated by a trained panel. Results showed that DM, AIS, and starch content in raw sweetpotatoes were significantly correlated (P < 0.05) with instrumental peak force and overall hardness (r = 0.41 to 0.68), and with sensory surface roughness, hardness, fracturability, and crispness (r = 0.63 to 0.90). Total sugar content in raw sweetpotatoes was positively correlated with sensory smoothness and moistness (r = 0.77), and negatively correlated with instrumental peak force and overall hardness (r = -0.62 to -0.69). Instrumental measurements were positively correlated with sensory attributes of hardness, fracturability, and crispness (r = 0.68 to 0.96) and negatively correlated with oiliness, smoothness, moistness, and cohesiveness (r = -0.61 to -0.91). Therefore, DM, AIS, starch, and total sugar contents and instrumental measurements could be used as indicators to evaluate sweetpotato genotypes for SPFF processing. PRACTICAL APPLICATION: In recent years, sweetpotato French fries (SPFF) have grown in popularity, but limited information is available on SPFF textural properties in relation to the differences in chemical constituents among sweetpotato varieties. This study demonstrated that sensory texture attributes of SPFF varied widely and were significantly correlated with chemical components such as dry matter, starch, and total sugar contents of raw sweetpotatoes and instrumental texture measurements of SPFF. The knowledge generated from this study will benefit the food industry and breeding programs with the selection of sweetpotato varieties for improved SPFF quality. PMID- 29178340 TI - Spring-damper equivalents of the fractional, poroelastic, and poroviscoelastic models for elastography. AB - In MR elastography, it is common to use an elastic model for the tissue's response in order to interpret the results properly. More complex models, such as viscoelastic, fractional viscoelastic, poroelastic, or poroviscoelastic ones, are also used. These models appear at first sight to be very different, but here it is shown that they may all be expressed in terms of elementary viscoelastic models. For a medium expressed with fractional models, many elementary spring damper combinations are added, each of them weighted according to a long-tailed distribution of time constants or relaxation frequencies. This may open up a more physical interpretation of fractional models. The shear-wave component of the poroelastic model is shown to be modeled exactly by a three-component Zener model. The extended poroviscoelastic model is found to be equivalent to what is called a non-standard four-parameter model. Accordingly, the large number of parameters in the porous models can be reduced to the same number as in their viscoelastic equivalents. While the individual displacements from the solid and fluid parts cannot be measured individually, the main use of the poro(visco)elastic models is therefore as a physics-based method for determining parameters in a viscoelastic model. PMID- 29178341 TI - Persistence of contact allergy: a retrospective analysis. AB - BACKGROUND: Studies have shown that not all positive patch test reactions are reproducible upon retesting, that is, persistent. Non-persistent reactions might represent initial false-positive reactions, meaning that patients might unnecessarily avoid allergens. OBJECTIVES: To investigate the occurrence of both persistent and non-persistent patch test reactions, to explore possible explanations, and to investigate whether allergen-specific differences exist. METHODS: A retrospective analysis was performed on patients who were patch tested at least twice between 1 January 1995 and 31 October 2016, with at least one positive patch test reaction to an allergen that had been retested. Both univariable and multivariable analyses were performed to investigate the influence of several factors on persistence. RESULTS: Of 274 retested positive reactions in 119 patients, 183 (66.8%) reactions remained positive. The strongest predictor for non-persistence in both univariable and multivariable analyses was strength of the first patch test, with weak positive reactions being significantly less persistent. Regarding allergen groups, metals and fragrances were less persistent than other allergens. CONCLUSION: Weak positive reactions have a low persistence rate, and the dermatologist should be conservative in advising the patient on avoidance of these allergens, especially if clinical relevance is uncertain. PMID- 29178342 TI - MicroRNA-145 regulates disabled-2 and Wnt3a expression in cardiomyocytes under hyperglycaemia. AB - AIMS: MicroRNA-145 (miR-145) could protect cardiomyocyte apoptosis against oxidative stress and repair infarcted myocardium. Angiotensin II (Ang II), a pro inflammatory cytokine could modulate myocardial remodelling. However, the role of hyperglycaemia on miR-145 expression in cardiomyocyte or diabetes is not known. The effect of Ang II on miR-145 expression under hyperglycaemia in cardiomyocytes remains unknown. We sought to investigate the effect of hyperglycaemia and Ang II on miR-145 expression in cardiomyocytes. METHODS: Rat cardiomyocytes were cultured under high glucose concentration (25 mmol/L), and streptozotocin-induced diabetic rats were established. TaqMan(r) MicroRNA real-time quantitative assay was used to quantitate miR-145. RESULTS: Sustained high glucose concentration (hyperglycaemia) significantly decreased miR-145 expression in cardiomyocytes. Hyperglycaemia significantly increased Ang II mRNA expression and secretion from rat cardiomyocytes. Ang II suppressed miR-145 expression in cardiomyocytes. Hyperglycaemia increased Dab2 and decreased Wnt3a/beta-catenin expression in cardiomyocytes. Repression of miR-145 expression by Ang II resulted in increased Dab2 and decreased Wnt3a and beta-catenin expression under hyperglycaemia. In contrast, overexpression of miR-145 significantly decreased Dab2 mRNA and protein expression, whereas the mRNA and protein levels for Wnt3a and beta-catenin were significantly reduced in left ventricular myocardium from 5 days to 28 days in diabetic rats. The protein expression patterns of Dab2 and Wnt3a/beta-catenin in left ventricular myocardium of diabetic rats could be reversed upon treatment with valsartan. CONCLUSIONS: Ang II downregulates miR-145 to regulate Dab2 and Wnt3a/beta-catenin expression in cardiomyocytes under high glucose concentration. Ang II plays a critical role in the regulation of miR-145 in cardiomyocytes under hyperglycaemic conditions. PMID- 29178344 TI - Is the open cystectomy era over? An update on the available evidence. AB - In 2018, robot-assisted radical cystectomy will enter its 15th year. In an era where an effort is being made to standardize complication reporting and videos of the procedure are readily available, it is inevitable and justified that like everything novel, robot-assisted radical cystectomy should be scrutinized against the gold standard, open radical cystectomy. The present comparison is focused on several parameters: oncological, functional and complication outcomes, and direct and indirect costs. Meta-analysis and prospective randomized trials comparing robot-assisted radical cystectomy versus open radical cystectomy have been published, showing an oncological equivalence and in some cases an advantage of robot-assisted radical cystectomy in terms of postoperative morbidity. In the present review, we attempt to update the available knowledge on this debate and discuss the limitations of the current evidence that prevent us from drawing safe conclusions. PMID- 29178343 TI - PRDM14 directly interacts with heat shock proteins HSP90alpha and glucose regulated protein 78. AB - PRDM14 is overexpressed in various cancers and can regulate cancer phenotype under certain conditions. Inhibiting PRDM14 expression in breast and pancreatic cancers has been reported to reduce cancer stem-like phenotypes, which are associated with aggressive tumor properties. Therefore, PRDM14 is considered a promising target for cancer therapy. To develop a pharmaceutical treatment, the mechanism and interacting partners of PRDM14 need to be clarified. Here, we identified the proteins interacting with PRDM14 in triple-negative breast cancer (TNBC) cells, which do not express the three most common types of receptor (estrogen receptors, progesterone receptors, and HER2). We obtained 13 candidates that were pulled down with PRDM14 in TNBC HCC1937 cells and identified them by mass spectrometry. Two candidates-glucose-regulated protein 78 (GRP78) and heat shock protein 90-alpha (HSP90alpha)-were confirmed in immunoprecipitation assay in two TNBC cell lines (HCC1937 and MDA-MB231). Surface plasmon resonance analysis using GST-PRDM14 showed that these two proteins directly interacted with PRDM14 and that the interactions required the C-terminal region of PRDM14, which includes zinc finger motifs. We also confirmed the interactions in living cells by NanoLuc luciferase-based bioluminescence resonance energy transfer (NanoBRET) assay. Moreover, HSP90 inhibitors (17DMAG and HSP990) significantly decreased breast cancer stem-like CD24- CD44+ and side population (SP) cells in HCC1937 cells, but not in PRDM14 knockdown HCC1937 cells. The combination of the GRP78 inhibitor HA15 and PRDM14 knockdown significantly decreased cell proliferation and SP cell number in HCC1937 cells. These results suggest that HSP90alpha and GRP78 interact with PRDM14 and participate in cancer regulation. PMID- 29178345 TI - Proton-Pump Inhibitor use and the risk of Ischaemic Stroke. PMID- 29178346 TI - Highlighting patterns of fungal diversity and composition shaped by ocean currents using the East China Sea as a model. AB - How ocean currents shape fungal transport, dispersal and more broadly fungal biogeography remains poorly understood. The East China Sea (ECS) is a complex and dynamic habitat with different water masses blending microbial communities. The internal transcribed spacer 2 region of fungal rDNA was analysed in water and sediment samples directly collected from the coastal (CWM), Kuroshio (KSWM), Taiwan warm (TWM) and the shelf mixed water mass (MWM), coupled with hydrographic properties measurements, to determine how ocean currents impact the fungal community composition. Almost 9k fungal operational taxonomic units (OTUs) spanning six phyla, 25 known classes, 102 orders and 694 genera were obtained. The typical terrestrial and freshwater fungal genus, Byssochlamys, was dominant in the CWM, while increasing abundance of a specific OTU affiliated with Aspergillus was revealed from coastal to open ocean water masses (TWM and KSWM). Compared with water samples, sediment harboured an increased diversity with distinct fungal communities. The proximity of the Yangtze and Qiantang estuaries homogenizes the surface water and sediment communities. A significant influence of ocean currents on community structure was found, which is believed to reduce proportionally the variation explained by environmental parameters at the scale of the total water masses. Dissolved oxygen and depth were identified as the major parameters structuring the fungal community. Our results indicate that passive fungal dispersal driven by ocean currents and river run-off, in conjunction with the distinct hydrographic conditions of individual water masses, shapes the fungal community composition and distribution pattern in the ECS. PMID- 29178347 TI - Tissuepatch is biocompatible and seals iatrogenic membrane defects in a rabbit model. AB - OBJECTIVE: To evaluate novel sealing techniques for their biocompatibility and sealing capacity of iatrogenic fetal membrane defects in a pregnant rabbit model. METHOD: At day 23 of gestation (term = d31), a standardized fetoscopy was performed through a 14G cannula. The resulting fetal membrane defect was closed with condensed collagen, collagen with fibrinogen, Tissuepatch, Duraseal, or a conventional collagen plug (Lyostypt) as reference. At d30, the fetuses were harvested and full thickness fetal membrane samples were analyzed. The study consisted of 2 consecutive parts: (1) biocompatibility testing by fetal survival, apoptosis, and infiltration of polymorphonuclear cells in the membranes and (2) the efficacy to seal fetal membrane defects. RESULTS: Three sealants (collagen with fibrinogen, Duraseal, or Lyostypt) were associated with a higher fetal mortality compared to control unmanipulated littermates and hence were excluded from further analysis. Tissuepatch was biocompatible, and amniotic fluid levels were comparable to those of control untouched littermates. Compared to the condensed collagen, Tissuepatch was also easier in surgical handling and induced limited cell proliferation. CONCLUSION: Tissuepatch had the best biocompatibility and efficacy in sealing an iatrogenic fetal membrane defect in the pregnant rabbit compared to other readily available sealants. PMID- 29178348 TI - Investigations into in situ Enterococcus faecalis biofilm removal by passive and active sodium hypochlorite irrigation delivered into the lateral canal of a simulated root canal model. AB - AIM: To investigate in situ Enterococcus faecalis biofilm removal from the lateral canal of a simulated root canal system using passive or active irrigation protocols. METHODOLOGY: Root canal models (n = 43) were manufactured from transparent resin materials using 3D printing. Each canal was created with an 18 mm length, apical size 30, a .06 taper and a lateral canal of 3 mm length, with 0.3 mm diameter. Biofilms were grown in the lateral canal and apical 3 mm of the main canal for 10 days. Three models from each group were examined for residual biofilm using SEM. The other forty models were divided into four groups (n = 10). The models were observed under a fluorescence microscope. Following 60 s of 9 mL of 2.5% NaOCl irrigation using syringe and needle, the irrigant was either left stagnant in the canal or activated using gutta-percha, sonic or ultrasonic methods for 30 s. Images were then captured every second using an external camera. The residual biofilm percentages were measured using image analysis software. The data were analysed using generalized linear mixed models. A significance level of 0.05 was used throughout. RESULTS: The greatest level of biofilm removal was obtained with ultrasonic agitation (66.76%) followed by sonic (45.49%), manual agitation (43.97%) and passive irrigation groups (38.67%), respectively. The differences were significant between the residual biofilm in the passive irrigation and both sonic and ultrasonic groups (P = 0.001). CONCLUSION: Agitation resulted in better penetration of 2.5% NaOCl into the lateral canal of an artificial root canal model. Ultrasonic agitation of NaOCl improved the removal of biofilm. PMID- 29178349 TI - Effect of body mass index on the incidence of perineal trauma. AB - OBJECTIVE: To investigate the association between perineal trauma at childbirth and maternal body mass index (BMI), and estimate the risk of perineal trauma among different BMI groups. METHODS: Data were retrospectively assessed from all vaginal deliveries in a UK tertiary maternity unit between 1999 and 2014. Associations between BMI at booking and first- and second-degree tears (minor perineal trauma), third- and fourth-degree tears (obstetric anal sphincter injuries [OASIS]), and frequency of instrumental deliveries were assessed. Multivariate logistic regression included the factors BMI (weight in kilograms divided by the square of height in meters), age, ethnicity, smoking, parity, pregnancy length, episiotomies, instrumental delivery, and birth weight. RESULTS: Data from 45 557 deliveries were used. Compared with women with a normal BMI (<25), odds of minor perineal trauma were significantly reduced among women with obesity (BMI 30 to <35; odds ratio [OR] 0.91, 95% confidence interval [CI] 0.84 0.99) or severe obesity (BMI >=35; OR 0.87, 95% CI 0.77-0.98). OASIS was not significantly associated with BMI. Instrumental delivery rates were higher among women with normal BMI (5936/27 107; 22.0%) than among those with severe obesity (284/2032; 14.0%). CONCLUSION: Increased BMI at booking was associated with a reduced incidence of minor perineal trauma at delivery, but was not associated with OASIS.

AB - BACKGROUND AND AIMS: Inappropriate drug prescribing has increased especially in developing countries where systems for monitoring medicine use are not well developed. This increases the rate of antimicrobial resistance. The study aim was to assess the prescribing patterns among urban primary health facilities in Botswana to provide future guidance including developing future quality indicators. METHODS: Retrospective data from patients' records between January and December 2013 in 19 clinics were collected in a cross-sectional study. The WHO/International Network for Rational Use of Drugs indicators were used to assess prescribing patterns in the study clinics. RESULTS: Average number of drugs per prescription was 2.8; 78.6% of the prescribed antibiotics were by International Non-proprietary Name and 96.1% complied with the Botswana Essential Drugs List. Overall rate of antibiotic prescribing was high (42.7%) with 14.7%, 5.9% and 1.3% of prescriptions having two, three and four antibiotics, respectively. Systemic antibiotics (JO1C) accounted for 45.4% of prescribed antibiotics of which amoxicillin accounted for 28.4% and metronidazole 14.4% of all antibiotic prescriptions. There was low use of co-amoxiclav (0.3% of all antibiotic prescriptions). Third generation cephalosporins and macrolides accounted for 9.8% and 6.2% of antibiotic prescriptions respectively, with no prescribing of fluoroquinolones. The majority of indications (87%) for antibiotic prescriptions were according to ICD classification. CONCLUSIONS: While most indications for antibiotic prescriptions were based on signs and symptoms according to ICD, antibiotic prescribing rates were high with some conditions not requiring antibiotics because they are viral infections. There is a need to further improve prescribing practices through induction and training of in service prescribers. An effective management tool for monitoring antibiotic prescribing practices at Primary Health Care facilities should be designed and implemented, including developing robust quality indicators.

AB - Source-semiconductor-drain coplanar transistors with an organic semiconductor layer located within the same plane of source/drain electrodes are attractive for next-generation electronics, because they could be used to reduce material consumption, minimize parasitic leakage current, avoid cross-talk among different devices, and simplify the fabrication process of circuits. Here, a one-step, drop casting-like printing method to realize a coplanar transistor using a model semiconductor/insulator [poly(3-hexylthiophene) (P3HT)/polystyrene (PS)] blend is developed. By manipulating the solution dewetting dynamics on the metal electrode and SiO2 dielectric, the solution within the channel region is selectively confined, and thus make the top surface of source/drain electrodes completely free of polymers. Subsequently, during solvent evaporation, vertical phase separation between P3HT and PS leads to a semiconductor-insulator bilayer structure, contributing to an improved transistor performance. Moreover, this coplanar transistor with semiconductor-insulator bilayer structure is an ideal system for injecting charges into the insulator via gate-stress, and the thus formed PS electret layer acts as a "nonuniform floating gate" to tune the threshold voltage and effective mobility of the transistors. Effective field effect mobility higher than 1 cm2 V-1 s-1 with an on/off ratio > 107 is realized, and the performances are comparable to those of commercial amorphous silicon transistors. This coplanar transistor simplifies the fabrication process of corresponding circuits. PMID- 29178352 TI - Concise Review: The Use of Stem Cells for Understanding and Treating Huntington's Disease. AB - Two decades ago, researchers identified that a CAG expansion mutation in the huntingtin (HTT) gene was involved in the pathogenesis of Huntington's disease (HD). However, since the identification of the HTT gene, there has been no advance in the development of therapeutic strategies to prevent or reduce the progression of HD. With the recent advances in stem cell biology and human cell reprogramming technologies, several novel and exciting pathways have emerged allowing researchers to enhance their understanding of the pathogenesis of HD, to identify and screen potential drug targets, and to explore alternative donor cell sources for cell replacement therapy. This review will discuss the role of compensatory neurogenesis in the HD brain, the use of stem cell-based therapies for HD to replace or prevent cell loss, and the recent advance of cell reprogramming to model and/or treat HD. These new technologies, coupled with advances in genome editing herald a promising new era for HD research with the potential to identify a therapeutic strategy to alleviate this debilitating disorder.

AB - AIMS: Early identification of patients with febrile neutropenia (FN) is desirable for initiation of preventive treatment, such as with antibiotics. In this study, the time courses of two inflammation biomarkers, interleukin (IL)-6 and C reactive protein (CRP), following adjuvant chemotherapy of breast cancer, were characterized. The potential to predict development of FN by IL-6 and CRP, and other model-derived and clinical variables, was explored. METHODS: The IL-6 and CRP time courses in cycles 1 and 4 of breast cancer treatment were described by turnover models where the probability for an elevated production following initiation of chemotherapy was estimated. Parametric time-to-event models were developed to describe FN occurrence to assess: (i) predictors available before chemotherapy is initiated; (ii) predictors available before FN occurs; and (iii) predictors available when FN occurs. RESULTS: The IL-6 and CRP time courses were successfully characterized with peak IL-6 typically occurring 2 days prior to CRP peak. Of all evaluated variables the CRP time course was most closely associated with the occurrence of FN. Since the CRP peak typically occurred at the time of FN diagnosis it will, however, have limited value for identifying the need for preventive treatment. The time course of IL-6 was the predictor that could best forecast FN events. Of the variables available at baseline, age was the best, although in comparison a relatively weak, predictor. CONCLUSIONS: The developed models add quantitative knowledge about IL-6 and CRP and their relationship to the development of FN. The study suggests that IL-6 may have potential as a clinical predictor of FN if monitored during myelosuppressive chemotherapy.

AB - The oxygen evolution reaction (OER) is involved in various renewable energy systems, such as water-splitting cells and metal-air batteries. Ni-Fe layered double hydroxides (LDHs) have been reported as promising OER electrocatalysts in alkaline electrolytes. The rational design of advanced nanostructures for Ni-Fe LDHs is highly desirable to optimize their electrocatalytic performance. Herein, we report a facile self-templated strategy for the synthesis of novel hierarchical hollow nanoprisms composed of ultrathin Ni-Fe LDH nanosheets. Tetragonal nanoprisms of nickel precursors were first synthesized as the self sacrificing template. Afterwards, these Ni precursors were consumed during the hydrolysis of iron(II) sulfate for the simultaneous growth of a layer of Ni-Fe LDH nanosheets on the surface. The resultant Ni-Fe LDH hollow prisms with large surface areas manifest high electrocatalytic activity towards the OER with low overpotential, small Tafel slope, and remarkable stability. PMID- 29178354 TI - Hyperexcitability of the network contributes to synchronization processes in the human epileptic neocortex. AB - KEY POINTS: Hyperexcitability and hypersynchrony of neuronal networks are thought to be linked to the generation of epileptic activity in both humans and animal models. Here we show that human epileptic postoperative neocortical tissue is able to generate two different types of synchronies in vitro. Epileptiform bursts occurred only in slices derived from epileptic patients and were hypersynchronous events characterized by high levels of excitability. Spontaneous population activity emerged in both epileptic and non-epileptic tissue, with a significantly lower degree of excitability and synchrony, and could not be linked to epilepsy. These results help us to understand better the role of excitatory and inhibitory neuronal circuits in the generation of population events, and to define the subtle border between physiological and pathological synchronies. ABSTRACT: Interictal activity is a hallmark of epilepsy diagnostics and is linked to neuronal hypersynchrony. Little is known about perturbations in human epileptic neocortical microcircuits, and their role in generating pathological synchronies. To explore hyperexcitability of the human epileptic network, and its contribution to convulsive activity, we investigated an in vitro model of synchronous burst activity spontaneously occurring in postoperative tissue slices derived from patients with or without preoperative clinical and electrographic manifestations of epileptic activity. Human neocortical slices generated two types of synchronies. Interictal-like discharges (classified as epileptiform events) emerged only in epileptic samples, and were hypersynchronous bursts characterized by considerably elevated levels of excitation. Synchronous population activity was initiated in both epileptic and non-epileptic tissue, with a significantly lower degree of excitability and synchrony, and could not be linked to epilepsy. However, in pharmacoresistant epileptic tissue, a higher percentage of slices exhibited population activity, with higher local field potential gradient amplitudes. More intracellularly recorded neurons received depolarizing synaptic potentials, discharging more reliably during the events. Light and electron microscopic examinations showed slightly lower neuron densities and higher densities of excitatory synapses in the human epileptic neocortex. Our data suggest that human neocortical microcircuits retain their functionality and plasticity in vitro, and can generate two significantly different synchronies. We propose that population bursts might not be pathological events while interictal like discharges may reflect the epileptogenicity of the human cortex. Our results show that hyperexcitability characterizes the human epileptic neocortical network, and that it is closely related to the emergence of synchronies.

AB - Existing evidence indicates the importance of observing correct, normal actions on the motor cortical activities. However, the exact neurophysiological mechanisms, particularly in the somatosensory system, remain unclear. This study aimed to elucidate the effects of observing normal and abnormal hand movements on the contralateral primary somatosensory (cSI), contralateral (cSII) and ipsilateral (iSII) secondary somatosensory activities. Experiment I was designed to investigate the effects of motor outputs on the somatosensory processing, in which subjects were instructed to relax or manipulate a small cube. Experiment II was tailored to examine the somatosensory responses to the observation of normal (Normal) and abnormal (Abnormal) hand movements. The subjects received electrical stimulation to right median nerve and magnetoencephalography (MEG) recordings during the whole experimental period. Regional cortical activation and functional connectivity were analyzed. Compared to the resting condition, a reduction in cSI and an enhancement of SII activation was found when subjects manipulated a cube, suggesting the motor outputs have an influence on the somatosensory responses. Further investigation of the effects of observing different hand movements showed that cSII activity was significantly stronger in the Normal than Abnormal condition. Moreover, compared with Abnormal condition, a higher cortical coherence of cSI-iSII at theta bands and cSII-iSII at beta bands was found in Normal condition. Conclusively, the present results suggest stronger activation and enhanced functional connectivity within the somatosensory system during the observation of normal than abnormal hand movements. These findings also highlight the importance of viewing normal, correct hands movements in the stroke rehabilitation.

AB - A silica-based reversed-phase stationary phase bonding with phenyl and tetrazole groups was synthesized by thiol-epoxy ring opening reaction. The bonded groups could not only provide hydrophobic interaction, but also pi-pi, hydrogen bonding, electrostatic interactions, and so on. The results of characterization with elemental analysis and solid-state 13 C cross-polarization magic-angle-spinning NMR spectroscopy indicated the successful preparation of phenyl/tetrazole sulfoether bonded stationary phase. Chromatographic evaluation revealed that phenyl/tetrazole sulfoether bonded stationary phase behaved well under the reversed-phase mode. The column parameters (H, S*, A, B, and C) showed different selectivity compared with some typical commercial columns, and it was validated by the separation of estrogen, ginsenoside, alkaloid samples. Based on the different selectivity between phenyl/tetrazole sulfoether bonded stationary phase and C18 columns, phenyl/tetrazole sulfoether bonded stationary phase also showed potential to construct a 2D reversed-phase liquid chromatography system with C18. And it was verified by the separation of corydalis tuber and curcuma zedoary extracts. PMID- 29178358 TI - Conventional-SCS vs. Burst-SCS and the Behavioral Effect on Mechanical Hypersensitivity in a Rat Model of Chronic Neuropathic Pain: Effect of Amplitude. AB - OBJECTIVE: Various spinal cord stimulation (SCS) modes are used in the treatment of chronic neuropathic pain disorders. Conventional (Con) and Burst-SCS are hypothesized to exert analgesic effects through different stimulation-induced mechanisms. Preclinical electrophysiological findings suggest that stimulation intensity is correlated with the effectiveness of Burst-SCS. Therefore, we aimed to investigate the relation between amplitude (charge per second) and behavioral effects in a rat model of chronic neuropathic pain, for both Conventional Spinal Cord Stimulation (Con-SCS) and biphasic Burst-SCS. MATERIALS AND METHODS: Animals (n = 12 rats) received a unilateral partial sciatic nerve ligation, after which they were implanted with quadripolar electrodes in the epidural space at thoracic level 13. Mechanical hypersensitivity was assessed using paw withdrawal thresholds (WTs) to von Frey monofilaments, at various SCS intensities (amplitudes) and multiple time points during 60 minutes of stimulation and 30 minutes post stimulation. RESULTS: Increasing amplitude was shown to improve the efficacy of Con-SCS, whereas the efficacy of Burst-SCS showed a non-monotonic relation with amplitude. Con-SCS at 66% MT (n = 5) and Burst-SCS at 50% MT (n = 6) were found to be equally effective in normalizing mechanical hypersensitivity. However, in the assessed time period Burst-SCS required significantly more mean charge per second to do so (p < 0.01). When applied at comparable mean charge per second, Con-SCS resulted in a superior behavioral outcome (p < 0.01), compared with Burst-SCS. CONCLUSION: Biphasic Burst-SCS requires significantly more mean charge per second in order to achieve similar pain relief, as compared with Con SCS, in an experimental model of chronic neuropathic pain.

AB - Construction of multifactorial disease models from epidemiological findings and their application to disease pedigrees for risk prediction is nontrivial for all but the simplest of cases. Multifactorial Disease Risk Calculator is a web tool facilitating this. It provides a user-friendly interface, extending a reported methodology based on a liability-threshold model. Multifactorial disease models incorporating all the following features in combination are handled: quantitative risk factors (including polygenic scores), categorical risk factors (including major genetic risk loci), stratified age of onset curves, and the partition of the population variance in disease liability into genetic, shared, and unique environment effects. It allows the application of such models to disease pedigrees. Pedigree-related outputs are (i) individual disease risk for pedigree members, (ii) n year risk for unaffected pedigree members, and (iii) the disease pedigree's joint liability distribution. Risk prediction for each pedigree member is based on using the constructed disease model to appropriately weigh evidence on disease risk available from personal attributes and family history. Evidence is used to construct the disease pedigree's joint liability distribution. From this, lifetime and n year risk can be predicted. Example disease models and pedigrees are provided at the website and are used in accompanying tutorials to illustrate the features available. The website is built on an R package which provides the functionality for pedigree validation, disease model construction, and risk prediction. Website: http://grass.cgs.hku.hk:3838/mdrc/current. PMID- 29178359 TI - Elevated luteinizing hormone despite normal testosterone levels in older men natural history, risk factors and clinical features. AB - OBJECTIVE: Elevated luteinizing hormone (LH) with normal testosterone (T) suggests compensated dysregulation of the gonadal axis. We describe the natural history, risk factors and clinical parameters associated with the development of high LH (HLH, LH >9.4 U/L) in ageing men with normal T (T >= 10.5 nmol/L). DESIGN, PATIENTS AND MEASUREMENTS: We conducted a 4.3-year prospective observational study of 3369 community-dwelling European men aged 40-79 years. Participants were classified as follows: incident (i) HLH (n = 101, 5.2%); persistent (p) HLH (n = 128, 6.6%); reverted (r) HLH (n = 46, 2.4%); or persistent normal LH (pNLH, n = 1667, 85.8%). Potential predictors and changes in clinical features associated with iHLH and rHLH were analysed using regression models. RESULTS: Age >70 years (OR = 4.12 [2.07-8.20]), diabetes (OR = 2.86 [1.42 5.77]), chronic pain (OR = 2.53 [1.34-4.77]), predegree education (OR = 1.79 [1.01-3.20]) and low physical activity (PASE <= 78, OR = 2.37 [1.24-4.50]) predicted development of HLH. Younger age (40-49 years, OR = 8.14 [1.35-49.13]) and nonsmoking (OR = 5.39 [1.48-19.65]) predicted recovery from HLH. Men with iHLH developed erectile dysfunction, poor health, cardiovascular disease (CVD) and cancer more frequently than pNLH men. In pHLH men, comorbidities, including CVD, developed more frequently, and cognitive and physical function deteriorated more, than in pNLH men. Men with HLH developed primary hypogonadism more frequently (OR = 15.97 [5.85-43.60]) than NLH men. Men with rHLH experienced a small rise in BMI. CONCLUSIONS: Elevation of LH with normal T is predicted by multiple factors, reverts frequently and is not associated with unequivocal evidence of androgen deficiency. High LH is a biomarker for deteriorating health in aged men who tend to develop primary hypogonadism.

AB - Blinatumomab, a bi-specific T-cell engaging CD3-CD19 antibody construct, has shown significant activity in patients with relapsed/refractory (R/R) B-cell acute lymphoblastic leukemia (ALL). Despite this improvement, most patients relapse. Here, we describe the outcome of 68 patients with R/R ALL after failure of blinatumomab therapy: 38 (56%) blinatumomab refractory; 30 (44%) relapsing after initial response. After a median follow-up of 49 months, 9 (13%) patients remained alive. The median overall survival after blinatumomab failure was 5.2 months. At the time of failure, among 61 patients evaluated for immunophenotype, 56 (92%) had CD19-positive blasts; only five (8%) had ALL recurrence with CD19 negative disease. Two patients progressed with lower CD19 expression. In summary, the outcome of patients with R/R ALL after blinatumomab failure is poor and treatment of these patients remains an unmet medical need. Our findings indicate that blinatumomab therapy would not exclude a significant number of patients from the potential benefit of subsequent CD19-directed therapies such as chimeric antigen receptor T-cell therapy. PMID- 29178362 TI - The relationship between 18 F-FDG-PETCT-derived markers of tumour metabolism and systemic inflammation in patients with recurrent disease following surgery for colorectal cancer. AB - AIM: 18 F-fluorodeoxyglucose positron emission tomography-computed tomography (18 F-FDG-PETCT)-derived markers of tumour metabolism have been reported to have prognostic significance in a variety of tumours. Host inflammation is also recognized to have prognostic significance. The aim of the present study was to investigate the relationship between these markers and host systemic inflammation in patients undergoing elective surgery for colorectal cancer. METHOD: Patients with histologically confirmed colorectal cancer who underwent elective surgery between 2008 and 2015 and also underwent 18 F-FDG-PETCT at a single centre were included (n = 103). The neutrophil-lymphocyte ratio (NLR) and modified Glasgow Prognostic Score (mGPS) were derived from routine blood tests. The maximum standardized uptake (SUVmax), peak standardized uptake (SUVpeak), metabolic tumour volume (MTV) and total lesion glycolysis (TLG) were measured. RESULTS: There was no association between 18 F-FDG-PETCT measures of tumour metabolism and systemic inflammation in the 33 patients who underwent preoperative imaging. Of the 70 patients with recurrent disease who underwent 18 F-FDG-PETCT during follow up, patients with NLR >= 5 had a significantly higher SUVmax (20 vs 7, P = 0.002), SUVpeak (14 vs 5, P < 0.001), MTV (29 g vs 2 g, P = 0.001) and TLG (338 g vs 9 g, P < 0.001). Similarly, patients with a mGPS of 1-2 at the time of 18 F FDG-PETCT had a significantly higher median SUVmax (11 vs 6, P = 0.048), SUVpeak (8 vs 4, P = 0.046), MTV (13 ml vs 2 ml, P = 0.005) and TLG (146 g vs 10 g, P = 0.004). CONCLUSION: The present study reports a direct association between 18 F FDG-PETCT-derived measures of tumour metabolism and systemic inflammation in patients with recurrent colorectal cancer. PMID- 29178363 TI - Interventions to promote healthy eating choices when dining out: A systematic review of reviews. AB - PURPOSE: To synthesize review research pertaining to the effectiveness of interventions in dining-out settings to reduce food/calorie consumption. METHODS: A rapid review methodology was employed to focus on synthesized research. A comprehensive search for peer-reviewed systematic reviews from 2010 to 2015 yielded 1,847 citations. Following screening, ten systematic reviews were included. RESULTS: The 10 included systematic reviews identified 183 primary studies evaluating evidence in three behavioural intervention areas: social models/norms, manipulation of size, and provision of health information. Three systematic reviews evaluating the use of social models/norms found this was an effective intervention for influencing food intake. Five systematic reviews that assessed manipulation of portion/dishware/cutlery size found a small-to-moderate effect on food consumption. Three systematic reviews looked at the provision of health information, which was not effective alone; however, in combination with contextual or interpretive material such as traffic lights or exercise equivalence, this was shown to reduce calorie consumption. One systematic review covered two topic areas. CONCLUSIONS: The results indicate that policies or interventions that aim to improve healthy choices or consumption when dining out would benefit from harnessing social norms and positive positioning of social identity. Furthermore, provision of health information should always be accompanied by an interpretative guide, such as traffic lights. Manipulation of plate/portion/cutlery size may be effective; however, the effect size is small and further research is required to investigate whether this effect is retained in overweight or obese populations. Statement of contribution What is already known on this subject? Eating behaviours (food choices, consumption) have played a role in the obesity epidemic. Behavioural 'nudges' have tried to increase healthier eating choices. What does this study add? Social norms and modelling have a strong influence in both directions on how much people consume. Provision of nutritional information needs to be paired with interpretative aids (e.g., traffic lights). Manipulation of portion size is less effective in overweight populations. PMID- 29178364 TI - Fine-needle aspiration cytology for parotid lesions, can we avoid surgery? AB - OBJECTIVE: Salivary gland neoplasms are rare tumours, with most arising in the parotid gland. Fine-needle aspiration cytology (FNAC) is a common method for preoperative evaluation of parotid masses, although its usefulness is controversial. This study was designed to evaluate the accuracy of FNAC in a large cohort of patients, with emphasis on diagnosis of benign tumours and especially Warthin tumour which can be managed conservatively. STUDY DESIGN: Retrospective case series with chart review. SETTING: Tertiary medical centre. SUBJECTS AND METHODS: From 1991 to 2014, all patients 18 or older with both preoperative FNAC and postoperative pathology report were included. Patients with a history of head and neck malignancy or chronic sialoadenitis and patients who had undergone prior oncological treatment were excluded. RESULTS: 470 patients were available for analysis. Overall accuracy was 82.6%. Positive predictive value (PPV) varied between 88.6% and 94.3% for pleomorphic adenoma and 77.1%-100% for Warthin tumour, with values varying depending on different characteristics of patients (eg age, smoking status). For pathologically proven malignant tumours, the FNAC diagnosis was benign or non-diagnostic in 26% of the cases. CONCLUSION: Fine-needle aspiration cytology has limited utility in confirming a benign diagnosis of a parotid mass for most patients, although for some subpopulations, the PPV may be high enough to defer surgery. PMID- 29178365 TI - Levodopa: A new look at an old friend. AB - Levodopa is the most effective antiparkinsonian agent, but chronic treatment is associated with the development of motor complications in the majority of patients with PD. Recent scientific and clinical advances are improving this situation. Long-term, double-blind studies demonstrate that dose is an important risk factor for the development of both motor fluctuations and dyskinesia, and suggest that it is best to use low doses of l-dopa when possible. Inhaled l-dopa and sublingual apomorphine are now being developed as rescue therapies that permit rapid and predictable reversal of off periods. Finally, substantial evidence suggests that motor complications are related to the nonphysiological restoration of brain dopamine with intermittent oral doses of standard l-dopa. Double-blind studies demonstrate significant clinical benefits with continuous intraintestinal infusion of l-dopa. New approaches that provide continuous plasma l-dopa levels without the need for a surgical procedure are currently being investigated. Finally, the development of an oral long-acting form of l-dopa that provides continuous plasma l-dopa levels is actively being pursued. Collectively, these approaches offer the potential to considerably reduce and even prevent the disability associated with l-dopa-induced motor complications.

PMID- 29178366 TI - Do we overestimate left ventricular ejection fraction by two-dimensional echocardiography in patients with left bundle branch block? AB - AIMS: Left bundle branch block (LBBB) causes a dyssynchronized contraction of left ventricle. This is a kind of regional wall-motion abnormality and measuring left ventricular ejection fraction (LVEF) by two-dimensional (2D) echocardiography could be less reliable in this particular condition. Our aim was to evaluate the role of dyssynchrony index (SDI), measured by three-dimensional (3D) echocardiography, in assessment of LVEF and left ventricular volumes accurately in patients with LBBB. METHODS AND RESULTS: In this case-control study, we included 52 of 64 enrolled participants (twelve participants with poor image quality were excluded) with LBBB and normal LVEF or nonischemic cardiomyopathy. Left ventricular ejection fraction (LVEF) and left ventricular volumes were assessed by 2D (modified Simpson's rule) and 3D (four beats full volume analysis) echocardiography and the impact of SDI on results were evaluated. In patients with SDI >=6%, LVEF measurements were significantly different (46.00% [29.50-52.50] vs 37.60% [24.70-45.15], P < .001) between 2D and 3D echocardiography, respectively. In patients with SDI < 6%, there were no significant differences between two modalities in terms of LVEF measurements (54.50% [49.00-59.00] vs 54.25% [40.00-58.25], P = .193). LV diastolic volumes were not significantly different while systolic volumes were underestimated by 2D echocardiography, and this finding was more pronounced when SDI >= 6%. CONCLUSION: In patients with LBBB and high SDI (>=6%), LVEF values were overestimated and systolic volumes were underestimated by 2D echocardiography compared to 3D echocardiography. PMID- 29178367 TI - Estimation of discrete survival function for error-prone diagnostic tests. AB - The product limit or Kaplan-Meier (KM) estimator is commonly used to estimate the survival function in the presence of incomplete time to event. Application of this method assumes inherently that the occurrence of an event is known with certainty. However, the clinical diagnosis of an event is often subject to misclassification due to assay error or adjudication error, by which the event is assessed with some uncertainty. In the presence of such errors, the true distribution of the time to first event would not be estimated accurately using the KM method. We develop a method to estimate the true survival distribution by incorporating negative predictive values and positive predictive values, into a KM-like method of estimation. This allows us to quantify the bias in the KM survival estimates due to the presence of misclassified events in the observed data. We present an unbiased estimator of the true survival function and its variance. Asymptotic properties of the proposed estimators are provided, and these properties are examined through simulations. We demonstrate our methods using data from the Viral Resistance to Antiviral Therapy of Hepatitis C study.

AB - A specific, sensitive and stable high-performance liquid chromatography (HPLC) based analytical method was established to determine the level of pefloxacin mesylate (PM) in the plasma and various tissues of chickens. Chickens were randomly assigned to 12 equal experiment groups, including 11 treatment groups and one control group. The chickens in the treatment groups received oral administration of PM and were sacrificed at different pre-determined time points, with their blood and various organs harvested, extracted and analyzed by HPLC to quantify the level of the residual antibiotic. Method validation studies indicated that the HPLC measurement showed excellent precision, reproducibility, stability and robustness. The obtained pharmacokinetic parameters suggested that PM reached peak levels in various tissues within 1-2 h after its oral administration, and was mainly concentrated in liver and kidney. The antibiotic was also found to be cleared from chicken crureus, brain, testes, ovaries and pancreas at higher rates compared with other organs. Overall, the rapid accumulation of PM could at least be partially attributed to its relatively slow organ clearance. These results could serve as a useful guidance for the rational use of PM and other quinolone-derived antimicrobials in the treatment of infectious diseases in chickens and other animals. PMID- 29178370 TI - Use and perceptions of plastination among medical anatomy educators in the United States. AB - Traditionally, medical schools have maintained collections of tissues/organs to engage students in anatomy. Such collections are often stored in volatile and toxic preservatives. Plastination is an alternative tissue preservation technique in which polymers replace water and lipids resulting in benign, dry, and anatomically authentic specimens. Plastination is used in medical education internationally; however, its use within U.S. medical schools is not widely discussed in the anatomical literature. This study aimed to determine the knowledge, use, and perceptions of plastination as a teaching tool among U.S. anatomy medical educators. A total of 98 medical anatomy educators who fit inclusion criteria and teach allopathic (MD) students and/or osteopathic (DO) students in the United States completed a national survey, representing 77 medical schools across 37 states. Of these, 100% had heard of plastination, 57% correctly defined plastination, but only 39% currently utilize plastinates for anatomy education. The most frequent explanation for nonuse of plastinates was a preference for the dissection experience, followed by lack of resources and negative past experiences related to durability and quality. A majority (75%) of U.S. medical anatomy educators perceived plastination as a good supplement to, but not a replacement for, cadaveric dissection, 19% indicated no curiosity to use plastination or considered it not useful, and 14% expressed ethical concerns. These findings suggest plastinates are more widely used in the United States than reflected by the literature; however, perceptions regarding their utility indicate a dominant theme for their use to supplement, not replace, cadaveric dissection.

AB - BACKGROUND: Overdose of insulin often causes long-lasting severe hypoglycaemia. Insulin degludec has the longest duration of action among the available insulin products; thus, an overdose of insulin degludec can lead to long-lasting hypoglycaemia. In the present paper, we report the case of a woman with long lasting hypoglycaemia attributable to insulin degludec overdose and markedly prolonged insulin degludec half-life. CASE REPORT: A 64-year-old woman with Type 2 diabetes receiving insulin therapy was taken to an emergency department because of disturbed consciousness 21 h after self-injection of 300 units of insulin degludec (4.34 units/kg). Her plasma glucose level was 2.3 mmol/l. She received repeated intravenous boluses of dextrose for 43 h with continuous intravenous dextrose infusion, but no improvement in long-lasting hypoglycaemia or consciousness was observed. Considering the possibility of adrenal insufficiency, intravenous dexamethasone was administered, and her plasma glucose levels subsequently remained above 5.5 mmol/l without intravenous dextrose boluses. She gradually regained consciousness. A total of 34 h after the overdose, her plasma immunoreactive insulin levels were markedly increased and then gradually declined over ~400 h. The insulin degludec half-life was 40.76 h. CONCLUSION: Although the reported half-life of insulin degludec in the body is ~25 h when administered in standard doses (0.4-0.8 units/kg), no study has investigated its half-life after overdose. In the present case, the half-life of insulin degludec was ~1.6 times longer than that observed with standard doses, probably leading to long-lasting hypoglycaemia. Physicians should be aware of the possibility of unexpected long lasting severe hypoglycaemia resulting from insulin degludec overdose. PMID- 29178372 TI - THC alters alters morphology of neurons in medial prefrontal cortex, orbital prefrontal cortex, and nucleus accumbens and alters the ability of later experience to promote structural plasticity. AB - Psychoactive drugs have the ability to alter the morphology of neuronal dendrites and spines and to influence later experience-dependent structural plasticity. If rats are given repeated injections of psychomotor stimulants (amphetamine, cocaine, nicotine) prior to being placed in complex environments, the drug experience interferes with the ability of the environment to increase dendritic arborization and spine density. Repeated exposure to Delta 9-Tetrahydrocannabinol (THC) changes the morphology of dendrites in medial prefrontal cortex (mPFC) and nucleus accumbens (NAcc). To determine if drugs other than psychomotor stimulants will also interfere with later experience-dependent structural plasticity we gave Long-Evans rats THC (0.5 mg/kg) or saline for 11 days before placing them in complex environments or standard laboratory caging for 90 days. Brains were subsequently processed for Golgi-Cox staining and analysis of dendritic morphology and spine density mPFC, orbital frontal cortex (OFC), and NAcc. THC altered both dendritic arborization and spine density in all three regions, and, like psychomotor stimulants, THC influenced the effect of later experience in complex environments to shape the structure of neurons in these three regions. We conclude that THC may therefore contribute to persistent behavioral and cognitive deficits associated with prolonged use of the drug.

AB - The geographic impact on the quality of Alismatis Rhizoma (derived from the tuber of Alisma orientale), a reputable diuretic traditional Chinese medicine, has seldom been evaluated. Here a metabolomics-driven approach targeting the bioactive protostane triterpenes was developed, by incorporating UHPLC with quadrupole time-of-flight mass spectrometry-based untargeted metabolite profiling and multiple reaction monitoring quantitative assay, to probe the triterpene differences between Alismatis Rhizoma samples collected from Sichuan, Fujian, and Jiangxi Provinces. Following the metabolomics workflows, the samples from Sichuan and Jiangxi displayed distinct differences in their triterpene profiles, whereas those from Fujian showed remarkable intra-class variation. Twenty-three triterpenes were identified to contribute most to the differentiated clustering. A sensitive, precise, repeatable, and accurate quantitative assay method was established on a hybrid triple quadrupole-linear ion trap mass spectrometer to quantify the contents of eight triterpene compounds. Taking into account the metabolomics and quantitation results, alisol B 23-acetate and alisol A are significantly different in Alismatis Rhizoma from Sichuan and Jiangxi Provinces, and they may have the potential for geographic discrimination. These results illustrate how geographic difference impacts the triterpene chemistry of Alismatis Rhizoma. Metabolomics-driven chemical comparison is suitable for the quality evaluation of traditional Chinese medicine.

PMID- 29178374 TI - Differential adult survival at close seabird colonies: The importance of spatial foraging segregation and bycatch risk during the breeding season. AB - Marine megafauna, including seabirds, are critically affected by fisheries bycatch. However, bycatch risk may differ on temporal and spatial scales due to the uneven distribution and effort of fleets operating different fishing gear, and to focal species distribution and foraging behavior. Scopoli's shearwater Calonectris diomedea is a long-lived seabird that experiences high bycatch rates in longline fisheries and strong population-level impacts due to this type of anthropogenic mortality. Analyzing a long-term dataset on individual monitoring, we compared adult survival (by means of multi-event capture-recapture models) among three close predator-free Mediterranean colonies of the species. Unexpectedly for a long-lived organism, adult survival varied among colonies. We explored potential causes of this differential survival by (1) measuring egg volume as a proxy of food availability and parental condition; (2) building a specific longline bycatch risk map for the species; and (3) assessing the distribution patterns of breeding birds from the three study colonies via GPS tracking. Egg volume was very similar between colonies over time, suggesting that environmental variability related to habitat foraging suitability was not the main cause of differential survival. On the other hand, differences in foraging movements among individuals from the three colonies expose them to differential mortality risk, which likely influenced the observed differences in adult survival. The overlap of information obtained by the generation of specific bycatch risk maps, the quantification of population demographic parameters, and the foraging spatial analysis should inform managers about differential sensitivity to the anthropogenic impact at mesoscale level and guide decisions depending on the spatial configuration of local populations. The approach would apply and should be considered in any species where foraging distribution is colony-specific and mortality risk varies spatially. PMID- 29178376 TI - A comparative meta-analysis on the relationship of faecal calcium and phosphorus excretion in mammals. AB - To investigate the relationship between faecal calcium (Ca) and phosphorus (P) excretion in different mammalian species, a meta-analysis on digestibility data derived from the literature was conducted. Seventy-three studies on carnivores, omnivores, large and small hindgut fermenters, ruminants and hippos (a total of 21 mammalian species, precondition for inclusion dietary Ca/P ratio 1.5/1 - 3.0/1) were analysed for Ca and P digestibility. Dietary Ca/P ratios were lower than faecal Ca/P ratios in carnivores, omnivores, ruminants and hippos. In hindgut fermenters, dietary Ca/P ratios were higher than faecal Ca/P ratios, indicating higher intestinal Ca absorption in these species. In all species investigated, there was a significant positive relationship between Ca intake and faecal Ca excretion and between P intake and faecal P excretion. In the biologically relevant range, these equations predicted lower faecal Ca losses in hindgut fermenters than ruminants, for faecal P vice versa. In all species, faecal Ca and P excretion correlated significantly. In carnivores, this highly linear correlation was exceptionally strong (R2 = .92). Yet, the linearity of the correlation was questionable in omnivores and ruminants. Possibly, the strong linear correlation of faecal Ca and P excretion in carnivores is due to the formation of insoluble Ca/P complexes in their relatively short and simple gastrointestinal tract. Another hypothesis is that in carnivores, Ca homeostasis relies on modifying bone turnover to a higher degree than on changes in intestinal Ca absorption. For the formation of bone matrix, a constant ratio of Ca and P absorption is of advantage. PMID- 29178378 TI - Editorial: Prevalence of Arthritis Revisited. PMID- 29178377 TI - Examination of the World Health Organization Disability Assessment System as a Measure of Disability Severity Among Veterans Receiving Cognitive Processing Therapy. AB - Cognitive processing therapy (CPT) is effective for reducing posttraumatic stress disorder (PTSD) and depression among military veterans. However, studies have not examined whether CPT is associated with reductions in disability severity. The current study examines the association between disability severity and PTSD and depression among U.S. veterans who are receiving CPT. Veterans completed measures at pre- and posttreatment and received CPT through a Veterans Affairs PTSD outpatient (n = 155) or residential (n = 177) program. The World Health Organization Disability Assessment Schedule (WHODAS) 2.0 was used to assess disability severity. The WHODAS 2.0 scores were positively correlated with clinician- and veteran-rated PTSD and veteran-rated depression at pre- and posttreatment (r = .22 to. 60). Compared with outpatients, veterans in residential treatment had worse scores on the WHODAS Mobility scale (etap2 = .03), but on no other WHODAS 2.0 scales. Pre- to posttreatment reductions were found on all WHODAS 2.0 subscales (etap2 = .03 to .15). Reductions in PTSD and depression were positively associated with improvements on the WHODAS 2.0 Summary scale and most subscales (r = .22 to. 52). Findings suggest that the WHODAS 2.0 is a promising disability severity measure for veterans in PTSD treatment. Findings also suggest that CPT may help veterans to achieve reductions in disability severity. PMID- 29178380 TI - Current matters of the heart. PMID- 29178379 TI - Successful treatment of thrombotic microangiopathy associated with dengue infection: A case report and literature review. AB - Dengue infection has been associated with multiple renal complications, including glomerulonephritis, acute tubular necrosis, tubulointerstitial nephritis, and thrombotic microangiopathy (TMA), this last one being a rare complication of dengue, with only a few reported cases. TMA associated with dengue can be explained by an alteration in the activity of the enzyme ADAMTS13, leading to thrombotic thrombocytopenic purpura; or it can be secondary to direct or indirect endothelial injury by the virus, which leads to hemolytic uremic syndrome. Here, we present a case of severe TMA, not related to ADAMTS13, which was clearly associated with dengue infection. PMID- 29178381 TI - A retrospective evaluation of 128 socket-shield cases in the esthetic zone and posterior sites: Partial extraction therapy with up to 4 years follow-up. AB - OBJECTIVES: Tooth loss results in an inevitable alveolar ridge reduction. This has established a cautionary approach to extract, wait, augment, and insert the implant, in lieu of immediate placement. However, saving the tooth or part of it whenever possible is more conservative and supports the vital periodontal tissue buccofacial to an implant. The purpose of this cases series was to report on implant survival using this technique in a large cohort of patients at mid-term follow-up. MATERIALS AND METHODS: A private practice patient database was searched for all patients having received socket-shield treatment in conjunction with immediate implant placement. Of the results returned, 128 met the inclusion criteria of >=12 months from date of restoration, or failing prior to definitive restoration. These patients were recalled for evaluation of the restored implants up to 4 years post-treatment. RESULTS: Seventy immediate implants with socket shields were placed in female patients and 58 in males, age range 24-71 (mean 39 years). The distribution of sites treated were: maxillary incisors (64%), premolars (22%), canines (14%); maxilla (89.9%), mandible (10.1%). 123/128 implants osseointegrated and survived 1-4 years following restoration (survival rate 96.1%). A combined complication rate of 25/128 implants occurred (19.5%). Five implants failed to osseointegrate and were removed. The remaining 20 complications were all managed or observed without management, with implants surviving at mid-term follow-up. CONCLUSIONS: Notwithstanding technique sensitivity and the need for randomized control studies, this case series demonstrates that the socket-shield performs competitively when compared to implant survival rates in both conventional immediate and delayed implant placement.

AB - The physicochemical behavior of fullerene C60 in hydrocarbon solvents is examined by isothermal titration calorimetry, photocalorimetry, and UV spectroscopy. The obtained data are summarized to substantiate the idea of the binary fullerene/solvent cluster as a colloidal nanoentity that moderates noncovalent interactions of the C60 molecule in solution. This idea serves to aid understanding of the complex physicochemical behavior of tert-butyl-substituted phthalocyanine in C60 -saturated o-xylene under illumination with low-energy photons. The proposed experimental approach, which focuses on concentrated solutions and is applicable to multicomponent systems, is discussed as a potential tool of materials science.

AB - Metal-organic frameworks (MOFs), also called porous coordination polymers, represent a class of crystalline porous materials built from organic linkers and metal ions/clusters. The unique features of MOFs, including structural diversity and tailorability as well as high surface area, etc., enable them to be a highly versatile platform for potential applications in many fields. Herein, an overview of recent developments achieved in MOF catalysis, including heterogeneous catalysis, photocatalysis, and eletrocatalysis over MOFs and MOF-based materials, is provided. The active sites involved in the catalysts are particularly emphasized. The challenges, future trends, and prospects associated with MOFs and their related materials for catalysis are also discussed.

PMID- 29178386 TI - A new parameter-rich structure-aware mechanistic model for amino acid substitution during evolution. AB - Improvements in the description of amino acid substitution are required to develop better pseudo-energy-based protein structure-aware models for use in phylogenetic studies. These models are used to characterize the probabilities of amino acid substitution and enable better simulation of protein sequences over a phylogeny. A better characterization of amino acid substitution probabilities in turn enables numerous downstream applications, like detecting positive selection, ancestral sequence reconstruction, and evolutionarily-motivated protein engineering. Many existing Markov models for amino acid substitution in molecular evolution disregard molecular structure and describe the amino acid substitution process over longer evolutionary periods poorly. Here, we present a new model upgraded with a site-specific parameterization of pseudo-energy terms in a coarse grained force field, which describes local heterogeneity in physical constraints on amino acid substitution better than a previous pseudo-energy-based model with minimum cost in runtime. The importance of each weight term parameterization in characterizing underlying features of the site, including contact number, solvent accessibility, and secondary structural elements was evaluated, returning both expected and biologically reasonable relationships between model parameters. This results in the acceptance of proposed amino acid substitutions that more closely resemble those observed site-specific frequencies in gene family alignments. The modular site-specific pseudo-energy function is made available for download through the following website: https://liberles.cst.temple.edu/Software/CASS/index.html. PMID- 29178387 TI - Gallic Acid and Gallates in Human Health and Disease: Do Mitochondria Hold the Key to Success? AB - Gallic acid and gallate esters are widely used as dietary supplements or additives with clinical significances. Over the last few decades, a large number of publications have been reported stating the antioxidative, antiapoptotic, cardioprotective, neuroprotective, and anticancer properties of gallic acid and gallates, and mostly demonstrated their antioxidative or prooxidative properties influencing the reactive oxygen species (ROS) signaling networks. However, very little focus has been paid to clinical trials, and this restricted their use as a prescribed preventative supplement. Since mitochondria are the principal organelles responsible for ROS generation, we reviewed the existing literature of mitochondria-specific effects of gallates including ROS production, respiration, mitochondrial biogenesis, apoptosis, and the physico-chemical parameters affecting the outcome of gallate supplementation to various health scenarios such as cardiovascular diseases, neurodegeneration, hepatic ailments, or cancers. The major signaling pathways and the molecules targeted by gallic acid and its derivatives have also been discussed with emphasis on mitochondria as the target site. This review provides a better understanding of the effect of gallic acid and gallate esters on mitochondrial functions and in designing effective preventative measures against the onset of various diseases. PMID- 29178388 TI - Synthesis of Carbon Dots with Multiple Color Emission by Controlled Graphitization and Surface Functionalization. AB - Multiple-color-emissive carbon dots (CDots) have potential applications in various fields such as bioimaging, light-emitting devices, and photocatalysis. The majority of the current CDots to date exhibit excitation-wavelength-dependent emissions with their maximum emission limited at the blue-light region. Here, a synthesis of multiple-color-emission CDots by controlled graphitization and surface function is reported. The CDots are synthesized through controlled thermal pyrolysis of citric acid and urea. By regulating the thermal-pyrolysis temperature and ratio of reactants, the maximum emission of the resulting CDots gradually shifts from blue to red light, covering the entire light spectrum. Specifically, the emission position of the CDots can be tuned from 430 to 630 nm through controlling the extent of graphitization and the amount of surface functional groups, ?COOH. The relative photoluminescence quantum yields of the CDots with blue, green, and red emission reach up to 52.6%, 35.1%, and 12.9%, respectively. Furthermore, it is demonstrated that the CDots can be uniformly dispersed into epoxy resins and be fabricated as transparent CDots/epoxy composites for multiple-color- and white-light-emitting devices. This research opens a door for developing low-cost CDots as alternative phosphors for light emitting devices. PMID- 29178389 TI - Mass spectrometry of aerosol particle analogues in molecular beam experiments. AB - Nanometer-size particles such as ultrafine aerosol particles, ice nanoparticles, water nanodroplets, etc, play an important, however, not yet fully understood role in the atmospheric chemistry and physics. These species are often composed of water with admixture of other atmospherically relevant molecules. To mimic and investigate such particles in laboratory experiments, mixed water clusters with atmospherically relevant molecules can be generated in molecular beams and studied by various mass spectrometric methods. The present review demonstrates that such experiments can provide unprecedented details of reaction mechanisms, and detailed insight into the photon-, electron-, and ion-induced processes relevant to the atmospheric chemistry. After a brief outline of the molecular beam preparation, cluster properties, and ionization methods, we focus on the mixed clusters with various atmospheric molecules, such as hydrated sulfuric acid and nitric acid clusters, Nx Oy and halogen-containing molecules with water. A special attention is paid to their reactivity and solvent effects of water molecules on the observed processes. PMID- 29178390 TI - FOXO protects against age-progressive axonal degeneration. AB - Neurodegeneration resulting in cognitive and motor impairment is an inevitable consequence of aging. Little is known about the genetic regulation of this process despite its overriding importance in normal aging. Here, we identify the Forkhead Box O (FOXO) transcription factor 1, 3, and 4 isoforms as a guardian of neuronal integrity by inhibiting age-progressive axonal degeneration in mammals. FOXO expression progressively increased in aging human and mouse brains. The nervous system-specific deletion of Foxo transcription factors in mice accelerates aging-related axonal tract degeneration, which is followed by motor dysfunction. This accelerated neurodegeneration is accompanied by levels of white matter astrogliosis and microgliosis in middle-aged Foxo knockout mice that are typically only observed in very old wild-type mice and other aged mammals, including humans. Mechanistically, axonal degeneration in nerve-specific Foxo knockout mice is associated with elevated mTORC1 activity and accompanying proteotoxic stress due to decreased Sestrin3 expression. Inhibition of mTORC1 by rapamycin treatment mimics FOXO action and prevented axonal degeneration in Foxo knockout mice with accelerated nervous system aging. Defining this central role for FOXO in neuroprotection during mammalian aging offers an invaluable window into the aging process itself. PMID- 29178392 TI - SLC34A2 regulates miR-25-Gsk3beta signaling pathway to affect tumor progression in gastric cancer stem cell-like cells. AB - A novel paradigm in tumor biology suggests that gastric cancer progression is driven by gastric cancer stem cell-like cells (GCSCs), but molecular mechanisms regulating tumorigenic and self-renewal potential of GCSCs are still unclear. Here, we aim to investigate biological function of SLC34A2 in regulating sphere formation and tumorigenicity (both are the hallmark of CSCs) of GCSCs and its underlying mechanisms. Our findings testified that CD44+ cells which were derived from fresh primary gastric cancer samples and cell lines displayed stem cell-like features. Significantly, SLC34A2 is increased in CD44+ GCSCs compared with those in adherent counterpart from CD44+ GCSCs. On clinic, SLC34A2 is overexpressed in primary tumor tissues compared with adjacent counterparts. We showed that SLC34A2 regulated sphere formation and self-renewal properties of CD44+ GCSCs in vitro and in vivo. Mechanistic investigations revealed that Gsk3beta was the most strikingly up-regulated gene in response to SLC34A2 knockdown in GCSCs and Wnt/beta-cantenin signaling was required for SLC34A2-mediated sphere formation. Furthermore, SLC34A2 directly binds specific sites in the miR-25 promoter region and that the promoter activity is decreased after the mutation of putative SLC34A2-binding sites, indicating that SLC34A2 is required for the transcriptional induction of miR-25. Meanwhile, luciferase assays showed that miR 25 directly targeted Gsk3beta in CD44+ GCSCs. Overall, our findings define a SLC34A2-miR-25-Gsk3beta pathway in the regulation of GCSCs features and gastric cancer progression, with potential therapeutic applications in blocking their progression. PMID- 29178393 TI - What makes a good head positioner for preventing occipital pressure ulcers. AB - Patients who are stationary endure prolonged soft tissue distortions and deformations at contact areas between their body and the support surface, which may lead to the onset of pressure ulcers (PUs) over time. A novel technology for patient positioning employs innovation in materials science, specifically viscoelastic materials with shape memory properties that compose the Z-FloTM head positioner (Molnlycke Health Care, Gothenburg, Sweden). Head positioners are generally known to reduce the occurrence of PUs in scalp tissues and the ears, but quantitative assessments of their biomechanical efficacy are missing in the literature. To determine potential differences in mechanical loads formed in the soft tissues of the back of the head while in contact with 2 head positioner types, Z-Flo vs flat medical foam, we developed 2 comparable finite element model configurations, both including the same 3-dimensional adult head. For both model variants, stresses in skin and fat peaked at the occiput. The skin at the back of the resting head is subjected to greater stress values with respect to fat; however, the Z-Flo positioner reduced the exposure of both skin and fat tissues to elevated stresses considerably (by a factor of 3) compared to the medical foam support. We found the Z-Flo device effective in reducing tissue loads at the surface of the head as well as internally in scalp tissues, with a particular strength in reducing internal tissue shear. The Z-Flo device achieves this protective quality through highly effective immersion and envelopment of the back of the head, generated in the process of manual moulding of the device in preparation for use. Additional protection is achieved through the viscoelastic response of the filling material of this positioner, which relaxes promptly and considerably under the weight of the head (by more than 2-fold within approximately 1 s) as opposed to the elastic recoil of the foam that pushes back on scalp tissues. PMID- 29178391 TI - Peptidoglycan in obligate intracellular bacteria. AB - Peptidoglycan is the predominant stress-bearing structure in the cell envelope of most bacteria, and also a potent stimulator of the eukaryotic immune system. Obligate intracellular bacteria replicate exclusively within the interior of living cells, an osmotically protected niche. Under these conditions peptidoglycan is not necessarily needed to maintain the integrity of the bacterial cell. Moreover, the presence of peptidoglycan puts bacteria at risk of detection and destruction by host peptidoglycan recognition factors and downstream effectors. This has resulted in a selective pressure and opportunity to reduce the levels of peptidoglycan. In this review we have analysed the occurrence of genes involved in peptidoglycan metabolism across the major obligate intracellular bacterial species. From this comparative analysis, we have identified a group of predicted 'peptidoglycan-intermediate' organisms that includes the Chlamydiae, Orientia tsutsugamushi, Wolbachia and Anaplasma marginale. This grouping is likely to reflect biological differences in their infection cycle compared with peptidoglycan-negative obligate intracellular bacteria such as Ehrlichia and Anaplasma phagocytophilum, as well as obligate intracellular bacteria with classical peptidoglycan such as Coxiella, Buchnera and members of the Rickettsia genus. The signature gene set of the peptidoglycan intermediate group reveals insights into minimal enzymatic requirements for building a peptidoglycan-like sacculus and/or division septum. PMID- 29178394 TI - Maturation in auditory event-related potentials explains variation in language ability in children. AB - Processing of auditory information in the cortex continues to develop into later childhood and adolescence. Recent research has indicated that intraclass correlation (ICC) is the best method for capturing maturation in auditory event related potentials (AEPs) of school-age children. However, the sensitivity of the ICC approach in discerning AEP changes in children has not been consistently demonstrated and positive results have not been replicated. We attempted this replication and further explored whether AEP maturation estimated using the ICC approach predicts cognitive and linguistic abilities in addition to chronological age. We measured AEPs in response to simple tones in groups of 7-, 8-, 9- and 10 year olds with typical development (N = 67) and used ICC to estimate the age equivalent of each child's AEP (AEP-age). Results indicated that ICC differentiated 7- to 8-year-old children from 9- to 10-year-old children and that AEP-age predicted both chronological age and significant, unique variance in language ability, but not in nonverbal IQ. Our findings support the view that auditory organization in children reflects both general developmental maturation and more specific development of language skills, and support the future use of AEP-age to identify and understand individual differences in brain maturation in typically developing and clinical populations. PMID- 29178395 TI - Megafaunal effects on vegetation structure throughout a densely wooded African landscape. AB - Megafauna strongly affect vegetation structure and composition, often leading to management concern. However, the extent of their influence across large scales and varying ecosystems remains largely unknown. Using high resolution airborne Light Detection and Ranging (LiDAR), we investigated landscape-scale changes in vegetation height and three-dimensional (3D) structure across landscapes of varying elephant densities and presence over time, and in response to surface water distribution and terrain variability in the heavily managed thicket biome of the Addo Elephant National Park, South Africa. Elephants caused up to a fourfold reduction in vegetation height and altered the vertical profile, but increased vegetation height variability. Vegetation height also increased with elevation and distance from water, particularly in areas that elephants had long occupied at high densities. Slope had opposing effects on vegetation height, with height increasing with slope in areas long exposed to elephants, but decreasing where elephants had only recently been granted access. Our results suggest that elephants are the primary agents of vegetation change in this ecosystem, but that the strength of their effects varies across the landscape, enabling management to use water and terrain as mitigation tools. We further highlight the necessity of landscape-level experimental studies on megafaunal effects to untangle mechanisms and establish causality. PMID- 29178396 TI - Dermoscopic features of endocrine mucin-producing sweat gland carcinoma. AB - Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is very rare, with only 61 cases reported to date. EMPSGC is considered to be a low-grade carcinoma of sweat gland origin. Dermoscopic findings of EMPSGC have not been previously reported. We report the first case of a man with EMPSGC, featuring dermoscopic findings. Dermoscopic examinations of the present EMPSGC lesion revealed tumor cell proliferation that appeared as pink ovoid nests and elongated epidermis that resembled a whitish-pink network. Another characteristic finding of the present lesion was the large red/blue globules in pink ovoid nests in the tumor. Those reflected lacunae containing secretory fluid with red blood cells. We think that the large red/blue globules in pink ovoid nests in our case could be a characteristic dermoscopic finding specific to EMPSGC. We dermatologists encounter many "pink nodules" at out-patient clinics. The present dermoscopic findings may be useful for the differential diagnosis of EMPSGC. PMID- 29178397 TI - Review: The transcripts associated with organ allograft rejection. AB - The molecular mechanisms operating in human organ transplant rejection are best inferred from the mRNAs expressed in biopsies because the corresponding proteins often have low expression and short half-lives, while small non-coding RNAs lack specificity. Associations should be characterized in a population that rigorously identifies T cell-mediated (TCMR) and antibody-mediated rejection (ABMR). This is best achieved in kidney transplant biopsies, but the results are generalizable to heart, lung, or liver transplants. Associations can be universal (all rejection), TCMR-selective, or ABMR-selective, with universal being strongest and ABMR selective weakest. Top universal transcripts are IFNG-inducible (eg, CXCL11 IDO1, WARS) or shared by effector T cells (ETCs) and NK cells (eg, KLRD1, CCL4). TCMR selective transcripts are expressed in activated ETCs (eg, CTLA4, IFNG), activated (eg, ADAMDEC1), or IFNG-induced macrophages (eg, ANKRD22). ABMR selective transcripts are expressed in NK cells (eg, FGFBP2, GNLY) and endothelial cells (eg, ROBO4, DARC). Transcript associations are highly reproducible between biopsy sets when the same rejection definitions, case mix, algorithm, and technology are applied, but exact ranks will vary. Previously published rejection-associated transcripts resemble universal and TCMR-selective transcripts due to incomplete representation of ABMR. Rejection-associated transcripts are never completely rejection-specific because they are shared with the stereotyped response-to-injury and innate immunity.

AB - We report a case of chromoblastomycosis due to the presence of large plaque and verrucous hyperplasia lesions on the left upper limb, with elbow abnormal activities, in a 56-year-old male. The diagnosis of chromoblastomycosis was based on gross and microscopic morphologies, histopathological examination and clinical manifestation. Molecular tools were applied to identifying the causative agent Fonsecaea nubica, which is rarely reported to be associated with chromoblastomycosis. The patient was initially treated orally with terbinafine (250 mg/day) and itraconazole (200 mg/day), subsequently patient received thermotherapy (45-50 degrees C, 3 h/day) for 1 month. The patient was successfully cured. A literature review was performed to assess general features, treatment and outcome of chromoblastomycosis due to F. nubica. All the 5 reviewed patients were male, over 30 years old and their lesions occurred after traumatic inoculation.

AB - Lignocellulosic biomass conversion into value-added platform chemicals in the non toxic, water-tolerant Lewis acid, and water solutions bears the hallmark of green chemistry. Lactic acid derived from biomass is an important chemical building block for biodegradable polymers such as polylactide. Herein, a universal method of converting lignocellulosic sugars into lactic acid using catalytic amount of water-stable Lewis acid La(OTf)3 is demonstrated. The lignocellulosic sugars studied in this work include 1) pyrolytic sugars from pyrolysis oil, and 2) sugars derived from ionic liquid (IL)-pretreated biomass. Under moderate conditions (250 degrees C, 1 h), levoglucosan (major pyrolytic sugar), glucose, and xylose were converted into lactic acid with carbon-based molar yields of 75, 74, and 61 %, respectively. Furthermore, roughly 49 mol % (based on levoglucosan) and 74 wt % (relative to pretreated biomass) of lactic acid were obtained from the conversion of pyrolytic sugars and sugar-rich fraction after lignin removal from switchgrass, respectively. To our knowledge, this is the first reported conversion of pyrolytic sugar into lactic acid by chemocatalysis and also lignocellulosic sugars are converted into lactic acid without hydrolysis. This approach could potentially be extended to other lignocellulosic sugars after simple removal of lignin from biomass pretreatment, rendering moderate to high yields of lactic acid. PMID- 29178400 TI - Evaluating clinical stop-smoking services globally: towards a minimum data set. AB - BACKGROUND AND AIMS: Behavioural and pharmacological support for smoking cessation improves the chances of success and represents a highly cost-effective way of preventing chronic disease and premature death. There is a large number of clinical stop-smoking services throughout the world. These could be connected into a global network to provide data to assess what treatment components are most effective, for what populations and in what settings. To enable this, a minimum data set (MDS) is required to standardize the data captured from smoking cessation services globally. METHODS: We describe some of the key steps involved in developing a global MDS for smoking cessation services and methodologies to be considered for their implementation, including approaches for reaching consensus on data items to include in a MDS and for its robust validation. We use informal approximations of these methods to produce an example global MDS for smoking cessation. Our aim with this is to stimulate further discussion around the development of a global MDS for smoking cessation services. RESULTS: Our example MDS comprises three sections. The first is a set of data items characterizing treatments offered by a service. The second is a small core set of data items describing clients' characteristics, engagement with the service and outcomes. The third is an extended set of client data items to be captured in addition to the core data items wherever resources permit. CONCLUSIONS: There would be benefit in establishing a minimum data set (MDS) to standardize data captured for smoking cessation services globally. Once implemented, a formal MDS could provide a basis for meaningful evaluations of different smoking cessation treatments in different populations in a variety of settings across many countries. PMID- 29178401 TI - Childhood cancer incidence and survival in Japan and England: A population-based study (1993-2010). AB - The present study aimed to compare cancer incidence and trends in survival for children diagnosed in Japan and England, using population-based cancer registry data. The analysis was based on 5192 children with cancer (age 0-14 years) from 6 prefectural cancer registries in Japan and 21 295 children diagnosed in England during 1993-2010. Differences in incidence rates between the 2 countries were measured with Poisson regression models. Overall survival was estimated using the Kaplan-Meier method. Incidence rates for Hodgkin lymphoma, renal tumors and Ewing sarcomas in England were more than twice as high as those in Japan. Incidence of germ cell tumors, hepatic tumors, neuroblastoma and acute myeloid leukemia (AML) was higher in Japan than in England. Incidence of all cancers combined decreased in Japan throughout the period 1993 to 2010, which was mainly explained by a decrease in registration of neuroblastoma in infants. For many cancers, 5-year survival improved in both countries. The improvement in survival in chronic myeloid leukemia (CML) was particularly dramatic in both countries. However, 5 year survival remained less than 80% in 2005-2008 in both countries for AML, brain tumors, soft tissue sarcomas, malignant bone tumors and neuroblastoma (age 1-14 years). There were significant differences in incidence of several cancers between countries, suggesting variation in genetic susceptibility and possibly environmental factors. The decrease in incidence for all cancers combined in Japan was related to the cessation of the national screening program for neuroblastoma. The large improvement in survival in CML coincided with the introduction of effective therapy (imatinib).

AB - Bone tissue engineering strategies utilize biodegradable polymeric matrices alone or in combination with cells and factors to provide mechanical support to bone, while promoting cell proliferation, differentiation, and tissue ingrowth. The performance of mechanically competent, micro-nanostructured polymeric matrices, in combination with bone marrow stromal cells (BMSCs), is evaluated in a critical sized bone defect. Cellulose acetate (CA) is used to fabricate a porous microstructured matrix. Type I collagen is then allowed to self-assemble on these microstructures to create a natural polymer-based, micro-nanostructured matrix (CAc). Poly (lactic-co-glycolic acid) matrices with identical microstructures serve as controls. Significantly higher number of implanted host cells are distributed in the natural polymer based micro-nanostructures with greater bone density and more uniform cell distribution. Additionally, a twofold increase in collagen content is observed with natural polymer based scaffolds. This study establishes the benefits of natural polymer derived micro-nanostructures in combination with donor derived BMSCs to repair and regenerate critical sized bone defects. Natural polymer based materials with mechanically competent micro nanostructures may serve as an alternative material platform for bone regeneration.

AB - Anti-CD20 recombinant antibodies are among the most promising therapeutics for the treatment of B-cell malignancies such as non-Hodgkin lymphomas. We recently demonstrated that an immunocytokine (2B8-Fc-hIL2), obtained by fusing an anti CD20 scFv-Fc antibody derived from C2B8 mAb (rituximab) to the human interleukin 2 (hIL-2), can be efficiently produced in Nicotiana benthamiana plants. The purified immunocytokine (IC) bearing a typical plant protein N-glycosylation profile showed a CD20 binding activity comparable to that of rituximab and was efficient in eliciting antibody-dependent cell-mediated cytotoxicity (ADCC) of human PBMC against Daudi cells, indicating its fuctional integrity. In this work, the immunocytokine devoid of the typical xylose/fucose N-glycosylation plant signature (IC-DeltaXF) and the corresponding scFv-Fc-DeltaXF antibody not fused to the cytokine, were obtained in a glyco-engineered DeltaXylT/FucT N. benthamiana line. Purification yields from agroinfiltrated plants amounted to 20 35 mg/kg of leaf fresh weight. When assayed for interaction with FcgammaRI and FcgammaRIIIa, IC-DeltaXF exhibited significantly enhanced binding affinities if compared to the counterpart bearing the typical plant protein N-glycosylation profile (IC) and to rituximab. The glyco-engineered recombinant molecules also exhibited a strongly improved ADCC and complement-dependent cytotoxicity (CDC). Notably, our results demonstrate a reduced C1q binding of xylose/fucose carrying IC and scFv-Fc compared to versions that lack these sugar moieties. These results demonstrate that specific N-glycosylation alterations in recombinant products can dramatically affect the effector functions of the immunocytokine, resulting in an overall improvement of the biological functions and consequently of the therapeutic potential. PMID- 29178404 TI - The impact of rickets on growth and morbidity during recovery among children with complicated severe acute malnutrition in Kenya: A cohort study. AB - The effects of rickets on children recovery from severe acute malnutrition (SAM) are unknown. Rickets may affect both growth and susceptibility to infectious diseases. We investigated the associations of clinically diagnosed rickets with life-threatening events and anthropometric recovery during 1 year following inpatient treatment for complicated SAM. This was a secondary analysis of clinical trial data among non-human immunodeficiency virus-infected Kenyan children with complicated SAM (2-59 months) followed for 1 year posthospital discharge (ClinicalTrials.gov ID NCT00934492). The outcomes were mortality, hospital readmissions, and growth during 12 months. The main exposure was clinically diagnosed rickets at baseline. Of 1,778 children recruited, 230 (12.9%, 95% CI [11.4, 14 .6]) had clinical signs of rickets at baseline. Enrolment at an urban site, height-for-age and head circumference-for-age z scores were associated with rickets. Rickets at study enrolment was associated with increased mortality (adjusted Hazard Ratio [aHR] 1.61, 95% CI [1.14, 2.27]), any readmission (aHR 1.37, 95% CI [1.09, 1.72]), readmission for severe pneumonia (aHR 1.37, 95% CI [1.05, 1.79]), but not readmission with diarrhoea (aHR 1.05, 95% CI [0.73, 1.51]). Rickets was associated with increased height gain (centimetres), adjusted regression coefficient 0.19 (95% CI [0.10, 0.28]), but not changes in head circumference, mid-upper arm circumference, or weight. Rickets was common among children with SAM at urban sites and associated with increased risks of severe pneumonia and death. Increased height gain may have resulted from vitamin D and calcium treatment. Future work should explore possibility of other concurrent micronutrient deficiencies and optimal treatment of rickets in this high-risk population. PMID- 29178405 TI - Acoustophoretic separation of infected erythrocytes from blood plasma in a microfluidic platform using biofunctionalized, matched-impedance layers. AB - Acoustophoresis is rapidly gaining prominence in the field of cell manipulation. In recent years, researchers have extensively used this method for separating different types of cells from the bulk fluid. In this paper, we propose a novel acoustophoresis-based technique to capture infected or abnormal erythrocytes from blood plasma. A typical acoustic device consisting of a transducer assembly, microfluidic cavity, and a reflector is considered. Based on the concept of impedance matching, a pair of antibody-coated polystyrene layers is placed in the nodal regions of an acoustic field within the cavity. This technique allows bi directional migration of the suspended cells to the biofunctionalized surfaces. Therefore, simultaneous capture of infected erythrocytes on both the layers is feasible. Finite element method is used to model the pressure field as well as the motion of erythrocytes under the influence of acoustic radiation, drag, and gravitational forces. A parametric analysis is done by varying the excitation frequency, driving voltage, and the thickness of the polystyrene layers. The resulting changes in the pressure amplitude and field pattern are investigated. The erythrocyte collection efficiency, rate of collection, and the cell distribution on the layer surfaces are also determined under different field conditions. The occurrence of transient cavitation in the blood plasma-filled cavity at the chosen frequency is taken into account by using its threshold pressure value as the limiting factor of pressure amplitude. The study provides an insight into the phenomenon and serves as a guideline to fabricate low-cost, multifunctional rapid diagnostic devices based on acoustophoretic separation. PMID- 29178406 TI - Tsuji-Trost Reaction of Non-Derivatized Allylic Alcohols. AB - Palladium-catalyzed allylic substitution of non-derivatized enantioenriched allylic alcohols with a variety of uncharged N-, S-, C- and O-centered nucleophiles using a bidentate BiPhePhos ligand is described. A remarkable effect of the counter ion (X) of the XPd[kappa2 -BiPhePhos][eta3 -C3 H5 ] was observed. When ClPd[kappa2 -BiPhePhos][eta3 -C3 H5 ] (complex I) was used as catalyst, non reproducible results were obtained. Study of the complex by X-ray crystallography, 31 P NMR spectroscopy, and ESI-MS showed that a decomposition occurred where one of the phosphite ligands was oxidized to the corresponding phosphate, generating ClPd[kappa1 -BiPhePhosphite-phosphate][eta3 -C3 H5 ] species (complex II). When the chloride was exchanged to the weaker coordinating OTf- counter ion the more stable Pd[kappa2 -BiPhePhos][eta3 -C3 H5 ]+ +[OTf] - (complex III) was formed. Complex III performed better and gave higher enantiospecificities in the substitution reactions. Complex III was evaluated in Tsuji-Trost reactions of stereogenic non-derivatized allylic alcohols. The desired products were obtained in good to excellent yields (71-98 %) and enantiospecificities (73-99 %) for both inter- and intramolecular substitution reactions with only water generated as a by-product. The methodology was applied to key steps in total synthesis of (S)-cuspareine and (+)-lentiginosine. A reaction mechanism involving a palladium hydride as a key intermediate in the activation of the hydroxyl group is proposed in the overall transformation. PMID- 29178407 TI - A meta-analysis of the association between Helicobacter pylori (H. pylori) infection and hyperemesis gravidarum. AB - BACKGROUND: Hyperemesis gravidarum remains a common, distressing, and significant yet poorly understood disorder during pregnancy. The association between maternal Helicobacter pylori (H. pylori) infection and hyperemesis gravidarum has been increasingly recognized and investigated. This study thus aimed to provide an updated review and meta-analysis of the topic. METHODS: Using the search terms (H. pyloriOR Helicobacter ORHelicobacter pyloriOR infection) AND (pregnancy OR emesis OR hyperemesis gravidarum OR nausea OR vomiting), a preliminary search on the PubMed, Ovid, Web of Science, Google Scholar, and WanFang database yielded 372 papers published in English between January 1st, 1960 and June 1st, 2017. RESULTS: A total of 38 cross-sectional and case-control studies, with a total of 10 289 patients were eligible for review. Meta-analysis revealed a significant association between H. pylori infection and hyperemesis gravidarum during pregnancy, with a pooled odds ratio of 1.348 (95% CI: 1.156-1.539, P < .001). Subgroup analysis found that serologic and stool antigen tests were comparable methods of detecting H. pylori as they yielded similar odds ratios. LIMITATIONS: Although the studies did not have high heterogeneity (I2 = 28%), publication bias was observed, and interstudy discrepancies in the diagnostic criteria adopted for hyperemesis gravidarum limit the reliability of findings. Also, 15 of the included studies were from the same country (Turkey), which could limit the generalizability of current findings. The prevalence of H. pylori infection varies throughout the world, and there may also be pathogenic differences as most strains of H. pylori in East Asia carry the cytotoxin-associated gene A gene. CONCLUSION: H. pylori infection was associated with an increased likelihood of hyperemesis gravidarum during pregnancy. Given the high prevalence of H. pylori infections worldwide, detecting H. pylori infection and the eradication of maternal H. pylori infection could be part of maternal hyperemesis gravidarum management. Further confirmation with robust longitudinal studies and mechanistic investigations are needed. PMID- 29178408 TI - Spousal recollections of early signs of primary progressive aphasia. AB - BACKGROUND: Although primary progressive aphasia (PPA) is characterized by progressive loss of language and communication skills, knowledge about the earliest emerging signs announcing the onset of this condition is limited. AIMS: To explore spousal recollections regarding the earliest signs of PPA and to compare the nature of the earliest perceived symptoms across the three PPA variants. METHODS & PROCEDURES: In-depth interviews focusing on the earliest signs of illness onset were conducted with 13 spouses whose partners were diagnosed with PPA. The earliest recollections and observations described by the spouses were analyzed and coded according to the DSM-5 criteria for a mild neurocognitive disorder. These data were then compared across and within each of the three PPA variants. OUTCOMES & RESULTS: Spousal retrospective accounts indicated the three PPA variants (semantic, logopenic and non-fluent) had a signature profile announcing illness onset. Changes in social cognition presented in all three variants of PPA, but at different points in the illness trajectory. In particular, the findings suggest the possibility that PPA initially presents as subtle changes in social cognition for semantic variant PPA (svPPA) and logopenic variant PPA (IvPPA) rather than overt language impairments as defined in the current diagnostic criteria. CONCLUSIONS & IMPLICATIONS: Understanding the nature of symptoms perceived in the earliest stages of PPA has potential to inform earlier and accurate diagnosis and interventions to assist those living with the illness. PMID- 29178410 TI - Genome sequences of Chlorella sorokiniana UTEX 1602 and Micractinium conductrix SAG 241.80: implications to maltose excretion by a green alga. AB - Green algae represent a key segment of the global species capable of photoautotrophic-driven biological carbon fixation. Algae partition fixed-carbon into chemical compounds required for biomass, while diverting excess carbon into internal storage compounds such as starch and lipids or, in certain cases, into targeted extracellular compounds. Two green algae were selected to probe for critical components associated with sugar production and release in a model alga. Chlorella sorokiniana UTEX 1602 - which does not release significant quantities of sugars to the extracellular space - was selected as a control to compare with the maltose-releasing Micractinium conductrix SAG 241.80 - which was originally isolated from an endosymbiotic association with the ciliate Paramecium bursaria. Both strains were subjected to three sequencing approaches to assemble their genomes and annotate their genes. This analysis was further complemented with transcriptional studies during maltose release by M. conductrix SAG 241.80 versus conditions where sugar release is minimal. The annotation revealed that both strains contain homologs for the key components of a putative pathway leading to cytosolic maltose accumulation, while transcriptional studies found few changes in mRNA levels for the genes associated with these established intracellular sugar pathways. A further analysis of potential sugar transporters found multiple homologs for SWEETs and tonoplast sugar transporters. The analysis of transcriptional differences revealed a lesser and more measured global response for M. conductrix SAG 241.80 versus C. sorokiniana UTEX 1602 during conditions resulting in sugar release, providing a catalog of genes that might play a role in extracellular sugar transport. PMID- 29178411 TI - Increased plasma oleoylethanolamide and palmitoleoylethanolamide levels correlate with inflammatory changes in alcohol binge drinkers: the case of HMGB1 in women. AB - Alcohol binge drinking is a heavy pattern of alcohol consumption increasingly used by young people. In a previous study, we reported that young drinkers with a 2-year history of binge alcohol consumption had an overactivation of the innate immune system and peripheral inflammation when compared with controls. In the present study, we measured several biolipids that are fatty acid derivatives belonging to the acylethanolamide or 2-acylglycerol families in the plasma of the same subjects (n = 42; 20 men and 22 women). We found that during abstinence, alcohol binge drinkers had elevated plasma levels of oleoylethanolamide, palmitoleoylethanolamide, arachidonoylethanolamide, dihomo-gamma-linolenoyl ethanolamide and linoleoyl ethanolamide, which positively correlated with changes in the mRNA expression of key inflammatory markers in peripheral blood mononuclear cells, such as toll-like receptors (TLR4), pro-inflammatory cytokines/chemokines interleukin-1 beta, interleukin-6 and monocyte chemoattractant protein-1, and cyclooxygenase-2. Additionally, plasma oleoylethanolamide positively correlated with plasma levels of high mobility group box-1, which is a danger-associated molecular pattern and an endogenous TLR4 agonist, specifically in female alcohol binge drinkers. No changes were observed in 2-acylglycerols in alcohol binge drinkers, although sex-related differences in these bioactive lipids as well as in palmitoleoylethanolamide and docosatetraenoylethanolamide levels were detected. These results extend the previous clinical findings observed in patients diagnosed with long-term alcohol use disorder to young users and suggest a prominent role for these lipids in the response to acute alcohol exposure. PMID- 29178409 TI - Sox2 regulates astrocytic and vascular development in the retina. AB - Sox2 is a transcriptional regulator that is highly expressed in retinal astrocytes, yet its function in these cells has not previously been examined. To understand its role, we conditionally deleted Sox2 from the population of astrocytes and examined the consequences on retinal development. We found that Sox2 deletion does not alter the migration of astrocytes, but it impairs their maturation, evidenced by the delayed upregulation of glial fibrillary acidic protein (GFAP) across the retina. The centro-peripheral gradient of angiogenesis is also delayed in Sox2-CKO retinas. In the mature retina, we observed lasting abnormalities in the astrocytic population evidenced by the sporadic loss of GFAP immunoreactivity in the peripheral retina as well as by the aberrant extension of processes into the inner retina. Blood vessels in the adult retina are also under developed and show a decrease in the frequency of branch points and in total vessel length. The developmental relationship between maturing astrocytes and angiogenesis suggests a causal relationship between the astrocytic loss of Sox2 and the vascular architecture in maturity. We suggest that the delay in astrocytic maturation and vascular invasion may render the retina hypoxic, thereby causing the abnormalities we observe in adulthood. These studies uncover a novel role for Sox2 in the development of retinal astrocytes and indicate that its removal can lead to lasting changes to retinal homeostasis. PMID- 29178412 TI - Temperature-Directed Biocatalysis for the Sustainable Production of Aromatic Aldehydes or Alcohols. AB - The biosynthesis of aromatic aldehydes and alcohols from renewable resources is currently receiving considerable attention because of an increase in demand, finite fossil resources, and growing environmental concerns. Here, a temperature directed whole-cell catalyst was developed by using two novel enzymes from a thermophilic actinomycete. Ferulic acid, a model lignin derivative, was efficiently converted into vanillyl alcohol at a reaction temperature at 30 degrees C. However, when the temperature was increased to 50 degrees C, ferulic acid was mainly converted into vanillin with a productivity of 1.1 g L-1 h-1 . This is due to the fact that the redundant endogenous alcohol dehydrogenases (ADHs) are not active at this temperature while the functional enzymes from the thermophilic strain remain active. As the biocatalyst could convert many other renewable cinnamic acid derivatives into their corresponding aromatic aldehydes/alcohols, this novel strategy may be extended to generate a vast array of valuable aldehydes or alcohols. PMID- 29178413 TI - In vivo reflectance confocal microscopy in daily practice: Image features correlated to histopathology. AB - BACKGROUND: In vivo reflectance confocal microscopy (RCM) represents a promising technique for noninvasive visualization of skin lesions. In the clinical daily practice, doctors want to know the relationship between the RCM images and the skin pathological changes. OBJECTIVE: The aim of this study was to identify the basic skin pathological changes under RCM, and use RCM terminology to describe these pathological changes. METHODS: A total of 100 patients were recruited and were evaluated both by RCM and histopathologic examination. Ten healthy volunteers were also recruited as control. RCM examinations were done and biopsies of the lesions at the same site of RCM examination were performed for histopathology analysis. RESULTS: The pathological changes including hyperkeratosis, parakeratosis, acanthosis, papilloma, spongiosis, pustule, vacuolar degeneration, hyperpigmentation, changes of collagen fibers, and vascular changes can be imaged by RCM and corresponded well to their histopathology. RCM failed to find the atypical keratinocytes in two squamous cell carcinoma cases because of the hyperkeratosis and failed to find the vascular changes in one port wine stain cases because of the limitation of detecting depth. CONCLUSION: Features correlating well to histopathology are observed on RCM. RCM can be used as an auxiliary diagnosis tool for the clinical diagnosis. PMID- 29178414 TI - Developing and validating a multivariable prediction model to improve the diagnostic accuracy in determination of cervical versus endometrial origin of uterine adenocarcinomas: A prospective MR study combining diffusion-weighted imaging and spectroscopy. AB - BACKGROUND: A triage test to assist clinical decision-making on choosing primary chemoradiation for cervical carcinomas or primary surgery for endometrial carcinomas is important. PURPOSE OR HYPOTHESIS: To develop and validate a multiparametric prediction model based on MR imaging and spectroscopy in distinguishing adenocarcinomas of uterine cervical or endometrial origin. STUDY TYPE: Prospective diagnostic accuracy study. POPULATION: Eighty-seven women: 25 cervical and 62 endometrial adenocarcinomas divided into training (n = 43; cervical/endometrial adenocarcinomas = 11/32) and validation (n = 44; 14/30) datasets. FIELD STRENGTH/SEQUENCE: The 3T diffusion-weighted (DW) MR imaging and MR spectroscopy. ASSESSMENT: Morphology, volumetric DW MR imaging and spectroscopy (MDS) scoring system with total points 0-5, based on presence of the following MR features assessed independently by two radiologists: (a) epicenter at the cervix, (b) rim enhancement, (c) disrupted cervical stromal integrity, (d) mean volumetric apparent diffusion coefficient values (ADCmean) higher than 0.98 * 10-3 mm2 /s, (e) fatty acyl delta 1.3 ppm more than 161.92 mM. Histopathology as gold standard. STATISTICAL TESTS: Logistic regression and receiver operator characteristic (ROC) curves analysis. RESULTS: For both the training and validation datasets, the MDS score achieved an accuracy of 93.0% and 84.1%, significantly higher than that of morphology (88.4% and 79.5%), ADC value (74.4% and 68.2%), and spectroscopy (81.4% and 68.2%; P < 0.05 for all). The performances of the scoring were superior to the morphology in the training dataset (areas under the receiver operating characteristics curve [AUC] = 0.95 vs. 0.89; P = 0.046), but not in the validation dataset (AUC = 0.90 vs. 0.85; P = 0.289). DATA CONCLUSION: MDS score has potentials to improve distinguishing adenocarcinomas of cervical or endometrial origin, and warrants large-scale studies for further validation.

AB - AIM: Sigmoid volvulus is a condition with a tendency to recur if treated conservatively. Little is known about the best type of treatment or when to perform definitive surgery. The aim of this study was to review treatment, and assess the outcome, of sigmoid volvulus in adult patients treated at a Swedish university hospital. METHOD: The medical records of patients treated for sigmoid volvulus at Sahlgrenska University Hospital, Sweden from January 2000 to September 2016 were reviewed retrospectively. Median follow-up time was 8.3 years. RESULTS: One hundred and sixty-eight patients were included with a total of 453 admissions for sigmoid volvulus. Nonoperative decompression was attempted as the initial treatment in 438/453 (97%), with a success rate of 92% (403/438), which was not influenced by whether it was the first episode or a recurrence. Without planned surgery, recurrence occurred after 84% of successful nonoperative decompressions with a median of two recurrences (1-16). Recurrence was less common after the first episode compared with subsequent episodes. Median time until recurrence was 58 days. Mortality after planned surgery following successful decompression was 3.3% (2/61) compared with 13% (6/46) following emergency surgery. CONCLUSION: In our cohort, the recurrence rate of sigmoid volvulus following successful nonoperative decompression was high. Still, more than 20% of patients did not experience a recurrence after their first episode. Nonoperative decompression could thus be suggested as the sole treatment for the first episode of volvulus. However, after the second episode it is probable that early planned surgery would improve outcome and reduce health-care consumption. PMID- 29178416 TI - 2D Enzyme Cascade Network with Efficient Substrate Channeling by Swinging Arms. AB - In living cells, compartmentalized or membrane-associated enzymes are often assembled into large networks to cooperatively catalyze cascade reaction pathways essential for cellular metabolism. Here, we report the assembly of an artificial 2D enzyme network of two cascade enzymes-glucose-6-phosphate dehydrogenase (G6PDH) and lactate dehydrogenase (LDH)-on a wireframe DNA origami template. Swinging arms were used to facilitate the transport of the redox intermediate of NAD+ /NADH between enzyme pairs on the array. The assemblies of 2D enzyme networks were characterized by gel electrophoresis and visualized by atomic force microscopy (AFM). The spatial arrangements of multiple enzyme pairs were optimized to facilitate efficient substrate channeling by exploiting the programmability of DNA origami to manipulate the key parameters of swinging arm length and stoichiometry. Compared with a single enzyme pair, the 2D organized enzyme systems exhibited higher reaction efficiency due to the promoted transfer of intermediates within the network. PMID- 29178417 TI - Risk of epilepsy in surgical patients undergoing general or neuraxial anaesthesia. AB - Limited information is available on the risks of epilepsy after surgery in patients receiving general or neuraxial anaesthesia. Using Taiwan's National Health Insurance Research Database, we identified 1,478,977 patients aged >= 20 years who underwent surgery (required general or neuraxial anaesthesia with hospitalisation for more than one day) between 2004 and 2011. We selected 235,066 patients with general anaesthesia and 235,066 patients with neuraxial anaesthesia using a frequency-matching procedure for age and sex. We did not study those with co-existing epilepsy-related risk factors. The adjusted rate ratios (RRs) and 95% confidence intervals (CIs) of newly diagnosed epilepsy 1 year after surgery associated with general anaesthesia were analysed in the multivariate Poisson regression model. The one-year incidence of postoperative epilepsy for patients with general anaesthesia and neuraxial anaesthesia were 0.41 and 0.32 per 1000 persons, respectively, and the corresponding RR was 1.27 (95%CI 1.15-1.41). The association between general anaesthesia and postoperative epilepsy was significant in men (RR = 1.22; 95%CI 1.06-1.40), women (RR = 1.33; 95%CI 1.15 1.55) and 20-39-year-old patients. The risk of postoperative epilepsy increased in patients with general anaesthesia who had co-existing medical conditions and postoperative complications. PMID- 29178418 TI - Dense-core vesicle biogenesis and exocytosis in neurons lacking chromogranins A and B. AB - Chromogranin A and B (Cgs) are considered to be master regulators of cargo sorting for the regulated secretory pathway (RSP) and dense-core vesicle (DCV) biogenesis. To test this, we analyzed the release of neuropeptide Y (NPY) pHluorin, a live RSP reporter, and the distribution, number, and appearance of DCVs, in mouse hippocampal neurons lacking expression of CHGA and CHGB genes. qRT PCR analysis showed that expression of other granin family members was not significantly altered in CgA/B-/- neurons. As synaptic maturation of developing neurons depends on secretion of trophic factors in the RSP, we first analyzed neuronal development in standardized neuronal cultures. Surprisingly, dendritic and axonal length, arborization, synapse density, and synaptic vesicle accumulation in synapses were all normal in CgA/B-/- neurons. Moreover, the number of DCVs outside the soma, stained with endogenous marker Secretogranin II, the number of NPY-pHluorin puncta, and the total amount of reporter in secretory compartments, as indicated by pH-sensitive NPY-pHluorin fluorescence, were all normal in CgA/B-/- neurons. Electron microscopy revealed that synapses contained a normal number of DCVs, with a normal diameter, in CgA/B-/- neurons. In contrast, CgA/B-/- chromaffin cells contained fewer and smaller secretory vesicles with a smaller core size, as previously reported. Finally, live-cell imaging at single vesicle resolution revealed a normal number of fusion events upon bursts of action potentials in CgA/B-/- neurons. These events had normal kinetics and onset relative to the start of stimulation. Taken together, these data indicate that the two chromogranins are dispensable for cargo sorting in the RSP and DCV biogenesis in mouse hippocampal neurons. PMID- 29178419 TI - Understanding aneurysmal type 1 neovascularization (polypoidal choroidal vasculopathy): a lesson in the taxonomy of 'expanded spectra' - a review. AB - The term aneurysmal type 1 neovascularization is derived from terminology, which is established in the literature but has fallen out of use. We believe that aneurysmal type 1 neovascularization accurately describes the lesions which define the entity known as polypoidal choroidal vasculopathy (PCV). Over the last three decades, the clinical spectrum of PCV has expanded to recognize the occurrence of the aneurysmal (polypoidal) lesions in different contexts, resulting in a complex and unwieldy taxonomy based sometimes on circumstantial findings rather than mechanistic considerations. Advances in multimodal imaging provides increasingly convincing evidence that the lesions which define various forms of PCV are indeed vascular and arise from type 1 neovascular networks. The understanding of PCV as type 1 neovascularization with aneurysms renews focus on the question as to why some patients with type 1 neovascularization develop aneurysms while others do not. Conceptual themes and potential for further study are discussed. PMID- 29178420 TI - Drooling is no early sign of dysphagia in Parkinson's disease. AB - BACKGROUND: Dysphagia is frequent and clinically highly relevant in Parkinson's disease (PD). For a rational dysphagia screening predictors are required. Previous investigations suggested that drooling correlates with dysphagia and may serve as its early sign. The aim of this study was to clarify the interrelationship of drooling and dysphagia. METHODS: In a controlled, cross sectional, observational study, a total of 119 Parkinson outpatients and 32 controls were examined clinically and by flexible-endoscopic evaluation of swallowing (FEES). Drooling, dysphagia including retained pharyngeal secretions, and cognitive function were assessed by established evaluation scales. KEY RESULTS: Fifty percent of all PD patients but only 9% of controls had drooling (P < .001). Drooling and dysphagia were related in PD (P = .027) but the data do not support to view drooling as a hallmark symptom for critical dysphagia. Thirty nine percent of the patients with critical aspiration had no drooling. In contrast, 41% of the patients with severe drooling had no clinically relevant dysphagia in FEES. The oral, but not the pharyngeal secretion management was impaired in PD patients and there was no clear association between drooling and pharyngeal secretion accumulation. Cognitive impaired patients had significantly more drooling (P = .005). CONCLUSIONS & INFERENCES: Although frequent in PD, drooling and dysphagia are only weakly related and drooling cannot be viewed as an early sign of dysphagia. Our data further suggest that the underlying cause of drooling is located in the voluntary oral phase, which is negatively influenced by cognitive deficits.

PMID- 29178422 TI - Novel inactivating mutations of the DCAF17 gene in American and Turkish families cause male infertility and female subfertility in the mouse model. AB - Loss-of-function DCAF17 variants cause hypogonadism, partial alopecia, diabetes mellitus, mental retardation, and deafness with variable clinical presentation. DCAF17 pathogenic variants have been largely reported in the Middle Eastern populations, but the incidence in American families is rare and animal models are lacking. Exome sequencing in 5 women with syndromic hypergonadotropic hypogonadism from 2 unrelated families revealed novel pathogenic variants in the DCAF17 gene. DCAF17 exon 2 (c.127-1G > C) novel homozygous variants were discovered in 4 Turkish siblings, while 1 American was compound heterozygous for 1-stop gain variant in exon 5 (c.C535T; p.Gln179*) and previously described stop gain variant in exon 9 (c.G906A; p.Trp302*). A mouse model mimicking loss of function in exon 2 of Dcaf17 was generated using CRISPR/Cas9 and showed female subfertility and male infertility. Our results identify 2 novel variants, and show that Dcaf17 plays a significant role in mammalian gonadal development and infertility.

AB - The incidence of overweight and obesity are increasing with each successive generation of young adults. Associated co-morbidities will emerge at an earlier age unless weight gain is prevented. Evidence has demonstrated young adults (aged 18-35 years) from low socioeconomic and ethnically diverse backgrounds are at greater risk of overweight or obesity, yet it is unclear how to effectively intervene in this population. This systematic review aimed to assess the effectiveness of lifestyle interventions conducted in this population. Thirty studies reporting on lifestyle interventions for prevention of weight gain were identified from eight electronic databases searched. Six interventions included subgroup analyses to determine if ethnicity moderated weight change, and two included subgroup analyses to determine if socioeconomic status had an effect on change in weight. Five of these six studies were effective in preventing weight gain, and subgroup analyses showed no differences in effect by ethnicity. Of these five studies, two included a subgroup analysis that showed socioeconomic status to have no effect on weight outcome. Despite the promising results from these five lifestyle interventions utilizing online and mobile components to effectively reach and prevent weight gain in this priority population, the evidence base of high quality trials is limited.

AB - In electron probe microanalysis, secondary fluorescence can occur leading to an increase of the volume analysed, degrading the lateral resolution of this technique. An adequate knowledge of the interaction volumes from where the different signals of interest are detected is determinant to estimate the minimum size of the zone that can be characterized. In this work, the size of the signal source volume is surveyed for a wide set of samples at different beam energies. To this aim, the PENELOPE software package was chosen to run Monte Carlo simulations for several experimental situations in order to produce the various lateral radiation distributions of interest. A comparison between the interaction volumes of the different signals was performed by taking into account the different fluorescence enhancement possibilities. An unexpected behaviour was found in the particular cases of aluminium and alumina, where the secondary photons signal exhibits a decreasing trend up to certain beam energy (~17 keV); this implies that lower beam energies may degrade the lateral resolution of the technique in these materials.

AB - Research has previously demonstrated that perceptions of peer's teen dating violence (TDV) is associated with one's own perpetration of TDV, although little research has examined whether this relationship is consistent across developmental time periods (i.e., mid-to-late adolescence). The present study examined whether changes in perceptions of peer's TDV predicted change in one's own perpetration of TDV in a sample of ethnically diverse adolescents from ages 15 to 18 (N = 1,042). Parallel process modeling demonstrated that decreases in perceptions of peer's TDV predicted decreases in TDV perpetration over time, and this relationship was more pronounced for males than females. These findings lend further support to the need for TDV prevention and intervention programs to include peer influence in their programs. PMID- 29178426 TI - The role of sentinel lymph node mapping in small animal veterinary medicine: A comparison with current approaches in human medicine. AB - The relevance of regional lymph node (LN) assessment to quantify the metastatic spread of cancer is well recognized in veterinary oncology. Evaluation of LNs is critical for tumour staging. However, sampling the correct LN may not be possible without sentinel lymph node (SLN) mapping. Methods for diagnostic imaging and intraoperative detection of SLNs are well established in human medicine, in particular, the combination of lymphoscintigraphy and intraoperative application of blue dyes. Nevertheless, alternative imaging techniques are available and have gained increasing interest. Successful implementation of these techniques in dogs have been reported in both clinical and experimental studies. This review aims to provide an overview of SLN mapping techniques in human and veterinary medicine.

PMID- 29178427 TI - CD38 modulates respiratory syncytial virus-driven proinflammatory processes in human monocyte-derived dendritic cells. AB - Respiratory syncytial virus (RSV) is the most common cause of hospitalization due to bronchiolitis in infants. Although the mechanisms behind this association are not completely elucidated, they appear to involve an excessive immune response causing lung pathology. Understanding the host response to RSV infection may help in the identification of targets for therapeutic intervention. We infected in vitro human monocyte-derived dendritic cells (DCs) with RSV and analysed various aspects of the cellular response. We found that RSV induces in DCs the expression of CD38, an ectoenzyme that catalyses the synthesis of cyclic ADPR (cADPR). Remarkably, CD38 was under the transcriptional control of RSV-induced type I interferon (IFN). CD38 and a set of IFN-stimulated genes (ISGs) were inhibited by the anti-oxidant N-acetyl cysteine. When CD38-generated cADPR was restrained by 8 Br-cADPR or kuromanin, a flavonoid known to inhibit CD38 enzymatic activity, RSV induced type I/III IFNs and ISGs were markedly reduced. Taken together, these results suggest a key role of CD38 in the regulation of anti-viral responses. Inhibition of CD38 enzymatic activity may represent an encouraging approach to reduce RSV-induced hyperinflammation and a novel therapeutic option to treat bronchiolitis. PMID- 29178429 TI - Technical Note: Defining cyclotron-based clinical scanning proton machines in a FLUKA Monte Carlo system. AB - PURPOSE: Cyclotron-based pencil beam scanning (PBS) proton machines represent nowadays the majority and most affordable choice for proton therapy facilities, however, their representation in Monte Carlo (MC) codes is more complex than passively scattered proton system- or synchrotron-based PBS machines. This is because degraders are used to decrease the energy from the cyclotron maximum energy to the desired energy, resulting in a unique spot size, divergence, and energy spread depending on the amount of degradation. This manuscript outlines a generalized methodology to characterize a cyclotron-based PBS machine in a general-purpose MC code. The code can then be used to generate clinically relevant plans starting from commercial TPS plans. METHODS: The described beam is produced at the Provision Proton Therapy Center (Knoxville, TN, USA) using a cyclotron-based IBA Proteus Plus equipment. We characterized the Provision beam in the MC FLUKA using the experimental commissioning data. The code was then validated using experimental data in water phantoms for single pencil beams and larger irregular fields. Comparisons with RayStation TPS plans are also presented. RESULTS: Comparisons of experimental, simulated, and planned dose depositions in water plans show that same doses are calculated by both programs inside the target areas, while penumbrae differences are found at the field edges. These differences are lower for the MC, with a gamma(3%-3 mm) index never below 95%. CONCLUSIONS: Extensive explanations on how MC codes can be adapted to simulate cyclotron-based scanning proton machines are given with the aim of using the MC as a TPS verification tool to check and improve clinical plans. For all the tested cases, we showed that dose differences with experimental data are lower for the MC than TPS, implying that the created FLUKA beam model is better able to describe the experimental beam. PMID- 29178430 TI - Effects of female sex hormones on folic acid-induced anti-angiogenesis. AB - AIM: Pregnant women have been recommended to take FA daily to prevent birth defects in the brain and spinal cord. We previously showed that folic acid (FA) exerts an anti-angiogenic activity. As angiogenesis is important for endometrial reorganization and embryonic development, there should be some mechanisms to allow the pregnant mother and the foetus to escape from the FA-induced anti angiogenesis. This study was designed to investigate the effect of female sex hormones on the FA-induced anti-angiogenic activity. METHODS: The protein levels and protein-protein interaction were examined by Western blot analysis and immunoprecipitation assay respectively. The cell proliferation and migration were examined by MTT assay and wound healing assay respectively. The in vivo angiogenesis was evaluated by Matrigel angiogenesis assay. RESULTS: In human umbilical venous endothelial cells (HUVEC), FA receptor (FR) formed a complex with progesterone receptor (PR), oestradiol receptor (ER) and cSrc. Pregnancy levels of progesterone (P4) or oestradiol (E2) prevented FA-induced inhibitions of proliferation and migration in HUVEC. Both E2 and P4 prevented the FA-induced anti-angiogenesis in vivo. Moreover, cotreatment with FA and P4 or E2 inhibited the signalling pathways involved in FA-induced inhibitions of proliferation and migration in HUVEC. CONCLUSION: Female sex hormones interrupt the FA-induced anti angiogenic action through receptor-receptor interaction.

AB - The first instance of an acidic aqueous biphasic system (AcABS) based on tributyltetradecyl phosphonium chloride ([P44414 ][Cl]) and an acid is here reported. This AcABS exhibits pronounced thermomorphic behavior and is shown to be applicable to the extraction of metal ions from concentrated acidic solutions. Metal ions such as cobalt(II), iron(III), platinum(IV) and nickel(II) are found to partition preferentially to one of the phases of the acidic aqueous biphasic system and it is here shown that it successfully allows the difficult separation of CoII from NiII , here studied at 24 and 50 degrees C. PMID- 29178432 TI - Acid and Base Resistant Zirconium Polyphenolate-Metalloporphyrin Scaffolds for Efficient CO2 Photoreduction. AB - A series of zirconium polyphenolate-decorated-(metallo)porphyrin metal-organic frameworks (MOFs), ZrPP-n (n = 1, 2), featuring infinite ZrIV -oxo chains linked via polyphenolate groups on four peripheries of eclipse-arranged porphyrin macrocycles, are successfully constructed through a top-down process from simulation to synthesis. These are the unusual examples of Zr-MOFs (or MOFs in general) based on phenolic porphyrins, instead of commonly known carboxylate based types. Representative ZrPP-1 not only exhibits strong acid resistance (pH = 1, HCl) but also remains intact even when immersed in saturated NaOH solution (~20 m), an exceptionally large range of pH resistance among MOFs. The metallation at the porphyrin core gives rise to materials with enhanced sorption and catalytic properties. In particular, ZrPP-1-Co, with precise and uniform distribution of active centers, exhibits not only high CO2 trapping capability (~90 cm3 g-1 at 1 atm, 273 K, among the highest in Zr-MOFs) but also high photocatalytic activity for reduction of CO2 into CO (~14 mmol g-1 h-1 ) and high selectivity over CH4 (>96.4%) without any cocatalyst under visible-light irradiation (lambda > 420 nm). Given the strong chemical resistance under extreme alkali conditions, these catalysts can be recycled without appreciable loss of activity. The possible mechanism for photocatalytic reduction of CO2 -to-CO over ZrPP-1-Co is also proposed. PMID- 29178433 TI - Triptolide inhibits donor-specific antibody production and attenuates mixed antibody-mediated renal allograft injury. AB - Donor-specific antibodies (DSAs) are major mediators of renal allograft injury, and strategies to inhibit DSAs are important in promoting long-term graft survival. Triptolide exhibits a wide spectrum of antiinflammatory and immunosuppressive activities, and in autoimmune diseases it inhibits autoantibody levels. In this study, we investigated the suppressive role of triptolide in the generation of DSAs in transplant recipients. We found that triptolide treatment of skin allograft recipients in mice significantly suppressed the development of circulating anti-donor-specific IgG and effectively alleviated DSA-mediated renal allograft injury, which led to prolonged allograft survival. In vitro studies revealed that triptolide inhibited the differentiation of B cells into CD138+ CD27++ plasma cells; reduced the levels of IgA, IgG, and IgM secreted by plasma cells; and repressed somatic hypermutation and class switch recombination of B cells. Moreover, triptolide-treated recipients showed reduced numbers of B cells, plasma cells, and memory B cells in spleens and decreased numbers of T, B, natural killer (NK) cells, and macrophages infiltrating grafts. These findings highlight the importance of triptolide in suppressing DSAs and establish triptolide as a novel therapeutic agent for antibody-mediated allograft rejection. PMID- 29178434 TI - Demonstration of an anti-hyperalgesic effect of a novel pan-Trk inhibitor PF 06273340 in a battery of human evoked pain models. AB - AIM: Inhibitors of nerve growth factor (NGF) reduce pain in several chronic pain indications. NGF signals through tyrosine kinase receptors of the tropomyosin related kinase (Trk) family and the unrelated p75 receptor. PF-06273340 is a small molecule inhibitor of Trks A, B and C that reduces pain in nonclinical models, and the present study aimed to investigate the pharmacodynamics of this first-in-class molecule in humans. METHODS: A randomized, double-blind, single dose, placebo- and active-controlled five-period crossover study was conducted in healthy human subjects (NCT02260947). Subjects received five treatments: PF 06273340 50 mg, PF-06273340 400 mg, pregabalin 300 mg, ibuprofen 600 mg and placebo. The five primary endpoints were the pain detection threshold for the thermal pain tests and the pain tolerance threshold for the cold pressor, electrical stair and pressure pain tests. The trial had predefined decision rules based on 95% confidence that the PF-06273340 effect was better than that of placebo. RESULTS: Twenty subjects entered the study, with 18 completing all five periods. The high dose of PF-06273340 met the decision rules on the ultraviolet (UV) B skin thermal pain endpoint [least squares (LS) mean vs. placebo: 1.13, 95% confidence interval: 0.64-1.61], but not on the other four primary endpoints. The low dose did not meet the decision criteria for any of the five primary endpoints. Pregabalin (cold pressor and electrical stair tests) and ibuprofen (UVB thermal pain) showed significant analgesic effects on expected endpoints. CONCLUSIONS: The study demonstrated, for the first time, the translation of nonclinical effects into man in an inflammatory pain analgesic pharmacodynamic endpoint using a pan-Trk inhibitor. PMID- 29178435 TI - In Vivo Therapeutic Effect of Vaccinium Meridionale Swartz in Ischemia Reperfusion Induced Male Albino Rats. AB - This study was aimed to investigate the cardioprotective and antioxidant effect of Vaccinium meridionale Swartz in ischemia-induced male albino Wistar strain rats. Rats were grouped into 5 of 6 numbers each. Group I served as a sham, group II served as control and group III, IV, and V served for 1, 10, and 25 mg/kg/d of an extract of Vaccinium meridionale Swartz for 15 consecutive days of treatment. Serum marker enzymes, lipid peroxidation, and myeloperoxidase were increased, whereas antioxidant enzymes were reduced in control due to injury. Increased phenol and anthocyanin contents and increased free radical scavenging activity was noted following treatment. Serum marker enzymes, necrosis, and lipid peroxidation, were reduced, whereas antioxidant enzymes and reduced glutathione were increased. Nitric oxide synthase and Akt expression were also increased following treatment. Taking all these data together, it is suggested that Vaccinium meridionale Swartz may be a potential therapeutic agent for the treatment of ischemic injury. PMID- 29178436 TI - Incremental Treatment Costs Attributable to Overweight and Obesity in Patients with Diabetes: Quantile Regression Approach. AB - OBJECTIVE: This study aimed to estimate treatment costs attributable to overweight and obesity in patients with diabetes who were less than 65 years of age in the United States. METHODS: This study used data from the Medical Expenditure Panel Survey from 2001 to 2013. Patients with diabetes were identified by using the International Classification of Diseases, Ninth Revision, Clinical Modification code (250), clinical classification codes (049 and 050), or self-reported physician diagnoses. Total treatment costs attributable to overweight and obesity were calculated as the differences in the adjusted costs compared with individuals with diabetes and normal weight. Adjusted costs were estimated by using generalized linear models or unconditional quantile regression models. RESULTS: The mean annual treatment costs attributable to obesity were $1,852 higher than those attributable to normal weight, while costs attributable to overweight were $133 higher. The unconditional quantile regression results indicated that the impact of obesity on total treatment costs gradually became more significant as treatment costs approached the upper quantile. CONCLUSIONS: Among patients with diabetes who were less than 65 years of age, patients with diabetes and obesity have significantly higher treatment costs than patients with diabetes and normal weight. The economic burden of diabetes to society will continue to increase unless more proactive preventive measures are taken to effectively treat patients with overweight or obesity. PMID- 29178437 TI - Skin color and tissue thickness effects on transmittance, reflectance, and skin temperature when using 635 and 808 nm lasers in low intensity therapeutics. AB - OBJECTIVE: To examine the role of skin color and tissue thickness on transmittance, reflectance, and skin heating using red and infrared laser light. METHODS: Forty volunteers were measured for skin color and skin-fold thickness at a standardized site near the elbow. Transmittance, reflectance and skin temperature were recorded for energy doses of 2, 6, 9, and 12 Joules using 635 nm (36 mW) and 808 nm (40 mW) wavelength laser diodes with irradiances within American National Standards Institute safety guidelines (4.88 mm diameter, 0.192 W/cm2 and 4.88 mm diameter, 0.214 W/cm2 , respectively). RESULTS: The key factors affecting reflectance to an important degree were skin color and wavelength. However, the skin color effects were different for the two wavelengths: reflectance decreased for darker skin with a greater decrease for red light than near infrared light. Transmittance was greater using 808 nm compared with 635 nm. However, the effect was partly lost when the skin was dark rather than light, and was increasingly lost as tissue thickness increased. Dose had an increasing effect on temperature (0.7-1.6 degrees C across the 6, 9, and 12 J doses); any effects of wavelength, skin color, and tissue thickness were insignificant compared to dose effects. Subjects themselves were not aware of the increased skin temperature. Transmittance and reflectance changes as a function of energy were very small and likely of no clinical significance. Absorption did not change with higher energy doses and increasing temperature. CONCLUSION: Skin color and skin thickness affect transmittance and reflectance of laser light and must be accounted for when selecting energy dose to ensure therapeutic effectiveness at the target tissue. Skin heating appears not to be a concern when using 635 and 808 nm lasers at energy doses of up to 12 J and irradiance within American National Standards Institute standards. Photobiomodulation therapy should never exceed the American National Standards Institute recommendation for the maximum permissible exposure to the skin. Lasers Surg. Med. 50:291-301, 2018.

AB - Jejunoileal diverticulosis (JID) is a rare condition with a reported incidence lower than 0.1% (1-3). Surgery is the definitive treatment for JID and can be considered to improve the patient's quality of life and to prevent further occurrence of severe symptoms (3, 4, 5). Minimally invasive approach facilitates postoperative recovery, lowers risks and improves outcomes in JID treatment (6). This article is protected by copyright. All rights reserved. PMID- 29178439 TI - Renal parenchyma impairment characterization in partial unilateral ureteral obstruction in mice with intravoxel incoherent motion-MRI. AB - Ureteropelvic junction obstruction constitutes a major cause of progressive pediatric renal disease. The biological mechanisms underlying the renal response to obstruction can be investigated using a clinically relevant mouse model of partial unilateral ureteral obstruction (pUUO). Renal function and kidney morphology data can be evaluated using renal ultrasound, scintigraphy and uro magnetic resonance imaging (uro-MRI), but these methods are poorly linked to histological change and not all are quantitative. Here, we propose to investigate pUUO for the first time using an intravoxel incoherent motion diffusion sequence. The aim of this study was to quantitatively characterize impairment of the kidney parenchyma in the pUUO model. This quantitative MRI method was able to assess the perfusion and microstructure of the kidney without requiring the injection of a contrast agent. The results suggest that a perfusion fraction (f) reduction is associated with a decrease in the volume of the renal parenchyma, which could be related to decreased renal vascularization. The latter may occur before impairment by fibrosis and the findings are in accordance with the literature using the UUO mice model and, more specifically, on pUUO. Further investigation is required before this technique can be made available for the diagnosis and management of children with antenatal hydronephrosis and to select the optimal timing of surgery if required. PMID- 29178440 TI - Invisible detergents for structure determination of membrane proteins by small angle neutron scattering. AB - A novel and generally applicable method for determining structures of membrane proteins in solution via small-angle neutron scattering (SANS) is presented. Common detergents for solubilizing membrane proteins were synthesized in isotope substituted versions for utilizing the intrinsic neutron scattering length difference between hydrogen and deuterium. Individual hydrogen/deuterium levels of the detergent head and tail groups were achieved such that the formed micelles became effectively invisible in heavy water (D2 O) when investigated by neutrons. This way, only the signal from the membrane protein remained in the SANS data. We demonstrate that the method is not only generally applicable on five very different membrane proteins but also reveals subtle structural details about the sarco/endoplasmatic reticulum Ca2+ ATPase (SERCA). In all, the synthesis of isotope-substituted detergents makes solution structure determination of membrane proteins by SANS and subsequent data analysis available to nonspecialists. PMID- 29178441 TI - Gene-based genetic association test with adaptive optimal weights. AB - It is well known that using proper weights for genetic variants is crucial in enhancing the power of gene- or pathway-based association tests. To increase the power, we propose a general approach that adaptively selects weights among a class of weight families and apply it to the popular sequencing kernel association test. Through comprehensive simulation studies, we demonstrate that the proposed method can substantially increase power under some conditions. Applications to real data are also presented. This general approach can be extended to all current set-based rare variant association tests whose performances depend on variant's weight assignment. PMID- 29178442 TI - The Effect of Food or Omeprazole on the Pharmacokinetics of Osimertinib in Patients With Non-Small-Cell Lung Cancer and in Healthy Volunteers. AB - Two phase 1, open-label studies assessed the impact of food or gastric pH modification (omeprazole) on the exposure and safety/tolerability of osimertinib and its metabolites. The food effect study was an open-label, 2-period crossover study in patients with advanced non-small-cell lung cancer, randomized into 2 treatment sequences: single-dose osimertinib 80 mg in a fed then fasted state or fasted then fed. The gastric pH study was an open-label, 2-period fixed sequence study assessing the effect of omeprazole on osimertinib exposure in healthy male volunteers. In period 1, volunteers received omeprazole 40 mg (days 1-4), then omeprazole 40 mg plus osimertinib 80 mg (day 5). In period 2, volunteers received osimertinib 80 mg alone (single dose). Blood samples were collected at prespecified time points for pharmacokinetic analyses. Safety/tolerability was also assessed. In the food effect study 38 patients were randomized to fed/fasted (n = 18) or fasted/fed (n = 20) sequences with all patients completing treatment. Coadministration with food did not affect osimertinib exposure (geometric least squares mean ratios [90% confidence intervals]: 106.05% [94.82%, 118.60%] [area under the plasma concentration time curve from zero to 72 hours] and 92.75% [81.40%, 105.68%] [maximum plasma concentration]). In the gastric pH study (n = 68 received treatment, n = 47 completed the study), coadministration with omeprazole did not affect osimertinib exposure (geometric least-squares mean ratios 106.66% [100.26%, 113.46%] [area under the concentration-time curve], 101.65% [94.65%, 109.16%] [peak concentration]). Osimertinib was well tolerated in both studies. Osimertinib may be administered without regard to food. Dose restriction is not required in patients whose gastric pH may be altered by concomitant agents or medical conditions. ClinicalTrials.gov: NCT02224053, NCT02163733. PMID- 29178444 TI - Alemtuzumab versus interferon beta 1a for relapsing-remitting multiple sclerosis. AB - BACKGROUND: Alemtuzumab is a humanised monoclonal antibody that alters the circulating lymphocyte pool, causing prolonged lymphopenia, thus remoulding the immune repertoire that accompanies homeostatic lymphocyte reconstitution. It has been proved more effective than interferon (IFN) 1a for the treatment of relapsing-remitting multiple sclerosis (RRMS). OBJECTIVES: To compare the efficacy, tolerability and safety of alemtuzumab versus interferon beta 1a in the treatment of people with RRMS to prevent disease activity. SEARCH METHODS: We searched the Cochrane Multiple Sclerosis and Rare Diseases of the CNS Group Trials Register (1 February 2017) which, among other sources, contains records from CENTRAL, MEDLINE, Embase, CINAHL, LILACS, PEDRO and the trial registry databases Clinical Trials.gov and WHO International Clinical Trials Registry Platform for all prospectively registered and ongoing trials. SELECTION CRITERIA: All double-blind, randomised, controlled trials comparing intravenous alemtuzumab (12 mg per day or 24 mg per day on five consecutive days during the first month and on three consecutive days at months 12 and 24) versus subcutaneous IFN beta 1a (22 MUg or 44 MUg three times per week (Rebif) or intramuscular injection 30 MUg once a week (Avonex)) in people of any gender and age with RRMS. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included three trials involving 1694 participants. All trials compared alemtuzumab 12 mg per day or 24 mg per day versus IFN beta 1a for treating RRMS. In CAMMS223, participants received either subcutaneous IFN beta 1a 44 MUg three times per week or annual intravenous cycles of alemtuzumab (at a dose of 12 mg per day or 24 mg per day) for 36 months. In CARE-MS I and CARE-MS II, participants received subcutaneous IFN beta 1a 44 MUg three times per week or annual intravenous cycles of alemtuzumab 12 mg per day for 24 months. The methodological quality was good for all three studies.In the alemtuzumab 12 mg per day group, the results showed statistically significant difference in reducing relapses (risk ratio (RR) 0.60, 95% confidence interval (CI) 0.52 to 0.70), preventing disease progression (RR 0.60, 95% CI 0.45 to 0.79) and developing new T2 lesions on magnetic resonance imaging (RR 0.75, 95% CI 0.61 to 0.93) after 24 and 36 months' follow-up, but found no statistically significant difference in the changes of Expanded Disability Status Scale (EDSS) score (mean difference (MD) -0.35, 95% CI -0.73 to 0.03). In the alemtuzumab 24 mg per day group, the results showed statistically significant differences in reducing relapses (RR 0.38, 95% CI 0.23 to 0.62), preventing disease progression (RR 0.42, 95% CI 0.21 to 0.84) and the changes of EDSS score (MD -0.83, 95% CI -1.17 to 0.49) after 36 months' follow-up.All three trials reported adverse events and serious adverse events. There was no statistically significant difference in the number of participants with at least one adverse event (RR 1.03, 95% CI 0.97 to 1.08) and the number of participants who experienced serious adverse events (RR 1.03, 95% CI 0.83 to 4.54). AUTHORS' CONCLUSIONS: There is low- to moderate quality evidence that annual intravenous cycles of alemtuzumab at a dose of 12 mg per day or 24 mg per day reduces the proportion of participants with relapses, disease progression, change of EDSS score and developing new T2 lesions on MRI over 24 to 36 months in comparison with subcutaneous IFN beta-1a 44 MUg three times per week.Alemtuzumab appeared to be relatively well tolerated. The most frequently reported adverse events were infusion-associated reactions, infections and autoimmune events. The use of alemtuzumab requires careful monitoring so that potentially serious adverse effects can be treated early and effectively. PMID- 29178445 TI - Pleistocene climatic changes drive diversification across a tropical savanna. AB - Spatial responses of species to past climate change depend on both intrinsic traits (climatic niche breadth, dispersal rates) and the scale of climatic fluctuations across the landscape. New capabilities in generating and analysing population genomic data, along with spatial modelling, have unleashed our capacity to infer how past climate changes have shaped populations, and by extension, complex communities. Combining these approaches, we uncover lineage diversity across four codistributed lizards from the Australian Monsoonal Tropics and explore how varying climatic tolerances interact with regional climate history to generate common vs. disparate responses to late Pleistocene change. We find more divergent spatial structuring and temporal demographic responses in the drier Kimberley region compared to the more mesic and consistently suitable Top End. We hypothesize that, in general, the effects of species' traits on sensitivity to climate fluctuation will be more evident in climatically marginal regions. If true, this points to the need in climatically marginal areas to craft more species-(or trait)-specific strategies for persistence under future climate change. PMID- 29178446 TI - Experimental and Theoretical Study of Enhanced Photocatalytic Activity of Mg Doped ZnO NPs and ZnO/rGO Nanocomposites. AB - A systematic experimental and theoretical study of the origin of the enhanced photocatalytic performance of Mg-doped ZnO nanoparticles (NPs) and Mg-doped ZnO/reduced graphene oxide (rGO) nanocomposites has been performed. In addition to Mg, Cd was chosen as a doping material for the bandgap engineering of ZnO NPs, and its effects were compared with that of Mg in the photocatalytic performance of ZnO nanostructures. The experimental results revealed that Mg, as a doping material, recognizably ameliorates the photocatalytic performance of ZnO NPs and ZnO/graphene nanocomposites. Transmission electron microscopy (TEM) images showed that the Mg-doped and Cd-doped ZnO NPs had the same size. The optical properties of the samples indicated that Cd narrowed the bandgap, whereas Mg widened the bandgap of the ZnO NPs and the oxygen vacancy concentration was similar for both samples. Based on the experimental results, the narrowing of the bandgap, the particle size, and the oxygen vacancy did not enhance the photocatalytic performance. However, Brunauer-Emmett-Teller (BET) and Barret-Joyner-Halenda (BJH) models showed that Mg caused increased textural properties of the samples, whereas rGO played an opposite role. A theoretical study, conducted by using DFT methods, showed that the improvement in the photocatalytic performance of Mg doped ZnO NPs was due to a higher electron transfer from the Mg-doped ZnO NPs to the dye molecules compared with pristine ZnO and Cd-doped ZnO NPs. Moreover, according to the experimental results, along with Mg, graphene also played an important role in the photocatalytic performance of ZnO. PMID- 29178443 TI - Review: The past, present and future challenges in epilepsy-related and sudden deaths and biobanking. AB - Awareness and research on epilepsy-related deaths (ERD), in particular Sudden Unexpected Death in Epilepsy (SUDEP), have exponentially increased over the last two decades. Most publications have focused on guidelines that inform clinicians dealing with these deaths, educating patients, potential risk factors and mechanisms. There is a relative paucity of information available for pathologists who conduct these autopsies regarding appropriate post mortem practice and investigations. As we move from recognizing SUDEP as the most common form of ERD toward in-depth investigations into its causes and prevention, health professionals involved with these autopsies and post mortem procedure must remain fully informed. Systematizing a more comprehensive and consistent practice of examining these cases will facilitate (i) more precise determination of cause of death, (ii) identification of SUDEP for improved epidemiological surveillance (the first step for an intervention study), and (iii) biobanking and cell-based research. This article reviews how pathologists and healthcare professionals have approached ERD, current practices, logistical problems and areas to improve and harmonize. The main neuropathology, cardiac and genetic findings in SUDEP are outlined, providing a framework for best practices, integration of clinical, pathological and molecular genetic investigations in SUDEP, and ultimately prevention. PMID- 29178448 TI - Expanding the Clinical Spectrum of Phenotypes Caused by Pathogenic Variants in PLOD2. AB - Osteogenesis imperfecta (OI) is a strikingly heterogeneous group of disorders with a broad range of phenotypic variations. It is also one of the differential diagnoses in bent bone dysplasias along with campomelic dysplasia and thanatophoric dysplasia and can usually be distinguished by decreased bone mineralization and bone fractures. Bent bone dysplasias also include syndromes such as kyphomelic dysplasia (MIM:211350) and mesomelic dysplasia Kozlowski Reardon (MIM249710), both of which have been under debate regarding whether or not they are a real entity or simply a phenotypic manifestation of another dysplasia including OI. Bruck syndrome type 2 (BRKS2; MIM:609220) is a rare form of autosomal recessive OI caused by biallelic PLOD2 variants and is associated with congenital joint contractures with pterygia. In this report, we present six patients from four families with novel PLOD2 variants. All cases had multiple fractures. Other features ranged from prenatal lethal severe angulation of the long bones as in kyphomelic dysplasia and mesomelic dysplasia Kozlowski-Reardon through classical Bruck syndrome to moderate OI with normal joints. Two siblings with a kyphomelic dysplasia-like phenotype who were stillborn had compound heterozygous variants in PLOD2 (p.Asp585Val and p.Ser166*). One infant who succumbed at age 4 months had a bent bone phenotype phenotypically like skeletal dysplasia Kozlowski-Reardon (with mesomelic shortening, camptodactyly, retrognathia, cleft palate, skin dimples, but also with fractures). He was homozygous for the nonsense variant (p.Trp561*). Two siblings had various degrees of Bruck syndrome caused by the homozygous missense variant, p.His687Arg. Furthermore a boy with a clinical presentation of moderate OI had a possibly pathogenic homozygous variant p.Trp588Cys. Our experience of six patients with biallelic pathogenic variants in PLOD2 expands the phenotypic spectrum in the PLOD2-related phenotypes. (c) 2017 American Society for Bone and Mineral Research.

AB - CHARGE syndrome (CS) is a genetic disorder whose first description included Coloboma, Heart disease, Atresia of choanae, Retarded growth and development, Genital hypoplasia, and Ear anomalies and deafness, most often caused by a genetic mutation in the CHD7 gene. Two features were then added: semicircular canal anomalies and arhinencephaly/olfactory bulb agenesis, with classification of typical, partial, or atypical forms on the basis of major and minor clinical criteria. The detection rate of a pathogenic variant in the CHD7 gene varies from 67% to 90%. To try to have an overview of this heterogenous clinical condition and specify a genotype-phenotype relation, we conducted a national study of phenotype and genotype in 119 patients with CS. Selected clinical diagnostic criteria were from Verloes (2005), updated by Blake & Prasad (). Besides obtaining a detailed clinical description, when possible, patients underwent a full ophthalmologic examination, audiometry, temporal bone CT scan, gonadotropin analysis, and olfactory-bulb MRI. All patients underwent CHD7 sequencing and MLPA analysis. We found a pathogenic CHD7 variant in 83% of typical CS cases and 58% of atypical cases. Pathogenic variants in the CHD7 gene were classified by the expected impact on the protein. In all, 90% of patients had a typical form of CS and 10% an atypical form. The most frequent features were deafness/semicircular canal hypoplasia (94%), pituitary defect/hypogonadism (89%), external ear anomalies (87%), square-shaped face (81%), and arhinencephaly/anosmia (80%). Coloboma (73%), heart defects (65%), and choanal atresia (43%) were less frequent. PMID- 29178450 TI - Generic approach to the method development of intact protein separations using hydrophobic interaction chromatography. AB - We describe a liquid chromatography method development approach for the separation of intact proteins using hydrophobic interaction chromatography. First, protein retention was determined as function of the salt concentration by isocratic measurements and modeled using linear regression. The error between measured and predicted retention factors was studied while varying gradient time (between 15 and 120 min) and gradient starting conditions, and ranged between 2 and 15%. To reduce the time needed to develop optimized gradient methods for hydrophobic interaction chromatography separations, retention-time estimations were also assessed based on two gradient scouting runs, resulting in significantly improved retention-time predictions (average error < 2.5%) when varying gradient time. When starting the scouting gradient at lower salt concentrations (stronger eluent), retention time prediction became inaccurate in contrast to predictions based on isocratic runs. Application of three scouting runs and a nonlinear model, incorporating the effects of gradient duration and mobile-phase composition at the start of the gradient, provides accurate results (improved fitting compared to the linear solvent-strength model) with an average error of 1.0% and maximum deviation of -8.3%. Finally, gradient scouting runs and retention-time modeling have been applied for the optimization of a critical-pair protein isoform separation encountered in a biotechnological sample.

AB - There is little known about sexual offenders hospitalized under forensic commitment statutes such as not guilty by reason of insanity (NGRI). We conducted a chart review to delineate the demographic, clinical, and legal characteristics of NGRI sexual offenders (n = 68) committed to the California Department of State Hospitals-Napa, including 41 found NGRI for a sexual offense and 27 found NGRI for a nonsexual offense. The two groups did not differ significantly in their demographics, psychiatric diagnoses, victim characteristics, or recidivism risk as measured by the Static-99R. Those found NGRI for a sexual offense were older at the time of their first criminal and first violent offense, younger at the time of their committing offense, and had fewer prior total convictions and sexual offense convictions. These findings may indicate that sexual offenders found NGRI for a sexual offense are less antisocial than those found NGRI for a nonsexual offense.

AB - Genome-wide association studies (GWAS) are now routinely imputed for untyped single nucleotide polymorphisms (SNPs) based on various powerful statistical algorithms for imputation trained on reference datasets. The use of predicted allele counts for imputed SNPs as the dosage variable is known to produce valid score test for genetic association. In this paper, we investigate how to best handle imputed SNPs in various modern complex tests for genetic associations incorporating gene-environment interactions. We focus on case-control association studies where inference for an underlying logistic regression model can be performed using alternative methods that rely on varying degree on an assumption of gene-environment independence in the underlying population. As increasingly large-scale GWAS are being performed through consortia effort where it is preferable to share only summary-level information across studies, we also describe simple mechanisms for implementing score tests based on standard meta analysis of "one-step" maximum-likelihood estimates across studies. Applications of the methods in simulation studies and a dataset from GWAS of lung cancer illustrate ability of the proposed methods to maintain type-I error rates for the underlying testing procedures. For analysis of imputed SNPs, similar to typed SNPs, the retrospective methods can lead to considerable efficiency gain for modeling of gene-environment interactions under the assumption of gene environment independence. Methods are made available for public use through CGEN R software package.

AB - AIMS/INTRODUCTION: Member B of the family with sequence similarity 3 (FAM3B), also known as pancreatic-derived factor, is mainly synthesized and secreted by islet beta-cells, and plays a role in abnormal metabolism of glucose and lipids. However, the prospective association of FAM3B with metabolic disorders remains unclear. The present study aimed to reveal the predictive relationship between pancreas-specific cytokine and metabolic syndrome (MetS). MATERIALS AND METHODS: A total of 210 adults (88 men and 122 women) without MetS, aged between 40 and 65 years, were recruited and received a comprehensive health examination. Baseline serum FAM3B levels were determined by sandwich enzyme-linked immunosorbent assay. Subsequently, all participants underwent a follow-up examination after 5 years. MetS was identified in accordance with the International Diabetes Federation criteria. RESULTS: During follow up, 35.7% participants developed MetS. In comparison with the non-MetS group, participants with MetS had an increased serum FAM3B at baseline (21.85 ng/mL [19.38, 24.17 ng/mL] vs 28.56 ng/mL [25.32, 38.10 ng/mL], P < 0.001). Moreover, serum FAM3B was significantly associated with variations in fasting plasma insulin (r = -0.306, P < 0.001), homeostasis model assessment of beta-cell function (r = -0.328, P < 0.001) and homeostasis model assessment of insulin resistance (r = -0.191, P = 0.006). Furthermore, a positive correlation between baseline FAM3B and the incidence of MetS was observed, even after multivariable adjustment (relative risk 1.23 [1.15, 1.31], P < 0.001). Furthermore, the optimal cut-off values of FAM3B was 23.98 ng/mL for predicting MetS based on the Youden Index. CONCLUSIONS: Elevated circulating FAM3B might be considered as a predictor of newly-onset MetS and its progression.

AB - A new silver-functionalized silica-based material with a core-shell structure based on silver nanoparticle-coated silica spheres was synthesized, and silver nanoparticles were modified using strongly bound l-cysteine. l-Cysteine silver@silica was characterized by scanning electron microscopy and FTIR spectroscopy. Then, a solid-phase extraction method based on l-cysteine silver@silica was developed and successfully used for bisphenol A determination prior to HPLC analysis. The results showed that the l-cysteine-silver@silica as an adsorbent exhibited good enrichment capability for bisphenol A, and the maximum adsorption saturation was 20.93 mg/g. Moreover, a short adsorption equilibrium time was obtained due to the presence of silver nanoparticles on the surface of the silica. The extraction efficiencies were then optimized by varying the eluents and pH. Under the optimized conditions, good linearity for bisphenol A was obtained in the range from 0.4 to 4.0 MUM (R2 > 0.99) with a low limit of detection (1.15 ng/mL). The spiked recoveries from tap water and milk samples were satisfactory (85-102%) with relative standard deviations below 5.2% (n = 3), which indicated that the method was suitable for the analysis of bisphenol A in complex samples.

AB - Social media, with its capabilities of fast, global information sharing, provides a useful medium for professional development, connecting and collaborating with peers, and outreach. The goals of this study were to describe a new, sustainable model for Twitter use by professional societies, and analyze its impact on @AACAnatomy, the Twitter account of the American Association of Clinical Anatomists. Under supervision of an Association committee member, an anatomy graduate student developed a protocol for publishing daily tweets for @AACAnatomy. Five tweet categories were used: Research, Announcements, Replies, Engagement, and Community. Analytics from the 6-month pilot phase were used to assess the impact of the new model. @AACAnatomy had a steady average growth of 33 new followers per month, with less than 10% likely representing Association members. Research tweets, based on Clinical Anatomy articles with an abstract link, were the most shared, averaging 5,451 impressions, 31 link clicks, and nine #ClinAnat hashtag clicks per month. However, tweets from non-Research categories accounted for the highest impression and engagement metrics in four out of six months. For all tweet categories, monthly averages show consistent interaction of followers with the account. Daily tweet publication resulted in a 103% follower increase. An active Twitter account successfully facilitated regular engagement with @AACAnatomy followers and the promotion of clinical anatomy topics within a broad community. This Twitter model has the potential for implementation by other societies as a sustainable medium for outreach, networking, collaboration, and member engagement. Clin. Anat. 31:566-575, 2018.

AB - OBJECTIVES: To test whether maternal education has a direct effect on gingival bleeding in adolescents aged 12 and to assess whether oral health behaviours over time mediate that association. METHODS: Two oral health studies nested in the 1993 Pelotas (Brazil) birth cohort study were carried out in participants aged 6 (n = 359) and 12 years (n = 339). The proportion of teeth with bleeding on probing (BOP) and the median number of teeth with gingivitis at age 12 were recorded. Maternal education at birth was the exposure. Toothbrushing frequency and dental visit at ages 6 and 12 years were investigated as mediators of the association between maternal education at birth and gingival bleeding. Time varying family income through childhood and adolescence was included as later confounder. Paternal education was taken as baseline confounder. The controlled direct effect (CDE) of maternal education at child's birth on gingival bleeding at age 12 was estimated using marginal structural models (MSM). Additionally, path analysis was employed to estimate standardized direct, indirect and total effects of maternal education at birth on gingival bleeding. RESULTS: Adjusted analyses using MSM showed that adolescents whose mothers had <8 years of education had 3.82 higher risk of having teeth with gingival bleeding above the median (rate ratio RR 3.82; 95% CI: 1.68-8.19). Low maternal education doubled the proportion of gingival bleeding at age 12 not mediated by dental visit and toothbrushing frequency (RR 1.99; 95% CI: 1.52-2.60). Path analysis revealed that maternal education had a direct effect on gingival bleeding independently of the mediators. CONCLUSIONS: The pattern of oral health behaviours does not explain the association between mother's education and adolescent's gingival bleeding. Individual-based approaches focused on oral health-related behaviours tend to fail to prevent gingival bleeding. PMID- 29178457 TI - Relative dosimetry with an MR-linac: Response of ion chambers, diamond, and diode detectors for off-axis, depth dose, and output factor measurements. AB - PURPOSE: The purpose of this study was to acquire beam data for an MR-linac, with and without a 1.5 T magnetic field, by using a variety of commercially available detectors to assess their relative response in the magnetic field. The impact of the magnetic field on the measured dose distribution was also assessed. METHODS: An MR-safe 3D scanning water phantom was used to measure output factors, depth dose curves, and off-axis profiles for various depths and for field sizes between 2 * 2 cm2 and 22 * 22 cm2 for an Elekta MR-linac beam with the orthogonal 1.5 T magnetic field on or off. An on-board MV portal imaging system was used to ensure that the reproducibility of the detector position, both with and without the magnetic field, was within 0.1 mm. The detectors used included ionization chambers with large, medium, and small sensitive volumes; a diamond detector; a shielded diode; and an unshielded diode. RESULTS: The offset of the effective point of measurement of the ionization chambers was found to be reduced by at least half for each chamber in the direction parallel with the beam. A lateral shift of similar magnitude was also introduced to the chambers' effective point of measurement toward the average direction of the Lorentz force. A similar lateral shift (but in the opposite direction) was also observed for the diamond and diode detectors. The measured lateral shift in the dose distribution was independent of depth and field size for each detector for fields between 2 * 2 cm2 and 10 * 10 cm2 . The shielded diode significantly misrepresented the dose distribution in the lateral direction perpendicular to the magnetic field, making it seem more symmetric. The percentage depth dose was generally found to be lower with the magnetic field than without, but this difference was reduced as field size increased. The depth of maximum dose showed little dependence on field size in the presence of the magnetic field, with values from 1.2 cm to 1.3 cm between the 2 * 2 cm2 and 22 * 22 cm2 fields. Output factors measured in the magnetic field at the center of the beam profile produced a larger spread of values between detectors for fields smaller than 10 * 10 cm2 (with a spread of 2% at 3 * 3 cm2 ). The spread of values was more consistent when the output factors were measured at the point of peak intensity of the lateral dose distribution instead (except for the shielded diode which differed by up to 2% depending on field size). CONCLUSIONS: The magnetic field of the MR-linac alters the effective point of measurement of ionization chambers, shifting it both downstream and laterally. Shielded diodes produce incorrect and misleading dose profiles. The output factor measured at the point of peak intensity in the lateral dose distribution is more robust than the conventional output factor (measured at central axis). Diodes are not recommended for output factor measurements in the magnetic field. PMID- 29178459 TI - Inflammatory and metabolic responses to an intramammary lipopolysaccharide challenge in early lactating cows supplemented with conjugated linoleic acid. AB - Supplementation of dairy cows with trans-10, cis-12 conjugated linoleic acid (CLA) allows nutrient repartitioning despite an energy deficiency in early lactation, which might be a benefit for the immune system, too. In this study, we investigated potential nutrient sparing effects of CLA in early lactating cows with low plasma glucose concentrations exposed to an intramammary lipopolysaccharide (LPS) challenge. Fifteen multiparous Holstein cows were exposed to an intramammary LPS challenge in week 4 p.p. Eight cows (CLA) were supplemented daily with 70 g of lipid-encapsulated CLA (6.8 g trans-10, cis-12 and 6.6 g of the cis-9, trans-11 CLA isomer; CLA) and seven cows with 56 g of control fat (CON). Blood samples were obtained every 30 min along with rectal temperature, heart and respiratory rate, and milk samples were taken hourly until 10 hr after the LPS application. Plasma was analysed for concentrations of glucose, free fatty acids, beta-hydroxybutyrate (BHB), cortisol, insulin and glucagon. In milk, somatic cell count and activity of lactate dehydrogenase were determined. Initial plasma glucose concentration was lower in CLA than in CON. During the immunostimulation, CLA had higher glucose concentrations than CON, and BHB decreased distinctly in CLA, whereas CON cows maintained BHB concentration at a lower level. Body temperature in CLA increased earlier, the difference between peak and basal temperature was higher, and the decline thereafter occurred earlier. In conclusion, CLA supplementation of early lactating cows exposed to an intramammary LPS challenge affected local and systemic immune responses. We assume that CLA supplementation triggered glycogen storage. Cows supplemented with CLA provided more glucose and preferentially used BHB as an energy source during the immune response. The more intense metabolic and more concentrated endocrine responses support an immunomodulatory effect of CLA supplementation. PMID- 29178458 TI - Impairment of Bone Remodeling in LIGHT/TNFSF14-Deficient Mice. AB - Multiple cytokines produced by immune cells induce remodeling and aid in maintaining bone homeostasis through differentiation of bone-forming osteoblasts and bone-resorbing osteoclasts. Here, we investigate bone remodeling controlled by the tumor necrosis factor (TNF) superfamily cytokine LIGHT. LIGHT-deficient mice (Tnfsf14-/- ) exhibit spine deformity and reduced femoral cancellous bone mass associated with an increase in the osteoclast number and a slight decrease of osteoblasts compared with WT mice. The effect of LIGHT in bone cells can be direct or indirect, mediated by both the low expression of the anti osteoclastogenic osteoprotegerin (OPG) in B and T cells and reduced levels of the pro-osteoblastogenic Wnt10b in CD8+ T cells in Tnfsf14-/- mice. LIGHT stimulation increases OPG levels in B, CD8+ T, and osteoblastic cells, as well as Wnt10b expression in CD8+ T cells. The high bone mass in Light and T- and B-cell deficient mice (Rag- /Tnfsf14- ) supports the cooperative role of the immune system in bone homeostasis. These results implicate LIGHT as a potential target in bone disease. (c) 2017 American Society for Bone and Mineral Research. PMID- 29178460 TI - The adequate rocuronium dose required for complete block of the adductor muscles of the thigh. AB - BACKGROUND: Rocuronium can prevent the obturator jerk during transurethral resection of bladder tumors. We investigated the adequate rocuronium dose required for complete block of the thigh adductor muscles, and its correlation with individual responses of the adductor pollicis muscle to rocuronium. METHODS: Eleven patients scheduled for transurethral resection of bladder tumors under general anesthesia were investigated. After general anesthesia induction, neuromuscular monitoring of the adductor pollicis muscle and ultrasonography guided stimulation of the obturator nerve was commenced. Rocuronium, 0.15 mg/kg, was repeatedly administered intravenously. The adequate rocuronium dose required for complete block of the thigh muscles, defined as the cumulative dose of rocuronium administered until that time, and its correlation with the first twitch response of the adductor pollicis muscle on train-of-four stimulation after initial rocuronium administration was analyzed. RESULTS: The rocuronium dose found adequate for complete block of the thigh muscles was 0.30 mg/kg in seven patients and 0.45 mg/kg in the remaining four patients, which did not correlate with the first twitch response. At the time of complete block of the thigh muscles, the neuromuscular blockade level of the adductor pollicis muscle varied greatly, although the level was never more profound than a post-tetanic count of 1. CONCLUSION: Although the response of the adductor pollicis muscle to rocuronium cannot be used to determine the adequate rocuronium dose required for complete block of the thigh muscles, intense blockade, with maintenance of post tetanic count at <= 1 in the adductor pollicis muscle is essential to prevent the obturator jerk. PMID- 29178461 TI - The guardian of the genome p53 regulates exercise-induced mitochondrial plasticity beyond organelle biogenesis. AB - The Guardian of the Genome p53 has been established as a potent tumour suppressor. However, culminating from seminal findings in rodents more than a decade ago, several studies have demonstrated that p53 is required to maintain basal mitochondrial function [ie, respiration and reactive oxygen species (ROS) homeostasis]. Specifically, via its role(s) as a tumour suppressor, p53 intimately surveys cellular DNA damage, in particular mitochondrial DNA (mtDNA), to ensure that the mitochondrial network is carefully monitored and cell viability is upheld, because aberrant mtDNA damage leads to apoptosis and widespread cellular perturbations. Indeed, data from rodents and humans have demonstrated that p53 forms an integral component of the exercise-induced signal transduction network regulating skeletal muscle mitochondrial remodelling. In response to exercise-induced disruptions to cellular homeostasis that have the potential to harm mtDNA (eg, contraction-stimulated ROS emissions), appropriate p53-regulated, mitochondrial turnover responses prevail to protect the genome and ultimately facilitate a shift from aerobic glycolysis to oxidative phosphorylation, adaptations critical for endurance-based exercise that are commensurate with p53's role as a tumour suppressor. Despite these observations, several discrepancies exist between rodent and human studies pinpointing p53 subcellular trafficking from nuclear-to-mitochondrial compartments following acute exercise. Such interspecies differences in p53 activity and the plausible p53-mediated adaptations to chronic exercise training will be discussed herein.

AB - The purpose of study was to investigate the maturation of mesenchymal stem cells (MSC) laden in HA constructs with various combinations of chemically defined medium (CM) components and determine the impact of dexamethasone and serum on construct properties. Constructs were cultured in CM with the addition or withdrawal of media components or were transferred to serum containing media that partially represents an in vivo-like condition where pro-inflammatory signals are present. Constructs cultured in CM+ (CM with TGF-beta3) and DEX- (CM+ without dexamethasone) conditions produced robust matrix, while those in ITS/BSA/LA- (CM+ without ITS/BSA/LA) and Serum+ (10% FBS with TGF-beta3) produced little matrix. While construct properties in DEX- were greater than those in CM+ at 4 weeks, properties in CM+ and DEX- reversed by 8 weeks. While construct properties in DEX were greater than those in CM+ at 4 weeks, the continued absence or removal of dexamethasone resulted in marked GAG loss by 8 weeks. Conversely, the continued presence or new addition of dexamethasone at 4 weeks further improved or maintained construct properties through 8 weeks. Finally, when constructs were converted to Serum (in the continued presence of TGF-beta3 with or without dexamethasone) after pre-culture in CM+ for 4 weeks, GAG loss was attenuated with addition of dexamethasone. Interestingly, however, collagen content and type was not impacted. In conclusion, dexamethasone influences the functional maturation of MSC-laden HA constructs, and may help to maintain properties during long-term culture or with in vivo translation by repressing pro-inflammatory signals.

PMID- 29178463 TI - Psychotic (delusional) depression and suicidal attempts: a systematic review and meta-analysis. AB - OBJECTIVE: It still remains unclear whether psychotic features increase the risk of suicidal attempts in major depressive disorder. Thus, we attempted, through a systematic review coupled with a meta-analysis, to elucidate further whether unipolar psychotic depression (PMD) compared to non-PMD presents higher levels of suicidal attempts. METHOD: A systematic search was conducted in PubMed, EMBASE, PsycINFO as well as in various databases of the so-called gray literature for all studies providing data on suicidal attempts in PMD compared to non-PMD, and the results were then subjected to meta-analysis. RESULTS: Twenty studies met our inclusion criteria, including in total 1,275 PMD patients and 5,761 non-PMD patients. An elevated risk for suicide attempt for PMD compared to non-PMD patients was found: The total (lifetime) fixed-effects pooled OR was 2.11 (95% CI: 1.81-2.47), and the fixed-effects pooled OR of the five studies of the acute phase of the disorder was 1.93 (95% CI: 1.33-2.80). This elevated risk of suicidal attempt for PMD patients remained stable across all age groups of adult patients. CONCLUSION: Despite data inconsistency and clinical heterogeneity, this systematic review and meta-analysis showed that patients with PMD are at a two fold higher risk, both during lifetime and in acute phase, of committing a suicidal attempt than patients with non-PMD.

AB - OBJECTIVE: To evaluate pet owners' perceptions and understanding of surgical pain, perioperative pain management, and anesthesia. STUDY DESIGN: Prospective owner survey. SAMPLE POPULATION: Eight veterinary hospitals each provided 200 surveys for distribution to pet owners. METHODS: A survey evaluated owners' perceptions and opinions related to surgical pain, perioperative pain management, anesthesia in dogs and cats, and owner demographics (sex, age, education, employment, previous surgical experience, and pet ownership) in 8 regions of the United States (Alaska, Florida, Hawaii, Massachusetts, Oregon, Ohio, Texas, Washington, DC). Effects of demographics on survey questions were analyzed by using a Cochran-Mantel-Haenszel test. Descriptive statistics and frequency distributions were calculated when applicable. RESULTS: 948/1600 (59.25%) of distributed questionnaires were completed. Owners reported that analgesics were "always needed" more often for surgical procedures than medical conditions. Knowing what to expect during recovery (99%), being informed of procedures and risks (98%), adequate pain management (98%), and having a board-certified anesthesiologist perform anesthesia (94%) were considered "important" or "very important" by owners. The majority of owners agreed that pain affects quality of life (81%), interactions with family and pets (73%), and that declawing is a painful procedure (59%). Older respondents (>46 years), women, owners who have had previous surgery or who have pets that have had previous surgery, and those in health care professions have a better understanding of pain but also expect effective client communication. CONCLUSION: Improving our understanding of pet owners' perceptions and knowledge related to anesthesia, surgery, and pain may lead to improved client education, satisfaction, and compliance with administration of analgesics. PMID- 29178465 TI - Detection of human immunodeficiency virus, hepatitis C virus, and hepatitis B virus in postmortem blood specimens using infectious disease assays licensed for cadaveric donor screening. AB - BACKGROUND: Evaluation of assay performance on postmortem blood specimens (obtained after cessation of the heartbeat) presents unique scientific and regulatory challenges. In the United States, assay performance is evaluated in part by spiking postmortem specimens. METHODS: Fifty-four specimens obtained from decedents known to be infected with human immunodeficiency virus (HIV), hepatitis C virus (HCV), or hepatitis B virus (HBV), including some coinfections, were tested for each virus using Food and Drug Administration (FDA)-licensed donor screening tests for nucleic acid, antibody, and antigen. RESULTS: For each disease, >95% of subjects who were reported to have an infection at the time of death had a positive test result on at least one of the donor screening assays for that infection. CONCLUSION: Licensed donor screening tests were positive on postmortem specimens obtained within 24 hours of death from individuals dying with HIV, HCV, and/or HBV, and were able to detect presence of the virus. The use of multiple tests (including antibody and direct viral detection methods) is necessary to adequately evaluate donors. PMID- 29178466 TI - An approach to discussing personal and social identity terminology with patients. AB - As the United States of America becomes more socially diverse, it is more important now than ever for health care providers to become more aware of their patients' social identities. It is imperative that providers engage with their patients and see how each of them identifies personally in relation to social construction terminology. As with the terminology of human anatomy, there is a vast and diverse vocabulary concerning the anatomy of society, which is also clinically relevant to health care providers. If health care providers take the initiative to discuss how their patients identify, they can understand better how those patients experience the world, and this can significantly affect many facets of their health and health care experience. Giving respect fosters the creation of a strong relationship within which patients can share very personal and intimate information, which in turn allows health care providers the possibility of providing the best healthcare. This discussion will build upon and integrate current academic research and opinion for tangible clinical use while discussing various social and personal identities, including but not limited to race, gender, gender expression, sex, sexual orientation, religion, ethnicity, socioeconomic class, and physical and mental abilities.

AB - The development of responsive magnetic resonance imaging contrast agents opens the door to a highly sensitive and specific diagnosis of altered physiological conditions. In this field, manganese dioxide (MnO2 ) is starting to be a leading contributor due to its susceptibility to conditions relevant to human diseased states, such as cancer. So far, the preclinical application of MnO2 has mainly been in the form of nanosheets, with enhancements of magnetic resonance imaging signals up to 50-fold upon activation. Herein, we thoroughly investigate, through a simple reaction, a series of Mnx Oy samples and correlate their phase composition and structure/morphology to the performance as classic/responsive MRI contrast agents in response to redox changes. Signal enhancements as high as 140 fold were obtained from MnO2 nano-urchins, and their capability as responsive magnetic resonance imaging contrast agents was demonstrated in vitro. PMID- 29178468 TI - DFT calculations of the defect structures, electronic structures, and EPR parameters for three Rh2+ centers in AgCl. AB - The local structures for various Rh2+ centers in AgCl are theoretically studied using density functional theory (DFT) with periodic CP2K program. Through geometry optimizing, the stable ground states with minimal energies and electronic structures are obtained for the tetragonally elongated (TE ), orthorhombically elongated (OE ), and tetragonally compressed (TC ) centers, and the corresponding g and hyperfine coupling tensors are calculated in ORCA level. The calculations reveal obvious Jahn-Teller elongation distortions of about 0.109 and 0.110 A along [001] axis for TE and OE centers without and with 1 next nearest neighbor (nnn) cation vacancy VAg in [100] axis, respectively. Whereas TC center with 1 nnn VAg along [001] axis exhibits moderate axial compression of about 0.066 A due to the Jahn-Teller effect. For OE and TC centers with 1 nnn VAg , the ligand intervening in the central Rh2+ and the VAg is found to displace away from the VAg by about 0.028 and 0.024 A, respectively. The present results are discussed and compared with those of the previous calculations based on the perturbation formulas by using the improved ligand field theory. PMID- 29178469 TI - Multiracial in Middle School: The Influence of Classmates and Friends on Changes in Racial Self-Identification. AB - In the present research, the influence of racial diversity among classmates and friends on changes in racial self-identification among multiracial youth was examined (n = 5,209; Mage = 10.56 years at the beginning of sixth grade). A novel individual-level measure of diversity among classmates based on participants' course schedules was utilized. The findings revealed that although there was some fluidity in multiracial identification at the beginning of middle school, changes in multiracial identification were more evident later in middle school. In addition, although diversity among classmates and friends both increased the likelihood of multiracial identification in the beginning of middle school, only diversity among friends mattered later in middle school, when fluidity in multiracial identification was at its peak. PMID- 29178470 TI - Lymphocyte-independent pathways underlie the pathogenesis of murine cytomegalovirus-associated secondary haemophagocytic lymphohistiocytosis. AB - Haemophagocytic lymphohistiocytosis (HLH) constitutes a spectrum of immunological disorders characterized by uncontrolled immune activation and key symptoms such as fever, splenomegaly, pancytopenia, haemophagocytosis, hyperferritinaemia and hepatitis. In genetic or primary HLH, hyperactivated CD8+ T cells are the main drivers of pathology. However, in acquired secondary HLH, the role of lymphocytes remains vague. In the present study the involvement of lymphocytes in the pathogenesis of a cytomegalovirus-induced model of secondary HLH was explored. We have previously reported CD8+ T cells to be redundant in this model, and therefore focused on CD4+ helper and regulatory T cells. CD4+ T cells were activated markedly and skewed towards a proinflammatory T helper type 1 transcription profile in mice displaying a severe and complete HLH phenotype. Counter to expectations, regulatory T cells were not reduced in numbers and were, in fact, more activated. Therapeutic strategies targeting CD25high hyperactivated T cells were ineffective to alleviate disease, indicating that T cell hyperactivation is not a pathogenic factor in cytomegalovirus-induced murine HLH. Moreover, even though T cells were essential in controlling viral proliferation, CD4+ T cells, in addition to CD8+ T cells, were dispensable in the development of the HLH-like syndrome. In fact, no T or B cells were required for induction and propagation of HLH disease, as evidenced by the occurrence of cytomegalovirus associated HLH in severe combined immunodeficient (SCID) mice. These data suggest that lymphocyte-independent mechanisms can underlie virus-associated secondary HLH, accentuating a clear distinction with primary HLH.

AB - INTRODUCTION: Methacholine Challenge Test (MCT) is used to confirm, assess the severity and/or rule out asthma. Two MCT methods are described as equivalent by the American Thoracic Society (ATS), the tidal breathing and the dosimeter methods. However, the majority of adult studies suggest that individuals with asthma do not react at the same PC20 between the two methods. Additionally, the nebulizers used are no longer available and studies suggest current nebulizers are not equivalent to these. Our study investigates the difference in positive MCT tests between three methods in a pediatric population. METHODS: A retrospective, chart review of all MCT performed with spirometry at the Montreal Children's Hospital from January 2006 to March 2016. A comparison of the percentage positive MCT tests with three methods, tidal breathing, APS dosimeter and dose adjusted DA-dosimeter, was performed at different cutoff points up to 8 mg/mL. RESULTS: A total of 747 subjects performed the tidal breathing method, 920 subjects the APS dosimeter method, and 200 subjects the DA-dosimeter method. At a PC20 cutoff <=4 mg/mL, the percentage positive MCT was significantly higher using the tidal breathing method (76.3%) compared to the APS dosimeter (45.1%) and DA dosimeter (65%) methods (P < 0.0001). CONCLUSION: The choice of nebulizer and technique significantly impacts the rate of positivity when using MCT to diagnose and assess asthma. Lack of direct comparison of techniques within the same individuals and clinical assessment should be addressed in future studies to standardize MCT methodology in children.

AB - In situ cross-linked hyaluronan (HA) hydrogels with different capacities for biomineralization were prepared and their enzymatic degradation was monitored. Covalent incorporation of bisphosphonates (BPs) into HA hydrogel results in the increased stiffness of the hydrogel in comparison with the unmodified HA hydrogel of the same cross-linking density. The rate of enzymatic degradation of HABP hydrogel was significantly lower than the rate of degradation of control HA hydrogel in vitro. This effect is observed only in the presence of calcium ions that strongly bind to the matrix-anchored BP groups and promote further mineralization of the matrix. The degradation of the hydrogels was followed by noninvasive fluorescence measurements enabled after mild and chemoselective labeling of cross-linkable HA derivatives with a fluorescent tag. PMID- 29178473 TI - Thermochemistry of Substituted Benzamides and Substituted Benzoic Acids: Like Tree, Like Fruit? AB - Structure-property analyses of thermodynamic properties in chemical families of R substituted benzamides, R-substituted benzoic acids, as well as R-substituted benzenes have been performed. The general linear interrelations for the vaporization enthalpies and the gas-phase enthalpies of formation between the chemical families under study have been established. These linear correlations provide a simple method for prediction of thermodynamic properties for benzenes with various combination of R-group substituents on the benzene ring. In addition, the robust structure-property correlations revealed in this study can serve for the establishment of the internal consistency of experimental results available for each chemical series. PMID- 29178474 TI - In vivo Confocal Laser Microscopy for monitoring of actinic keratosis treatment: a comparison with histopathologic assessment after treatment with topical 5% 5 fluorouracil. AB - BACKGROUND: Histological examination is the gold standard for actinic keratosis diagnosis; however, it is not always a feasible approach. Reflectance confocal microscopy (RCM) is a non-invasive technique that may be an alternative for monitoring actinic keratoses treatment response. Topical 5-fluorouracil is indicated for actinic keratosis multiple lesions and for field cancerization treatment. OBJECTIVES: To assess the RCM accuracy, sensibility and specificity for actinic keratosis, considering as a gold standard the histopathological examination; as well as to evaluate the efficacy of 5% 5-fluorouracil treatment. METHODS: This is a prospective study in actinic keratosis patients between August 2014 and November 2015. RCM analyses were performed in one randomly selected actinic keratosis lesion of the upper limbs by two independent observers before and after 5% 5-fluorouracil treatment. At the end of treatment and with clinical bleaching of treated lesions, histological examination was performed by two pathologists. RESULTS: A total of 50 lesions were enroled, and 40 lesions presented complete clinical bleaching after treatment and were included in the final analysis. Accuracy, sensibility and specificity means among observers were 83.8%, 84.6% and 83.3%, respectively. After 5-fluorouracil treatment, actinic keratosis was diagnosed in 45.0% (observer 1) and 32.5% (observer 2) of subjects according to RCM and in 32.5% of subjects according to histological examination. Considering RCM observers diagnosis, the concordance was substantial (k 0.637, P < 0.001). 5-fluorouracil led to a reduction in 55.0%-67.5% of actinic keratoses according to RCM analysis. CONCLUSION: This study allows to validate RCM as a non invasive method capable of monitoring actinic keratosis therapeutic response to 5 fluorouracil, presenting efficacy comparable to histological examination. Additionally, the results suggest that 5-fluorouracil may be a satisfactory option for therapeutic control of this condition. PMID- 29178475 TI - Transcriptional analysis of the IL-33 receptor suppression of tumourigenicity 2 and its effects on canine Type 2 T helper cells: a preliminary study. AB - BACKGROUND: Interleukin (IL)-33 has been implicated in the pathogenesis of canine atopic dermatitis, a Type 2 T helper cell (Th2)-associated disease. In humans, IL 33 mediates its biological effects through the receptor suppression of tumourigenicity 2 (ST2), which is preferentially expressed on Th2 cells. The effects of IL-33 on canine Th2 cells are unclear. HYPOTHESIS/OBJECTIVES: ST2 may be preferentially expressed on canine Th2 cells; IL-33 may induce the transcription of Th2 cytokines from these cells. ANIMALS: Three healthy dogs were used. METHODS: The transcription level of st2 was quantified in helper T cells, cytotoxic T cells and Th2 cells isolated from healthy dogs. The transcription levels of Th2 cytokines including il-4, il-5, il-13 and il-31 were quantified in Th2 cells stimulated with recombinant canine (rc) IL-33 and/or recombinant human (rh) IL-2. RESULTS: Transcription of st2 was the strongest in Th2 cells. Th2 cells also transcribed the genes for il-5 and il-13 after being stimulated with rcIL-33 and rhIL-2. CONCLUSIONS AND CLINICAL IMPORTANCE: These results indicate that canine Th2 cells activated by IL-33 enhance Th2-mediated inflammation through the production of IL-5 and IL-13. PMID- 29178476 TI - A network of jasmonate-responsive bHLH factors modulate monoterpenoid indole alkaloid biosynthesis in Catharanthus roseus. AB - The pharmaceutically valuable monoterpene indole alkaloids (MIAs) in Catharanthus roseus are derived from the indole and iridoid pathways that respond to jasmonate (JA) signaling. Two classes of JA-responsive bHLH transcription factor (TF), CrMYC2 and BIS1/BIS2, are known to regulate the indole and iridoid pathways, respectively. However, upregulation of either one of the TF genes does not lead to increased MIA accumulation. Moreover, little is known about the interconnection between the CrMYC2 and BIS transcriptional cascades and the hierarchical position of BIS1/BIS2 in JA signaling. Here, we report that a newly identified bHLH factor, Repressor of MYC2 Targets 1 (RMT1), is activated by CrMYC2 and BIS1, and acts as a repressor of the CrMYC2 targets. In addition, we isolated and functionally characterized the core C. roseus JA signaling components, including CORONATINE INSENSITIVE 1 (COI1) and JASMONATE ZIM domain (JAZ) proteins. CrMYC2 and BIS1 are repressed by the JAZ proteins in the absence of JA, but de-repressed by the SCFCOI1 complex on perception of JA. Our findings suggest that the repressors, JAZs and RMT1, mediate crosstalk between the CrMYC2 and BIS regulatory cascades to balance the metabolic flux in MIA biosynthesis. PMID- 29178477 TI - The anatomy of forearm free flap phalloplasty for transgender surgery. AB - Transgender surgeries are becoming more frequent and visual interpretation of anatomy is essential for both surgeons and patients. Since the forearm free flap phalloplasty was introduced in 1984, it has been known to provide reliable cosmetic and functional results for transitioning men compared with phalloplasty by different flaps. Surgical text descriptions were enhanced by the creation of new anatomic illustrations. The forearm free flap consists of the anterior forearm skin, subcutaneous tissue, fascia containing the radial artery as the perforator and its venae comitantes, cephalic and basilic veins, and lateral and medial antebrachial cutaneous nerves are demonstrated in relation to the surgically derived flap. Song's forearm free flap phalloplasty requires two surgical stages with a three-month interval between the stages: prelamination of a neourethra and construction of a neophallus. The neophallus created by forearm flap phalloplasty is reported to achieve acceptable aesthetical and psychological satisfaction, appropriate size and shape, and satisfying sexual intercourse. Despite increasing experiences in gender confirming surgery with modifications made by many authors, urethral complications including fistula and/or stricture formation are the leading causes of reoperation. The poor esthetic outcome of the forearm donor site and a decrease in rigidity of the neophallus are the main limitations. Illustrations of anatomy help inform surgical choice and understanding of risks and benefits by patients. The anatomy of the free forearm flap phalloplasty supports creation of a neophallus for transsexual anatomy revision. Clin. Anat. 31:145-151, 2018. (c) 2017 Wiley Periodicals, Inc. PMID- 29178478 TI - From yeast to humans - roles of the Kennedy pathway for phosphatidylcholine synthesis. AB - The major phospholipid present in most eukaryotic membranes is phosphatidylcholine (PC), comprising ~ 50% of phospholipid content. PC metabolic pathways are highly conserved from yeast to humans. The main pathway for the synthesis of PC is the Kennedy (CDP-choline) pathway. In this pathway, choline is converted to phosphocholine by choline kinase, phosphocholine is metabolized to CDP-choline by the rate-determining enzyme for this pathway, CTP:phosphocholine cytidylyltransferase, and cholinephosphotransferase condenses CDP-choline with diacylglycerol to produce PC. This Review discusses how PC synthesis via the Kennedy pathway is regulated, its role in cellular and biological processes, as well as diseases known to be associated with defects in PC synthesis. Finally, we present the first model for the making of a membrane via PC synthesis. PMID- 29178479 TI - Face allotransplantation for various types of facial disfigurements: A series of five cases. AB - BACKGROUND: The aim of this report is to present our long-term experiences with a series of 5 face-transplanted patients in terms of surgical aspects and postoperative outcomes, and to describe possible salvage strategies in case of difficulties. METHODS: Five patients, 4 receiving full-face transplantation and 1 undergoing partial transplantation at our institution were included. The patients were aged between 19 and 54 years. Two had extensive burn scars to the face, and 3 had suffered gunshot injuries. The post-transplant induction immunosuppressive regimen included ATG combined with tacrolimus, mycophenolate mofetil, and prednisone, while maintenance was provided by the last 3. We focused on patient summaries including their etiologies, preoperative preparations, surgical techniques, immunosuppressive regimen, postoperative courses, revisional surgeries, together with challenges including acute rejection episodes, and immunosuppressive drug complications. RESULTS: No re-surgery due to vascular compromise was required in any case. One of the 5 patients was eventually lost due to complicated infectious and metabolic events at the end of post transplantation month 11. The other 4 patients were still alive, with a mean follow-up time of 53 months and had satisfactory functional transplants and cosmetic appearance. CONCLUSIONS: Face transplantation still involves challenges and many issues including compliance and psychological maturity of patients, the risk of opportunistic infections and malignancies still need to be resolved for it to be accepted as a safe procedure. Surgical rescue procedures considering ideal timing should be kept in mind strictly as one of the most important issues in case of unexpected events.

AB - The degradation of streams caused by urbanization tends to follow predictable patterns; however, there is a growing appreciation for heterogeneity in stream response to urbanization due to the local geoclimatic context. Furthermore, there is building evidence that streams in mildly sloped, permeable landscapes respond uncharacteristically to urban stress calling for a more nuanced approach to restoration. We evaluated the relative influence of local-scale riparian characteristics and catchment-scale imperviousness on the macroinvertebrate assemblages of streams in the flat, permeable urban landscape of Perth, Western Australia. Using a hierarchical multi-taxa model, we predicted the outcomes of stylized stream restoration strategies to increase the riparian integrity at the local scale or decrease the influences of imperviousness at the catchment scale. In the urban streams of Perth, we show that local-scale riparian restoration can influence the structure of macroinvertebrate assemblages to a greater degree than managing the influences of catchment-scale imperviousness. We also observed an interaction between the effect of riparian integrity and imperviousness such that the effect of increased riparian integrity was enhanced at lower levels of catchment imperviousness. This study represents one of few conducted in flat, permeable landscapes and the first aimed at informing urban stream restoration in Perth, adding to the growing appreciation for heterogeneity of the Urban Stream Syndrome and its importance for urban stream restoration. PMID- 29178480 TI - Hydrogel Encapsulation Facilitates Rapid-Cooling Cryopreservation of Stem Cell Laden Core-Shell Microcapsules as Cell-Biomaterial Constructs. AB - Core-shell structured stem cell microencapsulation in hydrogel has wide applications in tissue engineering, regenerative medicine, and cell-based therapies because it offers an ideal immunoisolative microenvironment for cell delivery and 3D culture. Long-term storage of such microcapsules as cell biomaterial constructs by cryopreservation is an enabling technology for their wide distribution and ready availability for clinical transplantation. However, most of the existing studies focus on cryopreservation of single cells or cells in microcapsules without a core-shell structure (i.e., hydrogel beads). The goal of this study is to achieve cryopreservation of stem cells encapsulated in core shell microcapsules as cell-biomaterial constructs or biocomposites. To this end, a capillary microfluidics-based core-shell alginate hydrogel encapsulation technology is developed to produce porcine adipose-derived stem cell-laden microcapsules for vitreous cryopreservation with very low concentration (2 mol L 1 ) of cell membrane penetrating cryoprotective agents (CPAs) by suppressing ice formation. This may provide a low-CPA and cost-effective approach for vitreous cryopreservation of "ready-to-use" stem cell-biomaterial constructs, facilitating their off-the-shelf availability and widespread applications. PMID- 29178483 TI - Electrochemotherapy of unresectable cutaneous tumours with reduced dosages of intravenous bleomycin: analysis of 57 patients from the International Network for Sharing Practices of Electrochemotherapy registry. AB - BACKGROUND: Electrochemotherapy (ECT) is currently used to treat unresectable superficial tumours of different histotypes through the combination of cytotoxic chemotherapy and local application of electric pulses. In 2006, a collaborative project defined the ESOPE (European Standard Operating Procedures of Electrochemotherapy) guidelines to standardize the procedure. The International Network for Sharing Practices of Electrochemotherapy (InspECT) aims to refine the ESOPE and improve clinical practice. Limiting patient exposure to systemic chemotherapy would be advisable to ameliorate ECT safety profile. OBJECTIVE: The aim of this study was to evaluate the efficacy and toxicity of ECT with reduced chemotherapy dosages. METHODS: In a retrospective analysis of a prospectively maintained database (InspECT registry), we evaluated the outcome of patients who received ECT with reduced dosages of bleomycin (7500, 10 000 or 13 500 IU/m2 , instead of the standard dose of 15 000 IU/m2 ). Tumour response in melanoma patients was compared with melanoma patients of the InspECT registry who received the standard dose of bleomycin. RESULTS: We identified 57 patients with 147 tumours (melanoma, 38.6%; squamous cell carcinoma, 22.8%; basal cell carcinoma, 17.5%; breast cancer 7%; Kaposi sarcoma 7%; other histotypes, 7.1%). Per-tumour complete response (CR) rate at 60 days was 70.1% (partial, 16.3%); per-patient CR was 57.9% (partial, 21.1%). Local pain was the most frequently reported side effect (n = 22 patients [39%]), mostly mild; two patients experienced flu-like symptoms, one patient nausea. We observed the same CR rate (55%) in patients with melanoma treated by reduced or conventional bleomycin dosages (P = 1.00). CONCLUSIONS: Electrochemotherapy performed with reduced bleomycin dosages could be as effective as with currently recommended dose. Patients with impaired renal function or candidate to multiple ECT cycles could benefit from a reduced dose protocol. Our findings need prospective confirmation before being adopted in clinical practice. PMID- 29178484 TI - A Single Mutation is Sufficient to Modify the Metal Selectivity and Specificity of a Eukaryotic Manganese Superoxide Dismutase to Encompass Iron. AB - We have generated a site-directed mutant of the manganese superoxide dismutase SOD-3 of C.elegans (MnSOD-3) which modifies the metal specificity of the enzyme. While wild-type MnSOD-3 functions with manganese in the active site (3600 U mg-1 of protein) it has little or no activity when iron is incorporated. However, when histidine replaces glutamine 142 in the active site, the enzyme retains 50 % of its activity and becomes cambialistic for its metal cofactor exhibiting very similar specific activity with either manganese or iron. PMID- 29178485 TI - Shelf-Life of Boiled Salted Duck Meat Stored Under Normal and Modified Atmosphere. AB - : The objective of this study was to investigate the physicochemical properties and changes in the microbial counts of boiled salted duck (BSD) meat packed under various conditions. BSD meat was stored under normal atmosphere (C) and two modified atmosphere packaging (MAP) conditions: M1 (N2 , 100%) and M2 (CO2 /N2 , 30%/70%) at 4 degrees C. Microbiological quality, pH, redness, lipid oxidation, headspace gas composition, and water activity of BSD meat were measured. The results showed that the time to reach the maximum acceptable total viable counts (TVC, 4.9 log CFU/g) was 12, 18, and 21 d in C, M1, and M2 samples, respectively. Significant difference in the redness values was observed in all treatments during storage. The redness value of C group was significantly lower than that in M1 and M2 groups at the end of storage. The thiobarbituric acid-reactive substances (TBARS) values under MAP were 0.24 to 0.26 mg MDA/kg meat at the end of storage, lower (P < 0.05) than that in C group (0.78 mg MDA/kg meat). The water activity in M2 group was the lowest among all 3 groups. The CO2 concentration in M2 decreased significantly during storage. Our study demonstrates that packaging with 30% CO2 and 70% N2 (M2) could extend the shelf life of BSD meat to 21 d during storage at 4 degrees C, suggesting that MAP can be a practical approach to extend the shelf-life and maintain the quality of BSD products. PRACTICAL APPLICATION: This study evaluated the application of MAP for a cooked duck product. Our results showed that MAP can be utilized to extend the shelf-life. This technology may be used for preservation of other cooked meat products. PMID- 29178486 TI - Developing and characterizing MR/CT-visible materials used in QA phantoms for MRgRT systems. AB - PURPOSE: Synthetic tissue equivalent (STE) materials currently used to simulate tumor and surrounding tissues for IROC-Houston's anthropomorphic head and thorax QA phantoms cannot be visualized using magnetic resonance (MR) imaging. The purpose of this study was to characterize dual MR/CT-visible STE materials that can be used in an end-to-end QA phantom for MR-guided radiotherapy (MRgRT) modalities. METHODS: Over 80 materials' MR, CT, and dosimetric STE properties were investigated for use in MRgRT QA phantoms. The materials tested included homogeneous and heterogeneous materials to simulate soft tissue/tumor and lung tissues. Materials were scanned on a Siemens' Magnetom Espree 1.5 T using four sequences, which showed the materials visual contrast between T1- and T2-weighted images. Each material's Hounsfield number and electron density data was collected using a GE's CT Lightspeed Simulator. Dosimetric properties were examined by constructing a 10 * 10 * 20 cm3 phantom of the selected STE materials that was divided into three sections: anterior, middle, and posterior. Anterior and posterior pieces were composed of polystyrene, whereas the middle section was substituted with the selected STE materials. EBT3 film was inserted into the phantom's midline and was irradiated using an Elekta's Versa 6 MV beam with a prescription of 6 Gy at 1.5 cm and varying field size of: 10 * 10 cm2 , 6 * 6 cm2 , and 3 * 3 cm2 . Measured film PDD curves were compared to planning system calculations and conventional STE materials' percent depth dose (PDD) curves. RESULTS: The majority of the tested materials showed comparable CT attenuation properties to their respective organ site; however, most of the tested materials were not visible on either T1- or T2-weighted MR images. Silicone, hydrocarbon, synthetic gelatin, and liquid PVC plastic-based materials showed good MR image contrast. In-house lung equivalent materials made with either silicone- or hydrocarbon-based materials had HUs ranging from: -978 to -117 and -667 to -593, respectively. Synthetic gelatin and PVC plastic-based materials resembled soft tissue/tumor equivalent materials and had HUs of: -175 to -170 and -29 to 32, respectively. PDD curves of the selected MR/CT-visible materials were comparable to IROC-Houston's conventional phantom STE materials. The smallest field size showed the largest disagreements, where the average discrepancies between calculated and measured PDD curves were 1.8% and 5.9% for homogeneous and heterogeneous testing materials, respectively. CONCLUSIONS: Gelatin, liquid plastic, and hydrocarbon-based materials were determined as alternative STE substitutes for MRgRT QA phantoms. PMID- 29178487 TI - Therapeutic Benefit of Smoked Cannabis in Randomized Placebo-Controlled Studies. AB - The medicinal use of marijuana has been legalized in 28 states, with a wide range of specificity for approved medical conditions. Even with the emergence of non combustion-based delivery systems, 90% of marijuana users in 2014 used smoked marijuana. This review summarizes the data available on the use of smoked marijuana for medical purposes. A literature search was performed to retrieve randomized controlled trials exploring the efficacy of smoked cannabis for treatment of a medical condition. Studies with the primary end point listed as the effect of smoked cannabis on a disease-specific characteristic were included. Open-label studies and studies using other administration methods were excluded. Seven studies met these criteria and were included in this review. Cannabis did not outperform placebo on experimentally evoked pain or the timed walk test. Clear evidence indicates that smoked cannabis reduces intraocular pressure, but the effect is too brief (less than 4 hrs) to be of therapeutic benefit for this chronic disorder. Consistent evidence also showed that smoked marijuana, even at lower concentrations of tetrahydrocannabinol, increased total daily calorie intake and number of eating occasions. Neither of the studies with quality of life as secondary outcome measures revealed statistically significantly improved outcomes with cannabis use. PMID- 29178488 TI - The anatomy of abdominal flap phalloplasty for transgender surgery. AB - Abdominal flap phalloplasty is surgical construction of a neophallus using a pedicled abdominal flap for patients transitioning female to male, for males whose penis is congenitally absent, or lost from trauma. It is an option for trans men whose goals do not require urethroplasty or vaginectomy but would like a phallus suitable for male gender appearance. A prosthesis can be placed for penetrative sexual capability. Surgical text descriptions were enhanced by creation of new anatomic illustrations. Anatomy of donor site and surgical technique leading to creation of the neophallus are demonstrated in detail with new relevant illustrations. Significant structures of the donor site of the abdominal flap include the superficial external pudendal artery and ilioinguinal nerve that provide the blood supply and sensory innervation to the base of the flap, respectively. As a pedicled phalloplasty procedure, microsurgical anastomosis is not needed. Patients can expect to have tactile sensation but not innate rigidity. The dorsal nerve of clitoris (and sometimes the clitoris itself) is preserved to provide erogenous sensation. Abdominal flap phalloplasty makes it possible to maintain the natural blood supply and innervation to the neophallus. The neophallus created by abdominal flap phalloplasty has the advantage of homogeneous skin color and texture from contiguous skin. Grafting leaves a less stigmatizing horizontal scar running from one side of the pelvis to the other along the lower abdomen. The anatomy of the abdominal flap phalloplasty supports creation of a neophallus for transsexual anatomy revision. Clin. Anat. 31:181 186, 2018. (c) 2017 Wiley Periodicals, Inc. PMID- 29178489 TI - Daily inspiratory muscle training lowers blood pressure and vascular resistance in healthy men and women. AB - NEW FINDINGS: What is the central question of this study? What impact does inspiratory muscle training have on systemic vascular resistance, cardiac output and baroreflex sensitivity in adult men and women? What is the main finding and its importance? Inspiratory muscle training exerts favorable effects on blood pressure, vascular resistance and perception of stress. This exercise format is well-tolerated and equally effective whether implemented in men or women. ABSTRACT: Previous work has shown that inspiratory muscle training (IMT) lowers blood pressure after a mere 6 weeks, identifying IMT as a potential therapeutic intervention to prevent or treat hypertension. Here, we explore the effects of IMT on respiratory muscle strength and select cardiovascular parameters in recreationally active men and women. Subjects were randomly assigned to IMT (n = 12, 75% maximal inspiratory pressure) or sham training (n = 13, 15% maximal inspiratory pressure) groups and underwent a 6-week intervention comprising 30 breaths day-1 , 5 days week-1 . Pre- and post-training measures included maximal inspiratory pressure and resting measures of blood pressure, cardiac output, heart rate, spontaneous cardiac baroreflex sensitivity and systemic vascular resistance. We evaluated psychological and sleep status via administration of the Cohen-Hoberman inventory of physical symptoms and the Epworth sleepiness scale. Male and female subjects in the IMT group showed declines in systolic/diastolic blood pressures (-4.3/-3.9 mmHg, P < 0.025) and systemic vascular resistance ( 3.5 mmHg min l-1 , P = 0.008) at week 6. There was no effect of IMT on cardiac output (P = 0.722), heart rate (P = 0.795) or spontaneous cardiac baroreflex sensitivity (P = 0.776). The IMT subjects also reported fewer stress-related symptoms (pre- versus post-training, 12.5 +/- 8.5 versus 7.2 +/- 9.7, P = 0.025). Based on these results, we suggest that a short course of IMT confers significant respiratory and cardiovascular improvements and parallel (modest) psychological benefits in healthy men and women. PMID- 29178490 TI - A Bifunctional Perovskite Promoter for Polysulfide Regulation toward Stable Lithium-Sulfur Batteries. AB - Lithium-sulfur (Li?S) batteries are strongly considered as the next-generation rechargeable cells. However, both the shuttle of lithium polysulfides (LiPSs) and sluggish kinetics in random deposition of lithium sulfides (Li2 S) significantly degrade the capacity, rate performance, and cycling life of Li?S cells. Herein, bifunctional Ba0.5 Sr0.5 Co0.8 Fe0.2 O3-delta perovskite nanoparticles (PrNPs) are proposed as a promoter to immobilize LiPSs and guide the deposition of Li2 S in a Li?S cell. The oxygen vacancy in PrNPs increases the metal reactivity to anchor LiPSs, and co-existence of lithiophilic (O) and sulfiphilic (Sr) sites in PrNP favor the dual-bonding (Li?O and Sr?S bonds) to anchor LiPSs. The high catalytic nature of PrNP facilitates the kinetics of LiPS redox reaction. The PrNP with intrinsic LiPS affinity serves as nucleation sites for Li2 S deposition and guides its uniform propagation. Therefore, the bifunctional LiPS promoter in Li?S cell yields high rate performance and ultralow capacity decay rate of 0.062% (a quarter of pristine Li?S cells). The proposed strategy to immobilize LiPSs, promotes the conversion of LiPS, and regulates deposition of Li2 S by an emerging perovskite promoter and is also expected to be applied in other energy conversion and storage devices based on multi-electron redox reactions. PMID- 29178491 TI - Pharmacokinetic and Pharmacodynamic Modeling of Serum Etrolizumab and Circulating beta7 Receptor Occupancy in Patients With Ulcerative Colitis. AB - Etrolizumab, a humanized monoclonal antibody, specifically binds to the beta7 subunit of the heterodimeric integrins alpha4beta7 and alphaEbeta7. Pharmacokinetic (PK) and pharmacodynamic (PD) data were collected from an etrolizumab phase 1 trial in patients with moderate to severe ulcerative colitis (UC). We developed a mechanism-based model to simultaneously describe the kinetics of serum etrolizumab concentration and free beta7 receptors on circulating intestinal-homing CD4+ T lymphocytes. Included in the analysis were 38 phase 1 UC patients who received single or 3 monthly doses of etrolizumab intravenously or subcutaneously across a dose range of 0.3 to 10 mg/kg. A quasi steady-state target-mediated drug disposition model was developed to describe the dynamic interaction between serum etrolizumab concentration and free beta7 receptors on intestinal-homing CD4+ T lymphocytes in UC patients. The time profiles of serum etrolizumab and absolute counts of beta7+ lymphocytes (expressed as percentage of baseline level) were well described by the quasi steady-state target-mediated drug disposition model. The model was able to characterize the maximum drug occupancy of beta7 receptors on intestinal-homing CD4+ T lymphocytes and the concentration-dependent duration of occupancy. The 90% effective concentration for etrolizumab to saturate the beta7 receptors on intestinal homing CD4+ T cells was 1.3 MUg/mL. PK and PD profiles predicted by the model were consistent with observations from a subsequent phase 2 study. In conclusion, an integrated PK/PD model developed in this analysis reasonably described serum etrolizumab PK profiles and the relationship between PK and PD (free beta7 receptors on circulating intestinal-homing CD4+ T lymphocytes) in UC patients. PMID- 29178492 TI - Contactless Visualization of Latent Fingerprints on Nonporous Curved Surfaces of Circular Cross Section-A Statistical Evaluation on the Materials as Plane Mirror. AB - A new contactless technique for latent fingerprint visualization on nonporous curved surfaces of circular cross section was introduced by Low et al. (1). The technique utilizes a plane mirror to convey the light rays toward the inspected surfaces for latent fingerprint visualization. This research activity came up as an extension of the previous study which utilized an aluminum plate as the plane mirror to illuminate the inspected surfaces. Dulling spray was used to increase the diffuse component of the reflective aluminum plate. However, the amount of dulling spray will affect the uniformity of the illumination on the inspected curved surfaces. In this study, a study on the new materials for the plane mirror was carried out. Coated aluminum, opal, and ground glass diffusers were selected as the new materials. The performance of the new materials was compared to the aluminum based on the quality of the captured images on various nonporous cylindrical surfaces. A statistical approach known as randomized complete block design was used to design the experiment. The quality of the captured images was obtained using Spectral Image Validation and Verification. Two-way analysis of variance and Fisher's least significant difference test were used to analyze the quality of the images. From the results of the statistical analysis, coated aluminum has the best performance compared to aluminum, opal, and ground glass diffusers. PMID- 29178493 TI - Can MM/GBSA calculations be sped up by system truncation? AB - We have studied whether calculations of the binding free energy of small ligands to a protein by the MM/GBSA approach (molecular mechanics combined with generalized Born and surface area solvation) can be sped up by including only a restricted number of atoms close to the ligand. If the protein is truncated before the molecular dynamics (MD) simulations, quite large changes are observed for the calculated binding energies, for example, 4 kJ/mol average difference for a radius of 19 A for the binding of nine phenol derivatives to ferritin. The results are improved if no atoms are fixed in the simulations, with average and maximum errors of 2 and 3 kJ/mol at 19 A and 3 and 6 kJ/mol at 7 A. Similar results are obtained for two additional proteins, p38alpha MAP kinase and factor Xa. On the other hand, if energies are calculated on snapshots that are truncated after the MD simulation, all residues more than 8.5 A from the ligand can be omitted without changing the energies by more than 1 kJ/mol on average (maximum error 1.4 kJ/mol). At the molecular mechanics level, the gain in computer time for such an approach is small. However, it shows what size of system should be used if the energies instead are calculated with a more demanding method, for example, quantum-mechanics. (c) 2017 Wiley Periodicals, Inc. PMID- 29178494 TI - Microvascular characteristics of the acoustic fats: Novel data suggesting taxonomic differences between deep and shallow-diving odontocetes. AB - Odontocetes have specialized mandibular fats, the extramandibular (EMFB) and intramandibular fat bodies (IMFB), which function as acoustic organs, receiving and channeling sound to the ear during hearing and echolocation. Recent strandings of beaked whales suggest that these fat bodies are susceptible to nitrogen (N2 ) gas embolism and empirical evidence has shown that the N2 solubility of these fat bodies is higher than that of blubber. Since N2 gas will diffuse from blood into tissue at any blood/tissue interface and potentially form gas bubbles upon decompression, it is imperative to understand the extent of microvascularity in these specialized acoustic fats so that risk of embolism formation when diving can be estimated. Microvascular density was determined in the EMFB, IMFB, and blubber from 11 species representing three odontocete families. In all cases, the acoustic tissues had less (typically 1/3 to 1/2) microvasculature than did blubber, suggesting that capillary density in the acoustic tissues may be more constrained than in the blubber. However, even within these constraints there were clear phylogenetic differences. Ziphiid (Mesoplodon and Ziphius, 0.9 +/- 0.4% and 0.7 +/- 0.3% for EMFB and IMFB, respectively) and Kogiid families (1.2 +/- 0.2% and 1.0 +/- 0.01% for EMFB and IMFB, respectively) had significantly lower mean microvascular densities in the acoustic fats compared to the Delphinid species (Tursiops, Grampus, Stenella, and Globicephala, 1.3 +/- 0.3% and 1.3 +/- 0.3% for EMFB and IMFB, respectively). Overall, deep-diving beaked whales had less microvascularity in both mandibular fats and blubber compared to the shallow-diving Delphinids, which might suggest that there are differences in the N2 dynamics associated with diving regime, phylogeny, and tissue type. These novel data should be incorporated into diving physiology models to further understand potential functional disruption of the acoustic tissues due to changes in normal diving behavior.

AB - BACKGROUND: While device-based acne treatments are widely applied for patients not tolerating conventional medications, related controlled studies have been still limited. Recently, non-ablative 1450-nm diode laser (DL) and fractional microneedling radiofrequency (FMR) have been effectively used for acne, in addition to well-recognized dermal remodelling effects. OBJECTIVE: To compare the clinical course of acne treatment between DL and FMR. METHODS: Twenty-five Korean patients with mild-to-moderate facial acne completed treatments with DL and FMR through a 20-week, randomized split-face study. One randomly assigned half side of each patient's face received DL and the other side by FMR. Treatments were scheduled to receive three consecutive sessions at 4-week intervals. Objective assessments including revised Leeds grades, lesion counts, sebum output measurements, and patients' subjective satisfaction were investigated. RESULTS: Both DL and FMR demonstrated steady improvement of acne and seborrhoea during treatment sessions. While results between two devices were similar during treatment sessions, FMR was superior to DL in the 12-week follow-up. Patients' subjective assessments for seborrhoea improvement were similar between two devices, while those for acne, skin texture, and acne scars were more satisfactory for FMR. For safety profile, no significant difference was observed between two regimens, while mild postinflammatory hyperpigmentation was observed only in DL side. CONCLUSION: Both DL and FMR demonstrated efficacies for acne and seborrhoea, with reasonable safety profile. FMR was more effective than DL for the long-term maintenance, and subjective assessments for texture and scar improvements. Therefore, a few sessions of these devices would be a viable option for acne treatments. PMID- 29178496 TI - Kisspeptin, gonadotrophin-releasing hormone and oestrogen receptor alpha colocalise with neuronal nitric oxide synthase neurones in prepubertal female sheep. AB - Puberty is a process that integrates multiple inputs ultimately resulting in an increase in gonadotrophin-releasing hormone (GnRH) secretion. Although kisspeptin neurones play an integral role in GnRH secretion and puberty onset, other systems are also likely important. One potential component is nitric oxide (NO), a gaseous neurotransmitter synthesised by nitric oxide synthase (NOS). The present study aimed to neuroanatomically characterise neuronal NOS (nNOS) in prepubertal female sheep and determine whether oestradiol exerts effects on this system. Luteinising hormone secretion was reduced by oestradiol treatment in prepubertal ovariectomised ewes. Neurones immunoreactive for nNOS were identified in several areas, with the greatest number present in the ventrolateral portion of the ventromedial hypothalamus, followed by the ventromedial hypothalamus, preoptic area (POA) and arcuate nucleus (ARC). Next, we determined whether nNOS neurones contained oestrogen receptor (ER)alpha and could potentially communicate oestradiol (E2 ) feedback to GnRH neurones. Neuronal NOS neurones contained ERalpha with the percentage of coexpression (12%-40%) depending upon the area analysed. We next investigated whether a neuroanatomical relationship existed between nNOS and kisspeptin or nNOS and GnRH neurones. A high percentage of kisspeptin neurones in the POA (79%) and ARC (98%) colocalised with nNOS. Kisspeptin close contacts were also associated with nNOS neurones. A greater number of close contacts were observed in the ARC than the POA. A high percentage of POA GnRH neurones (79%) also expressed nNOS, although no GnRH close contacts were observed onto nNOS neurones. Neither the numbers of nNOS neurones in the POA or hypothalamus, nor the percentage of nNOS coexpression with GnRH, kisspeptin or ERalpha were influenced by oestradiol. These experiments reveal that a neuroanatomical relationship exists between both nNOS and kisspeptin and nNOS and GnRH in prepubertal ewes. Therefore, nNOS may act both directly and indirectly to influence GnRH secretion in prepubertal sheep. PMID- 29178497 TI - How to perform posterior wall isolation in catheter ablation for atrial fibrillation. AB - Catheter ablation has become standard of care in patients with symptomatic atrial fibrillation (AF). Although there have been significant advances in our understanding and technology, a substantial proportion of patients have ongoing AF requiring repeat procedures. Pulmonary vein isolation (PVI) is the cornerstone of AF ablation; however, it is less effective in patients with persistent as opposed to paroxysmal atrial fibrillation. Left atrial posterior wall isolation (PWI) is commonly performed as an adjunct to PVI in patients with persistent AF with nonrandomized studies showing improved outcomes. Anatomical considerations and detailed outline of the various approaches and techniques to performing PWI are detailed, and advantages and pitfalls to assist the clinical electrophysiologist successfully and safely complete PWI are described. PMID- 29178498 TI - Technical Note: Solving the "Chinese postman problem" for effective contour deformation. AB - PURPOSE: To develop a practical approach for accurate contour deformation when deformable image registration (DIR) is used for atlas-based segmentation or contour propagation in image-guided radiotherapy. METHODS: We developed a contour deformation approach based on 3D mesh operations. The 2D contours represented by a series of points in each slice were first converted to a 3D triangular mesh, which was deformed by the deformation vectors resulting from DIR. A set of parallel 2D planes then cut through the deformed 3D mesh, generating unordered points and line segments, to be reorganized into a set of 2D contour points. The reorganization problem was equivalent to solving the "Chinese postman problem" (CPP) by traversing a graph built from the unordered points with the least cost. Alternatively, deformation could be applied to a binary image converted from the original contours. The deformed binary image was then converted back into contours at the CT slice locations. We validated the mesh-based contour deformation approach using lung and heart contours from 10 patients with thoracic cancer. RESULTS: DIR could change the 3D mesh considerably, complicating 2D contour representations after deformation. CPP could effectively reorganize the points in 2D planes regardless of how complicated the 2D contours were. Among the 10 patients, the Dice similarity coefficient between the mesh-based contour and binary image-based contour was 97.6% +/- 0.3% for lung and 97.5% +/- 0.7% for heart, and the Hausdoroff distance between them was 19.8 +/- 5.1 mm for lung and 6.1 +/- 2.2 mm for heart. Subjective evaluation showed that the mesh-based approach could keep fine details, especially for the lung. The image-based approach seemed to overprocess contours and suffered from image resolution limits. CONCLUSION: We developed a practical approach for accurate contour deformation and demonstrated its effectiveness for both clinical and research applications. PMID- 29178499 TI - AANEM policy statement on electrodiagnosis for distal symmetric polyneuropathy. AB - Electrodiagnostic (EDX) studies are often very helpful in the diagnosis and management of patients who have or are suspected to have Distal Symmetric Polyneuropathy (DSP). However, EDX studies may not be appropriate in every situation. There are five common scenarios in which EDX studies are likely to be beneficial: (1) determining primary and alternative diagnoses; (2) determining severity, duration and prognosis of disease; (3) evaluating risk of associated problems; (4) determining the effect of medications; and (5) evaluating the effect of toxic exposures. Muscle Nerve 57: 337-339, 2018. PMID- 29178500 TI - Identifying unique subtypes of spinal afferent nerve endings within the urinary bladder of mice. AB - Spinal afferent neurons are responsible for the transduction and transmission of noxious (painful) stimuli and innocuous stimuli that do not reach conscious sensations from visceral organs to the central nervous system. Although the location of the nerve cell bodies of spinal afferents is well known to reside in dorsal root ganglia (DRG), the morphology and location of peripheral nerve endings of spinal afferents that transduce sensory stimuli into action potentials is poorly understood. The individual nerve endings of spinal afferents that innervate the urinary bladder have never been unequivocally identified in any species. We used an anterograde tracing technique developed in our laboratory to selectively label only spinal afferents. Mice were anesthetized and unilateral injections of dextran-amine made into lumbosacral DRGs (L5-S2). Seven to nine days postsurgery, mice were euthanized, the urinary bladder removed, then fresh fixed and stained for immunoreactivity to calcitonin-gene-related-peptide (CGRP). Four distinct morphological types of spinal afferent ending in the bladder were identified. Three types existed in the detrusor muscle and one major type in the sub-urothelium and urothelium. Most nerve endings were located in detrusor muscle where the three types could be identified as having: "branching", "simple", or "complex" morphology. The majority of spinal afferent nerve endings were CGRP immunoreactive. Single spinal afferent axons bifurcated many times upon entering the bladder and developed varicosities along their axon terminal endings. We present the first morphological identification of spinal afferent nerve endings in the mammalian urinary bladder. PMID- 29178501 TI - In vivo reflectance confocal microscopy image interpretation for the dermatopathologist. AB - Reflectance confocal microscopy (RCM) is a technology utilized for bedside diagnosis of cutaneous pathology by non-invasive, in vivo, cellular-level imaging. With the recent establishment of reimbursement codes by the US Centers for Medicaid and Medicare Services, RCM is now likely to be employed by clinical dermatologists and impact decision making on skin cancer management. Dermatopathologists, therefore, would benefit from learning how to interpret RCM images and how RCM findings correlate with histopathological criteria of diagnosis. This review briefly explains the principles behind RCM image acquisition, describes the key RCM features of normal skin, and delineates the RCM characteristics of frequently observed benign and malignant neoplasms. PMID- 29178502 TI - Survival times with and without tube feeding in patients with dementia or psychiatric diseases in Japan. AB - BACKGROUND: It is widely supposed that there has been no evidence of increased survival in patients with advanced dementia receiving enteral tube feeding. However, more than a few studies have reported no harmful outcome from tube feeding in dementia patients compared to in patients without dementia. METHODS: This was a retrospective study. Nine psychiatric hospitals in Okayama Prefecture participated in this survey. All inpatients fulfilling the entry criteria were evaluated. All subjects suffered from difficulty with oral intake. Attending physicians thought that the patients could not live without long-term artificial nutrition. The physicians decided whether to make use of long-term artificial nutrition between January 2012 and December 2014. RESULTS: We evaluated 185 patients. Their mean age was 76.6 +/- 11.4 years. Of all subjects, patients with probable Alzheimer's disease (n = 78) formed the biggest group, schizophrenia patients (n = 44) the second, and those with vascular dementia (n = 30) the third. The median survival times were 711 days for patients with tube feeding and 61 days for patients without tube feeding. In a comparison different types of tube feeding, median survival times were 611 days for patients with a nasogastric tube and more than 1000 days for those with a percutaneous endoscopic gastrostomy tube. CONCLUSION: Patients with tube feeding survived longer than those without tube feeding, even among dementia patients. This study suggests that enteral nutrition for patients with dementia prolongs survival. Additionally, percutaneous endoscopic gastrostomy tube feeding may be safer than nasogastric tube feeding among patients in psychiatric hospitals. PMID- 29178504 TI - Spontaneous left atrial echo contrast, mitral annular systolic velocity, and left atrial appendage late emptying velocity in predicting improvement of left atrial function after percutaneous balloon mitral valvuloplasty. AB - BACKGROUND: Thromboembolic events are the major cause of morbidity and mortality in patients with mitral stenosis (MS). This study aims to investigate left atrial spontaneous echo contrast (LA SEC), mitral annular systolic velocity (Sa-wave), left atrial appendage (LAA) late emptying velocity (LAAEV), LAA filling velocity (LAAFV) pre- and postpercutaneous balloon mitral valvuloplasty (PBMV) for MS. This also aims to study the association of LA SEC with inflammatory marker, high sensitivity C-reactive protein (hs-CRP) in MS. METHODS: The study population consisted of 100 patients with symptomatic MS with sinus rhythm who underwent PBMV. Transthoracic echo (TTE), tissue Doppler imaging (TDI), and transesophageal echo (TEE) examinations were carried out before and 14 days following PBMV. High sensitivity C-reactive protein (hs-CRP) was measured at the time of admission. RESULTS: The mean age was 33.2 +/- 10.3 years with female preponderance (71%). There was a decrease in SEC grading, (pre-PBMV 2.8 +/- 0.9 and post-PBMV 0.4 +/- 0.1; P < .01), increase in LAAEV (pre-PBMV 23.0 +/- 7.9 cm/s and post-PBMV 40.9 +/- 8.4 cm/s; P < .01), and LAAFV (pre-PBMV 31.8 +/- 9.3 cm/s and post-PBMV 51.2 +/- 8.7 cm/s; P < .01).A significant positive correlation was present between LAAEV and Sa-wave (r = .52, P < .01). Correlation between hs-CRP and SEC was positive and significant (r = .33, P < .01). Optimal cutoff value of hs-CRP for prediction of moderate to dense SEC was >2.3 mg/dL, the cutoff value of Sa-wave was<= 5.5 cm/s for prediction of the presence of inactive LAA (LAAEV < 25 cm/s). CONCLUSION: Mitral annular systolic velocity (Sa-wave) is an independent predictor of inactive LAA and a useful parameter in estimating inactive LAA in MS. Sa-wave and hs-CRP are independent predictors for SEC. PBMV improves LAA function in patients with MS. PMID- 29178505 TI - Expression levels of taste-related genes in palate and tongue tip, and involvement of transient receptor potential subfamily M member 5 (TRPM5) in taste sense in chickens. AB - The elucidation of the mechanisms underlying the taste sense of chickens will contribute to improvements in poultry feeding, because the molecular mechanism of chickens' taste sense defines the feeding behavior of chickens. Here we focused on the gene expressions in two different oral tissues of chickens - the palate, which contains many taste buds, and the tongue tip, which contains few taste buds. Using the quantitative real-time polymerase chain reaction method, we found that the molecular markers for taste buds of chickens, that is alpha-gustducin and vimentin, were expressed significantly highly in the palate compared to the tongue tip. Our analyses also revealed that transient receptor potential subfamily M member 5 (TRPM5), a cation channel involved in taste transduction in mammals, was also highly expressed in the palate compared to the tongue tip. Our findings demonstrated that the expression patterns of these genes were significantly correlated. We showed that the aversion to bitter solution was alleviated by a TRPM5 inhibitor in behavior of chickens. Taken together, our findings enabled us to develop a simple method for screening taste-related genes in chickens. The use of this method demonstrated that TRPM5 was involved in chickens' taste transduction, and that a TRPM5 inhibitor can alleviate chickens' bitter taste perception of feed ingredients. PMID- 29178506 TI - Complications and short-term outcomes associated with single-port laparoscopic splenectomy in dogs. AB - OBJECTIVE: To describe a technique and report complications and outcome for single-port laparoscopic splenectomy in dogs. STUDY DESIGN: Retrospective study. ANIMALS: Twenty-two client-owned dogs. METHODS: Medical records of dogs that underwent single-port laparoscopic splenectomy at 4 veterinary teaching hospitals were evaluated. Commercially available single-port devices were used in all dogs. In all cases, a vessel-sealing device was used to perform a hilar splenectomy. After the procedure was completed, the spleen was exteriorized through the single port device incision or placed into a specimen retrieval device; enlargement of the incision was required in some cases. RESULTS: Median weight of dogs was 9.9 kg (interquartile range [IQR], 7.0-26.0). Splenectomy was performed because of splenic mass (n = 14), diffuse splenic disease (n = 4), or as adjunctive treatment for management of immune-mediated disease (n = 4). In cases with splenic masses, median maximal diameter of the largest splenic mass was 2.0 cm (IQR, 1.3-2.5). In 6 of 22 cases, mild splenic capsular bleeding occurred during the procedure. Conversion occurred in 6 of 22 cases to either a laparoscopic assisted approach (n = 5) or an open celiotomy (n = 1). Reasons for conversion included large splenic dimensions (n = 3), adhesion formation (n = 1) or poor visualization resulting from abundant intra-abdominal fat (n = 1) or hemorrhage (n = 1). Heavier body weight was significantly associated with conversion (odds ratio, 1.62; 95% confidence interval, 1.05-2.51), but body condition score, having a splenic mass, splenic mass size, and surgical time were not. CONCLUSION: Single-port laparoscopic splenectomy is an effective approach for elective splenectomy in dogs. The technique may be well suited to smaller dogs with modestly sized splenic masses or diffuse splenic disease. PMID- 29178507 TI - Is Doppler ultrasonography of value for the differentiation between noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) and invasive encapsulated follicular variant of papillary thyroid carcinoma? PMID- 29178508 TI - Predictive accuracy of combined genetic and environmental risk scores. AB - The substantial heritability of most complex diseases suggests that genetic data could provide useful risk prediction. To date the performance of genetic risk scores has fallen short of the potential implied by heritability, but this can be explained by insufficient sample sizes for estimating highly polygenic models. When risk predictors already exist based on environment or lifestyle, two key questions are to what extent can they be improved by adding genetic information, and what is the ultimate potential of combined genetic and environmental risk scores? Here, we extend previous work on the predictive accuracy of polygenic scores to allow for an environmental score that may be correlated with the polygenic score, for example when the environmental factors mediate the genetic risk. We derive common measures of predictive accuracy and improvement as functions of the training sample size, chip heritabilities of disease and environmental score, and genetic correlation between disease and environmental risk factors. We consider simple addition of the two scores and a weighted sum that accounts for their correlation. Using examples from studies of cardiovascular disease and breast cancer, we show that improvements in discrimination are generally small but reasonable degrees of reclassification could be obtained with current sample sizes. Correlation between genetic and environmental scores has only minor effects on numerical results in realistic scenarios. In the longer term, as the accuracy of polygenic scores improves they will come to dominate the predictive accuracy compared to environmental scores. PMID- 29178509 TI - Oral immunization with a Lactobacillus casei-based anti-porcine epidemic diarrhoea virus (PEDV) vaccine expressing microfold cell-targeting peptide Co1 fused with the COE antigen of PEDV. AB - AIMS: The aims of this study were to develop an effective M cell-targeting oral vaccine, involving Lactobacillus casei to deliver the porcine epidemic diarrhoea virus (PEDV) core neutralizing epitope (COE) antigen conjugated with M cell targeting peptide Co1 as an adjuvant, against PEDV infection. METHODS AND RESULTS: Genetically engineered L. casei 393 (L393) strains expressing PEDV COE antigen only (pPG-COE/L393) or fused-expressing COE and M cell-targeting peptide Co1 (pPG-COE-Co1/L393) were constructed, and the immunogenicity upon administration as an oral vaccine was evaluated. The results showed that higher anti-PEDV serum IgG and mucosal SIgA antibody responses were induced in mice orally immunized with strain pPG-COE-Co1/L393 as compared to the mice immunized with strain L393 expressing COE alone or carrying the empty plasmid. In addition, the use of the Co1 ligand elicited a splenocyte proliferative response more effectively in comparison with the COE antigen alone and supported a skewed T helper 2 type of immune response against PEDV. CONCLUSIONS: pPG-COE-Co1/L393 can effectively induce mucosal, humoural and Th2-type cellular immune responses against PEDV infection via oral administration. Furthermore, M cell-targeting peptide ligand Co1 is a good mucosal adjuvant. SIGNIFICANCE AND IMPACT OF THE STUDY: Lactobacillus casei delivering the COE antigen of PEDV conjugated with a M cell-targeting peptide Co1 as an immune adjuvant is a promising oral vaccine candidate for PEDV. PMID- 29178510 TI - The pathogenesis of hemodialysis vascular access failure and systemic therapies for its prevention: Optimism unfulfilled. AB - In patients receiving hemodialysis, the provision of safe and effective vascular access using an arteriovenous fistula or graft is regarded as a critical priority by patients and health professionals. Vascular access failure is associated with morbidity and mortality, such that strategies to prevent these outcomes are essential. Inadequate vascular remodeling and neointimal hyperplasia resulting in stenosis and frequently thrombosis are critical to the pathogenesis of access failure. Systemic medical therapies with pleiotropic effects including antiplatelet agents, omega-3 polyunsaturated fatty acids (fish oils), statins, and inhibitors of the renin-angiotensin-aldosterone system (RAAS) may reduce vascular access failure by promoting vascular access maturation and reducing stenosis and thrombosis through antiproliferative, antiaggregatory, anti inflammatory and vasodilatory effects. Despite such promise, the results of retrospective analyses and randomized controlled trials of these agents on arteriovenous fistula and graft outcomes have been mixed. This review describes the current understanding of the pathogenesis of arteriovenous fistula and graft failure, the biological effects of antiplatelet agents, fish oil supplementation, RAAS blockers and statins that may be beneficial in improving vascular access survival, results from clinical trials that have investigated the effect of these agents on arteriovenous fistula and graft outcomes, and it explores future therapeutic approaches combining these agents with novel treatment strategies. PMID- 29178511 TI - Neurostimulation for Refractory Cervicogenic Headache: A Three-Year Retrospective Study. AB - BACKGROUND: Occipital nerve stimulation (ONS) has been used for the treatment of neuropathic pain conditions and could be a therapeutic approach for refractory cervicogenic headache (CeH). AIM: The aim of this study is to assess the efficacy and safety of unilateral ONS in patients suffering from refractory CeH. METHODS: We conducted a retrospective chart review on patients implanted from 2011 to 2013 at CHUM. The primary outcome was a 50% reduction in headache days per month. Secondary outcomes included change in EuroQol Group Visual Analog Scale rating of health-related quality of life (EQ VAS), six item headache impact test (HIT-6) score, hospital anxiety and depression scale (HADS) score, work status, and medication overuse. RESULTS: Sixteen patients fulfilled the inclusion criteria; they had suffered from daily moderate to severe CeH for a median of 15 years. At one year follow-up, 11 patients were responders (69%). There was a statistically significant improvement in the EQ VAS score (median change: 40 point increase, p = 0.0013) and HIT-6 score (median change: 17.5 point decrease, p = 0.0005). Clinically significant anxiety and depression scores both resolved amongst 60% of patients. At three years, six patients were responders (37.5%). Out of the 11 responders at one-year post implantation, five had remained headache responders (R-R) and one additional patient became a responder (NR-R). There was a statistically significant improvement in the EQ VAS score (median change: 15 point increase, p = 0.019) and HIT-6 score (median change: 7.5 point decrease, p = 0.0017) compared with baseline. Clinically significant anxiety and depression scores both, respectively, resolved among 22.5% and 33.9% of patients. Five out of seven disabled patients were back to work. CONCLUSION: ONS may be a safe and effective treatment modality for patients suffering from a refractory CeH. Further study may be warranted. PMID- 29178512 TI - Body size and risk of atrial fibrillation: a cohort study of 1.1 million young men. AB - BACKGROUND: Whilst tall stature has been related to lower risk of vascular disease, it has been proposed as a risk factor for atrial fibrillation. Little is known about other anthropometric measures and their joint effects on risk of atrial fibrillation. OBJECTIVES: We aim to investigate associations and potential joint effects of height, weight, body surface area (BSA) and body mass index (BMI) with risk of atrial fibrillation. METHODS: In a cohort covering 1 153 151 18-year-old men participating in the Swedish military conscription (1972-1995), Cox regression was used to investigate associations of height, weight, BSA and BMI with risk of atrial fibrillation. RESULTS: During a median of 26.3 years of follow-up, higher height was associated with higher risk of atrial fibrillation (hazard ratio [HR] 2.80; 95% CI 2.63-2.98; for 5th vs. 1st quintile) and so was larger BSA (HR 3.05; 95% CI 2.82-3.28; for 5th vs. 1st quintile). Higher weight and BMI were to a lesser extent associated with risk of atrial fibrillation (BMI: 1.42; 95% CI 1.33-1.52, for 5th vs. 1st quintile). We found a multiplicative joint effect of height and weight. Adjusting for muscle strength, exercise capacity and diseases related to atrial fibrillation attenuated these measures. CONCLUSIONS: Higher height and weight are strongly associated with higher risk of atrial fibrillation. These associations are multiplicative and independent of each other and are summarized in a strong association of body surface area with risk of atrial fibrillation. The mechanisms remain unknown but may involve increased atrial volume load with larger body size. PMID- 29178513 TI - Relationship Between Neonatal Vitamin D at Birth and Risk of Autism Spectrum Disorders: the NBSIB Study. AB - Previous studies suggested that lower vitamin D might be a risk factor for autism spectrum disorders (ASDs). The aim of this study was to estimate the prevalence of ASDs in 3-year-old Chinese children and to examine the association between neonatal vitamin D status and risk of ASDs. We conducted a study of live births who had taken part in expanded newborn screening (NBS), with outpatient follow-up when the children 3-year old. The children were confirmed for ASDs in outpatient by the Autism Diagnostic Interview-Revised and Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 criteria. Intellectual disability (ID) status was defined by the intelligence quotient (IQ < 80) for all the participants. The study design included a 1:4 case to control design. The concentration of 25 hydroxyvitamin D3 [25(OH)D3] in children with ASD and controls were assessed from neonatal dried blood samples. A total of 310 children were diagnosed as having ASDs; thus, the prevalence was 1.11% (95% CI, 0.99% to 1.23%). The concentration of 25(OH)D3 in 310 ASD and 1240 controls were assessed. The median 25(OH)D3 level was significantly lower in children with ASD as compared to controls (p < 0.0001). Compared with the fourth quartiles, the relative risk (RR) of ASDs was significantly increased for neonates in each of the three lower quartiles of the distribution of 25(OH)D3, and increased risk of ASDs by 260% (RR for lowest quartile: 3.6; 95% CI, 1.8 to 7.2; p < 0.001), 150% (RR for second quartile: 2.5; 95% CI, 1.4 to 3.5; p = 0.024), and 90% (RR for third quartile: 1.9; 95% CI, 1.1 to 3.3; p = 0.08), respectively. Furthermore, the nonlinear nature of the ID-risk relationship was more prominent when the data were assessed in deciles. This model predicted the lowest relative risk of ID in the 72rd percentile (corresponding to 48.1 nmol/L of 25(OH)D3). Neonatal vitamin D status was significantly associated with the risk of ASDs and intellectual disability. The nature of those relationships was nonlinear.

AB - Separation of gas molecules with similar physical and chemical properties is challenging but nevertheless highly relevant for chemical processing. By introducing the elliptically shaped molecule, 1,4-dimethyl-1,4 diazabicyclo[2.2.2]octane, into the interlayer space of a layered silicate, a two dimensional microporous network with narrow pore size distribution is generated (MOPS-5). The regular arrangement of the pillar molecules in MOPS-5 was confirmed by the occurrence of a 10 band related to a long-range pseudo-hexagonal superstructure of pillar molecules in the interlayer space. Whereas with MOPS-5 for CO2 adsorption, gate-opening occurs at constant volume by freezing pillar rotation, for CO the interlayer space is expanded at gate-opening and a classical interdigitated layer type of gate-opening is observed. The selective nature of the gate-opening might be used for separation of CO and N2 by pressure swing adsorption.

AB - Atopic dermatitis (AD) is a chronic and multifactorial inflammatory skin disease involving various dendritic cells such as epidermal Langerhans cells (LC) and inflammatory dendritic epidermal cells (IDECs). Most of the clinical studies was performed on isolated cells, and thus, it would be useful to characterize directly on the human epidermal tissue the first cellular events occurred during the AD. The suction blister method was used to obtain whole epidermis samples and interstitial cutaneous fluids. Employing multiphoton microscopy, we analyzed the early dynamic behavior of inflammatory cells using Dermatophagoides pteronyssinus atopy patch test (Derp-APT) and evaluated the effects of emollient pre application. Derp-APT application provoked rapid and strong infiltration of IDECs, and proliferation and activation of LC in the AD subjects' epidermis. Moreover, emollient pre-application strengthened the defective skin barrier and had positive effects on inflammatory cells' behavior, characterized by the complete inhibition of IDEC influx and the presence of immature LC. PMID- 29178516 TI - Nicotinamide phosphoribosyltransferase delays cellular senescence by upregulating SIRT1 activity and antioxidant gene expression in mouse cells. AB - Senescent cells accumulate in tissues of aged animals and deteriorate tissue functions. The elimination of senescent cells from aged mice not only attenuates progression of already established age-related disorders, but also extends median lifespan. Nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme in mammalian NAD+ salvage pathway, has shown a protective effect on cellular senescence of human primary cells. However, it still remains unclear how NAMPT has a protective impact on aging in vitro and in vivo. In this study, we found that primary mouse embryonic fibroblast (MEF) cells undergo progressive decline of NAMPT and NAD+ contents during serial passaging before becoming senescent. Furthermore, we showed that constitutive Nampt over-expression increases cellular NAD+ content and delays cellular senescence of MEF cells in vitro. We further found that constitutive Nampt over-expression increases SIRT1 activity, increases the expression of antioxidant genes, superoxide dismutase 2 and catalase and promotes resistance against oxidative stress. These findings suggest that Nampt over-expression in MEF cells delays cellular senescence by the mitigation of oxidative stress via the upregulation of superoxide dismutase 2 and catalase gene expressions by SIRT1 activation. PMID- 29178517 TI - Women's attractiveness is linked to expected age at menopause. AB - A great number of studies have shown that features linked to immediate fertility explain a large part of the variance in female attractiveness. This is consistent with an evolutionary perspective, as men are expected to prefer females at the age at which fertility peaks (at least for short-term relationships) in order to increase their reproductive success. However, for long-term relationships, a high residual reproductive value (the expected future reproductive output, linked to age at menopause) becomes relevant as well. In that case, young age and late menopause are expected to be preferred by men. However, the extent to which facial features provide cues to the likely age at menopause has never been investigated so far. Here, we show that expected age at menopause is linked to facial attractiveness of young women. As age at menopause is heritable, we used the mother's age at menopause as a proxy for her daughter's expected age of menopause. We found that men judged faces of women with a later expected age at menopause as more attractive than those of women with an earlier expected age at menopause. This result holds when age, cues of immediate fertility and facial ageing were controlled for. Additionally, we found that the expected age at menopause was not correlated with any of the other variables considered (including immediate fertility cues and facial ageing). Our results show the existence of a new correlate of women's facial attractiveness, expected age at menopause, which is independent of immediate fertility cues and facial ageing. PMID- 29178518 TI - Low annual frequency of HbA1c testing in people with Type 2 diabetes in primary care practices in Germany. AB - AIMS: To analyse the annual frequency of HbA1c testing, as well as the factors associated with higher or lower testing frequency, in people with Type 2 diabetes mellitus in general practices and specialist diabetes practices in Germany. METHODS: A total of 43 509 people diagnosed with Type 2 diabetes between January 2016 and December 2016 in 557 medical practices (51% of all practices) were included in this study. The primary outcome was the annual recorded frequency of HbA1c testing in 2016. Multivariable logistic regression analyses were performed to identify variables associated with the odds of HbA1c concentration being tested at least twice in 2016, using predefined demographic and clinical variables. RESULTS: The mean (sd) number of reported HbA1c tests was 2.7 (1.6) in 2016. Overall, 74% of individuals had at least two annual HbA1c measurements. The likelihood of receiving >=2 HbA1c tests was inversely associated with stroke (odds ratio 0.81, 95% CI 0.74-0.89), shorter diabetes duration (<=1 year: odds ratio 0.77, 95% CI 0.70-0.84) and higher mean HbA1c concentration (>=8.5%: odds ratio 0.85, 95% CI 0.76-0.94) and was positively associated with specialist diabetes care (odds ratio 1.24, 95% CI 1.14-1.36), hypertension (odds ratio 1.10, 95% CI 1.04-1.17), hyperlipidaemia (odds ratio 1.48, 95% CI 1.41 to 1.55), renal complications (odds ratio 1.41, 95% CI 1.32 to 1.50), neuropathy (odds ratio 1.27, CI 1.20 to 1.35) and retinopathy (odds ratio 1.38, 95% CI 1.25 to 1.52). CONCLUSIONS: Only three out of four individuals with Type 2 diabetes underwent at least two HbA1c tests in Germany in 2016, which means that 25% of individuals underwent fewer tests than required by German guidelines. PMID- 29178519 TI - Semaglutide, reduction in glycated haemoglobin and the risk of diabetic retinopathy. AB - AIMS: To evaluate diabetic retinopathy (DR) data from across the SUSTAIN clinical trial programme. MATERIALS AND METHODS: The SUSTAIN clinical trial programme evaluated the efficacy and safety of semaglutide, a glucagon-like peptide-1 analogue, for the treatment of type 2 diabetes (T2D). In SUSTAIN 6, a 2-year, pre approval cardiovascular outcomes trial, semaglutide was associated with a significant increase in the risk of DR complications (DRC) vs placebo. DR data from across the SUSTAIN trials were evaluated, and post hoc analyses of the SUSTAIN 6 data were conducted. These included subgroup analyses to identify at risk patients and a mediation analysis with initial change in glycated haemoglobin (HbA1c; percentage-points at week 16) as a covariate, to examine the role of the magnitude of reduction in HbA1c as an intermediate factor affecting risk of DRC. RESULTS: There was no imbalance in DR adverse events across the SUSTAIN 1 to 5 and Japanese trials. The majority of the effect with semaglutide vs placebo in SUSTAIN 6 may be attributed to the magnitude and rapidity of HbA1c reduction during the first 16 weeks of treatment in patients who had pre-existing DR and poor glycaemic control at baseline, and who were treated with insulin. CONCLUSIONS: Early worsening of DR is a known phenomenon associated with the rapidity and magnitude of improvement in glycaemic control with insulin; the DRC findings in SUSTAIN 6 are consistent with this. Guidance regarding the early worsening of DR is recommended with insulin. Similar recommendations may be appropriate for semaglutide. PMID- 29178520 TI - A catch-22: Interleukin-22 and cancer. AB - Barrier surfaces of multicellular organisms are in constant contact with the environment and infractions to the integrity of epithelial surfaces is likely a frequent event. Interestingly, components of the immune system, that can be activated by environmental compounds such as the microbiota or nutrients, are interspersed among epithelial cells or directly underlie the epithelium. It is now appreciated that immune cells continuously receive and integrate signals from the environment. Curiously, such continuous reception of stimulation does not normally trigger an inflammatory response but mediators produced by immune cells in response to such signals seem to rather promote barrier integrity and repair. The molecular mediators involved in this process are poorly understood. In recent years, the cytokine interleukin-22, produced mainly by group 3 innate lymphoid cells (ILCs), has been studied as a paradigm for how immune cells can control various aspects of epithelial cell function because expression of its receptor is restricted to non-hematopoietic cells. We will summarize here the diverse roles of IL-22 for the malignant transformation of epithelial cells, for tumor growth, wound healing and tissue repair. Furthermore, we will discuss IL-22 as a potential therapeutic target. PMID- 29178521 TI - Multiple Routes to Smart Nanostructured Materials from Diatom Microalgae: A Chemical Perspective. AB - Diatoms are unicellular photosynthetic microalgae, ubiquitously diffused in both marine and freshwater environments, which exist worldwide with more than 100 000 species, each with different morphologies and dimensions, but typically ranging from 10 to 200 um. A special feature of diatoms is their production of siliceous micro- to nanoporous cell walls, the frustules, whose hierarchical organization of silica layers produces extraordinarily intricate pore patterns. Due to the high surface area, mechanical resistance, unique optical features, and biocompatibility, a number of applications of diatom frustules have been investigated in photonics, sensing, optoelectronics, biomedicine, and energy conversion and storage. Current progress in diatom-based nanotechnology relies primarily on the availability of various strategies to isolate frustules, retaining their morphological features, and modify their chemical composition for applications that are not restricted to those of the bare biosilica produced by diatoms. Chemical or biological methods that decorate, integrate, convert, or mimic diatoms' biosilica shells while preserving their structural features represent powerful tools in developing scalable, low-cost routes to a wide variety of nanostructured smart materials. Here, the different approaches to chemical modification as the basis for the description of applications relating to the different materials thus obtained are presented. PMID- 29178522 TI - Direct hyperbilirubinemia in infants with congenital heart disease. AB - BACKGROUND: The association between congenital heart disease (CHD) and infantile cholestasis, a key finding for the diagnosis of biliary atresia (BA), has not been previously investigated. The aim of this study was therefore to investigate the characteristics of direct hyperbilirubinemia (D-HB) in infants with CHD. METHODS: All neonates admitted to the present hospital and diagnosed with CHD in 2015 and 2016 were included. D-HB (direct bilirubin >= 2.0 mg/dL) at <=60 days of age and other clinical parameters were retrospectively reviewed. Statistical analysis according to presence of D-HB was performed using chi-squared test or Wilcoxon rank sum test. RESULTS: Seventy-six patients (M:F, 36:40) were included in this study. CHD consisted of ventricular septal defect in 17, patent ductus arteriosus in 10, and other in 49. Thirteen patients (17.1%) had D-HB at <=60 days of age. Resolution of D-HB (DB < 2.0 mg/dL) occurred in 10 of the 13 patients during the hospital stay, and this occurred in <=7 days in eight of the 10 patients. Sex, gestational age, birthweight, chromosomal anomalies, need for Fontan operation for CHD repair, and/or cardiac operation were not associated with D-HB at <=60 days of age. CONCLUSION: While D-HB was frequently observed in infants with CHD, the majority of D-HB cases resolved spontaneously in <=1 week. Neonatal clinical parameters or CHD status was not predictive of D-HB. D-HB lasting >1 week in infants with CHD should be evaluated for the cause.

PMID- 29178524 TI - Exposure to Trauma and Mental Health Service Engagement Among Adults Who Were Children of the Northern Ireland Troubles of 1968 to 1998. AB - Northern Ireland is an appropriate region to examine the impact of traumatic experiences, owing to the many years of civil violence that have characterized its recent history, known colloquially as the "Troubles." Given the prominence of traumatic experiences among the aging population of Northern Ireland (NI), an evidence base is required to inform the planning and provision of effective mental health and other services. We analyzed the follow-up interviews (n = 225) of individuals from the Northern Ireland Study of Health and Stress (NISHS), aged 45 years and older, who experienced one or more conflict-related traumatic events. This study demonstrated that in NI traumatic events, such as being involved in an explosion, seeing someone killed or seriously injured, and living in a region of terror were most likely to be related to the Troubles. However, event types that we had not previously known to be related to conflict (such as the sudden death of a loved one), were also often related to the Troubles. Two thirds of participants (67.1%) reported exposure to a Troubles-related event, and 57.8% reported being a civilian in a region of terror. The vast majority (85.9%) of participants who experienced a Troubles-related trauma never sought help, despite 59.1% meeting the criteria for a lifetime mental disorder. The reasons for not seeking help and sources of help are outlined. Policy makers must address Troubles-related mental health effects, in terms of how they carry forward into aging, and consider ways of improving engagement with services and treatments. PMID- 29178525 TI - Flow dynamics of cerebrospinal fluid between the intracranial cavity and the subarachnoid space of the optic nerve measured with a diffusion magnetic resonance imaging sequence in patients with normal tension glaucoma. AB - IMPORTANCE: This study offers a new approach for the quantification of CSF dynamics. BACKGROUND: Non-invasive method to quantify the CSF dynamics in the subarachnoid space of the optic nerve is highly desirable. The aim of the study was to measure slow-flow CSF velocities in healthy controls and normal tension glaucoma patients between the intracranial cavity and the subarachnoid space of the optic nerve. DESIGN: Prospective observational study. PARTICIPANTS: Eleven age-matched healthy volunteers and 15 normal tension glaucoma patients. METHODS: Using phase contrast images, the phase shift in MRI diffusion images can be used to determine the flow velocity. Flow-range ratio between the intracranial cavity and the subarachnoid space of the optic nerve was calculated. MAIN OUTCOME MEASURE: Flow-range ratio between the intracranial cavity and the subarachnoid space of the optic nerve was calculated. RESULTS: First, phantom measurements were provided to validate the slow-flow velocity calculations. Second, flow-range ratio was validated for the healthy controls (0.63 +/- 0.05), with the range being similar for the right and left optic nerve (P = 0.1). Statistically significant results were obtained (P < 0.05) when comparing the flow-range ratio in the optic nerve of healthy controls (n = 22 eyes, 0.63 +/- 0.05) with the flow range ratio in pathological optic nerves (n = 23, 0.55 +/- 0.08) of normal tension glaucoma patients. MANOVA revealed no dependency between flow-range ratio and patient dependent variables. CONCLUSION AND RELEVANCE: Diffusion-weighted imaging provides a method to evaluate CSF flow within the subarachnoid space of the optic nerve in a non-invasive manner. Compared to healthy controls, patients with normal tension glaucoma measure a significantly lower flow-range ratio. This finding suggests a possible role of impaired CSF dynamics in the pathophysiology in normal tension glaucoma. PMID- 29178526 TI - Rapid characterization of nonpolar or low-polarity solvent extracts from herbal medicines by solvent-assisted electrospray ionization mass spectrometry. AB - RATIONALE: The direct detection of nonpolar and low-polarity solvent extracts of herbal medicine is difficult by conventional electrospray ionization mass spectrometry (ESI-MS). This problem can be solved by solvent-assisted electrospray ionization mass spectrometry (SAESI-MS). With the help of assisted solvents (ESI-friendly solvents) at the tip of the spray needle, compounds (especially the low-polarity compounds) in nonpolar and low-polarity solvent extracts can be ionized directly. METHODS: Herbal medicines were ultrasonically extracted with nonpolar or low-polarity solvents, such as petroleum ether. Thereafter, the extracts were analyzed by conventional ESI-MS, atmospheric pressure chemical ionization mass spectrometry (APCI-MS) and SAESI-MS. The mass spectra obtained from these three methods were compared and analyzed. RESULTS: Unstable ion signals, and even no ion signals, were observed when the nonpolar and low-polarity solvent extracts were detected directly by conventional ESI-MS. Better specificity, higher sensitivity or cleaner spectra were acquired from SAESI-MS by comparing with the performance of conventional ESI-MS. The ion signals generated by SAESI-MS and APCI-MS were observed in clearly different m/z ranges. A variety of potential compounds were detected in the petroleum ether extracts of Pogostemon cablin and Ligusticum chuanxiong. The relative abundances and signal intensities of the same ion signals from the stems, leaves and decoction pieces of Pogostemon cablin were significantly different by SAESI-MS. CONCLUSIONS: As a convenient and efficient method, SAESI-MS can be used to directly detect compounds (especially the low-polarity compounds) in nonpolar or low-polarity solvent extracts of herbal medicines, providing abundant chemical information for pharmacological studies. SAESI-MS allows the simultaneous qualitative analysis of multiple compounds in the same complex samples and is thus particularly suitable for the preliminary screening of compounds in complex samples. SAESI-MS can be used to differentiate the different parts of herbal medicines. PMID- 29178527 TI - Reconstruction of elbow skin and soft tissue defects using perforator-pedicled propeller flaps. AB - BACKGROUND: The elbow is a challenging region to reconstruct functionally. Several closure methods for elbow wounds have been reported, including flap surgery. Here, we present the results obtained using a propeller flap pedicled by a posterior ulnar recurrence artery perforator (PURAP) or a radial collateral artery perforator (RCAP) for functional reconstruction of soft tissue defects in elbows. METHODS: Twenty-four patients with an average age of 27.0 years (range, 9 52 years) underwent elbow soft tissue reconstructions between 2005 and 2015. Twenty-one patients were male and three were female. Among them, 18 patients received a PURAP flap transfer and six received a RCAP flap transfer. The frequent soft tissue defects were due to release of a postburn scar contracture in 12 patients, trauma in ten patients. Functional results were obtained by measuring range of motion (ROM). RESULTS: The mean follow up time was 10.1 months (range, 4-22 months). The flaps ranged in size from 3 * 5 cm to 16 * 6 cm. Nearly all flaps survived with only one showing partial necrosis. 16 and 8 patients achieved ranges of motions of 0-5 and 6-15 degree extension and 130-145 degree flexion. CONCLUSIONS: With the aims of easy flap harvest, primary donor site closure, skin texture match, and avoiding vascular anastomosis, both PURAP and RCAP were employed. Both flap transfer techniques were safe and effective for elbow soft tissue reconstruction. It is important to ensure that the skin defect and flap design are closely matched. PMID- 29178528 TI - Nanoscale Chemical Imaging of Reversible Photoisomerization of an Azobenzene Thiol Self-Assembled Monolayer by Tip-Enhanced Raman Spectroscopy. AB - An understanding of the photoisomerization mechanism of molecules bound to a metal surface at the molecular scale is required for designing photoswitches at surfaces. It has remained a challenge to correlate the surface structure and isomerization of photoswitches at ambient conditions. Herein, the photoisomerization of a self-assembled monolayer of azobenzene-thiol molecules on a Au surface was investigated using scanning tunneling microscopy and tip enhanced Raman spectroscopy. The unique signature of the cis isomer at 1525 cm-1 observed in tip-enhanced Raman spectra was clearly distinct from the trans isomer. Furthermore, tip-enhanced Raman images of azobenzene thiols after ultraviolet and blue light irradiation are shown with nanoscale spatial resolution, demonstrating a reversible conformational change. Interestingly, the cis isomers of azobenzene-thiol molecules were preferentially observed at Au grain edges, which is confirmed by density functional theory. PMID- 29178529 TI - Evidence-based (S3) guideline for the treatment of androgenetic alopecia in women and in men - short version. AB - Androgenetic alopecia is the most common hair loss disorder, affecting both men and women. Initial signs of androgenetic alopecia usually develop during teenage years leading to progressive hair loss with a pattern distribution. Moreover, its frequency increases with age and affects up to 80% Caucasian men and 42% of women. Patients afflicted with androgenetic alopecia may undergo significant impairment of quality of life. The European Dermatology Forum (EDF) initiated a project to develop evidence-based guidelines for the treatment of androgenetic alopecia. Based on a systematic literature research the efficacy of the currently available therapeutic options was assessed and therapeutic recommendations were passed in a consensus conference. The purpose of the guideline is to provide dermatologists with an evidence-based tool for choosing an efficacious and safe therapy for patients with androgenetic alopecia. PMID- 29178530 TI - Photoluminescent properties of Eu3+ -Eu2+ activated MAl2 Six O2x + 4 (M = Mg, Ca, Sr, Ba) phosphors prepared in air. AB - In this paper, MAl2 Six O2x+4 :Eu2+ /Eu3+ (Eu2+ + Eu3+ = 2%, molar ratio; M = Mg, Ca, Sr, Ba; x = 0, 0.5, 1, 1.5, 2) phosphors with different SiO2 concentrations (the ratio of SiO2 to MAl2 O4 is n%, n = 0, 50, 100, 150, 200, respectively) were prepared by high-temperature solid-state reaction under atmospheric air conditions. Their structures and photoluminescent properties were systematically researched. The results indicate that Eu3+ ions have been reduced and Eu2+ ions are obtained in air through the self-reduction mechanism. The alkaline earth metal ions and doping SiO2 strongly affect the crystalline phase and photoluminescent properties of samples, including microstructures, relative intensity of Eu2+ to Eu3+ , location of emission lines/bands. It is interesting and important that the emission color and intensities of europium-doped various phosphors which consist of aluminosilicate matrices prepared under atmospheric air conditions could be modulated by changing the kinds of alkaline earth metal and the content of SiO2 . PMID- 29178531 TI - Vertical vs. horizontal transmission of the microbiome in a key disease vector, Ixodes pacificus. AB - Vector-borne pathogens are increasingly found to interact with the vector's microbiome, influencing disease transmission dynamics. However, the processes that regulate the formation and development of the microbiome are largely unexplored for most tick species, an emerging group of disease vectors. It is not known how much of the tick microbiome is acquired through vertical transmission vs. horizontally from the environment or interactions with bloodmeal sources. Using 16S rRNA sequencing, we examined the microbiome of Ixodes pacificus, the vector of Lyme disease in the western USA, across life stages and infection status. We also characterized microbiome diversity in field and laboratory collected nymphal ticks to determine how the surrounding environment affects microbiome diversity. We found a decrease in both species richness and evenness as the tick matures from larva to adult. When the dominant Rickettsial endosymbiont was computationally removed from the tick microbial community, we found that infected nymphs had lower species evenness than uninfected ticks, suggesting that lower microbiome diversity is associated with pathogen transmission in wild-type ticks. Furthermore, laboratory-reared nymph microbiome diversity was found to be compositionally distinct and significantly depauperate relative to field-collected nymphs. These results highlight unique patterns in the microbial community of I. pacificus that is distinct from other tick species. We provide strong evidence that ticks acquire a significant portion of their microbiome through exposure to their environment despite a loss of overall diversity through life stages. We provide evidence that loss of microbial diversity is at least in part due to elimination of microbial diversity with bloodmeal feeding but other factors may also play a role. PMID- 29178532 TI - Microfluidics Based Point-of-Care Diagnostics. AB - Point-of-care (POC) diagnostic devices have been predicted to provide a boon in health care especially in the diagnosis and detection of diseases. POC devices have been found to have many advantages like a rapid and precise response, portability, low cost, and non-requirement of specialized equipment. The major objective of a POC diagnostic research is to develop a chip-based, self containing miniaturized device that can be used to examine different analytes in complex samples. Further, the integration of microfluidics (MF) with advanced biosensor technologies is likely to result in improved POC diagnostics. This paper presents the overview of the different materials (glass, silicon, polymer, paper) and techniques for the fabrication of MF based POC devices along with their wide range of biosensor applications. Besides this, the authors have presented in brief the challenges that MF is currently facing along with possible solutions that may result in the availability of the accessible, reliable, and cost-efficient technology. The development of these devices requires the combination of developed MF components into POC devices that are user-friendly, sensitive, stable, accurate, low cost, and minimally invasive. These MF based POC devices have tremendous potential in providing improved healthcare including easy monitoring, early detection of disease, and increased personalization. PMID- 29178533 TI - Urethral Complications After Transgender Phalloplasty: Strategies to Treat Them and Minimize Their Occurrence. AB - Radial forearm free flap phalloplasty (RFFP) is the current standard of care for most FTM gender confirmation surgeries. This procedure is associated with a rate of urethral stricture as high as 51%, which falls only to 23-35% even among the most experienced contemporary surgeons. While some modifications have been proposed to combat this high complication rate, it still remains a major source of lasting morbidity. The method involves literature review of RFFP literature. Lowest stricture rates are found when neourethra is made with a long, meticulously constructed tube of well-vascularized perivaginal/periurethral and labia minora tissue. In cases of urethral stricture, urethroplasty is required in 94-96% of patients. Surgery should be delayed until all acute inflammation has subsided. Urethroplasty is technically challenging and fails in up to 50% of cases. Repeated surgery or salvage urethral exteriorization procedures, which can leave the patient with lifelong perineal urethrostomy, are often required. Patient and physician knowledge regarding the high burden and poor treatment options for urethral stricture after phalloplasty is incomplete, and patient acceptance of this reality is crucial for honest understanding of the potential complications of this increasingly common but extremely complex surgery.

PMID- 29178535 TI - Peritraumatic Assessment of Autobiographical Memory After Exposure to a Traumatic Event. AB - Posttraumatic stress disorder (PTSD) is commonly acknowledged to be associated with reduced specificity of autobiographical memory (AM). However, very few studies have assessed AM in the peritraumatic phase. The aim of the present study was to examine whether the AM impairment reported in PTSD is present a few days after a traumatic event. We assessed AM in 41 participants who had recently been exposed to trauma, and 34 controls who had never experienced a traumatic situation. The trauma-exposed participants also completed the Impact of Event Scale-R (IES-R), the Inventory of Peritraumatic Distress, and the Peritraumatic Dissociative Experiences Questionnaire. Results showed that autobiographical memories cued by negative words were significantly less specific in the group of trauma-exposed participants than in the control group (p = .008; d = 0.40). Thus, mild AM impairment was already present three days after trauma exposure, long before acute PTSD set in. PMID- 29178536 TI - Effects of an energy-restricted low-carbohydrate, high unsaturated fat/low saturated fat diet versus a high-carbohydrate, low-fat diet in type 2 diabetes: A 2-year randomized clinical trial. AB - AIM: To examine whether a low-carbohydrate, high-unsaturated/low-saturated fat diet (LC) improves glycaemic control and cardiovascular disease (CVD) risk factors in overweight and obese patients with type 2 diabetes (T2D). METHODS: A total of 115 adults with T2D (mean [SD]; BMI, 34.6 [4.3] kg/m2 ; age, 58 [7] years; HbA1c, 7.3 [1.1]%) were randomized to 1 of 2 planned energy-matched, hypocaloric diets combined with aerobic/resistance exercise (1 hour, 3 days/week) for 2 years: LC: 14% energy as carbohydrate, 28% as protein, 58% as fat (<10% saturated fat); or low-fat, high-carbohydrate, low-glycaemic index diet (HC): 53% as CHO, 17% as protein, 30% as fat (<10% saturated fat). HbA1c, glycaemic variability (GV), anti-glycaemic medication effect score (MES, calculated based on the potency and dosage of diabetes medication), weight, body composition, CVD and renal risk markers were assessed before and after intervention. RESULTS: A total of 61 (LC = 33, HC = 28) participants completed the study (trial registration: http://www.anzctr.org.au/, ANZCTR No. ACTRN12612000369820). Reductions in weight (estimated marginal mean [95% CI]; LC, -6.8 [-8.8,-4.7], HC, -6.6 [-8.8, -4.5] kg), body fat (LC, -4.3 [-6.2, -2.4], HC, -4.6 [-6.6, -2.7] kg), blood pressure (LC, -2.0 [-5.9, 1.8]/ -1.2 [-3.6, 1.2], HC, -3.2 [-7.3, 0.9]/ -2.0 [-4.5, 0.5] mmHg), HbA1c (LC, -0.6 [-0.9, -0.3], HC, -0.9 [-1.2, -0.5] %) and fasting glucose (LC, 0.3 [-0.4, 1.0], HC, -0.4 [-1.1, 0.4] mmol/L) were similar between groups (P >= 0.09). Compared to HC, the LC achieved greater reductions in diabetes medication use (MES; LC, -0.5 [-0.6, -0.3], HC, -0.2 [ 0.4, -0.02] units; P = 0.03), GV (Continuous Overall Net Glycemic Action calculated every 1 hour (LC, -0.4 [-0.6, -0.3], HC, -0.1 [-0.1, 0.2] mmol/L; P = 0.001), and 4 hours (LC, -0.9 [-1.3, -0.6], HC, -0.2 [-0.6, 0.1] mmol/L; P = 0.02)); triglycerides (LC, -0.1 [-0.3, 0.2], HC, 0.1 [-0.2, 0.3] mmol/L; P = 0.001), and maintained HDL-C levels (LC, 0.02 [-0.05, 0.1], HC, -0.1 [-0.1, 0.01] mmol/L; P = 0.004), but had similar changes in LDL-C (LC, 0.2 [-0.1, 0.5], HC, 0.1 [-0.2, 0.4] mmol/L; P = 0.85), brachial artery flow mediated dilatation (LC, 0.5 [-1.5, 0.5], HC, -0.4 [-1.4, 0.7] %; P = 0.73), eGFR and albuminuria. CONCLUSIONS: Both diets achieved comparable weight loss and HbA1c reductions. The LC sustained greater reductions in diabetes medication requirements, and in improvements in diurnal blood glucose stability and blood lipid profile, with no adverse renal effects, suggesting greater optimization of T2D management. PMID- 29178538 TI - Evidence for Itinerant Carriers in an Anisotropic Narrow-Gap Semiconductor by Angle-Resolved Photoemission Spectroscopy. AB - The ability to accurately determine the electronic structure of solids has become a key prerequisite for modern functional materials. For example, the precise determination of the electronic structure helps to balance the three thermoelectric parameters, which is the biggest challenge to design high performance thermoelectric materials. Herein, by high-resolution, angle-resolved photoemission spectroscopy (ARPES), the itinerant carriers in CsBi4 Te6 (CBT) are revealed for the first time. CBT is a typical anisotropic, narrow-gap semiconductor used as a practical candidate for low-temperature thermoelectric applications, and p-doped CBT series show superconductivity at relatively low carrier concentrations. The ARPES results show a significantly larger bandwidth near the Fermi surface than calculations, which means the carriers transport anisotropically and itinerantly in CBT. It is reasonable to believe that these newly discovered features of carriers in narrow-gap semiconductors are promising for designing optimal thermoelectric materials and superconductors.

AB - Sheep breeding has suffered economic losses due to parasitism by gastrointestinal nematodes, particularly Haemonchus contortus. The use of natural products, specifically Tagetes patula, has been suggested as an alternative method of combatting this issue. Chemical analyses of the extracts of this species described in the literature report the presence of important classes of secondary metabolites such as thiophenes, flavonoids, alkaloids, and benzofurans, some of which were identified and isolated in this study. The aim of this work was to test the effect of the essential oil (EO) and the ethanolic extract of the aerial parts (TpEtOH ) of T. patula on eggs and larvae of H. contortus, through an egg hatch test (EHT) and a larval development test (LDT). In the EHT, the EO showed 100% inhibition at 0.75 mg mL-1 (LC50 = 0.0780 mg mL-1 ), and the TpEtOH showed 100% inhibition at 100 mg mL-1 (LC50 = 12.8 mg mL-1 ). In the LDT, the EO showed 100% inhibition at 0.375 mg mL-1 (LC50 = 0.0400 mg mL-1 ), and the TpEtOH showed 100% inhibition at 1.56 mg mL-1 (LC50 = 0.340 mg mL-1 ). Compared to available literature data, the results presented here suggest that the crude extracts of T. patula have substantial potential for controlling this nematode by interrupting its life cycle and/or preventing it from reaching the infective stage. PMID- 29178539 TI - Non-melanoma Hutchinson's sign: a reappraisal of this important, remarkable melanoma simulant. AB - BACKGROUND: More than 20 years ago, our reappraisal of the Hutchinson's sign (HS) gave birth to the concept of the pseudo-Hutchinson's sign. OBJECTIVES: We have found it interesting to emphasize some important histologic points and to expand the list of the numerous HS simulants. METHODS: We have examined the cutaneous samples taken from the pigmented skin of patients in association with nail matrix biopsy. We have also extended the long list of non-melanoma HS based on comprehensive literature review. RESULTS: Histologically, HS may present only as an epidermal pigmentation, depending on the area sampled. Occasionally, there may be a sparse junctional melanocytic proliferation which does not demonstrate cytologic atypia due to an underlying melanocytic naevus of the nail matrix. However, early HS often shows a melanoma in situ, with a HS at the proximal nail fold (PNF) and confluent "atypical" melanocytes in the nail matrix. Finally, involvement of the PNF, nail matrix and nail bed containing atypical melanocytes in irregular array may be seen in more advanced lesions. The recent literature on non-melanoma HS simulants is summarized and clinical examples are provided. CONCLUSION: The mere presence of periungual pigmentation is neither clinically nor histologically pathognomonic of subungual melanoma and justifies the usefulness of this work stressing the non-melanoma HS. PMID- 29178540 TI - Can time to failure predict the faulty component in artificial urinary sphincter device malfunctions? AB - OBJECTIVE: Artificial urinary sphincter malfunctions can occur in any of the individual components. Preoperative identification of the malfunctioning component can be valuable for patient counseling and surgical planning. The optimal strategy for repair of failed artificial urinary sphincter components is debated given the relative rarity of the situation. The aim of the present study was to evaluate the relationship of time to failure with failed artificial urinary sphincter component and to compare our outcomes of specific component versus complete device replacement. METHODS: From 1983 to 2011, 1805 artificial urinary sphincter procedures were carried out at Mayo Clinic (Rochester, Minnesota, USA), of which 1072 patients underwent primary artificial urinary sphincter placement. Clinical variables, including time to failure, were evaluated for association with component failure. Bootstrap analysis was used to estimate the differences in time to reach a fixed percentage of component failure. RESULTS: A total of 115 patients experienced device failure at a median follow up of 4.2 years. Urethral cuff, abdominal reservoir, scrotal pump and tubing malfunction occurred in 53 (4.9%), 26 (2.4%), 11 (1%) and 25 (2.3%) patients, respectively. Increasing age at the time of primary surgery was protective of cuff malfunction (hazard ratio 0.97, P = 0.04). Time to 3% urethral cuff failure outpaced other component failures (P < 0.05). Secondary failure-free rates after whole device versus specific component revisions were comparable (P = 0.38). CONCLUSIONS: Clinical predictors for artificial urinary sphincter failure continue to be difficult to establish. Although single component versus entire device replacement have similar outcomes, if pursuing single component revision, we recommend cuff-first interrogation in devices in place for >3 years, as this represents the most likely component to fail. PMID- 29178541 TI - Violence against emergency medical services personnel: A systematic review of the literature. AB - BACKGROUND: Violence against emergency medical services (EMS) personnel is a growing concern. The aim of this systematic review is to synthesize the current literature on violence against EMS personnel. METHODS: We examined literature from 2000 to 2016. Eligibility criteria included English-language, peer-reviewed studies of EMS personnel that described violence or assaults. Sixteen searches identified 2655 studies; 25 studies from nine countries met the inclusion criteria. RESULTS: The evidence from this review demonstrates that violence is a common risk for EMS personnel. We identified three critical topic areas: changes in risk over time, economic impact of violence and, outcomes of risk-reduction interventions. There is a lack of peer reviewed research of interventions, with the result that current intervention programs have no reliable evidence base. CONCLUSIONS: EMS leaders and personnel should work together with researchers to design, implement, evaluate and publish intervention studies designed to mitigate risks of violence to EMS personnel. PMID- 29178542 TI - E-selectin gene in essential hypertension: a case-control study. AB - BACKGROUND: Hypertension is associated with endothelial cell dysfunction. E selectin, an endothelial cell adhesion molecule, is specific for endothelial cell activation. Polymorphism in E-selectin gene has recently been identified among which Leu554Phe E-selectin gene polymorphism is least investigated in essential hypertension. This study reports the association of E-selectin gene Leu554Phe polymorphism and the expression of E-selectin gene in patients with essential hypertension. MATERIALS AND METHODS: We analysed the Leu554Phe polymorphism and expression of E-selectin gene in 250 patients with essential hypertension and 250 normal healthy controls. Genotyping of Leu554Phe polymorphism was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and the expression of E-selectin gene at mRNA and protein levels were carried out by real-time PCR and Western blot, respectively. RESULTS: A significant association of E-selectin genotypes (CT + TT) with essential hypertension (P < .0001, Odds ratio = 2.2 [1.58-3.24] at 95% CI) was observed. The expression of mRNA for E-selectin gene in patients with essential hypertension was ~12-fold higher as compared to control. We observed an elevated level of E-selectin protein expression (up to 1.9 times) in patients as compared to controls. CONCLUSIONS: A significant association of E-selectin (Leu554Phe) gene and increased expression of E-selectin gene at mRNA and protein levels in patients might be related to the genetic predisposition to develop essential hypertension. PMID- 29178543 TI - Neovaginal Construction with Pelvic Peritoneum: Reviewing an Old Approach for a New Application. AB - Transgender reassignment surgeries have become a major topic of interest within the last decade. Although there are numerous surgical techniques for male-to female reassignment, a physician must assess each patient's anatomy and past medical history to determine the most suitable technique. Additionally, patient preference is important. The neovaginal constructive technique most commonly used in male-to-female reassignment surgery is penile skin inversion, but various other techniques and tissues can also be used including pelvic peritoneum, buccal mucosa, and bowel. Surgical text descriptions were enhanced by creating new anatomical illustrations. Donor and recipient site anatomies, and the surgical technique leading to creation of the neovagina, are demonstrated in detail with relevant illustrations. A review of the literature concerning the anatomy, procedure development, and outcomes is presented. The pelvic peritoneum was originally used in neovaginal construction for females with vaginal agenesis as a result of MRKH syndrome. The use of this technique to create a neovagina in male to-female transgender reassignment surgery has become appealing owing to the relative ease of the procedure, low complication rates, and overall high patient satisfaction. This technique offers a potential new choice for transgender male to-female neovaginal construction, but further studies are needed to confirm its successful use in transgender surgery. Clin.

AB - The aim of this study was to provide a systematic overview of available pressure ulcer prevention quality indicators and to evaluate the underlying empirical evidence. A systematic mapping review was conducted with combined searches in Embase and Medline, and websites of relevant institutions and organisations. The eligibility criteria were clear use of the term "quality indicator" regarding pressure ulcer prevention; English or German language; and all settings, populations, and types of resources, including articles, brochures, and online material. In total, n = 146 quality indicators were identified. Most indicators were published in the United States (n = 50). The majority of indicators was developed for the hospital setting (n = 102). Process indicators were the most common (n = 71), followed by outcome indicators (n = 49). Less than half of identified indicators appeared to be practically used. Evidence supporting the validity and reliability were reported for n = 25 and n = 30 indicators respectively. The high number of indicators demonstrate the importance of measuring pressure ulcer prevention quality. This is not an indicator of our ability to accurately measure and evaluate this construct. There is an urgent need to develop evidence-based and internationally comparable indicators to help improve patient care and safety worldwide. PMID- 29178546 TI - Evaluation of dosimetric advantages of using patient-specific aperture system with intensity-modulated proton therapy for the shallow depth tumor. AB - In this study, we evaluate dosimetric advantages of using patient-specific aperture system with intensity-modulated proton therapy (IMPT) for head and neck tumors at the shallow depth. We used four types of patient-specific aperture system (PSAS) to irradiate shallow regions less than 4 g/cm2 with a sharp lateral penumbra. Ten head and neck IMPT plans with or without aperture were optimized separately with the same 95% prescription dose and same dose constraint for organs at risk (OARs). The plans were compared using dose volume histograms (DVHs), dose distributions, and some dose indexes such as volume receiving 50% of the prescribed dose (V50 ), mean or maximum dose (Dmean and Dmax ) to the OARs. All examples verified in this study had decreased V50 and OAR doses. Average, maximum, and minimum relative reductions of V50 were 15.4%, 38.9%, and 1.0%, respectively. Dmax and Dmean of OARs were decreased by 0.3% to 25.7% and by 1.0% to 46.3%, respectively. The plans with the aperture over more than half of the field showed decreased V50 or OAR dose by more than 10%. The dosimetric advantage of patient-specific apertures with IMPT was clarified in many cases. The PSAS has some dosimetric advantages for clinical use, and in some cases, it enables to fulfill dose constraints. PMID- 29178547 TI - Safe-by-Design Ligand-Coated ZnO Nanocrystals Engineered by an Organometallic Approach: Unique Physicochemical Properties and Low Toxicity toward Lung Cells. AB - The unique physicochemical properties and biocompatibility of zinc oxide nanocrystals (ZnO NCs) are strongly dependent on the nanocrystal/ligand interface, which is largely determined by synthetic procedures. Stable ZnO NCs coated with a densely packed shell of 2-(2-methoxyethoxy)acetate ligands, which act as miniPEG prototypes, with average core size and hydrodynamic diameter of 4 5 and about 12 nm, respectively, were prepared by an organometallic self supporting approach, fully characterized, and used as a model system for biological studies. The ZnO NCs from the one-pot, self-supporting organometallic procedure exhibit unique physicochemical properties such as relatively high quantum yield (up to 28 %), ultralong photoluminescence decay (up to 2.1 MUs), and EPR silence under standard conditions. The cytotoxicity of the resulting ZnO NCs toward normal (MRC-5) and cancer (A549) human lung cell lines was tested by MTT assay, which demonstrated that these brightly luminescent, quantum-sized ZnO NCs have a low negative impact on mammalian cell lines. These results substantiate that the self-supporting organometallic approach is a highly promising method to obtain high-quality, nontoxic, ligand-coated ZnO NCs with prospective biomedical applications. PMID- 29178545 TI - Genome-Wide Study of Subcutaneous and Visceral Adipose Tissue Reveals Novel Sex Specific Adiposity Loci in Mexican Americans. AB - OBJECTIVE: This study aimed to explore the genetic mechanisms of regional fat deposition, which is a strong risk factor for metabolic diseases beyond total adiposity. METHODS: A genome-wide association study of 7,757,139 single nucleotide polymorphisms (SNPs) in 983 Mexican Americans (nmale = 403; nfemale = 580) from the Insulin Resistance Atherosclerosis Family Study was performed. Association analyses were performed with and without sex stratification for subcutaneous adipose tissue, visceral adipose tissue (VAT), and visceral subcutaneous ratio (VSR) obtained from computed tomography. RESULTS: The strongest signal identified was SNP rs2185405 (minor allele frequencies [MAF] = 40%; PVAT = 1.98 * 10-8 ) with VAT. It is an intronic variant of the GLIS family zinc finger 3 gene (GLIS3). In addition, SNP rs12657394 (MAF = 19%) was associated with VAT in males (Pmale = 2.39*10-8 ; Pfemale = 2.5 * 10-3 ). It is located intronically in the serum response factor binding protein 1 gene (SRFBP1). On average, male carriers of the variant had 24.6 cm2 increased VAT compared with noncarriers. Subsequently, genome-wide SNP-sex interaction analysis was performed. SNP rs10913233 (MAF = 14%; Pint = 3.07 * 10-8 ) in PAPPA2 and rs10923724 (MAF = 38%; Pint = 2.89 * 10-8 ) upstream of TBX15 were strongly associated with the interaction effect for VSR. CONCLUSIONS: Six loci were identified with genome-wide significant associations with fat deposition and interactive effects. These results provided genetic evidence for a differential basis of fat deposition between genders. PMID- 29178548 TI - Preservation of neuronal functions by exosomes derived from different human neural cell types under ischemic conditions. AB - Stem cell-based therapies have been reported in protecting cerebral infarction induced neuronal dysfunction and death. However, most studies used rat/mouse neuron as model cell when treated with stem cell or exosomes. Whether these findings can be translated from rodent to humans has been in doubt. Here, we used human embryonic stem cell-derived neurons to detect the protective potential of exosomes against ischemia. Neurons were treated with in vitro oxygen-glucose deprivation (OGD) for 1 h. For treatment group, different exosomes were derived from neuron, embryonic stem cell, neural progenitor cell and astrocyte differentiated from H9 human embryonic stem cell and added to culture medium 30 min after OGD (100 MUg/mL). Western blotting was performed 12 h after OGD, while cell counting and electrophysiological recording were performed 48 h after OGD. We found that these exosomes attenuated OGD-induced neuronal death, Mammalian target of rapamycin (mTOR), pro-inflammatory and apoptotic signaling pathway changes, as well as basal spontaneous synaptic transmission inhibition in varying degrees. The results implicate the protective effect of exosomes on OGD-induced neuronal death and dysfunction in human embryonic stem cell-derived neurons, potentially through their modulation on mTOR, pro-inflammatory and apoptotic signaling pathways. PMID- 29178550 TI - Ultrathin 2D Photocatalysts: Electronic-Structure Tailoring, Hybridization, and Applications. AB - As a sustainable technology, semiconductor photocatalysis has attracted considerable interest in the past several decades owing to the potential to relieve or resolve energy and environmental-pollution issues. By virtue of their unique structural and electronic properties, emerging ultrathin 2D materials with appropriate band structure show enormous potential to achieve efficient photocatalytic performance. Here, the state-of-the-art progress on ultrathin 2D photocatalysts is reviewed and a critical appraisal of the classification, controllable synthesis, and formation mechanism of ultrathin 2D photocatalysts is presented. Then, different strategies to tailor the electronic structure of ultrathin 2D photocatalysts are summarized, including component tuning, thickness tuning, doping, and defect engineering. Hybridization with the introduction of a foreign component and maintaining the ultrathin 2D structure is presented to further boost the photocatalytic performance, such as quantum dots/2D materials, single atoms/2D materials, molecular/2D materials, and 2D-2D stacking materials. More importantly, the advancement of versatile photocatalytic applications of ultrathin 2D photocatalysts in the fields of water oxidation, hydrogen evolution, CO2 reduction, nitrogen fixation, organic syntheses, and removal pollutants is discussed. Finally, the future opportunities and challenges regarding ultrathin 2D photocatalysts to bring about new opportunities for future research in the field of photocatalysis are also presented. PMID- 29178549 TI - Evaluation of AAPM Reports 204 and 220: Estimation of effective diameter, water equivalent diameter, and ellipticity ratios for chest, abdomen, pelvis, and head CT scans. AB - PURPOSE: To confirm AAPM Reports 204/220 and provide data for the future expansion of these reports by: (a) presenting the first large-scale confirmation of the reports using clinical data, (b) providing the community with size surrogate data for the head region which was not provided in the original reports, and additionally providing the measurements of patient ellipticity ratio for different body regions. METHOD: A total of 884 routine scans were included in our analysis including data from the head, thorax, abdomen, and pelvis for adults and pediatrics. We calculated the ellipticity ratio and all of the size surrogates presented in AAPM Reports 204/220. We correlated the purely geometric based metrics with the "gold standard" water-equivalent diameter (DW ). RESULTS: Our results and AAPM Reports 204/220 agree within our data's 95% confidence intervals. Outliers to the AAPM reports' methods were caused by excess gas in the GI tract, exceptionally low BMI, and cranial metaphyseal dysplasia. For the head, we show lower correlation (R2 = 0.812) between effective diameter and DW relative to other body regions. The ellipticity ratio of the shoulder region was the highest at 2.28 +/- 0.22 and the head the smallest at 0.85 +/- 0.08. The abdomen pelvis, chest, thorax, and abdomen regions all had ellipticity values near 1.5. CONCLUSION: We confirmed AAPM reports 204/220 using clinical data and identified patient conditions causing discrepancies. We presented new size surrogate data for the head region and for the first time presented ellipticity data for all regions. Future automatic exposure control characterization should include ellipticity information. PMID- 29178551 TI - Solubilization and Upgrading of High Polyethylene Terephthalate Loadings in a Low Costing Bifunctional Ionic Liquid. AB - The solubilization and efficient upgrading of high loadings of polyethylene terephthalate (PET) are important challenges, and most solvents for PET are highly toxic. Herein, a low-cost (ca. $1.2 kg-1 ) and biocompatible ionic liquid (IL), cholinium phosphate ([Ch]3 [PO4 ]), is demonstrated for the first time to play bifunctional roles in the solubilization and glycolytic degradation of PET. A high loading of PET (10 wt %) was readily dissolved in [Ch]3 [PO4 ] at relatively low temperatures (120 degrees C, 3 h) and under water-rich conditions. In-depth analysis of the solution revealed that high PET solubilization in [Ch]3 [PO4 ] could be ascribed to significant PET depolymerization. Acid precipitation yielded terephthalic acid as the dominant depolymerized monomer with a theoretical yield of approximately 95 %. Further exploration showed that in the presence of ethylene glycol (EG), the [Ch]3 [PO4 ] catalyzed glycolysis of PET could efficiently occur with approximately 100 % conversion of PET and approximately 60.6 % yield of bis(2 hydroxyethyl)terephthalate under metal-free conditions. The IL could be reused at least three times without an apparent decrease in activity. NMR spectroscopy analysis revealed that strong hydrogen-bonding interactions between EG and the IL played an important role in the activation of EG and promotion of the glycolysis reaction. This study opens up avenues for exploring environmentally benign and efficient IL technology for solubilizing and recycling postconsumer polyester plastics. PMID- 29178552 TI - Educational and practice gaps in the management of volar melanocytic lesions. AB - BACKGROUND: The benign and malignant patterns of acral melanocytic naevi (AMN) and acral melanomas (AM) have been defined in a series of retrospective studies. A three-step algorithm was developed to determine when to biopsy acral melanocytic lesions. This algorithm has only been applied to a Japanese population. OBJECTIVES: Our study aimed to review the current management strategy of acral melanocytic lesions and to investigate the utility of the three-step algorithm in a predominately Caucasian cohort. METHODS: A retrospective search of the pathology and image databases at Mayo Clinic was performed between the years 2006 and 2016. Only cases located on a volar surface with dermoscopic images were included. Two dermatologists reviewed all dermoscopic images and assigned a global dermoscopic pattern. Clinical and follow-up data were gathered by chart review. All lesions with known diameter and pathological diagnosis were used for the three-step algorithm. RESULTS: Regular fibrillar and ridge patterns were more likely to be biopsied (P = 0.01). The majority of AMN (58.1%) and AM (60%) biopsied were due to physician-deemed concerning dermoscopic patterns. 39.2% of these cases were parallel furrow, lattice-like or regular fibrillar. When patients were asked to follow-up within a 3- to 6-month period, only 16.7% of the patients returned within that interval. The three-step algorithm would have correctly identified four of five AM for biopsy, missing a 6 mm, multicomponent, invasive melanoma. CONCLUSION: We found one major educational gap in the recognition of low-risk lesions with high rates of biopsy of the fibrillary pattern. Recognizing low-risk dermoscopic patterns could reduce the rate of biopsy of AMN by 23.3%. We identified two major practice gaps, poor patient compliance with follow-up and the potential insensitivity of the three-step algorithm to small multicomponent acral melanocytic lesions. PMID- 29178553 TI - Advancing alcohol research and treatment: contentions and debates about treatment intensity, goals and outcomes in the 1970s and 1980s. AB - AIMS: This narrative exploration of alcohol treatment research focuses on key contentions and advances in alcohol treatment during the critical 1970s and 1980s. METHODS: Papers and books which signal some of the major debates and advances in alcohol treatment research were selected from the 1970s and 1980s. The selection process was based on significant debate during this period, and included those that influenced the field in general and this author in particular. RESULTS: This was a period where challenges to traditional models and concepts, and the perceived universal need for long-term treatment, were accompanied by contention but also advances in research and treatment approaches. The debates and advances resonate today. These include the recognition that: intensive and long-term treatment is not always required; for dependent drinkers, relapse is a common treatment outcome meriting specific treatment approaches to prevent and reduce this risk; controlled drinking is a treatment option, especially for younger and less dependent drinkers; and an important contributor to enduring change is access to, and realization of, improvements in the quality of life. CONCLUSIONS: Pioneering research and publications in the 1970s and 1980s, sometimes conducted and produced in contentious contexts, influenced significantly conceptualizations of alcohol-related problems, and laid the foundations for treatment hypotheses and research, improving access to a broader range of evidence-based treatment. These underpinning works influenced the development of stepped-up care from brief to intensive interventions, relapse prevention and treatment options not limited to abstinence, and they identified the need to include a stronger focus on quality of life. PMID- 29178555 TI - Ideal Dimers of Gold Nanospheres for Precision Plasmonics: Synthesis and Characterization at the Single-Particle Level for Identification of Higher Order Modes. AB - Ideal dimers comprising gold nanoparticles with a smooth surface and high sphericity are synthesized by a substrate-based assembly strategy with efficient cetyltrimethylammonium bromide removal. An unprecedented structural and plasmonic uniformity at the single-particle level is observed since inhomogeneities resulting from variations in gap morphology are eliminated. Single ideal dimers are analyzed by polarization-resolved dark-field scattering spectroscopy. Contributions from transverse as well as quadrupolar and octupolar longitudinal plasmon coupling modes can be discriminated because of their orthogonal polarization behavior. The assignment of these higher order coupling modes is supported by computer simulations. PMID- 29178554 TI - Selective T-cell depletion targeting CD45RA reduces viremia and enhances early T cell recovery compared with CD3-targeted T-cell depletion. AB - BACKGROUND: T-cell depletion (TCD) effectively reduces severe graft-versus-host disease in recipients of HLA-mismatched allografts. However, TCD is associated with delayed immune recovery and increased infections. We hypothesized that specific depletion of CD45RA+ naive T cells, rather than broad depletion of CD3+ T cells, can preserve memory-immunity in the allografts and confer protection against important viral infections in the early post-transplant period. METHODS: Sixty-seven patients who received TCD haploidentical donor transplantation for hematologic malignancy on 3 consecutive trials were analyzed. RESULTS: Patients receiving CD45RA-depleted donor grafts had 2000-fold more donor T cells infused, significantly higher T-cell counts at Day +30 post transplant (550/MUL vs 10/MUL; P < .001), and higher T-cell diversity by Vbeta spectratyping at Day +100 (P < .001). Importantly, these recipients experienced a significant reduction in both the incidence (P = .002) and duration (P = .02) of any viremia (cytomegalovirus, Epstein-Barr virus, or adenovirus) in the first 6 months post transplant. Specifically, recipients of CD3-depleted grafts were more likely to experience adenovirus viremia (27% vs 4%, P = .02). CONCLUSION: CD45RA-depletion provided a large number of donor memory T cells to the recipients and was associated with enhanced early T-cell recovery and protection against viremia.

PMID- 29178557 TI - Theta synchronization over occipito-temporal cortices during visual perception of body parts. AB - Categorical clustering in the visual system is thought to have evolved as a function of intrinsic (intra-areal) and extrinsic (interareal) connectivity and experience. In the visual system, the extrastriate body area (EBA), an occipito temporal region, responds to full body and body part images under the organizational principle of their functional/semantic meaning. Although frequency specific modulations of neural activity associated with perceptive and cognitive functions are increasingly attracting the interest of neurophysiologists and cognitive neuroscientists, perceiving single body parts with different functional meaning and full body images induces time-frequency modulations over occipito temporal electrodes are yet to be described. Here, we studied this issue by measuring EEG in participants who passively observed fingers, hands, arms and faceless full body images with four control plant stimuli, each bearing hierarchical analogy with the body stimuli. We confirmed that occipito-temporal electrodes (compatible with the location of EBA) show a larger event-related potential (ERP, N190) for body-related images. Furthermore, we identified a body part-specific (i.e. selective for hands and arms) theta event-related synchronization increase under the same electrodes. This frequency modulation associated with the perception of body effectors over occipito-temporal cortices is in line with recent findings of categorical organization of neural responses to human effectors in the visual system.

AB - OBJECTIVE: To estimate whether different numbers of simulation training models affect medical students' cervical examination performance. METHODS: In a prospective study at Peking Union Medical College Hospital, Beijing, China, between August 1, 2016, and April 30, 2017, fifth-year medical students without obstetric experience were randomly assigned to the large or small number training groups. Participants in the large number group performed cervical examinations on 10 dilation models and nine effacement/consistency models; those in the small number group practiced on four dilation models and three effacement/consistency models. In the examination, both groups evaluated 10 models in the same sequence and reported findings. Participants also completed confidence surveys. Mann Whitney U test was used to compare the assessment accuracy and confidence improvement between the groups. RESULTS: There were 91 students randomized to the large (n=45) or small (n=46) number training groups. As compared with the small number group, the large number group demonstrated higher accuracy in assessing exact dilation (P=0.028), exact effacement (P=0.002), effacement within 0.5 cm (P=0.017), and consistency (P=0.045). There was no difference in assessing dilation within 1 cm or in confidence improvement between the groups. CONCLUSION: A small number of simulation training models was sufficient to improve students' accuracy and confidence in assessing cervical dilatation, although a large number was needed to improve accuracy in cervical effacement and consistency.

PMID- 29178559 TI - ARID1A, a component of SWI/SNF chromatin remodeling complexes, is required for porcine embryo development. AB - Mammalian embryos undergo dramatic epigenetic remodeling that can have a profound impact on both gene transcription and overall embryo developmental competence. Members of the SWI/SNF (Switch/Sucrose non-fermentable) family of chromatin remodeling complexes reposition nucleosomes and alter transcription factor accessibility. These large, multi-protein complexes possess an SNF2-type ATPase (either SMARCA4 or SMARCA2) as their core catalytic subunit, and are directed to specific loci by associated subunits. Little is known about the identity of specific SWI/SNF complexes that serve regulatory roles during cleavage development. ARID1A, one of the SWI/SNF complex subunits, can affect histone methylation in somatic cells; here, we determined the developmental requirements of ARID1A in porcine oocytes and embryos. We found ARID1A transcript levels were significantly reduced in 4-cell porcine embryos as compared to germinal vesicle stage oocytes, suggesting that ARID1A would be required for porcine cleavage stage development. Indeed, injecting in vitro-matured and fertilized porcine oocytes with double-stranded interfering RNAs that target ARID1A, and evaluating their phenotype after seven days, revealed that the depletion of ARID1A results in significantly fewer cells than their respective control groups (p < 0.001). PMID- 29178561 TI - Excited-State Dipole Moments and Transition Dipole Orientations of Rotamers of 1,2-, 1,3-, and 1,4-Dimethoxybenzene. AB - Rotationally resolved electronic Stark spectra of rotamers of 1,2-, 1,3-, and 1,4 dimethoxybenzene have been recorded and analyzed using evolutionary strategies. The experimentally determined dipole moments as well as the transition dipole moments are compared to the results of ab initio calculations. For the electronic ground states of the experimentally observed dimethoxybenzenes, the permanent dipole moments can be obtained from vectorial addition of the monomethoxybenzene dipole moment. However, this is not the case for the electronically excited states. This behavior can be traced back to a state mixing of the lowest electronically excited singlet states for the asymmetric rotamers. For the symmetric rotamers however, this is not valid. We discuss several possible reasons for the non-additivity of the dipole moments in the excited states of the symmetric rotamers. PMID- 29178562 TI - Macrolide use in the previous years is associated with failure to eradicate Helicobacter pylori with clarithromycin-containing regimens. AB - BACKGROUND: There is some evidence that prior use of macrolide antibiotics is a useful predictor of the likelihood of standard triple therapy failure in Helicobacter pylori eradication. In this study, we have evaluated whether previous intake of macrolides correlates with failure to eradicate H. pylori using two different first-line clarithromycin-containing regimens. MATERIALS AND METHODS: Retrospective study of 212 patients with H. pylori infection treated with one of two first-line clarithromycin-containing regimens: 108 patients treated with triple therapy for 10 days and 104 patients treated with concomitant therapy for 10 days. The intake of macrolides (clarithromycin, azithromycin, and other macrolides) prior to the eradication therapy was obtained from the electronic medical record, which contains information regarding all the medication prescribed to the patients since the year 2004. RESULTS: One hundred of 212 patients (47.2%) had received at least one treatment with macrolides during the years prior to the eradication therapy. H. pylori eradication rates were significantly lower in patients with previous use compared to patients without previous use of macrolides, both with triple therapy (60.8% vs 92.9%; P < .0001) and with concomitant therapy (85.7% vs 98.2%; P = .024). CONCLUSIONS: Previous use of macrolides correlates with a low H. pylori eradication rate with triple and concomitant clarithromycin-containing regimens. In addition, our study shows that in patients without previous use of macrolides, triple therapy achieves per-protocol eradication rates over 90%. PMID- 29178564 TI - A Pilot Study of Mesenchymal Stem Cell Therapy for Acute Liver Allograft Rejection. AB - Acute allograft rejection remains common after liver transplantation despite modern immunosuppressive agents. In addition, the long-term side effects of these regimens, including opportunistic infections, are challenging. This study evaluated the safety and clinical feasibility of umbilical cord-derived mesenchymal stem cell (UC-MSC) therapy in liver transplant patients with acute graft rejection. Twenty-seven liver allograft recipients with acute rejection were randomly assigned into the UC-MSC infusion group or the control group. Thirteen patients received one infusion of UC-MSCs (1 * 106 /kg body weight); one patient received multiple UC-MSC infusions; 13 patients were used as controls. All enrolled patients received conventional immunosuppressive agents with follow up for 12 weeks after UC-MSC infusions. No side effects occurred in treated patients. Four weeks after UC-MSC infusions, alanine aminotransferase levels had decreased markedly and remained lower throughout the 12-week follow-up period. Importantly, allograft histology was improved after administration of UC-MSCs. The percentage of regulatory T cells (Tregs) and the Treg/T helper 17 (Th17) cell ratio were significantly increased 4 weeks after infusions; in contrast, the percentage of Th17 cells showed a decreasing trend. In controls, the percentages of Tregs and Th17 cells and the Treg/Th17 ratio were statistically unchanged from the baseline measurements. Transforming growth factor beta 1 and prostaglandin E2 were increased significantly after UC-MSC infusions; by contrast, there were no significant changes in controls. Our data suggest that UC-MSC infusion for acute graft rejection following liver transplantation is feasible and may mediate a therapeutic immunosuppressive effect.

PMID- 29178565 TI - Adults with intellectual disabilities in China: comorbid psychiatric disorder and its association with health service utilisation. AB - BACKGROUND: Adults with intellectual disabilities (ID) often have multiple comorbidities. Psychiatric disorders in this population have been poorly studied in developing countries. We aimed to investigate the prevalence of psychiatric disorders in adults with ID and whether comorbid psychiatric disorders were associated with health service utilisation. METHODS: We obtained data from the Second National Sample Survey on Disability, conducted in 31 provinces of China and selected a subsample of 13 631 adults aged 18 years and above with ID. ID were defined by intelligence quotient score under 70, deficits in two or more adaptive behaviours and age of onset under 18 years. Psychiatric disorders were identified according to the International Statistical Classification of Diseases, Tenth Revision. Logistic regressions were used for data analyses. RESULTS: The prevalence of psychiatric disorders in adults with ID was 16.7%. The most prevalent type of psychiatric disorder was dementia. Older adults, females, being minorities, urban residents, being literate, low-income groups and having severe ID, were associated with elevated risk of psychiatric disorder among adults with ID. Compared with individuals without psychiatric disorders, those with comorbid psychiatric disorders were more likely to use medical service and less likely to use rehabilitation service. CONCLUSIONS: The prevalence of psychiatric disorder in adults with ID was strikingly higher than that in the general population. Health service utilisation among Chinese adults with ID remained a big challenge. There is a possibility of diagnostic overshadowing by local clinicians, which may have resulted in overdiagnosis of dementia and underdiagnosis of common mental disorders. This study informs further investigations regarding common mental disorders among people with ID and has implications for public health strategies and health policies to meet health service need for this population. PMID- 29178566 TI - Bridging the gap for future clinician-educators. AB - BACKGROUND: In contrast to the training required in the UK, opportunities for medical education training in the USA are limited. Resident-as-teacher programmes are typically insufficient to prepare trainees to be successful clinician educators, but few pursue formal education degrees. We sought to assess the need for, and feasibility of, a training pathway for subspecialty fellows in a large Department of Medicine that would prepare our trainees to become effective educators. METHODS: Quantitative and qualitative methods were used. Previous fellowship applicants and current programme directors were surveyed to determine the potential benefits of the programme. A pilot programme was conducted with fellows interested in education to determine the feasibility of the programme. Pilot participants were interviewed regarding the benefits that they gained from the pilot and the logistical challenges that they experienced. In contrast to the training required in the UK, opportunities for medical education training in the USA are limited RESULTS: Five highly ranked fellows would have scored our programmes higher if we offered this training pathway. Pilot participants and fellowship programme directors agreed that there is a compelling need for such a training pathway. A number of themes arose from the interviews that enabled us to build the framework for a strong programme. DISCUSSION: Our findings suggest that a clinician-educator training pathway that draws from multiple subspecialties has the potential to improve recruitment, provide needed career counselling and skills development to trainees, and to build a community of educators that will benefit the institution. Important insights from pilot participant interviews will inform the programme design, in order to keep trainees engaged and overcome logistical challenges. PMID- 29178567 TI - Prognostic markers in congenital diaphragmatic hernia: Left ventricular diameter and pulmonary hypertension. AB - BACKGROUND: The aim of this study was to investigate whether the outcome of congenital diaphragmatic hernia (CDH) in newborns can be predicted using left ventricular (LV) diameter and estimated pulmonary artery pressure. METHODS: Patients in the newborn unit in 2012-2016 were screened retrospectively. Echocardiographic measurements of 35 patients with isolated left lateral CDH and 27 healthy newborns were compared in the first 24 h of life. RESULTS: Mean LV end diastolic diameter (LVEDD) and end-systolic diameter (LVESD), and LV ejection fraction were significantly lower in the CDH group. Moreover, tricuspid regurgitation (TR) and pulmonary regurgitation (PR) were significantly higher than in the controls (P < 0.001). Six CDH patients died within the next 40 days after birth. Mean LVEDD and LVESD were significantly lower in the CHD patients who died compared with those who were discharged (P < 0.001, P = 0.016). Also, mean TR and PR (P < 0.001) and the frequency of pulmonary hypertension (PH; P = 0.001) were significantly higher in these patients. On receiver operating characteristic analysis of the CDH non-survivors, LVEDD < 11 mm (sensitivity, 100%; 95%CI: 87.9-100; specificity, 100%; 95%CI: 54.1-100) and TR > 3.5 m/s (sensitivity, 89.66%; 95%CI: 72.6-97.7; specificity, 100%; 95%CI: 54.1-100) were associated with poor prognosis. CONCLUSIONS: Decrease in LVEDD and presence of PH are associated with poor prognosis. Also, PH was associated with mortality in CDH patients. Thus, outcome may be predicted on careful echocardiographic evaluation of the LV diameters and pulmonary pressure. PMID- 29178568 TI - Hypoxia-induced intestinal barrier changes in balloon-assisted enteroscopy. AB - KEY POINTS: Balloon-assisted enteroscopy (BAE) is an emerging standard procedure by utilizing distensible balloons to facilitate deep endoscopy in the small and large intestine. Sporadic cases of bacteraemia were found after BAE. Balloon distension by BAE caused gut tissue hypoxia. The impact of balloon distension induced hypoxia on intestinal barriers remains unclear. Murine models of BAE by colonic balloon distension showed that short- and long-term hypoxia evoked opposite effects on epithelial tight junctions (TJs). Short-term hypoxia fortified TJ integrity, whereas long-term hypoxia caused damage to barrier function. Our data showed for the first time the molecular mechanisms and signalling pathways of epithelial barrier fortification and TJ reorganization by short-term hypoxia for the maintenance of gut homeostasis. The findings suggest avoiding prolonged balloon distension during BAE to reduce the risk of hypoxia induced gut barrier dysfunction. ABSTRACT: Balloon-assisted enteroscopy (BAE) is an emerging standard procedure that uses distensible balloons to facilitate deep endoscopy. Intestines are known to harbour an abundant microflora. Whether balloon distension causes perturbation of blood flow and gut barrier dysfunction, and elicits risk of bacterial translocation remains unknown. Our aims were to (1) conduct a prospective study to gather microbiological and molecular evidence of bacterial translocation by BAE in patients, (2) establish a murine model of colonic balloon distension to investigate tissue hypoxia and intestinal barrier, and (3) assess the effect of short- and long-term hypoxia on epithelial permeability using cell lines. Thirteen patients were enrolled for BAE procedures, and blood samples were obtained before and after BAE for paired comparison. Four of the 13 patients (30.8%) had positive bacterial DNA in blood after BAE. Post-BAE endotoxaemia was higher than the pre-BAE level. Nevertheless, no clinical symptom of sepsis or fever was reported. To mimic clinical BAE, mice were subjected to colonic balloon distension. Local tissue hypoxia was observed during balloon inflation, and reoxygenation after deflation. A trend of increased gut permeability was seen after long-term distension, whereas a significant reduction of permeability was observed by short-term distension in the proximal colon. Human colonic epithelial Caco-2 cells exposed to hypoxia for 5-20 min exhibited increased tight junctional assembly, while those exposed to longer hypoxia displayed barrier disruption. In conclusion, sporadic cases of bacteraemia were found after BAE, without septic symptoms. Short-term hypoxia by balloon distension yielded a protective effect whereas long-term hypoxia caused damage to the gut barrier. PMID- 29178570 TI - Shared additive genetic variation for alcohol dependence among subjects of African and European ancestry. AB - Alcohol dependence (AD) affects individuals from all racial/ethnic groups, and previous research suggests that there is considerable variation in AD risk between and among various ancestrally defined groups in the United States. Although the reasons for these differences are likely due in part to contributions of complex sociocultural factors, limited research has attempted to examine whether similar genetic variation plays a role across ancestral groups. Using a pooled sample of individuals of African and European ancestry (AA/EA) obtained through data shared within the Database for Genotypes and Phenotypes, we estimated the extent to which additive genetic similarity for AD between AA and EAs using common single nucleotide polymorphisms overlapped across the two populations. AD was represented as a factor score by using Diagnostic and Statistical Manual dependence criteria, and genetic data were imputed by using the 1000 Genomes Reference Panel. Analyses revealed a significant single nucleotide polymorphism-based heritability of 17 percent (SE = 5) in EAs and 24 percent (SE = 15) in AAs. Further, a significant genetic correlation of 0.77 (SE = 0.46) suggests that the allelic architecture influencing the AD factor for EAs and AAs is largely similar across the two populations. Analyses indicated that investigating the genetic underpinnings of alcohol dependence in different ethnic groups may serve to highlight core etiological factors common to both groups and unique etiological factors specific to each ethnic group.

PMID- 29178569 TI - A Prospective Study of Obesity, Metabolic Health, and Cancer Mortality. AB - OBJECTIVE: This study examined whether metabolic health status is associated with risk of cancer mortality and whether this varies by body mass index (BMI) category. METHODS: A prospective study of 22,514 participants from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort was performed. Metabolically unhealthy status was defined as having three or more of the following: (1) elevated fasting glucose, (2) high triglycerides, (3) dyslipidemia, (4) hypertension, and (5) elevated waist circumference. Participants were categorized into normal weight (BMI 18.5-24.9 kg/m2 ), overweight (BMI 25.0-29.9 kg/m2 ), and obesity (BMI >= 30 kg/m2 ) groups. Cox proportional hazards regression was performed to estimate hazards ratios (HRs) and 95% confidence intervals (CIs) for cancer mortality during follow-up. RESULTS: Among participants with normal weight, participants who were metabolically unhealthy had an increased risk of cancer mortality (HR: 1.65; 95% CI: 1.20-2.26) compared with metabolically healthy participants. The overall mortality risk for participants who were metabolically unhealthy and had normal weight was stronger for obesity-related cancers (HR: 2.40; 95% CI: 1.17-4.91). Compared with participants with normal weight, those who were metabolically healthy and overweight were at a reduced risk of any cancer mortality (adjusted HR: 0.79; 95% CI: 0.63-0.99). CONCLUSIONS: There was an increased risk of overall and obesity-related cancer mortality among metabolically unhealthy participants with normal weight. PMID- 29178572 TI - Psychometric evaluation of the Arabic language person-centred climate questionnaire-staff version. AB - AIM: To evaluate the psychometric properties of the Arabic language person centred climate questionnaire-staff version. BACKGROUND: There have been increasing calls for a person-centred rather than a disease-centred approach to health care. A limited number of tools measure the extent to which care is delivered in a person-centred manner, and none of these tools have been validated for us in Arab settings. METHOD: The validated form of the person-centred climate questionnaire-staff version was translated into Arabic and distributed to 152 health care staff in teaching and non-teaching hospitals in Saudi Arabia. Statistical estimates of validity and reliability were used for psychometric evaluation. RESULTS: Items on the Arabic form of the person-centred climate questionnaire-staff version had high reliability (Cronbach's alpha .98). Cronbach's alpha values for the three sub-scales (safety, everydayness and community), were .96, .97 and .95 respectively. Internal consistency was also high and measures of validity were very good. CONCLUSION: Arabic form of the person-centred climate questionnaire-staff version provides a valid and reliable way to measure the degree of perceived person-centredness. IMPLICATIONS FOR NURSING MANAGEMENT: The tool can be used for comparing levels of person centredness between wards, units, and public and private hospitals. The tool can also be used to measure the extent of person-centredness in health care settings in other Arab countries. PMID- 29178573 TI - Macrophages-common culprit in obesity and asthma. AB - Macrophages are essential innate immune cells that also regulate local metabolism. Endogenous or exogenous stimuli may polarize macrophages toward phenotypes that serve distinct innate immunological metabolic functions. IFN gamma or lipopolysaccharide (LPS) polarizes macrophages toward the M1, or "classically activated" phenotype that participates in defense against intracellular pathogens. IL-4, IL-13, or chitin polarizes macrophages toward the M2, or "alternatively activated" phenotype, which defends against multicellular nematodes and fungi. As macrophages polarize in local environments, M1 and M2 macrophages may coexist in different organs and may differentially affect asthma and obesity, two comorbid diseases where polarized macrophages contribute to their pathogenesis. While M1 macrophages are considered beneficial in asthma and contribute to the pathology of obesity, M2 macrophages contribute to the pathology of asthma, but limit metabolic syndrome associated with obesity. Here, we discuss the roles for M1 and M2 macrophages in asthma and obesity, and propose a model by which M1-mediated inflammation in adipose tissue enhances M2-mediated inflammation in the asthmatic lung. PMID- 29178574 TI - Evidence for Triplet Sensitization in the Visible-Light-Induced [2+2] Photocycloaddition of Eniminium Ions. AB - Epsilonniminium ions were prepared from the corresponding alpha,beta-unsaturated carbonyl compounds (enones and enals), and were found to be promoted to their respective triplet states by energy transfer. The photoexcited intermediates underwent intra- or intermolecular [2+2] photocycloaddition in good yields (50-78 %) upon irradiation at lambda=433 nm or lambda=457 nm. Iridium or ruthenium complexes with a sufficiently high triplet energy were identified as efficient catalysts (2.5 mol % catalyst loading) for the reaction. The intermolecular [2+2] photocycloaddition of an eniminium ion derived from a chiral secondary amine proceeded with high enantioselectivity (88 % ee). PMID- 29178575 TI - Serum IgA/C3 and glomerular C3 staining predict severity of IgA nephropathy. AB - BACKGROUND: The aim of this study was to determine whether serum immunoglobulin A/complement factor 3 (IgA/C3) ratio and glomerular C3 staining predict outcome in IgA nephropathy. METHODS: We collected data for 44 IgA nephropathy children treated with multi-drug combination therapy. The children were retrospectively divided into four groups based on serum IgA/C3 ratio and glomerular C3 staining: group A, IgA/C3 ratio >2.68 (median) and glomerular C3 staining >=2.0, n = 9; group B, IgA/C3 ratio >2.68 and glomerular C3 staining <2.0, n = 7; group C, IgA/C3 ratio <2.68 and glomerular C3 staining >=2.0, n = 7; and group D, IgA/C3 ratio <2.68 and glomerular C3 staining <2.0, n = 21. Clinical features; pathology at the first and second renal biopsy and at the latest follow up; and prognosis were analyzed for the four groups. RESULTS: At the most recent follow up, urinary protein excretion, incidence of hematuria, and serum creatinine in group A were all higher than in group D. At the second biopsy, crescent absence/presence ratio; mesangial hypercellularity, segmental glomerulosclerosis or adhesion, endocapillary hypercellularity, and tubular atrophy/interstitial fibrosis as well as crescents and global glomerulosclerosis (MESTCG) score; and clonicity index in group A were higher than in group D. All patients in group D had normal urine, and the prevalence of persistent nephropathy in group A was higher than in group D. CONCLUSIONS: Serum IgA/C3 ratio and glomerular C3 staining can predict outcome in IgA nephropathy. PMID- 29178576 TI - The misunderstood TIGER. PMID- 29178577 TI - Dispersive magnetic solid-phase extraction of phthalate esters from water samples and human plasma based on a nanosorbent composed of MIL-101(Cr) metal-organic framework and magnetite nanoparticles before their determination by GC-MS. AB - In this study, a magnetic metal-organic framework was synthesized simply and utilized in the dispersive magnetic solid-phase extraction of five phthalate esters followed by their determination by gas chromatography with mass spectrometry. First, MIL-101(Cr) was prepared hydrothermally in water medium without using highly corrosive hydrofluoric acid, utilizing an autoclave oven heat supply. Afterward, Fe3 O4 nanoparticles were decorated into the matrix of MIL-101(Cr) to fabricate magnetic MIL-101 nanocomposite. The nanocomposite was characterized by various techniques. The parameters affecting dispersive magnetic solid-phase extraction efficiency were optimized and obtained as: a sorbent amount of 15 mg; a sorption time of 20 min; an elution time of 5 min; NaCl concentration, 10% w/v; type and volume of the eluent 1 mL n-hexane/acetone (1:1 v/v). Under the optimum conditions detection limits and linear dynamic ranges were achieved in the range of 0.08-0.15 and 0.5-200 MUg/L, respectively. The intra- and interday RSD% values were obtained in the range of 2.5-9.5 and 4.6 10.4, respectively. Ultimately, the applicability of the method was successfully confirmed by the extraction and determination of the model analytes in water samples, and human plasma in the range of microgram per liter and satisfactory results were obtained. PMID- 29178578 TI - Trends in maternal deaths in HIV-infected women, on a background of changing HIV management guidelines in South Africa: 1997 to 2015. AB - INTRODUCTION: As work begins towards the Sustainable Development Goal target of reducing the global maternal mortality ratio (MMR) to less than 70 deaths per 100,000 live births by 2030, much needs to be done in ending preventable maternal deaths. After 1990, South Africa experienced a reversal of gains in decreasing maternal mortality, with an increase in HIV-related maternal deaths. In this study, we assessed trends in maternal mortality in HIV-infected women, on a background of an evolving HIV care programme. METHODS: This was a cross sectional, retrospective record review of maternal deaths in the obstetrics unit at Chris Hani Baragwanath Academic Hospital, in Johannesburg, South Africa, a referral hospital in a high HIV prevalence setting where the prevalence among pregnant women has plateaued around 29.0% for the past decade. Trends in HIV diagnosis and management in pregnancy, and causes of maternal deaths in HIV infected women were analysed over different time periods (1997 to 2003, 2004 to 2009, 2010 to 2012, and 2013 to 2015) reflecting major guideline changes. RESULTS: From January 1997 to December 2015, there were 692 maternal deaths in the obstetrics unit. Of the 490 (70.8%) maternal deaths with a documented HIV status, 335 (68.4%) were HIV-infected. A Chi-squared test for trends showed that the institutional MMR (iMMR) in women known to be HIV-infected peaked in the period 2004 to 2009 at 380 (95% CI 319 to 446) per 100,000 live births, with a decline to 267 (95% CI 198 to 353) in 2013 to 2015, p = 0.049. This decrease coincided with changes in the South African HIV management guidelines, mainly increased availability of antiretroviral therapy (ART). Non-pregnancy related infections were the leading cause of death throughout the review period, accounting for 61.5% (206/335) of deaths. Only 23.3% (78/335) of the women who died were on ART at the time of death, this in the context of advanced immune suppression and an overall median CD4 count of 136 cells/MUl (interquartile ranges (IQR) 45 to 301). CONCLUSION: In this 19-year review of maternal deaths in Johannesburg, South Africa, there was evidence of a decrease in the iMMR among HIV-infected women, but it remains unacceptably high. Efforts to address drivers of mortality and barriers to accessing ART need to be accelerated if we are to see substantial decreases in maternal mortality. PMID- 29178579 TI - Vitamin D receptor expression in canine mammary gland and relationship with clinicopathological parameters and progesterone/oestrogen receptors. AB - The vitamin D receptor (VDR) belongs to the nuclear class II receptor family. VDR is a ligand transcription factor and mediates the actions of calcitriol, the active product of vitamin D synthesis. Nowadays, it is known that the biological actions of calcitriol include the capacity to modulate cancer features, such as proliferation and differentiation, apoptosis, angiogenesis, invasion and metastasis. VDR expression has been demonstrated in human breast cancer and vitamin D has emerged as a promising targeted therapy. We analyse the VDR expression in normal and neoplastic canine mammary tissue samples and its relationship with clinicopathological parameters and progesterone/oestrogens receptors (PR/ER). Expression of VDR, Ki67 (to evaluate the proliferation index, PI), PR and ER was assessed in 50 mammary gland tissue samples from 41 female dogs by immunohistochemistry. VDR-positive staining was found in the nuclei of both myoepithelial and luminal epithelial cell layers. VDR expression was higher in normal mammary tissue (37/37 cases, 100%) then followed by benign tumours (6/15 cases, 40%) and malignant tumours (9/34 cases, 26.5%) (P = .001). Female dogs aged >=10 years had lower VDR expression compared with dogs younger (P = .017). Relationship between VDR and breed, number of tumours, tumour size, histologic subtype, histologic grade of malignancy, PI and PR and ER expression was not observed. Studies with more samples are necessary to further evaluate the possible role of VDR in the biological behaviour of canine mammary tumours, and to corroborate the possibility to use the dog as model for human breast cancer. PMID- 29178581 TI - The Irrelevance of Getting Stronger or Weaker with Age. PMID- 29178580 TI - A cell-free platform for rapid synthesis and testing of active oligosaccharyltransferases. AB - Protein glycosylation, or the attachment of sugar moieties (glycans) to proteins, is important for protein stability, activity, and immunogenicity. However, understanding the roles and regulations of site-specific glycosylation events remains a significant challenge due to several technological limitations. These limitations include a lack of available tools for biochemical characterization of enzymes involved in glycosylation. A particular challenge is the synthesis of oligosaccharyltransferases (OSTs), which catalyze the attachment of glycans to specific amino acid residues in target proteins. The difficulty arises from the fact that canonical OSTs are large (>70 kDa) and possess multiple transmembrane helices, making them difficult to overexpress in living cells. Here, we address this challenge by establishing a bacterial cell-free protein synthesis platform that enables rapid production of a variety of OSTs in their active conformations. Specifically, by using lipid nanodiscs as cellular membrane mimics, we obtained yields of up to 420 MUg/ml for the single-subunit OST enzyme, "Protein glycosylation B" (PglB) from Campylobacter jejuni, as well as for three additional PglB homologs from Campylobacter coli, Campylobacter lari, and Desulfovibrio gigas. Importantly, all of these enzymes catalyzed N-glycosylation reactions in vitro with no purification or processing needed. Furthermore, we demonstrate the ability of cell-free synthesized OSTs to glycosylate multiple target proteins with varying N-glycosylation acceptor sequons. We anticipate that this broadly applicable production method will advance glycoengineering efforts by enabling preparative expression of membrane-embedded OSTs from all kingdoms of life.

PMID- 29178583 TI - Bariatric Surgery and the Incidence of Psoriasis and Psoriatic Arthritis in the Swedish Obese Subjects Study. AB - OBJECTIVE: The aim of this study was to assess the effect of bariatric surgery (vertical gastroplasty, gastric banding, or gastric bypass) compared with usual care on the incidence of psoriasis and psoriatic arthritis (PsA) in the Swedish Obese Subjects study. METHODS: This report includes 1,991 subjects who underwent bariatric surgery and 2,018 controls with obesity from the SOS study; none of them had psoriasis or PsA at baseline. Information about psoriasis and PsA diagnosis was retrieved through the Swedish National Patient Register and questionnaires. RESULTS: During follow-up for up to 26 years, bariatric surgery was associated with a lower incidence of psoriasis compared with usual care (number of events = 174; hazard ratio 0.65; 95% CI: 0.47-0.89; P = 0.008). Both smoking and a longer duration of obesity were independently associated with a higher risk for psoriasis. No significant difference was detected among the three surgical procedures in terms of lowering the risk of developing psoriasis. The association between bariatric surgery and psoriasis incidence was not influenced by baseline confounders. No significant difference in the risk of developing PsA (number of events = 46) was detected when comparing the surgery and the control groups. CONCLUSIONS: This study shows that bariatric surgery is associated with a lower risk of developing psoriasis compared with usual care. PMID- 29178584 TI - Age Variation in the Association Between Obesity and Mortality in Adults. AB - OBJECTIVE: The aim of this study was to evaluate the previously reported finding that the association between obesity and mortality strengthens with increasing age. METHODS: The data were derived from the National Health Interview Survey. Age-specific hazard ratios of mortality for grade 2/3 obesity (BMI >= 35 kg/m2 ), relative to a BMI of 18.5 kg/m2 to < 25 kg/m2 , were calculated by using a flexible parametric survival model (240,184 white men) and Cox proportional hazard models (51,697 matched pairs). RESULTS: When the model included interaction terms between obesity and age at the survey, hazard ratios appeared to increase with age if those interaction terms were ignored by fixing age at the survey as a single value. However, when recalculated for adults with various ages at the survey, according to model specifications, hazard ratios were higher for younger adults than for older adults with the same follow-up duration. Based on matched data, hazard ratios were also higher for younger adults (2.14 [95% CI: 1.90-2.40] for those 40-49 years of age) than for older adults (1.22 [95%: 0.91 1.63] for those 90+ years of age). CONCLUSIONS: For any given follow-up duration, the association between obesity and mortality weakens with age. The previously reported strengthening of the obesity-mortality association with increasing age was caused by the failure to take all the model specifications into consideration when calculating adjusted hazard ratios.

AB - The treatment of non-small cell lung cancer (NSCLC) is currently experiencing a revolution. Over the last decade, the knowledge gained about the biochemical features of biomarkers and their predictive abilities has led to the development of targeted small-molecule inhibitors that present an alternative to harsh chemotherapy. The use of these new therapies has improved the quality of life and increased the survival of patients. The occurrence of inevitable drug resistance requires the constant development of precision medicine. The detailed understanding of the target biology and the search for innovative chemical approaches has encouraged investigations in this field. Herein, we review selected aspects of the molecular targets and present an overview of current topics and challenges in the rational development of small molecules to target NSCLC. PMID- 29178585 TI - Volumetric-modulated arc therapy versus intensity-modulated radiotherapy for large volume retroperitoneal sarcomas: A comparative analysis of dosimetric and treatment delivery parameters. AB - PURPOSE: To compare dosimetric and treatment delivery parameter differences between volumetric-modulated arc radiotherapy (VMAT) and intensity-modulated radiotherapy (IMRT) for large volume retroperitoneal sarcomas (RPS). MATERIALS AND METHODS: Both VMAT and IMRT planning were performed on CT datasets of 10 patients with RPS who had been previously treated with preoperative radiotherapy. Plans were optimized to deliver >=95% dose to the PTV and were evaluated for conformity and homogeneity. Dose to the organs at risk (OARs) (kidney, liver, spinal cord, and bowel space), unspecified tissue, and dose evaluation volumes (DEVs) at 1, 2, and 5 cm from PTV were calculated and compared. Monitor units (MUs) and treatment delivery times were recorded and compared between the two techniques. The deliverability of the large volume RPS VMAT plans was verified by portal dosimetry on a TruebeamTM linac. RESULTS: VMAT and IMRT plans were equivalent for PTV coverage and homogeneity (P > 0.05); however, VMAT plans had slightly better conformity index, CI (P < 0.001). Doses to the OARs were not significantly different between VMAT and IMRT plans (P > 0.05). Mean doses to the unspecified tissue as well as at 1, 2, and 5 cm DEVs were lower with VMAT compared with IMRT, P = 0.04 and P < 0.01, respectively. MUs and average beam-on times were both significantly lower in the VMAT vs IMRT plans, P < 0.001 and P = 0.001, respectively. All VMAT plans passed portal dosimetry delivery verification with an average gamma passing rate of 99.6 +/- 0.4%. CONCLUSIONS: VMAT planning for large volume RPS improved CI, and achieved comparable OAR sparing, as compared with IMRT. As treatment delivery time was lower, the use of VMAT for RPS may translate into improved treatment delivery efficiency. PMID- 29178587 TI - Self-clotting method improves cell block preparation. AB - BACKGROUND: The success of cell block preparation is crucial for ancillary diagnostic tests in cytology. However, achieving an optimal cell block can be challenging. The current study describes a self-clotting-based technique for fine needle aspiration (FNA) cell block preparations and evaluates its usefulness in comparison with the conventional needle wash technique. METHODS: The clinical data, FNA procedure, and cellularity of cell blocks of the self-clotting group (37 cases) and the conventional needle wash group (33 cases) were compared. The cellularity was evaluated using a scoring system (0 indicated acellular, 1 indicated 1-50 cells, and 2 indicated >50 cells). RESULTS: Approximately 76% of cases in the self-clotting group received a score of 2 versus 36% in the conventional needle wash group. Approximately 14% received a score of 1 in the self-clotting group compared with 9% in the conventional needle wash group, whereas 11% in the self-clotting group received a score of 0 versus 55% in the conventional needle wash group. The differences between the 2 methods were statistically significant. CONCLUSIONS: The results of the current study demonstrate that the self-clotting method is superior to the conventional needle wash method for FNA samples. Cancer Cytopathol 2018;126:190-9.

AB - For the past few decades, nanoparticles of various sizes, shapes, and compositions have been synthesized and utilized in many different applications. However, due to a lack of analytical tools that can characterize structural changes at the nanoscale level, many of their growth and transformation processes are not yet well understood. The recently developed technique of liquid-phase transmission electron microscopy (TEM) has gained much attention as a new tool to directly observe chemical reactions that occur in solution. Due to its high spatial and temporal resolution, this technique is widely employed to reveal fundamental mechanisms of nanoparticle growth and transformation. Here, the technical developments for liquid-phase TEM together with their application to the study of solution-phase nanoparticle chemistry are summarized. Two types of liquid cells that can be used in the high-vacuum conditions required by TEM are discussed, followed by recent in situ TEM studies of chemical reactions of colloidal nanoparticles. New findings on the growth mechanism, transformation, and motion of nanoparticles are subsequently discussed in detail. PMID- 29178588 TI - Early barriers to neonatal porcine islet engraftment in a dual transplant model. AB - Porcine islet xenografts have the potential to provide an inexhaustible source of islets for beta cell replacement. Proof-of-concept has been established in nonhuman primates. However, significant barriers to xenoislet transplantation remain, including the poorly understood instant blood-mediated inflammatory reaction and a thorough understanding of early xeno-specific immune responses. A paucity of data exist comparing xeno-specific immune responses with alloislet (AI) responses in primates. We recently developed a dual islet transplant model, which enables direct histologic comparison of early engraftment immunobiology. In this study, we investigate early immune responses to neonatal porcine islet (NPI) xenografts compared with rhesus islet allografts at 1 hour, 24 hours, and 7 days. Within the first 24 hours after intraportal infusion, we identified greater apoptosis (caspase 3 activity and TUNEL [terminal deoxynucleotidyl transferase dUTP nick end labeling])-positive cells) of NPIs compared with AIs. Macrophage infiltration was significantly greater at 24 hours compared with 1 hour in both NPI (wild-type) and AIs. At 7 days, IgM and macrophages were highly specific for NPIs (alpha1,3-galactosyltransferase knockout) compared with AIs. These findings demonstrate an augmented macrophage and antibody response toward xenografts compared with allografts. These data may inform future immune or genetic manipulations required to improve xenoislet engraftment. PMID- 29178591 TI - Complementarity of stability patches at the interfaces of protein complexes: Implication for the structural organization of energetic hot spots. AB - A rational design of protein complexes with defined functionalities and of drugs aimed at disrupting protein-protein interactions requires fundamental understanding of the mechanisms underlying the formation of specific protein complexes. Efforts to develop efficient small-molecule or protein-based binders often exploit energetic hot spots on protein surfaces, namely, the interfacial residues that provide most of the binding free energy in the complex. The molecular basis underlying the unusually high energy contribution of the hot spots remains obscure, and its elucidation would facilitate the design of interface-targeted drugs. To study the nature of the energetic hot spots, we analyzed the backbone dynamic properties of contact surfaces in several protein complexes. We demonstrate that, in most complexes, the backbone dynamic landscapes of interacting surfaces form complementary "stability patches," in which static areas from the opposing surfaces superimpose, and that these areas are predominantly located near the geometric center of the interface. We propose that a diminished enthalpy-entropy compensation effect augments the degree to which residues positioned within the complementary stability patches contribute to complex affinity, thereby giving rise to the energetic hot spots. These findings offer new insights into the nature of energetic hot spots and the role that backbone dynamics play in facilitating intermolecular recognition. Mapping the interfacial stability patches may provide guidance for protein engineering approaches aimed at improving the stability of protein complexes and could facilitate the design of ligands that target complex interfaces. PMID- 29178590 TI - Meloxicam inhibits biofilm formation and enhances antimicrobial agents efficacy by Pseudomonas aeruginosa. AB - Microbial biofilms are communities of surface-adhered cells enclosed in a matrix of extracellular polymeric substances. Bacterial cells in biofilm are 10~1,000 fold more resistant to antimicrobials than the planktonic cells. Burgeoning antibiotic resistance in Pseudomonas aeruginosa biofilm has necessitated the development of antimicrobial agents. Here, we have investigated the antibiofilm effect of meloxicam against P. aeruginosaPAO1 and its potential mechanisms. Further, we have explored whether meloxicam could enhance the susceptibility of bacterial biofilms to treatment with conventional antimicrobials. Here, we found that meloxicam could significantly inhibit PAO1 biofilm formation in a dose dependent manner at the concentration without influence on planktonic cell growth. Meloxicam could also significantly inhibit the motilities, production of extracellular matrix, and expression of quorum sensing-related genes and virulence factors of PAO1. Furthermore, synergistic interaction was observed when meloxicam combined with tetracycline, gentamicin, tobramycin, ciprofloxacin, ceftriaxone, ofloxacin, norfloxacin, ceftazidime, and DNase at subminimal inhibitory concentrations against PAO1 bioiflm. Collectively, our study lays the foundation for further investigation of repurposing meloxicam as a topical antibiofilm agent to treat P. aeruginosa biofilm-related infections. PMID- 29178592 TI - A 3D Covalent Organic Framework with Exceptionally High Iodine Capture Capability. AB - Using porous materials to cope with environmental issues is promising but remains a challenge especially for removing the radioactive vapor wastes in fission because of harsh adsorption conditions. Here we report a new, stable covalent organic framework (COF) as a porous platform for removing iodine vapor-a major radioactive fission waste. The three-dimensional COF consists of a diamond topology knotted by adamantane units, creates ordered one-dimensional pores and are highly porous. The COF enables the removal of iodine vapor via charge transfer complex formation with the pore walls to achieve exceptional capacity. Moreover, the 3D COF is "soft" to trigger structural fitting to iodine while retaining connectivity and enables cycle use for many times while retaining high uptake capacity. These results set a new benchmark for fission waste removal and suggest the great potential of COFs as a designable porous material for challenging world-threatening pollution issues.

PMID- 29178594 TI - Cu(OAc)2 /TEMPO Cooperative Promoted Hydroamination Cyclization and Oxidative Dehydrogenation Cascade Reaction of Homopropargylic Amines. AB - A novel and efficient Cu(OAc)2 -catalyzed hydroamination cyclization and 2,2,6,6 tetramethylpiperidine-1-oxyl (TEMPO)-mediated oxidative dehydrogenation cascade reaction of homopropargylic amines has been developed. A library of 1,2 disubstituted pyrrole derivatives were obtained in good-to-high yields in one pot with no step-by-step feeding process. This reaction involved TEMPO playing dual roles as both an oxidative dehydrogenation reagent and a ligand. An insight into the reaction mechanism was obtained by using several analytical determination methods. PMID- 29178595 TI - A simplified Monte Carlo algorithm considering large-angle scattering for fast and accurate calculation of proton dose. AB - PURPOSE: The purpose of this study is to improve dose calculation accuracy of the simplified Monte Carlo (SMC) algorithm in the low-dose region. Because conventional SMC algorithms calculate particle scattering in consideration of multiple Coulomb scattering (MCS) only, they approximate lateral dose profiles by a single Gaussian function. However, it is well known that the low-dose region spreads away from the beam axis, and it has been pointed out that modeling of the low-dose region is important to calculated dose accurately. METHODS: A SMC algorithm, which is named modified SMC and considers not only MCS but also large angle scattering resembling hadron elastic scattering, was developed. In the modified SMC algorithm, the particle fluence varies in the longitudinal direction because the large-angle scattering decreases residual range of particles in accordance with their scattering angle and tracking of the particles with large scattering angle is terminated at a short distance downstream from the scattering. Therefore, modified integrated depth dose (m-IDD) tables, which are converted from measured IDD in consideration of the fluence loss, are used to calculate dose. RESULTS: In the case of a 1-liter cubic target, the calculation accuracy was improved in comparison with that of a conventional algorithm, and the modified algorithm results agreed well with Geant4-based simulation results; namely, 98.8% of the points satisfied the 2% dose/2 mm distance-to-agreement (DTA) criterion. The calculation time of the modified SMC algorithm was 1972 s in the case of 4.4 * 108 particles and 16-threading operation of an Intel Xeon E5 2643 (3.3-GHz clock). CONCLUSIONS: An SMC algorithm that can reproduce a laterally widespread low-dose region was developed. According to the comparison with a Geant4-based simulation, it was concluded that the modified SMC algorithm is useful for calculating dose of proton radiotherapy. PMID- 29178596 TI - Knowledge and attitudes toward transgender health. AB - BACKGROUND: Hormonal interventions for transgender adolescents have become increasingly common; however, there is a paucity of research on medical student knowledge of, and attitudes toward, these interventions following didactic instruction. Furthermore, no studies have examined whether students can be aware of the literature on the mental health benefits of these treatments yet continue to find them unethical. METHODS: An anonymous online survey was administered to students, from first to fourth year (n = 407), who had received one or two lectures on the treatment of youths with gender dysphoria (GD). RESULTS: Surveys were completed by 162 respondents (40%). A majority was able to correctly answer questions regarding psychiatric co-morbidities, diagnostic criteria, hormonal interventions, long-term benefits of interventions and terminology. There was some evidence that precision in the use of terminology waned over time. Many were unclear on the role of puberty blockers and the time requirement for a diagnosis of GD. A minority (14%) reported a belief that hormonal therapy is unethical, although these same individuals recognised that these treatments have mental health benefits. DISCUSSION: Our results have implications for future instruction, including: the need to teach pharmacological and diagnostic issues more deliberately; providing refresher training on terminology; and relying on interactive discussion or patient visits, rather than didactic lectures alone, for ethically charged medical topics. Similar levels of knowledge among students who believe that hormonal therapy is ethical and unethical may indicate that imparting didactic knowledge about therapeutic benefits alone may not be sufficient to affect attitudes regarding endocrine care for transgender youth. Hormonal interventions for transgender adolescents have become increasingly common. PMID- 29178598 TI - Workplace bullying and burnout among healthcare employees: The moderating effect of control-related resources. AB - Workplace bullying is a widespread and challenging problem in healthcare organizations, bearing negative consequences for individuals and organizations. Drawing on the job demands-resources theory, in this study, we examined the relationship between workplace bullying and burnout among healthcare employees, as well as the moderating role of job autonomy and occupational self-efficacy in this relationship. Using a cross-sectional design with anonymous questionnaires, data were collected from two samples of 309 healthcare employees in a mental health facility, and 105 nurses studying for their bachelor degree in health systems administration. The findings indicated that workplace bullying was positively related to burnout dimensions, and that this relationship was moderated by job autonomy and occupational self-efficacy resources. Job autonomy interacted with workplace bullying in predicting emotional exhaustion and depersonalization; the interaction of bullying with occupational self-efficacy significantly predicted depersonalization. These results underscore the importance of control-related resources in mitigating the harmful effects of workplace bullying on employees. Implications for research and managerial practices are discussed. PMID- 29178597 TI - Body size and allometric variation in facial shape in children. AB - OBJECTIVES: Morphological integration, or the tendency for covariation, is commonly seen in complex traits such as the human face. The effects of growth on shape, or allometry, represent a ubiquitous but poorly understood axis of integration. We address the question of to what extent age and measures of size converge on a single pattern of allometry for human facial shape. METHODS: Our study is based on two large cross-sectional cohorts of children, one from Tanzania and the other from the United States (N = 7,173). We employ 3D facial imaging and geometric morphometrics to relate facial shape to age and anthropometric measures. RESULTS: The two populations differ significantly in facial shape, but the magnitude of this difference is small relative to the variation within each group. Allometric variation for facial shape is similar in both populations, representing a small but significant proportion of total variation in facial shape. Different measures of size are associated with overlapping but statistically distinct aspects of shape variation. Only half of the size-related variation in facial shape can be explained by the first principal component of four size measures and age while the remainder associates distinctly with individual measures. CONCLUSIONS: Allometric variation in the human face is complex and should not be regarded as a singular effect. This finding has important implications for how size is treated in studies of human facial shape and for the developmental basis for allometric variation more generally. PMID- 29178599 TI - Gut Microbiome-Induced Shift of Acetate to Butyrate Positively Manages Dysbiosis in High Fat Diet. AB - SCOPE: A recent study revealed that the accumulation of gut microbiota-produced acetate (GMPA) led to insulin over-secretion and obesity symptom. To further develop this scientific point, the effect of resistant starch (RS) or exogenous acetate carried by RS (RSA) in the gut on metabolic syndrome is investigated using diet-induced obese rats. METHODS AND RESULTS: The metabonomics analysis shows that the gut of rats in the RSA group generate more butyrate in both serum and feces rather than acetate compared to the rats in RS group, indicating the conversion among metabolites, in particular from acetate to butyrate via gut microbiota. Consistently, the gut microbiome uses acetate as a substrate to produce butyrate, such as Coprococcus, Faecalibacterium, Roseburia, and Eubacterium and was highly promoted in RSA group, which further supports the metabolic conversion. This is the first report to reveal the accumulation of gut microbiota-produced butyrate (GMPB) but not GMPA significantly enriched AMPK signaling pathway with reduced expression of lipogenesis-associated genes for suppressing sphingosines and ceramides biosynthesis to trigger insulin sensitivity. CONCLUSION: Gut microbiome profile and lipogenesis pathway are regulated by GMPB, which substantially influences energy harvesting in the gut from patterns opposed to GMPA. PMID- 29178600 TI - Genetic Markers of Brown Adipose Tissue Identity and In Vitro Brown Adipose Tissue Activity in Humans. AB - OBJECTIVE: Human brown adipose tissue (BAT) activity decreases with age and obesity. In addition to uncoupling protein 1 (UCP1), several genetic markers of BAT in humans have been published. However, the link between human BAT activity and genetic markers has been inadequately explored. METHODS: White adipose tissue (WAT) and BAT biopsies were obtained from 16 patients undergoing deep neck surgery. In vitro differentiated adipocytes were used to measure norepinephrine stimulated mitochondrial uncoupling as a measure of in vitro BAT activity. Gene expression was determined in adipose tissue biopsies. RESULTS: Norepinephrine increased in vitro BAT activity in adipocytes derived from human BAT, and this increase was abolished by propranolol. Furthermore, in vitro BAT activity showed a negative correlation to age and BMI. UCP1 messenger RNA (mRNA) expression showed a positive correlation to in vitro BAT activity, while zinc finger protein of cerebellum 1 (ZIC1) mRNA showed a negative correlation to in vitro BAT activity. In human BAT biopsies, UCP1 mRNA showed negative correlations to age and BMI, while ZIC1 mRNA showed positive correlations to age and BMI. CONCLUSIONS: Differentiated adipocytes derived from human BAT maintain intrinsic characteristics of the donor. High ZIC1 mRNA does not necessarily reflect high BAT activity. PMID- 29178601 TI - The prevalence, risk factors, and outcomes of medication trade-offs in kidney and liver transplant recipients: a pilot study. AB - High out-of-pocket medication costs negatively impact adherence in transplantation. We evaluated the association of "medication trade-offs"-defined as choosing to spend money on other expenses over medications-with medication nonadherence and transplant outcomes. From 2011 to 2012, we performed a prospective study of 201 transplanted recipients (n = 103 liver, n = 98 kidney and) at two large US transplant centers. Structured interviews assessed socio demographics, medication adherence, and medication trade-offs. Multivariable models assessing risk factors for medications trade-offs and the association between medications trade-offs and post-transplant hospital admissions were performed. A total of 17% of patients reported medication trade-offs; the most common trade-offs were inability to afford a prescription in the past 12 months and making choices between prescriptions and food. In multivariable analysis, insurance type (RR: 2.97, 95% CI: 1.19-7.40), limited health literacy (RR: 2.64, 95% CI: 1.23-5.64), and >=3 comorbid conditions (RR: 2.48, 95% CI: 1.09-5.62; all P < 0.05) were associated with trade-offs. Patients with trade-offs were more likely to report nonadherence to medications (mean adherence: 77 +/- 23% with trade-offs vs. 89 +/- 19% without trade-offs, P < 0.01). The presence of medication trade-offs was associated with post-transplant hospital admissions (RR 1.64, 95% CI 1.14-2.35, P < 0.01). Assessments of financial barriers are warranted in clinical practice to identify nonadherence and improve post transplant outcomes. PMID- 29178602 TI - Should consultation recording use be a practice standard? A systematic review of the effectiveness and implementation of consultation recordings. AB - OBJECTIVE: To conduct a systematic review of the effectiveness of consultation recordings and identify factors contributing to their successful implementation in health-care settings. METHODS: A systematic review was conducted for quantitative studies examining the effectiveness of consultation recordings in health care. Two independent reviewers assessed the relevance and quality of retrieved quantitative studies by using standardized criteria. Study findings were examined to determine consultation recording effectiveness and to identify barriers and facilitators to implementation. A supplementary review of qualitative evidence was performed to further explicate implementation factors. RESULTS: Of the 3373 articles retrieved in the quantitative search, 26 satisfied the standardized inclusion criteria (12 randomized controlled trials, 1 quasi experiment, and 13 cross-sectional studies). Most patients found consultation recordings beneficial. Statistically significant evidentiary support was found for the beneficial impact of consultation recordings on the following patient reported outcomes: knowledge, perception of being informed, information recall, decision-making factors, anxiety, and depression. Implementation barriers included strength of evidence concerns, patient distress, impact of the recording on consultation quality, clinic procedures, medico-legal issues, and resource costs. Facilitators included comfort with being recorded, clinical champions, legal strategies, efficient recording procedures, and a positive consultation recording experience. CONCLUSIONS: Consultation recordings are valuable to patients and positively associated with patient-reported outcomes. Successful integration of consultation recording use into clinical practice requires an administratively supported, systematic approach to addressing implementation factors. PMID- 29178603 TI - Targeted next-generation sequencing and parental genotyping in sporadic Chinese Han deaf patients. AB - The interpretation of the targeted next-generation sequencing (NGS) results can be challenging for variants identified in the sporadic deaf patients. In this study, we performed targeted NGS of 143 deafness-associated genes in 44 sporadic deaf patients and use parental genotyping to test whether the candidate pathogenic variants complied with recessive or de novo pattern. Of 29 recessive candidate variants with minor allele frequencies (MAFs) less than 0.005, 3 pairs of apparent compound heterozygous variants were inherited from the same parental allele, ruling out their pathogenic roles. In addition, non-segregation of an OTOA p.Gln293Arg variant led to the discovery of a genomic microdeletion of OTOA on the opposite allele by copy number variation analysis. Overall, 13 pairs of recessive candidate variants were deemed causative in 13 patients. Of the 28 dominant candidate variants with MAFs less than 0.0005, none occurred de novo, suggesting that they were not disease causing. Our results revealed that targeted NGS in sporadic deaf patients may generate a significant false-positive rate. Parental genotyping is a simple but effective step toward minimizing the false positive results. Our study also showed that de novo variants in dominant deafness genes may not be a common cause for sporadic deafness. PMID- 29178604 TI - Examining polyquaternium polymers deposition on human excised hair fibers. AB - BACKGROUND: Polyquaterniums (PQs) as important ingredients of hair products are synthetic cationic polymers and are used in commercial hair volumizers and conditioners. METHODS: Three different grades of polymers including PQ 87, 68, and 46 with various concentrations were used, and their hair deposition efficacy was measured at 5 different pH values using hair diameters measurements by digital micrometer. Deposition durability of polymer layer on the hair surface was tested by a defined washing test. Optical microscopic images and polarized light images were also taken from treated and untreated samples for further investigation. Attenuated total reflectance (ATR) spectral were recorded from hair samples to prove the polymer deposition and probable interaction with hair fibers. RESULTS: PQ-68 with the highest molecular weight (300 kDa) at pH = 9 exhibited the best hair deposition efficacy. The results revealed that the deposition of polymers is directly proportional to the pH values. The best results were seen at pH = 9, and at the lowest pH (pH = 5), the efficiency of polymers was approximately equal to zero. The best resistance against washing was shown by PQ-44 at pH = 6. ATR successfully tracked the presence of the polymers on the hair fibers and also proposed specific wave numbers for each polymeric agent, individually. CONCLUSIONS: In general, two main parameter which can mainly influence the deposition efficacy of PQs are the type of polymer or its molecular weight and also the positive charge density on the polymer molecules. PMID- 29178605 TI - RECORDS: improved Reporting of montE CarlO RaDiation transport Studies: Report of the AAPM Research Committee Task Group 268. AB - Studies involving Monte Carlo simulations are common in both diagnostic and therapy medical physics research, as well as other fields of basic and applied science. As with all experimental studies, the conditions and parameters used for Monte Carlo simulations impact their scope, validity, limitations, and generalizability. Unfortunately, many published peer-reviewed articles involving Monte Carlo simulations do not provide the level of detail needed for the reader to be able to properly assess the quality of the simulations. The American Association of Physicists in Medicine Task Group #268 developed guidelines to improve reporting of Monte Carlo studies in medical physics research. By following these guidelines, manuscripts submitted for peer-review will include a level of relevant detail that will increase the transparency, the ability to reproduce results, and the overall scientific value of these studies. The guidelines include a checklist of the items that should be included in the Methods, Results, and Discussion sections of manuscripts submitted for peer review. These guidelines do not attempt to replace the journal reviewer, but rather to be a tool during the writing and review process. Given the varied nature of Monte Carlo studies, it is up to the authors and the reviewers to use this checklist appropriately, being conscious of how the different items apply to each particular scenario. It is envisioned that this list will be useful both for authors and for reviewers, to help ensure the adequate description of Monte Carlo studies in the medical physics literature. PMID- 29178606 TI - Empowering students with the hidden curriculum. AB - BACKGROUND: The hidden curriculum (HC) refers to unscripted, ad hoc learning that occurs outside the formal, taught curriculum and can have a powerful influence on the professional development of students. While this learning may be positive, it may conflict with that taught in the formal curriculum. Medical schools take a range of steps to address these negative effects; however, the existence and nature of the concept tends to be hidden from students. METHODS: Since 2007, our medical school has incorporated into its small group programme an educational activity exploring the concept of the hidden curriculum. We undertook a qualitative evaluation of our intervention, conducting a thematic analysis of students' wiki reflections about the HC. We also analysed students' responses to a short questionnaire about the educational approach used. FINDINGS: The majority of students felt that the HC session was important and relevant. Most appeared able to identify positive and negative HC experiences and consider how these might influence their learning and development, although a few students found the concept of the HC hard to grasp. DISCUSSION: Revealing and naming the hidden curriculum can make students aware of its existence and understand its potential impact. The hidden curriculum may also be a useful tool for triggering debate about issues such as power, patient centredness, personal resilience and career stereotypes in medicine. Supporting students to think critically about HC experiences may empower them to make active choices about which messages to take on board. The hidden curriculum can have a powerful influence on the professional development of students. PMID- 29178607 TI - Detection and clinical impact of human leukocyte antigen antibodies in lung transplantation: A systematic review and meta-analysis. AB - There is significant variability in lung transplant centers' approach to HLA antibodies, creating heterogeneity regarding their clinical significance. Some institutions use beads coated with multiple HLA to screen candidate sera and then use single antigen bead (SAB) to determine antibody identity if the pre-screen is positive. Other centers do not pre-screen, using SAB alone, which may detect low level antibodies of unknown significance. The primary objective of this study was to review the current literature to identify sources of heterogeneity in the identification of pre- and post-lung transplant HLA antibodies, particularly regarding antibody-detection methods. A random effects model meta-analysis was used to evaluate the relationship between pre-transplant HLA antibodies and the development of de novo donor-specific antibodies (dnDSA) and dnDSA and chronic lung allograft dysfunction (CLAD). Each outcome was stratified by the method of antibody detection (pre-screen followed by SAB vs SAB alone). We identified 13 cohort studies with a total of 3039 patients. The use of pre-screening followed by SAB testing and the use of induction immunosuppression were associated with lower prevalence of dnDSA. Patients with pre-transplant HLA antibodies were more likely to develop dnDSA (hazard ratio [HR] = 1.49, 95% confidence interval [CI]: 1.19-1.86, P < .001). dnDSA was associated with CLAD (HR = 2.02, 95% CI = 1.37 2.97, P < .001). When considering studies using SAB alone, however, pre transplant antibody status was no longer associated with dnDSA and dnDSA was no longer associated with CLAD. Based on the current literature, SAB-alone testing may detect less clinically relevant antibodies than pre-screening followed by SAB.

PMID- 29178609 TI - Phosphonate-Mediated Immobilization of Rhodium/Bipyridine Hydrogenation Catalysts. AB - RhL2 complexes of phosphonate-derivatized 2,2'-bipyridine (bpy) ligands L were immobilized on titanium oxide particles generated in situ. Depending on the structure of the bipy ligand-number of tethers (1 or 2) to which the phosphonate end groups are attached and their location on the 2,2'-bipyridine backbone (4,4' , 5,5'-, or 6,6'-positions)-the resulting supported catalysts showed comparable chemoselectivity but different kinetics for the hydrogenation of 6-methyl-5 hepten-2-one under hydrogen pressure. Characterization of the six supported catalysts suggested that the intrinsic geometry of each of the phosphonate derivatized 2,2'-bipyridines leads to supported catalysts with different microstructures and different arrangements of the RhL2 species at the surface of the solid, which thereby affect their reactivity. PMID- 29178611 TI - Influence of Images on the Evaluation of Jams Using Conjoint Analysis Combined with Check-All-That-Apply (CATA) Questions. AB - A study of the influence of the use of images in a conjoint analysis combined with check-all-that apply (CATA) questions on jams was carried out. The relative importance of flavor and the information presented in the label in the willingness to purchase and the perception of how healthy the product is has been evaluated. Sixty consumers evaluated the stimuli presented only in text format (session 1), and another group of 60 consumers did so by receiving the stimuli in text format along with an image of the product (session 2). In addition, for each stimulus, consumers answered a CATA question consisting of 20 terms related to their involvement with the product. The perception of healthy increased when the texts were accompanied with images and also increased when the text included information. Willingness to purchase was only influenced by the flavor of the jams. The presence of images did not influence the CATA question's choice of terms, which were influenced by the information presented in the text. The use of a check-all-that-apply question in concepts provided an interesting possibility when they were combined with the results from the conjoint analysis, improving the comprehension of consumers' perception. Using CATA questions as an alternative way of evaluating consumer involvement seems to be beneficial and should be evaluated much further. PMID- 29178610 TI - Evidence of porcine circovirus-like virus P1 in piglets with an unusual congenital tremor. AB - Outbreaks of trembling and shaking were reported among pigs at two pig farms in Jiangsu Province, China. Serum and tissue samples tested positive for porcine circovirus-like virus P1 and negative for classical swine fever virus, porcine circovirus type 2, astrovirus and porcine pestivirus using PCR/RT-PCR and immunohistochemical techniques. High P1 viral genome loads were identified in sera, brain and lymph node tissue samples by qPCR. In addition, one of the most notable pathological changes was dissolution of the nucleus in Purkinje cells. The results of this study provide molecular evidence of an association between congenital tremor in pigs and P1 virus. PMID- 29178612 TI - Identification of a sugar gustatory receptor and its effect on fecundity of the brown planthopper Nilaparvata lugens. AB - In insects, the gustatory system plays a crucial role in multiple physiological behaviors, including feeding, toxin avoidance, courtship, mating and oviposition. Gustatory stimuli from the environment are recognized by gustatory receptors. To date, little is known about the function of gustatory receptors in agricultural pest insects. In this study, we cloned a sugar gustatory receptor gene, NlGr11, from the brown planthopper (BPH), Nilaparvata lugens (Stal), a serious pest of rice in Asia; we then identified its ligands, namely, fructose, galactose and arabinose, by calcium imaging assay. After injection of NlGr11 double-stranded RNA, we found that the number of eggs laid by BPH decreased. Moreover, we found that NlGr11 inhibited the phosphorylation of adenosine monophosphate-activated protein kinase (AMPK) and promoted the phosphorylation of protein kinase B (AKT). These findings demonstrated that NlGr11 could accelerate the fecundity of BPH through AMPK- and AKT-mediated signaling pathways. This is the first report to indicate that a gustatory receptor modulates the fecundity of insects and that the receptor could be a potential target for pest control. PMID- 29178613 TI - Aging mechanisms and intervention targets. AB - Premature aging occurs frequently to various tissues and organs resulting in the tissue-specific chronic diseases. The mechanisms of tissue-specific premature aging are largely unknown. In response to environmental cues, aging may originate from cytoplasm or the nucleus of a cell with cytoplasm aging in association with organelle degeneration in terminally differentiated cells and nuclear aging with dysfunctional telomeres and irreversible cell cycle arrest in stem and cancer cells. Either cytoplasm aging or nuclear aging may cause extracellular senescence associated low-grade inflammation to spread aging. Referring to the recent findings in this special issue of Healthy Aging in CEPP and beyond, we describe the molecular and cellular mechanisms of physiological aging and tissue-specific pathological aging in chronic diseases. PMID- 29178614 TI - Antibacterial activity of chitosan against Burkholderia pseudomallei. AB - The ability of Burkholderia pseudomallei to persist and survive in the environment is a health problem worldwide. Therefore, the antibacterial activities of chitosan against four environmental isolates of B. pseudomallei from soil in Khon Kaen, Thailand, were investigated. Antibacterial activities were assessed by a plate count technique after treatment with 0.2, 0.5, 1, 2 or 5 mg ml-1 chitosan for 0, 24 and 48 hr. Chitosan at 5 mg ml-1 completely killed all four B. pseudomallei isolates within 24 hr, whilst 2 mg ml-1 chitosan lowered the viability of B. pseudomallei by 20% within the same time span. Chitosan may act by disruption of the cell membrane, releasing intracellular components that can be detected spectrophotometrically at 260 and 280 nm. Transmission electron microscopy inspection of chitosan-treated B. pseudomallei revealed damage to the bacterial membranes. This study demonstrated the effective antibacterial activity by chitosan against B. pseudomallei. Chitosan causes disruption of the bacterial cell membrane, release of intracellular constituents and cell death. This study revealed the inhibitory potential of chitosan for mitigating B. pseudomallei occurrences. PMID- 29178615 TI - Plant organ senescence - regulation by manifold pathways. AB - Senescence is the final stage of plant ontogeny before death. Senescence may occur naturally because of age or may be induced by various endogenous and exogenous factors. Despite its destructive character, senescence is a precisely controlled process that follows a well-defined order. It is often inseparable from programmed cell death (PCD), and a correlation between these processes has been confirmed during the senescence of leaves and petals. Despite suggestions that senescence and PCD are two separate processes, with PCD occurring after senescence, cell death responsible for senescence is accompanied by numerous changes at the cytological, physiological and molecular levels, similar to other types of PCD. Independent of the plant organ analysed, these changes are focused on initiating the processes of cellular structural degradation via fluctuations in phytohormone levels and the activation of specific genes. Cellular structural degradation is genetically programmed and dependent on autophagy. Phytohormones/plant regulators are heavily involved in regulating the senescence of plant organs and can either promote [ethylene, abscisic acid (ABA), jasmonic acid (JA), and polyamines (PAs)] or inhibit [cytokinins (CKs)] this process. Auxins and carbohydrates have been assigned a dual role in the regulation of senescence, and can both inhibit and stimulate the senescence process. In this review, we introduce the basic pathways that regulate senescence in plants and identify mechanisms involved in controlling senescence in ephemeral plant organs. Moreover, we demonstrate a universal nature of this process in different plant organs; despite this process occurring in organs that have completely different functions, it is very similar. Progress in this area is providing opportunities to revisit how, when and which way senescence is coordinated or decoupled by plant regulators in different organs and will provide a powerful tool for plant physiology research. PMID- 29178616 TI - Diffusion-weighted MRI characteristics associated with prognostic pathological factors and recurrence risk in invasive ER+/HER2- breast cancers. AB - BACKGROUND: Hormone receptor-positive breast cancer is the most common subtype; better tools to identify which patients in this group would derive clear benefit from chemotherapy are needed. PURPOSE: To evaluate the prognostic potential of diffusion-weighted MRI (DWI) by investigating associations with pathologic biomarkers and a genomic assay for 10-year recurrence risk. STUDY TYPE: Retrospective. SUBJECTS: In all, 107 consecutive patients (from 2/2010 to 1/2013) with estrogen receptor (ER)-positive/HER2neu-negative invasive breast cancer who had the 21-gene recurrence score (RS) test (Oncotype DX, Genomic Health). FIELD STRENGTH/SEQUENCE: Each subject underwent presurgical 3T breast MRI, which included DWI (b = 0, 800 s/mm2 ). ASSESSMENT: Apparent diffusion coefficient (ADC) and contrast-to-noise ratio (CNR) were measured for each lesion by a fifth year radiology resident. Pathological markers (Nottingham histologic grade, Ki 67, RS) were determined from pathology reports. Medical records were reviewed to assess recurrence-free survival. STATISTICAL TESTS: RS was stratified into low (<18), moderate (18-30), and high (>30)-risk groups. Associations of DWI characteristics with pathologic biomarkers were evaluated by binary or ordinal logistic regression, as appropriate, with adjustment for multiple comparisons. Post-hoc comparisons between specific groups were also performed. RESULTS: ADCmean (odds ratio [OR] = 0.61 per 1 standard deviation [SD] increase, adj. P = 0.044) and CNR (OR = 1.76 per 1-SD increase, adj. P = 0.026) were significantly associated with increasing tumor grade. DWI CNR was also significantly associated with a high (Ki-67 >=14%) proliferation rate (OR = 2.55 per 1-SD increase, adj. P = 0.026). While there were no statistically significant linear associations in ADC (adj. P = 0.80-0.85) and CNR (adj. P = 0.56) across all three RS groups by ordinal logistic regression, post-hoc analyses suggested that high RS lesions exhibited lower ADCmean (P = 0.037) and ADCmax (P = 0.004) values and higher CNR (P = 0.008) compared to lesions with a low or moderate RS. DATA CONCLUSION: DWI characteristics correlated with tumor grade, proliferation index, and RS, and may potentially help to identify those with highest recurrence risk and most potential benefit from chemotherapy.

AB - The safety, pharmacokinetic, and pharmacodynamic effects of LY2584702, a selective inhibitor for p70 S6 serine/threonine protein kinase-1, were evaluated in healthy dyslipidemic volunteers. LY2584702 was tolerated well as a monotherapy and dose-dependently reduced low-density lipoprotein cholesterol and triglycerides by up to 60% and 50%, respectively, without significantly changing high-density lipoprotein cholesterol levels in plasma. LY2584702 also dose dependently decreased factor V activity. Alanine aminotransferase elevations were noted in 2 subjects when LY2584702 was given with atorvastatin. We suspect that the formation of 4-aminopyrazolo[3,4-d]pyrimidine (4-APP) during metabolism may have contributed to some of the adverse effects of LY2584702, and the contribution of 4-APP to the pharmacology merits further investigation. Although clinical investigation of LY2584702 has been terminated because of hepatotoxicity risk, we suggest that a selective inhibitor of p70 S6 serine/threonine protein kinase-1 with a larger margin of safety and without the possibility of being metabolized to 4-APP may be useful in the treatment of dyslipidemia. PMID- 29178618 TI - A unified partial likelihood approach for X-chromosome association on time-to event outcomes. AB - The expression of X-chromosome undergoes three possible biological processes: X chromosome inactivation (XCI), escape of the X-chromosome inactivation (XCI-E), and skewed X-chromosome inactivation (XCI-S). Although these expressions are included in various predesigned genetic variation chip platforms, the X chromosome has generally been excluded from the majority of genome-wide association studies analyses; this is most likely due to the lack of a standardized method in handling X-chromosomal genotype data. To analyze the X linked genetic association for time-to-event outcomes with the actual process unknown, we propose a unified approach of maximizing the partial likelihood over all of the potential biological processes. The proposed method can be used to infer the true biological process and derive unbiased estimates of the genetic association parameters. A partial likelihood ratio test statistic that has been proved asymptotically chi-square distributed can be used to assess the X chromosome genetic association. Furthermore, if the X-chromosome expression pertains to the XCI-S process, we can infer the correct skewed direction and magnitude of inactivation, which can elucidate significant findings regarding the genetic mechanism. A population-level model and a more general subject-level model have been developed to model the XCI-S process. Finite sample performance of this novel method is examined via extensive simulation studies. An application is illustrated with implementation of the method on a cancer genetic study with survival outcome. PMID- 29178619 TI - Abasic Site-Assisted Inhibition of Nicking Endonuclease Activity for the Sensitive Determination of Uracil DNA Glycosylase. AB - We herein describe A novel strategy to accurately determine uracil DNA glycosylase (UDG) activity is described based on the finding that nicking endonuclease-assisted cleavage reaction can be regulated by the presence of abasic site. This strategy utilizes DNA probes rationally designed to contain uracil base at the cleavage site for nicking endonuclease, which is coupled to the isothermal nicking endonuclease amplification reaction (NEAR) method. In the absence of UDG, intact DNA probes generate a large number of double-stranded (ds) DNA products through the NEAR, but the presence of UDG that converts uracil base into abasic site suppresses nicking endonuclease activity and the subsequent NEAR. As a result, dsDNA products are not produced, which is simply monitored by the dsDNA specific fluorescence dye, SYBR green I. By employing this strategy, we sensitively determined the UDG activity down to 0.003 U mL-1 with high specificity over other base excision enzymes. In addition, the diagnostic capability of this method was successfully verified by reliably assaying UDG present in a human serum sample. PMID- 29178620 TI - Comparative genomics of Spiraeoideae-infecting Erwinia amylovora strains provides novel insight to genetic diversity and identifies the genetic basis of a low virulence strain. AB - Erwinia amylovora is the causal agent of fire blight, one of the most devastating diseases of apple and pear. Erwinia amylovora is thought to have originated in North America and has now spread to at least 50 countries worldwide. An understanding of the diversity of the pathogen population and the transmission to different geographical regions is important for the future mitigation of this disease. In this research, we performed an expanded comparative genomic study of the Spiraeoideae-infecting (SI) E. amylovora population in North America and Europe. We discovered that, although still highly homogeneous, the genetic diversity of 30 E. amylovora genomes examined was about 30 times higher than previously determined. These isolates belong to four distinct clades, three of which display geographical clustering and one of which contains strains from various geographical locations ('Widely Prevalent' clade). Furthermore, we revealed that strains from the Widely Prevalent clade displayed a higher level of recombination with strains from a clade strictly from the eastern USA, which suggests that the Widely Prevalent clade probably originated from the eastern USA before it spread to other locations. Finally, we detected variations in virulence in the SI E. amylovora strains on immature pear, and identified the genetic basis of one of the low-virulence strains as being caused by a single nucleotide polymorphism in hfq, a gene encoding an important virulence regulator. Our results provide insights into the population structure, distribution and evolution of SI E. amylovora in North America and Europe.

PMID- 29178622 TI - Revisiting the functional anatomy of the palmaris longus as a thenar synergist. AB - Surgical studies describe the palmaris longus (PL) as a synergist in thumb abduction, which may facilitate its use in restoring thumb function using opponensplasty. However, beyond morphological descriptions and isometric thenar abduction strength measures, the evidence supporting the PL as a thenar synergist in-vivo is limited. The purpose here was to determine whether the PL provides synergistic contributions to thenar musculature by: (1) recording PL muscle activity using indwelling electromyography (EMG) during thumb movements; and (2) quantifying changes in PL muscle architecture using ultrasonography. In 10 healthy males, PL muscle activity was recorded during maximal thenar muscle contractions (abduction, flexion, opposition, adduction, and extension) with the wrist secured in a neutral position. The PL EMG was normalized to its maximal EMG recorded during isometric wrist flexion. Dynamic changes in PL muscle thickness (MT ) were determined during abduction and adduction using ultrasound imaging. The results indicate that the PL is activated during thenar movements with greatest relative PL EMG recorded during thenar abduction (46%), flexion (35%) and opposition (37%). Compared to rest, PL MT significantly increased (21%) during maximal thenar abduction. With direct measures in vivo, this study supports morphological and surgical observations indicating the PL acts as an extrinsic hand muscle in enhancing thenar muscle actions. Knowledge of the synergistic relationship between the PL and thenar musculature may allow for further development of surgical opponensplasty approaches using the abductor pollicis brevis and PL as a functional digastric unit.

AB - The unprecedented application of a chiral halogen-bonding [3]rotaxane host system for the discrimination of stereo- and E/Z geometric isomers of a dicarboxylate anion guest is described. Synthesised by a chloride anion templation strategy, the [3]rotaxane host recognises dicarboxylates through the formation of 1:1 stoichiometric sandwich complexes. This process was analysed by molecular dynamics simulations, which revealed the critical synergy of halogen and hydrogen bonding interactions in anion discrimination. In addition, the centrally located chiral (S)-BINOL motif of the [3]rotaxane axle component facilitates the complexed dicarboxylate species to be sensed via a fluorescence response. PMID- 29178624 TI - Clinical and genetic characteristics of xeroderma pigmentosum in Nepal. AB - BACKGROUND: Little is known about xeroderma pigmentosum (XP) in Himalayan countries. OBJECTIVE: To describe clinical characteristics of XP in Nepal and investigate its genetic bases. METHODS: This study was carried out on all consecutive patients referred for XP to a Nepalese tertiary referral centre in 2014-2015. Clinical data were collected using a standardized questionnaire. DNA was extracted from salivary samples, and next-generation sequencing (NGS) was conducted using a panel covering all 8 known XP genes (classical XP (XP-A to XP G) and XP variant) and a skin cancer modifier gene, the melanocortin 1 receptor gene (MC1R). RESULTS: Seventeen patients (median age: 15 years; range: 1-32) were included. Twelve had skin cancers (including a total of 8 squamous cell carcinomas, 60 basal cell carcinomas, ocular carcinomas requiring an orbital exenteration in 3 patients, but no melanoma). Fifteen patients carried the same homozygous non-sense XPC mutation c.1243C>T, p.R415X. A homozygous non-sense XPA mutation (p.W235X) was found in the only patient with a history of early severe sunburn reaction and associated neurological symptoms. Associated genetic alterations included heterozygous missense variants in XPD/ERCC2 gene and the presence of MC1R variant R163Q in 5 and 9 patients, respectively. CONCLUSION: Although not previously reported, XP seems frequent in Nepal. Patients often presented with a very severe phenotype after a long history of excessive sun exposure without knowledge of the disease. Fifteen of 17 had the same p.R415X XPC mutation, which seems very specific of XP in Nepal, suggesting a founder effect. NGS analyses frequently revealed associated genetic alterations which could play a modifier role in the clinical expression of the disease. PMID- 29178626 TI - Supramolecular Chirality Issues in Unorthodox Naphthalene Diimide Gelators. AB - Herein, the self-assembly of a few 1,3-dihydroxyl functionalized naphthalene diimide (NDI) derivatives has been reported with particular emphasis on the impact of chirality on gelation and the effect of self-assembly on charge-carrier mobility. A nonconventional gelator (R)-NDI, devoid of any long alkyl chains, exhibited spontaneous gelation in tetra-chloroethylene (TCE). Based on X-ray crystallography and powder X-ray diffraction studies, it was established that a ladder-like hydrogen-bonded chain formation between the 1,3-dihydroxyl group leads to the fibrillar structures with preferential helicity. Likewise the (S) isomer also exhibited identical gelation and mesoscopic structure but produced fibrils with the opposite handedness. Intriguingly, an equimolar mixture of the (R)- and (S)-isomers did not show any gelation ability, rather a macroscopic precipitation was observed and, in sharp contrast to the individual isomers, the morphology of the mixture showed ill-defined near spherical agglomerates. Differential scanning calorimetry (DSC) studies revealed an identical crystallization peak for the supramolecular polymer produced from the enantiopure gelators ((R)- or (S)-isomer), which was absent in their equimolar mixture. However, mixtures of the two isomers with enantiomeric excess retrieved the gelation ability and preferential helicity demonstrating that chiral amplification is operative in the present system through the so-called "majority rule" effect. Chirality induction was also realized by the "sergeant and soldier" principle in the supramolecular assembly of an achiral NDI gelator in the presence of either the (R)- or (S)-isomer as the chiral dopant. However, the strong helical bias induced by the chiral gelator was found to be opposite in nature compared to that found in the self-assembly of the pure chiral gelator that has been rarely reported in the literature. Flash-photolysis time-resolved microwave conductivity (FP-TRMC) measurements indicated the strong positive impact of the gelation on the electrical conductivity. PMID- 29178625 TI - Ileus Management International (IMAGINE): protocol for a multicentre, observational study of ileus after colorectal surgery. AB - AIM: The management of postoperative ileus following colorectal surgery remains controversial. It is the commonest complication after elective colorectal resection and is associated with an increased incidence of postoperative adverse events. The prevention and management of postoperative ileus remains unstandardized. This study aims to describe an international profile of gastrointestinal recovery after colorectal surgery and will assess the role of non-steroidal anti-inflammatory drugs, when used as postoperative analgesia, in expediting the return of gastrointestinal function. METHODS: A multicentre, student- and trainee-led, prospective cohort study will be conducted across both Europe and Australasia. Adult patients undergoing elective colorectal resection during 2-week data collection periods between January and April 2018 will be included. A site-specific questionnaire will capture compliance to Enhanced Recovery after Surgery components at participating centres. The primary outcome is time to gastrointestinal recovery, measured using a composite outcome of bowel function and oral tolerance. The impact of non-steroidal anti-inflammatory drugs on gastrointestinal recovery will be evaluated along with safety data with respect to anastomotic leak, acute kidney injury and complications within 30 days of surgery. DISCUSSION: This protocol describes the methodology of an international, observational assessment of gastrointestinal recovery after colorectal surgery. It discusses key challenges and describes how the results will impact on future investigation. The study will be conducted across a large student- and trainee-led collaborative network, with prospective quality assurance and data validation strategies. PMID- 29178627 TI - Cell extracts from spleen and adipose tissues restore function to irradiation injured salivary glands. AB - A cell extract from whole bone marrow (BM), which we named "BM Soup," has the property to restore saliva secretion to irradiation (IR)-injured salivary glands (SGs). However, BM cell harvesting remains an invasive procedure for the donor. The main objective of this study was to test the therapeutic effect of "Cell Soups" obtained from alternate tissues, such as adipose-derived stromal cells (ADSCs) and spleen cells to repair SGs. BM Soup, Spleen Soup, ADSC Soup, or saline (vehicle control) was injected intravenously into mice with IR-injured SGs (13Gy). Results demonstrated that all three cell soups restored 65-70% of saliva secretion, protected acinar cells, blood vessels, and parasympathetic nerves, and increased cell proliferation. Although protein array assays identified more angiogenesis-related growth factors in ADSC Soup, the length of its therapeutic efficiency on saliva flow was less than that of the BM Soup and Spleen Soup. Another objective of this study was to compare "Fresh" versus "Cryopreserved (-80 degrees C)" BM Soup. It was found that the therapeutic effect of 12-month "Cryopreserved BM Soup" was comparable to that of "Fresh BM Soup" on the functional restoration of IR-injured SGs. In conclusion, both Spleen Soup and ADSC Soup can be used to mitigate IR-damaged SGs.

AB - A multiresidue method was developed for the determination of 19 emerging organic contaminants (pharmaceutical drugs, personal care products, and bisphenol A) in poultry manure. Lyophilized samples of manure were extracted by ultrasound assisted matrix solid-phase dispersion and the extracts were analyzed by gas chromatography with tandem mass spectrometry after derivatization. Analysis of spiked poultry manure samples, at levels ranging from 25 to 150 ng/g, gave satisfactory recovery results for all the compounds, with values from 67 to 106%. The developed procedure provided detection limits that ranged from 0.9 to 2.2 ng/g. Finally, the validated method was applied to poultry manure samples collected from 23 poultry farms in Spain. Salicylic acid was found in most of the samples analyzed at levels up to 2501 ng/g, whereas, methyl paraben, orthophenylphenol, ibuprofen, paracetamol, and carbamazepine were detected at levels up to 250 ng/g. Composting of manure showed an important decrease in the levels of the detected contaminants.

AB - The present study was conducted to determine the difference in plasma prostaglandin F2 alpha metabolite concentrations following oxytocin (OT) challenge between pregnant and non-pregnant cows. Experiment 1: cows were subjected to the OT challenge test on days 12, 14 or 16 (day of estrus = day 0) with or without prior insemination and plasma 13,14-dihydro-15-keto prostaglandin F2 alpha (PGFM) concentrations were measured from -30 to 180 min after OT injection. On day 16, the increment of plasma PGFM concentrations in response to OT injection was significantly smaller in pregnant than that in cyclic cows. On days 12 and 14, there was little OT-induced PGFM secretion and no difference in PGFM increase between the pregnant and cyclic cows. Experiment 2: cows were inseminated on day 0 and subjected to the OT challenge test on day 16. Cows were classified into non-pregnant/early embryonic death (NP/EED), late embryonic death (LED) and pregnant (PREG) groups. The increment of PGFM concentrations in response to OT injection was less in both PREG and LED groups than that in the NP/EED group. In conclusion, plasma PGFM secretion induced by OT is suggested as the base of pregnancy diagnosis prior to returning estrus in cows. PMID- 29178634 TI - Two Distinct Substrate Binding Modes for the Normal and Reverse Prenylation of Hapalindoles by the Prenyltransferase AmbP3. AB - The cyanobacterial prenyltransferase AmbP3 catalyzes the reverse prenylation of the tetracyclic indole alkaloid hapalindole U at its C-2 position. Interestingly, AmbP3 also accepts hapalindole A, a halogenated C-10 epimer of hapalindole U, and catalyzes normal prenylation at its C-2 position. The comparison of the two ternary crystal structures, AmbP3-DMSPP/hapalindole U and AmbP3-DMSPP/hapalindole A, at 1.65-2.00 A resolution revealed two distinct orientations for the substrate binding that define reverse or normal prenylation. The tolerance of the enzyme for these altered orientations is attributed to the hydrophobicity of the substrate binding pocket and the plasticity of the amino acids surrounding the allyl group of the prenyl donor. This is the first study to provide the intimate structural basis for the normal and reverse prenylations catalyzed by a single enzyme, and it offers novel insight into the engineered biosynthesis of prenylated natural products. PMID- 29178633 TI - Norfloxacin salts of carboxylic acids curtail planktonic and biofilm mode of growth in ESKAPE pathogens. AB - AIMS: To enhance the antimicrobial and antibiofilm activity of norfloxacin against the planktonic and biofilm mode of growth in ESKAPE pathogens using chemically modified norfloxacin salts. METHODS AND RESULTS: Antimicrobial testing, synergy testing and time-kill curve analysis were performed to evaluate antibacterial effect of norfloxacin carboxylic acid salts against ESKAPE pathogens. In vivo efficacy to reduce bacterial bioburden was evaluated in zebrafish infection model. Crystal violet assay and live-dead staining were performed to discern antibiofilm effect. Membrane permeability, integrity and molecular docking studies were carried out to ascertain the mechanism of action. The carboxylic acid salts, relative to parent molecule norfloxacin, displayed two to fourfold reduction in minimum inhibitory concentration against Staphylococcus aureus and Pseudomonas aeruginosa, in addition to displaying potent bacteriostatic effect against certain members of ESKAPE pathogens. In vivo treatments revealed that norfloxacin tartrate (SRIN2) reduced MRSA bioburden by greater than 1 log fold relative to parent molecule in the muscle tissue. In silico docking with gyrA of S. aureus showed increased affinity of SRIN2 towards DNA gyrase. The enhanced antibacterial effect of norfloxacin salts could be partially accounted by altered membrane permeability in S. aureus and perturbed membrane integrity in P. aeruginosa. Antibiofilm studies revealed that SRIN2 (norfloxacin tartrate) and SRIN3 (norfloxacin benzoate) exerted potent antibiofilm effect particularly against Gram-negative ESKAPE pathogens. The impaired colonization of both S. aureus and P. aeruginosa due to improved norfloxacin salts was further supported by live-dead imaging. CONCLUSION: Norfloxacin carboxylic acid salts can act as potential alternatives in terms of drug resensitization and reuse. SIGNIFICANCE AND IMPACT OF THE STUDY: Our study shows that carboxylic acid salts of norfloxacin could be effectively employed to treat both planktonic- and biofilm-based infections caused by select members of ESKAPE pathogens. PMID- 29178635 TI - Effect of non-surgical weight management on weight and glycaemic control in people with type 2 diabetes: A comparison of interventional and non interventional outcomes at 3 years. AB - AIMS: To examine the long-term effectiveness of lifestyle weight management interventions, recommended in clinical guidelines for patients with type 2 diabetes mellitus (T2DM) and obesity. MATERIALS AND METHODS: Electronic health records were used to follow 23 208 patients with T2DM and obesity in Glasgow, UK, for up to 3 years between 2005 and 2014. Patients were stratified by referral to and attendance at a lifestyle weight management intervention, and by attainment of a target weight loss of >=5 kg over 7 to 9 sessions ("successful completers"). Outcomes were change in weight, glycated haemoglobin (HbA1c) and diabetes medications. RESULTS: A total of 3471 potentially eligible patients were referred to the service, and fewer than half of these attended (n = 1537). Of those who attended 7 to 9 sessions, >40% successfully completed and achieved 5-kg weight loss (334/808). Successful completers maintained greater weight loss (change at 3 years -8.03 kg; 95% confidence interval [CI] -9.44 to -6.62) than the non completers (-3.26 kg; 95% CI -4.01 to -2.51; P < .001) and those not referred to the service (-1.00 kg; 95% CI -1.15 to -0.85; P < .001). Successful completers were the only patient group who did not increase their use of diabetes medication and insulin over 3 years. In adjusted models, successful completers had a clinically significant reduction in HbA1c (-3.7 mmol/mol; 95% CI -5.82 to -1.51) after 3 years; P <= .001) compared with non-completers and unsuccessful completers. CONCLUSIONS: A real-life structured weight management intervention in patients with diabetes can reduce weight in the medium term, result in improved glycaemic control with fewer medications, and may be more effective than pharmacological alternatives. Challenges include getting a higher proportion of patients referred to and engaged with interventions. PMID- 29178636 TI - A novel splice site variant in CYP11A1 in trans with the p.E314K variant in a male patient with congenital adrenal insufficiency. AB - BACKGROUND: The CYP11A1 gene encodes the cytochrome P450 side-chain cleavage enzyme, which is essential for steroid formation. Recessive variants in this gene can lead to impairment of sexual differentiation caused by a complete or partial loss of steroid hormone production. The phenotypic spectrum in affected 46XY males may vary from surgically repairable defects including cryptorchidism and hypospadias to complete feminization of external gonads, accompanied by symptoms of adrenal dysfunction. METHODS: Whole-exome sequencing (WES) of a 12-year-old male proband and his parents was performed after a protracted diagnostic odyssey failed to uncover the cause of his primary adrenal insufficiency. Of note, the proband had early symptomatology and corrective surgery for hypospadias, raising suspicion for a disorder of steroidogenesis. RESULTS: WES identified compound heterozygous variants in CYP11A1 including a novel canonical splice site variant (c.425+1G>A) and a previously reported p.E314K variant, which were consistent with a diagnosis of congenital adrenal insufficiency with partial 46XY sex reversal. CONCLUSION: Congenital adrenal insufficiency with 46XY sex reversal is a rare disorder that is characterized by dysregulation of steroid hormone synthesis, leading to adrenal and gonadal dysfunction. In this report, we describe a patient with adrenal insufficiency, hypospadias, and skin hyperpigmentation who was found to have a novel c.425+1G>A variant in trans with the p.E314K variant in CYP11A1. We performed structural analyses to examine the effect of the p.E314K variant on protein function and show that it falls in the core of the protein may disrupt cholesterol binding in the active site.

AB - BACKGROUND: Elevated plasma and urine formiminoglutamic acid (FIGLU) levels are commonly indicative of formiminoglutamic aciduria (OMIM #229100), a poorly understood autosomal recessive disorder of histidine and folate metabolism, resulting from formiminotransferase-cyclodeaminase (FTCD) deficiency, a bifunctional enzyme encoded by FTCD. METHODS: In order to further understanding about the molecular alterations that contribute to FIGLU-uria, we sequenced FTCD in 20 individuals with putative FTCD deficiency and varying laboratory findings, including increased FIGLU excretion. RESULTS: Individuals tested had biallelic loss-of-function variants in protein-coding regions of FTCD. The FTCD allelic spectrum comprised of 12 distinct variants including 5 missense alterations that replace conserved amino acid residues (c.223A>C, c.266A>G, c.319T>C, c.430G>A, c.514G>T), an in-frame deletion (c.1373_1375delTGG), with the remaining alterations predicted to affect mRNA processing/stability. These included two frameshift variants (c.990dup, c.1366dup) and four nonsense variants (c.337C>T, c.451A>T, c.763C>T, c.1607T>A). CONCLUSION: We observed additional FTCD alleles leading to urinary FIGLU elevations, and thus, providing molecular evidence of FTCD deficiency in cases identified by newborn screening or clinical biochemical genetic laboratory testing. PMID- 29178638 TI - Living with a rare disorder: a systematic review of the qualitative literature. AB - BACKGROUND: Individuals with rare diseases may face challenges that are different from those experienced in more common medical conditions. A wide range of different rare conditions has resulted in a myriad of studies investigating the specificities of the diagnosis in focus. The shared psychological experiences of individuals with a rare condition, however, have not been reviewed systematically. METHODS: We performed a systematic review, including qualitative studies on adults, published between 2000 and 2016. Papers including more than one rare genetic or nongenetic diagnosis were included. Studies based on single diagnoses were excluded except for four specific conditions: hemophilia (bleeding disorder), phenylketonuria (metabolic disorder), Fabry disease (lysosomal storage disorder), and epidermolysis bullosa (skin disorder). RESULTS: The review identified 21 studies. Findings were synthesized and categorized according to three main themes: (1) Consequences of living with a rare disorder, (2) Social aspects of living with a rare disorder, and (3) Experiences with the health care system. Findings point to several unique challenges, such as the psychological, medical, and social consequences of a lack of knowledge about the condition in health care and social settings. CONCLUSION: The findings highlight the need for more research on the shared psychological and social impact of living with a rare diagnosis across conditions, in order to identify risk factors and inform clinical practice.

AB - BACKGROUND: High heterogeneity in the CFTR gene mutations disturbs the molecular diagnosis of cystic fibrosis (CF). In order to improve the diagnosis of CF in our country, the present study aims to define a panel of common CFTR gene mutations by sequencing 27 exons of the gene in Ecuadorian Cystic Fibrosis patients. METHODS: Forty-eight Ecuadorian individuals with suspected/confirmed CF diagnosis were included. Twenty-seven exons of CFTR gene were sequenced to find sequence variations. Prevalence of pathogenic variations were determined and compared with other countries' data. RESULTS: We found 70 sequence variations. Eight of these are CF-causing mutations: p.F508del, p.G85E, p.G330E, p.A455E, p.G970S, W1098X, R1162X, and N1303K. Also this study is the second report of p.H609R in Ecuadorian population. Mutation prevalence differences between Ecuadorian population and other Latin America countries were found. CONCLUSION: The panel of mutations suggested as an initial screening for the Ecuadorian population with cystic fibrosis should contain the mutations: p.F508del, p.G85E, p.G330E, p.A455E, p.G970S, W1098X, R1162X, and N1303K.

AB - BACKGROUND: Johanson-Blizzard syndrome (JBS, MIM #243800) is a very rare autosomal recessive disorder characterized by exocrine pancreatic insufficiency, nasal wing hypoplasia, hypodontia, and other abnormalities. JBS is caused by mutations of the UBR1 gene (MIM *605981), encoding a ubiquitin ligase of the N end rule pathway. METHODS: Molecular findings in a total of 65 unrelated patients with a clinical diagnosis of JBS who were previously screened for UBR1 mutations by Sanger sequencing were reviewed and cases lacking a disease-causing UBR1 mutation on either one or both alleles were included in this study. In order to discover mutations that are not detectable by Sanger sequencing, we designed a probe set for multiplex ligation-dependent probe amplification (MLPA) analysis of the UBR1 gene and analyzed the copy number status of all 47 UBR1 exons. RESULTS: Our previous studies using Sanger sequencing could detect mutations in 93.1% of 130 disease-associated UBR1 alleles. Six patients with a highly suggestive clinical diagnosis of JBS and unsolved genotype were included in this study. MLPA analysis detected six alleles harboring exon deletions/duplications, thereby raising the mutation detection rate in the entire cohort to 97.7% (127/130 alleles). CONCLUSION: We conclude that single or multi-exon deletions or duplications account for a substantial proportion of JBS-associated UBR1 mutations. PMID- 29178641 TI - Pediatric healthcare costs for patients with 22q11.2 deletion syndrome. AB - BACKGROUND: The 22q11.2 deletion syndrome is a variably expressed disorder that can include cardiac, palate, and other physical abnormalities, immunodeficiency, and hypocalcemia. Because of the extreme variability in phenotype, there has been no available estimate of the total medical expenditure associated with the average case. METHODS: We have developed a model to estimate the cost from the time of diagnosis to age 20. Costs were based on patients seen at a specialty center but also considered those components of care expected to have been provided by external healthcare facilities. Expense was based on billed medical charges extracted from the electronic medical billing system for all patients with a diagnosis of DiGeorge or velocardiofacial syndrome from 1993-2015. Expenditures included maternal prenatal care directly related to an affected pregnancy, molecular/cytogenetic diagnosis, consultations, surgery, and/or other treatment and management. Most mental health services (except inpatient), therapy related to cognitive, behavioral, speech, pharmacy, and nonmedical costs (special education, vocational, respite, lost earnings) were not included. RESULTS: Data were available for 642 patients with 50.7% diagnosed prenatally or in the first year of life. The average cost for a patient was $727,178. Costs were highest for patients ascertained prenatally ($2,599,955) or in the first year of life ($1,043,096), those with cardiac abnormalities or referred for cardiac evaluation ($751,535), and patients with low T-cell counts ($1,382,222). CONCLUSION: This study demonstrates that there are significant medical costs associated with 22q11.2 deletion syndrome. PMID- 29178642 TI - The genetic profile of Leber congenital amaurosis in an Australian cohort. AB - BACKGROUND: Leber congenital amaurosis (LCA) is a severe visual impairment responsible for infantile blindness, representing ~5% of all inherited retinal dystrophies. LCA encompasses a group of heterogeneous disorders, with 24 genes currently implicated in pathogenesis. Such clinical and genetic heterogeneity poses great challenges for treatment, with personalized therapies anticipated to be the best treatment candidates. Unraveling the individual genetic etiology of disease is a prerequisite for personalized therapies, and could identify potential treatment candidates, inform patient management, and discriminate syndromic forms of disease. METHODS: We have genetically analyzed 45 affected and 82 unaffected individuals from 34 unrelated LCA pedigrees using predominantly next-generation sequencing and Array CGH technology. RESULTS: We present the molecular findings for an Australian LCA cohort, sourced from the Australian Inherited Retinal Disease Registry & DNA Bank. CEP290 and GUCY2D mutations, each represent 19% of unrelated LCA cases, followed by NMNAT1 (12%). Genetic subtypes were consistent with other reports, and were resolved in 90% of this cohort. CONCLUSION: The high resolution rate achieved, equivalent to recent findings using whole exome/genome sequencing, reflects the progression from hypothesis (LCA Panel) to non-hypothesis (RD Panel) testing and, coupled with Array CGH analysis, is a highly effective first-tier test for LCA.

PMID- 29178643 TI - Role of WNT10A in failure of tooth development in humans and zebrafish. AB - BACKGROUND: Oligodontia is a severe form of tooth agenesis characterized by the absence of six or more permanent teeth. Oligodontia has complex etiology and variations in numerous genes have been suggested as causal for the condition. METHODS: We applied whole-exome sequencing (WES) to identify the cause of oligodontia in a 9-year-old girl missing 11 permanent teeth. Protein modeling and functional analysis in zebrafish were also performed to understand the impact of identified variants on the phenotype. RESULTS: We identified a novel compound heterozygous missense mutation in WNT10A (c.637G>A:p.Gly213Ser and c.1070C>T:p.Thr357Ile) as the likely cause of autosomal recessive oligodontia in the child. Affected residues are located in conserved regions and variants are predicted to be highly deleterious for potentially destabilizing the protein fold and inhibiting normal protein function. Functional studies in zebrafish embryos showed that wnt10a is expressed in the craniofacies at critical time points for tooth development, and that perturbations of wnt10a expression impaired normal tooth development and arrested tooth development at 5 days postfertilization (dpf). Furthermore, mRNA expression levels of additional tooth development genes were directly correlated with wnt10a expression; expression of msx1, dlx2b, eda, and axin2 was decreased upon wnt10a knockdown, and increased upon wnt10a overexpression. CONCLUSIONS: Our results reveal a novel compound heterozygous variant in WNT10A as pathogenic for oligodontia, and demonstrate that perturbations of wnt10a expression in zebrafish may directly and/or indirectly affect tooth development recapitulating the agenesis phenotype observed in humans. PMID- 29178645 TI - Inherited SHQ1 mutations impair interaction with NAP57/dyskerin, a major target in dyskeratosis congenita. AB - BACKGROUND: The inherited bone marrow failure syndrome dyskeratosis congenita (DC) is most frequently caused by mutations in DKC1 (MIM# 300126), the gene encoding NAP57 (aka dyskerin). The typically missense mutations modulate the interaction of NAP57 with its chaperone SHQ1, but no DC mutations have been identified in SHQ1 (MIM# 613663). Here, we report on two compound heterozygous mutations in SHQ1 in a patient with a severe neurological disorder including cerebellar degeneration. METHODS: The SHQ1 mutations were identified by patient exome sequencing. The impact of the mutations was assessed in pulldown assays with recombinant NAP57. RESULTS: The SHQ1 mutations were the only set of mutations consistent with an autosomal recessive mode of inheritance. The mutations map to the SHQ1-NAP57 interface and impair the interaction of the recombinant SHQ1 variants with NAP57. CONCLUSION: Intrauterine growth retardation and the neurological phenotype of the patient are reminiscent of the severe clinical variant of DC, the Hoyeraal-Hreidarsson syndrome (HH). Hence, SHQ1 screening may be warranted in patients with inherited bone marrow failure syndromes. PMID- 29178646 TI - Novel autosomal dominant TNNT1 mutation causing nemaline myopathy. AB - BACKGROUND: Nemaline myopathy (NEM) is one of the three major forms of congenital myopathy and is characterized by diffuse muscle weakness, hypotonia, respiratory insufficiency, and the presence of nemaline rod structures on muscle biopsy. Mutations in troponin T1 (TNNT1) is 1 of 10 genes known to cause NEM. To date, only homozygous nonsense mutations or compound heterozygous truncating or internal deletion mutations in TNNT1 gene have been identified in NEM. This extended family is of historical importance as some members were reported in the 1960s as initial evidence that NEM is a hereditary disorder. METHODS: Proband and extended family underwent Sanger sequencing for TNNT1. We performed RT-PCR and immunoblot on muscle to assess TNNT1 RNA expression and protein levels in proband and father. RESULTS: We report a novel heterozygous missense mutation of TNNT1 c.311A>T (p.E104V) that segregated in an autosomal dominant fashion in a large family residing in the United States. Extensive sequencing of the other known genes for NEM failed to identify any other mutant alleles. Muscle biopsies revealed a characteristic pattern of nemaline rods and severe myofiber hypotrophy that was almost entirely restricted to the type 1 fiber population. CONCLUSION: This novel mutation alters a residue that is highly conserved among vertebrates. This report highlights not only a family with autosomal dominant inheritance of NEM, but that this novel mutation likely acts via a dominant negative mechanism. PMID- 29178647 TI - Comprehensive analysis of mutations in the MEFV gene reveal that the location and not the substitution type determines symptom severity in FMF. AB - BACKGROUND: Familial Mediterranean Fever (FMF) is an autoinflammatory disorder caused by mutations in the MEFV gene. These mutations appear in different populations with different frequencies and their caused symptom severities vary from mild to moderate to severe depending on the mutation type. METHODS: In this study, we analyzed the mutations that have been reported in the MEFV gene from symptomatic FMF patients and compared their frequencies in different populations from the 1000 Genome and the Exome databases, using statistical clustering. We also analyzed the nucleotide and amino acid substitution patterns across the MEFV gene. RESULTS: We found 16 (8%) nonsynonymous mutations outside exon 10 that did not cluster with known disease-causing mutations (DCMs), due to their high frequencies in other populations. We also studied the substitution patterns for nucleotides and amino acids to determine the conserved and variable regions in the MEFV gene. In general more nonsynonymous substitutions were reported in exons 2, 3, and 10 from the FMF database (symptomatic FMF patients) compared to the 1000 Genome and the Exome databases. The same was true for amino acid (AA) substitutions where there were 1.5 times more radical (RAD) to conservative (CON) changes. However, when it came to AA substitutions exon 10 was quite conserved with a RAD/CON ratio of 0.9. In fact, we report that the most severe FMF symptoms are caused by conservative mutations in two highly conserved exon 10 regions. CONCLUSION: We found presumptive FMF-causing mutations that did not cluster with DCMs based on their allele frequencies. We also observed that the type of mutation is less likely to determine the severity of the FMF symptoms; rather it was the location of the mutations that was the determining factor. PMID- 29178648 TI - Panel-based whole exome sequencing identifies novel mutations in microphthalmia and anophthalmia patients showing complex Mendelian inheritance patterns. AB - BACKGROUND: Microphthalmia and anophthalmia (MA) are congenital eye abnormalities that show an extremely high clinical and genetic complexity. In this study, we evaluated the implementation of whole exome sequencing (WES) for the genetic analysis of MA patients. This approach was used to investigate three unrelated families in which previous single-gene analyses failed to identify the molecular cause. METHODS: A total of 47 genes previously associated with nonsyndromic MA were included in our panel. WES was performed in one affected patient from each family using the AmpliSeqTM Exome technology and the Ion ProtonTM platform. RESULTS: A novel heterozygous OTX2 missense mutation was identified in a patient showing bilateral anophthalmia who inherited the variant from a parent who was a carrier, but showed no sign of the condition. We also describe a new PAX6 missense variant in an autosomal-dominant pedigree affected by mild bilateral microphthalmia showing high intrafamiliar variability, with germline mosaicism determined to be the most plausible molecular cause of the disease. Finally, a heterozygous missense mutation in RBP4 was found to be responsible in an isolated case of bilateral complex microphthalmia. CONCLUSION: This study highlights that panel-based WES is a reliable and effective strategy for the genetic diagnosis of MA. Furthermore, using this technique, the mutational spectrum of these diseases was broadened, with novel variants identified in each of the OTX2, PAX6, and RBP4 genes. Moreover, we report new cases of reduced penetrance, mosaicism, and variable phenotypic expressivity associated with MA, further demonstrating the heterogeneity of such disorders.

PMID- 29178649 TI - The maternal uniparental disomy of chromosome 6 (upd(6)mat) "phenotype": result of placental trisomy 6 mosaicism? AB - BACKGROUND: Maternal uniparental disomy of chromosome 6 (upd(6)mat) is a rare finding and its clinical relevance is currently unclear. Based on clinical data from two new cases and patients from the literature, the pathogenetic significance of upd(6)mat is delineated. METHODS: Own cases were molecularly characterized for isodisomic uniparental regions on chromosome 6. For further cases with upd(6)mat, a literature search was conducted and genetic and clinical data were ascertained. RESULTS: Comparison of isodisomic regions between the new upd(6)mat cases and those from four reports did not reveal any common isodisomic region. Among the patients with available cytogenetic data, five had a normal karyotype in lymphocytes, whereas a trisomy 6 (mosaicism) was detected prenatally in four cases. A common clinical picture was not obvious in upd(6)mat, but intrauterine growth restriction (IUGR) and preterm delivery were frequent. CONCLUSION: A common upd(6)mat phenotype is not obvious, but placental dysfunction due to trisomy 6 mosaicism probably contributes to IUGR and preterm delivery. In fact, other clinical features observed in upd(6)mat patients might be caused by homozygosity of recessive mutations or by an undetected trisomy 6 cell line. Upd(6)mat itself is not associated with clinical features, and can rather be regarded as a biomarker. In case upd(6)mat is detected, the cause for the phenotype is identified indirectly, but the UPD is not the basic cause. PMID- 29178651 TI - Clinical verification of genetic results returned to research participants: findings from a Colon Cancer Family Registry. AB - BACKGROUND: The extent to which participants act to clinically verify research results is largely unknown. This study examined whether participants who received Lynch syndrome (LS)-related findings pursued researchers' recommendation to clinically verify results with testing performed by a CLIA-certified laboratory. METHODS: The Fred Hutchinson Cancer Research Center site of the multinational Colon Cancer Family Registry offered non-CLIA individual genetic research results to select registry participants (cases and their enrolled relatives) from 2011 to 2013. Participants who elected to receive results were counseled on the importance of verifying results at a CLIA-certified laboratory. Twenty-six (76.5%) of the 34 participants who received genetic results completed 2- and 12 month postdisclosure surveys; 42.3% of these (11/26) participated in a semistructured follow-up interview. RESULTS: Within 12 months of result disclosure, only 4 (15.4%) of 26 participants reported having verified their results in a CLIA-certified laboratory; of these four cases, all research and clinical results were concordant. Reasons for pursuing clinical verification included acting on the recommendation of the research team and informing future clinical care. Those who did not verify results cited lack of insurance coverage and limited perceived personal benefit of clinical verification as reasons for inaction. CONCLUSION: These findings suggest researchers will need to address barriers to seeking clinical verification in order to ensure that the intended benefits of returning genetic research results are realized. PMID- 29178652 TI - Mutations in fetal genes involved in innate immunity and host defense against microbes increase risk of preterm premature rupture of membranes (PPROM). AB - BACKGROUND: Twin studies have revealed a significant contribution of the fetal genome to risk of preterm birth. Preterm premature rupture of membranes (PPROM) is the leading identifiable cause of preterm delivery. Infection and inflammation of the fetal membranes is commonly found associated with PPROM. METHODS: We carried out whole exome sequencing (WES) of genomic DNA from neonates born of African-American mothers whose pregnancies were complicated by PPROM (76) or were normal term pregnancies (N = 43) to identify mutations in 35 candidate genes involved in innate immunity and host defenses against microbes. Targeted genotyping of mutations in the candidates discovered by WES was conducted on an additional 188 PPROM cases and 175 controls. RESULTS: We identified rare heterozygous nonsense and frameshift mutations in several of the candidate genes, including CARD6, CARD8, DEFB1, FUT2, MBL2, NLP10, NLRP12, and NOD2. We discovered that some mutations (CARD6, DEFB1, FUT2, MBL2, NLRP10, NOD2) were present only in PPROM cases. CONCLUSIONS: We conclude that rare damaging mutations in innate immunity and host defense genes, the majority being heterozygous, are more frequent in neonates born of pregnancies complicated by PPROM. These findings suggest that the risk of preterm birth in African-Americans may be conferred by mutations in multiple genes encoding proteins involved in dampening the innate immune response or protecting the host against microbial infection and microbial products. PMID- 29178653 TI - Compound heterozygous CASQ2 mutations and long-term course of catecholaminergic polymorphic ventricular tachycardia. AB - BACKGROUND: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a potentially lethal inherited cardiac disorder characterized by episodic ventricular tachycardia during adrenergic stimulation. It is associated with significant morbidity and mortality. Knowledge of the underlying genetic cause, pathogenesis, and the natural history of the disease remains incomplete. Approximately 50% of CPVT cases are caused by dominant mutations in the cardiac ryanodine receptor (RYR2) gene, <5% of cases are accounted for by recessive mutations in cardiac calsequestrin (CASQ2) or Triadin (TRDN). METHODS: We report a family with two CASQ2 gene mutations. A research-based next-generation sequencing (NGS) initiative was used in a patient with a severe CPVT phenotype and her clinically unaffected son. Reverse transcription polymerase chain reaction (RT-PCR) from platelet RNA was used to assess the consequences of predicted splice variants. RESULTS: NGS revealed that the proband carried a novel c.199C>T (p.Gln67*) mutation and a previously reported splice site mutation c.532+1G>A in CASQ2. Her son is a heterozygous carrier of the c.199C>T (p.Gln67*) mutation alone and the proband was compound heterozygous at CASQ2. RNA analysis demonstrated that the splice site mutation results in the retention of intron 3 with no full-length CASQ2 mRNA. CONCLUSION: This study describes a novel CPVT genotype and further characterizes the effect of a previously reported CASQ2 splice site mutation. The long-term follow-up of 23 years since first symptom provides additional insight into the natural history of CASQ2-associated CPVT. PMID- 29178655 TI - RYR1 causing distal myopathy. AB - BACKGROUND: Congenital myopathies due to ryanodine receptor (RYR1) mutations are increasingly identified and correlate with a wide range of phenotypes, most commonly that of malignant hyperthermia susceptibility and central cores on muscle biopsy with rare reports of distal muscle weakness, but in the setting of early onset global weakness. METHODS: We report a case of a patient presenting with childhood onset hand stiffness and adult onset progressive hand weakness and jaw contractures discovered to have two variants in the RYR1 gene. RESULTS: The patient manifested with distal upper limb weakness which progressed to involve the distal lower limb, proximal upper limb, as well as the face in addition to limited jaw opening. Creatine kinase was mildly elevated with EMG findings supporting a myopathy. Muscle biopsy showed features consistent with centronuclear myopathy. Whole exome sequencing revealed a novel heterozygous pathogenic variant in RYR1 (c.12315_12328delAGAAATCCAGTTCC, p.Glu4106Alafs*8), and a heterozygous missense variant (c.10648C>T, p.Arg3550Trp) of unknown significance in compound heterozygous state. CONCLUSION: We expand the spectrum of RYR1-related myopathy with the description of a novel phenotype in an adult patient presenting with hand weakness and suggest considering RYR1 analysis in the diagnosis of distal myopathies. PMID- 29178654 TI - Sickle cell trait knowledge and health literacy in caregivers who receive in person sickle cell trait education. AB - BACKGROUND: Despite universal screening that detects sickle cell trait (SCT) in infancy, only 16% of Americans with SCT know their status. To increase SCT status awareness, effective education for patients and their families is needed. The objective of this study was to assess caregivers' SCT knowledge before and after an in-person SCT education session. METHODS: A trained educator provides in person SCT education to caregivers of referred infants with SCT at Nationwide Children's Hospital. From August 2015 to July 2016, primarily English-speaking caregivers of infants with hemoglobin S-trait were recruited and completed a health literacy assessment and a SCT knowledge assessment (SCTKA) before and after receiving education. Caregivers repeated the SCTKA again after >=6 months, if they could be contacted. RESULTS: Thirty-eight (38.1%) percent of 113 caregivers had high SCTKA scores (>=75%) before education but 90.3% achieved high scores after education. Caregivers with low SCTKA scores after education had significantly lower health literacy (P = 0.029) and baseline SCTKA scores (P = 0.003) compared to those with higher scores after education. At >=6 months, caregivers' scores were significantly higher (P = 0.014) than baseline, but only 73.3% scored >=75%. CONCLUSION: Our results suggest that caregivers' baseline SCT knowledge is low, improves with in-person education but may decline with time. Caregivers who do not achieve high SCT knowledge after education had lower health literacy and baseline knowledge. Future studies should determine if adapting in person education to caregivers' health literacy and knowledge levels results in high and sustained SCT knowledge among all caregivers and more individuals who know their SCT status. PMID- 29178657 TI - Does obesity cause a distinct phenotype of hidradenitis suppurativa? PMID- 29178656 TI - Unique genetic background and outcome of non-Caucasian Japanese probands with arrhythmogenic right ventricular dysplasia/cardiomyopathy. AB - BACKGROUND: Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is an inherited cardiomyopathy mainly caused by desmosomal gene mutation. More than half of Caucasian probands have desmosomal mutations, which lead to earlier onset of ventricular arrhythmias. Among non-Caucasians, the genetic background of ARVD/C probands and its prognostic impact remain unclear. METHODS AND RESULTS: We genotyped 99 unrelated Japanese ARVD/C probands for plakophilin 2 (PKP2), desmoglein 2 (DSG2), desmoplakin (DSP), and desmocollin 2 (DSC2) between 2005 and 2014. Seventy-five probands who fulfilled "definite" category according to the 2010 Task Force Criteria (TFC) were enrolled and followed up for 6.4 years. Sixty four percent of probands had desmosomal mutations; DSG2 was predominant (48% of mutations) followed by PKP2 (38%). DSG2 mutations were almost missense, whereas over 90% of PKP2 mutations were truncating mutations. Lethal ventricular arrhythmias (VAs, sustained ventricular tachycardia/fibrillation) occurred in 57% of probands as the first manifestation and 71% at the end of follow-up. Five died during follow-up. Truncating mutation carriers exhibited earlier lethal VAs onset compared to missense mutation carriers or mutation negatives (age at onset 35 +/- 12, 49 +/- 16, and 50 +/- 19 years, respectively, P < 0.05 in each). Cox proportional hazard analysis revealed for the first time that, compared to mutation negatives, truncating mutation carriers had higher risk for lethal VAs, and especially for onset by their 40s, in an age-dependent manner (RR = 4.6, P < 0.01 by their 40s; RR = 2.9, P = 0.01 by their 50s). CONCLUSION: The genetic background of Japanese ARVD/C probands is distinct from that of Caucasian probands, leading to distinct prognosis. The most affected gene mutations in Japanese probands were missense mutations in DSG2 leading to modest outcome, whereas PKP2 truncating mutations were the second most and might be a strong marker for lethal VAs in non-Caucasian Japanese ARVD/C probands. PMID- 29178658 TI - High-Pressure-Induced Comminution and Recrystallization of CH3 NH3 PbBr3 Nanocrystals as Large Thin Nanoplates. AB - High pressure (HP) can drive the direct sintering of nanoparticle assemblies for Ag/Au, CdSe/PbS nanocrystals (NCs). Instead of direct sintering for the conventional nanocrystals, this study experimentally observes for the first time high-pressure-induced comminution and recrystallization of organic-inorganic hybrid perovskite nanocrystals into highly luminescent nanoplates with a shorter carrier lifetime. Such novel pressure response is attributed to the unique structural nature of hybrid perovskites under high pressure: during the drastic cubic-orthorhombic structural transformation at ~2 GPa, (301) the crystal plane fully occupied by organic molecules possesses a higher surface energy, triggering the comminution of nanocrystals into nanoslices along such crystal plane. Beyond bulk perovskites, in which pressure-induced modifications on crystal structures and functional properties will disappear after pressure release, the pressure formed variants, i.e., large (~100 nm) and thin (<10 nm) perovskite nanoplates, are retained and these exhibit simultaneous photoluminescence emission enhancing (a 15-fold enhancement in the photoluminescence) and carrier lifetime shortening (from ~18.3 +/- 0.8 to ~7.6 +/- 0.5 ns) after releasing of pressure from 11 GPa. This pressure-induced comminution of hybrid perovskite NCs and a subsequent amorphization-recrystallization treatment offer the possibilities of engineering the advanced hybrid perovskites with specific properties. PMID- 29178660 TI - Motion contrast in primary visual cortex: a direct comparison of single neuron and population encoding. AB - Features from outside the classical receptive field (CRF) can modulate the stimulus-driven activity of single cells in the primary visual cortex. This modulation, mediated by horizontal and feedback networks, has been extensively described as a variation of firing rate and is considered the basis of processing features as, for example, motion contrast. However, surround influences have also been identified in pairwise spiking or local field coherence. Yet, evidence about co-existence and integration of different neural signatures remains elusive. To compare multiple signatures, we recorded spiking and LFP activity evoked by stimuli exhibiting a motion contrast in the CRFs surround in anesthetized cat primary visual cortex. We chose natural-like scenes over gratings to avoid predominance of simple visual features, which could be easily represented by a rate code. We analyzed firing rates and phase-locking to low-gamma frequency in single cells and neuronal assemblies. Motion contrast was reflected in all measures but in semi-independent populations. Whereas activation of assemblies accompanied single neuron rates, their phase relations were modulated differently. Interestingly, only assembly phase relations mirrored the direction of movement of the surround and were selectively affected by thermal deactivation of visual interhemispheric connections. We argue that motion contrast can be reflected in complementary and superimposed neuronal signatures that can represent different surround features in independent neuronal populations.

METHODS: This randomized, single-blind trial allocated women 18 to 50 years old with 4 to 20 migraine days per month and a BMI = 25.0 49.9 kg/m2 to 16 weeks of BWL (n = 54), which targeted exercise and eating behaviors for weight loss, or to migraine education control (ME, n = 56), which delivered didactic instruction on migraine and treatments. Participants completed a 4-week smartphone headache diary at baseline, posttreatment (16-20 wk), and follow-up (32-36 wk). The primary outcome was posttreatment change in migraine days per month, analyzed via linear mixed effects models. RESULTS: Of 110 participants randomly assigned, 85 (78%) and 80 (73%) completed posttreatment and follow-up. Although the BWL group achieved greater weight loss (mean [95% CI] in kilograms) than the ME group at posttreatment (-3.8 [-2.5 to -5.0] vs. + 0.9 [ 0.4 to 2.2], P < 0.001) and follow-up (-3.2 [-2.0 to -4.5] vs. + 1.1 [-0.2 to 2.4], P < 0.001), there were no significant group (BWL vs. ME) differences (mean [95% CI]) in migraine days per month at posttreatment (-3.0 [-2.0 to -4.0] vs. 4.0 [-2.9 to -5.0], P = 0.185) or follow-up (-3.8 [-2.7 to -4.8] vs. -4.4 [-3.4 to -5.5], P = 0.378). CONCLUSIONS: Contrary to hypotheses, BWL and ME yielded similar, sustained reductions in migraine headaches. Future research should evaluate whether adding BWL to standard pharmacological and/or nonpharmacological migraine treatment approaches yields greater benefits.

AB - Recent studies have shown that expression levels of different alleles at the same HLA class I locus can vary dramatically, which might have a broad influence on human disease. However, precise quantification of the relative expression level of each HLA allele is challenging, because distinguishing different alleles on the same locus is difficult. Here, we developed a series of allele-specific, real time polymerase chain reaction assays for quantifying HLA class I allele mRNA in most Han individuals. The alleles of almost all heterozygous genotypes with a frequency higher than 0.5% in our population (78 alleles on HLA-A locus, 124 alleles on HLA-B locus, and 74 alleles on HLA-C locus) were specifically amplified. The specificity of the amplification was strictly validated by setting the corresponding negative control for each allele of each genotype. The amplification efficiency of each reaction was determined, and the slopes of the reactions were compared. This study provides a tool for detecting the comprehensive expression profile of HLA class I alleles and will be useful not only for the investigation of the molecular mechanism underlying HLA allele expression regulation but also for exploration of immunological mechanisms involving HLA expression in the fields of tumour immune evasion, viral infection, auto-immune disorders, and graft vs host disease after haematopoietic stem cell transplantation.

AB - Established in 2006, the Centre for Alcohol Policy Research (CAPR) is Australia's only research centre with a primary focus on alcohol policy. CAPR has four main areas of research: alcohol policy impacts; alcohol policy formation and regulatory processes involved in implementing alcohol policies; patterns and trends in drinking and alcohol problems in the population; and the influence of drinking norms, cultural practices and social contexts, particularly in interaction with alcohol policies. In this paper, we give examples of key publications in each area. During the past decade, the number of staff employed at CAPR has increased steadily and now hovers at approximately 10. CAPR has supported the development of independent researchers who collaborate on a number of international projects, such as the Alcohol's Harm to Others study which is now replicated in approximately 30 countries. CAPR receives core funding from the Foundation for Alcohol Research and Education, and staff have been highly successful in securing additional competitive research funding. In 2016, CAPR moved to a new institutional setting at La Trobe University and celebrated 10 years of operation. PMID- 29178663 TI - Ketamine for chronic non-cancer pain: A meta-analysis and trial sequential analysis of randomized controlled trials. AB - BACKGROUND: Ketamine has been suggested to be efficient in relieving chronic pain. However, there is inconsistency across studies investigating the effect of ketamine for chronic pain management. We aimed to perform a meta-analysis in order to assess the efficacy of this compound during chronic non-cancer pain conditions. METHODS: The study consisted in a meta-analysis of clinical trials comparing ketamine to a placebo during chronic non-cancer pain. The primary endpoint of this study was pain relief 4 weeks after the beginning of treatment. Secondary outcomes were: pain relief 1, 2, 8 and 12 weeks after the beginning of treatment and incidence of psychedelic manifestations. RESULTS: Six studies were included in this meta-analysis. Overall, 99 patients received ketamine and 96 received placebo. Ketamine did not decrease pain intensity at 4 weeks (MD (on a 0 to 10 scale) = -1.12 [-2.33, 0.09], GRADE evidence: very low). However, analysing studies with no high-risk bias found ketamine to decrease pain intensity at 4 weeks and increased the level of GRADE evidence to moderate. Trial sequential analysis confirmed the overall result and revealed the lack of power of this meta analysis. Ketamine also decreased pain intensity at all other evaluated points in time. Ketamine increased the incidence of psychedelic manifestations in comparison to placebo. CONCLUSION: Results of this meta-analysis found moderate evidence suggesting the efficacy of ketamine during chronic pain. Further studies are warranted to conclude about the effect of ketamine during chronic pain conditions and to determine optimal administration regimes of this agent during this condition. SIGNIFICANCE: Ketamine has been found interesting for managing chronic pain. We performed a meta-analysis aiming to confirm those results. Ketamine was found efficient in alleviating pain up to 12 weeks after the beginning of treatment. However, overall evidence favouring the use of this compound was very low. PMID- 29178664 TI - Environmental enrichment and drug value: a behavioral economic analysis in male rats. AB - Rats raised in an enriched condition (EC) show decreased stimulant self administration relative to rats reared in an isolated condition (IC). However, few studies have examined the behavioral mechanisms underlying this environment induced difference in self-administration. Because economic demand for drugs of abuse predicts addiction-like behavior in both humans and animals, we applied a behavioral economic analysis to cocaine self-administration data in EC and IC rats. During cocaine self-administration, the dose decreased across blocks of trials (0.75-0.003 mg/kg/inf), which allowed for a determination of demand intensity and demand elasticity. Demand intensity did not differ between EC and IC rats; however, cocaine was more elastic in EC rats relative to IC rats (i.e. EC rats were less willing to respond for cocaine as the unit price increased). When EC rats were placed in an isolated condition, demand elasticity decreased, whereas elasticity increased for IC rats placed in an enriched condition. Additionally, we applied behavioral economic analyses to previously published self-administration data and found that our results replicate past findings with cocaine and methylphenidate. To determine if differences in demand elasticity are specific to drug reinforcement, a separate group of rats was tested in sucrose or saccharin self-administration. Results showed that sucrose and saccharin were more elastic in EC rats relative to IC rats, and demand intensity was lower for saccharin in EC rats relative to IC rats. Overall, drug and nondrug reinforcers are more elastic in EC rats, which may account for the protective effects of environmental enrichment against stimulant self-administration. PMID- 29178665 TI - Early impairment of the full-field photopic negative response in patients with Stargardt disease and pathogenic variants of the ABCA4 gene. AB - BACKGROUND: To study the photopic negative response of the full-field photopic electroretinography (ERG) in Stargardt patients with pathogenic variants in the ABCA4 gene. METHODS: A retrospective analysis of 35 Stargardt patients with ABCA4 gene pathogenic variants, compared to normal age-matched controls. Patients were clinically followed at the Ophthalmology Department of Fondazione Policlinico Universitario A. Gemelli/Universita Cattolica del Sacro Cuore, Rome, Italy. RESULTS: The photopic negative response of the full-field photopic ERG was compromised in most Stargardt patients. In the presence of a normal B-wave, the amplitude ratio between the photopic negative response and the B-wave displayed a 97% accuracy in detecting diseased eyes (receiver operating characteristic curves). CONCLUSIONS: In Stargardt patients with ABCA4 pathogenic mutations, the photopic negative response of the full-field photopic ERG is a very sensitive disease read-out. Its inclusion in standard ERG analysis would be a no-cost addition of practical consequence in the follow-up of Stargardt disease. The early impairment of the photopic negative response suggests that inner retinal function might be affected in Stargardt disease earlier than previously acknowledged. PMID- 29178666 TI - Luminescent studies of binuclear ternary europium(III) pyridineoxide tetrazolate complexes containing bis-phosphine oxide as auxiliary co-ligands. AB - A new class of antenna chromophores so called 'tetrazolates' have not been explored much for lanthanide luminescencent complexes. However, we have already published several articles considering pyridineoxide tetrazolates as sensitizer with lanthanide ions. Although this class of antenna attracted much less attention because of its poor photoluminescence quantum yields (tris pyridineoxide tetrazolate europium complex = 13% in solution) we tried and successfully achieved to improve the photoluminescence quantum yields for this particular antenna molecule by replacing coordinated water from the inner coordination sphere of europium ion by introducing phosphine oxides as additional chromophore. In the present article the two bis-phosphine oxides attach two molecules of tris-pyridineoxide tetrazolate europium(III) complex which leads to the improvement of the overall molar absorption coefficients as well as photo physical properties of the complexes. We found more than two-fold increase (31% in solution) in photoluminescence quantum yield with one of the coordinated phosphine oxides comparing with that of tris-pyridineoxide tetrazolate europium(III) complex. PMID- 29178667 TI - Comprehensive review of post-organ transplant hematologic cancers. AB - A higher risk for a variety of cancers is among the major complications of posttransplantation immunosuppression. In this part of a continuing series on cancers posttransplantation, this review focuses on the hematologic cancers after solid organ transplantation. Posttransplantation lymphoproliferative disorders (PTLDs), which comprise the great majority of hematologic cancers, represent a spectrum of conditions that include, but are not limited to, the Hodgkin and non Hodgkin lymphomas. The oncogenic Epstein-Barr virus is a key pathogenic driver in many PTLD cases, through known and unknown mechanisms. The other hematologic cancers include leukemias and plasma cell neoplasms (multiple myeloma and plasmacytoma). Clinical features vary across malignancies and location. Preventive screening strategies have been attempted mainly for PTLDs. Treatments include the chemotherapy regimens for the specific cancers, but also include reduction of immunosuppression, rituximab, and other therapies. PMID- 29178668 TI - Pseudomonas aeruginosa biofilm hampers murine central wound healing by suppression of vascular epithelial growth factor. AB - Biofilm-infected wounds are clinically challenging. Vascular endothelial growth factor and host defence S100A8/A9 are crucial for wound healing but may be suppressed by biofilms. The natural course of Pseudomonas aeruginosa biofilm infection was compared in central and peripheral zones of burn-wounded, infection susceptible BALB/c mice, which display delayed wound closure compared to C3H/HeN mice. Wounds were evaluated histopathologically 4, 7 or 10 days post-infection. Photoplanimetry evaluated necrotic areas. P. aeruginosa biofilm suppressed vascular endothelial growth factor levels centrally in BALB/c wounds but increased peripheral levels 4-7 days post-infection. Central zones of the burn wound displayed lower levels of central vascular endothelial growth factor as observed 4 and 7 days post-infection in BALB/c mice compared to their C3H/HeN counterparts. Biofilm suppressed early, centrally located S100A8/A9 in BALB/c and centrally and peripherally later on in C3H/HeN wounds as compared to uninfected mice. Peripheral polymorphonuclear-dominated inflammation and larger necrosis were observed in BALB/c wounds. In conclusion, P. aeruginosa biofilm modulates wounds by suppressing central, but inducing peripheral, vascular endothelial growth factor levels and reducing host response in wounds of BALB/c mice. This suppression is detrimental to the resolution of biofilm-infected necrosis. PMID- 29178669 TI - Identification of polystyrene nanoparticle penetration across intact skin barrier as rare event at sites of focal particle aggregations. AB - The question whether nanoparticles can cross the skin barrier is highly debated. Even in intact skin rare events of deeper penetration have been reported, but technical limitations and possible artifacts require careful interpretation. In this study, horizontal scanning by 2-photon microscopy (2 PM) of full-thickness human skin samples placed in a lateral position yielded highly informative images for skin penetration studies of fluorescently tagged nanoparticles. Scanning of large fields of view allowed for detailed information on interfollicular and follicular penetration in tissue blocks without damaging the sample. Images in histomorphological correlation showed that 2P-excited fluorescence signals of fluorescently tagged 20 and 200 nm polystyrene nanoparticles preferentially accumulated in the stratum corneum (SC) and in the upper part of vellus hair follicles (HFs). Rare events of deeper penetration in the SC and in the infundibulum of vellus HFs were observed at sites of high focal particle aggregations. Wide-field 2 PM allows for imaging of nanoparticle penetration in large tissue blocks, whereas total internal reflection microscopy (TIRFM) enables selective detection of individual nanoparticles as well as clusters of nanoparticles in the SC and within the epidermal layer directly beneath the SC, thus confirming barrier crossing with high sensitivity.

PMID- 29178671 TI - Claudin may be a Potential Biomarker for Epithelial Barrier Dysfunction in Asthma. PMID- 29178672 TI - Glycolysis and the Hexosamine Biosynthetic Pathway as Novel Targets for Upper and Lower Airway Inflammation. AB - Glycolysis is a process that rapidly converts glucose to lactate to produce adenosine triphosphate (ATP) under anaerobic conditions and occurs in all eukaryotic and prokaryotic cells. On the other hand, the hexosamine biosynthetic pathway (HBP) converts glucose to intermediate products like UDP-N acetylglucosamine, which is critical for post-translational modifications of proteins, such as protein glycosylation. These 2 pathways are well known to contribute to glucose metabolism, but recent studies indicate modulation of these pathways can alter immune system function. In this review article, the authors present results suggesting how cellular metabolism, including glycolysis and the HBP, occurs in immune cells, and the immunologic significances of such activities. In addition, they provide a review of the literature on the effects of glycolysis and the HBP on various autoimmune, immunologic, and allergic diseases. Finally, the authors briefly introduce the results of their research on the immunologic effects of HBP supplementation (glucosamine) in animal models of allergic disease. PMID- 29178673 TI - Viral Infections and Associated Factors That Promote Acute Exacerbations of Asthma. AB - Despite asthma being the most common chronic childhood ailment, there is still much to learn about the disease. Early childhood infections with well-known or emerging viruses can lay the pathophysiologic framework for asthma development and exacerbation later in life, which may be due partly to alteration of the airway microbiome. Once asthma is established, acute exacerbations are usually associated with infections with respiratory viruses, such as rhinoviruses (RVs). Once again, there are bidirectional interactions between viruses and airway bacteria that appear to influence the severity of illness and the likelihood of exacerbation. Studies employing recent advances in viral and bacterial identification analytic techniques will clarify these new concepts and may provide the basis for new treatments or prevention or respiratory infection associated exacerbation. This paper is a review of the associations among respiratory viruses, bacteria, inflammatory mechanisms, and asthma exacerbation. PMID- 29178674 TI - A Retrospective Study of Clinical Response Predictors in Subcutaneous Allergen Immunotherapy With House Dust Mites for Allergic Rhinitis. AB - PURPOSE: House dust mites (HDM) are major allergens that cause allergic rhinitis (AR). Allergen-specific subcutaneous immunotherapy (SCIT) has been shown to be clinically beneficial in many clinical trials. Such trials, however, are not reflective of all patient populations. The aim of this study was to describe the efficacy and safety of SCIT in routine clinical practice in Korean adults with AR sensitized to HDM. METHODS: We reviewed medical records of 304 patients with AR treated at an allergy clinic of a tertiary hospital using SCIT with aluminum hydroxide-adsorbed allergen extract targeting HDM alone or with pollens for at least 1 year from 2000 to 2012. Patients with asthma were excluded. Rates of remission, defined as no further requirement of maintenance medication, over time were determined by means of life tables and extension of survival analysis. Specific immunoglobulin E (IgE) levels to HDM were categorized into 6 classes. RESULTS: The mean time until achieving remission was 4.9+/-0.1 years, and the cumulative incidence of remission from AR was 76.6%. Severe AR (odds ratio [OR], 0.40; 95% confidence interval [CI], 0.23-0.69; P=0.001), specific IgE levels to HDM >=17.5 kU/L (OR, 1.85; 95% CI, 1.01-3.37; P=0.045), and duration of immunotherapy >=3 years (OR, 7.37; 95% CI, 3.50-15.51; P<0.001) were identified as significant predictors of clinical remission during SCIT for patients with AR sensitized to HDM. Overall, 73 patients (24.0%) experienced adverse reactions to SCIT, and only 1 case of anaphylaxis (0.3%) developed. CONCLUSIONS: SCIT with HDM was found to be effective and safe for patients with AR. Specific IgE levels to HDM and a duration of SCIT >=3 years may be predictors of clinical responses to SCIT in AR patients. PMID- 29178675 TI - Alteration in Claudin-4 Contributes to Airway Inflammation and Responsiveness in Asthma. AB - PURPOSE: Claudin-4 has been reported to function as a paracellular sodium barrier and is one of the 3 major claudins expressed in lung alveolar epithelial cells. However, the possible role of claudin-4 in bronchial asthma has not yet been fully studied. In this study, we aimed to elucidate the role of claudin-4 in the pathogenesis of bronchial asthma. METHODS: We determined claudin-4 levels in blood from asthmatic patients. Moreover, using mice sensitized and challenged with OVA, as well as sensitized and challenged with saline, we investigated whether claudin-4 is involved in the pathogenesis of bronchial asthma. Der p1 induced the inflammatory cytokines in NHBE cells. RESULTS: We found that claudin 4 in blood from asthmatic patients was increased compared with that from healthy control subjects. Plasma claudin-4 levels were significantly higher in exacerbated patients than in control patients with bronchial asthma. The plasma claudin-4 level was correlated with eosinophils, total IgE, FEV1% pred, and FEV1/FVC. Moreover, lung tissues from the OVA-OVA mice showed significant increases in transcripts and proteins of claudin-4 as well as in TJ breaks and the densities of claudin-4 staining. When claudin-4 was knocked down by transfecting its siRNA, inflammatory cytokine expressions, which were induced by Der p1 treatment, were significantly increased. CONCLUSIONS: These findings thus raise the possibility that regulation of lung epithelial barrier proteins may constitute a therapeutic approach for asthma. PMID- 29178676 TI - Chinese Herbal Medicine to Treat Allergic Rhinitis: Evidence From a Meta Analysis. AB - PURPOSE: Chinese herbal medicine (CHM) has been widely used in China to treat allergic rhinitis (AR). However, several studies have produced conflicting data with regard to the efficacy of the medicine. Our aim was to perform a meta analysis of randomized clinical trials (RCTs) to evaluate the relative efficacy of CHM. METHODS: We systematically searched the PubMed, Medline, and Springer electronic databases up to March 2017 for RCTs comparing the efficacy of CHM versus placebo for the treatment of patients with AR. Total nasal symptoms and quality of life were assessed through pooling mean difference (MD) with its 95% confidence interval (CI). Moreover, sensitivity and subgroup analyses according to control design and quality of life assessment were performed to evaluate the source of heterogeneity. RESULTS: Eleven RCTs were enrolled in the meta-analysis. Assessment of overall heterogeneity indicated significant heterogeneity among the individual studies (I2=100%, P<0.00001), and thus ransomed effects model was used to pool data. CHM was found to significantly enhance quality of life compared with placebo (MD=-0.88, (95% CI: -1.55, -0.21); P=0.01). The symptom of itchy nose, sneezing or total nasal symptoms scores were not significantly improved after CHM treatment, although the improvement in itchy nose just failed to reach significance (MD=0.09, (95% CI: 0.00, 0.18); P=0.06). CONCLUSIONS: This study suggests that CHM appears to improve the quality of life of AR patients. However, these findings, as well as the findings for the effect of CHM on sneezing, total nasal symptoms, and the symptom of itchy nose, need to be substantiated in larger cohorts of AR patients by further well-designed studies. PMID- 29178677 TI - Respiratory Function and Symptoms Post Cold Air Exercise in Female High and Low Ventilation Sport Athletes. AB - PURPOSE: Cold weather exercise is common in many regions of the world; however, it is unclear whether respiratory function and symptom worsen progressively with colder air temperatures. Furthermore, it is unclear whether high-ventilation sport background exacerbates dysfunction and symptoms. METHODS: Seventeen active females (measure of the maximum volume of oxygen [VO(2max)]: 49.6+/-6.6 mL.kg 1.min-1) completed on different days in random order 5 blinded running trials at 0 degrees C, -5 degrees C, -10 degrees C, -15 degrees C, and -20 degrees C (humidity 40%) in an environmental chamber. Distance, heart rate, and rating of perceived exertion (RPE) were measured within each trial; forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), forced expiratory flow at 25%-75% (FEF25-75), and forced expiratory flow at 50% (FEF50) were measured pre- and post-test (3, 6, 10, 15, and 20 minutes). Respiratory symptoms and global effort were measured post-test spirometry. RESULTS: Mean decreases were found in FEV1 (4%-5% at 0 degrees C, -5 degrees C, -10 degrees C, and -15 degrees C; 7% at -20 degrees C). FEF25-75 and FEF50 decreased 7% and 11% at -15 degrees C and -20 degrees C, respectively. Post-exertion spirometry results were decreased most at 3 to 6 minutes, recovering back to baseline at 20 minutes. Respiratory symptoms and global effort significantly increased at -15 degrees C and -20 degrees C with decreased heart rate. High-ventilation sports decreased function more than low ventilation participants but had fewer symptoms. CONCLUSIONS: These results indicate that intense exercise at cold air temperatures up to -20 degrees C is achievable; however, greater effort along with transient acute bronchoconstriction and symptoms of cough after exercising in temperatures colder than -15 degrees C are likely. It is recommended that individuals cover their mouth and reduce exercise intensity to ameliorate the effects of cold weather exercise. PMID- 29178678 TI - beta2-Adrenoceptor Blockade Deteriorates Systemic Anaphylaxis by Enhancing Hyperpermeability in Anesthetized Mice. AB - PURPOSE: Patients treated with propranolol, a nonselective beta-adrenoceptor antagonist, develop severe anaphylaxis, but the mechanism remains unknown. We determined effects of beta1- and beta2-adrenoceptor antagonists on the anaphylaxis-induced increase in vascular permeability in mice. METHODS: In anesthetized ovalbumin-sensitized C57BL mice, mean arterial blood pressure (MBP) was measured, and Evans blue dye extravasation and hematocrit (Hct) were assessed at 20 minutes after antigen injection. The following pretreatment groups (n=7/group) were studied: (1) sensitized control (non-pretreatment), (2) propranolol, (3) the selective beta2-adrenoceptor antagonist ICI 118,551, (4) the selective beta1-adrenoceptor antagonist atenolol, (5) adrenalectomy, (6) the selective beta2-adrenoceptor agonist terbutaline, and (7) non-sensitized groups. RESULTS: The antigen injection decreased MBP, and increased Hct and vascular permeability in the kidney, lung, mesentery, and intestine, but not in the liver or spleen. Pretreatment with ICI 118,551, propranolol and adrenalectomy, but not atenolol, reduced the survival rate and augmented the increases in Hct and vascular permeability in the kidney, intestine, and lung as compared with the sensitized control group. Pretreatment with terbutaline abolished the antigen induced alterations. Plasma epinephrine levels were increased significantly in the sensitize control mice. CONCLUSIONS: Blockade of beta2-adrenoceptor can deteriorate systemic anaphylaxis by augmenting hyperpermeability-induced increase in plasma extravasation by inhibiting beneficial effects of epinephrine released from the adrenal glands in anesthetized mice. PMID- 29178679 TI - Detecting Allergens From Black Tiger Shrimp Penaeus monodon That Can Bind and Cross-link IgE by ELISA, Western Blot, and a Humanized Rat Basophilic Leukemia Reporter Cell Line RS-ATL8. AB - BACKGROUND: Black tiger shrimp Penaeus monodon is one of the common causes of shellfish allergy that is increasing worldwide. One of the important problems in the management of shellfish allergy is the lack of accurate diagnostic assay because the biological and immunological properties of allergens in black tiger shrimp have not been well characterized. This study aims to detect proteins with the ability to bind and cross-link immunoglobulin E (IgE) from black tiger shrimp by enzyme-linked immunosorbent assay (ELISA), Western blot, and a humanized rat basophilic leukemia reporter cell line RS-ATL8. METHODS: Sera from shrimp allergic subjects were subjected to ELISA and Western blots using raw or cooked shrimp extract as antigens. Pooled sera were used to sensitize the RS-ATL8 reporter cell line and cells were activated by shrimp extract. Eluted protein extracts separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) were tested on the RS-ATL8 cell line and subjected to mass spectrometry to identify potential candidate allergens. RESULTS: Allergic sera reacted stronger to raw shrimp extract than cooked shrimp extract (P=0.009). Western blot demonstrated that major IgE reactivity protein bands were at 32-39 kDa and 91-230 kDa in both raw and cooked shrimp extracts. The eluted protein bands at the molecular weight of 38 and 115 kDa from raw shrimp extract induced IgE cross-linking as assayed by the RS-ATL8 cell line. These protein bands were subjected to mass spectrometry for analysis. Ubiquitin-activating enzyme and crustacyanin were identified as potential candidate novel shrimp allergens. CONCLUSIONS: The RS-ATL8 reporter cell line can be used to identify potential new shrimp allergens that can functionally cross-link IgE and induce mast cell degranulation. PMID- 29178680 TI - T-Helper Type 2 Cells Direct Antigen-Induced Eosinophilic Skin Inflammation in Mice. AB - Eosinophilic inflammation in combination with immunoglobulin E (IgE) production is a characteristic feature of atopic dermatitis. Although activated T-helper type (Th) 2 cells play critical roles in the local accumulation and activation of eosinophils, whether they induce eosinophilic skin inflammation, independent of the IgE-mediated pathway has been unclear. To address the functional role of T cells in allergic skin diseases, we herein transferred Th1/Th2-differentiated or naive DO11.10 T cells into unprimed BALB/c mice. Ovalbumin-specific Th2 cells, as well as eosinophils, accumulated in the skin upon antigen challenge, despite the absence of antigen-specific IgE. Neither antigen-specific Th1 nor naive T cells induced eosinophil accumulation, although Th1 cells by themselves migrated into the skin. Interleukin (IL)-4, IL-5, and eotaxin were specifically produced in the skin of antigen-challenged, Th2 cell-transferred mice, whereas interferon (IFN) gamma and regulated on activation, normal T cell expressed and secreted (RANTES) were preferentially produced in Th1 cells-transferred mice. Production of monocyte chemoattractant protein (MCP)-1 and MCP-3 was enhanced by both Th1 and Th2 cells. The accumulation of eosinophils and Th2 cells in the skin was suppressed by both dexamethasone and FK506, indicating an essential role of Th2 cells in eosinophil recruitment. We conclude that Th2 cells can induce eosinophilic infiltration into the skin in the absence of antigen-specific IgE. PMID- 29178681 TI - Clinical Course of Chronic Spontaneous Urticaria in the Korean Adult Population. AB - Knowledge of the clinical course of chronic spontaneous urticaria (CSU) remains unclear. The purpose of our study was to investigate the clinical course of CSU in the Korean adult population. Each patient in the CSU group who was defined by disease codes between 2003 and 2007 was tracked whether he or she went into remission or not until 2013. Kaplan-Meier survival analysis was carried out to analyze remission, and log-rank tests were performed for between-group comparisons. Demographic differences between subjects who went into remission 1 year after the initial diagnosis and those who did not were analyzed using chi2 tests. A total of 13,969 subjects were included in the CSU group. The 1-, 2-, 3-, 4-, and 5-year remission rates of CSU were 21.5%, 33.0%, 38.9%, 42.6%, and 44.6%, respectively. The proportion of subjects in the 65+ age group (P=0.050) and with male gender (P=0.002) was significantly higher among subjects who did not go into remission 1 year after the initial diagnosis. Our study indicates that CSU could have a more persistent course than previously reported. PMID- 29178683 TI - Reducing Anticholinergic Medication Burden in Patients With Psychotic or Bipolar Disorders. AB - OBJECTIVE: Anticholinergic medications are prescribed to treat extrapyramidal side effects (EPS) associated with antipsychotics. Anticholinergic medications cause several side effects and can often be withdrawn during the maintenance phase of antipsychotic treatment without EPS reemergence. The purpose of this quality improvement (QI) project was to reduce anticholinergic medication burden and improve quality of life in patients with severe mental illness. METHODS: Patients with DSM-IV-TR-diagnosed schizophrenia, schizoaffective disorder, and bipolar disorders in an outpatient psychiatric clinic who were prescribed benztropine were identified, screened for anticholinergic side effects by the treating psychiatrist, and referred to an on-site clinical pharmacist for a comprehensive medication review. Anticholinergic side effects, cognitive impairment, and impact on quality of life were assessed using a Likert scale. Recommendations for potential medication changes were discussed with the prescriber. Initial and follow-up assessments were conducted over 1-8 months to identify improvements in side effects and quality of life. RESULTS: Twenty-nine patients were assessed from November 2014 to December 2015. Patients were receiving from 1 to 6 medications with anticholinergic properties (median = 3 medications). Of the 29 patients, 19 were recommended for a medication change, with 13 having 1 or more anticholinergic medications discontinued and 6 having the dose decreased. A significant reduction in anticholinergic side effects and improvements in memory and quality of life were observed for these patients (P <= .05). CONCLUSIONS: In this interdisciplinary, collaborative QI project, patients whose anticholinergic burden was reduced experienced a significant improvement in side effects, memory, and quality of life. PMID- 29178682 TI - Real-Life Clinical Use of Symbicort(r) Maintenance and Reliever Therapy for Asthmatic Patients in Korea. AB - The aim of this study was to examine the daily practice patterns of Symbicort(r) Maintenance and Reliever Therapy (SMART) in Korean asthmatic patients and to analyze clinical signs related to overuse. This study used an observational, multicenter, noninterventional, prospective, uncontrolled design for examining asthmatic patients prescribed SMART to assess the frequency and pattern of Symbicort(r) usage as a maintenance and reliever medication. The characteristics of patients showing signs of overuse (frequency of inhalation: 8 or more times per day) were also analyzed. Among the 1,518 patients analyzed, 1,292 (85.1%) completed the trial. The number of mean inhalations per day was 2.14+/-1.15; the number of patients who had at least 1 as needed usage (PRN) inhalation per day was 843 (55.5%); the mean frequency of PRN use was 0.25+/-0.67 inhalations per day. The number of patients who overused for at least 1 day was 260 (17.1%). In particular, young patients, patients with limited physical activity, and patients with nocturnal symptoms demonstrated high frequency of overuse. The frequency of overuse during SMART was not high in Korean asthmatic patients and the asthma status of follow-up outpatients improved overall. However, there is a need for careful education targeted toward younger patients, patients with limited physical activity, and patients with nocturnal symptoms owing to their tendency to frequently overuse. PMID- 29178685 TI - Clinical and Genetic Predictors of Delayed Remission After Multiple Levels of Antidepressant Treatment: Toward Early Identification of Depressed Individuals for Advanced Care Options. AB - OBJECTIVE: To identify clinical and genetic characteristics that can be used to recognize depressed patients who are likely to respond quickly versus those who will have a more delayed response following multiple treatment trials. METHODS: The data used were obtained from the National Institute of Mental Health sponsored Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study, which was conducted between July 2001 and September 2006. Of the 4,041 treatment naive participants in the original study, 1,953 with DNA samples were included. Major depressive disorder (DSM-IV criteria) was defined as baseline score > 14 on the 17-item Hamilton Depression Rating Scale. Time to remission was defined from the entry point to when a score <= 5 on the Quick Inventory of Depressive Symptomatology, Clinician Rating was achieved, irrespective of the type or number of treatments received. A Kaplan-Meier estimator was used for data description, proportional hazard regression for model building, and logistic regression for measures of predictive accuracy. RESULTS: The overall rate of remission across all levels of treatment was 65.6%, and the overall median (interquartile range) of time to remission was 11.4 (6.0-17.9) weeks. The predictors of delayed remission included unemployment (P = .004), severe medical comorbidity (P < .0001), severe baseline depression (P < .0001), more than 4 dysthymic symptoms (P = .005), more than 9 posttraumatic stress symptoms (P = .005), and serotonin receptor 1A (P = .006) and cytochrome P450 2D6 (P = .002 for C/T and P = .0004 for T/T) genetic variants. The final model had good predictive measures of accuracy of area under the curve (70%) and sensitivity (88%). CONCLUSIONS: The results offer clinical tools for clinicians to identify depressed individuals who are likely to have delayed remission with multiple antidepressant treatments and therefore might be candidates for advanced care options. PMID- 29178686 TI - Memantine as an Augmentation Treatment for Schizophrenia: Limitations of Meta Analysis for Evidence-Based Evaluation of Research. AB - The action of memantine on N-methyl-D-aspartate (NMDA) glutamatergic receptors and the other pharmacodynamic actions of this drug suggest that it may benefit patients with schizophrenia. Many randomized controlled trials (RCTs) have examined this possibility. These RCTs have been meta-analyzed by at least 2 groups of authors. In one meta-analysis (8 RCTs, pooled N = 448), memantine (20 mg/d for 6-12 weeks) augmentation of antipsychotic drug therapy was found to attenuate the severity of negative symptoms and improve cognitive functioning; in both regards, the effect was large. Memantine was also associated with a small but statistically significant reduction in general psychopathology. Whereas memantine did not significantly attenuate positive symptom, depression, total psychopathology, and global illness ratings, it was also not associated with an increased risk of individual adverse events, discontinuation due to adverse events, or all-cause discontinuation. The findings of the other meta-analysis, which examined much the same body of literature, were largely similar. On the surface, these results suggest that memantine may be considered for the reduction of negative symptoms and cognitive impairment in schizophrenia. However, an examination of the individual RCTs and a careful look at the findings of the meta analyses identify so many important concerns that it is probably premature to draw conclusions about the usefulness of memantine as an augmentation strategy in schizophrenia. At best, it may be stated that there is a signal that supports the study of memantine in schizophrenia patients who are specifically impaired by negative symptoms and cognitive complaints. This is a good example of a situation in which meta-analysis did not provide a trustable evidence-based interpretation of literature. PMID- 29178684 TI - A Supervised Exercise Intervention for Youth at Risk for Psychosis: An Open-Label Pilot Study. AB - OBJECTIVE: A rapidly accumulating body of research suggests that exercise can improve symptoms and well-being in patients suffering from psychosis. Exercise may also promote neurogenesis in the hippocampus, a structure that plays an important role in the pathophysiology of psychosis. To date, there has not been an intervention focused on exercise prior to the onset of psychosis, a critical time for prevention of more serious illness. METHODS: In this pilot study, 12 young adults at ultrahigh risk (UHR) for psychosis were enrolled in a 12-week open-label exercise intervention. Participants were randomly assigned to exercise 2 or 3 times each week and exercised between 65% and 85% of maximum oxygen capacity (Vo2max) for 30 minutes each session under the supervision of an exercise physiologist. Positive and negative symptoms, social and role functioning, performance on neurocognitive tests, cardiovascular fitness, and hippocampal structure and functional connectivity were evaluated before and after the trial. RESULTS: A total of 9 participants completed the exercise intervention. Participants showed improved positive and negative symptoms and social and role functioning; improvement in multiple areas of cognition; and increased functional connectivity between the left hippocampus and occipital cortex after 12 weeks of exercise. CONCLUSIONS: The results of this study suggest that exercise interventions are feasible in a UHR sample and may promote improvement in clinical, social, and cognitive domains as well as changes to brain function in regions impacted by the development of psychosis. These findings set the stage for an ongoing phase 2 randomized controlled trial. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02155699. PMID- 29178687 TI - ? PMID- 29178688 TI - ?

AB - INTRODUCTION: The aim of this study is (1) to describe the characteristics of the organ harvesting activity conducted in 2012 at the Erasme's Hospital, Brussels University Hospital, (2) to highlight the different combinations " type of donor/types of organ's retrieved " in relation to organ harvestings carried out within the hospital, and (3) to calculate the organ harvesting's cost of acts. METHODS: The study is conducted according to the hospital perspective. It assesses the consumption of medical and nursing staff resources, disposable material costs, medical device costs, drugs costs, sterile instruments and biomedical equipment costs, of the 34 organ harvesting procedures that has been conducted this year. Costs are calculated by procedure, by donor's type, by organ and by combinations. RESULTS: Total cost is 99.442 ?, with an average cost per donor of 3.016 ?, 3.292 ? for DBD postmortem donor (Donor Brain Death) and 2.456 ? for DCD type (Donor Cardio-Circulatory Death). The average cost per organ leading to a transplantation is 1.842 ? for DCD type and 1.297 ? for DBD. CONCLUSION: The results show that there is as many costs as the number of organ harvesting's combinations. Integrate the revenue generated by organ harvestings could establish whether funding sources cover the costs generated by this activity or if a reform of the nomenclature should be considered. PMID- 29178691 TI - [Analysis of positive margins risk factors and long term recurrence in the conservative treatment of breast cancer]. AB - INTRODUCTION: breast conserving therapy remains the first choice in breast cancer care for the early stages. Adequate surgical margins are essential to reduce the risk of locoregional recurrence. This study aims to identify risk factors of positive margins and locoregional recurrence. MATERIALS AND METHODS: 437 patients who underwent a lumpectomy for invasive breast carcinoma or ductal carcinoma in situ have been included. Age, surgical margins, size, type, grade and number of tumor foci, the presence of ductal carcinoma in situ, lymph node status, expression of hormone receptors and HER-2 gene were assessed as risk factors for positive margins and locoregional recurrence. RESULTS: The disease-free survival is 94 % at 10 years. Patients with positive margins have lower survival (92 %) than those with negative margins (96 %) (p L 0.05). Lobular and multifocal tumors are at risk of positive margins. Tumors with positive margins, T2, grade III, triple negative and HER-2 positive neoplasms are at risk of locoregional recurrence while the expression of hormone receptors is a protective factor for local recurrence. CONCLUSION: It appears in our study that invasive lobular and multifocal tumors may present positive surgical margins. Studies on pre- operative work-up are needed. Biological factors of the tumor seem to play a fundamental role in the locoregional recurrence or persistence of the tumor. PMID- 29178692 TI - [Management of vaccination in children receiving an allogeneic marrow transplant]. AB - Over the last decades, significant advances in the diagnosis and therapeutics have considerably improved success rate from bone marrow transplant in patients suffering from otherwise life-threatening diseases, allowing now for prolonged survival and better quality of life after an allograft. However, infectious diseases remain one of the most serious complication in this population, hence associated with a high morbidity and mortality. Prevention, in particular through vaccination, constitutes a cornerstone of the management of immunocompromised hosts, since this procedure aims to protect them once back to life in community after long periods of hospitalization. If the necessity of vaccinating immunocompromised patients as well as their family is unequivocally recognized among health care workers, some questions remain source of debate. Several famous societies edited guidelines, but those differ from each other and cannot be transposed from a country to another without considering their local epidemiology and implemented vaccination schedule. Moreover, development and availability of new vaccines render recommendations constantly susceptible to adaptations. After exhaustive literature review, this article aims to offer pragmatic answers to the main questions raised by healthcare workers when vaccinating children after a bone marrow transplant. We here review all vaccines available and discuss their modalities of administration considering the timing after transplant, the immunological residual status and the medical history of the child. We also offer clues to optimize vaccination of patients' siblings. In addition to highlight some interrogations about future vaccines formulations, we propose here a vaccination schedule tailored for pediatric bone marrow transplant recipients in Belgium in 2017.

AB - Fixed drug eruption is an erythematous eruption of one or more centimetric rounded or oval lesions well demarcated, recurrent at the same place and leaving a residual purple pigmentation. Diagnosis is clinical. Skin biopsy is not essential except in doubtful cases (eg bullous drug eruption can simulate Lyell Syndrome or mucosal reminiscent of erythema multiforme). The etiology is almost always drug-induced; rare cases of toxic or food issue were reported. Histopathology is immuno-allergic; recurrences correspond to re-exposure to allergen. There is no specific treatment except stopping the causing drug. PMID- 29178694 TI - ? PMID- 29178695 TI - ?

Erasmus was in close contact with the medical world. Indeed, he suffered all his life from more or less severe diseases and had therefore frequent contacts with doctors. Also, the ideas he was defending stood for the principle of free inquiry before its time. For these various reasons giving the name " Erasmus " to the university clinics of the Free University of Brussels (ULB) was a judicious choise. PMID- 29178697 TI - Complex signal-based optical coherence tomography angiography enables in vivo visualization of choriocapillaris in human choroid. AB - The choriocapillaris (CC) plays an essential role in maintaining the normal functions of the human eye. There is increasing interest in the community to develop an imaging technique for visualizing the CC, yet this remains underexplored due to technical limitations. We propose an approach for the visualization of the CC in humans via a complex signal-based optical microangiography (OMAG) algorithm, based on commercially available spectral domain optical coherence tomography (SD-OCT). We show that the complex signal based OMAG was superior to both the phase and amplitude signal-based approaches in detailing the vascular lobules previously seen with histological analysis. With this improved ability to visualize the lobular vascular networks, it is possible to identify the feeding arterioles and draining venules around the lobules, which is important in understanding the role of the CC in the pathogenesis of ocular diseases. With built-in FastTracTM and montage scanning capabilities, we also demonstrate wide-field SD-OCT angiograms of the CC with a field of view at 9*11 mm2. PMID- 29178698 TI - Effects of riboflavin, calcium-phosphate layer and adhesive system on stress strain behavior of demineralized dentin. AB - PURPOSE: To evaluate if three dentin treatments improved mechanical properties of demineralized dentin. METHODS: Dentin slices were demineralized and treated with a universal adhesive, Scotchbond Universal (SBU), a cross-linker, Riboflavin (RF), and a calcium phosphate-based product, Teethmate (TM). The groups (n= 8 per group) were: Group 1: SBU, Group 2: RF + SBU, Group 3: RF + TM + SBU. Tensile tests were performed; stress/strain curves and E modulus were calculated. Differences between groups were assessed by one-way ANOVA and Duncan post hoc test. RESULTS: At high strains, no significant differences in E moduli were observed between dentin specimens treated only with SBU and those treated with RF + SBU. A significantly higher E modulus was observed in dentin specimens treated with RF + TM + SBU. In the presence of an adhesive system, crosslinking collagen with RF and TM addition significantly improved mechanical properties of dentin. CLINICAL SIGNIFICANCE: Restitution of mineral content into dentin, in addition to collagen strengthening, may significantly improve mechanical properties of previously demineralized dentin, when covered by an adhesive system in a reasonable clinical timeframe. PMID- 29178699 TI - Differences in physical characteristics and sealing ability of three tricalcium silicate-based cements used as root-end-filling materials. AB - PURPOSE: To evaluate differences in physical characteristics and sealing ability of root-end-fillings made with these materials compared to the gold standard (ProRoot MTA). METHODS: The physical characteristics of ProRoot MTA, Medcem MTA and Biodentine were evaluated regarding setting time, flow, film thickness, solubility and radiopacity according to the German Institute for Standardization (EN-ISO 6878). To investigate their sealing ability as root-end-fillings, a glucose penetration model was used. 60 human extracted single-rooted teeth were endodontically treated, root-end resections performed and divided in three groups of 20 teeth, using either ProRoot MTA, Medcem MTA or Biodentine as root-end filling material. After 30 days, glucose concentrations were determined photometrically, followed by statistical analysis (Kruskal-Wallis test, Mann Whitney U-test). RESULTS: Biodentine showed the fastest setting time (< 12 minutes) and lowest film thickness (0.11+/- 0.01 mm), whereas Medcem MTA showed the best values regarding solubility (< 0.1%) and flow (9.5+/- 0.02 mm). ProRoot MTA revealed the highest radiopacity (7.58+/- 0.1 mm aluminum equivalent). The glucose leakage in the Medcem MTA group was significantly lower than in the ProRoot MTA group (P= 0.011). Biodentine showed lower leakage than ProRoot MTA (P= 0.031). CLINICAL SIGNIFICANCE: As Medcem MTA showed significantly lower leakage than the other materials tested, it may be an alternative for root-end fillings with comparable physical characteristics to the current gold standard. With the exception of the high solubility, Biodentine performed well regarding leakage and setting time. PMID- 29178700 TI - Comparison of different maintenance strategies within supportive implant therapy for prevention of peri-implant inflammation during the first year after implant restoration. A randomized, dental hygiene practice-based multicenter study. AB - PURPOSE: This randomized clinical multicenter study compared different professional preventive approaches on peri-implant inflammation under supportive implant therapy (SIT). METHODS: 105 participants (167 implants) were randomly allocated to four groups. All participants were under SIT with a 3-month recall interval. Plaque removal was performed by using manual curettes, a sonic-driven scaler, and a prophylaxis brush (Group A), supplemented by chlorhexidine (CHX) varnish on the implant surfaces (Group C) or by using manual curettes, air polishing with glycine powder, and a prophylaxis brush (Group B), supplemented by treatment with CHX varnish on the implant surfaces (Group D). The peri-implant probing depths (PPD), mucosal recession (MR), and bleeding on probing (BOP) on implants were determined at baseline. After 12 months, the final PPD, MR, and BOP on implants were assessed. The statistical evaluation consisted of Kruskal-Wallis test, Wilcoxon-test and Chi-squared test modified according to McNemar (P< 0.05). RESULTS: 62 subjects (n= 101 implants) were available for assessment. In Groups A, C, and D, no significant implant-related differences between baseline and follow-up were found in PPD, MR, and BOP. Group B showed a significant difference (P= 0.022) between baseline (1.77 +/- 1.58 mm) and follow-up (2.31 +/- 1.54 mm) in PPD. The location of implant (P= 0.02), the type of implant (P= 0.01), and the age of subject (P= 0.04) had significant influences on BOP. CLINICAL SIGNIFICANCE: All strategies were effective in preventing peri-implant inflammation. The supplemental application of chlorhexidine varnish had no significant additional benefit. PMID- 29178701 TI - Fracture resistance of endodontically-treated mandibular molars restored with different intra-radicular techniques. AB - PURPOSE: To evaluate fracture resistance and failure mode of endodontically treated mandibular molars restored with different intra-radicular techniques. METHODS: 75 human mandibular molars were randomly divided into five equal groups. Teeth were standardized, endodontically-treated and restored according the assigned group as follows: amalgam core only, prefabricated titanium post in the distal canal and amalgam core, composite core only; fiber post in the distal canal and composite core. One group of untreated sound teeth was used as a control. Non-precious metal crowns were fabricated and cemented on the prepared specimens with Rely X U200 resin cement. All specimens were subjected to a compressive load at crosshead speed 0.5 mm/minute, 25 degrees to the long axis of the tooth. Failure loads and modes were recorded. RESULTS: Mean failure loads among the groups were significantly different (P= 0.035). Post-hoc multiple pair wise comparisons revealed the amalgam core and composite core groups produced significantly lower fracture resistance than the control group (P= 0.041 and P= 0.025, respectively) and no significant differences among the different intra radicular techniques (P> 0.05). The composite core with fiber post and amalgam core with titanium posts showed the highest percentage of favorable failures (67%) and non-favorable failures (87%) respectively. CLINICAL SIGNIFICANCE: The composite core with fiber post is the most appropriate intraradicular restoration in cases of severely compromised molars. PMID- 29178702 TI - Clinical efficacy of resin-based materials for dentin hypersensitivity treatment. AB - PURPOSE: To evaluate the effect of three resin-based materials in the treatment of dentin hypersensitivity (DH) up to a 6-month follow-up. METHODS: 30 participants (179 teeth) with DH were enrolled in this randomized, double-blind, controlled clinical study. The teeth were randomly allocated into one of three groups: CV (resin-modified glass ionomer varnish - Clinpro XT Varnish), CP (fluoride-containing self-etch adhesive - Clearfil SE Protect) and GB (glutaraldehyde-containing etch-and-rinse adhesive - Gluma 2 Bond). The materials were applied according to the manufacturer's instructions. DH was evaluated by subjects' perception measured on a 0-10 visual analog scale (VAS) after evaporative (air blast) stimuli. The scores were recorded at baseline, immediately and at 1, 3 and 6 months after treatment. The data were analyzed by a two-way ANOVA with repeated measures for "time" and Games-Howell test (alpha = 0.05). RESULTS: ANOVA detected statistically significant differences among the time intervals, but not among the materials or interactions. There was a significant decrease in sensitivity scores from baseline to all the time points (P< 0.05). However, the differences were not statistically significant among the follow-ups, from immediately until 6 months after treatment (P> 0.05). All the resin-based materials were able to reduce DH up to 6 months after treatment. CLINICAL SIGNIFICANCE: Resin-based materials used as desensitizing agents were effective in reducing DH after a 6-month period and so could be recommended as a safe treatment for sensitive teeth. PMID- 29178703 TI - Bond strength and cement-tooth interfacial characterization of self-adhesive composite cements. AB - PURPOSE: (1) To determine the microtensile bond strength (uTBS) of self-adhesive (SA) composite cements to unetched/etched enamel and dentin, and (2) to characterize the cements' interaction with tooth tissue. METHODS: 51 composite blocks were bonded to smear layer-covered enamel and dentin (three teeth per group). Four SA composite cements (Clearfil SA, G-CEM, RelyX Unicem, SmartCem2), and three multi-step composite cements, two used following an etch-and-rinse (E&R) approach (RelyX ARC, Variolink II 'E&R') and one used following a self-etch (SE) approach (Variolink II ' SE') were investigated. The cement-tooth specimens were perpendicularly sectioned into micro-specimens (1.0 * 1.0 mm) in order to measure the uTBS. The data were statistically analyzed by ANOVA followed by Tukey HSD (P< 0.05). 24 additional specimens (four teeth per group) were prepared for interfacial characterization using SEM. RESULTS: The tested SA cements bonded equally well to enamel and dentin. Etching of enamel improved their bonding effectiveness, which however remained inferior to that of both E&R cements. SEM revealed a very similar interfacial ultrastructure at smear layer-covered enamel and dentin for the SA cements, exhibiting very superficial interaction at enamel and absence of a clearly detectable hybrid layer and resin tags in the dentin tubules. When the SA composite cements were applied to dentin free of a smear layer, regular and long resin tags were formed. CLINICAL SIGNIFICANCE: No significant differences in bonding effectiveness were recorded for the self adhesive composite cements when bonded to unetched/etched enamel and to dentin. Multi-step etch-and-rinse composite cements showed a better bonding effectiveness to enamel, although this could be approximated by the self-adhesive composite cements when enamel was acid-etched beforehand. On dentin, however, the bond strength of the etch-and-rinse composite cement RelyX ARC was superior. PMID- 29178704 TI - Occlusal stress is involved in the formation of non-carious cervical lesions. A systematic review of abfraction. AB - PURPOSE: This systematic review on abfraction studied whether stress is a mechanism in the formation of non-carious cervical lesions (NCCLs). METHODS: A literature search was performed on three electronic databases (PubMed, ISI Web of Science, and EMBASE) using the keyword "abfraction" in publications published in English. The inclusion criteria were clinical and laboratory studies that investigated the role of abfraction in NCCLs. The title and abstract of the identified publications were screened by two investigators independently. Reviews, case reports, and irrelevant papers were excluded. Full text of the remaining publications were retrieved. A manual search was performed on the bibliographies of the selected publications to identify additional relevant publications for review. RESULTS: A total of 372 publications were identified, and 165 duplicated publications and 166 irrelevant publications were excluded. From the bibliographies of the remaining 41 publications, 28 relevant publications were found. Therefore, 69 publications (31 clinical studies and 38 laboratory studies) were included in this review and the majority (56/69, 81%) found an association between occlusal stress and NCCLs. Although no clinical study demonstrated that NCCL was caused by stress alone, 23 studies reported that stress or occlusal factors were associated with NCCLs. Of the 38 laboratory studies, 24 that used finite element analysis found that stress was concentrated at the cervical region of the tooth. Nine laboratory studies suggested that stress was a mechanism for NCCLs, whereas five studies reported the opposite. In conclusion, current literature supported an association between occlusal stress and NCCLs. CLINICAL SIGNIFICANCE: This systematic review of abfraction found the majority of studies reported an association between occlusal stress and non carious cervical lesions. PMID- 29178705 TI - Effectiveness of dentifrices with new formulations for the treatment of dentin hypersensitivity - A meta-analysis. AB - PURPOSE: This meta-analysis was conducted to evaluate if strontium-acetate- and arginine-containing dentifrices can significantly reduce dentin hypersensitivity (DH). METHODS: A systematic literature search was performed. The investigation period was from 2006 to 2015 with the search term "dentin hypersensitivity". Nine original articles were relevant. A network meta-analysis of combined z scores was performed. Pooled results from random effects models with their 95% confidence intervals are reported. RESULTS: The results from the random effects network meta analysis show a significant improvement for the agents strontium acetate, arginine, and arginine with whitener, at all times for all stimuli, in comparison with the placebo. Strontium chloride is equivalent to the placebo. None of the dentifrices had a negative effect on DH. This meta-analysis showed that strontium acetate- and arginine-containing dentifrices can significantly reduce DH. Calcium sodium silicate and potassium nitrate formulas show a tendency for pain relief. Because of the limited power of the available studies, a randomized study with several agents is recommended. CLINICAL SIGNIFICANCE: The aim of the treatment of dentin hypersensitivity (DH) is pain relief. Dentifrices with formulations of strontium acetate, of arginine or of arginine with whitener seem to have a good impact in the therapy of DH and can be recommended for daily use. PMID- 29178706 TI - Stress distribution of bulk-fill resin composite in class II restorations. AB - PURPOSE: To study the influence of the resin bonding layer thickness and the bulk filling material stiffness in adhesive class II mesio-occlusal-distal (MOD) restorations using numerical finite element analysis (FEA). METHODS: Four 3D-FE models of teeth restored with different filling material stiffness and resin bonding layer thickness were built-up and analyzed. The 3D model of a sound lower molar was also analyzed and compared with restored ones. The tooth tissues (enamel, dentin), dental restoration and bolus on the occlusal surface, was divided into 3D solid CTETRA elements with four grid points. The adhesive bonding around the dental restoration was modeled with shell elements. Polymerization shrinkage was simulated with a thermal expansion approach. Mechanical behavior of restored models in terms of stress and displacement distributions, under the combination effects of polymerization shrinkage and occlusal load (600 N), was analyzed. All the materials were assumed to behave as elastic materials throughout the entire deformation. RESULTS: Numerical results show that the mechanical response of the restored models was very different compared to the sound tooth ones, where the stress was uniformly distributed from enamel to dentin with no critical stress concentration. In the restored models, the highest stress values were detected in the enamel, near the enamel-dentin interface and in the bulk restorative material. Tooth preparations A and B showed lower gradient stresses than corresponding C and D. The value of the vertical displacement components in models A and B were higher than corresponding C and D. The maximum displacement values were mainly located around the groove and were higher by an order of magnitude than the sound models. The results showed better mechanical response with models A and B compared to C and D. It is also evident that resin bonding thickness slightly affected the stress level of the restored teeth. CLINICAL SIGNIFICANCE: Class II MOD direct bulk resin composite restorations showed a high susceptibility to damage at the marginal and internal tissue interfaces depending on their own stiffness. The use of resin-based bulk filling materials is not recommended for large class II MOD adhesive restorations due to mechanical behavior failure risk. PMID- 29178707 TI - Effect of CAD/CAM glass fiber post-core on cement micromorphology and fracture resistance of endodontically treated roots. AB - PURPOSE: To investigate the fracture resistance of weakened roots restored with prefabricated or CAD/CAM-customized posts and cores as well as the thickness of the cement film and the presence of voids in the cement. METHODS: The roots of 40 human premolars were weakened by removing internal dentin with a diamond bur (2.5 mm in the coronal third and 1.5 mm in the apical third) and restored with prefabricated posts (PPs) or customized posts (CPs) with or without a zirconia crown (n= 10). Posts and crowns were cemented with resin cement. Microtomography was used to determine the thickness of the cement film and whether voids were present. After fatigue testing (1 million cycles, 50 N, 5 Hz, 36.5 degrees C), the specimens underwent compression testing with an oblique load (30 degrees , 1 mm/minute) and fracture strengths were recorded (N). Fracture strength and film thickness were analyzed with ANOVA and the Games-Howell test; the variable presence of voids was analyzed with the Mann-Whitney test (alpha= 5%). RESULTS: Mean fracture strengths varied between 640.4 and 792.9 N and did not differ significantly between groups. The CP group had a thinner cement film and fewer voids than the PP group. There was a positive, statistically significant correlation (Spearman, R=0.488, P= 0.029) between these variables. CLINICAL SIGNIFICANCE: CAD/CAM-manufactured glass-fiber posts and cores do not affect the fracture strength of flared root canals or cause catastrophic failure of the root when used with zirconia crowns. PMID- 29178708 TI - Influence of extremely high irradiances on the micromechanical properties of a nano hybrid resin based composite. AB - PURPOSE: To investigate in vitro the effect of extremely high irradiance light emitting diode (LED) light curing units (LCU) with different exposure distances and curing modes on the micromechanical properties of a nano hybrid resin based composite. METHODS: 72 resin based composite (RBC) (Kalore) specimens with 2 mm thickness were cured using two high irradiance LED LCUs (Bluephase 20i and FlashMax P3) at 0 and 7 mm exposure distances. The curing conditions were:a) Bluephase 20i - 10 seconds - High power; b) Bluephase 20i - 15 seconds - High power; c) Bluephase 20i - 5 seconds - Turbo; d) Bluephase 20i - 15 seconds - Soft start; e) FlashMax P3 - 4 mm tip cover - 3 seconds; f) FlashMax P3 - without tip cover - 3 seconds. The incident and transmitted irradiance and radiant exposure were evaluated in real time during curing, with a radiometer (MARC Resin Calibrator). The micromechanical properties (Vickers hardness, HV and indentation modulus, E) were measured with an automatic universal hardness indenter after storing specimens for 24 hours in distilled water. Data were analyzed with one- and two-way ANOVA tests followed by Tukey test and partial eta-square statistics (alpha= 0.05). RESULTS: For both LCUs, incident irradiance decreased progressively with increased exposure distance, reaching at 7 mm exposure distance less than 50% of the value measured when the LCU was applied directly on specimen's surface. In descending order of strength of their effects, the parameters incident irradiance (HV; eta P2 =0.828, E; 0.693), LCU (HV, 0.257, E, 0.043) and exposure distance (HV, 0.031, E, 0.028) were significant factors affecting HV and E (P < 0.05). The localized radiant exposure (the incident and transmitted) as well as the position of HV and E measurements (top-bottom of the specimen) were additional factors affecting significantly only HV (P < 0.05), but not E (P > 0.05). CLINICAL SIGNIFICANCE: Extremely high irradiances were less efficient in adequate curing of the analyzed nano hybrid composite. Using a protection tip, as clinically indicated, reduces the irradiance of FlashMax P3 from 7,681.7 (160.53) mW/cm2; to 3052.5 (71.61) mW/cm2;. PMID- 29178709 TI - Determination of polymerization shrinkage of different composites using a photoelastic method. AB - PURPOSE: To investigate the polymerization shrinkage stress of different low viscous bulk composites (SDR, Venus Bulk Fill, X-tra Base, Filtek Bulk Fill) in comparison to a conventional flowable composite (Filtek Supreme XTE Flow) and to high viscous bulk and conventional composites (Filtek Supreme XTE, GrandioSO, Tetric EvoCeram, Tetric EvoCeram BulkFill, Venus Diamond, Venus Pearl), as well as to an experimental composite (Ormocer) and a sonic-activated bulk fill composite (Sonicfill), by means of photoelastic investigation. METHODS: To ensure bonding of the resin composite, cylindrical cavities (O 4mm) in araldite B epoxide resin plates (40 * 40 * 4 mm3) were pre-treated with the Rocatec system. Embedded in araldite plates, six resin composite specimens of each material were exposed for 60 seconds from one side (Translux Power Blue, 1,000 mW/cm2). The samples were stored, light-protected and dry (23 degrees C). Polymerization shrinkage stress data (MPa) were calculated 15 minutes, 1 and 24 hours after light exposure, based on the diameter of the isochromatic curves of first order, obtained from araldite plates. Statistical analysis was performed with the Wilcoxon-test and Bonferroni correction (P< 0.0006). RESULTS: After 15 minutes/1 hour, the mean polymerization stress values calculated were:for SDR 4.4 +/- 0.1/4.4 +/- 0.2 MPa; Venus Bulk Fill 4.8 +/- 0.3/4.9 +/- 0.3 MPa; X-tra Base 6.5 +/- 0.3/6.7 +/- 0.3 MPa; Filtek Bulk Fill 4.9 +/- 0.3/4.9 +/- 0.3 MPa; Filtek Supreme XTE Flow 8.0 +/- 0.3/8.2 +/- 0.2 MPa; Filtek Supreme XTE 7.1 +/- 0.1/7.4 +/- 0.2 MPa; GrandioSO 6.3 +/- 0.4/6.3 +/- 0.3 MPa; Tetric EvoCeram 4.5 +/- 0.1/4.6 +/- 0.1 MPa; Tetric EvoCeram BulkFill 4.9 +/- 0.2/5.0 +/- 0.3 MPa; Venus Diamond 3.7 +/- 0.3/3.8 +/- 0.3 MPa; Venus Pearl 3.9 +/- 0.2/4.0 +/- 0.2 MPa, Sonicfill 5.4 +/- 0.2/5.6 +/- 0.3 MPa; and Ormocer (experimental) 4.1 +/- 0.2/4.3 +/- 0.2 MPa. After 24 hours, the following mean stress values were obtained:SDR 4.7 +/- 0.2 MPa; Venus Bulk Fill 5.1 +/- 0.2 MPa; X-tra Base 7.2 +/- 0.4 MPa; Filtek Bulk Fill 5.3 +/- 0.3 MPa; Filtek Supreme XTE Flow 8.7 +/- 0.3 MPa; Filtek Supreme XTE 7.9 +/- 0.2 MPa; GrandioSO 7.0 +/- 0.4 MPa; Tetric EvoCeram 4.9 +/- 0.1 MPa; Tetric EvoCeram BulkFill 5.4 +/- 0.3 MPa; Venus Diamond 4.5 +/- 0.3 MPa; Venus Pearl 4.5 +/- 0.3 MPa, Sonicfill 5.8 +/- 0.2 MPa and Ormocer (experimental) 4.5 +/- 0.2 MPa. The new and experimental resin composites showed significantly less polymerization shrinkage stress than the conventional resin composite (Filtek Supreme XTE). CLINICAL SIGNIFICANCE: Resin composite restoratives differ in their polymerization shrinkage stress development, independent of their viscosity. Some low viscosity bulkfill-restoratives generate less shrinkage stress compared to other conventional or bulk-restoratives. Practitioners should yield to the potential effect of shrinkage stress development, because this might affect marginal integrity in the clinical performance. PMID- 29178710 TI - Effect of conventional and contemporary disinfectant techniques on three peri implantitis associated microbiotas. AB - PURPOSE: To evaluate the antiseptic properties of five different disinfectant techniques on three different peri-implantitis (PI) associated biofilms. METHODS: 90 implant titanium disks, with the same thickness and diameter, were prepared and randomly divided into 18 groups (n = 5) based on the microbiota strains (S. aureus, S. epidermidis and C. albicans) and using the following disinfectant techniques:soft laser therapy, photodynamic therapy (PDT), 0.12% NaOCl, 0.2% chlorhexidine, 3% H2O2, and control groups. After forming a protein layer on disk surfaces, the specimens were exposed to the microbial suspensions. After decontamination according to designated techniques, 2% Trypsin protease was administered to isolate the surviving microorganisms. Muller Hinton agar culture was used for microbiota growth. After 48-hour incubation, the standard colony forming unit (CFU) was assayed and the collected data were analyzed by Kruskal Wallis and Mann-Whitney tests at a significance level of 0.05. RESULTS: The highest amount of CFU/ml values was shown by C. albicans, which was subjected to PDT (25.12 +/- 30.23). The least disinfecting efficacy on S. epidermidis was demonstrated by the laser group (all P-values <= 0.01). Nevertheless, all of the groups exhibited significant differences with the control groups (all P-values < 0.01). CLINICAL SIGNIFICANCE: None of the studied disinfectant techniques had the highest lethal effects on all of the tested microbiotas. Therefore, a combination of these disinfectant techniques, for instance PDT + 3% H2O2 or 0.2% chlorhexidine, is recommended. PMID- 29178711 TI - Efficacy of an experimental 3% potassium nitrate mouthwash in providing long-term relief from dentin hypersensitivity:An 8-week randomized controlled study (Study 1). AB - PURPOSE: To evaluate the efficacy of an experimental mouthwash containing 3% potassium nitrate (KNO3) in relieving dentin hypersensitivity when used as an adjunct to brushing with fluoride toothpaste compared with use of the same toothpaste alone. METHODS: This was one of three randomized, two-treatment, examiner-blind, parallel-design, single-site, 8-week studies in healthy subjects with self-reported and clinically diagnosed dentin hypersensitivity. Subjects were randomized to receive either fluoride toothpaste plus 3% KNO3 mouthwash or the same fluoride toothpaste alone, and instructed to use their allocated treatment twice daily for the next 8 weeks. Dentin hypersensitivity was evaluated at baseline and following 4 and 8 weeks of treatment through assessment of responses to evaporative (air) and tactile stimuli [measured by the Schiff Sensitivity Scale, a visual rating scale (VRS), and tactile threshold, respectively], and using the Dentin Hypersensitivity Experience Questionnaire (DHEQ; a validated quality-of-life instrument for dentin hypersensitivity). RESULTS: A total of 216 subjects were randomized and 214 completed the study. Both treatment groups demonstrated statistically significant reductions from baseline for each clinical measure of sensitivity (P<= 0.01) at Weeks 4 and 8. Use of the 3% KNO3 mouthwash after brushing with fluoride toothpaste resulted in statistically significantly greater reductions in sensitivity to an evaporative (air) stimulus (mean Schiff score and mean VRS, P< 0.001; primary objective mean Schiff score at Week 8, P< 0.0001) and statistically significantly higher tactile threshold (P< 0.001) at Weeks 4 and 8 compared with toothpaste alone. The DHEQ responses reflected the clinical outcomes for several parameters, indicating a significant improvement in oral health-related quality of life after 8 weeks' use of the 3% KNO3 mouthwash. CLINICAL SIGNIFICANCE: The results of this study suggest that daily use of a 3% KNO3 mouthwash as an adjunct to brushing with fluoride toothpaste provides clinically relevant improvements in dentin hypersensitivity after 8 weeks' twice-daily use. PMID- 29178712 TI - Role of tyrosol on Candida albicans, Candida glabrata and Streptococcus mutans biofilms developed on different surfaces. AB - PURPOSE: To assess the effect of tyrosol on the production of hydrolytic enzymes (by Candida biofilm cells) and acid (by Streptococcus mutans biofilms), as well as to quantify single and mixed biofilms of these species formed on acrylic resin (AR) and hydroxyapatite (HA). METHODS: Candida and S. mutans biofilms were formed on AR and HA in the presence of tyrosol during 48 hours. Next, acid proteinase, phospholipase and hemolytic activities of Candida biofilm cells were determined, while acid production by S. mutans biofilms was assessed by pH determination. The effect of tyrosol on mature biofilms (96 hours) was evaluated through quantification of total biomass, metabolic activity, number of colony-forming units and composition of biofilms' extracellular matrix. Data were analyzed by one- and two-way ANOVA, followed by Tukey's and Holm-Sidak's tests (alpha = 0.05). RESULTS: Treatments with tyrosol were not able to significantly reduce hydrolytic enzymes and acid production by Candida and S. mutans. Tyrosol only significantly reduced the metabolic activity of single biofilms of Candida species. CLINICAL SIGNIFICANCE: Tyrosol on its own had a limited efficacy against single and mixed-species oral biofilms. Its use as an alternative antimicrobial for topical therapies still demands more investigation. PMID- 29178713 TI - Influence of manual and power toothbrushes on clinical and microbiological findings in initial treatment of periodontitis - A randomized clinical study. AB - PURPOSE: This randomized clinical study compared the influence of manual and power toothbrushes on clinical and microbiological findings in initial treatment of periodontitis. METHODS: A total of 72 participants with a mean age of 55.7 years were randomly assigned to three groups (n= 24):oscillating-rotating (OR), sonic-active (SA) and manual toothbrush (MTB). At baseline, after 4 weeks and after 12 weeks, the following parameters were assessed:modified Quigley-Hein Index (QHI), papilla bleeding index (PBI), periodontal pocket depth (PPD), bleeding on probing (BOP) and recession. For microbiological analysis (PCR) of 11 periodontal pathogenic bacteria, samples of sulcular fluid were taken from the deepest pockets. Statistical analysis was performed using ANOVA, with the level of significance set at alpha= 5%. RESULTS: All clinical parameters:PBI, modified QHI, PPD, BOP and recession showed an improvement after 12 weeks compared to baseline, regardless of which toothbrush system was used. Regarding PBI, the SA group showed significantly greater improvement compared to OR and MTB (P< 0.01). In plaque removal (QHI) only OR was significantly more effective than MTB (P= 0.01). Periodontal parameters showed a significantly higher reduction of PPD for SA compared to MTB and MTB compared to OR (Plt; 0.05), while for BOP only a significantly higher reduction in SA compared to OR was detected (P= 0.01) Microbiological analysis showed an improvement in prevalence of several bacteria without significant differences between groups. CLINICAL SIGNIFICANCE: Patients might benefit from powered TB systems, especially in initial treatment of periodontitis. PMID- 29178714 TI - Fluoride release and re-release from various esthetic restorative materials. AB - PURPOSE: To measure the amount of fluoride release and re-release after re-charge from two commonly used esthetic restorative materials and compare it to a new experimental material. METHODS: 30 standardized disc-shaped specimens were fabricated using resin-based composite (Z100), resin-modified glass-ionomer cement (Vitremer) and a new experimental material which is a self-curing resin based composite with light curing option. 10 specimens were made from each material. The specimens of each group were immersed separately in 10 ml distilled water. Fluoride release was measured after 1, 7, 14 and 30 days using a fluoride specific ion electrode and an ion-analyzer. The specimens were then exposed to 2.0% neutral sodium fluoride foam (0.9% fluoride ion). The amount of fluoride re released was measured at Days 1, 7, 14 and 30. RESULTS: An ANOVA indicated a statically significant variance among the groups (P< 0.001). The experimental group demonstrated significantly less fluoride release at Day 1 compared to Day 31 (first day after 2% sodium fluoride application). At Days 7, 14 and 30 there was significantly more fluoride release than Day 7, 14 and 30 after the topical fluoride application (P< 0.001). There was significantly more fluoride release from Vitremer than the experimental material at Days 1 and 7. However, similar release was observed at Days 14 and 30 for Vitremer and experimental material, but not for Z100. Both Vitremer and the experimental material showed significantly more release of fluoride compared to Z100 at all time points. CLINICAL SIGNIFICANCE: This study demonstrates that the new experimental material released fluoride, re-charged and re-released fluoride at a level comparable to Vitremer but more than Z100. PMID- 29178715 TI - Effects of atmospheric non-thermal argon/oxygen plasma on biofilm viability and hydrophobicity of oral bacteria. AB - PURPOSE: To evaluate the bactericidal effects of atmospheric non-thermal argon/oxygen plasma on in vitro oral biofilms constructed from S. mutans and/or S. sanguinis, and the influence of the plasma on the virulence properties of A. oris. METHODS: In vitro oral biofilms were constructed in the wells of 48-well plates from S. mutans and/or S. sanguinis. The wells containing constructed biofilms and various amounts of phosphate-buffered saline (PBS) were treated with non-thermal argon/oxygen plasma brush for 2 minutes. The methylthiazolyldiphenyl tetrazolium bromide (MTT) assay and Live/Dead assay were used to evaluate the viability of biofilms in those wells after the plasma treatments. Meanwhile, A. oris suspensions were treated with the plasma and then evaluated for their virulence properties by measuring the hydrophobicity and co-aggregation capability of treated A. oris. RESULTS: The MTT assay showed that exposure to non thermal plasma for 2 minutes significantly reduced the viability of bacteria in both single-species and two-species biofilms of S. mutans and S. sanguinis with the reductions of up to 99%. Meanwhile, plasma treatment also altered the hydrophobicity of A. oris, and reduced their capability to co-aggregate with S. sanguinis. CLINICAL SIGNIFICANCE: The results from this study demonstrated that atmospheric non-thermal argon/oxygen plasma could effectively deactivate oral bacteria biofilm by decreasing bacterial viability as well as reducing their hydrophobicity and co-aggregation capability. PMID- 29178716 TI - Clinical evaluation of a toothpaste containing lysozyme for the treatment of recurrent aphthous stomatitis: A 3-month, double-blind, randomized study. AB - PURPOSE: To assess the efficacy and safety of a toothpaste containing lysozyme for the treatment of minor recurrent aphthous stomatitis (MiRAS) in a 3-month clinical trial. METHODS: 71 participants with MiRAS were recruited to this randomized, parallel-controlled, double-blind clinical trial. Participants were allocated randomly to the test group or the control group. Demographic data and pain score (visual analogue scale, VAS) were recorded at baseline. Healing time of MiRAS, recurrence frequency and side effects were recorded at the 1-, 2- and 3 month follow-up visits. All data were analyzed using SAS software version 8.0. RESULTS: There was no significant difference (P>0.05) in pain score between the treatment group (3.00 +/- 1.66) and the control group (2.66 +/- 1.51). The average healing time was significantly reduced (P< 0.01) in the treatment group (5.66 +/- 2.02) compared with the control group (7.46 +/- 2.69), while the recurrence frequency also showed a significant reduction from 4.40 +/- 2.89 in the control group to 3.06 +/- 1.48 in the treatment group (P< 0.05). No obvious side effects were observed. CLINICAL SIGNIFICANCE: The results of this clinical study supported the conclusion that a toothpaste containing lysozyme was effective in promoting healing and reducing recurrence frequency without significant side effects in the treatment of minor recurrent aphthous stomatitis. PMID- 29178717 TI - The influence of the utilization time of brush heads from different types of power toothbrushes on oral hygiene assessed over a 6-month observation period: A randomized clinical trial. AB - PURPOSE: This randomized clinical trial investigated the influence of the utilization time of brush heads from different types of power toothbrushes [oscillating rotating (OR) and sonic action (SA)93; on oral hygiene (plaque accumulation and gingival inflammation) over a 6-month observation period. METHODS: 49 participants were randomly allocated into two groups: use of the same brush head over 6 months (NR: non-replacement) or replacement of brush head every 4 weeks over 6 months (R: replacement). Each group was subdivided into two subgroups according to kind of toothbrush (TB) used (OR and SA). Modified Quigley Hein plaque index (QHI), papilla bleeding index (PBI), and gingival index (GI) were recorded at baseline and 2, 8, 12, 16, and 24 weeks after baseline. After 24 weeks, participants of both groups (R and NR) received a new brush head. At week 26, final QHI, PBI, and GI were recorded. RESULTS: QHI decreased between baseline and follow-up visits in R groups (P< 0.05), with the exception of week 12 (P= 0.26). In NR groups, no significant decrease was detected (P> 0.05). There was no significant effect of time on PBI or GI in any of R subgroups (P> 0.05). In NR oscillating/rotating TB: significant increase in PBI and GI was detected 24 weeks after baseline (PBI: P= 0.02, GI: P= 0.03); sonic action TBs showed significant decrease in PBI at every follow-up visit (P< 0.05), except at 24 weeks after baseline (P= 0.73). GI was significantly decreased at 2 weeks after baseline only (P< 0.01). CLINICAL SIGNIFICANCE: Six-month use of the same brush head reduced effectiveness in removing plaque, and gingival inflammation appeared to increase after a utilization time of over 4 months. Replacing brush heads is advised after 4 months. PMID- 29178718 TI - Antimicrobial and antibiofilm activity of silver, titanium dioxide and iron nano particles. AB - PURPOSE: To compare the antimicrobial effects of chlorhexidine, penicillin, erythromycin, clindamycin, tetracycline and vancomycin with silver, titanium dioxide and iron nanoparticles and also to consider the synergistic antibacterial and antibiofilm effects of nanoparticles in clinical and standard strains of Streptococcus mutans and Streptococcus sanguinis. METHODS: The specimens collected from 66 3-5 year-old children with detected S. mutans and S. sanguinis by PCR were then exposed to the antimicrobial activity of chlorhexidine, penicillin, erythromycin, clindamycin, tetracycline and vancomycin with silver, titanium dioxide and iron nanoparticles measured by microdilution and disc diffusion tests and the colony counted after 1 to 5 minutes. The antibiofilm activity was examined by microtiter test. RESULTS: Use of nanoparticles alone showed higher minimum inhibitory concentration (MIC) than using them synergistically. The most effective synergistic solution was the one containing TiO2, Ag and Fe3O4 showing 0.019 MUg#47;ml in S. mutans and S. sanguinis. Furthermore, this solution had the lowest biofilm inhibitory concentration (BIC) and colony forming units than the other antibiotics and chlorhexidine. CLINICAL SIGNIFICANCE: The solution containing TiO2, Ag and Fe33O4 showed the lowest inhibitory and antibiofilm concentration against S. mutans and S. sanguinis compared to those of other nanoparticle containing solutions, antibiotics and chlorhexidine, thus it may be used for treating dental caries, dental plaque and oral infections. PMID- 29178719 TI - Quantitation of endotoxin and lipoteichoic acid virulence using toll receptor reporter gene. AB - PURPOSE: To apply quantitative Toll-like receptors (TLR) cell assays to compare lipopolysaccharides (LPSs) and lipoteichoic acids (LTAs) from different oral bacterial strains for potential pathogenicity in vitro. METHODS: The potency of LPS and LTA from different bacteria on activation of TLR reporter genes in HEK tlr cell lines was examined. P. gingivalis LPS mix, P. gingivalis 1690 LPS, P. gingivalis 1435/50 LPS, E. coli LPS (E. coli K12), B. subtilis LTA, S. aureus LTA, E. hirae LTA and S. pyogenes LTA were examined in both TLR2 and TLR4 HEK cell line reporter assays. Solutions of LPS and LTA from selected bacteria were applied in a dose response fashion to the TLR reporter cells under standard culture conditions for mammalian cells. Reporter gene secreted-embryonic-alkaline phosphatase (SEAP) was measured, and half maximal effective concentration (EC50) was determined for each sample. Concentration dependent TLR activation was compared to similar responses to LPS and LTA for commercial BODIPY-TR-Cadaverine and LAL biochemical (non cell based) assays. RESULTS: All LPS from P. gingivalis activated both TLR2 and TLR4 responses. E. coli LPS is a strong activator for TLR4 but not for TLR2 responses. In contrast, both B. subtilis and S. aureus LTA provoked responses only in TLR2, but not in the TLR4 assay. Interestingly, E. hirae LTA and S. pyogenes LTA did not stimulate strong TLR2 responses. Instead, both E. hirae LTA and S. pyogenes LTA mounted a reasonable response in TLR4 reporter gene assay. Both LPS and LTA showed deactivation of fluorescence in BODIPY-TR-Cadaverine while only LPS was active in LAL. As with biochemical assays, an EC50 could be determined for LPS and LTA from various bacterial strains. The EC50 is defined as a concentration of LPS or LTA that provokes a response halfway between the baseline and maximum responses. Lower EC50 means higher potency in promoting TLR responses, and in principle indicates greater toxicity to the host. CLINICAL SIGNIFICANCE: InvivoGen TLR2 and TLR4 assays distinguish specific types of microbial products, such as LPS and LTA from different bacteria. Application of EC50 determinations creates a means for quantitative and comparisons of LPS and LTA virulence in a cellular-based assay and combinations of TLR reporter cell assays along with biochemical evaluation of LPS#47;LTA in BODIPY-TR-Cadaverine and LPS in LAL assays provides a means to quantitate virulence of plaque samples with respect to both LPS and LTA. These learnings have long-term implications for patient care in that understanding the virulence of patients' plaque provides important information to assess risk of oral diseases. PMID- 29178720 TI - Lipopolysaccharide and lipoteichoic acid binding by antimicrobials used in oral care formulations. AB - PURPOSE: To study the reactivity of lipopolysaccharide (LPS) and lipoteichoic acid (LTA) with the cationically charged agents cetylpyridinium chloride, stannous fluoride, and the non-cationic agent triclosan. We also assessed the effect of these agents to inhibit LPS and LTA binding to cellular Toll-like Receptors (TLRs) in vitro. METHODS: The ability of these antimicrobials to bind with LPS and/or LTA was assessed in both the Limulus amebocyte lysate and BODIPY TR-cadaverine dye assays. Mass spectroscopy was then used to confirm that stannous fluoride directly binds with LPS and to determine stoichiometry. Lastly, we looked for possible inhibitory effects of these antimicrobial agents on the ability of fluorescently conjugated LPS to bind to TLR4 expressed on HEK 293 cells. RESULTS: Cetylpyridinium chloride (CPC) and stannous salts including stannous fluoride interfered with LPS and LTA reactivity in both dye assays, while triclosan had no effect. Mass spectroscopy revealed direct binding of stannous fluoride with E. Coli LPS at 1:1 stoichiometric ratios. In the cellular assay, cetylpyridinium chloride and stannous fluoride, but not triclosan, inhibited LPS binding to TLR4. CLINICAL SIGNIFICANCE: These results support a potential mechanism of action for stannous fluoride and CPC formulated in oral products in which these ingredients bind bacterial toxins and potentially render them less toxic to the host. These results may influence home care recommendations for patients at risk for plaque-related diseases. PMID- 29178721 TI - The new generation of conventional and bulk-fill composites do not reduce the shrinkage stress in endodontically-treated molars. AB - PURPOSE: To compare flowable and regular paste bulk-fill resin composites with old and new generation conventional composites that use incremental filling techniques for direct restoration of endodontically-treated teeth. METHODS: Four resin composites produced by the same company (3M-ESPE) were used: two conventional resin composites (old formulation, Z100, and new nanofilled formulation, Filtek Supreme XT); and two bulk-fill resin composites (flowable composite, Filtek Bulk-fill Flowable associated with Filtek Supreme, and regular paste, Filtek Bulk-fill Posterior). Elastic modulus (E), Vickers hardness (VH), post-gel shrinkage (Shr), diametral tensile strength (DTS) and compressive strength (CS) were determined (n= 10) and statistically analyzed using ANOVA and Tukey's test (alpha=0.05). Shrinkage stresses were analyzed using non-linear finite element analysis. RESULTS: Filtek Bulk-fill flowable and Filtek Supreme XT had higher CS than Z100 and Filtek Bulk-fill Posterior. Z100 and Filtek Supreme XT had higher DTS than Filtek Bulk-fill Posterior. Filtek Bulk-fill flowable had the lowest values and Z100 the highest E and Shr. Z100 resulted in higher stresses in the enamel and in root dentin close to the pulp chamber than the other filling techniques. Filtek Bulk-fill Flowable resulted in lower stress than other resin composites. CLINICAL SIGNIFICANCE: Using bulk-fill composites, especially flowable resin composite, created lower stresses in restored endodontically-treated teeth. Clinicians, when deciding for direct restoration of endodontically-treated teeth, may choose the bulk-fill composite to decrease undesirable effects of direct restoration while simplifying filling procedure. PMID- 29178722 TI - Case-specific finite element analysis of dental CAD/CAM prostheses to identify design flaws prior to manufacture. AB - PURPOSE: To apply a design optimization strategy to dental prostheses machining to verify whether this approach can detect flaws occurring in the CAD process and to estimate the influence of the type of material on the occurrence of fractures in restorations. METHODS: The stereo lithography interface format of a 4-unit (from canine to first molar) fixed dental prosthesis designed by a conventional dental CAD process was converted into a Finite Element Analysis (FEA) model. This basic model was coupled to the mechanical properties of feldspathic ceramic, lithium disilicate ceramic (LS2) and zirconia (ZrO2) to create three FEA models with different mechanical properties. The models were constrained along the abutment housing surfaces of the canine and the first molar, respectively. Finally, a simulated load of 50 N was applied vertically to the occlusal surface of the first premolar. RESULTS: The FEA showed a stress peak concentration between the second connectors and the second premolar. The stress peak overcame the ultimate tensile stresses of feldspathic and lithium disilicate ceramics; conversely, the ultimate tensile stress of zirconia was not overcome. A geometrical flaw was identified in the 4-unit fixed dental prosthesis. The flaw was sensitive to tensional stress and could lead to failure of the component. CLINICAL SIGNIFICANCE: The results of the present investigation showed the importance and future impact of the application of FEA in the daily practice of prosthodontics. A FEA-implemented CAD process would allow proper prosthetic volumes with correct dimensions of the framework, in order to withstand occlusal loads and consequently reduce mechanical failures. FEA is a useful tool to simplify the design of prosthetic frameworks and select esthetic ceramic materials with strength enough to withstand occlusal stress. PMID- 29178723 TI - Effects of desensitizing toothpastes on the permeability of dentin after different brushing times: An in vitro study. AB - PURPOSE: To investigate the effects of three commercially available desensitizing toothpastes on dentin permeability, and compare the efficacy of each product for reducing dentin permeability in the short term according to the frequency and duration of usage. METHODS: 100 dentin discs with no caries were prepared from freshly extracted human third molar teeth. The dentin discs were brushed with three desensitizing toothpastes or with a non-desensitizing toothpaste and distilled water, which served as control. The 100 dentin slices were randomly divided into two groups (n= 50): one group underwent continuous brushing (brushed for 3 minutes continuously), and the other group underwent discontinuous brushing (brushed three times, each time for 1 minute). Then, the two groups were divided into five subgroups (n = 10) for the five brushing applications. Dentin permeability was measured with a hydraulic permeability system before and after brushing. RESULTS: All desensitizing toothpastes reduced dentin permeability significantly after treatment. Sensodyne Repair and Protect (calcium sodium phosphosilicate) and discontinuous brushing reduced dentin permeability significantly compared with continuous brushing. Dentin permeability values showed no significant difference between the three toothpastes after 3 minutes of continuous brushing. When comparing the three toothpastes under discontinuous brushing conditions after 3 minutes, Sensodyne Repair and Protect (calcium sodium phosphosilicate) reduced dentin permeability significantly. CLINICAL SIGNIFICANCE: Sensodyne Repair and Protect (calcium sodium phosphosilicate) and discontinuous brushing reduced dentin permeability significantly compared with continuous brushing. Moreover, brushing with Sensodyne Repair and Protect (calcium sodium phosphosilicate) resulted in the lowest dentin permeability compared with those of the other two toothpastes. These results indicated that Sensodyne Repair and Protect may relieve dentin hypersensitivity. PMID- 29178724 TI - Effect of radiotherapy, adhesive systems and doxycycline on the bond strength of the dentin-composite interface. AB - PURPOSE: To investigate the effect of radiotherapy, doxycycline and adhesive systems on the microtensile bond strength (MUTBS) of the dentin-composite interface. METHODS: 60 human third molars were sectioned to expose middle dentin surface and distributed according to: (1) adhesive system (Adper Scotchbond MP and Clearfil SE Bond) applied, (2) application or not of doxycycline, and (3) submission to 60 Gy total radiation (2 Gy daily doses, 5 days/week for 6 weeks) before restoration procedure (RtRes); after restoration procedure (ResRt) or not submitted to radiotherapy (Control group). Specimens were tested for MUTBS and mode of failure were evaluated under optical microscopy. The bonding interface was evaluated with a scanning electron microscope (SEM). Data was submitted to three-way ANOVA and Tukey's test (alpha= 0.05). RESULTS: There was no significant difference between the MUTBS (MPa) of Adper Scotchbond MP (25.5+/-11.1) and Clearfil SE (27.6+/-9.1). Control (30.5+/-10.9) and ResRt (29.2+/-10.4) presented MUTBS significantly higher than RtRes (23.1+/-7.2). Doxycycline (21.7+/-7.6) significantly reduced MUTBS compared to groups without doxycycline application (33.6+/-8.6). Dentin cohesive failure mode was predominant for RtRes and mixed failure mode for ResRt. Mixed and adhesive failures were frequently observed in control groups. SEM showed adhesive penetration in dentin tubules in all groups, regardless of the radiotherapy and the application of doxycycline. The radiotherapy before composite restoration procedure decreased the MUTBS. No statistical difference was observed between the adhesive systems. The doxycycline reduced MUTBS regardless of the other conditions. CLINICAL SIGNIFICANCE: Composite restoration procedure should be done before radiotherapy, regardless of the adhesive system used. PMID- 29178725 TI - Efficacy of an anti-discoloration system (ADS) in a 0.12% chlorhexidine mouthwash: A triple blind, randomized clinical trial. AB - PURPOSE: To determine the efficacy of an anti-discoloration system (ADS) in a 0.12% chlorhexidine (CHX) mouthwash to reduce dental discoloration. METHODS: A triple-blind, cross-over, randomized clinical trial was carried out in 22 healthy volunteers asked to perform oral rinses, twice a day for 21 days, using 0.12% CHX mouthwashes containing or not ADS (wash-out= 21 days). Dental discolorations were compared via spectroscopy (DeltaE), and direct visual examination performed by the dentist and volunteers themselves. At 6 months, a further visual analysis on clinical images was carried out by the same volunteers and ad hoc recruited dental practitioners. RESULTS: A slight discoloration was the most frequent finding, independent of the presence of ADS, while the few severe cases of staining were associated with CHX alone. (DeltaE values comparing dental color before and after treatments were similar for CHX (8.4+/-0.1) and CHX+ADS (8.6+/ 0.9) rinses. Direct visual analysis showed no staining difference between the two mouthwashes. Six months later, volunteers' self-evaluation of clinical pictures again did not detect any significant difference between treatments, while dental practitioners identified CHX+ADS as less discoloring (< 0.05). Slight dental discoloration represents the most common side-effect of 0.12% CHX mouthwash, independent of the presence of ADS. Severe cases are possible, but very rare and mainly associated with CHX alone. CLINICAL SIGNIFICANCE: There was no evidence to support the 0.12% chlorhexidine with anti-discoloration agent to reduce staining. PMID- 29178726 TI - Shear bond strength of different materials used as core build-up to ceramic. AB - PURPOSE: To determine the performance of a resin composite material specially developed for core build-ups in comparison with conventional restorative materials. METHODS: 90 roughened ceramic blocs were divided into three groups; one group (n=30) was used for the core build-up material (Gradia Core) and the other two groups (n=30, each) were used for two conventional restorative materials (Tetric EvoCeram, Compoglass F). After adhesive fixation, specimens of each material were subdivided in accordance with the storage conditions (thermocycling or water storage). Shear bond strength was measured and fracture behavior was analyzed. RESULTS: Gradia Core presented significantly higher shear bond strength values than the conventional restorative material Tetric EvoCeram, both after 24 hours water storage as well as after thermocycling. Compoglass F did not show any statistically significant differences compared to the other materials, independent of the storage condition. However, Compoglass F resulted in numerically higher shear bond values than Tetric EvoCeram, but lower shear bond values than Gradia Core. Within the same materials, no statistically significant differences occurred regarding the storage conditions. CLINICAL SIGNIFICANCE: The specific core build-up material provided stronger bonding properties when luted to feldspar ceramic than conventional restorative materials, making it a suitable supporting material when high-quality esthetic restorations are needed for restoring decayed, but vital teeth. PMID- 29178727 TI - Performance of CAD/CAM fabricated fiber posts in oval-shaped root canals: An in vitro study. AB - PURPOSE: To assess the push-out strength, the cement layer thickness and the interfacial nanoleakage of prefabricated fiber posts, CAD/CAM fiber posts and metal cast posts cemented into oval-shaped root canals. METHODS: Oval-shaped post spaces were prepared in 30 single-rooted premolars. Roots were randomly assigned to three groups (n=10), according to the post type to be inserted: Group 1: Prefabricated fiber post (D.T. Light-Post X-RO Illusion); Group 2: Cast metal post; Group 3: CAD/CAM-fabricated fiber post (experimental fiber blocks). In Group 3, post spaces were sprayed with scan powder (VITA), scanned with an inEos 4.2 scanner, and fiber posts were milled using an inLab MC XL CAD/CAM milling unit. All posts were cemented using Gradia Core dual-cure resin cement in combination with Gradia core self-etching bond (GC). After 24 hours, the specimens were sectioned perpendicular to the long axis into six 1 mm-thick sections, which were differentiated by the root level. Sections from six roots per group were used to measure the cement thickness and subsequently for the thin slice push-out test, whereas the sections from the remaining four teeth were assigned to interfacial nanoleakage test. The cement thickness around the posts was measured in micrometers (um) on the digital images acquired with a digital microscope using the Digimizer software. Thin-slice push-out test was conducted using a universal testing machine at the crosshead speed of 0.5 mm/minute and the bond strength was expressed in megaPascals (MPa). The interfacial nanoleakage was observed under light microscope and quantified by scoring the depth of silver nitrate penetration along the post-cement-dentin interfaces. The obtained results were statistically analyzed by Kruskal-Wallis ANOVA, followed by the Dunn's Multiple Range test for post hoc comparisons. The level of significance was set at P< 0.05. RESULTS: Statistically significant differences were found among the groups in push-out bond strength, cement thickness and interfacial nanoleakage (P< 0.05). CAD/CAM-fabricated fiber posts achieved retention that was comparable to that of cast metal posts and significantly higher than that of prefabricated fiber posts. The cement layer thickness around CAD/CAM-fabricated fiber posts was significantly lower than around prefabricated fiber posts, but higher than that around cast metal posts. Root level was not a significant factor for push-out strength in any of the groups, whereas it significantly affected cement layer thickness only in the prefabricated fiber post group. No differences were observed in interfacial nanoleakage between CAD/CAM fabricated and prefabricated fiber posts, while nanoleakage recorded in cast metal posts was significantly lower. CLINICAL SIGNIFICANCE: CAD/CAM fabricated fiber posts could represent a valid alternative to traditionally used posts in the restoration of endodontically-treated teeth with oval or wide root canals, offering the advantages of better esthetics, retention, and cement thickness values that are comparable to cast post and cores. PMID- 29178728 TI - A randomized clinical study to evaluate the effect of an ultra-low abrasivity dentifrice on extrinsic dental stain. AB - PURPOSE: To investigate the stain-removal efficacy of an experimental ultra-low abrasivity anti-sensitivity dentifrice containing sodium tripolyphosphate (STP) and a cocamidopropyl betaine/sodium methyl cocoyl taurate detergent system. METHODS: This was a single-center, examiner-blind, randomized, parallel-group study. Extrinsic dental stain was assessed on the facial surfaces of the six maxillary and six mandibular anterior teeth and the lingual surfaces of the six mandibular anterior teeth using the Macpherson modification of the Lobene Stain Index (MLSI). Treatments were: ultra-low abrasivity dentifrice [5% w/w KNO3, 5% w/w STP, 1,100 ppm fluoride as sodium fluoride; relative dentin abrasivity (RDA) ~10; n=54]; moderate abrasivity fluoride dentifrice (1,100 ppm fluoride as sodium monofluorophosphate; RDA ~68; n= 57); higher abrasivity daily-use whitening dentifrice (1,100 ppm fluoride as sodium fluoride; RDA~137; n= 57). Subjects brushed for 1 minute, twice daily, for 8 weeks. RESULTS: Mean total MLSI [ Area * Intensity (A*I) ] change from baseline score at Weeks 4 and 8 was significant (P< 0.0001) for all groups. At Week 8, for the ultra-low abrasivity dentifrice versus the moderate and higher abrasivity dentifrices, mean total MLSI (A*I) scores (P< 0.0001), along with MLSI endpoints in facial, lingual, and interproximal regions (P= 0.0035 to P< 0.0001), favored the ultra-low abrasivity dentifrice. Dentifrices were generally well-tolerated. The ultra-low abrasivity dentifrice containing 5% STP reduced extrinsic dental stain more effectively than moderate or higher abrasivity dentifrices. CLINICAL SIGNIFICANCE: The ultra-low abrasivity, anti-sensitivity dentifrice containing 5% STP reduced extrinsic dental stain more effectively than moderate or higher abrasivity dentifrices, and is thus suitable for patients with sensitive teeth who wish to control extrinsic dental stain. PMID- 29178729 TI - Surface properties and color stability of incrementally-filled and bulk-fill composites after in vitro toothbrushing. AB - PURPOSE: To evaluate the effect of simulated toothbrush abrasion on the surface gloss, the surface roughness and the color stability of incrementally-filled and bulk-fill composites. METHODS: 48 dimensionally standardized composite specimens (n= 8/group) were made from four incrementally-filled composites (Tetric EvoCeram, IPS Empress Direct Enamel, Ceram X mono and Arabesk) and two bulk-fill composites (Quix fil and Tetric EvoCeram Bulk). Before and after toothbrushing simulation the surface gloss was measured by a glossmeter, the surface roughness was evaluated with a profilometer, and the color was measured using a spectrophotometer. RESULTS: Before and after the toothbrush abrasion, IPS Empress Direct Enamel yielded the highest gloss value, while Ceram X mono exhibited the lowest gloss value. Quix fil showed the highest Ra value before the toothbrushing simulation, however, it showed similar Ra value with Ceram X mono and Arabesk after the toothbrushing simulation. IPS Empress Direct Enamel showed the lowest DeltaE after the simulated toothbrushing. Tetric EvoCeram Bulk showed similar gloss value, Ra value, and DeltaE to Tetric EvoCeram after the toothbrushing simulation. Simple regression analysis showed no correlation between the roughness and the gloss, but it showed a positive linear relationship between DeltaE and DeltaRa. (R2= 0.863, P= 0.027). CLINICAL SIGNIFICANCE: The evaluated bulk-fill composites did not exhibit significantly worse surface properties and color stability than incrementally-filled materials after toothbrush abrasion. Color changes of composites caused by toothbrush abrasion were acceptable on the premise that 3.3DeltaE units were considered as acceptable threshold values. PMID- 29178730 TI - A clinical, randomized, double-blind study on the use of toothpastes immediately after at-home tooth bleaching. AB - PURPOSE: To evaluate the effect of 5% potassium nitrate containing 2% sodium fluoride and 10% strontium chloride on tooth sensitivity and color change after at-home bleaching treatment across 3 months of follow-up. METHODS: 60 subjects were randomly allocated by numerical draw into three groups (n= 20): (1) Control, treated with 22% carbamide peroxide (CP) followed by application of a toothpaste without active ingredient: (2) Nitrate, treated with 22% CP followed by application of a toothpaste containing 5% potassium nitrate and 2% sodium fluoride: (3) Strontium, treated with 22% CP followed by application of a toothpaste containing 10% strontium chloride. An air jet was used to evaluate post-bleaching sensitivity associated with a modified visual analogue scale (VAS). A spectrophotometer was used to measure the color of the maxillary incisors. RESULTS: The Friedman vs Kruskal-Wallis tests showed that the tooth sensitivity associated with the experimental groups during 10 days of bleaching treatment was lower than that reported with the Control (P= 0.043). ANOVA showed that variation in DeltaE revealed no significant difference in tooth color among the groups for the different evaluation times (P= 0.923). CLINICAL SIGNIFICANCE: The use of a toothpaste containing 5% potassium nitrate associated with 22% carbamide peroxide improves symptoms of dentin sensitivity after 10 days of bleaching treatment. PMID- 29178731 TI - Clinical effect of a manual toothbrush with tapered filaments on dental plaque and gingivitis reduction. AB - PURPOSE: To evaluate the anti-plaque efficacy (Study 1) and the anti-gingivitis efficacy (Study 2) of a manual toothbrush with tapered bristles compared to marketed control manual toothbrushes. METHODS: Studies 1 and 2 were independent, randomized and controlled, single-center, examiner-blind clinical trials in generally healthy adults. Study 1 included a 2-day acclimation period, followed by a 5-day twice daily toothbrushing test phase with the assigned brush. Baseline and Day 5 pre- and post-brushing plaque levels were assessed via Turesky Modified Quigley-Hein Plaque Index (TMQHPI). In Study 2, subjects with existing gingivitis brushed with their assigned toothbrush twice daily for 4 weeks. Gingivitis was measured using the Mazza Modification of the Papillary Bleeding Index at Baseline and Weeks 2 and 4. In both trials, subjects were randomly assigned to either the manual toothbrush with tapered bristles (Oral-B Super Thin Indicator toothbrush, OM159) or the marketed control (Study 1: Oral-B Complete Clean & Sensitive toothbrush; Study 2: Crest Pro-Health Complete 7 Brush 35 toothbrush) for use with a regular fluoridated dentifrice. RESULTS: 40 (Study 1) and 63 (Study 2) subjects were randomized in each trial. In Study 1, both the tapered bristle and marketed control brushes provided significant (P< 0.0001) mean whole mouth plaque reductions at Day 1 and Day 5 post-brushing relative to pre-brushing as measured via TMQPHI, with no between-brush significant differences. Both groups showed a significant reduction in Day 5 post-brushing mean plaque scores versus Day 1 pre- brushing mean plaque scores (P< 0.0001), but the reductions were not significantly different between groups (P= 0.4274). In Study 2, both the tapered bristle brush and the marketed control brush produced significant (P< 0.0001) reductions in both gingivitis and number of gingival bleeding sites at both Weeks 2 and 4 versus baseline. At Week 4, the tapered filament toothbrush group showed 8.6% less gingivitis (P= 0.0017) and 33.4% fewer bleeding sites (P= 0.0030) versus the control brush. All toothbrushes were well-tolerated. CLINICAL SIGNIFICANCE: Twice daily customary use of a manual toothbrush with tapered bristles provided clinically meaningful plaque and gingivitis reduction benefits. PMID- 29178732 TI - Comparison of enamel bond fatigue durability of universal adhesives and two-step self-etch adhesives in self-etch mode. AB - PURPOSE: To comparatively evaluate universal adhesives and two-step self-etch adhesives for enamel bond fatigue durability in self-etch mode. METHODS: Three universal adhesives (Clearfil Universal Bond; G-Premio Bond; Scotchbond Universal Adhesive) and three two-step self-etch adhesives (Clearfil SE Bond; Clearfil SE Bond 2; OptiBond XTR) were used. The initial shear bond strength and shear fatigue strength of the adhesive to enamel in self-etch mode were determined. RESULTS: The initial shear bond strengths of the universal adhesives to enamel in self-etch mode was significantly lower than those of two-step self-etch adhesives and initial shear bond strengths were not influenced by type of adhesive in each adhesive category. The shear fatigue strengths of universal adhesives to enamel in self-etch mode were significantly lower than that of Clearfil SE Bond and Clearfil SE Bond 2, but similar to that OptiBond XTR. Unlike two-step self-etch adhesives, the initial shear bond strength and shear fatigue strength of universal adhesives to enamel in self-etch mode was not influenced by the type of adhesive. CLINICAL SIGNIFICANCE: This laboratory study showed that the enamel bond fatigue durability of universal adhesives was lower than Clearfil SE Bond and Clearfil SE Bond 2, similar to Optibond XTR, and was not influenced by type of adhesive, unlike two-step self-etch adhesives. PMID- 29178733 TI - The role of adhesive materials and oral biofilm in the failure of adhesive resin restorations. AB - PURPOSE: To critically discuss adhesive materials and oral cariogenic biofilm in terms of their potential relevance to the failures of adhesive restorations in the oral environment. METHODS: The literature regarding adhesive restoration failures was reviewed with particular emphasis on the chemistry of adhesive resins, weakness in dentin bonding, water fluids, cariogenic oral biofilm and the relations that influence failures. Particular attention was paid to evidence derived from clinical studies. RESULTS: There was much evidence that polymerization shrinkage is one of the main drawbacks of composite formulations. Stress results in debonding and marginal leakage into gaps with deleterious effects in bond strength, mechanical properties and the whole stability of restorations. Changes in resins permit passage of fluids and salivary proteins with a biological breakdown of the restorations. Esterases enzymes in human saliva catalyze exposed ester groups in composite producing monomer by-products, which can favor biofilm accumulation and secondary caries. Adhesive systems may not produce a dense hybrid layer in dentin. Very often this is related to the high viscous solubility and low wettability in dentin of the hydrophobic BisGMA monomer. Thus, dentin hybrid layer may suffer from hydrolysis using both the Etch&Rinse and Self-Etching adhesive systems. In addition, exposed and non-resin enveloped collagen fibers may be degraded by activation of the host-derived matrix metalloproteinase. Plaque accumulation is significantly influenced by the surface properties of the restorations. Biofilm at the contraction gap has demonstrated increased growth of Streptococcus mutans motivated by the chemical hydrolysis of the adhesive monomers at the margins. Streptococcus mutans is able to utilize some polysaccharides from the biofilm to increase the amount of acid in dental plaque with an increase in virulence and destruction of restorations. Stability of resin restorations in the oral environment is highly dependent on the structure of the monomers used in composite and adhesive systems. Still, the issues related to microleakage of fluids into the gap and bacteria leaching from the surface of composites represent the main causes of failure of adhesive restorations. CLINICAL SIGNIFICANCE: Modifications of adhesive materials are necessary to address their instability in the oral environment. PMID- 29178734 TI - NaF rinse and dentifrice concentrations on enamel lesion demineralization. AB - PURPOSE: To compare the in vitro effectiveness of two mouthrinses containing different concentrations of NaF to reduce enamel lesion demineralization. METHODS: Nine extracted caries-free molars were selected and cleaned. The teeth were painted with acid resistant varnish, leaving a 1 mm * 4 mm window exposed. The teeth were cycled in a demineralizing solution at pH 4.5 for a total for 96 hours. The teeth were sectioned longitudinally through the unpainted window using a hard-tissue microtome, producing 96 sections. The sections were measured and photographed under polarized light microscopy using water and Thoulet's 1.47 as imbibing mediums. Six treatment groups were randomly created: (A) water control group, (B) 0.05% rinse group once a day (C) 0.02% rinse group twice a day, (D) 1,500 ppm paste group used twice a day, (E) combination group containing 0.05% rinse once a day, and 1,500 ppm paste twice a day, and (F) combination group containing 0.02% rinse and 1,500 ppm paste twice a day. A 10-day cycling protocol was carried out. All sections were then re-measured and re-photographed. A statistical analysis was performed to detect any differences between pre- and post-treatment groups. RESULTS: There was a statistically significant difference in lesion depth between the water control group and the 1,500 ppm paste group as well as the 0.05% rinse in combination with 1,500 ppm paste group (P= 0.0184). No statistically significant differences were found between the control group and any other groups. A statistically significant difference was found in lesion area between the two rinse groups alone and the 1,500 ppm paste group, as well as the 0.05% rinse in combination with the 1,500 ppm paste group (P= 0.0002). An analysis of the results suggested that both rinse concentrations performed equally well in reducing lesion demineralization when used alone. However, only the 0.05% rinse used in combination with 1,500 ppm paste decreased lesion demineralization as compared to the water control group, and was equally as effective as the 1,500 ppm paste alone. CLINICAL SIGNIFICANCE: Within the limitations of this in vitro study, it was found that a fluoride containing dentifrice (1,500 ppm) and a combination of a fluoride containing dentifrice (1,500 ppm) and a 0.05% (210 ppm) fluoride rinse were more effective at reducing demineralization of enamel lesions than sodium fluoride rinses at concentrations of 0.02% and 0.05% alone or the combination of 0.02% NaF rinse with fluoride toothpaste. PMID- 29178735 TI - Silver diamine fluoride, potassium iodide, and esthetic perception: An in vitro pilot study. AB - PURPOSE: To assess if there was a perceptible difference in staining of restorations in silver diamine fluoride (SDF)-treated teeth, with or without the subsequent application of potassium iodide (KI). METHODS: 20 extracted teeth with frank cavitated carious lesions were prepared with a spoon excavator to remove superficial soft carious dentin and then randomly divided into two groups of 10. The control group was treated with 38% SDF and then restored with glass-ionomer. The experimental group received similar treatment, with the additional step of KI applied before restoration. All teeth were subjected to 500 thermocycles between 5 degrees C and 55 degrees C, followed by storage in artificial saliva at 37 degrees C for 30 days. Three blinded examiners evaluated all 20 teeth for intensity of staining on a scale from 0-5. Wilcoxon rank sum test compared average staining intensity between control and experimental groups of teeth as perceived by each examiner. RESULTS: No significant differences were found (P values: 0.93, 0.67, and 0.97). An aggregate comparison of staining perception between control and experimental groups by repeated measure analysis was done treating the outcome as Poisson distribution also finding no significant difference (P= 0.82). CLINICAL SIGNIFICANCE: The application of potassium iodide after silver diamine fluoride on caries-affected teeth may improve initial esthetic appearance, but after placement of a glass ionomer restoration, potassium iodide does not seem to result in any significant difference in staining. PMID- 29178736 TI - Comparison of dental bleaching effects of ozone and hydrogen peroxide: An ex vivo study. AB - PURPOSE: To compare the efficacy of using ozone versus hydrogen peroxide (H2O2) for tooth bleaching. METHODS: 90 extracted teeth were allocated into two groups. Teeth in Group 1 (n= 45) were exposed to ozone for 60 seconds; ozone was produced by healOzone x4 machine (healOzone x4), and was applied to teeth through special disposable silicone cups. The silicone cups allowed total seal and avoided gas escape as the machine is devised to work only if the cup guarantees perfect seal and thus secure the safety of the machine for human use. Teeth in Group 2 (n= 45) were treated with 38% H2O2 for 20 minutes. The shade of teeth was recorded for both groups at base line, after application of ozone in Group 1, and after application of H2O2 in Group 2. The reading for L* a* b* values and Vita Classic shades were recorded using the Colorimeter Konica-Minolta CR-400. The statistically significant differences were set at P<= 0.05. RESULTS: The teeth in both groups acquired lighter shades after bleaching (P< 0.001). In addition, baseline L* shade values were increased and b* shade values were decreased (means lighter shades) after bleaching in both groups (P< 0.01). However, baseline a* shade values were not significantly changed after bleaching with ozone in Group 1 (P= 0.682). In contrast, a* shade values were significantly decreased after bleaching with H2O2 in Group 2 (P= 0.005). Furthermore, final shades achieved after bleaching were not significantly different between groups (P> 0.05). In conclusion, application of ozone for 60 seconds or application of 38% of H2O2 for 20 minutes resulted in teeth with lighter shades. Bleaching by application of ozone for 60 seconds would result in similar outcomes to bleaching with 38% H2O2. CLINICAL SIGNIFICANCE: This is the first study to compare bleaching effects of ozone and hydrogen peroxide on natural human teeth. It might be suitable to consider ozone for dental bleaching since comparing to H2O2 it could potentially reduce the time, side effects and cost of treatment. Also, application of ozone is better controlled and more convenient and measurable as it is delivered by a machine that can manage the concentration, volume, delivery site and timing of delivered ozone. PMID- 29178737 TI - Effect of resin cement, aging process, and root level on the bond strength of fiber-posts: An in vitro study. AB - PURPOSE: To compare the push-out bond strength (POBS) of two resin cement systems (total-etch versus self-etch) for cementing FRC (fiber-reinforced composite) posts in three different thermocycling aging periods (40,000; 20,000; and none) using thermocycling and three root levels (apical, middle, and coronal). METHODS: 60 bicuspid single rooted natural teeth were endodontically treated and post spaces were prepared to receive a fiber-post (RelyX FiberPost) cemented with either total-etch (RelyX Ultimate) or self-etch (RelyX Unicem) cement. Teeth were randomly allocated into six groups (n= 10): G1: Control (Ultimate without thermocycling); G2: Ultimate (20,000 cycles); G3: Ultimate (40,000 cycles); G4: Unicem without thermocycling; G5: Unicem (20,000 cycles); and G6: Unicem (40,000 cycles). POBS was determined by using a push-out test on a universal testing machine. Additionally, failure mode of each specimen was observed under a stereomicroscope at x40 magnification and scanning electron microscope (SEM) examination of selected samples. A nested general linear model was created for statistical significance P< 0.05. Post-hoc tests were carried out using pair-wise comparisons with a Bonferroni adjustment. RESULTS: No significant differences were found on the bond strengths between the resin cements (P= 0.856). Regarding aging effect, bond strengths of the 40,000 cycle groups (G3/G6) were significantly lower than 20,000 cycle groups (G2/G5). In addition, the POBS of the specimens collected from the coronal third of the roots were significantly lower than specimens from the apical third regardless of the type of cement used. Regarding types of failures, adhesive failure (post/cement) was significantly higher in total-etch groups (G1-G3) than the self-etch groups (G4-G6). Adhesive failure (dentin/cement) was significantly higher in self-etch groups than the total-etch groups. CLINICAL SIGNIFICANCE: Within the limitations of this study, the bond strength to root canal dentin of self-etch and total-etch cements demonstrated reliable results and was not affected by the type of resin cement. Simplification of technique is an evident advantage of these materials in clinical practice. PMID- 29178739 TI - The effects of overhang amalgam restoration on levels of cytokines, gingival crevicular fluid volume and some periodontal parameters. AB - PURPOSE: To evaluate clinical periodontal findings and GCF levels of tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6) and interleukin 8 (IL-8) in patients with overhang amalgam restorations before and after overhang restoration removal. METHODS: 22 volunteer subjects (age range: 22-42 years old) with 22 overhang Class II amalgam restorations were selected. GCF samples were obtained from adjacent and contralateral teeth for IL-6, IL-8 and TNF-alpha measurements and analyzed using enzyme-linked immunosorbent assay (ELISA) kits. The amalgam overhangs were removed and the readings were repeated at the end of 1 week. Clinical periodontal assessments, including gingival index (GI) and plaque index (PI) were performed at baseline and after 1 week. Data were analyzed using the paired t-test and independent sample t-test at a significance level of 0.05. Correlations were investigated using Pearson correlation analysis. RESULTS: A significant reduction in GI and PI was observed after removal of the overhanging restoration on Day 7. (P< 0.05) However, there was no significant difference between IL-6 (P= 0.857), IL-8 (P= 0.579) and TNF-alpha (P= 0.958) levels before and after overhang restoration removal. There were no significant correlations between laboratory findings and clinical parameters. CLINICAL SIGNIFICANCE: Dental restorations may produce periodontal disease and may alter tooth form, surface integrity, relationship with the periodontium and adjacent teeth. The marginal edge located in the gingival sulcus is likely the cause of the inflammatory reaction. This study showed significant improvement in clinical periodontal parameters after removing the overhangs of restorations. PMID- 29178738 TI - Salivary IL-6 and IL-10 levels in subjects with obesity and gingivitis. AB - PURPOSE: To evaluate the association between cytokines IL-6 and IL-10 in saliva, obesity and periodontal disease. METHODS: The study was carried out in 40 subjects: 20 obese subjects with gingivitis and 20 non-obese subjects with gingivitis (controls). Periodontal parameters such as gingival index (GI) and plaque index (PI) of subjects were recorded. Saliva samples were used for measuring IL-6 and IL-10 levels by ELISA method. RESULTS: Saliva IL-6 levels were significantly higher in obese subjects than those of non-obese subjects (P= 0.002). When total groups were evaluated, negative significant correlation between GI and salivary IL-10 levels (r= -0.452, P= 0.003) and positive correlations between salivary IL-6 level and body mass index (BMI) (r= 0.369, P= 0.019) were found. There was a negative correlation between the GI and salivary IL-10 levels in obese subjects (r= -0.548, P= 0.012). Also there was a positive correlation between the salivary level of IL-6 and IL-10 in obese subjects (r= 0.594, P= 0.006). CLINICAL SIGNIFICANCE: Obesity and adipose tissues can affect periodontal health by altering the levels of IL-6 and IL-10. IL-6 in saliva clearly increased in subjects with obesity compared to subjects without obesity. Also negative correlations between saliva IL-10 levels and GI were found in the total group and obese subjects. PMID- 29178740 TI - Dentin hypersensitivity reduction using an arginine-based approach after non surgical periodontal treatment. AB - PURPOSE: To determine the efficacy of two oral hygiene regimens in the reduction of dentin hypersensitivity (DH) on subjects undergoing non-surgical periodontal treatment (NST), over a period of 8 weeks. METHODS: 60 subjects that were randomly assigned to: Test group - NST followed in-office application of an arginine-based professional paste and toothbrushing with arginine-based toothpaste at home (n= 30) and Control group - NST followed in-office application of a fluoride-free prophylaxis paste and toothbrushing with a toothpaste based on sodium monofluorophosphate 0.76%, at home (n= 30). Air blast sensitivity assessments were made using the Schiff scale. The sensitivity parameters were measured at baseline, 1, 4 and 8 weeks. RESULTS: After 1 week, DH reduction was statistically significant for the test group (63.6%) compared to baseline, while no significant reduction was observed for the Control group (4.8%). After 4-8 weeks, the reductions were 81.6%/86.3% for the test group and 9.5%/14.2% for the Control group. When comparing the two groups, the test group showed a superior DH reduction in all evaluation periods (P< 0.05). Within the limits of the present study, it was concluded that the test oral hygiene regimen can effectively reduce dentin hypersensitivity during the most critical period after non-surgical periodontal treatment (up to 8 weeks). CLINICAL SIGNIFICANCE: The arginine-based approach provided significantly greater dentin hypersensitivity (DH) relief after non-surgical periodontal treatment (NST) when compared to the control. The combination of the in-office paste application with the daily used toothpaste may be a useful tool to reduce DH, an unpleasant and common condition that affects a large number of subjects, particularly during the initial weeks following NST. PMID- 29178741 TI - Analysis of the biofilm formed on the surface of a glass-ionomer cement associated with different concentrations of chlorhexidine diacetate. AB - PURPOSE: This cross-over in situ experiment evaluated the microbial composition and quantified the total polysaccharides in the biofilm formed on the surface of a high viscosity glass-ionomer cement (GIC) mixed with chlorhexidine diacetate (CHX) in concentrations of 0.5%, 1% and 2%. GIC without CHX was used as control. METHODS: The volunteers (n= 8) tested each material for a 7-day period, by using a palatal acrylic device containing four round specimens, all fabricated with the same material. An increasing order of CHX concentration and a 15-day washout period between each concentration was adopted. The biofilm formed was collected and inoculated in specific culture media and thereafter, the total microorganisms, total streptococci, Streptococcus mutans and Lactobacillus spp were counted. Total polysaccharides were quantified by using a phenol-sulfuric method. Microbiologic data were analyzed by ANOVA for repeated measures and Tukey tests, and the total polysaccharide content by Friedman and Dunn's tests. Significance level was set at 5%. RESULTS: Microorganism counts showed statistically significant differences among groups only for Lactobacillus (P< 0.05), that were significantly higher for group GIC+CHX 2% compared with GIC and GIC+CHX 0.5%. However, the concentration of total polysaccharides in the biofilm was lower for groups containing 1% and 2% of CHX. CLINICAL SIGNIFICANCE: The addition of chlorhexidine in the studied concentrations did not reduce the microorganism counts, but caused reduction of biofilm density. PMID- 29178742 TI - The influence of two different curing regimens on light energy transmission through bulk-fill resin composites and Vickers hardness. AB - PURPOSE: To compare the total light energy transmission (J/cm2) through bulk-fill composite materials (BFMs) and Vickers hardness (VH) using a single-peak light curing unit (LCU) using two curing regimens. METHODS: Samples (n= 5) of viscous BFMs, Tetric EvoCeram Bulk Fill (TBF), X-tra fil (XF), and flowable BFMs, SureFil SDR (SDR), and X-tra base (XB) were prepared in 4 mm deep rings. The control was Tetric EvoCeram (TEC), a conventional composite. Using MARC-RC, the irradiance delivered to the top surface of the samples was adjusted to either 800 mW/cm2 for 20 seconds (16 J/cm2) or 1,600 mW/cm2 for 10 seconds (16 J/cm2). Samples were stored post-irradiation at 22 +/- 2 degrees C for 24 hours. Top and bottom surface VH were measured and Bottom/Top (B/T) VH ratios were calculated. Data were analyzed using one-way ANOVA (alpha= 0.05). RESULTS: Total energy transmission for all materials ranged from 1.0 J/cm2 (6.1%) to 2.7 J/cm2 (16.9%). There was a statistically significant difference for total energy transmission to the bottom surface, more being transmitted at 800 mW/cm2 x 20 (P< 0.001). XB and TEC were significantly different, with higher B/T VH ratio when cured at 800 mW/cm2 x 20 seconds (P< 0.001). There was no statistically significant difference for TBF, XF and SDR (P> 0.05) with either curing regimen. CLINICAL SIGNIFICANCE: The degree of cure was material-dependent and increasing curing time may be more important than LCU tip irradiation values. Manufacturer's recommended total energy regimen may not always be adequate for effective curing. Some bulk-fill materials, containing additional photo-sensitivity to lower wave lengths, may be adequately cured using a single-peak LCU. PMID- 29178743 TI - Influence of de/remineralization of enamel on the tensile bond strength of etch and-rinse and self-etching adhesives. AB - PURPOSE: To evaluate the bonding behavior of resin composite and different adhesives applied to demineralized or remineralized enamel. METHODS: Bovine tooth crowns were polished to prepare a 5 mm2 enamel bonding area, and divided into five groups (n= 48) according to the surface treatment: CONT (sound enamel control), DEM (demineralized with acid to create white spot lesions), REMS (DEM remineralized with artificial saliva), REMF (DEM remineralized with sodium fluoride) and INF (DEM infiltrated with Icon resin infiltrant). The surface treated teeth were divided into two subgroups (n= 24) according to adhesive type: ER (etch-and-rinse; Single Bond Universal) and SE (self-etching; Clearfill S3 Bond), and further subdivided into two categories (n= 12) according to aging process: Thermo (thermocycling) and NA (no aging). Composite blocks were made over bonded enamel and sectioned for microtensile bond strength (MTBS) testing. Data were analyzed with three-way ANOVA and post-hoc Tukey's test (alpha= 0.05). RESULTS: Significant differences were observed for enamel surface treatment (P< 0.0001), adhesive type (P< 0.0001) and aging (P< 0.0001). CONT and INF groups had higher MTBS than the other groups; Single Bond Universal had higher MTBS than Clearfil S3 Bond; thermo-aging resulted in lower MTBS irrespective of adhesive type and surface treatment condition. The predominant failure mode was mixed for all groups. Enamel surface infiltrated with Icon does not interfere with adhesive resin bonding procedures. CLINICAL SIGNIFICANCE: Treatment of enamel surface containing white spot lesions or cavities with cavosurface margins in partially demineralized enamel can benefit from infiltration with a low viscosity resin infiltrant prior to adhesive bonding of resin composites.

AB - PURPOSE: To evaluate the presence and length of microcracks in resin-based materials finished with different techniques, using optical coherence tomography (OCT). METHODS: Standardized Class V preparations (3x2x2mm) were made in the facial and lingual surfaces of 20 recently-extracted human third molars. 20 preparations were restored with a resin-based composite material (RBC; Filtek Supreme Ultra) and the other 20 with a resin-modified glass-ionomer material (RMGI; Ketac Nano). After final polymerization, specimens were further stratified by finishing system: aluminum oxide discs (Sof-Lex) or spiral fluted carbide bur series (H48L). By random allocation, each extracted tooth therefore received one RBC and one RMGI restoration, and equal numbers of restorations from each material were finished using each finishing system (n= 10). After 24 hours of storage in 100% humidity at room temperature, the specimens were evaluated at x20 to x600 under environmental SEM. Cross-sectional occlusal-cervical B-mode images were obtained in increments of 25 mm from the mesial margin to the distal margin of the restoration using a spectral-domain (SD) OCT system and analyzed using Image J software to identify and measure microcrack penetration into each restoration. The total length (mm) at the point of the deepest microcrack penetration in each specimen was recorded. Data were statistically analyzed using a t-test. RESULTS: No microcracks were observed in the RBC samples. However, microcrack presence was identified in all of the RMGI specimens. The t-test showed a statistically significant difference (P< 0.05) in mean microcrack length values based on the finishing technique used for the RMGI samples. [SofLex: 0.67 (+/- 0.28) mm; carbide: 1.26 (+/- 0.30)] mm. Two-way ANOVA showed significant differences in the factors "finishing technique" and "restorative material" (P< 0.001). The interaction of these two factors was also statistically significant (P< 0.001). For the tested RMGI, Tukey post-hoc test revealed that the finishing with aluminum oxide groups resulted in statistically significant lower mean microcrack length when compared to spiral fluted carbide burs (P< 0.001). CLINICAL SIGNIFICANCE: Resin-modified glass-ionomer (RMGI) is more susceptible to microcrack presence than resin-based composites. Also, aluminum oxide discs produced lower values of mean microcrack length than spiral fluted carbide burs after the finishing procedure of RMGI restorations. PMID- 29178745 TI - Clinical performance of bonded ceramic inlays/onlays: A 5- to 18-year retrospective longitudinal study. AB - PURPOSE: This retrospective longitudinal study evaluated the clinical performance of bonded ceramic inlays/onlays, placed by the first author in his private practice, in a 5 to 18-year period. METHODS: The patients evaluated had been treated in the office for at least 7 years and were still in the practice up to year 2013. 130 randomly selected patients agreed to participate in the study. 93 bonded ceramic inlays/onlays (BCRs), were placed on posterior teeth in 47 subjects. Gender, age, tooth preparation, number, type, extent, location, quality and survival of the restorations, ceramic materials, luting resins cements, parafunctional habits, secondary caries and maintenance therapy were the variables evaluated. Cohen 's Kappa coefficient, on the quality analysis of the restorations, ranged from 0.78 to 1. Fisher 's exact test, Chi Square test, Kruskal-Wallis test and Mann-Whitney non-parametric test were indicated to analyze significant differences. RESULTS: At the initial examination, 87 (93.5%) restorations were in function and six failed (6.5%). 81 (93%) were rated as clinical successes. The observed mean survival time of those that remained functional was 11 years. The standard deviation was 4 years, with a 95% CI for the overall observed mean survival time (10 years-11 years, 9 months). 87 of 93 BCRs had a functional success of 93.5%, with an observed mean survival of 11 years. The clinical performance of bonded ceramic onlays was very acceptable. CLINICAL SIGNIFICANCE: Bonded ceramic onlays showed a predictable, esthetic, and functional treatment, with acceptable longevity. PMID- 29178746 TI - A randomized 3-month clinical comparison of a power toothbrush to a manual toothbrush in the reduction of gingivitis. AB - PURPOSE: To compare the anti-gingivitis effect of a power toothbrush relative to a manual toothbrush control. METHODS: This was a 3-month, randomized and controlled, single-center, parallel group, examiner-blinded clinical study. 123 Chinese adults in good general health and with at least 15 gingival bleeding sites, as measured by the Gingival Bleeding Index, were enrolled into the study. At baseline, pre-treatment gingivitis levels were assessed using the Mazza Bleeding Index. Subjects were then randomly assigned to receive either an oscillating-rotating power toothbrush [Oral-B Professional Care 7000 (D17u/EB17)] or a flat-trim manual toothbrush with tapered filaments (Lion Dentor Systema). Subjects brushed at home twice-daily with their assigned toothbrush and a marketed sodium fluoride dentifrice (Crest Cavity Protection dentifrice), and were reevaluated at Months 1, 2, and 3. RESULTS: 113 evaluable subjects completed the study. Both groups showed significant reductions in gingivitis from baseline for all time points measured (P< 0.001). At Months 1, 2 and 3, the power toothbrush demonstrated significantly greater gingivitis reductions of 7.11%, 9.20% and 8.47%, respectively, than the manual toothbrush (P< 0.01), and significantly fewer bleeding sites (17.3%, 23.9% and 24.3%, respectively, P< 0.05). No adverse events were reported or observed for either brush during the study. CLINICAL SIGNIFICANCE: The power brush provided statistically significantly greater reductions in gingivitis compared with a manual toothbrush at Months 1, 2 and 3. PMID- 29178747 TI - Correlation among periodontal health status, maternal age and pre-term low birth weight. AB - PURPOSE: To assess correlations between periodontal status, maternal age and adverse pregnancy outcomes, such as pre-term and low birth weight in a sample of pregnant women. METHODS: Study population was represented by outpatient pregnant women, gestational age > 26 weeks. Medical history questionnaires were administered to all participants who underwent clinical evaluation; clinical obstetric outcome records were collected after delivery. A questionnaire was administered regarding personal information, socio-economic status, oral hygiene habits, and oral health conditions. A clinical oral examination was performed to collect Simplified Oral Hygiene Index (OHI-S) and Community Periodontal Index (CPI). Pregnancy outcome records included: delivery week, kind and causes of delivery, any relevant complications, and birth weight. Descriptive statistics were used to depict the data from the questionnaire while the relationship between delivery week, birth weight, maternal age and periodontal status was evaluated through multivariate tests of significance. RESULTS: 88 pregnant women were enrolled in the study. The results showed a statistically significant correlation (P< 0.001) among participants older than 40 years of age, between periodontal disease and adverse pregnancy outcomes. No statistical correlation was found among pre-term and low birth weight, smoking, ethnicity and educational level of mothers. The results highlight the importance of including a routine oral and periodontal health examination in pregnant women older than 40 years of age. CLINICAL SIGNIFICANCE: The correlation between periodontal status and adverse pregnancy outcomes in older mothers indicates the need for routine oral health examination and periodontal status assessment and care in pregnant women older than 40 years of age. PMID- 29178748 TI - Direct pulp capping versus root canal treatment in young permanent vital teeth with pulp exposure due to caries. A systematic review. AB - PURPOSE: To evaluate the available evidence on pulp capping procedures and root canal treatment in young permanent teeth with vital pulps exposed by caries. METHODS: The study was conducted as a systematic review of the literature. Three databases, PubMed, Web of Knowledge, and The Cochrane Library were searched. Reference lists of relevant articles were hand searched. The quality of all relevant publications was rated. RESULTS: Ten original scientific studies were included in the review. The quality was rated as low in all studies. The search failed to disclose any article directly comparing pulp capping and root canal treatment. The level of evidence was insufficient to draw any conclusions regarding the effectiveness of the two treatment concepts. High success rates are reported for pulp capping procedures in exposure due to caries, though it is not possible to compare them to success rates of root canal treatment. The review confirms the lack of high quality studies on the treatment of young permanent teeth with cariously exposed pulps. CLINICAL SIGNIFICANCE: For the treatment of young permanent teeth with pulp exposure due to caries there is currently no evidence to support the assumption on pulp capping being more beneficial than root canal treatment in achieving a symptom free tooth with normal periapical conditions. PMID- 29178749 TI - Effects of carbodiimide dentin surface treatment on resin-dentin bonding. AB - PURPOSE: To assess the effects of ethanol-based 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide (EDC) dentin surface treatment on resin-dentin bonding and dentin collagen fibril biodegradation. METHODS: Acid-etched dentin surfaces were pretreated with different concentrations of ethanol-based EDC solutions (0.01-2M) for 60 seconds, followed by two-step etch-and-rinse dentin adhesive application and resin composite bonding. Dentin surfaces pretreated with either ethanol alone or no pretreatment were used as controls. The specimens were subjected to microtensile bond strength testing after storage in 0.9% NaCl solution at 37 degrees C for either 24 hours or 90 days. Furthermore, demineralized dentin slabs with and without ethanol-based EDC pretreatment were exposed to a collagenase solution for 24 hours, and subsequent hydroxyproline release was measured using ELISA. Data were analyzed with ANOVA and multiple comparison tests at alpha= 0.05. RESULTS: The bond strength values were significantly lower for dentin surfaces pretreated with 1 and 2 M ethanol-based EDC than for the control surfaces (P< 0.05). The 0.01, 0.1, and 0.3 M ethanol based EDC pretreated groups obtained significantly higher bond strength values at 90 days compared to controls. Hydroxyproline release measurements revealed that there were significantly lower levels released in the 0.3 and 1 M ethanol-based EDC pretreated specimens than for controls (P< 0.05). CLINICAL SIGNIFICANCE: Pretreatment of dentin surfaces with ethanol-based EDC solution <= 0.3M before resin composite bonding can improve the stability of the resin-dentin bond and prevent dentin collagen fibril biodegradation. PMID- 29178750 TI - Efficacy of a new filler-containing root coating material for dentin remineralization. AB - PURPOSE: To evaluate a new root coating material containing surface pre-reacted glass-ionomer (S-PRG) filler for remineralization of demineralized dentin. METHODS: The dentin was exposed on root surfaces of human third molars and demineralized by immersion in demineralization solution for 4 days. The demineralized dentin surface was divided into three areas. The center area was left untreated. The area on one side of the center area was coated with protective wax. The area on the other side was coated with one of four test materials: fluoride-containing S-PRG filler (PRG Barrier Coat: PR), fluoride containing bonding agent (Bond Force: BF), fluoride-containing glass-ionomer cement as a positive control (Fuji IX EXTRA: EX), or non-fluoride-containing bonding agent as a negative control (Clearfil MegaBond: MB). The samples were stored in remineralization solution for 7 days, and then cut into two slices. The mineral changes, defined as variation in mineral loss between wax-coated area and the central untreated area, were measured in one slice by transversal microradiography. The fluoride concentration was measured in the other slice by u particle-induced gamma/X-ray emission. Seven thin specimens (0.25-mm thickness) of each test material were used to determine fluoride ion release from the materials over 21 days. RESULTS: The mineral changes were greatest for EX, followed by PR, with no difference between BF and MB (P> 0.05). Regarding the fluoride concentrations in dentin, there was no difference between EX and PR (P> 0.05). MB had the lowest value (P< 0.01). Fluoride release from EX was largest, followed by PR, with BF showing low fluoride release (P< 0.05). MB had no fluoride release. CLINICAL SIGNIFICANCE: A new coating material with S-PRG filler can be applied in a thin layer on root dentin, which could be especially useful for hard-to-access lesions. This material remineralized demineralized root dentin and had fluoride diffusion characteristics similar to those of glass-ionomer cement in vitro. PMID- 29178751 TI - Cytogenetic damage in exfoliated oral buccal cells by dental composites. AB - PURPOSE: To evaluate the possible geno/cytotoxic effects of dental composite materials by assessing the frequency of micronuclei formation and other nuclear abnormalities in the exfoliated buccal epithelium. METHODS: Swabs were taken from the buccal mucosa of 85 young healthy subjects. All participants had healthy dentition or dentition restored only with composite materials. Genotoxicity and cytotoxicity was assessed by micronucleus assay. RESULTS: The results indicated no significant difference in number of oral mucosa cells with micronuclei in subjects with different numbers of composite restored tooth surfaces (P= 0.476). Also, the number of restored surfaces had no effect on nuclear alterations closely related to cytotoxicity, such as karyolysis (P= 0.572), karyorrehexis (P= 0.573) and picnosis (P= 0.765). CLINICAL SIGNIFICANCE: Despite doubts about the safe clinical use of resin composites, this study found no evidence that composite materials trigger long-term cytogenetic damage in the epithelial cells of buccal mucosa in humans. There is no objective and quantifiable evidence of genotoxicity induced by composite restorative materials in clinical practice. PMID- 29178752 TI - Fiber optics reflectance spectroscopy (45 degrees x: 45 degrees ) for color analysis of dental composite. AB - PURPOSE: To evaluate the application of a fiber optic reflectance spectroscopy (FORS) prototype probe for 45 degrees x: 45 degrees FORS for determining color of dental materials. A portable spectrophotometer with a highly manageable fiber optics co-axial probe was used to apply 45 degrees x: 45 degrees FORS for color matching in restorative dentistry. METHODS: The color coordinates in CIELAB space of two dental shade guides and of the corresponding photopolymerized composites were collected and compared. The 45 degrees x: 45 degrees FORS with the co-axial probe (test system), the integrating sphere spectroscopy (reference system) and a commercial dental colorimeter (comparator system) were used to collect data and calculate color differences (DeltaE and DeltaE00). RESULTS: FORS system displayed high repeatability, reproducibility and accuracy. DeltaE and DeltaE00 values between the shade-guide, each other, and the corresponding composites resulted above the clinically acceptable limit. The 45 degrees x: 45 degrees FORS test system demonstrated suitable in vitro performance for dental composite color evaluation. CLINICAL SIGNIFICANCE: 45 degrees x: 45 degrees fiber optic reflectance spectroscopy allows reliable color analysis of small surfaces of dental composites, favoring the color matching of material with the closely surrounding dental tissue, and confirming significant color differences between shade guide tabs and photo-polymerized composites. PMID- 29178753 TI - Detection of occlusal caries with impedance spectroscopy and laser fluorescence before and after placement of fissure sealants: An in vitro study. AB - PURPOSE: To (1) investigate the influence of fissure sealants on impedance spectroscopy (ACIS) and laser fluorescence (LF) readings, (2) compare the performance of the ACIS device with the LF technique and visual inspection (ICDAS) in permanent molars with various degrees of occlusal caries, and (3) validate all methods against radiographs and histological hemi-sectioning. METHODS: 102 permanent molars were randomly selected to represent different stages of occlusal caries, from clinically sound to minor cavities. The teeth were examined by one trained examiner and scored with CarieScan PRO, the DIAGNOdent pen and ICDAS at baseline, after bleaching, etching and placement of a clear fissure sealant. A digital radiograph was exposed at baseline. After the assessments, the actual lesion depth was histologically determined. RESULTS: Bleaching did not affect the readings but significantly higher ACIS and LF-pen values were recorded after acid etching (P< 0.05). The placement of a fissure sealant increased the LF-pen readings significantly (P< 0.05) while no values could be obtained with the ACIS device. Both the baseline ACIS and LF-pen values were significantly associated (P< 0.05) with the lesion depth but visual inspection displayed the best correlation with radiographs and histology. The ACIS technology displayed high sensitivity and specificity for detecting extensive occlusal lesions. CLINICAL SIGNIFICANCE: The findings demonstrated that placement of a fissure sealant had a significant impact on the ACIS and LF-pen readings. Both methods mirrored the actual histological and radiographic lesion depth to various extents but could not match the performance of visual inspection. PMID- 29178754 TI - Heat generated during light-curing of restorative composites: Effect of curing light, exotherm, and experiment substrate. AB - PURPOSE: To investigate temperature rise, separating heat caused by irradiation and exotherm for three composites polymerized with three curing lights. The effect of substrate on temperature measurements was also determined. METHODS: Composite samples (n= 5) (Filtek Supreme Ultra, Filtek LS, and EsthetX HD) were placed on a thermocouple tip inside three substrates (aluminum, Delrin, and tooth). The composites were photoactivated using three curing lights (Elipar 2500 QTH, SmartLite Max LED, DemiUltra LED) at 1 mm distance. Irradiance was 798, 980, and 1,135 mW/cm2, respectively. Exotherm was determined by subtracting post-cure from the polymerization temperature curves. ANOVA and Student-Newman-Keuls post hoc tests were used to analyze differences among peak temperatures and exotherms (significance level 0.05). RESULTS: SmartLite LED curing light resulted in higher peak temperatures and exotherms compared to the DemiUltra LED and QTH for all tested composites (16.9-20.4 degrees C vs 12.3-14.7 degrees C vs 8.9-9.7 degrees C). Thus, the LEDs produced higher temperature rises than the QTH, and the LED with lower irradiance caused higher temperature rise than the LED with higher irradiance. The silorane-based Filtek LS generated significantly higher exotherm than the methacrylate-based EsthetX HD and Filtek Supreme Ultra (6.2-7.6 degrees C vs 3.6-4.5 degrees C vs 2.7-3.6 degrees C). Substrate affected temperatures significantly. Temperature profiles found in Delrin substrate were comparable to tooth substrate, while aluminum substrate reduced temperatures 10-20 degrees. CLINICAL SIGNIFICANCE: Curing of restorative composites raises the temperature under a restoration due to irradiation and exothermic reaction; how much the temperature increases depends on curing light design, type of composite, and surrounding substrate. The silorane-based Filtek LS generated significantly higher exotherm than the methacrylate-based EsthetX HD and Filtek Supreme Ultra. PMID- 29178755 TI - Prognosis test by visualization of demineralized dentin under restorations to prevent initial wall-lesions initiated by lactic acid. AB - PURPOSE: To visualize the complete protection of restored dentin in the acidic environment by the complete impregnation of resin into demineralized dentin. METHODS: Class V cavities prepared in extracted human molars composed of enamel, cementum and dentin surfaces were sealed using either 4-META/MMA-TBB resin with conditioning periods of 10, 30, 60 seconds with 10% citric acid and 3% ferric chloride mixed aqueous solution (10-3) or Single-Bond 2 adhesives prior to restoration with light-cured resin-composite. Specimens were either immersed in artificial saliva or 0.1 mol/L buffered lactic acid solutions at 37 degrees C for 14 days. After immersion in 0.5% basic fuchsin dye for 24 hours, the extent of dye penetration at the margin was measured. SEM micrography was used to investigate the quality of hybridized dentin when immersed in HCl followed by NaOCl solutions. RESULTS: After lactic acid exposure, dye penetration into the adjacent demineralized cementum/dentin was found to be significantly lower than the leakage distance under 30 and 60 seconds and Single-Bond 2 specimens. Leakage free margins were found in 10-second conditioning period specimens for both control and after soaking in buffered lactic solution with the stable hybridized dentin after chemical challenge. CLINICAL SIGNIFICANCE: A leakage-free interfacial layer, provided by complete hybrid layer formation, can block lactic acid penetration. Using this novel prognosis test for visualization of demineralized dentin, clinical restorations are likely to be more reliably predictable in the prevention of initial wall-lesions, post-operative hypersensitivity and/or pulpal infection. PMID- 29178756 TI - Porosity of flowable resin composites is not influenced by applicator tip diameter. AB - PURPOSE: To assess the influence of applicator tip diameter on the inclusion of porosities in three different flowable resin composites. METHODS: The initial porosity of three syringes [Filtek Supreme XTE Flowable (XTE), Grandio Flow (GRF), Gradia Direct Flo (GDF)] was determined by 3D tomography. 25 samples per syringe, i.e. 75 samples in total, were prepared using five applicator tips of different diameters (n= 5). The porosity of the 75 samples was assessed by 3D tomography. RESULTS: For each of the materials, the applicator tips, irrespective of type, all generated an increase in the average porosity percentage compared to the initial porosity of the syringes. For XTE and GRF, the applicator tips, irrespective of type, all generated a decrease in the average porosity volume compared to the initial average porosity volume in their respective syringes. Conversely, for GDF the average porosity volume of the samples was increased. Furthermore, for each of the materials, varying the diameter of the applicator tips had no significant influence on the porosity percentage and volume. Using the present study conditions, the applicator tip generated a variation in the initial porosity of the materials; however, the diameter of the tip had no influence on said variation. CLINICAL SIGNIFICANCE: It appears that practitioners can choose an applicator tip with a diameter that best suits the size and shape of the cavity to be filled using a syringe of flowable resin composite without this having any impact on the percentage and volume of porosities in the final filling of the cavity. PMID- 29178757 TI - Clinical and radiographic evaluation of white MTA versus formocresol pulpotomy: A 48-month follow-up study. AB - PURPOSE: To determine whether there were differences between formocresol (FC) and white mineral trioxide aggregate (MTA) pulpotomy in terms of clinical and radiographic signs or effects upon the permanent successor over a long term. METHODS: A total of 212 molars (74 treated with FC and 138 with white MTA) corresponding to 129 subjects [66 females (51.1%) and 63 males (48.8%)] were evaluated. The coronal pulp was carefully amputated up to the entrance of the root canals using a sharp spoon excavator. Post-amputation bleeding was confirmed to be bright red and was seen to subside after applying 2-3 minutes of gentle pressure with a sterile cotton pellet. One group was treated with a 1:5 dilution of formocresol (20% Buckley's formocresol solution), while a second group was treated using white MTA powder (ProRoot). RESULTS: There were no significant differences in clinical success rate between the two groups (89.9% in the white MTA group versus 82.5% if the FC group). However, the radiographic success rate was significantly greater for white MTA versus FC. The radiographic failure rate in the molars treated with MTA was 7.9% versus 18.9% with FC. Regarding alterations in the timing of eruption, early and delayed eruption were respectively recorded in 7.24% and 8.69% of the cases in the MTA group, versus 9.45% and 4.05% of the cases in the FC group. Thus, neither group showed relevant alterations in the timing of eruption. CLINICAL SIGNIFICANCE: Mineral trioxide aggregate showed a significantly greater radiographic success rate than formocresol in pulpotomy in primary teeth over 6 to 48 months of follow-up. MTA may be indicated as a substitute of formocresol in pulpotomy treatments of temporary molars, with no pathological consequences of any kind to the permanent successor premolar. PMID- 29178758 TI - Magnesium hydroxide-based dentifrice as an anti-erosive agent in an in situ intrinsic erosion model. AB - PURPOSE: To evaluate in situ a magnesium hydroxide-[Mg(OH)2] based dentifrice on enamel erosion. METHODS: Human dental enamel slabs were selected by surface microhardness and randomly assigned to one out of the following three groups (n=18): non-fluoride (control), NaF (1,450 ppm F), and Mg(OH)2 dentifrices. 18 volunteers were enrolled in a randomized, crossover and double-blind study, with three phases in 5 days. They wore acrylic palatal appliances containing two human enamel slabs, which were treated with one of the three dentifrices. During each experimental phase, the specimens were subjected to erosion by immersion in 0.01 M HCl for 60 seconds, 4x/day, followed by a 1-minute treatment with the correspondent slurry (saliva/dentifrice). Enamel changes were determined by the percentage of surface hardness loss (%SHL) and mechanical profilometry analysis. Data were analyzed by ANOVA, followed by Tukey's test (P< 0.05). RESULTS: The means (SD) for %SHL and surface wear (MUm) were, respectively, as follows: control [50.67(17.48), 2.70(1.24) ], NaF [45.45(15.44), 1.95(0.70) ] and Mg(OH)2 [53.94(19.48), 1.95(0.67) ]. There was no statistically significant difference among the treated and control groups for %SHL (P= 0.349); however, for wear rates, a statistically significant difference was found between the groups treated with NaF and Mg(OH)2 and the control group (P= 0.04). CLINICAL SIGNIFICANCE: Dentifrices containing magnesium hydroxide or sodium fluoride might be an important strategy to minimize the effects of erosive challenges. PMID- 29178759 TI - The abrasive effect of commercial whitening toothpastes on eroded enamel. AB - PURPOSE: To evaluate the in vitro abrasive effect of commercial whitening toothpastes on eroded bovine enamel samples in respect to erosive tooth wear. METHODS: 72 bovine crowns were embedded, polished and subjected to the baseline profile analysis. The samples were then protected in 2/3 of the enamel surface and were randomly assigned to six groups (n= 12/group): G1: Oral-B 3D White, G2: Close-up Diamond Attraction Power White, G3: Sorriso Xtreme White 4D, G4: Colgate Luminous White, G5: Crest (conventional toothpaste), G6:erosion only (control). All samples were submitted to an erosive pH cycling (4 x 90 seconds in 0.1% citric acid, pH 2.5, per day) and abrasive challenges (2 x 15 seconds, per day) for 7 days. After the first and the last daily cycles, the samples were subjected to abrasive challenges, using a toothbrushing machine, soft toothbrushes and slurry of the tested toothpastes (1.5 N). Between the challenges, the samples were immersed in artificial saliva. The final profile was obtained and overlaid to the baseline profile for the calculation of the erosive tooth wear (MUm). The data were subjected to Kruskal-Wallis/Dunn tests (P< 0.05). RESULTS: G1 promoted the highest enamel wear (3.68+/-1.06 MUm), similarly to G3 (3.17+/- 0.80 MUm) and G4 (3.44+/- 1.29 MUm). G3 and G4 performed similarly between them and compared with G5 (2.35+/- 1.44 MUm). G2 (1.51+/- 0.95 MUm) and G6 (0.85+/- 0.36 MUm) showed the lowest enamel wear, which did not differ between them and from G5. Oral-B 3D White showed the highest abrasive potential while Close-up Diamond Attraction Power White showed the lowest abrasive potential on eroded enamel in vitro. CLINICAL SIGNIFICANCE: This study showed that some commercial whitening toothpastes, especially those containing pyrophosphate associated with hydrated silica, enhanced enamel erosive wear. PMID- 29178760 TI - Clinical evaluation of a toothpaste containing lysozyme for removal of extrinsic stains on the tooth surface: An 8-week, double-blind, randomized study. AB - PURPOSE: To assess the efficacy and safety of application of a toothpaste containing lysozyme to remove extrinsic stains on the tooth surface in an 8-week trial. METHODS: 70 adult participants with extrinsic staining of the tooth surface were recruited to this randomized, parallel-controlled, double-blind clinical trial. Participants were allocated randomly to the test group or the control group and the study procedure and correct usage of the toothpaste were explained to them. Staining, measured by the Lobene stain index, and any side effects, were recorded over the course of the 8 weeks. All data were analyzed using SAS software version 8.0. RESULTS: 69 participants completed the study. The value of the Lobene stain index was significantly reduced (P< 0.05) in the treatment group compared with the control group after both 4 and 8 weeks. No obvious side effects were observed. CLINICAL SIGNIFICANCE: The results of this clinical study showed that the toothpaste containing lysozyme was effective in removing extrinsic staining on the tooth surface. PMID- 29178761 TI - Long-term outcomes of pulpotomy in permanent teeth with irreversible pulpitis: A multi-center randomized controlled trial. AB - PURPOSE: To compare success rates of full pulpotomy (FP) with two endodontic biomaterials on symptomatic vital teeth with closed apices in the presence of apical periodontitis. METHODS: In this multicenter controlled clinical trial, 412 volunteers met the inclusion criteria; they were all randomly allocated to either FP/ProRoot mineral trioxide aggregate (MTA) or FP/calcium enriched mixture (CEM) group. The subjects were followed up for 2 and 5 years to evaluate and compare the treatment outcomes. Data were analyzed using Chi square test and the multiple binary logistic regression model. RESULTS: Data for a total number of 344 and 304 subjects were available for 2- and 5-year follow-ups. In terms of clinical outcomes, 2- and 5-year success rates of both groups were >= 98%, without significant differences. In terms of radiographic outcomes, the 2-year result of FP/MTA was significantly superior to FP/CEM (P= 0.005); however, the 5-year success rates were similar (P= 0.413). Age and preoperative periapical status did not affect the treatment outcomes. CLINICAL SIGNIFICANCE: Both MTA and CEM biomaterials were found to be equally effective pulpotomy agents for mature permanent molars with irreversible pulpitis and associated apical periodontitis in different age groups. The performance of this novel minimally invasive biotechnology may support a paradigm shift towards more biologic/conservative treatments in dentistry worldwide. PMID- 29178762 TI - Adverse effects of salivary contamination for adhesives in restorative dentistry. A literature review. AB - PURPOSE: To review and critically analyze the literature concerning the influence of salivary contamination on the bond quality of adhesives used in restorative materials by comparing and contrasting the different adhesive materials. METHODS: A detailed search on PUBMED, Cochrane Library, Google Scholar and Web of Science was carried out to identify publications on salivary contamination and dental adhesive materials, from 1990-2017 (March) which resulted in a total of 6,202 web identified publications. After screening titles/abstracts and de-duplicating, 54 publications were selected that matched the requirements for this review. The condition for selection was English literature concerning the effect of salivary contamination on the adhesives used in restorative dentistry. The obtained articles were systematically evaluated. RESULTS: Salivary contamination of adhesives during restorative procedures statistically (64.6%) showed an adverse effect on adhesives, occurring either at one or many stages of restoration. Methodological dissimilarities impeded the direct comparison of the selected studies. Nevertheless, the 2-step etch and rinse adhesives were relatively less vulnerable to salivary contamination than the others. 65% of the evaluated studies for decontamination achieved improved bonding when the contaminated surface was subjected to some kind of decontamination procedure. However, the duration and other specificities were not standard in all the evaluations and need further research to assess the course of action. It is necessary to do long term studies to evaluate the effectiveness of contaminated adhesive over time. CLINICAL SIGNIFICANCE: Salivary contamination is a potential cause for poor bond quality of adhesive systems during restorative procedures and to provide a successful treatment, proper care must be taken to ensure the operating area is free from contamination. Understanding the properties of the materials and its constituents as well as considering measures to manage the potential vulnerabilities due to salivary contamination in the area of bonding might help a clinician to produce better results.

AB - PURPOSE: To evaluate fracture strength of different preparation designed onlay and overlay restorations produced by Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) and three different new ceramic-polymer blocks. METHODS: Ninety-one extracted human mandibular molars were used in this study. Preparations were made as (1) Only functional cusps reduction, (2) Only functional cusps reduction+rounded shoulder finish line, (3) All cusps reduction, or (4) All cusps reduction+rounded shoulder finish line. Then these four cavity types were restored with three different materials: VITA Enamic, GC Cerasmart, Lava Ultimate. Thirteen groups were created by added control group (n= 7). Adhesive cementation was achieved by using a dual cured composite resin adhesive cement RelyX Ultimate. All samples were subjected to thermocycling for 5,000 cycles in water baths between 50 degrees C and 55 degrees C. The fracture resistance of specimens was determined under compressive loads along the long axis of the restored teeth at 0.5 mm/minute crosshead speed until fracture with a universal test machine. Fracture types of restored groups were evaluated. For fracture resistance data, one-way ANOVA; for correlation between material type and preparation design, two-way ANOVA were used. Percentage table and Kruskal Wallis test were performed for analysis of fracture types. RESULTS: There was no significant difference between all the groups (one-way ANOVA, P> 0.05). Group 4 showed statistically higher fracture strength values than Group 1 and no significant difference was found among other preparation designs by two-way ANOVA that compared all types of preparation designs regardless of material difference (P< 0.05). CLINICAL SIGNIFICANCE: The results of the present study could help clinicians regarding which materials and type of preparations should be selected for onlay and overlay restorations produced with newly introduced ceramic-polymer CAD/CAM materials. PMID- 29178764 TI - Initial microbial colonization of enamel in children with different levels of caries activity: An in situ study. AB - PURPOSE: To investigate patterns of overnight in situ microbial colonization of enamel in children. METHODS: Overall, 29 children (aged 5-9 years) participated in the study. Nine were caries-free with no decayed, missing, or filled teeth (DMFT), 11 were caries-rehabilitated (DMFT >= 2, no active carious lesions), and nine were caries-active (DMFT >= 2, at least two carious lesions). Bovine enamel samples were fixed on individual upper jaw splints stored overnight in situ. 4',6 diamidino-2-phenylindole (DAPI) combined with Concanavalin A staining was applied for fluorescence microscopic visualization of total adherent bacteria and glucans. Fluorescence in situ hybridization (FISH) was used for distinction of eubacteria, streptococci, and Candida albicans. Salivary samples were investigated for Streptococcus mutans (S. mutans) by using CRT bacteria test and yeasts with Calcofluor white (CFW) staining. RESULTS: With all fluorescence methods, bacteria but not Candida albicans were detected on enamel samples. No statistically significant differences were observed in distribution patterns of the adherent bacteria between the groups. CFW staining indicated fungal structures in saliva samples of all participants. Based on CRT test results, the lowest amount of S. mutans were observed in caries-free children. Thus, initial microbial colonization patterns of enamel in children are not influenced by caries activity. CLINICAL SIGNIFICANCE: Caries activity in children may influence the process of initial bioadhesion and thus distribution patterns of bacterial attachment to the enamel surface. Investigation of in situ biofilm formation might provide valuable insights regarding the varying caries susceptibility in children. PMID- 29178765 TI - Ion release and in vitro enamel fluoride uptake associated with pit and fissure sealants containing microencapsulated remineralizing agents. AB - PURPOSE: To determine if pit-and-fissure sealants with microencapsulated remineralizing agents with sustained release of fluoride, calcium and phosphate ions could promote enamel fluoride uptake by demineralized tooth structure. METHODS: Sealants that contained 5 w/w% microcapsules with aqueous solutions of 5M Ca(NO3)2 or 0.8M NaF or 6.0M K2HPO4 or a mixture of all three were prepared. Ion release profiles were measured as a function of time. Enamel fluoride uptake by demineralized tooth structure was determined. RESULTS: Sustained release of fluoride, calcium and phosphate ions from a sealant was demonstrated. Fluoride uptake by demineralized enamel was significantly increased compared to a control sealant manufactured without microcapsules (P< 0.01). Bovine enamel that contained 2.2+/-2.1 ug F/g of enamel prior to exposure to a sealant without microcapsules had 2.3+/-0.5 after 90 days. Enamel exposed to sealant with 5w/% NaF microcapsules went from 3.5+/-3.5 ug F/g of enamel prior to exposure to 148+/ 76 after 90 days. Enamel exposed to sealant with 2 w/w% NaF, 2 w/w% Ca(NO3)2 and 1 w/w% K2HPO4 microcapsules went from 1.7+/-0.7 ug F/g of enamel prior to exposure to 190+/-137 after 90 days. CLINICAL SIGNIFICANCE: Sealants with encapsulated remineralizing agents were capable of releasing biologically available fluoride, calcium, and phosphate ions. Incorporation of these microcapsules in pit and fissure sealants is a promising method for remineralization determined by enamel fluoride uptake measurements. PMID- 29178766 TI - Light energy transmission and Vickers hardness ratio of bulk-fill resin based composites at different thicknesses cured by a dual-wave or a single-wave light curing unit. AB - PURPOSE: To quantify light energy transmission through two bulk-fill resin-based composites and to measure the top to bottom surface Vickers hardness ratio (VHratio) of samples of various incremental thicknesses, using either a single wave or dual-wave light curing unit (LCU). METHODS: Tetric EvoCeram Bulk Fill (TECBF) and SonicFill (SF) were studied. Using MARC-RC, the irradiance delivered to the top surface of the samples 2, 3, 4 and 5 mm thick (n= 5 for each thickness) was adjusted to 800 mW/cm2 for 20 seconds (16 J/cm2) using either a single-wave, Bluephase or a dual-wave, Bluephase G2 LCUs. Light energy transmission through to the bottom surface of the specimens was measured at real time using MARC-RC. The Vickers hardness (VH) was determined using Vickers micro hardness tester and the VHratio was calculated. Data were analyzed using a general linear model in Minitab 16; alpha= 0.05. RESULTS: TECBF was more translucent than SF (P< 0.05). The mean VHratio was higher than 80% in 2, 3 and 4 mm increment thickness for both materials (except for 4 mm TECBF when cured with the dual-wave Bluephase G2). SF showed significantly higher VH ratio than TECBF at all different thickness levels (P< 0.05), except at the 2 mm level (P> 0.05). TECBF showed significantly greater VH ratio when cured with the single-wave Bluephase than when using the dual-wave Bluephase G2 (P< 0.05). CLINICAL SIGNIFICANCE: The transmission of light energy through to the bottom surface and the VHratio are material dependent. Although TECBF is more translucent than SF, it showed lower VHratio compared to SF when cured with dual-wave Bluephase G2. PMID- 29178767 TI - Effect of oxygen inhibition in universal adhesives on dentin bond durability and interfacial characteristics. AB - PURPOSE: To evaluate the effects of oxygen inhibition of universal adhesive on dentin bond durability and interfacial characteristics. METHODS: The three universal adhesives used were Scotchbond Universal Adhesive, Prime & Bond Elect, and G-Premio Bond. Shear bond strength (SBS) and shear fatigue strength (SFS) of resin composite bonded to adhesive with and without an oxygen inhibited layer (OIL) on dentin using total-etch and self-etch modes were determined. Surface free energy (SFE) and SFE parameters of cured adhesive with and without an OIL on dentin using total-etch and self-etch modes were also measured by the sessile drop method. RESULTS: The presence of an OIL in universal adhesives promoted higher SBS and SFS regardless of etching mode. In addition, regardless of adhesive type and etching modes, the specimens with an OIL showed a higher ratio of SFS/SBS than those without an OIL. Further, the SFEs, especially total SFE, polarity force and hydrogen bonding force, of cured adhesives with an OIL were significantly higher than those without an OIL. CLINICAL SIGNIFICANCE: The present findings indicated that the oxygen inhibition of universal adhesive did not impair the dentin bond durability and interfacial characteristics of the adhesive. PMID- 29178768 TI - A global approach to assess the economic benefits of increased consumption of sugar-free chewing gum. AB - PURPOSE: To analyze the influence of increasing the average consumption of sugar free gum (SFG) in 25 industrialized countries on dental expenditures due to caries by the national health care systems. It was assumed that large cost savings were possible, because the regular consumption of SFG significantly reduces the relative risk of caries and therefore, improves dental health, which reduces expenditures on dental treatments. METHODS: A budget impact analysis (BIA) was performed to model the decrease in the relative risk of caries and the subsequent cost savings for dental care. Annual consumption of SFG, dental expenditures due to caries, chewing frequencies by age groups and the relative risk reduction for caries due to the consumption of SFG were identified and used as model parameters. Three different scenarios for the increase in the number of SFG were calculated. Besides overall results for all countries together, analyses were conducted for countries grouped by regions and the Human Development Index (HDI). RESULTS: For the entity of all 25 analyzed countries together, possible annual cost savings range from US$805.77 M in the scenario with the lowest increase of SFG consumption up to US$18,248 billion in the scenario with the biggest increase of SFG consumption. Europe and the USA show potential cost savings of US$1,061 billion and US$2,071 billion per year, respectively, if all chewers increase their consumption of SFG by 1 piece per day. The analysis showed the potential cost savings in dental expenditures due to caries that can be achieved by only slightly increasing the consumption of SFG. The regular consumption of SFG cannot replace good dental hygiene like tooth brushing, but can have a significant impact on dental health, which can lead to increased cost savings for health care systems worldwide. CLINICAL SIGNIFICANCE: Based on the fact that a regular consumption of sugar-free chewing gum has the beneficial effect of reducing caries prevalence, an increased consumption may not only lead to improved dental health but significant cost savings in expenditures for dental treatment worldwide. PMID- 29178769 TI - Effects of desensitizing agents for cervical dentin hypersensitivity: A randomized clinical trial. AB - PURPOSE: To evaluate the clinical efficacy of five commercially available desensitizing agents with different mechanisms applied to hypersensitive teeth. METHODS: A randomized clinical trial was conducted on subjects suffering dentin hypersensitivity in Korea University Guro Hospital from October 2013 to April 2015. A total of 64 subjects met the selection criteria and were randomly assigned to five commercially available desensitizing agents, and applied according to the manufacturers' instructions. Before and after application of desensitizing agents, subjects were evaluated with the Visual Analogue Scale (VAS) at baseline, 1 week, 1 month and 3 months. The difference between the degree of reduction of hypersensitivity in relation to time were evaluated with the repeated-measures ANOVA (P<0.05). RESULTS: Practitioner and subject-measured VAS values at 1 week, 1 month and 3 months showed a significant difference in all products compared with the first visit. On the other hand, no statistically significant differences between the products was shown. Desensitizing agents used in this clinical trial relieved dentin hypersensitivity up to 3 months. CLINICAL SIGNIFICANCE: The five tested desensitizing agents with different mechanisms were clinically effective in relieving dentin hypersensitivity up to 3 months and showed statistically significant pain reduction when compared to baseline scores. PMID- 29178770 TI - Antibiotic prophylaxis for preventing dental implant failure and postoperative infection: A systematic review of randomized controlled trials. AB - PURPOSE: To investigate whether prophylactic antibiotics are beneficial on patients undergoing routine dental implant placement procedures and to investigate which administration regimen is the most effective. METHODS: The primary outcome was implant failure; the secondary outcome was postoperative infection. In the fixed-effects model, the Mantel-Haenszel method was used to calculate pooled relative risks (RRs) at 95% confidence intervals (CIs). To determine the outcomes, the quality of available evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). RESULTS: Prophylactic antibiotics significantly decreased the incidence of implant failure (RR, 0.29; 95% CI, 0.15-0.55; P= 0.0002; I2= 0%) but did not decrease infection. There was no statistically significant difference between single preoperative antibiotics (SPA) and preoperative and postoperative antibiotics (PPA) while treating patients with dental implant failure (RR, 1.07; 95% CI, 0.31-3.62; P= 0.92). No statistically significant difference was observed between SPA and PPA when prescribed to treat infection postoperatively (RR, 1.05; 95% CI, 0.29-3.85; P= 0.94; I2= 0%). CLINICAL SIGNIFICANCE: The administration of prophylactic antibiotics significantly reduced the failure of dental implants under ordinary conditions. Furthermore, single preoperative antibiotics and preoperative and postoperative antibiotics had similar effects on dental implant failures and infections. PMID- 29178771 TI - Effect of different concentrations and application times of proanthocyanidin gels on dentin erosion. AB - PURPOSE: To analyze the effect of different concentrations and application times of proanthocyanidin gels on dentin before an erosive challenge in order to evaluate if there is a dose-response or application time-response relationship in the use of these gels for erosion prevention. METHODS: 80 bovine root dentin blocks were randomly and equally divided into 10 groups and treated according to the two factors under study (purified grape seed proanthocyanidin gel concentration and time of application): 0.05P1: 0.05% proanthocyanidin gel during 1 minute; 0.05P5: 0.05% proanthocyanidin gel during 5 minutes; 1P1: 1% proanthocyanidin gel during 1 minute; 1P5: 1% proanthocyanidin gel during 5 minutes; 5P1: 5% proanthocyanidin gel during 1 minute; 5P5: 5% proantho-cyanidin gel during 5 minutes; 10P1: 10% proanthocyanidin gel during 1 minute; 10P5: 10% proanthocyanidin gel during 5 minutes; Control 1: placebo gel during 1 minute; and Control 5: placebo gel during 5 minutes. The gels were applied over dentin blocks once before the first erosive challenge. After that, the blocks were subjected to three erosive cycles per day, during 5 days. Profilometry was used to quantify the dentin loss (um). Data were analyzed by two-way ANOVA and Fisher's test (P< 0.05). RESULTS: Statistical analysis showed that there was no significant difference between the application times. The different concentrations of proanthocianidin gels presented similar results (P> 0.05). All tested gels resulted in significantly less wear when compared to the placebo gel. CLINICAL SIGNIFICANCE: Grape seed proanthocyanidin gels could be considered as a promising therapy to diminish erosive dentin wear because it may interact with the exposed collagen, enhancing the demineralized organic matrix stabilization, which acts as a barrier against the diffusion of the acids from erosion. PMID- 29178772 TI - Antimicrobial action and long-term effect of overnight denture cleansers. AB - PURPOSE: To evaluate two denture cleansers for overnight soaking (0.5% sodium hypochlorite and peroxide alkaline) regarding efficacy against Candida spp. biofilms (randomized clinical trial) and their effects on the physical properties of a denture base acrylic resin simulating a period of 5 years of use (laboratory study). The Candida spp. were identified and their resistance to main antifungal agents was evaluated. METHODS: 32 complete denture wearers were instructed to brush their dentures three times a day and to soak them (>=8 hours) in: control - water (C); alkaline peroxide (AP); or 0.5% sodium hypochlorite (SH). According to a randomized sequence, each solution was used for three alternate periods of 7 days. The antimicrobial action was performed by counting the colony forming units (CFU) of Candida spp. For collection of the biofilm, each upper complete denture was placed in a Petri dish, the internal surface was brushed (Tek brush) with saline solution for 2 minutes and the suspension was transferred to a test tube. After dilutions (10 0 to 10-3), aliquots of 50 uL were seeded inside Petri dishes containing Candida Chromagar. After incubation, the colonies were counted and the values of CFU/mL calculated. Data were transformed in log10 (CFU +1) and analyzed by the Friedman test (alpha= 0.05) followed by Wilcoxon and Bonferroni tests (alpha= 0.05). Each of the different species identified perfunctorily has been confirmed through the identification of yeasts kit. The resistance to antifungal agents (amphotericin B, nystatin, flucytosine, econazole, ketoconazole, miconazole and fluconazole) was also evaluated. Adverse effects were estimated on heat-polymerized resin specimens, simulating a 5-year period of overnight use. Acrylic resin specimens were randomly distributed into three groups: C: Control (distilled water); AP: alkaline peroxide; and SH: 0.5% sodium hypochlorite. Color change, surface roughness and flexural strength were evaluated at baseline and after immersion procedures. Data were compared by Kruskall-Wallis followed by Dunn's test (color change and surface roughness) and one-way ANOVA (flexural strength) (alpha= 0.05). RESULTS: There was a reduction of Candida spp. counts after using both solutions (AP and SH). The Candida spp. most often isolated was C. albicans, followed by the C. glabrata. Only 24.7% of isolate strains were resistant to at least one of the tested antifungals, highlighting azole compounds. Immersion in AP [ 5.73 (5.45-5.91)] caused significantly higher color change, with lower DeltaE values for C [1.12 (1.15-1.37) ] followed by SH [3.70 (3.51-3.98) ]. The NBS values were classified as "slight" for C (1.12) group and " considerable" for AP (5.27) and SH (3.40). No solution altered surface roughness significantly. Flexural strength (in MPa) was significantly lower for C (64.59), AP (63.96 +/- 12.98) and SH (62.84 +/- 8.62) when compared to a group without any immersion (109.12 +/- 8.37). CLINICAL SIGNIFICANCE: Both solutions tested presented antimicrobial action against Candida spp. and may be useful for denture biofilm control, but should be used with caution as an overnight immersion solution since they may damage denture bases in the long-term. Candida was most frequently isolated at baseline and after using the products. Only 24.7% of isolate strains were resistant to at least one of the tested antifungals, especially with azole compounds. PMID- 29178773 TI - Comparison of nanofluoridated hydroxyapatite of varying fluoride content for dentin tubule occlusion. AB - PURPOSE: To evaluate the viability of a series of nano-fluoridated hydroxyapatite (nano-FHA) formulations of varying fluoride content for the occlusion of exposed dentin tubules, in comparison to nano-hydroxyapatite (nano-HA). METHODS: Nano-FHA powders with varying levels of fluoride ion were synthesized to substitute hydroxyl ions (-OH) present in hydroxyapatite (HA). Nano-FHA were defined as 2nFHA,4nFHA,6nFHA, 8nFHA and 10nFHA, with the molar ratio of F(- to Ca243; of 0.002,0.004,0.006,0.008 and 0.01, respectively. The powders were synthesized using a wet chemistry route, and characterized by transmission electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy. The methylthiazol tetrazolium (MTT) assay was used to assess cell viability toward nano-FHA. According to the content of F-, the nano-nFHA and nano-HA powders were divided into six groups, with the artificial saliva as control. They were spread over the dentin surface for 1 minute and repeated three times per day for 7 consecutive days. After washing and brushing with distilled water for an additional 7 days, scanning electron microscopy was used to evaluate the in vitro plugging rate of the tubules and penetrating depth. RESULTS: The 2nFHA, 4nFHA, 6nFHA, 8nFHA and 10nFHA powders were prepared and characterized. The 8nFHA had less crystallinity compared to 2nFHA,4nFHA, and 6nFHA.The MTT assay (from 12 to 120 hours) showed that the cell viability of the L-929 fibroblasts in the 2nFHA, 4nFHA, 6nFHA, 8nFHA, 10nFHA, and nano-HA groups ranged from 80.54+/- 3.35% to 112.9+/- 4.8%. Most of the nano-FHA powders successfully occluded dentin tubules. The plugging rate of 8nFHA was significantly higher than that of the 2nFHA, 4nFHA, 6nFHA and nano-HA groups. The penetrating depth of the 8nFHA group into the tubules was also significantly higher than that of the other nano-FHA and nano-HA group. CLINICAL SIGNIFICANCE: The nano-FHA formulation 8nFHA showed higher plugging rate and penetrating depth into the tubules. It has the potential to be used as a desensitizing agent in treating dentin hypersensitivity with better long-term durability and efficacy of dentin tubule occlusion. PMID- 29178774 TI - Binding of Polythiophenes to Amyloids: Structural Mapping of the Pharmacophore. AB - Luminescent conjugated polythiophenes bind to amyloid proteins with high affinity. Their fluorescence properties, which are modulated by the detailed conformation in the bound state, are highly sensitive to structural features of the amyloid. Polythiophenes therefore represent diagnostic markers for the detection and differentiation of pathological amyloid aggregates. We clarify the binding site and mode of two different polythiophenes to fibrils of the prion domain of the HET-s protein by solid-state NMR and correlate these findings with their fluorescence properties. We demonstrate how amyloid dyes recognize distinct binding sites with specific topological features. Regularly spaced surface charge patterns and well-accessible grooves on the fibril surface define the pharmacophore of the amyloid, which in turn determines the binding mode and fluorescence wavelength of the polythiophene. PMID- 29178775 TI - Brush-Like Cobalt Nitride Anchored Carbon Nanofiber Membrane: Current Collector Catalyst Integrated Cathode for Long Cycle Li-O2 Batteries. AB - To achieve a high reversibility and long cycle life for lithium-oxygen (Li-O2) batteries, the irreversible formation of Li2O2, inevitable side reactions, and poor charge transport at the cathode interfaces should be overcome. Here, we report a rational design of air cathode using a cobalt nitride (Co4N) functionalized carbon nanofiber (CNF) membrane as current collector-catalyst integrated air cathode. Brush-like Co4N nanorods are uniformly anchored on conductive electrospun CNF papers via hydrothermal growth of Co(OH)F nanorods followed by nitridation step. Co4N-decorated CNF (Co4N/CNF) cathode exhibited excellent electrochemical performance with outstanding stability for over 177 cycles in Li-O2 cells. During cycling, metallic Co4N nanorods provide sufficient accessible reaction sites as well as facile electron transport pathway throughout the continuously networked CNF. Furthermore, thin oxide layer (<10 nm) formed on the surface of Co4N nanorods promote reversible formation/decomposition of film type Li2O2, leading to significant reduction in overpotential gap (~1.23 V at 700 mAh g-1). Moreover, pouch-type Li-air cells using Co4N/CNF cathode stably operated in real air atmosphere even under 180 degrees bending. The results demonstrate that the favorable formation/decomposition of reaction products and mediation of side reactions are hugely governed by the suitable surface chemistry and tailored structure of cathode materials, which are essential for real Li-air battery applications. PMID- 29178776 TI - Evidence for Chemical and Electronic Nonuniformities in the Formation of the Interface of RbF-Treated Cu(In,Ga)Se2 with CdS. AB - We report on the initial stages of CdS buffer layer formation on Cu(In,Ga)Se2 (CIGSe) thin-film solar cell absorbers subjected to rubidium fluoride (RbF) postdeposition treatment (PDT). A detailed characterization of the CIGSe/CdS interface for different chemical bath deposition (CBD) times of the CdS layer is obtained from spatially resolved atomic and Kelvin probe force microscopy and laterally integrating X-ray spectroscopies. The observed spatial inhomogeneity in the interface's structural, chemical, and electronic properties of samples undergoing up to 3 min of CBD treatments is indicative of a complex interface formation including an incomplete coverage and/or nonuniform composition of the buffer layer. It is expected that this result impacts solar cell performance, in particular when reducing the CdS layer thickness (e.g., in an attempt to increase the collection in the ultraviolet wavelength region). Our work provides important findings on the absorber/buffer interface formation and reveals the underlying mechanism for limitations in the reduction of the CdS thickness, even when an alkali PDT is applied to the CIGSe absorber. PMID- 29178777 TI - Electronic Modulation of Electrocatalytically Active Center of Cu7S4 Nanodisks by Cobalt-Doping for Highly Efficient Oxygen Evolution Reaction. AB - Cu-based electrocatalysts have seldom been studied for water oxidation because of their inferior activity and poor stability regardless of their low cost and environmentally benign nature. Therefore, exploring an efficient way to improve the activity of Cu-based electrocatalysts is very important for their practical application. Modifying electronic structure of the electrocatalytically active center of electrocatalysts by metal doping to favor the electron transfer between catalyst active sites and electrode is an important approach to optimize hydrogen and oxygen species adsorption energy, thus leading to the enhanced intrinsic electrocatalytic activity. Herein, Co-doped Cu7S4 nanodisks were synthesized and investigated as highly efficient electrocatalyst for oxygen evolution reaction (OER) due to the optimized electronic structure of the active center. Density functional theory (DFT) calculations reveal that Co-engineered Cu7S4 could accelerate electron transfer between Co and Cu sites, thus decrease the energy barriers of intermediates and products during OER, which are crucial for enhanced catalytic properties. As expected, Co-engineered Cu7S4 nanodisks exhibit a low overpotential of 270 mV to achieve current density of 10 mA cm-2 as well as decreased Tafel slope and enhanced turnover frequencies as compared to bare Cu7S4. This discovery not only provides low-cost and efficient Cu-based electrocatalyst by Co doping, but also exhibits an in-depth insight into the mechanism of the enhanced OER properties. PMID- 29178778 TI - Combinatorial Discovery of Lanthanum-Tantalum Oxynitride Solar Light Absorbers with Dilute Nitrogen for Solar Fuel Applications. AB - Oxynitrides with the photoelectrochemical stability of oxides and desirable band energetics of nitrides comprise a promising class of materials for solar photochemistry. Challenges in synthesizing a wide variety of oxynitride materials has limited exploration of this class of functional materials, which we address using a reactive cosputtering combined with rapid thermal processing method to synthesize multi-cation-multi-anion libraries. We demonstrate the synthesis of a LaxTa1-xOyNz thin film composition spread library and its characterization by both traditional thin film materials characterization and custom combinatorial optical spectroscopy and X-ray absorption near edge spectroscopy (XANES) techniques, ultimately establishing structure-chemistry-property relationships. We observe that over a substantial La-Ta composition range the thin films crystallize in the same perovskite LaTaON2 structure with significant variation of anion chemistry. The relative invariance in optical band gap demonstrates a remarkable decoupling of composition and band energetics so that the composition can be optimized while retaining the desirable 2 eV band gap energy. We also demonstrate the intercalation of diatomic nitrogen into the La3TaO7 structure, which gives rise to a direct-allowed optical transition at 2.2 eV, less than half the value of the oxide's band gap. These findings motivate further exploration of the visible light response of this material that is predicted to be stable over a wide range of electrochemical potential. PMID- 29178779 TI - Synthesis of bis-Phosphate Iminoaltritol Enantiomers and Structural Characterization with Adenine Phosphoribosyltransferase. AB - Phosphoribosyl transferases (PRTs) are essential in nucleotide synthesis and salvage, amino acid, and vitamin synthesis. Transition state analysis of several PRTs has demonstrated ribocation-like transition states with a partial positive charge residing on the pentose ring. Core chemistry for synthesis of transition state analogues related to the 5-phospho-alpha-d-ribosyl 1-pyrophosphate (PRPP) reactant of these enzymes could be developed by stereospecific placement of bis phosphate groups on an iminoaltritol ring. Cationic character is provided by the imino group and the bis-phosphates anchor both the 1- and 5-phosphate binding sites. We provide a facile synthetic path to these molecules. Cyclic-nitrone redox methodology was applied to the stereocontrolled synthesis of three stereoisomers of a selectively monoprotected diol relevant to the synthesis of transition-state analogue inhibitors. These polyhydroxylated pyrrolidine natural product analogues were bis-phosphorylated to generate analogues of the ribocationic form of 5-phosphoribosyl 1-phosphate. A safe, high yielding synthesis of the key intermediate represents a new route to these transition state mimics. An enantiomeric pair of iminoaltritol bis-phosphates (L-DIAB and D DIAB) was prepared and shown to display inhibition of Plasmodium falciparum orotate phosphoribosyltransferase and Saccharomyces cerevisiae adenine phosphoribosyltransferase (ScAPRT). Crystallographic inhibitor binding analysis of L- and D-DIAB bound to the catalytic sites of ScAPRT demonstrates accommodation of both enantiomers by altered ring geometry and bis-phosphate catalytic site contacts. PMID- 29178780 TI - Extraordinary Effects in Quasi-Periodic Gold Nanocavities: Enhanced Transmission and Polarization Control of Cavity Modes. AB - Plasmonic quasi-periodic structures are well-known to exhibit several surprising phenomena with respect to their periodic counterparts, due to their long-range order and higher rotational symmetry. Thanks to their specific geometrical arrangement, plasmonic quasi-crystals offer unique possibilities in tailoring the coupling and propagation of surface plasmons through their lattice, a scenario in which a plethora of fascinating phenomena can take place. In this paper we investigate the extraordinary transmission phenomenon occurring in specifically patterned Thue-Morse nanocavities, demonstrating noticeable enhanced transmission, directly revealed by near-field optical experiments, performed by means of a scanning near-field optical microscope (SNOM). SNOM further provides an intuitive picture of confined plasmon modes inside the nanocavities and confirms that localization of plasmon modes is based on size and depth of nanocavities, while cross talk between close cavities via propagating plasmons holds the polarization response of patterned quasi-crystals. Our performed numerical simulations are in good agreement with the experimental results. Thus, the control on cavity size and incident polarization can be used to alter the intensity and spatial properties of confined cavity modes in such structures, which can be exploited in order to design a plasmonic device with customized optical properties and desired functionalities, to be used for several applications in quantum plasmonics. PMID- 29178781 TI - Kinetics and Chemistry of Hydrolysis of Ultrathin, Thermally Grown Layers of Silicon Oxide as Biofluid Barriers in Flexible Electronic Systems. AB - Flexible electronic systems for bioimplants that offer long-term (multidecade) stability and safety in operation require thin, biocompatible layers that can prevent biofluid penetration. Recent work shows that ultrathin films of silicon dioxide thermally grown (TG-SiO2) on device-grade silicon wafers and then released as transferrable barriers offer a remarkable set of attributes in this context. This paper examines the chemical stability of these materials in aqueous solutions with different combinations of chemistries that are present in biofluids. Systematic measurements reveal the dependence of the dissolution rate of TG-SiO2 on concentrations of cations (Na+, K+, Mg2+, Ca2+) and anions (Cl-, HPO42-) at near-neutral pH. Certain results are consistent with previous studies on bulk samples of quartz and nanoparticles of amorphous silica; others reveal significant catalyzing effects associated with divalent cations at high pH and with specific anions at high ionic strength. In particular, Ca2+ and HPO42- greatly enhance and silicic acid greatly reduces the rates. These findings establish foundational data of relevance to predicting lifetimes of implantable devices that use TG-SiO2 as biofluid barriers, and of other classes of systems, such as environmental monitors, where encapsulation against water penetration is important.

AB - Aggregation-induced optical responses are ubiquitous among a wide range of organic and inorganic compounds. Here, we demonstrate an unprecedented effect of aggregation on the photoluminescence (PL) profiles of [core + exo]-type [Au8]4+ clusters, which displayed a change in the dominant PL emission mode from fluorescence to phosphorescence-type upon aggregation. In solvents in which cluster molecules are highly soluble and exist as monomers, they displayed single PL bands at ~600 nm at ambient temperatures. However, in solvents in which cluster molecules are less soluble and cluster aggregation is induced, a new PL band at ~700 nm also emerged. Lifetime measurements revealed that the PL emissions at ~600 and ~700 nm had fluorescence and phosphorescence characters, respectively. Studies of the excitation spectra suggested that organized cluster assemblies were responsible for the lower-energy emission at ~700 nm and had exceptionally high emission activity. Accordingly, intense phosphorescence-type emissions were observed in the solid state in which the quantum efficiencies were higher by two orders of magnitude than those of the corresponding monomeric forms in solution. This work provides an example of the critical effects of cluster aggregation events on their optical properties and shows the potential of such effects in the design of cluster-based materials with unique functions and properties.

AB - A metal surface passivated with a tightly packed self-assembled monolayer (SAM) can be made catalytically active upon the metal's mechanical deformation. This deformation renders the SAM sparser and exposes additional catalytic sites on the metal's surface. If the deformation is elastic, return of the metal to the original shape "heals" the SAM and nearly extinguishes the catalytic activity. Kelvin probe force microscopy and theoretical considerations both indicate that the catalytic domains "opening up" in the deformed SAM are of nanoscopic dimensions. PMID- 29178784 TI - Differential Compound Prioritization via Bidirectional Selectivity Push with Power. AB - Effective in silico compound prioritization is a critical step to identify promising drug candidates in the early stages of drug discovery. Current computational methods for compound prioritization usually focus on ranking the compounds based on one property, typically activity, with respect to a single target. However, compound selectivity is also a key property which should be deliberated simultaneously so as to minimize the likelihood of undesired side effects of future drugs. In this paper, we present a novel machine-learning based differential compound prioritization method dCPPP. This dCPPP method learns compound prioritization models that rank active compounds well, and meanwhile, preferably rank selective compounds higher via a bidirectional selectivity push strategy. The bidirectional push is enhanced by push powers that are determined by ranking difference of selective compounds over multiple bioassays. Our experiments demonstrate that the new method dCPPP achieves significant improvement on prioritizing selective compounds over baseline models.

AB - The alpha4beta2 nAChR is the most predominant subtype in the brain and is a well known culprit for nicotine addiction. Previously we presented a series of alpha4beta2 nAChR selective compounds that were discovered from a mixture-based positional-scanning combinatorial library. Here we report further optimization identified highly potent and selective alpha4beta2 nAChR antagonists 5 (AP-202) and 13 (AP-211). Both compounds are devoid of in vitro agonist activity and are potent inhibitors of epibatidine-induced changes in membrane potential in cells containing alpha4beta2 nAChR, with IC50 values of approximately 10 nM, but are weak agonists in cells containing alpha3beta4 nAChR. In vivo studies show that 5 can significantly reduce operant nicotine self-administration and nicotine relapse-like behavior in rats at doses of 0.3 and 1 mg/kg. The pharmacokinetic data also indicate that 5, via sc administration, is rapidly absorbed into the blood, reaching maximal concentration within 10 min with a half-life of less than 1 h.

AB - The first example of the SN2' reaction type of the detrifluoroacetylatively in situ generated tertiary fluoro-enolates in the uncatalyzed reactions with Morita Baylis-Hillman derivatives has been described. The SN2' substitution takes place in a highly chemoselective manner as no corresponding SN2 products were observed in the reaction mixtures. Due to the excellent stereochemical outcome, the reactions seem to have an apparent synthetic value for the preparation of structurally new fluorinated oxindoles. PMID- 29178787 TI - Inter-Enzyme Allosteric Regulation of Chorismate Mutase in Corynebacterium glutamicum: Structural Basis of Feedback Activation by Trp. AB - Corynebacterium glutamicum is widely used for the industrial production of amino acids, nucleotides, and vitamins. The shikimate pathway enzymes DAHP synthase (CgDS, Cg2391) and chorismate mutase (CgCM, Cgl0853) play a key role in the biosynthesis of aromatic compounds. Here we show that CgCM requires the formation of a complex with CgDS to achieve full activity, and that both CgCM and CgDS are feedback regulated by aromatic amino acids binding to CgDS. Kinetic analysis showed that Phe and Tyr inhibit CgCM activity by inter-enzyme allostery, whereas binding of Trp to CgDS strongly activates CgCM. Mechanistic insights were gained from crystal structures of the CgCM homodimer, tetrameric CgDS, and the heterooctameric CgCM-CgDS complex, refined to 1.1, 2.5, and 2.2 A resolution, respectively. Structural details from the allosteric binding sites reveal that DAHP synthase is recruited as the dominant regulatory platform to control the shikimate pathway, similar to the corresponding enzyme complex from Mycobacterium tuberculosis.

AB - A cross-coupling of acyl chlorides with gem-difluorinated organozinc reagents affording difluorinated ketones is described.

PMID- 29178789 TI - Chelator-Free Labeling of Metal Oxide Nanostructures with Zirconium-89 for Positron Emission Tomography Imaging. AB - Radiolabeling of molecules or nanoparticles to form imaging probes is critical for positron emission tomography (PET) imaging, which, with high sensitivity and the ability for quantitative imaging, has been widely used in the clinic. While conventional radiolabeling often employs chelator molecules, a general method for chelator-free radiolabeling of a wide range of materials remains to be developed. Herein, we determined that 10 different types of metal oxide (MxOy, M = Gd, Ti, Te, Eu, Ta, Er, Y, Yb, Ce, or Mo, x = 1-2, y = 2-5) nanomaterials with polyethylene glycol (PEG) modification could be labeled with 89Zr, a PET tracer, via a simple yet general chelator-free radiolabeling method upon simple mixing. High-labeling yields and good serum stabilities are achieved with this method, owing to the strong bonding between oxyphilic 89Zr4+ with oxygen atoms on the MxOy surface. Selecting 89Zr-Gd2O3-PEG as a multimodal imaging probe, we have successfully demonstrated in vivo PET imaging of draining lymph nodes, which are also visualized under magnetic resonance imaging, showing advantages over free 89Zr in the mapping of draining lymph node networks. Our work describes a general and simple method for chelator-free radiolabeling of metal oxide nanostructures, which is promising for the development of multifunctional nanoprobes in biomedical imaging.

AB - The unique structural and electronic characteristics of graphene make it an attractive contact for fundamental single-molecule electrical studies. With this in mind, we have probed here the electrical conductance of a molecular junction based on alpha,omega-diaminoalkane chains sandwiched between a gold and a graphene electrode. Using an STM based I(s) method combined with density functional theory-based transport calculations, we demonstrate that the resulting attenuation factor turns out to be much lower when compared to the standard molecular junction between two gold electrodes. This effect is attributed to asymmetric coupling of the molecule through strong chemisorption at the gold electrode and weaker van der Waals contact at graphene. Moreover, this asymmetric coupling induces higher conductance than that in the same hybrid metal-graphene molecular junction using standard thiol anchoring groups. PMID- 29178794 TI - Polarizable Density Embedding: A Solution to the Electron Spill-Out Problem in Multiscale Modeling. AB - We analyze the performance of the polarizable density embedding (PDE) model-a new multiscale computational approach designed for prediction and rationalization of general molecular properties of large and complex systems. We showcase how the PDE model very effectively handles the use of large and diffuse basis sets that are otherwise questionable-due to electron spill-out effects-in standard embedding models. Based on our analysis, we find the PDE model to be robust and much more systematic than less sophisticated focused embedding models, and thus outline the PDE model as a very efficient and accurate approach to describe the electronic structure of ground and excited states as well as molecular properties of complex, heterogeneous systems. PMID- 29178795 TI - Accelerating Turnover Frequency in Nucleic Acid Templated Reactions. AB - Nucleic acid templated reactions have attracted attention as an important technology to sense oligonucleotides and to translate nucleic acid-based instructions into diverse outputs. Great progress has been made in accelerating the reaction in order to improve signal amplification, reaching rates where substrate turnover rather than chemical reaction is rate limiting. Herein we explore the utility of architectures inspired by three-way junction that yield a cleavage of a strand thus accelerating substrate turnover. We demonstrate that such design can overcome product inhibition in templated reactions and operate close to the rate of hybridization. PMID- 29178796 TI - Protein Nanopore-Based Discrimination between Selected Neutral Amino Acids from Polypeptides. AB - Nanopore probing of biological polymers has the potential to achieve single molecule sequencing at low cost, high throughput, portability, and minimal sample preparation and apparatus. In this article, we explore the possibility of discrimination between neutral amino acid residues from the primary structure of 30 amino acids long, engineered peptides, through the analysis of single-molecule ionic current fluctuations accompanying their slowed-down translocation across the wild type alpha-hemolysin (alpha-HL) nanopore, and molecular dynamics simulations. We found that the transient presence inside the alpha-HL of alanine or tryptophan residues from the primary sequence of engineered peptides results in distinct features of the ionic current fluctuation pattern associated with the peptide reversibly blocking the nanopore. We propose that alpha-HL sensitivity to the molecular exclusion at the most constricted region mediates ionic current blockade events correlated with the volumes that are occluded by at least three alanine or tryptophan residues, and provides the specificity needed to discriminate between groups of neutral amino acids. Further, we find that the pattern of current fluctuations depends on the orientation of the threaded amino acid residues, suggestive of a conformational anisotropy of the ensemble of conformations of the peptide on the restricted nanopore region, related to its relative axial orientation inside the nanopore.

AB - Indazoles represent a privileged scaffold in medicinal chemistry. In the presence of strong base, however, N-protected indazoles are prone to an undesirable ring opening reaction to liberate o-aminobenzonitriles. By employing unprotected indazoles with a free N-H bond, isomerization is averted because the heterocycle is deprotonated in situ. We herein report functional group-tolerant and robust C S couplings of bromoindazoles with thiols of varying electronic nature in the presence of lithium bis(trimethylsilyl)amide at elevated temperatures. PMID- 29178799 TI - Cryptophanes for Methane and Xenon Encapsulation: A Comparative Density Functional Theory Study of Binding Properties and NMR Chemical Shifts. AB - The host-guest chemistry of cryptophanes is an active research area because of its applications in sensor design, targeting small molecules and atoms in environmental and medical sciences. As such, the computational prediction of binding energies and nuclear magnetic resonance (NMR) properties of different cryptophane complexes are of interest to both theoreticians and experimentalists working in host-guest based sensor development. Herein we present a study of 10 known and some newly proposed cryptophanes using density functional theory (DFT) calculations. We benchmark the description of nonbonding interactions by different DFT functionals against spin-component-scaled, second-order Moller Plesset theory (SCS-MP2) and predict novel host molecules with enhanced affinity toward methane and Xenon, two representative systems of high interest. We demonstrate the power and limitations of the different computational methods in describing the binding and NMR properties of these established and novel host systems. The results show the importance of including dispersion corrections in the DFT functionals. The overall analysis of the dispersion corrections indicated that results obtained from pure DFT functionals should be used cautiously when conclusions are drawn for molecular systems with considerable weak interactions. Proposed analogues of cryptophane-A, where the alkoxy bridges are replaced by alkyl chains, are predicted to display enhanced affinity toward both methane and Xenon. PMID- 29178798 TI - Dissolution of Monocrystalline Silicon Nanomembranes and Their Use as Encapsulation Layers and Electrical Interfaces in Water-Soluble Electronics. AB - The chemistry that governs the dissolution of device-grade, monocrystalline silicon nanomembranes into benign end products by hydrolysis serves as the foundation for fully eco/biodegradable classes of high-performance electronics. This paper examines these processes in aqueous solutions with chemical compositions relevant to groundwater and biofluids. The results show that the presence of Si(OH)4 and proteins in these solutions can slow the rates of dissolution and that ion-specific effects associated with Ca2+ can significantly increase these rates. This information allows for effective use of silicon nanomembranes not only as active layers in eco/biodegradable electronics but also as water barriers capable of providing perfect encapsulation until their disappearance by dissolution. The time scales for this encapsulation can be controlled by introduction of dopants into the Si and by addition of oxide layers on the exposed surfaces.The former possibility also allows the doped silicon to serve as an electrical interface for measuring biopotentials, as demonstrated in fully bioresorbable platforms for in vivo neural recordings. This collection of findings is important for further engineering development of water-soluble classes of silicon electronics. PMID- 29178800 TI - Natural Attenuation and Anaerobic Benzene Detoxification Processes at a Chlorobenzene-Contaminated Industrial Site Inferred from Field Investigations and Microcosm Studies. AB - A five-year site investigation was conducted at a former chemical plant in Nanjing, China. The main contaminants were 1,2,4-trichlorobenzene (TCB) reaching concentrations up to 7300 MUg/L, dichlorobenzene (DCB) isomers, monochlorobenzene (MCB), and benzene. Over time, these contaminants naturally attenuated to below regulatory levels under anaerobic conditions. To confirm the transformation processes and to explore the mechanisms, a corresponding laboratory microcosm study was completed demonstrating that 1,2,4-TCB was dechlorinated to 1,2-DCB, 1,3-DCB, and 1,4-DCB in approximately 2%/10%/88% molar proportions. The DCB isomers were dechlorinated via MCB to benzene, and, finally, benzene was degraded under prevailing sulfate-reducing conditions. Dechlorination could not be attributed to known dechlorinators Dehalobacter or Dehalococcoides, while anaerobic benzene degradation was mediated by microbes affiliated to a Deltaproteobacterium ORM2, previously associated with this activity. Unidentified organic compounds, possibly aromatic compounds related to past on-site production processes, were fueling the dechlorination reactions in situ. The microcosm study confirmed transformation processes inferred from field data and provided needed assurance for natural attenuation. Activity-based microcosm studies are often omitted from site characterization in favor of rapid and less expensive molecular surveys. However, the value of microcosm studies for confirming transformation processes, establishing electron balances, assessing cocontaminant inhibition, and validating appropriate monitoring tools is clear. At complex sites impacted by multiple compounds with poorly characterized transformation mechanisms, activity assays provide valuable data to incorporate into the conceptual site model to most effectively inform remediation alternatives. PMID- 29178801 TI - Absolute Energy Level Positions in CdSe Nanostructures from Potential-Modulated Absorption Spectroscopy (EMAS). AB - Semiconductor nanostructures such as CdSe quantum dots and colloidal nanoplatelets exhibit remarkable optical properties, making them interesting for applications in optoelectronics and photocatalysis. For both areas of application a detailed understanding of the electronic structure is essential to achieve highly efficient devices. The electronic structure can be probed using the fact that optical properties of semiconductor nanoparticles are found to be extremely sensitive to the presence of excess charges that can for instance be generated by means of an electrochemical charge transfer via an electrode. Here we present the use of EMAS as a versatile spectroelectrochemical method to obtain absolute band edge positions of CdSe nanostructures versus a well-defined reference electrode under ambient conditions. In this, the spectral properties of the nanoparticles are monitored with respect to an applied electrochemical potential. We developed a bleaching model that yields the lowest electronic state in the conduction band of the nanostructures. A change in the band edge positions caused by quantum confinement is shown both for CdSe quantum dots and for colloidal nanoplatelets. In the case of CdSe quantum dots these findings are in good agreement with tight binding calculations. The method presented is not limited to CdSe nanostructures but can be used as a universal tool. Hence, this technique allows the determination of absolute band edge positions of a large variety of materials used in various applications. PMID- 29178802 TI - Rotamer-Specific Photoisomerization of Difluorostilbenes from Transient Absorption and Transient Raman Spectroscopy. AB - Photoisomerization of 2,2'-, 3,3'-, and 4,4'-difluorostilbene (F2, F3, F4, respectively) in n-hexane, perfluoro-n-hexane, and acetonitrile is studied with broadband transient absorption (TA) and femtosecond stimulated Raman (FSR) spectroscopy and by DFT/TDDFT calculations. F2 and F3 possess three rotamers (rotational isomers) each, while F4 has one single conformation only. These differences are reflected in TA and FSR spectra. Thus F4 reveals a monoexponential decay of TA with tau1 = 172 ps in n-hexane, as expected for a single species. For F2 and F3, the decays are biexponential in all solvents, corresponding to two distinctly discerned rotamers or rotamer fractions. Specifically, for F2 in n-hexane, tau1 = 357 ps (83%) and tau2 = 62 ps (17%), and for F3 in the same solvent, tau1 = 222 ps (57%), and tau2 = 81 ps (43%). The weights in brackets agree with theoretically estimated ground-state abundances of the rotamers. Furthermore, a global fit of the TA and FSR data allows us to extract the spectra of the pure rotamers. The Raman spectra of S0 and S1 are in qualitative agreement with calculations. PMID- 29178803 TI - NMR Chemical Shift of a Helium Atom as a Probe for Electronic Structure of FH, F , (FHF)-, and FH2. AB - In this work, we present the first results of outer electronic shell visualization by using a 3He atom as a probe particle. As model objects we have chosen F-, FH, and FH2+ species, as well as the hydrogen-bonded complex FH...F- at various H...F- distances (3.0, 2.5, 2.0, and 1.5 A and equilibrium at ca. 1.14 A). The interaction energy of investigated objects with helium atom (CCSD/aug-cc pVTZ) and helium atom chemical shift (B3LYP/pcS-2) surfaces were calculated, and their topological analysis was performed. For comparison, the results of standard quantum mechanical approaches to electronic shell visualization were presented (ESP, ELF, ED, ?2ED). We show that the Laplacian of helium chemical shift, ?2deltaHe, is sensitive to fluorine atom lone pair localization regions, and it can be used for the visualization of the outer electronic shell, which could be used to evaluate the proton accepting ability. The sensitivity of ?2deltaHe to lone pairs is preserved at distances as large as 2.0-2.5 A from the fluorine nucleus (in comparison with the distance to ESP minima, located at 1.0-1.5 A or maxima of ELF, which are as close as 0.6 A to the fluorine nucleus). PMID- 29178804 TI - Nanoporosity Change on Elastic Relaxation of Partially Folded Graphene Monoliths. AB - Fabrication of nanographene shows a promising route for production of designed porous carbons, which is indispensable for highly efficient molecular separation and energy storage applications. This process requires a better understanding of the mechanical properties of nanographene in their aggregated structure. We studied the structural and mechanical properties of nanographene monoliths compressed at 43 MPa over different times from 3 to 25 h. While in monoliths compressed over shorter time adsorption isotherms of Ar at 87 K or N2 at 77 K exhibited a prominent hysteresis due to presence of predominant mesopores, compression for long time induces a low pressure hysteresis. On the other hand, compression for 25 h increases the microporosity evaluated by Ar adsorption, not by N2 adsorption, indicating that 25 h compression rearranges the nanographene stacking structure to produce ultramicropores that can be accessible only for Ar. TEM, X-ray diffraction, and Raman spectroscopic studies indicated that the compression for 25 h unfolds double-bent-like structures, relaxing the unstable nanographene stacked structure formed on the initial compression without nanographene sheets collapse. This behavior stems from the highly elastic nature of the nanographenes. PMID- 29178805 TI - Zn2+ Induced Irreversible Aggregation, Stacking, and Leakage of Choline Phosphate Liposomes. AB - The interaction between lipids and metal ions is important for metal sensing, cellular signal transduction, and oxidative lipid damage. While most previous work overlooked the phosphate group of lipids for metal binding, we herein highlight its importance. Phosphocholine (PC) and its headgroup inversed choline phosphate (CP) lipids were used to prepare liposomes. From dynamic light scattering (DLS), Zn2+ causes significant aggregation or fusion of the CP liposomes, but not PC liposomes. The size change induced by Zn2+ is not fully reversed by adding EDTA, implying liposome fusion induced by Zn2+. Isothermal titration calorimetry (ITC) shows that binding between Zn2+ and CP liposomes is endothermic with a Kd of 110 MUM Zn2+, suggesting an entropy driven reaction likely due to the release of bound water. In comparison, no heat was detected by titrating Zn2+ into PC liposomes or Ca2+ into CP liposomes. Furthermore, Zn2+ causes a transient leakage of the CP liposomes, and further leakage is observed upon removing Zn2+ by EDTA. Transmission electron microscopy (TEM) with negative stained samples showed multilamellar CP lipid structures attributable to Zn2+ sandwiched between lipid bilayers, leading to a proposed reaction mechanism. This work provides an interesting system for studying metal interacting with terminal phosphate groups in liposomes, affecting the size, charge, and membrane integrity of the liposomes. PMID- 29178806 TI - Ligand-Assisted, One-Pot Synthesis of Rh-on-Cu Nanoscale Sea Urchins with High Density Interfaces for Boosting CO Oxidation. AB - Predictable synthesis of bimetallic nanocrystals with spatially controlled metal distributions offers a versatile route to the development of highly efficient nanocatalysts. Here we report a one-pot synthesis of super branched Rh-on-Cu nanoscale sea urchins (Rh-Cu NSUrs) with a high density of Cu-Rh interfaces by manipulating the ligand coordination chemistry. Structural analysis and UV-vis spectra reveal that ascorbic acid can serve as a Rh-selective coordination ligand in the nonaqueous synthesis to reverse the reduction potentials of Rh3+ and Cu2+ cations. The sequential reduction of Cu2+ and then Rh3+ cations, as well as the island epitaxial growth of Rh atoms on Cu cores, leads to the formation of Rh-on Cu nanostructures mimicking sea urchin. The size of the Cu cores and the density of Rh branches can both be facilely regulated by tuning the mole ratio of Cu to Rh. The Cu-Rh NSUrs show enhanced activity and stability in catalyzing CO oxidation, as the intrinsic Cu-Rh interfaces can act as catalytic hot spots through a bifunctional mechanism. The Cu-Rh two-component system can separate the adsorption and activation of CO and O2 on the Rh and Cu surfaces, respectively, accelerating the generation of CO2 at the interfaces. PMID- 29178807 TI - Conductive Tungsten Oxide Nanosheets for Highly Efficient Hydrogen Evolution. AB - Exploring efficient and economical electrocatalysts for hydrogen evolution reaction is of great significance for water splitting on an industrial scale. Tungsten oxide, WO3, has been long expected to be a promising non-precious-metal electrocatalyst for hydrogen production. However, the poor intrinsic activity of this material hampers its development. Herein, we design a highly efficient hydrogen evolution electrocatalyst via introducing oxygen vacancies into WO3 nanosheets. Our first-principles calculations demonstrate that the gap states introduced by O vacancies make WO3 act as a degenerate semiconductor with high conductivity and desirable hydrogen adsorption free energy. Experimentally, we prepared WO3 nanosheets rich in oxygen vacancies via a liquid exfoliation, which indeed exhibits the typical character of a degenerate semiconductor. When evaluated by hydrogen evolution, the nanosheets display superior performance with a small overpotential of 38 mV at 10 mA cm-2 and a low Tafel slope of 38 mV dec 1. This work opens an effective route to develop conductive tungsten oxide as a potential alternative to the state-of-the-art platinum for hydrogen evolution.

The vertical transistor device consists of a connected organic nanotriode array obtained using porous anodized alumina membranes of pore density ~ 109 pores/cm2. In this structure, a collector-emitter diode gives rise to a space charge limited current, which can be controlled by a third intermediate porous base electrode to give transistor-like characteristics. We study the response characteristics along with 2D device simulations of this novel structure to indicate key parameters involved in the underlying mechanism. Device operation at single transistor level is verified by conductive atomic force microscopy, and the inherent short switching time scales of the vertical structure device is also demonstrated. PMID- 29178809 TI - Quantum Confinement of Hybrid Charge Transfer Excitons in GaN/InGaN/Organic Semiconductor Quantum Wells. AB - We investigate hybrid charge transfer exciton (HCTE) confinement in organic inorganic (OI) quantum wells (QWs) comprising a thin InGaN layer bound on one side by GaN and on the other by the organic semiconductors, tetraphenyldibenzoperiflanthene (DBP) or 4,4'-bis(N-carbazolyl)-1,1'-biphenyl (CBP). A binding energy of 10 meV is calculated for the Coulombically bound free HCTE state between a delocalized electron in GaN and a hole localized in DBP. The binding energy of the HCTE increases to 165 meV when the electron is confined to a 1.5 nm In0.21Ga0.79N QW (HCTEQW). The existence of the HCTEQW is confirmed by measuring the voltage-dependent DBP exciton dissociation yield at the OI heterojunction in the QW devices that decrease with increasing In concentration and decreasing electric field, matching the trends predicted by Poole-Frenkel emission. Combining spectroscopic measurements with optical models, we find that 14 +/- 3% of the excitons that reach the GaN/DBP heterojunction form HCTEs and dissociate into free charges, while the remainder recombine. A high nonradiative recombination rate through defect states at the heterointerface account for the lack of observation of HCTEQW photoluminescence from GaN/InGaN/CBP QWs at temperatures as low as 10 K. PMID- 29178810 TI - Nanoscale-Agglomerate-Mediated Heterogeneous Nucleation. AB - Water vapor condensation on hydrophobic surfaces has received much attention due to its ability to rapidly shed water droplets and enhance heat transfer, anti icing, water harvesting, energy harvesting, and self-cleaning performance. However, the mechanism of heterogeneous nucleation on hydrophobic surfaces remains poorly understood and is attributed to defects in the hydrophobic coating exposing the high surface energy substrate. Here, we observe the formation of high surface energy nanoscale agglomerates on hydrophobic coatings after condensation/evaporation cycles in ambient conditions. To investigate the deposition dynamics, we studied the nanoscale agglomerates as a function of condensation/evaporation cycles via optical and field emission scanning electron microscopy (FESEM), microgoniometric contact angle measurements, nucleation statistics, and energy dispersive X-ray spectroscopy (EDS). The FESEM and EDS results indicated that the nanoscale agglomerates stem from absorption of sulfuric acid based aerosol particles inside the droplet and adsorption of volatile organic compounds such as methanethiol (CH3SH), dimethyl disulfide (CH3SSCH), and dimethyl trisulfide (CH3SSSCH3) on the liquid-vapor interface during water vapor condensation, which act as preferential sites for heterogeneous nucleation after evaporation. The insights gained from this study elucidate fundamental aspects governing the behavior of both short- and long-term heterogeneous nucleation on hydrophobic surfaces, suggest previously unexplored microfabrication and air purification techniques, and present insights into the challenges facing the development of durable dropwise condensing surfaces.

However, less is known about semantic priming in scene context. In this study, 24 month-olds with high and low vocabulary skills were presented with visual scenes (e.g., kitchen) followed by semantically consistent (e.g., spoon) or inconsistent (e.g., bed) spoken words. Inconsistent scene-word pairs evoked a larger N400 component over the frontal areas. Low-producers presented a larger N400 over the right while high-producers over the left frontal areas. Our results suggest that contextual information facilitates word processing in young children. Additionally, children with different linguistic skills activate different neural structures. PMID- 29178813 TI - The Threat of Synthetic Smallpox: European Perspectives. AB - This article explores how advances in synthetic biology, and the potential threat of deliberately recreating and spreading smallpox, are affecting the multilateral debate on the remaining variola virus stocks. It draws on in-depth, semi structured interviews with 10 high-profile, European-based experts in biosecurity and synthetic biology. Four overarching themes affecting the retention or destruction debate are discussed, relating to biosecurity, dangerous knowledge, accidental releases, and eradication. We conclude that while synthetic biology seems to affect all the main discourses in the variola stocks debate, a range of views is present and it is not apparent that advances in synthetic biology are causing a shift toward either retention or destruction of the stocks.

AB - Extracellular biophysical cues have a profound influence on a wide range of cell behaviors, including growth, motility, differentiation, apoptosis, gene expression, adhesion, and signal transduction. Cells not only respond to definitively mechanical cues from the extracellular matrix (ECM) but can also sometimes alter the mechanical properties of the matrix and hence influence subsequent matrix-based cues in both physiological and pathological processes. Interactions between cells and materials in vitro can modify cell phenotype and ECM structure, whether intentionally or inadvertently. Interactions between cell and matrix mechanics in vivo are of particular importance in a wide variety of disorders, including cancer, central nervous system injury, fibrotic diseases, and myocardial infarction. Both the in vitro and in vivo effects of this coupling between mechanics and biology hold important implications for clinical applications. PMID- 29178814 TI - Natural Hazards Preparedness in Taiwan: A Comparison Between Households With and Without Disabled Members. AB - People with disabilities are one of the most vulnerable groups to natural hazards. Preparedness is critical to protect life and reduce disaster impact. This article discusses the knowledge of the disaster preparedness behaviors of people with disabilities using updated, representative data from Taiwan (2013 Taiwan Social Change Survey), with a comparison to households without disabled members. The adoption of 6 preparedness activities-relocating vehicles or valuable things to a safer place, purchasing insurance, securing furniture, preparing an emergency kit, planning evacuation, and participating in drills-are used separately as dependent variables. The unadjusted results from Logit regression models show that the households with disabled members are less likely to prepare emergency kits and to plan evacuation. But with the adjustment of risk perception (probability, consequence, worrisome) and other factors-experience of earthquake and typhoon hazards, home ownership status, whether there are children in the home, perceived social status, family income, gender, age, education attainment, and religious status-the differences in adopting all 6 preparedness activities between households with disabled members and households without disabled members become nonsignificant. Finally, the contribution, limitations, and practice implications of this article are discussed. PMID- 29178815 TI - Central Core Laboratory versus Site Interpretation of Coronary CT Angiography: Agreement and Association with Cardiovascular Events in the PROMISE Trial. AB - Purpose To assess concordance and relative prognostic utility between central core laboratory and local site interpretation for significant coronary artery disease (CAD) and cardiovascular events. Materials and Methods In the Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) trial, readers at 193 North American sites interpreted coronary computed tomographic (CT) angiography as part of the clinical evaluation of stable chest pain. Readers at a central core laboratory also interpreted CT angiography blinded to clinical data, site interpretation, and outcomes. Significant CAD was defined as stenosis greater than or equal to 50%; cardiovascular events were defined as a composite of cardiovascular death or myocardial infarction. Results In 4347 patients (51.8% women; mean age +/- standard deviation, 60.4 years +/- 8.2), core laboratory and site interpretations were discordant in 16% (683 of 4347), most commonly because of a finding of significant CAD by site but not by core laboratory interpretation (80%, 544 of 683). Overall, core laboratory interpretation resulted in 41% fewer patients being reported as having significant CAD (14%, 595 of 4347 vs 23%, 1000 of 4347; P < .001). Over a median follow-up period of 25 months, 1.3% (57 of 4347) sustained myocardial infarction or cardiovascular death. The C statistic for future myocardial infarction or cardiovascular death was 0.61 (95% confidence interval [CI]: 0.54, 0.68) for the core laboratory and 0.63 (95% CI: 0.56, 0.70) for the sites. Conclusion Compared with interpretation by readers at 193 North American sites, standardized core laboratory interpretation classified 41% fewer patients as having significant CAD.

PMID- 29178816 TI - A Pivotal Study of Optoacoustic Imaging to Diagnose Benign and Malignant Breast Masses: A New Evaluation Tool for Radiologists. AB - Purpose To compare the diagnostic utility of an investigational optoacoustic imaging device that fuses laser optical imaging (OA) with grayscale ultrasonography (US) to grayscale US alone in differentiating benign and malignant breast masses. Materials and Methods This prospective, 16-site study of 2105 women (study period: 12/21/2012 to 9/9/2015) compared Breast Imaging Reporting and Data System (BI-RADS) categories assigned by seven blinded independent readers to benign and malignant breast masses using OA/US versus US alone. BI-RADS 3, 4, or 5 masses assessed at diagnostic US with biopsy-proven histologic findings and BI-RADS 3 masses stable at 12 months were eligible. Independent readers reviewed US images obtained with the OA/US device, assigned a probability of malignancy (POM) and BI-RADS category, and locked results. The same independent readers then reviewed OA/US images, scored OA features, and assigned OA/US POM and a BI-RADS category. Specificity and sensitivity were calculated for US and OA/US. Benign and malignant mass upgrade and downgrade rates, positive and negative predictive values, and positive and negative likelihood ratios were compared. Results Of 2105 consented subjects with 2191 masses, 100 subjects (103 masses) were analyzed separately as a training population and excluded. An additional 202 subjects (210 masses) were excluded due to technical failures or incomplete imaging, 72 subjects (78 masses) due to protocol deviations, and 41 subjects (43 masses) due to high-risk histologic results. Of 1690 subjects with 1757 masses (1079 [61.4%] benign and 678 [38.6%] malignant masses), OA/US downgraded 40.8% (3078/7535) of benign mass reads, with a specificity of 43.0% (3242/7538, 99% confidence interval [CI]: 40.4%, 45.7%) for OA/US versus 28.1% (2120/7543, 99% CI: 25.8%, 30.5%) for the internal US of the OA/US device. OA/US exceeded US in specificity by 14.9% (P < .0001; 99% CI: 12.9, 16.9%). Sensitivity for biopsied malignant masses was 96.0% (4553/4745, 99% CI: 94.5%, 97.0%) for OA/US and 98.6% (4680/4746, 99% CI: 97.8%, 99.1%) for US (P < .0001). The negative likelihood ratio of 0.094 for OA/US indicates a negative examination can reduce a maximum US-assigned pretest probability of 17.8% (low BI RADS 4B) to a posttest probability of 2% (BI-RADS 3). Conclusion OA/US increases the specificity of breast mass assessment compared with the device internal grayscale US alone. Online supplemental material is available for this article. (c) RSNA, 2017. PMID- 29178817 TI - Conditional Degrons for Controlling Protein Expression at the Protein Level. AB - The conditional depletion of a protein of interest (POI) is useful not only for loss-of-function studies, but also for the modulation of biological pathways. Technologies that work at the level of DNA, mRNA, and protein are available for temporal protein depletion. Compared with technologies targeting the pretranslation steps, direct protein depletion (or protein knockdown approaches) is advantageous in terms of specificity, reversibility, and time required for depletion, which can be achieved by fusing a POI with a protein domain called a degron that induces rapid proteolysis of the fusion protein. Conditional degrons can be activated or inhibited by temperature, small molecules, light, or the expression of another protein. The conditional degron-based technologies currently available are described and discussed. PMID- 29178818 TI - Transcriptional Regulation in Archaea: From Individual Genes to Global Regulatory Networks. AB - Archaea are major contributors to biogeochemical cycles, possess unique metabolic capabilities, and resist extreme stress. To regulate the expression of genes encoding these unique programs, archaeal cells use gene regulatory networks (GRNs) composed of transcription factor proteins and their target genes. Recent developments in genetics, genomics, and computational methods used with archaeal model organisms have enabled the mapping and prediction of global GRN structures. Experimental tests of these predictions have revealed the dynamical function of GRNs in response to environmental variation. Here, we review recent progress made in this area, from investigating the mechanisms of transcriptional regulation of individual genes to small-scale subnetworks and genome-wide global networks. At each level, archaeal GRNs consist of a hybrid of bacterial, eukaryotic, and uniquely archaeal mechanisms. We discuss this theme from the perspective of the role of individual transcription factors in genome-wide regulation, how these proteins interact to compile GRN topological structures, and how these topologies lead to emergent, high-level GRN functions. We conclude by discussing how systems biology approaches are a fruitful avenue for addressing remaining challenges, such as discovering gene function and the evolution of GRNs. PMID- 29178819 TI - Mas-Related G Protein-Coupled Receptors and the Biology of Itch Sensation. AB - Chronic, persistent itch is a devastating symptom that causes much suffering. In recent years, there has been great progress made in understanding the molecules, cells, and circuits underlying itch sensation. Once thought to be carried by pain sensing neurons, itch is now believed to be capable of being transmitted by dedicated sensory labeled lines. Members of the Mas-related G protein-coupled receptor (Mrgpr) family demarcate an itch-specific labeled line in the peripheral nervous system. In the spinal cord, the expression of other proteins identifies additional populations of itch-dedicated sensory neurons. However, as evidence for labeled-line coding has mounted, studies promoting alternative itch-coding strategies have emerged, complicating our understanding of the neural basis of itch. In this review, we cover the molecules, cells, and circuits related to understanding the neural basis of itch, with a focus on the role of Mrgprs in mediating itch sensation. PMID- 29178820 TI - Nucleases Acting at Stalled Forks: How to Reboot the Replication Program with a Few Shortcuts. AB - In a lifetime, a human being synthesizes approximately 2*1016 meters of DNA, a distance that corresponds to 130,000 times the distance between the Earth and the Sun. This daunting task is executed by thousands of replication forks, which progress along the chromosomes and frequently stall when they encounter DNA lesions, unusual DNA structures, RNA polymerases, or tightly-bound protein complexes. To complete DNA synthesis before the onset of mitosis, eukaryotic cells have evolved complex mechanisms to process and restart arrested forks through the coordinated action of multiple nucleases, topoisomerases, and helicases. In this review, we discuss recent advances in understanding the role and regulation of nucleases acting at stalled forks with a focus on the nucleolytic degradation of nascent DNA, a process commonly referred to as fork resection. We also discuss the effects of deregulated fork resection on genomic instability and on the unscheduled activation of the interferon response under replication stress conditions. PMID- 29178821 TI - Mosaicism in Cutaneous Disorders. AB - Genetic mosaicism arises when a zygote harbors two or more distinct genotypes, typically due to de novo, somatic mutation during embryogenesis. The clinical manifestations largely depend on the differentiation status of the mutated cell; earlier mutations target pluripotent cells and generate more widespread disease affecting multiple organ systems. If gonadal tissue is spared-as in somatic genomic mosaicism-the mutation and its effects are limited to the proband, whereas mosaicism also affecting the gametes, such as germline or gonosomal mosaicism, is transmissible. Mosaicism is easily appreciated in cutaneous disorders, as phenotypically distinct mutant cells often give rise to lesions in patterns determined by the affected cell type. Genetic investigation of cutaneous mosaic disorders has identified pathways central to disease pathogenesis, revealing novel therapeutic targets. In this review, we discuss examples of cutaneous mosaicism, approaches to gene discovery in these disorders, and insights into molecular pathobiology that have potential for clinical translation. PMID- 29178822 TI - A modified GC-specific MAKER gene annotation method reveals improved and novel gene predictions of high and low GC content in Oryza sativa. AB - BACKGROUND: Accurate structural annotation depends on well-trained gene prediction programs. Training data for gene prediction programs are often chosen randomly from a subset of high-quality genes that ideally represent the variation found within a genome. One aspect of gene variation is GC content, which differs across species and is bimodal in grass genomes. When gene prediction programs are trained on a subset of grass genes with random GC content, they are effectively being trained on two classes of genes at once, and this can be expected to result in poor results when genes are predicted in new genome sequences. RESULTS: We find that gene prediction programs trained on grass genes with random GC content do not completely predict all grass genes with extreme GC content. We show that gene prediction programs that are trained with grass genes with high or low GC content can make both better and unique gene predictions compared to gene prediction programs that are trained on genes with random GC content. By separately training gene prediction programs with genes from multiple GC ranges and using the programs within the MAKER genome annotation pipeline, we were able to improve the annotation of the Oryza sativa genome compared to using the standard MAKER annotation protocol. Gene structure was improved in over 13% of genes, and 651 novel genes were predicted by the GC-specific MAKER protocol. CONCLUSIONS: We present a new GC-specific MAKER annotation protocol to predict new and improved gene models and assess the biological significance of this method in Oryza sativa. We expect that this protocol will also be beneficial for gene prediction in any organism with bimodal or other unusual gene GC content. PMID- 29178823 TI - Genetic relatedness of Vibrio cholerae isolates within and between households during outbreaks in Dhaka, Bangladesh. AB - BACKGROUND: Household contacts of cholera patients have a 100 times higher risk of developing a cholera infection than the general population. To compare the genetic relatedness of clinical and water source Vibrio cholerae isolates from cholera patients' households across three outbreaks, we analyzed these isolates using whole-genome-sequencing (WGS) and multilocus variable-number tandem-repeat analysis (MLVA). RESULTS: The WGS analyses revealed that 80% of households had source water isolates that were more closely related to clinical isolates from the same household than to any other isolates. While in another 20% of households an isolate from a person was more closely related to clinical isolates from another household than to source water isolates from their own household. The mean pairwise differences in single nucleotide-variant (SNV) counts for isolates from the same household were significantly lower than those for different households (2.4 vs. 7.7 p < 0.0001), and isolates from the same outbreak had significantly fewer mean pairwise differences compared to isolates from different outbreaks (mean: 6.2 vs. 8.0, p < 0.0001). Based on MLVA in outbreak 1, we observed that the majority of households had clinical isolates with MLVA genotypes related to other clinical isolates and unrelated to water source isolates from the same household. While in outbreak 3, there were different MLVA genotypes between households, however within the majority of households, the clinical and water source isolates had the same MLVA genotypes. The beginning of outbreak 2 resembled outbreak 1 and the latter part resembled outbreak 3. We validated our use of MLVA by comparing it to WGS. Isolates with the identical MLVA genotype had significantly fewer mean pairwise SNV differences than those isolates with different MLVA genotypes (mean: 4.8 vs. 7.7, p < 0.0001). Furthermore, consistent with WGS results, the number of pairwise differences in the five MLVA loci for isolates within the same household was significantly lower than isolates from different households (mean: 1.6 vs. 3.0, p < 0.0001). CONCLUSION: These results suggest that transmission patterns for cholera are a combination of person-to-person and water-to-person cholera transmission with the proportions of the two modes varying within and between outbreaks. PMID- 29178824 TI - Transcriptome analysis of avian reovirus-mediated changes in gene expression of normal chicken fibroblast DF-1 cells. AB - BACKGROUND: Avian reovirus (ARV) is an important poultry pathogen that can cause immunosuppression. In this study, RNA-Seq technology was applied to investigate the transcriptome-wide changes of DF-1 cells upon ARV infection at the middle stage. RESULTS: Total RNA of ARV-infected or mock-infected samples at 10 and 18 h post infection (hpi) was extracted to build RNA-Seq datasets. Analysis of the sequencing data revealed that the expressions of numerous genes were altered, and a panel of differentially expressed genes were confirmed with RT-qPCR. At 10 hpi, 104 genes were down-regulated and 64 were up-regulated, while the expressions of 47 genes were increased and only one was down-regulated, which may play a role in retinoic acid biosynthesis, at 18 hpi in the ARV-infected cells. The similar profiles of up-regulated genes between the two groups of infected cells suggest that ARV infection activated a prolonged antiviral response of host cells. Alternative splicing analysis found no significantly changed events altered by ARV infection. CONCLUSIONS: Overall, the differential expression profile presented in this study can be used to expand our understanding of the comprehensive interactions between ARV and the host cells, and may be helpful for us to reveal the pathogenic mechanism on the molecular level. PMID- 29178825 TI - Phylogenetic relationships of cone snails endemic to Cabo Verde based on mitochondrial genomes. AB - BACKGROUND: Due to their great species and ecological diversity as well as their capacity to produce hundreds of different toxins, cone snails are of interest to evolutionary biologists, pharmacologists and amateur naturalists alike. Taxonomic identification of cone snails still relies mostly on the shape, color, and banding patterns of the shell. However, these phenotypic traits are prone to homoplasy. Therefore, the consistent use of genetic data for species delimitation and phylogenetic inference in this apparently hyperdiverse group is largely wanting. Here, we reconstruct the phylogeny of the cones endemic to Cabo Verde archipelago, a well-known radiation of the group, using mitochondrial (mt) genomes. RESULTS: The reconstructed phylogeny grouped the analyzed species into two main clades, one including Kalloconus from West Africa sister to Trovaoconus from Cabo Verde and the other with a paraphyletic Lautoconus due to the sister group relationship of Africonus from Cabo Verde and Lautoconus ventricosus from Mediterranean Sea and neighboring Atlantic Ocean to the exclusion of Lautoconus endemic to Senegal (plus Lautoconus guanche from Mauritania, Morocco, and Canary Islands). Within Trovaoconus, up to three main lineages could be distinguished. The clade of Africonus included four main lineages (named I to IV), each further subdivided into two monophyletic groups. The reconstructed phylogeny allowed inferring the evolution of the radula in the studied lineages as well as biogeographic patterns. The number of cone species endemic to Cabo Verde was revised under the light of sequence divergence data and the inferred phylogenetic relationships. CONCLUSIONS: The sequence divergence between continental members of the genus Kalloconus and island endemics ascribed to the genus Trovaoconus is low, prompting for synonymization of the latter. The genus Lautoconus is paraphyletic. Lautoconus ventricosus is the closest living sister group of genus Africonus. Diversification of Africonus was in allopatry due to the direct development nature of their larvae and mainly triggered by eustatic sea level changes during the Miocene-Pliocene. Our study confirms the diversity of cone endemic to Cabo Verde but significantly reduces the number of valid species. Applying a sequence divergence threshold, the number of valid species within the sampled Africonus is reduced to half.

PMID- 29178827 TI - Genome-wide segregation of single nucleotide and structural variants into single cancer cells. AB - BACKGROUND: Single-cell genome sequencing provides high-resolution details of the clonal genomic modifications that occur during cancer initiation, progression, and ongoing evolution as patients undergo treatment. One limitation of current single-cell sequencing strategies is a suboptimal capacity to detect all classes of single-nucleotide and structural variants in the same cells. RESULTS: Here we present a new approach for determining comprehensive variant profiles of single cells using a microfluidic amplicon-based strategy to detect structural variant breakpoint sequences instead of using relative read depth to infer copy number changes. This method can reconstruct the clonal architecture and mutational history of a malignancy using all classes and sizes of somatic variants, providing more complete details of the temporal changes in mutational classes and processes that led to the development of a malignant neoplasm. Using this approach, we interrogated cells from a patient with leukemia, determining that processes producing structural variation preceded single nucleotide changes in the development of that malignancy. CONCLUSIONS: All classes and sizes of genomic variants can be efficiently detected in single cancer cells using our new method, enabling the ordering of distinct classes of mutations during tumor evolution. PMID- 29178828 TI - CrusTF: a comprehensive resource of transcriptomes for evolutionary and functional studies of crustacean transcription factors. AB - BACKGROUND: Crustacea, the second largest subphylum of Arthropoda, includes species of major ecological and economic importance, such as crabs, lobsters, crayfishes, shrimps, and barnacles. With the rapid development of crustacean aquaculture and biodiversity loss, understanding the gene regulatory mechanisms of growth, reproduction, and development of crustaceans is crucial to both aquaculture development and biodiversity conservation of this group of organisms. In these biological processes, transcription factors (TFs) play a vital role in regulating gene expression. However, crustacean transcription factors are still largely unknown, because the lack of complete genome sequences of most crustacean species hampers the studies on their transcriptional regulation on a system-wide scale. Thus, the current TF databases derived from genome sequences contain TF information for only a few crustacean species and are insufficient to elucidate the transcriptional diversity of such a large animal group. RESULTS: Our database CrusTF ( http://qinlab.sls.cuhk.edu.hk/CrusTF ) provides comprehensive information for evolutionary and functional studies on the crustacean transcriptional regulatory system. CrusTF fills the knowledge gap of transcriptional regulation in crustaceans by exploring publicly available and newly sequenced transcriptomes of 170 crustacean species and identifying 131,941 TFs within 63 TF families. CrusTF features three categories of information: sequence, function, and evolution of crustacean TFs. The database enables searching, browsing and downloading of crustacean TF sequences. CrusTF infers DNA binding motifs of crustacean TFs, thus facilitating the users to predict potential downstream TF targets. The database also presents evolutionary analyses of crustacean TFs, which improve our understanding of the evolution of transcriptional regulatory systems in crustaceans. CONCLUSIONS: Given the importance of TF information in evolutionary and functional studies on transcriptional regulatory systems of crustaceans, this database will constitute a key resource for the research community of crustacean biology and evolutionary biology. Moreover, CrusTF serves as a model for the construction of TF database derived from transcriptome data. A similar approach could be applied to other groups of organisms, for which transcriptomes are more readily available than genomes. PMID- 29178829 TI - ENCoRE: an efficient software for CRISPR screens identifies new players in extrinsic apoptosis. AB - BACKGROUND: As CRISPR/Cas9 mediated screens with pooled guide libraries in somatic cells become increasingly established, an unmet need for rapid and accurate companion informatics tools has emerged. We have developed a lightweight and efficient software to easily manipulate large raw next generation sequencing datasets derived from such screens into informative relational context with graphical support. The advantages of the software entitled ENCoRE (Easy NGS-to Gene CRISPR REsults) include a simple graphical workflow, platform independence, local and fast multithreaded processing, data pre-processing and gene mapping with custom library import. RESULTS: We demonstrate the capabilities of ENCoRE to interrogate results from a pooled CRISPR cellular viability screen following Tumor Necrosis Factor-alpha challenge. The results not only identified stereotypical players in extrinsic apoptotic signaling but two as yet uncharacterized members of the extrinsic apoptotic cascade, Smg7 and Ces2a. We further validated and characterized cell lines containing mutations in these genes against a panel of cell death stimuli and involvement in p53 signaling. CONCLUSIONS: In summary, this software enables bench scientists with sensitive data or without access to informatic cores to rapidly interpret results from large scale experiments resulting from pooled CRISPR/Cas9 library screens. PMID- 29178830 TI - Mosaic autosomal aneuploidies are detectable from single-cell RNAseq data. AB - BACKGROUND: Aneuploidies are copy number variants that affect entire chromosomes. They are seen commonly in cancer, embryonic stem cells, human embryos, and in various trisomic diseases. Aneuploidies frequently affect only a subset of cells in a sample; this is known as "mosaic" aneuploidy. A cell that harbours an aneuploidy exhibits disrupted gene expression patterns which can alter its behaviour. However, detection of aneuploidies using conventional single-cell DNA sequencing protocols is slow and expensive. METHODS: We have developed a method that uses chromosome-wide expression imbalances to identify aneuploidies from single-cell RNA-seq data. The method provides quantitative aneuploidy calls, and is integrated into an R software package available on GitHub and as an Additional file of this manuscript. RESULTS: We validate our approach using data with known copy number, identifying the vast majority of aneuploidies with a low rate of false discovery. We show further support for the method's efficacy by exploiting allele-specific gene expression levels, and differential expression analyses. CONCLUSIONS: The method is quick and easy to apply, straightforward to interpret, and represents a substantial cost saving compared to single-cell genome sequencing techniques. However, the method is less well suited to data where gene expression is highly variable. The results obtained from the method can be used to investigate the consequences of aneuploidy itself, or to exclude aneuploidy affected expression values from conventional scRNA-seq data analysis. PMID- 29178831 TI - Software for rapid time dependent ChIP-sequencing analysis (TDCA). AB - BACKGROUND: Chromatin immunoprecipitation followed by DNA sequencing (ChIP-seq) and associated methods are widely used to define the genome wide distribution of chromatin associated proteins, post-translational epigenetic marks, and modifications found on DNA bases. An area of emerging interest is to study time dependent changes in the distribution of such proteins and marks by using serial ChIP-seq experiments performed in a time resolved manner. Despite such time resolved studies becoming increasingly common, software to facilitate analysis of such data in a robust automated manner is limited. RESULTS: We have designed software called Time-Dependent ChIP-Sequencing Analyser (TDCA), which is the first program to automate analysis of time-dependent ChIP-seq data by fitting to sigmoidal curves. We provide users with guidance for experimental design of TDCA for modeling of time course (TC) ChIP-seq data using two simulated data sets. Furthermore, we demonstrate that this fitting strategy is widely applicable by showing that automated analysis of three previously published TC data sets accurately recapitulates key findings reported in these studies. Using each of these data sets, we highlight how biologically relevant findings can be readily obtained by exploiting TDCA to yield intuitive parameters that describe behavior at either a single locus or sets of loci. TDCA enables customizable analysis of user input aligned DNA sequencing data, coupled with graphical outputs in the form of publication-ready figures that describe behavior at either individual loci or sets of loci sharing common traits defined by the user. TDCA accepts sequencing data as standard binary alignment map (BAM) files and loci of interest in browser extensible data (BED) file format. CONCLUSIONS: TDCA accurately models the number of sequencing reads, or coverage, at loci from TC ChIP-seq studies or conceptually related TC sequencing experiments. TC experiments are reduced to intuitive parametric values that facilitate biologically relevant data analysis, and the uncovering of variations in the time-dependent behavior of chromatin. TDCA automates the analysis of TC ChIP-seq experiments, permitting researchers to easily obtain raw and modeled data for specific loci or groups of loci with similar behavior while also enhancing consistency of data analysis of TC data within the genomics field. PMID- 29178832 TI - Is the information of systematic reviews published in nursing journals up-to date? a cross-sectional study. AB - BACKGROUND: An up-to-date systematic review is important for researchers to decide whether to embark on new research or continue supporting ongoing studies. The aim of this study is to examine the time taken between the last search, submission, acceptance and publication dates of systematic reviews published in nursing journals. METHODS: Nursing journals indexed in Journal Citation Reports were first identified. Thereafter, systematic reviews published in these journals in 2014 were extracted from three databases. The quality of the systematic reviews were evaluated by the AMSTAR. The last search, submission, acceptance, online publication, full publication dates and other characteristics of the systematic reviews were recorded. The time taken between the five dates was then computed. Descriptive statistics were used to summarize the time differences; non parametric statistics were used to examine the association between the time taken from the last search and full publication alongside other potential factors, including the funding support, submission during holiday periods, number of records retrieved from database, inclusion of meta-analysis, and quality of the review. RESULTS: A total of 107 nursing journals were included in this study, from which 1070 articles were identified through the database search. After screening for eligibility, 202 systematic reviews were included in the analysis. The quality of these reviews was low with the median score of 3 out of 11. A total of 172 (85.1%), 72 (35.6%), 153 (75.7%) and 149 (73.8%) systematic reviews provided their last search, submission, acceptance and online published dates respectively. The median numbers of days taken from the last search to acceptance and to full publication were, respectively, 393 (IQR: 212-609) and 669 (427-915) whereas that from submission to full publication was 365 (243-486). Moreover, the median number of days from the last search to submission and from submission to online publication were 167.5 (53.5-427) and 153 (92-212), respectively. No significant association were revealed between the time lag and those potential factors. CONCLUSION: The median time from the last search to acceptance for systematic reviews published in nursing journals was 393 days. Readers for systematic reviews are advised to check the time taken from the last search date of the reviews in order to ensure that up-to-date evidence is consulted for effective clinical decision-making. PMID- 29178833 TI - Genome-wide association studies of fertility and calving traits in Brown Swiss cattle using imputed whole-genome sequences. AB - BACKGROUND: The detection of quantitative trait loci has accelerated with recent developments in genomics. The introduction of genomic selection in combination with sequencing efforts has made a large amount of genotypic data available. Functional traits such as fertility and calving traits have been included in routine genomic estimation of breeding values making large quantities of phenotypic data available for these traits. This data was used to investigate the genetics underlying fertility and calving traits and to identify potentially causative genomic regions and variants. We performed genome-wide association studies for 13 functional traits related to female fertility as well as for direct and maternal calving ease based on imputed whole-genome sequences. Deregressed breeding values from ~1000-5000 bulls per trait were used to test for associations with approximately 10 million imputed sequence SNPs. RESULTS: We identified a QTL on BTA17 associated with non-return rate at 56 days and with interval from first to last insemination. We found two significantly associated non-synonymous SNPs within this QTL region. Two more QTL for fertility traits were identified on BTA25 and 29. A single QTL was identified for maternal calving traits on BTA13 whereas three QTL on BTA19, 21 and 25 were identified for direct calving traits. The QTL on BTA19 co-localizes with the reported BH2 haplotype. The QTL on BTA25 is concordant for fertility and calving traits and co-localizes with a QTL previously reported to influence stature and related traits in Brown Swiss dairy cattle. CONCLUSION: The detection of QTL and their causative variants remains challenging. Combining comprehensive phenotypic data with imputed whole genome sequences seems promising. We present a QTL on BTA17 for female fertility in dairy cattle with two significantly associated non-synonymous SNPs, along with five additional QTL for fertility traits and calving traits. For all of these we fine mapped the regions and suggest candidate genes and candidate variants. PMID- 29178834 TI - Association of variation in the sugarcane transcriptome with sugar content. AB - BACKGROUND: Sugarcane is a major crop of the tropics cultivated mainly for its high sucrose content. The crop is genetically less explored due to its complex polyploid genome. Sucrose synthesis and accumulation are complex processes influenced by physiological, biochemical and genetic factors, and the growth environment. The recent focus on the crop for fibre and biofuel has led to a renewed interest on understanding the molecular basis of sucrose and biomass traits. This transcriptome study aimed to identify genes that are associated with and differentially regulated during sucrose synthesis and accumulation in the mature stage of sugarcane. Patterns of gene expression in high and low sugar genotypes as well as mature and immature culm tissues were studied using RNA-Seq of culm transcriptomes. RESULTS: In this study, 28 RNA-Seq libraries from 14 genotypes of sugarcane differing in their sucrose content were used for studying the transcriptional basis of sucrose accumulation. Differential gene expression studies were performed using SoGI (Saccharum officinarum Gene Index, 3.0), SAS (sugarcane assembled sequences) of sugarcane EST database (SUCEST) and SUGIT, a sugarcane Iso-Seq transcriptome database. In total, about 34,476 genes were found to be differentially expressed between high and low sugar genotypes with the SoGI database, 20,487 genes with the SAS database and 18,543 genes with the SUGIT database at FDR < 0.01, using the Baggerley's test. Further, differential gene expression analyses were conducted between immature (top) and mature (bottom) tissues of the culm. The DEGs were functionally annotated using GO classification and the genes consistently associated with sucrose accumulation were identified. CONCLUSIONS: The large number of DEGs may be due to the large number of genes that influence sucrose content or are regulated by sucrose content. These results indicate that apart from being a primary metabolite and storage and transport sugar, sucrose may serve as a signalling molecule that regulates many aspects of growth and development in sugarcane. Further studies are needed to confirm if sucrose regulates the expression of the identified DEGs or vice versa. The DEGs identified in this study may lead to identification of genes/pathways regulating sucrose accumulation and/or regulated by sucrose levels in sugarcane. We propose identifying the master regulators of sucrose if any in the future. PMID- 29178835 TI - Phylogenetics of subtribe Orchidinae s.l. (Orchidaceae; Orchidoideae) based on seven markers (plastid matK, psaB, rbcL, trnL-F, trnH-psba, and nuclear nrITS, Xdh): implications for generic delimitation. AB - BACKGROUND: Subtribe Orchidinae (Orchidaceae, Orchidoideae) are a nearly cosmopolitan taxon of terrestrial orchids, comprising about 1800 species in 47 to 60 genera. Although much progress has been made in recent years of phylogenetics of Orchidinae, considerable problems remain to be addressed. Based on molecular phylogenetics, we attempt to illustrate the phylogenetic relationships and discuss generic delimitation within Orchidinae. Seven DNA markers (five plastid and two nuclear), a broad sampling of Orchidinae (400 species in 52 genera) and three methods of phylogenetic analysis (maximum likelihood, maximum parsimony and Bayesian inference) were used. RESULTS: Orchidinae s.l. are monophyletic. Satyrium is sister to the rest of Orchidinae s.l. Brachycorythis and Schizochilus are successive sister to Asian-European Orchidinae s.s. Sirindhornia and Shizhenia are successive sister to clade formed by Tsaiorchis-Hemipilia Ponerorchis alliance. Stenoglottis is sister to the Habenaria-Herminium Peristylus alliance. Habenaria, currently the largest genus in Orchidinae, is polyphyletic and split into two distant clades: one Asian-Australian and the other African-American-Asian. Diplomeris is sister to Herminium s.l. plus Asian Australian Habenaria. CONCLUSIONS: We propose to recognize five genera in the Ponerorchis alliance: Hemipilia, Ponerorchis s.l., Sirindhornia, Shizhenia and Tsaiorchis. Splitting Habenaria into two genera based on morphological characters and geographical distribution may be the least disruptive approach, and it is reasonable to keep Satyrium in Orchidinae.

AB - BACKGROUND: Cordyceps militaris is an insect pathogenic fungus that is prized for its use in traditional medicine. This and other entomopathogenic fungi are understudied sources for the discovery of new bioactive molecules. In this study, PacBio SMRT long read sequencing technology was used to sequence the genome of C. militaris with a focus on the genetic potential for secondary metabolite production in the genome assembly of this fungus. RESULTS: This is first chromosome level assembly of a species in the Cordyceps genera. In this seven chromosome assembly of 33.6 Mba there were 9371 genes identified. Cordyceps militaris was determined to have the MAT 1-1-1 and MAT 1-1-2 mating type genes. Secondary metabolite analysis revealed the potential for at least 36 distinct metabolites from a variety of classes. Three of these gene clusters had homology with clusters producing desmethylbassianin, equisetin and emericellamide that had been studied in other fungi. CONCLUSION: Our assembly and analysis has revealed that C. militaris has a wealth of gene clusters for secondary metabolite production distributed among seven chromosomes. The identification of these gene clusters will facilitate the future study and identification of the secondary metabolites produced by this entomopathogenic fungus. PMID- 29178837 TI - VISPA2: a scalable pipeline for high-throughput identification and annotation of vector integration sites. AB - BACKGROUND: Bioinformatics tools designed to identify lentiviral or retroviral vector insertion sites in the genome of host cells are used to address the safety and long-term efficacy of hematopoietic stem cell gene therapy applications and to study the clonal dynamics of hematopoietic reconstitution. The increasing number of gene therapy clinical trials combined with the increasing amount of Next Generation Sequencing data, aimed at identifying integration sites, require both highly accurate and efficient computational software able to correctly process "big data" in a reasonable computational time. RESULTS: Here we present VISPA2 (Vector Integration Site Parallel Analysis, version 2), the latest optimized computational pipeline for integration site identification and analysis with the following features: (1) the sequence analysis for the integration site processing is fully compliant with paired-end reads and includes a sequence quality filter before and after the alignment on the target genome; (2) an heuristic algorithm to reduce false positive integration sites at nucleotide level to reduce the impact of Polymerase Chain Reaction or trimming/alignment artifacts; (3) a classification and annotation module for integration sites; (4) a user friendly web interface as researcher front-end to perform integration site analyses without computational skills; (5) the time speedup of all steps through parallelization (Hadoop free). CONCLUSIONS: We tested VISPA2 performances using simulated and real datasets of lentiviral vector integration sites, previously obtained from patients enrolled in a hematopoietic stem cell gene therapy clinical trial and compared the results with other preexisting tools for integration site analysis. On the computational side, VISPA2 showed a > 6-fold speedup and improved precision and recall metrics (1 and 0.97 respectively) compared to previously developed computational pipelines. These performances indicate that VISPA2 is a fast, reliable and user-friendly tool for integration site analysis, which allows gene therapy integration data to be handled in a cost and time effective fashion. Moreover, the web access of VISPA2 ( http://openserver.itb.cnr.it/vispa/ ) ensures accessibility and ease of usage to researches of a complex analytical tool. We released the source code of VISPA2 in a public repository ( https://bitbucket.org/andreacalabria/vispa2 ). PMID- 29178838 TI - Hepatitis C virus eradication improves immediate and delayed episodic memory in patients treated with interferon and ribavirin. AB - BACKGROUND: Chronic hepatitis C virus (HCV) infection is associated with impairment of cognitive function and mood disorders. Our aim was to evaluate the impact of sustained virological response (SVR) on cognitive function and mood disorders. METHOD: A prospective exploratory one arm study was conducted. Adult clinically compensated HVC patients were consecutively recruited before treatment with interferon and ribavirin for 24 to 48 weeks, according to HCV genotype. Clinical, neurocognitive and mood assessments using the PRIME-MD and BDI instruments were performed at baseline, right after half of the expected treatment has been reached and 6 months after the end of antiviral treatment. Exclusion criteria were the use of illicit psychotropic substances, mental confusion, hepatic encephalopathy, hepatocellular carcinoma, severe anemia, untreated hypothyroidism, Addison syndrome and major depression before treatment. RESULTS: Thirty six patients were enrolled and 21 completed HCV treatment (n = 16 with SVR and n = 5 without). Regardless of the viral clearance at the end of treatment, there was a significant improvement in the immediate verbal episodic memory (p = 0.010), delayed verbal episodic memory (p = 0.007), selective attention (p < 0.001) and phonemic fluency (p = 0.043). Patients with SVR displayed significant improvement in immediate (p = 0.045) and delayed verbal episodic memory (p = 0.040) compared to baseline. The baseline frequency of depression was 9.5%, which rose to 52.4% during treatment, and returned to 9.5% 6 months after the end of treatment, without significant difference between patients with and without SVR. Depressive symptoms were observed in 19.1% before treatment, 62% during (p = 0.016) and 28.6% 6 months after the end of treatment (p = 0.719). CONCLUSIONS: Eradication of HCV infection improved cognitive performance but did not affect the frequency of depressive symptoms at least in the short range. PMID- 29178839 TI - Effects of IFN-gamma coding plasmid supplementation in the immune response and protection elicited by Trypanosoma cruzi attenuated parasites. AB - BACKGROUND: Previous studies showed that a naturally attenuated strain from Trypanosoma cruzi triggers an immune response mainly related to a Th2-type profile. Albeit this, a strong protection against virulent challenge was obtained after priming mice with this attenuated strain. However, this protection is not enough to completely clear parasites from the host. In T. cruzi infection, early Interferon-gamma (IFN-gamma) is critical to lead type 1 responses able to control intracellular parasites. Therefore we evaluated whether the co-administration of a plasmid encoding murine IFN-gamma could modify the immune response induced by infection with attenuated parasites and improve protection against further infections. METHODS: C57BL/6J mice were infected intraperitoneally with three doses of live attenuated parasites in combination with plasmid pVXVR-mIFN-gamma. Before each infection dose, sera samples were collected for parasite specific antibodies determination and cytokine quantification. To evaluate the recall response to T. cruzi, mice were challenged with virulent parasites 30 days after the last dose and parasite load in peripheral blood and heart was evaluated. RESULTS: As determined by ELISA, significantly increase in T. cruzi specific antibodies response was detected in the group in which pVXVR-mIFN-gamma was incorporated, with a higher predominance of IgG2a subtype in comparison to the group of mice only inoculated with attenuated parasites. At our limit of detection, serum levels of IFN-gamma were not detected, however a slight decrease in IL-10 concentrations was observed in groups in which pVXVR-mIFN-gamma was supplemented. To analyze if the administration of pVXVR-mIFN-gamma has any beneficial effect in protection against subsequent infections, all experimental groups were submitted to a lethal challenge with virulent bloodstream trypomastigotes. Similar levels of challenge parasites were detected in peripheral blood and heart of mice primed with attenuated parasites alone or combined with plasmid DNA. Expansion of IgG antibodies was not significant in TCC+ pVXVR-mIFN-gamma; however, the overall tendency to sustain a Th2 profile was maintained. CONCLUSIONS: Overall, these results suggest that administration of plasmid pVXVR-mIFN-gamma could have beneficial effects on host specific antibody production in response to T. cruzi attenuated infection; however, this outcome is not reflected in an improved protection against further virulent infections. PMID- 29178840 TI - Prevalence of oncogenic human papillomavirus genotypes in patients diagnosed with anogenital malignancies in Botswana. AB - BACKGROUND: Human papillomavirus (HPV) associated malignancies are the leading cause of cancer death in Botswana. We sought to determine causative HPV types in patients with anogenital malignancies in Botswana to inform vaccine strategy. METHODS: We used formalin-fixed and paraffin-embedded (FFPE) tissue blocks from patients diagnosed with anal, penile and vulvar squamous cell carcinomas between the years, 2014 and 2016. Presence of HPV 16, 18, or other high-risk (HR) types was detected using Abbott m2000 real-time PCR platform. Tissues with other high risk types were subsequently analysed using a multiplex qPCR assay that includes 15 validated fluorophore probes. RESULTS: A total of 126 tissue specimens, comprising of 21 anal (9 males, 12 females), 31 penile and 74 vulvar were studied. Ninety-three (73.8%) patients had their HIV status documented in the records while the rest did not. Eighty-three (83) out of 93 were HIV positive, a prevalence of 89.4% (95% CI: 81-94). HPV was detected in 68/126 (54%) tissues, of which 69% (95% CI: 54-79) had HPV 16 only, 28% (95% CI: 19-40) had other hr.-HPV types and 2.9% (95% CI, 3.5-10.1) were co-infected with HPV 16 and other hr. types. Other high-risk types detected included HPV 26, 31, 33, 35, 39, 45, 51, 52, 66 and 68. HPV 18 was not detected. Multiple-type HPV infection was detected in 44 of 47 (93.6%) HIV positive participants co-infected with HPV. In HIV negative individuals, only HPV 16 was detected. CONCLUSION: In our study, anogenital carcinomas were associated with HPV 16 and other hr.-HPV types besides HPV 16 and 18. HIV co-infected patients had multiple hr.-HPV types detected whereas in HIV-negative patients only HPV 16 was detected. Our study suggests that multivalent vaccines may be more suitable in this setting, especially for HIV-infected individuals. PMID- 29178841 TI - Multiresistant ST59-SCCmec IV-t437 clone with strong biofilm-forming capacity was identified predominantly in MRSA isolated from Chinese children. AB - BACKGROUND: This study aimed to investigate the clinical and molecular epidemiology and biofilm formation of Staphylococcus aureus (SA) isolated from pediatricians in China. METHODS: SA strains were isolated from Beijing Children's hospital from February 2016 to January 2017. Isolates were typed by multilocus sequence typing (MLST), spa and SCCmec typing (for Methicillin-resistant SA [MRSA] only). Antimicrobial susceptibility testing was performed by agar dilution method except sulphamethoxazole/trimethoprim (E-test method). Biofilm formation and biofilm associated genes were detected. RESULTS: Totally 104 children (41 females and 63 males; median age, 5.2 months) were enrolled in this study, in which 60 patients suffered from MRSA infection. Among the 104 cases, 54.8% were categorized as community associated SA (CA-SA) infections. The children under 3 years were more likely to occur CA-SA infections compared with older ones (P = 0.0131). ST59-SCCmec IV-t437 (61.7%) was the most prevalent genotype of MRSA, and ST22-t309 (18.2%), ST5-t002 (9.1%), ST6-t701 (9.1%), ST188-t189 (9.1%) were the top four genotypes of methicillin-sensitive SA (MSSA). All the present isolates were susceptible to linezolid, vancomycin, trimethoprim-sulfamethoxazole, mupirocin, tigecyclin, fusidic acid. No erythromycin-susceptible isolate was determined, and only a few isolates (3.8%) were identified as susceptible to penicillin. Multi-drug resistant isolates were reponsible for 83.8% of the ST59 SCCmec IV-t437 isolates. The isolates with strong biofilm formation were found in 85% of MRSA and 53.2% of MSSA, and in 88.7% of ST59-SCCmec IV-t437 isolates. Biofilm formation ability varied not only between MRSA and MSSA (P = 0.0053), but also greatly among different genotypes (P < 0.0001). The prevalence of the biofilm associated genes among ST59-SCCmec IV-t437 clone was: icaA (100.0%), icaD (97.3%), fnbpA (100.0%), fnbpB (0), clfA (100%), clfB (100%), cna (2.7%), bbp (0), ebpS (88.5%), sdrC (78.4%), sdrD (5.4%), and sdrE (94.5%). CONCLUSIONS: These results indicated strong homology of the MRSA stains isolated from Chinese children, which was caused by spread of multiresistant ST59-SCCmec IV-t437 clone with strong biofilm formation ability. The MSSA strains, in contrast, were very heterogeneity, half of which could produce biofilm strongly. PMID- 29178842 TI - A non-interventional, observational study of a fixed combination of pepsin and amino acid hydrochloride in patients with functional dyspepsia. AB - BACKGROUND: Functional dyspepsia (FD) is a gastrointestinal disorder characterized by recurrent and diverse symptoms and pathophysiology that remains unexplained following routine clinical investigation. Enzynorm(r)f is a pharmaceutical preparation comprising fixed amounts of pepsin of biological origin and organically bound acid in the form of amino acid hydrochloride. It is traditionally used as a mild agent to support gastric function and to stimulate the stomach's proteolytic activities in FD. METHODS: In a non-interventional, observational, post-marketing surveillance study, patients with an established diagnosis of FD were treated with a fixed combination of pepsin and amino acid hydrochloride taken as tablets three times daily for 6 weeks. The primary objective of this study was to assess the change in symptoms using the validated Gastrointestinal Symptom Score (GIS(c)). Secondary objectives included patients' assessment of their gastrointestinal symptoms as well as treatment safety and tolerability. RESULTS: A total of 97 patients (mean age 58.4 +/- 13.9 years; 63.2% females) were included in the study, with 72 data having GIS(c) score data at baseline and at 6 weeks, and 34 also at 3 weeks. The overall GIS(c) sum score decreased by 4.1 (p < 0.0001) from 11.6 (+/-4.8) at baseline to 7.4 (+/- 4.6) reflecting an improvement of clinical symptomatology after 6 weeks of treatment. In a subgroup of 70 patients who had FD meeting the Rome III criteria a GIS(c) score reduction of >=50% was observed after 3 weeks treatment in 24% and in 30.8% after 6 weeks. Adverse events were mostly gastrointestinal in nature and consistent with the underlying disease; no unexpected adverse reactions were reported. Twenty-seven patients discontinued the study, mostly because of gastrointestinal symptoms. CONCLUSION: The results of this study support the efficacy of a fixed combination of pepsin and amino acid hydrochloride for the treatment of patients with FD and also suggest good to moderate treatment tolerability. These findings should be further explored in a randomised, placebo controlled clinical trial. CLINICAL TRIAL REGISTRATION: This study has been retrospectively registered in the ClinicalTrials.gov registry, trial identifier NCT03076411 . PMID- 29178843 TI - A qualitative evidence synthesis to explore healthcare professionals' experience of prescribing opioids to adults with chronic non-malignant pain. AB - BACKGROUND: Despite recent guidelines suggesting that patients with chronic non malignant pain might not benefit, there has been a significant rise in opioid prescription for chronic non-malignant pain. This topic is important because an increasing number of HCPs are prescribing opioids despite very limited evidence for long-term opioid therapy for chronic non-malignant pain outside of end-of life care. To better understand the challenges of providing effective treatment, we conducted the first qualitative evidence synthesis to explore healthcare professionals' experience of treating people with chronic non-malignant pain. We report findings that explore healthcare professionals' experience of prescribing opioids to this group of patients. METHODS: We searched five electronic bibliographic databases (Medline, Embase, CINAHL, PsychINFO, AMED) from inception to November 2015 and screened titles, abstracts and full texts of potential studies. We included studies in English that explored healthcare professionals' experience of treating adults with chronic non-malignant pain. Two reviewers quality appraised each paper. We used the methods of meta-ethnography developed and refined for large reviews, and the GRADE-CERQual framework to rate confidence in review findings. RESULTS: We screened 954 abstracts and 184 full texts, and included 77 studies in the full review. 17 of these 77 studies included concepts that explored the experience of prescribing opioids. We abstracted these concepts into 6 overarching themes: (1) Should I, shouldn't I? (2) Pain is Pain; (3) Walking a fine line; (4) Social guardianship; (5) Moral boundary work; (6) Regulations and guidelines. We used the GRADE-CERQual framework to evaluate confidence in findings. A new overarching concept of 'ambiguity' explains the balancing required around the factors taken into account when prescribing opioids. Managing this ambiguity is challenging and these findings can inform healthcare professionals dealing with these decisions. CONCLUSIONS: This conceptual model demonstrates the complexity of making a decision to prescribe opioids to someone with chronic non-malignant pain. Although opioid prescription is underpinned by the therapeutic aim of alleviating pain, this aim may be misplaced. This has implications for education in light of the new regulations for opioid prescription. Findings also demonstrate that the decision is influenced by intra- and interpersonal factors and broader external concerns. PMID- 29178844 TI - BoolFilter: an R package for estimation and identification of partially-observed Boolean dynamical systems. AB - BACKGROUND: Gene regulatory networks govern the function of key cellular processes, such as control of the cell cycle, response to stress, DNA repair mechanisms, and more. Boolean networks have been used successfully in modeling gene regulatory networks. In the Boolean network model, the transcriptional state of each gene is represented by 0 (inactive) or 1 (active), and the relationship among genes is represented by logical gates updated at discrete time points. However, the Boolean gene states are never observed directly, but only indirectly and incompletely through noisy measurements based on expression technologies such as cDNA microarrays, RNA-Seq, and cell imaging-based assays. The Partially Observed Boolean Dynamical System (POBDS) signal model is distinct from other deterministic and stochastic Boolean network models in removing the requirement of a directly observable Boolean state vector and allowing uncertainty in the measurement process, addressing the scenario encountered in practice in transcriptomic analysis. RESULTS: BoolFilter is an R package that implements the POBDS model and associated algorithms for state and parameter estimation. It allows the user to estimate the Boolean states, network topology, and measurement parameters from time series of transcriptomic data using exact and approximated (particle) filters, as well as simulate the transcriptomic data for a given Boolean network model. Some of its infrastructure, such as the network interface, is the same as in the previously published R package for Boolean Networks BoolNet, which enhances compatibility and user accessibility to the new package. CONCLUSIONS: We introduce the R package BoolFilter for Partially-Observed Boolean Dynamical Systems (POBDS). The BoolFilter package provides a useful toolbox for the bioinformatics community, with state-of-the-art algorithms for simulation of time series transcriptomic data as well as the inverse process of system identification from data obtained with various expression technologies such as cDNA microarrays, RNA-Seq, and cell imaging-based assays. PMID- 29178845 TI - Classification of a new phytoplasmas subgroup 16SrII-W associated with Crotalaria witches' broom diseases in Oman based on multigene sequence analysis. AB - BACKGROUND: Crotalaria aegyptiaca, a low shrub is commonly observed in the sandy soils of wadis desert and is found throughout all regions in Oman. A survey for phytoplasma diseases was conducted. During a survey in a wild area in the northern regions of Oman in 2015, typical symptoms of phytoplasma infection were observed on C. aegyptiaca plants. The infected plants showed an excessive proliferation of their shoots and small leaves. RESULTS: The presence of phytoplasma in the phloem tissue of symptomatic C. aegyptiaca leaf samples was confirmed by using Transmission Electron Microscopy (TEM). In addition the extracted DNA from symptomatic C. aegyptiaca leaf samples and Orosius sp. leafhoppers were tested by PCR using phytoplasma specific primers for the 16S rDNA, secA, tuf and imp, and SAP11 genes. The PCR amplifications from all samples yielded the expected products, but not from asymptomatic plant samples. Sequence similarity and phylogenetic tree analyses of four genes (16S rDNA, secA, tuf and imp) showed that Crotalaria witches' broom phytoplasmas from Oman is placed with the clade of Peanut WB (16SrII) close to Fava bean phyllody (16SrII-C), Cotton phyllody and phytoplasmas (16SrII-F), and Candidatus Phytoplasma aurantifolia' (16SrII-B). However, the Crotalaria's phytoplasma was in a separate sub-clade from all the other phytoplasmas belonging to Peanut WB group. The combination of specific primers for the SAP11 gene of 16SrII-A, -B, and -D subgroup pytoplasmas were tested against Crotalaria witches' broom phytoplasmas and no PCR product was amplified, which suggests that the SAP11 of Crotalaria phytoplasma is different from the SAP11 of the other phytoplasmas. CONCLUSION: We propose to assign the Crotalaria witches' broom from Oman in a new lineage 16SrII-W subgroup depending on the sequences analysis of 16S rRNA, secA, imp, tuf, and SAP11 genes. To our knowledge, this is the first report of phytoplasmas of the 16SrII group infecting C. aegyptiaca worldwide. PMID- 29178846 TI - An optimized protocol for the preparation of oxygen-evolving thylakoid membranes from Cyclotella meneghiniana provides a tool for the investigation of diatom plastidic electron transport. AB - BACKGROUND: The preparation of functional thylakoid membranes from diatoms with a silica cell wall is still a largely unsolved challenge. Therefore, an optimized protocol for the isolation of oxygen evolving thylakoid membranes of the centric diatom Cyclotella meneghiniana has been developed. The buffer used for the disruption of the cells was supplemented with polyethylene glycol based on its stabilizing effect on plastidic membranes. Disruption of the silica cell walls was performed in a French Pressure cell and subsequent linear sorbitol density gradient centrifugation was used to isolate the thylakoid membrane fraction. RESULTS: Spectroscopic characterization of the thylakoids by absorption and 77 K fluorescence spectroscopy showed that the photosynthetic pigment protein complexes in the isolated thylakoid membranes were intact. This was supported by oxygen evolution measurements which demonstrated high electron transport rates in the presence of the artificial electron acceptor DCQB. High photosynthetic activity of photosystem II was corroborated by the results of fast fluorescence induction measurements. In addition to PSII and linear electron transport, indications for a chlororespiratory electron transport were observed in the isolated thylakoid membranes. Photosynthetic electron transport also resulted in the establishment of a proton gradient as evidenced by the quenching of 9-amino acridine fluorescence. Because of their ability to build-up a light-driven proton gradient, de-epoxidation of diadinoxanthin to diatoxanthin and diatoxanthin dependent non-photochemical quenching of chlorophyll fluorescence could be observed for the first time in isolated thylakoid membranes of diatoms. However, the ?pH, diadinoxanthin de-epoxidation and diatoxanthin-dependent NPQ were weak compared to intact diatom cells or isolated thylakoids of higher plants. CONCLUSIONS: The present protocol resulted in thylakoids with a high electron transport capacity. These thylakoids can thus be used for experiments addressing various aspects of the photosynthetic electron transport by, e.g., employing artificial electron donors and acceptors which do not penetrate the diatom cell wall. In addition, the present isolation protocol yields diatom thylakoids with the potential for xanthophyll cycle and non-photochemical quenching measurements. However, the preparation has to be further refined before these important topics can be addressed systematically. PMID- 29178848 TI - Anti-fibrotic, anti-VEGF or radiotherapy treatments as adjuvants for pterygium excision: a systematic review and network meta-analysis. AB - BACKGROUND: Anti-fibrotic, anti-VEGF (vascular endothelial growth factor) medications, or radiotherapy, as adjuvant for pterygium surgical procedure, has been suggested for reducing recurrence, but difficulties may be experienced in deciding which treatment to use. The purpose of this study was to compare the efficacies of these different adjuvants for preventing recurrence following pterygium surgery. METHODS: We conducted a systematic review to identify randomized controlled trials of patients with primary or recurrent pterygium who received anti-fibrotic, anti-VEGF medication, or radiotherapy as adjuvants in combination with surgical procedure. The surgical procedure contained bare sclera technique or petrygium excision combination with tissue grafting. The primary outcome of this study was recurrence. Direct-comparison and Bayesian network meta analyses were performed to assess direct and indirect evidence of efficacy. RESULTS: We obtained data from 34 randomized controlled trials, representing a total of 2483 patients. Adjuvants included bevacizumab, 5-FU (5-fluorouracil), MMC (mitomycin C), and beta-RT (beta-radiotherapy). Compared with placebo, we found distinguishable improvement in recurrence with bevacizumab (odds ratio [OR] 0.38, 95% confidence interval [CI] 0.18-0.80), MMC (0.12, 95% CI 0.06-0.21), and beta-RT (0.17, 95% CI 0.04-0.69), but not with 5-FU (0.41, 95% CI 0.12-1.39). MMC significantly reduced recurrence when compared to bevacizumab (0.31, 95% CI 0.13 0.77) and 5-FU (0.28, 95% CI 0.08-0.99). The probability of having the most recurrences after excision was lowest for MMC, followed by bevacizumab and beta RT. Similar results were found in subgroup analyses, including for primary pterygium, and the patients receiving bare sclera technique or conjunctival autograft. CONCLUSIONS: Adjuvants such as MMC, bevacizumab, and beta-RT could effectively prevent recurrence following pterygium excision. However, their efficacy and acceptability require further clarification in future randomized controlled trials. PMID- 29178849 TI - Goldmann applanation tonometry error relative to true intracameral intraocular pressure in vitro and in vivo. AB - BACKGROUND: Goldmann applanation tonometry (GAT) error relative to intracameral intraocular pressure (IOP) has not been examined comparatively in both human cadaver eyes and in live human eyes. Futhermore, correlations to biomechanical corneal properties and positional changes have not been examined directly to intracameral IOP and GAT IOP. METHODS: Intracameral IOP was measured via pressure transducer on fifty-eight (58) eyes undergoing cataract surgery and the IOP was modulated manometrically on each patient alternately to 10, 20, and 40 mmHg. IOP was measured using a Perkins tonometer in the supine position on 58 eyes and upright on a subset of 8 eyes. Twenty one (21) fresh human cadaver globes were Intracamerally IOP adjusted and measured via pressure transducer. Intracameral IOP ranged between 5 and 60 mmHg. IOP was measured in the upright position with a Goldmann Applanation Tonometer (GAT) and supine position with a Perkins tonometer. Central corneal thickness (CCT) was also measured. RESULTS: The Goldmann-type tonometer error measured on live human eyes was 5.2 +/-1.6 mmHg lower than intracameral IOP in the upright position and 7.9 +/- 2.3 mmHg lower in the supine position (p < .05). CCT also indicated a sloped correlation to error (correlation coeff. = 0.18). Cadaver eye IOP measurements were 3.1+/-2.5 mmHg lower than intracameral IOP in the upright position and 5.4+/- 3.1 mmHg in the supine position (p < .05). CONCLUSION: Goldmann IOP measures significantly lower than true intracameral IOP by approximately 3 mmHg in vitro and 5 mmHg in vivo. The Goldmann IOP error is increased an additional 2.8 mmHg lower in the supine position. CCT appears to significantly affect the error by up to 4 mmHg over the sample size. PMID- 29178850 TI - Factors associated with the occurrence of a fall in subjects with primary open angle glaucoma. AB - BACKGROUND: The aim of the study is to investigate risk factors for future falls in subject with primary open angle glaucoma (POAG). METHODS: All participants answered the following question at their baseline ophthalmic examination: Have you had any falls in the last year? (Yes/No). All study participants answered the same question every 12 months for 3 years. The means of total deviation values in the whole, superior peripheral, superior central, inferior central, and inferior peripheral visual fields (VF) were calculated. The relationship between these mean VF measurements, and various clinical factors against patients' future falls was analyzed using multiple linear regression. RESULTS: Two-hundred ninety four POAG patients answered the baseline and follow-up fall questionnaires over a period of three years. Among 294 subjects, 69 patients experienced a fall during the three-year follow-up. History of falls at baseline (coefficient = 1.22), history of fear of falling at baseline (0.53), best corrected visual acuity in the worse eye (7.37), prevalence of diabetes mellitus (0.60), prevalence of systemic hypertension (0.53) were selected in the optimal model. CONCLUSIONS: Visual acuity in the worse eye, history of falls, fear of falling, diabetes mellitus, and systemic hypertension are risk factors for falling in subjects with POAG. PMID- 29178851 TI - Bacterial profile of ocular infections: a systematic review. AB - BACKGROUND: Bacteria are the major contributor of ocular infections worldwide. Ocular infections, if left untreated, can damage the structures of the eye with possible blindness and visual impairments. This work was aimed to review the bacterial profile of ocular infections. METHODS: Literature search was made in different electronic databases; the review was systematically made to get concrete findings. RESULTS: As far as this review, Staphylococcus aureus, Coagulase negative Staphylococci, Streptococcus pneumoniae and Pseudomonas aeruginosa are the leading isolates in ocular infections. Frequent pathogens of the respective clinical diagnose include Staphylococci, Streptococcus pyogenes and Pseudomonas aeruginosa in blepharitis; Staphylococci, Streptococus pneumoniae, Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli in Conjunctivitis; Staphylococci, P. aeruginosa and E. coli in dacryocystitis; Coagulase negative Staphylococci, Pseudomonas aeruginosa and Staphylococcus aureus in keratitis; Streptococcus viridians, Streptococcus pneumoniae and Coagulase negative Staphylococci in endophthalmitis diagnoses. Endogenous endophthalmitis is associated with Klebsiella pneumoniae whereas Coagulase negative Staphylococci and Bacillus spp. are common causes of post-operative and post-traumatic endophthalmitis. However, the predominant pathogens may not be exactly same in all areas of the world, in the United States for instance, Staphylococcus aureus, Streptococcus pneumoniae and Haemophilus influenzae are the major causes of conjunctivitis. CONCLUSION: Gram positive bacteria are the major contributor of bacterial ocular infections. The distribution and proportion of bacterial isolates among clinical diagnoses varied but without exclusive anatomical restriction. To mitigate the burden of bacterial ocular infections, physicians should regard on risk reduction and comply with etiologic approach of diagnosis. PMID- 29178852 TI - Couples HIV counselling and couple relationships in India, Georgia and the Dominican Republic. AB - BACKGROUND: Couples HIV counseling and testing is essential for combination HIV prevention, but its uptake remains very low. We aimed to evaluate factors associated with couples HIV counseling uptake in India, Georgia and the Dominican Republic, as part of the ANRS 12127 Prenahtest intervention trial. METHODS: Pregnant women >=15 years, attending their first antenatal care (ANC) session between March and September 2009, self-reporting a stable partner, and having received couple-oriented post-test HIV counseling (trial intervention) were included. Individuals and couple characteristics associated with the acceptability of couples HIV counseling were assessed using multivariable logistic regression for each study site. RESULTS: Among 711 women included (232, 240 and 239 in the Dominican Republic, Georgia and India, respectively), the uptake of couples HIV counseling was 9.1% in the Dominican Republic, 13.8% in Georgia and 36.8% in India. The uptake of couples HIV counseling was associated with women having been accompanied by their partner to ANC, and never having used a condom with their partner in the Dominican Republic; with women having been accompanied by their partner to ANC in India; with women having a higher educational level than their partner and having ever discussed HIV with their partner in Georgia. CONCLUSION: Couple HIV counseling uptake was overall low. Strategies adapted to local socio-cultural contexts, aiming at improving women's education level, or tackling gender norms to facilitate the presence of men in reproductive health services, should be considered.

PMID- 29178853 TI - Pleural plaques in lung cancer screening by low-dose computed tomography: prevalence, association with lung cancer and mortality. AB - BACKGROUND: To report the prevalence of pleural plaques in a lung cancer screening trial by low-dose computed tomography (LDCT) and to test the association with incidence of lung cancer and mortality. METHODS: The LDCT of 2303 screenees were retrospectively reviewed with the specific aim of describing the prevalence and features of pleural plaques. Self-administered questionnaire was used to assess asbestos exposure. Frequency of lung cancer, lung cancer mortality, and overall mortality were detailed according to presence of pleural findings. Statistical analyses included comparison of mean or median, contingency tables, and Cox model for calculation of hazard ratio (HR) and its 95% confidence interval (CI). RESULTS: Among male screenees, 31/1570 (2%) showed pleural abnormalities, 128/1570 (8.2%) disclosed asbestos exposure, 23/31 (74.2%) subjects with pleural plaques consistently denied exposure to asbestos. There was a trend for higher frequency of lung cancer among subjects with pleural plaques (9.7% vs 4.2%). Lung cancer in subjects with pleural plaques was always diagnosed in advanced stage. Subjects with pleural plaques showed HR 5.48 (95% CI 1.61 18.70) for mortality from lung cancer. CONCLUSIONS: Pleural plaques are a risk factor for lung cancer mortality that can be detected in lung cancer screening by LDCT, also in subjects that are not aware of asbestos exposure.

PMID- 29178847 TI - HIV serostatus knowledge and serostatus disclosure with the most recent anal intercourse partner in a European MSM sample recruited in 13 cities: results from the Sialon-II study. AB - BACKGROUND: Knowledge of HIV status can be important in reducing the risk of HIV exposure. In a European sample of men-who-have-sex-with-men (MSM), we aimed to identify factors associated with HIV serostatus disclosure to the most recent anal intercourse (AI) partner. We also aimed to describe the impact of HIV serostatus disclosure on HIV exposure risks. METHODS: During 2013 and 2014, 4901 participants were recruited for the bio-behavioural Sialon-II study in 13 European cities. Behavioural data were collected with a self-administered paper questionnaire. Biological specimens were tested for HIV antibodies. Factors associated with HIV serostatus disclosure with the most recent AI partner were examined using bivariate and multilevel multivariate logistic regression analysis. We also describe the role of serostatus disclosure for HIV exposure of the most recent AI partner. RESULTS: Thirty-five percent (n = 1450) of the study participants reported mutual serostatus disclosure with their most recent AI partner or disclosed having HIV to their partner. Most of these disclosures occurred between steady partners (74%, n = 1077). In addition to the type of partner and HIV diagnosis status, other factors positively associated with HIV serostatus disclosure in the multilevel multivariate logistic regression model were recent testing, no condom use, and outness regarding sexual orientation. Disclosure rates were lowest in three south-eastern European cities. Following condom use (51%, n = 2099), HIV serostatus disclosure (20%, n = 807) was the second most common prevention approach with the most recent AI partner, usually resulting in serosorting. A potential HIV exposure risk for the partner was reported by 26% (111/432) of HIV antibody positive study participants. In 18% (20/111) of exposure episodes, an incorrect HIV serostatus was unknowingly communicated. Partner exposures were equally distributed between steady and non steady partners. CONCLUSIONS: The probability of HIV exposure through condomless AI is substantially lower after serostatus disclosure compared to non-disclosure. Incorrect knowledge of one's HIV status contributes to a large proportion of HIV exposures amongst European MSM. Maintaining or improving condom use for anal intercourse with non-steady partners, frequent testing to update HIV serostatus awareness, and increased serostatus disclosure particularly between steady partners are confirmed as key aspects for reducing HIV exposures amongst European MSM. PMID- 29178854 TI - Subtrochanteric shortening osteotomy during cementless total hip arthroplasty in young patients with severe developmental dysplasia of the hip. AB - BACKGROUND: This retrospective study was designed to determine complications, functional and radiographic results of transverse subtrochanteric osteotomy during cementless, modular total hip arthroplasty (THA) in a series of active patients younger than 45 years with Crowe Type-III or IV developmental dysplasia of the hip (DDH). METHODS: We followed 49 patients (56 hips) with DDH who were treated with cementless THA, where the acetabular cup was positioned in the anatomic hip center and where a simultaneous transverse femoral osteotomy was performed. Complication rate evaluation and clinical outcomes were measured by validated clinical scores and radiographic evaluation were performed at a mean follow up of 10 years (range, 4.8-14.3 years). RESULTS: The mean limb-length discrepancy was reduced from 4.2 cm to 1.1 cm (P < 0.01). The mean Harris hip score (HSS) significantly improved from 40.6 points to 87.4 points (P < 0.01). Similarly, severity of low back pain, modified MAP, HOOS, and SF-12 also showed significant improvement (P < 0.01). There were 3 cases of postoperative dislocation, 3 cases of transient nerve palsy, 2 cases of nonunion, and 4 cases of intraoperative fracture. At 10 years follow-up, the estimated survival rate with any component revision as end points was 92%. CONCLUSION: The cementless THA combined with transverse subtrochanteric osteotomy is a reliable technique with restoration of a more normal limb, satisfactory clinical outcomes, and mid-term survival of components. PMID- 29178855 TI - Prices of over-the-counter drugs used by 15-year-old adolescents in Germany and their association with socioeconomic background. AB - BACKGROUND: In Germany, over-the-counter (OTC) drugs are normally reimbursed up to the age of 12 years only. The aim of this study was to analyse prices of over the-counter drugs used by adolescents in Germany and their association with socioeconomic factors. METHODS: Based on the German GINIplus and LISAplus birth cohorts, data on drug utilization among 15-year-old adolescents (n = 4677) were collected using a self-administered questionnaire. The reported drugs were subdivided into prescription drugs and OTC drugs. The drugs' prices were tracked by the pharmaceutical identification numbers. RESULTS: Overall, 1499 OTC drugs with clearly identifiable prices were eligible for analysis. Their mean price was ?9.75 (95% confidence interval: ?9.27-10.22). About 75% of the OTC drugs cost less than ?10. Higher mean prices were associated with residing in Munich (?10.74; 95% confidence interval: ?9.97-11.52) and with higher paternal education (e.g. highest education level: ?10.17; 95% confidence interval: ?9.47-10.86). Adolescents residing in Munich (in comparison with the less wealthy region of Wesel) and adolescents with higher educated fathers were also significantly more likely to use OTC drugs costing >= ?10 or >= ?25, respectively. CONCLUSIONS: The price of ?10 for non-reimbursable OTC drugs may represent a (psychological) threshold. Higher prices could discourage especially adolescents from a lower socioeconomic background from taking medically advisable but non-reimbursable OTC drugs. PMID- 29178856 TI - Influence of age on results following surgery for displaced acetabular fractures in the elderly. AB - BACKGROUND: Elderly patients have more special medical needs when compared with young ones; thus, the results of open reduction and internal fixation (ORIF) for acetabular fractures should be stratified by age in these patients. This study seeks to determine whether the age of the patient influences the results of the ORIF for acetabular fractures. METHODS: We performed a retrospective analysis of prospectively collected data on 53 elderly patients with displaced acetabular fractures who underwent ORIF between May 2004 and May 2011. Patients were divided into two groups by age: young-old group (60-74 years) and old-old group (75-90 years). The number of patients in each group was 28 and 25. The reduction quality and clinical function was evaluated using the Matta criteria and modified Postel Merle D'Aubigne Score, respectively. Operative time, bleeding amount, and complications were recorded. RESULTS: Patients in old-old group had significantly lower anatomical reduction rate (p = 0.024), less operative time (p = 0.021), and less bleeding amount (p = 0.016) than those in the young-old group. The reduction quality in the young-old group was strongly associated with clinical function (p < 0.05). However, no difference in clinical function was detected among the different reduction qualities in the old-old group (p > 0.05). Moreover, no significant difference in clinical functions (p = 0.787) and complications (p = 0.728) was detected between the two groups. CONCLUSIONS: Old-old patients may expect comparable clinical functions and complications with young-old patients. The reduction quality in old-old patients may be not significantly associated with clinical function. Different treatment strategies may be applied for acetabular fractures with ORIF in different age groups. PMID- 29178857 TI - Mini - social phobia inventory (mini-SPIN): psychometric properties and population based norms of the German version. AB - BACKGROUND: A short screening for social anxiety disorder is useful in clinical and epidemiological contexts. However, the German version of the short form of the Social Phobia Inventory (mini-SPIN) has not been evaluated yet. Therefore, our aim was to determine reliability, validity and population based norms of the German mini-SPIN. METHODS: The mini-SPIN was evaluated in a clinical (N = 1254) and in a representative community sample (N = 1274). Clinical diagnoses, the Patient Health Questionnaire depression (PHQ-9) and somatization modules (PHQ 15), the Generalized Anxiety Disorder Scale (GAD-7), the Liebowitz Social Anxiety Scale (LSAS), and the Short-Form-12 Health Survey (SF-12) were used in the clinical sample. In the community sample, participants filled out socio demographic and health related questions and short versions of the PHQ (PHQ-2, GAD-2, panic item). Internal consistency, test-retest reliability, sensitivity to change, discriminant validity, and convergent validity were examined. Receiver operating characteristic curve analyses were performed to determine cut-off scores. Population based norms were computed from the community sample. RESULTS: We found internal consistencies between 0.80 and 0.83. Test-retest correlation was Rho = 0.61; sensitivity to change was comparable to the LSAS. Correlations indicated good convergent and discriminant validity of the mini-SPIN. Strict measurement invariance can be assumed regarding age and gender. Receiver operating characteristic curve analysis suggested a cut-off of 6 or higher for a probable diagnosis of SAD. CONCLUSIONS: The German version of the mini-SPIN is a reliable and valid instrument. Its brevity makes it valuable for screening and assessing changes of social anxiety in clinical and epidemiological studies. PMID- 29178858 TI - Measures of excess body weight and anthropometry among adult Albertans: cross sectional results from Alberta's tomorrow project cohort. AB - BACKGROUND: Excess body weight during adulthood has been consistently associated with all-cause mortality, cardiovascular disease, and cancer at multiple sites among other chronic diseases. We describe the prevalence of excess body weight and abdominal obesity reported by participants enrolled in Alberta's Tomorrow Project (ATP). METHODS: ATP is a geographically-based cohort study conducted among adults aged 35-69 years from across the province of Alberta. Participants completed anthropometric measures and health and lifestyle questionnaires at enrolment. Overweight and obese were categorized as a body mass index (BMI) of 25.0-29.9 kg/m2 and >=30 kg/m2, respectively. Abdominal obesity was categorized using cut-offs of waist circumference of >94 cm for men and >80 cm for women and waist-tp-hip ratio cut-offs of >0.90 for men and >0.85 for women. RESULTS: BMI and hip and waist circumference data were obtained from 12,062 men and 18,853 women enrolled between 2001 and 2009. Overall, 76.8% of men and 59.5% of women reported a BMI >=25 kg/m2. The proportions of overweight and obese were significantly higher in older age groups (p < 0.001). In addition, the proportion of participants reporting being overweight and obese was higher among lower education (p < 0.001) and lower income groups (p < 0.001). Overall, approximately two thirds of men and women in ATP cohort reported abdominal obesity. Overweight, obesity and abdominal obesity were all associated with a history of several cardiometabolic chronic conditions including hypertension, heart attack, angina, high cholesterol, stroke and diabetes. CONCLUSION: A large majority of ATP participants were overweight and carried excess abdominal fat. Strategies to improve energy balance among Albertans are encouraged and may have a notable impact on future chronic disease burden. PMID- 29178859 TI - Assessing the impact of the Lebanese National Polio Immunization Campaign using a population-based computational model. AB - BACKGROUND: After the re-introduction of poliovirus to Syria in 2013, Lebanon was considered at high transmission risk due to its proximity to Syria and the high number of Syrian refugees. However, after a large-scale national immunization initiative, Lebanon was able to prevent a potential outbreak of polio among nationals and refugees. In this work, we used a computational individual simulation model to assess the risk of poliovirus threat to Lebanon prior and after the immunization campaign and to quantitatively assess the healthcare impact of the campaign and the required standards that need to be maintained nationally to prevent a future outbreak. METHODS: Acute poliomyelitis surveillance in Lebanon was along with the design and coverage rate of the recent national polio immunization campaign were reviewed from the records of the Lebanese Ministry of Public Health. Lebanese population demographics including Syrian and Palestinian refugees were reviewed to design individual-based models that predicts the consequences of polio spread to Lebanon and evaluate the outcome of immunization campaigns. The model takes into account geographic, demographic and health-related features. RESULTS: Our simulations confirmed the high risk of polio outbreaks in Lebanon within 10 days of case introduction prior to the immunization campaign, and showed that the current immunization campaign significantly reduced the speed of the infection in the event poliomyelitis cases enter the country. A minimum of 90% national immunization coverage was found to be required to prevent exponential propagation of potential transmission. CONCLUSIONS: Both surveillance and immunization efforts should be maintained at high standards in Lebanon and other countries in the area to detect and limit any potential outbreak. The use of computational population simulation models can provide a quantitative approach to assess the impact of immunization campaigns and the burden of infectious diseases even in the context of population migration. PMID- 29178860 TI - A new classification of TKA periprosthetic femur fractures considering the implant type. AB - BACKGROUND: The treatment aims of periprosthetic fractures (PPF) of the distal femur are a gentle stabilization, an early load-bearing capacity and a rapid postoperative mobilization of the affected patients. For the therapy planning of PPF a standardized classification is necessary which leads to a clear and safe therapy recommendation. Despite different established classifications, there is none that includes the types of prosthesis used in the assessment. For this purpose, the objective of this work is to create a new more extensive fracture and implant-related classification of periprosthetic fractures of the distal femur based on available classifications which allows distinct therapeutic recommendations. METHODS: In a retrospective analysis all patients who were treated in the University Hospital Leipzig from 2010 to 2016 due to a distal femur fracture with total knee arthroplasty (TKA) were established. To create an implant-associated classification the cases were discussed in a panel of experienced orthopaedists and well-practiced traumatologists with a great knowledge in the field of endoprosthetics and fracture care. In this context, two experienced surgeons classified 55 consecutive fractures according to Su et al., Lewis and Rorabeck and by the new created classification. In this regard, the interobserver reliability was determined for two independent raters in terms of Cohen Kappa. RESULTS: On the basis of the most widely recognized classifications of Su et al. as well as Lewis and Rorabeck, we established an implant-dependent classification for PPF of the distal femur. In accordance with the two stated classifications four fracture types were created and defined. Moreover, the four most frequent prosthesis types were integrated. Finally, a new classification with 16 subtypes was generated based on four types of fracture and four types of prosthesis. Considering all cases the presented implant-associated classification (kappa = 0.74) showed a considerably higher interobserver reliability compared to the other classifications of Su et al. (kappa = 0.39) as well as Lewis and Rorabeck (kappa = 0.31). Excluding the cases which were only assessable by the new classification, it still shows a higher interobserver reliability (kappa = 0.70) than the other ones (kappa = 0.63 or kappa = 0.45). CONCLUSIONS: The new classification system for PPF of the distal femur following TKA considers fracture location and implant type. It is easy to use, shows agood interobserver reliability and allows conclusions to be drawn on treatment recommendations. Moreover, further studies on the evaluation of the classification are necessary and planned. PMID- 29178861 TI - Contact stresses, pressure and area in a fixed-bearing total ankle replacement: a finite element analysis. AB - BACKGROUND: Mobile-bearing ankle implants with good clinical results continued to increase the popularity of total ankle arthroplasty to address endstage ankle osteoarthritis preserving joint movement. Alternative solutions used fixed bearing designs, which increase stability and reduce the risk of bearing dislocation, but with a theoretical increase of contact stresses leading to a higher polyethylene wear. The purpose of this study was to investigate the contact stresses, pressure and area in the polyethylene component of a new total ankle replacement with a fixed-bearing design, using 3D finite element analysis. METHODS: A three-dimensional finite element model of the Zimmer Trabecular Metal Total Ankle was developed and assembled based on computed tomography images. Three different sizes of the polyethylene insert were modeled, and a finite element analysis was conducted to investigate the contact pressure, the von Mises stresses and the contact area of the polyethylene component during the stance phase of the gait cycle. RESULTS: The peak value of pressure was found in the anterior region of the articulating surface, where it reached 19.8 MPa at 40% of the gait cycle. The average contact pressure during the stance phase was 6.9 MPa. The maximum von Mises stress of 14.1 MPa was reached at 40% of the gait cycle in the anterior section. In the central section, the maximum von Mises stress of 10.8 MPa was reached at 37% of the gait cycle, whereas in the posterior section the maximum stress of 5.4 MPa was reached at the end of the stance phase. DISCUSSION: The new fixed-bearing total ankle replacement showed a safe mechanical behavior and many clinical advantages. However, advanced models to quantitatively estimate the wear are need. CONCLUSION: To the light of the clinical advantages, we conclude that the presented prosthesis is a good alternative to the other products present in the market. PMID- 29178863 TI - Estimating disease burden of a potential A(H7N9) pandemic influenza outbreak in the United States. AB - BACKGROUND: Since spring 2013, periodic emergence of avian influenza A(H7N9) virus in China has heightened the concern for a possible pandemic outbreak among humans, though it is believed that the virus is not yet human-to-human transmittable. Till June 2017, A(H7N9) has resulted in 1533 laboratory-confirmed cases of human infections causing 592 deaths. The aim of this paper is to present disease burden estimates (measured by infection attack rates (IAR) and number of deaths) in the event of a possible pandemic outbreak caused by human-to-human transmission capability acquired by A(H7N9) virus. Even though such a pandemic will likely spread worldwide, our focus in this paper is to estimate the impact on the United States alone. METHOD: The method first uses a data clustering technique to divide 50 states in the U.S. into a small number of clusters. Thereafter, for a few selected states in each cluster, the method employs an agent-based (AB) model to simulate human A(H7N9) influenza pandemic outbreaks. The model uses demographic and epidemiological data. A few selected non pharmaceutical intervention (NPI) measures are applied to mitigate the outbreaks. Disease burden for the U.S. is estimated by combining results from the clusters applying a method used in stratified sampling. RESULTS: Two possible pandemic scenarios with R 0 = 1.5 and 1.8 are examined. Infection attack rates with 95% C.I. (Confidence Interval) for R 0 = 1.5 and 1.8 are estimated to be 18.78% (17.3 20.27) and 25.05% (23.11-26.99), respectively. The corresponding number of deaths (95% C.I.), per 100,000, are 7252.3 (6598.45-7907.33) and 9670.99 (8953.66 10,389.95). CONCLUSIONS: The results reflect a possible worst-case scenario where the outbreak extends over all states of the U.S. and antivirals and vaccines are not administered. Our disease burden estimations are also likely to be somewhat high due to the fact that only dense urban regions covering approximately 3% of the geographic area and 81% of the population are used for simulating sample outbreaks. Outcomes from these simulations are extrapolated over the remaining 19% of the population spread sparsely over 97% of the area. Furthermore, the full extent of possible NPIs, if deployed, could also have lowered the disease burden estimates. PMID- 29178862 TI - Prevalence and types of high-risk human papillomaviruses in head and neck cancers from Bangladesh. AB - BACKGROUND: There is a dramatic rise in the incidence of Human papillomavirus (HPV) - associated head and neck squamous cell carcinoma (HNSCC) in the world, with considerable variation by geography, gender and ethnicity. Little is known about the situation in Bangladesh, where tobacco- and areca nut-related head and neck cancers (HNCs) are the most common cancers in men. We aimed to determine the prevalence of HPV in HNSCC in Bangladesh and to explore the possible value of cell cycle markers in clinical diagnostic settings. METHODS: One hundred and ninety six archival HNSCC tissue samples were analysed for the presence of HPV DNA. The DNA quality was assured, and then amplified using a nested PCR approach. The typing of HPV was performed by automated DNA sequencing. Cellular markers p53, Cyclin D1 and pRb were tested on all samples by immunohistochemistry (IHC), as well as p16 as a putative surrogate for the detection of HPV. RESULTS: HPV DNA was detected in 36/174 (~21%) samples: 36% of cancers from the oropharynx; 31% of oral cancers, and 22% from the larynx. HPV-16 was most common, being present in 33 samples, followed by HPV-33 (2 samples) and HPV-31 (1 sample). Twenty-eight out of 174 samples were positive for p16, predominantly in HPV-positive tissues (p < 0.001). No statistically significant association was observed between the cellular markers and HPV DNA positive cases. However, p16 positivity had excellent predictive value for the presence of HPV by PCR. CONCLUSION: There is a significant burden of HPV-associated HNSCC in Bangladesh, particularly in the oropharynx but also in oral and laryngeal cancers. Whilst a combination of PCR based DNA detection and p16 IHC is useful, the latter has excellent specificity, acceptable sensitivity and good predictive value for carriage of HPV in this population and should be used for prognostic evaluation and treatment planning of all HNSCC patients in South Asia, as in the Western world. PMID- 29178864 TI - Musculoskeletal extremity pain in Danish school children - how often and for how long? The CHAMPS study-DK. AB - BACKGROUND: Musculoskeletal pain is common in childhood and adolescence, and may be long-lasting and recurrent. Musculoskeletal problems tend to follow adolescents into adulthood, and therefore it is important to design better prevention strategies and early effective treatment. To this end, we need in depth knowledge about the epidemiology of musculoskeletal extremity problems in this age group, and therefore, the aim of this study was to determine the prevalence, frequency and course of musculoskeletal pain in the upper and lower extremities in a cohort of Danish school children aged 8-14 years at baseline. METHODS: This was a prospective 3-year school-based cohort study, with information about musculoskeletal pain collected in two ways. Parents answered weekly mobile phone text messages about the presence or absence of musculoskeletal pain in their children, and a clinical consultation was performed in a subset of the children. RESULTS: We found that approximately half the children had lower extremity pain every study year. This pain lasted on average for 8 weeks out of a study year, and the children had on average two and a half episodes per study year. Approximately one quarter of the children had upper extremity pain every study year that lasted on average 3 weeks during a study year, with one and a half episodes being the average. In general, there were more non-traumatic pain episodes compared with traumatic episodes in the lower extremities, whereas the opposite was true in the upper extremities. The most common anatomical pain sites were 'knee' and 'ankle/ft'. CONCLUSION: Lower extremity pain among children and adolescents is common, recurrent and most often of non-traumatic origin. Upper extremity pain is less common, with fewer and shorter episodes, and usually with a traumatic onset. Girls more frequently reported upper extremity pain, whereas there was no sex-related difference in the lower extremities. The most frequently reported locations were 'knee' and 'ankle/ft'. PMID- 29178865 TI - Palliative care for patients with Parkinson's disease: study protocol for a mixed methods study. AB - BACKGROUND: Parkinson's disease (PD) is a chronic, progressive neurological disorder with many intractable consequences for patients and their family caregivers. Little is known about the possibilities that palliative care could offer to patients and their proxies. Guidelines strongly recommend palliative care to improve the quality of life and - if needed - the quality of dying. However, providing palliative care to persons with PD involves specific challenges. For example, a timely initiation of palliative interventions is difficult because due to the gradually progressive nature of PD, there is often no clear marker for the transition from curative towards palliative care. Furthermore, there is little evidence to indicate which palliative care interventions are effective. Here, we describe the contours of a study that aims to examine the experiences of patients, (bereaved) family caregivers and professionals, with the aim of improving our knowledge about palliative care needs in PD. METHODS/DESIGN: We will perform a mixed methods study to evaluate the experiences of patients, (bereaved) family caregivers and palliative care professionals. In this study, we focus on Quality of Life, Quality of Care, perceived symptoms, caregiver burden and collaboration between professionals. In phase 1, we will retrospectively explore the views of bereaved family caregivers and professionals by conducting individual interviews and focus group interviews. In phase 2, 5-15 patients with PD and their family caregiver will be followed prospectively for 8-12 months. Data collection will involve semi-structured interviews and questionnaires at three consecutive contact moments. Qualitative data will be audio recorded, transcribed and analyzed using CAQDAS. If patients pass away during the study period, a bereavement interview will be done with the closest family caregiver. DISCUSSION: This study will offer a broad perspective on palliative care, and the results can be used to inform a palliative care protocol for patients with PD. By describing the experiences of patients, (bereaved) family caregivers and professionals with palliative care, this investigation will also establish an important ground for future intervention research. PMID- 29178866 TI - A scoping review of palliative care for children in low- and middle-income countries. AB - BACKGROUND: Ninety-eight percent of children needing palliative care live in low- and middle-income countries (LMICs), and almost half of them live in Africa. In contrast to the abundance of data on populations in high income countries, the current data on populations in LMICs is woefully inadequate. This study aims to identify and summarize the published literature on the need, accessibility, quality, and models for palliative care for children in LMICs. METHODS: A scoping review was performed following the method of Arksey and O'Malley. Systematic searches were conducted on PubMed and Google Scholar using the main keywords, 'children AND palliative care OR terminal care OR hospice OR end of life AND developing countries OR LMICs.' Additional publications were obtained by handsearching. Papers were only included if they reported on the need, accessibility, quality, and models for palliative care for children in LMICs. RESULTS: Fifteen papers met the inclusion criteria for review. Of these, 10 assessed need, seven examined availability and/or accessibility, one assessed quality, and one examined the models. We found an urgent need for palliative care, particularly in the training for health workers and improving poor availability and/or accessibility to palliative care in terms of factors such as medication and bereavement support. The best practice models demonstrated feasibility and sustainability through cooperation with governments and community organizations. The quality of pain management and emotional support was lower in LMICs compared to HICs. CONCLUSION: Although we found limited evidence in this review, we identified common challenges such as the need for further training for health workers and greater availability of opioid analgesics. While efforts to change the current systems and laws applying to children in LMICs are important, we should also tackle underlying factors including the need to raise awareness about palliative care in public health and improve the accuracy of data collection. PMID- 29178867 TI - Does objectively measured physical activity modify the association between early weight gain and fat mass in young adulthood? AB - BACKGROUND: Substantial evidence suggests that weight gain in early life is associated with increased adiposity and other metabolic disorders later in life. It is, however, unknown whether physical activity (PA) may modify these associations. We aimed to examine whether objectively measured PA at 30 years modified the associations between conditional weight gain in infancy (0-2 y) and childhood (2-4 y) with fat mass index (FMI) and visceral abdominal fat measured at age 30 years. METHODS: Prospective birth cohort study in Pelotas, Brazil, including 1874 participants with weight data at birth, two and four years of age, and measures of FMI, visceral abdominal fat and PA at a mean age of 30.2 years. At age 30, time spent (min/day) in moderate-to-vigorous physical activity (MVPA) was measured objectively using a wrist-worn accelerometer worn for four to seven consecutive days.. Multiple linear regression analyses was performed to assess the associations between conditional weight gain and outcome variables at 30 years, adjusting for covariates. We examined whether PA modified the association between conditional weight gain and the outcomes of interest by introducing an interaction term (conditional weight gain * PA) in the models. RESULTS: Conditional weight gain in infancy and childhood were both positively associated with later FMI (infancy weight gain: beta = 0.68, 95% CI: 0.48, 0.88; P < 0.001; childhood weight gain: beta = 0.91, 95% CI: 0.70, 1.11; P < 0.001). A formal test for interaction suggested that MVPA at 30 years of age modified the association between childhood relative weight gain and later FMI (beta = -0.006, 95% CI: 0.011, -0.001; P = 0.029), suggesting stronger associations between weight gain and FMI in those with lower levels of MVPA. Conditional weight gain in childhood was also positively associated with visceral abdominal fat (beta = 0.24, 95% CI: 0.15, 0424, P < 0.001). There was no evidence for a modification of the latter association after adjustment for physical activity. CONCLUSION: Conditional weight gain between 2 and 4 years of age is associated with increased FMI at age 30 years. However, higher levels of MVPA appear to attenuate this detrimental association. PMID- 29178868 TI - Derivation and validation of the Personal Support Algorithm: an evidence-based framework to inform allocation of personal support services in home and community care. AB - BACKGROUND: Personal support services enable many individuals to stay in their homes, but there are no standard ways to classify need for functional support in home and community care settings. The goal of this project was to develop an evidence-based clinical tool to inform service planning while allowing for flexibility in care coordinator judgment in response to patient and family circumstances. METHODS: The sample included 128,169 Ontario home care patients assessed in 2013 and 25,800 Ontario community support clients assessed between 2014 and 2016. Independent variables were drawn from the Resident Assessment Instrument-Home Care and interRAI Community Health Assessment that are standardised, comprehensive, and fully compatible clinical assessments. Clinical expertise and regression analyses identified candidate variables that were entered into decision tree models. The primary dependent variable was the weekly hours of personal support calculated based on the record of billed services. RESULTS: The Personal Support Algorithm classified need for personal support into six groups with a 32-fold difference in average billed hours of personal support services between the highest and lowest group. The algorithm explained 30.8% of the variability in billed personal support services. Care coordinators and managers reported that the guidelines based on the algorithm classification were consistent with their clinical judgment and current practice. CONCLUSIONS: The Personal Support Algorithm provides a structured yet flexible decision-support framework that may facilitate a more transparent and equitable approach to the allocation of personal support services. PMID- 29178869 TI - The potential impact of food taxes and subsidies on cardiovascular disease and diabetes burden and disparities in the United States. AB - BACKGROUND: Fiscal interventions are promising strategies to improve diets, reduce cardiovascular disease and diabetes (cardiometabolic diseases; CMD), and address health disparities. The aim of this study is to estimate the impact of specific dietary taxes and subsidies on CMD deaths and disparities in the US. METHODS: Using nationally representative data, we used a comparative risk assessment to model the potential effects on total CMD deaths and disparities of price subsidies (10%, 30%) on fruits, vegetables, whole grains, and nuts/seeds and taxes (10%, 30%) on processed meat, unprocessed red meats, and sugar sweetened beverages. We modeled two gradients of price-responsiveness by education, an indicator of socioeconomic status (SES), based on global price elasticities (18% greater price-responsiveness in low vs. high SES) and recent national experiences with taxes on sugar-sweetened beverages (65% greater price responsiveness in low vs. high SES). RESULTS: Each price intervention would reduce CMD deaths. Overall, the largest proportional reductions were seen in stroke, followed by diabetes and coronary heart disease. Jointly altering prices of all seven dietary factors (10% each, with 18% greater price-responsiveness by SES) would prevent 23,174 (95% UI 22,024-24,595) CMD deaths/year, corresponding to 3.1% (95% UI 2.9-3.4) of CMD deaths among Americans with a lower than high school education, 3.6% (95% UI 3.3-3.8) among high school graduates/some college, and 2.9% (95% UI 2.7-3.5) among college graduates. Applying a 30% price change and larger price-responsiveness (65%) in low SES, the corresponding reductions were 10.9% (95% UI 9.2-10.8), 9.8% (95% UI 9.1-10.4), and 6.7% (95% UI 6.2-7.6). The latter scenario would reduce disparities in CMD between Americans with lower than high school versus a college education by 3.5 (95% UI 2.3-4.5) percentage points. CONCLUSIONS: Modest taxes and subsidies for key dietary factors could meaningfully reduce CMD and improve US disparities. PMID- 29178870 TI - Clinical factors contributing to high cost hospitalizations in a Canadian tertiary care centre. AB - BACKGROUND: Like much of the developed world, healthcare costs in Canada are rising. A small proportion of patients account for a large proportion of healthcare spending and much of this spending occurs in acute care settings. The purpose of our study was to determine potentially modifiable factors related to care processes that contribute to high-cost admissions. METHODS: Using a mixed methods study design, factors contributing to high-cost admissions were identified from literature and case review. We defined pre- and post-admission factors contributing to high-cost admissions. Pre-admission factors included reason for admission (e.g. complex medical, elective surgery, trauma, etc.). Post admission factors included medical complications, disposition delays, clinical services delays, and inefficient clinical decision-making. We selected a random sample of admissions in the top decile of inpatient cost from the Ottawa Hospital between January 1 and December 31, 2010. A single reviewer classified cases based on the pre- and post-admission factors. We combined this information with data derived from the Ottawa Hospital Data Warehouse to describe patient-level clinical and demographic characteristics and costs incurred. RESULTS: We reviewed 200 charts which represents ~5% of all high cost admissions within the Ottawa Hospital in 2010. Post-admission factors contributing to high-cost admissions were: complications (60%), disposition delays (53%), clinical service delays (39%), and inefficient clinical decision-making (13%). Further, these factors varied substantially across service delivery lines. The mean (standard deviation (SD)) cost per admission was $49,923 CDN ($45,773). The most common reason for admission was "complex medical" (49%) and the overall median (IQR) length of stay was 27 (18-48) days. Approximately 1 in 3 high cost admissions (29%) included time in the intensive care unit (ICU). CONCLUSIONS: While high cost admissions often include time in ICU and have long lengths of stay, a substantial proportion of costs were attributable to complications and potentially preventable delays in care processes. These findings suggest opportunities exist to improve outcomes and reduce costs for this diverse patient population. PMID- 29178871 TI - Efficacy and safety of tiotropium and olodaterol in COPD: a systematic review and meta-analysis. AB - BACKGROUND: Long-acting bronchodilators are the cornerstone of pharmacologic treatment of COPD. The new combination of long-acting muscarinic antagonist (LAMA) tiotropium (TIO) and long acting beta-agonists (LABA) olodaterol (OLO) has been introduced as fist line therapy for COPD. This article analyses the evidence of efficacy and safety of the TIO/OLO combination. METHODS: A systematic review and metaanalysis of randomized controlled trials (RCT) with a period of treatment of at least 6 weeks, in patients with COPD confirmed by spirometry, comparing combined treatment with TIO/OLO (approved doses only), with any of the mono components or any other active comparator administered as an inhalator. RESULTS: A total of 10 Randomized controlled trials (RCT) were identified (N = 10,918). TIO/OLO significantly improved trough FEV1 from baseline to week 12 versus TIO, OLO and LABA/ICS (0.06 L, 0.09 L and between 0.04 and 0.05 L, respectively). TIO/OLO improved transitional dyspnea index (TDI) and St. George's Respiratory Questionnaire (SGRQ) compared with mono-components, with patients more likely to achieve clinically important improvements in TDI (risk ratio [RR]: 1.17, 95% confidence interval [CI]: [1.07, 1.28] versus TIO and RR: 1.14, 95%CI: [1.01, 1.28] versus OLO) and in SGRQ (RR: 1.21, 95%CI: [1.12, 1.30] versus TIO and RR: 1.28, 95%CI: [1.18, 1.40] versus OLO). Patients treated with TIO/OLO showed a significant reduction in the use of rescue medication and no significant differences in frequency of general and serious adverse events were observed between TIO/OLO and mono-components. CONCLUSIONS: Treatment with TIO/OLO provided significant improvements in lung function versus mono-components and LABA/ICS with more patients achieving significant improvements in dyspnea and health status. No differences in adverse events were observed compared with other active treatments. CLINICAL TRIAL REGISTRATION: PROSPERO register of systematic reviews ( CRD42016040162 ). PMID- 29178872 TI - MitoCore: a curated constraint-based model for simulating human central metabolism. AB - BACKGROUND: The complexity of metabolic networks can make the origin and impact of changes in central metabolism occurring during diseases difficult to understand. Computer simulations can help unravel this complexity, and progress has advanced in genome-scale metabolic models. However, many models produce unrealistic results when challenged to simulate abnormal metabolism as they include incorrect specification and localisation of reactions and transport steps, incorrect reaction parameters, and confounding of prosthetic groups and free metabolites in reactions. Other common drawbacks are due to their scale, making them difficult to parameterise and simulation results hard to interpret. Therefore, it remains important to develop smaller, manually curated models. RESULTS: We present MitoCore, a manually curated constraint-based computer model of human metabolism that incorporates the complexity of central metabolism and simulates this metabolism successfully under normal and abnormal physiological conditions, including hypoxia and mitochondrial diseases. MitoCore describes 324 metabolic reactions, 83 transport steps between mitochondrion and cytosol, and 74 metabolite inputs and outputs through the plasma membrane, to produce a model of manageable scale for easy interpretation of results. Its key innovations include a more accurate partitioning of metabolism between cytosol and mitochondrial matrix; better modelling of connecting transport steps; differentiation of prosthetic groups and free co-factors in reactions; and a new representation of the respiratory chain and the proton motive force. MitoCore's default parameters simulate normal cardiomyocyte metabolism, and to improve usability and allow comparison with other models and types of analysis, its reactions and metabolites have extensive annotation, and cross-reference identifiers from Virtual Metabolic Human database and KEGG. These innovations-including over 100 reactions absent or modified from Recon 2-are necessary to model central metabolism more accurately. CONCLUSION: We anticipate MitoCore as a research tool for scientists, from experimentalists looking to interpret their data and test hypotheses, to experienced modellers predicting the consequences of disease or using computationally intensive methods that are infeasible with larger models, as well as a teaching tool for those new to modelling and needing a small, manageable model on which to learn and experiment. PMID- 29178873 TI - Prevalence and molecular characterization of Staphylococcus aureus isolated from goats in Chongqing, China. AB - BACKGROUND: Staphylococcus aureus is an important zoonotic pathogen which not only causes significant economic loss in livestock production but also poses a potential threat to public health. Compared with bovine and swine, the information on the colonization of S. aureus in goats is very limited. To understand the prevalence and characteristics of S. aureus in goats, we used the nasal swabs collected from apparently healthy goats to isolate S. aureus, and tested their antimicrobial susceptibility, virulence gene carrying levels, and multilocus sequence typing (MLST). RESULTS: In 74 nasal swabs of apparently healthy goats, 32 (43.24%) S. aureus strains were isolated and identified, most of which were susceptible to many antibiotics, except for trimethoprim, furazolidone, amoxicillin, lincomycin and roxithromycin, and the resistance incidence of which were 50%, 40.63%, 37.5%, 28.13%, and 21.88% respectively. All the isolates were methicillin-susceptible S. aureus (MSSA) and mecA-negative. Enterotoxin genes were found in 53.13% of the strains. Of which, sej was the most prevalent (21.88%), followed by seb, sec, and see with the same level (18.75%). The most prevalent combination were seb + see and seb + tst. None of the S. aureus isolates harbored sea, sed, seh, eta and etb. Multilocus sequence typing (MLST) revealed 6 new alleles (aroe-552, aroe-553, glpf-500, pta-440, yqil-482 and yqil-496) and 5 new sequence types (STs) (3431,3440,3444,3445 and 3461). Using eBURST, the 5 STs were assigned to clonal complex 522 (CC522) and a further CC with no predicted ancestor. Phylogenetic analysis of seven concatenated MLST alleles revealed that the 5 STs were grouped into cluster I composed of S. aureus mainly from goats and sheep. CONCLUSION: We provide the data for prevalence of S. aureus in goats in Chongqing municipality and their characterization which will help in tracking evolution of epidemic strains and their control methods. PMID- 29178874 TI - Reference gene validation for gene expression normalization in canine osteosarcoma: a geNorm algorithm approach. AB - BACKGROUND: Quantitative PCR (qPCR) is a common method for quantifying mRNA expression. Given the heterogeneity present in tumor tissues, it is crucial to normalize target mRNA expression data using appropriate reference genes that are stably expressed under a variety of pathological and experimental conditions. No studies have validated specific reference genes in canine osteosarcoma (OS). Previous gene expression studies involving canine OS have used one or two reference genes to normalize gene expression. This study aimed to validate a panel of reference genes commonly used for normalization of canine OS gene expression data using the geNorm algorithm. qPCR analysis of nine canine reference genes was performed on 40 snap-frozen primary OS tumors and seven cell lines. RESULTS: Tumors with a variety of clinical and pathological characteristics were selected. Gene expression stability and the optimal number of reference genes for gene expression normalization were calculated. RPS5 and HNRNPH were highly stable among OS cell lines, while RPS5 and RPS19 were the best combination for primary tumors. Pairwise variation analysis recommended four and two reference genes for optimal normalization of the expression data of canine OS tumors and cell lines, respectively. CONCLUSIONS: Appropriate combinations of reference genes are recommended to normalize mRNA levels in canine OS tumors and cell lines to facilitate standardized and reliable quantification of target gene expression, which is essential for investigating key genes involved in canine OS metastasis and for comparative biomarker discovery. PMID- 29178875 TI - Metabolic engineering of Synechococcus elongatus PCC 7942 for improvement of 1,3 propanediol and glycerol production based on in silico simulation of metabolic flux distribution. AB - BACKGROUND: Production directly from carbon dioxide by engineered cyanobacteria is one of the promising technologies for sustainable future. Previously, we have successfully achieved 1,3-propanediol (1,3-PDO) production using Synechococcus elongatus PCC 7942 with a synthetic metabolic pathway. The strain into which the synthetic metabolic pathway was introduced produced 3.48 mM (0.265 g/L) 1,3-PDO and 14.3 mM (1.32 g/L) glycerol during 20 days of incubation. In this study, the productivities of 1,3-PDO were improved by gene disruption selected by screening with in silico simulation. METHODS: First, a stoichiometric metabolic model was applied to prediction of cellular metabolic flux distribution in a 1,3-PDO producing strain of S. elongatus PCC 7942. A genome-scale model of S. elongatus PCC 7942 constructed by Knoop was modified by the addition of a synthetic metabolic pathway for 1,3-PDO production. Next, the metabolic flux distribution predicted by metabolic flux balance analysis (FBA) was used for in silico simulation of gene disruption. As a result of gene disruption simulation, NADPH dehydrogenase 1 (NDH-1) complexes were found by screening to be the most promising candidates for disruption to improve 1,3-PDO production. The effect of disruption of the gene encoding a subunit of the NDH-1 complex was evaluated in the 1,3-PDO-producing strain. RESULTS AND CONCLUSIONS: During 20 days of incubation, the ndhF1-null 1,3-PDO-producing strain showed the highest titers: 4.44 mM (0.338 g/L) 1,3-PDO and 30.3 mM (2.79 g/L) glycerol. In this study, we successfully improved 1,3-PDO productivity on the basis of in silico simulation of gene disruption. PMID- 29178876 TI - Urban-rural difference in satisfaction with primary healthcare services in Ghana. AB - BACKGROUND: Understanding regional variation in patient satisfaction about healthcare systems (PHCs) on the quality of services provided is instrumental to improving quality and developing a patient-centered healthcare system by making it more responsive especially to the cultural aspects of health demands of a population. Reaching to the innovative National Health Insurance Scheme (NHIS) in Ghana, surpassing several reforms in healthcare financing has been a milestone. However, the focus of NHIS is on the demand side of healthcare delivery. Studies focusing on the supply side of healthcare delivery, particularly the quality of service as perceived by the consumers are required. A growing number of studies have focused on regional differences of patient satisfaction in developed countries, however little research has been conducted concerning patient satisfaction in resource-poor settings like in Ghana. This study was therefore dedicated to examining the variation in satisfaction across rural and urban women in Ghana. METHODS: Data for the present study were obtained from the latest demographic and health survey in Ghana (GDHS 2014). Participants were 3576 women aged between 15 and 49 years living in non-institutional settings in Ghana. Summary statistics in percentages was used to present respondents' demographic, socioeconomic characteristics. Chi-square test was used to find association between urban-rural differentials with socio-economic variables. Multiple logistic regression was performed to measure the association of being satisfied with primary healthcare services with study variables. Model fitness was tested by pseudo R 2. Statistical significance was set at p < 0.05. RESULTS: The findings in this study revealed that about 57.1% were satisfied with primary health care services. The urban and rural areas reported 57.6 and 56.6% respectively which showed no statistically significant difference (z = 0.64; p = 0.523; 95%CI: -0.022, 0.043). Bivariate analysis showed that region, highest level of education, wealth index and type of facility were significantly associated with location of residence (urban-rural areas). After adjusting for confounding variables using logistic regression, geographical location became a key factor of satisfaction with primary healthcare services by location of residence. In urban areas, respondents from Greater Accra had 64% increase in the level of satisfaction when compared to those in Western region (OR = 1.64; 95CI: 1.09-2.47), Upper East had 75% increase in satisfaction compared to Western region (OR = 1.75; 95%CI: 1.08-2.84), Northern had an estimated 44% reduction in satisfaction when compared to Western region (OR = 0.56; 95%CI: 0.34-0.92). However, rural areas in Central, Volta, Eastern, Ashanti, Brong Aghafo, Northern and Upper West region had 51, 81, 69, 46, 62, 75 and 61% reduction respectively in the level of satisfaction when compared to Western region. CONCLUSIONS: Patient satisfaction is an important indicator of health outcomes. Quality of care and measuring level of patient satisfaction has been found to be the most useful tool to predict utilization and compliance. In fact, satisfied patients are more likely than unsatisfied ones to continue using health care services. Our results suggest that policymakers need to better understand the determinants of satisfaction with the health system and how different socio-demographic groups perceive satisfaction with healthcare services so as to address health inequalities between urban and rural areas within the same country. PMID- 29178877 TI - Non-sterilized fermentation of high optically pure D-lactic acid by a genetically modified thermophilic Bacillus coagulans strain. AB - BACKGROUND: Optically pure D-lactic acid (>= 99%) is an important precursor of polylactic acid. However, there are relatively few studies on D-lactic acid fermentation compared with the extensive investigation of L-lactic acid production. Most lactic acid producers are mesophilic organisms. Optically pure D lactic acid produced at high temperature not only could reduce the costs of sterilization but also could inhibit the growth of other bacteria, such as L lactic acid producers. RESULTS: Thermophilic Bacillus coagulans is an excellent producer of L-lactic acid with capable of growing at 50 degrees C. In our previous study, the roles of two L-lactic acid dehydrogenases have been demonstrated in B. coagulans DSM1. In this study, the function of another annotated possible L-lactate dehydrogenase gene (ldhL3) was verified to be leucine dehydrogenase with an activity of 0.16 units (MUmol/min) per mg protein. Furthermore, the activity of native D-lactate dehydrogenase was too low to support efficient D-lactic acid production, even under the control of strong promoter. Finally, an engineered B. coagulans D-DSM1 strain with the capacity for efficient production of D-lactic acid was constructed by deletion of two L lactate dehydrogenases genes (ldhL1 and ldhL2) and insertion of the D-lactate dehydrogenase gene (LdldhD) from Lactobacillus delbrueckii subsp. bulgaricus DSM 20081 at the position of ldhL1. CONCLUSIONS: This genetically engineered strain produced only D-lactic acid under non-sterilized condition, and finally 145 g/L of D-lactic acid was produced with an optical purity of 99.9% and a high yield of 0.98 g/g. This is the highest optically pure D-lactic acid titer produced by a thermophilic strain. PMID- 29178878 TI - Trypsin-independent porcine epidemic diarrhea virus US strain with altered virus entry mechanism. AB - BACKGROUND: Porcine Epidemic Diarrhea Virus (PEDV) is a coronavirus that infects the intestinal tract and causes diarrhea and vomiting in older pigs or extreme dehydration and death that could reach 100% mortality in neonatal piglets. In the US, the first PEDV outbreaks occurred in 2013 and since then US PEDV strains have quickly spread throughout the US and worldwide, causing significant economic and public health concerns. Currently two conditionally approved vaccines exist in the US, but there is no live attenuated vaccine, which is considered the best option in controlling PEDV by inducing transferrable mucosal immunity to susceptible neonatal piglets. In this study, we passaged an US PEDV isolate under various conditions to generate three strains and characterized their growth and antigenicity in cell culture using various assays including Western blot analysis, serum neutralization assay, sequencing analysis and confocal microscopy. Finally, these strains were evaluated for pathogenicity in nursing piglets (1-4 days old). RESULTS: One of the PEDV strains generated in this study (designated as PEDV 8aa) is able to replicate in cells without any protease and grows to a high titer of >8 log10 TCID50/ml in cell culture. Interestingly, replication of PEDV 8aa was severely reduced by trypsin and this correlated with the inhibition of virus attachment and entry into the cells. In neonatal nursing piglets, PEDV 8aa (passage number 70 or 105) was found to be fully attenuated with limited virus shedding. CONCLUSIONS: These results suggest that applying selective pressure during viral passages can facilitate attainment of viral attenuation and that PEDV 8aa warrants further investigation as an attenuated vaccine. PMID- 29178879 TI - Residual renal function in chronic dialysis is not associated with reduced erythropoietin-stimulating agent dose requirements: a cross-sectional study. AB - BACKGROUND: Anaemia is a very common problem in patients with end-stage kidney disease (ESKD) and the use of erythropoietin-stimulating agents (ESA) has revolutionised its treatment. Residual renal function (RRF) is associated with a reduction in ESA resistance and mortality in chronic dialysis. The primary aim was to establish whether RRF has an association with ESA dose requirements in ESKD patients receiving chronic dialysis. METHODS: A single center, cross sectional study involving 100 chronic dialysis patients was conducted from December 2015 to May 2016. Participants were divided into two groups depending on presence of RRF, which was defined as a 24-h urine sample volume of >= 100 ml. Erythropoietin resistance index [ERI = total weekly ESA dose (IU)/weight (kg)/haemoglobin concentration (g/dL] was used as a measure of ESA dose requirements. RESULTS: There was no difference in ERI between those with RRF as compared to those without (9.5 versus 11.0, respectively; P = 0.45). Also, ERI did not differ between those receiving haemodialysis as compared with peritoneal dialysis (10.8 versus 10.2, respectively; P = 0.84) or in those using renin angiotensin system (RAS) blockers as compared with no RAS blocker use (11.6 versus 9.2, respectively; P = 0.10). Lower ERI was evident for those with cystic kidney disease as compared to those with other causes of ESKD (6.9 versus 16.5, respectively; P = 0.32) although this did not reach statistical significance. Higher ERI was found in those with evidence of systemic inflammation as compared to those without (16.5 versus 9.5, respectively; P = 0.003). CONCLUSIONS: There was no association between RRF and ESA dose requirements, irrespective of dialysis modality, RAS blocker use, primary renal disease or hyperparathyroidism. PMID- 29178880 TI - Evaluation of effects of Mycoplasma mastitis on milk composition in dairy cattle from South Australia. AB - BACKGROUND: Mycoplasma mastitis is increasingly posing significant impact on dairy industry. Although the effects of major conventional mastitis pathogens on milk components has been widely addressed in the literature, limited data on the effects of different Mycoplasma and Acholeplasma spp. on milk quality and quantity is available. The aim of this study was to determine the casual relationship of Mycoplasma spp. and A. laidlawii to mastitis and compare them to subclinical mastitis caused by conventional mastitis pathogens from a single dairy herd in South Australia; Mycoplasma spp. and A. laidlawii were detected using PCR applied directly to milk samples. The herd had mastitis problem with high somatic cell count and low response rate to conventional antimicrobial therapy. A total of 288 cow-level milk samples were collected aseptically and used in this study. RESULTS: Conventional culture showed a predominance of coagulase-negative staphylococci, followed by coagulase-positive staphylococci, Streptococcus spp., Enterococcus spp., E. coli, and Klebsiella spp. PCR results showed a high prevalence of mycoplasmas (76.7%), including A. laidlawii (10.8%), M. bovis (6.2%), M. bovirhinis (5.6%), M. arginini (2%), and (52.1%) of cows were co-infected with two or more Mycoplasma and Acholeplasma species. Mycoplasma co infection significantly increased somatic cell counts (SCC) similar to conventional mastitis pathogens and compared to non-infected cows with 389.3, 550.3 and 67.3 respectively; and decreased the milk yield with 29.0, 29.9 and 34.4 l, respectively. Mycoplasma co-infection caused significant increase in protein percentage, and significant decrease in fat percentage and total milk solids, similar to other conventional mastitis pathogens. In contrast, changes in milk composition and yield caused by various individual Mycoplasma species were non-significant. CONCLUSIONS: Mycoplasma mastitis had on-farm economic consequences similar to common conventional mastitis pathogens. Results of our study indicate that co-infection Mycoplasma mastitis caused similar effect on milk composition to other mastitis pathogens and we hope these findings raise the awareness of the importance of their detection on routine diagnostic panels. PMID- 29178881 TI - Atrial ERK1/2 activation in the embryo leads to incomplete Septal closure: a novel mouse model of atrial Septal defect. AB - BACKGROUND: MEK1 mutation and activated MAPK signaling has been found in patients with RASopathies and abnormal cardiac development. Previous studies have suggested that regulation of fetal MAPK signaling is essential for normal cardiac development. We investigated the effect of active MEK1 overexpression on fetal atrial septal development. METHODS AND RESULTS: An inducible double transgenic (DTg) mouse model was developed in which cardiac-specific fetal expression of a constitutively active form of human MEK1 (aMEK1) was induced primarily in the atrium via the withdrawal of doxycycline from the drinking water of pregnant mice. Atrial septal defect (ASD) was found in 51% (23/45) of DTg mice. Fifty-two percent (12/23) of ASD mice died before weaning, and surviving ASD mice exhibited hypertrophic hearts with enlarged right atria and decreased fractional shorting (40 +/- 2% vs. 48 +/- 0%, p < 0.05). The model mimicked human ASD in several key clinical features: severe ASD was associated with growth impairment; ASD-specific mortality was highest within the early postnatal period; despite an even distribution of ASD among the sexes, early mortality was significantly higher in males. The expression of aMEK1 and increased phosphorylation of ERK1/2 was documented via Western blot in DTg fetal hearts, with the largest increases seen in atrial tissue. In an alternative transgenic aMEK1 model with elevated atrial MKP3 expression and corresponding suppression of increases in ERK1/2 phosphorylation, animals did not develop ASD. CONCLUSION: This new model of ASD suggests that enhanced atrial MEK1-ERK1/2 signaling during fetal development disrupts normal atrial septation, possibly regulated by the balance of ERK1/2 phosphorylation. PMID- 29178882 TI - Characterization and susceptibility of streptococci and enterococci isolated from Nile tilapia (Oreochromis niloticus) showing septicaemia in aquaculture and wild sites in Egypt. AB - BACKGROUND: The present investigation was an endeavor into the elucidation of the disease-causing pathogen of streptococcosis in Nile tilapia (Oreochromis niloticus) in Egypt affecting adult fish cultured and wild fish in the Nile river. Fish were obtained from commercial fishermen, collected as part of their routine fishing activities. The researchers observed the routine fishing process and selected fish for use in the study, at the point of purchase from the fisherman. RESULTS: Diseased fish showed exophthalmia with accumulation of purulent and haemorrhagic fluid around eyes, and ventral petechial haemorrhages. The Post mortem examination revealed, abdominal fat haemorrhage, pericarditis and enlargement of the liver, spleen and kidney. Gram-stained smears revealed the presence of Gram-positive cocci, beta-hemolytic, oxidase and catalase negative. Analysis of the 16S rRNA gene confirmed that the 17 tilapia isolates studied were 6/17 Enterococcus faecalis, 2/17 Enterococcus gallinarum, 3/17 Streptococcus pluranimalium, 2/17 Aerococcus viridans, 1/17 isolate of each Streptococcus dysgalactiae, Streptococcus anginosus, Lactococcus garvieae and Granulicetella elegans/Leuconostoc mesenteroides cremoris. It should be noted that there was no mixed infection. Multiple resistance was observed and the most frequent antibiotic combination was penicillin, ampicillin, vancomycin, chloramphenicol, rifampicin, ofloxacin, clindamycin, erythromycin and tetracycline representing eight classes. CONCLUSIONS: Consequently, we concluded that Streptococcus species are an emerging pathogen for Nile tilapia aquaculture in Egypt and to be considered as a new candidate in the warm water fish diseases in Egypt with special reference to L. garvieae, S. dysgalactiae in addition to L. mesenteroides cremoris which was not reported before from tilapia and taking into consideration their zoonotic implications for public health. PMID- 29178883 TI - Whole genome sequence and a phylogenetic analysis of the G8P[14] group A rotavirus strain from roe deer. AB - BACKGROUND: Group A rotaviruses (RVA) are associated with acute gastroenteritis in children and in young domestic and wild animals. A RVA strain was detected from a roe deer for the first time during a survey of game animals in Slovenia in 2014. A further RVA strain (SLO/D110-15) was detected from a roe deer during 2015. The aim of this study was to provide a full genetic profile of the detected RVA strain from roe deer and to obtain additional information about zoonotic transmitted strains and potential reassortments between human rotavirus strains and zoonotic transmitted rotavirus strains. The next generation sequencing (NGS) analysis on Ion Torrent was performed and the whole genome sequence has been determined together with a phylogenetic analysis. RESULTS: The whole genome sequence of SLO/D110-15 was obtained by NGS analyses on an IonTorrent platform. According to the genetic profile, the strain SLO/D110-15 clusters with the DS-1 like group and expresses the G8-P[14]-I2-R2-C2-M2-A3-N2-T6-E2-H3 genome constellation. Phylogenetic analysis shows that this roe deer G8P[14] strain is most closely related to RVA strains found in sheep, cattle and humans. A human RVA strain with the same genotype profile was detected in 2009 in Slovenia. CONCLUSIONS: The G8P[14] genotype has been found, for the first time, in deer, a newly described host from the order Artiodactyla for this RVA genotype. The finding of a rotavirus with the same genome segment constellation in humans indicates the possible zoonotic potential of this virus strain. PMID- 29178884 TI - A new panel of SNPs to assess thyroid carcinoma risk: a pilot study in a Brazilian admixture population. AB - BACKGROUND: Thyroid cancer is a common malignant disease of the endocrine system with increasing incidence rates over the last few decades. In this study, we sought to analyze the possible association of 45 single nucleotide polymorphisms (SNPs) with thyroid cancer in a population from Rio Grande do Norte, Brazil. METHODS: Based on histological analysis by a pathologist, 80 normal thyroid specimens of tissue adjacent to thyroid tumors were obtained from the biobank at the Laboratory of Pathology of Liga Norte Riograndense Contra o Cancer, Natal, RN. Patient samples were then genotyped using the MassARRAY platform (Sequenon, Inc) followed by statistical analysis employing the SNPassoc package in R program. The genotypic frequencies of all 45 SNPs obtained from the International HapMap Project database and based on data from the ancestral populations of European and African origin were used to compose the control study group. RESULTS: In our study, the following 9 SNPs showed significant differences in their frequency when comparing the study and control groups: rs3744962, rs258107, rs1461855, rs4075022, rs9943744, rs4075570, rs2356508, rs17485896, and rs2651339. Furthermore, the SNPs rs374492 C/T and rs258107 C/T were associated with a relative risk for thyroid carcinoma of 3.78 (p = 6.27 * 10e-5) and 2.91 (p = 8.27 * 10e-5), respectively, after Bonferroni's correction for multiple comparisons. CONCLUSIONS: These nine polymorphisms could be potential biomarkers of predisposition to thyroid carcinoma in the population from Rio Grande do Norte. However, complementary studies including a control group with samples obtained from healthy subjects in Rio Grande do Norte state, should be conducted to confirm these results. PMID- 29178885 TI - Severe maternal outcomes and quality of care at district hospitals in Rwanda- a multicentre prospective case-control study. AB - BACKGROUND: Despite a significant decrease in maternal mortality in the last decade, Rwanda needs further progress in order to achieve Sustainable Development Goals (SDG)3 which addresses among others maternal mortality. Analysis of severe maternal outcomes (SMO) was performed to identify their characteristics, causes and contributory factors, using standard indicators for quality of care. METHODS: A prospective case-control study was conducted for which data were collected between November 2015 and April 2016 in four rural district hospitals. The occurrence of SMO with near miss incidence ratios was established, followed by an analysis of the characteristics, clinical outcomes, causes and contributory factors. RESULTS: The SMO incidence ratio was 38.4 per 1000 live births (95% CI 33.4-43.4) and the maternal near-miss incidence ratio was 36 per 1000 live births (95% CI 31.1-40.9). The leading causes of SMO were postpartum haemorrhage (23.4%), uterine rupture (22.9%), abortion related complications (16.8%), malaria (13.6%) and hypertensive disorders (8.9%). The case fatality rate was high for women with hypertensive disorders (10.5%; CI 3.3-24.3) and severe postpartum haemorrhage (8%; CI 0.5-15.5). Stillbirth (OR = 181.7; CI 43.5-757.9) and length of stay at the hospital (OR = 7.9; CI 4.5-13.8) were strongly associated with severe outcomes. CONCLUSIONS: Despite the use of life saving interventions, SMO are frequent. Mortality index was found to be low at the level of district hospitals. SMO were associated with long stay at the hospital and stillbirth. There is a need for improvement of quality of care, referral practices and certain types of infrastructure, especially blood banks, which would ensure truly comprehensive emergency obstetric care and reduce the occurrence of SMO. PMID- 29178886 TI - Physical examination in undergraduate medical education in the field of general practice - a scoping review. AB - BACKGROUND: Physical examination (PE) is an essential clinical skill and a central part of a physician's daily activity. Teaching of PE has been integrated into medical school by many clinical disciplines with respective specific examination procedures. For instance, PE teaching in general practice may include a full-body examination approach. Studies show that PE-skills of medical students often need enhancement. The aim of this article was to scope the literature regarding the teaching and research of PE within general practice during undergraduate medical education. We evaluated a wide breadth of literature relating to the content, study design, country of research institution and year of publication. METHODS: Literature search in Medline along the PRISMA-P protocol was performed by search syntax ("physical examination" AND "medical education" AND "undergraduate" AND general practice) considering Medline MeSH (Medical Subject Heading)-Terms and Medline search term tree structure. Independent title, abstract and full-text screening with defined inclusion and exclusion criteria was performed. Full texts were analyzed by publication year, country of origin, study design and content (by categorizing articles along their main topic according to qualitative content analysis of Mayring). RESULTS: One-hundred seven articles were included. The annual number of publications ranged from 4 to 14 and had a slightly rising trend since 2000. Nearly half of the publications originated from the United States (n = 54), 33 from Canada and the United Kingdom. Overall, intervention studies represented the largest group (n = 60, including uncontrolled and controlled studies, randomized and non-randomized), followed by cross-sectional studies (n = 29). The 117 studies could be assigned to five categories "teaching methods (n = 53)", "teaching quality (n = 33)", "performance evaluation and examination formats (n=19)", "students' views (n = 8)" and "patients' and standardized patients' views (n=4)". CONCLUSIONS: The present work shows a wide spectrum of teaching and research activities and a certain level of evidence for the effectiveness of individual teaching methods. It can be used as orientation and impulse generator for the further development of medical education in the field of PE. PMID- 29178887 TI - A multiscale modeling study of particle size effects on the tissue penetration efficacy of drug-delivery nanoparticles. AB - BACKGROUND: Particle size is a key parameter for drug-delivery nanoparticle design. It is believed that the size of a nanoparticle may have important effects on its ability to overcome the transport barriers in biological tissues. Nonetheless, such effects remain poorly understood. Using a multiscale model, this work investigates particle size effects on the tissue distribution and penetration efficacy of drug-delivery nanoparticles. RESULTS: We have developed a multiscale spatiotemporal model of nanoparticle transport in biological tissues. The model implements a time-adaptive Brownian Dynamics algorithm that links microscale particle-cell interactions and adhesion dynamics to tissue-scale particle dispersion and penetration. The model accounts for the advection, diffusion, and cellular uptakes of particles. Using the model, we have analyzed how particle size affects the intra-tissue dispersion and penetration of drug delivery nanoparticles. We focused on two published experimental works that investigated particle size effects in in vitro and in vivo tissue conditions. By analyzing experimental data reported in these two studies, we show that particle size effects may appear pronounced in an in vitro cell-free tissue system, such as collagen matrix. In an in vivo tissue system, the effects of particle size could be relatively modest. We provide a detailed analysis on how particle-cell interactions may determine distribution and penetration of nanoparticles in a biological tissue. CONCLUSION: Our work suggests that the size of a nanoparticle may play a less significant role in its ability to overcome the intra-tissue transport barriers. We show that experiments involving cell-free tissue systems may yield misleading observations of particle size effects due to the absence of advective transport and particle-cell interactions. PMID- 29178888 TI - Anaemia is an essential complication of ANCA-associated renal vasculitis: a single center cohort study. AB - BACKGROUND: Anaemia is a common complication of patients with antineutrophil cytoplasmic antibody (ANCA)-associated renal vasculitis. Nevertheless, the cause and degree of such cases of anaemia have not been elucidated in detail. We aimed to investigate the prevalence, cause, pathogenesis of anaemia and the impact of anaemia on prognosis in patients with ANCA-associated renal vasculitis. METHODS: We identified 45 patients with ANCA-associated renal vasculitis that were clinically and/or histologically diagnosed and treated from 2003 to 2014 at University of Tsukuba Hospital. The relationships between anaemia and various clinicopathological findings were evaluated. RESULTS: At the time of diagnosis of ANCA-associated renal vasculitis, all patients showed anaemia, with a mean haemoglobin level of 7.5 +/- 1.3 g/dL. Renal anaemia was diagnosed in 92% of patients, anaemia of chronic disease (ACD) in 56%, and anaemia due to hemorrhage in 20%. Next, the patients were divided into two groups according to anaemia severity: minimum haemoglobin (min Hb) < 7.5 (n = 24) and min Hb >= 7.5 (n = 21). A comparison of baseline characteristics showed that serum albumin, maximum serum creatinine, minimum estimated glomerular filtration rate (eGFR), serum cystatin C, and the area of tubulointerstitial damage were significantly different between the haemoglobin groups (p < 0.05). No significant intergroup differences were observed in iron-related or inflammation-related data. With regard to the relationship between anaemia severity and prognosis, patients in the min Hb < 7.5 group tended to have a lower eGFR. Anaemia severity was associated with markedly lower survival (Log-rank test, p = 0.03). CONCLUSIONS: In this cohort of patients with ANCA-associated renal vasculitis, all subjects exhibited anaemia. In regard to the cause and pathogenesis, the most prevalent form of anaemia was renal anaemia, not ACD, and a potential reason for the high prevalence of anaemia in our cohort may have been the interaction between renal anaemia and ACD. Moreover, anaemia severity was significantly associated with the degree of renal dysfunction and life prognosis. PMID- 29178889 TI - Lookism hurts: appearance discrimination and self-rated health in South Korea. AB - BACKGROUND: Despite a growing body of evidence suggesting that discrimination harms health, the association between appearance discrimination and health has been understudied. Our study investigated the association between perceived appearance discrimination and self-rated health among emerging adults using a nationally representative cohort study in South Korea. METHODS: We analyzed the 2nd-10th (2005-2013) waves of cohort data from the Korean Education Employment Panel (KEEP). KEEP consists of two groups of individuals who were 15 (group I) and 18 (group II) years old at the 1st wave of the survey (2004) and were followed annually. Appearance discrimination was assessed at baseline (19 years old: 5th wave for group I, 2nd wave for group II) and at follow-up (24 years old: 10th wave for group I, 7th wave for group II). Responses of appearance discrimination at the two-time points were classified into four groups: 1) never (no discrimination at both baseline and follow-up); 2) repeated (discrimination at both baseline and follow-up); 3) incident (discrimination only at follow-up); and 4) in error (discrimination only at baseline). Multivariate logistic regression was applied to examine the association between reporting patterns of appearance discrimination and poor self-rated health, adjusting for potential confounders. RESULTS: Compared to those who did not experience appearance discrimination, 'repeated' (OR: 3.70; 95% CI: 2.19-6.27) and 'incident' (OR: 3.10; 95% CI: 1.99-4.83) groups had a higher odds ratio of poor self-rated health after adjusting for potential confounders including respondents' body mass index change and baseline self-rated health. However, no significant association was observed among those who reported appearance discrimination 'in error'. CONCLUSIONS: These results suggest that perceived appearance discrimination is associated with the health of Korean emerging adults considering participants' reporting patterns of appearance discrimination. PMID- 29178891 TI - Rationale and design for SHAREHD: a quality improvement collaborative to scale up Shared Haemodialysis Care for patients on centre based haemodialysis. AB - BACKGROUND: The study objective is to assess the effectiveness and economic impact of a structured programme to support patient involvement in centre-based haemodialysis and to understand what works for whom in what circumstances and why. It implements a program of Shared Haemodialysis Care (SHC) that aims to improve experience and outcomes for those who are treated with centre-based haemodialysis, and give more patients the confidence to dialyse independently both at centres and at home. METHODS/DESIGN: The 24 month mixed methods cohort evaluation of 600 prevalent centre based HD patients is nested within a 30 month quality improvement program that aims to scale up SHC at 12 dialysis centres across England. SHC describes an intervention where patients who receive centre based haemodialysis are given the opportunity to learn, engage with and undertake tasks associated with their treatment. Following a 6-month set up period, a phased implementation programme is initiated across 12 dialysis units using a randomised stepped wedge design with 6 centres participating in each of 2 steps, each lasting 6 months. The intervention utilises quality improvement methodologies involving rapid tests of change to determine the most appropriate mechanisms for implementation in the context of a learning collaborative. Running parallel with the stepped wedge intervention is a mixed methods cohort evaluation that employs patient questionnaires and interviews, and will link with routinely collected data at the end of the study period. The primary outcome measure is the number of patients performing at least 5 dialysis-related tasks collected using 3 monthly questionnaires. Secondary outcomes measures include: the number of people choosing to perform home haemodialysis or dialyse independently in-centre by the end of the study period; end-user recommendation; home dialysis establishment delay; staff impact and confidence; hospitalisation; infection and health economics. DISCUSSION: The results from this study will provide evidence of impact of SHC, barriers to patient and centre level adoption and inform development of future interventions to support its implementation.

PMID- 29178890 TI - Cytokine and autoantibody clusters interaction in systemic lupus erythematosus. AB - BACKGROUND: Evidence supports the existence of different subphenotypes in systemic lupus erythematosus (SLE) and the pivotal role of cytokines and autoantibodies, which interact in a highly complex network. Thus, understanding how these complex nonlinear processes are connected and observed in real-life settings is a major challenge. Cluster approaches may assist in the identification of these subphenotypes, which represent such a phenomenon, and may contribute to the development of personalized medicine. Therefore, the relationship between autoantibody and cytokine clusters in SLE was analyzed. METHODS: This was an exploratory study in which 67 consecutive women with established SLE were assessed. Clinical characteristics including disease activity, a 14-autoantibody profile, and a panel of 15 serum cytokines were measured simultaneously. Mixed-cluster methodology and bivariate analyses were used to define autoantibody and cytokine clusters and to identify associations between them and related variables. RESULTS: First, three clusters of autoantibodies were defined: (1) neutral, (2) antiphospholipid antibodies (APLA) dominant, and (3) anti-dsDNA/ENA-dominant. Second, eight cytokines showed levels above the threshold thus making possible to find 4 clusters: (1) neutral, (2) chemotactic, (3) G-CSF dominant, and (4) IFNalpha/Pro-inflammatory. Furthermore, the disease activity was associated with cytokine clusters, which, in turn, were associated with autoantibody clusters. Finally, when all biomarkers were included, three clusters were found: (1) neutral, (2) chemotactic/APLA, and (3) IFN/dsDNA, which were also associated with disease activity. CONCLUSION: These results support the existence of three SLE cytokine-autoantibody driven subphenotypes. They encourage the practice of personalized medicine, and support proof-of-concept studies. PMID- 29178892 TI - Knobloch syndrome associated with Polymicrogyria and early onset of retinal detachment: two case reports. AB - BACKGROUND: Knobloch Syndrome (KS) is a rare congenital syndrome characterized by occipital skull defects and vitreoretinal degeneration. Retinal detachment (RD) often occurs at the end of the first decade of life or later. Aside from occipital skull defects, central nervous system abnormalities are uncommon. CASE PRESENTATIONS: We report on two siblings with KS. The first, a seven month old male, presented with nystagmus and was found to have a serous RD and a tessellated retinal appearance. His sister had a history of multiple visual abnormalities and had a similar retinal appearance although no signs of RD, but retina staphylomas. Genetic testing performed on both siblings showed a mutation in COL18A1, diagnostic of KS. MRI of both siblings demonstrated polymicrogyria but did not show occipital defects. CONCLUSIONS: Although several families with KS have been described previously, our case is noteworthy for several reasons. The RD observed in our first patient occurred at an early age, and we find evidence of only one patient with KS who had an RD identified at an earlier age. The findings of polymicrogyria are not characteristic of KS, and we found only a few previous reports of this association. Additionally, we review potential treatment options for this condition. PMID- 29178893 TI - 3D whole-heart phase sensitive inversion recovery CMR for simultaneous black blood late gadolinium enhancement and bright-blood coronary CMR angiography. AB - BACKGROUND: Phase sensitive inversion recovery (PSIR) applied to late gadolinium enhancement (LGE) imaging is widely used in clinical practice. However, conventional 2D PSIR LGE sequences provide sub-optimal contrast between scar tissue and blood pool, rendering the detection of subendocardial infarcts and scar segmentation challenging. Furthermore, the acquisition of a low flip angle reference image doubles the acquisition time without providing any additional diagnostic information. The purpose of this study was to develop and test a novel 3D whole-heart PSIR-like framework, named BOOST, enabling simultaneous black blood LGE assessment and bright-blood visualization of cardiac anatomy. METHODS: The proposed approach alternates the acquisition of a 3D volume preceded by a T2 prepared Inversion Recovery (T2Prep-IR) module (magnitude image) with the acquisition of a T2-prepared 3D volume (reference image). The two volumes (T2Prep IR BOOST and bright-blood T2Prep BOOST) are combined in a PSIR-like reconstruction to obtain a complementary 3D black-blood volume for LGE assessment (PSIR BOOST). The black-blood PSIR BOOST and the bright-blood T2Prep BOOST datasets were compared to conventional clinical sequences for scar detection and coronary CMR angiography (CMRA) in 18 patients with a spectrum of cardiovascular disease (CVD). RESULTS: Datasets from 12 patients were quantitatively analysed. The black-blood PSIR BOOST dataset provided statistically improved contrast to noise ratio (CNR) between blood and scar when compared to a clinical 2D PSIR sequence (15.8 +/- 3.3 and 4.1 +/- 5.6, respectively). Overall agreement in LGE depiction was found between 3D black-blood PSIR BOOST and clinical 2D PSIR acquisitions, with 11/12 PSIR BOOST datasets considered diagnostic. The bright blood T2Prep BOOST dataset provided high quality depiction of the proximal coronary segments, with improvement of visual score when compared to a clinical CMRA sequence. Acquisition time of BOOST (~10 min), providing information on both LGE uptake and heart anatomy, was comparable to that of a clinical single CMRA sequence. CONCLUSIONS: The feasibility of BOOST for simultaneous black-blood LGE assessment and bright-blood coronary angiography was successfully tested in patients with cardiovascular disease. The framework enables free-breathing multi contrast whole-heart acquisitions with 100% scan efficiency and predictable scan time. Complementary information on 3D LGE and heart anatomy are obtained reducing examination time. PMID- 29178894 TI - Changes in overall ventricular myocardial architecture in the setting of a porcine animal model of right ventricular dilation. AB - BACKGROUND: Chronic pulmonary regurgitation often leads to myocardial dysfunction and heart failure. It is not fully known why secondary hypertrophy cannot fully protect against the increase in wall stress brought about by the increased end diastolic volume in ventricular dilation. It has been assumed that mural architecture is not deranged in this situation, but we hypothesised that there might be a change in the pattern of orientation of the aggregations of cardiomyocytes, which would contribute to contractile impairment. METHODS: We created pulmonary valvular regurgitation by open chest, surgical suturing of its leaflets in seven piglets, performing sham operations in seven control animals. Using cardiovascular magnetic resonance imaging after 12 weeks of recovery, we demonstrated significantly increased right ventricular volumes in the test group. After sacrifice, diffusion tensor imaging of their hearts permitted measurement of the orientation of the cardiomyocytes. RESULTS: The helical angles in the right ventricle approached a more circumferential orientation in the setting of right ventricular RV dilation (p = 0.007), with an increased proportion of surface-parallel cardiomyocytes. In contrast, this proportion decreased in the left ventricle. Also in the left ventricle a higher proportion of E3 angles with a value around zero was found, and conversely a lower proportion of angles was found with a numerical higher value. In the dilated right ventricle the proportion of E3 angles around -90 degrees is increased, while the proportion around 90 degrees is decreased. CONCLUSION: Contrary to traditional views, there is a change in the orientation of both the left ventricular and right ventricular cardiomyocytes subsequent to right ventricular dilation. This will change their direction of contraction and hinder the achievement of normalisation of cardiomyocytic strain, affecting overall contractility. We suggest that the aetiology of the cardiac failure induced by right vetricular dilation may be partly explained by morphological changes in the myocardium itself. PMID- 29178895 TI - Informed, advance refusals of treatment by people with severe mental illness in a randomised controlled trial of joint crisis plans: demand, content and correlates. AB - BACKGROUND: In the UK, crisis planning for mental health care should acknowledge the right to make an informed advance treatment refusal under the Mental Capacity Act 2005. Our aims were to estimate the demand for such treatment refusals within a sample of service users who had had a recent hospital admission for psychosis or bipolar disorder, and to examine the relationship between refusals, and service user characteristics. METHODS: To identify refusals we conducted content analysis of Joint Crisis Plans, which are plans formulated by service users and their clinical team with involvement from an external facilitator, and routine care plans in sub-samples from a multi-centre randomised controlled trial of Joint Crisis Plans (plus routine mental health care) versus routine care alone (CRIMSON) in England. Factors hypothesised to be associated with refusals were identified using the trial data collected through baseline interviews of service users and clinicians and collection of routine clinical data. RESULTS: Ninety nine of 221 (45%) of the Joint Crisis Plans contained a treatment refusal compared to 10 of 424 (2.4%) baseline routine care plans. No Joint Crisis Plans recorded disagreement with refusals on the part of clinicians. Among those with completed Joint Crisis Plans, adjusted analyses indicated a significant association between treatment refusals and perceived coercion at baseline (odds ratio = 1.21, 95% CI 1.02-1.43), but not with baseline working alliance or a past history of involuntary admission. CONCLUSIONS: We demonstrated significant demand for written treatment refusals in line with the Mental Capacity Act 2005, which had not previously been elicited by the process of treatment planning. Future treatment/crisis plans should incorporate the opportunity for service users to record a treatment refusal during the drafting of such plans. TRIAL REGISTRATION: ISRCTN11501328 Registered 13th March 2008. PMID- 29178896 TI - Estimating the value of point-of-care HPV testing in three low- and middle-income countries: a modeling study. AB - BACKGROUND: Where resources are available, the World Health Organization recommends cervical cancer screening with human papillomavirus (HPV) DNA testing and subsequent treatment of HPV-positive women with timely cryotherapy. Newer technologies may facilitate a same-day screen-and-treat approach, but these testing systems are generally too expensive for widespread use in low-resource settings. METHODS: To assess the value of a hypothetical point-of-care HPV test, we used a mathematical simulation model of the natural history of HPV and data from the START-UP multi-site demonstration project to estimate the health benefits and costs associated with a shift from a 2-visit approach (requiring a return visit for treatment) to 1-visit HPV testing (i.e., screen-and-treat). We estimated the incremental net monetary benefit (INMB), which represents the maximum additional lifetime cost per woman that could be incurred for a new point of-care HPV test to be cost-effective, depending on expected loss to follow-up between visits (LTFU) in a given setting. RESULTS: For screening three times in a lifetime at 100% coverage of the target population, when LTFU was 10%, the INMB of the 1-visit relative to the 2-visit approach was I$13 in India, I$36 in Nicaragua, and I$17 in Uganda. If LTFU was 30% or greater, the INMB values for the 1-visit approach in all countries was equivalent to or exceeded total lifetime costs associated with screening three times in a lifetime. At a LTFU level of 70%, the INMB of the 1-visit approach was I$127 in India, I$399 in Nicaragua, and I$121 in Uganda. CONCLUSIONS: These findings indicate that point of-care technology for cervical cancer screening may be worthy of high investment if linkage to treatment can be assured, particularly in settings where LTFU is high. PMID- 29178897 TI - MicroRNA expression changes in association with changes in interleukin 1beta/interleukin10 ratios produced by monocytes in autism spectrum disorders: their association with neuropsychiatric symptoms and comorbid conditions (observational study). AB - BACKGROUND: MicroRNAs (miRNAs) play a major role in regulating immune responses at post-transcriptional levels. Previously, we have reported fluctuating interlukine-1beta (IL-1beta)/IL-10 ratios produced by peripheral blood monocytes (PBMo) in some patients with autism spectrum disorders (ASD). This study examined whether changes in miRNA expression by PBMo are associated with changes in IL 1beta/IL-10 ratios and how such changes are associated with ASD clinical features. METHODS: miRNA expression by purified PBMo from ASD subjects (N = 69) and non-ASD controls (N = 27) were determined by high-throughput sequencing. Cytokine production by PBMo in responses to stimuli of innate immunity, and behavioral symptoms [assessed by aberrant behavioral checklist (ABC)] were also evaluated at the same time of sample obtainment. RESULTS: As a whole, there was no difference in miRNA expression between ASD and control non-ASD PBMo. However, when ASD cells were subdivided into 3 groups with high, normal, or low IL 1beta/IL-10 ratios as defined in the "Results" section, in comparison with the data obtained from non-ASD controls, we observed marked changes in miRNA expression. Namely, over 3-fold changes in expression of miR-181a, miR-93, miR 223, miR-342, and miR-1248 were observed in ASD PBMo with high or low IL-1beta/IL 10 ratios, but not in ASD PBMo with normal ratios. These miRNAs that had altered in expression are those closely associated with the regulation of key signaling pathways. With changes in IL-1beta/IL-10 ratios, we also observed changes in the production of cytokines (IL-6, TNF-alpha, and TGF-beta) other than IL-1beta/IL-10 by ASD PBMo. The association between behavioral symptoms and cytokine levels was different when ASD cells exhibit high/low IL-1beta/IL-10 ratios vs. when ASD cells exhibited normal ratios. Non-IgE-mediated food allergy was also observed at higher frequency in ASD subjects with high/low IL-1beta/IL-10 ratios than with normal ratios. CONCLUSIONS: Changes in cytokine profiles and miRNA expression by PBMo appear to be associated with changes in ASD behavioral symptoms. miRNAs that are altered in expression in ASD PBMo with high/low IL-1beta/IL-10 ratios are those associated with inflammatory responses. Changes in IL-1beta/IL-10 ratios along with changes in miRNA expression may serve as biomarkers for immune mediated inflammation in ASD. PMID- 29178898 TI - The wearable cardioverter defibrillator as a bridge to reimplantation in patients with ICD or CRT-D-related infections. AB - BACKGROUND: The approach to treat device infection in patients with implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D) is a challenging procedure. Optimal treatment is complete extraction of the infected device. To protect these patients from sudden cardiac arrest while waiting for reimplantation and to avoid recurrent infection, a wearable cardioverter defibrillator (WCD) seems to be a valuable solution. Therefore, we investigated the management and outcome of patients with ICD or CRT D infections using the WCD as a bridge to re-implantation after lead extraction procedures. METHODS: We conducted a retrospective study on consecutive patients who underwent ICD or CRT-D removal due to device-related local or systemic infections. All patients were prescribed a WCD at our center between 01/2012 and 10/2015. All patients returned to our outpatient clinic for regular ICD or CRT-D monitoring initially 1 and 3 months after reimplantation followed by 6-months intervals. RESULTS: Twenty-one patients (mean age 65.0 +/- 8.0 years, male 76.2%) were included in the study. Complete lead extraction was achieved in all patients. While waiting for reimplantation one patient experienced a symptomatic episode of sustained ventricular tachycardia. This episode was converted successfully into sinus rhythm by a single 150 J shock. Mean follow-up time 392 +/- 206 days, showing survival rate of 100% and freedom from reinfection in all patients. CONCLUSION: The WCD seems to be a valuable bridging option for patients with ICD or CRT-D infections, showing no recurrent device infection. PMID- 29178899 TI - Smoking and alcohol cessation intervention in relation to radical cystectomy: a qualitative study of cancer patients' experiences. AB - BACKGROUND: Despite smoking and risky alcohol drinking being modifiable risk factors for cancer as well as postoperative complications, perioperative cessation counselling is often ignored. Little is known about how cancer patients experience smoking and alcohol interventions in relation to surgery. Therefore the aim of this study was to explore how bladder cancer patients experience a perioperative smoking and alcohol cessation intervention in relation to radical cystectomy. METHODS: A qualitative study was conducted in two urology out-patient clinics. We conducted semi-structured in-depth interviews with 11 purposively sampled persons who had received the smoking and alcohol cessation intervention. The analysis followed the steps contained in the thematic network analysis. RESULTS: Two global themes emerged: "smoking and alcohol cessation was experienced as an integral part of bladder cancer surgery" and "returning to everyday life was a barrier for continued smoking cessation/alcohol reduction". Participants described that during hospitalization their focus shifted to the operation and they did not experience craving to smoke or drink alcohol. Concurrent with improved well-being or experiencing stressful situations, the risk of relapse increased when returning to everyday life. CONCLUSIONS: The smoking and alcohol cessation intervention was well received by the participants. Cancer surgery served as a kind of refuge and was a useful cue for motivating patients to quit smoking and to reconsider the consequences of risky drinking. These results adds to the sparse evidence of what supports smoking and alcohol cessation in relation to bladder cancer patients undergoing major surgery and point to the need to educate healthcare professionals in offering smoking and alcohol cessation interventions in hospitals. The study also provides knowledge about the intervention in the STOP-OP study and will help guide the design of future smoking and alcohol cessation studies aimed at cancer patients undergoing surgery. PMID- 29178900 TI - Social-cognitive determinants of the tick check: a cross-sectional study on self protective behavior in combatting Lyme disease. AB - BACKGROUND: Performing a tick check after visiting nature is considered the most important preventive measure to avoid contracting Lyme disease. Checking the body for ticks after visiting nature is the only measure that can fully guarantee whether one has been bitten by a tick and provides the opportunity to remove the tick as soon as possible, thereby greatly reducing the chance of contracting Lyme disease. However, compliance to performing the tick check is low. In addition, most previous studies on determinants of preventive measures to avoid Lyme disease lack a clear definition and/or operationalization of the term "preventive measures". Those that do distinguish multiple behaviors including the tick check, fail to describe the systematic steps that should be followed in order to perform the tick check effectively. Hence, the purpose of this study was to identify determinants of systematically performing the tick check, based on social cognitive theory. METHODS: A cross-sectional self-administered survey questionnaire was filled out online by 508 respondents (Mage = 51.7, SD = 16.0; 50.2% men; 86.4% daily or weekly nature visitors). Bivariate correlations and multivariate regression analyses were conducted to identify associations between socio-cognitive determinants (i.e. concepts related to humans' intrinsic and extrinsic motivation to perform certain behavior), and the tick check, and between socio-cognitive determinants and proximal goal to do the tick check. RESULTS: The full regression model explained 28% of the variance in doing the tick check. Results showed that performing the tick check was associated with proximal goal (beta = .23, p < 0.01), self-efficacy (beta = .22, p < 0.01), self evaluative outcome expectations (beta = .21, p < 0.01), descriptive norm (beta = .16, p < 0.01), and experience (beta = .13, p < 0.01). CONCLUSIONS: Our study is among the first to examine the determinants of systematic performance of the tick check, using an extended version of social cognitive theory to identify determinants. Based on the results, a number of practical recommendations can be made to promote the performance of the tick check. PMID- 29178901 TI - Bereaved family members' perceptions of the quality of end-of-life care across four types of inpatient care settings. AB - BACKGROUND: The aims of this study were to gain a better understanding of how bereaved family members perceive the quality of EOL care by comparing their satisfaction with quality of end-of-life care across four different settings and by additionally examining the extent to which demographic characteristics and psychological variables (resilience, optimism, grief) explain variation in satisfaction. METHODS: A cross-sectional mail-out survey was conducted of bereaved family members of patients who had died in extended care units (n = 63), intensive care units (n = 30), medical care units (n = 140) and palliative care units (n = 155). 1254 death records were screened and 712 bereaved family caregivers were identified as eligible, of which 558 (who were initially contacted by mail and then followed up by phone) agreed to receive a questionnaire and 388 returned a completed questionnaire (response rate of 70%). Measures included satisfaction with end-of-life care (CANHELP- Canadian Health Care Evaluation Project - family caregiver bereavement version; scores range from 0 = not at all satisfied to 5 = completely satisfied), grief (Texas Revised Inventory of Grief (TRIG)), optimism (Life Orientation Test - Revised) and resilience (The Resilience Scale). ANCOVA and multivariate linear regression were used to analyze the data. RESULTS: Family members experienced significantly lower satisfaction in MCU (mean = 3.69) relative to other settings (means of 3.90 [MCU], 4.14 [ICU], and 4.00 [PCU]; F (3371) = 8.30, p = .000). Statistically significant differences were also observed for CANHELP subscales of "doctor and nurse care", "illness management", "health services" and "communication". The regression model explained 18.9% of the variance in the CANHELP total scale, and between 11.8% and 27.8% of the variance in the subscales. Explained variance in the CANHELP total score was attributable to the setting of care and psychological characteristics of family members (44%), in particular resilience. CONCLUSION: Findings suggest room for improvement across all settings of care, but improving quality in acute care and palliative care should be a priority. Resiliency appears to be an important psychological characteristic in influencing how family members appraise care quality and point to possible sites for targeted intervention. PMID- 29178902 TI - Distinct association between educational attainment and overweight/obesity in unmarried and married women: evidence from a population-based study in Japan. AB - BACKGROUND: Associations between education and obesity have been consistently reported among women in developed countries, but few studies have considered the influence of marital status and husbands' education. This study aimed to examine differences in the association between education and overweight/obesity by marital status and to determine the contribution of husbands' education to overweight/obesity among community-dwelling Japanese women. METHODS: A questionnaire survey was conducted from 2010 to 2011 among residents aged 25-50 years in Japanese metropolitan areas. Of 2145 women who agreed to participate and completed the survey, 582 were unmarried and 1563 were married. Overweight/obesity was defined as body mass index >=25 kg/m2. Multiple logistic regression analysis was conducted to determine whether women's or their husbands' education was associated with overweight/obesity after adjusting for age, work status, and equivalent income. RESULTS: The prevalence of overweight/obesity was 11.9% among unmarried women and 10.3% among married women. Women's own education was significantly associated with overweight/obesity among unmarried women but not among married women. The multivariate-adjusted odds ratio of high school education or lower compared with university education or higher was 3.21 (95% confidence interval: 1.59-6.51) among unmarried women. Among married women, husbands' education was significantly associated with overweight/obesity: women whose husbands' educational attainment was high school or lower had significantly higher odds of overweight/obesity than did those whose husbands had a university education or higher (1.67, 95% confidence interval: 1.10-2.55). Among married women whose educational attainment was college or higher, women whose husbands' educational attainment was high school or lower had a significantly higher risk for overweight/obesity when compared with women whose husbands' educational attainment was college or higher. CONCLUSIONS: Associations between women's own education and overweight/obesity varied by marital status, and husbands' educational level was important for married women's overweight/obesity. These findings indicate that the social influences bound to educational background affect women's overweight/obesity. PMID- 29178903 TI - Development and in vivo validation of tissue-engineered, small-diameter vascular grafts from decellularized aortae of fetal pigs and canine vascular endothelial cells. AB - BACKGROUND: Tissue engineering has emerged as a promising alternative for small diameter vascular grafts. The aim of this study was to determine the feasibility of using decellularized aortae of fetal pigs (DAFPs) to construct tissue engineered, small-diameter vascular grafts and to test the performance and application of DAFPs as vascular tissue-engineered scaffolds in the canine arterial system. METHODS: DAFPs were prepared by continuous enzymatic digestion. Canine vascular endothelial cells (ECs) were seeded onto DAFPs in vitro and then the vascular grafts were cultured in a custom-designed vascular bioreactor system for 7 days of dynamic culture following 3 days of static culture. The grafts were then transplanted into the common carotid artery of the same seven dogs from which ECs had been derived (two grafts were prepared for each dog with one as a backup; therefore, a total of 14 tissue-engineered blood vessels were prepared). At 1, 3, and 6 months post-transplantation, ultrasonography and contrast-enhanced computed tomography (CT) were used to check the patency of the grafts. Additionally, vascular grafts were sampled for histological and electron microscopic examination. RESULTS: Tissue-engineered, small-diameter vascular grafts can be successfully constructed using DAFPs and canine vascular ECs. Ultrasonographic and CT test results confirmed that implanted vascular grafts displayed good patency with no obvious thrombi. Six months after implantation, the grafts had been remodeled and exhibited a similar structure to normal arteries. Immunohistochemical staining showed that cells had evenly infiltrated the tunica media and were identified as muscular fibroblasts. Scanning electron microscopy showed that the graft possessed a complete cell layer, and the internal cells of the graft were confirmed to be ECs by transmission electron microscopy. CONCLUSIONS: Tissue-engineered, small-diameter vascular grafts constructed using DAFPs and canine vascular ECs can be successfully transplanted to replace the canine common carotid artery. This investigation potentially paves the way for solving a problem of considerable clinical need, i.e., the requirement for small-diameter vascular grafts. PMID- 29178904 TI - Nutritional supplements and herbal medicines for women with polycystic ovary syndrome; a systematic review and meta-analysis. AB - BACKGROUND: Polycystic ovary syndrome (PCOS) is a common, reproductive endocrinopathy associated with serious short and long term health risks. Many women with PCOS use ingestible complementary medicines. This systematic review examined the effect on menstrual regulation and adverse effects from randomised controlled trials. METHODS: Randomised controlled trials (RCTs) that compared herbal or nutritional supplements to placebo or active controls in women with PCOS were eligible for inclusion. Electronic databases were searched to July 2017. Study selection and assessment of quality were conducted independently by two review authors. RESULTS: Twenty four studies (1406 women) investigating seven nutritional supplements and four herbal medicines were included. No one study was assessed as having a low risk of bias. Four trials reported on the primary endpoint menstrual regulation. There was no evidence on improved menstrual regularity for calcium plus vitamin D compared to Metformin (RR: 0.66, 95% CI 0.35 to 1.23, p = 0.19), reduced amenorrhoea for Camellia sinensis compared to placebo (RR: 0.17, 95% CI 0.02 to 1.72, p = 0.13) and no difference in the number of menses per month for Cinnamomum sp. against placebo (MD 0.05, 95% CI -0.36 to 1.36, p = 0.26). Adverse effects were investigated in seven studies (164 women). Mild adverse effects were found for Cinnamomum sp. compared to placebo (17 women, RR: 0.36, 95% CI 0.03 to 0.70, p = 0.03). No difference was found for adverse effects between inositol, B complex vitamins, vitamin D, chromium and placebo. Improved reproduction, metabolic hormones and hyperandrogenism was found for inositol and improved cholesterol for omega three fish oils. CONCLUSION: There is no high quality evidence to support the effectiveness of nutritional supplements and herbal medicine for women with PCOS and evidence of safety is lacking. High quality trials of nutritional supplements and herbal medicines examining menstrual regulation and adverse effects in women with PCOS are needed. PMID- 29178905 TI - Diagnostic performance of semi-quantitative and quantitative stress CMR perfusion analysis: a meta-analysis. AB - BACKGROUND: Stress cardiovascular magnetic resonance (CMR) perfusion imaging is a promising modality for the evaluation of coronary artery disease (CAD) due to high spatial resolution and absence of radiation. Semi-quantitative and quantitative analysis of CMR perfusion are based on signal-intensity curves produced during the first-pass of gadolinium contrast. Multiple semi-quantitative and quantitative parameters have been introduced. Diagnostic performance of these parameters varies extensively among studies and standardized protocols are lacking. This study aims to determine the diagnostic accuracy of semi- quantitative and quantitative CMR perfusion parameters, compared to multiple reference standards. METHOD: Pubmed, WebOfScience, and Embase were systematically searched using predefined criteria (3272 articles). A check for duplicates was performed (1967 articles). Eligibility and relevance of the articles was determined by two reviewers using pre-defined criteria. The primary data extraction was performed independently by two researchers with the use of a predefined template. Differences in extracted data were resolved by discussion between the two researchers. The quality of the included studies was assessed using the 'Quality Assessment of Diagnostic Accuracy Studies Tool' (QUADAS-2). True positives, false positives, true negatives, and false negatives were subtracted/calculated from the articles. The principal summary measures used to assess diagnostic accuracy were sensitivity, specificity, andarea under the receiver operating curve (AUC). Data was pooled according to analysis territory, reference standard and perfusion parameter. RESULTS: Twenty-two articles were eligible based on the predefined study eligibility criteria. The pooled diagnostic accuracy for segment-, territory- and patient-based analyses showed good diagnostic performance with sensitivity of 0.88, 0.82, and 0.83, specificity of 0.72, 0.83, and 0.76 and AUC of 0.90, 0.84, and 0.87, respectively. In per territory analysis our results show similar diagnostic accuracy comparing anatomical (AUC 0.86(0.83-0.89)) and functional reference standards (AUC 0.88(0.84-0.90)). Only the per territory analysis sensitivity did not show significant heterogeneity. None of the groups showed signs of publication bias. CONCLUSIONS: The clinical value of semi-quantitative and quantitative CMR perfusion analysis remains uncertain due to extensive inter-study heterogeneity and large differences in CMR perfusion acquisition protocols, reference standards, and methods of assessment of myocardial perfusion parameters. For wide spread implementation, standardization of CMR perfusion techniques is essential. TRIAL REGISTRATION: CRD42016040176 . PMID- 29178906 TI - Femoral nonunion with segmental bone defect treated by distraction osteogenesis with monolateral external fixation. AB - BACKGROUND: Currently, the common treatment for femoral nonunion with large segmental bone defect is difficult and complex. The effective surgical methods are rare, include vascularized bone grafting, Masquelet technique and Ilizarov distraction osteogenesis. The objective of this study is to investigate the outcomes of segmental femoral defects treated with monolateral external fixation using the distraction osteogenesis. METHODS: We retrospectively analyzed patients with femoral nonunion with segmental bone defects (> 6 cm) between January 2010 and January 2014 in our single trauma center. All patients were treated by distraction osteogenesis with monolateral external fixation. All surgeries were performed by the same surgeon. Bone union, duration of distraction osteogenesis in days, time to consolidation in months, external fixation index (EFI), complications, and additional surgical interventions were recorded postoperatively. The modified Application of Methods of Illizarov (ASAMI) criteria were used to evaluate the operative effectiveness. RESULTS: Forty-one patients were enrolled in this study for analysis. The length of the bone defect ranged from 6 to 17 cm. All patients eventually achieved healing, and no patient experienced recurrence of infection or newly developed infection. The average time needed for healing was 13 months. In terms of the incidence of complications, 3 cases axial deviations, 5 cases docking site nonunion, 23 cases pin-tract infection, 14 cases knee joint stiffness or their joint mobility declined, 2 cases osteogenesis insufficient in the distraction area,1 case refracture, and 2 cases loose external fixation pins. In terms of the evaluations of fracture healing and function, 30 patients excellent, 6 patients good, 5 patients fair, and 0 patient poor. In terms of postoperative function evaluations, 21 patients excellent, 9 patients good, 7 patients fair, and 4 patients poor. CONCLUSION: For patients with femoral nonunion with large segmental bone defects, the monolateral external fixation can provide effective stability, improve compliance, and reduce complications. PMID- 29178907 TI - Impact of adenotonsillectomy on pediatric quality of life: review of the literature. AB - Adenotonsillectomy (ADT) is one of the most widely used procedures in the treatment of paediatric recurrent acute tonsillitis (RAT) and obstructive sleep apnoea syndrome (OSAS), both of which have significant repercussions on the patients' quality of life (QoL). The purpose of our review of literature was to highlight the great variety of tools that are currently used to evaluate QoL in children, to examine data available on their efficacy and the feasibility of their use in daily clinical practice, and to determine possible limitations related to an indirect and subjective assessment of QoL in children.Although the use of different parameters makes it difficult to compare the published studies, an analysis of the evidence currently available in the literature suggests that ADT has a generally positive impact on the QoL (especially in case of OSAS). It also highlights the importance of combining tonsillectomy and adenoidectomy in the treatment of OSAS, and documents the comparability of tonsillectomy and tonsillotomy in improving obstructive symptoms. In conclusion, our findings suggest that literature supports that ADT is associated with positive changes in QOL; however further studies using comparable standardised criteria are necessary to confirm the size and duration of this benefit. PMID- 29178909 TI - Functional diversity of home gardens and their agrobiodiversity conservation benefits in Benin, West Africa. AB - BACKGROUND: Understanding the functional diversity of home gardens and their socio-ecological determinants is essential for mainstreaming these agroforestry practices into agrobiodiversity conservation strategies. This paper analyzed functional diversity of home gardens, identified the socio-ecological drivers of functions assigned to them, and assessed the agrobiodiversity benefits of home gardens functions. METHODS: Using data on occurring species in home garden (HG) and functions assigned to each species by the gardeners, the study combined clustering and discriminant canonical analyses to explore the functional diversity of 360 home gardens in Benin, West Africa. Next, multinomial logistic models and chi-square tests were used to analyze the effect of socio-demographic characteristics of gardeners (age, gender, and education level), agro-ecological zones (humid, sub-humid, and semi-arid), and management regime (single and multiple managers) on the possession of a functional type of home gardens. Generalized linear models were used to assess the effect of the functions of home gardens and the determinant factor on their potential in conserving agrobiodiversity. RESULTS: Seven functional groups of home gardens, four with specific functions (food, medicinal, or both food and medicinal) and three with multiple functions (more than two main functions), were found. Women owned most of home gardens with primarily food plant production purpose while men owned most of home gardens with primarily medicinal plant production purposes. Finding also showed that multifunctional home gardens had higher plant species diversity. Specifically, crops and crop wild relatives occurred mainly in home gardens with food function while wild plant species were mostly found in home gardens with mainly medicinal function. CONCLUSIONS: Home gardening is driven by functions beyond food production. These functions are mostly related to direct and extractive values of home gardens. Functions of home gardens were gendered, with women mostly involved in home food gardens, and contribute to maintenance of crops and crop wild relatives while men were mostly home medicinal gardeners and contribute to the maintenance of wild plant species in home gardens. Although multiple functional home gardens were related to higher plant diversity, there was no guarantee for long-term maintenance of plant species in home gardens. PMID- 29178908 TI - Tick-borne pathogens in ticks collected from birds in Taiwan. AB - BACKGROUND: A variety of human diseases transmitted by arthropod vectors, including ticks, are emerging around the globe. Birds are known to be hosts of ticks and can disperse exotic ticks and tick-borne pathogens. In Taiwan, previous studies have focused predominantly on mammals, leaving the role of birds in the maintenance of ticks and dissemination of tick-borne pathogens undetermined. METHODS: Ticks were collected opportunistically when birds were studied from 1995 to 2013. Furthermore, to improve knowledge on the prevalence and mean load of tick infestation on birds in Taiwan, ticks were thoroughly searched for when birds were mist-netted at seven sites between September 2014 and April 2016 in eastern Taiwan. Ticks were identified based on both morphological and molecular information and were screened for potential tick-borne pathogens, including the genera Anaplasma, Babesia, Borrelia, Ehrlichia and Rickettsia. Finally, a list of hard tick species collected from birds in Taiwan was compiled based on past work and the current study. RESULTS: Nineteen ticks (all larvae) were recovered from four of the 3096 unique mist-netted bird individuals, yielding a mean load of 0.006 ticks/individual and an overall prevalence of 0.13%. A total of 139 ticks from birds, comprising 48 larvae, 35 nymphs, 55 adults and one individual of unknown life stage, were collected from 1995 to 2016, and 11 species of four genera were identified, including three newly recorded species (Haemaphysalis wellingtoni, Ixodes columnae and Ixodes turdus). A total of eight tick-borne pathogens were detected, with five species (Borrelia turdi, Anaplasma sp. clone BJ01, Ehrlichia sp. BL157-9, Rickettsia helvetica and Rickettsia monacensis) not previously isolated in Taiwan. Overall, 16 tick species of five genera have been recorded feeding on birds, including nine species first discovered in this study. CONCLUSION: Our study demonstrates the paucity of information on ticks of birds and emphasizes the need for more research on ticks of birds in Taiwan and Southeast Asia. Moreover, some newly recorded ticks and tick-borne pathogens were found only on migratory birds, demonstrating the necessity of further surveillance on these highly mobile species. PMID- 29178910 TI - Effects of dietary supplementation of leaves and whole plant of Andrographis paniculata on rumen fermentation, fatty acid composition and microbiota in goats. AB - BACKGROUND: The nature and amount of dietary medicinal plants are known to influence rumen fermentation and nutrient digestibility in ruminants. Nonetheless, changes in nutrient digestibility and rumen metabolism in response to dietary Andrographis paniculata (AP) in goats are unknown. This study examined the effects of dietary supplementation of leaves and whole plant of AP on nutrient digestibility, rumen fermentation, fatty acids and rumen microbial population in goats. Twenty-four Boer crossbred bucks (4 months old; average body weight of 20.18 +/- 0.19 kg) were randomly assigned to three dietary groups of eight goats each. The dietary treatments included a control diet (Basal diet without additive), basal diet +1.5% (w/w) Andrographis paniculata leaf powder (APL) and basal diet +1.5% (w/w) Andrographis paniculata whole plant powder (APW). The trial lasted 100 d following 14 d of adjustment. RESULTS: The rumen pH and concentration of propionate were greater (P < 0.05) in goats fed the APL and APW diets than those fed the control diet. The concentrations of ammonia nitrogen and acetate were greater (P < 0.05) in the control goats than the APL and APW goats. The digestibilities of crude protein, dry matter, acid detergent fibre and neutral detergent fibre were greater (P < 0.05) in the APL and APW goats compared to the control goats. Dietary APL and APW decreased (P < 0.05) the ruminal concentration of C18:0 and increased (P < 0.05) the ruminal concentration of C18:2n-6 and C18:3n-3. The APL goats had greater (P < 0.05) ruminal concentration of C18:1 trans-11 and CLA cis-9 trans-11 than the APW and control goats. Dietary treatments had no significant effect on the population of protozoa and methanogens in the rumen of goats. The ruminal populations of Ruminococcus albus, Ruminococcus flavefaciens and Fibrobacter succinogenes were greater (P < 0.05) in the APL and APW goats than the control goats. CONCLUSION: Dietary supplementation of leaves and whole plant of Andrographis paniculata can be used to manipulate rumen metabolism for improved nutrient digestibility in goats. PMID- 29178912 TI - Optimization of the prescription isodose line for Gamma Knife radiosurgery using the shot within shot technique. AB - BACKGROUND: This work explores how the choice of prescription isodose line (IDL) affects the dose gradient, target coverage, and treatment time for Gamma Knife radiosurgery when a smaller shot is encompassed within a larger shot at the same stereotactic coordinates (shot within shot technique). METHODS: Beam profiles for the 4, 8, and 16 mm collimator settings were extracted from the treatment planning system and characterized using Gaussian fits. The characterized data were used to create over 10,000 shot within shot configurations by systematically changing collimator weighting and choice of prescription IDL. Each configuration was quantified in terms of the dose gradient, target coverage, and beam-on time. By analyzing these configurations, it was found that there are regions of overlap in target size where a higher prescription IDL provides equivalent dose fall-off to a plan prescribed at the 50% IDL. Furthermore, the data indicate that treatment times within these regions can be reduced by up to 40%. An optimization strategy was devised to realize these gains. The strategy was tested for seven patients treated for 1-4 brain metastases (20 lesions total). RESULTS: For a single collimator setting, the gradient in the axial plane was steepest when prescribed to the 56-63% (4 mm), 62-70% (8 mm), and 77-84% (16 mm) IDL, respectively. Through utilization of the optimization technique, beam-on time was reduced by more than 15% in 16/20 lesions. The volume of normal brain receiving 12 Gy or above also decreased in many cases, and in only one instance increased by more than 0.5 cm3. CONCLUSIONS: This work demonstrates that IDL optimization using the shot within shot technique can reduce treatment times without degrading treatment plan quality. PMID- 29178911 TI - Inhibition of HMGB1 reduces rat spinal cord astrocytic swelling and AQP4 expression after oxygen-glucose deprivation and reoxygenation via TLR4 and NF kappaB signaling in an IL-6-dependent manner. AB - BACKGROUND: Spinal cord astrocyte swelling is an important component to spinal cord edema and is associated with poor functional recovery as well as therapeutic resistance after spinal cord injury (SCI). High mobility group box-1 (HMGB1) is a mediator of inflammatory responses in the central nervous system and plays a critical role after SCI. Given this, we sought to identify both the role and underlying mechanisms of HMGB1 in cellular swelling and aquaporin 4 (AQP4) expression in cultured rat spinal cord astrocytes after oxygen-glucose deprivation/reoxygenation (OGD/R). METHODS: The post-natal day 1-2 Sprague-Dawley rat spinal cord astrocytes were cultured in vitro, and the OGD/R model was induced. We first investigated the effects of OGD/R on spinal cord astrocytic swelling and HMGB1 and AQP4 expression, as well as HMGB1 release. We then studied the effects of HMGB1 inhibition on cellular swelling, HMGB1 and AQP4 expression, and HMGB1 release. The roles of both toll-like receptor 4 (TLR4)/nuclear factor kappa B (NF-kappaB) signaling pathway and interleukin-6 (IL-6) in reducing cellular swelling resulting from HMGB1 inhibition in spinal cord astrocytes after OGD/R were studied. Intergroup data were compared using one-way analysis of variance (ANOVA) followed by Dunnett's test. RESULTS: The OGD/R increased spinal cord astrocytic swelling and HMGB1 and AQP4 expression, as well as HMGB1 release. Inhibition of HMGB1 using either HMGB1 shRNA or ethyl pyruvate resulted in reduced cellular volume, mitochondrial and endoplasmic reticulum swelling, and lysosome number and decreased upregulation of both HMGB1 and AQP4 in spinal cord astrocytes, as well as HMGB1 release. The HMGB1 effects on spinal cord astrocytic swelling and AQP4 upregulation after OGD/R were mediated-at least in part-via activation of TLR4, myeloid differentiation primary response gene 88 (MyD88), and NF-kappaB. These activation effects can be repressed by TLR4 inhibition using CLI 095 or C34, or by NF-kappaB inhibition using BAY 11-7082. Furthermore, either OGD/R or HMGB1 inhibition resulted in changes in IL-6 release. IL-6 was also shown to mediate AQP4 expression in spinal cord astrocytes. CONCLUSIONS: HMGB1 upregulates AQP4 expression and promotes cell swelling in cultured spinal cord astrocytes after OGD/R, which is mediated through HMGB1/TLR4/MyD88/NF-kappaB signaling and in an IL-6-dependent manner. PMID- 29178913 TI - Identification of multiple cancer-associated myositis-specific autoantibodies in idiopathic inflammatory myopathies: a large longitudinal cohort study. AB - BACKGROUND: Cancer is a significant complication contributing to increased mortality in idiopathic inflammatory myopathies (IIMs), and the association between IIMs and cancer has been extensively reported. Myositis-specific autoantibodies (MSAs) can help to stratify patients into more homogeneous groups and may be used as a biomarker for cancer-associated myositis. In this study, we aimed to systematically define the cancer-associated MSAs in IIMs. METHODS: Serum from 627 patients with IIMs was tested for MSAs. The cancer risk with different MSAs was estimated by standardized incidence ratio (SIR). Paraneoplastic manifestation, such as the close temporal relationship between myositis onset and cancer diagnoses in patients with different MSAs, was also evaluated. RESULTS: Compared with the general Chinese population, patients with IIMs and anti transcriptional intermediary factor (TIF1)-gamma antibodies (SIR = 17.28, 95% CI 11.94 to 24.14), anti-nuclear matrix protein (NXP2) antibodies (SIR = 8.14, 95% CI 1.63 to 23.86), or anti-SAE1 antibodies (SIR = 12.92, 95% CI 3.23 to 32.94), or who were MSAs-negative (SIR = 3.99, 95% CI 1.96 to 7.14) faced increased risk of cancer. There was no association between specific MSAs subtypes and certain types of cancer. Paraneoplastic manifestations were observed in the patients carrying anti-TIF1-gamma, as well as other MSAs. There were no prognostic differences among the patients with cancer-associated myositis (CAM) from different MSAs subgroups. However, in comparison to those with cancer unrelated to myositis, CAM had a worse prognosis, with an age-adjusted and sex-adjusted Cox hazard ratio (HR) of 10.8 (95% CI 1.38-84.5, p = 0.02) for all-cause mortality. CONCLUSIONS: Our study demonstrates in what is, to our knowledge, the largest population examined to date, that anti-SAE1, and previously reported anti-TIF1 gamma and anti-NXP2 antibodies, are all associated with an increased risk of cancer in patients with IIMs. Moreover, our data suggest that in some cases, anti HMGCR, anti-Jo-1 and anti-PL-12 antibody production might also be driven by malignancy. This can aid in the etiologic research of paraneoplastic myositis and clinical management. PMID- 29178914 TI - Genetic deletion or pharmacological inhibition of soluble epoxide hydrolase reduces brain damage and attenuates neuroinflammation after intracerebral hemorrhage. AB - BACKGROUND: Inflammatory responses significantly contribute to neuronal damage and poor functional outcomes following intracerebral hemorrhage (ICH). Soluble epoxide hydrolase (sEH) is known to induce neuroinflammatory responses via degradation of anti-inflammatory epoxyeicosatrienoic acids (EET), and sEH is upregulated in response to brain injury. The present study investigated the involvement of sEH in ICH-induced neuroinflammation, brain damage, and functional deficits using a mouse ICH model and microglial cultures. METHODS: ICH was induced by injecting collagenase in both wild-type (WT) C57BL/6 mice and sEH knockout (KO) mice. WT mice were injected intracerebroventricularly with 12-(3 adamantan-1-yl-ureido)-dodecanoic acid (AUDA), a selective sEH inhibitor, 30 min before ICH. Expression of sEH in the hemorrhagic hemisphere was examined by immunofluorescence and Western blot analysis. The effects of genetic deletion or pharmacological inhibition of sEH by AUDA on neuroinflammatory responses, EET degradation, blood-brain barrier (BBB) permeability, histological damage, and functional deficits were evaluated. The anti-inflammatory mechanism of sEH inactivation was investigated in thrombin- or hemin-stimulated cultured microglia. RESULTS: ICH induced an increase in sEH protein levels in the hemorrhagic hemisphere from 3 h to 4 days. sEH was expressed in microglia/macrophages, astrocytes, neurons, and endothelial cells in the perihematomal region. Genetic deletion of sEH significantly attenuated microglia/macrophage activation and expression of inflammatory mediators and reduced EET degradation at 1 and 4 days post-ICH. Deletion of sEH also reduced BBB permeability, matrix metalloproteinase (MMP)-9 activity, neutrophil infiltration, and neuronal damage at 1 and 4 days. Likewise, administration of AUDA attenuated proinflammatory microglia/macrophage activation and EET degradation at 1 day post-ICH. These findings were associated with a reduction in functional deficits and brain damage for up to 28 days. AUDA also ameliorated neuronal death, BBB disruption, MMP-9 activity, and neutrophil infiltration at 1 day. However, neither gene deletion nor pharmacological inhibition of sEH altered the hemorrhage volume following ICH. In primary microglial cultures, genetic deletion or pharmacological inhibition of sEH by AUDA reduced thrombin- and hemin induced microglial activation. Furthermore, AUDA reduced thrombin- and hemin induced P38 MAPK and NF-kappaB activation in BV2 microglia cultures. Ultimately, AUDA attenuated N2A neuronal death that was induced by BV2 microglial conditioned media. CONCLUSIONS: Our results suggest that inhibition of sEH may provide a potential therapy for ICH by suppressing microglia/macrophage-mediated neuroinflammation. PMID- 29178915 TI - Longitudinal wall fractional shortening: an M-mode index based on mitral annular plane systolic excursion (MAPSE) that correlates and predicts left ventricular longitudinal strain (LVLS) in intensive care patients. AB - BACKGROUND: Left ventricular longitudinal strain (LVLS) is a modern measurement for LV function. However, strain measurement is often difficult in critically ill patients. We sought to show LVLS can be estimated using M-mode-derived longitudinal wall fractional shortening (LWFS), which is less dependent on image quality and is easier to perform in critically ill patients. METHODS: Transthoracic echocardiographic records were retrospectively screened and 80 studies suitable for strain and M-mode measurements in the apical 4-chamber view were selected. Longitudinal wall fractional shortening was derived from conventional M-mode (LWFS) and curved anatomical M-mode (CAMMFS). The relationships between LVLS and mitral annular plane systolic excusion (MAPSE) and M-mode-derived fractional shortening were examined using univariate generalized linear model in a training set (n = 50) and was validated in a separate validation set (n = 30). RESULTS: MAPSE, CAMMFS, and LWFS demonstrated very good correlations with LVLS (r = 0.852, 0.875 and 0.909, respectively). LWFS was the best unbiased predictor for LVLS (LVLS = 1.180 x LWFS - 0.737, P < 0.001). Intra- and inter-rater agreement and reliability for LWFS measurement were good. CONCLUSIONS: LVLS can be estimated by LWFS in the critically ill patients. It provides a fast and accurate prediction of LVLS. LWFS is a reproducible and reliable measurement which can be used as a potential index in place of LVLS in the critically ill population. PMID- 29178916 TI - Do hedonic- versus nutrition-based attitudes toward food predict food choices? a cross-sectional study of 6- to 11-year-olds. AB - BACKGROUND: Implicit and explicit attitudes are potential precursors of food choices and combine affective and cognitive components that can vary in their relative dominance. Yet, the affective and cognitive components of attitudes toward food can lead to distinct predisposition toward a food item and potentially to different food choices. In the food domain, the affective component pertains to the hedonic tone of consumption, while the cognitive component encompasses nutritional value or health consequences of food. The present study investigated whether hedonic- versus nutrition-based implicit and/or explicit attitudes toward food predicts children's healthy versus unhealthy food choices. METHODS: A total of 63 children (age range = 6.3-11.5) participated in a 90-min session at 5 pm (i.e., afterschool snack time in France). The children were asked to choose five food items from a buffet featuring five healthy and five unhealthy sweet foods pretested as being highly liked. Children ate what they had chosen. Moreover, their implicit attitudes were assessed with a pairing task in which children were presented with 10 food triplets and asked to choose two food items that "best go together". For each triplet, foods could be paired according to their hedonic or nutritional characteristics. Explicit attitudes were assessed with a task in which children placed each of 48 food items into one of the following categories: "yummy", "yucky" (i.e., hedonic categories), "makes you strong", or "makes you fat" (i.e., nutritional categories). RESULTS: Both implicit and explicit attitudes significantly influenced children's food choices. We observed that children with more hedonic-based implicit or explicit attitudes toward food were more likely to choose healthy food options from the buffet. Conversely, children with both implicit and explicit nutrition-based attitudes chose less healthy foods. CONCLUSIONS: Hedonic-based attitudes toward food seem to drive healthier food choices in children compared with nutrition-based attitudes in this particular eating context. These findings suggest that pleasure from eating might be an ally with regard to healthy eating among children. Additional research is needed to understand the etiology of children's attitudes toward food in order to provide insights on how to shape adequate children's attitudes to guide them toward healthy food choices. PMID- 29178917 TI - The influence of surface EMG-triggered multichannel electrical stimulation on sensomotoric recovery in patients with lumbar disc herniation: study protocol for a randomized controlled trial (RECO). AB - BACKGROUND: Intervertebral disc degeneration is one of the most common reasons for chronic low back pain and sensomotoric deficits, often treated by lumbar sequestrectomy. Nevertheless, the prognostic factors relevant for time and quality of recovery, of the surgical procedure, relative to conservative treatment, remain controversial and require further investigation. Surface electrical stimulation (SES) may be an influential intervention, already showing positive impact on motor and sensory recovery in different patient groups. Since mechanisms of SES still remain unclear, further inquiry is needed. METHODS/DESIGN: This is a prospective, monocentric, randomized, controlled clinical trial. A total of 80 adult patients suffering from a lumbar disc herniation (LDH; 40 treated surgically, 40 conservatively) are allocated in a ratio of 1:1. Patients in the treatment group will receive surface electromyography (EMG)-triggered electrical stimulation for eight weeks, whereas patients in the control group will not obtain any additional treatment. The primary outcome parameter is defined as the cold detection threshold (CDT), determined by quantitative sensory testing (QST), 24 months after intervention. Secondary outcome parameters include the inquiry of sensory nerve function by two point discrimination and QST, the assessment of motor nerve function by manual muscle testing, and validated scales and scores. These include: the Oswestry Disability Index (ODI) and the Core Outcome Measures Index (COMI) assessing the domains pain, back-specific function, work disability, and patient satisfaction; the EQ-5D investigating the patient's generic health status; the painDETECT questionnaire (PD-Q) to identify neuropathic pain components; and the Beck Depression Inventory (BDI) to assess severity of depression. Moreover, neurological status, pain medication usage, and blood samples (CRP, TNFalpha, IL 1beta, IL-6) will be evaluated. Study data generation (study site) and data storage, processing, and statistical analysis are clearly separated. DISCUSSION: The results of the RECO study will detect the effect of EMG-triggered multichannel SES on the improvement of mechanical and thermal sensitivity and the effect on motor recovery and pain, associated with clinical and laboratory parameters. Furthermore, data comparing surgical and conservative treatment can be collected. This will hopefully allow treatment recommendations for patients with LDH accompanied by a sensomotoric deficit. TRIAL REGISTRATION: ISRCTN, ISRCTN12741173 . Registered on 15 January 2017. PMID- 29178918 TI - Health state utilities associated with attributes of weekly injection devices for treatment of type 2 diabetes. AB - BACKGROUND: Glucagon-like peptide-1 (GLP-1) receptor agonists are often recommended as part of combination therapy for type 2 diabetes when oral medication does not result in sufficient glycemic control. Several GLP-1 receptor agonists are available as weekly injections. These medications vary in their injection delivery systems, and these differences could impact quality of life and treatment preference. The purpose of this study was to estimate utilities associated with attributes of injection delivery systems for weekly GLP-1 therapies. METHODS: Participants with type 2 diabetes in the UK valued health states in time trade-off interviews. The health states (drafted based on literature, device instructions for use, and clinician interviews) had identical descriptions of type 2 diabetes, but differed in description of the treatment process. One health state described oral treatment, while six others described oral treatment plus a weekly injection. The injection health states varied in three aspects of the treatment administration process: requirements for reconstituting the medication (i.e., mixing the medication prior to the injection), waiting during medication preparation, and needle handling. Every participant valued all seven health states. RESULTS: A total of 209 participants completed interviews (57.4% male; mean age = 60.4y). The mean utility of the oral treatment health state was 0.89. All injection health states had significantly (p < 0.01) lower utilities ranging from 0.86 to 0.88. Differences among health state utilities suggest that each administration requirement had a small but measureable disutility: -0.004 (reconstitution), -0.004 (needle handling), -0.010 (reconstitution, needle handling), and -0.020 (reconstitution, waiting, needle handling). CONCLUSIONS: Findings suggest it is feasible to use the TTO method to quantify preferences among injection treatment processes. It may be useful to incorporate these utility differences into cost-utility models comparing weekly injectable treatments for patients with type 2 diabetes. PMID- 29178919 TI - Double lung, unlike single lung transplantation might provide a protective effect on mortality and bronchiolitis obliterans syndrome. AB - BACKGROUND: Survival after lung transplantation (LTx) is often limited by bronchiolitis obliterans syndrome (BOS). METHOD: Survey of 278 recipients who underwent LTx. The endpoint used was BOS (BOS grade >= 2), death or Re-lung transplantation (Re-LTx) assessed by competing risk regression analyses. RESULTS: The incidence of BOS grade >= 2 among double LTx (DLTx) recipients was 16 +/- 3% at 5 years, 30 +/- 4% at 10 years, and 37 +/- 5% at 20 years, compared to single LTx (SLTx) recipients whose corresponding incidence of BOS grade >= 2 was 11 +/- 3%, 20 +/- 4%, and 24 +/- 5% at 5, 10, and 20 years, respectively (p > 0. 05). The incidence of BOS grade >= 2 by major indications ranked in descending order: other, PF, CF, COPD, PH and AAT1 (p < 0. 05). The mortality rate by major indication ranked in descending order: COPD, PH, AAT1, PF, Other and CF (p < 0. 05). CONCLUSION: No differences were seen in the incidence of BOS grade >= 2 regarding type of transplant, however, DLTx recipients showed a better chance of survival despite developing BOS compared to SLTx recipients. The highest incidence of BOS was seen among CF, PF, COPD, PH, and AAT1 recipients in descending order, however, CF and PF recipients showed a better chance of survival despite developing BOS compared to COPD, PH, and AAT1 recipients. PMID- 29178920 TI - The gut mycobiome of the Human Microbiome Project healthy cohort. AB - BACKGROUND: Most studies describing the human gut microbiome in healthy and diseased states have emphasized the bacterial component, but the fungal microbiome (i.e., the mycobiome) is beginning to gain recognition as a fundamental part of our microbiome. To date, human gut mycobiome studies have primarily been disease centric or in small cohorts of healthy individuals. To contribute to existing knowledge of the human mycobiome, we investigated the gut mycobiome of the Human Microbiome Project (HMP) cohort by sequencing the Internal Transcribed Spacer 2 (ITS2) region as well as the 18S rRNA gene. RESULTS: Three hundred seventeen HMP stool samples were analyzed by ITS2 sequencing. Fecal fungal diversity was significantly lower in comparison to bacterial diversity. Yeast dominated the samples, comprising eight of the top 15 most abundant genera. Specifically, fungal communities were characterized by a high prevalence of Saccharomyces, Malassezia, and Candida, with S. cerevisiae, M. restricta, and C. albicans operational taxonomic units (OTUs) present in 96.8, 88.3, and 80.8% of samples, respectively. There was a high degree of inter- and intra-volunteer variability in fungal communities. However, S. cerevisiae, M. restricta, and C. albicans OTUs were found in 92.2, 78.3, and 63.6% of volunteers, respectively, in all samples donated over an approximately 1-year period. Metagenomic and 18S rRNA gene sequencing data agreed with ITS2 results; however, ITS2 sequencing provided greater resolution of the relatively low abundance mycobiome constituents. CONCLUSIONS: Compared to bacterial communities, the human gut mycobiome is low in diversity and dominated by yeast including Saccharomyces, Malassezia, and Candida. Both inter- and intra-volunteer variability in the HMP cohort were high, revealing that unlike bacterial communities, an individual's mycobiome is no more similar to itself over time than to another person's. Nonetheless, several fungal species persisted across a majority of samples, evidence that a core gut mycobiome may exist. ITS2 sequencing data provided greater resolution of the mycobiome membership compared to metagenomic and 18S rRNA gene sequencing data, suggesting that it is a more sensitive method for studying the mycobiome of stool samples. PMID- 29178921 TI - Plasmodium falciparum Kelch 13 mutations and treatment response in patients in Hpa-Pun District, Northern Kayin State, Myanmar. AB - BACKGROUND: Artemisinin resistance, linked to polymorphisms in the Kelch gene on chromosome 13 of Plasmodium falciparum (k13), has outpaced containment efforts in South East Asia. For national malaria control programmes in the region, it is important to establish a surveillance system which includes monitoring for k13 polymorphisms associated with the clinical phenotype. METHODS: Between February and December 2013, parasite clearance was assessed in 35 patients with uncomplicated P. falciparum treated with artesunate monotherapy followed by 3-day ACT in an isolated area on the Myanmar-Thai border with relatively low artemisinin drug pressure. Molecular testing for k13 mutations was performed on dry blood spots collected on admission. RESULTS: The proportion of k13 mutations in these patients was 41.7%, and only 5 alleles were detected: C580Y, I205T, M476I, R561H, and F446I. Of these, F446I was the most common, and was associated with a longer parasite clearance half-life (median) 4.1 (min-max 2.3-6.7) hours compared to 2.5 (min-max 1.6-8.7) in wildtype (p = 0.01). The prevalence of k13 mutant parasites was much lower than the proportion of k13 mutants detected 200 km south in a much less remote setting where the prevalence of k13 mutants was 84% with 15 distinct alleles in 2013 of which C580Y predominated. CONCLUSIONS: This study provides evidence of artemisinin resistance in a remote part of eastern Myanmar. The prevalence of k13 mutations as well as allele diversity varies considerably across short distances, presumably because of historical patterns of artemisinin use and population movements. PMID- 29178922 TI - Elevated plasma levels of lysophosphatidic acid and aberrant expression of lysophosphatidic acid receptors in adenomyosis. AB - BACKGROUND: Given the important roles of the receptor-mediated lysophosphatidic acid (LPA) signaling in both reproductive tract function and gynecological cancers, it will be informative to investigate the potential role of LPA in the development of adenomyosis. The objective of this study was to evaluate the levels of LPA in plasma and the expression of six LPA receptors in the endometrial tissue collected from women with and without adenomyosis. METHODS: Plasma and endometrial tissue samples were collected form women with and without adenomyosis. The levels of LPA in plasma were determined by using high performance liquid chromatography electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS). Immunohistochemistry was performed to evaluate the expression of six LPA receptors (LPA1-6) in endometrial tissue samples. The effects of LPA on IL-8 production, VEGF production and cell proliferation in human endometrial stromal cells (ESCs) were also assessed. RESULTS: LPA1 staining was localized to the cytoplasm, membrances of the epithelial cells of the endometrial glands, and there was little staining in the stromal cells. LPA2-5 staining were localized to the nuclei of stromal and glandular cells. Plasma levels of LPA were increased in adenomyosis. LPA1, LPA4 and LPA5 immunoreactivity were significantly higher in the adenomyosis group than in the control group, while LPA2 and LPA3 immunoreactivity were significantly lower in the adenomyosis group than in the control group. LPA6 was undetectable in the endometria. LPA induced the release of IL-8 from ESCs but did not affect cell proliferation and VEGF production. CONCLUSION: These results indicate that elevated plasma levels of LPA and aberrant expression of LPA receptors in the endometria may be associated with the development of adenomyosis. PMID- 29178923 TI - Guided self-determination-young versus standard care in the treatment of young females with type 1 diabetes: study protocol for a multicentre randomized controlled trial. AB - BACKGROUND: Female adolescents with type 1 diabetes mellitus (T1DM) have the most unsatisfactory glycaemic control of all age groups and report higher disease burden, poorer perceived health, and lower quality of life than their male counterparts. Females with T1DM face an excess risk of all-cause mortality compared with men with T1DM. New methods are needed to help and support young females with T1DM to manage their disease. A prerequisite for successful diabetes management is to offer individualized, person-centred care and support the patient's own motivation. Guided self-determination (GSD) is a person-centred reflection and problem-solving method intended to support the patient's own motivation in the daily care of her diabetes and help develop skills to manage difficulties in diabetes self-management. GSD has been shown to improve glycaemic control and decrease psychosocial stress in young women with T1DM. The method has been adapted for adolescents and their parents, termed GSD-young (GSD-Y). The aim of this study was to evaluate whether an intervention with GSD-Y in female adolescents with T1DM leads to improved glycaemic control, self-management, treatment satisfaction, perceived health and quality of life, fewer diabetes related family conflicts, and improved psychosocial self-efficacy. METHODS/DESIGN: This is a parallel-group randomized controlled superiority trial with an allocation ratio of 1:1. One hundred female adolescents with T1DM, 15-20 years of age, and their parents (if < 18 years of age), will be included. The intervention group will receive seven individual GSD-Y education visits over 3 to 6 months. The control group will receive standard care including regular visits to the diabetes clinic. The primary outcome is level of glycaemic control, measured as glycosylated haemoglobin (HbA1c). Secondary outcomes include diabetes self-management, treatment satisfaction, perceived health and quality of life, diabetes-related family conflicts, and psychosocial self-efficacy. Data will be collected before randomization and at 6 and 12 months. DISCUSSION: Poor glycaemic control is common in female adolescents and young adults with T1DM. Long-standing hyperglycaemia increases the risks for severe complications and may also have an adverse impact on the outcome of future pregnancies. In this study, we want to evaluate if the GSD-Y method can be a useful tool in the treatment of female adolescents with T1DM. TRIAL REGISTRATION: Current controlled trials, ISRCTN57528404 . Registered on 18 February 2015. PMID- 29178924 TI - Instruments evaluating the self-directed learning abilities among nursing students and nurses: a systematic review of psychometric properties. AB - BACKGROUND: Modern healthcare institutions are continuously changing, and Self Directed Learning (SDL) abilities are considered a prerequisite for both nursing students and nurses in order to be proactive about these demanding challenges. To date, no systematic reviews of existing instruments aimed at detecting and critically evaluating SDL abilities have been published. Therefore, the aims of this review are: 1) identify the instruments for assessment of SDL abilities among nursing students and nurses; 2) critically evaluate the methodological studies quality; and 3) compare the psychometric properties of the available instruments. METHODS: A psychometric-systematic-review was performed. CDSR, CINAHL, ERIC, MEDLINE, PROSPERO, SCOPUS databases were searched without restrictions in time and setting. All primary studies involving nursing students or nurses, written in English and aimed at validating SDL assessment tools, were included. Studies retrieved were evaluated according to the COnsensus-based Standards for the selection of health Measurement-INstruments (COSMIN) panel. Study inclusion, data extraction and quality assessment were performed by researchers independently. RESULTS: Eleven studies were included and four tools based on Knowles's theory have emerged: 1) the Self-Directed Learning Readiness Scale; 2) the Self-Directed Learning Readiness Scale for Nursing Education; 3) the Self-Rating Scale of Self-Directed Learning, and 4) the Self-Directed Learning Instrument. A few psychometric properties have been considered in each study, from two to four out of the ten required. The quality of the methodologies used was in general, from fair to poor with the exception of one instrument (the Self-Directed-Learning-Instrument). The psychometric proprieties that emerged across the tools were good in general: the Cronbach alpha was from 0.73 to 0.91; structural validities have also reported good indexes both in the explorative and in the confirmative factor analyses. CONCLUSIONS: On the basis of the findings, the Self-Directed-Learning-Instrument can be recommended for the assessment of SDL abilities among nursing students and nurses, given the excellent methodology quality adopted in estimating the psychometric properties. However, rigorous study designs aimed at estimating psychometric properties of tools in wide samples of nursing students and nurses across different stages of professional life, from undergraduate education to professional maturity, in different cultural, educational, and work settings, are strongly recommended. PMID- 29178925 TI - Expediting citation screening using PICo-based title-only screening for identifying studies in scoping searches and rapid reviews. AB - BACKGROUND: Citation screening for scoping searches and rapid review is time consuming and inefficient, often requiring days or sometimes months to complete. We examined the reliability of PICo-based title-only screening using keyword searches based on the PICo elements-Participants, Interventions, and Comparators, but not the Outcomes. METHODS: A convenience sample of 10 datasets, derived from the literature searches of completed systematic reviews, was used to test PICo based title-only screening. Search terms for screening were generated from the inclusion criteria of each review, specifically the PICo elements-Participants, Interventions and Comparators. Synonyms for the PICo terms were sought, including alternatives for clinical conditions, trade names of generic drugs and abbreviations for clinical conditions, interventions and comparators. The MeSH database, Wikipedia, Google searches and online thesauri were used to assist generating terms. Title-only screening was performed by five reviewers independently in Endnote X7 reference management software using OR Boolean operator. Outcome measures were recall of included studies and the reduction in screening effort. Recall is the proportion of included studies retrieved using PICo title-only screening out of the total number of included studies in the original reviews. The percentage reduction in screening effort is the proportion of records not needing screening because the method eliminates them from the screen set. RESULTS: Across the 10 reviews, the reduction in screening effort ranged from 11 to 78% with a median reduction of 53%. In nine systematic reviews, the recall of included studies was 100%. In one review (oxygen therapy), four of five reviewers missed the same included study (median recall 67%). A post hoc analysis was performed on the dataset with the lowest reduction in screening effort (11%), and it was rescreened using only the intervention and comparator keywords and omitting keywords for participants. The reduction in screening effort increased to 57%, and the recall of included studies was maintained (100%). CONCLUSIONS: In this sample of datasets, PICo-based title-only screening was able to expedite citation screening for scoping searches and rapid reviews by reducing the number of citations needed to screen but requires a thorough workup of the potential synonyms and alternative terms. Further research which evaluates the feasibility of this technique with heterogeneous datasets in different fields would be useful to inform the generalisability of this technique.

AB - The aim of this Letter to the Editor was to report some methodological shortcomings in a recently published article. Issues regarding missing values and overfitting are mentioned. First, Complete Case (CC) analysis was used instead of an imputation method. Second, there was a high chance of overfitting and lack of model validation. In conclusion, the results of this study should be interpret with caution and further research is necessary. PMID- 29178927 TI - Why is there still hepatitis C transmission in Australian prisons? A case report. AB - BACKGROUND: The ability to cure hepatitis C viral infection, with specific reference to the prisoner population and the prison environment, will be challenged, even if opiate replacement therapy is concurrently offered, and even if bleach is available. The missing elements, widely available in the community, are a regulated injecting equipment exchange and tattooing parlours. CASE PRESENTATION: We report a case of re-infection of hepatitis C in a prisoner treated with a direct-acting antiviral. What makes this case so remarkable is that it was entirely predictable and preventable. CONCLUSIONS: Hepatitis C infection will continue to test both the strengths and the weaknesses in the relationship between health and corrective services in Australia. Nothing less than full implementation of all harm minimisation modalities will be necessary to eliminate the clinical and public health risks of hepatitis C infection, both in prison and by extension into the general community. PMID- 29178929 TI - Serological prevalence and public health significance of brucellosis on a dairy farm in Namibia from 2011 to 2014. AB - OBJECTIVE: The main objective of this study was to determine the serological prevalence of brucellosis on a dairy farm with no past history of abortions, but where Brucella control measures including test and slaughter and vaccination of heifers at 4-8 months of age was practiced. Secondary data from 2011 to 2014 obtained from the Epidemiology Section of the Directorate of Veterinary Services was used. RESULTS: Mandatory annual brucellosis testing results for mature dairy cows on a dairy farm for the period 2011-2014 were collated and analyzed. Results of a total of 6912 cows were analysed. The data comprised of the year of testing, number of cows tested for Brucella antibodies and the number of cows that tested positive. Serological testing was carried out using the Rose Bengal Test (RBT) as a screening test and the Complement Fixation Test as a confirmatory test for results that tested positive on the RBPT. Over the 4-year period, one dairy cow tested positive for Brucella antibodies in 2013 giving an apparent prevalence of 0.05% and an overall prevalence of 0.01%. When apparent prevalence was adjusted for RBPT test specificity and sensitivity of 71 and 78% respectively, true prevalence was determined to be zero. PMID- 29178928 TI - MicroRNA-133 overexpression promotes the therapeutic efficacy of mesenchymal stem cells on acute myocardial infarction. AB - BACKGROUND: Our study aim was to evaluate the therapeutic efficacy and mechanisms of miR-133-overexpressing mesenchymal stem cells (MSCs) on acute myocardial infarction. METHODS: Rat MSCs were isolated and purified by whole bone marrow adherent culturing. After transfection with the agomir or antagomir of miR-133, MSCs were collected for assay of cell vitality, apoptosis, and cell cycle progression. At the same time, exosomes were isolated from the supernatant to analyze the paracrine miR-133. For in-vivo studies, constitutive activation of miR-133 in MSCs was achieved by lentivirus-mediated miR-133 overexpression. A rat myocardial infarction model was created by ligating the left anterior descending coronary artery, while control MSCs (vector-MSCs) or miR-133-overexpressed MSCs (miR-133-MSCs) were injected into the zone around the myocardial infarction. Subsequently, myocardial function was evaluated by echocardiography on days 7 and 28 post infarction. Finally the infarcted hearts were collected on days 7 and 28 for myocardial infarct size measurement and detection of snail 1 expression. RESULTS: Hypoxia-induced apoptosis of MSCs obviously reduced, along with enhanced expression of total poly ADP-ribose polymerase protein, after miR-133 agomir transfection, while the apoptosis rate increased in MSCs transfected with miR-133 antagomir. However, no change in cell viability and cell-cycle distribution was observed in control, miR-133-overexpressed, and miR-133-interfered MSCs. Importantly, rats transplanted with miR-133-MSCs displayed more improved cardiac function after acute myocardial infarction, compared with those that received vector-MSC injection. Further studies indicated that cardiac expression of snail 1 was significantly repressed by adjacent miR-133-overexpressing MSCs, and both the inflammatory level and the infarct size decreased in miR-133-MSC-injected rat hearts. CONCLUSIONS: miR-133-MSCs obviously improved cardiac function in a rat model of myocardial infarction. Transplantation of miR-133-overexpressing MSCs provides an effective strategy for cardiac repair and modulation of cardiac related diseases. PMID- 29178930 TI - An Msh3 ATPase domain mutation has no effect on MMR function. AB - OBJECTIVE: To demonstrate that the Msh3 ATPase domain is required for DNA mismatch repair and tumor suppression in a murine model. RESULTS: The DNA mismatch repair proteins are members of the ABC family of ATPases. ATP binding and hydrolysis regulates their mismatch repair function. In the current study, a mouse model was generated harboring a glycine to aspartic acid residue change in the Walker A motif of the ATPase domain of Msh3. Impaired ATP mediated release of the Msh2-Msh3 GD/GD complex from it's DNA substrate in vitro confirmed the presence of an ATPase defect. However, the mismatch repair function of the protein was not significantly affected. Therefore, mutation of a critical residue within the ATPase domain of Msh3 did not preclude mismatch repair at the genomic sequences tested. Indicating that Msh3 mediated mismatch function is retained the absence of a functional ATPase domain. PMID- 29178931 TI - Anatomy of the sacroiliac joints in children and adolescents by computed tomography. AB - BACKGROUND: Diagnosing sacroiliitis by magnetic resonance imaging (MRI) in children/adolescents can be difficult due to the growth-related changes. This study analyzed the normal osseous anatomy of the sacroiliac joints (SIJ) in a juvenile population using computed tomography (CT). METHODS: The anatomy of the SIJ was retrospectively analyzed in 124 trauma patients aged 9 months - <18 years by CT, based on 2 mm slices in axial, semi-axial and semi-coronal planes. The following anatomical features were recorded: intersegmental fusion of the sacral vertebral segments 1-3 (S1-S3), ossified nuclei (antero-superior at S1, lateral to the intervertebral spaces and lateral to S1 and S2) and joint facet defects larger than 3 mm. RESULTS: Fusion of S1/S2 started at the age of 6 years and was complete after the age of 13 years in most girls and after the age of 14 years in most boys. Fusion of S2/S3 started at the age of 9 years, but could remain incomplete up to 18 years in both genders. Ossified nuclei antero-lateral at S1 and/or in the joint space were observed until the age of 18 years and occurred in 77% of individuals >=13 years with intraarticular localization in 64% of girls and 60% of boys. Joint facet defects >3 mm occurred in 21 children/adolescents (17%) located to both the iliac and sacral joint facets. CONCLUSIONS: Normal osseous SIJ structures in children and adolescents vary considerably. Attention to these normal anatomical structures during growth may help to avoid false positive findings by MRI. PMID- 29178932 TI - Herbst appliance with skeletal anchorage versus dental anchorage in adolescents with Class II malocclusion: study protocol for a randomised controlled trial. AB - BACKGROUND: The Herbst appliance is an orthodontic appliance that is used for the correction of class II malocclusion with skeletal discrepancies. Research has shown that this is effective. However, a potential harm is excessive protrusion of the lower front teeth. This is associated with gingival recession, loss of tooth support, and root resorption. This trial evaluates a method of reducing this problem. METHODS/DESIGN: The study is a single-center, randomised, assessor blinded, superiority clinical trial with parallel 1:1 allocation. Male and female young people (10-14 years old) with prominent front teeth (class II, division 1) will be treated in one orthodontic clinic. Group 1 will be treated with the conventional Herbst appliance with dental anchorage and group 2 with the Herbst appliance with indirect skeletal anchorage for 12 months. The primary objective will be to compare the proclination of the lower incisors between the Herbst appliance with dental anchorage and skeletal anchorage. Secondary objectives will be to evaluate the changes occurring between the groups in the mandible, maxilla, lower and upper molars, and in gingival recession and root resorption at the end of the treatment. Additionally, the young patient's experience using the appliances will be assessed. The primary outcome measure will be the amount of lower incisor proclination at the end of treatment. This will be assessed by cone beam computed tomography (CBCT) superimposition. Secondary outcome measures will be the changes in the mandible, maxilla, lower and upper molars at the end of treatment assessed by tomography superimposition and the young patient's experience using the appliances assessed by self-reported questionnaires and semi structured interviews. The randomisation method will be blocked randomisation, using software to generate a randomised list. The allocation concealment will be done in opaque envelopes numbered from 1 to 40 containing the treatment modality. The randomisation will be implemented by the secretary of the Department of Orthodontics of Rio de Janeiro State University before the beginning of the study. The patients and the orthodontists who will treat the patients cannot be blinded, as they will know the type of appliance used. The technician who will take the CBCT image and the data analyst will be blinded to patients' group allocation. DISCUSSION: If this new intervention is effective, the findings can change orthodontic practice and may also be relevant to other forms of treatment in which appliances are fixed to the bones of the jaws. However, if the bone anchoring is not effective, the trial will provide much needed information on the use of this comparatively new development. TRIAL REGISTRATION: ClinicalTrials.gov, protocol ID: NCT0241812 . Registered on 26 March 2015. PMID- 29178934 TI - Effectiveness of case management in the prevention of COPD re-admissions: a pilot study. AB - BACKGROUND: Chronic obstructive pulmonary disease (COPD) exacerbations are associated with high disease burden and costs, especially in the case of hospitalizations. The overall number of hospital admissions due to exacerbations of COPD has increased. It is remarkable that re-admissions account for a substantial part of these hospitalizations. This pilot study investigates the use of case management to reduce re-admissions due to COPD. METHODS: COPD patients with more than one hospitalization per year due to an exacerbation were included. The participants (n = 10) were closely monitored and intensively coached for 20 weeks after hospitalization. The case manager provided care in a person-focused manner. The case manager informed and supported the patient, took action when relapse threatened, coordinated and connected primary and secondary care. Data of 12 months before and after start of the intervention were compared. Primary outcome was the difference in number of hospitalizations. Secondary outcomes were health-related quality of life (measured by the Clinical COPD Questionnaire, CCQ) and dyspnoea (measured by the MRC Dyspnoea Scale). RESULTS: The incidence rate of hospitalizations was found to be 2.25 times higher (95% confidence interval [CI] 1.3-3.9; P = 0.004) 12 months before compared with 12 months after the start of case management. COPD patients had a mean CCQ score of 3.3 (95% CI 2.8-3.8) before and 2.4 (95% CI 1.9-2.8) after 20 weeks of case management; a difference of 1.0 (95% CI 0.4-1.6; P = 0.001). The mean MRC scores showed no significant differences before (4.3; 95% CI 3.7-4.9) and after the case management period (3.9; 95% CI 3.2-4.6); a difference of 0.4 (95% CI - 0.1 to 0.9; P = 0.114). CONCLUSIONS: This pilot study shows that the number of COPD hospital re admissions decreased significantly after the introduction of a case manager. Moreover, there was an improvement in patient-reported health-related quality of life. PMID- 29178933 TI - The chronically inflamed central nervous system provides niches for long-lived plasma cells. AB - Although oligoclonal bands in the cerebrospinal fluid have been a hallmark of multiple sclerosis diagnosis for over three decades, the role of antibody secreting cells in multiple sclerosis remains unclear. T and B cells are critical for multiple sclerosis pathogenesis, but increasing evidence suggests that plasma cells also contribute, through secretion of autoantibodies. Long-lived plasma cells are known to drive various chronic inflammatory conditions as e.g. systemic lupus erythematosus, however, to what extent they are present in autoimmune central nervous system inflammation has not yet been investigated. In brain biopsies from multiple sclerosis patients and other neurological diseases, we could detect non-proliferating plasma cells (CD138+Ki67-) in the parenchyma. Based on this finding, we hypothesized that long-lived plasma cells can persist in the central nervous system (CNS). In order to test this hypothesis, we adapted the multiple sclerosis mouse model experimental autoimmune encephalomyelitis to generate a B cell memory response. Plasma cells were found in the meninges and the parenchyma of the inflamed spinal cord, surrounded by tissue areas resembling survival niches for these cells, characterized by an up-regulation of chemokines (CXCL12), adhesion molecules (VCAM-1) and survival factors (APRIL and BAFF). In order to determine the lifetime of plasma cells in the chronically inflamed CNS, we labeled the DNA of proliferating cells with 5-ethynyl-2'-deoxyuridine (EdU). Up to five weeks later, we could detect EdU+ long-lived plasma cells in the murine CNS. To our knowledge, this is the first study describing non proliferating plasma cells directly in the target tissue of a chronic inflammation in humans, as well as the first evidence demonstrating the ability of plasma cells to persist in the CNS, and the ability of the chronically inflamed CNS tissue to promote this persistence. Hence, our results suggest that the CNS provides survival niches for long-lived plasma cells, similar to the niches found in other organs. Targeting these cells in the CNS offers new perspectives for treatment of chronic autoimmune neuroinflammatory diseases, especially in patients who do not respond to conventional therapies.

AB - OBJECTIVE: Researchers have developed case definitions to estimate incidence and lifetime prevalence of depression and anxiety disorders in multiple sclerosis (MS) using administrative data. For policymakers however, the prevalence of a disease requiring ongoing treatment during a given period such as annual period prevalence may be more relevant for decision-making. We tested a case definition for annual period prevalence of depression and anxiety disorders in MS using administrative data. RESULTS: Using population-based administrative (health claims) data from Manitoba, Canada we identified 1922 persons with incident MS from 1989 to 2012, and 11,392 age, sex and geographically-matched controls from the general population. As compared to controls, MS patients had an elevated annual prevalence ratio of depression (1.77; 95% confidence interval [CI] 1.64, 1.91), and anxiety disorders (1.46; 95% CI 1.35, 1.58). The annual prevalence of depression in our matched cohort was similar to that observed in the 2012 Canadian Community Health Survey, although the annual prevalence of anxiety was slightly higher. Administrative data can be used to estimate the annual period prevalence of psychiatric disorders in MS. PMID- 29178936 TI - Diallyl disulphide inhibits apolipoprotein(a) expression in HepG2 cells through the MEK1-ERK1/2-ELK-1 pathway. AB - BACKGROUND: Lipoprotein(a) [LP(a)] is implicated as a common and independent risk factor for cardiovascular diseases. The therapeutic options currently available for reducing plasma LP(a) concentrations are limited. Diallyl disulphide (DADS), the main component of garlic, regulates lipid metabolism in hepatocytes and adipocytes through ERK1/2 signalling. This study aimed to assess the effect of DADS on apolipoprotein(a) [apo(a)] in HepG2 cells. We also determined the effects of DADS on apo(a) expression and secretion in HepG2 cells as well as the underlying mechanisms. METHODS: We examined the role of DADS on apo(a) expression in HepG2 cells by treating cell with different concentrations of DADS (10, 20, 40 and 80 MUg/mL) for 24 h or treating cells with 40 MUg/mL DADS for 0, 6, 12, 24 and 48 h. Then we used quantitative real-time PCR to analysis apo(a) mRNA levels, used Western blot to analysis apo(a) protein levels and used enzyme-linked immunosorbent assay to test apo(a) secreted levels. To farther determined the role of DADS, we applied Transfection of small interfering RNA to knockdown ELK 1levels and applied PD98059, a specific inhibitor of ERK1/2, to block ERK1/2 signal. RESULTS: The results show DADS inhibited apo(a) at both the mRNA and protein levels in HepG2 cells in a dose-dependent manner. DADS-mediated inhibition of apoa(a) expression in HepG2 cells was attenuated when the cells were cultured in medium containing PD98059 (ERK1/2 inhibitor) or were transfected with siRNAs against MEK1 or ELK-1. Overexpression of apo(a) yielded similar results. CONCLUSIONS: This study reveals that DADS can downregulate apo(a) expression in a dose-dependent manner via the MEK-ERK12-ELK-1 pathway.

PMID- 29178937 TI - An optimized background regimen design to evaluate the contribution of levofloxacin to multidrug-resistant tuberculosis treatment regimens: study protocol for a randomized controlled trial. AB - BACKGROUND: Current guidelines for treatment of multidrug-resistant tuberculosis (MDR-TB) are largely based on expert opinion and observational data. Fluoroquinolones remain an essential part of MDR-TB treatment, but the optimal dose of fluoroquinolones as part of the regimen has not been defined. METHODS/DESIGN: We designed a randomized, blinded, phase II trial in MDR-TB patients comparing across levofloxacin doses of 11, 14, 17 and 20 mg/kg/day, all within an optimized background regimen. We assess pharmacokinetics, efficacy, safety and tolerability of regimens containing each of these doses. The primary efficacy outcome is time to culture conversion over the first 6 months of treatment. The study aims to determine the area under the curve (AUC) of the levofloxacin serum concentration in the 24 hours after dosing divided by the minimal inhibitory concentration of the patient's Mycobacterium tuberculosis isolate that inhibits > 90% of organisms (AUC/MIC) that maximizes efficacy and the AUC that maximizes safety and tolerability in the context of an MDR-TB treatment regimen. DISCUSSION: Fluoroquinolones are an integral part of recommended MDR-TB regimens. Little is known about how to optimize dosing for efficacy while maintaining acceptable toxicity. This study will provide evidence to support revised dosing guidelines for the use of levofloxacin as part of combination regimens for treatment of MDR-TB. The novel methodology can be adapted to elucidate the effect of other single agents in multidrug antibiotic treatment regimens. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01918397 . Registered on 5 August 2013. PMID- 29178939 TI - Autocrine parathyroid hormone-like hormone promotes intrahepatic cholangiocarcinoma cell proliferation via increased ERK/JNK-ATF2-cyclinD1 signaling. AB - BACKGROUND AND AIMS: Intrahepatic cholangiocarcinoma (ICC) is an aggressive tumor with a high fatality rate. It was recently found that parathyroid hormone-like hormone (PTHLH) was frequently overexpressed in ICC compared with non-tumor tissue. This study aimed to elucidate the underlying mechanisms of PTHLH in ICC development. METHODS: The CCK-8 assay, colony formation assays, flow cytometry and a xenograft model were used to examine the role of PTHLH in ICC cells proliferation. Immunohistochemistry (IHC) and western blot assays were used to detect target proteins. Luciferase reporter, chromatin immunoprecipitation (ChIP) and DNA pull-down assays were used to verify the transcription regulation of activating transcription factor-2 (ATF2). RESULTS: PTHLH was significantly upregulated in ICC compared with adjacent and normal tissues. Upregulation of PTHLH indicated a poor pathological differentiation and intrahepatic metastasis. Functional study demonstrated that PTHLH silencing markedly suppressed ICC cells growth, while specific overexpression of PTHLH has the opposite effect. Mechanistically, secreted PTHLH could promote ICC cell growth by activating extracellular signal-related kinase (ERK) and c-Jun N-terminal kinase (JNK) signaling pathways, and subsequently upregulated ATF2 and cyclinD1 expression. Further study found that the promoter activity of PTHLH were negatively regulated by ATF2, indicating that a negative feedback loop exists. CONCLUSIONS: Our findings demonstrated that the ICC-secreted PTHLH plays a characteristic growth promoting role through activating the canonical ERK/JNK-ATF2-cyclinD1 signaling pathways in ICC development. We identified a negative feedback loop formed by ATF2 and PTHLH. In this study, we explored the therapeutic implication for ICC patients. PMID- 29178940 TI - Restoration of motor control and proprioceptive and cutaneous sensation in humans with prior upper-limb amputation via multiple Utah Slanted Electrode Arrays (USEAs) implanted in residual peripheral arm nerves. AB - BACKGROUND: Despite advances in sophisticated robotic hands, intuitive control of and sensory feedback from these prostheses has been limited to only 3-degrees-of freedom (DOF) with 2 sensory percepts in closed-loop control. A Utah Slanted Electrode Array (USEA) has been used in the past to provide up to 81 sensory percepts for human amputees. Here, we report on the advanced capabilities of multiple USEAs implanted in the residual peripheral arm nerves of human amputees for restoring control of 5 DOF and sensation of up to 131 proprioceptive and cutaneous hand sensory percepts. We also demonstrate that USEA-restored sensory percepts provide a useful source of feedback during closed-loop virtual prosthetic hand control. METHODS: Two 100-channel USEAs were implanted for 4-5 weeks, one each in the median and ulnar arm nerves of two human subjects with prior long-duration upper-arm amputations. Intended finger and wrist positions were decoded from neuronal firing patterns via a modified Kalman filter, allowing subjects to control many movements of a virtual prosthetic hand. Additionally, USEA microstimulation was used to evoke numerous sensory percepts spanning the phantom hand. Closed-loop control was achieved by stimulating via an electrode of the ulnar-nerve USEA while recording and decoding movement via the median-nerve USEA. RESULTS: Subjects controlled up to 12 degrees-of-freedom during informal, 'freeform' online movement decode sessions, and experienced up to 131 USEA-evoked proprioceptive and cutaneous sensations spanning the phantom hand. Independent control was achieved for a 5-DOF real-time decode that included flexion/extension of the thumb, index, middle, and ring fingers, and the wrist. Proportional control was achieved for a 4-DOF real-time decode. One subject used a USEA-evoked hand sensation as feedback to complete a 1-DOF closed-loop virtual-hand movement task. There were no observed long-term functional deficits due to the USEA implants. CONCLUSIONS: Implantation of high-channel-count USEAs enables multi degree-of-freedom control of virtual prosthetic hand movement and restoration of a rich selection of both proprioceptive and cutaneous sensory percepts spanning the hand during the short 4-5 week post-implant period. Future USEA use in longer term implants and in closed-loop may enable restoration of many of the capabilities of an intact hand while contributing to a meaningful embodiment of the prosthesis. PMID- 29178941 TI - S100A8/A9 and sRAGE kinetic after polytrauma; an explorative observational study. AB - BACKGROUND: Following tissue injury after trauma, the activation of innate immune pathways results in systemic inflammation, organ failure and an increased risk of infections. The objective of this study was to characterize the kinetics of the S100A8/S100A9 complex, a new-recognized alarmin, as well as its soluble receptor sRAGE, over time after trauma as potential early biomarkers of the risk of organ damage. METHODS: We collected comprehensive data from consenting patients admitted to an ICU following severe trauma. The blood samples were taken at Day 0 (admission), Day1, 3 and 5 S100A8/A9 and sRAGE were measured by ELISA. Biomarkers levels were reported as median (IQR). RESULTS: Thirty-eight patients sustaining in majority a blunt trauma (89%) with a median ISS of 39 were included. In this cohort, the S100A8/A9 complex increased significantly over time (p = 0.001), but its levels increment over time (D0 to D5) was significantly smaller in patients developing infection (7.6 vs 40.1 mcg/mL, p = 0.011). The circulating level of sRAGE circulating levels decreased over time (p < 0.0001) and was higher in patients who remained in shock on day 3 (550 vs 918 pg/mL; p = 0.02) or 5 (498 vs 644 pg/mL; p = 0.045). Admission sRAGE levels were significantly higher in non survivors (1694 vs 745 pg/mL; p = 0.015) and was higher in patients developing renal failure (1143 vs 696 pg/mL, p = 0.011). DISCUSSION: Our findings reveal an interesting association between the biomarker S100A8/9 least increase over time and the presence of infectious complication after trauma. We describe that the sRAGE decline over time is in relation with shock and markers of ischemic injury. We also confirm the association of sRAGE levels measured at admission with mortality and the development of renal failure. CONCLUSIONS: This work illustrates the importance of following the circulating level of biomarker overtime. The utilization of S1008/9 as a tool to stratify infection risk and trigger early interventions need to be validated prospectively. PMID- 29178942 TI - Antioxidant effect of aqueous extract of four plants with therapeutic potential on gynecological diseases; Semen persicae, Leonurus cardiaca, Hedyotis diffusa, and Curcuma zedoaria. AB - BACKGROUND: Little information is available concerning antioxidant effects of plant teas (water boiled) which are used more commonly in traditional Chinese medicine than other extracts. Thus, we addressed this issue by evaluating the ability of teas from four different plants with therapeutic potential on gynecological diseases. METHODS: The aqueous extracts of Semen persicae, Leonurus cardiaca, Hedyotis diffusa, and Curcuma zedoaria rhizome were prepared and then their effects on copper-induced low-density lipoprotein cholesterol (LDL-C) oxidation were evaluated by spectrophotometric method. Density gradient ultracentrifugation method was recruited to isolate LDL-C from healthy individuals. RESULTS: Our results showed that adding 10, 20, and 30 ul S. persicae could increase the lag phase duration of LDL-C oxidation compared with control reaction 12, 21, and 33%, respectively. The most effective delay (87%) was observed when 30 ul H. diffusa was added to the reaction. In cases of L. cardiaca and C. zedoaria, we found no significant influence on the lag phase duration (p > 0.05). Moreover, our findings about starting point of the decomposition phase were almost in parallel with the lag phase results, as 30 ul of S. persicae or H. diffusa teas could significantly increase the initiation time of decomposition (p < 0.05). CONCLUSIONS: In conclusion our results showed that both S. persicae and H. diffusa teas and not L. cardiaca and C. zedoaria could have medicinal therapeutic effects partly through direct oxidation prevention. PMID- 29178944 TI - Malignant acanthosis nigricans: an early diagnostic clue for gastric adenocarcinoma. AB - BACKGROUND: Malignant acanthosis nigricans (MAN), characterized by the presence of a hyperpigmented, velvety cutaneous thickening, is recognized as a cutaneous sign of internal malignancy. Few MAN has been reported in the Asian race ever before. CASE PRESENTATION: Here, we report a rare case of MAN with severe mucosa and soles and extraordinary facial involvement in the Asian race. A 74-year-old man presented with hyperkeratotic eruption for 7 months. Physical examination revealed hyperkeratotic plaques on the face, dorsal skin of fingers and heels, and papillomatosis of buccal mucosa. Biopsy findings from skin lesion revealed hyperkeratosis, papillomatosis, and hyperpigmentation of the basal layer. The endoscopic ultrasound with biopsy of the gastric tissue revealed gastric cardia tubular adenocarcinoma. The patient was diagnosed with MAN associated with gastric adenocarcinoma, immediately following tumor resection and lymphadenectomy. A slight improvement was seen in the skin condition but died of cancer cachexia 3 months later. CONCLUSIONS: We report our typical patient to highlight the importance of MAN, which was an early clue to the discovery of gastric adenocarcinoma. PMID- 29178943 TI - High-volume hemofiltration in adult burn patients with septic shock and acute kidney injury: a multicenter randomized controlled trial. AB - BACKGROUND: Sepsis and septic shock occur commonly in severe burns. Acute kidney injury (AKI) is also common and often results as a consequence of sepsis. Mortality is unacceptably high in burn patients who develop AKI requiring renal replacement therapy and is presumed to be even higher when combined with septic shock. We hypothesized that high-volume hemofiltration (HVHF) as a blood purification technique would be beneficial in this population. METHODS: We conducted a multicenter, prospective, randomized, controlled clinical trial to evaluate the impact of HVHF on the hemodynamic profile of burn patients with septic shock and AKI involving seven burn centers in the United States. Subjects randomized to the HVHF were prescribed a dose of 70 ml/kg/hour for 48 hours while control subjects were managed in standard fashion in accordance with local practices. RESULTS: During a 4-year period, a total of nine subjects were enrolled for the intervention during the ramp-in phase and 28 subjects were randomized, 14 each into the control and HVHF arms respectively. The study was terminated due to slow enrollment. Ramp-in subjects were included along with those randomized in the final analysis. Our primary endpoint, the vasopressor dependency index, decreased significantly at 48 hours compared to baseline in the HVHF group (p = 0.007) while it remained no different in the control arm. At 14 days, the multiple organ dysfunction syndrome score decreased significantly in the HVHF group when compared to the day of treatment initiation (p = 0.02). No changes in inflammatory markers were detected during the 48-hour intervention period. No significant difference in survival was detected. No differences in adverse events were noted between the groups. CONCLUSIONS: HVHF was effective in reversing shock and improving organ function in burn patients with septic shock and AKI, and appears safe. Whether reversal of shock in these patients can improve survival is yet to be determined. TRIAL REGISTRATION: Clinicaltrials.gov NCT01213914 . Registered 30 September 2010. PMID- 29178945 TI - CRISPR/Cas9-mediated targeted chromosome elimination. AB - BACKGROUND: The CRISPR/Cas9 system has become an efficient gene editing method for generating cells carrying precise gene mutations, including the rearrangement and deletion of chromosomal segments. However, whether an entire chromosome could be eliminated by this technology is still unknown. RESULTS: Here we demonstrate the use of the CRISPR/Cas9 system to eliminate targeted chromosomes. Using either multiple cleavages induced by a single-guide RNA (sgRNA) that targets multiple chromosome-specific sites or a cocktail of multiple sgRNAs, each targeting one specific site, we found that a sex chromosome could be selectively eliminated in cultured cells, embryos, and tissues in vivo. Furthermore, this approach was able to produce a targeted autosome loss in aneuploid mouse embryonic stem cells with an extra human chromosome and human induced pluripotent stem cells with trisomy 21, as well as cancer cells. CONCLUSIONS: CRISPR/Cas9-mediated targeted chromosome elimination offers a new approach to develop animal models with chromosome deletions, and a potential therapeutic strategy for human aneuploidy diseases involving additional chromosomes. PMID- 29178947 TI - Dangguijakyak-san ameliorates memory deficits in ovariectomized mice by upregulating hippocampal estrogen synthesis. AB - BACKGROUND: Dangguijakyak-san (DJS) is an herbal formulation that has been clinically applicable for treating postmenopausal symptoms and neurological disorders. It is reported that hippocampal estrogen attenuates memory impairment via neuroprotection and synaptogenesis. However, the effect of DJS on hippocampal estrogen synthesis remains unknown. In this study, we explored the effect of DJS and its neuroprotective mechanism against memory impairment in ovariectomized (OVX) mice, with respect to hippocampal estrogen stimulation. METHODS: Cell cultures were prepared from the hippocampi of 18-day-old embryos from timed pregnant Sprague-Dawley rats. The hippocampi were dissected, collected, dissociated, and plated in 60-mm dishes. The cells were treated with DJS for 48 h and the supernatant was collected to determine estrogen levels. Female ICR mice (8-weeks-old) were housed for 1 week and ovariectomy was performed to remove the influence of ovary-synthesized estrogens. Following a 2-week post-surgical recovery period, the mice were administrated with DJS (50 and 100 mg/kg/day, p.o.) or 17beta-estradiol (200 MUg/kg/day, i.p.) once daily for 21 days. Hippocampal and serum estrogen levels were determined using enzyme-linked immunosorbent assay kit. Memory behavioral tests, western blot, and immunohistochemical analyses were performed to evaluate the neuroprotective effects of DJS in this model. RESULTS: DJS treatment promoted estrogen synthesis in primary hippocampal cells and the hippocampus of OVX mice, resulting in the amelioration of OVX-induced memory impairment. Hippocampal estrogen stimulated by DJS treatment contributed to the activation of cAMP response element-binding protein and synaptic protein in OVX mice. CONCLUSION: DJS may attenuate memory deficits in postmenopausal women via hippocampal estrogen synthesis. PMID- 29178946 TI - A putative causal relationship between genetically determined female body shape and posttraumatic stress disorder. AB - BACKGROUND: The nature and underlying mechanisms of the observed increased vulnerability to posttraumatic stress disorder (PTSD) in women are unclear. METHODS: We investigated the genetic overlap of PTSD with anthropometric traits and reproductive behaviors and functions in women. The analysis was conducted using female-specific summary statistics from large genome-wide association studies (GWAS) and a cohort of 3577 European American women (966 PTSD cases and 2611 trauma-exposed controls). We applied a high-resolution polygenic score approach and Mendelian randomization analysis to investigate genetic correlations and causal relationships. RESULTS: We observed an inverse association of PTSD with genetically determined anthropometric traits related to body shape, independent of body mass index (BMI). The top association was related to BMI adjusted waist circumference (WCadj; R = -0.079, P < 0.001, Q = 0.011). We estimated a relative decrease of 64.6% (95% confidence interval = 27.5-82.7) in the risk of PTSD per 1-SD increase in WCadj. MR-Egger regression intercept analysis showed no evidence of pleiotropic effects in this association (Ppleiotropy = 0.979). We also observed associations of genetically determined WCadj with age at first sexual intercourse and number of sexual partners (P = 0.013 and P < 0.001, respectively). CONCLUSIONS: There is a putative causal relationship between genetically determined female body shape and PTSD, which could be mediated by evolutionary mechanisms involved in human sexual behaviors. PMID- 29178948 TI - MiR-139 suppresses beta-casein synthesis and proliferation in bovine mammary epithelial cells by targeting the GHR and IGF1R signaling pathways. AB - BACKGROUND: MicroRNAs have important roles in many biological processes. However, the role of miR-139 in healthy mammary gland remains unclear. The objective of this study was to investigate the effects of miR-139 on lactation in dairy cows. RESULTS: Here, we found that miR-139 was down-regulated in mid-lactation dairy cow mammary tissues compared with mid-pregnancy tissues. Then, we prioritized two of potential target genes of miR-139 in cow, growth hormone receptor (GHR) and type I insulin-like growth factor receptor (IGF1R) for further functional studies based on their roles in lactation processes. Dual luciferase reporter assays validated direct binding of miR-139 to the 3'- untranslated region (UTR) of GHR and IGF1R. Moreover, over-expression or silencing of miR-139 affected mRNA levels of GHR and IGF1R in cultured bovine mammary epithelial cells (BMECs). Furthermore, over-expression of miR-139 decreased protein levels of beta-casein, proliferation in mammary epithelial cell, and the protein levels of IGF1R and key members of the GHR or IGF1R pathways as well, whereas silencing miR-139 produced the opposite result. Among these signal molecules, signal transducer and activator of transcription-5 (STAT5), protein kinase B (also known as AKT1), mammalian target of rapamycin (mTOR), and p70-S6 Kinase (p70S6K) are involed in beta-casein synthesis, and Cyclin D1 is involved in cell proliferation. In addition, silencing GHR decreased protein levels of beta-casein, IGF1R, and key members of the IGF1R pathway, whereas co-silencing miR-139 and GHR rescued the expression of GHR and reversed GHR silencing effects. CONCLUSIONS: Our results demonstrate that GHR and IGF1R are target genes of miR-139 in dairy cow. MiR-139 suppresses beta-casein synthesis and proliferation in BMECs by targeting the GHR and IGF1R signaling pathways. PMID- 29178949 TI - Valued experiences of graduate students in their role as educators in undergraduate training in Ugandan medical schools. AB - BACKGROUND: In most medical schools, graduate students, sometimes referred to as graduate teaching assistants, often participate in the training of undergraduate students. In developing countries like Uganda, are typically involved in undergraduate training. However, prior to this study there were no standard guidelines for this involvement. At the same time, the views and experiences of the graduate students in their role as educators had not been documented. Therefore, the aim of this study was to explore the views and experiences of graduate students about their involvement in undergraduate training in three Ugandan medical schools. The findings of this study will contribute to the development of policies for training in Ugandan medical schools. METHODS: This was a qualitative study in which thirty in-depth-interviews were conducted among second and third year graduate students in three Ugandan medical schools in the MESAU consortium (Medical Education Services to all Ugandans) including Mbarara University of Science and Technology, Makerere College of Health Sciences and Kampala International University, Western Campus. RESULTS: All graduate students from all the three medical schools viewed their involvement in undergraduate training as important. The study also revealed that graduate students increase available human resources and often compensate for the teaching missed when senior educators were absent. The graduate students expressed important views that need to be considered in the design of educational programs where they are to be involved. The respondents also reported a number of challenges in this undertaking that included lack of motivation, lack of orientation and having heavy workloads. The presence and commitment of senior educators to guide and support the graduate students in teaching activities was viewed as one significant intervention that would increase the effectiveness of their educational contributions. CONCLUSIONS: Graduate students enjoy their involvement in the training of undergraduate students despite the various challenges they face. In some departments, the involvement of postgraduate trainees is critical to the viability of undergraduate medical training. PMID- 29178950 TI - Declining rates of sterilisation reversal procedures in western Australian women from 1990 to 2008: the relationship with age, hospital type and government policy changes. AB - BACKGROUND: Female sterilisation is usually performed on an elective basis at perceived family completion, however, around 1-3% of women who have undergone sterilisation elect to undergo sterilisation reversal (SR) at a later stage. The trends in SR rates in Western Australia (WA), proportions of SR procedures between hospital types (public and private), and the effects of Federal Government policies on these trends are unknown. METHODS: Using records from statutory state-wide data collections of hospital separations and births, we conducted a retrospective descriptive study of all women aged 15-49 years who underwent a SR procedure during the period 1st January 1990 to 31st December 2008 (n = 1868 procedures). RESULTS: From 1991 to 2007 the annual incidence rate of SR procedures per 10,000 women declined from 47.0 to 3.6. Logistic regression modelling showed that from 1997 to 2001 the odds of women undergoing SR in a private hospital as opposed to all other hospitals were 1.39 times higher (95% CI 1.07-1.81) and 7.51 times higher (95% CI 5.46-10.31) from 2002 to 2008. There were significant decreases in SR rates overall and among different age groups after the Federal Government interventions. CONCLUSION: Rates of SR procedures in WA have declined from 1990 to 2008, particularly following policy changes such as the introduction of private health insurance (PHI) policies. This suggests decisions to undergo SR may be influenced by Federal Government interventions. PMID- 29178951 TI - African animal trypanosomiasis as a constraint to livestock health and production in Karamoja region: a detailed qualitative and quantitative assessment. AB - BACKGROUND: Nagana (African Animal Trypanosomiasis-AAT) and tick-borne diseases (TBDs) constrain livestock production in most parts of sub-Saharan Africa. To this realisation, Uganda government set up an African trypanosomiasis (AT) control unit, which among other activities generates national tsetse control priority maps using apparent tsetse density data. Such maps underestimate mechanically transmitted AAT and thus ought to be refined using actual AT prevalence data. We therefore set out to generate up-to-date cattle and donkey trypanosomiasis prevalence data as well as find out the constraints to livestock production in Karamoja region in a bid to re-define AT control priority in this region. RESULTS: Livestock keepers and animal health workers indicated that TBDs and AAT were the most important livestock diseases in Karamoja region. The prevalence of Trypanosoma spp. in cattle and donkeys was 16.3% (95% CI: 12.4 21.1%) and 32.4% (95% CI; 20.2-47.6%) respectively. Trypanosoma vivax (12.1%) and Trypanosoma congolense savannah (29.6%) were the most prevalent Trypanosoma spp. in cattle and donkeys respectively. Majority of the cattle (85.7%) and more than half of the donkey (57.1%) herds were positive for Trypanosoma spp. CONCLUSIONS: African animal trypanosomiasis and TBDs are the most important constraints to livestock production in Karamoja region. In order to improve livestock production and hence Karamajong livelihoods, government of Uganda and her development partners will need to invest in livestock health programs particularly targeting tsetse and TBD control. PMID- 29178952 TI - Status of benzimidazole resistance in intestinal nematode populations of livestock in Brazil: a systematic review. AB - BACKGROUND: Benzimidazoles (BZ) are a class of drugs widely used in veterinary and human medicine, creating a great selection pressure and the emergence of BZ resistance. We conducted a systematic review to assess the status of resistance and/or effectiveness reduction of BZ drugs in animal nematodes in Brazil, and make information accessible to the scientific community, as many studies are published in Portuguese. PubMed, SciELO Brasil, LILACS/Bireme, GNTD database, and Google Scholar were searched with no language restrictions. RESULTS: A total of 40 studies met our eligibility criteria (from the year 1989 forward). Sheep was the host most frequently analysed, and albendazole was the most frequently drug studied. The majority of studies (75.7%) showed that BZ drugs are insufficiently active (FECRT <80%) against nematode parasites of livestock. The mean FECRT for fenbendazole, thiabendazole, albendazole, mebendazole, oxfendazole, and ricobendazole were 71.8%, 71.8%, 58.6%, 53.9%, 46.9%, and 41.5%, respectively. It was observed through linear regression that FECRT is significantly reduced over time between 2007 and 2014 (R = -0.653 p = 0.021) for the treatment of cattle with BZ, suggesting progressive loss of effectiveness and increased resistance for these hosts. CONCLUSIONS: The scenario of BZ resistance in nematode populations in Brazil is not favourable. Given the high cost of drug discovery and development, it is urgent to implement control measures and to monitor the effectiveness/resistance to nematodes in livestock in Brazil. PMID- 29178953 TI - Video laryngoscopy does not improve the intubation outcomes in emergency and critical patients - a systematic review and meta-analysis of randomized controlled trials. AB - BACKGROUND: There is significant controversy regarding the influence of video laryngoscopy on the intubation outcomes in emergency and critical patients. This systematic review and meta-analysis was designed to determine whether video laryngoscopy could improve the intubation outcomes in emergency and critical patients. METHODS: We searched the Cochrane Central Register of Controlled Trials, PubMed, Embase, and Scopus databases from database inception until 15 February 2017. Only randomized controlled trials comparing video and direct laryngoscopy for tracheal intubation in emergency department, intensive care unit, and prehospital settings were selected. The primary outcome was the first attempt success rate. Review Manager 5.3 software was used to perform the pooled analysis and assess the risk of bias for each eligible study. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) system was used to assess the quality of evidence for all outcomes. RESULTS: Twelve studies (2583 patients) were included in the review for data extraction. Pooled analysis did not show an improved first-attempt success rate using video laryngoscopy (relative risk [RR], 0.93; P = 0.28; low-quality evidence). There was significant heterogeneity among studies (I 2 = 91%). Subgroup analyses showed that, in the prehospital setting, video laryngoscopy decreased the first-attempt success rate (RR, 0.57; P < 0.01; high-quality evidence) and overall success rate (RR, 0.58; 95% CI, 0.48-0.69; moderate-quality evidence) by experienced operators, whereas in the in-hospital setting, no significant difference between two devices was identified for the first-attempt success rate (RR, 1.06; P = 0.14; moderate quality evidence), regardless of the experience of the operators or the types of video laryngoscopes used (P > 0.05), although a slightly higher overall success rate was shown (RR, 1.11; P = 0.03; moderate-quality evidence). There were no differences between devices for other outcomes (P > 0.05), except for a lower rate of esophageal intubation (P = 0.01) and a higher rate of Cormack and Lehane grade 1 (P < 0.01) when using video laryngoscopy. CONCLUSIONS: On the basis of the results of this study, we conclude that, compared with direct laryngoscopy, video laryngoscopy does not improve intubation outcomes in emergency and critical patients. Prehospital intubation is even worsened by use of video laryngoscopy when performed by experienced operators. PMID- 29178954 TI - The effectiveness of topical colloidal silver in recalcitrant chronic rhinosinusitis: a randomized crossover control trial. AB - BACKGROUND: Recalcitrant chronic rhinosinusitis without polyposis (CRSsP) is a challenging condition to manage as traditional medical therapies and surgery fail to provide satisfactory clinical improvements. Colloidal silver (CS), a widely used naturopathic agent, has recently shown anti-biofilm properties both in vitro and within a rhinosinusitis animal model. To date, no trials involving humans have been published in world literature. The purpose of this study was to assess the efficacy of CS as a topical nasal spray in patients with refractory CRSsP. METHODS: A prospective cohort study was conducted using a convenience sample of 20 randomized patients with crossover methodology, comparing nasal sprays with CS versus saline. Patients sprayed twice daily for six weeks with the first intervention and then switched to the second for the next six weeks, with measurements made at baseline and each time point. Primary outcomes were changes in SNOT-22 and Lund-Kennedy (LK) endoscopic scores. All analysis was non parametric and was conducted using STATA 14. RESULTS: Twenty-two patients were enrolled in the study with 20 completing the entire protocol. Mean 6-week change in SNOT-22 scores were -2.8 and 1.0 for saline and CS, respectively (p = 0.373). Similarly, mean 6-week change in LK scores were -1.4 and -1.1 for saline and CS, respectively (p = 0.794). Significant period effects were observed with the SNOT 22 score between the randomized groups. No participants experienced negative health effects directly attributable to the administration of intranasal CS. CONCLUSION: Commercially available CS nasal spray did not demonstrate any meaningful subjective or objective improvements in patients with recalcitrant CRSsP. TRIAL REGISTRATION: NCT02403479 .

PMID- 29178955 TI - Cost evaluation, quality of life and pelvic organ function of three approaches to hysterectomy for benign uterine conditions: study protocol for a randomized controlled trial. AB - BACKGROUND: Hysterectomy is the commonest major gynaecological surgery. Although there are many approaches to hysterectomy, which depend on clinical criteria, certain patients may be eligible to be operated in any of the several available approaches. However, most comparative studies on hysterectomy are between two approaches. There is also a relative absence of data on long-term outcomes on quality of life and pelvic organ function. There is no single study which has considered quality of life, pelvic organ function and cost-effectiveness for the three main types of hysterectomy. Therefore, the objective of this study is to provide evidence on the optimal route of hysterectomy in terms of cost effectiveness by way of a three-armed randomized control study between non descent vaginal hysterectomy, total laparoscopic hysterectomy and total abdominal hysterectomy. METHODS: A multicentre three-armed randomized control trial is being conducted at the professorial gynaecology unit of the North Colombo Teaching Hospital, Ragama, Sri Lanka and gynaecology unit of the District General Hospital, Mannar, Sri Lanka. The study population is women needing hysterectomy for non-malignant uterine causes. Patients with a uterus > 14 weeks, previous pelvic surgery, those requiring incontinence surgery or pelvic floor surgery, any medical illness which caution/contraindicate laparoscopic surgery and who cannot read and write will be excluded. The main exposure variable is non-descent vaginal hysterectomy and total laparoscopic hysterectomy. The control group will be patients undergoing total abdominal hysterectomy. The primary outcome is time to recover following surgery, which is the earliest time to resume all of the usual activities done prior to surgery. In total, 147 patients (49 per arm) are needed to have 80% power at alpha-0.01 considering a loss to follow-up of 20% to detect a 7-day difference between the three routes; TLH versus TAH versus NDVH. The economic evaluation will take a societal perspective and will include direct costs in relation to allocation of healthcare resources and indirect costs which are borne by the patient. A micro-costing approach will be adopted to calculate direct costs from the time of presentation to the gynaecology clinic up to 6 months after surgery. Incremental cost-effectiveness ratios (ICER) will be obtained by calculating the incremental costs divided by the incremental effects (time to recover and QALYs gained) for the intervention groups (NDVH and TLH) over the standard care (TAH) group. DISCUSSION: The cost of the procedure, quality of life and pelvic organ function following the three main routes of hysterectomy are important to clinicians and healthcare providers, both in developed and developing countries. TRIAL REGISTRATION: The study was registered in the Sri Lanka clinical trials registry (SLCTR/2016/020) and the International Clinical Trials Registry Platform ( U1111-1194-8422 ) on 26 July 2016. PMID- 29178956 TI - Brucella seroprevalence in cattle near a wildlife reserve in Kenya. AB - OBJECTIVES: Brucellosis is caused by bacteria from the genus Brucella which infect human and domestic animals as well as wildlife. The Maasai Mara National Reserve has vast populations of wild ruminants such as buffaloes and wildebeest which could contribute to the risk of brucellosis in livestock, and the surrounding pastoralist communities grazing cattle in and around the reserve may be exposed to a higher risk of zoonotic diseases like brucellosis due to the close contact with livestock. In this study, cattle from three villages at varying distance from the reserve, were screened for antibodies against Brucella abortus. RESULTS: In total, 12.44% of 225 sampled animals were seropositive, with more females (15%) infected than males (5%). Seroprevalence was higher in livestock closer to Maasai Mara with the cattle in the village Mara Rianta having an odds ratio of 7.03 compared to Endoinyo Narasha further away (95% CI 1.4-11.1, p = 0.003), suggesting that a closer contact with wildlife may increase the circulation of infectious diseases between livestock and wildlife. Symptoms consistent with brucellosis were reported to occur in both humans and animals, and we thus conclude that brucellosis may be an important problem, both for the health and the economy. PMID- 29178958 TI - Gene expression of bovine embryos developing at the air-liquid interface on oviductal epithelial cells (ALI-BOEC). AB - We recently developed an air-liquid interface long-term culture of differentiated bovine oviductal epithelial cells (ALI-BOEC). This ex vivo oviduct epithelium is capable of supporting embryo development in co-culture up to the blastocyst stage without addition of embryo culture medium. However, blastocyst rates in co culture were markedly lower than in conventional in vitro embryo production procedures. In the present study, we assessed target gene expression of ALI-BOEC derived embryos to test their similarity to embryos from conventional in vitro embryo culture. We screened previously published data from developing bovine embryos and selected 41 genes which are either differentially expressed during embryo development, or reflect differences between various in vitro culture conditions or in vitro and in vivo embryos. Target gene expression was measured in 8-cell embryos and blastocysts using a 48.48 Dynamic ArrayTM on a Biomark HD instrument. For comparison with the ALI-BOEC system, we generated embryos by two different standard IVP protocols. The culture conditions lead to differential gene expression in both 8-cell embryos and blastocysts. Across the expression of all target genes the embryos developing on ALI-BOEC did not depart from conventional IVP embryos. These first results prove that gene expression in ALI BOEC embryos is not largely aberrant. However, there was no clear indication for a more in vivo-like target gene expression of these embryos. This calls for further optimization of the ALI-BOEC system to increase its efficiency both quantitatively and qualitatively. PMID- 29178957 TI - Triple combination antibiotic therapy for carbapenemase-producing Klebsiella pneumoniae: a systematic review. AB - BACKGROUND: The spread of carbapenemase-producing K. pneumoniae (CPKP) has become a significant problem worldwide. Combination therapy for CPKP is encouraging, but polymyxin resistance to many antibiotics is hampering effective treatment. Combination therapy with three or more antibiotics is being increasingly reported, therefore we performed a systematic review of triple combination cases in an effort to evaluate their clinical effectiveness for CPKP infections. METHODS: The PubMed database was searched to identify all published clinical outcomes of CPKP infections treated with triple combination therapy. Articles were stratified into two tiers depending on the level of clinical detail provided. A tier 1 study included: antibiotic regimen, regimen-specific outcome, patient status at onset of infection, and source of infection. Articles not reaching these criteria were considered tier 2. RESULTS: Thirty-three studies were eligible, 23 tier 1 and ten tier 2. Among tier 1 studies, 53 cases were included in this analysis. The most common infection was pneumonia (31%) followed by primary or catheter-related bacteremia (21%) and urinary tract infection (17%). Different combinations of antibiotic classes were utilized in triple combinations, the most common being a polymyxin (colistin or polymyxin B, 86.8%), tigecycline (73.6%), aminoglycoside (43.4%), or carbapenem (43.4%). Clinical and microbiological failure occurred in 14/39 patients (35.9%) and 22/42 patients (52.4%), respectively. Overall mortality for patients treated with triple combination therapy was 35.8% (19/53 patients). CONCLUSIONS: Triple combination therapy is being considered as a treatment option for CPKP. Polymyxin-based therapy is the backbone antibiotic in these regimens, but its effectiveness needs establishing in prospective clinical trials. PMID- 29178959 TI - Sugar Lego: gene composition of bacterial carbohydrate metabolism genomic loci. AB - BACKGROUND: Bacterial carbohydrate metabolism is extremely diverse, since carbohydrates serve as a major energy source and are involved in a variety of cellular processes. Bacterial genes belonging to same metabolic pathway are often co-localized in the chromosome, but it is not a strict rule. Gene co-localization in linked to co-evolution and co-regulation. This study focuses on a large-scale analysis of bacterial genomic loci related to the carbohydrate metabolism. RESULTS: We demonstrate that only 53% of 148,000 studied genes from over six hundred bacterial genomes are co-localized in bacterial genomes with other carbohydrate metabolism genes, which points to a significant role of singleton genes. Co-localized genes form cassettes, ranging in size from two to fifteen genes. Two major factors influencing the cassette-forming tendency are gene function and bacterial phylogeny. We have obtained a comprehensive picture of co localization preferences of genes for nineteen major carbohydrate metabolism functional classes, over two hundred gene orthologous clusters, and thirty bacterial classes, and characterized the cassette variety in size and content among different species, highlighting a significant role of short cassettes. The preference towards co-localization of carbohydrate metabolism genes varies between 40 and 76% for bacterial taxa. Analysis of frequently co-localized genes yielded forty-five significant pairwise links between genes belonging to different functional classes. The number of such links per class range from zero to eight, demonstrating varying preferences of respective genes towards a specific chromosomal neighborhood. Genes from eleven functional classes tend to co-localize with genes from the same class, indicating an important role of clustering of genes with similar functions. At that, in most cases such co localization does not originate from local duplication events. CONCLUSIONS: Overall, we describe a complex web formed by evolutionary relationships of bacterial carbohydrate metabolism genes, manifested as co-localization patterns.

PMID- 29178960 TI - The impact of a physician detailing and sampling program for generic atorvastatin: an interrupted time series analysis. AB - BACKGROUND: In 2011, Manitoba implemented a province-wide program of physician detailing and free sampling for generic atorvastatin to increase use of this generic statin. We examined the impact of this unique combined program of detailing and sampling for generic atorvastatin on the use and cost of statin medicines, market share of generic atorvastatin, the choice of starting statin for new users, and switching from a branded statin to generic atorvastatin. METHODS: We conducted a retrospective study of Manitoba insurance claims data for all continuously enrolled patients who filled one or more prescriptions for a statin between 2008 and 2013. Data were linked to physician-level data on the number of detailing visits and sample provision. We used interrupted time series analyses to assess policy-related changes in the use and cost of statin medicines, market share of generic atorvastatin, the choice of starting statin for new users, and switching from a branded statin to generic atorvastatin. RESULTS: The detailing program reached 31% (651/2103) of physicians who prescribed a statin during the study period. Collectively, these physicians prescribed 61% of statins dispensed in the province. Free sample cards were provided to 61% (394/651) of the detailed physicians. The program did not change the level or trend in the overall statin use rate and the total cost of statins or increase the number of patients switching from another branded statin to generic atorvastatin. We found the program had a small impact on atorvastatin's market share of new prescriptions, with a level increase of 2.6%. CONCLUSIONS: Though physician detailers were skilled at targeting high-prescribing physicians, a combined program of detailing visits and sample provision for generic atorvastatin did not lower overall statin costs or lead to switching from branded statins to the generic. The preceding introduction of generic atorvastatin appeared sufficient to modify prescribing patterns and decrease costs. PMID- 29178962 TI - Further psychometric validation of the BODY-Q: ability to detect change following bariatric surgery weight gain and loss. AB - BACKGROUND: Recent systematic reviews have identified that current patient reported outcome instruments have content limitations when used to measure change following bariatric surgery. The aim of this study was to measure change after bariatric surgery using the BODY-Q, a PRO instrument designed for weight loss and body contouring. METHODS: The BODY-Q is composed of 18 independently functioning scales and an obesity-specific symptom checklist that measure appearance, health related quality of life (HR-QOL) and experience of health-care. The sample for this study included patients who were exploring or seeking bariatric surgery in Hamilton (Canada) at the time of the BODY-Q field-test study and who agreed to further contact from the research team. These patients were invited to complete 12 BODY-Q scales and the symptom checklist between 7 June 2016 and 29 November 2016. Data were collected online (REDCap) and via postal surveys. Clinical change was measured using paired t-tests with effect sizes and standardized response means. RESULTS: The survey was completed by 58 of 89 (65%) pre-bariatric participants from the original BODY-Q field-test sample. The non-participants did not differ from participants in terms of age, gender, ethnicity, BMI or initial BODY-Q scale scores. Participants who had undergone bariatric surgery had a mean BMI of 49 (SD = 7) at time 1 and 35 (SD = 7) at time 2. Time since bariatric surgery was on average 2 years (SD = 0.5) (range 0.4 to 3 years). Percentage total weight loss ranged from 12 to 51 (mean 31, SD = 9). The difference in the proportion of patients to report an obesity-specific symptom on the BODY-Q checklist was significantly lower at follow-up for 5 of 10 symptoms. Participants improved on BODY-Q scales measuring appearance (of abdomen, back, body, buttocks, hips/outer thighs, inner thigh), body image and physical function (p < 0.001 on paired t-tests) and social function (p = 0.002 on paired t-test). These changes were associated with moderate to large effect sizes (0.60 to 2.29) and standardized response means (0.47 to 1.35). CONCLUSIONS: The BODY-Q provides a set of independently functioning scales that measure issues important to patients who undergo weight loss. BODY-Q scales were responsive to measuring clinical change associated with weight loss 2 years after bariatric surgery. PMID- 29178963 TI - Chloral hydrate enteral infusion for sedation in ventilated children: the CHOSEN pilot study. AB - BACKGROUND: We aimed to test a novel method of delivery of chloral hydrate (CH) sedation in ventilated critically ill young children. METHODS: Children < 12 years old, within 72 hours of admission, who were ventilated, receiving enteral tube-feeds, with intermittent CH ordered were enrolled after signed consent. Patients received a CH loading-dose of 10 mg/kg enterally, then a syringe-pump enteral infusion at 5 mg/kg/hour, increasing to a maximum of 9 mg/kg/hour. Cases were compared to historical controls matched for age group and Pediatric Risk of Mortality score (PRISM) category, using Fisher's exact test and the t test. The primary outcome was feasibility, defined as the use of an enteral CH continuous infusion without discontinuation attributable to a pre-specified potential harm. RESULTS: There were 21 patients enrolled, at age 11.4 (12.1) months, with bronchiolitis in 10 (48%), a mean Pediatric Logistic Organ Dysfunction (PELOD) score of 6.2 (5.2), and having received enteral CH continuous infusion for 4.5 (2.2) days. Infusion of CH was feasible in 20/21 (95%; 95% CI 76-99%) patients, with one (5%) adverse event of duodenal ulcer perforation on day 3 in a patient with croup receiving regular ibuprofen and dexamethasone. The CH infusion dose (mg/kg/h) on day 2 (n = 20) was 8.9 (IQR 5.9, 9), and on day 4 (n = 11) was 8.8 (IQR 7, 9). Days to titration of adequate sedation (defined as <= 3 PRN doses/shift) was 1 (IQR 0.5, 2.5), and hours to awakening for extubation was 5 (IQR 2, 9). Cases (versus controls) had less positive fluid balance at 48 h (-2 (45) vs. 26 (46) ml/kg, p = 0.051), and a decrease in number of PRN sedation doses from 12 h pre to 12 hours post starting CH (4.7 (3.3) to 2.6 (2.8), p = 0.009 versus 2.9 (3.9) to 3.4 (5), p = 0.74). There were no statistically significant differences between cases and controls in inotrope scores, signs or treatment of withdrawal, or PICU days. CONCLUSIONS: Delivering CH by continuous enteral infusion is feasible, effective, and may be associated with less positive fluid balance. Whether there is a risk of duodenal perforation requires further study. PMID- 29178961 TI - The unrecognized occupational relevance of the interaction between engineered nanomaterials and the gastro-intestinal tract: a consensus paper from a multidisciplinary working group. AB - BACKGROUND: There is a fundamental gap of knowledge on the health effects caused by the interaction of engineered nanomaterials (ENM) with the gastro-intestinal tract (GIT). This is partly due to the incomplete knowledge of the complex physical and chemical transformations that ENM undergo in the GIT, and partly to the widespread belief that GIT health effects of ENM are much less relevant than pulmonary effects. However, recent experimental findings, considering the role of new players in gut physiology (e.g. the microbiota), shed light on several outcomes of the interaction ENM/GIT. Along with this new information, there is growing direct and indirect evidence that not only ingested ENM, but also inhaled ENM may impact on the GIT. This fact, which may have relevant implications in occupational setting, has never been taken into consideration. This review paper summarizes the opinions and findings of a multidisciplinary team of experts, focusing on two main aspects of the issue: 1) ENM interactions within the GIT and their possible consequences, and 2) relevance of gastro-intestinal effects of inhaled ENMs. Under point 1, we analyzed how luminal gut-constituents, including mucus, may influence the adherence of ENM to cell surfaces in a size-dependent manner, and how intestinal permeability may be affected by different physico chemical characteristics of ENM. Cytotoxic, oxidative, genotoxic and inflammatory effects on different GIT cells, as well as effects on microbiota, are also discussed. Concerning point 2, recent studies highlight the relevance of gastro intestinal handling of inhaled ENM, showing significant excretion with feces of inhaled ENM and supporting the hypothesis that GIT should be considered an important target of extrapulmonary effects of inhaled ENM. CONCLUSIONS: In spite of recent insights on the relevance of the GIT as a target for toxic effects of nanoparticles, there is still a major gap in knowledge regarding the impact of the direct versus indirect oral exposure. This fact probably applies also to larger particles and dictates careful consideration in workers, who carry the highest risk of exposure to particulate matter. PMID- 29178964 TI - Over-expression of miR-146b and its regulatory role in intestinal epithelial cell viability, proliferation, and apoptosis in piglets. AB - BACKGROUND: Weaning stress affects the small intestine of piglets. MiR-146b is differentially expressed in suckling and weaned piglets. In this study, we evaluated the effects of miR-146b on cell viability, proliferation, and apoptosis in IPEC-J2 cells. RESULTS: Transfection with miR-146b mimics successfully increased miR-146b levels by 1000* (P < 0.001). The over-expression of miR-146b significantly promoted the apoptosis (P < 0.01) of IPEC-J2 cells, with no significant effects on cell viability or proliferation. MiR-146b suppressed the luciferase activity of the miR-TLR4-wt by 57% compared with the negative control, while mutation of the miR-146b binding site significantly blocked the suppressive effect (P < 0.05). Western blot results showed that TLR4 levels decreased in IPEC J2 cells transfected with miR-146b mimics (P < 0.05). CONCLUSIONS: The over expression of miR-146b promotes IPEC-J2 cell apoptosis. TLR4 is a direct target of miR-146b in IPEC-J2 cells. REVIEWERS: This article was reviewed by Eugene Berezikov and Jan B Hoek. PMID- 29178965 TI - A child with distal (type 1) renal tubular acidosis presenting with progressive gross motor developmental regression and acute paralysis. AB - BACKGROUND: Distal (Type 1) renal tubular acidosis (dRTA) is characterized by inability to secrete hydrogen irons from the distal tubule. The aetiology of dRTA is diverse and can be either inherited or acquired. Common clinical presentations of dRTA in the paediatric age group include polyuria, nocturia, failure to thrive, constipation, abnormal breathing and nephrolithiasis. Though persistent hypokalemia is frequently seen in dRTA, hypokalemic muscular paralysis is uncommon and rarely described in children. CASE PRESENTATION: Three and a half years old girl was referred for evaluation of progressive loss of gross motor milestones over 6 months and acute episode of paralysis. Her other developmental domains were age appropriate. Notably, there was no history of polyuria, polydipsia, nocturia and abnormal breathing. Physical examination revealed proximal myopathy (waddling gait and positive Gower's sign), diminished lower limb reflexes and muscle tone. Her serum potassium was low (2.1 meq/l) and she was subsequently investigated for hypokalemic paralysis. Diagnosis of distal renal tubular acidosis was made, based on hypokalemic hyperchloremic metabolic acidosis with normal anion gap, high urine pH, borderline hypercalciuria, medullary nephrocalcinosis and exclusion of other differential diagnosis. The child showed complete symptomatic recovery upon commencement of standard treatment for distal renal tubular acidosis. CONCLUSIONS: This case report highlights the importance of considering hypokalemia and renal tubular acidosis in the differential diagnosis of acute flaccid paralysis and proximal myopathy. Early diagnosis will prevent costly investigations and enable rapid clinical recovery in the affected child. PMID- 29178966 TI - Automated growth rate determination in high-throughput microbioreactor systems. AB - OBJECTIVE: The calculation of growth rates provides basic metric for biological fitness and is standard task when using microbioreactors (MBRs) in microbial phenotyping. MBRs easily produce huge data at high frequency from parallelized high-throughput cultivations with online monitoring of biomass formation at high temporal resolution. Resulting high-density data need to be processed efficiently to accelerate experimental throughput. RESULTS: A MATLAB code is presented that detects the exponential growth phase from multiple microbial cultivations in an iterative procedure based on several criteria, according to the model of exponential growth. These were obtained with Corynebacterium glutamicum showing single exponential growth phase and Escherichia coli exhibiting diauxic growth with exponential phase followed by retarded growth. The procedure reproducibly detects the correct biomass data subset for growth rate calculation. The procedure was applied on data set detached from growth phenotyping of library of genome reduced C. glutamicum strains and results agree with previously reported results where manual effort was needed to pre-process the data. Thus, the automated and standardized method enables a fair comparison of strain mutants for biological fitness evaluation. The code is easily parallelized and greatly facilitates experimental throughout in biological fitness testing from strain screenings conducted with MBR systems.

PMID- 29178968 TI - Cohort-specific imputation of gene expression improves prediction of warfarin dose for African Americans. AB - BACKGROUND: Genome-wide association studies are useful for discovering genotype phenotype associations but are limited because they require large cohorts to identify a signal, which can be population-specific. Mapping genetic variation to genes improves power and allows the effects of both protein-coding variation as well as variation in expression to be combined into "gene level" effects. METHODS: Previous work has shown that warfarin dose can be predicted using information from genetic variation that affects protein-coding regions. Here, we introduce a method that improves dose prediction by integrating tissue-specific gene expression. In particular, we use drug pathways and expression quantitative trait loci knowledge to impute gene expression-on the assumption that differential expression of key pathway genes may impact dose requirement. We focus on 116 genes from the pharmacokinetic and pharmacodynamic pathways of warfarin within training and validation sets comprising both European and African descent individuals. RESULTS: We build gene-tissue signatures associated with warfarin dose in a cohort-specific manner and identify a signature of 11 gene tissue pairs that significantly augments the International Warfarin Pharmacogenetics Consortium dosage-prediction algorithm in both populations. CONCLUSIONS: Our results demonstrate that imputed expression can improve dose prediction and bridge population-specific compositions.

PMID- 29178967 TI - Blocking ATP-sensitive potassium channel alleviates morphine tolerance by inhibiting HSP70-TLR4-NLRP3-mediated neuroinflammation. AB - BACKGROUND: Long-term use of morphine induces analgesic tolerance, which limits its clinical efficacy. Evidence indicated morphine-evoked neuroinflammation mediated by toll-like receptor 4 (TLR4) - NOD-like receptor protein 3 (NLRP3) inflammasome was important for morphine tolerance. In our study, we investigated whether other existing alternative pathways caused morphine-induced activation of TLR4 in microglia. We focused on heat shock protein 70 (HSP70), a damage associated molecular pattern (DAMP), which was released from various cells upon stimulations under the control of KATP channel and bound with TLR4-inducing inflammation. Glibenclamide, a classic KATP channel blocker, can improve neuroinflammation by inhibiting the activation of NLRP3 inflammasome. Our present study investigated the effect and possible mechanism of glibenclamide in improving morphine tolerance via its specific inhibition on the release of HSP70 and activation of NLRP3 inflammasome induced by morphine. METHODS: CD-1 mice were used for tail-flick test to evaluate morphine tolerance. The microglial cell line BV-2 and neural cell line SH-SY5Y were used to investigate the pharmacological effects and the mechanism of glibenclamide on morphine-induced neuroinflammation. The activation of microglia was accessed by immunofluorescence staining. Neuroinflammation-related cytokines were measured by western blot and real-time PCR. The level of HSP70 and related signaling pathway were evaluated by western blot and immunofluorescence staining. RESULTS: Morphine induced the release of HSP70 from neurons. The released HSP70 activated microglia and triggered TLR4 mediated inflammatory response, leading to the phosphorylation of p38 mitogen activated protein kinase (MAPK) and nuclear factor-kappaB (NF-kappaB) p65 and the activation of NLRP3 inflammasome. Moreover, anti-HSP70 neutralizing antibody partly attenuated chronic morphine tolerance. The secretion of HSP70 was under the control of MOR/AKT/KATP/ERK signal pathway. Glibenclamide as a classic KATP channel blocker markedly inhibited the release of HSP70 induced by morphine and suppressed HSP70-TLR4-NLRP3 inflammasome-mediated neuroinflammation, which consequently attenuated morphine tolerance. CONCLUSIONS: Our study indicated that morphine-induced extracellular HSP70 was an alternative way for the activation of TLR4-NLRP3 in analgesic tolerance. The release of HSP70 was regulated by MOR/AKT/KATP/ERK pathway. Our study suggested a promising target, KATP channel and a new leading compound, glibenclamide, for treating morphine tolerance.

AB - OBJECTIVES: This study aimed to evaluate the components of test-retest reliability including time interval, sample size, and statistical methods used in patient-reported outcome measures in older people and to provide suggestions on the methodology for calculating test-retest reliability for patient-reported outcomes in older people. DESIGN: This was a systematic literature review. DATA SOURCES: MEDLINE, Embase, CINAHL, and PsycINFO were searched from January 1, 2000 to August 10, 2017 by an information specialist. REVIEW METHODS: This systematic review was guided by both the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist and the guideline for systematic review published by the National Evidence-based Healthcare Collaborating Agency in Korea. The methodological quality was assessed by the Consensus-based Standards for the selection of health Measurement Instruments checklist box B. RESULTS: Ninety-five out of 12,641 studies were selected for the analysis. The median time interval for test-retest reliability was 14days, and the ratio of sample size for test retest reliability to the number of items in each measure ranged from 1:1 to 1:4. The most frequently used statistical methods for continuous scores was intraclass correlation coefficients (ICCs). Among the 63 studies that used ICCs, 21 studies presented models for ICC calculations and 30 studies reported 95% confidence intervals of the ICCs. Additional analyses using 17 studies that reported a strong ICC (>0.09) showed that the mean time interval was 12.88days and the mean ratio of the number of items to sample size was 1:5.37. CONCLUSIONS: When researchers plan to assess the test-retest reliability of patient-reported outcome measures for older people, they need to consider an adequate time interval of approximately 13days and the sample size of about 5 times the number of items. Particularly, statistical methods should not only be selected based on the types of scores of the patient-reported outcome measures, but should also be described clearly in the studies that report the results of test-retest reliability.

PARTICIPANTS: In total, 40 healthy female volunteers aged 20-45 years were recruited via e-mail. METHODS: Participants received 15min of local warming with a warmed heat pack (40+/-2 degrees C). The primary outcome was the cross sectional area of the target vein at 5, 10, and 15min of warming, which was measured after the intervention by blinded review using ultrasound. Secondary outcomes included forearm target site temperature at 5, 10, and 15min of local warming, which was measured with a temperature sensor and handheld thermometer. RESULTS: Compared to outcomes before local warming, vein cross-sectional area at 5, 10, and 15min of warming significantly (p <0.001) increased by 2.8, 2.9, and 2.3mm2. The target site temperature increased by 6.9 degrees C, 6.4 degrees C, and 6.0 degrees C, respectively. However, no significant differences were found in cross-sectional area among the time points of 5, 10, and 15min of local warming. The target site temperature at 15min of local warming was significantly (p < 0.001) different than that at 5 and 10min. No adverse events occurred with local warming. CONCLUSION: Compared with outcomes before local warming, vein size after warming for 5, 10, and 15min was significantly larger. No significant differences were found in vein size among the time points of 5, 10, and 15min of local warming. Our result demonstrated the effectiveness of shorter-duration (5min) local warming for inducing venodilation for peripheral intravenous cannulation.

AB - BACKGROUND: Unfavorable associations between air pollution and myocardial infarction are broadly investigated in recent studies and some of them revealed considerable associations; however, controversies exists between these investigations with regard to culprit components of air pollution and significance of correlation between myocardial infarction risk and air pollution. METHODS: The association between exposure to PM10, PM2.5, ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide concentration of background air that residents of Tehran, the capital city of Iran, which is ranked as the most air polluted city of Iran and the relative risk of developing ST-elevation myocardial infarction (STEMI) were investigated by a case-crossover design. Our study included 208 patients admitted with a diagnosis of STEMI and undergone primary percutaneous intervention. Air pollutant concentration was averaged in 24-h windows preceding the time of onset of myocardial infarction for the case period. Besides, the mean level of each element of air pollution of the corresponding time in one week, two weeks and three weeks before onset of myocardial infarction, was averaged separately for each day as one control periods. Thus, 624 control periods were included in our investigation such that. Each patient is matched and compared with him/herself. RESULTS: The mean level of PM10 in case periods (61.47ug/m3) was significantly higher than its level in control periods (57.86ug/m3) (P-value = 0.019, 95% CI: 1.002-1.018, RR = 1.010). Also, the mean level of PM2.5 in case periods (95.40ug/m3) was significantly higher than that in control days (90.88ug/m3) (P-value = 0.044, 95% CI: 1.001-1.011, RR = 1.006). The level of other components including NO2, SO2, CO and O3 showed no significant differences between case and control periods. A 10ug/m3 increase in PM10 and PM2.5 would result in 10.10% and 10.06% increase in STEMI event, respectively. Furthermore, the results of sub-group analysis showed that older patients (equal or more than 60 year-old), diabetic patients, non-hypertensive ones and patients with more than one diseased vessel may be more vulnerable to the harmful effect of particular matters including PM10 and PM2.5 on development of STEMI. CONCLUSION: Air pollution is a worldwide pandemic with great potential to cause terrible events especially cardiovascular ones. PM2.5 and PM10 are amongst ambient air pollutant with a high risk of developing STEMI. Thus, more restrictive legislations should be applied to define a safe level of indoor and outdoor air pollutant production. PMID- 29178980 TI - Ambient ultrafine particles activate human monocytes: Effect of dose, differentiation state and age of donors. AB - Exposure to ambient particulate matter (PM) has been linked to adverse pulmonary and cardiovascular health effects. Activation of both inflammatory and oxidative stress pathways has been observed and may be a probable cause of these outcomes. We tested the hypothesis that in human monocytes, PM-induced oxidative and inflammatory responses are interrelated. A human monocytic cell line (THP-1) was used to determine if dose and differentiation state plays a role in the cellular response after a 24hr exposure to particles. Primary human monocytes derived from eight female, non-smoker donors (aged: 21, 24, 27, 28, 48, 49, 54 & 60yo) were used to determine if the age of donors modulates the response. Cells were treated with aqueous suspensions of ambient ultrafine particles (UFP, defined as smaller than 0.2um in size) or a media control for 24hr. After exposure, reactive oxygen species (ROS) formation was increased irrespective of dose or differentiation state of THP-1 cells. In the primary human monocytes, ROS formation was not significantly changed. The release of the proinflammatory cytokine, tumor necrosis factor alpha (TNF-alpha), was dose-dependent and greatest in differentiated compared to undifferentiated THP-1 cells exposed to UFP. In the Primary human monocytes, TNF-alpha secretion was increased irrespective of the age of the donor. Our results suggest that after a 24hr exposure to particles, general reactive oxygen species formation was nonspecific and uncorrelated to cytokine secretion which was consistently enhanced. Cytokines play an important role in orchestrating many immune responses and thus the ability of ambient particles to enhance robust secretion of a proinflammatory cytokine from primary human monocytes, and how this may influence the response to pathogens and alter disease states, needs to be further evaluated. PMID- 29178979 TI - Unique pulmonary immunotoxicological effects of urban PM are not recapitulated solely by carbon black, diesel exhaust or coal fly ash. AB - BACKGROUND: Exposure to particulate matter (PM) is increasing worldwide as a result of increased human activity, the rapid industrialization of developing countries, and effects of climate change. Adverse effects of PM on human health are well documented, and because PM exposure occurs mostly through the airways, PM has especially deleterious impact on the lungs. OBJECTIVE: We investigated whether surrogate PM particles like carbon black (CB), diesel exhaust particle (DEP), coal fly ash (CFA) can recapitulate the allergic airway inflammatory response induced by urban particulate matter. METHODS: We compared the pro inflammatory potential of urban PM collected from New York (NYC) and Baltimore (Balt) with CB, DEP and CFA surrogate PM particles. Eight to ten weeks old BALB/cJ mice were exposed through the airways to particulate material, and markers of airway inflammation were determined. Specifically, we assessed cellular influx, mucus production, lung function, cytokine levels as well as immune cell profiling of the lungs. RESULTS: Herein, we demonstrate that exposure to equivalent mass of stand-alone surrogate PM particles like CB, DEP and CFA, fails to induce significant airway inflammatory response seen after similar exposure to urban PMs. Specifically, we observe that PM collected from New York (NYC) and Baltimore city (Balt) triggers a mixed Th2/Th17 response accompanied by eosinophilic and neutrophilic influx, mucus production and airway hyperresponsiveness (AHR). Although the immune profile of NYC and Baltimore PMs are similar, they demonstrate considerable differences in their potency. Baltimore PM induced more robust airway inflammation, AHR, and Th2 cytokine production, possibly due to the greater metal content in Baltimore PM. CONCLUSIONS: Urban particulate matter with its unique physiochemical properties and heterogeneous composition elicits a mixed Th2/Th17 allergic airway response that is not seen after similar exposures to surrogate PM particles. PMID- 29178981 TI - Translating Computer-Aided Design and Surgical Planning Into Successful Mandibular Reconstruction Using a Vascularized Iliac-Crest Flap. AB - PURPOSE: This study evaluated the computer-aided approach to the reconstruction of mandibular defects using a vascularized iliac-crest flap. MATERIALS AND METHODS: From December 2015 to October 2016, 14 patients (8 men and 6 women) 18 to 64 years old (median age, 29 yr) were treated at the Peking University School and Stomatology Hospital (Beijing, China). Biopsy specimens from all patients were subjected to histologic examination before segmental mandibulectomy. Computer-based surgical techniques, including virtual surgical planning, computer aided design and manufacturing, rapid prototyping, and intraoperative navigation, were used to restore the anatomic continuity and configuration of the mandible using a vascularized iliac-crest flap. Two transverse dimensions and 1 anteroposterior (A-P) dimension were evaluated based on the virtual plan and postoperative computed tomogram. Lines from condylar head to condylar head and from gonial angle to gonial angle were defined as the transverse dimensions. A perpendicular line drawn from the mandibular midline to the center point on the condylar head to condylar head measurement was defined as the A-P dimension. Complications were evaluated during follow-up. RESULTS: The flap success rate was 92.9% (13 of 14), with 1 flap failure. After the operation, there were no other serious complications in 13 of the 14 patients, who exhibited a good mandibular configuration with good occlusion. Furthermore, the height of bone graft was sufficient for implants. Healing of the recipient and donor sites with no serious complication was uneventful. The average surgical errors in the A-P dimension and transverse dimensions were 1.8 +/- 1.0 mm (range, 0.2 to 3.7 mm), 2.2 +/- 1.1 mm (range, 0.9 to 5.0 mm), and 2.6 +/- 1.6 mm (range, 0.3 to 7.2 mm), respectively. CONCLUSIONS: The use of these digital techniques was found to be a viable option for reconstruction of mandibular defects, but the results should be interpreted cautiously because of the small number of patients and the relatively short follow-up. PMID- 29178982 TI - Microbiology Alloplastic Total Joint Infections: A 20-Year Retrospective Study. AB - PURPOSE: Prosthetic joint infection (PJI) is a rare complication of temporomandibular joint replacement (TJR). This study evaluated TJR PJIs at the authors' institution over a 20-year period, including micro-organisms cultured, antibiotic resistance patterns, and intraoperative protocols of TJR. PATIENTS AND METHODS: Patients were identified using Current Procedural Terminology and International Classification of Diseases, Ninth Revision codes and surgical logs from January 1995 through 2015. Inclusion criteria were adults older than 18 years with previous alloplastic TJR and the presence of infection of the prosthesis at explantation. Exclusion criteria were patients younger than 18 years and who received hemiarthroplasty. Primary outcomes included culture data and antibiotic selection for PJI. Secondary outcomes included intraoperative duration and in vivo duration. RESULTS: Eleven patients were identified and 15 joints were explanted. Average length in vivo was 232 months (standard deviation, 478.9 months). Six percent (n = 1) were identified as early PJI (0 to 3 months), 46% (n = 7) were intermediate PJI (3 months to 2 yr), and 33% (n = 5) were late PJI (>2 yr). One patient could not be classified as early, intermediate, or late. Staphylococcus aureus was present in 53% of patients and was the predominant organism isolated. Propionibacterium acnes was isolated in 33% of patients. Penicillin was the antibiotic with the greatest organism resistance (46%). CONCLUSION: In the present study, the most commonly cultured organism was S aureus (53%), a finding consistent with current literature. The prevalence of P acnes colonization was noted in 33% of cases. Although the relevance of P acnes and its contribution to PJI requires further investigation, it is associated with PJI and biofilm formation. Based on this study, consideration could be given to the use of vancomycin and first-generation cephalosporins as perioperative antibiotic coverage. PMID- 29178983 TI - Hypofractionated radiotherapy for prostate cancer in the postoperative setting: What is the evidence so far? AB - Postoperative external beam radiation therapy (EBRT) is a validated treatment option in the adjuvant setting for prostate cancer patients with aggressive pathological features following radical prostatectomy (RP) or as salvage modality in patients with biochemical recurrence after RP. Contemporary randomized phase III trials have provided evidence for using hypofractionation in the definitive treatment setting as an alternative to standard fractionated regimens. Biomathematical modeling for prostate cancer fractionated EBRT associated with widely available refined treatment delivery techniques such as volumetric modulated-arc therapy with image-guided RT may improve the therapeutic ratio. Nevertheless, the role of hypofractionation in the postoperative setting still remains investigational. In this systematic review of the literature we reviewed the role of hypofractionation for postoperative EBRT in the adjuvant or salvage setting in prostate cancer patients previously treated by RP. A favorable acute toxicity profile with, at least, as good biochemical control rates with hypofractionation has been suggested. And yet conflicting results have been reported concerning long-term genitourinary late toxicity. Prospective studies are eagerly awaited to assess the role of hypofractionation in the postoperative setting. PMID- 29178984 TI - Moral imagination: Facilitating prosocial decision-making through scene imagery and theory of mind. AB - How we imagine and subjectively experience the future can inform how we make decisions in the present. Here, we examined a prosocial effect of imagining future episodes in motivating moral decisions about helping others in need, as well as the underlying cognitive mechanisms. Across three experiments we found that people are more willing to help others in specific situations after imagining helping them in those situations. Manipulating the spatial representation of imagined future episodes in particular was effective at increasing intentions to help others, suggesting that scene imagery plays an important role in the prosocial effect of episodic simulation. Path modeling analyses revealed that episodic simulation interacts with theory of mind in facilitating prosocial responses but can also operate independently. Moreover, we found that our manipulations of the imagined helping episode increased actual prosocial behavior, which also correlated with changes in reported willingness to help. Based on these findings, we propose a new model that begins to capture the multifaceted mechanisms by which episodic simulation contributes to prosocial decision-making, highlighting boundaries and promising future directions to explore. Implications for research in moral cognition, imagination, and patients with impairments in episodic simulation are discussed. PMID- 29178985 TI - A complementary role for tetraspanin superfamily member TSSC6 and ADP purinergic P2Y12 receptor in platelets. AB - Tumor-suppressing subchromosomal transferable fragment cDNA 6 (TSSC6) expression is restricted to hematopoietic organs and tissues where it plays a role in hematopoietic-cell function. The ADP purinergic receptor P2Y12 is mainly expressed by platelets with important clinical significance as a target for several clinically approved antithrombotic agents. We have previously shown a physical association between P2Y12 and TSSC6 in platelets. Hence our aim was to investigate whether this physical association is translated to functional effects. To investigate this possibility, we used wild-type or TSSC6 knockout (KO) mice treated with either PBS or 50mg/kg clopidogrel. TSSC6 KO mice treated with clopidogrel exhibited synergy in delayed kinetics of clot retraction, reduced collagen-mediated platelet aggregation, and platelet spreading on fibrinogen. Platelets derived from TSSC6 mice with P2Y12 blockade form smaller thrombi when perfused over a collagen matrix under arterial flow. Clopidogrel treated TSSC6 KO arterioles showed smaller and less stable thrombi with increased tendency to embolise in vivo. These studies demonstrate a complementary role between TSSC6 and P2Y12 receptor in platelets in regulating 'outside in' integrin alphaIIbbeta3 signalling thrombus growth and stability.

PMID- 29178987 TI - Time to threshold as a new indicator of circulatory state and prognosis in patients with pulmonary embolism. AB - BACKGROUND: Bolus tracking is commonly applied in computed tomography pulmonary angiography. The time that it takes for contrast to reach a predefined threshold in the pulmonary artery is called time to threshold (TTT). TTT could be associated with the circulatory state, and ultimately with prognosis in patients with PE. AIM: The purpose of the present study was to examine the correlation of TTT with embolus burden, radiological and clinical parameters of circulatory state, and ultimately with 30-day mortality. METHODS: In a single-center, retrospective study 50 patients with pulmonary embolism and contrast administration via central venous line were included. The Mastora score was used to quantify embolus burden. Radiological parameters of circulatory state were the ratio of the short axes of the right and left ventricle diameter and the reflux of contrast medium into the inferior vena cava. Clinical parameters of circulatory state were arterial pH, systolic blood pressure, heart rate, and the Acute Physiology and Chronic Health Evaluation II: APACHE II. Survival was defined as surviving the following 30days after the PE diagnosis. RESULTS: TTT was significantly correlated with all radiological and clinical parameters of circulatory state and with 30-day mortality. However, TTT is dependent on device specific and protocol specific factors. CONCLUSIONS: Higher TTT is associated with worse prognosis in patients with pulmonary embolism.

PMID- 29178989 TI - Interaction of factor VII activating protease (FSAP) with neutrophil extracellular traps (NETs). AB - The circulating zymogen form of Factor VII activating protease (FSAP) can be activated by histones and nucleosomes in vivo. These cell-death-associated nuclear factors are also actively extruded into the extracellular space by neutrophils through a process called neutrophil extracellular trap (NET) formation (NETosis). NETs are thought to be involved in host defense, inflammation as well as thrombosis. We have investigated the bidirectional interactions of FSAP and NETs. Phorbol ester-mediated NET formation was marginally stimulated by FSAP. Plasma-derived FSAP as well as exogenous FSAP bound to NETs. There was co-localization of FSAP and NETs in coronary thrombi from patients with acute myocardial infarction. Contrary to our expectations no activation of pro-FSAP by NETs was evident. However, after disintegration of NETs with DNase, a robust activation of pro-FSAP, due to release of histones from nucleosomes, was detected. The released histones were in turn degraded by FSAP. Histone cytotoxicity towards endothelial cells was neutralized by FSAP more potently than by activated protein C (APC). One more consequence of histone degradation was a decrease in nucleosome release from apoptotic neutrophils. Taken together, NETs bind to FSAP, but do not activate pro-FSAP unless histones are released from NETs by DNAse. This activation of FSAP is likely to be important in diminishing the cytotoxic effect of histones, thus limiting the damaging effect of NETosis. PMID- 29178990 TI - Variants in chondroitin sulfate metabolism genes in thrombotic storm. AB - INTRODUCTION: Thrombotic storm (TS) presents as a severe, acute thrombotic phenotype, characterized by multiple clotting events and frequently affecting younger adults. Understanding the extensive hypercoagulation of an extreme phenotype as TS will also provide insight into the pathogenesis of a wider spectrum of thrombotic disorders. MATERIAL AND METHODS: We completed whole exome sequencing on 26 TS patients, including 1 multiplex family, 13 trios and 12 isolated TS patients. We examined both dominant and recessive inheritance models for known thrombotic factors as well as performed a genome-wide screen. Identified genes of interest in the family and trios were screened in the remaining TS patients. Variants were filtered on frequency (<5% in 1000 genomes), conservation and function in gene and were annotated for effect on protein and overall functionality. RESULTS: We observed an accumulation of variants in genes linked to chondroitin sulfate (CS), but not heparan sulfate metabolism. Sixteen conserved, rare missense and nonsense variants in genes involved in CS metabolism (CHPF, CHPF2, CHST3, CHST12, CHST15, SLC26A2, PAPSS2, STAB2) were identified in over one-third of the TS patients. In contrast, we identified only seven variants in known thrombosis genes (including FV Leiden). CONCLUSIONS: As CS has multiple functions in the glycocalyx protecting the endothelial cells, reduced availability of CS could diminish the normal control mechanisms for blood coagulation, making these CS metabolism genes strong potential risk factors for TS. Overall, no single gene was identified with strong evidence for TS causality; however, our data suggest TS is mediated by an accumulation of rare pro thrombotic risk factors. PMID- 29178991 TI - The disseminated intravascular coagulation score is a novel predictor for portal vein thrombosis in cirrhotic patients with hepatitis B. AB - BACKGROUND: The development of portal vein thrombosis (PVT) in cirrhotic patients has not been fully elucidated. The disseminated intravascular coagulation (DIC) score, which is based on readily available and relatively inexpensive coagulation parameters, including platelet count, fibrin-related markers, prothrombin time and fibrinogen, has not been reported regarding PVT development in cirrhotic patients to date. We aimed to evaluate the prognostic value of the DIC score in predicting PVT development in cirrhotic patients with hepatitis B. MATERIAL AND METHODS: A total of 109 cirrhotic patients with hepatitis B were included. Clinical data, laboratory tests and imaging were collected from the patients at baseline and every three months after enrollment. All patients were followed until the study endpoint (either occurrence of PVT or 12months after baseline). We measured routine laboratory parameters and conducted imaging examinations in cirrhotic patients and evaluated the prognostic value of the DIC score as a novel predictor for PVT in patients with cirrhosis. We also compared the effectiveness of the DIC score with other common coagulation and hemodynamic parameters. RESULTS: Among the 109 patients, 14 (12.8%) developed PVT. At the study endpoint, significant increases in D-dimer, Child-Pugh score and DIC score (all P<0.001) and significantly reduced portal flow velocity (P<0.001) were noted in the PVT group. Among the selected factors, the DIC score had the largest area under the curve (AUC) (0.845), followed by the Child-Pugh score (0.778), D-dimer (0.732), and portal vein velocity (0.709). CONCLUSION: Among the selected factors, the DIC score showed non-significantly higher diagnostic performance in predicting the PVT development in cirrhotic patients compared with other factors. A validation cohort of the study is needed in the near future. PMID- 29178992 TI - Toxicological responses of Laeonereis acuta (Polychaeta, Nereididae) after acute, subchronic and chronic exposure to cadmium. AB - The objective of this study was to analyze the toxicological responses of the estuarine polychaete Laeonereis acuta after acute (96h), subchronic (7 days) and chronic (14 days) exposure to cadmium (Cd). Concentrations of metallothioneins (MT), lipid peroxidation (LPO), total Cd and metal-rich granules (MRG) were evaluated. Seasonal variations of MT and LPO levels in the wild were also measured. Polychaetes were obtained in the Quequen estuary located southeast of Buenos Aires Province, Argentina. For the acute toxicity assay, individuals were exposed to 10; 30, 65; 310; 600; 1300; 2000; 4300; 8100; 16300ugCdL-1, which included levels of environmental relevance and median lethal concentrations (LC50) for related species of polychaete. Based on 96h LC50 values, polychaetes were exposed to sublethal doses of Cd. The concentrations for both subchronic and chronic assays were: 10; 30; 65; 310; 600; 1300; 2000; 4300ugCdL-1. The 96h LC50 value was 8234.9ugL-1, which was within the values reported for other species of polychaete, indicating a high tolerance to Cd. MT induction was not observed for any time exposure. In additoin, LPO levels showed no differences with respect to control levels, which indicated an absence of oxidative damage caused by Cd. However, the total Cd and MRG-Cd concentrations in L. acuta in all tested treatments showed significant differences with respect to control levels. L. acuta were able to accumulate Cd in their tissues in the form of granules which are the main mechanism of Cd detoxification.

AB - A rapid and simple chemical synthesis of poly(2-aminothiophenol)-silver (P2ATP Ag) nanocomposite using conductive and electroactive silver nanoparticles (AgNPs) is reported. The AgNPs was synthesized by chemical reduction method using tri sodium citrate as reducing agent and poly(N-vinyl-2-pyrrolidone) (PVP) as stabilizing agent. P2ATP-Ag nanocomposite was synthesized by using potassium peroxodisulphate as oxidant and the samples were characterized. The presence of AgNPs in the composite was confirmed from UV-Vis, FTIR and X-ray diffraction studies. Morphology of the P2ATP and its composite were investigated by SEM. HR TEM images show spherical, trigonal and rod like morphologies with sizes of Ag nanoparticles and its composite. Thermal analysis revealed that the thermal stability of the P2ATP-Ag nanocomposite is improved when compared with pure P2ATP. The synthesized AgNPs, pure P2ATP and P2ATP-Ag nanocomposite were screened for antibacterial activity test against human pathogen such as Gram positive (Bacillus subtilis, ATCC-6051) and Gram negative (Vibrio cholerae, ATCC-14035), carried out by agar-well diffusion method at micro molar concentration. The result shows that P2ATP-Ag nanocomposite has excellent antibacterial activity due to the presence of Ag nanoparticles. The electrical conductivity of the P2ATP-Ag nanocomposite is better than that of pure P2ATP. The reported nanocomposite will be a potential material for electrocatalysis, sensors and biomedical applications. PMID- 29178994 TI - Green synthesis of highly fluorescent nitrogen - Doped carbon dots from Lantana camara berries for effective detection of lead(II) and bioimaging. AB - Here, we developed a simple green approach for the synthesis of highly fluorescent nitrogen doped carbon dots (NCDs) using Lantana camara berries. Optical and physicochemical properties of as synthesized NCDs were extensively studied by using various analytical techniques. NCDs exhibited bright fluorescence with Quantum yield as high as 33.15%, which is stable to various effects like heat, pH, ionic strength and continuous irradiation. Furthermore, the NCDs presented highly selective and sensitive fluorescence response towards Pb2+ which explored their potential to serve as a label-free fluorescent probe for the effective detection of Pb2+. As developed NCDs based probe exhibited a great linear response (R2=0.998) towards Pb2+ in the concentration range of 0 200nM with a detection limit of 9.64nM. The probe further presented high precision without any interference and was successfully applied for the detection of Pb2+ in the real water and human sera (serum and urine) samples. Cytotoxicity studies on both cancerous (human breast adenocarcinoma MCF-7) and normal (Human embryonic kidney HEK-293) cell lines revealed their excellent biocompatibility. With their low cytotoxicity, strong fluorescence and excitation-dependent emission, NCDs were successfully applied as multi-colour bioimaging agents and Pb2+ detection capabilities were further evaluated in live cells. PMID- 29178995 TI - A new insight into the interaction of ZnO with calf thymus DNA through surface defects. AB - Experimental evidences on the binding interaction of ZnO and Calf Thymus (CT) DNA using several biophysical techniques are the centre of interest of the present study. The interaction of ZnO with CT DNA has been investigated in detail by absorption spectral study, fluorescence titration, Raman analysis, zeta potential measurement, viscometric experiment along with thermal melting study and microscopic analysis. Steady-state fluorescence study revealed the quenching (48%) of the surface defect related peak intensity of ZnO on interaction with DNA. The optimized concentration of ZnO and DNA to obtain this level of quenching has been found to be 0.049mM and 1.027MUM, respectively. Additional fluorescence study with 8-hydroxy-5-quinoline (HQ) as a fluorescence probe for Zn2+ ruled out the dissolution effect of ZnO under the experimental conditions. DNA conjugation on the surface of ZnO was also supported by Raman study. The quantitative variation in conductivity as well as electrophoretic mobility indicated significant interaction of ZnO with the DNA molecule. Circular dichroism (CD) and viscometry titrations provided clear evidence in support of the conformational retention of the DNA on interaction with ZnO. The binding interaction was found to be predominantly entropy driven in nature. The bio-physical studies presented in this paper exploring ZnO-CT DNA interaction could add a new horizon to understand the interaction between metal oxide and DNA.

AB - This study aims to evaluate, in vitro, the effect of Aloe vera associated with endodontic medication, with or without laser photobiomodulation (FTL) irradiation in FP6 human pulp fibroblasts. The materials were divided into eight groups: CTR control; CL - FTL alone; AA - Aloe vera with distilled water; AL - Aloe vera with distilled water and FTL; HA - calcium hydroxide P.A. with distilled water; HL - calcium hydroxide P.A. with distilled water and FTL; HAA - calcium hydroxide P.A. with Aloe vera and distilled water; HAL - calcium hydroxide P.A. with Aloe vera, distilled water, and FTL. The cytotoxicity was evaluated by MTT assay at 24, 48, and 72h and the genotoxicity by micronucleus test assay. This study was performed in triplicate. Data obtained in both tests were statistically analyzed by ANOVA and Tukey's tests (p<=0.05). Group AA presented high genotoxicity and low cytotoxicity. After 24, 48, and 72h, the group HAA significantly reduced the cell viability. Interaction with FTL showed slightly increase cell viability after 24 and 48h in groups CL and HL (p<0.001), despite the high genotoxicity in group CL and low genotoxicity in group HL. Group AL showed higher cell survival rate at 72h (p<0.05) and high genotoxicity (p<0.001). It was concluded that Aloe vera allowed higher cell viability in human pulp fibroblasts in the presence of calcium hydroxide or with FTL separately, but genotoxicity increased in these associations.

This assumption is highly relevant for the vulnerable population of low academic achievers because their academic performance might benefit from enhanced physical fitness. The current study examined whether physical fitness and executive functioning are independent predictors of low mathematics and spelling achievement or whether the relation between physical fitness and low achievement is mediated by specific executive functions. In total, 477 students from second- and third-grade classes of 12 primary schools were classified as either low or average-to-high achievers in mathematics and spelling based on their scores on standardized achievement tests. Multilevel structural equation models were built with direct paths between physical fitness and academic achievement and added indirect paths via components of executive functioning: inhibition, verbal working memory, visuospatial working memory, and shifting. Physical fitness was only indirectly related to low achievement via specific executive functions, depending on the academic domain involved. Verbal working memory was a mediator between physical fitness and low achievement in both domains, whereas visuospatial working memory had a mediating role only in mathematics. Physical fitness interventions aiming to improve low academic achievement, thus, could potentially be successful. The mediating effect of executive functioning suggests that these improvements in academic achievement will be preceded by enhanced executive functions, either verbal working memory (in spelling) or both verbal and visuospatial working memory (in mathematics).

AB - Rodent decision-making research aims to uncover the neural circuitry underlying the ability to evaluate alternatives and select appropriate actions. Designing behavioral paradigms that provide a solid foundation to ask questions about decision-making computations and mechanisms is a difficult and often underestimated challenge. Here, we propose three dimensions on which we can consider rodent decision-making tasks: ethological validity, task complexity, and stimulus-response compatibility. We review recent research through this lens, and provide practical guidance for researchers in the decision-making field. PMID- 29179007 TI - Electron microscopy observations on testis and spermatozoa of Leptodactylus chaquensis (Anura, Leptodactylidae). AB - Scanning and transmission electron microscopy were used to investigate the fine structure of the testis and spermatozoa of toad Leptodactylus chaquensis. Our observations indicate that germinal compartment contains Sertoli (SC) and germ cells. The tight junctions and desmosomes among SC indicate the existence of an hematotesticular barrier in charge of maintaining the differences in the composition of the germinal and interstitial compartments. During spermatogenesis, SC acts as a structural support for germ cells. Secondary spermatogonias, spermatocytes and spermatids are joined by cytoplasmic bridges that allow communication between cells in the same cyst. Spermatids at the subcellular level two well-defined morphological stages can be observed: primary spermatids are rounded cells with an acrosomal vesicle attached to the nucleus which has a diameter of about 4.39+/-0.36MUm. Secondary spermatids are elongated with a nucleus of about 19.50+/-0.92MUm in diameter and the acrosome and the axoneme are located in opposite poles of the cells. At the apical end of the spermatozoon we can observe a large arrowhead-shaped acrosome (6.26+/-0.28MUm in length) that takes up about one third of the gamete head with 17.33+/-0.29MUm in length. The proximal centriole is located in the nuclear fossa while the distal centriole gives rise to the flagellar axoneme. The flagellum exhibits a typical pattern of "9+2" and adjacent to it is the axial fiber, and an undulating membrane stretches between both structures. Transmission electron microscopy observations allowed us to produce a diagram of the structure of the spermatozoon of L. chaquensis. Leydig cells, located in the interstitial compartment, show scarce cytoplasm, mitochondria and large-sized lipid droplets which would provide the raw matter for the synthesis of steroid hormones. PMID- 29179008 TI - Oblique illumination in microscopy: A quantitative evaluation. AB - Many biological objects are barely distinguished with the brightfield microscope because they appear transparent, translucent and colourless. One simple way to make such specimens visible without compromising contrast and resolution is by controlling the amount and the directionality of the illumination light. Oblique illumination is an old technique described by many scientists and microscopists that however has been largely neglected in favour of other alternative methods. Oblique lighting (OL) is created by illuminating the sample by only a portion of the light coming from the condenser. If properly used it can improve the resolution and contrast of transparent specimens such as diatoms. In this paper a quantitative evaluation of OL in brigthfield microscopy is presented. Several feature descriptors were selected for characterising contrast and sharpness showing that in general OL provides better performance for distinguishing minute details compared to other lighting modalities. Oblique lighting is capable to produce directionally shadowed differential contrast images allowing to observe phase details in a similar way to differential contrast images (DIC) but at lower cost. The main advantage of OL is that the resolution of the light microscope can be increased by effectively doubling the angular aperture. OL appears as a cost effective technique both for the amateur and professional scientist that can be used as a replacement of DIC or phase contrast when resources are scarce.

AB - INTRODUCTION: The surfaces of endoosseous dental implants have been subjected to numerous modifications in order to create a surface which can provide rapid bone healing and fast implant loading. Each modification has involved changes to the chemical composition and topography of the surfaces which have resulted in various biological reactions to the implanted material. AIM: The aim of this study was to evaluate the surface topography and chemistry of various modified titanium surfaces: (1) machined surface (MA), (2) alumina-blasted (Al2O3), (3) alumina-blasted and acid-etched (Al2O3 DE), (4) hydroxyapatite/tricalcium phosphate grit-blasted (HA/TCP) and (5) hydroxyapatite/tricalcium phosphate grit blasted and acid-etched (HA/TCP DE) and to analyse the effects of surface roughness, and chemical composition on human osteoblast vitality, differentiation, morphology and orientation. MATERIALS AND METHODS: The modified surfaces were subjected to topographic analysis using Scanning Electron Microscopy (SEM), optical profilometry, roughness analysis and chemical composition evaluation using Energy Dispersion Spectroscopy (EDS) analysis. The biological effects of the titanium modifications was analysed using human osteoblasts cell culture where the cell morphology, vitality (MTS assay) and differentiation (ALP activity) was analysed. RESULTS: The machined surfaces were classified as anisotropic, smooth and composed of titanium and oxygen. The blasted surface samples along with the blasted and etched samples were found to be isotropic and rough. The grit-blasting procedure resulted in the incorporation of components from the blasting material. In the case of the blasted and etched samples, etching decreased the surface development as indicated by the Sdr and also reduced the amount of chemical compounds incorporated into the surfaces during the blasting procedure. The attached NHOst cells, proliferated the surfaces. With regard to the MA samples, the cells spread close to the titanium surface, with expanded cytoplasmic extensions and lamelipodia and were oriented in line with the groves left after machining. On the rough substrates, cells were less dispersed and exhibited numerous cytoplasmic extensions, filopodia and interconnections, they were not oriented with respect to the surfaces features. The cell viability of all samples except for Al2O3 decreased after the first day of culture. For all Al2O3, Al2O3 DE and HA samples the viability increased with culture time after an initial reduction. At the end of the culture period the ALP activity was slightly greater on Al2O3 and HA samples compared to the control with the HA DE sample having the same activity as the control. The Al2O3, HA and HA DE ALP samples showed comparable activity and were statistically different from MA and Al2O3 DE samples. CONCLUSIONS: In this study, variously treated titanium surfaces were correlated with osteoblastic cell viability, morphology and differentiation in comparison with the plastic and smooth titanium. All examined surfaces were found to be biocompatible. Favourable cell reactions were observed for Al2O3 and HA blasted surfaces. The surface roughness patterns influenced the growth orientation while the surface topography influenced osteoblast morphology. Further animal studies are necessary to compare the in vivo effect on osseointegration of these modified titanium surfaces. PMID- 29179010 TI - Method for estimating modulation transfer function from sample images. AB - The modulation transfer function (MTF) represents the frequency domain response of imaging modalities. Here, we report a method for estimating the MTF from sample images. Test images were generated from a number of images, including those taken with an electron microscope and with an observation satellite. These original images were convolved with point spread functions (PSFs) including those of circular apertures. The resultant test images were subjected to a Fourier transformation. The logarithm of the squared norm of the Fourier transform was plotted against the squared distance from the origin. Linear correlations were observed in the logarithmic plots, indicating that the PSF of the test images can be approximated with a Gaussian. The MTF was then calculated from the Gaussian approximated PSF. The obtained MTF closely coincided with the MTF predicted from the original PSF. The MTF of an x-ray microtomographic section of a fly brain was also estimated with this method. The obtained MTF showed good agreement with the MTF determined from an edge profile of an aluminum test object. We suggest that this approach is an alternative way of estimating the MTF, independently of the image type. PMID- 29179011 TI - IVF outcome in azoospermic cancer survivors. AB - OBJECTIVE: To assess clinical outcome among infertile couples treated by in vitro fertilization (IVF) and intra cytoplasmic sperm injection (ICSI) using testicular sperm from azoospermic cancer survivors. STUDY DESIGN: This clinical retrospective study included infertile couples treated in a single tertiary referral center between 1996 and 2013. All male partners were cancer survivors who were diagnosed with azoospermia due to previous gonadotoxic treatments and referred to testicular sperm extraction (TESE). Retrieved sperm was used for IVF ICSI among patients' spouses. Sperm retrieval rate and IVF-ICSI outcome were evaluated. RESULTS: Sperm was successfully retrieved in 12 out of 36 patients (33.3%) on initial TESE, with an overall sperm retrieval rate of 38.6% (17 of 44). Female patients were 29.8+/-5.1 years old. The average number of retrieved oocytes was 14.0+/-4.0 per cycle, with clinical pregnancy and live birth rates per successful TESE of 64% (11 of 17) and 58.8% (10 of 17), respectively. Age, serum FSH, testicular volume and time from chemotherapy to TESE were not significantly different between patients with successful TESE to those without. Patients suffering from seminomas had significantly higher sperm retrieval rate, as compared to patients who had Hodgkin's lymphoma (P=0.024). CONCLUSIONS: Post chemotherapy azoospermia can be successfully treated with TESE and ICSI, and should be offered to azoospermic cancer survivors who did not cryopreserve sperm prior to their gonadotoxic treatments. PMID- 29179012 TI - Reproducibility of the transvaginal sonographic assessment of bladder wall thickness. AB - OBJECTIVE: To assess whether transvaginal sonographic measurements of bladder wall thickness (BWT) have adequate reproducibility to detect differences in BWT potentially indicative of detrusor overactivity in women with overactive bladder. STUDY DESIGN: Three reproducibility studies were undertaken to assess (A) total measurement error, (B) intra-observer variability and (C) inter-observer measurement in the interpretation of scans. Women recruited to the Bladder Ultrasound Study underwent a transvaginal ultrasound scan to obtain a measurement of BWT. When a second observer was available, women who agreed to have two transvaginal scans by different operators were recruited into study A. For study B the first observer reassessed a sample of the recorded images at a later date whilst for study C, a random selection of BWT images were read by a second assessor. Analytical variability, percentage of variability attributable to measurement error, within-person variation and the smallest real difference detectable were estimated. RESULTS: One hundred and twenty-one women took part: 27 had repeat scans, 37 had scans re-read by the same observer, and 57 had scans read by two observers. In study A, 39% of the total variability in measurements was explained by measurement error (the remainder to within person change); the standard deviation (SD) of measurement error was 0.76mm and the smallest detectable clinical difference was 2.1mm. The SD of measurement error from scan interpretation was 0.42mm within observers (study B) and 0.35mm between observers (studyC). CONCLUSION: The high levels of measurement error for a small measurement of BWT means it is unlikely Transvaginal ultrasound measurements have insufficient reliability and reproducibility to be an accurate diagnostic test. PMID- 29179013 TI - Increased systemic microbial translocation is associated with depression during early pregnancy. AB - Plasma level of microbial translocation is a marker of mucosal permeability. Increased mucosal permeability ignites elevated microbial translocation and as a consequence of systemic inflammation. Pregnant women with depression have higher levels of inflammatory markers relative to pregnant women without depression, however, no studies have reported whether systemic microbial translocation will change in depressed women during pregnancy. In this study, we examined the plasma LPS level of depressed women during pregnancy. The results showed that the plasma LPS level was significantly increased in depressed mothers during their 8-12 weeks gestation compared to healthy controls. Compared to 8-12 weeks gestation, the plasma LPS levels were significantly decreased at 24-28 weeks gestation and 6 8 weeks postpartum in both depressed subjects and healthy controls. Furthermore, the plasma levels of pro-inflammatory cytokines (TNF-alpha and MCP/CCL2) associated with microbial translocation were significantly increased in depressed subjects during 8-12 weeks gestation compared to healthy controls. These results indicate that the level of microbial translocation is increased in depressed women during early pregnancy. PMID- 29179014 TI - Clinical utility of biomarkers of the hand in the diagnosis of schizophrenia. AB - A number of biomarkers were assessed in photos and prints of the hands of 95 patients with a variety of mental disorders to determine whether patients with schizophrenia could be distinguished from the others. Patients were recruited as consecutive admissions from an outpatient psychiatric day hospital population. Fourteen patients were diagnosed with schizophrenia/schizoaffective disorder and 81 were diagnosed with other mental disorders. A discriminant analysis yielded an overall 80% correct classification, with a sensitivity (schizophrenia patients identified correctly) of 78.6% and a specificity (non-schizophrenia patients identified correctly) of 80.2%. Significant differences were noted in the proximal interphalangeal joint, eponychium of the middle digit and fingernails. To determine biomarker frequency distribution patients with bipolar disorder were then compared to those with schizophrenia/schizoaffective disorder and then to patients with PTSD. The former yielded an overall 78.6% correct classification, with a sensitivity of 71.4% and a specificity of 85.7% and with similar biomarker frequency distribution for bipolar disorder as for the entire non schizophrenia group. The latter comparison yielded an overall 58.6% correct classification, with no significant differences between the features. The application of these biomarkers in clinical practice could constitute an additional tool for the psychiatrist in cases lacking diagnostic clarity. PMID- 29179015 TI - Serum levels of interleukins IL-6 and IL-10 in individuals with posttraumatic stress disorder in a population-based sample. AB - To evaluate the serum levels of IL-6 and IL-10 anti-inflammatory interleukins in individuals with post-traumatic stress disorder (PTSD) in a population-based study. This is a paired study nested in a cross-sectional population-based study. All individuals who presented PTSD and did not present major depressive disorder, diagnostic by interview--Mini International Neuropsychiatric Interview were selected. From these, 41 healthy controls were matched by sex and age. Serum levels of IL-6 and IL-10 were measured by the ELISA, using commercial kits. The group of individuals with PTSD showed a significant increase in the serum levels of IL-6 and IL-10. Our results suggest that individuals with PTSD may present an activation of the immune system, which may lead to neuroinflammation. PMID- 29179016 TI - Group family-based cognitive behavioral therapy for pediatric obsessive compulsive disorder: Global outcomes and predictors of improvement. AB - This open, uncontrolled study examined the efficacy of a group family-based cognitive behavioral therapy (GF-CBT) protocol in treating pediatric obsessive compulsive disorder (OCD) and explored predictors of symptom improvement. Eighty five OCD-affected youth aged 8-18 years (M = 13.9 years, SD = 2.49; 46% male) and their parent(s) participated in a weekly, 12-session GF-CBT program. Data from multiple perspectives were gathered at the beginning and end of treatment, as well as at one-month follow-up. A broad range of assessment measures were utilized to capture clinically-relevant domains and a number of potential predictor variables were explored. Paired t-tests indicated that treatment was associated with significant reductions in clinician- and parent-rated OCD severity (d = 1.47, 1.32), youth and parent-rated functional impairment (d = 0.87, 0.67), coercive/disruptive behaviors (d = 0.75), and family accommodation (d = 1.02), as well as improvements in youth-, mother-, and father-rated family functioning (d = 1.05, 0.50, 0.88). Paired t-tests also indicated that youth remained improved at one-month follow-up. Step-wise regression identified greater homework success as a significant predictor of symptom improvement. This study provides evidence that GF-CBT significantly improves a wide range of domains for youth/families that extends beyond OCD symptom severity and supports homework as a core treatment component. PMID- 29179017 TI - Intimate partner violence and disordered eating among male and female veterans. AB - Intimate partner violence (IPV) affects many women and men in the United States and has been associated with numerous mental health conditions, including disordered eating (DE). Veterans may be especially vulnerable to experiencing both of these serious problems given the unique aspects and stressors relevant to military culture, including high rates of trauma exposure. We aimed to estimate the prevalence of past-year IPV among independent samples of male (N = 642) and female (N = 198) veterans and to examine the association between past-year IPV and DE. Mplus 7.0 was used to estimate associations between multiple types of IPV and DE, controlling for age, body mass index, military sexual trauma, and other military trauma. Approximately 14.86% of male veterans and 12.79% of female veterans reported experiencing some form of past-year IPV. All forms of past-year IPV, including physical, sexual, and psychological/emotional, were significantly associated with DE in both samples, after adjusting for covariates. IPV was relatively common among male and female veterans, and those who experience IPV may be particularly vulnerable to DE. Findings extend the knowledge base regarding IPV and its health effects among an understudied population, and may be a catalyst for further research and clinical inquiry to target improving psychiatric care for male and female veterans who experience IPV. PMID- 29179018 TI - Analytic processing of distance. AB - How does a human observer extract from the distance between two frontal points the component corresponding to an axis of a rectangular reference frame? To find out we had participants classify pairs of small circles, varying on the horizontal and vertical axes of a computer screen, in terms of the horizontal distance between them. A response signal controlled response time. The error rate depended on the irrelevant vertical as well as the relevant horizontal distance between the test circles with the relevant distance effect being larger than the irrelevant distance effect. The results implied that the horizontal distance between the test circles was imperfectly extracted from the overall distance between them. The results supported an account, derived from the Exemplar Based Random Walk model (Nosofsky & Palmieri, 1997), under which distance classification is based on the overall distance between the test circles, with relevant distance being extracted from overall distance to the extent that the relevant and irrelevant axes are differentially weighted so as to reduce the contribution of irrelevant distance to overall distance. The results did not support an account, derived from the General Recognition Theory (Ashby & Maddox, 1994), under which distance classification is based on the relevant distance between the test circles, with the irrelevant distance effect arising because a test circle's perceived location on the relevant axis depends on its location on the irrelevant axis, and with relevant distance being extracted from overall distance to the extent that this dependency is absent. PMID- 29179019 TI - Specific and non-specific match effects in negative priming. AB - The negative priming effect occurs when withholding a response to a stimulus impairs generation of subsequent responding to a same or a related stimulus. Our goal was to use the negative priming procedure to obtain insights about the memory representations generated by ignoring vs. attending/responding to a prime stimulus. Across three experiments we observed that ignoring a prime stimulus tends to generate higher identity-independent, non-specific repetition effects, owing to an overlap in the coarse perceptual form of a prime distractor and a probe target. By contrast, attended repetition effects generate predominantly identity-specific sources of facilitation. We use these findings to advocate for using laboratory phenomena to illustrate general principles that can be of practical use to non-specialists. In the case of the negative priming procedure, we propose that the procedure provides a useful means for investigating attention/memory interactions, even if the specific cause (or causes) of negative priming effects remain unresolved. PMID- 29179020 TI - Different patterns of modality dominance across development. AB - The present study sought to better understand how children, young adults, and older adults attend and respond to multisensory information. In Experiment 1, young adults were presented with two spoken words, two pictures, or two word picture pairings and they had to determine if the two stimuli/pairings were exactly the same or different. Pairing the words and pictures together slowed down visual but not auditory response times and delayed the latency of first fixations, both of which are consistent with a proposed mechanism underlying auditory dominance. Experiment 2 examined the development of modality dominance in children, young adults, and older adults. Cross-modal presentation attenuated visual accuracy and slowed down visual response times in children, whereas older adults showed the opposite pattern, with cross-modal presentation attenuating auditory accuracy and slowing down auditory response times. Cross-modal presentation also delayed first fixations in children and young adults. Mechanisms underlying modality dominance and multisensory processing are discussed. PMID- 29179021 TI - How social information affects information search and choice in probabilistic inferences. AB - When making decisions, people are often exposed to relevant information stemming from qualitatively different sources. For instance, when making a choice between two alternatives people can rely on the advice of other people (i.e., social information) or search for factual information about the alternatives (i.e., non social information). Prior research in categorization has shown that social information is given special attention when both social and non-social information is available, even when the social information has no additional informational value. The goal of the current work is to investigate whether framing information as social or non-social also influences information search and choice in probabilistic inferences. In a first study, we found that framing cues (i.e., the information used to make a decision) with medium validity as social increased the probability that they were searched for compared to a task where the same cues were framed as non-social information, but did not change the strategy people relied on. A second and a third study showed that framing a cue with high validity as social information facilitated learning to rely on a non compensatory decision strategy. Overall, the results suggest that social in comparison to non-social information is given more attention and is learned faster than non-social information. PMID- 29179022 TI - Re-engineering of protein motors to understand mechanisms biasing random motion and generating collective dynamics. AB - A considerable amount of insight into the mechanisms of protein-based biomolecular motors has been accumulated over decades of research. However, our knowledge about the design principles of these motors is still limited. Even less is known about the design of multi-motor systems that perform various functions within the cell. Here we focus on constructive (or synthetic) approaches to biomolecular motors that could make a breakthrough in our understanding. Recent achievements include studies at different hierarchical levels of complexity: re engineering of individual motors, construction of multi-motor systems, and generation of large-scale complex behaviour. We then propose a strategy where the collective behaviour can be repeatedly tested upon modifying individual motors, which may provide important clues about how biomolecular motors and their systems are designed. PMID- 29179023 TI - Validation of a low field Rheo-NMR instrument and application to shear-induced migration of suspended non-colloidal particles in Couette flow. AB - Nuclear magnetic resonance rheology (Rheo-NMR) is a valuable tool for studying the transport of suspended non-colloidal particles, important in many commercial processes. The Rheo-NMR imaging technique directly and quantitatively measures fluid displacement as a function of radial position. However, the high field magnets typically used in these experiments are unsuitable for the industrial environment and significantly hinder the measurement of shear stress. We introduce a low field Rheo-NMR instrument (1H resonance frequency of 10.7MHz), which is portable and suitable as a process monitoring tool. This system is applied to the measurement of steady-state velocity profiles of a Newtonian carrier fluid suspending neutrally-buoyant non-colloidal particles at a range of concentrations. The large particle size (diameter >200MUm) in the system studied requires a wide-gap Couette geometry and the local rheology was expected to be controlled by shear-induced particle migration. The low-field results are validated against high field Rheo-NMR measurements of consistent samples at matched shear rates. Additionally, it is demonstrated that existing models for particle migration fail to adequately describe the solid volume fractions measured in these systems, highlighting the need for improvement. The low field implementation of Rheo-NMR is complementary to shear stress rheology, such that the two techniques could be combined in a single instrument. PMID- 29179024 TI - Effects of brief mindfulness and loving-kindness meditation inductions on emotional and behavioral responses to social rejection among individuals with high borderline personality traits. AB - Borderline personality disorder (BPD) is characterized by an enduring pattern of instability across affective, behavioral, cognitive, and interpersonal domains. Individuals with BPD are known to be particularly vulnerable to experiences of social rejection, but little work has examined strategies that may moderate their reactivity to social rejection. Using a laboratory experimental approach, this study investigated the effects of brief mindfulness and loving-kindness meditation (LKM) inductions on emotional and behavioral responses to social rejection in a sample of adults with high BPD traits. One hundred and eighteen participants were randomly assigned to receive 10 min of mindful breathing practice, LKM, or a no-instruction control condition, prior to exposure to a social rejection manipulation. Participants rated their emotions and completed a competitive reaction time task, which provided a proxy measure of aggression. Compared to the control condition, the mindfulness group demonstrated significantly quicker recovery in negative affect and feelings of rejection after social rejection. The mindfulness group also reported significantly quicker recovery in negative affect compared to the LKM group. Whereas baseline trait mindfulness negatively predicted aggressive behaviors across all participants, groups did not differ in immediate emotional reactivity or aggressive behavior following social rejection. The findings suggest that mindfulness training may be a promising strategy in alleviating negative emotional effects of social rejection among individuals with high borderline personality traits, and highlight the limited utility of brief LKM practice in buffering the effects of social rejection. PMID- 29179025 TI - Heterogeneity in the impact of type of schooling on adult health and lifestyle. AB - Using data from a major educational reform in England and Wales, we examine heterogeneity in the long-term impacts of the exposure to different secondary schooling systems, characterized by selective early-tracking system versus non selective comprehensive schooling, on health outcomes and smoking. We adopt a local instrumental variables approach to estimate person-centered treatment (PeT) effects, thereby recovering the full distribution of individual-level causal effects. We find that the transition from a selective early-tracking system to a non-selective one produced, on a fraction of individuals, significantly increased depression and cigarette smoking. These effects were persistent over time. Cognitive abilities did not moderate the effects, but students with lower non cognitive skills were most likely to be negatively affected by this exposure. PMID- 29179026 TI - Is retirement good for men's health? Evidence using a change in the retirement age in Israel. AB - This study examines the effect of employment on elderly men's health. A typical OLS analysis yields a positive relationship between employment and health for individuals in their sixties. Causality, however, is difficult to infer because healthier individuals are more capable of working than others. To overcome this endogeneity problem, this paper exploits the increase in the full retirement age for men in Israel from sixty-five to sixty-seven in 2004. After this change, the employment rate of men in this age bracket jumped significantly compared to the last cohort that was able to retire at sixty-five. Using the new retirement law as an exogenous source of variation in the employment status of elderly men, a significant causal relationship in the opposite direction of the correlation is found: employment at older ages impairs health. These findings are found across a broad array of datasets and health outcomes. The results are significantly stronger among less-educated workers, suggesting that employment in physically demanding occupations is more detrimental to health. Placebo analyses using the years preceding the new retirement regime and other health measures unrelated to employment (e.g., dentist visits) reinforce a causal interpretation of my main findings. PMID- 29179027 TI - The effect of smoking on obesity: Evidence from a randomized trial. AB - This paper aims to identify the causal effect of smoking on body mass index (BMI) using data from the Lung Health Study, a randomized trial of smoking cessation treatments. Since nicotine is a metabolic stimulant and appetite suppressant, quitting or reducing smoking could lead to weight gain. Using randomized treatment assignment to instrument for smoking, we estimate that quitting smoking leads to an average long-run weight gain of 1.8-1.9 BMI units, or 11-12 pounds at the average height. Semi-parametric models provide evidence of a diminishing marginal effect of smoking on BMI, while subsample regressions show that the impact is largest for younger individuals, those with no college degree, and those in the lowest quartile of baseline BMI. PMID- 29179028 TI - Kinematic analysis of scapular movements in patients with facioscapulohumeral muscular dystrophy. AB - The purpose of this study is to evaluate scapular movements by the three dimensional electromagnetic system during shoulder elevation in FSHMD patients, and to compare the results with healthy individuals. 10 patients with FSHMD and 10 healthy individuals were included in the study. Scapular anterior-posterior tilt, upward-downward rotation and internal-external rotation at 30 degrees , 60 degrees and 90 degrees were evaluated using the three-dimensional electromagnetic system during the elevation of the upper limbs in the scapular plane. Humerothoracic elevation levels on the dominant and non-dominant sides were found to be lower in the patients than healthy individuals (p < .001). Both scapula were rotated downwards at 30 degrees (dominant/non-dominant p < .001) and 60 degrees (dominant p = .009, non-dominant p = .04) of humerothoracic elevation, the scapula was rotated internally at 30 degrees of humerothoracic elevation on the non-dominant side (p = .03), and the scapula was tilted posteriorly at 90 degrees of humerothoracic elevation on the non-dominant side (p = .009) in patients. These existing abnormal patterns of the scapula in the patients increase the risk of impairment, pain, impingement and instability especially in the activities that require arm elevation. It is thought that physiotherapy approaches should first be emphasized to improve scapular stabilization and strengthening exercises should then be performed for the shoulder girdle muscles. PMID- 29179029 TI - 3EZ, 20Ac-ingenol induces cell-specific apoptosis in cyclin D1 over-expression through the activation of ATR and downregulation of p-Akt. AB - Acute lymphoblastic leukemia (ALL) samples exhibit an activated PI3K/Akt pathway, which suggests a general role of Akt in the development of leukemia. We have previously used western blot analysis to show that the catalytic topoisomerase (topo) inhibitor, 3EZ, 20Ac-ingenol, induced DNA damage response (DDR), which activated ATR, downregulated p-Akt through upregulation of PTEN level, and led to cell cycle arrest or apoptosis. In this study, we used ATR or PTEN siRNA and observed that the specific cell arrest and apoptosis of BALL-1 cells in DDR caused by 3EZ, 20Ac-ingenol was dependant on activation of ATR and downregulation of nuclear p-Akt through upregulation of PTEN. Moreover, some B cell lymphomas among ALLs overexpress cyclin D1. The DDR induced during the S-phase with 3EZ, 20Ac-ingenol treatment was increased by the intra S-phase checkpoint response that was triggered by the loss of nuclear cyclin D1 regulation in BALL-1 cells overexpressing cyclin D1. Although topo 1 catalytic inhibitors induce a decatenation checkpoint and subsequent G2/M phase arrest, the decatenation checkpoint caused by 3EZ, 20Ac-ingenol induced apoptosis only in the BALL-1 cells that accumulated cyclin D1. PMID- 29179030 TI - Efficacy of species-specific probiotic Pediococcus acidilactici FT28 on blood biochemical profile, carcass traits and physicochemical properties of meat in fattening pigs. AB - The present study investigates the influence of supplementing Pediococcus acidilactici strain FT28 on serum biochemistry, carcass and physicochemical properties of meat in fattening pigs. A total of 36 piglets (28day) were randomly divided into three groups of four replicates of three animals in each. Each group was fed one of the experimental diet as basal diet alone (Control-T0); basal diet supplemented with Pediococcus acidilactici strain FT28 (swine origin probiotic T1) and basal diet supplemented with Lactobacillus acidophilus NCDC-15 (dairy origin probiotic-T2). Increased (P<0.05) level of serum total protein and albumin, and decreased (P<0.05) triglyceride were observed with probiotic supplementation either of swine or dairy origin, compared to control. The level globulin and glucose were higher (P<0.05) in T1 group among the dietary groups. Carcass traits remained unaltered except for the weight of ham, kidney and spleen which were higher (P<0.05) in the T1 group. Water holding capacity and TBARS were improved (P<0.05) in the T1 group than control, however comparable to the T2 group. The ether extract, pH and sensory attributes (juiciness and appearance) were improved (P<0.05) in the T1 group among the dietary groups. It is evident from the present study that P. acidilactici FT28 could serve as probiotic for enhancing carcass quality and physicochemical properties of pork without influencing the blood metabolites. PMID- 29179031 TI - Innate immune responses to metabolic stress can be detected in rumen fluids. AB - Many production diseases of dairy cows are related to digestive troubles. The rumen subacute acidosis is the most relevant one, albeit not easily recognized. Recent studies suggest that forestomachs can perform regulatory actions at both regional and systemic levels, since forestomach walls express immune receptors and cytokines, and the rumen liquor is infiltrated by leukocytes. Therefore, the rumen fluid could be conveniently collected for investigating metabolic production diseases. Thus, we investigated the origin of the leukocytes of the rumen fluid and demonstrated that they partly derive from saliva. Next, we carried out a field survey of innate immunity in rumen fluids of 128 cows from 12 dairy farms, along with clinical inspections, assessment of milk yield, rumen pH, volatile fatty acids (VFA) and major inflammo-metabolic parameters. Significant statistical correlations were found between immune markers in rumen fluids and biochemical parameters. A significant negative correlation was found in rumen between CD45 gene expression (leukocyte infiltration) and pH level. B cells were the most frequent mononuclear leukocyte population in the rumen liquor and their infiltration was negatively affected by low ruminal pH and high concentrations of VFA. Moreover, total Ig and IgM in rumen fluids were negatively correlated with ruminal pH and positively correlated with uremia. Our data suggest that forestomach immune responses could be directed to "dangers" arising within the forestomach environment. The immune markers could integrate consolidated diagnostic parameters (e.g. rumen pH) and contribute to robust, early diagnosis of tricky digestive troubles of cattle.

AB - BACKGROUND: Deficits in muscle volume may be a significant contributor to physical disability in young people with cerebral palsy. However, 3D measurements of muscle volume using MRI or 3D ultrasound may be difficult to make routinely in the clinic. We wished to establish whether accurate estimates of muscle volume could be made from a combination of anatomical cross-sectional area and length measurements in samples of typically developing young people and young people with bilateral cerebral palsy. METHODS: Lower limb MRI scans were obtained from the lower limbs of 21 individuals with cerebral palsy (14.7+/-3years, 17 male) and 23 typically developing individuals (16.8+/-3.3years, 16 male). The volume, length and anatomical cross-sectional area were estimated from six muscles of the left lower limb. FINDINGS: Analysis of Covariance demonstrated that the relationship between the length*cross-sectional area and volume was not significantly different depending on the subject group. Linear regression analysis demonstrated that the product of anatomical cross-sectional area and length bore a strong and significant relationship to the measured muscle volume (R2 values between 0.955 and 0.988) with low standard error of the estimates of 4.8 to 8.9%. INTERPRETATION: This study demonstrates that muscle volume may be estimated accurately in typically developing individuals and individuals with cerebral palsy by a combination of anatomical cross-sectional area and muscle length. 2D ultrasound may be a convenient method of making these measurements routinely in the clinic. PMID- 29179033 TI - Validation of the Arm Profile Score in assessing upper limb functional impairments in people with multiple sclerosis. AB - BACKGROUND: Although upper limb (UL) impairments are widespread in people with Multiple Sclerosis (pwMS), there is limited quantitative evidence concerning their specific features. The aim of this study is to validate a synthetic measure based on kinematic data to define the degree of deviation from a physiologic pattern during the "hand to mouth" (HTM) task. METHODS: Twenty pwMS (mean age 51.2 SD 11.1) years, Expanded Disability Status Scale (EDSS) score in the range 2 6.5, underwent a kinematic analysis of the HTM task using a motion capture system. Spatio-temporal parameters and synthetic indexes (Arm Variable Score, AVS and Arm Profile Score, APS) were calculated and compared with those of age matched healthy individuals. Kinematic data were correlated with the EDSS score and clinical tests such as the Nine Hole Peg Test (NHPT) and hand-grip strength (HGS). FINDINGS: PwMS exhibit reduced velocity, increased movement duration, sway of adjusting and frequency of direction changes as well as higher APS values (15.4 degrees vs. 8.6 degrees , P<0.001) with respect to controls due to alterations in trunk flexion-extension, shoulder abduction-adduction, flexion extension and rotation and elbow flexion-extension. Moderate-to-large correlations were found between APS and EDSS (rho=0.609, P<0.001), NHPT (rho=0.468, P=0.03) and HGS (rho=-0.627 P<0.001). INTERPRETATION: The kinematic analysis of HTM provides useful information in quantifying UL impairments in pwMS. The APS index appears suitable to represent UL movement deviations from the physiological pattern in pwMS and to assess disease progression or effectiveness of pharmacologic and rehabilitative treatments effectiveness.

AB - The expression of p63 in surface ectodermal cells during development of the cornea, skin, oral mucosa and olfactory placodes is integral to the process of cellular self-renewal and the maintenance of the epithelial stem cell status. Here, we used TALEN technology to generate a p63 knock-in (KI) human induced pluripotent stem (hiPS) cell line in which p63 expression can be visualized via enhanced green fluorescent protein (EGFP) expression. The KI-hiPS cells maintained pluripotency and expressed the stem cell marker gene, DeltaNp63alpha. They were also able to successfully differentiate into functional corneal epithelial cells as assessed by p63 expression in reconstructed corneal epithelium. This approach enables the tracing of p63-expressing cell lineages throughout epithelial development, and represents a promising application in the field of stem cell research. PMID- 29179036 TI - Bilateral facial nerve palsies secondary to chronic inflammatory demyelinating polyneuropathy following adalimumab treatment. AB - PURPOSE: Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) presents uncommonly with cranial nerve involvement with ophthalmological implications. METHODS: We report the case of a 37year-old man who developed CIDP which manifested as progressive and relapsing bilateral facial nerve palsy with lagophthalmos and exposure keratopathy, in the setting of treatment of Crohn's disease with the anti-TNF-alpha agent adalimumab. RESULTS: Symptoms gradually improved over the course of several months following withdrawal of adalimumab and treatment with intravenous immunoglobulin (IVIg) and oral prednisolone. CONCLUSION: Bilateral facial nerve involvement occurs uncommonly as a feature of CIDP in its classic form. The prognosis is good for recovery of facial nerve function with discontinuation of anti-TNF-alpha therapy and concurrent use of steroid and intravenous immunoglobulin in this case. PMID- 29179034 TI - Effects of exposure to water disinfection by-products in a swimming pool: A metabolome-wide association study. AB - BACKGROUND: Exposure to disinfection by-products (DBPs) in drinking water and chlorinated swimming pools are associated with adverse health outcomes, but biological mechanisms remain poorly understood. OBJECTIVES: Evaluate short-term changes in metabolic profiles in response to DBP exposure while swimming in a chlorinated pool. MATERIALS AND METHODS: The PISCINA-II study (EXPOsOMICS project) includes 60 volunteers swimming 40min in an indoor pool. Levels of most common DBPs were measured in water and in exhaled breath before and after swimming. Blood samples, collected before and 2h after swimming, were used for metabolic profiling by liquid-chromatography coupled to high-resolution mass spectrometry. Metabolome-wide association between DBP exposures and each metabolic feature was evaluated using multivariate normal (MVN) models. Sensitivity analyses and compound annotation were conducted. RESULTS: Exposure levels of all DBPs in exhaled breath were higher after the experiment. A total of 6,471 metabolic features were detected and 293 features were associated with at least one DBP in exhaled breath following Bonferroni correction. A total of 333 metabolic features were associated to at least one DBP measured in water or urine. Uptake of DBPs and physical activity were strongly correlated and mutual adjustment reduced the number of statistically significant associations. From the 293 features, 20 could be identified corresponding to 13 metabolites including compounds in the tryptophan metabolism pathway. CONCLUSION: Our study identified numerous molecular changes following a swim in a chlorinated pool. While we could not explicitly evaluate which experiment-related factors induced these associations, molecular characterization highlighted metabolic features associated with exposure changes during swimming. PMID- 29179037 TI - Nuclear myosin 1 associates with papillomavirus E2 regulatory protein and influences viral replication. AB - Nuclear myosin 1c (NM1) associates with RNA polymerases and is a partner in the chromatin remodeling complex B-WICH. This complex, which also contains WSTF and SNF2h proteins, is involved in transcriptional regulation. We report herein that papillomavirus protein E2 binds to NM1 and co-precipitates with the WSTF and SNF2h proteins. Our data suggest that E2 associates with the cellular B-WICH complex through binding to NM1. E2 and NM1 associate via their N-terminal domains and this interaction is ATP dependent. The cellular multifunctional protein Brd4 and beta-actin are also present in the NM1-E2 complex. NM1 downregulation by siRNA increases the replication of the BPV1 and HPV5 genomes but does not affect HPV18 genome replication. These results suggest that the B-WICH complex may play a role in the papillomavirus life cycle through NM1 and E2 protein interaction. PMID- 29179038 TI - Molecular evolution and invasion pattern of Cryphonectria hypovirus 1 in Europe: Mutation rate, and selection pressure differ between genome domains. AB - Understanding virus evolution is a fundamental goal of virology, evolutionary biology, and disease epidemiology. We provide a detailed analysis of evolution and origin of Cryphonectria hypovirus 1 (CHV1) populations in Europe, based on the complete genome sequence of all European subtypes. Phylogenetic analyses divided European strains into two closely related clades. Strains of the subtype I belong to the first, while strains of the subtypes F1, D and E belong to the second clade suggesting that the subtypes F1, D and E are more closely related than previously thought. Strains of the subtype F2 appeared to be recombinant; subtypes F1/D/E contributed a larger fraction of sequence while subtype I contributed a smaller fraction. The p29 was the most variable domain, while the replication-associated large ORF B protein was the most conserved domain within the CHV1. Low sequence similarity, predominant negative selection and frequent recombination characterise the evolution of CHV1. PMID- 29179039 TI - Custom Morse taper zirconia abutments: Influence on marginal fit and torque loss before and after thermomechanical cycling. AB - The use of zirconia abutments has increased because of aesthetics, but sometimes customization is necessary and its effect is unclear. This study evaluated the marginal fit and torque loss of customized and non-customized aesthetic zirconia abutments associated with Morse taper implants before and after thermomechanical cycling. Twenty-four implant/abutment/crown sets were divided into three groups (N = 8): Zr - non-customized zirconia abutments, Zrc - customized zirconia abutments, and Ti - titanium abutments. The ceramic crowns of the upper canines were made. All of the abutments were tightened with 15-N.cm torque, and the crowns were cemented on the abutments. The misfits and torque loss were measured before and after thermomechanical cycling. The marginal fit was evaluated in two planes throughout 10 different slices, 30 measurements for each face (i.e., buccal, palatal, mesial and distal) and 120 measurements for each sample. A load of 100N, a frequency of 2Hz and 1000,000 cycles with temperature variation of 5 degrees -55 degrees C were used for thermomechanical cycling. Thermomechanical cycling significantly decreased the marginal misfit only with the Zrc (p = 0.002), and the Ti was significantly different from the Zr and Zrc before and after thermomechanical cycling. Thermomechanical cycling did not affect the torque losses of the groups, but a significant difference between the Zr and Zrc (p = 0.0345) before cycling was noted. Customization of zirconia abutments does not significantly affect torque loss and marginal misfit after thermomechanical cycling suggesting that they can be safe for clinical utilization. PMID- 29179040 TI - Surface integrity and corrosion performance of biomedical magnesium-calcium alloy processed by hybrid dry cutting-finish burnishing. AB - Biodegradable magnesium-calcium (MgCa) alloy is a very attractive orthopedic biomaterial compared to permanent metallic alloys. However, the critical issue is that MgCa alloy corrodes too fast in the human organism. Compared to dry cutting, the synergistic dry cutting-finish burnishing can significantly improve corrosion performance of MgCa0.8 (wt%) alloy by producing a superior surface integrity including good surface finish, high compressive hook-shaped residual stress profile, extended strain hardening in subsurface, and little change of grain size. A FEA model was developed to understand the plastic deformation of MgCa materials during burnishing process. The measured polarization curves, surface micrographs, and element distributions of the corroded surfaces by burnishing show an increasing and uniform corrosion resistance to simulated body fluid. PMID- 29179041 TI - Host-pathogen systems for early drug discovery against tuberculosis. AB - Tuberculosis (TB) is a global disease causing 1.8 million deaths each year. The appearance of drug-resistant strains raised the demand for new anti-mycobacterial drugs and therapies, because previously discovered antibiotics are shown to be inefficient. Moreover, the number of newly discovered drugs is not increasing in proportion to the emergence of drug resistance, which suggests that more optimized methodology and screening procedures are required including the incorporation of in vivo properties of TB infection. A way to improve efficacy of screening approaches is by introducing the use of different host-pathogen systems into primary screenings. These include whole cell-based screenings, zebrafish larvae-based screenings and the impact of artificial granuloma research on the drug discovery process. This review highlights current screening attempts and the identified molecular targets and summarizes findings of alternative, not fully explored host-pathogen systems for the characterization of anti-mycobacterial compounds. PMID- 29179042 TI - Discovery of new RNA classes and global RNA-binding proteins. AB - The identification of new RNA functions and the functional annotation of transcripts in genomes represent exciting yet challenging endeavours of modern biology. Crucial insights into the biological roles of RNA molecules can be gained from the identification of the proteins with which they form specific complexes. Modern interactome techniques permit to profile RNA-protein interactions in a genome-wide manner and identify new RNA classes associated with globally acting RNA-binding proteins. Applied to a variety of organisms, these methods are already revolutionising our understanding of RNA-mediated biological processes. Here, we focus on one such approach-Gradient sequencing or Grad-seq which has recently guided the discovery of protein ProQ and its associated small RNAs as a new domain of post-transcriptional control in bacteria. PMID- 29179043 TI - The effect of exercise intensity on joint power and dynamics in ergometer double poling performed by cross-country skiers. AB - The purpose of this study was to examine the effect of increasing exercise intensity on the role of joint powers in ergometer double poling (DP), while taking specific dynamic constraints into account. One main question was whether lower-body power contribution increased or decreased with increasing intensity. Nine male Norwegian national-level cross-country skiers performed ergometer DP at low, moderate, high and maximal intensity. Kinematics, and ground (GRF) and poling (Fpoling) reaction forces were recorded and used in link segment modeling to obtain joint and whole-body dynamics. Joint powers were averaged over the cycle, the poling (PP) and recovery (RP) phases. The contribution of these average powers was their ratios to cycle average poling power. At all intensities, the shoulder (in PP) and hip (mostly in RP) generated most power. Averaged over the cycle, lower-body contribution (sum of ankle, knee and hip power) increased from ~37% at low to ~54% at maximal intensity (p < .001), originating mostly from increased hip contribution within PP, not RP. The generation of larger Fpoling at higher intensities demanded a reversal of hip and knee moment. This was necessary to appropriately direct the GRF vector as required to balance the moment about center of mass generated by Fpoling (control of angular momentum). This was reflected in that the hip changed from mostly absorbing to generating power in PP at lower and higher intensities, respectively. Our data indicate that power-transfer rather than stretch shortening mechanisms may occur in/between the shoulder and elbow during PP. For the lower extremities, stretch-shortening mechanisms may occur in hip, knee and trunk extensors, ensuring energy conservation or force potentiation during the countermovement-like transition from body lowering to heightening. In DP locomotion, increasing intensity and power output is achieved by increased lower body contribution. This is, at least in ergometer DP, partly due to changes in joint dynamics in how to handle dynamic constraints at different intensities. PMID- 29179045 TI - Reduced recognition and priming in older relative to young adults for incidental and intentional information. AB - Older adults often show greater implicit/unconscious memory than young adults for incidental information that was task-irrelevant during its acquisition. Shallow/perceptual encoding by older adults may boost performance on implicit tasks that reinstate this type of processing, whereas deeper/conceptual encoding by young adults may support greater explicit/conscious memory. To test this, young and older participants were exposed to incidental words in a text color identification task before the trial-by-trial capture of priming and recognition. In Experiments 1-3 priming and recognition were significantly greater in young than older adults, providing evidence against age differences in encoding style. In Experiments 2-3 older adults were more liberal than young adults in making positive recognition judgments to incidental relative to intentional items, even though source memory was poor in both groups. Findings pinpoint age differences in the utilization of previously incidental versus intentional information on different types of task. PMID- 29179044 TI - Nicotine as a discriminative stimulus for ethanol use. AB - Abused drugs reinforce behavior; i.e., they increase the probability of the behavior preceding their administration. Abused drugs can also act as discriminative stimuli; i.e., they can set the occasion for responding reinforced by another event. Thus, one abused drug could come to set the occasion for the use of another and this functional relationship may play a role in polysubstance abuse, where common patterns of use could result in this relationship. Here we establish nicotine (0.4mg/kg, ip 5-min pre-session) as a discriminative stimulus for behavior reinforced by ethanol (0.1ml 8% w/v po, versus food) and determine the ability of nicotine (0.02-0.4mg/kg), varenicline (0.1-3.0mg/kg), and ethanol (250 and 500mg/kg) to control responding for ethanol. We compare these results to those from rats where nicotine signaled food was available (and ethanol was not). Nicotine came to function as a discriminative stimulus. Nicotine and varenicline produced dose-dependent increases in responding on the nicotine-appropriate lever while ethanol produced responding on the vehicle-appropriate lever. Whether this responding occurred on the lever that produced ethanol or food access depended on the training condition. These results demonstrate that a drug can come to set the occasion for use of another and suggest that this behavioral mechanism could play an important role in the maintenance of and recovery from polysubstance abuse, depending on the pattern of use. PMID- 29179046 TI - Enhanced accessibility of ignored neutral and negative items in nonclinical dissociative individuals. AB - While clinical studies showed paradoxical memory phenomena, including the intrusion and amnesia of stressful experiences that are features of dissociation, the results of laboratory studies on dissociative individuals' forgetting of experimental stimuli through cognitive control varied. Some studies demonstrated ineffective inhibition, and others found that dissociative individuals could remember fewer trauma words in a divided-attention context. Dissociative individuals may utilize superior cognitive disengagement to forget the representations. This hypothesis was tested in nonclinical individuals with high, medium, and low dissociation proneness. In the study phase, the participants learned several lists of experimental words and kept updating working memory by remembering the last four items on a list (target) and ignoring those non-target items. A recognition test was then conducted. The high dissociation group performed better on updating working memory. However, the accessibility of the representations of neutral and negative non-target items was elevated. Dissociative individuals disengaged attention effectively from items they intended to ignore, and the representations of the ignored items were more accessible when cues were available. PMID- 29179047 TI - A review of numerical models to predict the atmospheric dispersion of radionuclides. AB - The field of atmospheric dispersion modeling has evolved together with nuclear risk assessment and emergency response systems. Atmospheric concentration and deposition of radionuclides originating from an unintended release provide the basis of dose estimations and countermeasure strategies. To predict the atmospheric dispersion and deposition of radionuclides several numerical models are available coupled with numerical weather prediction (NWP) systems. This work provides a review of the main concepts and different approaches of atmospheric dispersion modeling. Key processes of the atmospheric transport of radionuclides are emission, advection, turbulent diffusion, dry and wet deposition, radioactive decay and other physical and chemical transformations. A wide range of modeling software are available to simulate these processes with different physical assumptions, numerical approaches and implementation. The most appropriate modeling tool for a specific purpose can be selected based on the spatial scale, the complexity of meteorology, land surface and physical and chemical transformations, also considering the available data and computational resource. For most regulatory and operational applications, offline coupled NWP-dispersion systems are used, either with a local scale Gaussian, or a regional to global scale Eulerian or Lagrangian approach. The dispersion model results show large sensitivity on the accuracy of the coupled NWP model, especially through the description of planetary boundary layer turbulence, deep convection and wet deposition. Improvement of dispersion predictions can be achieved by online coupling of mesoscale meteorology and atmospheric transport models. The 2011 Fukushima event was the first large-scale nuclear accident where real-time prognostic dispersion modeling provided decision support. Dozens of dispersion models with different approaches were used for prognostic and retrospective simulations of the Fukushima release. An unknown release rate proved to be the largest factor of uncertainty, underlining the importance of inverse modeling and data assimilation in future developments.

PMID- 29179049 TI - Histological estimation of age at death in amputated lower limbs: Issues of disuse, advanced age, and disease in the analysis of pathological bone. AB - Histological studies of healed bone tissue following amputation are relatively rare in the literature. This study describes the histomorphological features of femoral thin sections from six uni- and bi-lateral amputees of documented age and sex. Thin sections were cut from the midshaft of both the right and left femora from each amputee and analyzed following standard forensic methods for histological estimation of age at death from the human femur. The histological age at death estimations for the thin sections from amputated bone were consistently lower than the actual chronological age of each individual, suggesting that the effects of amputation prohibit the effective use of age at death estimation methods. The nature of each amputation is unknown, which suggests that alternative factors could be responsible for the slowed bone turnover seen in the thin sections from the amputated bone. First, it is reasonable to assume that the amputations in this sample could have resulted from complications of diabetes mellitus rather than trauma so the possible effects on bone remodeling due to disease are explored. Second, the mobility of the decedents following their amputations is unknown so the histomorphological results could be due to disuse osteoporosis. PMID- 29179050 TI - First year nursing students use of social media within education: Results of a survey. AB - INTRODUCTION: Social media rapidly disseminates information but is a controversial learning platform in nurse education. This study aimed to explore how students viewed the use of Twitter, and other social media, in their first year of a nursing degree. AIM: The aim of this study was to evaluate first year student nurses' use of social media, before and after commencing a pre registration programme, where Twitter was used in a module. METHODOLOGY: A cross sectional approach using a descriptive survey was completed. METHODS: An online survey, that included Likert scale and open questions, was open for one month in 2016. SAMPLE: All students on Nursing Undergraduate Degrees, in Adult, Child and Mental Health, who were in the first year of their programme were eligible to participate. 121 students took part with a response rate of 32%. RESULTS: Most students were positive about using social media as they found it an engaging way to promote discussion and share information. Students use of Twitter changed in the first year with 19.8% using it once or more per week on commencement of the programme which increased to 45.5%; other social media platforms remained static. Most students (57.8%) understood the purpose of using Twitter although 14% reported that it was not used within their module; thus, not all students gained experience of using the social media. 81% of students said that using Twitter had been beneficial to increase awareness of nursing issues within their course. However, there were areas that students found difficult such as time, and not knowing what to say. CONCLUSION: The study suggests that teaching about social media, and incorporating it into learning activities, may be beneficial for students. However, more research into the subject using an experimental design to assess changes over time would be useful. PMID- 29179051 TI - Differences in pattern of variability for lower extremity kinematics between walking and running. AB - This study characterizes walking and running patterns in healthy individuals using linear and nonlinear methods Seventeen individuals (12 males, 5 females) volunteered for the study. 3D kinematic data during walking (WA) and running (RU) on a motorized treadmill were captured using reflective markers placed on lower body (200Hz). A single 25s trial (5000 data points) was collected for each gait task. WA speed was 1.39+/-0.12m/s, whereas RU speed was 2.56+/-0.27m/s. Variables of interest included ankle plantar/dorsi flexion, knee flexion/extension, knee abduction/adduction, hip flexion/extension, and hip abduction/adduction angles. For linear analysis, standard deviation (SD) and coefficient of variation (CV) were calculated for the entire time series for both conditions. Nonlinear analysis included assessing pattern of regularity of respective kinematic time series using approximate entropy (ApEn). Inferential analyses were conducted using MANOVA to compare selected dependent measures (p<0.05). SD for knee flexion/extension angle (WA=23.34+/-4.17, RU=27.51+/-5.25) and ankle plantar/dorsi flexion angle (WA=9.24+/-2.37, RU=12.88+/-2.00) were both greater during running. For all other variables, there were no significant differences in degree of variability between walking and running (p's>0.05). Running ApEn values were greater than walking ApEn values for knee flexion/extension (WA=0.14+/-0.02, RU=0.23+/-0.04), knee abduction/adduction (WA=0.18+/-0.07, RU=0.24+/-0.07), hip flexion/extension (WA=0.09+/-0.02, RU=0.17+/-0.04), and hip abduction/adduction (WA=0.12+/-0.03, RU=0.21+/-0.05). Greater variability was demonstrated during running across all joints compared to walking. This suggests that ApEn is more sensitive to detecting changes between different gait conditions than standard discrete measures of variability (SD). PMID- 29179052 TI - Using phone sensors and an artificial neural network to detect gait changes during drinking episodes in the natural environment. AB - BACKGROUND: Phone sensors could be useful in assessing changes in gait that occur with alcohol consumption. This study determined (1) feasibility of collecting gait-related data during drinking occasions in the natural environment, and (2) how gait-related features measured by phone sensors relate to estimated blood alcohol concentration (eBAC). METHODS: Ten young adult heavy drinkers were prompted to complete a 5-step gait task every hour from 8pm to 12am over four consecutive weekends. We collected 3-axis accelerometer, gyroscope, and magnetometer data from phone sensors, and computed 24 gait-related features using a sliding window technique. eBAC levels were calculated at each time point based on Ecological Momentary Assessment (EMA) of alcohol use. We used an artificial neural network model to analyze associations between sensor features and eBACs in training (70% of the data) and validation and test (30% of the data) datasets. RESULTS: We analyzed 128 data points where both eBAC and gait-related sensor data were captured, either when not drinking (n=60), while eBAC was ascending (n=55) or eBAC was descending (n=13). 21 data points were captured at times when the eBAC was greater than the legal limit (0.08mg/dl). Using a Bayesian regularized neural network, gait-related phone sensor features showed a high correlation with eBAC (Pearson's r>0.9), and >95% of estimated eBAC would fall between -0.012 and +0.012 of actual eBAC. CONCLUSIONS: It is feasible to collect gait-related data from smartphone sensors during drinking occasions in the natural environment. Sensor-based features can be used to infer gait changes associated with elevated blood alcohol content.

AB - This study examined a new approach for starting up a bioelectrochemical system (BES) for oxalate removal from an alkaline (pH > 12) and saline (NaCl 25 g/L) liquor. An oxalotrophic biofilm pre-grown aerobically onto granular graphite carriers was used directly as both the microbial inoculum and the BES anode. At anode potential of +200 mV (Ag/AgCl) the biofilm readily switched from using oxygen to graphite as sole electron acceptor for oxalate oxidation. BES performance was characterised at various hydraulic retention times (HRTs, 3-24 h), anode potentials (-600 to +200 mV vs. Ag/AgCl) and influent oxalate (25 mM) to acetate (0-30 mM) ratios. Maximum current density recorded was 363 A/m3 at 3 h HRT with a high coulombic efficiency (CE) of 70%. The biofilm could concurrently degrade acetate and oxalate (CE 80%) without apparent preference towards acetate. Pyro-sequencing analysis revealed that known oxalate degraders Oxalobacteraceae became abundant signifying their role in this novel bioprocess.

AB - This study investigated the performance of co-digesting cucumber residues, corn stover, and pig manure at different ratios. Microbial community structure was analyzed to elucidate functional microorganism contributing to methane production during co-digestion. Results show that mixing cucumber residues with pig manure and corn stover could significantly improved methane yields 1.27-3.46 times higher than mono-feedstock. The methane yields decreased with the cucumber residues increasing when the pig manure ratio was fixed at 4 and 3, and was opposite at ratio 5. The optimal mixture ratio was T2 with the highest methane yield (305.4 mL/g VS) and co-digestion performance index (1.97). The main microbiological community in T2 was bacteria of Firmicutes (44.6%), Bacteroidetes (32.5%), Synergistetes (3.8%) and archaea of Methanosaeta (37.1%), Methanospirillum (18.2%). The mixture ratios changed the microbial community structures. The adding proportion of cucumber residues changed the community composition of the archaea, especially the proportion of Methanosaeta. PMID- 29179055 TI - Postmortem biochemical investigation results in situations of fatal mechanical compression of the neck region. AB - Biochemical investigations performed in cases of mechanical asphyxia have provided diverging information over time. The purpose of the study presented herein was threefold: to investigate the postmortem stability of a series of molecules (thyroglobulin, iodothyronines, calcitonin, and parathyroid hormone) in blood after death, to determine the same molecules in a series of cases of suicidal hangings for which antemortem serum samples were available, and to measure the same molecules in postmortem serum obtained from different sampling sites thereby evaluating the distribution of these molecules in the specific samples. Preliminary results indicated postmortem stability of thyroglobulin, calcitonin, and parathyroid hormone levels, decreasing total and free T4 levels, and increasing total and free T3 concentrations. Our findings also showed that antemortem mechanical force applied to the neck region (hanging cases) may be accompanied by increased thyroglobulin in peripheral (femoral) blood, though a certain number of cases with nonincreased thyroglobulin levels may be observed. Lastly, our results revealed that hanging, manual, and ligature strangulation cases may be accompanied by increased thyroglobulin, total T3, and free T3 values in postmortem serum specimens obtained from blood sampled at different sampling sites, even in the absence of microscopically identified thyroid gland tissue damage. Such increases are more constant and important in arterial and venous blood samples obtained from sampling sites located in close vicinity of the thyroid gland.

AB - Very preterm birth influences brain development and may result in alterations of cortical morphometry. These structural alterations may interact with cognitive development. The aim of the present study was to investigate the structure function relationship in school-aged very preterm and term-born control children. A comprehensive neuropsychological test battery was administered to 41 very preterm (<32 weeks of gestation) and 30 term-born control children aged seven to twelve years. The automated method FreeSurfer was used to obtain cortical thickness and cortical surface area measures from T1-weighted MRI images. Regional cortical thickness differed between groups but differences disappeared when controlling for age. Global cortical thickness differed between groups in the right hemisphere (very preterm children>controls). No group differences occurred for cortical surface area. The relationship between cortical morphometry and cognition differed between very preterm and control children. In very preterm children, some cognitive domains correlated positively and others negatively with regional cortical thickness and cortical surface area. Our findings contribute to the understanding of the structure-function relationship in very preterm children and their term-born peers. They add to the notion that this relationship varies depending on the brain region and the cognitive function in question and suggest developmental differences between very preterm and term-born children.

It has been proposed as a putative biomarker of certain hormone- related adult life traits and diseases. Several evidence suggest that 2D:4D ratio may correlate with cardiovascular disease risk (e.g., coronary artery disease). AIMS: To investigate whether there is a possible relationship between digit ratio (especially 2D:4D ratio) and coronary artery disease (CAD), and age at CAD in north Chinese women. METHODS: Photographs of the two hands of 303 females (controls: 194; patients: 109) were collected. Left hand, right hand and right minus left hand (Dr-l) digit ratio were analyzed and compared. RESULTS: The mean values of digit ratio in patients with CAD were lower than controls for each hand. Significant differences of 2D:4D (left and right hand: P<0.01), 2D:5D (left hand: P<0.01; right hand: P<0.05) and 3D:4D (left hand: P<0.01) were found between two groups. There were no associations between 2D:4D ratio and age at CAD on both hands. CONCLUSION: Decreased digit ratio (especially 2D:4D ratio) may suggest a higher prenatal testosterone (lower prenatal oestrogen) exposure in north Chinese women with coronary artery disease.

However, no studies have been reported on the use of BPU to collect in vivo ovarian tissue in goats. The goals of this study were: (i) to test different biopsy needle sizes to collect ovarian tissue in situ using the BPU method (Experiment 1), and (ii) to study ovarian tissue features such as preantral follicle density, morphology, class distribution, and stromal cell density in ovarian fragments obtained in vivo through a laparoscopic BPU method (Experiment 2). In Experiment 1, goat ovaries (n = 20) were collected in a slaughterhouse and subjected to in situ BPU. Three needles (16, 18, and 20G) were tested. In Experiment 2, the most efficient biopsy needle from Experiment 1 was used to perform laparoscopic BPU in goats (n = 8). In Experiment 1, the recovery rate was greater (P < 0.05; range 50-62%) with 16G and 18G needles than the 20G (17%) needle. The mean weight of ovarian fragments collected by the 16G needle was greater (P < 0.05) than the 18G and the 20G needle. In Experiment 2, 62 biopsy attempts were performed and 52 ovarian fragments were collected (90% success rate). Overall, 2054 preantral follicles were recorded in 5882 histological sections analyzed. Mean preantral follicular density was 28.4 +/- 1.3 follicles per cm2. The follicular density differed (P < 0.05) among animals and ovarian fragments within the same animal. The mean stromal cell density in the ovarian fragments was 37.1 +/- 0.5 cells per 2500 MUm2, and differed (P < 0.05) among animals. Moreover, preantral follicle density and stromal cell density were associated (P < 0.001). The percentage of morphologically normal follicles was 70.1 +/- 1.2, and differed (P < 0.05) among animals. The majority (79%) of the morphologically normal follicles was classified as primordial follicles, and differed (P < 0.05) among animals and between ovaries. In summary, a laparoscopic BPU method has been developed to harvest ovarian tissue in vivo with a satisfactory success rate in goats. Furthermore, this study described for the first time that goat ovarian biopsy fragments have a high heterogeneity in follicular density, morphology, class distribution, and stromal cell density.

AB - Reversed-phase high-performance liquid chromatography (RP-HPLC) has been used to analyze Interferon alpha-2 (IFN-alpha2) as a pure protein or as a pharmaceutical preparation: a method for analyzing periplasmic IFN-alpha2 directly in osmotic shock extract has, however, never been reported. This work describes an RP-HPLC methodology for the qualitative and quantitative analysis of human IFN-alpha2a and IFN-alpha2b directly in bacterial periplasmic extracts or in purified preparations. The analytical method has been set up and validated for accuracy, precision, linearity, sensitivity and specificity. A recovery test indicated an average bias of ~1%, intra-day and inter-day quantitative determinations presented relative standard deviations always<=5%, while the working sensitivity was of ~0.3MUg of IFN-alpha2 (RSD=5%). The method proved to be suitable for detecting and quantifying also glycosylated and oxidized forms and N methionylated IFN-alpha2 molecules, it was, however, not able to distinguish between IFN-alpha2a and IFN-alpha2b. This rapid methodology allows the application of RP-HPLC as a powerful tool to monitor the production yield and quality of IFN-alpha2 in osmotic shock fluids, right after, or even during the fermentation process. PMID- 29179060 TI - Development, validation, and application of an UPLC-MS/MS method for norvancomycin analysis in human blood plasma. AB - Norvancomycin (NVCM) is used in treating patients with infections caused by drug resistant gram-positive bacteria. The NVCM plasma concentration varies greatly among individuals. To avoid the adverse drug reactions and prevent the presence of drug-resistant bacteria, the routine monitoring of NVCM in blood plasma was strongly recommended. However, there were few methods for plasma NVCM analysis. To the best of our knowledge, this is the first validated ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method for plasma NVCM analysis. The ion transition for NVCM was m/z 718.5>144.1. The flow rate was 0.4mL/min with a run time of 3.5min. The calibration range of the UPLC-MS/MS method was 1-100mg/L. The intra-day and inter-day inaccuracy and imprecision were -7.39%-10.27% and less than 11.55%. The internal standard (IS) normalized recovery and matrix factor were 68.24%-78.24% and 94.53% to 115.80%, respectively. The coefficient variations of IS normalized recovery and matrix factor were less than 11.24% and 9.14%. Age, body weight, and creatinine clearance affect NVCM plasma concentrations in 20 patients. Further studies are warranted to confirm the results. PMID- 29179061 TI - A UPLC-MS/MS method for simultaneous determination of 1-deoxynojirimycin and N methyl-1-deoxynojirimycin in rat plasma and its application in pharmacokinetic and absolute bioavailability studies. AB - A specific, sensitive, rapid, precise, and reliable UPLC-MS/MS-based method was designed for the first time for the simultaneous determination of 1 deoxynojirimycin (DNJ) and N-methyl-1-deoxynojirimycin (N-CH3-DNJ) in rat plasma. Miglitol was served as the internal standard (IS). An MN-NUCLEODUR HILIC column was assessed to separate the two compounds by isocratic elution using acetonitrile: water with 0.05% formic acid and 6.5mM ammonium acetate (72:28, v/v) at a flow rate of 0.4mL/min. A triple quadrupole mass spectrometer was operated in the positive ionization mode using multiple reaction monitoring (MRM), and it was employed to determine transitions of m/z 164.1->110.1, 178.1 >100.1, and 208.1->146.1 for DNJ, N-CH3-DNJ, and IS, respectively. The method of the two constituents was validated and the results were acceptable. The absolute bioavailability of DNJ and N-CH3-DNJ in rats was 50+/-9% and 62+/-24%, respectively. The method was then successfully used for the first time to study the pharmacokinetic behavior and absolute bioavailability of DNJ and N-CH3-DNJ in rats after intravenous (10mg/kg) and oral administration (80mg/kg). The results of this study might provide more information on preclinical pharmacokinetics and a solid basis for assessing the clinical efficacy of DNJ and N-CH3-DNJ. PMID- 29179062 TI - An effective method for preparation of high-purity pelargonidin-3-O-glucoside from strawberry and its protective effect on cellular oxidative stress. AB - Accumulating evidence indicates that consumption of berries may exert beneficial effects against oxidative stress mediated diseases. Pelargonidin-3-O-glucoside (Pg3G), a bioactive ingredient in strawberry, has been reported to possess a potent antioxidant capacity. This study was therefore designed to develop an effective method to prepare pure Pg3G from strawberry and investigate its protective effect against H2O2-induced oxidative stress. According to our results, Pg3G occupied 85.55% of total anthocyanin content in strawberry. 240mg of Pg3G with the purity of 97.26% was finally isolated from 320g of strawberry lyophilized powder (SLP) by combination of AB-8 macroporous resin and high-speed counter-current chromatography (HSCCC) technologies. Further study unveiled that Pg3G significantly inhibited H2O2-induced ROS generation, GSH depletion and mitochondrial dysfunction, thereby ameliorating H2O2-induced oxidative stress. Overall, this study suggests that pelargonidin-3-O-glucoside can be used as a natural bioactive agent to prevent cellular oxidative stress. PMID- 29179063 TI - Simultaneous determination of phenolic acids and diterpenoids and their comparative pharmacokinetic study in normal and acute blood stasis rats by UFLC MS/MS after oral administration of Guan-Xin-Shu-Tong capsules. AB - Guan-Xin-Shu-Tong capsules are one of the well-known and first-line Chinese traditional herbal formula for treating coronary heart disease. A validated and sensitive method via ultra fast liquid chromatography-tandem mass spectrometry (UFLC-MS/MS) was established to simultaneously determinate five phenolic acids and four diterpenoids in rats in order to investigate their pharmacokinetic profiles firstly. Analytes were extracted by ethyl acetate and determined via multiple reaction monitoring mode in both positive and negative ion modes. The values for limit of quantification were in range of 0.025-1.250ng/ml. Inter- and intra-day precisions were no more than 10.9% with accuracy of -11.0%-10.6%, meanwhile the stable and suitable extraction recoveries were also obtained. And finally such excellent method was used to compare the pharmacokinetics of nine compounds in normal and acute blood stasis rats after oral administration of Guan Xin-Shu-Tong capsules. PMID- 29179065 TI - Reaction profiling of a set of acrylamide-based human tissue transglutaminase inhibitors. AB - The major function of the enzyme human tissue transglutaminase (TG2) is the crosslinking of proteins via a transamidation between the gamma-carboxamide of a glutamine and the epsilon-amino group of a lysine. Overexpression of TG2 can lead to undesirable outcomes and has been linked to conditions such as fibrosis, celiac disease and neurodegenerative diseases. Accordingly, TG2 is a tempting drug target. The most effective TG2 inhibitors to date are small-molecule peptidomimetics featuring electrophilic warheads that irreversibly modify the active site catalytic cysteine (CYS277). In an effort to facilitate the design of such TG2 inhibitors, we undertook a quantum mechanical reaction profiling of the Michael reaction between a set of six acrylamide-based known TG2 inhibitors and the TG2 CYS277. The inhibitors were docked into the active site and the coordinates were refined by MD simulations prior to modelling the covalent modification of the CYS277 thiolate. The results of QM/MM MD umbrella sampling applied to reaction coordinates driving the Michael reaction are presented for two approximations of the Michael reaction: a concerted reaction (simultaneous thiolate attack onto the acrylamide warhead and pronation from the adjacent HIS335) and a two-stage reaction (consecutive thiolate attack and protonation). The two-stage approximation of the Michael reaction gave the better results for the evaluation of acrylamide-based potential TG2 inhibitors in silico. Good correlations were observed between the experimental TG2 IC50 data and the calculated activation energies over the range 0.0061-6.3MUM (three orders of magnitude) and we propose that this approach may be used to evaluate acrylamide based potential TG2 inhibitors. PMID- 29179064 TI - A simple and highly sensitive UPLC-ESI-MS/MS method for the simultaneous quantification of nicotine, cotinine, and the tobacco-specific carcinogens N' nitrosonornicotine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone in serum samples. AB - According to the World Health Organization, the consumption of tobacco products is the single largest cause of preventable deaths in the world, exceeding the total aggregated number of deaths caused by diseases such as AIDS, tuberculosis, and malaria. An important element in the evaluation of the health risks associated with the consumption of tobacco products is the assessment of the internal exposure to the tobacco constituents responsible for their addictive (e.g. nicotine) and carcinogenic (e.g. N-nitrosamines such as NNN and NNK) properties. However, the assessment of the serum levels of these compounds is often challenging from an analytical standpoint, in particular when limited sample volumes are available and low detection limits are required. Currently available analytical methods often rely on complex multi-step sample preparation procedures, which are prone to low analyte recoveries and ex-vivo contamination due to the ubiquitous nature of these compounds as background contaminants. In order to circumvent these problems, we report a facile and highly sensitive method for the simultaneous quantification of nicotine, cotinine, NNN, and NNK in serum samples. The method relies on a simple "one pot" liquid-liquid extraction procedure and isotope dilution ultra-high pressure (UPLC) hydrophilic interaction liquid chromatography (HILIC) coupled with tandem mass spectrometry. The method requires only 10MUL of serum and presents a limit of quantification of 0.02nmol (3000pg/mL) nicotine, 0.6pmol (100pg/mL) cotinine, 0.05pmol NNK (10pg/mL), and 0.06pmol NNN (10pg/mL), making it appropriate for pharmacokinetic evaluations. PMID- 29179066 TI - Rice yield in response to climate trends and drought index in the Mun River Basin, Thailand. AB - Rice yields in Thailand are among the lowest in Asia. In northeast Thailand where about 90% of rice cultivation is rain-fed, climate variability and change affect rice yields. Understanding climate characteristics and their impacts on the rice yield is important for establishing proper adaptation and mitigation measures to enhance productivity. In this paper, we investigate climatic conditions of the past 30years (1984-2013) and assess the impacts of the recent climate trends on rice yields in the Mun River Basin in northeast Thailand. We also analyze the relationship between rice yield and a drought indicator (Standardized Precipitation and Evapotranspiration Index, SPEI), and the impact of SPEI trends on the yield. Our results indicate that the total yield losses due to past climate trends are rather low, in the range of <50kg/ha per decade (3% of actual average yields). In general, increasing trends in minimum and maximum temperatures lead to modest yield losses. In contrast, precipitation and SPEI-1, i.e. SPEI based on one monthly data, show positive correlations with yields in all months, except in the wettest month (September). If increasing trends of temperatures during the growing season persist, a likely climate change scenario, there is high possibility that the yield losses will become more serious in future. In this paper, we show that the drought index SPEI-1 detects soil moisture deficiency and crop stress in rice better than precipitation or precipitation based indicators. Further, our results emphasize the importance of spatial and temporal resolutions in detecting climate trends and impacts on yields. PMID- 29179067 TI - How wildfire risk is related to urban planning and Fire Weather Index in SE France (1990-2013). AB - Wildfires burn >450,000ha of forest every year in Euro-Mediterranean countries. Many fires originate in the Wildland Urban Interface (WUI) where housing density and weather conditions affect fire occurrence. Housing density is determined by long term land use policies while weather conditions evolve quickly. The first objective was to quantify the impacts of land use policy on WUI characteristics and fire risk in SE France during 1990-2012. The second objective was to quantify how Fire Weather Index (FWI) is related to fire occurrence. WUI was mapped from 1990, 1999, and 2012 building layers and crossed with a NDVI derived vegetation layer. In all, 12 WUI categories were derived: 4 building density classes and 3 vegetation layers. The I87 FWI was based on daily temperature, wind speed, relative humidity and soil water content. Despite a 30% increase in the number of new buildings, WUI area increased by only 5% as new housing filled in open space in existing WUI area. This trend can be linked to national level urban planning legislation and forest fire protection laws. Major driver variables determining housing location were aspect, slope, and distance to city centers. Fire frequency and burned area were nonlinearly related to FWI: 73% of the 99 fires occurred during weeks with FWI values >=90 even though these accounted for only 44% of all weeks. Burned area was even more sensitive to FWI since 97% of total burned area occurred during weeks with mean FWI values >=90. All days with burned areas >100ha had FWI values >150. The study demonstrated that WUI legislation can be an efficient tool to limit WUI fire risk. FWI results suggest the predicted increase in extreme summer heat events with global warming could increase burned area as firefighting resources are stretched beyond capacity. PMID- 29179069 TI - Renewable energy powered membrane technology: Impact of pH and ionic strength on fluoride and natural organic matter removal. AB - Real water pH and ionic strength vary greatly, which influences the performance of membrane processes such as nanofiltration (NF) and reverse osmosis (RO). Systematic variation of pH (3-12) and ionic strength (2-10g/L as total dissolved solids (TDS)) was undertaken with a real Tanzanian water to investigate how water quality affects retention mechanisms of fluoride (F) and natural organic matter (NOM). An autonomous solar powered NF/RO system driven by a solar array simulator was supplied with constant power from a generator. An open NF (NF270) and a brackish water RO (BW30) membrane were used. A surface water with a very high F (59.7mg/L) and NOM (110mgC/L) was used. Retention of F by NF270 was <20% at pH <6, increased to 40% at pH6, and 60-70% at pH7-12, indicating a dominance of charge repulsion while being ineffective in meeting the guideline of 1.5mg/L. Increase in ionic strength led to a significant decline in retention of F (from 70 to 50%) and electrical conductivity (from 60 to 10%) by NF270, presumably due to charge screening. In contrast, BW30 retained about 50% of F at pH3, >80% at pH4, and about 99% at pH >5, due to the smaller pore size and hence a more dominant size exclusion. In consequence, only little impact of ionic strength increase was observed for BW30. The concentration of NOM in permeates of both NF270 and BW30 were typically <2mg/L. This was not affected by pH or ionic strength due to the fact that the bulk of NOM was rejected by both membranes through size exclusion. The research is carried out in the context of providing safe drinking water for rural and remote communities where infrastructure is lacking, and water quality varies significantly. While other studies focus on energy fluctuations, this research emphasises on feed water quality that affects system performance and may alter due to a number of environmental factors. PMID- 29179068 TI - Persistent organic pollutants (POPs) in blood and blubber of common bottlenose dolphins (Tursiops truncatus) at three northern Gulf of Mexico sites following the Deepwater Horizon oil spill. AB - Common bottlenose dolphins (Tursiops truncatus), including those impacted by the 2010 Deepwater Horizon (DWH) oil spill, inhabit the coastal and estuarine waters of the northern Gulf of Mexico (GoM). In response to the spill, dolphin health assessments conducted in Barataria Bay, Louisiana - a site that experienced heavy and prolonged oiling - uncovered a high prevalence of health abnormalities and individuals in poor body condition. Although the health effects observed were suggestive of petroleum toxicity, a lack of pre-spill information regarding dolphin health raises the possibility that other environmental factors may have contributed to the adverse health of dolphins in this oil-impacted area. To assess how exposure to other environmental pollutants may affect the health of northern GoM dolphin populations impacted by the DWH oil spill, a suite of 69 persistent organic pollutants (POPs), including PCBs, PBDEs and organochlorine pesticides, was determined in blood and a subset of blubber samples collected during health assessments of 145 bottlenose dolphins at three GoM sites: two oil impacted sites - Barataria Bay, LA (BB), and Mississippi Sound, MS (MS) and an unimpacted reference site - Sarasota Bay, FL (SB). Overall, levels of POPs at all three sites appeared comparable or lower than concentrations previously reported for coastal bottlenose dolphin populations outside of the northern GoM. POP levels measured in BB dolphins were also comparable or lower than those measured at the unimpacted reference site (SB) within the northern GoM. Additionally, the relationship between blubber and blood contaminant levels in a smaller subset of BB and SB suggests that BB animals were not experiencing elevated blood contaminant concentrations as a result of their poor body condition. Cumulatively, these results suggest that background levels of POPs measured are unlikely to produce the health abnormalities previously reported for BB dolphins. PMID- 29179070 TI - Biochar modulates heavy metal toxicity and improves microbial carbon use efficiency in soil. AB - Soil organic carbon is essential to improve soil fertility and ecosystem functioning. Soil microorganisms contribute significantly to the carbon transformation and immobilisation processes. However, microorganisms are sensitive to environmental stresses such as heavy metals. Applying amendments, such as biochar, to contaminated soils can alleviate the metal toxicity and add carbon inputs. In this study, Cd and Pb spiked soils treated with macadamia nutshell biochar (5% w/w) were monitored during a 49days incubation period. Microbial phospholipid fatty acids (PLFAs) were extracted and analysed as biomarkers in order to identify the microbial community composition. Soil properties, metal bioavailability, microbial respiration, and microbial biomass carbon were measured after the incubation period. Microbial carbon use efficiency (CUE) was calculated from the ratio of carbon incorporated into microbial biomass to the carbon mineralised. Total PLFA concentration decreased to a greater extent in metal contaminated soils than uncontaminated soils. Microbial CUE also decreased due to metal toxicity. However, biochar addition alleviated the metal toxicity, and increased total PLFA concentration. Both microbial respiration and biomass carbon increased due to biochar application, and CUE was significantly (p<0.01) higher in biochar treated soils than untreated soils. Heavy metals reduced the microbial carbon sequestration in contaminated soils by negatively influencing the CUE. The improvement of CUE through biochar addition in the contaminated soils could be attributed to the decrease in metal bioavailability, thereby mitigating the biotoxicity to soil microorganisms. PMID- 29179071 TI - Biochar decreased the bioavailability of Zn to rice and wheat grains: Insights from microscopic to macroscopic scales. AB - Zn deficiency is a critical problem for many crops and human populations worldwide. Soil biochar amendment has recently been promoted as a sustainable agricultural practice. However, its effect on the bioavailability of micronutrients (especially Zn) to crops has not been fully addressed. This study investigated the impact of long-term biochar application in soils on Zn bioavailability to rice and wheat, using field experiments, and batch sorption/desorption experiments, in combination with extended X-ray absorption fine structure spectroscopy (EXAFS). In field soils biochar amendment increased total Zn content, but significantly decreased CaCl2-extractable Zn concentrations. Intriguingly, the uptake of Zn to wheat and rice grains was decreased. At high biochar application rates of 124 and 270t/ha the Zn concentrations in wheat grains (36.6 and 37.5mg/kg) reached a deficient level, lower than the recommended concentration of 45mg/kg. The batch experiments showed that biochar application at a cumulative rate of 10.5, 15.8, 31.5, 124, and 270t/ha significantly increased soil pH and soil organic matter (SOM) content, resulting in greater sorption and lower desorption of Zn. The EXAFS results demonstrated that the main forms of sorbed Zn were outer-sphere Zn complexes, Zn illite, Zn-kaolinite and Zn-OM. The proportion of Zn-OM increased with increasing biochar application rates, suggesting that higher SOM might be more effective in immobilizing Zn and thus decreasing the Zn bioavailability. These results on the microscopic and macroscopic scales improved our understanding of the Zn bioavailability to crops, and raised potential concerns on the Zn deficiency in agricultural soils with long-term biochar application. PMID- 29179072 TI - Anaerobic digestion coupled with digestate injection reduced odour emissions from soil during manure distribution. AB - This work aimed to measure the odour impact of untreated cow and pig slurries and treated (digestate and liquid fraction of digestate) manures when they were used on soil at a field scale, while also testing different spreading methods, i.e. surface vs. injection. Five experiments were performed in 2012-2016 on different farms. Odours were quantitatively (specific odour emission rate - SOER) (OUEm-2h 1) measured by using dynamic olfactometry and qualitatively, i.e. to obtain an "odour fingerprint", by using an electronic nose (EN). Anaerobic digestion was effective in allowing the reduction of potential odour emission from digestates, so that when they were dosed on soil, odours emitted were much lower than those from soils on which untreated slurries were used. Slurries/digestate injection reduced much more odour emitted by soils so that SOER tended to become more similar to that of the control (untreated soil) although the odours were slightly greater. Odour fingerprint data indicated that there was a direct correlation between SOER and odour fingerprints. This was due to the ability of EN to detect ammonia, S-compounds and methane that were (the first two mainly), also, responsible for odours. Very good regression was found for Log SOER and EN by using a Partial Least Square (PLS) approach (R2=0.73; R2cv=0.66; P<0.01) for matrices used to fertilize soils in lab tests. Unfortunately, regression was not so good when odour data from field experiments on soil were used, so that EN cannot be proposed to replace olfactometry. EN fingerprints for control (Blank) and injected organic matrices were virtually identical, due to the creation of cavities in the soil during the injection that decreased the treated surface. Anaerobic digestion and subsequent digestate injection allowed us to reduce odour impact, avoiding annoyance to local inhabitants. PMID- 29179073 TI - Identifying change in spatial accumulation of soil salinity in an inland river watershed, China. AB - Soil salinity accumulation is strong in arid areas and it has become a serious environmental problem. Knowledge of the process and spatial changes of accumulated salinity in soil can provide an insight into the spatial patterns of soil salinity accumulation. This is especially useful for estimating the spatial transport of soil salinity at the watershed scale. This study aimed to identify spatial patterns of salt accumulation in the top 20cm soils in a typical inland watershed, the Sangong River watershed in arid northwest China, using geostatistics, spatial analysis technology and the Lorenz curve. The results showed that: (1) soil salt content had great spatial variability (coefficient variation >1.0) in both in 1982 and 2015, and about 56% of the studied area experienced transition the degree of soil salt content from one class to another during 1982-2015. (2) Lorenz curves describing the proportions of soil salinity accumulation (SSA) identified that the boundary between soil salinity migration and accumulation regions was 24.3m lower in 2015 than in 1982, suggesting a spatio-temporal inequality in loading of the soil salinity transport region, indicating significant migration of soil salinity from the upstream to the downstream watershed. (3) Regardless of migration or accumulation region, the mean value of SSA per unit area was 0.17kg/m2 higher in 2015 than 1982 (p<0.01) and the increasing SSA per unit area in irrigated land significantly increased by 0.19kg/m2 compared with the migration region. Dramatic accumulation of soil salinity in all land use types was clearly increased by 0.29kg/m2 in this agricultural watershed during the studied period in the arid northwest of China. This study demonstrates the spatial patterns of soil salinity accumulation, which is particularly useful for estimating the spatial transport of soil salinity at the watershed scale. PMID- 29179074 TI - Atmospheric CO2 capture for the artificial photosynthetic system. AB - The aim of these studies is to evaluate the ambient CO2 capture abilities of the membrane contactor system in the same conditions as leafs, such as ambient temperature, pressure and low CO2 concentration, where the only driving force is the concentration gradient. The polysulfone membrane employed was made by a phase inversion process and characterized by ESEM micrographs which were used to determine the thickness, asymmetry and pore size. Besides, the porosity of the membrane was measured from the membrane and polysulfone density correlation and the hydrophobicity was analyzed by contact angle measurements. Moreover, the compatibility of membrane and absorbent was evaluated, in order to exclude wetting issues by meaning of swelling, dynamic contact angle and AFM analysis. The prepared membranes were introduced into a cross flow module and used as contactors between CO2 and the absorbing media, a potassium hydroxide solution. The influence of the membrane thickness, absorbent stirring rate, solution pH and absorption time on CO2 capture were evaluated. Absorbent solution stirring rate showed no statistically significant influence on absorption. We observed a non linear correlation between the capture rate and the increase of absorbent solution pH as well as absorption time. The results showed that the efficiency of our CO2 capture system is similar to stomatal carbon dioxide assimilation rate, achieving stable value of 20MUmol/m2.s after 1h of experiment. PMID- 29179075 TI - Manure management and public health: Sanitary and socio-economic aspects among urban livestock-keepers in Cambodia. AB - Livestock manure is a valuable source of nutrients for crop production, but can also pose a public health hazard and have negative environmental impacts. This study investigated manure management practices among urban and peri-urban livestock keepers in Cambodia, to identify risk behaviours and socio-economic aspects associated with the handling of manure. A survey including 204 households was conducted, using a structured questionnaire with questions on demographics, socio-economic characteristics and household practices related to manure management. Faecal samples were obtained from pig pens and pig manure storage units for analysis of the potential zoonotic pathogens Salmonella enterica (Polymerase Chain Reaction (PCR)), Ascaris suum and Trichuris suis (McMaster flotation technique). The survey revealed a difference in management between cattle and pig manure. Cattle manure was most commonly used as fertiliser for crop production (66%) (p<0.001), whereas pig manure was most commonly dumped in the environment (46%) (p<0.001). Logistic regression models showed that households with a lower socio-economic position were more likely to dump pig manure (p<0.001), with scarcity of agricultural land (p<0.001) and lack of carts for transportation of manure (p<0.01) being identified as contributing factors. Salmonella enterica was detected in 9.7% of manure samples, while Ascaris suum and Trichuris suis were detected in 1.6% and 2.4% of the samples, respectively. The results presented in this study indicate that manure management by urban and peri-urban households may pose a public health threat and an environmental hazard. There is evidently a need for further knowledge support to the livestock keepers to promote good management practices. PMID- 29179076 TI - Urinary concentrations of parabens and reproductive parameters in young men. AB - Parabens are a group of alkyl esters of p-hydroxybenzoic acid that are commonly added to personal care products, cosmetics, pharmaceuticals and beverage and food processing as antimicrobial preservatives. Parabens have been reported to show estrogenic effects and affect male reproduction function in animal models, but human epidemiologic studies are still scarce. The objective of this study was to examine associations between urinary concentrations of parabens and semen quality and reproductive hormone levels. This was a cross-sectional study with 215 young university students (18-23years old) recruited between 2010 and 2011 in Southern Spain (Murcia Region). All men provided a urine, blood and semen sample on a single day. Urinary paraben concentrations (methylparaben, ethylparaben, propylparaben and butylparaben) were measured by dispersive liquid-liquid microextraction and ultra-high performance liquid chromatography with tandem mass spectrometry detection. Semen quality was evaluated by measuring volume, sperm concentration, total sperm count (TSC), motility and morphology following WHO guidelines. Serum samples were analyzed for reproductive hormones, including follicle-stimulating hormone, luteinizing hormone, testosterone, inhibin B and estradiol using immunoassays. Associations between urinary concentrations of parabens and semen quality parameters and reproductive hormone levels were examined using linear regression, adjusting for potential covariates. Ninety-four percent of the men had detectable urinary concentrations of parabens. After taking into account important covariates, urinary concentrations of parabens or their molar sum were not significantly associated with any semen parameters or any of the reproductive hormone levels. Relative to men in the lowest quartile of sum of urinary paraben concentrations, the adjusted difference (95% CI) of TSC (millions) for men in the 2nd, 3rd, and 4th quartiles were 4.1% (-37.1;45.3), 1.6% (-41.9;38.8), and -9.8% (-52.5;32.8), respectively (P-trend=0.55). Our results suggest that, in young men, urinary parabens may not adversely impact reproductive function, but further research is warranted to confirm these findings in other male populations.

AB - Nano-enabled consumer products are a likely source of nanoparticles in the environment and a number of studies have shown the release of nanoparticles from commercial products. Predicted environmental concentrations have been calculated but there is a need for real measurement data to validate these calculations. However, the detection of engineered nanoparticles in environmental matrices is challenging because of the low predicted environmental concentrations which may be in the ng/L range. In this study nanosized Ag, CeO2 and TiO2 have been measured in multiple surface water samples collected along the rivers Meuse and IJssel in the Netherlands using single-particle ICP-MS as measurement technique. Validation of the analytical method showed its capability to quantitatively determine nanoparticles at low concentrations. Concentration mass detection limits for Ag, CeO2 and TiO2 were 0.1ng/L, 0.05ng/L and 10ng/L respectively. Size detection limits for Ag, CeO2 and TiO2 were 14, 10 and 100nm. The results of the study confirm the presence of nano-sized Ag and CeO2 particles and micro-sized TiO2 particles in these surface waters. n-Ag was present in all samples in concentrations ranging from 0.3 to 2.5ng/L with an average concentration of 0.8ng/L and an average particle size of 15nm. n-CeO2 was found in all samples with concentrations ranging from 0.4 to 5.2ng/L with an average concentration of 2.7ng/L and an average particle size of 19nm. Finally, MU-TiO2 was found in all samples with a concentration ranging from 0.2 to 8.1MUg/L with an average concentration of 3.1MUg/L and an average particle size of 300nm. The particle sizes that were found are comparable with the particle sizes that are used in nanomaterial applications and consumer products. The nanoparticle concentrations confirm the predicted environmental concentrations values in water for all three nanoparticles.

AB - Large river-floodplain systems which provide a variety of societal, economic and biological benefits are undergoing extensive and intensive human disturbance. However, floodplain lakes responses to multiple stressors are poorly understood. The Yangtze River and its floodplain which provide water and food resources for more than 300 million people are an important region in China. Hydrological regulation as well as socio-economic development have brought profound negative influence on this ecologically important area. To improve understanding of decadal-scale responses of floodplain lakes to multiple stressors, lake sediment proxies including particle size, geochemical elements, diatoms and chironomids were analysed in a lead-210 dated core from Futou Lake. The analyses show that dams constructed in 1935 and the early 1970s stabilized hydrological conditions in Futou Lake and impeded the interaction with the Yangtze River, resulting in a decrease in major elements (e.g., Mg, Al, Fe) transported into the lake and an increase of macrophyte-related chironomids (C. sylvestris-type, P. penicillatus type and Paratanytarsus sp.). After the late 1990s, further decreases in major elements and increases in median grain size are attributed to the erosion of the Yangtze riverbed and declining supply of major elements-enriched sediments from the upper Yangtze caused by the impoundment of the Three Gorges Dam. Chironomid and diatom assemblages indicate that hydrological stabilization caused by dam constructions stimulated the growth of macrophytes, which may be important in buffering against an ecosystem state change towards a phytoplankton-dominated and turbid state with ongoing eutrophication. However, a recent increase in Zn, TP and the emergence of eutrophic diatom and chironomid species indicate initial signs of water quality deterioration which may be related to the combined effects of hydrological stabilization and aquaculture. Over all, the sediment record from Futou Lake emphasizes the importance of interactions between hydrological change and pollutant loads in determining floodplain lake ecosystem state. PMID- 29179079 TI - Effects of sea level rise, land subsidence, bathymetric change and typhoon tracks on storm flooding in the coastal areas of Shanghai. AB - We compared the effects of three key environmental factors of coastal flooding: sea level rise (SLR), land subsidence (LS) and bathymetric change (BC) in the coastal areas of Shanghai. We use the hydrological simulation model MIKE 21 to simulate flood magnitudes under multiple scenarios created from combinations of the key environmental factors projected to year 2030 and 2050. Historical typhoons (TC9711, TC8114, TC0012, TC0205 and TC1109), which caused extremely high surges and considerable losses, were selected as reference tracks to generate potential typhoon events that would make landfalls in Shanghai (SHLD), in the north of Zhejiang (ZNLD) and moving northwards in the offshore area of Shanghai (MNS) under those scenarios. The model results provided assessment of impact of single and compound effects of the three factors (SLR, LS and BC) on coastal flooding in Shanghai for the next few decades. Model simulation showed that by the year 2030, the magnitude of storm flooding will increase due to the environmental changes defined by SLR, LS, and BC. Particularly, the compound scenario of the three factors will generate coastal floods that are 3.1, 2.7, and 1.9 times greater than the single factor change scenarios by, respectively, SLR, LS, and BC. Even more drastically, in 2050, the compound impact of the three factors would be 8.5, 7.5, and 23.4 times of the single factors. It indicates that the impact of environmental changes is not simple addition of the effects from individual factors, but rather multiple times greater of that when the projection time is longer. We also found for short-term scenarios, the bathymetry change is the most important factor for the changes in coastal flooding; and for long-term scenarios, sea level rise and land subsidence are the major factors that coastal flood prevention and management should address. PMID- 29179080 TI - Toxicity assessment within the application of in situ contaminated sediment remediation technologies: A review. AB - Polluted sediment represents a great problem for aquantic environments with potential direct acute and chronic effects for the biota and can be tackled with both in situ and ex situ treatments. Once dredging activities are not compulsory, sediment can be kept in place and managed with techniques involving the use of amendment and/or capping. Before their application, the assessment of their potential impact to the target environment cannot ignore the safe-by-design approach. The role of toxicity in in situ sediment remediation was reviewed discussing about how it can be used for the selection of amendments and the monitoring of treatment technologies. Results evidenced that capping technology coupled to activated carbon (AC) is the most frequently applied approach with effects varying according to the rate of contamination in treated sediment, the amount of AC used (% v/v), and target biological models considered. Little data are available for zerovalent iron as well as other minor amending agents such as hematite, natural zeolite, biopolymers and organoclays. Current (eco )toxicological information for in situ sediment remediation technologies is fragmentary and incomplete or entirely missing, making also the interpretation of existing data quite challenging. In situ sediment remediation represents an interesting potentially effective approach for polluted sediment recovering. As its application in some lab-based and field studies reported to induce negative effects for target organisms, amendments and capping agents must be attentively evaluated for short- and long-term environmental effects, also in the perspective of the remediated site monitoring and maintenance. PMID- 29179081 TI - Potential urban runoff impacts and contaminant distributions in shoreline and reservoir environments of Lake Havasu, southwestern United States. AB - Heavy metal, nutrient, and hydrocarbon levels in and adjacent to Lake Havasu, a regionally significant water supply reservoir with a highly controlled, dynamic flow regime, are assessed in relation to possible stormwater runoff impacts from an arid urban center. Shallow groundwater and sediment analyses from ephemeral drainage (wash) mouths that convey stormwater runoff from Lake Havasu City, Arizona to the reservoir, provided contaminant control points and correlation ties with the reservoir environment. Fine-grain sediments tend to contain higher heavy metal concentrations whereas nutrients are more evenly distributed, except low total organic carbon levels from young wash mouth surfaces devoid of vegetation. Heavy metal and total phosphate sediment concentrations in transects from wash mouths into the reservoir have mixed and decreasing trends, respectively. Both series may indicate chemical depositional influences from urban runoff, yet no statistically significant concentration differences occur between specific wash mouths and corresponding offshore transects. Heavy metal pollution indices of all sediments indicate no discernible to minor contamination, indicating that runoff impacts are minimal. Nevertheless, several heavy metal concentrations from mid-reservoir sediment sites increase southward through the length of the reservoir. Continual significant water flow through the reservoir may help to disperse locally derived runoff particulates, which could mix and settle down gradient with chemical loads from upriver sources and local atmospheric deposition. Incorporating the shoreline environment with the reservoir investigation provides spatial continuity in assessing contaminant sources and distribution patterns. This is particularly acute in the investigation of energetic, flow-through reservoirs in which sources may be overlooked if solely analyzing the reservoir environment. PMID- 29179082 TI - Effect of short-term aluminum stress and mycorrhizal inoculation on nitric oxide metabolism in Medicago truncatula roots. AB - Aluminum (Al) toxicity can induce oxidative and nitrosative stress, which limits growth and yield of crop plants. Nevertheless, plant tolerance to stress may be improved by symbiotic associations including arbuscular mycorrhiza (AM). Nitric oxide (NO) is a signaling molecule involved in physiological processes and plant responses to abiotic and biotic stresses. However, almost no information about the NO metabolism has been gathered about AM. In the present work, Medicago truncatula seedlings were inoculated with Rhizophagus irregularis, and 7-week-old plants were treated with 50MUM AlCl3 for 3h. Cytochemical and molecular techniques were used to measure the components of the NO metabolism, including NO content and localization, expression of genes encoding NO-synthesis (MtNR1, MtNR2 and MtNIR1) and NO-scavenging (MtGSNOR1, MtGSNOR2, MtHB1 and MtHB2) enzymes and the profile of protein tyrosine nitration (NO2-Tyr) in Medicago roots. For the first time, NO and NO2-Tyr accumulation was connected with fungal structures (arbuscules, vesicles and intercellular hyphae). Expression analysis of genes encoding NO-synthesis enzymes indicated that AM symbiosis results in lower production of NO in Al-treated roots in comparison to non-mycorrhizal roots. Elevated levels of transcription of genes encoding NO-scavenging enzymes indicated more active NO scavenging in AMF-inoculated Al-treated roots compared to non-inoculated roots. These results were confirmed by less NO accumulation and lower protein nitration in Al-stressed mycorrhizal roots in comparison to non mycorrhizal roots. This study provides a new insight in NO metabolism in response to arbuscular mycorrhiza under normal and metal stress conditions. Our results suggest that mycorrhizal fungi decrease NO and tyrosine nitrated proteins content in Al-treated Medicago roots, probably via active NO scavenging system. PMID- 29179083 TI - Atmospheric CO2 enrichment effect on the Cu-tolerance of the C4 cordgrass Spartina densiflora. AB - A glasshouse experiment was designed to investigate the effect of the co occurrence of 400 and 700ppm CO2 at 0, 15 and 45mM Cu on the Cu-tolerance of C4 cordgrass species Spartina densiflora, by measuring growth, gas exchange, efficiency of PSII, pigments profiles, antioxidative enzyme activities and nutritional balance. Our results revealed that the rising atmospheric CO2 mitigated growth reduction imposed by Cu in plants grown at 45mM Cu, leading to leaf Cu concentration bellow than 270mgKg-1 Cu, caused by an evident dilution effect. On the other hand, non-CO2 enrichment plants showed leaf Cu concentration values up to 737.5mgKg-1 Cu. Furthermore, improved growth was associated with higher net photosynthetic rate (AN). The beneficial effect of rising CO2 on photosynthetic apparatus seems to be associated with a reduction of stomatal limitation imposed by Cu excess, which allowed these plants to maintain greater iWUE values. Also, plants grown at 45mM Cu and 700ppm CO2, showed higher ETR values and lower energy dissipation, which could be linked with an induction of Rubisco carboxylation and supported by the recorded amelioration of N imbalance. Furthermore, higher ETR values under CO2 enrichment could lead to an additional consumption of reducing equivalents. Idea that was reflected in the lower values of ETRmax/AN ratio, malondialdehyde (MDA) and ascorbate peroxidase (APx), guaiacol peroxidase (GPx) and superoxide dismutase (SOD) activities under Cu excess, which could indicate a lower production of ROS species under elevated CO2 concentration, due to a better use of absorbed energy. PMID- 29179084 TI - Depression, anxiety and PTSD in sexually abused adolescents: Association with self-efficacy, coping and family support. AB - Sexual abuse has the potential to generate serious emotional consequences for its victims, but there is high variability in the symptoms reported by different victims. Therefore, it is necessary to ascertain the factors associated with the symptoms presented by sexual abuse victims. The aim of the study was to use a single model to evaluate the relationship between sexual abuse characteristics (frequency, violence, relation with the aggressor and physical commitment), cognitive and behavioral factors (self-efficacy, active coping and perceived family support) and internalizing symptoms (anxiety, depression and posttraumatic stress) in a group of sexually abused adolescents. The participants included 106 female adolescent victims of sexual abuse (M=14.25years, SD=1.74). The results of a path analysis indicated that sexual abuse characteristics were unrelated to symptomatology. Only a negative relationship was observed between the victim's relationship with the aggressor and PTSD symptomatology. The violence of the sexual abuse was negatively related to self-efficacy, and self-efficacy was positively related to active coping and negatively related to symptomatology. Finally, the perception of family support was positively related to self-efficacy and negatively related to symptomatology. These results suggest the need to consider the studied factors in the process of psychotherapy with victims of sexual abuse. PMID- 29179085 TI - Anisotropy (optical, electrical and thermal conductivity) in thin polarizing films for UV/Vis regions of spectrum: Experimental and theoretical investigations. AB - In the present work, the quantum theoretical calculations of the molecular structures of the three newly synthesized azomethine dyes: have been predicted using Density Functional Theory (DFT) in solvent dimethylformamide (DMF). The geometries of the azomethine dyes were optimized using the PBE1PBE/6-31+G level of the theory. In addition, the electronic spectra of these compounds in solvent DMF were carried out using the TDPBE1PBE, TDPBEPBE, TDB3LYP methods with 6-31G, 6 31+G, 6-31+G*, 6-31++G* basis sets. After quantum-chemical calculations three new azomethine dyes for optoelectronic applications were synthesized. Based on polyvinyl alcohol (PVA) and the new synthesized azomethine dyes polarizing films for UV/Vis regions of the spectrum were developed. The main optical parameters of polarizing PVA-films (Transmittance and Polarization Efficiency) have been measured and discussed. Anisotropy of electrical and thermal conductivity of the PVA-films has been investigated. PMID- 29179086 TI - Xylenes transformation over zeolites ZSM-5 ruled by acidic properties.

Most sponge species in the Class Demospongiae have a skeleton of siliceous spicules and/or protein spongin or both. The first aim of this study was to perform the morphological and structural characterization of the siliceous spicules of four species belonging to Class Demospongiae (Suberites domuncula, Axinella polypoides, Axinella damicornis and Agelas oroides) collected around Gokceada Island-Turkey (Northern Aegean Sea). The characterizations were carried out using a combination of Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM/EDX), Attenuated Total Reflection-Fourier Transform Infrared Spectroscopy (ATR-FTIR) and Small Angle X-ray Scattering (SAXS) techniques. The sponge Chondrosia reniformis (Porifera, Demospongiae) lacks a structural skeleton of spicules or the spongin. It consists mainly of a collagenous tissue. The collagen with sponge origin is an important source in biomedical and pharmaceutical applications. The second aim of this study was to provide more information on the molecular structure of collagen of outer (ectosome) and inner (choanosome) regions of the Chondrosia reniformis using ATR-FTIR spectroscopy. Hierarchical clustering analysis (HCA) was also used for the discrimination of ATR-FTIR spectra of species.

AB - In this work, an efficient colorimetric chemosensor for the detection of ethylamines using a pyridinium salt (the Zincke salt) is reported. Highly sensitive and selective reactivity of the Zincke salt enables colorimetric response of the Zincke salt solution to the ethylamines by showing well-defined visible color changes from colorless to the deep red. Furthermore, the Zincke salt thin film exhibits discernable color changes in response to ethylamine gas as well, which allows fabrication of simple, fast and portable strip- and textile type ethylamine sensors. PMID- 29179089 TI - On the rheology of mixed systems of hydrophobically modified polyacrylate microgels and surfactants: Role of the surfactant architecture. AB - HYPOTHESIS: The rheological control of suspensions is of key interest in the formulation design. A chemically cross-linked hydrophobically modified poly(acrylic acid) (HMCL-PAA), used as rheology modifier, is pH sensitive and shows swelling behavior above a critical pH due to the ionization of the acrylic acid groups. At low pH, HMCL-PAA suspensions are liquid and turbid. The binding of surfactants to HMCL-PAA, at low pH conditions, can result in significant changes on rheology and transparency of the polymeric suspensions, due to the swelling of the microgel particles. EXPERIMENTS: The influence of surfactants addition on the rheological properties and transparency of HMCL-PAA suspensions was determined. A systematic study was performed using different types of surfactants (ionic, non-ionic and zwitterionic). FINDINGS: The gelation efficiency of HMCL-PAA suspensions at low pH is strongly dependent on surfactant architecture: ionic surfactants are found to be much more efficient than non ionic or zwitterionic surfactants. Ionic surfactants lead to a liquid-to-gel transition accompanied by an increase of transparency of the suspensions. Among the ionic surfactants, anionics show stronger interactions with the polymer. Also the surfactant hydrophobicity is relevant; the more hydrophobic the surfactant, the stronger is the binding to the polymer and thus the larger the particle swelling. PMID- 29179090 TI - Versatile hollow fluorescent metal-silica nanohybrids through a modified microemulsion synthesis route. AB - Silica-metal nanohybrids are common materials for applications in biomedicine, catalysis or sensing. Also, hollow structures are of interest as they provide additional useful features. However, in these materials the control of the size and accessibility to the inner regions of the structure usually requires complex synthesis procedures. Here we report a simple colloidal procedure for synthesizing hollow silica-metal nanohybrids, driven by the diffusion of metal precursors through the porous silica shell and subsequent reduction in aqueous solutions. The formation of hollow nanoparticles is controlled by the colloidal conditions during synthesis, which affect the ripening of hollow nanoparticles in presence of organosilanes. The modification of the conditions during synthesis affected the growth of silica precursors in presence of fluorescein isothiocyanate (FITC). The limited access to water molecules during the hydrolysis of silica precursors is attributed to the hydrophobicity of organic fluorescent molecules linked to the condensing silica clusters at the initial stages of nanoparticle formation and to the limitation of water content in the microemulsion method used. Finally, the growth of metal nanoseeds at the core of hollow nanoparticles can be easily achieved though a simple method in aqueous environment. The pH and thermal conditions during the reduction process affect the formation of metal-silica nanohybrids and their structural features. PMID- 29179092 TI - Rheology of particle/water/oil three-phase dispersions: Electrostatic vs. capillary bridge forces. AB - HYPOTHESIS: Particle/water/oil three-phase capillary suspensions possess the remarkable property to solidify upon the addition of minimal amount of the second (dispersed) liquid. The hardening of these suspensions is due to capillary bridges, which interconnect the particles (pendular state). Electrostatic repulsion across the oily phase, where Debye screening by electrolyte is missing, could also influence the hardness of these suspensions. EXPERIMENTS: We present data for oil-continuous suspensions with aqueous capillary bridges between hydrophilic SiO2 particles at particle volume fractions 35-45%. The hardness is characterized by the yield stress Y for two different oils: mineral (hexadecane) and vegetable (soybean oil). FINDINGS AND MODELLING: The comparison of data for the "mirror" systems of water- and oil-continuous capillary suspensions shows that Y is lower for the oil-continuous ones. The theoretical model of yield stress is upgraded by including a contribution from electrostatic repulsion, which partially counterbalances the capillary-bridge attraction and renders the suspensions softer. The particle charge density determined from data fits is close to that obtained in experiments with monolayers from charged colloid particles at oil/water interfaces. The results could contribute for better understanding, quantitative prediction and control of the mechanical properties of solid/liquid/liquid capillary suspensions. PMID- 29179091 TI - Facile approach to synthesize highly fluorescent multicolor emissive carbon dots via surface functionalization for cellular imaging. AB - Luminescent nanomaterials are encouraging scaffolds for diverse applications such as chemical sensors and biosensors, imaging, drug delivery, diagnostics, catalysis, energy, photonics, medicine, and so on. Carbon dots (CDs) are a new class of luminescent carbonaceous nanomaterial that have appeared recently and reaped tremendous scientific interest. Herein, we have exploited a simple approach to prepare tuneable and highly fluorescent CDs via surface functionalization. The successful synthesis of CDs is manifested from several investigations like high-resolution transmission electron microscopy (HRTEM), X ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The CDs exhibit excellent water solubility and with increasing nitrogen content fluorescence quantum yield increases whereas cell toxicity decreases. The CD synthesized at high temperature (180 degrees C) shows very high quantum yield (more than 56%). The tuneable optical properties of CDs are systematically studied using UV-vis and fluorescence spectroscopy. The cell viability evaluation and in vitro imaging study reveals that the synthesized CDs can be employed as a potential fluorescent probe for bio-imaging without further modification. PMID- 29179093 TI - Stabilization of spherical nanoparticles of iron(III) hydroxides in aqueous solution by wormlike micelles. AB - HYPOTHESIS: The low Ksp value of Fe(OH)3 (3 * 10-38 at 298 K) explain the immediate coagulation when the pH of a solution of Fe(III) is adjusted to 7. However, stable dispersions of Fe(OH)3 can be formed when the pH is adjusted to 7 in the presence of wormlike micelles formed by cetyltrimethylammonium bromide and sodium salicylate. The formation of a structure containing Fe(OH)3 nanoparticles decorating wormlike micelles is responsible for the high stability of the dispersions. EXPERIMENTS: Fe(OH)3 nanoparticles were obtained by increasing the pH of solutions of cetyltrimethylammonium bromide and Fe(III), previously complexed with salicylate at pH 3. The interaction between nanoparticles and the chains of wormlike micelles was investigated by DLS, SAXS, TEM and Cryo-TEM. FINDINGS: DLS revealed higher scattering contrast and slower diffusion for wormlike micelles in the presence of nanoparticles. These results were interpreted as the decoration of the chains of wormlike micelles by nanoparticles of Fe(OH)3. A pearl-necklace model was successfully used to adjust SAXS curves, revealing nanoparticles with ~3 nm of diameter, spaced ~2 nm apart along the string. This result agrees with TEM and Cryo-TEM images. The formed structure prevents the coagulation of nanoparticles, assuring high stability to the dispersion.

AB - Nickel oxide nanoparticles were deposited on different carbon supports including activated Vulcan XC-72R carbon black (NiO/AC), multi-walled carbon nanotubes (NiO/MWCNTs), graphene (NiO/Gr) and graphite (NiO/Gt) through precipitation step followed by calcination at 400 degrees C. To determine the crystalline structure and morphology of prepared electrocatalysts, X-ray diffraction (XRD) and transmission electron microscopy (TEM) were employed. The electrocatalytic activity of NiO/carbon support electrocatalysts was investigated towards urea electro-oxidation reaction in NaOH solution using cyclic voltammetry, chronoamperometry and electrochemical impedance spectroscopy. Urea oxidation peak current density was increased in the following order: NiO/AC < NiO/MWCNTs < NiO/Gr < NiO/Gt. Chronoamperometry test also showed an increased steady state oxidation current density for NiO/Gt in comparison to other electrocatalysts. The increased activity and stability of NiO/Gt electrocatalyst encourage the application of graphite as an efficient and cost-saving support to carry metal nanoparticles for urea electro-oxidation reaction. PMID- 29179095 TI - Pendant capsule elastometry. AB - We provide a C/C++ software for the shape analysis of deflated elastic capsules in a pendant capsule geometry, which is based on an elastic description of the capsule material as a quasi two-dimensional elastic membrane using shell theory. Pendant capsule elastometry provides a new in situ and non-contact method for interfacial rheology of elastic capsules that goes beyond determination of the Gibbs- or dilational modulus from area-dependent measurements of the surface tension using pendant drop tensiometry, which can only give a rough estimate of the elastic capsule properties as they are based on a purely liquid interface model. Given an elastic model of the capsule membrane, pendant capsule elastometry determines optimal elastic moduli by fitting numerically generated axisymmetric shapes optimally to an experimental image. For each digitized image of a deflated capsule elastic moduli can be determined, if another image of its undeformed reference shape is provided. Within this paper, we focus on nonlinear Hookean elasticity because of its low computational cost and its wide applicability, but also discuss and implement alternative constitutive laws. For Hookean elasticity, Young's surface modulus (or, alternatively, area compression modulus) and Poisson's ratio are determined; for Mooney-Rivlin elasticity, the Rivlin modulus and a dimensionless shape parameter are determined; for neo Hookean elasticity, only the Rivlin modulus is determined, using a fixed dimensionless shape parameter. Comparing results for different models we find that nonlinear Hookean elasticity is adequate for most capsules. If series of images are available, these moduli can be evaluated as a function of the capsule volume to analyze hysteresis or aging effects depending on the deformation history or to detect viscoelastic effects for different volume change rates. An additional wrinkling wavelength measurement allows the user to determine the bending modulus, from which the layer thickness can be derived. We verify the method by analyzing several materials, compare the results to available rheological measurements, and review several applications. We make the software available under the GPL license at github.com/jhegemann/opencapsule. PMID- 29179096 TI - Cross-talk between protein synthesis, energy metabolism and autophagy in cancer. AB - Translation is a pivotal step in the regulation of gene expression as well as one of the most energy consuming processes in the cell. Dysregulation of translation caused by the aberrant function of upstream signaling pathways and/or perturbations in the expression or function of components of the translation machinery is frequent in cancer. In this review, we discuss emerging findings that highlight hitherto unappreciated aspects of signaling to the translation apparatus with the particular focus on emerging connections between protein synthesis, autophagy and energy homeostasis in cancer. PMID- 29179097 TI - Preservation of large yellow croaker (Pseudosciaena crocea) by Coagulin L1208, a novel bacteriocin produced by Bacillus coagulans L1208. AB - Large yellow croaker (Pseudosciaena crocea) is a cultivated fish of great economic importance and abundant nutritional value. However, due to its high protein and water contents, it is susceptible to decomposition, leading to considerable economic loss and adverse effects on consumer health. Here, we assessed the function of the bacterial strain Bacillus coagulans L1208 (Bcoa) in preserving large yellow croaker during storage at 4 degrees C and found that Bcoa elongates the shelf-life significantly. Further investigations showed that Bcoa prolongs the storage time mainly by suppressing the growth of spoilage bacteria. Moreover, a novel bacteriocin, designated as Coagulin L1208 and produced by Bcoa, was purified and identified by N-terminal sequencing. Finally, the activity of Coagulin L1208 for suppressing spoilage bacteria during the preservation of large yellow croaker was assessed. Our results reveal the mechanism by which Bcoa aids the preservation of large yellow croaker and identify Coagulin L1208 as a potential novel antiseptic. PMID- 29179098 TI - The antibacterial activity of clove oil/chitosan nanoparticles embedded gelatin nanofibers against Escherichia coli O157:H7 biofilms on cucumber. AB - This study aims to evaluate the antibacterial activity of clove oil-loaded chitosan nanoparticles (CO@CNPs) and gelatin electrospun nanofibers against Escherichia coli O157:H7 (E. coli O157:H7) biofilms on cucumbers. The optimal CO@CNPs were prepared when the initial concentration of clove oil (CO) was 2.5mg/mL according to the ionic crosslinking method. CO@CNPs showed high antibacterial activity against E. coli O157:H7 biofilms. After 8h treatment, almost 99.98% reduction in E. coli O157:H7 population was achieved when CO@CNPs were applied at 30% (w/v). Subsequently, the prepared CO@CNPs were incorporated successfully within gelatin nanofibers by electrospinning. After 9mg/mL gelatin/CO@CNPs treatment for 24h, the population of E. coli O157:H7 biofilm reduced by about 99.99% in vitro. Further, the application of gelatin/CO@CNPs nanofibers on cucumber against E. coli O157:H7 biofilm was evaluated as well. After 6mg/mL and 9mg/mL gelatin/CO@CNPs nanofibers treatment at 12 degrees C for 4days, 4.28 and 4.97 log10 reductions of E. coli O157:H7 biofilm in population were observed, respectively. Finally, the sensory evaluation results implied that the gelatin/CO@CNPs nanofibers treatment could maintain the color and flavor of cucumber well for >4days. PMID- 29179099 TI - Influence of fermentation and other processing steps on the folate content of a traditional African cereal-based fermented food. AB - Folate deficiency can cause a number of diseases including neural tube defects and megaloblastic anemia, and still occurs in both developed and developing countries. Cereal-based food products are staple foods in many countries, and may therefore be useful sources of folate. The production of folate by microorganisms has been demonstrated in some cereal-based fermented foods, but has never been studied in a traditional African cereal based food spontaneously fermented. The microbiota of ben-saalga, a pearl-millet based fermented porridge frequently consumed in Burkina Faso, has a good genetic potential for the synthesis of folate, but the folate content of ben-saalga is rather low, suggesting that folate is lost during the different processing steps. The aim of this study was therefore to monitor changes in folate content during the different steps of preparing ben-saalga, from pearl-millet grains to porridge. Traditional processing involves seven different steps: washing, soaking, grinding, kneading, sieving, (spontaneous) fermentation, and cooking. Two type of porridge were prepared, one using a process adapted from the traditional process, the other a modified process based on fermentation by backslopping. Dry matter and total folate contents were measured at each step, and a mass balance assessment was performed to follow folate losses and gains. Folate production was observed during the soaking of pearl-millet grains (+26% to +79%), but the folate content of sieved batters (2.5 to 3.4MUg/100g fresh weight) was drastically lower than that of milled soaked grains (17.3 to 19.4MUg/100g FW). The final folate content of the porridges was very low (1.5 to 2.4MUg/100g FW). The fermentation had no significant impact on folate content, whatever the duration and the process used. This study led to a better understanding of the impact on folate of the different processing steps involved in the preparation of ben-saalga.

AB - Despite significant analytical improvements during this last decade, characterizing the whole integrity of monoclonal antibodies during their bioproduction remains a challenge. In this study, we report a new analytical approach to evaluate the overall heterogeneity/integrity of mAbs by LC-MS after combined proteolysis at their lower- and upper-hinge sites using the immunoglobulin-degrading enzymes IdeS and IgdE respectively. The whole sample preparation did not use any harsh conditions such as low pH, high temperature or reductive conditions and enables the splitting of mAbs structure into three fragments, namely the hinge dimer, Fab and Fc/2. Using the NIST mAb reference material, this method was demonstrated to be particularly suited for the analysis of mAbs disulfide bridges. The three fragments as well as their corresponding free sulfhydryl forms were well separated by chromatography and identified online by mass spectrometry. The method was then successfully applied to several mAbs of variable hydrophobicities. PMID- 29179101 TI - The "Cinderella Syndrome": A narrative study of social curfews and lifestyle restrictions in juvenile myoclonic epilepsy. AB - Several factors are thought to contribute to inadequate seizure control in patients with juvenile myoclonic epilepsy (JME), including drug resistance, neuropsychiatric comorbidity, and poor lifestyle choices. Recent evidence supports the existence of frontal lobe microstructural deficits and behavioral changes that may contribute to poor seizure control in a minority of patients. Counseling patients on the importance of adequate sleep hygiene and alcohol restriction is an important part of the management strategy for patients with JME. However, information is lacking on how these lifestyle restrictions impact on patients with JME. We conducted a qualitative descriptive analysis of the social impact of JME on 12 patients, from their own perspective. We identified four prominent themes: the importance of alcohol use as a social "norm", how JME affected relationships, decision making (risk versus consequences), and knowledge imparting control. Given that these restrictions were interpreted by patients as social "curfews", we suggest that the term "Cinderella Syndrome" encapsulates the perceived imperative to be home before midnight. Our findings underscore the importance for clinicians to recognize that in counseling patients with JME about lifestyle adjustments, there may be a significant social consequence unique to this patient group. PMID- 29179102 TI - Electroencephalographic findings in anti-N-methyl-d-aspartate receptor encephalitis in children: A series of 12 patients. AB - OBJECTIVE: Anti-N-methyl-d-aspartate receptor encephalitis (a-NMDARe) is an acute or subacute encephalopathy where electroencephalogram (EEG) is frequently obtained as part of the workup. Although no diagnostic EEG finding has been described so far, the definition of specific or typical patterns might help to distinguish this group among various encephalopathies of childhood. We examined EEG recordings of our patients with a-NMDARe in order to describe the most frequent findings. METHODS: Clinical and laboratory data and digital EEG recordings of 12 pediatric patients diagnosed with a-NMDARe in two major child neurology centers are evaluated. RESULTS: We reviewed 43 EEG recordings from 12 children with a-NMDARe and followed their evolution for a median of 6 (range: 1 60) months. Initial EEG was abnormal in 11/12 patients. The most frequent finding was focal or diffuse slowing of the background rhythm. Generalized rhythmic delta activity, brief rhythmic discharges (BRDs), and occipital intermittent rhythmic delta activity (OIRDA) were seen in two patients each. Diffuse excess beta frequency activity was seen in three patients. Extreme delta brushes were observed in 5/12 (41.7%) patients, disappeared in 4-6months (two patients), or persisted at 10-17months (two patients). Epileptic activity was seen in seven patients (58%) and lateralized periodic discharges in one. On follow-up EEGs, most epileptic activity disappeared in a median of 8months. CONCLUSIONS: A normal EEG is rare in a-NMDARe. Focal or diffuse slowing, epileptic activity, and extreme delta brush are common findings. Epileptic activity in early EEGs do not persists in most patients. Severe diffuse slowing may predict neurological impairment if confirmed in larger series. PMID- 29179103 TI - Factors associated with behavioral problems and cognitive impairment in children with epilepsy of Kinshasa, Democratic Republic of the Congo. AB - BACKGROUND: Behavioral problems and cognitive impairment are common in children with epilepsy (CWE). In sub-Saharan Africa, little is known about these comorbidities particularly their relationships with socioeconomic features. The goal of this study was to identify clinical and socioeconomic factors associated with behavioral problems and cognitive impairment in CWE of Kinshasa (Democratic Republic of the Congo). METHODS: This cross-sectional hospital-based study had included 104 CWE aged 6 to 17years. Behavioral problems were assessed by the child behavior checklist. The Wechsler nonverbal scale of ability was used to assess cognitive impairment. RESULTS: At least one behavioral problem was found in 34.6% of CWE. Internalized problems were increasing with father's age (p=0.034). Externalized problems were increasing with the decreased of mother's age (p=0.009) and with a previous antiepileptic treatment (p=0.032). Total behavioral problems were increasing with a previous antiepileptic treatment (p=0.029). Cognitive impairment was present in 73.3% of CWE. It was more common in boys (p=0.013), and it was increasing with a low household daily expenses (p=0.034), with a previous antiepileptic treatment (p=0.041), with an early onset of epileptic seizures (p=0.042), and with a high frequency of epileptic seizures (p=0.011). CONCLUSION: Behavioral problems and cognitive impairment are common in CWE. Multivariate analysis has shown that behavioral problems were associated with socioeconomic features only. Contrariwise, cognitive impairment was associated with both socioeconomic factors and clinical features. There is a need of more studies to improve knowledge of these comorbidities in the sub-Saharan Africa context. PMID- 29179104 TI - Who are the individuals diagnosed with epilepsy using the Public Health System in the city of Pelotas, southern Brazil? AB - The aim of this study was to describe sociodemographic, clinical, behavioral, nutritional, and health-related variables from people with epilepsy. A descriptive observational study was carried out in the city of Pelotas, southern Brazil. Sociodemographic, clinical, behavioral, nutritional, and health-related variables were collected. A univariate analysis was performed, calculating the measures of central tendency for continuous variables and proportions for categorical ones. The sample consisted of 101 people, age ranging from 12 to 75years, mostly male (50.5%) and white (59.4%). Only 37.2% from the sample was employed, and the average income was R$ 788.00 Brazilian Reais (US$ 245.90 at the moment of the interview). From all the subjects, 65.6% was in treatment with monotherapy, 62.9% presented more than 15 seizures during the life, 67.3% showed active epilepsy, 64.6% were physically inactive, 52.5% presented normal body mass index, and 50% showed generalized seizures. The most used antiepileptic drug was the carbamazepine. The average score of depression was 12.6+/-4.1 points and 34.6% showed severe depressive symptoms (equal or higher than 15 points). The mean score of trait and state anxiety was 12.2+/-3.6 and 15.1+/-3.4 points, respectively (ranging from 6 to 24 points). The mean score of quality of life and stress was 63.2+/-18.2 (ranging from 0 to 100 points) and 21.2+/-7.1 points (ranging from 0 to 40 points), respectively. Considering the medication side effects, the mean score was 42.4+/-8.9 points, 38.5% showing high rates (higher than 45 points), and only 16% showing good sleep quality. In conclusion, these results are important to improve understanding of these individuals' disease and to subsidize the specific public policies in countries of low and middle income. PMID- 29179105 TI - Predicting epileptic seizure control during pregnancy. AB - OBJECTIVE: The objective of the study was to assess whether the type of seizure disorder present in the prospective mother with epilepsy, her use of antiepileptic drugs (AEDs) in early pregnancy, and her seizure control before pregnancy help predict her prospects for seizure freedom throughout pregnancy. METHODS: This paper is based on data accumulated in the Australian Pregnancy Register (APR) between 1998 and late 2016. Information was analyzed concerning epileptic seizure occurrence and AED therapy taken before and during pregnancy, using simple statistical and confidence interval (C.I.) methods, mainly relative risk (R.R.) calculations. RESULTS: After excluding pregnancies lost to follow-up, and those that ended prematurely because of spontaneous abortion or stillbirth, 1939 pregnancies were available for study. Seizures had occurred during pregnancy in 829 (42.8%), and convulsive seizures in 385 (19.9%). Seizures of any type occurred in 78.4% of pregnancies where seizures had occurred in the previous year (active epilepsy) and in 22.3% of those associated with inactive epilepsy. Seizures of any type had occurred in 54.9% of pregnancies initially unexposed to AEDs and in 45.5% of those treated with AEDs throughout. The corresponding figures for convulsive seizures during pregnancy were 31.7% and 22.3%. There was statistically significant evidence that, in women with epilepsy (WWE), having a seizure disorder that was active in the prepregnancy year and one untreated in early pregnancy was associated with decreased prospects of seizure freedom during pregnancy. Decreased chances of seizure-free pregnancies in women with focal epilepsies and those treated with multiple AEDs were probably explained by greater frequencies of active seizure disorders in these patient categories. CONCLUSIONS: Women with epilepsy who experience seizures in the year prior to pregnancy appear 3 or 4 times more likely to continue to have seizures during pregnancy than women whose seizures are fully controlled prior to pregnancy. Not taking AEDs in early pregnancy also increases the hazard for seizure occurrence in pregnancy. PMID- 29179106 TI - Quality of life in adults with epilepsy is associated with anticonvulsant polypharmacy independent of seizure status. AB - RATIONALE: Polypharmacy, sometimes necessary to control epilepsy, can result in adverse effects that may affect quality of life (QOL). Our purpose was to determine the association of polypharmacy with QOL. METHODS: Two hundred seven patients with epilepsy were surveyed on characteristics within the last 4weeks: QOL Quality of Life in Epilepsy-Patient-Weighted (QOLIE-10-P) and seizure status (seizure-free or not), demographics, epilepsy characteristics, insomnia, sleepiness, mood, sleep-wake timing, healthcare use, and employment. Those on polypharmacy (antiepileptic drug (AED)>1) were compared with controls (AED=1) with univariate comparisons and subsequent multivariate regression. RESULTS: Patients on polypharmacy had worse QOL scores (mean 33.3+/-6.9 versus 36.7+/ 5.7), were less likely to be seizure-free (39 (44%) versus 82 (68%)), had more evening-weighted wakefulness, and were more likely unemployed (74% versus 49%). Polypharmacy was associated with worse QOL (odds ratio 1.068 and 95th CI 1.018 1.121) even after controlling for seizure status. Covariates offered no improvement to the model. CONCLUSION: Polypharmacy was associated with worse QOL in patients with epilepsy despite seizure control. Further investigation into specific etiology of polypharmacy's influence on QOL is warranted in order to develop paradigms for optimal treatment. PMID- 29179107 TI - Local redox environment beneath biological membranes probed by palmitoylated roGFP. AB - Production of reactive oxygen species (ROS) and consequent glutathione oxidation are associated with various physiological processes and diseases, including cell differentiation, senescence, and inflammation. GFP-based redox sensors provide a straight-forward approach to monitor ROS levels and glutathione oxidation within a living cell at the subcellular resolution. We utilized palmitoylated versions of cytosolic glutathione and hydrogen peroxide sensors (Grx1-roGFP2 and roGFP2 Orp1, respectively) and demonstrated a unique redox environment near biological membranes. In HeLa cells, cytosolic glutathione was practically completely reduced (EGSH/GSSG = - 333mV) and hydrogen peroxide level was under the detectable range. In contrast, the cytoplasmic milieu near membranes of intracellular vesicles exhibited significant glutathione oxidation (EGSH/GSSG > - 256mV) and relatively high H2O2 production, which was not observed for the plasma membrane. These vesicles colocalized with internalized EGFR, suggesting that H2O2 production and glutathione oxidation are characteristics of cytoplasmic surfaces of the endocytosed vesicles. The results visually illustrate local redox heterogeneity within the cytosol for the first time. PMID- 29179109 TI - Bacterial nitrogen fixation in sand bioreactors treating winery wastewater with a high carbon to nitrogen ratio. AB - Heterotrophic bacteria proliferate in organic-rich environments and systems containing sufficient essential nutrients. Nitrogen, phosphorus and potassium are the nutrients required in the highest concentrations. The ratio of carbon to nitrogen is an important consideration for wastewater bioremediation because insufficient nitrogen may result in decreased treatment efficiency. It has been shown that during the treatment of effluent from the pulp and paper industry, bacterial nitrogen fixation can supplement the nitrogen requirements of suspended growth systems. This study was conducted using physicochemical analyses and culture-dependent and -independent techniques to ascertain whether nitrogen fixing bacteria were selected in biological sand filters used to treat synthetic winery wastewater with a high carbon to nitrogen ratio (193:1). The systems performed well, with the influent COD of 1351 mg/L being reduced by 84-89%. It was shown that the nitrogen fixing bacterial population was influenced by the presence of synthetic winery effluent in the surface layers of the biological sand filters, but not in the deeper layers. It was hypothesised that this was due to the greater availability of atmospheric nitrogen at the surface. The numbers of culture-able nitrogen-fixing bacteria, including presumptive Azotobacter spp. exhibited 1-2 log increases at the surface. The results of this study confirm that nitrogen fixation is an important mechanism to be considered during treatment of high carbon to nitrogen wastewater. If biological treatment systems can be operated to stimulate this phenomenon, it may obviate the need for nitrogen addition. PMID- 29179110 TI - LAND-deFeND - An innovative database structure for landslides and floods and their consequences. AB - Information on historical landslides and floods - collectively called "geo hydrological hazards - is key to understand the complex dynamics of the events, to estimate the temporal and spatial frequency of damaging events, and to quantify their impact. A number of databases on geo-hydrological hazards and their consequences have been developed worldwide at different geographical and temporal scales. Of the few available database structures that can handle information on both landslides and floods some are outdated and others were not designed to store, organize, and manage information on single phenomena or on the type and monetary value of the damages and the remediation actions. Here, we present the LANDslides and Floods National Database (LAND-deFeND), a new database structure able to store, organize, and manage in a single digital structure spatial information collected from various sources with different accuracy. In designing LAND-deFeND, we defined four groups of entities, namely: nature related, human-related, geospatial-related, and information-source-related entities that collectively can describe fully the geo-hydrological hazards and their consequences. In LAND-deFeND, the main entities are the nature-related entities, encompassing: (i) the "phenomenon", a single landslide or local inundation, (ii) the "event", which represent the ensemble of the inundations and/or landslides occurred in a conventional geographical area in a limited period, and (iii) the "trigger", which is the meteo-climatic or seismic cause (trigger) of the geo-hydrological hazards. LAND-deFeND maintains the relations between the nature-related entities and the human-related entities even where the information is missing partially. The physical model of the LAND-deFeND contains 32 tables, including nine input tables, 21 dictionary tables, and two association tables, and ten views, including specific views that make the database structure compliant with the EC INSPIRE and the Floods Directives. The LAND-deFeND database structure is open, and freely available from http://geomorphology.irpi.cnr.it/tools. PMID- 29179108 TI - A hypermorphic antioxidant response element is associated with increased MS4A6A expression and Alzheimer's disease. AB - Late onset Alzheimer's disease (AD) is a multifactorial disorder, with AD risk influenced by both environmental and genetic factors. Recent genome-wide association studies (GWAS) have identified genetic loci associated with increased risk of developing AD. The MS4A (membrane-spanning 4-domains subfamily A) gene cluster is one of the most significant loci associated with AD risk, and MS4A6A expression is correlated with AD pathology. We identified a single nucleotide polymorphism, rs667897, at the MS4A locus that creates an antioxidant response element and links MS4A6A expression to the stress responsive Cap-n-Collar (CNC) transcription factors NRF1 (encoded by NFE2L1) and NRF2 (encoded by NFE2L2). The risk allele of rs667897 generates a strong CNC binding sequence that is activated by proteostatic stress in an NRF1-dependent manner, and is associated with increased expression of the gene MS4A6A. Together, these findings suggest that the cytoprotective CNC regulatory network aberrantly activates MS4A6A expression and increases AD risk in a subset of the population. PMID- 29179111 TI - Investigation of the interaction between the fate of antibiotics in aquafarms and their level in the environment. AB - China is the largest freshwater aquaculture producer and antibiotics consumer in the world, and rivers in China are generally polluted by antibiotics. However, there is little information available regarding the linkage of antibiotics in aquaculture and the aquatic environment. Therefore, this study investigated the fate of antibiotics in several open water culture-based freshwater aquafarms, including integrated livestock/fish systems and non-integrated fish ponds, and explored the contamination profiles of antibiotics in the Beijiang River. Then the study tried to clarify the two-way interaction of antibiotics in aquaculture and the environment. The results showed that, when compared with the effluent from livestock farms and wastewater treatment plants, the contribution of antibiotics from non-integrated fish pond water without livestock sewage input was limited, while that of effluent from the integrated livestock/fish system was quite high. The total concentrations of antibiotics detected in the aquafarm source water were similar to those in the upper river water and generally higher than those in the corresponding fish pond water, implying that the occurrence of antibiotics in intensive aquafarms can mainly be attributed to the antibiotic residues in nearby river water. Overall, the results underscore the need to develop a sewage infrastructure for the treatment of effluent from integrated livestock/fish aquafarms, and suggest that open water culture-based fish farms should be located far from seriously contaminated sections of rivers. PMID- 29179112 TI - Participatory assessment of soil erosion severity and performance of mitigation measures using stakeholder workshops in Koga catchment, Ethiopia. AB - Farmers possess a wealth of knowledge regarding soil erosion and soil and water conservation (SWC), and there is a great demand to access it. However, there has been little effort to systematically document farmers' experiences and perceptions of SWC measures. Sustainable Land Management (SLM) has largely evolved through local traditional practices rather than adoption based on scientific evidence. This research aimed to assess soil erosion and performance of different SWC measures from the farmers' perspective by documenting their perceptions and experiences in Koga catchment, Ethiopia. To this aim, workshops were organised in three sub-catchments differing in slopes and SWC measures. Workshops included group discussions and field monitoring of erosion indicators and systematically describing the status of soil erosion, soil fertility and yield to assess the performance of SWC measures. Results show that farmers are aware of the harmful effects of ongoing soil erosion and of the impacts of mitigation measures on their farms. Sheet erosion was found to be the most widespread form of erosion while rill damage was critical on plots cultivated to cereals on steep slopes. The average rill erosion rates were 24.2 and 47.3 t/ha/y in treated and untreated farmlands, respectively. SWC reduced rill erosion on average by more than 48%. However, the impacts of SWC measures varied significantly between sub-watersheds, and farmers believed that SWC measures did not prevent erosion completely. Comparatively, graded stone-faced soil bunds revealed maximum desired impacts and were most appreciated by farmers, whereas level bunds caused water logging. Most traditional ditches were highly graded and begun incising and affected production of cereals. Despite the semi-quantitative nature of the methodology, using farmers' perceptions and experiences to document land degradation and the impacts of SWC measures is crucial as they are the daily users of the land and therefore directly affecting the success or failure of SWC measures. PMID- 29179113 TI - Effects of pH dynamics on solidification/stabilization of municipal solid waste incineration fly ash. AB - Fly ash (FA), a product of municipal solid waste incineration (MSWI), has been classified as a kind of hazardous waste due to its high content of heavy metals. FA may be reused in the construction industry or disposed of at landfill sites, and thus poses threats to both the environment and human health. This study sought to establish a scientific basis for accurate selection of suitable pH storage conditions for the FA. We evaluated the potential of MSWI FA sample from the Xinghuo waste incineration power plant, Wuhan, to solidify/stabilize the heavy metal (Cu, Pb, Zn, Cr, Cd, As and Mn) contents, when leached under different pH conditions. The concentration of a heavy metal in the leachate was assumed to inversely reflect the extent of its solidification/stabilization (S/S). The study findings showed that the raw FA contained higher levels of the heavy metals, which were above the acceptable limits. Extremely acidic conditions favoured heavy metal leaching compared to extremely alkaline conditions. The extent of S/S of heavy metals was generally very low under highly acidic conditions (pH <= 4), but increased with increasing pH. All the metals solidified/stabilized in pH media of 5-11, except Zn which was detected in the entire pH range. We conclude that changing landfill conditions which can affect the pH environment, will increase heavy metal leaching when the pH <= 4. As a result, waste which was initially classified as non-hazardous may later pose harmful risks to both humans and the environment alike. We propose pH of 5-11 as the optimum pH range for the treatment, reuse, and disposal of the ash sample. PMID- 29179114 TI - Valorization of Poly (ethylene) terephthalate (PET) wastes into magnetic carbon for adsorption of antibiotic from water: Characterization and application. AB - Waste Polyethylene terephthalate (PET) bottles were pyrolyzed in the presence of nitrogen and converted into activated carbon (PETAC) by physical activation in carbon dioxide flow. An ex-situ precipitation and external reduction method were applied for the intercalation of ferromagnetic iron oxides onto the PETAC matrix. The characteristic structural and chemical properties of PETAC and magnetic PETAC (M-PETAC) were studied by Brunauer Emmett Teller (BET) surface area analysis, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Fourier Transform Infrared (FTIR) analysis, Raman spectroscopy, X-Ray Diffraction (XRD) analysis, Energy Dispersive analysis of X-rays (EDAX), Vibrating Sample Magnetometer (VSM), Thermal gravimetric analysis (TGA) and elemental analysis. Characterization results indicated that PETAC exhibited a relatively smooth and microporous texture with a surface area of 659.6 m2g-1 while M-PETAC displayed a rugged morphology with a diminished surface area of 288.8 m2g-1. XRD measurements confirmed the formation of iron oxide nanocrystallites with an average Scherrer crystallite size of 19.2 nm. M-PETAC delivered a quick response to an external magnet and exhibited saturation magnetization value of 35.4 emu g-1. PETAC and M PETAC were explored as potential adsorbents for the adsorption of a pharmaceutical (cephalexin) from water. Isotherm analysis revealed that M-PETAC exhibited a superior adsorption capacity (71.42 mg g-1) compared to PETAC (21.27 mg g-1). FTIR analysis of the adsorbents after CEX adsorption revealed the role of FeO as the nucleation site for enhanced adsorption of cephalexin by M-PETAC. PMID- 29179115 TI - An evaluative tool for rapid assessment of derelict vessel effects on coastal resources. AB - Derelict vessels impact coastal and estuarine habitats, fisheries resources, are aesthetically unappealing, and may be a hazard to navigation and recreation. The Government Accountability Office estimated in 2013 over 5600 derelict vessels existed throughout the coastal United States. Considering the large number of derelict vessels present in coastal areas, effective tools are needed to assess the environmental damage exerted by derelict vessels and aid in management strategies for their removal. After carefully reviewing regulations, we developed a 100-point scoring rubric (DVET) to evaluate damage by derelict vessels to natural resources with minimal field effort. The DVET's ability to rapidly assess a derelict vessel's impact on surrounding natural resources was confirmed with additional rigorous sampling and suggest environmental enhancement following vessel removal. The DVET shows promise for informing derelict vessel removal strategies, although more work is needed to quantify environmental benefits of derelict vessel removal and establish guidelines for removal prioritization. PMID- 29179116 TI - Evaluation of fly ash pellets for phosphorus removal in a laboratory scale denitrifying bioreactor. AB - Nitrate and orthophosphate from agricultural activities contribute significantly to nutrient loading in surface water bodies around the world. This study evaluated the efficacy of woodchips and fly ash pellets in tandem to remove nitrate and orthophosphate from simulated agricultural runoff in flow-through tests. The fly ash pellets had previously been developed specifically for orthophosphate removal for this type of application, and the sorption bench testing showed a good promise for flow-through testing. The lab-scale horizontal flow bioreactor used in this study consisted of an upstream column filled with woodchips followed by a downstream column filled with fly ash pellets (3 and 1 m lengths, respectively; both 0.15 m diameter). Using influent concentrations of 12 mg/L nitrate and 5 mg/L orthophosphate, the woodchip bioreactor section was able to remove 49-85% of the nitrate concentration at three hydraulic retention times ranging from 0.67 to 4.0 h. The nitrate removal rate for woodchips ranged from 40 to 49 g N/m3/d. Higher hydraulic retention times (i.e., smaller flow rates) corresponded with greater nitrate load reduction. The fly ash pellets showed relatively stable removal efficiency of 68-75% across all retention times. Total orthophosphate adsorption by the pellets was 0.059-0.114 mg P/g which was far less than the saturated capacity (1.69 mg/g; based on previous work). The fly ash pellets also removed some nitrate and the woodchips also removed some orthophosphate, but these reductions were not significant. Overall, woodchip denitrification followed by fly ash pellet P-sorption can be an effective treatment technology for nitrate and phosphate removal in subsurface drainage. PMID- 29179117 TI - Investigation of kinetics and absorption isotherm models for hydroponic phytoremediation of waters contaminated with sulfate. AB - Two common wetland plants, Pampas Grass (Cortaderia selloana) and Lucky Bamboo (Dracaena sanderiana), were used in hydroponic cultivation systems for the treatment of simulated high-sulfate wastewaters. Plants in initial experiments at pH 7.0 removed sulfate more efficiently compared to the same experimental conditions at pH 6.0. Results at sulfate concentrations of 50, 200, 300, 600, 900, 1200, 1500 and 3000 mg/L during three consecutive 7-day treatment periods with 1-day rest intervals, showed decreasing trends of both removal efficiencies and uptake rates with increasing sulfate concentrations from the first to the second to the third 7-day treatment periods. Removed sulfate masses per unit dry plant mass, calculated after 23 days, showed highest removal capacity at 600 mg/L sulfate for both plants. A Langmuir-type isotherm best described sulfate uptake capacity of both plants. Kinetic studies showed that compared to pseudo first order kinetics, pseudo-second order kinetic models slightly better described sulfate uptake rates by both plants. The Elovich kinetic model showed faster rates of attaining equilibrium at low sulfate concentrations for both plants. The dimensionless Elovich model showed that about 80% of sulfate uptake occurred during the first four days' contact time. Application of three 4-day contact times with 2-day rest intervals at high sulfate concentrations resulted in slightly higher uptakes compared to three 7-day contact times with 1-day rest intervals, indicating that pilot-plant scale treatment systems could be sized with shorter contact times and longer rest-intervals. PMID- 29179118 TI - Performance improvement of a thermophilic sulfate-reducing bioreactor under acidogenic conditions: Effects of diversified operating strategies. AB - The establishment of a sulfidogenic environment under thermophilic (55 degrees C) acidogenic conditions was assessed in an innovative structured-bed bioreactor to enhance sulfate removal and acetate production prior to methanogenesis. Diversified operating strategies, i.e., variations in the hydraulic retention time (HRT; 6-12 h), sulfate loading rate (SLR; 8-16 kg SO42- m-3 day-1) and liquid phase recirculation ratio (0.0-57.0) were assessed to both enable the establishment of sulfate-reducing conditions and remove H2S from the liquid phase. Ethanol was used as the only carbon source. Applying a low HRT (6 h) as the initial operating strategy severely hindered the establishment of sulfate reducing bacteria (SRB) populations within the system (sulfate removal < 27.5%). In turn, applying effluent recirculation had a positive impact on the system (sulfate removal ~ 60%) by providing an adequate buffer control along the entire height of the system, as well by displacing over 70% of the H2S to the gaseous phase. The maintenance of pH values above 6.1 proved to be adequate for the sulfidogenic activity, whereas enhanced acidic conditions (pH < 6.0) at the basal portion of the reactor comprised a determining factor to hinder sulfate reduction. SRB were able to handle H2S and acetate concentrations as high as 232 mg L-1 and 3111 mg L-1, respectively, after establishing an effective acidogenic/sulfidogenic environment, indicating that the proposed system has the potential to be used as the first stage in the anaerobic processing of sulfate rich wastewater streams. PMID- 29179119 TI - Planning support tools and their effects in participatory urban adaptation workshops. AB - In the face of a changing climate, many cities are engaged in adaptation planning and are using participatory workshops to involve stakeholders in these initiatives. Different tools are being used to structure the process and content of participatory planning workshops, but it is unclear what effect the tools have on the workshops and their results. We evaluated three different tools (Group Model Building, the Adaptation Support Tool, and the Stress Test Guideline) and a tool-free approach in repeated simulated workshops, to observe and compare (1) the way workshops played out, and (2) the direct outcomes that were achieved. Tools appear to influence both aspects. Specifically, we measured differences in the learning effects in groups, in the development of shared understanding within groups, in the types of plans that are developed by groups, and in the nature of participation during the workshops. Further research is needed to translate these results into practice, but this is a first step in advancing knowledge about the influence of tools in participatory planning activities. PMID- 29179120 TI - Metal-homeostasis in the pathobiology of the opportunistic human fungal pathogen Aspergillus fumigatus. AB - In contrast to obligate pathogens opportunistic pathogens such as Aspergillus fumigatus do not need a specific host to propagate or survive. However several characteristics of the saprophytic life-style and the selective pressure encountered in the primary ecological niche contribute to the virulence of A. fumigatus. All fungi depend on metals for growth and proliferation, like iron, copper, zinc, manganese or calcium. In the recent past several studies explored the manifold impact of metals modulating virulence of pathogens. Components which might be scarce in the natural environment but also in the host due to nutritional immunity. This review recapitulates molecular constituents of metal ion uptake systems in A. fumigatus, their regulation and their significance at the host-pathogen battlefield. PMID- 29179121 TI - Antibody biosensors for spoilage yeast detection based on impedance spectroscopy. AB - Brettanomyces is a yeast species responsible for wine and cider spoilage, producing volatile phenols that result in off-odors and loss of fruity sensorial qualities. Current commercial detection methods for these spoilage species are liable to frequent false positives, long culture times and fungal contamination. In this work, an interdigitated (IDE) biosensor was created to detect Brettanomyces using immunological reactions and impedance spectroscopy analysis. To promote efficient antibody immobilization on the electrodes' surface and to decrease non-specific adsorption, a Self-Assembled Monolayer (SAM) was developed. An impedance spectroscopy analysis, over four yeast strains, confirmed our device's increased efficacy. Compared to label-free sensors, antibody biosensors showed a higher relative impedance. The results also suggested that these biosensors could be a promising method to monitor some spoilage yeasts, offering an efficient alternative to the laborious and expensive traditional methods.

This study investigated the impacts of water quality on iron release, dissolved oxygen consumption (DeltaDO), corrosion scale evolution and bacterial community succession in cast iron pipes used for drinking water distribution at pilot scale, and proposed a source water switch strategy accordingly. Three sets of old cast iron pipe section (named BP, SP and GP) were excavated on site and assembled in a test base, which had historically transported blended water, surface water and groundwater, respectively. Results indicate that an increasing Cl- or SO42- concentration accelerated iron release, but alkalinity and calcium hardness exhibited an opposite tendency. Disinfectant shift from free chlorine to monochloramine slightly inhibited iron release, while the impact of peroxymonosulfate depended on the source water historically transported in the test pipes. The DeltaDO was highly consistent with iron release in all three pipe systems. The mass ratio of magnetite to goethite in the corrosion scales of SP was higher than those of BP and GP and kept almost unchanged over the whole operation period. Siderite and calcite formation confirmed that an increasing alkalinity and hardness inhibited iron release. Iron-reducing bacteria decreased in the BP but increased in the SP and GP; meanwhile, sulfur-oxidizing, sulfate reducing and iron oxidizing bacteria increased in all three pipe systems. To avoid the occurrence of "red water", a source water switch strategy was proposed based on the difference between local and foreign water qualities.

AB - California has one of the largest systems of surface water reservoirs in the world, providing irrigation water to California's agriculturally productive Central Valley. Irrigation water is recognized as a vehicle for the microbial contamination of raw produce and must be monitored according to new federal regulation. The purpose of this study was to further understanding of the variability of fecal indicator bacteria (Escherichia coli and fecal coliforms) and pathogens (E. coli O157:H7 (O157), non-O157 Shiga toxin-producing E. coli (STEC) and Salmonella) along both horizontal and vertical profiles within California reservoirs. Monthly sampling was conducted in six reservoirs located in the foothills of the Western Sierra Nevada during the summer irrigation season and extreme drought conditions of 2014 (n = 257). Concentrations of fecal indicator bacteria were highly variable between reservoirs (p < 0.05) and along the horizontal profile (p < 0.001) from upstream to downstream, with higher concentrations typically found outside of the reservoirs than within. Though many of the reservoirs were thermally stratified, bacterial concentrations were not associated with water temperature (p > 0.05) or any one particular depth strata (p < 0.05). However, prevalence of Salmonella and STEC (16/70 and 9/70 respectively) was higher in the deep strata than in mid or surface layers. We found no statistical association between samples collected downstream of reservoirs and those from the reservoirs themselves. Continued monitoring and modeling of both bacterial indicators and enteric pathogens are critical to our ability to estimate the risk of surface irrigation water supplies and make appropriate management decisions.

AB - Shale gas produced water (SGPW) treatment imposes greater technical challenges because of its high concentration of various contaminants. Membrane distillation crystallization (MDC) has a great potential to manage SGPW since it is capable of recovering both water and minerals at high rates, up to near a zero liquid discharge (ZLD) condition. To evaluate the feasibility of MDC for SGPW treatment, MDC performance indicators, such as water recovery rate, solid production rate (SPR) and specific energy consumption (SEC), were systematically investigated, to our knowledge for the first time, by using actual SGPW from Eagle Ford Shale (USA). The main operating parameters including feed cross-flow velocity (CFV) and crystallization temperature (TCr) were optimized by performing a series of MDC experiments. The results reported that water and minerals were effectively recovered with 84% of recovery rate and 2.72 kg/m2day of SPR under respective optimal operating conditions. Furthermore, the scale mechanism was firstly identified as limiting factor for MDC performance degradation. Lastly, SEC of MDC was estimated to be as low as 28.2 kWh/m3 under ideal optimal operating conditions. Our experimental observations demonstrated that MDC could sustainably and effectively recover water and mineral with low energy consumption from SGPW by optimizing operating condition.

AB - Youth sport is a key developmental context for many reasons, including the opportunities it provides for building relationships with peers and its potential to support character development. Peers can influence adolescent sport experiences and shape their motivations, and different peer motivational climates may differentially support athlete character. Established models identify different dimensions of peer motivational climate, yet these models do not describe how aspects of peer climate may align with character. We therefore assess profiles of peer motivational climate in relation to a multi-dimensional practitioner-developed theoretical model for character development through sport. Participants were 655 adolescent athletes from the greater Boston area, in the United States. Athletes perceiving a mastery-involved peer climate, even with high intra-team competition, were most likely to exhibit positive character attributes at the three levels of character assessed: themselves, their teammates, and the game. This study also demonstrates the utility of practitioner developed models for adolescent research. PMID- 29179126 TI - Adolescent health literacy and health behaviors: A systematic review. AB - OBJECTIVES: To systematically review and synthesize literature on the relationship between health literacy and health behaviors in adolescents. METHODS: Searches in PsychInfo, PUBMED/MEDLINE, and Educational Resources Information Center (ERIC) were conducted. Studies were included if they reported original data on the relationship between health literacy and a health behavior in adolescents, were written in English, and the population did not have a chronic illness or disability. RESULTS: Seventeen studies met inclusionary criteria. Definition and measurement of health literacy, and theoretical frameworks varied across studies. Studies investigated the relationship between functional and media health literacy and adolescent health behaviors, thirteen reported significant, linear relationships. CONCLUSIONS: The results suggest that there is a meaningful relationship between health literacy and adolescents' health behaviors. To fully understand the role of health literacy in adolescents' health decision-making, future research should use comprehensive definitions and measures of health literacy, and integrate health behavior and adolescent development theoretical frameworks in study design. PMID- 29179127 TI - From TBT to booster biocides: Levels and impacts of antifouling along coastal areas of Panama. AB - Antifouling biocides in surface sediments and gastropod tissues were assessed for the first time along coastal areas of Panama under the influence of maritime activities, including one of the world's busiest shipping zones: the Panama Canal. Imposex incidence was also evaluated in five muricid species distributed along six coastal areas of Panama. This TBT-related biological alteration was detected in three species, including the first report in Purpura panama. Levels of organotins (TBT, DBT, and MBT) in gastropod tissues and surficial sediments ranged from <5 to 104 ng Sn g-1 and <1-149 ng Sn g-1, respectively. In addition, fresh TBT inputs were observed in areas considered as moderate to highly contaminated mainly by inputs from fishing and leisure boats. Regarding booster biocides, TCMTB and dichlofluanid were not detected in any sample, while irgarol 1051, diuron and DCOIT levels ranged from <0.08 to 2.8 ng g-1, <0.75-14.1 ng g-1, and <0.38-81.6 ng g-1, respectively. The highest level of TBT (149 ng Sn g-1) and irgarol 1051 (2.8 ng g-1), as well as relevant level of DCOIT (5.7 ng g-1), were detected in a marina used by recreational boats. Additionally, relatively high diuron values (14.1 ng g-1) were also detected in the Panama Canal associate to a commercial port. DCOIT concentrations were associated with the presence of antifouling paint particles in sediments obtained nearby shipyard or boat maintenance sites. The highest levels of TBT, irgarol 1051, and diuron exceeded international sediment quality guidelines indicating that toxic effects could be expected in coastal areas of Panama. Thus, the simultaneous impacts produced by new and old generations of antifouling paints highlight a serious environmental issue in Panamanian coastal areas. PMID- 29179128 TI - Historical legacies of river pollution reconstructed from fish scales. AB - Many rivers have been impacted by heavy metal pollution in the past but the long term legacies on biodiversity are difficult to estimate. The River Ulla (NW Spain) was impacted by tailings from a copper mine during the 1970-1980s but absence of baseline values and lack of subsequent monitoring have prevented a full impact assessment. We used archived fish scales of Atlantic salmon to reconstruct levels of historical copper pollution and its effects on salmon fitness. Copper bioaccumulation significantly increased over baseline values during the operation of the mine, reaching sublethal levels for salmon survival. Juvenile growth and relative population abundance decreased during mining, but no such effects were observed in a neighbouring river unaffected by mining. Our results indicate that historical copper exposure has probably compromised the fitness of this Atlantic salmon population to the present day, and that fish scales are suitable biomarkers of past river pollution. PMID- 29179129 TI - Multivariate statistical analysis to characterize/discriminate between anthropogenic and geogenic trace elements occurrence in the Campania Plain, Southern Italy. AB - Shallow aquifers are the most accessible reservoirs of potable groundwater; nevertheless, they are also prone to various sources of pollution and it is usually difficult to distinguish between human and natural sources at the watershed scale. The area chosen for this study (the Campania Plain) is characterized by high spatial heterogeneities both in geochemical features and in hydraulic properties. Groundwater mineralization is driven by many processes such as, geothermal activity, weathering of volcanic products and intense human activities. In such a landscape, multivariate statistical analysis has been used to differentiate among the main hydrochemical processes occurring in the area, using three different approaches of factor analysis: (i) major elements, (ii) trace elements, (iii) both major and trace elements. The elaboration of the factor analysis approaches has revealed seven distinct hydrogeochemical processes: i) Salinization (Cl-, Na+); ii) Carbonate rocks dissolution; iii) Anthropogenic inputs (NO3-, SO42-, U, V); iv) Reducing conditions (Fe2+, Mn2+); v) Heavy metals contamination (Cr and Ni); vi) Geothermal fluids influence (Li+); and vii) Volcanic products contribution (As, Rb). Results from this study highlight the need to separately apply factor analysis when a large data set of trace elements is available. In fact, the impact of geothermal fluids in the shallow aquifer was identified from the application of the factor analysis using only trace elements. This study also reveals that the factor analysis of major and trace elements can differentiate between anthropogenic and geogenic sources of pollution in intensively exploited aquifers. PMID- 29179130 TI - Predictive bioinformatics identifies novel regulators of proliferation in a cancer stem cell model. AB - The cancer stem cell model postulates that tumors are hierarchically organized with a minor population, the cancer stem cells, exhibiting unlimited proliferative potential. These cells give rise to the bulk of tumor cells, which retain a limited ability to divide. Without successful targeting of cancer stem cells, tumor reemergence after therapy is likely. However, identifying target pathways essential for cancer stem cell proliferation has been challenging. Here, using a transcriptional network analysis termed GAMMA, we identified 50 genes whose correlation patterns suggested involvement in cancer stem cell division. Using RNAi depletion, we found that 21 of these target genes showed preferential growth inhibition in a breast cancer stem cell model. More detailed initial analysis of 6 of these genes revealed 4 with clear roles in the fidelity of chromosome segregation. This study reveals the strong predictive potential of transcriptional network analysis in increasing the efficiency of successful identification of novel proliferation dependencies for cancer stem cells. PMID- 29179131 TI - Engineering detoxified pneumococcal pneumolysin derivative DeltaA146PLY for self biomineralization of calcium phosphate: Assessment of their protective efficacy in murine infection models. AB - Vaccine design ushered in the era of nanotechnology, as the vaccine is being developed toward particulate formulation. We have previously shown that the attenuated pneumolysin mutant (DeltaA146PLY) was a safe and effective pneumococcal vaccine candidate. Here, to further optimize the formulation, we fused calcium phosphate (CaP) binding domains with DeltaA146PLY so that the biocompatible CaP can mineralize with the protein automatically, allowing simple production of nanoparticle antigen during preparation. We fabricated four different nanoparticles, and then we compared the characteristics of different CaP-DeltaA146PLY nanoparticles and demonstrated the influence of CaP binding domains on the size, shape and surface calcium content of the nanoparticles. It was found that these self-biomineralized CaP-DeltaA146PLY nanoparticles varied in their capacity to induce BMDCs and splenocytes production of cytokines. We further demonstrated that, compared to free proteins, nanoparticle antigens induced more efficient humoral and cellular immune responses which was strong enough to protect mice from both pneumonia and sepsis infection. Also, the integration of CaP to protein has no significant impairment on body weight of animals, and subcutaneous injection of DeltaA146PLY-peptides@CaP nanoparticles did not lead to permanent formation of nodules in the skin relative to Alum adjuvant formulated antigens. Together, our data sufficiently suggest that soluble DeltaA146PLY vaccine candidate could be processed into nanoparticles by self-biomineralization of CaP, the immunogenicity of which could be efficiently improved by the CaP binding domains and biomineralization. PMID- 29179132 TI - Rational incorporation of molecular adjuvants into a hybrid nanoparticle-based nicotine vaccine for immunotherapy against nicotine addiction. AB - Current clinically-tested nicotine vaccines have yet shown enhanced smoking cessation efficacy due to their low immunogenicity. Achieving a sufficiently high immunogenicity is a necessity for establishing a clinically-viable nicotine vaccine. This study aims to facilitate the immunogenicity of a hybrid nanoparticle-based nicotine vaccine by rationally incorporating toll-like receptor (TLR)-based adjuvants, including monophosphoryl lipid A (MPLA), Resiquimod (R848), CpG oligodeoxynucleotide 1826 (CpG ODN 1826), and their combinations. The nanoparticle-delivered model adjuvant was found to be taken up more efficiently by dendritic cells than the free counterpart. Nanovaccine particles were transported to endosomal compartments upon cellular internalization. The incorporation of single or dual TLR adjuvants not only considerably increased total anti-nicotine IgG titers but also significantly affected IgG subtype distribution in mice. Particularly, the nanovaccines carrying MPLA+R848 or MPLA+ODN 1826 generated a much higher anti-nicotine antibody titer than those carrying none or one adjuvant. Meanwhile, the anti nicotine antibody elicited by the nanovaccine adjuvanted with MPLA+R848 had a significantly higher affinity than that elicited by the nanovaccine carrying MPLA+ODN 1826. Moreover, the incorporation of all the selected TLR adjuvants (except MPLA) reduced the brain nicotine levels in mice after nicotine challenge. Particularly, the nanovaccine with MPLA+R848 exhibited the best ability to reduce the level of nicotine entering the brain. Collectively, rational incorporation of TLR adjuvants could enhance the immunological efficacy of the hybrid nanoparticle based nicotine vaccine, making it a promising next-generation immunotherapeutic candidate for treating nicotine addiction. PMID- 29179135 TI - No improvement in long-term survival for epithelial ovarian cancer patients: A population-based study between 1989 and 2014 in the Netherlands. AB - AIM: This study investigates changes in therapy and long-term survival for patients with epithelial ovarian cancer (EOC) in the Netherlands. METHODS: All patients with EOC, including peritoneal and fallopian tube carcinoma, diagnosed in the Netherlands between 1989 and 2014 were selected from the Netherlands Cancer Registry. Changes in therapy were studied and related to overall survival (OS) using multivariable Cox regression models. RESULTS: A total of 32,540 patients were diagnosed with EOC of whom 22,047 (68%) had advanced stage disease. In early stage, lymph node dissection as part of surgical staging procedures increased over time from 4% in 1989-1993 to 62% in 2009-2014 (P < 0.001). In advanced stage, the number of patients receiving optimal treatment with surgery and chemotherapy increased from 55% in 1989-1993 to 67% in 2009-2014 (P < 0.001). Five-year survival rates improved in both early stage (74% versus 79%) and advanced stage (16% versus 24%) as well as in all patients combined (31% versus 34%). Ten-year survival rates, however, slightly improved in early stage (62% versus 67%) and advanced stage (10% versus 13%) but remained essentially unchanged at 24% for all patients combined. CONCLUSION: Despite intensified treatment and staging procedures, long-term survival for women with EOC has not improved in the last 25 years. The observed improvements in 5-year OS reflect a more prolonged disease control rather than better chances for cure. Furthermore, the apparent better long-term outcome, when early and advanced stage patients are analysed separately, is largely due to improved staging procedures and the ensuing stage migration. These effects disappear in a combined analysis of all patients. PMID- 29179133 TI - Improved heart repair upon myocardial infarction: Combination of magnetic nanoparticles and tailored magnets strongly increases engraftment of myocytes. AB - Cell replacement in the heart is considered a promising strategy for the treatment of post-infarct heart failure. Direct intramyocardial injection of cells proved to be the most effective application route, however, engraftment rates are very low (<5%) strongly hampering its efficacy. Herein we combine magnetic nanoparticle (MNP) loading of EGFP labeled embryonic cardiomyocytes (eCM) and embryonic stem cell-derived cardiomyocytes (ES-CM) with application of custom designed magnets to enhance their short and long-term engraftment. To optimize cellular MNP uptake and magnetic force within the infarct area, first numerical simulations and experiments were performed in vitro. All tested cell types could be loaded efficiently with SOMag5-MNP (200 pg/cell) without toxic side effects. Application of a 1.3 T magnet at 5 mm distance from the heart for 10 min enhanced engraftment of both eCM and ES-CM by approximately 7 fold at 2 weeks and 3.4 fold (eCM) at 8 weeks after treatment respectively and also strongly improved left ventricular function at all time points. As underlying mechanisms we found that application of the magnetic field prevented the initial dramatic loss of cells via the injection channel. In addition, grafted eCM displayed higher proliferation and lower apoptosis rates. Electron microscopy revealed better differentiation of engrafted eCM, formation of cell to cell contacts and more physiological matrix formation in magnet-treated grafts. These results were corroborated by gene expression data. Thus, combination of MNP loaded cells and magnet-application strongly increases long-term engraftment of cells addressing a major shortcoming of cardiomyoplasty. PMID- 29179134 TI - A randomised phase II study of chemoradiotherapy with or without nimotuzumab in locally advanced oesophageal cancer: NICE trial. AB - PURPOSE: Chemoradiotherapy is the standard treatment for patients with inoperable locally advanced oesophageal cancer. We sought to assess the safety and efficacy of chemoradiation combined with nimotuzumab, a humanised antibody directed against epidermal growth factor receptor (EGFR). PATIENTS AND METHODS: Untreated patients with inoperable locally advanced oesophageal cancer and no distant metastases were randomised to chemoradiotherapy (cisplatin and fluorouracil combined with external beam radiation) alone or in combination with nimotuzumab. The primary end-point was the endoscopic complete response (eCR) rate, and secondary end-points comprised quality of life (QoL) and safety. The combined eCR and pathologic complete response (cEPCR) and overall survival (OS) were also evaluated. RESULTS: We enrolled 107 patients with a mean age of 59 years, and 93% had squamous cell carcinoma. Toxicity was manageable in both arms with no important differences in adverse events (AEs). We performed post-treatment endoscopies in 67 patients, including 60 who had a biopsy. In the intent-to-treat population, the eCR rates with and without nimotuzumab were 47.2% and 33.3% (P = 0.17), respectively, and the cEPCR rates were 62.3% and 37.0% (P = 0.02), respectively. With a median follow-up of 14.7 months, the hazard ratio (HR) for OS was 0.68 (95% confidence interval (CI): 0.44-1.07; P = 0.09) with a median OS of 15.9 months for the nimotuzumab arm and 11.5 months for the control arm. Regarding QoL, a significant difference was observed for the physical subscale score (P = 0.03) with lower values for the control arm. CONCLUSION: Combined chemoradiotherapy plus nimotuzumab is safe for patients with locally advanced oesophageal cancer, it appears to increase the cEPCR rate, and without compromising QoL. CLINICAL TRIALS: Identification number: EF024-201; Trial registry: NCT01249352. PMID- 29179136 TI - Cross-cultural psychometric assessment of the VAGUS insight into psychosis scale Spanish version. AB - Impaired insight into illness, a core feature of schizophrenia with negative clinical implications, is a multidimensional phenomenon existing on a continuum. However, the degree to which illness perception in distinct cultures influences the appraisal of insight into illness in schizophrenia remains unclear. As such, we aimed to determine if the psychometric properties of the VAGUS insight into psychosis scale (www.vagusonline.com), which was originally assessed in English speaking Canadians, were similar in a sample of Latino Mexican Spanish speaking patients with schizophrenia. To accomplish this, the VAGUS - Self-Report (SR) version was translated from English to Spanish and psychometrically evaluated in 95 participants. The Spanish version of the VAGUS-SR was internally consistent (? = 0.713), and demonstrated good convergent and discriminant validity with the subscales of the Positive and Negative Syndrome Scale. Factor analysis identified two components of insight, congruent with two of the components of the English version of the VAGUS-SR. In conclusion, the VAGUS-SR is a brief, novel, and valid measure of insight into illness in schizophrenia, which demonstrated similar psychometric properties in two culturally and linguistically distinct samples with schizophrenia. Future studies should assess whether the VAGUS demonstrates similar psychometric properties in non-Western cultures. PMID- 29179137 TI - Group Metacognitive Therapy vs. Mindfulness Meditation Therapy in a Transdiagnostic Patient Sample: A Randomised Feasibility Trial. AB - Two transdiagnostic therapies for treating psychological disorder are Metacognitive Therapy (MCT) and Mindfulness Based Stress Reduction (MBSR). These two approaches have yet to be compared and therefore the current study aimed to evaluate the feasibility of a study of group MCT and MBSR in treating anxiety and depression. A feasibility trial with 40 participants (aged 19-56) was conducted. Patients were randomly assigned to receive either eight weeks of group MCT or MBSR. The primary outcome was feasibility which included recruitment rates, retention and treatment acceptability. The primary symptom outcome was the Hospital Anxiety and Depression Scale (HADS) total score, which provided an overall measure of distress. Both treatments were found to be acceptable with low attrition and similar ratings of acceptability. Changes in outcomes were analyzed based on the intention-to-treat principle using mixed effect models. Preliminary analyses revealed that MCT was more effective in treating anxiety and depression in comparison to MBSR, and in reducing both positive and negative metacognitive beliefs. Reliable improvement rates favoured MCT at post-treatment and 6-month follow up. Both treatments appeared to be feasible and acceptable in treating transdiagnostic samples; however, a larger, definitive trial is required. The limitations and directions for future research are discussed. PMID- 29179138 TI - Pathological jealousy and pathological love: Apples to apples or apples to oranges? AB - Pathological jealousy evokes emotions, thoughts, and behaviors that cause damage to social and interpersonal relationships. On the other hand, pathological love is the uncontrollable behavior of caring for a partner that results in neglecting the needs of the self. The aim of the present research was to assess the similarities and differences between the two psychopathologies of love. To this end, thirty-two individuals with pathological jealousy and 33 individuals with pathological love were compared on demographics, aspects of romantic relationship (jealousy, satisfaction, love style), psychiatric co-morbidities, personality and psychological characteristics (e.g., impulsivity). In a univariate analysis individuals with pathological jealousy were more likely to be in a current relationship and reported greater satisfaction. The avoidant attachment and the ludus love style were associated with pathological jealousy whereas the secure attachment and agape love style was associated with pathological love. Almost three-quarters (72.3%) of the sample met criteria for a current psychiatric disorder, however no differences emerged between the pathological jealousy and pathological love groups. In a binary logistic regression, relationship status and impairments in parenting significantly differentiated the groups. While both pathological jealousy and pathological love share similarities, they also present with unique differences, which may have important treatment implications. PMID- 29179139 TI - A comparison of two evisceration methods on hygienic quality in the pelvic area of sheep carcasses. AB - The aim was to compare the effects of two evisceration methods under operational conditions, on the pelvic hygiene of sheep carcasses. Method 1: rectum sealed with plastic bag and pushed through the pelvic cavity. Method 2: rectum cut, placed back inside and pulled out from the carcass. The 18 largest Norwegian sheep abattoirs participated. Sampling areas were i) 400cm2 inside the pelvic cavity (n=623), ii) 100cm2 outside the circum-anal incision (n=622). There were pooled samples by swabbing the same area of five carcasses, representing totally 3115 carcasses. Mean E. coli results from Method 1: -1.61logCFU/cm2 inside and 0.25logCFU/cm2 for the outside area. Results from Method 2: -1.56logCFU/cm2 inside and -0.42logCFU/cm2 outside. There were no significant differences between the two methods. Both evisceration methods can produce carcasses that are of practically identical high hygienic quality. PMID- 29179140 TI - Modifying a negative interpretation bias for ambiguous social scenarios that depict the risk of rejection in women with anorexia nervosa. AB - BACKGROUND: A heightened sensitivity to social rejection might contribute towards the interpersonal difficulties and symptoms that characterise Anorexia Nervosa (AN). This paper examines the effect of Cognitive Bias Modification for Interpretation biases (CBM-I) training on a negative interpretation bias for ambiguous social scenarios that involve the risk of rejection and eating behaviour. METHOD: Women with AN received a single session of CBM-I training to develop a more benign interpretational style or a control condition (which included 50:50 negative and benign resolutions). To measure participant's interpretation bias for social stimuli, a sentence completion task was used pre and post-training (a near-transfer outcome measure). A test meal was given after the training and salivary cortisol (stress) levels were measured as far-transfer outcome measures. RESULTS: CBM-I training led to a significant reduction in a negative interpretation bias in both conditions. No effect on eating behaviour or stress was found, which may be expected as the training conditions did not significantly differ in interpretation bias change. LIMITATIONS: The control condition may have inadvertently reduced a negative interpretation bias as it involved listening to benign resolutions to ambiguous social scenarios for 50% of the trials. CONCLUSIONS: It is possible to modify a negative interpretation bias for social stimuli. To clarify the effect of CBM-I training on AN symptomatology, repeated, more intensive, and ecologically-valid training interventions may be required. This is because any change in eating behaviour may not be immediate, particularly in a population with a low body mass index and long-illness durations. PMID- 29179141 TI - A study of the real-world effectiveness of group psychoeducation for bipolar disorders: Is change in illness perception a key mediator of benefit? AB - BACKGROUND: Findings from efficacy trials of group psychoeducation (PE) for bipolar disorders (BD) led to its inclusion in evidence-based guidelines as a first-line mandatory treatment. However, pragmatic trials and observational studies are needed to determine its real-world effectiveness, impact on outcomes deemed important to patients and to clarify potential mediators of any benefits. METHODS: Individuals with BD were offered the opportunity to participate in 20h of PE and asked to complete pre- and post-intervention ratings of symptoms, knowledge about BD, medication adherence, and illness perception. A priori, two key patient outcomes were identified (social functioning and self-esteem); sample attrition due to dropout or relapse was recorded. RESULTS: Of 156 individuals who completed the pre-PE assessments, 103 completed the program and post-PE assessments. Only 4 of 53 dropouts were associated with BD relapse. Post intervention, the PE completers demonstrated a statistically significant improvement in social functioning (p = 0.003, Effect Size (ES) = 0.26) and a trend towards improved self-esteem (ES = 0.14). Whilst there were significant changes in medication adherence (p = 0.002, ES = 0.28), knowledge of BD (p < 0.001, ES = 1.20), and illness perception (p < 0.001, ES = -0.37), mediational analysis demonstrated that only change in illness perception was associated to change in functioning (p=0.03) with no contribution from changes in knowledge of BD or medication adherence. CONCLUSIONS: In real-world settings, over 60% individuals completed 10-session course of PE. After controlling for demography and baseline clinical state, change in illness perception, rather than change in knowledge or medication adherence, emerged as a potential mediator of some benefits of PE. PMID- 29179142 TI - The relationship of person-specific eveningness chronotype, greater seasonality, and less rhythmicity to suicidal behavior: A literature review. AB - BACKGROUND: Epidemiological data have demonstrated seasonal and circadian patterns of suicidal deaths. Several reviews and meta-analyses have confirmed the relationship between sleep disturbance and suicidality. However, these reviews/meta-analyses have not focused on seasonal and circadian dysfunction in relation to suicidality, despite the common presence of this dysfunction in patients with mood disorders. Thus, the current literature review analyzed studies investigating person-specific chronotype, seasonality, and rhythmicity in relation to suicidal thoughts and behaviors. METHODS: Study authors reviewed articles related to individual-level chronotype, seasonality, and rhythmicity and suicidality that were written in English and not case reports or reviews. RESULTS: This review supports a relationship between an eveningness chronotype, greater seasonality, and decreased rhythmicity with suicidal thoughts and behaviors in those with unipolar depression, as well as in other psychiatric disorders and in children/adolescents. LIMITATIONS: These findings need to be explored more fully in mood disordered populations and other psychiatric populations, in both adults and children, with objective measurement such as actigraphy, and with chronotype, seasonality, and rhythmicity as well as broader sleep disturbance measurement all included so the construct(s) most strongly linked to suicidality can be best identified. CONCLUSIONS: Eveningness, greater seasonality, and less rhythmicity should be considered in individuals who may be at risk for suicidal thoughts and behaviors and may be helpful in further tailoring assessment and treatment to improve patient outcome. PMID- 29179144 TI - The centrality of DSM and non-DSM depressive symptoms in Han Chinese women with major depression. AB - INTRODUCTION: We compared DSM-IV criteria for major depression (MD) with clinically selected non-DSM criteria in their ability to represent clinical features of depression. METHOD: We conducted network analyses of 19 DSM and non DSM symptoms of MD assessed at personal interview in 5952 Han Chinese women meeting DSM-IV criteria for recurrent MD. We estimated an Ising model (the state of-the-art network model for binary data), compared the centrality (interconnectedness) of DSM-IV and non-DSM symptoms, and investigated the community structure (symptoms strongly clustered together). RESULTS: The DSM and non-DSM criteria were intermingled within the same symptom network. In both the DSM-IV and non-DSM criteria sets, some symptoms were central (highly interconnected) while others were more peripheral. The mean centrality of the DSM and non-DSM criteria sets did not significantly differ. In at least two cases, non-DSM criteria were more central than symptomatically related DSM criteria: lowered libido vs. sleep and appetite changes, and hopelessness versus worthlessness. The overall network had three sub-clusters reflecting neurovegetative/mood symptoms, cognitive changes and anxiety/irritability. LIMITATIONS: The sample were severely ill Han Chinese females limiting generalizability. CONCLUSIONS: Consistent with prior historical reviews, our results suggest that the DSM-IV criteria for MD reflect one possible sub-set of a larger pool of plausible depressive symptoms and signs. While the DSM criteria on average perform well, they are not unique and may not be optimal in their ability to describe the depressive syndrome. PMID- 29179143 TI - Factors associated with postpartum depression in women from low socioeconomic level in Argentina: A hierarchical model approach. AB - PURPOSE: to estimate the prevalence of depression at 4-week postpartum using the Edinburgh postpartum Depression Scale (EPDS) in women who delivered in a public maternity hospital in Argentina. METHODS: This prospective cohort study was carried out from March to August 2016 in northwest Argentina. Eligibility included delivering a singleton live birth 28 weeks of gestational age or over, 18 years or older and resided within 1h from the maternity hospital. Women were excluded if they or their newborn were in the intensive care unit. We defined a positive screening as an EPDS score of 10 or higher or a positive response to item 10, which indicates thoughts of self-harm. RESULTS: A total of 587 women were enrolled and 539 women completed the home visit interview and the EPDS. A total of 167 (31.0%, 95% CI 27.1-35.1) mothers screened positive in the EPDS using a score >= 10 and 99 (18.4%, 95% CI 15.1-21.6%) using a score >= 13, which indicate increased severity of depressive symptoms. In both cases, the 23 (4.3%) women that responded as having thoughts of self-harm were included. CONCLUSION: Nearly a third of women who participated had depressive symptoms at four weeks postpartum in a public hospital in Tucuman, Argentina. Socio-demographic, particularly personal psychiatric history, factors and social and cultural influences can impact results. Our results highlight the need for improved screening and better diagnostic tool for women with postpartum depression in Argentina and to investigate the impact of postpartum depressive symptoms on women's health and their families.

AB - This study investigated the treatment performance of three types of modified activated sludge processes, i.e., anoxic/oxic (A/O), anaerobic/anoxic/oxic (A2/O) and oxidation ditch process, in treating municipal wastewater by measuring physicochemical and spectroscopic parameters, and the toxicity of the influents and effluents collected from 8 full-scale municipal wastewater treatment plants (MWTPs). The relationships between spectroscopic and physicochemical parameters of the wastewater samples and the applicability of the nematode Caenorhabditis elegans (C. elegans) bioassays for the assessment of the toxic properties of municipal wastewater were also evaluated. The results indicated that the investigated MWTPs employing any of A/O, A2/O and oxidation ditch processes could effectively control the discharge of major wastewater pollutants including biochemical oxygen demand (BOD), chemical oxygen demand, nitrogen and phosphorus. The oxidation ditch process appeared to have the advantage of removing tyrosine like substances and presented slightly better removal efficiency of tryptophan like fluorescent (peak T) substances than the A/O and A2/O processes. Both ultraviolet absorbance at 254nm and peak T may be used to characterize the organic load of municipal wastewater, and peak T can be adopted as a gauge of the BOD removal efficacy of municipal wastewater treatment. Using C. elegans-based oxygen consumption rate assay for monitoring municipal wastewater toxicity deserves further investigations.

AB - Arsenic (As) and copper (Cu) are co-contaminants in the environment but little is known about their ecological impact as mixtures in soil. In this study, we investigated the combined As-Cu interactions on toxicity and uptake as binary mixtures in 5 contrasting soils. The study included solubility, contaminant uptake and toxicity in cucumber (Cucumis sativus L.) as a model plant species. Soils were spiked individually and as a mixtures at 10 different As levels (2, 4, 8 up to 1024mgkg-1). Copper was added with As at two effective concentration levels (EC10Cu and EC50Cu). Arsenic uptake was significantly reduced in the presence of Cu and a higher effect was demonstrated with increasing pore-water pH. Copper accumulation was not significantly influenced by As. An additive response on plant growth was predominant overall when expressed from pore-water parameters with root mean square errors of 12.6 and 13.2 for EC10Cu and EC50Cu treatments, respectively. PMID- 29179147 TI - Digital gene expression analysis in the gills of Ruditapes philippinarum exposed to short- and long-term exposures of ammonia nitrogen. AB - Previous study revealed severe toxic effects of ammonia nitrogen on Ruditapes philippinarum including lysosomal instability, disturbed metabolic profiles, gill tissues with damaged structure, and variation of neurotransmitter concentrations. However, the underlying molecular mechanism was not fully understood yet. In the present study, digital gene expression technology (DGE) was applied to globally screen the key genes and pathways involved in the responses to short- and long term exposures of ammonia nitrogen. Results of DGE analysis indicated that short term duration of ammonia exposure affected pathways in Dorso-ventral axis formation, Notch signaling, thyroid hormone signaling and protein processing in endoplasmic reticulum. The long-term exposure led to DEGs significantly enriched in gap junction, immunity, signal and hormone transduction, as well as key substance metabolism pathways. Functional research of significantly changed DEGs suggested that the immunity of R. philippinarum was weakened heavily by toxic effects of ammonia nitrogen, as well as neuro-transduction and metabolism of important substances. Taken together, the present study provides a molecular support for the previous results of the detrimental toxicity of ammonia exposure in R. philippinarum, further work will be performed to investigate the specific genes and their certain functions involved in ammonia toxicity to molluscs. PMID- 29179148 TI - Systemic response of the stony coral Pocillopora damicornis against acute cadmium stress. AB - Heavy metals have become one of the main pollutants in the marine environment and a major threat to the growth and reproduction of stony corals. In the present study, the density of symbiotic zooxanthellae, levels of crucial physiological activities and the transcriptome were investigated in the stony coral Pocillopora damicornis after the acute exposure to elevated cadmium concentration. The density of symbiotic zooxanthellae decreased significantly during 12-24h period, and reached lowest at 24h after acute cadmium stress. No significant changes were observed in the activity of glutathione S-transferase during the entire stress exposure. The activities of superoxide dismutase and catalase, and the concentration of glutathione decreased significantly, but the activation level of caspase3 increased significantly after cadmium exposure. Furthermore, transcriptome sequencing and bioinformatics analysis revealed 3538 significantly upregulated genes and 8048 significantly downregulated genes at 12h after the treatment. There were 12 overrepresented GO terms for significantly upregulated genes, mostly related to unfolded protein response, endoplasmic reticulum stress and apoptosis. In addition, a total of 32 GO terms were overrepresented for significantly downregulated genes, and mainly correlated with macromolecular metabolic processes. These results collectively suggest that acute cadmium stress could induce apoptosis by repressing the production of the antioxidants, elevating oxidative stress and activating the unfolded protein response. This cascade of reactions would result to the collapse of the coral-zooxanthella symbiosis and the expulsion of symbiotic zooxanthellae in the stony coral P. damicornis, ultimately leading to coral bleaching. PMID- 29179149 TI - Differential response between histological and biochemical biomarkers in the apple snail Pomacea canaliculata (Gasteropoda: Amullariidae) exposed to cypermethrin. AB - To develop effective programs to monitor water quality is necessary to identify sensitive biomarkers in indicator species. The aim of this study was to evaluate different biomarkers in the apple snail Pomacea canaliculata exposed to the insecticide Cypermethrin (CYP). Adult male and female snails were exposed to sublethal CYP concentrations (10, 25 and 100MUgl-1) for 1, 4, 7 and 14days. The recovery of the exposed snails was also studied by a post-exposure assay. The activities of the enzymes superoxide dismutase (SOD), catalase (CAT) and glutathione-S-transferase (GST), the levels of lipid peroxidation (LPO) and protein oxidation (PC) in digestive gland and gills were studied as biomarkers of exposure. Histopathological changes in target tissues were also evaluated. In digestive gland, CYP caused a significant increase in SOD, CAT and GST activities compared to control (p<0.05) as well as in LPO and PC levels (p<0.05). However, such biochemical effects were neither concentration nor time dependent. Histopatological changes were observed in the exposed groups, such as an increase in the number of basophilic cells, hemocytic infiltration and epithelia atrophy. Additionally, a positive correlation between the surface occupied by pigmented corpuscles and CYP concentrations was observed at all exposure periods. Gills showed greater sensitivity to oxidative damage than digestive gland. CYP caused an acute toxic effect in LPO levels in this respiratory organ. The gill filament of exposed snails, exhibited a reduction or loss of cilia, vacuolization of the columnar cells and an increase in haemocyte content irrespective of the concentration. High concentrations of CYP caused disruptions in the columnar muscle fibers. In general, snails did not show an improvement in their basal state during post-exposure treatment. Apparently, males and females do not have differential sensitivity to the pesticide. The results of this study suggest that histopathological changes are the most sensitive time- and dose-dependent biomarkers of toxicity induced by CYP in P. canaliculata. PMID- 29179151 TI - Photomixotrophic chemical production in cyanobacteria. AB - The current global dependence on fossil fuels for both energy and chemical production has spurred concerns regarding long-term resource security and environmental detriments resulting from increased CO2 levels. Through the installation of exogenous metabolic pathways, engineered cyanobacteria strains can directly fix CO2 into industrially relevant chemicals currently produced from petroleum. This review highlights some of the studies that have successfully implemented photomixotrophic conditions to increase cyanobacterial chemical production. Supplementation with fixed carbon sources provides additional carbon building blocks and energy to enhance production and occasionally aid in growth. Photomixotrophic production has increased titers up to 5-fold over traditional autotrophic conditions, demonstrating promising applications for future commercialization. PMID- 29179150 TI - Effect of imidacloprid on the survival of Xenopus tadpoles challenged with wild type frog virus 3. AB - The sensitivity of amphibians to Ranavirus may be increased by exposure to other environmental stressors, including chemical contaminants. Neonicotinoid insecticides comprise 27% of the global insecticide market and have been detected in wetlands and other aquatic habitats. The present study focused on the effects of exposure of pre-metamorphic Xenopus laevis to the neonicotinoid, imidacloprid (IMI) on sensitivity to frog virus 3 (FV3) infection. It was hypothesized that exposure of tadpoles to IMI at sublethal concentrations of 1 and 500MUgL-1 would increase FV3 related mortalities relative to tadpole mortalities in a control treatment with only the virus. However, contrary to the predicted outcome, IMI reduced the rates of mortality following viral challenge, although the total mortalities by the 25th day after infection did not differ among the treatments. These results should not be interpreted as an indication that neonicotinoid insecticides are beneficial to aquatic ecosystems, since these insecticides cause toxic responses at low concentrations to other non-target aquatic organisms.

AB - Memristor is firstly postulated by Leon Chua and realized by Hewlett-Packard (HP) laboratory. Research results show that memristor can be used to simulate the synapses of neurons. This paper presents a class of recurrent neural network with HP memristors. Firstly, it shows that memristive recurrent neural network has more compound dynamics than the traditional recurrent neural network by simulations. Then it derives that n dimensional memristive recurrent neural network is composed of [Formula: see text] sub neural networks which do not have a common equilibrium point. By designing the tracking controller, it can make memristive neural network being convergent to the desired sub neural network. At last, two numerical examples are given to verify the validity of our result. PMID- 29179153 TI - Reduced-order state estimation of delayed recurrent neural networks. AB - Different from the widely-studied full-order state estimator design, this paper focuses on dealing with the reduced-order state estimation problem for delayed recurrent neural networks. By employing an integral inequality, a delay-dependent design approach is proposed, and global asymptotical stability of the resulting error system is guaranteed. It is shown that the gain matrix of the reduced-order state estimator is determined by the solution of a linear matrix inequality. Numerical examples are provided to illustrate the effectiveness of the developed result. PMID- 29179154 TI - Understanding sexual assault risk perception in college: Associations among sexual assault history, drinking to cope, and alcohol use. AB - INTRODUCTION: Sexual assault history and alcohol use are associated with higher likelihood of subsequent sexual assault. Alcohol use and drinking to cope are associated with re-assault, but it is unclear whether these factors are associated with malleable constructs like sexual assault risk perception. This study examined typical weekly drinking and drinking to cope motive as factors underlying the association between sexual assault history and risk perception. METHODS: Both perceived likelihood of experiencing incapacitated sexual assault and when to leaving a hypothetical sexual assault scenario were assessed as indicators of sexual assault risk perception. 660 female college students recruited from psychology courses completed questionnaires online. RESULTS: Results revealed that sexual assault history severity was positively associated with perceived incapacitated sexual assault likelihood and when to leave a risky scenario. Drinking to cope with anxiety was positively associated with perceived incapacitated sexual assault likelihood. Among women who reported regular drinking, typical weekly drinking was positively associated with when to leave a risky scenario, such that women who reported more weekly drinks stayed in a potentially risky scenario longer than women who reported fewer weekly drinks. CONCLUSIONS: These findings suggest that alcohol use and drinking to cope with anxiety are associated with risk perception. Sexual assault history was associated with both perceived incapacitated sexual assault likelihood and when to leave a hypothetical scenario. Alcohol use and drinking to cope are two potential points of intervention for sexual assault risk reduction programs, but further examination is needed. PMID- 29179155 TI - Patterns of adverse childhood experiences and substance use among young adults: A latent class analysis. AB - INTRODUCTION: Adverse childhood experiences (ACEs) have been strongly linked with subsequent substance use. The aim of this study was to investigate how different patterns of ACEs influence substance use in young adulthood. METHODS: Using a community sample of young individuals (N=336; ages 18-25), we performed latent class analyses (LCA) to identify homogenous groups of young people with similar patterns of ACEs. Exposure to ACEs incorporates 13 childhood adversities including childhood maltreatment, household dysfunction, and community violence. Multiple linear and logistic regression models were used in an effort to examine the associations between ACEs classes and four young adult outcomes such as alcohol-related problems, current tobacco use, drug dependence symptoms, and psychological distress. RESULTS: LCA identified four heterogeneous classes of young people distinguished by different patterns of ACEs exposure: Low ACEs (56%), Household Dysfunction/Community Violence (14%), Emotional ACEs (14%), and High/Multiple ACEs (16%). Multiple regression analyses found that compared to those in the Low ACEs class, young adults in the High/Multiple ACEs class reported more alcohol-related problems, current tobacco use, and psychological symptoms, controlling for sociodemographic characteristics and common risk factors for substance use such as peer substance use. CONCLUSIONS: Our findings confirm that for many young people, ACEs occur as multiple rather than single experiences. The results of this research suggest that exposure to poly victimization during childhood is particularly related to substance use during young adulthood. PMID- 29179157 TI - Measurement of the bone endocortical region using clinical CT. AB - The extent of the endocortical region and cortical bone mineral density (cBMD) throughout the proximal femur are of interest as both have been linked to fracture risk and osteoporosis treatment response. Non-invasive in-vivo clinical CT-based techniques capable of measuring the cortical bone attributes of thickness, density and mass over a bone surface have already been proposed. Several studies have robustly shown these methods to be capable of producing cortical thickness measurements to a sub-millimetre accuracy. Unfortunately, these methods are unable to provide high quality cBMD estimates, and are not designed to measure any attributes over the endocortical region of cortical bone. In this paper, we develop a cortical bone mapping based technique capable of providing an improved cBMD estimate and a measure of the endocortical width, while maintaining similar quality cortical thickness and trabecular bone mineral density (tBMD) estimates. The performance of the technique was assessed using a paired dataset of ex-vivo QCT and HR-pQCT scans across 72 proximal femurs. The HR pQCT scans were analysed using a new method developed for this study: high resolution tissue classification (HRTC). In HRTC the cortical, endocortical and sub-surface trabecular bone features are extracted from the partially resolvable microarchitectural details in the HR-pQCT scan. We demonstrate that measurement of the endocortical extent from QCT is possible with an accuracy of -0.15+/ 0.71mm, and that local cBMD can be measured down to densities of 300 mg/cm3. PMID- 29179158 TI - Modelling nonlinearity of guided ultrasonic waves in fatigued materials using a nonlinear local interaction simulation approach and a spring model. AB - Modelling and numerical simulation - based on the framework of the Local Interaction Simulation Approach - was developed to have more insight into nonlinear attributes of guided ultrasonic waves propagating in fatigued metallic materials. Various sources of nonlinearity were considered in this modelling work, with particular emphases on higher-order harmonic generation and accumulation of nonlinearity along wave propagation. The material hyper elasticity was considered in the model using an energy density approach based on the Landau-Lifshitz formulation; and the "breathing" motion pattern of a fatigue crack in the material was interrogated using a spring model. Upon the successful validation with the model prepared in the commercial software based on the Finite Element Methods, two scenarios were comparatively investigated, i.e. the lower and higher frequency regime. In the first case propagation of a basic symmetric mode pair was simulated using the model to observe a cumulative characteristic of the second harmonic mode with nonlinear hyper-elastic material definition upon appropriate selection of excitation frequency. In the second case, the higher order symmetric mode pair was excited according to the "internal resonance" conditions, revealing a strong dependence of manifested nonlinearity on numerical parameters. Moreover, it was shown that with the use of the wave from the low frequency regime it was easier to differentiate later stages of the crack development, being in contrary to waves in the high frequency regime, which allowed to clearly observe early stages of the crack expansion. Such outcome lays the foundation to develop the damage detection and monitoring scheme in the field of Structural Health Monitoring based on utilising the nonlinear features of guided ultrasonic waves. PMID- 29179156 TI - Radiosensitization with an inhibitor of poly(ADP-ribose) glycohydrolase: A comparison with the PARP1/2/3 inhibitor olaparib. AB - Upon DNA binding the poly(ADP-ribose) polymerase family of enzymes (PARPs) add multiple ADP-ribose subunits to themselves and other acceptor proteins. Inhibitors of PARPs have become an exciting and real prospect for monotherapy and as sensitizers to ionising radiation (IR). The action of PARPs are reversed by poly(ADP-ribose) glycohydrolase (PARG). Until recently studies of PARG have been limited by the lack of an inhibitor. Here, a first in class, specific, and cell permeable PARG inhibitor, PDD00017273, is shown to radiosensitize. Further, PDD00017273 is compared with the PARP1/2/3 inhibitor olaparib. Both olaparib and PDD00017273 altered the repair of IR-induced DNA damage, resulting in delayed resolution of RAD51 foci compared with control cells. However, only PARG inhibition induced a rapid increase in IR-induced activation of PRKDC (DNA-PK) and perturbed mitotic progression. This suggests that PARG has additional functions in the cell compared with inhibition of PARP1/2/3, likely via reversal of tankyrase activity and/or that inhibiting the removal of poly(ADP-ribose) (PAR) has a different consequence to inhibiting PAR addition. Overall, our data are consistent with previous genetic findings, reveal new insights into the function of PAR metabolism following IR and demonstrate for the first time the therapeutic potential of PARG inhibitors as radiosensitizing agents. PMID- 29179159 TI - CNTNAP2 mutations and autosomal dominant epilepsy with auditory features. AB - Autosomal dominant epilepsy with auditory features (ADEAF) is clinically characterized by focal seizures with prominent auditory or aphasic auras and absence of structural brain abnormalities. Mutations in LGI1 and RELN genes account for the disorder in about 50% of ADEAF families. In a recent paper, a heterozygous intragenic deletion in the CNTNAP2 gene has been associated to ADEAF in a single family. We screened 28 ADEAF families for mutations in CNTNAP2 by next generation sequencing and copy number variation analyses and found no likely pathogenic mutations segregating with the disease. CNTNAP2 should be screened in genetically unsolved ADEAF families, but causative mutations are expected to be infrequent in this gene. PMID- 29179160 TI - Estimation of different source contributions to sediment organic matter in an agricultural-forested watershed using end member mixing analyses based on stable isotope ratios and fluorescence spectroscopy. AB - The two popular source tracing tools of stable isotope ratios (delta13C and delta15N) and fluorescence spectroscopy were used to estimate the relative source contributions to sediment organic matter (SeOM) at five different river sites in an agricultural-forested watershed (Soyang Lake watershed), and their capabilities for the source assignment were compared. Bulk sediments were used for the stable isotopes, while alkaline extractable organic matter (AEOM) from sediments was used to obtain fluorescent indices for SeOM. Several source discrimination indices were fully compiled for a range of the SeOM sources distributed in the catchments of the watershed, which included soils, forest leaves, crop (C3 and C4) and riparian plants, periphyton, and organic fertilizers. The relative source contributions to the river sediment samples were estimated via end member mixing analysis (EMMA) based on several selected discrimination indices. The EMMA based on the isotopes demonstrated that all sediments were characterized by a medium to a high contribution of periphyton ranging from ~30% to 70% except for one site heavily affected by forest and agricultural fields with relatively high contributions of terrestrial materials. The EMMA based on fluorescence parameters, however, did not show similar results with low contributions from forest leaf and periphyton. The characteristics of the studied watershed were more consistent with the source contributions determined by the isotope ratios. The discrepancy in the EMMA capability for source assignments between the two analytical tools can be explained by the limited analytical window of fluorescence spectroscopy for non-fluorescent dissolved organic matter (FDOM) and the inability of AEOM to represent original bulk particulate organic matter (POM).

Bone remodeling demonstrates sequential phase of activation, resorption, reversal, and formation. Bone histomorphometry can make the quantitative assessment of the turnover in bone remodeling. PMID- 29179162 TI - [The role of osteoclastic bone resorption on bone remodeling.] AB - Bone remodeling consists of bone resorbing cycle and bone forming cycle to maintain bone volume and calcium homeostasis thought life. The main cells involves in bone remodeling are osteoclasts and osteoblasts. Bone resorption and bone formation are tightly coupled during bone remodeling, an imbalance of these two processes leads to either increased or decreased bone mass. Osteoclasts are multinucleated cells responsible for physiological and pathological bone resorption and thereby play an essential role in maintaining bone volume and homeostasis. Osteoclastic bone resorption is regulated by several cytokines, calcium signal, and transcription factors etc. Recent molecular dissection of genetic disorders of high increased or decreased bone mass has proven many of the crucial molecules controlling the osteoclastic bone resorption. This article reviews recent findings of molecular mechanism regarding to osteoclastic bone resorption to regulate bone remodeling. PMID- 29179163 TI - [The role of osteocytes in bone remodeling.] AB - Bone remodeling has important roles in the functions of bone tissues, such as supporting the body and mineral storage. Osteocytes, which are the most abundant cells in bone tissues, detect the mechanical loading and regulate both bone formation by osteoblasts and bone resorption by osteoclasts. However, its mechanism is still unknown. In this review, we summarize how osteocytes detect mechanical stress and discuss the potential role of CCN2/CTGF as a novel bone remodeling factor produced by osteocytes. PMID- 29179164 TI - [Coupling of bone resorption and formation.] AB - Preceding bone resorption is a prerequisite for the initiation of subsequent bone formation during adulthood and the quantity as well as the quality of bone is maintained by which newly formed bone by osteoblasts replaces precisely the amount removed by osteoclastic bone resorption at the same level. This process is namely " bone remodeling " and the rely of bone formation in response to resorption is termed " coupling " . Importantly, bone formation is induced by osteoclastic bone resorption or the presence of osteoclasts themselves in the bone remodeling. Recently, emerging evidence points to the involvement of factors secreted or presented by osteoclasts themselves in the coupling process. Thus, coupling mechanisms involved in the bone remodeling are critical for understanding of bone physiology and metabolic bone diseases such as osteoporosis. PMID- 29179165 TI - [Bone remodeling and modeling/mini-modeling.] AB - Modeling, adapting structures to loading by changing bone size and shapes, often takes place in bone of the fetal and developmental stages, while bone remodeling replacement of old bone into new bone-is predominant in the adult stage. Modeling can be divided into macro-modeling(macroscopic modeling)and mini modeling(microscopic modeling). In the cellular process of mini-modeling, unlike bone remodeling, bone lining cells, i.e., resting flattened osteoblasts covering bone surfaces will become active form of osteoblasts, and then, deposit new bone onto the old bone without mediating osteoclastic bone resorption. Among the drugs for osteoporotic treatment, eldecalcitol(a vitamin D3 analog)and teriparatide(human PTH[1-34])could show mini-modeling based bone formation. Histologically, mature, active form of osteoblasts are localized on the new bone induced by mini-modeling, however, only a few cell layer of preosteoblasts are formed over the newly-formed bone, and accordingly, few osteoclasts are present in the region of mini-modeling. In this review, histological characteristics of bone remodeling and modeling including mini-modeling will be introduced. PMID- 29179166 TI - [Immobilization and bone remodeling disorder.] AB - Mechanical stress is essential for us to maintain bone volume and structure. Immobilization and unloading, such as motor paralysis, long-term bedrest and casting of fractured area, cause rapidly remarkable bone loss. The bone remodeling disorder following immobilization demonstrates the acceleration of bone resorption and the suppression of bone formation, and molecular mechanism of the bone remodeling disorder has been gradually revealed recently. It is very difficult for us to improve the bone loss due to disuse completely. Thus, prevention of disuse osteoporosis is important. We should choose suitable treatment after considering the pathophysiology of disuse osteoporosis, and attempt early intervention as soon as possible. PMID- 29179167 TI - [Glucocorticoid-induced abnormality in bone remodeling.] AB - Glucocorticoid(GC)is widely used to treat a variety of autoimmune, inflammatory and allergic diseases. GC causes a number of adverse effects and among them osteoporosis and degenerative bone fracture are major complications of GC therapy. GC inhibits differentiation of mesenchymal stem cells to osteoblasts, induces apoptosis of osteoblasts and osteocytes and prolongs lifespan of osteoclast, resulting in low bone mass and micro-architectural deterioration of bone tissue, which leads to severe osteoporosis, increased bone fragility and susceptibility to bone fracture. Physicians who prescribe GC have to manage patients according to guidelines on the management and treatment of GC-induced osteoporosis. PMID- 29179168 TI - [The impact of controlling bone remodeling in rheumatoid arthritis.] AB - Rheumatoid arthritis(RA)is associated with increased bone turnover and early bone loss, which lead to increased fracture risk and progressive joint destruction. Pro-inflammatory cytokines, such as IL(interleukin)-17, TNF-alpha(tumor necrosis factor alpha), IL-1, and IL-6 induce the expression of RANKL(receptor activation of nuclear factor kappaB ligand)from synovial fibroblasts. RANKL promotes osteoclasts differentiation and activation, and Denosumab, an anti-RANKL monoclonal antibody, inhibits both systemic bone loss and focal bone erosion of RA. PMID- 29179169 TI - [Bone remodeling through a phosphate metabolism.] AB - Phosphorus is the second abundant mineral stored in bones, and disturbance of phosphate metabolisms results in various disease developments such as hypophosphatemic rickets. Blood phosphorus levels are regulated by dietary intake or its absorption from intestine, proximal tubular reabsorption, and number of factors plays roles for maintaining phosphate homeostasis. Vitamin D stimulates intestinal phosphorus absorption, and phosphorus promotes FGF23 secretion from osteocytes. FGF23 inhibits Cyp27b1, an enzyme to produce an active vitamin D3, 1,25(OH)2D3, through FGF receptor/Klotho complex. In this review, I will discuss about the roles of Enpp1 in regulating the FGF23-Klotho-vitamin D axis and bones.

The functional interaction between skeletal and hematopoietic systems has been revealed recently. The roles of osteoblasts as a component of hematopoietic microenvironment have been intensively studied, which is now an important research field. On the other hand, the functions of hematopoietic cells as regulators of osteoblasts have also been elucidated gradually. This review describes how innate immune cells such as macrophages and neutrophils take part in bone metabolism. PMID- 29179171 TI - [Aberrant bone remodeling during sepsis.] AB - Sepsis is a systemic inflammatory response syndrome that occurs upon severe bacterial infection. Although the development of early treatment for sepsis improves the survival rate of sepsis patients, in the subacute phase, certain patients suffer from secondary infection due to immunosuppression. It has been reported that one of the causes of the immunocompromised state during sepsis is lymphopenia. However, the underlying mechanisms are not well understood. We found that acute inflammation induced the immunodeficiency caused by the reduction of the numbers of peripheral lymphocytes and common lymphoid progenitors(CLPs)in the bone marrow, which was associated with a dramatic decrease in the osteoblast number. Osteoblast-specific deletion of IL-7 provided evidence for the role of osteoblasts in the regulation of lymphopoiesis in systemic inflammation. An acute loss of osteoblasts in sepsis induced the disturbance of lymphocyte homeostasis, resulting in immunodeficiency. PMID- 29179172 TI - [Control of bone remodeling by bone anabolic drugs.] AB - Teriparatide is a bone anabolic drug that is only available in practice. It is a N-terminal fragment of parathyroid hormone(PTH). Mode of actions of teriparatide is pharmacological but not physiological as it is administered to patients with osteoporosis. Physicians need to understand the fact that treatment with teriparatide is not just like a hormone replacement but its effects on bone remodeling are pharmacological. Romosozumab, under clinical development as anti osteoporosis drug, is a monoclonal antibody against sclerostin. Clinical data demonstrate that it temporally, but robustly activates bone formation as well as inhibits bone resorption. Thus, romosozumab is expected to have a strong anabolic action on bone remodeling. PMID- 29179173 TI - [Regulation of bone remodeling by anti-resorptives.] AB - Classical anti-resorptives such as bisphosphonates inhibit remodeling, leading to decreases in both bone resorption and formation markers. Changes in these markers are useful in predicting future bone mineral density and fracture risk to some extent. More recently developed drugs such as denosumab and odanacatib, which also fall into the category of anti-resorptives, show unique effects on modeling and remodeling. This overview summarizes action of anti-resorptives from a viewpoint of remodeling.

In addition, novel approaches such as drug development using genome-wide CRISPR screening and cancer suppression using epigenome editing technology, which can change the epigenetic modifications in a site-specific manner, have also been conducted. In this article, I summarize the current advances and future prospects of genome editing technology in the field of biomedicine. PMID- 29179175 TI - Novel Functional Role of Heat Shock Protein 90 in Mitochondrial Connexin 43 Mediated Hypoxic Postconditioning. AB - BACKGROUND/AIMS: Previous studies have shown that heat shock protein 90 (HSP90) mediated mitochondrial import of connexin 43 (Cx43) is critical in preconditioning cardioprotection. The present study was designed to test whether postconditioning has the same effect as preconditioning in promoting Cx43 translocation to mitochondria and whether mitochondrial HSP90 modulates this effect. METHODS: Cellular models of hypoxic postconditioning (HPC) from rat heart derived H9c2 cells and neonatal rat cardiomyocytes were employed. The effects of HPC on cardiomyocytes apoptosis were examined by flow cytometry and Hoechst 33342 fluorescent staining. Reactive oxidative species (ROS) production was assessed with the peroxide-sensitive fluorescent probe 2',7'-dichlorofluorescin in diacetate (DCFH-DA). The anti- and pro-apoptotic markers Bcl-2 and Bax, HSP90 and Cx43 protein levels were studied by Western blot analysis in total cell homogenate and sarcolemmal and mitochondrial fractions. The effects on HPC of the HSP90 inhibitor geldanamycin (GA), ROS scavengers superoxide dismutase (SOD) and catalase (CAT), and small interfering RNA (siRNA) targeting Cx43 and HSP90 were also investigated. RESULTS: HPC significantly reduced hypoxia/reoxygenation (H/R) induced cardiomyocyte apoptosis. These beneficial effects were accompanied by an increase in Bcl-2 levels and a decrease in Bax levels in both sarcolemmal and mitochondrial fractions. HPC with siRNA targeting Cx43 or the ROS scavengers SOD plus CAT significantly prevented ROS generation and HPC cardioprotection, but HPC with either SOD or CAT did not. These data strongly supported the involvement of Cx43 in HPC cardioprotection, likely via modulation of the ROS balance which plays a central role in HPC protection. Furthermore, HPC increased total and mitochondrial levels of HSP90 and the mitochondria-to-sarcolemma ratio of Cx43; blocking the function of HSP90 with the HSP90 inhibitor geldanamycin (GA) or siRNA targeting HSP90 prevented the protection of HPC and the HPC-induced association of Cx43, indicating that mitochondrial HSP90 was important for mitochondrial translocation of Cx43 during HPC. CONCLUSION: Mitochondrial HSP90 played a central role in HPC cardioprotection, and its activity was linked to the mitochondrial targeting of Cx43, the activation of which triggered ROS signaling and the subsequent reduction of redox stress. Consequently, its target gene, Bcl 2, was upregulated, and proapoptotic Bax was inhibited in the sarcolemma and mitochondria, ultimately attenuating H/R-induced cardiomyocyte apoptosis. These data reveal a novel mechanism of HPC protection. PMID- 29179176 TI - Neurons, Erythrocytes and Beyond -The Diverse Functions of Chorein. AB - Chorea-acanthocytosis (ChAc), a neurodegenerative disease, results from loss-of function-mutations of the chorein-encoding gene VPS13A. Affected patients suffer from a progressive movement disorder including chorea, parkinsonism, dystonia, tongue protrusion, dysarthria, dysphagia, tongue and lip biting, gait impairment, progressive distal muscle wasting, weakness, epileptic seizures, cognitive impairment, and behavioral changes. Those pathologies may be paralleled by erythrocyte acanthocytosis. Chorein supports activation of phosphoinositide-3 kinase (PI3K)-p85-subunit with subsequent up-regulation of ras-related C3 botulinum toxin substrate 1 (Rac1) activity, p21 protein-activated kinase 1 (PAK1) phosphorylation, and activation of several tyrosine kinases. Chorein sensitive PI3K signaling further leads to stimulation of the serum and glucocorticoid inducible kinase SGK1, which in turn upregulates ORAI1, a Ca2+ channel accomplishing store operated Ca2+-entry (SOCE). The signaling participates in the regulation of cytoskeletal architecture on the one side and cell survival on the other. Compromised cytoskeletal architecture has been shown in chorein deficient erythrocytes, fibroblasts and endothelial cells. Impaired degranulation was observed in chorein deficient PC12 cells and in platelets from ChAc patients. Similarly, decreased ORAI1 expression and SOCE as well as compromised cell survival were seen in fibroblasts and neurons isolated from ChAc patients. ORAI1 expression, SOCE and cell survival can be restored by lithium treatment, an effect disrupted by pharmacological inhibition of SGK1 or ORAI1. Chorein, SGK1, ORAI1 and SOCE further confer survival of tumor cells. In conclusion, much has been learned about the function of chorein and the molecular pathophysiology of chorea-acanthocytosis. Most importantly, a treatment halting or delaying the clinical course of this devastating disease may become available. A controlled clinical study is warranted, in order to explore whether the in vitro observations indeed reflect the in vivo pathology of the disease. PMID- 29179177 TI - Permanently Hypoxic Cell Culture Yields Rat Bone Marrow Mesenchymal Cells with Higher Therapeutic Potential in the Treatment of Chronic Myocardial Infarction. AB - BACKGROUND: The mismatch between traditional in vitro cell culture conditions and targeted chronic hypoxic myocardial tissue could potentially hamper the therapeutic effects of implanted bone marrow mesenchymal stem cells (BMSCs). This study sought to address (i) the extent of change to BMSC biological characteristics in different in vitro culture conditions and (ii) the effectiveness of permanent hypoxic culture for cell therapy in treating chronic myocardial infarction (MI) in rats. METHODS: rat BMSCs were harvested and cultured in normoxic (21% O2, n=27) or hypoxic conditions (5% O2, n=27) until Passage 4 (P4). Cell growth tests, flow cytometry, and Bio-Plex assays were conducted to explore variations in the cell proliferation, phenotype, and cytokine expression, respectively. In the in vivo set-up, P3-BMSCs cultured in normoxia (n=6) or hypoxia (n=6) were intramyocardially injected into rat hearts that had previously experienced 1-month-old MI. The impact of cell therapy on cardiac segmental viability and hemodynamic performance was assessed 1 month later by 2-Deoxy-2[18F]fluoro-D-glucose (18F-FDG) positron emission tomography (PET) imaging and pressure-volume catheter, respectively. Additional histomorphological examinations were conducted to evaluate inflammation, fibrosis, and neovascularization. RESULTS: Hypoxic preconditioning significantly enhanced rat BMSC clonogenic potential and proliferation without altering the multipotency. Different profiles of inflammatory, fibrotic, and angiogenic cytokine secretion were also documented, with a marked correlation observed between in vitro and in vivo proangiogenic cytokine expression and tissue neovessels. Hypoxic-preconditioned cells presented a beneficial effect on the myocardial viability of infarct segments and intrinsic contractility. CONCLUSION: Hypoxic-preconditioned BMSCs were able to benefit myocardial perfusion and contractility, probably by modulating the inflammation and promoting angiogenesis. PMID- 29179178 TI - Serum Cystatin C Predicts AKI and the Prognosis of Patients in Coronary Care Unit: a Prospective, Observational Study. AB - BACKGROUND/AIMS: Acute Kidney Injury (AKI) is a serious clinical state associated with high morbidity and mortality, particularly in critical ill patients. We investigated the hypothesis that serum Cystatin C (sCysC) is a good predictor for AKI and may affect the short-term prognosis of coronary care unit (CCU) patients. METHODS: In this prospective, observational study, we screened 412 adults admitted to the CCU from January 1, 2014 to June 1, 2015 at Zhongnan Hospital of Wuhan University. Serum samples were obtained at the time of admission, and sCysC was quantified through nephelometry. AKI was defined based on KDIGO-AKI criteria. After the patients' hospital discharge, the survivors in this study were followed up for up to 2 years. The primary endpoint was the incidence of AKI stratified by severity stage, while the second endpoints included 2-year mortality, rehospitalization and failure in renal recovery rates, as well as the progression of AKI to CKD. RESULTS: According to the KDIGO-AKI criteria, AKI occurred in 130 (31.6%) patients. After multivariate adjustments, the highest quartile of sCysC was associated with a 9-fold increased risk of incident AKI compared with the lowest quartile. For predicting AKI, sCysC [area under the receiver operating characteristic curve (AUC=0.842)] outperformed beta2-micro globulin (AUC=0.813) and the clinical model (AUC=0.777), and a cutoff of 1.255 mg/L yielded good sensitivity and specificity. After a median 19.8-month follow-up, 112 (27.2%) patients died within 2 years after admission. The sCysC independently predicted the risk of 2-year mortality [adjusted odds ratio (OR), 4.955; 95% confidence interval (95% CI), 2.853 to 8.603] and rehospitalization (OR, 3.128; 95% CI, 2.011 to 4.867), as well as renal recovery failure (OR, 3.618, 95% CI, 1.753 to 7.463). CONCLUSIONS: Serum CysC is a strong predictor of AKI and the short-term prognosis of CCU patients. PMID- 29179179 TI - Naringenin Regulates CFTR Activation and Expression in Airway Epithelial Cells. AB - BACKGROUND/AIMS: Sputum symptoms are commonly seen in the elderly. This study aimed to identify an efficacious expectorant treatment stratagem through evaluating the secretion-promoting activation and cystic fibrosis transmembrane conductance regulator (CFTR) expression of the bioactive herbal monomer naringenin. METHODS: Vectorial Cl- transport was determined by measuring short circuit current (ISC) in rat airway epithelium. cAMP content was measured by ELISA in primary cultured epithelial cells and Calu-3 cells. CFTR expression in Calu-3 cells was determined by qPCR. RESULTS: Addition of naringenin to the basolateral side of the rat airway led to a concentration-dependent sustained increase in ISC. The current was suppressed when exposed to Cl--free solution or by bumetanide, BaCl2, and DPC but not by DIDS and IBMX. Forskolin-induced ISC increase and CFTRinh-172/MDL-12330A-induced ISC inhibition were not altered by naringenin. Intracellular cAMP content was significantly increased by naringenin. With lipopolysaccharide stimulation, CFTR expression was significantly reduced, and naringenin dose-dependently enhanced CFTR mRNA expression. CONCLUSION: These results demonstrate that naringenin has the ability to stimulate Cl- secretion, which is mediated by CFTR through a signaling pathway by increasing cAMP content. Moreover, naringenin can increase CFTR expression when organism CFTR expression is seriously hampered. Our data suggest a potentially effective treatment strategy for sputum. PMID- 29179180 TI - Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio as Prognostic Predictors for Hepatocellular Carcinoma Patients with Various Treatments: a Meta Analysis and Systematic Review. AB - BACKGROUND/AIMS: Systemic inflammatory response (SIR) is widely considered as a preoperative risk factor for hepatocellular carcinoma (HCC) outcomes. The neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR), two of the prognostic indices, have been investigated in post-therapeutic recurrence and survival of HCC. Here, we quantify the prognostic value of these two biomarkers and evaluate their consistency in different HCC therapies. METHODS: A systematic review of electronic database of the Web of Science, Embase, PubMed and the Cochrane Library was conducted to search for associations between the NLR and PLR in the blood and clinical outcomes of HCC. Overall survival (OS) and recurrence-free survival (RFS) were the primary outcomes, and hazard ratios (HRs) and 95% confidence intervals (95% CIs) were explored as effect measures. Subgroup analyses were performed to explore the heterogeneity of different therapies. RESULTS: A total of 24 articles comprising 6318 patients were included in the meta-analysis. Overall, the pooled outcomes revealed that a high NLR before treatment predicted a poor OS (HR: 1.54, 95% CI: 1.34 to 1.76, p<0.001) and poor RFS (HR: 1.45, 95% CI: 1.16 to 1.82, p=0.001). Moreover, an increased PLR predicted a poor OS (HR: 1.63, 95% CI: 1.34 to 1.98, p<0.001) and earlier HCC recurrence (HR: 1.52, 95% CI: 1.21 to 1.91, p<0.001). In addition, both the NLR and PLR were identified as independent risk factors for predicting OS and RFS in HCC patients in a subgroup analysis of different treatment types, including curative or palliative therapy; however, these results were not found in the sorafenib subgroup due to limited clinical research. CONCLUSION: An increased NLR or PLR indicated poor outcomes for patients with HCC. The NLR and PLR may be considered as reliable and inexpensive biomarkers for making clinical decisions regarding HCC treatment. PMID- 29179181 TI - Cysteine-Rich Intestinal Protein 1 Silencing Inhibits Migration and Invasion in Human Colorectal Cancer. AB - BACKGROUND/AIMS: Cysteine-rich intestinal protein 1 (CRIP1), a member of the LIM/double zinc finger protein family, is abnormally expressed in several tumour types. However, few data are available on the role of CRIP1 in cancer. In the present study, we aimed to investigate the expression profile and functions of CRIP1 in colorectal cancer. METHODS: To examine the protein expression level of CRIP1, immunohistochemistry (IHC) was performed on 56 pairs of colon cancer tissue samples. Western blotting was performed to investigate CRIP1 protein expression in four colon cancer cell lines. The endogenous expression of CRIP1 was suppressed using short interfering RNAs (siRNAs). Cell proliferation assays were used to determine whether CRIP1 silencing affected cell proliferation. Flow cytometry analysis was used to detect cell apoptosis. The effects of silencing CRIP1 on cell migration and invasion was detected using the transwell and wound healing assays. RESULTS: IHC analysis showed that protein level of CRIP1 was significantly higher in tumour tissue samples than in paired non-tumour tissue samples and that the CRIP1 level was higher in metastatic tissue samples than in non-metastatic tissue samples. In addition, protein levels of CRIP1 were higher in highly metastatic colon cancer cell lines than in colon cancer cell lines with low metastasis. Further, CRIP1 silencing had no effect on cell proliferation or apoptosis in SW620 and HT29 cells. CRIP1 silencing suppressed cell migration and invasion obviously in SW620 and HT29 cells. CONCLUSION: The present study provides new evidence that abnormal expression of CRIP1 might be related to the degree of metastasis in colorectal cancer and that CRIP1 silencing could effectively inhibit migration and invasion during colorectal cancer development. These findings might aid the development of a biomarker for colon cancer prognosis and metastasis, and thus help to treat this common type of cancer. PMID- 29179182 TI - Therapeutic Effects of FK506 on IgA Nephropathy Rat. AB - BACKGROUND/AIMS: FK506 is an immunosuppressive drug and a calcineurin inhibitor that has been widely used in kidney disease in recent years. FK506 shows a wide range of biological and pharmaceutical effects; however, the mechanism of its anti- proliferative effect has not been well elucidated. An IgA nephropathy (IgAN) model was used to generate a mesangial cell proliferation model. This study aims to examine the effect of FK506 on IgAN rats and the underlying mechanisms. METHODS: Hematuria, proteinuria and renal function were measured. To observe the pathological conditions, we performed HE (hematoxylin - eosin) and PAS (periodic acid - schiff) staining. Transcription and protein expression levels were detected by qRT - PCR (quantitative real-time polymerase chain reaction) and Wb (western blotting). The location and semi-quantitative expression levels of TRPCs, CaN (Calcineurin) and alpha-SMA were examined by IHC (Immunohistochemical staining). RESULTS: We found that FK506 could improve hematuria, proteinuria and renal function, especially in the HF (high-dose FK506) groups. Renal pathological changes were ameliorated in the treatment groups. FK506 could significantly decrease TRPCs, CaN, phosphorylation of ERK1/2 and alpha-SMA expression. CONCLUSION: Taken together, these results suggest that the therapeutic effect of FK506 on IgAN might be partially associated with the down regulated expression of TRPC channels, CaN and phosphorylation of ERK1/2. PMID- 29179183 TI - Long Non-Coding RNAs: the New Horizon of Gene Regulation in Ovarian Cancer. AB - Long non-coding RNAs (lncRNAs), a class of non-coding transcripts, have recently been emerging with heterogeneous molecular actions, adding a new layer of complexity to gene-regulation networks in tumorigenesis. LncRNAs are considered important factors in several ovarian cancer histotypes, although few have been identified and characterized. Owing to their complexity and the lack of adapted molecular technology, the roles of most lncRNAs remain mysterious. Some lncRNAs have been reported to play functional roles in ovarian cancer and can be used as classifiers for personalized medicine. The intrinsic features of lncRNAs govern their various molecular mechanisms and provide a wide range of platforms to design different therapeutic strategies for treating cancer at a particular stage. Although we are only beginning to understand the functions of lncRNAs and their interactions with microRNAs (miRNAs) and proteins, the expanding literature indicates that lncRNA-miRNA interactions could be useful biomarkers and therapeutic targets for ovarian cancer. In this review, we discuss the genetic variants of lncRNAs, heterogeneous mechanisms of actions of lncRNAs in ovarian cancer tumorigenesis, and drug resistance. We also highlight the recent developments in using lncRNAs as potential prognostic and diagnostic biomarkers. Lastly, we discuss potential approaches for linking lncRNAs to future gene therapies, and highlight future directions in the field of ovarian cancer research. PMID- 29179184 TI - Potential Regulatory Effects of Corticotropin-Releasing Factor on Tight Junction Related Intestinal Epithelial Permeability are Partially Mediated by CK8 Upregulation. AB - BACKGROUND/AIMS: Intestinal permeability and stress have been implicated in the pathophysiology of irritable bowel syndrome (IBS). Cytokeratin 8 (CK8), for the first time, has been shown to mediate corticotropin-releasing factor (CRF) induced changes in intestinal permeability in animal models of IBS. In this study, we investigated the regulatory effects of CRF on the permeability of human intestinal epithelial cells through the CK8-mediated tight junction. METHODS: The expression levels of corticotropin-releasing factor receptor 1 (CRFR1) and corticotropin-releasing factor receptor 2 (CRFR2) on the HT29 cell surface were determined by immunofluorescence, RT-PCR, and Western blotting. After treatment with 100 nM CRF for 72 h, the translocation of FITC-labelled dextran was measured in a transwell chamber; the structural changes of tight junctions were observed under transmission electron microscopy; the expression levels of CK8, F-actin and tight junction proteins ZO-1, claudin-1, and occludin were detected by immunoblotting and immunofluorescence. The activity of RhoA was detected by immunoprecipitation. Furthermore, the effects of CRF on intestinal epithelial permeability were examined in CK8-silenced HT29 cells, which were constructed by shRNA interference. RESULTS: CRF treatment increased FITC-labelled dextran permeability, caused the opening of tight junctions, induced increased fluorescence intensity of CK8 and decreased the intensities of ZO-1, claudin-1, and occludin, together with structural disruption. The expression levels of F actin, occludin, claudin-1, and ZO-1 were downregulated. RhoA activity peaked at 30 min after CRF treatment. CRF-induced increased permeability, and downregulation of claudin-1 and occludin were not blocked by CK8 silencing. Nevertheless, CK8 silencing blocked the effects of CRF regarding the decrease in the expression levels of F-action and ZO-1 and increase in RhoA activity. CONCLUSION: CRF may increase intestinal epithelial permeability by upregulating CK8 expression, activating the RhoA signalling pathway, promoting intestinal epithelial actin remodelling, and decreasing the expression of the tight junction protein ZO-1. Other CK8-independent pathways may be involved in the downregulation of claudin-1 and occludin, which might also contribute to increased intestinal epithelial permeability. PMID- 29179185 TI - VEGF-A/Neuropilin 1 Pathway Confers Cancer Stemness via Activating Wnt/beta Catenin Axis in Breast Cancer Cells. AB - BACKGROUND/AIMS: Targeting cancer stem cells (CSCs) is emerging as a promising method for cancer treatment. We previously indicated that knockdown of Neuropilin 1(NRP-1) could inhibit breast cancer cell proliferation. Here, we continue exploring the roles and mechanisms of VEGF-A/NRP-1 axis in breast CSCs formation. METHODS: qRT-PCR was used to detect the levels of VEGF-A and NRP-1 in breast cancer sphere cells and wild-type cells. Mammospheres formation, flow cytometry, soft agar colony and tumor formation assays were performed to evaluate the effects of VEGF-A/NRP-1 on breast cancer stemness. Further HUVECs tube formation, cell invasion assays were carried out to detect the effects of VEGF-A/NRP-1 on breast cancer spheres-induced angiogenesis. Finally, Annexin V/PI apoptosis and CCK8 assays were used to detect the effects of VEGF-A/NRP-1 on chemoresistance. RESULTS: Overexpression of VEGF-A or NRP-1 conferred CSCs-related traits in MCF-7 cells, while knockdown of VEGF-A or NRP-1 reduced CSCs-related traits in MDA-MB 231 cells in vitro and in vivo. Notably, VEGF-A acted in a NRP-1 dependent way. Mechanistically, the VEGF-A/NRP-1 axis conferred CSCs phenotype via activating Wnt/beta-catenin pathway. CONCLUSION: our results suggest that VEGF-A/NRP-1 axis could confer CSCs-related traits and chemoresistance. PMID- 29179186 TI - FNAC: Sampling and Preparation Technique, Fixation, and Staining.

PMID- 29179200 TI - Stress-Kinase Regulation of TASK-1 and TASK-3. AB - BACKGROUND/AIMS: TASK channels belong to the two-pore-domain potassium (K2P) channel family. TASK-1 is discussed to contribute to chronic atrial fibrillation (AFib) and has been together with uncoupling protein 1 found as a marker protein of brown adipose tissue (BAT) fat. In addition, TASK-1 was linked in a genome wide association study to an increased body mass index. A recent study showed that TASK-1 inhibition is causing obesity in mice by a BAT whitening and that these effects are linked to the mineralocorticoid receptor pathway, albeit the mechanism remained elusive. Therefore, we aimed to probe whether K2P channels are regulated by serum- and glucocorticoid-inducible kinases (SGKs) which are known to modify many cellular functions by modulating ion channels. METHODS: To this end we used functional co-expression studies and chemiluminescence-assays in Xenopus oocytes, together with fluorescence imaging and quantitative PCR experiments. RESULTS: SGKs and proteinkinase B (PKB) induced a strong, dose- and time-dependent current reduction of TASK-1 and TASK-3. SGK co-expression reduced the surface expression of TASK-1/3, leading to a predominant localization of the channels into late endosomes. The down regulation of TASK-3 channels was abrogated by the dynamin inhibitor dynasore, confirming a role of SGKs in TASK 1/3 channel endocytosis. CONCLUSION: Stress-mediated changes in SGK expression pattern or activation is likely to alter TASK-1/3 expression at the surface membrane. The observed TASK-1 regulation might contribute to the pathogenesis of chronic AFib and provide a mechanistic link between increased mineralocorticoid levels and TASK-1 reduction, both linked to BAT whitening. PMID- 29179201 TI - Alteration of Tight Junction Protein Expression in Dahl Salt-Sensitive Rat Kidney. AB - BACKGROUND/AIMS: Altered pressure natriuresis is an important mechanism of hypertension, but it remains elusive at the molecular level. We hypothesized that in the kidney, tight junctions (TJs) may have a role in pressure natriuresis because paracellular NaCl transport affects interstitial hydrostatic pressure. METHODS: To assess the association of salt-sensitive hypertension with altered renal TJ protein expression, Dahl salt-sensitive (SS) and salt-resistant (SR) rats were put on an 8% NaCl-containing rodent diet for 4 weeks. Systolic blood pressure (SBP) and urine NaCl excretion were measured weekly, and kidneys were harvested for immunoblotting and quantitative PCR analysis at the end of the animal experiments. RESULTS: SBP was significantly higher in SS rats than in SR rats during the first to fourth weeks of the animal experiments. During the first and second week, urinary NaCl excretion was significantly lower in SS rats as compared with SR rats. However, the difference between the two groups vanished at the third and fourth weeks. In the kidney, claudin-4 protein and mRNA were significantly increased in SS rats as compared with SR rats. On the other hand, occludin protein and mRNA were significantly decreased in SS rats as compared with SR rats. The expression of claudin-2, claudin-7, and claudin-8 did not vary significantly between the two groups. CONCLUSIONS: In SS rats, SS hypertension was associated with differential changes in renal TJ protein expression. Both upregulation of claudin-4 and downregulation of occludin might increase paracellular NaCl transport in the kidney, resulting in impaired pressure natriuresis in SS rats. PMID- 29179202 TI - Long Non-Coding RNA H19 Protects H9c2 Cells against Hypoxia-Induced Injury by Targeting MicroRNA-139. AB - BACKGROUND/AIMS: Acute myocardial infarction (AMI) occurs when blood supply to the heart is diminished (ischemia) for long time; ischemia is primarily caused due to hypoxia. The present study evaluated the effects of long non-coding RNA H19 on hypoxic rat H9c2 cells and mouse HL-1 cells. METHODS: Hypoxic injury was confirmed by measuring cell viability, migration and invasion, and apoptosis using MTT, Transwell and flow cytometry assays, respectively. H19 expression after hypoxia was estimated by qRT-PCR. We then measured the effects of non physiologically expressed H19, knockdown of miR-139 with or without H19 silence, and abnormally expressed Sox8 on hypoxia-induced H9c2 cells. Moreover, the interacted miRNA for H19 and downstream target gene were virtually screened and verified. The involved signaling pathways and the effects of abnormally expressed H19 on contractility of HL-1 cells were explored via Western blot analysis. RESULTS: Hypoxia induced decreases of cell viability, migration and invasion, increase of cell apoptosis and up-regulation of H19. Knockdown of H19 increased hypoxia-induced injury in H9c2 cells. H19 acted as a sponge for miR-139 and H19 knockdown aggravated hypoxia-induced injury by up-regulating miR-139. Sox8 was identified as a target of miR-139, and its expression was negatively regulated by miR-139. The mechanistic studies revealed that overexpression of Sox8 might decrease hypoxia-induced cell injury by activating the PI3K/AKT/mTOR pathway and MAPK. Besides, H19 promoted contractility of HL-1 cells. CONCLUSION: These findings suggest that H19 alleviates hypoxia-induced myocardial cell injury by miR-139-mediated up-regulation of Sox8, along with activation of the PI3K/AKT/mTOR pathway and MAPK. PMID- 29179203 TI - Maternal Hypercholesterolemia Associated with Nicotine Exposure in Adulthood May Induce Kidney Injury in Male Rats if Hypomagnesemia Occurs. AB - BACKGROUND/AIMS: Maternal hypercholesterolemia is a risk factor to renal injury in rat pups at adulthood, especially if they feed a cholesterol-enriched diet after weaning. However, the renal function of male pups of dams with hypercholesterolemia (PH) that were fed a regular chow from weaning to adulthood needs investigation, particularly those exposed to an adverse risk such as nicotine. METHODS: We evaluated the renal function of PH animals and we compared the data with those found in male pups of control dams (PC) at 3- and 6-month-old by inulin clearance. Moreover, we investigated the effect of nicotine treatment for 8 days in both PH and PC animals at 6 months old via metabolic function studies and by renal histological analysis. RESULTS: Inulin clearance and other renal function parameters were similar in PH and PC animals at 3 and 6 months old. Nevertheless, the PH group showed significant differences with regard to histological analysis despite a similar number of glomeruli. The glomerular area of PH animals was significantly smaller than that measured in PC animals, and the fractional interstitial area was significantly larger in PH animals than that measured in PC animals at 3 months old. With regard to nicotine treatment, we observed a trend for a reduction in creatinine clearance in both PC and PH groups, but only PH animals showed hypomagnesemia and the highest fractional interstitial area. CONCLUSIONS: The offspring exposed to a high cholesterol milieu during intrauterine and neonatal life may show a silent kidney injury at adulthood that may be aggravated by nicotine exposure if hypomagnesemia occurs. PMID- 29179204 TI - Clinical Significance of Myeloid Zinc Finger 1 Expression in the Progression of Gastric Tumourigenesis. AB - BACKGROUND/AIMS: To investigate the clinical significance of myeloid zinc finger 1 (MZF1) expression in various gastric mucosal lesions including chronic superficial gastritis (CSG), chronic atrophic gastritis (CAG), intestinal metaplasia (IM), dysplasia (DYS) and gastric cancer (GC) in comparison with normal tissues and gastric cell lines. METHODS: MZF1 protein expression was detected using immunohistochemical staining in 37 CSG, 88 CAG, 77 IM, 51 DYS, 165 GC and 8 normal tissue samples. Quantitative real-time PCR (qRT-PCR) and western blotting were used to detect the level of MZF1 in gastric cell lines, 15 normal tissues and 34 GC samples, as well as 2 groups of paired primary GC and adjacent normal samples. RESULTS: Reduced MZF1 expression was detected in most GC cells and tissues. Among the gastric tissues consisting of various stages of lesions (normal, CSG, CAG, IM, DYS and GC), MZF1 protein expression was downregulated in precancerous lesions and GC. The data from clinical analyses showed that decreased MZF1 expression was correlated with tumour invasion (p = 0.044), lymph node metastasis (p = 0.048) and poor prognosis of GC patients (p = 0.003). Moreover, MZF1 was identified as an independent prognostic biomarker for GC patients in multivariate Cox regression analysis (p = 0.009). CONCLUSION: Downregulation of MZF1 was associated with gastric tumourigenesis, which may be a novel early predictive and prognostic biomarker in GC patients. PMID- 29179205 TI - Overexpression of TIMP3 Protects Against Cardiac Ischemia/Reperfusion Injury by Inhibiting Myocardial Apoptosis Through ROS/Mapks Pathway. AB - BACKGROUND/AIMS: Myocardial ischemia/reperfusion (I/R) injury remains a great challenge in clinical therapy. Tissue inhibitor of metalloproteinases 3 (TIMP3) plays a crucial role in heart physiological and pathophysiological processes. However, the effects of TIMP3 on I/R injury remain unknown. METHODS: C57BL/6 mice were infected with TIMP3 adenovirus by local delivery in myocardium followed by I/R operation or doxorubicin treatment. Neonatal rat cardiomyocytes were pretreated with TIMP3 adenovirus prior to anoxia/reoxygenation (A/R) treatment in vitro. Histology, echocardiography, in vivo phenotypical analysis, flow cytometry and western blotting were used to investigate the altered cardiac function and underlying mechanisms. RESULTS: The results showed that upregulation of TIMP3 in myocardium markedly inhibited myocardial infarct areas and the cardiac dysfunction induced by I/R or by doxorubicin treatment. TUNEL staining revealed that TIMP3 overexpression attenuated I/R-induced myocardial apoptosis, accompanied by decreased Bax/Bcl-2 ratio, Cleaved Caspase-3 and Cleaved Caspase-9 expression. In vitro, A/R-induced cardiomyocyte apoptosis was abrogated by pharmacological inhibition of reactive oxygen species (ROS) production or MAPKs signaling. Attenuation of ROS production reversed A/R-induced MAPKs activation, whereas MAPKs inhibitors showed on effect on ROS production. Furthermore, in vivo or in vitro overexpression of TIMP3 significantly inhibited I/R- or A/R-induced ROS production and MAPKs activation. CONCLUSION: Our findings demonstrate that TIMP3 upregulation protects against cardiac I/R injury through inhibiting myocardial apoptosis. The mechanism may be related to inhibition of ROS-initiated MAPKs pathway. This study suggests that TIMP3 may be a potential therapeutic target for the treatment of I/R injury. PMID- 29179206 TI - Hybrid Complexes of High and Low Molecular Weight Hyaluronans Highly Enhance HASCs Differentiation: Implication for Facial Bioremodelling. AB - BACKGROUND/AIMS: Adipose-derived Stem Cells (ASCs) are used in Regenerative Medicine, including fat grafting, recovery from local tissue ischemia and scar remodeling. The aim of this study was to evaluate hyaluronan based gel effects on ASCs differentiation and proliferation. METHODS: Comparative analyses using high (H) and low (L) molecular weight hyaluronans (HA), hyaluronan hybrid cooperative complexes (HCCs), and high and medium cross-linked hyaluronan based dermal fillers were performed. Human ASCs were characterized by flow cytometry using CD90, CD34, CD105, CD29, CD31, CD45 and CD14 markers. Then, cells were treated for 7, 14 and 21 days with hyaluronans. Adipogenic differentiation was evaluated using Oil red-O staining and expression of leptin, PPAR-gamma, LPL and adiponectin using qRT-PCR. Adiponectin was analyzed by immunofluorescence, PPAR gamma and adiponectin were analyzed using western blotting. ELISA assays for adiponectin and leptin were performed. RESULTS: HCCs highly affected ASCs differentiation by up-regulating adipogenic genes and related proteins, that were also secreted in the culture medium. H-HA and L-HA induced a lower level of ASCs differentiation. CONCLUSION: HCCs-based formulations clearly enhance adipogenic differentiation and proliferation, when compared with linear HA and cross-linked hyaluronans. Injection of HCCs in subdermal fat compartment may recruit and differentiate stem cells in adipocytes, and considerably improving fat tissue renewal. PMID- 29179207 TI - Reduction of NANOG Mediates the Inhibitory Effect of Aspirin on Tumor Growth and Stemness in Colorectal Cancer. AB - BACKGROUND/AIMS: Cancer stem cells (CSCs) are considered to be responsible for tumor relapse and metastasis, which serve as a potential therapeutic target for cancer. Aspirin has been shown to reduce cancer risk and mortality, particularly in colorectal cancer. However, the CSCs-suppressing effect of aspirin and its relevant mechanisms in colorectal cancer remain unclear. METHODS: CCK8 assay was employed to detect the cell viability. Sphere formation assay, colony formation assay, and ALDH1 assay were performed to identify the effects of aspirin on CSC properties. Western blotting was performed to detect the expression of the stemness factors. Xenograft model was employed to identify the anti-cancer effects of aspirin in vivo. Unpaired Student t test, ANOVA test and Kruskal Wallis test were used for the statistical comparisons. RESULTS: Aspirin attenuated colonosphere formation and decreased the ALDH1 positive cell population of colorectal cancer cells. Aspirin inhibited xenograft tumor growth and reduced tumor cells stemness in nude mice. Consistently, aspirin decreased the protein expression of stemness-related transcription factors, including c Myc, OCT4 and NANOG. Suppression of NANOG blocked the effect of aspirin on sphere formation. Conversely, ectopic expression of NANOG rescued the aspirin-repressed sphere formation, suggesting that NANOG is a key downstream target. Moreover, we found that aspirin repressed NANOG expression in protein level by decreasing its stability. CONCLUSION: We have provided new evidence that aspirin attenuates CSC properties through down-regulation of NANOG, suggesting aspirin as a promising therapeutic agent for colorectal cancer treatment. PMID- 29179208 TI - KLF 15 Works as an Early Anti-Fibrotic Transcriptional Regulator in Ang II Induced Renal Fibrosis via Down-Regulation of CTGF Expression. AB - BACKGROUND/AIMS: Angiotensin II (Ang II) has been regarded as an important profibrogenic cytokine in renal fibrosis. Kruppel-like factor 15 (KLF15) has been identified as an important negative transcription factor in renal fibrosis. However, little is known about the role of KLF15 in Ang II-induced renal fibrosis. METHODS: In this study, we randomized mice into a control group, Ang II group or Ang II plus losartan group. KLF15 expression was examined with real-time PCR and immunofluorescence in these groups. In vitro, KLF15 expression was examined by Western blot in rat renal fibroblasts (NRK-49F) stimulated with Ang II, and the effect of altered KLF15 expression on the regulation of the profibrotic factor connective tissue growth factor (CTGF) was further explored with co-immunoprecipitation (CoIP) and chromatin immunoprecipitation (ChIP) analyses. RESULTS: Compared with the control group, the murine model of Ang II induced renal fibrosis demonstrated a significant decrease in renal KLF15 expression at 4 weeks and presented with progressive renal fibrosis at 6 weeks. Meanwhile, losartan, an angiotensin type 1 (AT1) receptor antagonist, effectively prevented the down-regulation of KLF15 expression induced by Ang II infusion. In vitro, NRK-49F cells stimulated with Ang II exhibited a significant decrease in KLF15 expression, accompanied by a marked increase in the expression of profibrotic factors and in the production of extracellular matrix. The up regulation of CTGF expression induced by Ang II stimulation was inhibited by KLF15 overexpression in NRK-49F cells, and losartan treatment prevented the down regulation of KLF15 expression and the up-regulation of CTGF expression induced by Ang II stimulation. Furthermore, CoIP and ChIP assays revealed that the transcription regulator KLF15 directly bound to the co-activator P/CAF and repressed its recruitment to the CTGF promoter. CONCLUSIONS: Ang II down regulates KLF15 expression via the AT1 receptor, and KLF15 is likely to inhibit Ang II-induced CTGF expression by repressing the recruitment of the co-activator P/CAF to the CTGF promoter. PMID- 29179209 TI - Calycosin Suppresses Epithelial Derived Initiative Key Factors and Maintains Epithelial Barrier in Allergic Inflammation via TLR4 Mediated NF-kappaB Pathway. AB - BACKGROUND/AIMS: Calycosin is a bioactive component of Astragali Radix, a Chinese herb for treating allergy. We have previously demonstrated that calycosin effectively inhibited allergic inflammation efficiently. The aim of this study was to explore the mechanism of calycosin on epithelial cells in allergic inflammation. METHODS: An initial stage of atopic dermatitis (AD) model in which mice were just sensitized with FITC, was established in vivo and immortalized human keratinocytes (HaCaT cells) were utilized in vitro. Initiative key cytokines, TSLP and IL-33, were measured by ELISA, qPCR, immunofluorescence and Western blot. The junctions in epithelial cells were observed by electron microscopy and tight junctions (TJs) (Occludin and ZO-1) were assessed by Western blot and immunofluorescence. TLR4, MyD88, TAK1, TIRAP and NF-kappaB were measured by qPCR or Western blot. RESULTS: The results showed that TSLP and IL-33 were inhibited significantly by calycosin in the initial stage of AD model. Simultaneously, calycosin attenuated the separated gap among the epithelial cells and increased the expression of TJs. TSLP/IL-33 and TJs were similarly affected in LPS-stimulated HaCaT cells in vitro. Meanwhile, calycosin not only inhibited the expressions of TLR4, MyD88, TAK1 and TIRAP, but also reduced NF-kappaB activation in vitro and in vivo. An NF-kappaB inhibitor enhanced the expressions of TJs and reduced that of TSLP/IL-33 in LPS-stimulated HaCaT cells. CONCLUSION: These results indicated that calycosin reduced the secretion of TSLP/IL-33 and attenuated the disruption of epithelial TJs by inhibiting TLR4 mediated NF-kappaB signaling pathway. These findings help to understand the beneficial effects of calycosin on AD, and to develop effective preventive or therapeutic strategies to combat this disease and other epithelial barrier deletion-mediated allergic diseases. PMID- 29179210 TI - ENaCs as Both Effectors and Regulators of MiRNAs in Lung Epithelial Development and Regeneration. AB - Epithelial sodium channels (ENaC) play an important role in re-absorbing excessive luminal fluid by building up an osmotic Na+ gradient across the tight epithelium in the airway, the lung, the kidney, and the colon. The ENaC is a major pathway for retention of salt in kidney too. MicroRNAs (miRs), a group of non-coding RNAs that regulate gene expression at the post-transcriptional level, have emerged as a novel class of regulators for ENaC. Given the ENaC pathway is crucial for maintaining fluid homeostasis in the lung and the kidney and other cavities, we summarized the cross-talk between ENaC and miRs and recapitulated the underlying regulatory factors, including aldosterone, transforming growth factor-beta1, and vascular endothelial growth factor-A in the lung and other epithelial tissues/organs. We have compared the profiling of miRs between normal and injured mice and human lungs, which showed a significant alteration in numerous miRs in mouse models of LPS and ventilator induced ARDS. In addition, we reiterated the potential regulation of the ENaC by miRs in stem/ progenitor cell based re-epithelialization, and identified a promising pharmaceutic target of ENaC for removing edema fluid in ARDS by mesenchymal stem cells-released paracrine. In conclusion, it seems that the interactions between miRs and scnn1s/ENaCs are critical for lung development, epithelial cell turnover in adult lungs, and re-epithelialization for repair. PMID- 29179211 TI - Molecular Mechanism of MiR-136-5p Targeting NF-kappaB/A20 in the IL-17-Mediated Inflammatory Response after Spinal Cord Injury. AB - BACKGROUND/AIMS: The pathophysiology of spinal cord injury (SCI) results in serious damage to the human body via an increase in the secondary biological processes imposed by activated astrocytes. Abnormal expression of microRNAs after SCI has become a potential research focus. However, the underlying mechanisms are poorly understood. METHODS: SCI models were established in rats using Allen's method, and the BBB scoring method was employed to assess locomotor function. Lentivirus was used to infect rat astrocytes and SCI rats. Real-time PCR and antibody chip were used to measure gene expression and cytokine secretion. Western blot analysis was employed to detect protein expression. HE staining was used to assess the histological changes in SCI. The immunohistochemical staining of A20 and p-NF-kappaB in SCI was also analyzed. RESULTS: The in vitro experiment showed that miR-136-5p up-regulated the expression of p-NF-kappaB by down regulating the expression of A20 so that astrocytes produced inflammatory factors and chemokines. The in vivo experiment indicated that overexpressed miR-136-5p promoted the production of inflammatory factors, chemokines and p-NF-kappaB in SCI rats, whereas it inhibited the expression of A20 protein and increased inflammatory cell infiltration and injuries in the spinal cord. CONCLUSION: The current findings indicate that silencing miR-136-5p effectively decreased inflammatory factors and chemokines and protected the spinal cord via NF kappaB/A20 signaling in vivo and in vitro. In contrast, overexpression of miR-136 5p had the opposite effect. PMID- 29179212 TI - LukS-PV-Regulated MicroRNA-125a-3p Promotes THP-1 Macrophages Differentiation and Apoptosis by Down-Regulating NF1 and Bcl-2. AB - BACKGROUND/AIMS: LukS-PV is a component of Panton-Valentine leukocidin (PVL). We have previously demonstrated that LukS-PV potently promoted differentiation and induced apoptosis in THP-1 cells. However, the precise mechanisms of these actions remain unknown. MicroRNAs (miRs) play important roles in cellular differentiation and apoptosis. This study aimed to investigate the role of miR 125a-3p in LukS-PV-regulated differentiation and apoptosis and its underlying mechanism in THP-1 cells. METHODS: MicroRNA profiling analyses were conducted to determine differential miRNA expression levels in THP-1 cells treated with LukS PV. Cell differentiation and apoptosis were measured in THP-1 cells by gain-of function and loss-of-function experiments. Bioinformatics analysis and luciferase reporter assays were used to confirm the targets of miR-125a-3p. The effects of the miR-125a-3p targets on cellular differentiation were determined by knocking them down. RESULTS: MiR-125a-3p was up-regulated after treating the human monocytic leukaemia cell line THP-1 with LukS-PV. In addition, miR-125a-3p positively regulated apoptosis and differentiation in THP-1 cells treated with LukS-PV. Concordantly, luciferase reporter assays confirmed that neurofibromatosis type 1 (NF1) and B-cell lymphoma 2 (Bcl-2) were direct target genes of miR-125a-3p. Moreover, NF1 knockdown in THP-1 cells significantly promoted differentiation in vitro. Finally, the extracellular signal-regulated kinase (ERK) pathway, a downstream target of NF1, was activated after NF1 knockdown. CONCLUSIONS: These findings confirm that miR-125a-3p is involved in LukS-PV-mediated cell differentiation and apoptosis in THP-1 cells. PMID- 29179213 TI - Melanotic Neuroectodermal Tumor of Infancy of the Upper Arm. AB - OBJECTIVE: To present a case of a 6-month-old infant with melanotic neuroectodermal tumor of infancy (MNTI) in the upper arm. CLINICAL PRESENTATION AND INTERVENTION: A 6-month-old female presented with a well-circumscribed lesion of the upper arm at the Children's Hospital Zagreb. A biopsy was performed and microscopy revealed 2 cell populations consisting of small neuroblastic cells and larger melanin-containing epithelial cells. An excisional biopsy performed 1 month later confirmed the initial diagnosis of MNTI, but the tumor had increased in size since the initial biopsy. After complete surgical excision the patient recovered well with no recurrence. CONCLUSION: The MNTI located in the upper arm was diagnosed on first biopsy and surgically excised completely. The patient recovered without recurrence in a follow-up of 2.5 years. PMID- 29179214 TI - Cetuximab Enhanced the Cytotoxic Activity of Immune Cells during Treatment of Colorectal Cancer. AB - BACKGROUND/AIMS: Cetuximab is a chimeric IgG1 monoclonal antibody which targets the extracellular domain of epidermal growth factor receptor. This antibody is widely used for colorectal cancer (CRC) treatment but its influence on the immune system is incompletely understood. METHODS: The immune influence of cetuximab therapy in CRC patients was investigated by analyzing peripheral blood mononuclear cells using flow cytometry. We undertook in vitro cytotoxicity and cytokine-profile assays to ascertain the immunomodulatory effect of cetuximab treatment. RESULTS: The number of CD3+ T, CD8+ T, and natural killer (NK) cells was increased significantly and T-regulatory cells reduced gradually after cetuximab treatment. Percentage of CD4+ T, natural killer T (NKT)-like, invariant NKT, and dendritic cells was similar between baseline patients and cetuximab patients. Expression of CD137 on NK and CD8+ T cells was increased significantly after 4 weeks of cetuximab therapy. In vitro cetuximab treatment markedly increased expression of CD137 and CD107a on NK and CD8+ T cells. Cetuximab treatment promoted the cytotoxic activity of NK and CD8+ T cells against tumor cells. CONCLUSION: Cetuximab treatment promotes activation of the immune response but alleviates immunosuppression: this might be the underlying anti-CRC effect of cetuximab. PMID- 29179215 TI - Long Non-Coding RNA Linc-USP16 Functions As a Tumour Suppressor in Hepatocellular Carcinoma by Regulating PTEN Expression. AB - BACKGROUND/AIMS: Recent evidence has indicated the crucial regulatory roles of long non-coding RNAs (lncRNAs) in tumour biology. In hepatocellular carcinoma (HCC), aberrant expression of lncRNAs plays an essential role in HCC tumourigenesis. However, the potential roles and regulatory mechanisms of the novel human lncRNA, Linc-USP16, in HCC are unclear. METHODS: To investigate the function of Linc-USP16 in HCC, we first analysed the expression levels of Linc USP16 in HCC patient tissues and cell lines via q-RT-PCR and established overexpressed or knockdown HCC cell lines. RESULTS: Here, we found that Linc USP16 expression was significantly down-regulated in HCC patient tissues and cell lines. Further functional experiments suggested that Linc-USP16 could directly increase PTEN expression by acting as a competing endogenous RNA (ceRNA) for miR 21 and miR-590-5p. These interactions led to repression of AKT pathway and inhibition of HCC cell proliferation and migration. CONCLUSION: Thus, our data showed that Linc-USP16, as a tumour suppressor, plays an important role in HCC pathogenesis and provides a new therapeutic strategy for HCC treatment. PMID- 29179216 TI - Heat Shock Protein 70 Negatively Regulates TGF-beta-Stimulated VEGF Synthesis via p38 MAP Kinase in Osteoblasts. AB - BACKGROUND/AIMS: We previously demonstrated that transforming growth factor-beta (TGF-beta) stimulates the synthesis of vascular endothelial growth factor (VEGF) through the activation of p38 mitogen-activated protein (MAP) kinase in osteoblast-like MC3T3-E1 cells. Heat shock protein70 (HSP70) is a ubiquitously expressed molecular chaperone. In the present study, we investigated the involvement of HSP70 in the TGF-beta-stimulated VEGF synthesis and the underlying mechanism in these cells. METHODS: Culture MC3T3-E1 cells were stimulated by TGF beta. Released VEGF was measured using an ELISA assay. VEGF mRNA level was quantified by RT-PCR. Phosphorylation of each protein kinase was analyzed by Western blotting. RESULTS: VER-155008 and YM-08, both of HSP70 inhibitors, significantly amplified the TGF-beta-stimulated VEGF release. In addition, the expression level of VEGF mRNA induced by TGF-beta was enhanced by VER-155008. These inhibitors markedly strengthened the TGF-beta-induced phosphorylation of p38 MAP kinase. The TGF-beta-induced phosphorylation of p38 MAP kinase was amplified in HSP70-knockdown cells. SB203580, an inhibitor of p38 MAP kinase, significantly suppressed the amplification by these inhibitors of the TGF-beta induced VEGF release. CONCLUSION: These results strongly suggest that HSP70 acts as a negative regulator in the TGF-beta-stimulated VEGF synthesis in osteoblasts, and that the inhibitory effect of HSP70 is exerted at a point upstream of p38 MAP kinase. PMID- 29179217 TI - Ellagic Acid Reduces High Glucose-Induced Vascular Oxidative Stress Through ERK1/2/NOX4 Signaling Pathway. AB - BACKGROUND/AIMS: Elevated production of reactive oxygen species (ROS) is linked to endothelial dysfunction and is one of the key contributors to the pathogenesis of diabetic vascular complications. Emerging evidence has indicated that ellagic acid (EA), a polyphenol found in fruits and nuts, possesses numerous biological activities including radical scavenging. However, whether EA exerts a vasculo protective effect via antioxidant mechanisms in blood vessels exposed to diabetic conditions remains unknown. Accordingly, the goal of this current study was to determine whether EA decreases vascular ROS production and thus ameliorates endothelial dysfunction in the diabetic milieu. METHODS: Intact rat aortas and human aortic endothelial cells (HAEC) were stimulated with 30mM high glucose (HG) with and without EA co-treatment. Endothelium-dependent vasodilation was measured using a wire myograph. Gene and protein expression of non-phagocytic nicotinamide adenine dinucleotide phosphate (NADPH) oxidases 4 (NOX4) were detected using RT PCR and western blotting, respectively. Oxidative stress was determined by measuring ROS levels using dihydroethidium (DHE) staining. RESULTS: Intact aortas exposed to HG condition displayed exacerbated ROS production and impairment of endothelium-dependent vasodilation, characterizing endothelial dysfunction. These effects were markedly reduced with EA treatment. HG enhanced ROS production in HAEC, paralleled by increased ERK1/2 activation and NOX4 expression. EA treatment blunted the increase of ROS generation, ERK1/2 activation and decreased NOX4. CONCLUSIONS: EA significantly decreases endothelial ROS levels and ameliorates the impairment of vascular relaxation induced by HG. Our results suggest that EA exerts a vasculo-protective effect under diabetic conditions via an antioxidant effect that involves inhibition of ERK1/2 and downregulation of NOX4. PMID- 29179218 TI - Puerarin Enhances Ca2+ Reuptake and Ca2+ Content of Sarcoplasmic Reticulum in Murine Embryonic Stem Cell-Derived Cardiomyocytes via Upregulation of SERCA2a. AB - BACKGROUND/AIMS: The embryonic stem cell-derived cardiomyocytes (ES-CMs) serve as potential sources for cardiac regenerative therapy. However, the immature sarcoplasmic reticulum (SR) function of ES-CMs prevents its application. In this report, we examined the effect of puerarin, an isoflavone compound, on SR function of murine ES-CMs. METHODS: Murine ES-CMs were harvested by embryoid body based differentiation method. Confocal calcium imaging and whole-cell patch clamps were performed to assess the function of SR. The mRNA expression levels of SR-related genes were examined by quantitative PCR. The protein expression of sarcoplasmic reticulum calcium-ATPase 2a (SERCA2a) was evaluated by immunofluorescent and western blot. RESULTS: Long-term application of puerarin promotes basic properties of spontaneous calcium transient with increased amplitude, decay velocity, and decreased duration. Puerarin fails to alter ICa,L but increases the Ca2+ content of SR. Puerarin-treated ES-CMs have intact SR Ca2+ cycling with more SR Ca2+ reuptake. Long-term application of puerarin asynchronously upregulates the mRNA and protein expression of SERCA2a, as well as the transcripts of calsequestrin and triadin in developing ES-CMs. Application of puerarin during the stage of post-cardiac differentiation upregulates dose dependently the transcripts of SERCA2a, phospholamban and tridin which can be reversed by the inhibitors of the PI3K/Akt and MAPK/ERK signaling pathways, but shows no effect on the protein expression of SERCA2a. CONCLUSION: This study demonstrates that long-term puerarin treatment enhances Ca2+ reuptake and Ca2+ content via upregulation of SERCA2a.

PMID- 29179219 TI - A Molecular Signature of Two Long Non-Coding RNAs in Peripheral Blood Predicts Acute Renal Allograft Rejection. AB - BACKGROUND/AIMS: Acute rejection (AR) is a major complication post renal transplantation, with no widely-accepted non-invasive biomarker. This study aimed to explore the expression profiles of long non-coding RNAs (lncRNAs) in the peripheral blood (PB) of renal transplant recipients and their potential diagnostic values. METHODS: The genome-wide lncRNA expression profiles were analyzed in 150 PB samples from pediatric and adult renal transplant (PRTx and ARTx) cohorts. The diagnostic performance of differentially expressed lncRNA was determined using receiver operator characteristic curve, with area under the curve (AUC) and 95% confidential interval (CI). Finally, a risk score was constructed with logistical regression model. RESULTS: A total of 162 lncRNAs were found differentially expressed in PRTx cohort, while 163 in ARTx cohort. Among these identified lncRNAs, 23 deregulated accordingly in both cohorts, and could distinguish AR recipients from those without AR. Finally, a risk score with two most significant lncRNAs (AF264622 and AB209021) was generated and exhibited excellent diagnostic performance in both PRTx (AUC:0.829, 95% CI:0.735-0.922) and ARTx cohorts (AUC: 0.889, 95% CI: 0.817-0.960). CONCLUSION: A molecular signature of two lncRNAs in PB could serve as a novel non-invasive biomarker for the diagnosis of AR in both pediatric and adult renal transplant recipients. PMID- 29179221 TI - [Vitreomacular Traction Following Anti-VEGF Therapy - Two Cases]. AB - Vitreomacular traction syndrome (VMTS) is defined as an incomplete or anomalous posterior vitreous detachment resulting in tractional forces at the macular region. In the context of anti-VEGF therapy, the formation of vitreoretinal traction has mainly been reported as a potential complication of VEGF inhibition in ischemic proliferative retinal disease, such as proliferative diabetic retinopathy. In this report, we present two patients who developed VMTS during anti-VEGF therapy for exudative age-related macular degeneration and diabetic macular edema. VMTS following anti-VEGF therapy of exudative macular diseases is rare. The exact pathomechanism remains unclear. However, there is a hypothesis that in eyes with adherent vitreous cortex, the induction of fibrosis as a result of the VEGF inhibition may lead to vitreomacular traction. PMID- 29179222 TI - Gap-Balancing versus Measured Resection Technique in Total Knee Arthroplasty: A Comparison Study. AB - Proper femoral component alignment in the axial plane during total knee arthroplasty (TKA) depends on accurate bone cuts and soft tissue balancing. Two methods that are used to achieve this are "measured resection" and "gap balancing." However, a controversy exists as to which method is more accurate and leads to better outcomes. Therefore, the purpose of this study was to evaluate: (1) implant survivorship, (2) patient outcomes, (3) complications, and (4) radiographic analysis comparing patients who underwent TKA with either gap balancing or measured resection techniques. A total of 214 consecutive patients (221 knees) underwent primary TKA by a single surgeon between 2011 and 2012. Component alignment was achieved by using measured resection in 116 knees and gap balancing was used in 105 knees. The patients had a mean age of 66 years (range, 44-86 years) and a mean body mass index of 32 kg/m2 (range, 22-52 kg/m2). Patient range-of-motion (ROM) and Knee Society (KS) function and pain scores, and radiographic assessment, were assessed preoperatively and postoperatively at ~6 weeks, 3 months, 1 year, and then annually. The mean follow-up time was 3 years. A Kaplan-Meier's analysis was performed to calculate the survivorship. The aseptic survivorship was 98% in both the measured resection and gap-balancing groups. The mean ROM was not significantly different between the measured resection and gap-balancing groups (123 vs. 123 degrees, p = 0.990). There were no significant differences between the two groups in terms of the KS function scores (86 vs. 85 points, p = 0.829) or the KS pain scores (93 vs. 92 points, p = 0.425). Otherwise, the radiographic evaluation at latest follow-up did not demonstrate any evidence of progressive radiolucencies or loosening, of any prosthesis. The results of this study found that at a mean follow-up of 3 years, both the measured resection and gap-balancing techniques achieved excellent survivorship and postoperative outcomes. This demonstrates that both methods can be used to achieve accurate femoral component alignment with similar short-term outcomes. PMID- 29179223 TI - Coronal Correction for Severe Deformity Using Robotic-Assisted Total Knee Arthroplasty. AB - Although robotic-assisted total knee arthroplasty (TKA) has the potential to accurately reproduce neutral alignment, it is still unclear if this correction is attainable in patients who have severe varus or valgus deformities. Therefore, the purpose of this study was to assess a single surgeon's experience with correcting coronal deformities using the robotic-assisted TKA device. Specifically, we looked at correction of varying degrees of varus and valgus deformity in patients who underwent robotic arm-assisted TKA. A total of 330 robotic-assisted TKA cases performed by a single surgeon were analyzed. Preoperative CT scans were registered to the robotic-assisted software to create a three-dimensional rendering from which coronal alignment was measured. Postoperative coronal alignment measurements were taken in the operating room using the robotic-assisted device after trial component placement. The robotic assisted device uses optical tracking from navigation probes placed on the distal femur and proximal tibia. The robotic-assisted software can register these probes as bony landmarks to measure coronal alignment in the distal plane of the femoral component and proximal plane of the tibial component. A total of 261 cases were of varus knees, 46 cases were of valgus knees, and 23 cases had 0 degrees preoperative alignment. Severe deformity was defined as 7 degrees or greater deformity. Preoperative neutral alignment was defined as 0 degrees , while postoperative neutral alignment was defined as 0 degrees +/- 3 degrees . There were 129 patients with and initial severe varus and 7 patients with an initial severe valgus deformity of 7 degrees or greater. Patients were divided into varus or valgus cohorts, and analysis was performed on the overall cohort, as well as nonsevere (<7 degrees ) and severe (7 degrees or greater) deformity cohorts.All 132 knees with initial varus deformity of less than 7 degrees were corrected to neutral (mean 1 degrees , range -1-3 degrees ). A total of 82 knees (64%) with 7 degrees or greater varus deformity were corrected to neutral (mean 2 degrees , range 0-3 degrees ). However, roughly 30% of patients with severe deformity who were not corrected to neutral were still corrected within a couple of degrees of neutral. There were seven knees with 7 degrees or greater valgus deformity, and all were corrected to neutral (mean 2 degrees , range 0-3 degrees ). This study demonstrated that all knees were corrected in the appropriate direction within a few degrees of neutral, and no knees were overcorrected. The implication of this ability to achieve alignment goals on clinical outcomes will need to be evaluated in future studies. The results from this study demonstrate the potential for the robotic-assisted device during TKA in helping surgeons achieve a preoperatively planned desired neutral alignment. PMID- 29179224 TI - Evaluation of the Implantable Doppler Probe for Free Flap Monitoring in Lower Limb Reconstruction. AB - BACKGROUND: Timely reexploration and reanastomoses can salvage failing free flaps. The use of the implantable Doppler probe provides direct evidence of vascular impairment of the microvascular anastomoses and allows for postoperative NPWT. The aim of this retrospective study was to compare the Doppler probe to conventional monitoring techniques for free flap monitoring in lower limb reconstruction and to identify risk factors for perfusion disturbance and reexploration. METHODS: All patients receiving free muscle flap reconstruction for lower limb soft tissue defects at our department from 2000 to 2013 were included, and all adverse events, timely detection of perfusion problems, and outcome of revision surgery were assessed by chart analysis. RESULTS: For lower limb reconstruction, 110 free muscle transfers were performed of which 41 muscle flaps were conventionally monitored and 69 flaps were monitored using the implantable Doppler probe. In 18 cases, the free muscle flaps needed revision because of perfusion disturbances. The salvage rate was 80% with monitoring by the implantable Doppler probe compared with 62.5% using conventional monitoring methods resulting in success rates of 95.7 and 92.7%, respectively. CONCLUSION: The use of the implantable Cook-Swartz Doppler probe represents a safe monitoring method for lower limb reconstruction, which allows for the additional use of NPWT. Higher salvage and revision success rates can be attributed to an earlier detection of perfusion impairment. However, a larger patient cohort is necessary to verify superiority over conventional postoperative monitoring. PMID- 29179225 TI - Staged Reconstruction (Delayed-Immediate) of the Maxillectomy Defect Using CAD/CAM Technology. AB - BACKGROUND: Computer-aided design/computer-aided manufacturing (CAD/CAM) technology has become increasingly popular for free fibula reconstruction of the mandible. The same technology, however, has not been widely utilized in immediate complex midface reconstruction utilizing free fibula flaps. Maxillary defects are difficult to precisely predict or produce matched cutting guides for after the ablative surgery. We present a protocol for "delayed-immediate" two-stage reconstruction for complex mid-facial defects, by delaying lymph node neck dissection and using CAD/CAM technology for delayed bony reconstruction. METHODS: Stage 1 includes the extirpative surgery, placement of a temporary obturator, and an immediate post-excision fine cut computed tomography (CT) of the defect that is used for CAD/CAM planning. The time interval between stages is used for virtual surgical planning (VSP) and provides an opportunity for the final pathologic margins to be evaluated. At stage 2, definitive reconstruction is performed in conjunction with the delayed neck dissection. Briefly delaying the neck dissection until stage 2 allows for recipient vessel dissection and microsurgical anastomoses to safely occur in a surgically naive neck. CONCLUSION: A two-stage delayed-immediate reconstruction of complex mid-face defects can be safely and effectively performed. This protocol takes advantage of advancing CAD/CAM technology, provides an opportunity to evaluate final margins, and avoids recipient vessel dissection and microsurgery in previously operated or irradiated necks. PMID- 29179226 TI - Leptin and its Relation to Autonomic Activity, Endothelial Cell Activation and Blood Pressure in a Young Black and White Population: The African-PREDICT study. AB - An increasing prevalence of obesity-related hypertension is observed in the youth and may have severe consequences for future cardiovascular disease development. Previous studies portrayed leptin as a potential factor involved in obesity related hypertension development. In order to understand leptin's contributions to early cardiovascular deterioration, we investigated leptin and its associations with measures of autonomic activity, endothelial activation, and blood pressure in young healthy black and white men and women. We included 820 participants (aged 20-30 years) and determined serum leptin and endothelial cellular adhesion molecules. We measured 24-h blood pressure, heart rate, and heart rate variability components. In multivariate-adjusted regression analyses, we found consistent associations between markers of autonomic activity (such as 24-h heart rate, day and night-time heart rate as well as heart rate variability total power) and leptin in both white (all p<=0.001) and black men (all p<=0.040). These findings were absent or less prominent in women, despite their almost 10-fold higher leptin levels than men. Only in white men, 24-h diastolic blood pressure was associated with leptin (Std beta=0.37; p=0.006). This association was found to be partly mediated by autonomic activity (24-h heart rate variability total power). No independent associations were observed between leptin and markers of endothelial cell activation, irrespective of race or gender. Leptin's independent association with autonomic neural activity in a young apparently healthy population suggests an early influence of leptin on autonomic function and future blood pressure elevation especially in men. PMID- 29179227 TI - [On the risk of dependence on gabapentinoids]. AB - In the last ten years, the prescriptions of the gabapentinoids gabapentin and pregabalin increased largely also in Germany. Since several national and international pharmacovigilance-databases have warned for abuse liabilities and overdose fatalities in association with both gabapentinoids, which moreover, became to be sold on internet and black-markets, their addictive power has been subject to an ongoing clinical debate. As pre- and post-approval clinical trials did not reveal significant signs of dependence on gabapentin or pregabalin, we systematically searched in PubMed and Scopus for clinical studies and case reports being associated with abuse of and dependence on these drugs. We found 14 clinical-epidemiologic studies and 38 case reports/series. These were evaluated for i) fulfilled dependence criteria according to ICD-10, ii) non-medical self administration and their duration, iii) relapses, iv) social sequels, and v) cases seeking treatment for misusing gabapentin or pregabalin. Mostly, the cases of abuse of and dependence on gabapentinoids appeared to be associated with other substance dependencies, primarily opiate dependence and polyvalent drug use. Drug users preferred pregabalin citing a faster and stronger euphoria ("liking") than achievable with oral gabapentin. Both gabapentinoids were anxiolytic in therapeutic doses, stimulating in lower and sedating along with increasing doses. Fatalities have been described mainly in the population of opiate dependents and polyvalent drug users, predominantly together with excessive pregabalin overdosing. It is debated whether the gabapentinoids were indeed the main cause of death in these cases or whether gabapentin and pregabalin had been only bystanders. Tolerance and withdrawal symptoms (physical dependence) of gabapentinoids appeared to be common in medical and non-medical use of gabapentinoids. There were only 4 persons who had fulfilled behavioral dependence criteria of gabapentinoids (all had used pregabalin) and had no association with other substance use disorders (apart from nicotine). Regarding the transitions from prescription to non-medical self-administration, the frequency and duration of self-administrations as well as the number of reported relapses, pregabalin appeared also to be more addictive than gabapentin. However, all these events were reported rather infrequently compared with traditional substances of abuse. We did not find a case with social sequalea due to the use of gabapentinoids or a person who sought treatment for his gabapentin or pregabalin use. Therefore, the gabapentinoids were assumed to possess a lower "wanting" in consideration of Berridge's and Robinsons's incentive-sensitization theory of addiction. Also, anti-adverse selection of gabapentinoids is discussed to be present in the population of opioid and multi-drug users. Based upon all these results and assumptions, we have estimated the relative risk of dependence on gabapentinoids by using an algorithm which was previously developed by Griffith and Johnson for evaluation of the abuse liabilities of sedatives. Overall, the risk of harm and dependence on gabapentinoids appeared to be lower than that of other sedatives (and stimulants). In addition, pregabalin appeared to be somewhat riskier than gabapentin. We think that in patients with current or past substance use disorders, the treatment with gabapentinoids should be avoided or if indispensable, these drugs should be administered exclusively over a limited time span with caution by using a therapeutic and prescription monitoring. PMID- 29179228 TI - Can We Rely on AGNP Therapeutic Targets Also For LAI Antipsychotics? AB - The updated AGNP Consensus Guidelines for Therapeutic Drug Monitoring (TDM) in Neuropsychopharmacology recently published in the journal have reinforced the key role of TDM to individualize psychoparmacological therapies in clinical practice. However, we believe, that these guidelines have missed the important opportunity to face with, and to provide useful information on, the emerging issue of long acting injectable formulations of atypical antipsychotics. Specific therapeutic ranges also for these formulations should be included in the next AGNP guidelines. PMID- 29179229 TI - Learning curve and competence for volumetric laser endomicroscopy in Barrett's esophagus using cumulative sum analysis. AB - BACKGROUND AND STUDY AIMS: Little is known about the learning curve for image interpretation in volumetric laser endomicroscopy (VLE) in Barrett's esophagus (BE). The goal of this study was to calculate the learning curve, competence of image interpretation, sensitivity, specificity, and accuracy of VLE among novice users. METHODS: 31 novice users viewed 96 VLE images electronically at three academic institutions after a brief training session. There were 24 images of each histologic type: normal gastric cardia, normal esophageal squamous epithelium, non-neoplastic BE, and neoplastic BE. The users were asked to identify the correct tissue type and level of confidence. The cumulative summation (CUSUM) technique was used to construct a learning curve. RESULTS: 22 (71 %) of the physicians achieved VLE interpretation competency during their 96 slide review. Half of the physicians achieved competency at 65 images (95 % confidence interval [CI] 45 - 85). There was a statistically significant association between confidence in diagnosis and selecting the correct histologic tissue type (P < 0.001). The median accuracy for esophageal squamous epithelium, normal gastric cardia, non-neoplastic BE, and neoplastic BE was 96 % (95 %CI 95 % - 96 %), 95 % (95 %CI 94 % - 96 %), 90 % (95 %CI 88 % - 91 %), 96 % (95 %CI 95 % 96 %). The overall accuracy was 95 % (95 %CI 93 % - 95 %). CONCLUSION: The majority of novice users achieved competence in image interpretation of VLE for BE, using a pre-selected image set, with a favorable learning curve after a brief training session. An electronic review of VLE images, prior to real-time use of VLE, is encouraged. PMID- 29179230 TI - Endoscopic subtypes of colorectal laterally spreading tumors (LSTs) and the risk of submucosal invasion: a meta-analysis. AB - BACKGROUND AND STUDY AIMS: Many studies have reported on laterally spreading tumors (LSTs), but systematic reviews of the data to determine their risk of containing submucosal invasion (SMI) are lacking. We systematically screened and analyzed the available literature to provide a more solid basis for evidence based treatment. METHODS: We conducted a systematic search in PubMed, Embase, the Cochrane Library, and Scopus for published articles until July 2017. We estimated pooled prevalence or odds ratios (ORs) with 95 % confidence intervals (CIs), using random-effects models. We classified endoscopic subtypes into granular LST, which comprises the homogeneous and nodular mixed subtypes, and non-granular LST, which comprises the flat elevated and pseudodepressed subtypes. RESULTS: We identified 2949 studies, of which 48 were included. Overall, 8.5 % (95 %CI 6.5 % 10.5 %) of LSTs contained SMI. The risk of SMI differed among the LST subtypes: 31.6 % in non-granular pseudodepressed LSTs (95 %CI 19.8 % - 43.4 %), 10.5 % in granular nodular mixed LSTs (95 %CI 5.9 % - 15.1 %), 4.9 % in non-granular flat elevated LSTs (95 %CI 2.1 % - 7.8 %), and 0.5 % in granular homogenous LSTs (95 %CI 0.1 % - 1.0 %). SMI was more common in distally rather than in proximally located LSTs (OR 2.50, 95 %CI 1.24 - 5.02). The proportion of SMI increased with lesion size (10 - 19 mm, 4.6 %; 20 - 29 mm, 9.2 %; >= 30 mm, 16.5 %). The pooled prevalence of patients with one or more LSTs in the general colonoscopy population was 0.8 % (95 %CI 0.6 % - 1.1 %). CONCLUSION: The majority of LSTs are non-invasive at the time of colonoscopic detection and can be treated with (piecemeal) endoscopic mucosal resection. Pretreatment diagnosis of endoscopic subtype, specifying areas of concern (nodule or depression), determines those LSTs at highest risk of containing SMI, where en bloc resection is the preferred therapy. PMID- 29179231 TI - 4H Leukodystrophy: Lessons from 3T Imaging. AB - 4H leukodystrophy is characterized by hypomyelination, hypodontia, and hypogonadotropic hypogonadism. With its variability in clinical symptoms, application of pattern recognition to identify specific magnetic resonance imaging (MRI) features proved useful for the diagnosis. We collected 3T MR imaging data of 12 patients with mutations in POLR3A (n = 8), POLR3B (n = 3), and POLR1C (n = 1), all obtained at the same scanner. We assessed these images and compared them with previously obtained 1.5T images in 8 patients. Novel MRI findings were myelin islets, closed eye sign, and a cyst-like lesion in the splenium. Myelin islets were variable numbers of small T1 hyperintense and T2 hypointense dots, mostly in the frontal and parietal white matter, and present in all patients. This interpretation was supported with perivascular staining of myelin protein in the hypomyelinated white matter of a deceased 4H patient. All patients had better myelination of the medial lemniscus with a relatively hypointense signal of this structure on axial T2-weighted (T2W) images ("closed eye sign"). Five patients had a small cyst-like lesion in the splenium. In 10 patients with sagittal T2W images, we also found spinal cord hypomyelination. In conclusion, imaging at 3T identified additional features in 4H leukodystrophy, aiding the MRI diagnosis of this entity. PMID- 29179232 TI - Differentially Regulated Cell-Free MicroRNAs in the Plasma of Friedreich's Ataxia Patients and Their Association with Disease Pathology. AB - Friedreich's ataxia (FRDA) is a multisystem disease affecting the predominately nervous system, followed by muscle, heart, and pancreas. Current research focused on therapeutic interventions aimed at molecular amelioration, but there are no reliable noninvasive signatures available to understand disease pathogenesis. The present study investigates the alterations of plasma cell-free microRNAs (miRNAs) in FRDA patients and attempts to find the significance in relevance with the pathogenesis. Total RNA from the plasma of patients and healthy controls were subjected to miRNA microarray analysis using Agilent Technologies microarray platform. Differentially regulated miRNAs were validated by SYBR-green real-time polymerase chain reaction (Thermo Fisher Scientific). The study identified 20 deregulated miRNAs (false discovery rate < 0.01, fold change >= 2.0 <=) in comparison with healthy controls; out of which 17 miRNAs were upregulated, and 3 miRNAs were downregulated. Target and pathway analysis of these miRNAs have shown association with neurodegenerative and other clinical features in FRDA. Further validation (n = 21) identified a set of significant (p < 0.05) deregulated miRNAs; hsa-miR-15a-5p, hsa-miR-26a-5p, hsa-miR-29a-3p, hsa-miR-223-3p, hsa-24 3p, and hsa-miR-21-5p in comparison with healthy controls. These miRNAs were reported to influence various pathological features associated with FRDA. The present study is expected to aid in the understanding of disease pathogenesis. PMID- 29179233 TI - A Systematic Review of the Efficacy of Levetiracetam in Neonatal Seizures. AB - OBJECTIVE: Seizures are the most common neurological complication in neonatal intensive care units. Phenobarbital (PB) remains the first-line antiepileptic drug (AED) for neonatal seizures despite known neurotoxicity. Levetiracetam (LEV) is a newer AED not approved for neonates. Retrospective and pilot studies have investigated the use of LEV in neonatal seizures. Our objective was to compare the efficacy of LEV to PB in neonatal seizures based upon published data. METHODS: We searched PubMed to perform a systematic review. We found no studies of LEV with comparison or control groups; therefore, we utilized data from two randomized controlled trials of PB as our comparison group. RESULTS: Five studies of LEV met all inclusion/exclusion criteria. The pooled sample size for LEV was 102 (48 received primary LEV, 54 received secondary LEV). The pooled sample size for primary PB was 52. Complete or near-complete seizure cessation was achieved as follows: primary LEV 37/48 (77%), secondary LEV 34/54 (63%), and primary PB 24/52 (46%). CONCLUSION: Our findings suggest that LEV may be at least as or more effective for neonatal seizures as PB. Our review, though limited, is the first to examine LEV efficacy compared with PB in neonates. PMID- 29179234 TI - Mild Encephalitis/Encephalopathy with Reversible Splenial Lesion (MERS) due to Cytomegalovirus: Case Report and Review of the Literature. AB - Mild encephalopathy with a reversible splenial lesion (MERS) is a clinico radiological syndrome characterized by a transient mild encephalopathy and MRI findings of a reversible lesion in the splenium of corpus callosum (SCC). It is classified in MERS type I and MERS type II, depending on the involvement of SCC alone or also other white matter areas. The syndrome mainly affects children and young adults; the prognosis is favorable with complete or nearly complete neurological and radiological resolution within days or weeks. The vast majority of the cases described in the literature involve Asian and Australian children. The exact pathophysiology is unknown; however, infectious-related MERS (in particular virus associated MERS) remains the most common cause of reversible splenial lesions in childhood. To the best of our knowledge, there is only one published case of MERS associated with cytomegalovirus (CMV) infection involving an Australian child. We present here the first case of a CMV-related MERS in a European Caucasian child. PMID- 29179235 TI - Atypical Neurologic Phenotype and Novel SLC30A10 Mutation in Two Brothers with Hereditary Hypermanganesemia. AB - Manganese (Mn) is an essential element in trace quantity but large amounts are toxic. A novel hereditary disorder encompassing high blood Mn levels, dystonia, polycythemia, distinctive T1 hyperintense signals in the basal ganglia on magnetic resonance imaging (MRI) brain, and chronic liver disease was recently described. The disorder is caused by mutations in a Mn transporter encoding gene SLC30A10. We are reporting the clinical features of this rare disorder in two Saudi brothers. The older brother presented with progressive gait difficulties, hypotonia, intermittent dystonia, polycythemia, and characteristic T1 hyperintense lesions on MRI brain. SLC30A10 sequencing identified a novel missense mutation. The younger brother was identified in presymptomatic phase on family screening. Chelation therapy with disodium calcium edetate (ethylenediaminetetraacetic acid, EDTA) led to stabilization of gait, reduction in Mn levels, and resolution of polycythemia. We wish to highlight the atypical neurologic presentation, a novel missense mutation, and beneficial effect of EDTA in this rare disease.

PMID- 29179237 TI - Older Age and Longer Epilepsy Duration Do Not Predict Worse Seizure Reduction Outcome after Vagus Nerve Stimulation. AB - INTRODUCTION: We analyzed the results of vagus nerve stimulation (VNS) on older patients and patients with long-lasting epilepsy and included severely intellectually disabled patients. PATIENTS AND METHODS: A total of 103 adults with VNS implanted from 2005 to 2014 were studied. The responder rates, that is, the percentage of VNS patients who responded to VNS, classified as seizure reduction >= 50% (50R) and seizure reduction >= 90% (90R), were compared in defined age groups (< 40 and >= 40 years, and < 50 and >= 50 years) and epilepsy duration groups (< 20 and >= 20 years, < 30 and >= 30 years, and < 40 and >= 40 years) at the 1-year follow-up visit and the last follow-up visit (at least 2 years after surgery). The age distributions and responder rates were also studied in patients with an intellectual disability. RESULTS: The analysis did not confirm a significantly lower 50R or 90R rate in patients >= 40, >= 50, or >= 60 years when compared with their younger counterparts, but the 50R rate increase during follow-up care was the lowest in patients >= 50 and >= 60 years. The highest percentage of patients with an intellectual disability in the group < 40 years of age did not adversely affect the 50R rate. Longer epilepsy duration was not confirmed as a negative predictor of VNS outcome. There was a significantly higher 50R rate in patients with epilepsy duration >= 20 years (at the last follow-up visit) and a higher 90R rate in patients with epilepsy duration >= 30 years (at the 1-year follow-up visit). The increase in the 50R rate during follow up care was lower in patients with epilepsy durations >= 30 and >= 40 years. CONCLUSIONS: The study did not find worse VNS outcomes, as defined by the 50R or 90R rate, in older adult patients or in patients with a longer epilepsy duration. The increasing stimulation effect over time is less marked in older patients and in patients with longer epilepsy duration. PMID- 29179238 TI - Modic Type 1 Changes: Detection Performance of Fat-Suppressed Fluid-Sensitive MRI Sequences. AB - PURPOSE: To assess the performance of fat-suppressed fluid-sensitive MRI sequences compared to T1-weighted (T1w) / T2w sequences for the detection of Modic 1 end-plate changes on lumbar spine MRI. MATERIALS AND METHODS: Sagittal T1w, T2w, and fat-suppressed fluid-sensitive MRI images of 100 consecutive patients (consequently 500 vertebral segments; 52 female, mean age 74 +/- 7.4 years; 48 male, mean age 71 +/- 6.3 years) were retrospectively evaluated. We recorded the presence (yes/no) and extension (i. e., Likert-scale of height, volume, and end-plate extension) of Modic I changes in T1w/T2w sequences and compared the results to fat-suppressed fluid-sensitive sequences (McNemar/Wilcoxon-signed-rank test). RESULTS: Fat-suppressed fluid-sensitive sequences revealed significantly more Modic I changes compared to T1w/T2w sequences (156 vs. 93 segments, respectively; p < 0.001). The extension of Modic I changes in fat-suppressed fluid-sensitive sequences was significantly larger compared to T1w/T2w sequences (height: 2.53 +/- 0.82 vs. 2.27 +/- 0.79, volume: 2.35 +/- 0.76 vs. 2.1 +/- 0.65, end-plate: 2.46 +/- 0.76 vs. 2.19 +/- 0.81), (p < 0.05). Modic I changes that were only visible in fat-suppressed fluid-sensitive sequences but not in T1w/T2w sequences were significantly smaller compared to Modic I changes that were also visible in T1w/T2w sequences (p < 0.05). CONCLUSION: In conclusion, fat-suppressed fluid-sensitive MRI sequences revealed significantly more Modic I end-plate changes and demonstrated a greater extent compared to standard T1w/T2w imaging. KEY POINTS: . When the Modic classification was defined in 1988, T2w sequences were heavily T2-weighted and thus virtually fat-suppressed.. . Nowadays, the bright fat signal in T2w images masks edema-like changes.. . The conventional definition of Modic I changes is not fully applicable anymore.. . Fat-suppressed fluid-sensitive MRI sequences revealed more/greater extent of Modic I changes.. CITATION FORMAT: . Finkenstaedt T, Del Grande F, Bolog N et al.

PMID- 29179240 TI - Assessment of Length of Maternal Cervix between 18 and 24 weeks of Gestation in a Low-Risk Brazilian Population. AB - Purpose To determine cervical biometry in pregnant women between 18 and 24 weeks of gestation and the ideal mode of measurement of cervical length in cases of curved and straight cervical morphology. Methods The uterine cervices of 752 low risk pregnant women were assessed using transvaginal ultrasound in a prospective cross-sectional study. In women with straight uterine cervices, cervical biometry was performed in a continuous manner. In women with curved uterine cervices, the biometry was performed using both the continuous and segmented techniques (in segments joining the cervical os). Polynomial regression models were created to assess the correlation between the cervical length and gestational age. The paired Student t-test was used to compare measuring techniques. Results The cervical biometry results did not vary significantly with the gestational age and were best represented by linear regression (R2 = 0.0075 with the continuous technique, and R2 = 0.0017 with the segmented technique). Up to the 21st week of gestation, there was a predominance of curved uterine cervix morphology (58.9%), whereas the straight morphology predominated after this gestational age (54.2%). There was a significant difference between the continuous and the segmented measuring methods in all the assessed gestational ages (p < 0.001). Conclusion Cervical biometry in pregnant women between 18 and 24 weeks was represented by a linear regression, independently of the measuring mode. The ideal measuring technique was the transvaginal ultrasound performed at a gestational age >=21 weeks.

PMID- 29179241 TI - Mandibular Inferior Cortex Erosion on Dental Panoramic Radiograph as a Sign of Low Bone Mineral Density in Postmenopausal Women. AB - Objective To examine the role of the panoramic mandibular radiograph in the diagnosis of low bone mineral density (BMD) in postmenopausal women. Methods A cross-sectional study including volunteer women aged over 40 years in amenorrhea due to ovarian failure for at least 12 months, who were cared for at the climacteric outpatient clinic of a university hospital in the city of Cuiaba, in the state of Mato Grosso, Brazil. The panoramic radiographs were evaluated using a specific software. Two aspects were analyzed in the mandibular panoramic radiograph: a qualitative aspect regarding the shape of the mandibular cortical bone, and a quantitative aspect regarding the width of the mandibular cortical bone. The morphology of the mandibular cortical bone in the digital panoramic radiograph was determined bilaterally by the observation of the bone structure between the mental foramen and the base of the jaw. The mandibular cortical bone was categorized into three groups. The mental index (MI) was used to evaluate the thickness of the mandibular cortical bone through a perpendicular line drawn from the base of the mandible at the height of the center of the mental foramen, with another line drawn tangent to the inferior border of the mandible, and a third line parallel to the line at the superior border of the mandible. The MI data are expressed in millimeters, with a normal value of 3.0 mm. The densities of the lumbar spine and femur, expressed in g/cm2, were categorized as normal, osteopenia or osteoporosis. Results The agreement index between the MI and the BMD of the lumbar spine was good (Kappa = 0.718), but the same index between the MI and the BMD of the femoral neck was poor (Kappa = 0.443). An excellent agreement occurred when the mandibular cortical index (MCI) was compared with the BMD of the lumbar spine (Kappa = 0.912). The agreement between MCI and the BMD in the femur was moderated (Kappa = 0.579). Conclusion The radiomorphometric indices evaluated in the mandibular panoramic radiograph are capable of identifying postmenopausal women with low mineral density in the mandible, and the results can be used to refer these women to appropriate medical investigation and/or treatment. PMID- 29179243 TI - Pyelonephritis in Pregnancy: Clinical and Laboratorial Aspects and Perinatal Results. AB - Objective To identify the prevalence of pyelonephritis during pregnancy and to analyze the clinical and laboratorial aspects, perinatal results and complications. Methods A transversal study of 203 pregnant women who had pyelonephritis during pregnancy and whose labor took place between 2010 and 2016 at a hospital in the state of Santa Catarina, Brazil. The analysis was based on medical records as well as on the hospital's database. Clinical and laboratory conditions, antibiotics, bacterial resistance, perinatal outcomes and complications were all taken into account. The data was compared using the Mann Whitney test and the Chi-square test. Results A prevalence of 1.97% with pyelonephritis was evidenced, with most patients having it during the second trimester of gestation. The bacteria most commonly found in the urine cultures was Escherichia coli, in 76.6% of cases, followed by Klebsiella pneumoniae (8.7%). Ceftriaxone had the lowest bacterial resistance (only 3.5% of the cases). On the other hand, ampicillin and cephalothin presented higher bacterial resistance, 52% and 36.2%, respectively. The risk of very premature delivery was more than 50% higher in patients with pyelonephritis. Conclusion Ampicillin and first-generation cephalosporins are associated with a higher bacterial resistance while ceftriaxone proved to have a high efficacy for the treatment of pyelonephritis due to low bacterial resistance. Patients with pyelonephritis showed a higher risk for very premature delivery (< 32 weeks). In this casuistry, there were no others significant differences in the overall perinatal outcomes when compared with the routine service series. PMID- 29179244 TI - Is Ovarian Cancer Prevention Currently Still a recommendation of Our Grandparents? AB - Ovarian cancer is the leading cause of death among gynecologic tumors because in most of the cases (75%), the disease is diagnosed in advanced stages. Screening methods are not available since the disease is rare, and the tested methods, such as ultrasound and CA125, were not able to decrease the mortality rate for this type of cancer. This article discusses the main risk factors for ovarian cancer, and the potential clinical and surgical strategies for the prevention of this disease. PMID- 29179242 TI - Distance Education Course about Sexuality for Obstetrics and Gynecology Residents. AB - Purpose To describe the experience of a distance education course on sexual issues during pregnancy and after birth for residents. Methods This prospective educational intervention study was conducted by investigators from the Universidade Federal de Sao Paulo, Brazil, between April and September 2014. The participants were 219 physicians (residents from the 1st to the 6th years). The duration of the course was of 24 hours (10 video lectures and online chats). At baseline, the participants answered questions about their training, attitude and experience regarding sexual issues during pregnancy and after birth; before and after the course, they answered questions to assess their knowledge about the topic; at the end of the course, they answered questions on the quality of the course. The Student t-test was used to compare the before and after scores of the knowledge tests; values of p < 0.05 were considered statistically significant. Results A total of 143 residents concluded the course; most were in their 1st (27.2%) or 3rd (29.4%) years of residency. There was a significant increase in the mean scores of the questionnaires that assessed the knowledge of the topic: 4.4 (+/-1.6) versus 6.0 (+/-1.3; maximum score: 10), before and after the course respectively (p < 0.0001). Most of the participants (74.1%) declared that the quality of the course as a whole reached their expectations, and 81.1% would recommend the course to a friend. Conclusions The online Sexology course for Obstetrics and Gynecology residents increased their knowledge about the sexual issues during pregnancy and after birth, and fulfilled the participants' expectations. The experience described here may serve as a model for other sexuality courses targeting similar audiences. PMID- 29179245 TI - Anti-inflammatory Effects of Canthin-6-one Alkaloids from Ailanthus altissima. AB - Canthin-6-one (CO) alkaloids possess various biological activities, including antibacterial, antitumor, antifungal, and antiviral activities. However, their anti-inflammatory effects and underlying molecular mechanisms are poorly characterized. This study aimed to investigate the anti-inflammatory effects of CO and its derivative 5-(1-hydroxyethyl)-canthin-6-one (5-HCO), isolated from the stem barks of Ailanthus altissima in lipopolysaccharide (LPS)-stimulated macrophages. CO (1 and 5 uM) and 5-HCO (7.5 and 15 uM) significantly inhibited the LPS-induced expression of inducible nitric oxide synthase. In addition, CO (1 and 5 uM) and 5-HCO (15 uM) markedly suppressed the production of prostaglandin E2 (PGE2) and expression of cyclooxygenase-2, a key enzyme in PGE2 synthesis, in LPS-stimulated macrophages. Moreover, CO treatment significantly reduced monocyte chemotactic protein-1 (MCP-1) and tumor necrosis factor-alpha (TNF-alpha) expression, whereas 5-HCO inhibited MCP-1, but not TNF-alpha expression. Both CO and 5-HCO inhibited the phosphorylation of inhibitor kappa B and transcriptional activation of nuclear factor kappa B (NF-kappaB) in LPS-stimulated macrophages. In addition, CO, but not 5-HCO, markedly reduced Akt phosphorylation. Taken together, these data suggest that CO, but not 5-HCO with a hydroxyethyl moiety on the D ring, has potent anti-inflammatory activity in LPS-stimulated macrophages through the downregulation of both the NF-kappaB and the Akt pathway. PMID- 29179247 TI - The Developing Role of Anti-Epidermal Growth Factor Receptor Agents in the Treatment of Advanced or Metastatic Colorectal Cancer. AB - The first studies of epidermal growth factor receptor (EGFR) inhibitors in metastatic colorectal cancer were begun before the predictive role of RAS mutations had been elucidated. Secondary analyses of many large randomized trials have shown that mutations in exons 2-4 of KRAS and NRAS, BRAF V600E mutation, and right-sided primary tumor all predict lack of response to EGFR inhibition in the first-line setting. However, even in patient populations defined by a lack of these negative predictors, there is still not uniform response to anti-EGFR therapy. Additionally, although older adults have been shown to have the potential to both tolerate and respond to anti-EGFR therapy, the criteria for selecting the most appropriate older patients for treatment remain unclear. PMID- 29179248 TI - Radical Prostatectomy for Patients With Oligometastatic Prostate Cancer. AB - Cancer progresses in a stepwise fashion. Oligometastatic cancer is an intermediate stage of tumor spread between localized disease and disseminated metastases. Oligometastatic prostate cancer is defined as up to five extrapelvic lesions on conventional imaging. There are controversies surrounding the management of this malignancy, but retrospective and population-based studies suggest a role for radical prostatectomy. Despite insufficient data to draw conclusions regarding the effectiveness of aggressive therapies on overall or cancer-specific survival of patients with oligometastatic prostate cancer, current studies suggest that surgery decreases tumor burden, disease-related morbidity, and the need for palliative surgical intervention, while increasing the period of time to development of castration-resistant disease. PMID- 29179249 TI - Judy Garber on PARP Inhibitors for Triple-Negative Breast Cancer. PMID- 29179250 TI - PI3K Inhibitors: Understanding Toxicity Mechanisms and Management. AB - The phosphatidylinositol 3-kinase (PI3K) pathway has attracted immense interest as a therapeutic target for cancer treatment. Idelalisib was the first PI3K inhibitor approved by the US Food and Drug Administration and is utilized in the treatment of relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma and follicular lymphoma. Copanlisib has subsequently been approved for relapsed follicular lymphoma in patients who have received at least two prior systemic therapies. There are multiple other PI3K agents currently in development; these target various combinations of PI3K isoforms. Despite the therapeutic benefit, there have been concerns about the severe and sometimes fatal adverse effects of this class of drug. Several side effects are unusual and have poorly understood mechanisms; these include autoimmune dysfunction, opportunistic infections, skin toxicity, hypertension, and hyperglycemia. An understanding of these unusual toxicities, as well as a good grasp of management principles, will be important as more PI3K inhibitors are approved and become incorporated into routine practice.

AB - Mucosal melanoma is a rare disease that is distinct from melanomas arising at other sites in the body. While melanocytes are most abundant in the skin, they can be found in smaller numbers in the mucous membranes, as well as in the eye. There are epidemiologic, genetic, and other physiologic differences between melanomas arising from melanocytes at these various sites, and these differences have important implications for both disease prognosis and treatment. Here, we review the features of mucosal melanoma that distinguish it from melanomas arising at other sites, and we highlight recent biological discoveries and emerging treatment options for this aggressive disease. PMID- 29179254 TI - The structure of DLP12 endolysin exhibiting alternate loop conformation and comparative analysis with other endolysins. AB - The lytic enzyme, endolysin, is encoded by bacteriophages (phages) to destroy the peptidoglycan layer of host bacterial cells. The release of phage progenies to start the new infection cycle is dependent on the cell lysis event. Endolysin encoded by DLP12 cryptic prophage is a SAR endolysin which is retained by the bacterium presumably due to the benefit it confers. The structure of DLP12 endolysin (Id: 4ZPU) determined at 2.4 A resolution is presented here. The DLP12 endolysin structure shows a modular nature and is organized into distinct structural regions. One of the monomers has the loops at the active site in a different conformation. This has led to a suggestion of depicting possibly active and inactive state of DLP12 endolysin. Comparison of DLP12 endolysin structure and sequence with those of related endolysins shows the core three-dimensional fold is similar and the catalytic triad geometry is highly conserved despite the sequence differences. Features essential for T4 lysozyme structure and function such as the distance between catalytic groups, salt bridge and presence of nucleophilic water are conserved in DLP12 endolysin and other endolysins analyzed. PMID- 29179255 TI - Excess overdose mortality immediately following transfer of patients and their care as well as after cessation of opioid substitution therapy. AB - AIMS: To investigate clustering of all-cause and overdose deaths after a transfer of patients and their care to alternative treatment provider and after the end of opioid substitution therapy (OST) in opioid-dependent individuals in specialist addiction treatment. DESIGN, SETTING AND PARTICIPANTS: Mortality data were identified within a sample of 5335 patients with opioid use disorder who had received OST treatment between 1 April 2008 and 31 December 2013 from a large mental health-care provider in the United Kingdom. We investigated the circumstances and distribution of the 332 deaths identified within the observation window with a specific focus on overdose deaths (n = 103) after a planned discharge, dropout and transfer between services. MEASUREMENTS: Crude mortality rates for overdose mortality 14 days, 28 days and more than 1 month after the end of treatment/transfer for overdose mortality. FINDINGS: Of 47 individuals who died from overdose after having been transferred between services, nine died during the first 2 weeks [crude mortality rate (CMR) = 136.4, 95% confidence interval (CI) = 64.3-243.1] and a further five died during the first month post-transfer (CMR= 79.5, 95% CI = 44.2-129.7). Of the 32 individuals who died from overdose after planned OST cessation, five died during the first 2 weeks (CMR = 151.5, 95% CI = 51.1-319.0) and a further four died during the first month post-discharge (CMR = 82.6, 95% CI = 38.4-151.0). CONCLUSIONS: In the United Kingdom, opioid-dependent people who are transferred to an alternative treatment provider for continuation of their opioid substitution therapy experience high overdose mortality rates, with substantially higher rates during the first month (especially during the first 14 days) following transfer. PMID- 29179256 TI - SYNJ1 gene associated with neonatal onset of neurodegenerative disorder and intractable seizure. AB - BACKGROUND: Synaptojanin 1 is encoded by the SYNJ1(MIM 604297) and plays a major role in phosphorylation and recycling of synaptic vesicles. Mutation of SYNJ1 is associated with two distinct phenotypes; a known homozygous missense mutation (p.Arg258Gln) associated with early-onset Parkinson disease (MIM 615530), whereas mutation with complete loss of SYNJ1 function result in a lethal neurodegenerative disease with intractable seizure and tauopathies (MIM 617389). METHODS: We report two related children from consanguineous family presented with intractable seizure, profound developmental delay, failure to thrive, acquired microcephaly, and hypotonia. The brain MRI is normal and EEG showed hypsarrhythmia. RESULT: The diagnosis was achieved via whole-genome sequencing which showed homozygous mutation in SYNJ1 (c.709C>T, p.Gln237*). CONCLUSION: A clinical pattern of neonatal-onset intractable seizure, profound developmental delay, muscular hypotonia, hypsarrhythmia, and no focal abnormality of brain MRI should prompt initiation of molecular genetic analysis of SYNJ1. Establishment of the diagnosis permits genetic counseling, prevents patients undergoing unhelpful diagnostic procedures and allows for accurate prognosis. PMID- 29179257 TI - Is the FSHR 2039A>G variant associated with susceptibility to testicular germ cell cancer? AB - Testicular germ cell cancer (TGCC) is derived from germ cell neoplasia in situ (GCNIS), which arises due to niche disturbances affecting the Sertoli cells. It is believed that exogenous endocrine factors have a crucial role in governing neoplastic transformation but on a strong hereditary background. Follicle stimulating hormone (FSH) is the major regulatory hormone of the Sertoli cells. FSH signalling-related single-nucleotide polymorphisms (SNPs) have previously been shown to affect FSH action in men at different levels. We aimed to investigate whether three FSH-related SNPs (FSHR 2039A>G, FSHR -29G>A and FSHB 211G>T) are associated with development of TGCC. A total of 752 Danish and German patients with TGCC from two tertiary andrological referral centres were included. Three control groups comprising 2020 men from the general population, 679 fertile men and 417 infertile men, were also included. Chi-squared test was performed to compare genotype- and allele frequencies. Kruskal-Wallis test was performed to compare age at diagnosis. Patients with TGCC had a higher frequency of the A allele of FSHR 2039A>G compared to the group of fertile men with an AA-genotype frequency of 30.2% vs. 22.0%, respectively, p = 0.002. This variant is associated with higher FSH receptor activity. The distribution of the FSHR 2039A>G did not differ significantly between the patients with TGCC and the infertile or the general population. The frequency of the two other SNPs did not differ between patient with TGCC and any of the control groups. No differences were detected between genotypes and age distribution or histological subtype of the tumours. In conclusion, we observed that a genetic variant associated with FSHR activity may modulate the susceptibility to TGCC. PMID- 29179258 TI - Increased risk of autoimmune disorders in infertile men: analysis of US claims data. AB - Aberrations in reproductive fitness may be a harbinger of medical diseases in men. Existing data suggest that female infertility is associated with autoimmune disorders; however, this has not been examined in men. As immune surveillance and hormonal factors can impact male fertility and autoimmunity, we sought to determine the association between male infertility and incident autoimmune disorders. We analyzed subjects from the Truven Health MarketScan claims database from 2001 to 2008. Infertile men were identified through diagnosis and treatment codes. We examined the most common immune disorders, which were identified by ICD9 diagnosis codes. Men diagnosed with an immune disorder at baseline or within 1 year of follow-up were excluded. Infertile men were compared to vasectomized men (i.e., men who are likely fertile) and to age-matched control (10 : 1) group using Cox regression analysis. A total of 33,077 infertile men (mean age of 33 years), 77,693 vasectomized men (mean age 35), and 330,770 age-matched control men (mean age 33) were assembled with a total follow-up of 1.49 M person-years. Overall, immune disorders were rare in the group with the individual conditions occurring in <0.1% of men. However, infertile men displayed the highest risk of many conditions. Infertile men had a higher risk of developing rheumatoid arthritis compared to both vasectomized men (HR 1.56, 95% CI 1.19-2.05) and age matched controls (HR 1.29, 95% CI 1.02-1.62). Additionally, this higher risk was seen in general immune disorders (under which systemic lupus erythematosus is categorized) compared to vasectomized men (HR 3.11, 95% CI 2.00-4.86) and age matched men (HR 2.12, 95% CI 1.52-2.96). This same risk trend was seen in psoriasis, when compared to vasectomized men (HR 1.28, 95% CI 1.09-1.50) and age matched controls (HR 1.20, 95% CI 1.04-1.37). A similar trend was seen in the analysis comparing infertile men and vasectomized men in developing multiple sclerosis (HR 1.91, 95% CI 1.10-3.31) and Grave's disease (HR 1.46, 95% CI 1.10 1.92), as well as the higher risk of infertile men compared to the age-matched group at developing thyroiditis (HR 1.60, 95% CI 1.02-2.52). The current analysis shows that infertile men have a higher risk of developing certain autoimmune disorders in the years following an infertility evaluation. Specifically, infertile men had higher rates of developing rheumatoid arthritis, multiple sclerosis, psoriasis, thyroiditis, and Grave's disease. Given these findings, further research should focus on confirmation of these associations and elucidation of the pathways between fertility and immunity. PMID- 29179259 TI - Roles of histone H3.5 in human spermatogenesis and spermatogenic disorders. AB - Histone H3.5 (H3.5) is a newly identified histone variant highly expressed in the human testis. We have reported the crystal structure, instability of the H3.5 nucleosome and accumulation around transcription start sites, mainly in primary spermatocytes, but its role in human spermatogenesis remains poorly understood. Testicular biopsy specimens from 30 men (mean age: 35 years) with non-obstructive azoospermia (NOA) who underwent microdissection testicular sperm extraction and 23 men with obstructive azoospermia (OA) were included. An H3.5-specific mouse monoclonal antibody recognizing an H3.5-specific synthetic peptide was generated, and immunohistological staining for H3.5 and proliferating cell nuclear antigen (PCNA) was performed on Bouin's solution-fixed sections. Expression and localization of H3.5 were compared with patient background, germinal stage, and PCNA expression. In testes of patients with normal spermatogenesis, differentially expressed H3.5 was specifically localized in either spermatogonia or preleptotene/leptotene-stage primary spermatocytes, especially during germinal stages VI-X. In NOA testes, mRNA expression of H3.5 (H3F3C) was significantly reduced compared with other H3 histone family members, and expression of H3.5 was significantly lower than that in OA. Additionally, the number of H3.5-positive germ cells was higher in hypospermatogenesis or late maturation arrest than in early maturation arrest in NOA testes (p < 0.01). A significant positive correlation was observed between H3.5 and PCNA expression (p < 0.05) but not TUNEL-positive cells, and expression of H3.5 was enhanced after hCG-based salvage hormonal therapy. Different from other testis-specific histones, which are often expressed during the histone-to-protamine transition during meiosis, H3.5 was expressed mainly in immature germ cells. H3.5 may play roles in DNA synthesis, but not apoptosis, and its expression is regulated by gonadotropins, indicating that such epigenetic regulations are important in normal spermatogenesis and spermatogenic disorders. PMID- 29179260 TI - Naringenin attenuates highly active antiretroviral therapy-induced sperm DNA fragmentations and testicular toxicity in Sprague-Dawley rats. AB - Highly active antiretroviral therapy has evolved over the years, leading to a boost in the quality of life in people living with HIV and AIDS. However, growing evidence has shown that highly active antiretroviral therapy has deleterious effects on the testes and the overall reproductive capacity. Therefore, this study is to determine the adjuvant potential of Naringenin on highly active antiretroviral therapy-induced perturbations in fertility of male Sprague-Dawley rats. Thirty adult male Sprague-Dawley rats were divided into six groups viz - Control; H: 30 mg/kg of highly active antiretroviral therapy (EFV, 600 mg + FTC, 200 mg + TDF, 300 mg); N40: Naringenin, 40 mg/kg; N80: Naringenin, 80 mg/kg; HN40: highly active antiretroviral therapy + Naringenin, 40 mg/kg; HN80: highly active antiretroviral therapy + Naringenin, 80 mg/kg. The rats were euthanized after 4 weeks. Results showed that there was a significant decrease in sperm count (p < 0.001), spermatozoa with normal morphology (p < 0.001) and progressive sperm motility (p < 0.05) of H compared to the control and the HN groups. Likewise, fragmentations increased (p < 0.05) in tail lengths of sperm DNA in H compared to control. HN40 and HN80 decreased tail lengths compared to H (p < 0.001). There was also a decrease in %tail DNA and tail moment in HN40 (p < 0.001) compared to H. Luteinizing hormone significantly increased (p < 0.05) in HN40, HN80, and N40 (p < 0.001) but decreased in H (p < 0.05) compared to control. The diameter of the seminiferous tubules also decreased (p < 0.05) in H compared to control, N80, and HN40. Likewise, the area of the seminiferous tubules in group H decreased (p < 0.05) compared to N80 and HN80. The seminiferous tubules epithelium increased (p < 0.05) in N40 and HN40 compared to H. This study establishes that highly active antiretroviral therapy has deleterious effects on the testicular microanatomy, sperm parameters, and sperm DNA of Sprague-Dawley rats, which may impair fertility but Naringenin is a potential complimentary adjuvant. PMID- 29179261 TI - Targeted Base Editing via RNA-Guided Cytidine Deaminases in Xenopus laevis Embryos. AB - Genome editing using programmable nucleases such as CRISPR/Cas9 or Cpf1 has emerged as powerful tools for gene knock-out or knock-in in various organisms. While most genetic diseases are caused by point mutations, these genome-editing approaches are inefficient in inducing single-nucleotide substitutions. Recently, Cas9-linked cytidine deaminases, named base editors (BEs), have been shown to convert cytidine to uridine efficiently, leading to targeted single-base pair substitutions in human cells and organisms. Here, we first report on the generation of Xenopus laevis mutants with targeted single-base pair substitutions using this RNA-guided programmable deaminase. Injection of base editor 3 (BE3) ribonucleoprotein targeting the tyrosinase (tyr) gene in early embryos can induce site-specific base conversions with the rates of up to 20.5%, resulting in oculocutaneous albinism phenotypes without off-target mutations. We further test this base-editing system by targeting the tp53 gene with the result that the expected single-base pair substitutions are observed at the target site. Collectively, these data establish that the programmable deaminases are efficient tools for creating targeted point mutations for human disease modeling in Xenopus. PMID- 29179262 TI - Advances towards Controlling Meiotic Recombination for Plant Breeding. AB - Meiotic homologous recombination generates new combinations of preexisting genetic variation and is a crucial process in plant breeding. Within the last decade, our understanding of plant meiotic recombination and genome diversity has advanced considerably. Innovation in DNA sequencing technology has led to the exploration of high-resolution genetic and epigenetic information in plant genomes, which has helped to accelerate plant breeding practices via high throughput genotyping, and linkage and association mapping. In addition, great advances toward understanding the genetic and epigenetic control mechanisms of meiotic recombination have enabled the expansion of breeding programs and the unlocking of genetic diversity that can be used for crop improvement. This review highlights the recent literature on plant meiotic recombination and discusses the translation of this knowledge to the manipulation of meiotic recombination frequency and location with regards to crop plant breeding. PMID- 29179263 TI - Odorant Receptors Containing Conserved Amino Acid Sequences in Transmembrane Domain 7 Display Distinct Expression Patterns in Mammalian Tissues. AB - Mammalian genomes are well established, and highly conserved regions within odorant receptors that are unique from other G-protein coupled receptors have been identified. Numerous functional studies have focused on specific conserved amino acids motifs; however, not all conserved motifs have been sufficiently characterized. Here, we identified a highly conserved 18 amino acid sequence motif within transmembrane domain seven (CAS-TM7) which was identified by aligning odorant receptor sequences. Next, we investigated the expression pattern and distribution of this conserved amino acid motif among a broad range of odorant receptors. To examine the localization of odorant receptor proteins, we used a sequence-specific peptide antibody against CAS-TM7 which is specific to odorant receptors across species. The specificity of this peptide antibody in recognizing odorant receptors has been confirmed in a heterologous in vitro system and a rat-based in vivo system. The CAS-TM7 odorant receptors localized with distinct patterns at each region of the olfactory epithelium; septum, endoturbinate and ectoturbinate. To our great interests, we found that the CAS TM7 odorant receptors are primarily localized to the dorsal region of the olfactory bulb, coinciding with olfactory epithelium-based patterns. Also, these odorant receptors were ectopically expressed in the various non-olfactory tissues in an evolutionary constrained manner between human and rats. This study has characterized the expression patterns of odorant receptors containing particular amino acid motif in transmembrane domain 7, and which led to an intriguing possibility that the conserved motif of odorant receptors can play critical roles in other physiological functions as well as olfaction.

PMID- 29179267 TI - [Significance of p16/Ki-67 double immunocytochemical staining in cervical cytology ASCUS, LSIL, and ASC-H]. AB - Objective: To investigate the application value of p16/cell proliferation associated nuclear antigen (Ki-67) double-staining and human papillomavirus mRNA in the cytological screening. Methods: Two hundred and fifty-one cases who suffered from atypical squamous cell of undetermined significance (ASCUS), low grade squamous intraepithelial lesion (LSIL), atypical squamous cell-cannot exclude high-grade squamous intraepithelial lesion (ASC-H) in ThinPrep cytologic test (TCT) were collected in Peking University First Hospital between October 2015 and March 2016. And p16/Ki-67 double-staining and hybrid capture II (HC-II) detection were performed on the cervical cells. The result was compared with the pathological result of colposcope guided biopsy. All statistical analysis was completed by Stata 12.0 statistical software analysis. The results of diagnostic tests were described by using the sensitivity, specificity, positive predictive value,negative predictive value, and the area under the receiver operating characteristic (ROC) curve. Results: (1) One hundred and eight cases of liquid based cytology diagnosis of ASCUS patients, the positive rate of p16/Ki-67 was 13.9% (15/108), 102 cases of liquid based cytology diagnosis of LSIL patients, the positive rate of p16/Ki-67 was 21.6% (22/102), 41 cases of liquid based cytology diagnosis of ASC-H patients, the positive rate of p16/Ki-67 was 39.0% (16/41), compared amongthree groups, the difference was statistically significant (chi(2)=78.516, P<0.05); cervical exfoliated cells p16/Ki-67 expression rate was 13.0%(28/215) in cervical low-grade lesions [cervical intraepithelial neoplasia (CIN) I], which was 69.4%(25/36) in high level lesions (CIN II-III), the difference was statistically significant (chi(2)=7.932, P<0.05). (2) The specificity of p16/Ki-67 detection and diagnosis were higher than those of HC-II in ASCUS, LSIL, and ASC-H (89.8% vs 71.4%, 83.3% vs 15.6%, 88.9% vs 40.7%; all P<0.05), meanwhile, the positive predictive value of p16/Ki-67 detection and diagnosis exceed those of HC-II in ASCUS, LSIL, and ASC-H (33.3% vs 26.3%, 31.8% vs 12.6%, 81.3% vs 38.5%; all P<0.05). Moreover, the ROC curve of p16/Ki-67 were bigger than those of HC-II in ASCUS, LSIL, and ASC-H (0.799 vs 0.696, 0.708 vs 0.531, 0.909 vs 0.561; all P<0.05). Conclusion: For patients with cytological diagnosis of ASCUS, LSIL, and ASC-H, p16/Ki-67 double staining method could be used as an effective method to assist in the diagnosis of high-grade cervical lesions, and the screening efficiency is superior to that of high-rist HPV. PMID- 29179268 TI - [Natural changes of high-risk HPV in women with negative for intraepithelial lesion or malignancy: a prospective 1 year study]. AB - Objective: To investigate the natural changes of high-risk HPV (HR-HPV) in women with negative for intraepithelial lesion or malignancy (NILM) for regulating HR HPV screening. Methods: Four hundred and thirty-three newly-diagnosed women were enrolled from January 1st, 2015 to December 31, 2015 in Beijing Obstetrics and Gynecology Hospital. The ages of these patients were between 22 and 74 years, the average age was (45+/-21) years old. Two hundred and sixty-three cases were less than 50 years old, 170 cases were more and equal to 50 years old. One hundred and fifty-six cases were HR-HPV positive, 277 cases were HR-HPV negative. Follow up tests were conducted for all 433 patients, who were screened by ThinPrep cytologic test (TCT) combined with HR-HPV and were diagnosed with NILM, for a period of 1 year (at the 3, 6, 9 and 12 months intervals respectively), if the TCT results are abnormal and the HR-HPV test results are positive, will follow up colposcopy directed cervical biopsy. Results: (1) HR-HPV natural changes: of 156 NILM cases with HR-HPV infection, 42 cases (26.9%, 42/156) turned negative within 3 months, 88 cases (56.4%, 88/156) turned negative within 6 months, 99 cases (63.5%, 99/156) turned negative within 9 months, and 100 cases (64.1%, 100/156) turned negative within 12 months. The negative conversion ratio at 3, 6, 9 and 12 months for women at childbearing age (<50 years) were significantly higher than those at non-childbearing age (>=50 years old; all P<0.05). Of 277 NILM cases without HR-HPV infection, 35 cases (12.6%, 35/277) had new HR-HPV positive infections within 3 months, 70 cases (25.3%, 70/277) had new infections within 6 months, 80 cases (28.9%, 80/277) had new infections within 9 months, and 83 cases (30.0%, 83/277) had new infections within 12 months. The new infections rate at 3, 6, 9 and 12 months for women at childbearing age (<50 years old) were slightly higher than those at non-childbearing age (>=50 years old; all P>0.05). (2) The progress of cervical leision: of 156 NILM cases with HR-HPV positive, no case progressed during 12 months follow-up. Of 277 NILM cases with HR-HPV negative, 4 cases progressed to cervical intraepithelial neoplaisa (CIN) with HR-HPV infection and TCT abnormal during 12 months follow-up, including 2 cases pathology diagnosed with CINI, 1 case with CINII, and 1 case with CINIII. The progression rate was 1.4%(4/277), which accounts for 4.8% (4/83) of new HR-HPV infections cases in women. Conclusions: The results of cytology combined with HR HPV screenings suggest every 6 months for simple HR-HPV positive women, colposcopy directed cervical biopsy is recommended to assess cervical lesions if necessary. Cytology combined with HR-HPV screenings suggest every 12 months for simple HR-HPV negative women to early detection of cervical leision. PMID- 29179269 TI - [Study on clinical management of HPV(+)/Pap(-) during cervical cancer screening]. AB - Objective: To study the clinical management way for HPV(+)/papanicolaou (Pap)(-) during cervical cancer screening. Methods: To analyze retrospectively the data from the patients who had loop electrical excision procedure (LEEP) for biopsy confirmed cervical intraepithelial neoplasia (CIN) II in Peking University People's Hospital from Jan. 2010 to Dec. 2014. Results: (1) For biopsy confirmed CIN II, HPV positive rate was 98.5% (135/137), Pap test positive [>=atypical squamous cell of undetermined significance (ASCUS)] rate was 69.3% (95/137), there was significant difference between them (chi(2)=43.32, P<0.01). (2) For the 42 patients with HPV(+)/Pap(-), whose cytology slides were reviewed again. Among them, the interpretations of there were 16 cases confirmed as the same before, while 26 cases were changed to abnormal (>=ASCUS). Cytology be misdiagnosed was 19.0% (26/137) at the first review. Among the 26 cases, 13 (50.0%) cases were missed for the little amount of abnormal cells, 8 (30.8%) cases for mild atypical morphology changed; the other 5 (19.2%) cases missed for stain problems. (3) For the cervical LEEP samples, 37 cases of the pathology diagnosis were upgrade to CIN III(+), among them, 2 cases of microinvasive cervical carcinoma, 1 case of invasive cancer, 34 cases of CIN III; 37 cases were CINI or no lesion found; 63 cases were still CIN II. Four to six months later after LEEP, the cytology abnormal rate was 11.7% (16/137), and the HR-HPV positive rate was 34.3% (47/137). Conclusions: Compared with cytology alone, cytology combined with HPV testing increase the sensitivity of cervical high grade lesion. For the cases of HPV(+)/Pap(-) cases, the cytology slides should be reviewed. The quality control of cervical exfoliate sample collection and interpretation should be strengthened. LEEP procedure is not only a treatment method, but also it could provide samples to confirm the diagnosis. PMID- 29179270 TI - [Clinical outcome and high risk factor for residual lesion analysis of HSIL half a year after loop electrosurgical excision procedure: a clinical study of 1 502 cases]. AB - Objective: To analyze clinical outcome of high-grade squamous intraepithelial lesion (HSIL) half a year after loop electrosurgical excision procedure (LEEP) and explore the high risk factor of residual cervical HSIL. Methods: The retrospective study was carried out on 1 502 patients who underwent LEEP, with HSIL in the LEEP histopathology from January 2011 to December 2013 at Obstetrics and Gynecology Hospital of Fudan University to confer the difference between residual group and non-residual group after 6 months of the leep conization. Patients were followed with ThinPrep cytologic test (TCT), high risk HPV (HR-HPV) test, colposcopy guided biopsy (CBD) and endocervical curettage (ECC). The high risks of residual cervical HSIL was analyzed. Results: Among 1 502 cases, 48 (3.20%, 48/1 502) cases suffered HSIL residual disease. Forty cases were diagnosed by CBD, 4 cases were diagnosed by ECC. The other 4 cases were both positive in CBD and ECC. Residul rate were different among different age groups. The residual rate was higher in the age >=50 years old compared to the age below 50 [9.70% (16/165), 2.39% (32/1 337); chi(2)=25.33, P<0.01]. For post-LEEP specimens, both circumference (2.5, 2.8 cm; Z=-3.17, P<0.01) and width [0.6, 0.6 cm; Z=-2.88, P<0.01) were less in HSIL lesion residual group than those in non residual group, though length showed no obvious difference [1.5, 1.5 cm; Z=-1.55, P>0.05) . The residual rate of leep positive margin was obviously higher than that in the negative margin group [6.77% (18/266) vs 2.43% (30/1 236) ; chi(2)=13.30, P<0.01]. Different positive margin had diverse residual rate, as positive endocervical margin was 16.07% (9/56), positive margin undetermined was 7.29%(7/96) and positive ectocervical margin was 3.33%(4/120). Both positive endocervical margin and positive margin undetermined had a higher residual rate than residual rate (chi(2)=26.99, P<0.01; chi(2)=4.24, P<0.05). Abnormal cytology showed higher residual rate than the non-residual with significant difference [6.00% (6/100) vs 1.29% (14/1 083) , chi(2)=9.50, P<0.01]. In terms of the post LEEP HR-HPV test follow-up, HR-HPV positive's residual rate was higher than that in the negative group [2.91% (6/206) vs 0.96% (7/727)], while there was no statistical significance (chi(2)=3.10, P>0.05). Multivariate logistic analysis showed that abnormal cytology in 6 month's follow-up post-LEEP conization was an independent risk factor on residual lesion (OR=3.75, P<0.05). Conclusions: Patient with age >=50 years old and positive endocervical margin are high risk factors for the residual HSIL lesion after LEEP conization,especially for abnormal cytology during follow up is independent risk factor for residual lesion. Colposcopy directed biopsy and (or) ECC still play an indispendsable role in finding the HSIL residual lesion. PMID- 29179271 TI - [Relationship between the risk of emergency cesarean section for nullipara with the prepregnancy body mass index or gestational weight gain]. AB - Objective: To investigate the risk of emergency cesarean section during labor with the pre-pregnancy body mass index or gestational weight gain. Methods: A total of 6 908 healthy nullipara with singleton pregnancy and cephalic presentation who was in term labor in Beijing Obstetrics and Gynecology Hospital from August 1(st), 2014 to September 30(th), 2015 were recruited. They were divided into two groups, the vaginal delivery group (92.88%, 6 416/6 908) and the emergency cesarean section group (7.12%, 492/6 908). According to WHO body mass index (BMI) classification criteria and the pre-pregnancy BMI, the 6 908 women were divided into three groups, the underweight group(BMI<18.5 kg/m(2); 17.39%, 1 201/6 908), the normal weight group(18.5-24.9 kg/m(2); 73.00%, 5 043/6 908), the overweight and obese group (>= 25.0 kg/m(2); 9.61%, 664/6 908). According to the guidelines of Institute of Medicine (IOM) , they were divided into three groups, the inadequate gestational weight gain (GWG) group (16.72%, 1 155/6 908), the appropriate GWG group (43.11%, 2 978/6 908), the excessive GWG group (40.17%, 2 775/6 908). Unadjusted and adjusted odds ratio (OR) and confidence interval (CI) of the risk of emergency cesarean section were calculated by bivariate logistic regression. Results: (1) Comparing to the vaginal delivery group, women in the emergency cesarean section group were older, with a lower education level. Their prepregnancy BMI was higer and had more gestational weight gain. They had higher morbidity of pregnancy induced hypertension and gestational diabetes mellitus. Comparing to the vaginal delivery group, the neonates in the emergency cesarean section group were elder in gestational week, with higher birth weight. More male infants and large for gestation age infants were seen in the emergency cesarean section group (all P<0.05) . (2) Overweight and obesity were associated with the increased risk of emergency cesarean section for nullipara, with the unadjusted OR of 1.98 (95%CI: 1.54-2.54), adjusted OR (aOR) of 1.66 (95%CI: 1.27-2.16). In the inadequate GWG group and the excessive GWG group, overweight and obese women had increased risk of emergency cesarean section, with adjusted OR of 2.33 (95%CI: 1.06-5.14) and 1.62 (95%CI: 1.44-2.28), respectively. In the appropriate GWG group, there was no significant difference in the risk of emergency cesarean section between the overweight and obese women and the normal weight women, with aOR of 1.54 (95%CI: 0.94-2.54). The underweight group was associated with decreased risk of emergency cesarean section (OR=0.55, 95%CI: 0.40-0.74; aOR=0.66, 95%CI: 0.48-0.90). While no significant difference in the risk of emergency cesarean section was found between the underweight women, the overweight and obese women, with the aOR of 0.31 (95%CI: 0.07-1.32), 0.73 (95%CI: 0.48-1.10), 0.66 (95%CI: 0.38-1.12), respectively. (3) Absolute value of gestational weight gain was associated with the increased risk of emergency cesarean section, (aOR=1.03, 95%CI: 1.01-1.05). GWG above IOM giudelines did not independently affect the risk of emergency cesarean section (OR=1.30, 95%CI: 1.07 1.58; aOR=1.01, 95%CI: 0.82-1.24). In the underweight group, the normal weight group and the overweight or obese group, the excessive GWG women and the appropriate GWG women had no significant difference in the risk of emergency cesarean section (aOR=1.03, 95%CI: 0.55-1.12; aOR=1.02, 95%CI: 0.80-1.30; aOR=1.03, 95%CI: 0.59-1.78) , respectively. GWG below IOM giudelines was associated with decreased risk of emergency cesarean section (OR=0.62, 95%CI: 0.45-0.85; aOR=0.64, 95%CI: 0.46-0.88). In the underweight group and the overweight or obese group, there was no significant difference in the emergency cesarean section risk between the inadequate GWG women and the appropriate GWG within women (aOR= 0.24, 95%CI: 0.06-1.01; aOR= 0.90, 95%CI: 0.40-2.04) . In the normal weight group, the inadequate GWG women had lower risk of emergency cesarean section (aOR=0.65, 95%CI: 0.45-0.95). Conclusions: Overweight and obese women have increased risk of emergency cesarean section. The prepregnancy BMI is supposed to be an appropriate level. Absolute value of gestational weight gain is associated with increased risk of emergency cesarean section. There is no correlation between the excessive GWG and the risk of emergency cesarean section. PMID- 29179272 TI - [Analysis of non-invasive prenatal screening detection in fetal chromosome aneuploidy]. AB - Objective: To evaluate the efficacy of non-invasive prenatal screening (NIPS) in the detection of fetal aneuploidies. Methods: Cell free DNA was sequenced in 5 566 pregnant women to identify the fetal aneuploidies in the First Affiliated Hospital of Zhengzhou University from January 1(st), 2015 to March 15(th), 2016. Among them, 5 230 (93.96%, 5 230/5 566) were singleton pregnancies and 336 (6.04%, 336/5 566) were twin pregnancies. In singleton pregnancies, 1 809 (34.59%, 1 809/5 230) were women with advanced maternal age, and 3 421 (65.41%, 3 421/5 230) were young women. The positive results of NIPS were validated by karyotyping through invasive procedures and neonatal outcomes were followed up by telephone. Results: Among the 5 566 women, 69 (1.24%, 69/5 566) got positive NIPS results, with 66 in singleton pregnancies and 3 in twin pregnancies. Two were monochorionic diamniotic twins and 1 was dichorionic twin pregnancy. The positive predictive value of NIPS for trisomy 21, 18 and 13 were 100.0%, 90.9% and 100.0%, and was 55.6% for sex chromosome aneuploidies. There was no false negative case found during the follow-up. In the advanced maternal age group and young women group, the prevalence rates of fetal chromosomal aneuploidies were 1.11%(20/1 809) and 0.94%(32/3 421), respectively. In the young women with soft markers in fetal ultrasound, the prevalence of fetal chromosomal aneuploidies was 1.44% (7/487), and in serum high risk women, it was 0.94% (7/747). In women with the serum screening risk with cut-off value, 0.89%(9/1 016) had fetal aneuploidies, and the prevalence was 0.77%(9/1 171) in volunteers. There was no statistically significant difference among these groups (P=0.636). Conclusions: There is no difference in the detection rate of fetal aneuploidies between high-risk women in serum screening and volunteers in NIPS. NIPS is more suitable as a first line screening test for women without fetal ultrasound abnormalities. It should be used carefully when there is ultrasound abnormalities.

AB - Objective: To explore the relationship between the embryo with the different morphological types in the third day and its mitochondrial copy number, the membrane potential. Methods: Totally 117 embryos with poor development after normal fertilization and were not suitable transferred in the fresh cycle and 106 frozen embryos that were discarded voluntarily by infertility patients with in vitro fertilization-embryo transfer after successful pregnancy were selected. According to evaluation of international standard in embryos, all cleavage stage embryos were divided into class I frozen embryo group (n=64), class II frozen embryo group (n=42) and class III fresh embryonic group (not transplanted embryos; n=117). Real-time PCR and confocal microscopy methods were used to detect mitochondrial DNA (mtDNA) copy number and the mitochondrial membrane potential of a single embryo. The differences between embryo quality and mtDNA copy number and membrane potential of each group were compared. Results: The copy number of mtDNA and the mitochondrial membrane potential in class III fresh embryonic group [(1.7+/-1.0)*10(5) copy/MUl, 1.56+/-0.32] were significantly lower than those in class I frozen embryo group [(3.4+/-1.7)*10(5) copy/MUl, 2.66+/-0.21] and class II frozen embryo group [(2.6+/-1.2)*10(5) copy/MUl, 1.80+/ 0.32; all P<0.05]. The copy number of mtDNA and the mitochondrial membrane potential in classI frozen embryo group were significantly higher than those in classII frozen embryo group (both P<0.05). Conclusion: The mtDNA copy number and the mitochondrial membrane potential of embryos of the better quality embryo are higher.

AB - Objective: To investigate a novel mutation in the HAND1 gene associated with sporadic dilated cardiomyopathy (DCM). Methods: From February 2013 to February 2017, the clinical data and peripheral venous blood samples were collected from 120 patients with sporadic DCM and 200 healthy controls, who were both from the Fifth People's Hospital of Shanghai, Fudan University and Shanghai Chest Hospital, Shanghai Jiaotong University.The genomic DNA was extracted from the study participants.The coding exons of HAND1 were amplified from the study subjects by polymerase chain reaction, and were sequenced for a potential HAND1 mutation.The online computer programs MUSCLE and Mutation Taster were used to analyze the conversation of an altered amino acid and to predict the disease causing potential of an identified mutation, respectively.The wild-type HAND1 was cloned and the mutant was generated by site-directed mutagenesis.The Dual luciferase reporter assay kits were used to explore the functional characteristics of the mutant HAND1. Results: A novel heterozygous mutation, a substitution of thymine for guanine at nucleotide 346 (c.346G>T), predicting the conversion of a glutamic acid-encoding codon into a stop codon at codon 116 (p.E116X), was detected in a patient with sporadic DCM.The nonsense mutation was absent in the 200 control individuals.The altered glutamic acid at amino acid position 116 was highly conserved evolutionarily, and the mutation was predicted to be pathogenic.Biological analyses revealed that the mutant HAND1 lost the ability to transcriptionally activate a target gene. Conclusion: Loss-of-function mutation in HAND1 is likely to be an uncommon cause responsible for sporadic DCM.

AB - Objective: To observe the clinical effectiveness and safety of ticagrelor in patients after percutaneous coronary intervention (PCI) because of acute non ST segment elevation myocardial infarction (NSTEMI) in China. Methods: A total of 240 patients with NSTEMI were analyzed retrospectively from Beijing Anzhen hospital between Jan 2013 and Jan 2015, with 113 patients in the clopidogrel group, 127 in the ticagrelor group. ADP-induced platelet aggregation was investigated 1, 3 and 6 month later after PCI, and major adverse cardiac events (MACE) and thrombolysis in myocardial infarction (TIMI) bleeding were followed-up for 6 months. Results: ADP-induced platelet aggregations of the ticagrelor group [(29+/-5)%, (29+/-6)%, (26+/-7)%] were decreased significantly compared with the clopidogrel group [(50+/-9)%, (49+/-9)%, (46+/-8)%] 1, 3 and 6 month later after PCI (P<0.01). Compared with the clopidogrel group (17.7%), the incidence of MACE of ticagrelor group (7.09%) was significantly decreased 6 month later after PCI (P<0.05), but there were no statistical differences in the incidence of TIMI major bleeding and secondary hemorrhage between the two groups (P>0.05). Conclusion: Ticagrelor combined with aspirin can decrease the MACE incidence of NSTEMI, and do not increase TIMI major bleeding and secondary hemorrhage. PMID- 29179276 TI - [Analysis of contrast echocardiography for detecting right to left shunt in adults with patent foramen ovale]. AB - Objective: To analyze the contrast echocardiography for detecting right to left shunt in adults with patent foramen ovale(PFO), and study the relationship between PFO and cryptogenic stroke. Methods: Clinical data of forty-six adults patients with PFO diagnosed by transesophageal echocardiography(TEE)from March, 2012 to March, 2017 were retrospectively collected, and the patients were divided to 3 groups according to the direction and brightness of the color Doppler shunts: obvious left-to-right shunt (OLRS, group A), weak left-to-right shunt(WLRS, group B), bi-directional shunt(BDS, group C). A right-to-left shunt (RLS) scale was calculated using the method of 10 ml hand-operated saline for contrast echocardiography. Results: There were seventeen cases in group A, four cases (23.5%) showed RLS at level 1, and thirteen cases (76.5%) showed no RLS; there were twenty cases in group B, and all cases (100%) showed RLS, with five cases (25%) at level 1 and fifteen cases (75%) at level 2-3; there were nine cases in group C, and all cases (100%) showed RLS, with two cases (22.2%) at level 1 and seven cases (77.8%) at level 2-3. Anteroposterior diameter of left atrium of patients with no RLS (4.8 cm+/-0.6 cm) was significantly larger than that of patients with RLS in contrast echocardiography (3.6 cm+/-0.5 cm)(P=0.000). Conclusions: OLRS of adults with patent foramen ovale and with larger left atrium have less RLS than WLRS and DLRS with normal left atrium in contrast echocardiography.The possibility of paradoxical embolism in WLRS and DLRS is higher than that in OLRS, which should be taken seriously in clinical practice.

AB - Objective: To investigate the relationship between the expression of macrophage migration inhibitory factor (MIF) gene and the incidence of gestational diabetes mellitus (GDM) in Chinese Han population in northern China. Method: This study was consisted of 126 GDM women and 150 cases of healthy subjects who came from the obstetrics department of Maternity Hospital of Qingdao University and Maternity and Child Care Hospital of Donggang District of Rizhao. The protein expression of MIF in placenta tissue was detected by Western blot method. The blood glucose, insulin levels and other clinical physicochemical index were tested. The differences of MIF, fasting blood-glucose (FBG), fasting insulin (FIN) and the homeostasis model assessment of insulin resistance (HOMA-IR) were compared between the two groups of pregnant women. Result: The level of MIF protein in GDM group (0.85+/-0.10) was higher than that in healthy pregnant group (0.12+/-0.09), with significant difference (P<0.001). Insulin resistance index in GDM group were higher than that in healthy pregnant group, with significant difference (P<0.001). Conclusion: The expression of MIF in placental tissues of GDM women was increased and correlated with insulin resistance in GDM patients, suggesting that MIF may play an important role in the occurrence and development of GDM. PMID- 29179279 TI - [Exploration of death risk factors in patients with antineutrophil cytoplasmic antibody associated vasculitis]. AB - Objectives: Death risk factors of patients with antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV) were explored by the analysis of clinical characteristics of AAV patients, as to provide the basis for early diagnosis and treatment, and reduction of mortality and also improvement of prognosis. Methods: A retrospective study was conducted in patients with AAV which were admitted to this hospital from November 2003 to February 2017, by the contrasts of the similarities and differences of clinical characteristics between the death group and non-death group, for explore the risk factors of death. Results: (1) A total of 66 patients with AAV were included in this study, in which 20 were died (male/female was 12/8), and 46 were still alive, with a total mortality rate of 30.3%.(2)The average age of disease onset in the death group was (67+/-13) years, which was significantly higher than that of the control group (55+/-18, P=0.009). (3)The mean value of vasculitis damage index (VDI) in the death group was (6.4+/-2.5), which was significantly higher than that in the non-death group (4.4+/-2.5, P=0.006). (4)As to multiple organs involvements among the heart, lung, kidney, gastrointestinal tract, central nervous system and other organs, the proportion of three or more organs involvement in the death group was 85% (17/20), which was significantly higher than that in the control group 47.8%(22/46), P=0.004 8.The incidence of heart murmurs, recent premature beats, aortic insufficiency, chronic heart failure/cardiomyopathy, and massive hemoptysis were significantly higher than those in the control group (P<0.05). (5) The incidence of infection in the death group (55%) was significantly higher than that in the control group (28.3%, P=0.038). Conclusion: An onset age of more than 65, multiple organs involvement, especially the occurrence of massive hemoptysis, heart valve diseases, heart failure and other cardiovascular involvements, increased VDI and combination of infections are the risk factors of death in AAV patients. PMID- 29179280 TI - [Prognostic value of right ventricular Tei index and cardiac markers in sepsis]. AB - Objective: To investigate the risk factors of death in patients with sepsis. Methods: From August 2014 to August 2016, 58 patients suffering sepsis in intensive care unit (ICU) of the People's Liberation Army 105 Hospital were prospectively analyzed.All patients were divided into survival group (n=39) and death group (n=19). The patients' gender, age, past medical history, acute physiology and chronic health system II(APACHE II), Sequential organ failure assessment(SOFA) score, B-type natriuretic peptide, lactate, procalcitonin, left ventricle EF%, right ventricle Tei index were measured within 24 h after admission in ICU.Logistic regression analysis was used to evaluate the risk factors of death in septic patients.the hospital mortality of sepsis was assessed by receiver operating character (ROC) curves. Results: The hospital mortality rate of sepsis was 32.8% (19/58). Logistic regression analysis showed that SOFA score [OR=2.34, 95%CI: 1.069-5.258, P<0.01], cTnI[OR=1.21, 95%CI: 1.017-1.437, P=0.032], Tei index[OR=1.56, 95%CI: 1.082-2.263, P=0.017]. The APACHEII, SOFA score, lactic acid, cTnI, Tei index and cTnI combined with Tei index predicted the hospital mortality of sepsis with the area under ROC curve (AUC) of 0.821, 0.848, 0.790, 0.756, 0.962, 0.982, respectively. Conclusion: Tei index and cTnI may be the independent risk factors of sepsis in patients with sepsis, and the incidence of major adverse cardiac events was high. PMID- 29179281 TI - [Effects of different computed high b-values on diffusion weighted imaging scores in Prostate Imaging Reporting and Data System version 2 of prostate cancer in peripheral zone]. AB - Objective: To determine the effects of different computed high b-value on diffusion weighted imaging (DWI) scores in Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) of prostate cancer in peripheral zone. Methods: A retrospective study of 104 cases of prostate cancer in peripheral zone was conducted, all of the patients were histopathologically confirmed by transrectal ultrasound guided saturation biopsy or radical prostatectomy in Tongji Hospital of Tongji University from January 2012 to December 2015.All MRI imaging examinations were performed by using a 3.0T Siemens Verio MRI scanner.The imaging protocol consisted of high-resolution axial and sagittal T(2) weighted imaging (T(2)WI), axial acquired diffusion weighted imaging (aDWI) with b=0, 50, 1 000 s/mm(2) and dynamic contrast-enhanced (DCE) scans.Computed diffusion weighted imaging (cDWI) images with b=1 000, 1 400, 2 000 s/mm(2) were processed by Matlab.These three groups of cDWI images were analyzed according to the PI-RADS v2 criteria, and signal intensity of ratio (SIR) of lesions were analyzed by independent t test and one-way ANOVA in each group. Results: The numbers of cases with a DWI score of 2 and 5 were similar among three groups.Nine cases (33.3%) in all 27 cases with a DWI score of 3 on b=1 000 s/mm(2) upgraded to score 4 when b value rose to 1 400 and 2 000 s/mm(2).The ratios of SIR of lesions in cases upgraded from DWI score 3 to 4 to those unchanged cases on b=1 400 and 2 000 s/mm(2) were 1.86+/-0.21 to 1.61+/-0.27 and 2.18+/-0.26 to 1.75+/-0.30, respectively (t=2.486, t=3.671, both P<0.05). In these 9 cases who upgraded to DWI score 4, SIRs of the lesion were significantly different between groups when b=1 000, 1 400 and 2 000 s/mm(2) (F=10.907, 33.768, 8.043, all P<0.05), and their SIRs increased with the rising of b-value. Conclusions: The computed high b-value (b>=1 400 s/mm(2)) mainly affects cases with a DWI score of 3, but DWI scores would not change neither in b=1 400 s/mm(2) nor in 2 000 s/mm(2) cases. For DWI score in PI-RADS v2 of prostate cancer in peripheral zone, b=1 400 s/mm(2) is probably of more scoring value than b=1 000 or 2 000 s/mm(2).

Methods: Pheomelanin-enriched specimens were prepared from human hair and cutaneous melanoma tissue using alkaline lysis method.Synthetic eumelanin was purchased from a commercial supplier.The same amount (0.02%) of melanin was incubated with the equal enzyme activity (0.2 U/ml) of ligninolytic enzymes for 3 h respectively.The absorbance at 475 nm (A(475)) in the enzyme-catalyzed solution was measured using ELISA microplate reader.The experimental hyperpigmentation model was established in the dorsal skin of brownish guinea pigs using 308 nm excimer light radiation.LiP and heat-inactivated LiP solution were topically applied at each site.Meanwhile, 3% hydroquinone and vehicle cream were used as control.The skin color (L value) was recorded using a CR-10 Minolta chromameter.Corneocytes were collected using adhesive taping method.The amount and distribution of melanin in the corneocytes and skin tissues was visualized by Fontana-Masson staining. Results: All three ligninolytic enzymes showed various degree of eumelanin and pheomelanin decolorization activity.The decolorization activity of LiP, MnP and laccase was 40%-70%, 22%-42% and 9%-21%, respectively.The similar lightening was shown in the skin treated with LiP solution and 3% hydroquinone.The amount of melanin granules in the corneocytes was 199+/-11 by LiP, which was less than that in untreated control (923+/-12) and heat-inactive control (989+/-13). The amount of melanin was decreased in the whole epidermis treated with hydroquinone, the epidermis thickness was increased as well. In contrast, melanin of LiP group was decreased only in the superficial epidermis, the epidermis thickness seemed to be normal. Conclusion: LiP exerts a potent decolorization activity for hair- or skin-derived pheomelanin as well as eumelanin.It remains to be further investigated whether LiP serves as a substitute for hydroquinone in skin lightening products.

AB - Background/Aims: Although many advances in the management of Hirschsprung's disease have recently been achieved, postoperative outcomes of these patients remain difficult in a non-negligible number of cases. Therefore, this study aims at investigating characteristics of anorectal manometry and its relationship with postoperative outcomes during long-term follow-up in Hirschsprung patients. Methods: Patients over 4 years of age operated on for Hirschsprung's disease were interviewed to complete detailed questionnaires on bowel function. The patients who consented to undergo an anorectal manometry during follow-up were enrolled in this study. We investigated their clinical characteristics, manometric findings, and their postoperative bowel function. Results: Nineteen patients out of 53 patients (35.8%) were enrolled, 68.4% who were male. Mean age of patients at manometry was 11.3 +/- 6.3 years. Twelve out of 19 patients (63.2%) were incontinent. The mean anal resting pressures of incontinent patients were significantly lower than continent patients (47 +/- 12 mmHg versus 63 +/- 11 mmHg, P < 0.05, t test). Due to neurological impairment, only 11 patients (57.9%) were able to perform a complete manometry. A dyssynergic defecation was found in 4 patients during strain tests. Maximum tolerated volume of the incontinent patients was significantly lower than that of the continent patients (97 +/- 67 mL versus 181 +/- 74 mL, P < 0.05, t test). Conclusion: Anorectal manometry is an objective method providing useful information that could guide a more adapted management in patients with defecation disorders after Hirschsprung's disease operation. PMID- 29179288 TI - Public Spending on Health Service and Policy Research in Canada, the United Kingdom, and the United States: A Modest Proposal. AB - Health services and policy research (HSPR) represent a multidisciplinary field which integrates knowledge from health economics, health policy, health technology assessment, epidemiology, political science among other fields, to evaluate decisions in health service delivery. Health service decisions are informed by evidence at the clinical, organizational, and policy level, levels with distinct, managerial drivers. HSPR has an evolving discourse spanning knowledge translation, linkage and exchange between research and decision-maker partners and more recently, implementation science and learning health systems. Local context is important for HSPR and is important in advancing health reform practice. The amounts and configuration of national investment in this field remain important considerations which reflect priority investment areas. The priorities set within this field or research may have greater or lesser effects and promise with respect to modernizing health services in pursuit of better value and better population outcomes. Within Canada an asset map for HSPR was published by the national HSPR research institute. Having estimated publicly funded research spending in Canada, we sought identify best available comparable estimates from the United States and the United Kingdom. Investments from industry and charitable organizations were not included in these numbers. This commentary explores spending by the United States, Canada, and the United Kingdom on HSPR as a fraction of total public spending on health and the importance of these respective investments in advancing health service performance. Proposals are offered on the merits of common nomenclature and accounting for areas of investigation in pursuit of some comparable way of assessing priority HSPR investments and suggestions for earmarking such investments to total investment in health services spending. PMID- 29179289 TI - Informal Patient Payments and Bought and Brought Goods in the Western Balkans - A Scoping Review. AB - BACKGROUND: Informal patient payments for healthcare are common in the Western Balkans, negatively affecting public health and healthcare. AIM: To identify literature from the Western Balkans on what is known about informal patient payments and bought and brought goods, to examine their effects on healthcare and to determine what actions can be taken to tackle these payments. METHODS: After conducting a scoping review that involved searching websites and databases and filtering with eligibility criteria and quality assessment tools, 24 relevant studies were revealed. The data were synthesized using a narrative approach that identified key concepts, types of evidence, and research gaps. RESULTS: The number of studies of informal patient payments increased between 2002 and 2015, but evidence regarding the issues of concern is scattered across various countries. Research has reported incidents of informal patient payments on a wide scale and has described various patterns and characteristics of these payments. Although these payments have typically been small - particularly to providers in common areas of specialized medicine - evidence regarding bought and brought goods remains limited, indicating that such practices are likely even more common, of greater magnitude and perhaps more problematic than informal patient payments. Only scant research has examined the measures that are used to tackle informal patient payments. The evidence indicates that legalizing informal patient payments, introducing performance-based payment systems, strengthening reporting, changing mentalities and involving the media and the European Union (EU) or religious organizations in anti-corruption campaigns are understood as some of the possible remedies that might help reduce informal patient payments. CONCLUSION: Despite comprehensive evidence regarding informal patient payments, data remain scattered and contradictory, implying that informal patient payments are a complex phenomenon. Additionally, the data on bought and brought goods illustrate that not much is known about this matter. Although informal patient payments have been studied and described in several settings, there is still little research on the effectiveness of such strategies in the Western Balkans context. PMID- 29179290 TI - Contextualizing Obesity and Diabetes Policy: Exploring a Nested Statistical and Constructivist Approach at the Cross-National and Subnational Government Level in the United States and Brazil. AB - BACKGROUND: This article conducts a comparative national and subnational government analysis of the political, economic, and ideational constructivist contextual factors facilitating the adoption of obesity and diabetes policy. METHODS: We adopt a nested analytical approach to policy analysis, which combines cross-national statistical analysis with subnational case study comparisons to examine theoretical prepositions and discover alternative contextual factors; this was combined with an ideational constructivist approach to policy-making. RESULTS: Contrary to the existing literature, we found that with the exception of cross-national statistical differences in access to healthcare infrastructural resources, the growing burden of obesity and diabetes, rising healthcare costs and increased citizens' knowledge had no predictive affect on the adoption of obesity and diabetes policy. We then turned to a subnational comparative analysis of the states of Mississippi in the United States and Rio Grande do Norte in Brazil to further assess the importance of infrastructural resources, at two units of analysis: the state governments versus rural municipal governments. Qualitative evidence suggests that differences in subnational healthcare infrastructural resources were insufficient for explaining policy reform processes, highlighting instead other potentially important factors, such as state-civil societal relationships and policy diffusion in Mississippi, federal policy intervention in Rio Grande do Norte, and politicians' social construction of obesity and the resulting differences in policy roles assigned to the central government. CONCLUSION: We conclude by underscoring the complexity of subnational policy responses to obesity and diabetes, the importance of combining resource and constructivist analysis for better understanding the context of policy reform, while underscoring the potential lessons that the United States can learn from Brazil. PMID- 29179291 TI - Lost in Translation: Piloting a Novel Framework to Assess the Challenges in Translating Scientific Uncertainty From Empirical Findings to WHO Policy Statements. AB - BACKGROUND: Calls for evidence-informed public health policy, with implicit promises of greater program effectiveness, have intensified recently. The methods to produce such policies are not self-evident, requiring a conciliation of values and norms between policy-makers and evidence producers. In particular, the translation of uncertainty from empirical research findings, particularly issues of statistical variability and generalizability, is a persistent challenge because of the incremental nature of research and the iterative cycle of advancing knowledge and implementation. This paper aims to assess how the concept of uncertainty is considered and acknowledged in World Health Organization (WHO) policy recommendations and guidelines. METHODS: We selected four WHO policy statements published between 2008-2013 regarding maternal and child nutrient supplementation, infant feeding, heat action plans, and malaria control to represent topics with a spectrum of available evidence bases. Each of these four statements was analyzed using a novel framework to assess the treatment of statistical variability and generalizability. RESULTS: WHO currently provides substantial guidance on addressing statistical variability through GRADE (Grading of Recommendations Assessment, Development, and Evaluation) ratings for precision and consistency in their guideline documents. Accordingly, our analysis showed that policy-informing questions were addressed by systematic reviews and representations of statistical variability (eg, with numeric confidence intervals). In contrast, the presentation of contextual or "background" evidence regarding etiology or disease burden showed little consideration for this variability. Moreover, generalizability or "indirectness" was uniformly neglected, with little explicit consideration of study settings or subgroups. CONCLUSION: In this paper, we found that non-uniform treatment of statistical variability and generalizability factors that may contribute to uncertainty regarding recommendations were neglected, including the state of evidence informing background questions (prevalence, mechanisms, or burden or distributions of health problems) and little assessment of generalizability, alternate interventions, and additional outcomes not captured by systematic review. These other factors often form a basis for providing policy recommendations, particularly in the absence of a strong evidence base for intervention effects. Consequently, they should also be subject to stringent and systematic evaluation criteria. We suggest that more effort is needed to systematically acknowledge (1) when evidence is missing, conflicting, or equivocal, (2) what normative considerations were also employed, and (3) how additional evidence may be accrued. PMID- 29179292 TI - Bringing Value-Based Perspectives to Care: Including Patient and Family Members in Decision-Making Processes. AB - BACKGROUND: Recent evidence shows that patient engagement is an important strategy in achieving a high performing healthcare system. While there is considerable evidence of implementation initiatives in direct care context, there is limited investigation of implementation initiatives in decision-making context as it relates to program planning, service delivery and developing policies. Research has also shown a gap in consistent application of system-level strategies that can effectively translate organizational policies around patient and family engagement into practice. METHODS: The broad objective of this initiative was to develop a system-level implementation strategy to include patient and family advisors (PFAs) at decision-making points in primary healthcare (PHC) based on wellestablished evidence and literature. In this opportunity sponsored by the Canadian Foundation for Healthcare Improvement (CFHI) a co-design methodology, also well-established was applied in identifying and developing a suitable implementation strategy to engage PFAs as members of quality teams in PHC. Diabetes management centres (DMCs) was selected as the pilot site to develop the strategy. Key steps in the process included review of evidence, review of the current state in PHC through engagement of key stakeholders and a co-design approach. RESULTS: The project team included a diverse representation of members from the PHC system including patient advisors, DMC team members, system leads, providers, Public Engagement team members and CFHI improvement coaches. Key outcomes of this 18-month long initiative included development of a working definition of patient and family engagement, development of a Patient and Family Engagement Resource Guide and evaluation of the resource guide. CONCLUSION: This novel initiative provided us an opportunity to develop a supportive system-wide implementation plan and a strategy to include PFAs in decision-making processes in PHC. The well-established co-design methodology further allowed us to include value-based (customer driven quality and experience of care) perspectives of several important stakeholders including patient advisors. The next step will be to implement the strategy within DMCs, spread the strategy PHC, both locally and provincially with a focus on sustainability. PMID- 29179293 TI - "Enemies of the People?" Public Health in the Era of Populist Politics Comment on "The Rise of Post-truth Populism in Pluralist Liberal Democracies: Challenges for Health Policy". AB - In this commentary, we review the growth of populist politics, associated with exploitation of what has been termed fake news. We explore how certain words have been used in similar contexts historically, in particular the term "enemy of the people," especially with regard to public health. We then set out 6 principles for public health professionals faced with these situations. First, using their epidemiological skills, they can provide insights into the reasons underlying the growth of populist politics. Second using their expertise in modelling and health impact assessment, they can anticipate and warn about the consequences of populist policies. Third, they can support the institutions that are necessary for effective public health. Fourth they can reclaim the narrative, rejecting hatred and division, to promote social solidarity. Fifth, they can support fact checking and the use of evidence. Finally, they should always remember the lessons of history, and in particular, the way that public health has, on occasions, collaborated with totalitarian and genocidal regimes. PMID- 29179294 TI - "Stop, You're Killing us!" An Alternative Take on Populism and Public Health Comment on "The Rise of Post-truth Populism in Pluralist Liberal Democracies: Challenges for Health Policy". AB - Ewen Speed and Russell Mannion correctly identify several contours of the challenges for health policy in what it is useful to think of as a post democratic era. I argue that the problem for public health is not populism per se, but rather the distinctive populism of the right coupled with the failure of the left to develop compelling counternarratives. Further, defences of 'science' must be tempered by recognition of the unavoidably political dimensions of the (mis)use of scientific findings in public policy. PMID- 29179295 TI - Passed the Age of Puberty: Organizational Networks as a Way to Get Things Done in the Health Field Comment on "Evaluating Global Health Partnerships: A Case Study of a Gavi HPV Vaccine Application Process in Uganda". AB - In this commentary I will demonstrate that the case study of Uganda's Human papilloma virus (HPV) vaccine application partnership provides an excellent example of widening our lens by evaluating the successful HPV vaccine coverage from a network-centric perspective. That implies that the organizational network is seen as the locus of production and that network theories become indispensable to analyze the situation at hand. The case study is, as said, an excellent example of how this can be done and my comments have to be read as an endorsement and a broadening of the discussion of what Carol Kamya and colleagues have presented. It is demonstrated that an organizational network approach can be considered a serious and mature way in understanding public health issues.

AB - BACKGROUND: This manuscript presents evidence-based guidance on the use of 38 percent silver diamine fluoride (SDF) for dental caries management in children and adolescents, including those with special health care needs. A guideline workgroup formed by the American Academy of Pediatric Dentistry developed guidance and an evidence-based recommendation regarding the application of 38 percent SDF to arrest cavitated caries lesions in primary teeth. TYPES OF STUDIES REVIEWED: The basis of the guideline's recommendation is evidence from an existing systematic review "Clinical trials of silver diamine fluoride in arresting caries among children: A systematic review." (JDR Clin Transl Res 2016;1[3]:201-10). A systematic search was conducted in PubMed(r)/MEDLINE, Embase(r), Cochrane Central Register of Controlled Trials, and gray literature databases to identify randomized controlled trials and systematic reviews reporting on the effect of silver diamine fluoride and address peripheral issues such as adverse effects and cost. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of the evidence and the evidence- to-decision framework was employed to formulate a recommendation. RESULTS: The panel made a conditional recommendation regarding the use of 38 percent SDF for the arrest of cavitated caries lesions in primary teeth as part of a comprehensive caries management program. After taking into consideration the low cost of the treatment and the disease burden of caries, panel members were confident that the benefits of SDF application in the target populations outweigh its possible undesirable effects. Per GRADE, this is a conditional recommendation based on low-quality evidence. Conclusions and practical implications: The guideline intends to inform the clinical practices involving the application of 38 percent SDF to enhance dental caries management outcomes in children and adolescents, including those with special health care needs. These recommended practices are based upon the best available evidence to date. A 38 percent SDF protocol is included in Appendix II. PMID- 29179354 TI - Use of Pit-and-Fissure Sealants. AB - BACKGROUND: This article presents evidence-based clinical recommendations for the use of pit-and-fissure sealants on the occlusal surfaces of primary and permanent molars in children and adolescents. A guideline panel convened by the American Dental Association (ADA) Council on Scientific Affairs and the American Academy of Pediatric Dentistry conducted a systematic review and formulated recommendations to address clinical questions in relation to the efficacy, retention, and potential side effects of sealants to prevent dental caries; their efficacy compared with fluoride varnishes; and a head-to-head comparison of the different types of sealant material used to prevent caries on pits-and-fissures of occlusal surfaces. TYPES OF STUDIES REVIEWED: This is an update of the ADA 2008 recommendations on the use of pit-and-fissure sealants on the occlusal surfaces of primary and permanent molars. The authors conducted a systematic search in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and other sources to identify randomized controlled trials reporting on the effect of sealants (available on the U.S. market) when applied to the occlusal surfaces of primary and permanent molars. The authors used the Grading of Recommendations Assessment, Development, and Evaluation approach to assess the quality of the evidence and to move from the evidence to the decisions. RESULTS: The guideline panel formulated 3 main recommendations. They concluded that sealants are effective in preventing and arresting pit-and-fissure occlusal carious lesions of primary and permanent molars in children and adolescents compared with the nonuse of sealants or use of fluoride varnishes. They also concluded that sealants could minimize the progression of non-cavitated occlusal carious lesions (also referred to as initial lesions) that receive a sealant. Finally, based on the available limited evidence, the panel was unable to provide specific recommendations on the relative merits of 1 type of sealant material over the others. Conclusions and practical implications: These recommendations are designed to inform practitioners during the clinical decision-making process in relation to the prevention of occlusal carious lesions in children and adolescents. Clinicians are encouraged to discuss the information in this guideline with patients or the parents of patients. The authors recommend that clinicians re-orient their efforts toward increasing the use of sealants on the occlusal surfaces of primary and permanent molars in children and adolescents. PMID- 29179355 TI - Use of Vital Pulp Therapies in Primary Teeth with Deep Caries Lesions. AB - PURPOSE: This manuscript presents evidence-based guidance on the use of vital pulp therapies for treatment of deep caries lesions in children. A guideline panel convened by the American Academy of Pediatric Dentistry formulated evidence based recommendations on three vital pulp therapies: indirect pulp treatment (IPT; also known as indirect pulp cap), direct pulp cap (DPC), and pulpotomy. METHODS: The basis of the guideline's recommendations was evidence from "Primary Tooth Vital Pulp Therapy: A Systematic Review and Meta-Analysis." (Pediatr Dent 2017;15;39[1]:16-23.) A systematic search was conducted in PubMed(r)/MEDLINE, Embase(r), Cochrane Central Register of Controlled Trials, and trial databases to identify randomized controlled trials and systematic reviews addressing peripheral issues of vital pulp therapies such as patient preferences of treatment and impact of cost. Quality of the evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation approach; the evidence-to-decision framework was used to formulate a recommendation. RESULTS: The panel was unable to make a recommendation on superiority of any particular type of vital pulp therapy owing to lack of studies directly comparing these interventions. The panel recommends use of mineral trioxide aggregate (MTA) and formocresol in pulpotomy treatments; these are recommendations based on moderate quality evidence at 24 months. The panel made weak recommendations regarding choice of medicament in both IPT (moderate-quality evidence [24 months], low quality evidence [48 months]) and DPC (very-low quality evidence [24 months]). Success of both treatments was independent of type of medicament used. The panel also recommends use of ferric sulfate (low-quality evidence), lasers (low-quality evidence), sodium hypochlorite (very low-quality evidence), and tricalcium silicate (very low-quality evidence) in pulpotomies; these are weak recommendations based on low-quality evidence. The panel recommended against the use of calcium hydroxide as pulpotomy medicament in primary teeth with deep caries lesions. Conclusions and practical implications: The guideline intends to inform the clinical practices with evidence-based recommendations on vital pulp therapies in primary teeth with deep caries lesions. These recommendations are based upon the best available evidence to-date.

AB - In all 50 states, health care providers (including dentists) are mandated to report suspected cases of abuse and neglect to social service or law enforcement agencies. The purpose of this report is to review the oral and dental aspects of physical and sexual abuse and dental neglect in children and the role of pediatric care providers and dental providers in evaluating such conditions. This report addresses the evaluation of bite marks as well as perioral and intraoral injuries, infections, and diseases that may raise suspicion for child abuse or neglect. Oral health issues can also be associated with bullying and are commonly seen in human trafficking victims. Some medical providers may receive less education pertaining to oral health and dental injury and disease and may not detect the mouth and gum findings that are related to abuse or neglect as readily as they detect those involving other areas of the body. Therefore, pediatric care providers and dental providers are encouraged to collaborate to increase the prevention, detection, and treatment of these conditions in children.

AB - Traumatic dental injuries (TDIs) of permanent teeth occur frequently in children and young adults. Crown fractures and luxations are the most commonly occurring of all dental injuries. Proper diagnosis, treatment planning and followup are important for improving a favorable outcome. Guidelines should assist dentists and patients in decision making and for providing the best care effectively and efficiently. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialties were included in the group. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion of the IADT board members. The guidelines represent the best current evidence based on literature search and professional opinion. The primary goal of these guidelines is to delineate an approach for the immediate or urgent care of TDIs. In this first article, the IADT Guidelines for management of fractures and luxations of permanent teeth will be presented.

AB - Avulsion of permanent teeth is one of the most serious dental injuries, and a prompt and correct emergency management is very important for the prognosis. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialties were included in the task group. The guidelines represent the current best evidence and practice based on literature research and professionals' opinion. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion or majority decision of the task group. Finally, the IADT board members were giving their opinion and approval. The primary goal of these guidelines is to delineate an approach for the immediate orurgent care of avulsed permanent teeth.

Injuries in the Primary Dentition. AB - Traumatic injuries to the primary dentition present special problems and the management is often different as compared with the permanent dentition. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialities were included in the task group. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion or majority decision of the task group. Finally, the IADT board members were giving their opinion and approval. The primary goal of these guidelines is to delineate an approach for the immediate or urgent care for management of primary teeth injuries. The IADT cannot and does not guarantee favorable outcomes from strict adherence to the guidelines, but believe that their application can maximize the chances of a positive outcome.

The purpose of this study is to investigate the binding sites (receptors) and function of short-form Klotho (Skl). We showed that Skl physically bound to multiple proteins. We found physical and functional interactions between Skl and S-formylglutathione hydrolase (FGH), a key enzyme in the generation of the major cellular anti-oxidant GSH, using co immunoprecipitation-coupled mass spectrometry. We further confirmed the colocalization of Skl and FGH around the nucleus in kidney cells using immunofluorescent staining. Skl positively regulated FGH gene expression via Kid3 transcription factor. Overexpression of Skl increased FGH mRNA and protein expression while silencing of Skl attenuated FGH mRNA and protein expression. Klotho gene mutation suppressed FGH expression in red blood cells and kidneys resulting in anemia and kidney damage in mice. Overexpression of Skl increased total GSH production and the GSH/GSSG ratio, an index of anti-oxidant capacity, leading to a decrease in intracellular H2O2 and superoxide levels. The antioxidant activity of Skl was eliminated by silencing of FGH, indicating that Skl increased GSH via FGH. Interestingly, Skl directly interacted with FGH and regulated its function. Site-directed mutagenesis of the N-glycan-modified residues in Skl abolished its antioxidant activity, suggesting that these N glycan moieties are important features that interact with FGH. Specific mutation of Asp to Ala at site 285 resulted in a loss of anti-oxidant activity of Skl, suggesting that N-glycosylation at site 285 is the key mechanism that determines Skl activity. Therefore, this study demonstrates, for the first time, that Skl regulates anti-oxidant GSH generation via interaction with FGH through N glycosylation. PMID- 29179435 TI - Genome-wide 5-hydroxymethylcytosine patterns in human spermatogenesis are associated with semen quality. AB - We performed immunofluorescent analysis of DNA hydroxymethylation and methylation in human testicular spermatogenic cells from azoospermic patients and ejaculated spermatozoa from sperm donors and patients from infertile couples. In contrast to methylation which was present throughout spermatogenesis, hydroxymethylation was either high or almost undetectable in both spermatogenic cells and ejaculated spermatozoa. On testicular cytogenetic preparations, 5-hydroxymethylcytosine was undetectable in mitotic and meiotic chromosomes, and was present exclusively in interphase spermatogonia Ad and in a minor spermatid population. The proportions of hydroxymethylated and non-hydroxymethylated diploid and haploid nuclei were similar among samples, suggesting that the observed alterations of 5 hydroxymethylcytosine patterns in differentiating spermatogenic cells are programmed. In ejaculates, a few spermatozoa had high 5-hydroxymethylcytosine level, while in the other ones hydroxymethylation was almost undetectable. The percentage of highly hydroxymethylated (5-hydroxymethylcytosine-positive) spermatozoa varied strongly among individuals. In patients from infertile couples, it was higher than in sperm donors (P<0.0001) and varied in a wider range: 0.12-21.24% versus 0.02-0.46%. The percentage of highly hydroxymethylated spermatozoa correlated strongly negatively with the indicators of good semen quality - normal morphology (r=-0.567, P<0.0001) and normal head morphology (r= 0.609, P<0.0001) - and strongly positively with the indicator of poor semen quality: sperm DNA fragmentation (r=0.46, P=0.001). Thus, the immunocytochemically detected increase of 5hmC in individual spermatozoa is associated with infertility in a couple and with deterioration of sperm parameters. We hypothesize that this increase is not programmed, but represents an induced abnormality and, therefore, it can be potentially used as a novel indicator of semen quality. PMID- 29179436 TI - Osteoblast-oriented differentiation of BMSCs by co-culturing with composite scaffolds constructed using silicon-substituted calcium phosphate, autogenous fine particulate bone powder and alginate in vitro. AB - Autogenous bone graft is the best for spinal fusion in clinics, however, lacking sources, bleeding and infection are limited its practice. Seeking alternative materials are urgent for orthopaedic surgeon. Here, we evaluated osteoblast oriented differentiation of rabbit BMSCs by co-culturing with composite scaffolds constructed using silicon-substituted-CaP-fine particulate bone powder-alginate. Using CCk8-kit, biocompatibility was evaluated by testing BMSCs proliferation; morphology and survival of osteoblasts within scaffolds were observed using EM and HE staining; growth factors and related genes were detected using RT-PCR. HE staining showed spindle-shaped BMSCs after the 3rd passage; EM data showed that uneven surface and longitudinal section were observed with scattered distribution of 5-100 mm interspaces, which leave enough space for BMSCs adhesion and growth. Interestingly, at 14-day culture with HE staining, osteocytes within the scaffolds grew well with regular shape and integrate structure. RT-PCR results showed that expression levels of BMP2, TGF-b and COL-I, ALP, OPN were increased significantly and time-dependently. Collectively, all mentioned effects were more obvious in co-culture BMSCs with scaffolds than those with other components. Immunohistochemistry showed that positive OPN expression was detected at 7-day co culturing BMSCs with scaffold, rather than other situations. These results suggest that composite scaffolds constructed with Si-CaP-fine particulate bone powder-alginate have a certain degree of biocompatibility and bioactivity to promote osteoblast-oriented BMSCs differentiation. PMID- 29179434 TI - Growth of malignant extracranial tumors alters microRNAome in the prefrontal cortex of TumorGraft mice. AB - A wide array of central nervous system complications, neurological deficits, and cognitive impairments occur and persist as a result of systemic cancer and cancer treatments. This condition is known as chemo brain and it affects over half of cancer survivors. Recent studies reported that cognitive impairments manifest before chemotherapy and are much broader than chemo brain alone, thereby adding in tumor brain as a component. The molecular mechanisms of chemo brain are under investigated, and the mechanisms of tumor brain have not been analyzed at all. The frequency and timing, as well as the long-term persistence, of chemo brain and tumor brain suggest they may be epigenetic in nature. MicroRNAs, small, single-stranded non-coding RNAs, constitute an important part of the cellular epigenome and are potent regulators of gene expression. miRNAs are crucial for brain development and function, and are affected by a variety of different stresses, diseases and conditions. However, nothing is known about the effects of extracranial tumor growth or chemotherapy agents on the brain microRNAome. We used the well-established TumorGraft TM mouse models of triple negative (TNBC) and progesterone receptor positive (PR+BC) breast cancer, and profiled global microRNAome changes in tumor-bearing mice upon chemotherapy, as compared to untreated tumor-bearing mice and intact mice. Our analysis focused on the prefrontal cortex (PFC), based on its roles in memory, learning, and executive functions, and on published data showing the PFC is a target in chemo brain. This is the first study showing that tumor presence alone significantly impacted the small RNAome of PFC tissues. Both tumor growth and chemotherapy treatment affected the small RNAome and altered levels of miRNAs, piRNAs, tRNAs, tRNA fragments and other molecules involved in post-transcriptional regulation of gene expression. Amongst those, miRNA changes were the most pronounced, involving several miRNA families, such as the miR-200 family and miR-183/96/182 cluster; both were deregulated in tumor-bearing and chemotherapy-treated animals. We saw that miRNA deregulation was associated with altered levels of brain-derived neurotrophic factor (BDNF), which plays an important role in cognition and memory and is one of the known miRNA targets. BDNF downregulation has been associated with an array of neurological conditions and could be one of the mechanisms underlying tumor brain and chemo brain. In the future our study could serve as a roadmap for further analysis of cancer and chemotherapy's neural side effects, and differentially expressed miRNAs should be explored as potential tumor brain and chemo brain biomarkers. PMID- 29179439 TI - Next generation sequencing identified novel heterozygous nonsense mutation in CNGB1 gene associated with retinitis pigmentosa in a Chinese patient. AB - Retinitis pigmentosa (RP) is a severe hereditary eye disease characterized by progressive degeneration of photoreceptors and subsequent loss of vision. Retinitis pigmentosa (RP) is a clinically and genetically heterogeneous group of retinal diseases. Germline mutations of CNGB1 is associated with retinitis pigmentosa. We have identified and investigated a 34-year-old Chinese man with markedly have night vision blindness and loss of midperipheral visual field. The proband also lose his far peripheral visual field and also central vision. Proband's retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Target exome capture based next generation sequencing and Sanger sequencing identified novel nonsense mutation, c.1917G>A and a reported mutation, c.2361C>A, in the CNGB1 gene. Both the nonsense mutations are predicted to lead to the formation of a premature stop codon which finally results into formation of truncated CNGB1 protein product which finally predicted to be disease causing. According to the variant classification guidelines of ACMG, these two variants are categorized as "likely pathogenic" variants. Our findings expand the mutational spectra of CNGB1 and are valuable in the mutation-based pre- and post natal screening and genetic diagnosis for retinitis pigmentosa. PMID- 29179437 TI - High glucose promotes vascular smooth muscle cell proliferation by upregulating proto-oncogene serine/threonine-protein kinase Pim-1 expression. AB - Serine/threonine kinase proviral integration site for Moloney murine leukemia virus 1 (Pim-1) plays an essential role in arterial wall cell proliferation and associated vascular diseases, including pulmonary arterial hypertension and aortic wall neointima formation. Here we tested a role of Pim-1 in high-glucose (HG)-mediated vascular smooth muscle cell (VSMC) proliferation. Pim-1 and proliferating cell nuclear antigen (PCNA) expression levels in arterial samples from streptozotocin-induced hyperglycemia rats were increased, compared with their weak expression in normoglycemic groups. In cultured rat VSMCs, HG led to transient Pim-1 expression decline, followed by sustained expression increase at both transcriptional and translational levels. Immunoblot analysis demonstrated that HG increased the expression of the 33-kDa isoform of Pim-1, but at much less extent to its 44-kDa plasma membrane isoform. D-glucose at a concentration of 25 mmol/L showed highest activity in stimulating Pim-1 expression. Both Pim-1 inhibitor quercetagetin and STAT3 inhibitor stattic significantly attenuated HG induced VSMC proliferation and arrested cell cycle progression at the G1 phase. Quercetagetin showed no effect on Pim-1 expression but decreased the phosphorylated-Bad (T112)/Bad ratio in HG-treated VSMCs. However, stattic decreased phosphorylated-STAT3 (Y705) levels and caused transcriptional and translational down-regulation of Pim-1 in HG-treated VSMCs. Our findings suggest HG-mediated Pim-1 expression contributes to VSMC proliferation, which may be partly due to the activation of STAT3/Pim-1 signaling. PMID- 29179438 TI - Valproate hampers podocyte acquisition of immune phenotypes via intercepting the GSK3beta facilitated NFkB activation. AB - Glomerular podocytes are able to transdifferentiate under disease conditions, acquire de novo immune phenotypes and behave as immunocompetent cells, like phagocytes or antigen-presenting cells. Upon stimulation with lipopolysaccharide (LPS), a prototypical pathogen-associated molecular pattern, podocytes demonstrated de novo expression of a variety of NFkB-dependent immune molecules that are pivotal for immune response, including major histocompatibility complex (MHC) class II, costimulatory molecule CD80, lysosomal protease cathepsin L as well as CC chemokine ligand 2 and 5, ultimately resulting in podocyte dysfunction, characterized by cellular shrinkage, a spindle-like or asterlike cell shape and impairment of actin cytoskeleton integrity. The LPS-elicited podocyte phenotypic changes were concurrent with nuclear factor (NF) kB phosphorylation, which was associated with glycogen synthase kinase (GSK) 3beta overactivity, marked by a diminished inhibitory phosphorylation of GSK3beta. In contrast, valproate, an anticonvulsant and mood stabilizer, offset GSK3beta overactivity in LPS-injured podocytes and mitigated NFkB activation and podocyte acquisition of immune phenotypes as well as the ensuing cytopathic changes, podocyte cytoskeleton disorganization and dysfunction. The protective effect of valproate was strikingly blunted in podocytes expressing the constitutively active GSK3beta, suggesting an essential role of inhibitory phosphorylation of GSK3beta. In vivo in LPS-injured mice, valproate therapy abolished GSK3beta overactivity in glomeruli and attenuated podocyte injury and albuminuria, concomitant with a lessened NFkB activation and diminished induction of diverse podocytopathic immune molecules in podocytes and glomeruli. Taken together, valproate directly protects against podocyte injury and hampers podocyte acquisition of de novo immune phenotypes via intercepting the GSK3beta facilitated NFkB activation. PMID- 29179440 TI - Toxoplasma gondii excretory/secretory antigens (TgESAs) suppress pro-inflammatory cytokine secretion by inhibiting TLR-induced NF-kappaB activation in LPS stimulated murine macrophages. AB - Excretory/secretory antigens (ESAs) produced by Toxoplasma gondii enable this parasite to invade and survive within the host cells through immunomodulation. In this study, the modulating effects of T. gondii excretory/secretory antigens (TgESAs) on the Ana-1 murine macrophage cell line were evaluated. Ana-1 cells were incubated with several concentrations of TgESAs, and the resulting effects on cellular viability, phagocytotic ability, and apoptosis induction were determined. Pro-inflammatory and anti-inflammatory cytokine secretion, nitric oxide production, toll-like receptor expression, and nuclear translocation of NF kappaB were all measured after incubation with TgESAs. After TgESAs treatment, the proliferation and phagocytosis ability of Ana-1 cells decreased, and apoptosis was induced in a dose dependent manner. Analysis of Ana-1 cell culture supernatants showed that TgESAs not only upregulated secretion of anti inflammatory cytokines (interleukin-10 and transforming growth factor-beta1), they also inhibited secretion of pro-inflammatory cytokines (tumor necrosis factor-alpha and interleukin-1beta). Additionally, TgESAs inhibited nitric oxide production, toll-like receptor (TLR) 2 and 4 activation, and the nuclear translocation of NF-kappaB in lipopolysaccharide-stimulated Ana-1 macrophages. These results suggest TgESAs inhibit the functional activity of Ana-1 murine macrophages by inhibiting TLR-induced NF-kappaB activation, which suppresses pro inflammatory cytokine secretion. PMID- 29179441 TI - High-affinity human PD-L1 variants attenuate the suppression of T cell activation. AB - The activated T cells can be suppressed by programed death-1 (PD-1) axis through low affinity interaction between PD-1 and PD-ligand 1 (PD-L1) in solution or on antigen presenting cells. In clinic, the concentration of soluble PD-L1 in peripheral blood negatively correlates with cancer prognosis. However, there is little information about the relation between the affinity of PD-1/PD-L1 interaction and the suppressive capacity of PD-1 axis. In this study, we analyzed inhibitory roles of high affinity soluble human PD-L1 (hPD-L1) variants, which were generated with directed molecular evolution. Resultant two clones L3C7-hPD L1 and L3B3-hPD-L1 showed over 20 folds greater affinity than that of native hPD L1. We found that L3B3-hPD-L1 and L3C7-hPD-L1 could compete with an anti-PD-1 antibody (EH12.1) for binding to hPD-1. More importantly, although native soluble hPD-L1 can induce suppressive effects on activated T cells, we found L3B3-hPD-L1 and L3C7-hPD-L1 attenuated the strength of PD-1 axis for suppressing the proliferation and interferon gamma (IFN-gamma) secretion of PBMC. In conclusion, our data provide direct evidence in which immune checkpoint receptor-ligand interactive strength can alter the the suppressive function, in particular, the suppressive capacity of PD-1 axis could be decreased with enhanced affinity of soluble PD-L1 and PD-1 interaction. Our study might provide a new direction for manipulating immune checkpoints. PMID- 29179442 TI - A Bayesian pick-the-winner design in a randomized phase II clinical trial. AB - Purpose: Many phase II clinical trials evaluate unique experimental drugs/combinations through multi-arm design to expedite the screening process (early termination of ineffective drugs) and to identify the most effective drug (pick the winner) to warrant a phase III trial. Various statistical approaches have been developed for the pick-the-winner design but have been criticized for lack of objective comparison among the drug agents. Methods: We developed a Bayesian pick-the-winner design by integrating a Bayesian posterior probability with Simon two-stage design in a randomized two-arm clinical trial. The Bayesian posterior probability, as the rule to pick the winner, is defined as probability of the response rate in one arm higher than in the other arm. The posterior probability aims to determine the winner when both arms pass the second stage of the Simon two-stage design. Results: When both arms are competitive (i.e., both passing the second stage), the Bayesian posterior probability performs better to correctly identify the winner compared with the Fisher exact test in the simulation study. In comparison to a standard two-arm randomized design, the Bayesian pick-the-winner design has a higher power to determine a clear winner. In application to two studies, the approach is able to perform statistical comparison of two treatment arms and provides a winner probability (Bayesian posterior probability) to statistically justify the winning arm. Conclusion: We developed an integrated design that utilizes Bayesian posterior probability, Simon two-stage design, and randomization into a unique setting. It gives objective comparisons between the arms to determine the winner. PMID- 29179443 TI - SH003 suppresses breast cancer growth by accumulating p62 in autolysosomes. AB - Drug markets revisits herbal medicines, as historical usages address their therapeutic efficacies with less adverse effects. Moreover, herbal medicines save both cost and time in development. SH003, a modified version of traditional herbal medicine extracted from Astragalus membranaceus (Am), Angelica gigas (Ag), and Trichosanthes Kirilowii Maximowicz (Tk) with 1:1:1 ratio (w/w) has been revealed to inhibit tumor growth and metastasis on highly metastatic breast cancer cells, both in vivo and in vitro with no toxicity. Meanwhile, autophagy is imperative for maintenance cellular homeostasis, thereby playing critical roles in cancer progression. Inhibition of autophagy by pharmacological agents induces apoptotic cell death in cancer cells, resulting in cancer treatment. In this study, we demonstrate that SH003-induced autophagy via inhibiting STAT3 and mTOR results in an induction of lysosomal p62/SQSTM1 accumulation-mediated reactive oxygen species (ROS) generation and attenuates tumor growth. SH003 induced autophagosome and autolysosome formation by inhibiting activation of STAT3- and mTOR-mediated signaling pathways. However, SH003 blocked autophagy-mediated p62/SQSTM1 degradation through reducing of lysosomal proteases, Cathepsins, resulting in accumulation of p62/SQSTM1 in the lysosome. The accumulation of p62/SQSTM1 caused the increase of ROS, which resulted in the induction of apoptotic cell death. Therefore, we conclude that SH003 suppresses breast cancer growth by inducing autophagy. In addition, SH003-induced p62/SQSTM1 could function as an important mediator for ROS generation-dependent cell death suggesting that SH003 may be useful for treating breast cancer. PMID- 29179444 TI - Mechanism study of isoflavones as an anti-retinoblastoma progression agent. AB - Isoflavones, bioactive soy compounds, are known to exhibit anticancer activities. The present study investigated the anticancer activities of isoflavones on human retinoblastoma Y79 cells in vitro and in vivo. An MTT cell viability assay showed that the half maximal inhibitory concentration value of isoflavones against human retinoblastoma Y79 cells is 1.23 +/- 0.42 MUmol/l. Flow cytometry analysis indicated that isoflavones blocked G1/S progression. Western blot analysis demonstrated that the mammalian target of rapamycin (mTOR) pathway in Y79 cells was inhibited by isoflavones, with a concomitant decrease in cyclin E1, which accounted for the isoflavone-mediated G1 phase arrest. Isoflavones also inhibited human retinoblastoma growth in vivo; western blot analysis showed inhibition of mTOR and downregulation of cyclin E1 in an isoflavone-treated xenograft mouse model. Together, these results illustrate that isoflavones inhibit retinoblastoma tumour growth in vitro and vivo and that inactivation of the mTOR pathway and downregulation of cyclin E1 is involved in this action. The results of this study suggest that isoflavones could be tested as promising anti-retinoblastoma agent. PMID- 29179446 TI - Targeted interference of SIN3A-TGIF1 function by SID decoy treatment inhibits Wnt signaling and invasion in triple negative breast cancer cells. AB - Cancer cell invasion is an obligatory step for metastatic dissemination that contributes to rapid relapse and a poorer survival in triple negative breast cancer (TNBC) patients. Development of novel therapeutic strategies to block tumor invasion is an unmet need in the treatment of cancer. We reported that the selective inhibition of the PAH2 domain of SIN3A protein function markedly suppressed metastatic dissemination to the lungs in TNBC xenograft bearing mice. Here, we show that TNBC cell lines treated with Sin3 interaction domain (SID) decoy peptides that bind to PAH2 display a strong in vitro inhibition of transwell invasion. This is accompanied by actin cytoskeleton reorganization with increased cortical actin deposition and downregulation of known Wnt target genes that are associated with epithelial to mesenchymal transition (EMT) and cancer cell invasion. Wnt pathway inhibition by SID decoy peptide was confirmed by decreased Wnt reporter activity and altered cytoplasmic localization of nuclear beta-catenin. TGIF1, a transcription factor that modulates Wnt signaling and known to interact with the PAH2 domain of SIN3A, can be dissociated from the SIN3A complex by SID decoys. TGIF1 knockdown inhibits WNT target genes and in vitro cell invasion suggesting that TGIF1 might be a key target of the SID decoys to block tumor invasion. Taken together, targeting SIN3 function using SID decoys is a novel strategy to reverse invasion and the EMT program in TNBC translating into the inhibition of metastasis dissemination and eradication of residual disease. PMID- 29179445 TI - ADAMTS16 mutations sensitize ovarian cancer cells to platinum-based chemotherapy. AB - Ovarian cancer is one of the most lethal malignant tumors in women. The prognosis of ovarian cancer patients depends, in part, on their response to platinum-based chemotherapy. Our recent analysis of genomics and clinical data from the Cancer Genome Atlas demonstrated that somatic mutations of ADAMTS 1, 6, 8, 9, 15, 16, 18 and L1 genes were associated with higher sensitivity to platinum and longer progression-free survival, overall survival, and platinum-free survival duration in 512 patients with high-grade serous ovarian carcinoma. Among the ADAMTS mutations, ADAMTS16 is the most commonly affected gene in ovarian cancer. However, the functional role of these mutations in ovarian cancer cells is largely unknown. We performed in vitro studies to compare the functional effects of the six identified ADAMTS missense mutations on the platinum sensitivity of ovarian cancer cells. We also used a well-characterized in vivo mouse model to evaluate the response of ovarian cancer cells with ADAMTS16 mutations to platinum based therapy. Our results showed that exogenously expressed ADAMTS16 missense mutations inhibited cell growth or sensitized tumor cells to cisplatin and inhibited tumor growth in vivo. Orthotopic xenograft experiments showed that mice injected with ovarian cancer cells that exogenously expressed ADAMTS16 mutations had a better response to cisplatin treatment. Thus, these functional studies provide evidence that mutations of ADAMTS16 actively contribute to therapeutic response in ovarian cancer. PMID- 29179447 TI - The tumor suppressor RASSF1A induces the YAP1 target gene ANKRD1 that is epigenetically inactivated in human cancers and inhibits tumor growth. AB - The Hippo pathway regulates organ size, growth and comprises several tumor related factors, including the oncoprotein YAP1 and the tumor suppressor RASSF1A. RASSF1A is frequently epigenetically inactivated in cancer. In our study, we analyzed the effect of RASSF1A on the function of YAP1. Expression of YAP1 resulted in the downregulation of several tumor suppressor genes and induction of S-phase. Co-expression with RASSF1A normalized the expression levels of these tumor suppressors and induced a G0-G1 arrest and apoptosis. This effect was associated with the reduction of MDM2 and the increase of p53. These data suggest that the tumor suppressor RASSF1A inhibits the oncogenic potential of YAP1. Additionally, we could show that ANKRD1 is a YAP1 target gene that is induced by RASSF1A. Further analysis revealed that ANKRD1 is epigenetically inactivated in human cancer. ANKRD1 expression induced the expression of TP53 as well as BAX and CDKN1A and reduced colony formation of cancer cells. We found that ANKRD1 interacts with p53 and is involved in the destabilization of MDM2. Additionally, our data indicate that the tumor-suppressive effect of ANKRD1 depends on the presence of p53. These results suggest that ANKRD1 is a tumor-suppressive downstream target of the Hippo pathway that is epigenetically silenced in human cancer. PMID- 29179448 TI - Overexpression of SYF2 promotes cell proliferation and correlates with poor prognosis in human breast cancer. AB - SYF2, a known cell cycle regulator, is reported to be involved in cell cycle arrest by interacting with cyclin-D-type binding protein 1. In the present study, we investigated the role of SYF2 in human breast cancer (BC) progression. SYF2 was highly upregulated in BC tissues and cell lines, as per Western blot and immunohistochemistry analysis. The SYF2 expression level had a significant correlation with the tumor grade and Ki-67 expression. In vitro starvation refeeding experiment and SYF2-siRNA transfection assay demonstrated that SYF2 could promote proliferation of BC cells, while SYF2 knockdown resulted in cells cycle arrest at G1/S phase, reducing the cell growth rate of BC cells. These results indicated that SYF2 promotes human BC progression by accelerating the BC cells' proliferation. SYF2 could be a novel therapeutic target in human BC therapies. PMID- 29179449 TI - The role of adrenomedullin in the pathogenesis of gastric cancer. AB - Adrenomedullin has been shown to be overexpressed in many tumors, including gastric cancer tumors; however, its mechanism of action remains unclear. In this study, we examined the role of adrenomedullin in the pathogenesis of gastric cancer. Using clinical specimens and immunohistochemistry, we found that the expression levels of adrenomedullin and its receptors are inordinately elevated as compared to the adjacent non-tumor gastric tissues. We used siRNA gene silencing, in BGC-823 gastric cancer cell lines, to target adrenomedullin genes, and found that increased adrenomedullin expression results in the proliferation of tumor cells, tumor invasion, and metastasis. Furthermore, we found that under hypoxic conditions, gastric cancer BGC-823 cells exhibit higher expression levels of adrenomedullin and various other related proteins. Our results indicate the involvement of adrenomedullin in microvessel proliferation and partially in the release of hypoxia in solid tumors. Knockdown of adrenomedullin expression, at the protein level, reduced the levels of phosphoprotein kinase B and B-cell lymphoma 2 but increased the levels of cleaved-caspase3 and Bcl 2 associated x protein (Bax). Therefore, we hypothesized siRNA targeting of adrenomedullin genes inhibits various serine/threonine kinases via a signaling pathway that induces cell apoptosis. SiRNA targeting of adrenomedullin genes and green fluorescent control vectors were used to transfect BGC-823 cells, and western blot analyses were used to detect changes in the rates of autophagy in related proteins using confocal laser scanning microscopy. No significant changes were detected. Therefore, the knockdown of adrenomedullin and its receptors may represent a novel treatment strategy for gastric cancer. PMID- 29179451 TI - Anti-cancer effects of dopamine in human glioma: involvement of mitochondrial apoptotic and anti-inflammatory pathways. AB - Despite the emergence of innovative cancer treatment strategies, the global burden imposed by malignant glioma is expected to increase; thus, new approaches for treating the disease are urgently required. Dopamine, a monoamine catecholamine neurotransmitter, is currently regarded as an important endogenous regulator of tumor growth. Dopamine may play an important role in glioma treatment; however, the mechanism underlying the anti-tumor activity of dopamine remains poorly understood. Here, we explored the potential roles of dopamine in glioma and highlight the importance of endogenous regulators of tumor growth. We report that dopamine inhibited glioma cell proliferation. We investigated the biological functions of dopamine via migration, colony formation and apoptosis assays in glioma cells. We also evaluated cytochrome c release from the mitochondria and p50 and p65 subcellular localization by fluorescence microscopy. We performed western blotting and real-time quantitative polymerase chain reaction to detect apoptosis and inflammatory marker protein and gene expression levels, respectively. NF-kappaB p50/p65 nuclear localization was analyzed after U87MG and U251 cells were treated with dopamine. The in vivo anti-tumor efficacy of dopamine was also analyzed in xenograft mice. Taken together, our results indicated that dopamine induced apoptosis by activating the cytochrome c and caspase-dependent apoptotic pathway. Moreover, dopamine markedly down-regulated inflammation-related protein expression levels and p50/p65 NF-kappaB nuclear localization in tumor cells, thereby inhibiting increases in tumor weight and size in xenograft mice. Thus, therapies targeting the mitochondrial apoptotic and anti-inflammatory signaling pathways regulated by dopamine may represent promising treatments for human glioma. PMID- 29179452 TI - Novel galeterone analogs act independently of AR and AR-V7 for the activation of the unfolded protein response and induction of apoptosis in the CWR22Rv1 prostate cancer cell model. AB - The androgen receptor (AR) has long been the primary target for the treatment of prostate cancer (PC). Despite continuous efforts to block AR activity through ligand depletion, AR antagonism, AR depletion and combinations thereof, advanced PC tumors remain resilient. Herein, we evaluate two galeterone analogs, VNPT-178 and VNLG-74A, in PC cell models of diverse androgen and AR dependence attempting to delineate their mechanisms of action and potential clinical utility. Employing basic biochemical techniques, we determined that both analogs have improved antiproliferative and anti-AR activities compared to FDA-approved abiraterone and enzalutamide. However, induction of apoptosis in these models is independent of the AR and its truncated variant, AR-V7, and instead likely results from sustained endoplasmic reticulum stress and deregulated calcium homeostasis. Using in silico molecular docking, we predict VNPT-178 and VNLG-74A bind the ATPase domain of BiP/Grp78 and Hsp70-1A with greater affinity than the AR. Disruption of 70 kDa heat shock protein function may be the underlying mechanism of action for these galeterone analogs. Therefore, despite simultaneously antagonizing AR activity, AR and/or AR-V7 expression alone may inadequately predict a patient's response to treatment with VNPT-178 or VNLG-74A. Future studies evaluating the context-specific limitations of these compounds may provide clarity for their clinical application. PMID- 29179450 TI - Angiotensin-(1-7) counteracts the transforming effects triggered by angiotensin II in breast cancer cells. AB - Angiotensin (Ang) II, the main effector peptide of the renin-angiotensin system, has been implicated in multiple aspects of cancer progression such as proliferation, migration, invasion, angiogenesis and metastasis. Ang-(1-7), is a biologically active heptapeptide, generated predominantly from AngII by the enzymatic activity of angiotensin converting enzyme 2. Previous studies have shown that Ang-(1-7) counterbalances AngII actions in different pathophysiological settings. In this study, we have analysed the impact of Ang-(1 7) on AngII-induced pro-tumorigenic features on normal murine mammary epithelial cells NMuMG and breast cancer cells MDA-MB-231. AngII stimulated the activation of the survival factor AKT in NMuMG cells mainly through the AT1 receptor. This PI3K/AKT pathway activation also promoted epithelial-mesenchymal transition (EMT). Concomitant treatment of NMuMG cells with AngII and Ang-(1-7) completely abolished EMT features induced by AngII. Furthermore, Ang-(1-7) abrogated AngII induced migration and invasion of the MDA-MB-231 cells as well as pro-angiogenic events such as the stimulation of MMP-9 activity and VEGF expression. Together, these results demonstrate for the first time that Ang-(1-7) counteracts tumor aggressive signals stimulated by AngII in breast cancer cells emerging the peptide as a potential therapy to prevent breast cancer progression. PMID- 29179453 TI - MicroRNA deregulation in nonalcoholic steatohepatitis-associated liver carcinogenesis. AB - Hepatocellular carcinoma (HCC) is the fastest-rising cause of cancer-related death in the United States. Recent epidemiological studies have identified nonalcoholic steatohepatitis (NASH), a progressive form of nonalcoholic fatty liver disease (NAFLD), as a major risk factor for HCC. Elucidating the underlying mechanisms associated with the development of NASH-derived HCC is critical for identifying early biomarkers for the progression of the disease and for treatment and prevention. In the present study, using liver samples from C57BL/6J mice submitted to the Stelic Animal Model (STAM) of NASH-associated liver carcinogenesis, we investigated the role of microRNA (miRNA) alterations in the pathogenesis of NASH-derived HCC. We found substantial alterations in the expression of miRNAs, with the greatest number occurring in full-fledged HCC. Mechanistically, altered miRNA expression was associated with activation of major hepatocarcinogenesis-related pathways, including the TGF-beta, Wnt/beta-catenin, ERK1/2, mTOR, and EGF signaling. In addition, the over-expression of the miR-221 3p and miR-222-3p and oncogenic miR-106b~25 cluster was accompanied by the reduced protein levels of their targets, including E2F transcription factor 1 (E2F1), phosphatase and tensin homolog (PTEN), and cyclin-dependent kinase inhibitor 1 (CDKN1A). Importantly, miR-93-5p, miR-221-3p, and miR-222-3p were also significantly over-expressed in human HCC. These findings suggest that aberrant expression of miRNAs may have mechanistic significance in NASH associated liver carcinogenesis and may serve as an indicator for the development of NASH-derived HCC. PMID- 29179454 TI - Plasma microRNA alterations between EGFR-activating mutational NSCLC patients with and without primary resistance to TKI. AB - Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have obtained excellent therapeutic effects against non-small cell lung cancer (NSCLC) harboring activating EGFR mutations. However, some patients have exhibited primary resistance which becomes a major obstacle in effective treatment of NSCLC. The mechanisms of EGFR-TKIs resistance involved are still poorly understood. Many studies suggest that miRNAs play an important role in regulating drug sensitivity of EGFR-TKIs. The aim of the present study was to examine differentially expressed miRNAs in plasma between EGFR-TKIs sensitive and EGFR TKIs primary resistance patients. MiRNA microarray of plasma from patients' blood identified 16 differentially expressed miRNAs of which 15 (hsv2-miR-H19, hsa-miR 744-5p, hsa-miR-3196, hsa-miR-3153, hsa-miR-4791, hsa-miR-4803, hsa-miR-4796-3p, hsa-miR-372-5p, hsa-miR-138-2-3p, hsa-miR-16-1-3p, hsa-miR-1469, hsa-miR-585-3p, ebv-miR-BART14-5p, hsa-miR-769-3p, hsa-miR-548aq-5p) were down regulated while only hsa-miR-503-3p was up regulated in primary resistant patients' plasma. Volcano plot and hierarchical clustering were performed to examine the accuracy of the miRNAs. Then validation with quantitative real-time PCR was performed and the result was in accordance with the array data. Functional analysis of these differentially expressed miRNAs with Ingenuity Pathway Analysis (IPA) revealed a common signaling network including MYC, CCND1, IGF1 and RELA. In conclusion, our finding may play important role in understanding the mechanisms underlying the problem and should be further evaluated as potential biomarkers in primary resistance of NSCLC. PMID- 29179455 TI - Lack of adiponectin and adiponectin receptor 1 contributes to benign prostatic hyperplasia. AB - PURPOSE: The incidence of benign prostatic hyperplasia increases among obese individuals, but few studies have fully explained the underlying mechanisms. Adiponectin has drawn much attention in recent years due to its protective role in obesity-related diseases. Here we aimed to investigate the possible molecular mechanisms and clinical significance of adiponectin in relation to benign prostatic hyperplasia. METHODS: We analyzed data from 98 Chinese men, including 48 BPH cases and 50 controls in a case-control study. Then, we utilized a tissue microarray analysis to examine expression of AdipoR1 and p-p90RSK in normal and hyperplastic prostate tissues. These studies were followed by various in vitro approaches to examine the anti-proliferation effect and signaling pathways of adiponectin involved in benign prostatic hyperplasia. RESULTS: Lower serum adiponectin levels were independently associated with larger prostate volume and an increased risk of benign prostatic hyperplasia. Benign prostatic hyperplasia tissues had a decreased expression of AdipoR1 and increased expression of p p90RSK compared with normal prostate tissues. in vitro, adiponectin inhibited the proliferation of prostatic epithelial and stromal cells and arrested cells in the G0/G1 phase by decreasing phosphorylation of the MEK-ERK-p90RSK axis. CONCLUSIONS: Our results suggest a possible negative regulatory mechanism in which adiponectin signaling antagonizes ERK-mediated cell proliferation, and a deficiency in adiponectin could facilitate the proliferation of prostate cells and consequently contribute to benign prostatic hyperplasia. PMID- 29179456 TI - Combined Ki67 and ERCC1 for prognosis in non-keratinizing nasopharyngeal carcinoma underwent chemoradiotherapy. AB - This study aimed to assess the predictive value of combined Ki67 and ERCC1 in distant metastasis-free nasopharyngeal carcinoma. 334 such cases were retrospectively assessed. Immunohistochemistry was used to evaluate Ki67 and ERCC1 protein levels in tumor tissues. Associations of Ki67 and ERCC1 amounts with clinical characteristics and survival were analyzed. Medium follow-up was 48.7 months; overall survival (OS), disease-free survival (DFS), distant metastasis-free survival (DMFS), and local recurrence-free survival (LRFS) were 91.3%, 76.0%, 82.0%, and 91.9%, respectively. High Ki67 expression was found in 35.6% patients, and positively correlated with clinical- and N- staging (P = 0.005, P < 0.001); 4-year OS, DFS, and DMFS were significantly lower in the high Ki67 group than patients with low-medium expression (P = 0.001, P = 0.012, P = 0.007). High ERCC1 expression was found in 35.3% of patients, and positively correlated with clinical- and T- staging. Compared with low ERCC1 expression cases, 4-year OS, DFS, DMFS, and LRFS were decreased significantly in those with high levels. High Ki67 and ERCC1 levels were related to adverse prognoses of OS (HR=4.977, 95% CI 2.31-12.292, P<0.001), DFS (HR = 4.178, 95% CI 2.421-7.212, P < 0.001), DMFS (HR = 3.722, 95% CI 2.028-7.015, P < 0.001), and LRFS (HR = 3.689, 95% CI 1.423-9.566, P = 0.007). Compared with the low-medium Ki67 and low ERCC1 groups, no significant difference in survival prognosis was obtained in the low medium Ki67 and high ERCC1 groups, and patients with high Ki67 and low ERCC1 levels. Combined Ki67 and ERCC1 can better predict nasopharyngeal carcinoma prognosis than individual parameters. PMID- 29179457 TI - Traditional Chinese medicine Danggui Buxue Tang inhibits colorectal cancer growth through induction of autophagic cell death. AB - Purpose: The induction of autophagic cell death is an important process in the development of anticancer therapeutics. We aimed to evaluate the activity of the ancient Chinese decoction Danggui Buxue Tang (DBT) against colorectal cancer (CRC) and the associated autophagy-related mechanism. Materials and methods: CT26 CRC cells were implanted into syngeneic BALB/c mice for the tumor growth assay. DBT extracts and DBT-PD (polysaccharide-depleted) fractions were orally administered. The toxicity profiles of the extracts were analyzed using measurements of body weight, hemogram, and biochemical parameters. The morphology of tissue sections was observed using light and transmission electron microscopy. Western blotting and small interference RNA assays were used to determine the mechanism. Results: DBT-PD and DBT, which contained an equal amount of DBT-PD, inhibited CT26 syngeneic tumor growth. In the tumor specimen, the expression of microtubule-associated proteins 1A/1B light chain 3B (LC3B) was upregulated by DBT-PD and DBT. The development of autophagosomes was observed via transmission electron microscopy in tumors treated with DBT-PD and DBT. In vitro experiments for mechanism clarification demonstrated that DBT-PD could induce autophagic death in CT26 cells accompanied by LC3B lipidation, downregulation of phospho p70s6k, and upregulation of Atg7. RNA interference of Atg7, but not Atg5, partially reversed the effect of DBT-PD on LC3B lipidation and expression of phospho-p70s6k and Atg7. The changes in ultrastructural morphology and LC3B expression induced by DBT-PD were also partially blocked by the knockdown of Atg7 mRNA. Conclusion: DBT induced autophagic death of colorectal cancer cells through the upregulation of Atg7 and modulation of the mTOR/p70s6k signaling pathway. PMID- 29179458 TI - Plasma N-acetylputrescine, cadaverine and 1,3-diaminopropane: potential biomarkers of lung cancer used to evaluate the efficacy of anticancer drugs. AB - Polyamines have been widely investigated as potential biomarkers for various types of cancers, including lung cancer, which is one of the most common causes of death from cancer worldwide. This study was carried out to evaluate the value of polyamines that serve as early diagnostic and cancer progression markers as well as drug evaluation for lung cancer (squamous cell carcinoma of lung, SCCL). SCCL was induced in Wistar rats by intratracheal instillation of 3 methylcholanthrene and treated with three different anti-cancer drugs, Aidi injections, fluorouracil, and a combination of them. After carcinogenesis for 28, 70 and 98 days and therapy for 28 and 56 days, the polyamine levels in plasma of SCCL, healthy and treated rats were determined using a UHPLC-MS/MS assay base on the means of targeted metabolomics. Results showed that increased N acetylputrescine, cadaverine and 1,3-diaminopropane levels were associated with progression of SCCL. The levels of cadaverine and 1,3-diaminopropane returned to normal after administration of the three different kinds of anticancer drug. In addition, the suitability of using N-acetylputrescine, cadaverine and 1,3 diaminopropane as biomarkers was confirmed by PLS-DA and ROC analysis. It can provide an innovative and effective way for the clinical diagnosis, prevention and treatment of lung cancer, and stimulate a theoretical basis for the design and development of new anticancer drugs. At the same time, this increased the clinical options for polyamines as cancer biomarkers. PMID- 29179459 TI - SLC3A2, antigen of mAb 3G9, promotes migration and invasion by upregulating of mucins in gastric cancer. AB - Solute carrier family 3 member 2 (SLC3A2) has been reported to be highly expressed in a variety of carcinomas. However, the function of SLC3A2 in gastric carcinoma (GC) has not been well explored. Monoclonal antibody (mAb) 3G9, generated from immunogen of various human GC cell lines, has been shown to bind to GC tissues specifically. In this study, we identified the target antigen of mAb 3G9 as SLC3A2, and detected the expression profile of SLC3A2 in a panel of gastric cancer cell lines and GC tumor tissues. We found that the increased expression of SLC3A2 was associated with serosal invasion in GC patients. Knockout of SLC3A2 suppressed the migration and invasion of BGC-823 cells in vitro and in vivo, whereas overexpression of SLC3A2 in NCI-N87 cells promoted the migration and invasion in vitro and in vivo. Mechanistic investigations suggested that MUC1, MUC16 and MUC5B were the downstream genes of SLC3A2 in GC cells. Taken together, our data suggested that SLC3A2 promoted the aggressive phenotype of GC by upregulating several mucin genes expression and may serve as a potential biomarker for diagnosis and target therapy. PMID- 29179460 TI - GSK-3beta phosphorylation-dependent degradation of ZNF281 by beta-TrCP2 suppresses colorectal cancer progression. AB - Zinc finger protein 281 (ZNF281) has been recently shown to be critical for CRC progression. However, the immediate upstream regulators of ZNF281 remain unclear. Here we reported that the E3 ligase the beta-transducin repeat-containing protein 2 (beta-TrCP2) governs the ubiquitination and degradation of ZNF281. In human CRC specimens, endogenous beta-TrCP2 were inversely correlated with ZNF281. Beta TrCP2 reversed the phenotype of CRC cell with overexpressed ZNF281. Moreover, we found that glycogen synthase kinase 3beta (GSK-3beta), not GSK-alpha, could bind to and phosphorylate ZNF281 at one consensus motif (TSGEHS; phosphorylation site is shown in italics), which promotes the interaction of ZNF281 with beta-TrCP2, not beta-TrCP1, and leads to the subsequent ubiquitination and degradation of phosphorylated ZNF281. A mutant of ZNF281 (ZNF281-S638A) is much more stable than wild-type ZNF281 because ZNF281-S638A mutant abolishes the phosphorylation by GSK 3beta and can not be ubiquitinated and degraded by beta-TrCP2. Conversely, ZNF281 transcriptionally repressed the expression of beta-TrCP2, indicating a negative feedback loop between ZNF281 and beta-TrCP2 in CRC cells. These findings suggest that the turnover of ZNF281 by beta-TrCP2 might provide a potentially novel treatment for patients with CRC. PMID- 29179461 TI - Differential expression profiles of long non-coding RNAs as potential biomarkers for the early diagnosis of acute myocardial infarction. AB - Acute myocardial infarction (AMI) is a major cause of morbidity and mortality worldwide. The early diagnosis of AMI is crucial for deciding the course of treatment and saving lives. Long non-coding RNAs (lncRNAs) are recently discovered ncRNA class and their dysregulated expression has been implicated in cardiovascular diseases. In this study, we analyzed lncRNA expression pattern by using two microarray datasets of AMI and healthy samples from the Gene Expression Omnibus (GEO) database and tried to identify novel AMI-related lncRNAs and investigate the predictive roles of lncRNAs in the early diagnosis of AMI. From the discovery cohort, 11 differentially expressed lncRNAs were identified as candidate biomarkers that were validated in the discovery cohort, internal cohort and an independent cohort, respectively. Hierarchical clustering analysis suggested that the expression pattern of these 11 candidate lncRNA biomarkers was closely associated with disease status of samples. Then a lncRNA risk classifier was developed by integrating expression value of 11 differentially expressed lncRNAs using support vector machine (SVM) algorithm. The results of leaving one out cross-validation (LOOCV) suggested that the lncRNA risk classifier has a good discrimination between AMI patients and healthy samples with the area under ROC curve (AUC) of 0.955, 0.92 and 0.701 in three cohorts, respectively. Functional enrichment analysis suggested that these 11 candidate lncRNA biomarkers might be involved in inflammation- and immune-related biological processes. Our study indicates the potential roles in the early diagnosis of AMI and will improve our understanding of the molecular mechanism of the occurrence and recurrence of AMI. PMID- 29179462 TI - Toll-like receptor 5 gene polymorphism is associated with breast cancer susceptibility. AB - Toll-like receptor 5 (TLR5) plays a fundamental role in immune responses. Recent findings suggest the TLR5 expression level affects cancer progression and development. In the present study, our examination of 256 breast carcinomas specimens revealed that TLR5 is overexpressed in breast carcinomas, and that TLR5 overexpression correlated with lymph node metastasis and cancer grade (p<0.01). In a case-control study, we also analyzed associations between TLR5 single nucleotide polymorphisms (SNPs) and breast cancer risk. Compared were 516 Chinese Han women diagnosed mainly with infiltrative ductal carcinoma and 520 age-matched healthy controls. The nonsense SNP rs5744168 causes truncation of the TLR5 transmembrane signaling domain and was associated with breast cancer risk (p<0.05). However, no statistical association was detected between SNP rs5744168 and any of the clinical parameters tested. Our findings thus indicate that TLR5 SNP rs5744168 is associated with sporadic breast cancer occurrence. PMID- 29179463 TI - Olaquindox disrupts tight junction integrity and cytoskeleton architecture in mouse Sertoli cells. AB - Sertoli cells, by creating an immune-privileged and nutrition supporting environment, maintain mammalian spermatogenesis and thereby holds the heart of male fertility. Olaquindox, an effective feed additive in livestock industry, could potentially expose human into the risk of biological hazards due to its genotoxicity and cytotoxicity, highlighting the significance of determining its bio-safety regarding human reproduction. Herein, we deciphered the detrimental effects of olaquindox on male fertility by mechanistically unraveling how olaquindox intervenes blood-testis barrier in mouse. Olaquindox (400 MUg/ml) exposure significantly compromised tight junction permeability function, decreased or dislocated the junction proteins (e.g., ZO-1, occludin and N cadherin) and attenuated mTORC2 signaling pathway in primary Sertoli cells. Furthermore, olaquindox disrupted F-actin architecture through interfering with the expression of actin branching protein complex (CDC42-N-WASP-Arp3) and actin bunding protein palladin. Olaquindox also triggered severely DNA damage and apoptosis while inhibiting autophagic flux in Sertoli cell presumably due to the exacerbated generation of reactive oxygen species (ROS). Pre-treatment with antioxidant N-acetylcysteine effectively ameliorated olaquindox-induced exhaustion of ZO-1 and N-Cadherin proteins, DNA damage and apoptosis. More significantly, olaquindox disrupted the epigenetic status in Sertoli cells with hypermethylation and concomitantly hypoacetylation of H3K9 and H3K27. Overall, our study determines olaquindox targets Sertoli cells to affect BTB function through tight junction proteins and F-actin orgnization, which might disrupt the process of spermatogenesis. PMID- 29179464 TI - Urokinase-type plasminogen activator receptor inhibits apoptosis in triple negative breast cancer through miR-17/20a suppression of death receptors 4 and 5. AB - Dissection and understanding of the molecular pathways driving triple-negative breast cancer (TNBC) are urgently needed to develop efficient tailored therapies. Aside from cell invasion and metastasis, the urokinase-type plasminogen activator receptor (uPAR) has been linked to apoptosis resistance in breast tumors. We explored the mechanism of uPAR-disrupted apoptosis in breast cancer. We found that depletion of uPAR by RNAi increases death receptor 4 (DR4) and death receptor 5 (DR5) expression and triggers TRAIL-induced apoptosis in TNBC cells. The microRNAs miR-17-5p and miR-20a inhibit cell apoptosis via suppression of DR4/DR5. We provide evidence that uPAR enhances miR-17-5p/20a expression through upregulation of c-myc. Blocking miR-17-5p/20a with antagomiRNA suppressed the growth of uPAR-overexpressing breast tumor xenografts in mice. These results indicate that uPAR suppresses cell apoptosis by inhibiting the c-myc-miR 17/5p/20a-DR4/DR5 pathway. Therapy directed at uPAR-induced miR-17/20a is a potential option for breast cancer and TNBC. PMID- 29179465 TI - Shikonin reduces tamoxifen resistance through long non-coding RNA uc.57. AB - Tamoxifen resistance is a serious problem in the endocrine therapy of breast cancer. Long non-coding RNAs play important roles in tumor development. In this study, we revealed the involvement of lncRNA uc.57 and its downstream gene BCL11A in TAM resistance. Tamoxifen-resistant MCF-7R cells showed lower expression of uc.57 and higher expression of BCL11A mRNA and protein than the parental MCF-7 cells. Moreover, levels of uc.57 mRNA were lower and BCL11A mRNA were higher in breast cancer tissues than in precancerous breast tissues. Shikonin treatment reduced tamoxifen resistance in MCF-7R cells both in vitro and in vivo, targeting uc.57/BCL11A. Fluorescence in situ hybridization and RNA immunoprecipitation analyses showed that uc.57 binds to BCL11A. Uc.57 overexpression downregulated BCL11A and reduced tamoxifen resistance in MCF-7R cells both in vitro and in vivo. BCL11A knockdown also reduced tamoxifen resistance by inhibiting PI3K/AKT and MAPK signaling pathways. It thus appears shikonin reduces tamoxifen resistance of MCF-7R breast cancer cells by inducing uc.57, which downregulates BCL11A to inhibit PI3K/AKT and MAPK signaling pathways. PMID- 29179466 TI - Anti-angiogenic drugs: direct anti-cancer agents with mitochondrial mechanisms of action. AB - Components of the mitochondrial electron transport chain have recently gained much interest as potential therapeutic targets. Since mitochondria are essential for the supply of energy that is required for both angiogenic and tumourigenic activity, targeting the mitochondria represents a promising potential therapeutic approach for treating cancer. Here we investigate the established anti angiogenesis drugs combretastatin A4, thalidomide, OGT 2115 and tranilast that we hypothesise are able to exert a direct anti-cancer effect in the absence of vasculature by targeting the mitochondria. Drug cytotoxicity was measured using the MTT assay. Mitochondrial function was measured in intact isolated mitochondria using polarography, fluorimetry and enzymatic assays to measure mitochondrial oxygen consumption, membrane potential and complex I-IV activities respectively. Combretastatin A4, OGT 2115 and tranilast were both shown to decrease mitochondrial oxygen consumption. OGT 2115 and tranilast decreased mitochondrial membrane potential and reduced complex I activity while combretastatin A4 and thalidomide did not. OGT 2115 inhibited mitochondrial complex II-III activity while combretastatin A4, thalidomide and tranilast did not. Combretastatin A4, thalidomide and OGT 2115 induced bi-phasic concentration dependent increases and decreases in mitochondrial complex IV activity while tranilast had no evident effect. These data demonstrate that combretastatin A4, thalidomide, OGT 2115 and tranilast are all mitochondrial modulators. OGT 2115 and tranilast are both mitochondrial inhibitors capable of eliciting concentration-dependent reductions in cell viability by decreasing mitochondrial membrane potential and oxygen consumption. PMID- 29179467 TI - Knockdown of long non-coding RNA Taurine Up-Regulated 1 inhibited doxorubicin resistance of bladder urothelial carcinoma via Wnt/beta-catenin pathway. AB - In genitourinary system, bladder cancer (BC) is the most common and lethal malignant tumor, which most common type is bladder urothelial carcinoma (BUC). Long non-coding RNA (lncRNA) Taurine Up-Regulated 1 (TUG1) gene is high-expressed in several malignant tumors, including BC. In this study, over-expression of TUG1 was found in BUC tissues and cell line resistant to doxorubicin (Dox). Knockdown of TUG1 inhibited the Dox resistance and promoted the cytotoxicity induced by Dox in T24/Dox cells. TUG1 knockdown also depressed the Wnt/beta-catenin pathway, and the activation the Wnt/beta-catenin pathway partly reversed the inhibitory effects of TUG1 knockdown on Dox resistance in T24/Dox cells. In conclusion, up regulation of lncRNA TUG1 was related with the poor response of BUC patients to Dox chemotherapy, knockdown of TUG1 inhibited the Dox resistance of BUC cells via Wnt/beta-catenin pathway. These findings might assist in the discovery of novel potential diagnostic and therapeutic target for BUC, thereby improve the effects of clinical treatment in patients. PMID- 29179468 TI - Pharmacometabolomics identifies dodecanamide and leukotriene B4 dimethylamide as a predictor of chemosensitivity for patients with acute myeloid leukemia treated with cytarabine and anthracycline. AB - Clinical responses to standard cytarabine plus anthracycline regimen in acute myeloid leukemia (AML) are heterogeneous and there is an unmet need for biological predictors of response to this regimen. Here, we applied a pharmacometabolomics approach to identify potential biomarkers associated with response to this regimen in AML patients. Based on clinical response the enrolled 82 patients were subdivided into two groups: complete remission(CR) responders (n=42) and non-responders (n=40). Metabolic profiles of pre-treatment serum from patients were analyzed by ultra-high performance liquid chromatography coupled with mass spectrometry and the metabolic differences between the two groups were investigated by multivariate statistical analysis. A metabolite panel containing dodecanamide and leukotriene B4 dimethylamide (LTB4-DMA) had the power capacity to differentiate the two groups of patients, yielding an area under the receiver operating characteristic of 0.945 (85.2% sensitivity and 88.9% specificity) in the training set and 0.944(84.6% sensitivity and 80.0% specificity) in the test set. The patients with high levels of LTB4-DMA and low amounts of dodecanamide had good sensitivity to chemotherapeutic agents. The possible reasons were that dodecanamide was produced by leukemic cells as a lipolytic factor to fuel their growth with a potential role in drug resistance and LTB4-DMA was a potent leukotriene B4 antagonist that could be applicable in the treatment of AML. These preliminary results demonstrates the feasibility of relating chemotherapy responses with pre-treatment metabolic profiles of AML patients, and pharmacometabolomics may be a useful tool to select patients that are more likely to benefit from cytarabine plus anthracycline chemotherapy. PMID- 29179469 TI - Bioluminescence imaging of a tumor-selective, thymidine kinase-defective vaccinia virus Guang9 strain after intratumoral or intraperitoneal administration in mice. AB - Vaccinia virus has been used as an oncolytic virus because of its capacity to preferentially infect tumors rather than normal tissues. The vaccinia Tian Tan strain, used as a vaccine against smallpox for millions of people in China, is a promising candidate for cancer therapy. In this study, we constructed an attenuated Tian Tan strain of Guang9 with a disrupted thymidine kinase gene to enhance tumor selectivity and an inserted firefly luciferase to monitor the viral distribution by in vivo bioluminescence imaging. Living animal imaging confirmed the high specificity of vaccinia Guang9 for tumor targeting after intratumoral and intraperitoneal administration. In addition, the vaccinia Guang9 strain produced higher in vivo luciferase activity and endured longer in immunocompromised nude mice than in immunocompetent C57BL/6 mice, all of which had been tumor-challenged. The luciferase activity and viral titers in excised tissues confirmed these conclusions. These data provide evidence for the safety and efficacy of the clinical application of vaccinia virus, which would be a promising approach for cancer therapy. PMID- 29179470 TI - Constitutive activated STAT3 is an essential regulator and therapeutic target in esophageal squamous cell carcinoma. AB - Esophageal carcinoma is among the most common cancers worldwide and a leading cause of cancer death [1]. Large numbers of studies indicated that chronic inflammation is closely associated with its development [21, 25]. Furthermore, the JAK/STAT pathway, which plays a critical role in inflammation and immunity, has been implied in a number of malignancies [11]. It has been shown that targeting the pathway affected the growth, apoptosis, and metastasis of cultured esophageal squamous cell carcinoma cells [26]. We found in the present study that STAT3 is constitutively activated in a subgroup of esophageal squamous cell carcinoma cell lines and primary tumors. Altered expressions of STAT3 target genes were found in these tumors by using RNAseq and qPCR analysis. Cytokines that activate STAT3 affected the expression of STAT3 target genes and promoted the growth of the ESCC cells, which could be blocked by STAT3 inhibitor and specific siRNA. Inhibition of STAT3 also suppressed the growth and colony formation, and induced apoptosis in the esophageal squamous cell carcinoma cells containing constitutively activated STAT3. Furthermore, the STAT3 inhibitor effectively blocked the growth of patient-derived tumor xenografts that harbored phosphorylated STAT3, but acted less effective on the xenografts derived from primary tumors that contained low levels of activated STAT3. These results indicated that activated STAT3 plays a critical role in the survival and growth of a subgroup of esophageal squamous cell carcinoma, and may serve as a target for precision therapeutic intervention. PMID- 29179471 TI - Histone deacetylase 6 inhibition counteracts the epithelial-mesenchymal transition of peritoneal mesothelial cells and prevents peritoneal fibrosis. AB - The role of histone deacetylase 6 (HDAC6) in peritoneal fibrosis remains unknown. In this study, we examined the effect of HDAC6 inhibition on the epithelial mesenchymal transition (EMT) of peritoneal mesothelial cells and development of peritoneal fibrosis. Treatment with tubastatin A, a highly selective HDAC6 inhibitor, or silencing of HDAC6 with siRNA inhibited transforming growth factor beta1-induced EMT, as evidenced by decreased expression of alpha-smooth muscle actin, collagen I and preserved expression of E-cadherin in cultured human peritoneal mesothelial cells. In a mouse model of peritoneal fibrosis induced by high glucose dialysate, administration of TA prevented thickening of the submesothelial region and decreased expression of collagen I and alpha-SMA. Mechanistically, tubastatin A treatment inhibited expression of TGF-beta1 and phosphorylation of Smad-3, epidermal growth factor receptor, STAT3, and NF kappaBp65. HDAC6 inhibition also suppressed production of multiple inflammatory cytokines/chemokines and reduced the infiltration of macrophages to the injured peritoneum. Moreover, tubastatin A was effective in inhibiting peritoneal increase of CD31(+) blood vessels and expression of vascular endothelial growth factor in the injured peritoneum. Collectively, these results suggest that HDAC6 inhibition can attenuate peritoneal fibrosis by inhibiting multiple pro-fibrotic signaling pathways, EMT, inflammation and blood vessel formation. PMID- 29179472 TI - BCRP expression in schwannoma, plexiform neurofibroma and MPNST. AB - Background: peripheral nerve sheath tumors comprise a broad spectrum of neoplasms. Vestibular schwannomas and plexiform neurofibromas are symptomatic albeit benign, but a subset of the latter pre-malignant lesions will transform to malignant peripheral nerve sheath tumors (MPNST). Surgery and radiotherapy are the primary strategies to treat these tumors. Intrinsic resistance to drug therapy characterizes all three tumor subtypes. The breast cancer resistance protein BCRP is a transmembrane efflux transporter considered to play a key role in various biological barriers such as the blood brain barrier. At the same time it is associated with drug resistance in various tumors. Its potential role in drug resistant tumors of the peripheral nervous system is largely unknown. Objective: to assess if BCRP is expressed in vestibular schwannomas, plexiform neurofibromas and MPNST. Material and methods: immunohistochemical staining for BCRP was performed on a tissue microarray composed out of 22 vestibular schwannomas, 10 plexiform neurofibromas and 18 MPNSTs. Results: sixteen out of twenty-two vestibular schwannomas (73%), nine out of ten plexiform neurofibromas (90%) and six out of eighteen MPNST (33%) expressed BCRP in the vasculature. Tumor cells were negative. Conclusion: BCRP is present in the vasculature of vestibular schwannomas, plexiform neurofibromas and MPSNT. Therefore, it may reduce the drug exposure of underlying tumor tissues and potentially cause failure of drug therapy. PMID- 29179473 TI - A complex microsatellite at chromosome 7q33 as a new prognostic marker of colorectal cancer. AB - Disease-specific markers are critical for early diagnosis, targeted therapy and prognostic prediction of diseases. Current study reports a complex microsatellite as a new prognostic marker of sporadic colorectal cancer. This microsatellite located at Chromosome 7q33 is composed of three tetranucleotide tandem repeats, (TTCC)2(TCCC)5(TCCT)7, flanked by a CT-rich sequence. We analyzed polymorphisms of this microsatellite in 158 sporadic colorectal cancer, 143 matched normal adjacent tissues (NAT) and 150 health donors. Our results showed that this complex microsatellite was instable with polymorphic frequency of 77.2% in colorectal cancer, 52.4% in NAT and 54.7% in health donors (p<0.01) when compared to reference sequence. In the three tandem repeats, (TCCT)7 site was most polymorphic accounting for over 70.0% of polymorphisms in this complex microsatellite, followed by (TTCC)2 site for approximately 20%. Polymorphisms in (TCCC)5 was rare. Polymorphisms at the (TCCT)7 site were mainly insertions of 1 to 4 copies of TCCT (88.6%), and deletions occurred in about 6.4% of cases. The (TTCC)2 site was featured with one copy TTCC insertions. Pair-wise analyses between colorectal tumors and NAT revealed that 88 of 121 (72.7%) tumors displayed expansion, contraction or both in these tetranucleotide tandem repeats when compared to NAT. A cross-analysis with clinicopathological data of 158 colorectal cancers revealed that polymorphic alterations of the microsatellite associated with less lymphatic metastasis (p<0.001), and the colorectal cancer patients with polymorphic changes in this microsatellite demonstrated better survival (n=112, p=0.0058). Together these data suggest that this complex microsatellite is a potential prognostic marker of sporadic colorectal cancer. PMID- 29179474 TI - Lung cancer mortality clusters in Shandong Province, China: how do they change over 40 years? AB - Lung cancer has long been a major health problem in China. This study aimed to examine the temporal trend and spatial pattern of lung cancer mortality in Shandong Province from 1970 to 2013. Lung cancer mortality data were obtained from Shandong Death Registration System and three nationwide retrospective cause of-death surveys. A Purely Spatial Scan Statistics method with Discrete Poisson models was used to detect possible high-risk spatial clusters. The results show that lung cancer mortality rate in Shandong Province increased markedly from 1970 1974 (7.22 per 100,000 person-years) to 2011-2013 (56.37/100, 000). This increase was associated with both demographic and non-demographic factors. Several significant spatial clusters with high lung cancer mortality were identified. The most likely cluster was located in the northern region of Shandong Province during both 1970-1974 and 2011-2013. It appears the spatial pattern remained largely consistent over the last 40 years despite the absolute increase in the mortality rates. These findings will help develop intervention strategies to reduce lung cancer mortality in this large Chinese population. PMID- 29179475 TI - Genetic variants in the inflammation pathway as predictors of recurrence and progression in non-muscle invasive bladder cancer treated with Bacillus Calmette Guerin. AB - : Inflammation plays a critical role in the etiology of several cancers and may affect their clinical outcome. Our objective was to assess the association of genetic variants within the inflammation pathway with recurrence and progression among non-muscle invasive bladder cancer (NMIBC) patients with or without Bacillus Calmette-Guerin (BCG) treatment. We genotyped 372 single nucleotide polymorphisms (SNPs) in 27 selected genes within the inflammation pathway in 349 patients diagnosed with NMIBC, followed by internal validation in 322 additional patients. We used Cox proportional hazards regression analyses to identify SNPs as predictors for recurrence and progression. In the discovery phase, we identified 20 variants that were significantly associated with recurrence outcomes and 15 SNPs significantly associated with progression in patients treated with BCG but not in the transurethral resection (TUR)-only group. In BCG treated patients, rs7089861 was the only SNP significantly associated with risk of progression in both the discovery phase (Hazard Ratio [HR]=3.15, 95% Confidence Interval [CI]: 1.38-7.22, P<0.01) and validation phase (HR=3.84, 95% CI: 1.64-9.0, P=0.002; meta-analysis HR=3.47, 95% CI: 1.92-6.28, P<0.001). Two variants, rs1800686 and rs2071081, had probable association with HRs of the same trend in the discovery and validation groups (meta-analysis P=0.002). These findings supported the notion that genetic variation of inflammation pathway may impact clinical outcome of NMIBC patients treated with BCG immunotherapy. Further validation of these results in order to improve risk stratification to identify patients most likely to benefit from BCG treatment versus upfront radical cystectomy and future development of potential targeted therapies are warranted. Significance Statement: In a two-stage study, we identified several genetic variants in the inflammation pathway associated with recurrence and progression in early-stage bladder cancer. In particular, variant rs7089861 was validated for progression among patients who underwent BCG immunotherapy. Several other variants showed marginal association with recurrence or progression. These findings suggest that inflammatory pathway genetic variants may influence clinical outcome of bladder cancer patients and help to select patients most appropriate for BCG treatment. PMID- 29179476 TI - Hyperoside alleviates adriamycin-induced podocyte injury via inhibiting mitochondrial fission. AB - Podocyte injury underlies many forms of glomerular diseases. Our previous study showed that hyperoside, a naturally occurring flavonoid, could decrease albuminuria at the early stage of diabetic nephropathy by ameliorating renal damage and podocyte injury. However, its protective mechanism against podocyte injury is unknown. A previous study demonstrated that hyperoside might inhibit amyloid beta-protein-induced neurotoxicity by suppressing mitochondrial dysfunction. Both mitochondrial dysfunction and its upstream determinant mitochondrial fission were closely related to podocyte injury. Thus, in the current study, we tested the effect of hyperoside on mitochondrial dysfunction and mitochondrial fission in adriamycin (ADR)-induced podocyte injury. In the mice model of ADR-induced nephropathy, hyperoside treatment inhibited ADR-induced albuminuria and podocyte injury. Meanwhile, hyperoside also blocked ADR-induced mitochondrial dysfunction and mitochondrial fission. Consistently, in cultured human podocytes, hyperoside suppressed ADR-induced podocyte injury, mitochondrial dysfunction and mitochondrial fission. All these results indicated that hyperoside might inhibit ADR-induced mitochondrial dysfunction and podocyte injury through suppressing mitochondrial fission both in vivo and in vitro. The underlying mechanisms which we revealed support the therapeutic effects of hyperoside for a broad range of glomerular diseases. PMID- 29179477 TI - Long noncoding RNA NNT-AS1 promotes hepatocellular carcinoma progression and metastasis through miR-363/CDK6 axis. AB - Long non-coding RNAs (lncRNAs) have been tested to act as important regulator in liver cancer genesis and progression. LncRNA Nicotinamide Nucleotide Transhydrogenase-antisense RNA1 (NNT-AS1) has been reported to participate in the tumorigenesis. However, the exact molecular mechanism of NNT-AS1 in hepatocellular carcinoma (HCC) is still unknown. In present study, our team identified the up-regulated expression of NNT-AS1 in HCC tissue and cell lines compared with adjacent noncancerous tissue and normal cells. Moreover, HCC patients with high NNT-AS1 levels had poor prognosis than that with low NNT-AS1 level (p=0.0089). In vitro, gain- and loss-of-function experiments revealed that enhanced NNT-AS1 expression promoted the proliferation ability and alleviated the cycle arrest and apoptosis, while NNT-AS1 knockdown suppressed the proliferation and induced G0/G1 phase arrest and apoptosis. In vivo, NNT-AS1 knockdown inhibited the HCC neoplastic tumor volume and weight. Bioinformatics analysis and luciferase reporter assay validated that miR-363 targeted NNT-AS1 and CDK6 3' UTR. MiR-363 was down-regulated in HCC tissue and cells. NNT-AS1 competed with CDK6 for miR-363 binding and could increase CDK6 expression. In summary, our results suggest the oncogenic role of NNT-AS1 in HCC tumorigenesis through miR 363/CDK6 axis, providing a novel therapeutic target for human HCC. PMID- 29179478 TI - 64Cu-ATSM internal radiotherapy to treat tumors with bevacizumab-induced vascular decrease and hypoxia in human colon carcinoma xenografts. AB - Bevacizumab, an anti-vascular endothelial growth factor (VEGF) antibody, is an antiangiogenic agent clinically used for various cancers. However, repeated use of this agent leads to tumor-decreased vascularity and hypoxia with activation of an HIF-1 signaling pathway, which results in drug delivery deficiency and induction of malignant behaviors in tumors. Here, we developed a novel strategy to treat tumors with bevacizumab-induced vascular decrease and hypoxia using 64Cu diacetyl-bis (N4-methylthiosemicarbazone) (64Cu-ATSM), a potential theranostic agent, which possesses high tissue permeability and can target over-reduced conditions under hypoxia in tumors, with a human colon carcinoma HT-29 tumor bearing mouse model. The long-term treatment with bevacizumab caused decreased blood vessel density and activation of an HIF-1 signaling pathway; increased uptake of 64Cu-ATSM was also observed despite limited blood vessel density in HT 29 tumors. In vivo high-resolution SPECT/PET/CT imaging confirmed reduced vascularity and increased proportion of 64Cu-ATSM uptake areas within the bevacizumab-treated tumors. 64Cu-ATSM therapy was effective to inhibit tumor growth and prolong survival of the bevacizumab-treated tumor-bearing mice without major adverse effects. In conclusion, 64Cu-ATSM therapy effectively enhanced anti tumor effects in tumors with bevacizumab-induced vascular decrease and hypoxia. 64Cu-ATSM therapy could represent a novel approach as an add-on to antiangiogenic therapy. PMID- 29179479 TI - Splenectomy is associated with an aggressive tumor growth pattern and altered host immunity in an orthotopic syngeneic murine pancreatic cancer model. AB - The purpose of this study was to investigate whether splenectomy influences the tumor growth and metastatic pattern in an orthotopic syngeneic murine pancreatic cancer model. Murine pancreatic cancer cells (PAN02) were subcutaneously injected into the flanks of nude mice. A small tumor fragment (3 mm2), harvested from a subcutaneous tumor. was orthotopically implanted in the tail of the pancreas of C57/BL6 mice without splenectomy (control group, n=15) or with simultaneous splenectomy (splenectomy group, n=15). Tumor growth and metastatic patterns were analyzed by laparotomy at 21 days after surgery. No tumor growth was found in 5 mice (33.3%) of the control group and 1 mouse (6.7%) of the splenectomy group (p=0.169). Tumor volume was significantly larger in splenectomy group (p=0.013). Peritoneal seeding was more frequently observed in the splenectomy group (11 (73.3%) vs. 4 (26.7%), p=0.011). There were no differences in the number of liver and kidney metastasis between the two groups. The ratios of tumor-infiltrating CD4+ to FoxP3+ and CD8+ to FoxP3+ were significantly higher in the control group compared to the splenectomy group (8.2 +/- 9.3 vs. 2.4 +/- 1.5, p=0.046; 2.5 +/- 1.4 vs. 1.5 +/- 0.4, p=0.031, respectively). Splenectomy enhanced tumor growth and peritoneal seeding in an orthotopic syngeneic murine pancreatic cancer mouse model. The ramification of these results are discussed for pancreatic cancer treatment. PMID- 29179481 TI - Notochordal-cell derived extracellular vesicles exert regenerative effects on canine and human nucleus pulposus cells. AB - During intervertebral disc ageing, chondrocyte-like cells (CLCs) replace notochordal cells (NCs). NCs have been shown to induce regenerative effects in CLCs. Since vesicles released by NCs may be responsible for these effects, we characterized NC-derived extracellular vesicles (EVs) and determined their effect on CLCs. EVs were purified from porcine NC-conditioned medium (NCCM) through size exclusion chromatography, ultracentrifugation or density gradient centrifugation. Additionally, the EVs were quantitatively analyzed by high-resolution flow cytometry. The effect of NCCM-derived EVs was studied on canine and human CLC micro-aggregates in vitro and compared with NCCM-derived proteins and unfractionated NCCM. Porcine NCCM contained a considerable amount of EVs. NCCM derived EVs induced GAG deposition in canine CLCs to a comparable level as NCCM derived proteins and unfractionated NCCM, and increased the DNA and glycosaminoglycan (GAG) content of human micro-aggregates, although to a lesser extent than unfractionated NCCM. The biological EV effects were not considerably influenced by ultracentrifugation compared with size exclusion-based purification. Upon ultracentrifugation, interfering GAGs, but not collagens, were lost. Nonetheless, collagen type I or II supplemented to CLCs in a concentration as present in NCCM induced no anabolic effects. Porcine NCCM-derived EVs exerted anabolic effects comparable to NCCM-derived proteins, while unfractionated NCCM was more potent in human CLCs. GAGs and collagens appeared not to mediate the regenerative EV effects. Thus, NC-derived EVs have regenerative potential, and their effects may be influenced by the proteins present in NCCM. The optimal combination of NC-secreted factors needs to be determined to fully exploit the regenerative potential of NC-based technology. PMID- 29179480 TI - Neutrophil/lymphocyte ratio is a more sensitive systemic inflammatory response biomarker than platelet/lymphocyte ratio in the prognosis evaluation of unresectable pancreatic cancer. AB - Multiple cancers arise from sites of infection, chronic irritation, and inflammation. It has been widely accepted that pancreatic cancer is an inflammation-driven cancer. In this study, we investigated the application value of systemic inflammatory markers, neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR), in the prediction of chemotherapy response and prognosis in patients with late pancreatic cancer. 122 patients with inoperable pancreatic cancers were included and separated into two groups according to median values of NLR or PLR (NLR low:<3.81 or NLR high:>=3.81, and PLR low:<142.14 or PLR high>=142.14, respectively). Baseline NLR and PLR levels were significantly higher in pancreatic cancer patients compared with the healthy subjects. Neither of the baseline NLR or PLR levels could predict outcomes. Patients with low baseline level of NLR, but not PLR, had better responses to chemotherapy. Changes in NLR, but not PLR levels, were associated with the therapeutic efficacy. Patients who stayed in or dropped into the low NLR level subgroup after first-line chemotherapy had better responses, comparing to those stayed in or jumped into the high NLR level group. No similar results could be observed when the PLR level was investigated. Therefore, NLR is a more sensitive biomarker than PLR in the prediction of chemotherapy response of patients. PMID- 29179482 TI - Association of fibroblast growth factor receptor 1 gene amplification with poor survival in patients with esophageal squamous cell carcinoma. AB - Purpose: To investigate whether FGFR1 gene amplification is associated with clinicopathologic characteristics and its potential impact on survival in patients with resected esophageal squamous cell carcinoma (ESCC). Methods: Five hundred fifty-six ESCC patients undergoing curative resection of ESCC were retrospectively studied. FGFR1 gene copy number was determined in microarrayed tumor samples using fluorescent in situ hybridization (FISH) analysis. FGFR1 gene amplification status was prespecified as copy number >= 6 or FGFR1/CEN 8 ratio >= 2.2. FGFR1 expression was evaluated by immunohistochemistry. Overall survival (OS) and disease-free survival (DFS) were analyzed using the Kaplan-Meier method followed by the log rank test. Correlation with survival was examined using multivariate Cox regression. Results: FGFR1 amplification was identified in 67 (12.1%) patients; these patients had significantly shorter OS (50.0 vs 32.0 months; log rank; P<0.001) as well as shorter DFS (47.0 vs 28.0 months; log rank; P<0.001) than those without FGFR1 amplification. Under a Cox proportional hazard model, FGFR1 amplification was associated with significantly shorter OS (adjusted hazard ratio [AHR]=1.61; 95% CI, 1.10-2.43, P=0.004) and DFS (AHR=1.72; 95%CI, 1.15-2.48; P<0.001). Moreover, cases with high intratumoral FGFR1 expression showed significantly shorter OS and DFS than those with low FGFR1 expression. The frequency of FGFR1 amplification was significantly higher in heavy drinkers than in moderate and light drinkers. Conclusion: FGFR1 amplification is an independent adverse prognostic factor in surgically resected ESCC. FGFR1 may be a promising therapeutic target in patients with ESCC. PMID- 29179483 TI - MicroRNA-216a inhibits the metastasis of gastric cancer cells by targeting JAK2/STAT3-mediated EMT process. AB - MicroRNAs (miRNAs), a group of small, non-protein coding, endogenous RNAs, play critical roles in the tumorigenesis and progression of human cancer. miR-216a has recently been reported to play an oncogenic role in human cancer. While, the expression of miR-216a, its biological function and underlying molecular mechanisms in gastric cancer (GC) are largely unknown. In this study, we revealed that miR-216a was underexpressed in GC tissues compared to matched noncancerous tissues. Decreased levels of miR-216a were confirmed in GC cell lines compared with a normal gastric epithelium cell line. miR-216a underexpression was associated with malignant prognostic features including lymph node metastasis, venous infiltration, invasive depth and advanced TNM stage. GC patients with low miR-216a level showed an obvious shorter overall survival. miR-216a overexpression restrained migration and invasion of MGC-803 cells, while its knockdown exerted opposite effects on metastatic behaviors of SGC-7901 cells. In vivo experiments found that miR-216a restoration reduced metastatic nodes of GC cells in nude mice liver. miR-216a notably suppressed epithelial-mesenchymal transition (EMT) of GC cells. Janus kinase 2 (JAK2) was recognized as a direct target and downstream mediator of miR-216a in GC cells. Interestingly, JAK2/signal transducer and activator of transcription 3 (STAT3) pathway was prominently inactivated by miR-216a and probably mediated the role of miR-216a in the regulation of migration, invasion and EMT process of GC cells. In conclusion, these data suggest that miR-216a functions as a tumor suppressive miRNA in the development of GC possibly by targeting JAK2/STAT3-mediated EMT. PMID- 29179484 TI - Association of circulating branched-chain amino acids with cardiometabolic traits differs between adults and the oldest-old. AB - Branched-chain amino acids (BCAAs) are promising for their potential anti-aging effects. However, findings in adults suggest that circulating BCAAs are associated with cardiometabolic risk. Moreover, little information is available about how BCAAs influence clustered cardiometabolic traits in the oldest-old (>85 years), which are the fastest-growing segment of the population in developed countries. Here, we applied a targeted metabolomics approach to measure serum BCAAs in Chinese participants (aged 21-110 years) based on a longevity cohort. The differences of quantitative and dichotomous cardiometabolic traits were compared across BCAAs tertiles. A generalized additive model (GAM) was used to explore the dose-response relationship between BCAAs and the risk of metabolic syndrome (MetS). Overall, BCAAs were correlated with most of the examined cardiometabolic traits. The odds ratios for MetS across the increasing BCAA tertiles were 3.22 (1.70 - 6.12) and 5.27 (2.88 - 9.94, referenced to tertile 1) after adjusting for age and gender (Ptrend < 0.001). The association still existed after further controlling for lifestyle factors and inflammation factors. However, the correlations between circulating BCAAs and quantitative traits were weakened in the oldest-old, except for lipids, the levels of which were distinctly different from those in adults. The stratified analysis also suggested that the risky BCAAs-MetS association was more pronounced in adults than in the oldest-old. Moreover, generalized additive model (GAM)-based curve-fitting suggested that only when BCAAs exceeded a threshold (approximately 450 MUmol/L) was the BCAAs-MetS association significant. The relationship might be aging dependent and was more pronounced in adults than in the oldest-old. PMID- 29179485 TI - Cost-effectiveness analysis of fecal microbiota transplantation for inflammatory bowel disease. AB - There is a lack of health economics evidence on the use of fecal microbiota transplantation (FMT) for inflammatory bowel disease (IBD). This study aims to evaluate the cost-effectiveness before (with conventional therapy) and after introducing FMT for treating IBD. 104 patients with IBD received FMT were recruited. Health status was evaluated by European dimension health table (ED 5Q). Incremental cost-effectiveness ratio (ICER) and net monetary benefit (NB) were calculated by different age groups, genders, smoking status, and disease subtypes. The willingness-to-pay threshold was set to the value equal to three times China's per capita GDP (141240 CNY/QALY, 2014). From the health-care perspective, FMT strategy was 73% likely to be cost-effective compared with the conventional therapy before FMT with an ICER of -185712 CNY/QALY and a positive NB of CNY 45150. From the societal perspective, FMT strategy was 75% likely to be cost-effective with an ICER of -207417 CNY/QALY and a positive NB of CNY 48395. Moreover, younger patients (<= 24), females, non-smokers and Crohn's disease (CD) achieved more benefits. This study for the first time demonstrated that FMT showed its cost-effectiveness, especially on improving the life quality and decreasing the medical and societal cost, for the moderate to severe IBD in a Chinese cohort. PMID- 29179486 TI - Functional expression of Tim-3 on blasts and clinical impact of its ligand galectin-9 in myelodysplastic syndromes. AB - T-cell immunoglobulin mucin-3 (Tim-3), an inhibitory immune checkpoint receptor, is highly expressed on acute myeloid leukemia cells and its ligand galectin-9 is reported to drive leukemic progression by binding with Tim-3. However, it remains unclear whether the Tim-3-galectin-9 pathway is associated with the pathophysiology of myelodysplastic syndromes (MDS). Thus, we investigated the expression and function of Tim-3 and the clinical impact of its ligand galectin-9 in MDS. Tim-3 expression levels on MDS blasts by CD45/side-scatter or CD34/CD45 gating were increased as MDS progressed to the advanced stage. Tim-3 expression in the MDS blasts was upregulated in the presence of the cell culture supernatant of human stromal cells or the MDS-related cytokine transforming growth factor beta1. The proliferation of Tim-3+ MDS blasts was inhibited by the blockade of anti-Tim-3 antibody. Furthermore, plasma levels of galectin-9 were elevated as MDS progressed to the advanced stage in 70 MDS/acute leukemia transformed from MDS patients and was a prognostic factor in 40 MDS patients. Our data demonstrated that the Tim-3-galectin-9 pathway is associated with the pathogenesis and disease progression of MDS. These findings provide new insight into potential immunotherapy targeting the galectin-9-Tim-3 pathway in MDS. PMID- 29179487 TI - PARP-1 promotes tumor recurrence after warm ischemic liver graft transplantation via neutrophil recruitment and polarization. AB - Poly (ADP-ribose) polymerase 1 (PARP-1) is a crucial contributor to exacerbate ischemia and reperfusion (IR) injury and cancer process. However, there is little research into whether PARP-1 affects the hepatocellular carcinoma (HCC) recurrence after liver transplantation. In this study, we investigated the influence of PARP-1 on hepatic neutrophil mobilizing and phenotype shifting which may lead to HCC recurrence after liver transplantation. We found that rats received the grafts with warm ischemic injury had higher risk of HCC recurrence, which was markedly prevented by pharmacological inhibition of PARP-1 after liver transplantation. In mouse models, the up-regulation of PARP-1 was closely related to the greater tumor burden and increased hepatic susceptibility to recurrence after IR injury. The reason was that high hepatic PARP-1 led to increased liver CXCL1 levels, which in turn promoted recruitment of neutrophils. Both blocking CXCL1/CXCR2 signaling pathway and depleting neutrophils decreased tumor burden. Moreover, these infiltrating neutrophils were programmed to a proangiogenic phenotype under the influence of PARP-1 in vivo after hepatic IR injury. In conclusion, IR-induced PARP-1 up-regulation increased the hepatic recruitment of neutrophils through regulation of CXCL1/CXCR2 signaling and polarized hepatic neutrophils to proangiogenic phenotype, which further promoted HCC recurrence after transplantation. PMID- 29179488 TI - Forensic efficiency and genetic variation of 30 InDels in Vietnamese and Nigerian populations. AB - Insertion/deletion polymorphisms (InDels) are ubiquitous diallelic genetic markers that have drawn increasing attention from forensic researchers. Here, we investigated 30 InDel loci in Vietnamese and Nigerian populations and evaluated their usefulness in forensic genetics. The polymorphic information content of these populations ranged, respectively, from 0.164 to 0.375 and from 0.090 to 0.375 across loci. After Bonferroni correction, no significant deviation from Hardy-Weinberg equilibrium was found, except for HLD97 in the Nigerian population. The cumulative power of exclusion for all 30 loci in the Vietnamese and Nigerian populations was 0.9870 and 0.9676, respectively, indicating that this InDel set is not suitable for paternity testing in these populations, but could be included as a supplement. For the Vietnamese and the Nigerian populations, the mean observed heterozygosity was 0.5917 and 0.6268, and the combined discrimination power of the 30 loci was 0.9999999999767 and 0.9999999999603, respectively. These findings indicated that these InDels may be suitable for personal forensic identification in the studied populations. The results of DA distance, phylogenetic tree, principal component, and cluster analyses were consistent and indicated a clear pattern of regional distribution. Moreover, the Vietnamese population was shown to have close genetic relationships with the Guangdong Han and Shanghai Han populations. PMID- 29179489 TI - Saikosaponin A inhibits IL-1beta-induced inflammatory mediators in human osteoarthritis chondrocytes by activating LXRalpha. AB - Saikosaponin a (SSa), one of the main active components of Bupleurum falcatum, has been reported to have anti-inflammatory effect. In the present study, we investigated the anti-inflammatory effect of SSa on IL-1beta-stimulated human osteoarthritis chondrocytes. The cells were pretreated with SSa 12 h before IL 1beta treatment. The production of PGE2 and NO were detected by ELISA and Griess method. The levels of MMP1, MMP3, and MMP13 were measured by ELISA and qRT-PCR. The expression of NF-kappaB and LXRalpha were tested by western blot analysis. The results showed that SSa inhibited IL-1beta-induced PGE2 and NO production in a concentration-dependent manner. SSa also suppressed IL-1beta-induced MMP1, MMP3, and MMP13 production. Furthermore, SSa significantly attenuated IL-1beta induced phosphorylation levels of NF-kappaB p65 and IkappaBalpha. SSa also up regulated the expression of LXRalpha. The inhibition of SSa on PGE2, NO, MMP1, MMP3, and MMP13 production were reversed by LXRalpha siRNA or GGPP, the inhibitor of LXRalpha. In conclusion, our results demonstrated that SSa inhibited inflammatory responses in human chondrocytes in vitro. SSa might be a potential therapeutic drug for osteoarthritis. PMID- 29179490 TI - Proteome-based identification of apolipoprotein A-IV as an early diagnostic biomarker in liver fibrosis. AB - Hepatic fibrosis may ultimately result in organ failure and death, a reality compounded by the fact that most drugs for liver fibrosis appear to be effective only if given as a prophylactic or early treatment. In a dimethylnitrosamine induced liver fibrotic model, aspartate aminotransferase/alanine aminotransferase levels could not precisely distinguish the differences between the initial stage of liver fibrosis and normal control, whereas histological examination indicated that dimethylnitrosamine treatment for two weeks has resulted in hepatic fibrogenesis. Comprehensive proteomics identified 12 proteins mainly associated with the interleukin 6-stimulated inflammatory pathway. Coordinately, cytokine profiles showed that dimethylnitrosamine administration would stimulate various signaling pathways leading to liver fibrosis. Of note, apolipoprotein A4 in serum samples obtained from patients in the early stage of liver fibrosis were significantly increased compared to the healthy controls (p<0.001) while the area under curve was 0.966. Moreover, increased apolipoprotein A4 significantly enhanced transforming growth factor beta 1-induced alpha smooth muscle actin expression. In this regard, overexpression of apolipoprotein A4 in early stage of liver fibrosis might magnify and imply the progression of hepatic fibrosis. These findings suggest that apolipoprotein A4 upregulation may correlate with hepatic fibrosis staging and that apolipoprotein A4 together with current biomarker can increase the sensitivity and specificity for the early detection of liver fibrosis in a high-throughput manner.

AB - Suppression of tissue inhibitor of matrix metalloproteinase (TIMP) is associated with the tumor-like invasion of fibroblast-like synoviocytes (FLSs) that occurs during rheumatoid arthritis-related cartilage destruction. Silent information regulator 2 homolog1 (SIRT1), a histone deacetylase, is widely involved in transcriptional regulation, genomic stability, metabolism and DNA repair. Recent studies suggest that SIRT1 may also impact inflammatory response and the proliferation of FLSs in rheumatoid arthritis (RA). However, it is unknown whether SIRT1 has a role in the tumor-like invasion of FLSs in rheumatoid arthritis. Herein we report that SIRT1 contributes to FLS invasion and cartilage destruction via a TIMP1-dependent mechanism. Elevated SIRT1 in RA synovia suppresses TIMP1 expression via deacetylation of TIMP1-associated histones, thereby disrupting the binding of the transcription factor specificity protein 1 (Sp1) to the TIMP1 promoter. In rats with collagen-induced arthritis, depletion of SIRT1 remarkably promoted TIMP1 expression in synovial tissues and ameliorated cartilage destruction. These results describe a new role for SIRT1 and demonstrate its potential value as a therapeutic target for rheumatoid arthritis. PMID- 29179492 TI - Identification of a gene signature associated with radiotherapy and prognosis in gliomas. AB - Glioma is one of the most common primary brain tumors with poor prognosis. Although radiotherapy is an important treatment method for gliomas, the efficacy is still limited by the high occurrence of radioresistance and the underlying molecular mechanism is unclear. Here, we performed a data mining work based on four glioma expression datasets. These datasets were classified into training set and validation set. Radiotherapy-induced differential expressed genes and prognosis-associated genes were screened using different classifiers. The Kaplan Meier curves along with the two-sided Log Rank (Mantel-Cox) test were used to evaluate overall survival. We found the gene expression profiles of gliomas between those patients received radiotherapy and those patients without received radiotherapy were quite different. A 20-gene signature was identified, which was associated with radiotherapy.Furthermore, a novel 5-gene signature (HOXC10, LOC101928747, CYB561D2, RPL36A and RPS4XP2) as an independent predictor of glioma patients' prognosis was further derived from the 20-gene signature. These findings provided a new insight into the molecular mechanism of radioresistance in gliomas. The 5-gene signature might represent therapeutic target for gliomas. PMID- 29179493 TI - Sphingosine kinase 1 mediates diabetic renal fibrosis via NF-kappaB signaling pathway: involvement of CK2alpha. AB - Sphingosine kinase 1 (SphK1) plays a pivotal role in regulating diabetic renal fibrotic factors such as fibronectin (FN) and intercellular adhesion molecule-1 (ICAM-1). Especially, activation of SphK1 is closely linked to the body inflammatory reaction. Casein kinase 2alpha subunit (CK2alpha), a protein kinase related to inflammatory reaction, influences diabetic renal fibrosis and expressions of FN and ICAM-1 via NF-kappaB pathway. However, the mechanism by which SphK1 mediates diabetic renal fibrosis has not yet fully elucidated. The current study is aimed to investigate if SphK1 mediates diabetic renal fibrotic pathological process via inflammatory pathway and activation of CK2alpha. The following findings were observed: (1) Expressions of SphK1 were upregulated in kidneys of diabetic mice and rats; (2) Knockdown of SphK1 expression suppressed high glucose (HG)-induced NF-kappaB nuclear translocation and expressions of FN and ICAM-1; (3) Compared with C57 diabetic mice, SphK1-/- diabetic mice exhibited less renal fibrotic lesions, FN accumulation and NF-kappaB nuclear accumulation in glomeruli of kidneys; (4) SphK1 mediated phosphorylation of CK2alpha, while CK2alpha knockdown depressed SphK1-induced activation of NF-kappaB pathway. This study indicates the essential role of SphK1 in regulating activation of CK2alpha and diabetic renal fibrotic pathological process via NF-kappaB. PMID- 29179494 TI - Combinatorial effects of an epigenetic inhibitor and ionizing radiation contribute to targeted elimination of pancreatic cancer stem cell. AB - Pancreatic cancer is associated with a high mortality rate, owing to de novo and acquired drug resistance, thereby leading to highly invasive and metastatic pancreatic cancer cells. Therefore, targeting pancreatic cancer stem cells (CSCs) may be a novel therapeutic strategy for the treatment of pancreatic cancer. Here, we combined a DNA methylation inhibitor (5-aza-2'-deoxycytidine; 5-aza-dC) and ionizing radiation (IR) to improve anti-cancer effects by inhibiting growth and proliferation and promoting apoptosis of pancreatic cancer cells in vitro and in vivo. Importantly, the combinatorial effect of 5-aza-dC with IR on sphere-forming pancreatic cancer cells was preferentially targeted toward CSCs through the downregulation of regulatory factors of self-renewal and CSC surface markers. We next performed the RNA sequencing to understand the underlying cellular mechanisms of the combined treatment with IR and 5-aza-dC in pancreatic cancer cells. Global transcriptome profiling indicated that the expression of the Oct4 centered transcriptional network of genes was significantly downregulated in cells with combination treatment. Our data suggested that combination treatment with DNA methylation inhibitor and IR may be a novel therapeutic strategy for pancreatic cancer. Overall, these findings support the use of epigenetic therapy in combination with radiotherapy to improve therapeutic efficacy by targeting and eradicating pancreatic CSCs. PMID- 29179495 TI - ndmaSNF: cancer subtype discovery based on integrative framework assisted by network diffusion model. AB - Recently, with the rapid progress of high-throughput sequencing technology, diverse genomic data are easy to be obtained. To effectively exploit the value of those data, integrative methods are urgently needed. In this paper, based on SNF (Similarity Network Diffusion) [1], we proposed a new integrative method named ndmaSNF (network diffusion model assisted SNF), which can be used for cancer subtype discovery with the advantage of making use of somatic mutation data and other discrete data. Firstly, we incorporate network diffusion model on mutation data to make it smoothed and adaptive. Then, the mutation data along with other data types are utilized in the SNF framework by constructing patient-by-patient similarity networks for each data type. Finally, a fused patient network containing all the information from different input data types is obtained by using a nonlinear iterative method. The fused network can be used for cancer subtype discovery through the clustering algorithm. Experimental results on four cancer datasets showed that our ndmaSNF method can find subtypes with significant differences in the survival profile and other clinical features. PMID- 29179496 TI - Prognostic role of myoferlin expression in patients with clear cell renal cell carcinoma. AB - Objectives: In patients with cancer, myoferlin protein hyperexpression has been correlated with poor patient prognosis. Here, we evaluated myoferlin expression in patients with clear cell renal cell carcinoma (ccRCC) and investigated the prognostic significance of myoferlin expression in these patients. Materials and Methods: One hundred and fifty-two patients with ccRCC who underwent treatment at Gyeongsang National University Hospital, Korea, between January 2000 and December 2009 were enrolled. Immunohistochemical analysis was performed on tissue microarray blocks produced from surgical specimens. Surgical specimen cancerous cells were graded as showing myoferlin hyperexpression or hypoexpression by comparison with intratumoral endothelial cells. Disease-free survival was evaluated using Kaplan-Meier analysis. Cox regression analysis was used to determine the relationships between myoferlin expression levels, risk factors, and prognosis. Results: Seventy-one of 304 cores exhibited myoferlin hyperexpression. T stage was not associated with myoferlin hyperexpression, whereas a high Fuhrman nuclear grade was significantly associated with myoferlin hyperexpression. Kaplan-Meier analysis revealed that patients with T stage >2, Fuhrman nuclear grade >2, and those with myoferlin hyperexpression had poorer disease-free survival compared to those with lower T stage, lower Fuhrman nuclear grade, and myoferlin hypoexpression (all p <0.001). Furthermore, myoferlin hyperexpression was significantly associated with disease-free survival on Cox regression analysis (hazard ratio, 4.604; 95% confidence interval, 1.893-11.199; p = 0.001). Conclusion: Myoferlin expression could be a potential prognosticator in patients with ccRCC, and might be a useful marker for oncologic surveillance in such patients. PMID- 29179497 TI - Marital status and survival in epithelial ovarian cancer patients: a SEER-based study. AB - Marital status has been proved to be correlated to the survival of patients in various cancer types, except for that in the large female population of epithelial ovarian cancer (EOC). In this study, we retrospectively extracted 10905 eligible EOC patients from the Surveillance, Epidemiology, and End Results (SEER) database in the period from 2004 to 2012. We categorized marital status as married, divorced/separated, widowed, and never married. Chi-square test was used to investigate the association between marital status and other variables. The Kaplan-Meier test was adopted to compare survival curves of different groups. Multivariate Cox regression analyses were conducted to estimate the effect of marital status on overall survival (OS) and epithelial ovarian cancer-specific survival (EOCSS). To explore how marital status affected patients diagnosed at the same stage, we further performed subgroup analyses according to TNM stage. The results showed that marital status was an independent predictor for OS and EOCSS. Subgroup analyses indicated that the relationship between marital status and prognosis varied according to different conditions. Widowed patients had poorer prognosis than the other groups in most conditions, while the never married group showed similar risk of mortality as the married ones. PMID- 29179498 TI - ACAT-1 gene polymorphism is associated with increased susceptibility to coronary artery disease in Chinese Han population: a case-control study. AB - Several studies suggest an important role of Acyl-CoA: cholesterol acyltransferase-1(ACAT-1) in the development of atherosclerosis. The aim of present study was to investigate whether there exists a possible correlation between genetic variations in ACAT-1 genes and coronary artery disease (CAD) risk. Four polymorphisms (rs1044925, rs11545566, rs12121758 and rs10913733) were finally selected and genotyped in 750 CAD patients and 580 health controls, using the improved multiplex ligation detection reaction (iMLDR) method. We found that the rs11545566 G allele was associated with a significantly elevated CAD risk [GG vs. AA: adjusted odds ratio (AOR) = 1.62, 95% confidence interval (CI) = 1.13 2.32, P = 0.008; GA/GG vs. AA: AOR = 1.67, 95% CI = 1.22-2.29, P = 0.001]. The rs10913733 G allele was also associated with a significantly elevated CAD risk (GG vs. TT: AOR = 1.57, 95% CI = 1.08-2.28, P = 0.018; GT/GG vs. TT: AOR = 1.39, 95% CI = 1.07-1.79, P = 0.013). Multivariate linear regression analysis showed that the rs11545566 polymorphism was independently associated with the Gensini scores (P = 0.005). The Gensini score of subjects in the variant GG genotype group and the GG/GA genotype group were higher than the score of subjects in the AA genotype group (32.49 +/- 26.60 and 31.26 +/- 26.96 vs. 23.45 +/- 21.64; P = 0.001 and 0.002, respectively). Our results demonstrate that ACAT-1 rs1154556 and rs10913733 polymorphism are novel genetic factors in the development of CAD. Rs11545566 was also associated with the severity of CAD. PMID- 29179499 TI - Association between IL4, IL6 gene polymorphism and lumbar disc degeneration in Chinese population. AB - Lumbar disc disease (LDD) is a common musculoskeletal disorder, caused by degeneration of intervertebral discs of the lumbar spine and is one of the most common musculoskeletal disorders affliction in adult. There is growing evidence that LDD has strong genetic determinants. We analyze whether the IL4 and IL6 gene polymorphism is related to LDD in Chinese Han population. The participants were 498 with LDD and 463 without LDD. IL4 and IL6 gene polymorphism were determined by Sequenom MassARRAY. We found that SNPs rs1800796(OR = 1.29, 95% CI, 1.07 - 1.57, p = 0.009), rs1524107(OR = 1.28, 95% CI, 1.05 - 1.55, p = 0.013), rs2069840 (OR = 1.39, 95% CI, 1.03 - 1.89, p = 0.033) in IL6 gene were significantly associated with LDD risk at a 5% level. In addition, genetic models found IL4 gene (rs2243250) were associated with LDD. In this study, we analyzed and associated SNPs of IL4 and IL6 with LDD risk. In summary, four variations (rs1800796, rs1524107, rs2069840, rs2243250) of the selected candidate SNPs were associated with susceptibility to LDD in our study. The results of this study have the guiding significance in clinical work in the future in the treatment of lumbar disc herniation patients, not one-sided that the symptoms of low back pain only from mechanical oppression. PMID- 29179500 TI - hYSK1 promotes cancer cell proliferation and migration through negative regulation of p16INK4a under hypoxic conditions. AB - The alteration of expression of p16INK4a, a well-known cyclin-dependent kinase inhibitor involved in cell cycle control, in tumors is unclear, especially under hypoxic conditions. To evaluate p16INK4a regulation, we performed a protein microarray analysis. Among 1,800 proteins in the array, we identified hYSK1 as a novel protein that interacts with the tumor suppressor p16INK4a. hYSK1, a member of the Ste20 family of serine/threonine protein kinases, promotes cell migration and tumorigenesis and is activated by oxidative stress. However, the molecular mechanisms underlying the oncogenic potential of hYSK1 remain elusive. Here, we report that hYSK1 interacts with p16INK4a under hypoxic conditions in tumors, where it negatively regulates p16INK4a, enhancing cancer cell migration. Hypoxic stimulation of hYSK1 reduces p16INK4a accumulation through p16 promoter regulation to interact with unphosporylated SP-1 and increases matrix metalloproteinase-2 (MMP-2) expression by activating the MMP-2 promoter associated with cell migration and proliferation.Conversely, knocking down hYSK1 expression activated p16INK4a expression and suppressed MMP-2 expression. Thus, hYSK1 is necessary as a trigger for inactivating p16INK4a and activating MMP-2 during tumor migration, suggesting that hYSK1 is a specific negative regulator of the tumor suppressor p16INK4a and may represent a novel molecular target for reactivation of tumor suppressor genes in humans. PMID- 29179501 TI - The heterogeneous CTV-PTV margins should be given for different parts of tumors during tomotherapy. AB - Objective: The purpose of this study was to evaluate CTV-PTV margins of tumors for tomotherapy. Methods: Setup errors were analyzed for 151 patients receiving helical tomotherapy treatment. 53 patients had head and neck tumors, 45 had thoracic tumors, 20 had abdominal tumors, and 33 had pelvic tumors. The setup errors were calculated in six directions, i.e. +X (left), -X (right), +Y (head), Y (foot), +Z (ventral), and -Z (dorsal), after Megavoltage CT (MVCT) images were registered to simulation CT images. And then the CTV-PTV margins were calculated. Results: The setup errors along the +Z direction were significantly higher than that along the -Z direction (p<0.05). The CTV-PTV margins on +X, -X, +Y, -Y, +Z, and -Z directions were asymmetric for all tumors, and the heterogeneity were more remarkable on the +Z and -Z directions. The CTV-PTV margins on +Z and -Z were 4.1 mm, 4.6 mm, 5.2 mm, and 8.4 mm; and 3.9 mm, 7.7 mm, 3.3 mm, and 7.7 mm for head and neck tumors, thoracic tumors, abdominal tumors, and pelvic tumors, respectively. Conclusions: The CTV-PTV margins for patients with different types of tumors were heterogeneous during tomotherapy. The individual margins of six directions should be given for those patients who accept tomotherapy. PMID- 29179502 TI - What is the optimal radiation dose for non-operable esophageal cancer? Dissecting the evidence in a meta-analysis. AB - The standard radiation dose 50.4 Gy with concurrent chemotherapy for localized inoperable esophageal cancer as supported by INT-0123 trail is now being challenged since a radiation dose above 50 Gy has been successfully administered with an observable dose-response relationship and insignificant untoward effects. Therefore, to ascertain the treatment benefits of different radiation doses, we performed a meta-analysis with 18 relative publications. According to our findings, a dose between 50 and 70 Gy appears optimal and patients who received >= 60 Gy radiation had a significantly better prognosis (pooled HR = 0.78, P = 0.004) as compared with < 60 Gy, especially in Asian countries (pooled HR = 0.75, P = 0.003). However, contradictory results of treatment benefit for >= 60 Gy were observed in two studies from Western countries, and the pooled treatment benefit of >= 60 Gy radiation was inconclusive (pooled HR = 0.86, P = 0.64). There was a marginal benefit in locoregional control in those treated with high dose (> 50.4/51 Gy) radiation when compared with those treated with low dose (<= 50.4/51 Gy) radiation (pooled OR = 0.71, P = 0.06). Patients that received >= 60 Gy radiation had better locoregional control (OR = 0.29, P = 0.001), and for distant metastasis control, neither the > 50.4 Gy nor the >= 60 Gy treated group had any treatment benefit as compared to the groups that received <= 50.4 Gy and < 60 Gy group respectively. Taken together, a dose range of 50 to 70 Gy radiation with CCRT is recommended for non-operable EC patients. A dose of >= 60 Gy appears to be better in improving overall survival and locoregional control, especially in Asian countries, while the benefit of >= 60 Gy radiation in Western countries still remains controversial. PMID- 29179503 TI - Can polysaccharide K improve therapeutic efficacy and safety in gastrointestinal cancer? a systematic review and network meta-analysis. AB - Objective: To assess the comparative efficacy and safety of polysaccharide K (PSK), with or without chemotherapy, for patients with gastrointestinal cancer (GIC) through a systematic review and network meta-analysis. Materials and Methods: We performed a network meta-analysis to identify evidence from randomized controlled trials. We searched PubMed, Embase and the Cochrane Library for publications up to May 2017. The prespecified primary efficacy outcomes were 1-7 year overall survival (OS), while the secondary efficacy outcomes were 1-7 year disease-free survival (DFS); we performed subgroup analyses and meta regressions according to the cancer type (colorectal, esophagus and gastric cancer) and treatment arms (with or without chemotherapy). Safety outcomes were side effects of PSK. We conducted pairwise meta-analyses using a random-effects model and then performed random-effects network meta-analyses. Results: A total of 23 trials were eligible, involving 10684 patients and 13 intervention arms. PSK treatment significantly increased 1-5 year OS and resulted in positive trends in 6-7 year OS; significant increases were also found in 1-7 year DFS, while no increase in side effects was observed. Significant efficacy outcomes obvious in colorectal and gastric cancer groups, as well as PSK combined with chemotherapy groups (iv, po, iv+po). Network meta-analysis revealed that PSK combined with chemotherapy was superior, with significantly increased 3-year and 5-year OS. The study is registered with PROSPERO (CRD42017065193). Conclusions: The adjuvant immunochemotherapy agent PSK is effective and safe for patients with GIC. PSK combined with chemotherapy appears to be the preferred application of PSK. PMID- 29179504 TI - Risk factors associated with fatality of severe fever with thrombocytopenia syndrome: a meta-analysis. AB - Severe fever with thrombocytopenia syndrome is an emerging life-threatening infectious disease identified in 2009. Given high case-fatality rate among patients with severe fever with thrombocytopenia syndrome, identification of the risk factors at acute phase associated with fatality is crucial for treatment. Therefore, we aimed to meta-analytically evaluate risk factors of fatal clinical outcome of severe fever with thrombocytopenia syndrome. 238 fatal cases and 873 non-fatal cases from 12 studies were included in this meta-analysis. Elder age and high viral load were significantly associated with fatal clinical outcome. Further, severe fever with thrombocytopenia syndrome patients with fatal clinical outcome had significantly reduced level of albumin and platelet count, higher level of serum alanine aminotransferase, aspirate aminotransferase, lactic acid dehydrogenase and creatinine phosphokinase, and prolonged activated partial thromboplastin time, comparing with mild patients. These disturbed parameters function as predictors to warn fatal clinical outcome of the disease. Moreover, ribavirin has a minimal impact to alleviate disease progression of severe fever with thrombocytopenia syndrome. In conclusion, our finding demonstrates a panel of factors associated with fatality of SFTS disease, which have important implications during clinical practice. PMID- 29179506 TI - The diagnostic and prognostic value of CHFR hypermethylation in colorectal cancer, a meta-analysis and literature review. AB - The Checkpoint with Forkhead-associated and Ring finger domains (CHFR) is a mitotic checkpoint and tumor-suppressor gene, its loss contributes tumorigenesis of epithelial cancers including colorectal carcinoma (CRC). The diagnostic and prognostic value of CHFR promoter hypermethylation in CRC remains unclear. This study aimed to conduct a meta-analysis and literature review and investigate clinicopathological significance of CHFR promoter hypermethylation in CRC. The following online database were used: PubMed, EMBASE, and Web of Science up to March 2017. Odds Ratios (OR) and Hazard Ratios (HR) with 95% corresponding confidence intervals (CIs) were calculated. A total of seven relevant articles were available for meta-analysis which included 966 patients. The frequency of CHFR promoter hypermethylation significantly increased in CRC compared to normal colorectal mucosa tissue, pooled OR was 8.35, p < 0.00001. CHFR promoter hypermethylation was not significantly correlated to stage, OR was 1.16, p = 0.63. However, CHFR promoter hypermethylation was more frequently observed in CRC with positive lymph nodes metastasis than CRC with negative lymph nodes metastasis, OR was 0.46, p = 0.03. Additionally CHFR promoter hypermethylation was significantly related to poor overall survival in patients with CRC, HR was 0.62, p = 0.008. Based on these results, tumor CHFR promoter hypermethylation is not only a diagnostic biomarker for CRC, but also a prognostic marker. CHFR promoter hypermethylation is significantly associated with worse overall survival in patients with CRC. Our data suggested that CHFR could be a potential drug target for development of demethylation treatment for patients with CRC. PMID- 29179505 TI - MicroRNA-181 as a prognostic biomarker for survival in acute myeloid leukemia: a meta-analysis. AB - Accumulating evidence has indicated that microRNA-181 (miR-181) is dysregulated in hematological malignancies, and associates with the clinical outcomes. However, the association of miR-181 expression levels with acute myeloid leukemia (AML) remains inconclusive, as publications from different groups have reported contradictory results. In this manuscript, a meta-analysis was performed to assess the prognostic significance of miR-181 in AML patients. Eligible studies were retrieved from PubMed, Embase and Cochrane Library databases, and a total of 6 studies including 815 AML patients were included in the final analysis. Hazard ratios (HRs) and their corresponding 95% confidence intervals (CIs) were extracted and pooled to investigate the correlation between miR-181 and the survival of AML patients. Our results showed that elevated miR-181 expression was associated with increased survival in 395 American patients, and reduced survival in 325 Chinese patients. Both subgroup analyses and meta-regression indicated that the origin of AML patients contributed to the heterogeneity in the datasets evaluating the correlation between overall survival (OS) and miR-181. These results indicate that miR-181 can be used as a promising prognostic biomarker in AML patients, which may depend on the origin of patient population. PMID- 29179507 TI - Meta-analysis of the clinical value of abnormally expressed long non-coding RNAs for pancreatic cancer. AB - Pancreatic cancer (PC) is one of the most lethal malignant neoplasms of the digestive system. Long non-coding RNAs (lncRNAs) are a novel type of non-protein coding transcripts that play an important role in pancreatic carcinogenesis. We herein aimed to meta-analyze the diagnostic and prognostic significance of lncRNA expression profiles in PC. A comprehensive retrieval of eligible studies was performed based on the online databases. Quantitative meta-analyses of the pooled diagnostic parameters and hazard ratios (HRs) were enabled by using standard statistical methods. A total of 16 studies comprising 1386 PC patients were included. The pooled effect sizes exhibited that lncRNA expression profile achieved a combined sensitivity of 0.82 (95% CI: 0.72-0.89), specificity of 0.77 (95% CI: 0.65-0.86) and AUC (area under curve) of 0.87 (95% CI: 0.83-0.89) in distinguishing patients with PC from noncancerous controls. Notably, abnormally expressed lncRNAs were markedly associated with unfavorable overall survival (OS) in PC (univariate analysis: HR = 1.52, 95% CI: 1.04-2.22, P = 0.031; multivariate analysis: HR = 1.55, 95% CI: 1.19-2.02, P = 0.001). Statistical significance was also observed in our stratified analyses grouped by clinicopathologic features. In conclusion, abnormal lncRNA expression profiles could be rated as promising biomarker(s) to enable diagnosis and predict the prognosis of PC. PMID- 29179508 TI - Homeobox protein CDX2 as a prognostic biomarker in solid malignancies: a meta analysis. AB - Background: CDX2 is a caudal-homeobox gene and its expression is abnormal in numerous tumour cell types. Nevertheless, its prognostic value for solid tumours requires further investigation. Hence, we conducted a meta-analysis to determine the significance of CDX2 as a prognostic biomarker in solid malignancies systematically. Materials and Methods: We performed a systematic literature search in PUBMED and EMBASE up to May 2017. Retrospective studies comparing the prognostic value of different CDX2 levels in human malignancies were included. Data extractions and methodological assessments were performed separately by two investigators using a standard procedure. The statistical procedures were performed using Review Manager 5.3 and STATA/MP 14.0. Results: A total of 26 retrospective studies met the inclusion criteria and comprised 5008 participants. Patients with CDX2 overexpression had significantly better 3-year, 5-year, 10 year and disease-free survival outcomes in solid malignancies, regardless of the cancer type, mean age, and source region. Nevertheless, there was no significant difference in the patients from Europe. The expression level of CDX2 was not statistically associated with cancer relapse. Moreover, our analysis showed that CDX2 overexpression is correlated to better responses to chemotherapy in patients with TNM IV stage cancers. The stability of the pooled outcomes was verified by sensitivity analysis. The funnel plots, Egger's test and Begg's test jointly confirmed that there was no publication bias. Conclusions: Overexpression of CDX2 is a reliable biomarker of a better prognosis in solid malignancies. PMID- 29179509 TI - Benign and malignant breast lesions identification through the values derived from shear wave elastography: evidence for the meta-analysis. AB - Objective: The analysis was aimed to evaluate the diagnostic accuracy of shear wave elastography (SWE) for malignant breast lesions through a meta-analysis. Materials and Methods: Related articles were searched in databases of Pubmed, Embase and Cochrane library. Overall sensitivity and specificity were analyzed with DerSimonian and Laird random effects model. Area under curve (AUC) with corresponding 95% confidence interval were also analyzed to evaluate the diagnostic accuracy of SWE. P value < 0.05 predicted the significant heterogeneity between study. Sensitivity and publication bias were assessed as well. Results: According to the inclusion criteria, 25 articles were selected. In the subgroup analysis, diagnostic sensitivity and specificity of SWE in Asian population were 0.84 (0.79-0.88) and 0.87 (0.84-0.90), respectively, while they were 0.92 (0.86-0.96) and 0.89 (0.84-0.92) in Caucasian population. The diagnostic accuracy of SWE was a little higher for Caucasians than for Asians (0.95 vs. 0.92). The diagnostic sensitivity and specificity of virtual touch tissue quantification (VTTQ) were 0.85 (0.77-0.91) and 0.93 (0.88-0.96), respectively. It showed a little higher value in specificity and summary receiver operating curve (sROC) than that of SWE (0.93 vs. 0.87; 0.95 vs. 0.93). In addition, maximum stiffness exhibited higher detection sensitivity than that of mean stiffness (0.91 vs. 0.85). Conclusions: SWE serves as an accurate diagnostic technology for discriminating malignant and benign breast lesions. PMID- 29179510 TI - Targeting epigenetics for treatment of BRAF mutated metastatic melanoma with decitabine in combination with vemurafenib: A phase lb study. AB - Introduction: Epigenetic modifications play an important role in progression and development of resistance in V600EBRAF positive metastatic melanoma. Therefore, we hypothesized that the action of vemurafenib (BRAF inhibitor) can be made more effective by combining with low dose decitabine (a DNA methyltransferase inhibitor). The primary objective of this phase lb study was to determine the dose limiting toxicity and maximum tolerated dose of combination of subcutaneous decitabine with oral vemurafenib in patients with V600EBRAF positive metastatic melanoma with or without any prior treatment. Experimental Design: The study employed 3+3 dose escalation combining subcutaneous decitabine at different doses and schedules (4 cohorts) with the standard oral dose of vemurafenib 960 mg twice daily. Preclinical assessment and further analysis were also performed in A375 melanoma cell line. Results: Fourteen patients received study treatment. No dose limiting toxicity was encountered and maximum tolerated dose was not reached. Important toxicities included fatigue, increased creatinine, neutropenia, leucopenia, hypophosphatemia, rash and hyperuricemia. Three patients achieved complete response, three had partial response and five had stable disease. Preclinical assessment demonstrated action of the combination which delayed the development of acquired resistance and improved duration of treatment sensitivity. Conclusions: The combination of oral vemurafenib with subcutaneous decitabine is safe and showed activity in V600EBRAF positive metastatic melanoma. Since most responses were seen in cohort 1, which utilized low-dose, long-term decitabine, future studies of this combination treatment should utilize longer duration of decitabine, at the lowest dose of 0.1 mg/kg.

AB - Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been widely used for diagnosis and mediastinal lymph nodes staging in patients with suspicious lung cancer. Ultrasound elastography is a novel sonographical technique that can evaluate tissue compressibility. The aim of the present study was to investigate the diagnostic yield of elastography for differentiating malignant and benign mediastinal lymph nodes. Conventional EBUS B-mode features, including size, shape, border distinction, echogenicity, central hilar structure with central blood vessel and coagulation necrosis were also evaluated. The ultrasonic features were compared with the pathological results from EBUS-TBNA. 133 lymph nodes in 60 patients were assessed. Elastography displayed the highest area under the curve (AUC) (type 3 versus type 1: AUC, 0.825; 95% confidence interval [CI], 0.707-0.910) with an impressive sensitivity (100%) and an acceptable specificity (65%). The combined model covering the four positive criteria (elastography, heterogeneity, size, and shape) showed that the odds ratio for malignance is 9.44 with a 95% CI of 3.99 to 22.32 (p <0.0001). The combined model was superior to elastography alone (AUC, 0.851; sensitivity, 89.89%; specificity, 72.73%; p <0.0001). This prospective study showed that elastography is a feasible technique for classifying mediastinal lymph nodes, especially in combination with conventional EBUS imaging. PMID- 29179512 TI - Time to local recurrence as a predictor of survival in unrecetable gastric cancer patients after radical gastrectomy. AB - Local recurrence is common after radical surgery. However, the factors that contribute to survival after local recurrence remain unclear. In this retrospective study we analyzed the relationship between time to recurrence and survival after recurrence in 74 patients with locally recurrent gastric cancer. All patients received palliative radiotherapy with or without chemotherapy. The patients were divided into two groups according to the time between gastrectomy and local recurrence: early local recurrence (ELR, < 12 months after primary surgery), and late local recurrence (LLR, >=12 months after primary surgery). The median overall survival (OS) time was 15 months for patients with ELR and 25 months for LLR patients. Univariate and multivariate analysis revealed that time to local recurrence was significantly associated with OS after local recurrence (P = 0.001). The hazard ratio of ELR compared with LLR patients was 0.442 (95% confidence interval: 0.264-0.741). These results indicate that early local recurrence predicted poor prognosis in gastric cancer patients with unresectable local recurrence. PMID- 29179514 TI - Impact of preoperative diagnostic TURBT on progression-free survival in patients with pathological high-grade, stage T3/T4 bladder urothelial carcinoma. AB - Transurethral bladder tumor resection (TURBT) reportedly increases the circulating tumor cell count in patients with urothelial carcinoma of the bladder (UCB). To determine whether diagnostic TURBT leads to poorer progression-free survival (PFS) than diagnostic cystoscopic biopsy, we retrospectively reviewed the records of 96 consecutive primary pathological high-grade, stage T3/T4 UCB patients treated with radical cystectomy (RC) between January 2009 to December 2013. Clinicopathological features were collected from the medical records. PFS was determined from Kaplan-Meier curves, and potential independent prognostic factors for PFS were identified based on multivariable Cox analysis. During the follow-up period (median, 29 months), 43 patients experienced tumor progression (40 received diagnostic TURBT, 56 received cystoscopic biopsy). Patients who received cystoscopic biopsy had better PFS than those who received diagnostic TURBT (p = 0.008). Additionally, diagnostic TURBT was a significant risk factor for tumor metastasis in both univariable (HR: 2.219; 95% CI: 1.207-4.079; p = 0.010) and multivariable (HR: 2.455; 95% CI: 1.278-4.714; p = 0.007) Cox analyses. The present study provides the first evidence that diagnostic TURBT before RC negatively affects PFS in patients with pathological high-grade, stage T3/T4 UCB. PMID- 29179513 TI - The impacts of surgery of the primary cancer and radiotherapy on the survival of patients with metastatic rectal cancer. AB - The role of surgery of the primary cancer and radiation in metastatic colorectal cancer (mCRC) is still controversial currently, and evidence implied that colon cancer (CC) and rectal cancer (RC) should be treated with difference. Hence we focused on metastatic rectal cancer (mRC) solely to compare the cancer cause specific survival (CSS) of patients receiving varied treatments of the primary cancer: no treatment, surgery only, radiation only, and surgery plus radiation, based on the records of the Surveillance, Epidemiology, and End Results (SEER) database. A total of 8669 patients were included. Results demonstrated that the 2 year CSS was 28.1% for no treatment group, 30.7% for only radiation group, 50.2% for only surgery group, and 66.5% for surgery plus radiation group, reaching statistical difference (P < 0.001). Furthermore, the CSSs of mRC patients in the surgery group were similar regardless of resection ranges (P = 0.44). Besides, we analyzed the prognostic factors for mRC and found carcinoembryonic antigen (CEA) level, metastasis (M) stage, Tumor (T) stage, tumor size, differentiate grade, age and marital status should be taken into consideration when estimating the prognosis. Particularly, patients with normal CEA level or M1a stage showed a significant survival advantage. Overall, present study suggested that surgery of the primary cancer and radiation might help to improve the survival of mRC patients, especially when both treatments were conducted. Our results may assist clinicians to make better treatment strategy for patients with mRC. PMID- 29179515 TI - Characteristics, survival, and risk factors of Chinese young lung cancer patients: the experience from two institutions. AB - Limited data is available regarding lung cancer in Chinese young adults. This study was aimed to determine the characteristics, survival, and prognostic factors of young lung cancer patients in China. We reviewed demographic and clinical data, and survival information of 420 young patients (20-45 years old) diagnosed with lung cancer in two Chinese hospitals between 2000 and 2013. The results showed that lung cancer occurred more frequently (70%) and affected more males than females (43.8% vs 26.7%) in patients older than 36; whereas, more females were affected under age 35 (16.7% vs 12.8%). Most patients had adenocarcinoma (67.6%) and stage IV disease (72.4%) at presentation. The median survival of all young patients with lung cancer was 44 months (95% CI: 39-49), of which patients with stage I-IIIA disease had a longer survival than those with stage IIIB/IV disease (101 vs 22 months, p < 0.001). No significant difference in survival was found in patients having different histological subtypes or genders. Multivariate analysis revealed that high exposure risk occupations, smoking, family history of lung cancer were risk factors of young lung cancer patients. This study provides an overview of the clinical characteristics, patterns and prognostic factors of young patients with lung cancer in China. PMID- 29179516 TI - Lymph node ratio, but not the total number of examined lymph nodes or lymph node metastasis, is a predictor of overall survival for pancreatic neuroendocrine neoplasms after surgical resection. AB - Aim: To evaluate the prognostic significance of lymph node metastasis, extent of examined lymph nodes (ELNs) and lymph node ratio (LNR) for resected pancreatic neuroendocrine neoplasms (pNENs). Materials and Methods: Surgically resected pNENs were assimilated from the Surveillance, Epidemiology, and End Results database. Kaplan-Meier and Cox proportional hazard models were used to examine the prognostic effect of clinicopathological characteristics on overall survival; Harrell's concordance index was performed to assess the prognostic accuracy of all independent prognostic factors; and the Spearman's rank correlation was used to assess the correlation between LNR and other clinicopathological characteristics. Results: Totally, 1,273 pathologically confirmed pNENs were included in our study. The extent of ELNs failed to show any survival benefit in entire cohort (ELNs <= 12 vs. ELNs > 12, P = 0.072) or pNENs without lymph node metastasis (ELNs <= 28 vs. ELNs > 28, P = 0.108). Lymph node metastasis and LNR > 0.40 were significantly (both P < 0.001) adverse prognostic factors of overall survival. However, only LNR > 0.40 was the independent predictor of survival after adjusted for other clinicopathological characteristics. Besides LNR, the age, gender, primary tumor site, grade and stage also were the independent predictors of overall survival; and this survival model had an acceptable predictive power (Harrell's concordance index, 0.731). Conclusions: The current study suggested that the LNR, not the total number of ELNs and the lymph node metastasis, is an independent prognostic indicator of overall survival for pNENs after surgical resection. PMID- 29179517 TI - A phase I trial of NK-92 cells for refractory hematological malignancies relapsing after autologous hematopoietic cell transplantation shows safety and evidence of efficacy. AB - Background: Autologous NK cell therapy can treat a variety of malignancies, but is limited by patient-specific variations in potency and cell number expansion. In contrast, allogeneic NK cell lines can overcome many of these limitations. Cells from the permanent NK-92 line are constitutively activated, lack inhibitory receptors and appear to be safe based on two prior phase I trials. Materials and Methods: We conducted a single-center, non-randomized, non-blinded, open-label, Phase I dose-escalation trial of irradiated NK-92 cells in adults with refractory hematological malignancies who relapsed after autologous hematopoietic cell transplantation (AHCT). The objectives were to determine safety, feasibility and evidence of activity. Patients were treated at one of three dose levels (1 * 109 cells/m2, 3 * 109 cells/m2 and 5 * 109 cells/m2), given on day 1, 3 and 5 for a planned total of six monthly cycles. Results: Twelve patients with lymphoma or multiple myeloma who relapsed after AHCT for relapsed/refractory disease were enrolled in this trial. The treatment was well tolerated, with minor toxicities restricted to acute infusional events, including fever, chills, nausea and fatigue. Two patients achieved a complete response (Hodgkin lymphoma and multiple myeloma), two patients had minor responses and one had clinical improvement on the trial. Conclusions: Irradiated NK-92 cells can be administered at very high doses with minimal toxicity in patients with refractory blood cancers, who had relapsed after AHCT. We conclude that high dose NK-92 therapy is safe, shows some evidence of efficacy in patients with refractory blood cancers and warrants further clinical investigation. PMID- 29179518 TI - Reassessment of different criteria for diagnosing post-hepatectomy liver failure: a single-center study of 1683 hepatectomy. AB - Assessing the incidence and severity of post-hepatectomy liver failure (PHLF) can be based on different criteria, and we wished to compare the diagnostic efficiency and specificity of different PHLF criteria. Data from patients (n=1683) who received hepatectomies in the liver surgery department of Peking Union Medical College Hospital from April 2008 to August 2014 were retrospectively analyzed. Possible PHLF patients were screened according to the criteria of the International Study Group of Liver Surgery (ISGLS). Subsequently, other PHLF evaluation methods, including Child-Pugh score, "50-50" criteria, Model for End-Stage Liver Disease (MELD) score, and Clavien-Dindo classification were used to assess the suspected PHLF patients, and statistical analysis was performed for correlation of these methods with clinical prognoses. Using ISGLS grading, 40 cases (2.38%) were suspected to have PHLF, among whom 5 (0.30%) patients died. Of the 40 cases there were 9 patients of ISGLS grade A, 21 of grade B, and 10 of grade C. Among the entire group, Child-Pugh scoring showed 3 patients in grade A, 35 in grade B, and 2 in grade C, while only 5 patients met the "50-50" criteria. Interestingly, MELD scores >=11 points were found only in 3 cases. Twenty-eight patients were classified as Clavien-Dindo grade I, 8 as grade II, 3 as grade III, and 1 as grade IV. Prothrombin time on postoperative day 5 (PT5), ISGLS, and Clavien-Dindo were found to have significant correlation with the prognosis of PHLF (r>0.5, p <0.05), thus can be used as prognosis predictors for PHLF patients. PMID- 29179519 TI - Sleep in lonely heroin-dependent patients receiving methadone maintenance treatment: longer sleep latency, shorter sleep duration, lower sleep efficiency, and poorer sleep quality. AB - Given the socially isolated status of Chinese heroin-dependent patients (HDPs) and the significant association between loneliness and sleep problem in the general population, the impact of loneliness on sleep of HDPs is potentially substantial. The study aimed to test whether loneliness is associated with poor sleep in terms of quantity and quality in a consecutive sample of Chinese HDPs receiving methadone maintenance treatment (MMT). The study participants were 603 HDPs of three MMT clinics in Wuhan, China. Data on socio-demographic and clinical characteristics were collected by a standardized self-administered questionnaire. Sleep outcomes included sleep latency, sleep duration, sleep efficiency, and sleep quality. We measured depressive symptoms, loneliness, and sleep quality by using Zung's Self-rating Depression Scale, the single-item self-report of loneliness, and the Pittsburgh Sleep Quality Index, respectively. Multiple linear regression was used to examine whether loneliness is independently associated with sleep measures. After controlling for the confounding effects of potential socio-demographic and clinical variables, loneliness was significantly associated with longer sleep latency, shorter sleep duration, lower sleep efficiency, and poorer sleep quality. Loneliness may exacerbate sleep disturbance in Chinese HDPs of MMT clinics. Psychosocial interventions aimed at reducing loneliness in MMT clinics would improve the sleep of HDPs. PMID- 29179521 TI - Silibinin: an old drug for hematological disorders. AB - Introduction: Silibinin (silybin), a non-toxic natural polyphenolic flavonoid, is the principal and the most biologically active component of silymarin. It is efficient in the treatment of acute and chronic liver disorders caused by toxins, drug, alcohol, hepatitis, and gall bladder disorders. Further, in our previous studies, we explored the anti-cancer efficacy in common cancers, such as lung, prostatic, colon, breast, bladder, as well as, hepatocellular carcinoma. Interestingly, silibinin is still not solely limited to the treatment of these diseases. Recent research endeavors suggest that silibinin may function diversely and serve as a novel therapy for hematological disorders. Areas covered: It discovered several interesting viewpoints in the widely studied mechanisms of silibinin in the hematological disorders. Expert commentary: In this report, we review the up-to-date findings of more potency roles of silibinin in beta thalassemia (beta-TM), acute myeloid leukemia (AML), anaplastic large cell lymphoma (ALCL) and multiple myelomas (MM) therapy and attempt to clarify the mechanisms underlying its effects. There are two viewpoints: First, The functional mechanisms of silibinin in AML cells via regulating cell differentiation to exert anti-cancer effect; Second, combination treatment strategy may be a good choice. PMID- 29179520 TI - A comprehensive review of heregulins, HER3, and HER4 as potential therapeutic targets in cancer. AB - Heregulins (HRGs) bind to the receptors HER3 or HER4, induce receptor dimerization, and trigger downstream signaling that leads to tumor progression and resistance to targeted therapies. Increased expression of HRGs has been associated with worse clinical prognosis; therefore, attempts to block HRG dependent tumor growth have been pursued. This manuscript summarizes the function and signaling of HRGs and review the preclinical evidence of its involvement in carcinogenesis, prognosis, and treatment resistance in several malignancies such as colorectal cancer, non-small cell lung cancer, ovarian cancer, and breast cancer. Agents in preclinical development and clinical trials of novel therapeutics targeting HRG-dependent signaling are also discussed, including anti HER3 and -HER4 antibodies, anti-metalloproteinase agents, and HRG fusion proteins. Although several trials have indicated an acceptable safety profile, translating preclinical findings into clinical practice remains a challenge in this field, possibly due to the complexity of downstream signaling and patterns of HRG, HER3 and HER4 expression in different cancer subtypes. Improving patient selection through biomarkers and understanding the resistance mechanisms may translate into significant clinical benefits in the near future. PMID- 29179522 TI - Acetylation and deacetylation in cancer stem-like cells. AB - Cancer stem-like cell (CSC) model has been established to investigate the underlying mechanisms of tumor initiation and progression. The imbalance between acetylation and deacetylation of histone or non-histone proteins, one of the important epigenetic modification processes, is closely associated with a wide variety of diseases including cancer. Acetylation and deacetylation are involved in various stemness-related signal pathways and drive the regulation of self renewal and differentiation in normal developmental processes. Therefore, it is critical to explore their role in the maintenance of cancer stem-like cell traits. Here, we will review the extensive dysregulations of acetylation found in cancers and summarize their functional roles in sustaining CSC-like properties. Additionally, the use of deacetyltransferase inhibitors as an effective therapeutic strategy against CSCs is also discussed. PMID- 29179525 TI - Aliskiren therapy in hypertension and cardiovascular disease: a systematic review and a meta-analysis. AB - The efficacy and safety of aliskiren combination therapy with angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) in patients with hypertension and cardiovascular disease remains attractive attention. We searched the Cochrane Central Register, the Clinical Trials Registry, EMBASE, MEDLINE and PubMed for relevant literatures up to January 2017. A total of 13 randomized controlled trials (RCTs) with 12222 patients were included in this study, and the combined results indicated that aliskiren in combination therapy with ACEIs or ARBs had remarkable effects in reducing systolic blood pressure (SBP) [weighted mean differences (WMD), -4.20; 95% confidential intervals (CI) -5.44 to -2.97; I2 , 29.7%] and diastolic blood pressure (DBP: WMD, -2.09; 95% CI -2.90 to -1.27; I2 , 0%) when compared with ACEIs or ARBs monotherapy, but with significantly increased the risk of hyperkalaemia [relative risk (RR), 1.45; 95% CI 1.28 to 1.64; I2 ,10.6 %] and kidney injury ( RR, 1.92; 95% CI 1.14 to 3.21; I2 , 0%). Besides, there was no significant difference in the incidence of major cardiovascular events (RR, 0.95; 95% CI 0.89 to 1.02; I2 , 0%) between the combined therapy and ACEIs or ARBs monotherapy. In conclusion, this meta-analysis demonstrated that aliskiren in combination therapy with ACEs/ARBs could control BP effectively, but is associated with increasing risks of hyperkalaemia and kidney injury, and have no benefit in preventing of major cardiovascular events. PMID- 29179523 TI - Management of intracranial melanomas in the era of precision medicine. AB - Melanoma is the most lethal of skin cancers, in part because of its proclivity for rapid and distant metastasis. It is also potentially the most neurotropic cancer in terms of probability of CNS metastasis from the primary lesion. Despite surgical resection and radiotherapy, prognosis remains guarded for patients with brain metastases. Over the past five years, a new domain of personalized therapy has emerged for advanced melanoma patients with the introduction of BRAF and other MAP kinase pathway inhibitors, immunotherapy, and combinatory therapeutic strategies. By targeting critical cellular signaling pathways and unleashing the adaptive immune response against tumor antigens, a subset of melanoma patients have demonstrated remarkable responses to these treatments. Over time, acquired resistance to these modalities inexorably develops, providing new challenges to overcome. We review the rapidly evolving terrain for intracranial melanoma treatment, address likely and potential mechanisms of resistance, as well as evaluate promising future therapeutic approaches currently under clinical investigation. PMID- 29179524 TI - Predictors of hematoma expansion predictors after intracerebral hemorrhage. AB - Despite years of effort, intracerebral hemorrhage (ICH) remains the most devastating form of stroke with more than 40% 30-day mortality worldwide. Hematoma expansion (HE), which occurs in one third of ICH patients, is strongly predictive of worse prognosis and potentially preventable if high-risk patients were identified in the early phase of ICH. In this review, we summarize data from recent studies on HE prediction and classify those potential indicators into four categories: clinical (severity of consciousness disturbance; blood pressure; blood glucose at and after admission); laboratory (hematologic parameters of coagulation, inflammation and microvascular integrity status), radiographic (interval time from ICH onset; baseline volume, shape and density of hematoma; intraventricular hemorrhage; especially the spot sign and modified spot sign) and integrated predictors (9-point or 24-point clinical prediction algorithm and PREDICT A/B). We discuss those predictors' underlying pathophysiology in HE and present opportunities to develop future therapeutic strategies. PMID- 29179530 TI - Lamivudine: fading into the mists of time. PMID- 29179528 TI - Ischemic stroke in patients with POEMS syndrome: a case report and comprehensive analysis of literature. AB - Background: POEMS syndrome is a rare multi-systemic disease characterized by polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes. Arterial or venous thrombosis is a less-common complication of POEMS syndrome. Ischemic stroke has also been reported sporadically. However, the association between POEMS syndrome and ischemic stroke has not been entirely understood. Methods: A case of ischemic stroke caused by cerebral vasculitis in a patient with POEMS syndrome was presented. Then a comprehensive review and analysis of the literature were performed. Results: A total of 28 patients were identified. The common clinical manifestations of POEMS syndrome were rather non specific in patients with ischemic stroke compared with those of patients without ischemic stroke. Twenty patients were found with multiple ischemic lesions (71.5%). In the 25 patients who had undergone the evaluation of cerebral arteries, nineteen patients (76.0%) were found with cerebral vasculopathy. Twelve patients (48.0%) had more than one cerebral artery involved. Ischemic events were documented in 8 patients even when they were undergoing all the therapy for ischemic stroke. Ten (55.6%) of the 18 patients who had survival data died within two years after stroke events. Conclusion: Comprehensive analysis of literature revealed several trends in patients with ischemic stroke and POEMS syndrome including a low survival rate and a preponderance of cerebral vasculopathy and multiple cerebral arteries affected. Ischemic stroke may be a poor outcome predictor in patients with POEMS syndrome. Further researches focusing on a larger cohort may help in better characterizing and treating this rare complication of POEMS syndrome. PMID- 29179526 TI - Calcium influx and sperm-evoked calcium responses during oocyte maturation and egg activation. AB - Under the guidance and regulation of hormone signaling, large majority of mammalian oocytes go through twice cell cycle arrest-resumption prior to the fertilized egg splits: oocyte maturation and egg activation. Cytosolic free calcium elevations and endoplasmic reticulum calcium store alternations are actively involved in triggering the complex machineries and events during oogenesis. Among these, calcium influx had been implicated in the replenishment of endoplasmic reticulum store during oocyte maturation and calcium oscillation during egg activation. This process also drove successful fertilization and early embryo development. Store-operated Ca2+ entry, acts as the principal force of calcium influx, is composed of STIM1 and Orai1 on the plasma membrane. Besides, transient receptor potential channels also participate in the process of calcium inwards. In this review, we summarize the recent researches on the spatial temporal distribution of store-operated calcium entry components and transient receptor potential channels. Questions about how these channels play function for calcium influx and what impacts these channels have on oocytes are discussed. At the time of sperm-egg fusion, sperm-specific factor(s) diffuse and enable eggs to mount intracellular calcium oscillations. In this review, we also focus on the basic knowledge and the modes of action of the potential sperm factor phospholipase C zeta, as well as the downstream receptor, type 1 inositol 1,4,5 trisphosphate receptor. From the achievement in the previous several decades, it is easy to find that there are too many doubtful points in the field that need researchers take into consideration and take action in the future. PMID- 29179531 TI - Solvation of Amides in DMSO and CDCl3: An Attempt at Quantitative DFT-Based Interpretation of 1H and 13C NMR Chemical Shifts. AB - The study concerns N-methyl-2-pyrrolidinone, N,N-dimethylformamide, 2 pyrrolidinone, N-methylformamide, and formamide in DMSO-d6 and CDCl3 solutions. It has been shown that the results of DFT calculations [B3LYP and/or PBE0 6 311++G(2d,p), PCM] of molecular geometries and magnetic shielding are able to reproduce very well the amide 1H NMR and 13C NMR chemical shifts measured in these solvents provided that the specific solvation of the solute molecules and their association are taken into account and also that comparison of the experimental and theoretical data is carefully done. Analysis of the chemical shift data points out that in CDCl3 solutions primary and secondary amides are partially associated and that their carbonyl oxygen lone electron pairs are specifically solvated by solvent molecules. At the same time, association of the amides seems to be of minor importance in DMSO, while their N-H hydrogens form strong hydrogen bonds with solvent molecules. PMID- 29179527 TI - Hitting the nail on the head: combining oncolytic adenovirus-mediated virotherapy and immunomodulation for the treatment of glioma. AB - Glioblastoma is a highly aggressive malignant brain tumor with a poor prognosis and the median survival 14.6 months. Immunomodulatory proteins and oncolytic viruses represent two treatment approaches that have recently been developed for patients with glioblastoma that could extend patient survival and result in better treatment outcomes for patients with this disease. Together, these approaches could potentially augment the treatment efficacy and strength of these anti-tumor therapies. In addition to oncolytic activities, this combinatory approach introduces immunomodulation locally only where cancerous cells are present. This thereby results in the change of the tumor microenvironment from immune-suppressive to immune-vulnerable via activation of cytotoxic T cells or through the removal of glioma cells immune-suppressive capability. This review discusses the strengths and weaknesses of adenoviral oncolytic therapy, and highlights the genetic modifications that result in more effective and targeted viral agents. Additionally, the mechanism of action of immune-activating agents is described and the results of previous clinical trials utilizing these treatments in other solid tumors are reviewed. The feasibility, synergy, and limitations for treatments that combine these two approaches are outlined and areas for which more work is needed are considered. PMID- 29179532 TI - Induced Superaerophobicity onto a Non-superaerophobic Catalytic Surface for Enhanced Hydrogen Evolution Reaction. AB - Despite tremendous progress in the development of novel electrocatalysts for hydrogen evolution reaction (HER), the accumulation of hydrogen gas bubbles produced on the catalyst surface has been rather poorly addressed. The bubbles block the surface of the electrode, thus resulting in poor performance even when excellent electrocatalysts are used. In this study, we show that vertically grown graphene nanohills (VGNHs) possess an excellent capability to quickly disengage the produced hydrogen gas bubbles from the electrode surface, and thus exhibit superaerophobic properties. To compensate for the poor electrolytic properties of graphene toward HER, the graphene surface was modified with WS2 nanoparticles to accelerate the water-splitting process by using this hybrid catalyst (VGNHs-WS2). For comparison purposes, WS2 nanoparticles were also deposited on the flat graphene (FG) surface. Because of its superior superaerophobic properties, VGNHs WS2 outperformed FG-WS2 in terms of both catalytic activity toward the HER and superaerophobicity. Furthermore, VGNHs-WS2 exhibited a low onset potential (36 mV compared to 288 mV for FG-WS2) and long-term stability in the HER over an extended period of 20 h. This study provides an efficient way to utilize highly conductive and superaerophobic VGNHs as support materials for intrinsic semiconductors, such as WS2, to simultaneously achieve superaerophobicity and high catalytic activity. PMID- 29179533 TI - Missing Linker Defects in a Homochiral Metal-Organic Framework: Tuning the Chiral Separation Capacity. AB - Efficient chiral separation remains a very challenging task due to the identical physical and chemical properties of the enantiomers of a molecule. Enantiomers only behave differently from each other in the presence of other chiral species. Homochiral metal-organic frameworks (MOFs) have received much attention for their promising enantioseparation properties. However, there are still challenges to overcome in this field such as high enantiomeric separation. Structural defects play an important role in the properties of MOFs and can significantly change the pore architecture. In this work, we introduced missing linker defects into a homochiral metal-organic framework [Zn2(bdc)(l-lac)(dmf)] (ZnBLD; bdc = 1,4 benzenedicarboxylic acid, l-lac = l-lactic acid, dmf = N,N'-dimethylformamide) and observed an increase in enantiomeric excess for 1-phenylethanol of 35% with the defective frameworks. We adjusted the concentration of monocarboxylic acid ligand l-lactic acid by varying the ratio of Zn2+ to ligand from 0.5 to 0.85 mmol. Additionally, a defective framework was synthesized with propanoic acid as modulator. In order to elucidate the correlation between defects and enantiomeric excess, five characterization techniques (FTIR, TGA, 1H NMR, ICP, and PXRD) were employed. Full width at half-maximum analysis (fwhm) was performed on the powder X-ray diffraction traces and showed that the higher concentration of monocarboxylic acid MOFs were isostructural but suffered from increased fwhm values. PMID- 29179534 TI - Simultaneous Suppression of Metal Corrosion and Electrolyte Decomposition by Graphene Oxide Protective Coating in Magnesium-Ion Batteries: Toward a 4-V-Wide Potential Window. AB - Despite remarkable developments in electrolyte systems over the past 2 decades, magnesium-ion batteries still suffer from corrosion susceptibility and low anodic limits. Herein we describe how graphene oxide (GO), coated onto non-noble metals (Al, Cu, and stainless steel) via electrophoretic deposition, can solve this problem. In all phenyl complex electrolytes, GO coating results in a significant suppression of corrosion and extends the anodic limits (up to 4.0 V vs Mg/Mg2+) with no impact on reversible Mg plating/stripping reactions. The same effect of GO coating is also established in magnesium aluminum chloride complex electrolytes. This remarkable improvement is associated with the electrostatic interaction between the ionic charges of electrolytes and the surface-functional groups of GO. In addition, GO coating does not aggravate the cathode performance of Mo6S8, which allows the use of non-noble metals as current collectors. We also discuss the role of GO in increasing anodic limits when it is hybridized with alpha-MnO2. PMID- 29179535 TI - Differential Ion Mobility Separations in the Low-Pressure Regime. AB - Ion mobility spectrometry (IMS) in conjunction with mass spectrometry (MS) has emerged as a powerful platform for biological and environmental analyses. An inherent advantage of differential or field asymmetric waveform IMS (FAIMS) based on the derivative of mobility vs electric field over linear IMS based on absolute mobility is much greater orthogonality to MS. Effective coupling of linear IMS to MS and diverse IMS/MS arrangements and modalities impossible at ambient buffer gas pressure were enabled at much reduced pressures. In contrast, FAIMS devices operate at or near atmospheric pressure, which complicated integration with MS. Here, we show FAIMS at ~15-30 Torr using a planar-gap stage within the MS instrument envelope. Fields up to ~300 Td permitted by the Paschen law at these pressures greatly raise the separation speed, providing fair resolution in ~10 ms and FAIMS scans in under 5 s. Rapid separation and efficient ion collection at low pressure minimize losses in the FAIMS step. Separations for key analyte classes and their dependences on electric field mirror those at ambient pressure. The potential for proteomics is demonstrated by separations of isomeric peptides with variant localization of post-translational modifications. PMID- 29179536 TI - Carbon Nanotube Dispersion in Solvents and Polymer Solutions: Mechanisms, Assembly, and Preferences. AB - Debundling and dispersion of carbon nanotubes (CNTs) in polymer solutions play a major role in the preparation of carbon nanofibers due to early effects on interfacial ordering and mechanical properties. A roadblock toward ultrastrong fibers is the difficulty to achieve homogeneous dispersions of CNTs in polyacrylonitrile (PAN) and poly(methyl methacrylate) (PMMA) precursor solutions in solvents such as dimethyl sulfoxide (DMSO), N,N-dimethylacetamide (DMAc), and N,N-dimethylformamide (DMF). In this contribution, molecular dynamics simulations with accurate interatomic potentials for graphitic materials that include virtual pi electrons are reported to analyze the interaction of pristine single wall CNTs with the solvents and polymer solutions at 25 degrees C. The results explain the barriers toward dispersion of SWCNTs and quantify CNT-solvent, polymer-solvent, as well as CNT-polymer interactions in atomic detail. Debundling of CNTs is overall endothermic and unfavorable with dispersion energies of +20 to +30 mJ/m2 in the pure solvents, + 20 to +40 mJ/m2 in PAN solutions, and +20 to +60 mJ/m2 in PMMA solutions. Differences arise due to molecular geometry, polar, van der Waals, and CH-pi interactions. Among the pure solvents, DMF restricts CNT dispersion less due to the planar geometry and stronger van der Waals interactions. PAN and PMMA interact favorably with the pure solvents with dissolution energies of -0.7 to -1.1 kcal per mole monomer and -1.5 to -2.2 kcal per mole monomer, respectively. Adsorption of PMMA onto CNTs is stronger than that of PAN in all solvents as the molecular geometry enables more van der Waals contacts between alkyl groups and the CNT surface. Polar side groups in both polymers prefer interactions with the polar solvents. Higher polymer concentrations in solution lead to polymer aggregation via alkyl groups and reduce adsorption onto CNTs. PAN and PMMA solutions in DMSO and dilute solutions in DMF support CNT dispersion more than other combinations whereby the polymers significantly adsorb onto CNTs in DMSO solution. The observations by molecular simulations are consistent with available experimental data and solubility parameters and aid in the design of carbon nanofibers. The methods can be applied to other multiphase graphitic materials.

AB - Hydrated metal ions in the gas phase serve as model systems to investigate the impact of hydration on the chemistry of monovalent transition-metal centers. As a prototypical organometallic reaction involving electron transfer, the reactions of M(H2O)n+, M = V, Cr, Mn, Fe, Co, Ni, Cu, and Zn, n < 40, with C3H7I are studied by Fourier transform ion cyclotron resonance mass spectrometry. While no reaction was observed for vanadium, three different reactions were observed with the other metals, two of them involving the oxidation of the metal ion. Ligand exchange occurs for all metals except zinc. This reaction is sensitive to the size of the solvation shell and is observed predominantly for small cluster sizes. For Cr, Co, and Zn, the metal center is oxidized with formation of MI+ ions. The formation of [MC3H6(C3H7I)2]+, M = Co+, Ni+, proceeds most likely via oxidative addition of C3H7I to the metal ion via insertion into the C-I bond, followed by reductive elimination of HI. For Cu+, this reaction seems to stop after the insertion of the metal into the C-I bond, resulting in Cu(C3H7I)(H2O)n+. The reactions are compared with earlier studies on electron transfer involving hydrated metal centers.

AB - Covalent organic frameworks (COFs) have emerged as functional materials for various potential applications. However, the availability of three-dimensional (3D) COFs is still limited, and nearly all of them exhibit neutral porous skeletons. Here we report a general strategy to design porous positively charged 3D ionic COFs by incorporation of cationic monomers in the framework. The obtained 3D COFs are built of 3-fold interpenetrated diamond net and show impressive surface area and CO2 uptakes. The ion-exchange ability of 3D ionic COFs has been highlighted by reversible removal of nuclear waste model ions and excellent size-selective capture for anionic pollutants. This research thereby provides a new perspective to explore 3D COFs as a versatile type of ion-exchange materials.

AB - The catalytic cofactor of [FeFe]-hydrogenses (H-cluster) is composed of a generic cubane [4Fe-4S]-cluster (4FeH) linked to a binuclear iron-sulfur cluster (2FeH) that has an open coordination site at which the reversible conversion of protons to molecular hydrogen occurs. The (2FeH) subsite features a diatomic coordination sphere composed of three CO and two CN- ligands affecting its redox properties and providing excellent probes for FTIR spectroscopy. The CO stretch vibrations are very sensitive to the redox changes within the H-cluster occurring during the catalytic cycle, whereas the CN- signals seem to be relatively inert to these effects. This could be due to the more structural role of the CN- ligands tightly anchoring the (2FeH) unit to the protein environment through hydrogen bonding. In this work we explore the effects of structural changes within the secondary ligand sphere affecting the CN- ligands on FTIR spectroscopy and catalysis. By comparing the FTIR spectra of wild-type enzyme and two mutagenesis variants, we are able to assign the IR signals of the individual CN- ligands of the (2FeH) site for different redox states of the H-cluster. Moreover, protein film electrochemistry reveals that targeted manipulation of the secondary coordination sphere of the proximal CN- ligand (i.e., closest to the (4FeH) site) can affect the catalytic bias. These findings highlight the importance of the protein environment for re-adjusting the catalytic features of the H-cluster in individual enzymes and provide valuable information for the design of artificial hydrogenase mimics.

AB - A unified total synthesis of stemoamide-type alkaloids is reported. Our synthetic approach features the chemoselective convergent assembly of five-membered building blocks via stemoamide as the common precursor to tetracyclic natural products. The synthesis consists of two successive coupling reactions of the three five-membered building blocks. The first coupling reaction is the vinylogous Michael addition/reduction sequence, which enables the gram-scale synthesis of stemoamide. The second coupling reaction is a chemoselective nucleophilic addition to stemoamide. While the lactone-selective nucleophilic addition to stemoamide affords saxorumamide and isosaxorumamide, the lactam selective reductive nucleophilic addition leads to the formation of stemonine. Both chemoselective nucleophilic additions enable direct modification of stemoamide, resulting in highly concise and efficient total syntheses of the stemoamide-type alkaloids.

AB - In this work, 1H NMR relaxometry and diffusometry as well as viscometry experiments were carried out as a means to study the molecular dynamics of magnetic and nonmagnetic ionic liquid-based systems. In order to evaluate the effect of a cosolvent on the superparamagnetic properties observed for Aliquat iron-based magnetic ionic liquids, mixtures comprising different concentrations, 1% and 10% (v/v), of DMSO-d6 were prepared and studied. The results for both magnetic and nonmagnetic systems were consistently analyzed an suggest that, when at low concentrations, DMSO-d6 promotes more structured ionic arrangements, thus enhancing these superparamagnetic properties. Furthermore, the analysis of temperature and water concentration effects allowed to conclude that neither one of these variables significantly affected the superparamagnetic properties of the studied magnetic ionic liquids.

AB - Licorice, an important herbal medicine, is derived from the dried roots and rhizomes of Glycyrrhiza genus plants. It has been widely used in food, pharmaceutical, tobacco, and cosmetics industries with high economic value. However, overexploitation of licorice resources has severely destroyed the local ecology. Therefore, producing bioactive compounds of licorice through the biotransformation and bioengineering methods is a hot spot in recent years. In this perspective, we comprehensively summarize the biotransformation of licorice constituents into high-value-added derivatives by biocatalysts. Furthermore, successful cases and the strategies for de novo biosynthesizing compounds of licorice in microbes have been summarized. This paper will provide new insights for the further research of licorice.

AB - Microalgae were studied as function bioaccumulators of selenium (Se) for food and feed supplement. To investigate the bioaccumulation of Se and its effects on the unicellular green alga Chlorella pyrenoidosa, the algal growth curve, fluorescence parameters, antioxidant enzyme activity, and fatty acid and amino acid profiles were examined. We found that Se at low concentrations (<=40 mg L-1) positively promoted algal growth and inhibited lipid peroxidation and intracellular reactive oxygen species. The antioxidative effect was associated with an increase in the levels of glutathione peroxidase, catalase, linolenic acid, and photosynthetic pigments. Meanwhile, a significant increase in amino acid and organic Se content was also detected in the microalgae. In contrast, we found opposite effects in C. pyrenoidosa exposed to >60 mg L-1 Se. The antioxidation and toxicity appeared to be correlated with the bioaccumulation of excess Se. These results provide a better understanding of the effect of Se on green microalgae, which may help in the development of new technological applications for the production of Se-enriched biomass from microalgae.

AB - An H/D kinetic isotope effect (KIE) of 80 is found at -20 degrees C for the oxidation of 9,10-dihydroanthracene by [FeIV(O)(TMCS)]+, a complex supported by the tetramethylcyclam (TMC) macrocycle with a tethered thiolate. This KIE value approaches that previously predicted by DFT calculations. Other [FeIV(O)(TMC)(anion)] complexes exhibit values of 20, suggesting that the thiolate ligand of [FeIV(O)(TMCS)]+ plays a unique role in facilitating tunneling. Calculations show that tunneling is most enhanced (a) when the bond asymmetry between C-H bond breaking and O-H bond formation in the transition state is minimized, and (b) when the electrostatic interactions in the O---H---C moiety are maximal. These two factors-which peak for the best electron donor, the thiolate ligand-afford a slim and narrow barrier through which the H-atom can tunnel most effectively. PMID- 29179545 TI - Effect of Counterions on the Self-Assembly of Polystyrene-Polyphosphonium Block Copolymers. AB - The ability to manipulate block copolymers on the nanoscale has led to many scientific and technological advances. These include nanoscale ordered bulk and thin films and also solution phase components; these are promising materials for making smaller ordered electronics, selective membranes, and also biomedical applications. The ability to manipulate block copolymer material architectures on such small scales has risen from thorough investigations into the properties that affect the architectures. Polyelectrolytes are an important class of polymers that are used to make amphiphilic block copolymers. In this context the authors synthesized polystyrene-b-polyphosphonium block copolymers with different anions coordinated to the polyphosphonium block in order to study the effect of the anion on the aqueous self-assembly of the polymers. The anions play an important role in the solubility of the monomeric materials which results in differences in the self-assembly observed through dynamic light scattering and transmission electron microscopy. PMID- 29179546 TI - Reference Gene Selection and Prednisolone Target Gene Expression in Adipose Tissues of Friesian Cattle. AB - Corticosteroids are frequently used in livestock production, and their use is permitted by the European Union for therapeutic purposes only. However, small doses of corticosteroids are often administered in meat-producing animals to improve zootechnical performance. Prednisolone is one of the most commonly used corticosteroids with a growth-promoting purpose in animal husbandry. This study proposes to identify a gene whose expression is significantly regulated by prednisolone in visceral and subcutaneous adipose tissues. The analysis was conducted on Friesian cattle treated with prednisolone (30 mg day-1). The reference gene expression stability and optimal number for gene expression normalization were calculated. Family with sequence similarity 107 member A (FAM107A) and pyruvate dehydrogenase kinase 4 are the prednisolone target genes identified in adipose tissue. FAM107A was downregulated by ~2.9-fold by prednisolone in subcutaneous adipose tissue. This result suggests that FAM107A could be a possible indirect biomarker of prednisolone treatment in cattle and encourages a deeper investigation in this direction.

AB - This study presented the effects of alfalfa and calcium salts of long-chain fatty acids (CSFA) on feed intake, apparent digestibility, rumen fermentation, microbial community, plasma biochemical parameters, and fatty acid profile in Holstein freemartin heifers. Eight Holstein freemartin heifers were randomly divided into a 4 * 4 Latin Square experiment with 2 * 2 factorial diets, with or without alfalfa or CSFA. Dietary supplementation of CSFA significantly increased the apparent digestibility of dry matter, crude protein, neutral detergent fiber, organic matter, and significantly reduced N retention (P < 0.05). CSFA increased the concentration of ammonia nitrogen in the ruminal fluid (P < 0.05), but alfalfa increased the concentration of valerate and isovalerate (P < 0.05). CSFA increased the concentration of ammonia nitrogen and the relative population of Streptococcus bovis in the rumen (P < 0.05) and inhibited the relative population of Ruminococcus flavefaciens, methanogens, and protozoa (P < 0.05). Alfalfa instead of Leymus chinensis increased the relative population of Butyrivibrio fibrisolvens and Ruminobacter amylophilus in the rumen (P < 0.05) and reduced the relative population of the Ruminococcus albus and Megasphaera elsdenii (P < 0.05). Supplemental CSFA increased the concentration of cholesterol and low density lipoprotein cholesterol in the plasma (P < 0.05). And it also altered the composition of fatty acids in the plasma, which was expressed in reducing saturated fatty acid (SigmaSFA) ratio and C14-C17 fatty acids proportion except C16:0 (P < 0.05) and increasing the proportion of polyunsaturated fatty acid (SigmaPUFA) and unsaturated fatty acid (SigmaUFA) (P < 0.05). The results showed that alfalfa and CSFA had interaction effect on the apparent digestibility of ether extracts, plasma triglyceride concentration, isobutyrate concentration, and Ruminococcus albus relative abundance in the rumen. It was concluded that alfalfa substituting Leymus chinensis did not change the apparent digestibility of nutrients in the final stage of fattening Holstein freemartin heifers, while CSFA increased the cholesterol and the proportion of unsaturated fatty acids in plasma. Alfalfa and CSFA had mutual interaction effect on fat digestion and plasma triglycerides.

AB - Molecular iridium catalysts immobilized in metal-organic frameworks (MOFs) were positioned in the condensing chamber of a Soxhlet extractor for efficient CO2 hydrogenation. Droplets of hot water seeped through the MOF catalyst to create dynamic gas/liquid interfaces which maximize the contact of CO2, H2, H2O, and the catalyst to achieve a high turnover frequency of 410 h-1 under atmospheric pressure and at 85 degrees C. H/D kinetic isotope effect measurements and density functional theory calculations revealed concerted proton-hydride transfer in the rate-determining step of CO2 hydrogenation, which was difficult to unravel in homogeneous reactions due to base-catalyzed H/D exchange. PMID- 29179549 TI - Selective Hydrogen Isotope Separation via Breathing Transition in MIL-53(Al). AB - Breathing of MIL-53(Al), a flexible metal-organic framework (MOF), leads to dynamic changes as narrow pore (np) transitions to large pore (lp). During the flexible and reversible transition, the pore apertures are continuously adjusted, thus providing the tremendous opportunity to separate mixtures of similar-sized and similar-shaped molecules that require precise pore tuning. Herein, for the first time, we report a strategy for effectively separating hydrogen isotopes through the dynamic pore change during the breathing of MIL-53(Al), a representative of flexible MOFs. The experiment shows that the selectivity for D2 over H2 is strongly related to the state of the pore structure of MIL-53(Al). The highest selectivity (SD2/H2 = 13.6 at 40 K) was obtained by optimizing the exposure temperature, pressure, and time to systematically tune the pore state of MIL-53(Al). PMID- 29179550 TI - Quercetin Oxidation Paradoxically Enhances its Antioxidant and Cytoprotective Properties. AB - Quercetin oxidation is generally believed to ultimately result in the loss of its antioxidant properties. To test this assertion, quercetin oxidation was induced, and after each of its major metabolites was identified and isolated by HPLC-DAD ESI-MS/MS, the antioxidant (dichlorodihydrofluorescein oxidation-inhibiting) and cytoprotective (LDH leakage-preventing) properties were evaluated in Hs68 and Caco2 cells exposed to indomethacin. Compared to quercetin, the whole mixture of metabolites (QOX) displayed a 20-fold greater potency. After resolution of QOX into 12 major peaks, only one (peak 8), identified as 2,5,7,3',4'-pentahydroxy 3,4-flavandione or its 2-(3,4-dihydroxybenzoyl)-2,4,6-trihydroxy-3(2H) benzofuranone tautomer, could account for the antioxidant and cytoprotective effects afforded QOX. Peak 8 exerted such effects at a 50 nM concentration, revealing a potency 200-fold higher than that of quercetin. The effects of peak 8 were seen regardless of whether it was added to the cells 40 min before or simultaneously with the oxygen-reactive species-generating agent, suggesting an intracellular ability to trigger early antioxidant responses. Thus, the present study is the first to reveal that in regard to the intracellular actions of quercetin, attention should be extended toward some of its oxidation products.

AB - Strigolactones are plant hormones regulating essential stages of a plant's development. Their low natural abundance combined with a low chemical stability significantly hampered the detailed investigation of their biological activity. Noncanonical strigolactones lack the fused tricyclic ABC-ring system commonly present in canonical-type strigolactones but feature an open-chain unit linking structurally diverse A-ring moieties to the butenolide D-ring. We herein present an efficient synthetic access to enantiomerically pure noncanonical strigolactones by a Stille cross-coupling approach to forge the central diene moiety and demonstrate this strategy by syntheses of natural products methyl carlactonoate and carlactonic acid. Furthermore, a synthetic access to deuterium labeled analogues of these natural products has been developed. PMID- 29179552 TI - Universal Method for Creating Hierarchical Wrinkles on Thin-Film Surfaces. AB - One of the most interesting topics in physical science and materials science is the creation of complex wrinkled structures on thin-film surfaces because of their several advantages of high surface area, localized strain, and stress tolerance. In this study, a significant step was taken toward solving limitations imposed by the fabrication of previous artificial wrinkles. A universal method for preparing hierarchical three-dimensional wrinkle structures of thin films on a multiple scale (e.g., nanometers to micrometers) by sequential wrinkling with different skin layers was developed. Notably, this method was not limited to specific materials, and it was applicable to fabricating hierarchical wrinkles on all of the thin-film surfaces tested thus far, including those of metals, two dimensional and one-dimensional materials, and polymers. The hierarchical wrinkles with multiscale structures were prepared by sequential wrinkling, in which a sacrificial layer was used as the additional skin layer between sequences. For example, a hierarchical MoS2 wrinkle exhibited highly enhanced catalytic behavior because of the superaerophobicity and effective surface area, which are related to topological effects. As the developed method can be adopted to a majority of thin films, it is thought to be a universal method for enhancing the physical properties of various materials. PMID- 29179553 TI - How Interatomic Steps in the Exact Kohn-Sham Potential Relate to Derivative Discontinuities of the Energy. AB - Accurate density functional calculations hinge on reliable approximations to the unknown exchange-correlation (xc) potential. The most popular approximations usually lack features of the exact xc potential that are important for an accurate prediction of the fundamental gap and the distribution of charge in complex systems. Two principal features in this regard are the spatially uniform shift in the potential, as the number of electrons infinitesimally surpasses an integer, and the spatial steps that form, for example, between the atoms of stretched molecules. Although both aforementioned concepts are well known, the exact relationship between them remained unclear. Here we establish this relationship via an analytical derivation. We support our result by numerically solving the many-electron Schrodinger equation to extract the exact Kohn-Sham potential and directly observe its features. Spatial steps in the exact xc potential of a full configuration-interaction (FCI) calculation of a molecule are presented in three dimensions.

AB - A comparison between experimental and Broken Symmetry Density Functional theory (BS-DFT) calculated hyperfine couplings for the S2 state of the oxygen-evolving complex (OEC) has been performed. The effect of Ca substitution by Sr combined with the protonation state of two terminal hydroxo or aqua ligands, W1 and W2, on the calculated hyperfine couplings of 55Mn, 13C, 14N, 17O, and 1H nuclei has been investigated. Our findings show best agreement with experiment for OEC models which contain a hydroxide group at the W2 position and a water molecule at W1. For this model the agreement between calculated and experimental data for all hyperfine couplings is excellent. Models with a hydroxide group at W1 are particularly poor models. Sr substitution has a minor influence on calculated hyperfine couplings in agreement with experimental determinations. The sensitivity of the hyperfine couplings to relatively minor changes in the OEC structure demonstrates the power of this methodology in refining the details of its steric and electronic structure which is an essential step in formulating a complete mechanism for water oxidation by the OEC.

AB - A group of toxic aldehydes such as, malondialdehyde (MDA), 4-hydroxy-2-hexenal (HHE), and 4-hydroxy-2-nonenal (HNE) have been found in various vegetable oils and oil-based foods. Then simultaneous determination of them holds a great need in both the oil chemistry field and food field. In the present study, a simple and efficient analytical method was successfully developed for the simultaneous separation and detection of MDA, HHE, and HNE in vegetable oils by reversed-phase high-performance liquid chromatography (RP-HPLC) coupled with photodiode array detector (PAD) at dual-channel detection mode. The effect of various experimental factors on the extraction performance, such as coextraction solvent system, butylated hydroxytoluene addition, and trichloroacetic acid addition were systematically investigated. Results showed that the linear ranges were 0.02 10.00 MUg/mL for MDA, 0.02-4.00 MUg/mL for HHE, and 0.03-4.00 MUg/mL for HNE with the satisfactory correlation coefficient of >0.999 for all detected aldehydes. The limit of detection (LOD) and limit of quantification (LOQ) of MDA, HHE, and HNE were ~0.021and 0.020 MUg/mL, ~0.009 and 0.020 MUg/mL, and ~0.014 and 0.030 MUg/mL, respectively. Their recoveries were 99.64-102.18%, 102.34-104.61%, and 98.87-103.04% for rapeseed oil and 96.38-98.05%, 96.19-101.34%, and 96.86-99.04% for French fries, separately. Under the selected conditions, the developed methods was successfully applied to the simultaneous determination of MDA, HHE, and HNE in different tested vegetable oils. The results indicated that this method could be employed for the quality assessment of vegetable oils. PMID- 29179556 TI - Long-Range Changes in Neurolysin Dynamics Upon Inhibitor Binding. AB - Crystal structures of neurolysin, a zinc metallopeptidase, do not show a significant conformational change upon the binding of an allosteric inhibitor. Neurolysin has a deep channel where it hydrolyzes a short neuropeptide neurotensin to create inactive fragments and thus controls its level in the tissue. Neurolysin is of interest as a therapeutic target since changes in neurotensin level have been implicated in cardiovascular disorders, neurological disorders, and cancer, and inhibitors of neurolysin have been developed. An understanding of the dynamical and structural differences between apo and inhibitor-bound neurolysin will aid in further design of potent inhibitors and activators. For this purpose, we performed several molecular dynamics (MD) simulations for both apo and inhibitor-bound neurolysin. A machine learning method (Linear Discriminant Analysis) is applied to reveal differences between the apo and inhibitor-bound ensembles in an automated way, and large differences are observed on residues that are far from both the active site and the inhibitor binding site. The effects of inhibitor binding on the collective motions of neurolysin are extensively analyzed and compared using both Principal Component Analysis and Elastic Network Model calculations. We find that inhibitor binding induces additional low-frequency motions that are not observed in the apo form. ENM also reveals changes in inter- and intradomain communication upon binding. Furthermore, differences are observed in the inhibitor-bound neurolysin contact network that are far from the active site, revealing long-range allosteric behavior. This study also provides insight into the allosteric modulation of other neuropeptidases with similar folds. PMID- 29179557 TI - Displacement of Bax by BMF Mediates STARD13 3'UTR-Induced Breast Cancer Cells Apoptosis in an miRNA-Depedent Manner. AB - The balance of pro- and antiapoptotic gene expression programs dominates the apoptotic progress of cancer cells. We previously demonstrated that STARD13 3'UTR suppressed breast cancer metastasis via inhibiting epithelial-mesenchymal transition (EMT). However, the roles of STARD13 3'UTR in breast cancer apoptosis remain elusive. Here, we identified that STARD13 3'UTR promoted cell apoptosis in vitro and in vivo. Mechanistically, STARD13 3'UTR acted as a ceRNA for BMF (Bcl-2 modifying factor), thus increasing BMF expression in an miRNA-dependent manner. Meanwhile, STARD13 3'UTR enhanced the interaction of BMF/Bcl-2 to release Bax (Bcl-2 associated X protein) in breast cancer cells. Finally, we verified the ceRNA relationship between STARD13 and BMF in vivo. Collectively, these findings suggest that STARD13 3'UTR could act as a ceRNA for BMF to promote apoptosis and recognize STARD13 3'UTR as a potential therapeutic target in breast cancer cells. PMID- 29179558 TI - Physicochemical characteristics of the Lasiococca comberi Haines seeds. AB - Physicochemical characteristics and fatty acid composition of Lasiococca comberi Haines (Euphorbiaceae), an endangered forest tree species, were determined for the first time. The oil, protein, crude fibre and carbohydrate contents in seeds were 41.5, 13.8, 22.2 and 11.6%, respectively. The refractive index, pH, specific gravity, saponification value, iodine value, peroxide value and p-anisidine value of seed oil were 1.4781, 6.4, 0.9, 178.4 mg KOH/g, 196 g I2/100 g of oil, 5.1 mEq O2/kg and 188.4, respectively. The predominant fatty acids were linolenic acid (65.3%), oleic acid (13.8%), linoleic acid (7.1%) and palmitic acid (5.3%). HPLC analysis revealed the presence of alpha-tocopherol (13.2 mg/100 g) and gamma tocopherol (6.3 mg/100 g) as the major tocopherols. The results indicated that L. comberi seed oil can be classified as drying oil having possible applications in different industries and as an important dietary source of omega-3 fatty acids. PMID- 29179559 TI - Does Exercise During Pregnancy Affect Placental Weight?: A Randomized Clinical Trial. AB - Placental weight (PW) is a measure commonly used to summarize growth and aspects of placental function. In a normal pregnancy, it is reasonable to assume that PW is related to aspects of the functional capacity of the placenta. The placenta, as the site for all maternal-fetal oxygen and nutrient exchange, influences birth weight and is thus central to a successful pregnancy outcome. PW is the most common way to characterize placental growth, which relates to placental function. With physical exercise becoming an integral part of life for many women, the question of whether exercise during pregnancy has an adverse effect on the growing fetus is very important. The aim was to examine the influence of an aerobic exercise program throughout pregnancy on PW among healthy pregnant women. A randomized control trial was used (registration trial number: NCT02420288). Women were randomized into an exercise group (EG; n = 33) or a control group (CG; n = 32) that received standard care. The EG trained 3 days/week (55-60 min/session) from gestational Weeks 9-11 until Weeks 38-39. The 85 training sessions involved aerobic, muscular and pelvic floor strength, and flexibility exercises. PW and other pregnancy outcomes were measured. There was high attendance to the exercise program, and no differences in the PW at delivery were observed between study groups (CG = 493.2 +/- 119.6 g vs. EG = 495.4 +/- 150 g, p = .95). A regular, supervised exercise program throughout pregnancy does not affect the PW in healthy pregnant women. PMID- 29179560 TI - The Association Between Hospital Characteristics and Nonresponse in Organization Survey: An Analysis of the National Healthcare Establishment and Workforce Survey in Malaysia. AB - In any survey where some of the invited participants fail to respond estimates may be biased. The literature on survey nonresponse is substantial, and the intellectual focus has typically been on the nonresponse of individuals. An important yet less scrutinized area in the analysis of nonresponse is in organizational surveys, particularly surveys of health-care organizations. This study used data from the 2010 National Healthcare Establishment and Workforce Survey in Malaysia to examine the relationship between a set of measurable hospital attributes and their probability of survey response and the relationship between this probability and the differences in survey estimates. We found that readily measurable hospital characteristics such as size and geographical location are useful predictors of survey response likelihood. Larger hospitals and hospitals located in less developed geographical regions responded more favorably than their counterparts. We have also illustrated that the resulting response pattern affected some key survey estimates. These findings have the potential to extend our understanding of nonresponse to organization surveys in the health-care sector, potentially allow for the prediction of nonresponse, and help researchers to identify profiles of "reluctant responders" before a survey commences, so that additional engagement strategies may be used. PMID- 29179561 TI - Development and Validation of the Activities of Daily Living Short Form for Community-Dwelling Korean Stroke Survivors. AB - This study developed and validated a short form (SF) using activities of daily living (ADL) outcome measures from the Korea National Health and Nutrition Examination Survey (KNHANES) that can minimize survey administration burden for clinicians. This study utilized secondary data from the 2005 KNHANES with 422 community-dwelling stroke survivors. The KNHANES data were collected from April to June 2005 in South Korea. We created a 7-item SF from the 17 ADL questions in the survey using item response theory (IRT) methodologies. The precision and validity of the SF were compared to the full questionnaire of ADL items and the EuroQol-5D total score. Among the 17 ADL questions, 14 questions demonstrated unidimensional construct validity. Using IRT methodologies, a set of 7 items were selected from the full bank. The 7-item SF demonstrated good psychometric properties: high correlation with the full bank ( r = .975, p < .001), good internal consistency (Cronbach's alpha = .93), and a high correlation with the EuroQol-5D total score ( r = .678, p < .001). These findings indicate that a well developed SF can precisely measure ADL performance capacity for stroke survivors compared to the full item bank, which is expected to reduce the administration burden of the KNHANES.

A randomized, single-blind experimental design was used. Participants were recruited from maternity wards of one medical center in Taiwan. The control group ( n = 103) received routine nursing care, and intervention group ( n = 140) received interventional support during hospitalization. The Beck Anxiety Inventory, Edinburgh Postnatal Depression Scale, and Quality of Life Enjoyment and Satisfaction Questionnaire were used at admission and 2 weeks of hospitalization. For the control group, anxiety and depression scores increased significantly and quality of life decreased 2 weeks after hospitalization. Participants who received 2 weeks of support intervention had significantly lower anxiety and depression scores than controls. Thus, clinical nurses can offer support interventions to improve anxiety and depression for women with preterm labor during hospitalization. PMID- 29179563 TI - Clinical Outcomes for Cystinuria Patients with Unilateral Versus Bilateral Cystine Stone Disease. AB - INTRODUCTION: Cystinuria is a genetic disorder marked by elevated urinary cystine excretion and recurrent cystine nephrolithiasis. Interestingly, despite seemingly similar contralateral renal anatomy, a subset of cystinuric patients consistently form stones in only one kidney. The aim of this study is to evaluate clinical outcomes in unilateral vs bilateral cystine stone formers. PATIENTS AND METHODS: We performed a retrospective case-control study of cystinuric patients evaluated and treated at the University of California, San Francisco between 1994 and 2015 and categorized patients as either unilateral or bilateral stone formers. Clinical presentation, baseline patient demographics, stone procedures, medical therapy regimens, and long-term renal function were compared between the two groups. RESULTS: A total of 42 cystine stone patients (22 female, 20 male) were included in the analysis. The median age at first presentation was 18.5 years and median age at study conclusion was 45.5 years. Two-thirds of patients (n = 28) had a history of bilateral stones, whereas one-third (n = 14) had unilateral stones. Medical therapy regimens were similar between groups. Despite an increased average number of lifetime surgeries (7.5 sessions for bilateral vs 3.7 sessions for unilateral, p < 0.05), there was no significant difference in medians of the most recent glomerular filtration rate when compared with unilateral stone formers (81.5 vs 95 mL/min, respectively; p = 0.28). CONCLUSIONS: The majority of cystinuric patients within our cohort form stones bilaterally during their lifetime, and require more surgical interventions than unilateral stone formers. Despite this, overall renal function is well preserved in unilateral and bilateral cystinuric stone formers treated with minimally invasive stone extraction procedures.

AB - Hyssopus seravshanicus (Dubj.) Pazij has been used as traditional herb and food due to its wide biological properties. Seventeen known compounds were isolated from the ethyl acetate fraction. Their structures were identified by spectroscopic data and comparison with published data. Among them, 14 ones were identified from H. seravshanicus for the first time. DPPH and ABTS radical scavenging activities for crude ethanol extract (CEE), ethyl acetate fraction (EAF), butanol fraction (BF) and compounds 1, 3, 8, 10, 11 and 13 were performed. CEE, compounds 1, 3, 11 and 13 exhibited potent antioxidant activities. Compound 1 was found to increase the melanin content and tyrosinase activity of B16 melanoma cells. Moreover, the quantitative estimation of compound 1 in the ethyl acetate fraction was carried out by UPLC-DAD and the method was validated. This is the first report on the isolation and bioactivity research on the non-valotile components of H. seravshanicus. PMID- 29179565 TI - American Urological Association Antibiotic Best Practice Statement and Ureteroscopy: Does Antibiotic Stewardship Help? AB - PURPOSE: To determine compliance with the American Urological Association (AUA) antimicrobial prophylaxis best practice statement and whether the use of postoperative antibiotics is associated with lower rates of postoperative urinary tract infection (UTI) in patients with nephroureterolithiasis and a negative preoperative urine culture undergoing ureteroscopy. MATERIALS AND METHODS: A retrospective review of all adult patients undergoing ureteroscopy from 2013 to 2014 for stone disease with a negative preoperative urine was conducted. Patients who did and did not receive postoperative oral antibiotics beyond 24 hours of surgery were identified. The rates of culture-proven postoperative UTI and unplanned postoperative encounters were determined for both groups. Between-group comparisons were made by using independent t-test and Chi-square analyses. RESULTS: A total of 1068 patients met inclusion criteria and 31.6% were managed in accordance with the AUA best practice statement by not receiving antibiotics beyond 24 hours of surgery. Overall, 33 patients developed a culture-proven UTI within 30 days after surgery, with no difference in UTI rate between patients who did and did not receive home-going antibiotics (2.9% vs 3.6%, respectively; p = 0.5). Rates of unplanned hospital encounters also did not differ between groups (23.7% vs 27.0%, respectively; p = 0.2). On multivariate regression, culture proven UTI within 1 year before surgery was the only factor associated with postoperative UTI (odds ratio: 10.8, p < 0.0001). CONCLUSIONS: Patients who did and did not receive home-going antibiotics after ureteroscopy demonstrated similar rates of postoperative UTI and unplanned hospital encounters. These results suggest that there is no benefit to extended antibiotics after ureteroscopy. The minority of patients managed in accordance with the AUA best practice statement highlights room for quality improvement. PMID- 29179567 TI - Number and Frequency of Routinely Applied Painful Procedures in University Neonatal Intensive Care Unit. AB - Neonates at the neonatal intensive care unit (NICU) are at high risk for procedural pain exposure. This study describes the type and frequency of procedures in neonates admitted to University Intensive Care Unit. This was a prospective cohort study of 150 neonates admitted to the NICU during the first 7 days of life at a governmental hospital. The type and frequency of procedures were evaluated using a tool which included the type and number of procedures performed per shift. A total of 14,008 painful procedures were performed on neonates with an average of 97.11 painful procedures per baby and 13.9/day for each baby. Adhesive removal (21.3%) was the most frequently performed procedure. The number of painful procedures was inversely correlated with gestation age ( p < .001) and birth weight ( p < .001). The number of painful procedures performed on neonates is high, particularly for neonates with small gestational age and low birth weight babies. PMID- 29179566 TI - The safety assessment of herbals with a new and ethical approach. AB - The increasing use of plant medicines (herbals) in Europe needs a shared methodology to determine the toxicity and the daily exposure level to these drugs. For this reason, the European regulatory agencies have undertaken a study that could meet popular uses and toxicological research in different countries of the Union. Here we list some examples of the most used herbal drug classes and we propose a decision-making process based on their characteristics, their content in active principles and on the basis of the present scientific pharmacological and toxicological literature. The proposed decision tree actually makes easier for the assessor to quickly and accurately evaluate the accredited indexes for risk and toxicity assessment based on the preclinical literature data and using the correct classification that some of them may have because they are already present in medicinal products or used as food. PMID- 29179568 TI - Atherogenic Lipoprotein Subfractions and Carotid Atherosclerosis in Menopausal Women. AB - The aim of the study was to evaluate the relationship between cholesterol contained in very-low-density lipoproteins (VLDL-C), intermediate-density lipoproteins (IDL-C), low-density lipoproteins, high-density lipoproteins, and carotid intima-media thickness (cIMT) and carotid plaques in 228 postmenopausal women (63.1 +/- 8.2 years) who participated in the ATENA Project and underwent clinical, biochemical (including the assay of lipoproteins using the Lipoprint system), and carotid ultrasound tests. Very-low-density lipoprotein cholesterol had a statistically significant linear association with cIMT ( P < .001), which remained significant after adjustment for age, smoking, systolic blood pressure, glucose, and body mass index ( r2 = .20, P < .05). Higher concentrations of IDL-C and cholesterol contained in triglyceride-rich lipoproteins (TRL-C, ie, VLDL-C + IDL-C) were associated with plaques in the common carotid (tertile III/tertile I: odds ratio [OR] = 2.52, 95% confidence interval [CI] = 1.21-5.32, P < .02; OR = 2.30, 95% CI = 1.05-5.01, P < .05, respectively), after adjustment for main cardiovascular risk factors. In conclusion, high concentrations of VLDL-C and TRL C are independently associated with the presence of carotid plaques. Their assay represents a useful tool for improving our knowledge on the role of different classes of lipoproteins in atherosclerosis. PMID- 29179569 TI - Self-Injurious Behavior in Children With Developmental Disabilities: A Systematic Review of Behavioral Intervention Literature. AB - We reviewed single-case research studies examining the effects of behavioral interventions for self-injurious behavior (SIB) in young children with autism and developmental disabilities. Systematic searches of electronic databases, journals, and reference lists identified 46 studies (66 participants younger than the age of 12) meeting inclusion criteria. Studies were examined based on (a) participant demographics, (b) topography and function of SIB, (c) type of functional behavior assessment (FBA), (d) intervention procedures and outcomes, and (e) experimental design and measurement. Intervention strategies were categorized as antecedent manipulations, teaching behavior, consequence-based procedures, and/or extinction procedures. Positive outcomes were reported for 78% of participants in the reviewed studies and 88% of the participants were diagnosed with autism. Results suggest the effectiveness of behavioral interventions to decrease SIB for young children with disabilities; however, the frequent use of packaged interventions without component analysis limits the conclusiveness of any treatment recommendation. Suggestions for future research are discussed. PMID- 29179570 TI - A narrow view: The conceptualization of sexual problems in human sexuality textbooks. AB - This study examined the ways in which the meaning of 'sexual problems' is constructed and defined in undergraduate human sexuality textbooks. Drawing on feminist and critical discourse frameworks, the dominant as well as the absent/marginalized discourses were identified using critical discourse analysis. Sexual difficulties were largely framed by the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders. Thus, medical discourse was privileged. Alternative conceptualizations and frameworks, such as the New View of Women's Sexual Problems, were included marginally and peripherally. We argue that current constructions of sexuality knowledge reinforce, rather than challenge, existing hegemonic discourses of sexuality. PMID- 29179571 TI - Role of Basal Cells in Producing Persistent Lentivirus-Mediated Airway Gene Expression. AB - Cystic fibrosis (CF) lung disease is an ideal candidate for a genetic therapy. It has been shown previously that preconditioning with lysophosphatidylcholine (LPC) prior to lentiviral (LV) vector delivery results in long-term in vivo gene expression in the airway epithelium of CF mice. It was hypothesized that this outcome is largely due to transduction of airway basal cells that in turn pass the transgene onto their progeny. The aim of these studies was to confirm if the in vivo delivery of a human immunodeficiency virus type 1 (HIV-1) vesicular stomatitis virus envelope glycoprotein (VSV-G) pseudotyped LV vector following LPC airway conditioning results in transduction of mouse airway basal cells in situ and if the transgene is passed onto their progeny. Additionally, the study sought to determine the efficiency of in vitro transduction of human airway basal cells. First, normal mouse nasal airways were pretreated with LPC prior to delivery of a HIV-1 VSV-G pseudotyped LV vector carrying a LacZ marker gene (LV LacZ). An epithelial ablation model utilizing polidocanol was then used to demonstrate that clonal outgrowth of linear and spotted clusters of transgene expressing ciliated, basal, and goblet cells occurs following transduction of basal cells. Second, human basal cells were cultured from primary bronchial epithelial cells, with identity confirmed by keratin 5 staining. High levels of transgene expression were found following LV-LacZ transduction. This study demonstrates the ability of the vector delivery protocol to transduce mouse airway basal cells, the LV vector to transduce human basal cells, and the likely role of these cells in maintaining long-term gene expression. These findings support and further develop the potential of LV gene transfer for persistent correction of CF airway disease. PMID- 29179573 TI - The Value of Rehabilitation Medicine for Patients Receiving Palliative Care. AB - BACKGROUND: Rehabilitation medicine is a multidisciplinary field aimed at improving patients' quality of life by improving function. Patients receiving palliative care frequently share common symptoms including fatigue, decreased functional independence, mood disorders, pain, and breathlessness. Many rehabilitation interventions can improve these symptoms. OBJECTIVE: To evaluate the scope and effectiveness of rehabilitation interventions and exercise programs in improving quality of life and distressing symptoms in patients receiving palliative care. METHODS: We conducted a literature review of cancer rehabilitation topics and techniques specifically applied to patients with life limiting conditions. Exercise and other rehabilitation interventions were analyzed for their effects on common symptoms and disabilities experienced by this patient population. CONCLUSION: Current available literature supports the use of exercise programs and rehabilitation interventions to improve fatigue, mood, functional independence, breathlessness, and pain. Rehabilitation and palliative care practitioners share many goals in their approach to patient care and augment one another well. Palliative care providers should consider referral to physiatry (physical medicine and rehabilitation) to help optimize patients' quality of life. PMID- 29179572 TI - When and Why Do Neonatal and Pediatric Critical Care Physicians Consult Palliative Care? AB - BACKGROUND: Parents of children admitted to neonatal and pediatric intensive care units (ICUs) are at increased risk of experiencing acute and post-traumatic stress disorder. The integration of palliative care may improve child and family outcomes, yet there remains a lack of information about indicators for specialty level palliative care involvement in this setting. OBJECTIVE: To describe neonatal and pediatric critical care physician perspectives on indicators for when and why to involve palliative care consultants. METHODS: Semistructured interviews were conducted with 22 attending physicians from neonatal, pediatric, and cardiothoracic ICUs in a single quaternary care pediatric hospital. Transcribed interviews were analyzed using content and thematic analyses. RESULTS: We identified 2 themes related to the indicators for involving palliative care consultants: (1) palliative care expertise including support and bridging communication and (2) organizational factors influencing communication including competing priorities and fragmentation of care. CONCLUSIONS: Palliative care was most beneficial for families at risk of experiencing communication problems that resulted from organizational factors, including those with long lengths of stay and medical complexity. The ability of palliative care consultants to bridge communication was limited by some of these same organizational factors. Physicians valued the involvement of palliative care consultants when they improved efficiency and promoted harmony. Given the increasing number of children with complex chronic conditions, it is important to support the capacity of ICU clinical teams to provide primary palliative care. We suggest comprehensive system changes and critical care physician training to include topics related to chronic illness and disability.

PMID- 29179574 TI - Life-Sustaining Treatment Status at the Time of Death in a Japanese Pediatric Intensive Care Unit. AB - BACKGROUND: Substantial variability exists among countries regarding the modes of death in pediatric intensive care units (PICUs). However, there is limited information on end-of-life care in Japanese PICUs. Thus, this study aimed to elucidate the characteristics of end-of-life care practice for children in a Japanese PICU. METHODS: We examined life-sustaining treatment (LST) status at the time of death based on medical chart reviews from 2010 to 2014. All deaths were classified into 3 groups: limitation of LST (limitation group, death after withholding or withdrawal of LST or a do not attempt resuscitation order), no limitation of LST (no-limitation group, death following failed resuscitation attempts), or brain death (brain death group). RESULTS: Of the 62 patients who died, 44 (71%) had limitation of LST, 18 (29%) had no limitation of LST, and none had brain death. In the limitation group, the length of PICU stay was longer than that in the no-limitation group (13.5 vs 2.5 days; P = .01). The median time to death after the decision to limit LST was 2 days (interquartile range: 1-5.5 days), and 94% of the patients were on mechanical ventilation at the time of death in the limitation group. CONCLUSIONS: Although limiting LST was a common practice in end-of-life care in a Japanese PICU, a severe limitation of LST such as withdrawal from the ventilator was hardly practiced, and a considerable LST was still provided at the time of death. PMID- 29179576 TI - Rates and Predictors of Conversion to Schizophrenia or Bipolar Disorder Following Substance-Induced Psychosis. AB - OBJECTIVE: The authors investigated the rates of conversion to schizophrenia and bipolar disorder after a substance-induced psychosis, as well as risk factors for conversion. METHOD: All patient information was extracted from the Danish Civil Registration System and the Psychiatric Central Research Register. The study population included all persons who received a diagnosis of substance-induced psychosis between 1994 and 2014 (N=6,788); patients were followed until first occurrence of schizophrenia or bipolar disorder or until death, emigration, or August 2014. The Kaplan-Meier method was used to obtain cumulative probabilities for the conversion from a substance-induced psychosis to schizophrenia or bipolar disorder. Cox proportional hazards regression models were used to calculate hazard ratios for all covariates. RESULTS: Overall, 32.2% (95% CI=29.7-34.9) of patients with a substance-induced psychosis converted to either bipolar or schizophrenia-spectrum disorders. The highest conversion rate was found for cannabis-induced psychosis, with 47.4% (95% CI=42.7-52.3) converting to either schizophrenia or bipolar disorder. Young age was associated with a higher risk of converting to schizophrenia. Self-harm after a substance-induced psychosis was significantly linked to a higher risk of converting to both schizophrenia and bipolar disorder. Half the cases of conversion to schizophrenia occurred within 3.1 years after a substance-induced psychosis, and half the cases of conversion to bipolar disorder occurred within 4.4 years. CONCLUSIONS: Substance-induced psychosis is strongly associated with the development of severe mental illness, and a long follow-up period is needed to identify the majority of cases. PMID- 29179577 TI - Service Use Preceding Opioid-Related Fatality. AB - OBJECTIVE: This study analyzed health service patterns before opioid-related death among nonelderly individuals in the Medicaid program, focusing on decedents with and without past-year diagnoses of noncancer chronic pain. METHODS: The authors identified opioid-related decedents, age <=64 years, in the Medicaid program and characterized their clinical diagnoses, filled medication prescriptions, and nonfatal poisoning events during the 30 days and 12 months before death. The study group included 13,089 opioid-related deaths partitioned by presence or absence of chronic noncancer pain diagnoses in the last year of life. RESULTS: Most decedents (61.5%) had received clinical diagnoses of chronic noncancer pain conditions in the last year of life. As compared with decedents without chronic pain diagnoses, those with these diagnoses were significantly more likely to have filled prescriptions for opioids (49.0% versus 17.2%) and benzodiazepines (52.1% versus 26.6%) during the last 30 days of life, while diagnoses of opioid use disorder during this period were uncommon in both groups (4.2% versus 4.3%). The chronic pain group was also significantly more likely than the nonpain group to receive clinical diagnoses of drug use (40.8% versus 22.1%), depression (29.6% versus 13.0%) or anxiety (25.8% versus 8.4%) disorders during the last year of life. CONCLUSIONS: Persons dying of opioid-related causes, particularly those who were diagnosed with chronic pain conditions, commonly received services related to drug use disorders and mental disorders in the last year of life, though opioid use disorder diagnoses near the time of death were rare. PMID- 29179578 TI - Impact of SSRI Therapy on Risk of Conversion From Mild Cognitive Impairment to Alzheimer's Dementia in Individuals With Previous Depression. AB - OBJECTIVE: Depression is associated with an increased risk of Alzheimer's disease. Research has shown that the selective serotonin reuptake inhibitor (SSRI) citalopram decreases amyloid-beta generation and plaque load. The authors evaluated the impact of SSRI treatment on CSF biomarkers and progression from mild cognitive impairment (MCI) to Alzheimer's dementia. METHOD: Data sets from 755 currently nondepressed participants from the longitudinal Alzheimer's Disease Neuroimaging Initiative were evaluated by Kaplan-Meier analysis and analyses of variance and covariance with ApoE4 status and age as covariates. RESULTS: In MCI patients with a history of depression, long-term SSRI treatment (>4 years) was significantly associated with a delayed progression to Alzheimer's dementia by approximately 3 years, compared with short-term SSRI treatment, treatment with other antidepressants, or no treatment and compared with MCI patients without a history of depression. No differences in CSF biomarker levels were observed between treatment groups. CONCLUSIONS: Long-term SSRI treatment may delay progression from MCI to Alzheimer's dementia. PMID- 29179579 TI - A Population-Based Longitudinal Study of Symptoms and Signs Before the Onset of Psychosis. AB - OBJECTIVE: The authors sought to characterize the symptoms of patients later hospitalized for psychotic disorders in primary mental health outpatient settings, and to investigate whether these symptoms can be used to predict later onset of psychotic illness. METHOD: This was a population-based historical prospective cohort study using national registers of clinical psychiatric services. The sample (N=114,983) comprised 18- to 21-year-olds serving in the Israeli military and examined in military mental health outpatient clinics across 72 consecutive months. RESULTS: Overall, 1,092 individuals (0.95%) not diagnosed with a psychotic disorder at the time of examination were hospitalized for nonaffective psychotic disorder up to 9 years after the index examination. A principal components analysis of symptoms presented at index examination found that a symptom cluster of thought disorder, perceptual abnormalities, poor orientation, and suicidality was associated with an increased risk for hospitalization for nonaffective psychotic disorder within 14 days after examination (hazard ratio=45.80, 95% CI=22.87-91.73), 15-111 days after examination, (hazard ratio=19.59, 95% CI=13.08-29.33), 112-365 days after examination (hazard ratio=4.94, 95% CI=2.59-9.40), and 1-3.5 years after examination (hazard ratio=3.42, 95% CI=2.21-5.28), but not for hospitalization 3.5 years or more after examination (hazard ratio=1.57, 95% CI=0.91-2.71). Despite the increased risk, the positive predictive values of this symptom cluster were low, ranging from 0.54% to 1.99%. CONCLUSIONS: In 18- to 21-year olds, the presence of psychotic symptoms was associated with later hospitalization for a nonaffective psychotic disorder. However, the low positive predictive values of symptoms elicited in primary mental health care settings suggest that symptoms alone are not useful in predicting later hospitalization for nonaffective psychotic disorder. PMID- 29179580 TI - Association of FV G1691A Polymorphism but not A4070G With Coronary Artery Disease. AB - Coronary artery disease (CAD) is one of the chief causes of death in the world. Several hypotheses have been promoted as for the origin of the disease, among which are genetic predispositions and/or environmental factors. The aim of this study was to determine the effect of factor V (FV) gene polymorphisms (Leiden, G1691A [FVL] and HR2 A4070G) and to analyze their association with traditional risk factors in assessing the risk of CAD. Our study population included 200 Tunisian patients with symptomatic CAD and a control group of 300 participants matched for age and sex. All participants were genotyped for the FVL and HR2 polymorphisms. Multivariate logistic regression was applied to analyze independent factors associated with the risk of CAD. Our analysis showed that the FVL A allele frequency ( P < 10-3, odds ratio [OR] = 2.81, 95% confidence interval [CI] = 1.6-4.9) and GA genotype ( P < 10-3, OR = 4.03, 95% CI = 2.1-7.6) are significantly more prevalent among patients with CAD compared to those controls and may be predisposing to CAD. We further found that the FVL mutation is an independent risk factor whose effect is not modified by other factors (smoking, diabetes, hypertension, dyslipidemia, and a family history of CAD) in increasing the risk of the disease. However, analysis of FV HR2 variation does not show any statistically significant association with CAD. The FVL polymorphism may be an independent risk factor for CAD. However, further investigations on these polymorphisms and their possible synergisms with traditional risk factors for CAD could help to ascertain better predictability for CAD susceptibility. PMID- 29179581 TI - Hadza Men With Lower Voice Pitch Have a Better Hunting Reputation. AB - Previous research with hunter-gatherers has found that women perceive men with voices manipulated to be lower in pitch to be better hunters, and men perceive women with lower pitch to be better gatherers. Here, we test if actual voice pitch is associated with hunting and gathering reputations in men and women, respectively. We find that voice pitch does relate to foraging reputation in men, but not in women, with better hunters having a lower voice pitch. In addition, we find that the previously documented relationship between voice pitch and reproductive success no longer holds when controlling for hunting reputation, but hunting reputation remains a significant predictor of reproductive success when controlling for voice pitch. This raises the possibility that voice pitch is being selected for in hunter-gatherers because of the relationship between voice pitch and hunting reputation. PMID- 29179582 TI - Is Support of Censoring Controversial Media Content for the Good of Others? Sexual Strategies and Support of Censoring Pro-Alcohol Advertising. AB - At least in the United States, there are widespread concerns with advertising that encourages alcohol consumption, and previous research explains those concerns as aiming to protect others from the harm of excessive alcohol use.1 Drawing on sexual strategies theory, we hypothesized that support of censoring pro-alcohol advertising is ultimately self-benefiting regardless of its altruistic effect at a proximate level. Excessive drinking positively correlates with having casual sex, and casual sex threatens monogamy, one of the major means with which people adopting a long-term sexual strategy increase their inclusive fitness. Then, one way for long-term strategists to protect monogamy, and thus their reproductive interest is to support censoring pro-alcohol advertising, thereby preventing others from becoming excessive drinkers (and consequently having casual sex) under media influence. Supporting this hypothesis, three studies consistently showed that restricted sociosexuality positively correlated with support of censoring pro-alcohol advertising before and after various value , ideological-, and moral-foundation variables were controlled for. Also as predicted, Study 3 revealed a significant indirect effect of sociosexuality on censorship support through perceived media influence on others but not through perceived media influence on self. These findings further supported a self interest analysis of issue opinions, extended third-person-effect research on support of censoring pro-alcohol advertising, and suggested a novel approach to analyzing media censorship support. PMID- 29179583 TI - Oncolytic Viruses for Tumor Precision Imaging and Radiotherapy. AB - In 2003 in China, Peng et al. invented the recombinant adenovirus expressing p53 (Gendicine) for clinical tumor virotherapy. This was the first clinically approved gene therapy and tumor virotherapy drug in the world. An oncolytic herpes simplex virus expressing granulocyte-macrophage colony-stimulating factor (Talimogene laherparepvec) was approved for melanoma treatment in the United States in 2015. Since then, oncolytic viruses have been attracting more and more attention in the field of oncology, and may become novel significant modalities of tumor precision imaging and radiotherapy after further improvement. Oncolytic viruses carrying reporter genes can replicate and express genes of interest selectively in tumor cells, thus improving in vivo noninvasive precision molecular imaging and radiotherapy. Here, the latest developments and molecular mechanisms of tumor imaging and radiotherapy using oncolytic viruses are reviewed, and perspectives are given for further research. Various types of tumors are discussed, and special attention is paid to gastrointestinal tumors. PMID- 29179584 TI - Maternal height and risk of hypertensive disorders in pregnancy. AB - PURPOSE: The relationship between maternal height and gestational hypertensive disorders was examined in a cohort of Chinese gravidae managed in 1997-2013 to clarify the association between short stature with preeclampsia (PE) and gestational hypertension (GH). MATERIALS AND METHODS: Retrospective study of 87 290 gravidae categorized by their height into four quartile groups. The impact of short stature, defined as height in the lowest quartile, on incidence of PE and GH was studied in relation to the presence of risk factors. The independent role of short stature was determined by regression analysis. RESULTS: The 25th, 50th, and 75th percentile values of height were 154 cm, 158 cm, and 161 cm respectively. The incidence of PE, but not GH, was inversely correlated with height (p = .025). Short stature altered the impact of parity status, advanced age, high body mass index, infant gender, and medical history, on incidence of PE but not GH. On regression analysis, short stature increased risk of PE (adjusted RR 1.134, 95%CI 1.005-1.279) but reduced GH (adjusted RR 0.836, 95%CI 0.718 0.974). CONCLUSIONS: Maternal short stature should be defined according to distribution in a specific ethnic group, and it exerts a significant but opposite effect on the incidence of PE versus GH.

PMID- 29179588 TI - Listeriosis in two twin pregnancies after in vitro fertilization with differential outcome and literature review. AB - PURPOSE: In vitro fertilization (IVF) has become a very common procedure in the infertility practice due to its accessibility. The study is aiming at presenting two twin pregnancy-related infections caused by Listeria monocytogenes and reviewing the reported cases of listeriosis in multiple pregnancies. MATERIALS AND METHODS: Two listeriosis cases with twin pregnancy after IVF were described and the literature on pregnancy-associated listeriosis was reviewed. RESULTS: The risk of listeriosis should be underscored in pregnant women after IVF, and timely diagnosis and rational treatment might result in a better outcome. CONCLUSIONS: The current study highlights that the infections due to L. monocytogenes should be noted in multiple pregnancies after IVF. PMID- 29179587 TI - In vitro differentiation of progenitor cells isolated from juvenile pig hearts - expression of relevant gene and protein markers. AB - OBJECTIVES: Heart failure is a significant cause of mortality worldwide, and most current therapies treat only its symptoms. The results of cardiac stem cell research suggest a promising treatment option for heart failure, but there is currently an unmet demand for better research models. We have therefore, for the first time, isolated, expanded and differentiated progenitor cells obtained from juvenile pig hearts to use as a platform for cardiac stem cell research. DESIGN: Progenitor cells were isolated from the left ventricles of porcine hearts using collagenase enzymatic digestion and Percoll(r)-gradient centrifugation. Cells were proliferated in Matrigel(r)-coated wells. Cell differentiation was initiated by applying 5-azacytidine and subsequently controlled by modifying the serum concentration. Western blotting and qPCR were used to determine protein and gene expression, respectively. RESULTS: Cardiac-specific genes, from the following proteins: troponin I-3, and myosin-heavy-chain 7 were stably expressed during proliferation and differentiation. Connexin-43 was upregulated and Actinin alfa 2 was downregulated during differentiation. The immature-cardiomyocyte marker GATA binding protein 4 was stably expressed but with a decrease in expression at day 4 of differentiation. Smooth muscle actin decreased in expression and Von Willebrand factor were stably expressed during differentiation. Smooth muscle protein expression was documented but no expression of cardiac-specific proteins after differentiation was found. CONCLUSION: The isolated progenitor cells had key cardiac-lineage gene expression characteristics but they did not express cardiac-specific proteins. Smooth muscle protein was expressed confirming commitment to the smooth muscle lineage. PMID- 29179585 TI - Immune-based strategies for mood disorders: facts and challenges. AB - INTRODUCTION: Inflammation seems to play a role in the pathophysiology of mood disorders, including major depressive disorder (MDD) and bipolar disorder (BD). In the last years several studies have shown increased levels of inflammatory and/or immune markers in patients with mood disorders. Accordingly, the immune system has become a target of interest for the development of biomarkers and therapeutics for mood disorders. Areas covered: Here, we review the evidence showing low-grade inflammation in mood disorders and the studies evaluating immune-based strategies for the treatment of these conditions. Expert commentary: Clinical trials with non-steroidal anti-inflammatory drugs, polyunsaturated acids, N-acetylcysteine, anti-cytokines, physical activity and probiotics have provided promising results in terms of antidepressant efficacy in patients with MDD and BD. Regarding stem cells, only studies with animal models have been performed so far with interesting pre-clinical results. Due to the preliminary nature of the results, most of the clinical studies need to be replicated and/or confirmed in larger clinical settings, embracing the highly heterogeneous pathophysiology of mood disorders.

AB - OBJECTIVE: This study was designed to evaluate the efficacy of aspirin or heparin or both in the treatment for recurrent spontaneous abortion (RSA) in women with antiphospholipid antibody syndrome (APS). METHODS: Systematic searches for randomized clinical trials (RCTs) evaluating on live birth and preterm delivery, preeclampsia, intrauterine growth restriction, gestational diabetes, bleeding of RSA with APS patients receiving aspirin, and heparin therapy were carried out, from PubMed, EMBASE, ScienceDirect, and CNKI. Related data were extracted from eligible studies and then subjected to Reviewer Manage 5.3 for analysis. Relative risk (RR) and its 95% confidence interval were calculated. RESULTS: Nineteen publications with randomized controlled trials were selected for this study, which included a total of 1251 pregnant patients with diagnosis of RSA with APS. With respect to live birth, it was remarkably improved in aspirin plus heparin or heparin alone group [RR =1.23, 95% CI (1.12-1.36), p < .0001; RR = 1.18, 95% CI (1.03-1.35), p = .02]; aspirin alone group, however, there was no statistically significant difference compare to placebo [RR = 0.97, 95% CI (0.80-1.16), p = .71]. Meanwhile, aspirin plus heparin therapy did not significantly reduce the risk of recurrent placenta-mediated pregnancy complications including preterm birth, intrauterine growth retardation (IUGR), gestational diabetes, and minor bleeding. A beneficial therapeutic effect of heparin alone therapy was found on preventing preterm birth and low-dose aspirin plus heparin therapy was significant reduce the risk of preeclampsia. CONCLUSION: An improvement of pregnancy outcomes in women with RSA and APS can be achieved by treatment strategies combining low-dose aspirin plus heparin or heparin alone. Aspirin alone, by contrast, seemed inferior to other treatments in achieving more live birth.

AB - This study compared the antiproliferative effects of metformin and progesterone, via examination of the Bcl-2/Bax-caspase apoptotic pathway in estrogen-induced endometrial hyperplasia (EH) in 40 rats. Two rats died after bilateral oophorectomy, and 1 week after surgery, the remaining 38 were randomly divided into three groups: the first (control, n = 12) received 4 mg/kg 17beta estradiol hemihydrate (E); the second (n = 13) received 4 mg/kg 17beta estradiol hemihydrate and 50 mg/kg metformin (E + M); and the third (n = 13) received 4 mg/kg 17beta estradiol hemihydrate and 1 mg/day medroxiprogesterone acetate (E + MPA). Histological markers and Bcl-2, Bax and caspase 9 expression were analyzed. Luminal epithelial thickness, density of gland and epithelial height was significantly higher in group E than in groups E + M and E + MPA. Histopathologic parameters were similar between the E + M and E + MPA groups. Bcl-2/Bax ratio was significantly decreased in the E + M and E + MPA groups and caspase 9 expression levels were significantly increased in the E + M and E + MPA groups, compared with the control group. In addition, Bcl-2/Bax ratio and caspase 9 expression were similar between the E + M and E + MPA groups. The data indicate that metformin reduces estrogen-induced EH in rats, via activation of the caspase dependent mitochondrial apoptotic pathway, to the same degree as progesterone. PMID- 29179591 TI - Effects of Gly71Arg mutation in UGT1A1 gene on neonatal hyperbilirubinemia: a systematic review and meta-analysis. AB - OBJECTIVE: The associations between Gly71Arg polymorphism in the coding region of uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) gene and the risk of neonatal hyperbilirubinemia remained controversial. Therefore, a meta-analysis of observational studies has been conducted to assess the relationship between UGT1A1 gene polymorphism of Gly71Arg and neonatal hyperbilirubinemia susceptibility. METHODS: An electronic literature search from online databases, such as PubMed, Embase, Cochrane, and Scopus was conducted to identify eligible studies. The effect summary odds ratio (OR) with 95% confidence interval (CI) was used to estimate the strength of association in the fixed or random effects model, based on the absence or presence of heterogeneity. RESULTS: A total of 32 eligible studies involving 2634 cases of neonatal hyperbilirubinemia and 4996 controls were enrolled in this meta-analysis. The combined results showed that UGT1A1 Gly71Arg polymorphism was associated with an increased risk of neonatal hyperbilirubinemia in all genetic models (homozygote model: OR = 6.12, 95% CI = 4.42-8.46; heterozygote model: OR = 2.06, 95% CI = 1.82-2.33; dominant model: OR = 2.44, 95% CI = 2.03-2.93; recessive model: OR = 4.79, 95% CI = 3.48-6.59, and allelic model: OR = 2.37, 95% CI = 1.98-2.82). Subgroup analysis by ethnicity strongly validated this correlation in Asians but slightly in Caucasian population. CONCLUSIONS: This meta-analysis confirms that UGT1A1 Gly71Arg polymorphism significantly increases the risk of neonatal hyperbilirubinemia in Asian population, but results from the Caucasians were conflicting and further well-designed epidemiological studies are, therefore, required to more adequately assess this correlation. PMID- 29179592 TI - Elevated plasma procalcitonin level predicts poor prognosis of ST elevation myocardial infarction in Asian elderly. AB - Previous studies have focused on relationship between plasma procalcitonin level and myocardial infarction risk, but this relationship in Asian elderly has not been investigated. The aim of this study was to reveal the association of peripheral procalcitonin concentration (both immediate and average levels) with myocardial infarction prognosis in Asian elderly. A total of 400 ST-elevation myocardial infarction patients, 400 unstable angina patients and 400 controls were included. Plasma levels of high-sensitivity C-reactive protein and procalcitonin were measured using commercially available kits. Each myocardial infarction patient received a standard therapy and a 12-month follow-up unless major adverse cardiac events occurred. On admission, plasma procalcitonin level was higher in myocardial infarction patients than in unstable angina patients and controls (p < .001). In the follow-up period, 142 myocardial infarction patients suffered from major adverse cardiac events, and other 258 myocardial infarction patients did not. Higher admission, peak and average plasma levels of procalcitonin in the first week after chest pain onset were associated with elevated risk of major adverse cardiac events (HR: 1.46, 95%CI: 1.18-1.99; HR: 2.57, 95%CI: 1.99-3.52; HR: 2.36, 95%CI: 1.81-3.00). Plasma procalcitonin level had a positive linear correlation with plasma level of high-sensitivity C reactive protein on admission (r = 0.650, p < .001). In conclusion, peripheral concentration of procalcitonin (both immediate and average levels) might be an independent predictor for prognosis in myocardial infarction patients. Prognostic significance of procalcitonin might be implicated in inflammation. PMID- 29179593 TI - De-novo identification of specific exposure biomarkers of the alternative plasticizer di(2-ethylhexyl) terephthalate (DEHTP) after low oral dosage to male volunteers by HPLC-Q-Orbitrap-MS. AB - CONTEXT: Human exposure biomonitoring relies on the availability of specific, sensitive biomarkers. For emerging chemicals, the identification (prediction, synthesis, verification) of such biomarkers is time and cost intensive. OBJECTIVE: This study aimed to further elucidate the urinary metabolic profile of the plasticizer di(2-ethylhexyl) terephthalate (DEHTP) in search of probably additional biomarkers of exposure. MATERIALS AND METHODS: Urine samples of an oral low-dose volunteer study were analysed by HPLC-Q-Orbitrap-MS combined with a commercial data mining software. Metabolite identification was based on isotopic pattern, accurate masses of product ions and excretion profiles. RESULTS: Nine phase I metabolites of DEHTP were tentatively identified by HPLC-Q-Orbitrap-MS. Four previously described, side chain oxidized monoester metabolites were confirmed in all samples. In addition, five previously unknown downstream metabolites were tentatively identified. DISCUSSION AND CONCLUSION: The excretion profiles obtained by HPLC-Q-Orbitrap-MS were in good agreement with quantitative HPLC-QqQ-MS data. For the newly discovered metabolites, plausible excretion profiles, similar to the ones of the known metabolites, were obtained. The presented approach proved to be successful for metabolite screening in urine samples after low-dose exposure and will be applied in future human metabolism studies for a fast, reliable and cost effective identification of specific biomarkers of exposure. PMID- 29179594 TI - Ultrabilitation: beyond recovery-oriented rehabilitation. AB - PURPOSE: Current rehabilitation models emphasize therapy that attempts to return to "normal" the lives of persons who are disabled. An opportunity is available to scrutinize whether this recovery orientation of rehabilitation is necessarily optimal. METHOD: This conceptual article uses reasoning, informed by experience and a nonsystematic review of literature across diverse disciplines. RESULTS: For some persons with disability, optimizing recovery might be unwanted or insufficient. To expand rehabilitation, we append the Latin "ultra", beyond, to "habilitare", make fit. The resulting term, "ultrabilitate", commits to human flourishing that moves persons toward, around or beyond recovery of particular functioning. CONCLUSIONS: By expanding the scope of disability management, ultrabilitation could inform therapy selection and facilitate human flourishing. Empirical research is needed to test our ideas. Implications for rehabilitation Despite significant progress, rehabilitation limits some people with disabilities. Modern health systems still benchmark therapy for rehabilitation against "normal" or species-typical standards to aid recovery. "Ultrabilitation", meaning "beyond fitness", promotes flourishing, either without an interest in recovery or in moving toward, beyond or around recovery. Biological, social and technological conditions are needed to support ultrabilitation. Ultrabilitation complements rehabilitation when rehabilitation is not sufficient to optimize functioning and personal growth. PMID- 29179595 TI - Efficacy and safety of aripiprazole lauroxil once-monthly versus aripiprazole once-monthly long-acting injectable formulations in patients with acute symptoms of schizophrenia: an indirect comparison of two double-blind placebo-controlled studies. AB - BACKGROUND: Aripiprazole lauroxil (AL) is a long-acting injectable atypical antipsychotic recently approved for the treatment of schizophrenia. OBJECTIVE: To indirectly compare the safety and efficacy of AL and aripiprazole once-monthly (AOM). METHODS: A systematic search was performed to identify randomized, controlled trials of AOM and AL that met criteria for indirect comparison according to Bayesian network meta-analysis. The analysis indirectly compared AL and AOM treatment groups for efficacy by mean change in Positive and Negative Syndrome Scale (PANSS) total score and >=30% reduction in PANSS total score, as well as tolerability including adverse events, akathisia, and weight gain. RESULTS: Two studies were selected, resulting in three active-treatment groups: AL 441 mg, AL 882 mg, and AOM 400 mg. All active treatments were efficacious compared with placebo. There were no differences in indirect comparisons of akathisia. All three groups showed some weight gain, but only the AOM 400 mg group was significantly greater than placebo. CONCLUSIONS: Results of this indirect comparison found that both doses of AL and the single AOM dose were therapeutic and efficacious for the treatment of schizophrenia with a similar safety profile. PMID- 29179596 TI - Celastrol attenuates impairments associated with lipopolysaccharide-induced acute respiratory distress syndrome (ARDS) in rats. AB - Celastrol, a constituent from a traditional Chinese medicinal herb belonging to the family Celastraceae, has been shown to impart anti-inflammatory properties, in part, by inhibiting NF-kappaB activity and related induction of pro inflammatory cytokine formation/release. The present study investigated the effects of celastrol in an animal model of acute respiratory distress syndrome (ARDS) induced by intratracheal administration of lipopolysaccharides (LPSs). Celastrol pre-treatment groups received celastrol by intraperitoneal injection on seven consecutive days before LPS treatment. In rats evaluated 24 h after LPS administration, oxygenation indices and lung injury were measured, as were levels of inflammatory cells and cytokines in isolated bronchoalveolar lavage fluid (BALF). Lung tissue expression of proteins involved in NF-kappaB and ERK/MAPK pathways were measured by Western blot analyses. Celastrol pre-treatments appeared to attenuate LPS-induced lung injury and inflammatory responses in the rats, including decreases in inducible aggregation?infiltration of inflammatory cells and production/release of pro-inflammatory cytokines into the lung airways. Celastrol appeared to also inhibit NF-kappaB activation, but had no effect on ERK/MAPK pathways in the LPS-induced ARDS. The results here thus indicated that celastrol pre-treatment could impart protective effects against LPS-induced ARDS, and that these effects may be occurring through an inhibition of induction of NF kappaB signaling pathways. PMID- 29179597 TI - Spontaneous extradural hematoma: a rare entity. AB - Spontaneous onset extradural hematoma (EDH) is a very rare entity and has been seen mostly to be associated with adjacent infective pathologies, dural vascular malformations, extradural metastasis, or coagulopathies. We report a series of two such cases and review the literature. One case presented with spontaneous EDH that was managed conservatively and was diagnosed to have chronic kidney disease later; the other had deranged coagulation profile and liver function secondary to drug induced hepatitis and was operated. Both patients were discharged in a stable condition and were improving on follow up. PMID- 29179598 TI - Serum paracetamol-protein adducts in ambulatory subjects: Relationship to recent reported paracetamol use. AB - CONTEXT: Serum paracetamol-protein adducts (PPAs) are a novel potential biomarker of paracetamol exposure. The relationship between serum PPA concentrations and reported paracetamol use in ambulatory adults has not been previously described. MATERIALS AND METHODS: This was a cross-sectional study of ambulatory adults. A detailed medication history was obtained from all subjects and subjects were stratified by reported paracetamol use in the 2 weeks prior to enrolment. Serum PPAs were measured in all subjects and correlated with reported dose, time of last ingestion and demographics. RESULTS: We enrolled 230 in the paracetamol exposure arm and 74 in the no exposure arm. 98/230 (42.6%)of subjects who reported paracetamol exposure had PPA detected and 68/74 (91.9%) of subjects who denied paracetamol exposure had no PPA detected. PPA concentrations were positively correlated with total paracetamol dose and with more recent ingestion. DISCUSSION: Detection of serum PPA generally reflects paracetamol exposure histories in ambulatory adults. Concentrations are well correlated with reported dose and time from last dose. CONCLUSIONS: Serum PPA can be detected with reported therapeutic use of paracetamol but may not be detected in all patients who report taking paracetamol. PMID- 29179599 TI - Fetal facial expressions in small-for-gestational-age and growth-restricted fetuses. AB - OBJECTIVE: To evaluate the frequencies of fetal facial expressions among appropriate-for-gestational-age (AGA), small-for-gestational-age (SGA), and growth-restricted (FGR) fetuses. METHODS: Four-dimensional (4D) ultrasound was used to examine the facial expressions of 50 AGA, 25 SGA, and six FGR fetuses between 28 and 35 weeks of gestation. The frequencies of seven facial expressions during 15-minute recordings were assessed. Comparison of facial expressions among the three groups was performed. RESULTS: Mouthing was the commonest facial expression at 28-35 weeks, and the frequency of mouthing was significantly higher than those of the other six facial expressions in AGA fetuses. Mouthing was the most frequent facial expression, but there was no significant difference in the frequency among mouthing, smiling and blinking in SGA fetuses. Moreover, mouthing displayed a significantly higher frequency than the other facial expressions, except for yawning, smiling, and blinking in FGR fetuses. However, there was no significant difference in the frequency of each facial expression among the three groups. CONCLUSIONS: Our results suggest that the frequencies of fetal facial expressions are not decreased in either SGA or FGR pregnancies. The absence of a decrease in the frequency of each fetal expression in FGR fetuses may be due to increased brain blood flow because of the brain-sparing effect. Moreover, accelerated maturation and development of the brain function, especially the central dopamine system, might be suspected in SGA and FGR fetuses. PMID- 29179600 TI - Nanovaccine for immunotherapy and reduced hepatitis-B virus in humanized model. AB - Chronic Hepatitis B Virus (HBV) infections are severe with weak antiviral immune responses. The lack of an appropriate small animal model for chronic hepatitis, a major hurdle for studying the immunotolerance and immunopathogenesis induced by hepatitis B viral (HBV) infection. In this study, for enhancing the antibody production efficiency the prepared polymeric HBsAg-loaded nanoparticles (nanovaccine) will be tested in immune-deficit mice, which suffer from chronic Hepatitis B virus. Vaccination of Balb/c mice by this prepared nanoparticles that were engrafted with peripheral blood mononuclear cells (PBMCs), which was already lethally irradiated and transplanted by the bone marrow of NOD (knockout mice) mice. In the present study, after the vaccination detected the high frequencies of immunoglobulin G (IgG)-secreting B cells and mitogen-responsive interferon-Y (IFN-Y) secreting T cells in serum, determined by specific ELISA technique. During the entire observation period, unvaccinated animals showed lower concentration of specific IgG secreting B cells and IFN-Y secreting T cells found in comparison to vaccinated mice group. Chronic HBV carrier PBMCs transplanted into the chimera failed to produce antigen and increased the antibodies production due to vaccination. Furthermore, another advantage was that the viral gene expression and viral DNA replication was no longer observed in vaccinated group. This prepared nanovaccine formulations is better for the cure of Hepatitis B viral infection carrier. Therefore, specific memory responses were elicited by vaccination with Hepatitis B virus surface (HBsAg) antigen of chimeric mice transplanted with PBMCs derived from HBV donors. PMID- 29179601 TI - An educational intervention to men for reducing environmental tobacco smoke exposure in their pregnant wives. AB - OBJECTIVE: To determine the effect of education based on health belief model (HBM) on the level of their pregnant wives' environmental tobacco smoke exposure (ETSE). METHODS: This interventional randomized study was conducted on 60 cigarette smoking men who have exposed their pregnant wives to smoke during of their pregnancy. The HBM constructs and weekly ETSE were evaluated by using questionnaire. The intervention group received education with emphasis on the risks of cigarette's smoke on the pregnancy. Then right after the training and 6 weeks after that, HBM constructs and 6 weeks after the training the weekly ETSE were evaluated again. RESULTS: Results showed a significant difference between the mean of perceived susceptibility, perceived benefits and barriers at intake and 6 weeks after the intervention in the intervention group. Also, the level of perceived susceptibility/severity and perceived barriers in both groups were significantly different 6 weeks after the intervention compared to intake time. The ETSE was significantly lower in the intervention group 6 weeks after the intervention in comparison to before the intervention and also to the control group. CONCLUSIONS: This study showed that education husbands would relatively improve their health beliefs and reduce the ETSE of their pregnant wives. PMID- 29179602 TI - Gene Transfer of ZMapp Antibodies Mediated by Recombinant Adeno-Associated Virus Protects Against Ebola Infections. AB - Vectored delivery of the ZMapp antibody cocktail (c2G4, c4G7, and c13C6) by using recombinant adeno-associated viruses (rAAVs) could be useful for preventive immunization against Ebola virus infections because rAAVs can generate long-term antibody expression. Three rAAVs (serotype 9) encoding chimeric ZMapp antibodies were produced by triple-plasmid transfection up to 10 L-scale in WAVE bioreactors using HEK293 cells grown in suspension/serum-free conditions. Efficacy of AAV c2G4 via intravenous (i.v.), intramuscular (i.m.), and intranasal (i.n.) routes of administration was evaluated in mice with two different doses of 2.7 * 1010 and 13.0 * 1010 vector genomes (vg). The best protective efficacies after Ebola challenge were obtained with the i.v. and i.m. routes. Serum concentrations of ZMapp antibodies positively correlated with survivability. Efficacy of the rAAV ZMapp cocktail was then evaluated at a higher dose of 30.0 * 1010 vg. It conferred a more robust protection (90% i.v. and 60% i.m.) than rAAV-c4G7 (30%) and rAAV-c13C6 (70%), both administered separately at the same dose. Delivery of rAAV-c2G4 alone achieved up to 100% protection (100% i.v. and 90% i.m.) at the same dose. In conclusion, the preventive treatment was effective in mice. However, no advantage was observed for using the rAAV-ZMapp cocktail in comparison to the utilization of the single rAAV-c2G4. PMID- 29179603 TI - Nanocapsules for the co-delivery of selol and doxorubicin to breast adenocarcinoma 4T1 cells in vitro. AB - Nanocapsules (NCS-DOX) with an oily core of selol and a shell of poly(methyl vinyl ether-co-maleic anhydride) covalently conjugated to doxorubicin were developed. These nanocapsules are spherical, with an average hydrodynamic diameter of about 170 nm, and with negative zeta potential. NCS-DOX effectively co-delivered the selol and the doxorubicin into 4T1 cells and changed the intracellular distribution of DOX from the nuclei to the mitochondria. Moreover, a significantly increased cytotoxicity against 4T1 cells was observed, which is suggestive of additive or synergic effect of selol and doxorubicin. In conclusion, PVM/MA nanocapsules are suitable platforms to co-deliver drugs into cancer cells. PMID- 29179604 TI - Anterior screw fixation in type II odontoid fracture in an 18-month-old girl: a case report and review of the literature. AB - Odontoid fractures are among the rare cervical spine injuries in pediatric population and thus the optimal management of these injuries is controversial. The increasing trend in road traffic accidents and improvement in diagnostic modalities has led to an increased detection of odontoid fractures in pediatric population. We herein report type II odontoid fracture in an 18-month-old girl after falling off the motorcycle leading to hyperextension and flexion injury. She was successfully treated with anterior odontoid screw fixation followed by immobilization with hard collar for 2 months. Callus formation was detected after 6 weeks and complete remodeling was observed at 6-year follow-up visit. This girl is among the youngest patients with type II odontoid fracture reported in literature being treated with anterior screw fixation. Further clinical series are needed to provide evidence for optimal management of odontoid fractures. PMID- 29179605 TI - Anticoagulant use in atrial fibrillation and risk of dementia: review of contemporary knowledge. AB - INTRODUCTION: Atrial fibrillation (AF) is strongly associated with dementia, including idiopathic dementias such as Alzheimer's disease. The relative risk of dementia is highest in AF patients 70 years and younger, and the burden of exposure to arrhythmia appears to underlie part of the risk. Areas covered: Anticoagulation choices and approach influence dementia risk. In warfarin patients, inadequate time spent in therapeutic range is highly associated with the increased dementia risk long-term. This risk is further accentuated with frequent over anticoagulation in patients also receiving aspirin. Direct oral anticoagulant therapies in early observational studies show that there is potential for improving long-term risk of dementia when compared to warfarin, although prospective trials are needed. AF and dementia are end manifestations of systemic disease; a systemic approach is needed with early treatment of shared risk factors to prevent disease presentation altogether. Expert commentary: In this review, we will bring together available data with regards to the link between anticoagulant use for AF and dementia. Anticoagulation initiation timing, use, and efficacy remain critical risk factors for dementia in AF patients and consequently provide opportunities to decrease risk. PMID- 29179606 TI - Membrane-initiated effects of Serelys(r) on proliferation and apoptosis of human breast cancer cells. AB - Herbal extracts used for the alleviation of postmenopausal symptoms might have a lower risk of breast cancer development than hormone therapy. Serelys(r) is a product composed of purified pollen cytoplasm extracts. Recent experimental data revealed that estrogens might trigger a further proliferative effect on breast cancer cells via the progesterone receptor membrane component-1 (PGRMC1) in addition to the proliferative effect via intracellularly located receptors. MCF-7 and T47D cells were stably transfected with PGRMC1. Different concentrations of the extract alone and in combination with fixed concentrations of estradiol or a growth factor mixture were tested. Proliferation of treated cells was determined by the 3-(4,5-dimethylthiazol-2-yl) 2,5-diphenyl-tetrazolium bromide (MTT)-test and apoptosis was determined using a Cell Death Detection ELISA kit (CDD). Serelys(r) was neutral in the cell lines transfected or not transfected with PGRMC1. It was also neutral in combination with estradiol or growth factors in terms of cell proliferation and cell apoptosis. Thus in contrast to hormone therapy Serelys(r) appears to trigger no further breast cancer risk when applied in the post menopause to women, who do or do not overexpress PGRMC1. Overall Serelys(r) may be an effective alternative for alleviating postmenopausal symptoms without increasing breast cancer risk. PMID- 29179607 TI - Novel pyochelin-based PEGylated liposomes for enhanced delivery of antibiotics against resistant clinical isolates of Pseudomonas aeruginosa. AB - Pseudomonas aeruginosa is a problematic human pathogen resistant to almost all available antibiotics. The important prerequisite for these drugs to target this bacterium is an efficient delivery system. Siderophore-mediated drug delivery system is a promising approach to carry out antibiotics to the cells. Pyochelin, a siderophore of P. aeruginosa, was successfully synthesized in a five-step procedure. PEGylated liposomal pyochelin-antibiotic (L-Pch-Ab) carrier was fabricated by thin-film hydration method. L-Pch-Ab had an average size of 90.31 +/- 0.11 nm holding a negative zeta potential at -54.12 +/- 0.03 mV (PDI <2). The MIC determined by broth dilution method against three clinical strains isolated from burn wounds showed that L-Pch-Ab significantly reduced (<=16 ug/ml) the MIC values than those of free antibiotics. In the time kill assay, L-Pch-Ab was bactericidal against all strains at most time intervals at 2 * and 4 * MIC up to 24 h. TEM observations revealed that L-Pch-Ab was actively taken up by P. aeruginosa and exhibited membrane deformation within 2 h. Developed L-Pch-Ab fused intimately with the outer membrane of MDRPa and exhibited effective antibacterial activity than free Ab. Furthermore, L-Pch-Ab kills MDRPa within infected HaCaT keratinocytes without any cytotoxic effects at 4* MIC concentrations after 72 h. Thus, the specific targeting of L-Pch-Ab with its higher efficacy to deliver drug by limiting the toxicity will be a novel approach to fight infections caused by P. aeruginosa.

AB - We report good outcome after surgical treatment of two patients with meningoencephalocele associated with pharmacoresistant temporal lobe epilepsy. Surgical management of meningoencephaloceles may result in seizure freedom, although optimal surgical strategy is still controversial. PMID- 29179609 TI - Staged pallidotomy: MRI and clinical follow-up in status dystonicus. AB - PURPOSE: We report on a patient affected by Status Distonicus who was treated with Deep Brain Stimulation electrodes implanted in the Globus Pallidus internus (Gpi) and used for serial radiofrequency lesions. MATERIALS AND METHODS: The evolution of radiofrequency lesions was monitored by post-operative and late Magnetic Resonance Imaging (MRI). After the first lesion the patient did improve, though not in a significant fashion. Therefore, three further radiofrequency lesions were delivered 2, 4 and 6 days respectively after surgery with subsequent improvement of dystonic movements. RESULTS: MRI scans performed at 8 days, 3 months, and 6 months after surgery showed a diffuse T2-hyperintense and T1 hypointense GPi signal alteration which progressively decreased over time. CONCLUSION: We confirm that the possibility to stage pallidotomies over time using a couple of new contacts is a safe and efficacious procedure in treating SD patients where the lesions themselves are limited by the appearance of side effects, or in patients showing a poor response to a single lesion. As far as we know, this is the first description of MRI evolution and monitoring of a staged pallidotomy. PMID- 29179610 TI - A Tug-of-War between Cryptochrome and the Visual System Allows the Adaptation of Evening Activity to Long Photoperiods in Drosophila melanogaster. AB - In many animals, the circadian clock plays a role in adapting to the coming season by measuring day length. The mechanism for measuring day length and its neuronal circuits remains elusive, however. Under laboratory conditions, the fruit fly, Drosophila melanogaster, displays 2 activity peaks: one in the morning and one in the evening. These peaks appear to be regulated by 2 separate circadian oscillators (the morning and evening oscillators) that reside in different subsets of pacemaker clock neurons in the brain. The morning and evening activity peaks can flexibly change their phases to adapt to different photoperiods by tracking dawn and dusk, respectively. In this study, we found that cryptochrome (CRY) in the evening oscillators (the fifth small ventral lateral neuron [5th s-LNv] and the dorsal lateral neurons [LNds]) limits the ability of the evening peak to track dusk during long days. In contrast, light signaling from the external photoreceptors (compound eyes, ocelli, and Hofbauer Buchner eyelets) increases the ability of the evening peak to track dusk. At the molecular level, CRY signaling dampens the amplitude of PAR-domain protein 1 (PDP1) oscillations in most clock neurons during long days, whereas signaling from the visual system increases these amplitudes. Thus, our results suggest that light inputs from the two major circadian photoreceptors, CRY and the visual system, have opposite effects on day length adaptation. Their tug-of-war appears to determine the precise phase adjustment of evening activity. PMID- 29179611 TI - Sensitivity to Pigment-Dispersing Factor (PDF) Is Cell-Type Specific among PDF Expressing Circadian Clock Neurons in the Madeira Cockroach. AB - Transplantation studies have pinpointed the circadian clock of the Madeira cockroach to the accessory medulla (AME) of the brain's optic lobes. The AME is innervated by approximately 240 adjacent neuropeptidergic neurons, including 12 pigment-dispersing factor (PDF)-expressing neurons anterior to the AME (aPDFMEs). Four of the aPDFMEs project contralaterally, controlling locomotor activity rhythms of the night-active cockroach. The present in vitro Ca2+ imaging analysis focuses on contralaterally projecting AME neurons and their responses to PDF, GABA, and acetylcholine (ACh). First, rhodamine-dextran backfills from the contralateral optic stalk identified contralaterally projecting AME neurons, which were then dispersed in primary cell cultures. After characterization of PDF, GABA, and ACh responses, PDF immunocytochemistry identified ipsilaterally and contralaterally projecting PDFMEs. All PDF-sensitive clock neurons, PDF immunoreactive clock neurons, and the majority of ipsilaterally and contralaterally projecting cells were excited by ACh. GABA inhibited all PDF expressing clock neurons, and about half of other ipsilaterally projecting and most contralaterally projecting clock neurons. For the first time, we identified PDF autoreceptors in PDF-secreting cockroach circadian pacemakers. The medium sized aPDFMEs and all other contralaterally projecting PDF-sensitive clock cells were inhibited by PDF. The ipsilaterally remaining small PDF-sensitive clock cells were activated by PDF. Only the largest aPDFME did not express PDF autoreceptors. We hypothesize that opposing PDF signaling generates 2 different ensembles of clock cells with antiphasic activity, regulating and maintaining a constant phase relationship between rest and activity cycles of the night-active cockroach. PMID- 29179612 TI - Self-reference enhances relational memory in young and older adults. AB - The present study investigated the influence of self-reference on two kinds of relational memory, internal source memory and associative memory, in young and older adults. Participants encoded object-location word pairs using the strategies of imagination and sentence generation, either with reference to themselves or to a famous other (i.e., George Clooney or Oprah Winfrey). Both young and older adults showed memory benefits in the self-reference conditions compared to other-reference conditions on both tests, and the self-referential effects in older adults were not limited by low memory or executive functioning. These results suggest that self-reference can benefit relational memory in older adults relatively independently of basic memory and executive functions. PMID- 29179613 TI - Reading Fluency and Students With Reading Disabilities: How Fast Is Fast Enough to Promote Reading Comprehension? AB - The goal of improving reading rate and fluency is to positively impact reading comprehension; however, it is unclear how fast students with learning disabilities (LD) need to read to reap this benefit. The purpose of this research was to identify the point of diminishing return for students who were dysfluent readers. Participants included 337 students with reading difficulties in second and fourth grade (61% eligible for special education; 80% with a diagnosis of LD in the area of reading) and 150 typical readers from the same general education classes. LOESS (LOcal regrESSion) plots (logistic regression) were used to determine where linear relations between reading rate and comprehension broke down for these students: the rate at which getting faster no longer contributed clearly to reading comprehension improvement. Although typical readers in this sample showed patterns of oral reading rate and comprehension similar to students in other studies, patterns for students with reading difficulties differed. For dysfluent readers, improving reading rate improved comprehension only in the bands between 35 and 75 words correct per minute in second grade and between 40 and 90 words correct in fourth grade. Reading at faster rates revealed no clear advantage for reading comprehension.

AB - The incidence and mortality rate of colorectal cancer (CRC) have been significantly increasing. However, mechanisms involved in CRC progression are still unclear. LncRNA ZFAS1 has been verified as oncogenic molecular in a series of tumors, including CRC. However, the underlying mechanism of ZFAS1 in CRC carcinogenesis remains unclear. In the present study, our data showed that ZFAS1 expression was significantly upregulated in CRC tissues and cell lines. Correlation analysis showed that high ZFAS1 expression was significantly associated with Helicobacter pylori infection, lymph nodes metastasis, advanced TNM stage and poor overall survival of CRC patients. Loss-of-function experiments revealed that ZFAS1 inhibition could markedly suppress CRC cells proliferation and invasion both in vitro and in vivo. Bioinformatics analysis and luciferase reporter assay revealed that ZFAS1 directly interacted with miR-484. Rescue experiments showed that miR-484 inhibitor reversed the tumor suppressing roles of ZFAS1 knockdown on CRC cells. Therefore, our study suggested that ZFAS1 could act as an oncogene in CRC tumorigenesis, and discovered the functional regulatory pathway of ZFAS1 sponging miR-484. PMID- 29179615 TI - Phenolic metabolites, biological activities, and isolated compounds of Terminalia muelleri extract. AB - CONTEXT: Terminalia muelleri Benth. (Combretaceae), is rich with phenolics that have antioxidant and cytotoxic activities. No screening studies were published before on T. muelleri. OBJECTIVE: The study focused on isolation and identification of secondary metabolites from aqueous methanol leaf extract of T. muelleri and evaluation of its biological activities. MATERIALS AND METHODS: The n-butanol extract was chromatographed on polyamide 6, and eluted with H2O/MeOH mixtures of decreasing polarity, then separated by different chromatographic tools that yielded 10 phenolic compounds. The antioxidant activity of the extract was evaluated by investigating its total phenolic and flavonoid content and DPPH scavenging effectiveness. The extract and the two acylated flavones were evaluated for their anticancer activity towards MCF-7 and PC3 cancer cell lines. Molecular docking study of the acylated flavones was performed against topoisomerase enzyme. RESULTS AND DISCUSSION: Two acylated flavonoids, apigenin-8 C-(2"-O-galloyl) glucoside 1 and luteolin-8-C-(2"-O-galloyl) glucoside 2, were isolated and identified for the second time in nature, with eight tannins (3-10), from the leaves of T. muelleri. The extract and compound 10 showed the most significant antioxidant activity (IC50 = 3.55 and 6.34 MUg/mL), respectively. The total extract and compound 2 demonstrated cytotoxic effect against MCF-7 with IC50 = 29.7 and 45.2 MUg/mL respectively, while compound 1 showed cytotoxic effect against PC3 (IC50 = 40.8 MUg/mL). The docking study of compounds 1 and 2 confirmed unique binding mode in the active site of human DNA topoisomerase enzyme. CONCLUSIONS: Terminalia muelleri is a promising medicinal plant as it possesses high antioxidant activity and moderate cytotoxic activity against MCF 7.

AB - It is unknown whether children with conduct problems (CP) and poor reading (PR) skills exhibit more profound executive function impairments than children with CP only and whether such impairments are explained by coexisting PR. Executive functions were compared in four groups of 7- to 8-year-old children: 26 CP only, 35 PR only, 27 CP-PR, and 31 comparison (COM) children with neither CP nor PR. The Conners' Teacher Rating Scale-28 and a sentence completion reading test were used to assess CP and PR skills. The Wechsler Intelligence Scale for Children Third Edition Backward Digit Span, the Conners' Continuous Performance Test, and the Tower of London were used to assess three aspects of executive function: verbal working memory, response inhibition, and planning, respectively. The CP-PR group had lower verbal working memory than the CP-only and COM groups, but the difference was not significant after intellectual ability, inattention, and hyperactivity were controlled. The CP-PR group made more errors in the planning task (rule violations) than the COM and CP-only groups, but the difference was not significant after intellectual ability was controlled. No significant group differences were found in response inhibition. A specific PR group effect was found for verbal working memory. Children with CP-PR have more prominent executive function impairments that cannot be attributed to coexisting PR. PMID- 29179617 TI - Twelve tips for incorporating and teaching sexual and gender minority health in medical school curricula. AB - The World Health Organization has identified many barriers to improving the health of lesbian, gay, bisexual, and transgender (LGBT) patients, including challenges to incorporating and teaching about healthcare for such patients, which we call "sexual and gender minority" (SGM) health content. These challenges include structural and logistical barriers to incorporating SGM health content into undergraduate medical curricula, as well as lack of support in identifying high-quality pedagogical methods for teaching this material. Here, we provide twelve tips for incorporating and teaching SGM health curricular content in undergraduate medical education, including resources and strategies to support individual educators. Based on our success in developing and implementing this content, we believe that our approach can be effectively used by individual educators aiming to incorporate SGM health curricular material into their teaching, and to support individuals or groups championing the inclusion of a SGM health topical sequence in medical curricula. PMID- 29179618 TI - Trends in research productivity of residents applying for orthopedic sports medicine fellowship. AB - OBJECTIVES: Though there are no research requirements to match into an orthopaedic sports medicine fellowship, many applicants are productive in research endeavors during residency. We hypothesize that the number of publications by Orthopaedic sports medicine applicants are increasing. METHODS: A list of current and recent sports medicine fellows was compiled from publicly accessible information on sports medicine fellowship websites. Articles published while the fellow was a resident were identified via publicly available search engines. The following information was collected: year of fellowship and years of residency, fellowship program, geographic location of fellowship program, total number of publications (noting specifically first and last author publications), number of publications in high impact orthopaedic journals (AJSM, JBJS Am, JSES, or Arthroscopy). RESULTS: Overall, 189 fellowship-matched surgeons from 2010 - 2017 were identified. There were 746 publications (average of 3.95 per fellow), with 218 (29.2%) in high impact orthopaedic journals. Surgeons who completed their fellowship during the 2016-17 academic year, published on average 5.42 publications per fellow. Fellowship applicants in the Northeast region had the highest number of total publications (359 publications, 48.1% of all publications; 6.41 publications per fellow). Applicants were listed most often as middle authors (462 publications, 61.9%). CONCLUSIONS: There has been an overall increase in the number of publications among sports medicine fellowship applicants in the last several academic years. Fellowship programs in the northeast United States tended to match applicants with a higher number of publications. PMID- 29179620 TI - A Novel Method for Quantifying Human In Situ Whole Brain Deformation under Rotational Loading Using Sonomicrometry. AB - Traumatic brain injuries (TBI) are one of the least understood injuries to the body. Finite element (FE) models of the brain have been crucial for understanding concussion and for developing injury mitigation systems; however, the experimental brain deformation data currently used to validate these models are limited. The objective of this study was to develop a methodology for the investigation of in situ three-dimensional brain deformation during pure rotational loading of the head, using sonomicrometry. Sonomicrometry uses ultrasonic pulses to measure the dynamic distances between piezoelectric crystals implanted in any sound-transmitting media. A human cadaveric head-neck specimen was acquired 14 h postmortem and was instrumented with an array of 32 small sonomicrometry crystals embedded in the head: 24 crystals were implanted in the brain, and 8 were fixed to the inner skull. A dynamic rotation was then applied to the head using a closed-loop controlled test device. Four pulses with different severity levels were applied around three orthogonal anatomical axes of rotation. A repeated test of the highest severity rotation was conducted in each axis to assess repeatability. All tests were completed within 56 h postmortem. Overall, the combined experimental and sonomicrometry methods were demonstrated to reliably and repeatedly capture three-dimensional dynamic deformation of an intact human brain. These methods provide a framework for using sonomicrometry to acquire multidimensional experimental data required for FE model development and validation, and will lend insight into the deformations sustained by the brain during impact. PMID- 29179619 TI - Urban fine particulate matter (PM2.5) exposure destroys blood-testis barrier (BTB) integrity through excessive ROS-mediated autophagy. AB - CONTEXT: Blood-testis barrier (BTB), constituted by tight junctions (TJs), adherens junctions and gap junctions, is important for spermatogenesis. PM2.5 is known to impair testicular functions and reproduction. However, its effects on BTB and the underlying mechanisms remain obscure. OBJECTIVE: To investigate the roles of autophagy in BTB toxicity induced by PM2.5. MATERIALS AND METHODS: Sprague-Dawley rats were developmentally exposed to normal saline (NS) or PM2.5 with the doses of 9 mg/kg b.w. and 24 mg/kg b.w. via intratracheal instillation for seven weeks. Success rate of mating, sperm quality, testicular morphology, expressions of BTB junction proteins and autophagy-related proteins were detected. In addition, expressions of oxidative stress markers were also analyzed. RESULTS: Our results demonstrated that developmental PM2.5 exposure induced noticeable decreased fertility, significantly reduced sperm count, increased sperm abnormality rate and severe testicular damage in histomorphology. The expressions of TJ (such as ZO-1 and occludin), gap junction (such as connexin43) were down-regulated significantly after PM2.5 treatment. Intriguingly, PM2.5 simultaneously increased the number of autophagosomes and the levels of autophagy marker LC3-II and p62, suggesting that the accumulated autophagosomes resulted from impaired autophagy degradation. Moreover, the expressions of HO-1 levels remarkably increased and expression levels of Gpx and SOD were significantly decreased after PM2.5 exposure. Vitamins E and C could alleviate the PM2.5-induced oxidative stress, reverse the autophagy defect and restore the BTB impairment. CONCLUSIONS: Taken together, the results suggest that PM2.5 exposure destroys BTB integrity through excessive ROS-mediated autophagy. Our finding could contribute to a better understanding of PM2.5-induced male reproductive toxicity. PMID- 29179621 TI - Erythropoietin Attenuates the Brain Edema Response after Experimental Traumatic Brain Injury. AB - Erythropoietin (EPO) has neuroprotective effects in multiple central nervous system (CNS) injury models; however EPO's effects on traumatic brain edema are elusive. To explore EPO as an intervention in traumatic brain edema, male Sprague Dawley (SD) rats were subjected to blunt, controlled traumatic brain injury (TBI). Animals were randomized to EPO 5000 IU/kg or saline (control group) intraperitoneally within 30 min after trauma and once daily for 4 consecutive days. Brain MRI, immunohistofluorescence, immunohistochemistry, and quantitative protein analysis were performed at days 1 and 4 post- trauma. EPO significantly prevented the loss of the tight junction protein zona occludens 1 (ZO-1) observed in control animals after trauma. The decrease of ZO-1 in the control group was associated with an immunoglobulin (Ig)G increase in the perilesional parenchyma, indicating blood-brain barrier (BBB) dysfunction and increased permeability. EPO treatment attenuated decrease in apparent diffusion coefficient (ADC) after trauma, suggesting a reduction of cytotoxic edema, and reduced the IgG leakage, indicating that EPO contributed to preserve BBB integrity and attenuated vasogenic edema. Animals treated with EPO demonstrated conserved levels of aquaporin 4 (AQP4) protein expression in the perilesional area, whereas control animals showed a reduction of AQP4. We show that post TBI administration of EPO decreases early cytotoxic brain edema and preserves structural and functional properties of the BBB, leading to attenuation of the vasogenic edema response. The data support that the mechanisms involve preservation of the tight junction protein ZO-1 and the water channel AQP4, and indicate that treatment with EPO may have beneficial effects on the brain edema response following TBI. PMID- 29179623 TI - In Defense of the Questionable: Defining the Basis of Research Scientists' Engagement in Questionable Research Practices. AB - National Institutes of Health principal investigators reported their perceptions of the ethical defensibility, prevalence in their field, and their personal willingness to engage in questionable research practices (QRPs). Using ethical defensibility ratings, an exploratory factor analysis yielded a two-factor solution: behaviors considered unambiguously ethically indefensible and behaviors whose ethical defensibility was more ambiguous. In addition, increasing perceptions that QRPs affect science predicted reduced acceptability of QRPs, whereas increasing beliefs that QRPs are normative or necessary for career success predicted increased acceptability of QRPs. Perceptions that QRPs are risky were unrelated to QRP acceptability but predicted reduced extramural funding (i.e., researchers' lifetime extramural grants and total funding secured). These results identify risk (i.e., beliefs that QRPs are normative to stay competitive in one's field) and protective factors (i.e., beliefs that QRPs have a significant negative impact on society) related to QRP endorsement that could inform educational interventions for training research scientists. PMID- 29179622 TI - Traumatic Brain Injury Impairs Myogenic Constriction of Cerebral Arteries: Role of Mitochondria-Derived H2O2 and TRPV4-Dependent Activation of BKca Channels. AB - Traumatic brain injury (TBI) impairs autoregulation of cerebral blood flow, which contributes to the development of secondary brain injury, increasing mortality of patients. Impairment of pressure-induced myogenic constriction of cerebral arteries plays a critical role in autoregulatory dysfunction; however, the underlying cellular and molecular mechanisms are not well understood. To determine the role of mitochondria-derived H2O2 and large-conductance calcium activated potassium channels (BKCa) in myogenic autoregulatory dysfunction, middle cerebral arteries (MCAs) were isolated from rats with severe weight drop impact acceleration brain injury. We found that 24 h post-TBI MCAs exhibited impaired myogenic constriction, which was restored by treatment with a mitochondria-targeted antioxidant (mitoTEMPO), by scavenging of H2O2 (polyethylene glycol [PEG]-catalase) and by blocking both BKCa channels (paxilline) and transient receptor potential cation channel subfamily V member 4 (TRPV4) channels (HC 067047). Further, exogenous administration of H2O2 elicited significant dilation of MCAs, which was inhibited by blocking either BKCa or TRPV4 channels. Vasodilation induced by the TRPV4 agonist GSK1016790A was inhibited by paxilline. In cultured vascular smooth muscle cells H2O2 activated BKCa currents, which were inhibited by blockade of TRPV4 channels. Collectively, our results suggest that after TBI, excessive mitochondria-derived H2O2 activates BKCa channels via a TRPV4-dependent pathway in the vascular smooth muscle cells, which impairs pressure-induced constriction of cerebral arteries. Future studies should elucidate the therapeutic potential of pharmacological targeting of this pathway in TBI, to restore autoregulatory function in order to prevent secondary brain damage and decrease mortality. PMID- 29179624 TI - Invited Commentary on Dube et al. (Perceptions of Equipoise, Risk/Benefit Ratios, and "Otherwise Healthy Volunteers" in the Context of Early-Phase HIV Cure Research in the United States-A Qualitative Inquiry): Are HIV-Infected Candidates for Participation in Risky Cure-Related Studies Otherwise Healthy? PMID- 29179625 TI - The Ethics of Health Care Delivery in a Pediatric Malaria Vaccine Trial: The Perspectives of Stakeholders From Ghana and Tanzania. AB - This study explores ethical issues raised in providing medical care to participants and communities of low-resource settings involved in a Phase II/III pediatric malaria vaccine trial (PMVT). We conducted 52 key informant interviews with major stakeholders of an international multi-center PMVT (GSK/PATH-MVI RTS,S) (NCT00866619) in Ghana and Tanzania. Based on their stakeholder experiences, the responses fell into three main themes: (a) undue inducement, (b) community disparities, and (c) broad therapeutic misconceptions. The study identified the critical ethical aspects, from the perspectives of stakeholders, of delivering health care during a PMVT. The study showed that integrating research into health care services needs to be addressed in a manner that upholds the favorable risk-benefit ratio of research and attends to the health needs of local populations. The implementation of research should aim to improve local standards of care through building a collaborative agenda with local institutions and systems of health. PMID- 29179626 TI - Reply to Commentary: "Are HIV-Infected Candidates for Participation in Risky Cure Related Studies Otherwise Healthy?" AB - We respond to Eyal et al.'s commentary focusing on how people living with HIV participating in HIV cure-related studies are defined. We argue that the types of participants enrolled in research cannot be dissociated from the study interventions, the types of anticipated risks, and the background standard of care. As the field of HIV cure research advances, more nuance and granularity will be needed to define research criteria and acceptable risk/benefit ratios for cure study participants, as well as specific tiered protocol designs that serve to protect various participant populations from untoward risks, especially in very early phase research with interventions known to have potentially serious toxicities. We highlight key lessons from the ACTIVATE study involving a latency reversing agent, Panobinostat, for HIV cure study design involving "otherwise healthy volunteers". PMID- 29179627 TI - Delirium is associated with increased mortality in the geriatric population. AB - OBJECTIVE: The aim of this study was to investigate the prevalence of delirium and its association with mortality rates in elderly inpatients. METHODS: The medical records of 1435 patients over 65 years old who were treated at a regional university hospital and were referred to the university's Consultation and Liaison Psychiatry Clinic for psychological evaluation were retrospectively analyzed. Patients with and without a diagnosis of delirium were compared. The National Survival Database was used to determine mortality rates. RESULTS: The prevalence of delirium was 25.5%. The delirium group was older (p < .0001) and had a larger proportion of males (p < .0001). Mortality rate was higher in the delirium group at 1, 2, 3, 4, and 5 years (p < .0001 for all). Age, gender, lower urinary system diseases, chronic liver disease, solid hematologic malignancy, infections, and Alzheimer's disease emerged as significant parameters associated with mortality. Multivariate analysis of these parameters indicated that comorbid diseases (lower urinary system diseases, chronic liver disease, solid hematologic malignancy, infections, and Alzheimer's disease) are risk factors for mortality independent of demographic data such as age and gender. CONCLUSIONS: Independent of all other factors, delirium is associated with higher mortality risk. PMID- 29179628 TI - Pregnancy after uterine artery embolization using GelfoamTM. AB - We present a case study of a patient who underwent uterine artery embolization (UAE) using GelfoamTM (Pfizer, New York, NY, USA) and had a subsequent pregnancy. Our patient, a 38-year-old female (4 Gravida/2 Para), underwent UAE for treatment of symptomatic myoma in September 2005. At the patient's seven-month post procedure visit, she experienced a 43.9% volume reduction in uterine size and 74.5% reduction in volume of the largest fibroid and relief of bulk symptoms and menorrhagia. The patient had a term delivery of healthy twin infants 15 months post embolization. PMID- 29179630 TI - Joining, belonging, and re-valuing: a process of meaning-making through group participation in a mental health lifestyle intervention. AB - BACKGROUND: Balancing Everyday Life (BEL), a new group-based intervention for mental health service users, was implemented in Sweden. Mental health service users often experience group interventions as meaningful, but knowledge of the process of meaning-making in a group is lacking. AIM: To explore participants' perceptions of the group in the Balancing Everyday Life (BEL) lifestyle intervention; specifically, personal experiences of what brings meaning when participating in a group. METHODS: This qualitative Grounded Theory study included 26 interviews with 19 BEL participants. RESULTS: A process of meaning making in a group was constructed: Joining with others: from feeling alone to connected, A sense of belonging: mutual support and understanding, and Re-valuing Self: respect and self-worth. No longer feeling alone contributed to meaning. Peers and group leaders were considered important parts of the group, and participants appreciated feeling understood, respected, and helping others. CONCLUSION: The proposed process of meaning-making, as well as 'Joining' as a unique step, seems to be new contributions which could help practitioners when organizing groups. Overcoming fear of joining could break a cycle of isolation and lead to connecting and belonging. The value of participants finding purpose through helping others should be further explored. PMID- 29179629 TI - Spinal Cord Injury Disrupts Resting-State Networks in the Human Brain. AB - Despite 253,000 spinal cord injury (SCI) patients in the United States, little is known about how SCI affects brain networks. Spinal MRI provides only structural information with no insight into functional connectivity. Resting-state functional MRI (RS-fMRI) quantifies network connectivity through the identification of resting-state networks (RSNs) and allows detection of functionally relevant changes during disease. Given the robust network of spinal cord afferents to the brain, we hypothesized that SCI produces meaningful changes in brain RSNs. RS-fMRIs and functional assessments were performed on 10 SCI subjects. Blood oxygen-dependent RS-fMRI sequences were acquired. Seed-based correlation mapping was performed using five RSNs: default-mode (DMN), dorsal attention (DAN), salience (SAL), control (CON), and somatomotor (SMN). RSNs were compared with normal control subjects using false-discovery rate-corrected two way t tests. SCI reduced brain network connectivity within the SAL, SMN, and DMN and disrupted anti-correlated connectivity between CON and SMN. When divided into separate cohorts, complete but not incomplete SCI disrupted connectivity within SAL, DAN, SMN and DMN and between CON and SMN. Finally, connectivity changed over time after SCI: the primary motor cortex decreased connectivity with the primary somatosensory cortex, the visual cortex decreased connectivity with the primary motor cortex, and the visual cortex decreased connectivity with the sensory parietal cortex. These unique findings demonstrate the functional network plasticity that occurs in the brain as a result of injury to the spinal cord. Connectivity changes after SCI may serve as biomarkers to predict functional recovery following an SCI and guide future therapy. PMID- 29179631 TI - Bulimic Symptomatology Among Male Collegiate Athletes: A Test of an Etiological Model. AB - We tested Petrie and Greenleaf's psychosocial model in relation to male athletes' bulimic symptomatology. Through structural equation modeling, we cross sectionally examined the direct and indirect effects of general and sport specific appearance pressures, internalization, body satisfaction, drive for muscularity, negative affect, and dietary restraint on bulimic symptomatology. Participants were U.S. male collegiate athletes (N = 698; Mage = 19.87 years) representing 17 sports. With minor respecifications, the model had acceptable fit, and the psychosocial variables explained 48% of the bulimic symptomatology variance. Although all variable paths were significant, sport pressures, such as from coaches and teammates about weight, importance of appearance, and looking good in a uniform, were the most salient latent variable. Athletes' engagement in muscle-building behaviors added uniquely and substantively as well. Our analysis begins to clarify the complex interactions among these psychosocial variables in understanding male athletes' bulimic symptomatology and provides a base from which to develop prevention programming. PMID- 29179632 TI - Prediction of the ablated area prior to radiofrequency ablation for liver tumor under CT guidance. AB - PURPOSE: To evaluate the usefulness of a method we developed to predict the ablation area at the time of CT guided radiofrequency (RF) ablation for liver tumors on a CT workstation. MATERIAL AND METHODS: Ten tumors (mean diameter 15.5 mm, range, 9.0-21.5 mm) in seven patients with hepatocellular carcinoma for which CT guided RF ablation was performed were subjects of this study. After advancing the electrode, plain CT was obtained. Then a simulated ball to predict the ablated area was created on the workstation. After confirming that the tumor was sufficiently within the ball, ablation was performed. The distance of the edge of the actual ablated area from that of the predicted ablated area was measured at six points in three cross-sectional directions on CT images after ablation. RESULTS: The procedures were successfully performed without complications. No local recurrence occurred. Mean absolute value of the distance of the gap between the actual and predicted ablated areas was 3.06 +/- 2.18 mm (range: 0 to 9 mm). At 29 (55.8%) points, the actual ablated area was smaller than the predicted ablated area; it was larger in 17 (32.7%), and was the same in 6 (11.5%) points. CONCLUSION: Our method produces an acceptable simulation during RF ablation under CT guidance. PMID- 29179633 TI - A concept for electromagnetic navigated targeting of liver tumors using an angiographic approach. AB - BACKGROUND: The benefits of using navigation technology for percutaneous local ablation of selected hepatocellular carcinoma (HCC) have been shown. Due to additional efforts in the procedural workflow, barriers to introducing navigation systems on a broad clinical level remain high. In this work, initial steps toward a novel concept for simple and precise targeting of HCC are evaluated. MATERIAL AND METHODS: The proposed technique is based on an angiographic approach using an intrahepatic electromagnetic (EM) reference, for consecutive percutaneous navigated positioning of ablation probes. We evaluated the environmental influence of the angiography suite on EM tracking accuracy, the measurement of a 3 D offset from two 2 D fluoroscopy images, and the accuracy and efficiency of the proposed approach in a porcine liver model. RESULTS: The C-arm had a major influence on EM tracking accuracy, with an error up to 3.8 mm. The methodology applied for measurement of a 3 D offset from 2 D fluoroscopy images was confirmed to be feasible with a mean error of 0.76 mm. In the porcine liver model experiment, the overall target positioning error (TPE) was 2.0 mm and time for navigated targeting was 17.9 seconds, when using a tracked ablation probe. CONCLUSIONS: The initial methodology of the proposed technique was confirmed to be feasible, introducing a novel concept for simple and precise navigated targeting of HCC. PMID- 29179634 TI - Azacytidine in combination with tyrosine kinase inhibitors induced durable responses in patients with advanced phase chronic myelogenous leukemia. AB - Although the tyrosine kinase inhibitor (TKI) era has brought great improvement in outcome in chronic myelogenous leukemia (CML), prognosis of accelerated phase or myeloid blast crisis patients or of de novo Philadelphia chromosome-positive acute myeloid leukemia remains poor. We conducted a retrospective study on patients with advanced phase disease treated with a TKI and azacytidine. Sixteen patients were eligible. Median age was 64.9 years, the median number of previous therapies was 2.5 lines, and median follow-up was 23.1 months. Hematologic response (HR) rate was 81.3%. Median overall survival (OS), event free survival and relapse-free survival (RFS) were 31.5, 23.3, and 32.2 months, respectively. All except one patient were treated as out-patients after the first cycle. Five patients were bridged to allogenic hematopoietic stem cells transplant. The combination of a TKI and azacytidine is a safe and efficient regiment for patients with CML patients in advanced phases. PMID- 29179635 TI - The impact of informed self-assessment on the development of medical students' learning goals. AB - PURPOSE: This study investigates the contributions of self-assessment (SA) and external feedback on the development of learning goals (LG) and the influence on LG recall and implementation in medical students. METHODS: Following a standardized patient (SP) assessment, 168 pre-clinical medical students completed a SA, received SP feedback and created a LG. LG were categorized by source. Two weeks later, students recalled LG and described implementation. Chi-squared analyses were used to test the associations. RESULTS: SA influenced LG for 82.8% of students whereas SP feedback influenced LG for 45.9%. Students rarely generated LG based on SA when they received discordant feedback (5.4%), but sometimes incorporated feedback discordant from their SA into LG (14.9%). Students who created LG based on SP feedback were more likely to recall LG than those who created LG based on SA, 89.7 versus 67.6%, p < 0.05 and implement their LG, 72.4 versus 48.9%, chi2(1) = 5.3, p = 0.017. Students who reported receiving effective feedback were more likely to implement their LG than those reporting adequate feedback, 60.9 versus 37.9%, chi2(1) = 8.0, p = 0.01. CONCLUSIONS: SA is an essential part of goal setting and subsequent action. Perception of feedback plays a crucial role in LG implementation. PMID- 29179636 TI - Development and in vitro/in vivo evaluation of artemether and lumefantrine co loaded nanoliposomes for parenteral delivery. AB - Combination therapy of artemether (ART) and lumefantrine (LUM) is well established for the treatment of uncomplicated malaria worldwide. Nanoliposomes (NLs) encapsulating both drugs were prepared and freeze-dried. The lyophilized nanoliposomes exhibited high entrapment efficiency of artemether (66.18%), relatively low entrapment efficiency of lumefantrine (53.46%), low average size diameter (125.3 nm) and found to be stable at 4 degrees C for 60 days without significant change in mean particle diameter and drug entrapment efficiencies. In vitro drug release study has shown initial burst effect and then sustained release pattern over a time period of 30 h. In vivo toxicity study was examined by liver and kidney function test as well as histopathological examination. Nanoliposomes showed lower hemolytic potential (~10%) compared to all the components when studied individually. There was no significant change (p > 0.05) in biochemical parametes between control and treated group of animals. Pharmacokinetic data of ART + LUM NLs showed higher the area under the plasma concentration-time curve (AUC) values and prolonged residence time of drug in the blood circulation compared with ART + LUM solution. The tissue distribution demonstrated high uptake of ART + LUM-NLs in RES organs particularly in liver and spleen. Biocompatibility was confirmed by hepato- and nephrotoxicity analysis showed no sign of fibrosis, fatty infiltration, centrilobular necrosis and lymphocyte infiltration confirmed the suitability of developed formulation for treatment of malaria. PMID- 29179638 TI - The Hobnail Variant of Papillary Thyroid Carcinoma: Clinical/Molecular Characteristics of a Large Monocentric Series and Comparison with Conventional Histotypes. AB - BACKGROUND: The hobnail variant of papillary thyroid carcinoma (HPTC) has an aggressive behavior. The aims of this prospective study were to define the clinical/molecular characteristics of HPTC, and to compare them to those of conventional papillary thyroid carcinoma (PTC). METHODS: From 2010 to 2016, 25 cases of HPTC, characterized clinically and molecularly (BRAF, RAS, TERT promoter, and TP53 mutations), were compared to a series of 165 consecutive cases of PTC. All patients underwent total thyroidectomy and received radioactive iodine treatment. Follow-up was available for 19 HPTC patients. RESULTS: Among the HPTC patients, 64% had a hobnail component >=30%, and 64% had multifocal disease. The mean tumor size was 30 mm; 96% of tumors were angio-invasive; 68% were N1, and 12% were M1; 58% harbored the BRAFV600E mutation, 12% had a mutation in the TERT promoter, 17% had a TP53 mutation, and not had a RAS mutation. At a mean follow-up of 39 months, 32% of patients had biochemical and/or structural disease. Tumor size was the only significant difference between patients with persistent disease and those with an excellent response (40 mm and 24 mm, respectively; p = 0.02). Compared to the PTC control group, the HPTC patients had larger tumors (30 mm vs. 16 mm; p < 0.001), more frequent lymph node involvement (68% vs. 38%; p = 0.01), and remote disease (16% vs. 3%; p < 0.0001), a similar prevalence of the BRAFV600E mutation (58% vs. 59%), a higher prevalence of TP53 mutations (17% vs. 1%; p < 0.05), and a worse outcome (structural/biochemical disease: 32% vs. 9%; p < 0.0001). CONCLUSIONS: HPTC is an aggressive variant, characterized by large tumor size, lymph node involvement, a tendency to metastasize, and a worse outcome.

AB - Congenital stationary night blindness 2A (CSNB2A) is an X-linked retinal disorder, characterized by phenotypically variable signs and symptoms of impaired vision. CSNB2A is due to mutations in CACNA1F, which codes for the pore-forming alpha1F subunit of a L-type voltage-gated calcium channel, Cav1.4. Mouse models of CSNB2A, used for characterizing the effects of various Cacna1f mutations, have revealed greater severity of defects than in human CSNB2A. Specifically, Cacna1f knockout mice show an apparent lack of visual function, gradual retinal degeneration, and disruption of photoreceptor synaptic terminals. Several reports have also noted cone-specific disruptions, including axonal abnormalities, dystrophy, and cell death. We have explored further the involvement of cones in our 'G305X' mouse model of CSNB2A, which has a premature truncation, loss-of function mutation in Cacna1f. We show that the expression of genes for several phototransduction-related cone markers is down-regulated, while that of several cellular stress- and damage-related markers is up-regulated; and that cone photoreceptor structure and photopic visual function - measured by immunohistochemistry, optokinetic response and electroretinography - deteriorate progressively with age. We also find that dystrophic cone axons establish synapse like contacts with rod bipolar cell dendrites, which they normally do not contact in wild-type retinas - ectopically, among rod cell bodies in the outer nuclear layer. These data support a role for Cav1.4 in cone synaptic development, cell viability, and synaptic transmission of cone-dependent visual signals. Although our novel finding of cone-to-rod-bipolar cell contacts in this mouse model of a retinal channelopathy may challenge current views of the role of Cav1.4 in photopic vision, it also suggests a potential new target for restorative therapy. PMID- 29179639 TI - Are neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and/or mean platelet volume (MPV) clinically useful as predictive parameters for preeclampsia? AB - OBJECTIVE: Preeclampsia (PE) is a severe pregnancy complication with significant maternal and neonatal morbi-mortality resulting in high health care costs. Prevention, mainly based on the administration of acetylsalicylic acid, is only possible if timely identification of high-risk patients can be realized in an easy, nonexpensive, and widely available method. This paper explores the clinical usability of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and/or mean platelet volume (MPV) in discriminating between women that will and those that will not develop PE. STUDY DESIGN: Demographic data and laboratory results were retrospectively collected and compared in 2050 pregnant women (164 PE and 1886 controls) between 1 January 2014 and 31 January 2016. RESULTS: In the PE group, gravidity, parity, gestational age, and birth weight were significantly lower compared to the control group. Before the 20th pregnancy week, MPV was significantly elevated in the PE group compared to the controls (p = .006), hence analysis revealed an optimal cut-off point of 8.15 (sensitivity 66.7%, specificity 56.3%) for predicting PE. At the end of pregnancy, NLR and MPV appeared to be higher and PLR lower in the PE group compared to the controls, which strengthens the current knowledge on the pathogenesis of PE. CONCLUSIONS: MPV is significantly elevated in the first half of pregnancy in women who later develop PE and might therefore be implemented in combination with other parameters in a PE prediction model. PMID- 29179640 TI - 2,4-Dinitroanisole (DNAN) (2014). AB - 2,4-dinitroanisole (DNAN) is a warhead explosive currently under investigation as a replacement for TNT in melt-cast insensitive munitions. In animal studies, DNAN is a mild ocular and skin irritant with a significant potential for dermal absorption. It is not a dermal sensitizer. Acute and subacute rat inhalation studies demonstrated minimal toxicity with LC50 and LOAEL endpoints of 2.9 and 150 mg/m3, respectively. In rat oral toxicity studies (14 and 90 days) organ weight and clinical chemistry changes suggested hepatocellular injury and anemia, particularly in females. In males there was evidence of testicular injury at the high-dose level (80 mg/kg/day). The NOAELs for the 14- and 90-day studies were 25 and 5 mg/kg/day, respectively, with a calculated BMDL10 value of 0.93 mg/kg/day. No chronic, carcinogenicity or reproductive/developmental toxicity data were available for DNAN, but a maternal and fetal NOAEL of 5.1 mg/kg/day was inferred. DNAN is considered non-mutagenic and non-genotoxic. It is metabolized in vivo to 2,4-dinitrophenol (DNP), but other details of its metabolism or pharmacokinetics are unknown. There are considerable toxicity data for DNP, a known un-coupler of oxidative phosphorylation among other things, and these data may further inform regarding the safety of DNAN. In humans, DNAN was a component of louse powder (prior to DDT) with no reported safety concerns. However, its handling and use as a munition component presents a potential occupational hazard by both inhalation and dermal routes of exposure. Considering both DNAN and DNP toxicity endpoints, the recommended Workplace Environmental Exposure limit for DNAN is 0.1 mg/m2 (8-h time weighted average). PMID- 29179641 TI - Microalgal process-monitoring based on high-selectivity spectroscopy tools: status and future perspectives. AB - Microalgae are well known for their ability to accumulate lipids intracellularly, which can be used for biofuels and mitigate CO2 emissions. However, due to economic challenges, microalgae bioprocesses have maneuvered towards the simultaneous production of food, feed, fuel, and various high-value chemicals in a biorefinery concept. On-line and in-line monitoring of macromolecules such as lipids, proteins, carbohydrates, and high-value pigments will be more critical to maintain product quality and consistency for downstream processing in a biorefinery to maintain and valorize these markets. The main contribution of this review is to present current and prospective advances of on-line and in-line process analytical technology (PAT), with high-selectivity - the capability of monitoring several analytes simultaneously - in the interest of improving product quality, productivity, and process automation of a microalgal biorefinery. The high-selectivity PAT under consideration are mid-infrared (MIR), near-infrared (NIR), and Raman vibrational spectroscopies. The current review contains a critical assessment of these technologies in the context of recent advances in software and hardware in order to move microalgae production towards process automation through multivariate process control (MVPC) and software sensors trained on "big data". The paper will also include a comprehensive overview of off-line implementations of vibrational spectroscopy in microalgal research as it pertains to spectral interpretation and process automation to aid and motivate development. PMID- 29179642 TI - A Follow-Up Strategy for Patients with an Excellent Response to Initial Therapy for Differentiated Thyroid Carcinoma: Less Is Better. AB - BACKGROUND: The risk of recurrence in patients with differentiated thyroid cancer (DTC) can be estimated based on their response to initial therapy. The aim of this study was to evaluate an adequate follow-up strategy for DTC patients with an excellent response by assessing the characteristics of structural recurrence. METHODS: This historical cohort study included 1359 DTC patients who had excellent response to total thyroidectomy with radioactive iodine remnant ablation. RESULTS: Among 1359 patients, 703 (54%) patients were classified as stage I according to the seventh tumor node metastasis staging system, and 987 (73%) patients were classified as intermediate risk according to the American Thyroid Association's risk stratification after initial therapy. During a median of 8.7 years of follow-up, only 13 (1%) patients were confirmed to have structural recurrence. All of the recurrences were locoregional disease, and there were no distant metastases. Recurrences were detected late at a median of 5.5 years after the initial surgery (range 3.6-10.7 years). All structural recurrences were detected on neck ultrasonography. Non-stimulated serum thyroglobulin (Tg) was detectable (>=0.2 ng/mL) in four (31%) patients, and serum anti-Tg antibodies were positive in one (8%) patient. However, non-stimulated serum Tg levels were stably low (<0.2 ng/mL) in eight (62%) patients when recurrences were detected. In addition to these 13 patients, 14 patients also presented with biochemical persistent disease at the end of follow-up. CONCLUSIONS: Recurrences of DTC in patients with an excellent response to initial therapy were detected relatively late. The intensity and frequency of follow-up of neck ultrasonography as well as serum Tg and anti-Tg antibody measurements should be reduced, especially within five years of the initial therapy, in DTC patients who have an excellent response. PMID- 29179643 TI - Sample size requirements for learning to classify with high-dimensional biomarker panels. AB - A common problem in biomedical research is to calculate the sample size required to learn a classifier using a (possibly high-dimensional) panel of biomarkers. This paper describes a simple method based on a Gaussian approximation for calculating the predictive performance of the learned classifier given the size of the biomarker panel, the size of the training sample, and the optimal predictive performance (expressed as C-statistic [Formula: see text]) of the biomarker panel that could be obtained if a training sample of unlimited size were available. Under the assumption that the biomarker effect sizes have the same correlation structure as the biomarkers, the required sample size does not depend upon these correlations, but only upon [Formula: see text] and upon the sparsity of the distribution of effect sizes, defined by the proportion of biomarkers that have nonzero effects. To learn a classifier that extracts 80% of the predictive information, the required case sample size varies from about 0.1 cases per variable for a panel with [Formula: see text] and a sparse distribution of effect sizes (such that 1% of biomarkers have nonzero effect sizes) to nine cases per variable for a panel with [Formula: see text] and a diffuse distribution of effect sizes. PMID- 29179644 TI - Frequency and severity of potential drug interactions in a cohort of HIV-infected patients Identified through a Multidisciplinary team. AB - OBJECTIVES: Interactions between antiretroviral treatment (ART) and comedications are a concern in HIV-infected patients. This study aimed to determine the frequency and severity of potential drug-drug interactions (PDDIs) with ART in our setting. METHODS: Observational study by a multidisciplinary team in 1259 consecutive HIV patients (March 2015-September 2016). Data on demographics, toxic habits, comorbidities, and current ART were collected. A structured questionnaire recorded concomitant medications (including occasional and over-the-counter drugs). PDDIs were classified into four categories: (1) no interactions, (2) mild (clinically non-significant), (3) moderate (requiring close monitoring or drug modification/dose adjustment), and (4) severe (contraindicated). STATISTICAL ANALYSIS: chi-square test, logistic regression analysis. RESULTS: In total, 881 (70%) patients took comedication, and 563 (44.7%) had >= PDDI. Forty-one comedicated patients (4.6%) had severe and 522 (59.2%) moderate PDDIs. Moderate PDDIs mainly involved cardiovascular (53.8%) and central nervous system (40.2%) drugs. Independent risk factors for PDDIs were ART containing a boosted protease inhibitor (odds ratio [OR]=9.11, 95% confidence interval [CI] 5.15-16.11; p = 0.0001) and/or non-nucleoside reverse transcriptase (NNRTI) (OR = 4.34, 95%CI 2.49-7.55; p = 0.0001), HCV co-infection (OR = 3.26, 95%CI 2.15-4.93; p = 0.0001), and use of two or more comedications (OR = 3.36, 95%CI 2.27-4.97; p = 0.0001). Adherence and effectiveness of ART were similar in patients with and without PDDIs. The team made 133 recommendations related to comedications (drug change or dose adjustment) or ART (drug switch or change in administration schedule). CONCLUSIONS: Systematic evaluation detected a significant percentage of PDDIs requiring an intervention in HIV patients on ART. Monitoring and advice about drug-drug interactions should be part of routine practice. PMID- 29179645 TI - Efficient baseline utilization for incomplete block crossover clinical trials. AB - Incomplete block crossover trials with period-specific baseline and post-baseline (outcome) measures for each subject are often used in clinical drug development; without loss of generality, we focus on the three-treatment two-period ([Formula: see text]) crossover. Data from such trials are commonly analyzed using a mixed effects model with indicator terms for treatment and period, and an unstructured covariance matrix for the vector of intra-subject measurements. It is well-known that treatment effect estimates from this analysis are complex functions of both within-subject and between-subject treatment contrasts. We caution that the associated type I error rate and power for hypothesis testing can be non trivially influenced by how the baselines are utilized. Specifically, the mixed effects analysis which uses change from baseline as the dependent variable is shown to consistently underperform corresponding analyses in which the outcome is the dependent variable and linear combinations of the baselines are used as period-specific and/or period-invariant covariates. A simpler fixed effects analysis of covariance involving only within-subject contrasts is also described for small sample situations in which the mixed effects analyses can suffer from increased type I error rates. Theoretical insights, simulation results and an illustrative example with real data are used to develop the main points. PMID- 29179646 TI - Practical Initial Risk Stratification Based on Lymph Node Metastases in Pediatric and Adolescent Differentiated Thyroid Cancer. AB - BACKGROUND: Data on the risk stratification of pediatric differentiated thyroid cancer (DTC) remain scarce. This study aimed to evaluate the predictors of structural persistent/recurrent disease and revise an initial risk-stratification system in pediatric DTC patients. METHODS: This retrospective cohort study included 203 patients (aged <20 years) from two tertiary referral centers in Korea. The extent of cervical lymph node (LN) metastasis was classified based on the location or number of metastatic LNs. RESULTS: During a median follow-up duration of 5.5 years, structural persistent/recurrent disease was observed in 51 (25%) patients, including 22 (11%) with distant metastases. The presence of extrathyroidal extension (ETE) and lateral cervical LN metastases or more than five metastatic LNs were independent predictors for structural persistent/recurrent disease. The presence of bilateral lateral cervical LN metastases or >10 metastatic LNs were independent predictors for distant metastasis. A total of 67 (33%), 72 (35%), and 64 (32%) patients were classified into the low-, intermediate-, and high-risk groups, respectively, based on the presence of ETE and the extent of cervical LN metastases. Compared to the low risk group, the intermediate- and high-risk groups had a significantly greater risk of structural persistent/recurrent disease (hazard ratio = 7.32, p = 0.008, and hazard ratio = 24.28, p < 0.001, respectively). CONCLUSIONS: This revised initial risk-stratification system based on the presence of ETE and the extent of cervical LN metastasis is useful for predicting the clinical outcomes of pediatric DTC patients. The findings could facilitate the practical use of a risk stratification system. PMID- 29179647 TI - Efficacy of group psychotherapy for posttraumatic stress disorder: Systematic review and meta-analysis of randomized controlled trials. AB - OBJECTIVE: The present meta-analysis evaluates the efficacy of group psychotherapy for post-traumatic stress disorder (PTSD) in adults directly compared to no treatment or active treatments examined in randomized controlled trials (RCTs). METHOD: Electronic databases were searched for eligible studies. Effects on PTSD symptoms, depression, and anxiety were extracted. Between- and within-group effect sizes (Hedges' g) were calculated using a random-effects model. Data were adjusted to account for dependencies among observations in groups. RESULTS: Twenty RCTs were included comprising 2244 individuals. Results showed significant effects of group psychotherapy in reducing symptoms of PTSD compared to no-treatment control groups (k = 13; g = 0.70; 95% CI: 0.41; 0.99). No significant differences in efficacy were found between group psychotherapy and other active treatments (k = 8; g = 0.13; 95% CI: -0.16; 0.42). Moderator analyses confirmed gender and trauma type as important moderators of within treatment effects for PTSD. CONCLUSIONS: Group treatments are associated with improvements in symptoms of PTSD. Particularly, the efficacy of exposure-based cognitive-behavioral group therapy (group CBT) is empirically well demonstrated. Still little is known about the effects of group treatment approaches other than CBT and the comparative efficacy to alternative treatments such as individual therapy or pharmacotherapy. PMID- 29179648 TI - Sex Differences in Thermal, Stress, and Inflammatory Responses to Minocycline Administration in Rats with Traumatic Brain Injury. AB - Persistent inflammation, mediated in part by increases in cytokines, is a hallmark of traumatlc brain injury (TBI). Minocycline has been shown to inhibit post-TBI neuroinflammation in male rats and mice, but has not been tested in females. Here, we studied sex differences in thermal, stress, and inflammatory responses to TBI and minocycline. Female rats were ovariectomized under isoflurane anesthesia at 33-36 days of age. At 45-55 days of age, male and female rats were implanted intraperitoneally (i.p.) with calibrated transmitters for monitoring body temperature. Moderate cortical contusion injury (CCI) or sham surgery was performed when the rats attained 60-70 days of age. One hour after surgery, rats were injected i.p. with minocycline (50 mg/kg) or saline (0.3 mL); injections were repeated once daily for the next 3 days. At 28 days after CCI or sham surgery, 30 min restraint stress was initiated and blood samples were obtained by tail venipuncture before the onset of restraint and at 30, 60, and 90 min after stress onset. At 35 days after CCI or sham surgery, rats were decapitated and blood was collected for corticosterone (CORT) and cytokine analysis. The brains were removed and ipsilateral cortical tissue and hippocampus were dissected and subsequently assayed for interleukin (IL)-1beta, IL-6, and tumor necrosis factor (TNF)-alpha. Hyperthermia occurred during days 1-6 post-CCI in male rats, but only on the day of CCI in female rats, and minocycline prevented its occurrence in both sexes. Minocycline facilitated suppression of the CORT response to restraint stress in both sexes. In females, but not males, hippocampal IL-6 content increased post-CCI compared with sham-injured controls, whereas IL-1beta content was augmented by minocycline. Hippocampal TNF-alpha was unaffected by CCI and minocycline. These results demonstrate sex differences in immediate thermal and long-lasting stress and cytokine responses to CCI, and only short-term protective effects of minocycline on hyperthermia. PMID- 29179649 TI - Mesenchymal Stem Cells for Frailty? AB - Frailty is a medical syndrome associated with advancing age characterized by reduced functional reserve, strength, endurance, and susceptibility to infection associated with high morbidity, hospitalization, and death. Nonspecific interventions to improve the healthspan of affected patients include physical therapy, exercise, improved nutrition, etc. Among the hallmarks of aging, depletion of stem cells with resultant compromise of regeneration and repair of tissues informs a rational stem cell-based replacement strategy. This hypothesis has been evaluated in a randomized, double-blind, placebo-controlled clinical trial utilizing human allogeneic mesenchymal stem cells (allo-hMSCs), a facile, scalable stem cell replacement therapy. Intravenous infusion of 100 or 200 million allo-hMSCs was deemed safe in aged frail individuals. However, modest improvement outcomes were limited to the lower dose, a finding that remains difficult to explain. Future studies are definitely warranted given the magnitude of this increasingly important medical syndrome. PMID- 29179650 TI - Statin related adverse effects and patient education: a study from resource limited settings. AB - BACKGROUND: Statins are the most widely prescribed class of drugs for coronary artery disease (CAD) patients and yet literature on the prevalence of statin related adverse effects (AEs) and gaps in patient education is quite limited especially in resource-limited settings of developing world. OBJECTIVES: The present study was conducted to determine the prevalence of myopathy (muscle ailments) and other statin associated adverse effects among CAD patients on statin therapy. The study also aimed to assess patient perceptions, attitudes and awareness concerning the use of statins. METHODS: It was a cross-sectional study conducted among 300 adult CAD patients visiting the out-patient department of a tertiary care hospital in North India, who were receiving statins for their diagnosis. An interviewer administered questionnaire was used to collect data on statin use among patients and adverse effects experienced. RESULTS: Myopathy or muscle related ailments like muscle pain, cramps and muscle weakness were the most prevalent (32, 34 and 47%, respectively), followed by numbness, tingling and burning in the extremities (31%). Joint pain and cognitive impairments were seen in nearly 20% of the patients. The level of awareness among participants regarding the use of statins was sub-optimal. Lack of knowledge and under reporting of adverse effects were major concerns. CONCLUSION: The study shows that a considerable proportion of statin users experience adverse effects and knowledge and awareness amongst patients is inadequate. Awareness programmes and counselling for patients, sensitisation of healthcare professionals and better screening systems for monitoring AEs can help improve the scenario. PMID- 29179651 TI - Endovascular Therapy of the Superficial Femoral Artery Via a Stand-Alone Transradial Access: A Single-Center Experience. AB - OBJECTIVE: We describe our experience in transradial recanalization of the superficial femoral artery (SFA), and we provide a stepwise approach accounting for the patient's height and optimizing the yield of currently available devices. METHODS AND RESULTS: Fifteen patients with simple SFA disease, including 4 patients with total SFA occlusions <15 cm, were selected for stand-alone transradial recanalization. A 6F, 125-cm multipurpose guiding catheter was used to cannulate the limb of interest and support device delivery. The procedure was successful in all patients and consisted of balloon angioplasty (using 0.014", 200-cm shaft monorail balloons) in all patients, and orbital atherectomy in 6 patients. We illustrate the steps and challenges of the transradial approach, namely the limited support in complex disease and the limited reach of current equipment. CONCLUSION: In patients with simple SFA disease, transradial recanalization appears feasible and safe but currently limited to balloon angioplasty +/- orbital atherectomy. Proximal SFA stenting may be feasible in patients <160 cm in height. PMID- 29179652 TI - The effectiveness of an occlusal disclosure sheet to diagnose sleep bruxism: A pilot study. AB - Objective To evaluate the utility of vacuum-pressed, BruxChecker(r) sheets for the diagnosis of sleep bruxism. Methods Twenty subjects participated in this study. Tooth contact during sleep was recorded using a 0.1 mm-thick polyvinyl chloride sheet called BruxChecker(r). The area of the BruxChecker(r) in which the red dye was removed was measured. In addition, the EMG activity of the masseter muscle during sleep was recorded. The numbers of bruxism bursts and episodes were counted, and their correlations with the peeled area of the red dye on the BruxChecker(r) were evaluated. Results The number of bruxism bursts and episodes/hr significantly correlated with the peeled area at all cut-off values. The peeled area significantly correlated with the number of phasic type bruxism episodes but not with tonic or mixed type bruxism episodes. Discussion Since the BruxChecker(r) peeled area reflected phasic type sleep bruxism, the sheets may be useful in sleep bruxism screening. PMID- 29179653 TI - Walk this way: validity evidence of iphone health application step count in laboratory and free-living conditions. AB - Several attempts have been made to demonstrate the accuracy of the iPhone pedometer function in laboratory test conditions. However, no studies have attempted to evaluate evidence of convergent validity of the iPhone step counts as a surveillance tool in the field. This study takes a pragmatic approach to evaluating Health application derived iPhone step counts by measuring accuracy of a standardized criterion iPhone SE and a heterogeneous sample of participant owned iPhones (6 or newer) in a laboratory condition, as well as comparing personal iPhones to accelerometer derived steps in a free-living test. During lab tests, criterion and personal iPhones differed from manually counted steps by a mean bias of less than +/-5% when walking at 5km/h, 7.5km/h and 10km/h on a treadmill, which is generally considered acceptable for pedometers. In the free living condition steps differed by a mean bias of 21.5% or 1340 steps/day when averaged across observation days. Researchers should be cautioned in considering the use of iPhone models as a research grade pedometer for physical activity surveillance or evaluation, likely due to the iPhone not being continually carried by participants; if compliance can be maximized then the iPhone might be suitable. PMID- 29179654 TI - Futility for subgroup analyses in the adaptive signature design. AB - Subgroup analyses in clinical trials are becoming increasingly important. In cancer research, more and more targeted therapies are explored from which probably only a portion of the whole population will benefit. An adaptive design for subgroup selection with identification of a subgroup, the adaptive signature design, was proposed in the literature. Unfortunately, measuring and validating the variables defining the subgroup (i.e. biomarkers) can be extremely expensive. For this reason, we propose an extension of this design where subgroup analysis is not performed when the overall results suggest that it is unlikely to achieve statistical significance in the subgroup. Avoiding measuring and validating expensive biomarkers in this case can save resources that could be used on more promising research. PMID- 29179655 TI - Robust inference under the beta regression model with application to health care studies. AB - Data on rates, percentages, or proportions arise frequently in many different applied disciplines like medical biology, health care, psychology, and several others. In this paper, we develop a robust inference procedure for the beta regression model, which is used to describe such response variables taking values in (0, 1) through some related explanatory variables. In relation to the beta regression model, the issue of robustness has been largely ignored in the literature so far. The existing maximum likelihood-based inference has serious lack of robustness against outliers in data and generate drastically different (erroneous) inference in the presence of data contamination. Here, we develop the robust minimum density power divergence estimator and a class of robust Wald-type tests for the beta regression model along with several applications. We derive their asymptotic properties and describe their robustness theoretically through the influence function analyses. Finite sample performances of the proposed estimators and tests are examined through suitable simulation studies and real data applications in the context of health care and psychology. Although we primarily focus on the beta regression models with a fixed dispersion parameter, some indications are also provided for extension to the variable dispersion beta regression models with an application. PMID- 29179656 TI - End-to-side neurotization with the phrenic nerve in restoring the function of toe extension: an experimental study in a rat model. AB - The phrenic nerve being transferred to the posterior division of the lower trunk with end-to-end neurorrhaphy is reported to be effective in restoring the function of digit extension in literature. However, the phrenic nerve is extremely important in respiration. We designed an animal experiment to discover whether the phrenic nerve being transferred to the posterior division of the lower trunk with end-to-side neurotization was feasible and provided the theoretical basis. A sum of 36 Sprague-Dawley rats was randomly assigned to one of two groups. In Group A, the phrenic nerve was transferred to the posterior division of the lower trunk with end-to-side neurotization. In Group B, the posterior division of the lower trunk was directly sutured. The results of behavioral assessment, electrophysiology, histology and nerve fiber count and muscle weight at 12 weeks postoperatively were recorded. In Group A, none of the rats experienced tachypnea. The motion of slight toe extension was observed. The results of electrophysiology, histology and nerve fiber count and muscle weight in Group A were not as well as those of Group B, but gradually improved with time. The phrenic nerve being transferred to the posterior division of lower trunk with end-to-side neurotization can partially restore the function of toe extension in a rat model. Whether the function of digit extension can be restored by the phrenic nerve with end-to-side neurotization in humans still needs more practice in clinic. PMID- 29179657 TI - Psychosocial factors predicting risky sexual behaviour among long distance truck drivers in Lagos, Nigeria. AB - Long distance truck drivers (LDTDs) have been identified as one of the groups at higher risk for human immunodeficiency virus (HIV) infection. Understanding how certain social and psychological variables that have a strong theoretical basis contribute to sexual risk behaviour will guide in the implementation process of HIV risk-reduction intervention in the trucking population. In line with the conceptualisation of Information, Motivation and Behavioural skills model, we examined the extent that HIV knowledge, attitude towards condom use, peer support to condom use, perceived vulnerability to HIV/AIDS, and condom use self-efficacy will independently and jointly explain sexual risk behaviours of LDTDs in a haulage company in Lagos, Nigeria. A cross-sectional survey design was used and 154 drivers with ages ranging from 27 to 68 years (M = 44.03, SD = 8.82) completed copies of a questionnaire comprising demographics and measures of psychological variables. Psychological factors that included HIV knowledge, attitude towards condom use, perceived vulnerability to HIV/AIDS, peer support to condom use, and condom use self-efficacy significantly jointly predicted sexual risk behaviours (R2 = .59, F(5, 148) = 42.63; p < .05), by accounting for about 59% of the explained variance in sexual risk behaviours. Social factors that included age, number of years of education, number of wives, number of intercourses in the last three months, number of partners apart from primary partners, and number of weeks spent outside home significantly jointly predicted sexual risk behaviour (R2 = .15, F(6, 147) = 4.39; p < .05) by accounting for about 15% of the explained variance in sexual risk behaviour among the drivers. It is concluded that all the psychological and social factors examined as predictor variables could jointly play important roles in prevention intervention programmes for reducing sexual risk behaviours of LDTDs. Stakeholders should sensitise LDTDs on the need to realise that they are a high-risk group and are more vulnerable to HIV infection; thus, behaviour change is indispensable in their sexual relationships. PMID- 29179658 TI - Short- and long-term effects of divorce and separation on housing tenure in England and Wales. AB - This paper investigates the effects of marital and non-marital separation on individuals' housing tenure in England and Wales. We apply competing risks event history models to data from the British Household Panel Survey and the UK Household Longitudinal Study to analyse the risk of a residential move to different tenure types, for single, married, cohabiting, and separated men and women. Separated individuals are more likely to move and experience a tenure change than those who are single or in a relationship. Among separated people, private renting is the most common outcome of a move; however, women are also likely to move to social renting, whereas men tend to move to homeownership. This pattern persists when we account for time since separation and order of move, indicating a potential long-term effect of separation on housing tenure. This long-term effect is especially pertinent to separated women who cannot afford homeownership. PMID- 29179659 TI - DYRK1A Is a Regulator of S-Phase Entry in Hepatic Progenitor Cells. AB - Hepatic progenitor cells (HPCs) are adult liver stem cells that act as second line of defense in liver regeneration. They are normally quiescent, but in case of severe liver damage, HPC proliferation is triggered by external activation mechanisms from their niche. Although several important proproliferative mechanisms have been described, it is not known which key intracellular regulators govern the switch between HPC quiescence and active cell cycle. We performed a high-throughput kinome small interfering RNA (siRNA) screen in HepaRG cells, a HPC-like cell line, and evaluated the effect on proliferation with a 5 ethynyl-2'-deoxyuridine (EdU) incorporation assay. One hit increased the percentage of EdU-positive cells after knockdown: dual specificity tyrosine phosphorylation regulated kinase 1A (DYRK1A). Although upon DYRK1A silencing, the percentage of EdU- and phosphorylated histone H3 (pH3)-positive cells was increased, and total cell numbers were not increased, possibly through a subsequent delay in cell cycle progression. This phenotype was confirmed with chemical inhibition of DYRK1A using harmine and with primary HPCs cultured as liver organoids. DYRK1A inhibition impaired Dimerization Partner, RB-like, E2F, and multivulva class B (DREAM) complex formation in HPCs and abolished its transcriptional repression on cell cycle progression. To further analyze DYRK1A function in HPC proliferation, liver organoid cultures were established from mBACtgDyrk1A mice, which harbor one extra copy of the murine Dyrk1a gene (Dyrk+++). Dyrk+++ organoids had both a reduced percentage of EdU-positive cells and reduced proliferation compared with wild-type organoids. This study provides evidence for an essential role of DYRK1A as balanced regulator of S-phase entry in HPCs. An exact gene dosage is crucial, as both DYRK1A deficiency and overexpression affect HPC cell cycle progression.

AB - Over 2 million adults in the United States are incarcerated and over 650,000 return to the community each year. This disparate population is known to have an elevated burden of chronic disease and lower socioeconomic status. Medical residency training about care of incarcerated or previously incarcerated patients is significantly lacking in the United States. Curriculum can be developed and implemented in residency programs to help physicians learn how to work with this population, be sensitive to their unique needs, and achieve positive health outcomes. This article describes a method for "educating the educators" based on a workshop presented at a peer-reviewed national conference during the fall of 2016. Attendees participated in exercises addressing assumptions, expectations, bias, and worldview and increased their ability for self-reflection when interacting with patients who are or have experienced incarceration. In this session, strategies were identified that engaged the patient with the goal to aid in patient retention and compliance. Future steps include development of a formal curriculum for training in this area, incorporation into existing community medicine rotations or electives, and establishment of structured transition clinics where residents can be exposed to this population on a more regular basis and improve their overall health outcomes. PMID- 29179661 TI - Psychoactive substance use in specialized psychiatric care patients. AB - Objective Life expectancy of psychiatric patients is markedly shorter compared to the general population, likely partly due to smoking or misuse of other substances. We investigated prevalence and correlates of substance use among psychiatric patients. Methods Within the Helsinki University Psychiatric Consortium Study, data were collected on substance use (alcohol, smoking, and illicit drugs) among patients with schizophrenia or schizoaffective disorder (n = 113), bipolar (n = 99), or depressive disorder (n = 188). Clinical diagnoses of substance use were recorded, and information on smoking, hazardous alcohol use, or misuse of other substances was obtained using questionnaires. Results One fourth (27.7%) of the patients had clinical diagnoses of substance use disorders. In addition, in the Alcohol Use Disorders Identification Test, 43.1% had hazardous alcohol use and 38.4% were daily smokers. All substance use was more common in men than in women. Bipolar patients had the highest prevalence of alcohol use disorders and hazardous use, whereas those with schizophrenia or schizoaffective disorder were more often daily smokers. In regression analyses, self-reported alcohol consumption was associated with symptoms of anxiety and borderline personality disorder and low conscientiousness. No associations emerged for smoking. Conclusions The vast majority of psychiatric care patients have a diagnosed substance use disorder, hazardous alcohol use, or smoke daily, males more often than females. Bipolar patients have the highest rates of alcohol misuse, schizophrenia or schizoaffective disorder patients of smoking. Alcohol use may associate with symptoms of anxiety, borderline personality disorder, and low conscientiousness. Preventive and treatment efforts specifically targeted at harmful substance use among psychiatric patients are necessary. PMID- 29179662 TI - Patient experience with healthcare services among older adults with serious mental illness compared to the general older population. AB - Objective To compare patient experience with healthcare services and providers among older patients (>=50 years old) with and without serious mental illness. Methods Using secondary data from the Medical Expenditures Panel Survey from 2003 through 2013, we compared adults aged 50 years and older with schizophrenia spectrum disorder ( n = 106), mood disorders (i.e., major depressive disorder and bipolar disorder) ( n = 419), and no serious mental illness ( n = 34,921). Results Older adults with schizophrenia spectrum disorder reported significantly worse provider communication than older adults without serious mental illness. Older adults with mood disorders reported the greatest barriers to shared decision-making and the greatest difficulty accessing services. Conclusions Our results highlight the need to improve the patient experience of older adults with serious mental illness. Addressing provider communication, shared decision making, and access to care among this vulnerable group of older adults may impact clinical outcomes and costs. Future research examining the extent to which improving the patient experience may improve health outcomes and enhance treatment for this highly vulnerable older group is warranted. PMID- 29179663 TI - Balint group leadership: Conceptual foundations and a framework for leadership development? AB - This article is based on a talk given at the International Balint Federation leadership congress in Warsaw (September 2016). It explores the conceptual foundations of Balint group leadership and starts by emphasizing the mutuality between psychoanalysts and medical practitioners working together. The parallel process between consulting room and group, and subsequently from group back to the consulting room, is delineated as the central construct in understanding the role of the leader. Having proposed a conceptual model for thinking about leadership interventions, the article discusses developments in some contemporary approaches to leadership: coleadership, the use of role play, psychodrama, pushback, and morale. It concludes by introducing Keats' notion of negative capability as a way of thinking about creativity in Balint group leadership. PMID- 29179664 TI - Incorporating peer support during in vivo exposure to reverse dropout from prolonged exposure therapy for posttraumatic stress disorder: Clinical outcomes. AB - Objective Prolonged exposure is characterized by reported dropout rates ranging from 25% to 40%. This premature attrition is also observed in other evidence based treatments for posttraumatic stress disorder. While home-based telehealth delivery of prolonged exposure resolves logistical barriers to care such as travel time and cost, dropout appears unaffected. A previous study on dropouts from prolonged exposure delivered via telehealth found that Veterans, particularly those receiving care via telehealth, reported problems with in vivo exposure and that having a peer to offer support during in vivo exposure assignments might have prevented their attrition from treatment. Methods The present pilot study treatment was designed in a manner consistent with the aforementioned Veteran suggestions, specifically to involve peers offering verbal support and encouragement during in vivo exposure homework. Such a treatment modification might be particularly useful for those receiving care via telehealth, given increased difficulties with exposure reported when this treatment delivery modality is used. It was hypothesized that dropouts would agree to reengage in treatment with a peer and would subsequently evince improvement in posttraumatic stress disorder and depression scores as a result of this treatment reengagement. Results Of 82 dropouts from prolonged exposure, 29 reentered treatment when offered peer support during exposure (12 in telehealth and 17 in person). Conclusion Treatment reentry was effective insofar as indices of both posttraumatic stress disorder and depression were significantly reduced in both telehealth and in person groups, indicating that using peers in this way may be an effective means by which to return Veterans to care, and ultimately reduce symptomatology. PMID- 29179665 TI - Effect size calculation in meta-analyses of psychotherapy outcome research. AB - Meta-analysis of psychotherapy intervention research normally examines differences between treatment groups and some form of comparison group (e.g., wait list control; alternative treatment group). The effect of treatment is normally quantified as a standardized mean difference (SMD). We describe procedures for computing unbiased estimates of the population SMD from sample data (e.g., group Ms and SDs), and provide guidance about a number of complications that may arise related to effect size computation. These complications include (a) incomplete data in research reports; (b) use of baseline data in computing SMDs and estimating the population standard deviation (sigma); (c) combining effect size data from studies using different research designs; and (d) appropriate techniques for analysis of data from studies providing multiple estimates of the effect of interest (i.e., dependent effect sizes). Clinical or Methodological Significance of this article: Meta-analysis is a set of techniques for producing valid summaries of existing research. The initial computational step for meta-analyses of research on intervention outcomes involves computing an effect size quantifying the change attributable to the intervention. We discuss common issues in the computation of effect sizes and provide recommended procedures to address them. PMID- 29179666 TI - The inflammatory response to stress and angiogenesis in liver resection for colorectal liver metastases: a randomized controlled trial comparing open versus laparoscopic approach. AB - BACKGROUND: This study evaluates the surgical stress response following laparoscopic and open liver resection for colorectal liver metastasis (CRLM). METHODS: Patients with CRLM were prospectively randomized to receive open or laparoscopic liver resection (NCT03131778). Blood samples were drawn preoperatively and 24 h after resection. The serum interleukin-6 (IL-6) and IL-8 levels were measured. Furthermore, the mRNA levels of angiogenesis-related factors (vascular endothelial growth factor [VEGF] and HIF-1) and inflammation related factors (COX-2 and MMP-9) in both tumor tissue and normal liver parenchyma were detected. RESULTS: Twenty patients for each arm were included. Size of metastasis, type of resection, and neoadjuvant therapy were comparable between groups. Postoperative stay was shorter in the laparoscopic group. Higher levels of IL-6 were observed after the operation in both open and laparoscopic groups, although no differences in the post-operative levels between the groups was noted. Similarly, there were no significant differences in the mRNA expression of VEGF, HIF-1, MMP-9, and COX-2 between the treatment groups. No differences were observed in terms of overall survival and disease free survival. CONCLUSIONS: The immunological effects of treatment were similar between the groups. Thus, the laparoscopic approach does not seem to significantly influence the surgical stress and tumor related factors in patients suffering from colorectal liver metastases.

PMID- 29179667 TI - High-Fidelity Measures of Whole-Brain Functional Connectivity and White Matter Integrity Mediate Relationships between Traumatic Brain Injury and Post-Traumatic Stress Disorder Symptoms. AB - Traumatic brain injury (TBI) disrupts brain communication and increases risk for post-traumatic stress disorder (PTSD). However, mechanisms by which TBI-related disruption of brain communication confers PTSD risk have not been successfully elucidated in humans. This may be in part because functional MRI (fMRI), the most common technique for measuring functional brain communication, is unreliable for characterizing individual patients. However, this unreliability can be overcome with sufficient within-individual data. Here, we examined whether relationships could be observed among TBI, structural and functional brain connectivity, and PTSD severity by collecting ~3.5 hours of resting-state fMRI and diffusion tensor imaging (DTI) data in each of 26 United States military veterans. We observed that a TBI history was associated with decreased whole-brain resting-state functional connectivity (RSFC), while the number of lifetime TBIs was associated with reduced whole-brain fractional anisotropy (FA). Both RSFC and FA explained independent variance in PTSD severity, with RSFC mediating the TBI-PTSD relationship. Finally, we showed that large amounts of per-individual data produced highly reliable RSFC measures, and that relationships among TBI, RSFC/FA, and PTSD could not be observed with typical data quantities. These results demonstrate links among TBI, brain connectivity, and PTSD severity, and illustrate the need for precise characterization of individual patients using high-data fMRI scanning. PMID- 29179669 TI - In Situ Activation and Preservation of Penile Progenitor Cells Using Icariside II in an Obesity-Associated Erectile Dysfunction Rat Model. AB - Obesity-associated erectile dysfunction (ED) involves pathologic change that may be related to deficit of the penile endogenous stem/progenitor cells. Therefore, an in-depth study of the penile stem/progenitor cells in the pathogenesis of ED is warranted. For this study, eight Zucker Lean (ZUC-Leprfa 186; ZL group) and 16 Zucker Fatty (ZUC-Leprfa 185; ZF) male rats received an intraperitoneal injection of 5-ethynyl-2-deoxyuridine (EdU) to track endogenous stem cells. Twelve weeks later, the ZF rats were randomized to gavage feeding with 1.5 mg/kg/day of icariside II (ZF + ICA II group) or the solvent (ZF group). Treatment lasted 4 weeks and was followed by a 1-week washout period. ZF rats had impaired erectile function with related pathologic changes compared with ZL rats. ICA II treatment restored erectile function and prevented smooth muscle atrophy, endothelial dysfunction, and lipid accumulation compared with no treatment. EdU label retaining cell levels were higher in the ZF + ICA II group compared with the ZF group. Histone 3 phosphorylation at Ser 10, a specific mitotic cell marker, was additionally used to identify dividing cells. ICA II activated more penile stem cells to proliferate in ZF rats compared with ZL rats. These results suggest that ZF rats can be used as a model for obesity-associated ED and that ICA II improves erectile function and pathologic changes through endogenous progenitor cell preservation and proliferation. PMID- 29179670 TI - Detecting transitions in protein dynamics using a recurrence quantification analysis based bootstrap method. AB - BACKGROUND: Proteins undergo conformational transitions over different time scales. These transitions are closely intertwined with the protein's function. Numerous standard techniques such as principal component analysis are used to detect these transitions in molecular dynamics simulations. In this work, we add a new method that has the ability to detect transitions in dynamics based on the recurrences in the dynamical system. It combines bootstrapping and recurrence quantification analysis. We start from the assumption that a protein has a "baseline" recurrence structure over a given period of time. Any statistically significant deviation from this recurrence structure, as inferred from complexity measures provided by recurrence quantification analysis, is considered a transition in the dynamics of the protein. RESULTS: We apply this technique to a 132 ns long molecular dynamics simulation of the beta-Lactamase Inhibitory Protein BLIP. We are able to detect conformational transitions in the nanosecond range in the recurrence dynamics of the BLIP protein during the simulation. The results compare favorably to those extracted using the principal component analysis technique. CONCLUSIONS: The recurrence quantification analysis based bootstrap technique is able to detect transitions between different dynamics states for a protein over different time scales. It is not limited to linear dynamics regimes, and can be generalized to any time scale. It also has the potential to be used to cluster frames in molecular dynamics trajectories according to the nature of their recurrence dynamics. One shortcoming for this method is the need to have large enough time windows to insure good statistical quality for the recurrence complexity measures needed to detect the transitions. PMID- 29179671 TI - Phylogenomics of Cas4 family nucleases. AB - BACKGROUND: The Cas4 family endonuclease is a component of the adaptation module in many variants of CRISPR-Cas adaptive immunity systems. Unlike most of the other Cas proteins, Cas4 is often encoded outside CRISPR-cas loci (solo-Cas4) and is also found in mobile genetic elements (MGE-Cas4). RESULTS: As part of our ongoing investigation of CRISPR-Cas evolution, we explored the phylogenomics of the Cas4 family. About 90% of the archaeal genomes encode Cas4 compared to only about 20% of the bacterial genomes. Many archaea encode both the CRISPR associated form (CAS-Cas4) and solo-Cas4, whereas in bacteria, this combination is extremely rare. The solo-cas4 genes are over-represented in environmental bacteria and archaea with small genomes that typically lack CRISPR-Cas, suggesting that Cas4 could perform uncharacterized defense or repair functions in these microbes. Phylogenomic analysis indicates that both the CRISPR-associated cas4 genes are often transferred horizontally but almost exclusively, as part of the adaptation module. The evolutionary integrity of the adaptation module sharply contrasts the rampant shuffling of CRISPR-cas modules whereby a given variant of the adaptation module can combine with virtually any effector module. The solo-cas4 genes evolve primarily via vertical inheritance and are subject only to occasional horizontal transfer. The selection pressure on cas4 genes does not substantially differ between CAS-Cas4 and solo-cas4, and is close to the genomic median. Thus, cas4 genes, similarly to cas1 and cas2, evolve similarly to 'regular' microbial genes involved in various cellular functions, showing no evidence of direct involvement in virus-host arms races. A notable feature of the Cas4 family evolution is the frequent recruitment of cas4 genes by various mobile genetic elements (MGE), particularly, archaeal viruses. The functions of Cas4 in these elements are unknown and potentially might involve anti-defense roles. CONCLUSIONS: Unlike most of the other Cas proteins, Cas4 family members are as often encoded by stand-alone genes as they are incorporated in CRISPR-Cas systems. In addition, cas4 genes were repeatedly recruited by MGE, perhaps, for anti-defense functions. Experimental characterization of the solo and MGE-encoded Cas4 nucleases is expected to reveal currently uncharacterized defense and anti defense systems and their interactions with CRISPR-Cas systems. PMID- 29179672 TI - An efficient error correction algorithm using FM-index. AB - BACKGROUND: High-throughput sequencing offers higher throughput and lower cost for sequencing a genome. However, sequencing errors, including mismatches and indels, may be produced during sequencing. Because, errors may reduce the accuracy of subsequent de novo assembly, error correction is necessary prior to assembly. However, existing correction methods still face trade-offs among correction power, accuracy, and speed. RESULTS: We develop a novel overlap-based error correction algorithm using FM-index (called FMOE). FMOE first identifies overlapping reads by aligning a query read simultaneously against multiple reads compressed by FM-index. Subsequently, sequencing errors are corrected by k-mer voting from overlapping reads only. The experimental results indicate that FMOE has highest correction power with comparable accuracy and speed. Our algorithm performs better in long-read than short-read datasets when compared with others. The assembly results indicated different algorithms has its own strength and weakness, whereas FMOE is good for long or good-quality reads. CONCLUSIONS: FMOE is freely available at https://github.com/ythuang0522/FMOC . PMID- 29179673 TI - Quantitative trait locus mapping of Populus bark features and stem diameter. AB - BACKGROUND: Bark plays important roles in photosynthate transport and storage, along with physical and chemical protection. Bark texture varies extensively among species, from smooth to fissured to deeply furrowed, but its genetic control is unknown. This study sought to determine the main genomic regions associated with natural variation in bark features and stem diameter. Quantitative trait loci (QTL) were mapped using an interspecific pseudo-backcross pedigree (Populus trichocarpa x P. deltoides and P. deltoides) for bark texture, bark thickness and diameter collected across three years, two sites and three biological replicates per site. RESULTS: QTL specific to bark texture were highly reproducible in shared intervals across sites, years and replicates. Significant positive correlations and co-localization between trait QTL suggest pleiotropic regulators or closely linked genes. A list of candidate genes with related putative function, location close to QTL maxima and with the highest expression level in the phloem, xylem and cambium was identified. CONCLUSION: Candidate genes for bark texture included an ortholog of Arabidopsis ANAC104 (PopNAC128), which plays a role in lignified fiber cell and ray development, as well as Pinin and Fasciclin (PopFLA) genes with a role in cell adhesion, cell shape and migration. The results presented in this study provide a basis for future genomic characterization of genes found within the QTL for bark texture, bark thickness and diameter in order to better understand stem and bark development in Populus and other woody perennial plants. The QTL mapping approach identified a list of prime candidate genes for further validation using functional genomics or forward genetics approaches. PMID- 29179674 TI - Value of soluble Urokinase plasminogen activator receptor over age as a biomarker of impaired myocardial relaxation. AB - BACKGROUND: SuPAR is a biomarker that reflects the level of immune activation. As inflammation plays an important role in the ageing process of the cardiovascular system, we hypothesized that suPAR might be a useful predictive biomarker of the ageing heart. METHODS: We performed conventional and tissue Doppler echocardiography and measured plasma suPAR levels. RESULTS: We studied community adults (n=120, 37.5% female) (mean age: 70.3+/-9.3 years) without known cardiovascular disease (CVD). Participants with impaired myocardial relaxation were older (84% vs 59% were aged >=71 years, p=0.002), with more diabetes mellitus (27% vs 11%, p=0.034). SuPAR levels were higher among participants with impaired myocardial relaxation (3.9 ng/ml vs 3.0 ng/ml, p=0.015). At the univariate level, older age (OR 3.6; 95%CI 1.6, 8.5; p=0.003), diabetes mellitus (OR 3.04; 95%CI 1.1, 8.8; p=0.04), systolic blood pressure (OR 1.03; 95%CI 1.001, 1.1; p=0.041) and suPAR levels >=3.00ng/ml (OR 3.4; 95%CI 1.16, 7.4; p=0.002) were associated with impaired myocardial relaxation. In multivariable regression analysis, only older age (OR 2.8; 95%CI 1.1, 6.7; p=0.026) and suPAR (OR 2.7; 95%CI 1.2, 6.1; p=0.018) remained independently associated with impaired myocardial relaxation. Receiver operating characteristics (ROC) curve analysis revealed an area under the curve (AUC) value of 0.63 (95% CI 0.54, 0.71) for model that included age alone. Addition of suPAR significantly increased AUC value to 0.70 (95%CI 0.60, 0.79), which was significantly larger than the model with age alone (p=0.016). CONCLUSION: We demonstrate additional ability of suPAR, over age, to predict impaired myocardial relaxation. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02791139 (Registered May 31, 2016). PMID- 29179676 TI - HLA genotyping by next-generation sequencing of complementary DNA. AB - BACKGROUND: Genotyping of the human leucocyte antigen (HLA) is indispensable for various medical treatments. However, unambiguous genotyping is technically challenging due to high polymorphism of the corresponding genomic region. Next generation sequencing is changing the landscape of genotyping. In addition to high throughput of data, its additional advantage is that DNA templates are derived from single molecules, which is a strong merit for the phasing problem. Although most currently developed technologies use genomic DNA, use of cDNA could enable genotyping with reduced costs in data production and analysis. We thus developed an HLA genotyping system based on next-generation sequencing of cDNA. METHODS: Each HLA gene was divided into 3 or 4 target regions subjected to PCR amplification and subsequent sequencing with Ion Torrent PGM. The sequence data were then subjected to an automated analysis. The principle of the analysis was to construct candidate sequences generated from all possible combinations of variable bases and arrange them in decreasing order of the number of reads. Upon collecting candidate sequences from all target regions, 2 haplotypes were usually assigned. Cases not assigned 2 haplotypes were forwarded to 4 additional processes: selection of candidate sequences applying more stringent criteria, removal of artificial haplotypes, selection of candidate sequences with a relaxed threshold for sequence matching, and countermeasure for incomplete sequences in the HLA database. RESULTS: The genotyping system was evaluated using 30 samples; the overall accuracy was 97.0% at the field 3 level and 98.3% at the G group level. With one sample, genotyping of DPB1 was not completed due to short read size. We then developed a method for complete sequencing of individual molecules of the DPB1 gene, using the molecular barcode technology. CONCLUSION: The performance of the automatic genotyping system was comparable to that of systems developed in previous studies. Thus, next-generation sequencing of cDNA is a viable option for HLA genotyping. PMID- 29179675 TI - Cgl2 plays an essential role in cuticular wax biosynthesis in cabbage (Brassica oleracea L. var. capitata). AB - BACKGROUND: The aerial parts of most land plants are covered with cuticular wax which is important for plants to avoid harmful factors. There is still no cloning study about wax synthesis gene of the alcohol-forming pathway in Brassica species. RESULTS: Scanning electron microscopy (SEM) showed that, compared with wild type (WT), wax crystal are severely reduced in both the adaxial and abaxial sides of cabbage (Brassica oleracea L. var. capitata L.) leaves from the LD10GL mutant. Genetic analysis results revealed that the glossy trait of LD10GL is controlled by a single recessive gene, and fine mapping results revealed that the target gene Cgl2 (Cabbage glossy 2) is located within a physical region of 170 kb on chromosome 1. Based on sequence analysis of the genes in the mapped region, the gene designated Bol013612 was speculated to be the candidate gene. Gene Bol013612 is homologous to Arabidopsis CER4, which encodes fatty acyl-coenzyme A reductase. Sequencing identified a single nucleotide substitution at an intron/exon boundary that results in an insertion of six nucleotides in the cDNA of Bol013612 in LD10GL. The phenotypic defect of LD10GL was confirmed by a functional complementation test with Arabidopsis mutant cer4. CONCLUSIONS: Our results indicated that wax crystals of cabbage mutant LD10GL are severely reduced and mutation of gene Bol013612 causes a glossy phenotype in the LD10GL mutant. PMID- 29179677 TI - Robust transcriptional signatures for low-input RNA samples based on relative expression orderings. AB - BACKGROUND: It is often difficult to obtain sufficient quantity of RNA molecules for gene expression profiling under many practical situations. Amplification from low-input samples may induce artificial signals. RESULTS: We compared the expression measurements of low-input mRNA samples, from 25 pg to 1000 pg mRNA, which were amplified and profiled by Smart-seq, DP-seq and CEL-seq techniques using the Illumina HiSeq 2000 platform, with those of the paired high-input (50 ng) mRNA samples. Even with 1000 pg mRNA input, we found that thousands of genes had at least 2 folds-change of expression levels in the low-input samples compared with the corresponding paired high-input samples. Consequently, a transcriptional signature based on quantitative expression values and determined from high-input RNA samples cannot be applied to low-input samples, and vice versa. In contrast, the within-sample relative expression orderings (REOs) of approximately 90% of all the gene pairs in the high-input samples were maintained in the paired low-input samples with 1000 pg input mRNA molecules. Similar results were observed in the low-input total RNA samples amplified and profiled by the Whole-Genome DASL technique using the Illumina HumanRef-8 v3.0 platform. As a proof of principle, we developed REOs-based signatures from high-input RNA samples for discriminating cancer tissues and showed that they can be robustly applied to low-input RNA samples. CONCLUSIONS: REOs-based signatures determined from the high-input RNA samples can be robustly applied to samples profiled with the low-input RNA samples, as low as the 1000 pg and 250 pg input samples but no longer stable in samples with less than 250 pg RNA input to a certain degree. PMID- 29179678 TI - A prediction model for the grade of liver fibrosis using magnetic resonance elastography. AB - BACKGROUND: Liver stiffness measurement (LSM) has recently become available for assessment of liver fibrosis. We aimed to develop a prediction model for liver fibrosis using clinical variables, including LSM. METHODS: We performed a prospective study to compare liver fibrosis grade with fibrosis score. LSM was measured using magnetic resonance elastography in 184 patients that underwent liver resection, and liver fibrosis grade was diagnosed histologically after surgery. Using the prediction model established in the training group, we validated the classification accuracy in the independent test group. RESULTS: First, we determined a cut-off value for stratifying fibrosis grade using LSM in 122 patients in the training group, and correctly diagnosed fibrosis grades of 62 patients in the test group with a total accuracy of 69.3%. Next, on least absolute shrinkage and selection operator analysis in the training group, LSM (r = 0.687, P < 0.001), indocyanine green clearance rate at 15 min (ICGR15) (r = 0.527, P < 0.001), platelet count (r = -0.537, P < 0.001) were selected as variables for the liver fibrosis prediction model. This prediction model applied to the test group correctly diagnosed 32 of 36 (88.8%) Grade I (F0 and F1) patients, 13 of 18 (72.2%) Grade II (F2 and F3) patients, and 7 of 8 (87.5%) Grade III (F4) patients in the test group, with a total accuracy of 83.8%. CONCLUSIONS: The prediction model based on LSM, ICGR15, and platelet count can accurately and reproducibly predict liver fibrosis grade. PMID- 29179679 TI - Attenuating the rate of total body fat accumulation and alleviating liver damage by oral administration of vitamin D-enriched edible mushrooms in a diet-induced obesity murine model is mediated by an anti-inflammatory paradigm shift. AB - BACKGROUND: Hypovitaminosis D is associated with many features of the metabolic syndrome, including non-alcoholic fatty liver disease. Vitamin D-enriched mushrooms extracts exert a synergistic anti-inflammatory effect. The aim of the present study is to determine the immunomodulatory effect of oral administration of vitamin D-enriched mushrooms extracts on high-fat diet (HFD) animal model of non-alcoholic steatohepatitis (NASH). METHODS: C57BL/6 mice on HFD were orally administered with vitamin D supplement, Lentinula edodes (LE) mushrooms extract, or vitamin D-enriched mushrooms extract for 25 weeks. Mice were studied for the effect of the treatment on the immune system, liver functions and histology, insulin resistance and lipid profile. RESULTS: Treatment with vitamin D-enriched LE extracts was associated with significant attenuation of the rate of total body fat accumulation, along with a decrease in hepatic fat content as measured by an EchoMRI. Significant alleviation of liver damage manifested by a marked decrease in ALT, and AST serum levels (from 900 and 1021 U/L in the control group to 313 and 340; 294 and 292; and 366 and 321 U/L for ALT and AST, in Vit D, LE and LE + Vit D treated groups, respectively). A corresponding effect on hepatocyte ballooning were also noted. A significant decrease in serum triglycerides (from 103 to 75, 69 and 72 mg/dL), total cholesterol (from 267 to 160, 157 and 184 mg/dL), and LDL cholesterol (from 193 mg/dL to 133, 115 and 124 mg/dL) along with an increase in the HDL/LDL ratio, and improved glucose levels were documented. These beneficial effects were associated with a systemic immunomodulatory effect associated with an increased CD4/CD8 lymphocyte ratio (from 1.38 in the control group to 1.69, 1.71 and 1.63), and a pro- to an anti-inflammatory cytokine shift. CONCLUSIONS: Oral administration of vitamin-D enriched mushrooms extracts exerts an immune modulatory hepato-protective effect in NASH model. PMID- 29179680 TI - Stercoral colitis complicated with ischemic colitis: a double-edge sword. AB - BACKGROUND: Stercoral colitis is a rare inflammatory process involving the colonic wall secondary to fecal impaction with high morbidity and mortality; especially if complicated with ischemic colitis, stercoral ulcer formation and subsequent perforation. There are several case reports published on abdominal perforation resulting from stercoral colitis. However, stercoral colitis complicated by ischemic colitis is rare. The purpose of this case report is to describe the potential challenges in the diagnosis and management of stercoral colitis with ischemic colitis. CASE PRESENTATION: An 87 years old male with history of chronic constipation presents with severe abdominal pain to the emergency department. The patient was hemodynamically stable. On physical examination, the abdomen was mildly distended with moderate tenderness. Lab work was significant for leukocytosis and lactic acidosis. Abdominal CT scan revealed large amount of retained stool in the colon, bowel wall thickening and infiltration of peri-colonic fat, which were suggestive for stercoral colitis. Patient was started on IV fluids and antibiotics. He was given an enema, followed by laxative and manual disimpaction of stool. Colonoscopy was performed and biopsies were obtained. Tissue biopsy was significant for focal active colitis with regenerative glandular changes and neural hyperplasia. CONCLUSION: Elevated lactic acid level secondary to ischemia of the bowel wall with CT scan findings aid in establishing the diagnosis of stercoral colitis complicated with ischemic colitis. Urgent treatment with laxatives and fecal disimpaction is indicated to prevent perforation and peritonitis. PMID- 29179681 TI - Low flow extracorporeal CO2 removal in ARDS patients: a prospective short-term crossover pilot study. AB - BACKGROUND: Lung protective mechanical ventilation (MV) is the corner stone of therapy for ARDS. However, its use may be limited by respiratory acidosis. This study explored feasibility of, effectiveness and safety of low flow extracorporeal CO2 removal (ECCO2R). METHODS: This was a prospective pilot study, using the Abylcap(r) (Bellco) ECCO2R, with crossover off-on-off design (2-h blocks) under stable MV settings, and follow up till end of ECCO2R. Primary endpoint for effectiveness was a 20% reduction of PaCO2 after the first 2-h. Adverse events (AE) were recorded prospectively. We included 10 ARDS patients on MV, with PaO2/FiO2 < 150 mmHg, tidal volume <= 8 mL/kg with positive end expiratory pressure >= 5 cmH2O, FiO2 titrated to SaO2 88-95%, plateau pressure >= 28 cmH2O, and respiratory acidosis (pH <7.25). RESULTS: After 2-h of ECCO2R, 6 patients had a >= 20% decrease in PaCO2 (60%); PaCO2 decreased 28.4% (from 58.4 to 48.7 mmHg, p = 0.005), and pH increased (1.59%, p = 0.005). ECCO2R was hemodynamically well tolerated. During the whole period of ECCO2R, 6 patients had an AE (60%); bleeding occurred in 5 patients (50%) and circuit thrombosis in 3 patients (30%), these were judged not to be life threatening. CONCLUSIONS: In ARDS patients, low flow ECCO2R significantly reduced PaCO2 after 2 h, Follow up during the entire ECCO2R period revealed a high incidence of bleeding and circuit thrombosis.

PMID- 29179682 TI - Faecal bacterial microbiota in patients with cirrhosis and the effect of lactulose administration. AB - BACKGROUND: Gut microbiota may be altered in patients with cirrhosis, and may further change after administration of lactulose. We studied the composition of gut microbiota in patients with cirrhosis and assessed the effect on it of lactulose administration. METHODS: Stool specimens were collected from 35 patients with cirrhosis (male 26; median [range] age: 42 [29-65] years) and 18 healthy controls (male 14; 44.5 [24-67] years); 21 patients provided another specimen after lactulose administration for 55 [42-77] days. For each, a DNA library of V3 region of bacterial 16S ribosomal RNA was subjected to paired-end Illumina sequencing. Inter-specimen relationship was studied using principal co ordinate analysis. Abundances of various bacterial taxa, and indices of alpha and beta diversity were compared, between patients and controls, and between specimens collected before and after lactulose. RESULTS: Gut microbiota from cirrhosis patients and controls showed differential clustering, and microbiota from patients with cirrhosis had less marked alpha diversity. Abundances of dominant phyla (Bacteroidetes, Firmicutes and Proteobacteria) were similar. However, patients with cirrhosis had lower abundances of five phyla, namely Tenericutes, Cyanobacteria, Spirochaetes, Elusimicrobia and Lentisphaerae, and differences in abundances of several families and genera than in controls. Lactulose administration did not lead to any change in alpha and beta diversities, species richness and abundances of various bacterial taxa in gut microbiota. CONCLUSIONS: Gut microbiota in cirrhosis differ from healthy persons and do not change following lactulose administration. The latter suggests that the effect of lactulose on hepatic encephalopathy may not be related to alteration in gut microbiota.

PMID- 29179684 TI - Potential applications of a new short food frequency questionnaire for CKD patients. AB - Diet is among the most modifiable risk factors for chronic kidney disease (CKD) progression. Studies of beneficial dietary patterns for persons with CKD have largely utilized dietary assessment measures developed in individuals without CKD. In BMC Nephrology, Affret et al. report on their study of the reproducibility of a newly developed short 49-item food frequency questionnaire (SFFQ) adapted to patients with CKD. Here, we discuss potential applications of this SFFQ, towards better understanding of which dietary patterns portend the most favorable outcomes in CKD. PMID- 29179685 TI - Frequency of data extraction errors and methods to increase data extraction quality: a methodological review. AB - BACKGROUND: Our objective was to assess the frequency of data extraction errors and its potential impact on results in systematic reviews. Furthermore, we evaluated the effect of different extraction methods, reviewer characteristics and reviewer training on error rates and results. METHODS: We performed a systematic review of methodological literature in PubMed, Cochrane methodological registry, and by manual searches (12/2016). Studies were selected by two reviewers independently. Data were extracted in standardized tables by one reviewer and verified by a second. RESULTS: The analysis included six studies; four studies on extraction error frequency, one study comparing different reviewer extraction methods and two studies comparing different reviewer characteristics. We did not find a study on reviewer training. There was a high rate of extraction errors (up to 50%). Errors often had an influence on effect estimates. Different data extraction methods and reviewer characteristics had moderate effect on extraction error rates and effect estimates. CONCLUSION: The evidence base for established standards of data extraction seems weak despite the high prevalence of extraction errors. More comparative studies are needed to get deeper insights into the influence of different extraction methods. PMID- 29179686 TI - Piloting electronic screening forms in primary care: findings from a mixed methods study to identify patients eligible for low dose CT lung cancer screening. AB - BACKGROUND: Recent evidence suggests that screening with low dose computed tomography (LDCT) scans significantly reduces mortality from lung cancer. However, optimal methods to identify potentially eligible patients in primary care are not known. Using brief electronic screening forms administered prior to a primary care visit is a strategy to identify high risk, asymptomatic patients eligible for LDCT screening. The objective of this study was to compare the acceptability and feasibility of using brief electronic versus paper screening forms to identify eligible patients at high risk of developing lung cancer in primary care. METHODS: A mixed method pilot comparative study was conducted in primary care. Practices were allocated to an electronic form (e-form) group or a paper-based form (p-form) group. Allocation was randomly assigned for the first practice then by alternation. Patients in the e-form practices completed forms at home via the web or in the waiting room on a tablet. Patients in p-form practices completed forms in waiting rooms. Interviews were conducted with patients, administrators, and primary care physicians (PCPs) about their experiences. RESULTS: Six of 30 (20%) eligible practices agreed to participate. Over the 16 week study period, a total of 831 of an expected 1442 patients (58%) aged 55-74 years were enrolled; 573/690 (83%) patients in the e-form group and 258/752 (34%) in the p-form group. Of the 573 participants in the e-form group, 335 (58%) completed forms via the web; 238 (29%) did so via tablet. Twenty-four interviews were conducted with 15 patients, 5 administrative staff and 4 PCPs. Patients were willing to discuss lung cancer screening eligibility with their PCP. Staff members expressed low administrative burden except for an extra step to link appointment information to patient demographics to identify eligible patients. PCPs indicated that forms were reminders to discuss smoking cessation. PCPs in the e-form group reported that patients asked questions about screening. CONCLUSION: There was fairly low uptake by primary care practices. For e-forms to be feasible in practice workflow, electronic medical record software needs to link appointment information with patient eligibility requirements. The use of brief pre-consultation electronic screening forms for LDCT eligibility encouraged PCPs to discuss smoking cessation with patients. PMID- 29179687 TI - Faecal microbiota transplantation: a regulatory hurdle? AB - During faecal microbiota transplantation, stool from a healthy donor is transplanted to treat a variety of dysbiosis-associated gut diseases. Competent authorities are faced with the challenge to provide adequate regulation. Currently, regulatory harmonization is completely lacking and authorities apply non-existing to most stringent requirements. A regulatory approach for faecal microbiota transplantation could be inserting faecal microbiota transplantation in the gene-, cell- and tissue regulations, including the hospital exemption system in the European Advanced Therapy Medicinal Products regulation, providing a pragmatic and efficacy-risk balanced approach and granting all patients as a matter of principle access to this therapy. PMID- 29179688 TI - Evaluating genetic ancestry and self-reported ethnicity in the context of carrier screening. AB - BACKGROUND: Current professional society guidelines recommend genetic carrier screening be offered on the basis of ethnicity, or when using expanded carrier screening panels, they recommend to compute residual risk based on ethnicity. We investigated the reliability of self-reported ethnicity in 9138 subjects referred to carrier screening. Self-reported ethnicity gathered from test requisition forms and during post-test genetic counseling, and genetic ancestry predicted by a statistical model, were compared for concordance. RESULTS: We identified several discrepancies between the two sources of self-reported ethnicity and genetic ancestry. Only 30.3% of individuals who indicated Mediterranean ancestry during consultation self-reported this on requisition forms. Additionally, the proportion of individuals who reported Southeast Asian but were estimated to have a different genetic ancestry was found to depend on the source of self-report. Finally, individuals who reported Latin American demonstrated a high degree of ancestral admixture. As a result, carrier rates and residual risks provided for patient decision-making are impacted if using self-reported ethnicity. CONCLUSION: Our analysis highlights the unreliability of ethnicity classification based on patient self-reports. We recommend the routine use of pan-ethnic carrier screening panels in reproductive medicine. Furthermore, the use of an ancestry model would allow better estimation of carrier rates and residual risks. PMID- 29179689 TI - The optimum sevoflurane concentration for supraglottic airway device BlockbusterTM insertion with spontaneous breathing in obese patients: a prospective observational study. AB - BACKGROUND: Airway management of the obese patient presenting for surgery is more likely to be a challenging problem. Supraglottic airway device has been adopted as a bridge to connect ventilation and tracheal intubation in obese patients who would be suffered with difficult intubation. The optimum sevoflurane concentration for supraglottic airway device insertion allowing spontaneous breathing in 50% of obese patients (ED50) is not known. The purpose of this study was to determine the ED50 of sevoflurane for supraglottic airway device BlockbusterTM insertion with spontaneous breathing in obese patients requiring general anesthesia. METHODS: Thirty elective obese patients (body mass index 30 50 kg/m2) undergoing bariatric surgery were recruited in this study. The predetermined target sevoflurane concentration (initiating at 2.5% with 0.5% as a step size) was sustained for >5 min using a modified Dixon's up-and-down method, and then the supraglottic airway device BlockbusterTM was inserted. The patient's response to supraglottic airway device insertion was classified as either 'movement' or 'no-movement'. The ED50 of sevoflurane were determined by calculating the midpoint concentration of crossover point from 'movement' or 'no movement' response. RESULTS: The ED50 of sevoflurane for supraglottic airway device BlockbusterTM insertion in obese patients calculated using up-and-down method were 2.50 +/- 0.60%. The ED50 and ED95 (95% confidence interval) obtained by probit regression analysis were 2.35 (1.28-3.42) % and 4.03 (3.16-17.83) % for supraglottic airway device BlockbusterTM insertion, respectively. CONCLUSION: We conclude that the optimum end-tidal sevoflurane concentration required for the supraglottic airway device BlockbusterTM insertion allowing spontaneous breathing in 50% of obese patients (ED50) is 2.5 +/- 0.6%.

PMID- 29179690 TI - Unique proximal tubular cell injury and the development of acute kidney injury in adult patients with minimal change nephrotic syndrome. AB - BACKGROUND: Adult patients with minimal change nephrotic syndrome (MCNS) are often associated with acute kidney injury (AKI). To assess the mechanisms of AKI, we examined whether tubular cell injuries unique to MCNS patients exist. METHODS: We performed a retrospective analysis of clinical data and tubular cell changes using the immunohistochemical expression of vimentin as a marker of tubular injury and dedifferentiation at kidney biopsy in 37 adult MCNS patients. AKI was defined by the criteria of the Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guidelines for AKI. RESULTS: Thirteen patients (35.1%) were designated with AKI at kidney biopsy. No significant differences in age, history of hypertension, chronic kidney disease, diuretics use, proteinuria, and serum albumin were noted between the AKI and non-AKI groups. Urinary N-acetyl-beta-D glucosaminidase (uNAG) and urinary alpha1-microglobulin (uA1MG) as markers of tubular injury were increased in both groups, but the levels were significantly increased in the AKI group compared with the non-AKI group. The incidence of vimentin-positive tubules was comparable between AKI (84.6%) and non-AKI (58.3%) groups, but vimentin-positive tubular area per interstitial area was significantly increased in the AKI group (19.8%) compared with the non-AKI group (6.8%) (p = 0.011). Vimentin-positive injured tubules with tubular simplification (loss of brush-border of the proximal tubule/dilated tubule with flattening of tubular epithelium) were observed in the vicinity of glomeruli in both groups, suggesting that the proximal convoluted tubules were specifically injured. Two patients exhibited relatively severe tubular injuries with vimentin positivity and required dialysis within 2 weeks after kidney biopsy. The percentage of the vimentin-positive tubular area was positively correlated with uNAG but not with uA1MG in the non-AKI group. CONCLUSIONS: Proximal tubular injuries with increased uNAG exist in MCNS patients without renal dysfunction and were more severe in the AKI group than they were in the non-AKI group. The unique tubular injuries probably due to massive proteinuria might be a predisposing factor for the development of severe AKI in adult MCNS patients. PMID- 29179691 TI - Comparison of sedation between the endoscopy room and operation room during endoscopic submucosal dissection for neoplasms in the upper gastrointestinal tract. AB - BACKGROUND: The present study was performed to compare the safety of sedation during endoscopic submucosal dissection (ESD) in the endoscopy room versus operation room. METHODS: In total, 297 patients with gastrointestinal tumors who underwent ESD from January 2011 to December 2016 were retrospectively reviewed. The patients were divided into two groups: those who underwent ESD in the endoscopy room without propofol (Group E) versus operation room with propofol (Group O). The patient, tumor, and procedure characteristics; adverse events; and treatment outcomes were compared between the two groups. RESULTS: The patient and tumor characteristics, including age (73.6 +/- 8.2 vs. 72.5 +/- 9.1 years), comorbidities, and tumor size and histology, were not different between Groups E and O. The ESD procedure time was comparable between Groups E and O (105.4 +/- 70.4 vs. 106.5 +/- 64.4 min), and the anesthesia time was equivalent (138.3 +/- 78.1 vs. 148.4 +/- 68.8 min). There were no significant differences in adverse events between the two groups. During the ESD procedure, desaturation occurred significantly more often in Group E than O (12.9% vs. 4.0%, P = 0.021, odds ratio: 3.53, 95% CI: 1.17-14.4). The recovery time after ESD was significantly longer in Group E than O (180 (100-360) vs. 90 (0-180) min, P < 0.001). CONCLUSIONS: A decreased desaturation rate and shorter recovery time after ESD were the advantages of sedation in the operation room with propofol compared with sedation in the endoscopy room. These findings warrant further exploration of the advantages of safe and effective ESD for upper gastrointestinal neoplasms in the operation room. PMID- 29179692 TI - Dietary habits and obesity indices in patients with gastro-esophageal reflux disease: a comparative cross-sectional study. AB - BACKGROUND: Gastro-esophageal reflux disease (GERD) is suggested to be associated with some socio-demographic and lifestyle factors. Although the roles of some factors such as obesity are well documented, evidence on the impact of other factors such as dietary habits are still inconclusive. The aim of this study was to determine the relationship between socio-demographic and lifestyle factors with GERD in participants referred to a teaching hospital in Zahedan, South-East of Iran. METHODS: This comparative cross-sectional study was conducted during 2014-2015. All patients completed a structured questionnaire regarding information on socio-demographic status, lifestyle factors and dietary habits. Anthropometric indices including body mass index (BMI) and waist circumference (WC) were used to determine general and central obesity, respectively. Data were analyzed using SPSS software version 22. Value of p < 0.05 was considered as statistically significant. RESULTS: Five hundred and five participants, including 285 GERD and 220 Non-GERD participants participated in the study. In univariate analysis, being married (OR = 1.57, 95%CI = 1.04, 2.36), general obesity (OR = 1.77, 95%CI = 1.11, 2.81), central obesity (OR = 2.09, 95%CI = 1.46,3.01) and consumption of citrus fruits between meals (OR = 1.69, 95%CI = 1.04, 2.73) were associated with higher odds of GERD, while higher educational level (OR = 0.53, 95%CI = 0.36,0.77) and regular physical activity >=2 h/week (OR = 0.53, 95%CI = 0.30, 0.94) were associated with lower odds of GERD. In the adjusted model, central obesity (OR = 1.88, 95%CI = 1.18, 3.01) and consumption of citrus fruits between meals (OR = 2.22, 95%CI = 1.30, 3.81) were positively associated with odds of GERD, while higher educational level (OR = 0.55, 95%CI = 0.33, 0.91) was associated with decreased odds of GERD. CONCLUSION: According to the results of the current study, central obesity as determined by WC and citrus fruit intake were independent factors associated with GERD. Therefore, lifestyle modification might have a positive effect in the treatment of GERD in an urban population of Iran.

PMID- 29179693 TI - Unloading shoes for intermittent claudication: a randomised crossover trial. AB - BACKGROUND: The purpose of this study was to assess the functional effects and acceptability of rocker-soled shoes that were designed to relatively "unload" the calf muscles during walking in people with calf claudication due to peripheral arterial disease. METHODS: In this randomised AB/BA crossover trial, participants completed two assessment visits up to two weeks apart. At each visit, participants completed walking tests whilst wearing the unloading shoes or visually-similar control shoes. At the end of the second visit, participants were given either the unloading or control shoes to use in their home environment for 2 weeks, with the instruction to wear them for at least 4 h every day. The primary outcome was 6-min walk distance. We also assessed pain-free walking distance and gait biomechanical variables during usual-pace walking, adverse events, and participants' opinions about the shoes. Data for continuous outcomes are presented as mean difference between conditions with corresponding 95% confidence interval. RESULTS: Thirty-four participants (27 males, mean age 68 years, mean ankle-brachial index 0.54) completed both assessment visits. On average, the 6-min walk distance was 11 m greater when participants wore the control shoes (95% CI -5 to 26), whereas mean pain-free walking distance was 7 m greater in the unloading shoes (95% CI -17 to 32). Neither of these differences were statistically significant (p = 0.18 and p = 0.55, respectively). This was despite the unloading shoes reducing peak ankle plantarflexion moment (mean difference 0.2 Nm/kg, 95% CI 0.0 to 0.3) and peak ankle power generation (mean difference 0.6 W/kg, 95% CI 0.2 to 1.0) during pain-free walking. The survey and interview data was mixed, with no clear differences between the unloading and control shoes. CONCLUSIONS: Shoes with modified soles to relatively unload the calf muscles during walking conferred no substantial acute functional benefit over control shoes.

PMID- 29179695 TI - Nonlocal total variation based on symmetric Kullback-Leibler divergence for the ultrasound image despeckling. AB - BACKGROUND: Ultrasound imaging is safer than other imaging modalities, because it is noninvasive and nonradiative. Speckle noise degrades the quality of ultrasound images and has negative effects on visual perception and diagnostic operations. METHODS: In this paper, a nonlocal total variation (NLTV) method for ultrasonic speckle reduction is proposed. A spatiogram similarity measurement is introduced for the similarity calculation between image patches. It is based on symmetric Kullback-Leibler (KL) divergence and signal-dependent speckle model for log compressed ultrasound images. Each patch is regarded as a spatiogram, and the spatial distribution of each bin of the spatiogram is regarded as a weighted Gamma distribution. The similarity between the corresponding bins of the two spatiograms is computed by the symmetric KL divergence. The Split-Bregman fast algorithm is then used to solve the adapted NLTV object function. Kolmogorov Smirnov (KS) test is performed on synthetic noisy images and real ultrasound images. RESULTS: We validate our method on synthetic noisy images and clinical ultrasound images. Three measures are adopted for the quantitative evaluation of the despeckling performance: the signal-to-noise ratio (SNR), structural similarity index (SSIM), and natural image quality evaluator (NIQE). For synthetic noisy images, when the noise level increases, the proposed algorithm achieves slightly higher SNRS than that of the other two algorithms, and the SSIMS yielded by the proposed algorithm is obviously higher than that of the other two algorithms. For liver, IVUS and 3DUS images, the NIQE values are 8.25, 6.42 and 9.01, all of which are higher than that of the other two algorithms. CONCLUSIONS: The results of the experiments over synthetic and real ultrasound images demonstrate that the proposed method outperforms current state-of-the-art despeckling methods with respect to speckle reduction and tissue texture preservation. PMID- 29179696 TI - Secondary sclerosing cholangitis in localized hepatobiliary tuberculosis simulating cholangiocarcinoma: a rare case report. AB - BACKGROUND: Hepatobiliary tuberculosis includes miliary, tuberculous hepatitis or localized forms. The localised form is extremely uncommon and can mimic malignancy. Still rarer is its presentation as sclerosing cholangitis. CASE PRESENTATION: A 50 year male presented with acute onset jaundice, significant weight loss and elevated liver enzymes with clinico-radiological suspicion of cholangiocarcinoma. A left hepatectomy was done and dilated bile ducts filled with caseous necrotic material were seen intra-operatively. Histopathology suggested localized hepatobiliary tuberculosis with features of secondary sclerosing cholangitis. CONCLUSION: Localised hepatobiliary tuberculosis can cause diagnostic difficulties and its possibility should be considered especially in endemic areas. PMID- 29179697 TI - Identification and analysis of glutathione S-transferase gene family in sweet potato reveal divergent GST-mediated networks in aboveground and underground tissues in response to abiotic stresses. AB - BACKGROUND: Sweet potato, a hexaploid species lacking a reference genome, is one of the most important crops in many developing countries, where abiotic stresses are a primary cause of reduction of crop yield. Glutathione S-transferases (GSTs) are multifunctional enzymes that play important roles in oxidative stress tolerance and cellular detoxification. RESULTS: A total of 42 putative full length GST genes were identified from two local transcriptome databases and validated by molecular cloning and Sanger sequencing. Sequence and intraspecific phylogenetic analyses revealed extensive differentiation in their coding sequences and divided them into eight subfamilies. Interspecific phylogenetic and comparative analyses indicated that most examined GST paralogs might originate and diverge before the speciation of sweet potato. Results from large-scale RNA seq and quantitative real-time PCR experiments exhibited extensive variation in gene-expression profiles across different tissues and varieties, which implied strong evolutionary divergence in their gene-expression regulation. Moreover, we performed five manipulated stress experiments and uncovered highly divergent stress-response patterns of sweet potato GST genes in aboveground and underground tissues. CONCLUSIONS: Our study identified a large number of sweet potato GST genes, systematically investigated their evolutionary diversification, and provides new insights into the GST-mediated stress-response mechanisms in this worldwide crop. PMID- 29179699 TI - Gastrointestinal tuberculosis following renal transplantation accompanied with septic shock and acute respiratory distress syndrome: a survival case presentation. AB - BACKGROUND: Post-transplant tuberculosis (PTTB) is a serious opportunistic infection in renal graft recipients with a 30-70 fold higher incidence compared to the general population. PTTB occurs most frequently within the first years after transplantation, manifesting as pulmonary or disseminated TB. Gastrointestinal TB (GITB) is a rare and potentially lethal manifestation of PTTB and may show delayed onset in renal transplant recipients due to the use of lower doses of immunosuppressants. Further, non-specificity of symptoms and the common occurrence of GI disorders in transplant recipients may delay diagnosis of GITB. CASE PRESENTATION: Here we report a rare survival case of isolated GITB in a renal transplant recipient, occurring seven years after transplantation. The patient's condition was complicated by severe sepsis with positive blood culture Staphylococcus haemolyticus, septic shock, multiple organ failure including acute respiratory distress syndrome (ARDS) and acute renal failure, requiring mechanical ventilation, vasopressor circulatory support and intermittent hemodialysis. Furthermore, nosocomial infections such as invasive aspergillosis and Pseudomonas aeruginosa occurred during hospitalization. Antituberculosis therapy (rifampicin, isoniazid, ethambutol and pyrazinamide) was initiated upon Mycobacterium confirmation. Moreover, treatment with voriconazole due to the Aspergillus flavus and meropenem due to the Pseudomonas aeruginosa was initiated, the former necessitating discontinuation of rifampicin. After 34 days, the patient was weaned from mechanical ventilation and was discharged to the pulmonary ward, followed by complete recovery. CONCLUSION: This case offers a guideline for the clinical management towards survival of GITB in transplant patients, complicated by septic shock and multiple organ failure, including acute renal injury and ARDS. PMID- 29179698 TI - Fast food diet-induced non-alcoholic fatty liver disease exerts early protective effect against acetaminophen intoxication in mice. AB - BACKGROUND: Acetaminophen (APAP) is a readily available and safe painkiller. However, its overdose is the most common cause of acute liver injury (ALI). Many predisposing factors contribute to susceptibility to APAP-induced ALI. Non alcoholic fatty liver disease (NAFLD), the major cause of chronic liver disease, is considered an important predictor of APAP-induced ALI, although the exact mechanism controversial. In this study, we aimed to elucidate the effects of NAFLD on APAP-induced ALI. METHODS: Two groups of mice, normal chow (NC) diet-fed and fast food (FF) diet-fed mice for 14 weeks, were further divided into two subgroups: intraperitoneally injected with either saline (NC-S and FF-S groups) or APAP (NC-A and FF-A groups). Biochemical tests, histological analysis, quantitative PCR, and western blotting were conducted. RESULTS: Alanine aminotransferase (ALT) level (199.0 +/- 39.0 vs. 63.8 +/- 7.4 IU/L, p < 0.05) and NAFLD activity score (0 vs. 4.5 +/- 0.22) were significantly higher in mice in FF S group than those in NC-S group. ALI features such as ALT level (8447.8 +/- 1185.3 vs. 836.6 +/- 185.1 IU/L, p < 0.001) and centrizonal necrosis were prominent and mRNA levels of Trib3 (RR, 1.81) was high in mice in the NC-A group. Levels of CYP2E1 and anti-inflammatory molecules such as PPAR-gamma, p62, and NRF2 were high in mice in the FF-A group. CONCLUSIONS: Our results showed that while the FF diet clearly induced non-alcoholic steatohepatitis and metabolic syndrome, NAFLD also attenuates APAP-induced ALI by inducing anti-inflammatory molecules such as PPAR-gamma. PMID- 29179701 TI - The enablers, barriers and preferences of accessing radiation therapy facilities in the rural developed world - a systematic review. AB - BACKGROUND: Utilisation of radiation therapy for regional Australia and around the world has been the focus of much health policy the last decade. Radiation therapy centres have been built in Australian regional and rural areas to improve access to radiation therapy and reduce the tyranny of distance as a barrier to access. After this the enablers, barriers and perceptions of patients has been evaluated to determine utilisation once centres have been built. Thisreview looks the impact of rural radiation services in the developed world, barriers and enablers of establishing a rural radiation centre, and patients' and service providers' perspectives and preferences around the uptake of rural radiation therapy. METHODS: Online search of peer reviewed literature was undertaken using MeSH terms relating to the topic. Inclusion criteria were regional radiation therapy centres in developing countries, any year of publication, in English, and qualitative or quantitative methodologies. Articles were reviewed by two authors with conflicts discussed with a third. RESULTS: Twenty three studies addressed the theme directly. Distance barriers have been overcome by building regional centres and health economic burden was lower for government service providers with this strategy. However distance still plays an important role in influencing uptake of radiation therapy. Cultural expectations, influence of the family doctor and perception of care was influential. Carer support, duration of displacement from home, financial impact of the required care and seasonal weather were practical factors on a patient's decision. CONCLUSIONS: Regional radiation therapy centres have improved access to radiation therapy in developing countries. However the complex nuances between socio-economic, cultural and health system factors that influence regional patient's decision making bears further consideration, as distance is not the only issue. PMID- 29179702 TI - Foveal microvasculature features of surgically closed macular hole using optical coherence tomography angiography. AB - BACKGROUND: To describe the features of foveal microvasculature using optical coherence tomography angiography (OCTA) and to determine the related clinical factors in eyes with surgically closed macular hole (MH). METHODS: A retrospective case series of 18 patients with unilateral MH was reviewed. The patients maintained complete hole closure after vitrectomy with inner limiting membrane (ILM) peeling for at least 12 months. The healthy fellow eyes were studied as controls. The foveal microvasculature of both eyes was examined by OCTA. The area of the foveal avascular zone (FAZ) and the vascular density (VD) ratio in the superficial and deep capillary plexuses (SCP and DCP) were determined after surgery. Several clinical factors including age, stage and dimensions of MH, papillofoveal distance, the extent of nasal displacement of the fovea after surgery, postoperative central foveal thickness, and outer-retina integrity were evaluated to determine any relationships with the OCTA parameters. RESULTS: The mean FAZ area in both the SCP and DCP (0.29 +/- 0.11 mm2 and 0.39 +/ 0.14 mm2) was significantly smaller than those of the controls (0.45 +/- 0.14 mm2 and 0.62 +/- 0.22 mm2) (p = 0.001 and <0.001, respectively). The mean VD ratio in the SCP (0.270 +/- 0.349) was similar to that of the controls (0.321 +/- 0.189) (p = 0.231); however, that in the DCP (0.321 +/- 0.189) was significantly lower than that of the controls (0.331 +/- 0.119) (p = 0.025). Only the extent of nasal displacement of the fovea was correlated with the DCP FAZ-area difference values between the study group and the controls (correlation coefficient = 0.577; p = 0.012). CONCLUSIONS: After successful MH surgery, the FAZ area in both the SCP and DCP was smaller and the VD ratio of the DCP was lower, suggesting a possible DCP vulnerability to tractional stress. As the FAZ area of the DCP in closed-MH eyes became smaller than that in the controls, the fovea was less displaced toward the optic disc, possibly reflecting a lack of retinal redundancy caused by horizontal stretching accompanied by foveal displacement. PMID- 29179700 TI - Awareness, discussion and non-prescribed use of HIV pre-exposure prophylaxis among persons living with HIV/AIDS in Italy: a Nationwide, cross-sectional study among patients on antiretrovirals and their treating HIV physicians. AB - BACKGROUND: Before Pre-Exposure Prophylaxis (PrEP) was officially recommended and made available, a few surveys among gay and bisexual men, and persons living with HIV/AIDS (PLWHA), identified an informal use of antiretrovirals (ARVs) for PrEP among HIV-negative individuals. Before PrEP availability in Italy, we aimed to assess whether PLWHA in Italy shared their ARVs with HIV-negative individuals, whether they knew people who were on PrEP, and describe the level of awareness and discussion on this preventive measure among them and people in their close circle. METHODS: Two anonymous questionnaires investigating personal characteristics and PrEP awareness, knowledge, and experience were proposed to HIV specialists and their patients on ARVs in a one-week, cross-sectional survey (December 2013-January 2014). Among PLWHA, a Multivariable Logistic Regression analysis was conducted to identify factors associated with PrEP discussion with peers (close circle and/or HIV associations), and experience (use in close circle and/or personal ARV sharing). RESULTS: Eighty-seven specialists in 31 representative Infectious Diseases departments administered the questionnaire to 1405 PLWHA. Among specialists, 98% reported awareness, 65% knew the dosage schedule, and 14% had previously suggested or prescribed PrEP. Among PLWHA, 45.6% were somehow aware, discussed or had direct or indirect experience of PrEP: 38% "had heard" of PrEP, 24% were aware of studies in HIV-negative individuals demonstrating a risk reduction through the use of ARVs, 22% had discussed PrEP, 12% with peers; 9% reported PrEP use in close circle and 1% personal ARV sharing. Factors predictive of either PrEP discussion with peers or experience differed between men and women, but across all genders were mainly related to having access to information, with HIV association membership being the strongest predictor. CONCLUSIONS: At a time and place where there were neither official information nor proposals or interventions to guide public policies on PrEP in Italy, a significant number of PLWHA were aware of it, and approximately 10% reported PrEP use in their close circle, although they rarely shared their ARVs with uninfected people for this purpose. Official policies and PrEP availability, along with implementation programs, could avoid risks from uncontrolled PrEP procurement and self-administration practices. PMID- 29179703 TI - Is the content of guidelines/pathways a barrier for the integration of palliative Care in Chronic Heart Failure (CHF) and chronic pulmonary obstructive disease (COPD)? A comparison with the case of cancer in Europe. AB - BACKGROUND: There is a notable inequity in access to palliative care (PC) services between cancer and Chronic Heart Failure (CHF)/Chronic Obstructive Pulmonary Disease (COPD) patients which also translates into discrepancies in the level of integration of PC. By cross-examining the levels of PC integration in published guidelines/pathways for CHF/COPD and cancer in Europe, this study examines whether these discrepancies may be attributed to the content of the guidelines. DESIGN: A quantitative evaluation was made between integrated PC in published guidelines for cancer and CHF/COPD in Europe. The content of integrated PC in guidelines/pathways was measured using an 11 point integrated PC criteria tool (IPC criteria). A statistical analysis was carried out to detect similarities and differences in the level of integrated PC between the two groups. RESULTS: The levels of integration between CHF/COPD and cancer guidelines/pathways have been shown to be statistically similar. Moreover, the quality of evidence utilized and the date of development of the guidelines/pathways appear not to impact upon the PC integration in the guidelines. CONCLUSION: In Europe, the empirically observed imbalance in integration of PC for patients with cancer and CHF/COPD may only partially be attributed to the content of the guidelines/pathways that are utilized for the PC implementation. Given the similarities detected between cancer and CHF/COPD, other barriers appear to play a more prominent role. PMID- 29179705 TI - Vitrectomy with internal limiting membrane peeling versus inverted internal limiting membrane flap technique for macular hole-induced retinal detachment: a systematic review of literature and meta-analysis. AB - BACKGROUND: To evaluate the effects on vitrectomy with internal limiting membrane (ILM) peeling versus vitrectomy with inverted internal limiting membrane flap technique for macular hole-induced retinal detachment (MHRD). METHODS: Pubmed, Cochrane Library, and Embase were systematically searched for studies that compared ILM peeling with inverted ILM flap technique for macular hole-induced retinal detachment. The primary outcomes are the rate of retinal reattachment and the rate of macular hole closure 6 months later after initial surgery, the secondary outcome is the postoperative best-corrected visual acuity (BCVA) 6 months later after initial surgery. RESULTS: Four studies that included 98 eyes were selected. All the included studies were retrospective comparative studies. The preoperative best-corrected visual acuity was equal between ILM peeling and inverted ILM flap technique groups. It was indicated that the rate of retinal reattachment (odds ratio (OR) = 0.14, 95% confidence interval (CI):0.03 to 0.69; P = 0.02) and macular hole closure (OR = 0.06, 95% CI:0.02 to 0.19; P < 0.00001) after initial surgery was higher in the group of vitrectomy with inverted ILM flap technique than that in the group of vitrectomy with ILM peeling. However, there was no statistically significant difference in postoperative best-corrected visual acuity (mean difference (MD) 0.18 logarithm of the minimum angle of resolution; 95% CI -0.06 to 0.43 ; P = 0.14) between the two surgery groups. CONCLUSION: Compared with ILM peeling, vitrectomy with inverted ILM flap technique resulted significantly higher of the rate of retinal reattachment and macular hole closure, but seemed does not improve postoperative best-corrected visual acuity. PMID- 29179706 TI - Intralobar pulmonary sequestration expanding toward the contralateral thorax: two case reports. AB - BACKGROUND: Intralobar pulmonary sequestration (ILS) is defined as a portion of parenchyma that is contained within the normal pleural investment of the lung but not connected to the tracheobronchial tree, and supplied by anomalous systemic arteries. As ILS is enveloped within the lobe of the normal lung, it is extremely rare for ILS to invade into the mediastinum. We report two atypical cases of infants with ILS expanded toward the posterior mediastinum and contralateral thorax through the pulmonary ligament. CASE PRESENTATION: The first case involved a baby boy diagnosed at 30 weeks gestation with a cystic area in his right lower lobe. A chest computed tomography (CT) scan at 29 days of life showed low-density masses in the right lower lung and posterior mediastinum. A complete thoracoscopic right lower lobectomy was performed at 19 months of age. After ligation of the aberrant systemic artery, the mediastinal mass was pulled into the right pleural cavity. The mass was observed to connect to the right lower lobe mass as a segment of lung parenchyma situated within the normal pleural investment of the lung, and the patient was diagnosed with ILS. The second case involved the detection by chest CT of a left lower lung cystic mass that protruded into the posterior mediastinum and contralateral chest of a one-month old baby girl. A complete thoracoscopic left lower lobectomy was performed at the age of 18 months, and the cystic mass located in the right thoracic cavity was pulled easily into the left pleural cavity and resected. An anomalous systemic artery was identified and ligated, and the patient was also diagnosed with ILS. CONCLUSIONS: As the pulmonary ligament consists of two layers of mediastinal pleura, lower lung ILS with its visceral pleura covering can, though rarely, protrude into the mediastinum through the pulmonary ligament. Our two extremely rare cases of infants with ILS expanded toward the posterior mediastinum and contralateral thorax were successfully treated using a unilateral thoracoscopic approach. Pre-surgical differential diagnosis of mediastinal masses using contrast-enhanced multiple detector CT is important in informing the appropriate surgical approach. PMID- 29179704 TI - Sertad1 antagonizes iASPP function by hindering its entrance into nuclei to interact with P53 in leukemic cells. AB - BACKGROUND: As the important suppressor of P53, iASPP is found to be overexpressed in leukemia, and functions as oncogene that inhibited apoptosis of leukemia cells. Sertad1 is identified as one of the proteins that can bind with iASPP in our previous study by two-hybrid screen. METHODS: Co-immunoprecipitation and immunofluorescence were perfomed to identified the interaction between iASPP and Sertad1 protein. Westernblot and Real-time quantitative PCR were used to determine the expression and activation of proteins. Cell proliferation assays, cell cycle and cell apoptosis were examined by flow cytometric analysis. RESULTS: iASPP combined with Sertad1 in leukemic cell lines and the interaction occurred in the cytoplasm near nuclear membrane. iASPP could interact with Sertad1 through its Cyclin-A, PHD-bromo, C terminal domain, except for S domain. Overexpression of iASPP in leukemic cells resulted in the increased cell proliferation and resistance to apoptosis induced by chemotherapy drugs. While overexpression of iASPP and Sertad1 at the same time could slow down the cell proliferation, lead the cells more vulnerable to the chemotherapy drugs, the resistance to chemotherapeutic drug in iASPPhi leukemic cells was accompanied by Puma protein expression. Excess Sertad1 protein could tether iASPP protein in the cytoplasm, further reduced the binding between iASPP and P53 in the nucleus. CONCLUSIONS: Sertad1 could antagonize iASPP function by hindering its entrance into nuclei to interact with P53 in leukemic cells when iASPP was in the stage of overproduction. PMID- 29179707 TI - Selective impairment of decision making under ambiguity in alexithymia. AB - BACKGROUND: Alexithymia is characterised by difficulties identifying and describing emotions. Few studies have investigated how alexithymia influences decision-making under different conditions (ambiguity and risk). This study aimed to examine whether alexithymia contributes to impairment in decision-making. METHOD: This study included 42 participants with high scores in the Chinese version of Toronto Alexithymia Scale (alexithymia group), and 44 matched subjects with low scores (control group). Decision-making was measured using the Iowa Gambling Task (IGT) and the Game of Dice Task (GDT). RESULTS: The main findings of this study revealed selective deficits in IGT performance for the alexithymia group, while GDT performance was unimpaired when compared with the control group. In IGT, total netscores were lower for the alexithymia group compared to the control group, particularly with regard to block 5. Moreover, the alexithymia individuals selected significantly more adverse cards than the controls, indicating significant decision-making impairments. CONCLUSION: Alexithymia selectively influences decision-making under ambiguity. PMID- 29179708 TI - Comparing doctors' legal compliance across three Australian states for decisions whether to withhold or withdraw life-sustaining medical treatment: does different law lead to different decisions? AB - BACKGROUND: Law purports to regulate end-of-life care but its role in decision making by doctors is not clear. This paper, which is part of a three-year study into the role of law in medical practice at the end of life, investigates whether law affects doctors' decision-making. In particular, it considers whether the fact that the law differs across Australia's three largest states - New South Wales (NSW), Victoria and Queensland - leads to doctors making different decisions about withholding and withdrawing life-sustaining treatment from adults who lack capacity. METHODS: A cross-sectional postal survey of the seven specialties most likely to be involved in end-of-life care in the acute setting was conducted between 18 July 2012 and 31 January 2013. The sample comprised all medical specialists in emergency medicine, geriatric medicine, intensive care, medical oncology, palliative medicine, renal medicine and respiratory medicine on the AMPCo Direct database in those three Australian states. The survey measured medical specialists' level of legal compliance, and reasons for their decisions, concerning the withholding or withdrawal of life-sustaining treatment. Multivariable logistic regression was used to examine predictors of legal compliance. Linear regression was used to examine associations between the decision about life-sustaining treatment and the relevance of factors involved in making these decisions, as well as state differences in these associations. RESULTS: Response rate was 32% (867/2702). A majority of respondents in each state said that they would provide treatment in a hypothetical scenario, despite an advance directive refusing it: 72% in NSW and Queensland; 63% in Victoria. After applying differences in state law, 72% of Queensland doctors answered in accordance with local law, compared with 37% in Victoria and 28% in NSW (p < 0.001). Doctors reported broadly the same decision-making approach despite differences in local law. CONCLUSIONS: Law appears to play a limited role in medical decision-making at the end of life with doctors prioritising patient related clinical and ethical considerations. Different legal frameworks in the three states examined did not lead to different decisions about providing treatment. More education is needed about law and its role in this area, particularly where law is inconsistent with traditional practice. PMID- 29179709 TI - Measuring inconsistency in research ethics committee review. AB - BACKGROUND: The review of human participant research by Research Ethics Committees (RECs) or Institutional Review Boards (IRBs) is a complex multi faceted process that cannot be reduced to an algorithm. However, this does not give RECs/ IRBs permission to be inconsistent in their specific requirements to researchers or in their final opinions. In England the Health Research Authority (HRA) coordinates 67 committees, and has adopted a consistency improvement plan including a process called "Shared Ethical Debate" (ShED) where multiple committees review the same project. Committee reviews are compared for consistency by analysing the resulting minutes. METHODS: We present a description of the ShED process. We report an analysis of minutes created by research ethics committees participating in two ShED exercises, and compare them to minutes produced in a published "mystery shopper" exercise. We propose a consistency score by defining top themes for each exercise, and calculating the ratio between top themes and total themes identified by each committee for each ShED exercise. RESULTS: Our analysis highlights qualitative differences between the ShED 19, ShED 20 and "mystery shopper" exercises. The quantitative measure of consistency showed only one committee across the three exercises with more than half its total themes as top themes (ratio of 0.6). The average consistency scores for the three exercises were 0.23 (ShED19), 0.35 (ShED20) and 0.32 (mystery shopper). There is a statistically significant difference between the ShED 19 exercise, and the ShED 20 and mystery shopper exercises. CONCLUSIONS: ShED exercises are effective in identifying inconsistency between ethics committees and we describe a scoring method that could be used to quantify this. However, whilst a level of inconsistency is probably inevitable in research ethics committee reviews, studies must move beyond the ShED methodology to understand why inconsistency occurs, and what an acceptable level of inconsistency might be. PMID- 29179710 TI - Enhancing integrated palliative care: what models are appropriate? A cross-case analysis. AB - BACKGROUND: Effective integration between hospices, palliative care services and other local health care services to support patients with palliative care needs is an important international priority. A previous model suggests that integration involves a cumulative stepped process of engagement with other organisations labelled as 'support, supplant or supplement', but the extent to which this model currently applies in the United Kingdom is unknown. We aimed to investigate accounts of hospice integration with local health care providers, using the framework provided by the model, to determine how service users and healthcare professionals perceived palliative care services and the extent of integration experienced. METHODS: Longitudinal organisational case study methods were employed using qualitative serial interviews (interval 3 months) with patients and family carers focusing on how services responded to their needs; and group interviews with health professionals. Data were audio-recorded, transcribed verbatim, and analysed by qualitative content analysis and combined across data sources. RESULTS: The study focused on four hospices in northern England, including 34 patients (diagnosis: 17 cancer, 10 COPD, 7 heart failure), 65% female, mean age 66 (range 44-89), 13 family carers of these patients (48% partners), and 23 health care professionals. While some care fell short of expectations, all patients reported high levels of satisfaction and valued continuity of care and efficient information sharing. All hospices supported and supplemented local providers, with three hospices also supplanting local provision by providing in-patient facilities. CONCLUSION: UK hospices predominantly operate in ways that support and supplement other providers. In addition, some also supplant local services, taking over direct responsibility and funding in-patient care. They all contributed to integration with local services, with greater blurring of boundaries than defined by the original model. Integrated care offers the necessary flexibility to respond to changes in patient needs, however, constraints from funding drivers and a lack of clear responsibilities in the UK can result in shortfalls in optimal service delivery. Integrating hospice care with local healthcare services can help to address demographic changes, predominantly more frail older people, and disease factors, including the needs of those with non-malignant conditions. This model, tested in the UK, could serve as an example for other countries. PMID- 29179711 TI - A systematic review of data mining and machine learning for air pollution epidemiology. AB - BACKGROUND: Data measuring airborne pollutants, public health and environmental factors are increasingly being stored and merged. These big datasets offer great potential, but also challenge traditional epidemiological methods. This has motivated the exploration of alternative methods to make predictions, find patterns and extract information. To this end, data mining and machine learning algorithms are increasingly being applied to air pollution epidemiology. METHODS: We conducted a systematic literature review on the application of data mining and machine learning methods in air pollution epidemiology. We carried out our search process in PubMed, the MEDLINE database and Google Scholar. Research articles applying data mining and machine learning methods to air pollution epidemiology were queried and reviewed. RESULTS: Our search queries resulted in 400 research articles. Our fine-grained analysis employed our inclusion/exclusion criteria to reduce the results to 47 articles, which we separate into three primary areas of interest: 1) source apportionment; 2) forecasting/prediction of air pollution/quality or exposure; and 3) generating hypotheses. Early applications had a preference for artificial neural networks. In more recent work, decision trees, support vector machines, k-means clustering and the APRIORI algorithm have been widely applied. Our survey shows that the majority of the research has been conducted in Europe, China and the USA, and that data mining is becoming an increasingly common tool in environmental health. For potential new directions, we have identified that deep learning and geo-spacial pattern mining are two burgeoning areas of data mining that have good potential for future applications in air pollution epidemiology. CONCLUSIONS: We carried out a systematic review identifying the current trends, challenges and new directions to explore in the application of data mining methods to air pollution epidemiology. This work shows that data mining is increasingly being applied in air pollution epidemiology. The potential to support air pollution epidemiology continues to grow with advancements in data mining related to temporal and geo-spacial mining, and deep learning. This is further supported by new sensors and storage mediums that enable larger, better quality data. This suggests that many more fruitful applications can be expected in the future. PMID- 29179712 TI - The costs and benefits of water fluoridation in NZ. AB - BACKGROUND: Implementing community water fluoridation involves costs, but these need to be considered against the likely benefits. We aimed to assess the cost benefit and cost-effectiveness of water fluoridation in New Zealand (NZ) in terms of expenditure and quality-adjusted life years. METHODS: Based on published studies, we determined the risk reduction effects of fluoridation, we quantified its health benefits using standardised dental indexes, and we calculated financial savings from averted treatment. We analysed NZ water supplies to estimate the financial costs of fluoridation. We devised a method to represent dental caries experience in quality-adjusted life years. RESULTS: Over 20 years, the net discounted saving from adding fluoride to reticulated water supplies supplying populations over 500 would be NZ$1401 million, a nine times pay-off. Between 8800 and 13,700 quality-adjusted life years would be gained. While fluoridating reticulated water supplies for large communities is cost-effective, it is unlikely to be so with populations smaller than 500. CONCLUSIONS: Community water fluoridation remains highly cost-effective for all but very small communities. The health benefits-while (on average) small per person-add up to a substantial reduction in the national disease burden across all ethnic and socioeconomic groups. PMID- 29179713 TI - Analysis of the characteristics of cracked teeth and evaluation of pulp status according to periodontal probing depth. AB - BACKGROUND: The purpose of this study was to analyze the characteristics of cracked teeth and to evaluate pulp status according to periodontal probing depth (PPD). METHODS: A total of 182 cracked teeth were included. The location and type of the cracked teeth, age and gender of the patients, restoration type, pulp status, PPD, and radiographic findings were analyzed. RESULTS: Mandibular second molars (25.3%) were the most frequently involved teeth, followed by mandibular first molars (22.5%), maxillary first molars (22.0%), and maxillary second molars (17.6%). The patient age was most frequently 50-59 years. Cracks occurred mainly in nonbonded restorations, such as gold (26.9%), and were usually found in intact teeth (37.9%). A total of 103 teeth (56.6%) had an initial PPD of less than 3 mm, while 40 (22.0%) had a PPD of 4-6 mm, and 39 (21.4%) had PPD of 7 mm or more. A total of 33 cracked teeth (18.1%) were diagnosed with pulp necrosis, 40 (22.0%) with irreversible pulpitis, and 97 (53.3%) with reversible pulpitis. The incidence of pulp necrosis was 31.8% among cracked teeth with a PPD of 4-6 mm, and 28.6% among those with a PPD of 7 mm or more. CONCLUSIONS: Cracks occurred mainly in molar teeth, and were commonly found in intact teeth with no restoration. Patients with cracked teeth were most frequently aged 50-59 years. Cracked teeth showing a PPD of more than 4 mm were more likely to show pulp necrosis. PMID- 29179715 TI - The role of health policy in the burden of breast cancer in Brazil. AB - BACKGROUND: Breast cancer affects millions of women worldwide, particularly in Brazil, where public healthcare system is an important model in health organization and the cost of chronic disease has affected the economy in the first decade of the twenty-first century. The aim was to evaluate the role of health policy in the burden of breast cancer in Brazil between 2004 and 2014. METHODS: Secondary analysis was performed in 2017 with Brazilian Health Ministry official data, extracted from the Department of Informatics of the National Health System. Age-standardized mortality and the age-standardized incidence of hospital admission by breast cancer were calculated per 100,000 people. Public healthcare costs were converted to US dollars. Regression analysis was performed to estimate the trend of breast cancer rates and healthcare costs, and principal component analysis was performed to estimate a cost factor. Stata(r) 11.0 was utilized. RESULTS: Between 2004 to 2014, the age-standardized rates of breast cancer mortality and the incidence of hospital admission and public healthcare costs increased. There was a positive correlation between breast cancer and healthcare public costs, mainly influenced by governmental strategies. CONCLUSIONS: Governmental strategies are effective against the burden of breast cancer in Brazil. PMID- 29179714 TI - Influence of age, gender, and radiographic features on the deltoid splitting approach for surgical osteosynthesis in displaced proximal humerus fractures: a comparison study. AB - BACKGROUND: The deltoid splitting approach has recently been widely adopted to facilitate less invasive procedures for proximal humerus fractures. However, there are still concerns regarding its effectiveness in aging people and in cases involving complex fractures. This study was conducted to evaluate the efficacy of a proximal humeral locking plate using the anterolateral deltoid splitting approach and to specifically examine the effect of patient age, gender, and fracture pattern on surgical outcomes. METHODS: Forty-two cases of proximal humeral fractures treated using the deltoid splitting approach and locking plate fixation were reviewed. Outcome differences were evaluated in terms of age, gender distribution, and radiographic analysis based on the Neer Classification. The influence of the surgical approach was further investigated by age-matched paired analysis after subdividing patients into two age groups (younger than 60 years vs. older than 60 years; N = 21, in each group). RESULTS: In total, 41 patients (98%) demonstrated fracture union. The average Constant score was 80.4. No significant differences were found between patients younger than 60 years, and the older patients. Higher mean scores were found in men than in women (p = 0.448) and in simple fractures than in complex fractures (p = 0.454), without any significant differences. Better postoperative functional outcomes were observed when the humeral head-neck angle was greater than 105 degrees , with a significant difference (p = 0.000). Surgical complications were found in 16 patients (38%) without significant difference between two age groups (p = 0.268). The most common complication was screw penetration. CONCLUSIONS: Anterolateral deltoid splitting using locking plate fixation provided a feasible alternative for surgery of proximal humerus fractures in different age groups and yielded comparable outcomes when the neck-shaft angle was properly restored. Surgeons must be cautious regarding potential complications, especially with screw penetration when using the locking plate through a less invasive approach. TRIAL REGISTRATION: ISRCTN75494532 . Trial Date: 2017/01/31. PMID- 29179716 TI - Patient perspectives on engagement in decision-making in early management of non ST elevation acute coronary syndrome: a qualitative study. AB - BACKGROUND: Surveys of patients suggest many want to be actively involved in treatment decisions for acute coronary syndromes. However, patient experiences of their engagement and participation in early phase decision-making have not been well described. METHODS: We performed a patient led qualitative study to explore patient experiences with decision-making processes when admitted to hospital with non-ST elevation acute coronary syndrome. Trained patient-researchers conducted the study via a three-phase approach using focus groups and semi-structured interviews and employing grounded theory methodology. RESULTS: Twenty patients discharged within one year of a non-ST elevation acute coronary syndrome participated in the study. Several common themes emerged. First, patients characterized the admission and early treatment of ACS as a rapidly unfolding process where they had little control. Participants felt they played a passive role in early phase decision-making. Furthermore, participants described feeling reduced capacity for decision-making owing to fear and mental stress from acute illness, and therefore most but not all participants were relieved that expert clinicians made decisions for them. Finally, once past the emergent phase of care, participants wanted to retake a more active role in their treatment and follow-up plans. CONCLUSIONS: Patients admitted with ACS often do not take an active role in initial clinical decisions, and are satisfied to allow the medical team to direct early phase care. These results provide important insight relevant to designing patient-centered interventions in ACS and other urgent care situations. PMID- 29179717 TI - Does having a usual primary care provider reduce patient self-referrals in rural China's rural multi-tiered medical system? A retrospective study in Qianjiang District, China. AB - INTRODUCTION: Within China's multi-tiered medical system, many patients seek care in higher-tiered hospitals without a referral by a primary-care provider. This trend, generally referred to as patient self-referral behavior, may reduce the efficiency of the health care system. This study seeks to test the hypothesis that having a usual primary care provider could reduce patients' self-referral behavior. METHODS: We obtained medical records of 832 patients who were hospitalized for common respiratory diseases from township hospitals in Qianjiang District of Chongqing City during 2012-2014. Logit regressions were performed to examine the association between having a township hospital as a usual provider and self-referring to a county hospital after being discharged from a township hospital, while controlling for patients' gender, age, income, education, severity of disease, distance to the nearest county hospital and the general quality of the township hospitals in their community. A propensity score weighting approach was applied. RESULTS: We found that having a usual primary care provider was associated with a lower likelihood of self-referral (odds ratio = 0.58, 95% confidence interval [CI] =0.41-0.82), and a 9% (95% CI: -14%, - 3%) reduction in the probability of patients' self-referral behavior. DISCUSSION/CONCLUSION: The results suggest that establishing a long-term relationship between patients and primary care providers may enhance the patient physician relationship and reduce patients' tendency for unnecessary use of medical resources. PMID- 29179718 TI - What is the impact of a clinically related readmission measure on the assessment of hospital performance? AB - BACKGROUND: The Hospital Readmission Reduction Program (HRRP) penalizes hospitals for high all-cause unplanned readmission rates. Many have expressed concern that hospitals serving patient populations with more comorbidities, lower incomes, and worse self-reported health status may be disproportionately penalized by readmissions that are not clinically related to the index admission. The impact of including clinically unrelated readmissions on hospital performance is largely unknown. We sought to determine if a clinically related readmission measure would significantly alter the assessment of hospital performance. METHODS: We analyzed Medicare claims for beneficiaries in Michigan admitted for pneumonia and joint replacement from 2011 to 2013. We compared each hospital's 30-day readmission rate using specifications from the HRRP's all-cause unplanned readmission measure to values calculated using a clinically related readmission measure. RESULTS: We found that the mean 30-day readmission rates were lower when calculated using the clinically related readmission measure (joint replacement: all-cause 5.8%, clinically related 4.9%, p < 0.001; pneumonia: all cause 12.5%, clinically related 11.3%, p < 0.001)). The correlation of hospital ranks using both methods was strong (joint replacement: 0.95 (p < 0.001), pneumonia: 0.90 (p < 0.001)). CONCLUSIONS: Our findings suggest that, while greater specificity may be achieved with a clinically related measure, clinically unrelated readmissions may not impact hospital performance in the HRRP. PMID- 29179719 TI - Effect of dendritic cell-cytokine-induced killer cells in patients with advanced colorectal cancer combined with first-line treatment. AB - BACKGROUND: Surgical resection combined with adjuvant chemotherapy is considered as the gold-standard treatment for advanced colorectal cancer patients. These patients have a poor 5-year survival rate of 5% or less. Furthermore, a large dose of chemotherapy can produce adverse side effects and severe toxicity. Therefore, this retrospective study aimed to evaluate the efficacy of dendritic cell-cytokine-induced killer (DC-CIK) cell infusion as an adjuvant therapy in patients with advanced colorectal cancer combined with first-line treatment. METHODS: A total of 142 patients with stage III/IV colorectal carcinoma who had been treated with first-line therapy were included in this study. Among these patients, 71 patients received first-line treatment only (non-DC-CIK group), while the other 71 patients who had similar demographic and clinical characteristics received a DC-CIK cell infusion combined with first-line treatment (DC-CIK group). These patients were followed up until August 2014. Data were analyzed by Kaplan-Meier and Cox regression. RESULTS: Our results showed that the 5-year overall survival (OS) rate for the DC-CIK group versus the non-DC CIK group was 41.3 versus 19.4% (p = 0.001) and the 5-year progression-free survival (PFS) rate for the DC-CIK group versus the non-DC-CIK group was 57.4 versus 33.6% (p = 0.022). CONCLUSIONS: Our results showed that patients with advanced colorectal cancer might benefit from DC-CIK immunotherapy combined with first-line therapy by significantly prolonging 5-year OS and PFS. PMID- 29179720 TI - Depression comorbid with tuberculosis and its impact on health status: cross sectional analysis of community-based data from 48 low- and middle-income countries. AB - BACKGROUND: Depression in tuberculosis increases the risk for adverse health outcomes. However, little is known about comorbid depression and tuberculosis in the general population. Thus, we assessed the association between depression and tuberculosis, and the decrements in health status associated with this comorbidity in 48 low- and middle-income countries. METHODS: Cross-sectional, community-based data from the World Health Survey on 242,952 individuals aged >= 18 years were analyzed. Based on the World Mental Health Survey version of the Composite International Diagnostic Interview, past 12-month depression was categorized into depressive episode, brief depressive episode, subsyndromal depression, and no depression. Health status across six domains (cognition, interpersonal activities, sleep/energy, self-care, mobility, pain/discomfort) was assessed. Multivariable logistic and linear regression analyses were performed to assess the associations. RESULTS: The prevalence of depressive episode among those with and without tuberculosis was 23.7% and 6.8%, respectively (P < 0.001). Tuberculosis was associated with a 1.98 (95% CI 1.47-2.67), 1.75 (95% CI 1.26 2.42), and 3.68 (95% CI 3.01-4.50) times higher odds for subsyndromal depression, brief depressive episode, and depressive episode, respectively. Depressive episode co-occurring with tuberculosis was associated with significantly worse health status across all six domains compared to tuberculosis alone. Interaction analysis showed that depression significantly amplifies the association between TB and difficulties in self-care but not in other health domains. CONCLUSIONS: Depression is highly prevalent in adults with tuberculosis, and is associated with worse health status compared to tuberculosis without depression. Public health efforts directed to the recognition and management of depression in people with tuberculosis may lead to better outcomes. PMID- 29179721 TI - Apigenin, by activating p53 and inhibiting STAT3, modulates the balance between pro-apoptotic and pro-survival pathways to induce PEL cell death. AB - BACKGROUND: Apigenin is a flavonoid widely distributed in plant kingdom that exerts cytotoxic effects against a variety of solid and haematological cancers. In this study, we investigated the effect of apigenin against primary effusion lymphoma (PEL), a KSHV-associated B cell lymphoma characterized by a very aggressive behavior, displaying constitutive activation of STAT3 as well as of other oncogenic pathways and harboring wtp53. METHODS: Cell death was assessed by trypan blue exclusion assay, FACS analysis as well as by biochemical studies. The latter were also utilized to detect the occurrence of autophagy and the molecular mechanisms leading to the activation of both processes by apigenin. FACS analysis was used to measure the intracellular ROS utilizing DCFDA. RESULTS: We show that apigenin induced PEL cell death and autophagy along with reduction of intracellular ROS. Mechanistically, apigenin activated p53 that induced catalase, a ROS scavenger enzyme, and inhibited STAT3, the most important pro-survival pathway in PEL, as assessed by p53 silencing. On the other hand, STAT3 inhibition by apigenin resulted in p53 activation, since STAT3 negatively influences p53 activity, highlighting a regulatory loop between these two pathways that modulates PEL cell death/survival. CONCLUSION: The findings of this study demonstrate that apigenin may modulate pro-apoptotic and pro-survival pathways representing a valid therapeutic strategy against PEL.

AB - BACKGROUND: Chemotherapeutic drugs used for cancer therapy frequently encounter multiple-drug resistance (MDR). Nanoscale carriers that can target tumors to accumulate and release drugs intracellularly have the greatest potential for overcoming MDR. Glucose transporter-1 (GLUT-1) and glutathione (GSH) overexpression in cancer cells was exploited to assemble aminoglucose (AG) conjugated, redox-responsive nanomicelles from a single disulfide bond-bridged block polymer of polyethylene glycol and polylactic acid (AG-PEG-SS-PLA). However, whether this dual functional vector can overcome MDR in lung cancer is unknown. RESULTS: In this experiment, AG-PEG-SS-PLA was synthetized successfully, and paclitaxel (PTX)-loaded AG-PEG-SS-PLA (AG-PEG-SS-PLA/PTX) nanomicelles exhibited excellent physical properties. These nanomicelles show enhanced tumor targeting as well as drug accumulation and retention in MDR cancer cells. Caveolin-dependent endocytosis is mainly responsible for nanomicelle internalization. After internalization, the disulfide bond of AG-PEG-SS-PLA is cleaved in the presence of high intracellular glutathione levels, causing the hydrophobic core to become a polar aqueous solution, which subsequently results in nanomicelle disassembly and the rapid release of encapsulated PTX. Reduced drug resistance was observed in cancer cells in vitro. The caspase-9 and caspase 3 cascade was activated by the AG-PEG-SS-PLA/PTX nanomicelles through upregulation of the pro-apoptotic proteins Bax and Bid and suppression of the anti-apoptotic protein Bcl-2, thereby increasing apoptosis. Furthermore, significantly enhanced tumor growth inhibition was observed in nude mice bearing A549/ADR xenograft tumors after the administration of AG-PEG-SS-PLA/PTX nanomicelles via tail injection. CONCLUSIONS: These promising results indicate that AG-PEG-SS-PLA/PTX nanomicelles could provide the foundation for a paradigm shift in MDR cancer therapy.

AB - BACKGROUND: The Healthy Lifestyles Programme (HeLP) was a novel school-located intervention for 9-10 year olds, designed to prevent obesity by changing patterns of child behaviour through the creation of supportive school and home environments using dynamic and creative delivery methods. This paper reports on both the quantitative and qualitative data regarding the implementation of the HeLP intervention in the definitive cluster randomised controlled trial, which was part of the wider process evaluation. METHODS: Mixed methods were used to collect data on intervention uptake, fidelity of delivery in terms of content and quality of delivery of the intervention, as well as school and child engagement with the programme. Data were collected using registers of attendance, observations and checklists, field notes, focus groups with children and semi structured interviews with teachers. Qualitative data were analysed thematically and quantitative data were summarized using descriptive statistics. RESULTS: All 16 intervention schools received a complete or near complete programme (94-100%), which was delivered in the spirit in which it had been designed. Of the 676 children in the intervention schools, over 90% of children participated in each phase of HeLP; 92% of children across the socio-economic spectrum were deemed to be engaged with HeLP and qualitative data revealed a high level of enjoyment by all children, particularly to the interactive drama workshops. Further evidence of child engagment with the programme was demonstrated by children's clear understanding of programme messages around marketing, moderation and food labelling. Thirteen of the intervention schools were deemed to be fully engaged with HeLP and qualitative data revealed a high level of teacher 'buy in', due to the programme's compatability with the National Curriculum, level of teacher support and use of innovative and creative delivery methods by external drama practitioners. CONCLUSION: Our trial shows that it is possible to successfully scale up complex school-based interventions, engage schools and children across the socio-economic spectrum and deliver an intervention as designed. As programme integrity was maintained throughout the HeLP trial, across all intervention schools, we can be confident that the trial findings are a true reflection of the effectiveness of the intervention, enabling policy recommendations to be made.

AB - Inflammatory neuropathies are rare autoimmune-mediated disorders affecting the peripheral nervous system. Considerable progress has recently been made in understanding pathomechanisms of these disorders which will be essential for developing novel diagnostic and therapeutic strategies in the future. Here, we summarize our current understanding of antigenic targets and the relevance of new immunological concepts for inflammatory neuropathies. In addition, we provide an overview of available animal models of acute and chronic variants and how new diagnostic tools such as magnetic resonance imaging and novel therapeutic candidates will benefit patients with inflammatory neuropathies in the future. This review thus illustrates the gap between pre-clinical and clinical findings and aims to outline future directions of development. PMID- 29179725 TI - High resolution chromosomal microarray analysis in paediatric obsessive compulsive disorder. AB - BACKGROUND: Obsessive-Compulsive Disorder (OCD) is a common and chronic disorder in which a person has uncontrollable, reoccurring thoughts and behaviours. It is a complex genetic condition and, in case of early onset (EO), the patients manifest a more severe phenotype, and an increased heritability. Large (>500 kb) copy number variations (CNVs) previously associated with autism and schizophrenia have been reported in OCD. Recently, rare CNVs smaller than 500 kb overlapping risk loci for other neurodevelopmental conditions have also been reported in OCD, stressing the importance of examining CNVs of any size range. The aim of this study was to further investigate the role of rare and small CNVs in the aetiology of EO-OCD. METHODS: We performed high-resolution chromosomal microarray analysis in 121 paediatric OCD patients and in 124 random controls to identify rare CNVs (>50 kb) which might contribute to EO-OCD. RESULTS: The frequencies and the size of the observed rare CNVs in the patients did not differ from the controls. However, we observed a significantly higher frequency of rare CNVs affecting brain related genes, especially deletions, in the patients (OR = 1.98, 95% CI 1.02-3.84; OR = 3.61, 95% CI 1.14-11.41, respectively). Similarly, enrichment analysis of CNVs gene content, performed with three independent methods, confirmed significant clustering of predefined genes involved in synaptic/brain related functional pathways in the patients but not in the controls. In two patients we detected de-novo CNVs encompassing genes previously associated with different neurodevelopmental disorders (NRXN1, ANKS1B, UHRF1BP1). CONCLUSIONS: Our results further strengthen the role of small rare CNVs, particularly deletions, as susceptibility factors for paediatric OCD. PMID- 29179726 TI - Modulation of the functional association between the HIV-1 intasome and the nucleosome by histone amino-terminal tails. AB - BACKGROUND: Stable insertion of the retroviral DNA genome into host chromatin requires the functional association between the intasome (integrase.viral DNA complex) and the nucleosome. The data from the literature suggest that direct protein-protein contacts between integrase and histones may be involved in anchoring the intasome to the nucleosome. Since histone tails are candidates for interactions with the incoming intasomes we have investigated whether they could participate in modulating the nucleosomal integration process. RESULTS: We show here that histone tails are required for an optimal association between HIV-1 integrase (IN) and the nucleosome for efficient integration. We also demonstrate direct interactions between IN and the amino-terminal tail of human histone H4 in vitro. Structure/function studies enabled us to identify amino acids in the carboxy-terminal domain of IN that are important for this interaction. Analysis of the nucleosome-binding properties of catalytically active mutated INs confirmed that their ability to engage the nucleosome for integration in vitro was affected. Pseudovirus particles bearing mutations that affect the IN/H4 association also showed impaired replication capacity due to altered integration and re-targeting of their insertion sites toward dynamic regions of the chromatin with lower nucleosome occupancy. CONCLUSIONS: Collectively, our data support a functional association between HIV-1 IN and histone tails that promotes anchoring of the intasome to nucleosomes and optimal integration into chromatin. PMID- 29179728 TI - Site-specific selection reveals selective constraints and functionality of tumor somatic mtDNA mutations. AB - BACKGROUND: Previous studies have indicated that tumor mitochondrial DNA (mtDNA) mutations are primarily shaped by relaxed negative selection, which is contradictory to the critical roles of mtDNA mutations in tumorigenesis. Therefore, we hypothesized that site-specific selection may influence tumor mtDNA mutations. METHODS: To test our hypothesis, we developed the largest collection of tumor mtDNA mutations to date and evaluated how natural selection shaped mtDNA mutation patterns. RESULTS: Our data demonstrated that both positive and negative selections acted on specific positions or functional units of tumor mtDNAs, although the landscape of these mutations was consistent with the relaxation of negative selection. In particular, mutation rate (mutation number in a region/region bp length) in complex V and tRNA coding regions, especially in ATP8 within complex V and in loop and variable regions within tRNA, were significantly lower than those in other regions. While the mutation rate of most codons and amino acids were consistent with the expectation under neutrality, several codons and amino acids had significantly different rates. Moreover, the mutations under selection were enriched for changes that are predicted to be deleterious, further supporting the evolutionary constraints on these regions. CONCLUSION: These results indicate the existence of site-specific selection and imply the important role of the mtDNA mutations at some specific sites in tumor development. PMID- 29179727 TI - Mild endoplasmic reticulum stress ameliorates lipopolysaccharide-induced neuroinflammation and cognitive impairment via regulation of microglial polarization. AB - BACKGROUND: Neuroinflammation, which ultimately leads to neuronal loss, is considered to play a crucial role in numerous neurodegenerative diseases. The neuroinflammatory process is characterized by the activation of glial cells such as microglia. Endoplasmic reticulum (ER) stress is commonly associated with impairments in neuronal function and cognition, but its relationship and role in neurodegeneration is still controversial. Recently, it was confirmed that nonharmful levels of ER stress protected against experimental Parkinson's disease. Here, we investigated mild ER stress-based regulation of lipopolysaccharide (LPS)-driven neuroinflammation in rats and in primary microglia. METHODS: Male Sprague-Dawley (SD) rats received the intracerebroventricular injection of the ER stress activator tunicamycin (TM) with or without intraperitoneal injection of the ER stress stabilizer sodium 4 phenylbutyrate (4-PBA) 1 h before LPS administration. The levels of neuroinflammation and memory dysfunction were assessed 24 h after treatment. In addition, the effect of mild ER stress on microglia was determined in vitro. RESULTS: Here, we found that low doses of TM led to mild ER stress without cell or organism lethality. We showed that mild ER stress preconditioning reduced microglia activation and neuronal death as well as improved LPS-induced memory impairment in rats. In addition, pre-exposure to nonlethal doses of TM in microglia showed significant protection against LPS-induced proinflammatory cytokine production and M1/2b polarization. However, sodium 4-PBA, a compound that ameliorates ER stress, ablated this protective effect in vivo and in vitro. CONCLUSIONS: Based on our findings, we conclude that the mild ER stress not only limits the accumulation of misfolded proteins but also protects tissues from harmful endotoxemia insults. Therefore, ER stress preconditioning has potential therapeutic value for the treatment of neurodegenerative diseases. PMID- 29179729 TI - Deficiency of innate-like T lymphocytes in chronic obstructive pulmonary disease. AB - BACKGROUND: Based on the phenotypic and functional characteristics unconventional T-lymphocytes such as invariant natural killer T (iNKT) cells and mucosal associated invariant T (MAIT) cells link the innate and adaptive immune responses. Up to now data are scarce about their involvement in pulmonary disorders including chronic obstructive pulmonary disease (COPD). This study explores simultaneously the frequencies of iNKT and MAIT cells in the peripheral blood and sputum of stable and exacerbating COPD patients. METHODS: By means of multicolor flow cytometry frequencies of total iNKT and MAIT cells and their subsets were enumerated in peripheral blood and sputum samples of healthy controls, and COPD patients. In addition, gene expression of TCR for iNKT, MAIT cells, and CD1d, MR1 were assessed by qPCR in the study cohorts. RESULTS: Percentages of total iNKT and MAIT cells were dramatically dropped in blood, and reduced numbers of iNKT cells were observed in the sputum of COPD patients. Furthermore decreased DN and increased CD4+ iNKT subsets, while increased DN and decreased CD8+ MAIT subpopulations were measured in the blood of COPD patients. Reduced invariant TCR mRNA levels in COPD patients had confirmed these previous findings. The mRNA expression of CD1d and MR1 were increased in stable and exacerbating COPD patients; however both molecules were decreased upon antibiotic and systemic steroid treatments. CONCLUSIONS: Our results support the notion that both invariant T-cell populations are affected in COPD. Further detailed analysis of invariant T cells could shed more light into the complex interactions of these lymphocyte groups in COPD pathogenesis. PMID- 29179730 TI - Control under times of uncertainty: the relationship between hospital competition and physician-patient disputes. AB - BACKGROUND: Recently, cases of medical disputes and even acts of violence toward physicians by patients in China have been escalating. It remains unknown whether competition improves the patient-physician relationship. METHODS: This paper analyzes the relationship between hospital competition and the probability of medical disputes occurrence according to the theory of social control. Data from all hospitals in the Sichuan province of China from 2011 to 2014 were included in the study. The fixed radius approach with GIS information was employed to define hospital market, and the differences in competition over time and across regions were utilized. Our analysis is based on the fixed effect estimation, which accounts for the time-invariant unobserved heterogeneity among hospitals. RESULTS: We found an inversed U-shaped relationship between HHI and the likelihood of medical disputes. As beneath either situation of monopoly or full competition, the burst of physician-patient dispute was downward into a valley, but it rises and then falls again with the increase of HHI, it reached the peak at the typical semi-market hospital competition structure. CONCLUSIONS: Our results highlight the probability of change in disputes occurrence with the transition of hospital competition and its psychological explanation, providing implications for China's future health reform. PMID- 29179731 TI - Can routine data be used to support cancer clinical trials? A historical baseline on which to build: retrospective linkage of data from the TACT (CRUK 01/001) breast cancer trial and the National Cancer Data Repository. AB - BACKGROUND: Randomised clinical trials (RCTs) are the gold standard for evaluating new cancer treatments. They are, however, expensive to conduct, particularly where long-term follow-up of participants is required. Tracking participants via routine datasets could provide a cost-effective alternative for ascertaining follow-up information required to evaluate disease outcomes. This project explores the potential for routine data to inform cancer trials, using, the historical National Cancer Data Repository (NCDR) for English NHS sites and, for validation, mature data available from the TACT trial. METHODS: Datasets were matched using patients' NHS number, date of birth (dob) and name/initials. Demographics, clinical characteristics and outcomes were assessed for agreement and completeness. Overall survival was compared between NCDR and TACT. RESULTS: A total of 3151 patients underwent linkage; 3047 (96.7%) of which had matched records. Extensive cleaning was required for some registry data fields, e.g. cause of death, whilst others had large amounts of missing data, e.g. tumour size (22.1%). Other data had high levels of matching such as dob (99.6%) and date of death (89.6%). There was no evidence of differential survival rates (8-year survival: TACT = 75% (95% CI 73, 76); NCDR = 76% (95% CI 74, 77)). CONCLUSIONS: Data quality and completeness requires improvement before routine data could be used for RCTs. Introduction of new routine datasets, including COSD, is welcomed although reporting of disease-recurrence events remains a concern. Prospective validation of such datasets is required before RCTs can confidently switch patient follow-up to utilise routinely collected NHS-based data.

PMID- 29179733 TI - A comparison of results of empirical studies of supplementary search techniques and recommendations in review methodology handbooks: a methodological review. AB - BACKGROUND: The purpose and contribution of supplementary search methods in systematic reviews is increasingly acknowledged. Numerous studies have demonstrated their potential in identifying studies or study data that would have been missed by bibliographic database searching alone. What is less certain is how supplementary search methods actually work, how they are applied, and the consequent advantages, disadvantages and resource implications of each search method. The aim of this study is to compare current practice in using supplementary search methods with methodological guidance. METHODS: Four methodological handbooks in informing systematic review practice in the UK were read and audited to establish current methodological guidance. Studies evaluating the use of supplementary search methods were identified by searching five bibliographic databases. Studies were included if they (1) reported practical application of a supplementary search method (descriptive) or (2) examined the utility of a supplementary search method (analytical) or (3) identified/explored factors that impact on the utility of a supplementary method, when applied in practice. RESULTS: Thirty-five studies were included in this review in addition to the four methodological handbooks. Studies were published between 1989 and 2016, and dates of publication of the handbooks ranged from 1994 to 2014. Five supplementary search methods were reviewed: contacting study authors, citation chasing, handsearching, searching trial registers and web searching. CONCLUSIONS: There is reasonable consistency between recommended best practice (handbooks) and current practice (methodological studies) as it relates to the application of supplementary search methods. The methodological studies provide useful information on the effectiveness of the supplementary search methods, often seeking to evaluate aspects of the method to improve effectiveness or efficiency. In this way, the studies advance the understanding of the supplementary search methods. Further research is required, however, so that a rational choice can be made about which supplementary search strategies should be used, and when. PMID- 29179732 TI - Drug repurposing for the treatment of glioblastoma multiforme. AB - BACKGROUND: Glioblastoma Multiforme is the deadliest type of brain tumor and is characterized by very poor prognosis with a limited overall survival. Current optimal therapeutic approach has essentially remained unchanged for more than a decade, consisting in maximal surgical resection followed by radiotherapy plus temozolomide. MAIN BODY: Such a dismal patient outcome represents a compelling need for innovative and effective therapeutic approaches. Given the development of new drugs is a process presently characterized by an immense increase in costs and development time, drug repositioning, finding new uses for existing approved drugs or drug repurposing, re-use of old drugs when novel molecular findings make them attractive again, are gaining significance in clinical pharmacology, since it allows faster and less expensive delivery of potentially useful drugs from the bench to the bedside. This is quite evident in glioblastoma, where a number of old drugs is now considered for clinical use, often in association with the first line therapeutic intervention. Interestingly, most of these medications are, or have been, widely employed for decades in non-neoplastic pathologies without relevant side effects. Now, the refinement of their molecular mechanism(s) of action through up-to-date technologies is paving the way for their use in the therapeutic approach of glioblastoma as well as other cancer types. SHORT CONCLUSION: The spiraling costs of new antineoplastic drugs and the long time required for them to reach the market demands a profoundly different approach to keep lifesaving therapies affordable for cancer patients. In this context, repurposing can represent a relatively inexpensive, safe and fast approach to glioblastoma treatment. To this end, pros and cons must be accurately considered. PMID- 29179734 TI - An integrated digital/clinical approach to smoking cessation in lung cancer screening: study protocol for a randomized controlled trial. AB - BACKGROUND: Delivering effective tobacco dependence treatment that is feasible within lung cancer screening (LCS) programs is crucial for realizing the health benefits and cost savings of screening. Large-scale trials and systematic reviews have demonstrated that digital cessation interventions (i.e. web-based and text message) are effective, sustainable over the long-term, scalable, and cost efficient. Use of digital technologies is commonplace among older adults, making this a feasible approach within LCS programs. Use of cessation treatment has been improved with models that proactively connect smokers to treatment rather than passive referrals. Proactive referral to cessation treatment has been advanced through healthcare systems changes such as modifying the electronic health record to automatically link smokers to treatment. METHODS: This study evaluates the impact of a proactive enrollment strategy that links LCS-eligible smokers with an evidence-based intervention comprised of a web-based (WEB) program and integrated text messaging (TXT) in a three-arm randomized trial with repeated measures at one, three, six, and 12 months post randomization. The primary outcome is biochemically confirmed abstinence at 12 months post randomization. We will randomize 1650 smokers who present for a clinical LCS to: (1) a usual care control condition (UC) which consists of Ask-Advise-Refer; (2) a digital (WEB + TXT) cessation intervention; or (3) a digital cessation intervention combined with tobacco treatment specialist (TTS) counseling (WEB + TXT + TTS). DISCUSSION: The scalability and sustainability of a digital intervention may represent the most cost-effective and feasible approach for LCS programs to proactively engage large numbers of smokers in effective cessation treatment. We will also evaluate the impact and cost-effectiveness of adding proven clinical intervention provided by a TTS. We expect that a combined digital/clinical intervention will yield higher quit rates than digital alone, but that it may not be as cost-effective or feasible for LCS programs to implement. This study is innovative in its use of interoperable, digital technologies to deliver a sustainable, scalable, high impact cessation intervention and to facilitate its integration within clinical practice. It will add to the growing knowledge base about the overall effectiveness of digital interventions and their role in the healthcare delivery system.

PMID- 29179735 TI - Ficus sycomorus extract reversed behavioral impairment and brain oxidative stress induced by unpredictable chronic mild stress in rats. AB - BACKGROUND: Stress, regardless of its nature is nowadays recognized as one of the major risk factors for neuropsychiatric diseases, such as mood and anxiety disorders. The brain compared with other organs is more vulnerable to oxidative damage mainly due to its high rate of oxygen consumption, abundant lipid content, and relative insufficiency of antioxidant enzymes. Thus, the identification of neural mechanisms underlying resistance and vulnerability to stress is of crucial importance in understanding the pathophysiology of neuropsychiatric disorders and in developing new treatments, since the existing ones are for several reasons subject to increasing limitations. This study was aimed to assess the effects of hydromethanolic extract of Ficus sycomorus stem bark on depression, anxiety and memory impairment induced by unpredictable chronic mild stress (UCMS) in rats. METHODS: These effects were studied using anxiety-related behavior, depression related behavior, anhedonia-like behavior and the Y maze task. Sucrose test was performed twice (before and after UCMS) to assess anhedonia in rats. Liquid chromatography-mass spectrometry analysis of the extract were performed. The antioxidant activities of the extract were assessed using total glutathione (GSH) content and malondialdehyde (MDA) level (lipid peroxidation) in the rat temporal lobe homogenates. RESULTS: The extract of F. sycomorus in a dose of 100 mg/kg significantly increased the sucrose consumption and the swimming time which had been reduced by the unpredictable chronic mild stress (p < 0.001). The extract also significantly reduced (p < 0.01) the latency time in the novelty-suppressed feeding test. In the elevated plus-maze, the extract (100 and 200 mg/kg) significantly reduced (p < 0.01) the time and the number of entries into the closed arms. The treatment with the extracts also significantly increased alternation in the Y-maze (p < 0.01 for 100 mg/kg). The extract significantly increased the total GSH content and reduced MDA level in rat temporal lobe. For the LC-MS analysis, the major compound in the extract was a flavonoid with formula C22H28O14. CONCLUSIONS: F. sycomorus reversed the harmful effects of UCMS on mood and behaviors in rats and it possesses an antidepressant property that is at least in part mediated through the oxidative pathway. PMID- 29179736 TI - Phylogenetic analysis of the core histone doublet and DNA topo II genes of Marseilleviridae: evidence of proto-eukaryotic provenance. AB - BACKGROUND: While the genomes of eukaryotes and Archaea both encode the histone fold domain, only eukaryotes encode the core histone paralogs H2A, H2B, H3, and H4. With DNA, these core histones assemble into the nucleosomal octamer underlying eukaryotic chromatin. Importantly, core histones for H2A and H3 are maintained as neofunctionalized paralogs adapted for general bulk chromatin (canonical H2 and H3) or specialized chromatin (H2A.Z enriched at gene promoters and cenH3s enriched at centromeres). In this context, the identification of core histone-like "doublets" in the cytoplasmic replication factories of the Marseilleviridae (MV) is a novel finding with possible relevance to understanding the origin of eukaryotic chromatin. Here, we analyze and compare the core histone doublet genes from all known MV genomes as well as other MV genes relevant to the origin of the eukaryotic replisome. RESULTS: Using different phylogenetic approaches, we show that MV histone domains encode obligate H2B-H2A and H4-H3 dimers of possible proto-eukaryotic origin. MV core histone moieties form sister clades to each of the four eukaryotic clades of canonical and variant core histones. This suggests that MV core histone moieties diverged prior to eukaryotic neofunctionalizations associated with paired linear chromosomes and variant histone octamer assembly. We also show that MV genomes encode a proto eukaryotic DNA topoisomerase II enzyme that forms a sister clade to eukaryotes. This is a relevant finding given that DNA topo II influences histone deposition and chromatin compaction and is the second most abundant nuclear protein after histones. CONCLUSIONS: The combined domain architecture and phylogenomic analyses presented here suggest that a primitive origin for MV histone genes is a more parsimonious explanation than horizontal gene transfers + gene fusions + sufficient divergence to eliminate relatedness to eukaryotic neofunctionalizations within the H2A and H3 clades without loss of relatedness to each of the four core histone clades. We thus suggest MV histone doublet genes and their DNA topo II gene possibly were acquired from an organism with a chromatinized replisome that diverged prior to the origin of eukaryotic core histone variants for H2/H2A.Z and H3/cenH3. These results also imply that core histones were utilized ancestrally in viral DNA compaction and/or protection from host endonucleases. PMID- 29179737 TI - Dose-dependent effect of daptomycin on the artificial prolongation of prothrombin time in coagulation abnormalities: in vitro verification. AB - BACKGROUND: Several studies have reported that daptomycin induced artificial prolongation of prothrombin time (PT) in some test reagents, particularly in warfarin users. However, it remains unknown whether the artificial prolongation can be affected by coagulation abnormalities other than the use of warfarin. Thus, we investigated the effect of daptomycin on PT with two types of coagulation abnormalities. METHODS: Plasma samples were pooled by four groups: healthy volunteers (Plasma A), warfarin users with a PT-international normalized ratio (INR) of approximately 2.0 (Plasma B) or 3.0 (Plasma C), and patients with liver cirrhosis with a PT-INR of approximately 2.0 (Plasma D). Plasma A was composed of plasma from two healthy individuals (9 mL from each individual). Plasma B, C, and D were composed of plasma from 36 patients (0.5 mL from each patient). Daptomycin was added to each sample to create solutions with several concentrations (0-150 MUg/mL). The PT-INR for each solution was measured with three PT reagents. Linear regression analyses were used to determine the association between daptomycin concentration and PT-INR. The relative change in PT-INR due to daptomycin concentrations was calculated. RESULTS: Strong linear correlations were observed between daptomycin concentrations and PT-INR for all the plasma groups and reagents (R2 > 0.7, P < 0.01). At a daptomycin concentration of 150 MUg/mL, the relative increase of PT-INR was >=10% in the majority of the plasma groups with an elevated baseline PT-INR in all reagents tested. CONCLUSIONS: Daptomycin induced the artificial prolongation of PT-INR in a concentration-dependent manner, particularly in plasma samples with an elevated baseline PT-INR. PT should be evaluated at the trough levels of daptomycin. PMID- 29179738 TI - Laser-modified titanium surfaces enhance the osteogenic differentiation of human mesenchymal stem cells. AB - BACKGROUND: Titanium surfaces have been modified by various approaches with the aim of improving the stimulation of osseointegration. Laser beam (Yb-YAG) treatment is a controllable and flexible approach to modifying surfaces. It creates a complex surface topography with micro and nano-scaled patterns, and an oxide layer that can improve the osseointegration of implants, increasing their usefulness as bone implant materials. METHODS: Laser beam irradiation at various fluences (132, 210, or 235 J/cm2) was used to treat commercially pure titanium discs to create complex surface topographies. The titanium discs were investigated by scanning electron microscopy, X-ray diffraction, and measurement of contact angles. The surface generated at a fluence of 235 J/cm2 was used in the biological assays. The behavior of mesenchymal stem cells from an umbilical cord vein was evaluated using a 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) assay, a mineralization assay, and an alkaline phosphatase activity assay and by carrying out a quantitative real-time polymerase chain reaction for osteogenic markers. CHO-k1 cells were also exposed to titanium discs in the MTT assay. RESULTS: The best titanium surface was that produced by laser beam irradiation at 235 J/cm2 fluence. Cell proliferation analysis revealed that the CHO-k1 and mesenchymal stem cells behaved differently. The laser-processed titanium surface increased the proliferation of CHO-k1 cells, reduced the proliferation of mesenchymal stem cells, upregulated the expression of the osteogenic markers, and enhanced alkaline phosphatase activity. CONCLUSIONS: The laser-treated titanium surface modulated cellular behavior depending on the cell type, and stimulated osteogenic differentiation. This evidence supports the potential use of laser-processed titanium surfaces as bone implant materials, and their use in regenerative medicine could promote better outcomes. PMID- 29179739 TI - Subjective cognitive impairment and brain structural networks in Chinese gynaecological cancer survivors compared with age-matched controls: a cross sectional study. AB - BACKGROUND: Subjective cognitive impairment can be a significant and prevalent problem for gynaecological cancer survivors. The aims of this study were to assess subjective cognitive functioning in gynaecological cancer survivors after primary cancer treatment, and to investigate the impact of cancer treatment on brain structural networks and its association with subjective cognitive impairment. METHODS: This was a cross-sectional survey using a self-reported questionnaire by the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) to assess subjective cognitive functioning, and applying DTI (diffusion tensor imaging) and graph theoretical analyses to investigate brain structural networks after primary cancer treatment. RESULTS: A total of 158 patients with gynaecological cancer (mean age, 45.86 years) and 130 age-matched non-cancer controls (mean age, 44.55 years) were assessed. Patients reported significantly greater subjective cognitive functioning on the FACT-Cog total score and two subscales of perceived cognitive impairment and perceived cognitive ability (all p values <0.001). Compared with patients who had received surgery only and non-cancer controls, patients treated with chemotherapy indicated the most altered global brain structural networks, especially in one of properties of small-worldness (p = 0.004). Reduced small-worldness was significantly associated with a lower FACT-Cog total score (r = 0.412, p = 0.024). Increased characteristic path length was also significantly associated with more subjective cognitive impairment (r = -0.388, p = 0.034). CONCLUSION: When compared with non cancer controls, a considerable proportion of gynaecological cancer survivors may exhibit subjective cognitive impairment. This study provides the first evidence of brain structural network alteration in gynaecological cancer patients at post treatment, and offers novel insights regarding the possible neurobiological mechanism of cancer-related cognitive impairment (CRCI) in gynaecological cancer patients. As primary cancer treatment can result in a more random organisation of structural brain networks, this may reduce brain functional specificity and segregation, and have implications for cognitive impairment. Future prospective and longitudinal studies are needed to build upon the study findings in order to assess potentially relevant clinical and psychosocial variables and brain network measures, so as to more accurately understand the specific risk factors related to subjective cognitive impairment in the gynaecological cancer population. Such knowledge could inform the development of appropriate treatment and rehabilitation efforts to ameliorate cognitive impairment in gynaecological cancer survivors. PMID- 29179740 TI - Childhood disability in Malawi: a population based assessment using the key informant method. AB - BACKGROUND: Epidemiological data on childhood disability are lacking in Low and Middle Income countries (LMICs) such as Malawi, hampering effective service planning and advocacy. The Key Informant Method (KIM) is an innovative, cost effective method for generating population data on the prevalence and causes of impairment in children. The aim of this study was to use the Key Informant Method to estimate the prevalence of moderate/severe, hearing, vision and physical impairments, intellectual impairments and epilepsy in children in two districts in Malawi and to estimate the associated need for rehabilitation and other services. METHODS: Five hundred key informants (KIs) were trained to identify children in their communities who may have the impairment types included in this study. Identified children were invited to attend a screening camp where they underwent assessment by medical professionals for moderate/severe hearing, vision and physical impairments, intellectual impairments and epilepsy. RESULTS: Approximately 15,000 children were identified by KIs as potentially having an impairment of whom 7220 (48%) attended a screening camp. The estimated prevalence of impairments/epilepsy was 17.3/1000 children (95% CI: 16.9-17.7). Physical impairment (39%) was the commonest impairment type followed by hearing impairment (27%), intellectual impairment (26%), epilepsy (22%) and vision impairment (4%). Approximately 2100 children per million population could benefit from physiotherapy and occupational therapy and 300 per million are in need of a wheelchair. An estimated 1800 children per million population have hearing impairment caused by conditions that could be prevented or treated through basic primary ear care. Corneal opacity was the leading cause of vision impairment. Only 50% of children with suspected epilepsy were receiving medication. The majority (73%) of children were attending school, but attendance varied by impairment type and was lowest among children with multiple impairments (38%). CONCLUSION: Using the KIM this study identified more than 2500 children with impairments in two districts of Malawi. As well as providing data on child disability, rehabilitation and referral service needs which can be used to plan and advocate for appropriate services and interventions, this method study also has an important capacity building and disability awareness raising component. PMID- 29179741 TI - Dietary energy drives the dynamic response of bovine rumen viral communities. AB - BACKGROUND: Rumen microbes play a greater role in host energy acquisition than that of gut-associated microbes in monogastric animals. Although genome-enabled advancements are providing access to the vast diversity of uncultivated microbes, our understanding of variables shaping rumen microbial communities is in its infancy. Viruses have been shown to impact microbial populations through a myriad of processes, including cell lysis and reprogramming of host metabolism. However, little is known about the processes shaping the distribution of rumen viruses or how viruses may modulate microbial-driven processes in the rumen. To this end, we investigated how rumen bacterial and viral community structure and function responded in five steers fed four randomized dietary treatments in a crossover design. RESULTS: Total digestible nutrients (TDN), a measure of dietary energy, best explained the variation in bacterial and viral communities. Additional ecological drivers of viral communities included dietary zinc content and microbial functional diversity. Using partial least squares regression, we demonstrate significant associations between the abundances of 267 viral populations and variables driving the variation in rumen viral communities. While rumen viruses were dynamic, 14 near ubiquitous viral populations were identified, suggesting the presence of a core rumen virome largely comprised of novel viruses. Moreover, analysis of virally encoded auxiliary metabolic genes (AMGs) indicates rumen viruses have glycosidic hydrolases to potentially augment the breakdown of complex carbohydrates to increase energy production. Other AMGs identified have a role in redirecting carbon to the pentose phosphate pathway and one carbon pools by folate to boost viral replication. CONCLUSIONS: We demonstrate that rumen bacteria and viruses have differing responses and ecological drivers to dietary perturbation. Our results show that rumen viruses have implications for understanding the structuring of the previously identified core rumen microbiota and impacting microbial metabolism through a vast array of AMGs. AMGs in the rumen appear to have consequences for microbial metabolism that are largely in congruence with the current paradigm established in marine systems. This study provides a foundation for future hypotheses regarding the dynamics of viral-mediated processes in the rumen. PMID- 29179742 TI - Neuroimaging genomics in psychiatry-a translational approach. AB - Neuroimaging genomics is a relatively new field focused on integrating genomic and imaging data in order to investigate the mechanisms underlying brain phenotypes and neuropsychiatric disorders. While early work in neuroimaging genomics focused on mapping the associations of candidate gene variants with neuroimaging measures in small cohorts, the lack of reproducible results inspired better-powered and unbiased large-scale approaches. Notably, genome-wide association studies (GWAS) of brain imaging in thousands of individuals around the world have led to a range of promising findings. Extensions of such approaches are now addressing epigenetics, gene-gene epistasis, and gene environment interactions, not only in brain structure, but also in brain function. Complementary developments in systems biology might facilitate the translation of findings from basic neuroscience and neuroimaging genomics to clinical practice. Here, we review recent approaches in neuroimaging genomics-we highlight the latest discoveries, discuss advantages and limitations of current approaches, and consider directions by which the field can move forward to shed light on brain disorders. PMID- 29179743 TI - Visceral and subcutaneous abdominal adiposity and pulmonary function in 30-year old adults: a cross-sectional analysis nested in a birth cohort. AB - BACKGROUND: Several studies have verified body fat distribution in association with pulmonary function (PF), mainly waist circumference, but few have used measures able to distinguish abdominal fat compartments. The present study aims to verify the association of visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) with PF measures. METHODS: In 1982, all hospital births occurring in Pelotas, Brazil, were identified and those livebirths have been followed. In 2012-13, the cohort participants were evaluated and VAT and SAT measured using ultrasound; forced expiratory volume in the first second (FEV1) or forced vital capacity (FVC) were patronized in z-scores stratified by sex. The associations were verified using crude and adjusted linear regressions. RESULTS: The present analyses comprised 3438 individuals (1721 women). VAT was inversely associated with spirometric parameters, in both crude and adjusted models. SAT showed inverse associations in the crude analyzes in males and a positive trend after adjustment, except for SAT and FVC in males. To each centimeter of VAT, mean adjusted FEV1 z-scores decreased 0.072 (95% CI -0.107; -0.036) in men and 0.127 (95% CI -0.164; -0.090) in women, and FVC z-scores decreased -0.075 (95% CI -0.111; -0.039) and 0.121 (95% CI -0.158; -0.083), in men and women, respectively. CONCLUSIONS: VAT has a consistent inverse association with FEV1 and FVC in both sexes. On the other hand, SAT showed inconsistent results with PF parameters. PMID- 29179745 TI - Reproducibility of the 75 g oral glucose tolerance test for the diagnosis of gestational diabetes mellitus in a sub-Saharan African population. AB - OBJECTIVE: To evaluate the reproducibility of the 75 g oral glucose tolerance test and factors associated with non-reproducible results in Cameroonian pregnant women. RESULTS: Twenty-seven of the 84 participants (32.1%) who did the first oral glucose tolerance test were diagnosed with gestational diabetes mellitus. There was no difference between the means of the glycaemic responses at T0 (p = 0.64), T30 (p = 0.08), T60 (p = 0.86), T90 (p = 0.51), and T120 (p = 0.34) between the two oral glucose tolerance test. Age (p = 0.001) and BMI (p = 0.001) were significantly associated with non-reproducible results. The reproducibility of the oral glucose tolerance test in this study was 74.2%, and the kappa statistic's 0.46. In conclusion, the results of the oral glucose tolerance test were reproducible in only 74.2% of pregnant women in this study. This highlights that a single oral glucose tolerance test for the diagnosis of gestational diabetes mellitus should be interpreted with caution. PMID- 29179744 TI - Levels, trends and correlates of unmet need for family planning among postpartum women in Indonesia: 2007-2015. AB - BACKGROUND: Although Indonesia has relatively high contraceptive prevalence, postpartum family planning (PP-FP) has not been a particular point of emphasis. This article reports the results of analyses undertaken in order to (1) better understand levels and trends in unmet need for family planning among postpartum women, (2) assess the extent to which unmet need is concentrated among particular population sub-groups, and (3) assess the policy priority that PP-FP should have in relation to other interventions. METHODS: The analyses were based on data from the 2007 and 2012 Indonesia Demographic and Health Surveys (IDHS) and the 2015 PMA2020 survey. Postpartum contraceptive use and unmet need were analyzed for fecund women who had given birth in the 3-5 years of preceding the respective surveys who were in the extended postpartum period at the time of the respective surveys. Factors associated with contraceptive use and unmet were assessed via multivariable logistic regressions using merged data from all three surveys. A wide range of biologic, demographic, socio-economic, geographic and programmatic factors were considered. RESULTS: Contraceptive use during the extended postpartum period is high in Indonesia, with more than 74% of post-partum women reporting currently using a family planning method in the 2015 PMA2020 survey. This is up from 68% in 2007 and 70% in 2012. Total unmet need was 28% in 2007, falling slightly to 23% in 2012 and 24% in 2015. However, the timing of contraceptive initiation is less than optimal. By six months postpartum, only 50% of mothers had begun contraceptive use. Unmet need was highest among older women, women with 4+ children, with limited knowledge of contraceptive methods, making fewer ANC visits, from poor families and residents of islands other than Java and Bali. CONCLUSION: Unmet need for family planning among postpartum women in Indonesia is low in comparison with other low- and middle-income countries. However, because of limited durations of exclusive breastfeeding, many Indonesian women do not initiate contraception early enough after delivering children. Given already high contraceptive prevalence, targeting postpartum women for increased programmatic attention would seem strategically prudent. PMID- 29179746 TI - Association of Interleukin-1 gene clusters polymorphisms with primary open-angle glaucoma: a meta-analysis. AB - BACKGROUND: Previous studies have associated the Interleukin-1 (IL-1) gene clusters polymorphisms with the risk of primary open-angle glaucoma (POAG). However, the results were not consistent. Here, we performed a meta-analysis to evaluate the role of IL-1 gene clusters polymorphisms in POAG susceptibility. METHODS: PubMed, EMBASE and Cochrane Library (up to July 15, 2017) were searched by two independent investigators. All case-control studies investigating the association between single-nucleotide polymorphisms (SNPs) of IL-1 gene clusters and POAG risk were included. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for quantifying the strength of association that has been involved in at least two studies. RESULTS: Five studies on IL-1beta rs16944 (c. 511C > T) (1053 cases and 986 controls), 4 studies on IL-1alpha rs1800587 (c. 889C > T) (822 cases and 714 controls), and 4 studies on IL-1beta rs1143634 (c. +3953C > T) (798 cases and 730 controls) were included. The results suggest that all three SNPs were not associated with POAG risk. Stratification analyses indicated that the rs1143634 has a suggestive associated with high tension glaucoma (HTG) under dominant (P = 0.03), heterozygote (P = 0.04) and allelic models (P = 0.02), however, the weak association was nullified after Bonferroni adjustments for multiple tests. CONCLUSIONS: Based on current meta-analysis, we indicated that there is lack of association between the three SNPs of IL-1 and POAG. However, this conclusion should be interpreted with caution and further well designed studies with large sample-size are required to validate the conclusion as low statistical powers. PMID- 29179747 TI - Optimal reduction of chemical oxygen demand and NH3-N from landfill leachate using a strongly resistant novel Bacillus salmalaya strain. AB - BACKGROUND: When the unavoidable waste generation is considered as damaging to our environment, it becomes crucial to develop a sustainable technology to remediate the pollutant source towards an environmental protection and safety. The development of a bioengineering technology for highly efficient pollutant removal is this regard. Given the high ammonia nitrogen content and chemical oxygen demand of landfill leachate, Bacillus salmalaya strain 139SI, a novel resident strain microbe that can survive in high ammonia nitrogen concentrations, was investigated for the bioremoval of ammonia nitrogen from landfill leachate. The treatability of landfill leachate was evaluated under different treatment parameters, such as temperature, inoculum dosage, and pH. RESULTS: Results demonstrated that bioaugmentation with the novel strain can potentially improve the biodegradability of landfill leachate. B. salmalaya strain 139SI showed high potential to enhance biological treatment given its maximum NH3-N and COD removal efficiencies. The response surface plot pattern indicated that within 11 days and under optimum conditions (10% v/v inoculant, pH 6, and 35 degrees C), B. salmalaya strain139SI removed 78% of ammonia nitrogen. At the end of the study, biological and chemical oxygen demands remarkably decreased by 88% and 91.4%, respectively. Scanning electron microscopy images revealed that ammonia ions covered the cell surface of B. salmalaya strain139SI. CONCLUSIONS: Therefore, novel resistant Bacillus salmalaya strain139SI significantly reduces the chemical oxygen demand and NH3-N content of landfill leachate. Leachate treatment by B. salmalaya strain 139SI within 11 days. PMID- 29179748 TI - Quantifying bone marrow inflammatory edema in the spine and sacroiliac joints with thresholding. AB - BACKGROUND: Psoriatic Arthritis (PsA) is a chronic inflammatory arthritis that develops in patients with psoriasis. Inflammatory edema in the spine may reflect subclinical disease activity and be a predictor of radiographic progression. A semi-quantitative method established by the spondyloarthritis research consortium of Canada (SPARCC) is commonly used to assess the disease activity in MR images of the spine. This study aims to evaluate thresholding for quantification of subtle bone marrow inflammation in the spine and the sacroiliac (SI) joints of patients with PsA and compare it with the SPARCC scoring system. METHODS: Short tau inversion recovery (STIR) MR images of the spine (N = 85) and the SI joints (N = 95) of patients with PsA (N = 41) were analyzed. A threshold was applied to visible bone marrow in order to mask areas with higher signal intensity, which are consistent with inflammation. These areas were considered as inflammatory lesions. The volume and relative signal intensity of the lesions were calculated. Results from thresholding were compared to SPARCC scores using linear mixed effects models. The specificity and sensitivity of thresholding were also calculated. RESULTS: A significant positive correlation between the volumes and mean relative signal intensities, which were calculated by thresholding analysis, and the SPARCC scores was detected for both spine (p < 0.001) and SI joints (p < 0.001). For the spine, thresholding had sensitivity and specificity of 83% and 76% respectively, while for the SI joints the values were 51% and 88% respectively. CONCLUSIONS: Thresholding allows quantification of subtle bone marrow inflammatory edema in patients with psoriatic arthritis, and could support SPARCC scoring of the spine. Improved image processing and inclusion of automatic segmentation are required for thresholding of STIR images to become a rapid and reliable method for quantitative measures of inflammation. TRIAL REGISTRATION: NCT02995460 (December 14, 2016) - Retrospectively registered. PMID- 29179749 TI - Evaluation of the three-in-one team-based care model on hierarchical diagnosis and treatment patterns among patients with diabetes: a retrospective cohort study using Xiamen's regional electronic health records. AB - BACKGROUND: Xiamen is a pilot city in China for hierarchical diagnosis and treatment reform of non-communicable diseases, especially diabetes. Since 2012, Xiamen has implemented a program called the "three-in-one", a team-based care model for the treatment of diabetes, which involves collaboration between diabetes specialists, general practitioners, and health managers. In addition, the program provides financial incentives to improve care, as greater accessibility to medications through community health care centers (CHCs). The aim of this study was to evaluate the effectiveness of these policies in shifting visits from general hospitals to CHCs for the treatment of type 2 diabetes mellitus (T2DM). METHOD AND MATERIALS: A retrospective observational cohort study was conducted using Xiamen's regional electronic health record (EHR) database, which included 90% of all patients registered since 2012. Logistic regression was used to derive the adjusted odds ratio (OR) for patients shifting from general hospitals to CHCs. Among patients treated at hospitals, Kaplan-Meier(KM) curves were constructed to evaluate the time from each policy introduction until the switch to CHCs. A k-means clustering analysis was conducted to identify patterns of patient care-seeking behavior. RESULTS: In total, 89,558 patients and 2,373,524 visits were included. In contrast to increased outpatient visits to general hospitals in China overall, the percentage of visits to CHCs in Xiamen increased from 29.7% in 2012 to 66.5% in 2016. The most significant and rapid shift occurred in later periods after full policy implementation. Three clusters of patients were identified with different levels of complications and health care-seeking frequency. All had similar responses to the policies. CONCLUSIONS: The "three-in-one" team-based care model showed promising results for building a hierarchical health care system in China. These policy reforms effectively increased CHCs utilization among diabetic patients. PMID- 29179750 TI - Safety evaluation of the interchangeable use of robenacoxib (OnsiorTM) tablets and solution for injection in dogs. AB - BACKGROUND: Robenacoxib (OnsiorTM) is a non-steroidal anti-inflammatory drug developed for canine and feline use for the control of pain and inflammation. It is available as both tablets and solution for injection. The objective of this safety study was to investigate the interchangeable use of two robenacoxib formulations in dogs using a novel study design alternating between oral tablets and subcutaneous injections. Thirty-two naive healthy 4-month dogs were enrolled in this 88-day study and were randomized among four groups to be untreated or to receive robenacoxib at the highest recommended or elevated dose rates. The dogs were administered three 20-day treatment cycles each separated by a 14-day washout period. Each 20-day cycle was comprised of 10 days of once daily oral administration, 3 days of subcutaneous administration, followed by further 7 days of oral administration (Groups 2 to 4). The control group (Group 1) received oral empty gelatin capsules or subcutaneous saline injections. Assessment of safety was based on general health observations, clinical observations, physical and neurological examinations including ophthalmological examinations, electrocardiographic examinations and clinical pathology evaluations, food and water consumption, body weight, and macroscopic and microscopic examinations. Blood samples were collected for pharmacokinetic evaluation. RESULTS: Blood concentrations of robenacoxib confirmed systemic exposure of all treated dogs. All dogs were in good health through study termination and there were no serious adverse events during the course of the study. No changes in body weight, food consumption, ophthalmic, neurological examinations, electrocardiograms, buccal mucosal blood times, clinical pathology or organ weight were attributable to robenacoxib formulation administration. Primary treatment-related abnormalities were of low incidence at all doses. They were confined to macroscopic and microscopic changes observed locally at the subcutaneous injection sites and microscopic findings within the gastrointestinal tract. These findings were as expected based on previous studies with robenacoxib solution for injection alone and the known properties of this class of compound and mode of administration. There were no adverse effects which could be attributed specifically to the interchangeable use of oral and injectable robenacoxib. CONCLUSIONS: Alternating regimens of robenacoxib tablets and solution for injection were well tolerated in healthy young dogs. PMID- 29179751 TI - Prospective phase-II-study evaluating postoperative radiotherapy of cervical and endometrial cancer patients using protons - the APROVE-trial. AB - BACKGROUND: The prognosis for patients with cervical or endometrial cancer has improved over the last decades. Thus, reducing therapy-related toxicity and impact on quality of life have become more and more important. With the development of new radiotherapy techniques like IMRT (Intensity-modulated radiotherapy) the incidence of acute and chronic toxicities has already been reduced. Nevertheless, rates of complications requiring medical treatment range from 0.7-8% according to literature. 7.7% of patients develop severe complications after 5 years with an increasing risk for complications of 0.3%/year. Particularly, the volume of the small and large bowel receiving low doses (15 Gy) has been shown to be a predictive factor for the development of higher bowel toxicity. With the introduction of proton therapy into clinical practice, there are new opportunities for optimization of organ at risk-sparing thus possibly reducing toxicity. METHODS/DESIGN: The APROVE study is a prospective single-center one-arm phase-II-study. Patients with cervical or endometrial cancer after surgical resection who have an indication for postoperative pelvic radiotherapy will be treated with proton therapy instead of the commonly used photon radiation. A total of 25 patients will be included in this trial. Patients will receive a dose of 45-50.4 GyE in 1.8 GyE fractions 5-6 times per week using active raster-scanning pencil beam proton radiation. Platinum-based chemotherapy can be administered if indicated. For treatment planning, rectum, sigma, large and small bowel, bladder and femoral heads are defined as organs at risk. The CTV is defined according to the RTOG consensus guidelines. DISCUSSION: The primary endpoint of the study is the evaluation of safety and treatment tolerability of pelvic radiation using protons defined as the lack of any CTC AE Grade 3 or 4 toxicity. Secondary endpoints are clinical symptoms and toxicity, quality of life and progression-free survival. The aim is to explore the potential of proton therapy as a new method for adjuvant pelvic radiotherapy to decrease the dose to the bowel, rectum and bladder thus reducing acute and chronic toxicity and improving quality of life.

PMID- 29179752 TI - Characteristics and determinants of clinical symptoms in radiographic lumbar spinal stenosis in a tertiary health care centre in sub-Saharan Africa. AB - BACKGROUND: Lumbar spinal stenosis (LSS) refers to narrowing of the lumbar central spinal canal, lateral recess, and/or neuro-foramina. Radiographic LSS plays an important role in clinical LSS but is not solely accountable for the presence of symptoms. We sought to characterise clinical LSS and to determine factors associated with presence of symptoms of LSS in patients with radiographic LSS in a sub Saharan Africa setting. METHODS: After prior ethical clearance, a case control study was done in a tertiary hospital in Douala-Cameroon, including 105 patients with radiographic LSS: 57 with symptoms of LSS (cases) and 58 with no symptoms (controls). Spinal stenosis was assessed using computed tomography (CT) scans. Data were analysed using SPSS version 23. RESULTS: The mean age of our study participants was 53.4 +/- 13.1 years. The mean age of onset of symptoms of LSS was 50.3 +/- 11.6 years and the most common symptoms were Low back pain (100.0%), radicular symptoms (98.2%) and neurogenic claudication (98.2%). Obesity (p < 0.001) and a high waist circumference (p = 0.002) were significantly associated with presence of LSS symptoms in persons with radiographic LSS. After adjusting for body mass index, a positive family history of low back pain (p = 0.004), vertebra lesion at L2 (p = 0.034), L3 (p = 0.002), L4 (p = 0.025) and multiple (p = 0.008) levels, degenerative disc protrusion (p = 0.044), disc lesion at L3-L4 (p = 0.001), L4-L5 (p = 0.011) and multiple (p = 0.046) levels were significantly associated with presence of symptoms of LSS in persons with radiographic LSS. CONCLUSION: Characteristics of clinical LSS have been described in this sub-Saharan Africa population. Obesity, a high waist circumference and a positive family history of low back pain are significantly associated with presence of symptoms of LSS in persons with radiographic LSS. PMID- 29179753 TI - Development and psychometric properties of a questionnaire to measure drug users' attitudes toward methadone maintenance treatment (DUAMMT) in Iran. AB - BACKGROUND: Assessing drug users' attitudes towards different kinds of addiction treatment is necessary to design tailored strategies. The aim of the present study is to develop and examine the psychometric properties of a new scale, called the DUAMMT, for assessing drug users' attitudes toward methadone maintenance treatment in Iran. METHODS: A multi-phase development method was applied in developing an instrument from February to December 2016. The item generation and scale development were performed through literature review, a qualitative approach, and interviews with an expert panel. Then, the psychometric properties of the scale were evaluated by means of cross-sectional studies with drug users. We performed an exploratory factor analysis, a confirmatory factor analysis, and item-scale correlations; and we tested the internal consistency of the scale. Furthermore, test-retest reliability was evaluated among an Iranian sample of drug users. RESULTS: The mean age of participants was 34.12 years. The exploratory factor analysis revealed four factors (perceived barriers, perceived concerns, methadone side effects, and perceived positive effects) containing 17 items that jointly accounted for 60.53% of the observed variance. The confirmatory factor analysis showed a model with appropriate fitness for the data. The Cronbach's alpha coefficient for the subscales ranged from .70 to .79. The intra-class correlation coefficient (ICC) ranged from .774 to .970, which is well above the acceptable threshold. CONCLUSIONS: The findings of the present study suggest that the DUAMMT is a valid and reliable instrument to measure drug users' attitudes toward methadone maintenance treatment. The DUAMMT can be applied at the start of treatment so that clinical intervention can be targeted to promote retention in treatment. PMID- 29179754 TI - Quantitative evaluation of subchondral bone microarchitecture in knee osteoarthritis using 3T MRI. AB - BACKGROUND: Osteoarthritis (OA) is now increasingly recognized as being related to the whole joint instead of the cartilage alone. In particular, the importance of subchondral bone in OA pathogenesis has drawn a lot of interest. The aim of this study is to investigate subchondral bone microstructural features in two femoral condyles of human knee osteoarthritis. METHODS: Eighty subjects were enrolled in our study and divided into three groups: without OA (group 0), mild OA (group 1), and severe OA (group 2). Sagittal 3D Balanced Fast Field Echo (3D FFE) images were obtained by 3T MRI to quantify trabecular bone structure, and sagittal FatSat 3D Fast Field Echo (3D-FFE) images were acquired to assess cartilage thickness. Trabecular bone parameters, including bone volume fraction (BVF), erosion index (EI) and the trabecular plate-to-rod ratio (SCR), and trabecular thickness were evaluated using digital topological analysis. Subchondral bone and cartilage parameters between different groups and different locations were compared, and their correlations were analyzed. RESULTS: Within two femoral condyles, subchondral bone structure was deteriorated in mild OA, showing a lower BVF (-0.011 to -0.014 P < 0.001), a higher EI (0.346 to 0.310 P < 0.001), a lower SCR (-0.581 to -0.542 P < 0.001)) and lower trabecular thickness (-6.588 to -4.759 P < 0.05). In severe OA, BVF was further decreased, but EI, SCR and trabecular thickness showed no significant difference than mild OA(P > 0.05). Moreover, there was a lower BVF, SCR and higher EI in the medial femoral condyle in each group. Interestingly, cartilage attrition mainly occurred in the medial femoral condyle. Medial cartilage thickness was not only positively correlated with the ipsilateral femoral BVF (r = 0.321 P = 0.004) but also with the opposite femoral BVF (r = 0.270 P = 0.015). CONCLUSIONS: Our results indicated that deterioration in the trabecular bone structure in both femoral condyles could more sensitively reveal early OA, and BVF could be a better biomarker to evaluate OA severity. PMID- 29179755 TI - Fever after bronchoscopy: serum procalcitonin enables early diagnosis of post interventional bacterial infection. AB - BACKGROUND: The aim of this study was to differentiate unspecific and self limiting fever after bronchoscopy from fever due to infection by using serum procalcitonin, C-reactive protein and neutrophil count. Furthermore, frequency of fever after bronchoscopy and procedures as possible risk factors were evaluated. METHODS: Three hundred and fourteen consecutive patients were included. All bronchoscopies were performed using jet-ventilation and general anesthesia. Patients were analyzed according to interventions performed during bronchoscopy and laboratory results. Microbiological assessment was done in patients who developed fever to prove or rule out a bacterial infection. RESULTS: Forty-four patients showed fever within 24 h following bronchoscopy (14%). A bacterial infection was proven in 11 patients with fever (3.5%). Procalcitonin, neutrophil count and C-reactive protein were significantly higher in patients with fever after bronchoscopy compared to non-fever patients. To predict bacterial infection in the receiver operating analysis, procalcitonin had the highest area under the curve (0.942; 95% confidence interval [CI], 0.768 to 1.000; p = <0.001), followed by neutrophil count (AUC, 0.804; 95% CI, 0.606 to 0.946; p = 0.005), whereas CRP levels where not statistically significant. Endoscopic airway recanalization was the only intervention that induced fever more frequently than all other interventions (OR 13.629). CONCLUSIONS: Fever is frequently seen after bronchoscopy and in some cases caused by bacterial infection. Procalcitonin might be useful to distinguish a bacterial infection from unspecific self-limiting fever. Airway recanalization is a procedure that seems to induce fever significantly more often than other bronchoscopic interventions. PMID- 29179756 TI - Causes and Three-year Incidence of Irreversible Visual Impairment in Jing-An District, Shanghai, China from 2010-2015. AB - BACKGROUND: The registry system can be used to observe the distribution trend of diseases and analyze the related data to provide useful information in a way that enables the government to take appropriate interventional measures. The purpose of this study was to determine the causes and three-year incidence of newly registered disabled patients who were blind or had low vision in Jing-An District, Shanghai, China from 2010 to 2015. METHODS: Data from the registration system of visual disability in Jing-An District, Shanghai from 2010 to 2015 were collected and analyzed. In this registry, the only person with permanent visual impairment (VI) was identified as being a certified visually impaired person. The main causes of visual disability were obtained, the three-year incidence of visual disability was calculated, and the relationships between blindness or low vision and age, as well as those between blindness or low vision and gender, were analyzed. RESULTS: Six-hundred and forty-six newly certified people with VI were registered, including 206 blind patients and 440 low vision patients. The major causes of blindness were myopia macular degeneration (MMD, 23.30%), glaucoma (20.39%), and age-related macular degeneration (AMD, 17.96%). The three leading causes of low vision were MMD (58.86%), AMD (16.36%), and diabetic retinopathy (DR, 7.27%). DR (16.0%) was the first leading cause of blindness and the second leading cause of VI in patients aged 30-59 yrs. from 2010 to 2015. The three-year incidences of blindness in 2010-2012 and 2013-2015(P = 0.43), which remained stable throughout this time period, were 32.74/100000 and 36.51/100000, respectively. However, the three-year incidence of low vision was 64.51/100000 in 2010-2012 and 83.58/100000 in 2013-2015(P = 0.007), which shows that the incidence increased significantly due to the increase of patients with low vision caused by MMD and DR (P = 0.003 and P = 0.01, respectively). CONCLUSIONS: MMD, glaucoma, and AMD were the main causes of blindness, while DR was becoming a major cause of VI, especially in working-age people of Jing-An District, Shanghai, China. PMID- 29179757 TI - Lockjaw from a metastatic uterine leiomyosarcoma- case report and review of the literature. AB - BACKGROUND: Leiomyosarcoma (LMS) is a malignant tumour formed of cells with distinct smooth muscle features. Leiomyosarcomas rarely metastasise to the oral cavity and this literature review details all reported cases of metastasis to the mandible found in the literature. This offers a unique perspective by specifying mandible as the site of metastasis of leiomyosarcoma. CASE PRESENTATION: A 53 year-old female presented to her General Practitioner (GP) with heavy menstrual bleeding and was diagnosed with multiple fibroids. Folowing a hysterectomy and removal of both tubes and ovaries for these symptomatic uterine fibroids, an incidental diagnosis of low grade leiomyosarcoma was made. A CT scan found no evidence of residual or metastatic disease and no further treatment was deemed necessary. 6 months later she presented to A & E with a numb lower lip but it took another 6 months for the diagnosis of metastatic LMS to the mandible to be made. DISCUSSION: Leiomyosarcomas are aggressive tumours which are liable to metastasise and therefore have a poor prognosis. An extensive literature review was undertaken to explore the frequency of metastasis in the maxillo-facial region. CONCLUSIONS: Although metastasis to the oral region is very rare as suggested from the literature review, when patients present with unusual symptoms after a diagnosis of LMS, physicians should be aware of the possibility of LMS metastases. PMID- 29179758 TI - Developmental performance of hospitalized severely acutely malnourished under-six children in low- income setting. AB - BACKGROUND: Retrospective studies show that severe acute malnutrition (SAM) affects child development. However, to what extent SAM affects children of different ages at its acute stage is not well documented. This study was aimed at comparing the developmental performance of severely acutely malnourished children under six with that of age and gender-matched non-malnourished healthy children. METHODS: The developmental performances of 310 children with SAM (male = 155, female = 155); mean age = 30.7 mo; SD = 15.2 mo) admitted to the nutritional rehabilitation unit (NRU) at Jimma University's Hospital was compared with that of 310 age and gender-matched, non-malnourished healthy children (male = 155, female = 155; mean age = 29.6 mo; SD = 15.4 mo) living in Jimma Town in Ethiopia. Two culturally adapted tools were used: (1) the Denver II-Jimma, to assess the children's performance on personal social (PS), fine motor (FM) language (LA), gross motor (GM) skills, and (2) the Ages and Stages Questionnaires: Social Emotional (ASQ:SE), to assess social-emotional (SE) skills. Multivariable Poisson regression analysis was conducted to compare the developmental performance scores of SAM and non-malnourished children. RESULTS: For one-year-old children, SAM delays their developmental performance on GM, FM, PS and LA by 300%, 200%, 140% and 71.4% respectively. For three-years-old children, SAM delays their developmental performance on GM by 80%, on FM and LA by 50% each, and on PS by 28.6%. Of the skills assessed on Denver II-Jimma, GM is the most, and PS is the least affected. Younger SAM children are more affected than older ones on all the domains of development. The delay in FM, GM, LA and PS generally decreases with an increase in age. Social-emotional behavior problems seem to be most pronounced in the very young and older age ranges. CONCLUSIONS: SAM has a differential age effect on the different dimensions of development in children under 6 years of age. PMID- 29179759 TI - Metabolic syndrome, diabetes and inadequate lifestyle in first-degree relatives of acute myocardial infarction survivors younger than 45 years old. AB - BACKGROUND: A premature myocardial infarction (PMI) is usually associated with a familial component. This study evaluated cardiovascular risk factors in first degree relatives (FDR) of patients with PMI not presenting the familial hypercholesterolemia phenotype. METHODS: A cross-sectional study comprising FDR of non-familial hypercholesterolemia patients who suffered a myocardial infarction <45-years age matched for age and sex with individuals without family history of cardiovascular disease. Subjects were evaluated for presence of the metabolic syndrome and its components, lifestyle, statin therapy, and laboratory parameters. RESULTS: The sample was composed of 166 FDR of 103 PMI patients and 111 controls. The prevalence of smoking (29.5 vs. 6.3%; p < 0.001), prediabetes (40.4 vs. 27%; p < 0.001), diabetes (19.9 vs. 1.8%; p < 0.001), metabolic syndrome (64.7 vs. 36%; p < 0.001), and dyslipidemia (84.2 vs. 31.2%; p = 0.001) was greater in FDR. There was no difference on the prevalence of abdominal obesity between groups. In addition, FDR presented higher triglycerides (179.0 +/ 71.0 vs. 140.0 +/- 74.0 mg/dL; p = 0.002), LDL-cholesterol (122.0 +/- 36.0 vs. 113.0 +/- 35 mg/dL; p = 0.031), non-HDL-cholesterol (157.0 +/- 53.0 vs. 141.0 +/- 41.0 mg/dL; p = 0.004), and lower HDL-cholesterol (39.0 +/- 10.0 vs. 48.0 +/- 14.0 mg/dL; p < 0.001) than controls. Thyrotropin levels (2.4 +/- 1.6 vs. 1.9 +/- 1.0 mUI/L; p = 0.002) were higher in FDR. The risk factor pattern was like the one of index cases. Only 5.9% (n = 10) of FDR were in use of statins. CONCLUSIONS: FDR of non-familial hypercholesterolemia patients with PMI presented an elevated prevalence of metabolic abnormalities, inadequate lifestyle and were undertreated for dyslipidemia. PMID- 29179760 TI - Exploring differences in stakeholders' perceptions of illegal bird trapping in Cyprus. AB - BACKGROUND: Cyprus is recognised as a hotspot for illegal bird trapping in the Mediterranean basin. A consumer demand for the Eurasian blackcap (Sylvia atricapilla) is driving the use of non-selective trapping methods, resulting in the indiscriminate killing of millions of migratory birds. Efforts to tackle the issue have so far been characterised mostly by a top-down approach, focusing on legislation and enforcement. However, trapping levels are not decreasing and conflict between stakeholder groups is intensifying. METHODS: To understand why efforts to stop illegal bird trapping have not been effective, we used semi structured interviews to interview 18 local bird trappers and nine representatives from the pertinent environmental non-governmental organisations (NGOs) and the governmental agencies responsible for enforcing the legislation. RESULTS: We found distinct differences between the views of the local trapping community and the environmental NGOs, particularly on why trapping is occurring and its impact on the avifauna. This disparity has contributed to misrepresentations of both sides and a high degree of conflict, which is potentially proving counterproductive to conservation interventions. In addition, it appears that trappers are a heterogeneous group, likely driven by various motivations besides profit. CONCLUSION: We argue that stakeholders interested in reducing illegal bird trapping need to develop anti-poaching strategies that aim at minimising the disparity in the views, and subsequently the conflict, acknowledging also that trappers are not a homogenous group, as often treated. PMID- 29179761 TI - Efficacy and safety of the "Xingnao Kaiqiao" acupuncture technique via intradermal needling to treat postoperative gastrointestinal dysfunction of laparoscopic surgery: study protocol for a randomized controlled trial. AB - BACKGROUND: Xingnao Kaiqiao acupuncture involves needling of the Neiguan (PC6), Renzhong (DU26), and Sanyinjiao (SP6) acupoints. The technique has a significant clinical effect in many neurological diseases. In the present report, we have developed a protocol for a scientific trial to analyze whether Xingnao Kaiqiao can be used to treat gastrointestinal dysfunction after laparoscopic surgery. In this context, we intend to execute a double-blind, randomized controlled trial to assess the efficacy and safety of Xingnao Kaiqiao acupuncture via intradermal needling. METHODS/DESIGN: This will be a single-center, double-blind, randomized controlled clinical trial. It has been designed on the basis of the Consolidated Standards of Reporting Trials (CONSORT 2010) guidelines and the Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA). The subjects will be recruited from among inpatients scheduled for laparoscopic surgery at the Department of Minimally Invasive Surgery, Tianjin Nankai Hospital, Tianjin, China. Using random numbers generated in SPSS 19.0, the recruited subjects will be allocated to either the "Xingnao Kaiqiao" group or the sham stimulation group. A specially appointed investigator will be in charge of the randomization. Xingnao Kaiqiao via intradermal needling (or sham needling) will be administered 6 h after laparoscopic surgery, and then every 12 h for a total of six sessions, each of which will last 3 min. The subjects will undergo their first evaluation shortly before the first treatment (6 h after laparoscopic surgery); evaluations will be repeated every 12 h until a total of seven evaluations have been completed. The primary outcome will be the time until the first postoperative flatus. The secondary outcomes will be: the time until the first postoperative defecation; levels of abdominal pain, abdominal distension, and nausea; blood ghrelin level; occurrence of vomiting; psychological status; and quality of life. DISCUSSION: This upcoming randomized clinical trial was designed as a standardized method to assess the efficacy and safety of Xingnao Kaiqiao acupuncture using intradermal needles on PC6, DU26, and SP6 in the treatment of gastrointestinal dysfunction after laparoscopic surgery. We aim to provide evidence and thus improve the clinical application of this technique. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ChiCTR-IOR-17010763 . Registered on 2 March 2017.

PMID- 29179763 TI - Whole transcriptome RNA-Seq analysis reveals extensive cell type-specific compartmentalization in Volvox carteri. AB - BACKGROUND: One of evolution's most important achievements is the development and radiation of multicellular organisms with different types of cells. Complex multicellularity has evolved several times in eukaryotes; yet, in most lineages, an investigation of its molecular background is considerably challenging since the transition occurred too far in the past and, in addition, these lineages evolved a large number of cell types. However, for volvocine green algae, such as Volvox carteri, multicellularity is a relatively recent innovation. Furthermore, V. carteri shows a complete division of labor between only two cell types - small, flagellated somatic cells and large, immotile reproductive cells. Thus, V. carteri provides a unique opportunity to study multicellularity and cellular differentiation at the molecular level. RESULTS: This study provides a whole transcriptome RNA-Seq analysis of separated cell types of the multicellular green alga V. carteri f. nagariensis to reveal cell type-specific components and functions. To this end, 246 million quality filtered reads were mapped to the genome and valid expression data were obtained for 93% of the 14,247 gene loci. In the subsequent search for protein domains with assigned molecular function, we identified 9435 previously classified domains in 44% of all gene loci. Furthermore, in 43% of all gene loci we identified 15,254 domains that are involved in biological processes. All identified domains were investigated regarding cell type-specific expression. Moreover, we provide further insight into the expression pattern of previously described gene families (e.g., pherophorin, extracellular matrix metalloprotease, and VARL families). Our results demonstrate an extensive compartmentalization of the transcriptome between cell types: More than half of all genes show a clear difference in expression between somatic and reproductive cells. CONCLUSIONS: This study constitutes the first transcriptome-wide RNA-Seq analysis of separated cell types of V. carteri focusing on gene expression. The high degree of differential expression indicates a strong differentiation of cell types despite the fact that V. carteri diverged relatively recently from its unicellular relatives. Our expression dataset and the bioinformatic analyses provide the opportunity to further investigate and understand the mechanisms of cell type-specific expression and its transcriptional regulation. PMID- 29179764 TI - Routine blood tests are associated with short term mortality and can improve emergency department triage: a cohort study of >12,000 patients. AB - BACKGROUND: Prioritization of acutely ill patients in the Emergency Department remains a challenge. We aimed to evaluate whether routine blood tests can predict mortality in unselected patients in an emergency department and to compare risk prediction with a formalized triage algorithm. METHODS: A prospective observational cohort study of 12,661 consecutive admissions to the Emergency Department of Nordsjaelland University Hospital during two separate periods in 2010 (primary cohort, n = 6279) and 2013 (validation cohort, n = 6383). Patients were triaged in five categories by a formalized triage algorithm. All patients with a full routine biochemical screening (albumin, creatinine, c-reactive protein, haemoglobin, lactate dehydrogenase, leukocyte count, potassium, and sodium) taken at triage were included. Information about vital status was collected from the Danish Central Office of Civil registration. Multiple logistic regressions were used to predict 30-day mortality. Validation was performed by applying the regression models on the 2013 validation cohort. RESULTS: Thirty-day mortality was 5.3%. The routine blood tests had a significantly stronger discriminative value on 30-day mortality compared to the formalized triage (AUC 88.1 [85.7;90.5] vs. 63.4 [59.1;67.5], p < 0.01). Risk stratification by routine blood tests was able to identify a larger number of low risk patients (n = 2100, 30-day mortality 0.1% [95% CI 0.0;0.3%]) compared to formalized triage (n = 1591, 2.8% [95% CI 2.0;3.6%]), p < 0.01. CONCLUSIONS: Routine blood tests were strongly associated with 30-day mortality in acutely ill patients and discriminatory ability was significantly higher than with a formalized triage algorithm. Thus routine blood tests allowed an improved risk stratification of patients presenting in an emergency department. PMID- 29179765 TI - Using peer advocates to improve access to services among hard-to-reach populations with hepatitis C: a qualitative study of client and provider relationships. AB - BACKGROUND: Peer support programmes use individuals with specific experiences to improve engagement and outcomes among new clients. However, the skills and techniques used to achieve this engagement have not been mapped. This potentially restricts the development and replication of successful peer advocate models of care. This study explored how a group of peer advocates with experience of homelessness, alcohol and drug misuse made and sustained relationships with their client group. For the purposes of this project, the client group were located among a hepatitis C-positive cohort of people who have a history of injecting drug use and homelessness. METHODS: Five self-selecting advocates gave a narrative interview lasting 40-90 min. These interviews were double transcribed using both thematic analysis and narrative analysis in order to triangulate the data and provide a robust set of findings about the unique skills of peer advocates in creating and sustaining relationships with clients from hard-to reach populations. RESULTS: Peer advocates build rapport with clients through disclosing personal details about their lives. While this runs counter to assumptions about the need to maintain distance in client-patient relationships, the therapeutic benefits appear to outweigh the potential costs of this engagement. CONCLUSION: We conclude the therapeutic benefits of self-disclosure between peer advocates and their clients offer a moral grounding for self disclosure as a means of building relationships with key hard-to-reach populations. PMID- 29179766 TI - Workload of horses on a water treadmill: effect of speed and water height on oxygen consumption and cardiorespiratory parameters. AB - BACKGROUND: Despite the use of water treadmills (WT) in conditioning horses, the intensity of WT exercise has not been well documented. The workload on a WT is a function of water height and treadmill speed. Therefore, the purpose of this study was to determine the effects of these factors on workload during WT exercise. Fifteen client-owned Quarter Horses were used in a randomized, controlled study. Three belt speeds and three water heights (mid cannon, carpus and stifle), along with the control condition (dry treadmill, all three speeds), were tested. Measured outcomes were oxygen consumption (VO2), ventilation (respiratory frequency, tidal volume (VT)), heart rate (HR), and blood lactate. An ergospirometry system was used to measure VO2 and ventilation. Linear mixed effects models were used to examine the effects of presence or absence of water, water height and speed (as fixed effects) on measured outcomes. RESULTS: Water height and its interaction with speed had a significant effect on VO2, VT and HR, all peaking at the highest water level and speed (stifle at 1.39 m/s, median VO2 = 16.70 ml/(kg.min), VT = 6 L, HR = 69 bpm). Respiratory frequency peaked with water at the carpus at 1.39 m/s (median 49 breaths/min). For a given water height, the small increments in speed did not affect the measured outcomes. Post exercise blood lactate concentration did not change. CONCLUSIONS: Varying water height and speed affects the workload associated with WT exercise. The conditions utilized in this study were associated with low intensity exercise. Water height had a greater impact on exercise intensity than speed.

PMID- 29179767 TI - Rhabdomyolysis, lactic acidosis, and multiple organ failure during telbivudine treatment for hepatitis B: a case report and review of the literature. AB - BACKGROUND: Telbivudine can cause severe side effects, including myositis, neuritis, rhabdomyolysis, and lactic acidosis. However, reported cases of telbivudine leading to multiple organ failure are rare. Here, we report a case of telbivudine-induced severe polymyositis, lactic acidosis, and multiple organ failure. CASE PRESENTATION: A 30-year-old Chinese man with hepatitis B virus infection received antiviral treatment with 600 mg of telbivudine daily for more than 11 months. He developed progressive weakness and myalgia, and subsequently experienced palpitations, chest tightness, lethargy, hypotension, and hypoxemia. Blood tests showed markedly elevated levels of alanine aminotransferase (955 U/L), aspartate aminotransferase (1375 U/L), blood urea nitrogen (14.9 mmol/L), creatine kinase (peak at 8050 U/L), and blood lactate (>20.0 mmol/L). His symptoms improved after continuous renal replacement therapy and short-term methylprednisolone treatment. Hyperbaric oxygen therapy, physical therapy, and rehabilitation for more than 2 months led to recovery of muscle strength to the normal range. CONCLUSIONS: We conclude that continuous renal replacement and steroid therapies play key roles in stabilizing telbivudine-induced severe rhabdomyolysis, lactic acidosis, and multiple organ failure. Hyperbaric oxygen, physical therapy, and rehabilitation may aid in functional recovery after the acute phase of lactic acidosis and organ failure. PMID- 29179769 TI - Catalogue of antibiotic resistome and host-tracking in drinking water deciphered by a large scale survey. AB - BACKGROUND: Excesses of antibiotic resistance genes (ARGs), which are regarded as emerging environmental pollutants, have been observed in various environments. The incidence of ARGs in drinking water causes potential risks to human health and receives more attention from the public. However, ARGs harbored in drinking water remain largely unexplored. In this study, we aimed at establishing an antibiotic resistome catalogue in drinking water samples from a wide range of regions and to explore the potential hosts of ARGs. RESULTS: A catalogue of antibiotic resistome in drinking water was established, and the host-tracking of ARGs was conducted through a large-scale survey using metagenomic approach. The drinking water samples were collected at the point of use in 25 cities in mainland China, Hong Kong, Macau, Taiwan, South Africa, Singapore and the USA. In total, 181 ARG subtypes belonging to 16 ARG types were detected with an abundance range of 2.8 * 10-2 to 4.2 * 10-1 copies of ARG per cell. The highest abundance was found in northern China (Henan Province). Bacitracin, multidrug, aminoglycoside, sulfonamide, and beta-lactam resistance genes were dominant in drinking water. Of the drinking water samples tested, 84% had a higher ARG abundance than typical environmental ecosystems of sediment and soil. Metagenomic assembly-based host-tracking analysis identified Acidovorax, Acinetobacter, Aeromonas, Methylobacterium, Methyloversatilis, Mycobacterium, Polaromonas, and Pseudomonas as the hosts of ARGs. Moreover, potential horizontal transfer of ARGs in drinking water systems was proposed by network and Procrustes analyses. CONCLUSIONS: The antibiotic resistome catalogue compiled using a large-scale survey provides a useful reference for future studies on the global surveillance and risk management of ARGs in drinking water. . PMID- 29179770 TI - Fertility outcomes following obstetric fistula repair: a prospective cohort study. AB - BACKGROUND: Obstetric fistula (OF) is a maternal morbidity associated with high rates of stillbirth, amenorrhea, and sexual dysfunction. Limited data exists on the reproductive outcomes of women in the years following a fistula repair. The objective of this study is to describe the fertility outcomes and family planning practices in a population of Malawian women 1-4 years after fistula repair. METHODS: Women who had enrolled into a clinical database of OF patients and undergone OF repair between January 1, 2012 and July 31, 2014 were recruited and enrolled to complete a home-based survey of their demographic and reproductive health data 1-4 years after their repair. Pregnancy, amenorrhea, and sexual function were described using frequency analysis, and we compared antimullerian hormone (AMH) concentrations between women with menses or pregnancy with women with amenorrhea or no pregnancy using Wilcoxon rank sum tests. RESULTS: Of 297 women with a prior OF repair, 148 had reproductive potential and were included in this analysis. Overall 30 women of these women (21%) became pregnant since their fistula repair, with most pregnancies ending with cesarean delivery. Of the 32 women who were amenorrheic at the time of repair, 25 (78.1%) had resumption of menses. Only 11 (8.6%) of sexually active women reported dyspareunia, and among women who were not trying to conceive, 53.1% were currently using a method of family planning. No significant differences were found in AMH concentrations between those who were pregnant or had menses versus those without pregnancy or menses, respectively. CONCLUSIONS: In this long-term follow-up study of women after OF repair, many women were able to achieve a pregnancy with a live birth, have normal menses, be sexually active, and access contraception. These achievements will further assist a population of women whose reintegration and restoration of dignity is closely tied to their ability to achieve their reproductive goals. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02685878 . PMID- 29179771 TI - Paracrine effects of human amniotic epithelial cells protect against chemotherapy induced ovarian damage. AB - BACKGROUND: Human amniotic epithelial cells (hAECs) are attractive candidates for regenerative medical therapy, with the potential to replace deficient cells and improve functional recovery after injury. Previous studies have demonstrated that transplantation of hAECs effectively alleviate chemotherapy-induced ovarian damage via inhibiting granulose cells apoptosis in animal models of premature ovarian failure/insufficiency (POF/POI). However, the underlying molecular mechanism accounting for hAECs-mediated ovarian function recovery is not fully understood. METHODS: To investigate whether hAECs-secreting cytokines act as molecular basis to attenuate chemotherapy-induced ovarian injury, hAECs or hAEC conditioned medium (hAEC-CM) was injected into the unilateral ovary of POF/POI mouse. Follicle development was evaluated by H&E staining at 1, 2 months after hAECs or hAEC-CM treatment. In addition, we performed a cytokine array containing 507 human cytokines on hAECs-derived serum-free conditioned medium. Finally, we further investigated whether hAECs could affect chemotherapy-induced apoptosis in primary human granulosa-lutein (hGL) cells and the tube formation of human umbilical vein endothelial cells (hUVECs) via a co-culture system in vitro. RESULTS: We observed the existence of healthy and mature follicles in ovaries treated with hAECs or hAEC-CM, whereas seriously fibrosis and many atretic follicles were found in the contralateral untreated ovaries of the same mouse. To distinguish cytokines involved in the process of hAECs-restored ovarian function, hAEC-CM was analyzed with a human cytokines array. Results revealed that 109 cytokines in hAEC-CM might participate in a variety of biological processes including apoptosis, angiogenesis, cell cycle and immune response. In vitro experiments, hAECs significantly inhibited chemotherapy-induced apoptosis and activated TGF-beta/Smad signaling pathway within primary granulosa-lutein cells in paracrine manner. Furthermore, hAEC-CM was shown to promote angiogenesis in the injured ovaries and enhance the tube formation of human umbilical vein endothelial cells (hUVECs) in co-culture system. CONCLUSIONS: These findings demonstrated that paracrine might be a key pathway in the process of hAECs mediating ovarian function recovery in animal models of premature ovarian failure/insufficiency (POF/POI). PMID- 29179773 TI - Sustained inflations versus UK standard inflations during initial resuscitation of prematurely born infants in the delivery room: a study protocol for a randomised controlled trial. AB - BACKGROUND: Many infants born at less than 34 weeks of gestational age will require resuscitation in the delivery suite. Yet, different resuscitation techniques are specified in different national guidelines, likely reflecting a limited evidence base. One difference is the length of mechanical inflation initially delivered to infants either via a facemask or endotracheal tube. Some guidelines specify short inflations delivered at rates of 40-60/min, others recommend initial inflations lasting 2-3 s or sustained inflations lasting for >= 5 s for initial resuscitation. Research has shown that tidal volumes > 2.2 mL/kg (the anatomical dead space) are seldom generated unless the infant's respiratory effort coincides with an inflation (active inflation). When inflations lasting 1 3 s were used, the time to the first active inflation was inversely proportional to the inflation time. This trial investigates whether a sustained inflation or repeated shorter inflations is more effective in stimulating the first active inflation. METHODS: This non-blinded, randomised controlled trial performed at a single tertiary neonatal unit is recruiting 40 infants born at < 34 weeks of gestational age. A 15-s sustained inflation is being compared to five repeated inflations of 2-3 s during the resuscitation at delivery. A respiratory function monitor is used to record airway pressure, flow, expiratory tidal volume and end tidal carbon dioxide (ETCO2) levels. The study is performed as emergency research without prior consent and was approved by the NHS London-Riverside Research Ethics Committee. The primary outcome is the minute volume in the first minute of resuscitation with secondary outcomes of the time to the first active inflation and ETCO2 level during the first minute of recorded resuscitation. DISCUSSION: This is the first study to compare a sustained inflation to the current UK practice of five initial inflations of 2-3 s. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02967562 .

AB - Next-generation sequencing (NGS) is now more accessible to clinicians and researchers. As a result, our understanding of the genetics of neurodevelopmental disorders (NDDs) has rapidly advanced over the past few years. NGS has led to the discovery of new NDD genes with an excess of recurrent de novo mutations (DNMs) when compared to controls. Development of large-scale databases of normal and disease variation has given rise to metrics exploring the relative tolerance of individual genes to human mutation. Genetic etiology and diagnosis rates have improved, which have led to the discovery of new pathways and tissue types relevant to NDDs. In this review, we highlight several key findings based on the discovery of recurrent DNMs ranging from copy number variants to point mutations. We explore biases and patterns of DNM enrichment and the role of mosaicism and secondary mutations in variable expressivity. We discuss the benefit of whole genome sequencing (WGS) over whole-exome sequencing (WES) to understand more complex, multifactorial cases of NDD and explain how this improved understanding aids diagnosis and management of these disorders. Comprehensive assessment of the DNM landscape across the genome using WGS and other technologies will lead to the development of novel functional and bioinformatics approaches to interpret DNMs and drive new insights into NDD biology. PMID- 29179774 TI - A 10-year surveillance of Rickettsiales (Rickettsia spp. and Anaplasma phagocytophilum) in the city of Hanover, Germany, reveals Rickettsia spp. as emerging pathogens in ticks. AB - BACKGROUND: Rickettsiales (Rickettsia spp. and Anaplasma phagocytophilum) transmitted by ticks are considered (re-)emerging pathogens posing a risk to public health. Nevertheless, year-long monitoring studies on prevalences of these pathogens in questing ticks to contribute to public health risk assessment are rare. METHODS: The current study extends previous prevalence surveillances (2005 and 2010) by 2015 to a 10-year monitoring. Therefore, 2100 questing Ixodes ricinus were collected from April to October 2015 at ten different recreation sites in the city of Hanover, Germany, to determine potential changes in tick infection rates with Rickettsiales. RESULTS: Of the collected ticks, 288 were adult females, 285 adult males and 1527 nymphs. Overall, 3.8% (79/2100) of ticks were infected with A. phagocytophilum, 50.8% (1066/2100) with Rickettsia spp. and 2.2% (46/2100) with both pathogens. Statistical analyses revealed stagnating A. phagocytophilum infection rates over the 10-year monitoring period, whereas Rickettsia infections increased significantly (33.3% in 2005 and 26.2% in 2010 vs 50.8% in 2015). This increase was also characterized by prominent seasonality with higher prevalences from July to October. CONCLUSIONS: As increased tick infection rates result in an increased risk for public health, the long-term data reported here provide significant implications for the understanding of progressing Rickettsiales distribution in ticks and essentially contribute to reliable public health risk assessments. PMID- 29179775 TI - Fusobacterium emphysematous pyomyositis with necrotizing fasciitis of the leg presenting as compartment syndrome: a case report. AB - BACKGROUND: Fusobacterium necrophorum is a common agent of disease in humans, but the occurrence of primary infections outside the head and neck area is extremely rare. While infection with Fusobacterium necrophorum has a rather benign course above the thorax, the organism is capable of producing very severe disease when located in unusual sites, including various forms of septic thrombophlebitis. No infections of the leg have been documented before; thus, antibiotic coverage for Fusobacterium is currently not recommended in this area. CASE PRESENTATION: A 50 year-old homeless African-American man presented complaining of severe pain in his right lower extremity. A clinical workup was consistent with emphysematous pyomyositis and compartment syndrome; he received limb-saving surgical intervention. The offending organism was identified as Fusobacterium necrophorum, and the antibiotic coverage was adjusted accordingly. CONCLUSIONS: Bacteria typically involved in necrotizing infections of the lower extremity include Group A beta-hemolytic Streptococcus, Clostridium perfringens, and common anaerobic bacteria (Bacteroides, Peptococcus, and Peptostreptococcus). This case report presents a case of gas gangrene of the leg caused by Fusobacterium necrophorum, the first such case reported. Fusobacterium should now be included in the differential diagnosis of necrotizing fasciitis of the extremities. PMID- 29179776 TI - Translation and cultural adaptation of the CLEFT-Q for use in Colombia, Chile, and Spain. AB - BACKGROUND: Cleft lip and/or palate (CL/P) is a common congenital craniofacial anomaly that may negatively affect an individual's appearance, health-related quality of life, or speech. In Spain, Colombia, and Chile the overall prevalence of CL/P ranges from 0.53 to 1.59 cases per 1000 live births. Currently, there is no patient-reported outcome (PRO) instrument that is specific for patients with CL/P. The CLEFT-Q is a new PRO instrument developed to measure outcomes of treatment in patients 8 to 29 years of age with CL/P. The aim of this study was to translate and culturally adapt the CLEFT-Q for use in Colombia, Chile, and Spain. METHODS: The CLEFT-Q was translated from English to 3 Spanish language varieties (Colombian, Chilean, and Spanish (Spain)) and Catalan. Translation and cultural adaptation guidelines set forth by the International Society for Pharmacoeconomics and Outcomes Research were followed. RESULTS: The field- test version of the CLEFT-Q consisted of 13 scales (total 154 items) measuring appearance, health-related quality of life, and facial function. Forward translations revealed 10 (7%) items that were difficult to translate into Chilean, and back translations identified 34 (22%) and 21 (13%) items whose meaning differed from the English version in at least 1 of the 3 Spanish varieties and Catalan respectively. Twenty-one participants took part in cognitive debriefing interviews. Participants were recruited from plastic surgery centres in Bogota, Colombia (n = 4), Santiago, Chile (n = 7), and Barcelona, Spain (n = 10). Most participants were males (n = 14, 67%) and were diagnosed with CL/P (n = 17, 81%). Participants reported difficulty understanding 1 item in the Colombian, 1 item in the Spanish (Spain), and 11 items from the Catalan version. Comparison of the 3 Spanish varieties revealed 61 (40%) of the 154 items whose wording differed across the 3 Spanish versions. CONCLUSION: Translation and cultural adaptation processes provided evidence of transferability of the CLEFT-Q scales into 3 Spanish varieties and Catalan, as semantic, idiomatic, experiential, and conceptual equivalence of the items, instructions, and response options were achieved. PMID- 29179777 TI - A document-centric approach for developing the tolAPC ontology. AB - BACKGROUND: There are many challenges associated with ontology building, as the process often touches on many different subject areas; it needs knowledge of the problem domain, an understanding of the ontology formalism, software in use and, sometimes, an understanding of the philosophical background. In practice, it is very rare that an ontology can be completed by a single person, as they are unlikely to combine all of these skills. So people with these skills must collaborate. One solution to this is to use face-to-face meetings, but these can be expensive and time-consuming for teams that are not co-located. Remote collaboration is possible, of course, but one difficulty here is that domain specialists use a wide-variety of different "formalisms" to represent and share their data - by the far most common, however, is the "office file" either in the form of a word-processor document or a spreadsheet. Here we describe the development of an ontology of immunological cell types; this was initially developed by domain specialists using an Excel spreadsheet for collaboration. We have transformed this spreadsheet into an ontology using highly-programmatic and pattern-driven ontology development. Critically, the spreadsheet remains part of the source for the ontology; the domain specialists are free to update it, and changes will percolate to the end ontology. RESULTS: We have developed a new ontology describing immunological cell lines built by instantiating ontology design patterns written programmatically, using values from a spreadsheet catalogue. CONCLUSIONS: This method employs a spreadsheet that was developed by domain experts. The spreadsheet is unconstrained in its usage and can be freely updated resulting in a new ontology. This provides a general methodology for ontology development using data generated by domain specialists. PMID- 29179778 TI - Determining requirements for patient-centred care: a participatory concept mapping study. AB - BACKGROUND: Recognition of a need for patient-centred care is not new, however making patient-centred care a reality remains a challenge to organisations. We need empirical studies to extend current understandings, create new representations of the complexity of patient-centred care, and guide collective action toward patient-centred health care. To achieve these ends, the research aim was to empirically determine what organisational actions are required for patient-centred care to be achieved. METHODS: We used an established participatory concept mapping methodology. Cross-sector stakeholders contributed to the development of statements for patient-centred care requirements, sorting statements into groupings according to similarity, and rating each statement according to importance, feasibility, and achievement. The resultant data were analysed to produce a visual concept map representing participants' conceptualisation of patient-centred care requirements. Analysis included the development of a similarity matrix, multidimensional scaling, hierarchical cluster analysis, selection of the number of clusters and their labels, identifying overarching domains and quantitative representation of rating data. RESULTS: The outcome was the development of a conceptual map for the Requirements of Patient-Centred Care Systems (ROPCCS). ROPCCS incorporates 123 statements sorted into 13 clusters. Cluster labels were: shared responsibility for personalised health literacy; patient provider dynamic for care partnership; collaboration; shared power and responsibility; resources for coordination of care; recognition of humanity - skills and attributes; knowing and valuing the patient; relationship building; system review evaluation and new models; commitment to supportive structures and processes; elements to facilitate change; professional identity and capability development; and explicit education and learning. The clusters were grouped into three overarching domains, representing a cross-sectoral approach: humanity and partnership; career spanning education and training; and health systems, policy and management. Rating of statements allowed the generation of go-zone maps for further interrogation of the relative importance, feasibility, and achievement of each patient-centred care requirement and cluster. CONCLUSION: The study has empirically determined requirements for patient-centred care through the development of ROPCCS. The unique map emphasises collaborative responsibility of stakeholders to ensure that patient-centred care is comprehensively progressed. ROPCCS allows the complex requirements for patient centred care to be understood, implemented, evaluated, measured, and shown to be occurring. PMID- 29179779 TI - Evaluation of in silico algorithms for use with ACMG/AMP clinical variant interpretation guidelines. AB - BACKGROUND: The American College of Medical Genetics and American College of Pathologists (ACMG/AMP) variant classification guidelines for clinical reporting are widely used in diagnostic laboratories for variant interpretation. The ACMG/AMP guidelines recommend complete concordance of predictions among all in silico algorithms used without specifying the number or types of algorithms. The subjective nature of this recommendation contributes to discordance of variant classification among clinical laboratories and prevents definitive classification of variants. RESULTS: Using 14,819 benign or pathogenic missense variants from the ClinVar database, we compared performance of 25 algorithms across datasets differing in distinct biological and technical variables. There was wide variability in concordance among different combinations of algorithms with particularly low concordance for benign variants. We also identify a previously unreported source of error in variant interpretation (false concordance) where concordant in silico predictions are opposite to the evidence provided by other sources. We identified recently developed algorithms with high predictive power and robust to variables such as disease mechanism, gene constraint, and mode of inheritance, although poorer performing algorithms are more frequently used based on review of the clinical genetics literature (2011-2017). CONCLUSIONS: Our analyses identify algorithms with high performance characteristics independent of underlying disease mechanisms. We describe combinations of algorithms with increased concordance that should improve in silico algorithm usage during assessment of clinically relevant variants using the ACMG/AMP guidelines. PMID- 29179780 TI - A highly transmissible tuberculosis outbreak: the importance of bars. AB - The transmission of tuberculosis (TB) in bars is difficult to study. The objective was to describe a large TB outbreak in a company's bar and other leisure settings. A descriptive study of a TB outbreak was carried out. Contacts were studied in the index case's workplace bar (five circles of contacts) and other recreational areas (social network of three bars in the index case's neighbourhood). Chest X-rays were recommended to contacts with positive tuberculin skin tests (TST) (?5 mm). The risk of latent tuberculosis infection (LTBI) was determined using an adjusted odds ratio. The dose-response relationship was determined using the chi-square test for linear trend. We studied 316 contacts at the index case's workplace and detected five new cases of TB. The prevalence of LTBI was 57.9% (183/316) and was higher in the first circle, 96.0% (24/25), and lower in the fifth, 46.5% (20/43) (P < 0.0001). Among 58 contacts in the three neighbourhood bars, two TB cases were detected and the LTBI prevalence was 51.7% (30/58). Two children of one secondary TB company patient became ill. Bars may be transmission locations for TB and, as they are popular venues for social events, should be considered as potential areas of exposure.

PMID- 29179781 TI - Low-fat yogurt consumption reduces biomarkers of chronic inflammation and inhibits markers of endotoxin exposure in healthy premenopausal women: a randomised controlled trial. AB - The anti-inflammatory mechanisms of low-fat dairy product consumption are largely unknown. The objective of this study was to determine whether low-fat yogurt reduces biomarkers of chronic inflammation and endotoxin exposure in women. Premenopausal women (BMI 18.5-27 and 30-40 kg/m2) were randomised to consume 339 g of low-fat yogurt (yogurt non-obese (YN); yogurt obese (YO)) or 324 g of soya pudding (control non-obese; control obese (CO)) daily for 9 weeks (n 30/group). Fasting blood samples were analysed for IL-6, TNF-alpha/soluble TNF II (sTNF RII), high-sensitivity C-reactive protein, 2-arachidonoyl glycerol, anandamide, monocyte gene expression, soluble CD14 (sCD14), lipopolysaccharide (LPS), LPS binding protein (LBP), IgM endotoxin-core antibody (IgM EndoCAb), and zonulin. BMI, waist circumference and blood pressure were also determined. After 9-week yogurt consumption, YO and YN had decreased TNF-alpha/sTNFR-RII. Yogurt consumption increased plasma IgM EndoCAb regardless of obesity status. sCD14 was not affected by diet, but LBP/sCD14 was lowered by yogurt consumption in both YN and YO. Yogurt intervention increased plasma 2-arachidonoylglycerol in YO but not YN. YO peripheral blood mononuclear cells expression of NF-kappaB inhibitor alpha and transforming growth factor beta1 increased relative to CO at 9 weeks. Other biomarkers were unchanged by diet. CO and YO gained approximately 0.9 kg in body weight. YO had 3.6 % lower diastolic blood pressure at week 3. Low-fat yogurt for 9 weeks reduced biomarkers of chronic inflammation and endotoxin exposure in premenopausal women compared with a non-dairy control food. This trial was registered as NCT01686204.

AB - A "stone in the pond" strategy is a practical approach to investigating large scale nosocomial tuberculosis (TB) exposures. Here, we describe such a risk stratified approach to contact tracing after a TB exposure that occurred over 5 months in a pediatric inpatient ward in a country with a moderate TB burden. Infect Control Hosp Epidemiol 2017;38:1509-1511. PMID- 29179784 TI - Underweight increases the risk of early death in tuberculosis patients. AB - Evidence regarding the association between BMI and mortality in tuberculosis (TB) patients is limited and inconsistent. We investigated the impact of BMI on TB specific and non-TB-specific mortality with respect to different timing of death. All Taiwanese adults with TB in Taipei were included in a retrospective cohort study in 2012-2014. Multinomial Cox proportional hazards regression was used to evaluate the associations between BMI, cause-specific mortality and timing of death. Of 2410 eligible patients, 86.0 % (2061) were successfully treated, and TB specific and non-TB-specific mortality occurred for 2.2 % (54) and 13.9 % (335), respectively. After controlling for potential confounders, underweight was significantly associated with a higher risk of all-cause mortality (adjusted hazard ratio (AHR) 1.57; 95 % CI 1.26, 1.95), whereas overweight was not. When cause-specific death was considered, underweight was associated with an increased risk of either TB-specific (AHR 1.85; 95 % CI 1.03, 3.33) or non-TB-specific death (AHR 1.52; 95 % CI 1.19, 1.95) during treatment. With joint consideration of cause-specific and timing of death, underweight only significantly increased the risk of TB-specific (AHR 2.23; 95 % CI 1.09, 4.59) and non-TB-specific mortality (AHR 1.81; 95 % CI 1.29, 2.55) within the first 8 weeks of treatment. This study suggests that underweight increases the risk of early death in TB patients during treatment. PMID- 29179785 TI - Toxoplasma gondii reorganizes the host cell architecture during spontaneous cyst formation in vitro. AB - Toxoplasma gondii is an intracellular protozoan parasite that causes toxoplasmosis, a prevalent infection related to abortion, ocular diseases and encephalitis in immuno-compromised individuals. In the untreatable (and life long) chronic stage of toxoplasmosis, parasitophorous vacuoles (PVs, containing T. gondii tachyzoites) transform into tissue cysts, containing slow-dividing bradyzoite forms. While acute-stage infection with tachyzoites involves global rearrangement of the host cell cytoplasm, focused on favouring tachyzoite replication, the cytoplasmic architecture of cells infected with cysts had not been described. Here, we characterized (by fluorescence and electron microscopy) the redistribution of host cell structures around T. gondii cysts, using a T. gondii strain (EGS) with high rates of spontaneous cystogenesis in vitro. Microtubules and intermediate filaments (but not actin microfilaments) formed a 'cage' around the cyst, and treatment with taxol (to inhibit microtubule dynamics) favoured cystogenesis. Mitochondria, which appeared adhered to the PV membrane, were less closely associated with the cyst wall. Endoplasmic reticulum (ER) profiles were intimately associated with folds in the cyst wall membrane. However, the Golgi complex was not preferentially localized relative to the cyst, and treatment with tunicamycin or brefeldin A (to disrupt Golgi or ER function, respectively) had no significant effect on cystogenesis. Lysosomes accumulated around cysts, while early and late endosomes were more evenly distributed in the cytoplasm. The endocytosis tracer HRP (but not BSA or transferrin) reached bradyzoites after uptake by infected host cells. These results suggest that T. gondii cysts reorganize the host cell cytoplasm, which may fulfil specific requirements of the chronic stage of infection. PMID- 29179786 TI - A chemical compound based on methylxanthine-polyphenols lowers nitric oxide levels and increases post-thaw human sperm viability. AB - We produced a new chemical compound based on methylxanthines and polyphenols (CCMP) present in the chemical matrix of guarana (Paullinia cupana), a seed extract with antioxidant properties. After supplementation with the standard extract of resveratrol, a well documented antioxidant found in other plant sources, we investigated whether this resveratrol-enriched compound could improve sperm viability and modulate differentially reactive oxygen species (ROS) and nitric oxide (NO) levels in thawed sperm. Sperm samples obtained from healthy young donors were treated with different concentrations of guarana extract (0.1, 1, 5 or 10 mg/ml) and cells were frozen at -80 degrees C for 24 h. In addition, the potential protective effects of guarana treatment on sperm treated with pro oxidant compound (200 uM hydrogen peroxide, H2O2) were assessed. Samples were also exposed to three concentrations of CCMP before being frozen in liquid nitrogen (-196 degrees C) or in an ultrafreezer (-80 degrees C) for 24 h, and both pre-freezing and post-thaw measurements of viability and oxidative stress were performed. Guarana supplementation at 10 mg/ml significantly increased post thaw viability and decreased oxidative metabolism of the sperm. Moreover, selected concentrations of CCMP improved viability and oxidative metabolism in sperm samples pre-freezing. Furthermore, CCMP showed cryoprotective activity by increasing viability and decreasing oxidative stress in post-thaw samples. In summary, these findings suggested that CCMP supplementation acts as a cryoprotectant to modulate ROS and NO levels in thawed sperm. CCMP could be used to enhance sperm quality and reproductive success. PMID- 29179787 TI - Sperm-derived factors enhance the in vitro developmental potential of haploid parthenotes. AB - Parthenotes are characterized by poor in vitro developmental potential either due to the ploidy status or the absence of paternal factors. In the present study, we demonstrate the beneficial role of sperm-derived factors (SDF) on the in vitro development of mouse parthenotes. Mature (MII) oocytes collected from superovulated Swiss albino mice were activated using strontium chloride (SrCl2) in the presence or absence of various concentrations of SDF in M16 medium. The presence of SDF in activation medium did not have any significant influence on the activation rate. However, a significant increase in the developmental potential of the embryos and increased blastocyst rate (P < 0.01) was observed at 50 ug/ml concentration. Furthermore, the activated oocytes from this group exhibited early cleavage and cortical distribution of cortical granules that was similar to that of normally fertilized zygotes. Culturing 2-cell stage parthenotes in the presence of SDF significantly improved the developmental potential (P < 0.05) indicating that they also play a significant role in embryo development. In conclusion, artificial activation of oocytes with SDF can improve the developmental potential of parthenotes in vitro. PMID- 29179789 TI - A case of mistaken identity? - CORRIGENDUM. PMID- 29179788 TI - X-ray micro-computed tomography (MUCT): an emerging opportunity in parasite imaging. AB - X-ray micro-computed tomography (MUCT) is a technique which can obtain three dimensional images of a sample, including its internal structure, without the need for destructive sectioning. Here, we review the capability of the technique and examine its potential to provide novel insights into the lifestyles of parasites embedded within host tissue. The current capabilities and limitations of the technology in producing contrast in soft tissues are discussed, as well as the potential solutions for parasitologists looking to apply this technique. We present example images of the mouse whipworm Trichuris muris and discuss the application of MUCT to provide unique insights into parasite behaviour and pathology, which are inaccessible to other imaging modalities. PMID- 29179790 TI - Mobile phone usage does not affect sudden sensorineural hearing loss. AB - OBJECTIVE: Recent studies found that mobile phone users had a significantly greater risk of having elevated thresholds in speech frequencies. This study investigated the correlation between the laterality of sudden sensorineural hearing loss, handedness and the preferred ear for mobile phone use. METHODS: The study included all patients who presented with sudden sensorineural hearing loss to the Department of Otolaryngology - Head and Neck Surgery in our tertiary referral medical centre between 2014 and 2016. Patients were asked to indicate their dominant hand and preferred ear for mobile phone use. RESULTS: The study comprised 160 patients. No correlation was found between the dominant hand or preferred ear for mobile phone use and the side of sudden sensorineural hearing loss. There was no correlation between the side of the sudden sensorineural hearing loss (preferable or non-preferable for mobile phone use) and audiometric characteristics. CONCLUSION: No correlation was found between the laterality of ears used for mobile phone and sudden sensorineural hearing loss. PMID- 29179791 TI - Influence of parasite load on the diagnosis and occurrence of eosinophilia in alcoholic patients infected with Strongyloides stercoralis. AB - Alcoholic patients are more susceptible to Strongyloides stercoralis infection. The chronic use of alcohol raises the levels of endogenous corticosteroids, which regulates the development of larvae and stimulates the differentiation of rhabditiform into infective filariform larvae, thus inducing internal autoinfection. Therefore, early diagnosis is important to prevent severe strongyloidiasis. The aim of this study was to evaluate the efficacy of parasitological methods, according to the parasite load and the number of stool samples, for diagnosis of S. stercoralis infection, as well the peripheral blood eosinophil count in alcoholic patients. A total of 330 patients were included in this study. The diagnosis was established using three parasitological methods: agar plate culture, Baermann-Moraes method and spontaneous sedimentation. Peripheral eosinophilia was considered when the level was >600 eosinophils/mm3. The agar plate culture (APC) had the highest sensitivity (97.3%). However, the analysis of multiple samples increased the sensitivity of all parasitological methods. The sensitivities of the methods were influenced by the parasite load. When the larval number was above 10, the sensitivity of APC was 100%, while in spontaneous sedimentation the sensitivity reached 100% when the larval number was above 50. In the present study, 15.4% of alcoholic patients infected with S. stercoralis (12/78) had increased peripheral blood eosinophil count (above 600 eosinophils/mm3). For an efficient parasitological diagnosis of S. stercoralis infection in alcoholic patients, repeated examination by two parasitological methods must be recommended, including agar plate culture due to its higher sensitivity. Moreover, S. stercoralis infection was associated with eosinophilia, mostly in patients excreting up to 10 larvae/g faeces. PMID- 29179793 TI - Science news. PMID- 29179795 TI - Events diary.

PMID- 29179799 TI - Additives, Hole Transporting Materials and Spectroscopic Methods to Characterize the Properties of Perovskite Films. AB - The achievement of high efficiency and high stability in perovskite solar cells (PSCs) requires optimal selection and evaluation of the various components. After a brief introduction to the perovskite materials and their historical evolution, the first part is devoted to the hole transporting material (HTM), between photoelectrode and dark counter electrode. The basic requirements for an efficient HTM are stated. Subsequently, the most used HTM, spiro-OMeTAD, is compared to alternative HTMs, both small-molecule size species and electronically conducting polymers. The second part is devoted to additives related to the performance of the perovskite light-absorbing material itself. These are related either to the modification of the composition of the material itself or to the optimization of the morphology during the perovskite preparation stage, and their effect is in the enhancement of the power conversion efficiency, the long-term stability, or the reproducibility of the properties of the PSCs. Finally, a number of spectroscopic methods based on the UV-Vis part of the electromagnetic spectrum useful for characterizing the different perovskite material types are described in the last part of this review.

AB - A series of neutral alpha-diimine ligands with diacetyl and acenaphthenequinone skeletons were prepared by the reaction between diacetyl and the corresponding aromatic amine. These ligands reacted with ZnCl2 to generate symmetric alpha diimine zinc complexes C1-C10. Experimental results indicated that the alpha diimine zinc complexes with a diacetyl skeleton (C1-C4) were active in ring opening polymerization (ROP) of epsilon-caprolactone (epsilon-CL). The complexes with an acenaphthenequinone skeleton showed a small steric effect (C5, C8 and C9) but the complex substituted with an electron-withdrawing group (C10) showed high activity in the monomer conversion rate during ROP of epsilon-CL. The ROP catalysts of epsilon-CL demonstrated the mechanism of monomer activation in the presence of benzyl alcohol. PMID- 29179806 TI - Summer School 2017 - Exchange of Ideas for Biologists.

PMID- 29179808 TI - Ultrasound-Assisted Extraction of Anthocyanins from Red Rose Petals and New Spectrophotometric Methods for the Determination of Total Monomeric Anthocyanins. AB - In this study, four extraction technologies for the extraction of anthocyanins (Acyns) from red rose petals (RRPs) were investigated and compared, including ultrasound-assisted extraction (UAE), reflux extraction, Soxhlet extraction, and marinated extraction. UAE was the most suitable for the extraction of Acyns from RRPs because of its high extraction efficiency and short extraction time. The results showed that the best conditions for UAE are an extraction solution of ethanol-0.1 N HCl (80 + 20, v/v), a solid-to-liquid ratio of 1:40 g/mL, a temperature of 30 degrees C, and an extraction time of 15 min performed three times. Using such conditions, 320.4 mg Acyns/100 g RRPs was extracted. UAE was followed by two new difference spectrophotometric (DS) methods, which were developed for the fast and simple determination of Acyns in RRPs. Under the optimum experimental conditions, a linear response was observed for Acyns in the range of 12.5-62.5 MUg/mL for the two proposed methods, with correlation coefficients (r) ranging from 0.9988 to 0.9995. The mean recovery values of Acyns for the DS methods were in the range of 99.8-101.5%, and the RSD was 0.5%. The respective LOD and the LOQ values were 1.4 and 4.8 for DS1 and 1.1 and 3.6 MUg/mL for DS2. The stability of Acyns was also studied. PMID- 29179809 TI - Factors that affect general practice as a choice of medical speciality: implications for policy development. AB - Objective This article critically appraises the range of personal, professional and social factors that affect the choice of speciality across medical students, prevocational doctors, general practice registrars and general practitioners.Methods This qualitative study applied constructs from the fields of decision theory and career theory to better understand the complex nature of choosing a speciality. In all, 47 in-depth interviews were conducted with participants at different stages of their career cycle. The data was codified and analysed using NVivo to identify key factors that influenced speciality choice.Results The research identified 77 individual findings influencing general practice as a choice of medical speciality. These were distilled into a matrix to show that factors such as money, prestige and peer interaction did not have a compelling effect, whereas clinical and academic role models, flexibility, work life balance, scope of practice, connection with patients, training environment and practical opportunities did.Conclusion The findings indicate that the decision in relation to the choice of medical speciality is a complex cognitive process that is undertaken within a personal, social and professional context particular to each individual.What is known about the topic? Current literature aims to quantify changes in attitudes towards choice of speciality or the effect of particular variables in isolation while ignoring the complexity of this decision process and how the numerous variables compare with each other.What does this paper add? The present study is the first intergenerational research on this topic in the Australian context and the paper dismisses the role of prestige and remuneration as key drivers of choice in picking general practice as a speciality, noting that money is merely a 'hygiene factor'.What are the implications for policy makers? A policy framework outlining 10 key principles is presented to assist policy makers seeking to affect workforce outcomes by applying policy levers to influence doctors' choice of speciality. PMID- 29179810 TI - De novo transcription of thyroid hormone receptors is essential for early bovine embryo development in vitro. AB - Thyroid hormone receptor (THR) alpha and THRbeta mediate the genomic action of thyroid hormones (THs) that affect bovine embryo development. However, little is known about THRs in the preimplantation embryo. The aim of the present study was to investigate the importance of THRs in in vitro preimplantation bovine embryos. THR transcripts and protein levels were detected in developing preimplantation embryos up to the blastocyst stage. Embryonic transcription of THRs was inhibited by alpha-amanitin supplementation, and both maternal and embryonic transcription were knocked down by short interference (si) RNA microinjection. In the control group, mRNA and protein levels of THRs increased after fertilisation. In contrast, in both the transcription inhibition and knockdown groups there were significant (P<0.05) decreases in mRNA expression of THRs from the 2-cell stage onwards. However, protein levels of THRs were not altered at 2-cell stage, although they did exhibit a significant (P<0.05) decrease from the 4-cell stage. Moreover, inhibition of de novo transcripts of THRs using siRNA led to a significant (P<0.01) decrease in the developmental rate and cell number, as well as inducing a change in embryo morphology. In conclusion, THRs are transcribed soon after fertilisation, before major activation of the embryonic genome, and they are essential for bovine embryo development in vitro. PMID- 29179811 TI - Economic modelling of telehealth substitution of face-to-face specialist outpatient consultations for Queensland correctional facilities. AB - Objective The provision of healthcare services to inmates in correctional facilities is costly and resource-intensive. This study aimed to estimate the costs of transporting prisoners from 11 Queensland correctional facilities to the Princess Alexandra Hospital Secure Unit (PAHSU) in Brisbane for non-urgent specialist outpatient consultations and identify the cost consequences that would result from the substitution of face-to-face visits with telehealth consultations.Methods A 12-month retrospective review of patient activity at the PAHSU was conducted to obtain the number of transfers per correctional facility. The total cost of transfers was calculated with estimates for transport vehicle costs and correctional staff escort wages, per diem and accommodation costs. A cost model was developed to estimate the potential cost savings from substituting face-to-face consultations with telehealth consultations. A sensitivity analysis on the cost variables was conducted. Costs are reported from a government funding perspective and presented in 2016 Australian dollars (A$).Results There were 3539 inmate appointments from July 2015 to June 2016 at the PAHSU, primarily for imaging, general practice, and orthopaedics. Telehealth may result in cost savings from negligible to A$969731, depending on the proportion, and travel distance, of face-to-face consultations substituted by telehealth. Wages of correctional staff were found to be the most sensitive variable.Conclusions Under the modelled conditions, telehealth may reduce the cost of providing specialist outpatient consultations to prisoners in Queensland correctional facilities. Telehealth may improve the timeliness of services to a traditionally underserved population.What is known about the topic? Specialist medical services are located in only a few metropolitan centres across Australia, which requires some populations to travel long distances to attend appointments. Some face-to-face specialist outpatient consultations can be substituted by telehealth.What does this paper add? Prisoners from correctional facilities represent one specific population that requires complex travel arrangements for specialist medical appointments. Transportation of prisoners for specialist health appointments represents a substantial cost to the government. This paper quantifies the annual cost in Queensland for transporting prisoners, taking into account fuel and vehicle costs, staff wages, per diem rates, and accommodation. In addition, it quantifies the costs of substituting face-to-face consultations with telehealth consultations.What are the implications for practitioners? This research encourages practitioners to consider using telehealth services for prisoners, as well providing an argument for tertiary centres to include telehealth as a model of care for this population. Telehealth can result in major cost savings and state and federal governments should consider implementation especially in Australia where correctional facilities and specialist services are separated by great geographic distances.

AB - How left-right patterning drives asymmetric morphogenesis is unclear. Here, we have quantified shape changes during mouse heart looping, from 3D reconstructions by HREM. In combination with cell labelling and computer simulations, we propose a novel model of heart looping. Buckling, when the cardiac tube grows between fixed poles, is modulated by the progressive breakdown of the dorsal mesocardium. We have identified sequential left-right asymmetries at the poles, which bias the buckling in opposite directions, thus leading to a helical shape. Our predictive model is useful to explore the parameter space generating shape variations. The role of the dorsal mesocardium was validated in Shh-/- mutants, which recapitulate heart shape changes expected from a persistent dorsal mesocardium. Our computer and quantitative tools provide novel insight into the mechanism of heart looping and the contribution of different factors, beyond the simple description of looping direction. This is relevant to congenital heart defects. PMID- 29179814 TI - The effect of perinatal brain injury on dopaminergic function and hippocampal volume in adult life. AB - Perinatal brain injuries, including hippocampal lesions, cause lasting changes in dopamine function in rodents, but it is not known if this occurs in humans. We compared adults who were born very preterm with perinatal brain injury to those born very preterm without perinatal brain injury, and age-matched controls born at full term using [18F]-DOPA PET and structural MRI. Dopamine synthesis capacity was reduced in the perinatal brain injury group relative to those without brain injury (Cohen's d = 1.36, p=0.02) and the control group (Cohen's d = 1.07, p=0.01). Hippocampal volume was reduced in the perinatal brain injury group relative to controls (Cohen's d = 1.17, p=0.01) and was positively correlated with striatal dopamine synthesis capacity (r = 0.344, p=0.03). This is the first evidence in humans linking neonatal hippocampal injury to adult dopamine dysfunction, and provides a potential mechanism linking early life risk factors to adult mental illness. PMID- 29179817 TI - A Concept Analysis of Substance Misuse to Inform Contemporary Terminology. AB - Previous diagnostic categories of substance abuse and dependence have given way to the current view that substance use disorders occur on a continuum with a broad range of severity. This current view is featured in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM V). In recognizing the role of stigma in preventing persons from seeking substance use treatment, advocates have called attention that particular terminology can fuel such stigma. To mitigate the negative effects of such stigmatizing language, the International Society of Addiction Journal Editors (ISAJE) recommends against using previously used and possibly pejorative terminology for substance abuse and dependence, unless a particular scientific justification exists. The purpose of this paper is to: (1) present a concept analysis of the term substance misuse and (2) recommend an alternate term for substance misuse that is neither pejorative nor inadvertently stigmatizing: at-risk substance use. PMID- 29179815 TI - CHARGE syndrome modeling using patient-iPSCs reveals defective migration of neural crest cells harboring CHD7 mutations. AB - CHARGE syndrome is caused by heterozygous mutations in the chromatin remodeler, CHD7, and is characterized by a set of malformations that, on clinical grounds, were historically postulated to arise from defects in neural crest formation during embryogenesis. To better delineate neural crest defects in CHARGE syndrome, we generated induced pluripotent stem cells (iPSCs) from two patients with typical syndrome manifestations, and characterized neural crest cells differentiated in vitro from these iPSCs (iPSC-NCCs). We found that expression of genes associated with cell migration was altered in CHARGE iPSC-NCCs compared to control iPSC-NCCs. Consistently, CHARGE iPSC-NCCs showed defective delamination, migration and motility in vitro, and their transplantation in ovo revealed overall defective migratory activity in the chick embryo. These results support the historical inference that CHARGE syndrome patients exhibit defects in neural crest migration, and provide the first successful application of patient-derived iPSCs in modeling craniofacial disorders. PMID- 29179818 TI - The Effect of the Cognitive-behavioral Model-based Psychoeducation and Exercise Intervention on Quality of Life in Alcohol Use Disorder. AB - PURPOSE: The aim of the study was to assess the effect of the cognitive behavior model (CBM)-based psychoeducation and exercise intervention on quality of life (QoL) in alcohol use disorder (AUD). DESIGN: This study was a non-randomized controlled trial. METHODS: CBM-based psychoeducation and exercise intervention was applied to the experimental group four times a week for 6weeks; no intervention was applied to the control group. FINDINGS: No difference was seen between the points of pretest QoL of the experimental and control groups (p>0.05). However, according to the posttest, the experimental group's mean score of QoL was higher than the control groups (p<0.05). CONCLUSION: It was found that CBM-based psychoeducation and exercise intervention applied to individuals with AUD affected the QoL positively. CLINICAL RELEVANCE: CBM-based psychoeducation and exercise intervention can be used by nurses to improve AUD individuals' quality of life.

AB - OBJECTIVE: To identify the predictive factors of anxiety and depression in patients with acute coronary syndrome. METHODS: Cross-sectional and retrospective study conducted with 120 patients hospitalized with acute coronary syndrome. Factors interfering with anxiety and depression were assessed. RESULTS: Anxiety was related to sex, stress, years of education, and depression, while depression was related to sex, diabetes mellitus, obesity, years of education, and trait anxiety. CONCLUSIONS: Obesity and anxiety were considered predictive factors for depression, while depression and fewer years of education were considered predictive factors for anxiety. PMID- 29179820 TI - Early Intervention in Psychosis: Health of the Nation Outcome Scales (HoNOS) Outcomes From a Five-Year Prospective Study. AB - INTRODUCTION: Over the last two decades, mental health services internationally have shifted towards intervening early in psychosis. The critical period for intervention is estimated to be five-years and many specialised programs target early psychosis. AIM/QUESTION: This prospective cohort study aimed to evaluate five-year outcomes from an early psychosis program (EPP) that adopted an integrated model, providing nursing and multidisciplinary community mental healthcare to clients aged 16-65years, beyond the typical age range of 16 25years. METHOD: We examined one routine outcome measure, the Health of the Nation Outcome Scales (HoNOS) across episodes of care for clients receiving EPP over a 5year period (n=239), comparing these results with HoNOS outcomes in an Australian national dataset for all public mental health clients. RESULTS: HoNOS improvements were highly significant from intake to discharge and from review to discharge for EPP clients, and these compared well with national outcome performance. CONCLUSION: There is potential for mental health nurses and other clinicians to significantly improve client symptoms and functioning, in a model of early psychosis treatment beyond a youth focus.

AB - Analyzing stories from those who have suffered catastrophic loss from flood may offer a means to better understand recovery of the survivors from their perspective. The purpose of this research was to examine the lived experience of those who faced catastrophic loss from flood. Stories were gathered from eight participants, who experienced catastrophic loss of home and possessions resultant of massive flooding. Following analysis, three "turning points" were identified within the story plot which included: Facing the devastation, Embracing the rebuilding, and Developing inner strength. Themes within the turning points were identified demonstrating transformational perspectives of self and world.

AB - AIM: The purpose of this study was to identify the relationships of mental health and internet use in Korean adolescents. Also, it was intended to provide guidelines for reducing internet overuse based on the influencing factors of internet use. METHODS: Participants in this study were convenient sampling, and selected middle and high school students in Incheon metropolitan city, South Korea. Internet use and mental health of adolescents were measured by self reported instruments. This study was carried out from June to July 2014. 1248 participants were collected overall except for insufficient data. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression. RESULTS: There were significant correlations between mental health and internet use. The significant influencing factors of internet use were normal internet use group, mental health, middle school, internet using time on weekends (3h or more), internet using time at a time (3h or more), and high school record. These six variables accounted for 38.1% of internet use. CONCLUSIONS: The results of this study will be used as guidelines for reducing internet overuse of adolescents.

AB - OBJECTIVE: The questionnaire EssenCES (Essen Climate Evaluation Schema) is a widely used instrument to assess social climate in forensic psychiatric and correctional institutions. The purpose of this study was to evaluate the EssenCES in a general psychiatric setting, where it had not previously been evaluated. DESIGN: 648 staff members and 551 patients from 47 general psychiatric wards across 16 hospitals in Germany completed the EssenCES. Factor-, correlation- and scale-analyses were carried out to inspect the questionnaire's properties. RESULTS: The proposed three-dimensional factor structure of the instrument was confirmed. Results indicated that the EssenCES subscales Patients' Cohesion and Experienced Safety had high internal consistency, whereas elimination of item 16 would improve the internal consistency of Therapeutic Hold. Correlations between the EssenCES subscales and other measures supported the validity of the questionnaire. CONCLUSION: The results suggest that the EssenCES is suitable for usage in general psychiatric settings. Along with its brevity, it seems useful as an economic and valid screening instrument for a ward's social climate. Reasons are given why item 16 should be retained. PMID- 29179826 TI - Individual Factors Affecting Self-esteem, and Relationships Among Self-esteem, Body Mass Index, and Body Image in Patients With Schizophrenia. AB - The purposes of this study were to identify correlations between body mass index, body image, and self-esteem in patients with schizophrenia and to analyse the specific factors affecting self-esteem. This study had a descriptive design, utilising a cross-sectional survey. Participants were patients with schizophrenia who were admitted to a mental health facility in South Korea. A total of 180 questionnaires were distributed, and an appropriate total sample size of 167 valid questionnaires was analysed. Self-esteem was significantly correlated with body image, the subscale of appearance orientation, and body areas satisfaction. However, body mass index exhibited no significant correlation with any variable. The variables found to have a significant explanatory power of 21.4% were appearance orientation and body areas satisfaction. The explanatory power of all factors was 33.6%. The self-esteem of patients with schizophrenia was influenced by body mass index and body image. The positive symptoms of schizophrenia can be controlled by medication, whereas negative symptoms can be improved through education and nursing care with medication. Thus, psychiatric nurses should develop education and care programs that contribute to the positive body image and self-esteem of patients with schizophrenia.

AB - This article describes the development of a 6-week multiple caregiver group intervention for primary caregivers of adolescents diagnosed with Oppositional Defiant Disorder or Conduct Disorder in low-income African American families. The intervention is aimed at increasing the primary caregivers' self-efficacy in managing interactions within the family and especially with child serving educational, mental health, juvenile justice, and child welfare systems. Development of the intervention involved seven iterative activities performed in a collaborative effort between an interdisciplinary academic team, community engagement specialists, members of the targeted population, and clinical partners from a large public mental health system. The intervention development process described in this article can provide guidance for teams that aim to develop new mental health interventions that target specific outcomes in populations with unique needs. PMID- 29179828 TI - Reducing the Risk of Cardiovascular Diseases in Non-selected Outpatients With Schizophrenia: A 30-Month Program Conducted in a Real-life Setting. AB - BACKGROUND: The most common cause of premature death in people with schizophrenia is cardiovascular disease, partially explained by an unhealthy lifestyle, smoking, poor diet and sedentary behavior. We aimed to reduce cardiovascular risk factors. METHOD: Naturalistic follow-up study with 54 long-term-treated non selected outpatients with schizophrenia. The 30-month program consisted of individual guidance, group sessions and normal treatment and care offered in our clinic. RESULTS: On average, the participating women reduced their waist circumference by 11.4cm (P=0.037), whereas the participating men increased their waist circumference by 3.3cm (P=0.590). Patients' consumption of fast food was reduced from 1.2 to 0.8 times/week (P=0.016), just as their consumption of soft drinks was reduced from 0.7 to 0.1l/day (P=0.006). Their consumption of coffee increased from 1.6 to 2.5 cups/day (P=0.086). The time women spent on light physical activity increased from 134 to 469min/week (P=0.055). The number of daily cigarettes smoked was reduced by 25.7% for all smokers. CONCLUSIONS: Our program showed that it is possible for women but not for men to reduce their risk factors for developing cardiovascular disease. The program is manageable in most outpatient clinics and can be performed by nursing staff interested in physical health with support from and in cooperation with medical doctors, psychiatrist and leaders/managers. PMID- 29179829 TI - The Impact of Mental Health Reform on Mental Illness Stigmas in Israel. AB - This study examined public perception of stigmas relating to mental illness six months after a reform, which integrated mental health care into primary care in Israel. The results reveal that the public feels uncomfortable seeking referral to mental health services through the public health system, with Arab Israelis and men expressing lower levels of comfort than did Jewish Israelis. The current reform has not solved the issue of public stigma regarding mental health care. The study suggests that the current reforms must be accompanied over time with appropriate public education regarding mental illness. PMID- 29179830 TI - Categorising Patients Mental Illness by Medical Surgical Nurses in the General Hospital Ward: A Focus Group Study. AB - AIM: To gain insight into medical surgical nurses' process(es) of categorising mental illness in general hospitals. BACKGROUND: Categorising patients is a daily social practice that helps medical surgical nurses understand their work and actions. Medical surgical nurses' categorising of mentally ill patients in general hospitals is a means in which they articulate their understanding of mental illness and perform their clinical practice. How medical surgical nurses categorise, and the impact that categorising can have on their work practices is poorly understood. DESIGN: A focus group study. METHOD: Focus group discussions (n=2) of medical surgical nurses' understanding and experience of delivering care to patients with mental illness in a general tertiary referral hospital were conducted in November 2014. Discourse analysis was used to analyse the transcribed data to uncover how participants made discursive evaluations and how this related to their daily clinical practice. RESULTS: The analysis uncovered participant's use of four categories of mentally ill patients: the managed, the unpredictable, the emotional and the dangerous. For participants these categories explained and justified their clinical practice as linked to the challenges and barriers they experienced in providing effective care within the larger healthcare organisation. CONCLUSION: The language used by medical/surgical reflects the wider discourse of managerialism in healthcare organisations. The recognition of these categories can be used by educators, liaison mental health services and policy makers to reconsider service design and learning opportunities for medical surgical nurses to reduce stigmatisation of patients with mental illness. PMID- 29179832 TI - Capturing the Interpersonal Process of Psychiatric Nurses: A Model for Engagement. AB - Staff members' engagement with patients is a critical element of inpatient psychiatric care, essential to safety, the hospitalization experience and the development of a culture of care. Currently broad concerns exist around the amount of time inpatient psychiatric nurses expend in patient engagement and the quality of these interactions. In this paper we present a model of engagement that clarifies necessary skills to support the engagement process. The model is based on Peplau's theory of interpersonal relations, patients' ideas on healing elements of psychiatric hospitalization and research on inpatient therapeutic relationships. We are currently using this model for a web-based teaching/learning course to cultivate interpersonal engagement, and to explicate how through operationalizing their inpatient role, nurses support patients in the development of their mental health and well-being. PMID- 29179831 TI - Improving metabolic monitoring rate for young people aged 35 and younger taking antipsychotic medications to treat a psychosis: A literature review. AB - Young people aged 35 and younger who are taking antipsychotic medications to treat a psychosis are a high risk for developing metabolic syndrome due to the adverse effects of the medications. This paper reports the finding of a review of literature to identify interventions to improve metabolic monitoring rates in this group. A review of 478 studies identified 15 articles which met the inclusion criteria. Five articles reported single-intervention studies and the remaining integrated two or more interventions to improve uptake level of metabolic monitoring. As metabolic syndrome can be detected early through metabolic monitoring in young people taking antipsychotics, early intervention is important to improve their physical health trajectory. PMID- 29179833 TI - Does Assertive Community Treatment Reduce the Use of Compulsory Admissions? AB - BACKGROUND: The growing number of compulsory admissions in Denmark and other countries is a compelling challenge. We hypothesized that Assertive Community Treatment (ACT) may have the quality to reduce the use of several type of coercion including compulsory admissions. Although ACT is not designed for coercion prevention, it may prove efficient in averting major crisis among the included patients. Studies in Denmark showed that ACT has a major and significant advantage in reducing number and length of admissions. METHODS/DESIGN: We collected service data from National Case Register at three psychiatric hospitals, which constitutes the inpatient and outpatient mental health services in the North Denmark Region. Data included psychiatric and somatic service use among 240 patients starting in ACT. Primary measure concerned the extent to which ACT might reduce compulsory admissions. RESULTS: During a five years period patients allocated to ACT show decreasing admission trends. In comparison with all other psychiatric service users, we found a significant difference in trends concerning voluntary admissions and involuntary admissions according to the dangerous criterion, and decrease in number of contacts to Psychiatric Emergency Room (PER) CONCLUSION: An assertive approach undoubtedly reduces hospitalization including some involuntary admissions. ACT is preferable from both team and patient perspectives, and further caused reduction of PER visits compared to standard treatment. PERSPECTIVES: The criterion of Severe Mental Illness (SMI) may be revised to facilitate ACT to be offered to a larger group of SMI patients. In addition, introduction of Crisis Intervention Teams should be considered and allocated to PER. PMID- 29179836 TI - Introduction. PMID- 29179834 TI - Chronic Sorrow in the Elderly.

AB - BACKGROUND: The receptor of parathyroid hormone and parathyroid hormone-related protein (PTH/PTHrp) is located in the cell membrane of target tissues - kidney and osteoblasts. It is a G protein-coupled-receptor whose Gsalpha subunit is encoded by the GNAS gene. Our aim was to study whether the single nucleotide polymorphism (SNP) T393C of the GNAS gene is associated with renal stones, bone mineral density (BMD), or bone remodelling markers in primary hyperparathyroidism (PHPT). METHODS: An analysis was made of clinical and biochemical parameters and densitometric values in three areas and their relationship with the T393C SNP of the GNAS gene in 261 patients with primary hyperparathyroidism and in 328 healthy controls. Genotyping was performed using the Custom Taqman(r) SNP Genotyping assay. RESULTS: The genotype frequencies of GNAS T/C 393 were similar in the control and PHPT groups. No association was found between genotypes and clinical expression of PHPT (renal stones and bone fractures). A nonstatistically significant trend was seen to lower BMD in the lumbar spine, femoral neck, and total hip in both PHPT and control C homozygote subjects. CONCLUSION: Genetic susceptibility to PHPT related to the GNAS T393C polymorphism or a major influence in its development and clinical expression were found. A C allele related susceptibility to lower BMD in trabecular bone in both PHPT and control subjects is not sufficient to suggest a more severe clinical expression of PHPT. This trend may be considered as a basis for further studies with larger sample sizes and complementary functional evaluation. PMID- 29179856 TI - Learning curve of thyroid fine-needle aspiration biopsy. AB - BACKGROUND: Fine-needle aspiration biopsy (FNAB) is the reference procedure for thyroid nodule evaluation. Its main limitation are inadequate samples, which should be less than 20%. OBJECTIVE: To analyze the learning curve of the procedure by comparing the results of a non-experienced endocrinologist (endocrinologist 2) to those of an experienced one (endocrinologist 1). MATERIAL AND METHODS: Sixty FNABs were analyzed from February to June 2016. Each endocrinologist made 2punctures of every nodule in a random order. This order and the professional making every puncture were unknown to the pathologist who examined the samples. RESULTS: Endocrinologist 1 had a higher percentage of diagnoses than endocrinologist 2 (82% vs. 72%, P=.015). In the first 20 FNABs, the difference between both physicians was remarkable and statistically significant (80% vs. 50%, P=.047). In the following 20 FNABs, the difference narrowed and was not statistically significant (90% vs. 65%, P=.058). In the final 20 FNABs, the difference was minimal and not statistically significant (75% vs. 70%, P=.723). CONCLUSIONS: The learning curve of ultrasound-guided FNAB may be completed in a suitable environment by performing it at least 60 times. Although the guidelines recommend at least 3punctures per nodule, 2are enough to achieve an accurate percentage of diagnoses. PMID- 29179857 TI - Transition from intravenous insulin to subcutaneous long-acting insulin in critical care patients on enteral or parenteral nutrition. AB - BACKGROUND AND AIMS: The optimal initial dose of subcutaneous (SC) insulin after intravenous (IV) infusion is controversial, especially in patients receiving continuous enteral nutrition (EN) or total parenteral nutrition (TPN). The aim of this study was to evaluate the strategy used at our hospital intensive care unit (ICU) in patients switched from IV insulin to SC insulin glargine while receiving EN or TPN. DESIGN AND METHODS: A retrospective analysis was made of 27 patients on EN and 14 on TPN switched from IV infusion insulin to SC insulin. The initial dose of SC insulin was estimated as 50% of the daily IV insulin requirements, extrapolated from the previous 12h. A corrective dose of short-acting insulin (lispro) was used when necessary. RESULTS: Mean blood glucose (BG) level during SC insulin treatment was 136+/-35mg/dL in the EN group and 157+/-37mg/dL in the TPN group (p=0.01). In the TPN group, mean BG was >180mg/dL during the first three days after switching, and a 41% increase in the glargine dose was required to achieve the target BG. In the EN group, mean BG remained <180mg/dL throughout the days of transition and the dose of glargine remained unchanged. CONCLUSIONS: In the transition from IV to SC insulin therapy, initial insulin glargine dose estimated as 50% of daily IV insulin requirements is adequate for patients on EN, but inadequate in those given TPN.

AB - OBJECTIVES: Human papillomavirus (HPV) as a risk factor in oropharyngeal squamous cell carcinoma (OPSCC) is well established. However, accumulating data imply that the OPSCC concept is too unspecific with regard to HPV prevalence and clinical importance. To further study the role of HPV in OPSCC by sub-site, a systematic review and meta-analysis was performed. MATERIAL AND METHOD: PubMed was searched and all studies reporting HPV data (p16/HPV DNA/RNA) in both "lymphoepithelial associated" (i.e. tonsillar and base of tongue cancer; TSCC and BOTSCC respectively) and "non-lymphoepithelial" ("other" OPSCC) OPSCC were included. Pooled odds ratios by HPV detection method were analysed using a random effects model. RESULTS: In total, 58 unique patient cohorts were identified. Total HPV prevalence in TSCC/BOTSCC was 56%, 95%CI: 55-57% (59%, 95%CI: 58-60% for TSCC only) as compared to 19%, 95%CI: 17-20%, in "other" OPSCC. Significant association of HPV to TSCC/BOTSCC vs. "other" OPSCC was observed no matter HPV detection method used, but statistical homogeneity was only observed when studies using algorithm based HPV detection were pooled. CONCLUSION: HPV prevalence differs markedly between OPSCC sub-sites and while the role of HPV in TSCC/BOTSCC is strong, the role in "other" OPSCC is more uncertain and needs further evaluation. PMID- 29179863 TI - Comparative study of a novel application of automated HR HPV assay and stability in a previously untested Preservative media. AB - BACKGROUND: The suitability and stability of cervical cells in Novaprep media (NHQ) for certain HPV assays is unknown. METHODS: We evaluated the accuracy of an automated HPV assay (Abbott RealTime HR HPV) for cervical cells prepared in NHQ and NHQ with a pre-treatment to mimic a worst case clinical use, compared to the assay manufacturers media; repeatability and reproducibility of HPV results and the stability of detectable HPV in NHQ over time compared to CE marked liquid based cytology preservatives. Cell lines were used to simulate patient samples. RESULTS: Cells stored in NHQ produced accurate, repeatable and reproducible results. Stability in NHQ was comparable to the best performing LBC, with at least 7 months' stability at 18-25 degrees C, 2-8 degrees C, -20 degrees C and 80 degrees C; and at least 3 months' stability at 40 degrees C. Similar results were obtained for pre-treated NHQ except only 3.5 months' stability at 18-25 degrees C. Cell line samples in all media and concentrations tested were detected appropriately by the assay. CONCLUSIONS: Based on this first stage validation analytical study, cervical cells stored in NHQ are suitable for the Realtime HPV assay. There should be no reservations for inclusion of NHQ in any further validation and clinical performance evaluation of this assay.

AB - OBJECTIVE: To evaluate the acceptability and performance of cervical cancer (CC) screening using visual inspection with acetic acid (VIA) integrated into a rural immunization clinic in Uganda. METHODS/MATERIALS: We conducted a cross-sectional pilot study in rural Uganda. We explored associations between women's characteristics and acceptance of VIA testing. We collected samples for Papanicolaou (Pap) smear testing in a random subset of women and used results from this test as a comparator for assessing VIA performance. RESULTS: We enrolled 625 women of whom 571 (91.4%) accepted and 54 (8.6%) refused CC screening. In the univariate model, age (Odds Ratio (OR)=1.10; p-value<0.001) and employment status (OR 2.00; p-value=0.019) were significantly associated with acceptance of VIA screening. In the multivariate model, no characteristic was independently associated with acceptance of VIA screening after adjusting for other factors. Compared to reference Pap smear, CC screening with VIA had a sensitivity of 50% and a specificity of 97.7%. CONCLUSIONS: CC screening with VIA is highly acceptable in the setting of rural immunization clinics in Uganda. Studies to assess which screening method would be the most effective and cost effective are needed before stakeholders can consider adopting screening programs at scale. PMID- 29179865 TI - What works for human papillomavirus vaccine introduction in low and middle-income countries? AB - Since 2007, low and middle-income countries (LMICs) have gained experience delivering HPV vaccines through HPV vaccination pilots, demonstration projects and national programmes. This commentary summarises lessons from HPV vaccination experiences in 45 LMICs and what works for HPV vaccination introduction. Methods included a systematic literature review, unpublished document review, and key informant interviews. Data were extracted from 61 peer-reviewed articles, 11 conference abstracts, 188 technical reports, and 56 interviews, with quantitative data analysed descriptively and qualitative data analysed thematically. Key lessons are described under five themes of preparation, communications, delivery, coverage achievements, and sustainability. Lessons learnt were generally consistent across countries and projects and sufficient lessons have been learnt for countries to deliver HPV vaccine through phased national rollout rather than demonstration projects. However, challenges remain in securing the political will and financial resources necessary to implement successful national programmes.

HPV-status and SLPI-protein expression were determined in tonsillar SCC (TSCC; n=126). Differentially expressed miRNAs dependent on HPV-status and SLPI expression were detected by microarray; possible binding-sites in SLPI- and HPVE6 mRNAs were determined in silico. Survival rates were estimated testing prognostic values of HPV-status, SLPI- and miRNA-expression. miRNA-array identified 24 up regulated and 10 down-regulated miRNAs in HPV-positive versus HPV-negative TSCC (p<0.01; HPV-positivity: 42.1%). HPV-positivity resulted in two up-regulated miRNAs in SLPI-positive TSCC. Of 16 further miRNAs, eight miRNAs were up- and eight were down-regulated in SLPI-negative TSCC. RT-q-PCR-validation of the four most differentially expressed miRNAs showed that miR-363 is expressed strongest in SLPI-negative/HPV-positive TSSC. In silico-analysis of all differentially expressed miRNAs identified miR-363, miR-210, miR-130a, and miR-181a with possible binding sites in the HPV16-E6-mRNA, but none were predicted in the SLPI mRNA. HPV-positivity, low SLPI-levels and high miR-363-levels are significantly associated with better survival rates. The data presented here show that miR-363 is associated with HPV-positive/SPLI-negative TSCC. The prognostic value of miR 363 suggests a role in the assumed inverse correlation of smoking and SPLI expression in the mode of HPV-infections in tonsillar but possibly also other HNSCC. PMID- 29179867 TI - HPV vaccination of immunocompromised hosts. AB - It is well-established that immunocompromised people are at increased risk of HPV related disease compared with those who are immunocompetent. Prophylactic HPV sub unit vaccines are safe and immunogenic in immunocompromised people and it is strongly recommended that vaccination occur according to national guidelines. When delivered to immunocompromised populations, HPV vaccines should be given as a 3-dose regimen. PMID- 29179869 TI - Overcoming barriers in HPV vaccination and screening programs. AB - The Human Papillomavirus Prevention and Control Board brought together experts to discuss optimizing HPV vaccination and screening programs. Board members reviewed the safety profile of licensed HPV vaccines based on clinical and post-marketing data, reaching a consensus that current safety data is reassuring. Successful vaccination programs used well-coordinated communication campaigns, integrating (social) media to spread awareness. Communication of evidence supporting vaccine effectiveness had beneficial effects on the perception of the vaccine. However, anti-vaccination campaigns have threatened existing programs in many countries. Measurement and monitoring of HPV vaccine confidence over time could help understand the nature and scale of waning confidence, define issues and intervene appropriately using context-specific evidence-based strategies. Finally, a broad group of stakeholders, such as teachers, health care providers and the media should also be provided with accurate information and training to help support prevention efforts through enhanced understanding of the risks and benefits of vaccination. Similarly, while cervical cancer screening through population-based programs is highly effective, barriers to screening exist: awareness in countries with population-based screening programs, access for vulnerable populations, and access and affordability in low- and middle-income countries. Integration of primary and secondary prevention has the potential to accelerate the decrease in cervical cancer incidence. PMID- 29179868 TI - Prevalence and correlates of cervical HPV infection in a clinic-based sample of HIV-positive Hispanic women. AB - OBJECTIVES: Puerto Rico (PR), is the fifth highest jurisdiction of the United States of America (US) with respect to HIV prevalence and the leading in cervical cancer incidence. This cross-sectional study describes the prevalence and correlates of cervical HPV infection among a clinic-based sample of 302 women living with HIV/AIDS in PR. METHODS: Data collection included questionnaires, blood and cervical samples. Multivariable logistic regression models were used to estimate the magnitude of association (adjusted Prevalence odds ratio [aPOR]) between HPV cervical infection and other covariates. RESULTS: Mean age of participants was 40.3 years (+/- 10.3SD). The prevalence of HPV infection was 50.3%; 41.1% for low-risk types and 29.5% for high-risk types. Having >= 10 lifetime sexual partners (aPOR = 2.10, 95% CI:1.02-4.29), an abnormal Pap (aPOR = 3.58, 95% CI:1.93-6.62), active genital warts (aPOR = 3.45, 95% CI:1.60-7.42), and CD4 counts <= 200 (aPOR = 4.24, 95% CI: 1.67-10.78) were positively associated with any cervical HPV infection. Similar results were observed for HR HPV infection. CONCLUSIONS: A high burden of HPV co-infection exists among women living with HIV/AIDS in this population. Given the high incidence of HIV in PR and the higher risk of cervical cancer among women living with HIV/AIDS, HPV vaccination should be promoted in this population. PMID- 29179870 TI - Cutaneous HPV and alpha-mucosal 9-valent HPV sero-status associations. AB - Seroepidemiology of human papillomaviruses (HPV) among men is poorly understood. We examined the association between seropositivity to cutaneous HPV and 9-valent HPV (9vHPV) types. Six hundred men were randomly selected from the HPV Infection in Men (HIM) Study. Archived serum specimens were tested for antibodies against 9vHPV types [low-risk (6/11) and high-risk (16/18/31/33/45/52/58)], and 14 cutaneous types, including beta-types 5/8/12/14/17/22/23/24/38/47, alpha-type-27, gamma-type-4, u-type-1, and nu-type-41, using a GST L1-based multiplex serology assay. Risk factor data were collected through questionnaires. Logistic regression was used to evaluate associations between mucosal and cutaneous HPV types. Approximately 21% of men were positive for >= 1 cutaneous HPV type, and >= 1 nine-valent HPV vaccine type at the same time. Men who were seropositive for any-cutaneous HPV were nearly twice as likely to be seropositive for 9vHPV (adjusted odds ratio (AOR) = 1.97, 95% confidence interval (CI): 1.30-2.99), high risk (AOR = 1.83; 95% CI: 1.04-3.20), low-risk (AOR = 1.92; 95% CI: 1.16-3.18), and four-valent, 4vHPV, (AOR = 2.01; 95% CI: 1.25-3.21). Type-specific cutaneous HPV seropositivity (types: 8/14/17/23/38/27/4/1) was also positively associated with seropositivity to 9vHPV, high-risk, and low-risk categories. These data indicate that exposure to cutaneous HPV and 9vHPV types is common. Future longitudinal studies are needed to assess the temporality of these associations. PMID- 29179872 TI - Improving skills and institutional capacity to strengthen adolescent immunisation programmes and health systems in African countries through HPV vaccine introduction. AB - Several African countries have recently introduced or are currently introducing the HPV vaccine, either nationwide or through demonstration projects, while some countries are planning for introduction. A collaborative project was developed to strengthen country adolescent immunisation programmes and health systems in the African Region, addressing unique public health considerations of HPV vaccination: adolescents as the primary target group, delivery platforms (e.g. school-based and facility based), socio-behavioural issues, and the opportunity to deliver other health interventions alongside HPV vaccination. Following a successful "taking-stock" meeting, a training programme was drafted to assist countries to strengthen the integration of adolescent health interventions using HPV vaccination as an entry point. Two workshops were conducted in the Eastern and Southern African Regions. All countries reported on progress made during a final joint symposium. Of the 20 countries invited to participate in either of the workshops and/or final symposium, 17 countries participated: Angola, Botswana, Ethiopia, Kenya, Malawi, Mauritius, Mozambique, Namibia, Rwanda, Seychelles, South Africa, South Sudan, Swaziland, Tanzania, Uganda, Zambia and Zimbabwe. Countries that are currently implementing HPV vaccination programmes, either nationally or through demonstration projects, reported varying degrees of integration with other adolescent health interventions. The most commonly reported adolescent health interventions alongside HPV vaccination include health education (including sexually transmitted infections), deworming and delivering of other vaccines like tetanus toxoid (TT) or tetanus diphtheria (Td). The project has successfully (a) established an African-based network that will advocate for incorporating the HPV vaccine into national immunisation programmes; (b) created a platform for experience exchange and thereby contributed to novel ideas of revitalising and strengthening school-based health programmes as delivery platform of adolescent immunisation services and other adolescent health interventions, as well as identifying ways of reaching out-of-school girls through facility and community based programmes; and (c) laid a foundation for incorporating future adolescent vaccination programmes. PMID- 29179871 TI - Modulation of antigen presenting cell functions during chronic HPV infection. AB - High-risk human papillomaviruses (HR-HPV) infect basal keratinocytes, where in some individuals they evade host immune responses and persist. Persistent HR-HPV infection of the cervix causes precancerous neoplasia that can eventuate in cervical cancer. Dendritic cells (DCs) are efficient in priming/cross-priming antigen-specific T cells and generating antiviral and antitumor cytotoxic CD8+ T cells. However, HR-HPV have adopted various immunosuppressive strategies, with modulation of DC function crucial to escape from the host adaptive immune response. HPV E6 and E7 oncoproteins alter recruitment and localization of epidermal DCs, while soluble regulatory factors derived from HPV-induced hyperplastic epithelium change DC development and influence initiation of specific cellular immune responses. This review focuses on current evidence for HR-HPV manipulation of antigen presentation in dendritic cells and escape from host immunity. PMID- 29179873 TI - Human papillomavirus (HPV) vaccine coverage achievements in low and middle-income countries 2007-2016. AB - INTRODUCTION: Since 2007, HPV vaccine has been available to low and middle income countries (LAMIC) for small-scale 'demonstration projects', or national programmes. We analysed coverage achieved in HPV vaccine demonstration projects and national programmes that had completed at least 6 months of implementation between January 2007-2016. METHODS: A mapping exercise identified 45 LAMICs with HPV vaccine delivery experience. Estimates of coverage and factors influencing coverage were obtained from 56 key informant interviews, a systematic published literature search of 5 databases that identified 61 relevant full texts and 188 solicited unpublished documents, including coverage surveys. Coverage achievements were analysed descriptively against country or project/programme characteristics. Heterogeneity in data, funder requirements, and project/programme design precluded multivariate analysis. RESULTS: Estimates of uptake, schedule completion rates and/or final dose coverage were available from 41 of 45 LAMICs included in the study. Only 17 estimates from 13 countries were from coverage surveys, most were administrative data. Final dose coverage estimates were all over 50% with most between 70% and 90%, and showed no trend over time. The majority of delivery strategies included schools as a vaccination venue. In countries with school enrolment rates below 90%, inclusion of strategies to reach out-of-school girls contributed to obtaining high coverage compared to school-only strategies. There was no correlation between final dose coverage and estimated recurrent financial costs of delivery from cost analyses. Coverage achieved during joint delivery of HPV vaccine combined with another intervention was variable with little/no evaluation of the correlates of success. CONCLUSIONS: This is the most comprehensive descriptive analysis of HPV vaccine coverage in LAMICs to date. It is possible to deliver HPV vaccine with excellent coverage in LAMICs. Further good quality data are needed from health facility based delivery strategies and national programmes to aid policymakers to effectively and sustainably scale-up HPV vaccination. PMID- 29179874 TI - HPV genotype-specific concordance between EuroArray HPV, Anyplex II HPV28 and Linear Array HPV Genotyping test in Australian cervical samples. AB - PURPOSE: To compare human papillomavirus genotype-specific performance of two genotyping assays, Anyplex II HPV28 (Seegene) and EuroArray HPV (EuroImmun), with Linear Array HPV (Roche). METHODS: DNA extracted from clinican-collected cervical brush specimens in PreservCyt medium (Hologic), from 403 women undergoing management for detected cytological abnormalities, was tested on the three assays. Genotype-specific agreement were assessed by Cohen's kappa statistic and Fisher's z-test of significance between proportions. RESULTS: Agreement between Linear Array and the other 2 assays was substantial to almost perfect (kappa = 0.60 - 1.00) for most genotypes, and was almost perfect (kappa = 0.81 - 0.98) for almost all high-risk genotypes. Linear Array overall detected most genotypes more frequently, however this was only statistically significant for HPV51 (EuroArray; p = 0.0497), HPV52 (Anyplex II; p = 0.039) and HPV61 (Anyplex II; p=0.047). EuroArray detected signficantly more HPV26 (p = 0.002) and Anyplex II detected more HPV42 (p = 0.035) than Linear Array. Each assay performed differently for HPV68 detection: EuroArray and LA were in moderate to substantial agreement with Anyplex II (kappa = 0.46 and 0.62, respectively), but were in poor disagreement with each other (kappa = -0.01). CONCLUSIONS: EuroArray and Anyplex II had similar sensitivity to Linear Array for most high-risk genotypes, with slightly lower sensitivity for HPV 51 or 52. PMID- 29179875 TI - Surgical staging identified false HPV-negative cases in a large series of invasive cervical cancers. AB - OBJECTIVE: We examined a large series of biopsy-proven invasive cervical cancers with surgical staging and HPV re-testing to estimate the relevance of HPV negative cervical cancers in a Caucasian population. METHODS: We prospectively collected smears from 371 patients with a biopsy-proven diagnosis of cervical cancer for HC2 testing of high-risk HPV (HR-HPV). In HC2-negative cases, smears and paraffin embedded tissue blocks underwent additional HPV genotyping. RESULTS: HC2 tests showed 31/371 cases (8.8%) had negative findings. Surgical staging showed that 21/31 HC2-negative cases (68%) were not cervical cancer. Overall, 340/350 cases of primary cervical cancer confirmed by surgical staging tested HC2 positive (97.2%). Non-high-risk HPV subtypes were detected in five cases (one HPV 53, one HPV-70, and three HPV-73) and high-risk subtypes in four patients with HC2-negative cervical cancer (two HPV 16 and two HPV-18). The remaining case, a primary undifferentiated carcinoma of the uterine cervix, tested negative for HPV DNA with all tests. CONCLUSIONS: The main explanation for HPV-negative cervical cancer was a false diagnosis, followed by cancers associated with non-HR-HPV types, and false-negative HR-HPV results. Truly HPV negative seem to be very rare in Caucasian populations. Retrospective analyses without surgical staging may overestimate the proportion of HPV negative cervical cancers. PMID- 29179876 TI - Syndemic synergy of HPV and other sexually transmitted pathogens in the development of high-grade anal squamous intraepithelial lesions. AB - BACKGROUND: Anal intraepithelial neoplasia is associated with high-risk human papillomavirus (hrHPV) as a precursor to anal cancer. However, factors other than hrHPV are likely to be involved and further study of cofactors is required because of the possibility of syndemic interactions. METHODS: Three hundred and fourteen patients underwent 457 operations. Histopathology and hrHPV testing using the Digene Hybrid Capture 2 (HC 2) method were performed. Demographic factors and sexually transmissible infections (STIs) were recorded. RESULTS: Results showed that hrHPV alone was associated with HSIL (OR = 4.65, p < 0.001). None of the other STIs were alone associated with HSIL but amplification of risk was found when hrHPV infection occurred with HIV (OR = 11.1); syphilis (OR = 5.58); HSV 2 (OR = 7.85); gonorrhoea (OR = 6.45) and some other infections. CONCLUSIONS: These results suggest that hrHPV is a sufficient cause of anal HSIL. Seropositivity for HIV, HSV 2, T. pallidum, HBV and HCV and a history of gonorrhoea or chlamydia exert a powerful amplifying factor increasing the risk of HSIL above the risk with hrHPV alone. Other co-factors which are associated with an increased risk of HSIL are increased age, male gender, MSM behaviour and self reported history of more than 50 sexual partners. This pattern of disease in patients with warts is characteristic of a syndemic with potential serious increased risk of anal carcinoma. PMID- 29179877 TI - Psychosocial correlates of HPV vaccine acceptability in college males: A cross sectional exploratory study. AB - BACKGROUND: Most college males are not immunized against the human papillomavirus (HPV) and are at high risk of HPV infection. Most research of correlates of HPV vaccine acceptability in college males has assessed vaccine acceptability as a binary outcome, e.g., vaccinated or not vaccinated, without considering that some students may not even be aware that the HPV vaccine can be given to males. Our objective was to evaluate the psychosocial correlates of HPV acceptability in college males, based on multiple stages of HPV decision-making. METHODS: We used an online questionnaire to collect data from college men aged 18-26 enrolled at three Canadian universities between September 2013 and April 2014. Vaccine acceptability assessment was informed by the six-stage decision-making Precaution Adoption Process Model (PAPM). We sought information on socio-demographics, health behaviors, HPV vaccine benefits and barriers, worry, susceptibility, severity related to HPV infection and social norms. HPV and HPV vaccine knowledge was measured with validated scales. Psychosocial correlates of HPV vaccine acceptability were assessed with bivariate and multivariate multinomial logistic regression. Actual and perceived HPV and HPV vaccine knowledge scores were calculated. RESULTS: The final sample size was 428. Most male college students were unaware that the HPV vaccine could be given to males, unengaged or undecided about getting the HPV vaccine. Significant correlates of higher HPV vaccine acceptability were: increased HPV knowledge, having discussed the HPV vaccine with a healthcare provider, and social norms. Being in an exclusive sexual relationship was significantly associated with lower HPV vaccine acceptability. Students' actual HPV and HPV vaccine knowledge was low and positively correlated to their perception about their HPV knowledge. CONCLUSIONS: We provided a fine tuned analysis of psychosocial correlates of HPV vaccine acceptability in college males who are in the early stages of HPV vaccine decision-making. Interventions are needed to increase HPV and HPV vaccine knowledge in college males. PMID- 29179878 TI - Oxidative stress and diabetes: Glucose response in the cROSsfire. AB - In this issue of the Biomedical Journal, we discuss the emerging role of reactive oxygen species (ROS) in the development of insulin resistance and ultimately type 2 diabetes. We focus also on research investigating the outcome of in vitro fertilization after laproscopic surgery for ovarian endometriosis. Finally, we learn the results of a study on the hunt for new probiotic bacteria. PMID- 29179880 TI - The etiology of oxidative stress in insulin resistance. AB - Insulin resistance is a prevalent syndrome in developed as well as developing countries. It is the predisposing factor for type 2 diabetes mellitus, the most common end stage development of metabolic syndrome in the United States. Previously, studies investigating type 2 diabetes have focused on beta cell dysfunction in the pancreas and insulin resistance, and developing ways to correct these dysfunctions. However, in recent years, there has been a profound interest in the role that oxidative stress in the peripheral tissues plays to induce insulin resistance. The objective of this review is to focus on the mechanism of oxidative species generation and its direct correlation to insulin resistance, to discuss the role of obesity in the pathophysiology of this phenomenon, and to explore the potential of antioxidants as treatments for metabolic dysfunction. PMID- 29179879 TI - P2X4: A fast and sensitive purinergic receptor. AB - Extracellular nucleotides have been recognized as important mediators of activation, triggering multiple responses via plasma membrane receptors known as P2 receptors. P2 receptors comprise P2X ionotropic receptors and G protein coupled P2Y receptors. P2X receptors are expressed in many tissues, where they are involved in a number of functions including synaptic transmission, muscle contraction, platelet aggregation, inflammation, macrophage activation, differentiation and proliferation, neuropathic and inflammatory pain. P2X4 is one of the most sensitive purinergic receptors (at nanomolar ATP concentrations), about one thousand times more than the archetypal P2X7. P2X4 is widely expressed in central and peripheral neurons, in microglia, and also found in various epithelial tissues and endothelial cells. It localizes on the plasma membrane, but also in intracellular compartments. P2X4 is preferentially localized in lysosomes, where it is protected from proteolysis by its glycosylation. High ATP concentration in the lysosomes does not activate P2X4 at low pH; P2X4 gets activated by intra-lysosomal ATP only in its fully dissociated tetra-anionic form, when the pH increases to 7.4. Thus, P2X4 is functioning as a Ca2+-channel after the fusion of late endosomes and lysosomes. P2X4 modulates major neurotransmitter systems and regulates alcohol-induced responses in microglia. P2X4 is one of the key receptors mediating neuropathic pain. However, injury induced upregulation of P2X4 expression is gender dependent and plays a key role in pain difference between males and females. P2X4 is also involved in inflammation. Extracellular ATP being a pro-inflammatory molecule, P2X4 can trigger inflammation in response to high ATP release. It is therefore involved in multiple pathologies, like post-ischemic inflammation, rheumatoid arthritis, airways inflammation in asthma, neurodegenerative diseases and even metabolic syndrome. Although P2X4 remains poorly characterized, more studies are needed as it is likely to be a potential therapeutic target in these multiple pathologies. PMID- 29179881 TI - Chang Gung Research Database: A multi-institutional database consisting of original medical records. AB - BACKGROUND: The Chang Gung Research Database (CGRD) is a de-identified database derived from original medical records of Chang Gung Memorial Hospital (CGMH), which comprises seven medical institutes located from the northeast to southern regions of Taiwan. The volume of medical services performed in CGMH is large, and clinical and scientific studies based on the CGRD are reported to be of high quality. However, the CGRD as a useful database for research has not been analyzed before. The objective of the study was to analyze the CGRD with regard to its characteristics and coverage of Taiwan's population. METHODS: We performed a nationwide cohort study using population-based data from the Taiwan National Health Insurance Research Database (NHIRD). All patients who had any medical record of outpatient visits or admission between January 1, 1997, and December 31, 2010, were included, and the sex ratio, age distribution, socioeconomic status, urbanicity, severity of illness, prevalence of specific disease, and coverage of the CGRD were analyzed. RESULTS: The sex ratio, age distribution, socioeconomic status, and urbanicity of the population of the CGRD are different from those of Taiwan NHIRD and medical centers in Taiwan (all the pairwise p < 0.05). The severity of comorbidities, and prevalence of specific diseases of the population of the CGRD are significantly higher than those of Taiwan NHIRD and medical centers in Taiwan for both outpatient and inpatient samples (all the pairwise p < 0.05). The overall coverage of the CGRD was 21.2% for outpatients and 12.4% for inpatients. The disease-specific coverage of the CGRD was 27-34% for outpatients and 14-21% for inpatients. CONCLUSIONS: The CGRD is a multi institutional, original medical record-based research database with high overall and disease-specific coverage of Taiwan. The population of the CGRD has significantly higher severity of comorbidities, and prevalence of specific diseases than those of Taiwan NHIRD and medical centers in Taiwan. PMID- 29179882 TI - Probiotic potential of Lactobacilli with antagonistic activity against pathogenic strains: An in vitro validation for the production of inhibitory substances. AB - BACKGROUND: Probiotics, live cells with different beneficiary characteristics, have been extensively studied and explored commercially in many different products in the world. Their benefits to human and animal health have proven in hundreds of scientific studies. Based on rich bibliographic material, Curd is the potential source of probiotic Lactobacilli. METHOD: The aim of the present study was to observe Lactobacilli with probiotic potential activities from different curd samples for isolation, identification and characterization of Lactobacillus species. RESULTS: Among the samples, thirty lactic acid bacterial strains were isolated, sixteen (16/30) best Lactobacillus isolates were selected by preliminary screening as potential probiotic for acid and bile tolerance, further confirmed using 16s rRNA identification. All the selected Lactobacillus isolates were then characterized in vitro for their probiotic characteristics and antimicrobial activities against pathogens and aggregation studies. The results indicated that selected potential probiotic isolates (T2, T4 and T16) were screened and confirmed as Lactobacillus. The isolates produced positive tolerance to excited pH, NaCl and bile salts, also revealed noticeable antimicrobial activities against pathogens. All the Lactobacillus isolates were susceptible to clinical antibiotics used. Besides, T2 isolate was constituted to retain stronger auto and co-aggregation and cell surface hydrophobicity capacity. CONCLUSION: Based on the drawn results, T2, T4 and T16 Lactobacillus isolates were recognised as ideal, potential in vitro antimicrobial probiotic isolates against pathogens and studies are needed further in-vivo assessment and human health benefits in their real-life situations. PMID- 29179883 TI - Shifting trend of tubercular lymphadenitis over a decade - A study from eastern region of India. AB - BACKGROUND: The incidence of tuberculosis (TB) is changing in India. The commonest extra pulmonary manifestation of TB is tuberculous lymphadenitis. AIMS AND OBJECTIVES: To detect changes in occurrence of TB lymphadenitis by comparing current data with that from 10 years back. METHODS: Fine Needle Aspiration Cytology (FNAC) findings of patients presenting with lymphadenopathy between January 2014 and December 2015 were included in the study as current data. Cases of TB lymphadenitis were analysed for cyto-morphological patterns and frequency of acid fast bacilli (AFB) positivity. Cytological data of patients with lymphadenopathy between January 2002 and December 2003, were collected from records. Subsequently, comparison was done between previous data and current observation. RESULTS: Total 302 cases of lymphadenopathy were included in 2014 and 2015. Tuberculous lymphadenitis accounted for 96 (31.7%) cases, among which AFB was present in 47 (49%) cases. Data collected from registers of the years 2002 and 2003 included 318 cases where tuberculous lymphadenitis accounted for 161 (50.6%) cases and AFB was detected in 101 (63%) patients. Maximum AFB positivity was found in smears with caseous necrosis only. CONCLUSION: Presently occurrence of TB lymphadenopathy has reduced compared to the period of 2002-2003. Despite this declining trend, the disease continues to be one of the leading causes of lymphadenopathy in both periods. PMID- 29179884 TI - Mortality pattern in otorhinolaryngology ward: A 5 years retrospective study at an urban tertiary health care center in India. AB - BACKGROUND: To recognize deaths in the otorhinolaryngology indoor wards, determine the reason behind the mortalities and recommend modifications for betterment of patient care and surgical outcomes. METHOD: Data was collected from the mortality register, operation theatre registers, ward registers and case notes of patients declared dead at an urban tertiary health care center in India for a period of 5 years; from January 2012 to December 2016. The data included date of admission, age, sex, educational status, residence, and clinical diagnosis, course of hospital stay and medical cause of death. Data acquired was reviewed and statistically interpreted and presented in graphical and descriptive formats. RESULTS: 6157 admissions were made in otorhinolaryngology (ENT) ward in the 5 year period which included 3969 males and 2188 female patients. 58 deaths were recorded during this period which gives overall death per admission crude mortality rate of 9.42% at an average of about 12 (11.60) deaths per year. The major causes of death were malignancy and septicemia. CONCLUSION: The significance of health education, aggressive healthcare campaigns, enhancement of healthcare services and wide accessibility of healthcare services to remote areas has been emphasized. Role of structured study and protocols in the management of serious cases is highlighted along with the need for prompt referral and better interdepartmental cooperation.

PMID- 29179885 TI - Bilaterality of ovarian endometriomas does not affect the outcome of in vitro fertilization/intracytoplasmic sperm injection in infertile women after laparoscopic cystectomy. AB - BACKGROUND: To assess whether the unilateral or bilateral lesions can affect ovarian reserve and pregnancy outcome in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) in infertility patients underwent laparoscopic cystectomy. METHODS: A total of 148 IVF/ICSI cycle in patients who had undergone laparoscopic cystectomy for unilateral or bilateral endometriomas were reviewed retrospectively. There were 103 cycles where laparoscopic cystectomy had been carried out for unilateral endometriomas and 45 cycles after bilateral-side surgery. Primary outcome measures were ovarian reserve and ovarian response. Secondary outcome measures were the implantation rate, clinical pregnancy rate, and live birth rate. RESULTS: The number of dominant follicle on the day of human chorionic gonadotropin (hCG) administration (5.2 +/- 3.1 vs. 4.2 +/- 2.7; p = 0.048), and oocytes retrieved (10.0 +/- 6.9 vs. 7.6 +/- 6.6; p = 0.047) were significantly lower in the bilateral-side group compare with the unilateral-side group. However, the mean number of antral follicle count, metaphase II oocytes, the doses of gonadotropin used, fertilization rate, the rate of good quality embryos transferred, implantation rate and clinical pregnancy, live-birth rate and miscarriage rate were similar between the two groups. CONCLUSION: There were no associations among the bilaterality of ovarian endometriomas, ovarian reserve and pregnancy outcomes in IVF/ICSI cycles. However, bilateral ovarian endometriomas after laparoscopic cystectomy may impair ovarian response as compared to unilateral ovarian endometrioma. PMID- 29179887 TI - Biomechanical Analysis of Dance for Parkinson's Disease: A Paradoxical Case Study of Balance and Gait Effects? AB - OBJECTIVES: This study aimed to measure the effects of a dance training program on subjective and objective balance and gait measures in a person with Parkinson's disease. DESIGN AND SETTING: The participant was measured via clinical scales and biomechanical balance and gait analyses pre- and post-16 weeks of dance participation at the University Center for Arts in Medicine. The dance program consisted of 75 minute sessions three days a week. RESULTS: Improved clinical scales included the Schwab and England scale (+10%), falls efficacy scale (-11 points), six-minute walk (+15.54m), and timed up and go (1.38s). Balance measures during three conditions (eyes open, eyes closed, and narrow stance) all demonstrated an increase (24-112%) in center of pressure path length, velocity (anteroposterior and mediolateral), sway area, and approximate entropy (anteroposterior and mediolateral). Spatiotemporal gait parameters improved during forward walking: velocity (+0.12m/s), cadence (+3.89steps/min), double support time (-2.02%), stride length (+0.07m), stride time (-0.03s), and backward walking: single support (+3.47%), double support (-7.0%), swing time (+3.4%), and stance time (-3.4%). CONCLUSIONS: Classic interpretation of the above measures may indicate a detriment in biomechanical balance effects concomitant with an improvement in gait. Alternative explanations explored suggest this paradox to be illusory. PMID- 29179888 TI - Secondary Prevention of CVD in LMIC: Care for the Growing Affected Population.

The occurrence of drug-related adverse effects for the treatment of osteoporosis has led to a reevaluation of the indications, the duration of treatment and even withdrawal of some drugs from the market. This review has been made from different patient profiles that practitioners will find in usual practice; from patients with hip fracture with cognitive impairment, limitation of their day-to-day living activities and comorbidities, to active patients without any limitations; patients with vertebral fractures and non vertebral fractures where secondary prevention is highly important. In general, antiresorptive drugs (alendronate and risedronate) will be the first choice.

PMID- 29179896 TI - Malignant Pleural Mesothelioma: Diagnosis, Staging, Pitfalls and Follow-up. AB - Malignant pleural mesothelioma is the most common primary neoplasm of the pleura. Imaging evaluation is essential in diagnosis, staging, and assessment of treatment response in malignant pleural mesothelioma. Computed tomography is the most commonly used modality for tumor staging. Assessment of tumor extension and lymph node involvement is essential in imaging evaluation as locally advanced tumors are amenable to resection. Knowledge of the full imaging spectrum of this rare disease, differential diagnosis, staging classification, and the current guidelines for diagnostic evaluation and follow-up are essential in accurate interpretation to optimize patient management. PMID- 29179897 TI - Positron Emission Tomography/Computed Tomography in Esophageal Carcinoma: Applications and Limitations. AB - Squamous cell carcinoma and adenocarcinoma represent approximately 98% of esophageal malignant tumors. During the last 30 years, the incidence of adenocarcinoma has increased in Western countries (including the USA) where adenocarcinoma currently represents more than 60% of esophageal malignancies, although, worldwide, squamous cell carcinoma continues to be the predominant histologic type. Integrated positron emission tomography or computed tomography with 2-[fluorine18] fluro-2-deoxy-d-glucose is used in many institutions routinely as a tool in the initial staging and then repeated after therapy for the assessment of response to neoadjuvant therapy and detection of recurrent disease in patients with esophageal carcinoma. As with any other imaging modality, 2-[fluorine18] fluro-2-deoxy-d-glucose-positron emission tomography or computed tomography has strengths and limitations that should be understood in order to maximize its utility.

AB - Disease relapse remains the first cause of mortality of hematological malignancies after allogeneic hematopoietic stem cell transplantation (allo-HCT). The risk of recurrence is elevated in patients with high-risk cytogenetic or molecular abnormalities, as well as when allo-HCT is performed in patients with refractory disease or with persistent molecular or radiological (PET-CT scan) residual disease. Within the frame of the 7th annual workshops of the francophone society for bone marrow transplantation and cellular therapy, the working group reviewed the literature in order to elaborate unified guidelines for the prevention and treatment of relapse after allo-HCT. For high risk AML and MDS, a post transplant maintenance strategy is possible, using hypomethylating agents or TKI anti-FLT3 when the target is present. For Philadelphia positive ALL, there was a consensus for the use of post-transplant TKI maintenance. For lymphomas, there are no strong data on the use of post-transplant maintenance, and hence a preemptive strategy is recommended based on modulation of immunosuppression, close follow-up of donor chimerism, and donor lymphocytes infusion. For multiple myeloma, even though the indication of allo-HCT is controversial, our recommendation is post transplant maintenance using bortezomib, due to its a good toxicity profile without increasing the risk of GVHD.

They are most commonly found in mediastinal compartments (aortopulmonary window or posterior mediastinum). Computed tomography, magnetic resonance, and specific nuclear medicine radiotracers are routinely used to characterize these lesions and help exclude other more common conditions. Selective angiography is currently used for preoperative embolization and mapping of the vascular supply before surgical resection, rather than for diagnostic purposes alone. PMID- 29179899 TI - Imaging of Metastases in the Chest: Mechanisms of Spread and Potential Pitfalls. AB - Pulmonary and pleural metastases are routinely identified on thoracic computed tomography. Pulmonary metastases are the most common pulmonary neoplasms and commonly originate from primary malignancies of the lung, breast, colon, pancreas, stomach, skin (ie, melanoma), head and neck, and kidney. Metastatic disease to the lungs may occur via 3 routes of spread: hematogenous, lymphatic, and endobronchial. Pleural metastases most commonly originate from primary malignancies of the lung and breast. Mechanisms of pleural metastatic involvement include hematogenous spread, direct invasion from a neighboring tumor, and retrograde lymphatic spread from the mediastinum. Awareness of the spectrum of appearances of metatastic disease in the chest is important in avoiding misinterpretation.

AB - Improvements in surgical technique over the last decade enable surgeons to perform extensive resection and reconstruction in patients presenting with tumors involving the soft tissue or bony structures of the chest wall. The type of surgical resection and its size, depend on the type of tumor resected and its location. In addition to providing a better esthetic result, the reconstruction restores support and functionality of the thoracic cage. The approach to chest wall repair includes primary closure or reconstruction by using transposition flaps, free flaps, prosthetic material, or a mixture of a flap and prosthetic material. PMID- 29179902 TI - Mediastinal (Epipericardial) Fat Necrosis: An Overlooked and Little Known Cause of Acute Chest Pain Mimicking Acute Coronary Syndrome. AB - Necrosis of the fat adjacent to the heart, referred to as pericardial fat necrosis, epipericardial fat necrosis, and mediastinal fat necrosis, is a rare, self-limited condition. It presents as a sudden onset of severe chest pain that mimics symptoms of pulmonary embolism and acute coronary syndrome. Computed tomography (CT) findings are quite typical and consist of a round- or oval-shaped mass-like lesion containing soft tissue and fat density components in the cardiophrenic space. Lack of familiarity with this condition has led in the past to surgical interventions to remove the mass-like mediastinal fat necrosis. Until the early 2000s, surgical removal of these lesions was deemed the treatment of choice, to exclude a neoplasm. However, the observation that the CT findings of the paracardiac mass resemble fat necrosis seen in other parts of the body and its involution on follow-up CT has led to the realization that the process is a benign and self-limiting one. A dramatic shift in the paradigm of treatment has ensued and surgical treatment is no longer advocated. Awareness of this condition is, therefore, vital so as to diagnose it accurately and avoid unnecessary future surgical interventions. PMID- 29179901 TI - CT Imaging of Complications Associated with Continuous-Flow Left Ventricular Assist Devices (LVADs). AB - Heart failure is becoming increasingly prevalent, and more patients are being treated with left ventricular assist devices (LVADs), either as a bridge to transplant or as destination therapy. The use of continuous-flow LVADs is on the rise. LVAD therapy is associated with several classes of complications, including bleeding, thrombosis, and infection. CT imaging can be used effectively to diagnose LVAD complications, including mediastinal hematomas and pericardial, abdominal wall, and retroperitoneal hemorrhage, inflow and outflow graft and aortic thrombi, and driveline and pump pocket infections. CT can also be helpful in cases of device malfunction and can detect outflow graft kinking and inflow cannula misalignment. When interpreting CT scans in patients with LVADs, accessory materials implanted with the device should not be mistaken for hemorrhage or calcification. With training in recognizing LVAD complications, radiologists can play an important role in the evaluation of patients with heart failure. PMID- 29179903 TI - Thoracolithiasis-Computed Tomography Findings of Intrapleural Loose Bodies. AB - Thoracoliths are rare benign intrapleural loose bodies, often containing calcification, that are mobile in the pleural cavity. The presence of these intrapleural nodules is referred to as thoracolithiasis. The exact etiology of thoracoliths is unknown, but they presumably result from a prior episode of mediastinal (epipericardial) fat necrosis. Thoracoliths are usually asymptomatic and incidentally encountered on computed tomography. However, they sometimes pose diagnostic challenges, as a thoracolith may be located within a pleural fissure, and is then indistinguishable from a pulmonary nodule. In addition, migration and rotation of thoracoliths within the pleural space observed on serial computed tomography studies has been reported to raise concern that these might be neoplastic lesions, leading to their surgical removal. Awareness of this benign condition is important in order to avoid unnecessary invasive procedures.

PMID- 29179906 TI - Diagnostic challenges in papillary lesions of the breast. AB - Papillary lesions of the breast comprise a heterogeneous group of diseases ranging from benign and atypical lesions to malignant tumours including non invasive and invasive entities. Although diagnosis of papillary lesions featuring typical histological features is straightforward, a proportion shows overlapping features, posing diagnostic challenges. In addition to being uncommon, the excellent behaviour of papillary tumours reduces the distinguishing value of individual histological features and increases the subjectivity of interpretation of various diagnostic features. Therefore the overall categorisation, which is based on a constellation of subjective features, may vary with subsequent management implications. Concordance studies revealed that recognition of papillary carcinomas (PC) as a malignant entity by pathologists is high, but concordance of its classification into in situ and invasive disease can be problematic, as can assessment of prognostic and predictive factors in the invasive component. Identification of low nuclear grade atypia within benign papillary lesions and its classification into atypia or in situ carcinoma may also pose a diagnostic challenge. Although immunohistochemistry is helpful in evaluation of benign and atypical lesions it has a limited utility in differentiating the majority of PC as non-invasive or invasive disease. Pathologists should be aware of the various entities and the differential diagnosis of each entity, the existence of lesions with overlapping features and should follow the updated guideline recommendation for their diagnosis and management. These rare lesions usually require additional diagnostic work-up and difficult cases should trigger consensus opinion or expert referral. PMID- 29179907 TI - Management and outcomes of isolated paediatric tibial spine fractures. AB - Paediatric fractures of the tibial spine are relatively rare and controversy remains around how these injuries are best managed (Gans et al., 2014; Hargrove et al., 2004). Consequently most non-specialised paediatric units have limited experience of managing these injuries. This study aims to review the management and outcomes of isolated paediatric tibial spine fractures in a tertiary paediatric orthopaedic centre between 2008 and 2016. Data were collected on patient demographics, mechanism of injury, imaging, Meyers and McKeever grade of injury (Meyers and McKeever), management and outcomes, including Cincinnati and Lysholm-Tegner knee scores at a mean of 36 months post-operatively. 40 patients were included, 21 were male and the mean age was 11.8 years. 3 cases were Meyers and McKeever type I, 13 were type II and 24 were type III. 30 underwent operative management comprising of open reduction and single screw fixation, with or without a washer. 9 patients underwent subsequent metalwork removal at a mean of 10 months post-operatively. 10 underwent non-operative management, consisting of cast immobilisation and bracing. 33 patients (83%) were available for follow up. No statistically significant differences were seen in either outcome score between those treated operatively or non-operatively, or between different grades of injury, or if metalwork were removed or not. Our study shows good functional outcomes following paediatric tibial spine fracture. We advocate the use of CT to assess fracture displacement to help guide management. We have shown type I and reducible type II injuries can successfully be managed conservatively and non reducible type II and type III injuries can be successfully treated with open reduction and single screw fixation. In our experience post-operative knee stiffness can persist for up to 6 months but generally improves. Metalwork removal was only indicated if the patient had on going stiffness after this time or if they had on going pain. PMID- 29179908 TI - Preperitoneal pelvic packing is effective for hemorrhage control in open pelvic fractures. AB - BACKGROUND: Open pelvic fractures are life-threatening injuries. Preperitoneal pelvic packing (PPP) has been suggested to be ineffective for hemorrhage control in open pelvic fractures. We hypothesize that PPP is effective at hemorrhage control in patients with open pelvic fractures and reduces mortality. METHODS: Patients undergoing PPP from 2005 to 2015 were analyzed. Patients with open pelvic fractures were defined as direct communication of the bony injury with overlying soft tissue, vagina, or rectum. RESULTS: During the 10-year study, 126 patients underwent PPP; 14 (11%) sustained an open pelvic fracture. After PPP, 1 patient (7%) underwent angioembolization with a documented arterial blush. PPP controlled pelvic hemorrhage in all patients. Overall mortality rate was 7% with one death due to traumatic brain injury. CONCLUSIONS: PPP is effective for hemorrhage control in patients with open pelvic fractures. PPP should be used in a standard protocol for hemodynamically unstable patients with pelvic fractures regardless of associated perineal injuries. PMID- 29179909 TI - Surgical interns: Preparedness for opioid prescribing before and after a training intervention. AB - INTRODUCTION: Exposure to pain management curriculum in medical school is currently variable. This paper reports on formal prescribing education, self perceived prescribing readiness, and prescribing practices among incoming surgical residents before and after a pain management training session. METHODS: Pre-residency survey of thirty surgical interns at a single urban medical center, followed by a repeat survey after an educational session on prescription writing and opioid abuse. RESULTS: Thirty-three percent of respondents had formal education on prescription writing in medical school. Median subjective preparedness to write an opioid prescription was 1.5 (range 1-10) on a 1-10 Likert scale. Ranges of morphine milligram equivalents (MME) prescribed varied from 420-2700 MME for 8 mock surgical scenarios. Post-training, median subjective preparedness increased to 3.5 (range 1-6) and prescription accuracy (the inclusion of a medication, dose, frequency, and duration) improved from 75% to 97% (p < 0.001). Overall, 90% of interns found the training session useful. CONCLUSION: Most surgical interns were not trained in prescribing narcotics in medical school. Improved pain management curriculum is necessary to assure safe and consistent opioid prescriptions. PMID- 29179910 TI - Meaning in meaninglessness: The propensity to perceive meaningful patterns in coincident events and randomly arranged stimuli is linked to enhanced attention in early sensory processing. AB - Perception of objectively independent events or stimuli as being significantly connected and the associated proneness to perceive meaningful patterns constitute part of the positive symptoms of schizophrenia, which are associated with altered attentional processes in lateralized speech perception. Since perceiving meaningful patterns is to some extent already prevalent in the general population, the aim of the study was to investigate whether the propensity to experience meaningful patterns in co-occurring events and random stimuli may be associated with similar altered attentional processes in lateralized speech perception. Self-reported and behavioral indicators of the perception of meaningful patterns were assessed in non-clinical individuals, along with EEG auditory evoked potentials during the performance of an attention related lateralized speech perception task (Dichotic Listening Test). A greater propensity to perceive meaningful patterns was associated with higher N1 amplitudes of the evoked potentials to the onset of the dichotically presented consonant-vowel syllables, indicating enhanced automatic attention in early sensory processing. The study suggests that more basic mechanisms in how people associate events may play a greater role in the cognitive biases that are manifest in personality expressions such as positive schizotypy, rather than that positive schizotypy moderates these cognitive biases directly. PMID- 29179911 TI - Growth hormone and insulin-like growth factor 1 secretions in eating disorders: Correlations with psychopathological aspects of the disorders. AB - Hormonal alterations in Eating Disorders (ED) may result from the biochemical stress of malnutrition/starvation. The correlations between some hormonal impairments, particularly of the somatotropic axis, and the psychopathological aspects of ED are still undefined. We measured the plasma concentrations of the somatotropic hormone (GH) and the insulin-like growth factor-1 (IGF-1) in 136 patients with various forms of ED, 65 with restricted Anorexia Nervosa (ANR), 19 with bingeing-purging Anorexia Nervosa (ANBP), 12 with purging-non binging Anorexia Nervosa (ANP), 26 with Bulimia Nervosa (BN), 8 with ED not otherwise specified-anorexic type (EDNOS-AN), 7 with ED not otherwise specified-bulimic type (EDNOS-BN) and in 30 healthy controls. Psychological assessment of patients and controls was performed using two outpatient rating scales, the Eating Disorder Inventory-2 (EDI-2) and the Symptom Checklist-90 (SCL-90). Significant negative or positive correlations were observed between GH-IGF-1 concentrations and impairments on several EDI-2 subscales (drive for thinness, body dissatisfaction, interoceptive awareness, sense of ineffectiveness, interpersonal distrust, maturity fear) and on SCL-90 subitems (depression, hostility, obsessivity compulsivity, anxiety), suggesting a possible hormonal modulatory effect on specific aspects of ED psychopathology. PMID- 29179912 TI - Filling the void: a low-cost, high-yield approach to addressing incidental findings in trauma patients. AB - BACKGROUND: Incidental findings are prevalent in imaging but often go unreported to patients. Such unreported findings may present the potential for harm as well as medico-legal ramifications. METHODS: A chart review of trauma patients was undertaken over a year. Systems-based changes were made utilizing our electronic medical record system and our staff protocols to improve the disclosure of clinically relevant incidental findings to patients. RESULTS: During the preintervention period, 674 charts were reviewed. Trauma patients had a rate of incidental findings of 70%, and 36% of patients had clinically relevant incidentals. Rates of follow-up recommendation and disclosure to patients were 22% and 27%, respectively. In the postintervention period, of the 648 charts were reviewed, the rates of a clinically relevant incidental finding were 35%, but the rates of follow-up recommendation and disclosure to patients were 68% and 85%, respectively. CONCLUSION: Incidental findings are more prevalent herein than previously reported. With simple changes and minimal resources, clinically relevant and important improvement in reporting incidental findings can be made to mitigate the harm and medico-legal impact of an incidental finding going unreported.

PMID- 29179915 TI - The impact of the aging population and incidence of cancer on future projections of general surgical workforce needs. AB - BACKGROUND: Assessments of the future general surgery workforce continue to project substantial shortages of general surgeons. The general surgery workforce is targeted currently to maintain a surgeon/population ratio of 6.5-7.5/100,000. METHODS: We examined population and age-associated incidence of cancer to estimate the number of general surgeons needed for initial surgical treatment of the patient with cancer in the year 2035 compared with 2010. We hypothesized that the number of general surgeons needed to provide future cancer care will exceed the projections of available general surgeons based on current training numbers, as well as on population-based ratios alone. RESULTS: The total number of new patients with cancers treated by general surgeons is projected to increase 56% (511,450 in 2010 to 798,070 in 2035). To maintain the same patient census per surgeon, it is estimated that 34,698 general surgeons will be needed. This is an increase of 9,198 over that based on current training numbers and 5,300-7,400 greater than the need projected by population growth alone. CONCLUSION: The analysis supports the hypothesis that an increasing incidence of cancer in the future will exceed the potential capacity of the general surgeon workforce. Regionalization of cancer care may be one solution to projected access issues.

AB - Head-on replication-transcription conflict is especially bitter in bacterial chromosomes, explaining why actively transcribed genes are always co-oriented with replication. The mechanism of this conflict remains unclear, besides the anticipated accumulation of positive supercoils between head-on-conflicting polymerases. Unexpectedly, experiments in bacterial and human cells reveal that head-on replication-transcription conflict induces R-loops, indicating hypernegative supercoiling [(-)sc] in the region - precisely the opposite of that assumed. Further, as a result of these R-loops, both replication and transcription in the affected region permanently stall, so the failure of R-loop removal in RNase H-deficient bacteria becomes lethal. How hyper(-)sc emerges in the middle of a positively supercoiled chromosomal domain is a mystery that requires rethinking of topoisomerase action around polymerases.

PMID- 29179920 TI - Mitochondrial Genome Engineering: The Revolution May Not Be CRISPR-Ized. AB - In recent years mitochondrial DNA (mtDNA) has transitioned to greater prominence across diverse areas of biology and medicine. The recognition of mitochondria as a major biochemical hub, contributions of mitochondrial dysfunction to various diseases, and several high-profile attempts to prevent hereditary mtDNA disease through mitochondrial replacement therapy have roused interest in the organellar genome. Subsequently, attempts to manipulate mtDNA have been galvanized, although with few robust advances and much controversy. Re-engineered protein-only nucleases such as mtZFN and mitoTALEN function effectively in mammalian mitochondria, although efficient delivery of nucleic acids into the organelle remains elusive. Such an achievement, in concert with a mitochondria-adapted CRISPR/Cas9 platform, could prompt a revolution in mitochondrial genome engineering and biological understanding. However, the existence of an endogenous mechanism for nucleic acid import into mammalian mitochondria, a prerequisite for mitochondrial CRISPR/Cas9 gene editing, remains controversial.

AB - BACKGROUND: Prison suicide rates, rate ratios, and associations with prison related factors need clarification and updating. We examined prison suicide rates in countries where reliable information was available, associations with a range of prison-service and health-service related factors, how these rates compared with the general population, and changes over the past decade. METHODS: We collected data for prison suicides in 24 high-income countries in Europe, Australasia, and North America from their prison administrations for 2011-14 to calculate suicide rates and rate ratios compared with the general population. We used meta-regression to test associations with general population suicide rates, incarceration rates, and prison-related factors (overcrowding, ratio of prisoners to prison officers or health-care staff or education staff, daily spend, turnover, and imprisonment duration). We also examined temporal trends. FINDINGS: 3906 prison suicides occurred during 2011-14 in the 24 high-income countries we studied. Where there was breakdown by sex (n=2810), 2607 (93%) were in men and 203 (7%) were in women. Nordic countries had the highest prison suicide rates of more than 100 suicides per 100 000 prisoners apart from Denmark (where it was 91 per 100 000), followed by western Europe where prison suicide rates in France and Belgium were more than 100 per 100 000 prisoners. Australasian and North American countries had rates ranging from 23 to 67 suicides per 100 000 prisoners. Rate ratios, or rates compared with those in the general population of the same sex and similar age, were typically higher than 3 in men and 9 in women. Higher incarceration rates were associated with lower prison suicide rates (b = -0.504, p = 0.014), which was attenuated when adjusting for prison-level variables. There were no associations between rates of prison suicide and general population suicide, any other tested prison-related factors, or differing criteria for defining suicide deaths. Changes in prison suicide rates over the past decade vary widely between countries. INTERPRETATION: Many countries in northern and western Europe have prison suicide rates of more than 100 per 100 000 prisoners per year. Individual-level information about prisoner health is required to understand the substantial variations reported and changes over time.

PMID- 29179936 TI - Clinical relevance of appraisals of persistent psychotic experiences in people with and without a need for care: an experimental study. AB - BACKGROUND: Cognitive models of psychosis propose that appraisals (ie, the interpretation and meaning attributed to experiences) are central to the transition from anomalous experiences to psychotic symptoms. In the Unusual Experiences Enquiry (UNIQUE) study, we investigated the role of appraisals by comparing individuals with persistent psychotic experiences without a need for care with patients and people without psychotic experiences. METHOD: Eligible participants were patients with diagnosed psychotic disorders (clinical group) and adults in the general population with persistent psychotic experiences (non clinical group) and without psychotic experiences (controls). The appraisals of psychotic experiences among people in the non-clinical and clinical groups were assessed by an in-depth interview, and appraisals of anomalous experiences induced by three experimental tasks were compared between all groups. FINDINGS: We recruited 259 participants, 84 in the clinical group, 92 in the non-clinical group, and 83 controls. The clinical group was more likely than the non-clinical group to display paranoid, personalising interpretations of their psychotic experiences (p<0.008; p values are Sidak adjusted to account for multiple testing) and less likely to have normalising (p<0.008) and supernatural (p=0.039) explanations. The clinical group also appraised their psychotic experiences as being more negative, dangerous, and abnormal and less controllable than the non clinical group (all p<0.005), but groups did not differ for attributions of general externality (p=0.44). For experimentally induced anomalous experiences, the clinical group endorsed more threatening appraisals on all tasks than the non clinical group (p<0.003), who did not differ from the control group (p=0.07-0.6). The pattern was similar for ratings of salience, distress, personal relevance, global threat, and incorporation of the induced experiences into participants' own psychotic experiences. INTERPRETATION: We provide robust evidence that the way psychotic experiences are appraised differs between individuals with and without a need for care, supporting cognitive models of psychosis. Specifically, the absence of paranoid and threatening appraisals might protect against persistent psychotic experiences becoming clinically relevant. FUNDING: UK Medical Research Council.

AB - Disaccharides play an important role in survival of anhydrobiotic organisms during extreme environmental conditions. A key protection feature is their capability to form the hydrogen bond (HB) network in a similar fashion as the one made by water. Since various ions also affect the HB network in completely hydrated systems, it is of a great interest to understand how they impact preservation when incorporated in a disaccharide network. To address this, we employ a combination of experimental and modeling techniques to study behavior of multilamellar 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) liposomes freeze dried with sucrose in presence of NaCl or NaH2PO4.H2O at various concentrations (0.01-1M). Differential scanning calorimetry (DSC) was employed in order to determine the cooperative unit size (CUS), the number of lipid molecules that constitute a domain of cooperative motion in the liposome, and the melting temperature (Tm). In the absence of salt CUS was estimated to be 122+/-12, whereas in the presence of NaCl CUS increases more (347+/-34 for c=1M) than for NaH2PO4.H2O (193+/-26 for 1M). When it comes to Tm, the situation is reversed; NaCl induces increase by about 1K, while NaH2PO4.H2O by about 10K. These findings clearly demonstrate how different interaction forces-hydrogen bonding, charge pairing, and van der Waals interactions between acyl chains-affect CUS and Tm. Their interplay and contribution of particular interaction was further analyzed with molecular dynamics (MD) simulations. This analysis demonstrated that the HB network of DMPC and sucrose is partially disrupted in the presence of NaCl ions, and even to a greater extent in the case of NaH2PO4.H2O ions. Notably, H2PO4- ions outcompete and replace the sucrose molecules at the DMPC surface, which in turn alters the nature of the DMPC-surrounding interactions, from a weaker HB dominated to a stronger CP-dominated interaction network.

AB - Mechanical forces are an important contributor to cell fate specification and cell migration during embryonic development in animals. Similarities between embryogenesis and regeneration, particularly with regards to pattern formation and large-scale tissue movements, suggest similarly important roles for physical forces during regeneration. While the influence of the mechanical environment on stem cell differentiation in vitro is being actively exploited in the fields of tissue engineering and regenerative medicine, comparatively little is known about the role of stresses and strains acting during animal regeneration. In this review, we summarize published work on the role of physical principles and mechanical forces in animal regeneration. Novel experimental techniques aimed at addressing the role of mechanics in embryogenesis have greatly enhanced our understanding at scales from the subcellular to the macroscopic - we believe the time is ripe for the field of regeneration to similarly leverage the tools of the mechanobiological research community.

AB - Systemic sclerosis is an autoimmune disease characterized by fibrosis of skin and multiple organs of which the pathogenesis is poorly understood. We studied differentially expressed coding and non-coding genes in relation to systemic sclerosis pathogenesis with a specific focus on antisense non-coding RNAs. Skin biopsy-derived RNAs from 14 early systemic sclerosis patients and six healthy individuals were sequenced with ion-torrent and analyzed using DEseq2. Overall, 4,901 genes with a fold change >1.5 and a false discovery rate <5% were detected in patients versus controls. Upregulated genes clustered in immunologic, cell adhesion, and keratin-related processes. Interestingly, 676 deregulated non coding genes were detected, 257 of which were classified as antisense genes. Sense genes expressed opposite of these antisense genes were also deregulated in 42% of the observed sense-antisense gene pairs. The majority of the antisense genes had a similar effect sizes in an independent North American dataset with three genes (CTBP1-AS2, OTUD6B-AS1, and AGAP2-AS1) exceeding the study-wide Bonferroni-corrected P-value (PBonf < 0.0023, Pcombined = 1.1 * 10-9, 1.4 * 10-8, 1.7 * 10-6, respectively). In this study, we highlight that together with coding genes, (antisense) long non-coding RNAs are deregulated in skin tissue of systemic sclerosis patients suggesting a novel class of genes involved in pathogenesis of systemic sclerosis.

AB - Oxidative stress induced by Reactive Oxygen Species (ROS) was shown to be involved in the pathogenesis of chronic diseases such as cardiovascular pathologies. Particularly, oxidative stress has proved to mediate abnormal platelet function and dysfunctional endothelium-dependent vasodilatation representing a key factor in the progression of ischemic injuries. Antioxidants like carotenoids have been suggested to contribute in their prevention and treatment. Astaxanthin, a xanthophyll carotenoid produced naturally and synthetically, shows interesting antioxidant and anti-inflammatory properties. In vivo studies applying different models of induced ischemia and reperfusion (I/R) injury confirm astaxanthin's protective action after oral or intravenous administration. However, some studies have shown some limitations after oral administration such as low stability, bioavailability and bioefficacy, revealing a need for the implementation of new biomaterials to act as astaxanthin vehicles in vivo. Here, a brief overview of the chemical characteristics of astaxanthin, the carrier systems developed for overcoming its delivery drawbacks and the animal studies showing its potential effect to treat I/R injury are presented.

AB - The skin is the largest organ in the body and plays multiple essential roles ranging from regulating temperature, preventing infection and ultimately defining who we are physically. It is a highly dynamic organ that constantly replaces the outermost cells throughout life. However, when faced with a major injury, human skin cannot restore a significant lesion to its original functionality, instead a reparative scar is formed. In contrast to this, many other species have the unique ability to regenerate full thickness skin without formation of scar tissue. Here we review recent advances in the field that shed light on how the skin cells in regenerative species react to injury to prevent scar formation versus scar forming humans. PMID- 29179951 TI - ROS-dependent Atg4 upregulation mediated autophagy plays an important role in Cd induced proliferation and invasion in A549 cells. AB - Cadmium (Cd) is a toxic heavy metal that is widely used in industry and agriculture. In this study the role of autophagy in Cd-induced proliferation, migration and invasion was investigated in A549 cells. Exposure to Cd (2 MUM) significantly increased reactive oxygen species (ROS) production, induced autophagy and enhanced cell growth, migration and invasion in A549 cells. Western blot analysis showed that the expression of autophagy-related proteins, LC3-II, Beclin-1 and Atg4 and invasion-related protein MMP-9 were upregulated in Cd treated cells. N-acetyl cysteine (NAC) markedly prevented Cd-induced proliferation of A549 cells and the increasing protein level of LC3-II and Atg4. Blocking Atg4 expression by siRNA strongly reduced Beclin-1 and LC3-II protein expression and the number of autophagosome positive cells induced by Cd. Furthermore, Atg4 siRNA increased the number of cells at G0/G1 phase, reduced the number of S and G2/M phase cells, and inhibited Cd-induced cell growth significantly compared with that of Cd-treated Control siRNA cells. 3-MA pretreatment increased the percentage of G0/G1 phase cells, decreased S phase and G2/M phase percentage, and inhibited Cd-induced cell growth remarkably compared with that of only Cd-treated cells. Knocking down Atg4 reduced the number of cells that migrated and invaded through the Matrigel matrix significantly and led to a significant decrease of MMP-9 expression. In addition, in lung tissues of Cd treated BALB/c mice, the increased expression of LC3-II, Beclin-1 and Atg4 were observed. Taken together, our results demonstrated that ROS-dependent Atg4 mediated autophagy plays an important role in Cd-induced cell growth, migration and invasion in A549 cells. PMID- 29179952 TI - Withering syndrome susceptibility of northeastern Pacific abalones: A complex relationship with phylogeny and thermal experience. AB - Population declines in wild and cultured abalones (Haliotis spp.) due to a bacterial disease called withering syndrome (WS) have been documented along the northeastern Pacific Ocean. However, observed differences in species susceptibility to the disease are not well understood. Here, we examined the susceptibility of three temperate abalone species, the cool water (4-14 degrees C) pinto or northern abalone (Haliotis kamtschatkana), the intermediate water (8 18 degrees C) red abalone (H. rufescens), and the warm water (12-23 degrees C) pink abalone (H. corrugata), to experimental WS infection at temperatures facilitating disease proliferation. Mortality data paired with histological and molecular detection of the WS pathogen confirmed that these abalone species exhibit different levels of susceptibility to infection and resistance to WS development ranging from high susceptibility and low resistance in pinto abalone to moderate/low susceptibility and resistance in red and pink abalones. The temperature associated with WS induced mortalities also varied among species: pinto abalone died at the lowest experimental temperature (17.32 +/- 0.09 degrees C), while red abalone died at an intermediate temperature (17.96 +/- 0.16 degrees C), and pink abalone required the highest temperature (18.84 +/- 0.16 degrees C). When data from the current and previous studies were examined, susceptibility to WS was inversely related to phylogenetic distance from white abalone (H. sorenseni), which had the highest susceptibility and lowest resistance of all abalone species tested prior to the current study. These results provide further evidence that an abalone's thermal optima and phylogenetic relationship can determine its susceptibility to WS; species with cool water evolutionary histories are most susceptible to WS and the most susceptible species appear to be closely related. Differences among the thermal ranges of abalone species have broad implications for WS disease dynamics and highlight the importance of understanding the mechanisms governing the abalone-WS relationship in order to properly manage declining abalone populations. PMID- 29179953 TI - Three-dimensional imaging and analysis of entire peripheral nerves after repair and reconstruction. AB - BACKGROUND: We wanted to achieve a three-dimensional (3D), non-destructive imaging and automatic post-analysis and evaluation of reconstructed peripheral nerves without involving cutting and staining processes. NEW METHOD: We used a laboratory-based micro computed tomography system for imaging, as well as a custom analysis protocol. The sample preparation was also adapted in order to achieve 3D images with true micrometer resolution and suitable contrast. RESULTS: Analysis of the acquired tomograms enabled the quantitative assessment of 3D tissue structures, i.e., surface morphology, nerve fascicles, nerve tissue volume, geometry, and vascular regrowth. The resulting data showed significant differences between operated animals and non-operated controls. COMPARISON WITH EXISTING METHODS: Our approach avoids the sampling error associated with conventional 2D visualization approaches and holds promise for automation of the analysis of large series of datasets. CONCLUSIONS: We have presented a potential way for 3D imaging and analysis of entire regenerated nerves non-destructively, paving the way for high-throughput analysis of therapeutic conditions of treating adult nerve injuries. PMID- 29179955 TI - The utility of bedside simulation for training in critical care obstetrics. AB - Over the last 2 decades, the maternal mortality ratio in the United States has doubled from 7.4/100,000 live births in 1986 to 14.5/100,000 today. Despite great advances in health care, increasing rates of maternal morbidity and mortality in the United States have prompted calls to action to reverse this disturbing trend. Assisted reproductive technology has allowed women to delay childbearing to more advanced ages, resulting in a greater number of pregnancies complicated by one or more of the diseases associated with aging, such as cardiovascular disease, cancer, type 2 diabetes, and hypertension. The obesity epidemic, increasing rates of chronic diseases affecting pregnancy, steadily rising cesarean delivery rate with resulting complications, and medical advances allowing women with rare, but serious diseases to conceive contribute to rising maternal morbidity and mortality rates. Obstetric critical care simulation training may result in improved multidisciplinary teamwork and patient outcomes; and fewer medical and communication errors.

AB - Extracorporeal membrane oxygenation (ECMO) can provide respiratory support (VV ECMO) or both respiratory and circulatory support (VA-ECMO). The use of ECMO has increased dramatically as a result of simpler technology. No level I evidence is yet available reflecting improved outcomes with ECMO. The use of this technology during pregnancy may be indicated in very select cases and should be delivered in centers with dedicated ECMO specialized units.

In this review, we highlight pertinent clinical features of CAPS so that obstetricians will be able to recognize and treat the condition. PMID- 29179954 TI - Universal health coverage and intersectoral action for health: key messages from Disease Control Priorities, 3rd edition. AB - The World Bank is publishing nine volumes of Disease Control Priorities, 3rd edition (DCP3) between 2015 and 2018. Volume 9, Improving Health and Reducing Poverty, summarises the main messages from all the volumes and contains cross cutting analyses. This Review draws on all nine volumes to convey conclusions. The analysis in DCP3 is built around 21 essential packages that were developed in the nine volumes. Each essential package addresses the concerns of a major professional community (eg, child health or surgery) and contains a mix of intersectoral policies and health-sector interventions. 71 intersectoral prevention policies were identified in total, 29 of which are priorities for early introduction. Interventions within the health sector were grouped onto five platforms (population based, community level, health centre, first-level hospital, and referral hospital). DCP3 defines a model concept of essential universal health coverage (EUHC) with 218 interventions that provides a starting point for country-specific analysis of priorities. Assuming steady-state implementation by 2030, EUHC in lower-middle-income countries would reduce premature deaths by an estimated 4.2 million per year. Estimated total costs prove substantial: about 9.1% of (current) gross national income (GNI) in low income countries and 5.2% of GNI in lower-middle-income countries. Financing provision of continuing intervention against chronic conditions accounts for about half of estimated incremental costs. For lower-middle-income countries, the mortality reduction from implementing the EUHC can only reach about half the mortality reduction in non-communicable diseases called for by the Sustainable Development Goals. Full achievement will require increased investment or sustained intersectoral action, and actions by finance ministries to tax smoking and polluting emissions and to reduce or eliminate (often large) subsidies on fossil fuels appear of central importance. DCP3 is intended to be a model starting point for analyses at the country level, but country-specific cost structures, epidemiological needs, and national priorities will generally lead to definitions of EUHC that differ from country to country and from the model in this Review. DCP3 is particularly relevant as achievement of EUHC relies increasingly on greater domestic finance, with global developmental assistance in health focusing more on global public goods. In addition to assessing effects on mortality, DCP3 looked at outcomes of EUHC not encompassed by the disability adjusted life-year metric and related cost-effectiveness analyses. The other objectives included financial protection (potentially better provided upstream by keeping people out of the hospital rather than downstream by paying their hospital bills for them), stillbirths averted, palliative care, contraception, and child physical and intellectual growth. The first 1000 days after conception are highly important for child development, but the next 7000 days are likewise important and often neglected.

AB - Alpha-methylacyl-CoA racemase (AMACR) expression has been demonstrated in several normal tissues and in diverse types of carcinoma. Our aim was to analyze the immunohistochemical expression of AMACR in the sequence-progression of colonic cancer. We studied 237 cases, including samples of normal mucosa of the colon, adenomas with different degrees of dysplasia, colonic carcinomas, lymph nodes and liver metastases of colonic carcinomas. A scale of intensity and percentage of expression was used to analyze the AMACR immunohistochemical profile. The expression was nearly absent in samples of normal mucosa, increased in both adenomas and carcinomas, decreased in lymph node metastases but was significantly increased in liver metastases.

PMID- 29179962 TI - The spectrum of glomerular disease between the years 2003 and 2015 in Columbia: A review of 12,613 cases. AB - BACKGROUND: The prevalence of glomerular disease (GD) varies according to the different socio-demographic characteristics of each population. For the first time we present the prevalence of the different forms of GD among patients from several different areas of Columbia. METHODS: Data from 12,613 renal biopsies studied at our University Hospital between 2003 and 2015 was reviewed. Pathology results were classified according to a list of renal diseases proposed by various authors. RESULTS: Focal segmental glomerulosclerosis was present in 22%, IgA disease in 21%, Lupus nephritis in 17%, membranous glomerulonephritis in 13% and thin basal membrane disease in 9%. CONCLUSIONS: This study confirms that focal segmental glomerulosclerosis and IgA disease are the most prevalent GDs found in Columbian patients. This is the first study to analyze GDs in a Columbian population and we recommend that a national registry system be created to collect comprehensive information from future research. PMID- 29179963 TI - [Protocol for the study of bone tumours and standardization of pathology reports]. AB - Primary bone neoplasms represent a rare and heterogeneous group of mesenchymal tumours. The prevalence of benign and malignant tumours varies; the latter (sarcomas) account for less than 0.2% of all malignant tumours. Primary bone neoplasms are usually diagnosed and classified according to the criteria established and published by the World Health Organization (WHO 2013). These criteria are a result of advances in molecular pathology, which complements the histopathological diagnosis. Bone tumours should be diagnosed and treated in referral centers by a multidisciplinary team including pathologists, radiologists, orthopedic surgeons and oncologists. We analyzed different national and international protocols in order to provide a guide of recommendations for the improvement of pathological evaluation and management of bone tumours. We include specific recommendations for the pre-analytical, analytical, and post analytical phases, as well as protocols for gross and microscopic pathology.

AB - Pseudomyogenic hemangioendothelioma, also called epithelioid sarcoma-like hemangioendothelioma, is a rare, vascular neoplasm usually with indolent behaviour. It was introduced in the latest World Health Organization (WHO) Classification of Tumours of Soft Tissue. We report a case of a 45 year-old patient presenting with a localized, palpable and slightly painful lesion in the left arm. Histologically it consisted of fascicles of spindle and epithelioid cells with ample eosinophilic cytoplasm, without nuclear pleomorphism or significant mitotic activity. Tumour cells showed diffuse expression for cytokeratin AE1/AE3, CD31 and FLI1, intact expression for INI1 and negativity for CD34. We describe the clinical, histological, molecular and immunohistochemical features of pseudomyogenic hemangioendothelioma and review the pertinent literature.

AB - The coexistence of two or more tumours in the same patient is unusual, but even rarer is the metastasis of one tumour to another. Most reports are based on evidence from autopsies; very few refer to surgical specimens. The most common primary tumour is pulmonary carcinoma and most frequent metastatic tumour is renal clear cell carcinoma. We present the case of a 54 year-old female with a past history of infiltrating ductal carcinoma of the breast with metastases in lung, lymph nodes and bone. Three months previously to her referral to us, she had developed a renal mass and underwent nephrectomy. Histopathology revealed a renal chromophobe cell carcinoma with intratumoral breast cancer metastasis. We describe the histopathological, immunohistochemical and molecular features and review the recent literature. PMID- 29179968 TI - [Genetic analysis of a family with Von Hippel-Lindau syndrome]. AB - Von Hippel-Lindau syndrome (VHL) is an autosomal dominant inherited disease associated with mutations in the VHL tumour suppressor gene located on chromosome 3p25. VHL is characterized by the development of multiple malignant and benign tumours in the central nervous system and internal organs, including liver, pancreas and the adrenal gland. More than 823 different mutations of the VHL gene have currently been identified. In the present study we describe the case of a family affected by VHL treated at the University Hospital of La Ribera and the results of the genetic analysis of three relatives, identifying the mutation R167G in exon 3 of VHL gene as the cause of VHL syndrome in this family. PMID- 29179970 TI - An interproximal model to determine the erosion-protective effect of calcium silicate, sodium phosphate, fluoride formulations. AB - OBJECTIVES: Previous work has shown the effectiveness of a newly developed interproximal model to differentiate between the amount of remineralization caused by toothpastes used with or without a dual-phase gel treatment system containing calcium silicate, sodium phosphate salts and fluoride to repair acid softened enamel. The aim of this study was to utilize the same interproximal model to identify how effective calcium silicate phosphate toothpastes are at reducing surface softening in the early stages of erosion. The model was also used to identify the effect of increasing the frequency of acid exposure on the reduction in surface hardness. METHODS: Human enamel specimens were prepared and mounted in an interproximal face-to-face arrangement and exposed to a cycling regime of whole human saliva, treatment, artificial saliva and 1% citric acid pH 3.75. Specimens were measured by surface microhardness at baseline and after three and seven days. The frequency of acid exposure was increased from 2 to 4 cycles a day for the second part of the study. RESULTS: The results showed that specimens treated with the calcium silicate phosphate toothpastes softened less than those treated with control fluoridated or non-fluoride toothpastes at each time point and following an increase in the frequency of acid exposure. SIGNIFICANCE: This work has demonstrated how an interproximal model can also be successfully used to determine differences in the erosion protection of various treatments as well as determining how they perform when the frequency of acid exposure is increased. PMID- 29179969 TI - [Detection of herpes virus and human enterovirus in pathology samples using low density arrays]. AB - Despite the frequency of infections with herpesviridae family, only eight subtypes affect humans (Herpex Simplex Virus types 1 and 2, Varicella Zoster Virus, Epstein-Barr Virus, Citomegalovirus and Human Herpes Virus types 6, 7 and 8). Amongst enteroviruses infections, the most important are Poliovirus, Coxackievirus and Echovirus. Symptoms can vary from mild to severe and early diagnosis is of upmost importance. Nowadays, low-density arrays can detect different types of viruses in a single assay using DNA extracted from biological samples. We analyzed 70 samples of formalin-fixed and paraffin-embedded tissue, searching for viruses (HSV-1, HSV-2, VZV, CMV, EBV, HHV-6, HHV-7 y HHV-8, Poliovirus, Echovirus and Coxsackievirus) using the kit CLART(r) ENTHERPEX. Out of the total of 70 samples, 29 were positive for viral infection (41.43%), and only 4 of them showed cytopathic effect (100% correlation between histology and the test). 47.6% of GVHD samples were positive for virus; 68.75% of IBD analyzed showed positivity for viral infection; in colitis with ulcers (neither GVHD nor IBD), the test was positive in 50% of the samples and was also positive in 50% of ischemic lesions. The high sensitivity of the technique makes it a useful tool for the pathologist in addition to conventional histology-based diagnosis, as a viral infection may affect treatment. PMID- 29179971 TI - Dentin bonding systems: From dentin collagen structure to bond preservation and clinical applications. AB - OBJECTIVES: Efforts towards achieving durable resin-dentin bonds have been made for decades, including the understanding of the mechanisms underlying hybrid layer (HL) degradation, manufacturing of improved adhesive systems, as well as developing strategies for the preservation of the HL. METHODS: This study critically discusses the available peer-reviewed research concerning the formation and preservation of the HL, the mechanisms that lead to the degradation of the HL as well as the strategies to prevent it. RESULTS: The degradation of the HL occurs through two main mechanisms: the enzymatic degradation of its collagen fibrils, and the leaching of the resin from the HL. They are enabled by residual unbound water between the denuded collagen fibrils, trapped at the bottom of the HL. Consequently, endogenous dentinal enzymes, such as the matrix metalloproteinases (MMPs) and cysteine cathepsins are activated and can degrade the denuded collagen matrix. Strategies for the preservation of the HL over time have been developed, and they entail the removal of the unbound water from the gaps between the collagen fibrils as well as different modes of silencing endogenous enzymatic activity. SIGNIFICANCE: Although there are many more hurdles to be crossed in the field of adhesive dentistry, impressive progress has been achieved so far, and the vast amount of available research on the topic is an indicator of the importance of this matter and of the great efforts of researchers and dental material companies to reach a new level in the quality and longevity of resin-dentin bonds. PMID- 29179972 TI - Cross-linking effect on dentin bond strength and MMPs activity. AB - OBJECTIVE: The objectives of the study were to evaluate the ability of a 1-ethyl 3 (3-dimethylaminopropyl) carbodiimide (EDC)-containing primer to improve immediate bond strength of either self-etch or etch-and-rinse adhesive systems and to stabilize the adhesive interfaces over time. A further objective was to investigate the effect of EDC on the dentinal MMPs activity using zymographic analysis. METHODS: Freshly extracted molars (n=80, 20 for each group) were selected to conduct microtensile bond strength tests. The following groups were tested, immediately or after 1-year aging in artificial saliva: G1: Clearfil SE (CSE) primer applied on unetched dentin, pretreated with 0.3M EDC water-solution for 1min and bonded with CSE Bond; G2: as G1 but without EDC pre-treatment; G3: acid-etched (35% phosphoric-acid for 15s) dentin pretreated with 0.3M EDC, then bonded with XP Bond (XPB); Group 4 (G4): as G3 without EDC pre-treatment. Further, gelatinase activity in dentin powder treated with CSE and XPB with and without EDC pre-treatment, was analyzed using gelatin zymography. RESULTS: The use of 0.3M EDC-containing conditioner did not affect the immediate bond strength of XPB or CSE adhesive systems (p>0.05), while it improved the bond strength after 1year of aging (p<0.05). Pre-treatment with EDC followed by the application of CSE resulted in an incomplete MMPs inactivation, while EDC pretreatment followed by the application of XPB resulted in an almost complete inactivation of dentinal gelatinases. SIGNIFICANCE: The MUTBS and zymography results support the efficacy of EDC over time and reveal that changes within the dentin matrix promoted by EDC are not adhesive-system-dependent. PMID- 29179973 TI - Mechanism of bioactive molecular extraction from mineralized dentin by calcium hydroxide and tricalcium silicate cement. AB - OBJECTIVES: The objective of the present study was to elucidate the mechanism of bioactive molecule extraction from mineralized dentin by calcium hydroxide (Ca(OH)2) and tricalcium silicate cements (TSC). METHODS AND RESULTS: Transmission electron microscopy was used to provide evidence for collagen degradation in dentin surfaces covered with Ca(OH)2 or a set, hydrated TSC for 1 3 months. A one micron thick collagen degradation zone was observed on the dentin surface. Fourier transform-infrared spectroscopy was used to identify increases in apatite/collagen ratio in dentin exposed to Ca(OH)2. Using three-point bending, dentin exposed to Ca(OH)2 exhibited significant reduction in flexural strength. Using size exclusion chromatography, it was found that the small size of the hydroxyl ions derived from Ca(OH)2 enabled those ions to infiltrate the intrafibrillar compartment of mineralized collagen and degrade the collagen fibrils without affecting the apatite minerals. Using ELISA, TGF-beta1 was found to be extracted from dentin covered with Ca(OH)2 for 3 months. Unlike acids that dissolve the mineral component of dentin to release bioactive molecules, alkaline materials such as Ca(OH)2 or TSC released growth factors such as TGF-beta1 via collagen degradation. SIGNIFICANCE: The bioactive molecule extraction capacities of Ca(OH)2 and TSC render these dental materials excellent for pulp capping and endodontic regeneration. These highly desirable properties, however, appear to be intertwined with the untoward effect of degradation of the collagen matrix within mineralized dentin, resulting in reduced flexural strength. PMID- 29179974 TI - Glycaemic responses in Asian and non-Asian people with type 2 diabetes initiating insulin glargine 100 units/mL: A patient-level pooled analysis of 16 randomised controlled trials. AB - AIMS: To compare outcomes between Asian and non-Asian patients with type 2 diabetes (T2D) inadequately controlled on oral antidiabetic drugs (OADs) initiating insulin glargine 100 units (U)/mL (Gla-100) in randomised controlled clinical trials. METHODS: Post hoc analysis of patient-level data (Asian n = 235; non-Asian n = 3351) from 16 trials. RESULTS: At baseline, Asian patients were younger with lower body mass index (BMI), fasting C-peptide, and fasting plasma glucose (FPG) than non-Asian patients (all P < .001). Asian patients had a higher mean glycosylated haemoglobin (HbA1c) at Week 24 and less reduction in HbA1c from baseline (7.4% vs. 7.2%; -1.3% vs. -1.6%, respectively; P = .0001), and were less likely to achieve HbA1c <7.0% (40% vs. 47%; P = .002) than non-Asian patients. Reductions in FPG and rates of hypoglycaemia were similar between Asian and non Asian patients. Asian patients had less weight gain than non-Asian patients (+1.3 vs. +1.9 kg, respectively, P = .013). CONCLUSIONS: In our post hoc meta-analysis, Gla-100 effectively lowers HbA1c and FPG in Asian patients with T2D uncontrolled on OADs with similar incidence of hypoglycaemia and less absolute weight gain compared with non-Asian patients. At a similar FPG reduction, fewer Asian patients achieved HbA1c target <7.0%, suggesting that prandial glucose needs to be addressed.

AB - Hypothyroidism causes an imbalance in antioxidant and pro-oxidants criteria in the brain and enhances the concentration of reactive oxygen species (ROS), and neuronal damage has been observed following an excessive ROS. The main purpose of this study was to examine the preventive effect of vitamin C on hypothyroidism associated neuronal damage in the hippocampus of neonatal and juvenile rats. Pregnant rats after delivery of their pups were randomly divided into four groups and treated with (1) normal drinking water as a control group, (2) Propylthiouracil (PTU) 0.005% added to drinking water, (3-, 4) PTU + Vit C 10 mg/ kg and PTU + Vit C 100 mg/ kg to drinking water. Treatment was carried out during rat's lactation period until to the postnatal day (PND) 60. To assess the histological and stereological changes that occur in this study, brains of 5 male pups were extracted. The number of dark neurons and apoptotic cells in the hippocampal sub-regions of PTU group was significantly greater than the control group's hippocampal sub-regions. In addition, hypothyroidism induced a reduction in the hippocampal volume and increased the numerical density and the total amount of dark neurons. The vitamin C only dose of 100 mg/kg significantly reduced the number of dark neurons and apoptotic cells (P < 0.01) and considerably weakened the influence of hypothyroidism on the volume reduction of the hippocampus (P < 0.05). The current study suggested that vitamin C administration has a possibility to prevent hippocampal neuronal damage caused by neonatal and juvenile hypothyroidism in rats. PMID- 29179977 TI - Altered O-glycosylation is associated with inherent radioresistance and malignancy of human laryngeal carcinoma. AB - Radioresistance (inherent or acquired) remains a major obstacle affecting the clinical outcome of radiotherapy for laryngeal carcinoma. Results from our laboratory and other groups suggest that aberrant glycosylation contributes to cancer acquired radioresistance. However, the role of glycosylation in inherent radioresistance of laryngeal carcinoma has not been fully uncovered. In this study, we investigated the glycan profiling of the inherent radioresistant (Hep 2max) and radiosensitive (Hep-2min) cell lines using lectin microarray analysis. The results revealed that the radioresistant cell line Hep-2max presented higher core 1-type O-glycans than the sensitive one. Further analysis of the O-glycan regulation by benzyl-alpha-GalNAc application in Hep-2max cells showed partial inhibition of the O-glycan biosynthesis and increased radiosensitivity. In addition, core 1 beta1, 3-galactosyltransferase (C1GALT1) overexpression in Hep 2min cells enhanced cell migration, invasion, and radioresistance. Conversely, knockdown of C1GALT1 in Hep-2max cells was able to suppress these malignant phenotypes. Moreover, mechanistic investigations showed that C1GALT1 modified the O-glycans on integrin beta1 and regulated its activity. The glycosylation mediated radioresistance was further inhibited by anti-integrin beta1 blocking antibody. Importantly, we also observed that core 1-type O-glycans expression was correlated with advanced tumor stage, metastasis, and poor survival of laryngeal carcinoma patients. These findings suggest that altered O-glycosylation can lead to the inherent radioresistance and progression, and therefore may be important for enhancing the efficacy of radiotherapy in laryngeal carcinoma. PMID- 29179978 TI - Assessment of the extent of pituitary macroadenomas resection in immediate postoperative MRI. AB - OBJECTIVE: To evaluate if it is possible to determine the extent of pituitary macroadenomas resection in the immediate postoperative pituitary magnetic resonance imaging (MRI). MATERIAL AND METHODS: MRI of patient with pituitary macroadenomas from January 2010 until October 2014 were reviewed. Those patients who had diagnostic MRI, immediate post-surgical MRI and at least one MRI control were included. We evaluate if the findings between the immediate postsurgical MRI and the subsequent MRI were concordant. Cases which didn't have evolutionary controls and those who were reoperation for recurrence were excluded. The degree of tumor resection was divided into groups: total resection, partial resection and doubtful. All MRI studies were performed on a1.5T machine following the same protocol sequences for all cases. One morphological part, a dynamic contrast iv and late contrast part. RESULTS: Of the 73 cases included, immediate postoperative pituitary MRI was interpreted as total resection in 38 cases and tumoral rest in 28 cases, uncertainty among rest or inflammatory changes in 7 cases. Follow- up MRI identified 41 cases total resection and tumoral rest in 32. Sensitivity and specificity of 0.78 and 0.82 and positive and negative predictive value (PPV and NPV) 0.89 and 0.89 respectively were calculated. CONCLUSION: Immediate post-surgery pituitary MRI is useful for assessing the degree of tumor resection and is a good predictor of the final degree of real resection compared with the following MRI studies.

AB - Preservation or regeneration of the papilla has always been a challenge around consecutive implants or with implants next to teeth, and many studies have evaluated the papilla's behaviour and patterns based on surgical technique and prosthetic design, though evidence about its behaviour around zirconia implants is scarce. The aim of this study was to evaluate papilla behaviour between implants and teeth (tooth-implant group) and between consecutive implants (implant-implant group). Ninety patients with 122 zirconia implants (Straumann(r) PURE Ceramic Implant) were examined at the one-year follow up. We measured the effect of the distance: first from the base of the contact point of the crowns to the contact with bone at the implant site (D1); secondly, to the contact with the bone at the neighbouring tooth or implant site (D2); and thirdly on the papillary deficit (D3). In both the tooth-implant group and the implant-implant group, D1 and D2 correlated significantly with the papillary deficit (D3), whereas D2 was the major determinant factor (Spearman's rho=0.60). In both groups, when D1 and D2 were <6mm, the papilla was present every time. The papillary deficit was significantly greater in the tooth-implant group than in the implant-implant group (p=0.048). We conclude that the ideal distance from the base of the contact point to the bone contact at the implant and to the bone contact at the adjacent tooth in both groups is <6mm. The height of the bone on the teeth adjacent to implants has a significant impact on that of the papilla.

PMID- 29179982 TI - Paediatric invasive pneumococcal disease on the island of Gran Canaria: 16-year prospective study (2001-2016). AB - OBJECTIVES: To calculate the incidence of invasive pneumococcal disease (IPD) in the paediatric population of Gran Canaria (Spain), its clinical and epidemiological characteristics, serotype distribution, antibiotic resistance, and variations in these variables before and after the introduction of the PCV13 vaccine. METHODS: Prospective hospital-based study including all patients (190) aged 0-14 years admitted with confirmed IPD between January 2001-May 2010 (152 cases) and June 2010-December 2016 (38 cases). Patients were divided into 3 age groups (<2 years; 2-5 years; and >5 years). Clinical symptoms were mutually exclusively classified as meningitis, bacteraemic pneumonia, pleural effusion (PE), empyema or bacteraemia without a focus. RESULTS: Most cases occurred in boys (59.47%), during autumn-winter (65.79%), in children aged <2 years (55.79%) and with mean age increasing from the pre-PCV13 to the post-PCV13 period (2.5 vs 3.1 years). Incidence between periods reduced by 66.4% (p<0.001): from 13.1/100,000 to 4.4/100,000. PEs (3.9% vs 18.4%, p<0.005) and empyemas (1.5% vs 16.7%, p=NS) increased in the post-PCV13 period whereas all other symptoms decreased, although this was not statistically significant. Vaccine serotypes (77% vs 40.6%, p=0.000), particularly serotypes 19A (23.9% vs 12.5%) and 14 (14.2% vs 9.4%), as well as erythromycin resistance (57.2% vs 7.9%, p=0.000) decreased in the post-PCV13 period. CONCLUSION: IPD incidence, vaccine serotypes and erythromycin resistance decreased in the post-PCV13 period whereas PEs increased.

AB - INTRODUCTION: The aim of this study was to analyze the presence of antibodies against both Yamagata and Victoria influenza B lineages and to check the response after seasonal trivalent vaccination. MATERIALS AND METHODS: Haemagglutination inhibition assays were performed with pre-and post-vaccination serum samples from 174 individuals >=65 years of age vaccinated with seasonal trivalent influenza vaccines during the 2006-2007, 2008-2009, 2009-2010 and 2010-2011 vaccine campaigns. RESULTS: 33.9% of individuals showed pre-vaccine protective antibodies (>=1/40) against B/Yamagata lineage and 41.4% against B/Victoria lineage. The annual trivalent vaccine induced significant homologous seroconversion in 14 35.6% of individuals in each vaccine campaign. CONCLUSIONS: The population >=65 years has low-moderate seroprotection against B influenza lineages. Trivalent vaccination induced a slight increase of seroprotection. The trivalent vaccine should be administered to all individuals >=65 years in all vaccine campaigns. PMID- 29179985 TI - Cardiac CD68+ and stabilin-1+ macrophages in wound healing following myocardial infarction: From experiment to clinic. AB - Myocardial infarction (MI) remains the leading cause of mortality and morbidity throughout the world. Macrophages are key innate immune cells that play a significant role in transition from the inflammatory to the regenerative phase during wound healing following MI. The scavenger receptor stabilin-1 is one of the most interesting macrophage biomarkers. This receptor contributes to wound healing, angiogenesis, and tissue remodeling. We suggested a research protocol using macrophage biomarkers to study the cellular basis of cardiac remodeling and healing in patients with acute MI. The purpose of the research was to translate experimental knowledge regarding macrophage subsets and their biomarkers in post infarction myocardial regeneration into results observed in clinical settings. The study included 41 patients with fatal MI type 1. All patients were divided into four groups according to the timeline of MI histopathology. In addition to routine histopathological analysis, macrophage infiltration was assessed by immunohistochemistry. We used CD68 as a marker for the cells of the macrophage lineage and stabilin-1 as an M2-like macrophage biomarker. The number of CD68+ and stabilin-1+ macrophages in the infarct area increased and peaked in the regenerative phase and did not decrease in the late stage of MI. In the peri infarct area, the number of CD68+ macrophages increased in the inflammatory phase, peaked during the reparative phase, and did not decrease in the late phase, while the number of stabilin-1+ macrophages increased in the regenerative phase and remained unchanged. Additionally, in the reparative phase, we observed increase in the number of CD68+ and stabilin-1+ macrophages in the non-infarct area. The research protocol suggested allowed us to translate experimental knowledge regarding macrophage subsets and their biomarkers in post-infarction myocardial regeneration into clinical data. Taken together, these results demonstrated biphasic cardiac macrophage response following acute MI somewhat similar to that in a murine model. The increase in stabilin-1+ macrophage infiltration noticed in the myocardium during the regenerative phase and the strong positive correlation between the number of these cells and timeline of MI histopathology enabled us to propose stabilin-1 as a diagnostic macrophage biomarker in myocardium wound healing in patients with acute MI. PMID- 29179986 TI - Natural killer cell metabolism. AB - Natural killer (NK) cells are a critical component in the innate immune response against disease. NK cell function is tightly regulated by specific cytokine and activation/inhibitory receptor signalling, leading to diverse effector responses. Like all living cells, energy metabolism is a fundamental requirement for NK cell activation and survival. There is growing evidence that distinct functional profiles of NK cells are determined by alterations to cellular metabolic pathways. In this review, we summarise current literature that has explored NK cell metabolism to provide insight into how metabolic regulation controls NK cell function. We focus on metabolism pathways induced by different NK cell stimuli, metabolic regulatory proteins, and nutrient and hormonal levels in health and disease which impact on NK cell metabolic and functional activity. PMID- 29179987 TI - Identification of genes involved in the four stages of colorectal cancer: Gene expression profiling. AB - BACKGROUND: Colorectal cancer (CRC) is a common cancer with high morbidity and mortality. However, its molecular mechanism is not clear, nor the genes related to CRC stages. METHODS: Gene expression data in CRC and healthy colorectal tissues were obtained from gene expression omnibus. Limma package was used to identify the differentially expressed genes (DEGs) between control and CRC (stage I, II, III, and IV), obtaining 4 DEG sets. VennPlex was utilized to find all DEGs and intersection DEGs. Functional interactions between all DEGs and protein protein interactions (PPIs) between intersection DEGs were analyzed using ReactomeFIViz and STRING, respectively, and networks were visualized. Known CRC related genes were down-loaded from Comparative Toxicogenomics Database and mapped to PPI network. RESULTS: Totally, 851, 760, 729, and 878 DEGs were found between control and CRC stage I, II, III, and IV, respectively. Taken together, 1235 DEGs were found, as well as 128 up-regulated intersection DEGs, 365 down regulated intersection DEGs, and 0 contra-regulated DEG. A functional interaction network of all DEGs and a PPI network of intersection DEGs were constructed, in which CDC20, PTTG1, and MAD2L1 interacted with BUB1B; UGT2B17 interacted with ADH1B; MCM7 interacted with MCM2. BUB1B, ADH1B, and MCM2 were known CRC-related genes. Gradually upregulated expressions of CDC20, PTTG1, MAD2L1, UGT2B17, and MCM7 in stage I, II, III, and IV CRC were confirmed by using quantitative PCR. Besides, up-regulated intersection DEGs enriched in pathways about Cell cycle, DNA replication, and p53 signaling. CONCLUSION: CDC20, PTTG1, MAD2L1, UGT2B17, and MCM7 might be CRC stage-related genes. PMID- 29179988 TI - Label-free monitoring of ambient oxygenation and redox conditions using the photodynamics of flavin compounds and transient state (TRAST) spectroscopy. AB - Transient state (TRAST) monitoring can determine population dynamics of long lived, dark transient states of fluorescent molecules, detecting only the average fluorescence intensity from a sample, when subject to different excitation pulse trains. Like Fluorescence Correlation Spectroscopy (FCS), TRAST unites the detection sensitivity of fluorescence with the environmental sensitivity of long lived non-fluorescent states, but does not rely on detection of stochastic fluorescence fluctuations from individual molecules. Relaxed requirements on noise suppression, detection quantum yield and time-resolution of the instrument, as well as on fluorescence brightness of the molecules studied, make TRAST broadly applicable, opening also for investigations based on less bright, auto fluorescent molecules. In this work, we applied TRAST to study the transient state population dynamics within the auto-fluorescent coenzymes flavin adenine dinucleotide (FAD) and flavin-mononucleotide (FMN). From the experimental TRAST data, we defined state models, and determined rate parameters for triplet state and redox transitions within FMN and FAD, stacking and un-stacking rates of external redox active quenching agents and by the adenine moiety of FAD itself. TRAST experiments were found to be well capable to resolve these transitions in FMN and FAD, and to track how the transitions are influenced by ambient oxygenation and redox conditions. This work demonstrates that TRAST provides a useful tool to follow local oxygenation and redox conditions via FMN and FAD fluorescence, and forms the basis for measurements on flavo-proteins and of redox and metabolic conditions in more complex environments, such as in live cells. PMID- 29179989 TI - Examination of biochemical and biological activities of Bothrops jararaca (Serpentes: Viperidae; Wied-Neuwied 1824) snake venom after up to 54 years of storage. AB - The number of snakes donated to the Brazilian Instituto Butantan has been decreasing in the past 10 years. This circumstance motivated us to compare the properties of five venom pools of Bothrops jararaca snake stored for up to 54 years. Results showed differences among venom pools regarding enzymatic and other biological activities, such as caseinolytic, phospholipase A2, hemorrhagic and coagulant activities, as well as antigenicity. Protein content, reverse-phase chromatographic profile, and immunorecognition by commercial Bothrops antivenom were comparable for all venom pools, although lethality of the most recent preparations was higher. Since the lowest functional activities did not always correspond to older venoms, differences among venom pools used for antivenom production during the period 1963-2008 may correlate with the different proportions of venoms from different localities used in their generation, rather than to long-term storage. We conclude that B. jararaca venoms properly stored for long periods of time retain their structural and pharmacological activities, thus representing useful materials for scientific research and antivenom production. PMID- 29179990 TI - Snakebite by Micrurus averyi (Schmidt, 1939) in the Brazilian Amazon basin: Case report. AB - Micrurus snakes, commonly known as coral snakes, are responsible for 0.4% of the snakebites envenomings in Brazil. In this report, we describe a case of envenoming by Micrurus averyi, the black-headed coral snake, recorded in the western Brazilian Amazon. To the best of our knowledge, this is the first published case perpetrated by this species. The major complaint of the patient was an intense local pain and paresthesia. Examination of the bite site revealed edema extending from the left foot up the left leg that was accompanied by erythema involving the foot and distal third of the leg. Systemic signs at admission included nausea and drooling. The patient was treated with 100 mL of coral snake antivenom and intravenous analgesics (dipyrone) and was discharged 48 h post-admission with no complaints. The patient showed more intense local edema than that generally described in several other cases of Micrurus bites in Brazil.

PMID- 29179993 TI - Dissociable effects of reward and expectancy during evaluative feedback processing revealed by topographic ERP mapping analysis. AB - Evaluative feedback provided during performance monitoring (PM) elicits either a positive or negative deflection ~250-300ms after its onset in the event-related potential (ERP) depending on whether the outcome is reward-related or not, as well as expected or not. However, it remains currently unclear whether these two deflections reflect a unitary process, or rather dissociable effects arising from non-overlapping brain networks. To address this question, we recorded 64-channel EEG in healthy adult participants performing a standard gambling task where valence and expectancy were manipulated in a factorial design. We analyzed the feedback-locked ERP data using a conventional ERP analysis, as well as an advanced topographic ERP mapping analysis supplemented with distributed source localization. Results reveal two main topographies showing opposing valence effects, and being differently modulated by expectancy. The first one was short lived and sensitive to no-reward irrespective of expectancy. Source-estimation associated with this topographic map comprised mainly regions of the dorsal anterior cingulate cortex. The second one was primarily driven by reward, had a prolonged time-course and was monotonically influenced by expectancy. Moreover, this reward-related topographical map was best accounted for by intracranial generators estimated in the posterior cingulate cortex. These new findings suggest the existence of dissociable brain systems depending on feedback valence and expectancy. More generally, they inform about the added value of using topographic ERP mapping methods, besides conventional ERP measurements, to characterize qualitative changes occurring in the spatio-temporal dynamic of reward processing during PM.

PMID- 29179996 TI - Combined effect of gestational stress and postpartum stress on maternal care in rats. AB - Variations in maternal care in the rat influence the development of individual differences in behavioral and endocrine responses to stress. This study aimed to examine the interaction between intragastric intubation during late gestation and postpartum stress, induced by pup separation, on maternal behavior and on dams' emotional state and HPA axis function. Rats received intragastric intubation of water on days 12-20 of gestation or remained untreated in their home cage (naive dams). Pup separation was used as a model of postpartum stress. The procedure consisted of a daily separation of the dam from its litter for 3h from PND 3 until PND 15. Pup separation was carried out in both naive and intubated dams. The behavioral results indicate that the association of these two stressors significantly decreased arched-back nursing (ABN) and licking and grooming (LG), behaviors considered important parameters to discriminate the high quality of maternal care. Moreover, dams that received both stressors displayed less nest building and blanket nursing behaviors; no effect on the frequency of passive and total nursing was recorded. The analysis of single effects on ABN and LG, revealed that dams that underwent gestational stress induced by intragastric intubation displayed less LG, but ABN was overall unchanged. On the contrary, pup separation stress significantly increased ABN and LG upon reunion of naive dams with their pups. Treatments per se or the association of both induced modest changes in plasma levels of allopregnanolone and corticosterone that likely did not influence maternal care. These data show that the association of a mild stress during gestation with an unfavorable experience after parturition had a significant impact on maternal care. This effect seems independent from HPA axis activation or from changes in emotional state; further studies would be necessary to ascertain the neural changes that could contribute to altered maternal behavior in stressed mothers. Moreover, these results suggest that the use of intragastric intubation during gestation would interfere with measures of drug induced changes in maternal behavior and likely their consequences on the offspring. PMID- 29179995 TI - Non-bilayer structures in mitochondrial membranes regulate ATP synthase activity. AB - Cardiolipin (CL) is an anionic phospholipid at the inner mitochondrial membrane (IMM) that facilitates the formation of transient non-bilayer (non-lamellar) structures to maintain mitochondrial integrity. CL modulates mitochondrial functions including ATP synthesis. However, the biophysical mechanisms by which CL generates non-lamellar structures and the extent to which these structures contribute to ATP synthesis remain unknown. We hypothesized that CL and ATP synthase facilitate the formation of non-bilayer structures at the IMM to stimulate ATP synthesis. By using 1H NMR and 31P NMR techniques, we observed that increasing the temperature (8 degrees C to 37 degrees C), lowering the pH (3.0), or incubating intact mitochondria with CTII - an IMM-targeted toxin that increases the formation of immobilized non-bilayer structures - elevated the formation of non-bilayer structures to stimulate ATP synthesis. The F0 sector of the ATP synthase complex can facilitate the formation of non-bilayer structures as incubating model membranes enriched with IMM-specific phospholipids with exogenous DCCD-binding protein of the F0 sector (DCCD-BPF) elevated the formation of immobilized non-bilayer structures to a similar manner as CTII. Native PAGE assays revealed that CL, but not other anionic phospholipids, specifically binds to DCCD-BPF to promote the formation of stable lipid-protein complexes. Mechanistically, molecular docking studies identified two lipid binding sites for CL in DCCD-BPF. We propose a new model of ATP synthase regulation in which CL mediates the formation of non-bilayer structures that serve to cluster protons and ATP synthase complexes as a mechanism to enhance proton translocation to the F0 sector, and thereby increase ATP synthesis. PMID- 29179997 TI - Elevated cyclic AMP levels promote BRAFCA/Pten-/- mouse melanoma growth but pCREB is negatively correlated with human melanoma progression. AB - Melanocyte development and differentiation are regulated by cAMP, which is produced by the adenylate cyclase (AC) enzyme upon activation of the melanocortin 1-receptor (MC1R). Individuals carrying single amino acid substitution variants of MC1R have impaired cAMP signaling and higher risk of melanoma. However, the contribution of AC to this risk is not clear. Downstream of AC, the phosphorylated transcription factor, cyclic AMP Responsive Element Binding Protein (pCREB), which is activated by protein kinase A, regulates the expression of several genes including the melanocyte master regulator MITF. The roles of AC and CREB in melanoma development and growth are not well understood. Here, we investigated the effect of topical application of AC inhibitor on BrafCA/Pten-/- mouse melanoma development. We show that AC inhibitor delays melanoma growth independent of MAPK pathway activity and melanin content. Next, employing a primary melanoma tissue microarray and quantitative immunohistochemistry, we show that pCREB levels are positively correlated with the proliferative status of melanoma, but low pCREB expression is associated with tumor aggressiveness and metastatic recurrence. These data suggest that low cAMP signaling inhibits tumor growth but is a predictor of melanoma aggressiveness. PMID- 29179999 TI - Phytochemicals as inhibitors of NF-kappaB for treatment of Alzheimer's disease. AB - Alzheimer's disease (AD) is the most prevalent form of dementia. The exact pathophysiology of this disease remains incompletely understood and safe and effective therapies are required. AD is highly correlated with neuroinflammation and oxidative stress in brain causing neuronal loss. Nuclear factor of activated B-cells (NF-kappaB) is involved in physiological inflammatory processes and thus representing a promising target for inflammation-based AD therapy. Phytochemicals are able to interfere with the NF-kappaB pathway. They inhibit the phosphorylation or the ubiquitination of signaling molecules, and thus, inhibit the degradation of IkappaB. The translocation of NF-kappaB to the nucleus and subsequent transcription of pro-inflammatory cytokines are inhibited by the actions of phytochemicals. Additionally, natural compounds preventing the interaction of NF-kappaB can block NF-kappaB's transcriptional activity by inhibiting its binding to target DNA. Many polyphenols including curcumin, resveratrol, pterostilbene, punicalagin, macranthoin G, salidroside, 4-O methylhonokiol, lycopene, genistein, obovatol and gallic acid were reported as potent NF-kappaB inhibitors for AD treatment. Several alkaloids such as galantamine, glaucocalyxin B, tetrandrine, berberine, oridonin, anatabine have been shown anti-inflammatory effects in AD models in vitro as well as in vivo. Besides, vitamins, tanshinone IIA, artemisinin, dihydroasparagusic acid, geniposide, xanthoceraside, l-theranine, 1,8-cineole and paeoniflorin were described as promising NF-kappaB inhibitors. In conclusion, natural products from plants represent interesting candidates for AD treatment. They may qualify as promising compounds for the development of derivatives providing enhanced pharmacological features. PMID- 29179998 TI - ELL2 regulates DNA non-homologous end joining (NHEJ) repair in prostate cancer cells. AB - ELL2 is an androgen-responsive gene that is expressed by prostate epithelial cells and is frequently down-regulated in prostate cancer. Deletion of Ell2 in the murine prostate induced murine prostatic intraepithelial neoplasia and ELL2 knockdown enhanced proliferation and migration in C4-2 prostate cancer cells. Here, knockdown of ELL2 sensitized prostate cancer cells to DNA damage and overexpression of ELL2 protected prostate cancer cells from DNA damage. Knockdown of ELL2 impaired non-homologous end joining repair but not homologous recombination repair. Transfected ELL2 co-immunoprecipitated with both Ku70 and Ku80 proteins. ELL2 could bind to and co-accumulate with Ku70/Ku80 proteins at sites of DNA damage. Knockdown of ELL2 dramatically inhibited Ku70 and Ku80 recruitment and retention at DNA double-strand break sites in prostate cancer cells. The impaired recruitment of Ku70 and Ku80 proteins to DNA damage sites upon ELL2 knockdown was rescued by re-expression of an ELL2 transgene insensitive to siELL2. This study suggests that ELL2 is required for efficient NHEJ repair via Ku70/Ku80 in prostate cancer cells. PMID- 29180000 TI - Usefulness of biochemical remission and transient elastography in monitoring disease course in autoimmune hepatitis. AB - BACKGROUND & AIMS: Liver fibrosis regression but also progression may occur in patients with autoimmune hepatitis (AIH) under treatment. There is a need for non invasive surrogate markers for fibrosis development in AIH to better guide immunosuppressive treatment. The aims of the study were to assess the impact of complete biochemical remission defined as normalisation of aminotransferases and IgG on histological activity and fibrosis development, and the value of repeat transient elastography (TE) measurement for monitoring disease progression in AIH. METHODS: A total of 131 liver biopsies from 60 patients with AIH and more than 900 TE from 125 patients with AIH, 130 with primary biliary cholangitis (PBC) and 100 with primary sclerosing cholangitis (PSC), were evaluated. Time intervals between TE were at least 12 months. Patients with AIH were treated for at least six months at first TE. RESULTS: In contrast to PBC and PSC, a decrease of liver stiffness (LS) was observed in the whole group of patients with AIH ( 6.2%/year; 95% CI -12.6% to -0.2%; p = 0.04). The largest decrease of LS was observed in patients with severe fibrosis at baseline (F4: -11.7%/year; 95% CI 19% to -3.5%; p = 0.006). Complete biochemical remission was strongly linked to regression of LS ("remission": -7.5%/year vs. "no remission": +1.7%/year, p <0.001). Similarly, complete biochemical remission predicted low histological disease activity and was the only independent predictor for histological fibrosis regression (relative risk3.66; 95% CI1.54-10.2; p = 0.001). Patients with F3/F4 fibrosis, who remained in biochemical remission showed a considerable decrease of fibrosis stage (3.7 +/- 0.5 to 1.8 +/- 1.7; p = 0.007) on histological follow-up. CONCLUSIONS: This study demonstrates that complete biochemical remission is a reliable predictor of a good prognosis in AIH and leads to fibrosis regression that can be monitored by TE. LAY SUMMARY: Autoimmune hepatitis is an inflammatory disease of the liver, which often progresses to cirrhosis if left untreated or in the case of insufficient treatment response. Current guidelines have defined biochemical remission (normalisation of biochemical markers for liver inflammation) as a major goal in the treatment of AIH. However, data on the prognostic relevance of this definition are scarce. Herein, we demonstrate that the current definition of biochemical remission is a reliable surrogate for low disease activity on histological assessment and for a beneficial long-term disease course. In addition, we establish transient elastography, a non-invasive ultrasound-based method of measuring scarring of liver tissue, as a reliable tool to monitor disease course in AIH. PMID- 29180001 TI - Effect of the FE2+ chelation by 2,2'-dipyridyl in the doxorubicin-induced lethality in breast tumor cell lines. AB - Breast cancer cells may exhibit changes in iron homeostasis, which results in increased labile iron pool (LIP) levels. Several studies highlight the crucial role of high LIP levels in the maintenance of tumor cell physiology. Iron chelators have been tested in anticancer therapy in combination with chemotherapeutic agents, to improve drug efficacy. Thus, the aim of this study was to evaluate the effect of 2,2'-dipyridyl (DIP), a Fe2+ chelator, in combination with doxorubicin (DOX) in breast tumor cells. The maximum concentration of DIP that did not significantly reduce the viability of MDA-MB 231 cells was 10MUM and for MCF-7 cells was 50MUM. We observed that MCF-7 had higher LIP levels than MDA-MB-231 cells. DIP alone increased ROS generation in MCF-7 cells, and DIP pretreatment reduced ROS generation induced by DOX treatment. In conclusion, the increase in MCF-7 cell viability induced by DIP pretreatment in DOX-treated cells seems to be related to an increase in the cellular antioxidant capacity and the iron chelator did not improve drug efficacy in the two breast tumor cell lines analyzed. PMID- 29180003 TI - Correlations of hair level with salivary level in cortisol and cortisone. AB - AIMS: Contrary findings exist on the consistency between hair cortisol and salivary cortisol in assessing the basal activity of the hypothalamic-pituitary adrenal (HPA) axis. The mismatches in temporal characteristic and the indices of hair and salivary cortisol might be potential reasons for the inconsistency. The aim of this study was to investigate the consistency between hair and salivary levels in cortisol and cortisone by directly examining the correlation between hair level and salivary level with different temporal characteristics (acute, short-term and long-term levels) and reflecting different HPA functions (basal level and reactivity level) in the well-matched time span. MAIN METHODS: A longitudinal design within a five-week period was conducted in a sample of 44 healthy female college students (mean age: 18.8yrs.; age range: 18-22yrs) of Han nationality with the exclusion criteria, such as use of oral contraceptives or glucocorticoids and bleached hairs, etc. Four saliva samples (awakening, awakening+30min, awakening+4h and awakening+9h) were collected from an identical participant on three separate days with an interval of one week and 1-cm hair segment nearest to the scalp was collected two weeks later after completing saliva collection. Cortisol and cortisone in saliva and hair were simultaneously measured with high performance liquid chromatography tandem mass spectrometry. KEY FINDINGS: There were significantly moderate correlations in cortisol and cortisone between hair level and three-day average of single-day salivary level, but low to moderate correlations between hair level and single-point and single day salivary level. Hair cortisol and cortisone were unrelated to single-day level and three-day average of diurnal slope and cortisol awakening response of salivary cortisol and cortisone, respectively. SIGNIFICANCE: The considerable consistency between hair level and long-term salivary level in cortisol and cortisone implies that cortisol and cortisone in hair are valid biomarkers of cumulative exposure of cortisol and cortisone to retrospectively reflect long term basal activity of the HPA system. PMID- 29180002 TI - Melatonin mitigates thioacetamide-induced hepatic fibrosis via antioxidant activity and modulation of proinflammatory cytokines and fibrogenic genes. AB - AIMS: The potential antifibrotic effects of melatonin against induced hepatic fibrosis were explored. MAIN METHODS: Rats were allocated into four groups: placebo; thioacetamide (TAA) (200mg/kg bwt, i.p twice weekly for two months); melatonin (5mg/kgbwt, i.p daily for a week before TAA and continued for an additional two months); and melatonin plus TAA. Hepatic fibrotic changes were evaluated biochemically and histopathologically. Hepatic oxidative/antioxidative indices were assessed. The expression of hepatic proinflammatory cytokines (tumor necrosis factor-alpha, and interleukin-1beta), fibrogenic-related genes (transforming growth factor-1beta, collagen I, collagen, III, laminin, and autotaxin) and an antioxidant-related gene (thioredoxin-1) were detected by qRT PCR. KEY FINDINGS: In fibrotic rats, melatonin lowered serum aspartate aminotransferase, alanine aminotransferase, and autotaxin activities, bilirubin, hepatic hydroxyproline and plasma ammonia levels. Melatonin displayed hepatoprotective and antifibrotic potential as indicated by mild hydropic degeneration of some hepatocytes and mild fibroplasia. In addition, TAA induced the depletion of glutathione, glutathione s-transferase, glutathione peroxidase, superoxide dismutase, catalase, and paraoxonase-1 (PON-1), while inducing the accumulation of malondialdehyde, protein carbonyl (C=O) and nitric oxide (NO), and DNA fragmentation. These effects were restored by melatonin pretreatment. Furthermore, melatonin markedly attenuated the expression of proinflammatory cytokines and fibrogenic genes via the upregulation of thioredoxin-1 mRNA transcripts. SIGNIFICANCE: Melatonin exhibits potent anti-inflammatory, antioxidant and fibrosuppressive activities against TAA-induced hepatic fibrogenesis via the suppression of oxidative stress, DNA damage, proinflammatory cytokines and fibrogenic gene transcripts. In addition, we demonstrate that the antifibrotic activity of melatonin is mediated by the induction of thioredoxin-1 with attenuation of autotaxin expressions. PMID- 29180004 TI - Estimating a person's age from walking over a sensor floor. AB - Ageing has an effect on many parameters of the physical condition, and one of them is the way a person walks. This property, the gait pattern, can unintrusively be observed by letting people walk over a sensor floor. The electric capacitance sensors built into the floor deliver information about when and where feet get into close proximity and contact with the floor during the phases of human locomotion. We processed gait patterns recorded this way by extracting a feature vector containing the discretised distribution of occurring geometrical extents of significant sensor readings. This kind of feature vector is an implicit measure encoding the ratio of swing-to stance phase timings in the gait cycle and representing how cleanly the leg swing is performed. We then used the dataset to train a Multi-Layer Perceptron to perform regression with the age of the person as the target value, and the feature vector as input. With this method and a dataset size of 142 persons recorded, we achieved a mean absolute error of approximately 10 years between the true age and the estimated age of the person. Considering the novelty of our approach, this is an acceptable result. The combination of a floor sensor and machine learning methods for interpreting the sensor data seems promising for further research and applications in care and medicine.

To investigate the causal role of these regions during the detection of pitch deviants, we applied cathodal (inhibitory) transcranial direct current stimulation (tDCS) over right frontal and right temporal regions during separate testing sessions. We recorded participants' electrical brain activity (EEG) before and after tDCS stimulation while they performed a pitch change detection task. Relative to a sham condition, there was a decrease in P3 amplitude after cathodal stimulation over both frontal and temporal regions compared to pre-stimulation baseline. This decrease was associated with small pitch deviations (6.25 cents), but not large pitch deviations (200 cents). Overall, this demonstrates that using tDCS to disrupt regions around the IFG and AC can induce temporary changes in evoked brain activity when processing pitch deviants. These electrophysiological changes are similar to those observed in amusia and provide causal support for the connection between P3 and fronto temporal brain regions. PMID- 29180005 TI - Leisure-time physical activity across adulthood and biomarkers of cardiovascular disease at age 60-64: A prospective cohort study. AB - BACKGROUND AND AIMS: This study examined associations between leisure-time physical activity (LTPA) across adulthood (from age 36) and cardiovascular disease (CVD) biomarkers at age 60-64. METHODS: LTPA was reported by study participants from the MRC National Survey of Health and Development at ages 36, 43, 53 and 60-64 (n = 1754) and categorised as inactive, moderately active (1 4/month) or most active (5+/month) at each age. Linear regression was used to examine associations between a cumulative adulthood LTPA score (range = 0-8), and change in LTPA between ages 36 and 60-64 (i.e. always inactive, became inactive, became active, always active) and inflammatory [C-reactive protein (CRP), interleukin-6 (IL-6)], endothelial [tissue-Plasminogen Activator (t-PA), E selectin] and adipokine [leptin, adiponectin] measures extracted from overnight fasting blood samples at age 60-64. RESULTS: The more active a participant was over adulthood, the better their biomarker profile, e.g. fully-adjusted difference in t-PA (both sexes) and adiponectin (women) per unit increase in the LTPA score (95% confidence interval) = -2.2% (-3.6; -0.8) and 2.0% (0.2; 3.8). Those that became active at age 60-64 showed slightly healthier biomarker profiles than those that became inactive [e.g. fully-adjusted difference in IL-6 = -9.9% (-23.9; 4.1) vs. -3.8% (-12.4; 4.8)], although the best profiles were seen for those always active [IL-6: -15.0% (-24.2; -5.7)], when compared with the always inactive group. CONCLUSIONS: Greater accumulation of LTPA across adulthood was associated with a more favourable CVD biomarker profile in early old age. Earlier uptake and long-term maintenance of LTPA may provide the greatest benefits for CVD prevention.

AB - The high concentrations of nitric oxide (NO) produced by inducible nitric oxide synthase (iNOS) in activated glial cells in response to neuroinflammatory stimuli have neurotoxic effects on the brain. At basal levels, iNOS expression is low, and proinflammatory stimuli induce iNOS expression in astrocytes, microglia, and oligodendrocytes. Fyn, a non-receptor tyrosine kinase, regulates iNOS expression in several types of immune cells. However, its role in stimulated astrocytes is less clear. In this study, we investigated the role of Fyn in the regulation of lipopolysaccharide (LPS)-induced iNOS expression in astrocytes from mice and rats. Intracerebroventricular LPS injections in cortical regions enhanced iNOS mRNA and protein levels, which were increased in Fyn-deficient mice. Accordingly, LPS-induced nitrite production was enhanced in primary astrocytes cultured from Fyn-deficient mice or rats. Similar results were observed in cultured astrocytes after the siRNA-induced knockdown of Fyn expression. Finally, we observed increased LPS-induced extracellular signal-regulated protein kinase (ERK) activation in Fyn-deficient astrocytes. These results suggested that Fyn has a regulatory role in iNOS expression in astrocytes during neuroinflammatory responses. PMID- 29180008 TI - Identification and characterization of human bone-derived cells. AB - This study was designed to identify and characterize primary bone-derived cells (BdCs) and investigate the potential role of osteoblast differentiation. Primary BdCs were isolated from surgical bone for comparative analysis with mesenchymal stem cells (MSCs) and fetal osteoblasts (FOBs) and for potential differentiation to mature osteoblasts. Using three different cells, we successfully cultivated human osteoblast differentiation and activity which were evaluated using microarray and biochemical methods. BdCs are more correlated to MSCs in bioinformatics result and similar with FOBs in gene expression. In particular, Osterix, osteoprogenitor marker, was high expressed in BdCs, while the expression in MSCs and FOBs were very low. Furthermore, BdCs exhibited a marked alkaline phosphatase (ALP) expression, early stage of osteogenic marker, and retained osteogenic properties and physiological changes into maturation as in FOBs. BdCs also showed an increase in bone morphogenic protein 2 (BMP2), osteopontin (OPN), and osteocalcin (OCN) mRNA expressions during differentiation. This study suggests that BdCs may be osteoprogenitor cells or undifferentiated preosteoblasts with strong capacity to differentiate toward mature osteoblasts. PMID- 29180009 TI - Regulation of the Plasma Membrane Calcium ATPases by the actin cytoskeleton. AB - Associations between the cortical cytoskeleton and the components of the plasma membrane are no longer considered to be merely of structural and mechanical nature but are nowadays recognized as dynamic interactions that modulate a plethora of cellular responses. Reorganization of actin filaments upon diverse stimuli - among which is the rise in cytosolic Ca2+ - is involved in cell motility and adhesion, phagocytosis, cytokinesis, and secretion. Actin dynamics also participates in the regulation of ion transport across the membranes where it not only plays a key role in the delivery and stabilization of channels and transporters in the plasma membrane but also in the regulation of their activity. The recently described functional interaction between actin and the Plasma Membrane Ca2+-ATPase (PMCA) represents a novel regulatory mechanism of the pump at the time that unveils a new pathway by which the cortical actin cytoskeleton participates in the regulation of cytosolic Ca2+ homeostasis. In this review, we summarize the current knowledge on the interaction between the cortical actin cytoskeleton and the PMCA and discuss the possible mechanisms that may explain the pump's modulation. PMID- 29180010 TI - Role of N-myristoylation in stability and subcellular localization of the CLPABP protein. AB - Cardiolipin and phosphatidic acid-binding protein (CLPABP) controls the stability of the mRNA harboring an AU-rich element (ARE) in the 3' UTR with the help of the RNA stabilizer, human antigen R (HuR). Although CLPABP is localized on the mitochondrial surface as a large protein-RNA complex, its precise role is not yet known. Recently, CLPABP was identified as an N-myristoylated protein. Here, we demonstrate the effects of N-myristoylation on the functions of CLPABP. In the present study, compared to the wild-type protein that possessed the "MG" motif at the N-terminus for N-myristoylation, the mutant CLPABP protein that lacked N myristoylation modification site was unstable. Furthermore, the expression of the G/A mutant of CLPABP, which lacked N-myristoylation site, induced morphological alterations in mitochondria. Because pleckstrin homology domain-deleted mutant, which was fused with the N-myristoylation site derived from intact CLPABP, could not colocalize with mitochondria, N-myristoylation of CLPABP was predicted to affect its stability onto the mitochondrial membrane rather than its subcellular localization. PMID- 29180011 TI - Unbiased compound screening with a reporter gene assay highlights the role of p13 in the cardiac cellular stress response. AB - We recently showed that a 13-kDa protein (p13), the homolog protein of formation of mitochondrial complex V assembly factor 1 in yeast, acts as a potential protective factor in pancreatic islets under diabetes. Here, we aimed to identify known compounds regulating p13 mRNA expression to obtain therapeutic insight into the cellular stress response. A luciferase reporter system was developed using the putative promoter region of the human p13 gene. Overexpression of peroxisome proliferator-activated receptor gamma coactivator 1alpha, a master player regulating mitochondrial metabolism, increased both reporter activity and p13 expression. Following unbiased screening with 2320 known compounds in HeLa cells, 12 pharmacological agents (including 8 cardiotonics and 2 anthracyclines) that elicited >2-fold changes in p13 mRNA expression were identified. Among them, four cardiac glycosides decreased p13 expression and concomitantly elevated cellular oxidative stress. Additional database analyses showed highest p13 expression in heart, with typically decreased expression in cardiac disease. Accordingly, our results illustrate the usefulness of unbiased compound screening as a method for identifying novel functional roles of unfamiliar genes. Our findings also highlight the importance of p13 in the cellular stress response in heart. PMID- 29180012 TI - Weighted gene co-expression network analysis reveals potential genes involved in early metamorphosis process in sea cucumber Apostichopus japonicus. AB - Sea cucumbers, one main class of Echinoderms, have a very fast and drastic metamorphosis process during their development. However, the molecular basis under this process remains largely unknown. Here we systematically examined the gene expression profiles of Japanese common sea cucumber (Apostichopus japonicus) for the first time by RNA sequencing across 16 developmental time points from fertilized egg to juvenile stage. Based on the weighted gene co-expression network analysis (WGCNA), we identified 21 modules. Among them, MEdarkmagenta was highly expressed and correlated with the early metamorphosis process from late auricularia to doliolaria larva. Furthermore, gene enrichment and differentially expressed gene analysis identified several genes in the module that may play key roles in the metamorphosis process. Our results not only provide a molecular basis for experimentally studying the development and morphological complexity of sea cucumber, but also lay a foundation for improving its emergence rate. PMID- 29180013 TI - Development of a novel cellulase biosensor that detects crystalline cellulose hydrolysis using a transcriptional regulator. AB - Successful utilization of cellulose as renewable biomass depends on the development of economically feasible technologies, which can aid in enzymatic hydrolysis. In this study, we developed a whole-cell biosensor for detecting cellulolytic activity that relies on the recognition of cellobiose using the transcriptional factor CelR from Thermobifida fusca and transcriptional activation of its downstream gfp reporter gene. The fluorescence intensity of whole-cell biosensor, which was named as cellobiose-detectible genetic enzyme screening system (CBGESS), was directly proportional to the concentration of cellobiose. The strong fluorescence intensity of CBGESS demonstrated the ability to detect cellulolytic activity with two cellulosic substrates, carboxymethyl cellulose and p-nitrophenyl beta-D-cellobioside in cellulase-expressing Escherichia coli. In addition, CBGESS easily sensed crystalline cellulolytic activity when commercial Celluclast 1.5L was dropped on an Avicel plate. Therefore, CBGESS is a powerful tool for detecting cellulolytic activity with high sensitivity in the presence of soluble or insoluble cellulosic substrates. CBGESS may be further applied to excavate novel cellulases or microbes from both genetic libraries and various environments. PMID- 29180014 TI - Structural insights into the oligomerization of FtsH periplasmic domain from Thermotoga maritima. AB - Prompt removal of misfolded membrane proteins and misassembled membrane protein complexes is essential for membrane homeostasis. However, the elimination of these toxic proteins from the hydrophobic membrane environment has high energetic barriers. The transmembrane protein, FtsH, is the only known ATP-dependent protease responsible for this task. The mechanisms by which FtsH recognizes, unfolds, translocates, and proteolyzes its substrates remain unclear. The structure and function of the ATPase and protease domains of FtsH have been previously characterized while the role of the FtsH periplasmic domain has not clearly identified. Here, we report the 1.5-1.95 A resolution crystal structures of the Thermotoga maritima FtsH periplasmic domain (tmPD) and describe the dynamic features of tmPD oligomerization. PMID- 29180015 TI - Pyruvic acid prevents Cu2+/Zn2+-induced neurotoxicity by suppressing mitochondrial injury. AB - Zinc (Zn) is known as a co-factor for over 300 metalloproteins or enzymes, and has essential roles in many physiological functions. However, excessively high Zn concentrations are induced in pathological conditions such as interruption of blood flow in stroke or transient global ischemia-induced neuronal cell death. Furthermore, we recently found that copper (Cu2+) significantly exacerbates Zn2+ neurotoxicity in mouse hypothalamic neuronal cells, suggesting that Zn2+ interaction with Cu2+ is important for the development of neurological disease. Meanwhile, organic acids such as pyruvic acid and citric acid are reported to prevent neuronal cell death induced by various stresses. Thus, in this study, we focused on organic acids and searched for compounds that inhibit Cu2+/Zn2+ induced neurotoxicity. Initially, we examined the protective effect of various organic acids on Cu2+/Zn2+-induced neurotoxicity, and found that pyruvic acid clearly suppresses Cu2+/Zn2+-induced neurotoxicity in GT1-7 cells. Next, we examined the protective mechanisms of pyruvic acid against Cu2+/Zn2+-induced neurotoxicity. Specifically, we examined the possibilities that pyruvic acid chelates Cu2+ and Zn2+ or suppresses the ER stress response, but found that neither was suppressed by pyruvic acid treatment. In contrast, pyruvic acid significantly suppressed cytochrome c release into cytoplasm, an index of mitochondrial injury, in a dose-dependent manner. These results suggest that pyruvic acid prevents Cu2+/Zn2+-induced neuronal cell death by suppressing mitochondrial injury. Based on our results, we assume that pyruvic acid may be therapeutically beneficial for neurological diseases involving neuronal cell death such as vascular dementia. PMID- 29180016 TI - Cytochrome P450 CYP716A254 catalyzes the formation of oleanolic acid from beta amyrin during oleanane-type triterpenoid saponins biosynthesis in Anemone flaccida. AB - Anemone flaccida Fr. Shmidt (Ranunculaceae), known as 'Di Wu' in China, is a perennial herb which has long been used to treat arthritis. The rhizome of A. flaccida contains pharmacologically active components i.e. oleanane-type triterpenoid saponins. Oleanolic acid is natural triterpenoid in plants with diverse biological activities. The biosynthesis of oleanolic acid involves cyclization of 2,3-oxidosqualene to the oleanane-type triterpenoid skeleton, followed by a series of oxidation reactions catalyzed by cytochrome P450 monooxygenase (CYP450). Previously, we identified four possible cytochrome P450 genes belonging to CYP716A subfamily from the transcriptome of A. flaccida. In this study, we identified one of those genes "CYP716A254" encoding a cytochrome P450 monooxygenase from A. flaccida that catalyzes the conversion of the beta amyrin into oleanolic acid. The heterologous expression of CYP716A254 in yeast resulted in oxidation of beta-amyrin at the C-18 position to oleanolic acid production. These results provide an important basis for further studies of oleanane-type triterpenoid saponins synthesis in A. flaccida. PMID- 29180017 TI - Role of osteopontin and its regulation in pancreatic islet. AB - Osteopontin (OPN) is involved in various physiological processes and also implicated in multiple pathological states. It has been suggested that OPN may have a role in type 2 diabetes (T2D) by protecting pancreatic islets and interaction with incretins. However, the regulation and function of OPN in islets, especially in humans, remains largely unexplored. In this study, we performed our investigations on both diabetic mouse model SUR1-E1506K+/+ and islets from human donors. We demonstrated that OPN protein, secretion and gene expression was elevated in the diabetic SUR1-E1506K+/+ islets. We also showed that high glucose and incretins simultaneously stimulated islet OPN secretion. In islets from human cadaver donors, OPN gene expression was elevated in diabetic islets, and externally added OPN significantly increased glucose-stimulated insulin secretion (GSIS) from diabetic but not normal glycemic donors. The increase in GSIS by OPN in diabetic human islets was Ca2+ dependent, which was abolished by Ca2+-channel inhibitor isradipine. Furthermore, we also confirmed that OPN promoted cell metabolic activity when challenged by high glucose. These observations provided evidence on the protective role of OPN in pancreatic islets under diabetic condition, and may point to novel therapeutic targets for islet protection in T2D. PMID- 29180018 TI - Isoliquiritigenin protects against sepsis-induced lung and liver injury by reducing inflammatory responses. AB - Sepsis, one of the most fatal diseases worldwide, often leads to multiple organ failure, mainly due to uncontrolled inflammatory responses. Despite accumulating knowledge obtained in recent years, effective drugs to treat sepsis in the clinic are still urgently needed. Isoliquiritigenin (ISL), a chalcone compound, has been reported to exert anti-inflammatory properties. However, little is known about the effects of ISL on sepsis and its related complications. In this study, we investigated the potential protective effects of ISL on lipopolysaccharide (LPS) induced injuries and identified the mechanisms underlying these effects. ISL inhibited inflammatory cytokine expression in mouse primary peritoneal macrophages (MPMs) exposed to LPS. In an acute lung injury (ALI) mouse model, ISL prevented LPS-induced structural damage and inflammatory cell infiltration. Additionally, pretreatment with ISL attenuated sepsis-induced lung and liver injury, accompanied by a reduction in inflammatory responses. Moreover, these protective effects were mediated by the nuclear factor kappa B (NF-kappaB) pathway-mediated inhibition of inflammatory responses in vitro and in vivo. Our study suggests that ISL may be a potential therapeutic agent for sepsis-induced injuries. PMID- 29180019 TI - Overcoming challenges for amplified expression of recombinant proteins using Escherichia coli. AB - A thorough characterisation of the genetics, physiology and metabolism of Escherichia coli has led to the availability of a large number of strains and vectors suitable for recombinant protein expression. Despite the relative ease in using E. coli for achieving amplified expression of many recombinant proteins, for some proteins this can be a frustrating and time-consuming process leading to very low expression or no expression at all. This is especially true for membrane proteins, which introduce additional challenges. A number of factors can be considered and optimised for achieving required levels of amplified expression of recombinant proteins in E. coli that are broadly classified as host strain, expression vector and growth conditions. In this paper we summarise these factors and consolidate the common challenges encountered and approaches to overcome them, focusing in particular on cases where there is low amplified expression or no expression at all of the desired recombinant protein, due to various reasons. PMID- 29180020 TI - Aptamers in Bordeaux 2017: An exceptional "millesime". AB - About 150 participants attended the symposium organised at the Palais de la Bourse in Bordeaux, France on September 22-23, 2017. Thirty speakers from all over the world delivered lectures covering selection processes, aptamer chemistry and innovative applications of these powerful tools that display major advantages over antibodies. Beyond the remarkable science presented, lively discussion and fruitful exchange between participants made this meeting a great success. A series of lectures were focused on synthetic biology (riboswitches, new synthetic base pairs, mutated polymerases). Innovative selection procedures including functional screening of oligonucleotide pools were described. Examples of aptasensors for the detection of pathogens were reported. The potential of aptamers for the diagnostic and the treatment of diseases was also presented. Brief summaries of the lectures presented during the symposium are given in this report. The third edition of this symposium will take place in Boulder, Colorado in Summer 2018 (information available at http://www.aptamers-in-bordeaux.com/). PMID- 29180021 TI - Insulin resistance in 3T3-L1 adipocytes by TNF-alpha is improved by punicic acid through upregulation of insulin signalling pathway and endocrine function, and downregulation of proinflammatory cytokines. AB - Insulin resistance (IR) has become a major threat to public health due to its role in metabolic syndrome. Inflammation associated with IR is an interesting area of biomedical research in recent years and is expected to affect insulin signalling pathway via downregulating glucose transporters. In the present study, we evaluate the potential of punicic acid (PA), a nutraceutical found in pomegranate seed oil, against TNF-alpha induced alteration in 3T3-L1 adipocytes on glucose metabolism, endocrine function and inflammation. IR was induced in 3T3 L1 adipocytes by treating with TNF-alpha (10 ng/mL) and various concentrations of PA (5, 10, 30 MUM) were incubated simultaneously. After 24 h, we found that TNF alpha treatment increased mRNA expression of SOCS3, PTP1B and a decrease in IRS1 causing diminished glucose uptake. Further, it showed significantly increased transcriptional activity of NFkappaB and leptin secretion while PA maintained leptin levels normal. Additionally, PA prevented the over-expression of phosphorylated JNK in a dose dependent manner during IR. PA also ameliorated significantly the upregulation of proinflammatory cytokines. From the results, we conclude that PA is effective to ameliorate TNF-alpha induced IR and also we recommend the intake of PA for control and management of IR and its associated complications. PMID- 29180022 TI - Toxicological assessment of lower alkyl methacrylate esters by a category approach. AB - Categories and read-across are essential tools for supplying information for assessments of endpoints without data while minimizing animal testing. This study is based on the guidance of ECHA in its Read-Across Framework (RAAF). A category of C1 - C8 alkyl methacrylate esters (methyl, ethyl, n-butyl, iso-butyl and 2 ethylhexyl) was constructed to fill in missing information for human health endpoints using read-across as a permitted adaptation under EU REACH. The esters form a series with common functional groups, small incremental changes of electrophilicity by molecular weight, and rapid hydrolysis by ester cleavage. Read-across is justified by two common specific modes of action, direct electrophilic reaction of the parent compounds and the potential inherent toxicities of the common metabolites methacrylic acid and the corresponding alcohols. The toxicological profile is very similar for all category members and not driven by the alcohol metabolites. Data gaps can be filled in with high confidence based on the number of studies available, the effects therein observed and the toxicological profiles of the hydrolysis products. The guidance provided by the RAAF enabled data gaps to be filled in a robust manner. PMID- 29180023 TI - Effect of Patiromer on Hyperkalemia Recurrence in Older Chronic Kidney Disease Patients Taking RAAS Inhibitors. AB - BACKGROUND: Older people are predisposed to hyperkalemia because of impaired renal function, comorbid conditions, and polypharmacy. Renin-angiotensin aldosterone system inhibitors (RAASi), which are recommended to treat chronic kidney disease and heart failure augment the risk. Patiromer, a nonabsorbed potassium binder, was shown in the phase 3 OPAL-HK study to decrease serum potassium in patients with chronic kidney disease taking RAASi. We studied the efficacy and safety of patiromer in a prespecified subgroup of patients aged >=65 years from OPAL-HK. METHODS: Chronic kidney disease patients with mild or moderate-to-severe hyperkalemia received patiromer, initially 8.4 g/d or 16.8 g/d, respectively, for 4 weeks (treatment phase, part A). Eligible patients entered an 8-week randomized withdrawal phase (part B) and continued patiromer or switched to placebo. RESULTS: Mean +/- standard error change in serum potassium from baseline to week 4 of part A (primary endpoint) in patients aged >=65 years was -1.01 +/- 0.05 mEq/L (P < .001); 97% achieved serum potassium 3.8-<5.1 mEq/L. The serum potassium increase during the first 4 weeks of part B was greater in patients taking placebo than in those taking patiromer (P < .001). Fewer patients taking patiromer (30%) than placebo (92%) developed recurrent hyperkalemia (serum potassium >=5.1 mEq/L). Mild-to-moderate constipation occurred in 15% (part A) and 7% (part B) of patients aged >=65 years. Serum potassium <3.5 mEq/L and serum magnesium <1.4 mg/dL were infrequent (4% each in patients aged >=65 years in part A). CONCLUSIONS: Patiromer reduced recurrent hyperkalemia and was well tolerated in older chronic kidney disease patients taking RAASi. PMID- 29180024 TI - Impact of Home Health Care on Health Care Resource Utilization Following Hospital Discharge: A Cohort Study. AB - BACKGROUND: As healthcare costs rise, home health care represents an opportunity to reduce preventable adverse events and costs following hospital discharge. No studies have investigated the utility of home health care within the context of a large and diverse patient population. METHODS: A retrospective cohort study was conducted between 1/1/2013 and 6/30/2015 at a single tertiary care institution to assess healthcare utilization after discharge with home health care. Control patients discharged with "self-care" were matched by propensity score to home health care patients. The primary outcome was total healthcare costs in the 365 day post-discharge period. Secondary outcomes included follow-up readmission and death. Multivariable linear and Cox proportional hazards regression were used to adjust for covariates. RESULTS: Among 64,541 total patients, 11,266 controls were matched to 6,363 home health care patients across 11 disease-based Institutes. During the 365-day post-discharge period, home health care was associated with a mean unadjusted savings of $15,233 per patient, or $6,433 after adjusting for covariates (p < 0.0001). Home health care independently decreased the hazard of follow-up readmission (HR 0.82, p < 0.0001) and death (HR 0.80, p < 0.0001). Subgroup analyses revealed that home health care most benefited patients discharged from the Digestive Disease (death HR 0.72, p < 0.01), Heart & Vascular (adjusted savings of $11,453, p < 0.0001), Medicine (readmission HR 0.71, p < 0.0001), and Neurological (readmission HR 0.67, p < 0.0001) Institutes. CONCLUSIONS: Discharge with home health care was associated with significant reduction in healthcare utilization and decreased hazard of readmission and death. These data inform development of value-based care plans. PMID- 29180025 TI - Delay from Diagnosis to Surgery in Transferred Type A Aortic Dissection. AB - OBJECTIVES: The purpose of this research is to analyze factors associated with delays to surgical management of Type A acute aortic dissection patients. METHODS: Time from diagnosis to surgery and associated factors were evaluated in 1880 surgically managed Type A dissection patients enrolled in the International Registry of Acute Aortic Dissection. RESULTS: The majority of patients were transferred (75.7% vs 24.3%). Patients who were transferred had a median delay from diagnosis to surgery of 4.0 hours (interquartile range 2.5-7.2 hours), compared with 2.3 hours (interquartile range 1.1-4.2 hours; P < .001) in nontransferred patients. Among patients who were transferred, those with worst ever, posterior, or tearing chest pain those with severe complications, and those receiving transthoracic echocardiogram prior to a transesophageal echocardiogram or as the only echocardiogram were treated more quickly. Those undergoing magnetic resonance imaging, or who had prior cardiac surgery, had longer delays to surgery. Among nontransferred patients, those with coma were treated more quickly. In both groups, patients presenting with emergent conditions such as cardiac tamponade, hypotension, or shock had more rapid treatment. Among transferred patients, surviving patients had longer delays (4.1 [2.6-7.8] hours vs 3.3 [2.0-6.0] hours, P = .001). Overall mortality did not differ between patients who were transferred vs not (19.3% vs 21.1%, P = .416). CONCLUSION: Simply being transferred added significantly to the delay to surgery for Type A acute aortic dissection patients, but a number of factors affected its extent. Overall, signs and symptoms leading to a definitive diagnosis or indicating immediate life threat reduced time to surgery, while factors suggesting other diagnoses correlated with delays. PMID- 29180026 TI - Intramolecular and Intermolecular FRET Sensors for GPCRs - Monitoring Conformational Changes and Beyond. AB - Within the past decade, a large increase in structural knowledge from crystallographic studies has significantly fostered our understanding of the structural biology of G protein-coupled receptors (GPCRs). However, information on dynamic events upon receptor activation or deactivation is not yet readily accessed by these structural approaches. GPCR-based fluorescence resonance energy transfer or bioluminescence resonance energy transfer sensors or sensors for interacting proteins (e.g., G proteins or arrestins) can in part cover this gap. The principal design of such sensors was reported 15 years ago. Since then, sensors for almost 20 different GPCRs have been designed. If used with necessary controls and cautious interpretation, such sensors can contribute significantly to our understanding of the basic mechanisms of GPCR function and beyond. In this review, we will discuss the recent developments in this area of GPCR dynamics. PMID- 29180027 TI - Nasopharyngeal s. pneumoniae carriage and density in Belgian infants after 9 years of pneumococcal conjugate vaccine programme. AB - BACKGROUND: In Belgium, the infant pneumococcal conjugate vaccine (PCV) programme changed from PCV7 (2007-2011) to PCV13 (2011-2015) and to PCV10 (2015-2016). A 3 year nasopharyngeal carriage study was initiated during the programme switch in 2016. Main objective of the year 1 assessment was to obtain a baseline measurement of pneumococcal carriage prevalence, carriage density, serotype distribution and antibiotic resistance. MATERIALS/METHODS: Two infant populations aged 6-30 months and without use of antibiotics in the seven days prior to sampling were approached: (1) attending one of 85 randomly selected day-care centres (DCC); (2) presenting with AOM at study-trained general practitioners and paediatricians. Demographic and clinical characteristics were documented and a single nasopharyngeal swab was taken. S. pneumoniae were cultured, screened for antibiotic resistance and serotyped, and quantitative Taqman real-time PCR (qRT PCR) targeting LytA was performed. RESULTS: Culture-based (DCC: 462/760; 60.8% - AOM: 27/39; 69.2%) and LytA-based (DCC: 603/753; 80.1% - AOM: 32/39; 82.1%) carriage prevalence was high. Average pneumococcal DNA load in LytA-positive day care samples was 6.5 * 106 copies/ul (95%CI = 3.9-9.2 * 106, median = 3.5 * 105); DNA load was positively associated with signs of common cold and negatively with previous antibiotic use. Culture-based frequency of 13 pneumococcal vaccine (PCV) serotypes was 5.4% in DCC and 7.7% in AOM, with 19F and 14 being most frequent, and frequencies below 0.5% for serotypes 3, 6A, 19A in both populations. Predominant non-PCV serotypes were 23B and 23A in day-care and 11A in infants with AOM. In day-care, resistance to penicillin was rare (<0.5%) and absent against levofloxacin; 32.7% and 16.9% isolates were cotrimoxazole- and erythromycin-resistant respectively. CONCLUSION: Four years after PCV13 introduction in the vaccination programme, PCV13 serotype carriage was rare in infants throughout Belgium and penicillin resistance was rare. Continued surveillance in the context of a PCV programme switch is necessary. PMID- 29180029 TI - Vaccine hesitancy terminology: A response to Bedford et al. PMID- 29180028 TI - Dual-route targeted vaccine protects efficiently against botulinum neurotoxin A complex. AB - Clostridium botulinum readily persists in the soil and secretes life-threatening botulinum neurotoxins (BoNTs) that are categorized into serotypes A to H, of which, serotype A (BoNT/A) is the most commonly occurring in nature. An efficacious vaccine with high longevity against BoNT intoxication is urgent. Herein, we developed a dual-route vaccine administered over four consecutive weeks by mucosal and parenteral routes, consisting of the heavy chain (Hc) of BoNT/A targeting dendritic cell peptide (DCpep) expressed by Lactobacillus acidophilus as a secretory immunogenic protein. The administered dual-route vaccine elicited robust and long-lasting memory B cell responses comprising germinal center (GC) B cells and follicular T cells (Tfh) that fully protected mice from lethal oral BoNT/A fatal intoxication. Additionally, passively transferring neutralizing antibodies against BoNT/A into naive mice induced robust protection against BoNT/A lethal intoxication. Together, a targeted vaccine employing local and systemic administrative routes may represent a novel formulation eliciting protective B cell responses with remarkable longevity against threatening biologic agents such as BoNTs. PMID- 29180030 TI - The efficacy of recombinant turkey herpesvirus vaccines targeting the H5 of highly pathogenic avian influenza virus from the 2014-2015 North American outbreak. AB - The outbreak of highly pathogenic avian influenza virus in North American poultry during 2014 and 2015 demonstrated the devastating effects of the disease and highlighted the need for effective emergency vaccine prevention and control strategies targeted at currently circulating strains. This study evaluated the efficacy of experimental recombinant turkey herpesvirus vector vaccines with three different inserts targeting the hemagglutinin gene of an isolate from the recent North American influenza outbreak. White leghorn chickens were vaccinated at one day of age and challenged with A/Turkey/Minnesota/12582/2015 H5N2 at 4 weeks of age. Birds were analyzed for survival, viral shedding at two and four days after infection, and specific antibody prior to challenge and from surviving birds. The three experimental vaccines demonstrated 100%, 45% and 15% survival with the most effective vaccine significantly reducing oral and cloacal viral shedding compared to all other groups and generated specific antibody prior to challenge with highly pathogenic avian influenza virus. More studies are needed using diverse H5Nx highly pathogenic virus isolates to fully determine the breadth of coverage against possible exposure strains, as well as possible impact of maternally derived antibody on protection and vaccine efficacy. PMID- 29180031 TI - Will we have new pertussis vaccines? AB - Despite wide vaccination coverage with efficacious vaccines, pertussis is still not under control in any country. Two types of vaccines are available for the primary vaccination series, diphtheria/tetanus/whole-cell pertussis and diphtheria/tetanus/acellular pertussis vaccines, in addition to reduced antigen content vaccines recommended for booster vaccination. Using these vaccines, several strategies are being explored to counter the current pertussis problems, including repeated vaccination, cocoon vaccination and maternal immunization. With the exception of the latter, none have proven their effectiveness, and even maternal vaccination is not expected to ultimately control pertussis. Therefore, new pertussis vaccines are needed, and several candidates are in early pre clinical development. They include whole-cell vaccines with low endotoxin content, outer membrane vesicles, new formulations, acellular vaccines with new adjuvants or additional antigens and live attenuated vaccines. The most advanced is the live attenuated nasal vaccine BPZE1. It provides strong protection in mice and non-human primates, is safe, even in immune compromised animals, and genetically stable after in vitro and in vivo passages. It also has interesting immunoregulatory properties without being immunosuppressive. It has successfully completed a first-in-man clinical trial, where it was found to be safe, able to transiently colonize the human respiratory tract and to induce immune responses in the colonized subjects. It is now undergoing further clinical development. As it is designed to reduce carriage and transmission of Bordetella pertussis, it may hopefully contribute to the ultimate control of pertussis.

AB - Interferon regulatory factors (IRFs) are a family of mediators in various biological processes including immune modulation of interferon (IFN) and proinflammatory cytokine expression. However, the data on the complete composition of IRFs is rather limited in teleost fish. In the present study, all IRF members, i.e. IRF1-11 with two IRF4, IRF4a and IRF4b have been characterised in an aquaculture species of fish, the mandarin fish, Siniperca chuatsi, in addition to the previous report of IRF1, IRF2, IRF3 and IRF7 from the fish. These IRFs are constitutively expressed in various organs/tissues of the fish, and their expression can be induced following the stimulation of polyinosinic:polycytidylic acid (poly(I:C)) and the infection of infectious spleen and kidney necrosis virus (ISKNV), a viral pathogen of mandarin fish in aquaculture. The ISKNV infection induced the significant increase in the expression of some IRF genes, i.e. IRF2, IRF4a, IRF7, IRF9, IRF10 at 24 or 36 h post-infection (hpi) in spleen and head-kidney, and the significant increase of some other IRF genes, e.g. IRF1, IRF3, IRF4b, IRF5, IRF6, IRF8 at later stage of infection from 72, or 96, or even 120 hpi, which may imply the inhibitory effect of ISKNV on fish immune response. It is considered that the present study provides the first detailed analysis on all IRF members in an aquaculture species of fish, and can be served as the base for further investigation on the role of IRFs in teleost fish. PMID- 29180034 TI - Surgical Stabilization of Rib Fractures: A Single Institution Experience. AB - BACKGROUND: Use of surgical stabilization of rib fractures (SSRF) has increased. Despite compelling small studies, many centers still struggle with determining criteria for intervention. We investigated the benefit of SSRF in our patients compared with nonoperative (NonOp) National Trauma Databank (NTDB) controls, specifically in the older population. STUDY DESIGN: We performed a retrospective comparison of trauma patients with >=3 and >5 rib fractures, who underwent SSRF at a tertiary care level I trauma center, with nonoperatively managed NTDB controls from equivalent level I centers between 2007 and 2014. The main outcomes measures included mortality, pneumonia, length of stay (LOS), ICU LOS, ventilator use, and tracheostomy rates. RESULTS: Overall, SSRF patients were older, had a higher percentage of respiratory disease, and higher Injury Severity Scores (ISS). Despite more respiratory disease in SSRF patients vs NonOp (p < 0.0001), there was no difference in ventilator usage. Results of SSRF included decreases in mortality (12%, p = 0.008) and pneumonia (13%, p < 0.001) compared with NonOp on propensity score matching. On subgroup analysis of patients 65 years of age or older, ISS was higher in the SSRF group. Mortality was significantly lower for SSRF vs NonOp, even with higher frequency of respiratory disease within the group (p < 0.001). CONCLUSIONS: Patients who underwent SSRF at our institution had improved outcomes despite a higher percentage of respiratory disease, compared with patients who were managed nonoperatively nationwide. Mortality rates improved for patients aged 65 and older, suggesting that this patient population may benefit more from SSRF. PMID- 29180033 TI - Bioluminescent tracing of a Yersinia pestis pCD1+-mutant and Yersinia pseudotuberculosis in subcutaneously infected mice. AB - Yersinia pestis has evolved from Yersinia pseudotuberculosis serotype O:1b. A typical Y. pestis contains three plasmids: pCD1, pMT1 and pPCP1. However, some isolates only harbor pCD1 (pCD1+-mutant). Y. pestis and Y. pseudotuberculosis share a common plasmid (pCD1 or pYV), but little is known about whether Y. pseudotuberculosis exhibited plague-inducing potential before it was evolved into Y. pestis. Here, the luxCDABE::Tn5::kan was integrated into the chromosome of the pCD1+-mutant, Y. pseudotuberculosis or Escherichia coli K12 to construct stable bioluminescent strains for investigation of their dissemination in mice by bioluminescence imaging technology. After subcutaneous infection, the pCD1+ mutant entered the lymph nodes, followed by the liver and spleen, and, subsequently, the lungs, causing pathological changes in these organs. Y. pseudotuberculosis entered the lymph nodes, but not the liver, spleen and lungs. It also resided in the lymph nodes for several days, but did not cause lymphadenitis or pathological lesions. By contrast, E. coli K12-lux was not isolatable from mouse lymph nodes, liver, spleen and lungs. These results indicate that the pCD1+-mutant can cause typical bubonic and pneumonic plague like diseases, and Y. pestis has inherited lymphoid tissue tropism from its ancestor rather than acquiring these properties independently. PMID- 29180036 TI - Sphingosine 1-phosphate regulates proliferation, cell cycle and apoptosis of hepatocellular carcinoma cells via syndecan-1. AB - Sphingosine 1-phosphate (S1P) plays an important role in hepatocarcinogenesis. We previously demonstrated that S1P induced epithelial-mesenchymal transition of hepatocellular carcinoma (HCC) cells via an MMP-7/Syndecan-1/TGF-beta autocrine loop. In the present study, we investigated the regulative role of S1P in cell survival and progression of HCC cells, and tested whether syndecan-1 is required in the S1P action. After transfected with syndecan-1 shRNA, HepG2 and SMMC7721 cells were treated with S1P for 72 h, and then cell proliferation was detected by CCK8 assay, and cell cycle progression and cell apoptosis were detected by flow cytometry. The levels of apoptosis markers including cleaved-Caspase-3 and cleaved-PARP in SMMC7721 cells were examined by western blotting. Results showed that S1P significantly enhanced cell proliferation in HCC cells, which was significantly inhibited by syndecan-1 shRNA. S1P induced the cell proportion in S phase in HCC cells, whereas S1P decreased the proportion of cells in both early and late apoptosis. Syndecan-1 shRNA induced the G2/M arrest in the presence of S1P. In the syndecan-1 shRNA transfected HCC cells, the proportions of late and early apoptotic cells, and levels of cleaved-Caspase-3 and cleaved-PARP were significantly increased in cells with or without S1P treatment. Thus, S1P augments the proportion of cells in S phase of the cell cycle that might translate to enhance HCC cell proliferation and inhibit the cell apoptosis via syndecan-1. PMID- 29180035 TI - Prevalence and characteristics of overweight and obesity among Chinese youth aged 12-18 years: a multistage nationwide survey. AB - OBJECTIVE: The aims of the current study were to assess the prevalence of overweight and obesity by four different references and to explore the characteristics of adolescent overweight and obesity in Chinese secondary school students aged 12-18 years. STUDY DESIGN: A cross-sectional study was conducted in this study. METHODS: Using stratified random cluster sampling, 8999 secondary school students were enrolled. The references developed by Must and Dallal and Dietz, the Childhood Obesity Working Group of the International Obesity Task Force, the US Centers for Disease Control and Prevention, and the Group of China Obesity Task Force (GCOTF reference) were used to identify overweight and obese students. RESULTS: The prevalence of adolescent overweight and obesity vary substantially based on the four references. The prevalence of adolescent overweight and obesity based on GCOTF reference are 8.4% and 4.1%, respectively, which is significantly lower than the prevalence of overweight and obesity in their peers in 2000 (chi2 = 24.03, P < 0.01). The prevalence of overweight and obesity in boys are 12.0% and 5.7%, which are higher than those in girls, 4.6% and 5.7% (chi2 = 240.68, P < 0.01). The prevalence of overweight and obesity in singletons are higher than those in non-singletons (chi2 = 40.25, P < 0.01). The prevalence of overweight and obesity in students with lower school community ladder of subjective social status are higher than those from higher ones (chi2 = 21.61, P < 0.01). CONCLUSION: The GCOTF reference is more suitable for screening overweight and obesity in Chinese adolescents. The current prevalence rates of adolescent overweight and obesity decreased, and girls made a tremendous contribution to this decreasing trend. Singletons and adolescents in lower school community ladder of subjective socio-economic status may be at higher risk of getting overweight and obesity. More effective strategies with full consideration to the characteristics above should be developed to control and prevent adolescent overweight and obesity. PMID- 29180037 TI - MIR-10b IS inversely correlated with higher tumor grade in osteosarcoma. PMID- 29180038 TI - Association of Multiple Phosphorylated Proteins with the 14-3-3 Regulatory Hubs: Problems and Perspectives. AB - 14-3-3 proteins are well-known universal regulators binding a vast number of partners by recognizing their phosphorylated motifs, typically located within the intrinsically disordered regions. The abundance of such phosphomotifs ensures the involvement of 14-3-3 proteins in sophisticated protein-protein interaction networks that govern vital cellular processes. Thousands of 14-3-3 partners have been either experimentally identified or predicted, but the spatiotemporal hierarchy of the processes based on 14-3-3 interactions is not clearly understood. This is exacerbated by the lack of available structural information on full regulatory complexes involving 14-3-3, which resist high-resolution structural studies due to the presence of intrinsically disordered regions. Although deducing three-dimensional structures is of particular urgency, structural advances are lagging behind the rate at which novel 14-3-3 partners are discovered. Here I attempted to critically review the current state of the field and in particular to dissect the unknowns, focusing on questions that could help in moving the frontiers forward. PMID- 29180039 TI - Regioselective ester cleavage of di-(2-ethylhexyl) trimellitates by porcine liver esterase. AB - In a comparative study the ester hydrolysis of the plasticizers di-(2-ethylhexyl) phthalate (DEHP) and tri-(2-ethylhexyl) trimellitate (TEHTM) as well as of the diester isomers 1,2-di-(2-ethylhexyl) trimellitate (1,2-DEHTM), 1,4-di-(2 ethylhexyl) trimellitate (1,4-DEHTM) and 2,4-di-(2-ethylhexyl) trimellitate (2,4 DEHTM) was investigated by a newly developed in vitro experimental design using porcine liver esterase (PLE). The substrates were incubated with PLE for 48h at 25 degrees C in borate buffer and samples were taken at predetermined intervals during the experiment. The samples were processed using liquid-liquid extraction and analyzed using LC-MS/MS. The results demonstrated a rapid and extensive hydrolysis of the diester DEHP to the monoester mono-(2-ethylhexyl) phthalate (MEHP) during the incubation with PLE. The isomers of DEHTM were also hydrolyzed by PLE to a high extent, whereas TEHTM showed a high stability against enzymatic hydrolysis. The regioselective analysis revealed that the monoester isomers 1 MEHTM and 2-MEHTM were predominantly produced during the degradation of DEHTM isomers, indicating a preferred hydrolysis at the para-position. These findings are eminent for planning further investigations on the human TEHTM metabolism, as the extent, rate and route of metabolism are of crucial importance for a toxicological assessment. PMID- 29180040 TI - Assessment of test method variables for in vitro skin irritation testing of medical device extracts. AB - Skin irritation is an important component of the biological safety evaluation of medical devices. This testing has typically been performed using in vivo models. However, in an effort to reduce the need for in vivo testing, alternative methods for assessing skin irritation potential in vitro have been developed using a Reconstructed Human Epidermis (RhE) model. During the development of the protocol for the round robin validation of in vitro irritation testing for medical device extracts, it became clear that there were three points in the procedure where different options may be validated within each laboratory for routine testing: sample exposure time (18 vs 24h), SDS positive control concentration, and cytokine (IL-1alpha) release testing. The goal of our study was to evaluate the effect of these variables. EpiDermTM tissues were exposed to extracts of three plain polymer samples, and four polymers embedded with known irritant chemicals. Exposures were performed for 18 and 24h. Resulting tissue viability was assessed by MTT reduction and IL-1alpha release was assessed by ELISA. Testing was also performed using various concentrations of SDS ranging from 0.5 to 1% (w/v). Overall, results were similar for samples tested and 18 and 24h, but the 18h exposure time has the potential to have an impact on the results of some sample types. IL-1alpha testing was shown to be useful to clarify conflicting tissue viability results. Use of a lower concentration of SDS as a positive control can help prevent issues that arise from excessive tissue damage often caused by 1% SDS. PMID- 29180041 TI - Moving Character Displacement beyond Characters Using Contemporary Coexistence Theory. AB - Character displacement is one of the most studied phenomena in evolutionary biology, yet research has narrowly focused on demonstrating whether or not displacement has occurred. We propose a new experimental approach, adopted from the coexistence literature, that directly measures interspecific competition among sympatric and allopatric populations of species. Doing so allows increased ability to (i) test predictions of character displacement without biases inherent to character-centric tests, (ii) quantify its effect on the stability of coexistence, (iii) resolve the phenotypic pathways through which competitive divergence is achieved, and (iv) perform comparative tests. Our approach extends research to forms of character displacement not readily identified by past methods and will lead to a broader understanding of its consequences for community structure. PMID- 29180042 TI - In vitro and in vivo anti-malignant melanoma activity of Alocasia cucullata via modulation of the phosphatase and tensin homolog/phosphoinositide 3-kinase/AKT pathway. AB - Alocasia cucullata, a Chinese herb, has been used as an anticancer treatment in southern China. Phosphatase and tensin (PTEN), is a tumor suppressor gene and the loss of PTEN expression may activate the phosphoinositide-3-kinase (PI3K)/AKT signaling pathway which play a key role in tumors formation and progression. In this study, we evaluated the anti-melanoma effect and the underlying mechanism of 50% ethanolic extract of A. cucullata (EAC) in vitro and in vivo. Using MTT, wound healing, and transwell assays, we found that EAC suppressed the proliferation, migration, and invasion of melanoma cells (B16-F10, A375 and A2058) in a dose-dependent manner. We also found that EAC suppresses B16-F10 tumor growth in a xenografted mouse model. Western blot analysis revealed that the expression level of PTEN was up-regulated, and phosphorylation of PI3K and AKT reduced in B16-F10 cells and tumor tissues after EAC treatment. No significant differences were observed in PI3K and AKT expression. Moreover, immunohistochemistry showed that the number of PTEN-positive cells in tumor tissues increased and that of p-AKT-positive cells decreased with EAC treatment, corroborating the western blot results. Our data reveal that EAC can inhibit malignant melanoma in vitro and in vivo and suggest that its anti-tumor effect is associated with modulation of the PTEN/ PI3K/AKT signaling pathway. In summary, our findings highlight a promising herbal remedy for the treatment of malignant melanoma, which warrants further study. PMID- 29180043 TI - Isolation and pharmacological characterization of a new cytotoxic L-amino acid oxidase from Bungarus multicinctus snake venom. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Bungarus multicinctus snake belongs to Elapidae family and is widely distributed in southern China. It is widely used in traditional Chinese medicine with the effect of dispelling wind and removing obstruction in the meridians. Moreover, it is also as a chief ingredient of many polyherbal formulations for the treatment of cancer. AIM OF THE STUDY: To evaluate the antitumor activity of Bungarus multicinctus snake venom components and isolate, characterize the most effective anti-tumor component of Bungarus multicinctus snake venom. MATERIALS AND METHODS: The in vitro antitumor activity of Bungarus multicinctus venom components was detected by cytotoxicity assay and cell apoptosis assay. A unique LAAO from Bungarus multicinctus venom named as BM Apotxin was isolated and characterized by Sephadex G-75 gel filtration, Sephadex G-25 desalting, Q ion-exchange chromatography and subsequent amino acids sequence determination. The LAAO activity and enzyme kinetics of BM-Apotxin was detected by microplate assay. RESULTS: BM-Apotxin, a 65KDa glycoprotein, which contributed to the most anti-tumor effects of Bungarus multicinctus venom. BM-Apotxin can selectively kill tumor cells, with less cytotoxicity to the normal cells. BM Apotxin is an L-amino acid oxidase (LAAO) with high sequence identity to other snake venom LAAOs. Its anti-tumor activity is mainly due to the hydrogen peroxide produced from LAAO oxidation. But the catalase did not reverse its anti-tumor effect completely. Like other snake venom LAAOs, BM-Apotxin can oxidize many L amino acids, not D amino acids. The optimum substrate for BM-Apotxin is L-Phe. Moreover, BM-Apotxin deglycosylation can significantly reduce the LAAO activity and anti-tumor activity of BM-Apotxin. CONCLUSION: This study will facilitate the study on anti-tumor mechanism of snake venom and drug development based on Bungarus multicinctus venom. PMID- 29180045 TI - Unraveling the human protein atlas of metastatic melanoma in the course of ultraviolet radiation-derived photo-therapy. AB - : To explore the photo-therapeutic capacity of UV radiation in solid tumors, we herein employed an nLC-MS/MS technology to profile the proteomic landscape of irradiated WM-266-4 human metastatic-melanoma cells. Obtained data resulted in proteomic catalogues of 5982 and 7280 proteins for UVB- and UVC-radiation conditions, respectively, and indicated the ability of UVB/C-radiation forms to eliminate metastatic-melanoma cells through induction of synergistically operating programs of apoptosis and necroptosis. However, it seems that one or more WM-266-4 cell sub-populations may escape from UV-radiation's photo-damaging activity, acquiring, besides apoptosis tolerance, an EMT phenotype that likely offers them the advantage of developing resistance to certain chemotherapeutic drugs. Low levels of autophagy may also critically contribute to the selective survival and growth of UV-irradiated melanoma-cell escapers. These are the cells that must be systemically targeted with novel therapeutic schemes, like the one of UV radiation and Irinotecan herein suggested to be holding strong promise for the effective treatment of metastatic-melanoma patients. Given the dual nature of UV radiation to serve as both anti-tumorigenic and tumorigenic agent, all individuals being subjected to risk factors for melanoma development have to be appropriately informed and educated, in order to integrate the innovative PPPM concept in their healthcare-sector management. SIGNIFICANCE: This study reports the application of nLC-MS/MS technology to deeply map the proteomic landscape of UV-irradiated human metastatic-melanoma cells. Data bioinformatics processing led to molecular-network reconstructions that unearthed the dual nature of UV radiation to serve as both anti-tumorigenic and tumorigenic factor in metastatic melanoma cellular environments. Our UV radiation-derived "photo-proteomic" atlas may prove valuable for the identification of new biomarkers and development of novel therapies for the disease. Given that UV radiation represents a major risk factor causing melanoma, a PPPM-based life style and clinical practice must be embraced by all individuals being prone to disease's appearance and expansion. PMID- 29180044 TI - Cell intrinsic characteristics of human cord blood naive CD4T cells. AB - It has been generally considered that the perinatal immune system is less inflammatory compared to the adult system and type 2 responses predominate perinatal immune responses against antigens. Indeed, previous studies in mice showed that there are cell-intrinsic differences between neonatal and adult CD4T cells. However, studies on human cord blood and infant blood demonstrated that human perinatal T cells do not produce elevated levels of Th2 cytokines with the exception of IL-13. These data raise the question if human T cells in the perinatal blood fundamentally differ from adult T cells. To decipher differences between human perinatal and adult T cells, we performed a focused comparative analysis on purified naive CD4T cells from umbilical cord blood (UCB) and adult peripheral blood. Our data demonstrate naive CD4T cells from UCB differ from adult naive CD4T cells in surface expression of CD26, dipeptidyl peptidase-4. While only a fraction of effector/memory T cells from adult blood express CD26, practically all T cells from UCB express high levels of CD26. We also determined that Th1/Th2 polarizing conditions induce UCB CD4T cells to produce higher levels of IFN-gamma and IL-5 compared to adult CD4T cells, respectively. These data demonstrate intrinsic differences between UCB and adult naive CD4T cells and suggest that human perinatal immune responses involve more complex mechanisms than the previously thought Th2-dominant responses. PMID- 29180046 TI - Proteomics in cardiovascular diseases: Unveiling sex and gender differences in the era of precision medicine. AB - : Cardiovascular diseases (CVDs) represent the most important cause of mortality in women and in men. Contrary to the long-standing notion that the effects of the major risk factors on CVD outcomes are the same in both sexes, recent evidence recognizes new, potentially independent, sex/gender-related risk factors for CVDs, and sex/gender-differences in the clinical presentation of CVDs have been demonstrated. Furthermore, some therapeutic options may not be equally effective and safe in men and women. In this context, proteomics offers an extremely useful and versatile analytical platform for biomedical researches that expand from the screening of early diagnostic and prognostic biomarkers to the investigation of the molecular mechanisms underlying CDVs. In this review, we summarized the current applications of proteomics in the cardiovascular field, with emphasis on sex and gender-related differences in CVDs. SIGNIFICANCE: Increasing evidence supports the profound effect of sex and gender on cardiovascular physio-pathology and the response to drugs. A clear understanding of the mechanisms underlying sexual dimorphisms in CVDs would not only improve our knowledge of the etiology of these diseases, but could also inform health policy makers and guideline committees in tailoring specific interventions for the prevention, treatment and management of CVDs in both men and women. PMID- 29180047 TI - Iron status and oxidative stress in the aged rabbit heart. AB - Altered iron status may be relevant to the pathophysiology of aging. We have assessed redox-active catalytic low molecular weight iron (LMWI), non-heme iron (NHI), heme iron (HI), and total iron (TI) in the aerobically perfused hearts of aged rabbits (AR, about 4.5years old) and young adult control rabbits (YACR, 3 4months old); myocardial lipid and protein oxidations were also assessed as oxidative stress biomarkers. The levels of LMWI and NHI, as well as of lipid and protein oxidation, were higher, while HI content was lower, in the hearts of AR than in those of YACR; TI did not differ significantly between the two groups. Together with these findings, hemodynamic dysfunction, namely heightened end diastolic pressure (EDP) and lowered coronary flow (CF), occurred in the AR hearts. Notably, such pattern of hemodynamic dysfunction associated with myocardial oxidant damage occurred in the hearts of other YACR perfused in the presence of a cell-permeable form of iron, i.e., the iron/hydroxyquinoline complex, pointing to the involvement of catalytic iron in the aged heart damage. Moreover, as shown in other AR, heart perfusion in the presence of the iron chelator deferoxamine (0.6mM or 3.6mM) reduced the myocardial levels of LMWI, without significantly affecting those of NHI, HI, and TI; concomitantly, in AR deferoxamine lowered myocardial lipid and protein oxidation, and reduced EDP with a tendency to augment CF. Instead, deferoxamine, even at high concentration of 3.6mM, had no significant effects in the YACR. In conclusion, altered iron status with catalytic LMWI burden occurs in the aged rabbit heart, eventually resulting in iron-dependent cardiac oxidative stress and hemodynamic dysfunction. PMID- 29180049 TI - Self-assembled supramolecular hydrogels formed by biodegradable PLA/CS diblock copolymers and beta-cyclodextrin for controlled dual drug delivery. AB - The supramolecular hydrogel based on inclusion complexation between PLA/CS diblock copolymer and beta-CD has been demonstrated. The PLA/CS diblock copolymer confirmed by FIIR and 1HNMR were synthesized by in situ polymerization. The supramolecular hydrogel formed due to the complexation of PLA/CS with beta cyclodextrin was demonstrated by XRD and FIIR analysis. These results indicate that the carbonyl groups of PLA can form hydrogen bonds with the hydroxyl groups of beta-CD and CS in the complexes. The supramolecular hydrogel presented a porous network structure observed by positive fluorescence microscopy (PFM) was found to be thixotropic and reversibl. The gel kinetics has been studied by monitored the viscosity of the supramolecular system, which was well illustrated according to the Stokes-Einstein equation. The in vitro release kinetics studies of the two model drug from the hydrogel show the co-encapsulation of heparin sodium (HPS) and bovine serum albumin (BSA) exhibits better sustained release behaviors. Furthermore, the release rate of HPS is lower than that of BSA was explored by the two-dimensional UV correlation spectroscopy. The supramolecular hydrogel can be formulated to be a promising candidate for controlled dual drug delivery systems. PMID- 29180048 TI - Proteolytic and amylolytic enzymes from a newly isolated Bacillus mojavensis SA: Characterization and applications as laundry detergent additive and in leather processing. AB - The present work aims to study the simultaneous production of highly alkaline proteases and thermostable alpha-amylases by a newly isolated bacterium Bacillus mojavensis SA. The optimum pH and temperature of amylase activity were 9.0 and 55 degrees C, respectively, while those of the proteolytic activity were 12.0 and 60 degrees C, respectively. Both alpha-amylase and protease enzymes showed a high stability towards a wide range of pH and temperature. Furthermore, SA crude enzymes were relatively stable towards non-ionic (Tween 20, Tween 80 and Triton X 100) and anionic (SDS) surfactants, as well as oxidizing agents. Both activities were improved by the presence of polyethylene glycol 4000 and glycerol. Additionally, the crude enzymes showed excellent stability against various solid and liquid detergents. Wash performance analysis revealed that the SA crude enzymes exhibited a remarkable efficiency in the removal of a variety type of stains, such as blood, chocolate, coffee and oil. On the other side, SA proteases revealed a potential dehairing activity of animal hide without chemical assistance or fibrous proteins hydrolysis. Thus, considering their promising properties, B. mojavensis SA crude enzymes could be used in several biotechnological bioprocesses. PMID- 29180050 TI - Potential of Potentilla inclinata and its polyphenolic compounds in alpha glucosidase inhibition: Kinetics and interaction mechanism merged with docking simulations. AB - In the present study we aimed to identify the alpha-glucosidase enzyme inhibitory potential of Potentilla inclinata Vill. MeOH and n-BuOH extracts which possessed remarkable alpha-glucosidase enzyme inhibitory effects with IC50 values of 1.06+/ 0.02 and 0.93+/-0.01MUg/ml respectively, compared to that of acarbose (IC50 31.92+/-0.17). Thus, BuOH extract was chosen for further phytochemical investigations. A phenolic acid, six flavonol glycosides, and two hydrolysable tannins were isolated from the most active n-BuOH extract of the title plant. Structures of the isolated compounds were elucidated by 1D- and 2D-NMR experiments. All the compounds exhibited remarkable alpha-glucosidase inhibitory activity compared to the positive control, acarbose. Rutin (2) showed the highest activity with an IC50 value of 26.31+/-0.02MUg/ml. An enzyme kinetics analysis revealed that compounds 5 and 7 were competitive, 4 and 6 noncompetitive, and 3 was uncompetitive inhibitors of alpha-glucosidase enzyme. Molecular docking studies were performed to get insights into inhibition mechanisms of the isolates considering their inhibition type using various binding sites of the enzyme model we previously reported. PMID- 29180051 TI - Aptamer based assay of plated-derived grow factor in unprocessed human plasma sample and MCF-7 breast cancer cell lysates using gold nanoparticle supported alpha-cyclodextrin. AB - Platelet-derived growth factor (PDGF), a protein biomarker, is directly involved in many cell transformation processes, such as tumor growth and progression. Elevation platelet-derived growth factor (PDGF-BB) concentration in plasma could indicate the accelerating growth of metastatic breast tumors and angiogenesis. The development of an apta-assay for detection of PDGF-BB in is presented in this work. A highly specific DNA-aptamer, selected to PDGF-BB was immobilized onto a gold nanoparticles supported alpha-cyclodextrin and electrochemical measurements were performed in a solution containing the phosphate buffer solution with physiological pH. Variety of shapes of gold nanostructures with different sizes from zero-dimensional nanoparticles to spherical structures were prepared by one step template (alpha-cyclodextrin)-assistant green electrodeposition method. Fully electrochemical methodology was used to prepare a new transducer on a gold surface which provided a high surface area to immobilize a high amount of the aptamer. The surface morphology of electrode was characterized by high-resolution field emission scanning electron microscope (FE-SEM) and energy dispersive spectroscopy (EDX). The prepared aptasensors represented different electrochemical activities toward the redox processes of PDGF-BB attributing to the size and shape of the gold nanoparticles. The aptasensor was employed for the detection of PDGF using square wave voltammetry (SWV) and Cyclic voltammetry (CV) techniques. Under optimized condition the calibration curve for PDGF-BB was linear in 0.52-1.52nM with low limit of quantification of 0.52nM. Also, under the optimized experimental conditions, the proposed aptasensor of GNPs-cubic-alpha-CD Apt-Au electrode exhibited excellent analytical performance for MCF-7 cells determination, ranging from 328 TO 593 cells mL-1 with low limit of quantification of 328 cells mL-1. As a result, the electrochemical aptasensor was able to detect cancer-related targets in unprocessed human plasma samples.

AB - Tyrosinase (EC 1.14.18.1) is a key copper-containing metalloenzyme widely distributed in nature and plays determinant role in melanin biosynthesis. The enzyme manifests two unusual catalytic properties including oxidase and monooxygenase activities. Its inhibitors may be applied to efficiently treat of hyperpigmentation and widely used in pharmaceutical and cosmetic products, as well as food supplements and insecticides. The present study aims to evaluate the inhibitory effects of some novel azo-hydrazone tautomeric dyes (4a-e) including bioactive thiazolidinone moiety on the activity of the mushroom tyrosinase. When L-3,4-dihydroxyphenylalanine (L-Dopa) was used as the substrate for the enzyme, the compounds 4d, 4a, and 4e showed strong inhibitory effects against the activity of the enzyme (61%, 56%, and 49% inhibition in the presence of 60MUM of each compound, respectively). The IC50 values of the synthetized compounds were measured and their inhibition properties were also visualized by zymography. According to tyrosinase inhibitory activity, the compounds 4a, 4c, 4d and 4e exhibited strong inhibitory activities with IC50 values of 45.83, 140.25, 37.59, and 42.31MUM, respectively, compared to the positive control kojic acid (29.44MUM). Kinetic study of 4d compound (as the most potent inhibitor) revealed that the compound acts as a reversible competitive inhibitor of the enzyme with the Ki value of 31.0MUM. We also simulated the molecular docking with the compound 4d and the results confirmed that the compound strongly interacts with the mushroom tyrosinase residues. All results totally suggest that thiazolidine derivatives, especially 4d, 4a, and 4e, can be considered as safe and efficient tyrosinase inhibitors. They also have the potential to be used in the correspond fields. PMID- 29180053 TI - Unique properties of arginase purified from camel liver cytosol. AB - Arginase (ARG) is an enzyme involved in urea cycle, where it catalyzes the hydrolysis of L-arginine into L-ornithine and urea. Since there is no information about the isolation and purification of ARG from camel liver, this investigation was designed to purify and characterize ARG from camel liver and compare its molecular and kinetic properties with that reported from other species. Camel liver arginase (CL-ARG) was purified to homogeneity using heat denaturation followed by ammonium sulphate precipitation with a combination of DEAE-cellulose, SP-Sepharose and Sephadex G 100-120 chromatography columns. The specific activity of CL-ARG was increased to 18,485 units/mg proteins with 23.5-fold purification over crude homogenate. It was observed that CL-ARG showed a similarity with other species such as behaviour on DEAE-cellulose column, kinetics of inhibition, necessity for metal ions as cofactor, and alkaline optimum pH. On the contrary, CL-ARG differed in its molecular weight (180kDa), oligomeric protein structure, slightly neutral-alkaline pI value (7.7), Km value (7.1mM), optimum pH (9, 10.7), and higher optimum temperature (70 degrees C). In conclusion, this study investigated the properties of CL-ARG via a simple and reproducible purification procedure and provided valuable information for its production from available source in Egypt for medical and industrial purposes. PMID- 29180054 TI - [A therapeutic education program for parents of children with ASD: Preliminary results about the effectiveness of the ETAP program]. AB - Autism Spectrum Disorders (ASD) are characterized by particularities of cognitive and socio-adaptive functioning. Daily, they require specific interventions for the disabled person as well as support for parents who often report deterioration in their physical and mental health. To this end, the latest Autism Plan 2013 2017 highlights the need "to help families to be present and active alongside their loved ones, to avoid situations of exhaustion and stress and to enable them to play their role fully in the long term". The support devices must therefore be based on an analysis of the parents' needs and propose multiple intervention modalities, which respond to the complexity of the caregiving mission. Therapeutic education (TE) seems to answer to these different elements by proposing a global approach improving the development of child-centered skills and the educational challenges (self-care skills) but also of skills centered on the projects and the fulfillment of the parent (psychosocial skills). The ETAP (Therapeutic Education Autism and Parenting) program is an initial TE offer intended for parents of children with ASD aged between 3 and 10years. It consists of seven group sessions and two semi-structured interviews, called educational diagnosis. A booster session is also proposed three months after the last session. It was developed following rigorously the guidelines on program construction, published by the High Authority of Health. In addition, it is based on an assessment of the needs of the parents, an in-depth analysis of the literature and the opinion of nine experts in this area. The objective of this study is to evaluate the effectiveness of the ETAP program on the quality of life and anxio-depressive symptoms of parents of a child with ASD. To our knowledge, the ETAP program is the first TE program in France for parents of children with an ASD that has been evaluated. Our sample is composed of 40 participants, including 30 parents who participated in the ETAP program ("ETAP Group"), compared to ten controls who did not participate, but who are on a waiting list ("Control Group"). Each participant completed a Quality of Life Questionnaire (WhoQol-Brief) and an Anxiety-Depressive Symptomatology Questionnaire (HADS) prior to the start of the program (T1) and after the session 7 (T2). Preliminary analyses show a good intergroup matching on socio-demographic and medical data. Moreover, the two groups are not significantly different at T1 over the set of dependent variables measured. Our results show an improvement in the quality of life of the depressive symptomatology in the participants. On the other hand, we did not notice any significant decrease in anxiety symptoms. However, when we consider the proportion of parents with a significant anxiety state (in terms of the clinical threshold of HADS, score >=10), we see that it tends to decrease after the program only for the group ETAP. These data should be interpreted with caution because of their preliminary nature and the small size of our sample. However, the first steps are encouraging and confirm the value of the therapeutic education model for parents of children with ASD. The different information given during the sessions takes into account the previous representations, knowledge and skills of the parent. Thus the program promotes the upholding and the development of individual resources in parents. In addition, the psychosocial skills targeted also to make access easier to available environmental resources. Finally, in a more indirect way, the ETAP program also aims to maintain or restore a positive parenthood and individual identity and the progressive development of new ways of to interact with the environment. An adaptation of the Hobfoll resource conservation model is proposed by the authors to formulate hypotheses on the mechanisms of action of the ETAP program. PMID- 29180055 TI - UPRmt coordinates immunity to maintain mitochondrial homeostasis and animal fitness. AB - Proper function of mitochondria is often challenged by intrinsic factors and extrinsic stimuli. To cope with mitochondrial stress, organisms evolve mitochondrial unfolded protein response (UPRmt) to monitor mitochondrial function and induce the transcription of mitochondrial chaperones and proteases to restore mitochondrial proteostasis and alleviate stress. Interestingly, UPRmt also induces immune response genes and improves animals' fitness against pathogen infection. In this review, we will summarize progresses of UPRmt studies and discuss the relationship between UPRmt and the induction of innate immunity. PMID- 29180056 TI - Controversy and debate on dengue vaccine series-paper 1: review of a licensed dengue vaccine: inappropriate subgroup analyses and selective reporting may cause harm in mass vaccination programs. AB - Severe life-threatening dengue fever usually occurs when a child is infected by dengue virus a second time. This is caused by a phenomenon called antibody dependent enhancement (ADE). Since dengue vaccines can mimic a first infection in seronegative children (those with no previous infection), a natural infection later in life could lead to severe disease. The possibility that dengue vaccines can cause severe dengue through ADE has led to serious concern regarding the safety of mass vaccination programs. A published meta-analysis addressed this safety issue for a new vaccine against dengue fever-Dengvaxia. The trials in this meta-analysis have been used to campaign for mass vaccination programs in developing countries. We discuss the results of this paper and point out problems in the analyses. Reporting the findings in an Asian trial (CYD14), the authors show a sevenfold rise in one outcome-hospitalization for dengue fever in children <5 years old. However, they fail to point out two signals of harm for another outcome-hospitalization for severe dengue fever (as confirmed by an independent data monitoring committee): 1. In children younger than 9 years, the relative risk was 8.5 (95% confidence interval [CI]: 0.5, 146.8), and 2. In the overall study group, the relative risk was 5.5 (95% CI: 0.9, 33). The authors conduct a subgroup analysis to support claims that the vaccine is probably safe among children aged 9 years or more. This subgroup analysis has limited credibility because: (1) it was a post hoc analysis; (2) it was one of a large number of subgroup analyses; (3) the test of interaction was not reported, but was insignificant (P = 0.14); and (4) there is no biological basis for a threshold age of 9 years. The more likely explanation for the higher risk in younger children is ADE, that is, more frequent seronegativity, rather than age itself. The selective reporting and inappropriate subgroup claims mask the potential harm of dengue mass vaccination programs. Countries planning public use of the vaccine must conduct diligent postmarketing surveillance, secure informed consent from parents of potential recipients, and closely monitor the results of ongoing long term follow-up of clinical trial participants. PMID- 29180057 TI - Do Live Discharge Rates Increase as Hospices Approach Their Medicare Aggregate Payment Caps? AB - CONTEXT: The rate of live discharge from hospice and the proportion of hospices exceeding their aggregate caps have both increased for the last 15 years, becoming a source of federal scrutiny. The cap restricts aggregate payments hospices receive from Medicare during a 12-month period. The risk of repayment and the manner in which the cap is calculated may incentivize hospices coming close to their cap ceilings to discharge existing patients before the end of the cap year. OBJECTIVE: The objective of this work was to explore annual cap-risk trends and live discharge patterns. We hypothesized that as a hospice comes closer to exceeding its cap, a patient's likelihood of being discharged alive increases. METHODS: We analyzed monthly hospice outcomes using 2012-2013 Medicare claims. RESULTS: Adjusted analyses showed a positive and statistically significant relationship between cap risk and live discharges. CONCLUSION: Policymakers ought to consider the unintended consequences the aggregate cap may be having on patient outcomes of care.

AB - Malpighia glabra L. is indicated for the treatment of diseases due presenting several medicinal properties. The aim of the present study was quantify phenolic compounds and carotenoids, additionally, evaluate the antioxidant potential of different methanolic fractions (mature stage, intermediate stage and green maturity stage) of Malpighia glabra. Methanolic fractions of the three stages of maturation were characterized using HPLC-DAD. The antioxidant activity of fractions was evaluated using in vitro assay systems: iron-chelating activity (Fe2+), inhibition of the radical 1-1-diphenyl-2-picrylhydrazyl (DPPH) and inhibition of production of thiobarbituric acid reactive substances (TBARS). In quantifying compounds by HPLC-DAD showed that the compounds rutin and quercetin showed the highest peaks in the three samples tested. Regarding carotenoids, the beta-carotene stood in the analyze. The methanolic fraction of lyophilized pulp of green fruits showed better results for iron chelation and DPPH tests; TBARS by the methanolic fraction of the ripe fruits showed lower IC50 as the basal. When in the presence of iron as an inducer of peroxidation, the methanolic fraction of the pulp of green fruits showed the lowest IC50. Our research indicates that the o fruits of M. glabra good potential in scavenging free radicals and can be an important source of antioxidant phytochemical. PMID- 29180062 TI - Metabolic detoxification of bakuchiol is mediated by oxidation of CYP 450s in liver microsomes. AB - Bakuchiol, one of bioactive compounds isolated from the dried ripe fruits of Psoralea corylifolia L., possesses a variety of pharmacological activities. In this study, the metabolites of bakuchiol in rat liver microsomes as well as their cytotoxicities were studied. A total of eight metabolites were isolated and identified as 14-carboxylbakuchiol (M1), 14,15-dihydroxybakuchiol (M2), 12,13 dihydroxybakuchiol (M3), 15-hydroxybakuchiol (M4), 14-hydroxybakuchiol (M5), bakuchiol hydrate (M6), 15-hydroxybakuchiol acetate (M7), and 14-hydroxybakuchiol acetate (M8). All the metabolites are new compounds except for M3. The main type of biotransformation is oxidation reaction, including hydroxylation, epoxidation and carboxylation. Cytotoxicities of bakuchiol and its metabolites against human kidney-2 (HK-2) cell line were evaluated. The median inhibition concentration (IC50) values of bakuchiol, M4, M6 and M8 were (29.48 +/- 0.22) MUM, (67.51 +/- 6.80) MUM, (90.23 +/- 3.89) MUM, and (86.62 +/- 6.08) MUM, respectively, and the IC50 values of M1, M2, M3, M5, and M7 were all in excess of 100 MUM. To further verify the metabolic reliability, the metabolits of bakuchiol in vivo and the metabolic species variations in human and rat liver microsomes were studied using UPLC-MS/MS method. This study provides valuable information for further investigation of metabolism and toxicity of bakuchiol in vivo.

PMID- 29180064 TI - Exposure to bisphenol S alters the expression of microRNA in male zebrafish. AB - Bisphenol S (BPS), an alternative compound of bisphenol A, has been found to affect reproduction, development, and immune system. Although microRNAs (miRNAs) play an important role in many metabolic activities, whether and how they are involved in the process of BPS-induced toxicity is unknown. In the present study, BPS-induced changes in miRNAs and target gene expression in male zebrafish gonad, and the potential mechanism was investigated. Male zebrafish were exposed to 0, 5, and 50MUg/L BPS for 21 d. miRNA was isolated from the gonad pool and the expression profiles of 255 known zebrafish miRNAs were analyzed using microarrays. Quantitative real-time polymerase chain reaction was used to validate the expression of several miRNAs in the microarray data. The GO term analysis revealed that miRNAs significantly affected by BPS exposure were involved in hematopoiesis, lymphoid organ development, and immune system development. Among 14 miRNAs that were significantly regulated after exposure to 5 and 50MUg/L BPS, six targeted cyp19a1b gene, suggesting the role of BPS-induced toxicity via the interference with the aromatization process. Our findings provide novel insight into the epigenetic regulatory mechanisms of BPS-induced toxicity in male zebrafish, and identification of novel miRNA biomarkers for exposure to BPS. PMID- 29180065 TI - beta-Naphthoflavone treatment attenuates neonatal hyperoxic lung injury in wild type and Cyp1a2-knockout mice. AB - Exposure to supraphysiological concentrations of oxygen (hyperoxia) leads to bronchopulmonary dysplasia (BPD), one of the most common pulmonary morbidities in preterm neonates, which is more prevalent in males than females. Beta naphthoflavone (BNF) is protective against hyperoxic lung injury in adult and neonatal wild type (WT) mice and in and mice lacking Cyp1a1gene. In this investigation, we tested the hypothesis that BNF treatment will attenuate neonatal hyperoxic lung injury in WT and Cyp1a2-/- mice, and elucidated the effect of sex-specific differences. Newborn WT or Cyp1a2-/- mice were treated with BNF (10mg/kg) or the vehicle corn oil (CO) i.p., from postnatal day (PND) 2 to 8 once every other day, while being maintained in room air or hyperoxia (85% O2) for 14days. Hyperoxia exposure lead to alveolar simplification and arrest in angiogenesis in WT as well as Cyp1a2-/- mice No significant differences were seen between WT and Cyp1a2-/- mice. Cyp1a2-/- female mice had better preservation of pulmonary angiogenesis at PND15 compared to similarly exposed males. BNF treatment attenuated lung injury and inflammation in both genotypes, and this was accompanied by a significant induction of hepatic and pulmonary CYP1A1 in WT but not in Cyp1a2-/- mice. BNF treatment increased NADPH quinone oxidoreductase (NQO1) mRNA levels in Cyp1a2-/- mouse livers compared to WT mice. These results suggest that BNF is protective in neonatal mice exposed to hyperoxia independent of CYP1A2 and this may entail the protective effect of phase II enzymes like NQO1. PMID- 29180066 TI - Inhibition of estrogen receptor reduces connexin 43 expression in breast cancers. AB - Connexins are widely supported as tumor suppressors due to their downregulation in cancers, nevertheless, more recent evidence suggests roles for connexins in facilitating tumor progression in later stages, including metastasis. One of the key factors regulating the expression, modification, stability, and localization of connexins is hormone receptors in hormone-dependent cancers. It is reasonable to consider that hormones/hormone receptors may modulate connexins expression and play critical roles in the cellular control of connexins during breast cancer progression. In estrogen receptor (ER)-positive breast cancers, tamoxifen and fulvestrant are widely used therapeutic agents and are considered to alter ER signaling. In this present study, we investigated the effects of fulvestrant and tamoxifen in Cx43 expression, and we also explored the role of Cx43 in ER positive breast cancer migration and the relationship between Cx43 and ER. The involvement of estrogen/ER in Cx43 modulation was further verified by administering tyrosine kinase inhibitors and chemotherapeutic agents. We found that inhibition of ER promoted the binding of E3 ligase Nedd4 to Cx43, leading to Cx43 ubiquitination. Furthermore, inhibition of ER by fulvestrant and tamoxifen phosphorylated p38 MAPK, and inhibition of Rac, MKK3/6, and p38 reversed fulvestrant-reduced Cx43 expression. These findings suggest that Cx43 expression which may positively regulate cell migration is ER-dependent in ER-positive breast cancer cells. PMID- 29180067 TI - "Sports Ultrasound", advantages, indications and limitations in upper and lower limbs musculoskeletal disorders. Review article. AB - Ultrasonography (US) is a safe and noninvasive imaging modality that is gaining popularity in different medical and surgical fields. Its introduction in musculoskeletal and sports medicine has taken this advanced subspecialty to a higher level. It has the advantage over other imaging techniques with regards to ease of use, availability, comfort and cost. Not to mention, in terms of safety profile, patients are not exposed to radiations, like in x-rays, and it can be performed on patients with metal or pacemaker implants, which are contraindicated in MRI. Standard diagnostic sonography doesn't have any known harmful effects on humans. In this article we will discuss the role of ultrasound in sports medicine, highlighting the diagnostic and interventional indications, uses and limitations. PMID- 29180068 TI - Timing of surgery for aneurysmal subarachnoid hemorrhage: A systematic review and meta-analysis. AB - INTRODUCTION: The timing of surgery for aneurysmal subarachnoid hemorrhage influences the outcome, but the optimal timing remains controversial. We conducted a systematic review to clarify whether early surgery was better than late surgery for improving outcome. MATERIALS AND METHODS: We systematically searched several databases to screen eligible studies. After synthesizing data, an overall effect was shown using a risk ratio (RR) and 95% confidence interval (CI). Subgroup analyses were stratified by multiple variables to control the confounding factors. Sensitivity analyses were applied to check the robustness of the results. Publication bias was measured with Egger's and Begg's tests. RESULTS: A total of 14 studies were included in the analysis. Compared with late surgery, early surgery significantly decreased the incidence of poor outcome, regardless of whether patients were in good condition (RR, 0.65 [95%CI, 0.50 0.84]; p = 0.001) or in poor condition on admission (RR, 0.71 [95%CI, 0.61 0.83]; p < 0.0001). Moreover, when patients were in good condition on admission, early surgery also effectively reduced the death rate (RR, 0.61 [95%CI, 0.46 0.82]; p = 0.001). Additionally, early surgery reduced the death rate compared with late surgery in patients older than 50 years (RR, 0.49 [95%CI, 0.27 0.89]; p < 0.002). CONCLUSIONS: Early surgery was superior to late surgery in reducing a poor outcome and death rate when patients were in good condition on admission, and decreased the incidence of poor outcome when patients were in poor condition on admission. Age was a potential confounding factor, influencing the effect of early surgery. Further study is required on this issue.

AB - Thromboxane A2 (TxA2) plays a very important role in various cardiovascular diseases through its action on platelet aggregation, vasoconstriction, and proliferation. The present article focuses on the role of TxA2 signaling in endothelium-dependent contractions of arteries. Arachidonic acid (AA) is metabolized by cyclooxygenase (COX) to form the unstable prostaglandin H2 which is further converted into TxA2. After being produced by thromboxane synthase (TxAS), TxA2 ultimately stimulates TxA2/prostanoid (TP) receptor to induce vasoconstriction. The calcium ionophore A23187, the prostanoid precursor AA, or the muscarinic receptor agonist acetylcholine (ACh) can evoke endothelium dependent contractions associated with TxA2. The endothelium-dependent contractions shown in hypertension, diabetes, atherogenesis, and other cardiovascular diseases have been significantly reduced by antagonism of COX, TxAS, or TP receptor. So inhibition of the bioavailability and/or effect of TxA2 may be promising therapeutic targets to prevent these diseases. Especially some bioactive compounds isolated from medicinal plants will provide new pharmacological approaches to promote vascular health. PMID- 29180072 TI - Functional Outcome of Completely Intracorporeal Robotic Ileal Ureteric Replacement. AB - OBJECTIVE: To assess perioperative, clinical, and functional outcomes following completely robotic ileal ureter. METHODS: We retrospectively reviewed 7 consecutive patients undergoing completely intracorporeal ileal ureteric replacement between November 2015 and May 2017. One patient had a solitary kidney. A 4-arm technique was used. In 5 patients, additional psoas hitch procedure was performed. Patients had retrograde filling and removal of the ileal stent and transurethral catheter at an average of 14 days postoperatively. Renal ultrasonography, serum analysis, and diuretic renography were performed at follow up 3 months postoperatively. RESULTS: Mean operative time was 328 +/- 66.3 minutes and median estimated blood loss was 100 mL (range 50-200); mean length of the ileal substitute was 20.4 cm (range 18-24). No case was converted to open surgery. In 1 patient, there was a prolonged insufficiency of the pyeloileal anastomosis, requiring prolonged stenting. Apart from that, there were no major complications and no open surgical or endoscopic reinterventions. On 3-month follow-up, all patients presented symptom-free, with no signs of obstruction on ultrasound and significantly improved glomerular filtration rate, creatinine levels, and differential renal function (P = .02, 0.03, and 0.046, respectively). Five patients had a diuretic halftime <10 minutes, 2 had a halftime between 10 and 20 minutes. CONCLUSION: Completely intracorporeal robotic ileal ureteric replacement results in full functional restoration of the upper tract in cases of long defects of the mid and upper ureter. PMID- 29180073 TI - Assessing the potential impact of a front-of-pack nutritional rating system on food availability in school canteens: A randomised controlled trial. AB - BACKGROUND: Front-of-pack graphical nutritional rating of products is becoming an important strategy in many countries to improve healthy food purchases by consumers. Evidence of the effectiveness of such on facilitating healthy food choices by school food service providers has not been reported. The primary aim of the study was to assess the impact of providing front-of-pack nutritional rating information on school canteen managers' likely food selections. Secondary outcomes were canteen manager awareness, attitudes and reported barriers to using the front-of-pack information. METHODS: A randomised controlled trial involving primary school canteen managers was conducted in a single region in New South Wales, Australia. Eligible participants were randomised to an intervention or control group and asked in a telephone interview which of 12 common food products sold in school canteens they would sell. Both groups received product name and brand information. The intervention group also received information regarding the nutritional rating of products. RESULTS: Canteen managers in the intervention group were significantly more likely than those in the control group to indicate they would sell three of the six 'healthier' products (p = 0.036, 0.005, 0.009). There was no difference between groups in the likelihood of making available for sale any of the six 'less healthy' products. The majority of canteen managers who had heard of a product nutritional rating system agreed that it was helpful in identifying 'healthier' foods (88%, n = 31). CONCLUSIONS: The inclusion of product nutritional rating information has the potential to improve the availability of some 'healthier' items on canteen menus and contribute to improving child dietary intake. Further research is required to determine whether the use of product nutritional rating information actually makes a difference to canteen manager choices. PMID- 29180070 TI - A high-throughput screening campaign to identify inhibitors of DXP reductoisomerase (IspC) and MEP cytidylyltransferase (IspD). AB - The rise of antibacterial resistance among human pathogens represents a problem that could change the landscape of healthcare unless new antibiotics are developed. The methyl erythritol phosphate (MEP) pathway represents an attractive series of targets for novel antibiotic design, considering each enzyme of the pathway is both essential and has no human homologs. Here we describe a pilot scale high-throughput screening (HTS) campaign against the first and second committed steps in the pathway, catalyzed by DXP reductoisomerase (IspC) and MEP cytidylyltransferase (IspD), using compounds present in the commercially available LOPAC1280 library as well as in an in-house natural product extract library. Hit compounds were characterized to deduce their mechanism of inhibition; most function through aggregation. The HTS workflow outlined here is useful for quickly screening a chemical library, while effectively identifying false positive compounds associated with assay constraints and aggregation. PMID- 29180074 TI - Sweet taste of prosocial status signaling: When eating organic foods makes you happy and hopeful. AB - As the current research suggests that there are links between prosocial acts and status signaling (including sustainable consumer choices), we empirically study (with three experiments) whether food consumers go green to be seen. First, we examine how activating a motive for status influences prosocial organic food preferences. Then, we examine how the social visibility of the choice (private vs. public) affects these preferences. We found that when consumers' desire for status was elicited, they preferred organic food products significantly over their nonorganic counterparts; making the choice situation visible created the same effect. Finally, we go beyond consumers' evaluative and behavioral domains that have typically been addressed to investigate whether this (nonconscious) "going green to be seen" effect is also evident at the level of more physiologically-driven food responses. Indeed, status motives and reputational concerns created an improved senso-emotional experience of organic food. Specifically, when consumers were led to believe that they have to share their organic food taste experiences with others, an elevation could be detected not only in the pleasantness ratings but also in how joyful and hopeful they felt after eating a food sample. We claim that the reason for this is that a tendency to favor organic foods can be viewed as a costly signaling trait, leading to flaunting about one's prosocial tendencies. According to these findings, highlighting socially disapproved consumption motives, such as reputation management, may be an effective way to increase the relatively low sales of organic foods and thereby promote sustainable consumer behavior.

AB - Cortex neuromodulation is promising approach for treatment of some neurological conditions, especially neuropathic pain and Parkinson's disease. Effects of non invasive cortical stimulation are short lived; transcranial direct current stimulation (tDCS) and transcranial alternating current stimulation (tACS) may be useful to assess the suitability for invasive cortical stimulation. Direct cortical stimulation (DCS) is the method able to provide long-lasting effects in treatment of neuropathic pain and some symptoms of Parkinson's disease through the use of totally implantable systems that ensure a chronic stimulation.

AB - PURPOSE: Few studies have reported large inter-observer variations in target volume selection and delineation in patients treated with radiotherapy for head and neck squamous cell carcinoma. Consensus guidelines have been published for the neck nodes (see Gregoire et al., 2003, 2014), but such recommendations are lacking for primary tumour delineation. For the latter, two main schools of thoughts are prevailing, one based on geometric expansion of the Gross Tumour Volume (GTV) as promoted by DAHANCA, and the other one based on anatomical expansion of the GTV using compartmentalization of head and neck anatomy. METHOD: For each anatomic location within the larynx, hypopharynx, oropharynx and oral cavity, and for each T-stage, the DAHANCA proposal has been comprehensively reviewed and edited to include anatomic knowledge into the geometric Clinical Target Volume (CTV) delineation concept. A first proposal was put forward by the leading authors of this publication (VG and CG) and discussed with opinion leaders in head and neck radiation oncology from Europe, Asia, Australia/New Zealand, North America and South America to reach a worldwide consensus. RESULTS: This consensus proposes two CTVs for the primary tumour, the so called CTV-P1 and CVT-P2, corresponding to a high and lower tumour burden, and which should be associated with a high and a lower dose prescription, respectively. CONCLUSION: Implementation of these guidelines in the daily practice of radiation oncology should contribute to reduce treatment variations from clinicians to clinicians, facilitate the conduct of multi-institutional clinical trials, and contribute to improved care of patients with head and neck carcinoma. PMID- 29180077 TI - Expression of CD133 as a Putative Prognostic Biomarker to Predict Intracranial Dissemination of Primary Spinal Cord Astrocytoma. AB - OBJECTIVE: Spinal cord astrocytoma with intracranial dissemination carries a poor prognosis. The mechanisms leading to dissemination remain to be elucidated. A stem cell marker, CD133, was reported to predict recurrence patterns in intracranial glioblastoma. We evaluated the significance of CD133 as a putative prognostic biomarker to predict intracranial dissemination in spinal cord astrocytoma. METHODS: This study included 14 consecutive patients with primary spinal cord astrocytoma treated from 1998 to 2014. Six of the patients were women and the patients' ages ranged from 12 to 75 years. Seven and 6 patients underwent open biopsy and partial resection of the tumors, respectively. After confirmation of the histologic diagnoses, all patients were treated with postoperative radiotherapy, chemotherapy, or a combination of both. To identify factors predictive of intracranial dissemination, we analyzed their clinical data including Ki-67 labeling index, and CD133 expression. RESULTS: Intracranial dissemination was observed in 6 of 14 patients. All 6 patients died during the follow-up period. Of the 8 patients without intracranial dissemination, 5 survived (P = 0.02). Median survival for the patients with intracranial dissemination was 22.7 months. CD133 expression was significantly higher in patients with intracranial dissemination (P = 0.04), whereas other variables did not indicate the dissemination. CONCLUSIONS: The expression of CD133 can be an efficient biomarker to predict intracranial dissemination in spinal cord astrocytoma. Recognition of high CD133 expression in surgical specimens and early detection of intracranial dissemination is important for the clinical management of spinal cord astrocytoma.

AB - BACKGROUND: Spondylometaphyseal dysplasia (SMD) is a rare disease characterized by vertebral and metaphyseal abnormalities. The treatment of SMD spinal deformities remains a challenge for spinal surgeons. The purpose of this study is to demonstrate the feasibility and effectiveness of vertebral column resection of SMD by thoracolumbar kyphosis and scoliosis. CASE DESCRIPTION: A 23-year-old man with SMD was referred to us with multivertebral anomalies and scoliosis, and a rigid curved thoracolumbar kyphosis in T11-12. The patient had fixed thoracolumbar kyphosis and scoliosis with neurologic symptoms. The morphology of vertebra was measured and calculated based on radiologic data. A 3-dimensional printing was made to help the spinal orthopedics. The anterior fusion was made with cages reconstruction and posterolateral fusion with screw fixation. CONCLUSIONS: The spinal axes were corrected with obvious and satisfying realignment effects. The neurologic symptoms disappeared after surgery. The 1 year follow-up period was uneventful. Surgical treatment for SMD multiaxial spine malformation is feasible. Posterior column resection with segmental pedicle screw fixation and complementary fusion provides obvious curative effects for adult patients with neurologic complications. PMID- 29180079 TI - Adult Pilocytic Astrocytoma: An Institutional Series and Systematic Literature Review for Extent of Resection and Recurrence. AB - INTRODUCTION: Pilocytic astrocytoma is a classically benign tumor that most often affects pediatric patients. Rarely, it occurs during adulthood. We present a case series and systematic literature review of adult pilocytic astrocytoma (APA) to examine the clinical presentation, extent of resection, and recurrence rate associated with this tumor in this population. MATERIALS AND METHODS: Our institutional records were retrospectively reviewed for cases of pilocytic astrocytoma in adults. A PubMed search identified English-language studies of pathology-proven APA. A meta-analysis was performed to determine the relationship between extent of tumor resection and recurrence. RESULTS: Forty-six patients with APA were diagnosed at our institution (mean age 33.6 +/- 13.3; 24 [52%] female). Twenty-four patients (52%) underwent gross total resection, 11 (24%) subtotal resection, 4 (9%) near total resection, 4 (9%) observation after biopsy, and 3 (6%) radiotherapy alone. Tumors recurred or progressed in 6 (13%) patients, of whom 4 were treated by STR and 2 were treated by radiotherapy alone. Thirty nine (95%) patients were still alive at last follow-up. A systematic literature review identified 415 patients with APA in 38 studies. Including our case series, 7 studies reported extent of resection, follow-up, and recurrence. Of 254 patients with a weighted mean follow-up of 77.7 +/- 49.6 (31-250) months, 129 (51%) were treated with gross total resection, and 125 (49%) underwent subtotal resection. Tumor recurred in 79 (31%) patients, 22 (27%) after gross total resection and 57 (73%) after subtotal resection (P < 0.001). CONCLUSIONS: Pilocytic astrocytoma rarely presents during adulthood. Overall, prognosis is favorable and survival rates are high. APA recurrence is more likely after STR, and the goal of surgery should always be GTR when feasible. PMID- 29180080 TI - Long-Term Outcome After Carotid Endarterectomy in Patients with Ischemic Heart Disease. AB - BACKGROUND: The long-term outcome after carotid endarterectomy (CEA) is determined by many confounding factors. Ischemic heart disease (IHD) is linked to atherosclerotic stroke, and it is an important cause of death during the perioperative and follow-up periods after CEA. We aimed to investigate mortality and long-term major adverse cardiovascular events (MACEs) in patients with IHD compared with patients who do not have IHD. METHODS: We consecutively enrolled 229 patients who underwent CEA procedures from 2000 to 2011. Of these patients, 45 had known or probable IHD defined by history or medical record of myocardial infarction, stable/unstable angina, previous coronary revascularization such as percutaneous coronary intervention or coronary artery bypass graft, or positive stress test. Long-term outcome was identified by using death certificates from the Korean National Statistical Office and telephone interviews by June 2013. We investigated predictors of early (<=30 days) and long-term mortality and MACEs (stroke, myocardial infarction, and death). RESULTS: Mean follow-up period was 49 months. Cox proportional analysis adjusted for potent predictors revealed symptomatic stenosis (hazard ratio, 1.72; 95% confidence interval, 1.02-2.88; P = 0.042) and presence of IHD (hazard ratio, 1.93; 95% confidence interval, 1.09 3.42; P = 0.025) as significant predictors of long-term MACEs. Kaplan-Meier analysis showed a significantly lower rate of survival (P = 0.030) and MACE-free survival (P = 0.003) in the IHD group. CONCLUSIONS: In this study, a poor long term outcome was observed in patients with IHD and symptomatic stenosis but not in patients with conventional high-risk factors for surgery. Therefore, appropriate evaluation and treatment of IHD before and after CEA might be helpful for better outcome. PMID- 29180081 TI - The Patient Size Setting: A Novel Dose Reduction Strategy in Cerebral Endovascular Neurosurgery Using Biplane Fluoroscopy. AB - BACKGROUND: In some fluoroscopy machines, the dose-rate output of the fluoroscope is tied to a selectable patient size. Although patient size may play a significant role in visceral or cardiac procedures, head morphology is less variable, and high dose outputs may not be necessary even in very obese patients. We hypothesized that very small patient size setting can be used to reduce dose for cerebral angiography without compromising image quality. METHODS: Patients who underwent endovascular neurosurgical procedures during the 2015-2016 academic year were identified, and estimated procedural air kerma (AK) was tabulated retrospectively. Technologists were instructed to begin using the very small patient size setting for all procedures performed using our Philips Allura Xper FD20 biplane fluoroscopy system beginning in March 2016. No changes were made in a second procedure room using a Toshiba Infinix system. Student t tests and logistic regression models were used to compare radiation exposure before and after March 1, 2016, for both machines. RESULTS: For diagnostic cerebral angiograms performed on the Philips system (n = 302), AK was reduced by approximately 17% (1277 vs. 1061 mGy; P = 0.0006.) Changes in table height, total fluoroscopy time, patient weight, and body mass index did not contribute to this difference. No significant change was seen in total AK using the Toshiba system (n = 237). Blinded review by a neuroradiologist did not demonstrate any change in image quality. CONCLUSIONS: Using the very small patient size reduces fluoroscopy dose by 17% for cerebral angiography without impacting image quality. PMID- 29180082 TI - Quantitative Volumetric Analysis Following Magnetic Resonance-Guided Laser Interstitial Thermal Ablation of Cerebellar Metastases. AB - BACKGROUND: Treating recurrent posterior fossa metastases after previous radiation therapy and surgical resection remains challenging. Magnetic resonance laser-induced thermal therapy (MR-LITT) is a promising treatment for recurrent lesions, but data on safety, efficacy, and postablation volume change in the posterior fossa are lacking. METHODS: All patients with recurrent posterior fossa metastatic lesions treated with MR-LITT by the senior neurosurgeon were included in the study. Preoperative and postoperative follow-up magnetic resonance imaging (MRI) studies were used to measure lesional and perilesional edema volume. These measurements were compared to calculate percent ablation volume. All patients' clinical examinations were followed closely. RESULTS: Four patients with recurrent cerebellar metastases were treated with MR-LITT. The average percent lesion ablated was 97.1% (range, 88.2%-100%). The average preoperative lesion volume was 3.3 cm3 (range, 1.1-7.2 cm3), and the average final postoperative volume was 3.8 cm3 (range, 0.5-7.6 cm3). Lesion volume increased to maximum volume on postoperative day 1, with an average increase of 486.9%. The extrapolated average time for the lesion to shrink to below the initial size was 294.5 days. There was a trend toward a decrease in average edema volume from the preoperative MRI of 17.8 cm3 to final postoperative follow-up MRI of 3.4 cm3 (P = 0.0952). No postoperative hydrocephalus or complications occurred. CONCLUSIONS: This pilot study shows that LITT appears to be a safe and promising treatment for recurrent posterior fossa metastatic lesions up to 7.2 cm3. Further randomized controlled studies are warranted to further characterize the long-term efficacy of this therapy. PMID- 29180083 TI - Rupture Resemblance Models May Correlate to Growth Rates of Intracranial Aneurysms: Preliminary Results. AB - BACKGROUND: Treatment of intracranial aneurysms (IAs) is largely guided by IA size and growth. Preliminary investigations have found a relationship between clinical factors and growth; yet, the relationship between morphologic and hemodynamic risk prediction models in IA growth is unknown. METHODS: We analyzed serial images of 5 growing and 6 stable IAs. Rupture resemblance scores (RRSs) were calculated from three-dimensional segmented images and computational fluid dynamics simulations. The morphologic (RRSM), hemodynamic (RRSH), and combination (RRSC) scores leveraged IA size ratio, wall shear stress, and oscillatory shear index. Comparisons of RRS and morphologic and hemodynamic characteristics were made between growing and stable IAs at the baseline time point and between the baseline and follow-up time points of the growing IAs. In addition, we investigated the correlation of growth rate and RRS and the hemodynamics of growing and stable regions were compared. RESULTS: Our results indicate that there is no statistical difference in IAs at the baseline time point; however, growing IAs tend to have a higher aspect ratio (P = 0.066), undulation index (P = 0.086), and RRSC (P = 0.86). In addition, we found a significant correlation between growth rate and baseline RRS of all 3 models (RRSM, r = 0.874, P < 0.001; RRSH, r = 0.727, P = 0.011; RRSC, r = 0.815, P = 0.002). We also found that growing IAs significantly increased in aspect ratio (P = 0.034), size ratio (P = 0.034), and RRSM (P = 0.034). Our results show that stable and growing regions had statistically different wall shear stress and oscillatory shear index. CONCLUSIONS: Based on this preliminary study, we conjecture that aneurysms that resemble ruptured IAs may grow faster. PMID- 29180084 TI - Cerebellar Mutism Syndrome and Other Complications After Surgery in the Posterior Fossa in Adults: A Prospective Study. AB - BACKGROUND: Cerebellar mutism syndrome (CMS) is rarely described in adults; however, data on self-assessed linguistic complications after posterior fossa surgery do not exist. METHODS: Through a prospective single-center study, data on 59 tumor operations in the posterior fossa were collected preoperatively as well as 1 week and 1 month postoperatively. Data on self-assessed problems in 5 CMS related domains, CMS scores, and neurology as well as surgical procedure and complications were obtained. RESULTS: Data on CMS-related complications were obtained on 56 of the 59 operations. None was found to have CMS according to the CMS score. Within each of the 5 domains, at least 9 operations (16%) were followed by development or worsening of self-assessed CMS-related complications. Self-assessed complications were found to be most frequent after primary tumor surgeries, although they were significant only for speech and motor complications (P value = 0.01 and 0.02). Speech and language complications occurred more frequently in midline tumors compared with lateral tumors (40% vs. 7%; P = 0.004). Surgical complications were similar to other studies. CONCLUSIONS: We propose that speech and language problems in adults undergoing surgery in the posterior fossa occur more frequently than previously assumed. Some of the self assessed complications might reflect components of the cerebellar cognitive affective syndrome. Our findings are consistent with the fact that midline location of the tumor is one of the few known risk factors for CMS in children. Thus, the cerebellar midline seems to be a vulnerable region for speech and language complications also in adults. PMID- 29180085 TI - Transvenous Embolization of Ethmoidal Dural Arteriovenous Fistulas: Case Series and Review of the Literature. AB - BACKGROUND: Ethmoidal dural arteriovenous fistulas (DAVFs) are rare and aggressive lesions, usually treated by microsurgical disconnection of the fistula. Transarterial embolization rarely is performed because of the risk of retinal ischemia. Transvenous embolization has been reported as an alternative approach. We describe our experience in transvenous embolization of ethmoidal DAVFs and review the literature focusing on technical and safety aspects of the procedure. METHODS: We retrospectively identified 4 patients with ethmoidal DAVFs treated by transvenous embolization in a single center. Clinical data and angiographic images were reviewed. We reviewed the literature after PubMed searching for articles describing patients treated by a transvenous approach. RESULTS: One patient was treated by transvenous coiling and 3 patients by retrograde Onyx injection through a detachable-tip microcatheter. Three fistulas drained in an ascending cortical frontal vein and one drained posteriorly in the olfactory vein. In all patients the fistula was occluded, in one case an asymptomatic hemorrhage occurred. In the literature 12 further cases of transvenous embolization of ethmoidal DAVFs have been reported. CONCLUSIONS: Transvenous embolization is an effective approach for the treatment of ethmoidal DAVFs in properly selected patients. Onyx injection through detachable-tip microcatheters increases the feasibility of the intervention. PMID- 29180086 TI - History, Current Situation, and Future Development of Endoscopic Neurosurgery in China. AB - OBJECTIVE: During the past few decades, Chinese endoscopic neurosurgery has rapidly developed in synchrony with the rest of the world. The aim of this article is to review the development of Chinese endoscopic neurosurgery, including its birth, growth, current situation, and prospects. METHODS: The history of Chinese endoscopic neurosurgery development can be divided into 3 stages: cognition and initial stage (1964-1995), exploration and maturity stage (1995-2006), and rapid development and promotion stage (2006-present). RESULTS: In the first stage, we mainly began to become aware of endoscopic neurosurgery from the translation and review of literature. In the mid to late 1990s, Chinese neurosurgery pioneers began using neuroendoscopic techniques. In the following decade, many leading neurosurgeons made persistent efforts to push the development of Chinese endoscopic neurosurgery forward, focusing on advocating for and promoting and popularizing neuroendoscopic technology. In the rapid development and promotion stage, many representative national and regional neurosurgical centers became skilled and efficient in the application of neuroendoscopic technology and became new advocates of the technology. The number of cases, level of technology, and treatment effectiveness are gradually nearing international standards. However, future development requires promotion of balanced development to decrease regional disparities, further strengthen international exchanges, follow the latest developments, and constantly innovate for continuous improvement. CONCLUSIONS: Following the dramatic efforts of several pioneers, development of Chinese endoscopic neurosurgery has been considerable, and it has become an important component of neurosurgery worldwide. PMID- 29180087 TI - Changes in Blood Flow Velocity of the Middle Cerebral Artery After Carotid Endarterectomy: Daily Assessment with Transcranial Color-Coded Sonography. AB - BACKGROUND: Hyperperfusion syndrome (HPS) is a well-known complication of carotid endarterectomy (CEA) warranting repeatable inexpensive monitoring. Transcranial color-coded sonography (TCCS) may provide a potential modality for such monitoring, but little is known about TCCS trends after CEA. METHODS: Between January 2016 and February 2017, we prospectively included patients with CEA at our institute in this study. TCCS was performed preoperatively and repeated daily from the operation day until postoperative day (POD) 7. Daily trends in mean flow velocity (MFV) at the M1 portion of the middle cerebral artery were compared between patients with and without HPS. RESULTS: Among 35 patients with CEA, daily TCCS monitoring was performed in 18 patients (mean age +/- SD, 72 +/- 7 years; male/female, 17:1). Among these 18 patients, 3 had probable HPS. On POD 0, MFV of the 18 patients showed a 32% increase from the initial preoperative value (from 52.5 to 69.4 cm/s, P = 0.0013). This increased MFV lasted for several days and recovered gradually by POD 7. Patients with probable HPS demonstrated a trend to higher MFV than those without; however, the difference was below the significance level. CONCLUSIONS: We used daily TCCS after CEA to depict cerebral blood flow changes after CEA in our cohort. This technique may be useful both for the detection and prevention of HPS. PMID- 29180088 TI - Simple New Screw Insertion Technique without Extraction for Broken Pedicle Screws. AB - OBJECTIVE: Spinal transpedicular screw fixation is widely performed. Broken pedicle screw rates range from 3%-7.1%. Several techniques have been described for extraction of broken pedicle screws. However, most of these techniques require special instruments. We describe a simple, modified technique for management of broken pedicle screws without extraction. No special instruments or drilling in an adjacent pedicle are required. METHODS: We used a high-speed air drill with a round burr. With C-arm fluoroscopy guidance, the distal fragment of a broken pedicle screw was palpated using free-hand technique through the screw entry hole. A high-speed air drill with a round burr (not a diamond burr) was inserted through the hole. Drilling began slowly and continued until enough space was obtained for new screw insertion. Using this space, we performed new pedicle screw fixation medially alongside the distal fragment of the broken pedicle screw. We performed the insertion with a previously used entry hole and pathway in the pedicle. The same size pedicle screw was used. RESULTS: Three patients were treated with this modified technique. New screw insertion was successful in all cases after partial drilling of the distal broken pedicle screw fragment. There were no complications, such as screw loosening, dural tears, or root injury. CONCLUSION: We describe a simple, modified technique for management of broken pedicle screws without extraction. This technique is recommended in patients who require insertion of a new screw. PMID- 29180089 TI - The pCONus2 Neck-Bridging Device: Early Clinical Experience and Immediate Angiographic Results. AB - BACKGROUND: Treating wide-necked aneurysms is challenging for the interventional neuroradiologist. Recently, numerous devices dedicated to the treatment of these aneurysms have become available. We report our early experience using the pCONus2 device and present the technical success rate, clinical outcomes, and immediate angiographic occlusion rates. METHODS: We performed a retrospective review of prospectively collected data to identify patients treated with the pCONus2 device between February 2015 and February 2017. RESULTS: We identified 12 patients (10 females) treated with the pCONus2 device. The average patient age was 56.6 +/- 15.8 years (range, 13-71 years). The average aneurysm dome width was 8.83 +/- 5.3 mm (range, 3.8-20 mm), the average dome height was 7.23 +/- 4.06 mm (range, 3.36 15 mm), and the average neck width was 5.88 +/- 2.92 mm (range, 2.77-11 mm). The angulation of the aneurysm to the parent vessel varied between 0 and 78 degrees (mean, 32.2 degrees ). Ten aneurysms were located in the anterior circulation, and 2 were in the posterior circulation. Immediate posttreatment angiography showed 11 aneurysms with modified Raymond-Roy classification (mRRC) grade I occlusion and 1 aneurysm with mRRC grade II occlusion. There were no deaths or hemorrhagic complications. Three patients developed small thrombi during treatment, all of whom were successfully treated with glycoprotein IIb/IIIa antagonists. Early angiographic follow-up data for 6 patients showed adequate aneurysm occlusion in 5 patients and aneurysm recanalization in 1 patient. CONCLUSIONS: The early results on the use of the pCONus2 device suggest that it can be useful for treating wide-necked aneurysms; however, larger studies with longer-term follow-up data are needed. PMID- 29180090 TI - Neurologic Deterioration in Patients with Moyamoya Disease during Pregnancy, Delivery, and Puerperium. AB - BACKGROUND: We reviewed our clinical experience of patients with moyamoya disease (MMD) who gave birth and assessed characteristics of those experiencing neurologic deterioration. METHODS: The patients were classified into patients diagnosed with MMD during pregnancy and puerperium (group 1) and those diagnosed before pregnancy (group 2). We retrospectively reviewed patient characteristics, MMD treatment, neurologic symptoms before and during pregnancy and/after puerperium, obstetrical history, and delivery type in groups 1 and 2. RESULTS: Group 1 included 2 patients with deterioration of pre-existing transient ischemic attacks (TIAs) and acute cerebral infarction and 1 patient with seizures and newly developed TIAs during pregnancy and/or puerperium. Group 2 included 20 patients with 23 pregnancies. In group 2, 4 patients had deterioration of TIAs during pregnancy and puerperium. There were significant differences between the cases without neurologic deterioration and with deterioration in group 2 (TIAs >=10 before pregnancy, 0% vs. 75%, P = 0.002; severely reduced regional cerebrovascular reserve on single-photon emission computed tomography, 10.5% vs. 100%, P = 0.002; and surgical revascularization before pregnancy, 75% vs. 15.8%, P = 0.04). In groups 1 and 2, 6 of the 7 cases in which TIAs occurred or worsened during pregnancy or puerperium recovered to prepregnancy TIA levels after puerperium. CONCLUSIONS: Patients with severely reduced regional cerebrovascular reserve on single-photon emission computed tomography and frequent TIAs before pregnancy may experience neurologic deterioration during pregnancy, delivery, and puerperium. Surgical revascularization before pregnancy may decrease neurologic deterioration during these periods. PMID- 29180091 TI - Prevalence of Surgically Untreated Face, Head, and Neck Conditions in Uganda: A Cross-Sectional Nationwide Household Survey. AB - BACKGROUND: The Surgeons OverSeas Assessment of Surgical Need tool (SOSAS) was created to evaluate the burden of surgically treatable conditions in low- and middle-income countries. The goal of our study is to describe the face, head, and neck (FHN) conditions that need surgical care in Uganda, along with barriers to that care and disability from these conditions. METHODS: A 2-stage cluster randomized SOSAS survey was administered in a cross-sectional manner between August and September 2014. Participants included randomly selected persons in 105 enumeration areas in 74 districts throughout Uganda with 24 households in each cluster. The SOSAS survey collected demographic and clinical data on all respondents. Univariate and multivariate logistic models evaluated associations of demographic characteristics and clinical characteristics of the FHN conditions and outcomes of whether health care was sought or surgical care was received. RESULTS: Of the 4428 respondents, 331 (7.8%) reported having FHN conditions. The most common types of conditions were injury-related wounds. Of those who reported an FHN condition, 36% reported receiving no surgical care whereas 82.5% reported seeking health care. In the multivariate model, literacy and type of condition were significant predictors of seeking health care whereas village type, literacy, and type of condition remained significant predictors of receiving surgical care. CONCLUSIONS: Many individuals in Uganda are not receiving surgical care and barriers include costs, rural residency, and literacy. Our study highlights the need for targeted interventions in various parts of Uganda to increase human resources for surgery and expand surgical capacity. PMID- 29180092 TI - Future considerations for clinical dermatology in the setting of 21st century American policy reform: The Relative Value Scale Update Committee. AB - The American Medical Association-Specialty Society Relative Value Scale Update Committee, also known as the RUC, plays a critical role in assessing the relative value of physician services and procedures. This committee provides access for all physicians, including dermatologists, to the reimbursement process. Since the introduction of the Resource-Based Relative Value Scale by Medicare, the RUC has done important work to evaluate and refine reimbursement for physician services. The RUC recommendations have also led the Current Procedural Terminology (CPT) Editorial Panel to develop additional reimbursement codes as new procedures and services are developed. In this article (from the series Future Considerations for Clinical Dermatology in the Setting of 21st Century American Policy Reform), we will review the RUC, including its history and membership, the RUC update process, and a brief discussion of a few issues of particular importance to dermatologists. PMID- 29180093 TI - Estimating the cost of skin cancer detection by dermatology providers in a large health care system. AB - BACKGROUND: Data on the cost and efficiency of skin cancer detection through total body skin examination are scarce. OBJECTIVE: To determine the number needed to screen (NNS) and biopsy (NNB) and cost per skin cancer diagnosed in a large dermatology practice in patients undergoing total body skin examination. METHODS: This is a retrospective observational study. RESULTS: During 2011-2015, a total of 20,270 patients underwent 33,647 visits for total body skin examination; 9956 lesion biopsies were performed yielding 2763 skin cancers, including 155 melanomas. The NNS to detect 1 skin cancer was 12.2 (95% confidence interval [CI] 11.7-12.6) and 1 melanoma was 215 (95% CI 185-252). The NNB to detect 1 skin cancer was 3.0 (95% CI 2.9-3.1) and 1 melanoma was 27.8 (95% CI 23.3-33.3). In a multivariable model for NNS, age and personal history of melanoma were significant factors. Age switched from a protective factor to a risk factor at 51 years of age. The estimated cost per melanoma detected was $32,594 (95% CI $27,326-$37,475). LIMITATIONS: Data are from a single health care system and based on physician coding. CONCLUSION: Melanoma detection through total body skin examination is most efficient in patients >=50 years of age and those with a personal history of melanoma. Our findings will be helpful in modeling the cost effectiveness of melanoma screening by dermatologists. PMID- 29180094 TI - Validation study of the Vitiligo Extent Score-plus.

PMID- 29180098 TI - Spontaneous painful disease in companion animals can facilitate the development of chronic pain therapies for humans. AB - OBJECTIVE: To outline the role that spontaneous osteoarthritis (OA) in companion animals can play in translational research and therapeutic pharmacological development. OUTLINE: Narrative review summarizing the opportunities and limitations of naturally occurring, spontaneous OA as models of human OA pain, with a focus on companion animal pets. The background leading to considering inserting spontaneous disease models in the translational paradigm is provided. The utility of this model is discussed in terms of outcome measures that have been validated as being related to pain, and in terms of the potential for target discovery is outlined. The limitations to using companion animal pets as models of human disease are discussed. CONCLUSIONS: Although many steps along the translational drug development pathway have been identified as needing improvement, spontaneous painful OA in companion animals offers translational potential. Such 'models' may better reflect the complex genetic, environmental, temporal and physiological influences present in humans and current data suggests the predictive validity of the models are good. The opportunity for target discovery exists but is, as yet, unproven. PMID- 29180096 TI - Differentiating Merkel cell carcinoma of lymph nodes without a detectable primary skin tumor from other metastatic neuroendocrine carcinomas: The ELECTHIP criteria. AB - BACKGROUND: Merkel cell carcinoma (MCC) can present as a cutaneous tumor or a lymph node metastasis without a primary tumor. MCC presenting without a primary tumor (MCCWOPT) can be misinterpreted on histologic examination as lymph node metastasis (LNM) from another neuroendocrine carcinoma (LNMNEC). However, this distinction is crucial for therapeutic management. OBJECTIVE: To determine the discriminative criteria for the differential diagnosis of MCCWOPT, LNM from cutaneous MCC, and LNMNECs. METHODS: Clinical, morphologic, and immunohistochemical data (expression of cytokeratins AE1, AE3, 7, 19, and 20; chromogranin A, synaptophysin, thyroid transcription factor-1 [TTF-1]), as well as the presence of Merkel cell polyomavirus (by immunohistochemistry and PCR) were compared in patients with MCCWOPT (n = 17), LNM from a cutaneous MCC (n = 11), and LNMNEC (n = 20; 8 lung, 7 thyroid, 3 digestive tract, 2 other). RESULTS: MCC (including MCCWOPT and LNM from a cutaneous MCC) differed from LNMNEC by 7 discriminative criteria: 1) elderly age, 2) location of the tumor, 3) extent of the disease, 4) cytokeratin expression, 5) TTF-1 expression, 6) histologic type, and 7) Merkel cell polyomavirus detection, summarized under the acronym ELECTHIP. All MCC patients had >=5 of the ELECTHIP criteria, whereas all patients with LNMNEC (except 1) had <3 criteria. LIMITATIONS: The discriminant ability of the ELECTHIP criteria should be validated in a second independent set. CONCLUSION: MCCWOPT can be distinguished from other LNMNEC by the ELECTHIP criteria. PMID- 29180099 TI - Comparison of fat suppression capability for chest MR imaging with Dixon, SPAIR and STIR techniques at 3 Tesla MR system. AB - PURPOSE: To directly compare fat suppression efficacy of Dixon, spectral attenuated inversion recovery (SPAIR) and short tau inversion recovery (STIR) techniques for a 3T MR system. MATERIALS AND METHODS: Nineteen consecutive patients (11 men, 8 women; mean age 67.9years) underwent chest MR imaging. Contrast-noise ratio (CNR) between muscle and fat (CNRFat) was calculated by ROI measurement. Then, two radiologists used a five-point scale for visual assessment of image quality, fat suppression capability and lesion detection. Next, the quantitative calculations obtained with all three techniques were compared by means of Tukey's honest significant difference (HSD) test. Inter-observer agreements were assessed by kappa statistics and chi2 test. Fisher's least significant difference (LSD) test was used for comparison among all scores. RESULTS: CNRFat of SPAIR were significantly higher than those of Dixon and STIR (p<0.001). Inter-observer agreements were assessed as significantly moderate, substantial or almost perfect (0.51= 0.48). TPD correlated with intensity and duration of pain (Pearson's r = 0.48, P < 0.05; Pearson's r = 0.77, P < 0.01). There was no sig difference between the two neck pain groups for any tactile acuity measure (TPD: P = 0.054; Graphesthesia; P = 0.67; Point to Point: P = 0.77), however, low power limited confidence in this comparison. CONCLUSION: People with chronic neck pain demonstrated tactile acuity deficits in painful and non-painful regions when measured using the TPD test, with the magnitude of deficits appearing greatest at the neck. The study also revealed a positive relationship between TPD and pain intensity/duration, further supporting the main study finding. PMID- 29180112 TI - MRI evaluation of the effects of extension exercises on the disc fluid content and location of the centroid of the fluid distribution. AB - BACKGROUND: McKenzie prone press-up exercises have been hypothesised to reduce intradiscal pressure, allowing fluid to be reabsorbed into the disc, which could improve the internal stability and local chemical milieu of the disc, potentially reducing symptoms. OBJECTIVE: To investigate the immediate effects of prone press up exercises on lumbar disc fluid content and movement. DESIGN: Quantification of MRI changes before and after a single exercise session. METHODS: The mid-sagittal T2-weighted MR images of 22 volunteers with low back pain were obtained before and immediately after performing press-up exercises. The whole disc and nucleus regions of the L4-5 and L5-S1 discs were then segmented, and their mean signal intensity (MSI) and signal intensity weighted centroid (SIWC) were computed to estimate disc fluid content and displacement. RESULTS: There were no significant differences between the MSI and the vertical position of the SIWC of the whole disc before and after extension at either disc level (effect size [ES]: -0.23 to 0.09). There was a significant anterior displacement (0.1 +/- 5.4 mm) of the location of the SIWC of the disc after extension exercise at L4-5 (ES: 0.22), but not at L5-S1 (ES: 0.00) or at either level for the nucleus region (ES: -0.06; 0.16). CONCLUSION: Little evidence was found supporting the hypothesis that press up exercises affect disc fluid content and distribution. Novel parameters reflecting fluid distribution detected similar or larger effects of the extension than MSI. If such exercises are effective in reducing symptoms, it is likely through other mechanisms than by changing fluid content or distribution. PMID- 29180113 TI - Two common mild analgesics have no effect on general endocrine mediated endpoints in zebrafish (Danio rerio). AB - Mild analgesics such as acetylsalicylic acid (ASA) and acetaminophen (APAP) exert their pain-relieving effect in humans by inhibition of prostaglandin synthesis. Prostaglandins play key roles in developmental and reproductive processes in vertebrates, and in recent years, it has been suggested that weak analgesics might also act as endocrine disrupters. In a set of experiments we investigated if ASA and APAP affect well-established endocrine endpoints in zebrafish (Danio rerio), which is a commonly used model organism in the investigation of endocrine disrupting chemicals. Zebrafish were exposed to APAP (0.22, 2.3, and 30mgL-1) or ASA (0.2, 0.5, 1.7, and 8.2mgL-1) from hatch to sexual maturity in a test design resembling the OECD Fish Sexual Development Test. No effects on sex ratio and vitellogenin levels were observed. Adult zebrafish were exposed to high concentrations (mgL-1) of ASA or APAP for eight or 14days. ASA reduced the levels of prostaglandin E2, but had no effect on the concentration of 11 ketotestosterone and vitellogenin. Overall, ASA decrease prostaglandin E2 concentrations, but well-established endpoints for endocrine disruption in zebrafish are generally not affected by aquatic exposure neither during development nor adulthood. According to the WHO/IPCS definition of an endocrine disrupter, the present results do not define APAP and ASA as endocrine disrupters.

This study describes the occurrence and nature of viruses associated with one population of wild Pterostylis sanguinea orchids, including their fungal symbionts, over two consecutive years. A generic sequencing approach, which combined dsRNA-enrichment from plant and mycelial tissues, random amplification and high throughput shotgun sequencing was used to identify novel viruses. The majority of the virus-like sequences represent partial genomes, and their identification is based solely on de novo assembly of sequencing data. In orchid leaf tissues we found three isolates of a novel totivirus and an unclassified virus; both resemble fungus-infecting viruses. Two isolates of Ceratobasidium sp that were isolated from orchid underground stems contained at least 20 viruses, 16 of which were previously described as alphapartitiviruses and betapartitiviruses. A novel hypovirus and a mitovirus were genetically distant from existing members of the genera and did not readily fit into recognised subgroups. PMID- 29180115 TI - Deletion of GIRK2 subunit containing GIRK channels of neurons expressing dopamine transporter decrease immobility time on forced swimming in mice. AB - We previously reported that non-narcotic antitussives possessing inhibitory actions on G protein-coupled inwardly rectifying potassium (GIRK) channels have antidepressant-like effects in the forced swimming test in normal and adrenocoticotropic hormone (ACTH) treated rats. Furthermore, the antidepressant like effects of the antitussives such as tipepidine were blocked by dopamine D1 receptor antagonist, and inhibitory actions on GIRK channels of dopamine neurons may be involved in the antidepressant-like effects of tipepidine. In this study, we generated GIRK2DATKO mice with Girk2/Kcnj6 conditional deletion and assessed depression-related behavior of the mice. The Cre/loxP system was used to selectively delete GIRK2 subunit containing GIRK channels in the neurons expressing dopamine transporter. First, deletion of GIRK2 subunits in the ventral tegmental area (VTA) neurons expressing dopamine transporters was confirmed by hisitochemically and electrophysiologically. In the mice, a significant decrease in the immobility time of forced swimming test was observed. Locomotor activity of the mice was not changed compared to that of GIRK2floxed mice, when tested in the open field. These results suggest that the antidepressant-like effect of antitussives such as tipepidine may be caused partly through the inhibitory actions on GIRK channels in the dopamine neurons. PMID- 29180116 TI - Association of different neural processes during different emotional perceptions of white noise and pure tone auditory stimuli. AB - Sound is a sensory stimulant ubiquitously found throughout our environment. Humans have evolved a system that effectively and automatically converts sound sensory inputs into emotions. Although different emotional responses to sounds with different frequency characteristics are empirically recognized, there is a paucity of studies addressing different emotional responses to these sounds and the underlying neural mechanisms. In this study, we examined effects of pure tone (PT) and white noise (WN) inputs at ordinary loudness levels on emotional responses. We found that WN stimuli produced more aversive responses than PT stimuli. This difference was endorsed by larger late posterior positivity (LPP). In a source localization study, we found increased neural activity in the parietal lobe prior to LPP. These findings show that WN stimuli produce aversive perceptions compared with PT stimuli, at typical loudness levels. In addition, different emotional responses were processed in a similar manner as visual stimulations, as reflected by increased LPP activation. Various emotional effects of WN and PT stimuli, at ordinary loudness levels, could expand our understanding of adverse effects of noise as well as favorable effects associated with music. PMID- 29180117 TI - The FOXO3-FOXM1 axis: A key cancer drug target and a modulator of cancer drug resistance. AB - The FOXO3 and FOXM1 forkhead box transcription factors, functioning downstream of the essential PI3K-Akt, Ras-ERK and JNK/p38MAPK signalling cascades, are crucial for cell proliferation, differentiation, cell survival, senescence, DNA damage repair and cell cycle control. The development of resistance to both conventional and newly emerged molecularly targeted therapies is a major challenge confronting current cancer treatment in the clinic. Intriguingly, the mechanisms of resistance to 'classical' cytotoxic chemotherapeutics and to molecularly targeted therapies are invariably linked to deregulated signalling through the FOXO3 and FOXM1 transcription factors. This is owing to the involvement of FOXO3 and FOXM1 in the regulation of genes linked to crucial drug action-related cellular processes, including stem cell renewal, DNA repair, cell survival, drug efflux, and deregulated mitosis. A better understanding of the mechanisms regulating the FOXO3-FOXM1 axis, as well as their downstream transcriptional targets and functions, may render these proteins reliable and early diagnostic/prognostic factors as well as crucial therapeutic targets for cancer treatment and importantly, for overcoming chemotherapeutic drug resistance. PMID- 29180118 TI - Role of bioactive lipofishins in prevention of inflammation and colon cancer. AB - Many clinical conditions exist in which it is desirable to stimulate or suppress the immune system, and many different drugs are able to do this. It is also well known that nutrition may affect human health and immune responses. Nutritional factors are crucial components of the diet and essential for normal growth and development of both vertebrate and invertebrate organisms. Many of these components have been shown to play different roles in the immune response and, under different circumstances, they can significantly modulate the immune system to create an effective response. Diet and its components are known to play an important factor in the process of inflammation and in turn on the health effects related to inflammation, such as cancer and cardiovascular diseases. Previous research so far has mainly looked at the effect of specific food stuffs or nutrients on inflammation and health outcomes. The aims of the present review was a) to underline the fact that diet as a whole plays an important role in modifying inflammation and health outcomes related to inflammation, aging, and colon cancer; b) to show the in vitro cytotoxic effect of LipoFishins (E Congerine 10423(r); AntiGanTM) obtained from the Atlantic Conger conger marine organism present on the Galician coast, against different human tumor cell lines; c) to show the in vivo effect of E-Congerine-10423(r) on colonic inflammation induced in mice by seven weeks' exposure to 2% of dextran sulfate sodium (DSS); and d) to show the effect of E-Congerine-10423(r) (AntiGanTM) on tumor markers (TMs) in healthy subjects and in patients with different types of cancer at the time of diagnosis. Preliminary data in a limited number of cases indicate that about 50% of the patients show a reduction in the levels of tumor markers (TM), and this response was much more evident in patients with cancer, when TM values are above normal range. Finally, all the above mentioned results suggest that diet has a major role in controlling inflammation and thereby plays an important role in the development or prevention of various chronic diseases, hence public health steps should be taken to modify the individual's whole diet and to promote the intake of specific natural compounds. PMID- 29180119 TI - Cyclopropane fatty acid synthesis affects cell shape and acid resistance in Leishmania mexicana. AB - Cyclopropane fatty acid synthase (CFAS) catalyzes the transfer of a methylene group from S-adenosyl methionine to an unsaturated fatty acid, generating a cyclopropane fatty acid (CFA). The gene encoding CFAS is present in many bacteria and several Leishmania spp. including Leishmania mexicana, Leishmania infantum and Leishmania braziliensis. In this study, we characterised the CFAS-null and overexpression mutants in L. mexicana, the causative agent for cutaneous leishmaniasis in Mexico and central America. Our data indicate that L. mexicana CFAS modifies the fatty acid chain of plasmenylethanolamine (PME), the dominant class of ethanolamine glycerophospholipids in Leishmania, generating CFA-PME. While the endogenous level of CFA-PME is extremely low in wild type L. mexicana, overexpression of CFAS results in a significant increase. CFAS-null mutants (cfas ) exhibit altered cell shape, increased sensitivity to acidic pH, and aberrant growth in serum-free media. In addition, the CFAS protein is preferentially expressed during the proliferative stage of L. mexicana and is required for the cell membrane targeting of lipophosphoglycan. Finally, the maturation and localization of CFAS protein are dependent upon the downstream sequence of the CFAS coding region. Without the downstream sequence, the mis-localised CFAS protein cannot fully rescue the defects of cfas-. Our data suggest that CFA modification of phospholipids can significantly affect the parasite's response to certain adverse conditions. These findings are distinct from the roles of CFAS in L. infantum, highlighting the functional divergence in lipid modification among Leishmania spp. PMID- 29180120 TI - Reply to the editor- Disseminated intravascular coagulation as a cause of shock related to device extraction.

AB - Identifying patients who are likely to achieve and maintain a therapeutic international normalized ratio when prescribed a vitamin K antagonist for stroke prevention in atrial fibrillation (AF) and venous thromboembolism (VTE) is challenging. The SAMe-TT2R2 score was developed on the basis of common clinical factors that can highlight patients who may be unable to achieve and maintain good anticoagulation control and for whom a "trial of warfarin" would be inadvisable. This review summarizes the main published prospective and retrospective studies that have validated the SAMe-TT2R2 score in patients with AF and VTE treated with a vitamin K antagonist and how the SAMe-TT2R2 score could aid clinical decision making; 19 studies were included. Taken together, validation studies suggest that the SAMe-TT2R2 score is able to predict good or poor anticoagulation control in patients with AF and VTE, although data on patients with VTE are limited (3 studies). The available evidence suggests that the SAMe-TT2R2 score may be a useful tool to aid clinical decision making for oral anticoagulants in patients with AF and VTE. PMID- 29180123 TI - Childhood- versus adult-onset ANCA-associated vasculitides: A nested, matched case-control study from the French Vasculitis Study Group Registry. AB - OBJECTIVE: To investigate differences between childhood-onset ANCA-associated vasculitides (cAAVs) and matched adult-onset controls (aAAVs). METHODS: cAAV clinical pictures at onset and outcomes were compared to a randomly selected sample of aAAV patients from the French Vasculitis Study Group Registry. Cases and controls were matched for AAV (granulomatosis with polyangiitis [GPA], microscopic polyangiitis [MPA] or eosinophilic granulomatosis with polyangiitis [EGPA]), sex and year of enrollment. Medications, disease activity and damage were prospectively recorded. Kaplan-Meier curves and the log-rank test were used to analyze case-vs.-control differences for predefined outcomes. RESULTS: Comparing 35 cAAVs (25 GPA, 4 MPA, 6 EGPA) to 151 aAAVs (106 GPA, 17 MPA, 28 EGPA), their respective median follow-up durations were 71 and 64months (P=0.49), and, at baseline, children had less frequent myalgias (P=0.005) and peripheral neuropathy (P<0.001) but were more frequently febrile (P<0.05). Rates of renal involvement were comparable (13 [37%] cAAVs vs. 73 [48%] aAAVs; P=0.31). Initial GPA-associated ischemic abdominal pain and nasal cartilage damage were more common in cAAVs than aAAVs (P<0.05). During follow-up, the cAAV relapse rate was higher (24.5 vs. 18.7 flares per 100 patient-years; P<0.05) and, at last visit, cases had accumulated more damage, mostly ear, nose & throat sequelae (P=0.001), associated with longer maintenance therapy (P=0.03), than aAAV controls. Four (11.4%) cAAV and 13 (8.6%) aAAV patients died (P=0.53). CONCLUSION: cAAVs are severe diseases, characterized by a higher relapse rate, more accrued damage and longer maintenance therapy than for aAAVs. PMID- 29180124 TI - NK cells in autoimmune diseases: Linking innate and adaptive immune responses. AB - The pathogenesis of autoimmunity remains to be fully elucidated, although the contribution of genetic and environmental factors is generally recognized. Despite autoimmune conditions are principally due to T and B lymphocytes, NK cells also appear to play a role in the promotion and/or maintenance of altered adaptive immune responses or in peripheral tolerance mechanisms. Although NK cells are components of the innate immune system, they shows characteristics of the adaptive immune system, such as the expansion of pathogen-specific cells, the generation of long-lasting "memory" cells able to persist upon cognate antigen encounter, and the possibility to induce an increased secondary recall response to re-challenge. Human NK cells are generally identified as CD56+CD3-, conversely CD56+CD3+ cells represent a mixed population of NK-like T (NK T) cells and antigen-experienced T cells showing the up-regulation of several NK cell markers. CD56dim constitute about 90% of NK cells in the peripheral blood, they are mature and involved in cytotoxicity responses; CD56bright instead are more immature, mostly involved in cytokine production, having only a limited role in cytolytic responses, keen to leave the blood vessels as the principal population observed in lymph nodes. NK cells have been identified also in non-lymphoid tissues since, in pathologic conditions, they can quickly reach the target organs. A cross-talk between NK with dendritic cells and T cells is established throughout different receptor-ligand bindings. Several studies support the correlation between NK cell number and/or functional alterations, such as a defective cytotoxic activity and several autoimmune conditions. Among the different autoimmune pathologies and even within the same disease, NK cell function is significantly different either promoting or even protecting against the onset of the autoimmune condition. In this Review, we discuss recent literature supporting the role played by NK cells, as a bridge between innate and adaptive immunity, in the onset of autoimmune diseases. PMID- 29180125 TI - Clinical and microbiological characteristics of the infections in patients treated with rituximab for autoimmune and/or malignant hematological disorders. AB - INTRODUCTION: Rituximab is commonly used for the treatment of hematological malignancies and autoimmune diseases. Despite a reputation for good tolerance, case-series and registries reported rituximab-related infections of variable severity including opportunistic infections. We aimed at describing the natural history of infectious events (IE) after treatment by rituximab providing clinical and microbiological features and outcome. PATIENTS AND METHODS: We retrospectively analyzed the medical records of patients treated with rituximab in an internal medicine department of a tertiary hospital between 2007 and 2015, and identified all IE after this therapy. Events' severity was assessed using the Common Terminological Criteria of Adverse Events (version 4.3) definitions. RESULTS: Among 101 patients treated with rituximab, we identified 228 IE in 74 (73.3%) of these patients (median follow-up 30.4months). Indication for rituximab was either autoimmune disease (AID) (52.5% of patients), or monoclonal hematological disease (MHD) (47.5%). Patients received an overall median number of 5 rituximab infusions [interquartile range: 4-8], representing a cumulative dose of 4340mg [2620-6160]. After last rituximab infusion, IE occurred after 3.1months [0.7-9.4]. Respectively, IE were severe in 28.1% of cases in patients treated for AID vs 58.0% in patients treated for MHD (p<0.001), due to opportunistic pathogens in 7.8% vs 11.0% (p=0.49) and fatal in 4.7% vs 13.0% (p=0.044). Factor associated with mortality were polymicrobial infection (p<0.001), monoclonal hematological disease (p=0.035), use of steroids over 10mg/d within the last two weeks (p=0.003), and rituximab cumulative dose (p<0.001). We identified a group of 10 patients (9.9%) showing life-threatening, polymicrobial, and opportunistic infections constituting a 'catastrophic infectious syndrome', which was lethal in 7 cases. CONCLUSION: IE after treatment by rituximab can be extremely severe, especially in patients immunocompromised by several other drugs. Further studies should focus on the group with life threatening polymicrobial infections. PMID- 29180126 TI - Belimumab in the treatment of systemic lupus erythematous: An evidence based review of its place in therapy. AB - INTRODUCTION: Systemic lupus erythematous is an autoimmune disease with diverse clinical features and has its development associated with a complexity of genetic, hormonal and environmental factors and the development of autoantibodies. Identification of new treatments is currently an area of intense investigation. Belimumab is the first biologic approved for the treatment of the disease inhibiting the excessive B cell activity observed in these patients and consequently reduction of autoantibodies. AIM: To review the current transition of the evidence available of its use in real life patients with persistent active disease while on conventional therapies. EVIDENCE: The results observed on the large series of patients (over 50 patients) followed for at least six months confirm the observations from phase 3 trials. In clinical practice close to two third of the patients remained on belimumab and one third discontinued mostly due to evaluation by the doctor or the patient or both of no detectable positive response. The presence of adverse events was considerably low and the subgroups with skin and joint manifestations appear to benefit the most. Daily steroid use is usually reduced to a significantly low when compared with the intake before introduction of the biologic Although not seen on trials in real life the addition of belimumab to the conventional therapy in lupus nephritis is being reported in several patients. Cost of the medication is still an issue that hampers its use. Further evidence of its use in certain specific groups is under investigation and its results should shed light on additional indications. PLACE IN THERAPY: Considering what is currently published on the evidence here reviewed in the use of belimumab in clinical practice it is our understanding that belimumab it will be gradually incorporated in the armamentarium of treatment not necessarily on refractory patients. We believe that with the upcoming of the subcutaneous route in the near future should also help in widen the use of the belimumab to be considered in first line combination set ups. PMID- 29180127 TI - Curcumin: A natural modulator of immune cells in systemic lupus erythematosus. AB - Curcumin is a polyphenol natural product isolated from turmeric, interacting with different cellular and molecular targets and, consequently, showing a wide range of pharmacological effects. Recent preclinical and clinical trials have revealed immunomodulatory properties of curcumin that arise from its effects on immune cells and mediators involved in the immune response, such as various T-lymphocyte subsets and dendritic cells, as well as different inflammatory cytokines. Systemic lupus erythematosus (SLE) is an inflammatory, chronic autoimmune mediated disease characterized by the presence of autoantibodies, deposition of immune complexes in various organs, recruitment of autoreactive and inflammatory T cells, and excessive levels of plasma proinflammatory cytokines. The function and numbers of dendritic cells and T cell subsets, such as T helper 1 (Th1), Th17, and regulatory T cells have been found to be significantly altered in SLE. In the present report, we reviewed the results of in vitro, experimental (pre clinical), and clinical studies pertaining to the modulatory effects that curcumin produces on the function and numbers of dendritic cells and T cell subsets, as well as relevant cytokines that participate in SLE.

AB - Epidermolysis bullosa (EB) is a rare genetic disease that causes mucocutaneous fragility. It comprises a clinically and genetically heterogeneous group of disorder characterized by spontaneous or contact/friction-induced blistering. EB is classified into 4 types-simplex, junctional, dystrophic, and Kindler syndrome and 30 subtypes. The disease is caused by defects in proteins implicated in dermal-epidermal adhesion. At least 19 genes have been characterized and more than 1000 mutations identified, thus rendering diagnosis complex. Molecular diagnosis of EB is the last stage of a laborious process that starts with a detailed clinical history compilation and careful procurement of a skin fresh biopsy that includes an area where the epidermis detaches from the dermis. The detachment area makes it possible to establish the cleavage plane by antigen mapping and, in the best scenario, to identify a single candidate gene to search for pathogenic mutations. The results of the molecular diagnosis enable the physician to provide appropriate genetic counseling (inheritance pattern, risk of recurrence, and options for prenatal and preimplantation diagnosis) and implement subsequent preventive programs, as well as to establish a reasonable clinical prognosis facilitating access to specific therapy and rehabilitation. Lastly, molecular diagnosis is essential for the participation of patients in clinical trials, a critical issue given the current incurable status of EB. The present guidelines aim to disseminate the procedure for diagnosing EB in our laboratory and thus avoid suboptimal or incomplete clinical diagnoses. The recommendations we provide are the result of more than 10 years' experience in the molecular diagnosis of EB in Spain. PMID- 29180130 TI - Factors associated with low levels of physical activity among elderly residents in a small urban area in the interior of the Brazilian Amazon. AB - The aim of the present study was to investigate levels of physical activity and risk factors for inactivity in older adults living in an urban area in the interior of the Amazonas state, Brazil. Data were collected between 2013 and 2015 from 274 individuals 60 years of age or older who resided in the interior of the Brazilian Amazon. Sociodemographic, general health, functional capacity and physical performance were associated with self-referred physical activity level. A multivariate analysis, after adjustment, showed that being a man, having a body mass index above 27kg/m2, never having lived in riverside communities and having less than three associated chronic diseases were independent risk factors for low levels of physical activity among elderly residing in the interior of the Brazilian Amazon. Few studies have been conducted about the characteristics that are singular to this population. Our results suggest that the physical activity level and, consequently, the aging process of the elderly is influenced by where they have resided throughout their lives. Additionally, the results showed particular risk factors associated with low physical activity level among older adults residing in the interior of the state of Amazonas. PMID- 29180131 TI - Impact of coexisting overactive bladder in Medicare patients with osteoporosis. AB - BACKGROUND: Osteoporosis and overactive bladder (OAB) are prevalent conditions in older adults and are independent risk factors for falls and fractures. A paucity of evidence exists examining the impact of coexisting OAB in patients with osteoporosis. OBJECTIVE: To examine the impact of OAB on healthcare resource utilization (HRU), clinical outcomes, and healthcare costs among older adult patients with osteoporosis. METHODS: This retrospective analysis compared patients with osteoporosis with and without OAB. Patients with an osteoporosis diagnosis, enrolled in a Medicare Advantage plan, and aged 65-89 inclusive were eligible. Incident OAB among patients with prevalent osteoporosis was identified. A comparison group of patients with osteoporosis but no evidence of OAB was propensity score matched on baseline characteristics. Fall and/or fracture outcomes, HRU and healthcare costs were evaluated during 12 months of follow-up. Bivariate comparisons of outcomes were conducted. Ordinary least squared regression was used to examine the relationship between OAB and total healthcare costs. RESULTS: After matching, 5,526 patients in each group were included. Patients with osteoporosis and OAB demonstrated greater all-cause HRU across all encounter types compared to patients without OAB (all P values<0.001). Patients with osteoporosis and OAB had a greater frequency of any fall/fracture (17.7% vs. 14.9%, P<0.001). Patients with osteoporosis and OAB had 35% greater all-cause total healthcare costs than patients without OAB (P<0.001). CONCLUSIONS: Patients with OAB and osteoporosis had significantly greater all-cause HRU and costs. Falls and fractures were significantly more common in patients with osteoporosis and OAB compared to patients with osteoporosis without OAB. PMID- 29180132 TI - The effect of intravitreal cholinergic drugs on motor control. AB - The retina bears embryological, neurochemical and functional similarities to the circadian and dopamine systems of the brain. Recent studies have shown that the intravitreal injection of minute quantities of L-dopa and of the melatonin receptor antagonist ML-23 have anti-Parkinsonian potential. Furthermore, it has been suggested that light therapy may be potentially useful in treating some aspects of Parkinson's disease (PD) and it is hypothesized that this treatment works via the circadian system. Given that little is known about the mechanism by which such treatments work the present study was designed to examine the role of the acetyl cholinergic system of the retina in gross bodily movement. While IVIT atropine was shown to improve movement in intact rats Cogentin treated rats showed impairment of motor function compared to control rats or to rats treated with any other cholinergic drug. Furthermore, a link between the phase of the light/dark cycle and the efficacy of these drugs in altering movement was demonstrated. These results show that anticholinergic systems in the retina can exert control over movement which has been solely attributed to the function of deep brain structures. PMID- 29180133 TI - Cognitive, neurohistological and mortality outcomes following the four-vessel occlusion/internal carotid artery model of chronic cerebral hypoperfusion: The impact of diabetes and aging. AB - Chronic cerebral hypoperfusion (CCH) may be involved in the etiology of aging related dementias, and several risk factors contribute to their development and/or aggravation. We previously reported on the development of the 4-VO/ICA model of CCH, and the impact of hypertension on the cognitive and histological outcomes of CCH. Here, we advanced those studies by investigating how 4-VO/ICA alone or in combination with diabetes affects survival, body weight and cognitive performance in both young and middle-aged rats. Subsequently, middle-aged rats were examined for the impact of diabetes on CCH-induced neurodegeneration, white matter damage, and glial cells response. Diabetes alone reduced body weight and increased mortality rate slightly in young rats; these effects were striking, however, in the older animals. After CCH alone, neither body weight nor mortality rate changed significantly in both age groups. However, when CCH was combined with diabetes, mortality rate increased significantly in both aged groups. Young rats were cognitively asymptomatic to CCH, but they became 'mildly' impaired after CCH combined with diabetes. In middle-aged rats, CCH severely impaired memory, which was significantly worsened by diabetes. Moreover, diabetes aggravated neurodegeneration in the hippocampus and white matter injury in the corpus callosum and it promoted glial activation in the hippocampus and white matter of CCH middle-aged rats. These data suggest that diabetes interacts synergistically with age and reduces the capacity of the brain to adequately respond to CCH and highlight the importance of associating risk factors in the preclinical investigation of age-related cerebrovascular diseases physiopathology and potential therapies. PMID- 29180134 TI - Learning and memory are impaired in the object recognition task during metestrus/diestrus and after sleep deprivation. AB - Females are an under-represented research model and the mechanisms through which sleep loss impairs cognition are not clear. Since levels of reproductive hormones and the estrous cycle are sensitive to sleep loss and necessary for learning and memory, we hypothesized that sleep deprivation impacts learning and memory in female mice by interfering with the estrous cycle. We used the object recognition task to assess learning and memory in female mice during separate phases of the estrous cycle and after sleep loss. Mice in metestrus/diestrus attended to sample objects less than mice in proestrus/estrus during object acquisition, the first phase of the object recognition task. Subsequently, during the recognition phase of the task, only mice in proestrus/estrus displayed a preference for the novel object. Sleep deprivation for 12h immediately before the object recognition task reduced time attending to sample objects and novel object preference for mice in proestrus/estrus, without changing length of the estrous cycle. These results show that sleep deprived mice in proestrus/estrus had learning deficits and memory impairments, like mice in metestrus/diestrus. Since sleep deprivation did not disrupt the estrous cycle, however, results did not support the hypothesis. Cognitive impairments due to acute sleep loss were not due to alterations to the estrous cycle. PMID- 29180135 TI - Alpha-Synuclein transgenic mice, h-alpha-SynL62, display alpha-Syn aggregation and a dopaminergic phenotype reminiscent of Parkinson's disease. AB - Alpha-Synuclein (alpha-Syn) accumulation is considered a major risk factor for the development of synucleinopathies such as Parkinson's disease (PD) and dementia with Lewy bodies. We have generated mice overexpressing full-length human alpha-Syn fused to a membrane-targeting signal sequence under the control of the mouse Thy1-promotor. Three separate lines (L56, L58 and L62) with similar gene expression levels, but considerably heightened protein accumulation in L58 and L62, were established. In L62, there was widespread labelling of alpha-Syn immunoreactivity in brain including spinal cord, basal forebrain, cortex and striatum. Interestingly, there was no detectable alpha-Syn expression in dopaminergic neurones of the substantia nigra, but strong human alpha-Syn reactivity in glutamatergic synapses. The human alpha-Syn accumulated during aging and formed PK-resistant, thioflavin-binding aggregates. Mice displayed early onset bradykinesia and age progressive motor deficits. Functional alterations within the striatum were confirmed: L62 showed normal basal dopamine levels, but impaired dopamine release (upon amphetamine challenge) in the dorsal striatum measured by in vivo brain dialysis at 9 months of age. This impairment was coincident with a reduced response to amphetamine in the activity test. L62 further displayed greater sensitivity to low doses of the dopamine receptor 1 (D1) agonist SKF81297 but reacted normally to the D2 agonist quinpirole in the open field. Since accumulation of alpha-Syn aggregates in neurones and synapses and alterations in the dopaminergic tone are characteristics of PD, phenotypes reported for L62 present a good opportunity to further our understanding of motor dysfunction in PD and Lewy body dementia. PMID- 29180136 TI - Obstacle circumvention and eye coordination during walking to least and most affected side in people with Parkinson's disease. AB - BACKGROUND: The mechanisms that contribute to gait asymmetry in people with Parkinson's disease (PD) are unclear, mainly during gait with greater environmental demand, such as when an obstacle is circumvented while walking. OBJECTIVE: The aim of this study was to investigate the effects of obstacle circumvention of the least and most affected side on motor and gaze behavior in people with PD under/without the effects of dopaminergic medication. METHODS: Fifteen people with PD and 15 matched-control individuals were instructed to walk along a pathway, at a self-selected velocity, and to circumvent an obstacle, avoiding contact with it. Each participant performed five trials for each side. Kinematic parameters, mediolateral and horizontal body clearance to the obstacle, strategy to circumvent the obstacle, and gaze behavior were calculated. Parameters were grouped according to the side that the obstacle was circumvented and compared by three-way ANOVAs. RESULTS: Both people with PD and the control group presented asymmetry to circumvent an obstacle during walking, however this was exacerbated in people with PD. Individuals with PD presented safe strategies (largest mediolateral and horizontal body clearance to the obstacle, "lead-out" strategy, and higher number and time of fixations on the obstacle) during obstacle circumvention for the least affected side compared to the most affected side. In addition, positive effects of dopaminergic medication on body clearance, spatial-temporal parameters, and gaze behavior were evidenced only when the obstacle was circumvented to the least affected side. CONCLUSIONS: The obstacle circumvention to the most affected side is risky for people with PD. PMID- 29180138 TI - Estimation of sex in a contemporary Saudi population based on sternal measurements using multidetector computed tomography. AB - Sex estimation is an essential step for identifying unknown individuals and usually depends on the presence of highly dimorphic bones, such as the pelvis and skull. Nevertheless, the body integrity can be compromised in certain circumstances, and these bones might be absent; therefore, the ability to use other bones for sex estimation is crucial. The aims of this study were to collect baseline data for sternal dimensions in Saudi adults, assess the existence of sexual dimorphism in the sternum, and generate population-specific equations to estimate sex using sternal dimensions. During 2014-2015, 200 thoracic/thoraco abdominal computed tomography (CT) images (100 men, 100 women) were anonymously collected from King Abdulaziz Medical City. Six measurements were obtained and two indices calculated after 3D reconstruction of the CT scans. Descriptive statistics were calculated, and sexual dimorphism was assessed using independent t-tests. Discriminant function equations were developed for these measurements. Except for the sternal index, men had significantly larger dimensions than women. Sexual dimorphism was highly significant (p<0.001). The best predictor was the combination of the manubrium and sternal body lengths (89.5%). In the stepwise analysis, the best predictors were the manubrium length, sternal body length, manubrium width, and corpus width at the first sternebra, with a cross-validated accuracy of 90.5%. Cross-validated accuracy for all measurements ranged between 62.5% and 90.5%. The findings of the study may have important anatomical, anthropological, and forensic applications.

We aimed to investigate whether the effects of ELS on working memory (WM) performance depend on the valence of the stimuli. METHODS: Between January and October 2015, we recruited (N=31) healthy subjects with (N=15) and without (N=16) ELS experiences. Participants performed a WM-task with emotional stimuli. RESULTS: Results show a trend towards decreased WM accuracy in subjects with ELS experiences (p=.06) with increased WM accuracy (p=.08) and an altered pattern of BOLD responses in the left posterior cingulate cortex (PCC)/precuneus (p<.001) and the rostral anterior cingulate cortex (rACC) (p<.01) in response to negative stimuli. LIMITATIONS: The small sample size and potential confounding factors should be considered when interpreting the results. CONCLUSION: Our data suggests that negative valence influences cognitive performance and brain activity in subjects with ELS experiences.

AB - To test the hypothesis that gastrin releasing peptide-29 (GRP-29) combined with glucagon like peptide-1 (7-36) (GLP-1 (7-36)) reduce body weight (BW) more than each of the peptides given individually, we infused the two peptides (0.5nmol/kg each) in the aorta of free feeding, diet-induced obese (DIO) male Sprague Dawley rats once daily for 25days and measured BW. We found that GRP-29 and GLP-1 reduce BW, GRP-29 reduced it more than GLP-1 and GRP-29+GLP-1 reduce BW more than each peptide given alone. This reduction was accompanied by decrease 24-hour food intake (normal rat chow), meal size (MS), duration of first meal and number of meals, and increase latency to the first meal, intermeal interval (IMI) and satiety ratio (IMI/MS, amount of food consumed per a unit of time). Furthermore, the peptides and their combination decreased 24-hour glucose levels. In conclusion, GRP-29+GLP-1 reduce BW more than each of the peptides given individually. PMID- 29180140 TI - Grit: An important characteristic in learners. AB - Grit, or the perseverance and passion for long-term goals, has been associated with successful pursuits in academics, competitions, and professions outside of pharmacy. The fortitude needed to withstand tremendous physical, mental, and emotional stressors may be better predicted by grit than other factors. In those who demonstrate grit, a combination of factors may reflect academic achievement. It appears that achievement results when talent and effort are combined, with particular attention being paid to effort, as it is a function of the direction, duration, and intensity of a person's actions toward a goal. It appears that grit may be a good discriminating factor when evaluating individuals in other professions. The objective of this short commentary is to provide an introduction to the non-pharmacy literature surrounding grit and to suggest its applications in pharmacy. PMID- 29180141 TI - Use of a health screening and education event to change student attitudes toward the elderly. AB - BACKGROUND: While many schools have incorporated geriatric pharmacy education into their curricula, questions remain as to how these experiences shape student perceptions of the geriatric population. The objective of this study was to assess student comfort levels and perceptions toward the geriatric patient population before and after participation in a single health screening and education event. METHODS: Student perceptions about the elderly (measured via the Geriatrics Attitude Survey) and comfort levels in caring for geriatric patients were assessed before and after an event. RESULTS: Twenty-two students completed pre-event and post-event surveys. Students were primarily female (73%), and half were completing their second year of pharmacy school (50%). Global student perceptions of geriatric patients positively changed from baseline following event participation (p = 0.023). Results reveal significant increases from baseline in student comfort levels with communicating, screening, and counseling elderly patients (p < 0.001, 0.01, and 0.001, respectively). CONCLUSION: The Geriatrics Attitude Survey is a useful tool in assessing the value of a geriatric experience. Participation in this geriatric experience caused a statistically significant positive change in global perception scores. Additionally, survey results indicate that interactions with geriatric patients at a single event increased student comfort in communication, screening, and counseling. PMID- 29180142 TI - The impact of proctored online exams on the educational experience. AB - PURPOSE: This study explored new ways to maintain academic integrity for large enrollment, completely online courses. We examined the use of ProctorU as our proctoring strategy with the objectives to identify any implementation challenges and understand the impact of using an online proctor on the student experience. METHODS: In fall 2013, students were surveyed after each exam. Based on these preliminary findings, ProctorU-related questions were included in the course evaluation administered in spring 2014. A mixed-methods analysis plan was used to examine the results, including quantitative analysis and qualitative analysis of open-ended survey questions. RESULTS: In the fall 2013 surveys, 88.95% of students reported being satisfied with their experience using ProctorU. Of those who were unsatisfied, following three emerging themes were identified: took too long to setup, technical difficulties, and personnel issues with proctors. In the spring 2014 course evaluation data, the majority of students rated the experience "good" (57.53%), but a large number of those same students also commented on issues they encountered. Over half of the students indicated that the use of ProctorU would influence their future decision to take another online course, either negatively or positively. CONCLUSIONS: The question of how to maintain academic integrity with online courses is still an ongoing question, but this project demonstrates that online proctoring does influence the educational experience in ways that must be considered when determining the risk and benefit balance of proctored and unproctored assessments. PMID- 29180143 TI - Development of a college-level assessment framework in line with international accreditation standards: A Middle Eastern perspective. AB - INTRODUCTION: Accreditation of international pharmacy programs by North American and European accrediting bodies is becoming increasingly popular. Practices regarding assessment and evaluation are especially highlighted in accreditation standards and many programs around the world do not currently have coordinated approaches to meet assessment expectations. This article describes the process of developing a comprehensive assessment framework at our institution and provides discussion regarding facilitators and barriers for those attempting to do the same. METHODS: A coordinator of Assessment and Accreditation was appointed by the Dean. This person subsequently formed an Assessment Committee consisting of faculty, student, and administrative support membership. This committee developed the assessment framework through a review of published and online literature, in addition to extraction of key assessment points from accreditation standards. These data were then categorized according to major domains informed by the literature review and subcategorized based on components to be assessed using consensus techniques. RESULTS: A comprehensive assessment framework was developed consisting of three domains (programmatic assessment, academics, and engagement/satisfaction). The components relating to programmatic assessment included vision/mission and accreditation standards; academics consisted of program learning outcomes, final cumulative assessment, and course and curriculum assessments; and engagement/satisfaction consisted of students, faculty/staff, and other stakeholders. CONCLUSION: An assessment framework guided by accreditation standards can coordinate assessment plans and support program quality. PMID- 29180144 TI - Predicting pharmacy students' intention to apply for a residency: A systematic theory of planned behavior approach. AB - OBJECTIVE: The current literature has identified many motivating factors and barriers influencing pharmacy students' decision to apply for residency training. Despite a growing need for residency trained pharmacists to advance the profession, it is not clear why only about one in four pharmacy students decide to pursue a residency, and which of these factors have the most influence on student decision-making. The study examines the factors associated with pharmacy students' intention to apply for a postgraduate residency using the theory of planned behavior (TPB) framework. METHODS: Second and third-year students from four Texas pharmacy schools were surveyed using an online questionnaire based on the TPB. Descriptive statistics and multiple linear regression analyses were utilized to assess the study objectives. RESULTS: A total of 251 completed responses were received. Attitude, subjective norms (SN), and perceived behavioral control (PBC) were significant predictors of intention to apply for a pharmacy residency (beta = 0.32, 0.58, and 0.36, respectively, p < 0.001). Attending ASHP's midyear meeting or other residency showcase was a significant predictor of intention (beta = 0.71, p = 0.006). Additional significant predictors of intention include believing a residency would increase confidence in practicing pharmacy (beta = 0.36, p < 0.001) and help achieve career goals (beta = 0.16, p < 0.02); the social influence of faculty members (beta = 0.10, p = 0.003) and family (beta = 0.08, p = 0.02); believing financial obligations (beta = 0.20, p = 0.006), feeling afraid of the competition and/or not matching (beta = 0.24, p < 0.001), needing to relocate (beta = 0.09, p = 0.04), and the lengthy application and/or interview process (beta = 0.12, p = 0.04) would make it more difficult to apply for a residency. CONCLUSIONS: The TPB model was useful in predicting pharmacy students' intention to apply for a residency, and all TPB constructs were significant predictors. Therefore, interventions that target students' attitude, SN, and PBC may be valuable to increase their intention, especially the specific beliefs identified to significantly predict intention. Future research into methods in which these motivating factors can be encouraged and perceived barriers can be addressed by pharmacy stakeholders will increase interest and participation in residency training. PMID- 29180145 TI - Design, analysis, and conclusions: Telling a consistent causal story. AB - Pharmacy educators are dedicated to providing the best education to student pharmacists and post-graduate trainees. This involves developing and evaluating new educational approaches or activities, as well as working to understand better other factors that may affect student and program outcomes. Although we may not realize it, the idea of causality, or the presence of a cause-and-effect relationship, is embedded in much of what we do when engaging in pharmacy educational scholarship. Saying that an educational intervention is effective at improving test scores implies that the intervention caused the increase. Perhaps more subtly, a cause-and-effect relationship is implied when identifying poor interviewing skills as a factor that reduces the likelihood that a student will obtain a pharmacy practice residency. The extent to which causal claims can be made depends on appropriate study design and analysis. Similarly, the language used to present these claims is related to study design and analysis. Unfortunately, study designs used when evaluating educational approaches do not always align with the language used to report the results. This review provides a brief overview of current thinking related to causal inference. The role of study design and analysis in causal inference is also discussed along with recommendations for study design and analysis to facilitate making appropriate causal claims. After reading this article, readers should be able to select a study design that best aligns with their particular research question and report their findings in ways that are faithful to the strengths of the study design. PMID- 29180146 TI - How-to-guide for writing multiple choice questions for the pharmacy instructor. AB - BACKGROUND: Writing multiple choice questions (MCQ) takes a lot of practice. Often, pharmacy practitioners lack the training to write effective MCQ. Sources for instruction in effective MCQ writing can be overwhelming with numerous suggestions of what should and should not be done. PURPOSE: The following guide is prepared to serve as a succinct reference for creation and revision of MCQ by both novice and seasoned pharmacy faculty practitioners. METHODS: The literature is summarized into 12 best practices for writing effective MCQ. Pharmacy specific examples that demonstrate violations of best practices and how they can be corrected are provided. IMPLICATIONS: The guide can serve as a primer to write new MCQ, as a reference to revise previously created questions, or as a guide to peer review of MCQ. PMID- 29180147 TI - Useful resources for members serving on a curriculum committee in schools and colleges of pharmacy. AB - The curriculum committee has an important role in the design and delivery of a Doctor of Pharmacy program. The primary purpose of this article is to identify relevant resources for members to utilize to be active participants in a school or college of pharmacy curriculum committee. The resources presented are focused around the following seven key curricular management concepts: orientation to curriculum, syllabus review, teaching methods, curriculum review, interprofessional education, student workload, and policy development, as these are common agenda items for a committee meeting. Several curricular resources used by other health care disciplines were included to promote collaboration with interprofessional education activities. Awareness of such resources may benefit members to achieve optimal educational outcomes for the program. PMID- 29180148 TI - Game on: The gamification of the pharmacy classroom. AB - BACKGROUND: Gamification is the use of game mechanics to promote engagement and enjoyment of problem-solving in non-game situations. Gamification has been used widely in recent years in industry and academia as a tool for training and education. OBJECTIVE: The aims of this paper are to provide an overview of gamification and digital game-based learning (DGBL), review the use of digital games in health professional education, and provide suggestions for future use in pharmacy curricula. DISCUSSION: Many examples of game-based learning in pharmacy and other health professional curricula have been published, however the body of literature on DGBL is less developed. Overall, evaluations of these techniques show that students find them engaging and enjoyable. A recent meta-analysis of studies comparing DGBL to non-game based learning in primary, secondary, post secondary education found that DGBL significantly enhances learning. Challenges to implementing game-based learning are financial, cultural, and technological. CONCLUSION: Many areas of the pharmacy curriculum could be appropriate for digital gamification. With more students entering pharmacy school familiar with video games and game-based living the time has come for pharmacy educators to explore how these instructional technologies could benefit a new generation of pharmacy students. As serious games are developed and researched in pharmacy curricula, test scores, student confidence in knowledge and skills, and retention of knowledge and skills are all outcomes that, if published, will help advance the adoption of DGBL into the pharmacy school classroom. PMID- 29180149 TI - Identifying motivators and barriers to student completion of instructor evaluations: A multi-faceted, collaborative approach from four colleges of pharmacy. AB - OBJECTIVE: To identify motivators and barriers to pharmacy student completion of instructor evaluations, and to develop potential strategies to improve the evaluation process. METHODS: Completed at four Ohio Colleges of Pharmacy, Phase I consisted of a student/faculty survey and Phase II consisted of joint student/faculty focus groups to discuss Phase I data and to problem solve. RESULTS: In Phase I, the top three student-identified and faculty-perceived motivators to completion of evaluations were to (1) make the course better, (2) earn bonus points, and (3) improve the instructor's teaching. The top three student-identified barriers to completion of evaluations were having to (1) evaluate multiple instructors, (2) complete several evaluations around the same time, and (3) complete lengthy evaluations. Phase II focus groups identified a number of potential ways to enhance the motivators and reduce barriers, including but not limited to making sure faculty convey to students that the feedback they provide is useful and to provide examples of how student feedback has been used to improve their teaching/the course. CONCLUSIONS: Students and faculty identified motivators and barriers to completing instructor evaluations and were willing to work together to improve the process. PMID- 29180150 TI - The impact of a research course on pharmacy students' perceptions of research and evidence-based practice. AB - BACKGROUND: Pharmacists need be able to understand and utilize evidence from the literature to provide optimal patient care as well as participate in research to improve care. Thus, it is important for pharmacy students to acquire skills in research and evidence-based practice (EBP). OBJECTIVES: To evaluate the changes in pharmacy student (1) perceptions of research and EBP, (2) interest in research participation, and (3) confidence in understanding the research process and developing a research proposal after completing a research course. METHODS: First year professional pharmacy students completed a required one-semester research course. Study objectives were assessed pre- and post-semester using a survey that contained seven demographic items, nine Research Perceptions items, and 17 Confidence in Research items (5-point Likert scale; 1 = not at all confident, and 5 = extremely confident). Two years of data were collected (2012: N = 49, 2013: N = 53) and analyzed using Wilcoxon signed-rank tests and Mann-Whitney U tests as appropriate. RESULTS: Significant improvements were seen in students' perceptions of the importance (2012: p = 0.022, 2013: p = 0.042) and usefulness of research (p = 0.022). Students' confidence significantly increased on all items for both years (p < 0.001). There was no significant change in student plans to perform or participate in future research. More students planned to use EBP in their practice post-semester in 2013 (p = 0.008). CONCLUSIONS: A research course can be an effective way to increase student confidence in research and improve perceptions on the importance and usefulness of research and EBP. It may not be an effective way to increase student interest in research as a career. PMID- 29180151 TI - Comparison of pharmacy students' knowledge and self-efficacy to provide cessation counseling for hookah and cigarette use. AB - OBJECTIVES: We aimed to assess pharmacy students' self-efficacy to provide cessation counseling for commercial cigarette and hookah tobacco use. METHODS: A cross-sectional study including PharmD students at a College of Pharmacy was conducted in Spring 2014. Confidence in counseling and perception of knowledge were self-rated and based on the Ask-Advise-Assess-Assist-Arrange follow-up (5A's) model and general tobacco cessation counseling skills. Comparisons were made between cigarettes and hookahs and by program level using t-tests, Wilcoxon signed-rank test, analyses of variance, and Tukey-Kramer tests. RESULTS: Overall, 82% and 16% of the students, respectively, reported receiving training on cigarette smoking and hookah tobacco use cessation. Students were moderately confident in their ability to counsel. Compared to hookah tobacco use cessation counseling, students were more confident in their general counseling skills and ability to counsel on cigarette smoking cessation using the 5A's (p < 0.001 in each case). Students perceived themselves to be more knowledgeable about cigarette smoking cessation than about hookah tobacco use cessation. Almost half of the students (42.0%) thought hookah tobacco was less harmful than traditional cigarettes. CONCLUSIONS: Pharmacy students need further training to address hookah and other alternative tobacco products to support patients' cessation needs, decrease risks for tobacco-related morbidity and mortality, and increase medication effectiveness. PMID- 29180152 TI - Benefits of a concentrated teaching rotation: Perspectives of pharmacy residents and faculty. AB - The postgraduate pharmacy residency experience requires residents to develop the proper skillset to not only provide optimal therapeutic management to patients, but to effectively deliver their knowledge to trainees and other health care providers. Without specific recommendations for how to achieve these skills, residents may hone their communication, organizational, and teaching skills through a number of different venues currently offered by residency programs nationwide. Residency programs commonly offer a longitudinal experience in order for residents to obtain didactic teaching skills; less often do programs offer a concentrated rotation dedicated to academia. Residents can acquire a number of skills from a focused academic rotation including curriculum development, career growth, and preceptorship by following a schedule that more closely mimics that of a clinical faculty member. These skills are typically more difficult to develop with a longitudinal experience due to time constraints and other resident and faculty member commitments. Prior to implementing this experience, the impact on both the resident and faculty member should be taken into consideration. PMID- 29180153 TI - Adaptation and psychometric validation of a scale to assess student pharmacists' beliefs in simplifying complicated medication regimens. AB - OBJECTIVES: To validate a scale in order to identify the most relevant survey constructs to measure student pharmacists' beliefs of providing a novel cognitive service of simplifying complicated medication regimens of community dwelling patients using a pill card. METHODS: A pre-existing scale was used to construct an adapted questionnaire in the context of simplifying complicated drug regimens in patients taking >five Rx meds daily. The adapted 14-item questionnaire was administered to 126 student pharmacists immediately after they performed a mandatory community pharmacy advanced pharmacy practice experience (APPE) exercise to simplify complicated drug regimens of patients. All students had rehearsed this service with standardized patients before their APPEs assignment. In this APPE assignment the student pharmacists consolidated the dose timings of the daily medications while attempting to improve their likelihood of efficacy and reduce their risk of adverse events. The psychometric properties of the adapted questionnaire were assessed using parallel analysis and principal component analysis. Internal consistency was established using Cronbach's alpha. RESULTS: Out of 126 students, 116 (92%) responded to the questionnaire. Factor analysis produced a 3-factor solution of the 14-item scale which accounted for 56% of the explained variance. The factors relate to self-efficacy (alpha = 0.956), intention to practice (alpha = 0.89) and mattering (alpha = 0.885). The overall internal consistency as measured by Cronbach's alpha was 0.936. The mean values obtained using these scales were 6.01 +/- 0.823, 4.88 +/- 0.742, and 4.45 +/- 0.556, respectively, indicating stronger beliefs in this cognitive service. CONCLUSIONS: The adapted 14-question instrument can be used to reliably measure the self-efficacy, intention and mattering of fourth-year student pharmacists who can simplify complicated drug regimens by consolidating routinely prescribed medications. PMID- 29180154 TI - Student use of flipped classroom videos in a therapeutics course. AB - PURPOSE: To evaluate the extent of student use of flipped classroom videos. METHODS: This was a cross-sectional study conducted in a college of pharmacy therapeutics course in the Unites States. In one section of the course (four sessions) all content was provided in the form of lecture videos that students had to watch prior to class. Class time was spent discussing patient cases. For half of the sessions, there was an electronic quiz due prior to class. The outcome measure was video view time in minutes. Adequate video view time was defined as viewing >=75% of total video duration. Video view time was compared with or without quizzes using the Wilcoxon signed-rank test. RESULTS: There were 100 students in the class and all were included in the study. Overall, 74 students had adequate video view time prior to session 1, which decreased to 53 students for session 2, 53 students for session 3, and 36 students for session 4. Median video view time was greater when a quiz was required [80 minutes (IQR: 38 114) versus 69 minutes (IQR: 3-105), p < 0.001]. The mean score on the exam was 84 +/- 8 points (out of 100). There was a significant association between video view time (per 50% increment) and score on the exam (coefficient 2.52; 95% CI: 0.79-4.26; p = 0.005; model R2 = 7.8%). CONCLUSION: Student preparation prior to the flipped classroom is low and decreases with time. Preparation is higher when there is a quiz required. PMID- 29180155 TI - The opinion of preceptors and students of very early IPPE rotations delivered concurrently with didactic courses. AB - INTRODUCTION: The Marshall University School of Pharmacy had the opportunity to create an experiential education program where IPPE education was introduced in their P1 year and was concurrent with didactic coursework. The School begins the delivery of experiential education as soon as the sixth week of the first professional year. OBJECTIVE: To ascertain the opinion of institutional preceptors, community preceptors, and students after the first academic year to discern viewpoints on the effectiveness and value of very early P1 experiential rotations. METHODS: Institutional and community preceptors and students were assessed by anonymous survey in order to ascertain their respective opinions regarding early P1 experiential education. The results of the preceptors were further divided into institutional and community practice sites. This study was approved by the Marshall University Institutional Review Board. RESULTS: Key findings demonstrated that early rotations were perceived as beneficial to the student by both community and institutional preceptors, as well as, the students themselves. CONCLUSIONS: Most, but not all, preceptors felt early rotations were beneficial to their practice and the student. Institutional preceptors were less likely to perceive a benefit to their practice or to the student than were community preceptors. Students were positive about the early experience. The results of these surveys regarding early experiential rotations should help minimize concerns of both preceptors and those assigned responsibility for constructing experiential programs about implementing early experiential rotations in the curriculum. PMID- 29180156 TI - Lesbian, gay, bisexual, and transgender inclusion: Survey of campus climate in colleges and schools of pharmacy. AB - BACKGROUND AND PURPOSE: To quantify the implementation of inclusive policies and benefits as well as institutional commitment to support LGBT faculty, staff, and students in pharmacy schools nationwide. EDUCATIONAL ACTIVITY AND SETTING: An anonymous, electronic survey was sent to administrators at 130 pharmacy schools. Forty-four survey responses were received, indicating a 34% response rate. The survey included questions relating to campus climate, inclusive policies and benefits, and institutional commitments to the LGBT community. FINDINGS: Approximately half of the survey respondents reported that their school has public written statements about diversity and multiculturalism that include sexual orientation and/or gender identity. About one-fifth of the respondents indicated that their school has inclusive materials for faculty, staff, and student information regarding sexual orientation and gender identity. Nearly one fourth of schools of pharmacy had participated in a voluntary LGBT training program, such as Safe Zone, Safe Space, or Ally Program. Over half of the respondents reported having access to LGBT organizations on campus, with two schools reporting having pharmacy organizations that specifically focus on LGBT student pharmacists and allies. Less than one-tenth of schools reported offering gender-neutral/single-occupancy restrooms and no schools reported knowledge of LGBT-related scholarships. SUMMARY: Room for improvement exists regarding the implementation of inclusive practices to improve campus climate for LGBT students, faculty, and staff. Areas with the largest room for improvement include accessible gender-neutral restrooms and availability of LGBT trainings, scholarships, and events. PMID- 29180157 TI - The development and piloting of "ATTEND DR," a clinical teaching tool to identify and prioritize potential causes of adverse drug reactions. AB - BACKGROUND: The identification, management, and reporting of adverse drug reactions are integral to clinical practice and education; however, undergraduate teaching related to adverse drug reactions may be inadequate for practice. Existing methods of causality assessment have a number of limitations in relation to clinical teaching, for example, they do not deal well with the concurrent use of other medications. OBJECTIVE: To develop and pilot a teaching tool to guide students through the process of identifying and prioritizing potential causes of an adverse drug reaction. SETTING: University-based School of Pharmacy, Australia: an undergraduate Quality Use of Medicines course. METHOD: A contrived acronym (mnemonic) was developed from causality assessments and discussions with practitioners. The acronym ATTEND DR (abnormality, taken, timeline, evidence, nothing else?, dose, dechallenge, and rechallenge) was piloted in workshops that focussed on adverse drug reactions and their management. Students' responses to "What did you find most valuable about today's workshop?" and "How could we improve?" were analyzed. RESULTS: All attendees responded (65/65). Students indicated that the ATTEND DR acronym was easy to remember, and facilitated causality assessment in a clinical context, due to an easily followed, step-by step, comprehensive process that was easy to remember. More practice case studies were requested. CONCLUSION: The ATTEND DR acronym was designed to address limitations of the existing methods of causality assessment in relation to clinical teaching and preparation of students for future clinical roles. Students responded favorably to its introduction, commenting that it was easily remembered and provided a comprehensive, clinically orientated, step-by-step process. PMID- 29180158 TI - Assessment of students' ability to incorporate a computer into increasingly complex simulated patient encounters. AB - BACKGROUND AND PURPOSE: Pharmacy students should be exposed to and offered opportunities to practice the skill of incorporating a computer into a patient interview in the didactic setting. Faculty sought to improve retention of student ability to incorporate computers into their patient-pharmacist communication. EDUCATIONAL ACTIVITY AND SETTING: Students were required to utilize a computer to document clinical information gathered during a simulated patient encounter (SPE). Students utilized electronic worksheets and were evaluated by instructors on their ability to effectively incorporate a computer into a SPE using a rubric. Students received specific instruction on effective computer use during patient encounters. Students were then re-evaluated by an instructor during subsequent SPEs of increasing complexity using standardized rubrics blinded from the students. FINDINGS: Pre-instruction, 45% of students effectively incorporated a computer into a SPE. After receiving instruction, 67% of students were effective in their use of a computer during a SPE of performing a pharmaceutical care assessment for a patient with chronic obstructive pulmonary disease (COPD) (p < 0.05 compared to pre-instruction), and 58% of students were effective in their use of a computer during a SPE of retrieving a medication list and social history from a simulated alcohol-impaired patient (p = 0.087 compared to pre instruction). DISCUSSION: Instruction can improve pharmacy students' ability to incorporate a computer into SPEs, a critical skill in building and maintaining rapport with patients and improving efficiency of patient visits. Complex encounters may affect students' ability to utilize a computer appropriately. Students may benefit from repeated practice with this skill, especially with SPEs of increasing complexity. PMID- 29180159 TI - Pharmacy students' use and perceptions of Apple mobile devices incorporated into a basic health science laboratory. AB - OBJECTIVE: To describe pharmacy students' use of mobile devices in a basic health science laboratory and to report the students' perceptions on how solving cases with their mobile devices influenced their attitudes, abilities, and view on the use of mobile devices as tools for pharmacists. METHODS: First-year pharmacy students utilized mobile devices to solve clinical case studies in a basic health sciences laboratory. A pre-survey and two post-surveys were administered to assess the students' comfort, awareness, use, and perceptions on the use of their mobile devices and apps. RESULTS: The pre-survey and first post-survey each had a response rate of 99%, and the second post-survey had a response rate of 100%. In comparing the pre-survey and first post-survey data, there was a statistically significant increase in the number of students that agreed or strongly agreed that they were more comfortable utilizing their mobile device (p = 0.025), they were more aware of apps for pharmacists (p < 0.005), and they have used more apps that can be useful for pharmacists (p < 0.005). The second post-survey demonstrated that over 78% of students agreed or strongly agreed that completing the case studies influenced them to be more comfortable with their mobile devices, to be more aware of apps that can be useful for pharmacists, and to be more agreeable with mobile device utilization by pharmacists in improving patient care. In addition, the second post-survey also demonstrated that 84% of students responded that using their mobile devices to solve the cases influenced them to either use their mobile device in a clinical setting for a clinical and/or pharmacy-related purpose for the first time or to use it more frequently for this purpose. CONCLUSIONS: The use of mobile devices to solve clinical cases in a first-year basic health science laboratory course was perceived as beneficial by students and influenced them to utilize their mobile device even more in a pharmacy practice setting. PMID- 29180160 TI - Predictors of student performance on the Pharmacy Curriculum Outcomes Assessment at a new school of pharmacy using admissions and demographic data. AB - OBJECTIVES: To characterize student performance on the Pharmacy Curriculum Outcomes Assessment (PCOA) and to determine the significance of specific admissions criteria and pharmacy school performance to predict student performance on the PCOA during the first through third professional years. METHODS: Multivariate linear regression models were developed to study the relationships between various independent variables and students' PCOA total scores during the first through third professional years. RESULTS: To date, four cohorts have successfully taken the PCOA examination. Results indicate that the Pharmacy College Admissions Test (PCAT), the Health Science Reasoning Test (HSRT), and cumulative pharmacy grade point average were the only consistent significant predictors of higher PCOA total scores across all students who have taken the exam at our school of pharmacy. CONCLUSION: The school should examine and clarify the role of PCOA within its curricular assessment program. Results suggest that certain admissions criteria and performance in pharmacy school are associated with higher PCOA scores. PMID- 29180161 TI - Implementing professionalism by deprofessionalized strategies: A moral quandary. AB - Monetary fine proceedings has been one of the methods of upholding professionalism amongst health care professionals. Professionalism as a concept is multifaceted and fragmented and it has become symbolic to the extent that, unfortunately, some traits of professionalism showcase the whole concept. It seems fair to interpret the symbolic views on the concept of professionalism as means to capitalize on certain aspects of professions such as commercial profitability for the employer and respected status for the profession. Evaluation of professionalism is often implicit and inadequate; and assessing professionalism by relying on abstract and idealized definitions implies that professionalism is a compounded composite of certain set of stable traits. We suggest to refer to the theory of values-based practice so as to achieve collocated views on professionalism among employers and health academics. Instead of capitalizing on certain traits of professionalism to project the whole concept of professionalism, we may need to relook at the traits of professionalism as values. It is extremely crucial to internalize the values of the health profession in the future health professionals, so that the future health professionals imbibe the professionalism through dialog and democratic methods of sharing values during the course of professional development. PMID- 29180162 TI - Using a community theatre as a self-directed introductory pharmacy practice experience (SD IPPE) site. AB - OBJECTIVE: To describe a novel setting and method for self-directed introductory pharmacy practice experiences (SD IPPE). METHODS: Students presented health care information relative to the plot of a production at a local community theater throughout the season. Students developed a poster and handout that were presented in the theater lobby prior to each production. ASSESSMENT: A six question survey was provided to students after each presentation that identified their perceived benefit to play patrons and their overall experience using a 5 point Likert scale. IMPLICATIONS: Completing SD IPPE in a theater is a novel and innovative concept. Data suggest that students prefer presenting information in non-traditional settings. Students felt their work enhanced the theatrical experience of patrons. Results demonstrate that the theater is a viable setting for future presentations that benefit both students and public. PMID- 29180163 TI - A needs assessment of pharmacokinetic skills performed on advanced pharmacy practice experiences by student pharmacists. AB - INTRODUCTION: Pharmacokinetic (PK) calculations are an important competency for pharmacy students, however, there is little to guide which medications should be included in pharmacy curricula. Additionally, many new medications require therapeutic drug monitoring (TDM)-but not PK calculations-to ensure safe use. The objectives of this study were to quantify which medications are most frequently encountered by pharmacy students during advanced pharmacy practice experiences (APPE's) and to what extent PK calculations or TDM were completed by students while on APPE's at the University of New England. METHODS: Fourth-year students were surveyed upon completion of their advanced pharmacy practice experiences (APPE's). RESULTS: Pharmacokinetic calculations occurred most frequently on institutional rotations. Vancomycin and aminoglycosides were the two most common medications pharmacy students were asked to perform PK calculations for while on APPE's. Therapeutic drug monitoring occurred most frequently on institutional rotations. Therapeutic drug monitoring also occurred more often than pharmacokinetic monitoring on ambulatory care rotations. CONCLUSIONS: Pharmacokinetic calculations as well as therapeutic drug monitoring requiring no calculations were both commonly encountered by student pharmacists while on APPE rotations. Changes to clinical guidelines have impacted the types of medications students are expected to have proficiency with, and more broadly defined therapeutic drug monitoring competencies may be important for ambulatory care APPE's. PMID- 29180164 TI - Th-17 cytokines are associated with severity of Trypanosoma cruzi chronic infection in pediatric patients from endemic areas of Mexico. AB - In Chagas disease the clinical, acute and chronic manifestations are the result of the interaction between the parasite and the host factors. The balance between inflammatory and anti-inflammatory immune responses is essential for the increase or resolution of the manifestations in individuals infected with T. cruzi. To identify if children with chronic Chagas disease and heart injury is related with non-regulated Th1, Th2 and Th17 responses. We included 31 children with T. cruzi confirmed chronic infection from endemic areas of Mexico. Subsequently, they were separated according to their ECHO and ECG results into three groups according to the severity of cardiac involvement. Circulating Th1, Th2 and Th17 cytokine profiles were performed by Luminex assays and the results were analyzed by bivariate and multivariable analysis. Patients were classified in asymptomatic chronic (group 1, N=12); individuals with IRBBB in ECG and incipient lesions in ECHO (Group 2, N=8) and Patients with severe chronic symptomatic disease (Group 3, N=11). The analysis of immune mediators revealed that patients with severe cardiac manifestations had significant higher levels (p <0.05) of Th17 related cytokines including IL-17 and IL-6 as well as IFN-gamma and IL-2. Also patients with severe cardiomyopathy exhibit increased levels of IL-13 (p <0.05) after multivariate analysis. High levels of Th17 related cytokines including IL-17, IFN gamma, IL-6 and IL-2 and pro-fibrotic factors such as IL-13 could be associated to the severity of cardiac involvement in children with chronic T. cruzi infection. These cytokines could be useful as indicators for the early identification of cardiac damage associated to the T. cruzi infection. PMID- 29180165 TI - Photolabile ruthenium complexes to cage and release a highly cytotoxic anticancer agent. AB - CHS-828 (N-(6-(4-chlorophenoxy)hexyl)-N'-cyano-N"-4-pyridyl guanidine) is an anticancer agent with low bioavailability and high systemic toxicity. Here we present an approach to improve the therapeutic profile of the drug using photolabile ruthenium complexes to generate light-activated prodrugs of CHS-828. Both prodrug complexes are stable in the dark but release CHS-828 when irradiated with visible light. The complexes are water-soluble and accumulate in tumour cells in very high concentrations, predominantly in the mitochondria. Both prodrug complexes are significantly less cyototoxic than free CHS-828 in the dark but their toxicity increases up to 10-fold in combination with visible light. The cellular responses to light treatment are consistent with release of the cytotoxic CHS-828 ligand. PMID- 29180166 TI - Highlights from the 20th Workshop on Vitamin D in Orlando, Mar. 28-31, 2017. PMID- 29180167 TI - Characterization of equine GST A3-3 as a steroid isomerase. AB - Glutathione transferases (GSTs) comprise a superfamily of enzymes prominently involved in detoxication by making toxic electrophiles more polar and therefore more easily excretable. However some GSTs have developed alternative functions. Thus, a member of the Alpha class GSTs in pig and human tissues is involved in steroid hormone biosynthesis, catalyzing the obligatory double-bond isomerization of Delta5-androstene-3,17-dione to Delta4-androstene-3,17-dione and of Delta5 pregnene-3,20-dione to Delta4-pregnene-3,20-dione on the biosynthetic pathways to testosterone and progesterone. The human GST A3-3 is the most efficient steroid double-bond isomerase known so far in mammals. The current work extends discoveries of GST enzymes that act in the steroidogenic pathways in large mammals. The mRNA encoding the steroid isomerase GST A3-3 was cloned from testis of the horse (Equus ferus caballus). The concentrations of GSTA3 mRNA were highest in hormone-producing organs such as ovary, testis and adrenal gland. EcaGST A3-3 produced in E. coli has been characterized and shown to have highly efficient steroid double-bond isomerase activity, exceeding its activities with conventional GST substrates. The enzyme now ranks as one of the most efficient steroid isomerases known in mammals and approaches the activity of the bacterial ketosteroid isomerase, one of the most efficient enzymes of all categories known today. The high efficiency and the tissue distribution of EcaGST A3-3 support the view that the enzyme plays a physiologically significant role in the biosynthesis of steroid hormones. PMID- 29180168 TI - Inhalable particulate drug delivery systems for lung cancer therapy: Nanoparticles, microparticles, nanocomposites and nanoaggregates. AB - There is progressive evolution in the use of inhalable drug delivery systems (DDSs) for lung cancer therapy. The inhalation route offers many advantages, being non-invasive method of drug administration as well as localized delivery of anti-cancer drugs to tumor tissue. This article reviews various inhalable colloidal systems studied for tumor-targeted drug delivery including polymeric, lipid, hybrid and inorganic nanocarriers. The active targeting approaches for enhanced delivery of nanocarriers to lung cancer cells were illustrated. This article also reviews the recent advances of inhalable microparticle-based drug delivery systems for lung cancer therapy including bioresponsive, large porous, solid lipid and drug-complex microparticles. The possible strategies to improve the aerosolization behavior and maintain the critical physicochemical parameters for efficient delivery of drugs deep into lungs were also discussed. Therefore, a strong emphasis is placed on the approaches which combine the merits of both nanocarriers and microparticles including inhalable nanocomposites and nanoaggregates and on the optimization of such formulations using the proper techniques and carriers. Finally, the toxicological behavior and market potential of the inhalable anti-cancer drug delivery systems are discussed. PMID- 29180169 TI - Sarcopenia in children with perforated appendicitis. AB - BACKGROUND: Decreased skeletal muscle mass, or sarcopenia, has been shown to be associated with worse postoperative recovery and a higher risk of complications in adult surgical patients. We hypothesized that pediatric patients with complicated appendicitis may experience sarcopenic changes over the course of their treatment. METHODS: The medical records and computed tomography scans of 36 pediatric complex appendicitis patients who had both preoperative and postoperative computerized tomography scans at our hospital were reviewed. Changes in psoas muscle area were examined using linear mixed models with random patient-level intercept and time effects. RESULTS: The median change in body mass index among all patients from admission to discharge was -0.8 kg/m2 (interquartile range: -1.3 to -0.2). The mean percentage change in psoas muscle area per day over the course of appendicitis-related treatment was -0.81% (95% confidence interval: -1.12 to -0.50) (P < 0.001). The relative decrease in psoas muscle area per day did not vary by initial body mass index, gender, or race (P > 0.10 for all interactions). CONCLUSIONS: Our data suggest that pediatric patients with complex appendicitis experience sarcopenic changes during their hospital admission. Given previous reports that sarcopenia is a significant predictor of worse surgical outcomes, more investigation is warranted to assess whether these changes are associated with postsurgical complications and to evaluate potential interventions that may prevent these changes. PMID- 29180170 TI - Money well spent? A cost and utilization analysis of prophylactic inferior vena cava filter placement in high-risk trauma patients. AB - BACKGROUND: Inferior vena cava filters (IVCF) for venous thromboembolic prophylaxis in high-risk trauma patients is a controversial practice. Utilization of IVCF prophylaxis was evaluated at a level 1 trauma center. Daily cost of IVCF prophylaxis, time to IVCF, duration between IVCF and chemoprophylaxis, and number of patients needed to treat (NNT) to prevent pulmonary embolism (PE) was calculated. METHODS: A retrospective review of prophylactic IVCF over a 5-year period (2010-2014). Demographic, physiologic, injury, procedural, and outcome data were abstracted from the administrative trauma database. Medicare fees and days without chemoprophylaxis were used to determine daily IVCF cost. NNT was calculated using PE events in a cohort without IVCF. RESULTS: Over the 5-year period, 146 patients with mean age 56.3 y (SD +/- 24.2), 67.8% male, underwent prophylactic IVCF. Predominant mechanisms of injuries were falls (45.9%) and motor vehicle accidents (20.5%) with median Injury Severity Score of 25 (intraquartile range [IQR] 16-29) and head Abbreviated Injury Score of 3 (IQR 3 5). Most common operative interventions required in 24.7% were orthopedic (25.3%) and neurosurgical (21.9%). Median time to IVCF was 78 h (IQR 48-144). Most common IVCF indications were closed head injury (48.6%) and spinal injuries (30.8%). Median time to administration of chemoprophylaxis was 96 h after IVCF (IQR 24 192) in 57.5%. Median IVCF cost was $759/d (IQR $361-$1897) compared with $4.32 for chemoprophylaxis. PE occurred in 0.26% without IVCF. PE did not occur with prophylactic IVCF. Estimated NNT was 379 (95% CI 265, 661). CONCLUSIONS: Prophylactic IVCF placement is a costly practice with relatively low benefit. Anticipated time without chemoprophylaxis and patient criteria should be considered before routine IVCF placement. PMID- 29180171 TI - The long-term outcomes of thyroid function after subtotal thyroidectomy for Graves' hyperthyroidism. AB - BACKGROUND: Surgical management of Graves' disease (GD) is changing from subtotal to total thyroidectomy because the latter eliminates the risk of recurrence. However, to preserve thyroid function in a euthyroid state, subtotal thyroidectomy is still performed for GD in non-Western countries. Therefore, we designed a study to investigate the long-term outcomes in GD patients after subtotal thyroidectomy and the correlation between remnant weight and postoperative thyroid function. MATERIALS AND METHODS: This was a retrospective cohort observation study. Between January 2005 and December 2011, 415 consecutive GD patients treated by subtotal thyroidectomy were enrolled. All data were collected from 385 patients who underwent bilateral subtotal thyroidectomy and 57 patients who underwent the Hartley-Dunhill operation. The median postoperative follow-up time was 72 months (range 12-144 months). RESULTS: The mean weight of the preserved thyroid remnant was 5.1 g. Persistent or recurrent hyperthyroidism was observed in 119 (28.7%) patients. The median time of recurrence was 36 months (range 12-120 months). Hypothyroidism developed in over 50% of patients. A euthyroid state was achieved in only 19.3% of patients, and the rate did not increase significantly as remnant weight increased. Based on a Cox regression analysis, the remnant weight is an independent risk factor for persistent or recurrent hyperthyroidism (hazard ratio: 1.323, 95% confidence interval: 1.198 1.461, P < 0.001). CONCLUSIONS: Subtotal thyroidectomy with the intent to maintain a euthyroid state is not an optimal surgical strategy for the definitive treatment of GD because the persistence or recurrence rate is high and the euthyroid rate is lower than expected. PMID- 29180172 TI - Early appendectomy reduces costs in children with perforated appendicitis. AB - BACKGROUND: Perforated appendicitis can be managed with early appendectomy, or nonoperative management followed by interval appendectomy. We aimed to identify the strategy with the lowest health care utilization and cost. METHODS: We retrospectively reviewed the medical records of all children <=18 years old with perforated appendicitis admitted to a single institution between January 2009 and March 2016. After excluding immunosuppressed patients and transfers from outside hospitals, we grouped the remaining patients by early or interval appendectomy. Cost accounting data were obtained from our institutional database. The primary outcome was total hospital cost over 2 y from initial admission for appendicitis. Other outcomes analyzed included initial admission costs, number of admissions, emergency room and clinic visits, percutaneous procedures, cross-sectional and overall imaging studies, and length of stay. RESULTS: A total of 203 children with perforated appendicitis were identified. After exclusion of immunosuppressed patients and outside hospital transfers, 94 patients were included in the study. Thirty-nine underwent early appendectomy and 55 initial nonoperative management; of these, 54 underwent elective interval appendectomy. Five of 55 patients (9%) failed initial nonoperative management and required earlier-than-planned appendectomy. Total cost over 2 y was significantly lower with early appendectomy than initial nonoperative management ($19,300 +/- 14,300 versus $26,000 +/- 17,500; P = 0.05). Early appendectomy resulted in fewer hospital admissions, clinic visits, invasive procedures, and imaging studies. CONCLUSIONS: Early appendectomy results in lower hospital costs and less health care utilization compared with initial nonoperative management with elective interval appendectomy. A prospective study will shed more light on this question and can assess the role of nonoperative management without interval appendectomy in children with perforated appendicitis. PMID- 29180173 TI - Greater lymph node retrieval and lymph node ratio impacts survival in resected pancreatic cancer. AB - BACKGROUND: Surgical resection is the mainstay of pancreatic cancer treatment; however, the ideal lymphadenectomy remains unsettled. This study sought to determine whether number of examined lymph nodes (eLNs) and lymph node ratio (LNR) impact survival. METHODS: The U.S. National Cancer Data Base (2003-2011) was reviewed for patients who underwent initial resection for clinical stage I and II pancreatic adenocarcinoma. Univariate and multivariate survival analyses were performed. RESULTS: Of 14,007 patients, 15.6% had 0-6 eLN, 27.1% 7-12, 13.4% 13-15, and 38.6% > 15 eLN. Median eLN was 11 for pancreaticoduodenectomy, and 14 for distal, total pancreatectomy, or other procedure. ELN >15 was associated with significantly improved survival in both node negative and positive disease (P < 0.001, both). In multivariable analysis, 7-12, 13-15, and >15 eLN had improved survival relative to 0-6 eLN (HR 0.87, P < 0.001, HR 0.89, P = 0.002, HR 0.82, P < 0.001, respectively). A total of 34.5% of patients had an LNR of 0, 31.5% <= 0.2, 20.3% 0.2-0.4, 11.7% 0.4-0.8, and 2.0% had an LNR >0.8. Patients with LNR 0 had improved survival in T1-T3 disease (P < 0.01). In multivariable analysis, higher LNR was negatively associated with survival (LNR 0-0.2: HR 1.44, P < 0.001, LNR 0.2-0.4: HR 1.82, P < 0.001, LNR 0.4-0.8: 2.03, P < 0.001, LNR >0.8, P < 0.001). Even with suboptimal eLN (eLN <=6 or <=12), higher LNR remained an independent predictor of mortality. CONCLUSIONS: Greater lymph node retrieval in stage I & II pancreatic adenocarcinoma may have prognostic value, even in node negative disease. Lymph node ratio is inversely related to survival and may be useful with suboptimal eLN. PMID- 29180174 TI - Formalin-fixed paraffin-embedded sample conditions for deep next generation sequencing. AB - INTRODUCTION: Precision medicine is only possible in oncology practice if targetable genes in fragmented DNA, such as DNA from formalin-fixed paraffin embedded (FFPE) samples, can be sequenced using next generation sequencing (NGS). The aim of this study was to examine the quality and quantity of DNA from FFPE cancerous tissue samples from surgically resected and biopsy specimens. METHODS: DNA was extracted from unstained FFPE tissue sections prepared from surgically resected specimens of breast, colorectal and gastric cancer, and biopsy specimens of breast cancer. A total quantity of DNA >=60 ng from a sample was considered adequate for NGS. The DNA quality was assessed by Q-ratios, with a Q-ratio >0.1 considered sufficient for NGS. RESULTS: The Q-ratio for DNA from FFPE tissue processed with neutral-buffered formalin was significantly better than that processed with unbuffered formalin. All Q-ratios for DNA from breast, colorectal and gastric cancer samples indicated DNA levels sufficient for NGS. DNA extracted from gastric cancer FFPE samples prepared within the last 7 years is suitable for NGS analysis, whereas those older than 7 years may not be suitable. Our data suggested that adequate amounts of DNA can be extracted from FFPE samples, not only of surgically resected tissue but also of biopsy specimens. CONCLUSIONS: The type of formalin used for fixation and the time since FFPE sample preparation affect DNA quality. Sufficient amounts of DNA can be extracted from FFPE samples of both surgically resected and biopsy tissue, thus expanding the potential diagnostic uses of NGS in a clinical setting. PMID- 29180175 TI - YouTube as a source of information for patients considering surgery for ulcerative colitis. AB - BACKGROUND: With the range of health information online, assessing the resources that patients access may improve the content of preoperative information. Our aim was to assess the content of the most viewed videos on YouTube related to surgery for ulcerative colitis (UC). METHODS: YouTube was searched for videos containing information on surgery for UC. The 50 most viewed videos were identified and user interaction analyzed. Upload source was classified as patient, individual health care professional (HCP), or hospital/professional association. Video content was categorized using an inductive thematic analysis on a purposive sample list of videos. The overarching theme of each video was classified once data saturation was achieved. RESULTS: Thirty videos were uploaded by patients, 15 by hospitals and 5 by HCPs. Seventeen videos (34%) discussed life after surgery. Sixteen of these were uploaded by patients who had previously undergone surgery for UC. No videos of this theme were uploaded by HCPs. Ten videos (20%) described a number of different operations. Other themes identified were alternative health therapies (12%), colonoscopy (12%), life with UC (8%), miscellaneous (8%), and education for HCPs (6%). Patient uploaded videos had significantly more comments (P = 0.0079), with 28% of comments on patient videos being users requesting further information. CONCLUSIONS: Understanding the sequelae of surgery is most important to preoperative patients. There are a lack of professional videos addressing this topic on YouTube. HCPs must participate in the production of videos and adapt preoperative consultations to address common preoperative concerns. PMID- 29180176 TI - Magnetic transcutaneous fixation: an experimental study in pigs. AB - BACKGROUND: Magnetic subdermal implants have never been studied in the context of magnetic fixation of an external device to the body's surface. Excessive attractive force between the implant and the external device may compromise local circulation due to mechanical compression, leading to necrosis. OBJECTIVE: To evaluate the feasibility of transcutaneous magnetic fixation and assess secondary skin changes when subjected to a continuous static magnetic field. METHODS: Using the pig as an animal model, 72 implants were introduced in 12 animals. After wound healing, ultrasonography was performed to measure implant depths. Computer simulations were applied to allow magnetic attachment between implants and external devices without impairing local blood flow. External devices of different magnetic strengths were applied over the skin for 7 days. Local skin was examined and collected for analysis. A senior dermatopathologist blindly examined skin specimens and controls for abnormal findings, measuring dermal and epidermal thickness. Statistical analysis (P <0.05) was performed over the data. RESULTS: Nineteen implants presented extrusion. The remaining 53 skin sites underwent magnetic compression, of which 43 (81%) evolved uneventfully. Implant depth varied between 4.6 mm and 8.3 mm (5.8 mm; +/- 8.6 mm) with estimated pressure levels between 13.28 mmHg and 37.04 mmHg (27.6 mmHg; +/-6.0 mmHg). Stronger magnets were associated with an increase in dermal thickness (P = 0.011) and neovascularization (P = 0.045). CONCLUSIONS: Transcutaneous magnetic fixation is compatible with skin viability in vivo, under experimental conditions. Skin interposition between two permanent magnets resulted in a continuous static magnetic field stimulation, which showed similar effects to pulsed electromagnetic fields reported on scientific literature. PMID- 29180177 TI - Cutting electrocautery versus scalpel for surgical incisions: a systematic review and meta-analysis. AB - BACKGROUND: Although cutting electrocautery can be superior to the scalpel in reducing blood loss and incisional time, several reports associated electrocautery with higher rates of wound infection, impaired healing, and worse cosmesis. We performed this systematic review and meta-analysis to compare cutting electrocautery versus scalpel for surgical incisions. MATERIALS AND METHODS: We conducted a computerized literature search of five electronic databases and included all published original studies comparing cutting electrocautery and scalpel surgical incisions. Relevant data were extracted from eligible studies and pooled as odds ratios (ORs) or standardized mean difference (SMD) values in a meta-analysis model, using RevMan and Comprehensive Meta analysis software. RESULTS: Forty-one studies (36 randomized trials, four observational, and one quasirandom study) were included in the pooled analysis (6422 participants). Compared with the scalpel incision, cutting electrocautery resulted in significantly less blood loss (SMD = -1.16, 95% CI [-1.60 to -0.72]), shorter incisional (SMD = -0.63, 95% CI [-0.96 to -0.29]) and operative times (SMD = -0.59, 95% CI [-1.12 to -0.05]), and lower pain scores (SMD = -0.91, 95% CI [-1.27 to -0.55]) with no significant differences in terms of wound infection rates (OR = 0.92, 95% CI [0.74-1.15]) or overall subjective scar score (SMD = 0.49, 95% CI [-1.72 to 0.75]). CONCLUSIONS: Surgical incision using electrocautery can be quicker with less blood loss and postoperative pain scores than the scalpel incision. No statistically significant difference was found between both techniques in terms of postoperative wound complications, hospital stay duration, and wound cosmetic characteristics. Therefore, we recommend routine use of cutting electrocautery for surgical incisions. PMID- 29180178 TI - Telemedicine broadening access to care for complex cases. AB - BACKGROUND: Surgical and nonsurgical specialists are highly centralized, making access to high-quality care difficult for many Americans. We explored the feasibility, benefits, preliminary outcomes, and patient satisfaction with a new type of health visit, in which a surgical oncologist used video telecommunication to manage and treat complex cancer diseases, including patients with severe comorbidities. MATERIALS AND METHODS: Patients visited local VA medical centers throughout Florida to engage in video telecommunication visits with a centralized surgical oncologist in Miami, who directed their oncology treatment. The average length of stay and rate of unplanned readmission were calculated within each organ. The total mileage saved was calculated by subtracting the distance between the patient's home address and the local VA from the distance between the patient's home address and the Miami VA. Travel costs were determined by the VA's reimbursement of $0.415/mile for health-related travel and reimbursement of $150.00 for an overnight hotel stay. A Likert scale with both positively and negatively keyed questions was used to assess patient satisfaction. RESULTS: In 24 mo, seven unplanned readmissions occurred among 195 operations. Patients experienced an 80.7% reduction in travel distance and saved a total of 213,007.58 miles by visiting their local VA instead of the Miami VA. Survey results indicate that 86% of patients believed that the telemedicine program made medical care more accessible. CONCLUSIONS: The Specialist-Directed Telemedicine Model can save patients substantial time and money by not traveling to centralized areas, while delivering greater continuity of care and patient satisfaction. PMID- 29180179 TI - Preoperative thrombelastography maximum amplitude predicts massive transfusion in liver transplantation. AB - BACKGROUND: Massive transfusion (MT) is frequently required during liver transplantation. Risk stratification of transplant patients at risk for MT is an appealing concept but remains poorly developed. Thrombelastography (TEG) has recently been shown to reduce mortality when used for trauma resuscitation. We hypothesize that preoperative TEG can be used to risk stratify patients for MT. MATERIAL AND METHODS: Liver transplant patients had blood drawn before surgical incision and assayed via TEG. Preoperative TEG measurements were collected in addition to standard laboratory coagulation tests. TEG variables including R-time (reaction time), angle, maximum amplitude (MA), and LY30 (clot lysis 30 min after MA) were correlated to red blood cell units, plasma (fresh frozen plasma), cryoprecipitate, and platelets during the first 24 h after surgery and tested for their performance using a receiver-operating characteristic curve. RESULTS: Twenty-eight patients were included in the analysis with a median Model for End Stage Liver Disease score of 17; 36% received a MT. The TEG variables associated with MT (defined as >=10 red blood cell units/24 h) were a low MA (P < 0.001) and low angle (P = 0.014). A high international normalized ratio of prothrombin time (P = 0.003) and low platelet count (P = 0.007) were also associated with MT. MA had the highest area under the curve (0.861) followed by international normalized ratio of prothrombin time (0.803). An MA of less than 47 mm has a sensitivity of 90% and specificity of 72% to predict a MT. MA was the only coagulation variable that correlated strongly to all blood products transfused. CONCLUSIONS: TEG MA has a high predictability of MT during liver transplantation. The use of TEG preoperatively may help guide more cost effective blood bank preparation for this procedure as only a third of patients required a MT. PMID- 29180180 TI - Primary repair for pediatric colonic injury: Are there differences among adult and pediatric trauma centers? AB - BACKGROUND: Management of colonic injuries (colostomy [CO] versus primary anastomosis [PA]) among pediatric patients remains controversial. The aim of this study was to assess outcomes in pediatric trauma patient with colonic injury undergoing operative intervention. METHODS: The National Trauma Data Bank (2011 2012) was queried including patients with isolated colonic injury undergoing exploratory laparotomy with PA or CO with age <=18 y. Missing value analysis was performed. Patients were stratified into two groups: PA and CO. Outcome measures were mortality, in-hospital complications, and hospital length of stay. Multivariate regression analysis was performed. RESULTS: A total of 1151 patients included. Mean +/- standard deviation age was 11.61 +/- 2.8 y, and median [IQR] Injury Severity Score was 12 [8-16]; 39% (n = 449) of the patients had CO, and 35.6% (n = 410) were managed in pediatric trauma centers (PC). Patients with CO had a higher Injury Severity Score (P < 0.001), a trend toward lower blood pressure (P = 0.40), and an older age (P < 0.001). There was no difference in mortality between the PA and CO groups. However, patients who underwent PA had a shorter length of stay (P < 0.001) and lower in-hospital complications (P < 0.001). A subanalysis shows that, after controlling for all confounding factors, patients managed in PC were 1.2 times (1.2 [1.1-2.1], P = 0.04) more likely to receive a CO than those patients managed in adult trauma centers (AC). Moreover, there was no difference in mortality between the AC and the PC (P = 0.79). CONCLUSIONS: Our data demonstrate no difference in mortality in pediatric trauma patients with colonic injury who undergo primary repair or CO. However, adult trauma centers had lower rates of CO performed as compared to a similar cohort of patients managed in pediatric trauma centers. Further assessment of the reasons underlying such differences will help improve patient outcomes. PMID- 29180181 TI - Marked stem/progenitor cell expansion occurs early after murine ileostomy: a new model. AB - BACKGROUND: Improving treatment for short bowel syndrome requires a better understanding of how intestinal adaptation is affected by factors like mechanoluminal stimulation. We hypothesized that in mice, luminal diversion via an ileostomy would drive adaptive changes similar to those seen in human intestine after diversion while offering the opportunity to study the immediate events after resection that precede intestinal adaptation. MATERIALS AND METHODS: With Institutional Animal Care and Use Committee approval, a distal ileostomy with a long distal Hartman's was created in 9- to 14-week-old C57/B6 mice (n = 8). Control mice only had a midline laparotomy without stoma formation (n = 5). A rim of tissue from the proximal stoma was resected as a historical control for the proximal segment. Postoperatively, mice received a high-protein liquid diet and water ad libitum. On day 3, tissue from both the proximal and distal limbs were collected for histologic and RNA analysis. Morphometric measures, immunofluorescent antigen detection, and RNA expression were compared with Student paired t-tests with a P value < 0.05 considered significant. RESULTS: At 3 d, survival for mice with an ileostomy was 87% and average weight loss was 12.5% of initial weight compared to 6.05% for control mice. Compared to the distal limb, the proximal limb in mice with an ileostomy demonstrated significantly taller villi with deeper and wider crypts. The proximal limb also had decreased expression of intestinal stem cell markers lgr5, bmi1, sox9, and ascl2. Fewer goblet and enteroendocrine cells per hemivillus were also noted in the proximal limb. In control mice, none of these measures were significant between proximal and distal ileum except for villus height. CONCLUSIONS: This new murine ileostomy model allows study of intestinal adaptation without intestinal anastomosis, which can be technically challenging and morbid. PMID- 29180182 TI - Perioperative warming, oxygen, and Ilomedin on oxygenation and healing in infrainguinal bypass surgery. AB - BACKGROUND: Perioperative adjuncts are utilized across surgical specialities with the goal of improving patient outcomes. High-dose oxygen and extended warming are shown to increase wound collagen deposition during abdominal surgery. Prostacyclin is shown to improve limb salvage and patency rate in infrainguinal bypass (IIB) surgery. This study evaluated the impact of these adjuncts on healing and perfusion post IIB surgery. METHODS: This randomized controlled study allocated patients undergoing IIB surgery into three treatment arms (perioperative high-dose oxygen, extended warming, and a synthetic prostacyclin) or a control group. The primary outcome was accumulation of hydroxyproline (OHP, collagen surrogate marker) as collected in polytetrafluoroethylene implants on day 5. Secondary outcomes included levels of growth factors and cytokines, and tissue oxygenation of the wound and foot as measured by hyperspectral technology and ankle-brachial pressure index. Clinical outcomes were observed to day 30, with long-term follow-up of 12 mo. RESULTS: Seventy-one patients completed the study. Comparing treatment groups with the control at day 5, there were no differences in OHP, growth factors or cytokines levels, or improvement in tissue oxygenation at the surgical incision. However, there was more flow to the foot (HT-SUM (%) change) in the Ilomedin group compared to control (0% versus -14.6%, P = 0.045). HT-deoxy was higher at the peripheries in the oxygen and temperature groups, suggesting decreased tissue oxygenation. CONCLUSIONS: The perioperative treatments did not dramatically improve oxygenation or healing of the surgical wound in IIB surgery; however, Ilomedin may result in greater flow to the peripheries. PMID- 29180183 TI - Timing of valproic acid in acute lung injury: prevention is the best therapy? AB - BACKGROUND: Acute lung injury and respiratory distress syndrome is characterized by uncontrolled inflammation of the lungs after a severe inflammatory stimulus. We have previously demonstrated an ameliorated syndrome and improved survival in mice with early administration of valproic acid (VPA), a broad-spectrum histone deacetylase inhibitor, while studies in humans have shown no benefit when anti inflammatories are administered late. The current study tested the hypothesis that early treatment would improve outcomes in our gram-negative pneumonia induced acute lung injury. MATERIALS AND METHODS: Mice (C57BL/6) had 50 * 106 Escherichia coli (strain 19,138) instilled endotracheally and VPA (250 mg/kg) administered intraperitoneally 3, 4, 6, and 9 h (n = 12/group) later. Six hours after VPA administration, the animals were sacrificed, and bronchoalveolar lavage (BAL) fluid interleukin-6 (IL-6), tumor necrosis factor, neutrophils and macrophages as well as the E coli colony-forming units were quantified. Plasma IL 6 was also measured. A separate group of mice (n = 12/group) were followed prospectively for 7 days to assess survival. RESULTS: BAL IL-6 and tumor necrosis factor as well as plasma IL-6 were significantly lower in the animals administered VPA within 3 h (P < 0.05) but not when administered later (4, 6, 9 h). There was no difference in the BAL E coli colony-forming units, macrophage, or neutrophil numbers at any time point. Survival improved only when VPA was administered within 3 h. CONCLUSIONS: A narrow therapeutic window exists in this murine model of gram-negative pneumonia-induced acute lung injury and likely explains the lack of response in studies with late administration of anti inflammatory therapies in clinical studies. PMID- 29180184 TI - Status of trauma quality improvement programs in the Americas: a survey of trauma care providers. AB - INTRODUCTION: Global disparities in trauma care contribute to significant morbidity and mortality (M&M) in low- and middle-income countries. Implementation of quality improvement (QI) programs has been shown to be a cost-effective strategy to improve trauma care quality. In this study, we aim to characterize the trauma QI programs in a broad range of low- to high-income countries in the Americas to assess areas for targeted improvement in global trauma QI efforts. METHODS: We conducted a mixed methods survey of trauma care providers in North and South America distributed in-person at trauma care conferences and online via a secure survey platform. Responses were analyzed to observe differences across respondent country income categories. RESULTS: One hundred ninety-two surveys were collected, representing 21 different countries from three income strata (three lower-middle-, eleven upper-middle-, and eight high-income countries). Respondents were primarily physicians or physicians-in-training (85%). Eighty nine percent of respondents worked at an institution where M&M conferences occurred. M&M conferences were significantly more frequent at higher income levels (P = 0.002), as was attending physician presence at M&M conferences (70% in high-income countries versus 43% in lower-middle-income countries). There were also significant differences in the structure, quality, and follow-up of M&M conferences in lower versus higher income countries. Sixty-three percent of respondents reported observing some kind of positive change at their institution due to M&M conferences. The survey also suggested significantly higher utilization of autopsy (P < 0.001) and electronic trauma registries (P = 0.01) at higher income levels. CONCLUSIONS: This survey demonstrated an encouraging pattern of widespread adoption of trauma QI programs in several countries in North and South America. However, there continue to be significant disparities in the structure and function of trauma QI efforts in low- and middle-income countries in the Americas. There are several potential areas for development and improvement of trauma care systems, including standardization of case selection and follow-up for M&M conferences and increased use of medical literature to improve evidence-based care. PMID- 29180185 TI - ADAM-17 expression is enhanced by FoxM1 and is a poor prognostic sign in gastric carcinoma. AB - BACKGROUND: The ADAMs proteases are a multifunctional family of proteins, many of which participate in the pathogenesis of cancers. The expression and regulation of ADAMs has not yet been fully examined in gastric cancer. MATERIALS AND METHODS: Using reverse transcription-PCR, messenger RNA expression of ADAM-9, ADAM-10, ADAM-11, ADAM-12, ADAM-15, ADAM-17, ADAM-28, and ADAM-33 was detected in gastric cancer. ADAM-10, ADAM-17, ADAM-28, and FoxM1 expression in gastric cancer was detected by Western blot and immunohistochemistry. The correlation between ADAM-17 and FoxM1 was analyzed in vivo and in vitro. RESULTS: The messenger RNA levels of ADAM-9, ADAM-10, ADAM-15, ADAM-17, ADAM-28, and ADAM-33 were increased in tumor tissues compared with adjacent normal tissue, especially ADAM-10, ADAM 17, and ADAM-28. FoxM1 expression correlated significantly with ADAM-17 expression. FoxM1 regulates ADAM-17 expression in vivo and in vitro, which in turn influences proliferation and tumor growth of gastric cancer cells. Furthermore, Cox regression analysis revealed that FoxM1 and ADAM-17 are independent prognostic factors for patients with gastric cancer. CONCLUSIONS: These results indicate that overexpression of ADAMs may contribute to gastric cancer progression and that ADAM-17 is a downstream target of FoxM1. Overall, the present study highlights the potential for FoxM1 and ADAMs as potential therapeutic targets for patients with gastric carcinoma. PMID- 29180186 TI - Laparoscopic versus open liver resection for colorectal liver metastases: a systematic review. AB - BACKGROUND: Laparoscopic liver resection (LLR) has been proposed as a safe and feasible treatment option for colorectal liver metastasis (CRLM). However, the short-term and oncologic outcomes of LLR versus open liver resection (OLR) for CRLM have not been adequately assessed. Thus, we herein provide an updated systematic review comparing short-term and oncologic outcomes of CRLM patients undergoing LLR versus OLR. METHODS: A systematic literature search was performed in the Pubmed, Embase, and Cochrane Library databases (until November 2, 2016) with a limitation to the publications in English. Quality assessment was performed based on the modification of the Newcastle-Ottawa Scale. Dichotomous data were calculated by odds ratio (OR), and continuous data were calculated by weighted mean difference (WMD) with 95% confidence intervals (CIs). RESULTS: A total of 28 studies enrolling 4591 patients with CRLM were included. With respect to short-term outcomes, patients in LLR group showed significantly reduced blood loss (WMD: -143.64; 95% CI: -180.56 to -106.73; I2 = 86%; P < 0.001), lower operative transfusion requirement (OR: 0.40; 95% CI: 0.30-0.53; I2 = 0%; P < 0.001), shorter hospital stay (WMD: -2.47; 95% CI: -2.99 to -1.94; I2 = 82%; P < 0.001), reduced overall postoperative morbidity (OR: 0.53; 95% CI: 0.42-0.66; I2 = 38%; P < 0.001) and reduced severe morbidity (OR: 0.44; 95% CI: 0.32-0.60; I2 = 35%; P < 0.001). Regarding oncologic outcomes, there were no significant differences between the two surgical procedures in recurrence and 1-, 3-, and 5 overall survival and disease-free survival except for slightly higher R0 resection rate in LLR group was slightly higher than that of OLR group (OR: 1.43; 95% CI: 1.03-1.97; I2 = 37%; P = 0.03). CONCLUSIONS: LLR should be the standard approach for selected patients with CRLM, and further research should focus on determining which patients would benefit most from LLR. PMID- 29180187 TI - Glutamine reduces myocardial cell apoptosis in a rat model of sepsis by promoting expression of heat shock protein 90. AB - BACKGROUND: Myocardial cell injury and cardiac myocyte apoptosis are associated with sepsis. Glutamine (Gln) has been reported to repair myocardial cell injury. The aim of this study was to explore the role of Gln on cardiac myocytes in a cecal ligation and puncture (CLP) model of sepsis in Wistar rats. MATERIALS AND METHODS: Following induction of sepsis in a CLP rat model, viral encoding heat shock protein 90 (Hsp90) gene and Hsp90dsDNA were designed to express and knockdown Hsp90, respectively. Rat cardiac tissues were examined histologically, and apoptosis was detected by terminal deoxynucleotidyl transferase dUTP nick end labeling staining. The expression of B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein, Hsp90, p53 upregulated modulator of apoptosis, and p53 was measured by western blotting and real-time polymerase chain reaction. Caspase-3, caspase-8, and caspase-9 were detected by enzyme-linked immunosorbent assay. RESULTS: Rat cardiac myocyte damage induced by CLP was reduced by Gln treatment and Hsp90 overexpression, and these changes were reversed by Hsp90 knockdown. Bcl-2 expression, Bcl-2-associated X protein, p53, p53 upregulated modulator of apoptosis, caspase-8, caspase-9, and caspase-3 activities were significantly upregulated in the CLP model, which were reduced by Gln treatment and Hsp90 overexpression. CONCLUSIONS: Gln reduced apoptosis of cardiac myocytes in a rat model of sepsis, by promoting Hsp90 expression. Further studies are needed to determine the possible therapeutic action of Gln in sepsis in human tissue. PMID- 29180188 TI - Statewide assessment of surgical outcomes and the acute care surgery model. AB - BACKGROUND: The acute care surgery (ACS) model has been widely implemented with single institution studies demonstrating improved outcomes. Recent multicenter studies have raised questions about the economics and efficacy of ACS. This study compares traditional and ACS outcomes across an entire state. METHODS: A retrospective review of Virginia's Health Information administrative database was completed. Adults admitted with appendicitis or cholecystitis between 2008 and 2014 were included. Hospital administration was contacted to determine surgical model. To compare patient characteristics, t-test and chi-square analyses were used. Total charges and length of stay (LOS) differences between ACS and traditional were examined using generalized linear models, whereas logistic regression was used for the presence of complications and 30-day mortality. RESULTS: Overall, the ACS model showed an increased proportion of uninsured patients with a higher rate of comorbidities. In the appendicitis subgroup, (n = 22,011; ACS n = 1993), ACS patients had higher total charges ($30,060 versus $28,460, P = 0.013), longer LOS (3.31 versus 2.92 d, P < 0.001), and higher chance of complications (odds ratio [OR] = 1.2, P = 0.016) and mortality (OR = 2.4, P = 0.029). After adjustment for comorbidities and insurance, mortality was no longer significantly different. In the cholecystitis group (n = 6936; ACS n = 777), ACS patients had a longer LOS (4.55 versus 4.13 d; P = 0.009) without significant differences in mortality, complications, or cost. There were no significant differences after adjustment for patient characteristics. CONCLUSIONS: ACS patients in Virginia have a higher rate of medical comorbidities and uninsured status, with slightly worse outcomes than the traditional model for appendicitis. Further studies to determine which patients benefit the most from ACS are warranted. PMID- 29180189 TI - Impact of triage guidelines on prehospital triage: comparison of guidelines with a statistical model. AB - BACKGROUND: The American College of Surgeons developed the National Field Triage Decision Scheme (NFTDS) that has been adapted by many trauma centers in the nation, but quantitative evidence of its efficacy is unclear. We compare the NFTDS and state of Ohio guidelines to the "observed" rates and with rates derived using a statistical model. METHODS: We used 4757 trauma records from 2008-2012 available from the state and calculated undertriage (UT) and overtriage (OT) rates. We then simulated the NFTDS and the state guidelines for those years and estimated the corresponding UT and OT rates. We finally compared these rates with those derived from a multivariate logistic regression model. RESULTS: For the state data, both NFTDS and state guidelines produced lower UT rate (~9%) compared with the observed rate (~17%), whereas the OT rates were higher (>85%) than the observed rates (~54%). The statistical model identified novel factors that were not directly available in the NFTDS; change in responsiveness (odds ratio [OR] = 1.924) and complaint in body (OR = 3.140), back (OR = 1.890), chest (OR = 3.191), head (OR = 3.878), and abdomen (OR = 2.966). Although the statistical model performed similar to observed rates, it performed considerably better than NFTDS (UT = 1.93% versus 9.03%; OT = 66.42% versus 87.52%) and state guidelines (UT = 2.18% versus 8.72%; OT = 64.09% versus 86.52%). CONCLUSIONS: The current NFTDS and state's triage guidelines do not appear to achieve the ACS recommendation of <5% UT and <35% OT rates in the state of Ohio. Inclusion of region-specific factors may help enhance the current NFTDS guidelines and aid in the first impression or judgment of the Emergency Medical Services personnel to improve trauma care and reduce cost. PMID- 29180190 TI - Patterns of sural nerve innervation of the sural artery with implication for reconstructive surgery. AB - BACKGROUND: Most of the literature concerning the neurocutaneous flap is related to its anatomic investigation and clinical application, and the more in-depth physiological problem such as whether the cutaneous nerve contains sympathetic fibers that innervate its accompanying vessels has never been explored. MATERIALS AND METHODS: Dissection was first performed on three rabbits. In another 22 rabbits, two rabbits undergoing no surgery were used as the normal control group. In the remaining 20 rabbits, the 40 sides of hind limbs were divided into a nerve severance group, where the sural nerve was transected at its origin after creation of the proximally based sural neurocutaneous flap, and a nerve preservation group, in which the continuation of the sural nerve was preserved. The sural neurovascular bundles at four time points were harvested for immunohistochemical and Western blotting analyses of the expression of tyrosine hydroxylase (TH). An infrared thermal imager was used for measurement of the average flap temperature within the first 24 h. RESULTS: The sural neurovascular bundle entered the skin at 4.5 +/- 1.2 cm above the lateral malleolus. The TH in the sural nerve and tunica adventitia of the sural artery showed a synchronized abated expression in the nerve severance group. The TH expression showed no decline in the nerve preservation group. The average flap temperature in the nerve severance group was higher than that in the nerve preservation group starting from 2 h after flap harvest (P = 0.05). CONCLUSIONS: The cutaneous nerve has meted out sympathetic fibers to the accompanying artery, regulating its vascular tone. PMID- 29180191 TI - Suture thread check test for detection of surgical site contamination: a prospective study. AB - BACKGROUND: Surgical site infection (SSI) is a common complication of surgical procedures. AIM: Our study aimed at investigating a new method based on assessment of suture thread colonization to identify patients developing an SSI. MATERIALS AND METHODS: We prospectively enrolled 119 patients undergoing elective surgery. For each patient, a synthetic absorbable thread in Lactomer 9-1 (Polisorb Gauge 2) inserted in the surgical site at the end of surgery was sent to the microbiology laboratory after 48 h to assess colonization of its inner tract. RESULTS: Forty (33.6% of cases) patients had a colonized thread. Antibiotic prophylaxis was administered to 66 of 79 patients who did not display a colonized thread and to 20 of the 40 patients with a colonized thread (83.5% versus 50%, respectively, P = 0.0002). An SSI was observed only in patients with a colonized thread (10% versus 0, P = 0.02). The microorganisms identified in colonized threads were the same identified in SSIs. CONCLUSIONS: Since an SSI was found only in patients with colonized threads, the method described here may be valuable for identifying patients developing an SSI. Moreover, the method can also be useful for targeting efficient antibiotic therapy to the culprit microorganisms. PMID- 29180192 TI - Reduced serum cholinesterase activity indicates splenic modulation of the sterile inflammation. AB - BACKGROUND: Sterile inflammation is an immediate and well-coordinated immune response to surgical injury. The cholinergic system plays a pivotal role in the inflammatory response. Induced inflammation stimulates the vagus nerve, which in turn activates anti-inflammatory nonneuronal processes. Serum cholinesterase (butyrylcholinesterase [BChE]) is an enzyme that hydrolyzes acetylcholine. Measuring the activity of the BChE in blood might indicate the level of the nonneuronal cholinergic activity. The spleen is a major organ of the immune system playing an important role during inflammation. A functional connection of the neuroimmune reflex has thus far been described only in experimental settings. MATERIALS AND METHODS: In 48 patients receiving major pancreatic surgery, BChE activity was measured by applying point-of-care-testing, in addition to standard laboratory tests. RESULTS: The BChE activity decreased in patients receiving surgery. This reduction emerged much earlier than changes in C-reactive protein concentration, an inflammatory biomarker broadly used in the clinical environment. A milder reduction in the BChE activity was observed in patients subjected to surgery with splenectomy than in those with a preserved spleen. CONCLUSIONS: The use of the point-of-care-testing system for quick bedside diagnostics and the rapid effects of inflammation on BChE levels provide a method and a marker to facilitate the early detection of systemic inflammation. Furthermore, this study provides evidence that the experimentally documented neuroimmune interaction is part of the physiological response to surgery-induced sterile inflammation. Splenic function plays an essential role in modulating the cholinergic anti-inflammatory response. PMID- 29180193 TI - Defining payments associated with the treatment of colorectal cancer. AB - BACKGROUND: While bundled payments aim to reduce variations in health care spending across the continuum of care, data reporting on variations in payments for privately insured patients undergoing treatment for colon cancer (CC) are lacking. The current study sought to characterize variations in payments received for the treatment of CC using a cohort of commercially insured patients. METHODS: Patients who underwent a colectomy for CC were identified using the MarketScan Database for 2010-2014. Multivariable regression analysis was used to calculate and compare risk-adjusted payments between patients. RESULTS: A total of 18,337 patients were identified who met inclusion criteria. The median risk-adjusted payment for surgery was $26,408 (IQR: $19,193-$38,037) ranging from $19,762 (IQR: $15,595-$25,636) among patients in the lowest quartile of payments to $33,809 (IQR: $24,783-$48,254) for patients in the highest (+?71.1%). The median risk adjusted payment for chemotherapy was $70,090 (IQR: $57,813-$83,216); compared with patients in the lowest quartile of payments, payments associated with chemotherapy were 40.4% higher among patients in the highest quartile of payments (Q1 versus Q4: $56,827 [IQR: 49,173-65,353] versus $79,801 [IQR: 67,270-90,999]). When stratified by treatment type, patients in the highest two quartiles of risk adjusted payments accounted for a total of 58.5% of all payments, whereas patients in the lower two quartiles of risk-adjusted payments accounted for only 41.5% of all payments. A younger patient age, increasing patient comorbidity and undergoing an open operation were associated with higher overall payments. CONCLUSIONS: Wide variations in payments exist for the treatment for colon cancer. Episode-based bundle payments for surgery and chemotherapy may differentially impact reimbursement for CC. PMID- 29180194 TI - Perioperative complications of emergent and elective procedures in psychiatric patients. AB - BACKGROUND: Patients with psychiatric disorders have an increased risk for morbidity and mortality from other medical conditions. METHODS: Medical records of all the patients undergoing appendectomy (n = 2594) and laparoscopic cholecystectomy (n = 2874) from 2009 to 2014 in one hospital were reviewed. For each patient with a documented psychiatric disorder undergoing surgery, four controls were matched. RESULTS: The final sample of patients undergoing appendectomy included 96 patients, whereas those undergoing laparoscopic cholecystectomy included 260 patients. In the emergent scenario, psychiatric patients had longer time from symptom appearance to admission, longer hospitalization duration, and increased rate and severity of postoperative complications. In the elective scenario, psychiatric patients were shown to have more postoperative respiratory complications. CONCLUSIONS: Our results, together with the high prevalence of psychiatric disorders in the population, underscore the importance of screening for psychiatric disorders and their proper documentation in surgical patients. PMID- 29180195 TI - Sutures versus new cyanoacrylates in prosthetic abdominal wall repair: a preclinical long-term study. AB - BACKGROUND: As an alternative to sutures, meshes used for hernia repair can be fixed using cyanoacrylate-based adhesives. Attempts to improve these adhesives include alkyl-chain lengthening to reduce their toxicity. This preclinical study compares the long-term behavior of cyanoacrylates of different chain lengths already used in hernia repair and new ones for this application. MATERIALS AND METHODS: Partial abdominal wall defects were repaired using a Surgipro mesh in 18 New Zealand White rabbits, and groups were established according to the mesh fixation method: sutures (control), Glubran 2 (n-butyl), Ifabond (n-hexyl), and the new adhesives SafetySeal (n-butyl), and Evobond (n-octyl). Six months after surgery, recovered implants were examined to assess adhesive degradation, host tissue reaction, and biomechanical strength. RESULTS: All the cyanoacrylate groups showed good host tissue incorporation in the meshes. Macrophage responses to Glubran and Ifabond were quantitatively greater compared with sutures. Cell damage caused by the adhesives was similar, and only Glubran induced significantly more damage than sutures. Significantly lower collagen 1/3 messenger RNA expression was induced by Ifabond than the remaining fixation materials. No differences were observed in collagen expression except slightly reduced collagen I deposition in Glubran/Ifabond and collagen III deposition in the suture group. Mechanical strengths failed to vary between the suture and cyanoacrylate groups. CONCLUSIONS: All cyanoacrylates showed good long-term behavior and tolerance irrespective of their long or intermediate chain length. Cyanoacrylate residues persisted at 6 mo, indicating their incomplete degradation. Biomechanical strengths were similar both for the adhesives and sutures. PMID- 29180196 TI - Laparotomy causes loss of peritoneal mesothelium prevented by humidified CO2 insufflation in rats. AB - INTRODUCTION: Avoiding tissue desiccation is a common recommendation to reduce postoperative complications following open abdominal surgery, although difficult to achieve delicately without damaging the peritoneal mesothelium. Insufflation of humidified-warm CO2 into the abdomen during open abdominal surgery is proposed as an invisible, effortless way to prevent desiccation. We hypothesized that desiccation during open abdominal surgery would cause loss of peritoneal mesothelium that would be prevented by insufflation of humidified-warm CO2. METHODS: Nine Wistar rats were assigned to 1 h of anesthesia only, laparotomy only, or laparotomy with insufflation of humidified-warm CO2. Twelve hours after treatment, rats were euthanized and tissue samples were excised. Scanning electron microscopy (SEM) and light microscopy (LM) images of visceral and parietal peritoneum were scored by two independent, blinded examiners for loss of mesothelium and other indications of inflammation, including measurement of apoptosis by detection of DNA cleavage. RESULTS: Loss of peritoneal mesothelium was found in peritoneum exposed to laparotomy only (SEM: P = 0.002; LM: P = 0.01), and mesothelial loss was reduced by humidified-warm CO2 (SEM: P < 0.001; LM P = 0.004). Similarly, DNA cleavage was significantly higher on the peritoneal surface following laparotomy only, compared with anesthesia only (P = 0.0055) and laparotomy with humidified-warm CO2 insufflation (P = 0.0003). CONCLUSIONS: In a rat model, exposing the peritoneal mesothelial to conditions that replicate minimum recommended air flow within an operating room causes inadvertent loss of mesothelium and signs of inflammation that can be prevented by insufflating humidified-warm CO2 into the open abdominal cavity. PMID- 29180197 TI - TSG-6 is highly expressed in human abdominal aortic aneurysms. AB - BACKGROUND: The formation of abdominal aortic aneurysms (AAA) is characterized by a dominance of proinflammatory forces that result in smooth muscle cell apoptosis, extracellular matrix degradation, and progressive diameter expansion. Additional defects in the antiinflammatory response may also play a role but have yet to be fully characterized. TSG-6 (TNF-stimulated gene-6) is a potent antiinflammatory protein involved in extracellular matrix stabilization and cell migration active in many pathological conditions. Here, we describe its role in AAA formation. METHODS: Blood and/or aortic tissue samples were collected from organ donors, subjects undergoing elective AAA screening, and open surgical AAA repair. Aortic specimens collected were preserved for IHC or immediately assayed after tissue homogenization. Protein concentrations in tissue and plasma were assayed by ELISA. All immune cell populations were assayed using FACS. In vitro, macrophage polarization from monocytes was performed with young, healthy donor PBMCs. RESULTS: TSG-6 was found to be abnormally elevated in both the plasma and aortic wall of patients with AAA compared with healthy and risk-factor matched non-AAA donors. We observed the highest tissue concentration of TSG-6 in the less diseased proximal and distal shoulders compared with the central aspect of the aneurysm. IHC localized most TSG-6 to the tunica media with minor expression in the tunica adventitia of the aortic wall. Higher concentrations of both M1 and M2 macrophages where also observed, however M1/M2 ratios were unchanged from healthy controls. We observed no difference in M1/M2 ratios in the peripheral blood of risk-factor matched non-AAA and AAA patients. Interesting, TSG-6 inhibited the polarization of the antiinflammatory M2 phenotype in vitro. CONCLUSIONS: AAA formation results from an imbalance of inflammatory forces causing aortic wall infiltration of mononuclear cells leading to the vessel breakdown. In the AAA condition, we report an elevation of TSG-6 expression in both the aortic wall and the peripheral circulation. PMID- 29180198 TI - Surgical tray optimization as a simple means to decrease perioperative costs. AB - BACKGROUND: Health care spending in the US remains excessively high. Aside from complicated, large-scale efforts at health care cost reduction, there are still relatively simple ways in which individual hospitals can cut unnecessary costs from everyday operations. Inspired by recent publications, our group sought to decrease the costs associated with surgical instrument processing at a large, multihospital academic center. METHODS: This was a single-site observational study conducted at a large academic medical center. At the study start, all attending surgeons within the section of pediatric surgery agreed to standardize the pediatric surgery trays and to eliminate instruments that were deemed unnecessary from each tray. A multidisciplinary start-up meeting was held, and this meeting included stakeholders from central sterile processing, operating room nursing, scrub technicians, and materials management along with all five pediatric surgeons. Each tray was addressed individually. Instruments were eliminated from trays only if there was unanimous agreement among all the surgeons in the group. If no instruments in a given surgical tray were deemed necessary, the entire tray was eliminated from sterile processing rotation. Feedback questionnaires were drafted by the multidisciplinary team that participated in the start-up meeting. Surgeons were allowed to request for certain instruments to be placed back into the trays at any time, and the questionnaires also allowed for free-hand comments. Surgical kit preparation time was obtained from the institutional barcode scanning system. The cost per second of sterile processing labor was calculated using regional median salary for sterile processing technicians in the state of Connecticut. Using the pediatric surgery section as the model unit, this method was then applied to pediatric urology, neurosurgery, spine surgery, and orthopedics. RESULTS: The pediatric surgery section eliminated an average of 59.5% of instruments per tray, resulting in an overall reduction of 1826 (39.5%) instruments from rotation, 45,856 fewer instruments processed per year, and nine trays eliminated completely from regular rotation. Processing time for six commonly used trays was reduced by an average of 28.7%. The urology section eliminated 18 trays from regular rotation and 179 (10.1%) instruments in total. Pediatric orthopedics, neurosurgery, and spine sections eliminated 708 (17.1%), 560 (92.7%), and 31 (32.2%) instruments, respectively, resulting in approximately 18,804 fewer instruments processed per year. Among all five surgical sections, annual instrument cost avoidance after tray optimization was estimated at $53,193 to $531,929 using average instrument life spans ranging from 1-10 y. Negative feedback and requests for instrument replacement were both minimal on feedback questionnaires. CONCLUSIONS: Surgical tray optimization represents a relatively simple microsystem improvement that could result in significant hospital cost reduction. Although difficult to quantify, other gains from surgical kit optimization include decreased weight per tray, decreased materials cost, and decreased labor required to count, decontaminate, and pack surgical trays. PMID- 29180199 TI - Dose-dependent effect of parathyroid hormone on fracture healing and bone formation in mice. AB - BACKGROUND: Parathyroid hormone (PTH) is the only clinically approved osteoanabolic drug for osteoporosis treatment. However, PTH is not established for the treatment of fracture healing, and doses of PTH diverge significantly between different studies. We hypothesized that the effect of PTH on promoting fracture healing and bone formation is dose dependent. MATERIALS AND METHODS: In vivo, mice were treated with PTH (10, 40, and 200 MUg/kg) in a closed femoral fracture model. Fracture healing was analyzed after 4 weeks. The fourth lumbar vertebra was analyzed to assess systemic effects. In addition, osteoblasts from calvaria of mice were treated in vitro with PTH doses of 10-5-50 nM, and their differentiation was analyzed after 26 days. RESULTS: In vivo, PTH dose dependently stimulated bone formation in the fracture callus and the vertebral body. However, PTH treatment did not increase biomechanical stiffness of the fractured femora in a dose-dependent manner. The increased bone formation in the 200 MUg/kg group was associated with a depletion of osteoclasts, indicating diminished bone remodeling. Of interest, in vitro, we observed diminished mineralization with the highest doses of PTH in osteoblast cultures. CONCLUSIONS: PTH dose-dependently stimulates bone formation in vivo. However, during fracture healing, this did not result in a dose-dependent increase of the mechanical stiffness of the fracture callus. Taken together, our in vivo and in vitro data indicate that the dose-dependent effects of PTH during fracture healing are based on the actions on multiple cell types, thereby influencing not only bone formation but also osteoclastic callus remodeling. PMID- 29180200 TI - Indicators of breast cancer in patients undergoing microdochectomy for a pathological nipple discharge in a middle-income country. AB - BACKGROUND: The management of a pathological nipple discharge often involves surgery for the exclusion of a malignant etiology. This study aimed to determine the prevalence of cancer in patients who had microdochectomy for pathological nipple discharge in a population in South Africa and to evaluate patients' demographics and clinical characteristics as indicators of underlying cancer and make recommendations for their management in resource-limited settings. MATERIALS AND METHODS: Clinical, radiological, and histological data from 153 patients who underwent a microdochectomy for a pathological nipple discharge at two South African breast clinics was collected. RESULTS: Invasive or in situ cancer was found in 12 patients (7.84%), and in all patients, cancer was associated with a bloody nipple discharge. Bloody discharge had a sensitivity of 100% in indicating cancer, specificity of 55.32%, positive predictive value of 16%, and negative predictive value of 100%. Patients with breast cancer were also more likely to be aged 55 y or older (P = 0.04). Preoperative mammogram and ultrasound were poor in detecting cancer (0/12). CONCLUSIONS: In our population, a bloody discharge in women aged 55 years or older should mandate a microdochectomy, with selective surgery for younger women and those with nonbloody discharges. Thorough clinical examination to determine the true color and nature of the discharge is vital in the initial assessment of these patients. Preoperative radiology is not helpful in determining the presence of cancer (in an isolated pathological nipple discharge), and microdochectomy still remains the gold standard in diagnosing cancer in these patients. PMID- 29180201 TI - Laparoscopic repair of perforated peptic ulcer: simple closure versus omentopexy. AB - BACKGROUND: This report presents our experience with laparoscopic repair performed in 118 consecutive patients diagnosed with a perforated peptic ulcer (PPU). We compared the surgical outcome of simple closure with modified Cellan Jones omentopexy and report the safety and benefit of simple closure. METHODS: From January 2010 to December 2014, 118 patients with PPU underwent laparoscopic repair with simple closure (n = 27) or omentopexy (n = 91). Charts were retrospectively reviewed for demographic characteristics and outcome. The data were compared by Fisher's exact test, Mann-Whitney U test, Pearson's chi-square test, and the Kruskal-Wallis test. The results were considered statistically significant if P < 0.05. RESULTS: No patients died, whereas three incurred leakage. After matching, the simple closure and omentopexy groups had similarity in sex, systolic blood pressure, pulse rate, respiratory rate, Boey score, Charlson comorbidity index, Mannheim peritonitis index, and leakage. There were statistically significant differences in age, length of hospital stay, perforated size, and operating time. Comparison of the operating time in the <=4.0 mm and 5.0-12 mm groups revealed that the simple closure took less time than omentopexy in both groups (<=4.0 mm, 76 versus 133 minutes, P < 0.0001; 5.0-12 mm, 97 versus 139.5 minutes; P = 0.006). CONCLUSIONS: Compared to the omentopexy, laparoscopic simple closure is a safe procedure and shortens the operating time. PMID- 29180202 TI - Resident and fellow participation in Thyroid and Parathyroid surgery: an ACS NSQIP clinical outcomes analysis. AB - BACKGROUND: The effect of decreased overall hours of training in surgical specialties is still being examined. Of particular interest is the safety of patients undergoing surgeries with trainee surgeons. The aim of this study was to identify if there were significant differences in outcomes of patients undergoing commonly performed thyroid and parathyroid surgeries when trainees were involved. MATERIALS AND METHODS: Postoperative complication rates, length of stay (LOS), and total operation time (OT) data were gathered from the American College of Surgeons National Surgical Quality Improvement Project database. The cases were identified by CPT code and were divided based on the training level of the participating resident surgeon: Junior (postgraduate year [PGY] 1-2), senior (PGY 3-5), fellow (PGY >5), as well as an attending-only group where no resident was present. We compared the clinical outcomes, LOS, and OT in each trainee group to the attending-only group as the reference. RESULTS: A total of 84,711 cases were identified of which 45.33% involved trainee participation. Odds ratios (ORs) and 95% confidence interval for overall, neurologic, and bleeding complications were calculated. No difference in the odds of overall patient complications or neurologic complications was observed. A decrease in the odds of bleedings complications when a junior or senior trainee was present was observed. Overall complications in operations including a junior trainee (PGY 1-2) had an OR of 1.04 (0.85, 1.29), a senior trainee (PGY 3-5) had an OR of 1.00 (0.89, 1.13), and a fellow had an OR of 0.98 (0.74, 1.31). Mean OT was found to be significantly different between attending only and junior and senior trainees. There was no significant difference in OT between fellows and attending only. LOS did not meaningfully differ across groups. CONCLUSIONS: In three commonly performed thyroid and parathyroid operations, there is not an increased overall or neurologic complication odds when a surgical trainee is involved; there are decreased odds of a bleeding complication. PMID- 29180203 TI - CEACAM1 is associated with recurrence after hepatectomy for colorectal liver metastasis. AB - BACKGROUND: Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is re-expressed at the invasion front of colorectal cancer. CEACAM1 expression at metastatic sites remains to be investigated. The current study aims to clarify the association between CEACAM1 expression and recurrence after hepatectomy of colorectal liver metastasis and to address whether CEACAM1 induces tumor initiating properties needed for growth at metastatic sites. METHODS: Immunohistochemical analyses for CEACAM1 were performed in 67 patients with liver metastasis of colorectal cancer who had undergone curative hepatectomy. The risk factors for postoperative recurrence were calculated based on a CEACAM1 cytoplasmic domain isoform at the primary tumor invasion front. To investigate the effects of CEACAM1 cytoplasmic isoforms on HT29 and HCT116 colorectal cancer cells, Western blotting for CD44 and CD133, flow cytometry for ALDH1 activity, and soft-agar colony formation assay were performed. RESULTS: CEACAM1 long (CEACAM1-L) and short (CEACAM1-S) cytoplasmic domain isoforms are strongly expressed on cancer cells in the liver metastases. Enhanced CEACAM1-S expression in the state of CEACAM1-L dominance at the primary tumor invasion front was an independent factor for colorectal cancer recurrence after curative hepatectomy. CEACAM1-4S-transfected HT29 and HCT116 cells had significantly higher CD44 expression and ALDH1 activity and increased the growth in anchorage-independent condition. CONCLUSIONS: High expression of CEACAM1-S at the primary lesion invasion front is associated with recurrence and prognosis of patients with colorectal liver metastasis after curative hepatectomy. The expression of CEACAM1 4S enhances the tumor-initiating property of colorectal cancer cells. PMID- 29180204 TI - Hyperoxygenated hydrogen-rich solution suppresses shock- and resuscitation induced liver injury. AB - BACKGROUND: It is not known whether simultaneous delivery of hydrogen and oxygen can reduce injury caused by hemorrhagic shock and resuscitation (HSR). This study investigated the therapeutic potential of hyperoxygenated hydrogen-rich solution (HHOS), a combined hydrogen/oxygen carrier, in a rat model of HSR-induced liver injury. MATERIALS AND METHODS: Rats (n = 60) were randomly divided into 5 groups (n = 6 per group at each time point). One group underwent sham operation, and the others were subjected to severe hemorrhagic shock and then treated with lactated Ringer's solution (LRS), hydrogen-rich solution, hyperoxygenated solution, or HHOS. At 2 and 6 h after resuscitation, blood samples (n = 6) were collected from the femoral artery and serum concentrations of alanine aminotransferase and aspartate aminotransferase (AST) were measured. Rats were then sacrificed, and histopathological changes in the liver were evaluated by quantifying the percentage of apoptotic cells by caspase-3 immunohistochemistry and terminal deoxynucleotidyl transferase dUTP nick-end labeling. Inflammation was assessed by assessing malondialdehyde content and tumor necrosis factor-alpha, and interleukin (IL)-6 expression. RESULTS: Compared to lactated Ringer's solution, hydrogen-rich solution, or hyperoxygenated solution groups, serum AST and alanine aminotransferase levels and IL-6, tumor necrosis factor-alpha, and malondialdehyde expression in liver tissue were decreased by HHOS treatment. The number of caspase-3- and terminal deoxynucleotidyl transferase dUTP nick end labeling-positive cells was decreased (P < 0.05) by HHOS treatment, 2 and 6 h after resuscitation. CONCLUSIONS: HHOS has protective effects against liver injury in a rat model of HSR. PMID- 29180205 TI - Effect of transfer status on outcomes for necrotizing soft tissue infections. AB - BACKGROUND: Whether patients with necrotizing soft tissue infections (NSTI) who presented to under-resourced hospitals are best served by immediate debridement or expedited transfer is unknown. We examined whether interhospital transfer status impacts outcomes of patients requiring emergency debridement for NSTI. METHODS AND MATERIALS: We conducted a retrospective review studying patients with an operative diagnosis of necrotizing fasciitis, Fournier's gangrene, or gas gangrene in the 2010-2015 American College of Surgeons National Surgical Quality Improvement Program Participant Use Data Files. Multivariable regression analyses determined if transfer status independently predicted 30-d mortality, major morbidity, minor morbidity, and length of stay. RESULTS: Among 1801 patients, 1243 (69.0%) were in the non-transfer group and 558 (31.0%) were in the transfer group. The transfer group experienced higher rates of 30-d mortality (14.5% versus 13.0%) and major morbidity (64.5% versus 60.1%) than the non-transfer group, which were not significant after risk adjustment (adjusted odds ratio [95% confidence interval]: 0.87 [0.62-1.22] and 1.00 [0.79-1.27], respectively). The transferred group experienced a longer median length of postoperative hospitalization (14 d [interquartile range 8-24] versus 11 d [6-20]), which maintained statistical significance after adjustment for other factors (adjusted beta coefficient [95% confidence interval]: 1.92 [0.48-3.37]; P = 0.009). CONCLUSIONS: Our results suggest that interhospital transfer status is not an independent risk factor for mortality or morbidity after surgical management of NSTI. Although expedient debridement remains a basic tenet of NSTI management, our findings provide some reassurance that transfer before initial debridement will not significantly jeopardize patient outcomes should such transfer be deemed necessary. PMID- 29180206 TI - Ropivacaine wound infiltration: a fast-track approach in patients undergoing thoracotomy surgery. AB - BACKGROUND: Postoperative pain impairs enhanced recovery in patients after various surgeries. Local use of ropivacaine has become an effective strategy for postoperative pain management. The aim of this study was to assess the effectiveness and safety of wound infiltration with ropivacaine for postoperative analgesia as a fast-track approach in patients undergoing thoracotomy surgery. MATERIALS AND METHODS: Forty adult patients with esophageal cancer scheduled for selective thoracotomy surgery were enrolled in this double-blind, randomized, controlled study. Patients were randomized (1:1) to receive ropivacaine or placebo wound infiltration before incision closure. Numerical rating score (NRS), postoperative analgesics consumption, length of hospital stay, time to anal exsufflation, defecation, ambulation, and patient satisfaction scores were recorded. Side effects including allergic reaction, nausea, vomiting, wound infection, and pneumonia were also assessed. RESULTS: NRS was significantly decreased in the ropivacaine group with less consumption of postsurgery analgesics. The ropivacaine group also showed shorter postoperative hospital stays, earlier anal exsufflation and ambulation, and higher patient satisfaction scores. However, there were no significant differences between the two groups regarding time of defecation. No allergic reactions occurred in either group. The incidences of nausea, vomiting, wound infection, and pneumonia were similar. CONCLUSIONS: The present study showed that ropivacaine wound infiltration could be a safe and effective fast-track approach for patients undergoing thoracotomy surgery. PMID- 29180207 TI - Residents' response to bleeding during a simulated robotic surgery task. AB - BACKGROUND: The aim of this study was to assess performance measurement validity of our newly developed robotic surgery task trainer. We hypothesized that residents would exhibit wide variations in their intercohort performance as well as a measurable difference compared to surgeons in fellowship training. MATERIALS AND METHODS: Our laboratory synthesized a model of a pelvic tumor that simulates unexpected bleeding. Surgical residents and fellows of varying specialties completed a demographic survey and were allowed 20 minutes to resect the tumor using the da Vinci robot and achieve hemostasis. At a standardized event in the simulation, venous bleeding began, and participants attempted hemostasis using suture ligation. A motion tracking system, using electromagnetic sensors, recorded participants' hand movements. A postparticipation Likert scale survey evaluated participants' assessment of the model's realism and usefulness. RESULTS: Three of the seven residents (postgraduate year 2-5), and the fellow successfully resected the tumor in the allotted time. Residents showed high variability in performance and blood loss (125-700 mL) both within their cohort and compared to the fellow (150 mL blood). All participants rated the model as having high realism and utility for trainees. CONCLUSIONS: The results support that our bleeding pelvic tumor simulator has the ability to discriminate resident performance in robotic surgery. The combination of motion, decision-making, and blood loss metrics offers a multilevel performance assessment, analyzing both technical and decision-making abilities. PMID- 29180208 TI - MZB1 in borderline resectable pancreatic cancer resected after neoadjuvant chemoradiotherapy. AB - BACKGROUND: A high accumulation of CD8+ tumor-infiltrating lymphocytes (TILs) induced by neoadjuvant chemoradiotherapy (NACRT) is associated with a favorable prognosis in patients with pancreatic ductal adenocarcinoma (PDAC). However, the correlation between a high accumulation of CD8+ TILs and a favorable prognosis has yet to be fully clarified. The aim of this study was to determine predictive markers of a high accumulation of CD8+ TILs, with a favorable prognosis, using proteomic analysis. MATERIALS AND METHODS: We studied 72 resected borderline resectable PDAC patients treated with NACRT between April 2009 and March 2014. Three matched pairs of high CD8+ TIL patients with a favorable prognosis and low CD8+ TIL patients with a poor prognosis were selected. Shotgun proteomics of the stroma and cancerous lesion was performed using formalin-fixed, paraffin-embedded tissue. Validation of the identified proteins was performed using immunohistochemical staining. Relationships between the identified proteins and TILs and clinical outcomes were assessed. RESULTS: Marginal zone B- and B1-cell specific protein (MZB1) was detected in the tumor stroma. MZB1 expression was positively correlated with a high accumulation of CD8+ TILs. High stromal MZB1 expression also correlated with disease-free and overall survival. In a subgroup analysis of CD8+ expression, there was a significant association between stromal MZB1 expression and disease-free and overall survival in the high CD8+ TIL group. CONCLUSIONS: MZB1 is a potential marker of a high accumulation of CD8+ TILs in borderline resectable PDACs resected after NACRT. Combination of CD8+ TILs with MZB1 may be a new biomarker of resected cases after NACRT. PMID- 29180209 TI - Costunolide protects lipopolysaccharide/d-galactosamine-induced acute liver injury in mice by inhibiting NF-kappaB signaling pathway. AB - BACKGROUND: Costunolide, a well-known sesquiterpene lactone, has been reported to have anti-inflammatory and anti-oxidative effects. METHODS: In this study, we aim to investigate the protective effects and mechanism of costunolide on lipopolysaccharide/d-galactosamine (LPS/D-Gal)-induced acute liver injury. Acute liver injury animal model was induced by intraperitoneal injection with D-Gal and LPS. Costunolide (10, 20, and 30 mg/kg) was injected intraperitoneally 1 h before or after LPS/D-Gal treatment. RESULTS: The results showed that costunolide significantly attenuated liver pathologic changes, as well as alanine aminotransferase and aspartate aminotransferase levels in serum. Meanwhile, costunolide inhibited the expressions of interleukin (IL-1beta) and tumor necrosis factor (TNF-alpha) in liver tissues in a dose-dependent manner. Furthermore, costunolide dose dependently inhibited LPS/D-Gal-induced NF-kappaB activation. CONCLUSIONS: In conclusion, this study suggested that costunolide could attenuate LPS/D-Gal-induced liver injury and might be a potential therapeutic reagent for liver injury. PMID- 29180210 TI - Survival outcomes of neoadjuvant chemotherapy with zoledronic acid for HER2 negative breast cancer. AB - BACKGROUND: A randomized phase 2 trial in women with HER2-negative breast cancer has shown that adding zoledronic acid (ZOL) to neoadjuvant chemotherapy (CT) has potential anticancer benefits in postmenopausal and triple-negative (TN) breast cancer patients. We report the data for the secondary end point of disease-free survival (DFS). METHODS: Patients were randomly assigned to receive CT or CT + ZOL (CT-Z). All patients received four cycles of FEC100 followed by 12 cycles of paclitaxel weekly. ZOL (4 mg) was administered 3-4 times weekly for 7 wk to the CT-Z group patients. The primary end point was pathologic complete response (pCR). The secondary end points were the clinical response rates, rate of breast conserving surgery, safety, and DFS. RESULTS: Of the 188 patients enrolled, 95 were assigned to the CT group and 93 to the CT-Z group. DFS and overall survival were analyzed in 92 and 88 patients with the mean times of 5.15 y and 5.38 y, respectively. The 3-y DFS rate was 84.6% in the CT group and 90.8% in the CT-Z group (P = 0.188). The particular benefit from ZOL for the neoadjuvant CT seen as improvement of the pCR rate was indicated in the 3-y DFS period for TN cancer cases (CT versus CT-Z: 70.6% versus 94.1%) but not for postmenopausal cases. CONCLUSIONS: ZOL did not improve DFS when combined with CT. However, the improvement of the pCR rate translated to survival outcomes in TN breast cancer. The short-term application of ZOL may not be sufficient to improve the outcome in postmenopausal patients. PMID- 29180211 TI - Open versus laparoscopic approach to gastric fundoplication in children with cardiac risk factors. AB - BACKGROUND: Gastric fundoplication is the most common noncardiac operation in children with congenital cardiac disease. While prior studies validated safety of laparoscopy in this population, we hypothesize that children with cardiac risk factors (CRFs) are likelier to undergo open fundoplication (OF) but experience greater morbidity than after laparoscopic fundoplication (LF). MATERIALS AND METHODS: Utilizing 2013 National Surgical Quality Improvement Program-Pediatrics Public-Use-File, pediatric patients undergoing LF and OF were stratified to none, minor, major, or severe CRFs. Multivariate logistic regression determined preoperative variables and postoperative outcomes associated with LF or OF. RESULTS: A total of 1501 fundoplication patients were identified with 92% undergoing LF. OF patients were likelier to have minor (odds ratio [OR]: 2.36, P < 0.001), major (OR: 2.41, P = 0.003), and severe CRFs (OR: 4.36, P < 0.001). Children <= 1 y (OR: 3.38, P = 0.048) and those with tracheostomy were likelier to have OF (OR: 2.3, P = 0.006). Overall, the OF group had higher postoperative morbidity (OR: 2.41, P < 0.001). Specifically, children with minor or major CRFs experienced more complications following OF compared to LF. CONCLUSIONS: OF is more common in patients <=1 y old; patients with minor, major, or severe CRFs; and those with tracheostomy. LF should be considered in children with minor and major CRFs, as OF in those patients results in greater pulmonary, infectious, and hematological sequelae. PMID- 29180212 TI - Patterns of elective lobectomy for lung cancer. AB - BACKGROUND: Lobectomy is the recommended treatment for early-stage lung cancer. Little is known about variations of access to health service areas and hospital types for lobectomy overall and according to specific surgical techniques, such as the video-assisted thoracoscopic surgery (VATS). METHODS: The New York Statewide Planning and Research Cooperative System (2007-2012) was queried for lung cancer patients who underwent elective lobectomy. Hospitals were defined as nearest high-volume hospital (nHVH, reference), distant HVH (dHVH), close or distant low-volume hospital (cLVH or dLVH) using lobectomy volume and travel burden by the distance to nHVH. RESULTS: Utilization of hospitals within patients' health service areas ranged between 44% and 82% for three different geographic units. Approximately 26%, 34%, 31%, and 9% of the 9099 lobectomies were performed in nHVH, dHVH, cLVH, and dLVH, respectively. Patients in nHVH were older and more likely to have private insurance. Patients in dHVH were treated more with VATS and by higher volume surgeons, opposite of what observed in cLVH and dLVH. The use of dHVH was associated with more comorbidities and higher income. The use of dLVH was higher in Hispanics and non-Hispanic blacks than that in non-Hispanic whites. The odds of adverse postoperative events were higher in cLVH and dLVH but lower for patients treated with VATS and by high-volume surgeons. CONCLUSIONS: Multiple factors likely resulted in differences in patterns of elective lobectomy among lung cancer patients. These variations should be taken into account when accessing and planning specialized health care delivery services. PMID- 29180213 TI - Cross talk between TGF beta and TNF alfa in regression of myointimal hyperplasia. AB - BACKGROUND: The phenomena involved in regression of arterial myointimal hyperplasia have not been analyzed in detail. MATERIALS AND METHODS: In 24 Lewis rats, a 1-cm-long venous graft, obtained from syngenic Lewis rats, was implanted in the infrarenal aorta. After 4 wk, the grafts were removed and analyzed using scanning electron microscopy and histochemistry. The grafts showed evidence of myointimal hyperplasia; 16 of these explanted grafts were reimplanted in the vein circulation of syngenic Lewis rats. These grafts were harvested 2 wk (8 animals) and 8 wk (8 animals) later, showing complete regression of myointimal hyperplasia. RESULTS: Regression of experimental myointimal hyperplasia was correlated with the simultaneous and complementary action of Transforming Growth Factor beta and Tumor Necrosis Factor alfa. Inflammatory cytokines (IL1, IL2, and IL6) inhibit Tumor Necrosis Factor alfa-induced apoptosis. CONCLUSIONS: Regression of myointimal hyperplasia is an active process, which implies the action of several inhibitory factors. The analysis of these phenomena can lead to new therapeutic approaches to prevent myointimal hyperplasia progression. PMID- 29180214 TI - Thioredoxin-1 attenuates sepsis-induced cardiomyopathy after cecal ligation and puncture in mice. AB - BACKGROUND: Sepsis is a leading cause of mortality among patients in intensive care units across the USA. Thioredoxin-1 (Trx-1) is an essential 12 kDa cytosolic protein that, apart from maintaining the cellular redox state, possesses multifunctional properties. In this study, we explored the possibility of controlling adverse myocardial depression by overexpression of Trx-1 in a mouse model of severe sepsis. METHODS: Adult C57BL/6J and Trx-1Tg/+ mice were divided into wild-type sham (WTS), wild-type cecal ligation and puncture (WTCLP), Trx 1Tg/+sham (Trx-1Tg/+S), and Trx-1Tg/+CLP groups. Cardiac function was evaluated before surgery, 6 and 24 hours after CLP surgery. Immunohistochemical and Western blot analysis were performed after 24 hours in heart tissue sections. RESULTS: Echocardiography analysis showed preserved cardiac function in the Trx-1Tg/+ CLP group compared with the WTCLP group. Similarly, Western blot analysis revealed increased expression of Trx-1, heme oxygenase-1 (HO-1), survivin (an inhibitor of apoptosis [IAP] protein family), and decreased expression of thioredoxin interacting protein (TXNIP), caspase-3, and 3- nitrotyrosine in the Trx-1Tg/+CLP group compared with the WTCLP group. Immunohistochemical analysis showed reduced 4-hydroxynonenal, apoptosis, and vascular leakage in the cardiac tissue of Trx 1Tg/+CLP mice compared with mice in the WTCLP group. CONCLUSIONS: Our results indicate that overexpression of Trx-1 attenuates cardiac dysfunction during CLP. The mechanism of action may involve reduction of oxidative stress, apoptosis, and vascular permeability through activation of Trx-1/HO-1 and anti-apoptotic protein survivin. PMID- 29180215 TI - Analysis of ischemic muscle in patients with peripheral artery disease using X ray spectroscopy. AB - BACKGROUND: Peripheral artery disease (PAD) is a vascular disease caused by atherosclerosis, resulting in decreased blood flow to the lower extremities. The ankle-brachial index (ABI) is a standard PAD diagnostic test but only identifies reduced blood flow based on blood pressure differences. The early signs of PAD manifest themselves not only at a clinical level but also at an elemental and biochemical level. However, the biochemical and elemental alterations to PAD muscle are not well understood. The objective of this study was to compare fundamental changes in intracellular elemental compositions between control, claudicating, and critical limb ischemia muscle tissue. MATERIALS AND METHODS: Gastrocnemius biopsies from three subjects including one control (ABI >= 0.9), one claudicating (0.4 <= ABI < 0.9), and one critical limb ischemia patient (ABI < 0.4) were evaluated using a scanning electron microscope and energy dispersive X-ray spectroscopy to quantify differences in elemental compositions. Spectra were collected for five myofibers per specimen. An analysis of variance was performed to identify significant differences in muscle elemental compositions. RESULTS: This study revealed that intracellular magnesium and calcium were lower in PAD compared with control myofibers, whereas sulfur was higher. Magnesium and calcium are antagonistic, meaning, if magnesium concentrations go down calcium concentrations should go up. However, our findings do not support this antagonism in PAD. Our analysis found decreases in sodium and potassium, in PAD myofibers. CONCLUSIONS: These findings may provide insight into the pathologic mechanisms that may operate in ischemic muscle and aid in the development of specialized preventive and rehabilitative treatment plans for PAD patients. PMID- 29180216 TI - Pediatric gastrostomy tubes and techniques: making safer and cleaner choices. AB - BACKGROUND: Gastrostomy tube placement is a common procedure that can be accomplished with a variety of techniques, each with its attendant complications. In an effort to standardize practice at our institution, we retrospectively evaluated complications including early dislodgement requiring operative repair, leaks, and granulation tissue to determine the optimal technique. MATERIALS AND METHODS: A retrospective cohort study (June 2008-July 2014) evaluating children (<18) receiving gastrostomy tubes was completed. We recorded demographic data, placement technique, and postoperative complications within 120 days. The seven techniques in use at our institution were categorized into three groups: standard pull-type techniques for percutaneous endoscopic gastrostomies (PEGs), "push" techniques using transabdominal sutures or T-fasteners for securement of the stomach, and "fascial" techniques using sutures directly from the stomach to the abdominal fascia at the stoma site. Descriptive statistics were analyzed using t test and Kruskal-Wallis tests as appropriate, and outcomes with P < 0.05 were considered significant. RESULTS: Of the 450 patients, 255 (56.7%) were male. Median age and weight at the time of operation were 19.3 months (interquartile range, 6.5-89.6 months) and 9.0 kg (interquartile range, 5.7-17.1 kg) respectively. By technique, 245 patients underwent fascial placement (54.4%), 112 underwent push (24.9 %), and 93 underwent PEG (20.7%). Push and fascial techniques were less likely become dislodged than PEG, with odds ratios (ORs) of 0.14 (confidence interval CI 0.02-0.66) and 0.31 (CI 0.11-0.83), respectively. Fascial techniques had more granulation tissue than either push or PEG pull methods, OR 2.39 (CI 1.20-3.36), and more leakage, OR 2.22 (CI 1.19-4.15). CONCLUSIONS: Dislodgement is most likely with PEG techniques. Granulation and leakage are most likely with fascial suture techniques. Push techniques are associated with the lowest complication rate. PMID- 29180217 TI - Comparison of perioperative complications of pedicled island flap in reconstruction of extremities. AB - PURPOSE: The aim of this study was to analyze the differences in perioperative complications for pedicled island flaps in the reconstruction of extremities and to identify the factors contributing to pedicled island flap necrosis. Furthermore, the flap indications based on these outcomes are summarized. METHODS: Based on the inclusion criteria, 228 skin flaps were included in this study. Univariate and multivariate analyses were used to identify the risk factors for pedicled island flap necrosis. Differences in perioperative complications between upper and lower extremities were analyzed using the chi square test or Fisher's exact test. RESULTS: The average age of the patients was 38 years. The overall complication rate was 21.93%, including partial flap necrosis (10.09%) and total flap necrosis (5.70%). The overall complication rate and flap necrosis rate in upper extremity reconstruction were significantly lower than the rates in lower extremity reconstruction. Flap area and postoperative wound infection were statistically significant risk factors for pedicled island flap necrosis in extremity reconstruction. Preoperative contamination of the wound bed was a statistically significant risk factor for postoperative wound infection. CONCLUSIONS: The flap area and postoperative wound infection were both independent risk factors for pedicled island flap necrosis in extremity reconstruction. The causes contributing to the differences in perioperative complications between upper and lower extremities reconstruction included preoperative contamination of the wound bed, postoperative wound infection, and the flap area but were also related to anatomical factors of the skin flap. Pedicled island flaps are more suitable for small- and medium-sized soft tissue defects. PMID- 29180218 TI - A high-throughput solid-phase microextraction and post-loop mixing large volume injection method for water samples. AB - This article presents a novel approach for the analysis of 13 drugs in wastewater for use in wastewater-based epidemiology (WBE) studies. Sample preparation remains one of the principal bottlenecks in modern high-throughput analysis by ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC MS/MS). The proposed methodology is based on the micro-extraction of small volumes (1 ml) of wastewater using a HLB 96-well microplate and both large volume injection (LVI) and post-loop mixing injection (PLM). With this configuration, the limits of quantification (LOQ) were below the reported environmental concentrations of the target compounds in wastewater. Furthermore, both the complexity of collecting, transporting and storing the wastewater sample, sample preparation time, cost and amount of solvent used are all diminished, enhancing the suitability of this methodology for future WBE studies. A new workflow is also proposed in order to create a virtual specimen library bank for WBE by using high-resolution mass spectrometry (HRMS). The method was validated and the limits of quantification were between 0.2 and 6.3 ng L-1. The relative standard deviations (RSD) for a standard mixture at 200 ng L-1 (n = 6) was between 3.4 and 14.4% while the recoveries for the 13 drug target residues (DTR) were between 92 and 110%. The developed and validated method was finally successfully applied to 10 wastewater samples collected from Oslo, Norway. PMID- 29180219 TI - Rapid method for the quantification of 13 sulphonamides in milk by conventional high-performance liquid chromatography with diode array ultraviolet detection using a column packed with core-shell particles. AB - In the present study, a column packed with core-shell particles was used for the separation and the quantification of 13 sulphonamides in milk by conventional high-performance liquid chromatography coupled with diode array ultraviolet detection (HPLC/UV-DAD). Preliminary experiments were carried out to investigate selectivity of different stationary phases. Best results were achieved using a C18 column packed with 2.6MUm core-shell particles (diameter 4.6mm, length 75mm). A binary gradient elution based on acetate buffer solution at pH 4.50 and a mixture of methanol acetonitrile 50:50 (v/v) was employed at the flow rate of 1.2mLmin-1 with an injection volume of 6MUL. These chromatographic conditions allowed the efficient separation of 13 sulphonamides in about 8min. To evaluate the suitability of the method for official control analysis, the most important validation parameters were investigated according to the European Decision 657/2002/EC as established for analysis of drug residues in food. Sulphonamides were recovered from milk samples by a simple and quick preparation procedure consisting of an extraction step with chloroform/acetone and a purification step with n-hexane. Mean recoveries from raw milk ranged between 55% and 86% at the Maximum Residual Limit of 100MUgkg-1, and RSDs% resulted lower than Thompson and Horwitz RSD% reference values for all sulphonamides.

AB - Common reversed-phase columns (C18, C4, phenyl, and cyano) offer inert surfaces suitable for the analysis of polymers by size-exclusion chromatography (SEC). The effect of tetrahydrofuran (THF) solvent and the mixtures of THF with a variety of common solvents used in high performance liquid chromatography (acetonitrile, methanol, dimethylformamide, 2-propanol, ethanol, acetone and chloroform) on reversed-phase stationary phase characteristics relevant to size exclusion were studied. The effect of solvent on the elution of polystyrene (PS) and poly(methyl methacrylate) (PMMA) and the effect of column temperature (within a relatively narrow range corresponding to typical chromatographic conditions, i.e., 10 degrees C-60 degrees C) on the SEC partition coefficients KSEC of PS and PMMA polymers, were also investigated. The bonded phases show remarkable differences in size separations when binary mixtures of THF with other solvents are used as the mobile phase. The solvent impact can be two-fold: (i) change of the polymeric coil size, and possible shape, and (ii) change of the stationary phase pore volume. If the effect of this impact is properly moderated, then the greatest benefit of optimized solute resolution can be achieved. Additionally, this work provides an insight on solvent-stationary phase interactions and their effects on column pore volume. The only effect of temperature observed in our studies was a decreased elution volume of the polymers with increasing temperature. SEC partition coefficients were temperature-independent in the range of 10 degrees C 60 degrees C and therefore, over this temperature range elution of PS and PMMA polymers is by near-ideal SEC on reversed-phase columns. Non-ideal SEC appears to occur for high molar mass PMMA polymers on a cyano column when alcohols are used as mobile phase modifiers. PMID- 29180221 TI - Performance optimization of ultra high-resolution recycling liquid chromatography. AB - The optimization of a twin-column recycling separation process (TCRSP) for maximum resolution or maximum speed-resolution was investigated. The general optimization method was based on the construction of kinetic plots by assuming an ideal TCRSP (no efficiency loss upon recycling). For the optimization, we examined three chromatographic parameters: operation pressure (3000, 6000, 9000, and 12,000psi), column length (10, 15, and 25cm), and column inner diameter (i.d.) (2.1, 3.0, and 4.6mm). Accordingly, the highest TCRSP resolution level is expected for 25cm long columns packed with 2.5, 2.0, 1.7, and 1.6MUm particles at pressures of 3000, 6000, 9000, and 12,000psi, respectively. The maximum speed resolution performance is expected for 10cm columns packed with 3.7, 3.0, 2.6, and 2.4MUm particles. 3.0mm i.d. columns are best to minimize the negative impacts of thermal and inter-column dispersion effects on the TCRSP performance. The method was illustrated for the challenging separation (selectivity factor alpha<1.02) of small molecules in RPLC at a maximum pressure of 6000psi using commercially available columns. Accordingly, 3.0*150mm columns packed with 2.5MUm cellulose-1 Trefoil particles (chiral separation, gamma-phenylbutyrolactone, alpha=1.01, efficiency N=4500) and 2.7MUm Cortecs-C18 particles (isotope separation, alpha=1.02, N=14, 500) particles were found to be the most suitable columns to maximize speed-resolution performance. Further optimization of the TCRSP performance was required by reducing the inter-column sample dispersion that could cause undesirable peak tailing. A standard 2.4MUL Rheodyne valve and 100MUm i.d. tubes were replaced with a home-made 0.5MUL low-dispersion prototype valve and 75MUm i.d. perfect connection tubes. As a result, the experimental resolution factors were increased by +60% (gamma-phenylbutyrolactone, 25 cycles, Rs=0.7->1.1) and +80% (deuterated benzenes, 22 cycles, Rs=1.1->2.0). Direct comparison between the experimental and the predicted TCRSP performance unambiguously demonstrated that the resolution gain was explained by the significant reduction of the peak tailing after a large number of cycles (n>20).

AB - Accumulating evidence suggests that disrupted brain insulin signaling promotes the development and progression of Alzheimer's disease (AD), driving clinicians to target this circuitry. While both traditional and more modern antidiabetics show promise in combating insulin resistance, intranasal insulin appears to be the most efficient method of boosting brain insulin. Furthermore, intranasal delivery elegantly avoids adverse effects from peripheral insulin administration. However, there remain significant open questions regarding intranasal insulin's efficacy, safety, and potential as an adjunct or mono-therapy. Thus, this review aims to critically evaluate the present evidence and future potential of intranasal insulin as a meaningful treatment for AD.

PMID- 29180223 TI - Insulin resistance, an unmasked culprit in depressive disorders: Promises for interventions. AB - Depressive disorders constitute a set of debilitating diseases with psychological, societal, economic and humanitarian consequences for millions of people worldwide. Scientists are beginning to understand the reciprocal communication between the brain and the rest of the body in the etiology of these diseases. In particular, scientists have noted a connection between depressive disorders, which are primarily seen as brain-based, and, insulin resistance (IR), a modifiable metabolic inflammatory state that is typically seen as peripheral. We highlight evidence showing how treating IR, with drugs or behavioral interventions, may ameliorate or possibly prevent, depressive disorders and their long-term consequences at various stages of the life course.

PMID- 29180224 TI - A regulatory perspective on the evaluation of hallucinogen drugs for human use. AB - In recent years, there is renewed interest in the study of various hallucinogens for their potential therapeutic effects. In the United States of America (USA), the abuse potential assessment of a drug is carried out as part of the general safety and efficacy evaluation of a drug. Additionally, the abuse potential assessment is taken under consideration in determining if a drug needs to be subject to controls to minimize the abuse of the drug once on the market. This assessment is conducted for all new drugs with central nervous system (CNS) activity, that are chemically or pharmacologically similar to other drugs with known abuse potential, or drugs that produce psychoactive effects predictive of abuse, such as euphoria and hallucinations. This paper describes the regulatory framework for evaluating the abuse potential of new drugs, with emphasis on hallucinogens. The paper discusses the role of the United States Food and Drug Administration (FDA) in the evaluation of the abuse potential of drugs and its role in drug control, and provides an overview of the controlled status of hallucinogens and the requirements to conduct research with Schedule I substances in the USA.

AB - Aging has been associated with iron retention in many cell types, including the neurons, promoting neurodegeneration by ferroptosis. Excess intracellular iron accelerates aging by damaging the DNA and blocking genomic repair systems, a process we define as ferrosenescence. Novel neuroimaging and proteomic techniques have pinpointed indicators of both iron retention and ferrosenescence, allowing for their early correction, potentially bringing prevention of neurodegenerative disorders within reach. In this review, we take a closer look at the early markers of iron dyshomeostasis in neurodegenerative disorders, focusing on preventive strategies based on nutritional and microbiome manipulations. PMID- 29180226 TI - Microwave radiation leading to shrinkage of dendritic spines in hippocampal neurons mediated by SNK-SPAR pathway. AB - The popularization of microwave raised concerns about its influence on health including cognitive function which is associated greatly with dendritic spines plasticity. SNK-SPAR is a molecular pathway for neuronal homeostatic plasticity during chronically elevated activity. In this study, Wistar rats were exposed to microwaves (30 mW/cm2 for 6 min, 3 times/week for 6 weeks). Spatial learning and memory function, distribution of dendritic spines, ultrastructure of the neurons and their dendritic spines in hippocampus as well as the related critical molecules of SNK-SPAR pathway were examined at different time points after microwave exposure. There was deficiency in spatial learning and memory in rats, loss of spines in granule cells and shrinkage of mature spines in pyramidal cells, accompanied with alteration of ultrastructure of hippocampus neurons. After exposure to 30 mW/cm2 microwave radiation, the up-regulated SNK induced decrease of SPAR and PSD-95, which was thought to cause the changes mentioned above. In conclusion, the microwave radiation led to shrinkage and even loss of dendritic spines in hippocampus by SNK-SPAR pathway, resulting in the cognitive impairments. PMID- 29180227 TI - Mechanism of salvianolic acid B neuroprotection against ischemia/reperfusion induced cerebral injury. AB - The purpose of this study was to evaluate the cerebral protection of salvianolic acid B (Sal B) against cerebral I/R injury and investigate the underlying mechanism. As shown by 2,3,5-Triphenyltetrazolium chloride (TTC) staining and magnetic resonance imaging (MRI) analyses, Sal B significantly reduced cerebral infarct size, and accompanied with improved neurobehavioral functions as indicated by the modified Bederson score and Longa five-point scale. Sal B decreased the production of reactive oxygen species (p < .05, n = 10). The data of Western blotting and reverse transcription quantitative real time polymerase chain reaction (qRT-PCR) analyses showed that the expression of GFAP, Iba1, IL 1beta, IL-6, TNF-alpha and Cleaved-caspase 3 was significantly reduced by Sal B in I/R injured brain tissues as compared to corresponding controls (p < .05, n = 10). Over activation of astrocytes and microglia were inhibited by Sal B as shown by immunostaining of GFAP and Iba 1. These data suggest that Sal B has neural protective effects against I/R-induced cerebral injury and could be an effective candidate for further development of clinical therapy. PMID- 29180228 TI - Telehealth and telenursing using simulation for pre-licensure USA students. AB - An innovative simulation was used to teach pre-licensure USA nursing students about telenursing for screening, assessment, and patient education during a home visit. The students used telepresence technology to deliver nursing care to a homebound geriatric patient. After the simulation, students (N = 73) felt increased confidence with the skills needed to deliver telenursing care and in using telepresence technology. Students reported that they modified and improved their communication in order to adapt to perceived barriers posed by the new technology. As telenursing becomes more prevalent for managing patient care at a distance, nursing programs will need to incorporate educational strategies to reflect this change. PMID- 29180230 TI - Glucocorticoids, genes and brain function. AB - The identification of key genes in transcriptomic data constitutes a huge challenge. Our review of microarray reports revealed 88 genes whose transcription is consistently regulated by glucocorticoids (GCs), such as cortisol, corticosterone and dexamethasone, in the brain. Replicable transcriptomic data were combined with biochemical and physiological data to create an integrated view of the effects induced by GCs. The most frequently reported genes were Errfi1 and Ddit4. Their up-regulation was associated with the altered transcription of genes regulating growth factor and mTORC1 signaling (Gab1, Tsc22d3, Dusp1, Ndrg2, Ppp5c and Sesn1) and progression of the cell cycle (Ccnd1, Cdkn1a and Cables1). The GC-induced reprogramming of cell function involves changes in the mRNA level of genes responsible for the regulation of transcription (Klf9, Bcl6, Klf15, Tle3, Cxxc5, Litaf, Tle4, Jun, Sox4, Sox2, Sox9, Irf1, Sall2, Nfkbia and Id1) and the selective degradation of mRNA (Tob2). Other genes are involved in the regulation of metabolism (Gpd1, Aldoc and Pdk4), actin cytoskeleton (Myh2, Nedd9, Mical2, Rhou, Arl4d, Osbpl3, Arhgef3, Sdc4, Rdx, Wipf3, Chst1 and Hepacam), autophagy (Eva1a and Plekhf1), vesicular transport (Rhob, Ehd3, Vps37b and Scamp2), gap junctions (Gjb6), immune response (Tiparp, Mertk, Lyve1 and Il6r), signaling mediated by thyroid hormones (Thra and Sult1a1), calcium (Calm2), adrenaline/noradrenaline (Adcy9 and Adra1d), neuropeptide Y (Npy1r) and histamine (Hdc). GCs also affected genes involved in the synthesis of polyamines (Azin1) and taurine (Cdo1). The actions of GCs are restrained by feedback mechanisms depending on the transcription of Sgk1, Fkbp5 and Nr3c1. A side effect induced by GCs is increased production of reactive oxygen species. Available data show that the brain's response to GCs is part of an emergency mode characterized by inactivation of non-core activities, restrained inflammation, restriction of investments (growth), improved efficiency of energy production and the removal of unnecessary or malfunctioning cellular components to conserve energy and maintain nutrient supply during the stress response. PMID- 29180229 TI - Peroxisomes contribute to oxidative stress in neurons during doxorubicin-based chemotherapy. AB - Doxorubicin, a commonly used anti-neoplastic agent, causes severe neurotoxicity. Doxorubicin promotes thinning of the brain cortex and accelerates brain aging, leading to cognitive impairment. Oxidative stress induced by doxorubicin contributes to cellular damage. In addition to mitochondria, peroxisomes also generate reactive oxygen species (ROS) and promote cell senescence. Here, we investigated if doxorubicin affects peroxisomal homeostasis in neurons. We demonstrate that the number of peroxisomes is increased in doxorubicin-treated neurons and in the brains of mice which underwent doxorubicin-based chemotherapy. Pexophagy, the specific autophagy of peroxisomes, is downregulated in neurons, and peroxisomes produce more ROS. 2-hydroxypropyl-beta-cyclodextrin (HPbetaCD), an activator of the transcription factor TFEB, which regulates expression of genes involved in autophagy and lysosome function, mitigates damage of pexophagy and decreases ROS production induced by doxorubicin. We conclude that peroxisome associated oxidative stress induced by doxorubicin may contribute to neurotoxicity, cognitive dysfunction, and accelerated brain aging in cancer patients and survivors. Peroxisomes might be a valuable new target for mitigating neuronal damage caused by chemotherapy drugs and for slowing down brain aging in general. PMID- 29180231 TI - Regional gray matter volume and structural network strength in somatic vs. non somatic delusional disorders. AB - BACKGROUND: Monothematic delusional disorders are characterized by a single tenacious belief. They provide a great opportunity to study underlying brain structures in the absence of confounding symptoms that accompany delusions in schizophrenia. Delusional beliefs include persecution, jealousy or somatic delusions including infestation. It is unclear whether specific delusional content is associated with distinct neural substrates. METHODS: We used magnetic resonance imaging in patients presenting with somatic vs. non-somatic delusional disorders. Patients with delusional infestation (DI, n=18), and individuals with non-somatic delusional disorders (n=19) were included, together with healthy volunteers (n=20). Uni- and multivariate techniques for structural data analysis were applied to provide a comprehensive characterization of abnormal brain volume at both the regional and neural network level. RESULTS: Patients with DI showed lower gray matter volume in thalamic, striatal (putamen), insular and medial prefrontal brain regions in contrast to non-somatic delusional disorders and healthy controls. Importantly, these differences were consistently detected at regional and network level. Compared to healthy controls, patients with delusional disorders other than DI showed lower gray matter volume in temporal cortical regions. CONCLUSION: The data support the notion that dysfunctional somatosensory and peripersonal networks could mediate somatic delusions in patients with DI in contrast to delusional disorders without somatic content. The data also suggest putative content-specific neural signatures in delusional disorders and in delusion formation per se.

AB - Ascending thoracic aortic aneurysms (ATAA) are a life-threatening pathology provoking an irreversible dilation with a high associated risk of aortic rupture or dissection and death of the patient. Rupture or dissection of ATAAs remains unpredictable and has been documented to occur at diameters less than 4.5 cm for nearly 60% of patients. Other factors than the aneurysm diameter may highly affect the predisposition to rupture. In order to have a better insight in rupture risk prediction, a bulge inflation bench was developed to test ATAAs samples collected on patients during surgical interventions. Preoperative dynamic CT scans on a cohort of 13 patients were analyzed to estimate volumetric and cross-sectional distensibility. A failure criteria based on in vitro ultimate stretch showed a significant correlation with the aortic membrane stiffness deduced from in vivo distensibility. These results reinforce the significance of stretch-based rupture criteria and their possible non-invasive prediction in clinical practice.

AB - OBJECTIVES: To evaluate the economic impact of future prescriptions of etanercept and adalimumab biosimilars at the territorial scale covered by PharmAlp'Ain, a hospitals grouping of orders for health products. METHODS: Determination of the number and status of patients (naive or in continuation of treatment) from the National Database "Datamart de Consommation Inter-Regimes" of health insurance, concerned by a dispensation in a pharmacy of etanercept or adalimumab in 2015. Calculation of potential savings in case of biosimilar requirements according to 3 hypotheses: 63% (rate observed in a previous study) of initiations are treated with biosimiliaries and the others by princeps (H1); all initiations under biosimilars and continuation therapy with the princeps (H2) or all patients are treated with biosimilars (H3). RESULTS: The annual savings are estimated at 237,000 ? with the H1 hypothesis. In the case of H2, the expected savings would be 376,200 ? per year. In the case of H3, savings for the community could reach almost 1,282,800 ? per year. CONCLUSION: The arrival of biosimilars allows significant savings for medicines market. According to the French recommendations in 2016, the expected savings are between the H1 and H2 hypothesis. The rate of penetration of biosimilars depends on many factors such as the involvement of health professionals, patient adherence, or health authority recommendations.

PMID- 29180238 TI - Glucose homeostasis in the euryhaline crab Cytograpsus angulatus: Effects of the salinity in the amylase, maltase and sucrase activities in the hepatopancreas and in the carbohydrate reserves in different tissues. AB - We studied the existence, biochemical characteristics and response to different environmental salinities of amylase, maltase and sucrase activity in the intertidal euryhaline crab Cyrtograpsus angulatus (Dana, 1852) along with the response to distinct salinities of glycogen and free glucose content in storage organs. Amylase, maltase and sucrase activities were kept over a broad range of pH and temperature and exhibited Michaelis-Menten kinetics. Zymography showed the existence of two amylase forms in crabs exposed to 35 (osmoconformation) and low (6-10psu; hyper-regulation) or high (40psu) (hypo-regulation) salinities. Carbohydrases activity in the hepatopancreas and glycemia were not affected in crab exposed to different environmental salinities. In 6 and 40psu, the glycogen content in anterior gills was lower than in 35psu. In 6, 10 and 40psu, glycogen concentration in hepatopancreas, muscle and posterior gills were similar to that in 35psu. Free glucose concentration in chela muscle was higher in 6 and 40psu than in 35psu. The existence and biochemical characteristics of carbohydrases activity and the adjustments in concentration of glycogen in anterior gills and free glucose in chela muscle suggests the ability to perform complete hydrolysis of glycogenic substrates and to keep glucose homeostasis in relation to acclimation to different salinity conditions. PMID- 29180239 TI - Comparative biochemistry of cytochrome c oxidase in animals. AB - Cytochrome c oxidase (COX), the terminal enzyme of the electron transport system, is central to aerobic metabolism of animals. Many aspects of its structure and function are highly conserved, yet, paradoxically, it is also an important model for studying the evolution of the metabolic phenotype. In this review, part of a special issue honouring Peter Hochachka, we consider the biology of COX from the perspective of comparative and evolutionary biochemistry. The approach is to consider what is known about the enzyme in the context of conventional biochemistry, but focus on how evolutionary researchers have used this background to explore the role of the enzyme in biochemical adaptation of animals. In synthesizing the conventional and evolutionary biochemistry, we hope to identify synergies and future research opportunities. COX represents a rare opportunity for researchers to design studies that span the breadth of biology: molecular genetics, protein biochemistry, enzymology, metabolic physiology, organismal performance, evolutionary biology, and phylogeography.

PMID- 29180241 TI - Generation of semiquinone-[2Fe-2S]+ spin-coupled center at the Qo site of cytochrome bc1 in redox-poised, illuminated photosynthetic membranes from Rhodobacter capsulatus. AB - One of the less understood parts of the catalytic cycle of cytochrome bc1/b6f complexes is the mechanism of electronic bifurcation occurring within the hydroquinone oxidation site (Qo site). Several models describing this mechanism invoke a phenomenon of formation of an unstable semiquinone. Recent studies with isolated cytochrome bc1 or b6f revealed that a relatively stable semiquinone spin coupled to the reduced Rieske cluster (SQ-FeS) is generated at the Qo site during the oxidation of ubi- or plastohydroquinone analogs under conditions of continuous turnover. Here, we identified the EPR transition of SQ-FeS formed upon oxidation of ubihydroquinone in native photosynthetic membranes from purple bacterium Rhodobacter capsulatus. We observed a significant amount of SQ-FeS generated when the antimycin-inhibited enzyme experiences conditions of non equilibrium caused by the continuous light activation of the reaction center. We also noted that SQ-FeS cannot be detected under equilibrium redox titrations in dark. The non-equilibrium redox titrations of SQ-FeS indicate that this center has a higher apparent redox midpoint potential when compared to the redox midpoint potential of the quinone pool. This suggests that SQ-FeS is stabilized, which corroborates a recently proposed mechanism in which the SQ-FeS state is metastable and functions to safely hold electrons at the local energy minimum during the oxidation of ubihydroquinone and limits superoxide formation. Our results open new possibilities to study the formation and properties of this state in cytochromes bc under close to physiological conditions in which non equilibrium is attained by the light activation of bacterial reaction centers or photosystems.

AB - : Cell-free DNA (cfDNA) isolated from plasma or serum has received increasing interest for diagnostic applications in pregnancy, solid tumors and solid organ transplantation. The reported clinical usefulness of cfDNA obtained from plasma or serum in patients undergoing allogeneic cell transplantation (alloHSCT) is scarce. OBJECTIVE: To analyze the potential clinical utility of cfDNA chimerism analysis after alloHSCT. DESIGN AND METHODS: A total of 196 samples obtained from 110 patients were investigated for their chimeric status both in peripheral blood and plasma using standard PCR for microsatellite amplification. Plasma DNA size distribution was analyzed using capillary electrophoresis. RESULTS: The mean cfDNA concentration in the transplanted patients was 469ng/ml (range: 50 10,700ng/ml). The size range of almost 80% of the analyzed fragments was between 80 and 200bp. In 41 out of the 110 patients included in the study a mixture of donor and recipient plasma cfDNA was detected. There was a statistically significant difference in the percentage of plasma mixed chimerism between the patients without transplant related complications and the patients with either GvHD (p<0.05) or relapse (p<0.01). In those patients who showed improvement of GvHD also displayed a decrease in the observable percentage of recipient cfDNA during GvHD treatment. In patients without improvement or even with worsening of acute GvHD, stable or increasing levels of recipient cfDNA were detected. CONCLUSIONS: cfDNA in combination with peripheral blood and bone marrow cell chimerism analysis might improve its utility in the clinic in particular in those patients with clinical complications after alloHSCT. PMID- 29180243 TI - Investigating error-related processing in incarcerated adolescents with self report psychopathy measures. AB - Disparate results have been found in previous reports when incorporating both interview-based and self-report measures of psychopathic traits within the same sample, suggesting such assessments should not be used interchangeably. We previously found Total and Facet 4 scores from Hare's Psychopathy Checklist: Youth Version (PCL:YV) were negatively related to amplitude of the error-related positivity (Pe) event-related potential (ERP) component. Here, we investigated using the same previously published sample whether scores on four different self report measures of adolescent psychopathic traits (the Antisocial Process Screening Device [APSD], Child Psychopathy Scale [CPS], Inventory of Callous Unemotional Traits [ICU], and Youth Psychopathic Traits Inventory [YPI]) were similarly associated with reduced Pe amplitude. Unlike our previous results, adolescent self-report psychopathy scores were not associated with reduced Pe amplitude in multiple regression analyses. Results obtained in the current report support previous research observing incongruent findings when incorporating different assessment types within the same sample. PMID- 29180244 TI - Dual loss of p110delta PI3-kinase and SKAP (KNSTRN) expression leads to combined immunodeficiency and multisystem syndromic features. AB - BACKGROUND: We previously reported a novel syndrome characterized by combined immunodeficiency associated with severe developmental defects-subsequently known as Roifman-Chitayat syndrome (RCS; OMIM 613328). Linkage analysis identified 2 disease-associated loci. OBJECTIVES: We sought to identify the genetic defect in these patients and characterize their immunologic cellular abnormalities. METHODS: Genetic, immunologic, protein, and cellular functional analyses were used to identify and characterize patient genetic deficiencies and aberrant patient cell behavior. RESULTS: Deleterious variants were found at both loci identified by linkage analysis: a homozygous stop codon in PI3-kinase p110delta (PIK3CD) and a homozygous frame shift mutation in SKAP (KNSTRN), both ablating protein expression. Patients with RCS display aberrant B-cell development, similar to p110delta-deficient mice, but also aberrant T-cell spreading, cell cell interaction, and migration. Patients also display significant developmental abnormalities not seen in p110delta knockouts (eg, optic nerve atrophy and skeletal anomalies) that we ascribe to loss of SKAP. Aberrant SKAP expression can prolong anaphase and this may contribute to developmental defects. However, we also identified microtubule-associated protein 4 microtubule-binding protein as a novel SKAP-binding partner and show that it undergoes relocalization in patient T cells, with associated areas of aberrant microtubule hyperstabilization, likely contributing not only to the altered properties of RCS lymphoid cells but also to developmental defects. CONCLUSIONS: The complex RCS presentation, with combined developmental and immunologic defects, is associated with a combined deficiency of 2 genes products, PI3-kinase p110delta and SKAP, both of which appear to play a significant role in the disease. PMID- 29180245 TI - The detection of ACLSV and ASPV in pear plants by RT-LAMP assays. AB - A reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for the detection of Apple chlorotic leaf spot virus (ACLSV) and Apple stem pitting virus (ASPV), two important viruses frequently occurring in pear trees. A set of four RT-LAMP primers designed based on the highly conserved region of each CP gene of the two viruses showed high specificity and feasibility for ACLSV and ASPV detections. The RT-LAMP assays for ACLSV and ASPV in pear samples were 104 and 103 times more sensitive than that of conventional RT-PCR assays. The RT-LAMP under optimal reaction condition was subsequently utilized in the detection of the two viruses in-vitro cultures of pear and field pear samples. This study provides a rapid and sensitive tool to determine the infection statues of the two viruses in pear certification program. PMID- 29180246 TI - The immunohistochemical expression and potential prognostic value of HDAC6 and AR in invasive breast cancer. AB - Previous studies have investigated the role of histone deacetylase 6 (HDAC6) in the regulation of androgen receptor (AR) in prostate cancer; however, the role of HDAC6 has not yet been clearly identified in breast cancer. The aim of this study was to examine the expression of HDAC6 and AR, determine the correlation between HDAC6 and AR, and assess the prognostic value of HDAC6 and AR in breast cancer. A total of 228 cases of invasive breast cancer were randomly selected. The expression of HDAC6 and AR was analyzed by immunohistochemistry. chi2 Tests were performed to determine the association between conventional clinicopathological factors and HDAC6, AR, and HDAC6/AR co-expression. Spearman correlation methods were performed to determine the correlation between HDAC6 and AR, and Kaplan Meier analyses were performed to determine the prognostic impact of HDAC6, AR and HDAC6/AR co-expression; 58.8% (134/228) patients exhibited high expression of HDAC6. High HDAC6 expression was significantly associated with high histologic grade (G3) (P<.001) and p53 overexpression (P=.002). HDAC6 and AR expression levels were significantly associated (r=0.382, P<.01). In estrogen receptor (ER) negative samples, high expression of HDAC6 was more common in the AR+ groups (P<.001) and correlated with high histologic grade (G3) (P=.009), as well as higher HER2 (P=.006) and p53 levels (P=.012). Higher expression of AR and HDAC6 and HDAC6/AR co-expression had a worse clinical prognosis. The expression levels of HDAC6 and AR are correlated in breast cancer; moreover, HDAC6 and AR have prognostic value in predicting the overall survival (OS) of ER-negative breast cancer patients. PMID- 29180247 TI - Fewer seniors from United States allopathic medical schools are filling pathology residency positions in the Main Residency Match, 2008-2017. AB - Some pathologists have observed that fewer trainees from US medical schools are entering pathology residency. This trend was measured and further explored using Main Residency Match (MRM) data from 2008 to 2017, obtained from the National Resident Matching Program (NRMP). Over the past decade, there was an increase of 93 (508 in 2008 versus 601 in 2017, an 18.3% increase) pathology positions offered in the MRM. However, the proportion of pathology residency positions filled in the MRM which were taken by trainees from US medical schools decreased from 77.7% to 50.1% over this timespan. This was primarily due to fewer seniors from US allopathic medical schools filling pathology positions in the MRM (298 in 2008 versus 216 in 2017, a 27.5% decrease). Compared to 14 other medical specialties, pathology had the largest decline in the proportion of residency positions filled in the MRM which were taken by seniors from US allopathic medical schools (63.8% in 2008 versus 39.6% in 2017). Furthermore, pathology now has the lowest percentage of residency positions filled in the MRM, which were taken by seniors from US allopathic medical schools. The primary reason for this decline was because fewer seniors from US allopathic medical schools participated in the MRM for pathology positions (326 in 2008 versus 232 in 2017, a 28.8% decrease); however, the underlying reasons for this decline are unknown. In conclusion, over the past decade, substantially fewer seniors from US allopathic medical schools sought/filled pathology residency positions in the MRM. These findings are relevant for pathology residency recruitment, especially in the context of a projected decline in US pathologist workforce. PMID- 29180248 TI - Transient monoclonal gammopathy induced by Candida fungemia. AB - A 41-year-old woman was admitted for Candida fungemia. On hospital day 4, a routine complete blood count and peripheral smear showed circulating plasma cells. Initial workup showed an M-component on serum protein electrophoresis with 6% lambda-predominate plasma cells by flow cytometry. The patient was treated with intravenous antifungal therapy. Her 6-month follow-up laboratory evaluation revealed resolution of the M-component and only rare polyclonal plasma cells in peripheral blood by flow cytometry. This case illustrates that transient monoclonal gammopathy can be induced by fungal infection. It is important to exclude a plasma cell neoplasm or a B-cell lymphoma and to follow the patient until resolution of abnormal findings. PMID- 29180249 TI - Tumor necrosis in radical prostatectomies with high-grade prostate cancer is associated with multiple poor prognostic features and a high prevalence of residual disease. AB - The Gleason grading system and the recently defined Grade Groups are strong, well established predictors of outcome in prostate cancer. Each Gleason score, however, is the result of a sum of categories (Gleason patterns or GPs) that are intrinsically heterogeneous, as each individual pattern encompasses several tumor morphologies. Although the prognostic value of specific morphologic components of GP4 has recently been demonstrated, the significance of the different patterns of GP5 is largely unknown. We reviewed 344 consecutive prostatectomies performed at the Hospital of the University of Illinois at Chicago between 2011 and 2016 and selected 56 cases with primary or secondary GP5 with archival material available for review. Subsequently, we sorted the cases according to the presence or absence of tumor necrosis in invasive adenocarcinoma GP5-designated G5 (+N) and G5 (-N), respectively-for comparison of histopathologic and clinical characteristics. The GP5 (+N) group demonstrated higher prevalence of biochemical recurrence (P=.0006) and seminal vesicle invasion (P=.02), with a trend toward a higher frequency of lymph node metastases (P=.07) and multifocal surgical margin involvement (P=.09). Also, G5 (+N) patients showed higher preoperative prostate specific antigen values (P=.005) and a larger percentage of submitted tissue involved by tumor (P<.0001). Our results show that GP5 with tumor necrosis is associated with poor prognostic histopathologic features and high rates of residual disease after prostatectomy. PMID- 29180250 TI - High interlaboratory and interobserver agreement of somatostatin receptor immunohistochemical determination and correlation with response to somatostatin analogs. AB - Monoclonal antibodies to somatostatin receptors 2A (SSTR2A, UMB-1) and 5 (SSTR5, UMB-4) were reported to be highly reliable for immunohistochemical detection of these receptors in neuroendocrine neoplasms. However, the standardization of either the immunohistochemical procedure and the methods of evaluation has yet to be established. Fifty-two tissues from 38 patients with neuroendocrine neoplasm were retrieved from 2 institutions in Italy and Japan. The tissues were immunostained using 3 staining methodologies: 1 automated and 2 manual protocols from the Italian and Japanese institutions. The slides were independently evaluated by 3 observers (2 experienced pathologists and 1 medical student) using 3 scoring systems (Volante-Score, HER2-Score, and H-Score). The scores obtained from the staining methods were highly correlated with each other (r>0.85, P<.0001). Especially, the Volante- and HER2-Scores were highly concordant (r>=0.95, P<=.0001). Very high interobserver agreement was obtained irrespective of the method used and the experience of the evaluator, with the best concordance obtained by experienced pathologists evaluating automated system-stained slides (SSTR2A, r>0.97; SSTR5, r>0.96). HER2- and H-Scores were reliable to represent the characteristics of the patients. SSTR2A expression evaluated by the HER2 Score was significantly associated with clinical efficacy to somatostatin analogs (P=.04). SSTRs determination is an easily standardizable tool in different laboratories and is highly reproducible irrespective of the method of evaluation used. Given the positive association with clinical efficacy to somatostatin analogs, as well as the simple and widespread use, HER2-Score can be proposed as a standard evaluation procedure of SSTR2A and SSTR5 expression in neuroendocrine neoplasms. PMID- 29180251 TI - Renal cell carcinoma with angioleiomyoma-like stroma and clear cell papillary renal cell carcinoma: exploring SDHB protein immunohistochemistry and the relationship to tuberous sclerosis complex. AB - Renal cell carcinoma (RCC) with angioleiomyoma-like stroma appears to be molecularly distinct from clear cell RCC; however, its relationship to clear cell papillary RCC remains debated. Recent studies have found that similar tumors sometimes occur in patients with tuberous sclerosis complex (TSC), of which 1 study found unexpectedly negative succinate dehydrogenase B (SDHB) immunostaining. We evaluated immunohistochemistry for SDHB in 12 apparently sporadic RCCs with angioleiomyoma-like stroma and correlated with clinical information for stigmata of TSC. Tumors were compared with a group of 16 clear cell papillary RCCs and 6 unclassified tumors with prominent stroma. With the exception of 1 unclassified tumor, all exhibited at least focal cytoplasmic staining for SDHB protein, often requiring high magnification and better appreciated with increased antibody concentration. Detailed history information was available for 9 of 11 patients with smooth muscle-rich tumors, revealing no stigmata of undiagnosed TSC. Electron microscopy performed on 1 of these tumors revealed mitochondria to be very sparse, potentially accounting for the weak immunohistochemical labeling for SDHB protein. Weak SDHB immunostaining may represent another shared feature of RCC with angioleiomyoma-like stroma and clear cell papillary RCC, likely due to sparse mitochondria, strengthening the possible relationship of these entities. Although smooth muscle-rich tumors have been recently reported in patients with TSC, absence of staining in tumors with this pattern may not be specific for TSC. In tumors with pale or clear cytoplasm, immunohistochemical staining for SDHB should be interpreted with caution as evidence of abnormality in the SDH pathway. PMID- 29180252 TI - Distinction of intrahepatic metastasis from multicentric carcinogenesis in multifocal hepatocellular carcinoma using molecular alterations. AB - Patients with hepatocellular carcinoma (HCC) frequently have multiple anatomically distinct tumors. In these patients, multifocal HCC could represent intrahepatic metastases (IMs) of a single cancer or multicentric carcinogenesis (MC) with multiple independent neoplasms. To determine the frequency and clinical implications of these 2 possibilities, we performed histological and molecular analysis of 70 anatomically distinct HCCs from 24 patients. We assayed mutations in the TERT promoter region by Sanger sequencing and used next-generation sequencing to analyze the entire coding regions of 7 well-characterized HCC driver genes-based on shared or discordant mutations in these genes, we classified the HCCs in each patient as IM, MC, or indeterminate. Mutations in the TERT promoter were the most common alteration in our cohort, present in 71% of tumors analyzed. Mutations in the remaining genes occurred in less than 20% of analyzed tumors. We were able to determine the relatedness in 58% of the patients analyzed: MC occurred in 41% of patients, with 33% with exclusively MC and 8% with both MC and IM. IM occurred exclusively in 17% of patients, whereas the remainder were indeterminate. This study highlights the utility of molecular analyses to determine relatedness in multifocal HCC; however, targeted sequencing can only resolve this distinction in approximately 60% of patients with multifocal HCC. PMID- 29180253 TI - Pathology and radiology correlation of idiopathic interstitial pneumonias. AB - By nature, idiopathic interstitial pneumonias have been diagnosed in a multidisciplinary manner. As classifications have been subject to significant refinement over the last decade, the importance of correlating clinical, radiologic, and pathologic information to arrive at a diagnosis, which will predict prognosis in any given patient, has become increasingly recognized. In 2013, the American Thoracic Society and European Respiratory Society updated the idiopathic interstitial pneumonias classification scheme, addressing the most recent updates in the field. The purpose of this review is to highlight the correlations between radiologic and pathologic findings in idiopathic interstitial pneumonias while using updated classification schemes and naming conventions. PMID- 29180254 TI - Reclaiming hijacked phagosomes: Hybrid nano-in-micro encapsulated MIAP peptide ensures host directed therapy by specifically augmenting phagosome-maturation and apoptosis in TB infected macrophage cells. AB - TB-Superbugs have emerged as one of the most challenging global health threat due to the decrease in effectiveness of conventional antibiotics. Meanwhile, Host defense peptides (HDP) have evolved as an alternative to classical therapeutics with lesser susceptibility of resistance. We describe the potential of nano encapsulated synthetic Magainin-I analog peptide (MIAP) as Host Directed Therapy against TB. Micron-sized inhalable platform "Porous Nanoparticle Aggregates Particles (PNAP)" with nano-scale physiognomies were developed to improve the delivery of MIAP-peptide to the lungs and enhance its stability. This particle engineering enabled more control over aerodynamic characteristics and bioactive release. Antimicrobial and mechanistic studies were carried out against virulent H37Rv TB bacteria. These MIAP-PNAP nano-assemblies demonstrated dose and time dependent antibacterial action against virulent M.tb for at least 96 h, with up to ~3.03-log CFU reduction in numbers of viable bacteria compared to untreated group. These MIAP-PNAP at concentration of 50 MUM and above showed significant antibacterial effects on M.tb after 48-96 h of incubation. Mechanistically, MIAP nano-formulation enhanced host defense mechanism by averting bacteria-induced inhibition of phagosomal-lysosome fusion (Lysostracker) and apoptosis (Annexin FITC) as shown by confocal microscopy and flow-cytometry. Encapsulated MIAP may serve for adjunctive host-directed TB therapy which may also synergizes the efficacy of standard anti-TB drugs. PMID- 29180255 TI - Nanoparticle-loaded hydrogels as a pathway for enzyme-triggered drug release in ophthalmic applications. AB - The aim of this study was to develop nanoparticle loaded hydrogel based contact lenses that could be used for ocular drug delivery. Two potential contact lens platforms for controlled ophthalmic drug delivery were developed by incorporating chitosan-poly (acrylic acid) nanoparticles into polyvinyl alcohol (PVA) hydrogels and in-situ gelled nanoparticles and cellulose nanocrystals (CNC) in PVA lenses. The nanoparticles were shown to disintegrate in a physiological 0.2 mM concentration of lysozyme resulting from the hydrolysis of the chitosan chains by lysozyme. An extended release over a 28-h period was demonstrated once the nanoparticles had been integrated into the composite lenses, with nanoparticle CNC PVA lenses showing even greater potential for extended release. The platform shows great promise in developing enzyme-triggered ocular drug delivery systems. PMID- 29180256 TI - Effects of solvents on skin absorption of nonvolatile lipophilic and polar solutes under finite dose conditions. AB - The effects of solvents upon the deposition of a moderately lipophilic solute on skin and skin permeation were investigated previously. The present study was a continuing effort to investigate the effects of solvents on finite dose skin absorption of nonvolatile lipophilic and polar solutes and examine the relationships between solute physicochemical properties, solvent effects, and skin absorption of these solutes after solvent deposition. Skin permeation experiments under the finite dose conditions were conducted with model solutes (corticosterone, urea, mannitol, glycerol, triamcinolone acetonide, and estradiol) and model solvents (ethanol, butanol, water, and propylene glycol) using Franz diffusion cells and human epidermal membrane. Urea showed unexpectedly high skin permeation under the finite dose conditions compared to the other solutes based on their skin permeability coefficients (obtained under infinite dose condition). The influences of the solvents on solute permeation suggest that these solvents did not act solely as a vehicle for spreading the solutes during solvent deposition. In the testing of skin permeation mechanisms, model analyses indicated a correlation between solute permeation and their molecular weights and solubilities, suggesting that the solute permeation mechanism with the volatile solvent was related to solute dissolution on the skin surface and its diffusion across the skin. PMID- 29180257 TI - Insights on animal models to investigate inhalation therapy: Relevance for biotherapeutics. AB - Acute and chronic respiratory diseases account for major causes of illness and deaths worldwide. Recent developments of biotherapeutics opened a new era in the treatment and management of patients with respiratory diseases. When considering the delivery of therapeutics, the inhaled route offers great promises with a direct, non-invasive access to the diseased organ and has already proven efficient for several molecules. To assist in the future development of inhaled biotherapeutics, experimental models are crucial to assess lung deposition, pharmacokinetics, pharmacodynamics and safety. This review describes the animal models used in pulmonary research for aerosol drug delivery, highlighting their advantages and limitations for inhaled biologics. Overall, non-clinical species must be selected with relevant scientific arguments while taking into account their complexities and interspecies differences, to help in the development of inhaled medicines and ensure their successful transposition in the clinics. PMID- 29180258 TI - Ten simple rules for neuroimaging meta-analysis. AB - Neuroimaging has evolved into a widely used method to investigate the functional neuroanatomy, brain-behaviour relationships, and pathophysiology of brain disorders, yielding a literature of more than 30,000 papers. With such an explosion of data, it is increasingly difficult to sift through the literature and distinguish spurious from replicable findings. Furthermore, due to the large number of studies, it is challenging to keep track of the wealth of findings. A variety of meta-analytical methods (coordinate-based and image-based) have been developed to help summarise and integrate the vast amount of data arising from neuroimaging studies. However, the field lacks specific guidelines for the conduct of such meta-analyses. Based on our combined experience, we propose best practice recommendations that researchers from multiple disciplines may find helpful. In addition, we provide specific guidelines and a checklist that will hopefully improve the transparency, traceability, replicability and reporting of meta-analytical results of neuroimaging data. PMID- 29180259 TI - Post-Operative Cognitive Dysfunction: An exploration of the inflammatory hypothesis and novel therapies. AB - Post-Operative Cognitive Dysfunction (POCD) is a highly prevalent condition with significant clinical, social and financial impacts for patients and their communities. The underlying pathophysiology is becoming increasingly understood, with the role of neuroinflammation and oxidative stress secondary to surgery and anaesthesia strongly implicated. This review aims to describe the putative mechanisms by which surgery-induced inflammation produces cognitive sequelae, with a focus on identifying potential novel therapies based upon their ability to modify these pathways. PMID- 29180260 TI - A novel de novo activating mutation in STAT3 identified in a patient with common variable immunodeficiency (CVID). AB - Common variable immunodeficiency (CVID) is characterised by repeated infection associated with primary acquired hypogammaglobulinemia. CVID frequently has a complex aetiology but, in certain cases, it has a monogenic cause. Recently, variants within the gene encoding the transcription factor STAT3 were implicated in monogenic CVID. Here, we describe a patient presenting with symptoms synonymous with CVID, who displayed reduced levels of IgG and IgA, repeated viral infections and multiple additional co-morbidities. Whole-exome sequencing revealed a de novo novel missense mutation in the coiled-coil domain of STAT3 (c.870A>T; p.K290N). Accordingly, the K290N variant of STAT3 was generated, and a STAT3 responsive dual-luciferase reporter assay revealed that the variant strongly enhances STAT3 transcriptional activity both under basal and stimulated (with IL-6) conditions. Overall, these data complement earlier studies in which CVID-associated STAT3 mutations are predicted to enhance transcriptional activity, suggesting that such patients may respond favourably to IL-6 receptor antagonists (e.g. tocilizumab). PMID- 29180261 TI - Optimal choice of k-mer in composition vector method for genome sequence comparison. AB - Several proteins and genes are members of families that share a public evolutionary. In order to outline the evolutionary relationships and to recognize conserved patterns, sequence comparison becomes an emerging process. The current work investigates critically the k-mer role in composition vector method for comparing genome sequences. Generally, composition vector methods using k-mer are applied under choice of different value of k to compare genome sequences. For some values of k, results are satisfactory, but for other values of k, results are unsatisfactory. Standard composition vector method is carried out in the proposed work using 3-mer string length. In addition, special type of information based similarity index is used as a distance measure. It establishes that use of 3-mer and information based similarity index provide satisfactory results especially for comparison of whole genome sequences in all cases. These selections provide a sort of unified approach towards comparison of genome sequences. PMID- 29180262 TI - Inhibition of HSF2 SUMOylation via MEL18 upregulates IGF-IIR and leads to hypertension-induced cardiac hypertrophy. AB - Cardiac hypertrophy is a major characteristic of early-stage hypertension-related heart failure. We have found that the insulin-like growth factor receptor II (IGF IIR) signaling was critical for hypertensive angiotensin II-induced cardiomyocyte hypertrophy and apoptosis. Moreover, this IGF-IIR signaling was elegantly modulated by the heat shock transcription factors (HSFs) during heart failure. However, the detailed mechanism by which HSFs regulates IGF-IIR during hypertension-induced cardiac hypertrophy remains elusive. In this study, we found that heat shock transcription factor 2 (HSF2) activated IGF-IIR to induce cardiac hypertrophy for hypertension-induced heart failure. The transcriptional activity of HSF2 appeared to be primarily mediated by SUMOylation via conjugation with small ubiquitin-like modifier-1 (SUMO-1). The SUMOylation of HSF2 was severely attenuated by MEL18 (also known as polycomb group ring finger 2 or PCGF2) in the heart of spontaneously hypertensive rats (SHR). Inhibition of HSF2 SUMOylation severely induced cardiac hypertrophy via IGF-IIR-mediated signaling in hypertensive rats. Angiotensin II receptor type I blocker (ARB) treatment in spontaneously hypertensive rats restored HSF2 SUMOylation and alleviated the cardiac defects. Thus, our study uncovered a novel MEL18-SUMO-1-HSF2-IGF-IIR pathway in the heart that profoundly influences cardiac hypertrophy for hypertension-induced heart failure. PMID- 29180263 TI - Polypill, hypertension and medication adherence: The solution strategy? AB - INTRODUCTION: Hypertension is an important global health challenge and a leading preventable risk factor for premature death and disability worldwide. In current cardiology practice, the main obstacles in the management of patients affected by hypertension are comorbidities and poor adherence to pharmacological treatments. The World Health Organization has recently highlighted increased adherence as a key development need for reducing cardiovascular disease. METHODS: Principal observational and clinical trial data regarding adherence, reductions in cardiovascular risk and safety of the polypill approach are summarized and reviewed. CONCLUSIONS: The polypill approach has been conclusively shown to increase adherence relative to usual care in all cardiovascular patients, furthermore, concomitant risk factor reductions have also been suggested. To date, the use of polypill could represent a solution strategy in patients affected by hypertension, comorbidities and non-adherence even though further studies, especially in the real-world settings, are needed in order to better understand its role in clinical practice. PMID- 29180264 TI - Impact of persistent ST elevation on outcome in patients with Takotsubo syndrome. Results from the GErman Italian STress Cardiomyopathy (GEIST) registry. AB - BACKGROUND: Potential predictors of clinical complications of Takotsubo syndrome (TTS) are poorly known. Persistent ST-segment elevation (PSTE) may have an impact on outcome similar as previously reported in acute coronary syndrome. The aim of this study was to assess the prevalence and prognostic relevance of PSTE in patients with TTS. METHODS: Two-hundred-sixty-nine consecutive patients were enrolled in an international multicenter registry. PSTE was defined as the documentation of ST-elevation at least for the first 48h of hospitalization. Long term mortality was evaluated in median 1.9years after the acute event. RESULTS: PSTE was found in 52 TTS patients (19%). Patients with PSTE were characterized by higher admission levels of troponin-I (23+/-12 vs 8+/-49ng/L, p<0.001), experienced a longer hospitalization (10+/-5 vs 8+/-3days, p=0.02) and a higher rate of in-hospital complications (31% vs 17% p=0.03). At multivariate analysis including PSTE, age, male sex, admission ejection fraction, PSTE (odds ratio [OR] 4.2; 95% confidence interval [CI] 1.4-13; p=0.01), age (OR 1.05; 95%CI 1.00-1.10; p=0.03) and admission ejection fraction (OR 0.93; 95%CI 0.87-0.99; p=0.02) were independent predictors of in-hospital complications. At long-term follow-up no significant differences in terms of mortality were observed between patients with and without PSTE (19% vs 15%; p=0.5). However, PSTE was a predictor of major cardiac adverse events (MACE) at follow-up (HR 2.32, 95% CI 1.02-5.31, p 0.045). CONCLUSIONS: In TTS patients, PSTE is a common finding, represents an independent predictor of in-hospital complications and could be associated with MACE at follow-up.

AB - BACKGROUND: Patients diagnosed as affected by Brugada syndrome (BrS) on the basis of a drug-induced type 1 ECG pattern (type1) are regarded as at low risk for cardiac arrest. We tested whether this assumption matches reality. METHODS: The study population included 26 patients from our group and 217 patients from three studies published between 2002 and 2013, all of them with aborted cardiac arrest (ACA) and in whom a previously unrecognized type1 (spontaneous or drug-induced) was discovered after the event, thus leading to the diagnosis of BrS. RESULTS: Among our 26 patients, a drug-induced type1 was detected in 11 (42%) and only 1/11 showed a spontaneous pattern during follow-up; of 6 patients with syncope before ACA, 4 (67%) had only a drug-induced pattern. ICD shocks rates were similar in both spontaneous and drug-induced groups (57% and 45%). Early on, year 2002, the percentage of drug-induced type1 after ACA was much lower (14%) and has progressively increased to approximately 50%. CONCLUSIONS: If drug-induced type1 carries low arrhythmic risk, it should seldom be the only marker for BrS after an ACA. In studies on patients after an unexpected ACA, a drug-induced type1 leads to the diagnosis of BrS more often than anticipated. This contrasts with prospective studies focusing on patients already diagnosed as BrS and which consider drug-induced type1 as a marker of low risk. Contrary to current views, it is possible that not all patients with a drug-induced BrS type1 are at low risk of future events.

PMID- 29180269 TI - Dysregulation of antioxidant responses in patients diagnosed with concomitant Primary Sclerosing Cholangitis/Inflammatory Bowel Disease. AB - OBJECTIVE: Primary Sclerosing Cholangitis (PSC) is a chronic cholestatic liver disease that is characterized by severe peri-biliary tract inflammation and fibrosis, elevated oxidative stress and hepatocellular injury. A hallmark of PSC patients is the concurrent diagnosis of Inflammatory Bowel Disease occurring in approximately 70%-80% of PSC patients (PSC/IBD). The objective of this study was to determine the impact of end stage PSC/IBD on cellular antioxidant responses and the formation of protein carbonylation. METHODS: Using hepatic tissue and whole cell extracts isolated from age-matched healthy humans and patients diagnosed with end stage PSC/IBD, overall inflammation, oxidative stress, and protein carbonylation were assessed by Western blotting, and immunohistochemistry. RESULTS: Increased immunohistochemical staining for CD3+ (lymphocyte), CD68 (Kupffer cell) and myeloperoxidase (neutrophil) colocalized with the extensive Picrosirius red stained fibrosis confirming the inflammatory aspect of PSC. Importantly, the increased inflammation also colocalized with elevated periportal post-translational modification by the reactive aldehydes 4 HNE, MDA and acrolein. 4-HNE, MDA and acrolein IHC all displayed a significant component in hepatocytes adjacent to fibrotic regions. Furthermore, acrolein was also elevated within the nuclei of periportal inflammatory cells whereas MDA staining was increased in hepatocytes across the lobule. Prussian Blue staining, when compared to the positive controls (ALD, NASH), did not display any evidence of iron accumulation in PSC/IBD livers. Western analysis of PSC/IBD anti-oxidant responses revealed elevated expression of SOD2, GSTpi as well as upregulation of Akt Ser473 phosphorylation. In contrast, expression of GSTMU, GSTA4, catalase, Gpx1 and Hsp70 were suppressed. These data were further supported by a significant decrease in measured GST activity. Dysregulation of anti-oxidant responses in the periportal region of the liver was supported by elevated SOD2 and GSTpi IHC signals in periportal hepatocytes and cholangiocytes. Expression of the Nrf2-regulated proteins HO-1, NAD(P)H quinone reductase (NQO1) and Gpx1 was primarily localized to macrophages. In contrast, catalase staining decreased within periportal hepatocytes and was not evident within cholangiocytes. CONCLUSIONS: Results herein provide additional evidence that cholestasis induces significant increases in periportal oxidative stress and suggest that there are significant differences in the cellular and subcellular generation of reactive aldehydes formed during cholestatic liver injury. Furthermore, these data suggest that anti-oxidant responses are dysregulated during end-stage PSC/IBD supporting pathological data. This work was funded by NIH5R37AA009300-22 D.R.P. PMID- 29180271 TI - Reconstructive techniques for revision and limb salvage surgery in persons with haemophilia. AB - Haemophilia is an inherited haemorrhagic disease characterized by the lack of coagulative factors associated nowadays mostly to musculoskeletal complications, particularly severe secondary arthritis in specific joints. Recurrent traumatic or spontaneous joint bleeding, induce severe arthropathy at a young age that can be treated only by joint replacement. Total knee or hip arthroplasty in young subjects may fail earlier due to wear or infections and in the haemophilic population, this means bone loss, pseudo tumours and the need of revision or even limb salvage surgery. Modern modular implants and the use of bone graft enriched by tissue engineering techniques such as a concentration of autologous mesenchymal cells or PRP may be helpful to compensate all bone loss and anatomic alterations due to failures of orthopaedic implants. The authors present their experience with this type of surgery and their biological approach to these challenging cases.

PMID- 29180273 TI - Evaluation of vitrification protocol of mouse ovarian tissue by effect of DNA methyltransferase-1 and paternal imprinted growth factor receptor-binding protein 10 on signaling pathways. AB - Transplantation of cryopreserved ovarian tissue has been considered as a promising way of fertility preservation for women. however, this cryopreservation method is prone to post-resuscitation follicle proliferation and oocyte development stagnation, affecting late transplant survival. To evaluate current vitrification works, we investigated the critical pathway alternations in vitrified-warmed juvenile 10-day-old mouse ovary. We showed a significant decrease of protein kinase B (Akt) and Mitogen-activated protein kinase (Mapk) phosphorylation, during which serine/threonine kinases play central roles in coordinating follicle and oocyte development and stress response. Inhibition of Akt and Mapk activity were associated with one of the imprinted insulin pathway negative regulatory genes, Growth factor receptor-binding protein 10 (Grb10) which remarkably increased in vitrified-warmed juvenile mouse ovary than that of fresh group (p < 0.05). RNAi-induced Grb10 down-regulation reversed the decrease in Akt and Mapk phosphorylation. The increase of Grb10 expression was partially caused by the hyper-methylation of the promoter region, associated with the decrease of follicular DNA methyltransferase (Dnmt) 1 protein in different stages of vitrified-warmed group, compared to fresh group (p < 0.05). The mRNA and protein expression of Dnmt1 in ovary of vitrified-warmed juvenile mouse were remarkably lower than those in fresh group (p < 0.05). Dnmt1 overexpression dramatically reversed Grb10 up-regulation and Akt and Mapk phosphorylation reduction. Taken together, our findings suggest that Grb10 expression might be helpful in evaluation of effectiveness of vitrification, and considered as a potential target for further vitrification protocols improvement in the future. PMID- 29180274 TI - Protocol for cryopreservation of the turbot parasite Philasterides dicentrarchi (Ciliophora, Scuticociliatia). AB - Philasterides dicentrarchi is a free-living marine ciliate that can become an endoparasite that causes a severe disease called scuticociliatosis in cultured fish. Long-term maintenance of this scuticociliate in the laboratory is currently only possible by subculture, with periodic passage in fish to maintain the virulence of the isolates. In this study, we developed and optimized a cryopreservation protocol similar to that used for the long-term storage of scuticociliates of the genus Miamiensis. The cryogenic medium comprised ATCC medium 1651 and a combination of 11% dimethylsulfoxide and 5% glycerol. We have verified that the most important factor ensuring the efficiency of the cryopreservation procedure is the growth phase of the culture, and that ciliates should be cryopreserved at the stationary phase (around the sixth day of culture). The cryopreservation protocol described here can be used for all strains of P. dicentrarchi as well as commercial strains of Miamiensis and enables the virulence of the strains to be maintained. Finally, this cryopreservation protocol has been shown to be more effective than others routinely applied to scuticociliates, yielding a higher survival rate with a lower initial concentration of ciliates. The results obtained indicate that the cropreservation protocol enables the long-term storage of scuticociliate parasites while maintaining the virulence of the isolates. The protocol is therefore suitable for use in vaccine production and related studies. PMID- 29180275 TI - [Exhaustivity and critical tone of the news in print media reporting medical innovations]. AB - OBJECTIVE: To quantify how exhaustive and critical were stories reporting medical innovations published in print media and to analyze the characteristics that may be related. METHOD: Content analysis of the newspapers stories related to the discovery, introduction or improvement of a medical innovation through a questionnaire with ten criteria that allows calculating an overall score of exhaustiveness. The critical view was also included. RESULTS: We analyzed 204 newspapers stories that on average obtained a comprehensiveness score of 4.5. Were optimistic 70% of the stories. The most valued criteria were: level of detail of the explanation of the innovation and the correct differentiation between facts and opinions. While the worst-valued criteria were: disclosure of financial conflicts of interest and the quantification of harms. The variables author, length of the story and classification of the innovation were related to both the comprehensiveness score and the critical view. The comprehensiveness score was also related to the pathology, number of sources of information and the critical tone of the story, while the critical view was also related to the newspapers diffusion and the relevance of the news. CONCLUSIONS: The analyzed stories presented inaccuracies, biases or an excess of optimism (either intentional or involuntary). Some aspects of the stories discussed in more detail would provide solutions to many of the identified shortcomings.

AB - Dalbavancin is a lipoglycopeptide with a very prolonged half-life enabling treatment with a single intravenous administration that has been approved to treat complicated skin and soft-tissue infections. Information on the efficacy and safety of dalbavancin in other situations is very scarce. This retrospective study included adult patients who received at least one dose of dalbavancin between 2016 and 2017 in 29 institutions in Spain. The primary objective was to report the use of dalbavancin in clinical practice, including its efficacy and tolerability. The potential impact of dalbavancin on reducing the length of hospital stay and hospital costs was also evaluated. A total of 69 patients received dalbavancin during the study period (58.0% male; median age 63.5 years). Dalbavancin was used to treat prosthetic joint infection (29.0%), acute bacterial skin and skin-structure infection (21.7%), osteomyelitis (17.4%) and catheter related bacteraemia (11.6%). These infections were mainly caused by Staphylococcus aureus (27 isolates), coagulase-negative staphylococci (24 isolates) and Enterococcus spp. (11 isolates). All but two patients received previous antibiotics for a median of 18 days. Dalbavancin was administered for a median of 21 days (range 7-168 days), and concomitant antimicrobial therapy was prescribed to 25 patients (36.2%). The overall clinical success rate of dalbavancin was 84.1%. Adverse events, mainly mild in intensity, were reported in nine patients. Overall, dalbavancin was estimated to reduce hospitalisation by 1160 days, with an estimated overall cost reduction of ?211 481 (?3064 per patient). Dalbavancin appears to be an effective therapy for many serious Gram positive infections. PMID- 29180278 TI - Higher versus standard amikacin single dose in emergency department patients with severe sepsis and septic shock: a randomised controlled trial. AB - Recent studies suggest that intensive care unit patients treated with amikacin frequently do not attain the desired pharmacokinetic/pharmacodynamic (PK/PD) target, i.e. peak amikacin concentration (Cpeak) to minimum inhibitory concentration (MIC) ratio of >=8, when a single dose of 15 mg/kg is used. No data are available for patients admitted to the emergency department (ED). The aim of this prospective randomised controlled study was to determine PK/PD target attainment in ED patients presenting with severe sepsis or septic shock treated with 15 mg/kg versus 25 mg/kg amikacin. Patients were randomly assigned to receive amikacin 25 mg/kg or 15 mg/kg. Amikacin Cpeak values were determined. The primary outcome was target attainment defined as Cpeak/MIC >= 8 both using EUCAST susceptibility breakpoints and actually documented MICs as denominator. A total of 104 patients were included. The EUCAST-based target was attained in 76% vs. 40% of patients assigned to the 25 mg/kg vs. 15 mg/kg dose groups (P <0.0001). Target attainment using actual MICs (median of 2 mg/L, documented in 48 isolated Gram-negative pathogens) was achieved in 95% vs. 94% of patients in the 25 mg/kg vs. 15 mg/kg dose groups (P = 0.969). Risk factors associated with PK/PD target failure were identified in the multivariable analysis. At least 25 mg/kg amikacin as a single dose should be used in ED patients with severe sepsis and septic shock to attain the EUCAST-based PK/PD target. However, when using local epidemiology as denominator, 15 mg/kg appears to be sufficient. [ClinicalTrials.gov ID: NCT02365272. PMID- 29180279 TI - Impact of the colistin resistance gene mcr-1 on bacterial fitness. AB - A Klebsiella pneumoniae isolate harbouring a 217 kb IncHI2-type plasmid (pKP2442) encoding the colistin resistance gene mcr-1 was isolated from a leukaemia patient. pKP2442 was mobilised by intragenus and intergenus transconjugation from the clinical isolate to Escherichia coli J53 (transconjugation frequency 6.86 * 10-8 +/- 5.57 * 10-8) and K. pneumoniae PRZ (transconjugation frequency 4.04 * 10 8 +/- 3.03 * 10-8), respectively. Since acquisition of resistance determinants often results in a loss of fitness, the impact of mcr-1 on the fitness of E. coli and K. pneumoniae was investigated. Escherichia coli J53 and K. pneumoniae PRZ transformants harbouring the TOPO expression vector encoding mcr-1 displayed significantly decreased growth rates compared with isogenic parental strains and controls. In contrast, competitive growth experiments revealed equal growth rates between E. coli J53 pKP2442 transconjugants (TcpKP2442) and the parental strain, whereas K. pneumoniae PRZ TcpKP2442 showed significantly reduced growth rates compared with their parental strain (selection rate constant -1.62 +/- 0.49), indicating a decrease in fitness. Infection of A549 human lung epithelial cells with TcpKP2442 or mcr-1 transformants and controls revealed equal lactate dehydrogenase activities, indicating no significant impact of mcr-1 on cytotoxicity. Likewise, survival of Galleria mellonella larvae infected with mcr 1-expressing strains and isogenic controls was similar. These data indicate that expression of mcr-1 is able to cause a fitness cost when encoded on expression vectors and that acquisition of natural plasmid-borne mcr-1 does not impair fitness in E. coli J53 but negatively influences growth rates in K. pneumoniae PRZ. PMID- 29180280 TI - Association between augmented renal clearance, antibiotic exposure and clinical outcome in critically ill septic patients receiving high doses of beta-lactams administered by continuous infusion: a prospective observational study. AB - This study assessed whether augmented renal clearance (ARC) impacts negatively on antibiotic concentrations and clinical outcomes in patients treated by high-dose beta-lactams administered continuously. Over a 9-month period, all critically ill patients without renal impairment treated by one of the monitored beta-lactams for a documented infection were eligible. During the first 3 days of antibiotic therapy, every patient underwent 24-h CLCr measurements and therapeutic drug monitoring. The main outcome was the rate of beta-lactam underdosing, defined as a free drug concentration <4 * MIC of the known pathogen. Secondary outcomes were rates of subexposure for beta-lactams and therapeutic failure. The performance of CLCr in predicting underdosing was assessed by a ROC curve, and multivariable logistic regression was performed to determine risk factors for subexposure and therapeutic failure. A total of 79 patients were included and 235 samples were analysed. The rate of underdosing<4*MIC was 12%, with a significant association with CLCr (P <0.0001). A threshold of CLCr >= 170 mL/min had a sensitivity and specificity of 0.93 (95% CI 0.77-0.99) and 0.65 (95% CI 0.58-0.71) for predicting beta-lactam underdosing<4*MIC. Mean CLCr values >=170 mL/min were significantly associated with subexposure<4xMIC [OR = 10.1 (2.4-41.6); P = 0.001]. Patients with subexposure<4*MIC presented higher rates of therapeutic failure [OR = 6.3 (1.2-33.2); P = 0.03]. Mean CLCr values >=170 mL/min remain a risk factor for subexposure to beta-lactams despite high doses of beta-lactams administered continuously. beta-Lactam subexposure was associated with higher rates of therapeutic failure in septic critically ill patients.

AB - Resistance among Klebsiella pneumoniae to the last-resort antibiotics carbapenems and colistin is increasing worldwide. In this study, whole-genome sequencing was used to determine the colistin resistance mechanisms in clinical isolates of carbapenem- and colistin-resistant K. pneumoniae from Vietnam. Alterations in the regulatory gene mgrB, via mutations and insertion sequence transpositions, were found in 30 of 31 isolates, emphasising the importance of this resistance mechanism in colistin-resistant K. pneumoniae. PMID- 29180282 TI - Antibiotic resistance genes in phage particles isolated from human faeces and induced from clinical bacterial isolates. AB - Phage particles have emerged as elements with the potential to mobilise antibiotic resistance genes (ARGs) in different environments, including the intestinal habitat. This study aimed to determine the occurrence of ARGs in phage particles present in faecal matter and induced from strains isolated from faeces. Nine ARGs (blaTEM, blaCTX-M-1 group, blaCTX-M-9 group, blaOXA-48, qnrA, qnrS, mecA, sul1 and armA) were quantified by qPCR in the phage DNA fractions of 150 faecal samples obtained from healthy individuals who had not received antibiotic treatment or travelled abroad in the 3 months prior to sample collection. On the suspicion that the detected particles originated from bacterial flora, 82 Escherichia coli and Klebsiella pneumoniae isolates possessing at least one identified ARG (blaTEM, blaCTX-M-1 group, blaCTX-M-9 group, armA, qnrA, qnrS and sul1) were isolated and their capacity to produce phage particles carrying these ARGs following induction was evaluated. Of 150 samples, 72.7% were positive for at least one ARG, with blaTEM and blaCTX-M-9 group being the most prevalent and abundant. Of the 82 isolates, 51 (62%) showed an increase in the number of copies of the respective ARG in the phage fraction following induction, with blaTEM, blaCTX-M-1 group, blaCTX-M-9 group and sul1 being the most abundant. Phages induced from the isolates were further purified and visualised using microscopy and their DNA showed ARG levels of up to 1010 gene copies/mL. This study highlights the abundance of phage particles harbouring ARGs and indicates that bacterial strains in the intestinal habitat could be source of these particles. PMID- 29180283 TI - Current Readings on Surgery for the Neonate With Hypoplastic Aortic Arch. AB - Aortic arch hypoplasia is commonly present in neonates born with ductal-dependent coarctation of the aorta. The ideal surgical repair of neonates with proximal arch hypoplasia continues to be debated. Controversy exists about the fate of the hypoplastic proximal aortic arch following surgical repair and whether that will eventually grow to normal size upon relief of the distal obstruction or will persist as a residual lesion that can affect the long-term outlook of those patients. There is new evidence that residual proximal arch hypoplasia and the shape of the reconstructed arch both have an important impact on vascular remodeling and on the subsequent development of hypertension. Those concerns about late outcomes despite what was originally deemed a successful repair in infancy, coupled with improved cardiopulmonary bypass and cerebral perfusion techniques that allow surgeons to address proximal arch hypoplasia with low morbidity, have rekindled the debate on how to address proximal arch hypoplasia, with the aim to offer a neonatal surgery that would last for a lifetime and provide both optimal early recovery and late freedom from hypertension and related complications. PMID- 29180284 TI - Reoperative Pulmonary Endarterectomy: Past Failures of Patient Selection Can Assist in Future Practice of Informed Consent. AB - The Pavia group reports their experience with reoperative pulmonary endarterectomy for patients with chronic thromboembolic pulmonary hypertension. They achieved impressive results in terms of hemodynamic parameters and functional status; however, a mortality rate of 40% represents inappropriate patient selection. Recommendations are made for identifying ideal operative candidates. PMID- 29180285 TI - Hsc70 regulates the IRES activity and serves as an antiviral target of enterovirus A71 infection. AB - Enterovirus A71 (EV-A71) is a small positive-stranded RNA virus that causes human hand, foot and mouth disease (HFMD) and fatal neurological disorders in some cases without effective treatment. Here we show that heat shock cognate protein 70 (Hsc70), a molecular chaperone, displays pivotal role in viral infections. Knockdown of Hsc70 significantly suppresses viral replication evidenced by reducing not only the level of both viral replication intermediates (negative stranded RNA) and viral genomic RNA (positive stranded RNA), but also the level of viral protein expression; whereas ectopic expression of Hsc70 markedly promotes viral replication. Interestingly, depletion of Hsc70 decreases the IRES activity of EV-A71, and the ectopic expression of Hsc70 enhances the IRES activity accordingly. Further study shows that Hsc70 binds viral genomic RNA but does not directly interact with IRES. Moreover, we reveal that Hsc70 interacts with 2A protease and promotes eIF4G cleavage. More importantly, Hsc70 inhibitor Ver-155008 significantly protects cytopathic effects from EV-A71 infection and inhibits both IRES activity and viral reproduction in a dose-dependent manner. The cell viability assay shows that the IC50 and CC50 are 2.01 MUM and 47.67 MUM, respectively. These results demonstrate not only an important mechanism of Hsc70 in facilitating EV-A71 replication, but also a target for antiviral drug development. PMID- 29180286 TI - The estimation of oxime efficiency is affected by the experimental design of phosphylated acetylcholinesterase reactivation. AB - Reactivation of acetylcholinesterase (AChE), an essential enzyme in neurotransmission, is a key point in the treatment of acute poisoning by nerve agents and pesticides, which structurally belong to organophosphorus compounds (OP). Due to the high diversity of substituents on the phosphorous atom, there is a variety of OP-AChE conjugates deriving from AChE inhibition, and therefore not only is there no universal reactivator efficient enough for the most toxic OPs, but for some nerve agents there is still a lack of any reactivator at all. The endeavor of many chemists to find more efficient reactivators resulted in thousands of newly-designed and synthesized oximes-potential reactivators of AChE. For an evaluation of the oximes reactivation efficiency, many research groups employ a simple spectrophotometric Ellman method. Since parameters that describe reactivator efficiency are often incomparable among laboratories, we tried to emphasize the critical steps in the determination of reactivation parameters as well as in the experimental design of a reactivation assay. We highlighted the important points in evaluation of reactivation kinetic parameters with an aim to achieve better agreement and comparability between the results obtained by different laboratories and overall, a more efficient evaluation of in vitro reactivation potency. PMID- 29180287 TI - Role of N-acetyltransferase 2 acetylation polymorphism in 4, 4'-methylene bis (2 chloroaniline) biotransformation. AB - Arylamine N-acetyltransferase 1 (NAT1) and 2 (NAT2) catalyze the acetylation of arylamine carcinogens. Single nucleotide polymorphisms in the NAT2 coding exon present in NAT2 haplotypes encode allozymes with reduced N-acetyltransferase activity towards the N-acetylation of arylamine carcinogens and the O-acetylation of their N-hydroxylated metabolites. NAT2 acetylator phenotype modifies urinary bladder cancer risk following exposures to arylamine carcinogens such as 4 aminobiphenyl. 4, 4'-methylene bis (2-chloroaniline) (MOCA) is a Group 1 carcinogen for which a role of the NAT2 acetylation polymorphism on cancer risk is unknown. We investigated the role of NAT2 and the genetic acetylation polymorphism on both MOCA N-acetylation and N-hydroxy-MOCA O-acetylation. MOCA N acetylation exhibited a robust gene dose response in rabbit liver cytosol and in cryopreserved human hepatocytes derived from individuals of rapid, intermediate and slow acetylator NAT2 genotype. MOCA exhibited about 4-fold higher affinity for recombinant human NAT2 than NAT1. Recombinant human NAT2*4 (reference) and 15 variant recombinant human NAT2 allozymes catalyzed both the N-acetylation of MOCA and the O-acetylation of N-hydroxy-MOCA. Human NAT2 5, NAT2 6, NAT2 7 and NAT2 14 allozymes catalyzed MOCA N-acetylation and N-hydroxy-O-acetylation at rates much lower than the reference NAT2 4 allozyme. In conclusion, our results show that NAT2 acetylator genotype has an important role in MOCA metabolism and suggest that risk assessments related to MOCA exposures consider accounting for NAT2 acetylator phenotype in the analysis. PMID- 29180288 TI - Study of potential transfer of aluminum to the brain via the olfactory pathway. AB - Many employees in the aluminum industry are exposed to a range of aluminum compounds by inhalation, and the presence of ultrafine particles in the workplace has become a concern to occupational health professionals. Some metal salts and metal oxides have been shown to enter the brain through the olfactory route, bypassing the blood-brain barrier, but few studies have examined whether aluminum compounds also use this pathway. In this context, we sought to determine whether aluminum was found in rat olfactory bulbs and whether its transfer depended on physicochemical characteristics such as solubility and granulometry. Aluminum salts (chloride and fluoride) and various nanometric aluminum oxides (13nm, 20nm and 40-50nm) were administered to rats by intranasal instillation through one nostril (10MUg Al/30MUL for 10days). Olfactory bulbs (ipsilateral and contralateral relative to instilled nostril) were harvested and the aluminum content was determined by graphite furnace atomic absorption spectrometry after tissue mineralization. Some transfer of aluminum salts to the central nervous system via the olfactory route was observed, with the more soluble aluminum chloride being transferred at higher levels than aluminum fluoride. No cerebral translocation of any of the aluminas studied was detected. PMID- 29180289 TI - Synthesis and antimalarial activity of 3'-trifluoromethylated 1,2,4-trioxolanes and 1,2,4,5-tetraoxane based on deoxycholic acid. AB - A series of new steroidal peroxides - 3'-trifluoromethylated 1,2,4-trioxolanes and 1,2,4,5-tetraoxanes based on deoxycholic acid were prepared via the reactions of the Griesbaum coozonolysis and peroxycondensation, respectively. 1,2,4 Trioxolanes were synthesized by the interaction of methyl O-methyl-3-oximino 12alpha-acetoxy-deoxycholate with CF3C(O)CH3 or CF3C(O)Ph and O3 as the mixtures of four possible stereoisomers at ratios of 1:2:2:1 and in yields of 50% and 38%, respectively. The major diastereomer of methyl 12alpha-acetoxy-5beta-cholan-24 oate-3-spiro-5'-(3'-methyl-3'-trifluoromethyl-1',2',4'-trioxolane) was isolated via crystallization of a mixture of stereoisomers from hexane and its (3S,3'R) configuration was determined using X-ray crystallographic analysis. Peroxycondensation of methyl 3-bishydroperoxy-12alpha-acetoxy-deoxycholate with CF3C(O)CH3 or acetone led to 1,2,4,5-tetraoxanes in yields of 44% and 37%, respectively. Antimalarial activity of these new steroidal peroxides was evaluated in vitro against the chloroquine-sensitive (CQS) T96 and chloroquine resistant (CQR) K1 strains of Plasmodium falciparum. Deoxycholic acid 3' trifluoromethylated 1,2,4,5-tetraoxane demonstrated a good IC50 value against CQR strain (IC50 (K1) = 7.6 nM) of P. falciparum. Tetraoxane with the acetone subunit demonstrated the best results among all tested peroxides with an IC50 value of 3 nM against the CQ-resistant K1 strain. In general, 1,2,4-trioxolanes of deoxycholic acid are less active than 1,2,4,5-tetraoxanes. PMID- 29180291 TI - Fish antimicrobial peptides (AMP's) as essential and promising molecular therapeutic agents: A review. AB - Antimicrobial peptides (AMPs) are generally considered as an essential component of innate immunity, thereby providing the first line of defense against wide range of pathogens. In addition, they can also kill the pathogens which are generally resistant to number of antibiotics, thereby providing the avenues for the development of future therapeutic agents. Fishes are constantly challenged by variety of pathogens which not only shows detrimental effect on their health but also increases risk of becoming resistant to conventional antibiotics. As fishes rely more on innate immunity, AMPs can serve as a potential defensive weapons in fishes for combating emerging devastating diseases. Generally, AMPs show multidimensional properties like rapid diffusion to the site of infection, recruitment of other immune cells to infected tissues and vigorous potential to rapidly neutralize broad range of pathogens (bacterial, fungal and viral). AMPs also exhibit diverse biological effect like endotoxin neutralization, immunomodulation and induction of angiogenesis in mammals. Due to these properties AMPs have become one of the most promising therapeutic agents to be studied. Till date, many AMPs have been isolated from the fishes but not fully characterized at molecular level. This review provides an overview of the structures, functions, and putative mechanisms of major families of fish AMPs. Further, we also highlighted how fish AMPs can be used as a novel therapeutic tool which is the theme of future research in drug development. PMID- 29180292 TI - NLRP3 inflammasome activation by mycobacterial ESAT-6 and dsRNA in intraocular tuberculosis. AB - The molecular basis of intraocular tuberculosis (TB) is not well understood. In this study, we investigated the role of two constituents of viable Mycobacterium tuberculosis - Early Secreted Antigenic Target-6 (ESAT-6), and mycobacterial RNA- in inflammasome activation in the retinal pigment epithelium (RPE), a key site of inflammation in intraocular TB. We found that ESAT-6 induced caspase-1 activation and inflammasome priming in mouse RPE cells, substantially more in wild-type than in Tlr2/3/4/7/9-/-, Myd88-/- or Nlrp3-/- RPE cells. Sub-retinal ESAT-6 injection resulted in greater RPE degeneration in wild-type than in Nlrp3-/- mice. In human ocular TB tissue sections, NLRP3 staining was noted in retina as well as RPE. Mycobacterial RNA, specifically its double stranded component, also induced caspase-1 activation, and the double stranded RNA was immunolocalized to human ocular TB sections. Our observations suggest that inflammasome activation in RPE by viable M. tuberculosis could potentially contribute to human intraocular TB. PMID- 29180293 TI - Development of indirect immunofluorescence assay for TCID50 measurement of grass carp reovirus genotype II without cytopathic effect onto cells. AB - Grass carp reovirus (GCRV) caused severe hemorrhagic disease with significant losses of fingerling and yearling grass carp, Cyenopharyngodon idellus, in southeast Asian. It was first isolated in 1983 in China, and clade analysis of the different GCRV isolates indicates there are at least three different genotypes I, II, and III. In recent years, GCRV genotype II has been determined as a dominant virus type which cause severe obvious clinical signs in fish but no cytopathic effect onto presently available cell culture. TCID50 is one of standard method to quantity infectious virus particles. In the present study, an indirect immunofluorescence assay (IFA) was developed using antibody against a protein encoded by segment 10 of GCRV genotype II. Moreover, the specific assay to differentitate GCRV of different genotypes and a sensitive assay for determination of GCRV genotype II were developed respectively. The results showed the IFA only can recognize genotype II virus at the lowest initial concentration of 550 genomic copies/ml. Furthermore, comparison of results obtained from qPCR and the TCID50 assay combined IFA was conducted. The results indicated that TCID50 of GCRV isolates JX0901 and HZ08 differs with 2 log steps reduction in the numbers of viruses compared with the number of genome copies detected by qPCR. The immunofluorescence assay developed is sensitive, specific, and the TCID50 combined with IFA will be a standardizable technique for the quantitation and detection of infectious GCRV in cell culture without cytolysis. PMID- 29180290 TI - Estradiol and the control of feeding behavior. AB - This review lays out the evidence for the role of E2 in homeostatic and hedonic feeding across several species. While significant effort has been expended on homeostatic feeding research, more studies for hedonic feeding need to be conducted (i.e. are there increases in meal size and enhanced motivation to natural food rewards). By identifying the underlying neural circuitry involved, one can better delineate the mechanisms by which E2 influences feeding behavior. By utilizing more selective neural targeting techniques, such as optogenetics, significant progress can be made toward this goal. Together, behavioral and physiological techniques will help us to better understand neural deficits that can increase the risk for obesity in the absence of E2 (menopause) and aid in developing therapeutic strategies. PMID- 29180296 TI - Universal Lipid Screening in 9- to 11-Year-Olds Before and After 2011 Guidelines. AB - OBJECTIVE: To determine whether the 2011 guidelines for universal routine screening for dyslipidemia in children aged 9 to 11 years, published by the Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents and National Heart, Lung, and Blood Institute, are being followed by pediatric primary-care providers. METHODS: Retrospective data were obtained for 63,951 well-child visits (WCV) in children aged 9 to 11 years from 2 health care systems and 1 insurance program from 2009 to 2015. The proportion of WCV that had a lipid panel or total cholesterol test performed within 1 year of the visit was compared for 2009-2011 versus 2013-2015. Associations between demographic variables and lipid screening were evaluated with logistic regression. The frequency of tested children who had abnormal lipid results was evaluated. RESULTS: Only 3.5% of 9- to 11-year WCV had lipid tests performed in association with the visit before and after the guidelines. Of those tested, 43% had an abnormal lipid result. CONCLUSIONS: Utah clinicians rarely follow guidelines for universal lipid screening of children aged 9 to 11. This represents a missed opportunity to identify children at risk for early-onset cardiovascular disease. PMID- 29180295 TI - Antimicrobial and bactericidal impacts of Bacillus amyloliquefaciens CECT 5940 on fecal shedding of pathogenic bacteria in dairy calves and adult dogs. AB - Two experiments were carried out to evaluate the bactericidal impacts of Bacillus amyloliquefaciens CECT 5940 on the shedding of faecal pathogenic bacteria in dairy calves (Experiment 1) and in adults dogs (experiment 2). In the calves experiment, a completely randomized design was used to investigate the faecal bacteria profile of Holstein dairy calves fed with either pasteurized waste milk (PWM; n = 9) or a formulated non-medicated milk replacer (NMR; n = 9) for 60 d. The NMR containing sodium-butyrate and the active probiotic B. amyloliquefaciens CECT 5940. In the dogs experiment, addition of same probiotic (i.e., B. amyloliquefaciens CECT 5940) was carried out in two stages. The first stage started from day 7-37, and the second from day 44-71. The assessment of faecal score measured on day 22, 37, 42, 57, 71 and 77 to determine the texture of the stools. Calves received PWM consumed (P < 0.05) more starter feed between day 16 and day 45. The calves fed NMR had more moisture faeces and less cough reflux than the PWM-calves. Feeding NMR to calves increased faecal Klebsiella oxytoca and Proteus vulgaris counts in comparison to PWM-calves. The administration of B. amyloliquefaciens CECT 5940 to the dog diet has no significant effect on the hardness of the stool. Meanwhile, the bacillus count increases while the coliforms count decreases upon B. amyloliquefaciens CECT 5940 administration. This reveals that B. amyloliquefaciens CECT 5940 survived the gastrointestinal passage and rapidly colonized the dog intestine, which could positively affect the metabolism and composition of the intestinal microflora. These results show that B. amyloliquefaciens are a promising probiotic with an antimicrobial and bactericidal activities against the intestinal pathogenic bacteria for dairy calves and adult dogs. PMID- 29180294 TI - Homeopathic treatment as an alternative prophylactic to minimize bacterial infection and prevent neonatal diarrhea in calves. AB - Bovine neonatal diarrhea is common due low immunity in newborn calves, poor management (or absence) of sanitary barriers, and other factors. Newborn calves with diarrhea in the first days of life suffer failure to thrive and may die if left untreated. The aim of this study was to evaluate whether prophylactic administration of a homeopathic product (Dia 100(r)) can control bovine neonatal diarrhea in calves born on a farm with substantial sanitary challenges. We counted total bacteria and protozoan parasites in fecal samples. We measured serum glucose, total protein, globulin, albumin, cholesterol and triglycerides on days 1, 7 and 14 of life. Twenty newborn calves were maintained in individual stalls, and were divided in two groups: ten untreated animals (control) and ten animals treated with Dia 100(r). Fecal consistency was evaluated daily. We diagnosed diarrhea in five animals in the treated group, and in all animals from the control group. Infections with Escherichia coli and Giardia duodenalis were identified as the responsible organisms. The E. coli count was low in the treatment group on day 7 of life compared with the control group. Antibiotics were given to eight animals in the control group, and to two animals in the treatment group. On day of life 7, serum levels of total protein and globulins were higher in the control group, but were lower on day 14. Serum levels of glucose and triglycerides were greater in treated animals on days 7 and 14, suggesting that the homeopathic product contributes to improvement of intestinal health and absorption and nutrients. We conclude that Dia 100(r) controls diarrhea with 50% of efficacy, and reduces antibiotic utilization.

PMID- 29180298 TI - Overexpressing cell systems are a competitive option to primary adipocytes when predicting in vivo potency of dual GPR81/GPR109A agonists. AB - Mathematical models predicting in vivo pharmacodynamic effects from in vitro data can accelerate drug discovery, and reduce costs and animal use. However, data integration and modeling is non-trivial when more than one drug-target receptor is involved in the biological response. We modeled the inhibition of non esterified fatty acid release by dual G-protein-coupled receptor 81/109A (GPR81/GPR109A) agonists in vivo in the rat, to estimate the in vivo EC50 values for 12 different compounds. We subsequently predicted those potency estimates using EC50 values obtained from concentration-response data in isolated primary adipocytes and cell systems overexpressing GPR81 or GPR109A in vitro. A simple linear regression model based on data from primary adipocytes predicted the in vivo EC50 better than simple linear regression models based on in vitro data from either of the cell systems. Three models combining the data from the overexpressing cell systems were also evaluated: two piecewise linear models defining logical OR- and AND-circuits, and a multivariate linear regression model. All three models performed better than the simple linear regression model based on data from primary adipocytes. The OR-model was favored since it is likely that activation of either GPR81 or GPR109A is sufficient to deactivate the cAMP pathway, and thereby inhibit non-esterified fatty acid release. The OR-model was also able to predict the in vivo selectivity between the two receptors. Finally, the OR-model was used to predict the in vivo potency of 1651 new compounds. This work suggests that data from the overexpressing cell systems are sufficient to predict in vivo potency of GPR81/GPR109A agonists, an approach contributing to faster and leaner drug discovery. PMID- 29180299 TI - Initial Imaging for Pediatric Renal Tumors: An Opportunity for Improvement. AB - PURPOSE: Current Children's Oncology Group studies on renal malignancy focus on minimizing treatment side effects with a goal of decreasing long-term complications. In this series we evaluate the patterns of initial imaging in children with renal tumors. MATERIALS AND METHODS: We retrospectively reviewed records of 122 patients treated for renal tumors at our institution between 2005 and 2016. Ideal imaging was defined as cross-sectional imaging of the chest, abdomen and pelvis in a single setting without any additional ionizing radiation exposing scans. RESULTS: Median patient age was 33.5 months (range 1 to 195). A total of 101 patients (83%) were initially evaluated elsewhere and subsequently referred to oncology (67.2%) for further evaluation. Before treatment 58 patients (47.5%) underwent imaging that was obtained in an ideal manner. Compared to those undergoing ideal imaging, median additional radiation exposure was 2.31 mSv (range 0.9 to 11.5), 3.08 mSv (0.6 to 11.7) and 5.1 mSv (1.2 to 16) in patients younger than 5 years, 5 to 9 years old and 10 years or older, respectively. Factors associated with undergoing ideal imaging included undergoing abdominal ultrasound as an initial scan (OR 3.637, p = 0.001), while presentation to an emergency department resulted in a reduced likelihood of undergoing ideal imaging (OR 0.351, p = 0.012). Factors associated with a decreased likelihood of undergoing initial screening ultrasound included presenting with vague symptoms (OR 0.072, p = 0.045) and presenting to a tertiary care emergency department (OR 0.228, p = 0.027). CONCLUSIONS: Current patterns of initial imaging for pediatric renal tumors are often associated with unnecessary and avoidable imaging studies, resulting in increased radiation exposure. Presenting to the emergency room as the initial point of contact with vague symptoms is associated with a decreased likelihood of undergoing appropriate or ideal pretherapy imaging, while initial evaluation with ultrasound is associated with a greater likelihood of undergoing ideal imaging, reducing overall radiation exposure. We advocate initial abdominal ultrasound in all pediatric patients suspected of having an abdominal mass. Our data highlight an opportunity for quality improvement across specialties caring for children with renal tumors. PMID- 29180300 TI - Variation in Spending around Surgical Episodes of Urinary Stone Disease: Findings from Michigan. AB - PURPOSE: To help rein in surgical spending there is growing interest in the application of payment bundles to common outpatient procedures like ureteroscopy and shock wave lithotripsy. However, before urologists can move to such a payment system they need to know where episode costs are concentrated. MATERIALS AND METHODS: Using claims data from Michigan Value Collaborative we identified patients who underwent ureteroscopy or shock wave lithotripsy at hospitals in Michigan from 2012 to 2015. We then totaled expenditures for all relevant services during the 30-day surgical episodes of these patients and categorized component payments (ie those for the index procedure, subsequent hospitalizations, professional services and postacute care). Finally we quantified the variation in total episode expenditures for ureteroscopy and shock wave lithotripsy across hospitals, examining drivers of this variation. RESULTS: A total of 9,449 ureteroscopy and 6,446 shock wave lithotripsy procedures were performed at 62 hospitals. Among these hospitals there was threefold variation in ureteroscopy and shock wave lithotripsy spending. The index procedure accounted for the largest payment difference between high vs low cost hospitals (ureteroscopy $7,936 vs $4,995 and shock wave lithotripsy $4,832 vs $3,207, each p <0.01), followed by payments for postacute care (ureteroscopy $2,207 vs $1,711 and shock wave lithotripsy $2,138 vs $1,104, each p <0.01). Across hospitals the index procedure explained 68% and 44% of the variation in episode spending for ureteroscopy and shock wave lithotripsy, and postacute care payments explained 15% and 28%, respectively. CONCLUSIONS: There exists substantial variation in ambulatory surgical spending across Michigan hospitals for urinary stone episodes. Most of this variation can be explained by payment differences for the index procedure and for postacute care services. PMID- 29180301 TI - When should ADULT CPR be delivered to children?

PMID- 29180303 TI - Effects of erythropoietin on astrocytes and brain endothelial cells in primary culture during anoxia depend on simultaneous signaling by other cytokines and on duration of anoxia. AB - Studies on animals revealed neuroprotective effects of exogenously applied erythropoietin (EPO) during cerebral ischemia/hypoxia. Yet, application of exogenous EPO in stroke patients often lead to haemorrhagic transformation. To clarify potential mechanism of this adverse effect we explored effects of EPO on viabilities of astrocytes and brain endothelial cells (BECs) in primary culture during anoxia of various durations, in the presence or absence of vascular endothelial growth factor (VEGF) and angiopoietin-1 (Ang1), which are cytokines that are also released from the neurovascular unit during hypoxia. Anoxia (2-48 h) exerted marginal effects on BECs' viability and significant reductions in viability of astrocytes. Astrocyte-conditioned medium did not exert effects and exerted detrimental effects on BECs during 2 h and 24 h anoxia, respectively. This was partially reversed by inhibition of Janus kinase (Jak)2/signal transducer and activator of transcription (STAT)5 activation. Addition of rat recombinant EPO (rrEPO) during 2 h-6h anoxia was protective for astrocytes, but had no effect on BECs. Addition of rrEPO significantly reduced viability of BECs and astrocytes after 48 h anoxia and after 24 h-48 h anoxia, respectively, which was attenuated by inhibition of Jak2/STAT5 activation. Simultaneous addition of rrEPO and VEGFA (1-165) caused marginal effects on BECs, but a highly significant protective effects on astrocytes during 24-48 h anoxia, which were attenuated by inhibition of Jak2/STAT5 activation. Simultaneous addition of EPO, VEGFA 1-165 and Ang1 exerted protective effects on BECs during 24 h-48 h anoxia, which were attenuated by addition of soluble Tie2 receptor. These data revealed that EPO could exert protective, but also injurious effects on BECs and astrocytes during anoxia, which depended on the duration of anoxia and on simultaneous signaling by VEGF and Ang1. If these injurious effects occur in stroke patients, they could enhance vascular damage and haemorrhagic transformation. PMID- 29180305 TI - Pulmonary Vascular Resistance During Exercise Predicts Long-Term Outcomes in Heart Failure With Preserved Ejection Fraction. AB - BACKGROUND: In heart failure with preserved ejection fraction (HFpEF), the prognostic value of pulmonary vascular dysfunction (PV-dysfunction), identified by elevated pulmonary vascular resistance (PVR) at peak exercise, is not completely understood. We evaluated the long-term prognostic implications of PV dysfunction in HFpEF during exercise in consecutive patients undergoing invasive cardiopulmonary exercise testing for unexplained dyspnea. METHODS: Patients with HFpEF were classified into 2 main groups: resting HFpEF (n = 104, 62% female, age 61 years) with a pulmonary arterial wedge pressure (PAWP) >15 mmHg at rest; and exercise HFpEF (eHFpEF; n = 81) with a PAWP <15 mmHg at rest, but >20 mmHg during exercise. The eHFpEF group was further subdivided into eHFpEF + PV-dysfunction (peak PVR >=80 dynes/s/cm-5; n = 55, 60% female, age 64) group and eHFpEF - PV dysfunction (peak PVR <80 dynes/s/cm-5; n = 26, 42% female, age 54 years) group. Outcomes were analyzed for the first 9 years of follow-up and included any cause mortality and heart failure (HF)-related hospitalizations. The mean follow-up time was 6.7 +/- 2.6 years (0.5-9.0). RESULTS: Mortality rate did not differ among the groups. However, survival free of HF-related hospitalization was lower for the eHFpEF + PV-dysfunction group compared with eHFpEF - PV-dysfunction (P = .01). These findings were similar between eHFpEF + PV-dysfunction and the resting HFpEF group (P = .774). By Cox analysis, peak PVR >=80 dynes/s/cm-5 was a predictor of HF-related hospitalization for eHFpEF (hazard ratio 5.73, 95% confidence interval 1.05-31.22, P = .01). In conclusion, the present study provides insight into the impact of PV-dysfunction on outcomes of patients with exercise-induced HFpEF. An elevated peak PVR is associated with a high risk of HF related hospitalization. PMID- 29180306 TI - Intraoperative Effect of Preoperative Gonadotropin-Releasing Hormone Analogue Administration in Women Undergoing Cold Loop Hysteroscopic Myomectomy: A Randomized Controlled Trial. AB - STUDY OBJECTIVE: To evaluate the intraoperative effects of gonadotropin-releasing hormone (GnRH) analogue pretreatment in patients undergoing cold loop hysteroscopic myomectomy. DESIGN: Randomized controlled trial (Canadian Task Force classification I). SETTING: Arbor Vitae Center for Endoscopic Gynecology, Rome, Italy. PATIENTS: A total of 99 patients were randomized and subsequently allocated to the GnRH analogue group or to the nonpharmacologic treatment control group. Fifteen patients were lost after allocation, and 42 patients per group underwent hysteroscopic myomectomy. INTERVENTIONS: Cold loop hysteroscopic myomectomy. MEASUREMENTS AND MAIN RESULTS: The control group accomplished the treatment in a 1-step procedure more frequently than the GnRH analogue group (92.85% and 73.8% of cases, respectively; p = .040). The completion of the treatment was more unlikely in case of G2 myomas (p = .006), whereas no differences were recorded for G1 and G0 myomas. The multivariate analysis showed a significant correlation between the multiple-step treatment and the use of GnRH analogue (odds ratio, 5.365; 95% confidence interval [CI], 1.018-28.284; p = .048), grading (odds ratio, 4.503; 95% CI, 1.049-19.329; p = .043), and size of myomas (odds ratio, 1.128; 95% CI, 1.026-1.239; p = .013). CONCLUSIONS: Preoperative GnRH analogue administration did not facilitate the completion of cold loop hysteroscopic myomectomy in a single surgical procedure in G2 myomas and was correlated with a longer duration of the surgery. No significant benefits were found for G0 and G1 myomas. (ClinicalTrials.gov: NCT01873378.). PMID- 29180304 TI - Functional analysis of corin protein domains required for PCSK6-mediated activation. AB - Atrial natriuretic peptide (ANP) is a cardiac hormone essential for normal blood pressure and cardiac function. Corin is a transmembrane serine protease that activates ANP. Recently, we identified proprotein convertase subtilisin/kexin-6 (PCSK6), also called PACE4, as the long-sought corin activator. Both corin and PCSK6 are expressed in cardiomyocytes, but corin activation occurs only on the cell surface. It remains unknown if cell membrane association is needed for PCSK6 to activate corin. Here we expressed corin deletion mutants in HEK293 cells to analyze the domain structures required for PCSK6-mediated activation. Our results show that soluble corin lacking the transmembrane domain was activated by PCSK6 in the conditioned medium but not intracellularly. Recombinant PCSK6 also activated the soluble corin under cell-free conditions. Moreover, PCSK6-mediated corin activation was not enhanced by cell membrane fractions. These results indicate that cell membrane association is unnecessary for PCSK6 to activate corin. Experiments with monensin that blocks PCSK6 secretion and immunostaining indicated that the soluble corin and PCSK6 were secreted via different intracellular pathways, which may explain the lack of corin activation inside the cell. We also found that the protein domains in the corin pro-peptide region were dispensable for PCSK6-mediated activation and that addition of heparan sulfate and chondroitin sulfate or treatment with heparinase or chondroitinase did not alter corin activation by PCSK6 in HEK293 cells. Together, our results provide important insights into the molecular and cellular mechanisms underlying PCSK6 mediated corin activation that is critical for cardiovascular homeostasis. PMID- 29180307 TI - Laparoscopic Sterilization Under Local Anesthesia with Conscious Sedation Versus General Anesthesia: Systematic Review of the Literature. AB - Female sterilization is the most popular and common contraceptive method worldwide. Because hysteroscopic sterilization techniques are used less often due to side effects, the number of laparoscopic sterilization is increasing. A systematic overview concerning the most optimal anesthetic technique for laparoscopic sterilization is lacking. We performed a systematic review to compare conscious sedation with general anesthesia for laparoscopic sterilization procedures with respect to clinical relevant outcome measures, such as operating times, perioperative parameters and complications, patient comfort, recovery, and patient satisfaction. We searched Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE for randomized controlled trials comparing general anesthesia with conscious sedation for laparoscopic sterilization. Two authors (AGH and HAAMvV) abstracted and entered data into RevMan. Methodologic quality of the included trials was critically appraised. For our main outcome measures mean differences (continuous variables) and risk ratios (dichotomous variables) with 95% confidence intervals using random-effect models were calculated. Four randomized controlled trials were included comparing general anesthesia versus local anesthesia with conscious sedation for laparoscopic sterilization. The methodologic quality of the studies was moderate to good. Both techniques were comparable with regard to operating times, complications, and postoperative pain. However, local anesthesia with conscious sedation showed better results compared with general anesthesia with respect to recovery times, patient complaints of sore throat, and patient recovery and satisfaction. In conclusion, this systematic review about anesthetic techniques for laparoscopic sterilization showed that both general anesthesia and conscious sedation have no major anesthetic complications and may therefore be safe. Patients might benefit from conscious sedation in terms of recovery times, sore throat, and patient recovery and satisfaction, but only a few studies are included in the review and are relatively old. New research regarding this subject is needed to advise our patients most optimally in the future about the best anesthetic technique to be used when choosing for a laparoscopic sterilization procedure.

PMID- 29180311 TI - Repeated Measurement of Fractional Exhaled Nitric Oxide Is Not Essential for Asthma Screening. AB - BACKGROUND AND OBJETIVE: Older guidelines recommend that fractional exhaled nitric oxide (FeNO) should be checked more than twice during the same session to confirm an asthma diagnosis. Recent studies show the excellent reproducibility of FeNO measurements. Objetive: We aimed to determine whether repeated FeNO measurements during the same session are necessary for asthma screening. MATERIAL AND METHODS: We retrospectively reviewed the electronic medical records of adult outpatients who visited the respiratory medicine department for diagnosis of asthma and assessed FeNO measurements obtained from June 2016 to July 2017. RESULTS: Of the 132 patients enrolled, 79 (59.8%) were diagnosed with asthma. Repeated FeNO measurements taken during the same session showed high reproducibility (intraclass correlation coefficient >0.9; P<.001) and a strong correlation (Pearson coefficient >0.9; P<.001), although reproducibility and correlation were slightly weaker in patients with low FeNO values. The value of repeated measurement was not significant; however, the second FeNO measurement was significantly higher than the first measurement in patients with the worst and best lung function. The predictive power of the first measurement of FeNO (sensitivity, 80.5%; specificity, 85.1%) was not inferior to the second (sensitivity, 76.6%; specificity 85.1%). The same was true of the geometric mean of the two. CONCLUSIONS: Repeated FeNO measurement during the same session is not essential for asthma screening in cases where the first acceptable FeNO measurement is performed using the proper method.

PMID- 29180316 TI - Dermoscopy and confocal microscopy for metachronous multiple melanomas: morphological, clinical, and molecular correlations. AB - Cutaneous melanoma is one of the most frequent malignancies of the skin in Caucasian populations. Patients who develop cutaneous melanoma are at increased risk of developing a second primary melanoma. The estimated incidence of multiple primary melanoma (MPM) ranges from 1.2% to 8.2% of cases, with a high preponderance of melanomas occurring metachronously. The aim of this study was to describe dermoscopic, microscopic, clinical, and molecular correlations between first and subsequent melanomas in patients with metachronous MPMs. Twenty-four paired melanomas from 12 MPM patients were evaluated for architectural characteristics based on dermoscopy and confocal microscopy, as well as for mutations in BRAF and NRAS genes by Sanger-based sequencing analysis. Specific scores used for classifying features of dermoscopy (global pattern; 7-point check list; ABCD Stolz score) and confocal microscopy (Segura and Pellacani) were compared with genetic and histological data. Consistency in dermoscopic patterns between the primary and subsequent cutaneous melanomas were observed in about two thirds of cases, whereas concordant features based on confocal microscopy were found in only about two fifths of cases. The majority of patients (7/12; 58%) presented consistent BRAF/NRAS mutation patterns between first and subsequent primary melanomas. A significant association between BRAF mutations and Pellacani score was evident. Similarities between the index melanoma and subsequent cutaneous melanomas were observed with regards to dermoscopic features and, to a much less extent, confocal microscopy findings. Our data further indicate that the Pellacani score may be used to predict BRAF mutations. PMID- 29180317 TI - A case series of paediatric and adolescent melanoma.

AB - OBJECTIVE: To investigate the role of long non-coding RNA growth arrest-specific transcript 5 (lncRNA-GAS5) in breast cancer progression and epithelial mesenchymal transition (EMT) of the cancer cells. METHODS: Real-time quantitative PCR (qRT-PCR) was used to detect the expression of lncRNA-GAS5 in 37 pairs of breast cancer and adjacent non-tumor tissues and in parental MCF-7 cells and paclitaxel-resistant MCF-7 (MCF-7/PR) cells, and the correlation of lncRNA-GAS5 expression with the clinical stage and lymph node metastasis of breast cancer was investigated. The expressions of the genes related with cell cycle and EMT at both the mRNA and protein levels were detected using qRT-PCR, Western blotting and immunohistochemistry. The changes in the biological behaviors and morphology of breast cancer cells with either lncRNA-GAS5 knockdown or overexpression were observed. Nude mouse models were established bearing breast cancer xenografts derived from MCF-7/PR cells or MCF-7/PR cells over-expressing lncRNA-GAS5, and the inhibitory effect of paclitaxel on tumor growth was evaluated. RESULTS: The transcriptional levels of lncRNA-GAS5 were significantly lower in breast cancer tissues than in the adjacent non-tumor tissues (P<0.05), and decreased lncRNA GAS5 expression was significantly correlated with TNM stage and lymph node metastasis of breast cancer (P<0.05). lncRNA-GAS5 expression was also significantly lowered in paclitaxel-resistant breast cancer cells and showed a positive correlation with P21 expression and a negative correlation with CDK6. MCF-7 cells during EMT presented with a lowered expression of lncRNA-GAS5, whereas lncRNA-GAS5 over-expression strongly suppressed MCF-7/PR cell migration and invasion, and increased the susceptibility of the cells to paclitaxel. In the tumor-bearing nude mouse models, lncRNA-GAS5 overexpression in the tumor cells obviously enhanced the inhibitory effect of paclitaxel on tumor growth and lung metastasis by reversing the EMT marker proteins. CONCLUSION: A decreased expression of lncRNA-GAS5 promotes lung metastasis of breast cancer by inducing EMT, suggesting the potential of lncRNA-GAS5 as a therapeutic target in breast cancer. PMID- 29180321 TI - [A recombinant adenovirus vector carrying murine interleukin-21 gene controls chronic HBV infection in mice]. AB - OBJECTIVE: To investigate the effect of an adenovirus vector containing murine interleukin-21 gene (Ad-GFP-mIL-21) in virus clearance and on the production of HBV-specific antibodies in mice with persistent HBV infection. METHODS: ELISA and Western blot analysis were used to detect the expression of mIL-21 in the supernatant and cytoplasm of cultured HepG2.2.15 cells after infection by Ad-GFP mIL-21. Mouse models of chronic HBV infection established by in vivo transduction with rAAV8-1.3HBV were divided into 3 groups for treatment 12 weeks later with injection of Ad-GFP-mIL-21, GFP recombinant adenovirus or PBS via the tail vein. Serum levels of HBsAg, HBsAb, HBcAb, and mIL-21 in the mice were detected using ELISA, and the expression of Ad-GFP-mIL-21 in the organs was observed by fluorescent microscopy at different time points after the injection. RESULTS: Ad GFP-mIL-21 was capable of infecting HepG2.2.15 cells in vitro, and the levels of mIL-21 in the supernatant were correlated with the titers of adenovirus administered and the infection time. In the mice with persistent HBV infection, green fluorescence expression was observed almost exclusively in the liver on day 4 after injection of Ad-GFP-mIL21, and serum levels of IL-21 increased significantly compared with the level before treatment (P<0.05). Although HBsAb was undetectable in both Ad-GFP-mIL21-injected and control mice on day 13, a significantly higher serum level of HBcAb was detected in the mice with Ad-GFP mIL21 injection (P<0.05). CONCLUSION: Ad-GFP-mIL-21 can efficiently express mIL 21 in mice with chronic HBV infection to downregulate serum levels of HBsAg and promote HBcAb production, suggesting its efficacy in controlling chronic HBV infection. PMID- 29180322 TI - [Peripheral blood T cell TNF-alpha and IFN-gamma production stimulated by low molecular peptide of Mycobacterium tuberculosis heat-resistant antigen for differential diagnosis between pulmonary tuberculosis and latent tuberculosis infection]. AB - OBJECTIVE: To investigate the effects of low molecular peptide of Mycobacterium tuberculosis heat-resistant antigen (Mtb-HAg-10k) on the production of tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma) in peripheral blood T cells and test the feasibility of differential diagnosis between pulmonary tuberculosis (PTB) and latent tuberculosis infection (LTBI) by assessing the number of Mtb-HAg-10k-stimulated IFN-gamma-producing T cells. METHODS: Peripheral blood mononuclear cells (PBMCs) were separated from the peripheral blood of 10 healthy adults, 6 individuals with LTBI and 13 patients with PTB. The PBMCs were cultured in the presence of Mtb-HAg-10k obtained by ultrafiltration centrifugation, with Mtb-HAg and phytohaemagglutinin (PHA) as the controls. The proportions of TNF-alpha- and IFN-gamma-producing cells in the T cell subsets were detected by flow cytometry (FCM), and the number of IFN-gamma producing cells from patients with PTB and LTBI was detected with ELISPOT. RESULTS: Flow cytometry showed that Mtb-HAg-10k exposure resulted in a significantly higher proportion of TNF-alpha-producing gammadeltaT cells than that of IFN-gamma-producing gammadeltaT cells in the PBMCs (P<0.01). Compared with the PBMCs exposed to PHA, the PBMCs exposed to Mtb-HAg-10k exhibited a significantly greater proportion of gammadeltaT cells that produced both TNF alpha and IFN-gamma (P<0.01) but a significantly lower proportion of alphabetaT cells producing both TNF-alpha and IFN-gamma (P<0.01). Mtb-HAg-10k exposure of the PBMCs caused a significant reduction in the number of IFN-gamma-producing cells as compared with Mtb-HAg and PHA treatments (P<0.01), and this reduction was more obvious in PBMCs from patients with PTB than in those from individuals with LTBI (P<0.01). CONCLUSION: Mtb-HAg-10k can markedly induce gammadeltaT cells in the PBMCs to produce TNF-alpha and IFN-gamma, and detection of the number of IFN-gamma-producing cells in the PBMCs following Mtb-HAg-10k stimulation helps in the differential diagnosis between pulmonary tuberculosis and latent tuberculosis infection. PMID- 29180323 TI - [Pathogen analysis in patients with diabetic foot osteomyelitis using 16S rRNA high-throughput sequencing]. AB - OBJECTIVE: To analyze the characteristics of pathogenic microorganisms in the infected bone tissues in patients with diabetic foot osteomyelitis (DFO) using 16S rRNA high-throughput sequencing to facilitate rapid and accurate detection of pathogens and effective infection control. METHODS: Between September, 2016 and April, 2017, 16 patients with DFO were admitted in our department and infected bone specimens were obtained during debridement. The pathogenic microorganisms in the specimens were identified using both 16S rRNA high-throughput sequencing and automatic blood culture analyzer, and the characteristics of the microflora were analyzed based on 16S rRNA sequencing data in comparison with the results of blood culture. RESULTS: The results of 16S rRNA sequencing showed that bone tissues of DFO contained diverse and uniformly distributed pathogenic organisms, among which 20 (87%) dominant genera were identified with Prevotella as the most abundant pathogen. Both 16S rRNA sequencing and routine culture results suggested the domination of gram-negative bacteria among the pathogens in DFO bone tissues. 16S rRNA sequencing, compared with routine culture, yielded a higher positivity rate (100% vs 88.24%) and detected a greater average number of pathogens (12.56 vs 1.50) and a higher proportion of gram-negative bacteria (67.16% vs 50.00%) in the samples. 16S rRNA sequencing detected nearly all the pathogens identified by routine culture except for Escherichia coli, Serratia marcescens and Enterobacter cloaca, and identified 13 genera that failed to be detected by routine culture, including the obligate or strict anaerobes Anaerococcus, Veillonella, Bacteroides, Fusobacterium, Porphyromonas, Finegoldia, Prevotella, Peptostreptococcus, Parvimonas, Peptoniphilus and Bulleidia. Routine culture did not detect any anaerobes in the samples but identified multidrug-resistant strains in as many as 58.33% of the pathogens. CONCLUSIONS: 16S rRNA high throughput sequencing is capable of demonstrating the diversity and abundance of microflora in DFO bone tissues, where diverse and uniformly distributed pathogens can be detected with a discrete distribution of the dominant genera, most of which are gram-negative. Compared with routine culture method, 16S rRNA sequencing allows more convenient and accurate identification of the pathogens (especially gram-negative bacteria and anaerobes), and can be useful in clinical decision on appropriate treatment of DFO. PMID- 29180324 TI - [Effects of simvastatin on aortic vascular endothelial cell apoptosis and Bcl-2 protein expression in a rat model of atherosclerosis]. AB - OBJECTIVE: To explore the effects of simvastatin on vascular endothelial cell apoptosis and Bcl-2 protein expression in the aorta in a rat model of atherosclerosis. METHODS: Thirty-six rats were randomized into control group (n=10), atherosclerosis model group (n=13) and simvastatin intervention group (n=13). In the latter two groups, rat models of atherosclerosis were established by intraperitoneal injection of vitamin D3 combined with high-fat feeding for 6 weeks, and the control rats were fed with regular diet. In the intervention group, the rats were further fed with high-fat diet with daily simvastatin treatment for 4 weeks. After the treatments, the pathological changes and plaque in the thoracic aorta were observed, and the expression of Bcl-2 protein was detected with immunohistochemistry. TUNEL assay was used to determine the apoptosis index (AI) of the vascular endothelial cells. RESULTS: Compared with that in the control group, Bcl-2 protein expression in the aorta of atherosclerotic rats was significantly decreased (P<0.05); simvastatin treatment obviously increased the expression of Bcl-2 protein in atherosclerotic rats (P<0.05) to a level similar to that in the control group. The AI was the highest in the model group (P<0.05) and comparable between the control and simvastatin treatment group. CONCLUSION: The therapeutic effect of simvastatin against atherosclerosis is probably mediated by up-regulation of Bcl-2 protein, which inhibits vascular endothelial cell apoptosis in rats with aortic atherosclerosis. PMID- 29180325 TI - [Correlation between ectopic fat accumulation and insulin sensitivity in obese individuals with different glucose tolerance levels]. AB - OBJECTIVE: To investigate the correlation between liver and skeletal muscle fat contents and insulin resistance in obese individuals with different levels of glucose tolerance. METHODS: RESULTS: Ten non-obese individuals with normal glucose tolerance (NGT), 9 obese individuals with NGT, and 7 obese individuals with impaired glucose tolerance (IGT) were enrolled in this study. All the participants were examined for insulin sensitivity by hyperinsulinemic-euglycemic clamp and for liver and skeletal muscle fat accumulation quantified by proton magnetic resonance spectroscopy (1H MRS). The data were collected from the subjects including somatometric measurements, fasting plasma glucose, 2-h plasma glucose (2hPG), fasting insulin, and blood biochemistry. Linear correlation analysis and multiple linear stepwise regression analysis were used to analyze the relationship between ectopic fat accumulation and insulin resistance. RESULTS: The glucose infusion rates (GIR, presented as the M value) differed significantly among IGT-obese (3.95?1.66 mg.kg-1.min-1), NGT-obese (6.14?1.90 mg.kg-1.min-1) and NGT-non-obese (8.78?2.46 mg.kg-1.min-1) groups (P<0.05). The 3 groups also showed significant differences in liver fat contents [(15.23?3.09)%, (6.25?0.38)%, and (1.89?0.90)%, respectively, P<0.05] and intramyocellular lipids in the tibialis anterior (2.69?0.95, 2.61?1.45, and 1.54?0.66 mmol/kg, respectively, P<0.05). Linear analysis revealed that liver fat content, but not skeletal muscle fat content, was significantly correlated with the M value. Multiple linear stepwise regression analysis using M value as the dependent variable (Y) revealed that liver fat content (X) was an independent factor inversely correlated with the M value (regression equation: Y=-30.562X+9.007, R2=0.717, P<0.01). CONCLUSIONS: Liver fat accumulation, but not skeletal muscle fat accumulation, is correlated with insulin resistance and impaired glucose metabolism. PMID- 29180326 TI - [Total knee arthroplasty with 3D printing technique versus conventional surgery: comparison of the outcomes]. AB - OBJECTIVE: To compare the clinical outcomes of patients receiving total knee arthroplasty (TKA) using 3D printing technique and conventional surgical methods. METHODS: From October, 2015 to February, 2017, 17 patients (20 knees) underwent TKA with the assistance of individualized navigation template and 16 concurrent patients (18 knees) matched for age, gender and knee society score received conventional TKA. The operation time, blood loss, and osteotomy data of the femoral condyle and tibia plateau were recorded. The mean femorotibial angle (MFTA) and sagittal tibial component angle (STCA) after the operation and the KSS at the last follow-up were compared between the two groups. RESULTS: All the patients were followed up for 7-23 months, during which no infection or prosthesis loosening or motion was found. In patients receiving surgery with 3D printing technique, the osteotomy data of the femoral condyle and tibia plateau in the actual surgeries were consistent with those in surgical plans (P>0.05). The patients in the 3D group had a significantly shorter operation time and a higher KSS score than those in the conventional group (P<0.05). Significant differences were found between the two groups in postoperative MFTA and STCA (P<0.05). CONCLUSION: The application of 3D printing technique can simplify the surgical procedure and improve the surgical precision and efficacy of TKA. PMID- 29180327 TI - [A probability model for analyzing speckles in intravascular ultrasound images to facilitate image segmentation]. AB - OBJECTIVE: Ultrasonic image speckles result from the interference of the reflected signals by the scatters in the detected tissue. The physical characteristics of the speckles are closely correlated with the structures of the biological tissues, and the probability distribution of these speckles differs across different tissues. Based on the probability characteristics of intravascular ultrasound (IVUS) speckles, a Gamma mixture model and Gaussian mixture model are proposed to describe the calcified plaque, soft plaque and normal vascular regions on IVUS images. Using KS test, KL divergence and correlation coefficient analysis, we found that the probability distributions of the speckles generated by calcified plaques and normal blood vessels were better described by the Gaussian mixture model, while the speckles caused by soft plaques were described better by the Gamma mixture model. Based on this finding, we propose a probability mixture model combining neighborhood information for plaque segmentation on IVUS images. Compared with the existing probabilistic mixture model, the segmentation accuracy was greatly improved with a reduced noise.

AB - OBJECTIVE: To investigate the role of alpha-enolase (ENO1) in regulating glucose metabolism and cell growth in human glioma cells. METHODS: Glucose uptake and lactate generation were assessed to evaluate the changes in glucose metabolism in human glioma U251 cells with small interfering RNA (siRNA)-mediated ENO1 knockdown. MTT assay and 5-ethynyl-2'-deoxyuridine (EdU) staining were used to examine the cell growth and cell cycle changes following siRNA transfection of the cells. RESULTS: Transfection of U251 cells with siRNA-ENO1 markedly reduced glucose uptake (P=0.023) and lactate generation (P=0.007) in the cells and resulted in significant suppression of cell proliferation (*P<0.05) since the second day following the transfection. Transfection with siRNA-ENO1 also obviously suppressed cell cycle G1/S transition in the cells (P=0.0425). The expressions of HK2 and LDHA, the marker genes for glucose metabolism, were significantly down-regulated in the cells with siRNA-mediated ENO1 knockdown. CONCLUSION: ENO1 as a potential oncogene promotes glioma cell growth by positively modulating glucose metabolism.

The cell proliferation and AKP activity were evaluated using CCK-8 assay kit and AKP assay kit, respectively. The effects of aldosterone on mRNA and protein expressions of the osteogenic genes and epithelial sodium channel (ENaC) gene were investigated using semi-quantitative PCR and Western blotting. RESULTS: Compared with the control cells, the cells treated with 0.01-1.0 umol/L aldosterone showed obviously enhanced proliferation while lower (1*10-3 umol/L) or higher (10 umol/L) concentrations of aldosterone did not significantly affect the cell proliferation. Aldosterone within the concentration range of 1*10-3 to 10 umol/L did not cause significant changes in AKP activity in the osteoblasts. Treatment with 0.01 to 1.0 umol/L aldosterone significantly upregulated the expressions of the osteogenic genes and alpha-ENaC gene at both the mRNA and protein levels. CONCLUSION: Aldosterone within the concentration range of 0.01-1.0 umol/L stimulates the proliferation and osteogenic gene expressions and enhances alpha-ENaC gene expression in rat osteoblasts in vitro, suggesting the possibility that ENaC participates in aldosterone-mediated regulation of osteoblast functions.

AB - OBJECTIVE: To explore the molecular mechanism underlying the biological function of lncRNA PTENP1 in bladder cancer. METHODS: Expressions of PTENP1, PTEN and miR 17 were examined by quantitative reverse transcriptase PCR (qRT-PCR) in 12 bladder cancer tissues. The expression of PTEN was examined by Western blotting in bladder cancer cell lines T24 and 5637 overexpressing PTENP1. Luciferase reporter assay was performed to confirm the targeting of miR-17 to PTENP1 and PTEN. T24 and 5637 cell lines with stable overexpression of PTENP1 and mir-17 were used to investigate effect of PTNE and miR-17 on the function of PTENP1 in bladder cancer. RESULTS: The expression of miR-17 was up-regulated and PTENP1 and PTEN were down-regulated in bladder cancer tissues, where a positive correlation was found between PTENP1 and PTEN expressions and a negative correlation between PTENP1 and miR-17 (P<0.05). Overexpression of PTENP1 in bladder cancer cell lines T24 and 5637 obviously enhanced the expression of PTEN protein. miR-17 was found to target both PTENP1 and PTEN and promote the growth of bladder cancer. miR-17 could partially restore the tumor-suppressing activity of PTENP1 in bladder cancer. CONCLUSION: By binding with miR-17, lncRNA PTENP1 functions as a PTEN competing endogenous RNA (ceRNA) to suppress the progression of bladder cancer.

AB - OBJECTIVE: To compare the clinical outcomes of in vitro fertilization and embryo transfer (IVF-ET) among patients in different conditions receiving luteinizing hormone supplementation in GnRH-agonist long protocol. METHODS: Between June, 2010 and December, 2015, 671 IVF-ET cycles with GnRH-agonist long protocol were performed at our center. These cycles were divided into group A with FSH only and group B with FSH and recombinant luteinizing hormone (r-LH) supplementation, and each group was divided into 4 subgroups according to age (<35 or >=35) and the LH level on the initial day (<1.0 U/L or >=1.0 U/L). The effects of LH supplementation on the clinical pregnancy rate and implantation rate were compared among different subgroups. RESULTS: No statistical significances were found between groups A and B in age, body mass index (BMI), basal FSH, basal LH, basal E2, Gn dosage, Gn day, LH on HCG day, E2 on HCG day, P on HCG day, number of oocytes, fertilization rate, available embryo rate or good quality embryo rate per oocyte, but the endometrium thickness on HCG day differed significantly between the two groups. In women below 35 years of age with a LH level on HCG day over 1.0 U/L, r-LH supplementation resulted in a clinical pregnancy rate of 60%, significantly lower than the rate of 79.55% in women without r-LH supplementation (P<0.05). In women over 35 years with a LH level below 1.0 U/L, r-LH supplementation resulted in an implantation rate of 44.74%, as compared with 24.74% in women without r-LH supplementation (P<0.05). CONCLUSION: In the long protocol, LH supplementation does not improve the oocyte number, fertilization rate, or good quality embryo per oocyte, and does not bring benefits to women below 35 years with a low LH level (<1.0 U/L) or those over 35 years with normal LH level (>=1.0 U/L) after GnRH-agonist administration. But for women over 35 years with low LH levels, r-LH supplementation may improve the clinical pregnancy rate and implantation rate of IVF-ET cycles. PMID- 29180332 TI - [Effect of dexmedetomidine postconditioning on myocardial ischemia-reperfusion injury and inflammatory response in diabetic rats]. AB - OBJECTIVE: To investigate the effect of dexmedetomidine postconditioning in alleviating myocardial ischemia-reperfusion (IR) injury and inflammation in diabetic mellitus rats. METHODS: Thirty normal male Sprauge Dawley (SD) rats were randomly allocated into 3 groups (n=10), namely the sham-operated group, IR group, and dexmedetomidine postconditioning (DP) group. Similarly, another thirty diabetic SD rats were also randomly allocated into diabetic sham (DM-S) group, diabetic IR (DM-IR) group and diabetic dexmedetomidine postconditioning (DM-DP) group. The mean arterial pressure (MAP), heart rate (HR) and the rate pressure product (RPP) were recorded at baseline, after 30 min of ischemia, and at 30 and 120 min during reperfusion. Myocardial infarct size was analyzed by TTC double staining method, and plasma levels of CTnI, TNF-a, IL-6, IL-10 and IL-1beta were measured at 120 min of reperfusion. RESULTS: Compared with those in the sham operated group, normal and diabetic rats in IR and DP groups showed significantly lowered MAP, HR, and RPP and increased levels of plasma CTnI, TNF-a, IL-6, IL-10 and IL-1beta levels after 30 min of ischemia and at 30 min and 120 min of reperfusion (P<0.05). Compared with those in the IR group, the normal rats in DP group showed decreased MAP, HR, and RPP at 30 min of ischemia and at 30 min of reperfusion, which increased at 120 min of reperfusion (P<0.05); the infarct size and plasma CTnI, TNF-a, IL-6 and IL-1beta levels were decreased while IL-10 was increased in DP group (P<0.05). Compared with those in DP group, the rats in DM DP group showed similar MAP, HR and RPP (P>0.05) but significantly increased infarct size and plasma CTnI, TNF-a, IL-6 and IL-1beta levels (P<0.05). CONCLUSION: Dexmedetomidine postconditioning may produce a cardioprotective effect against myocardial IR injury in normal rats by alleviating inflammation, but can not reduce the release of inflammatory mediators in diabetic rats to improve myocardial infarction. PMID- 29180333 TI - [Expressions of survivin, PI3K and AKT in keratinocytes in skin lesions and their pathogenic role in psoriasis vulgaris]. AB - OBJECTIVE: To explore the role of survivin and PI3K/AKT pathway in the pathogenesis of psoriasis vulgaris (PV). METHODS: Plaque-like lesions collected from 22 patients with PV in progressive stage and 18 normal control skin specimens were examined using immunohistochemical staining, Western blotting and real-time quantitative PCR for expressions of survivin, PI3K and AKT in the keratinocytes, and their correlation was analyzed. A small interfering RNA (siRNA) was used to knock down AKT in cultured HaCaT cells, and Western blotting was used to detect the changes in the expression of survivin. RESULTS Compared with normal skin, PV lesions showed obviously up-regulated expressions of survivin, PI3K and AKT in the keratinocytes. Survivin expression was positively correlated with PI3K (r=0.4510, P=0.0351) and AKT (r=0.4423, P=0.0393) in the keratinocytes in PV lesions. In cultured HaCaT cells, siRNA-mediated knockdown of AKT caused down-regulation of survivin expression. CONCLUSION: Survivin and PI3K/AKT signaling pathway may participate in the occurrence and progression of PV.

AB - OBJECTIVE: To identify specific protein markers for renal cell carcinoma detection and diagnosis, as well as develop new potential therapeutic targets of the disease. METHODS: We used two-dimensional difference in-gel electrophoresis (2-D DIGE) technique conjunction with mass spectrometry (MS) for the identification of significant differentially expressed proteins between 15cases of paired clear cell renal cell carcinoma (ccRCC) and adjacent normal renal tissues. The protein spots were considered as differentially expressed if a 1.5 fold altered expression level was observed (Student's t test, P value<0.05). RESULTS: Of the 27 differentially expressed protein spots, 26 proteins were successfully identified. 11 proteins up-regulated in renal cell carcinoma,15 proteins down-regulated. Among them Short/branched chain specific acyl-CoA dehydrogenase, mitochondrial (ACDSB), Aldose 1-epimerase (GALM), Peroxiredoxin-4 (PRDX4), Macrophage-capping protein (CAPG), Beta-defensin 107 (D107A), Microfibril-associated glycoprotein 4 (MFAP4) were first time screening as new differential expressed proteins by protomic study in renal cell carcinoma. CONCLUSIONS: 2-D DIGE is a useful technique for screening and analysis differential expressed proteins in renal cell carcinoma. These new differently expressed proteins may be useful for development new molecular markers for the tumor. PMID- 29180335 TI - [Pathogenic role of leukotriene B4 in pulmonary microvascular endothelial cell hyper- permeability induced by one lung ventilation in rabbits]. AB - OBJECTIVE: To elucidate the pathogenic role of leukotriene B4 (LTB4) in increased pulmonary microvascular endothelial cell permeability induced by one lung ventilation (OLV) in rabbits. METHODS: Forty-eight healthy Japanese white rabbits were randomly divided into control group (group C), saline pretreatment group (group S), bestatin (a leukotriene A4 hydrolase (LTA4H) inhibitor) plus saline pretreatment group (group B), OLV group (group O), saline pretreatment plus OLV group (group SO) and bestatin plus saline pretreatment with OLV group (group BO). ELISA was used to detect LTB4 content in the lung tissues, and LTA4H and phospholipase Cepsilonl (PLCEl) expressions were examined by Western blotting and quantitative PCR. The wet/dry weight (W/D) ratio of the lung, lung permeability index and the expressions of myosin light chain kinase (MLCK) protein and mRNA in the lung tissues were determined to evaluate the permeability of the pulmonary microvascular endothelial cells (PMVECs). The severities of lung injury were evaluated by lung histomorphological scores. RESULTS: No significant differences were found among groups C, S and B except that LTA4H expressions was significantly lower in group B than in groups C and S (P<0.05). OLV significantly increased the expressions of LTA4H (P<0.05) and resulted in LTB4 overproduction in the lungs (P<0.05) accompanied by significantly enhanced PLCE1 expression and PMVEC permeability (P<0.05). Pretreatment with bestatin, significantly reduced the expression of LTA4H and LTB4 production (P<0.05) and down-regulated the expression of PLCE1 in the lungs of the rabbits receiving OLV (P<0.05). CONCLUSION: Bestatin plays a protective role in OLV-induced rabbit lung injury by downregulating LTA4H to reduce the production of LTB4 in the lungs. LTB4 can increase PMVEC permeability by up-regulating PLCE1 expression in rabbits with OLV induced lung injury. PMID- 29180336 TI - [Protective effects of rutin against obesity-induced reproductive impairment in male mice]. AB - OBJECTIVE: To study the effect of rutin on body weight and obesity-induced reproductive impairment in male mice. METHODS: Twenty-four male mice were randomized equally into normal control group, high-fat diet group (HFD group), and HFD + rutin intervention group (HRU group). After 28 days of treatments, the testes and epididymis of the mice were collected for detection of total cholesterol (TC) and triglycerides (TG) levels and for pathological examinations with HE staining. The expressions of related genes was detected with real-time PCR, and Western blotting was used to detect the expression of Ucp1 protein in the samples. RESULTS: After 28 days of treatments, the mean body weight was lower in mice with rutin intervention than in those in HFD group. The mice in HFD group showed significantly higher TG levels in the testis and epididymis and higher TC levels in the epididymis than those in the control and HRU groups. In HFD group, the testis and the epididymis displayed loosened structures with abnormalcell structure, and the number ofmature spermatozoa in the lumen was decreased and the mobility of the sperms was reduced; all these changes were significantly alleviated in HRU group. The expression levels of Ucp1 mRNA and protein increased (P<0.05) and the expressions of Mcp1 and TNF-alpha decreased significantly in the mice after rutin treatment (P<0.05). CONCLUSION: Rutin can effectively inhibit rapid increase of body weight and protect against obesity-induced reproductive impairment in obese mice. PMID- 29180337 TI - [Effect of basic fibroblast growth factor antibody combined with irinotecan on proliferation and apoptosis of small cell lung cancer H223 cells in vitro]. AB - OBJECTIVE: To study the synergistic inhibitory effects of basic fibroblast growth factor (bFGF) monoclonal antibody (bFGF mAb) and irinotecan on the proliferation of small cell lung cancer H223 cells. METHODS: CCK-8 assay and flow cytometry were used to assess the effects of bFGF mAb combined with irinotecan on the proliferation and apoptosis of H223 cells, respectively. Western blotting was performed to analyze the effect of bFGF-mAb combined with irinotecan on AKT and ERK1/2 phosphorylation in the cells. RESULTS: Both bFGF mAb and irinotecan alone inhibited H223 cell proliferation in a dose-dependent manner (P<0.05). The inhibitory rate was significantly higher in H223 cells treated with bFGF mAb + irinotecan (54.30%) than in cell treated with bFGF mAb (18.73%) or irinotecan (21.96%) alone (P<0.05). Both bFGF mAb and irinotecan induced H223 cell apoptosis in a dose-dependent manner (P<0.05), and the combined treatment resulted in a significantly higher early apoptosis rates (6.5%) than treatment with bFGF mAb (2.7%) or irinotecan (4.3%) alone (P<0.05). bFGF mAb and irinotecan, either alone or in combination, significantly inhibited the levels of p-AKT protein and p ERK1/2 protein without obviously affecting AKT and ERK1/2 protein levels. CONCLUSION: bFGF mAb and irinotecan produce synergistic inhibitory effects on small cell lung cancer H223 cells by suppressing proliferation and promoting apoptosis of the cells, and can effectively block the MAPK/ERK and PI3K/AKT signaling pathways associated with bFGF. PMID- 29180338 TI - [Association of waist-to-hip ratio with insulin resistance in non-diabetic normal weight individuals: a cross-sectional study]. AB - OBJECTIVE: To explore the relationship between waist-to-hip ratio (WHR) and insulin resistance(IR) in non-diabetic normal-weight individuals and investigate how this association differs between male and femalesubjects. METHODS: From June to October, 2012, we performed a cross-sectional survey among 2142 community based non-diabetic Chinese participants, who were divided into 4 groups according to the gender-specific quartiles of WHR. Homeostatic model assessment of insulin resistance (HOMA-IR), calculated as the product of fasting plasma glucose (mmol/L) and fasting insulin (mU/L) divided by 22.5, was used as the indicator of insulin resistance. Logistic regression models were used to explore the association of WHR with IR in these subjects. RESULTS: In the unadjusted model, WHR was significantly associated with IR in women (OR=6.60, 95%CI: 2.86-15.26, P<0.001); the association was still significant (OR=3.28, 95%CI: 1.34-8.04, P=0.009) after adjustment for the potential confounders including the history of hypertension, coronary heartdisease, current smoker, physical inactivity, and body mass index. CONCLUSION: WHR is independently associated with IR in non diabetic Chinese women with normal body weight. PMID- 29180339 TI - [Deguelin inhibits proliferation and regulates the expression of MCM3-CDC45 in MCF-7 and H1299 cells in vitro]. AB - OBJECTIVE: To observe the effects of deguelin on the proliferation of breast cancer MCF-7 cells and lung cancer H1299 cells in vitro and the expression of minichromosome maintenance protein 3 (MCM3) and CDC45 in the cells. METHODS: MTT assay was used to evaluate the proliferation of MCF-7 and H1299 cells exposed to different concentrations of deguelin for 48, 72 or 96 h. The growth of the cells was observed microscopically and the changes of MCM3 and CDC45 expressions in MCF 7 and H1299 cells following deguelin treatment were detected with fluorescence quantitative PCR. RESULTS: The proliferation of MCF-7 cells was significantly inhibited by exposure to 0.25, 0.5, 1, 5, 10, 30, and 50 umol/L deguelin for 48, 72, and 96 h in a concentration- and time-dependent manner. In MCF-7 cells, the IC50 of deguelin at 48, 72, and 96 h was 9, 3, and 2 umol/L, respectively. Deguelin treatments of H1299 cells at 0.5, 1, 5, 10, 30, 50, and 100 umol/L also resulted in a concentration- and time-dependent inhibition of the cell growth with an IC50 at 96 h of 2 umol/L. Optical microscopy of the cells revealed a decreased number of viable cells with obvious cell shrinkage following deguelin treatments. The expression of MCM3 and CDC45 were significantly reduced in the cells after deguelin treatments. CONCLUSION: Deguelin can inhibit the proliferation of MCF-7 and H1299 cells in vitro and down-regulate the expression of MCM3 and CDC45 in the cells. PMID- 29180340 TI - [Association between hepatocyte growth factor in tears and corneal haze in rabbits early after epipolis laser in situ keratomileusis]. AB - OBJECTIVE: To study the dynamic changes of levels of hepatocyte growth factor (HGF) in tears and their association with corneal haze in rabbits early after epipolis laser in situ keratomileusis (Epi-LASIK). METHODS: Twenty-four New Zealand rabbits received Epi-LASIK with an ablation depth of 100 um in one eye and of 150 um in the other eye. Before and at 3, 7, 14, and 30 days after the surgery, the level of HGF in tears collected from the rabbits was measured using enzyme-linked immunosorbent assay (ELISA), and corneal haze was graded after surgery. RESULTS: In all the rabbits, corneal epithelium healing occurred in 3 to 5 days after Epi-LASIK. Corneal haze appeared 3 days postoperatively in the rabbits accompanied by increased levels of HGF in tears. At 3, 7, 14, and 30 days after the surgery, the rabbits with an ablation depth of 150 um showed more obvious corneal haze (P<0.05) and significantly higher levels of HGF in tears than those with an ablation depth of 100 um (P<0.05). CONCLUSION: In rabbits receiving Epi-LASIK, HGF levels in tears and the grade of corneal haze show a positive correlation early after the surgery and are both related with the depth of ablation.

AB - OBJECTIVE: To explore the diagnosis and treatment of pregnancy-associated acute Stanford type A aortic dissection to improve the maternal and fetal outcomes. METHODS: We analyzed the perioperative data of 5 pregnant women with acute Stanford type A aortic dissection treated between June, 2009 and February, 2017. RESULTS: The median age of the women was 30 years (range, 22-34 years) with gestational weeks of 23-38 weeks upon diagnosis. All the 5 patients received surgical interventions. Three patients underwent caesarean delivery and hysterectomy, and the fetuses survived after the surgery; 2 patients chose to continue pregnancy following the surgery, among whom one died due to postoperative complications and the other underwent termination of pregnancy. During follow-up, the surviving patients showed no endoleak in the descending aorta stent and the distal dissection remained stable. CONCLUSION: The maternal and fetal outcomes of pregnancy-associated acute Stanford type A aortic dissection can be improved by multidisciplinary cooperation and optimization of the surgical approaches according to the time of pregnancy, fetal development and conditions of the aortic lesions.

PMID- 29180344 TI - Behavioral Interventions to Prevent or Delay Dementia: Protocol for a Randomized Comparative Effectiveness Study. AB - BACKGROUND: Currently, people at risk for dementia and their caregivers are confronted with confusing choices about what behavioral interventions are most effective. OBJECTIVE: The objective of this study is to determine which empirically supported behavioral interventions most impact the outcomes highly valued by patients with mild cognitive impairment and their partners. METHODS: This protocol describes a comparative effectiveness trial targeting 300 participants with mild cognitive impairment and their study partners. The trial is being conducted at the Mayo Clinic campuses in Arizona, Florida, Minnesota, and the University of Washington in Seattle. The study examines the contribution of five behavioral interventions (yoga, memory compensation training, computerized cognitive training, support groups, and wellness education) on primary outcomes of participant and partner quality of life and self-efficacy. In this unique 10-day multicomponent intervention, groups of couples were randomized to have one of the five interventions withheld while receiving the other four. Although the longitudinal follow-up is still under way, enrollment results are available and reported. RESULTS: In total, 272 couples have been enrolled in the trial and follow-up visits continue. Outcomes will be assessed at the end-of intervention and 6-, 12-, and 18-month follow-ups. We anticipate reporting on our primary and secondary outcomes across time points in the next 2 years. CONCLUSIONS: This paper describes the protocol for a randomized comparative effectiveness study of behavioral interventions to prevent or delay dementia. We describe of the rationale, design, power analysis, and analysis plan. Also because enrollment is complete and we are in follow-up phases of the study, we have included enrollment data from the trial.

PMID- 29180345 TI - In-Person Versus eHealth Mindfulness-Based Intervention for Adolescents With Chronic Illness: Protocol for a Randomized Controlled Trial. AB - BACKGROUND: Eight-week mindfulness-based interventions (MBIs) have a beneficial impact on mental health and well-being in adolescents with chronic health conditions. Usually delivered in person in a group setting, these programs are difficult to access for teens with disabilities or who do not have in-person MBIs available in their communities. OBJECTIVE: This paper outlines the rationale, development, and design of a randomized controlled trial comparing the effects of an MBI delivered in person or via eHealth in adolescents with a chronic illness. Quantitative outcomes will include mindfulness skills acquisition (primary outcome), effects of the MBI on self-reported mood, anxiety, self-esteem, illness perception, and physiological stress (via salivary cortisol), and qualitative outcomes will include individual practice, participant appreciation, and adaptation of the MBI for eHealth. METHODS: This is a randomized noninferiority mixed methods study comparing 2 MBI arms: in-person and eHealth. Participants are eligible to participate if they are aged 13 to 18 years, have a diagnosis of chronic medical condition, live close enough to the recruitment hospital to participate in the in-person arm of the study, and are currently followed by a health care provider. Each participant will receive an adapted 8-week MBI delivered either in person at a tertiary pediatric hospital or via a secure audio visual platform allowing group interactions in real time. Groups will be facilitated by 2 experienced mindfulness providers. Quantitative and qualitative data will be collected through standardized research questionnaires administered via a secure, youth-friendly online platform and through semistructured interviews, participant log books, facilitator log books, and salivary cortisol analysis. Qualitative data will be analyzed using a grounded theory model. RESULTS: Data collection is currently underway. Data analysis, manuscript writing, and additional publications are expected to be completed in the winter and spring of 2018. CONCLUSIONS: Based on previous results from in-person trials conducted in adolescents and eHealth trials conducted in adults, we anticipate that both modes of delivery will significantly improve mindfulness skills acquisition, mood, anxiety, self-esteem, illness perception, and stress and that the magnitude of the effects will be correlated to the level of home practice. We predict that participants in both arms will show similar levels of home practice and that both modes of delivery will have high levels of feasibility and acceptability. If successful, this study could provide evidence for the use of eHealth in the delivery of 8-week MBIs in clinical adolescent populations, potentially increasing availability to MBIs for a large group of youth with mobility issues or living away from large urban centers.

PMID- 29180346 TI - Relationship Between the Menstrual Cycle and Timing of Ovulation Revealed by New Protocols: Analysis of Data from a Self-Tracking Health App. AB - BACKGROUND: There are many mobile phone apps aimed at helping women map their ovulation and menstrual cycles and facilitating successful conception (or avoiding pregnancy). These apps usually ask users to input various biological features and have accumulated the menstrual cycle data of a vast number of women. OBJECTIVE: The purpose of our study was to clarify how the data obtained from a self-tracking health app for female mobile phone users can be used to improve the accuracy of prediction of the date of next ovulation. METHODS: Using the data of 7043 women who had reliable menstrual and ovulation records out of 8,000,000 users of a mobile phone app of a health care service, we analyzed the relationship between the menstrual cycle length, follicular phase length, and luteal phase length. Then we fitted a linear function to the relationship between the length of the menstrual cycle and timing of ovulation and compared it with the existing calendar-based methods. RESULTS: The correlation between the length of the menstrual cycle and the length of the follicular phase was stronger than the correlation between the length of the menstrual cycle and the length of the luteal phase, and there was a positive correlation between the lengths of past and future menstrual cycles. A strong positive correlation was also found between the mean length of past cycles and the length of the follicular phase. The correlation between the mean cycle length and the luteal phase length was also statistically significant. In most of the subjects, our method (ie, the calendar based method based on the optimized function) outperformed the Ogino method of predicting the next ovulation date. Our method also outperformed the ovulation date prediction method that assumes the middle day of a mean menstrual cycle as the date of the next ovulation. CONCLUSIONS: The large number of subjects allowed us to capture the relationships between the lengths of the menstrual cycle, follicular phase, and luteal phase in more detail than previous studies. We then demonstrated how the present calendar methods could be improved by the better grouping of women. This study suggested that even without integrating various biological metrics, the dataset collected by a self-tracking app can be used to develop formulas that predict the ovulation day when the data are aggregated. Because the method that we developed requires data only on the first day of menstruation, it would be the best option for couples during the early stages of their attempt to have a baby or for those who want to avoid the cost associated with other methods. Moreover, the result will be the baseline for more advanced methods that integrate other biological metrics. PMID- 29180347 TI - Effectiveness and safety of acupuncture combined with Madopar for Parkinson's disease: a systematic review with meta-analysis. AB - OBJECTIVE: To evaluate the effectiveness and safety of acupuncture combined with Madopar for the treatment of Parkinson's disease (PD), compared to the use of Madopar alone. METHODS: A systematic search was carried out for randomised controlled trials (RCTs) of acupuncture and Madopar for the treatment of PD published between April 1995 and April 2015. The primary outcome was total effectiveness rate and secondary outcomes included Unified Parkinson's Disease Rating Scale (UPDRS) scores. Data were pooled and analysed with RevMan 5.3. Results were expressed as relative ratio (RR) with 95% confidence interval (CIs). RESULTS: Finally, 11 RCTs with 831 subjects were included. Meta-analyses showed that acupuncture combined with Madopar for the treatment of PD can significantly improve the clinical effectiveness compared with Madopar alone (RR=1.28, 95% CI 1.18 to 1.38, P<0.001). It was also found that acupuncture combined with Madopar significantly improved the UPDRS II (SMD=-1.00, 95% CI -1.71 to -0.29, P=0.006) and UPDRS I-IV total summed scores (SMD=-1.15, 95% CI -1.63 to -0.67, P<0.001) but not UPDRS I (SMD=-0.37, 95% CI -0.77 to 0.02, P=0.06), UPDRS III (SMD=-0.93, 95% CI -2.28 to 0.41, P=0.17) or UPDRS IV (SMD=-0.78, 95% CI -2.24 to 0.68, P=0.30) scores. Accordingly, acupuncture combined with Madopar appeared to have a positive effect on activities of daily life and the general condition of patients with PD, but was not better than Madopar alone for the treatment of mental activity, behaviour, mood and motor disability. In the safety evaluation, it was found that acupuncture combined with Madopar was associated with significantly fewer adverse effects including gastrointestinal reactions (RR=0.38, 95% CI 0.23 to 0.65, P<0.001), on-off phenomena (RR=0.27, 95% CI 0.11 to 0.66, P=0.004) and mental disorders (RR=0.24, 95% CI 0.06 to 0.92, P=0.04) but did not significantly reduce dyskinesia (RR=0.64, 95% CI 0.35 to 1.16, P=0.14). CONCLUSION: Acupuncture combined with Madopar appears, to some extent, to improve clinical effectiveness and safety in the treatment of PD, compared with Madopar alone. This conclusion must be considered cautiously, given the quality of most of the studies included was low. Therefore, more high-quality, multicentre, prospective, RCTs with large sample sizes are needed to further clarify the effect of acupuncture combined with Madopar for PD. PMID- 29180350 TI - Undergraduate Performance in Solving Ill-Defined Biochemistry Problems. AB - With growing interest in promoting skills related to the scientific process, we studied performance in solving ill-defined problems demonstrated by graduating biochemistry majors at a public, minority-serving university. As adoption of techniques for facilitating the attainment of higher-order learning objectives broadens, so too does the need to appropriately measure and understand student performance. We extended previous validation of the Individual Problem Solving Assessment (IPSA) and administered multiple versions of the IPSA across two semesters of biochemistry courses. A final version was taken by majors just before program exit, and student responses on that version were analyzed both quantitatively and qualitatively. This mixed-methods study quantifies student performance in scientific problem solving, while probing the qualitative nature of unsatisfactory solutions. Of the five domains measured by the IPSA, we found that average graduates were only successful in two areas: evaluating given experimental data to state results and reflecting on performance after the solution to the problem was provided. The primary difficulties in each domain were quite different. The most widespread challenge for students was to design an investigation that rationally aligned with a given hypothesis. We also extend the findings into pedagogical recommendations. PMID- 29180348 TI - Phenotype-genotype spectrum of AAA syndrome from Western India and systematic review of literature. AB - OBJECTIVE: To study genotype-phenotype spectrum of triple A syndrome (TAS). METHODS: Retrospective chart analysis of Indian TAS patients (cohort 1, n = 8) and review of genotyped TAS cases reported in world literature (cohort 2, n = 133, 68 publications). RESULTS: Median age at presentation was 4.75 years (range: 4-10) and 5 years (range: 1-42) for cohorts 1 and 2, respectively. Alacrima, adrenal insufficiency (AI), achalasia and neurological dysfunction (ND) were seen in 8/8, 8/8, 7/8 and 4/8 patients in cohort 1, and in 99, 91, 93 and 79% patients in cohort 2, respectively. In both cohorts, alacrima was present since birth while AI and achalasia manifested before ND. Mineralocorticoid deficiency (MC) was uncommon (absent in cohort 1, 12.5% in cohort 2). In cohort 1, splice-site mutation in exon 1 (p.G14Vfs*45) was commonest, followed by a deletion in exon 8 (p.S255Vfs*36). Out of 65 mutations in cohort 2, 14 were recurrent and five exhibited regional clustering. AI was more prevalent, more often a presenting feature, and was diagnosed at younger age in T group (those with truncating mutations) as compared to NT (non-truncating mutations) group. ND was more prevalent, more common a presenting feature, with later age at onset in NT as compared to T group. CONCLUSION: Clinical profile of our patients is similar to that of patients worldwide. Alacrima is the earliest and most consistent finding. MC deficiency is uncommon. Some recurrent mutations show regional clustering. p.G14Vfs*45 and p.S255Vfs*36 account for majority of AAAS mutations in our cohort. Phenotype of T group differs from that of NT group and merits future research. PMID- 29180351 TI - Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) Inhibitors and Incident Type 2 Diabetes: A Systematic Review and Meta-analysis With Over 96,000 Patient Years. AB - OBJECTIVE: Like mutations with loss of function in the proprotein convertase subtilisin/kexin type 9 (PCSK9) gene, inhibitors of PCSK9 (PCSK9i) may potentially favor the manifestation of diabetes. RESEARCH DESIGN AND METHODS: A meta-analysis of phase 2/3 randomized clinical trials (RCTs) assessed PCSK9i versus placebo in the primary hypercholesterolemia setting. Statins and ezetimibe were used in 98.4% of these studies and balanced between PCSK9i and placebo. We calculated relative risks (RRs) and 95% CIs using random- and fixed-effect models. RESULTS: We included 68,123 participants (20 RCTs) with median follow-up of 78 weeks. PCSK9i increased fasting blood glucose (weighted mean difference 1.88 mg/dL [95% CI 0.91-2.68]; I2 = 0%; P < 0.001) and HbA1c (0.032% [0.011 0.050]; I2 = 15.5%; P < 0.001) when compared with placebo. This effect was not sufficient to increase incidence of diabetes (RR 1.04 [0.96-1.13]; I2 = 0%; P = 0.427). Exploratory meta-regression analyses indicated an association between the increased risk of diabetes and the potency (P = 0.029) and duration (P = 0.026) of PCSK9i treatment. CONCLUSIONS: In the short term, PCSK9i therapy favors a small but significant increase in plasma glycemia and HbA1c.

PMID- 29180353 TI - Clec16a, Nrdp1, and USP8 Form a Ubiquitin-Dependent Tripartite Complex That Regulates beta-Cell Mitophagy. AB - Mitophagy is a cellular quality-control pathway, which is essential for elimination of unhealthy mitochondria. While mitophagy is critical to pancreatic beta-cell function, the posttranslational signals governing beta-cell mitochondrial turnover are unknown. Here, we report that ubiquitination is essential for the assembly of a mitophagy regulatory complex, comprised of the E3 ligase Nrdp1, the deubiquitinase enzyme USP8, and Clec16a, a mediator of beta cell mitophagy with unclear function. We discover that the diabetes gene Clec16a encodes an E3 ligase, which promotes nondegradative ubiquitin conjugates to direct its mitophagy effectors and stabilize the Clec16a-Nrdp1-USP8 complex. Inhibition of the Clec16a pathway by the chemotherapeutic lenalidomide, a selective ubiquitin ligase inhibitor associated with new-onset diabetes, impairs beta-cell mitophagy, oxygen consumption, and insulin secretion. Indeed, patients treated with lenalidomide develop compromised beta-cell function. Moreover, the beta-cell Clec16a-Nrdp1-USP8 mitophagy complex is destabilized and dysfunctional after lenalidomide treatment as well as after glucolipotoxic stress. Thus, the Clec16a-Nrdp1-USP8 complex relies on ubiquitin signals to promote mitophagy and maintain mitochondrial quality control necessary for optimal beta-cell function. PMID- 29180356 TI - Just When We Thought We Knew Everything We Needed To Know about Zn Acquisition and Bacterial Pathogenesis. AB - It is well established that high-affinity zinc importers play essential roles in bacterial virulence, but the studies described by Moreau et al. in this issue (G. B. Moreau, A. Qin, and B. J. Mann, J Bacteriol 200:e00587-17, 2018, https://doi.org/10.1128/JB.00587-17) demonstrate that we probably still have much to learn about how these transporters function and how the genes that encode them are regulated in different bacterial pathogens. PMID- 29180355 TI - Photoreceptor glucose metabolism determines normal retinal vascular growth. AB - The neural cells and factors determining normal vascular growth are not well defined even though vision-threatening neovessel growth, a major cause of blindness in retinopathy of prematurity (ROP) (and diabetic retinopathy), is driven by delayed normal vascular growth. We here examined whether hyperglycemia and low adiponectin (APN) levels delayed normal retinal vascularization, driven primarily by dysregulated photoreceptor metabolism. In premature infants, low APN levels correlated with hyperglycemia and delayed retinal vascular formation. Experimentally in a neonatal mouse model of postnatal hyperglycemia modeling early ROP, hyperglycemia caused photoreceptor dysfunction and delayed neurovascular maturation associated with changes in the APN pathway; recombinant mouse APN or APN receptor agonist AdipoRon treatment normalized vascular growth. APN deficiency decreased retinal mitochondrial metabolic enzyme levels particularly in photoreceptors, suppressed retinal vascular development, and decreased photoreceptor platelet-derived growth factor (Pdgfb). APN pathway activation reversed these effects. Blockade of mitochondrial respiration abolished AdipoRon-induced Pdgfb increase in photoreceptors. Photoreceptor knockdown of Pdgfb delayed retinal vascular formation. Stimulation of the APN pathway might prevent hyperglycemia-associated retinal abnormalities and suppress phase I ROP in premature infants. PMID- 29180358 TI - Nonclinical Cardiovascular Studies of Prucalopride, a Highly Selective 5 Hydroxytryptamine 4 Receptor Agonist. AB - Patients with chronic constipation benefit from treatment with 5 hydroxytryptamine 4 (5-HT4) receptor agonists. However, the first-generation 5 HT4 receptor agonists cisapride and tegaserod were withdrawn from the market owing to rare cardiovascular adverse events that were not 5-HT4-receptor-related but due to the lack of selectivity of these drugs. Here we report the nonclinical cardiovascular profile of the selective 5-HT4 receptor agonist prucalopride. To assess its non-5-HT4 receptor-mediated effects on cardiovascular electrophysiological parameters, in vitro studies were performed in human ether-a go-go-related gene-transfected cells, guinea pig ventricular myocytes and papillary muscle preparations, rabbit and dog Purkinje fibers, and the Langendorff rabbit heart. In vivo experiments were performed in a rabbit model for drug-induced proarrhythmogenesis, in anesthetized guinea pigs, and anesthetized and conscious dogs. In addition, human platelet aggregation and coronary artery contraction were studied to exclude interactions that have been suggested to mediate the cardiovascular effects of tegaserod. Effects at 5-HT4 receptors were evaluated in piglet and human atrial myocardium, and in anesthetized pigs. Finally, cardiovascular endpoints were investigated in chronic, repeated-dose toxicology studies at very high prucalopride doses in rats and dogs. No relevant effects were observed in any of the cardiovascular studies at concentrations at least 50 times the therapeutic plasma level. Only in pigs were minor and transient increases in heart rate and blood pressure noted upon first exposure to prucalopride, at plasma levels at least 10 times higher than human therapeutic plasma levels. Prucalopride may thus provide therapeutic benefit without the cardiovascular risks reported for other 5-HT4 receptor agonists. PMID- 29180357 TI - Pseudouridine-Free Escherichia coli Ribosomes. AB - Pseudouridine (Psi) is present at conserved, functionally important regions in the ribosomal RNAs (rRNAs) from all three domains of life. Little, however, is known about the functions of Psi modifications in bacterial ribosomes. An Escherichia coli strain has been constructed in which all seven rRNA Psi synthases have been inactivated and whose ribosomes are devoid of all Psis. Surprisingly, this strain displays only minor defects in ribosome biogenesis and function, and cell growth is only modestly affected. This is in contrast to a strong requirement for Psi in eukaryotic ribosomes and suggests divergent roles for rRNA Psi modifications in these two domains.IMPORTANCE Pseudouridine (Psi) is the most abundant posttranscriptional modification in RNAs. In the ribosome, Psi modifications are typically located at conserved, critical regions, suggesting they play an important functional role. In eukarya and archaea, rRNAs are modified by a single pseudouridine synthase (PUS) enzyme, targeted to rRNA via a snoRNA-dependent mechanism, while bacteria use multiple stand-alone PUS enzymes. Disruption of Psi modification of rRNA in eukarya seriously impairs ribosome function and cell growth. We have constructed an E. coli multiple deletion strain lacking all Psi modifications in rRNA. In contrast to the equivalent eukaryotic mutants, the E. coli strain is only modestly affected in growth, decoding, and ribosome biogenesis, indicating a differential requirement for Psi modifications in these two domains. PMID- 29180359 TI - Tegoprazan, a Novel Potassium-Competitive Acid Blocker to Control Gastric Acid Secretion and Motility. AB - Tegoprazan [(S)-4-((5,7-difluorochroman-4-yl)oxy)-N,N,2-trimethyl-1H benzo[d]imidazole-6-carboxamide], a potassium-competitive acid blocker (P-CAB), is a novel potent and highly selective inhibitor of gastric H+/K+-ATPase. Tegoprazan inhibited porcine, canine, and human H+/K+-ATPases in vitro with IC50 values ranging from 0.29 to 0.52 MUM, while that for canine kidney Na+/K+-ATPase was more than 100 MUM. A kinetic analysis revealed that tegoprazan inhibited H+/K+-ATPase in a potassium-competitive manner and the binding was reversible. Oral single administrations of tegoprazan ranging from 0.3 to 30 mg/kg in dogs were well absorbed into the blood stream and distributed in gastric tissue/fluid higher than in plasma. Tegoprazan potently inhibited histamine-induced gastric acid secretion in dogs, and a complete inhibition was observed at 1.0 mg/kg starting from 1 hour after administration. Moreover, an oral administration of tegoprazan at 1 and 3 mg/kg reversed the pentagastrin-induced acidified gastric pH to the neutral range. Interestingly, 3 mg/kg tegoprazan immediately evoked a gastric phase III contraction of the migrating motor complex in pentagastrin treated dogs and similar effects was observed with the other P-CAB, vonoprazan. Tegoprazan is the novel P-CAB that may provide a new option for the therapy of gastric acid-related and motility-impaired diseases. PMID- 29180360 TI - Production and Biotechnological Potential of Extracellular Polymeric Substances from Sponge-Associated Antarctic Bacteria. AB - Four sponge-associated Antarctic bacteria (i.e., Winogradskyella sp. strains CAL384 and CAL396, Colwellia sp. strain GW185, and Shewanella sp. strain CAL606) were selected for the highly mucous appearance of their colonies on agar plates. The production of extracellular polymeric substances (EPSs) was enhanced by a step-by-step approach, varying the carbon source, substrate and NaCl concentrations, temperature, and pH. The EPSs produced under optimal conditions were chemically characterized, resulting in a moderate carbohydrate content (range, 15 to 28%) and the presence of proteins (range, 3 to 24%) and uronic acids (range, 3.2 to 11.9%). Chemical hydrolysis of the carbohydrate portion revealed galactose, glucose, galactosamine, and mannose as the principal constituents. The potential biotechnological applications of the EPSs were also investigated. The high protein content in the EPSs from Winogradskyella sp. CAL384 was probably responsible for the excellent emulsifying activity toward tested hydrocarbons, with a stable emulsification index (E24) higher than those recorded for synthetic surfactants. All the EPSs tested in this work improved the freeze-thaw survival ratio of the isolates, suggesting that they may be exploited as cryoprotection agents. The addition of a sugar in the culture medium, by stimulating EPS production, also allowed isolates to grow in the presence of higher concentrations of mercury and cadmium. This finding was probably dependent on the presence of uronic acids and sulfate groups, which can act as ligands for cations, in the extracted EPSs.IMPORTANCE To date, biological matrices have never been employed for the investigation of EPS production by Antarctic psychrotolerant marine bacteria. The biotechnological potential of extracellular polymeric substances produced by Antarctic bacteria is very broad and comprises many advantages, due to their biodegradability, high selectivity, and specific action compared to synthetic molecules. Here, several interesting EPS properties have been highlighted, such as emulsifying activity, cryoprotection, biofilm formation, and heavy metal chelation, suggesting their potential applications in cosmetic, environmental, and food biotechnological fields as valid alternatives to the commercial polymers currently used. PMID- 29180361 TI - Production of 1-Dodecanol, 1-Tetradecanol, and 1,12-Dodecanediol through Whole Cell Biotransformation in Escherichia coli. AB - Medium- and long-chain 1-alkanol and alpha,omega-alkanediols are used in personal care products, in industrial lubricants, and as precursors for polymers synthesized for medical applications. The industrial production of alpha,omega alkanediols by alkane hydroxylation primarily occurs at high temperature and pressure using heavy metal catalysts. However, bioproduction has recently emerged as a more economical and environmentally friendly alternative. Among alkane monooxygenases, CYP153A from Marinobacter aquaeolei VT8 (CYP153A M.aq ; the strain is also known as Marinobacter hydrocarbonoclasticus VT8) possesses low overoxidation activity and high regioselectivity and thus has great potential for use in terminal hydroxylation. However, the application of CYP153A M.aq is limited because it is encoded by a dysfunctional operon. In this study, we demonstrated that the operon regulator AlkR M.aq is functional, can be induced by alkanes of various lengths, and does not suffer from product inhibition. Additionally, we identified a transposon insertion in the CYP153A M.aq operon. When the transposon was removed, the expression of the operon genes could be induced by alkanes, and the alkanes could then be oxyfunctionalized by the resulting proteins. To increase the accessibility of medium- and long-chain alkanes, we coexpressed a tunable alkane facilitator (AlkL) from Pseudomonas putida GPo1. Using a recombinant Escherichia coli strain, we produced 1.5 g/liter 1-dodecanol in 20 h and 2 g/liter 1-tetradecanol in 50 h by adding dodecane and tetradecane, respectively. Furthermore, in 68 h, we generated 3.76 g/liter of 1,12-dodecanediol by adding a dodecane-1-dodecanol substrate mixture. This study reports a very efficient method of producing C12/C14 alkanols and C12 1,12 alkanediol by whole-cell biotransformation.IMPORTANCE To produce terminally hydroxylated medium- to long-chain alkane compounds by whole-cell biotransformation, substrate permeability, enzymatic activity, and the control of overoxidability should be considered. Due to difficulties in production, small amounts of 1-dodecanol, 1-tetradecanol, and 1,12-dodecanediol are typically produced. In this study, we identified an alkane-inducible monooxygenase operon that can efficiently catalyze the conversion of alkane to 1-alkanol with no detection of the overoxidation product. By coexpressing an alkane membrane facilitator, high levels of 1-dodecanol, 1-tetradecanol, and 1,12-dodecanediol could be generated. This study is significant for the bioproduction of medium- and long-chain 1-alkanol and alpha,omega-alkanediols. PMID- 29180362 TI - Limited Effects of Variable-Retention Harvesting on Fungal Communities Decomposing Fine Roots in Coastal Temperate Rainforests. AB - Fine root litter is the principal source of carbon stored in forest soils and a dominant source of carbon for fungal decomposers. Differences in decomposer capacity between fungal species may be important determinants of fine-root decomposition rates. Variable-retention harvesting (VRH) provides refuge for ectomycorrhizal fungi, but its influence on fine-root decomposers is unknown, as are the effects of functional shifts in these fungal communities on carbon cycling. We compared fungal communities decomposing fine roots (in litter bags) under VRH, clear-cut, and uncut stands at two sites (6 and 13 years postharvest) and two decay stages (43 days and 1 year after burial) in Douglas fir forests in coastal British Columbia, Canada. Fungal species and guilds were identified from decomposed fine roots using high-throughput sequencing. Variable retention had short-term effects on beta-diversity; harvest treatment modified the fungal community composition at the 6-year-postharvest site, but not at the 13-year postharvest site. Ericoid and ectomycorrhizal guilds were not more abundant under VRH, but stand age significantly structured species composition. Guild composition varied by decay stage, with ruderal species later replaced by saprotrophs and ectomycorrhizae. Ectomycorrhizal abundance on decomposing fine roots may partially explain why fine roots typically decompose more slowly than surface litter. Our results indicate that stand age structures fine-root decomposers but that decay stage is more important in structuring the fungal community than shifts caused by harvesting. The rapid postharvest recovery of fungal communities decomposing fine roots suggests resiliency within this community, at least in these young regenerating stands in coastal British Columbia.IMPORTANCE Globally, fine roots are a dominant source of carbon in forest soils, yet the fungi that decompose this material and that drive the sequestration or respiration of this carbon remain largely uncharacterized. Fungi vary in their capacity to decompose plant litter, suggesting that fungal community composition is an important determinant of decomposition rates. Variable-retention harvesting is a forestry practice that modifies fungal communities by providing refuge for ectomycorrhizal fungi. We evaluated the effects of variable retention and clear-cut harvesting on fungal communities decomposing fine roots at two sites (6 and 13 years postharvest), at two decay stages (43 days and 1 year), and in uncut stands in temperate rainforests. Harvesting impacts on fungal community composition were detected only after 6 years after harvest. We suggest that fungal community composition may be an important factor that reduces fine-root decomposition rates relative to those of above-ground plant litter, which has important consequences for forest carbon cycling. PMID- 29180363 TI - Silver Nanoparticles Complexed with Bovine Submaxillary Mucin Possess Strong Antibacterial Activity and Protect against Seedling Infection. AB - A simple method for the synthesis of nanoparticles (NPs) of silver (Ag) in a matrix of bovine submaxillary mucin (BSM) was reported previously by some of the authors of this study. Based on mucin characteristics such as long-lasting stability, water solubility, and surfactant and adhesive characteristics, we hypothesized that these compounds, named BSM-Ag NPs, may possess favorable properties as potent antimicrobial agents. The goal of this study was to assess whether BSM-Ag NPs possess antibacterial activity, focusing on important plant pathogenic bacterial strains representing both Gram-negative (Acidovorax and Xanthomonas) and Gram-positive (Clavibacter) genera. Growth inhibition and bactericidal assays, as well as electron microscopic observations, demonstrate that BSM-Ag NPs, at relatively low concentrations of silver, exert strong antimicrobial effects. Moreover, we show that treatment of melon seeds with BSM Ag NPs effectively prevents seed-to-seedling transmission of Acidovorax citrulli, one of the most threatening pathogens of cucurbit production worldwide. Overall, our findings demonstrate strong antimicrobial activity of BSM-Ag NPs and their potential application for reducing the spread and establishment of devastating bacterial plant diseases in agriculture.IMPORTANCE Bacterial plant diseases challenge agricultural production, and the means available to manage them are limited. Importantly, many plant-pathogenic bacteria have the ability to colonize seeds, and seed-to-seedling transmission is a critical route by which bacterial plant diseases spread to new regions and countries. The significance of our study resides in the following aspects: (i) the simplicity of the method of BSM-Ag NP synthesis, (ii) the advantageous chemical properties of BSM-Ag NPs, (iii) the strong antibacterial activity of BSM-Ag NPs at relatively low concentrations of silver, and (iv) the fact that, in contrast to most studies on the effects of metal NPs on plant pathogens, the proof of concept for the novel compound is supported by in planta assays. Application of this technology is not limited to agriculture; BSM-Ag NPs potentially could be exploited as a potent antimicrobial agent in a wide range of industrial areas, including medicine, veterinary medicine, cosmetics, textiles, and household products. PMID- 29180364 TI - Genetic Plasticity and Ethylmalonyl Coenzyme A Pathway during Acetate Assimilation in Rhodospirillum rubrum S1H under Photoheterotrophic Conditions. AB - Purple nonsulfur bacteria represent a promising resource for biotechnology because of their great metabolic versatility. Rhodospirillum rubrum has been widely studied regarding its metabolism of volatile fatty acid, mainly acetate. As the glyoxylate shunt is unavailable in Rs. rubrum, the citramalate cycle pathway and the ethylmalonyl-coenzyme A (CoA) pathway are proposed as alternative anaplerotic pathways for acetate assimilation. However, despite years of debate, neither has been confirmed to be essential. Here, using functional genomics, we demonstrate that the ethylmalonyl-CoA pathway is required for acetate photoassimilation. Moreover, an unexpected reversible long-term adaptation is observed, leading to a drastic decrease in the lag phase characterizing the growth of Rs. rubrum in the presence of acetate. Using proteomic and genomic analyses, we present evidence that the adaptation phenomenon is associated with reversible amplification and overexpression of a 60-kb genome fragment containing key enzymes of the ethylmalonyl-CoA pathway. Our observations suggest that a genome duplication and amplification phenomenon is not only involved in adaptation to acute stress but can also be important for basic carbon metabolism and the redox balance.IMPORTANCE Purple nonsulfur bacteria represent a major group of anoxygenic photosynthetic bacteria that emerged as a promising resource for biotechnology because of their great metabolic versatility and ability to grow under various conditions. Rhodospirillum rubrum S1H has notably been selected by the European Space Agency to colonize its life support system, called MELiSSA, due to its capacity to perform photoheterotrophic assimilation of volatile fatty acids (VFAs), mainly acetate. VFAs are valuable carbon sources for many applications, combining bioremediation of contaminated environments with the generation of added-value products. Acetate is one of the major volatile fatty acids generated as a by-product of fermentation processes. In Rs. rubrum, purple nonsulfur bacteria, the assimilation of acetate is still under debate since two different pathways have been proposed. Here, we clearly demonstrate that the ethylmalonyl-CoA pathway is the major anaplerotic pathway for acetate assimilation in this strain. Interestingly, we further observed that gene duplication and amplification, which represent a well-known phenomenon in antibiotic resistance, also play a regulatory function in carbon metabolism and redox homeostasis. PMID- 29180365 TI - Nutrient co-limited Trichodesmium as nitrogen source or sink in a future ocean. AB - Nitrogen-fixing (N2) cyanobacteria provide bioavailable nitrogen to vast ocean regions but are in turn limited by iron (Fe) and/or phosphorus (P), which may force them to employ alternative nitrogen acquisition strategies. The adaptive responses of nitrogen-fixers to global-change drivers under nutrient-limited conditions could profoundly alter the current ocean nitrogen and carbon cycles. Here, we show that the globally-important N2-fixer Trichodesmium fundamentally shifts nitrogen metabolism towards organic-nitrogen scavenging following long term high-CO2 adaptation under iron and/or phosphorus (co)-limitation. Global shifts in transcripts and proteins under high CO2/Fe-limited and/or P-limited conditions include decreases in the N2-fixing nitrogenase enzyme, coupled with major increases in enzymes that oxidize trimethylamine (TMA). TMA is an abundant, biogeochemically-important organic nitrogen compound that supports rapid Trichodesmium growth while inhibiting N2 fixation. In a future high-CO2 ocean, this whole-cell energetic reallocation towards organic nitrogen scavenging and away from N2-fixation may reduce new-nitrogen inputs by Trichodesmium, while simultaneously depleting the scarce fixed-nitrogen supplies of nitrogen-limited open ocean ecosystems.ImportanceTrichodesmium is among the most biogeochemically significant microorganisms in the ocean, since it supplies up to 50% of the new nitrogen supporting open ocean food webs. We used Trichodesmium cultures adapted to high CO2 for 7 years followed by additional exposure to iron and/or phosphorus (co)-limitation. We show that 'future ocean' conditions of high CO2 and concurrent nutrient limitation(s) fundamentally shift nitrogen metabolism away from nitrogen fixation, and instead towards upregulation of organic-nitrogen scavenging pathways. We show that Trichodesmium's responses to projected future ocean conditions include decreases in the nitrogen-fixing nitrogenase enzymes, coupled with major increases in enzymes that oxidize the abundant organic nitrogen source trimethylamine (TMA). Such a shift towards organic nitrogen uptake and away from nitrogen fixation may substantially reduce new-nitrogen inputs by Trichodesmium to the rest of the microbial community in the future high CO2 ocean, with potential global implications for ocean carbon and nitrogen cycling. PMID- 29180366 TI - In Vitro Enzymatic Depolymerization of Lignin with Release of Syringyl, Guaiacyl, and Tricin Units. AB - New environmentally sound technologies are needed to derive valuable compounds from renewable resources. Lignin, an abundant polymer in terrestrial plants comprised predominantly of guaiacyl and syringyl monoaromatic phenylpropanoid units, is a potential natural source of aromatic compounds. In addition, the plant secondary metabolite tricin is a recently discovered and moderately abundant flavonoid in grasses. The most prevalent interunit linkage between guaiacyl, syringyl, and tricin units is the beta-ether linkage. Previous studies have shown that bacterial beta-etherase pathway enzymes catalyze glutathione dependent cleavage of beta-ether bonds in dimeric beta-ether lignin model compounds. To date, however, it remains unclear whether the known beta-etherase enzymes are active on lignin polymers. Here we report on enzymes that catalyze beta-ether cleavage from bona fide lignin, under conditions that recycle the cosubstrates NAD+ and glutathione. Guaiacyl, syringyl, and tricin derivatives were identified as reaction products when different model compounds or lignin fractions were used as substrates. These results demonstrate an in vitro enzymatic system that can recycle cosubstrates while releasing aromatic monomers from model compounds as well as natural and engineered lignin oligomers. These findings can improve the ability to produce valuable aromatic compounds from a renewable resource like lignin.IMPORTANCE Many bacteria are predicted to contain enzymes that could convert renewable carbon sources into substitutes for compounds that are derived from petroleum. The beta-etherase pathway present in sphingomonad bacteria could cleave the abundant beta-O-4-aryl ether bonds in plant lignin, releasing a biobased source of aromatic compounds for the chemical industry. However, the activity of these enzymes on the complex aromatic oligomers found in plant lignin is unknown. Here we demonstrate biodegradation of lignin polymers using a minimal set of beta-etherase pathway enzymes, the ability to recycle needed cofactors (glutathione and NAD+) in vitro, and the release of guaiacyl, syringyl, and tricin as depolymerized products from lignin. These observations provide critical evidence for the use and future optimization of these bacterial beta-etherase pathway enzymes for industrial-level biotechnological applications designed to derive high-value monomeric aromatic compounds from lignin. PMID- 29180367 TI - GH30 Glucuronoxylan-Specific Xylanase from Streptomyces turgidiscabies C56. AB - Endoxylanases are important enzymes in bioenergy research because they specifically hydrolyze xylan, the predominant polysaccharide in the hemicellulose fraction of lignocellulosic biomass. For effective biomass utilization, it is important to understand the mechanism of substrate recognition by these enzymes. Recent studies have shown that the substrate specificities of bacterial and fungal endoxylanases classified into glycoside hydrolase family 30 (GH30) were quite different. While the functional differences have been described, the mechanism of substrate recognition is still unknown. Therefore, a gene encoding a putative GH30 endoxylanase was cloned from Streptomyces turgidiscabies C56, and the recombinant enzyme was purified and characterized. GH30 glucuronoxylan specific xylanase A of Streptomyces turgidiscabies (StXyn30A) showed hydrolytic activity with xylans containing both glucuronic acid and the more common 4-O methyl-glucuronic acid side-chain substitutions but not on linear xylooligosaccharides, suggesting that this enzyme requires the recognition of glucuronic acid side chains for hydrolysis. The StXyn30A limit product structure was analyzed following a secondary beta-xylosidase treatment by thin-layer chromatography and mass spectrometry analysis. The hydrolysis products from both glucuronoxylan and 4-O-methylglucuronoxylan by StXyn30A have these main-chain substitutions on the second xylopyranosyl residue from the reducing end. Because previous structural studies of bacterial GH30 enzymes and molecular modeling of StXyn30A suggested that a conserved arginine residue (Arg296) interacts with the glucuronic acid side-chain carboxyl group, we focused on this residue, which is conserved at subsite -2 of bacterial but not fungal GH30 endoxylanases. To help gain an understanding of the mechanism of how StXyn30A recognizes glucuronic acid substitutions, Arg296 mutant enzymes were studied. The glucuronoxylan hydrolytic activities of Arg296 mutants were significantly reduced in comparison to those of the wild-type enzyme. Furthermore, limit products other than aldotriouronic acid were observed for these Arg296 mutants upon secondary beta-xylosidase treatment. These results indicate that a disruption of the highly conserved Arg296 interaction leads to a decrease of functional specificity in StXyn30A, as indicated by the detection of alternative hydrolysis products. Our studies allow a better understanding of the mechanism of glucuronoxylan recognition and enzyme specificity by bacterial GH30 endoxylanases and provide further definition of these unique enzymes for their potential application in industry.IMPORTANCE Hemicellulases are important enzymes that hydrolyze hemicellulosic polysaccharides to smaller sugars for eventual microbial assimilation and metabolism. These hemicellulases include endoxylanases that cleave the beta-1,4 xylose main chain of xylan, the predominant form of hemicellulose in lignocellulosic biomass. Endoxylanases play an important role in the utilization of plant biomass because in addition to their general utility in xylan degradation, they can also be used to create defined compositions of xylooligosaccharides. For this, it is important to understand the mechanism of substrate recognition. Recent studies have shown that the substrate specificities of bacterial and fungal endoxylanases that are classified into glycoside hydrolase family 30 (GH30) were distinct, but the difference in the mechanisms of substrate recognition is still unknown. We performed characterization and mutagenesis analyses of a new bacterial GH30 endoxylanase for comparison with previously reported fungal GH30 endoxylanases. Our study results in a better understanding of the mechanism of substrate specificity and recognition for bacterial GH30 endoxylanases. The experimental approach and resulting data support the conclusions and provide further definition of the structure and function of GH30 endoxylanases for their application in bioenergy research. PMID- 29180368 TI - Impact of Peat Mining and Restoration on Methane Turnover Potential and Methane Cycling Microorganisms in a Northern Bog. AB - Ombrotrophic peatlands are a recognized global carbon reservoir. Without restoration and peat regrowth, harvested peatlands are dramatically altered, impairing their carbon sink function, with consequences for methane turnover. Previous studies determined the impact of commercial mining on the physicochemical properties of peat and the effects on methane turnover. However, the response of the underlying microbial communities catalyzing methane production and oxidation have so far received little attention. We hypothesize that with the return of Sphagnum spp. postharvest, methane turnover potential and the corresponding microbial communities will converge in a natural and restored peatland. To address our hypothesis, we determined the potential methane production and oxidation rates in natural (as a reference), actively mined, abandoned, and restored peatlands over two consecutive years. In all sites, the methanogenic and methanotrophic population sizes were enumerated using quantitative PCR (qPCR) assays targeting the mcrA and pmoA genes, respectively. Shifts in the community composition were determined using Illumina MiSeq sequencing of the mcrA gene and a pmoA-based terminal restriction fragment length polymorphism (t-RFLP) analysis, complemented by cloning and sequence analysis of the mmoX gene. Peat mining adversely affected methane turnover potential, but the rates recovered in the restored site. The recovery in potential activity was reflected in the methanogenic and methanotrophic abundances. However, the microbial community composition was altered, being more pronounced for the methanotrophs. Overall, we observed a lag between the recovery of the methanogenic/methanotrophic activity and the return of the corresponding microbial communities, suggesting that a longer duration (>15 years) is needed to reverse mining-induced effects on the methane-cycling microbial communities.IMPORTANCE Ombrotrophic peatlands are a crucial carbon sink, but this environment is also a source of methane, an important greenhouse gas. Methane emission in peatlands is regulated by methane production and oxidation catalyzed by methanogens and methanotrophs, respectively. Methane-cycling microbial communities have been documented in natural peatlands. However, less is known of their response to peat mining and of the recovery of the community after restoration. Mining exerts an adverse impact on potential methane production and oxidation rates and on methanogenic and methanotrophic population abundances. Peat mining also induced a shift in the methane-cycling microbial community composition. Nevertheless, with the return of Sphagnum spp. in the restored site after 15 years, methanogenic and methanotrophic activity and population abundance recovered well. The recovery, however, was not fully reflected in the community composition, suggesting that >15 years are needed to reverse mining-induced effects.

AB - Bordetella bronchiseptica, a Gram-negative bacterium, causes chronic respiratory tract infections in a wide variety of mammalian hosts, including humans (albeit rarely). We recently designed Bordetella pertussis and Bordetella parapertussis experimental vaccines based on outer membrane vesicles (OMVs) derived from each pathogen, and we obtained protection against the respective infections in mice. Here, we demonstrated that OMVs derived from virulent-phase B. bronchiseptica (OMVBbvir+) protected mice against sublethal infections with different B. bronchiseptica strains, two isolated from farm animals and one isolated from a human patient. In all infections, we observed that the B. bronchiseptica loads were significantly reduced in the lungs of vaccinated animals; the lung-recovered CFU were decreased by >=4 log units, compared with those detected in the lungs of nonimmunized animals (P < 0.001). In the OMVBbvir+-immunized mice, we detected IgG antibody titers against B. bronchiseptica whole-cell lysates, along with an immune serum having bacterial killing activity that both recognized B. bronchiseptica lipopolysaccharides and polypeptides such as GroEL and outer membrane protein C (OMPc) and demonstrated an essential protective capacity against B. bronchiseptica infection, as detected by passive in vivo transfer experiments. Stimulation of cultured splenocytes from immunized mice with OMVBbvir+ resulted in interleukin 5 (IL-5), gamma interferon (IFN-gamma), and IL 17 production, indicating that the vesicles induced mixed Th2, Th1, and Th17 T cell immune responses. We detected, by adoptive transfer assays, that spleen cells from OMVBbvir+-immunized mice also contributed to the observed protection against B. bronchiseptica infection. OMVs from avirulent-phase B. bronchiseptica and the resulting induced immune sera were also able to protect mice against B. bronchiseptica infection.IMPORTANCEBordetella bronchiseptica, a Gram-negative bacterium, causes chronic respiratory tract infections in a wide variety of mammalian hosts, including humans (albeit rarely). Several vaccines aimed at preventing B. bronchiseptica infection have been developed and used, but a safe effective vaccine is still needed. The significance and relevance of our research lie in the characterization of the OMVs derived from B. bronchiseptica as the source of a new experimental vaccine. We demonstrated here that our formulation based on OMVs derived from virulent-phase B. bronchiseptica (OMVBbvir+) was effective against infections caused by B. bronchiseptica isolates obtained from different hosts (farm animals and a human patient). In vitro and in vivo characterization of humoral and cellular immune responses induced by the OMVBbvir+ vaccine enabled a better understanding of the mechanism of protection necessary to control B. bronchiseptica infection. Here we also demonstrated that OMVs derived from B. bronchiseptica in the avirulent phase and the corresponding induced humoral immune response were able to protect mice from B. bronchiseptica infection. This realization provides the basis for the development of novel vaccines not only against the acute stages of the disease but also against stages of the disease or the infectious cycle in which avirulence factors could play a role. PMID- 29180370 TI - Quantifying the Survival of Multiple Salmonella enterica Serovars in vivo using Massively-parallel Whole Genome Sequencing to Predict Zoonotic Risk. AB - Salmonella enterica is an animal and zoonotic pathogen of worldwide importance. Serovars exist that differ in their host and tissue tropism. Cattle are an important reservoir of human non-typhoidal salmonellosis and contaminated bovine peripheral lymph nodes enter the food chain via ground beef. The relative ability of different serovars to survive within the bovine lymphatic system is poorly understood and constrains the development of control strategies. This problem was addressed by developing a massively-parallel whole genome sequencing method to study mixed-serovar infections in vivoSalmonella serovars differ genetically by naturally occurring single nucleotide polymorphisms (SNPs) in certain genes. It was hypothesised that these SNPs could be used as markers to simultaneously identify serovars in mixed populations and quantify the abundance of each member in a population. The performance of the method was validated in vitro using simulated pools containing up to 11 serovars in varying proportions. It was then applied to study serovar survival in vivo in cattle challenged orally with the same 11 serovars. All the serovars successfully colonised the bovine lymphatic system, including the peripheral lymph nodes, and thus pose a similar risk of zoonosis. This method enables the fate of multiple genetically unmodified strains to be evaluated simultaneously in a single animal. It could be useful in reducing the number of animals required to study multi-strain infections and for testing the cross-protective efficacy of vaccines and treatments. It also has the potential to be applied to diverse bacterial species which possess shared but polymorphic alleles.Importance While some Salmonella serovars are more frequently isolated from lymph nodes rather than the faeces and environment of cattle, the relative ability of serovars to survive within the lymphatic system of cattle remains ill-defined. A sequencing-based method was developed, which used available information from sequenced Salmonella genomes to study the dynamics of mixed-serovar infections in vivo The main advantages of the method include the simultaneous identification and quantification of multiple strains without any genetic modification and minimal animal use. This approach could be used in vaccination trials or in epidemiological surveys where an understanding of the dynamics of closely-related strains of a pathogen in mixed populations could inform the prediction of zoonotic risk and the development of intervention strategies. PMID- 29180371 TI - Ankyrin-Like Protein AnkB Interacts with CatB, Affects Catalase Activity, and Enhances Resistance of Xanthomonas oryzae pv. oryzae and Xanthomonas oryzae pv. oryzicola to Phenazine-1-Carboxylic Acid. AB - Xanthomonas oryzae pv. oryzae, which causes rice bacterial leaf blight, and Xanthomonas oryzae pv. oryzicola, which causes rice bacterial leaf streak, are important plant-pathogenic bacteria. A member of the adaptor protein family, ankyrin protein, has been investigated largely in humans but rarely in plant pathogenic bacteria. In this study, a novel ankyrin-like protein, AnkB, was identified in X. oryzae pv. oryzae and X. oryzae pv. oryzicola. The expression of ankB was significantly upregulated when these bacteria were treated with phenazine-1-carboxylic acid (PCA). ankB is located 58 bp downstream of the gene catB (which encodes a catalase) in both bacteria, and the gene expression of catB and catalase activity were reduced following ankB deletion in X. oryzae pv. oryzae and X. oryzae pv. oryzicola. Furthermore, we demonstrated that AnkB directly interacts with CatB by glutathione S-transferase (GST) pulldown assays. Deletion of ankB increased the sensitivity of X. oryzae pv. oryzae and X. oryzae pv. oryzicola to H2O2 and PCA, decreased bacterial biofilm formation, swimming ability, and exopolysaccharide (EPS) production, and also reduced virulence on rice. Together our results indicate that the ankyrin-like protein AnkB has important and conserved roles in antioxidant systems and pathogenicity in X. oryzae pv. oryzae and X. oryzae pv. oryzicola.IMPORTANCE This study demonstrates that the ankyrin protein AnkB directly interacts with catalase CatB in Xanthomonas oryzae pv. oryzae and Xanthomonas oryzae pv. oryzicola. Ankyrin protein AnkB can affect the gene expression of catB, catalase activity, and sensitivity to H2O2 In Xanthomonas spp., the locations of genes ankB and catB and the amino acid sequence of AnkB are highly conserved. It is suggested that in prokaryotes, AnkB plays a conserved role in the defense against oxidative stress. PMID- 29180372 TI - Quality of Irrigation Water Affects Soil Functionality and Bacterial Community Stability in Response to Heat Disturbance. AB - Anthropogenic activities alter the structure and function of a bacterial community. Furthermore, bacterial communities structured by the conditions the anthropogenic activities present may consequently reduce their stability in response to an unpredicted acute disturbance. The present mesocosm-scale study exposed soil bacterial communities to different irrigation water types, including freshwater, fertilized freshwater, treated wastewater, and artificial wastewater, and evaluated their response to a disturbance caused by heat. These effectors may be considered deterministic and stochastic forces common in agricultural operations of arid and semiarid regions. Bacterial communities under conditions of high mineral and organic carbon availability (artificial wastewater) differed from the native bacterial community and showed a proteobacterial dominance. These bacterial communities had a lower resistance to the heat treatment disturbance than soils under conditions of low resource availability (high-quality treated wastewater or freshwater). The latter soil bacterial communities showed a higher abundance of operational taxonomic units (OTUs) classified as Bacilli These results were elucidated by soil under conditions of high resource availability, which lost higher degrees of functional potential and had a greater bacterial community composition change. However, the functional resilience, after the disturbance ended, was higher under a condition of high resource availability despite the bacterial community composition shift and the decrease in species richness. The functional resilience was directly connected to the high growth rates of certain Bacteroidetes and proteobacterial groups. A high stability was found in samples that supported the coexistence of both resistant OTUs and fast growing OTUs.IMPORTANCE This report presents the results of a study employing a hypothesis-based experimental approach to reveal the forces involved in determining the stability of a soil bacterial community to disturbance. The resultant postdisturbance bacterial community composition dynamics and functionality were analyzed. The paper demonstrates the relatedness of community structure and stability under cultivation conditions prevalent in an arid area under irrigation with water of different qualities. The use of common agricultural practices to demonstrate these features has not been described before. The combination of a fundamental theoretical issue in ecology with common and concerning disturbances caused by agricultural practice makes this study unique. Furthermore, the results of the present study have applicable importance regarding soil conservation, as it enables a better characterization and monitoring of stressed soil bacterial communities and possible intervention to reduce the stress. It will also be of valued interest in coming years, as fresh water scarcity and the use of alternative water sources are expected to rise globally. PMID- 29180373 TI - Generation of Bacteriophage-Insensitive Mutants of Streptococcus thermophilus via an Antisense RNA CRISPR-Cas Silencing Approach. AB - Predation of starter lactic acid bacteria such as Streptococcus thermophilus by bacteriophages is a persistent and costly problem in the dairy industry. CRISPR mediated bacteriophage insensitive mutants (BIMs), while straightforward to generate and verify, can quickly be overcome by mutant phages. The aim of this study was to develop a tool allowing the generation of derivatives of commercial S. thermophilus strains which are resistant to phage attack through a non-CRISPR mediated mechanism, with the objective of generating BIMs exhibiting stable resistance against a range of isolated lytic S. thermophilus phages. To achieve this, standard BIM generation was complemented by the use of the wild-type (WT) strain which had been transformed with an antisense mRNA-generating plasmid (targeting a crucial CRISPR-associated [cas] gene) in order to facilitate the generation of non-CRISPR-mediated BIMs. Phage sensitivity assays suggest that non CRISPR-mediated BIMs exhibit some advantages compared to CRISPR-mediated BIMs derived from the same strain.IMPORTANCE The outlined approach reveals the presence of a powerful host-imposed barrier for phage infection in S. thermophilus Considering the detrimental economic consequences of phage infection in the dairy processing environment, the developed methodology has widespread applications, particularly where other methods may not be practical or effective in obtaining robust, phage-tolerant S. thermophilus starter strains. PMID- 29180375 TI - Formation and Characterization of Early Bacterial Biofilms on Different Wood Typologies Applied in Dairy Production. AB - The main hypothesis of this work was that Sicilian forestry resources are suitable for the production of equipment to be used in cheese making and indigenous milk lactic acid bacteria (LAB) are able to develop stable biofilms providing starter and nonstarter cultures necessary for curd fermentation and cheese ripening, respectively. Hence, the present work was carried out with deproteinized whey to evaluate LAB biofilm formation on different woods derived from tree species grown in Sicily. Microbiological and scanning electron microscopy analyses showed minimal differences in microbial levels and compositions for the neoformed biofilms. The specific investigation of Salmonella spp., Listeria monocytogenes, Escherichia coli, coagulase-positive staphylococci (CPS), and sulfite-reducing anaerobes did not generate any colony for all vats before and after bacterial adhesion. LAB populations dominated all vat surfaces. The highest levels (7.63 log CFU/cm2) were registered for thermophilic cocci. Different colonies were characterized physiologically, biochemically, and genetically (at strain and species levels). Six species within the genera Enterococcus, Lactobacillus, Lactococcus, and Streptococcus were identified. The species most frequently present were Lactobacillus fermentum and Lactococcus lactis LAB found on the surfaces of the wooden vats in this study showed interesting characteristics important for dairy manufacture. To thoroughly investigate the safety of the wooden vat, a test of artificial contamination on new Calabrian chestnut (control wood) vats was carried out. The results showed that LAB represent efficient barriers to the adhesion of the main dairy pathogens, probably due to their acidity and bacteriocin generation.IMPORTANCE This study highlights the importance of using wooden vats for traditional cheese production and provides evidence for the valorization of the Sicilian forest wood resources via the production of dairy equipment. PMID- 29180374 TI - Diazotroph Community Characterization via a High-Throughput nifH Amplicon Sequencing and Analysis Pipeline. AB - The dinitrogenase reductase gene (nifH) is the most widely established molecular marker for the study of nitrogen-fixing prokaryotes in nature. A large number of PCR primer sets have been developed for nifH amplification, and the effective deployment of these approaches should be guided by a rapid, easy-to-use analysis protocol. Bioinformatic analysis of marker gene sequences also requires considerable expertise. In this study, we advance the state of the art for nifH analysis by evaluating nifH primer set performance, developing an improved amplicon sequencing workflow, and implementing a user-friendly bioinformatics pipeline. The developed amplicon sequencing workflow is a three-stage PCR-based approach that uses established technologies for incorporating sample-specific barcode sequences and sequencing adapters. Based on our primer evaluation, we recommend the Ando primer set be used with a modified annealing temperature of 58 degrees C, as this approach captured the largest diversity of nifH templates, including paralog cluster IV/V sequences. To improve nifH sequence analysis, we developed a computational pipeline which infers taxonomy and optionally filters out paralog sequences. In addition, we employed an empirical model to derive optimal operational taxonomic unit (OTU) cutoffs for the nifH gene at the species, genus, and family levels. A comprehensive workflow script named TaxADivA (TAXonomy Assignment and DIVersity Assessment) is provided to ease processing and analysis of nifH amplicons. Our approach is then validated through characterization of diazotroph communities across environmental gradients in beach sands impacted by the Deepwater Horizon oil spill in the Gulf of Mexico, in a peat moss-dominated wetland, and in various plant compartments of a sugarcane field.IMPORTANCE Nitrogen availability often limits ecosystem productivity, and nitrogen fixation, exclusive to prokaryotes, comprises a major source of nitrogen input that sustains food webs. The nifH gene, which codes for the iron protein of the nitrogenase enzyme, is the most widely established molecular marker for the study of nitrogen-fixing microorganisms (diazotrophs) in nature. In this study, a flexible sequencing/analysis pipeline, named TaxADivA, was developed for nifH amplicons produced by Illumina paired-end sequencing, and it enables an inference of taxonomy, performs clustering, and produces output in formats that may be used by programs that facilitate data exploration and analysis. Diazotroph diversity and community composition are linked to ecosystem functioning, and our results advance the phylogenetic characterization of diazotroph communities by providing empirically derived nifH similarity cutoffs for species, genus, and family levels. The utility of our pipeline is validated for diazotroph communities in a variety of ecosystems, including contaminated beach sands, peatland ecosystems, living plant tissues, and rhizosphere soil.

PMID- 29180377 TI - Comparison of Canadian public medication insurance plans and the impact on out-of pocket costs. AB - BACKGROUND: Research from 2006 documented substantial variation in medication coverage for residents across Canada. Since then, some provinces have implemented major medication plan reforms. We aimed to update the information on publicly funded medication insurance plans available across Canada and to compare out-of pocket costs across the country. METHODS: We compared provincial medication insurance plans using data from public websites and other public source documents. Using 2 hypothetical clinical examples, we determined the amount and type of a patient's out-of-pocket costs for 5 different patient subtypes that varied based on medication burden, age and income. RESULTS: Each province offers a plan to all residents. Cost-sharing is employed across all provinces. Some residents must pay a premium to receive insurance or must pay 100% of their medication costs until they reach a deductible amount, above which government funding covers a portion of medication costs. With the scenario of low medication burden (medication cost about $500), out-of-pocket costs ranged from $250 to $2100 for higher-income residents and from $0 to $700 for lower-income residents. With the scenario of high medication burden (medication cost about $1800), the corresponding ranges were $250-$2500 and $0-$1100. The variation was due to province of residence, age and income. INTERPRETATION: Variations in out-of pocket payments continue to exist across the provinces, with some groups facing high expenses. Further work is required to understand the impact of different cost-sharing mechanisms, develop policies to limit out-of-pocket expenses and improve provincial drug plans. PMID- 29180378 TI - Cationic gas-filled microbubbles for ultrasound-based nucleic acids delivery. AB - The use of ultrasound has gained great interest for nucleic acids delivery. Ultrasound can reach deep tissues in non-invasive manner. The process of sonoporation is based on the use of low-frequency ultrasound combined with gas filled microbubbles (MBs) allowing an improved delivery of molecules including nucleic acids in the insonified tissue. For in vivo gene transfer, the engineering of cationic MBs is essential for creating strong electrostatic interactions between MBs and nucleic acids leading to their protection against nucleases degradation and high concentration within the target tissue. Cationic MBs must be stable enough to withstand nucleic acids interaction, have a good size distribution for in vivo administration, and enough acoustic activity to be detected by echography. This review aims to summarize the basic principles of ultrasound-based delivery and new knowledge acquired in these recent years about this method. A focus is made on gene delivery by discussing reported studies made with cationic MBs including ours. They have the ability for efficient delivery of plasmid DNA (pDNA), mRNA or siRNA. Last, we discuss about the key challenges that have to be faced for a fine use of this delivery system. PMID- 29180379 TI - Selection of internal references for qRT-PCR assays of human hepatocellular carcinoma cell lines. AB - Selecting internal references is important for normalizing the loading quantity of samples in quantitative reverse-transcription PCR (qRT-PCR). In the present study, a systematic evaluation of reference genes among nine hepatocellular carcinoma (HCC) cell lines was conducted. After screening the microarray assay data of ten HCC cell lines, 19 candidate reference genes were preselected and then evaluated by qRT-PCR, together with ACTB, GAPDH, HPRT1 and TUBB The expression evenness of these candidate genes was evaluated using RefFinder. The stabilities of the reference genes were further evaluated under different experimental perturbations in Huh-7 and MHCC-97L, and the applicability of the reference genes was assessed by measuring the mRNA expression of CCND1, CCND3, CDK4 and CDK6 under sorafenib treatment in Huh-7. Results showed that TFG and SFRS4 are among the most reliable reference genes, and ACTB ranks third and acts quite well as a classical choice, whereas GAPDH, HPRT1 and TUBB are not proper reference genes in qRT-PCR assays among the HCC cell lines. SFRS4, YWHAB, SFRS4 and CNPY3 are the most stable reference genes of the MHCC-97L under the perturbations of chemotherapy, oxidative stress, starvation and hypoxia respectively, whereas YWHAB is the most stable one of Huh-7 under all perturbations. GAPDH is recommended as a reference gene under chemotherapy perturbations. YWHAB and UBE2B, TMED2 and TSFM, and GAPDH and TSFM are the two best reference genes under oxidative stress, starvation and hypoxia perturbations respectively. TSFM is stable in both cell lines across all the perturbations. PMID- 29180380 TI - OsmiR396d Affects Gibberellin and Brassinosteroid Signaling to Regulate Plant Architecture in Rice. AB - Genetic improvement of plant architecture is one of the strategies for increasing the yield potential of rice (Oryza sativa). Although great progress has been made in the understanding of plant architecture regulation, the precise mechanism is still an urgent need to be revealed. Here, we report that over-expression of OsMIR396d in rice results in semidwarf and increased leaf angle, a typical phenotype of brassinosteroid (BR) enhanced mutant. OsmiR396d is involved in the interaction network of BR and gibberellin (GA) signaling. In OsMIR396d over expression plants, BR signaling was enhanced. In contrast, both the signaling and biosynthesis of GA were impaired. BRASSINAZOLE-RESISTANT1, a core transcription activator of BR signaling, directly promoted the accumulation of OsmiR396d, which controlled BR response and GA biosynthesis by regulating the expression of different target genes respectively. GROWTH REGULATING FACTOR 6, one of OsmiR396d targets, participated in GA biosynthesis and signal transduction but was not directly involved in BR signaling. This study provides a new insight into the understanding of interaction between BR and GA from multiple levels on controlling plant architecture. PMID- 29180382 TI - What to do about the Canadian Resident Matching Service. PMID- 29180381 TI - Extracellular ATP Acts on Jasmonate Signaling to Reinforce Plant Defense. AB - Damaged cells send various signals to stimulate defense responses. Recent identification and genetic studies of the plant purinoceptor, P2K1 (also known as DORN1), have demonstrated that extracellular ATP is a signal involved in plant stress responses, including wounding, perhaps to evoke plant defense. However, it remains largely unknown how extracellular ATP induces plant defense responses. Here, we demonstrate that extracellular ATP induces plant defense mediated through activation of the intracellular signaling of jasmonate (JA), a well characterized defense hormone. In Arabidopsis (Arabidopsis thaliana) leaves, ATP pretreatment induced resistance against the necrotrophic fungus, Botrytis cinerea The induced resistance was enhanced in the P2K1 receptor overexpression line, but reduced in the receptor mutant, dorn1-3 Mining the transcriptome data revealed that ATP induces a set of JA-induced genes. In addition, the P2K1-associated coexpression network contains defense-related genes, including those encoding jasmonate ZIM-domain (JAZ) proteins, which play key roles as repressors of JA signaling. We examined whether extracellular ATP impacts the stability of JAZ1 in Arabidopsis. The results showed that the JAZ1 stability decreased in response to ATP addition in a proteasome-dependent manner. This reduction required intracellular signaling via second messengers-cytosolic calcium, reactive oxygen species, and nitric oxide. Interestingly, the ATP-induced JAZ1 degradation was attenuated in the JA receptor mutant, coi1, but not in the JA biosynthesis mutant, aos, or upon addition of JA biosynthesis inhibitors. Immunoprecipitation analysis demonstrated that ATP increases the interaction between COI1 and JAZ1, suggesting direct cross talk between extracellular ATP and JA in intracellular signaling events. Taken together, these results suggest that extracellular ATP signaling directly impacts the JA signaling pathway to maximize plant defense responses. PMID- 29180383 TI - Comparative risk of incident venous thromboembolism in patients with inflammatory bowel disease initiating tumour necrosis factor-alpha inhibitors or nonbiologic agents: a cohort study. AB - BACKGROUND: Inflammatory bowel disease (IBD) increases the risk of venous thromboembolism (VTE) by 2 to 3 times. We compared the reduction in risk of incident VTE associated with use of tumour necrosis factor-alpha (TNF-alpha) inhibitors versus nonbiologic immunomodulatory agents in patients with IBD. METHODS: This observational cohort study used data from public (Medicaid, 2000 2010; Medicare, 2007-2013) and private (Optum Clinformatics, 2004-2013) health insurance programs in the United States. We included a total of 21 671 patients who had IBD without a prior diagnosis of cancer or VTE. The exposure of interest was treatment initiation with TNF-alpha inhibitor or nonbiologic (azathioprine, mercaptopurine, methotrexate, cyclosporine). The outcome of interest was admission to hospital with VTE as the principal diagnosis. We used Cox proportional hazard regression models to estimate hazard ratios (HRs) separately for each database after risk adjustment for more than 50 covariables using propensity score fine stratification. We used inverse variance meta-analytic methods to pool the adjusted HRs across the 3 databases. RESULTS: We included a total of 5173 patients who started TNF-alpha inhibitor therapy (1439 in the Medicaid database, 1480 in Medicare and 2254 in Optum Clinformatics) and 16 498 who initiated a nonbiologic agent (5041 in Medicaid, 5166 in Medicare, 6291 in Optum Clinformatics). The adjusted pooled HR for VTE risk with TNF-alpha inhibitor versus a nonbiologic agent was 0.78 (95% confidence interval [CI] 0.60 to 1.02). The HR was lower in patients with Crohn disease (pooled HR 0.62, 95% CI 0.44 to 0.86) and younger patients (18-44 yr; pooled HR 0.55, 95% CI 0.34 to 0.87). INTERPRETATION: We did not find a statistically significant association between risk of VTE and use of TNF-alpha inhibitors, relative to nonbiologics, in patients with IBD overall. However, an association was evident for patients younger than 45 years and those with Crohn disease.

AB - Pathogenetic markers of diabetic kidney disease (DKD) progression to ESRD are lacking. We characterized the prognostic value of histologic findings in DKD for time to ESRD in native kidney specimens from biopsies performed from 1995 to 2011 with diabetic glomerulosclerosis as the only glomerular disease diagnosis (n=109). Biopsy specimens were analyzed according to standard methods, including determination of diabetic nephropathy class, as defined by the Renal Pathology Society. Clinical data were extracted from electronic medical records. We used competing risk models, with death as the competing risk, to estimate subdistribution hazard ratios (HRs) for ESRD. All multivariable models included age, sex, black race, baseline eGFR, and baseline proteinuria. Pathologic characteristics achieving P<0.1 were added into successively complex models. ESRD occurred in 56% of patients, and 26% of patients died before reaching ESRD. In univariate analyses, diabetic nephropathy class was not statistically significant in predicting time to ESRD. The final multivariable model (n=106) showed a borderline association between mild mesangial expansion and decreased risk for ESRD (subdistribution HR, 0.64; 95% confidence interval, 0.40 to 1.00). Poor prognostic factors in the final model included segmental sclerosis and extracapillary hypercellularity (subdistribution HR, 2.04; 95% confidence interval, 1.36 to 3.05; and subdistribution HR, 2.21; 95% confidence interval, 1.19 to 4.11, respectively). In conclusion, we identified segmental sclerosis and extracapillary hypercellularity as novel, poor prognostic indicators of time from DKD to ESRD. Whether these indicators represent a distinct pathogenetic phenotype of DKD will require a large study with a broad spectrum of disease severity. PMID- 29180394 TI - Redirecting TGF-beta Signaling through the beta-Catenin/Foxo Complex Prevents Kidney Fibrosis. AB - TGF-beta is a key profibrotic factor, but targeting TGF-beta to prevent fibrosis also abolishes its protective anti-inflammatory effects. Here, we investigated the hypothesis that we can redirect TGF-beta signaling by preventing downstream profibrotic interaction of beta-catenin with T cell factor (TCF), thereby enhancing the interaction of beta-catenin with Foxo, a transcription factor that controls differentiation of TGF-beta induced regulatory T cells (iTregs), and thus, enhance anti-inflammatory effects of TGF-beta In iTregs derived from EL4 T cells treated with recombinant human TGF-beta1 (rhTGF-beta1) in vitro, inhibition of beta-catenin/TCF transcription with ICG-001 increased Foxp3 expression, interaction of beta-catenin and Foxo1, binding of Foxo1 to the Foxp3 promoter, and Foxo transcriptional activity. Moreover, the level of beta-catenin expression positively correlated with the level of Foxo1 binding to the Foxp3 promoter and Foxo transcriptional activity. T cell fate mapping in Foxp3gfp Ly5.1/5.2 mice revealed that coadministration of rhTGF-beta1 and ICG-001 further enhanced the expansion of iTregs and natural Tregs observed with rhTGF-beta1 treatment alone. Coadministration of rhTGF-beta1 with ICG-001 also increased the number of Tregs and reduced inflammation and fibrosis in the kidney fibrosis models of unilateral ureteric obstruction and ischemia-reperfusion injury. Notably, ICG-001 prevented the fibrosis in distant organs (lung and liver) caused by rhTGF-beta1. Together, our results show that diversion of beta-catenin from TCF- to Foxo-mediated transcription inhibits the beta-catenin/TCF-mediated profibrotic effects of TGF beta while enhancing the beta-catenin/Foxo-mediated anti-inflammatory effects. Targeting beta-catenin/Foxo may be a novel therapeutic strategy in the treatment of fibrotic diseases that lead to organ failure. PMID- 29180396 TI - The UMOD Locus: Insights into the Pathogenesis and Prognosis of Kidney Disease. AB - The identification of genetic factors associated with kidney disease has the potential to provide critical insights into disease mechanisms. Genome-wide association studies have uncovered genomic regions associated with renal function metrics and risk of CKD. UMOD is among the most outstanding loci associated with CKD in the general population, because it has a large effect on eGFR and CKD risk that is consistent across different ethnic groups. The relevance of UMOD for CKD is clear, because the encoded protein, uromodulin (Tamm-Horsfall protein), is exclusively produced by the kidney tubule and has specific biochemical properties that mediate important functions in the kidney and urine. Rare mutations in UMOD are the major cause of autosomal dominant tubulointerstitial kidney disease, a condition that leads to CKD and ESRD. In this brief review, we use the UMOD paradigm to describe how population genetic studies can yield insight into the pathogenesis and prognosis of kidney diseases.

AB - Tamm-Horsfall protein (THP), also known as uromodulin, is a kidney-specific protein produced by cells of the thick ascending limb of the loop of Henle. Although predominantly secreted apically into the urine, where it becomes highly polymerized, THP is also released basolaterally, toward the interstitium and circulation, to inhibit tubular inflammatory signaling. Whether, through this latter route, THP can also regulate the function of renal interstitial mononuclear phagocytes (MPCs) remains unclear, however. Here, we show that THP is primarily in a monomeric form in human serum. Compared with wild-type mice, THP-/ mice had markedly fewer MPCs in the kidney. A nonpolymerizing, truncated form of THP stimulated the proliferation of human macrophage cells in culture and partially restored the number of kidney MPCs when administered to THP-/- mice. Furthermore, resident renal MPCs had impaired phagocytic activity in the absence of THP. After ischemia-reperfusion injury, THP-/- mice, compared with wild-type mice, exhibited aggravated injury and an impaired transition of renal macrophages toward an M2 healing phenotype. However, treatment of THP-/- mice with truncated THP after ischemia-reperfusion injury mitigated the worsening of AKI. Taken together, our data suggest that interstitial THP positively regulates mononuclear phagocyte number, plasticity, and phagocytic activity. In addition to the effect of THP on the epithelium and granulopoiesis, this new immunomodulatory role could explain the protection conferred by THP during AKI. PMID- 29180397 TI - ApoL1 Overexpression Drives Variant-Independent Cytotoxicity. AB - Coding variants in the APOL1 gene are associated with kidney diseases in African ancestral populations; yet, the underlying biologic mechanisms remain uncertain. Variant-dependent autophagic and cytotoxic cell death have been proposed as pathogenic pathways mediating kidney injury. To examine this possibility, we conditionally expressed APOL1-G0 (reference), -G1, and -G2 (variants) using a tetracycline-regulated system in HEK293 cells. Autophagy was monitored biochemically and cell death was measured using multiple assays. We measured intracellular Na+ and K+ content with atomic absorption spectroscopy and APOL1 dependent currents with whole-cell patch clamping. Neither reference nor variant APOL1s induced autophagy. At high expression levels, APOL1-G0, -G1, and -G2 inserted into the plasma membrane and formed pH-sensitive cation channels, causing collapse of cellular Na+ and K+ gradients, phosphorylation of p38 mitogen activated protein kinase, and cell death, without variant-dependent differences. APOL1-G0 and -G2 exhibited similar channel properties in whole-cell patch clamp experiments. At low expression levels, neither reference nor variant APOL1s localized on the plasma membrane, Na+ and K+ gradients were maintained, and cells remained viable. Our results indicate that APOL1-mediated pore formation is critical for the trypanolytic activity of APOL1 and drives APOL1-mediated cytotoxicity in overexpression systems. The absence of cytotoxicity at physiologic expression levels suggests variant-dependent intracellular K+ loss and cytotoxicity does not drive kidney disease progression.

AB - Thalassemias are a heterogeneous group of red blood cell disorders, considered a major cause of morbidity and mortality among genetic diseases. However, there is still no universally available cure for thalassemias. The underlying basis of thalassemia pathology is the premature apoptotic destruction of erythroblasts causing ineffective erythropoiesis. In beta-thalassemia, beta-globin synthesis is reduced causing alpha-globin accumulation. Unpaired globin chains, with heme attached to them, accumulate in thalassemic erythroblasts causing oxidative stress and the premature cell death. We hypothesize that in beta-thalassemia heme oxygenase (HO) 1 could play a pathogenic role in the development of anemia and ineffective erythropoiesis. To test this hypothesis, we exploited a mouse model of beta-thalassemia intermedia, Th3/+ We observed that HO inhibition using tin protoporphyrin IX (SnPP) decreased heme-iron recycling in the liver and ameliorated anemia in the Th3/+ mice. SnPP administration led to a decrease in erythropoietin and increase in hepcidin serum levels, changes that were accompanied by an alleviation of ineffective erythropoiesis in Th3/+ mice. Additionally, the bone marrow from Th3/+ mice treated with SnPP exhibited decreased heme catabolism and diminished iron release as well as reduced apoptosis. Our results indicate that the iron released from heme because of HO activity contributes to the pathophysiology of thalassemia. Therefore, new therapies that suppress heme catabolism may be beneficial in ameliorating the anemia and ineffective erythropoiesis in thalassemias.

PMID- 29180401 TI - Predicting phenological shifts in a changing climate. AB - Phenological shifts constitute one of the clearest manifestations of climate warming. Advanced emergence is widely reported in high-latitude ectotherms, but a significant number of species exhibit delayed, or no change in, emergence. Here we present a mechanistic theoretical framework that reconciles these disparate observations and predicts population-level phenological patterns based solely on data on temperature responses of the underlying life history traits. Our model, parameterized with data from insects at different latitudes, shows that peak abundance occurs earlier in the year when warming increases the mean environmental temperature, but is delayed when warming increases the amplitude of seasonal fluctuations. We find that warming does not necessarily lead to a longer activity period in high-latitude species because it elevates summer temperatures above the upper limit for reproduction and development. Our findings both confirm and confound expectations for ectotherm species affected by climate warming: an increase in the mean temperature is more detrimental to low-latitude species adapted to high mean temperatures and low-amplitude seasonal fluctuations; an increase in seasonal fluctuations is more detrimental to high-latitude species adapted to low mean temperatures and high-amplitude fluctuations. PMID- 29180399 TI - Diminished microRNA-29b level is associated with BRD4-mediated activation of oncogenes in cutaneous T-cell lymphoma. AB - MicroRNA (miRNA) dysregulation is a hallmark of cutaneous T-cell lymphoma (CTCL), an often-fatal malignancy of skin-homing CD4+ T cells for which there are few effective therapies. The role of microRNAs (miRs) in controlling epigenetic modifier-dependent transcriptional regulation in CTCL is unknown. In this study, we characterize a novel miR dysregulation that contributes to overexpression of the epigenetic reader bromodomain-containing protein 4 (BRD4). We used patient CD4+ T cells to show diminished levels of miR-29b compared with healthy donor cells. Patient cells and miR-29b-/- mouse cells revealed an inverse relationship between miR-29b and BRD4, the latter of which is overexpressed in these cells. Chromatin immunoprecipitation and sequencing analysis revealed increased genome wide BRD4 occupancy at promoter and enhancer regions in CD4+ T cells from CTCL patients. The cumulative result of BRD4 binding was increased expression of tumor associated genes such as NOTCH1 and RBPJ, as well as the interleukin-15 (IL-15) receptor complex, the latter enhancing IL-15 autocrine signaling. Furthermore, we confirm the in vivo relevance of this pathway in our IL-15 transgenic mouse model of CTCL by showing that interference with BRD4-mediated pathogenesis, either by restoring miR-29b levels via bortezomib treatment or by directly inhibiting BRD4 binding via JQ1 treatment, prevents progression of CTCL. We describe a novel oncogenic pathway featuring IL-15, miR-29b, and BRD4 in CTCL and suggest targeting of these components as a potentially effective therapy for CTCL patients. PMID- 29180402 TI - Fishnet model for failure probability tail of nacre-like imbricated lamellar materials. AB - Nacre, the iridescent material of the shells of pearl oysters and abalone, consists mostly of aragonite (a form of CaCO3), a brittle constituent of relatively low strength ([Formula: see text]10 MPa). Yet it has astonishing mean tensile strength ([Formula: see text]150 MPa) and fracture energy ([Formula: see text]350 to 1,240 J/m2). The reasons have recently become well understood: (i) the nanoscale thickness ([Formula: see text]300 nm) of nacre's building blocks, the aragonite lamellae (or platelets), and (ii) the imbricated, or staggered, arrangement of these lamellea, bound by biopolymer layers only [Formula: see text]25 nm thick, occupying [Formula: see text] of volume. These properties inspire manmade biomimetic materials. For engineering applications, however, the failure probability of [Formula: see text] is generally required. To guarantee it, the type of probability density function (pdf) of strength, including its tail, must be determined. This objective, not pursued previously, is hardly achievable by experiments alone, since [Formula: see text] tests of specimens would be needed. Here we outline a statistical model of strength that resembles a fishnet pulled diagonally, captures the tail of pdf of strength and, importantly, allows analytical safety assessments of nacreous materials. The analysis shows that, in terms of safety, the imbricated lamellar structure provides a major additional advantage-~10% strength increase at tail failure probability [Formula: see text] and a 1 to 2 orders of magnitude tail probability decrease at fixed stress. Another advantage is that a high scatter of microstructure properties diminishes the strength difference between the mean and the probability tail, compared with the weakest link model. These advantages of nacre-like materials are here justified analytically and supported by millions of Monte Carlo simulations.

PMID- 29180403 TI - SUMOylation and ubiquitination reciprocally regulate alpha-synuclein degradation and pathological aggregation. AB - alpha-Synuclein accumulation is a pathological hallmark of Parkinson's disease (PD). Ubiquitinated alpha-synuclein is targeted to proteasomal or lysosomal degradation. Here, we identify SUMOylation as a major mechanism that counteracts ubiquitination by different E3 ubiquitin ligases and regulates alpha-synuclein degradation. We report that PIAS2 promotes SUMOylation of alpha-synuclein, leading to a decrease in alpha-synuclein ubiquitination by SIAH and Nedd4 ubiquitin ligases, and causing its accumulation and aggregation into inclusions. This was associated with an increase in alpha-synuclein release from the cells. A SUMO E1 inhibitor, ginkgolic acid, decreases alpha-synuclein levels by relieving the inhibition exerted on alpha-synuclein proteasomal degradation. alpha Synuclein disease mutants are more SUMOylated compared with the wild-type protein, and this is associated with increased aggregation and inclusion formation. We detected a marked increase in PIAS2 expression along with SUMOylated alpha-synuclein in PD brains, providing a causal mechanism underlying the up-regulation of alpha-synuclein SUMOylation in the disease. We also found a significant proportion of Lewy bodies in nigral neurons containing SUMO1 and PIAS2. Our observations suggest that SUMOylation of alpha-synuclein by PIAS2 promotes alpha-synuclein aggregation by two mutually reinforcing mechanisms. First, it has a direct proaggregatory effect on alpha-synuclein. Second, SUMOylation facilitates alpha-synuclein aggregation by blocking its ubiquitin dependent degradation pathways and promoting its accumulation. Therefore, inhibitors of alpha-synuclein SUMOylation provide a strategy to reduce alpha synuclein levels and possibly aggregation in PD. PMID- 29180405 TI - Hydraulic fracturing near domestic groundwater wells. AB - Hydraulic fracturing operations are generating considerable discussion about their potential to contaminate aquifers tapped by domestic groundwater wells. Groundwater wells located closer to hydraulically fractured wells are more likely to be exposed to contaminants derived from on-site spills and well-bore failures, should they occur. Nevertheless, the proximity of hydraulic fracturing operations to domestic groundwater wells is unknown. Here, we analyze the distance between domestic groundwater wells (public and self-supply) constructed between 2000 and 2014 and hydraulically fractured wells stimulated in 2014 in 14 states. We show that 37% of all recorded hydraulically fractured wells stimulated during 2014 exist within 2 km of at least one recently constructed (2000-2014) domestic groundwater well. Furthermore, we identify 11 counties where most ([Formula: see text]50%) recorded domestic groundwater wells exist within 2 km of one or more hydraulically fractured wells stimulated during 2014. Our findings suggest that understanding how frequently hydraulic fracturing operations impact groundwater quality is of widespread importance to drinking water safety in many areas where hydraulic fracturing is common. We also identify 236 counties where most recorded domestic groundwater wells exist within 2 km of one or more recorded oil and gas wells producing during 2014. Our analysis identifies hotspots where both conventional and unconventional oil and gas wells frequently exist near recorded domestic groundwater wells that may be targeted for further water-quality monitoring. PMID- 29180406 TI - Coupled European and Greenland last glacial dust activity driven by North Atlantic climate. AB - Centennial-scale mineral dust peaks in last glacial Greenland ice cores match the timing of lowest Greenland temperatures, yet little is known of equivalent changes in dust-emitting regions, limiting our understanding of dust-climate interaction. Here, we present the most detailed and precise age model for European loess dust deposits to date, based on 125 accelerator mass spectrometry 14C ages from Dunaszekcso, Hungary. The record shows that variations in glacial dust deposition variability on centennial-millennial timescales in east central Europe and Greenland were synchronous within uncertainty. We suggest that precipitation and atmospheric circulation changes were likely the major influences on European glacial dust activity and propose that European dust emissions were modulated by dominant phases of the North Atlantic Oscillation, which had a major influence on vegetation and local climate of European dust source regions. PMID- 29180407 TI - Glycosyltransferase MDR1 assembles a dividing ring for mitochondrial proliferation comprising polyglucan nanofilaments. AB - Mitochondria, which evolved from a free-living bacterial ancestor, contain their own genomes and genetic systems and are produced from preexisting mitochondria by binary division. The mitochondrion-dividing (MD) ring is the main skeletal structure of the mitochondrial division machinery. However, the assembly mechanism and molecular identity of the MD ring are unknown. Multi-omics analysis of isolated mitochondrial division machinery from the unicellular alga Cyanidioschyzon merolae revealed an uncharacterized glycosyltransferase, MITOCHONDRION-DIVIDING RING1 (MDR1), which is specifically expressed during mitochondrial division and forms a single ring at the mitochondrial division site. Nanoscale imaging using immunoelectron microscopy and componential analysis demonstrated that MDR1 is involved in MD ring formation and that the MD ring filaments are composed of glycosylated MDR1 and polymeric glucose nanofilaments. Down-regulation of MDR1 strongly interrupted mitochondrial division and obstructed MD ring assembly. Taken together, our results suggest that MDR1 mediates the synthesis of polyglucan nanofilaments that assemble to form the MD ring. Given that a homolog of MDR1 performs similar functions in chloroplast division, the establishment of MDR1 family proteins appears to have been a singular, crucial event for the emergence of endosymbiotic organelles.

PMID- 29180408 TI - In situ modeling of multimodal floral cues attracting wild pollinators across environments. AB - With more than 80% of flowering plant species specialized for animal pollination, understanding how wild pollinators utilize resources across environments can encourage efficient planting and maintenance strategies to maximize pollination and establish resilience in the face of environmental change. A fundamental question is how generalist pollinators recognize "flower objects" in vastly different ecologies and environments. On one hand, pollinators could employ a specific set of floral cues regardless of environment. Alternatively, wild pollinators could recognize an exclusive signature of cues unique to each environment or flower species. Hoverflies, which are found across the globe, are one of the most ecologically important alternative pollinators after bees and bumblebees. Here, we have exploited their cosmopolitan status to understand how wild pollinator preferences change across different continents. Without employing any a priori assumptions concerning the floral cues, we measured, predicted, and finally artificially recreated multimodal cues from individual flowers visited by hoverflies in three different environments (hemiboreal, alpine, and tropical) using a field-based methodology. We found that although "flower signatures" were unique for each environment, some multimodal lures were ubiquitously attractive, despite not carrying any reward, or resembling real flowers. While it was unexpected that cue combinations found in real flowers were not necessary, the robustness of our lures across insect species and ecologies could reflect a general strategy of resource identification for generalist pollinators. Our results provide insights into how cosmopolitan pollinators such as hoverflies identify flowers and offer specific ecologically based cues and strategies for attracting pollinators across diverse environments.

PMID- 29180410 TI - Smek1/2 is a nuclear chaperone and cofactor for cleaved Wnt receptor Ryk, regulating cortical neurogenesis. AB - The receptor-like tyrosine kinase (Ryk), a Wnt receptor, is important for cell fate determination during corticogenesis. During neuronal differentiation, the Ryk intracellular domain (ICD) is cleaved. Cleavage of Ryk and nuclear translocation of Ryk-ICD are required for neuronal differentiation. However, the mechanism of translocation and how it regulates neuronal differentiation remain unclear. Here, we identified Smek1 and Smek2 as Ryk-ICD partners that regulate its nuclear localization and function together with Ryk-ICD in the nucleus through chromatin recruitment and gene transcription regulation. Smek1/2 double knockout mice displayed pronounced defects in the production of cortical neurons, especially interneurons, while the neural stem cell population increased. In addition, both Smek and Ryk-ICD bound to the Dlx1/2 intergenic regulator element and were involved in its transcriptional regulation. These findings demonstrate a mechanism of the Ryk signaling pathway in which Smek1/2 and Ryk-ICD work together to mediate neural cell fate during corticogenesis.

PMID- 29180412 TI - Membrane targeting of inhibitory Smads through palmitoylation controls TGF beta/BMP signaling. AB - TGF-beta/BMP (bone morphogenetic protein) signaling pathways play conserved roles in controlling embryonic development, tissue homeostasis, and stem cell regulation. Inhibitory Smads (I-Smads) have been shown to negatively regulate TGF beta/BMP signaling by primarily targeting the type I receptors for ubiquitination and turnover. However, little is known about how I-Smads access the membrane to execute their functions. Here we show that Dad, the Drosophila I-Smad, associates with the cellular membrane via palmitoylation, thereby targeting the BMP type I receptor for ubiquitination. By performing systematic biochemistry assays, we characterized the specific cysteine (Cys556) essential for Dad palmitoylation and membrane association. Moreover, we demonstrate that dHIP14, a Drosophila palmitoyl acyl-transferase, catalyzes Dad palmitoylation, thereby inhibiting efficient BMP signaling. Thus, our findings uncover a modification of the inhibitory Smads that controls TGF-beta/BMP signaling activity.

PMID- 29180416 TI - Fluid-driven origami-inspired artificial muscles. AB - Artificial muscles hold promise for safe and powerful actuation for myriad common machines and robots. However, the design, fabrication, and implementation of artificial muscles are often limited by their material costs, operating principle, scalability, and single-degree-of-freedom contractile actuation motions. Here we propose an architecture for fluid-driven origami-inspired artificial muscles. This concept requires only a compressible skeleton, a flexible skin, and a fluid medium. A mechanical model is developed to explain the interaction of the three components. A fabrication method is introduced to rapidly manufacture low-cost artificial muscles using various materials and at multiple scales. The artificial muscles can be programed to achieve multiaxial motions including contraction, bending, and torsion. These motions can be aggregated into systems with multiple degrees of freedom, which are able to produce controllable motions at different rates. Our artificial muscles can be driven by fluids at negative pressures (relative to ambient). This feature makes actuation safer than most other fluidic artificial muscles that operate with positive pressures. Experiments reveal that these muscles can contract over 90% of their initial lengths, generate stresses of ~600 kPa, and produce peak power densities over 2 kW/kg-all equal to, or in excess of, natural muscle. This architecture for artificial muscles opens the door to rapid design and low-cost fabrication of actuation systems for numerous applications at multiple scales, ranging from miniature medical devices to wearable robotic exoskeletons to large deployable structures for space exploration. PMID- 29180415 TI - WhiB6 regulation of ESX-1 gene expression is controlled by a negative feedback loop in Mycobacterium marinum. AB - ESX (ESAT-6 system) export systems play diverse roles across mycobacterial species. Interestingly, genetic disruption of ESX systems in different species does not result in an accumulation of protein substrates in the mycobacterial cell. However, the mechanisms underlying this observation are elusive. We hypothesized that the levels of ESX substrates were regulated by a feedback control mechanism, linking the levels of substrates to the secretory status of ESX systems. To test this hypothesis, we used a combination of genetic, transcriptomic, and proteomic approaches to define export-dependent mechanisms regulating the levels of ESX-1 substrates in Mycobacterium marinum WhiB6 is a transcription factor that regulates expression of genes encoding ESX-1 substrates. We found that, in the absence of the genes encoding conserved membrane components of the ESX-1 system, the expression of the whiB6 gene and genes encoding ESX-1 substrates were reduced. Accordingly, the levels of ESX-1 substrates were decreased, and WhiB6 was not detected in M. marinum strains lacking genes encoding ESX-1 components. We demonstrated that, in the absence of EccCb1, a conserved ESX-1 component, substrate gene expression was restored by constitutive, but not native, expression of the whiB6 gene. Finally, we found that the loss of WhiB6 resulted in a virulent M. marinum strain with reduced ESX 1 secretion. Together, our findings demonstrate that the levels of ESX-1 substrates in M. marinum are fine-tuned by negative feedback control, linking the expression of the whiB6 gene to the presence, not the functionality, of the ESX-1 membrane complex.

PMID- 29180417 TI - SNX8 mediates IFNgamma-triggered noncanonical signaling pathway and host defense against Listeria monocytogenes. AB - IFNgamma is a cytokine that plays a key role in host defense against intracellular pathogens. In addition to the canonical JAK-STAT1 pathway, IFNgamma also activates an IKKbeta-mediated noncanonical signaling pathway that is essential for induction of a subset of downstream effector genes. The molecular mechanisms and functional significance of this IFNgamma-triggered noncanonical pathway remains enigmatic. Here, we identified sorting nexin 8 (SNX8) as an important component of the IFNgamma-triggered noncanonical signaling pathway. SNX8-deficiency impaired IFNgamma-triggered induction of a subset of downstream genes. Snx8-/- mice infected with Listeria monocytogenes exhibited lower serum cytokine levels and higher bacterial loads in the livers and spleens, resulting in higher lethality. Mechanistically, SNX8 interacted with JAK1 and IKKbeta and promoted their association. IFNgamma induced JAK1-mediated phosphorylation of SNX8 at Tyr95 and Tyr126, which promoted the recruitment of IKKbeta to the JAK1 complex. SNX8-deficiency impaired IFNgamma-induced oligomerization and autophosphorylation of IKKbeta at Ser177, which is critical for selective induction of downstream genes. Our findings suggest that SNX8 acts as a link for IFNgamma-triggered noncanonical signaling pathway, which induces a subset of downstream genes important for host defense against L. monocytogenes infection. PMID- 29180419 TI - Chiral intertwined spirals and magnetic transition dipole moments dictated by cylinder helicity. AB - The presence of anomalous chirality in a roll of graphitic carbon sheets has been recognized since the discovery of carbon nanotubes, which are becoming available in higher quantities through the isolation of chiral single-wall congeners with high purity. Exploration of the properties arising from cylinder chirality is expected to expand the scope of tubular entities in the future. By studying molecular fragments of helical carbon nanotubes, we herein reveal interesting properties that arise from this chirality. The chirality of nanoscale cylinders resulted in chirality of larger dimensions in the form of a double-helix assembly. Cylinder chirality in solution gave rise to a large dissymmetry factor of metal-free entities in circular polarized luminescence. Theoretical investigations revealed the pivotal role of cylindrical shapes in enhancing magnetic dipole transition moments to yield extreme rotatory strength. Unique effects of cylinder chirality in this study may prompt the development of tubular entities, for instance, toward chiroptical applications. PMID- 29180420 TI - Structures and enzymatic mechanisms of phycobiliprotein lyases CpcE/F and PecE/F. AB - The light-harvesting phycobilisome in cyanobacteria and red algae requires the lyase-catalyzed chromophorylation of phycobiliproteins. There are three functionally distinct lyase families known. The heterodimeric E/F type is specific for attaching bilins covalently to alpha-subunits of phycocyanins and phycoerythrins. Unlike other lyases, the lyase also has chromophore-detaching activity. A subclass of the E/F-type lyases is, furthermore, capable of chemically modifying the chromophore. Although these enzymes were characterized >25 y ago, their structures remained unknown. We determined the crystal structure of the heterodimer of CpcE/F from Nostoc sp. PCC7120 at 1.89-A resolution. Both subunits are twisted, crescent-shaped alpha-solenoid structures. CpcE has 15 and CpcF 10 helices. The inner (concave) layer of CpcE (helices h2, 4, 6, 8, 10, 12, and 14) and the outer (convex) layer of CpcF (h16, 18, 20, 22, and 24) form a cavity into which the phycocyanobilin chromophore can be modeled. This location of the chromophore is supported by mutations at the interface between the subunits and within the cavity. The structure of a structurally related, isomerizing lyase, PecE/F, that converts phycocyanobilin into phycoviolobilin, was modeled using the CpcE/F structure as template. A H87C88 motif critical for the isomerase activity of PecE/F is located at the loop between h20 and h21, supporting the proposal that the nucleophilic addition of Cys-88 to C10 of phycocyanobilin induces the isomerization of phycocyanobilin into phycoviolobilin. Also, the structure of NblB, involved in phycobilisome degradation could be modeled using CpcE as template. Combined with CpcF, NblB shows a low chromophore-detaching activity. PMID- 29180422 TI - Storm, rogue wave, or tsunami origin for megaclast deposits in western Ireland and North Island, New Zealand? AB - The origins of boulderite deposits are investigated with reference to the present day foreshore of Annagh Head, NW Ireland, and the Lower Miocene Matheson Formation, New Zealand, to resolve disputes on their origin and to contrast and compare the deposits of tsunamis and storms. Field data indicate that the Matheson Formation, which contains boulders in excess of 140 tonnes, was produced by a 12- to 13-m-high tsunami with a period in the order of 1 h. The origin of the boulders at Annagh Head, which exceed 50 tonnes, is disputed. We combine oceanographic, historical, and field data to argue that this is a cliff-top storm deposit (CTSD). A numerical model for CTSDs is developed which indicates that boulder shape in addition to density and dimensions should be taken into account when applying hydrodynamic equations to such deposits. The model also predicts that the NE Atlantic storms are capable of producing boulderites that, when size alone is considered, cannot be distinguished from tsunamites. We review the characteristics that identify the origins of these two deposits. PMID- 29180421 TI - Metal transporter Slc39a10 regulates susceptibility to inflammatory stimuli by controlling macrophage survival. AB - Zn plays a key role in controlling macrophage function during an inflammatory event. Cellular Zn homeostasis is regulated by two families of metal transporters, the SLC39A family of importers and the SLC30A family of exporters; however, the precise role of these transporters in maintaining macrophage function is poorly understood. Using macrophage-specific Slc39a10-knockout (Slc39a10fl/fl;LysM-Cre+ ) mice, we found that Slc39a10 plays an essential role in macrophage survival by mediating Zn homeostasis in response to LPS stimulation. Compared with Slc39a10fl/fl mice, Slc39a10fl/fl;LysM-Cre+ mice had significantly lower mortality following LPS stimulation as well as reduced liver damage and lower levels of circulating inflammatory cytokines. Moreover, reduced intracellular Zn concentration in Slc39a10fl/fl;LysM-Cre+ macrophages led to the stabilization of p53, which increased apoptosis upon LPS stimulation. Concomitant knockout of p53 largely rescued the phenotype of Slc39a10fl/fl;LysM-Cre+ mice. Finally, the phenotype in Slc39a10fl/fl;LysM-Cre+ mice was mimicked in wild-type mice using the Zn chelator TPEN and was reversed with Zn supplementation. Taken together, these results suggest that Slc39a10 plays a role in promoting the survival of macrophages through a Zn/p53-dependent axis in response to inflammatory stimuli. PMID- 29180424 TI - Causes of ice age intensification across the Mid-Pleistocene Transition. AB - During the Mid-Pleistocene Transition (MPT; 1,200-800 kya), Earth's orbitally paced ice age cycles intensified, lengthened from ~40,000 (~40 ky) to ~100 ky, and became distinctly asymmetrical. Testing hypotheses that implicate changing atmospheric CO2 levels as a driver of the MPT has proven difficult with available observations. Here, we use orbitally resolved, boron isotope CO2 data to show that the glacial to interglacial CO2 difference increased from ~43 to ~75 MUatm across the MPT, mainly because of lower glacial CO2 levels. Through carbon cycle modeling, we attribute this decline primarily to the initiation of substantive dust-borne iron fertilization of the Southern Ocean during peak glacial stages. We also observe a twofold steepening of the relationship between sea level and CO2-related climate forcing that is suggestive of a change in the dynamics that govern ice sheet stability, such as that expected from the removal of subglacial regolith or interhemispheric ice sheet phase-locking. We argue that neither ice sheet dynamics nor CO2 change in isolation can explain the MPT. Instead, we infer that the MPT was initiated by a change in ice sheet dynamics and that longer and deeper post-MPT ice ages were sustained by carbon cycle feedbacks related to dust fertilization of the Southern Ocean as a consequence of larger ice sheets. PMID- 29180423 TI - Prenatal stress accelerates offspring growth to compensate for reduced maternal investment across mammals. AB - Across mammals, prenatal maternal stress (PREMS) affects many aspects of offspring development, including offspring growth. However, how PREMS translates to offspring growth is inconsistent, even within species. To explain the full range of reported effects of prenatal adversity on offspring growth, we propose an integrative hypothesis: developmental constraints and a counteracting adaptive growth plasticity work in opposition to drive PREMS effects on growth. Mothers experiencing adversity reduce maternal investment leading to stunted growth (developmental constraints). Concomitantly, the pace of offspring life history is recalibrated to partly compensate for these developmental constraints (adaptive growth plasticity). Moreover, the relative importance of each process changes across ontogeny with increasing offspring independence. Thus, offspring exposed to PREMS may grow at the same rate as controls during gestation and lactation, but faster after weaning when direct maternal investment has ceased. We tested these predictions with a comparative analysis on the outcomes of 719 studies across 21 mammal species. First, the observed growth changes in response to PREMS varied across offspring developmental periods as predicted. We argue that the observed growth acceleration after weaning is not "catch-up growth," because offspring that were small for age grew slower. Second, only PREMS exposure early during gestation produced adaptive growth plasticity. Our results suggest that PREMS effects benefit the mother's future reproduction and at the same time accelerate offspring growth and possibly maturation and reproductive rate. In this sense, PREMS effects on offspring growth allow mother and offspring to make the best of a bad start. PMID- 29180425 TI - Interaction of intramembrane metalloprotease SpoIVFB with substrate Pro-sigmaK. AB - Intramembrane proteases (IPs) cleave membrane-associated substrates in nearly all organisms and regulate diverse processes. A better understanding of how these enzymes interact with their substrates is necessary for rational design of IP modulators. We show that interaction of Bacillus subtilis IP SpoIVFB with its substrate Pro-sigmaK depends on particular residues in the interdomain linker of SpoIVFB. The linker plus either the N-terminal membrane domain or the C-terminal cystathione-beta-synthase (CBS) domain of SpoIVFB was sufficient for the interaction but not for cleavage of Pro-sigmaK Chemical cross-linking and mass spectrometry of purified, inactive SpoIVFB-Pro-sigmaK complex indicated residues of the two proteins in proximity. A structural model of the complex was built via partial homology and by using constraints based on cross-linking data. In the model, the Proregion of Pro-sigmaK loops into the membrane domain of SpoIVFB, and the rest of Pro-sigmaK interacts extensively with the linker and the CBS domain of SpoIVFB. The extensive interaction is proposed to allow coordination between ATP binding by the CBS domain and Pro-sigmaK cleavage by the membrane domain.

AB - POT transporters represent an evolutionarily well-conserved family of proton coupled transport systems in biology. An unusual feature of the family is their ability to couple the transport of chemically diverse ligands to an inwardly directed proton electrochemical gradient. For example, in mammals, fungi, and bacteria they are predominantly peptide transporters, whereas in plants the family has diverged to recognize nitrate, plant defense compounds, and hormones. Although recent structural and biochemical studies have identified conserved sites of proton binding, the mechanism through which transport is coupled to proton movement remains enigmatic. Here we show that different POT transporters operate through distinct proton-coupled mechanisms through changes in the extracellular gate. A high-resolution crystal structure reveals the presence of ordered water molecules within the peptide binding site. Multiscale molecular dynamics simulations confirm proton transport occurs through these waters via Grotthuss shuttling and reveal that proton binding to the extracellular side of the transporter facilitates a reorientation from an inward- to outward-facing state. Together these results demonstrate that within the POT family multiple mechanisms of proton coupling have likely evolved in conjunction with variation of the extracellular gate. PMID- 29180428 TI - Development of self-protective biases in response to social evaluative feedback. AB - Adolescence is a developmental period marked by heightened attunement to social evaluation. While adults have been shown to enact self-protective processes to buffer their self-views from evaluative threats like peer rejection, it is unclear whether adolescents avail themselves of the same defenses. The present study examines how social evaluation shapes views of the self and others differently across development. N = 107 participants ages 10-23 completed a reciprocal social evaluation task that involved predicting and receiving peer acceptance and rejection feedback, along with assessments of self-views and likability ratings of peers. Here, we show that, despite equivalent experiences of social evaluation, adolescents internalized peer rejection, experiencing a feedback-induced drop in self-views, whereas adults externalized peer rejection, reporting a task-induced boost in self-views and deprecating the peers who rejected them. The results identify codeveloping processes underlying why peer rejection may lead to more dramatic alterations in self-views during adolescence than other phases of the lifespan. PMID- 29180427 TI - AP-4 mediates export of ATG9A from the trans-Golgi network to promote autophagosome formation. AB - AP-4 is a member of the heterotetrameric adaptor protein (AP) complex family involved in protein sorting in the endomembrane system of eukaryotic cells. Interest in AP-4 has recently risen with the discovery that mutations in any of its four subunits cause a form of hereditary spastic paraplegia (HSP) with intellectual disability. The critical sorting events mediated by AP-4 and the pathogenesis of AP-4 deficiency, however, remain poorly understood. Here we report the identification of ATG9A, the only multispanning membrane component of the core autophagy machinery, as a specific AP-4 cargo. AP-4 promotes signal mediated export of ATG9A from the trans-Golgi network to the peripheral cytoplasm, contributing to lipidation of the autophagy protein LC3B and maturation of preautophagosomal structures. These findings implicate AP-4 as a regulator of autophagy and altered autophagy as a possible defect in AP-4 deficient HSP. PMID- 29180429 TI - Kinematics of flagellar swimming in Euglena gracilis: Helical trajectories and flagellar shapes. AB - The flagellar swimming of euglenids, which are propelled by a single anterior flagellum, is characterized by a generalized helical motion. The 3D nature of this swimming motion, which lacks some of the symmetries enjoyed by more common model systems, and the complex flagellar beating shapes that power it make its quantitative description challenging. In this work, we provide a quantitative, 3D, highly resolved reconstruction of the swimming trajectories and flagellar shapes of specimens of Euglena gracilis We achieved this task by using high-speed 2D image recordings taken with a conventional inverted microscope combined with a precise characterization of the helical motion of the cell body to lift the 2D data to 3D trajectories. The propulsion mechanism is discussed. Our results constitute a basis for future biophysical research on a relatively unexplored type of eukaryotic flagellar movement. PMID- 29180430 TI - Def1 interacts with TFIIH and modulates RNA polymerase II transcription. AB - The DNA damage response is an essential process for the survival of living cells. In a subset of stress-responsive genes in humans, Elongin controls transcription in response to multiple stimuli, such as DNA damage, oxidative stress, and heat shock. Yeast Elongin (Ela1-Elc1), along with Def1, is known to facilitate ubiquitylation and degradation of RNA polymerase II (pol II) in response to multiple stimuli, yet transcription activity has not been examined. We have found that Def1 copurifies from yeast whole-cell extract with TFIIH, the largest general transcription factor required for transcription initiation and nucleotide excision repair. The addition of recombinant Def1 and Ela1-Elc1 enhanced transcription initiation in an in vitro reconstituted system including pol II, the general transcription factors, and TFIIS. Def1 also enhanced transcription restart from TFIIS-induced cleavage in a pol II transcribing complex. In the Deltadef1 strain, heat shock genes were misregulated, indicating that Def1 is required for induction of some stress-responsive genes in yeast. Taken together, our results extend the understanding of the molecular mechanism of transcription regulation on cellular stress and reveal functional similarities to the mammalian system. PMID- 29180431 TI - Amorphous MoS3 as the sulfur-equivalent cathode material for room-temperature Li S and Na-S batteries. AB - Many problems associated with Li-S and Na-S batteries essentially root in the generation of their soluble polysulfide intermediates. While conventional wisdom mainly focuses on trapping polysulfides at the cathode using various functional materials, few strategies are available at present to fully resolve or circumvent this long-standing issue. In this study, we propose the concept of sulfur equivalent cathode materials, and demonstrate the great potential of amorphous MoS3 as such a material for room-temperature Li-S and Na-S batteries. In Li-S batteries, MoS3 exhibits sulfur-like behavior with large reversible specific capacity, excellent cycle life, and the possibility to achieve high areal capacity. Most remarkably, it is also fully cyclable in the carbonate electrolyte under a relatively high temperature of 55 degrees C. MoS3 can also be used as the cathode material of even more challenging Na-S batteries to enable decent capacity and good cycle life. Operando X-ray absorption spectroscopy (XAS) experiments are carried out to track the structural evolution of MoS3 It largely preserves its chain-like structure during repetitive battery cycling without generating any free polysulfide intermediates. PMID- 29180432 TI - Phosphorylation of CENP-C by Aurora B facilitates kinetochore attachment error correction in mitosis. AB - Kinetochores are superprotein complexes that orchestrate chromosome segregation via a dynamic interaction with spindle microtubules. A physical connection between CENP-C and the Mis12-Ndc80-Knl1 (KMN) protein network is an important pathway that is used to assemble kinetochores on CENP-A nucleosomes. Multiple outer kinetochore components are phosphorylated by Aurora B kinase to activate the spindle assembly checkpoint (SAC) and to ensure accurate chromosome segregation. However, it is unknown whether Aurora B can phosphorylate inner kinetochore components to facilitate proper mitotic chromosome segregation. Here, we reported the structure of the fission yeast Schizosaccharomyces pombe Mis12 Nnf1 complex and showed that N-terminal residues 26-50 in Cnp3 (the CENP-C homolog of S. pombe) are responsible for interacting with the Mis12 complex. Interestingly, Thr28 of Cnp3 is a substrate of Ark1 (the Aurora B homolog of S. pombe), and phosphorylation impairs the interaction between the Cnp3 and Mis12 complex. The expression of a phosphorylation-mimicking Cnp3 mutant results in defective chromosome segregation due to improper kinetochore assembly. These results establish a previously uncharacterized regulatory mechanism involved in CENP-C-Mis12-facilitated kinetochore attachment error correction to ensure accurate chromosome segregation during mitosis. PMID- 29180433 TI - A STAT3-dependent transcriptional circuitry inhibits cytotoxic gene expression in T cells. AB - CD8+ T cells are preprogrammed for cytotoxic differentiation in the thymus as they acquire expression of the transcription factor Runx3. However, a subset of effector CD8+ T cells (Tc17) produce IL-17 and fail to express cytotoxic genes. Here, we show that the transcription factors directing IL-17 production, STAT3 and RORgammat, inhibit cytotoxicity despite persistent Runx3 expression. Cytotoxic gene repression did not require the transcription factor Thpok, which in CD4+ T cells restrains Runx3 functions and cytotoxicity; and STAT3 restrained cytotoxic gene expression in CD8+ T cells responding to viral infection in vivo. STAT3-induced RORgammat represses cytotoxic genes by inhibiting the functions but not the expression of the "cytotoxic" transcription factors T-bet and Eomesodermin. Thus, the transcriptional circuitry directing IL-17 expression inhibits cytotoxic functions. However, by allowing expression of activators of the cytotoxic program, this inhibitory mechanism contributes to the instability of IL-17-producing T cells. PMID- 29180434 TI - Synaptic homeostasis requires the membrane-proximal carboxy tail of GluA2. AB - Bidirectional scaling of synaptic transmission, expressed as a compensatory change in quantal size following chronic activity perturbation, is a critical effector mechanism underlying homeostatic plasticity in the brain. An emerging model posits that the GluA2 AMPA receptor (AMPAR) subunit may be important for the bidirectional scaling of excitatory transmission; however, whether this subunit plays an obligatory role in synaptic scaling, and the identity of the precise domain(s) involved, remain controversial. We set out to determine the specific AMPAR subunit required for scaling up in CA1 hippocampal pyramidal neurons, and found that the GluA2 subunit is both necessary and sufficient. In addition, our results point to a critical role for a single amino acid within the membrane-proximal region of the GluA2 cytoplasmic tail, and suggest a distinct model for the regulation of AMPAR trafficking in synaptic homeostasis. PMID- 29180435 TI - Bicaudal D2 facilitates the cytoplasmic trafficking and nuclear import of HIV-1 genomes during infection. AB - Numerous viruses, including HIV-1, exploit the microtubule network to traffic toward the nucleus during infection. Although numerous studies have observed a role for the minus-end microtubule motor dynein in HIV-1 infection, the mechanism by which the viral core containing the viral genome associates with dynein and induces its perinuclear trafficking has remained unclear. Here, we report that the dynein adapter protein bicaudal D2 (BICD2) is able to interact with HIV-1 viral cores in target cells. We also observe that BICD2 can bind in vitro assembled capsid tubes through its CC3 domain. We observe that BICD2 facilitates infection by promoting the trafficking of viral cores to the nucleus, thereby promoting nuclear entry of the viral genome and infection. Finally, we observe that depletion of BICD2 in the monocytic cell line THP-1 results in an induction of IFN-stimulated genes in these cells. Collectively, these results identify a microtubule adapter protein critical for trafficking of HIV-1 in the cytoplasm of target cells and evasion of innate sensing mechanisms in macrophages. PMID- 29180436 TI - Broad detection of bacterial type III secretion system and flagellin proteins by the human NAIP/NLRC4 inflammasome. AB - Inflammasomes are cytosolic multiprotein complexes that initiate host defense against bacterial pathogens by activating caspase-1-dependent cytokine secretion and cell death. In mice, specific nucleotide-binding domain, leucine-rich repeat containing family, apoptosis inhibitory proteins (NAIPs) activate the nucleotide binding domain, leucine-rich repeat-containing family, CARD domain-containing protein 4 (NLRC4) inflammasome upon sensing components of the type III secretion system (T3SS) and flagellar apparatus. NAIP1 recognizes the T3SS needle protein, NAIP2 recognizes the T3SS inner rod protein, and NAIP5 and NAIP6 recognize flagellin. In contrast, humans encode a single functional NAIP, raising the question of whether human NAIP senses one or multiple bacterial ligands. Previous studies found that human NAIP detects both flagellin and the T3SS needle protein and suggested that the ability to detect both ligands was achieved by multiple isoforms encoded by the single human NAIP gene. Here, we show that human NAIP also senses the Salmonella Typhimurium T3SS inner rod protein PrgJ and that T3SS inner rod proteins from multiple bacterial species are also detected. Furthermore, we show that a single human NAIP isoform is capable of sensing the T3SS inner rod, needle, and flagellin. Our findings indicate that, in contrast to murine NAIPs, promiscuous recognition of multiple bacterial ligands is conferred by a single human NAIP. PMID- 29180437 TI - Solving visual correspondence between the two eyes via domain-based population encoding in nonhuman primates. AB - Stereoscopic vision depends on correct matching of corresponding features between the two eyes. It is unclear where the brain solves this binocular correspondence problem. Although our visual system is able to make correct global matches, there are many possible false matches between any two images. Here, we use optical imaging data of binocular disparity response in the visual cortex of awake and anesthetized monkeys to demonstrate that the second visual cortical area (V2) is the first cortical stage that correctly discards false matches and robustly encodes correct matches. Our findings indicate that a key transformation for achieving depth perception lies in early stages of extrastriate visual cortex and is achieved by population coding. PMID- 29180439 TI - Goodhart's law: when waiting times became a target, they stopped being a good measure. PMID- 29180438 TI - Protective effects of agonists of growth hormone-releasing hormone (GHRH) in early experimental diabetic retinopathy. AB - The potential therapeutic effects of agonistic analogs of growth hormone releasing hormone (GHRH) and their mechanism of action were investigated in diabetic retinopathy (DR). Streptozotocin-induced diabetic rats (STZ-rats) were treated with 15 MUg/kg GHRH agonist, MR-409, or GHRH antagonist, MIA-602. At the end of treatment, morphological and biochemical analyses assessed the effects of these compounds on retinal neurovascular injury induced by hyperglycemia. The expression levels of GHRH and its receptor (GHRH-R) measured by qPCR and Western blotting were significantly down-regulated in retinas of STZ-rats and in human diabetic retinas (postmortem) compared with their respective controls. Treatment of STZ-rats with the GHRH agonist, MR-409, prevented retinal morphological alteration induced by hyperglycemia, particularly preserving survival of retinal ganglion cells. The reverse, using the GHRH antagonist, MIA-602, resulted in worsening of retinal morphology and a significant alteration of the outer retinal layer. Explaining these results, we have found that MR-409 exerted antioxidant and anti-inflammatory effects in retinas of the treated rats, as shown by up regulation of NRF-2-dependent gene expression and down-regulation of proinflammatory cytokines and adhesion molecules. MR-409 also significantly down regulated the expression of vascular endothelial growth factor while increasing that of pigment epithelium-derived factor in diabetic retinas. These effects correlated with decreased vascular permeability. In summary, our findings suggest a neurovascular protective effect of GHRH analogs during the early stage of diabetic retinopathy through their antioxidant and anti-inflammatory properties. PMID- 29180440 TI - TIMP3 is a CLOCK-dependent diurnal gene that inhibits the expression of UVB induced inflammatory cytokines in human keratinocytes. AB - As the outermost physical barrier of an organism, the skin is diurnally exposed to UV radiation (UVR). Recent studies have revealed that the skin exhibits a circadian rhythm in various functions, and this oscillation is disturbed and reset via a strong environmental cue, the UVR. However, a molecular link between circadian perturbation by UVR and UVR-induced cellular responses has not been investigated. We identified tissue inhibitor of metalloproteinase ( TIMP)- 3 as a novel circadian locomotor output cycles kaput (CLOCK)-dependent diurnal gene by using a CLOCK-knockdown strategy in human keratinocytes. Among dozens of identified transcripts down-regulated by CLOCK knockdown, TIMP3 displayed a rhythmic expression in a CLOCK-dependent manner, in which the expression of matrix metalloproteinase (MMP)-1 and inflammatory cytokines, such as TNF-alpha, chemokine (C-X-C motif) ligand (CXCL)-1, and IL-8, were inversely regulated. Upon UVB exposure, the expression of CLOCK and TIMP3 was down-regulated, which led to an up-regulation of secretion of MMP1 and TNF-alpha proteins and in the transcription of CXCL1 and IL-8 via CCAAT-enhancer binding protein (C/EBP)-alpha. UVB-induced TNF-alpha secretion increased further or decreased by knockdown or overexpression of TIMP3, respectively, as well as by CLOCK. As a novel CLOCK dependent diurnal gene, TIMP3 inhibits the expression of inflammatory cytokines that are up-regulated by UV irradiation in human keratinocytes. Thus, our work suggests a molecular link between circadian perturbation by UVR and UVR-induced inflammation.-Park, S., Kim, K., Bae, I.-H., Lee, S. H., Jung, J., Lee, T. R., Cho, E.-G. TIMP3 is a CLOCK-dependent diurnal gene that inhibits the expression of UVB-induced inflammatory cytokines in human keratinocytes. PMID- 29180441 TI - Neural deletion of Sh2b1 results in brain growth retardation and reactive aggression. AB - Psychiatric disorders are associated with aberrant brain development and/or aggressive behavior and are influenced by genetic factors; however, genes that affect brain aggression circuits remain elusive. Here, we show that neuronal Src homology-2 (SH2)B adaptor protein-1 ( Sh2b1) is indispensable for both brain growth and protection against aggression. Global and brain-specific deletion of Sh2b1 decreased brain weight and increased aggressive behavior. Global and brain specific Sh2b1 knockout (KO) mice exhibited fatal, intermale aggression. In a resident-intruder paradigm, latency to attack was markedly reduced, whereas the number and the duration of attacks was significantly increased in global and brain-specific Sh2b1 KO mice compared with wild-type littermates. Consistently, core aggression circuits were activated to a higher level in global and brain specific Sh2b1 KO males, based on c-fos immunoreactivity in the amygdala and periaqueductal gray. Brain-specific restoration of Sh2b1 normalized brain size and reversed pathologic aggression and aberrant activation of core aggression circuits in Sh2b1 KO males. SH2B1 mutations in humans were linked to aberrant brain development and behavior. At the molecular level, Sh2b1 enhanced neurotrophin-stimulated neuronal differentiation and protected against oxidative stress-induced neuronal death. Our data suggest that neuronal Sh2b1 promotes brain development and the integrity of core aggression circuits, likely through enhancing neurotrophin signaling.-Jiang, L., Su, H., Keogh, J. M., Chen, Z., Henning, E., Wilkinson, P., Goodyer, I., Farooqi, I. S., Rui, L. Neural deletion of Sh2b1 results in brain growth retardation and reactive aggression. PMID- 29180442 TI - KCa2 channel localization and regulation in the axon initial segment. AB - Small conductance calcium-activated potassium (KCa2) channels are expressed throughout the CNS and play a critical role in synaptic and neuronal excitability. KCa2 channels have a somatodendritic distribution with their highest expression in distal dendrites. It is unclear whether KCa2 channels are specifically present on the axon initial segment (AIS), the site at which action potentials are initiated in neurons. Through a powerful combination of toxin pharmacology, single-molecule atomic force microscopy, and dual-color fluorescence microscopy, we report here that KCa2 channels-predominantly the KCa2.3 subtype-are indeed present on the AIS. We also report that cAMP-PKA controls the axonal KCa2 channel surface expression. Surprisingly, and in contrast to KCa2 channels that were observed in the soma and dendrites, the inhibition of cAMP-PKA increased the surface expression of KCa2 channels without promoting nanoclustering. Lastly, we found that axonal KCa2 channels seem to undergo endocytosis in a dynamin-independent manner, unlike KCa2 channels in the soma and dendrites. Together, these novel results demonstrate that the distribution and membrane recycling of KCa2 channels differs among various neuronal subcompartments.-Abiraman, K., Tzingounis, A. V., Lykotrafitis, G. KCa2 channel localization and regulation in the axon initial segment. PMID- 29180443 TI - Genomic and lipidomic analyses differentiate the compensatory roles of two COX isoforms during systemic inflammation in mice. AB - Both cyclooxygenase (COX)-1 and COX-2, encoded by Ptgs1 and Ptgs2, function coordinately during inflammation. But the relative contributions and compensations of COX-1 and COX-2 to inflammatory responses remain unanswered. We used three engineered mouse lines where the Ptgs1 and Ptgs2 genes substitute for one another to discriminate the distinct roles and interchangeability of COX isoforms during systemic inflammation. In macrophages, kidneys, and lungs, "flipped" Ptgs genes generate a "reversed" COX expression pattern, where the knock-in COX-2 is expressed constitutively and the knock-in COX-1 is lipopolysaccharide inducible. A panel of eicosanoids detected in serum and kidney demonstrates that prostaglandin (PG) biosynthesis requires native COX-1 and cannot be rescued by the knock-in COX-2. Our data further reveal preferential compensation of COX isoforms for prostanoid production in macrophages and throughout the body, as reflected by urinary PG metabolites. NanoString analysis indicates that inflammatory networks can be maintained by isoform substitution in inflamed macrophages. However, COX-1>COX-2 macrophages show reduced activation of inflammatory signaling pathways, indicating that COX-1 may be replaced by COX-2 within this complex milieu, but not vice versa. Collectively, each COX isoform plays a distinct role subject to subcellular environment and tissue/cell-specific conditions, leading to subtle compensatory differences during systemic inflammation. PMID- 29180444 TI - PCSK9 deficiency reduces atherosclerosis, apolipoprotein B secretion, and endothelial dysfunction. AB - Proprotein convertase subtilisin/kexin type 9 (PCSK9) interacts directly with cytoplasmic apoB and prevents its degradation via the autophagosome/lysosome pathway. This process affects VLDL and LDL production and influences atherogenesis. Here, we investigated the molecular machinery by which PCSK9 modulates autophagy and affects atherogenesis. We backcrossed Pcsk9-/- mice with atherosclerosis-prone Ldlr-/-Apobec1-/- (LDb) mice to generate Ldlr-/-Apobec1-/ Pcsk9-/- (LTp) mice. Deletion of PCSK9 resulted in decreased hepatic apoB secretion, increased autophagic flux, and decreased plasma levels of IDL and LDL particles. The LDLs from LTp mice (LTp-LDLs) were less atherogenic and contained less cholesteryl ester and phospholipids than LDb-LDLs. Moreover LTp-LDLs induced lower endothelial expression of the genes encoding TLR2, Lox-1, ICAM-1, CCL2, CCL7, IL-6, IL-1beta, Beclin-1, p62, and TRAF6 Collectively, these effects were associated with substantially less atherosclerosis development (>4-fold) in LTp mice. The absence of PCSK9 in LDb mice results in decreased lipid and apoB levels, fewer atherogenic LDLs, and marked reduction of atherosclerosis. The effect on atherogenesis may be mediated in part by the effects of modified LDLs on endothelial cell receptors and proinflammatory and autophagy molecules. These findings suggest that there may be clinical benefits of PCSK9 inhibition due to mechanisms unrelated to increased LDL receptor activity. PMID- 29180445 TI - Flipping the cyclooxygenase (Ptgs) genes reveals isoform-specific compensatory functions. AB - Two prostaglandin (PG) H synthases encoded by Ptgs genes, colloquially known as cyclooxygenase (COX)-1 and COX-2, catalyze the formation of PG endoperoxide H2, the precursor of the major prostanoids. To address the functional interchangeability of these two isoforms and their distinct roles, we have generated COX-2>COX-1 mice whereby Ptgs2 is knocked in to the Ptgs1 locus. We then "flipped" Ptgs genes to successfully create the Reversa mouse strain, where knock-in COX-2 is expressed constitutively and knock-in COX-1 is lipopolysaccharide (LPS) inducible. In macrophages, flipping the two Ptgs genes has no obvious impact on COX protein subcellular localization. COX-1 was shown to compensate for PG synthesis at high concentrations of substrate, whereas elevated LPS-induced PG production was only observed for cells expressing endogenous COX 2. Differential tissue-specific patterns of expression of the knock-in proteins were evident. Thus, platelets from COX-2>COX-1 and Reversa mice failed to express knock-in COX-2 and, therefore, thromboxane (Tx) production in vitro and urinary Tx metabolite formation in COX-2>COX-1 and Reversa mice in vivo were substantially decreased relative to WT and COX-1>COX-2 mice. Manipulation of COXs revealed isoform-specific compensatory functions and variable degrees of interchangeability for PG biosynthesis in cells/tissues. PMID- 29180446 TI - Quantitative ligand and receptor binding studies reveal the mechanism of interleukin-36 (IL-36) pathway activation. AB - IL-36 cytokines signal through the IL-36 receptor (IL-36R) and a shared subunit, IL-1RAcP (IL-1 receptor accessory protein). The activation mechanism for the IL 36 pathway is proposed to be similar to that of IL-1 in that an IL-36R agonist (IL-36alpha, IL-36beta, or IL-36gamma) forms a binary complex with IL-36R, which then recruits IL-1RAcP. Recent studies have shown that IL-36R interacts with IL 1RAcP even in the absence of an agonist. To elucidate the IL-36 activation mechanism, we considered all possible binding events for IL-36 ligands/receptors and examined these events in direct binding assays. Our results indicated that the agonists bind the IL-36R extracellular domain with micromolar affinity but do not detectably bind IL-1RAcP. Using surface plasmon resonance (SPR), we found that IL-1RAcP also does not bind IL-36R when no agonist is present. In the presence of IL-36alpha, however, IL-1RAcP bound IL-36R strongly. These results suggested that the main pathway to the IL-36R.IL-36alpha.IL-1RAcP ternary complex is through the IL-36R.IL-36alpha binary complex, which recruits IL-1RAcP. We could not measure the binding affinity of IL-36R to IL-1RAcP directly, so we engineered a fragment crystallizable-linked construct to induce IL-36R.IL-1RAcP heterodimerization and predicted the binding affinity during a complete thermodynamic cycle to be 74 MUm The SPR analysis also indicated that the IL-36R antagonist IL-36Ra binds IL-36R with higher affinity and a much slower off rate than the IL-36R agonists, shedding light on IL-36 pathway inhibition. Our results reveal the landscape of IL-36 ligand and receptor interactions, improving our understanding of IL-36 pathway activation and inhibition. PMID- 29180447 TI - A variant of death-receptor 3 associated with rheumatoid arthritis interferes with apoptosis-induction of T cell. AB - Rheumatoid arthritis (RA) is a chronic polyarthritis of unknown etiology. To unravel the molecular mechanisms in RA, we performed targeted DNA sequencing analysis of patients with RA. This analysis identified a variant of the death receptor 3 (DR3) gene, a member of the family of apoptosis-inducing Fas genes, which contains four single-nucleotide polymorphisms (SNPs) and a 14-nucleotide deletion within exon 5 and intron 5. We found that the deletion causes the binding of splicing regulatory proteins to DR3 pre-mRNA intron 5, resulting in a portion of intron 5 becoming part of the coding sequence, thereby generating a premature stop codon. We also found that this truncated DR3 protein product lacks the death domain and forms a heterotrimer complex with wildtype DR3 that dominant negatively inhibits ligand-induced apoptosis in lymphocytes. Myelocytes from transgenic mice expressing the human DR3 variant produced soluble truncated DR3, forming a complex with TNF-like ligand 1A (TL1A), which inhibited apoptosis induction. In summary, our results reveal that a DR3 splice variant that interferes with ligand-induced T cell responses and apoptosis may contribute to RA pathogenesis. PMID- 29180448 TI - A neutralizing antibody that blocks delivery of the enzymatic cargo of Clostridium difficile toxin TcdB into host cells. AB - Clostridium difficile infection is the leading cause of hospital-acquired diarrhea and is mediated by the actions of two toxins, TcdA and TcdB. The toxins perturb host cell function through a multistep process of receptor binding, endocytosis, low pH-induced pore formation, and the translocation and delivery of an N-terminal glucosyltransferase domain that inactivates host GTPases. Infection studies with isogenic strains having defined toxin deletions have established TcdB as an important target for therapeutic development. Monoclonal antibodies that neutralize TcdB function have been shown to protect against C. difficile infection in animal models and reduce recurrence in humans. Here, we report the mechanism of TcdB neutralization by PA41, a humanized monoclonal antibody capable of neutralizing TcdB from a diverse array of C. difficile strains. Through a combination of structural, biochemical, and cell functional studies, involving X ray crystallography and EM, we show that PA41 recognizes a single, highly conserved epitope on the TcdB glucosyltransferase domain and blocks productive translocation and delivery of the enzymatic cargo into the host cell. Our study reveals a unique mechanism of C. difficile toxin neutralization by a monoclonal antibody, which involves targeting a process that is conserved across the large clostridial glucosylating toxins. The PA41 antibody described here provides a valuable tool for dissecting the mechanism of toxin pore formation and translocation across the endosomal membrane. PMID- 29180449 TI - Ligand-specific conformational transitions and intracellular transport are required for atypical chemokine receptor 3-mediated chemokine scavenging. AB - The atypical chemokine receptor ACKR3 contributes to chemotaxis by binding, internalizing, and degrading the chemokines CXCL11 and CXCL12 to shape and terminate chemotactic gradients during development and immune responses. Although unable to trigger G protein activation, both ligands activate G protein independent ACKR3 responses and prompt arrestin recruitment. This offers a model to specifically study ligand-specific receptor conformations leading to G protein independent signaling and to functional parameters such as receptor transport and chemokine degradation. We here show chemokine specificity in arrestin recruitment, by different effects of single amino acid substitutions in ACKR3 on arrestin in response to CXCL12 or CXCL11. Chemokine specificity in receptor transport was also observed, as CXCL11 induced faster receptor internalization, slower recycling, and longer intracellular sojourn of ACKR3 than CXCL12. Internalization and recycling rates of the ACKR3 R1423.50A substitution in response to each chemokine were similar; however, ACKR3 R1423.50A degraded only CXCL12 and not CXCL11. This suggests that ligand-specific intracellular receptor transport is required for chemokine degradation. Remarkably, the failure of ACKR3 R1423.50A to degrade CXCL11 was not caused by the lack of arrestin recruitment; rather, arrestin was entirely dispensable for scavenging of either chemokine. This suggests the involvement of another, yet unidentified, ACKR3 effector in scavenging. In summary, our study correlates ACKR3 ligand-specific conformational transitions with chemokine-dependent receptor transport dynamics and points toward unexpected ligand specificity in the mechanisms of chemokine degradation. PMID- 29180450 TI - Knockout of mitochondrial voltage-dependent anion channel type 3 increases reactive oxygen species (ROS) levels and alters renal sodium transport. AB - It has been suggested that voltage-dependent anion channels (VDACs) control the release of superoxide from mitochondria. We have previously shown that reactive oxygen species (ROS) such as superoxide (O2) and hydrogen peroxide (H2O2) stimulate epithelial sodium channels (ENaCs) in sodium-transporting epithelial tissue, including cortical collecting duct (CCD) principal cells. Therefore, we hypothesized that VDACs could regulate ENaC by modulating cytosolic ROS levels. Herein, we find that VDAC3-knockout(KO) mice can maintain normal salt and water balance on low-salt and high-salt diets. However, on a high-salt diet for 2 weeks, VDAC3-KO mice had significantly higher systolic blood pressure than wildtype mice. Consistent with this observation, after a high-salt diet for 2 weeks, ENaC activity in VDAC3-KO mice was significantly higher than wildtype mice. EM analysis disclosed a significant morphological change of mitochondria in the CCD cells of VDAC3-KO mice compared with wildtype mice, which may have been caused by mitochondrial superoxide overload. Of note, compared with wildtype animals, ROS levels in VDAC3-KO animals fed a normal or high-salt diet were consistently and significantly increased in renal tubules. Both the ROS scavenger 1-oxyl-2,2,6,6-tetramethyl-4-hydroxypiperidine (TEMPOL) and the mitochondrial ROS scavenger (2-(2,2,6,6-tetramethylpiperidin-1-oxyl-4-ylamino)-2 oxoethyl)triphenylphosphonium chloride (mito-TEMPO) could reverse the effect of high-salt on ENaC activity and systolic blood pressure in the VDAC3-KO mice. Mito TEMPO partially correct the morphological changes in VDAC3-KO mice. Our results suggest that knocking out mitochondrial VDAC3 increases ROS, alters renal sodium transport, and leads to hypertension.

AB - L-type voltage-gated CaV1.2 calcium channels (CaV1.2) are key regulators of neuronal excitability, synaptic plasticity, and excitation-transcription coupling. Surface-exposed CaV1.2 distributes in clusters along the dendrites of hippocampal neurons. A permanent exchange between stably clustered and laterally diffusive extra-clustered channels maintains steady-state levels of CaV1.2 at dendritic signaling domains. A dynamic equilibrium between anchored and diffusive receptors is a common feature among ion channels and is crucial to modulate signaling transduction. Despite the importance of this fine regulatory system, the molecular mechanisms underlying the surface dynamics of CaV1.2 are completely unexplored. Here, we examined the dynamic states of CaV1.2 depending on phosphorylation on Ser-1700 and Ser-1928 at the channel C terminus. Phosphorylation at these sites is strongly involved in CaV1.2-mediated nuclear factor of activated T cells (NFAT) signaling, long-term potentiation, and responsiveness to adrenergic stimulation. We engineered CaV1.2 constructs mimicking phosphorylation at Ser-1700 and Ser-1928 and analyzed their behavior at the membrane by immunolabeling protocols, fluorescence recovery after photobleaching, and single particle tracking. We found that the phosphomimetic S1928E variant increases the mobility of CaV1.2 without altering the steady-state maintenance of cluster in young neurons and favors channel stabilization later in differentiation. Instead, mimicking phosphorylation at Ser-1700 promoted the diffusive state of CaV1.2 irrespective of the differentiation stage. Together, these results reveal that phosphorylation could contribute to the establishment of channel anchoring mechanisms depending on the neuronal differentiation state. Finally, our findings suggest a novel mechanism by which phosphorylation at the C terminus regulates calcium signaling by tuning the content of CaV1.2 at signaling complexes.

AB - For many biological processes such as ligand binding, enzymatic catalysis, or protein folding, allosteric regulation of protein conformation and dynamics is fundamentally important. One example is the bacterial adhesin FimH, where the C terminal pilin domain exerts negative allosteric control over binding of the N terminal lectin domain to mannosylated ligands on host cells. When the lectin and pilin domains are separated under shear stress, the FimH-ligand interaction switches in a so-called catch-bond mechanism from the low- to high-affinity state. So far, it has been assumed that the pilin domain is essential for the allosteric propagation within the lectin domain that would otherwise be conformationally rigid. To test this hypothesis, we generated mutants of the isolated FimH lectin domain and characterized their thermodynamic, kinetic, and structural properties using isothermal titration calorimetry, surface plasmon resonance, nuclear magnetic resonance, and X-ray techniques. Intriguingly, some of the mutants mimicked the conformational and kinetic behaviors of the full length protein and, even in absence of the pilin domain, conducted the cross-talk between allosteric sites and the mannoside-binding pocket. Thus, these mutants represent a minimalistic allosteric system of FimH, useful for further mechanistic studies and antagonist design. PMID- 29180455 TI - Hypertension: Update 2018. PMID- 29180453 TI - A hereditary spastic paraplegia-associated atlastin variant exhibits defective allosteric coupling in the catalytic core. AB - The dynamin-related GTPase atlastin (ATL) catalyzes membrane fusion of the endoplasmic reticulum and thus establishes a network of branched membrane tubules. When ATL function is compromised, the morphology of the endoplasmic reticulum deteriorates, and these defects can result in neurological disorders such as hereditary spastic paraplegia and hereditary sensory neuropathy. ATLs harness the energy of GTP hydrolysis to initiate a series of conformational changes that enable homodimerization and subsequent membrane fusion. Disease associated amino acid substitutions cluster in regions adjacent to ATL's catalytic site, but the consequences for the GTPase's molecular mechanism are often poorly understood. Here, we elucidate structural and functional defects of an atypical hereditary spastic paraplegia mutant, ATL1-F151S, that is impaired in its nucleotide-hydrolysis cycle but can still adopt a high-affinity homodimer when bound to a transition-state analog. Crystal structures of mutant proteins yielded models of the monomeric pre- and post-hydrolysis states of ATL. Together, these findings define a mechanism for allosteric coupling in which Phe151 is the central residue in a hydrophobic interaction network connecting the active site to an interdomain interface responsible for nucleotide loading.

AB - : Sacubitril/valsartan (LCZ696), a novel angiotensin receptor-neprilysin inhibitor, was recently approved for the treatment of heart failure with reduced ejection fraction. Neprilysin degrades several peptides that modulate lipid metabolism, including natriuretic peptides. In this study, we investigated the effects of 8 weeks' treatment with sacubitril/valsartan on whole-body and adipose tissue lipolysis and lipid oxidation during defined physical exercise compared with the metabolically neutral comparator amlodipine. This was a multicenter, randomized, double-blind, active-controlled, parallel-group study enrolling subjects with abdominal obesity and moderate hypertension (mean sitting systolic blood pressure >=130-180 mm Hg). Lipolysis during rest and exercise was assessed by microdialysis and [1,1,2,3,3-2H]-glycerol tracer kinetics. Energy expenditure and substrate oxidation were measured simultaneously using indirect calorimetry. Plasma nonesterified fatty acids, glycerol, insulin, glucose, adrenaline and noradrenaline concentrations, blood pressure, and heart rate were also determined. Exercise elevated plasma glycerol, free fatty acids, and interstitial glycerol concentrations and increased the rate of glycerol appearance. However, exercise-induced stimulation of lipolysis was not augmented on sacubitril/valsartan treatment compared with amlodipine treatment. Furthermore, sacubitril/valsartan did not alter energy expenditure and substrate oxidation during exercise compared with amlodipine treatment. In conclusion, sacubitril/valsartan treatment for 8 weeks did not elicit clinically relevant changes in exercise-induced lipolysis or substrate oxidation in obese patients with hypertension, implying that its beneficial cardiovascular effects cannot be explained by changes in lipid metabolism during exercise.

PMID- 29180456 TI - Body Mass Index and Vascular Disease in Men Aged 65 Years and Over: HIMS (Health In Men Study). AB - BACKGROUND: Understanding the relationship between body mass index (BMI) and vascular disease at older age has become increasingly important in the many countries where both average age and BMI are rising. METHODS AND RESULTS: In this prospective cohort study, 12 203 men (aged >=65) were recruited in 1996-1999 from the general population in Perth, Australia. To limit reverse causality, analyses excluded those with past vascular disease and the first 4 years of follow-up. During a further 8 (SD3) years of follow-up, there were 1136 first-ever major vascular events (nonfatal myocardial infarction, nonfatal stroke, or death from any vascular cause). Cox regression (adjusted for age, education, and smoking) related BMI at recruitment to incidence of major vascular events. At ages 65 to 94, the lowest risk of major vascular events was at ~ 22.5 to 25 kg/m2. In the higher BMI range (>=25 kg/m2), 5 kg/m2 higher BMI was associated with 33% higher risk of major vascular events (hazard ratio, 1.33 [95% confidence interval, 1.18 1.49]): 24% higher risk of ischemic heart disease (1.24 [1.06-1.46]); 34% higher risk of stroke (1.34 [1.11-1.63]); and 78% higher risk of other vascular death (1.78 [1.32-2.41]). In the lower BMI range, there were fewer events and no strong evidence of an association (hazard ratio per 5 kg/m2 higher BMI, 0.82 [95% confidence interval, 0.61-1.12]). CONCLUSIONS: In this population of older men, risk of major vascular events was lowest at ~ 22.5 to 25 kg/m2. Above this range, BMI was strongly related to incidence of major vascular events, with each 5 kg/m2 higher BMI associated with ~30% higher risk.

PMID- 29180458 TI - Clinical Outcomes After Ablation of the AV Junction in Patients With Atrial Fibrillation: Impact of Cardiac Resynchronization Therapy. AB - BACKGROUND: Patients with atrial fibrillation (AF) often undergo AV junction ablation (AVJA) and pacemaker implantation. Right ventricular (RV) pacing contributes to increased risk of heart failure (HF), which may be mitigated by biventricular pacing. We sought to determine the impact of AVJA concurrent with RV versus biventricular pacemaker implantation on AF and HF hospitalizations. METHODS AND RESULTS: The MarketScan Commercial and Medicare Supplemental claims database was used to select 18- to 100-year-old patients with AF with pacemaker implantation. Patients were divided into those with an RV and a biventricular pacemaker and further into those who did (AVJA+) or did not undergo concurrent ablation. Separately, the AVJA+ group was divided into those receiving RV versus biventricular pacemakers. AF and HF hospitalization rates were compared between groups after matching on demographics, comorbidities, and baseline hospitalization rates. The study included 24 361 patients, with RV (n=23 377) or biventricular (n=984) pacemakers; 1611 patients underwent AVJA. AVJA+ was associated with reduced AF hospitalization risk (RV hazard ratio [HR], 0.31; P<0.001; biventricular HR, 0.20; P=0.003) compared with no AVJA. However, HF hospitalization risk was increased for RV (HR, 1.63; P=0.001), but not biventricular (HR, 0.98; P=0.942), pacemakers. In AVJA+ patients, biventricular pacing was associated with reduced risk of HF hospitalization versus RV pacing (HR, 0.62; P=0.017). CONCLUSIONS: In a large cohort of patients with AF, AVJA+ significantly reduced AF hospitalizations, irrespective of whether an RV or a biventricular pacemaker was implanted. However, AVJA was associated with a marked HF hospitalization increase in patients with an RV pacemaker, which was ameliorated with biventricular pacing. PMID- 29180457 TI - Antihypertensive Treatment With beta-Blockade in Patients With Asymptomatic Aortic Stenosis and Association With Cardiovascular Events. AB - BACKGROUND: Patients with aortic stenosis (AS) often have concomitant hypertension. Antihypertensive treatment with a beta-blocker (Bbl) is frequently avoided because of fear of depression of left ventricular function. However, it remains unclear whether antihypertensive treatment with a Bbl is associated with increased risk of cardiovascular events in patients with asymptomatic mild to moderate AS. METHODS AND RESULTS: We did a post hoc analysis of 1873 asymptomatic patients with mild to moderate AS and preserved left ventricular ejection fraction in the SEAS (Simvastatin and Ezetimibe in Aortic Stenosis) study. Propensity-matched Cox regression and competing risk analyses were used to assess risk ratios for all-cause mortality, sudden cardiac death, and cardiovascular death. A total of 932 (50%) patients received Bbl at baseline. During a median follow-up of 4.3+/-0.9 years, 545 underwent aortic valve replacement, and 205 died; of those, 101 were cardiovascular deaths, including 40 sudden cardiovascular deaths. In adjusted analyses, Bbl use was associated with lower risk of all-cause mortality (hazard ratio 0.5, 95% confidence interval 0.3-0.7, P<0.001), cardiovascular death (hazard ratio 0.4, 95% confidence interval 0.2 0.7, P<0.001), and sudden cardiac death (hazard ratio 0.2, 95% confidence interval 0.1-0.6, P=0.004). This was confirmed in competing risk analyses (all P<0.004). No interaction was detected with AS severity (all P>0.1). CONCLUSIONS: In post hoc analyses Bbl therapy did not increase the risk of all-cause mortality, sudden cardiac death, or cardiovascular death in patients with asymptomatic mild to moderate AS. A prospective study may be warranted to determine if Bbl therapy is in fact beneficial. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov. Unique identifier: NCT00092677.

AB - OBJECTIVES: To examine, in a large, nationally representative sample of high school students, the association between bullying victimization and carrying weapons to school and to determine to what extent past experience of 1, 2, or 3 additional indicators of peer aggression increases the likelihood of weapon carrying by victims of bullying (VoBs). METHODS: National data from the 2015 Youth Risk Behavior Survey were analyzed for grades 9 to 12 (N = 15 624). VoB groups were determined by self-report of being bullied at school and additional adverse experiences: fighting at school, being threatened or injured at school, and skipping school out of fear for one's safety. Weapon carrying was measured by a dichotomized (ie, >=1 vs 0) report of carrying a gun, knife, or club on school property. VoB groups were compared with nonvictims with respect to weapon carrying by logistic regression adjusting for sex, grade, and race/ethnicity. RESULTS: When surveyed, 20.2% of students reported being a VoB in the past year, and 4.1% reported carrying a weapon to school in the past month. VoBs experiencing 1, 2, or 3 additional risk factors were successively more likely to carry weapons to school. The subset of VoBs who experienced all 3 additional adverse experiences were more likely to carry weapons to school compared with nonvictims (46.4% vs 2.5%, P < .001). CONCLUSIONS: Pediatricians should recognize that VoBs, especially those who have experienced 1 or more indicators of peer aggression in conjunction, are at substantially increased risk of weapon carrying. PMID- 29180462 TI - Global Human Trafficking and Child Victimization. AB - Trafficking of children for labor and sexual exploitation violates basic human rights and constitutes a major global public health problem. Pediatricians and other health care professionals may encounter victims who present with infections, injuries, posttraumatic stress disorder, suicidality, or a variety of other physical or behavioral health conditions. Preventing child trafficking, recognizing victimization, and intervening appropriately require a public health approach that incorporates rigorous research on the risk factors, health impact, and effective treatment options for child exploitation as well as implementation and evaluation of primary prevention programs. Health care professionals need training to recognize possible signs of exploitation and to intervene appropriately. They need to adopt a multidisciplinary, outward-focused approach to service provision, working with nonmedical professionals in the community to assist victims. Pediatricians also need to advocate for legislation and policies that promote child rights and victim services as well as those that address the social determinants of health, which influence the vulnerability to human trafficking. This policy statement outlines major issues regarding public policy, medical education, research, and collaboration in the area of child labor and sex trafficking and provides recommendations for future work. PMID- 29180463 TI - Trends of Out-of-Hospital Sudden Cardiac Death Among Children and Young Adults. AB - BACKGROUND AND OBJECTIVES: Previous estimates of sudden cardiac death in children and young adults vary significantly, and population-based studies in the United States are lacking. We sought to estimate the incidence, causes, and mortality trends of sudden cardiac death in children and young adults (1-34 years). METHODS: Demographic and mortality data based on death certificates for US residents (1-34 years) were obtained (1999-2015). Cases of sudden death and sudden cardiac death were retrieved by using the International Classification of Diseases, 10th Revision codes. RESULTS: A total of 1 452 808 subjects aged 1 to 34 years died in the United States, of which 31 492 (2%) were due to sudden cardiac death. The estimated incidence of sudden cardiac death is 1.32 per 100 000 individuals and increased with age from 0.49 (1-10 years) to 2.76 (26-34 years). During the study period, incidence of sudden cardiac death declined from 1.48 to 1.13 per 100 000 (P < .001). Mortality reduction was observed across all racial and ethnic groups with a varying magnitude and was highest in children aged 11 to 18 years. Significant disparities were found, with non-Hispanic African American individuals and individuals aged 26 to 34 years having the highest mortality rates. The majority of young children (1-10 years) died of congenital heart disease (n = 1525, 46%), whereas young adults died most commonly from ischemic heart disease (n = 5075, 29%). CONCLUSIONS: Out-of-hospital sudden cardiac death rates declined 24% from 1999 to 2015. Disparities in mortality exist across age groups and racial and ethnic groups, with non-Hispanic African American individuals having the highest mortality rates.

PMID- 29180466 TI - Synthetic Lethality of PARP Inhibitors in Combination with MYC Blockade Is Independent of BRCA Status in Triple-Negative Breast Cancer. AB - PARP inhibitors (PARPi) benefit only a fraction of breast cancer patients. Several of those patients exhibit intrinsic/acquired resistance mechanisms that limit efficacy of PARPi monotherapy. Here we show how the efficacy of PARPi in triple-negative breast cancers (TNBC) can be expanded by targeting MYC-induced oncogenic addiction. In BRCA-mutant/sporadic TNBC patients, amplification of the MYC gene is correlated with increased expression of the homologous DNA recombination enzyme RAD51 and tumors overexpressing both genes are associated with worse overall survival. Combining MYC blockade with PARPi yielded synthetic lethality in MYC-driven TNBC cells. Using the cyclin-dependent kinase inhibitor dinaciclib, which downregulates MYC expression, we found that combination with the PARPi niraparib increased DNA damage and downregulated homologous recombination, leading to subsequent downregulation of the epithelial-mesenchymal transition and cancer stem-like cell phenotypes. Notably, dinaciclib resensitized TBNC cells, which had acquired resistance to niraparib. We found that the synthetic lethal strategy employing dinaciclib and niraparib was also highly efficacious in ovarian, prostate, pancreatic, colon, and lung cancer cells. Taken together, our results show how blunting MYC oncogene addiction can leverage cancer cell sensitivity to PARPi, facilitating the clinical use of c-myc as a predictive biomarker for this treatment.Significance: Dual targeting of MYC regulated homologous recombination and PARP-mediated DNA repair yields potent synthetic lethality in triple-negative breast tumors and other aggressive tumors characterized by MYC overexpression.

AB - Overcoming acquired drug resistance remains a core challenge in the clinical management of human cancer, including in urothelial carcinoma of the bladder (UCB). Cancer stem-like cells (CSC) have been implicated in the emergence of drug resistance but mechanisms and intervention points are not completely understood. Here, we report that the proinflammatory COX2/PGE2 pathway and the YAP1 growth regulatory pathway cooperate to recruit the stem cell factor SOX2 in expanding and sustaining the accumulation of urothelial CSCs. Mechanistically, COX2/PGE2 signaling induced promoter methylation of let-7, resulting in its downregulation and subsequent SOX2 upregulation. YAP1 induced SOX2 expression more directly by binding its enhancer region. In UCB clinical specimens, positive correlations in the expression of SOX2, COX2, and YAP1 were observed, with coexpression of COX2 and YAP1 particularly commonly observed. Additional investigations suggested that activation of the COX2/PGE2 and YAP1 pathways also promoted acquired resistance to EGFR inhibitors in basal-type UCB. In a mouse xenograft model of UCB, dual inhibition of COX2 and YAP1 elicited a long-lasting therapeutic response by limiting CSC expansion after chemotherapy and EGFR inhibition. Our findings provide a preclinical rationale to target these pathways concurrently with systemic chemotherapy as a strategy to improve the clinical management of UCB.Significance: These findings offer a preclinical rationale to target the COX2 and YAP1 pathways concurrently with systemic chemotherapy to improve the clinical management of UCB, based on evidence that these two pathways expand cancer stem like cell populations that mediate resistance to chemotherapy.

AB - Activation of the receptor tyrosine kinase Axl is associated with poor outcomes in pancreatic cancer (PDAC), where it coordinately mediates immune evasion and drug resistance. Here, we demonstrate that the selective Axl kinase inhibitor BGB324 targets the tumor-immune interface to blunt the aggressive traits of PDAC cells in vitro and enhance gemcitibine efficacy in vivo Axl signaling stimulates the TBK1-NFkappaB pathway and innate immune suppression in the tumor microenvironment. In tumor cells, BGB324 treatment drove epithelial differentiation, expression of nucleoside transporters affecting gemcitabine response, and an immune stimulatory microenvironment. Our results establish a preclinical mechanistic rationale for the clinical development of Axl inhibitors to improve the treatment of PDAC patients.Significance: These results establish a preclinical mechanistic rationale for the clinical development of AXL inhibitors to improve the treatment of PDAC patients.

AB - The mitochondrial serine hydroxymethyltransferase SHMT2, which catalyzes the rate limiting step in serine catabolism, drives cancer cell proliferation, but how this role is regulated is undefined. Here, we report that the sirtuin SIRT5 desuccinylates SHMT2 to increase its activity and drive serine catabolism in tumor cells. SIRT5 interaction directly mediated desuccinylation of lysine 280 on SHMT2, which was crucial for activating its enzymatic activity. Conversely, hypersuccinylation of SHMT2 at lysine 280 was sufficient to inhibit its enzymatic activity and downregulate tumor cell growth in vitro and in vivo Notably, SIRT5 inactivation led to SHMT2 enzymatic downregulation and to abrogated cell growth under metabolic stress. Our results reveal that SHMT2 desuccinylation is a pivotal signal in cancer cells to adapt serine metabolic processes for rapid growth, and they highlight SIRT5 as a candidate target for suppressing serine catabolism as a strategy to block tumor growth.Significance: These findings reveal a novel mechanism for controlling cancer cell proliferation by blocking serine catabolism, as a general strategy to impede tumor growth.

AB - Two opposing clusters of transcription factors (TF) have been associated with the differential risks of estrogen receptor positive or negative breast cancers, but the mechanisms underlying the opposing functions of the two clusters are undefined. In this study, we identified NFIB and YBX1 as novel interactors of the estrogen receptor (ESR1). NFIB and YBX1 are both risk TF associated with progression of ESR1-negative disease. Notably, they both interacted with the ESR1 FOXA1 complex and inhibited the transactivational potential of ESR1. Moreover, signaling through FGFR2, a known risk factor in breast cancer development, augmented these interactions and further repressed ESR1 target gene expression. We therefore show that members of two opposing clusters of risk TFs associated with ESR1-positive and -negative breast cancer can physically interact. We postulate that this interaction forms a toggle between two developmental pathways affected by FGFR2 signaling, possibly offering a junction to exploit therapeutically.Significance: Binding of the transcription factors NFIB and YBX1 to the estrogen receptor can promote an estrogen-independent phenotype that can be reverted by inhibiting FGFR2 signaling.

AB - The MYC oncogene broadly promotes transcription mediated by all nuclear RNA polymerases, thereby acting as a positive modifier of global gene expression. Here, we report that MYC stimulates the transcription of DANCR, a long noncoding RNA (lncRNA) that is widely overexpressed in human cancer. We identified DANCR through its overexpression in a transgenic model of MYC-induced lymphoma, but found that it was broadly upregulated in many human cancer cell lines and cancers, including most notably in prostate and ovarian cancers. Mechanistic investigations indicated that DANCR limited the expression of cell-cycle inhibitor p21 (CDKN1A) and that the inhibitory effects of DANCR loss on cell proliferation could be partially rescued by p21 silencing. In a xenograft model of human ovarian cancer, a nanoparticle-mediated siRNA strategy to target DANCR in vivo was sufficient to strongly inhibit tumor growth. Our observations expand knowledge of how MYC drives cancer cell proliferation by identifying DANCR as a critical lncRNA widely overexpressed in human cancers.Significance: These findings expand knowledge of how MYC drives cancer cell proliferation by identifying an oncogenic long noncoding RNA that is widely overexpressed in human cancers.

AB - A distinction between indolent and aggressive disease is a major challenge in diagnostics of prostate cancer. As genetic heterogeneity and complexity may influence clinical outcome, we have initiated studies on single tumor cell genomics. In this study, we demonstrate that sparse DNA sequencing of single-cell nuclei from prostate core biopsies is a rich source of quantitative parameters for evaluating neoplastic growth and aggressiveness. These include the presence of clonal populations, the phylogenetic structure of those populations, the degree of the complexity of copy-number changes in those populations, and measures of the proportion of cells with clonal copy-number signatures. The parameters all showed good correlation to the measure of prostatic malignancy, the Gleason score, derived from individual prostate biopsy tissue cores. Remarkably, a more accurate histopathologic measure of malignancy, the surgical Gleason score, agrees better with these genomic parameters of diagnostic biopsy than it does with the diagnostic Gleason score and related measures of diagnostic histopathology. This is highly relevant because primary treatment decisions are dependent upon the biopsy and not the surgical specimen. Thus, single-cell analysis has the potential to augment traditional core histopathology, improving both the objectivity and accuracy of risk assessment and inform treatment decisions.Significance: Genomic analysis of multiple individual cells harvested from prostate biopsies provides an indepth view of cell populations comprising a prostate neoplasm, yielding novel genomic measures with the potential to improve the accuracy of diagnosis and prognosis in prostate cancer.

AB - Targeted therapeutics that are initially effective in cancer patients nearly invariably engender resistance at some stage, an inherent challenge in the use of any molecular-targeted drug in cancer settings. In this study, we evaluated resistance mechanisms arising in metastatic melanoma to MAPK pathway kinase inhibitors as a strategy to identify candidate strategies to limit risks of resistance. To investigate longitudinal responses, we developed an intravital serial imaging approach that can directly visualize drug response in an inducible RAF-driven, autochthonous murine model of melanoma incorporating a fluorescent reporter allele (tdTomatoLSL). Using this system, we visualized formation and progression of tumors in situ, starting from the single-cell level longitudinally over time. Reliable reporting of the status of primary murine tumors treated with the selective MEK1/2 inhibitor (MEKi) trametinib illustrated a time-course of initial drug response and persistence, followed by the development of drug resistance. We found that tumor cells adjacent to bundled collagen had a preferential persistence in response to MEKi. Unbiased transcriptional and kinome reprogramming analyses from selected treatment time points suggested increased c Kit and PI3K/AKT pathway activation in resistant tumors, along with enhanced expression of epithelial genes and epithelial-mesenchymal transition downregulation signatures with development of MEKi resistance. Similar trends were observed following simultaneous treatment with BRAF and MEK inhibitors aligned to standard-of-care combination therapy, suggesting these reprogramming events were not specific to MEKi alone. Overall, our results illuminate the integration of tumor-stroma dynamics with tissue plasticity in melanoma progression and provide new insights into the basis for drug response, persistence, and resistance.Significance: A longitudinal study tracks the course of MEKi treatment in an autochthonous imageable murine model of melanoma from initial response to therapeutic resistance, offering new insights into the basis for drug response, persistence, and resistance.

AB - Bromodomain and extraterminal inhibitors (BETi) are promising cancer therapies, yet prominent side effects of BETi at effective doses have been reported in phase I clinical trials. Here, we screened a panel of small molecules targeting epigenetic modulators against human metastatic melanoma cells. Cells were pretreated with or without ascorbate (vitamin C), which promotes DNA demethylation and subsequently changes the sensitivity to drugs. Top hits were structurally unrelated BETi, including JQ1, I-BET151, CPI-203, and BI-2536. Ascorbate enhanced the efficacy of BETi by decreasing acetylation of histone H4, but not H3, while exerting no effect on the expression of BRD proteins. Histone acetyltransferase 1 (HAT1), which catalyzes H4K5ac and H4K12ac, was downregulated by ascorbate mainly via the TET-mediated DNA hydroxymethylation pathway. Loss of H4ac, especially H4K5ac and H4K12ac, disrupted the interaction between BRD4 and H4 by which ascorbate and BETi blocked the binding of BRD4 to acetylated histones. Cotreatment with ascorbate and JQ1 induced apoptosis and inhibited proliferation of cultured melanoma cells. Ascorbate deficiency as modeled in Gulo /- mice diminished the treatment outcome of JQ1 for melanoma tumorgraft. In contrast, ascorbate supplementation lowered the effective dose of JQ1 needed to successfully inhibit melanoma tumors in mice. On the basis of our findings, future clinical trials with BETi should consider ascorbate levels in patients. Furthermore, ascorbate supplementation might help reduce the severe side effects that arise from BETi therapy by reducing the dosage necessary for treatment.Significance: This study shows that ascorbate can enhance the efficacy of BET inhibitors, providing a possible clinical solution to challenges arising in phase I trials from the dose-dependent side effects of this class of epigenetic therapy.

AB - TP63 is required to maintain stem cell pluripotency and suppresses the metastatic potential of cancer cells through multiple mechanisms. These functions are differentially regulated by individual isoforms, necessitating a deeper understanding of how the distinct transcriptional programs controlled by these isoforms affect cancer progression and outcomes. In this study, we conducted a pan-cancer analysis of The Cancer Genome Atlas to identify transcriptional networks regulated by TAp63 and DeltaNp63 using transcriptomes derived from epidermal cells of TAp63-/- and DeltaNp63-/- mice. Analysis of 17 cancer developmental and 27 cancer progression signatures revealed a consistent tumor suppressive pattern for TAp63. In contrast, we identified pleiotropic roles for DeltaNp63 in tumor development and found that its regulation of Lef1 was crucial for its oncogenic role. DeltaNp63 performed a distinctive role as suppressor of tumor progression by cooperating with TAp63 to modulate key biological pathways, principally cell-cycle regulation, extracellular matrix remodeling, epithelial-to mesenchymal transition, and the enrichment of pluripotent stem cells. Importantly, these TAp63 and DeltaNp63 signatures prognosticated progression and survival, even within specific stages, in bladder and renal carcinomas as well as low-grade gliomas. These data describe a novel approach for understanding transcriptional activities of TP63 isoforms across a large number of cancer types, potentially enabling identification of patient subsets most likely to benefit from therapies predicated on manipulating specific TP63 isoforms.Significance: Transcriptomic analyses of patient samples and murine knockout models highlight the prognostic role of several critical mechanisms of tumor suppression that are regulated by TP63.

We recently discovered the novel small-molecule DJ101 as a potent and metabolically stable tubulin inhibitor that can circumvent the drug efflux pumps responsible for multidrug resistance of existing tubulin inhibitors. In this study, we determined the mechanism of action of this drug. The basis for its activity was illuminated by solving the crystal structure of DJ101 in complex with tubulin at a resolution of 2.8A. Investigations of the potency of DJ101 in a panel of human metastatic melanoma cell lines harboring major clinically relevant mutations defined IC50 values of 7-10 nmol/L. In cells, DJ101 disrupted microtubule networks, suppressed anchorage-dependent melanoma colony formation, and impaired cancer cell migration. In melanoma-bearing mice, DJ101 administration inhibited tumor growth and reduced lung metastasis in the absence of observable toxicity. DJ101 also completely inhibited tumor growth in a paclitaxel-resistant xenograft mouse model of human prostate cancer (PC-3/TxR), where paclitaxel was minimally effective. Our findings offer preclinical proof of concept for the continued development of DJ101 as a next-generation tubulin inhibitor for cancer therapy.Significance: These findings offer preclinical proof of concept for the continued development of DJ101 as a next-generation antitubulin drug for cancer therapy.

AB - Radiotherapy is essential to the treatment of most solid tumors and acquired or innate resistance to this therapeutic modality is a major clinical problem. Here we show that miR-139-5p is a potent modulator of radiotherapy response in breast cancer via its regulation of genes involved in multiple DNA repair and reactive oxygen species defense pathways. Treatment of breast cancer cells with a miR-139 5p mimic strongly synergized with radiation both in vitro and in vivo, resulting in significantly increased oxidative stress, accumulation of unrepaired DNA damage, and induction of apoptosis. Several miR-139-5p target genes were also strongly predictive of outcome in radiotherapy-treated patients across multiple independent breast cancer cohorts. These prognostically relevant miR-139-5p target genes were used as companion biomarkers to identify radioresistant breast cancer xenografts highly amenable to sensitization by cotreatment with a miR-139 5p mimetic.Significance: The microRNA described in this study offers a potentially useful predictive biomarker of radiosensitivity in solid tumors and a generally applicable druggable target for tumor radiosensitization.

AB - Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal and disseminating cancer resistant to therapy, including checkpoint immunotherapies, and early tumor resection and (neo)adjuvant chemotherapy fails to improve a poor prognosis. In a transgenic mouse model of resectable PDAC, we investigated the coordinated activation of T and natural killier (NK) cells in addition to gemcitabine chemotherapy to prevent tumor recurrence. Only neoadjuvant, but not adjuvant treatment with a PD-1 antagonist effectively supported chemotherapy and suppressed local tumor recurrence and improved survival involving both NK and T cells. Local T-cell activation was confirmed by increased tumor infiltration with CD103+CD8+ T cells and neoantigen-specific CD8 T lymphocytes against the marker neoepitope LAMA4-G1254V. To achieve effective prevention of distant metastases in a complementary approach, we blocked the NK-cell checkpoint CD96, an inhibitory NK-cell receptor that binds CD155, which was abundantly expressed in primary PDAC and metastases of human patients. In gemcitabine-treated mice, neoadjuvant PD-1 blockade followed by adjuvant inhibition of CD96 significantly prevented relapse of PDAC, allowing for long-term survival. In summary, our results show in an aggressively growing transgenic mouse model of PDAC that the coordinated activation of both innate and adaptive immunity can effectively reduce the risk of tumor recurrence after surgery, facilitating long-term remission of this lethal disease.Significance: Coordinated neoadjuvant and adjuvant immunotherapies reduce the risk of disease relapse after resection of murine PDAC, suggesting this concept for future clinical trials.

AB - Increased muscle force during stretch-shortening cycles (SSCs) has been widely examined. However, the mechanisms causing increased muscle force in SSCs remain unknown. The purpose of this study was to determine the influence of residual force enhancement and elongation of attached cross-bridges on the work enhancement in SSCs. For the Control condition, skinned rabbit soleus fibers were elongated passively from an average sarcomere length of 2.4 to 3.0 MUm, activated and then actively shortened to 2.4 MUm. For the Transition condition, fibers were elongated actively from an average sarcomere length of 2.4 to 3.0 MUm. Two seconds after the end of active lengthening, fibers were actively shortened to 2.4 MUm. In the SSC condition, fibers were lengthened actively from an average sarcomere length of 2.4 to 3.0 MUm, and then immediately shortened actively to 2.4 MUm. Increased muscle force in the SSCs was quantified by the increase in mechanical work during active shortening compared to the mechanical work measured during the purely active shortening contractions. Work enhancement was significantly greater in the SSC compared to the Transition conditions. This difference was associated with the pause given between the active lengthening and shortening phase in the Transition test, which likely resulted in a reduction of the average elongation of the attached cross-bridges caused by active stretching. Since some work enhancement was still observed in the Transition condition, another factor, for example the stretch-induced residual force enhancement, must also have contributed to the work enhancement in SSCs. PMID- 29180480 TI - Motor module activation sequence and topography in the spinal cord during air stepping in human: Insights into the traveling wave in spinal locomotor circuits. AB - Coordinated locomotor muscle activity is generated by the spinal central pattern generators (CPGs), which are modulated by peripheral and supraspinal inputs. The CPGs would consist of multiple motor modules generating basic muscle activity, which are distributed rostrocaudally along the spinal cord. To activate the motor modules in proper sequence, rostrocaudally traveling waves of activation in the spinal cord are important mechanisms in the CPGs. The traveling waves of activation have been observed in nonhuman vertebrates. However, they have not yet been confirmed during human locomotion. Although, rostrocaudal wave-like activations in the spinal cord were observed during walking in humans in a previous study, the propagation shifted rostrally toward the upper lumbar segments at foot contact. Here, using an air stepping task to remove the foot contact interactions, we examined whether the traveling wave mechanism exists in the human spinal circuits based on the activation sequence of motor modules and their topography. We measured electromyographic activity of lower leg muscles during the air-stepping task. Then, we extracted motor modules (i.e., basic patterns of sets of muscle activations: muscle synergies) from the measured muscle activities using nonnegative matrix factorization method. Next, we reconstructed motoneuron (MN) activity from each module activity based on myotomal charts. We identified four types of motor modules from muscle activities during the air-stepping task. Each motor module represented different sets of synergistic muscle activations. MN clusters innervating each motor module were sequentially activated from the rostral to caudal region in the spinal cord, from the initial flexion to the last extension phase during air-stepping. The rostrocaudally sequential activation of MN clusters suggests the possibility that rostrocaudally traveling waves exist in human locomotor spinal circuits. The present results advance the understanding of human locomotor control mechanisms, and provide important insights into the evolution of locomotor networks in vertebrates. PMID- 29180481 TI - Validity and variability of xBRS: instantaneous cardiac baroreflex sensitivity. AB - Spontaneous oscillations of blood pressure (BP) and interbeat interval (IBI) may reveal important information on the underlying baroreflex control and regulation of BP We evaluated the method of continuously measured instantaneous baroreflex sensitivity by cross correlation (xBRS) validating its mean value against the gold standard of phenylephrine (Phe) and nitroprusside (SNP) bolus injections, and focusing on its spontaneous changes quantified as variability around the mean. For this purpose, we analyzed data from an earlier study of eight healthy males (aged 25-46 years) who had received Phe and SNP in conditions of baseline and autonomic blocking agents: atropine, propranolol, and clonidine. Average xBRS corresponds well to Phe/SNP-BRS, with xBRS levels ranging from 1.2 (atropine) to 102 msec/mmHg (subject asleep under clonidine). Time shifts from BP- to IBI signal increased from <=1 sec (maximum correlations within the current heartbeat) to 3-5 sec (under atropine). Plotted on a logarithmic vertical scale, xBRS values show 40% variability (defined as SD/mean) over the whole range in the various conditions, except twice when the subjects had fallen asleep and it dropped to 20%. The xBRS oscillates at frequencies of 0.1 Hz and lower, dominant between 0.02-0.05 Hz. Although xBRS is the result of IBI/BP-changes, no linear coherence was found in the cross-spectra of the xBRS-signal and IBI or BP We speculate that the level of variability in the xBRS-signal may act as a probe into the central nervous condition, as evidenced in the two subjects who fell asleep with high xBRS and only 20% of relative variation. PMID- 29180483 TI - Decoding spatial attention with EEG and virtual acoustic space. AB - Decoding spatial attention based on brain signals has wide applications in brain computer interface (BCI). Previous BCI systems mostly relied on visual patterns or auditory stimulation (e.g., loudspeakers) to evoke synchronous brain signals. There would be difficulties to cover a large range of spatial locations with such a stimulation protocol. The present study explored the possibility of using virtual acoustic space and a visual-auditory matching paradigm to overcome this issue. The technique has the flexibility of generating sound stimulation from virtually any spatial location. Brain signals of eight human subjects were obtained with a 32-channel Electroencephalogram (EEG). Two amplitude-modulated noise or speech sentences carrying distinct spatial information were presented concurrently. Each sound source was tagged with a unique modulation phase so that the phase of the recorded EEG signals indicated the sound being attended to. The phase-tagged sound was further filtered with head-related transfer functions to create the sense of virtual space. Subjects were required to pay attention to the sound source that best matched the location of a visual target. For all the subjects, the phase of a single sound could be accurately reflected over the majority of electrodes based on EEG responses of 90 s or less. The electrodes providing significant decoding performance on auditory attention were fewer and may require longer EEG responses. The reliability and efficiency of decoding with a single electrode varied with subjects. Overall, the virtual acoustic space protocol has the potential of being used in practical BCI systems. PMID- 29180484 TI - Repeated bouts of resistance exercise with short recovery periods activates mTOR signaling, but not protein synthesis, in mouse skeletal muscle. AB - The recovery period between bouts of exercise is one of the major factors influencing the effects of resistance exercise, in addition to exercise intensity and volume. However, the effects of shortening the recovery time between bouts of resistance exercise on subsequent protein synthesis remain unclear. In this study, we investigated the consequences of shortening the recovery time between bouts of resistance exercise on protein synthesis and related processes in mouse skeletal muscles. Eighteen male C57BL/6J mice were randomly subjected to three bouts of resistance exercise with 72 (72H), 24 (24H), or 8 h (8H) of recovery periods between bouts. Resistance exercise, consisting of five sets of 3 s * 10 isometric contractions with 3 min rest between sets, was elicited on the right tibialis anterior muscle via percutaneous electrical stimulation on the deep peroneal nerve under isoflurane anesthesia. The left muscle served as an internal control. Six hours after the third bout of exercise, protein synthesis was found to be activated in the 72H and 24H groups, but not in the 8H group. Phosphorylation of p70S6K at Thr 389, a marker of mammalian target of rapamycin (mTOR) signaling, was increased in all groups, with the 8H group showing the highest magnitude. In contrast, protein carbonylation was observed only in mice in the 8H group. These results suggest that repeated bouts of resistance exercise with 8 h of recovery periods do not effectively increase the levels of muscle protein synthesis despite activation of the mTOR signaling pathway, which likely involves oxidative stress. PMID- 29180482 TI - Deep-targeted sequencing of endothelial nitric oxide synthase gene exons uncovers exercise intensity and ethnicity-dependent associations with post-exercise hypotension. AB - In previous studies, we found an endothelial nitric oxide synthase gene (NOS3) variant rs2070744 associated with the ambulatory blood pressure (BP) response following bouts of moderate and vigorous intensity acute exercise, termed post exercise hypotension (PEH). In a validation cohort, we sequenced NOS3 exons for associations with PEH Obese (30.9 +/- 3.6 kg.m-2) African American (n = 14) [AF] and Caucasian (n = 9) adults 42.0 +/- 9.8 years with hypertension (139.8 +/- 10.4/84.6 +/- 6.2 mmHg) performed three random experiments: bouts of vigorous and moderate intensity cycling and control. Subjects were attached to an ambulatory BP monitor for 19 h. We performed deep-targeted exon sequencing with the Illumina TruSeq Custom Amplicon kit. Variant genotypes were coded as number of minor alleles (#MA) and selected for additional statistical analysis based upon Bonferonni or Benjamini-Yekutieli multiple testing-corrected P-values under time adjusted linear models for 19 hourly BP measurements for each subject. After vigorous intensity over 19 h, among NOS3 variants passing multiple testing thresholds, as the #MA increased in rs891512 (P = 6.4E-04), rs867225 (P = 6.5E 04), rs743507 (P = 2.6E-06), and rs41483644 (P = 2.4E-04), systolic (SBP) decreased from 17.5 to 33.7 mmHg; and in rs891512 (P = 9.7E-05), rs867225 (P = 2.6E-05), rs41483644 (P = 1.6E-03), rs3730009 (P = 2.6E-04), and rs77325852 (P = 5.6E-04), diastolic BP decreased from 11.1 mmHg to 20.3 mmHg among AF only. In contrast, after moderate intensity over 19 h in NOS3 rs3918164, as the #MA increased, SBP increased by 16.6 mmHg (P = 2.4E-04) among AF only. NOS3 variants exhibited associations with PEH after vigorous, but not moderate intensity exercise among AF only. NOS3 should be studied further for its effects on PEH in a large, ethnically diverse sample of adults with hypertension to confirm our findings. PMID- 29180485 TI - Validation of whole room indirect calorimeters: refinement of current methodologies. AB - Whole room indirect calorimeter (WRIC) validation techniques consist of propane combustion (PC) or infusion of mixed carbon dioxide (CO2) and nitrogen (N2) by a precision blender (PB). To determine the best method, PC of 6, 10, 22-h and PB infusions of 6, 10, and 14-h, were conducted. The 14-h infusion consisted of two metabolic settings. Energy expenditure (EE; kJ), ventilation (V; liters/min) of oxygen (VO2), VCO2, and respiratory quotient (VCO2/VO2) obtained from the WRIC were extrapolated to the respective test durations and compared to similarly calculated values. Moreover, accurate equations (AE) were derived to correct infusions for additional N2 As a final evaluation of a PC validated WRIC, weight maintenance (WM), energy balance (EB), respiratory quotient (RQ), and food quotients (FQ) were determined in 22 subjects who had repeat 24-h EE measurements. Statistical analyses (P < 0.05) were conducted (SPSS, version 23). Significant differences in RQ existed between PC and stoichiometry after 6-h. Errors for the rest of the PC tests ranged from -1.5 +/- 2.4 (VCO2) to 2.8 +/- 4.6% (EE). When compared with the WRIC, all uncorrected metabolic parameters for six and 10-h PB infusions were significantly different with errors from -12.8 +/- 1.6 (VO2) to 6.0 +/- 2.8% (RQ). The AE reduced the magnitude of errors to -12.4 +/- 1.5 (RQ) to 2.2 +/- 3.0% (RQ). The PB infusion with two settings showed similar performance. No differences in WM, EB, RQ, or FQ existed in the subjects. In conclusion, 10-h PC tests are sufficient for validating WRICs. PMID- 29180488 TI - Rhesus Macaque Myeloid-Derived Suppressor Cells Demonstrate T Cell Inhibitory Functions and Are Transiently Increased after Vaccination. AB - Myeloid-derived suppressor cells (MDSCs) are major regulators of T cell responses in several pathological conditions. Whether MDSCs increase and influence T cell responses in temporary inflammation, such as after vaccine administration, is unknown. Using the rhesus macaque model, which is critical for late-stage vaccine testing, we demonstrate that monocytic (M)-MDSCs and polymorphonuclear (PMN) MDSCs can be detected using several of the markers used in humans. However, whereas rhesus M-MDSCs lacked expression of CD33, PMN-MDSCs were identified as CD33+ low-density neutrophils. Importantly, both M-MDSCs and PMN-MDSCs showed suppression of T cell proliferation in vitro. The frequency of circulating MDSCs rapidly and transiently increased 24 h after vaccine administration. M-MDSCs infiltrated the vaccine injection site, but not vaccine-draining lymph nodes. This was accompanied by upregulation of genes relevant to MDSCs such as arginase 1, IDO1, PDL1, and IL-10 at the injection site. MDSCs may therefore play a role in locally maintaining immune balance during vaccine-induced inflammation. PMID- 29180486 TI - The IFN Response in Bats Displays Distinctive IFN-Stimulated Gene Expression Kinetics with Atypical RNASEL Induction. AB - Bats host a large number of zoonotic viruses, including several viruses that are highly pathogenic to other mammals. The mechanisms underlying this rich viral diversity are unknown, but they may be linked to unique immunological features that allow bats to act as asymptomatic viral reservoirs. Vertebrates respond to viral infection by inducing IFNs, which trigger antiviral defenses through IFN stimulated gene (ISG) expression. Although the IFN system of several bats is characterized at the genomic level, less is known about bat IFN-mediated transcriptional responses. In this article, we show that IFN signaling in bat cells from the black flying fox (Pteropus alecto) consists of conserved and unique ISG expression profiles. In IFN-stimulated cells, bat ISGs comprise two unique temporal subclusters with similar early induction kinetics but distinct late-phase declines. In contrast, human ISGs lack this decline phase and remained elevated for longer periods. Notably, in unstimulated cells, bat ISGs were expressed more highly than their human counterparts. We also found that the antiviral effector 2-5A-dependent endoribonuclease, which is not an ISG in humans, is highly IFN inducible in black flying fox cells and contributes to cell intrinsic control of viral infection. These studies reveal distinctive innate immune features that may underlie a unique virus-host relationship in bats. PMID- 29180487 TI - Toxoplasma gondii Inactivates Human Plasmacytoid Dendritic Cells by Functional Mimicry of IL-10. AB - Plasmacytoid dendritic cells (pDCs) are the major producers of IFN-alpha, an antiviral cytokine involved in immunomodulation and control of HIV type 1 replication, whereas Toxoplasma gondii is a life-threatening opportunistic infection in AIDS patients. During infection with HIV type 1, human pDCs decrease in circulation and remaining pDC produce lower amounts of IFN-alpha in response to viral stimulation. In this study, we investigated the impact of coinfection with T. gondii on the innate virus-directed responses of human pDCs. Using intracellular flow cytometry and fluorescence microscopy, we determined that T. gondii invaded but did not induce IFN-alpha or TNF-alpha in human pDC. However, T. gondii inhibited IFN-alpha and TNF-alpha produced in response to HSV and HIV, thus functionally inactivating pDC. IFN-alpha production was inhibited only in cells infected by T. gondii, which inhibited neither uptake of GFP-HSV nor localization of TLR9 in CD71+ endosomes, directing us to investigate downstream events. Using imaging flow cytometry, we found that both T. gondii and IL-10 inhibited virus-induced nuclear translocation, but not phosphorylation, of IFN response factor 7. Blockade of IFN response factor 7 nuclear translocation and inhibition of the IFN-alpha response was partially reversed by a deficiency in the T. gondii-derived ROP16 kinase, known to directly phosphorylate STAT3, a critical mediator of IL-10's anti-inflammatory effects. Taken together, our results indicate that T. gondii suppresses pDC activation by mimicking IL-10's regulatory effects through an ROP16 kinase-dependent mechanism. Our findings further imply a convergent mechanism of inhibition of TLR signaling by T. gondii and IL-10 and suggest potential negative consequences of HIV/T. gondii coinfection. PMID- 29180489 TI - Downregulation of NFAT3 Due to Lack of T-Box Transcription Factor TBX5 Is Crucial for Cytokine Expression in T Cells. AB - The NFAT family transcription factors play crucial roles in immunological and other biological activities. NFAT3 is rarely expressed in T cells, and the mechanisms and significance of the specific NFAT3 downregulation in T cells have been unknown. In human CD4+ T cells, overexpression of NFAT1 and NFAT3 enhanced and suppressed IL-2 expression, respectively. NFAT3 downregulation in Jurkat cells using RNA interference technology augmented IL-2 expression, whereas a knockdown of NFAT1, NFAT2, and NFAT4 suppressed it. The promoter/enhancer activity of the NFAT-binding site in the IL-2 gene was upregulated and downregulated by NFAT1 and NFAT3, respectively. A study employing NFAT1/NFAT3 chimeric molecules revealed that the region in NFAT3 responsible for NFAT promoter activity inhibition was located within its N-terminal transactivation domain, Ca2+-regulatory domain, and DNA-binding domain. Downregulation of NFAT3 expression in T cells is mediated by lower chromatin accessibility and enhancer activity in its promoter in comparison with aortic smooth muscle cells expressing endogenous NFAT3. The binding sites of T-box transcription factor TBX5 and NK-2 transcription factor-related locus 5 Nkx2.5, which were expressed at higher levels in aortic smooth muscle cells than in T cells, were located within the 387 to +97 NFAT3 promoter region, exhibiting the maximum enhancer activity. Mutating the binding site of TBX5 but not Nkx2.5 diminished the NFAT3 promoter activity, whereas the overexpression of TBX5 enhanced it. Introduction of TBX5 into CD4+ T cells enhanced the expression of NFAT3 and suppressed that of IL-2. TBX5 deficiency-mediated downregulation of NFAT3 is crucial for the high cytokine producing activity of T cells. PMID- 29180490 TI - Identity and Diversity of Human Peripheral Th and T Regulatory Cells Defined by Single-Cell Mass Cytometry. AB - Human CD3+CD4+ Th cells, FOXP3+ T regulatory (Treg) cells, and T regulatory type 1 (Tr1) cells are essential for ensuring peripheral immune response and tolerance, but the diversity of Th, Treg, and Tr1 cell subsets has not been fully characterized. Independent functional characterization of human Th1, Th2, Th17, T follicular helper (Tfh), Treg, and Tr1 cells has helped to define unique surface molecules, transcription factors, and signaling profiles for each subset. However, the adequacy of these markers to recapitulate the whole CD3+CD4+ T cell compartment remains questionable. In this study, we examined CD3+CD4+ T cell populations by single-cell mass cytometry. We characterize the CD3+CD4+ Th, Treg, and Tr1 cell populations simultaneously across 23 memory T cell-associated surface and intracellular molecules. High-dimensional analysis identified several new subsets, in addition to the already defined CD3+CD4+ Th, Treg, and Tr1 cell populations, for a total of 11 Th cell, 4 Treg, and 1 Tr1 cell subsets. Some of these subsets share markers previously thought to be selective for Treg, Th1, Th2, Th17, and Tfh cells, including CD194 (CCR4)+FOXP3+ Treg and CD183 (CXCR3)+T bet+ Th17 cell subsets. Unsupervised clustering displayed a phenotypic organization of CD3+CD4+ T cells that confirmed their diversity but showed interrelation between the different subsets, including similarity between Th1-Th2 Tfh cell populations and Th17 cells, as well as similarity of Th2 cells with Treg cells. In conclusion, the use of single-cell mass cytometry provides a systems level characterization of CD3+CD4+ T cells in healthy human blood, which represents an important baseline reference to investigate abnormalities of different subsets in immune-mediated pathologies.

Over the past 2 decades, technological advancements have resulted in the emergence of miniaturized handheld ultrasound equipment that is compact and battery operated, and handheld echocardiography can be readily performed at the point of care with reasonable image quality. The simplicity of use, availability at the patient's bedside, easy transportability, and relatively low cost have encouraged physicians to use these devices for prompt medical decision making. As a consequence, the use of handheld echocardiography is on the rise even among nonechocardiographers (intensivists, emergency care physicians, internists, and medical students). One of the real utilities of ultrasound-augmented clinical diagnosis is in evaluating patients efficiently and selecting patients for appropriate downstream diagnostic testing including comprehensive echocardiography. Although clinical evidence supports the use of handheld devices in various clinical settings and by different users, proficiency in point-of-care ultrasound requires dedicated training in both performance and interpretation. This review summarizes the existing literature on the use of handheld echocardiography in conducting focused cardiac examinations: its training requirements, challenges, opportunities, and future perspectives in the care of the cardiovascular patient.

PMID- 29180507 TI - CEBPA mutational analysis in acute myeloid leukaemia by a laboratory-developed next-generation sequencing assay. AB - AIM: The presence of biallelic CEBPA mutations is a favourable prognostic feature in acute myeloid leukaemia (AML). CEBPA mutations are currently identified through conventional capillary sequencing (CCS). With the increasing adoption of next-generation sequencing (NGS) platforms, challenges with regard to amplification efficiency of CEBPA due to the high GC content may be encountered, potentially resulting in suboptimal coverage. Here, the performance of an amplicon-based NGS method using a laboratory-developed CEBPA-specific Nextera XT (CEBNX) was evaluated. METHODS: Mutational analyses of the CEBPA gene of 137 AML bone marrow or peripheral blood retrospective specimens were performed by the amplification of the CEBPA gene using the Expand Long Range dNTPack and the amplicons processed by CCS and NGS. CEBPA-specific libraries were then constructed using the Nextera XT V.2 kit. All FASTQ files were then processed with the MiSeq Reporter V.2.6.2.3 using the PCR Amplicon workflow via the customised CEBPA-specific manifest file. The variant calling format files were analysed using the Illumina Variant Studio V.2.2. RESULTS: A coverage per base of 3631X to 28184X was achieved. 22 samples (16.1%) were found to contain CEBPA mutations, with variant allele frequencies (VAF) ranging from 3.8% to 58.2%. Taking CCS as the 'gold standard', sensitivity and specificity of 97% and 97% was achieved. For the transactivation domain 2 polymorphism (c.584_589dupACCCGC/p.His195_Pro196dup), the CEBNX achieved 100% sensitivity and 100% specificity relative to CCS. CONCLUSIONS: Our laboratory-developed CEBNX workflow shows high coverage and thus overcomes the challenges associated with amplification efficiency and low coverage of CEBPA. Therefore, our assay is suitable for deployment in the clinical laboratory. PMID- 29180508 TI - Incidence and serotype characterisation of Streptococcus agalactiae in a Portuguese hospital. AB - AIMS: Streptococcus agalactiae, commonly known as group B Streptococcus (GBS), has been recognised as a worldwide causative pathogenic agent of neonatal sepsis, meningitis and pneumonia. To better understand the behaviour of S. agalactiae in pregnant women from a hospital from the North of Portugal, retrospective analyses were performed to describe epidemiological, clinical and microbiological characteristics of the isolates obtained. METHODS: Based on laboratorial records and the hospital's patient files, a 6-year retrospective study was performed to analyse S. agalactiae isolates from screened pregnant women between 35 and 37 weeks of gestation and hospitalised neonates from pregnant women between 24 and 41 weeks of gestation admitted in Hospital Pedro Hispano. Serotype characterisation was also performed in 67 GBS strains. RESULTS: In 6692 pregnant women between 35 and 37 weeks of gestation screened between 2011 and 2016, a total of 1377 S. agalactiae isolates (21%) were found. A high percentage (40%) of unknown colonisation status among hospitalised neonates from pregnant women between 24 and 41 weeks of gestations was also found. The incidence of neonatal sepsis was 8.7 (95% CI 7.0 to 10.8) cases per 1000 live births. Regarding serotype characterisation, serotype III (22.4%) was the most frequent, followed by serotype Ia (19.4%) and serotypes Ib and V (both with 17.9%). CONCLUSION: High epidemiological values of GBS colonisation and incidence were found in this study. In Portugal studies on the epidemiology and behaviour of S. agalactiae remain limited, reinforcing the importance and need for S. agalactiae screening across the country. PMID- 29180509 TI - Subcellular localisation of the stem cell markers OCT4, SOX2, NANOG, KLF4 and c MYC in cancer: a review. AB - The stem cell markers octamer-binding transcription factor 4, sex-determining region Y-box 2, NANOG, Kruppel-like factor 4 and c-MYC are key factors in inducing pluripotency in somatic cells, and they have been used to detect cancer stem cell subpopulations in a range of cancer types. Recent literature has described the subcellular localisation of these markers and their potential implications on cellular function. This is a relatively complex and unexplored area of research, and the extent of the effect that subcellular localisation has on cancer development and growth is largely unknown. This review analyses this area of research in the context of the biology of stem cells and cancer and explores the potential modulating effect of subcellular localisation of these proteins as supported by the literature.

AB - The cellular response to DNA damage is an intricate mechanism that involves the interplay among several pathways. In this study, we provide evidence of the roles of the polyadenylation factor cleavage stimulation factor 50 (CstF-50) and the ubiquitin (Ub) escort factor p97 as cofactors of BRCA1/BARD1 E3 Ub ligase, facilitating chromatin remodeling during the DNA damage response (DDR). CstF-50 and p97 formed complexes with BRCA1/BARD1, Ub, and some BRCA1/BARD1 substrates, such as RNA polymerase (RNAP) II and histones. Furthermore, CstF-50 and p97 had an additive effect on the activation of the ubiquitination of these BRCA1/BARD1 substrates during DDR. Importantly, as a result of these functional interactions, BRCA1/BARD1/CstF-50/p97 had a specific effect on the chromatin structure of genes that were differentially expressed. This study provides new insights into the roles of RNA processing, BRCA1/BARD1, the Ub pathway, and chromatin structure during DDR.

AB - Rpc34 is a subunit of the Rpc82/34/31 subcomplex residing on the DNA-binding cleft of RNA polymerase (Pol) III. Rpc34 contains a structurally flexible N terminal tandem winged-helix (tWH) domain related to the TFIIE transcription factor. While the second WH (WH2) fold of the tWH domain is known to function in DNA melting activity during transcription initiation, the functional role of the WH1 fold is unknown. In this study, we generated a series of new Rpc34 tWH mutants conferring a cold-sensitive growth phenotype. We found that the tWH mutations severely compromised in vitro transcription activity due to destabilization of the preinitiation complex (PIC). Site-specific protein photo cross-linking analysis indicated that the tWH domain persistently interacts with protein subunits of the Pol III cleft in the PIC and the ternary elongation complex (TEC). Furthermore, purified Pol III proteins with tWH mutations also showed reduced efficiency in RNA elongation. Our study results suggest that the tWH domain is an important protein module above the Pol III cleft that integrates protein and nucleic acid interactions for initiation and elongation.

PMID- 29180513 TI - Glucose deprivation induces primary cilium formation through mTORC1 inactivation. AB - Primary cilia are antenna-like sensory organelles extending from the surface of many cell types that play critical roles in tissue development and homeostasis. Here, we examined the effect of nutrient status on primary cilium formation. Glucose deprivation significantly increased the number of ciliated cells under both serum-fed and -starved conditions. Glucose deprivation-induced ciliogenesis was suppressed by overexpression of Rheb, an activator of the mammalian target of rapamycin complex-1 (mTORC1). Inactivating mTORC1 by rapamycin treatment or Raptor knockdown significantly promoted ciliogenesis. These results indicate that glucose deprivation promotes primary cilium formation through mTORC1 inactivation. Rapamycin treatment did not promote autophagy or degradation of OFD1, a negative regulator of ciliogenesis. In contrast, rapamycin treatment increased the level of the p27KIP1 (also known as CDKN1B) cyclin-dependent kinase inhibitor, and rapamycin-induced ciliogenesis was abrogated in p27KIP1-depleted cells. These results indicate that mTORC1 inactivation induces ciliogenesis through p27KIP1 upregulation, but not through autophagy. By contrast, glucose deprivation or rapamycin treatment shortened the cilium length. Thus, glucose deprivation and subsequent inactivation of mTORC1 play dual roles in ciliogenesis: triggering primary cilium formation and shortening cilium length.This article has an associated First Person interview with the first author of the paper. PMID- 29180514 TI - Protein localization screening in vivo reveals novel regulators of multiciliated cell development and function. AB - Multiciliated cells (MCCs) drive fluid flow in diverse tubular organs and are essential for the development and homeostasis of the vertebrate central nervous system, airway and reproductive tracts. These cells are characterized by dozens or hundreds of motile cilia that beat in a coordinated and polarized manner. In recent years, genomic studies have not only elucidated the transcriptional hierarchy for MCC specification but also identified myriad new proteins that govern MCC ciliogenesis, cilia beating and cilia polarization. Interestingly, this burst of genomic data has also highlighted that proteins with no obvious role in cilia do, in fact, have important ciliary functions. Understanding the function of proteins with little prior history of study presents a special challenge, especially when faced with large numbers of such proteins. Here, we define the subcellular localization in MCCs of ~200 proteins not previously implicated in cilia biology. Functional analyses arising from the screen provide novel links between actin cytoskeleton and MCC ciliogenesis. PMID- 29180516 TI - The EGFR odyssey - from activation to destruction in space and time. AB - When cell surface receptors engage their cognate ligands in the extracellular space, they become competent to transmit potent signals to the inside of the cell, thereby instigating growth, differentiation, motility and many other processes. In order to control these signals, activated receptors are endocytosed and thoroughly curated by the endosomal network of intracellular vesicles and proteolytic organelles. In this Review, we follow the epidermal growth factor (EGF) receptor (EGFR) from ligand engagement, through its voyage on endosomes and, ultimately, to its destruction in the lysosome. We focus on the spatial and temporal considerations underlying the molecular decisions that govern this complex journey and discuss how additional cellular organelles - particularly the ER - play active roles in the regulation of receptor lifespan. In summarizing the functions of relevant molecules on the endosomes and the ER, we cover the order of molecular events in receptor activation, trafficking and downregulation, and provide an overview of how signaling is controlled at the interface between these organelles. PMID- 29180515 TI - Migration against the direction of flow is LFA-1-dependent in human hematopoietic stem and progenitor cells. AB - The recruitment of immune cells during inflammation is regulated by a multi-step cascade of cell rolling, activation, adhesion and transmigration through the endothelial barrier. Similarly, hematopoietic stem and progenitor cells (HSPCs) use this pathway to migrate and home to the bone marrow. After selectin-mediated braking, HSPCs migrate on adhesion ligands presented by the vascular endothelium including ICAM-1, VCAM-1 or MAdCAM-1. Here, we report that both the KG1a stem cell line and primary bone marrow CD34+ HSPCs can migrate against the direction of fluid flow on surfaces coated with cell adhesion molecules (CAMs), a behavior thus far only reported in T lymphocytes. We demonstrate that KG1a cells and primary HSPCs migrate upstream on surfaces presenting ICAM-1, downstream on surfaces presenting VCAM-1, and both upstream and downstream on surfaces presenting MAdCAM-1. In addition, we demonstrate that KG1a cells and HSPCs display upstream migration both on surfaces with multiple CAMs, as well as on human umbilical vein endothelial cell (HUVEC) monolayers. By blocking with monoclonal antibodies, we show that lymphocyte function-associated antigen-1 (LFA 1) is the key receptor responsible for upstream migration on the endothelium during the trafficking of HSPCs to the bone marrow.This article has an associated First Person interview with the first author of the paper. PMID- 29180518 TI - Unintentional injury mortality among indigenous communities of Taiwan: trends from 2002 to 2013 and evaluation of a community-based intervention. AB - INTRODUCTION: Indigenous communities in Taiwan shoulder a disproportionate burden of unintentional injury fatalities. We compare unintentional injury mortality rate trends among Taiwan's indigenous communities and the general population from 2002 to 2013, and evaluate potential impact of a community-based injury prevention programme on indigenous unintentional injury death rates. METHODS: Standardised and crude unintentional injury mortality rates were obtained from Taiwan government reports. Segmented linear regression was used to estimate and compare unintentional injury mortality rate trends before and after the intervention. RESULTS: Between 2002 and 2013, unintentional injury mortality rates among Taiwan's indigenous population significantly declined by about 4.5 deaths per 100 000 each year (p<0.0001). During that time, the unintentional injury mortality rate ratio between indigenous Taiwanese and the general population significantly decreased by approximately 1% each successive year (p=0.02). However, we were unable to detect evidence that the 'Healthy and Safe Tribe' programme was associated with a statistically significant decrease in the unintentional injury mortality rate trend among indigenous persons (p=0.81). CONCLUSION: Taiwanese indigenous communities remain at significantly higher risk of unintentional injury death, though the gap may be slowly narrowing. We found no evidence that the 'Healthy and Safe Tribe' indigenous injury-prevention programme significantly contributed to the nationwide decline in unintentional injury mortality among indigenous Taiwanese communities from 2009 to 2013. Future interventions to address the disproportionate burden of unintentional injury fatalities among indigenous Taiwanese should consider interventions with wider coverage of the indigenous population, and complementing grass roots led community-based interventions with structural policy interventions as well. PMID- 29180517 TI - RDGBalpha localization and function at membrane contact sites is regulated by FFAT-VAP interactions. AB - Phosphatidylinositol transfer proteins (PITPs) are essential regulators of PLC signalling. The PI transfer domain (PITPd) of multi-domain PITPs is reported to be sufficient for in vivo function, questioning the relevance of other domains in the protein. In Drosophila photoreceptors, loss of RDGBalpha, a multi-domain PITP localized to membrane contact sites (MCSs), results in multiple defects during PLC signalling. Here, we report that the PITPd of RDGBalpha does not localize to MCSs and fails to support function during strong PLC stimulation. We show that the MCS localization of RDGBalpha depends on the interaction of its FFAT motif with dVAP-A. Disruption of the FFAT motif (RDGBFF/AA) or downregulation of dVAP A, both result in mis-localization of RDGBalpha and are associated with loss of function. Importantly, the ability of the PITPd in full-length RDGBFF/AA to rescue mutant phenotypes was significantly worse than that of the PITPd alone, indicating that an intact FFAT motif is necessary for PITPd activity in vivo Thus, the interaction between the FFAT motif and dVAP-A confers not only localization but also intramolecular regulation on lipid transfer by the PITPd of RDGBalpha.

PMID- 29180519 TI - Understanding the resistance to creating safer ice hockey: essential points for injury prevention. AB - INTRODUCTION: Despite the known negative health outcomes of concussions in minor level boys' hockey, there has been significant resistance to creating a safer game with less body checking. METHODS: To better understand cultural barriers that prevent making the sport safer for youth and adolescents, semistructured interviews, with 20 ice hockey stakeholders, were conducted and analysed using thematic analysis. RESULTS: Through this analysis, two primary concepts arose from respondents. The first concept is that body checking, despite the harm it can cause, should be done in a respectful sportsmanlike fashion. The second concept is the contradiction that the game of ice hockey is both dynamic and unchangeable. DISCUSSION: Using structural functionalist theory, we propose an argument that the unfortunate perpetuation of violence and body checking in youth ice hockey serves to maintain the social order of the game and its culture. Any strategies aimed at modifying and promoting healthy behaviour in the game should take these concepts into account.

AB - Glecaprevir and pibrentasvir are hepatitis C virus (HCV) pangenotypic inhibitors targeting NS3/4A protease and NS5A, respectively. This once-daily, fixed-dose combination regimen demonstrated high sustained virologic response 12 weeks postdosing (SVR12) rates in CERTAIN-1 and CERTAIN-2 studies in Japanese HCV infected patients, with a low virologic failure rate (1.2%). There were no virologic failures among direct-acting antiviral (DAA)-treatment-naive genotype 1a (GT1a) (n = 4)-, GT1b (n = 128)-, and GT2 (n = 97)-infected noncirrhotic patients treated for 8 weeks or among GT1b (n = 38)- or GT2 (n = 20)-infected patients with compensated cirrhosis treated for 12 weeks. Two of 33 DAA experienced and 2 of 12 GT3-infected patients treated for 12 weeks experienced virologic failure. Pooled resistance analysis, grouped by HCV subtype, treatment duration, prior treatment experience, and cirrhosis status, was conducted. Among DAA-naive GT1b-infected patients, the baseline prevalence of NS3-D168E was 1.2%, that of NS5A-L31M was 3.6%, and that of NS5A-Y93H was 17.6%. Baseline polymorphisms in NS3 or NS5A were less prevalent in GT2, with the exception of the common L/M31 polymorphism in NS5A. Among DAA-experienced GT1b-infected patients (30/32 daclatasvir plus asunaprevir-experienced patients), the baseline prevalence of NS3-D168E/T/V was 48.4%, that of NS5A-L31F/I/M/V was 81.3%, that of the NS5A P32deletion was 6.3%, and that of NS5A-Y93H was 59.4%. Common baseline polymorphisms in NS3 and/or NS5A had no impact on treatment outcomes in GT1- and GT2-infected patients; the impact on GT3-infected patients could not be assessed due to the enrollment of patients infected with diverse subtypes and the limited number of patients. The glecaprevir-pibrentasvir combination regimen allows a simplified treatment option without the need for HCV subtyping or baseline resistance testing for DAA-naive GT1- or GT2-infected patients.

PMID- 29180523 TI - Efficacy of Novel Antistaphylococcal Ectolysin P128 in a Rat Model of Methicillin Resistant Staphylococcus aureus Bacteremia. AB - Staphylococcus aureus causes systemic infections with high morbidity and mortality, and the emergence of drug-resistant strains is a rapidly growing clinical concern. Novel therapeutic agents are required to tackle S. aureus infections. P128 is a bacteriophage-derived chimeric ectolysin with potent and rapid bactericidal activity against S. aureus In the present study, the efficacy of P128 was evaluated in a newly developed rat model of S. aureus bacteremia. Prior to in vivo testing, P128 was shown to be stable in whole blood by incubation in rat blood for up to 6 h and testing its bactericidal activity against the methicillin-resistant S. aureus isolate USA300. Rats succumbed to intravenous challenge with 109 CFU of S. aureus USA300, resulting in 80 to 100% mortality by day 14. Evaluation of the bacterial load in various organs at 96 h postinfection revealed high bacterial counts in the kidney, and this correlated with the presence of renal abscesses. Treatment of infected animals with P128 either by intravenous bolus administration via tail vein or by 1-h infusion via the jugular vein at 2 h postinfection resulted in the dose-dependent survival of rats. P128 treatment also resulted in very few or no abscesses in the kidneys. These data show that P128 is stable in the physiological milieu and that intravenous treatment with P128 is highly effective in rescuing rats from S. aureus bacteremia. P128 can be a novel therapeutic option for treatment of S. aureus systemic infections. PMID- 29180524 TI - Safety and Pharmacokinetics of the Aminomethylcycline Antibiotic Omadacycline Administered to Healthy Subjects in Oral Multiple-Dose Regimens. AB - Omadacycline, a first-in-class aminomethylcycline antibiotic, is related to tetracyclines but is structurally modified to circumvent mechanisms of resistance to tetracyclines. Omadacycline demonstrates potent activity against a broad range of pathogens, including drug-resistant strains, and is in late-stage development for treatment of acute bacterial skin and skin structure infections and community acquired bacterial pneumonia. Previous studies support an intravenous-to-oral transition regimen with 300-mg once-daily oral dosing. This phase 1 study investigated the pharmacokinetics and safety/tolerability of multiple oral omadacycline doses higher than 300 mg. Using a 3-period crossover design, healthy adults were randomized to receive oral omadacycline at 300, 450, and 600 mg in variable sequence (n = 26) or placebo (n = 7) once daily for 5 consecutive days per period. In plasma, omadacycline maximum concentration and total exposure increased with increasing dose but were less than dose proportional. The kinetics of omadacycline plasma accumulation were similar between dose levels; exposure on day 5 was ~50% higher than that on day 1. Omadacycline plasma concentrations on day 1 of 450-mg dosing were similar to those on day 5 of 300-mg dosing. All doses were generally well tolerated, but the 600-mg dose was associated with more gastrointestinal adverse events. PMID- 29180525 TI - Increasing Antimicrobial Resistance in Nontyphoidal Salmonella Isolates in Australia from 1979 to 2015. AB - Australia has high and increasing rates of salmonellosis. To date, the serovar distribution and associated antimicrobial resistance (AMR) patterns of nontyphoidal Salmonella enterica (NTS) in Australia have not been assessed. Such information provides critical knowledge about AMR in the food chain and informs decisions about public health. We reviewed longitudinal data on NTS in two Australian states over a 37-year period, between 1979 and 2015, and antimicrobial resistance since 1984. Overall, 17% of isolates were nonsusceptible to at least one antimicrobial, 4.9% were nonsusceptible to ciprofloxacin, and 0.6% were nonsusceptible to cefotaxime. In total, 2.5% of isolates were from invasive infections, with no significant difference in AMR profiles between invasive and noninvasive isolates. Most isolates with clinically relevant AMR profiles were associated with travel, particularly to Southeast Asia, with multiple "incursions" of virulent and resistant clones into Australia. Our findings represent the largest longitudinal surveillance system for NTS in Australia and provide valuable public health knowledge on the trends and distribution of AMR in NTS. Ongoing surveillance is critical to identify local emergence of resistant isolates. PMID- 29180526 TI - Antibacterial and Sterilizing Effect of Benzylpenicillin in Tuberculosis. AB - The modern chemotherapy era started with Fleming's discovery of benzylpenicillin. He demonstrated that benzylpenicillin did not kill Mycobacterium tuberculosis In this study, we found that >64 mg/liter of static benzylpenicillin concentrations killed 1.16 to 1.43 log10 CFU/ml below starting inoculum of extracellular and intracellular M. tuberculosis over 7 days. When we added the beta-lactamase inhibitor avibactam, benzylpenicillin maximal kill (Emax) of extracellular log phase-growth M. tuberculosis was 6.80 +/- 0.45 log10 CFU/ml at a 50% effective concentration (EC50) of 15.11 +/- 2.31 mg/liter, while for intracellular M. tuberculosis it was 2.42 +/- 0.14 log10 CFU/ml at an EC50 of 6.70 +/- 0.56 mg/liter. The median penicillin (plus avibactam) MIC against South African clinical M. tuberculosis strains (80% either multidrug or extensively drug resistant) was 2 mg/liter. We mimicked human-like benzylpenicillin and avibactam concentration-time profiles in the hollow-fiber model of tuberculosis (HFS-TB). The percent time above the MIC was linked to effect, with an optimal exposure of >=65%. At optimal exposure in the HFS-TB, the bactericidal activity in log-phase growth M. tuberculosis was 1.44 log10 CFU/ml/day, while 3.28 log10 CFU/ml of intracellular M. tuberculosis was killed over 3 weeks. In an 8-week HFS-TB study of nonreplicating persistent M. tuberculosis, penicillin-avibactam alone and the drug combination of isoniazid, rifampin, and pyrazinamide both killed >7.0 log10 CFU/ml. Monte Carlo simulations of 10,000 preterm infants with disseminated disease identified an optimal dose of 10,000 U/kg (of body weight)/h, while for pregnant women or nonpregnant adults with pulmonary tuberculosis the optimal dose was 25,000 U/kg/h, by continuous intravenous infusion. Penicillin-avibactam should be examined for effect in pregnant women and infants with drug-resistant tuberculosis, to replace injectable ototoxic and teratogenic second-line drugs.

AB - The pharmacodynamic profile of azithromycin against persistent strains of nontypeable Haemophilus influenzae (NTHi) from chronic obstructive pulmonary disease (COPD) patients was characterized. Azithromycin displayed differential concentration-dependent activities (R2 >= 0.988); the pharmacodynamic response was attenuated when we compared the "first" and "last" strains of NTHi that persisted in the airways of the same patient for 819 days (the 50% effective concentration [EC50] increased more than 50 times [0.0821 mg/liter versus 4.23 mg/liter]). In the hollow-fiber infection model, NTHi viability was maintained throughout simulated azithromycin (Zithromax) Z-Pak regimens over 10 days. PMID- 29180528 TI - Simple In Vitro Assay To Evaluate the Incorporation Efficiency of Ribonucleotide Analog 5'-Triphosphates into RNA by Human Mitochondrial DNA-Dependent RNA Polymerase. AB - There is a growing body of evidence suggesting that some ribonucleoside/ribonucleotide analogs may be incorporated into mitochondrial RNA by human mitochondrial DNA-dependent RNA polymerase (POLRMT) and disrupt mitochondrial RNA synthesis. An assessment of the incorporation efficiency of a ribonucleotide analog 5'-triphosphate by POLRMT may be used to evaluate the potential mitochondrial toxicity of the analog early in the development process. In this report, we provide a simple method to prepare active recombinant POLRMT. A robust in vitro nonradioactive primer extension assay was developed to assay the incorporation efficiency of ribonucleotide analog 5'-triphosphates. Our results show that many ribonucleotide analogs, including some antiviral compounds currently in various preclinical or clinical development stages, can be incorporated into newly synthesized RNA by POLRMT and that the incorporation of some of them can lead to chain termination. The discrimination (D) values of ribonucleotide analog 5'-triphosphates over those of natural ribonucleotide triphosphates (rNTPs) were measured to evaluate the incorporation efficiency of the ribonucleotide analog 5'-triphosphates by POLRMT. The discrimination values of natural rNTPs under the condition of misincorporation by POLRMT were used as a reference to evaluate the potential mitochondrial toxicity of ribonucleotide analogs. We propose the following criteria for the potential mitochondrial toxicity of ribonucleotide analogs based on D values: a safe compound has a D value of >105; a potentially toxic compound has a D value of >104 but <105; and a toxic compound has a D value of <104 This report provides a simple screening method that should assist investigators in designing ribonucleoside-based drugs having lower mitochondrial toxicity.

PMID- 29180529 TI - The ABC of Biofilm Drug Tolerance: the MerR-Like Regulator BrlR Is an Activator of ABC Transport Systems, with PA1874-77 Contributing to the Tolerance of Pseudomonas aeruginosa Biofilms to Tobramycin. AB - A hallmark of biofilms is their tolerance to killing by antimicrobial agents. In Pseudomonas aeruginosa, biofilm drug tolerance requires the c-di-GMP-responsive MerR transcriptional regulator BrlR. However, the mechanism by which BrlR mediates biofilm drug tolerance has not been elucidated. Here, we demonstrate that BrlR activates the expression of at least 7 ABC transport systems, including the PA1874-PA1875-PA1876-PA1877 (PA1874-77) operon, with chromatin immunoprecipitation and DNA binding assays confirming BrlR binding to the promoter region of PA1874-77. Insertional inactivation of the 7 ABC transport systems rendered P. aeruginosa PAO1 biofilms susceptible to tobramycin or norfloxacin. Susceptibility was linked to drug accumulation, with BrlR contributing to norfloxacin accumulation in a manner dependent on multidrug efflux pumps and the PA1874-77 ABC transport system. Inactivation of the respective ABC transport system, furthermore, eliminated the recalcitrance of biofilms to killing by tobramycin but not norfloxacin, indicating that drug accumulation is not linked to biofilm drug tolerance. Our findings indicate for the first time that BrlR, a MerR-type transcriptional activator, activates genes encoding several ABC transport systems, in addition to multiple multidrug efflux pump genes. Moreover, our data confirm a BrlR target contributing to drug tolerance, likely countering the prevailing dogma that biofilm tolerance arises from a multiplicity of factors. PMID- 29180531 TI - Anion Gap as a Determinant of Ionized Fraction of Divalent Cations in Hemodialysis Patients. AB - BACKGROUND AND OBJECTIVES: Circulating levels of anions that bind to magnesium and calcium are often altered in patients with CKD. However, it is unknown how these alterations affect the ionized fraction of magnesium and calcium. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This cross-sectional study involved patients on maintenance hemodialysis and patients not on dialysis who visited the outpatient department of nephrology. We collected whole-blood samples to measure ionized magnesium and calcium concentrations. Adjusted anion gap was calculated as an integrative index of unmeasured anions. RESULTS: A total of 118 patients on hemodialysis and 112 patients not on dialysis were included. Although the prevalence of hypermagnesemia defined by total magnesium was much higher in patients on hemodialysis than in patients not on dialysis (69% versus 12%; P<0.001), the prevalence of hypermagnesemia defined by ionized magnesium did not differ significantly (13% versus 18%; P=0.28). Among patients on hemodialysis with high total magnesium, 83% had normal or low ionized magnesium. Consequently, the mean ionized fraction of magnesium in patients on hemodialysis was significantly lower than that in patients not on dialysis (51% versus 63%; P<0.001). Similarly, the mean ionized fraction of calcium in patients on hemodialysis was lower than that in patients not on dialysis (55% versus 56%; P<0.001). In patients on hemodialysis who had a higher adjusted anion gap than patients not on dialysis (mean [SD]: 14.1 [2.2] versus 5.1 [3.1]), the ionized fractions of magnesium and calcium were inversely associated with the adjusted anion gap. Furthermore, the anion gap significantly improved predictions of ionized magnesium and calcium in patients on hemodialysis. CONCLUSIONS: Anions that accumulate in patients on hemodialysis contribute to the lower ionized fraction of magnesium and calcium. Equations that incorporate the anion gap provide better predictions of ionized magnesium and calcium in patients on hemodialysis.

AB - OBJECTIVE: To obtain insight into tobacco retailing by alcohol-licenced premises, in order to understand the financial importance of tobacco sales for such retailers. METHOD: Data were collected by a telephone survey of 1042 clubs, hotels and packaged liquor outlets in New South Wales, Australia. The response rate was 86.1%. Qualitative and quantitative data were obtained. Logistic and linear regression were used to determine factors associated with the probability of selling and stopping selling and the importance of cigarette sales. RESULTS: More than a third (36.4%) of premises contacted did not sell cigarettes. 147 (an estimated 18.1% of those who had ever sold) had stopped selling. There were significant differences in the probability of selling, in the reported importance of cigarette sales and in the probability of stopping selling, between different outlet types and other outlet characteristics (number of gaming machines, proximity of nearest alternative tobacco retailer and remoteness). Outlets where alcohol can be consumed were more likely to rate cigarette sales as 'not important' than 'important'. CONCLUSIONS: Despite claims by tobacco companies that tobacco sales are important for many Australian retailers, tobacco sales appear to be of limited importance for alcohol-licenced premises. This means that opposition to stopping tobacco sales where alcohol is consumed and/or sold may be less than expected.

AB - BACKGROUND: In the 1990s, California led the USA in state-level tobacco control strategies. However, after 2000, California lost ground on cigarette taxes, although it maintained higher levels of smoke-free homes among smokers. METHODS: Trends in per capita cigarette consumption were assessed through taxed sales data and from self-report in repeated national cross-sectional surveys. Linear regressions identified changes in trends after year 2000 separately for California and the rest of the USA. Using data from each state, a linear regression tested the association between different tobacco control strategies and per capita consumption. Change in self-reported per capita consumption was partitioned into contributions associated with initiation, quitting and reduction in cigarette consumption level. RESULTS: Both taxed cigarette sales and per capita consumption declined rapidly in the USA from 1985 to 2015. Declines were particularly fast in California before 2000 but slowed thereafter. In 2014, per capita consumption in California was 29.4 packs/adult/year, but 90% higher in the rest of the USA. Modelling state-level data, every $1 increase in cigarette taxes reduced consumption by 4.8 (95% CI 2.9 to 6.8) packs/adult/year. Every 5% increase in the proportion of smokers with smoke-free homes reduced consumption by 8.0 (95% CI 7.0 to 8.9) packs/adult/year. The different patterns in California and the rest of the USA are at least partially explained by these two variables. The slow down in per capita consumption in California can be attributed to changes in initiation, quitting and especially smokers reducing their consumption level. CONCLUSIONS: Tobacco control strategies need to be continually updated to maintain momentum towards a smoke-free society. PMID- 29180535 TI - Radiotherapy and CTLA-4 Blockade Shape the TCR Repertoire of Tumor-Infiltrating T Cells. AB - Immune checkpoint inhibitors activate T cells to reject tumors. Unique tumor mutations are key T-cell targets, but a comprehensive understanding of the nature of a successful antitumor T-cell response is lacking. To investigate the T-cell receptor (TCR) repertoire associated with treatment success versus failure, we used a well-characterized mouse carcinoma that is rejected by CD8 T cells in mice treated with radiotherapy (RT) and anti-CTLA-4 in combination, but not as monotherapy, and comprehensively analyzed tumor-infiltrating lymphocytes (TILs) by high-throughput sequencing of the TCRBeta CDR3 region. The combined treatment increased TIL density and CD8/CD4 ratio. Assessment of the frequency of T-cell clones indicated that anti-CTLA-4 resulted in fewer clones and a more oligoclonal repertoire compared with untreated tumors. In contrast, RT increased the CD8/CD4 ratio and broadened the TCR repertoire, and when used in combination with anti CTLA-4, these selected T-cell clones proliferated. Hierarchical clustering of CDR3 sequences showed a treatment-specific clustering of TCRs that were shared by different mice. Abundant clonotypes were commonly shared between animals and yet treatment-specific. Analysis of amino-acid sequence similarities revealed a significant increase in the number and richness of dominant CDR3 motifs in tumors treated with RT + anti-CTLA-4 compared with control. The repertoire of TCRs reactive with a single tumor antigen recognized by CD8+ T cells was heterogeneous but highly clonal, irrespective of treatment. Overall, data support a model whereby a diverse TCR repertoire is required to achieve tumor rejection and may underlie the synergy between RT and CTLA-4 blockade. Cancer Immunol Res; 6(2); 139-50.

AB - The GD2 ganglioside, which is abundant on the surface of neuroblastoma cells, is targeted by an FDA-approved therapeutic monoclonal antibody and is an attractive tumor-associated antigen for cellular immunotherapy. Chimeric antigen receptor (CAR)-modified T cells can have potent antitumor activity in B-cell malignancies, and trials to harness this cytolytic activity toward GD2 in neuroblastoma are under way. In an effort to enhance the antitumor activity of CAR T cells that target GD2, we generated variant CAR constructs predicted to improve the stability and the affinity of the GD2-binding, 14G2a-based, single-chain variable fragment (scFv) of the CAR and compared their properties in vivo We included the E101K mutation of GD2 scFv (GD2-E101K) that has enhanced antitumor activity against a GD2+ human neuroblastoma xenograft in vivo However, this enhanced antitumor efficacy in vivo was concomitantly associated with lethal central nervous system (CNS) toxicity comprised of extensive CAR T-cell infiltration and proliferation within the brain and neuronal destruction. The encephalitis was localized to the cerebellum and basal regions of the brain that display low amounts of GD2. Our results highlight the challenges associated with target antigens that exhibit shared expression on critical normal tissues. Despite the success of GD2-specific antibody therapies in the treatment of neuroblastoma, the fatal neurotoxicity of GD2-specific CAR T-cell therapy observed in our studies suggests that GD2 may be a difficult target antigen for CAR T-cell therapy without additional strategies that can control CAR T-cell function within the CNS.

PMID- 29180537 TI - A cross-sectional study examining associations between substance use frequency, problematic use and STIs among youth living with HIV. AB - OBJECTIVES: This study sought to examine the prevalence of STIs and whether substance use frequency and/or problematic use-specifically alcohol, marijuana and other drugs-was associated with having an STI diagnosis among youth living with HIV (YLWH) METHODS: A sample of 823 YLWH were recruited at 14 adolescent HIV clinics through the Adolescent Medicine Trials Network for HIV Interventions. Study staff abstracted STI data from medical records for up to 26 weeks prior to participants' completing a cross-sectional survey including the ASSIST (Alcohol, Smoking and Substance Involvement Screening Test), which measures substance use frequency and consequences. RESULTS: Almost one-third of youth had been diagnosed with an STI (30.5%) at the time of their baseline assessment. In multivariable analyses, those who engaged in weekly or greater marijuana use (adjusted OR (AOR)=10.66, 95% CI: 4.39 to 25.87, P<0.001) had an increased odds of being diagnosed with an STI. Additionally, youth who met alcohol use criteria for moderate (AOR=5.23, 95% CI: 2.50 to 10.93, P<0.001) and high risk (AOR=6.53, 95% CI: 1.20 to 35.68, P<0.05) alcohol use had an increased odds of being diagnosed with an STI compared with low-risk alcohol users. CONCLUSIONS: Study findings underscore the need to investigate the role of greater frequency of marijuana use and problematic alcohol use in STI incidence among YLWH. Given the associations between both substance use frequency and problematic use in STI diagnoses among YLWH seen in HIV care settings, clinicians should use validated substance use screening tools which capture both frequencies and consequences in order to identify YLWH who may need further evaluation and treatment.

PMID- 29180538 TI - Prevalence and sociodemographic correlates of cervicovaginal human papillomavirus (HPV) carriage in a cross-sectional, multiethnic, community-based female Asian population. AB - OBJECTIVES: Cervical cancer is a largely preventable disease, and the strategic implementation of a cervical cancer prevention programme is partly dependent on the impact of human papillomavirus (HPV) infection interpreted within the context of the country's sociodemographic attributes. The objective of this study is to determine the prevalence of cervicovaginal HPV infection among a healthy, community-based, multiethnic Malaysian population. The HPV prevalence was subsequently correlated to the individual's sociodemographics and sexual/reproductive history. Of significance, the observed prevalence captured was in a birth cohort not included in the national school-based HPV vaccination programme. METHODS: This was a cross-sectional study where 1293 healthy women aged between 18 and 60 years were recruited via convenience sampling from five community-based clinics in Selangor, Malaysia. Cervicovaginal self-samples were obtained and DNA was extracted for HPV detection and genotyping. A comprehensive questionnaire was administered to determine the sociodemographics and behavioural patterns of participants. RESULTS: The median age at enrolment was 37 years old (IQR: 30-47). In total, 86/1190 (7.2%) of the samples collected were positive for HPV infection, with the highest HPV prevalence (11.9%) detected in the subgroup of 18-24 years old. The top three most prevalent HPV genotypes were HPV 16, 52 and 58. The independent risk factors associated with higher rates of HPV infection included Indian ethnicity, widowed status and women with partners who are away from home for long periods and/or has another sexual partner. CONCLUSIONS: The overall prevalence of HPV infection in this Malaysian multiethnic population was 7.2%, with 6.5% being high-risk genotypes. The top three most common high-risk HPV types were HPV 16, 52 and 58. This information is important for the planning of primary (HPV vaccination) and secondary (screening) cervical cancer prevention programmes in Malaysia. PMID- 29180540 TI - Reducing alarms in the NICU. PMID- 29180541 TI - Neonatal brain injuries in England: population-based incidence derived from routinely recorded clinical data held in the National Neonatal Research Database. AB - OBJECTIVE: In 2015, the Department of Health in England announced an ambition to reduce 'brain injuries occurring during or soon after birth'. We describe the development of a pragmatic case definition and present annual incidence rates. DESIGN: Retrospective cohort study using data held in the National Neonatal Research Database (NNRD) extracted from neonatal electronic patient records from all National Health Service (NHS) neonatal units in England, Wales and Scotland. In 2010-2011, population coverage in the NNRD was incomplete, hence rate estimates are presented as a range; from 2012, population coverage is complete, and rates (95% CIs) are presented. Rates are per 1000 live births. SETTING: NHS neonatal units in England. PATIENTS: Infants admitted for neonatal care; denominator: live births in England. MAIN OUTCOME MEASURE: 'Brain injuries occurring at or soon after birth' defined as infants with seizures, hypoxic ischaemic encephalopathy, stroke, intracranial haemorrhage, central nervous system infection and kernicterus and preterm infants with cystic periventricular leucomalacia. RESULTS: In 2010, the lower estimate of the rate of 'Brain injuries occurring at or soon after birth' in England was 4.53 and the upper estimate was 5.19; in 2015, the rate was 5.14 (4.97, 5.32). For preterm infants, the population incidence in 2015 was 25.88 (24.51, 27.33) and 3.47 (3.33, 3.62) for term infants. Hypoxic-ischaemic encephalopathy was the largest contributor to term brain injury, and intraventricular/periventricular haemorrhage was the largest contributor to preterm brain injury. CONCLUSIONS: Annual incidence rates for brain injuries can be estimated from data held in the NNRD; rates for individual conditions are consistent with published rates. Routinely recorded clinical data can be used for national surveillance, offering efficiencies over traditional approaches. PMID- 29180542 TI - Myocardial revascularisation in high-risk subjects. PMID- 29180543 TI - Multiple Practical Facts and Ideas to Improve Family Medicine Care. AB - Seconds count in a study on the best electronic health note format to reduce medical record charting time and increase accuracy. Directly observed family physician work is compared with Current Procedural Terminology (CPT) coding examples and notably under-recognized. This issue contains articles from single practices that that implemented new methods of care and other reports on practice innovations that can be more broadly implemented. We have articles on opioid medication use for acute low back pain in primary care, an electronic chronic pain consult service, a key question to identify potential opioid misuse risk, and newly implemented screening for other substances of abuse. Omissions (or gaps) in care are also highlighted: from the common types of omissions identified by primary care clinicians, self-reported low levels of substance use screening by family medicine prenatal care providers, and inadequate and inadequately available hospital discharge summaries. In addition, the most important alarm symptoms for a cancer diagnosis are reported. PMID- 29180544 TI - Dynamic Electronic Health Record Note Prototype: Seeing More by Showing Less. AB - INTRODUCTION: Cluttered documentation may contribute adversely to physician readers' cognitive load, inadvertently obscuring high-value information with less valuable information. We test the hypothesis that a novel, collapsible assessment, plan, subjective, objective (APSO) note design would be faster, more accurate, and more satisfying to use than a conventional electronic health record (EHR) subjective, objective, assessment, plan (SOAP) note for finding information needed for ambulatory chronic disease care. METHODS: We iteratively developed physician clinic note prototypes with features designed to emphasize more important information and de-emphasize less clinically relevant information. Sixteen primary care physicians reviewed comparable clinic notes with the 4 note styles presented in random order to find key information in the notes during timed tasks. The 4 note styles were denoted A (traditional SOAP note), B (2 column APSO note), C (collapsible APSO note), and D (2-column collapsible APSO note). The 4 unique note styles were designed to have equal amounts of information in each section. We simulated their utility for clinical practice by imposing time limits and by interrupting 1 of the tasks with a typical clinical interruption. For each session, we recorded audio, computer-screen activity, eye tracking, and made field notes. We obtained usability ratings (System Usability Scale), new feature preference ratings, and performed semistructured post-task interviews with subsequent content analysis. We compared the effectiveness of the 4 note styles by measuring time on task, task success (accuracy), and effort as measured by NASA Task Load Index. RESULTS: Note styles C and D were significantly faster than A and B for the Review of Systems and Physical Examination tasks, as we expected. Notes B and C had the best success (finding requested data) scores. Users strongly endorsed all the new note features incorporated into the new note prototypes. Previously expressed concerns about temporarily hiding parts of the note (using the accordion display design pattern) were allayed. Usability ratings for note A were worst but comparably better for note styles B, C, and D. DISCUSSION: The new APSO note prototypes performed better than the traditional SOAP note format for speed, task success (accuracy), and usability for physician users acquiring information needed for a typical chronic disease visit in primary care. Moving Assessment and Plan to the top is 1 easily accomplished feature change. Innovative documentation displays of EHR data can safely improve information display without eliminating data from the record of the visit. PMID- 29180545 TI - Implementation of a Standardized Medication Therapy Management Plus Approach within Primary Care. AB - PURPOSE: The purpose of this study was to implement a clinical pharmacist-led medication therapy management (MTM) service within a primary-care setting that is enhanced by 1) a clinical decision support system (CDSS) that includes a unique combination of medication risk mitigation factors, which aids the pharmacist in interpreting the medication profile, and 2) pharmacogenomics (PGx) testing. METHODS: This was a service implementation study, whereby Medicare beneficiaries were eligible if they were patients of Elmwood Family Physicians, a private family, primary care practice with 2 locations in New Jersey, and were on at least 7 medications. Patients had a medication reconciliation completed by a pharmacist and performed a PGx buccal swab. Patient information was run through a CDSS to aid the pharmacist with screening for multidrug interactions and assessing patient's medication-related risks. The output of the CDSS was used to create recommendations and provide a consult to the physicians. Recommendations were followed up by return of the consult. RESULTS: Enrolled patients used a mean (+/- standard deviation) of 12.1 (+/- 4.6) medications. The turnaround time for the MTM Plus consults was 11.7 (+/- 6.2) days. During the consults, the pharmacist identified 138 medication-related problems (MRPs). The most common MRPs were drug-drug interactions (29.0%) and drug-gene interactions (DGIs; 24.6%). CONCLUSION: Implementing a clinical pharmacist-led MTM Plus service in the primary care setting is feasible. This study highlights that DGIs are common in older adults in family practice and indicates that PGx testing identifies additional MRPs that may otherwise go unnoticed in these patients. The experiences we shared can aid other clinicians in establishing successful MTM Plus services. Future studies should also measure the impact of such personalized medicine services on economic, clinical, and humanistic outcomes. This study has been registered with ClinicalTrials.gov (study No. NCT02748148). PMID- 29180546 TI - Impact of a Novel Wellness Group Visit Model on Obesity and Behavior Change. AB - BACKGROUND: Increasing weight-related illness in the United States has led to 120,000 preventable deaths annually and soaring medical costs. Treating patients in a group setting may be more effective than traditional care (TC) in achieving behavioral change. We studied a wellness-group (WG) model to determine whether it could generate sustained behavioral change and weight loss in a subset of patients. METHODS: 99 patients with a body mass index (BMI) >30 kg/m2 from 1 family practice volunteered to participate in a 15-visit WG co-led by a family physician and dietitian. We compared these WG patients with 190 patients who had a BMI >30 kg/m2 and who received TC in the form of an annual physical during the same time period. The patients were mostly white, highly educated, and of middle to-high-income households. All patients were surveyed on their ability to sustain 12 wellness behaviors 3 months after completing their WG or physical. Patients were not paid to complete the survey. We reviewed medical charts for weight, BMI, blood pressure, lipids, and glycohemoglobin before and at least 1 year after the WG or physical. WG patients' weights were recorded at the beginning and end of the WG as was the weight from their most recent office visit. RESULTS: WG patients were more likely to report sustaining 12 of 12 wellness behaviors than patients who received TC with an annual physical. At 1 year, WG patients also lost more weight than TC patients (-13.21 pounds for WG vs +1.94 pounds for TC) and achieved greater reduction in their systolic blood pressure (-6.96 mm Hg for WG vs -1.13 mm Hg for TC). Average weight gained after the WG was 6.9 pounds. Among WG patients, 61% lost a clinically relevant amount of weight (>5%). Of the WG patients who lost clinically relevant weight, 71% were able to maintain at least half of their weight loss 3 years later. CONCLUSIONS: An observational study of a novel WG model showed that WG patients sustained wellness behaviors and weight loss over time when compared with patients who received TC. PMID- 29180547 TI - The Full Scope of Family Physicians' Work Is Not Reflected by Current Procedural Terminology Codes. AB - BACKGROUND: The purpose of this study was to characterize the content of family physician (FP) clinic encounters, and to count the number of visits in which the FPs addressed issues not explicitly reportable by 99211 to 99215 and 99354 Current Procedural Terminology (CPT) codes with current reimbursement methods and based on examples provided in the CPT manual. METHODS: The data collection instrument was modeled on the National Ambulatory Medical Care Survey. Trained assistants directly observed every other FP-patient encounter and recorded every patient concern, issue addressed by the physician (including care barriers related to health care systems and social determinants), and treatment ordered in clinics affiliated with 10 residencies of the Residency Research Network of Texas. A visit was deemed to include physician work that was not explicitly reportable if the number or nature of issues addressed exceeded the definitions or examples for 99205/99215 or 99214 + 99354 or a preventive service code, included the physician addressing health care system or social determinant issues, or included the care of a family member. RESULTS: In 982 physician patient encounters, patients raised 517 different reasons for visit (total, 5278; mean, 5.4 per visit; range, 1 to 16) and the FPs addressed 509 different issues (total issues, 3587; mean, 3.7 per visit; range, 1 to 10). FPs managed 425 different medications, 18 supplements, and 11 devices. A mean of 3.9 chronic medications were continued per visit (range, 0 to 21) and 4.6 total medications were managed (range, 0 to 22). In 592 (60.3%) of the visits the FPs did work that was not explicitly reportable with available CPT codes: 582 (59.3%) addressed more numerous issues than explicitly reportable, 64 (6.5%) addressed system barriers, and 13 (1.3%) addressed concerns for other family members. CONCLUSIONS AND RELEVANCE: FPs perform cognitive work in a majority of their patient encounters that are not explicitly reportable, either by being higher than the CPT example number of diagnoses per code or the type of problems addressed, which has implications for the care of complex multi-morbid patients and the growth of the primary care workforce. To address these limitations, either the CPT codes and their associated rules should be updated to reflect the realities of family physicians' practices or new billing and coding approaches should be developed. PMID- 29180548 TI - Primary Care Providers' Perspectives on Errors of Omission. AB - BACKGROUND: Despite recent focus on patient safety in primary care, little attention has been paid to errors of omission, which represent significant gaps in care and threaten patient safety in primary care but are not well studied or categorized. The purpose of this study was to develop a typology of errors of omission from the perspectives of primary care providers (PCPs) and understand what factors within practices lead to or prevent these omissions. METHODS: A qualitative descriptive design was used to collect data from 26 PCPs, both physicians and nurse practitioners, from the New York State through individual interviews. One researcher conducted all interviews, which were audiotaped, transcribed verbatim, and analyzed in ATLAS.ti, Berlin by 3 researchers using content analysis. They immersed themselves into data, read transcripts independently, and conducted inductive coding. The final codes were linked to each other to develop the typology of errors of omission and the themes. Data saturation was reached at the 26th interview. RESULTS: PCPs reported that omitting patient teaching, patient followup, emotional support, and addressing mental health needs were the main categories of errors of omission. PCPs perceived that time constraints, unplanned patient visits and emergencies, and administrative burden led to these gaps in care. They emphasized that organizational support and infrastructure, effective teamwork and communication, and preparation for the patient encounter were important safeguards to prevent errors of omission within their practices. DISCUSSION: Errors of omission are common in primary care and could threaten patient safety. Efforts to eliminate them should focus on strengthening organizational attributes of practices, improving teamwork and communication, and assigning manageable workload to PCPs. CONCLUSIONS: Practice and policy change is necessary to address gaps in care and prevent them before they result in patient harm. PMID- 29180549 TI - Family Physicians' Perceived Prevalence, Safety, and Screening for Cigarettes, Marijuana, and Electronic-Nicotine Delivery Systems (ENDS) Use during Pregnancy. AB - OBJECTIVE: Assess perceptions of prevalence, safety, and screening practices for cigarettes and secondhand smoke exposure (SHSe), marijuana (and synthetic marijuana), electronic nicotine delivery systems (ENDS; eg, e-cigarettes), nicotine-replacement therapy (NRT), and smoking-cessation medications during pregnancy, among primary care physicians (PCPs) providing obstetric care. METHODS: A web-based, cross-sectional survey was e-mailed to 3750 US physicians (belonging to organizations within the Council of Academic Family Medicine Educational Research Alliance). Several research groups' questions were included in the survey. Only physicians who reported providing "labor and delivery" obstetric care responded to questions related to the study objectives. RESULTS: A total of 1248 physicians (of 3750) responded (33.3%) and 417 reported providing labor and delivery obstetric care. Obstetric providers (N = 417) reported cigarette (54%), marijuana (49%), and ENDS use (24%) by "Some (6% to 25%)" pregnant women, with 37% endorsing that "Very Few (1% to 5%)" pregnant women used ENDS. Providers most often selected that very few pregnant women used NRT (45%), cessation medications (ie, bupropion or varenicline; 37%), and synthetic marijuana (23%). Significant proportions chose "Do not Know" for synthetic marijuana (58%) and ENDS (27%). Over 90% of the sample perceived that use of or exposure to cigarettes (99%), synthetic marijuana (99%), SHS (97%), marijuana (92%), or ENDS (91%) were unsafe during pregnancy, with the exception of NRT (44%). Providers most consistently screened for cigarette (85%) and marijuana use (63%), followed by SHSe in the home (48%), and ENDS (33%) and synthetic marijuana use (28%). Fewer than a quarter (18%) screened consistently for all substances and SHSe. One third (32%) reported laboratory testing for marijuana and 3% reported laboratory testing for smoking status. CONCLUSION: This sample of PCPs providing obstetric care within academic settings perceived cigarettes, marijuana, and ENDS use to be prevalent and unsafe during pregnancy. Opportunities for increased screening during pregnancy across these substances were apparent. PMID- 29180550 TI - Information Transfer and the Hospital Discharge Summary: National Primary Care Provider Perspectives of Challenges and Opportunities. AB - PURPOSE: The hospital discharge summary (HDS) serves as a critical method of patient information transfer between hospitalist and primary care provider (PCP). This study was designed to increase our understanding of PCP preferences for, and perceived deficiencies in, the discharge summary. METHODS: We designed a mail survey that was sent to a random sample of 800 American Academy of Family Physicians members nationally. The survey response rate was 59%. We analyzed the availability of summaries at hospital followup, whether all desired information was contained in the summary and whether certain specific items were completed. Provider subgroup analysis was performed. RESULTS: The strongest predictor of discharge summary availability at posthospital followup is direct access to inpatient data. Respondents (27.5%) had a summary available 0% to 40% of the time, 41.4% noted availability 41% to 80% of the time and 31.1% >80% of the time; if a provider had access to inpatient data they tended to have a discharge summary available to them (P < .0001). Providers also described significant content deficits: 26.5% of providers noted the summary contained all information needed 0% to 40% of the time, 48.5% of providers noted this 41% to 80% of the time and only 25% >80% of the time. Specific summary items considered "very important" by providers included medication list (94% of respondents), diagnosis list (89%), and treatment provided (87%). CONCLUSIONS: Opportunities remain in timely delivery of a complete HDS to the PCP. Further multifaceted practice redesign should be directed at optimizing this critical information transfer tool, potentially encompassing electronic medical record utilization and specific training for clinicians preparing summaries. Initial efforts should focus on ensuring availability of a complete summary (containing items deemed important by PCPs including medication list, diagnosis list, and treatment provided) at the posthospital follow-up visit. PMID- 29180551 TI - Supporting Better Access to Chronic Pain Specialists: The Champlain BASETM eConsult Service. AB - INTRODUCTION: Excessive wait times for chronic pain are associated with significant reductions in quality of life and worse health outcomes. The Champlain BASETM (Building Access to Specialists through eConsultation) eConsult service can improve access to specialist care for patients with chronic pain by facilitating electronic communication between primary care providers (PCPs) and specialists. We explored the content of eConsult cases sent to chronic pain specialists to identify the major themes emerging from exchanges between PCPs and specialists regarding patients with chronic pain. METHODS: We conducted a thematic analysis of eConsult cases submitted to chronic pain specialists between April 1, 2011 and October 31, 2014, using a constant comparison approach. RESULTS: PCPs submitted 128 cases to chronic pain specialists during the study period. The study team coded 48 cases before data saturation was reached. PCPs sought advice for treating patients with chronic pain arising from a range of medical problems, and who frequently struggled with issues of mental health, substance dependence, and social complexity. Specialists responded with advice on pain management and treatment, directed PCPs to published guidelines and community resources, and validated the PCPs' frustration or concerns. Specialists provided instruction on safe opioid prescribing and how to identify and manage potential cases of substance dependence. CONCLUSION: Providing care to patients with chronic pain is a challenge for PCPs, who often experience frustration at their inability to provide a definitive solution for patients. Specialists offered invaluable feedback not only through guidance and advice, but also with sympathy and encouragement. PMID- 29180552 TI - Neighborhood Socioeconomic Status and Receipt of Opioid Medication for New Back Pain Diagnosis. AB - BACKGROUND: Although treatment for new back pain is heavily guideline driven, deviations occur frequently. Neighborhood socioeconomic status (nSES) may contribute to these deviations. OBJECTIVE: Determine whether nSES is associated with type of treatment provided for patients seeking treatment for new back pain in primary care clinics. METHODS: This retrospective cohort was conducted in academic internal and family medicine practices. Data were examined from the Primary Care Patient Data Registry. Eligibility criteria included age >=18 years, free of HIV and cancer, and presenting to primary care with a new diagnosis of back pain, resulting in1646 patients included. Patients' nSES was determined using ZIP code and calculating a validated index of 7 census-tract variables. Multinomial logistic regression was used to measure the association between nSES and 3 treatment outcomes compared with no pharmacologic management. Outcomes included opioid prescription, nonsteroidal anti-inflammatory (NSAID)/muscle relaxant prescription, or combined opioid/nonopioid treatment within 90 days of initial presentation. Covariates included age, sex, race, high clinic utilization (HCU), depression, anxiety, substance use, obesity, comorbidities, smoking, number of pain conditions, and physical therapy (PT) referral. RESULTS: The cohort was 67.9% female with an average age of 55.72 years (Standard Error [SE] = 0.387). Compared with no pharmacologic treatment, individuals in the low nSES group had 63% higher odds of receiving an opioid only compared with the high nSES group (odds ratio [OR], 1.63; 95% confidence interval [CI], 1.01 to 2.62). There was no significant association between nSES and odds of nonopioid or combined treatment compared with no pharmacotherapy (OR, 1.17; 95% CI, 0.97 to 1.50), (OR, 1.09; 95% CI, 0.67 to 1.78), respectively. Covariates associated with increased odds of opioid only included HCU, ever smoker, and increasing comorbidity index. PT referral was associated with NSAID/muscle relaxant only, and increasing age and comorbidity index were inversely associated with odds of NSAID/muscle relaxant only. Finally, covariates associated with increased odds of receiving both therapies included high clinic utilizusation, ever smoking, and PT referral. CONCLUSIONS: These data characterize a possible association between low nSES and increased risk of receiving an opioid only when being treated for new back pain. This may be evidence that patients of low nSES are at increased risk of receiving guideline-noncompliant treatment for new back pain. PMID- 29180553 TI - Relationship of Opioid Prescriptions to Physical Therapy Referral and Participation for Medicaid Patients with New-Onset Low Back Pain. AB - INTRODUCTION: Physical therapy (PT) early in the management of low back pain (LBP) is associated with reductions in subsequent health care utilization and LBP related costs. The objectives of this study were to 1) Examine differences among newly consulting patients with LBP who received a PT referral and those who did not, 2) examine differences between patients who participated in PT to those who did not, and 3) compare the impact of a PT referral and PT participation on LBP related health care utilization and costs over 1 year. METHODS: This was a retrospective cohort study using electronic medical records and claims data. Participants were 454 Medicaid enrollees with new LBP consultations (mean age, 40.4 years; SD = 12.0; 70% women). Outcomes included advanced imaging, injections, emergency department visits, opioid prescriptions, surgery and LBP related costs. Variables associated with a PT consult, PT participation, and subsequent outcomes were evaluated with multivariate models. RESULTS: A total of 251 (55%) participants received a PT consult within 7 days of the index LBP visit and 81 (19%) participated in PT. The odds of a PT consult were increased if patients were prescribed non-steroidal anti-inflammatories (aOR = 1.81; 95% confidence interval [CI], 1.0 to 3.27; P = .05) or muscle relaxers (adjusted odds ratio [aOR] = 2.24; 95% CI, 1.03 to 4.87; P = .04). Whereas tobacco users and individual with multiple comorbidities were less likely to receive a PT consult (aOR = 0.52; 95% CI, 0.20 to 0.91) and 0.42 (95% CI, 0.23 to 0.78), respectively). Odds of participating in PT were higher for patients receiving an radiograph at baseline (odds ratio [OR] = 2.63; 95% CI, 1.25 to 5.53) or having multiple comorbidities (OR = 2.96; 95% CI, 1.20 to 7.20). The odds of receiving an opioid prescription over the year following the index visit reduced with a PT consult (aOR = 0.65; 95% CI, 0.43 to 1.00) and with PT participation (aOR = 0.47; 95% CI, 0.24 to 0.92). No differences in LBP related costs over 1 year were noted between any of the groups. CONCLUSIONS: Among Medicaid recipients with new-onset LBP, the index provider's prescription and imaging decisions and patient demographics were associated with PT referrals and participation. A referral to PT and subsequent PT participation was associated with reduced opioid prescriptions during follow-up. There was no difference in overall LBP-related health care costs. PMID- 29180554 TI - Frequency of Cannabis Use Among Primary Care Patients in Washington State. AB - INTRODUCTION: Over 12% of US adults report past-year cannabis use, and among those who use daily, 25% or more have a cannabis use disorder. Use is increasing as legal access expands. Yet, cannabis use is not routinely assessed in primary care, and little is known about use among primary care patients and relevant demographic and behavioral health subgroups. This study describes the prevalence and frequency of past-year cannabis use among primary care patients assessed for use during a primary care visit. METHODS: This observational cohort study included adults who made a visit to primary care clinics with annual behavioral health screening, including a single-item question about frequency past-year cannabis use (March 2015 to February 2016; n = 29,857). Depression, alcohol and other drug use were also assessed by behavioral health screening. Screening results, tobacco use, and diagnoses for past-year behavioral health conditions (e.g., mental health and substance use disorders) were obtained from EHRs. RESULTS: Among patients who completed the cannabis use question (n = 22,095; 74% of eligible patients), 15.3% (14.8% to 15.8%) reported any past-year use: 12.2% (11.8% to 12.6%) less than daily, and 3.1% (2.9%-3.3%) daily. Among 2228 patients age 18 to 29 years, 36.0% (34.0% to 38.0%) reported any cannabis use and 8.1% (7.0% to 9.3%) daily use. Daily cannabis use was common among men age 18 to 29 years who used tobacco or screened positive for depression or used tobacco: 25.5% (18.8% to 32.1%) and 31.7% (23.3% to 40.0%), respectively. CONCLUSIONS: Cannabis use was common in adult primary care patients, especially among younger patients and those with behavioral health conditions. Results highlight the need for primary care approaches to address cannabis use. PMID- 29180555 TI - The Diagnostic Value of the Patient's Reason for Encounter for Diagnosing Cancer in Primary Care. AB - PURPOSE: Family physicians (FPs) have to recognize alarm symptoms and estimate the probability of cancer to manage these symptoms correctly. Mostly, patients start the consultation with a spontaneous statement on why they visit the doctor. This is also called the reason for encounter (RFE). It precedes the interaction and interpretation by FPs and patients. The aim of this study is to investigate the predictive value of alarm symptoms as the RFE for diagnosing cancer in primary care. DESIGN AND SETTING: Retrospective cohort study in a Dutch practice based research network (Family Medicine Network). METHOD: We analyzed all patients >45 years of age listed in the practice-based research network, FaMe net, in the period 1995 to 2014 (118.219 patient years). We focused on a selection of alarm symptoms as defined by the Dutch Cancer Society and Cancer Research UK. We calculated the positive predictive value (PPV) of alarm symptoms, spontaneously mentioned in the beginning of the consultation by the patient (RFE), for diagnosing cancer. RESULTS: The highest PPVs were found for patients spontaneously mentioning a breast lump (PPV 14.8%), postmenopausal bleeding (PPV 3.9%), hemoptysis (PPV 2.7%), rectal bleeding (PPV 2.6%), hematuria (PPV 2.2%) and change in bowel movements (PPV 1.8%). CONCLUSION: Patients think about going to their physician and think about their first uttered statements during the consultation. In the case of cancer, the diagnostic workup during the consultation on alarm symptoms will add to the predictive value of these reasons for encounter. However, it is important to realize that the statement made by the patient entering the consultation room has a significant predictive value in itself. PMID- 29180556 TI - Older Adults' Preferences for When and How to Discuss Life Expectancy in Primary Care. AB - INTRODUCTION: Life expectancy is important to inform a number of clinical decisions in primary care but its communication is challenging for clinicians. METHODS: This qualitative interview study with 40 community-dwelling older adults explored their perspectives on how and when to discuss life expectancy in primary care. RESULTS: Most participants did not want to discuss life expectancy longer than 1 year but were open to being offered discussion by clinicians. Suggestions included using health decline as trigger for discussion and discussing with family members instead of patient. DISCUSSION: Although older adults have varied preferences for the timing and content of life expectancy discussions in primary care, it was generally acceptable for clinicians to offer the opportunity for this type of discussion. PMID- 29180558 TI - Using Drug Prescribing Patterns to Identify Stewards of Cost-Conscious Care. AB - PURPOSE: To characterize family physicians (FPs) who are stewards of care by consistently prescribing omeprazole over esomeprazole. METHODS: Cross-sectional analysis of physicians prescribing omeprazole or esomeprazole under Medicare Part D in 2014. RESULTS: There was a regional trend with 49% of Western FPs but only 6% of Southern FPs rarely prescribing esomeprazole. Physicians had increased odds of being a steward if they worked with a care coordinator (P < .001), at a patient-centered medical home (P < .001), or in a large practice (P < .001). CONCLUSIONS: If these findings are replicated across multiple drugs, future outreach could be conducted based on provider prescribing patterns. PMID- 29180557 TI - Worsening Rural-Urban Gap in Hospital Mortality. AB - BACKGROUND: One out of every 5 Americans live in rural communities. Rural Americans have higher rates of early and preventable deaths outside of the hospital than their urban counterparts. How rurality relates to hospital mortality is unknown. We sought to determine the association between rural versus urban residence and hospital mortality. METHODS: This is a retrospective observational study of 4,412,942 nonmaternal, nonneonatal hospitalizations in 2008, and 3899,464 nonmaternal, nonneonatal hospitalizations in 2013 using all payer, all-age data from the National Inpatient Sample of the Health care Cost and Utilization Project. Using multivariable logistic regression, we report the association between rural versus urban location of residence and hospital mortality, adjusting for chronic disease burden, age, income, and insurance status. RESULTS: The unadjusted probability of hospital mortality for urban patients decreased from 2.51% (95% CI, 2.40 to 2.62) in 2008 to 2.27% (95% CI, 2.22 to 2.32) in 2013 (P < .001). Hospital mortality did not change for rural patients over this same time period (2008: 2.66% [95% CI, 2.57 to 2.74], 2013: 2.66% [95% CI, 2.60 to 2.72]; P = .99). Adjusting for covariates accounted for the rural-urban hospital mortality difference in 2008 (rural: 2.13% [95% CI, 2.05 to 2.21], urban: 2.11% [95% CI, 2.02 to 2.20]; P = .67), but did not fully explain the difference in 2013 (rural: 1.92% [95% CI, 1.87 to 1.97]; urban: 1.76% [95% CI, 1.72 to 1.80], P < .001), resulting in 8416 excess deaths among hospitalized patients from rural areas. CONCLUSION AND RELEVANCE: In 2013, patients living in rural areas of the United States had a greater probability of hospital mortality than their urban counterparts. Explaining excess rural hospital deaths will require further attention to the patient, community, and health system factors that distinguish rural from urban populations. PMID- 29180559 TI - Predicting Risk for Opioid Misuse in Chronic Pain with a Single-Item Measure of Catastrophic Thinking. AB - BACKGROUND: Chronic pain patients are frequently treated with opioid medications in primary care, where brief measures of risk for opioid misuse have great utility. Catastrophic thinking is a clinically relevant and potentially modifiable factor associated with several chronic pain outcomes, including risk for opioid misuse. This study examined the utility of a single-item measure of pain-related catastrophizing in predicting risk of opioid misuse. METHOD: 119 chronic pain patients completed the Coping Strategies Questionnaire catastrophizing item, Pain Catastrophizing Scale (PCS), and Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R). Area under the receiver operator curve (AUC) and linear regression were used to examine predictive utility of the catastrophizing item. RESULTS: The catastrophizing item demonstrated a fair ability to discriminate those with high risk for opioid misuse on the SOAPP-R (AUC = 0.74), whereas the PCS demonstrated good discrimination (AUC = 0.85). The single item alone accounted for 30% of variance in SOAPP-R scores. CONCLUSION: A single question assessing pain catastrophizing has utility for predicting risk for opioid misuse. In addition, it provides the primary care provider with information on a potentially modifiable risk factor that can be addressed within the context of a brief clinical visit. PMID- 29180560 TI - Dysrhythmias with Loperamide Used for Opioid Withdrawal. AB - The antidiarrheal loperamide has had a recent, drastic increase in off-label use as an alternative treatment for symptoms of opioid withdrawal. The concept of this is easily discovered on the Internet and social media, where there are multiple blogs and forums promoting loperamide use at doses of 70 to 200 mg per day. Unfortunately, the serious side effects are not well recognized. Multiple cases of cardiac dysrhythmias contributing to death have been highlighted in recent literature. In November 2016, the US Food & Drug Administration released a statement highlighting the potential heart effects and risk of death with high doses of loperamide.1 This case regards a 22-year-old who took 200 mg of loperamide per day for 2 years as an alternative to methadone in her attempts to wean off heroin. Her subsequent spontaneous collapse, dysrhythmias, and acute hospital treatment are reviewed in detail as they were contradictory to standard therapy and required a multidisciplinary approach. Her outpatient management addressed the complex biological, psychological, and social aspects of her addiction. PMID- 29180561 TI - Notalgia Paresthetica Relieved by Cervical Traction. AB - Notalgia paresthetica is a syndrome of unilateral, chronic pruritis that is associated with burning pain, paresthesia, numbness, and hyperesthesia localized to the medial and inferior scapula. The condition does not respond to anti inflammatory drugs or traditional antipruritic agents and has variable responses to numerous other reported pharmacologic and nonpharmacologic therapies. Although the etiology is thought to be nerve impingement, neurologic and musculoskeletal causes are often not considered in the differential diagnosis. We present a report of a woman with a 2-year history of refractory notalgia paresthetica. Based on spinal imaging showing cervical neuroforaminal stenosis, the patient was prescribed a course of cervical traction. Her symptoms resolved and have not returned after 2 years of followup. We believe this is the first case report of successful treatment of notalgia paresthetica with cervical traction. PMID- 29180562 TI - The Single Graduate Medical Education (GME) Accreditation System Will Change the Future of the Family Medicine Workforce. AB - BACKGROUND: Due to the Accreditation Council for Graduate Medical Education (ACGME)/American Osteopathic Association (AOA) single-accreditation model, the specialty of family medicine may see as many as 150 programs and 500 trainees in AOA-accredited programs seek ACGME accreditation. This analysis serves to better understand the composition of physicians completing family medicine residency training and their subsequent certification by the American Board of Family Medicine. METHODS: We identified residents who completed an ACGME-accredited or dual-accredited family medicine residency program between 2006 and 2016 and cross tabulated the data by graduation year and by educational background (US Medical Graduate-MD [USMG-MD], USMG-DO, or International Medical Graduate-MD [IMG-MD]) to examine the cohort composition trend over time. RESULTS: The number and proportion of osteopaths completing family medicine residency training continues to rise concurrent with a decline in the number and proportion of IMGs. Take Rates for USMG-MDs and USMG-IMGs seem stable; however, the Take Rate for the USMG DOs has generally been rising since 2011. CONCLUSIONS: There is a clear change in the composition of graduating trainees entering the family medicine workforce. As the transition to a single accreditation system for graduate medical education progresses, further shifts in the composition of this workforce should be expected. PMID- 29180563 TI - Strategies for Increasing the Role of Family Medicine in Mexican Health Care Reform. AB - There is little or no role for primary care and family medicine in current health reforms in Mexico. However, robust evidence shows that primary care helps prevent morbidity and mortality and increases health equity. Mexico has participated in several international meetings sponsored by the World Organization of National Colleges, Academies and Academic Associations and the North American Primary Care Research Group that are aimed at increased understanding of national health systems and the need to strengthen primary care for improved health outcomes. From 1 of these meetings the Cancun Manifesto emerged, with a strategic plan to increase the stature and impact of the Mexican College of Family Physicians (COLMEXAC) in strengthening primary care in Mexico. We aim to describe this strategic plan and discuss its early implementation, and for this account to serve as a possible formula for other countries. The 5 specific strategies discussed are 1) the need for consensus on the leading role of the Mexican family physician in the national health system; 2) health ecology research; 3) to improve the perception of patients about the benefits of primary care and family medicine; 4) to organize meetings of health providers, users, and other stakeholders; and 5) to promote the professionalization of COLMEXAC as a legal entity.

PMID- 29180567 TI - Uhrf1 is indispensable for normal limb growth by regulating chondrocyte differentiation through specific gene expression. AB - Transcriptional regulation can be tightly orchestrated by epigenetic regulators. Among these, ubiquitin-like with PHD and RING finger domains 1 (Uhrf1) is reported to have diverse epigenetic functions, including regulation of DNA methylation. However, the physiological functions of Uhrf1 in skeletal tissues remain unclear. Here, we show that limb mesenchymal cell-specific Uhrf1 conditional knockout mice (Uhrf1DeltaLimb/DeltaLimb ) exhibit remarkably shortened long bones that have morphological deformities due to dysregulated chondrocyte differentiation and proliferation. RNA-seq performed on primary cultured chondrocytes obtained from Uhrf1DeltaLimb/DeltaLimb mice showed abnormal chondrocyte differentiation. In addition, integrative analyses using RNA-seq and MBD-seq revealed that Uhrf1 deficiency decreased genome-wide DNA methylation and increased gene expression through reduced DNA methylation in the promoter regions of 28 genes, including Hspb1, which is reported to be an IL1-related gene and to affect chondrocyte differentiation. Hspb1 knockdown in cKO chondrocytes can normalize abnormal expression of genes involved in chondrocyte differentiation, such as Mmp13 These results indicate that Uhrf1 governs cell type-specific transcriptional regulation by controlling the genome-wide DNA methylation status and regulating consequent cell differentiation and skeletal maturation. PMID- 29180568 TI - Maternal Nanog is required for zebrafish embryo architecture and for cell viability during gastrulation. AB - Nanog has been implicated in establishment of pluripotency in mammals and in zygotic genome activation in zebrafish. In this study, we characterize the development of MZnanog (maternal and zygotic null) mutant zebrafish embryos. Without functional Nanog, epiboly is severely affected, embryo axes do not form and massive cell death starts at the end of gastrulation. We show that three independent defects in MZnanog mutants contribute to epiboly failure: yolk microtubule organization required for epiboly is abnormal, maternal mRNA fails to degrade owing to the absence of miR-430, and actin structure of the yolk syncytial layer does not form properly. We further demonstrate that the cell death in MZnanog embryos is cell-autonomous. Nanog is necessary for correct spatial expression of the ventral-specifying genes bmp2b, vox and vent, and the neural transcription factor her3 It is also required for the correctly timed activation of endoderm genes and for the degradation of maternal eomesa mRNA via miR-430. Our findings suggest that maternal Nanog coordinates several gene regulatory networks that shape the embryo during gastrulation. PMID- 29180570 TI - Perturbation of canonical and non-canonical BMP signaling affects migration, polarity and dendritogenesis of mouse cortical neurons. AB - Bone morphogenetic protein (BMP) signaling has been implicated in the regulation of patterning of the forebrain and as a regulator of neurogenesis and gliogenesis in the mammalian cortex. However, its role in other aspects of cortical development in vivo remains unexplored. We hypothesized that BMP signaling might regulate additional processes during the development of cortical neurons after observing active BMP signaling in a spatiotemporally dynamic pattern in the mouse cortex. Our investigation revealed that BMP signaling specifically regulates the migration, polarity and the dendritic morphology of upper layer cortical neurons born at E15.5. On further dissection of the role of canonical and non-canonical BMP signaling in each of these processes, we found that migration of these neurons is regulated by both pathways. Their polarity, however, appears to be affected more strongly by canonical BMP signaling, whereas dendritic branch formation appears to be somewhat more strongly affected by LIMK-mediated non canonical BMP signaling. PMID- 29180569 TI - The skeletal phenotype of achondrogenesis type 1A is caused exclusively by cartilage defects. AB - Inactivating mutations in the ubiquitously expressed membrane trafficking component GMAP-210 (encoded by Trip11) cause achondrogenesis type 1A (ACG1A). ACG1A is surprisingly tissue specific, mainly affecting cartilage development. Bone development is also abnormal, but as chondrogenesis and osteogenesis are closely coupled, this could be a secondary consequence of the cartilage defect. A possible explanation for the tissue specificity of ACG1A is that cartilage and bone are highly secretory tissues with a high use of the membrane trafficking machinery. The perinatal lethality of ACG1A prevents investigating this hypothesis. We therefore generated mice with conditional Trip11 knockout alleles and inactivated Trip11 in chondrocytes, osteoblasts, osteoclasts and pancreas acinar cells, all highly secretory cell types. We discovered that the ACG1A skeletal phenotype is solely due to absence of GMAP-210 in chondrocytes. Mice lacking GMAP-210 in osteoblasts, osteoclasts and acinar cells were normal. When we inactivated Trip11 in primary chondrocyte cultures, GMAP-210 deficiency affected trafficking of a subset of chondrocyte-expressed proteins rather than globally impairing membrane trafficking. Thus, GMAP-210 is essential for trafficking specific cargoes in chondrocytes but is dispensable in other highly secretory cells. PMID- 29180571 TI - The primary role of zebrafish nanog is in extra-embryonic tissue. AB - The role of the zebrafish transcription factor Nanog has been controversial. It has been suggested that Nanog is primarily required for the proper formation of the extra-embryonic yolk syncytial layer (YSL) and only indirectly regulates gene expression in embryonic cells. In an alternative scenario, Nanog has been proposed to directly regulate transcription in embryonic cells during zygotic genome activation. To clarify the roles of Nanog, we performed a detailed analysis of zebrafish nanog mutants. Whereas zygotic nanog mutants survive to adulthood, maternal-zygotic (MZnanog) and maternal mutants exhibit developmental arrest at the blastula stage. In the absence of Nanog, YSL formation and epiboly are abnormal, embryonic tissue detaches from the yolk, and the expression of dozens of YSL and embryonic genes is reduced. Epiboly defects can be rescued by generating chimeric embryos of MZnanog embryonic tissue with wild-type vegetal tissue that includes the YSL and yolk cell. Notably, cells lacking Nanog readily respond to Nodal signals and when transplanted into wild-type hosts proliferate and contribute to embryonic tissues and adult organs from all germ layers. These results indicate that zebrafish Nanog is necessary for proper YSL development but is not directly required for embryonic cell differentiation. PMID- 29180572 TI - The ATPase activity of Asna1/TRC40 is required for pancreatic progenitor cell survival. AB - Asna1, also known as TRC40, is implicated in the delivery of tail-anchored (TA) proteins into the endoplasmic reticulum (ER), in vesicle-mediated transport, and in chaperoning unfolded proteins during oxidative stress/ATP depletion. Here, we show that Asna1 inactivation in pancreatic progenitor cells leads to redistribution of the Golgi TA SNARE proteins syntaxin 5 and syntaxin 6, Golgi fragmentation, and accumulation of cytosolic p62+ puncta. Asna1-/- multipotent progenitor cells (MPCs) selectively activate integrated stress response signaling and undergo apoptosis, thereby disrupting endocrine and acinar cell differentiation, resulting in pancreatic agenesis. Rescue experiments implicate the Asna1 ATPase activity and a CXXC di-cysteine motif in ensuring Golgi integrity, syntaxin 5 localization and MPC survival. Ex vivo inhibition of retrograde transport reproduces the perturbed Golgi morphology, and syntaxin 5 and syntaxin 6 expression, whereas modulation of p53 activity, using PFT-alpha and Nutlin-3, prevents or reproduces apoptosis in Asna1-deficient and wild-type MPCs, respectively. These findings support a role for the Asna1 ATPase activity in ensuring the survival of pancreatic MPCs, possibly by counteracting p53 mediated apoptosis. PMID- 29180574 TI - miR-126-5p promotes retinal endothelial cell survival through SetD5 regulation in neurons. AB - MicroRNAs are key regulators of angiogenesis, as illustrated by the vascular defects observed in miR-126-deficient animals. The miR-126 duplex gives rise to two mature microRNAs (miR-126-3p and -5p). The vascular defects in these mutant animals were attributed to the loss of miR-126-3p but the role of miR-126-5p during normal angiogenesis in vivo remains unknown. Here, we show that miR-126-5p is expressed in endothelial cells but also by retinal ganglion cells (RGCs) of the mouse postnatal retina and participates in protecting endothelial cells from apoptosis during the establishment of the retinal vasculature. miR-126-5p negatively controls class 3 semaphorin protein (Sema3A) in RGCs through the repression of SetD5, an uncharacterized member of the methyltransferase family of proteins. In vitro, SetD5 controls Sema3A expression independently of its SET domain and co-immunoprecipitates with BRD2, a bromodomain protein that recruits transcription regulators onto the chromatin. Both SetD5 and BRD2 bind to the transcription start site and to upstream promoter regions of the Sema3a locus and BRD2 is necessary for the regulation of Sema3A expression by SetD5. Thus, neuronally expressed miR-126-5p regulates angiogenesis by protecting endothelial cells of the developing retinal vasculature from apoptosis.

PMID- 29180573 TI - Plasticity within the niche ensures the maintenance of a Sox2+ stem cell population in the mouse incisor. AB - In mice, the incisors grow throughout the animal's life, and this continuous renewal is driven by dental epithelial and mesenchymal stem cells. Sox2 is a principal marker of the epithelial stem cells that reside in the mouse incisor stem cell niche, called the labial cervical loop, but relatively little is known about the role of the Sox2+ stem cell population. In this study, we show that conditional deletion of Sox2 in the embryonic incisor epithelium leads to growth defects and impairment of ameloblast lineage commitment. Deletion of Sox2 specifically in Sox2+ cells during incisor renewal revealed cellular plasticity that leads to the relatively rapid restoration of a Sox2-expressing cell population. Furthermore, we show that Lgr5-expressing cells are a subpopulation of dental Sox2+ cells that also arise from Sox2+ cells during tooth formation. Finally, we show that the embryonic and adult Sox2+ populations are regulated by distinct signalling pathways, which is reflected in their distinct transcriptomic signatures. Together, our findings demonstrate that a Sox2+ stem cell population can be regenerated from Sox2- cells, reinforcing its importance for incisor homeostasis.

PMID- 29180585 TI - A trivalent HCV vaccine elicits broad and synergistic polyclonal antibody response in mice and rhesus monkey. AB - OBJECTIVE: Despite the development of highly effective direct-acting antivirals, a prophylactic vaccine is needed for eradicating HCV. A major hurdle of HCV vaccine development is to induce immunity against HCV with high genome diversity. We previously demonstrated that a soluble E2 (sE2) expressed from insect cells induces broadly neutralising antibodies (NAbs) and prevents HCV infection. The objective of this study is to develop a multivalent HCV vaccine to increase the antigenic coverage. DESIGN: We designed a trivalent vaccine containing sE2 from genotype 1a, 1b and 3a. Mice and rhesus macaques were immunised with monovalent or trivalent sE2 vaccine, and sera or purified immunoglobulin were assessed for neutralisation against a panel of cell culture-derived virion (HCVcc) of genotype 1-7 in cell culture. Splenocytes from the vaccinated macaques were assessed for HCV-specific T cell response. RESULTS: We showed that the trivalent vaccine elicited pangenotypic NAbs in mice, which neutralised HCVcc of all the seven genotypes more potently than the monovalent vaccine. Further analyses demonstrated that each sE2 component of this trivalent vaccine elicited unique spectrum of NAbs which acted synergistically to inhibit HCV infection. Finally, the trivalent vaccine triggered stronger and more uniform multigenotypic neutralising antibody response than the monovalent vaccine in rhesus macaques. CONCLUSIONS: In summary, we developed a trivalent HCV vaccine that induces broad and synergistic-acting neutralising antibodies in mice and non-human primates.

PMID- 29180590 TI - Examining tRNA 3'-ends in Escherichia coli: teamwork between CCA-adding enzyme, RNase T, and RNase R. AB - tRNA maturation and quality control are crucial for proper functioning of these transcripts in translation. In several organisms, defective tRNAs were shown to be tagged by poly(A) or CCACCA tails and subsequently degraded by 3' exonucleases. In a deep-sequencing analysis of tRNA 3'-ends, we detected the CCACCA tag also in Escherichia coli However, this tag closely resembles several 3'-trailers of tRNA precursors targeted for maturation and not for degradation. Here, we investigate the ability of two important exonucleases, RNase R and RNase T, to distinguish tRNA precursors with a native 3'-trailer from tRNAs with a CCACCA tag. Our results show that the degrading enzyme RNase R breaks down both tRNAs primed for degradation as well as precursor transcripts, indicating that it is a rather nonspecific RNase. RNase T, a main processing exonuclease involved in trimming of 3'-trailers, is very inefficient in converting the CCACCA-tagged tRNA into a mature transcript. Hence, while both RNases compete for trailer-containing tRNA precursors, the inability of RNase T to process CCACCA tails ensures that defective tRNAs cannot reenter the functional tRNA pool, representing a safeguard to avoid detrimental effects of tRNAs with erroneous integrity on protein synthesis. Furthermore, these data indicate that the RNase T-mediated end turnover of the CCA sequence represents a means to deliver a tRNA to a repeated quality control performed by the CCA-adding enzyme. Hence, originally described as a futile side reaction, the tRNA end turnover seems to fulfill an important function in the maintenance of the tRNA pool in the cell. PMID- 29180591 TI - Developing outcome measures assessing wound management and patient experience: a mixed methods study. AB - OBJECTIVES: To develop outcome measures to assess practical management of primary surgical wounds and patient experience. DESIGN: Mixed methods, including qualitative interviews and data extraction from published randomised controlled trials (RCTs). SETTING: Two university-teaching NHS hospitals and three district NHS hospitals in the South West and Midlands regions of England. PARTICIPANTS: Sixty-four patients and 15 healthcare professionals from abdominal general surgical specialities and obstetrics (caesarean section). METHODS: Measures were developed according to standard guidelines to identify issues relevant to patients' experiences of surgical wounds and dressings, including analysis of existing RCT outcomes and semi-structured interviews. These were written into provisional questionnaire items for a single outcome measure. Cognitive interviews with patients and healthcare professionals assessed face validity, acceptability and relevance. Findings from interviews were regularly shared with the study team who suggested amendments to modify and reword items to improve understanding before further iterative testing with patients and healthcare professionals. RESULTS: Analyses of existing RCT outcomes and interviews produced a total of 69 issues. Pretesting and iterative revision established the need for two separate measures. One measure addresses healthcare professionals' experience of wound management in two key areas: exudate and its impact, and allergic reactions to the dressing. The other measure addresses patients' experience of wounds in seven key areas: wound comfort, dressing removal, dressings to protect the wound, impact on daily activities, ease of movement, anxiety about the wound and satisfaction with dressing. Each measure took less than five min to complete and both were understood and acceptable to patients and healthcare professionals. CONCLUSION: This in-depth study has developed two measures to assess practical management of primary surgical wounds and patient experience. Further work to test their validity, reliability and application to other settings is now required. TRIAL REGISTRATION NUMBER: HTA - 12/200/04; Pre-results. PMID- 29180592 TI - Cost-effectiveness of a preferred intensity exercise programme for young people with depression compared with treatment as usual: an economic evaluation alongside a clinical trial in the UK. AB - OBJECTIVES: To assess the cost-effectiveness of preferred intensity exercise programme for young people with depression compared with a treatment as usual control group. DESIGN: A 'within trial' cost-effectiveness and cost-utility analysis conducted alongside a randomised controlled trial. The perspective of the analysis was the UK National Health Service and social services. SETTING: The intervention was provided in a community leisure centre setting. PARTICIPANTS: 86 young people aged 14-17 years attending Tier 2 and Tier 3 CAMHS (Child and Adolescent Mental Health Services) outpatient services presenting with depression. INTERVENTIONS: The intervention comprised 12 separate sessions of circuit training over a 6-week period. Sessions were supervised by a qualified exercise therapist. Participants also received treatment as usual. The comparator group received treatment as usual. RESULTS: We found improvements in the Children's Depression Inventory-2 (CDI-2) and estimated cost-effectiveness at L61 per point improvement in CDI-2 for the exercise group compared with control. We found no evidence that the exercise intervention led to differences in quality adjusted life years (QALY). QALYs were estimated using the EQ-5D-5L (5-level version of EuroQol-5 dimension). CONCLUSIONS: There is evidence that exercise can be an effective intervention for adolescents with depression and the current study shows that preferred intensity exercise could also represent a cost effective intervention in terms of the CDI-2.

AB - OBJECTIVE: To explore perceptions of illness, the decisions to consult and the acceptability of delayed antibiotic prescriptions and self-help treatments for respiratory tract infections (RTIs). DESIGN: Qualitative semistructured interview study. SETTING: UK primary care. PARTICIPANTS: 20 adult patients who had been participating in the 'PIPS' (Pragmatic Ibuprofen Paracetamol and Steam) trial in the South of England. METHOD: Semistructured telephone interviews were conducted with participants to explore their experiences and views on various treatments for RTI. RESULTS: Participants had concerns about symptoms that were not clinically serious and were mostly unaware of the natural history of RTIs, but were aware of the limitations of antibiotics and did not expect them with every consultation. Most viewed delayed prescriptions positively and had no strong preference over which technique is used to deliver the delayed antibiotic, but some patients received mixed messages, such as being told their infection was viral then being given an antibiotic, or were sceptical about the rationale. Participants disliked self-help treatments that involved taking medication and were particularly concerned about painkillers in combination. Steam inhalation was viewed as only moderately helpful for mild symptoms. CONCLUSION: Delayed prescribing is acceptable no matter how the delay is operationalised, but explanation of the rationale is needed and care taken to minimise mixed messages about the severity of illnesses and causation by viruses or bacteria. Better access is needed to good natural history information, and the signs and symptoms requiring or not requiring general practitioner advice. Significant concerns about paracetamol, ibuprofen and steam inhalation are likely to need careful exploration in the consultation. PMID- 29180594 TI - Referrers' point of view on the referral process to neurosurgery and opinions on neurosurgeons: a large-scale regional survey in the UK. AB - OBJECTIVES: There is an increased reliance on online referral systems (ORS) within neurosurgical departments across the UK. Opinions of neurosurgeons on ORS are extensively reported but those of referrers have hardly been sought. Our study aims at ascertaining our referring colleagues' views on our ORS and its impact on patient care, their opinions on neurosurgeons and how to improve our referral process. SETTING: 14 district general hospitals and one teaching hospital. PARTICIPANTS: 641 healthcare professionals across a range of medical and surgical specialties including doctors of all grades, nurses and physiotherapists. Survey responses were obtained by medical students using a smartphone application. RESULTS: Although 92% of respondents were aware of the ORS, 74% would routinely phone the on-call registrar either before or after making referrals online. The majority (44%) believed their call to relate to a life-threatening emergency. 62% of referrers considered the ORS helpful in informing patients' care and 48% had a positive opinion of their interaction with neurosurgical registrars. On ways to improve the ORS, 50% selected email/text confirmation of response sent to referrers and 16% to referring consultants. CONCLUSION: Our results confirm that referrers feel that using our ORS positively impacts patient care but that it remains in need of improvement in order to better suit our colleagues' needs when it comes to managing neurosurgical patients. We feel that the promotion of neurosurgical education and mitigation of the effects of adverse workplace human factors are likely to achieve the common goal of neurosurgeons and referrers alike: a high standard in patient care.

In mammals, this modification is reversible and plays broad roles in the regulation of mRNA metabolism and processing. Despite its importance, previous studies on the role and mechanism of m6A methylation in Arabidopsis thaliana have been limited. Here, we report that ALKBH10B is a demethylase that oxidatively reverses m6A methylation in mRNA in vitro and in vivo. Depletion of ALKBH10B in the alkbh10b mutant delays flowering and represses vegetative growth. Complementation with wild-type ALKBH10B, but not a catalytically inactive mutant (ALKBH10B H366A/E368A), rescues these effects in alkbh10b-1 mutant plants, suggesting the observed phenotypes are controlled by the catalytic action of ALKBH10B We show that ALKBH10B-mediated mRNA demethylation affects the stability of target transcripts, thereby influencing floral transition. We identified 1190 m6A hypermethylated transcripts in the alkbh10b-1 mutant involved in plant development. The discovery and characterization of the archetypical RNA demethylase in Arabidopsis sheds light on the occurrence and functional role(s) of reversible mRNA methylation in plants and defines the role of m6A RNA modification in Arabidopsis floral transition.

AB - Polyploidy is an important feature of plant genomes, but the nature of many polyploidization events remains to be elucidated. Here, we demonstrate that the evolutionary fates of the subgenomes in maize (Zea mays) and soybean (Glycine max) have followed different trajectories. One subgenome has been subject to relaxed selection, lower levels of gene expression, higher rates of transposable element accumulation, more small interfering RNAs and DNA methylation around genes, and higher rates of gene loss in maize, whereas none of these features were observed in soybean. Nevertheless, individual gene pairs exhibit differentiation with respect to these features in both species. In addition, we observed a higher number of chromosomal rearrangements and higher frequency of retention of duplicated genes in soybean than in maize. Furthermore, soybean "singletons" were found to be more frequently tandemly duplicated than "duplicates" in soybean, which may, to some extent, counteract the genome imbalance caused by gene loss. We propose that unlike in maize, in which two subgenomes were distinct prior to the allotetraploidization event and thus experienced global differences in selective constraints, in soybean, the two subgenomes were far less distinct prior to polyploidization, such that individual gene pairs, rather than subgenomes, experienced stochastic differences over longer periods of time, resulting in retention of the majority of duplicates. PMID- 29180599 TI - Too hard to swallow: a secret secondary defence of an aposematic insect. AB - Anti-predator strategies are significant components of adaptation in prey species. Aposematic prey are expected to possess effective defences that have evolved simultaneously with their warning colours. This study tested the hypothesis of the defensive function and ecological significance of the hard body in aposematic Pachyrhynchus weevils pioneered by Alfred Russel Wallace nearly 150 years ago. We used predation trials with Japalura tree lizards to assess the survivorship of 'hard' (mature) versus 'soft' (teneral) and 'clawed' (intact) versus 'clawless' (surgically removed) weevils. The ecological significance of the weevil's hard body was evaluated by assessing the hardness of the weevils, the local prey insects, and the bite forces of the lizard populations. The existence of toxins or deterrents in the weevil was examined by gas chromatography-mass spectrometry (GC-MS). All 'hard' weevils were instantly spat out after being bitten once and survived attacks by the lizards. In contrast, the 'soft' weevils were chewed and subsequently swallowed. The results were the same regardless of the presence or absence of the weevil's tarsal claws. The hardness of 'hard' Pachyrhynchus weevils was significantly higher than the average hardness of other prey insects in the same habitat and the mean bite forces of the local lizards. The four candidate compounds of the weevil identified by GC-MS had no known toxic or repellent functions against vertebrates. These results reveal that the hardness of aposematic prey functions as an effective secondary defence, and they provide a framework for understanding the spatio-temporal interactions between vertebrate predators and aposematic insect prey. PMID- 29180598 TI - Intracellular Distribution of Manganese by the Trans-Golgi Network Transporter NRAMP2 Is Critical for Photosynthesis and Cellular Redox Homeostasis. AB - Plants require trace levels of manganese (Mn) for survival, as it is an essential cofactor in oxygen metabolism, especially O2 production via photosynthesis and the disposal of superoxide radicals. These processes occur in specialized organelles, requiring membrane-bound intracellular transporters to partition Mn between cell compartments. We identified an Arabidopsis thaliana member of the NRAMP family of divalent metal transporters, NRAMP2, which functions in the intracellular distribution of Mn. Two knockdown alleles of NRAMP2 showed decreased activity of photosystem II and increased oxidative stress under Mn deficient conditions, yet total Mn content remained unchanged. At the subcellular level, these phenotypes were associated with a loss of Mn content in vacuoles and chloroplasts. NRAMP2 was able to rescue the mitochondrial yeast mutant mtm1? In plants, NRAMP2 is a resident protein of the trans-Golgi network. NRAMP2 may act indirectly on downstream organelles by building up a cytosolic pool that is used to feed target compartments. Moreover, not only does the nramp2 mutant accumulate superoxide ions, but NRAMP2 can functionally replace cytosolic superoxide dismutase in yeast, indicating that the pool of Mn displaced by NRAMP2 is required for the detoxification of reactive oxygen species. PMID- 29180600 TI - Integration of celestial compass cues in the central complex of the locust brain. AB - Many insects rely on celestial compass cues such as the polarization pattern of the sky for spatial orientation. In the desert locust, the central complex (CX) houses multiple sets of neurons, sensitive to the oscillation plane of polarized light and thus probably acts as an internal polarization compass. We investigated whether other sky compass cues like direct sunlight or the chromatic gradient of the sky might contribute to this compass. We recorded from polarization-sensitive CX neurons while an unpolarized green or ultraviolet light spot was moved around the head of the animal. All types of neuron that were sensitive to the plane of polarization (E-vector) above the animal also responded to the unpolarized light spots in an azimuth-dependent way. The tuning to the unpolarized light spots was independent of wavelength, suggesting that the neurons encode solar azimuth based on direct sunlight and not on the sky chromatic gradient. Two cell types represented the natural 90 deg relationship between solar azimuth and zenithal E vector orientation, providing evidence to suggest that solar azimuth information supports the internal polarization compass. Most neurons showed advances in their tuning to the E-vector and the unpolarized light spots dependent on rotation direction, consistent with anticipatory signaling. The amplitude of responses and its variability were dependent on the level of background firing, possibly indicating different internal states. The integration of polarization and solar azimuth information strongly suggests that besides the polarization pattern of the sky, direct sunlight might be an important cue for sky compass navigation in the locust. PMID- 29180601 TI - Widespread utilization of passive energy recapture in swimming medusae. AB - Recently, it has been shown that some medusae are capable of swimming very efficiently, i.e. with a low cost of transport, and that this is in part due to passive energy recapture (PER) which occurs during bell relaxation. We compared the swimming kinematics among a diverse array of medusae, varying in taxonomy, morphology and propulsive and foraging modes, in order to evaluate the prevalence of PER in medusae. We found that while PER was common among taxa, the magnitude of the contribution to overall swimming varied greatly. The ability of medusae to utilize PER was not related to morphology and swimming performance but was controlled by their swimming kinematics. Utilizing PER required the medusae to pause after bell expansion and individuals could modulate their PER by changing their pause duration. PER can greatly enhance swimming efficiency but there appear to be trade-offs associated with utilizing PER. PMID- 29180602 TI - Respiratory mechanics and morphology of Tibetan and Andean high-altitude geese with divergent life histories. AB - High-altitude bar-headed geese (Anser indicus) and Andean geese (Chloephaga melanoptera) have been shown to preferentially increase tidal volume over breathing frequency when increasing ventilation during exposure to hypoxia. Increasing tidal volume is a more effective breathing strategy but is also thought to be more mechanically and metabolically expensive. We asked whether there might be differences in the mechanics or morphology of the respiratory systems of high-altitude transient bar-headed geese and high-altitude resident Andean geese that could minimize the cost of breathing more deeply. We compared these two species with a low-altitude migratory species, the barnacle goose (Branta leucopsis). We ventilated anesthetized birds to measure mechanical properties of the respiratory system and used CT scans to quantify respiratory morphology. We found that the respiratory system of Andean geese was disproportionately larger than that of the other two species, allowing use of a deeper breathing strategy for the same energetic cost. The relative size of the respiratory system, especially the caudal air sacs, of bar-headed geese was also larger than that of barnacle geese. However, when normalized to respiratory system size, the mechanical cost of breathing did not differ significantly among these three species, indicating that deeper breathing is enabled by morphological but not mechanical differences between species. The metabolic cost of breathing was estimated to be <1% of basal metabolic rate at rest in normoxia. Because of differences in the magnitude of the ventilatory response, the cost of breathing was estimated to increase 7- to 10-fold in bar-headed and barnacle geese in severe hypoxia, but less than 1-fold in Andean geese exposed to the same low atmospheric PO2. PMID- 29180603 TI - Metabolome dynamics of diapause in the butterfly Pieris napi: distinguishing maintenance, termination and post-diapause phases. AB - Diapause is a deep resting stage facilitating temporal avoidance of unfavourable environmental conditions, and is used by many insects to adapt their life cycle to seasonal variation. Although considerable work has been invested in trying to understand each of the major diapause stages (induction, maintenance and termination), we know very little about the transitions between stages, especially diapause termination. Understanding diapause termination is crucial for modelling and predicting spring emergence and winter physiology of insects, including many pest insects. In order to gain these insights, we investigated metabolome dynamics across diapause development in pupae of the butterfly Pieris napi, which exhibits adaptive latitudinal variation in the length of endogenous diapause that is uniquely well characterized. By employing a time-series experiment, we show that the whole-body metabolome is highly dynamic throughout diapause and differs between pupae kept at a diapause-terminating (low) temperature and those kept at a diapause-maintaining (high) temperature. We show major physiological transitions through diapause, separate temperature-dependent from temperature-independent processes and identify significant patterns of metabolite accumulation and degradation. Together, the data show that although the general diapause phenotype (suppressed metabolism, increased cold tolerance) is established in a temperature-independent fashion, diapause termination is temperature dependent and requires a cold signal. This revealed several metabolites that are only accumulated under diapause-terminating conditions and degraded in a temperature-unrelated fashion during diapause termination. In conclusion, our findings indicate that some metabolites, in addition to functioning as cryoprotectants, for example, are candidates for having regulatory roles as metabolic clocks or time-keepers during diapause. PMID- 29180605 TI - Cell-Free DNA and Circulating Tumor Cells: Comprehensive Liquid Biopsy Analysis in Advanced Breast Cancer. AB - Purpose: Liquid biopsy provides a real-time assessment of metastatic breast cancer (MBC). We evaluated the utility of combining circulating tumor cells (CTC) and circulating tumor DNA (ctDNA) to predict prognosis in MBC.Experimental Design: We conducted a retrospective study of 91 patients with locally advanced breast cancer and MBC. CTCs were enumerated by CellSearch; the plasma-based assay was performed utilizing Guardant360 and the survival analysis using Kaplan-Meier curves.Results: Eighty-four patients had stage IV cancer, and 7 patients had no metastases. Eighty patients had CTC analysis: median number 2 (0-5,612). Blood samples [232 of 277 (84%)] had mutations. The average ctDNA fraction was 4.5% (0 88.2%) and number of alterations 3 (0-27); the most commonly mutated genes were TP53 (52%), PIK3CA (40%), and ERBB2 (20%). At the time of analysis, 36 patients (39.6%) were dead. The median follow-up for CTCs was 9 months; for ctDNA, it was 9.9 months. For CTCs and ctDNA, respectively, progression-free survival (PFS) was 4.2 and 5.2 months and overall survival (OS) was 18.7 and 21.5 months. There was a statistically significant difference in PFS and OS for baseline CTCs < 5 versus CTCs >= 5 (P = 0.021 and P = 0.0004, respectively); %ctDNA < 0.5 versus >= 0.5 (P = 0.003 and P = 0.012); number of alterations < 2 versus >= 2 (P = 0.059 borderline and P = 0.0015). A significant association by Fisher exact test was found between the number of alterations and the %ctDNA in the baseline sample (P < 0.0001).Conclusions: The study demonstrated that liquid biopsy is an effective prognostic tool.

PMID- 29180604 TI - Classifying Colorectal Cancer by Tumor Location Rather than Sidedness Highlights a Continuum in Mutation Profiles and Consensus Molecular Subtypes. AB - Purpose: Colorectal cancers are classified as right/left-sided based on whether they occur before/after the splenic flexure, with established differences in molecular subtypes and outcomes. However, it is unclear if this division is optimal and whether precise tumor location provides further information.Experimental Design: In 1,876 patients with colorectal cancer, we compared mutation prevalence and overall survival (OS) according to side and location. Consensus molecular subtype (CMS) was compared in a separate cohort of 608 patients.Results: Mutation prevalence differed by side and location for TP53, KRAS, BRAFV600, PIK3CA, SMAD4, CTNNB1, GNAS, and PTEN Within left- and right sided tumors, there remained substantial variations in mutation rates. For example, within right-sided tumors, RAS mutations decreased from 70% for cecal, to 43% for hepatic flexure location (P = 0.0001), while BRAFV600 mutations increased from 10% to 22% between the same locations (P < 0.0001). Within left sided tumors, the sigmoid and rectal region had more TP53 mutations (P = 0.027), less PIK3CA (P = 0.0009), BRAF (P = 0.0033), or CTNNB1 mutations (P < 0.0001), and less MSI (P < 0.0001) than other left-sided locations. Despite this, a left/right division preceding the transverse colon maximized prognostic differences by side and transverse colon tumors had K-modes mutation clustering that appeared more left than right sided. CMS profiles showed a decline in CMS1 and CMS3 and rise in CMS2 prevalence moving distally.Conclusions: Current right/left classifications may not fully recapitulate regional variations in tumor biology. Specifically, the sigmoid-rectal region appears unique and the transverse colon is distinct from other right-sided locations. Clin Cancer Res; 24(5); 1062-72.

PMID- 29180606 TI - Novel BAFF-Receptor Antibody to Natively Folded Recombinant Protein Eliminates Drug-Resistant Human B-cell Malignancies In Vivo. AB - Purpose: mAbs such as anti-CD20 rituximab are proven therapies in B-cell malignancies, yet many patients develop resistance. Novel therapies against alternative targets are needed to circumvent resistance mechanisms. We sought to generate mAbs against human B-cell-activating factor receptor (BAFF-R/TNFRSF13C), which has not yet been targeted successfully for cancer therapy.Experimental Design: Novel mAbs were generated against BAFF-R, expressed as a natively folded cell surface immunogen on mouse fibroblast cells. Chimeric BAFF-R mAbs were developed and assessed for in vitro and in vivo monotherapy cytotoxicity. The chimeric mAbs were tested against human B-cell tumor lines, primary patient samples, and drug-resistant tumors.Results: Chimeric antibodies bound with high affinity to multiple human malignant B-cell lines and induced potent antibody dependent cellular cytotoxicity (ADCC) against multiple subtypes of human lymphoma and leukemia, including primary tumors from patients who had relapsed after anti-CD20 therapy. Chimeric antibodies also induced ADCC against ibrutinib resistant and rituximab-insensitive CD20-deficient variant lymphomas, respectively. Importantly, they demonstrated remarkable in vivo growth inhibition of drug-resistant tumor models in immunodeficient mice.Conclusions: Our method generated novel anti-BAFF-R antibody therapeutics with remarkable single-agent antitumor effects. We propose that these antibodies represent an effective new strategy for targeting and treating drug-resistant B-cell malignancies and warrant further development. Clin Cancer Res; 24(5); 1114-23.

AB - Purpose: Small-cell carcinoma of the bladder (SCCB) is a rare and aggressive neuroendocrine tumor with a dismal prognosis and limited treatment options. As SCCB is histologically indistinguishable from small-cell lung cancer, a shared pathogenesis and cell of origin has been proposed. The aim of this study is to determine whether SCCBs arise from a preexisting urothelial carcinoma or share a molecular pathogenesis in common with small-cell lung cancer.Experimental Design: We performed an integrative analysis of 61 SCCB tumors to identify histology- and organ-specific similarities and differences.Results: SCCB has a high somatic mutational burden driven predominantly by an APOBEC-mediated mutational process. TP53, RB1, and TERT promoter mutations were present in nearly all samples. Although these events appeared to arise early in all affected tumors and likely reflect an evolutionary branch point that may have driven small-cell lineage differentiation, they were unlikely the founding transforming event, as they were often preceded by diverse and less common driver mutations, many of which are common in bladder urothelial cancers, but not small-cell lung tumors. Most patient tumors (72%) also underwent genome doubling (GD). Although arising at different chronologic points in the evolution of the disease, GD was often preceded by biallelic mutations in TP53 with retention of two intact copies.Conclusions: Our findings indicate that small-cell cancers of the bladder and lung have a convergent but distinct pathogenesis, with SCCBs arising from a cell of origin shared with urothelial bladder cancer.

PMID- 29180608 TI - t-Darpp Activates IGF-1R Signaling to Regulate Glucose Metabolism in Trastuzumab Resistant Breast Cancer Cells. AB - Purpose: Increased glycolysis and glucose dependence is a hallmark of malignancy that enables tumors to maximize cell proliferation. In HER2+ cancers, an increase in glycolytic capacity is associated with trastuzumab resistance. IGF-1R activation and t-Darpp overexpression both confer trastuzumab resistance in breast cancer. We therefore investigated a role for IGF-1R and t-Darpp in regulating glycolytic capacity in HER2+ breast cancers.Experimental Design: We examined the relationship between t-Darpp and IGF-1R expression in breast tumors and their respective relationships with patient survival. To assess t-Darpp's metabolic effects, we used the Seahorse flux analyzer to measure glucose metabolism in trastuzumab-resistant SK-BR-3 cells (SK.HerR) that have high endogenous t-Darpp levels and SK.tDrp cells that stably overexpress exogenous t Darpp. To investigate t-Darpp's mechanism of action, we evaluated t-Darpp:IGF-1R complexes by coimmunoprecipitation and proximity ligation assays. We used pathway specific inhibitors to study the dependence of t-Darpp effects on IGF-1R signaling. We used siRNA knockdown to determine whether glucose reliance in SK.HerR cells was mediated by t-Darpp.Results: In breast tumors, PPP1R1B mRNA levels were inversely correlated with IGF-1R mRNA levels and directly associated with shorter overall survival. t-Darpp overexpression was sufficient to increase glucose metabolism in SK.tDrp cells and essential for the glycolytic phenotype of SK.HerR cells. Recombinant t-Darpp stimulated glucose uptake, glycolysis, and IGF 1R-Akt signaling in SK-BR-3 cells. Finally, t-Darpp stimulated IGF-1R heterodimerization with ErbB receptors and required IGF-1R signaling to confer its metabolic effects.Conclusions: t-Darpp activates IGF-1R signaling through heterodimerization with EGFR and HER2 to stimulate glycolysis and confer trastuzumab resistance.

AB - Sensory-guided behaviors require the transformation of sensory information into task-specific motor commands. Prior research on sensorimotor integration has emphasized visuomotor processes in the context of simplified orienting movements in controlled laboratory tasks rather than an animal's more complete, natural behavioral repertoire. Here, we conducted a series of neural recording experiments in the midbrain superior colliculus (SC) of echolocating bats engaged in a sonar target-tracking task that invoked dynamic active sensing behaviors. We hypothesized that SC activity in freely behaving animals would reveal dynamic shifts in neural firing patterns within and across sensory, sensorimotor, and premotor layers. We recorded neural activity in the SC of freely echolocating bats (three females and one male) and replicated the general trends reported in other species with sensory responses in the dorsal divisions and premotor activity in ventral divisions of the SC. However, within this coarse functional organization, we discovered that sensory and motor neurons are comingled within layers throughout the volume of the bat SC. In addition, as the bat increased pulse rate adaptively to increase resolution of the target location with closing distance, the activity of sensory and vocal premotor neurons changed such that auditory response times decreased, and vocal premotor lead times shortened. This finding demonstrates that SC activity can be modified dynamically in concert with adaptive behaviors and suggests that an integrated functional organization within SC laminae supports rapid and local integration of sensory and motor signals for natural, adaptive behaviors.SIGNIFICANCE STATEMENT Natural sensory-guided behaviors involve the rapid integration of information from the environment to direct flexible motor actions. The vast majority of research on sensorimotor integration has used artificial stimuli and simplified behaviors, leaving open questions about nervous system function in the context of natural tasks. Our work investigated mechanisms of dynamic sensorimotor feedback control by analyzing patterns of neural activity in the midbrain superior colliculus (SC) of an echolocating bat tracking and intercepting moving prey. Recordings revealed that sensory and motor neurons comingle within laminae of the SC to support rapid sensorimotor integration. Further, we discovered that neural activity in the bat SC changes with dynamic adaptations in the animal's echolocation behavior. PMID- 29180609 TI - Honokiol Radiosensitizes Squamous Cell Carcinoma of the Head and Neck by Downregulation of Survivin. AB - Purpose: Previous studies revealed diverging results regarding the role of survivin in squamous cell carcinoma of the head and neck (SCCHN). This study aimed to evaluate the clinical significance of survivin expression in SCCHN; the function of survivin in DNA-damage repair following ionizing radiation therapy (RT) in SCCHN cells; and the potential of honokiol to enhance RT through downregulation of survivin.Experimental Design: Expression of survivin in SCCHN patient primary tumor tissues (n = 100) was analyzed and correlated with clinical parameters. SCCHN cell lines were used to evaluate the function of survivin and the effects of honokiol on survivin expression in vitro and in vivoResults: Overexpression of survivin was significantly associated with lymph nodes' metastatic status (P = 0.025), worse overall survival (OS), and disease-free survival (DFS) in patients receiving RT (n = 65, OS: P = 0.024, DFS: P = 0.006) and in all patients with SCCHN (n = 100, OS: P = 0.002, DFS: P = 0.003). In SCCHN cells, depletion of survivin led to increased DNA damage and cell death following RT, whereas overexpression of survivin increased clonogenic survival. RT induced nuclear accumulation of survivin and its molecular interaction with gamma-H2AX and DNA-PKCs. Survivin specifically bound to DNA DSB sites induced by I-SceI endonuclease. Honokiol (which downregulates survivin expression) in combination with RT significantly augmented cytotoxicity in SCCHN cells with acquired radioresistance and inhibited growth in SCCHN xenograft tumors.Conclusions: Survivin is a negative prognostic factor and is involved in DNA-damage repair induced by RT. Targeting survivin using honokiol in combination with RT may provide novel therapeutic opportunities. Clin Cancer Res; 24(4); 858-69. (c)2017 AACR.

AB - BACKGROUND This study was designed to analyze the clinical implications of mycophenolic acid trough concentration monitoring. MATERIAL AND METHODS We collected data of patients with mycophenolic acid trough concentration monitoring after their first kidney transplant between November 2006 and March 2015 who were prescribed tacrolimus, mycophenolate, and methylprednisolone. Analyses were performed on 3 periods: 1 month, 1 month to 1 year, and after 1 year post transplantation. To analyze factors related to acute cellular rejection, logistic regression was used for 1 month, while Cox analysis was used during 1 month to 1 year and after 1 year post-transplantation. RESULTS In the 145 patients receiving mycophenolate mofetil, mean tacrolimus trough >=7.0 ng/mL (OR=0.177, CI=0.060 0.524, p=0.002) and mean mycophenolic acid trough >=1.7 mg/L (OR=0.190, CI=0.040 0.896, p=0.036) were protective for rejection during 1 month. Mean mycophenolic acid trough >=1.7 mg/L (HR=0.179, CI=0.040-0.806, p=0.025) and >=0.7 mg/L (HR=0.142, CI=0.028-0.729, p=0.019) were related to better rejection-free survival during 1 month to 1 year and after 1 year, respectively. In 399 patients receiving enteric-coated mycophenolate sodium, mean tacrolimus trough >=7.0 ng/mL (OR=0.258, CI=0.131-0.507, p<0.001) and mean mycophenolic acid trough >=2.1 mg/L (OR=0.507, CI=0.264-0.973, p=0.041) were protective for rejection during 1 month. Mean mycophenolic acid trough >=1.7 mg/L (HR=0.519, CI=0.289-0.932, p=0.028) and >=0.7 mg/L (HR=0.208, CI=0.072-0.602, p=0.004) were related to better rejection free survival during 1 month to 1 year and after 1 year, respectively. CONCLUSIONS Mycophenolic acid trough concentration monitoring can be useful in preventing acute cellular rejection in patients receiving tacrolimus, mycophenolate, and methylprednisolone. PMID- 29180613 TI - Analysis of Risk Factors for Hypoglycemic Coma in 194 Patients with Type 2 Diabetes. AB - BACKGROUND The present study was conducted to analyze possible risk factors in patients with type 2 diabetes who are in hypoglycemic coma. MATERIAL AND METHODS A total of 194 patients with type 2 diabetic hypoglycemic coma who were admitted to our hospital between January 2010 and January 2016 were included. The patients were all in coma on admission, and their blood glucose levels were lower than 2.8 mmol/L. None of the patients had type I diabetes, specific types of diabetes, or gestational diabetes. Multiple linear regression analysis was used to determine possible factors associated with hypoglycemic coma. RESULTS Among the patients, 82 were male and 112 were female (mean age, 66.88+/-10.62 years). In addition, 72 patients lived in urban areas and 122 lived in rural areas. Occurrence of hypoglycemic coma was correlated with difference between urban and rural residence, glycosylated hemoglobin (HbA1c) level, combined hypertension, and combined neural complications. Self-purchased drugs resulted in significantly lower blood glucose level at the onset of hypoglycemic coma than insulin, secretagogue, or non-secretagogue drugs. Blood glucose level at onset was correlated with season. Patients living in rural areas or with combined macrovascular or microvascular complications had prolonged hospital stay and poor prognosis. CONCLUSIONS Our results demonstrate that rural residence, higher HbA1c level, combined hypertension, and combined neural complications increase the incidence of hypoglycemic coma. Use of self-purchased drugs and colder seasons may result in lower blood glucose levels in patients with hypoglycemic coma. PMID- 29180611 TI - Screening drug effects in patient-derived cancer cells links organoid responses to genome alterations. AB - Cancer drug screening in patient-derived cells holds great promise for personalized oncology and drug discovery but lacks standardization. Whether cells are cultured as conventional monolayer or advanced, matrix-dependent organoid cultures influences drug effects and thereby drug selection and clinical success. To precisely compare drug profiles in differently cultured primary cells, we developed DeathPro, an automated microscopy-based assay to resolve drug-induced cell death and proliferation inhibition. Using DeathPro, we screened cells from ovarian cancer patients in monolayer or organoid culture with clinically relevant drugs. Drug-induced growth arrest and efficacy of cytostatic drugs differed between the two culture systems. Interestingly, drug effects in organoids were more diverse and had lower therapeutic potential. Genomic analysis revealed novel links between drug sensitivity and DNA repair deficiency in organoids that were undetectable in monolayers. Thus, our results highlight the dependency of cytostatic drugs and pharmacogenomic associations on culture systems, and guide culture selection for drug tests.

AB - BACKGROUND Total spondylolisthesis, or dislocation of 1 cervical vertebrae, is only caused by high-energy trauma and is usually fatal. Cervical spine fractures and dislocations often cause 3-column structural damage to the cervical spine, injury to the spinal cord, and precipitating alignment of the cervical vertebrae, as well as cervical instability, which are detrimental, show poor prognosis, and are associated with high rates of mortality rate and disability. CASE REPORT We report an extremely rare case of isolated C5 dislocation caused by falling out of a tree, with sudden tetraplegia. CONCLUSIONS Total spondylolisthesis or dislocation of 1 cervical vertebrae can be surgically treated with anterior approach because it is possible to completely remove the vertebra body, intervertebral disc, and bone fragments, to directly decompress the spinal cord with stabilization. PMID- 29180615 TI - Evolutionary recruitment of flexible Esrp-dependent splicing programs into diverse embryonic morphogenetic processes. AB - Epithelial-mesenchymal interactions are crucial for the development of numerous animal structures. Thus, unraveling how molecular tools are recruited in different lineages to control interplays between these tissues is key to understanding morphogenetic evolution. Here, we study Esrp genes, which regulate extensive splicing programs and are essential for mammalian organogenesis. We find that Esrp homologs have been independently recruited for the development of multiple structures across deuterostomes. Although Esrp is involved in a wide variety of ontogenetic processes, our results suggest ancient roles in non-neural ectoderm and regulating specific mesenchymal-to-epithelial transitions in deuterostome ancestors. However, consistent with the extensive rewiring of Esrp dependent splicing programs between phyla, most developmental defects observed in vertebrate mutants are related to other types of morphogenetic processes. This is likely connected to the origin of an event in Fgfr, which was recruited as an Esrp target in stem chordates and subsequently co-opted into the development of many novel traits in vertebrates. PMID- 29180616 TI - Changes in cortical network connectivity with long-term brain-machine interface exposure after chronic amputation. AB - Studies on neural plasticity associated with brain-machine interface (BMI) exposure have primarily documented changes in single neuron activity, and largely in intact subjects. Here, we demonstrate significant changes in ensemble-level functional connectivity among primary motor cortical (MI) neurons of chronically amputated monkeys exposed to control a multiple-degree-of-freedom robot arm. A multi-electrode array was implanted in M1 contralateral or ipsilateral to the amputation in three animals. Two clusters of stably recorded neurons were arbitrarily assigned to control reach and grasp movements, respectively. With exposure, network density increased in a nearly monotonic fashion in the contralateral monkeys, whereas the ipsilateral monkey pruned the existing network before re-forming a denser connectivity. Excitatory connections among neurons within a cluster were denser, whereas inhibitory connections were denser among neurons across the two clusters. These results indicate that cortical network connectivity can be modified with BMI learning, even among neurons that have been chronically de-efferented and de-afferented due to amputation.

AB - Enhancers and long noncoding RNAs (lncRNAs) are key determinants of lineage specification during development. Here, we evaluate remodeling of the enhancer landscape and modulation of the lncRNA transcriptome during mesendoderm specification. We sort mesendodermal progenitors from differentiating embryonic stem cells (ESCs) according to Eomes expression, and find that enhancer usage is coordinated with mesendoderm-specific expression of key lineage-determining transcription factors. Many of these enhancers are associated with the expression of lncRNAs. Examination of ESC-specific enhancers interacting in three dimensional space with mesendoderm-specifying transcription factor loci identifies MesEndoderm Transcriptional Enhancer Organizing Region (Meteor). Genetic and epigenetic manipulation of the Meteor enhancer reveal its indispensable role during mesendoderm specification and subsequent cardiogenic differentiation via transcription-independent and -dependent mechanisms. Interestingly, Meteor-deleted ESCs are epigenetically redirected towards neuroectodermal lineages. Loci, topologically associating a transcribed enhancer and its cognate protein coding gene, appear to represent therefore a class of genomic elements controlling developmental competence in pluripotency. PMID- 29180619 TI - The STUbL RNF4 regulates protein group SUMOylation by targeting the SUMO conjugation machinery. AB - SUMO-targeted ubiquitin ligases (STUbLs) mediate the ubiquitylation of SUMOylated proteins to modulate their functions. In search of direct targets for the STUbL RNF4, we have developed TULIP (targets for ubiquitin ligases identified by proteomics) to covalently trap targets for ubiquitin E3 ligases. TULIP methodology could be widely employed to delineate E3 substrate wiring. Here we report that the single SUMO E2 Ubc9 and the SUMO E3 ligases PIAS1, PIAS2, PIAS3, ZNF451, and NSMCE2 are direct RNF4 targets. We confirm PIAS1 as a key RNF4 substrate. Furthermore, we establish the ubiquitin E3 ligase BARD1, a tumor suppressor and partner of BRCA1, as an indirect RNF4 target, regulated by PIAS1. Interestingly, accumulation of BARD1 at local sites of DNA damage increases upon knockdown of RNF4. Combined, we provide an insight into the role of the STUbL RNF4 to balance the role of SUMO signaling by directly targeting Ubc9 and SUMO E3 ligases. PMID- 29180617 TI - Transcribed ultraconserved region 339 promotes carcinogenesis by modulating tumor suppressor microRNAs. AB - The transcribed ultraconserved regions (T-UCRs) encode long non-coding RNAs implicated in human carcinogenesis. Their mechanisms of action and the factors regulating their expression in cancers are poorly understood. Here we show that high expression of uc.339 correlates with lower survival in 210 non-small cell lung cancer (NSCLC) patients. We provide evidence from cell lines and primary samples that TP53 directly regulates uc.339. We find that transcribed uc.339 is upregulated in archival NSCLC samples, functioning as a decoy RNA for miR-339-3p, -663b-3p, and -95-5p. As a result, Cyclin E2, a direct target of all these microRNAs is upregulated, promoting cancer growth and migration. Finally, we find that modulation of uc.339 affects microRNA expression. However, overexpression or downregulation of these microRNAs causes no significant variations in uc.339 levels, suggesting a type of interaction for uc.339 that we call "entrapping". Our results support a key role for uc.339 in lung cancer. PMID- 29180620 TI - Quantitative measurement of post-concussion syndrome Using Electrovestibulography. AB - In this study, a noninvasive quantitative measure was used to identify short and long term post-concussion syndrome (PCS) both from each other and from healthy control populations. We used Electrovestibulography (EVestG) for detecting neurophysiological PCS consequent to a mild traumatic brain injury (mTBI) in both short-term (N = 8) and long-term (N = 30) (beyond the normal recovery period) symptomatic individuals. Peripheral, spontaneously evoked vestibuloacoustic signals incorporating - and modulated by - brainstem responses were recorded using EVestG, while individuals were stationary (no movement stimulus). Tested were 38 individuals with PCS in comparison to those of 33 age-and-gender-matched healthy controls. The extracted features were based on the shape of the averaged extracted field potentials (FPs) and their detected firing pattern. Linear discriminant analysis classification, incorporating a leave-one-out routine, resulted in (A) an unbiased 84% classification accuracy for separating healthy controls from a mix of long and short-term symptomatology PCS sufferers and (B) a 79% classification accuracy for separating between long and short-term symptomatology PCS sufferers. Comparatively, short-term symptomatology PCS was generally detected as more distal from controls. Based on the results, the EVestG recording shows promise as an assistive objective tool for detecting and monitoring individuals with PCS after normal recovery periods. PMID- 29180621 TI - Quantitative analysis of intra- and inter-individual variability of human beta cell mass. AB - Pancreatic beta-cell mass is a critical determinant of the progression of diabetes. The loss of beta-cells in various types of diabetes has been documented in comparison to age, sex and body mass index (BMI) matched control subjects. However, the underlying heterogeneity of beta-cell mass in healthy individuals has not been considered. In this study, the inter-individual heterogeneity in beta-cell/islet mass was examined among 10 cases of age-matched non-diabetic male subjects in relation to BMI, pancreas weight, and the percent ratio, volume and number of islets in the whole pancreas. Beta-cell/islet mass was measured using a large-scale unbiased quantification method. In contrast to previous studies, we found no clinically relevant correlation between beta-cell/islet mass and age, BMI or pancreas weight, with large differences in beta-cell/islet mass and islet number among the individuals. Our method extracts the comprehensive information out of individual pancreas providing multifaceted parameters to study the intrinsic heterogeneity of the human pancreas. PMID- 29180622 TI - Calf Circumference as a Novel Tool for Risk of Disability of the Elderly Population. AB - Disability became increasingly common with age, and crude rates of disability were rising around the globe. The aim of this study was to investigate the association between calf circumference (CC) and disability in the U.S. elderly population. From the 1999-2006 National Health and Nutrition Examination Survey, a total of 4,245 participants with an age range of 60-84 years were included. Disability was defined as the total number of difficulties within the following 5 major domains of disability, such as activities of daily living (ADL), instrumental ADL, general physical activities, lower extremity mobility, and leisure and social activities. The association between CC and disability was investigated through the regression model adjusted for multiple covariates. According to the fully adjusted model regarding disability, the beta coefficients for each quartile of increasing CC were -0.041 for quartile 2 (P = 0.096), -0.060 for quartile 3 (P = 0.027), and -0.073 for quartile 4 (P = 0.026) respectively, compared with lowest quartile. There was a negative association between CC and disability among the elderly population. Calf circumference may be a novel risk assessment for disability of elderly people. PMID- 29180623 TI - Genotyping-by-Sequencing Derived High-Density Linkage Map and its Application to QTL Mapping of Flag Leaf Traits in Bread Wheat. AB - Winter wheat parents 'Harry' (drought tolerant) and 'Wesley' (drought susceptible) were used to develop a recombinant inbred population with future goals of identifying genomic regions associated with drought tolerance. To precisely map genomic regions, high-density linkage maps are a prerequisite. In this study genotyping-by- sequencing (GBS) was used to construct the high-density linkage map. The map contained 3,641 markers distributed on 21 chromosomes and spanned 1,959 cM with an average distance of 1.8 cM between markers. The constructed linkage map revealed strong collinearity in marker order across 21 chromosomes with POPSEQ-v2.0, which was based on a high-density linkage map. The reliability of the linkage map for QTL mapping was demonstrated by co-localizing the genes to previously mapped genomic regions for two highly heritable traits, chaff color, and leaf cuticular wax. Applicability of linkage map for QTL mapping of three quantitative traits, flag leaf length, width, and area, identified 21 QTLs in four environments, and QTL expression varied across the environments. Two major stable QTLs, one each for flag leaf length (Qfll.hww-7A) and flag leaf width (Qflw.hww-5A) were identified. The map constructed will facilitate QTL and fine mapping of quantitative traits, map-based cloning, comparative mapping, and in marker-assisted wheat breeding endeavors. PMID- 29180624 TI - Alpha-synuclein facilitates to form short unconventional microtubules that have a unique function in the axonal transport. AB - Although alpha-synuclein (alphaSyn) has been linked to Parkinson's disease (PD), the mechanisms underlying the causative role in PD remain unclear. We previously proposed a model for a transportable microtubule (tMT), in which dynein is anchored to a short tMT by LIS1 followed by the kinesin-dependent anterograde transport; however the mechanisms that produce tMTs have not been determined. Our in vitro investigations of microtubule (MT) dynamics revealed that alphaSyn facilitates the formation of short MTs and preferentially binds to MTs carrying 14 protofilaments (pfs). Live-cell imaging showed that alphaSyn co-transported with dynein and mobile betaIII-tubulin fragments in the anterograde transport. Furthermore, bi-directional axonal transports are severely affected in alphaSyn and gammaSyn depleted dorsal root ganglion neurons. SR-PALM analyses further revealed the fibrous co-localization of alphaSyn, dynein and betaIII-tubulin in axons. More importantly, 14-pfs MTs have been found in rat femoral nerve tissue, and they increased approximately 19 fold the control in quantify upon nerve ligation, indicating the unconventional MTs are mobile. Our findings indicate that alphaSyn facilitates to form short, mobile tMTs that play an important role in the axonal transport. This unexpected and intriguing discovery related to axonal transport provides new insight on the pathogenesis of PD. PMID- 29180625 TI - Differential prognostic value of MYC immunohistochemistry in subtypes of papillary renal cell carcinoma. AB - The histomorphological subtyping of papillary renal cell carcinomas (pRCCs) has improved the predictions of patients' long-term survival. Based on our previous results, we hypothesized that the MYC proto-oncogene would show differential expression in pRCC subtypes. Using a multi-institutional cohort of 204 pRCC patients we assessed the additional value of the immunohistochemical markers MYC, MINA53, and Ki67 in predicting patient's long-term survival. The clinical endpoints were overall survival (OS) and cancer-specific survival (CSS). Nomograms were constructed to predict each patient's risk of death (OS). The incorporation of the MYC staining patterns allowed the stratification of pRCC type 1 patients into better and worse prognostic groups. None of the patients with pRCC type 1 tumors and favorable MYC staining patterns died from tumor related causes. This prognostic value was independent of the patient's age at surgery, the pathological tumor stage and presence of lymph node invasion. we could show that the immunohistochemical assessment of MYC and the histomorphological subtyping of pRCC stratifies pRCC type 1 tumors with regard to OS and CSS. The determination of the histomorphologic pRCC subtype in combination with the MYC immunohistochemical staining patterns allows a more accurate prediction of patients' individual risk of death. PMID- 29180627 TI - Characteristics of martensitic and strain-glass transitions of the Fe-substituted TiNi shape memory alloys probed by transport and thermal measurements. AB - The electrical resistivity, Seebeck coefficient, thermal conductivity, and specific heat of Ti50Ni50-x Fe x (x = 2.0-10.0 at.%) shape memory alloys (SMAs) were measured to investigate the influence of point defects (Fe) on the martensitic transformation characteristics. Our results show that the Ti50Ni48Fe2 and Ti50Ni47Fe3 SMAs have a two-step martensitic transformation (B2 -> R and R -> B19'), while the Ti50Ni46Fe4, Ti50Ni44.5Fe5.5, and Ti50Ni44Fe6 SMAs display a one step martensitic transition (B2 -> R). However, the compounds Ti50Ni42Fe8 and Ti50Ni40Fe10 show strain glass features (frozen strain-ordered state). Importantly, the induced point defects significantly alter the martensitic transformation characteristics, namely transition temperature and width of thermal hysteresis during the transition. This can be explained by the stabilization of austenite B2 phase upon Fe substitution, which ultimately leads to the decrease in enthalpy that associated to the martensitic transition. To determine the boundary composition that separates the R-phase and strain glass systems in this series of SMAs, a Ni-rich specimen Ti49Ni45Fe6 was fabricated. Remarkably, a slight change in Ti/Ni ratio converts Ti49Ni45Fe6 SMA into a strain glass system. Overall, the evolution of phase transformation in the Fe substituted TiNi SMAs is presumably caused by the changes in local lattice structure via the induced local strain fields by Fe point defects. PMID- 29180626 TI - Mitochondrial dynamics controls anti-tumour innate immunity by regulating CHIP IRF1 axis stability. AB - Macrophages, dendritic cells and other innate immune cells are involved in inflammation and host defense against infection. Metabolic shifts in mitochondrial dynamics may be involved in Toll-like receptor agonist-mediated inflammatory responses and immune cell polarization. However, whether the mitochondrial morphology in myeloid immune cells affects anti-tumor immunity is unclear. Here we show that FAM73b, a mitochondrial outer membrane protein, has a pivotal function in Toll-like receptor-regulated mitochondrial morphology switching from fusion to fission. Switching to mitochondrial fission via ablation of Fam73b (also known as Miga2) promotes IL-12 production. In tumor-associated macrophages, this switch results in T-cell activation and enhances anti-tumor immunity. We also show that the mitochondrial morphology affects Parkin expression and its recruitment to mitochondria. Parkin controls the stability of the downstream CHIP-IRF1 axis through proteolysis. Our findings identify mechanisms associated with mitochondrial dynamics that control anti-tumor immune responses and that are potential targets for cancer immunotherapy. PMID- 29180629 TI - Transcriptome profile analysis reveals the regulation mechanism of floral sex differentiation in Jatropha curcas L. AB - The seeds of Jatropha curcas contain a high percentage of biodiesel. However, low seed yield which was limited by its poor female flowers was a bottleneck for its utilization. Here, we compared the transcriptomic profiles of five different samples during floral sex differentiation stages using Illumina Hiseq 4000. Our results showed that hundreds of differentially expressed genes (DEGs) were detected in floral sex initiation period, but thousands of DEGs were involved in the stamens and ovules development process. Moreover, the DEGs were mainly shown up-regulation in male floral initiation, but mainly down-regulation in female floral initiation. Male floral initiation was associated with the flavonoid biosynthesis pathway while female floral initiation was related to the phytohormone signal transduction pathway. Cytokinin (CTK) signaling triggered the initiation of female floral primordium, thereafter other phytohormones co promoted the female floral development. In addition, the floral organ identity genes played important roles in floral sex differentiation process and displayed a general conservation of the ABCDE model in J. curcas. To the best of our knowledge, this data is the first comprehensive analysis of the underlying regulatory mechanism and the related genes during floral sex differentiation in J. curcas, which help in engineering high-yielding varieties of J. curcas. PMID- 29180628 TI - Parkin targets HIF-1alpha for ubiquitination and degradation to inhibit breast tumor progression. AB - Mutations in E3 ubiquitin ligase Parkin have been linked to familial Parkinson's disease. Accumulating evidence suggests that Parkin is a tumor suppressor, but the underlying mechanism is poorly understood. Here we show that Parkin is an E3 ubiquitin ligase for hypoxia-inducible factor 1alpha (HIF-1alpha). Parkin interacts with HIF-1alpha and promotes HIF-1alpha degradation through ubiquitination, which in turn inhibits metastasis of breast cancer cells. Parkin downregulation in breast cancer cells promotes metastasis, which can be inhibited by targeting HIF-1alpha with RNA interference or the small-molecule inhibitor YC 1. We further identify lysine 477 (K477) of HIF-1alpha as a major ubiquitination site for Parkin. K477R HIF-1alpha mutation and specific cancer-associated Parkin mutations largely abolish the functions of Parkin to ubiquitinate HIF-1alpha and inhibit cancer metastasis. Importantly, Parkin expression is inversely correlated with HIF-1alpha expression and metastasis in breast cancer. Our results reveal an important mechanism for Parkin in tumor suppression and HIF-1alpha regulation. PMID- 29180630 TI - ATF4 overexpression induces early onset of hyperlipidaemia and hepatic steatosis and enhances adipogenesis in zebrafish. AB - Activating transcription factor 4 (ATF4) is constitutively expressed in a variety of tissues, and regulates several pathological features associated with metabolic diseases such as non-alcoholic fatty liver diseases (NAFLD) and obesity. However, the role of ATF4 in animal model systems is poorly understood. To investigate ATF4 functions in zebrafish, we conditionally expressed ATF4 proteins, using a Tet-off transgenic system. We observed early-onset hyperlipidaemia and liver steatosis in ATF4 transgenic zebrafish (ATs) without doxycycline treatment (ATs - Dox). Oil Red O (ORO)-stained signals were predominant in the intravascular blood vessels and liver buds of larval ATs - Dox, indicating that ATF4 functionally promotes lipogenesis. Further, ATF4 overexpression accompanied the stimulation of the unfolded protein response. Therefore, adult ATs - Dox showed increased lipid accumulation, which led, in turn, to liver steatosis. Liver histology and ORO staining of ATs - Dox hepatocytes also indicated oxidative stress and induced NASH-like phenotypes. Moreover, ATF4 overexpression accelerated adipocyte differentiation via CCAAT enhancer binding protein-beta and peroxisome proliferator activated receptor-gamma inducible expression. ATs-Dox zebrafish showed increased weight gain with larger fat pads due to adipocyte hyperplasia. In this study, we report that ATF4 is a potential stimulator of lipid biosynthesis and adipogenesis in zebrafish. PMID- 29180631 TI - STRT-seq-2i: dual-index 5' single cell and nucleus RNA-seq on an addressable microwell array. AB - Single-cell RNA-seq has become routine for discovering cell types and revealing cellular diversity, but archived human brain samples still pose a challenge to current high-throughput platforms. We present STRT-seq-2i, an addressable 9600 microwell array platform, combining sampling by limiting dilution or FACS, with imaging and high throughput at competitive cost. We applied the platform to fresh single mouse cortical cells and to frozen post-mortem human cortical nuclei, matching the performance of a previous lower-throughput platform while retaining a high degree of flexibility, potentially also for other high-throughput applications. PMID- 29180632 TI - Microfluidic-assisted Formation of Highly Monodisperse and Mesoporous Silica Soft Microcapsules. AB - The fabrication of mesoporous silica microcapsules with a highly controlled particle size ranging in the micrometer size presents a major challenge in many academic and industrial research areas, such as for the developement of smart drug delivery systems with a well controlled loading and release of (bio)active molecules. Many studies based on the solvent evaporation or solvent diffusion methods have been developed during the last two decades in order to control the particle size, which is often found to range at a sub-micrometer scale. Droplet based microfluidics proved during the last decade a powerful tool to produce highly monodisperse and mesoporous silica solid microspheres with a controllable size in the micrometer range. We show in the present study, in contrast with previous microfluidic-assisted approaches, that a better control of the diffusion of the silica precursor sol in a surrounding perfluorinated oil phase during the silica formation process allows for the formation of highly monodisperse mesoporous silica microcapsules with a diameter ranging in the 10 micrometer range. We show also, using optical, scanning and transmission electron microscopies, small angle x-ray diffraction and BET measurements, that the synthesized mesoporous silica microcapsules exhibit a soft-like thin shell with a thickness of about 1 MUm, across which 5.9 nm sized mesopores form a well-ordered hexagonal 2D network. We suggest and validate experimentally a model where the formation of such microcapsules is controlled by the solvent evaporation process at the droplet-air interface. PMID- 29180633 TI - Integrating evolutionary dynamics into treatment of metastatic castrate-resistant prostate cancer. AB - Abiraterone treats metastatic castrate-resistant prostate cancer by inhibiting CYP17A, an enzyme for testosterone auto-production. With standard dosing, evolution of resistance with treatment failure (radiographic progression) occurs at a median of ~16.5 months. We hypothesize time to progression (TTP) could be increased by integrating evolutionary dynamics into therapy. We developed an evolutionary game theory model using Lotka-Volterra equations with three competing cancer "species": androgen dependent, androgen producing, and androgen independent. Simulations with standard abiraterone dosing demonstrate strong selection for androgen-independent cells and rapid treatment failure. Adaptive therapy, using patient-specific tumor dynamics to inform on/off treatment cycles, suppresses proliferation of androgen-independent cells and lowers cumulative drug dose. In a pilot clinical trial, 10 of 11 patients maintained stable oscillations of tumor burdens; median TTP is at least 27 months with reduced cumulative drug use of 47% of standard dosing. The outcomes show significant improvement over published studies and a contemporaneous population. PMID- 29180634 TI - Transient locking of the hook procures enhanced motility to flagellated bacteria. AB - Flagellated bacteria often proliferate in inhomogeneous environments, such as biofilms, swarms and soil. In such media, bacteria are observed to move efficiently only if they can get out of "dead ends" by changing drastically their swimming direction, and even to completely reverse it. Even though these reorientations are ubiquitous, we have only recently begun to describe and understand how they happen. In the present work, we visualized the flagella of bacteria swimming in a soft agar solution. The surprising observation that the filaments do not rotate while being flipped from one side of the cell to the other suggests that reversals are driven directly by the motor rather than by the thrust created by the rotating filament. This was confirmed by observing bacteria in a liquid crystal, where the linear movement of bacteria greatly simplifies the analysis. These observations suggest that the reversal and reorientation processes involve a temporary locking of the flagellum's hook, which is the normally flexible joint between the rotary motor and the long helical filament that propels the cell. This newly described locked-hook mode occurs only when the motor switches to a clockwise rotation. That correlates with other phenomena that are triggered by a switch in one direction and not the other. PMID- 29180635 TI - Food availability drives plastic self-repair response in a basal metazoan- case study on the ctenophore Mnemiopsis leidyi A. Agassiz 1865. AB - Many marine invertebrates including ctenophores are capable of extensive body regeneration when injured. However, as for the invasive ctenophore Mnemiopsis leidyi, there is a constant subportion of individuals not undergoing whole body regeneration but forming functionally stable half-animals instead. Yet, the driving factors of this phenomenon have not been addressed so far. This study sheds new light on how differences in food availability affect self-repair choice and regeneration success in cydippid larvae of M. leidyi. As expected, high food availability favored whole-body regeneration. However, under low food conditions half-animals became the preferential self-repair mode. Remarkably, both regenerating and half-animals showed very similar survival chances under respective food quantities. As a consequence of impaired food uptake after injury, degeneration of the digestive system would often occur indicating limited energy storage capacities. Taken together, this indicates that half-animals may represent an alternative energy-saving trajectory which implies self-repair plasticity as an adaptive trade-off between high regeneration costs and low energy storage capacities. We conclude that self-repair plasticity could lead to higher population fitness of ctenophores under adverse conditions such as in ships' ballast water tanks which is postulated to be the major vector source for the species' spreading around the globe. PMID- 29180636 TI - Anterior cervical discectomy and fusion surgery versus total disc replacement: A comparative study with minimum of 10-year follow-up. AB - Based on long-term follow-ups, this study was designed to investigate the incidence and risk factors for postoperative adjacent segment degeneration (ASD) after anterior cervical discectomy and fusion (ACDF) or total disc replacement (TDR) in treating cervical degenerative diseases. Between January 2000 and December 2005, 108 cases undergoing ACDF and 78 undergoing TDR, were enrolled into this study. All medical records were retrospectively collected. Every patient was followed up at least 10 years. Outcome assessment included visual analogue scale (VAS) score, Neck Disability Index (NDI) score, Japanese Orthopaedic Association (JOA) score, and radiographic parameters. Consequently, thirty-eight (35.2%) of 108 cases suffered from ASD in ACDF group, and 26 (33.3%) of 78 cases in TDR group. There was no statistical difference between the two groups regarding ASD incidence, VAS/NDI/JOA score, recovery rate. Logistic regression analysis showed that age (OR = 2.86, 95% CI, 1.58-4.14) and preoperative segmental lordosis (OR = 1.90, 95% CI, 1.05-3.20) were risk factors associated with increased odds of ASD regardless of surgical procedures. On the other hand, preoperative overall lordosis (OR = 0.54, 95% CI, 0.26-0.82) was most likely protective. In conclusion, advanced age and preoperative segmental lordosis were identified as risk factors for postoperative ASD, while preoperative overall lordosis proves to be a protective factor. PMID- 29180637 TI - Present and past selves: a steady-state visual evoked potentials approach to self face processing. AB - The self-face has a prioritized status in the processing of incoming visual inputs. As the self-face changes over the lifespan, this stimulus seems to be well-suited for investigation of the self across time. Here, steady-state visual evoked potentials (SSVEP, oscillatory responses to periodic stimulation with a frequency that mirrors the frequency of stimulation) were used to investigate this topic. Different types of faces (present self, past self, close-other's, unknown, scrambled) flickered four times per second in two types of stimulation ('identical', with the same image of a given type of face; 'different', with different images of the same type of face). Each of the 10 stimulation sessions lasted 90 seconds and was repeated three times. EEG data were recorded and analyzed in 20 participants. In general, faces evoked higher SSVEP than scrambled faces. The impact of identical and different stimulation was similar for faces and scrambled faces: SSVEP to different stimuli (faces, scrambled faces) was enhanced in comparison to identical ones. Present self-faces evoked higher SSVEP responses than past self-faces in the different stimulation condition only. Thus, our results showed that the physical aspects of the present and past selves are differentiated on the neural level in the absence of an overt behavior. PMID- 29180638 TI - Clipping has stronger effects on plant production than does warming in three alpine meadow sites on the Northern Tibetan Plateau. AB - The relative effects of warming and clipping on vegetation growth are not fully understood. Therefore, we compared the relative effects of experimental warming and clipping on the normalised difference vegetation index (NDVI), green NDVI (GNDVI), soil-adjusted vegetation index (SAVI), aboveground biomass (AGB) and gross primary production (GPP) in three alpine meadow sites (A, B and C) on the Northern Tibetan Plateau from 2013 to 2015. There were no obvious effects of experimental warming on the NDVI, GNDVI, SAVI, AGB and GPP at the three sites, which were most likely attributed to experimental warming-induced warming and drying conditions. In contrast, clipping significantly decreased the NDVI, SAVI and AGB by 27.8%, 31.3% and 18.2% at site A, by 27.1%, 31.8% and 27.7% at site B, and by 12.3%, 15.1% and 17.6% at site C, respectively. Clipping also significantly reduced the GNDVI and GPP by 11.1% and 28.2% at site A and by 18.9% and 33.7% at site B, respectively. Clipping marginally decreased the GNDVI by 8.7% (p = 0.060) and GPP (p = 0.082) by 14.4% at site C. Therefore, clipping had stronger effects on vegetation growth than did warming in the three alpine meadow sites on the Tibetan Plateau. PMID- 29180639 TI - The chromatin remodeling factor ISW-1 integrates organismal responses against nuclear and mitochondrial stress. AB - Age-associated changes in chromatin structure have a major impact on organismal longevity. Despite being a central part of the ageing process, the organismal responses to the changes in chromatin organization remain unclear. Here we show that moderate disturbance of histone balance during C. elegans development alters histone levels and triggers a stress response associated with increased expression of cytosolic small heat-shock proteins. This stress response is dependent on the transcription factor, HSF-1, and the chromatin remodeling factor, ISW-1. In addition, we show that mitochondrial stress during developmental stages also modulates histone levels, thereby activating a cytosolic stress response similar to that caused by changes in histone balance. These data indicate that histone and mitochondrial perturbations are both monitored through chromatin remodeling and involve the activation of a cytosolic response that affects organismal longevity. HSF-1 and ISW-1 hence emerge as a central mediator of this multi-compartment proteostatic response regulating longevity. PMID- 29180640 TI - Young onset type 2 diabetic patients might be more sensitive to metformin compared to late onset type 2 diabetic patients. AB - It is unknown whether YOD (young onset diabetes) and LOD (late onset diabetes) require similar insulin doses for intensive insulin therapy with a metformin add on to achieve glycemic control. We analyzed data from our two previously performed randomized, controlled open-label trials. Patients were randomized to receive either continuous subcutaneous insulin infusion (CSII) therapy or CSII combined with metformin therapy for 4 weeks. The studies concentrated on the differences in the insulin doses used for the two groups. We included 36 YOD (age < 40 yrs) and 152 LOD (age > 40 yrs) patients. YOD patients who received metformin combined with CSII therapy required significantly lower insulin doses to maintain euglycemic control compared to patients with LOD. A multivariate analysis, controlled for gender and the fasting blood concentration, was performed to determine the significance of the differences between groups, particularly with respect to the total and basal insulin doses. There was a trend toward improvement in beta-cell function and insulin resistance in terms of DeltaHOMA-B and DeltaHOMA-IR in patients with YOD compared to those with LOD. Newly diagnosed T2D patients with YOD required significantly lower insulin doses, particularly basal insulin doses, to maintain glycemic control compared to the LOD patients. PMID- 29180641 TI - A sensitive and rapid immunoassay for Mycoplasma pneumoniae in children with pneumonia based on single-walled carbon nanotubes. AB - Mycoplasma pneumoniae(MP) is a leading pathogen of respiratory infection, especially community-acquired pneumonia (CAP), in children worldwide. However, its diagnosis is frequently ineffective because bacterial culture and serology test are usually positive 1-2 weeks or more after the disease onset. To achieve a better detection efficiency, the single-walled carbon nanotubes(SWCNT) were coupled with the colloidal gold-monoclonal antibody immunochromatographic strips(CGIC). Interestingly, the SWCNT/CGIC assay allowed MP identification, with a detection limit of 1 * 102 copies/ml. Using referenced throat swabs of 97 MP and 40 non-MP cases, the assay yielded 72.2% sensitivity, 100.0% specificity, 100.0% positive predictive value (PPV), 59.7% negative predictive value (NPV). In summary, our assay was far more effective than any conventional methods for the diagnosis of acute MP. The ease of use, rapid and stability further enhance its feasibility for clinical use on-site. PMID- 29180642 TI - A new structural arrangement in proteins involving lysine NH3+ group and carbonyl. AB - Screening of the Protein Data Bank led to identification of a recurring structural motif where lysine NH3+ group interacts with backbone carbonyl. This interaction is characterized by linear atom arrangement, with carbonyl O atom positioned on the three-fold symmetry axis of the NH3+ group (angle Cepsilon Nzeta-O close to 180 degrees , distance Nzeta-O ca. 2.7-3.0 A). Typically, this linear arrangement coexists with three regular hydrogen bonds formed by lysine NH3+ group (angle Cepsilon-Nzeta-acceptor atom close to 109 degrees , distance Nzeta-acceptor atom ca. 2.7-3.0 A). Our DFT calculations using polarizable continuum environment suggest that this newly identified linear interaction makes an appreciable contribution to protein's energy balance, up to 2 kcal/mol. In the context of protein structure, linear interactions play a role in capping the C termini of alpha-helices and 310-helices. Of note, linear interaction involving conserved lysine is consistently found in the P-loop of numerous NTPase domains, where it stabilizes the substrate-binding conformation of the P-loop. Linear interaction NH3+ - carbonyl represents an interesting example of ion-dipole interactions that has so far received little attention compared to ion-ion interactions (salt bridges) and dipole-dipole interactions (hydrogen bonds), but nevertheless represents a distinctive element of protein architecture.

AB - Outdoor fine particulate air pollution (PM2.5) is known to increase mortality risk and is recognized as an important contributor to global disease burden. However, less is known about how oxidant gases may modify the chronic health effects of PM2.5. In this study, we examined how the oxidant capacity of O3 and NO2 (using a redox-weighted average, Ox) may modify the relationship between PM2.5 and mortality in the 2001 Canadian Census Health and Environment Cohort. In total, 2,448,500 people were followed over a 10.6-year period. Each 3.86 ug/m3 increase in PM2.5 was associated with nonaccidental (Hazard Ratio (HR) = 1.095, 95% CI: 1.077, 1.112), cardiovascular (HR = 1.088, 95% CI: 1.059, 1.118), and respiratory mortality (HR = 1.110, 95% CI: 1.051, 1.171) in the highest tertile of Ox whereas weaker/null associations were observed in the middle and lower tertiles. Analysis of joint non-linear concentration-response relationships for PM2.5 and Ox suggested threshold concentrations between approximately 23 and 25 ppb with Ox concentrations above these values strengthening PM2.5-mortality associations. Overall, our findings suggest that oxidant gases enhance the chronic health risks of PM2.5. In some areas, reductions in Ox concentrations may have the added benefit of reducing the public health impacts of PM2.5 even if mass concentrations remain unchanged.

AB - With the recent progress in genome-editing technologies, such as the CRISPR/Cas9 system, genetically modified animals carrying nucleotide substitutions or large chromosomal rearrangements can be produced rapidly and at low cost. Such genome editing techniques have been applied in the generation of animal models, especially mice, for reproducing human disease mutations, such as single nucleotide polymorphisms (SNPs) or large chromosomal rearrangements identified by genome-wide screening analyses. While application methods are under development for various complex mutations involving genome editing for mimicking human disease-causing mutations in mice, functional studies of mouse models carrying replicated human mutations are gradually being published. In this review, we discuss the recent progress in application methods of the CRISPR/Cas9 system, focusing on the production of mouse models of diseases. PMID- 29180646 TI - Phytoplankton communities determine the spatio-temporal heterogeneity of alkaline phosphatase activity: evidence from a tributary of the Three Gorges Reservoir. AB - In order to reveal the role of phytoplankton in the spatio-temporal distribution of alkaline phosphatase activity (APA), monthly investigations were conducted in the Xiaojiang River, a tributary of the Three Gorges Reservoir in China. Different APA fractions, environmental parameters, and phytoplankton communities were followed. High spatio-temporal variations of APA were observed, with the highest value in summer and the lowest in winter. The annual average APAT (total alkaline phosphatase activity) ranged from 7.78-14.03 nmol?L-1?min-1 with the highest in the midstream and the lowest in the estuary. The dominant phytoplankton phyla in summer and winter were Cyanophyta and Bacillariophyta, respectively. The mean cell density in the midstream and in the estuary was 5.2 * 107 cell?L-1 and 1.4 * 107 cell?L-1, respectively. That APA>3.0 MUm was significantly higher than APA0.45-3 MUm indicating phytoplankton was the main contributor to alkaline phosphatase. Correlation analysis indicated the dominant species and cell density could determine the distribution pattern of APA. Turbidity, total phosphorus, chemical oxygen demand, water temperature (WT), pH and chlorophyll a were proved to be positively correlated with APA; soluble reactive phosphorus, conductivity, transparency and water level(WL) were negatively correlated with APA. It was concluded that spatio-temporal heterogeneity of APA determined by phytoplankton communities was related to WT and WL.

AB - Chromosome transfer technology, including chromosome modification, enables the introduction of Mb-sized or multiple genes to desired cells or animals. This technology has allowed innovative developments to be made for models of human disease and humanized animals, including Down syndrome model mice and humanized transchromosomic (Tc) immunoglobulin mice. Genome editing techniques are developing rapidly, and permit modifications such as gene knockout and knockin to be performed in various cell lines and animals. This review summarizes chromosome transfer-related technologies and the combined technologies of chromosome transfer and genome editing mainly for the production of cell/animal models of human disease and humanized animal models. Specifically, these include: (1) chromosome modification with genome editing in Chinese hamster ovary cells and mouse A9 cells for efficient transfer to desired cell types; (2) single nucleotide polymorphism modification in humanized Tc mice with genome editing; and (3) generation of a disease model of Down syndrome-associated hematopoiesis abnormalities by the transfer of human chromosome 21 to normal human embryonic stem cells and the induction of mutation(s) in the endogenous gene(s) with genome editing. These combinations of chromosome transfer and genome editing open up new avenues for drug development and therapy as well as for basic research. PMID- 29180647 TI - Prediction of postoperative outcomes using intraoperative hemodynamic monitoring data. AB - Major surgeries can result in high rates of adverse postoperative events. Reliable prediction of which patient might be at risk for such events may help guide peri- and postoperative care. We show how archiving and mining of intraoperative hemodynamic data in orthotopic liver transplantation (OLT) can aid in the prediction of postoperative 180-day mortality and acute renal failure (ARF), improving upon predictions that rely on preoperative information only. From 101 patient records, we extracted 15 preoperative features from clinical records and 41 features from intraoperative hemodynamic signals. We used logistic regression with leave-one-out cross-validation to predict outcomes, and incorporated methods to limit potential model instabilities from feature multicollinearity. Using only preoperative features, mortality prediction achieved an area under the receiver operating characteristic curve (AUC) of 0.53 (95% CI: 0.44-0.78). By using intraoperative features, performance improved significantly to 0.82 (95% CI: 0.56-0.91, P = 0.001). Similarly, including intraoperative features (AUC = 0.82; 95% CI: 0.66-0.94) in ARF prediction improved performance over preoperative features (AUC = 0.72; 95% CI: 0.50-0.85), though not significantly (P = 0.32). We conclude that inclusion of intraoperative hemodynamic features significantly improves prediction of postoperative events in OLT. Features strongly associated with occurrence of both outcomes included greater intraoperative central venous pressure and greater transfusion volumes.

AB - Many Crohn's disease (CD) patients develop intestinal strictures, which are difficult to prevent and treat. Cationic steroid antimicrobial 13 (CSA13) shares cationic nature and antimicrobial function with antimicrobial peptide cathelicidin. As many functions of cathelicidin are mediated through formyl peptide receptor-like 1 (FPRL1), we hypothesize that CSA13 mediates anti fibrogenic effects via FPRL1. Human intestinal biopsies were used in clinical data analysis. Chronic trinitrobenzene sulfonic acid (TNBS) colitis-associated intestinal fibrosis mouse model with the administration of CSA13 was used. Colonic FPRL1 mRNA expression was positively correlated with the histology scores of inflammatory bowel disease patients. In CD patients, colonic FPRL1 mRNA was positively correlated with intestinal stricture. CSA13 administration ameliorated intestinal fibrosis without influencing intestinal microbiota. Inhibition of FPRL1, but not suppression of intestinal microbiota, reversed these protective effects of CSA13. Metabolomic analysis indicated increased fecal mevalonate levels in the TNBS-treated mice, which were reduced by the CSA13 administration. CSA13 inhibited colonic HMG-CoA reductase activity in an FPRL1-dependent manner. Mevalonate reversed the anti-fibrogenic effect of CSA13. The increased colonic FPRL1 expression is associated with severe mucosal disease activity and intestinal stricture. CSA13 inhibits intestinal fibrosis via FPRL1-dependent modulation of HMG-CoA reductase pathway. PMID- 29180650 TI - A Route to Terahertz Metamaterial Biosensor Integrated with Microfluidics for Liver Cancer Biomarker Testing in Early Stage. AB - Engineered Terahertz (THz) metamaterials presented an unique characteristics for biosensing application due to their accurately tunable resonance frequency, which is in accord with vibrational frequency of some important biomolecules such as cancer biomarker. However, water absorption in THz regime is an obstacle to extend application in trace biomolecules of cancer antibody or antigen. Here, to overcome water absorption and enhance the THz biosensing sensitivity, two kinds of THz metamaterials biosensor integrated with microfluidics were fabricated and used to detect the Alpha fetoprotein (AFP) and Glutamine transferase isozymes II (GGT-II) of liver cancer biomarker in early stage. There were about 19 GHz resonance shift (5 mu/ml) and 14.2 GHz resonance shift (0.02524 MUg/ml) for GGT II and AFP with a two-gap-metamaterial, respectively, which agreed with simulation results. Those results demonstrated the power and usefulness of metamaterial-assisted THz spectroscopy in trace cancer biomarker molecular detection for biological and chemical sensing. Moreover, for a particular cancer biomarker, the sensitivity could be further improved by optimizing the metamaterial structure and decreasing the permittivity of the substrate. This method might be powerful and potential for special recognition of cancer molecules in the early stage. PMID- 29180649 TI - Hepatic protein tyrosine phosphatase receptor gamma links obesity-induced inflammation to insulin resistance. AB - Obesity-induced inflammation engenders insulin resistance and type 2 diabetes mellitus (T2DM) but the inflammatory effectors linking obesity to insulin resistance are incompletely understood. Here, we show that hepatic expression of Protein Tyrosine Phosphatase Receptor Gamma (PTPR-gamma) is stimulated by inflammation in obese/T2DM mice and positively correlates with indices of inflammation and insulin resistance in humans. NF-kappaB binds to the promoter of Ptprg and is required for inflammation-induced PTPR-gamma expression. PTPR-gamma loss-of-function lowers glycemia and insulinemia by enhancing insulin-stimulated suppression of endogenous glucose production. These phenotypes are rescued by re expression of Ptprg only in liver of mice lacking Ptprg globally. Hepatic PTPR gamma overexpression that mimics levels found in obesity is sufficient to cause severe hepatic and systemic insulin resistance. We propose hepatic PTPR-gamma as a link between obesity-induced inflammation and insulin resistance and as potential target for treatment of T2DM. PMID- 29180651 TI - Bidirectional Electron-Transfer in Polypeptides with Various Secondary Structures. AB - The protein-mediated bidirectional electron transfer (ET) is the foundation of protein molecular wire, and plays an important role in the rapid detection of oxo guanine-adenine DNA mismatches by MutY glycosylase. However, the influences of structural transitions on bidirectional ET are still not clear. In this work, the modified through-bond coupling (MTBC) model was further refined to correlate the structural transition and ET rate more quantitatively. With this model, various polyglycine structures (310-helix, alpha-helix, beta-sheets, linear, polyproline helical I and II) were studied to explore the influences of structural transitions on bidirectional ET. It was found that the HOMO-LUMO gaps (DeltaE) in CN (from the carboxyl to amino terminus) direction are much lower than that in opposite direction, except for polypro I. However, with the equal tunneling energy, the differences between bidirectional ET rates are slight for all structures. In structural transitions, we found that the ET rates are not only affected by the Ramachandran angles, but also correlated to the alignment of C = O vectors, the alignment of peptide planes and the rearrangement of other structure factors. The detailed information can be used to rationalize the inhomogeneous ET across different protein structures and design more efficient protein molecular wires. PMID- 29180653 TI - Prevalence and risk factors of secondhand smoke (SHS) exposure among pregnant women in Mongolia. AB - This cross-sectional study investigated the prevalence of smoking and secondhand smoking (SHS) among pregnant women in Darkhan-Uul Province, Mongolia, using urinary cotinine (UC) levels, and clarified the factors related to SHS exposure. It targeted pregnant women who underwent antenatal health check-ups from November 2015 to January 2016. Self-administered questionnaires and urine samples were used to collect data. Using UC levels as the criterion, it was found that the prevalence of smokers (>100 ng/ml) among 493 pregnant women was 11.8%, while SHS exposure (>=5 ng/ml) among nonsmokers was 44.8%. Older and highly educated women had lower odds of SHS exposure (p = 0.006 and 0.002, respectively). Furthermore, nonsmoking pregnant women from homes where smoking was permitted had higher odds of SHS exposure compared to women from homes where smoking was not permitted. These results suggest that community guidance programs, such as home smoking cessation that include families, are necessary. PMID- 29180652 TI - In silico-based screen synergistic drug combinations from herb medicines: a case using Cistanche tubulosa. AB - Neuroinflammation is characterized by the elaborated inflammatory response repertoire of central nervous system tissue. The limitations of the current treatments for neuroinflammation are well-known side effects in the clinical trials of monotherapy. Drug combination therapies are promising strategies to overcome the compensatory mechanisms and off-target effects. However, discovery of synergistic drug combinations from herb medicines is rare. Encouraged by the successfully applied cases we move on to investigate the effective drug combinations based on system pharmacology among compounds from Cistanche tubulosa (SCHENK) R. WIGHT. Firstly, 63 potential bioactive compounds, the related 133 direct and indirect targets are screened out by Drug-likeness evaluation combined with drug targeting process. Secondly, Compound-Target network is built to acquire the data set for predicting drug combinations. We list the top 10 drug combinations which are employed by the algorithm Probability Ensemble Approach (PEA), and Compound-Target-Pathway network is then constructed by the 12 compounds of the combinations, targets, and pathways to unearth the corresponding pharmacological actions. Finally, an integrating pathway approach is developed to elucidate the therapeutic effects of the herb in different pathological features relevant biological processes. Overall, the method may provide a productive avenue for developing drug combination therapeutics. PMID- 29180654 TI - Ellipsoidal mirror for two-dimensional 100-nm focusing in hard X-ray region. AB - Cutting-edge hard X-ray microscopy strongly depends on sophisticated focusing optics and ultrabright X-ray sources at synchrotron-radiation and X-ray free electron laser (XFEL) facilities. These facilities typically provide two dimensional nanofocusing X-ray beams by combining one-dimensional focusing mirrors. However, single-reflecting two-dimensional focusing mirrors with an ellipsoidal surface, which are well-known to possess high efficiency, have limited microfocusing applications. In this paper, we present an ultrahigh precision ellipsoidal mirror for two-dimensional X-ray nanofocusing by overcoming the difficulties faced in the manufacturing process of its aspherical surface, including the surface-processing methods and surface metrology. The developed mirror has nanoscale accuracy, and it achieves focus size of 85 nm * 125 nm (full width at half maximum) using 7-keV X-rays. Two-dimensional focus was demonstrated in the same focal plane by resolving 50-nm test structures by scanning X-ray microscopy using a focusing beam. These achievements represent an important first step toward realizing two-dimensional aspherical mirrors with complex designs, in addition to ultralow loss and unprecedented small focusing property for extensive optical applications in synchrotron-radiation and XFEL facilities as well as in other scientific fields that require ultraprecision optical surfaces. PMID- 29180655 TI - Transition metal binding selectivity in proteins and its correlation with the phylogenomic classification of the cation diffusion facilitator protein family. AB - Divalent d-block metal cations (DDMCs), such as Fe, Zn and Mn, participate in many biological processes. Understanding how specific DDMCs are transported to and within the cell and what controls their binding selectivity to different proteins is crucial for defining the mechanisms of metalloproteins. To better understand such processes, we scanned the RCSB Protein Data Bank, performed a de novo structural-based comprehensive analysis of seven DDMCs and found their amino acid binding and coordination geometry propensities. We then utilized these results to characterize the correlation between metal selectivity, specific binding site composition and phylogenetic classification of the cation diffusion facilitator (CDF) protein family, a family of DDMC transporters found throughout evolution and sharing a conserved structure, yet with different members displaying distinct metal selectivity. Our analysis shows that DDMCs differ, at times significantly, in terms of their binding propensities, and that in each CDF clade, the metal selectivity-related binding site has a unique and conserved sequence signature. However, only limited correlation exists between the composition of the DDMC binding site in each clade and the metal selectivity shown by its proteins. PMID- 29180656 TI - Bactofilin-mediated organization of the ParABS chromosome segregation system in Myxococcus xanthus. AB - In bacteria, homologs of actin, tubulin, and intermediate filament proteins often act in concert with bacteria-specific scaffolding proteins to ensure the proper arrangement of cellular components. Among the bacteria-specific factors are the bactofilins, a widespread family of polymer-forming proteins whose biology is poorly investigated. Here, we study the three bactofilins BacNOP in the rod shaped bacterium Myxococcus xanthus. We show that BacNOP co-assemble into elongated scaffolds that restrain the ParABS chromosome segregation machinery to the subpolar regions of the cell. The centromere (parS)-binding protein ParB associates with the pole-distal ends of these structures, whereas the DNA partitioning ATPase ParA binds along their entire length, using the newly identified protein PadC (MXAN_4634) as an adapter. The integrity of these complexes is critical for proper nucleoid morphology and chromosome segregation. BacNOP thus mediate a previously unknown mechanism of subcellular organization that recruits proteins to defined sites within the cytoplasm, far off the cell poles. PMID- 29180657 TI - The electron-phonon interaction at deep Bi 2 Te3-semiconductor interfaces from Brillouin light scattering. AB - It is shown that the electron-phonon interaction at a conducting interface between a topological insulator thin film and a semiconductor substrate can be directly probed by means of high-resolution Brillouin light scattering (BLS). The observation of Kohn anomalies in the surface phonon dispersion curves of a 50 nm thick Bi2Te3 film on GaAs, besides demonstrating important electron-phonon coupling effects in the GHz frequency domain, shows that information on deep interface electrons can be obtained by tuning the penetration depth of optically generated surface phonons so as to selectively probe the interface region, as in a sort of quantum sonar. PMID- 29180658 TI - Paleoclimatic information recorded in fluid inclusions in halites from Lop Nur, Western China. AB - The homogenization temperature (Th) of primary fluid inclusions in halite can be used for paleoclimate interpretations. Lop Nur, in Central Asia, is an extremely arid zone where large amounts of glauberite were deposited from the late Middle to Late Pleistocene. This deposition was accompanied by formation of large-scale potash-bearing brines. However, quantitative paleotemperature data are still lacking, hindering reconstruction of Quaternary climate conditions and their control over potash formation. We measured the Th of inclusions in halite from the salt field and the top of Upper Pleistocene strata in Lop Nur. The maximum homogenization temperature (Th MAX) of inclusions in halite from the salt field was 41.1 degrees C, consistent with the maximum ambient temperature (43.4 degrees C) in the same period. The Th MAX of inclusions in halite from the Upper Pleistocene strata ranged from 35.6 degrees C to 43 degrees C, where maximum air temperatures may have reached 37.9 degrees C to 45.3 degrees C. The results show that a hot and arid climate prevailed in Lop Nur at the end of the Late Pleistocene. Furthermore, changes of the brine chemical composition due to supply variations instead of climate change, may have caused glauberite deposition to cease at the end of the Late Pleistocene. PMID- 29180659 TI - Cooperative function of Fmp30, Mdm31, and Mdm32 in Ups1-independent cardiolipin accumulation in the yeast Saccharomyces cerevisiae. AB - Cardiolipin (CL) is synthesized from phosphatidic acid (PA) through a series of enzymatic reactions occurring at the mitochondrial inner membrane (MIM). Ups1 Mdm35 mediates PA transfer from the mitochondrial outer membrane (MOM) to the MIM in the yeast Saccharomyces cerevisiae. Deletion of UPS1 leads to a ~80% decrease in the cellular CL level. However, the CL accumulation in ups1? cells is enhanced by the depletion of Ups2, which forms a protein complex with Mdm35 and mediates phosphatidylserine (PS) transfer from the MOM to the MIM for phosphatidylethanolamine (PE) synthesis by a PS decarboxylase, Psd1. In this study, we found that the accumulation of CL in ups1? cells was enhanced by deletion of not only UPS2, but also PSD1 and CHO1 encoding a PS synthase, suggesting that low PE levels in mitochondria were relevant to the enhancement of CL accumulation in ups1? cells. Furthermore, the Ups1-independent and low-level PE-enhanced CL accumulation was shown to depend on the functions of FMP30, MDM31, and MDM32. In addition, the physical interactions of Fmp30 with Mdm31 and Mdm32 were revealed. Thus, when the mitochondrial PE level is reduced, Fmp30, Mdm31, and Mdm32 seem to function cooperatively for the accumulation of CL in a UPS1 independent manner. PMID- 29180660 TI - Preparation of ZnS@In2S3 Core@shell Composite for Enhanced Photocatalytic Degradation of Gaseous o-Dichlorobenzene under Visible Light. AB - In this study, novel ZnS@In2S3 core@shell hollow nanospheres were fabricated by a facile refluxing method for the first time, and the formation mechanism of hollow structure with interior architecture was discussed based on ion-exchange Ostwald ripening. As the photocatalytic material for degradation of gaseous o Dichlorobenzene (o-DCB), the as-synthesized core@shell hollow nanospheres were found to show significantly enhanced catalytic performance for effective separation of photo-generated charges. Moreover, the mechanisms of enhanced activity were elucidated by band alignment and unique configuration. Such photocatalyst would meet the demands for the control of persistent organic pollutant (POPs) in the atmospheric environment. PMID- 29180661 TI - Identification of novel genetic loci GAL3ST4 and CHGB involved in susceptibility to leprosy. AB - Leprosy has long been thought to have a strong genetic component, and so far, only positional cloning and genomewide association studies have been used to study the genetic susceptibility to leprosy,while whole exome sequencing (WES) approach has not yet been applied. In this study, we used WES approach on four leprosy patients and four healthy control relatives from two leprosy families. We found three new susceptible loci of leprosy, one in GAL3ST4 and two in CHGB. We went on to validate the findings of WES using 151 leprosy cases and 226 healthy controls by Sanger sequencing. Stratified by gender, GAL3ST4 was found to be the susceptible gene only for the female population, and CHGB48 and CHGB23 were susceptibile to leprosy for the male population, respectively). Moreover, the gene expression levels of the three susceptible loci were measured by real-time PCR after the stimulation by M. leprae antigens in the PBMC (peripheral blood mononuclear cells) of 69 healthy people. The results showed that the female subjects with high frequent genotype in GAL3ST4 had a fivefold elevated expression. We suggest the polymorphisms in GAL3ST4 in different population are associated with increased risk of leprosy. PMID- 29180662 TI - Longer aftershocks duration in extensional tectonic settings. AB - Aftershocks number decay through time, depending on several parameters peculiar to each seismogenic regions, including mainshock magnitude, crustal rheology, and stress changes along the fault. However, the exact role of these parameters in controlling the duration of the aftershock sequence is still unknown. Here, using two methodologies, we show that the tectonic setting primarily controls the duration of aftershocks. On average and for a given mainshock magnitude (1) aftershock sequences are longer and (2) the number of earthquakes is greater in extensional tectonic settings than in contractional ones. We interpret this difference as related to the different type of energy dissipated during earthquakes. In detail, (1) a joint effect of gravitational forces and pure elastic stress release governs extensional earthquakes, whereas (2) pure elastic stress release controls contractional earthquakes. Accordingly, normal faults operate in favour of gravity, preserving inertia for a longer period and seismicity lasts until gravitational equilibrium is reached. Vice versa, thrusts act against gravity, exhaust their inertia faster and the elastic energy dissipation is buffered by the gravitational force. Hence, for seismic sequences of comparable magnitude and rheological parameters, aftershocks last longer in extensional settings because gravity favours the collapse of the hangingwall volumes. PMID- 29180663 TI - A large and distinct skin impression on the cast of a sauropod dinosaur footprint from Early Cretaceous floodplain deposits, Korea. AB - The occurrence and features of skin impressions in a sauropod footprint, the largest (>50 cm in diameter) reported to date for this taxon, from the Lower Cretaceous Haman Formation (Albian) in Korea are described, and its preservation and paleoenvironmental implications are interpreted. The skin impression-bearing deposits are floodplain sediments formed by sheetflood processes. The large impression is preserved in silty mudstone with microbial lenses and wisps overlying a planar- to cross-laminated and fine-grained sandstone to siltstone bed. The paleoenvironment of the skin impression-bearing deposits is interpreted as a saline sandflat to mudflat where microbial mats can form around lakes or ponds under semi-arid paleoclimatic conditions with alternating wetting and drying intervals. These paleoenvironmental conditions would have permitted the distinct preservation of skin impressions in a dinosaur footprint. The observations here suggest that some sauropod dinosaurs in the Cretaceous had a well-developed polygonal skin texture covering nearly the whole of their foot pads, as seen in modern elephants, which would increase stability when walking on muddy and wet ground. PMID- 29180665 TI - Assessment of Unusual Gigantic Jets observed during the Monsoon season: First observations from Indian Subcontinent. AB - Gigantic Jets are electric discharges from thunderstorm cloud tops to the bottom of ionosphere at ~90 km altitude and electrically connect the troposphere and lower ionosphere. Since their first report in 2002, sporadic observations have been reported from ground and space based observations. Here we report first observations of Gigantic Jets in Indian subcontinent over the Indo-Gangetic plains during the monsoon season. Two storms each produced two jets with characteristics not documented so far. Jets propagated ~37 km up remarkably in ~5 ms with velocity of ~7.4 * 106ms-1 and disappeared within ~40-80 ms, which is faster compared to jets reported earlier. The electromagnetic signatures show that they are of negative polarity, transporting net negative charge of ~17-23 C to the lower ionosphere. One jet had an unusual form observed for the first time, which emerged from the leading edge of a slowly drifting complex convective cloud close to the highest regions at ~17 km altitude. A horizontal displacement of ~10 km developed at ~50 km altitude before connecting to the lower ionosphere. Modeling of these Gigantic jets suggests that Gigantic Jets may bend when initiated at the edge of clouds with misaligned vertical charge distribution. PMID- 29180664 TI - Circulating microparticles in acute diabetic Charcot foot exhibit a high content of inflammatory cytokines, and support monocyte-to-osteoclast cell induction. AB - Circulating microparticles (MPs) are major mediators in cardiovascular complications of type 2 diabetes (T2D); however, their contribution to Charcot foot (CF) disease is not known. Here, we purified and assessed the origin, concentration and content of circulating MPs from 33 individuals: 11 with T2D and acute CF, 11 T2D patients with equivalent neuropathy and 11 non-diabetic controls. First, we demonstrated that there were no differences in the distribution of MPs of endothelial, platelet origin among the 3 groups. However, MPs from leukocytes and monocytes origin were increased in CF patients. Moreover, we demonstrated that monocytes-derived MPs originated more frequently from intermediate and non-classical monocytes in CF patients. Five cytokines (G-CSF, GM-CSF, IL-1-ra, IL-2 and IL-16) were significantly increased in MPs from acute CF patients. Applying ingenuity pathways analysis, we found that those cytokines interacted well and induced the activation of pathways that are involved in osteoclast formation. Further, we treated THP-1 monocytes and monocytes sorted from healthy patients with CF-derived MPs during their differentiation into osteoclasts, which increased their differentiation into multinucleated osteoclast like cells. Altogether, our study suggests that circulating MPs in CF disease have a high content of inflammatory cytokines and could increase osteoclast differentiation in vitro. PMID- 29180666 TI - Methane- and dissolved organic carbon-fueled microbial loop supports a tropical subterranean estuary ecosystem. AB - Subterranean estuaries extend inland into density-stratified coastal carbonate aquifers containing a surprising diversity of endemic animals (mostly crustaceans) within a highly oligotrophic habitat. How complex ecosystems (termed anchialine) thrive in this globally distributed, cryptic environment is poorly understood. Here, we demonstrate that a microbial loop shuttles methane and dissolved organic carbon (DOC) to higher trophic levels of the anchialine food web in the Yucatan Peninsula (Mexico). Methane and DOC production and consumption within the coastal groundwater correspond with a microbial community capable of methanotrophy, heterotrophy, and chemoautotrophy, based on characterization by 16S rRNA gene amplicon sequencing and respiratory quinone composition. Fatty acid and bulk stable carbon isotope values of cave-adapted shrimp suggest that carbon from methanotrophic bacteria comprises 21% of their diet, on average. These findings reveal a heretofore unrecognized subterranean methane sink and contribute to our understanding of the carbon cycle and ecosystem function of karst subterranean estuaries. PMID- 29180668 TI - Regulation of human and mouse telomerase genes by genomic contexts and transcription factors during embryonic stem cell differentiation. AB - Differential regulation of telomerase reverse transcriptase (TERT) genes contribute to distinct aging and tumorigenic processes in humans and mice. To study TERT regulation, we generated mouse embryonic stem cell (ESC) lines containing single-copy bacterial artificial chromosome (BAC) reporters, covering hTERT and mTERT genes and their neighboring loci, via recombinase-mediated BAC targeting. ESC lines with chimeric BACs, in which two TERT promoters were swapped, were also generated. Using these chromatinized BACs, we showed that hTERT silencing during differentiation to embryoid bodies (EBs) and to fibroblast like cells was driven by the human-specific genomic context and accompanied by increases of repressive epigenetic marks, H3K9me3 and H3K27me3, near its promoter. Conversely, the mouse genomic context did not repress TERT transcription until late during differentiation. The hTERT promoter was more active than its mouse counterpart when compared in the same genomic contexts. Mutations of E-box and E2F consensus sites at the promoter had little effect on hTERT transcription in ESCs. However, the mutant promoters were rapidly silenced upon EB differentiation, indicating that transcription factors (TFs) bound to these sites were critical in maintaining hTERT transcription during differentiation. Together, our study revealed a dynamic hTERT regulation by chromatin environment and promoter-bound TFs during ESC differentiation. PMID- 29180667 TI - Rods progressively escape saturation to drive visual responses in daylight conditions. AB - Rod and cone photoreceptors support vision across large light intensity ranges. Rods, active under dim illumination, are thought to saturate at higher (photopic) irradiances. The extent of rod saturation is not well defined; some studies report rod activity well into the photopic range. Using electrophysiological recordings from retina and dorsal lateral geniculate nucleus of cone-deficient and visually intact mice, we describe stimulus and physiological factors that influence photopic rod-driven responses. We find that rod contrast sensitivity is initially strongly reduced at high irradiances, but progressively recovers to allow responses to moderate contrast stimuli. Surprisingly, rods recover faster at higher light levels. A model of rod phototransduction suggests that phototransduction gain adjustments and bleaching adaptation underlie rod recovery. Consistently, exogenous chromophore reduces rod responses at bright background. Thus, bleaching adaptation renders mouse rods responsive to modest contrast at any irradiance. Paradoxically, raising irradiance across the photopic range increases the robustness of rod responses. PMID- 29180669 TI - MYC-containing amplicons in acute myeloid leukemia: Genomic structures, evolution, and transcriptional consequences. AB - Double minutes (dmin), homogeneously staining regions, and ring chromosomes are vehicles of gene amplification in cancer. The underlying mechanism leading to their formation as well as their structure and function in acute myeloid leukemia (AML) remain mysterious. We combined a range of high-resolution genomic methods to investigate the architecture and expression pattern of amplicons involving chromosome band 8q24 in 23 cases of AML (AML-amp). This revealed that different MYC-dmin architectures can coexist within the same leukemic cell population, indicating a step-wise evolution rather than a single event origin, such as through chromothripsis. This was supported also by the analysis of the chromothripsis criteria, that poorly matched the model in our samples. Furthermore, we found that dmin could evolve toward ring chromosomes stabilized by neocentromeres. Surprisingly, amplified genes (mainly PVT1) frequently participated in fusion transcripts lacking a corresponding DNA template. We also detected a significant overexpression of the circular RNA of PVT1 (circPVT1) in AML-amp cases versus AML with a normal karyotype. Our results show that 8q24 amplicons in AML are surprisingly plastic DNA structures with an unexpected association to novel fusion transcripts and circular RNAs.Leukemia accepted article preview online, 28 November 2017. doi:10.1038/leu.2017.337.

AB - Enterovirus 71 (EV71) is the predominant causative pathogen of hand-foot-and mouth disease (HFMD). Contrary to other HFMD-causing enterovirus, EV71 can lead to severe neurological complications, even death. MicroRNAs (miRNAs) are small non-coding RNAs that constitute the largest family of gene regulators participating in numerous biological or pathological processes. We previously reported that miR-16-5p increases with severity of HFMD by investigating the expression patterns of host miRNAs in patients with HFMD. However, the mechanisms by which EV71 induces miR-16-5p expression are not clear, and the interaction between EV71 and miR-16-5p is not yet fully understood. Here, we confirmed EV71 induced expression of miR-16-5p both in vitro and in vivo and show that upregulation of miR-16-5p by EV71 infection may occur at the posttranscriptional level. Moreover, EV71-induced caspase activation facilitates the processing of pri-miR-16-1. We also revealed that miR-16-5p can promote EV71-induced nerve cells apoptosis through activating caspase-3. In addition, we found that miR-16 5p can inhibit EV71 replication. CCNE1 and CCND1, two important cell cycle regulators, play an important role in the suppression of EV71 replication by miR 16-5p. Therefore, miR-16-5p is a positive feedback regulator in EV71-induced apoptosis and a suppressor of virus replication. These results help in understanding the interaction network between miRNA and EV71 infection and provide a potential target for the development of antiviral therapy.

AB - Sub-cortical volumetric differences were associated with attention deficit/hyperactivity disorder (ADHD) in a recent multi-site, mega-analysis of 1713 ADHD persons and 1529 controls. As there was a wide range of effect sizes among the sub-cortical volumes, it is possible that selective neuronal vulnerability has a role in these volumetric losses. To address this possibility, we used data from Allen Brain Atlas to investigate variability in gene expression profiles between subcortical regions of typically developing brains. We tested the hypothesis that the expression of genes in a set of curated ADHD candidate genes and five a priori selected, biological pathways would be associated with the Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) findings. Across the subcortical regions studied by ENIGMA, gene expression profiles for three pathways were significantly correlated with ADHD-associated volumetric reductions: apoptosis, oxidative stress and autophagy. These correlations were strong and significant for children with ADHD, but not for adults. Although preliminary, these data suggest that variability of structural brain anomalies in ADHD can be explained, in part, by the differential vulnerability of these regions to mechanisms mediating apoptosis, oxidative stress and autophagy.

AB - Extracellular ATP is a widespread cell-to-cell signaling molecule in the brain, where it functions as a neuromodulator by activating glia and neurons. Although ATP exerts multiple effects on synaptic plasticity and neuro-glia interactions, as well as in mood disorders, the source and regulation of ATP release remain to be elaborated. Here, we define Calhm2 as an ATP-releasing channel protein based on in vitro and in vivo models. Conventional knockout and conditional astrocyte knockout of Calhm2 both lead to significantly reduced ATP concentrations, loss of hippocampal spine number, neural dysfunction and depression-like behaviors in mice, which can be significantly rescued by ATP replenishment. Our findings identify Calhm2 as a critical ATP-releasing channel that modulates neural activity and as a potential risk factor of depression. PMID- 29180672 TI - The thalamic reticular nucleus in schizophrenia and bipolar disorder: role of parvalbumin-expressing neuron networks and oxidative stress. AB - Growing evidence points to a disruption of cortico-thalamo-cortical circuits in schizophrenia (SZ) and bipolar disorder (BD). Clues for a specific involvement of the thalamic reticular nucleus (TRN) come from its unique neuronal characteristics and neural connectivity, allowing it to shape the thalamo cortical information flow. A direct involvement of the TRN in SZ and BD has not been tested thus far. We used a combination of human postmortem and rodent studies to test the hypothesis that neurons expressing parvalbumin (PV neurons), a main TRN neuronal population, and associated Wisteria floribunda agglutinin labeled perineuronal nets (WFA/PNNs) are altered in SZ and BD, and that these changes may occur early in the course of the disease as a consequence of oxidative stress. In both disease groups, marked decreases of PV neurons (immunoreactive for PV) and WFA/PNNs were observed in the TRN, with no effects of duration of illness or age at onset. Similarly, in transgenic mice with redox dysregulation, numbers of PV neurons and WFA/PNN+PV neurons were decreased in transgenic compared with wild-type mice; these changes were present at postnatal day (P) 20 for PV neurons and P40 for WFA/PNN+PV neurons, accompanied by alterations of their firing properties. These results show profound abnormalities of PV neurons in the TRN of subjects with SZ and BD, and offer support for the hypothesis that oxidative stress may play a key role in impacting TRN PV neurons at early stages of these disorders. We put forth that these TRN abnormalities may contribute to disruptions of sleep spindles, focused attention and emotion processing in these disorders.

AB - Neuronal atrophy and alterations of synaptic structure and function in the medial prefrontal cortex (mPFC) have been implicated in the pathogenesis of depression, but the underlying molecular mechanisms are largely unknown. The protein kinase Mzeta (PKMzeta), a brain-specific atypical protein kinase C isoform, is important for maintaining long-term potentiation and storing memory. In the present study, we explored the role of PKMzeta in mPFC in two rat models of depression, chronic unpredictable stress (CUS) and learned helplessness. The involvement of PKMzeta in the antidepressant effects of conventional antidepressants and ketamine were also investigated. We found that chronic stress decreased the expression of PKMzeta in the mPFC and hippocampus but not in the orbitofrontal cortex. Overexpression of PKMzeta in mPFC prevented the depressive-like and anxiety-like behaviors induced by CUS, and reversed helplessness behaviors. Inhibition of PKMzeta in mPFC by expressing a PKMzeta dominant-negative mutant induced depressive-like behaviors after subthreshold unpredictable stress and increased learned helplessness behavior. Furthermore, stress-induced deficits in synaptic proteins and decreases in dendritic density and the frequency of miniature excitatory postsynaptic currents in the mPFC were prevented by PKMzeta overexpression and potentiated by PKMzeta inhibition in subthreshold stress rats. The antidepressants fluoxetine, desipramine and ketamine increased PKMzeta expression in mPFC and PKMzeta mediated the antidepressant effects of ketamine. These findings identify PKMzeta in mPFC as a critical mediator of depressive-like behavior and antidepressant response, providing a potential therapeutic target in developing novel antidepressants. PMID- 29180676 TI - Greatly enhanced light emission of MoS2 using photonic crystal heterojunction. AB - We present theoretical study on developing a one-dimensional (1D) photonic crystal heterojunction (h-PhC) that consists of a monolayer molybdenum disulfide (MoS2) structure. By employing the transfer matrix method, we obtained the analytical solution of the light absorption and emission of two-dimensional materials in 1D h-PhC. Simultaneously enhancing the light absorption and emission of the medium in multiple frequency ranges is easy as h-PhC has more modes of photon localization than the common photonic crystal. Our numerical results demonstrate that the proposed 1D h-PhC can simultaneously enhance the light absorption and emission of MoS2 and enhance the photoluminescence spectrum of MoS2 by 2-3 orders of magnitude.

AB - This work addresses the mechanics of debonding along copper/epoxy joints featuring patterned interfaces. Engineered surface heterogeneities with enhanced adhesion properties are generated through pulsed laser irradiation. Peel tests are carried out to ascertain the effect of patterns shape and area fraction on the mechanical response. Experimental results are evaluated with the support of three-dimensional finite element simulations based on the use of cohesive surfaces. Results discussion is largely framed in terms of effective peel force and energy absorbed to sever the samples. It is shown that surface heterogeneities act as sites of potential crack pinning able to trigger crack initiation, propagation and arrest. Surface patterns ultimately enable a remarkable increase in the effective peel force and dissipated energy with respect to baseline homogeneous sanded interface.

AB - Long intergenic non-coding RNA 152 (LINC00152) is a recently identified tumor promoting long non-coding RNA. However, the biological functions of LINC00152 in colorectal cancer (CRC) remain unclear and require further research. The aim of the present study is to explore the roles of LINC00152 in cellular function and its possible molecular mechanism. In this study, we discovered that LINC00152 was overexpressed in CRC tissues and negatively related to the survival time of CRC patients. Functional analyses revealed that LINC00152 could promote cell proliferation. Furthermore, LINC00152 could increase the resistance of CRC cells to 5-fluorouracil (5-FU) by suppressing apoptosis. We also discovered that LINC00152 could enhance cell migration and invasion. Mechanistic studies demonstrated that LINC00152 could regulate the expression of NOTCH1 through sponging miR-139-5p and inhibiting its activity from promoting CRC progression and development. Altogether, our work points out a novel LINC00152/miR-139 5p/NOTCH1 regulatory axis in CRC progression and development. PMID- 29180679 TI - Risk of non-cardiac surgery after percutaneous coronary intervention with drug eluting stents. AB - Elective non-cardiac surgery (NCS) should optimally be delayed one year after implantation of a drug-eluting stent (DES). Dual antiplatelet therapy or at least aspirin is recommended to be continued considering the relative risk of stent thrombosis especially during the 4 weeks after DES implantation. However, these recommendations were supported by insufficient evidence. We investigated predictors for postoperative major adverse cardiovascular and cerebral event (MACCE) in 1582 patients undergoing non-cardiac surgery after DES implantation. 96 patients (6.1%) developed postoperative MACCE. In the propensity score-matched analysis, aspirin maintenance was not associated with MACCE (odds ratio [OR] 0.78, 95% confidence interval [CI] 0.48-1.27, P = 0.320) and was associated with increased risk of major bleeding (OR 1.84, 95% CI 1.02-3.32, P = 0.044). When patients who underwent NCS within one month after DES implantation were matched with those who underwent NCS thereafter, the risk of MACCE was higher when surgery was done within 30 days after PCI (OR 2.21, 95% CI 1.05-4.66, P = 0.036). Maintenance of aspirin did not decrease MACCE after NCS in patients with DES and only increased the risk of major bleeding. NCS within one month after DES implantation was associated with higher incidence of MACCE. However, prospective trials are required to validate our results. PMID- 29180680 TI - Functional interplay between the transcription factors USF1 and PDX-1 and protein kinase CK2 in pancreatic beta-cells. AB - Glucose homeostasis is regulated by insulin, which is produced in the beta-cells of the pancreas. The synthesis of insulin is controlled by several transcription factors including PDX-1, USF1 and USF2. Both, PDX-1 and USF1 were identified as substrates for protein kinase CK2. Here, we have analysed the interplay of PDX-1, USF1 and CK2 in the regulation of PDX-1 gene transcription. We found that the PDX 1 promoter is dose-dependently transactivated by PDX-1 and transrepressed by USF1. With increasing glucose concentrations the transrepression of the PDX-1 promoter by USF1 is successively abrogated. PDX-1 binding to its own promoter was not influenced by glucose, whereas USF1 binding to the PDX-1 promoter was reduced. The same effect was observed after inhibition of the protein kinase activity by three different inhibitors or by using a phospho-mutant of USF1. Moreover, phosphorylation of USF1 by CK2 seems to strengthen the interaction between USF1 and PDX-1. Thus, CK2 is a negative regulator of the USF1-dependent PDX-1 transcription. Moreover, upon inhibition of CK2 in primary islets, insulin expression as well as insulin secretion were enhanced without affecting the viability of the cells. Therefore, inhibition of CK2 activity may be a promising approach to stimulate insulin production in pancreatic beta-cells. PMID- 29180681 TI - Subthalamic Nucleus Deep Brain Stimulation Does Not Modify the Functional Deficits or Axonopathy Induced by Nigrostriatal alpha-Synuclein Overexpression. AB - Subthalamic nucleus deep brain stimulation (STN DBS) protects dopaminergic neurons of the substantia nigra pars compacta (SNpc) against 6-OHDA and MPTP. We evaluated STN DBS in a parkinsonian model that displays alpha-synuclein pathology using unilateral, intranigral injections of recombinant adeno-associated virus pseudotype 2/5 to overexpress wildtype human alpha-synuclein (rAAV2/5 alpha-syn). A low titer of rAAV2/5 alpha-syn results in progressive forelimb asymmetry, loss of striatal dopaminergic terminal density and modest loss of SNpc dopamine neurons after eight weeks, corresponding to robust human-Snca expression and no effect on rat-Snca, Th, Bdnf or Trk2. alpha-syn overexpression increased phosphorylation of ribosomal protein S6 (p-rpS6) in SNpc neurons, a readout of trkB activation. Rats received intranigral injections of rAAV2/5 alpha-syn and three weeks later received four weeks of STN DBS or electrode implantation that remained inactive. STN DBS did not protect against alpha-syn-mediated deficits in forelimb akinesia, striatal denervation or loss of SNpc neuron, nor did STN DBS elevate p-rpS6 levels further. ON stimulation, forelimb asymmetry was exacerbated, indicating alpha-syn overexpression-mediated neurotransmission deficits. These results demonstrate that STN DBS does not protect the nigrostriatal system against alpha-syn overexpression-mediated toxicity. Whether STN DBS can be protective in other models of synucleinopathy is unknown. PMID- 29180682 TI - Features of reactive cysteines discovered through computation: from kinase inhibition to enrichment around protein degrons. AB - Large-scale characterisation of cysteine modification is enabling study of the physicochemical determinants of reactivity. We find that location of cysteine at the amino terminus of an alpha-helix, associated with activity in thioredoxins, is under-represented in human protein structures, perhaps indicative of selection against background reactivity. An amino-terminal helix location underpins the covalent linkage for one class of kinase inhibitors. Cysteine targets for S palmitoylation, S-glutathionylation, and S-nitrosylation show little correlation with pKa values predicted from structures, although flanking sequences of S palmitoylated sites are enriched in positively-charged amino acids, which could facilitate palmitoyl group transfer to substrate cysteine. A surprisingly large fraction of modified sites, across the three modifications, would be buried in native protein structure. Furthermore, modified cysteines are (on average) closer to lysine ubiquitinations than are unmodified cysteines, indicating that cysteine redox biology could be associated with protein degradation and degron recognition. PMID- 29180683 TI - Hydrogen gas mediates ascorbic acid accumulation and antioxidant system enhancement in soybean sprouts under UV-A irradiation. AB - The soybean sprout is a nutritious and delicious vegetable that is rich in ascorbic acid (AsA). Hydrogen gas (H2) may have potential applications in the vegetable processing industry. To investigate whether H2 is involved in the regulation of soybean sprouts AsA biosynthesis under UV irradiation, we set 4 different treatments: white light(W), W+HRW, UV-A and UV-A+HRW. The results showed that H2 significantly blocked the UV-A-induced accumulation of ROS, decreased TBARS content and enhanced SOD and APX activity in soybean sprouts. We also observed that the UV-A induced accumulation of AsA was enhanced more intensely when co-treated with HRW. Molecular analyses showed that UV-A+HRW significantly up-regulated AsA biosynthesis and recycling genes compared to UV-A in soybean sprouts. These data demonstrate that the H2 positively regulates soybean sprouts AsA accumulation under UV-A and that this effect is mediated via the up-regulation of AsA biosynthesis and recycling genes. PMID- 29180684 TI - Systemic clearance and brain distribution of carbazole-based cyanine compounds as Alzheimer's disease drug candidates. AB - SLM and SLOH, two analogues of carbazole-based cyanine compounds, have been shown to inhibit beta-amyloid peptide aggregation in vitro and in Alzheimer's disease model mice, which could be potentially developed into drugs for disease treatment. To pave the way for further pharmacokinetics-pharmacodynamics study, we set to investigate these compounds' systemic clearance pathways and their brain exposure. We found that they generally exhibited relatively low plasma clearance which comprised of hepatic clearance and biliary clearance. Phase I oxidative metabolites for SLM and for SLOH upon microsomes incubation were identified, and the metabolism by CYP3A4 were found to be the major (>70%) hepatic clearance pathway, while the efflux by P-gp and BCRP located in the canalicular membrane of hepatocytes led to high biliary clearance. The permeation of SLM and SLOH through the brain endothelium was affected by the efflux transporters (P-gp and BCRP) and influx transporter (OATP2B1). The unbound interstitial fluid to plasma ratio (K puu,brain) was 8.10 for SLOH and 11.0 for SLM, which favored brain entry and were several folds higher than that in wild type mice. Taken together, these carbazole compounds displayed low plasma clearance and high brain permeability, which entitle further development. PMID- 29180685 TI - Evaluating the effect of Clostridium difficile conditioned medium on fecal microbiota community structure. AB - Clostridium difficile infection (CDI) is typically associated with disturbed gut microbiota and changes related to decreased colonization resistance against C. difficile are well described. However, nothing is known about possible effects of C. difficile on gut microbiota restoration during or after CDI. In this study, we have mimicked such a situation by using C. difficile conditioned medium of six different C. difficile strains belonging to PCR ribotypes 027 and 014/020 for cultivation of fecal microbiota. A marked decrease of microbial diversity was observed in conditioned medium of both tested ribotypes. The majority of differences occurred within the phylum Firmicutes, with a general decrease of gut commensals with putative protective functions (i.e. Lactobacillus, Clostridium_XIVa) and an increase in opportunistic pathogens (i.e. Enterococcus). Bacterial populations in conditioned medium differed between the two C. difficile ribotypes, 027 and 014/020 and are likely associated with nutrient availability. Fecal microbiota cultivated in medium conditioned by E. coli, Salmonella Enteritidis or Staphylococcus epidermidis grouped together and was clearly different from microbiota cultivated in C. difficile conditioned medium suggesting that C. difficile effects are specific. Our results show that the changes observed in microbiota of CDI patients are partially directly influenced by C. difficile.

AB - Laccases are polyphenol oxidases with widespread applications in various industries. In the present study, the laccase from Cerrena sp. HYB07 was immobilized with four methods, namely entrapment in alginate, covalently binding to chitosan as well as formation of cross-linked enzyme aggregates (CLEAs) and magnetic CLEAs (M-CLEAs). The activity recovery rates of the immobilized laccases ranged from 29% to 68%. Immobilization elevated the reaction temperature optimum and reduced substrate specificity, but not necessarily the turnover rate. pH stability of immobilized laccases was improved compared with that of the free laccase, especially at acidic pH values. Thermal inactivation of all laccases followed a simple first-order exponential decay model, and immobilized laccases displayed higher thermostability, as manifested by lower thermal inactivation rate constants and longer enzyme half-life time. Operational stability of the immobilized laccase was demonstrated by decolorization of the triphenylmethane dye malachite green (MG) at 60 degrees C. MG decolorization with free laccase was accompanied by a shift of the absorption peak and accumulation of a stable, colored intermediate tetradesmethyl MG, probably due to lower thermostability of the free laccase and premature termination of the degradation pathway. In contrast, complete decolorization of MG was achieved with laccase CLEAs at 60 degrees C. PMID- 29180687 TI - Exploring Voluntary Vaccinating Behaviors using Evolutionary N-person Threshold Games. AB - Understanding individuals' voluntary vaccinating behaviors plays essential roles in making vaccination policies for many vaccinepreventable diseases. Usually, individuals decide whether to vaccinate through evaluating the relative cost of vaccination and infection according to their own interests. Mounting evidence shows that the best vaccine coverage level for the population as a whole can hardly be achieved due to the effects of herd immunity. In this paper, taking into consideration the herd immunity threshold, we present an evolutionary N person threshold game, where individuals can dynamically adjust their vaccinating strategies and their payoffs depend nonlinearly on whether or not the herd immunity threshold is reached. First, in well-mixed populations, we analyze the relationships at equilibrium among the fraction of vaccinated individuals, the population size, the basic reproduction number and the relative cost of vaccination and infection. Then, we carry out simulations on four types of complex networks to explore the evolutionary dynamics of the N-person threshold game in structured populations. Specifically, we investigate the effects of disease severity and population structure on the vaccine coverage for different relative costs of vaccination and infection. The results and findings can offer new insight into designing incentive-based vaccination policies for disease intervention and control. PMID- 29180689 TI - A new A-P compartment boundary and organizer in holometabolous insect wings. AB - Decades of research on the highly modified wings of Drosophila melanogaster has suggested that insect wings are divided into two Anterior-Posterior (A-P) compartments separated by an axis of symmetry. This axis of symmetry is created by a developmental organizer that establishes symmetrical patterns of gene expression that in turn pattern the A-P axis of the wing. Butterflies possess more typical insect wings and butterfly wing colour patterns provide many landmarks for studies of wing structure and development. Using eyespot colour pattern variation in Vanessa butterflies, here we show an additional A-P axis of symmetry running between wing sectors 3 and 4. Boundaries of Drosophila mitotic clones suggest the existence of a previously undetected Far-Posterior (F-P) compartment boundary that coincides with this additional A-P axis. A similar compartment boundary is evident in butterfly mosaic gynandromorphs. We suggest that this additional compartment boundary and its associated developmental organizer create an axis of wing colour pattern symmetry and a gene expression based combinatorial code, permitting each insect wing compartment to acquire a unique identity and allowing for the individuation of butterfly eyespots. PMID- 29180688 TI - Involvement of cecropin B in the formation of the Aedes aegypti mosquito cuticle. AB - In this study, we found a mosquito antimicrobial peptide (AMP), Aedes aegypti cecropin B (Aacec B), was expressed constitutively in pupae. Knockdown in the pupae of Aacec B using double-stranded RNA (dsRNA) resulted in high mortality, the emergence of deformed adults and an impairment of pharate adult cuticle formation with fewer lamellae being deposited and the helicoidal pattern of the chitin microfibrils being disorganized. Simultaneous injection of Aacec B dsRNA and Aacec B peptide into pupae significantly reduced this mortality and no deformed adults then emerged. The expression levels of Ae. aegypti prophenoloxidase (AaPPO) 3 and AaPPO 4 were significantly reduced in the Aacec B knockdown pupae. Exogenous Aacec B peptide significantly enhanced the transcription of AaPPO 3 in pupae. Knockdown of AaPPO 3 in pupae caused effects similar to Aacec B-knockdown. The Aacec B peptide could be detected in both the cytoplasm and nuclei of pupal cells and was able to bind to the TTGG(A/C)A motif in AaPPO 3 DNA both in vitro and in vivo. These findings suggest that Aacec B plays a crucial role in pharate adult cuticle formation via the regulation of AaPPO 3 gene expression in pupae. PMID- 29180691 TI - Serum Uric Acid is Independently Associated with Enlarged Perivascular Spaces. AB - Enlarged perivascular spaces (EPVS) are reported to be associated with impaired cognitive function and sleep disorders. It is of clinical importance to understand the risk factors for EPVS. Hyperuricemia increases the risk of hypertension and endothelial dysfunction, which are well recognized to be associated with EPVS. Therefore, we postulated that serum uric acid (SUA) might be associated with EPVS. A total of 665 lacunar stroke patients were enrolled in this study. The SUA concentrations of patients with severe EPVS were much higher than those of patients with mild EPVS (for basal ganglia: 5.25 +/- 1.40 mg/dl vs. 4.75 +/- 1.40 mg/dl, p < 0.001; for white matter: 5.31 +/- 1.41 mg/dl vs. 4.88 +/ 1.37 mg/dl, p = 0.009). The percentage of subjects with severe EPVS tended to be higher in the highest quartile of SUA (chi-square test: P = 0.002 for basal ganglia and 0.006 for white matter). Spearman correlation analysis indicated that the SUA concentrations were positively correlated with the severity of EPVS (rho > 0, p < 0.05). Multivariate logistic regression analysis showed that high normal SUA was independently associated with a higher severity of EPVS. This finding suggests that high SUA levels might be an independent risk factor for EPVS in lacunar stroke patients. PMID- 29180690 TI - FAD104, a regulator of adipogenesis, is a novel suppressor of TGF-beta-mediated EMT in cervical cancer cells. AB - Epithelial-to-mesenchymal transition (EMT) is a biological process in which epithelial cells translate into a mesenchymal phenotype with invasive capacities, contributing to tumour progression, metastasis, and the acquisition of chemotherapy resistance. To identify new therapeutic targets for cancers, it is important to clarify the molecular mechanism of induction of EMT. We have previously reported that fad104, a positive regulator of adipocyte differentiation, suppressed the invasion and metastasis of melanoma and breast cancer cells. In this study, we showed that FAD104 functions as a novel suppressor of transforming growth factor-beta (TGF-beta)-mediated EMT in cervical cancer cells. Expression of FAD104 is upregulated during TGF-beta-mediated EMT in human cervical cancer HeLa cells. Reduction of fad104 expression enhanced TGF beta-mediated EMT and migration in HeLa cells. Conversely, overexpression of FAD104 suppressed TGF-beta-induced EMT. In addition, we showed that FAD104 negatively regulated phosphorylation of Smad2 and Smad3 but positively regulated phosphorylation of Smad1/5/8 via treatment with TGF-beta. These findings demonstrate that FAD104 is a novel suppressor of TGF-beta signalling and represses TGF-beta-mediated EMT in cervical cancer cells. PMID- 29180692 TI - Baicalein ameliorates TNBS-induced colitis by suppressing TLR4/MyD88 signaling cascade and NLRP3 inflammasome activation in mice. AB - Baicalein (5,6,7-trihydroxyflavone), a predominant bioactive component isolated from the root of Scutellaria baicalensis Georgi, has established potent anti inflammatory activity via multi-targeted mechanisms. However, little is known about the effect of baicalein on 2,4,6-trinitrobenzene sulfonic acid (TNBS) induced colitis, which shares pathology related to human Crohn's disease (CD). The present study demonstrated that baicalein alleviated the severity of TNBS induced colitis in mice by decreasing the activity of myeloperoxidase (MPO) and the expression of pro-inflammatory mediators. The decline in the activation of nuclear factor-kappa B (NF-kappaB) and p38 mitogen-activated protein kinase (MAPK) correlated with a decrease in the expression of mucosal toll-like receptor 4 (TLR4) and its adaptor myeloid differentiation factor 88 (MyD88). In vitro, baicalein down-regulated the TLR4/MyD88 signaling cascades (NF-kappaB and MAPKs) in lipopolysaccharide (LPS)-stimulated macrophages. At the upstream level, baicalein bound to the hydrophobic region of the myeloid differentiation protein 2 (MD-2) pocket and inhibited the formation of the LPS-induced MD-2/TLR4 complex. Furthermore, baicalein reduced NOD-like receptor 3 (NLRP3) inflammasome activation and downstream interleukin-1beta expression in a dose-dependent manner. Our study provided evidence for the first time that baicalein attenuated TNBS-induced colitis, at least in part, via inhibition of TLR4/MyD88 signaling cascade as well as inactivation of NLRP3 inflammasome. PMID- 29180693 TI - Anomalous Growth Rate of Ag Nanocrystals Revealed by in situ STEM. AB - In situ microscopy of colloidal nanocrystal growth offers a unique opportunity to acquire direct and straightforward data for assessing classical growth models. Here, we observe the growth trajectories of individual Ag nanoparticles in solution using in situ scanning transmission electron microscopy. For the first time, we provide experimental evidence of growth rates of Ag nanoparticles in the presence of Pt in solution that are significantly faster than predicted by Lifshitz-Slyozov-Wagner theory. We attribute these observed anomalous growth rates to the synergistic effects of the catalytic properties of Pt and the electron beam itself. Transiently reduced Pt atoms serve as active sites for Ag ions to grow, thereby playing a key role in controlling the growth kinetics. Electron beam illumination greatly increases the local concentration of free radicals, thereby strongly influencing particle growth rate and the resulting particle morphology. Through a systematic investigation, we demonstrate the feasibility of utilizing these synergistic effects for controlling the growth rates and particle morphologies at the nanoscale. Our findings not only expand the current scope of crystal growth theory, but may also lead to a broader scientific application of nanocrystal synthesis. PMID- 29180694 TI - Anions for Near-Infrared Selective Organic Salt Photovoltaics. AB - Organic molecular salts are an emerging and highly tunable class of materials for organic and transparent photovoltaics. In this work, we demonstrate novel phenyl borate and carborane-based anions paired with a near-infrared (NIR)-selective heptamethine cation. We further explore the effects of anion structures and functional groups on both device performance and physical properties. Changing the functional groups on the anion significantly alters the open circuit voltage and yields a clear dependence on electron withdrawing groups. Anion exchange is also shown to selectively alter the solubility and film surface energy of the resulting molecular salt, enabling the potential fabrication of solution deposited cascade or multi-junction devices from orthogonal solvents. This study further expands the catalog and properties of organic salts for inexpensive, and stable NIR-selective molecular salt photovoltaics. PMID- 29180695 TI - The interactive effects of arbuscular mycorrhiza and plant growth-promoting rhizobacteria synergistically enhance host plant defences against pathogens. AB - Belowground interactions between plant roots, mycorrhizal fungi and plant growth promoting rhizobacteria (PGPR) can improve plant health via enhanced nutrient acquisition and priming of the plant immune system. Two wheat cultivars differing in their ability to form mycorrhiza were (co)inoculated with the mycorrhizal fungus Rhizophagus irregularis and the rhizobacterial strain Pseudomonas putida KT2440. The cultivar with high mycorrhizal compatibility supported higher levels of rhizobacterial colonization than the low compatibility cultivar. Those levels were augmented by mycorrhizal infection. Conversely, rhizobacterial colonization of the low compatibility cultivar was reduced by mycorrhizal arbuscule formation. Single inoculations with R. irregularis or P. putida had differential growth effects on both cultivars. Furthermore, while both cultivars developed systemic priming of chitosan-induced callose after single inoculations with R. irregularis or P. putida, only the cultivar with high mycorrhizal compatibility showed a synergistic increase in callose responsiveness following co-inoculation with both microbes. Our results show that multilateral interactions between roots, mycorrhizal fungi and PGPR can have synergistic effects on growth and systemic priming of wheat.

AB - The structural and electronic properties of stanene/hexagonal boron nitride (Sn/h BN) heterobilayer with different stacking patterns are studied using first principle calculations within the framework of density functional theory. The electronic band structure of different stacking patterns shows a direct band gap of ~30 meV at Dirac point and at the Fermi energy level with a Fermi velocity of ~0.53 * 106 ms-1. Linear Dirac dispersion relation is nearly preserved and the calculated small effective mass in the order of 0.05mo suggests high carrier mobility. Density of states and space charge distribution of the considered heterobilayer structure near the conduction and the valence bands show unsaturated pi orbitals of stanene. This indicates that electronic carriers are expected to transport only through the stanene layer, thereby leaving the h-BN layer to be a good choice as a substrate for the heterostructure. We have also explored the modulation of the obtained band gap by changing the interlayer spacing between h-BN and Sn layer and by applying tensile biaxial strain to the heterostructure. A small increase in the band gap is observed with the increasing percentage of strain. Our results suggest that, Sn/h-BN heterostructure can be a potential candidate for Sn-based nanoelectronics and spintronic applications.

Sophia is one of the most problematic weed species infesting winter wheat in China, and has evolved high resistance to tribenuron-methyl. Amino acid substitutions at site of Pro197, Asp376 and Trp574 in acetohydroxyacid synthase (AHAS) were mainly responsible for D. sophia resistance to tribenuron-methyl. In this study, D. sophia plant individually homozygous for specific AHAS mutation (Pro197Leu, Pro197His, Pro197Ser, Pro197Thr, Asp376Glu and Trp574Leu) were generated. In addition, the effects of resistance mutations on pigments, growths and competitiveness of susceptible (S) and resistant (R) plants of D. sophia were investigated. The results indicated the R plants carrying Pro197Leu or Pro197His or Asp376Glu or Trp574Leu displayed stronger competitiveness than S plants. The adverse effects on R plants aggravated with the increase of R plants proportion, which made the R plants against domination the weed community in absent of herbicide selection. Therefore, these resistance mutation have no obvious adverse effects on the pigments (chlorophyll a, chlorophyll b and carotenoid), relative growth rates (RGR), leaf area ratio (LAR) and net assimilation rate (NAR) of R plants. PMID- 29180698 TI - Dual impact of elevated temperature on plant defence and bacterial virulence in Arabidopsis. AB - Environmental conditions profoundly affect plant disease development; however, the underlying molecular bases are not well understood. Here we show that elevated temperature significantly increases the susceptibility of Arabidopsis to Pseudomonas syringae pv. tomato (Pst) DC3000 independently of the phyB/PIF thermosensing pathway. Instead, elevated temperature promotes translocation of bacterial effector proteins into plant cells and causes a loss of ICS1-mediated salicylic acid (SA) biosynthesis. Global transcriptome analysis reveals a major temperature-sensitive node of SA signalling, impacting ~60% of benzothiadiazole (BTH)-regulated genes, including ICS1 and the canonical SA marker gene, PR1. Remarkably, BTH can effectively protect Arabidopsis against Pst DC3000 infection at elevated temperature despite the lack of ICS1 and PR1 expression. Our results highlight the broad impact of a major climate condition on the enigmatic molecular interplay between temperature, SA defence and function of a central bacterial virulence system in the context of a widely studied susceptible plant pathogen interaction. PMID- 29180700 TI - Autophagy protects pancreatic beta cell mass and function in the setting of a high-fat and high-glucose diet. AB - Autophagy is a major regulator of pancreatic beta cell homeostasis. Altered autophagic activity has been implicated in the beta cells of patients with type 2 diabetes, and in the beta cells of obese diabetic rodents. Here, we show that autophagy was induced in beta cells by either a high-fat diet or a combined high fat and high-glucose diet, but not by high-glucose alone. However, a high-glucose intake alone did increase beta cell mass and insulin secretion moderately. Depletion of Atg7, a necessary component of the autophagy pathway, in beta cells by pancreatic intra-ductal AAV8-shAtg7 infusion in C57BL/6 mice, resulted in decreased beta cell mass, impaired glucose tolerance, defective insulin secretion, and increased apoptosis when a combined high-fat and high-glucose diet was given, seemingly due to suppression of autophagy. Taken together, our findings suggest that the autophagy pathway may act as a protective mechanism in pancreatic beta cells during a high-calorie diet. PMID- 29180699 TI - Mutant-IDH1-dependent chromatin state reprogramming, reversibility, and persistence. AB - Mutations in IDH1 and IDH2 (encoding isocitrate dehydrogenase 1 and 2) drive the development of gliomas and other human malignancies. Mutant IDH1 induces epigenetic changes that promote tumorigenesis, but the scale and reversibility of these changes are unknown. Here, using human astrocyte and glioma tumorsphere systems, we generate a large-scale atlas of mutant-IDH1-induced epigenomic reprogramming. We characterize the reversibility of the alterations in DNA methylation, the histone landscape, and transcriptional reprogramming that occur following IDH1 mutation. We discover genome-wide coordinate changes in the localization and intensity of multiple histone marks and chromatin states. Mutant IDH1 establishes a CD24+ population with a proliferative advantage and stem-like transcriptional features. Strikingly, prolonged exposure to mutant IDH1 results in irreversible genomic and epigenetic alterations. Together, these observations provide unprecedented high-resolution molecular portraits of mutant-IDH1 dependent epigenomic reprogramming. These findings have substantial implications for understanding of mutant IDH function and for optimizing therapeutic approaches to targeting IDH-mutant tumors. PMID- 29180701 TI - Longitudinal study of visual field changes determined by Humphrey Field Analyzer 10-2 in patients with Retinitis Pigmentosa. AB - The aim of this study is to determine the progress of the visual field defects obtained by the Humphrey Field Analyzer 10-2 program (HFA 10-2) in patients with retinitis pigmentosa (RP). The medical records of 45 eyes of 45 RP patients who had at least 3 visual field tests were reviewed. Linear mixed models were used to follow the changes of the mean deviation and the average sensitivity of 4, 12, and 20 points in three concentric squares, designated as S4, S12, and S20. The median follow-up time was 3.86 years [range: 1.93 to 9.86, IQR (Interquartile range): 3.01 to 4.93]. The median number of the visual field tests was 3 (range: 3 to 15, IQR: 3 to 4). The mean change of the MD was -0.46 dB/year (-5.80%/year). When the patients were grouped by the average initial MD, the less advanced group had slower progressions than the more advanced group in S4, S12, and S20. These results should be useful in understanding the pathological changes of RP in the central visual field. PMID- 29180702 TI - Developing a Machine Learning System for Identification of Severe Hand, Foot, and Mouth Disease from Electronic Medical Record Data. AB - Children of severe hand, foot, and mouth disease (HFMD) often present with same clinical features as those of mild HFMD during the early stage, yet later deteriorate rapidly with a fulminant disease course. Our goal was to: (1) develop a machine learning system to automatically identify cases with high risk of severe HFMD at the time of admission; (2) compare the effectiveness of the new system with the existing risk scoring system. Data on 2,532 HFMD children admitted between March 2012 and July 2015, were collected retrospectively from a medical center in China. By applying a holdout strategy and a 10-fold cross validation method, we developed four models with the random forest algorithm using different variable sets. The prediction system HFMD-RF based on the model of 16 variables from both the structured and unstructured data, achieved 0.824 sensitivity, 0.931 specificity, 0.916 accuracy, and 0.916 area under the curve in the independent test set. Most remarkably, HFMD-RF offers significant gains with respect to the commonly used pediatric critical illness score in clinical practice. As all the selected risk factors can be easily obtained, HFMD-RF might prove to be useful for reductions in mortality and complications of severe HFMD. PMID- 29180703 TI - Comparison of graphical optimization or IPSA for improving brachytheraphy plans associated with inadequate target coverage for cervical cancer. AB - Many studies have reported that inverse planning by simulated annealing (IPSA) can improve the quality of brachytherapy plans, and we wanted to examine whether IPSA could improve cervical cancer brachytherapy plans giving D90 < 6 Gy (with 7 Gy per fraction) at our institution. Various IPSA plans involving the tandem and ovoid applicators were developed for 30 consecutive cervical cancer patients on the basis of computed tomography: IPSA1, with a constraint on the maximum dose in the target volume; IPSA1-0, identical to IPSA1 but without a dwell-time deviation constraint; IPSA2, without a constraint on the maximum dose; and IPSA2-0, identical to IPSA2 but without a dwell-time deviation constraint. IPSA2 achieved similar results as graphical optimization, and none of the other IPSA plans was significantly better than graphical optimization. Therefore, other approaches, such as combining interstitial and intracavitary brachytherapy, may be more appropriate for improving the quality of brachytherapy plans associated with inadequate target coverage. PMID- 29180705 TI - Rapid morphological change of a top predator with the invasion of a novel prey. AB - Invasive exotic species are spreading rapidly throughout the planet. These species can have widespread impacts on biodiversity, yet the ability for native species, particularly long-lived vertebrates, to respond rapidly to invasions remains mostly unknown. Here we provide evidence of rapid morphological change in the endangered snail kite (Rostrhamus sociabilis) across its North American range with the invasion of a novel prey, the island apple snail (Pomacea maculata), a much larger congener of the kite's native prey. In less than one decade since invasion, snail kite bill size and body mass increased substantially. Larger bills should be better suited to extracting meat from the larger snail shells, and we detected strong selection on increased size through juvenile survival. Using pedigree data, we found evidence of both genetic and environmental influences on trait expression and discovered that additive genetic variation in bill size increased with invasion. However, trends in predicted breeding values emphasize that recent morphological changes have been driven primarily by phenotypic plasticity rather than micro-evolutionary change. Our findings suggest that evolutionary change may be imminent and underscore that even long-lived vertebrates can respond quickly to invasive species. Furthermore, these results highlight that phenotypic plasticity may provide a crucial role for predators experiencing rapid environmental change. PMID- 29180704 TI - Vps34 PI 3-kinase inactivation enhances insulin sensitivity through reprogramming of mitochondrial metabolism. AB - Vps34 PI3K is thought to be the main producer of phosphatidylinositol-3 monophosphate, a lipid that controls intracellular vesicular trafficking. The organismal impact of systemic inhibition of Vps34 kinase activity is not completely understood. Here we show that heterozygous Vps34 kinase-dead mice are healthy and display a robustly enhanced insulin sensitivity and glucose tolerance, phenotypes mimicked by a selective Vps34 inhibitor in wild-type mice. The underlying mechanism of insulin sensitization is multifactorial and not through the canonical insulin/Akt pathway. Vps34 inhibition alters cellular energy metabolism, activating the AMPK pathway in liver and muscle. In liver, Vps34 inactivation mildly dampens autophagy, limiting substrate availability for mitochondrial respiration and reducing gluconeogenesis. In muscle, Vps34 inactivation triggers a metabolic switch from oxidative phosphorylation towards glycolysis and enhanced glucose uptake. Our study identifies Vps34 as a new drug target for insulin resistance in Type-2 diabetes, in which the unmet therapeutic need remains substantial. PMID- 29180707 TI - Flow regime alteration degrades ecological networks in riparian ecosystems. AB - Riverine ecosystems are governed by patterns of temporal variation in river flows. This dynamism will change due to climate change and the near-ubiquitous human control of river flows globally, which may have severe effects on species distributions and interactions. We employed a combination of population modelling and network theory to explore the consequences of possible flow regime futures on riparian plant communities, including scenarios of increased drought, flooding and flow homogenization (removal of flow variability). We found that even slight modifications to the historic natural flow regime had significant consequences for the structure of riparian plant networks. Networks of emergent interactions between plant guilds were most connected at the natural flow regime and became simplified with increasing flow alteration. The most influential component of flow alteration was flood reduction, with drought and flow homogenization both having greater simplifying community-wide consequences than increased flooding. These findings suggest that maintaining floods under future climates will be needed to overcome the negative long-term consequences of flow modification on riverine ecosystems. PMID- 29180708 TI - Outstanding research opportunities at the interface of evolution and medicine. PMID- 29180709 TI - Predation drives local adaptation of phenotypic plasticity. AB - Phenotypic plasticity is the ability of an individual genotype to alter aspects of its phenotype depending on the current environment. It is central to the persistence, resistance and resilience of populations facing variation in physical or biological factors. Genetic variation in plasticity is pervasive, which suggests its local adaptation is plausible. Existing studies on the adaptation of plasticity typically focus on single traits and a few populations, while theory about interactions among genes (for example, pleiotropy) suggests that a multi-trait, landscape scale (for example, multiple populations) perspective is required. We present data from a landscape scale, replicated, multi-trait experiment using a classic predator-prey system centred on the water flea Daphnia pulex. We find predator regime-driven differences in genetic variation of multivariate plasticity. These differences are associated with strong divergent selection linked to a predation regime. Our findings are evidence for local adaptation of plasticity, suggesting that responses of populations to environmental variation depend on the conditions in which they evolved in the past. PMID- 29180706 TI - Complexity and conservation of regulatory landscapes underlie evolutionary resilience of mammalian gene expression. AB - To gain insight into how mammalian gene expression is controlled by rapidly evolving regulatory elements, we jointly analysed promoter and enhancer activity with downstream transcription levels in liver samples from 15 species. Genes associated with complex regulatory landscapes generally exhibit high expression levels that remain evolutionarily stable. While the number of regulatory elements is the key driver of transcriptional output and resilience, regulatory conservation matters: elements active across mammals most effectively stabilize gene expression. In contrast, recently evolved enhancers typically contribute weakly, consistent with their high evolutionary plasticity. These effects are observed across the entire mammalian clade and are robust to potential confounders, such as the gene expression level. Using liver as a representative somatic tissue, our results illuminate how the evolutionary stability of gene expression is profoundly entwined with both the number and conservation of surrounding promoters and enhancers. PMID- 29180710 TI - Biodiversity-multifunctionality relationships depend on identity and number of measured functions. AB - Biodiversity ensures ecosystem functioning and provisioning of ecosystem services, but it remains unclear how biodiversity-ecosystem multifunctionality relationships depend on the identity and number of functions considered. Here, we demonstrate that ecosystem multifunctionality, based on 82 indicator variables of ecosystem functions in a grassland biodiversity experiment, increases strongly with increasing biodiversity. Analysing subsets of functions showed that the effects of biodiversity on multifunctionality were stronger when more functions were included and that the strength of the biodiversity effects depended on the identity of the functions included. Limits to multifunctionality arose from negative correlations among functions and functions that were not correlated with biodiversity. Our findings underline that the management of ecosystems for the protection of biodiversity cannot be replaced by managing for particular ecosystem functions or services and emphasize the need for specific management to protect biodiversity. More plant species from the experimental pool of 60 species contributed to functioning when more functions were considered. An individual contribution to multifunctionality could be demonstrated for only a fraction of the species. PMID- 29180711 TI - Global patterns in marine predatory fish. AB - Large teleost (bony) fish are a dominant group of predators in the oceans and constitute a major source of food and livelihood for humans. These species differ markedly in morphology and feeding habits across oceanic regions; large pelagic species such as tunas and billfish typically occur in the tropics, whereas demersal species of gadoids and flatfish dominate boreal and temperate regions. Despite their importance for fisheries and the structuring of marine ecosystems, the underlying factors determining the global distribution and productivity of these two groups of teleost predators are poorly known. Here, we show how latitudinal differences in predatory fish can essentially be explained by the inflow of energy at the base of the pelagic and benthic food chain. A low productive benthic energy pathway favours large pelagic species, whereas equal productivities support large demersal generalists that outcompete the pelagic specialists. Our findings demonstrate the vulnerability of large teleost predators to ecosystem-wide changes in energy flows and hence provide key insight to predict the responses of these important marine resources under global change. PMID- 29180712 TI - Colour discrimination thresholds in type 1 Bipolar Disorder: a pilot study. AB - Although some studies have reported perceptual changes in psychosis, no definitive conclusions have been drawn about visual disturbances that are related to bipolar disorder (BPD). The purpose of the present study was to evaluate colour vision in BPD patients. Data were recorded from 24 participants: healthy control group (n = 12) and type 1 BPD group (n = 12). The participants were 20-45 years old and they were free from neurological disorders and identifiable ocular disease and had normal or corrected-to-normal visual acuity. Colour discrimination was evaluated using the Lanthony D-15d, Trivector and Ellipse tests, using a psychophysical forced-choice method. The relationship of visual measures to mood state and cognitive function was also investigated. The results showed that BPD patients had higher colour discrimination thresholds in the D15d (p < 0.001), Trivector (p < 0.001) and Ellipse (p < 0.01) tests compared with healthy controls. Linear regression analysis showed that mood state was related to colour discrimination. BPD individuals were not impaired in cognitive tasks. The present study provided new evidence of potential links between type 1 BPD and visual processing impairments. This research suggests a new direction for studies and the need for research in this field of study. PMID- 29180713 TI - Metabolic regulatory oscillations in intertidal green seaweed Ulva lactuca against tidal cycles. AB - The survival of wetland plant species largely relies on physiological adaptations essential for submergence and desiccation. Intertidal seaweeds, unlike terrestrial plants, have unique adaptations to submergence and can also sustain desiccation arising from tidal rhythms. This study determined the differential metabolic regulations in the inter-tidal seaweed species Ulva lactuca against the submergence and desiccation. During desiccation, the relative water content of the algal thalli declined with concomitant increase in reactive oxygen species (ROS) and lipid peroxidation. Nevertheless, the trends reversed during recovery on re-submergence and attained homeostasis. Metabolite profiling of U. lactuca revealed desiccation induced balance in energy reserve utilization by adjusting carbohydrate metabolism and switch over to ammonia metabolism. Upon re submergence, thalli showed an increase in fermentative metabolites, pyruvate alanine conversion, and the GABA shunt. Prolonged submergence induced substrate level phosphorylation mediated sugar biosynthesis while continuing the alternative carbon flux through fermentative metabolism, an increase in osmoprotectants glycine and betaine, sulfur bearing compounds cysteine and hypotaurine, and phenolic compound coniferaldehyde. The determined metabolic regulations in U. lactuca for submergence tolerance provide insights into potential evolutionarily conserved protective mechanisms across the green lineage and also highlights the possible role of sulfur oxoforms as strong free radical scavengers. PMID- 29180714 TI - Unraveling the molecular mechanism of photosynthetic toxicity of highly fluorescent silver nanoclusters to Scenedesmus obliquus. AB - While the discovery of numerous attractive properties of silver at the nanoscale has increased their demand in many sectors including medicine, optics, sensing, painting and cosmetics, it has also raised wide public concerns about their effect on living organisms in aquatic environment. Despite the continuous effort to understand the various aspects of the toxicity of silver nanomaterials, the molecular level understanding on their cytotoxicity mechanism to biological organisms has remained unclear. Herein, we demonstrated the underlying mechanism of the photosynthetic toxicity against green algae namely, Scenedesmus obliquus by using an emerging silver nanomaterial, called silver nanoclusters (defined as r-Ag NCs). By exploiting the unique fluorescence properties of r-Ag NCs along with various other analytical/biological tools, we proposed that the photosynthetic toxicity of r-Ag NCs was largely attributed to the "joint toxicity" effect of particulate form of r-Ag NCs and its released Ag+, which resulted in the disruption of the electron transport chain of light reaction and affected the content of key enzymes (RuBP carboxylase/ oxygenase) of Calvin cycle of algae cells. We believe that the present study can also be applied to the assessment of the ecological risk derived from other metal nanoparticles. PMID- 29180715 TI - A PLGA-reinforced PEG in situ gel formulation for improved sustainability of hypoglycaemic activity of glimepiride in streptozotocin-induced diabetic rats. AB - Glimepiride (GMD) is a third-generation sulfonylurea derivative and one of the top three most-prescribed oral antidiabetic drugs. The need for a depot formulation exists, and a safe and effective antidiabetic therapy is the goal of this study. The aims were to design a depot in situ gel (ISG) formulation and investigate the main factors that control the initial burst and sustain the GMD effect using the Box-Behnken design. The studied factors were polymer percent (X1), plasticizer percent (X2) and benzyl benzoate percent in N-methyl-2 pyrrolidone (X3). The results revealed that X2 is the only factor that showed significant effects on all investigated responses. Scanning electron microscopy images showed that an increase in PEG % improved the smoothness and reduced the porosity of the ISG formulation surface. The GMD plasma levels in diabetic rats revealed no significant difference (p < 0.05) between the maximum GMD plasma concentrations of the optimized GMD-ISG formula (10 mg/ kg) and oral marketed GMD tablets (1 mg/kg). This result ensures that the optimized formula does not exceed the maximum safe plasma concentration. In addition, the optimized GMD-ISG formulation showed a depot effect that lasted for 14 days post-injection. This approach to controlling GMD release using an in situ forming system could be useful for improving patient compliance and diabetes treatment effectiveness. PMID- 29180716 TI - Drosophila Kruppel homolog 1 represses lipolysis through interaction with dFOXO. AB - Transcriptional coordination is a vital process contributing to metabolic homeostasis. As one of the key nodes in the metabolic network, the forkhead transcription factor FOXO has been shown to interact with diverse transcription co-factors and integrate signals from multiple pathways to control metabolism, oxidative stress response, and cell cycle. Recently, insulin/FOXO signaling has been implicated in the regulation of insect development via the interaction with insect hormones, such as ecdysone and juvenile hormone. In this study, we identified an interaction between Drosophila FOXO (dFOXO) and the zinc finger transcription factor Kruppel homolog 1 (Kr-h1), one of the key players in juvenile hormone signaling. We found that Kr-h1 mutants show delayed larval development and altered lipid metabolism, in particular induced lipolysis upon starvation. Notably, Kr-h1 physically and genetically interacts with dFOXO in vitro and in vivo to regulate the transcriptional activation of insulin receptor (InR) and adipose lipase brummer (bmm). The transcriptional co-regulation by Kr h1 and dFOXO may represent a broad mechanism by which Kruppel-like factors integrate with insulin signaling to maintain metabolic homeostasis and coordinate organism growth. PMID- 29180717 TI - Three-year monitoring of genetic diversity reveals a micro-connectivity pattern and local recruitment in the broadcast marine species Paracentrotus lividus. AB - In conservation and management of marine biological resources, a knowledge of connectivity is necessary to understand how local populations are naturally replenished by the arrival of new recruits from source populations. At small geographical scales, species experiencing moderate to long pelagic larval phases are mostly genetically homogeneous, which hinders inferences about local connectivity. Recent studies demonstrated that assessing genetic relatedness and kinship could provide information about local connectivity in populations with high levels of gene flow. Here, we were interested in deciphering the structure and connectivity of populations of the sea urchin Paracentrotus lividus, by monitoring populations at 11 localities distributed along a 225-km coast-line in the south-eastern French Mediterranean Sea. Using 12 microsatellite loci, we found a weak but significant genetic differentiation and observed a transient genetic differentiation among locations within temporal cohorts, without any correlation with the distance between locations, interpreted as unexplainable chaotic genetic patchiness. Among temporal cohorts, the more related individuals were mainly found within locations and the observed local differentiation (FST) correlated with the proportion of kin within locations, suggesting that larvae dispersed cohesively. Specifically, we could also reveal that populations flanking Cape Sicie were influenced by eastern populations and that local recruitment was a frequent occurrence. Overall, our results contribute to the growing number of studies showing that connectivity can be reliably assessed at a fine spatial scale even in genetically homogenous populations. PMID- 29180718 TI - Efficiency of genomic prediction of non-assessed single crosses. AB - An important application of genomic selection in plant breeding is predicting untested single crosses (SCs). Most investigations on the prediction efficiency were based on tested SCs using cross-validation. The main objective was to assess the prediction efficiency by correlating the predicted and true genotypic values of untested SCs (accuracy) and measuring the efficacy of identification of the best 300 untested SCs (coincidence) using simulated data. We assumed 10,000 SNPs, 400 QTLs, two groups of 70 selected DH lines, and 4900 SCs. The heritabilities for the assessed SCs were 30, 60, and 100%. The scenarios included three sampling processes of DH lines, two sampling processes of SCs for testing, two SNP densities, DH lines from distinct and the same populations, DH lines from populations with lower LD, two genetic models, three statistical models, and three statistical approaches. We derived a model for genomic prediction based on SNP average effects of substitution and dominance deviations. The prediction accuracy is not affected by the linkage phase. The prediction of untested SCs is very efficient. The accuracies and coincidences ranged from ~0.8 and 0.5 at low heritability to 0.9 and 0.7 at high heritability, respectively. We also highlight the relevance of the overall LD and demonstrate that efficient prediction of untested SCs can be achieved for crops that show no heterotic pattern, for reduced training set size (10%), for SNP density of 1 cM, and for distinct sampling processes of DH lines based on random choice of the SCs for testing. PMID- 29180719 TI - Population mitogenomics provides insights into evolutionary history, source of invasions and diversifying selection in the House Crow (Corvus splendens). AB - The House Crow (Corvus splendens) is a useful study system for investigating the genetic basis of adaptations underpinning successful range expansion. The species originates from the Indian subcontinent, but has successfully spread through a variety of thermal environments across Asia, Africa and Europe. Here, population mitogenomics was used to investigate the colonisation history and to test for signals of molecular selection on the mitochondrial genome. We sequenced the mitogenomes of 89 House Crows spanning four native and five invasive populations. A Bayesian dated phylogeny, based on the 13 mitochondrial protein-coding genes, supports a mid-Pleistocene (~630,000 years ago) divergence between the most distant genetic lineages. Phylogeographic patterns suggest that northern South Asia is the likely centre of origin for the species. Codon-based analyses of selection and assessments of changes in amino acid properties provide evidence of positive selection on the ND2 and ND5 genes against a background of purifying selection across the mitogenome. Protein homology modelling suggests that four amino acid substitutions inferred to be under positive selection may modulate coupling efficiency and proton translocation mediated by OXPHOS complex I. The identified substitutions are found within native House Crow lineages and ecological niche modelling predicts suitable climatic areas for the establishment of crow populations within the invasive range. Mitogenomic patterns in the invasive range of the species are more strongly associated with introduction history than climate. We speculate that invasions of the House Crow have been facilitated by standing genetic variation that accumulated due to diversifying selection within the native range. PMID- 29180720 TI - SNX27 links DGKzeta to the control of transcriptional and metabolic programs in T lymphocytes. AB - Sorting nexin 27 (SNX27) recycles PSD-95, Dlg1, ZO-1 (PDZ) domain-interacting membrane proteins and is essential to sustain adequate brain functions. Here we define a fundamental SNX27 function in T lymphocytes controlling antigen-induced transcriptional activation and metabolic reprogramming. SNX27 limits the activation of diacylglycerol (DAG)-based signals through its high affinity PDZ interacting cargo DAG kinase zeta (DGKzeta). SNX27 silencing in human T cells enhanced T cell receptor (TCR)-stimulated activator protein 1 (AP-1)- and nuclear factor kappaB (NF-kappaB)-mediated transcription. Transcription did not increase upon DGKzeta silencing, suggesting that DGKzeta function is dependent on SNX27. The enhanced transcriptional activation in SNX27-silenced cells contrasted with defective activation of the mammalian target of rapamycin (mTOR) pathway. The analysis of Snx27 -/- mice supported a role for SNX27 in the control of T cell growth. This study broadens our understanding of SNX27 as an integrator of lipid based signals with the control of transcription and metabolic pathways. PMID- 29180721 TI - 5D proteomic approach for the biomarker search in plasma: Acute myeloid leukaemia as a case study. AB - Acute myeloid leukaemia (AML) is a type of cancer affecting all ages but it is more common in adults, as compared to children. Recent advancements in proteomics and mass spectrometry tools, offer a comprehensive solution to study the molecular complexity of diseases, such as cancers. This study is focused on the proteomic profiling of AML in comparison to healthy control for which, a systematic 5D proteomic approach for the fractionation of pooled plasma samples was used. Methodology includes depletion of Top-7 abundant proteins, ZOOM isoelectric focusing (ZOOM-IEF), two-dimensional gel electrophoresis (2-DGE), and matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) analysis followed by the validation of identified biomarker proteins using enzyme linked immunosorbent assay (ELISA). Up-/down-fold changes in concentration of proteins were observed in 2-DGE of AML in comparison with the healthy control and a total of 34 proteins were identified in fractioned plasma. Among them, fifteen proteins were significantly differentiated and five proteins; SAA1, complement factor C7, ApoE, plasminogen, and ApoA1 were later verified by ELISA in individual samples, which showed that SAA1 and plasminogen could be used as potential biomarker for AML. PMID- 29180722 TI - Rare non-coding variants are associated with plasma lipid traits in a founder population. AB - Founder populations are ideally suited for studies on the clinical effects of alleles that are rare in general populations but occur at higher frequencies in these isolated populations. Whole genome sequencing in 98 Hutterites, a founder population of European descent, and subsequent imputation revealed 660,238 single nucleotide polymorphisms that are rare (<1%) or absent in European populations, but occur at frequencies >1% in the Hutterites. We examined the effects of these rare in European variants on plasma lipid levels in 828 Hutterites and applied a Bayesian hierarchical framework to prioritize potentially causal variants based on functional annotations. We identified two novel non-coding rare variants associated with LDL cholesterol (rs17242388 in LDLR) and HDL cholesterol (rs189679427 between GOT2 and APOOP5), and replicated previous associations of a splice variant in APOC3 (rs138326449) with triglycerides and HDL-C. All three variants are at well-replicated loci in GWAS but are independent from and have larger effect sizes than the known common variation in these regions. Candidate eQTL analyses in in LCLs in the Hutterites suggest that these rare non-coding variants are likely to mediate their effects on lipid traits by regulating gene expression. PMID- 29180723 TI - Neuromodulation of orexin neurons reduces diet-induced adiposity. AB - BACKGROUND/OBJECTIVES: Low levels of orexin are associated with obesity and reduced physical activity in humans and animals. SUBJECTS/METHODS: Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) selectively activated orexin neurons in mouse lateral hypothalamus (LH) to measure effects on spontaneous physical activity (SPA). DREADD targeting was achieved by stereotaxic injection of AAV vectors into caudal lateral LH of heterozygous orexin-Cre or C57/B6J mice. In one set of studies, excitation of orexin neurons was examined (virus: AAV2-EF1a-DIO-hM3Dq-mCherry), and test sessions began 3-4 h after light cycle onset. In a study examining the inhibition of orexin neurons (virus: AAV2 hSyn-DIO-hM4Di-mCherry), testing began 15 min prior to dark cycle onset. Clozapine n-oxide (CNO; 1 or 5 mg/kg) or saline was injected intraperitoneally and time spent moving in open field chambers was recorded for 2 h. Follow-up studies in separate mouse cohorts quantified SPA in parallel with changes in energy expenditure (EE) and chow intake using indirect calorimetry chambers (SableSystemTM). Following acclimation, testing sessions (saline and/or CNO) took place over the course of ~1 week, with injections administered every day. Changes in SPA, EE, chow intake, fecal boli, and body composition (EchoMRITM) were measured. Additional mice cohorts were fed a high-fat diet (HFD) and injected with CNO daily up to 10 days to assess the potential for orexin activation to prevent diet-induced obesity. RESULTS: Activation of orexin resulted in increases in SPA in male and female mice, and was accompanied by increases in energy expenditure without changes in overall chow intake. When orexin activation occurred in the context of high fat diet, weight gain and adiposity were significantly attenuated. SPA was decreased when DREADDs were used to inhibit orexin activity. CONCLUSION: These results demonstrate that orexin neurons play a critical role in mediating physical activity and suggest a novel therapeutic target for treating obesity. PMID- 29180724 TI - Novel Common Variants Associated with Obesity and Type 2 Diabetes Detected Using a cFDR Method. AB - Genome-wide association studies (GWASs) have been performed extensively in diverse populations to identify single nucleotide polymorphisms (SNPs) associated with complex diseases or traits. However, to date, the SNPs identified fail to explain a large proportion of the variance of the traits/diseases. GWASs on type 2 diabetes (T2D) and obesity are generally focused on individual traits independently, and genetic intercommunity (common genetic contributions or the product of over correlated phenotypic world) between them are largely unknown, despite extensive data showing that these two phenotypes share both genetic and environmental risk factors. Here, we applied a recently developed genetic pleiotropic conditional false discovery rate (cFDR) approach to discover novel loci associated with BMI and T2D by incorporating the summary statistics from existing GWASs of these two traits. Conditional Q-Q and fold enrichment plots were used to visually demonstrate the strength of pleiotropic enrichment. Adopting a cFDR nominal significance level of 0.05, 287 loci were identified for BMI and 75 loci for T2D, 23 of which for both traits. By incorporating related traits into a conditional analysis framework, we observed significant pleiotropic enrichment between obesity and T2D. These findings may provide novel insights into the etiology of obesity and T2D, individually and jointly. PMID- 29180727 TI - Cancer immunotherapy: Rewiring cancer cells.

AB - Vibrio cholerae colonizes the human terminal ileum to cause cholera, and the arthropod intestine and exoskeleton to persist in the aquatic environment. Attachment to these surfaces is regulated by the bacterial quorum-sensing signal transduction cascade, which allows bacteria to assess the density of microbial neighbours. Intestinal colonization with V. cholerae results in expenditure of host lipid stores in the model arthropod Drosophila melanogaster. Here we report that activation of quorum sensing in the Drosophila intestine retards this process by repressing V. cholerae succinate uptake. Increased host access to intestinal succinate mitigates infection-induced lipid wasting to extend survival of V. cholerae-infected flies. Therefore, quorum sensing promotes a more favourable interaction between V. cholerae and an arthropod host by reducing the nutritional burden of intestinal colonization.

AB - Antibiotic exposure in children has been associated with the risk of inflammatory bowel disease (IBD). Antibiotic use in children or in their pregnant mother can affect how the intestinal microbiome develops, so we asked whether the transfer of an antibiotic-perturbed microbiota from mothers to their children could affect their risk of developing IBD. Here we demonstrate that germ-free adult pregnant mice inoculated with a gut microbial community shaped by antibiotic exposure transmitted their perturbed microbiota to their offspring with high fidelity. Without any direct or continued exposure to antibiotics, this dysbiotic microbiota in the offspring remained distinct from controls for at least 21 weeks. By using both IL-10-deficient and wild-type mothers, we showed that both inoculum and genotype shape microbiota populations in the offspring. Because IL10 /- mice are genetically susceptible to colitis, we could assess the risk due to maternal transmission of an antibiotic-perturbed microbiota. We found that the IL10-/- offspring that had received the perturbed gut microbiota developed markedly increased colitis. Taken together, our findings indicate that antibiotic exposure shaping the maternal gut microbiota has effects that extend to the offspring, with both ecological and long-term disease consequences.

AB - The genesis of large igneous provinces (LIP) is controlled by multiple factors including anomalous mantle temperatures, the presence of fusible fertile components and volatiles in the mantle source, and the extent of decompression. The lack of a comprehensive examination of all these factors in one specific LIP makes the mantle plume model debatable. Here, we report estimates of the water content in picrites from the Emeishan LIP in southwestern China. Although these picrites display an island arc-like H2O content (up to 3.4 by weight percent), the trace element characteristics do not support a subduction zone setting but point to a hydrous reservoir in the deep mantle. Combining with previous studies, we propose that hydrous and hot plumes occasionally appeared in the Phanerozoic era to produce continental LIPs (e.g., Tarim, Siberian Trap, Karoo). The wide sampling of hydrous reservoirs in the deep mantle by mantle plumes thus indicates that the Earth's interior is largely hydrated.

AB - Ion transport behaviour of halogen-free hybrid electrolytes for lithium-ion batteries based on phosphonium bis(salicylato)borate [P4,4,4,8][BScB] ionic liquid mixed with diethylene glycol dibutyl ether (DEGDBE) is investigated. The Li[BScB] salt is dissolved at different concentrations in the range from 0.15 mol kg-1 to 1.0 mol kg-1 in a mixture of [P4,4,4,8][BScB] and DEGDBE in 1:5 molar ratio. The ion transport properties of the resulting electrolytes are investigated using viscosity, electrical impedance spectroscopy and pulsed-Field Gradient (PFG) NMR. The apparent transfer numbers of ions are calculated from the diffusion coefficients measured by using PFG NMR. PFG NMR data suggested ion association upon addition of Li salt to the [P4,4,4,8][BScB] in DEGDBE solution. This is further confirmed by liquid state 7Li and 11B NMR, and FTIR spectroscopic techniques, which suggest strong interactions between the lithium cation and oxygen atoms of the [BScB]- anion in the hybrid electrolytes. PMID- 29180740 TI - High-efficiency exfoliation of large-area mono-layer graphene oxide with controlled dimension. AB - In this work, we introduce a novel and facile method of exfoliating large-area, single-layer graphene oxide using a shearing stress. The shearing stress reactor consists of two concentric cylinders, where the inner cylinder rotates at controlled speed while the outer cylinder is kept stationary. We found that the formation of Taylor vortex flow with shearing stress can effectively exfoliate the graphite oxide, resulting in large-area single- or few-layer graphene oxide (GO) platelets with high yields (>90%) within 60 min of reaction time. Moreover, the lateral size of exfoliated GO sheets was readily tunable by simply controlling the rotational speed of the reactor and reaction time. Our approach for high-efficiency exfoliation of GO with controlled dimension may find its utility in numerous industrial applications including energy storage, conducting composite, electronic device, and supporting frameworks of catalyst. PMID- 29180741 TI - Observation of Dirac bands in artificial graphene in small-period nanopatterned GaAs quantum wells. AB - Charge carriers in graphene behave like massless Dirac fermions (MDFs) with linear energy-momentum dispersion 1, 2 , providing a condensed-matter platform for studying quasiparticles with relativistic-like features. Artificial graphene (AG)-a structure with an artificial honeycomb lattice-exhibits novel phenomena due to the tunable interplay between topology and quasiparticle interactions 3-6 . So far, the emergence of a Dirac band structure supporting MDFs has been observed in AG using molecular 5 , atomic 6, 7 and photonic systems 8-10 , including those with semiconductor microcavities 11 . Here, we report the realization of an AG that has a band structure with vanishing density of states consistent with the presence of MDFs. This observation is enabled by a very small lattice constant (a = 50 nm) of the nanofabricated AG patterns superimposed on a two-dimensional electron gas hosted by a high-quality GaAs quantum well. Resonant inelastic light-scattering spectra reveal low-lying transitions that are not present in the unpatterned GaAs quantum well. These excitations reveal the energy dependence of the joint density of states for AG band transitions. Fermi level tuning through the Dirac point results in a collapse of the density of states at low transition energy, suggesting the emergence of the MDF linear dispersion in the AG. PMID- 29180742 TI - Out-of-plane heat transfer in van der Waals stacks through electron-hyperbolic phonon coupling. AB - Van der Waals heterostructures have emerged as promising building blocks that offer access to new physics, novel device functionalities and superior electrical and optoelectronic properties 1-7 . Applications such as thermal management, photodetection, light emission, data communication, high-speed electronics and light harvesting 8-16 require a thorough understanding of (nanoscale) heat flow. Here, using time-resolved photocurrent measurements, we identify an efficient out of-plane energy transfer channel, where charge carriers in graphene couple to hyperbolic phonon polaritons 17-19 in the encapsulating layered material. This hyperbolic cooling is particularly efficient, giving picosecond cooling times for hexagonal BN, where the high-momentum hyperbolic phonon polaritons enable efficient near-field energy transfer. We study this heat transfer mechanism using distinct control knobs to vary carrier density and lattice temperature, and find excellent agreement with theory without any adjustable parameters. These insights may lead to the ability to control heat flow in van der Waals heterostructures. PMID- 29180743 TI - A graphene Zener-Klein transistor cooled by a hyperbolic substrate. AB - The engineering of cooling mechanisms is a bottleneck in nanoelectronics. Thermal exchanges in diffusive graphene are mostly driven by defect-assisted acoustic phonon scattering, but the case of high-mobility graphene on hexagonal boron nitride (hBN) is radically different, with a prominent contribution of remote phonons from the substrate. Bilayer graphene on a hBN transistor with a local gate is driven in a regime where almost perfect current saturation is achieved by compensation of the decrease in the carrier density and Zener-Klein tunnelling (ZKT) at high bias. Using noise thermometry, we show that the ZKT triggers a new cooling pathway due to the emission of hyperbolic phonon polaritons in hBN by out of-equilibrium electron-hole pairs beyond the super-Planckian regime. The combination of ZKT transport and hyperbolic phonon polariton cooling renders graphene on BN transistors a valuable nanotechnology for power devices and RF electronics. PMID- 29180745 TI - Molecular variation of tomato yellow leaf curl virus in the insect vector Bemisia tabaci. AB - Insect vectors play significant roles in geminivirus spread and evolution in nature. To date little is known about the population dynamics of begomoviruses in their insect vector Bemisia tabaci. In this study we analyzed the genetic variation of tomato yellow leaf curl virus (TYLCV) in its host plant, Solanum lycopersicum, in its transmission vector B. tabaci raised on TYLCV-infected S. lycopersicum plants, and in B. tabaci after being transferred from S. lycopersicum to Gossypium hirsutum. We found that the levels of variability of TYLCV remained stable in S. lycopersicum plants, but increased significantly in both invasive and indigenous species of B. tabaci. We also presented evidence that the elevated mutation frequencies in TYLCV populations from vector whiteflies were caused mainly by mutations that occurred at several distinct sites within the TYLCV genome. Simultaneous introduction of mutations in the hot spots did not affect the ability of TYLCV to be transmitted by B. tabaci, but reduced its pathogenicity in both S. lycopersicum and Nicotiana benthamiana. Our findings provide new information on population variability of TYLCV in its insect vector, extending the knowledge of the influence of insect vector on plant virus population dynamics. PMID- 29180744 TI - Stem cell senescence drives age-attenuated induction of pituitary tumours in mouse models of paediatric craniopharyngioma. AB - Senescent cells may promote tumour progression through the activation of a senescence-associated secretory phenotype (SASP), whether these cells are capable of initiating tumourigenesis in vivo is not known. Expression of oncogenic beta catenin in Sox2+ young adult pituitary stem cells leads to formation of clusters of stem cells and induction of tumours resembling human adamantinomatous craniopharyngioma (ACP), derived from Sox2- cells in a paracrine manner. Here, we uncover the mechanisms underlying this paracrine tumourigenesis. We show that expression of oncogenic beta-catenin in Hesx1+ embryonic precursors also results in stem cell clusters and paracrine tumours. We reveal that human and mouse clusters are analogous and share a common signature of senescence and SASP. Finally, we show that mice with reduced senescence and SASP responses exhibit decreased tumour-inducing potential. Together, we provide evidence that senescence and a stem cell-associated SASP drive cell transformation and tumour initiation in vivo in an age-dependent fashion. PMID- 29180746 TI - NumtS colonization in mammalian genomes. AB - The colonization of the nuclear genome by mitochondrial DNA is an ongoing process in eukaryotes and plays an important role in genomic variability. Notwithstanding the DNA sequence availability of about 100 complete eukaryotic genomes, up to now NumtS distribution has been fully reported for a small number of sequenced eukaryotic species. With the aim to clarify the time and way of NumtS evolution, we explored the genomic distribution of NumtS in 23 eukaryotic species using an intra/interspecies in silico approach based on a cross-species similarity search and deeply investigate the evolution of NumtS in mammals. The intra- and interspecies analysis underlined how some mitochondrial regions that populated nuclear genomes can be considered as hotspots. Considering the large amount of NumtS we found in platypus and opossum genomes, we hypothesized the occurrence of an earlier colonization that happened prior to the Prototherian/Therian mammal divergence, approximately 160-210 million years ago. These events are still detectable due to the species-specific dynamics that have affected these genomes. Phylogenetic analyses of NumtS derived from two different mitochondrial DNA loci allowed us to recognize the unusual NumtS evolution that acted differently on primate and non-primate species' genomes. PMID- 29180747 TI - Accumbal D2 cells orchestrate innate risk-avoidance according to orexin signals. AB - Excitation of accumbal D2 cells governs vital actions, including avoidance of learned risks, but the origins of this excitation and roles of D2 cells in innate risk-avoidance are unclear. Hypothalamic neurons producing orexins (also called hypocretins) enhance innate risk-avoidance via poorly understood neurocircuits. We describe a direct orexin->D2 excitatory circuit and show that D2 cell activity is necessary for orexin-dependent innate risk-avoidance in mice, thus revealing an unsuspected hypothalamus-accumbens interplay in action selection. PMID- 29180748 TI - Altered responses to social chemosignals in autism spectrum disorder. AB - Autism spectrum disorder (ASD) is characterized by impaired social communication, often attributed to misreading of emotional cues. Why individuals with ASD misread emotions remains unclear. Given that terrestrial mammals rely on their sense of smell to read conspecific emotions, we hypothesized that misreading of emotional cues in ASD partially reflects altered social chemosignaling. We found no difference between typically developed (TD) and cognitively able adults with ASD at explicit detection and perception of social chemosignals. Nevertheless, TD and ASD participants dissociated in their responses to subliminal presentation of these same compounds: the undetected 'smell of fear' (skydiver sweat) increased physiological arousal and reduced explicit and implicit measures of trust in TD but acted opposite in ASD participants. Moreover, two different undetected synthetic putative social chemosignals increased or decreased arousal in TD but acted opposite in ASD participants. These results implicate social chemosignaling as a sensory substrate of social impairment in ASD. PMID- 29180749 TI - Clonal evolution and antigen recognition of anti-nuclear antibodies in acute systemic lupus erythematosus. AB - The evolutional process of disease-associated autoantibodies in systemic lupus erythematosus (SLE) remains to be established. Here we show intraclonal diversification and affinity maturation of anti-nuclear antibody (ANA)-producing B cells in SLE. We identified a panel of monoclonal ANAs recognizing nuclear antigens, such as double-stranded DNA (dsDNA) and ribonucleoproteins (RNPs) from acute SLE subjects. These ANAs had relatively few, but nonetheless critical mutations. High-throughput immunoglobulin sequencing of blood lymphocytes disclosed the existence of sizable ANA lineages shearing critical mutations intraclonally. We further focused on anti-DNA antibodies, which are capable to bind to both single-stranded (ss) and dsDNA at high affinity. Crystal structure and biochemical analysis confirmed a direct role of the mutations in the acquisition of DNA reactivity and also revealed that these anti-DNA antibodies recognized an unpaired region within DNA duplex. Our study unveils the unique properties of high-affinity anti-DNA antibodies that are generated through antigen-driven affinity maturation in acute phase of SLE. PMID- 29180751 TI - Quantum algorithm for preparing the ground state of a system via resonance transition. AB - Preparing the ground state of a system is an important task in physics. We propose a quantum algorithm for preparing the ground state of a physical system that can be simulated on a quantum computer. The system is coupled to an ancillary qubit, by introducing a resonance mechanism between the ancilla qubit and the system, and combined with measurements performed on the ancilla qubit, the system can be evolved to monotonically converge to its ground state through an iterative procedure. We have simulated the application of this algorithm for the Afflect-Kennedy-Lieb-Tasaki model, whose ground state can be used as resource state in one-way quantum computation. PMID- 29180750 TI - Strain-resolved analysis of hospital rooms and infants reveals overlap between the human and room microbiome. AB - Preterm infants exhibit different microbiome colonization patterns relative to full-term infants, and it is speculated that the hospital room environment may contribute to infant microbiome development. Here, we present a genome-resolved metagenomic study of microbial genotypes from the gastrointestinal tracts of infants and from the neonatal intensive care unit (NICU) room environment. Some strains detected in hospitalized infants also occur in sinks and on surfaces, and belong to species such as Staphylococcus epidermidis, Enterococcus faecalis, Pseudomonas aeruginosa, and Klebsiella pneumoniae, which are frequently implicated in nosocomial infection and preterm infant gut colonization. Of the 15 K. pneumoniae strains detected in the study, four were detected in both infant gut and room samples. Time series experiments showed that nearly all strains associated with infant gut colonization can be detected in the room after, and often before, detection in the gut. Thus, we conclude that a component of premature infant gut colonization is the cycle of microbial exchange between the room and the occupant. PMID- 29180752 TI - The E. coli dicarboxylic acid transporters DauA act as a signal transducer by interacting with the DctA uptake system. AB - The Slc26A/SulP family of ions transporter is ubiquitous and widpsread in all kingdon of life. In E. coli, we have demonstrated that the Slc26 protein DauA is a C4-dicarboxilic acids (C4-diC) transporter active at acidic pH. The main C4-diC transporter active at pH7 is DctA and is induced by C4-diC via the DcuS/R two component system. DctA interacts with DcuS, the membrane embedded histidine kinase, to transfers DcuS to the responsive state, i.e. in the absence of DctA, DcuS is permanently "on", but its activity is C4-diC-dependent when in complex with DctA. Using phenotypic characterization, transport assays and protein expression studies, we show that at pH7 full DctA production depends on the presence of DauA. A Bacterial Two Hybrid system indicates that DauA and the sensor complex DctA/DcuS physically interact at the membrane. Pull down experiments completed by co-purification study prove that DauA and DctA interact physically at the membrane. These data open a completely new aspect of the C4-diC metabolism in E. coli and reveals how the bacterial Slc26A uptake systems participate in multiple cellular functions. This constitutes a new example of a bacterial transporter that acts as a processor in a transduction pathway. PMID- 29180753 TI - Dissipative quantum error correction and application to quantum sensing with trapped ions. AB - Quantum-enhanced measurements hold the promise to improve high-precision sensing ranging from the definition of time standards to the determination of fundamental constants of nature. However, quantum sensors lose their sensitivity in the presence of noise. To protect them, the use of quantum error-correcting codes has been proposed. Trapped ions are an excellent technological platform for both quantum sensing and quantum error correction. Here we present a quantum error correction scheme that harnesses dissipation to stabilize a trapped-ion qubit. In our approach, always-on couplings to an engineered environment protect the qubit against spin-flips or phase-flips. Our dissipative error correction scheme operates in a continuous manner without the need to perform measurements or feedback operations. We show that the resulting enhanced coherence time translates into a significantly enhanced precision for quantum measurements. Our work constitutes a stepping stone towards the paradigm of self-correcting quantum information processing.

AB - Statements on conflicts of interest provide important information for readers of scientific papers. There is now compelling evidence from several fields that papers reporting funding from organizations that have an interest in the results often generate different findings from those that do not report such funding. We describe the findings of an analysis of correspondence between representatives of a major soft drinks company and scientists researching childhood obesity. Although the studies report no influence by the funder, the correspondence describes detailed exchanges on the study design, presentation of results and acknowledgement of funding. This raises important questions about the meaning of standard statements on conflicts of interest. PMID- 29180755 TI - Nav channel binder containing a specific conjugation-site based on a low toxicity beta-scorpion toxin. AB - Voltage-gated sodium (Nav) channels play a key role in generating action potentials which leads to physiological signaling in excitable cells. The availability of probes for functional studies of mammalian Nav is limited. Here, by introducing two amino acid substitutions into the beta scorpion toxin Ts1, we have chemically synthesized a novel binder [S14R, W50Pra]Ts1 for Nav with high affinity, low dissociation rate and reduced toxicity while retaining the capability of conjugating Ts1 with molecules of interests for different applications. Using the fluorescent-dye conjugate, [S14R, W50Pra(Bodipy)]Ts1, we confirmed its binding to Nav1.4 through Lanthanide-based Resonance Energy Transfer. Moreover, using the gold nanoparticle conjugate, [S14R, W50Pra(AuNP)]Ts1, we were able to optically stimulate dorsal root ganglia neurons and generate action potentials with visible light via the optocapacitive effect as previously reported. [S14R, W50Pra]Ts1 is a novel probe with great potential for wider applications in Nav-related neuroscience research. PMID- 29180756 TI - Asymmetrical bipolar nanosecond electric pulse widths modify bipolar cancellation. AB - A bipolar (BP) nanosecond electric pulse (nsEP) exposure generates reduced calcium influx compared to a unipolar (UP) nsEP. This attenuated physiological response from a BP nsEP exposure is termed "bipolar cancellation" (BPC). The predominant BP nsEP parameters that induce BPC consist of a positive polarity (?) front pulse followed by the delivery of a negative polarity (?) back pulse of equal voltage and width; thereby the duration is twice a UP nsEP exposure. We tested these BPC parameters, and discovered that a BP nsEP with symmetrical pulse widths is not required to generate BPC. For example, our data revealed the physiological response initiated by a ?900 nsEP exposure can be cancelled by a second pulse that is a third of its duration. However, we observed a complete loss of BPC from a ?300 nsEP followed by a ?900 nsEP exposure. Spatiotemporal analysis revealed these asymmetrical BP nsEP exposures generate distinct local YO PRO(r)-1 uptake patterns across the plasma membrane. From these findings, we generated a conceptual model that suggests BPC is a phenomenon balanced by localized charging and discharging events across the membrane. PMID- 29180757 TI - Discovery of High-Affinity PDGF-VEGFR Interactions: Redefining RTK Dynamics. AB - Nearly all studies of angiogenesis have focused on uni-family ligand-receptor binding, e.g., VEGFs bind to VEGF receptors, PDGFs bind to PDGF receptors, etc. The discovery of VEGF-PDGFRs binding challenges this paradigm and calls for investigation of other ligand-receptor binding possibilities. We utilized surface plasmon resonance to identify and measure PDGF-to-VEGFR binding rates, establishing cut-offs for binding and non-binding interactions. We quantified the kinetics of the recent VEGF-A:PDGFRbeta interaction for the first time with KD = 340 pM. We discovered new PDGF:VEGFR2 interactions with PDGF-AA:R2 KD = 530 nM, PDGF-AB:R2 KD = 110 pM, PDGF-BB:R2 KD = 40 nM, and PDGF-CC:R2 KD = 70 pM. We computationally predict that cross-family PDGF binding could contribute up to 96% of VEGFR2 ligation in healthy conditions and in cancer. Together the identification, quantification, and simulation of these novel cross-family interactions posits new mechanisms for understanding anti-angiogenic drug resistance and presents an expanded role of growth factor signaling with significance in health and disease. PMID- 29180758 TI - Knowledge graph prediction of unknown adverse drug reactions and validation in electronic health records. AB - Unknown adverse reactions to drugs available on the market present a significant health risk and limit accurate judgement of the cost/benefit trade-off for medications. Machine learning has the potential to predict unknown adverse reactions from current knowledge. We constructed a knowledge graph containing four types of node: drugs, protein targets, indications and adverse reactions. Using this graph, we developed a machine learning algorithm based on a simple enrichment test and first demonstrated this method performs extremely well at classifying known causes of adverse reactions (AUC 0.92). A cross validation scheme in which 10% of drug-adverse reaction edges were systematically deleted per fold showed that the method correctly predicts 68% of the deleted edges on average. Next, a subset of adverse reactions that could be reliably detected in anonymised electronic health records from South London and Maudsley NHS Foundation Trust were used to validate predictions from the model that are not currently known in public databases. High-confidence predictions were validated in electronic records significantly more frequently than random models, and outperformed standard methods (logistic regression, decision trees and support vector machines). This approach has the potential to improve patient safety by predicting adverse reactions that were not observed during randomised trials. PMID- 29180760 TI - Detectability of Breast Tumor by a Hand-held Impulse-Radar Detector: Performance Evaluation and Pilot Clinical Study. AB - In this report, a hand-held impulse-radar breast cancer detector is presented and the detectability of malignant breast tumors is demonstrated in the clinical test at Hiroshima University Hospital, Hiroshima, Japan. The core functional parts of the detector consist of 65-nm technology complementary metal-oxide-semiconductor (CMOS) integrated circuits covering the ultrawideband width from 3.1 to 10.6 GHz, which enable the generation and transmission of Gaussian monocycle pulse (GMP) with the pulse width of 160 ps and single port eight throw (SP8T) switching matrices for controlling the combination of 4 * 4 cross-shaped dome antenna array. The detector is designed to be placed on the breast with the patient in the supine position. The detectability of malignant tumors is confirmed in excised breast tissues after total mastectomy surgery. The three-dimensional positions of the tumors in the imaging results are consistent with the results of histopathology analysis. The clinical tests are conducted by a clinical doctor for five patients at the hospital. The malignant tumors include invasive ductal carcinoma (IDC) and ductal carcinoma in situ (DCIS). The final confocal imaging results are consistent with those of Magnetic Resonance Imaging (MRI), demonstrating the feasibility of the hand-held impulse-radar detector for malignant breast tumors. PMID- 29180759 TI - Nano-enabled pancreas cancer immunotherapy using immunogenic cell death and reversing immunosuppression. AB - While chemotherapy delivery by nanocarriers has modestly improved the survival prospects of pancreatic ductal adenocarcinoma (PDAC), additional engagement of the immune response could be game changing. We demonstrate a nano-enabled approach for accomplishing robust anti-PDAC immunity in syngeneic mice through the induction of immunogenic cell death (ICD) as well as interfering in the immunosuppressive indoleamine 2,3-dioxygenase (IDO) pathway. This is accomplished by conjugating the IDO inhibitor, indoximod (IND), to a phospholipid that allows prodrug self-assembly into nanovesicles or incorporation into a lipid bilayer that encapsulates mesoporous silica nanoparticles (MSNP). The porous MSNP interior allows contemporaneous delivery of the ICD-inducing chemotherapeutic agent, oxaliplatin (OX). The nanovesicles plus free OX or OX/IND-MSNP induce effective innate and adaptive anti-PDAC immunity when used in a vaccination approach, direct tumor injection or intravenous biodistribution to an orthotopic PDAC site. Significant tumor reduction or eradication is accomplishable by recruiting cytotoxic T lymphocytes, concomitant with downregulation of Foxp3+ T cells. PMID- 29180761 TI - Combined inhibition of MEK and nuclear ERK translocation has synergistic antitumor activity in melanoma cells. AB - Genetic alterations in BRAF, NRAS and NF1 that activate the ERK cascade, account for over 80% of metastatic melanomas. However, ERK cascade inhibitors have been proven beneficial almost exclusively for BRAF mutant melanomas. One of the hallmarks of the ERK cascade is the nuclear translocation of ERK1/2, which is important mainly for the induction of proliferation. This translocation can be inhibited by the NTS-derived peptide (EPE) that blocks the ERK1/2-importin7 interaction, inhibits the nuclear translocation of ERK1/2, and arrests active ERK1/2 in the cytoplasm. In this study, we found that the EPE peptide significantly reduced the viability of not only BRAF, but also several NRAS and NF1 mutant melanomas. Importantly, combination of the EPE peptide and trametinib showed synergy in reducing the viability of some NRAS mutant melanomas, an effect driven by the partial preservation of negative feedback loops. The same combination significantly reduced the viability of other melanoma cells, including those resistant to mono-treatment with EPE peptide and ERK cascade inhibitors. Our study indicates that targeting the nuclear translocation of ERK1/2, in combination with MEK inhibitors can be used for the treatment of different mutant melanomas. PMID- 29180762 TI - Linear magnetoelectric effect in gothite, alpha-FeOOH. AB - By means of symmetry analysis, density functional theory calculations, and Monte Carlo simulations we show that goethite, alpha-FeOOH, is a linear magnetoelectric below its Neel temperature T N = 400 K. The experimentally observed magnetic field induced spin-flop phase transition results in either change of direction of electric polarization or its suppression. Estimated value of magnetoelectric coefficient is 0.57 MUC . m-2 . T-1. The abundance of goethite in nature makes it arguably the most widespread magnetoelectric material. PMID- 29180763 TI - Identification of genes expressed in a mesenchymal subset regulating prostate organogenesis using tissue and single cell transcriptomics. AB - Prostate organogenesis involves epithelial growth controlled by inductive signalling from specialised mesenchymal subsets. To identify pathways active in mesenchyme we used tissue and single cell transcriptomics to define mesenchymal subsets and subset-specific transcript expression. We documented transcript expression using Tag-seq and RNA-seq in female rat Ventral Mesenchymal Pad (VMP) as well as adjacent urethra comprised of smooth muscle and peri-urethral mesenchyme. Transcripts enriched in female VMP were identified with Tag-seq of microdissected tissue, RNA-seq of cell populations, and single cells. We identified 400 transcripts as enriched in the VMP using bio-informatic comparisons of Tag-seq and RNA-seq data, and 44 were confirmed by single cell RNA seq. Cell subset analysis showed that VMP and adjacent mesenchyme were composed of distinct cell types and that each tissue contained two subgroups. Markers for these subgroups were highly subset specific. Thirteen transcripts were validated by qPCR to confirm cell specific expression in microdissected tissues, as well as expression in neonatal prostate. Immunohistochemical staining demonstrated that Ebf3 and Meis2 showed a restricted expression pattern in female VMP and prostate mesenchyme. We conclude that prostate inductive mesenchyme shows limited cellular heterogeneity and that transcriptomic analysis identified new mesenchymal subset transcripts associated with prostate organogenesis. PMID- 29180764 TI - Synthesis and implication of novel poly(acrylic acid)/nanosorbent embedded hydrogel composite for lead ion removal. AB - Lead stands second among the deadly heavy metal pollutants owing to the incompetent mechanism possessed by the human body for its removal. A polymeric hydrogel in the form of composite was prepared using acrylic acid (monomer) and novel nanofiller that possess super adsorbent properties with restricted gel seepage into flowing ionic liquid. The filler used is an adsorbent which is biocompatible, biodegradable, economical, abundant, non-hazardous and easy to synthesize. The invariably porous nanofiller, the Nanobentonite(clay), was synthesized using ion exchange reaction by creating acidic environment for accelerated dispersion with exfoliation by CTAB to enhance cation exchange capacity. NanobentoFnite was capable of removing >97% lead ion in batch adsorption study and followed pseudo-second order kinetic model. Freundlich isotherm suggested a removal capacity of ~20 mg/g. Thus, the successfully experimented adsorbent was implicated as filler to form polyacrylic acid nanoclay hydrogel polymerized in ultrasonic bath. The amount of filler was varied from 0.25 to 2 wt% to get 94% removal, analyzed using ICP-OES. The prepared adsorbents were characterized before and after adsorption using TEM, FESEM, XRD, FTIR and DSC to understand the structural changes and metal-sorbent interaction. Thus, the novel nanosorbent/composite are promiscuous and competent in terms of availability, reusability and longevity to remove heavy metal ions. PMID- 29180765 TI - The inhibitory effect of minocycline on radiation-induced neuronal apoptosis via AMPKalpha1 signaling-mediated autophagy. AB - Due to an increasing concern about radiation-induced cognitive deficits for brain tumor patients receiving radiation therapy, developing and evaluating countermeasures has become inevitable. Our previous study has found that minocycline, a clinical available antibiotics that can easily cross the blood brain barrier, mitigates radiation-induced long-term memory loss in rats, accompanied by decreased hippocampal neuron apoptosis. Thus, in the present study, we report an unknown mechanism underlying the neuroprotective effect of minocycline. We demonstrated that minocycline prevented primary neurons from radiation-induced apoptosis and promoted radiation-induced autophagy in vitro. Moreover, using an immortalized mouse hippocampal neuronal cell line, HT22 cells, we found that the protective effect of minocycline on irradiated HT22 cells was not related to DNA damage repair since minocycline did not facilitate DNA DSB repair in irradiated HT22 cells. Further investigation showed that minocycline significantly enhanced X-irradiation-induced AMPKalpha1 activation and autophagy, thus resulting in decreased apoptosis. Additionally, although the antioxidant potential of minocycline might contribute to its apoptosis-inhibitory effect, it was not involved in its enhancive effect on radiation-induced AMPKalpha1-mediated autophagy. Taken together, we have revealed a novel mechanism for the protective effect of minocycline on irradiated neurons, e.g. minocycline protects neurons from radiation-induced apoptosis via enhancing radiation-induced AMPKalpha1 mediated autophagy.

PMID- 29180767 TI - Frequency and reactivity of antigen-specific T cells were concurrently measured through the combination of artificial antigen-presenting cell, MACS and ELISPOT. AB - Conventional peptide-major histocompatibility complex (pMHC) multimer staining, intracellular cytokine staining, and enzyme-linked immunospot (ELISPOT) assay cannot concurrently determine the frequency and reactivity of antigen-specific T cells (AST) in a single assay. In this report, pMHC multimer, magnetic-activated cell sorting (MACS), and ELISPOT techniques have been integrated into a micro well by coupling pMHC multimers onto cell-sized magnetic beads to characterize AST cell populations in a 96-well microplate which pre-coated with cytokine capture antibodies. This method, termed AAPC-microplate, allows the enumeration and local cytokine production of AST cells in a single assay without using flow cytometry or fluorescence intensity scanning, thus will be widely applicable. Here, ovalbumin257-264-specific CD8+ T cells from OT-1 T cell receptor (TCR) transgenic mice were measured. The methodological accuracy, specificity, reproducibility, and sensitivity in enumerating AST cells compared well with conventional pMHC multimer staining. Furthermore, the AAPC-microplate was applied to detect the frequency and reactivity of Hepatitis B virus (HBV) core antigen18 27- and surface antigen183-191-specific CD8+ T cells for the patients, and was compared with conventional method. This method without the need of high-end instruments may facilitate the routine analysis of patient-specific cellular immune response pattern to a given antigen in translational studies.

AB - Sleep is a dynamic process comprising multiple stages, each associated with distinct electrophysiological properties and potentially serving different functions. While these phenomena are well described in vertebrates, it is unclear if invertebrates have distinct sleep stages. We perform local field potential (LFP) recordings on flies spontaneously sleeping, and compare their brain activity to flies induced to sleep using either genetic activation of sleep promoting circuitry or the GABAA agonist Gaboxadol. We find a transitional sleep stage associated with a 7-10 Hz oscillation in the central brain during spontaneous sleep. Oscillatory activity is also evident when we acutely activate sleep-promoting neurons in the dorsal fan-shaped body (dFB) of Drosophila. In contrast, sleep following Gaboxadol exposure is characterized by low-amplitude LFPs, during which dFB-induced effects are suppressed. Sleep in flies thus appears to involve at least two distinct stages: increased oscillatory activity, particularly during sleep induction, followed by desynchronized or decreased brain activity. PMID- 29180769 TI - Performance on emotional tasks engaging cognitive control depends on emotional intelligence abilities: an ERP study. AB - Cognitive control is a key process in decision making and adequately adapting our behavior to the environment. Previous studies have provided evidence of a lower capacity for cognitive control in emotion-laden contexts in comparison with neutral contexts. The aim of the present research was to study changes in cognitive control performance as a function of emotional intelligence (EI) level in contexts involving emotional information. The study sample was composed of 2 groups of 22 participants each: the high and low EI group. Participants carried out an emotional go/no-go task while brain activity was recorded by EEG. N2 and P3 ERPs were used as indices of cognitive control processing. Participants with higher EI showed a larger N2, reflecting a greater capacity for cognitive control related to changes in conflict monitoring, and to a better detection and evaluation of the emotional stimuli. Moreover, in general, response inhibition accuracy was reduced when emotional information was involved in this process. Our findings reveal that neural mechanisms underlying tasks that engage cognitive control depend on emotional content and EI level. This study indicates the important role played by EI in the relationship between emotion and cognition. EI training may be a very useful tool for improving performance in emotion-laden contexts. PMID- 29180770 TI - Optical gain in colloidal quantum dots achieved with direct-current electrical pumping. AB - Chemically synthesized semiconductor quantum dots (QDs) can potentially enable solution-processable laser diodes with a wide range of operational wavelengths, yet demonstrations of lasing from the QDs are still at the laboratory stage. An important challenge-realization of lasing with electrical injection-remains unresolved, largely due to fast nonradiative Auger recombination of multicarrier states that represent gain-active species in the QDs. Here we present population inversion and optical gain in colloidal nanocrystals realized with direct-current electrical pumping. Using continuously graded QDs, we achieve a considerable suppression of Auger decay such that it can be outpaced by electrical injection. Further, we apply a special current-focusing device architecture, which allows us to produce high current densities (j) up to ~18 A cm-2 without damaging either the QDs or the injection layers. The quantitative analysis of electroluminescence and current-modulated transmission spectra indicates that with j = 3-4 A cm-2 we achieve the population inversion of the band-edge states. PMID- 29180771 TI - Programmed coherent coupling in a synthetic DNA-based excitonic circuit. AB - Natural light-harvesting systems spatially organize densely packed chromophore aggregates using rigid protein scaffolds to achieve highly efficient, directed energy transfer. Here, we report a synthetic strategy using rigid DNA scaffolds to similarly program the spatial organization of densely packed, discrete clusters of cyanine dye aggregates with tunable absorption spectra and strongly coupled exciton dynamics present in natural light-harvesting systems. We first characterize the range of dye-aggregate sizes that can be templated spatially by A-tracts of B-form DNA while retaining coherent energy transfer. We then use structure-based modelling and quantum dynamics to guide the rational design of higher-order synthetic circuits consisting of multiple discrete dye aggregates within a DX-tile. These programmed circuits exhibit excitonic transport properties with prominent circular dichroism, superradiance, and fast delocalized exciton transfer, consistent with our quantum dynamics predictions. This bottom up strategy offers a versatile approach to the rational design of strongly coupled excitonic circuits using spatially organized dye aggregates for use in coherent nanoscale energy transport, artificial light-harvesting, and nanophotonics. PMID- 29180772 TI - Dislocation nucleation facilitated by atomic segregation. AB - Surface segregation-the enrichment of one element at the surface, relative to the bulk-is ubiquitous to multi-component materials. Using the example of a Cu-Au solid solution, we demonstrate that compositional variations induced by surface segregation are accompanied by misfit strain and the formation of dislocations in the subsurface region via a surface diffusion and trapping process. The resulting chemically ordered surface regions acts as an effective barrier that inhibits subsequent dislocation annihilation at free surfaces. Using dynamic, atomic-scale resolution electron microscopy observations and theory modelling, we show that the dislocations are highly active, and we delineate the specific atomic-scale mechanisms associated with their nucleation, glide, climb, and annihilation at elevated temperatures. These observations provide mechanistic detail of how dislocations nucleate and migrate at heterointerfaces in dissimilar-material systems. PMID- 29180773 TI - Chiral liquid crystal colloids. AB - Colloidal particles disturb the alignment of rod-like molecules of liquid crystals, giving rise to long-range interactions that minimize the free energy of distorted regions. Particle shape and topology are known to guide this self assembly process. However, how chirality of colloidal inclusions affects these long-range interactions is unclear. Here we study the effects of distortions caused by chiral springs and helices on the colloidal self-organization in a nematic liquid crystal using laser tweezers, particle tracking and optical imaging. We show that chirality of colloidal particles interacts with the nematic elasticity to predefine chiral or racemic colloidal superstructures in nematic colloids. These findings are consistent with numerical modelling based on the minimization of Landau-de Gennes free energy. Our study uncovers the role of chirality in defining the mesoscopic order of liquid crystal colloids, suggesting that this feature may be a potential tool to modulate the global orientated self organization of these systems. PMID- 29180774 TI - Spontaneous exchange bias formation driven by a structural phase transition in the antiferromagnetic material. AB - Most of the magnetic devices in advanced electronics rely on the exchange bias effect, a magnetic interaction that couples a ferromagnetic and an antiferromagnetic material, resulting in a unidirectional displacement of the ferromagnetic hysteresis loop by an amount called the 'exchange bias field'. Setting and optimizing exchange bias involves cooling through the Neel temperature of the antiferromagnetic material in the presence of a magnetic field. Here we demonstrate an alternative process for the generation of exchange bias. In IrMn/FeCo bilayers, a structural phase transition in the IrMn layer develops at room temperature, exchange biasing the FeCo layer as it propagates. Once the process is completed, the IrMn layer contains very large single-crystal grains, with a large density of structural defects within each grain, which are promoted by the FeCo layer. The magnetic characterization indicates that these structural defects in the antiferromagnetic layer are behind the resulting large value of the exchange bias field and its good thermal stability. This mechanism for establishing the exchange bias in such a system can contribute towards the clarification of fundamental aspects of this exchange interaction. PMID- 29180775 TI - Ubiquitous formation of bulk Dirac cones and topological surface states from a single orbital manifold in transition-metal dichalcogenides. AB - Transition-metal dichalcogenides (TMDs) are renowned for their rich and varied bulk properties, while their single-layer variants have become one of the most prominent examples of two-dimensional materials beyond graphene. Their disparate ground states largely depend on transition metal d-electron-derived electronic states, on which the vast majority of attention has been concentrated to date. Here, we focus on the chalcogen-derived states. From density-functional theory calculations together with spin- and angle-resolved photoemission, we find that these generically host a co-existence of type-I and type-II three-dimensional bulk Dirac fermions as well as ladders of topological surface states and surface resonances. We demonstrate how these naturally arise within a single p-orbital manifold as a general consequence of a trigonal crystal field, and as such can be expected across a large number of compounds. Already, we demonstrate their existence in six separate TMDs, opening routes to tune, and ultimately exploit, their topological physics.

PMID- 29180776 TI - Temporary formation of highly conducting domain walls for non-destructive read out of ferroelectric domain-wall resistance switching memories. AB - Erasable conductive domain walls in insulating ferroelectric thin films can be used for non-destructive electrical read-out of the polarization states in ferroelectric memories. Still, the domain-wall currents extracted by these devices have not yet reached the intensity and stability required to drive read out circuits operating at high speeds. This study demonstrated non-destructive read-out of digital data stored using specific domain-wall configurations in epitaxial BiFeO3 thin films formed in mesa-geometry structures. Partially switched domains, which enable the formation of conductive walls during the read operation, spontaneously retract when the read voltage is removed, reducing the accumulation of mobile defects at the domain walls and potentially improving the device stability. Three-terminal memory devices produced 14 nA read currents at an operating voltage of 5 V, and operated up to T = 85 degrees C. The gap length can also be smaller than the film thickness, allowing the realization of ferroelectric memories with device dimensions far below 100 nm. PMID- 29180778 TI - The development of bioresorbable composite polymeric implants with high mechanical strength. AB - Implants for the treatment of tissue defects should mimic the mechanical properties of the native tissue of interest and should be resorbable as well as biocompatible. In this work, we developed a scaffold from variants of poly(glycolic) acid which were braided and coated with an elastomer of poly(glycolide-co-caprolactone) and crosslinked. The coating of the scaffold with the elastomer led to higher mechanical strength in terms of compression, expansion and elasticity compared to braids without the elastomer coating. These composite scaffolds were found to have expansion properties similar to metallic stents, utilizing materials which are typically much weaker than metal. We optimized the mechanical properties of the implant by tuning the elastomer branching structure, crosslink density, and molecular weight. The scaffolds were shown to be highly resorbable following implantation in a porcine femoral artery. Biocompatibility was studied in vivo in an ovine model by implanting the scaffolds into femoral arteries. The scaffolds were able to support an expanded open lumen over 12 months in vivo and also fully resorbed by 18 months in the ovine model. PMID- 29180779 TI - Plating and stripping calcium in an organic electrolyte. AB - There is considerable interest in multivalent cation batteries, such as those based on magnesium, calcium or aluminium. Most attention has focused on magnesium. In all cases the metal anode represents a significant challenge. Recent work has shown that calcium can be plated and stripped, but only at elevated temperatures, 75 to 100 degrees C, with small capacities, typically 0.165 mAh cm-2, and accompanied by significant side reactions. Here we demonstrate that calcium can be plated and stripped at room temperature with capacities of 1 mAh cm-2 at a rate of 1 mA cm-2, with low polarization (~100 mV) and in excess of 50 cycles. The dominant product is calcium, accompanied by a small amount of CaH2 that forms by reaction between the deposited calcium and the electrolyte, Ca(BH4)2 in tetrahydrofuran (THF). This occurs in preference to the reactions which take place in most electrolyte solutions forming CaCO3, Ca(OH)2 and calcium alkoxides, and normally terminate the electrochemistry. The CaH2 protects the calcium metal at open circuit. Although this work does not solve all the problems of calcium as an anode in calcium-ion batteries, it does demonstrate that significant quantities of calcium can be plated and stripped at room temperature with low polarization. PMID- 29180780 TI - In situ investigation of phase transformations in Ti-6Al-4V under additive manufacturing conditions combining laser melting and high-speed micro-X-ray diffraction. AB - We present combined in situ X-ray diffraction and high-speed imaging to monitor the phase evolution upon cyclic rapid laser heating and cooling mimicking the direct energy deposition of Ti-6Al-4V in real time. Additive manufacturing of the industrially relevant alloy Ti-6Al-4V is known to create a multitude of phases and microstructures depending on processing technology and parameters. Current setups are limited by an averaged measurement through the solid and liquid parts. In this work the combination of a micro-focused intense X-ray beam, a fast detector and unidirectional cooling provide the spatial and temporal resolution to separate contributions from solid and liquid phases in limited volumes. Upon rapid heating and cooling, the beta <-> alpha' phase transformation is observed repeatedly. At room temperature, single phase alpha' is observed. Secondary beta formation upon formation of alpha' is attributed to V partitioning to the beta phase leading to temporary stabilization. Lattice strains in the alpha'-phase are found to be sensitive to the alpha' -> beta phase transformation. Based on lattice strain of the beta-phase, the martensite start temperature is estimated at 923 K in these experiments. Off-axis high speed imaging confirms a technically relevant solidification front velocity and cooling rate of 10.3 mm/s and 4500 K/s, respectively. PMID- 29180781 TI - The Relationship between Secondary Forest and Environmental Factors in the Southern Taihang Mountains. AB - It is important to understand the effects of environmental factors on secondary forest assembly for effective afforestation and vegetation restoration. We studied 24 20 m * 20 m quadrats of natural secondary forest in the southern Taihang Mountains. Canonical correspondence analysis (CCA) and two-way indicator hydrocarbon analysis were used to analyse the relationship between community vegetation and environmental factors. The CCA showed that 13 terrain and soil variables shared 68.17% of the total variance. The principal environmental variables, based on the most parsimonious CCA model, were (in order) elevation, soil total N, soil gravel content, slope, soil electrical conductivity, and pH. Samples were clustered into four forest types, with forest diversity affected by elevation, nutrients, and water gradients. Topographical variables affected forest assembly more than soil variables. Species diversity was evaluated using the Shannon-Wiener, Simpson's diversity, and Pielou's evenness indexes. The environmental factors that affected species distribution had different effects on species diversity. The vegetation-environment relationship in the southern region was different than the central region of the Taihang Mountains, and vegetation restoration was at an early stage. The terrain of the southern region, especially elevation and slope, should be considered for vegetation restoration and conservation. PMID- 29180782 TI - Alpha-helicoidal HEAT-like Repeat Proteins (alphaRep) Selected as Interactors of HIV-1 Nucleocapsid Negatively Interfere with Viral Genome Packaging and Virus Maturation. AB - A new generation of artificial proteins, derived from alpha-helicoidal HEAT-like repeat protein scaffolds (alphaRep), was previously characterized as an effective source of intracellular interfering proteins. In this work, a phage-displayed library of alphaRep was screened on a region of HIV-1 Gag polyprotein encompassing the C-terminal domain of the capsid, the SP1 linker and the nucleocapsid. This region is known to be essential for the late steps of HIV-1 life cycle, Gag oligomerization, viral genome packaging and the last cleavage step of Gag, leading to mature, infectious virions. Two strong alphaRep binders were isolated from the screen, alphaRep4E3 (32 kDa; 7 internal repeats) and alphaRep9A8 (28 kDa; 6 internal repeats). Their antiviral activity against HIV-1 was evaluated in VLP-producer cells and in human SupT1 cells challenged with HIV 1. Both alphaRep4E3 and alphaRep9A8 showed a modest but significant antiviral effects in all bioassays and cell systems tested. They did not prevent the proviral integration reaction, but negatively interfered with late steps of the HIV-1 life cycle: alphaRep4E3 blocked the viral genome packaging, whereas alphaRep9A8 altered both virus maturation and genome packaging. Interestingly, SupT1 cells stably expressing alphaRep9A8 acquired long-term resistance to HIV-1, implying that alphaRep proteins can act as antiviral restriction-like factors. PMID- 29180784 TI - Singlet oxygen-mediated selective C-H bond hydroperoxidation of ethereal hydrocarbons. AB - Singlet O2 is a key reactive oxygen species responsible for photodynamic therapy and is generally recognized to be chemically reactive towards C=C double bonds. Herein, we report the hydroperoxidation/lactonization of alpha-ethereal C-H bonds by singlet O2 (1Deltag) under exceptionally mild conditions, i.e., room temperature and ambient pressure, with modest to high yields (38~90%) and excellent site selectivity. Singlet O2 has been known for > 90 years, but was never reported to be able to react with weakly activated C-H bonds in saturated hydrocarbons. Theoretical calculations indicate that singlet O2 directly inserts into the alpha-ethereal C-H bond in one step with conservation of steric configuration in products. The current discovery of chemical reaction of singlet oxygen with weakly activated solvent C-H bonds, in addition to physical relaxation pathway, provides an important clue to a 35-year-old unresolved mystery regarding huge variations of solvent dependent lifetime of singlet O2. PMID- 29180783 TI - Ingestion of artificial sweeteners leads to caloric frustration memory in Drosophila. AB - Non-caloric artificial sweeteners (NAS) are widely used in modern human food, raising the question about their health impact. Here we have asked whether NAS consumption is a neutral experience at neural and behavioral level, or if NAS can be interpreted and remembered as negative experience. We used behavioral and imaging approaches to demonstrate that Drosophila melanogaster learn the non caloric property of NAS through post-ingestion process. These results show that sweet taste is predictive of an energy value, and its absence leads to the formation of what we call Caloric Frustration Memory (CFM) that devalues the NAS or its caloric enantiomer. CFM formation involves activity of the associative memory brain structure, the mushroom bodies (MBs). In vivo calcium imaging of MB input dopaminergic neurons that respond to sugar showed a reduced response to NAS after CFM formation. Altogether, these findings demonstrate that NAS are a negative experience for the brain. PMID- 29180785 TI - Deleting the mouse Hsd17b1 gene results in a hypomorphic Naglu allele and a phenotype mimicking a lysosomal storage disease. AB - HSD17B1 is a steroid metabolising enzyme. We have previously generated knockout mice that had the entire coding region of Hsd17b1 replaced with lacZ-neo cassette (Hsd17b1-LacZ/Neo mice). This resulted in a 90% reduction of HSD17B1 activity, associated with severe subfertility in the knockout females. The present study indicates that Hsd17b1-LacZ/Neo male mice have a metabolic phenotype, including reduced adipose mass, increased lean mass and lipid accumulation in the liver. During the characterisation of this metabolic phenotype, it became evident that the expression of the Naglu gene, located closely upstream of Hsd17b1, was severely reduced in all tissues analysed. Similar results were obtained from Hsd17b1-LacZ mice after removing the neo cassette from the locus or by crossing the Hsd17b1-LacZ/Neo mice with transgenic mice constitutively expressing human HSD17B1. The deficiency of Naglu caused the accumulation of glycosaminoglycans in all studied mouse models lacking the Hsd17b1 gene. The metabolic phenotypes of the Hsd17b1 knockout mouse models were recapitulated in Naglu knockout mice. Based on the data we propose that the Hsd17b1 gene includes a regulatory element controlling Naglu expression and the metabolic phenotype in mice lacking the Hsd17b1 genomic region is caused by the reduced expression of Naglu rather than the lack of Hsd17b1. PMID- 29180786 TI - New design model for high efficiency cylindrical diffractive microlenses. AB - A new model, i.e., the decreasing thickness model (DTM) is proposed and employed for designing the cylindrical diffractive microlenses (CDMs). Focal performances of the designed CDMs are theoretically investigated by solving Maxwell's equations with the boundary element method. For comparison, the CDMs designed by the traditional equal thickness model (ETM) are also studied. Theoretical simulations demonstrate that focal performances of the designed CDMs are improved a lot via replacing the traditional ETM with the proposed DTM. Concretely, the focal efficiency is heightened and the focal spot size is shrunk. Experimental measurements verify the theoretical simulations well. Especially, the above mentioned improvements become more prominent for the CDM with a higher numerical aperture. PMID- 29180787 TI - Towards the cell-instructive bactericidal substrate: exploring the combination of nanotopographical features and integrin selective synthetic ligands. AB - Engineering the interface between biomaterials and tissues is important to increase implant lifetime and avoid failures and revision surgeries. Permanent devices should enhance attachment and differentiation of stem cells, responsible for injured tissue repair, and simultaneously discourage bacterial colonization; this represents a major challenge. To take first steps towards such a multifunctional surface we propose merging topographical and biochemical cues on the surface of a clinically relevant material such as titanium. In detail, our strategy combines antibacterial nanotopographical features with integrin selective synthetic ligands that can rescue the adhesive capacity of the surfaces and instruct mesenchymal stem cell (MSC) response. To this end, a smooth substrate and two different high aspect ratio topographies have been produced and coated either with an alphavbeta3-selective peptidomimetic, an alpha5beta1 selective peptidomimetic, or an RGD/PHSRN peptidic molecule. Results showed that antibacterial effects of the substrates could be maintained when tested on pathogenic Pseudomonas aeruginosa. Further, functionalization increased MSC adhesion to the surfaces and the alphavbeta3-selective peptidomimetic-coated nanotopographies promoted osteogenesis. Such a dual physicochemical approach to achieve multifunctional surfaces represents a first step in the design of novel cell-instructive biomaterial surfaces. PMID- 29180788 TI - Pseudotrichonympha leei, Pseudotrichonympha lifesoni, and Pseudotrichonympha pearti, new species of parabasalian flagellates and the description of a rotating subcellular structure. AB - Pseudotrichonympha is a large and structurally complex genus of parabasalian protists that play a key role in the digestion of lignocellulose in the termite hindgut. Like many termite symbionts, it has a conspicuous body plan that makes genus-level identification relatively easy, but species-level diversity of Pseudotrichonympha is understudied. Molecular surveys have suggested the diversity is much greater than the current number of described species, and that many "species" described in multiple hosts are in fact different, but gene sequences from formally described species remain a rarity. Here we describe three new species from Coptotermes and Prorhinotermes hosts, including small subunit ribosomal RNA (SSU rRNA) sequences from single cells. Based on host identification by morphology and DNA barcoding, as well as the morphology and phylogenetic position of each symbiont, all three represent new Pseudotrichonympha species: P. leei, P. lifesoni, and P. pearti. Pseudotrichonympha leei and P. lifesoni, both from Coptotermes, are closely related to other Coptotermes symbionts including the type species, P. hertwigi. Pseudotrichonympha pearti is the outlier of the trio, more distantly related to P. leei and P. lifesoni than they are to one another, and contains unique features, including an unusual rotating intracellular structure of unknown function. PMID- 29180789 TI - The computations that support simple decision-making: A comparison between the diffusion and urgency-gating models. AB - We investigate a question relevant to the psychology and neuroscience of perceptual decision-making: whether decisions are based on steadily accumulating evidence, or only on the most recent evidence. We report an empirical comparison between two of the most prominent examples of these theoretical positions, the diffusion model and the urgency-gating model, via model-based qualitative and quantitative comparisons. Our findings support the predictions of the diffusion model over the urgency-gating model, and therefore, the notion that evidence accumulates without much decay. Gross qualitative patterns and fine structural details of the data are inconsistent with the notion that decisions are based only on the most recent evidence. More generally, we discuss some strengths and weaknesses of scientific methods that investigate quantitative models by distilling the formal models to qualitative predictions. PMID- 29180791 TI - Surface modification of layered perovskite Sr2TiO4 for improved CO2 photoreduction with H2O to CH4. AB - Layered perovskite Sr2TiO4 photocatalyst was synthesized by using sol-gel method with citric acid. In order to increase the surface area of layered perovskite Sr2TiO4, and thus to improve its photocatalytic activity for CO2 reduction, its surface was modified via hydrogen treatment or exfoliation. The physical and chemical properties of the prepared catalysts were characterized by X-ray diffraction, high-resolution transmission electron microscopy, elemental mapping analysis, energy-dispersive X-ray spectroscopy, N2 adsorption-desorption, UV-Vis spectroscopy, X-ray photoelectron spectroscopy, photoluminescence, and electrophoretic light scattering. CO2 photoreduction was performed in a closed reactor under 6 W/cm2 UV irradiation. The gaseous products were analyzed using a gas chromatograph equipped with flame ionization and thermal conductivity detectors. The exfoliated Sr2TiO4 catalyst (E-Sr2TiO4) exhibited a narrow band gap, a large surface area, and high dispersion. Owing to these advantageous properties, E-Sr2TiO4 photocatalyst showed an excellent catalytic performance for CO2 photoreduction reaction. The rate of CH4 production from the photoreduction of CO2 with H2O using E-Sr2TiO4 was about 3431.77 MUmol/gcat after 8 h. PMID- 29180790 TI - Vanillic acid from Actinidia deliciosa impedes virulence in Serratia marcescens by affecting S-layer, flagellin and fatty acid biosynthesis proteins. AB - Serratia marcescens is one of the important nosocomial pathogens which rely on quorum sensing (QS) to regulate the production of biofilm and several virulence factors. Hence, blocking of QS has become a promising approach to quench the virulence of S. marcescens. For the first time, QS inhibitory (QSI) and antibiofilm potential of Actinidia deliciosa have been explored against S. marcescens clinical isolate (CI). A. deliciosa pulp extract significantly inhibited the virulence and biofilm production without any deleterious effect on the growth. Vanillic acid was identified as an active lead responsible for the QSI activity. Addition of vanillic acid to the growth medium significantly affected the QS regulated production of biofilm and virulence factors in a concentration dependent mode in S. marcescens CI, ATCC 14756 and MG1. Furthermore vanillic acid increased the survival of Caenorhabditis elegans upon S. marcescens infection. Proteomic analysis and mass spectrometric identification of differentially expressed proteins revealed the ability of vanillic acid to modulate the expression of proteins involved in S-layers, histidine, flagellin and fatty acid production. QSI potential of the vanillic acid observed in the current study paves the way for exploring it as a potential therapeutic candidate to treat S. marcescens infections. PMID- 29180792 TI - Twitter-derived neighborhood characteristics associated with obesity and diabetes. AB - Neighborhood characteristics are increasingly connected with health outcomes. Social processes affect health through the maintenance of social norms, stimulation of new interests, and dispersal of knowledge. We created zip code level indicators of happiness, food, and physical activity culture from geolocated Twitter data to examine the relationship between these neighborhood characteristics and obesity and diabetes diagnoses (Type 1 and Type 2). We collected 422,094 tweets sent from Utah between April 2015 and March 2016. We leveraged administrative and clinical records on 1.86 million individuals aged 20 years and older in Utah in 2015. Individuals living in zip codes with the greatest percentage of happy and physically-active tweets had lower obesity prevalence-accounting for individual age, sex, nonwhite race, Hispanic ethnicity, education, and marital status, as well as zip code population characteristics. More happy tweets and lower caloric density of food tweets in a zip code were associated with lower individual prevalence of diabetes. Results were robust in sibling random effects models that account for family background characteristics shared between siblings. Findings suggest the possible influence of sociocultural factors on individual health. The study demonstrates the utility and cost effectiveness of utilizing existing big data sources to conduct population health studies. PMID- 29180793 TI - Activation of the mitochondrial unfolded protein response promotes longevity and dopamine neuron survival in Parkinson's disease models. AB - While the pathogenesis of Parkinson's disease (PD) is incompletely understood, mitochondrial dysfunction is thought to play a crucial role in disease pathogenesis. Here, we examined the relationship between mitochondrial function and dopamine neuron dysfunction and death using C. elegans mutants for three mitochondria-related genes implicated in monogenic PD (pdr-1/PRKN, pink-1/PINK1 and djr-1.1/DJ-1). We found that pdr-1 and pink-1 mutants exhibit deficits in dopamine-dependent behaviors, but no loss of dopamine neurons, while djr-1.1 mutants showed an increased sensitivity to oxidative stress. In examining mitochondrial morphology and function, we found that djr-1.1 mutants exhibit increased mitochondrial fragmentation leading to decreased rate of oxidative phosphorylation and ATP levels. pdr-1 and pink-1 mutants show an accumulation of dysfunctional mitochondria with age, which leads to activation of the mitochondrial unfolded protein response (mitoUPR). Preventing the upregulation of the mitoUPR with a deletion in atfs-1 results in decreased lifespan and dopamine neuronal loss in pdr-1 and pink-1 mutants but not in wild-type worms. Overall, our results suggest that mutations in pdr-1 and pink-1 cause the accumulation of dysfunctional mitochondria, which activates the mitoUPR to mitigate the detrimental effect of these mutations on dopamine neuron survival. PMID- 29180794 TI - Water Soluble Self-Aggregates Induced Green Emission of Biocompatible Citric Acid PEG Hyper Branched Polymer. AB - An aliphatic citric acid-PEG hyper-branched polymer (CPHP) with a pi-bond on the polymer backbone was synthesized by a single- step melt reaction in which the polymerization and pi-bond formation occur simultaneously. The chemical structure of CPHP was confirmed by FTIR, 1H-NMR, 13C-NMR and MALDI-TOF mass spectral analyses. Aggregates are generally found to disperse in any solvent but the CPHP aggregates were soluble in water due to their hybrid nature. The pi-bond in the aconitate unit induces green emission by CH/pi interaction while the PEG unit of CPHP increases its solubility in water. The soluble aggregates induced green emission (SAIE) of the CPHP was investigated by UV-Visible absorption and emission spectra, time- correlated single photon counting (TCSPC) and zeta potential measurements. The fluorescence life time (tauf) increased from 4.93 to11.38 ns with an increase in CPHP concentration. The fluorescence quantum yield (Phif) of CPHP can be altered by varying the concentration of CPHP. PMID- 29180795 TI - Hypertension and obesity comorbidities increases coronary risk, affects domains of sexual function and sexual quality of life. AB - About 25% of the world's adult population suffers from arterial hypertension with about 1.5 billion estimated to develop hypertension by 2025. Hypertensive patients have been reported to have a higher risk of developing diabetes and sexual dysfunction. Hypertension have been linked with lubricative and orgasmic difficulties in females, as wel as ED and vascular disease in men. Obesity has also been linked to ED in diabetic males as well as several aspects of female sexuality. Hypertension and obesity are closely related, each occurring in greater frequency with the other, it is only logical to think that comorbidities of obesity and hypertension could increase the risk of cardiovascular disease and SD. This research looks at the relationship between hypertension and obesity comorbidities and its association with sexual function in type II diabetics. Diabetic patients who were at least 18 years old and were engaged in a stable heterosexual relationships for at least 1 year were recruited for this study. Participants were categorized into the -HYP/-OB, +HYP/-OB and the +HYP/+OB groups. Sexual function was assessed using the GRISS-M and GRIS-F for the diabetic males and females respectively. Early morning fasting blood samples was used in lipid profile as well as FBG assay. The Coronary risk was estimated as Total/HDL Cholesterol. Triglyceride levels and coronary risk were highest in the +HYP/+OBES group, followed by the +HYP/-OBES group, with the -HYP/-OBES group recording the lowest levels. PE and infrequency recorded the highest score among the +HYP/+OBES group with the +HYP/-OBES group recording the lowest scores. SQoL was highest amongst the -HYP/-OBES group, with the +HYP/+OBES group recording the lowest scores. Anorgasmia and avoidance increased along the shades of HYP/OBES groups. Comorbidities of hypertension and obesity increases the risk of coronary disease, affects some domains of sexual function and decreases the SQoL of diabetics. PMID- 29180796 TI - Sexual dysfunction as a determinant of cardiovascular outcome in patients undergoing chronic hemodialysis. AB - Sexual dysfunction (SD) is common in men and women with chronic kidney disease (CKD) and is considered as an early marker for cardiovascular (CV) disease. We hypothesized that patients with SD have higher risk for vascular damage of the large arteries, accelerated vascular aging, and consequently higher CV mortality than other end-stage renal disease (ESRD) patients. In this study, the International Index of Erectile Function (IIEF) questionnaire and the Female Sexual Function Index (FSFI) questionnaire were applied in men and women, respectively. Ambulatory blood pressure monitoring (ABPM), arterial stiffness, and ankle-brachial index (ABI) were performed in all patients. Pulse wave velocity (PWV) was significantly slower in non-SD patients (10.5 vs. 8.8 m/s; p < 0.001) with significantly lower number of non-SD patients with PWV > 10 m/s compared to SD patients (p < 0.001). Only 57% of the patients with prior CV event had PWV > 10 m/s. No difference in AIx was observed. Non-SD patients had better values of ABI (0.83 vs. 1.09; p < 0.05) with significantly lower number of non-SD patients with ABI < 0.9 compared to SD patients (p = 0.001) as well as smaller percentage of LVH (57.5% vs. 80.7%; p = 0.01). There were no differences in hemodynamic parameters when patients with SD were divided by sex. Pulse wave velocity was the strongest predictor of lower IIEF and FSFI scores. Mean survival time was longer in non-SD patients than in SD patients (11.6 vs. 10.5 months, p = 0.019). The higher incidence of prior CV events and CV mortality found in SD patients on hemodialysis (HD) is a consequence of accelerated vascular aging. Sexual dysfunction in HD patients should also be considered a marker of subclinical organ damage and future CV events. Our study confirms the predictive role of PWV in HD patients. PMID- 29180797 TI - Outcomes of variation in technique and variation in accuracy of measurement in penile length measurement. AB - Accurate data regarding the size of the erect penis is of great importance to several disciplines working with male patients, but little data exists on the best technique to measure penile length. While some previous small studies have suggested good correlation between stretched penile length, others have shown significant variability. Penile girth has been less well studied, and little data exist on the possible errors induced by differing observers and different techniques. Much of the published data report penile length measured from the penopubic skin junction-to-glans tip (STT) rather than pubic bone-to-tip (BTT). We wished to assess the accuracy of different techniques of penile measurements with multiple observers. Men who achieved full erection using dynamic penile Doppler ultrasound for the diagnosis of sexual dysfunction or a desire for objective penile measurement were included in the study. Exclusion criteria were penile scarring, curvature, or congenital abnormality. In each case, the penis was measured by one of the seven andrology specialists in a private air conditioned (21 degrees C) environment. Each patient had three parameters measured: circumference (girth) of the penile shaft, length from suprapubic skin to-distal glans (STT), and pubis-to-distal glans (BTT). The three measurements were recorded in the stretched flaccid state, and the same three measurements were then repeated in the fully erect state, following induction of full erection with intracavernosal injection. We analyzed the accuracy of each flaccid measurement using the erect measurements as a reference, for the overall patient population and for each observer. In total, 201 adult men (mean age 49.4 years) were included in this study. Assessing the penis in the stretched and flaccid state gave a mean underestimate of the erect measurement of ~20% (STT length 23.39%, BTT length 19.86%, and circumference 21.38%). In this large, multicenter, multi-observer study of penis size, flaccid measurements were only moderately accurate in predicting erect size. They were also significantly observer dependent. Measuring penile length from pubic bone to tip of glans is more accurate and reliable, the discrepancy being most notable in overweight patients. PMID- 29180798 TI - Anthropometric study of penile length in self-declared Brazilians regarding the color of the skin as white or black: The study of a Myth. AB - This is an observational transversal cohort study in which we aim to analyze the Brazilian penis length and compare the penis size of the men self-declared as white (SDW) or black (SDB) skin color. Subjects were asked for self-declare according to their skin color, after that they have been invited to participate in a semi-structured interview so as to have their perception evaluated regarding their penis size and their self-esteem as well. Eventually, their penis length was measured with an anthropometric ruler. The men's mean penis length who declared themselves as black skin color was 16.5 +/- 1.7 cm (penis length in real fully-stretched flaccid length) and the men's mean penis length who declared themselves as white skin color was 15.8 +/- 1.6 cm (p < 0.001).The majority of either SDB (94.0%) or SDW (89.4%) are satisfied with their penis size (p = 0.464). We have shown that the man's mean penis length who identifies himself as black is just a little bit bigger than the one who identifies himself as white. However, there were no significant difference between groups regarding self assessment of genital body image. PMID- 29180799 TI - Low-intensity extracorporeal shock wave therapy for erectile dysfunction after radical prostatectomy: a review of preclinical studies. AB - Low-intensity extracorporeal shock wave therapy (LI-ESWT) is a novel treatment for erectile dysfunction (ED). Its ability to improve erectile function has been shown in patients with vasculogenic ED by many randomized-controlled trials against sham procedures. However, the role of LI-ESWT in ED caused by radical prostatectomy (RP) is still questionable because this type of ED was excluded from nearly all clinical studies; it has been investigated in only a few small single-arm trials. This review summarizes preclinical studies on mechanisms of action of LI-ESWT for ED and neurological diseases to explore the potential of this treatment for nerve-impaired ED after RP. PMID- 29180800 TI - Electronic Health Record Driven Prediction for Gestational Diabetes Mellitus in Early Pregnancy. AB - Gestational diabetes mellitus (GDM) is conventionally confirmed with oral glucose tolerance test (OGTT) in 24 to 28 weeks of gestation, but it is still uncertain whether it can be predicted with secondary use of electronic health records (EHRs) in early pregnancy. To this purpose, the cost-sensitive hybrid model (CSHM) and five conventional machine learning methods are used to construct the predictive models, capturing the future risks of GDM in the temporally aggregated EHRs. The experimental data sources from a nested case-control study cohort, containing 33,935 gestational women in West China Second Hospital. After data cleaning, 4,378 cases and 50 attributes are stored and collected for the data set. Through selecting the most feasible method, the cost parameter of CSHM is adapted to deal with imbalance of the dataset. In the experiment, 3940 samples are used for training and the rest 438 samples for testing. Although the accuracy of positive samples is barely acceptable (62.16%), the results suggest that the vast majority (98.4%) of those predicted positive instances are real positives. To our knowledge, this is the first study to apply machine learning models with EHRs to predict GDM, which will facilitate personalized medicine in maternal health management in the future. PMID- 29180801 TI - Modification and functional adaptation of the MBF1 gene family in the lichenized fungus Endocarpon pusillum under environmental stress. AB - The multiprotein-bridging factor 1 (MBF1) gene family is well known in archaea, non-lichenized fungi, plants, and animals, and contains stress tolerance-related genes. Here, we identified four unique mbf1 genes in the lichenized fungi Endocarpon spp. A phylogenetic analysis based on protein sequences showed the translated MBF1 proteins of the newly isolated mbf1 genes formed a monophyletic clade different from other lichen-forming fungi and Ascomycota groups in general, which may reflect the evolution of the biological functions of MBF1s. In contrast to the lack of function reported in yeast, we determined that lysine114 in the deduced Endocarpon pusillum MBF1 protein (EpMBF1) had a specific function that was triggered by environmental stress. Further, the Endocarpon-specific C terminus of EpMBF1 was found to participate in stress tolerance. Epmbf1 was induced by a number of abiotic stresses in E. pusillum and transgenic yeast, and its stress-resistant ability was stronger than that of the yeast mbf1. These findings highlight the evolution and function of EpMBF1 and provide new insights into the co-evolution hypothesis of MBF1 and TATA-box-binding proteins. PMID- 29180802 TI - Two heart failure phenotypes in arterial hypertension: a clinical study. PMID- 29180803 TI - Prevalence and correlates of hypertension in a semi-rural population of Southern India. AB - While elevated blood pressure is a recognized risk factor for cardiovascular disease, the prevalence of hypertension still remains unclear for most populations. A door-to-door survey was conducted using modified WHO STEPS questionnaire in a group of villages under the Thavanampalle Mandal of Chittoor District in the state of Andhra Pradesh of South India. Data were collated and analyzed for 16,636 individuals (62.3% females and 37.7% males) above 15 years of age. Overall, prevalence of hypertension (as per JNC-7 classification) was found to be 27.0% (95% CI, 26.3, 27.7) in the surveyed community with 56.7% of the total hypertensives being diagnosed for the first time during the survey. An additional 39.1% had their blood pressure readings in the prehypertensive range. Among the known Hypertensives on treatment only 46.2% had a blood pressure recording within acceptable limits, with 31.2% in the prehypertensive range and only 15.0% in the normal range. Systolic blood pressure (SBP) of the surveyed population showed a continuous linear increase with age, but diastolic blood pressure (DBP) peaked and started reducing in early fifth decade in males. Male gender, increasing age, higher body mass index (BMI), increased waist-hip ratio, increased body weight, family history of hypertension, death of spouse, and diabetes were found to be positively correlated with hypertension. Risk factors of alcohol intake, use of ground nut/palm oil, and family history of diabetes lost their independent predictive ability for hypertension on multivariate logistic regression analysis. The level of physical activity was also not found to be a significant predictor of hypertension in the study population. PMID- 29180804 TI - Hypertension prevalence, awareness, treatment, and control in northeast China: a population-based cross-sectional survey. AB - Hypertension has been recognized as a major risk factor for cardiovascular disease. We aimed to analyze the current prevalence, awareness, treatment, and control of hypertension in northeast China. This cross-sectional survey adopted the multistage stratified random cluster sampling method to obtain a representative sample of adults aged 40 years or older in the general population of northeast China. Hypertension was defined as a systolic blood pressure (SBP) >= 140 mm Hg, or diastolic blood pressure (DBP) >= 90 mm Hg, or self-reported use of antihypertensive medications in the last 2 weeks irrespective of BP. Altogether 4052 participants were included with weighted prevalence of hypertension of 57.3%. Among them, 47.4% were aware of their condition; 78.8% took antihypertensive medication, but only 10.2% had their blood pressure controlled. Individuals who were overweight/obesity, with dyslipidemia, or diabetes were at a higher risk of hypertension; these people also more likely to be aware of their condition. Subjects with a personal history of stroke were more inclined to receive antihypertensive medication, but that did not necessarily translate to well-controlled hypertension. Moreover, dyslipidemia (OR = 0.600; 95% CI: 0.375, 0.960) were associated with poor hypertension control. Subjects using combination of antihypertensive medications (OR = 2.924; 95% CI: 1.606, 5.325) or with a family history of coronary heart disease were more likely to have their blood pressure controlled. Our study identified a high prevalence of hypertension in northeast China. Although awareness and treatment rates improved over the last decade, the control rate remained disproportionately and unacceptably low. PMID- 29180805 TI - A fast approach to detect gene-gene synergy. AB - Selecting informative genes, including individually discriminant genes and synergic genes, from expression data has been useful for medical diagnosis and prognosis. Detecting synergic genes is more difficult than selecting individually discriminant genes. Several efforts have recently been made to detect gene-gene synergies, such as dendrogram-based I(X 1; X 2; Y) (mutual information), doublets (gene pairs) and MIC(X 1; X 2; Y) based on the maximal information coefficient. It is unclear whether dendrogram-based I(X 1; X 2; Y) and doublets can capture synergies efficiently. Although MIC(X 1; X 2; Y) can capture a wide range of interaction, it has a high computational cost triggered by its 3-D search. In this paper, we developed a simple and fast approach based on abs conversion type (i.e. Z = |X 1 - X 2|) and t-test, to detect interactions in simulation and real world datasets. Our results showed that dendrogram-based I(X 1; X 2; Y) and doublets are helpless for discovering pair-wise gene interactions, our approach can discover typical pair-wise synergic genes efficiently. These synergic genes can reach comparable accuracy to the individually discriminant genes using the same number of genes. Classifier cannot learn well if synergic genes have not been converted properly. Combining individually discriminant and synergic genes can improve the prediction performance. PMID- 29180806 TI - Rational design of cholesterol oxidase for efficient bioresolution of cholestane skeleton substrates. AB - Cholesterol oxidase catalyzes the oxidation and isomerization of the cholestane substrates leading to the addition of a hydroxyl group at the C3 position. Rational engineering of the cholesterol oxidase from Pimelobacter simplex (PsChO) was performed. Mutagenesis of V64 and F70 improved the catalytic activities toward cholestane substrates. Molecular dynamics simulations, together with structure-activity relationship analysis, revealed that both V64C and F70V increased the binding free energy between PsChO mutants and cholesterol. F70V and V64C mutations might cause the movement of loops L56-P77, K45-P49 and L350-E354 at active site. They enlarged the substrate-binding cavity and relieved the steric interference with substrates facilitating recognition of C17 hydrophobic substrates with long side chain substrates. PMID- 29180807 TI - Viral unmasking of cellular 5S rRNA pseudogene transcripts induces RIG-I-mediated immunity. AB - The sensor RIG-I detects double-stranded RNA derived from RNA viruses. Although RIG-I is also known to have a role in the antiviral response to DNA viruses, physiological RNA species recognized by RIG-I during infection with a DNA virus are largely unknown. Using next-generation RNA sequencing (RNAseq), we found that host-derived RNAs, most prominently 5S ribosomal RNA pseudogene 141 (RNA5SP141), bound to RIG-I during infection with herpes simplex virus 1 (HSV-1). Infection with HSV-1 induced relocalization of RNA5SP141 from the nucleus to the cytoplasm, and virus-induced shutoff of host protein synthesis downregulated the abundance of RNA5SP141-interacting proteins, which allowed RNA5SP141 to bind RIG-I and induce the expression of type I interferons. Silencing of RNA5SP141 strongly dampened the antiviral response to HSV-1 and the related virus Epstein-Barr virus (EBV), as well as influenza A virus (IAV). Our findings reveal that antiviral immunity can be triggered by host RNAs that are unshielded following depletion of their respective binding proteins by the virus.

PMID- 29180808 TI - Engagement of MHC class I by the inhibitory receptor LILRB1 suppresses macrophages and is a target of cancer immunotherapy. AB - Exciting progress in the field of cancer immunotherapy has renewed the urgency of the need for basic studies of immunoregulation in both adaptive cell lineages and innate cell lineages. Here we found a central role for major histocompatibility complex (MHC) class I in controlling the phagocytic function of macrophages. Our results demonstrated that expression of the common MHC class I component beta2 microglobulin (beta2M) by cancer cells directly protected them from phagocytosis. We further showed that this protection was mediated by the inhibitory receptor LILRB1, whose expression was upregulated on the surface of macrophages, including tumor-associated macrophages. Disruption of either MHC class I or LILRB1 potentiated phagocytosis of tumor cells both in vitro and in vivo, which defines the MHC class I-LILRB1 signaling axis as an important regulator of the effector function of innate immune cells, a potential biomarker for therapeutic response to agents directed against the signal-regulatory protein CD47 and a potential target of anti-cancer immunotherapy. PMID- 29180809 TI - Structural basis for TNA synthesis by an engineered TNA polymerase. AB - Darwinian evolution experiments carried out on xeno-nucleic acid (XNA) polymers require engineered polymerases that can faithfully and efficiently copy genetic information back and forth between DNA and XNA. However, current XNA polymerases function with inferior activity relative to their natural counterparts. Here, we report five X-ray crystal structures that illustrate the pathway by which alpha (L)-threofuranosyl nucleic acid (TNA) triphosphates are selected and extended in a template-dependent manner using a laboratory-evolved polymerase known as Kod RI. Structural comparison of the apo, binary, open and closed ternary, and translocated product detail an ensemble of interactions and conformational changes required to promote TNA synthesis. Close inspection of the active site in the closed ternary structure reveals a sub-optimal binding geometry that explains the slow rate of catalysis. This key piece of information, which is missing for all naturally occurring archaeal DNA polymerases, provides a framework for engineering new TNA polymerase variants.

PMID- 29180813 TI - Pollen magnetofection for genetic modification with magnetic nanoparticles as gene carriers. AB - Genetic modification plays a vital role in breeding new crops with excellent traits. Almost all the current genetic modification methods require regeneration from tissue culture, involving complicated, long and laborious processes. In particular, many crop species such as cotton are difficult to regenerate. Here, we report a novel transformation platform technology, pollen magnetofection, to directly produce transgenic seeds without regeneration. In this system, exogenous DNA loaded with magnetic nanoparticles was delivered into pollen in the presence of a magnetic field. Through pollination with magnetofected pollen, transgenic plants were successfully generated from transformed seeds. Exogenous DNA was successfully integrated into the genome, effectively expressed and stably inherited in the offspring. Our system is culture-free and genotype independent. In addition, it is simple, fast and capable of multi-gene transformation. We envision that pollen magnetofection can transform almost all crops, greatly facilitating breeding processes of new varieties of transgenic crops. PMID- 29180814 TI - The crystal structure of Deg9 reveals a novel octameric-type HtrA protease. AB - The high temperature requirement A (HtrA) proteases (also termed Deg proteases) play important roles in diverse organisms by regulating protein quality and quantity. One of the 16 Arabidopsis homologs, Deg9, is located in the nucleus where it modulates cytokinin- and light-mediated signalling via degrading the ARABIDOPSIS RESPONSE REGULATOR 4 (ARR4). To uncover the structural features underlying the proteolytic activity of Deg9, we determined its crystal structure. Unlike the well-established trimeric building block of HtrAs, Deg9 displays a novel octameric structure consisting of two tetrameric rings that have distinct conformations. Based on the structural architecture, we generated several mutant variants of Deg9, determined their structure and tested their proteolytic activity towards ARR4. The results of the structural and biochemical analyses allowed us to propose a model for a novel mechanism of substrate recognition and activity regulation of Deg9. In this model, protease activation of one tetramer is mediated by en-bloc reorientation of the protease domains to open an entrance for the substrate in the opposite (inactive) tetramer. This study provides the structural basis for understanding how the levels of nuclear signal components are regulated by a plant protease. PMID- 29180815 TI - Non-specific activities of the major herbicide-resistance gene BAR. AB - Bialaphos resistance (BAR) and phosphinothricin acetyltransferase (PAT) genes, which convey resistance to the broad-spectrum herbicide phosphinothricin (also known as glufosinate) via N-acetylation, have been globally used in basic plant research and genetically engineered crops 1-4 . Although early in vitro enzyme assays showed that recombinant BAR and PAT exhibit substrate preference toward phosphinothricin over the 20 proteinogenic amino acids 1 , indirect effects of BAR-containing transgenes in planta, including modified amino acid levels, have been seen but without the identification of their direct causes 5,6 . Combining metabolomics, plant genetics and biochemical approaches, we show that transgenic BAR indeed converts two plant endogenous amino acids, aminoadipate and tryptophan, to their respective N-acetylated products in several plant species. We report the crystal structures of BAR, and further delineate structural basis for its substrate selectivity and catalytic mechanism. Through structure-guided protein engineering, we generated several BAR variants that display significantly reduced non-specific activities compared with its wild-type counterpart in vivo. The transgenic expression of enzymes can result in unintended off-target metabolism arising from enzyme promiscuity. Understanding such phenomena at the mechanistic level can facilitate the design of maximally insulated systems featuring heterologously expressed enzymes. PMID- 29180817 TI - Virus replicon particle vaccines expressing nucleoprotein of influenza A virus mediate enhanced inflammatory responses in pigs. AB - Studies in the mouse model indicate that the nucleoprotein of influenza A virus represents an interesting vaccine antigen being well conserved across subtypes of influenza virus but still able to induce protective immune responses. Here we show that immunizations of pigs with vesicular stomatitis virus- and classical swine fever virus-derived replicon (VRP) particles expressing the nucleoprotein (NP) of H1N1 A/swine/Belzig/2/01 induced potent antibody and T-cell responses against influenza A virus. In contrast to a conventional whole inactivated virus vaccine, the VRP vaccines induced both NP-specific CD4 and CD8 T cells responses, including interferon-gamma and tumor-necrosis-factor dual-secreting cell. Although T-cells and antibody responses were cross-reactive with the heterologous H1N2 A/swine/Bakum/R757/2010 challenge virus, they did not provide protection against infection. Surprisingly, vaccinated pigs showed enhanced virus shedding, lung inflammation and increased levels of systemic and lung interferon-alpha as well as elevated lung interleukin-6. In conclusion, our study shows that NP, although efficacious in the mouse model, appears not to be a promising stand alone vaccine antigen for pigs. PMID- 29180818 TI - OCT4 supports extended LIF-independent self-renewal and maintenance of transcriptional and epigenetic networks in embryonic stem cells. AB - Embryonic stem (ES) cell pluripotency is governed by OCT4-centric transcriptional networks. Conventional ES cells can be derived and maintained in vitro with media containing the cytokine leukemia inhibitory factor (LIF), which propagates the pluripotent state by activating STAT3 signaling, and simultaneous inhibition of glycogen synthase kinase-3 (GSK3) and MAP kinase/ERK kinase signaling. However, it is unclear whether overexpression of OCT4 is sufficient to overcome LIF dependence. Here, we show that inducible expression of OCT4 (iOCT4) supports long term LIF-independent self-renewal of ES cells cultured in media containing fetal bovine serum (FBS) and a glycogen synthase kinase-3 (GSK3) inhibitor, and in serum-free media. Global expression analysis revealed that LIF-independent iOCT4 ES cells and control ES cells exhibit similar transcriptional programs relative to epiblast stem cells (EpiSCs) and differentiated cells. Epigenomic profiling also demonstrated similar patterns of histone modifications between LIF independent iOCT4 and control ES cells. Moreover, LIF-independent iOCT4 ES cells retain the capacity to differentiate in vitro and in vivo upon downregulation of OCT4 expression. These findings indicate that OCT4 expression is sufficient to sustain intrinsic signaling in a LIF-independent manner to promote ES cell pluripotency and self-renewal. PMID- 29180819 TI - Quantum-disordered state of magnetic and electric dipoles in an organic Mott system. AB - Strongly enhanced quantum fluctuations often lead to a rich variety of quantum disordered states. Developing approaches to enhance quantum fluctuations may open paths to realize even more fascinating quantum states. Here, we demonstrate that a coupling of localized spins with the zero-point motion of hydrogen atoms, that is, proton fluctuations in a hydrogen-bonded organic Mott insulator provides a different class of quantum spin liquids (QSLs). We find that divergent dielectric behavior associated with the approach to hydrogen-bond order is suppressed by the quantum proton fluctuations, resulting in a quantum paraelectric (QPE) state. Furthermore, our thermal-transport measurements reveal that a QSL state with gapless spin excitations rapidly emerges upon entering the QPE state. These findings indicate that the quantum proton fluctuations give rise to a QSL-a quantum-disordered state of magnetic and electric dipoles-through the coupling between the electron and proton degrees of freedom. PMID- 29180820 TI - Subcutaneous white adipocytes express a light sensitive signaling pathway mediated via a melanopsin/TRPC channel axis. AB - Subcutaneous white adipose tissue (scWAT) is the major fat depot in humans and is a central player in regulating whole body metabolism. Skin exposure to UV wavelengths from sunlight is required for Vitamin D synthesis and pigmentation, although it is plausible that longer visible wavelengths that penetrate the skin may regulate scWAT function. In this regard, we discovered a novel blue light sensitive current in human scWAT that is mediated by melanopsin coupled to transient receptor potential canonical cation channels. This pathway is activated at physiological intensities of light that penetrate the skin on a sunny day. Daily exposure of differentiated adipocytes to blue light resulted in decreased lipid droplet size, increased basal lipolytic rate and alterations in adiponectin and leptin secretion. Our results suggest that scWAT function may be directly under the influence of ambient sunlight exposure and may have important implications for our current understanding of adipocyte biology.

Part of the current development in stroke therapy is focused in the chronic phase, where neurorepair mechanisms such as neurogenesis, are involved. In the adult brain, one of the regions where neurogenesis takes place is the subventricular zone (SVZ) of the lateral ventricles. Given the possibility to develop pharmacological therapies to stimulate this process, we have performed a longitudinal analysis of neurogenesis in a model of cortical ischemia in mice. Our results show an initial decrease of SVZ proliferation at 24 h, followed by a recovery leading to an increase at 14d and a second decrease 28d after stroke. Coinciding with the 24 h proliferation decrease, an increase in the eutopic neuroblast migration towards the olfactory bulb was observed. The analysis of the neuroblast ectopic migration from the SVZ toward the lesion showed an increase in this process from day 14 after the insult. Finally, our data revealed an increased number of new cortical neurons in the peri-infarct cortex 65d after the insult. In summary, we report here critical check-points about post-stroke neurogenesis after cortical infarcts, important for the pharmacological modulation of this process in stroke patients. PMID- 29180822 TI - Damage-induced lncRNAs control the DNA damage response through interaction with DDRNAs at individual double-strand breaks. AB - The DNA damage response (DDR) preserves genomic integrity. Small non-coding RNAs termed DDRNAs are generated at DNA double-strand breaks (DSBs) and are critical for DDR activation. Here we show that active DDRNAs specifically localize to their damaged homologous genomic sites in a transcription-dependent manner. Following DNA damage, RNA polymerase II (RNAPII) binds to the MRE11-RAD50-NBS1 complex, is recruited to DSBs and synthesizes damage-induced long non-coding RNAs (dilncRNAs) from and towards DNA ends. DilncRNAs act both as DDRNA precursors and by recruiting DDRNAs through RNA-RNA pairing. Together, dilncRNAs and DDRNAs fuel DDR focus formation and associate with 53BP1. Accordingly, inhibition of RNAPII prevents DDRNA recruitment, DDR activation and DNA repair. Antisense oligonucleotides matching dilncRNAs and DDRNAs impair site-specific DDR focus formation and DNA repair. We propose that DDR signalling sites, in addition to sharing a common pool of proteins, individually host a unique set of site specific RNAs necessary for DDR activation. PMID- 29180823 TI - HUWE1 variants cause dominant X-linked intellectual disability: a clinical study of 21 patients. AB - Whole-gene duplications and missense variants in the HUWE1 gene (NM_031407.6) have been reported in association with intellectual disability (ID). Increased gene dosage has been observed in males with non-syndromic mild to moderate ID with speech delay. Missense variants reported previously appear to be associated with severe ID in males and mild or no ID in obligate carrier females. Here, we report the largest cohort of patients with HUWE1 variants, consisting of 14 females and 7 males, with 15 different missense variants and one splice site variant. Clinical assessment identified common clinical features consisting of moderate to profound ID, delayed or absent speech, short stature with small hands and feet and facial dysmorphism consisting of a broad nasal tip, deep set eyes, epicanthic folds, short palpebral fissures, and a short philtrum. We describe for the first time that females can be severely affected, despite preferential inactivation of the affected X chromosome. Three females with the c.329 G > A p.Arg110Gln variant, present with a phenotype of mild ID, specific facial features, scoliosis and craniosynostosis, as reported previously in a single patient. In these females, the X inactivation pattern appeared skewed in favour of the affected transcript. In summary, HUWE1 missense variants may cause syndromic ID in both males and females.

AB - Detecting enemies is crucial for survival and a trait that develops over an evolutionary timeframe. Introduced species disrupt coevolved systems of communication and detection in their new ranges, often leading to devastating impacts. The classic example is prey naivety towards alien predators, whereby prey fail to recognise a new predator. Yet exactly why native prey fail to recognise alien predators remains puzzling. Naivety theory predicts that it is because novel predators emit novel cues. Distantly related animals have distinct evolutionary histories, physiologies and ecologies, predicting they will emit different cues. Yet it also possible that all predators emit similar cues because they are carnivorous. We investigate whether odour cues differ between placental and marsupial carnivores in Australia, where native prey experienced only marsupial mammal predation until ~4000 years ago. We compared volatile chemical profiles of urine, scats and bedding from four placental and three marsupial predators. Chemical profiles showed little overlap between placental and marsupial carnivores across all odour types, suggesting that cue novelty is a plausible mechanism for prey naivety towards alien predators. Our results also suggest a role for olfactory cues to complement visual appearance and vocalisations as biologically meaningful ways to differentiate species. PMID- 29180824 TI - Genetic Architecture and Candidate Genes Identified for Follicle Number in Chicken. AB - Follicular development has a major impact on reproductive performance. Most previous researchers focused on molecular mechanisms of follicular development. The genetic architecture underlying the number of follicle, however, has yet not to be thoroughly defined in chicken. Here we report a genome-wide association study for the genetic architecture determining the numbers of follicles in a large F2 resource population. The results showed heritability were low to moderate (0.05-0.28) for number of pre-ovulatory follicles (POF), small yellow follicles (SYF) and atresia follicles (AF). The highly significant SNPs associated with SYF were mainly located on GGA17 and GGA28. Only four significant SNPs were identified for POF on GGA1. The variance partitioned across chromosomes and chromosome lengths had a linear relationship for SYF (R2 = 0.58). The enriched genes created by the closest correspondent significant SNPs were found to be involved in biological pathways related to cell proliferation, cell cycle and cell survival. Two promising candidate genes, AMH and RGS3, were suggested to be prognostic biomarkers for SYF. In conclusion, this study offers the first evidence of genetic variance and positional candidate genes which influence the number of SYF in chicken. These identified informative SNPs may facilitate selection for an improved reproductive performance of laying hens. PMID- 29180826 TI - Persistent inhibition of pore-based cell migration by sub-toxic doses of miuraenamide, an actin filament stabilizer. AB - Opposed to tubulin-binding agents, actin-binding small molecules have not yet become part of clinical tumor treatment, most likely due to the fear of general cytotoxicity. Addressing this problem, we investigated the long-term efficacy of sub-toxic doses of miuraenamide, an actin filament stabilizing natural compound, on tumor cell (SKOV3) migration. No cytotoxic effects or persistent morphological changes occurred at a concentration of miuraenamide of 20 nM. After 72 h treatment with this concentration, nuclear stiffness was increased, causing reduced migration through pores in a Boyden chamber, while cell migration and chemotaxis per se were unaltered. A concomitant time-resolved proteomic approach showed down regulation of a protein cluster after 56 h treatment. This cluster correlated best with the Wnt signaling pathway. A further analysis of the actin associated MRTF/SRF signaling showed a surprising reduction of SRF-regulated proteins. In contrast to acute effects of actin-binding compounds on actin at high concentrations, long-term low-dose treatment elicits much more subtle but still functionally relevant changes beyond simple destruction of the cytoskeleton. These range from biophysical parameters to regulation of protein expression, and may help to better understand the complex biology of actin, as well as to initiate alternative regimes for the testing of actin-targeting drugs. PMID- 29180827 TI - Development and Validation of High Performance Liquid Chromatographic Method for Determination of Gentisic Acid and Related Renal Cell Carcinoma Biomarkers in Urine. AB - A reversed phase liquid chromatographic (RPLC) method was developed to simultaneously detect and quantify creatinine, quinolinic acid, gentisic acid and 4-hydroxybenzoic acid in urine. These four bio-markers are present in relatively high concentrations in urine. Using a 5% methanol in water mobile phase with 0.6% acetic acid and a Zorbax C18 column, baseline resolution for all four biomarkers in synthetic urine was achieved. Better resolution was obtained for the separation of these four compounds when water rich mobile phases were used. Detection of the four biomarkers in urine using the proposed RPLC method is limited by background from the urine matrix for the later eluting compounds and from the dead marker for earlier eluting compounds. PMID- 29180828 TI - Plant litter functional diversity effects on litter mass loss depend on the macro detritivore community. AB - A better understanding of the mechanisms driving litter diversity effects on decomposition is needed to predict how biodiversity losses affect this crucial ecosystem process. In a microcosm study, we investigated the effects of litter functional diversity and two major groups of soil macro-detritivores on the mass loss of tree leaf litter mixtures. Furthermore, we tested the effects of litter trait community means and dissimilarity on litter mass loss for seven traits relevant to decomposition. We expected macro-detritivore effects on litter mass loss to be most pronounced in litter mixtures of high functional diversity. We used 24 leaf mixtures differing in functional diversity, which were composed of litter from four species from a pool of 16 common European tree species. Earthworms, isopods, or a combination of both were added to each litter combination for two months. Litter mass loss was significantly higher in the presence of earthworms than in that of isopods, whereas no synergistic effects of macro-detritivore mixtures were found. The effect of functional diversity of the litter material was highest in the presence of both macro-detritivore groups, supporting the notion that litter diversity effects are most pronounced in the presence of different detritivore species. Species-specific litter mass loss was explained by nutrient content, secondary compound concentration, and structural components. Moreover, dissimilarity in N concentrations increased litter mass loss, probably because detritivores having access to nutritionally diverse food sources. Furthermore, strong competition between the two macro-detritivores for soil surface litter resulted in a decrease of survival of both macro detritivores. These results show that the effects of litter functional diversity on decomposition are contingent upon the macro-detritivore community and composition. We conclude that the temporal dynamics of litter trait diversity effects and their interaction with detritivore diversity are key to advancing our understanding of litter mass loss in nature. PMID- 29180829 TI - Automated detection of geological landforms on Mars using Convolutional Neural Networks. AB - The large volume of high-resolution images acquired by the Mars Reconnaissance Orbiter has opened a new frontier for developing automated approaches to detecting landforms on the surface of Mars. However, most landform classifiers focus on crater detection, which represents only one of many geological landforms of scientific interest. In this work, we use Convolutional Neural Networks (ConvNets) to detect both volcanic rootless cones and transverse aeolian ridges. Our system, named MarsNet, consists of five networks, each of which is trained to detect landforms of different sizes. We compare our detection algorithm with a widely used method for image recognition, Support Vector Machines (SVMs) using Histogram of Oriented Gradients (HOG) features. We show that ConvNets can detect a wide range of landforms and has better accuracy and recall in testing data than traditional classifiers based on SVMs. PMID- 29180831 TI - Internal conflict, market uniformity, and transparency in price competition between teams. AB - The way profits are divided within successful teams imposes different degrees of internal conflict. We experimentally examine how the level of internal conflict, and whether such conflict is transparent to other teams, affects teams' ability to compete vis-a-vis each other, and, consequently, market outcomes. Participants took part in a repeated Bertrand duopoly game between three-player teams which had either the same or different level of internal conflict (uniform vs. mixed). Profit division was either private-pay (high conflict; each member received her own asking price) or equal-pay (low conflict; profits were divided equally). We find that internal conflict leads to (tacit) coordination on high prices in uniform private-pay duopolies, but places private-pay teams at a competitive disadvantage in mixed duopolies. Competition is softened by transparency in uniform markets, but intensified in mixed markets. We propose an explanation of the results and discuss implications for managers and policy makers.

AB - The Mycosphaerellaceae represent thousands of fungal species that are associated with diseases on a wide range of plant hosts. Understanding and stabilising the taxonomy of genera and species of Mycosphaerellaceae is therefore of the utmost importance given their impact on agriculture, horticulture and forestry. Based on previous molecular studies, several phylogenetic and morphologically distinct genera within the Mycosphaerellaceae have been delimited. In this study a multigene phylogenetic analysis (LSU, ITS and rpb2) was performed based on 415 isolates representing 297 taxa and incorporating ex-type strains where available. The main aim of this study was to resolve the phylogenetic relationships among the genera currently recognised within the family, and to clarify the position of the cercosporoid fungi among them. Based on these results many well-known genera are shown to be paraphyletic, with several synapomorphic characters that have evolved more than once within the family. As a consequence, several old generic names including Cercosporidium, Fulvia, Mycovellosiella, Phaeoramularia and Raghnildiana are resurrected, and 32 additional genera are described as new. Based on phylogenetic data 120 genera are now accepted within the family, but many currently accepted cercosporoid genera still remain unresolved pending fresh collections and DNA data. The present study provides a phylogenetic framework for future taxonomic work within the Mycosphaerellaceae. PMID- 29180832 TI - Emotion Language in Trauma Narratives is Associated with Better Psychological Adjustment among Survivors of Childhood Sexual Abuse. AB - Traumatized individuals are often encouraged to confront their experiences by talking or writing about them. However, survivors of childhood sexual abuse (CSA) might find it especially difficult to process abuse experiences, particularly when the abuse is more severe, which could put them at greater risk for mental health problems. The current study examined whether CSA survivors who use emotion language when describing their abuse experiences exhibit better mental health. We analyzed the trauma narratives of 55 adults who, as children, were part of a larger study of the long-term emotional effects of criminal prosecutions on CSA survivors. Abuse narratives were analyzed using the Linguistic Inquiry and Word Count (LIWC) program. We examined whether positive and negative emotion language in participants' abuse narratives were associated with self- and caregiver reported mental health symptoms and whether these associations differed according to the severity of the abuse. As hypothesized, participants who used more positive and negative emotion language had better psychological outcomes, especially when the abuse was severe. Our findings suggest that survivors of more severe abuse might benefit from including emotion language, whether positive or negative in valence, when describing the abuse. PMID- 29180833 TI - Growth Differentiation Factor-15 Is a Predictor of Mortality in Critically Ill Patients with Sepsis. AB - Growth differentiation factor-15 (GDF-15) is a member of the transforming growth factor-beta superfamily related to inflammation and macrophage activation. Serum concentrations of GDF-15 can predict poor survival in chronic diseases, but its role in sepsis is obscure. Therefore, we investigated GDF-15 as a prognostic biomarker in critically ill patients. We measured GDF-15 levels in 219 critically ill patients (146 with sepsis, 73 without sepsis) upon admission to the intensive care unit (ICU), in comparison to 66 healthy controls. GDF-15 levels were significantly increased in ICU patients compared to controls. GDF-15 was further increased in sepsis and showed a strong association with organ dysfunction (kidney, liver and lactate) and disease severity (APACHE II and SOFA score). High GDF-15 concentrations at admission independently predicted ICU (HR 3.42; 95% CI 1.33-8.78) and overall mortality (HR 2.02, 95% CI 1.02-3.88) in all ICU critically ill patients as well as in a large subgroup of sepsis patients (ICU mortality: HR 3.16; 95% CI 1.10-9.07; overall mortality: HR 2.62; 95% CI 1.14 6.02). Collectively, serum GDF-15 levels are significantly increased in critically ill patients, associated with sepsis, organ failure, and disease severity. High GDF-15 levels at ICU admission predict short- and long-term mortality risk. PMID- 29180834 TI - Increased Levels of S100A8/A9 in Patients with Peritonsillar Abscess: A New Promising Diagnostic Marker to Differentiate between Peritonsillar Abscess and Peritonsillitis. AB - Peritonsillar abscess (PTA) is a very frequent reason for urgent outpatient consultation and otolaryngological hospital admission. Early, correct diagnosis and therapy of peritonsillar abscess are important to prevent possible life threatening complications. Based on physical examinations, a reliable differentiation between peritonsillar cellulitis and peritonsillar abscess is restricted. A heterodimeric complex called calprotectin consists of the S100 proteins A8 and A9 (S100A8/A9) and is predominantly expressed not only in monocytes and neutrophils but also in epithelial cells. Due to its release by activated phagocytes at local sites of inflammation, we assumed S100A8/A9 to be a potential biomarker for peritonsillar abscess. We examined serum and saliva of patients with peritonsillitis, acute tonsillitis, peritonsillar abscess, and healthy controls and found significantly increased levels of S100A8/A9 in patients with PTA. Furthermore, we could identify halitosis, trismus, uvula edema, and unilateral swelling of the arched palate to be characteristic symptoms for PTA. Using a combination of these characteristic symptoms and S100A8/A9 levels, we developed a PTA score as an objective and appropriate tool to differentiate between peritonsillitis and peritonsillar abscess with a sensitivity of 92% and specificity of 93%. PMID- 29180835 TI - Laminated and infused Parafilm(r) - paper for paper-based analytical devices. AB - Numerous fabrication methods have been reported for microfluidic paper-based analytical devices (MUPADs) using barrier materials ranging from photoresist to wax. While these methods have been used with wide success, consistently producing small, high-resolution features using materials and methods that are compatible with solvents and surfactants remains a challenge. Two new methods are presented here for generating MUPADs with well-defined, high-resolution structures compatible with solvents and surfactant-containing solutions by partially or fully fusing paper with Parafilm(r) followed by cutting with a CO2 laser cutter. Partial fusion leads to laminated paper (l-paper) while the complete fusion results in infused paper (i-paper). Patterned structures in l-paper were fabricated by selective removal of the paper but not the underlying Parafilm(r) using a benchtop CO2 laser. Under optimized conditions, a gap as small as 137 +/- 22 MUm could be generated. Using this approach, a miniaturized paper 384-zone plate, consisting of circular detection elements with a diameter of 1.86 mm, was fabricated in 64 * 43 mm2 area. Furthermore, these ablation-patterned substrates were confirmed to be compatible with surfactant solutions and common organic solvents (methanol, acetonitrile and dimethylformamide), which has been achieved by very few MUPAD patterning techniques. Patterns in i-paper were created by completely cutting out zones of the i-paper and then fixing pre-cut paper into these openings similar to the strategy of fitting a jigsaw piece into a puzzle. Upon heating, unmodified paper was readily sealed into these openings due to partial reflow of the paraffin into the paper. This unique and simple bonding method was illustrated by two types of 3D MUPADs, a push-on valve and a time gated flow distributor, without adding adhesive layers. The free-standing jigsaw patterned sheets showed good structural stability and solution compatibility, which provided a facile alternative method for fabricating complicated MUPADs. PMID- 29180837 TI - IL-33-ST2 Axis in Liver Disease: Progression and Challenge. AB - The new member of the IL-1 family, interleukin-33 (IL-33), participates in the progression of a variety of diseases through binding with its receptor ST2. Recently, much clinical evidence and experimental data have indicated that IL-33 is associated with various liver diseases. This review primarily addresses the relationship between IL-33 and several hepatic diseases. IL-33 can alleviate high fat diet- (HFD-) induced hepatic steatosis and insulin resistance, and IL-33 acts as an alarmin, which quickly triggers the immune system to respond to virus invasion and toxic damage to the liver. However, when liver injury is chronic, IL 33 promotes Th2 reactions and hepatic stellate cell (HSC) activity, facilitating progression to liver fibrosis. The complicated functions of IL-33 should be considered before its clinical application. PMID- 29180836 TI - Skin Immune Landscape: Inside and Outside the Organism. AB - The skin is an essential organ to the human body protecting it from external aggressions and pathogens. Over the years, the skin was proven to have a crucial immunological role, not only being a passive protective barrier but a network of effector cells and molecular mediators that constitute a highly sophisticated compound known as the "skin immune system" (SIS). Studies of skin immune sentinels provided essential insights of a complex and dynamic immunity, which was achieved through interaction between the external and internal cutaneous compartments. In fact, the skin surface is cohabited by microorganisms recognized as skin microbiota that live in complete harmony with the immune sentinels and contribute to the epithelial barrier reinforcement. However, under stress, the symbiotic relationship changes into a dysbiotic one resulting in skin disorders. Hence, the skin microbiota may have either positive or negative influence on the immune system. This review aims at providing basic background information on the cutaneous immune system from major cellular and molecular players and the impact of its microbiota on the well-coordinated immune responses in host defense. PMID- 29180838 TI - Suppressed Programmed Death 1 Expression on CD4+ and CD8+ T Cells in Psoriatic Patients. AB - Psoriasis is a chronic inflammatory disease mediated by T cell immunity. Programmed death 1 (PD-1), a coinhibitory receptor, plays an important role in immune regulation and maintaining peripheral tolerance. The aim of the study was to compare the expression of PD-1 on the peripheral T cells between psoriatic patients and healthy controls. The study included 75 psoriatic patients and 52 healthy volunteers. The percentages and absolute numbers of CD3+, CD4+, CD8+, CD4+PD-1+, and CD8+PD-1+ T cells were analyzed using flow cytometry. The absolute numbers and percentages of CD4+PD-1+ and CD8+PD-1+ T cells were significantly decreased in the psoriatic patients in comparison with the control group. No significant correlations were found between the absolute numbers and percentages of CD4+PD-1+ or CD8+PD-1+ T cells and clinical characteristics of psoriasis. Decreased PD-1 expression on the T cells may be responsible for impaired negative regulation of immune response in psoriasis pathogenesis. PMID- 29180839 TI - Triggering Receptor Expressed on Myeloid Cells 2 Overexpression Inhibits Proinflammatory Cytokines in Lipopolysaccharide-Stimulated Microglia. AB - Microglia play an important role in mediating inflammatory processes in the central nervous system (CNS). Triggering receptor expressed on myeloid cells 2 (TREM2) is a microglia-specific receptor and could decrease neuropathology in Alzheimer's disease (AD). However, the detailed mechanism remains unclear. This study was designed to elucidate the effect of TREM2 on microglia. We showed that lipopolysaccharide (LPS) stimulation significantly increases proinflammatory cytokines and suppressed TREM2 in microglia. In addition, TREM2 overexpression inhibited LPS-induced microglia activation and elevated M2 phenotype of microglia. Together, our results demonstrate that TREM2 overexpression reduced LPS-induced proinflammatory cytokine release in microglia and increased M2 phenotype of microglia. These findings provide novel insights that the regulation of microglia polarization may be an approach for ameliorating microglia inflammation in neurodegenerative diseases. PMID- 29180841 TI - The Role of EUS-BD in the Management of Malignant Biliary Obstruction: The Indonesian Perspective. AB - Aims: To evaluate the success rate and related factors of endoscopic ultrasound guided-biliary drainage (EUS-BD). Material and Methods: We conducted a retrospective study among 24 patients with malignant biliary obstruction who underwent EUS-BD after failed ERCP from January 2015 to December 2016 in a tertiary health center. The bilirubin levels before and after the procedure were used to define the clinical success rate, while the stent deployment was used to define the technical success rate. We placed either transluminal biliary stents or transpapillary biliary stents. Results: Among 24 patients, choledochoduodenostomy technique was conducted in 23 patients (95.8%) and hepaticogastrostomy technique in 1 patient (4.2%). Transluminal stent placement was conducted in 23 patients, while transpapillary stent placement was conducted in 1 patient. The clinical success rate was 78.2% (18) in choledochoduodenostomy route and 100% (1) in hepaticogastrostomy route. EUS-BD was 2.37 times and 2.11 times more likely to be successful in reducing the bilirubin level in patients with tumor of the head of pancreas and periampullary tumor, respectively, but not in cholangiocarcinoma. Conclusions: EUS-BD is an effective and efficient procedure to achieve biliary drainage among patients with malignant biliary obstruction after ERCP failure. PMID- 29180840 TI - Candida Chorioamnionitis Leads to Preterm Birth and Adverse Fetal-Neonatal Outcome. AB - Candida chorioamnionitis is rare but can lead to neonatal infection, high mortality, and neurodevelopmental impairment. We aimed to investigate maternal clinical features and perinatal outcomes and discuss future management strategies. We reviewed the medical records of women with Candida chorioamnionitis at our hospital over a 10-year period (n = 9) and previous published case reports and case series. The most prevalent Candida species was C. albicans (71.3% of the all cases). The most prevalent predisposing condition was preterm premature rupture of membranes (31/123, 25.2%), followed by pregnancy with a retained intrauterine contraceptive device (26/123, 21.1%) and pregnancy after in vitro fertilization (25/123, 20.3%). Preterm labor was the most common symptom (52/123, 42.3%), and only 13% of cases involved fever. Of the infants, 27% of the singletons and 23.8% of the twins were born before 22 gestational weeks, while 60% of the singletons and 76.2% of the twins were born at 22-36 weeks. The median birth weight of the babies born after 22 weeks was 1230 g. The mortality rates of the singletons and twins born after 22 weeks of gestation in the year 2000 or later were 28.6% and 52.4%, respectively. Antenatal treatment for Candida chorioamnionitis has not been established. PMID- 29180842 TI - Feasibility and Acceptability of Two Complementary and Alternative Therapies for Perceived Insufficient Milk in Mothers of Late Preterm and Early Term Infants. AB - Background: Complementary and alternative medicine (CAM) could be one option to address perceived insufficient milk (PIM), but there are few data comparing the effectiveness, acceptability, and safety of various CAM therapies. The purpose of this study was to describe and compare, among women delivering at 34-376/7 weeks, the feasibility and acceptability of two CAM interventions for treatment of PIM: (1) a meditation/relaxation intervention via an MP3 (Apple iPod Shuffle(c)) player and (2) a commercially available combination-blend herbal supplement (Motherlove: More Milk Plus Alcohol Free(r)). Materials and Methods: After randomization, over 9 days, women received three home visits from a lactation consultant, recorded pre/post intervention test weights and expressed milk volume, tracked daily breastfeeding behavior, and completed an end-of-study interview about the interventions. Women in each group were offered the other group's intervention on study day 9. Breastfeeding status and intervention continuation were assessed at 2 months. Results: Of 183 women screened, 11 were eligible, enrolled into, and completed the 9-day trial. Six women were randomized to the herbal supplement and 5 to meditation. One participant (meditation) stopped breastfeeding on study day 8. At 2 months, 3 of 6 women assigned to the herbal supplement and 3 of 5 women assigned to meditation were still breastfeeding; 1 (herbal supplement) was exclusively breastfeeding. Most participants were adherent to the prescribed protocols for both interventions. Interventions were generally perceived as safe, with benefits not necessarily related to increased milk supply. Conclusion: Mothers of late preterm and early term infants who had PIM found the CAM interventions acceptable and safe. The effect of CAM therapies on breastfeeding outcomes, with and without in-home lactation assistance, requires further investigation. PMID- 29180843 TI - Visual performance, reading ability and patient satisfaction after implantation of a diffractive trifocal intraocular lens. AB - Purpose: To evaluate visual outcome, reading performance, contrast sensitivity, and patient satisfaction after cataract surgery with implantation of a diffractive trifocal intraocular lens (IOL). Patients and methods: A total of 42 eyes (21 patients) underwent cataract surgery with implantation of the trifocal IOL AT LISA tri 839MP. Visual acuity, contrast sensitivity, and patient satisfaction were evaluated 3 months postoperatively. Reading performance was evaluated at 3 months postoperatively with the MNREAD charts. Results: All eyes achieved a 3-month postoperative monocular uncorrected distance visual acuity of 0.10 logMAR or better (Snellen 20/25). Likewise, 97.62% and 85.71% of eyes achieved a postoperative monocular uncorrected intermediate, and near visual acuity of 0.20 logMAR (Snellen 20/30) or better. All patients achieved postoperative binocular uncorrected distance visual acuity, uncorrected intermediate, and uncorrected near visual acuity of 0.20 logMAR (Snellen 20/30) or better. Mean photopic reading acuity and speed were 0.24+/-0.07 logMAR and 177.61+/-20.67 words per minute, respectively. Postoperative contrast sensitivity values were within the ranges of normality for all spatial frequencies evaluated. Postoperative spectacle independence and patient satisfaction was very high, with most of the patients reporting a good or very good visual quality at far, intermediate, and near distances. All patients would choose the same lens again. Conclusion: The evaluated trifocal IOL provides an effective restoration of the visual function after cataract surgery, with high levels of distance, intermediate, and near visual acuity, strong reading performance, and patient satisfaction. PMID- 29180844 TI - Vitreoretinal interface abnormalities in diabetic macular edema and effectiveness of anti-VEGF therapy: an optical coherence tomography study. AB - Purpose: To study vitreoretinal interface (VRI) abnormalities in diabetic macular edema (DME) and the influence of these on the effectiveness of intravitreal anti vascular endothelial growth factor (VEGF) therapy. Methods: VRI status and central retinal thickness (CRT) were evaluated using line and 3D-reference scans obtained using spectral domain-optical coherence tomography RTVue-100 before and 1 month after intravitreal anti-VEGF injection (IVI). VRI status was categorized into five subgroups: normal VRI, retinal surface wrinkling associated with the eccentric epiretinal membrane (ERM), ERM involving the macular center, vitreomacular adhesion (VMA), and vitreomacular traction (VMT). Results: A total of 105 eyes of 89 patients were included in the study. One month after IVI, the mean change of CRT in normal VRI eyes and eyes with VRI abnormalities was 128.0+/-144.7 um and -53.0+/-96.4 um (p<0.05), respectively. The mean change of CRT 1 month after IVI in each subgroup with VRI abnormalities, apart from the subgroup with retinal wrinkling associated with eccentric ERM, was statistically significantly lower compared to the eyes with normal VRI (p<0.05). Conclusion: VRI abnormalities significantly reduce the effectiveness of intravitreal anti VEGF therapy in eyes with DME. Eyes with noticeable changes of VRI, including ERM involving the macular center, VMA, and VMT have a poorer response to anti-VEGF therapy compared to eyes with normal VRI or eccentric ERM. PMID- 29180845 TI - Clinical outcomes of endoscope-assisted vitrectomy for treatment of rhegmatogenous retinal detachment. AB - Summary: We evaluated the clinical outcomes for ophthalmic endoscope-assisted vitrectomy in consecutive patients with uncomplicated rhegmatogenous retinal detachment (RRD). The primary success rate was 98.4% (125/127) without performing a posterior drainage retinotomy or using perfluorocarbon liquids (PFCL) for subretinal fluid drainage. Purpose: To investigate the clinical outcomes of endoscope-assisted vitrectomy in patients with uncomplicated RRD. Methods: We examined 127 eyes from consecutive patients who underwent repair of RRD by 23- or 25-gauge endoscope-assisted vitrectomy, with a minimum follow-up of 3 months. Eyes with the following criteria were excluded: Giant retinal tears, grade C proliferative vitreoretinopathy, dense vitreous hemorrhage, retinal detachment secondary to other ocular diseases, and prior retinal or vitreous surgery. All cases underwent subretinal fluid drainage, endolaser photocoagulation and fundus inspection were performed under ophthalmic endoscopic observation. Success rate, visual acuity, surgery time and complications were evaluated. Results: Primary and final success rate was 98.4% (125/127) and 100% (127/127), respectively, Surgery time was 59.6+/-26.3 minutes. The best-corrected visual acuity significantly improved from 20/100 to 20/20 (P<0.0001). There were 2 cases (1.6%) of creation of a peripheral drainage retinotomy and 4 cases (3.1%) of using PFCL to suppress movement of the detached retina, but there were no cases of creation of a posterior drainage retinotomy or using PFCL for subretinal fluid drainage. There was 1 case of presumed endophthalmitis after surgery. There were 12 hypotonous cases at postoperative day 1 and one of them needed additional scleral sutures at postoperative day 4 for prolonged hypotony. Conclusion: The present study demonstrated the efficacy of endoscope-assisted vitrectomy for patients with uncomplicated RRD. To perform endoscope-assisted vitrectomy safely, sufficient closure of sclerotomies is necessary at the end of surgery. PMID- 29180846 TI - Different fixation targets affect retinal sensitivity obtained by microperimetry in normal individuals. AB - Purpose: To determine the differences in the retinal sensitivities obtained by microperimetry with a single cross or a circular fixation target in normal individuals. Methods: Thirty-two eyes of 16 healthy volunteers (mean age 28.9+/ 1.4 years, range 24-44 years) were studied. The retinal sensitivity of the central 0 degrees and of the mean central 2 degrees consisting of 8 points were determined independently using the two different fixation targets with Microperimeter 3. The Goldmann III stimulus with a luminance of 1.0 cd/m2 was presented for 200 ms on a white background. Results: The retinal sensitivity of the central 0 degrees was significantly better with the circular target than that with the cross target (P=0.003, right eyes; P=0.001, left eyes). The mean retinal sensitivity in the central 2 degrees was not significantly different between the cross and circular fixation targets. (P=0.07, right eyes; P=0.08, left eyes). Conclusion: These results indicate that the circular fixation target is a better target to use to evaluate the central retinal sensitivity. The difference in the retinal sensitivity is most likely due to the cross fixation target overlapping the test stimulus target. PMID- 29180847 TI - Optic disc segmentation for glaucoma screening system using fundus images. AB - Segmenting the optic disc (OD) is an important and essential step in creating a frame of reference for diagnosing optic nerve head pathologies such as glaucoma. Therefore, a reliable OD segmentation technique is necessary for automatic screening of optic nerve head abnormalities. The main contribution of this paper is in presenting a novel OD segmentation algorithm based on applying a level set method on a localized OD image. To prevent the blood vessels from interfering with the level set process, an inpainting technique was applied. As well an important contribution was to involve the variations in opinions among the ophthalmologists in detecting the disc boundaries and diagnosing the glaucoma. Most of the previous studies were trained and tested based on only one opinion, which can be assumed to be biased for the ophthalmologist. In addition, the accuracy was calculated based on the number of images that coincided with the ophthalmologists' agreed-upon images, and not only on the overlapping images as in previous studies. The ultimate goal of this project is to develop an automated image processing system for glaucoma screening. The disc algorithm is evaluated using a new retinal fundus image dataset called RIGA (retinal images for glaucoma analysis). In the case of low-quality images, a double level set was applied, in which the first level set was considered to be localization for the OD. Five hundred and fifty images are used to test the algorithm accuracy as well as the agreement among the manual markings of six ophthalmologists. The accuracy of the algorithm in marking the optic disc area and centroid was 83.9%, and the best agreement was observed between the results of the algorithm and manual markings in 379 images. PMID- 29180848 TI - Safety and efficacy of the addition of pertuzumab to T-DM1 +/- taxane in patients with HER2-positive, locally advanced or metastatic breast cancer: a pooled analysis. AB - Background: The aim of this review was to systematically evaluate the safety and efficacy of the addition of pertuzumab to trastuzumab emtansine (T-DM1) +/- taxane in patients with human epidermal growth factor receptor 2 (HER2)-positive, locally advanced breast cancer (LABC) or metastatic breast cancer (MBC). Materials and methods: Several databases were searched for relevant clinical trials. The study characteristics, details of adverse events (AEs) and details of treatment efficacy were extracted for analysis. Results: Six studies with 996 patients were included. Common AEs of T-DM1 + pertuzumab +/- taxane included fatigue, diarrhea, nausea, epistaxis, peripheral neuropathy, increased aspartate transaminase (AST), increased alanine transaminase (ALT) and thrombocytopenia. Major grade >=3 AEs of T-DM1 + pertuzumab +/- taxane included thrombocytopenia, neutropenia, fatigue, increased ALT, anemia and peripheral neuropathy. The addition of pertuzumab to T-DM1 +/- taxane led to higher risks of diarrhea (especially grade >=3 diarrhea), rash and vomiting, and decreased risks of thrombocytopenia and grade >=3 increased AST. The relative risks of the addition of pertuzumab to T-DM1 +/- taxane for objective response (1.068, 95% CI 0.945 1.207) and clinical benefit (1.038, 95% CI 0.974-1.106) were not statistically significant. Conclusion: Common AEs should be carefully monitored in HER2 positive LABC or MBC patients treated with T-DM1 + pertuzumab +/- taxane. The addition of pertuzumab to T-DM1 +/- taxane showed noninferior, but not superior, objective response rate and clinical benefit rate. However, more studies are needed to further verify these findings. PMID- 29180849 TI - Adjuvant immunotherapy of dendritic cells and cytokine-induced killer cells is safe and enhances chemotherapy efficacy for multiple myeloma in China: a meta analysis of clinical trials. AB - Objective: The aim of this study was to systematically evaluate the efficacy and safety of the combination of dendritic cells and cytokine-induced killer cells (DC-CIK) adjuvant immunotherapy and chemotherapy in the treatment of multiple myeloma (MM). Methods: Clinical trials were gathered by searching Web of Science, PubMed, Embase, Cochrane Library, Wanfang, and CNKI database. Outcome measurements including therapeutic efficacy, prognosis, immune function, and adverse events were extracted and evaluated. Results: A total of 12 trials including 594 MM patients were involved in this study for statistical analysis. Results indicated that compared to chemotherapy alone, the combination of DC-CIK immunotherapy with chemotherapy significantly improved patients' overall response rate (ORR, odds ratio [OR] =2.77, 95% confidence interval [CI] =1.88-4.10, P<0.00001), disease control rate (DCR, OR =2.90, CI =1.72-4.90, P<0.0001), and life quality (P<0.00001). The combined therapy showed advantages over chemotherapy alone in prognostic indicators including percentage of tumor cells (P=0.04), serum levels of beta2-microglobin (P<0.0001), M protein (P<0.00001), and creatinine (P<0.0001), and 24 h urine light chains (P<0.00001). After combined treatment, CD4+ lymphocyte subsets' percentages, CD4+/CD8+ ratio, and cytokines levels of AgNOR, IFN-gamma, IL-2, and IL-12 were significantly increased (P<0.05), whereas CD8+ and CD4+CD25+ percentages and IL-4, IL-6, IL-10, and TGF-beta levels were obviously decreased (P<0.01), indicating a recovered immune condition. Conclusion: Adjuvant DC-CIK immunotherapy enhances the efficacy of chemotherapy for MM and improves prognosis probably by reconstructing immune function. PMID- 29180850 TI - Role of nebulized glycopyrrolate in the treatment of chronic obstructive pulmonary disease. AB - In the upcoming years, the proportion of elderly patients with chronic obstructive pulmonary disease (COPD) will increase, according to the progressively aging population and the increased efficacy of the pharmacological treatments, especially considering the management of chronic comorbidities. The issue to prescribe an appropriate inhalation therapy to COPD patients with significant handling or coordination difficulties represents a common clinical experience; in the latter case, the choice of an inadequate inhalation device may jeopardize the adherence to the treatment and eventually lead to its ineffectiveness. Treatment options that do not require particular timing for coordination between activation and/or inhalation or require high flow thresholds to be activated should represent the best treatment option for these patients. Nebulized bronchodilators, usually used only in acute conditions such as COPD exacerbations, could fulfill this gap, enabling an adequate drug administration during tidal breathing and without the need for patients' cooperation. However, so far, only short-acting muscarinic antagonists have been available for nebulization. Recently, a nebulized formulation of the inhaled long-acting muscarinic antagonist glycopyrrolate, delivered by means of a novel proprietary vibrating mesh nebulizer closed system (SUN-101/eFlow(r)), has progressed to Phase III trials and is currently in late-stage development as an option for maintenance treatment in COPD. The present critical review describes the current knowledge about the novel nebulizer technology, the efficacy, safety, and critical role of nebulized glycopyrrolate in patients with COPD. To this end, PubMed, ClinicalTrials.gov, Embase, and Cochrane Library have been searched for relevant papers. According to the available results, the efficacy and tolerability profile of nebulized glycopyrrolate may represent a valuable and dynamic treatment option for the chronic pharmacological management of patients with COPD. PMID- 29180851 TI - Differences of statin activity in 2D and 3D pancreatic cancer cell cultures. AB - Purpose: To evaluate the anticancer activity of lovastatin (LOVA), mevastatin (MEVA), pitavastatin (PITA), and simvastatin (SIMVA) in 2D and 3D models of three human pancreatic cancer cell lines (BxPC-3, MIA PaCa-2, and PANC-1). Methods: The effect of statins on cell viability was estimated by 3-(4,5-dimethylthiazol-2-yl) 2,5-diphenyltetrazolium bromide test. The activity of statins in 3D pancreatic cancer cell cultures was examined by measuring the size change of spheroids. The type of cell death was identified by cell staining with Hoechst 33342 and propidium iodide. The activity of statins on the clonogenicity of cancer cells was tested by evaluating the effect on the colony-forming ability of cells. Results: The rank order of the activity of tested statins on cell viability was as follows: PITA > SIMVA > LOVA > MEVA. Among the tested statins, PITA had the greatest effect on cell viability (half maximal effective concentration values after 72 h on BxPC-3, MIA PaCa-2, and PANC-1 cells were 1.4+/-0.4 MUM, 1.0+/-0.2 MUM, and 1.0+/-0.5 MUM, respectively). PITA also showed the strongest effect on tumor spheroid growth. Statins suppressed the colony formation of cancer cells. PITA demonstrated the greatest reduction in colony size and number. Apoptosis and necrosis assay results showed that at lower concentrations statins mostly induced cell death through apoptosis, whereas higher concentrations of compounds activated also necrotic processes. Conclusion: Statins, especially PITA, demonstrate an anticancer activity against pancreatic cancer cell lines BxPC-3, MIA PaCa-2, and PANC-1 in both 2D and 3D models. PMID- 29180852 TI - In silico-based identification of human alpha-enolase inhibitors to block cancer cell growth metabolically. AB - Unlimited growth of cancer cells requires an extensive nutrient supply. To meet this demand, cancer cells drastically upregulate glucose uptake and metabolism compared to normal cells. This difference has made the blocking of glycolysis a fascinating strategy to treat this malignant disease. alpha-enolase is not only one of the most upregulated glycolytic enzymes in cancer cells, but also associates with many cellular processes or conditions important to cancer cell survival, such as cell migration, invasion, and hypoxia. Targeting alpha-enolase could simultaneously disturb cancer cells in multiple ways and, therefore, is a good target for anticancer drug development. In the current study, more than 22 million chemical structures meeting the criteria of Lipinski's rule of five from the ZINC database were docked to alpha-enolase by virtual screening. Twenty-four chemical structures with docking scores better than that of the enolase substrate, 2-phosphoglycerate, were further screened by the absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties prediction. Four of them were classified as non-mutagenic, non-carcinogenic, and capable of oral administration where they showed steady interactions to alpha-enolase that were comparable, even superior, to the currently available inhibitors in molecular dynamics (MD) simulation. These compounds may be considered promising leads for further development of the alpha-enolase inhibitors and could help fight cancer metabolically. PMID- 29180853 TI - New insights into frequency and contents of fear of cancer progression/recurrence (FOP/FCR) in outpatients with colorectal carcinoma (CRC) receiving oral capecitabine: a pilot study at a comprehensive cancer center. AB - Background: Fear of cancer progression/recurrence (FOP/FCR) is considered one of the most prevalent sources of distress in cancer survivors and associated with lower quality of life and functional impairment. Detailed measures of FOP/FCR are needed because little is known about the knowledge of FOP/FCR, its associations with the patient-doctor relationship, and the rate of adequate therapy. Colorectal cancer (CRC) is one of the most prevalent cancer entities, and oral capecitabine is widely prescribed as treatment. Therefore, we initiated a pilot study to expand the literature on FOP/FCR in CRC outpatients receiving capecitabine and to generate hypotheses for future investigations. Methods: This study included 58 patients treated at a comprehensive cancer center. FOP/FCR was assessed with the Fear of Progression Questionnaire (FOP-Q-SF). Satisfaction with the relationships with doctors was assessed with the Patient-Doctor Relationship Questionnaire-9 (PRDQ-9). Levels of side effects were rated by the patients on a visual analog scale. Clinical data were extracted from the charts. Results: A total of 19 out of 58 patients (36%) suffered from FOP/FCR according to our assessment. Levels of FOP/FCR seemed to be mostly moderate to high. Only four out of the 19 distressed patients (21%) were treated accordingly. Typical side effects of oncological treatment were associated with higher FOP/FCR. Satisfaction with doctor-patient relationships was not associated with FOP/FCR. Regarding single items of FOP/FCR, three out of the five most prevalent fears were associated with close relatives. Discussion: FOP/FCR occurred frequently in more than one in three patients, but was mostly untreated in this sample of consecutive outpatients with CRC receiving oral capecitabine. In detail, most fears were related to family and friends. In addition to an unmet need of patients, our data indicate sources of distress not considered thus far. If replicated in larger studies, results may help to inform intervention development and improve patient care. PMID- 29180854 TI - Antimicrobial characterization of silver nanoparticle-coated surfaces by "touch test" method. AB - Bacterial infections, especially by antimicrobial resistant (AMR) bacteria, are an increasing problem worldwide. AMR is especially a problem with health care associated infections due to bacteria in hospital environments being easily transferred from patient to patient and from patient to environment, and thus, solutions to prevent bacterial transmission are needed. Hand washing is an effective tool for preventing bacterial infections, but other approaches such as nanoparticle-coated surfaces are also needed. In the current study, direct and indirect liquid flame spray (LFS) method was used to produce silver nanoparticle coated surfaces. The antimicrobial properties of these nanoparticle surfaces were evaluated with the "touch test" method against Escherichia coli and Staphylococcus aureus. It was shown in this study that in glass samples one silver nanoparticle-coating cycle can inhibit E. coli growth, whereas at least two coating cycles were needed to inhibit S. aureus growth. Silver nanoparticle coated polyethylene (PE) and PE terephthalate samples did not inhibit bacterial growth as effectively as glass samples: three nanoparticle-coating cycles were needed to inhibit E. coli growth, and more than 30 coating cycles were needed until S. aureus growth was inhibited. To conclude, with the LFS method, it is possible to produce nanostructured large-area antibacterial surfaces which show antibacterial effect against clinically relevant pathogens. Results indicate that the use of silver nanoparticle surfaces in hospital environments could prevent health care-associated infections in vivo. PMID- 29180855 TI - Aural stimulation with capsaicin ointment improved swallowing function in elderly patients with dysphagia: a randomized, placebo-controlled, double-blind, comparative study. AB - Objective: The aim of this study was to assess whether aural stimulation with ointment containing capsaicin improves swallowing function in elderly patients with dysphagia. Study design: A randomized, placebo-controlled, double-blind, comparative study. Settings: Secondary hospital. Patients and methods: Twenty elderly dysphagic patients with a history of cerebrovascular disorder or Parkinson's disease were randomly divided into two groups: 10 receiving aural stimulation with 0.025% capsaicin ointment and 10 stimulated with placebo. The ointments were applied to the external auditory canal with a cotton swab. Then, swallowing of a bolus of blue-dyed water was recorded using transnasal videoendoscopy, and the swallowing function was evaluated according to both endoscopic swallowing scoring and Sensory-Motor-Reflex-Clearance (SMRC) scale. Results: The sum of endoscopic swallowing scores was significantly decreased 30 and 60 min after a single administration in patients treated with capsaicin, but not with placebo. Reflex score, but not Sensory, Motion and Clearance scores, of the SMRC scale was significantly increased 5, 30 and 60 min after single administration in patients treated with capsaicin, but not with placebo. No patient showed signs of adverse effects. Conclusion: As capsaicin is an agonist of the transient receptor potential vanilloid 1 (TRPV1), these findings suggest that improvement of the swallowing function, especially glottal closure and cough reflexes, in elderly dysphagic patients was due to TRPV1-mediated aural stimulation of vagal Arnold's nerve with capsaicin, but not with a nonspecific mechanical stimulation with a cotton swab. PMID- 29180856 TI - Effects of comprehensive geriatric assessment on physical fitness in an acute medical setting for frail elderly patients. AB - Introduction: Frail elderly people often use emergency care. During hospitalization, physical decline is common, implying an increased risk of adverse health outcomes. Comprehensive Geriatric Assessment (CGA) has been shown to be beneficial for these patients in hospital care. However, there is very limited evidence about the effects on physical fitness. The aim was to compare effects on physical fitness in the acute care of frail elderly patients at a CGA unit versus conventional care, 3 months after discharge. Patients and methods: A clinical, prospective, controlled trial with two parallel groups was conducted. Patients aged >=75 years, assessed as frail and in need of inpatient care, were assigned to a CGA unit or conventional care. Measurements of physical fitness, including handgrip strength (HS), timed up-and-go (TUG), and the 6-minute walk test (6-MWT) were made twice, at the hospital index care period and at the 3 month follow-up. Data were analyzed as the mean change from index to the 3-month follow-up, and dichotomized as decline versus stability/improvement in physical fitness. Results: In all, 408 participants, aged 85.7+/-5.4 years, were included. The intervention group improved significantly in all components of physical fitness. The controls improved in TUG and declined in HS and 6-MWT. When the changes were dichotomized the intervention group declined to a lesser extent; HS p<0.001, 6-MWT p<0.001, TUG p<0.003. The regression analysis showed the following odds ratios (ORs) for how these outcomes were influenced by the intervention; HS OR 4.4 (confidence interval [CI] 95% 2.2-9.1), 6-MWT OR 13.9 (CI 95% 4.2-46.2), and TUG OR 2.5 (CI 95% 1.1-5.4). Conclusion: This study indicates that the acute care of frail elderly patients at a CGA unit is superior to conventional care in terms of preserving physical fitness at 3 months follow-up. CGA management may positively influence outcomes of great importance for these patients, such as mobility, strength, and endurance. PMID- 29180858 TI - The impact of age and preoperative health-related quality of life on patient reported improvements after total hip arthroplasty. AB - Background: Total hip arthroplasty (THA) is a common surgical procedure and approximately 9,500 of these surgeries are performed annually in Denmark. The operation is considered effective and successful with respect to complications, mortality, and implant survival. However, using patient-reported outcome measures, up to 10% of patients are not satisfied with the outcome of their operation. To address this, it is important to find out why some patients experience impaired outcomes after THA. The purpose of this study was to investigate the impact of age and preoperative health-related quality of life (HRQoL) on improvements in HRQoL after THA. Methods: A cohort study was conducted with follow-up at 3 and 12 months. Patients were included from September 2008 to December 2013. We analyzed 1,283 THA cases. HRQoL was measured using the EuroQol 5 Domain. Analyses were carried out with multiple linear regression and adjusted for relevant variables available in the data set. Results: A significant positive association was found between age and HRQoL outcomes for patients who underwent THA at both 3 (beta [regression coefficient] 0.0026, confidence interval [CI] 0.0013; 0.0039, p<0.001) and 12 (beta 0.0020 CI 0.0008; 0.0032, p=0.001) months of follow-up. A clinically relevant change was achieved with an increase in age of 12-15 years. A significant negative association was found between preoperative HRQoL and HRQoL outcomes at both 3 (beta -0.841 CI -0.886; -0.795, p<0.001) and 12 (beta -0.804 CI -0.844; -0.764, p<0.001) months of follow-up. Conclusion: Contrary to our expectations, older patients had more improvements in HRQoL outcomes after THA. A high preoperative HRQoL seems to inhibit improvements in HRQoLs after THA. PMID- 29180857 TI - Association between apolipoprotein E gene polymorphism and mild cognitive impairment: a meta-analysis. AB - A number of published case-control studies reported that the apolipoprotein E (ApoE) gene polymorphism was associated with the mild cognitive impairment (MCI). However, previous reports still remain conflicting. To estimate the association between ApoE polymorphism and MCI susceptibility, we searched the electronic databases including PubMed, Wanfang, CNKI (China National Knowledge Infrastructure), VIP, and EMBASE to retrieve all available studies. A total of 18 studies with 2,004 cases and 3,705 controls were included in this meta-analysis. The pooled analysis based on selected studies showed that statistically significant risk association was found between ApoE gene polymorphism and MCI in overall population (epsilon4 vs epsilon3: odds ratio [OR] =2.38, 95% confidence interval [CI]: 2.11-2.68; epsilon4/epsilon4 vs epsilon3/epsilon3: OR =4.45, 95% CI: 3.06-6.48; epsilon2/epsilon4 vs epsilon3/epsilon3: OR =2.57, 95% CI: 1.77 3.73; epsilon3/epsilon4 vs epsilon3/epsilon3: OR =2.31, 95% CI: 1.99-2.69). However, no significant association was detected in two genetic models: epsilon2 versus epsilon3 (OR =0.90, 95% CI: 0.77-1.05) and epsilon2/epsilon2 versus epsilon3/epsilon3 (OR =0.91, 95% CI: 0.50-1.65). Furthermore, ApoE epsilon2/epsilon3 genotype provided a slight protection for MCI in overall population (epsilon2/epsilon3 vs epsilon3/epsilon3: OR =0.80, 95% CI: 0.66-0.97). In the stratified analysis based on ethnicity, similar results were also observed in Chinese population (significant risk: epsilon4 vs epsilon3: OR =2.52, 95% CI: 2.19-2.90; epsilon4/epsilon4 vs epsilon3/epsilon3: OR =5.45, 95% CI: 3.41-8.70; epsilon2/epsilon4 vs epsilon3/epsilon3: OR =2.59, 95% CI: 1.74-3.86; epsilon3/epsilon4 vs epsilon3/epsilon3: OR =2.34, 95% CI: 1.97-2.79; slight protection: epsilon2/epsilon3 vs epsilon3/epsilon3: OR =0.79, 95% CI: 0.64-0.98; no association: epsilon2 vs epsilon3: OR =0.92, 95% CI: 0.78-1.09; and epsilon2/epsilon2 vs epsilon3/epsilon3: OR =1.04, 95% CI: 0.55-1.99). In summary, this meta-analysis of 5,709 subjects suggested that ApoE epsilon4 allele was associated with an increased risk of MCI. In addition, ApoE epsilon2/epsilon3 genotype provided a slight protection for MCI. PMID- 29180859 TI - Hyponatremia in the elderly: challenges and solutions. AB - Decreased serum sodium concentration is a rather frequent electrolyte disorder in the elderly population because of the presence of factors contributing to increased antidiuretic hormone, the frequent prescription of drugs associated with hyponatremia and also because of other mechanisms such as the "tea and toast" syndrome. The aim of this review is to present certain challenges in the evaluation and treatment of hyponatremia in the elderly population and provide practical solutions. Hyponatremia in elderly subjects is mainly caused by drugs (more frequently thiazides and antidepressants), the syndrome of inappropriate antidiuretic hormone secretion (SIAD) or endocrinopathies; however, hyponatremia is multifactorial in a significant proportion of patients. Special attention is needed in the elderly population to exclude endocrinopathies as a cause of hyponatremia before establishing the diagnosis of SIAD, which then requires a stepped diagnostic approach to reveal its underlying cause. The treatment of hyponatremia depends on the type of hyponatremia. Special attention is also needed to correct serum sodium levels at the appropriate rate, especially in chronic hyponatremia, in order to avoid the osmotic demyelination syndrome. In conclusion, both the evaluation and the treatment of hyponatremia pose many challenges in the elderly population. PMID- 29180860 TI - Different impacts of respiratory symptoms and comorbidities on COPD-specific health-related quality of life by COPD severity. AB - Background: Patients with chronic obstructive pulmonary disease (COPD) often have poor health-related quality of life (HRQoL) that is disproportionate to their degree of airflow limitation. This study evaluated the association between St George's Respiratory Questionnaire for COPD (SGRQ-C) score and forced expiratory volume in one second and investigated the factors responsible for high SGRQ-C score according to severity of airflow limitation. Methods: Data from 1,264 COPD patients were obtained from the Korean COPD Subgroup Study (KOCOSS) cohort. Patients were categorized into two groups according to severity of airflow limitation: mild-to-moderate and severe-to-very severe COPD groups. We evaluated the clinical factors associated with high SGRQ-C score (>=25) in each COPD patient group. Results: Of the 1,264 COPD patients, 902 (71.4%) had mild-to moderate airflow limitation and 362 (28.6%) had severe-to-very severe airflow limitation. Of the mild-to-moderate COPD patients, 59.2% (534/902) had high SGRQ C score, while 80.4% (291/362) of the severe-to-very severe COPD patients had high SGRQ-C score. The association between SGRQ-C score and post-bronchodilator forced expiratory volume in one second (% predicted) was very weak in the mild-to moderate COPD patients (r=-0.103, p=0.002) and weak in the severe-to-very severe COPD patients (r=-0.219, p<0.001). Multiple logistic regression analysis revealed that age, being an ex- or current smoker, lower level of education, cough, dyspnea, and number of comorbidities with congestive heart failure, hyperlipidemia, and depression were significantly associated with high SGRQ-C score in mild-to-moderate COPD patients. In comparison, being an ex-smoker and having respiratory symptoms including sputum and dyspnea were significant factors associated with high SGRQ-C score in severe-to-very severe COPD patients. Conclusions: In addition to the respiratory symptoms of dyspnea and cough, high SGRQ-C score was associated with extra-pulmonary comorbidities in mild-to moderate COPD patients. However, only respiratory symptoms such as sputum and dyspnea were significantly associated with high SGRQ-C score in severe-to-very severe COPD patients. This indicates the need for an improved management strategy for relieving respiratory symptoms in COPD patients with poor HRQoL. In addition, attention should be paid to extra-pulmonary comorbidities, especially in mild-to moderate COPD patients with poor HRQoL. PMID- 29180861 TI - Healthy lifestyle behaviors among individuals with chronic obstructive pulmonary disease in urban and rural communities in China: a large community-based epidemiological study. AB - Background: Lifestyle modification is one of the most cost-effective strategies in self-management and secondary prevention of chronic obstructive pulmonary disease (COPD). However, the prevalence of healthy lifestyle behaviors in COPD patients in China remains unclear. The objective of this study was to examine the rates of healthy lifestyle behaviors including smoking cessation, regular exercise, and healthy diet in community population with COPD in China. Methods: We recruited 46,285 individuals aged 35-70 years from 115 urban and rural communities in 12 provinces of China from 2005 to 2009. We recorded the smoking status, physical activity intensity, and quality of diet for all spirometry diagnosed COPD patients by standardized questionnaires. Results: Among 3,690 individuals with COPD, 18.2% (95% confidence interval [CI], 13.0-24.9) quitted smoking, 27.1% (95% CI, 24.7-29.7) exercised often, and 34.8% (95% CI, 31.8-38.0) ate high-quality diet. More than half of the individuals followed one or less key healthy lifestyle, and only 8.4% (95% CI, 7.0-10.0) followed all of the three healthy behaviors. Urban residents had significant higher rates of smoking cessation (23.5% [95% CI, 17.3-31.1] vs 14.4% [95% CI, 9.9-20.5], p=0.0008), regular exercise (45.6% [95% CI, 42.4-48.8] vs 14.0% [95% CI, 12.1-16.2], p<0.0001), and healthy diet (38.5% [95% CI, 35.5-41.6] vs 32.2% [95% CI, 29.2 35.4], p=0.0013) than rural residents. Age, sex, education level, body mass index, respiratory symptoms, and family income were associated with healthy living, and the strength of associations varied between urban and rural areas. Conclusion: There is a large gap between the anticipated rate and the real participation in healthy lifestyle behaviors in Chinese adults with COPD, especially in rural communities. Simple and effective strategies are warranted to improve patients' lifestyle in China. PMID- 29180862 TI - Smoking cessation affects the natural history of COPD. AB - Background: Cigarette smoking is the most commonly encountered and readily identifiable risk factor for COPD. However, it is not clear which quantitative factors related to smoking influence the prognosis of COPD patients. Methods: A total of 204 patients with a long-term history of smoking were enrolled into this study and followed up for 5 years. Patients were divided into "death" or "survival" groups based on follow-up results and "quitting-smoking" or "continuing-smoking" groups based on whether they gave up smoking. Results: Patients in the death group had a longer smoking time, lower prevalence of quitting smoking, later onset of COPD symptoms, older age at quitting smoking, lower forced expiratory volume in one second (FEV1) % predicted, and lower ratio of FEV1/forced vital capacity. Age, age at quitting smoking, and FEV1% predicted were independently associated with mortality from COPD. Compared to the continuing-smoking group, the quitting-smoking group had a lower mortality rate, longer course of COPD, earlier onset of COPD symptoms, and lower residual volume percent predicted. During the 5-year follow-up, 113 deaths were recorded (quitting-smoking group: n=92; 40 deaths; continuing-smoking group: n=112; 73 deaths). The mortality risk remained significantly higher in the continuing smoking group than the quitting-smoking group (log-rank test, 13.59; P=0.0002). Conclusion: Smoking time may be related to the mortality rate from COPD. Smoking cessation has the greatest capacity to influence the natural history of COPD. PMID- 29180863 TI - Paclitaxel and quercetin nanoparticles co-loaded in microspheres to prolong retention time for pulmonary drug delivery. AB - High drug resistance, poor water solubility, short half-life, and low local drug concentration are obstacles for successful delivery of chemotherapeutic drugs for lung cancer. A new method involving the use of nanoparticles (NPs) for pulmonary delivery is proposed. However, use of NPs is limited by the particle size range for pulmonary drug delivery considering that NPs cannot be deposited directly into the lungs. NPs polymerized into microspheres (polymeric microspheres, PMs) will result in suitable particle sizes and retain the advantages of nanodrugs after redispersion when applied in pulmonary delivery. We report the development of novel NPs in the form of PMs loaded with paclitaxel (PTX) and quercetin (QUE) double drugs based on the synthesis of oleic acid-conjugated chitosan (OA-CTS) for pulmonary delivery. This approach is aimed toward prolonging PTX retention time in the presence of QUE and bypassing P-glycoprotein drug efflux pumps. NPs loaded with PTX or QUE were prepared with 11% substitution degree using OA-CTS as the carrier by ionic cross-linking method, which NPs loaded with PTX or QUE were used in the preparation of PMs by spray-drying. The diameters of the PMs ranged from 1 to 5 MUm which had uniform size range. Scanning electron microscopy showed that PMs were polymers formed by a large number of NPs and readily redispersed (after redispersion, size of NPs ranged between 250 and 350 nm) in water within 1 h. PMs displayed slow-release characteristics at pH 4.5 and 7.4. The in vivo pharmacokinetic and biodistribution studies suggested that PMs exhibit prolonged circulation time and a markedly high accumulation in the lung. The obtained results indicate that PMs can serve as a promising pulmonary delivery system for combined pharmacotherapy using hydrophobic anticancer drugs. PMID- 29180864 TI - A nanoliposome-based photoactivable drug delivery system for enhanced cancer therapy and overcoming treatment resistance. AB - Recently, stimuli-responsive drug delivery systems (DDSs) with high spatial/temporal resolution bring many benefits to cancer treatment. However, cancer cells always develop ways to resist and evade treatment, ultimately limit the treatment efficacy of the DDSs. Here, we introduce photo-activated nanoliposomes (PNLs) that impart light-induced cytotoxicity and reversal of drug resistance in synchrony with a photoinitiated and rapid release of antitumor drug. The PNLs consist of a nanoliposome doped with a photosensitizer (hematoporphyrin monomethyl ether [HMME]) in the lipid bilayer and an antitumor drug doxorubicin (DOX) encapsulated inside. PNLs have several distinctive capabilities: 1) carrying high loadings of DOX and HMME and releasing the payloads in a photo-cleavage manner with high spatial/temporal resolution at the site of actions via photocatalysis; 2) reducing drug efflux in MCF-7/multidrug resistance cells via decreasing the level of P-glycoprotein induced by photodynamic therapy (PDT); 3) accumulating in tumor site taking advantage of the enhanced permeability and retention effect; and 4) combining effective chemotherapy and PDT to exert much enhanced anticancer effect and achieving significant tumor regression in a drug-resistant tumor model with little side effects.

AB - Our previous study revealed that mesoporous Ca-Si-based materials exhibited excellent osteoconduction because dissolved ions could form a layer of hydroxycarbonate apatite on the surface of the materials. However, the biological mechanisms underlying bone regeneration were largely unknown. The main aim of this study was to evaluate the osteogenic ability of large-pore mesoporous Ca-Si based bioceramics (LPMSCs) by alkaline phosphatase assay, real-time PCR analysis, von Kossa, and alizarin red assay. Compared with large-pore mesoporous silica (LPMS), LPMSCs had a better effect on the osteogenic differentiation of dental pulp cells. LPMSC-2 and LPMSC-3 with higher calcium possessed better osteogenic abilities than LPMSC-1, which may be related to the calcium-sensing receptor pathway. Furthermore, the loading capacity for recombinant human platelet-derived growth factor-BB was satisfactory in LPMSCs. In vivo, the areas of new bone formation in the calvarial defect repair were increased in the LPMSC-2 and LPMSC 3 groups compared with the LPMSC-1 and LPMS groups. We concluded that LPMSC-2 and LPMSC-3 possessed both excellent osteogenic abilities and satisfactory loading capacities, which may be attributed to their moderate Ca/Si molar ratio. Therefore, LPMSCs with moderate Ca/Si molar ratio might be potential alterative grafts for craniomaxillofacial bone regeneration.

AB - Purpose: This study assessed early-onset psychiatric disorders and factors related to these disorders in a group of refugee children after immigration due to war. Materials and methods: This study was conducted between January 2016 and June 2016. Clinical interviews were conducted with 89 children and their families, and were performed by native speakers of Arabic and Persian who had been primarily educated in these languages and were living in Turkey. A strengths and difficulties questionnaire (SDQ) that had Arabic and Persian validity and reliability was applied to both children and their families. Independent variables for cases with and without a psychiatric disorder were analyzed using the chi2 test for categorical variables, Student's t-test for those that were normally distributed, and Mann-Whitney U-test for data that were not normally distributed. Data that showed significant differences between groups who had a psychiatric disorder and on common effects in emerging psychiatric disorders were analyzed through binary logistic regression analysis. Results: A total of 89 children and adolescents were interviewed within the scope of the study. The mean age of cases was 9.96+/-3.98 years, and 56.2% (n=50) were girls, while 43.8% (n=39) were boys. Among these children, 47 (52.8%) had come from Syria, 27 (30.3%) from Iraq, 14 (15.7%) from Afghanistan, and 1 (1.1%) from Iran. A psychiatric disorder was found in 44 (49.4%) of the children. A total of 26 children were diagnosed with anxiety disorders, 12 with depressive disorders, 8 with trauma and related disorders, 5 with elimination disorders, 4 with attention deficit/hyperactivity disorder, and 3 with intellectual disabilities. It was determined that seeing a dead or injured person during war/emigration and the father's unemployment increased the risk of psychopathology. The OR was 7.077 (95% CI 1.722-29.087) for having seen a dead or injured individual and 4.51 (95% GA 1.668-12.199) for father's employment status. Conclusion: Within the context of war and emigration, these children try to cope with the negative circumstances they experience prior to migration, as well as the despair they see their parents experience. PMID- 29180866 TI - Biotransport kinetics and intratumoral biodistribution of malonodiserinolamide derivatized [60]fullerene in a murine model of breast adenocarcinoma. AB - [60]Fullerene is a highly versatile nanoparticle (NP) platform for drug delivery to sites of pathology owing to its small size and both ease and versatility of chemical functionalization, facilitating multisite drug conjugation, drug targeting, and modulation of its physicochemical properties. The prominent and well-characterized role of the enhanced permeation and retention (EPR) effect in facilitating NP delivery to tumors motivated us to explore vascular transport kinetics of a water-soluble [60]fullerene derivatives using intravital microscopy in an immune competent murine model of breast adenocarcinoma. Herein, we present a novel local and global image analysis of vascular transport kinetics at the level of individual tumor blood vessels on the micron scale and across whole images, respectively. Similar to larger nanomaterials, [60]fullerenes displayed rapid extravasation from tumor vasculature, distinct from that in normal microvasculature. Temporal heterogeneity in fullerene delivery to tumors was observed, demonstrating the issue of nonuniform delivery beyond spatial dimensions. Trends in local region analysis of fullerene biokinetics by fluorescence quantification were in agreement with global image analysis. Further analysis of intratumoral vascular clearance rates suggested a possible enhanced penetration and retention effect of the fullerene compared to a 70 kDa vascular tracer. Overall, this study demonstrates the feasibility of tracking and quantifying the delivery kinetics and intratumoral biodistribution of fullerene based drug delivery platforms, consistent with the EPR effect on short timescales and passive transport to tumors. PMID- 29180868 TI - The efficacy of antipsychotics for prolonged delirium with renal dysfunction. AB - Aim: Delirium is commonly encountered in daily clinical practice. To identify predictors influencing outcomes, we retrospectively examined the characteristics of inpatients with delirium who required psychiatric medication during hospitalization. Methods: We extracted all new inpatients (n=523) consulted for psychiatric symptoms at Fukushima Medical University Hospital between October 2011 and September 2013. We selected 203 inpatients with delirium diagnosed by psychiatrists. We analyzed data from 177 inpatients with delirium who received psychiatric medication. We defined an "early improvement group" in which delirium resolved in <=3 days after starting psychiatric medication, and a "prolonged group" with delirium lasting for >3 days. Among the 83 inpatients with renal dysfunction (estimated glomerular filtration rate <60 mL/min/1.73 m2), we defined an "early improvement group with renal dysfunction" in which delirium resolved in <=3 days after starting psychiatric medication and a "prolonged group with renal dysfunction" with delirium lasting for >3 days. We then examined differences between groups for different categorical variables. Results: Dose of antipsychotic medication at end point was significantly lower in the prolonged group with renal dysfunction than in the early improvement group with renal dysfunction. Conclusion: The results suggest that maintaining a sufficient dose of antipsychotics from an early stage may prevent prolongation of delirium even in inpatients with renal dysfunction. PMID- 29180869 TI - ECMO as an effective rescue therapeutic for fulminant myocarditis complicated with refractory cardiac arrest. AB - Fulminant myocarditis (FM) is a life-threatening disease in children. With a rapid, progressive course of deterioration, it causes refractory cardiorespiratory failure even with optimal clinical intervention. We present the case of a 9-year-old girl with FM complicated by cardiogenic shock, malignant arrhythmia, and refractory cardiac arrest. She received effective cardiopulmonary resuscitation, therapeutic hypothermia, and other supportive treatments. However, the patient rapidly worsened into pulseless ventricular tachycardia and refractory cardiac arrest. Therefore, we performed extracorporeal membrane oxygenation (ECMO) to establish spontaneous circulation after the failure of standard resuscitation measures. The girl recovered with intact cardiac and neurocognitive functions after continued ECMO treatment for 221 hours. Therefore, ECMO is an effective rescue therapeutics for FM, especially when complicated with refractory cardiac arrest. PMID- 29180870 TI - The effect of antiviral therapy on patients with hepatitis B virus-related hepatocellular carcinoma after curative resection: a systematic review and meta analysis. AB - Background and aim: Studies suggest that antiviral therapy performed after curative resection improves the postoperative prognosis of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC), but the evidence has been contradictory. The aim of this meta-analysis was to assess the effect of antiviral therapy with nucleoside analogs (NAs) after curative resection on the long-term postoperative survival of patients with HBV-related HCC. Materials and methods: MEDLINE, PubMed, Embase, and Cochrane Library were systematically searched up to August 2017 with no limits. Outcome measures were the primary parameter of overall survival (OS) after radical resection of HBV-related HCC and the secondary parameter of postoperative recurrence-free survival (RFS). Results: A total of 9,009 patients (2,546 of whom received antiviral therapy and 6,463 received no treatment) were included. The pooled analysis revealed that antiviral therapy was associated with significantly improved OS (hazard ratio [HR]: 0.58; 95% confidence interval [CI]: 0.51-0.67; P<0.00001) and RFS (HR: 0.68; 95% CI: 0.63-0.74; P<0.00001). Moderate heterogeneity among studies for both OS and RFS was observed, which disappeared or decreased after pooling studies using one type of NA as antiviral drug. In the subgroup analysis, anti-viral therapy significantly prolonged both OS (HR: 0.69; 95% CI: 0.52-0.92; P=0.01) and RFS (HR: 0.58; 95% CI: 0.49-0.70; P<0.00001) in patients with high baseline HBV DNA level (>=20,000 IU/mL) with no heterogeneity, but not in patients with low baseline HBV DNA level (<20,000 IU/mL). Conclusion: Antiviral therapy with NAs confers significant survival benefits in patients with HBV-related HCC after curative resection, especially in patients with high baseline HBV DNA level (>=20,000 IU/mL). PMID- 29180871 TI - LncRNA NEAT1 contributes to paclitaxel resistance of ovarian cancer cells by regulating ZEB1 expression via miR-194. AB - Background: Chemoresistance is one of the major obstacles for cancer therapy in the clinic. Nuclear paraspeckle assembly transcript 1 (NEAT1) has been reported as an oncogene in most malignancies such as lung cancer, esophageal cancer, and gastric cancer. This study is designed to investigate the function of NEAT1 in paclitaxel (PTX) resistance of ovarian cancer and its potential molecular mechanism. Patients and methods: The expressions of NEAT1 and miR-194 in ovarian cancer tissues and cells were estimated by quantitative real-time polymerase chain reaction (qRT-PCR). MTT, flow cytometry, and Western blot assays were used to assess the effect of NEAT1 on PTX resistance in PTX-resistant ovarian cancer cells. Luciferase reporter assay was applied to examine the association between NEAT1, zinc finger E-box-binding homeobox 1 (ZEB1) and miR-194. Xenograft tumor model was established to confirm the biological role of NEAT1 in PTX resistance of ovarian cancer in vivo. Results: NEAT1 was upregulated, and miR-194 was downregulated in PTX-resistant ovarian cancer tissues and cells. Functionally, NEAT1 knockdown enhanced cell sensitivity to PTX via promoting PTX-induced apoptosis in vitro. NEAT1 was identified as a molecular sponge of miR-194 to upregulate ZEB1 expression. Mechanistically, NEAT1-knockdown-induced PTX sensitivity was mediated by miR-194/ZEB1 axis. Moreover, NEAT1 knockdown improved PTX sensitivity of ovarian cancer in vivo. Conclusion: NEAT1 contributed to PTX resistance of ovarian cancer cells at least partly through upregulating ZEB1 expression by sponging miR-194, elucidating a novel regulatory pathway of chemoresistance in PTX-resistant ovarian cancer cells and providing a possible long noncoding RNA (lncRNA)-targeted therapy for ovarian cancer. PMID- 29180872 TI - Therapeutic efficacy and safety of combined BRAF and MEK inhibition in patients with malignant melanoma: a meta-analysis. AB - Background: Recent clinical studies have shown that initial therapy with combined BRAF and mitogen-activated extracellular signal-regulated kinase (MEK) inhibition is more effective in metastatic melanoma than single-agent BRAF inhibitors. However, the response rates with single-agent BRAF are low. Thus, the objective of this study was to conduct a meta-analysis of randomized controlled trials to compare the efficacy and adverse events risk between mono-therapy and combination therapy. Materials and methods: Searches were made in PubMed and EMBASE electronic databases and conference abstracts published by the American Society of Clinical Oncology from 2000 to 2017. Outcomes included overall response, progression-free survival, and overall survival, as well as the incidence rate of adverse events. Results: Eight trials comprising 2,664 patients were included in the meta-analysis. Patients with combined therapies showed superior results compared to those with BRAF inhibitors alone for the following: overall response rate (combined relative risk [RR] =1.34, 95% confidence interval [95% CI]: 1.24 1.45, P<0.00001), progression-free survival (combined hazards ratio [HR] =0.58, 95% CI: 0.52-0.64, P<0.00001), and overall survival rate (combined HR =0.70, 95% CI: 0.62-0.80, P<0.00001). Patients with combination therapies had higher incidence of adverse events including pyrexia (combined RR =2.00, 95% CI: 1.40 2.84), nausea (combined RR =1.41, 95% CI: 1.03-1.94), diarrhea (combined RR =1.50, 95% CI: 1.08-2.06), and vomiting (combined RR =1.87, 95% CI: 01.52-2.31) compared to those with BRAF inhibitors alone. Conclusion: These data suggested that the combined BRAF and MEK inhibition was associated with a significant improvement in overall response, progression-free survival, and overall survival, but increased the incidence of adverse events among the patients with BRAF V600 mutated metastatic melanoma. Further large-scale, high-quality, placebo controlled, double-blind trials are needed to confirm this conclusion. PMID- 29180873 TI - In vitro study on anti-cancer properties of genistein in tongue cancer. AB - Purpose: Tongue cancer is an extremely aggressive disease and is characterized by a poor prognosis. It is a complex disease to treat and current therapies have produced mediocre results with many side effects. Some facts suggest that natural essences can support traditional cancer therapy by carrying out a synergistic function with chemotherapy. Therefore, we evaluated the antitumor effects of genistein on tongue carcinoma cells. Methods: Genistein 20, 50 and 100 uM were used for 24, 48 and 72 hours on 3 tongue carcinoma cell lines. xCELLigence system was used to evaluate the effects on cell adhesion, proliferation and to calculate IC50 values. Both MTT assay and Trypan blue assay were used to evaluate alterations in cell viability, scratch assay for cell migration and Western blot analysis for expression of some proteins. Results: Cell adhesion was inhibited especially between 20 and 50 uM of genistein treatment. Proliferation was reduced by 50% for treatments with 20 uM at 24 hours, with 20 or 50 uM at 48 and 50 uM at 72 hours (P<0.0001). Viability tests confirmed a proportional reduction in concentration of genistein and duration of treatments. Even cell migration was reduced significantly (P<0.001). Genistein down-regulates vitronectin, OCT4 and survivin. Conclusion: This in vitro study clarifies the anti-tumor effect of genistein on tongue carcinoma. In vivo studies are needed to confirm these data and develop a suitable delivery system that is capable of acting directly on tumor. PMID- 29180874 TI - Expression and significance of B7-H3 and Tie-2 in the tumor vasculature of clear cell renal carcinoma. AB - Tumor angiogenesis is required for tumor growth and metastasis, and the Ang/Tie-2 axis plays a pivotal role in angiogenesis. B7-H3, a new member of the B7 family of costimulatory molecules, has a critical function in the T-cell-mediated antitumor immune response, and abnormal tumor B7-H3 expression is frequently associated with a poor prognosis. However, the relationship between B7-H3 and angiogenesis in clear cell renal carcinoma (ccRCC) remains unclear. In this study, we used immunohistochemical methods to detect tumor vascular expression of B7-H3 and Tie-2 in tissue microarrays of 82 ccRCC patient samples. According to the results, B7-H3 is highly expressed in the tumor vascular endothelium of ccRCC and is associated with the ccRCC grade and tumor-node-metastasis (TNM) stage. Although vascular Tie-2 expression was also correlated with T stage and lymph node metastasis, it was not related to ccRCC grade or distant metastasis. The microvessel density (MVD) labeled by CD34 was correlated with tumor grade and TNM stage. Expression of B7-H3 and Tie-2 was positively correlated, and the levels were positively associated with the MVD. Additionally, immunofluorescence staining revealed coexpression of B7-H3 and Tie-2 in the vascular endothelia of ccRCC. Collectively, our findings suggest that expression of B7-H3 and Tie-2 in ccRCC tumor vasculature is closely related to the progression and prognosis of the disease. Furthermore, B7-H3 possibly promotes ccRCC angiogenesis through the Tie-2 pathway. Thus, B7-H3 might serve as an effective endothelial marker for ccRCC prognosis and become a promising target for ccRCC anti-angiogenic-targeted therapy. PMID- 29180875 TI - Effective treatment of low-dose decitabine in myelodysplastic syndrome/myeloproliferative neoplasms. AB - Objective: Primary myelofibrosis (PMF) is one of the Philadelphia negative myeloproliferative neoplasms (MPN). The main clinical features are obvious physical symptoms and symptomatic splenomegaly. It may be converse to leukemia and has a shortened life expectancy. Nowadays, the therapy for PMF is aimed at maintaining comfort and there is no curative treatment. PMF with myelodysplastic syndrome (MDS), called MDS/MPN-u, is rare and the treatment is complex. In this study, we want to discuss an effective treatment for MDS/MPN via a case report and literature review. Materials and methods: A female patient was diagnosed with MDS/MPN through bone marrow cytology, immunology, cell genetics, molecular biology, and pathology. She received thalidomide and prednisone as initial treatment. Ten months later, the first-line therapy had failed, she presented with clinically relevant pancytopenia and increased blasts in bone marrow. Because decitabine is one of the first-line treatments for MDS and the patient was frail, she received low-dose decitabine as second-line therapy. Decitabine was administered at 15 mg/m2 once a week for 3 weeks, in a 4 week cycle. If there was improvement the treatment interval was prolonged. Result: After one cycle, the blasts in bone marrow were decreased to 0.5%. After four cycles, she felt comfortable and hematological improvement was achieved. The treatment interval was prolonged. After eight cycles, the spleen reduced to 2 cm under the rib, and she achieved complete hematological remission. After ten cycles, the mutation of JAK2/V617F expression was decreased from 60.63% to 0.01%. During the therapy, the patient presented with grade III-IV hematological toxicity after the first two cycles, but there were no side effects after subsequent cycles. Conclusion: Our research showed that low-dose decitabine may be an effective treatment for MDS/MPN, especially in improving physical symptoms and achieving hematological remission. Besides, it may be possible to reverse positive JAK2 mutation. PMID- 29180876 TI - The effect of CYP2D6 *10 polymorphism on adjuvant tamoxifen in Asian breast cancer patients: a meta-analysis. AB - Objective: To evaluate the effect of CYP2D6 *10 polymorphism (C 100C>T, rs1065852) on clinical outcomes of female Asian breast cancer patients with tamoxifen adjuvant treatment. Methods: Meta-analysis of retrospective cohort studies published in July 2017 was performed. Fifteen studies with 1,794 Asian breast cancer patients were included, using strict eligibility requirements. Associations of disease-free survival (DFS), overall survival (OS) and recurrence rate after tamoxifen intake, with CYP2D6 *10 polymorphism were investigated through random effects models. Results: CYP2D6 *10 polymorphism was found to have effect on DFS and recurrence rate in various comparison models, but not on overall survival in the female Asian breast cancer patients. Conclusion: In conclusion, our meta-analysis suggests that significant association of *10/*10 (TT) genotype with poorer DFS and recurrence exists in female Asian breast cancer patients with tamoxifen 20 mg/day adjuvant treatment. In the future, large and well-designed studies are required to illustrate the interactions of CYP2D6 genetic variants, including *10 polymorphism and tamoxifen response on female breast cancer patients. PMID- 29180878 TI - Nimotuzumab combined with concurrent chemoradiotherapy benefits patients with advanced nasopharyngeal carcinoma. AB - Background: The potential benefits and possible risks associated with combined nimotuzumab and concurrent chemoradiotherapy in patients with advanced nasopharyngeal carcinoma (NPC) have yet to be determined. Methods: The databases PubMed, Web of Science, China National Knowledge Infrastructure, and Wanfang were systematically searched through February 2017 for studies comparing combined nimotuzumab and chemoradiotherapy versus chemoradiotherapy alone in the treatment of NPC. Primary outcomes were complete and partial responses, and the secondary outcome was adverse reactions. The random-effect model was used to pool relative risks (RRs) and 95% confidence intervals (CIs). Results: Nine randomized control trials and six cohort studies were included in the final analysis (n=1,015 patients). Compared with chemoradiotherapy alone, chemoradiotherapy combined with nimotuzumab was associated with an increased response rate (RR =1.11, 95% CI: 1.01-1.22). Combined treatment further reduced the occurrence rate of erythropenia (RR =0.11, 95% CI: 0.05-0.28) and neutropenia (RR =0.12, 95% CI: 0.05-0.27). The differences in the rates of other complications were not significant. Conclusion: Nimotuzumab combined with concurrent chemoradiotherapy is more effective in patients with advanced NPC than chemoradiotherapy alone. Patients receiving combination therapy did not have a higher rate of adverse reactions. Nimotuzumab can thus be recommended as an adjunct therapy in patients with advanced NPC. PMID- 29180877 TI - Clinical significance of CMTM4 expression in hepatocellular carcinoma. AB - CMTM4 is the most conserved member of chemokine-like factor (CKLF)-like MARVEL transmembrane domain-containing (CMTM) family on chromosome 16q22.1, a locus that harbors a number of tumor-suppressor genes. In previous studies, CMTM4 was reported to be downregulated and exhibited tumor-suppressor activities by regulating cell growth and cell cycle in clear cell renal cell carcinoma. However, its roles in tumorigenesis of hepatocellular carcinoma (HCC) remain poorly studied. This study first investigated the expression of CMTM4 in HCC, and then examined the association between the expression of CMTM4 with the clinicopathological features and prognosis of HCC patients. It was found that CMTM4 was downregulated in HCC tissues, compared with matched adjacent nontumor tissues, as detected by immunohistochemistry. In addition, Kaplan-Meier survival analysis showed that the negative expression of CMTM4 was associated with decreased overall survival rates in patients with HCC. The results of this study suggest CMTM4 plays a role as a tumor suppressor in HCC and CMTM4 negative expression is a risk factor for poor prognosis of HCC. PMID- 29180879 TI - Male occult triple-negative breast cancer with dermatomyositis: a case report and review of the literature. AB - Occult breast cancer is defined by the presence of axillary metastases without an identifiable primary breast tumor. Here, we report a rare case of a male occult breast cancer with dermatomyositis. We performed a modified radical mastectomy consisting of whole breast mastectomy and axillary lymph node dissection. Immunohistochemistry and fluorescent in situ hybridization analyses demonstrated an adenocarcinoma likely of breast origin, which was an occult triple-negative breast cancer. Interestingly, the patient's previously noted periorbital dermatomyositis resolved promptly following surgical excision. PMID- 29180880 TI - Identification of COX5B as a novel biomarker in high-grade glioma patients. AB - Background: Malignant glioma is the second leading cause of cancer-related death worldwide, and is known to exhibit a high degree of heterogeneity in its deregulation of different oncogenic pathways. The molecular subclasses of human glioma are not well known. Thus, it is crucial to identify vital oncogenic pathways in glioma with significant relationships to patient survival. Methods: In this study, we devised a bioinformatics strategy to map patterns of oncogenic pathway activation in glioma, from the Gene Expression Omnibus (GEO). Bioinformatics analysis revealed that 749 genes were differentially expressed and classified into different glioma grades. Results: Using gene expression signatures, we identified three oncogenic pathways (MAPK signaling pathway, Wnt signaling pathway, and ErbB signaling pathway) deregulated in the majority of human glioma. Following gene microarray analysis, the gene expression profile in the differential grade glioma was further validated by bioinformatic analyses, with coexpression network construction. Furthermore, we found that cytochrome c oxidase subunit Vb (COX5B), the terminal enzyme of the electron transport chain, was the central gene in a coexpression network that transfers electrons from reduced cytochrome c to oxygen and, in the process, generates an electrochemical gradient across the mitochondrial inner membrane. The expression level of COX5B was then detected in 87 glioma tissues as well as adjacent normal tissues using immunohistochemistry. We found that COX5B was significantly upregulated in 67 of 87 (77.0%) glioma and glioblastoma tissues, compared with adjacent tissue (p<0.01). Furthermore, statistical analysis showed the COX5B expression level was significantly associated with clinical stage and lymph node status, while there were no correlations between COX5B expression and age or tumor size. Conclusion: These data indicate that COX5B may be implicated in glioma pathogenesis and as a biomarker for identification of the pathological grade of glioma. PMID- 29180881 TI - Curcumin potentiates the potent antitumor activity of ACNU against glioblastoma by suppressing the PI3K/AKT and NF-kappaB/COX-2 signaling pathways. AB - Glioblastoma (GBM) is a highly invasive and challenging primary tumor of the central nervous system (CNS), and currently available treatments provide limited benefits to patients with this disease. Therefore, the development of novel therapeutic targets and effective treatment strategies is essential. Nimustine hydrochloride (ACNU) is widely used as the standard chemotherapeutic agent and is frequently administered together with other chemotherapeutic agents in clinical studies. Curcumin, a natural polyphenolic compound, could potentially be combined with chemotherapeutics for cancer treatment; however, there are no reports of studies where ACNU and curcumin were combined for GBM treatment, and the mechanisms underlying their activity remain poorly understood. In the present study, we investigated the effects of combined treatment with curcumin and ACNU on GBM cells and found that it significantly enhanced the inhibition of cell proliferation, colony formation, migration, and invasion. In addition, co treatment with curcumin increased ACNU-induced apoptosis through enhancing the release of cytochrome c from the mitochondrial intermembrane space into the cytosol. Further, curcumin and ACNU acted synergistically in their antitumor effects by targeting N-cadherin/MMP2/9, PI3K/AKT, and NF-kappaB/COX-2 signaling. These results indicate that curcumin can enhance the anti-proliferation, anti migration, and proapoptotic activities of ACNU against GBM, and provide strong evidence that combined treatment with curcumin and ACNU has the potential to be an effective therapeutic option for GBM. PMID- 29180882 TI - Cytomembranic PD-L1 expression in locoregionally advanced nasopharyngeal carcinoma. AB - Background and objective: The aim of this study was to evaluate the expression of cytomembranic programmed death-ligand 1 (PD-L1) and its clinical significance in locoregionally advanced nasopharyngeal carcinoma (NPC). Patients and methods: Formalin-fixed, paraffin-embedded tissue biopsies from 85 patients with histological diagnosis of locoregionally advanced NPC treated with radical intensity-modulated radiotherapy and concurrent cisplatin-based chemotherapy were studied. By using immunohistochemistry staining, expressions of cytomembranic PD L1 on tumor cells were detected. Results: After a median follow-up duration of 65.8 months, 7 (8.2%), 5 (5.9%), and 5 (5.9%) patients suffered from local failure, regional failure, and distant metastases, respectively. The 5-year local failure-free survival, regional failure-free survival, distant failure-free survival, and overall survival (OS) rates were 90.9%, 94.8%, 94.0%, and 92.2%, respectively. Our results revealed that a high expression of cytomembranic PD-L1 was correlated with shorter OS (5y-OS: 82.5% vs 97.6%, P=0.022). In the multivariate analysis, only the cytomembranic PD-L1 was an independent prognostic factor for OS (hazard ratio: 6.176, 95% confidence interval, 1.166-32.710, P=0.032). Conclusion: Cytomembranic PD-L1 expression levels correlated with OS in locoregionally advanced NPC. Agreement between different methods is needed for further application of PD-L1 biomarker assays in NPC. PMID- 29180883 TI - Erratum: Toll-like receptors 7 and 8 expression correlates with the expression of immune biomarkers and positively predicts the clinical outcome of patients with melanoma [Corrigendum]. AB - [This corrects the article on p. 4339 in vol. 10, PMID: 28919783.]. PMID- 29180885 TI - Long-term effect of the insoluble thread-lifting technique. AB - Background: Although the thread-lifting technique for sagging faces has become more common and popular, medical literature evaluating its effects is scarce. Studies on its long-term prognosis are particularly uncommon. Patients and methods: One hundred individuals who had previously undergone insoluble thread lifting were retrospectively investigated. Photos in frontal and oblique views from the first and last visits were evaluated by six female individuals by guessing the patients' ages. The mean guessed age was defined as the apparent age, and the difference between the real and apparent ages was defined as the youth value. The difference between the youth values before and after the thread lift was defined as the rejuvenation effect and analyzed in relation to the time since the operation, the number of threads used and the number of thread-lift operations performed. Results: The rejuvenation effect decreased over the first year after the operation, but showed an increasing trend thereafter. The rejuvenation effect increased with the number of threads used and the number of thread-lift operations performed. Conclusion: The insoluble thread-lifting technique appears to be associated with both early and late effects. The rejuvenation effect appeared to decrease during the first year, but increased thereafter. A multicenter trial is necessary to confirm these findings. PMID- 29180884 TI - Redefining face contour with a novel anti-aging cosmetic product: an open-label, prospective clinical study. AB - Background: Skin aging is accelerated by multiple extrinsic factors: ultraviolet radiation, smoking and pollution increase oxidative activity, damaging cellular and extracellular components such as DNA, proteins, and lipids. With age, collagen and hyaluronic acid levels decline, resulting in loss of elasticity and moisture of the skin. Over time this damage leads to characteristic signs that make the skin look older: altered facial contour, sagging skin, wrinkles, and an uneven complexion. This study evaluated the anti-aging effects of a new facial cream formulated with carnosine, Alteromonas ferment extract, crosspolymer hyaluronic acid, and a tripeptide. Methods: An open-label intra-individual study to assess the anti-aging efficacy of the investigational product in 33 women aged 45 to 65 years. The product was applied twice daily for 56 days. Facial contour and skin deformation, elasticity, hydration, and complexion were measured with specialized equipment at baseline and days 28 and 56. Additionally, subjects completed questionnaires at days 28 and 56 on the perceived efficacy and cosmetic characteristics of the product. Results: After 56 days of use of the investigational product, a redefining effect was observed, with a significant decrease in sagging jawline (7%). Skin was significantly more hydrated (12%), firmer (29%), and more elastic (20%) (P<0.001 for all). On complexion assessment, skin texture (a measure of skin smoothness) and spots (brown and red skin lesions) also improved significantly (12% and 6% decrease, respectively). In the subjective self-evaluation, the majority of subjects reported that the skin was visibly tightened and more elastic, flexible, and moisturized (91%, 88%, 91%, and 90%, respectively). The product was well tolerated with no adverse events reported during the study. Conclusion: This new cosmetic product demonstrated anti-aging effects after 56 days of use, most notably a redefined facial contour and improved complexion. It is a safe and effective anti-aging product. PMID- 29180886 TI - Next generation of biologics for the treatment of Crohn's disease: an evidence based review on ustekinumab. AB - The limited efficacy of the currently available medical therapies in a proportion of patients with Crohn's disease has led to the research and development of molecules that can block new inflammatory pathways. Ustekinumab is a fully human IgG1 monoclonal antibody which targets the common p40 subunit of the cytokines interleukin-12 as well as interleukin-23. Consequently, the Th1 and Th17 inflammatory responses are inhibited. Ustekinumab has been recently approved for its use in patients with Crohn's disease. Its efficacy and safety was initially proved in patients with psoriasis and psoriatic arthritis. More recently, three Phase III trials have confirmed its efficacy in patients with Crohn's disease refractory to anti-tumor necrosis factor therapy. This biologic agent appears safe, with no increased risk of infectious or malignant complications, and a low immunogenic profile. PMID- 29180888 TI - Association between serum concentration of 25-hydroxyvitamin D and community acquired pneumonia: a case-control study. AB - Background: Community-acquired pneumonia (CAP) is a common disease with significant morbidity and mortality. There is evidence that vitamin D deficiency can be associated with infectious diseases. The aim of this study was to compare the levels of vitamin D between patients with CAP and healthy controls. Methods: In a case-control study on 73 patients with CAP and 76 healthy controls, the serum concentration of 25-hydroxyvitamin D (25[OH]D) was measured. Severity and outcomes of disease and also duration of hospital stay were compared in patients with different levels of 25(OH)D. The severity of CAP was assessed using the CURB 65 score (confusion, uremia, respiratory rate, low blood pressure, age >=65 years) and was also reflected by the length of hospital stay, admission to intensive care unit (ICU), and 30-day mortality. Results: In total, 81.2% of the study population had vitamin D levels <30 ng/dL. The risk of pneumonia among subjects with deficient vitamin D levels was 3.69 (95% CI: 1.46, 9.31) times of those with sufficient vitamin D level (P=0.006). Prevalence of severe deficiency of vitamin D in scores three and four of CURB-65 (59.38%), was far more than scores one and two (31.71%). Also, results indicated patients with severe deficiency had a higher risk for ICU admission, 30-day mortality, and longer hospitalization stay, but these were not statistically significant. Conclusion: According to findings, a low level of 25(OH)D is associated with a higher incidence of CAP and more severe disease. It is recommended to pay more attention to vitamin D deficiency in infectious diseases, particularly in CAP patients. PMID- 29180887 TI - Ingested capsaicinoids can prevent low-fat-high-carbohydrate diet and high-fat diet-induced obesity by regulating the NADPH oxidase and Nrf2 pathways. AB - Objective: Capsaicinoids (CAPs), most commonly found in chili peppers, have a multitude of pharmacological and physiological effects, such as anti inflammation, antioxidant, and anticancer effects. In the present study, we set out to investigate the hypothesis that CAPs mitigate obesity in rats and the possible mechanisms thereof. Materials and methods: Rats were divided into six groups, including control (+/-10 mg CAPs/kg body weight [BW]), low-fat-high sucrose diet (+/-10 mg CAPs/kg BW), and high-fat diet (+/-10 mg CAPs/kg BW). Blood samples and liver and aortic tissues were taken at the end of the study. Results: CAPs supplementation significantly reduced hyperglycemia and hyperlipidemia (P<0.001) and ameliorated oxidative damage by reducing malondialdehyde concentrations in serum and liver and by increasing total antioxidant capacity in serum induced by the low-fat-high-sucrose and high-fat diets (P<0.001 for all). CAPs also depressed levels of NFkappaB p65, gp91phox, and p22phox, essential components of NADPH oxidase, in the aorta of rats. However, levels of Nrf2, Sirt1, and endothelial nitric oxide synthase were significantly increased in the aorta. Conclusion: CAPs may at least partially reduce adverse effects due to high-fat diet and sucrose consumption through regulation of energy metabolism, oxidative stress, and proteins involved in vasoprotection. PMID- 29180889 TI - Risk of respiratory depression with opioids and concomitant gabapentinoids. AB - Introduction: The combination of opioids and central nervous system depressants such as benzodiazepines and barbiturates has an additive effect on the frequency of oversedation and respiratory depression requiring naloxone use in hospitalized patients. Gabapentinoids (gabapentin and pregabalin) are frequently prescribed with opioids for their opioid-sparing and adjuvant analgesic effects. There is limited literature on the risk of respiratory depression due to the combination of opioids and gabapentinoids requiring naloxone administration. Methods: This retrospective study evaluated patients who were prescribed opioids and at least one dose of naloxone between March 1, 2014 and September 30, 2016. The primary objective of this study was to compare the frequency of respiratory depression among patients who received naloxone and opioids (non-gabapentinoid group) with those who received naloxone, opioids, and gabapentinoids (gabapentinoid group). Secondary objectives included comparing the association of oversedation, using the Pasero Opioid-induced Sedation Scale, and various risk factors with those in the gabapentinoid group. Results: A total of 153 patient episodes of naloxone administration (102 in the non-gabapentinoid and 51 in the gabapentinoid groups) in 125 unique patients were included in the study. For the primary objective, there were 33 episodes of respiratory depression associated with the non gabapentinoid group (33/102=32.4%) versus 17 episodes of respiratory depression with the gabapentinoid group (17/51=33.3%) (p=0.128). Secondary objectives showed a significant association between respiratory depression and surgery in the previous 24 hours (p=0.036) as well as respiratory depression and age >65 years (p=0.031) for patients in the non-gabapentinoid group compared to the gabapentinoid group. Conclusion: There was no significant association of respiratory depression in the gabapentinoid group versus the non-gabapentinoid group. There was an increased risk of respiratory depression in the gabapentinoid group, specifically in patients who had surgery within the previous 24 hours. PMID- 29180890 TI - A retrospective study on analgesic requirements for thoracoscopic surgery postoperative pain. AB - Background: Thoracoscopic surgery (TS) has been performed as a minimally invasive procedure since the beginning of the 1990s. This has led to a dramatic change in the postoperative condition of these patients, facilitating early ambulation and easier management of postoperative pain. However, empirical evidence on postoperative pain management after TS is limited. The aims of this study were to determine the efficacy and adequacy of postoperative analgesic medications and to simplify the choice of additional drugs based on a numerical rating scale (NRS). Materials and methods: A retrospective study of patients who underwent TS was performed to evaluate postoperative pain, analgesia requirements, and the number of drugs needed during the perioperative period based on the NRS score. Results: Of the 524 patients, mild pain was noted in 87% patients on the day of the operation and in 75.6% patients on ambulation. The mean NRS score was 1.83+/-1.49 on the day of the operation and 2.73+/-1.75 on ambulation. An NRS score of 3 on both the day of operation and on ambulation was defined as the necessary condition for improved pain management. Multivariate analysis showed that high surgical stress significantly influenced pain scores. Reduction in pain with an NRS score of >=1 was significant with the addition of pentazocine hydrochloride (p<0.01) and flurbiprofen (p<0.01). Interestingly, the addition of tramadol was borderline efficacious (p=0.05) in patients with an NRS score of >3 on ambulation. Conclusion: A small number of patients have moderate-to-severe pain after TS. Tramadol demonstrated borderline efficacy in controlling postoperative intense pain with an NRS score of >=3. PMID- 29180891 TI - Effect of oxycodone patient-controlled intravenous analgesia after cesarean section: a randomized controlled study. AB - Background: Oxycodone is a semisynthetic MU-opioid receptor agonist with a potentially good analgesic efficacy in visceral pain. This study aims to compare the efficacy of oxycodone with sufentanil patient-controlled intravenous analgesia (PCIA). Methods: One hundred and twenty primiparas undergoing elective cesarean section were randomized into four groups by different drugs of PCIA: group S (sufentanil 100 MUg), group OS1 (sufentanil 70 MUg, oxycodone 30 mg), group OS2 (sufentanil 50 MUg, oxycodone 50 mg), and group O (oxycodone 100 mg). Ramosetron 0.3 mg was added to each group. In all groups, drugs were diluted to 100 mL and managed with a continuous infusion of 1 mL.h-1, a bolus dose of 2 mL, and a lockout interval of 15 min. The maximum dose of PCIA per hour was 10 mL. After surgery, pain scores, PCIA doses, and side effects were compared among groups. Results: At all time points (6, 12, and 24 h after surgery), Numerical Rating Scale (NRS) of uterine cramping pain (NRS-U) scores in group O were lower than those in groups OS1 and S (P<0.008) and NRS-U scores in groups OS2 and OS1 were lower than that in group S (P<0.008). NRS of moving into the sitting position (NRS-S) scores in group O were lower than those in the other groups (P<0.008). NRS-S scores in group OS2 were lower than those in groups OS1 and S (P<0.008). At 12 and 24 h after surgery, NRS of incision pain at rest (NRS-R) scores in group O were lower than those in the other groups (P<0.008). At all time points, NRS-R scores in group OS2 were lower than those in groups OS1 and S (P<0.008). The number of PCIA boluses and amount of opioid consumption in group O were lower than those in groups OS1 and S at all time points (P<0.008). Conclusion: Oxycodone PCIA may be more effective than sufentanil PCIA for pain relief after cesarean section but the incidence of side effects needs further investigation. PMID- 29180892 TI - Does self-perception of sensitivity to pain correlate with actual sensitivity to experimental pain? AB - Background: People often state that they are "sensitive" or "insensitive" to pain. However, the accuracy and clinical relevance of such statements is unclear. Objective: The aim of this study was to search for associations between self perception of sensitivity to pain and experimental pain measures, including known psychophysical inhibitory or excitatory pain paradigms. Subjects and methods: Subjective sensitivity to pain was reported by 75 healthy participants and included three self-perceived variables: pain threshold, pain sensitivity and pain intensity in response to a hypothetical painful event (hypothetical pain intensity [HPI]). Experimental pain measures consisted of thermal pain threshold ( degrees C), suprathreshold thermal pain intensity (Visual Analog Scale, 0-100) and the psychophysical paradigms of conditioned pain modulation (CPM) and temporal summation (TS), representing inhibitory and excitatory pain processes, respectively. Results: No significant correlations were found between self perceived pain threshold or pain sensitivity and any of the experimental pain measures. In contrast, the reported HPI correlated with thermal pain threshold (r = -0.282; p = 0.014), suprathreshold thermal pain intensity (r = 0.367; p = 0.001) and CPM (r = 0.233; p = 0.044), but not with TS. Conclusion: Self perception of pain sensitivity articulated by intangible expressions such as pain threshold or pain sensitivity is unrelated to actual sensitivity to experimental pain. In contrast, when measured by intensity of a hypothetical painful event (HPI), sensitivity to pain is associated with some, but not all, experimental pain reports. Further studies are needed for better understanding of these associations and their potential clinical significance. PMID- 29180893 TI - Identification of key genes and pathways associated with neuropathic pain in uninjured dorsal root ganglion by using bioinformatic analysis. AB - Purpose: Neuropathic pain is a complex chronic condition occurring post-nervous system damage. The transcriptional reprogramming of injured dorsal root ganglia (DRGs) drives neuropathic pain. However, few comparative analyses using high throughput platforms have investigated uninjured DRG in neuropathic pain, and potential interactions among differentially expressed genes (DEGs) and pathways were not taken into consideration. The aim of this study was to identify changes in genes and pathways associated with neuropathic pain in uninjured L4 DRG after L5 spinal nerve ligation (SNL) by using bioinformatic analysis. Materials and methods: The microarray profile GSE24982 was downloaded from the Gene Expression Omnibus database to identify DEGs between DRGs in SNL and sham rats. The prioritization for these DEGs was performed using the Toppgene database followed by gene ontology and pathway enrichment analyses. The relationships among DEGs from the protein interactive perspective were analyzed using protein-protein interaction (PPI) network and module analysis. Real-time polymerase chain reaction (PCR) and Western blotting were used to confirm the expression of DEGs in the rodent neuropathic pain model. Results: A total of 206 DEGs that might play a role in neuropathic pain were identified in L4 DRG, of which 75 were upregulated and 131 were downregulated. The upregulated DEGs were enriched in biological processes related to transcription regulation and molecular functions such as DNA binding, cell cycle, and the FoxO signaling pathway. Ctnnb1 protein had the highest connectivity degrees in the PPI network. The in vivo studies also validated that mRNA and protein levels of Ctnnb1 were upregulated in both L4 and L5 DRGs. Conclusion: This study provides insight into the functional gene sets and pathways associated with neuropathic pain in L4 uninjured DRG after L5 SNL, which might promote our understanding of the molecular mechanisms underlying the development of neuropathic pain. PMID- 29180894 TI - Cortical mapping of painful electrical stimulation by quantitative electroencephalography: unraveling the time-frequency-channel domain. AB - The goal of this study was to capture the electroencephalographic signature of experimentally induced pain and pain-modulating mechanisms after painful peripheral electrical stimulation to determine one or a selected group of electrodes at a specific time point with a specific frequency range. In the first experiment, ten healthy participants were exposed to stimulation of the right median nerve while registering brain activity using 32-channel electroencephalography. Electrical stimulations were organized in four blocks of 20 stimuli with four intensities - 100%, 120%, 140%, and 160% - of the electrical pain threshold. In the second experiment, 15 healthy participants received electrical stimulation on the dominant median nerve before and during the application of a second painful stimulus. Raw data were converted into the time frequency domain by applying a continuous wavelet transform. Separated domain information was extracted by calculating Parafac models. The results demonstrated that it is possible to capture a reproducible cortical neural response after painful electrical stimulation, more specifically at 250 milliseconds poststimulus, at the midline electrodes Cz and FCz with predominant delta oscillations. The signature of the top-down nociceptive inhibitory mechanisms is delta-activity at 235 ms poststimulus at the prefrontal electrodes. This study presents a methodology to overcome the a priori determination of the regions of interest to analyze the brain response after painful electrical stimulation. PMID- 29180895 TI - Postoperative pain management in the postanesthesia care unit: an update. AB - Acute postoperative pain remains a major problem, resulting in multiple undesirable outcomes if inadequately controlled. Most surgical patients spend their immediate postoperative period in the postanesthesia care unit (PACU), where pain management, being unsatisfactory and requiring improvements, affects further recovery. Recent studies on postoperative pain management in the PACU were reviewed for the advances in assessments and treatments. More objective assessments of pain being independent of patients' participation may be potentially appropriate in the PACU, including photoplethysmography-derived parameters, analgesia nociception index, skin conductance, and pupillometry, although further studies are needed to confirm their utilities. Multimodal analgesia with different analgesics and techniques has been widely used. With theoretical basis of preventing central sensitization, preventive analgesia is increasingly common. New opioids are being developed with minimization of adverse effects of traditional opioids. More intravenous nonopioid analgesics and adjuncts (such as dexmedetomidine and dexamethasone) are introduced for their opioid-sparing effects. Current evidence suggests that regional analgesic techniques are effective in the reduction of pain and stay in the PACU. Being available alternatives to epidural analgesia, perineural techniques and infiltrative techniques including wound infiltration, transversus abdominis plane block, local infiltration analgesia, and intraperitoneal administration have played a more important role for their effectiveness and safety. PMID- 29180896 TI - Checkpoint blockade in solid tumors and B-cell malignancies, with special consideration of the role of CD200. AB - In the ontogeny of a normal immune response, a series of checkpoints must be overcome to ensure that unwanted and/or harmful self-directed activation responses are avoided. Many of the molecules now known to be active in this overseeing of the evolving immune activation cascade, contributing inhibitory signals to dampen an overexuberant response, belong to the immunoglobulin supergene family. These include members of the CD28/CTLA-4:B7.1/B7.2 receptor/ligand family, PD-1 and PDL-1, CD200 and CD200R, and the more recently described V-domain immunoglobulin suppressor of T-cell activation and its ligand (VSIG-3/IGSF11). Unfortunately, from the point of view of improving immunotargeting of cancer cells, triggering these checkpoint inhibitory signaling pathways, so necessary to maintain self-tolerance, simultaneously acts to prevent effective tumor immunity. The recent development of reagents, predominantly antibodies, to act as checkpoint blockade agents, has had a dramatic effect on human cancer treatment, with a marked reported success for anti-CTLA-4 and PD-1 in particular in clinical trials. This review provides a general overview of the data now available showing the promise of such treatments to our cancer armamentarium and elaborates in depth on the potential promise of what can be regarded as an underappreciated target molecule for checkpoint blockade in chronic lymphocytic leukemia and solid tumors, CD200. PMID- 29180897 TI - Prognostic value of site-specific metastases and therapeutic roles of surgery for patients with metastatic bladder cancer: a population-based study. AB - Background: We aimed to evaluate the prognostic value of site-specific metastases in patients with metastatic bladder cancer and analyze the roles that surgeries play in the treatment of this malignancy. Materials and methods: A population based retrospective study using Surveillance, Epidemiology and End Results dataset was performed and metastatic bladder cancer patients were classified according to the sites of metastases (bone, brain, liver, lung and distant lymph nodes). Kaplan-Meier analysis with log-rank test was used for survival comparisons. Multivariate Cox regression model was employed to analyze the effect of distant metastatic sites on overall survival (OS) and cancer-specific survival (CSS). Results: A total of 1862 patients with metastatic bladder cancer from 2010 to 2014 were identified. Bone, lung and distant lymph nodes were the most common metastatic sites. Patients with bone, brain, liver and lung involvement had worse OS and CSS compared to patients without the corresponding sites of metastases. Multivariate analysis showed that bone, brain, liver and lung metastases were independent prognostic factors for both OS and CSS, while distant node metastasis was not. Moreover, patients with a single metastatic site had more favorable OS (p<0.001) and CSS (p<0.001) than patients with multisite metastases. Among single site metastatic patients, distant nodes and liver metastases represented the best and the worst prognosis, respectively. Moreover, radical cystectomy was an independent predictor for better OS and CSS, while in patients with liver metastasis and multiple metastatic sites, RC did not bring benefits. Besides, in patients with a single metastatic site, metastasectomy seemed to be associated with favorable OS (p=0.042), especially for patients with age <65 years (p=0.006) and for muscle-invasive bladder cancer patients (p=0.031). Conclusion: Distant metastatic sites have differential impact on survival outcomes in patients with metastatic bladder cancer. Surgeries, including radical cystectomy and metastasectomy, might still lead to survival benefits for highly selected patients. PMID- 29180898 TI - Risk factors for hypocalcemia and hypoparathyroidism following thyroidectomy: a retrospective Chinese population study. AB - Background: Hypocalcemia is one of the most common postoperative complications following thyroid surgery in clinical practice. The occurrence of hypocalcemia is mainly attributed to hypoparathyroidism when parathyroid glands are devascularized, injured, or dissected during the surgery. The aim of this study was to analyze the risk factors for hypocalcemia and hypoparathyroidism following thyroidectomy. Patients and methods: A total of 278 patients who underwent thyroid surgery were analyzed retrospectively. Univariate analysis and multivariable logistic regression were performed to discover the risk factors for hypocalcemia and hypoparathyroidism. Results: Postoperative hypocalcemia occurred in 76 (27.3%) patients and hypoparathyroidism occurred in 42 (15.1%) patients. Seven factors were significantly related to the presence of postoperative hypocalcemia, namely, age (P=0.049), gender (P=0.015), lateral lymph node dissection (P=0.017), operation type (P<0.001), preoperative parathyroid hormone (PTH) level (P=0.035), operation time (P=0.001), and applying carbon nanoparticles (CNs; P=0.007). Our result revealed that gender (P=0.014), lateral lymph node dissection (P=0.038), operation type (P<0.001), operative time (P<0.001), and applying CNs (P=0.001) had a significant correlation with postoperative hypoparathyroidism. Conclusion: These findings were crucial for guiding surgeons to prevent the occurrence of hypocalcemia and hypoparathyroidism. PMID- 29180899 TI - Expression of minichromosome maintenance genes in renal cell carcinoma. AB - Minichromosome maintenance (MCM) proteins play an essential role in DNA replication. They have been shown to be overexpressed in various types of cancer. However, the role of this family in renal cell carcinoma (RCC) is widely unknown. In this study, we have identified a number of RCC datasets in the Gene Expression Omnibus database and also investigated the correlation between the expression levels of MCM genes and clinicopathological parameters. We found that the expression levels of MCM genes are positively correlated with one another. Expression levels of MCM2, MCM5, MCM6, and MCM7, but not of MCM3 and MCM4, were higher in RCC compared to paired adjacent normal tissue. Only the expression level of MCM4, but not of other MCMs, was positively correlated with tumor grade. In addition, a high-level expression of MCM2 in either primary tumor or metastases of RCC predicted a shorter disease-free survival time, while a high level expression of MCM4 or MCM6 in primary tumor was also associated with poorer disease-free survival. Interestingly, we also demonstrated that patients with their primary RCC overexpressing 2 or more MCM genes had a shorter disease-free survival time, while those with RCC metastases overexpressing 3 or more MCM genes had a shorter disease-free survival. Importantly, we also demonstrated that overexpression of MCM genes is an independent predictor for survival in RCC patients. Our results suggest that MCM2-7 genes may be an important prognostic marker for patients with RCC. PMID- 29180900 TI - Association between unilateral or bilateral mastectomy and breast cancer death in patients with unilateral ductal carcinoma. AB - Background: Utilization of bilateral mastectomy for unilateral breast cancer is increasing despite cost and surgical risks with conflicting reports of survival benefit. Current studies evaluating death after bilateral mastectomy have included patients treated both with breast conservation therapy and unilateral mastectomy. In this study, we directly compared breast cancer-specific death of patients who underwent bilateral or unilateral mastectomy for unilateral breast cancer using a matched cohort analysis. Methods: This was an observational study of women diagnosed with unilateral breast cancer from 1998 through 2002, using the Surveillance, Epidemiology, and End Results (SEER) database. A 4-to-1 matched cohort of patients was selected including 14,075 patients. Mortality of the groups was compared using Cox proportional hazards models for cause-specific death. Results: A total of 41,510 patients diagnosed with unilateral breast cancer were included. Unilateral mastectomy was performed in 93% of patients, while bilateral mastectomy was performed in the remaining 7% of patients. When 4 to-1 matching was performed, 11,260 unilateral mastectomy and 2,815 bilateral mastectomy patients were included. Patients with bilateral mastectomy did not have a significantly lower hazard of breast cancer-specific death when compared with patients with unilateral mastectomy (hazard ratio: 0.92 vs 1.00, p=0.11). Conclusion: Bilateral mastectomy did not provide a clinically or statistically significant breast cancer-specific mortality benefit over unilateral mastectomy based on a matched cohort analysis of a nationwide population database. These findings should be interpreted in the context of patient preference and alternative benefits of bilateral mastectomy. PMID- 29180901 TI - Enhanced recovery programs in lung cancer surgery: systematic review and meta analysis of randomized controlled trials. AB - Background: Enhanced recovery after surgery (ERAS) program is an effective evidence-based multidisciplinary protocol of perioperative care, but its roles in thoracic surgery remain unclear. This systematic review of randomized controlled trials (RCTs) aims to investigate the efficacy and safety of the ERAS programs for lung cancer surgery. Materials and methods: We searched the PubMed and EMBASE databases to identify the RCTs that implemented an ERAS program encompassing more than four care elements within at least two phases of perioperative care in lung cancer surgery. The heterogeneity levels between studies were estimated by the Cochrane Collaborations. A qualitative review was performed if considerable heterogeneity was revealed. Relative risk (RR) and weighted mean difference served as the summarized statistics for the meta-analyses. Additional analyses were also performed to perceive potential bias risks. Results: A total of seven RCTs enrolling 486 patients were included. The meta-analysis indicated that the ERAS group patients had significantly lower morbidity rates (RR=0.64; p<0.001), especially the rates of pulmonary (RR=0.43; p<0.001) and surgical complications (RR=0.46; p=0.010), than those of control group patients. No significant reduction was found in the in-hospital mortality (RR=0.70; p=0.58) or cardiovascular complications (RR=1.46; p=0.25). In the qualitative review, most of the evidence reported significantly shortened length of hospital and intensive care unit stay and decreased hospitalization costs in the ERAS-treated patients. No significant publication bias was detected in the meta-analyses. Conclusion: Our review demonstrates that the implementation of an ERAS program for lung cancer surgery can effectively accelerate postoperative recovery and save hospitalization costs without compromising patients' safety. A worldwide consensus guideline is urgently required to standardize the ERAS protocols for elective lung resections in the future. PMID- 29180902 TI - Validation of algorithms to determine incidence of Hirschsprung disease in Ontario, Canada: a population-based study using health administrative data. AB - Objective: Incidence rates of Hirschsprung disease (HD) vary by geographical region, yet no recent population-based estimate exists for Canada. The objective of our study was to validate and use health administrative data from Ontario, Canada to describe trends in incidence of HD between 1991 and 2013. Study design: To identify children with HD we tested algorithms consisting of a combination of diagnostic, procedural, and intervention codes against the reference standard of abstracted clinical charts from a tertiary pediatric hospital. The algorithm with the highest positive predictive value (PPV) that could maintain high sensitivity was applied to health administrative data from April 31, 1991 to March 31, 2014 (fiscal years 1991-2013) to determine annual incidence. Temporal trends were evaluated using Poisson regression, controlling for sex as a covariate. Results: The selected algorithm was highly sensitive (93.5%) and specific (>99.9%) with excellent predictive abilities (PPV 89.6% and negative predictive value >99.9%). Using the algorithm, a total of 679 patients diagnosed with HD were identified in Ontario between 1991 and 2013. The overall incidence during this time was 2.05 per 10,000 live births (or 1 in 4,868 live births). The incidence did not change significantly over time (odds ratio 0.998, 95% confidence interval 0.983-1.013, p = 0.80). Conclusion: Ontario health administrative data can be used to accurately identify cases of HD and describe trends in incidence. There has not been a significant change in HD incidence over time in Ontario between 1991 and 2013. PMID- 29180903 TI - Prescription duration and treatment episodes in oral glucocorticoid users: application of the parametric waiting time distribution. AB - Purpose: Glucocorticoids are widely used medications. In many pharmacoepidemiological studies, duration of individual prescriptions and definition of treatment episodes are important issues. However, many data sources lack this information. We aimed to estimate duration of individual prescriptions for oral glucocorticoids and to describe continuous treatment episodes using the parametric waiting time distribution. Methods: We used Danish nationwide registries to identify all prescriptions for oral glucocorticoids during 1996 2014. We applied the parametric waiting time distribution to estimate duration of individual prescriptions each year by estimating the 80th, 90th, 95th and 99th percentiles for the interarrival distribution. These corresponded to the time since last prescription during which 80%, 90%, 95% and 99% of users presented a new prescription for redemption. We used the Kaplan-Meier survival function to estimate length of first continuous treatment episodes by assigning estimated prescription duration to each prescription and thereby create treatment episodes from overlapping prescriptions. Results: We identified 5,691,985 prescriptions issued to 854,429 individuals of whom 351,202 (41%) only redeemed 1 prescription in the whole study period. The 80th percentile for prescription duration ranged from 87 to 120 days, the 90th percentile from 116 to 150 days, the 95th percentile from 147 to 181 days, and the 99th percentile from 228 to 259 days during 1996-2014. Based on the 80th, 90th, 95th and 99th percentiles of prescription duration, the median length of continuous treatment was 113, 141, 170 and 243 days, respectively. Conclusion: Our method and results may provide an important framework for future pharmacoepidemiological studies. The choice of which percentile of the interarrival distribution to apply as prescription duration has an impact on the level of misclassification. Use of the 80th percentile provides a measure of drug exposure that is specific, while the 99th percentile provides a sensitive measure. PMID- 29180904 TI - Quality of oral surgery referrals and how to improve them. AB - Aim: To assess the quality of routine oral surgery referrals received at Halmstad Hospital and Vaxjo Hospital and to emphasize areas for improvement. Method: A retrospective study was performed on all routine oral surgery referrals received between 2014 and 2015 at both Halmstad Hospital and Vaxjo Hospital. A total of 1,891 referral letters were assessed for their quality against a predetermined checklist of basic requirements of a satisfactory referral. The referrals were also categorized according to if it was sent by a male, female, private dental service, or the Swedish Public Dental Health service. Results: A diagnosis was missing in 30% of all referrals. Radiographs and information about previous radiographic examinations were not included in 10% of the referrals. Of those referrals that included radiographs, only around half were deemed adequate for diagnostic purposes. The presenting complaint was missing in 40% of all referrals. Current medical history was absent in 40% and current medication was omitted in 60% of the referrals. Information about tobacco use was only included in 10% of all referrals. Overall, female referrers performed better than male colleagues. Private referrals more regularly included information about diagnosis, previous treatment, and current medication. On the other hand, referrals from the public dental health service more frequently included radiographs, tobacco use, and current medical history. Conclusion: There is plenty of room for improving the standards of oral surgery referrals. We suggest that future electronic referral systems should only allow for submission once all of the essential information has been considered. PMID- 29180905 TI - Effects of minodronate in postmenopausal women with osteoporosis who received prior treatment with raloxifene. AB - Background: In clinical practice, patients with postmenopausal osteoporosis have often shown a poor response to treatment with an antiresorptive agent for several years. The purpose of this study was to investigate the efficacy of switching raloxifene with minodronate in patients who responded poorly to the treatment of postmenopausal osteoporosis with raloxifene. Patients and methods: This observational study was conducted based on a single-arm, non-randomized, open label design and was approved by the institute's institutional review board. Postmenopausal women with osteoporosis who became unresponsive in terms of bone mineral density (BMD) after being administered raloxifene for two or more years were enrolled. Patients were treated with 1 mg minodronate daily or 50 mg minodronate monthly. Changes in BMD and serum bone turnover markers were monitored at baseline, 6, 12, and 24 months after switching treatment. Results: Twenty-seven patients were enrolled. Two discontinued treatment because of adverse events related to the study drug. Among the remaining 25 patients, lumbar BMD significantly increased by 3.67%, 5.08%, and 6.97% at 6, 12, and 24 months, respectively, and femoral neck BMD increased by 1.63%, 2.18%, and 3.85% at 6, 12, and 24 months, respectively. Serum bone-specific alkaline phosphatase showed a significant reduction of 30.35% from the baseline (p<0.0001) within the first 6 months, suggesting a stronger antiresorptive effect of minodronate. Serum N terminal telopeptide of type I collagen showed a tendency to decrease. Conclusion: Switching raloxifene with minodronate is effective in poor responders of osteoporosis treatment and should be considered as one of the treatment options for osteoporosis.

AB - Introduction: Intramuscular and vaginal progesterone are recommended for prevention of preterm labor (PTL) in women with risk factors. Studies are emerging to indicate that HIV-infected women on combination antiretroviral therapy (cART) are at risk of PTL and low birth weight (LBW), and may benefit from supplemental progesterone. This study aims to determine the perceived acceptability of various modes of progesterone supplementation to prevent PTL and LBW in HIV-infected and HIV-uninfected women. Methods: HIV-infected and HIV uninfected women were recruited in Lusaka, Zambia. The participants completed a questionnaire to assess their willingness to take oral, vaginal, or intramuscular progesterone supplementation for preventing PTL and LBW, preferred modes of supplementation, and concern for PTL and LBW. Results: The study questionnaire was completed by 147 participants. Of the participants, 98.6% would consider using a medication to help prevent PTL and LBW, of whom 97.9% would consider using an oral form of progesterone. In addition, 83.3% and 84.0% of women would consider intramuscular and vaginal (gel or tablet) administration of progesterone respectively. Between intramuscular and vaginal modes of progesterone, 60.5% of participants (n=147) preferred intramuscular progesterone, while 39.5% preferred vaginal progesterone. There was no difference in preference between HIV-infected (n=70) and HIV-uninfected (n=77) women. Conclusions/implications: Pregnant Zambian women demonstrated a high degree of acceptance for all modes of progesterone supplementation for the prevention of PTL and LBW. Women preferred intramuscular over vaginal supplementation. Progesterone supplementation can be considered a feasible intervention for preventing PTL and LBW in both HIV infected and HIV-uninfected pregnant Zambian women.

AB - Acne vulgaris is the most common skin disease. It affects the young adult female population and generates great impact on physical and mental health. One of the treatments with good results for affected women is combined oral contraceptive pills (COCPs). The aim of this study was to determine the clinical effect of facial acne management with ethinylestradiol 20 ug/dienogest 2 mg in a cohort of Colombian adult women. A cohort of 120 female university students was followed for 12 months. These participants were enrolled in the Sexual and Reproductive Health Program of the Santiago de Cali University. This cohort admitted women between 18 and 30 years old who had chosen to start birth control with ethinylestradiol 20 ug/dienogest 2 mg COCPs, did not have contraindi cations to the use of COCPs, and had been diagnosed with acne. Monthly monitoring of facial acne lesion count was performed. Relative changes in facial lesion count were identified. At the end of follow-up, the percentage of reduction of lesions was 94% and 23% of women had a 100% reduction in acne lesions. In conclusion, the continued use of the ethinylestradiol 20 ug/dienogest 2 mg COCPs reduced inflammatory and non-inflammatory acne lesions in reproductive-age women between 18 and 30 years of age with no severe acne. PMID- 29180908 TI - Chronic low-grade postoperative endophthalmitis in a child with Marfan syndrome. AB - This case report describes a 9-year-old male who presented to the emergency department with 2 days' history of left painful red eye. On initial examination, his outside medical records indicated that he had bilateral subluxated lenses and had undergone left eye lensectomy with glued intrascleral fixation of an intraocular lens 8 weeks earlier. Vision in left eye was poor from first postoperative day but with no undue pain or redness, and poor vision was attributed to possible vitreous bleed. Subsequent postoperative course was uneventful. He was discharged from ophthalmic care on topical steroids and antibiotic drops, one week postsurgery. The eye was healing well until he developed pain, for which ophthalmic care was sought. He underwent anterior chamber tap with intravitreal injections. Aqueous samples were positive for Staphylococcus aureus DNA by polymerase chain reaction. Post vitrectomy and implant removal, his recovery was good and vision improved to 0.50 LogMar with aphakic correction. PMID- 29180909 TI - Wearable cardioverter defibrillators for the prevention of sudden cardiac arrest: a health technology assessment and patient focus group study. AB - Aim: To summarize the evidence on clinical effectiveness and safety of wearable cardioverter defibrillator (WCD) therapy for primary and secondary prevention of sudden cardiac arrest in patients at risk. Methods: We performed a systematic literature search in databases including MEDLINE via OVID, Embase, the Cochrane Library, and CRD (DARE, NHS-EED, HTA). The evidence obtained was summarized according to GRADE methodology. A health technology assessment (HTA) was conducted using the HTA Core Model(r) for rapid relative effectiveness assessment. Primary outcomes for the clinical effectiveness domain were all-cause and disease-specific mortality. Outcomes for the safety domain were adverse events (AEs) and serious adverse events (SAEs). A focus group with cardiac disease patients was conducted to evaluate ethical, organizational, patient, social, and legal aspects of the WCD use. Results: No randomized- or non randomized controlled trials were identified. Non-comparative studies (n=5) reported AEs including skin rash/itching (6%), false alarms (14%), and palpitations/light-headedness/fainting (9%) and discontinuation due to comfort/lifestyle issues (16-22%), and SAEs including inappropriate shocks (0 2%), unsuccessful shocks (0-0.7%), and death (0-0.3%). The focus group results reported that experiencing a sense of security is crucial to patients and that the WCD is not considered an option for weeks or even months due to expected restrictions in living a "normal" life. Conclusion: The WCD appears to be relatively safe for short-to-medium term, but the quality of existing evidence is very low. AEs and SAEs need to be more appropriately reported in order to further evaluate the safety of the device. High-quality comparative evidence and well described disease groups are required to assess the effectiveness of the WCD and to determine which patient groups may benefit most from the intervention. PMID- 29180910 TI - Research during medical school: is it particularly difficult in developing countries compared to developed countries? AB - Objectives: Medical student involvement in research has been declining over the years. We reviewed the factors that hinder participation in research with a focus on developing countries. Methods: Literature search was performed using PubMed, MEDLINE and Cochrane Library. Peer-reviewed articles published between 1995 and 2017 were screened for relevance to identify key factors affecting medical student involvement in research with a particular focus on developing world. Analytical review is presented here in this article in relation to commonly reported aspects related to research during medical school. Results: This search revealed varied contributing factors that hinder students' growth and interest in research. It commonly highlighted few aspects in relation to research during medical school, and they were "variability in research uptake among students and issues related to them, their knowledge and attitude toward research and organizational input and its influence on students". Conclusion: While early introduction to research by inculcating a mindset aimed at research has been proposed, it has not been seen in practice during either the medical school or beyond to an extent that was expected. It appears that developing countries, while they share some of the reasons with developed countries, have their own set of difficulties, which are influenced by culture, beliefs and priorities. PMID- 29180911 TI - Burning Mouth Syndrome: Aetiopathogenesis and Principles of Management. AB - Burning mouth syndrome (BMS) is a chronic debilitating oral condition characterised by a burning sensation of the oral mucosa in an otherwise apparently normal person. Its aetiology and pathogenesis are obscure, but both psychogenic factors and peripheral and central neuropathies appear to be implicated. There is no cure for BMS, and treatment with either local or systemic medications focuses on the relief of symptoms and on improving quality of life. In recalcitrant cases, psychological/psychiatric intervention may be helpful. In order to improve treatment outcomes, a better understanding of the pathogenesis of this syndrome might provide a basis for the development of more effective management strategies. In this short review, we discuss current knowledge of the diagnosis, aetiopathogenesis, and management of BMS. PMID- 29180912 TI - Dealing with the positive publication bias: Why you should really publish your negative results. AB - Studies with positive results are greatly more represented in literature than studies with negative results, producing so-called publication bias. This review aims to discuss occurring problems around negative results and to emphasize the importance of reporting negative results. Underreporting of negative results introduces bias into meta-analysis, which consequently misinforms researchers, doctors and policymakers. More resources are potentially wasted on already disputed research that remains unpublished and therefore unavailable to the scientific community. Ethical obligations need to be considered when reporting results of studies on human subjects as people have exposed themselves to risk with the assurance that the study is performed to benefit others. Some studies disprove the common conception that journal editors preferably publish positive findings, which are considered as more citable. Therefore, all stakeholders, but especially researchers, need to be conscious of disseminating negative and positive findings alike. PMID- 29180913 TI - Minimum requirements for the estimation of measurement uncertainty: Recommendations of the joint Working group for uncertainty of measurement of the CSMBLM and CCMB. AB - The International vocabulary of metrology - Basic and general concepts and associated terms (VIM3, 2.26 measurement uncertainty, JCGM 200:2012) defines uncertainty of measurement as a non-negative parameter characterizing the dispersion of the quantity values being attributed to a measurand, based on the information obtained from performing the measurement. Clinical Laboratory Standards Institute (CLSI) has published a very detailed guideline with a description of sources contributing to measurement uncertainty as well as different approaches for the calculation (Expression of measurement uncertainty in laboratory medicine; Approved Guideline, CLSI C51-A 2012). Many other national and international recommendations and original scientific papers about measurement uncertainty estimation have been published. In Croatia, the estimation of measurement uncertainty is obligatory for accredited medical laboratories. However, since national recommendations are currently not available, each of these laboratories uses a different approach in measurement uncertainty estimation. The main purpose of this document is to describe the minimal requirements for measurement uncertainty estimation. In such way, it will contribute to the harmonization of measurement uncertainty estimation, evaluation and reporting across laboratories in Croatia. This recommendation is issued by the joint Working group for uncertainty of measurement of the Croatian Society for Medical Biochemistry and Laboratory Medicine and Croatian Chamber of Medical Biochemists. The document is based mainly on the recommendations of Australasian Association of Clinical Biochemists (AACB) Uncertainty of Measurement Working Group and is intended for all medical biochemistry laboratories in Croatia. PMID- 29180916 TI - Measurement uncertainty of blood ethanol concentration in drink-driving cases in an emergency laboratory. AB - Introduction: The quality of blood ethanol concentration (BEC) determination is important because of its legal ramifications. Measurement uncertainty provides quantitative information about the quality and reliability of test results. In this study, we aim to calculate the measurement uncertainty for the ethanol test in our laboratory measured with a Synchron Systems Ethanol assay kit by employing an enzymatic rate method on the Beckman-Coulter Olympus AU400 auto analyzer (Beckman Coulter Inc, Melville, USA). Materials and methods: The measurement uncertainty values were calculated in accordance to the Nordtest guidelines. All vehicle drivers involved in a traffic accident were retrospectively inspected for the BEC test conducted during July to December 2016 in our emergency laboratory. Results: A 1034 vehicle drivers had their BEC tested. The results for 181 drivers were > 0.50 g/L and reported as positive. The serum ethanol concentration in those showing a positive result was 2.04 +/- 1.01 g/L, over four times the legal limit. The median BEC in those showing a negative result was 0.03 (IQR: 0.03) g/L. The expanded uncertainty obtained was 19.74%. When measurement uncertainty values were added to the results of the 1034 drivers who were retrospectively screened, eight vehicle drivers had results with 95% confidence intervals that exceeded the legal limit 0.50 g/L. Conclusions: The BEC test results for vehicle drivers with values close to legal limits should be reported as the obtained ethanol concentration with corresponding measurement uncertainty. PMID- 29180915 TI - National survey on current situation of critical value reporting in 973 laboratories in China. AB - Introduction: The aim of the study was to investigate the state-of-the-art of the performance of critical value reporting and provide recommendations for laboratories setting critical value reporting time frames. Materials and methods: The National Centre for Clinical Laboratories in China initiated a critical value reporting investigation in 2015. A questionnaire related to critical value reporting policy was sent to 1589 clinical laboratories in China online. The questionnaire consisted of a set of questions related to critical value reporting policy and a set of questions related to timeliness of critical value reporting. The survey data were collected between March and April 2015. Results: A total survey response rate was 61.2%. The critical value unreported rate, unreported timely rate, and clinical unacknowledged rate of more than half of participants were all 0.0%. More than 75.0% of participants could report half of critical values to clinicians within 20 minutes and could report 90.0% of critical values to clinicians within 25 minutes (from result validation to result communication to the clinician). The median of target critical value reporting time was 15 minutes. "Reporting omission caused by laboratory staff", "communications equipment failure to connect", and "uncompleted application form without contact information of clinician" were the three major reasons for unreported critical value. Conclusions: The majority of laboratories can report critical values to responsible clinical staff within 25 minutes. Thus, this value could be recommended as suitable critical value reporting time frame for biochemistry laboratories in China. However, careful monitoring of the complete reporting process and improvement of information systems should ensure further improvement of critical value reporting timeliness. PMID- 29180914 TI - Insights into cerumen and application in diagnostics: past, present and future prospective. AB - Cerumen or earwax is an emerging bio-fluid in clinical diagnosis that has been very little exploited during the past decades in spite of its high diagnostic potential. It is highly abundant in diagnostic biomarkers such as genetic material, lipids, proteins, chemical elements, internal and external metabolites (e.g. hormones, volatile organic compounds, amino acids, xenobiotics etc.) reaching earwax from the blood circulation. Thus, it is able to reflect not only physiology, pathophysiology of the human body but can also detect recent and long term exposure to environmental pollutants, without the need of invasive blood tests and in the same time overcoming many disadvantages faced by using other diagnostic biological fluids. This review discusses the biology, functions, chemistry of earwax, past and current approaches for the study of its chemical composition, emphasizing how a detected variation in its composition can offer information of high clinical value, which can be useful in diagnosis of many diseases such as metabolic disorders and tumours as well as in forensic applications. It also presents details about techniques of sample collection, storage, and analysis. Moreover, it highlights concerns about the use of earwax for diagnostic purposes, which should be addressed to make earwax diagnostics a reality in the future. PMID- 29180917 TI - Establishing the upper reference limit of Galectin-3 in healthy blood donors. AB - Introduction: Galectin-3 (Gal-3) is an independent predictor of poor outcomes and mortality in patients with heart failure (HF). Thus, it has been proposed as a reliable prognostic biomarker for HF. The definition of reference intervals is mandatory for interpreting the findings of experimental studies and encouraging the routine use of biomarkers in clinical practice. To date, no study assessed the reference intervals of Gal-3 and identified the biological variables that affect its concentration in a well-defined healthy population. The aim of this study was to determine the upper reference limit (URL) of Gal-3 in a highly reliable population of healthy subjects. Materials and methods: We recruited 714 blood donors. After measuring surrogate biomarkers to identify underlying diseases, 8 subjects were excluded. A final population of 706 individuals (385 men (54.5%); median age 39 (18-65) years) was included. The URL was calculated using the non-parametric percentile approach. Results: The 97.5th percentile URL of plasma Gal-3 in our study population (90% CI) was 26.1 (23.3-31.5) ng/mL. After stratifying subjects according to age, the URL of Gal-3 was found to be considerably higher in older (> 45 years) than in younger subjects (31.5 (26.2 51.4) vs 21.8 (21-26.1) ng/mL, respectively). No sex-related differences were found in Gal-3 plasma concentration. Conclusions: We established the URL of Gal-3 in a highly selected healthy population. Our findings indicate that age is an important determinant of Gal-3 plasma concentration, so that multiple diagnostic cut-offs should be preferably used according to the different age classes. PMID- 29180918 TI - Analytical evaluation of a fully automated immunoassay for faecal calprotectin in a paediatric setting. AB - Introduction: Faecal calprotectin (FC) is a routinely used marker for identifying and monitoring children with inflammatory bowel disease (IBD). This non-invasive test is useful for screening children with gastrointestinal symptoms to avoid unnecessary invasive procedures. In this study, we validated for the first time the performance of a fully automated particle-enhanced turbidimetric immunoassay (PETIA) on the VITROS(r) 5600 analyzer for measurement of FC in symptomatic children and adolescents. Materials and methods: For performance validation of the PETIA (fCAL(r) turbo, Buhlmann Laboratories, Switzerland) on the VITROS(r) 5600 analyzer (Ortho Clinical Diagnostics, USA) limit of quantitation (LoQ), linearity, precision data and calibration curve stability were defined. Additionally, 95 faecal samples were measured using the PETIA, an enzyme-linked immunosorbent assay (ELISA; fCAL(r), Buhlmann Laboratories, Switzerland) and a semi-quantitative lateral flow assay (Quantum Blue Reader(r), Buhlmann Laboratories, Switzerland) for agreement evaluation. Results: The LoQ for calprotectin using PETIA on the VITROS(r) 5600 analyzer was 21 ug/g. The linearity range was 20 - 2100 ug/g and the precision study showed a total coefficient of variation (CV) between 2.3% and 8.9%. The calibration curve was stable for 4 weeks. Using the clinical samples quantifiable by PETIA, ELISA and the semi-quantitative lateral flow assay, Passing-Bablok regression analysis and Bland-Altman plots showed good agreement. Conclusions: Due to good performance characteristics and agreement with established methods, the fully automated PETIA on the routine chemistry analyzer VITROS(r) 5600 is a new analytical option for the rapid determination of FC. PMID- 29180919 TI - False positive immunoassay for heparin-induced thrombocytopenia in the presence of monoclonal gammopathy: a case report. AB - Heparin induced thrombocytopenia (HIT) is a life-threatening disorder which diagnosis depends on laboratory evaluation. The objective of this report is to present the impact of different laboratory methods for HIT detection on the diagnostic evaluation process. In this case, a 78-year old female patient previously diagnosed with monoclonal gammopathy of undetermined significance (MGUS) was administered with heparin for pulmonary embolism treatment. Patient's initial diagnostic work-up (determination of platelet count and prothrombin time measurement for monitoring of pharmacotherapy) was followed by the clinical estimation of HIT likelihood by "4Ts" score, two immunoassays (ID-PaGIA Heparin/PF4 Antibody Test and ELISA PF4 IgG assay) and one functional test called high-performance liquid chromatography serotonin release assay (HPLC-SRA). The result of "4Ts" score indicated a low likelihood of HIT but persistent thrombocytopenia that appeared days after discontinuation of heparin therapy suggested delayed-onset HIT. Both immunoassays were positive for presence of HIT autoantibodies, while the functional HPLC-SRA was negative. Since different methods gave opposing results, their interpretation required great attention. In comparison to the HPLC-SRA, immunoassays are prone to the analytical interferences associated with the presence of non-specific antibodies, which may lead to false positive results. In this case, where the patient is known to produce antibodies of undetermined significance, HIT was ruled out as the possible cause of persistent thrombocytopenia primarily due to the negative result of HPLC-SRA, which is not prone to this type of interferences, but also due to the low "4Ts" clinical score. PMID- 29180920 TI - Urinary free cortisol assessment by liquid chromatography tandem mass spectrometry: a case study of ion suppression due to unacquainted administration of piperacillin. AB - Introduction: Liquid chromatography coupled to atmospheric pressure ionization tandem mass spectrometry (LC-ESI-MS/MS) is currently considered the reference method for quantitative determination of urinary free cortisol (UFC). One of the major drawbacks of this measurement is a particular form of matrix effect, conventionally known as ion suppression. Materials and methods: We describe here the case of a 66-year-old-patient referred to the daily service of general medicine for intravenous antibiotic administration due to a generalized Staphylococcus aureus infection and for routine 24 hours UFC monitoring in the setting of glucocorticoid replacement therapy. Results: The observation of 10 fold decrease of internal standard of cortisol signal led us to hypothesize the presence of an ion suppression effect due to a co-eluting endogenous compound. Screening analysis of tandem mass spectrometry (MS/MS) spectra of the interfering molecule, along with in vitro confirmation analyses, were suggestive of the presence of high concentration of piperacillin. The problem was then easily solved with minor modifications of the chromatographic technique. Conclusions: According to our findings, antibiotic therapy with piperacillin/tazobactam should be regarded as an important interference in UFC assessment, which may potentially affect detection capability, precision and accuracy of this measurement. This case report emphasizes that accurate anamnesis and standardization of all phases of urine collection are essential aspects for preventing potential interference in laboratory testing.

PMID- 29180925 TI - Marjolin's ulcer in chronic wounds - review of available literature. AB - Marjolin's ulcer is a rare, aggressive skin cancer developing in scar tissue, chronic ulcers and areas affected by inflammations. Its incidence is estimated to range from 1% to 2% of all burn scars. It most frequently takes the form of squamous cell carcinoma which sometimes is diagnosed during examination of lesions developing in scars and hard-to-heal chronic wounds (pressure sores, leg ulcers). Therapeutic management of Marjolin's ulcer requires well-designed treatment plan to ensure optimal medical care and good quality of life for the patient. The high risk of metastases and damage to the structure of vitally important organs determines the need for early diagnosis and prompt surgical intervention with supplementary therapy. The purpose of the study was to examine etiopathogenesis of Marjolin's ulcer and principles of its treatment. The authors focused on the aspect of malignant degeneration in chronic wounds (leg ulcers, pressure sores) as a very rare, aggressive form of Marjolin's ulcer. A review of the available literature on the issue of Marjolin ulcers was conducted using the key words; Marjolin ulcers, pressure sore, chronic wound. Malignant degeneration in chronic wounds is a very rare aggressive form of Marjolin ulcer. Increased oncological alertness should be displayed by nursing and medical personnel taking care of patients with chronic wounds. PMID- 29180926 TI - Radiotherapy in testicular germ cell tumours - a literature review. AB - Testicular germ cell tumours (GCT) represent about 1-2% of malignant in men. The essential therapeutic option for early-stage GCT is radical orchiectomy (RO), except in situations that require immediate chemotherapy in patients with a massive dissemination and unequivocally elevated levels of tumour markers. Postoperative radiotherapy (PORT) in patients with testicular seminoma in Clinical Stage I (CS I) is one of the treatment options next to active surveillance (AS) and chemotherapy (CHTH). Regardless of the procedure, five-year survival in this group of patients ranges between 97% and 100%. In the article, we present the literature review pertinent to therapeutic options, with a focus on radiotherapy. We have searched MEDLINE (PubMed) for all studies on patients with GCT treated with radiation therapy during the last 20 years, and the current therapeutic recommendations. We used the following keywords: germ cell tumours, testis, seminoma, non-seminoma, radiotherapy, outcome. PMID- 29180927 TI - Comparative efficacy of epigallocatechin-3-gallate against H2O2-induced ROS in cervical cancer biopsies and HeLa cell lines. AB - Aim of the study: Antioxidants play an important role in maintaining physiological homeostasis. Recent literature emphasises the potential therapeutic effects of natural antioxidants that play anti-inflammatory and antioxidant effects applicable in preventing oxidative stress-induced injury, which characterises their pathogenesis. The goal of this study was to evaluate the protective role of EGCG on the HeLa cell line and cancerous cells. Material and methods: The HeLa cell line and cervical cancer biopsies (CCB) were treated with varying doses of antioxidants to determine their effects. Thereafter, hydrogen peroxide (0-10 nM) - an ROS-generating compound - was co-cultured with varying doses of epigallocatechin-3-gallate (EGCG). The effect of this compound on superoxide dismutase (SOD) and glutathione peroxidase (GPx) activity was assessed. Result: The activity of SOD and GPx was protected significantly in the treatment of EGCG in cervical cancer biopsies and HeLa cell line. Hypothesis: It is hypothesised that EGCG has free radical scavenging properties. Conclusions: EGCG protected the activity SOD and GPx equally in cervical cancer biopsies (CCB) and HeLa cell line. PMID- 29180928 TI - The importance of serum and pleural fluid level of vascular endothelial growth factor (VEGF) and VEGF fluid/serum ratio in the differential diagnosis of malignant mesothelioma-related pleural effusion. AB - Aim of the study: Vascular endothelial growth factor (VEGF) is one of the parameters that has been studied in differential diagnosis of malignant fluids. This study is aimed at evaluate applicability of serum, fluid VEGF level and fluid to serum VEGF ratio in the diagnosis of malignant pleural mesothelioma (MPM). Material and methods: The patients with pleural effusion over age of 18, between 2011 and 2015 were included in the study. They were divided into three groups: group 1 - mesothelioma patients; group 2 - other malignancies; and group 3 - benign aetiologies. Group 1 and 2 were termed as the malignant group. Fluid, serum VEGF levels, and the ratio of fluid/serum VEGF level were studied to evaluate the fluid/serum VEGF ratio in all groups. Results: Twenty cases with mesothelioma, 44 cases with other malignancies, and 20 cases with benign aetiologies were included in this study. No statistically significant difference was found according to serum VEGF levels for all groups, (group 1: 437 +/-324 pg/ml, group 2: 354 +/-223 pg/ml, group 3: 373 +/-217 pg/ml, p = 0.836), while fluid VEGF levels showed a statistically significant difference (group 1: 3359 +/ 700 pg/ml, group 2: 2175 +/-435 pg/ml, group 3: 1092 +/-435 pg/ml, p = 0.041). The ratio of fluid to serum VEGF levels showed a difference, at the significance limit, between the malignant (group 1 and group 2) and benign (group 3) groups (8.83 +/-1.29 vs. 4.57 +/-1.07, p = 0.059) but showed a statistically significant difference between the mesothelioma and benign groups (12.11 +/-1.68 vs. 4.57 +/ 1.07, p = 0.044). Conclusions: The VEGF fluid/serum ratio may be an applicable parameter in the differential diagnosis of malignant fluids, especially MPM.

AB - Aim of the study: The present study aims to estimate the prevalence and distribution of HPV genotypes and identify related risk factors among Turkish women. Material and methods: 11 624 Turkish women attending our gynaecological clinic and expressing a desire for access to cervical cancer screening were assessed during the years 2014-2016. Cervical specimens were collected and transported using the HC2 HPV DNA Collection Device (consisting of a cervical brush and digene Specimen Transport Medium). Results: Among these 11 624 individuals, positive HPV test results were obtained for 325 (2.79%), and negative results were observed for 11 299 (97.2%). The vast majority of patients were between the 3rd and 5th decades and the mean age of the patients was 44 +/ 9.12 (range 27-66). Among the HPV-positive women, 205 were positive for a single HPV type (205/325 = 63.1% of HPV infections; 205/11624 = 1.76% of all samples) and 120 were positive for multiple types (120/325 = 36.9% of HPV infections; 120/11624 = 1.03% of all samples). The four most prevalent high-risk types were HPV 16, 31, 51 and 52, with frequencies of 11.25%, 7.83%, 6.06% and 3.16%, respectively. Conclusions: There appears to be geographic variation in the distribution of HPV genotypes. In this study, the four most prevalent high-risk types were HPV 16, 31, 51 and 52, with frequencies of 11.25%, 7.83%, 6.06% and 3.16%, respectively. PMID- 29180930 TI - Examination of anastomotic leak with aqueous contrast swallow after total gastrectomy: Should it be carried out routinely? AB - Aim of the study: Examination of esophagojejunal (EJ) anastomosis with aqueous contrast swallow after total gastrectomy is still routinely conducted by many centres. The present study aimed to answer the question: Is it necessary to evaluate EJ anastomosis in terms of leakage by having every patient drink oral contrast agent before initiation of oral food intake after total gastrectomy (TG) performed due to gastric cancer? Material and methods: Clinical and radiological results of patients on whom total gastrectomy was performed due to gastric cancer between January 2013 and December 2016 were retrospectively reviewed. Diagnostic method used for patients in whom leak developed and therapeutic interventions were assessed. Evaluation results from aqueous contrast agent and clinical, laboratory, and tomographic findings were studied. Results: Sixty of the 69 patients who underwent total gastrectomy with a diagnosis of gastric adenocarcinoma swallowed aqueous contrast agent on postoperative day 7 +/-2 days and were evaluated in terms of anastomotic leak. Leak developed in 14 patients (20.2 %), 10 of whom ingested contrast agent. Leak was identified in 6 of those patients; however, diagnosis was made with multislice computed tomography (CT) in four patients (40%). The sensitivity of the examination with aqueous contrast agent was 60%. Conclusions: Evaluating anastomotic leak with aqueous contrast agent after TG has low sensitivity, and it would be wise to resort to this procedure in cases with clinical suspicion, rather than routinely performing it in every patient.

AB - Aim of the study: Primary bone tumours are relatively rare, but their diagnosis and treatment is difficult and connected with a high risk of complications. The goal of this report is a retrospective evaluation of outcomes in patients with primary tumours of the humerus treated in our centre with the use of modular endoprosthetic reconstruction. Material and methods: Currently, surgical treatment is a standard procedure for local therapy, with wide tumour-free margin resection after a planned multidisciplinary and individualised strategy of tumour management based on the diagnostic biopsy result. The best option for patients to avoid disability is simultaneous surgical reconstruction aiming to spare the limb and its functionality. Results: In this report, we present the results of treatment of our 11 adult patients suffering from primary bone tumours of the humerus, who have undergone wide bone resection followed by reconstruction with the use of a modular MUTARS(r) endoprosthesis. Conclusions: The study showed that prosthetic reconstruction of the resected humerus due to a primary bone tumour is safe and acceptable for patients; despite the fact that limitation of active abduction of the shoulder is up to 20 grades, this surgical procedure provides satisfactory limb function. PMID- 29180932 TI - Assessment of the accuracy of dose calculation in the build-up region of the tangential field of the breast for a radiotherapy treatment planning system. AB - Aim of the study: Our objective was to quantify the accuracy of dose calculation in the build-up region of the tangential field of the breast for a TiGRT treatment planning system (TPS). Material and methods: Thermoluminescent dosimeter (TLD) chips were arranged in a RANDO phantom for the dose measurement. TiGRT TPS was also used for the dose calculation. Finally, confidence limit values were obtained to quantify the accuracy of the dose calculation of the TPS at the build-up region. Results: In the open field, for gantry angles of 15 degrees , 30 degrees , and 60 degrees , the confidence limit values were 17.68, 19.97, and 34.62 at a depth of 5 mm, and 24.01, 19.07, and 15.74 at a depth of 15 mm, respectively. In the wedge field, for gantry angles of 15 degrees , 30 degrees , and 60 degrees , the confidence limit values were 21.64, 26.80, and 34.87 at a depth of 5 mm, and 27.92, 22.04, and 20.03 at a depth of 15 mm, respectively. Additionally, the findings showed that at a depth of 5 mm, the confidence limit values increased with increasing gantry angle while at a depth of 15 mm, the confidence limit values decreased with increasing gantry angle. Conclusions: Overall, TiGRT TPS overestimated doses compared to TLD measurements, and the confidence limit values were greater for the wedge field than for the open fields. Our findings suggest that the assessment of dose distributions in large-dose gradient regions (i.e. build-up region) should not entirely rely on TPS calculations. PMID- 29180933 TI - Implementation of an enhanced recovery after surgery (ERAS) protocol in a gynaecology department - the follow-up at 1 year. AB - Aim of the study: An ERAS protocol provides the latest perioperative care principles, whose primary aim is to reduce complication rates, and therefore mortality. The aim of this study is to establish the progress of the ERAS pathway implementation in our gynaecology department. Material and methods: This was a retrospective analysis of two sets of 100 consecutive medical records: patients treated before (PRE-ERAS) and after (ERAS) introduction of the ERAS protocol. All patients were comparable and all underwent major gynaecological surgery. Patients as well as medical and nursing staff were informed about the proposed preparation, surgical management and postoperative routine. Results and conclusions: Patients were given supper and drank water during the night. Laparoscopic surgery was used in 44% and spinal anaesthesia was given for open surgery in 43 study patients. Use of drains was reduced only by 23%, bowel preparation by 15%. Intravenous fluid administration was reduced by 22%. Use of postoperative morphine was minimised to 12 patients. Postoperative nausea was managed with the regular use of anti-emetics. Anti-coagulation was given to 80% of the study group. Difficulties in the introduction of the ERAS protocol were due to refusal by some patients to mobilise and eat early postoperatively. Patients in the ERAS programme group were discharged earlier.Further information about the ERAS protocol in the media would facilitate patients' education among conservative society. In order to introduce new and innovative treatment methods, one has to take into account the cultural and ideological factors, especially when patient involvement is essential.

AB - Introduction: Treatment of unresectable liver metastases (LM) from uveal melanoma (UM) remains a major clinical challenge. Systemic chemotherapy and chemoimmunotherapy regimens extrapolated from cutaneous melanoma are considered to be ineffective in therapy of metastases from uveal melanoma. Studies suggest that the progression of hepatic metastases rather than the primary tumor or metastases in other organs determines survival. Case report: We report a case of transarterial chemoembolization of 57-year-old man diagnosed with unresectable liver metastases from uveal melanoma with irinotecan eluting beads. Therapy resulted in long progression free survival and overall survival, 41 months and 45 months after diagnosis of metastatic disease respectively. Patient did not experience any major side effects of the therapy. Follow-up CTs indicate stable disease in mRECIST criteria and partial response in CHOI criteria. Conclusions: Transarterial chemoembolization with drug eluting beads loaded with irinotecan may be an effective treatment of unresectable liver metastases from uveal melanoma.

AB - Medulloblastoma (MB) is a highly aggressive soft tissue neoplasm, classified as a primitive neuroectodermal tumor. It is the most common posterior fossa tumor in children, but occurs rarely in adults. MB accounts for approximately 20% of all primary central nervous system (CNS) tumors of childhood, while its incidence is around 1% of adult brain tumors. Most often it occurs in the cerebellum. We report a case of multicentric MB involving the bilateral cerebellopontine angle (CPA) and right cerebellar hemisphere. The tumor showed isointensity on T1/T2 weighted images, and slight hyperintensity on T2-weighted fluid-attenuated inversion-recovery (FLAIR) images. The MB had restricted diffusion on diffusion weighted images (DWI). It was not easy to make an accurate diagnosis before biopsy. The lesion in our patient presented with atypical MR image features of medulloblastoma. To our knowledge, this is the first case of bilateral CPA MB. PMID- 29180936 TI - Osimertinib - effective treatment of NSCLC with activating EGFR mutations after progression on EGFR tyrosine kinase inhibitors. AB - Non-small cell lung cancer (NSCLC) driven by activating mutations in epidermal growth factor receptor (EGFR) constitutes up to 10% of NSCLC cases. According to the NCCN recommendations, all patients (with the exception of smoking patients with squamous cell lung cancer) should be screened for the presence of activating EGFR mutations, i.e. deletion in exon 19 or point mutation L858R in exon 21, in order to select the group that benefits from EGFR tyrosine kinase inhibitors (EGFR TKIs) treatment. Among approved agents there are the 1st generation reversible EGFR TKIs, erlotinib and gefitinib, and the 2nd generation irreversible EGFR TKI, afatinib. The objective response rates to these drugs in randomised clinical trials were in the range of 56-74%, and median time to progression 9-13 months. The most common determinant of resistance to these drugs is the clonal expansion of cancer cells with T790M mutation (Thr790Met) in exon 20 of EGFR. Osimertinib (TagrissoTM), a 3rd generation, irreversible EGFR tyrosine kinase inhibitor, constitutes a novel, highly efficacious treatment for NSCLC patients progressing on EGFR TKIs with T790M mutation confirmed as the resistance mechanism. Resistance mutation can be determined in tissue or liquid biopsy obtained after progression on EGFR TKIs. Osimertinib has a favourable toxicity profile, with mild rash and diarrhoea being the most common. In this article, we present three cases that were successfully treated with osimertinib after progression on 1st and 2nd generation EGFR TKIs. PMID- 29180937 TI - Synthesis and Cytotoxic Evaluation of Steroidal Copper (Cu (II)) Complexes. AB - Using estrone and pregnenolone as starting materials, some steroidal copper complexes were synthesized by the condensation of steroidal ketones with thiosemicarbazide or diazanyl pyridine and then complexation of steroidal thiosemicarbazones or steroidal diazanyl pyridines with Cu (II). The complexes were characterized by IR, NMR, and HRMS. The synthesized compounds were screened for their cytotoxicity against HeLa, Bel-7404, and 293T cell lines in vitro. The results show that all steroidal copper (II) complexes display obvious antiproliferative activity against the tested cancer cells. The IC50 values of complexes 5 and 12 against Bel-7404 (human liver carcinoma) are 5.0 and 7.0 MUM.

PMID- 29180940 TI - National and transnational belonging among Turkish and Moroccan older migrants in the Netherlands: protective against loneliness? AB - This research investigates how a sense of belonging functions as protective mechanism against loneliness. Inspired by the work of Berry (1980) on acculturation strategies (i.e. integration, assimilation, separation and marginalization), we distinguish migrants who feel a relatively strong or weak sense of belonging to larger society and those who feel a strong or weak belonging to the "own group." We expect that more national belonging contributes to less loneliness. We add a transnational perspective by arguing that feelings of belonging to the own group can take place in the country of settlement, but can also be transnational, i.e. a feeling of belonging to the country of origin. Transnational belonging can protect against loneliness, as it acknowledges the importance of place attachment. Using data from the Longitudinal Aging Study Amsterdam on older migrants aged 55-66, we employ latent class analysis and find five national belonging clusters, interpretable in terms of Berry's acculturation strategies. Further analyses reveal mixed evidence: some aspects of transnational belonging vary with belonging to the own group, but other aspects point to a third dimension of belonging. Regression analysis shows that those marginalized are loneliest and that a transnational sense of belonging contributes to more loneliness. We conclude that Berry's (1980) typology is useful for interpreting older migrants' national belonging and that a transnational sense of belonging is apparent among older migrants, but needs to be explored further. PMID- 29180941 TI - Legislating for transnational ageing: a challenge to the logics of the welfare state. AB - Transnational ageing presents fundamental challenges to nationally bounded welfare states, which historically have tended to be organised according to a logic of solidarity among nationals and permanent residents of a given state territory. Nonetheless, the Dutch and French governments have taken steps to break this link between solidarity and territorially bounded consumption of welfare, by providing lifelong income security for older migrants who return to countries of origin on a permanent or semi-permanent basis. This article asks what motivated policymakers to initially develop these novel policy tools for transnational ageing which contradict the territorial logic of the welfare state. Based on interviews with key stakeholders and available official documents, we find that in both France and the Netherlands, policymakers' initial motivations can be characterised as rather benign, if not beneficent: to facilitate return for those who are willing but unable to afford it. However, two types of obstacle have impeded the delivery of such policies. Non-discrimination clauses and free movement rights in EU law may make it difficult to implement policies for specific categories of older migrants. Electoral realpolitik may also lead policymakers to shelve policies which benefit older migrants, in a European context where public opinion on immigration is less and less favourable. Nonetheless, opposition may be neutralised by the budgetary advantages of these schemes, since older returnees do not consume public services such as healthcare. PMID- 29180942 TI - The emergence of care facilities in Thailand for older German-speaking people: structural backgrounds and facility operators as transnational actors. AB - This paper presents findings from an ethnographic study of old age care facilities for German-speaking people in Thailand. It analyses the conditions and processes behind the development and specific designs of such facilities. It first looks at the intertwinement, at the socio-structural level, of different transborder developments in which the facilities' emergence is embedded. Second, it analyses the processes that accompany the emergence, development and organisation of these facilities at the local level. In this regard, it points out the central role of the facility operators as transnational actors who mediate between different frames of reference and groups of actors involved in these facilities. It concludes that the processes of mediation and intertwining are an important and distinctive feature of the emergence of these facilities, necessitated by the fact that, although the facilities are located in Thailand, their 'markets' are in the German-speaking countries of their target groups. PMID- 29180943 TI - Transnational grandparenting in the digital age: mediated co-presence and childcare in the case of Romanian migrants in Switzerland and Canada. AB - Taking transnational families of Romanian migrants in Canada and Switzerland as a case in point, this paper accounts for the emergence of new patterns of "grandparenting" and "doing family" practices in the digital age, based on ICTs mediated co-presence. It shows that migrants' parents are able to acquire manifold technological skills in order to cope with distance and separation and to improve the quality of their interaction and relationships with children and grandchildren living abroad. Ordinary co-presence routines within polymedia environments allow grandparents to take on their role as childcare providers across borders and develop new transnational lifestyles. Thus, despite contrasting feelings of well-being and distress that mediated co-presence generates, migrants' parents are able to place themselves as key actors within the transnational family in the digital society and invent new grandparenting practices. PMID- 29180944 TI - Presenteeism, stress resilience, and physical activity in older manual workers: a person-centred analysis. AB - This study used a person-centred approach to explore typologies of older manual workers based on presenteeism, stress resilience, and physical activity. Older manual workers (n = 217; 69.1% male; age range 50-77; M age = 57.11 years; SD = 5.62) from a range of UK-based organisations, representing different manual job roles, took part in the study. A cross-sectional survey design was used. Based on the three input variables: presenteeism, stress resilience and physical activity, four distinct profiles were identified on using Latent Profile Analysis. One group ('High sport/exercise and well-functioning'; 5.50%) engaged in high levels of sport/exercise and exhibited low levels of stress resilience and all types of presenteeism. Another profile ('Physically burdened'; 9.70%) reported high levels of work and leisure-time physical activity, low stress resilience, as well as high levels of presenteeism due to physical and time demands. A 'Moderately active and functioning' group (46.50%) exhibited moderate levels on all variables. Finally, the fourth profile ('Moderately active with high presenteeism'; 38.20%) reported engaging in moderate levels of physical activity and had relatively high levels of stress resilience, yet also high levels of presenteeism. The profiles differed on work affect and health perceptions largely in the expected directions. There were no differences between the profiles in socio-demographics. These results highlight complex within-person interactions between presenteeism, stress resilience, and physical activity in older manual workers. The identification of profiles of older manual workers who are at risk of poor health and functioning may inform targeted interventions to help retain them in the workforce for longer. PMID- 29180945 TI - Career histories as determinants of gendered retirement timing in the Danish and Swedish pension systems. AB - After reforms in pension systems had taken place in most European countries within the last two decades, the concern was raised that women may be disadvantaged by these reforms. It is suggested that they are faced with a higher financial need to work longer. Retrospective data from SHARELIFE are used to run an event history analysis on the timing of the final employment exit, separately for gender, country and exit cohort. This study aims to disentangle the influence of gendered labour markets and pension regulations on retirement timing by investigating conditions in Denmark and Sweden. Some evidence was found that women compensate for lower labour market attachment due to long part-time periods by working longer, especially in younger cohorts. This seems to depend on the pension system. In countries with broad basic pensions, high replacement rates for low-income groups and fewer penalties for early retirement, the compensation is suggested to be less frequent. This study indicates the growing importance of the "compensation hypothesis" compared to the "status maintenance hypothesis" of previous careers in relation with retirement timing. PMID- 29180946 TI - Educational inequalities in late-life depression across Europe: results from the generations and gender survey. AB - This study explores country- and gender-stratified educational differences in depression among older adults from 10 European countries. We examine inequalities in both absolute (prevalence differences) and relative (odds ratios) terms and in bivariate and multivariate models. We use cross-sectional, nationally representative data from the generations and gender survey. The analysis comprises 27,331 Europeans aged 60-80. Depression is measured with a seven-item version of the Center for Epidemiologic Studies Depression scale. Findings show considerable between-country heterogeneity in late-life depression. An East-West gradient is evident, with rates of depression up to three times higher in Eastern European than in Scandinavian countries. Rates are about twice as high among women than men in all countries. Findings reveal marked absolute educational gaps in depression in all countries, yet the gaps are larger in weaker welfare states. This pattern is less pronounced for the relative inequalities, especially for women. Some countries observe similar relative inequalities but vastly different absolute inequalities. We argue that the absolute differences are more important for social policy development and evaluation. Educational gradients in depression are strongly mediated by individual-level health and financial variables. Socioeconomic variation in late-life depression is greater in countries with poorer economic development and welfare programs. PMID- 29180948 TI - Validity of the de Jong Gierveld Loneliness Scale in Spanish older population: competitive structural models and item response theory. AB - Loneliness is a subjective measure of one's state of mind and the negative feelings about one's level of social contact, which usually involves an unwanted discrepancy between existing and desired relationships. It is measured through self-reported questionnaires, among which a widely used one is the de Jong Gierveld Loneliness Scale (DJGLS). Although it has been previously tested and proven to be a reliable tool for measuring loneliness of Spanish older people, some relevant research questions remain unsolved. Therefore, this article aims to present a validity study of the Spanish version of the DJGLS for its use with older people, by establishing its factorial validity; studying the adequateness of a Rasch model underlying participants' responses; offering evidence of its reliability; and testing for convergent and discriminant validity. Data were obtained in a survey conducted with older adults attending Lifelong Learning programs in Valencia (Spain). The sample consisted of 335 people aged 55 years or older. Sociodemographic data were collected, and loneliness was measured with the DJGLS and the UCLA Loneliness Scale. Results have supported a unidimensional substantive structure, but with minor method effects associated with negatively worded items. In terms of multidimensional IRT analysis, the 2 Parameters Logistic Model fitted the data well and offered better information functions than the Rasch model. Reliability and criterion-related validity estimates were adequate. PMID- 29180947 TI - Prevalence and related factors of successful aging among Chinese rural elders living in nursing homes. AB - Few studies focus on the prevalence and related factors of successful aging (SA) among Chinese rural elders living in nursing homes. This study aims to make an operational definition of successful aging, estimate the prevalence of SA, and identify factors related to SA among Chinese rural elders living in nursing homes. Data for this cross-sectional study were collected by face-to-face interviews in five rural public nursing homes. A total of 205 elders aged 60 years and above were asked to answer a series of questions. Descriptive analysis, independent sample t tests, chi2 tests, and multivariate logistic regression were used to show the prevalence and related factors of SA. The prevalence of SA in this population is 17.6% based on a multidimensional construct composed of: few chronic diseases, good cognitive and physical functioning, good mental health, and active social engagement. The logistic regression results indicate that successful agers are more likely to be younger, married, resilient, and better off economically, whereas gender, education, and social support are not related to SA independently. This model accounts for 45.8% of the variance in SA. These results suggest some tentative recommendations for elders, relevant decision makers or employees in nursing homes, and administrative bodies. More rigorous longitudinal design is necessary to investigate the causality of the related factors and SA. PMID- 29180949 TI - Electrically Oscillating Plasmonic Nanoparticles for Enhanced DNA Vaccination against Hepatitis C Virus. AB - The promise of DNA vaccines is far-reaching. However, the development of potent immunization methods remains a key challenge for its use in clinical applications. Here, an approach for in vivo DNA vaccination by electrically activated plasmonic Au nanoparticles is reported. The electrical excitation of plasmonic nanoparticles can drive vibrational and dipole-like oscillations that are able to disrupt nearby cell membranes. In combination with their intrinsic ability to focus and magnify the electric field on the surface of cells, Au nanoparticles allow enhanced cell poration and facilitate the uptake of DNA vaccine. Mice immunized with this approach showed up to 100-fold higher gene expression compared to control treatments (without nanoparticles) and exhibited significantly increased levels of both antibody and cellular immune responses against a model hepatitis C virus DNA vaccine. This approach can be tuned to establish controlled and targeted delivery of different types of therapeutic molecules into cells and live animals as well. PMID- 29180950 TI - Dissociable Electroencephalograph Correlates of Visual Awareness and Feature Based Attention. AB - Background: The relationship between awareness and attention is complex and controversial. A growing body of literature has shown that the neural bases of consciousness and endogenous attention (voluntary attention) are independent. The important role of exogenous attention (reflexive attention) on conscious experience has been noted in several studies. However, exogenous attention can also modulate subliminal processing, suggesting independence between the two processes. The question of whether visual awareness and exogenous attention rely on independent mechanisms under certain circumstances remains unanswered. Methods: In the current study, electroencephalograph recordings were conducted using 64 channels from 16 subjects while subjects attempted to detect faint speed changes of colored rotating dots. Awareness and attention were manipulated throughout trials in order to test whether exogenous attention and visual awareness rely on independent mechanisms. Results: Neural activity related to consciousness was recorded in the following cue-locked time-windows (event related potential, cluster- based permutation test): 0-50, 150-200, and 750-800 ms. With a more liberal threshold, the inferior occipital lobe was found to be the source of awareness-related activity in the 0-50 ms range. In the later 150 200 ms range, activity in the fusiform and post-central gyrus was related to awareness. Awareness-related activation in the later 750-800 ms range was more widely distributed. This awareness-related activation pattern was quite different from that of attention. Attention-related neural activity was emphasized in the 750-800 ms time window and the main source of attention-related activity was localized to the right angular gyrus. These results suggest that exogenous attention and visual consciousness correspond to different and relatively independent neural mechanisms and are distinct processes under certain conditions. PMID- 29180951 TI - P2X2 Dominant Deafness Mutations Have No Negative Effect on Wild-Type Isoform: Implications for Functional Rescue and in Deafness Mechanism. AB - The P2X2 receptor is an ATP-gated ion channel, assembled by three subunits. Recently, it has been found that heterozygous mutations of P2X2 V60L and G353R can cause autosomal dominant nonsyndromic hearing loss. However, the underlying mechanism remains unclear. The fact that heterozygous mutations cause deafness suggests that the mutations may have dominant-negative effect (DNE) on wild-type (WT) P2X2 isoforms and/or other partners leading to hearing loss. In this study, the effect of these dominant deafness P2X2 mutations on WT P2X2 was investigated. We found that sole transfection of both V60L and G353R deafness mutants could efficiently target to the plasma membrane, like WT P2X2, but exhibit a significantly reduced response to ATP stimulation. Both mutants reduced the channel conductance, but G353R mutation also altered the voltage dependency. Co expression with WT P2X2 could restore the response to ATP. As the ratio of WT P2X2 vs. mutants increased, the response to ATP was also increased. Computer modeling confirmed that both V60L and G353R dominant-deafness mutant subunits do not have any negative effect on WT P2X2 subunit, when assembled as a heterotrimer. Improper docking or defective gating is the more likely mechanism for impaired channel function by these P2X2 deafness mutations. These results suggest that P2X2 dominant deafness mutations do not have negative effects on WT P2X2 isoforms, and that adding additional WT P2X2 could rescue the lost channel function caused by the deafness mutations. These P2X2 dominant deafness mutations may have negative-effects on other partners leading to hearing loss. PMID- 29180952 TI - Maintenance of Positional Identity of Neural Progenitors in the Embryonic and Postnatal Telencephalon. AB - Throughout embryonic development and into postnatal life, regionally distinct populations of neural progenitor cells (NPCs) collectively generate the many different types of neurons that underlie the complex structure and function of the adult mammalian brain. At very early stages of telencephalic development, NPCs become organized into regional domains that each produce different subsets of neurons. This positional identity of NPCs relates to the regional expression of specific, fate-determining homeodomain transcription factors. As development progresses, the brain undergoes vast changes in both size and shape, yet important aspects of NPC positional identity persist even into the postnatal brain. How can NPC positional identity, which is established so early in brain development, endure the many dynamic, large-scale and complex changes that occur over a relatively long period of time? In this Perspective article, we review data and concepts derived from studies in Drosophila regarding the function of homeobox (Hox) genes, Polycomb group (PcG) and trithorax group (trxG) chromatin regulators. We then discuss how this knowledge may contribute to our understanding of the maintenance of positional identity of NPCs in the mammalian telencephalon. Similar to the axial body plan of Drosophila larvae, there is a segmental nature to NPC positional identity, with loss of specific homeodomain transcription factors causing homeotic-like shifts in brain development. Finally, we speculate about the role of mammalian PcG and trxG factors in the long-term maintenance of NPC positional identity and certain neurodevelopmental disorders. PMID- 29180953 TI - Roles of Glial Cells in Sculpting Inhibitory Synapses and Neural Circuits. AB - Glial cells are essential for every aspect of normal neuronal development, synapse formation, and function in the central nervous system (CNS). Astrocytes secrete a variety of factors that regulate synaptic connectivity and circuit formation. Microglia also modulate synapse development through phagocytic activity. Most of the known actions of CNS glial cells are limited to roles at excitatory synapses. Nevertheless, studies have indicated that both astrocytes and microglia shape inhibitory synaptic connections through various mechanisms, including release of regulatory molecules, direct contact with synaptic terminals, and utilization of mediators in the extracellular matrix. This review summarizes recent investigations into the mechanisms underlying CNS glial cell mediated inhibitory synapse development. PMID- 29180955 TI - Dissociable Role of Corticotropin Releasing Hormone Receptor Subtype 1 on Dopaminergic and D1 Dopaminoceptive Neurons in Cocaine Seeking Behavior. AB - The ability of many drugs of abuse, including cocaine, to mediate reinforcement and drug-seeking behaviors is in part mediated by the corticotropin-releasing hormone (CRH) system, in which CRH exerts its effects partly via the CRH receptor subtype 1 (CRHR1) in extra-hypothalamic areas. In fact, CRHR1 expressed in regions of the mesolimbic dopamine (DA) system have been demonstrated to modify cocaine-induced DA release and alter cocaine-mediated behaviors. Here we examined the role of neuronal selectivity of CRHR1 within the mesolimbic system on cocaine induced behaviors. First we used a transgenic mouse line expressing GFP under the control of the Crhr1 promoter for double fluorescence immunohistochemistry to demonstrate the cellular location of CRHR1 in both dopaminergic and D1 dopaminoceptive neurons. We then studied cocaine sensitization, self administration, and reinstatement in inducible CRHR1 knockouts using the CreERT2/loxP in either dopamine transporter (DAT)-containing neurons (DAT-Crhr1) or dopamine receptor 1 (D1)-containing neurons (D1-Crhr1). For sensitization testing, mice received five daily injections of cocaine (15 mg/kg IP). For self administration, mice received eight daily 2 h cocaine (0.5 mg/kg per infusion) self-administration sessions followed by extinction and reinstatement testing. There were no differences in the acute or sensitized locomotor response to cocaine in DAT-Crhr1 or D1-Crhr1 mice and their respective controls. Furthermore, both DAT-Crhr1 and D1-Crhr1 mice reliably self-administered cocaine at the level of controls. However, DAT-Crhr1 mice demonstrated a significant increase in cue induced reinstatement relative to controls, whereas D1-Crhr1 mice demonstrated a significant decrease in cue-induced reinstatement relative to controls. These data demonstrate the involvement of CRHR1 in cue-induced reinstatement following cocaine self-administration, and implicate a bi-directional role of CRHR1 for cocaine craving. PMID- 29180954 TI - Disrupted Co-activation of Interneurons and Hippocampal Network after Focal Kainate Lesion. AB - GABAergic interneurons are known to control activity balance in physiological conditions and to coordinate hippocampal networks during cognitive tasks. In temporal lobe epilepsy interneuron loss and consecutive network imbalance could favor pathological hypersynchronous epileptic discharges. We tested this hypothesis in mice by in vivo unilateral epileptogenic hippocampal kainate lesion followed by in vitro recording of extracellular potentials and patch-clamp from GFP-expressing interneurons in CA3, in an optimized recording chamber. Slices from lesioned mice displayed, in addition to control synchronous events, larger epileptiform discharges. Despite some ipsi/contralateral and layer variation, interneuron density tended to decrease, average soma size to increase. Their membrane resistance decreased, capacitance increased and contralateral interneuron required higher current intensity to fire action potentials. Examination of synchronous discharges of control and larger amplitudes, revealed that interneurons were biased to fire predominantly with the largest population discharges. Altogether, these observations suggest that the overall effect of reactive cell loss, hypertrophy and reduced contralateral excitability corresponds to interneuron activity tuning to fire with larger population discharges. Such cellular and network mechanisms may contribute to a runaway path toward epilepsy. PMID- 29180956 TI - Adolescent Executive Dysfunction in Daily Life: Relationships to Risks, Brain Structure and Substance Use. AB - During adolescence, problems reflecting cognitive, behavioral and affective dysregulation, such as inattention and emotional dyscontrol, have been observed to be associated with substance use disorder (SUD) risks and outcomes. Prior studies have typically been with small samples, and have typically not included comprehensive measurement of executive dysfunction domains. The relationships of executive dysfunction in daily life with performance based testing of cognitive skills and structural brain characteristics, thought to be the basis for executive functioning, have not been definitively determined. The aims of this study were to determine the relationships between executive dysfunction in daily life, measured by the Behavior Rating Inventory of Executive Function (BRIEF), cognitive skills and structural brain characteristics, and SUD risks, including a global SUD risk indicator, sleep quality, and risky alcohol and cannabis use. In addition to bivariate relationships, multivariate models were tested. The subjects (n = 817; ages 12 through 21) were participants in the National Consortium on Alcohol and Neurodevelopment in Adolescence (NCANDA) study. The results indicated that executive dysfunction was significantly related to SUD risks, poor sleep quality, risky alcohol use and cannabis use, and was not significantly related to cognitive skills or structural brain characteristics. In multivariate models, the relationship between poor sleep quality and risky substance use was mediated by executive dysfunction. While these cross-sectional relationships need to be further examined in longitudinal analyses, the results suggest that poor sleep quality and executive dysfunction may be viable preventive intervention targets to reduce adolescent substance use. PMID- 29180957 TI - Age-Related Brain Activation Changes during Rule Repetition in Word-Matching. AB - Objective: The purpose of this study was to explore the age-related brain activation changes during a word-matching semantic-category-based task, which required either repeating or changing a semantic rule to be applied. In order to do so, a word-semantic rule-based task was adapted from the Wisconsin Sorting Card Test, involving the repeated feedback-driven selection of given pairs of words based on semantic category-based criteria. Method: Forty healthy adults (20 younger and 20 older) performed a word-matching task while undergoing a fMRI scan in which they were required to pair a target word with another word from a group of three words. The required pairing is based on three word-pair semantic rules which correspond to different levels of semantic control demands: functional relatedness, moderately typical-relatedness (which were considered as low control demands), and atypical-relatedness (high control demands). The sorting period consisted of a continuous execution of the same sorting rule and an inferred trial-by-trial feedback was given. Results: Behavioral performance revealed increases in response times and decreases of correct responses according to the level of semantic control demands (functional vs. typical vs. atypical) for both age groups (younger and older) reflecting graded differences in the repetition of the application of a given semantic rule. Neuroimaging findings of significant brain activation showed two main results: (1) Greater task-related activation changes for the repetition of the application of atypical rules relative to typical and functional rules, and (2) Changes (older > younger) in the inferior prefrontal regions for functional rules and more extensive and bilateral activations for typical and atypical rules. Regarding the inter-semantic rules comparison, only task-related activation differences were observed for functional > typical (e.g., inferior parietal and temporal regions bilaterally) and atypical > typical (e.g., prefrontal, inferior parietal, posterior temporal, and subcortical regions). Conclusion: These results suggest that healthy cognitive aging relies on the adaptive changes of inferior prefrontal resources involved in the repetitive execution of semantic rules, thus reflecting graded differences in support of task demands. PMID- 29180958 TI - Changing Artificial Playback Speed and Real Movement Velocity Do Not Differentially Influence the Excitability of Primary Motor Cortex during Observation of a Repetitive Finger Movement. AB - Action observation studies have investigated whether changing the speed of the observed movement affects the action observation network. There are two types of speed-changing conditions; one involves "changes in actual movement velocity," and the other is "manipulation of video speed." Previous studies have investigated the effects of these conditions separately, but to date, no study has directly investigated the differences between the effects of these conditions. In the "movement velocity condition," increased velocity is associated with increased muscle activity; however, this change of muscle activities is not shown in the "video speed condition." Therefore, a difference in the results obtained under these conditions could be considered to reflect a difference in muscle activity of actor in the video. The aim of the present study was to investigate the effects of different speed-changing conditions and spontaneous movement tempo (SMT) on the excitability of primary motor cortex (M1) during action observation, as assessed by motor-evoked potentials (MEPs) amplitudes induced by transcranial magnetic stimulation (TMS). A total of 29 healthy subjects observed a video clip of a repetitive index or little finger abduction movement under seven different speed conditions. The video clip in the movement velocity condition showed repetitive finger abduction movements made in time with an auditory metronome, at frequencies of 0.5, 1, 2, and 3 Hz. In the video speed condition, playback of the 1-Hz movement velocity condition video clip was modified to show movement frequencies of 0.5, 2, or 3 Hz (Hz-Fake). TMS was applied at the time of maximal abduction and MEPs were recorded from two right-hand muscles. There were no differences in M1 excitability between the movement velocity and video speed conditions. Moreover, M1 excitability did not vary across the speed conditions for either presentation condition. Our findings suggest that changing playback speed and actual differences in movement velocity do not differentially influence M1 excitability during observation of a simple action task, such as repetitive finger movement, and that it is not affected by SMT. In simple and meaningless observational task, people might not be able to recognize the difference in muscle activity of actor in the video. PMID- 29180960 TI - Association of Cerebral Small Vessel Disease Burden and Health-Related Quality of Life after Acute Ischemic Stroke. AB - Objective: Cerebral small vessel disease (SVD) is associated with increased mortality, disability and cognitive decline, depression in stroke survivors. This study examined the association between SVD burden, defined by a combination of SVD markers, and health-related quality of life (HRQoL) in acute ischemic stroke. Methods: Patients admitted with acute ischemic stroke of any etiology were prospectively screened between January 2010 to December 2014 and enrolled in the study if they met study entry criteria. HRQoL was evaluated with the 12-item Stroke Specific Quality of Life (SSQoL) at 3 months after the onset of acute ischemic stroke. SVD was ascertained by the presence of any of the SVD markers including lacune, white matter hyperintensities (WMH), cerebral microbleeds (CMB) and enlarged perivascular spaces (EPVS) in the basal ganglia or their combinations on brain magnetic resonance imaging (MRI). The presence of each individual marker scored 1 point and was summed up to generate an ordinal "SVD score" (0-4) capturing total SVD burden. Linear regression was used to determine the associations between SVD burden and HRQoL. Results: Of the743 acute ischemic stroke patients that formed he study sample (mean age: 66.3 +/- 10.6 years; 41.7% women), 49.3%, 22.5%, 16.0%, 9.2% and 3.1% had SVD scores of 0, 1, 2, 3 and 4, respectively. After adjusting for demographic, clinical and imaging variables, the SVD score was independently associated with lower overall score of SSQoL (B = -1.39, SE = 0.56, p = 0.01), and its domains of mobility (B = -0.41, SE = 0.10, p < 0.001) and vision (B = -0.12, SE = 0.06, p = 0.03). Acute infract volume (B = 1.44, SE = 0.54, p = 0.01), functional independence (B = 5.69, SE = 0.34, p < 0.001) and anxious (B = -1.13, SE = 0.23, p < 0.001) and depressive symptoms (B = -3.41, SE = 0.22, p < 0.001) were also the significant predictors of the overall score of SSQoL. Conclusion: The brain's SVD burden predicts lower HRQoL, predominantly in domains of mobility and vision at 3 months after acute ischemic stroke. The evaluation of SVD burden could facilitate developing individual treatment strategies. PMID- 29180959 TI - Family Income, Cumulative Risk Exposure, and White Matter Structure in Middle Childhood. AB - Family income is associated with gray matter morphometry in children, but little is known about the relationship between family income and white matter structure. In this paper, using Tract-Based Spatial Statistics, a whole brain, voxel-wise approach, we examined the relationship between family income (assessed by income to-needs ratio) and white matter organization in middle childhood (N = 27, M = 8.66 years). Results from a non-parametric, voxel-wise, multiple regression (threshold-free cluster enhancement, p < 0.05 FWE corrected) indicated that lower family income was associated with lower white matter organization [assessed by fractional anisotropy (FA)] for several clusters in white matter tracts involved in cognitive and emotional functions including fronto-limbic circuitry (uncinate fasciculus and cingulum bundle), association fibers (inferior longitudinal fasciculus, superior longitudinal fasciculus), and corticospinal tracts. Further, we examined the possibility that cumulative risk (CR) exposure might function as one of the potential pathways by which family income influences neural outcomes. Using multiple regressions, we found lower FA in portions of these tracts, including those found in the left cingulum bundle and left superior longitudinal fasciculus, was significantly related to greater exposure to CR (beta = -0.47, p < 0.05 and beta = -0.45, p < 0.05). PMID- 29180961 TI - Ginsenoside-Rb1-Mediated Anti-angiogenesis via Regulating PEDF and miR-33a through the Activation of PPAR-gamma Pathway. AB - Angiogenesis is the formation of new blood vessels from the existing vasculature, which is involved in multiple biological processes, including atherosclerosis, ischemic heart disease, and cancer. Ginsenoside-Rb1 (Rb1), the most abundant ginsenoside isolated form Panax ginseng, has been identified as a promising anti angiogenic agent via the up-regulation of PEDF. However, the underlying molecular mechanisms still unknown. In the present study, human umbilical vein endothelial cells (HUVECs) were selected to perform in vitro assays. Rb1 (0-20 nM) treatment induced pigment epithelial-derived factor (PEDF) protein expression in concentration and time-dependent manners. Interestingly, it was also demonstrated that the exposure of Rb1 (10 nM) could increase PEDF protein expression without any alteration on mRNA level, suggesting the involvement of posttranscriptional regulation. Furthermore, bioinformatics predictions indicated the regulation of miR-33a on PEDF mRNA 3'-UTR, which was further confirmed by luciferase reporter gene assay and real-time PCR. Over-expression of pre-miR-33a was found to regress partly Rb1-mediated PEDF increment and anti-angiogenic effect in HUVECs. Additionally, Rb1-reduced miR-33a and increased PEDF expression was prevented by pre-incubation with peroxisome proliferator-activated receptor-gamma (PPAR-gamma) antagonist (GW9662) or transfection with PPAR-gamma siRNA in HUVECs. Taken together, our findings demonstrated that Rb1 exerted anti-angiogenic effects through PPAR-gamma signaling pathway via modulating miR-33a and PEDF expressions. Thus, Rb1 may have the potential of being developed as an anti-angiogenic agent, however, further appropriate studies are warranted to evaluate the effect in vivo. PMID- 29180962 TI - Tetradecyl 2,3-Dihydroxybenzoate Improves the Symptoms of Diabetic Mice by Modulation of Insulin and Adiponectin Signaling Pathways. AB - Background: Tetradecyl 2,3-dihydroxybenzoate (ABG-001) derived from Chinese medicine, gentiana regescens Franch is a leading compound with NGF mimic effect, it can induce neurite outgrowth of PC12 cells via the IGF-1/PI3K/ERK signaling pathway. Thus, we inferred that this compound had anti-diabetic effect and used streptozocin (STZ)-induced diabetic mice to indicate it. Methods: ABG-001 was synthesized with 2,3-dihydroxybenzoic acid and tetradecyl alcohol under certain reaction conditions. STZ-induced diabetic mice were used to investigate anti diabetic effect. Oral glucose tolerance test, insulin tolerance test, RT-PCR, Western blot, ELISA assays and histological section were performed to do the analysis of action mechanism. Results: ABG-001 showed anti-diabetic effect in STZ induced diabetic mice. In diabetic mice, the anti-diabetic effect of ABG-001 at a dose of 20 mg/kg was equal with metformin at a dose of 140 mg/kg. Moreover, glucose tolerance and insulin sensitivity were significantly improved on diabetic mice. The plasma insulin, adiponectin and leptin were notably increased, whereas glucagon remarkably decreased. The gene expressions of adiponectin and leptin in adipose tissue, glucose transporter 4 and adiponectin receptor 1 in liver and gastrocnemius, ADR2 in hypothalamus and pancreas were obviously increased. Conclusion: ABG-001 exerts antidiabetic effects via modulation of insulin and adiponectin signaling pathways. This new type of molecule could be a promising drug candidate for treatment of diabetes.

AB - [This retracts the article on p. 301 in vol. 8, PMID: 28611662.]. PMID- 29180963 TI - Spinal Cord Molecular and Cellular Changes Induced by Adenoviral Vector- and Cell Mediated Triple Gene Therapy after Severe Contusion. AB - The gene therapy has been successful in treatment of spinal cord injury (SCI) in several animal models, although it still remains unavailable for clinical practice. Surprisingly, regardless the fact that multiple reports showed motor recovery with gene therapy, little is known about molecular and cellular changes in the post-traumatic spinal cord following viral vector- or cell-mediated gene therapy. In this study we evaluated the therapeutic efficacy and changes in spinal cord after treatment with the genes encoding vascular endothelial growth factor (VEGF), glial cell-derived neurotrophic factor (GDNF), angiogenin (ANG), and neuronal cell adhesion molecule (NCAM) applied using both approaches. Therapeutic genes were used for viral vector- and cell-mediated gene therapy in two combinations: (1) VEGF+GDNF+NCAM and (2) VEGF+ANG+NCAM. For direct gene therapy adenoviral vectors based on serotype 5 (Ad5) were injected intrathecally and for cell-mediated gene delivery human umbilical cord blood mononuclear cells (UCB-MC) were simultaneously transduced with three Ad5 vectors and injected intrathecally 4 h after the SCI. The efficacy of both treatments was confirmed by improvement in behavioral (BBB) test. Molecular and cellular changes following post-traumatic recovery were evaluated with immunofluorescent staining using antibodies against the functional markers of motorneurons (Hsp27, synaptophysin, PSD95), astrocytes (GFAP, vimentin), oligodendrocytes (Olig2, NG2, Cx47) and microglial cells (Iba1). Our results suggest that both approaches with intrathecal delivery of therapeutic genes may support functional recovery of post traumatic spinal cord via lowering the stress (down regulation of Hsp25) and enhancing the synaptic plasticity (up regulation of PSD95 and synaptophysin), supporting oligodendrocyte proliferation (up regulation of NG2) and myelination (up regulation of Olig2 and Cx47), modulating astrogliosis by reducing number of astrocytes (down regulation of GFAP and vimetin) and microglial cells (down regulation of Iba1). PMID- 29180965 TI - Oxidative Stress and Antioxidant System in Periodontitis. AB - Periodontitis is a common inflammatory disease, which is initiated by bacterial infection and subsequently progressed by aberrant host response. It can result in the destruction of teeth supporting tissues and have an influence on systemic health. When periodontitis occurs, reactive oxygen species, which are overproduced mostly by hyperactive neutrophils, could not be balanced by antioxidant defense system and cause tissues damage. This is characterized by increased metabolites of lipid peroxidation, DNA damage and protein damage. Local and systemic activities of antioxidants can also be influenced by periodontitis. Total antioxidant capacity, total oxidant status and oxidative stress index have been used to evaluate the oxidative stress associated with periodontitis. Studies have confirmed that inflammatory response in periodontitis is associated with an increased local and systemic oxidative stress and compromised antioxidant capacity. Our review focuses on increased oxidative stress in periodontal disease, specifically, on the relationship between the local and systemic biomarkers of oxidative stress and periodontitis and their association with the pathogenesis of periodontitis. Also, the relationship between periodontitis and systemic inflammation, and the effects of periodontal therapy on oxidative stress parameters will be discussed. PMID- 29180966 TI - Parathyroid Hormone-Related Protein Promotes Rat Stem Leydig Cell Differentiation. AB - The regulatory factors for stem Leydig cell development are largely unknown. Herein, we reported that parathyroid hormone-related protein (PTHrP) may be a factor to regulate this process. The effects of PTHrP on rat stem Leydig cell proliferation and differentiation were investigated using a stem Leydig cell culture system and an ethane dimethane sulfonate (EDS)-treated in vivo Leydig cell regeneration model. PTHrP (1,000 pg/ml) significantly increased medium testosterone level and up-regulated STAR, CYP17A1, and 17beta-HSD3 expressions. Co-treatment with PKA inhibitor H-89 or PKC inhibitor U73122 reversed PTHrP mediated increase of testosterone production in vitro. Intratesticular injection of PTHrP (100 ng/testis) into the Leydig cell-depleted testis from post-EDS day 7 to 21 significantly increased serum testosterone level, up-regulated LHCGR, SCARB1, CYP11A1, 11beta-HSD1, and CYP17A1 expressions. It also enlarged Leydig cell size without affecting PCNA-labeled Leydig cell number. This indicates that PTHrP promotes stem Leydig cell differentiation. PTHrP in vivo increased CREB and p-CREB levels, suggesting that PTHrP acts via a PKA-CREB signaling pathway. In conclusion, PTHrP stimulates stem Leydig cell differentiation without affecting its proliferation, showing its novel action and mechanism on rat stem Leydig cell development. PMID- 29180967 TI - Efficacy and Tolerability of Different Interventions in Children and Adolescents with Attention Deficit Hyperactivity Disorder. AB - Background: Our study is an analysis of multiple publications involving assessing the comparable efficacy and tolerability of six interventions, which are lisdexamfetamine dimesylate (LDX), atomoxetine (ATX), methylphenidate (MPH), clonidine hydrochloride (CLON), guanfacine extended release (GXR), and bupropion, for young patients (6-18 years old) suffering from attention deficit hyperactivity disorder (ADHD). Methods: A conventional meta-analysis (MA) was performed to give direct comparisons and a network meta-analysis (NMA) was used to show the combination of direct and indirect evidence. Ranking preference for all the interventions under a certain outcome was given by the surface of cumulative ranking curve area (SUCRA). Results: Overall, 15,025 participants from 73 studies were involved in our analysis. In the pairwise MA, LDX was associated with less withdrawal than ATX for lack of efficacy. MPH showed less effectiveness than LDX according to ADHD Rating Scale score. Based on the analysis of our NMA, significant results of efficacy that LDX is a competitive drug were observed when evaluating LDX in comparison with other drugs except for CLON. ATX and GXR presented higher rates of abdominal pain morbidity versus inactive treatment. Conclusion: The stimulants LDX and MPH are still highly recommended because they are highly effective and are tolerated well by patients. Among the non stimulants, CLON can be taken into consideration for its appreciable effectiveness and tolerability. ATX and GXR can be seen as moderate choices. PMID- 29180969 TI - Effect of Transcranial Direct Current Stimulation on Functional Capacity in Schizophrenia: A Study Protocol for a Randomized Controlled Trial. AB - : Schizophrenia patients elicit a wide range of psychopathology, including psychotic symptoms, mood symptoms, and cognitive impairment. Functional capacity is defined as the ability to perform everyday living skills, which is linked to cognition and real-world functional outcome. In a previous open trial, we demonstrated that transcranial direct current stimulation (tDCS), one of the neuromodulation methods, improved cognition and functional capacity in 28 patients with schizophrenia. However, since it was a pilot study, a controlled trial is needed. Therefore, we present a study protocol for a randomized controlled trial designed to evaluate the effect of tDCS on functional capacity in patients with schizophrenia. This is a two-arm, parallel-design, randomized controlled trial, in which patients and assessors will be blinded. Patients meeting DSM-5 criteria for schizophrenia will be enrolled and randomized to receive either active or sham stimulation (with 10 sessions in five consecutive days). Functional capacity will be evaluated by the UCSD Performance-based Skills Assessment-Brief as primary outcome. Cognition, as measured by the Brief Assessment of Cognition in Schizophrenia, and psychotic symptoms, as measured by the Positive and Negative Syndrome Scale, will also be evaluated. Data will be collected at baseline, immediately after the last stimulation, and 1 and 2 months thereafter. If active stimulation elicits greater effects compared with those of sham stimulation, it may add to the efforts to improve functional outcomes by neuromodulation in patients with schizophrenia.

PMID- 29180968 TI - Food-Predicting Stimuli Differentially Influence Eye Movements and Goal-Directed Behavior in Normal-Weight, Overweight, and Obese Individuals. AB - Obese individuals have been shown to exhibit abnormal sensitivity to rewards and reward-predicting cues as for example food-associated cues frequently used in advertisements. It has also been shown that food-associated cues can increase goal-directed behavior but it is currently unknown, whether this effect differs between normal-weight, overweight, and obese individuals. Here, we investigate this question by using a Pavlovian-to-instrumental transfer (PIT) task in normal weight (N = 20), overweight (N = 17), and obese (N = 17) individuals. Furthermore, we applied eye tracking during Pavlovian conditioning to measure the participants' conditioned response as a proxy of the incentive salience of the predicted reward. Our results show that the goal-directed behavior of overweight individuals was more strongly influenced by food-predicting cues (i.e., stronger PIT effect) than that of normal-weight and obese individuals (p < 0.001). The weight groups were matched for age, gender, education, and parental education. Eye movements during Pavlovian conditioning also differed between weight categories (p < 0.05) and were used to categorize individuals based on their fixation style into "high eye index" versus "low eye index" as well. Our main finding was that the fixation style exhibited a complex interaction with the weight category. Furthermore, we found that normal-weight individuals of the group "high eye index" had higher body mass index within the healthy range than individuals of the group "low eye index" (p < 0.001), but this relationship was not found within in the overweight or obese groups (p > 0.646). Our findings are largely consistent with the incentive sensitization theory predicting that overweight individuals are more susceptible to food-related cues than normal weight controls. However, this hypersensitivity might be reduced in obese individuals, possibly due to habitual/compulsive overeating or differences in reward valuation. PMID- 29180970 TI - Cebranopadol, a Mixed Opioid Agonist, Reduces Cocaine Self-administration through Nociceptin Opioid and Mu Opioid Receptors. AB - Cocaine addiction is a widespread psychiatric condition still waiting for approved efficacious medications. Previous studies suggested that simultaneous activation of nociceptin opioid (NOP) and mu opioid (MOP) receptors could be a successful strategy to treat cocaine addiction, but the paucity of molecules co activating both receptors with comparable potency has hampered this line of research. Cebranopadol is a non-selective opioid agonist that at nanomolar concentration activates both NOP and MOP receptors and that recently reached phase-III clinical trials for cancer pain treatment. Here, we tested the effect of cebranopadol on cocaine self-administration (SA) in the rat. We found that under a fixed-ratio-5 schedule of reinforcement, cebranopadol (25 and 50 ug/kg) decreased cocaine but not saccharin SA, indicating a specific inhibition of psychostimulant consumption. In addition, cebranopadol (50 ug/kg) decreased the motivation for cocaine as detected by reduction of the break point measured in a progressive-ratio paradigm. Next, we found that cebranopadol retains its effect on cocaine consumption throughout a 7-day chronic treatment, suggesting a lack of tolerance development toward its effect. Finally, we found that only simultaneous blockade of NOP and MOP receptors by concomitant administration of the NOP antagonist SB-612111 (30 mg/kg) and naltrexone (2.5 mg/kg) reversed cebranopadol induced decrease of cocaine SA, demonstrating that cebranopadol activates both NOP and classical opioid receptors to exert its effect. Our data, together with the fairly advanced clinical development of cebranopadol and its good tolerability profile in humans, indicate that cebranopadol is an appealing candidate for cocaine addiction treatment. PMID- 29180972 TI - Why Women Wear High Heels: Evolution, Lumbar Curvature, and Attractiveness. AB - Despite the widespread use of high-heeled footwear in both developing and modernized societies, we lack an understanding of this behavioral phenomenon at both proximate and distal levels of explanation. The current manuscript advances and tests a novel, evolutionarily anchored hypothesis for why women wear high heels, and provides convergent support for this hypothesis across multiple methods. Using a recently discovered evolved mate preference, we hypothesized that high heels influence women's attractiveness via effects on their lumbar curvature. Independent studies that employed distinct methods, eliminated multiple confounds, and ruled out alternative explanations showed that when women wear high heels, their lumbar curvature increased and they were perceived as more attractive. Closer analysis revealed an even more precise pattern aligning with human evolved psychology: high-heeled footwear increased women's attractiveness only when wearing heels altered their lumbar curvature to be closer to an evolutionarily optimal angle. These findings illustrate how human evolved psychology can contribute to and intersect with aspects of cultural evolution, highlighting that the two are not independent or autonomous processes but rather are deeply intertwined. PMID- 29180971 TI - Increased Risk of Pulmonary Tuberculosis in Patients with Depression: A Cohort Study in Taiwan. AB - Background/objective: Tuberculosis (TB) and depression were major public health issues worldwide and the mutual causative relationships between them were not exhaustive. This study was performed to explore the association between depression, comorbidities, and the risk of pulmonary TB in Taiwan. Methods: The cohort study used the database of the Taiwan National Health Insurance Program. The depression group included 34,765 subjects aged 20-84 years with newly diagnosed depression from 2000 to 2012, and the non-depression group included 138,187 randomly selected subjects without depression. Both depression and non depression groups were matched with respect to sex, age, and comorbidities. We explored the incidence of pulmonary TB at the end of 2013 in both the groups and used multivariable Cox proportional hazards regression model to explore the hazard ratio (HR) and 95% confidence interval (CI) for the risk of pulmonary TB associated with depression. Results: The overall incidence of pulmonary TB was 1.16-fold greater in the depression group than that in the non-depression group (1.52 vs. 1.31 per 1,000 person-years, 95% CI 1.12, 1.21). The multivariable Cox proportional hazards regression analysis revealed that the adjusted HR of pulmonary TB was 1.15 for the depression group (95% CI 1.03, 1.28), compared with the non-depression group. Conclusion: Depression is associated with 1.15-fold increased hazard of pulmonary TB in Taiwan. PMID- 29180973 TI - Mothers, Intrinsic Math Motivation, Arithmetic Skills, and Math Anxiety in Elementary School. AB - Math anxiety is influenced by environmental, cognitive, and personal factors. Yet, the concurrent relationships between these factors have not been examined. To this end, the current study investigated how the math anxiety of 30 sixth graders is affected by: (a) mother's math anxiety and maternal behaviors (environmental factors); (b) children's arithmetic skills (cognitive factors); and (c) intrinsic math motivation (personal factor). A rigorous assessment of children's math anxiety was made by using both explicit and implicit measures. The results indicated that accessible self-representations of math anxiety, as reflected by the explicit self-report questionnaire, were strongly affected by arithmetic skills. However, unconscious cognitive constructs of math anxiety, as reflected by the numerical dot-probe task, were strongly affected by environmental factors, such as maternal behaviors and mothers' attitudes toward math. Furthermore, the present study provided preliminary evidence of intergenerational transmission of math anxiety. The conclusions are that in order to better understand the etiology of math anxiety, multiple facets of parenting and children's skills should be taken into consideration. Implications for researchers, parents, and educators are discussed. PMID- 29180974 TI - Effects of Two Linguistically Proximal Varieties on the Spectral and Coarticulatory Properties of Fricatives: Evidence from Athenian Greek and Cypriot Greek. AB - Several studies have explored the acoustic structure of fricatives, yet there has been very little acoustic research on the effects of dialects on the production of fricatives. This article investigates the effects of two linguistically proximal Modern Greek dialects, Athenian Greek and Cypriot Greek on the temporal, spectral, and coarticulatory properties of fricatives and aims to determine the acoustic properties that convey information about these two dialects. Productions of voiced and voiceless labiodental, dental, alveolar, palatal, and velar fricatives were extracted from a speaking task from typically speaking female adult speakers (25 Cypriot Greek and 20 Athenian Greek speakers). Measures were made of spectral properties, using a spectral moments analysis. The formants of the following vowel were measured and second degree polynomials of the formant contours were calculated. The findings showed that Athenian Greek and Cypriot Greek fricatives differ in all spectral properties across all places of articulation. Also, the co-articulatory effects of fricatives on following vowel were different depending on the dialect. Duration, spectral moments, and the starting frequencies of F1, F2, F3, and F4 contributed the most to the classification of dialect. These findings provide a solid evidence base for the manifestation of dialectal information in the acoustic structure of fricatives. PMID- 29180975 TI - Experience-Induced Change of Alcohol-Related Risk Perception in Patients with Alcohol Use Disorders. AB - The role of alcohol-related risk perception for effective treatment of alcohol use disorders (AUD) is still unclear. The present study on 101 alcohol-dependent patients undergoing a 10-week AUD treatment protocol investigated the relationship between alcohol-related risk perception and alcohol use with the hypotheses that (1) risk perception changes across treatment, (2) changes vary with treatment-related experiences of abstinence/relapse indicating 'risk reappraisal,' and (3) adjustment of perceived own vulnerability according to 'risk reappraisal hypothesis' predicts abstinence during follow-up. Abstinence during treatment was related to a decrease, and relapse during treatment to a slight increase in perceived own risks. Abstinence during the 3-month follow-up varied with experience-induced risk reappraisal. The results show an impact of risk reappraisal on alcohol use and hence advocate a focus on risk reappraisal in AUD treatment. PMID- 29180976 TI - Are Clowns Good for Everyone? The Influence of Trait Cheerfulness on Emotional Reactions to a Hospital Clown Intervention. AB - Trait cheerfulness predicts individual differences in experiences and behavioral responses in various humor experiments and settings. The present study is the first to investigate whether trait cheerfulness also influences the impact of a hospital clown intervention on the emotional state of patients. Forty-two adults received a clown visit in a rehabilitation center and rated their emotional state and trait cheerfulness afterward. Facial expressions of patients during the clown visit were coded with the Facial Action Coding System. Looking at the total sample, the hospital clown intervention elicited more frequent facial expressions of genuine enjoyment (Duchenne smiles) than other smiles (Non-Duchenne smiles), and more Duchenne smiles went along with more perceived funniness, a higher level of global positive feelings and transcendence. This supports the notion that overall, hospital clown interventions are beneficial for patients. However, when considering individual differences in the receptiveness to humor, results confirmed that high trait cheerful patients showed more Duchenne smiles than low trait cheerful patients (with no difference in Non-Duchenne smiles), and reported a higher level of positive emotions than low trait cheerful individuals. In summary, although hospital clown interventions on average successfully raise the patients' level of positive emotions, not all patients in hospitals are equally susceptible to respond to humor with amusement, and thus do not equally benefit from a hospital clown intervention. Implications for research and practitioners are discussed. PMID- 29180977 TI - Adopting Basic Principles of the United Nations Academic Impact Initiative (UNAI): Can Cultural Differences Be Predicted from Value Orientations and Globalization? AB - The United Nations Academic Impact (UNAI) Initiative has set forth 10 Basic Principles for higher education. In the present study, a 10 item self-report questionnaire measuring personal endorsement of these principles has been tested by self-report questionnaires with university and post-graduate students from Austria, China, Cyprus, India, Nigeria, and Slovakia (total N = 976, N = 627 female, mean age 24.7 years, s = 5.7). Starting from the assumptions of Moral Foundations Theory (MFT), we expected that personal attitudes toward the UNAI Basic Principles would be predicted by endorsement of various moral foundations as suggested by MFT and by the individual's degree of globalization. Whereas for the Austrian, Cypriot, and Nigerian sub- samples this assumption was largely confirmed, for the Chinese, Indian, and Slovak sub- samples only small amounts of the variance could be explained by regression models. All six sub-samples differed substantially with regard to their overall questionnaire responses: by five discriminant functions 83.6% of participants were classified correctly. We conclude that implementation of UNAI principles should adhere closely to the cultural requirements of the respective society and, where necessary should be accompanied by thorough informational campaigns about UN educational goals. PMID- 29180978 TI - Emotion Regulation Ability and Resilience in a Sample of Adolescents from a Suburban Area. AB - Earlier research has identified a remarkable number of related factors to resilience during adolescence. Historically, theoretical treatments of resilience have been focused almost exclusively on psychosocial levels of analysis to derive explanatory models. However, there is insufficient understanding of the role of emotion regulation explaining competent functioning despite the experience of adversity (resilience), especially during adolescence. This study explores the relationship between both, emotional regulation abilities and strategies, and resilience in a sample of adolescents from suburbs high-schools (Jerez de la Frontera, Spain). The study also examines how using different emotional regulation strategies may help the development of resilience levels at this stage. Participants of the study were 164 adolescents ranging from 13 to 16 years old (M = 13.98; SD = 0.66). Emotion regulation was measured using the Cognitive Emotional Regulation Questionnaire (CERQ, Garnefski et al., 2001), and sections D and H of Mayer-Salovey-Caruso Emotional Intelligence Test, a performance test (Emotion Regulation Ability sections, MSCEIT, Spanish version, Mayer et al., 2003). Resilience was evaluated with ERE (Educative Resilience Scale for children and adolescents, Saavedra and Castro, 2009). Verbal Intelligence (Yuste, 1997) and personality traits (Cattell and Cattell, 1986) were assessed as two independent variables. Results supported the idea that emotion regulation ability (MSCEIT, D and H sections, Extremera et al., 2006) is a significant predictor of adolescents' resilience. Moreover, cognitive regulation strategies, such as positive reappraisal, predicted perceived resilience among students. Sociability (A factor of HSPQ, sociability) also correlated with resilience levels. Hence, these results are promising, implying that emotion regulation ability may act as a helpful tool preventing adolescents from irrational risky behaviors, commonly assumed at this developmental stage. PMID- 29180979 TI - Clinical Characteristics and Predictors of Outcome for Onconeural Antibody Associated Disorders: A Retrospective Analysis. AB - Objective: To describe and analyze the clinical characteristics, laboratory data, management, and outcome of patients with onconeural antibody-associated disorders (OAAD) and identify predictors for poor outcome. Methods: This was a retrospective review of all patients with potential OAAD, who were hospitalized in Jinan General Hospital between September 2009 and July 2017. We clarified the diagnosis, collected comprehensive information and categorized patients into three groups: paraneoplastic neurological disorders (PNDs), autoimmune encephalitis (AE), and possible OAAD. Within the three groups, we analyzed a range of clinical and laboratory parameters and used univariate and multivariate regression analysis to identify predictors for poor outcome [modified Rankin Scale (mRS) = 3-6]. Results: From 158 patients, we identified 70 who fulfilled the criteria for OAAD, including 44 men (62.9%) and 26 women (37.1%). There were 38 patients (54.3%) in the PNDs group, 14 patients (20%) in the AE group, and 18 patients (25.7%) in the possible OAAD group. After the last follow-up, 14 (36.8%), 9 (64.2%), and 12 (66.7%) had a good outcome (mRS = 0-2). However, 6 (15.8%), 2 (14.3%), and 3 (16.7%) died, respectively. Univariate analysis showed that duration prior to the hospital (p = 0.0224) and urinary incontinence/retention (p = 0.0043) were associated with poor outcome (mRS = 3 6). After multivariate regression analysis, urinary incontinence/retention (p = 0.0388) and an immunocompromised state (p = 0.0247) remained as significant factors for poor outcome. Conclusion: Urinary incontinence/retention and an immunocompromised state represent significant predictors of a worse prognosis for patients with OAAD. By contrast, cerebrospinal fluid analysis showed that serum autoantibodies and tumor markers, the function of crucial organs, electrophysiology, and radiological findings were not associated with a poor outcome.

PMID- 29180981 TI - Cerebral Microdialysis Monitoring to Improve Individualized Neurointensive Care Therapy: An Update of Recent Clinical Data. AB - Cerebral microdialysis (CMD) allows bedside semicontinuous monitoring of patient brain extracellular fluid. Clinical indications of CMD monitoring are focused on the management of secondary cerebral and systemic insults in acute brain injury (ABI) patients [mainly, traumatic brain injury (TBI), subarachnoid hemorrhage, and intracerebral hemorrhage (ICH)], specifically to tailor several routine interventions-such as optimization of cerebral perfusion pressure, blood transfusion, glycemic control and oxygen therapy-in the individual patient. Using CMD as clinical research tool has greatly contributed to identify and better understand important post-injury mechanisms-such as energy dysfunction, posttraumatic glycolysis, post-aneurysmal early brain injury, cortical spreading depressions, and subclinical seizures. Main CMD metabolites (namely, lactate/pyruvate ratio, and glucose) can be used to monitor the brain response to specific interventions, to assess the extent of injury, and to inform about prognosis. Recent consensus statements have provided guidelines and recommendations for CMD monitoring in neurocritical care. Here, we summarize recent clinical investigation conducted in ABI patients, specifically focusing on the role of CMD to guide individualized intensive care therapy and to improve our understanding of the complex disease mechanisms occurring in the immediate phase following ABI. Promising brain biomarkers will also be described. PMID- 29180983 TI - Therapy-Induced Growth and Sexual Maturation in a Developmentally Infantile Adult Patient with a PROP1 Mutation. AB - Background: Hypopituitarism as a result of PROP1 (prophet of PIT1) mutation represents the most common genetic cause of combined deficiency of pituitary hormones and due to growth retardation it is typically diagnosed in childhood. Case description: We present a unique case report of a prepubertal woman with growth retardation in whom combined pituitary hormone deficiency [central hypopituitarism, hypogonadism, and growth hormone (GH) deficiency] caused by homozygous mutation c.150delA in the PROP1 gene was diagnosed late in young adulthood due to unfavorable life circumstances. Through cautiously combined GH therapy and sex hormone therapy, she has achieved better than expected height (exceeding predictions based on family height) and sexual maturation, including regular menstrual cycles. Conclusion: Early diagnosis of panhypopituitarism due to PROP1 mutation is essential for successful treatment; however, our case report shows that carefully titrated GH treatment and sex hormone substitution, although initiated in adulthood, enable restoration of physiological growth and sexual development in a hormonally infantile adult woman with a PROP1 mutation. PMID- 29180982 TI - Resveratrol for Easing Status Epilepticus Induced Brain Injury, Inflammation, Epileptogenesis, and Cognitive and Memory Dysfunction-Are We There Yet? AB - Status epilepticus (SE) is a medical emergency exemplified by self-sustaining, unceasing seizures or swiftly recurring seizure events with no recovery between seizures. The early phase after SE event is associated with neurodegeneration, neuroinflammation, and abnormal neurogenesis in the hippocampus though the extent of these changes depends on the severity and duration of seizures. In many instances, over a period, the initial precipitating injury caused by SE leads to temporal lobe epilepsy (TLE), typified by spontaneous recurrent seizures, cognitive, memory and mood impairments associated with chronic inflammation, reduced neurogenesis, abnormal synaptic reorganization, and multiple molecular changes in the hippocampus. While antiepileptic drugs are efficacious for terminating or greatly reducing seizures in most cases of SE, they have proved ineffective for easing SE-induced epileptogenesis and TLE. Despite considerable advances in elucidating SE-induced multiple cellular, electrophysiological, and molecular changes in the brain, efficient strategies that prevent SE-induced TLE development are yet to be discovered. This review critically confers the efficacy and promise of resveratrol, a phytoalexin found in the skin of red grapes, for easing SE-induced neurodegeneration, neuroinflammation, aberrant neurogenesis, and for restraining the evolution of SE-induced brain injury into a chronic epileptic state typified by spontaneous recurrent seizures, and learning, memory, and mood impairments. PMID- 29180984 TI - Risk of Transmission of Antimicrobial Resistant Escherichia coli from Commercial Broiler and Free-Range Retail Chicken in India. AB - Multidrug-resistant Escherichia coli infections are a growing public health concern. This study analyzed the possibility of contamination of commercial poultry meat (broiler and free-range) with pathogenic and or multi-resistant E. coli in retail chain poultry meat markets in India. We analyzed 168 E. coli isolates from broiler and free-range retail poultry (meat/ceca) sampled over a wide geographical area, for their antimicrobial sensitivity, phylogenetic groupings, virulence determinants, extended-spectrum-beta-lactamase (ESBL) genotypes, fingerprinting by Enterobacterial Repetitive Intergenic Consensus (ERIC) PCR and genetic relatedness to human pathogenic E. coli using whole genome sequencing (WGS). The prevalence rates of ESBL producing E. coli among broiler chicken were: meat 46%; ceca 40%. Whereas, those for free range chicken were: meat 15%; ceca 30%. E. coli from broiler and free-range chicken exhibited varied prevalence rates for multi-drug resistance (meat 68%; ceca 64% and meat 8%; ceca 26%, respectively) and extraintestinal pathogenic E. coli (ExPEC) contamination (5 and 0%, respectively). WGS analysis confirmed two globally emergent human pathogenic lineages of E. coli, namely the ST131 (H30-Rx subclone) and ST117 among our poultry E. coli isolates. These results suggest that commercial poultry meat is not only an indirect public health risk by being a possible carrier of non-pathogenic multi-drug resistant (MDR)-E. coli, but could as well be the carrier of human E. coli pathotypes. Further, the free-range chicken appears to carry low risk of contamination with antimicrobial resistant and extraintestinal pathogenic E. coli (ExPEC). Overall, these observations reinforce the understanding that poultry meat in the retail chain could possibly be contaminated by MDR and/or pathogenic E. coli. PMID- 29180985 TI - Stratification of Diversity and Activity of Methanogenic and Methanotrophic Microorganisms in a Nitrogen-Fertilized Italian Paddy Soil. AB - Paddy fields are important ecosystems, as rice is the primary food source for about half of the world's population. Paddy fields are impacted by nitrogen fertilization and are a major anthropogenic source of methane. Microbial diversity and methane metabolism were investigated in the upper 60 cm of a paddy soil by qPCR, 16S rRNA gene amplicon sequencing and anoxic 13C-CH4 turnover with a suite of electron acceptors. The bacterial community consisted mainly of Acidobacteria, Chloroflexi, Proteobacteria, Planctomycetes, and Actinobacteria. Among archaea, Euryarchaeota and Bathyarchaeota dominated over Thaumarchaeota in the upper 30 cm of the soil. Bathyarchaeota constituted up to 45% of the total archaeal reads in the top 5 cm. In the methanogenic community, Methanosaeta were generally more abundant than the versatile Methanosarcina. The measured maximum methane production rate was 444 nmol gdwh-1, and the maximum rates of nitrate-, nitrite-, and iron-dependent anaerobic oxidation of methane (AOM) were 57 nmol, 55 nmol, and 56 nmol gdwh-1, respectively, at different depths. qPCR revealed a higher abundance of 'Candidatus Methanoperedens nitroreducens' than methanotrophic NC10 phylum bacteria at all depths, except at 60 cm. These results demonstrate that there is substantial potential for AOM in fertilized paddy fields, with 'Candidatus Methanoperedens nitroreducens' archaea as a potential important contributor. PMID- 29180986 TI - Chlamydia trachomatis Strain Types Have Diversified Regionally and Globally with Evidence for Recombination across Geographic Divides. AB - Chlamydia trachomatis (Ct) is the leading cause of bacterial sexually transmitted diseases worldwide. The Ct Multi Locus Sequence Typing (MLST) scheme is effective in differentiating strain types (ST), deciphering transmission patterns and treatment failure, and identifying recombinant strains. Here, we analyzed 323 reference and clinical samples, including 58 samples from Russia, an area that has not previously been represented in Ct typing schemes, to expand our knowledge of the global diversification of Ct STs. The 323 samples resolved into 84 unique STs, a 3.23 higher typing resolution compared to the gold standard single locus ompA genotyping. Our MLST scheme showed a high discriminatory index, D, of 0.98 (95% CI 0.97-0.99) confirming the validity of this method for typing. Phylogenetic analyses revealed distinct branches for the phenotypic diseases of lymphogranuloma venereum, urethritis and cervicitis, and a sub-branch for ocular trachoma. Consistent with these findings, single nucleotide polymorphisms were identified that significantly correlated with each phenotype. While the overall number of unique STs per region was comparable across geographies, the number of STs was greater for Russia with a significantly higher ST/sample ratio of 0.45 (95% CI: 0.35-0.53) compared to Europe or the Americas (p < 0.009), which may reflect a higher level of sexual mixing with the introduction of STs from other regions and/or reassortment of alleles. Four STs were found to be significantly associated with a particular geographic region. ST23 [p = 0.032 (95% CI: 1-23)], ST34 [p = 0.019 (95% CI: 1.1-25)]; and ST19 [p = 0.001 (95% CI: 1.7-34.7)] were significantly associated with Netherlands compared to Russia or the Americas, while ST 30 [p = 0.031 (95% CI: 1.1-17.8)] was significantly associated with the Americas. ST19 was significantly associated with Netherlands and Russia compared with the Americans [p = 0.001 (95% CI: 1.7-34.7) and p = 0.006 (95% CI: 1.5 34.6), respectively]. Additionally, recombinant strains were ubiquitous in the data set [106 (32.8%)], although Europe had a significantly higher number than Russia or the Americas (p < 0.04), the majority of which were from Amsterdam [43 (87.8%) of 49)]. The higher number of recombinants in Europe indicates selective pressure and/or adaptive diversification that will require additional studies to elucidate. PMID- 29180987 TI - Escherichia coli Fails to Efficiently Maintain the Activity of an Important Flavin Monooxygenase in Recombinant Overexpression. AB - This paper describes the measurement and analysis of in vivo activity and stability of cyclohexanone monooxygenase from Acinetobacter sp. NCIMB 9871 (CHMO), a model Baeyer-Villiger monooxygenase, in the recombinant host Escherichia coli. This enzyme was often described as poorly stable in vitro, and has recently been found to deactivate rapidly in the absence of its essential cofactors and antioxidants. Its stability in vivo was scarcely studied, so far. Under conditions common for the overexpression of CHMO we investigated the ability of the host to support these properties using metabolomics. Our results showed that E. coli failed to provide the intracellular levels of cofactors required to functionally stabilize the enzyme, although the biocatalyst was produced in high concentration, and was invariably detected after protein synthesis had stopped. We thus infer that biotechnological applications of CHMO with this host relied on a residual activity of approximately 5-10%. Other microorganisms might offer a more efficient solution for recombinant production of CHMO and related enzymes. PMID- 29180988 TI - A Waking Review: Old and Novel Insights into the Spore Germination in Streptomyces. AB - The complex development undergone by Streptomyces encompasses transitions from vegetative mycelial forms to reproductive aerial hyphae that differentiate into chains of single-celled spores. Whereas their mycelial life - connected with spore formation and antibiotic production - is deeply investigated, spore germination as the counterpoint in their life cycle has received much less attention. Still, germination represents a system of transformation from metabolic zero point to a new living lap. There are several aspects of germination that may attract our attention: (1) Dormant spores are strikingly well-prepared for the future metabolic restart; they possess stable transcriptome, hydrolytic enzymes, chaperones, and other required macromolecules stabilized in a trehalose milieu; (2) Germination itself is a specific sequence of events leading to a complete morphological remodeling that include spore swelling, cell wall reconstruction, and eventually germ tube emergences; (3) Still not fully unveiled are the strategies that enable the process, including a single cell's signal transduction and gene expression control, as well as intercellular communication and the probability of germination across the whole population. This review summarizes our current knowledge about the germination process in Streptomyces, while focusing on the aforementioned points. PMID- 29180990 TI - The N-Terminus of Human Lactoferrin Displays Anti-biofilm Activity on Candida parapsilosis in Lumen Catheters. AB - Candida parapsilosis is a major cause of hospital-acquired infection, often related to parenteral nutrition administered via catheters and hand colonization of health care workers, and its peculiar biofilm formation ability on plastic surfaces. The mortality rate of 30% points to the pressing need for new antifungal drugs. The present study aimed at analyzing the inhibitory activity of the N-terminal lactoferrin-derived peptide, further referred to as hLF 1-11, against biofilms produced by clinical isolates of C. parapsilosis characterized for their biofilm forming ability and fluconazole susceptibility. hLF 1-11 anti biofilm activity was assessed in terms of reduction of biofilm biomass, metabolic activity, and observation of sessile cell morphology on polystyrene microtiter plates and using an in vitro model of catheter-associated C. parapsilosis biofilm production. Moreover, fluctuation in transcription levels of genes related to cell adhesion, hyphal development and extracellular matrix production upon peptide exposure were evaluated by quantitative real time RT-PCR. The results revealed that hLF 1-11 exhibits an inhibitory effect on biofilm formation by all the C. parapsilosis isolates tested, in a dose-dependent manner, regardless of their fluconazole susceptibility. In addition, hLF 1-11 induced a statistically significant dose-dependent reduction of preformed-biofilm cellular density and metabolic activity at high peptide concentrations only. Interestingly, when assessed in a catheter lumen, hLF 1-11 was able to induce a 2-log reduction of sessile cell viability at both the peptide concentrations used in RPMI diluted in NaPB. A more pronounced anti-biofilm effect was observed (3.5-log reduction) when a 10% glucose solution was used as experimental condition on both early and preformed C. parapsilosis biofilm. Quantitative real time RT-PCR experiments confirmed that hLF 1-11 down-regulates key biofilm related genes. The overall findings suggest hLF 1-11 as a promising candidate for the prevention of C. parapsilosis biofilm formation and to treatment of mature catheter-related C. parapsilosis biofilm formation. PMID- 29180989 TI - ANK1 and DnaK-TPR, Two Tetratricopeptide Repeat-Containing Proteins Primarily Expressed in Toxoplasma Bradyzoites, Do Not Contribute to Bradyzoite Differentiation. AB - Toxoplasma gondii is an important zoonotic pathogen infecting one third of the world population and numerous animals. A key factor to its wide distribution is the ability to interconvert between fast replicating tachyzoites and slowly growing bradyzoites, and to establish lifelong chronic infection in intermediate hosts. Although it is well accepted that stage conversion plays key roles in the pathogenesis and transmission of the parasite, little is known about the molecular mechanisms behind it. Using existing gene expression data from TOXODB and published work, we looked for proteins with novel functional domains and whose expression is up-regulated in the bradyzoite stage, hoping to find molecules that have critical roles in regulating stage conversion and bradyzoite formation. In this study we characterized two such proteins ANK1 and DnaK-TPR, both of which are primarily expressed in bradyzoites and contain novel motifs to mediate protein-protein interactions. Through CRISPR/CAS9 directed gene editing technology, both genes were individually knocked out in type 1 strain TgHB2 and type 2 strain ME49. Disruption of neither of these two genes affected the growth or replication of tachyzoites in vitro, consistent with their minimal expression at this stage. However, mutants lacking ANK1 or DnaK-TPR displayed modest virulence attenuation during mice infection. Surprisingly, inactivation of neither ANK1 nor DnaK-TPR seemed to have a significant impact on bradyzoite differentiation in vitro or cyst formation in vivo. These results suggest that ANK1 and DnaK-TPR probably do not directly contribute to bradyzoite differentiation, but likely affect other aspects of bradyzoite biology. PMID- 29180991 TI - Gut Microbial Dysbiosis Is Associated with Altered Hepatic Functions and Serum Metabolites in Chronic Hepatitis B Patients. AB - Chronic hepatitis B (CHB) is a global epidemic disease that results from hepatitis B virus (HBV) infection and may progress to severe liver failure, including liver fibrosis, cirrhosis and hepatocellular carcinoma. Previous evidence has indicated that the dysbiosis of gut microbiota occurs after liver virus infection and is associated with severe liver disease. The aim of this study is to elucidate the compositional and functional characteristics of the gut microbiota in early-stage CHB and to understand their influence on disease progression. We investigated the gut microbial composition of stool samples from 85 CHB patients with low Child-Pugh scores and 22 healthy controls using the Illumina MiSeq sequencing platform. Furthermore, the serum metabolome of 40 subjects was measured by gas chromatography mass spectrometry. Compared with the controls, significant alteration in the gut microbiota was observed in the CHB patients; 5 operational taxonomic units (OTUs) belonging to Actinomyces, Clostridium sensu stricto, unclassified Lachnospiraceae and Megamonas were increased, and 27 belonging to Alistipes, Asaccharobacter, Bacteroides, Butyricimonas, Clostridium IV, Escherichia/Shigella, Parabacteroides, Ruminococcus, unclassified Bacteria, unclassified Clostridiales, Unclassified Coriobacteriaceae, unclassified Enterobacteriaceae, unclassified Lachnospiraceae and unclassified Ruminococcaceae were decreased. The inferred metagenomic information of gut microbiota in CHB showed 21 enriched and 17 depleted KEGG level-2 pathways. Four OTUs, OTU38 (Streptococcus), OTU124 (Veillonella), OTU224 (Streptococcus), and OTU55 (Haemophilus), had high correlations with hosts' hepatic function indices and 10 serum metabolites, including phenylalanine and tyrosine, which are aromatic amino acids that play pathogenic roles in liver disease. In particular, these 4 OTUs were significantly higher in patients with higher Child-Pugh scores, who also showed diminished phenylalanine and tryptophan metabolisms in the inferred gut metagenomic functions. These compositional and functional changes in the gut microbiota in early-stage CHB patients suggest the potential contributions of gut microbiota to the progression of CHB, and thus provide new insight into gut microbiota-targeted interventions to improve the prognosis of this disease. PMID- 29180992 TI - Phylogenetic Network Analysis Revealed the Occurrence of Horizontal Gene Transfer of 16S rRNA in the Genus Enterobacter. AB - Horizontal gene transfer (HGT) is a ubiquitous genetic event in bacterial evolution, but it seldom occurs for genes involved in highly complex supramolecules (or biosystems), which consist of many gene products. The ribosome is one such supramolecule, but several bacteria harbor dissimilar and/or chimeric 16S rRNAs in their genomes, suggesting the occurrence of HGT of this gene. However, we know little about whether the genes actually experience HGT and, if so, the frequency of such a transfer. This is primarily because the methods currently employed for phylogenetic analysis (e.g., neighbor-joining, maximum likelihood, and maximum parsimony) of 16S rRNA genes assume point mutation-driven tree-shape evolution as an evolutionary model, which is intrinsically inappropriate to decipher the evolutionary history for genes driven by recombination. To address this issue, we applied a phylogenetic network analysis, which has been used previously for detection of genetic recombination in homologous alleles, to the 16S rRNA gene. We focused on the genus Enterobacter, whose phylogenetic relationships inferred by multi-locus sequence alignment analysis and 16S rRNA sequences are incompatible. All 10 complete genomic sequences were retrieved from the NCBI database, in which 71 16S rRNA genes were included. Neighbor-joining analysis demonstrated that the genes residing in the same genomes clustered, indicating the occurrence of intragenomic recombination. However, as suggested by the low bootstrap values, evolutionary relationships between the clusters were uncertain. We then applied phylogenetic network analysis to representative sequences from each cluster. We found three ancestral 16S rRNA groups; the others were likely created through recursive recombination between the ancestors and chimeric descendants. Despite the large sequence changes caused by the recombination events, the RNA secondary structures were conserved. Successive intergenomic and intragenomic recombination thus shaped the evolution of 16S rRNA genes in the genus Enterobacter. PMID- 29180993 TI - Co-carcinogenesis: Human Papillomaviruses, Coal Tar Derivatives, and Squamous Cell Cervical Cancer. AB - Cervical cancer (CC) is the fourth most common cancers among women worldwide. Human papillomaviruses (HPVs) play a major role in the etiology of CC, with several lines of epidemiologic and experimental evidence supporting a role for non-viral (co-carcinogens) and host genetic factors in controlling the risk for progression to neoplasia among HPV-infected individuals. The role of co carcinogens in the development of CC is significant in the developing world where poor sanitation and other socio-economic conditions increase the infectious cancer burden. Here, we discuss how exposure to environmental factors such as coal tar derivatives from cigarette smoking, tar-based sanitary products, and inhaled smoke from biomass-burning stoves, could activate host pathways involved in development of HPV-associated squamous cell cancers in resource-limited settings. Understanding interactions between these pathways with certain oncogenic HPV genotypes may guide implementation of strategies for control and treatment of HPV-associated cancers that develop in populations at high risk of exposure to various co-carcinogens.

AB - Memory B cells and long-lived plasma cells are key elements of adaptive humoral immunity. Regardless of the immunoglobulin class produced, these cells can ensure long-lasting protection but also long-lasting immunopathology, thus requiring tight regulation of their generation and survival. Among all antibody classes, this is especially true for IgE, which stands as the most potent, and can trigger dramatic inflammatory reactions even when present in minute amounts. IgE responses and memory crucially protect against parasites and toxic components of venoms, conferring selective advantages and explaining their conservation in all mammalian species despite a parallel broad spectrum of IgE-mediated immunopathology. Long-term memory of sensitization and anaphylactic responses to allergens constitute the dark side of IgE responses, which can trigger multiple acute or chronic pathologic manifestations, some punctuated with life-threatening events. This Janus face of the IgE response and memory, both necessary and potentially dangerous, thus obviously deserves the most elaborated self-control schemes. PMID- 29180996 TI - Antibody Heavy Chain Variable Domains of Different Germline Gene Origins Diversify through Different Paths. AB - B cells produce antibodies, key effector molecules in health and disease. They mature their properties, including their affinity for antigen, through hypermutation events; processes that involve, e.g., base substitution, codon insertion and deletion, often in association with an isotype switch. Investigations of antibody evolution define modes whereby particular antibody responses are able to form, and such studies provide insight important for instance for development of efficient vaccines. Antibody evolution is also used in vitro for the design of antibodies with improved properties. To better understand the basic concepts of antibody evolution, we analyzed the mutational paths, both in terms of amino acid substitution and insertions and deletions, taken by antibodies of the IgG isotype. The analysis focused on the evolution of the heavy chain variable domain of sets of antibodies, each with an origin in 1 of 11 different germline genes representing six human heavy chain germline gene subgroups. Investigated genes were isolated from cells of human bone marrow, a major site of antibody production, and characterized by next-generation sequencing and an in-house bioinformatics pipeline. Apart from substitutions within the complementarity determining regions, multiple framework residues including those in protein cores were targets of extensive diversification. Diversity, both in terms of substitutions, and insertions and deletions, in antibodies is focused to different positions in the sequence in a germline gene unique manner. Altogether, our findings create a framework for understanding patterns of evolution of antibodies from defined germline genes. PMID- 29180998 TI - Cystatin F Affects Natural Killer Cell Cytotoxicity. AB - Cystatin F is a cysteine peptidase inhibitor which, unlike other cystatin family members, is targeted to endosomal/lysosomal compartments. It is synthesized as an inactive disulfide-linked dimer which is then converted to an active monomer by proteolytic cleavage of 15 N-terminal residues. Cystatin F has been suggested to regulate the cytotoxicity of natural killer (NK) cells by inhibiting the major granzyme convertases, cathepsins C and H. To test this hypothesis, we prepared variants of cystatin F and analyzed their uptake, subcellular trafficking, and peptidase inhibition, as well as their impact on the cytotoxicity of NK-92 cells and primary NK cells. The N-glycosylation pattern is responsible for the secretion, uptake, and subcellular sorting of cystatin F in HeLa and Hek293 cells, whereas the legumain binding site had no effect on these processes. Active, N-terminally truncated, monomeric cystatin F can also be internalized by recipient cells and targeted to endo/lysosomes, affecting also cells lacking the activating peptidase. Cystatin F mutants capable of cell internalization and trafficking through the endo/lysosomal pathway significantly decreased cathepsin C and H activities, both in situ, following transfection and in trans, using conditioned media. Further, incubation of IL-2 stimulated NK-92 and primary NK cells with full-length and N-terminally truncated cystatin F mutants led to suppression of their granule-mediated cytotoxicity. This effect was most significant with the N-terminally truncated mutants. These results suggest that cystatin F can be an important mediator within tumor microenvironment affecting the cytotoxicity of NK cells and consequently antitumor immune response. PMID- 29180997 TI - Inherent X-Linked Genetic Variability and Cellular Mosaicism Unique to Females Contribute to Sex-Related Differences in the Innate Immune Response. AB - Females have a longer lifespan and better general health than males. Considerable number of studies also demonstrated that, after trauma and sepsis, females present better outcomes as compared to males indicating sex-related differences in the innate immune response. The current notion is that differences in the immuno-modulatory effects of sex hormones are the underlying causative mechanism. However, the field remains controversial and the exclusive role of sex hormones has been challenged. Here, we propose that polymorphic X-linked immune competent genes, which are abundant in the population are important players in sex-based immuno-modulation and play a key role in causing sex-related outcome differences following trauma or sepsis. We describe the differences in X chromosome (ChrX) regulation between males and females and its consequences in the context of common X-linked polymorphisms at the individual as well as population level. We also discuss the potential pathophysiological and immune-modulatory aspects of ChrX cellular mosaicism, which is unique to females and how this may contribute to sex-biased immune-modulation. The potential confounding effects of ChrX skewing of cell progenitors at the bone marrow is also presented together with aspects of acute trauma-induced de novo ChrX skewing at the periphery. In support of the hypothesis, novel observations indicating ChrX skewing in a female trauma cohort as well as case studies depicting the temporal relationship between trauma induced cellular skewing and the clinical course are also described. Finally, we list and discuss a selected set of polymorphic X-linked genes, which are frequent in the population and have key regulatory or metabolic functions in the innate immune response and, therefore, are primary candidates for mediating sex-biased immune responses. We conclude that sex-related differences in a variety of disease processes including the innate inflammatory response to injury and infection may be related to the abundance of X-linked polymorphic immune competent genes, differences in ChrX regulation, and inheritance patterns between the sexes and the presence of X-linked cellular mosaicism, which is unique to females. PMID- 29180999 TI - Alarmin S100A8 Activates Alveolar Epithelial Cells in the Context of Acute Lung Injury in a TLR4-Dependent Manner. AB - Alveolar epithelial cells (AECs) are an essential part of the respiratory barrier in lungs for gas exchange and protection against pathogens. Damage to AECs occurs during lung injury and PAMPs/DAMPs have been shown to activate AECs. However, their interplay as well as the mechanism of AECs' activation especially by the alarmin S100A8/A9 is unknown. Thus, our aim was to study the mechanism of activation of AECs (type I and type II) by S100A8 and/or lipopolysaccharide (LPS) and to understand the role of endogenous S100A8/A9 in neutrophil recruitment in the lung. For our studies, we modified a previous protocol for isolation and culturing of murine AECs. Next, we stimulated the cells with S100A8 and/or LPS and analyzed cytokine/chemokine release. We also analyzed the contribution of the known S100-receptors TLR4 and RAGE in AEC activation. In a murine model of lung injury, we investigated the role of S100A8/A9 in neutrophil recruitment to lungs. S100A8 activates type I and type II cells in a dose- and time-dependent manner which could be quantified by the release of IL-6, KC, and MCP-1. We here clearly demonstrate that AEC s are activated by S100A8 via a TLR4-dependent pathway. Surprisingly, RAGE, albeit mainly expressed in lung tissue, plays no role. Additionally, we show that S100A8/A9 is an essential factor for neutrophil recruitment to lungs. We, therefore, conclude that S100A8 promotes acute lung injury via Toll-like receptor 4-dependent activation of AECs. PMID- 29181000 TI - Prenatal Administration of Betamethasone Causes Changes in the T Cell Receptor Repertoire Influencing Development of Autoimmunity. AB - Prenatal glucocorticoids are routinely administered to pregnant women at risk of preterm delivery in order to improve survival of the newborn. However, in half of the cases, birth occurs outside the beneficial period for lung development. Glucocorticoids are potent immune modulators and cause apoptotic death of immature T cells, and we have previously shown that prenatal betamethasone treatment at doses eliciting lung maturation induce profound thymocyte apoptosis in the offspring. Here, we asked if there are long-term consequences on the offspring's immunity after this treatment. In the non-obese diabetic mouse model, prenatal betamethasone clearly decreased the frequency of pathogenic T cells and the incidence of type 1 diabetes (T1D). In contrast, in the lupus-prone MRL/lpr strain, prenatal glucocorticoids induced changes in the T cell repertoire that resulted in more autoreactive cells. Even though glucocorticoids transiently enhanced regulatory T cell (Treg) development, these cells did not have a protective effect in a model for multiple sclerosis which relies on a limited repertoire of pathogenic T cells for disease induction that were not affected by prenatal betamethasone. We conclude that prenatal steroid treatment, by inducing changes in the T cell receptor repertoire, has unforeseeable consequences on development of autoimmune disease. Our data should encourage further research to fully understand the consequences of this widely used treatment. PMID- 29181001 TI - Disease Tolerance Mediated by Phosphorylated Indoleamine-2,3 Dioxygenase Confers Resistance to a Primary Fungal Pathogen. AB - Resistance to primary fungal pathogens is usually attributed to the proinflammatory mechanisms of immunity conferred by interferon-gamma activation of phagocytes that control microbial growth, whereas susceptibility is attributed to anti-inflammatory responses that deactivate immunity. This study challenges this paradigm by demonstrating that resistance to a primary fungal pathogen such as Paracoccidiodes brasiliensis can be mediated by disease tolerance, a mechanism that preserves host fitness instead of pathogen clearance. Among the mechanisms of disease tolerance described, a crucial role has been ascribed to the enzyme indoleamine-2,3 dioxygenase (IDO) that concomitantly controls pathogen growth by limiting tryptophan availability and reduces tissue damage by decreasing the inflammatory process. Here, we demonstrated in a pulmonary model of paracoccidioidomycosis that IDO exerts a dual function depending on the resistant pattern of hosts. IDO activity is predominantly enzymatic and induced by IFN gamma signaling in the pulmonary dendritic cells (DCs) from infected susceptible (B10.A) mice, whereas phosphorylated IDO (pIDO) triggered by TGF-beta activation of DCs functions as a signaling molecule in resistant mice. IFN-gamma signaling activates the canonical pathway of NF-kappaB that promotes a proinflammatory phenotype in B10.A DCs that control fungal growth but ultimately suppress T cell responses. In contrast, in A/J DCs IDO promotes a tolerogenic phenotype that conditions a sustained synthesis of TGF-beta and expansion of regulatory T cells that avoid excessive inflammation and tissue damage contributing to host fitness. Therefore, susceptibility is unexpectedly mediated by mechanisms of proinflammatory immunity that are usually associated with resistance, whereas genetic resistance is based on mechanisms of disease tolerance mediated by pIDO, a phenomenon never described in the protective immunity against primary fungal pathogens. PMID- 29181002 TI - The Effect of Propofol vs. Isoflurane Anesthesia on Postoperative Changes in Cerebrospinal Fluid Cytokine Levels: Results from a Randomized Trial. AB - Introduction: Aside from direct effects on neurotransmission, inhaled and intravenous anesthetics have immunomodulatory properties. In vitro and mouse model studies suggest that propofol inhibits, while isoflurane increases, neuroinflammation. If these findings translate to humans, they could be clinically important since neuroinflammation has detrimental effects on neurocognitive function in numerous disease states. Materials and methods: To examine whether propofol and isoflurane differentially modulate neuroinflammation in humans, cytokines were measured in a secondary analysis of cerebrospinal fluid (CSF) samples from patients prospectively randomized to receive anesthetic maintenance with propofol vs. isoflurane (registered with http://www.clinicaltrials.gov, identifier NCT01640275). We measured CSF levels of EGF, eotaxin, G-CSF, GM-CSF, IFN-alpha2, IL-1RA, IL-6, IL-7, IL-8, IL-10, IP-10, MCP-1, MIP-1alpha, MIP-1beta, and TNF-alpha before and 24 h after intracranial surgery in these study patients. Results: After Bonferroni correction for multiple comparisons, we found significant increases from before to 24 h after surgery in G-CSF, IL-10, IL-1RA, IL-6, IL-8, IP-10, MCP-1, MIP-1alpha, MIP-1beta, and TNF-alpha. However, we found no difference in cytokine levels at baseline or 24 h after surgery between propofol- (n = 19) and isoflurane-treated (n = 21) patients (p > 0.05 for all comparisons). Increases in CSF IL-6, IL-8, IP-10, and MCP-1 levels directly correlated with each other and with postoperative CSF elevations in tau, a neural injury biomarker. We observed CSF cytokine increases up to 10-fold higher after intracranial surgery than previously reported after other types of surgery. Discussion: These data clarify the magnitude of neuroinflammation after intracranial surgery, and raise the possibility that a coordinated neuroinflammatory response may play a role in neural injury after surgery. PMID- 29181003 TI - The Human-Associated Archaeon Methanosphaera stadtmanae Is Recognized through Its RNA and Induces TLR8-Dependent NLRP3 Inflammasome Activation. AB - The archaeon Methanosphaera stadtmanae is a member of the gut microbiota; yet, the molecular cross-talk between archaea and the human immune system and its potential contribution to inflammatory diseases has not been evaluated. Although archaea are as bacteria prokaryotes, they form a distinct domain having unique features such as different cell wall structures and membrane lipids. So far, no microbe-associated molecular patterns of archaea which activate innate immune receptors have been identified. By stimulating human myeloid cells with M. stadtmanae and purified archaeal nucleic acids, we identified both the microorganism and its RNA as potent stimuli for the innate immune system. To dissect the recognition and activation pathways induced by M. stadtmanae, human monocytic BLaER1 knockout cells were generated using the CRISPR/Cas9 system targeting components of TLR and inflammasome signaling. While the recognition of M. stadtmanae is mediated by TLR7 and TLR8, activation of the NLRP3 inflammasome depends solely on TLR8 engagement. Notably, this process resembles hallmarks of both the canonical and the recently described alternative inflammasome activation. Thus, we have demonstrated for the first time the specific recognition of and response to an archaeon by human cells at the molecular level. PMID- 29181004 TI - Identification of Secretory Leukoprotease Inhibitor As an Endogenous Negative Regulator in Allergic Effector Cells. AB - Mast cells, basophils, and eosinophils are central effectors in allergic inflammatory disorders. These cells secrete abundant serine proteases as well as chemical mediators and cytokines; however, the expression profiles and functions of their endogenous inhibitors remain elusive. We found that murine secretory leukoprotease inhibitor (SLPI) is expressed in basophils and eosinophils but in not in mast cells. SLPI-deficient (Slpi-/-) basophils produce more cytokines than wild-type mice after IgE stimulation. Although the deletion of SLPI in basophils did not affect the release of chemical mediators upon IgE stimulation, the enzymatic activity of the serine protease tryptase was increased in Slpi-/- basophils. Mice transferred with Slpi-/- basophils were highly sensitive to IgE mediated chronic allergic inflammation. Eosinophils lacking SLPI showed greater interleukin-6 secretion and invasive activity upon lipopolysaccharide stimulation, and the expression of matrix metalloproteinase-9 by these eosinophils was increased without stimulation. The absence of SLPI increases JNK1 phosphorylation at the steady state, and augments the serine phosphorylation of JNK1-downstream ETS transcriptional factor Elk-1 in eosinophils upon stimulation. Of note, SLPI interacts with a scaffold protein, JNK-interacting protein 3 (JIP3), that constitutively binds to the cytoplasmic domain of toll-like receptor (TLR) 4, suggesting that SLPI controls Elk-1 activation via binding to JIP3 in eosinophils. Mice transferred with Slpi-/- eosinophils showed the exacerbation of chitin-induced allergic inflammation. These findings showed that SLPI is a negative regulator in allergic effector cells and suggested a novel inhibitory role of SLPI in the TLR4 signaling pathways. PMID- 29181005 TI - Induction of Robust B Cell Responses after Influenza mRNA Vaccination Is Accompanied by Circulating Hemagglutinin-Specific ICOS+ PD-1+ CXCR3+ T Follicular Helper Cells. AB - Modified mRNA vaccines have developed into an effective and well-tolerated vaccine platform that offers scalable and precise antigen production. Nevertheless, the immunological events leading to strong antibody responses elicited by mRNA vaccines are largely unknown. In this study, we demonstrate that protective levels of antibodies to hemagglutinin were induced after two immunizations of modified non-replicating mRNA encoding influenza H10 encapsulated in lipid nanoparticles (LNP) in non-human primates. While both intradermal (ID) and intramuscular (IM) administration induced protective titers, ID delivery generated this response more rapidly. Circulating H10-specific memory B cells expanded after each immunization, along with a transient appearance of plasmablasts. The memory B cell pool waned over time but remained detectable throughout the 25-week study. Following prime immunization, H10-specific plasma cells were found in the bone marrow and persisted over time. Germinal centers were formed in vaccine-draining lymph nodes along with an increase in circulating H10-specific ICOS+ PD-1+ CXCR3+ T follicular helper cells, a population shown to correlate with high avidity antibody responses after seasonal influenza vaccination in humans. Collectively, this study demonstrates that mRNA/LNP vaccines potently induce an immunological repertoire associated with the generation of high magnitude and quality antibodies. PMID- 29181006 TI - Protective Effect of Panax notoginseng Root Water Extract against Influenza A Virus Infection by Enhancing Antiviral Interferon-Mediated Immune Responses and Natural Killer Cell Activity. AB - Influenza is an acute respiratory illness caused by the influenza A virus, which causes economic losses and social disruption mainly by increasing hospitalization and mortality rates among the elderly and people with chronic diseases. Influenza vaccines are the most effective means of preventing seasonal influenza, but can be completely ineffective if there is an antigenic mismatch between the seasonal vaccine virus and the virus circulating in the community. In addition, influenza viruses resistant to antiviral drugs are emerging worldwide. Thus, there is an urgent need to develop new vaccines and antiviral drugs against these viruses. In this study, we conducted in vitro and in vivo analyses of the antiviral effect of Panax notoginseng root (PNR), which is used as an herbal medicine and nutritional supplement in Korea and China. We confirmed that PNR significantly prevented influenza virus infection in a concentration-dependent manner in mouse macrophages. In addition, PNR pretreatment inhibited viral protein (PB1, PB2, HA, NA, M1, PA, M2, and NP) and viral mRNA (NS1, HA, PB2, PA, NP, M1, and M2) expression. PNR pretreatment also increased the secretion of pro-inflammatory cytokines [tumor necrosis factor alpha and interleukin 6] and interferon (IFN) beta and the phosphorylation of type-I IFN-related proteins (TANK-binding kinase 1, STAT1, and IRF3) in vitro. In mice exposed to the influenza A H1N1 virus, PNR treatment decreased mortality by 90% and prevented weight loss (by approximately 10%) compared with the findings in untreated animals. In addition, splenocytes from PNR-administered mice displayed significantly enhanced natural killer (NK) cell activity against YAC-1 cells. Taking these findings together, PNR stimulates an antiviral response in murine macrophages and mice that protects against viral infection, which may be attributable to its ability to stimulate NK cell activity. Further investigations are needed to reveal the molecular mechanisms underlying the protective effects of PNR and its components against influenza virus A infection. PMID- 29181008 TI - Engineered Soluble Monomeric IgG1 Fc with Significantly Decreased Non-Specific Binding. AB - Due to the long serum half-life provided by the neonatal Fc receptor (FcRn) recycling, the IgG1 Fc has been pursued as the fusion partner to develop therapeutic Fc-fusion proteins, or as the antibody-derived scaffold that could be engineered with antigen-binding capabilities. In previous studies, we engineered the monomeric Fc by mutating critical residues located on the IgG1 Fc dimerization interface. Comparing with the wild-type dimeric Fc, monomeric Fc might possess substantial advantages conferred by its smaller size, but also suffers the disadvantage of non-specific binding to some unrelated antigens, raising considerable concerns over its potential clinical development. Here, we describe a phage display-based strategy to examine the effects of multiple mutations of IgG1 monomeric Fc and, simultaneously, to identify new Fc monomers with desired properties. Consequently, we identified a novel monomeric Fc that displayed significantly decreased non-specificity. In addition, it exhibited higher thermal stability and comparable pH-dependent FcRn binding to the previous reported monomeric Fc. These results provide baseline to understand the mechanism underlying the generation of soluble IgG1 Fc monomers and warrant the further clinical development of monomeric Fc-based fusion proteins as well as antigen binders. PMID- 29181009 TI - CRISPRi Induced Suppression of Fimbriae Gene (fimH) of a Uropathogenic Escherichia coli: An Approach to Inhibit Microbial Biofilms. AB - Urinary tract infection (UTI) is one the common infections caused by the recalcitrant nature of biofilms, developed after the pathogen has adhered to the inner lining of the urinary tract. Although significant research has been made in recent years to control these types of infection, but as of yet, no approach has sufficiently been able to reduce the prevalence of UTIs. The main objective of this study was to prevent UTIs through targeting the fimH gene, which is the major virulent factor responsible for biofilm formation. The novelty of this work lies in the use of CRISPRi, a gene specific editing tool to control such types of infections. Accordingly, the system was designed to target fimH gene, responsible for bacterial adherence and this approach was successfully validated by performing microscopic, biofilm and adherence assays. PMID- 29181007 TI - Interplay between Natural Killer Cells and Anti-HER2 Antibodies: Perspectives for Breast Cancer Immunotherapy. AB - Overexpression of the human epidermal growth factor receptor 2 (HER2) defines a subgroup of breast tumors with aggressive behavior. The addition of HER2-targeted antibodies (i.e., trastuzumab, pertuzumab) to chemotherapy significantly improves relapse-free and overall survival in patients with early-stage and advanced disease. Nonetheless, considerable proportions of patients develop resistance to treatment, highlighting the need for additional and co-adjuvant therapeutic strategies. HER2-specific antibodies can trigger natural killer (NK) cell mediated antibody-dependent cellular cytotoxicity and indirectly enhance the development of tumor-specific T cell immunity; both mechanisms contributing to their antitumor efficacy in preclinical models. Antibody-dependent NK cell activation results in the release of cytotoxic granules as well as the secretion of pro-inflammatory cytokines (i.e., IFNgamma and TNFalpha) and chemokines. Hence, NK cell tumor suppressive functions include direct cytolytic killing of tumor cells as well as the regulation of subsequent antitumor adaptive immunity. Albeit tumors with gene expression signatures associated to the presence of cytotoxic lymphocyte infiltrates benefit from trastuzumab-based treatment, NK cell-related biomarkers of response/resistance to HER2-specific therapeutic antibodies in breast cancer patients remain elusive. Several variables, including (i) the configuration of the patient NK cell repertoire; (ii) tumor molecular features (i.e., estrogen receptor expression); (iii) concomitant therapeutic regimens (i.e., chemotherapeutic agents, tyrosine kinase inhibitors); and (iv) evasion mechanisms developed by progressive breast tumors, have been shown to quantitatively and qualitatively influence antibody-triggered NK cell responses. In this review, we discuss possible interventions for restoring/enhancing the therapeutic activity of HER2 therapeutic antibodies by harnessing NK cell antitumor potential through combinatorial approaches, including immune checkpoint blocking/stimulatory antibodies, cytokines and toll-like receptor agonists. PMID- 29181011 TI - From IgG Fusion Proteins to Engineered-Specific Human Regulatory T Cells: A Life of Tolerance. AB - Recent efforts have concentrated on approaches to expand and "specify" human regulatory T cells (Tregs) and to apply them to modulate adverse immune responses in autoimmunity and hemophilia. We have used retroviral transduction of specific T-cell receptor, single chain Fv, or antigen domains in Tregs to achieve this goal. Each of these approaches have advantages and disadvantages. Results with these engineered T cells and evolution of the research developments and paths that led to the development of specific regulatory approaches for tolerance are summarized. PMID- 29181010 TI - Crystallizable Fragment Glycoengineering for Therapeutic Antibodies Development. AB - Monoclonal antibody (mAb)-based therapeutics are the fastest growing class of human pharmaceuticals. They are typically IgG1 molecules with N-glycans attached to the N297 residue on crystallizable fragment (Fc). Different Fc glycoforms impact their effector function, pharmacokinetics, stability, aggregation, safety, and immunogenicity. Fc glycoforms affect mAbs effector functions including antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC) by modulating the Fc-FcgammaRs and Fc-C1q interactions. While the terminal galactose enhances CDC activity, the fucose significantly decreases ADCC. Defucosylated immunoglobulin Gs (IgGs) are thus highly pursued as next generation therapeutic mAbs with potent ADCC at reduced doses. A plethora of cell glycoengineering and chemoenzymatic glycoengineering strategies is emerging to produce IgGs with homogenous glycoforms especially without core fucose. The chemoenzymatic glycosylation remodeling also offers useful avenues for site specific conjugations of small molecule drugs onto mAbs. Herein, we review the current progress of IgG-Fc glycoengineering. We begin with the discussion of the structures of IgG N-glycans and biosynthesis followed by reviewing the impact of IgG glycoforms on antibody effector functions and the current Fc glycoengineering strategies with emphasis on Fc defucosylation. Furthermore, we briefly discuss two novel therapeutic mAbs formats: aglycosylated mAbs and Fc glycan specific antibody-drug conjugates (ADCs). The advances in the understanding of Fc glycobiology and development of novel glycoengineering technologies have facilitated the generation of therapeutic mAbs with homogenous glycoforms and improved therapeutic efficacy. PMID- 29181012 TI - Sulfated Polysaccharides in the Freshwater Green Macroalga Cladophora surera Not Linked to Salinity Adaptation. AB - The presence of sulfated polysaccharides in cell walls of seaweeds is considered to be a consequence of the physiological adaptation to the high salinity of the marine environment. Recently, it was found that sulfated polysaccharides were present in certain freshwater Cladophora species and some vascular plants. Cladophora (Ulvophyceae, Chlorophyta) is one of the largest genera of green algae that are able to grow in both, seas and freshwater courses. Previous studies carried out on the water-soluble polysaccharides of the marine species C. falklandica established the presence of sulfated xylogalactoarabinans constituted by a backbone of 4-linked beta-L-arabinopyranose units partially sulfated mainly on C3 and also on C2 with partial glycosylation, mostly on C2, with terminal beta D-xylopyranose or beta-D-galactofuranose units. Besides, minor amounts of 3-, 6- and/or 3,6-linked beta-D-galactan structures, with galactose in the pyranosic form were detected. In this work, the main water soluble cell wall polysaccharides from the freshwater alga Cladophora surera were characterized. It was found that this green alga biosynthesizes sulfated polysaccharides, with a structure similar to those found in marine species of this genus. Calibration of molecular clock with fossil data suggests that colonization of freshwater environments occurred during the Miocene by its ancestor. Therefore, the presence of sulfated polysaccharides in the freshwater green macroalga C. surera could be, in this case, an adaptation to transient desiccation and changes in ionic strength. Retention of sulfated polysaccharides at the cell walls may represent a snapshot of an evolutionary event, and, thus constitutes an excellent model for further studies on the mechanisms of sulfation on cell wall polysaccharides and environmental stress co-evolution. PMID- 29181013 TI - Abiotic Stresses Cause Differential Regulation of Alternative Splice Forms of GATA Transcription Factor in Rice. AB - The GATA gene family is one of the most conserved families of transcription factors, playing a significant role in different aspects of cellular processes, in organisms ranging from fungi to angiosperms. GATA transcription factors are DNA-binding proteins, having a class IV zinc-finger motif CX2CX17-20CX2C followed by a highly basic region and are known to bind a consensus sequence WGATAR. In plants, GATAs are known to be involved in light-dependent gene regulation and nitrate assimilation. However, a comprehensive analysis of these GATA gene members has not yet been highlighted in rice when subjected to environmental stresses. In this study, we present an overview of the GATA gene family in rice (OsGATA) in terms of, their chromosomal distribution, domain architecture, and phylogeny. Our study has revealed the presence of 28 genes, encoding 35 putative GATA transcription factors belonging to seven subfamilies in the rice genome. Transcript abundance analysis in contrasting genotypes of rice-IR64 (salt sensitive) and Pokkali (salt tolerant), for individual GATA members indicated their differential expression in response to various abiotic stresses such as salinity, drought, and exogenous ABA. One of the members of subfamily VII OsGATA23a, emerged as a multi-stress responsive transcription factor giving elevated expression levels in response to salinity and drought. ABA also induces expression of OsGATA23a by 35 and 55-folds in IR64 and Pokkali respectively. However, OsGATA23b, an alternative splice variant of OsGATA23 did not respond to above-mentioned stresses. Developmental regulation of the OsGATA genes based on a publicly available microarray database showed distinct expression patterns for most of the GATA members throughout different stages of rice development. Altogether, our results suggest inherent roles of diverse OsGATA factors in abiotic stress signaling and also throw some light on the tight regulation of the spliced variants of OsGATA genes in response to different environmental conditions. PMID- 29181014 TI - Inspecting the True Identity of Herbal Materials from Cynanchum Using ITS2 Barcode. AB - Cynanchum is a large genus with some important medicinal species in China. The medicinal species in Cynanchum are easily confused, leading to potential safety risks. In this study, the internal transcribed spacer 2 (ITS2) barcode was used to discriminate the medicinal plants in Cynanchum. The identifying capability of ITS2 was assessed using the specific genetic divergence, BLAST1, neighbor-joining (NJ) tree, maximum-likelihood (ML) tree, and single-nucleotide polymorphism (SNP) methods. Results indicated that the intra-specific genetic divergences of Cynanchum species were lower than their inter-specific genetic divergences. Of the 87 samples from 17 species, ITS2 showed a high identification efficiency of 90.8 and 87.4% at the species level through BLAST1 and the nearest distance methods. NJ tree and ML tree also demonstrated the suitability of ITS2 to differentiate Cynanchum species. Meanwhile, a stable SNP was found, and it could accurately authenticate Cynanchum paniculatum and Cynanchum atratum. Furthermore, we collected 64 commercial samples from three commonly used herbal medicines and evaluated the capability of ITS2 to survey their authentication. Of these samples, Cynanchi Atrati Radix et Rhizoma (Baiwei) showed a potential safety problem, and all the 11 test samples were adulterants. In conclusion, ITS2 can distinguish medicinal species in Cynanchum effectively, and its application could greatly improve the identification efficiency and accuracy of commercial herbal medicines in this genus. PMID- 29181015 TI - An Extended Approach to Quantify Triacylglycerol in Microalgae by Characteristic Fatty Acids. AB - Microalgae represent a third generation biofuel feedstock due to their high triacylglycerol (TAG) content under adverse environmental conditions. Microalgal TAG resides in a single cell and serves as a lipid class mixed with complicated compositions. We previously showed that TAG possessed characteristic fatty acids (CFAs) for quantification and was linearly correlated with the relative abundance of CFA within certain limits in microalgae. Here, we defined the application range of the linear correlation between TAG and CFA in the oleaginous microalgae Chlamydomonas reinhardtii and Phaeodactylum tricornutum. In addition, TAG quantification was further expanded to a wide range of levels and the absolute amounts of saturated or monounsaturated CFAs, 16:0 and 18:1n9 of C. reinhardtii and 16:0 and 16:1n7 of P. tricornutum, instead of polyunsaturated CFAs, were verified to be linearly correlated to TAG levels throughout the entire period of nitrogen stress. This approach utilizes a single fatty acid to quantify TAG mixtures, and is rapid, simple and precise, which provides a useful tool for monitoring TAG accumulation of distinct microalgal species and facilitating high throughput mutant screening for microalgae. PMID- 29181016 TI - The Biosynthesis of Unusual Floral Volatiles and Blends Involved in Orchid Pollination by Deception: Current Progress and Future Prospects. AB - Flowers have evolved diverse strategies to attract animal pollinators, with visual and olfactory floral cues often crucial for pollinator attraction. While most plants provide reward (e.g., nectar, pollen) in return for the service of pollination, 1000s of plant species, particularly in the orchid family, offer no apparent reward. Instead, they exploit their often specific pollinators (one or few) by mimicking signals of female insects, food source, and oviposition sites, among others. A full understanding of how these deceptive pollination strategies evolve and persist remains an open question. Nonetheless, there is growing evidence that unique blends that often contain unusual compounds in floral volatile constituents are often employed to secure pollination by deception. Thus, the ability of plants to rapidly evolve new pathways for synthesizing floral volatiles may hold the key to the widespread evolution of deceptive pollination. Yet, until now the biosynthesis of these volatile compounds has been largely neglected. While elucidating the biosynthesis in non-model systems is challenging, nonetheless, these cases may also offer untapped potential for biosynthetic breakthroughs given that some of the compounds can be exclusive or dominant components of the floral scent and production is often tissue-specific. In this perspective article, we first highlight the chemical diversity underpinning some of the more widespread deceptive orchid pollination strategies. Next, we explore the potential metabolic pathways and biosynthetic steps that might be involved. Finally, we offer recommendations to accelerate the discovery of the biochemical pathways in these challenging but intriguing systems. PMID- 29181017 TI - Alternate Modes of Photosynthate Transport in the Alternating Generations of Physcomitrella patens. AB - Physcomitrella patens has emerged as a model moss system to investigate the evolution of various plant characters in early land plant lineages. Yet, there is merely a disparate body of ultrastructural and physiological evidence from other mosses to draw inferences about the modes of photosynthate transport in the alternating generations of Physcomitrella. We performed a series of ultrastructural, fluorescent tracing, physiological, and immunohistochemical experiments to elucidate a coherent model of photosynthate transport in this moss. Our ultrastructural observations revealed that Physcomitrella is an endohydric moss with water-conducting and putative food-conducting cells in the gametophytic stem and leaves. Movement of fluorescent tracer 5(6) carboxyfluorescein diacetate revealed that the mode of transport in the gametophytic generation is symplasmic and is mediated by plasmodesmata, while there is a diffusion barrier composed of transfer cells that separates the photoautotrophic gametophyte from the nutritionally dependent heterotrophic sporophyte. We posited that, analogous to what is found in apoplasmically phloem loading higher plants, the primary photosynthate sucrose, is actively imported into the transfer cells by sucrose/H+ symporters (SUTs) that are, in turn, powered by P-type ATPases, and that the transfer cells harbor an ATP-conserving Sucrose Synthase (SUS) pathway. Supporting our hypothesis was the finding that a protonophore (2,4-dinitrophenol) and a SUT-specific inhibitor (diethyl pyrocarbonate) reduced the uptake of radiolabeled sucrose into the sporangia. In situ immunolocalization of P-type ATPase, Sucrose Synthase, and Proton Pyrophosphatase - all key components of the SUS pathway - showed that these proteins were prominently localized in the transfer cells, providing further evidence consistent with our argument.

AB - Cat Swarm Optimization (CSO) algorithm was put forward in 2006. Despite a faster convergence speed compared with Particle Swarm Optimization (PSO) algorithm, the application of CSO is greatly limited by the drawback of "premature convergence," that is, the possibility of trapping in local optimum when dealing with nonlinear optimization problem with a large number of local extreme values. In order to surmount the shortcomings of CSO, Chaos Quantum-behaved Cat Swarm Optimization (CQCSO) algorithm is proposed in this paper. Firstly, Quantum-behaved Cat Swarm Optimization (QCSO) algorithm improves the accuracy of the CSO algorithm, because it is easy to fall into the local optimum in the later stage. Chaos Quantum behaved Cat Swarm Optimization (CQCSO) algorithm is proposed by introducing tent map for jumping out of local optimum in this paper. Secondly, CQCSO has been applied in the simulation of five different test functions, showing higher accuracy and less time consumption than CSO and QCSO. Finally, photovoltaic MPPT model and experimental platform are established and global maximum power point tracking control strategy is achieved by CQCSO algorithm, the effectiveness and efficiency of which have been verified by both simulation and experiment. PMID- 29181021 TI - Mental Task Evaluation for Hybrid NIRS-EEG Brain-Computer Interfaces. AB - Based on recent electroencephalography (EEG) and near-infrared spectroscopy (NIRS) studies that showed that tasks such as motor imagery and mental arithmetic induce specific neural response patterns, we propose a hybrid brain-computer interface (hBCI) paradigm in which EEG and NIRS data are fused to improve binary classification performance. We recorded simultaneous NIRS-EEG data from nine participants performing seven mental tasks (word generation, mental rotation, subtraction, singing and navigation, and motor and face imagery). Classifiers were trained for each possible pair of tasks using (1) EEG features alone, (2) NIRS features alone, and (3) EEG and NIRS features combined, to identify the best task pairs and assess the usefulness of a multimodal approach. The NIRS-EEG approach led to an average increase in peak kappa of 0.03 when using features extracted from one-second windows (equivalent to an increase of 1.5% in classification accuracy for balanced classes). The increase was much stronger (0.20, corresponding to an 10% accuracy increase) when focusing on time windows of high NIRS performance. The EEG and NIRS analyses further unveiled relevant brain regions and important feature types. This work provides a basis for future NIRS-EEG hBCI studies aiming to improve classification performance toward more efficient and flexible BCIs. PMID- 29181019 TI - Crosstalk between the Androgen Receptor and PPAR Gamma Signaling Pathways in the Prostate. AB - Nuclear receptors are a superfamily of ligand-activated transcription factors that play critical roles in the regulation of normal biological processes and several disease states. Of the nuclear receptors expressed within the prostate, the androgen receptor (AR) promotes the differentiation of prostatic epithelial cells and stimulates production of enzymes needed for liquefaction of semen. Multiple forms of AR also promote the growth of both early and late stage prostate cancers. As a result, drugs that target the AR signaling pathway are routinely used to treat patients with advanced forms of prostate cancer. Data also suggest that a second member of the nuclear receptor superfamily, the peroxisome proliferator activated receptor gamma (PPARgamma), is a tumor suppressor that regulates growth of normal prostate and prostate cancers. Recent studies indicate there is a bidirectional interaction between AR and PPARgamma, with each receptor influencing the expression and/or activity of the other within prostatic tissues. In this review, we examine how AR and PPARgamma each regulate the growth and development of normal prostatic epithelial cells and prostate cancers. We also discuss interactions between the AR and PPARgamma signaling pathways and how those interactions may influence prostate biology.

AB - Aim: To assess the efficacy of 7-day first-line Helicobacter pylori eradication with vonoprazan (VPZ), clarithromycin (CAM), and metronidazole (MNZ) in patients with penicillin allergy. Methods: Patients with penicillin allergy, diagnosed with Helicobacter pylori infection and did not have history of Helicobacter pylori eradication, were eligible for the study. Twenty patients were prospectively treated with 20 mg VPZ twice daily, 200 or 400 mg CAM twice daily, and 250 mg MNZ twice daily for 7 days. We also collected the data from 30 patients retrospectively treated with proton pump inhibitor (PPI), CAM, and MNZ. Safety was evaluated in patients completing an adverse effect questionnaire. Results: Both the intention-to-treat and per-protocol effectiveness of VPZ-based eradication were 100% (95% CI: 86.1-100%; n = 20). The eradication rates of PPI based regimen were 83.3% (95% CI: 65.3-94.4%) in the ITT and 82.7% (95% CI: 64.2 94.2%) in the PP analyses. Abdominal fullness was more frequent in VCM compared to PCM. However, all patients with VCM regimen had taken 100% of their course of medication. Conclusion: Triple therapy with VPZ, CAM, and MNZ is well tolerated and effective for eradicating Helicobacter pylori in patients allergic to penicillin.

AB - Background: The aim of this study was to evaluate the in vivo incidence and the location of fenestrations in a young Italian population by using CBCT. Materials and Methods: Fifty patients who had previously performed CBCT for planning third molar extraction or orthodontic therapy were selected for the study. No previous dental treatment had been performed on these patients. Overall, 1,395 teeth were evaluated. Root fenestrations were identified according to the definition of Davies and the American Association of Endodontists. Data was collected and statistically analyzed. Results: Fenestrations were observed in 159 teeth out of 1,395 (11% of teeth). In the lower jaw, we found 68 fenestrations (5%) and 91 in the maxilla (6,5%). Incisors were the teeth with the highest incidence of fenestrations. Conclusion: The relative common finding (11%) of fenestration supports the need for CBCT exams before any surgical/implant treatment to avoid complications related to the initial presence of fenestrations. CBCT was found to be an effective and convenient tool for diagnosing fenestration. PMID- 29181026 TI - Simple Quantification of Pentosidine in Human Urine and Plasma by High Performance Liquid Chromatography. AB - Pentosidine is an advanced glycation end-product (AGE) and fluorescent cross-link compound. A simple high-performance liquid chromatographic (HPLC) method was developed for the detection and quantification of pentosidine in human urine and plasma. The mobile phase used a gradient system to improve separation of pentosidine from endogenous peaks, and chromatograms were monitored by fluorescent detector set at excitation and emission wavelengths of 328 and 378 nm, respectively. The retention time for pentosidine was 24.3 min and the lower limits of quantification (LLOQ) in human urine and plasma were 1 nM. The intraday assay precisions (coefficients of variation) were generally low and found to be in the range of 5.19-7.49% and 4.96-8.78% for human urine and plasma, respectively. The corresponding values of the interday assay precisions were 9.45% and 4.27%. Accuracies (relative errors) ranged from 87.9% to 115%. Pentosidine was stable in a range of pH solutions, human urine, and plasma. In summary, this HPLC method can be applied in future preclinical and clinical evaluation of pentosidine in the diabetic patients. PMID- 29181027 TI - Dispersive Solid Phase Extraction for the Analysis of Veterinary Drugs Applied to Food Samples: A Review. AB - To achieve analytical success, it is necessary to develop thorough clean-up procedures to extract analytes from the matrix. Dispersive solid phase extraction (DSPE) has been used as a pretreatment technique for the analysis of several compounds. This technique is based on the dispersion of a solid sorbent in liquid samples in the extraction isolation and clean-up of different analytes from complex matrices. DSPE has found a wide range of applications in several fields, and it is considered to be a selective, robust, and versatile technique. The applications of dispersive techniques in the analysis of veterinary drugs in different matrices involve magnetic sorbents, molecularly imprinted polymers, carbon-based nanomaterials, and the Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method. Techniques based on DSPE permit minimization of additional steps such as precipitation, centrifugation, and filtration, which decreases the manipulation of the sample. In this review, we describe the main procedures used for synthesis, characterization, and application of this pretreatment technique and how it has been applied to food analysis. PMID- 29181028 TI - Comparison of the Performance of Urinary Mycobacterium tuberculosis Antigens Cocktail (ESAT6, CFP10, and MPT64) with Culture and Microscopy in Pulmonary Tuberculosis Patients. AB - Pulmonary tuberculosis (TB) is a major global health problem and is one of the top 10 causes of death worldwide. Our study aimed to evaluate the performance of urinary Mycobacterium tuberculosis (Mtb) antigens cocktail (ESAT6, CFP10, and MPT64) compared with culture and microscopy. This descriptive cross-sectional study was conducted in Dr. Hasan Sadikin General Hospital, Bandung, from January 2014 to October 2016. A total of 141 pulmonary tuberculosis patients were included. Sputum samples were examined for acid-fast bacilli (ZN stain) and mycobacterial culture (LJ); the Mtb antigens cocktail was examined in the urine sample. The positivity rate of TB detection from the three methods was as follows: AFB 52/141 (36.9%), culture 50/141 (35.5%), and urinary Mtb antigens cocktail 95/141 (67.4%). Sensitivity, specificity, PPV, and NPV of urinary Mtb antigens cocktail were 68.2%, 33%, 31.6%, and 69.6%, respectively. Validity of combination of both methods with culture as a gold standard yielded sensitivity, specificity, PPV, and NPV of 90%, 28.6%, 40.9%, and 83.8%, respectively. Combination of urinary Mtb antigens cocktail with AFB as a screening test gives a good sensitivity, although the specificity is reduced. Urinary Mtb antigens cocktail can be used as screening test for pulmonary tuberculosis. PMID- 29181029 TI - Incidence and Risk Factors for Infections Requiring Hospitalization, Including Pneumocystis Pneumonia, in Japanese Patients with Rheumatoid Arthritis. AB - Objective: Rheumatoid arthritis (RA) may be complicated by different infections, but risk factors for these are not fully elucidated. Here, we assessed the incidence of and risk factors for infections requiring hospitalization (IRH) including pneumocystis pneumonia (PCP) in patients with RA. Methods: We retrospectively surveyed all RA patients treated at our hospital from 2009 to 2013, for whom data were available on demographic features, medications, comorbidities, and severity of RA. Multivariate logistic regression analysis was applied to calculate adjusted odds ratios (ORs) for factors associated with the occurrence of IRH. Results: In a total of 9210 patient-years (2688 patients), there were 373 IRH (3.7/100 patient-years). Respiratory tract infections were most frequent (n = 154, and additionally 16 PCP), followed by urinary tract infections (n = 50). Significant factors for PCP included higher age (>=70 years; OR 3.5), male sex (6.6), underlying lung disease (3.0), use of corticosteroids (4.8), and use of biologics (5.4). Use of methotrexate (5.7) was positively associated with PCP but negatively with total infections (0.7). Additionally, functional disorders and higher RA disease activity were also related to total infections. Conclusions: Risk factors for infection should be taken into account when deciding treatment for the individual RA patient.

AB - The epoxy fatty acid cis-12,13-epoxy-oleic acid, which acts as a DNA adduct, may be generated during long-term storage of many seed oils, including those used in cooking, with frying oils and fried foods being a major source in the modern human diet. Removal of this epoxy fatty acid from the locus of the N-formyl peptide receptors was associated with recovery from cogwheel rigidity and akinesia as well as with improvement in vibration sense and olfactory perception. PMID- 29181031 TI - Laparoscopic Supracervical Hysterectomy with In-Bag Morcellation in Very Large Uterus. AB - Laparoscopic supracervical hysterectomy (LASH) is a safe and fast minimally invasive approach in hysterectomy. In order to extract the uterine body from the abdominal cavity, one condition for LASH is the morcellation of the tissue. The intra-abdominal dissemination of benign and occult malignant uterine cells is a possible risk of this method, which can be avoided by the use of special bags for laparoscopic in-bag morcellation. We present a case of laparoscopic supracervical hysterectomy with in-bag morcellation in a uterus of more than 1400 g. and describe that this minimal-access surgery is safe and feasible even in very large uteri. This case report is registered in Research Registry under the UIN researchregistry1810. PMID- 29181032 TI - Overt Lower Gastrointestinal Bleeding and Pseudotumor: A Rare Presentation of Cytomegalovirus Infection. AB - Cytomegalovirus (CMV) is a ubiquitous organism which can infect multiple organs of the body. In an immunocompromised patient, it can have a myriad of gastrointestinal manifestations. We report a case of recurrent hematochezia and concomitant pseudotumor in an AIDS (acquired immunodeficiency syndrome) patient attributable to CMV infection. A 62-year-old man with a history of AIDS, noncompliant with highly active antiretroviral therapy (HAART), presented with bright red blood per rectum. Index colonoscopy showed presence of multiple ulcers, colonic stenosis, and mass-like appearing lesion. Biopsy confirmed CMV infection and ruled out malignancy. Cessation of dual antiplatelet therapy and compliance with HAART lead to clinical cessation of bleeding and endoscopic healing of ulcers with complete resolution of colon mass on follow-up colonoscopy. PMID- 29181033 TI - Insulin-Like Growth Factor Binding Protein-6 Alters Skeletal Muscle Differentiation of Human Mesenchymal Stem Cells. AB - Insulin-like growth factor binding protein-6 (IGFBP-6), the main regulator of insulin-like growth factor-2 (IGF-2), is a component of the stem cell niche in developing muscle cells. However, its role in muscle development has not been clearly defined. In this study, we investigated the role of IGFBP-6 in muscle commitment and differentiation of human mesenchymal stem cells derived from the placenta. We showed that placental mesenchymal stem cells (PMSCs) have the ability to differentiate into muscle cells when exposed to a specific culture medium by expressing muscle markers Pax3/7, MyoD, myogenin, and myosin heavy chain in a stage-dependent manner with the ultimate formation of multinucleated fibers and losing pluripotency-associated markers, OCT4 and SOX2. The addition of IGFBP-6 significantly increased pluripotency-associated markers as well as muscle differentiation markers at earlier time points, but the latter decreased with time. On the other hand, silencing IGFBP-6 decreased both pluripotent and differentiation markers at early time points. The levels of these markers increased as IGFBP-6 levels were restored. These findings indicate that IGFBP-6 influences MSC pluripotency and myogenic differentiation, with more prominent effects observed at the beginning of the differentiation process before muscle commitment. PMID- 29181034 TI - FGF2 Attenuates Neural Cell Death via Suppressing Autophagy after Rat Mild Traumatic Brain Injury. AB - Traumatic brain injury (TBI) can lead to physical and cognitive deficits, which are caused by the secondary injury process. Effective pharmacotherapies for TBI patients are still lacking. Fibroblast growth factor-2 (FGF2) is an important neurotrophic factor that can stimulate neurogenesis and angiogenesis and has been shown to have neuroprotective effects after brain insults. Previous studies indicated that FGF2's neuroprotective effects might be related to its function of regulating autophagy. The present study investigated FGF2's beneficial effects in the early stage of rat mild TBI and the underlying mechanisms. One hundred and forty-four rats were used for creating controlled cortical impact (CCI) models to simulate the pathological damage after TBI. Our results indicated that pretreatment of FGF2 played a neuroprotective role in the early stage of rat mild TBI through alleviating brain edema, reducing neurological deficits, preventing tissue loss, and increasing the number of surviving neurons in injured cortex and the ipsilateral hippocampus. FGF2 could also protect cells from various forms of death such as apoptosis or necrosis through inhibition of autophagy. Finally, autophagy activator rapamycin could abolish the protective effects of FGF2. This study extended our understanding of FGF2's neuroprotective effects and shed lights on the pharmacological therapy after TBI. PMID- 29181035 TI - The Immunomodulatory Effects of Mesenchymal Stem Cell Polarization within the Tumor Microenvironment Niche. AB - Mesenchymal stem cells (MSCs) represent a promising tool for cell therapy, particularly for their antitumor effects. This cell population can be isolated from multiple tissue sources and also display an innate ability to home to areas of inflammation, such as tumors. Upon entry into the tumor microenvironment niche, MSCs promote or inhibit tumor progression by various mechanisms, largely through the release of soluble factors. These factors can be immunomodulatory by activating or inhibiting both the adaptive and innate immune responses. The mechanisms by which MSCs modulate the immune response are not well understood. Because of this, the relationship between MSCs and immune cells within the tumor microenvironment niche continues to be an active area of research in order to help explain the apparent contradictory findings currently available in the literature. The ongoing research aims to enhance the potential of MSCs in future therapeutic applications. PMID- 29181036 TI - Microarray Analysis Reveals a Potential Role of lncRNA Expression in 3,4 Benzopyrene/Angiotensin II-Activated Macrophage in Abdominal Aortic Aneurysm. AB - Abdominal aortic aneurysm (AAA) is a fatal disease, and exposure to 3,4 benzopyrene (Bap) is closely related to the development of AAA. We have found that Bap could impair the biological function of endothelial progenitor cells (EPCs), which are associated with the occurrence of AAA. We have also demonstrated that macrophage activation plays a key role in Bap-induced AAA, but the mechanism is unknown. Here, we used a mouse lncRNA array to investigate the expression signatures of lncRNAs and mRNAs in Bap-activated macrophage. A total of 457 lncRNAs and 219 mRNAs were found to be differentially expressed. The function of differential mRNAs was determined by pathway and Gene Ontology analysis. Eight pathways associated with inflammation were upregulated, and seven pathways including cell apoptosis were downregulated. It was worth noting that AGE-RAGE pathway, which was involved in Bap-induced EPC dysfunction, was significantly upregulated in Bap-activated macrophage and may contribute to AAA formation. Thus, lncRNAs may exert a key role in activated macrophages and intervene the core lncRNAs and may inhibit the occurrence of a series of cascade reactions in the macrophages, which may provide potential targets for AAA caused by smoking. PMID- 29181037 TI - The Burden and Trend of Blood-Borne Pathogens among Asymptomatic Adult Population in Akwatia: A Retrospective Study at the St. Dominic Hospital, Ghana. AB - Background: This study was aimed at evaluating the seroprevalence and trend of blood-borne pathogens (HIV, HCV, HBV, and Syphilis) among asymptomatic adults at Akwatia during a four-year period (2013-2016). Materials and Methods: The study was a retrospective analysis of secondary data of blood donors who visited the hospital from January 2013 to December 2016. Archival data from 11,436 prospective donors was extracted. Data included age, sex, and place of residence as well as results of infectious markers (HIV, HBV, HCV, and Syphilis). Results: The prevalence of blood-borne pathogens in the donor population was 4.06%, 7.23%, 5.81%, and 10.42% for HIV, HBV, HCV, and Syphilis infections, respectively. A significant decline in HBV and HCV infections was observed in the general donor population and across genders. HIV infection rate remained steady while Syphilis infections recorded a significantly increasing trend, peaking in the year 2015 (14.20%). Age stratification in HBV infection was significant, peaking among age group 40-49 years (8.82%). Conclusion: Asymptomatic blood-borne pathogen burden was high among the adult population in Akwatia. Gender variations in HBV, HCV, and Syphilis infections in the cumulative four-year burden were observed. Awareness needs to be created, especially in the older generation. PMID- 29181038 TI - Implementing an Oxygen Supplementation and Monitoring Protocol on Inpatient Pediatric Bronchiolitis: An Exercise in Deimplementation. AB - Aim: Our goal in this study is to evaluate the effectiveness of our oxygen (O2) protocol to reduce length of stay (LOS) for children hospitalized with bronchiolitis. Methods: In this retrospective cohort study, the outcomes of children <= 24 months old that were admitted with bronchiolitis and placed on the O2 protocol were compared to historical controls. The primary outcome was hospital length of stay. Secondary outcomes were duration of O2 supplementation, rates of pediatric intensive care unit transfer, and readmission. Results: Groups were not significantly different in age, gender, and rates of respiratory distress score assessment. Significantly more severely ill patients were in the O2 protocol group. There were no significant differences between control and O2 protocol groups with regard to mean LOS, rates of pediatric intensive care unit transfer, or seven-day readmission rates. By multiple regression analysis, the use of the O2 protocol was associated with a nearly 20% significant decrease in the length of hospitalization (p = 0.030). Conclusion: Use of O2 supplementation protocol increased LOS in the more ill patients with bronchiolitis but decreased overall LOS by having a profound effect on patients with mild bronchiolitis. PMID- 29181039 TI - Epidemiology and Genetic Diversity of Colistin Nonsusceptible Nosocomial Acinetobacter baumannii Strains from Russia for 2013-2014. AB - A high level of resistance to carbapenems in Acinetobacter baumannii strains severely limits therapeutic possibilities. Colistin is the last resort drug against such strains, although the cases of resistance to this drug have become more frequent. This article presents the epidemiological features and genetic diversity of colistin nonsusceptible A. baumannii strains collected as part of a national multicenter epidemiological study of the antibiotic resistance of pathogens of nosocomial infections (MARATHON), which was conducted in 2013-2014 in Russia. A total of 527 A. baumannii isolates were collected, 10 (1.9%) of which were nonsusceptible to colistin. The majority of nonsusceptible A. baumannii isolates to colistin showed resistance to carbapenems and had the genes of the acquired OXA-40-like carbapenemases (n = 6). In one case, a combination of OXA-23-like + OXA-40-like (n = 1) genes was identified. One strain had the multidrug-resistant (MDR) phenotype, 6 isolates had extensively drug-resistant (XDR) phenotype, and 3 isolates had pandrug-resistant (PDR) phenotype. Among the colistin nonsusceptible A. baumannii isolates, 6 individual genotypes were identified, most of which belonged to successful international clones (CC92OXF/CC2PAS, n = 4; CC944OXF/ST78PAS, n = 4; CC109OXF/CC1PAS, n = 1). PMID- 29181040 TI - Is there a determining factor that predicts mortality in patients with congenital diaphragmatic hernia? AB - Aim: This study was designed to investigate the factors affecting the prognosis in neonates with congenital diaphragmatic hernia (CDH) who were treated in our clinic. These factors included prenatal lung-head ratio (LHR), prenatal stomach and liver presence in the thorax, blood gases in the first 24 h and the modified ventilation index (MVI). Material and methods: The study was carried out retrospectively in 30 neonates with prenatally diagnosed left CDH who were treated in our clinic between January 2007 and 2013. Data were collected, evaluated, and statistically analyzed for gender, birth weight, gestational age, prenatal LHR, prenatal presence of stomach and liver in the thorax, postnatal initial blood gases in the first 24 h and MVI. Results: The median LHR for non survivors was 1.49 and for survivors 1.51. No statistically significant difference in LHR was detected between survivors and non-survivors. In 19 neonates, prenatal ultrasonography (USG) revealed intrathoracic stomach, and 9 of these infants died. Intrathoracic liver was seen in 15 neonates, and 9 of these died. A statistically significant difference was not found between survivors and non-survivors in the intrathoracic liver or intrathoracic stomach neonates. A comparison between the non-survivors and survivors showed a median pH value of 7.10 in non-survivors and 7.24 in survivors (p = 0.002). The median PaCO2 value was 69.4 mm Hg in non-survivors and 51.9 mm Hg in survivors (p = 0.01). There were statistically significant differences in pH and PaCO2 values. The median value of MVI was 33 in survivors and 100 in non-survivors. There was a statistically significant difference between overall non-survivors and survivors in the MVI value (p < 0.05). Conclusions: Based on the findings, postnatal pH, and PaCO2 and MVI values are favorable prognostic factors in CDH in our selected group of patients. PMID- 29181041 TI - Video-assisted thoracic surgery in hemothorax evacuation after cardiac surgery or cardiac interventions. AB - Introduction: Cardiac surgery and cardiac interventions are associated with the risk of iatrogenic complications, including hemothorax. Minimally invasive methods of evacuating hemothorax include video-assisted thoracic surgery (VATS). Aim: This paper presents this method and provides its detailed analysis. Material and methods: The VATS procedures were used to evacuate hemothorax in 8 patients (7 after cardiac surgery and 1 after a cardiac intervention). Complete three-port VATS was performed in 7 patients, while 1 patient underwent assisted VATS due to a large number of adhesions. Results: On average, the repeat procedures were performed on the 20th postoperative day (10th-58th postoperative day). In 6 (75%) cases the VATS intervention was the third surgical intervention performed. One patient, operated on 12 days after the original procedure, was diagnosed with active arterial bleeding, which required conversion to a classic procedure using median sternotomy. No postoperative wound infection was noted. Complete hemothorax removal was achieved in all patients. Conclusions: Classic median sternotomy is the standard approach for hemothorax evacuation. However, it may sometimes be burdened with a high perioperative risk due to massive mediastinal adhesions in the late postoperative period. Additionally, access through the postoperative wound appears to be associated with a higher risk of local infection and sternal instability. Hemodynamically stable patients in the late postoperative period, with stable sternums and healed postoperative wounds, are good candidates for VATS aiming to evacuate hemothorax. The VATS is an effective procedure for evacuating hemothorax. PMID- 29181042 TI - Associations between coronary artery disease, aneurysm and ectasia. AB - Aim: Investigation the frequency and contribution of coronary artery aneurysm/ectasia in addition to their correlation with coronary artery disease (CAD). Material and methods: We retrospectively evaluated the coronary angiography records of 6500 adult consecutive patients, and 418 of them were met inclusion criteria and used in the present study. The CAD was defined as the presence of angiographic coronary stenosis of > 50% of the luminal diameter in no less than one of the epicardial coronary arteries. Moreover, the prevalence and features of the coronary artery aneurysm/ectasia among the cases with and without CAD were compared. Results: We observed coronary artery aneurysm (CAA) and ectasia (CAE) in 6.6% of the patients with significant CAD (+), and 6.1% of the patients with significant CAD (-) (p = 0.2). The percentage of coronary artery aneurysms was significantly higher in CAD (+) patients than in CAD (-) patients (0.8% vs. 0.4%, p = 0.015). The percentage of coronary artery ectasia showed no variation between CAD (+) patients and CAD (-) patients (5.8% vs. 5.7%, p = 0.47). The frequency of spotting aneurysm on a single coronary artery was higher than discerning aneurysm on two or three coronary arteries. Conclusions: Presence of CAA or CAE cases is often encountered in those who have undergone angiography procedures. Furthermore, CAA and CAE should not be considered as simple dilations of vessels. Further studies are needed to determine the effective procedures for the treatment and prognostic evaluations of the patients with CAA or CAE. PMID- 29181043 TI - Results of open heart surgery in Jehovah's Witness patients. Single centre experience. AB - Aim: Evaluation the results in patients from the religious community of Jehovah's Witness (JW) undergoing open heart surgery at our institution. Material and methods: Between September 2011 and March 2015, 21 patients with a religious background of the JW church underwent open heart surgery at our institution performed by the same surgical team. Mean age was 68.43 +/-8.93 years. There were 13 (61.9%) female patients. Recombinant human erythropoietin was administered to every patient with a hemoglobin value < 12.0 g/dl. Nine patients undergoing isolated coronary artery revascularization were operated on without cardiopulmonary bypass. Seven patients underwent combined surgery and 5 patients underwent aortic valve replacement via ministernotomy. The mean follow-up time was 16.45 +/-11.09 months (range: 1.67-44.3 months). Results: Mean baseline hematocrit serum level was 40.15 +/-3.34% (range: 34.5-46.1%). Perioperatively the hematocrit serum levels decreased to the mean level of 29.89 +/-4.31% (range: 21.4-36.3%). The mean hematocrit value at discharge was 30.85 +/-3.59% (range: 23.5-38.4%). One death was observed in the perioperative period. Five (24%) patients suffered from sternum wound infection requiring vacuum-assisted therapy. During the follow-up period 1 patient died due to a non-cardiac related cause. Conclusions: After careful preoperative preparation the results of open heart surgery in JW were very good, including combined procedures. The decrease of hematocrit serum levels significantly characterizing the postoperative period was highly acceptable in this series. Nevertheless, the number of sternum wound infections was a limiting factor for prompt postoperative recovery. PMID- 29181044 TI - Clinical features, management and mortality in diabetic and non-diabetic patients with heart failure - observations from the COMMIT-HF registry. AB - Introduction: Diabetes mellitus (DM) and heart failure (HF) are two common diseases that often co-exist. Aim: To explore clinical characteristics, management strategies and rates of 3-year mortality among diabetic and non diabetic patients hospitalised in a highly specialized interventional cardiology centre. Material and methods: We used data from COMMIT-HF (COnteMporary Modalities In Treatment of Heart Failure), which is a single-centre, observational, prospective registry of patients with symptomatic chronic systolic HF (LVEF < 35%). Data collected included demographics, clinical characteristics, medical history, inpatient therapies and procedures. Follow-up was based on the information acquired from the national health-care provider. Results: We analysed 1397 patients out of the total of 1798 patients included in the COMMIT-HF registry between 2009 and 2013. We identified 595 (42.6%) diabetic and 802 (57.4%) non-diabetic patients. Compared to patients without DM, patients with type 2 DM had a higher rate of comorbidity. Frequency of death in patients with DM during the 3-year follow-up was significantly higher than in patients without DM (199 (33.4%) vs. 163 (20.3%), p < 0.0001, respectively). Conclusions: In the analysed HF population representing patients receiving typical, everyday clinical care, the prevalence of DM is 42.6%. Diabetes mellitus has deleterious effects on renal function and symptoms as assessed by the New York Heart Association functional class. DM remains associated with increased frequency of death in patients with HF, in spite of recent pharmacological and device-based advances in HF management. PMID- 29181045 TI - Late subclinical hemolysis and long-term outcomes after aortic valve replacement with On-X mechanical prostheses - a preliminary single-center report. AB - Introduction: Aortic valve replacement (AVR) with a mechanical prosthesis is not free from late complications. Aim: To evaluate the prevalence of subclinical hemolysis after AVR with On-X prostheses and assess its impact on long-term outcomes. Material and methods: The prospective study included 84 consecutive patients aged 58.3 +/-10.3 years who underwent AVR. They were retrospectively split into group H (n = 12; 14.3%) with prosthesis-related subclinical hemolysis and a control group (C; n = 72; 85.7%). All operations were performed via median sternotomy using cardio-pulmonary bypass. At the end of follow-up, echocardiography was carried out and blood samples for morphology and biochemistry (lactate dehydrogenase (LDH), bilirubin, haptoglobin) were taken. Results: The rate of subclinical hemolysis in patients with properly working prostheses was 14.3% and it was the highest (33.3%) for the smallest valves. Although an improvement in functional status was noted in both groups, it was less evident in group H than in group C (p = 0.007). At the end of follow-up, 97.2% in group C and 75.0% in group H were found in NYHA classes I and II. Patients in group H had significantly lower hemoglobin, hematocrit, and haptoglobin and higher LDH activity than group C subjects. In group H, systolic gradients of On-X valves were higher whereas effective orifice area was smaller than in group C. Conclusions: Our study proved that prosthesis-induced subclinical hemolysis is seen even after implantation of the latest generation mechanical prostheses, particularly of small diameter, and its degree may impact late outcome. PMID- 29181046 TI - Role of dual source multidetector row cardiac computed tomography angiography in diagnosis and management of congenital heart disease patients. AB - Introduction: Primary evaluation of patients with congenital heart disease (CHD) traditionally relies on echocardiography and conventional cardiac angiography (CCA), both of which have potential limitations. Aim: To test the hypothesis that cardiac computed tomography angiography (CCTA) is useful in the diagnosis and management of these patients. Material and methods: The 3-year observational, analytical, retrospective, cohort study included a total of 111 tomographic studies of patients with congenital heart disease. Computed tomography scans were read twice and medical records were reviewed. The Aristotle complexity was assessed as well as and the contribution of new data in relation to clinical suspicion and diagnostic change was evaluated by two expert readers who were blinded for clinical outcome in consensus reading. The confidence interval was set at 95% and a p-value of < 0.05 was used as the cutoff for statistical significance. Results: In total, 111 patients were included (56 men and 55 women) with a mean age of 7.2 years (1 day-71 years). The therapeutic procedure was performed without additional tests in 85.8% of patients. New findings were observed in 60.4% of patients and a subsequent change in management in 46.9%. New unexpected findings in CCTA prompted changes in management in 86.8% of patients. There were no significant differences in age between patients with new findings vs. patients without such findings in CCTA suggesting that CCTA-supported diagnosis of CHD is independent of age. Conclusions: Use of dual-source cardiac computed tomography yields good diagnostic performance in congenital heart disease, prompts changes in management in more than one-third of patients, and reveals new findings in relation to the presumed diagnosis in most patients.

PMID- 29181047 TI - Approaching the 50th anniversary of the first Fontan procedure. What is the current state of treatment provided to patients with functional single ventricles? AB - Nearly 50 years after the pioneering procedure performed by Francis Fontan and Eugene Baudet, which has saved the lives of thousands of children, there are still more questions than answers regarding therapeutic management. The complex pathophysiology of Fontan circulation, the lack of clear guidelines, and the shift in the care of such patients from pediatric cardiological and cardiac surgical centers to ones dealing with adult patients, cause new threats. This paper outlines the fundamental issues related to the pathophysiology of Fontan circulation and reviews the literature on the methods of treating complications characteristic of this group of patients.

However, the prognostic value of individual Notch pathway members in RC subtypes remains indefinable. The present study investigates whether the differential expression of Notch members has a contrary effect on disease-free survival (DFS) in clear cell renal cell carcinoma (KIRC), papillary cell renal cell carcinoma (KIRP) and chromophobe renal cell carcinoma (KICH) patients. Material and methods: The predictive value of 19 Notch members was evaluated in KICH, KIRC and KIRP patient cohorts from The Cancer Genome Atlas (TCGA). Results in the form of Kaplan-Meier survival plots with the p-value calculated (log-rank test, p < 0.05) enabled the patients to be split into favourable/unfavourable prognosis groups regarding expression of Notch members. Results: More specifically, lowered expression of ADAM17 correlated with good prognosis in KICH, KIRC and KIRP (HR = 7.79, p = 0.03; HR = 3.98, p = 0.051; HR = 11.24, p < 0.001, respectively). Additionally, HES4 differentiated KICH and KIRC, as its higher expression correlated with good prognosis in KICH and favourable lowered expression in KIRC (HR = 0.11, p = 0.015; HR = 2.42, p < 0.001, respectively). Conclusions: Our analysis could be valuable for better understanding of the molecular mechanism of renal carcinoma. The expression of Notch pathway members could be a useful biomarker for predicting favourable/unfavourable prognosis in patients with RCC. PMID- 29181055 TI - Functions of the AP-2alpha gene in activating apoptosis and inhibiting proliferation of gastric cancer cells both in vitro and in vivo. AB - Introduction: This study was designed to investigate the potential function of the activating protein 2alpha (AP-2alpha) gene in controlling the proliferation and apoptosis of gastric cancer. Material and methods: Gastric cancer cell line MCG-803 cells and normal cell line GES-1 cells were selected to transfect pcDNA3.1(+)-AP-2alpha and pcDNA3.1(+) plasmids, respectively. Both mRNA and protein levels of AP-2alpha in each group transfected with the pcDNA3.1(+)-AP 2alpha plasmids were up-regulated after 48 h by real-time PCR and Western blotting analysis, leading to marked proliferation inhibition and significant cell cycle arrest. Results: pcDNA3.1(+)-AP-2alpha reduced tumor tissue growth in a subcutaneous tumor gastric carcinoma nude mouse model. Protein over-expression of AP-2alpha in the nude mouse model was accompanied by down-regulation of Blc-2 and ErbB2, resulting in the up-regulation of caspase-3, -8, and -9, ERalpha and p21WAF1/CIP1. Conclusions: The reintroduction of the AP-2alpha gene by pcDNA3.1 could inhibit gastric tumor growth in vitro and in vivo, which may be an alternative future therapeutic molecular target for human gastric cancer. PMID- 29181056 TI - Prognostic implications of phosphatidylinositol 3-kinase/AKT signaling pathway activation in gastric carcinomas. AB - Introduction: Activation of the phosphatidylinositol 3-kinase (PI3K)/AKT pathway plays a critical role in carcinogenesis and resistance to anticancer drugs. In this study, gastric carcinomas (GC) were investigated and statistical analyses were performed concerning the correlation between the clinicopathological features and activation of the PI3K/AKT pathway. Material and methods: Immunohistochemistry for p-AKT, p-mTOR and PTEN was performed in 239 GC and 200 non-neoplastic gastric tissues. The clinicopathological parameters were recorded from the medical charts. Statistical significance was defined by a p-value < 0.05. Results: High p-AKT expression was observed in 10% of the normal gastric tissue and in 90% of GC, and it was significantly associated with tumor size (p < 0.001), T3/T4 tumors (p < 0.001), and presence of metastases (p = 0.02). Similarly, p-mTOR positivity was found in GC cells, but not in the normal gastric mucosa, and was correlated with perineural invasion (p = 0.02) and T3/T4 tumors (p = 0.03). On the other hand, PTEN expression was weak and focal in the tumor cells, while in the normal gastric tissue this staining was strong and diffuse. Importantly, the expression of p-mTOR and PTEN was associated with overall survival. Conclusions: The results of the present study, characterized by the loss of PTEN expression and higher expression of p-AKT and p-mTOR in the majority of tumor cells, apparently are implicated in the carcinogenesis and progression of GC. The identification of p-mTOR and PTEN expression as prognostic factors corroborates the identification and use of potential target drugs that could be more efficient for the treatment of these patients. PMID- 29181057 TI - Tissue expression of beta-catenin and E- and N-cadherins in chronic hepatitis C and hepatocellular carcinoma. AB - Introduction: The role of Wnt/ beta -catenin signaling pathway in HCV-associated hepatocellular carcinogenesis is still unknown. Material and methods: This study aimed to perform quantitative analysis of immuno- and hybridocytochemical expression of beta -catenin, E- and N-cadherins and HCV proteins (C, NS3, NS5A) in long-lasting (>= 20 years) chronic hepatitis C (CH-C) (n = 54), hepatocellular carcinoma (HCC) (n = 61), and control liver samples (n = 8). Results: Typical membranous expression of beta -catenin in the control liver was higher than in the CH-C and HCC (p = 0.06). The mean beta -catenin tissue expression in CH-C was similar to controls, and significantly higher than that of HCC (p = 0.005). E cadherin expression was lower in CH-C than in the control (p = 0.045) and HCC (p < 0.001). In HCC both beta -catenin and E-cadherin expressions were significantly lower in comparison to controls (p = 0.02, p = 0.001, respectively). Positive correlations were found between beta -catenin and E-cadherin (in CH-C and HCC), beta -catenin and N-cadherin (HCC), E- and N-cadherins expressions (HCC) (p < 0.05 in all cases). In CH-C the positive correlation was demonstrated between NS5A protein and beta -catenin, and between the all HCV proteins (C, NS3, NS5A) and E-cadherin expression (p < 0.05 in all cases). Conclusions: Alterations in cellular locations of beta -catenin and E-cadherin in CH-C and HCC pointed to structural disturbances in intercellular junctions in the livers and presence of the transcriptionally inactive form of beta -catenin. The reduced expression of E cadherin in long-lasting CH-C may represent an early indicator of the epithelial mesenchymal transition. The most important role in modulation of the Wnt/ beta catenin pathway in vivo is probably played by the NS5A viral protein. PMID- 29181058 TI - Value of CNRIP1 promoter methylation in colorectal cancer screening and prognosis assessment and its influence on the activity of cancer cells. AB - Introduction: The aim of the study was to investigate the effect of CNRIP1 promoter methylation on the proliferative, invasive and migration potential of colorectal cancer cells, including its potential use for the early detection and prognostic assessment of colorectal cancer. Material and methods: Quantitative methylation-specific PCR (qMSP) was used to detect the methylation status of the CNRIP1 promoter region in peripheral blood samples drawn from patients with colorectal adenocarcinoma, benign colorectal adenoma, and matched healthy controls. Putative CpG methylation sites were then pyrosequenced. We subsequently suppressed CNRIP1 methylation within colon cancer cells via treatment with 5 azacytidine and overexpressed colon cancer cells by transfection with a CNRIP1 overexpression pcDNA3.0 plasmid. Thereafter, the CNRIP1 methylation status and mRNA and protein expressions levels were determined. Finally, the proliferative, invasive and migration abilities of cell lines were determined with the CCK-8 and Transwell cell assays. Results: There were differences in the methylation status at loci 2216, 2226, 2231, 2245, and 2254 within the promoter region of CNRIP1 between patients with colorectal adenocarcinoma, colorectal adenoma, and healthy volunteers. The methylation status of CpG sequence 2245 significantly correlated with tumor diameter, invasion depth, TNM stage, grade, and lymph node metastasis (p < 0.05). The proliferative, invasive and migration abilities of colon cancer cells treated with 5-azaC or transfected with a CNRIP1-overexpression plasmid were significantly impaired relative to negative controls (p < 0.05). Conclusions: The methylation status at locus 2245 within the CNRIP1 promoter region has potential value for the early detection and prognostic evaluation of colorectal cancers. Demethylation of the CNRIP1 promoter or overexpression of CNRIP1 can reduce the proliferative and migration abilities of colon cancer cells. PMID- 29181059 TI - Polymorphism of MSH2 Gly322Asp and MLH1 -93G>A in non-familial colon cancer - a case-controlled study. AB - Introduction: Our aim was to determine the effect of the single nucleotide polymorphisms (SNP) -93G>A of the MLH1 gene (rs1800734) and Gly322Asp of the MSH2 gene (rs4987188) on the risk of colon cancer (CC) and identify any relationship with clinical factors. Material and methods: The study included 144 unrelated patients with sporadic CC (71 males; mean age: 61.7 +/-11 years) and 151 control patients (74 males; mean age: 63 +/-11 years). DNA was extracted from peripheral blood lymphocytes, and genotypes were determined by polymerase chain reaction restriction fragment length polymorphism. Results: In our population, the homozygous G/G genotype of the -93G>AMLH1 gene increased the risk of sporadic CC (OR = 2.07; 95% CI: 1.11-3.83; p < 0.02). For A/G and A/A genotypes, the MLH1 93G>A polymorphism was significantly more common in women (p = 0.034). The SNP demonstrated differences in allele distribution according to the location of the tumor, i.e. right vs. left side (p = 0.014), and disease recurrence (p = 0.022). Significant differences were found in the occurrence of Gly322Asp of MSH2 with regard to primary and recurrent disease (p = 0.001). Conclusions: The -93G>AMLH1 polymorphism plays an important role in evaluating the risk of sporadic CC. It can also be used as an indicator in some patients with left-sided and recurrent tumors. MSH2 Gly322Asp is a potential marker in patients with risk of recurrence. PMID- 29181060 TI - Expression of multidrug resistance protein P-glycoprotein in correlation with markers of hypoxia (HIF-1alpha, EPO, EPO-R) in invasive breast cancer with metastasis to lymph nodes. AB - Introduction: Overexpression of the mdr-1 gene is the earliest discovered mechanism of multidrug resistance, which is associated with P-glycoprotein (P-gp) - a cell membrane protein responsible for the efflux of drugs of various structures out of cancer cells. Although the expression of P-glycoprotein has been demonstrated in many cancer types, its relation to markers of hypoxia such as HIF-1alpha, EPO-R or EPO in invasive breast cancer is not well established. The aim of this research was to analyze the co-expression of P-glycoprotein and the markers of tissue hypoxia HIF-1alpha, EPO, and EPO-R by immunohistochemistry in invasive breast cancer classified according to the presence of steroid receptors and the HER2 receptors. Material and methods: Tissue samples were collected from 58 patients with the diagnosis of invasive breast cancer with lymph node metastases. The expression of P-gp, HIF-1alpha, EPO-R and EPO was determined by immunohistochemistry. Results: Of all the invasive breast cancers with lymph node metastases, 15.5% expressed P-gp in cell membrane and tumor blood vessels. In our research, there was a significant positive correlation between HER2-positive tumors that did not express steroid receptors (ER-/PR-/HER2+), and P-gp expression (p = 0.049, r = 0.105). Moreover, there was a significant positive correlation between EPO expression and P-gp (p < 0.001, r = 0.474), and between HIF-1alpha expression and P-gp (p = 0.00475, r = 0.371). Conclusions: We found that HIF-1alpha and EPO expression is significantly associated with P-gp expression in invasive breast cancer with lymph node metastases. An important result of our study is the demonstration of a correlation between P-gp expression and patients with HER2-positive breast tumors that do not express steroid receptors. PMID- 29181061 TI - Up-regulation of the long non-coding RNA RMRP contributes to glioma progression and promotes glioma cell proliferation and invasion. AB - Introduction: Gliomas are the most common malignant tumors of the brain. Long non coding RNAs (lncRNAs) play key regulatory roles in various tumors. In this study, we aimed to determine the expression and biological roles of lncRNA RMRP in glioma. Material and methods: The relative expression level of lncRNA RMRP was determined by quantitative real-time polymerase chain reaction (qRT-PCR) in a total of 39 patients with glioma. RNA interference (RNAi) approaches were used to investigate the biological functions of RMRP. The effect of lncRNA RMRP on proliferation was determined by CCK8 assay. Cell cycle and apoptosis were evaluated by flow cytometry analysis. Cell migration was explored by the wound healing assay. Cell invasion was investigated by the Transwell invasion assay. Results: LncRNA RMRP was up-regulated in human glioma tissues compared with normal brain tissues (p < 0.05). LncRNA RMRP up-regulation was significantly correlated with advanced tumor grade and low Karnofsky Performance Score (KPS) (p < 0.05). Moreover, patients with a high expression level of lncRNA RMRP had a relatively poor prognosis (p < 0.05). Multivariate analyses revealed that lncRNA RMRP expression served as an independent predictor for overall survival of glioma patients (p < 0.05). In addition, inhibition of lncRNA RMRP by RNAi significantly suppressed the proliferation, migration and invasion of glioma cells in vitro (p < 0.05). Conclusions: lncRNA RMRP might act as an oncogene and could be used as a therapeutic target for the treatment of glioma. Our findings provide an in-depth insight into the role of lncRNA RMRP in glioma progression. PMID- 29181062 TI - Investigation of platinum nanoparticle properties against U87 glioblastoma multiforme. AB - Introduction: Gliomas are the most aggressive and common primary tumors of the central nervous system (CNS). Many side effects of drugs containing platinum and their poor penetration of the CNS are major drawbacks in glioma therapy. The aim of the study was to investigate and compare the toxicity of platinum nanoparticles and cisplatin and their anticancer properties in examination with a U87 glioma cell line and tumor. Material and methods: Nanoparticles of platinum (NP-Pt) and cisplatin were incubated with U87 glioma cells or injected directly into tumor tissue. The biological properties of NP-Pt and cisplatin were compared through the morphology, viability, mortality, genotoxicity and the type of cell death of U87 glioma cells, the morphology and ultrastructure of glioma tumor, and expression of caspase-3, p53 and PCNA mRNA. Results: NP-Pt at concentrations of 0.14 uM/ml, 0.29 uM/ml and 0.65 uM/ml had a harmful influence on viability of U87 glioblastoma multiforme (GBM) cells, but also showed genotoxic properties as well as a pro-apoptotic effect on cancer cells. It was found that NP-Pt decreased the weight and volume of U87 GBM tumor tissue and caused pathomorphological changes in the ultrastructure and morphology of tumor tissue, but they also upregulated p53 and caspase-3 mRNA expression. Conclusions: The comparison between the effectiveness of glioblastoma treatment by NP-Pt vs cisplatin showed promising results for future studies. The results indicate that the properties of NP-Pt might be utilized for brain cancer therapy. PMID- 29181063 TI - Impact of connexin 43 coupling on survival and migration of multiple myeloma cells. AB - Introduction: Gap junctions (GJs) represent the best known intercellular communication (IC) system and are membrane-spanning channels that facilitate intercellular communication by allowing small signaling molecules to pass from cell to cell. In this study, we constructed an amino terminus of human Cx43 (Cx43NT-GFP), verified the overexpression of Cx43-NT in HUVEC cells and explored the impact of gap junctions (GJs) on multiple myeloma (MM). Material and methods: The levels of phosphorylated Cx43(s368) and the change of MAPK pathway associated molecules (ERK1/2, JNK, p38, NFkappaB) were also investigated in our cell models. Cx43 mRNA and proteins were detected in both MM cell lines and mesenchymal stem cells (MSCs). Dye transfer assays demonstrated that gap junction intercellular communication (GJIC) occurring via Cx43 situated between MM and MSCs or MM and HUVECCx43NT is functional. Results: Our results present evidence for a channel dependent modulator action of connexin 43 on the migratory activity of MM cells toward MSCs or HUVECCx43-N was higher than those of spontaneous migration (p < 0.05) and protection them from apoptosis in the presence of dexamethasone via cytokines secretion. In the meantime, the migration of MM cells involves an augmented response of p38 and JNK signaling pathway of carboxyl tail of the protein. Conclusions: Our data suggest that GJIC between MM and MSCs is one of the essential factors in tumor cell proliferation and drug sensitivity, and is implicated in MM pathogenesis. PMID- 29181064 TI - Diagnostic investigations of PLA2G16 and CDH11 expression levels as independent prognostic markers of human osteosarcoma. AB - Introduction: The aim of this study was to facilitate and deepen the understanding of the associations of the clinical significance of PLA2G16 and CDH11 in patients with osteosarcoma. Material and methods: We collected 50 paired osteosarcoma tissues and adjacent normal bone tissues and evaluated the expression of PLA2G16 and CDH11 by quantitavise reverse transcriptase real-time polymerase chain reaction. Results: PLA2G16 expression was upregulated in osteosarcoma tissues when compared with adjacent normal bone tissues, and the difference was statistically significant (4.78 +/-0.70 vs. 1.31 +/-0.65; p < 0.05). Our data indicated that high expression of PLA2G16 was significantly related to advanced TNM stage and metastasis or recurrence (p < 0.05). The expression level of CDH11 was lower in osteosarcoma tissues (median relative expression level +/- SD: 6.29 +/-1.43) than adjacent normal bone tissues (mean +/ SD: 13.72 +/-3.08, p < 0.05). Our findings demonstrated that decreased expression of CDH11 was strongly linked to advanced TNM stage, and metastasis or recurrence (p < 0.05). Log-rank analysis showed that patients with high expression of PLA2G16 have shorter overall survival than those with low expression. Moreover, shorter overall survival was significantly correlated with decreased expression of CDH11. Multivariate Cox proportional hazards analysis showed that PLA2G16 (p = 0.028; HR = 2.621; 95% CI) and CDH11 (p = 0.023; HR = 2.81; 95% CI) expression and also metastasis or recurrence (p = 0.03; HR = 2.531; 95% CI) were independent prognostic factors for poor overall survival of osteosarcoma patients. Conclusions: These findings suggest that PLA2G16 and CDH11 expression can be independent prognostic factors for poor overall survival of patients with osteosarcoma. PMID- 29181065 TI - Down-regulation of microRNA-182 and microRNA-183 predicts progression of osteosarcoma. AB - Introduction: The aim of this study was to investigate the expression levels of microRNA-182 and microRNA-183 and their association with clinicopathological features in patients with osteosarcoma. Material and methods: Total RNA was purified from samples and noncancerous bone tissues and then quantitative real time polymerase chain reaction was applied to evaluate the expression levels of microRNAs, and their relationship with clinicopathological features and survival in osteosarcoma patients. Results: Our findings showed that expression of MiR-182 was clearly lower in osteosarcoma bone tissue (mean +/- SD: 2.84 +/-.07) compared with noncancerous bone tissues (6.23 +/-1.72, p = 0.004). On the other hand, lower expression of MiR-183 was seen in osteosarcoma bone tissue (1.43 +/-0.59) when compared with normal tissues (4.36 +/-2.47, p = 0.036). Decreased expression of MiR-182 was clearly correlated with advanced clinical stage (p = 0.001), metastasis or recurrence (p = 0.024), and large tumor size (p = 0.032). Decreased expression of MiR-183 was associated with advanced TNM stage (p = 0.004), and metastasis or recurrence (p = 0.002). A multivariate Cox proportional hazards model revealed that low expression of MiR-182 and MiR-183 (p = 0.02; p = 0.016), TNM stage (p = 0.04), and metastasis or recurrence (p = 0.03) were significantly associated with poor survival as independent prognostic factors. Conclusions: These findings suggest that MiR-182 and MiR-183 may be associated with progression and metastasis of osteosarcoma. PMID- 29181066 TI - Stem cell factor in the serum of patients with esophageal cancer in relation to its histological types. AB - Introduction: Hematopoietic growth factors (HGFs), such as stem cell factor (SCF), may stimulate proliferation and differentiation of hematopoietic progenitor cells. Stem cell factor is also able to affect the growth of malignant tumors, including esophageal cancer (EC). The prognosis of EC patients' survival is still unfavorable. Thus, novel biomarkers are necessary to improve the diagnosis and prognosis of EC patients. The aim of this study was to determine the serum SCF concentrations in EC patients in relation to its histological types and compare these levels with the classical tumor marker - carcinoembryonic antigen (CEA). Material and methods: The study included 56 EC patients and 65 healthy controls. Serum SCF and CEA concentrations were measured using immunoenzyme assays. Moreover, diagnostic criteria of both proteins tested and the survival of EC patients were assessed. Results: The serum SCF concentrations were lower in EC patients compared to healthy controls, but the difference was not significant, whereas CEA levels were higher in EC patients than in healthy subjects. The serum SCF concentrations were significantly higher in patients with adenocarcinoma of the esophagus (AC) than in patients with esophageal squamous cell carcinoma (ESCC). Moreover, the diagnostic sensitivity of SCF (88%) was higher than for CEA (29%) and increased for combined analysis of SCF with CEA. Conclusions: Our findings suggest the potential role of serum SCF in the diagnosis of EC patients, especially in combination with the classical tumor marker. However, due to the non-specific nature of SCF, this issue requires further investigations performed on a larger population of EC patients. PMID- 29181067 TI - Preoperative immunonutrition regulates tumor infiltrative lymphocytes and increases tumor angiogenesis in gastric cancer patients. AB - Introduction: An increased number of tumor infiltrative lymphocytes (TILs) is considered a favorable prognostic factor in various cancers because it is a marker of antitumoral activity of the immune system. In this prospective, non randomized clinical trial, we evaluated the impact of preoperative immunonutrition on tumor infiltrative lymphocytes and neoangiogenesis in cancerous tissue in patients with locoregional and resectable gastric adenocarcinoma. Material and methods: Patients with locoregional and resectable gastric adenocarcinoma were divided non-randomly into two study groups. The first (control) group included patients who had standard nutrition, and the second group included those who had immunonutrition for 7 days before surgery. The biopsy samples taken endoscopically in the preoperative period, as well as the gastrectomy samples, were subjected to immunohistochemical staining for quantitative analysis of CD4, CD8, CD16, CD56, CD31 and CD105 antibodies. Main outcome measures were CD4-to-CD8 ratio and CD105 levels. Results: Fifty patients were included in the study between January 2013 and December 2014. Twenty-five patients were assigned to each of the first and second group. The CD4-to-CD8 ratio and CD105 levels determined in endoscopic biopsy samples were similar in both groups. The CD4-to-CD8 ratio in gastrectomy samples was significantly higher in the first group (p = 0.0001). The CD105 levels in gastrectomy samples were significantly lower in the first group (p = 0.01). Conclusions: Seven-day preoperative immunonutrition use regulates TILs in gastric cancer patients, but prolonged use increases tumor angiogenesis. PMID- 29181068 TI - Immunohistochemical features and staging of early gastric cancer. AB - Introduction: The aim of this study was to analyze the particularities of early gastric cancer (EGC) and their importance for staging, prognosis, and therapy. Material and methods: A total of 338 GCs diagnosed and surgically removed in three medical institutes from Eastern Europe were retrospectively examined, and the EGCs were further examined. Besides the demographic factors and tumor characteristics, immunostains were performed with E-cadherin, HER-2, p53, Ki67, MLH-1, MSH-2, COX-2, VEGF-A, CD31, and CD105. Results: From the 338 GCs, 29 were EGCs, the average being similar in Poland and Hungary (12.37% and 13.33% respectively) but lower in Romania (5.61%). The rate of lymph node metastases was 20.69% (n = 6). Two of the cases presented liver metastases, both of them having a multifocal aspect. In 1 of these cases, limited to the mucosa, intramural carcinomatosis of the lymph vessels was seen in submucosa, muscularis propria, and subserosa. COX-2 positivity was observed in 14 (48.72%) cases. COX-2 was directly correlated with microvessel density determined with CD31 (p < 0.001) and CD105 (p = 0.03). Same correlation with CD31 and CD105 was seen for HER-2 (p = 0.03 and p = 0.0007). The only negative independent prognostic factors for overall survival were tumor localization at the proximal stomach and male gender, regardless of age. Conclusions: In EGCs, intramural carcinomatosis of the lymph vessels and multifocality should be separately described in every surgical pathology report, as indicators of aggressiveness. Microsatellite status, E cadherin, HER-2, p53, and Ki67 do not have prognostic value in EGC, but the highly angiogenic pattern is a possible therapeutic target. PMID- 29181069 TI - Sorafenib combined with hepatectomy in patients with intermediate-stage and advanced hepatocellular carcinoma. AB - Introduction: Guidelines based on the Barcelona Clinic Liver Cancer (BCLC) classification system recommend that hepatic resection should be performed only in patients in BCLC stage A. Patients with stage B or stage C should receive palliative or no treatment. However, actual clinical practice varies, and a recent analysis of hepatocellular carcinoma (HCC) surgery outcomes in high volume surgical centers throughout the world concluded that hepatectomy can provide survival benefit for selected patients in all three BCLC stages. The aim of this study is to evaluate the efficacy and tolerability of adjuvant sorafenib after hepatic resection in patients with intermediate-stage and advanced HCC. Material and methods: In a retrospective case-control study involving 81 patients with intermediate/advanced HCC, 27 who received sorafenib 400 mg BID (median duration 7.33 months) following hepatic resection were compared with a matched group of 54 patients who received hepatic resection only. Overall survival (OS) and time to recurrence (TTR) were evaluated over a median follow-up time of 14.5 months. Results: The median OS was significantly longer in the surgery+sorafenib group than in the surgery-only group (18.6 vs. 11.9 months, respectively; p = 0.014). However, the median TTR did not differ significantly between the 2 groups (p = 0.291). Conclusions: Sorafenib is effective as adjuvant therapy after liver resection in intermediate-stage and advanced HCC, and can be considered a viable treatment option following surgery in such patients. PMID- 29181070 TI - Investigation of clinicopathological parameters in emergency colorectal cancer surgery: a study of 67 patients. AB - Introduction: The aim of the present study was to establish, having adjusted for case mix, the size of the differences in postoperative mortality and 5-year survival between patients presenting as an emergency with evidence of obstruction and perforation and the association of clinicopathological factors with mortality (bivariate analyses). Material and methods: The study included 67 patients who presented with colorectal cancer (CRC) between 2009 and 2013 in Iran. The mean age of the patients was 59.7 years. Of the 67 patients, 37 (55.22%) were male and 30 (44.77%) were female. Certain parameters that correlated with CRC and surgical treatment were investigated. Results: Our results showed that 46 (68.65%) patients had obstruction, while perforation was observed in 21 (31.34%) cases. Among the patients with obstruction, obstruction of the right colon was observed in 29 (43.28%) cases. There was no significant difference in mortality rate between right and left colonic obstruction. Based on the bivariate analyses, our findings showed that death of patients was significantly related to tumor grade (p = 0.02) and TNM staging (p = 0.026), but no association was found between other parameters and death, including age, sex, and tumor site. Conclusions: Compared with patients who undergo elective surgery for colon cancer, those who present as an emergency with evidence of obstruction or perforation have higher postoperative mortality rates and poorer cancer-specific survival. Also, colorectal cancer patients with emergency surgery showed aggressive histopathology and an advanced stage. PMID- 29181071 TI - Application of artificial neural networks for predicting presence of non-sentinel lymph node metastases in breast cancer patients with positive sentinel lymph node biopsies. AB - Introduction: The aim of this study was to present a new predictive tool for non sentinel lymph node (nSLN) metastases. Material and methods: One thousand five hundred eighty-three patients with early-stage breast cancer were subjected to sentinel lymph node biopsy (SLNB) between 2004 and 2012. Metastatic SLNs were found in 348 patients - the retrospective group. Selective axillary lymph node dissection (ALND) was performed in 94% of cases. Involvement of the nSLNs was identified in 32.1% of patients following ALND. The correlation between nSLN involvement and selected epidemiological data, primary tumor features and details of the diagnostic and therapeutic management was examined in metastatic SLN group. Multivariate analysis was performed using an artificial neural network to create a new nomogram. The new test was validated using the overall study population consisting of the prospective group (365 patients - SLNB between 01 07.2013). Results: Accuracy of the new test was calculated using area under the receiver operating characteristics curve (AUC). We obtained AUC coefficient equal to 0.87 (95% confidence interval: 0.81-0.92). Sensitivity amounted to 69%, specificity to 86%, accuracy - 80% (retrospective group) and 77%, 46%, 66% (validation group), respectively. The Memorial Sloan-Kettering Cancer Center (MSKCC) nomogram the calculated AUC value was 0.71, for Stanford - 0.68, for Tenon - 0.67. Conclusions: In the analyzed group only the MSKCC nomogram and the new model showed AUC values exceeding the expected level of 0.70. Our nomogram performs well in prospective validation on patient series. The overall assessment of clinical usefulness of this test will be possible after testing it on different patient populations. PMID- 29181072 TI - Retrospective evaluation of histopathological examinations in invasive ductal breast cancer of no special type: an analysis of 691 patients. AB - Introduction: Invasive ductal carcinoma (IDC) is the most common type of breast cancer in women and accounts for about 80% of all breast cancers. Material and methods: The material consisted of histological preparations derived from 691 patients treated for IDC-NST. Results: In our own study material, invasive ductal breast cancer of no special type accounted for more than 60% of cases, with the largest percentage of tumors being classified as G2 (53.96%) and G3 (28.98%). In terms of tumor size, the most common IDC-NST tumors were those of stage T1c (34.59%) and T2 (35.31%). The incidence of lymph node involvement was also assessed to reveal that no lymph node metastases were present in 45.44% of IDC NST tumors. In the histopathological analysis of IDC-NST, significant statistical correlation was demonstrated between the presence of lymph node metastases and the histological malignancy grade (N0/G1-G3 p = 0.0103; N1A/G1-G3 p = 0.0498; N1B/G1-G3 p< 0.001; N3/G1-G3 p = 0.0027; N4/G1-G3 p < 0.001), between the presence of lymph node metastases and the tumor size (N0/T1-T4 p = 0.00295; N1B/T1-T4 p < 0.001; N2/T1-T4 p < 0.001; N2A/T1-T2 p < 0.001; N4/T1-T4 p < 0.001; Nx/T1-T4 p = 0.0447), as well as between the histological malignancy grade and the tumor size (G1/T1-T4 p < 0.001; G1/2/T1-T4 p < 0.001; G2/3/T1-T4 p < 0.0267). Conclusions: Own research demonstrated that the most common histological type of breast cancer is invasive ductal carcinoma of no special type (IDC-NST); statistically significant correlations were demonstrated in IDC-NST patients between the lymph node involvement status and the histological malignancy grade or tumor size as well as between the histological malignancy grade and the tumor size. PMID- 29181073 TI - One-step nucleic acid amplification analysis of sentinel lymph nodes in papillary thyroid cancer patients. AB - Introduction: It is essential to look for methods to define the need for central lymphadenectomy for papillary thyroid cancer patients. The aim is to determine the efficacy of one-step nucleic acid amplification (OSNA) and sentinel lymph node (SLN) biopsy in the intraoperative detection of nodal involvement. Material and methods: This prospective, experimental study enrolled 49 patients with clinically negative lymph nodes. Intraoperatively, 1% Patent Blue dye was injected intratumorally. Lymph nodes that stained blue were defined as SLNs. They were directly cut into blocks at 2-mm intervals. Nonadjacent blocks were subjected to either the OSNA assay or histological examination. Results: Sixty five SLNs were found in 43 (87.8%) patients. There were 20 (30.8%) histopathologically positive SLNs. According to the OSNA, 22 (33.8%) SLNs were positive. The OSNA results were different from histopathology in 8 (12.3%) SLNs. The OSNA gave a positive result in 5 (7.7%) SLNs, while they were not involved according to the histopathology. However, OSNA upstaged N status from N0 to N1 only in 2 (3.1%) patients. Inverse results (histopathology +, OSNA-) were obtained in 3 (4.6%) SLNs. Positive and negative predictive values (PPV and NPV) for OSNA were 0.77 and 0.93, respectively. The concordance rate between examinations was 85.5%. Conclusions: In some patients with clinically negative lymph nodes, OSNA and SLN biopsy may prevent unnecessary central lymphadenectomy. On the other hand, the sentinel lymph node biopsy may reveal the presence of potentially involved sentinel lymph nodes outside the central compartment. These SLNs can also be assessed by means of OSNA. PMID- 29181074 TI - Hindgut neuroendocrine neoplasms - characteristics and prognosis. AB - Introduction: The aim of the study was to analyze the clinicopathologic characteristics and prognostic factors of hindgut-rectal neuroendocrine neoplasms. Material and methods: The study included 38 patients with rectal neuroendocrine tumors who were treated at the Department of Endocrinology, Metabolism and Internal Diseases, Poznan University of Medical Sciences, Poznan, Poland from February 2010 to December 2015. The clinicopathological data were retrospectively reviewed, extracted, analyzed, and patients were followed up to determine their survival status. Follow-up data were available for all 38 patients. Uni- and multivariate Cox regression analyses were performed to determine the prognostic factors significantly associated with overall survival. Results: The tumors occurred mostly in the middle and lower rectum, and the most typical symptoms experienced by patients were hematochezia and diarrhea. The median distance between the tumors and the anal edges was 4.7 +/-1.3 cm, and the median diameter of the tumors was 0.9 +/-1.2 cm. The major pathological types were neuroendocrine neoplasm G1 in 31 patients, and neuroendocrine neoplasm G2 in 7 patients. Tumor-node-metastasis (TNM) stages I, II, III and IV tumors accounted for 76.3% (29/38), 5.3% (2/38), 7.9% (3/38) and 10.5% (4/38) of patients, respectively. The main treatment method was transanal extended excision or endoscopic resection. The 1-, 3- and 5-year survival rates of the whole group of patients were 100%, 83.7%, and 75.3%, respectively. Conclusions: Univariate analysis showed that age (p = 0.022), tumor diameter (p < 0.001), histological type (p < 0.001), and TNM stage (p < 0.001) were all prognostic factors. PMID- 29181076 TI - Intensive rehabilitation as an independent determinant of better outcome in patients with lung tumors treated by thoracic surgery. AB - Introduction: The frequency of postoperative complications after thoracic surgery remains high. Rehabilitation may become a procedure characterized by a high cost effectiveness ratio. The aim of the study was to determine the independent importance of intensive rehabilitation in patients with lung tumors treated by thoracic surgery. Material and methods: The prospective observational study included two groups of patients: 187 patients treated according to the historical scheme including thoracic surgery without specific exercises improving cardio pulmonary capacity, and 215 patients treated in agreement with the innovative algorithm of perioperative intensive physiotherapy until discharge from hospital. The evaluated clinical endpoints comprised bronchoscopy for pulmonary toilet and all other possible postoperative complications. Results: The use of intensive physiotherapy significantly shortened the duration of hospitalization through reducing the frequencies of different postoperative complications. The specific clinical benefit was associated with a significantly lower rate of bronchoscopy performance for pulmonary toilet (16% vs. 5.6%, p = 0.0006). Multivariate regression analyses revealed intensive physiotherapy as a significant independent predictor for all postoperative complications (OR = 0.57; 95% CI: 0.323-0.988; p = 0.045) and need to perform bronchoscopy for pulmonary toilet (OR = 0.24; 95% CI: 0.11-0.51; p = 0.0002). Conclusions: The study showed the strong independent positive effect of intensive rehabilitation in patients with lung tumors treated by thoracic surgery. PMID- 29181075 TI - MGMT promoter methylation as a potential prognostic marker for acute leukemia. AB - Introduction: It has been proved that genetic and epigenetic changes play a significant role in the development and progression of acute leukemia. The aim of our study was to evaluate the frequency and prognostic implications of genetic and epigenetic alterations in p15, MGMT, DNMT3A and TP53 genes in acute leukemias. Material and methods: We included in the study 59 patients with acute leukemia. Evaluation of TP53 and DNMT3A mutations was performed using sequencing analysis and PCR-RFLP, respectively. Methylation status of MGMT and p15 genes was evaluated using MSP and COBRA, respectively. For assessment of global DNA methylation ELISA-based kit was used. Results: We found that overall survival was higher for ALL patients. MGMT promoter methylation was significantly associated with patients age at the time of diagnosis (p = 0.03). TP53 and DNMT3A mutations were observed only in AML patients (16.67% and 8.8%, respectively). Patients with acute leukemia and p15 promoter methylation had significantly more frequently mutated TP53 gene (p = 0.04) and AML patients with p15 promoter methylation had significantly more frequently detected global hypomethylation of DNA (p = 0.009). In the group of ALL patients we noted an opposite trend: only patients negative for p15 promoter methylation were characterized by global DNA hypomethylation. Conclusions: Our findings demonstrate that MGMT promoter methylation can have a considerable impact on the development of acute leukemia in older patients. DNMT3A and TP53 mutations may play a significant role in AML development. However, further studies conducted in a larger cohort of patients are needed to determine its clinical utility. PMID- 29181077 TI - Updated analysis of vitamin D receptor gene FokI polymorphism and prostate cancer susceptibility. AB - Introduction: Polymorphisms of the vitamin D receptor (VDR) gene have been investigated in various case-control studies to evaluate prostate cancer susceptibility; however, published data on the association between vitamin D receptor gene FokI polymorphism and prostate cancer risk are inconclusive. Material and methods: To assess the impact of vitamin D receptor gene FokI polymorphism, we performed a meta-analysis of eligible studies including 9,720 patients and 9,710 control subjects. Results: The overall results indicated no obvious association of this variant on prostate cancer risk. However, in subgroup analysis by ethnicity, positive associations existed in Caucasian descendents for allelic contrast (OR = 1.03, 95% CI: 1.00-1.06, pheterogeneity = 0.552, p = 0.026) and the dominant genetic model (OR = 1.03, 95% CI: 1.00-1.05, pheterogeneity = 0.856, p = 0.032). In the subgroup analysis by tumor stage, there was a significant association between this variant and advanced prostate cancer under the recessive genetic model (OR = 1.15, 95% CI: 1.01-1.32, pheterogeneity = 0.469, p = 0.032). In the subgroup analysis by source of control, association of the VDR FokI polymorphism and prostate cancer susceptibility was also found in population-based studies under homozygote comparison and the recessive genetic model. Conclusions: The VDR FokI polymorphism may contribute to the risk of developing prostate cancer in Caucasian and population-based studies. Further large, well-designed studies are warranted to confirm this conclusion in more detail. PMID- 29181078 TI - Pain, acceptance of illness, adjustment to life with cancer and coping strategies in prostate cancer patients. AB - Introduction: Prostate cancer is the second most common type of carcinoma in men. The rate of prostate cancer has increased approximately fivefold lover the last 30 years. The purpose of the study was to evaluate coping strategies, pain management, illness acceptance, and adjustment to cancer in patients diagnosed with prostate carcinoma and the effect of socioeconomic variables on the above mentioned issues. Material and methods: The study included 228 patients diagnosed with prostate cancer. The questionnaire interview consisted of demographic questions and four psychometric tests: BPCQ, measuring the influence of factors affecting pain management, CSQ, designed to evaluate pain coping strategies, the AIS questionnaire, measuring disease acceptance, and the Mini-Mac. Results: Pain locus of control scores in prostate cancer patients are distributed evenly across all three BPCQ subscales. The top mean score was observed in the area of beliefs that powerful others (doctors) control pain. Increased behavioral activity was the most frequently selected coping strategy (mean score = 18.27). The average level of disease acceptance in study patients was 30.39, with a standard deviation of 8.07. The results were differentiated by education (p = 0.08) and income (p = 0.012). The most frequently indicated coping strategies were fighting spirit (mean score = 22.46) and positive re-evaluation (mean score = 22.04). Conclusions: The main belief about pain control in prostate cancer patients is that powerful others (doctors) control pain. The study patients cope with disease constructively. The main socioeconomic variables which differentiate the scores obtained across all tests are income and education. PMID- 29181079 TI - Survivin expression, HPV positivity and microvessel density in oropharyngeal carcinomas and relationship with survival time. AB - Introduction: Among head and neck cancers, those of the oral cavity and oropharynx are the second most prevalent following the larynx. This study aimed to research immunohistochemical expression of survivin, HPV positivity and microvessel density in tumors and their relationships with prognosis. Material and methods: Pathological materials and demographic properties of 46 patients were retrospectively evaluated. Survivin, HPV and CD34 (for microvessel density evaluation) antibodies were applied tumoral tissues. Survival times, clinical stage and differentiation were evaluated. Results: In univariate analysis, we observed that survivin, microvessel density and stage were significantly associated with survival time (p < 0.05). In multivariate analysis, only survivin and microvessel density were associated with survival time (p < 0.05). But we did not find significant correlation between neither tumor differentiation nor HPV positivity and survival (p > 0.05). Conclusions: Survivin levels and microvessel density were found to be effective prognostic factors and were related to survival in oral cavity and oropharyngeal cancers. Treatments targeting survivin expression and angiogenesis might be employed against these tumor groups. PMID- 29181080 TI - Quality of life of patients from rural and urban areas in Poland with head and neck cancer treated with radiotherapy. A study of the influence of selected socio demographic factors. AB - Introduction: The quality of life (QoL) experienced by cancer patients depends both on their state of health and on sociodemographic factors. Tumours in the head and neck region have a particularly adverse effect on patients psychologically and on their social functioning. Material and methods: The study involved 121 patients receiving radiotherapy treatment for head and neck cancers. They included 72 urban and 49 rural residents. QoL was assessed using the questionnaires EORTC-QLQ-C30 and QLQ-H&N35. The data were analysed using statistical methods: a chi2 test for independence and a multinomial logit model. Results: The evaluation of QoL showed a strong, statistically significant, positive dependence on state of health, and a weak dependence on sociodemographic factors and place of residence. Evaluations of financial situation and living conditions were similar for rural and urban residents. Patients from urban areas had the greatest anxiety about deterioration of their state of health. Rural respondents were more often anxious about a worsening of their financial situation, and expressed a fear of loneliness. Conclusions: Studying the QoL of patients with head and neck cancer provides information concerning the areas in which the disease inhibits their lives, and the extent to which it does so. It indicates conditions for the adaptation of treatment and care methods in the healthcare system which might improve the QoL of such patients. A multinomial logit model identifies the factors determining the patients' health assessment and defines the probable values of such assessment. PMID- 29181081 TI - Care of cancer patients with liver and bone metastases - the place of pharmaceutical care in a balanced plan, focused on the patient's needs and goals. AB - Metastatic cancer, especially in the growing population of geriatric patients, presents a big challenge to these patients, as well as to treatment teams and the entire health care system. This article describes some common medical problems faced by patients with metastases to liver and bone, and presents a diagnostic approach, and therapeutic management of various symptoms, relevant to advanced stages of the malignant disease. The article highlights the importance of patient education on various aspects of metastatic cancer, and underscores the unique position of pharmacists practicing pharmaceutical care, which is particularly beneficial in this group of patients with advanced malignancy. Also, this paper emphasizes that achieving a proper balance between managing the malignant disease and maintaining the patients' quality of life, especially in the elderly population, should involve coordinated efforts of the oncology treatment team, primary care physicians, pharmacists, therapists and nurses, as well as patients, their families and caregivers.

AB - Melanoma is one of the most dangerous and lethal skin cancers, with a considerable metastatic potential and drug resistance. It involves a malignant transformation of melanocytes. The exact course of events in which melanocytes become melanoma cells remains unclear. Nevertheless, this process is said to be dependent on the occurrence of cells with the phenotype of progenitor cells - cells characterized by expression of proteins such as nestin, CD-133 or CD-271. The development of these cells and their survival were found to be potentially dependent on the neural crest stem cell transcription factor SOX10. This is just one of the possible roles of SOX10, which contributes to melanomagenesis by regulating the SOX10-MITF pathway, but also to melanoma cell survival, proliferation and metastasis formation. The aim of this review is to describe the broad influence of the SOX10-MITF pathway on melanoma cells. PMID- 29181084 TI - Clinical pharmacogenomics: patient perspectives of pharmacogenomic testing and the incidence of actionable test results in a chronic disease cohort. AB - Aim: This study aimed to examine pharmacogenomic test results and patient perspectives at an academic cardiovascular medicine clinic. Patients & methods: Test results for three common cardiovascular drug-gene tests (warfarin-CYP2C9 VKORC1, clopidogrel-CYP2C19 and simvastatin-SLCO1B1) of 208 patients in the Ohio State University-Coriell Personalized Medicine Collaborative were examined to determine the incidence of potentially actionable test results. A post-hoc, anonymous, patient survey was also conducted. Results: Potentially actionable test results for at least one of the three drug-gene tests were determined in 170 (82%) patients. Survey responses (n = 134) suggested that patients generally considered their test results to be important (median of 7.5 on a 10-point scale of importance) and were interested (median of 7.3 on a 10-point scale of interest) in a Clinical Pharmacogenomic Service. Conclusion: Attitudes toward pharmacogenomic testing were generally favorable, and potentially actionable test results were not uncommon in this cardiovascular medicine cohort. PMID- 29181085 TI - Communication challenges for nongeneticist physicians relaying clinical genomic results. AB - Aim: Identify the behavioral challenges to the use of genome sequencing (GS) in a clinical setting. Materials & methods: We observed how general internists and nongenetic specialists delivered GS results to patients enrolled in the MedSeq Project. Using transcripts of such disclosure interactions, we made qualitative observations of communication behaviors that could limit the usefulness of GS results until reaching the point of thematic saturation. Results: Findings included confusion regarding genomic terminology, difficulty with the volume or complexity of information and difficulties communicating complex risk information to patients. We observed a broad dismissal of clinical value of GS by some physicians and sometimes ineffective communication regarding health behavior change. Conclusion: Overcoming these behavioral challenges is necessary to make full use of clinical GS results. PMID- 29181087 TI - Deep Convolutional Neural Networks for Classifying Body Constitution Based on Face Image. AB - Body constitution classification is the basis and core content of traditional Chinese medicine constitution research. It is to extract the relevant laws from the complex constitution phenomenon and finally build the constitution classification system. Traditional identification methods have the disadvantages of inefficiency and low accuracy, for instance, questionnaires. This paper proposed a body constitution recognition algorithm based on deep convolutional neural network, which can classify individual constitution types according to face images. The proposed model first uses the convolutional neural network to extract the features of face image and then combines the extracted features with the color features. Finally, the fusion features are input to the Softmax classifier to get the classification result. Different comparison experiments show that the algorithm proposed in this paper can achieve the accuracy of 65.29% about the constitution classification. And its performance was accepted by Chinese medicine practitioners. PMID- 29181089 TI - Are we enabling the next generation to thrive? PMID- 29181086 TI - Recent advances in the development of antiviral therapeutics for Rift Valley fever virus infection. AB - Rift Valley fever virus (RVFV) is a mosquito-borne bunyavirus endemic to sub Saharan Africa and the Arabian Peninsula and the etiological agent of Rift Valley fever. Rift Valley fever is a disease of major public health and economic concern, affecting livestock and humans. In ruminants, RVFV infection is characterized by high mortality rates in newborns and near 100% abortion rates in pregnant animals. Infection in humans is typically manifested as a self-limiting febrile illness, but can lead to severe and fatal hepatitis, encephalitis, hemorrhagic fever or retinitis with partial or complete blindness. Currently, there are no specific treatment options available for RVFV infection. This review presents a summary of the therapeutic approaches that have been explored on the treatment of RVFV infection. PMID- 29181088 TI - Improving detection of mental health problems in community settings in Nepal: development and pilot testing of the community informant detection tool. AB - Background: Despite increasing efforts to expand availability of mental health services throughout the world, there continues to be limited utilization of these services by persons with mental illness and their families. Community-based detection that facilitates identification and referral of people with mental health problems has been advocated as an effective strategy to increase help seeking and service utilization. The Community Informant Detection Tool (CIDT) was developed for the community informants to identify people with depression, psychosis, alcohol use problems, epilepsy, and child behavioral problems in community settings. The CIDT has been validated in Nepal and found to be effective in promoting treatment initiation. To facilitate replication in other settings, this paper describes the development process of CIDT and the steps to achieve comprehensibility, utility and feasibility. Methods: The CIDT was developed in four steps. First, case vignettes and illustrations were created incorporating local idioms of distress for symptoms of each disorder with an expert panel of 25 Nepali mental health professionals. Second, the utility of a draft tool was assessed through focus group discussions (n = 19) and in-depth interviews (n = 6). Third, a practice run was conducted assessing applicability of the tool through IDI among purposively selected community informants (n = 8). Finally, surveys were administered to 105 community informants to assess feasibility. Results: The first through third steps led to modifications in the format and presentation of the CIDT. The pilot test found CIDT to be comprehensible and feasible for detection and referral of all conditions except child behavioral problems. Female community health volunteers were recommended as the most appropriate persons to utilize the CIDT. Conclusion: Community-based detection using the CIDT for persons in need of mental health care is perceived to be useful and feasible by key community stakeholders who would integrate the tool into their daily activities. PMID- 29181090 TI - Beginner's mind. AB - : The concept of 'beginner's mind' invites the expert medical professional to be present to their patients, remaining curious and responsive in the face of the individuality of illness. Each patient is a universe of unknowns, presenting with suffering which cannot always be classified with a diagnosis. Improvisation and openness may not just benefit our patients enduring their patient journeys but may also revive and reconnect us with our own humanity. Why this matters to me: My experience as cancer patient brought home to me the value of encountering a doctor who was present and able to listen and respond to me as an individual. It did not necessarily take longer, but was about an attitude of heart.Like any professional, as GPs we are at risk of presumption and habitual thinking. Beginner's mind, that is recapturing the openness and curiosity modelled to us by children, can powerfully transform the medical encounter, allowing space for emergence of patient perspective and doctor response. Key message: Embrace curiosity and learning into our expert clinical practice. PMID- 29181091 TI - Parenting and child mental health. AB - : This paper reviews parenting programmes and their effectiveness with families of young children and highlights additional resources for primary care practitioners. Typically, 30% of GP consultations concern child behaviour problems and established behaviour problems can have lasting effects on children's life chances. These problems can be identified in infancy and toddlerhood.Parenting is a key risk factor in their development and maintenance, yet is also amenable to change. In this paper we consider six parenting programmes that are widely evaluated and/or available in the U.K. and their evidence base . These include two NICE recommended parenting programmes (Incredible Years and Triple P), which offer tiered and flexible parenting programmes; predominantly for parents of school-age children. We also review Parent-Infant Psychotherapy, which is typically for parents of younger children. Fourth is Family Nurse Partnership, an intensive programme to support young, first-time mothers. Finally we consider, video feedback programmes which use video to focus in detail on parents' interactions with their children, including Video Feedback to Promote Positive Parenting and Video Interactive Guidance. These interventions demonstrate the range of approaches which are being used to intervene early in children's lives to try to prevent the development of enduring behavioural problems. Why this matters to me: It is becoming increasingly clear that the origins of many mental health problems lie in childhood. Family factors, including the quality of care that parents provide for their children, can make a huge difference to children's early life pathways, for better or for worse. Understanding how best to intervene to support parents is a key challenge. In this article, we critically review the most widely used parenting programmes for parents of young children. It is imperative that we judge these early interventions to high standards so that we are offering children the best start in life. Key message: Parenting programmes offer a means to intercept behaviour problems in early childhood before they become established. PMID- 29181092 TI - Efficacy of multisystemic therapy in youths aged 10-17 with severe antisocial behaviour and emotional disorders: systematic review. AB - Background: Antisocial behaviour and conduct disorders are the most common behavioural and mental health problems in children and young people globally. An efficacious intervention is needed to manage these antisocial behaviours that have costly consequences. Multisystemic Therapy (MST), an intensive home-based intervention for youths with psychosocial and behavioural problems, is recommended under National Institute for Health and Clinical Excellence guidelines for conduct disorder. However, reviews on the efficacy of MST are mixed. Aim: To review randomised controlled trials (RCTs) reporting efficacy of MST among youths presenting with antisocial behaviour and emotional disorder respectively. Method: A systematic map term to subject heading search was conducted in PsycINFO, Embase, and Ovid Medline databases for articles up to November 2015. RCTs comparing MST vs.treatment as usual (TAU) in youths presenting with antisocial behaviour and emotional disorder were included. Results: 12 RCTs (n = 1425) reported efficacy of MST vs. TAU in youths presenting with antisocial behaviour and emotional disorder. Clinically significant treatment effects of MST showed a reduction of antisocial behaviour which includes delinquency. MST, vs. psychiatric hospitalisation, was associated with a reduction of suicidal attempts in youths presenting with psychiatric emergencies. 4 studies showed that MST was less costly than TAU in the short term, with further analysis required for long-term cost-effectiveness. Conclusion: MST is an efficacious intervention for severe antisocial behaviours in reduction of delinquency and should be included in clinical practices. MST was shown to have a positive effect on emotional disorder but further research is needed to evaluate the efficacy of MST with emotional disorder. Further analysis is required to assess the services utilized for long-term cost effectiveness.

AB - Interactive and multimedia methods are the future, already developing in teaching and learning modules in Medicine. It happens and has to happen because: 1) It improves tools for the teacher in preparing and showing the bulk of materials on which students must study and learn; it enables interactivity with learners both in formative pathway and in final assessment. 2) It improves attention, interest and involvement of students and learners, and acts as a guideline to progressive broadening in researches, studies, considerations, and information exchanges among different learners. 3) The rapid progress in application of technology, WEB area and sources researches allows such a deepening and widening interactivity that before was never possible to imagine. It is the same thing also in CME, sometimes so dry, and dropped from above, while the new methodology may/must get rid of negative and boring features, often not useful in producing particular improvements in knowledge and quality. The Professional Doctor needs to feel a protagonist part in situation to be investigated, where interaction with all what media tools can offer may produce an "educative" improvement, much faster, effective and pleasant/rewarding. PMID- 29181095 TI - Quantitation of Fentanyl Analogs in Dried Blood Spots by Flow-Through Desorption Coupled to Online Solid Phase Extraction Tandem Mass Spectrometry. AB - An automated dried blood spot (DBS) elution coupled with solid phase extraction and tandem mass spectrometric analysis for multiple fentanyl analogs was developed and assessed. This method confirms human exposures to fentanyl, sufentanil, carfentanil, alfentanil, lofentanil, alpha-methyl fentanyl, and 3 methyl fentanyl in blood with minimal sample volume and reduced shipping and storage costs. Seven fentanyl analogs were detected and quantitated from DBS made from venous blood. The calibration curve in matrix was linear in the concentration range of 1.0 ng/mL to 100 ng/mL with a correlation coefficient greater than 0.98 for all compounds. The limit of detection varied from 0.15 ng/mL to 0.66 ng/mL depending on target analyte. Analysis of the entire DBS minimized the effects of hematocrit on quantitation. All quality control materials evaluated resulted in <15% error; analytes with isotopically labeled internal standards had <15% RSD, while analytes without matching standards had 15 24% RSD. This method provides an automated means to detect seven fentanyl analogs, and quantitate four fentanyl analogs with the benefits of DBS at levels anticipated from an overdose of these potent opioids. PMID- 29181096 TI - Structure Activity Relationship of Heparin Mimicking Polymer p(SS-co-PEGMA): Effect of Sulfonation and Polymer Size on FGF2-Receptor Binding. AB - Fibroblast growth factor-2 (FGF2) is a heparin binding protein that plays a role in a range of biological functions such as wound healing and bone regeneration. Heparin, a highly sulfated glycosaminoglycan, is required for FGF2 to bind to its receptor. Therefore, polymeric mimics of heparin are widely studied for their ability to manipulate FGF2-induced biological interactions. It is known that altering the degree of sulfonated monomer incorporation and size of heparin mimicking polymers can affect protein-receptor binding. To elucidate the relationship between degree of sulfonation and receptor binding for the heparin mimicking polymer, poly(styrene sulfonate-co-poly(ethylene glycol) methyl ether methacrylate) (p(SS-co-PEGMA)) a library was synthesized to contain nine polymers with degrees of sulfonation ranging from 0-100%. Kinetics of the polymerization was evaluated and reactivity ratios compared to literature results. These polymers were then tested for their ability to enhance FGF2 binding with its receptor as both covalent conjugates and as excipients. In a receptor based enzyme-linked immunosorbant assay (ELISA), as well as a cell-based study, the polymer with 81% SS incorporation enhanced receptor binding compared to FGF2 alone, and to a greater extent than the other polymers. Therefore, another library of polymers was prepared maintaining the degree of sulfonation at 81% and changing the size from 41 to 390 monomer repeat units. The polymers were again tested in receptor based ELISA and cell studies, and all of the different sizes performed similarly, except for degree of polymerization 295 and 390, which had reduced response in the cellular assay. These results provide important information for the use of pSS-co-PEGMA as a potential heparin-mimicking therapeutic. PMID- 29181097 TI - Stomatin-like protein 2 is overexpressed in cervical cancer and involved in tumor cell apoptosis. AB - Stomatin-like protein 2 (SLP-2) is overexpressed in numerous types of human cancer and previous studies revealed that SLP-2 may function in mitochondria. The purpose of the present study was to evaluate the expression of SLP-2 in cervical cancer and the association between SLP-2 expression and clinical features, in addition to investigating the role of SLP-2 in the apoptosis of cervical cancer cells. The expression profile of SLP-2 was determined by quantitative polymerase chain reaction, western blotting and immunohistochemical staining. The effect of SLP-2 on cell apoptosis induced by chemotherapeutics in cervical cancer cells was evaluated using Annexin V staining and terminal deoxynucleotidyl-transferase mediated dUTP nick end labeling (TUNEL) assays. The results indicated that SLP-2 expression in cervical cancer was significantly upregulated at the mRNA and protein levels, compared with that in normal cervical tissues. Immunohistochemical analysis revealed significant correlation between SLP-2 protein expression and clinical characteristics, including the squamous cell carcinoma antigen (P=0.003), deep stromal invasion (P=0.021), lymphovascular space involvement (P=0.044) and pelvic lymph node metastasis (P<0.001), which served as independent prognostic factors for predicting the shortening of overall survival time in patients with early-stage cervical cancer. In addition, TUNEL and Annexin V binding assays revealed that silencing SLP-2 expression significantly enhanced the sensitivity of cervical cancer cells to apoptosis induced by chemotherapeutics. Taken together, the results of the present study suggest that SLP-2 may be a progressive gene in the development of cervical cancer. Overexpression of SLP-2 serves an important role in the apoptosis of human cervical cancer cells.

AB - A subset of cells, termed side-population (SP), which have the ability to efflux Hoeschst 33342, have previously been demonstrated to act as a potential method to isolate stem cells. Numerous stem/progenitor cells have been localized in different regions of the mouse hair follicle (HF). The present study identified a SP in the mouse HF expressing the ABCG2 transporter and MTS24 surface marker. These cells are restricted to the upper isthmus of the HF and have previously been described as progenitor cells. Consistent with their SP characteristic, they demonstrated elevated expression of ABCG2 transporter, which participates in the dye efflux. Analysis of tumor epidermal cell lines revealed a correlation between the number of SP keratinocytes and the grade of malignancy, suggesting that the SP may play a role in malignant progression. Consistent with this idea, the present study observed an increased number of cells expressing ABCG2 and MTS24 in chemically induced skin tumors and skin tumor cell lines. This SP does not express the CD34 surface marker detected in the multipotent stem cells of the bulge region of the HF, which have been defined as tumor initiation cells. The present study concluded that a SP with properties of progenitor cells is localized in the upper isthmus of the HF and is important in mouse skin tumor progression. PMID- 29181099 TI - Breast cancers with EGFR and HER2 co-amplification favor distant metastasis and poor clinical outcome. AB - ErbB signaling serves essential roles in invasive ductal carcinoma (IDC). The aim of the present study was to assess gene amplification in ErbB family members in IDC with clinical implications. Quantitative polymerase chain reaction and fluorescence in situ hybridization were performed on formalin-fixed paraffin embedded tumor samples for gene amplification detection. The clinical and histopathological characteristics, as well as the prognostic significance, were analyzed. Among the 119 IDC patients evaluated, epidermal growth factor receptor [EGFR; also known as human epidermal growth factor receptor (HER)1], HER2, HER3 and HER4 gene amplification was observed in 30 (25.2%), 44 (36.9%), 0 (0.0%) and 1 (0.8%) patients, respectively. EGFR amplification was associated with estrogen receptor status (P=0.028) and higher possibilities of recurrence (P=0.015) and distant metastasis (following initial surgery) (P=0.011). In survival analysis, EGFR amplification was also associated with disease-free survival (DFS) (P=0.001) and overall survival (OS) (P=0.003). HER2 amplification was associated with larger tumor size (P=0.006), later clinical stage (P=0.003) and distant metastasis (following initial surgery) (P=0.006). In survival analysis, HER2 amplification was also associated with DFS (P=0.011). Notably, the present study identified a group of patients in whom EGFR and HER2 were co-amplified. This group of patients appeared to have a higher possibility of metastasis (when diagnosed) (P=0.014) and distant metastasis (following initial surgery) (P<0.001). In survival analysis, these patients were noticed to be associated with DFS (P<0.001) and OS (P=0.002). With respect to treatment regimen, this was also true for the DFS association with chemotherapy (P<0.001), radiotherapy (P<0.001) and hormonal therapy (P=0.001). The present results suggest that EGFR and HER2 amplification favor distant metastasis following initial surgery and are significantly associated with poor clinical outcome in breast cancer patients. PMID- 29181100 TI - Kinesin family member 11 contributes to the progression and prognosis of human breast cancer. AB - The present study aimed to clarify the association between kinesin family member 11 (KIF11) and human breast cancer, and the effect of KIF11 on breast cancer cell progression. Western blot analysis, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis, retroviral infection, immunohistochemistry staining, MTT assay, anchorage-independent growth ability assay and tumorigenicity assay were all used in the present study. Western blot and RT-qPCR analysis revealed that the expression of KIF11 was markedly increased in malignant cells compared with that in non-tumorous cells at the mRNA and protein level. Immunohistochemical analysis revealed that KIF11 expression was upregulated in 256/268 (95.8%) paraffin-embedded archival breast cancer biopsies. Statistical analysis demonstrated a significant association between the upregulation of KIF11 expression and the progression of breast cancer. Multivariate analysis revealed that KIF11 upregulation represents an independent prognostic indicator for the survival of patients with breast cancer. Tumorigenicity experiments were further used to evaluate the effect of KIF11 in non-obese diabetic/severe combined immunodeficient mice. Silencing endogenous KIF11 by short hairpin RNAs inhibited the proliferation of breast cancer cells in vitro and in vivo. The present results suggest that KIF11 may serve an important function in the proliferation of breast cancer and may represent a novel and useful prognostic marker for breast cancer. PMID- 29181101 TI - Downregulation of nuclear and cytoplasmic Chibby is associated with advanced cervical cancer. AB - Chibby has been identified as a putative tumor suppressor and antagonist to beta catenin, thereby controlling the Wnt signaling pathway. Chibby is typically downregulated in numerous types of cancer and may be associated with tumorigenesis. The present study aimed at clarifying the following: i) Whether Chibby antagonizes beta-catenin in cervical cancer; ii) whether Chibby and beta catenin mRNA expression is associated with cancer progression; and iii) whether Chibby and beta-catenin expression may be used as a biomarker. A total of 87 paraffin-embedded cervical sections with distinct cervical intraepithelial neoplasia (CIN) stages (chronic cervicitis, CIN 1, CIN 2, CIN 3 and invasive squamous cell carcinoma) were collected between June 2004 and October 2012 The mRNA expression level of Chibby and beta-catenin was determined using the polymerase chain reaction. Protein expression and cellular localization of Chibby and beta-catenin were determined using immunohistochemistry. Chibby and beta catenin were analyzed for possible association with the progression of cervical cancer. Chibby mRNA expression and the Chibby/beta-catenin ratio were identified to be downregulated in invasive tumors. Positive cytoplasmic and nuclear staining for Chibby was associated with CIN staging and decreased as the CIN stage increased. In addition, the cytoplasmic and membrane intensity of beta-catenin was associated with invasive tumors, in which a significantly increased level of protein expression was detected. Chibby may be a tumor suppressor in cervical cancer, since the dysregulation of Chibby expression is associated with tumorigenesis in cervical cancer. Chibby and beta-catenin expression together may potentially to a biomarker for disease progression in cervical cancer. PMID- 29181102 TI - MicroRNA-1271 inhibits cellular proliferation of hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is one of the most common causes of cancer associated mortality worldwide, particularly in China. MicroRNAs (miRs) serve important roles in the pathogenesis of HCC. The present study investigated the function of miR-1271 in HCC. The miR-1271 levels were analyzed by quantitative reverse transcription polymerase chain reaction. Cells growth was examined by MTT assay. Bioinformatics algorithms from TargetScanHuman were used to predict the target genes of miR-1271. The protein level was assayed by western blotting. miR 1271 demonstrated a lower expression level in HCC tissues. Upregulation of miR 1271 suppressed the growth of HepG-2 and Huh-7 cells and induced apoptosis of cells. Forkhead box Q1 (FOXQ1) was targeted by miR-1271. In conclusion, miR-1271 is a novel tumor suppressor that inhibits HCC proliferation and induces cellular apoptosis by targeting FOXQ1 in HCC. The results of the present study may provide a novel therapeutic target of HCC. PMID- 29181103 TI - Myxoid liposarcoma with cartilaginous differentiation showing DDIT3 rearrangement. AB - Myxoid liposarcoma (MLPS) is the second most common histologic subtype of liposarcoma. However, cartilaginous differentiation within MLPS is an extremely rare phenomenon, with only 7 cases of MLPS with cartilaginous differentiation reported to date. The majority of MLPS cases show the t(12;16)(q13;p11) translocation, resulting in the fused in sarcoma-DNA damage-inducible transcript 3 (FUS-DDIT3) fusion gene. This fusion gene as a hallmark of MLPS is very useful for differential diagnosis from other soft tissue sarcomas, and the associated protein, FUS-DDIT3, performs an important role in the phenotypic selection of targeted multipotent mesenchymal cells during oncogenesis. In this report, a case of MLPS with cartilaginous differentiation that occurred in the thigh of a 44 year-old woman is described. Histopathologically, the tumor was composed of a typical myxoid liposarcoma area and a mature hyaline cartilaginous area. Using fluorescence in situ hybridization analysis, rearrangement of the DDIT3 gene was detected in not only the liposarcomatous area but also in the chondrocytes of the cartilaginous area. Based on these findings, the cartilaginous differentiation area appears to be partially associated with oncogenesis through the specific fusion gene FUS-DDIT3. PMID- 29181104 TI - Recombinant human adenovirus-p53 improves the outcome of mid-late stage pancreatic cancer via arterial infusion. AB - The present study aimed to investigate the therapeutic efficacy and clinical value of recombinant human adenovirus-p53 (rAd-p53) perfusion via the pancreatic artery for the treatment of mid-late stage pancreatic cancer. rAd-p53 (2*1012 virus particles) in 6 ml normal saline was pushed (intravenous bolus) into the gastroduodenal and superior pancreaticoduodenal arteries via interventional superselection, with the catheter retained for subsequent drug administration at a 3-day interval for 4 cycles. Tumor changes in all patients were observed to evaluate tumor response by computed tomography (CT) at 2, 8 and 16 weeks post treatment. The following improvements were noted in the 23-patient cohort: A total of 73.9% (17/23) of patients demonstrated significant tumor shrinkage (>20%); the symptoms of abdominal and back pain were relieved in 15 patients; the survival time was >12 months in 1 patient and >6 months in 14 patients; the patient's general condition, including appetite, was improved in 13 patients; body weight was increased in 9 patients; jaundice was attenuated in 12 patients; and ascites subsided in 10 patients. However, the therapeutic outcome was poor in 2 patients whose tumors size did not show significant change after treatment as detected by CT. These 2 patients succumbed within 6 months. In conclusion, rAd p53 perfusion via the pancreatic artery is a safe and minimally invasive option for the treatment of mid-late stage pancreatic cancer. PMID- 29181105 TI - Overexpression of long non-coding RNA colon cancer-associated transcript 2 is associated with advanced tumor progression and poor prognosis in patients with colorectal cancer. AB - The aim of the present study was to explore the clinicopathological and prognostic significance of long non-coding RNA (lncRNA) colon cancer-associated transcript 2 (CCAT2) expression in human colorectal cancer (CRC). Expression levels of lncRNA CCAT2 in CRC, adjacent non-tumor and healthy colon mucosa tissues were detected by quantitative polymerase chain reaction. The disease-free survival and overall survival rates were evaluated using the Kaplan-Meier method, and multivariate analysis was performed using Cox proportional hazard analysis. The expression level of lncRNA CCAT2 in CRC tissues was increased significantly compared with adjacent normal tissues or non-cancerous tissues. CCAT2 expression was observed to be progressively increased between tumor-node-metastasis (TNM) stages I and IV. A high level of CCAT2 expression was revealed to be associated with poor cell differentiation, deeper tumor infiltration, lymph node metastasis, distance metastasis, vascular invasion and advanced TNM stage. Compared with patients with low levels of CCAT2 expression, patients with high levels of CCAT2 expression had shorter disease-free survival and overall survival times. Multivariate analyses indicated that high CCAT2 expression was an independent poor prognostic factor. Therefore, increased lncRNA CCAT2 expression maybe a potential diagnostic biomarker for CRC, and an independent predictor of prognosis in patients with CRC. PMID- 29181106 TI - ALDH enzyme activity is regulated by Nodal and histamine in the A549 cell line. AB - The present study aimed to examine whether the enzyme activity of aldehyde dehydrogenase (ALDH) was regulated by Nodal and histamine in the human alveolar adenocarcinoma A549 cell line. The regulated enzyme activity of ALDH was analyzed by flow cytometry in the A549 cell line. ALDH1 and Nodal expression was investigated by immunohistochemistry in28 cases of lung mixed adenocarcinoma. The enzyme activity of ALDH was upregulated by histamine and agonists of histamine H1 receptor (H1R) and histamine H2 receptor (H2R). ALDH activity was also downregulated by recombinant human Nodal and antagonists of H1R and H2R in the A549 cell line. In addition, expression of Nodal and ALDH1 were inversely correlated in lung mixed adenocarcinoma. ALDH enzyme activity was regulated by Nodal and histamine in lung adenocarcinoma. PMID- 29181108 TI - Comparative profiling of well-defined copper reagents and precursors for the trifluoromethylation of aryl iodides. AB - A number of copper reagents were compared for their effectiveness in trifluoromethylating 4-iodobiphenyl, 4-iodotoluene, and 2-iodotoluene. Yields over time were plotted in order to refine our understanding of each reagent performance, identify any bottlenecks, and provide more insight into the rates of the reactions. Interestingly, differences in reactivity were observed when a well defined [LCuCF3] complex was employed directly or generated in situ from precursors by published reports. Relative reactivities were also found to highly dependent on the nature of the iodoarenes. PMID- 29181107 TI - Investigation of fusion gene expression in HCT116 cells. AB - Colon cancer is the most common type of gastrointestinal cancer. A number of specific and sensitive biomarkers facilitate the diagnosis and monitoring of patients with colon cancer. Fusion genes are typically identified in cancer and a majority of the newly identified fusion genes are oncogenic in nature. Therefore, fusion genes are potential biomarkers and/or therapy targets in cancer. In the present study, the regulation of specific candidate fusion genes were investigated using Brother of the Regulator of Imprinted Sites (BORIS) in the HCT116 colon cancer cell line, which is a paralog of the fusion gene regulator CCCTC-binding factor (CTCF). The copy number of BORIS increased correspondingly to the progression of colorectal carcinoma from the M0 to the M1a stage. It was identified that EIF3E(e1)-RSPO2(e2), EIF3E(e1)-RSPO2(e3), PTPRK(e1)-RSPO3(e2), PTPRK(e7)-RSPO3(e2), TADA2A-MEF2B and MED13L-CD4 are fusion transcripts present in the transcriptome of the HCT116 colon cancer cell line. CDC42SE2-KIAAO146 is a genomic fusion transcript, which originates from DNA arrangement in HCT116 cells. BORIS suppresses the expression of EIF3E, RSPO2, PTPRK, RSPO3, TADA2A and CD4 to inhibit the expression of fusion transcripts in HCT116 cells. It was hypothesized that the fusion transcripts investigated in the present study may not be oncogenic in HCT116 cells. As BORIS is not colorectal carcinoma-specific, the fusion genes investigated may be a biomarker assemblage for monitoring the progression of colorectal carcinoma.

AB - The parent benzophospholo[3,2-b]indole was prepared by the reaction of dichlorophenylphosphine with a dilithium intermediate, which was prepared in two steps from 2-ethynyl-N,N-dimethylaniline. Using the obtained benzophosphole-fused indole as a common starting material, simple modifications were carried out at the phosphorus center of the phosphole, synthesizing various functionalized analogs. The X-ray structure analysis of trivalent phosphole and phosphine oxide showed that the fused tetracyclic moieties are planar. The benzophosphole-fused indoles, such as phosphine oxide, phospholium salt, and borane complex, exhibited strong photoluminescence in dichloromethane (Phi = 67-75%).

AB - The synthesis of diosgenyl 2-amino-2-deoxy-beta-D-galactopyranoside is presented for the first time. This synthetic saponin was transformed into its hydrochloride as well as N-acyl, 2-ureido, N-alkyl, and N,N-dialkyl derivatives. Antifungal and antibacterial studies show that some of the obtained compounds are active against Gram-positive bacteria and Candida type fungi.

AB - Backbone-extended amino acids have a variety of potential applications in peptide and protein science, particularly if the geometry of the amino acid is controllable. Here we describe the synthesis of delta-amino acids that contain three vicinal C-F bonds positioned along the backbone. The ultimately successful synthetic approach emerged through the investigation of several methods based on both electrophilic and nucleophilic fluorination chemistry. We show that different diastereoisomers of this fluorinated delta-amino acid adopt distinct conformations in solution, suggesting that these molecules might have value as shape-controlled building blocks for future applications in peptide science.

AB - Herein, we present a new strategy for the preparation of a broad range of brassinosteroid biosynthetic precursors/metabolites differing by the ring A fragment. The protocol is based on the use of readily available phytohormones of this class bearing a 2alpha,3alpha-diol moiety (epibrassinolide or epicastasterone) as starting materials. The required functionalities (Delta2-, 2alpha,3alpha- and 2beta,3beta-epoxy-, 2alpha,3beta-, 2beta,3alpha-, and 2beta,3beta-dihydroxy-, 3-keto-, 3alpha- and 3beta-hydroxy-, 2alpha-hydroxy-3 keto-) were synthesized from 2alpha,3alpha-diols in a few simple steps (Corey Winter reaction, epoxidation, oxidation, hydride reduction, etc.). PMID- 29181113 TI - Is the tungsten(IV) complex (NEt4)2[WO(mnt)2] a functional analogue of acetylene hydratase? AB - The tungsten(IV) complex (Et4N)2[W(O)(mnt)2] (1; mnt = maleonitriledithiolate) was proposed (Sarkar et al., J. Am. Chem. Soc.1997, 119, 4315) to be a functional analogue of the active center of the enzyme acetylene hydratase from Pelobacter acetylenicus, which hydrates acetylene (ethyne; 2) to acetaldehyde (ethanal; 3). In the absence of a satisfactory mechanistic proposal for the hydration reaction, we considered the possibility of a metal-vinylidene type activation mode, as it is well established for ruthenium-based alkyne hydration catalysts with anti Markovnikov regioselectivity. To validate the hypothesis, the regioselectivity of tungsten-catalyzed alkyne hydration of a terminal, higher alkyne had to be determined. However, complex 1 was not a competent catalyst for the hydration of 1-octyne under the conditions tested. Furthermore, we could not observe the earlier reported hydration activity of complex 1 towards acetylene. A critical assessment of, and a possible explanation for the earlier reported results are offered. The title question is answered with "no".

AB - In situ activation of 3-arylpropiolic acids with T3P(r) (n-propylphosphonic acid anhydride) initiates a domino reaction furnishing 4-arylnaphtho[2,3-c]furan-1,3 diones in excellent yields. Upon employing these anhydrides as reactive intermediates blue-luminescent 4-aryl-1H-benzo[f]isoindole-1,3(2H)-diones are formed by consecutive pseudo three-component syntheses in a one-pot fashion. The Stokes shifts correlate excellently with the Hammett-Taft sigmaR parameter indicating an extended degree of resonance stabilization in the vibrationally relaxed excited singlet state. PMID- 29181115 TI - Solvent-free copper-catalyzed click chemistry for the synthesis of N-heterocyclic hybrids based on quinoline and 1,2,3-triazole. AB - Copper-catalyzed mechanochemical click reactions using Cu(II), Cu(I) and Cu(0) catalysts have been successfully implemented to provide novel 6-phenyl-2 (trifluoromethyl)quinolines with a phenyl-1,2,3-triazole moiety at O-4 of the quinoline core. Milling procedures proved to be significantly more efficient than the corresponding solution reactions, with up to a 15-fold gain in yield. Efficiency of both solution and milling procedures depended on the p-substituent in the azide reactant, resulting in H < Cl < Br < I reactivity bias. Solid-state catalysis using Cu(II) and Cu(I) catalysts entailed the direct involvement of the copper species in the reaction and generation of highly luminescent compounds which hindered in situ monitoring by Raman spectroscopy. However, in situ monitoring of the milling processes was enabled by using Cu(0) catalysts in the form of brass milling media which offered a direct insight into the reaction pathway of mechanochemical CuAAC reactions, indicating that the catalysis is most likely conducted on the surface of milling balls. Electron spin resonance spectroscopy was used to determine the oxidation and spin states of the respective copper catalysts in bulk products obtained by milling procedures.

AB - Nine new quadrupolar chromophores based on diketopyrrolopyrrole were designed and prepared by cross-coupling reactions. The property tuning has been achieved by structural variation of the peripheral substituents (donor) and enlargement of the pi-system. Fundamental properties of target molecules were studied by differential scanning calorimetry, electrochemistry, and absorption and emission spectra. Nonlinear optical properties were studied by measuring the third harmonic generation. The experimental data were completed by quantum-chemical calculations and structure-property relationships were elucidated. PMID- 29181119 TI - Electron-deficient pyridinium salts/thiourea cooperative catalyzed O glycosylation via activation of O-glycosyl trichloroacetimidate donors. AB - The glycosylation of O-glycosyl trichloroacetimidate donors using a synergistic catalytic system of electron-deficient pyridinium salts/aryl thiourea derivatives at room temperature is demonstrated. The acidity of the adduct formed by the 1,2 addition of alcohol to the electron-deficient pyridinium salt is increased in the presence of an aryl thiourea derivative as an hydrogen-bonding cocatalyst. This transformation occurs under mild reaction conditions with a wide range of O glycosyl trichloroacetimidate donors and glycosyl acceptors to afford the corresponding O-glycosides in moderate to good yields with predictable selectivity. In addition, the optimized method is also utilized for the regioselective O-glycosylation by using a partially protected acceptor. PMID- 29181120 TI - Synthesis, effect of substituents on the regiochemistry and equilibrium studies of tetrazolo[1,5-a]pyrimidine/2-azidopyrimidines. AB - An efficient synthesis methodology for a series of tetrazolo[1,5-a]pyrimidines substituted at the 5- and 7-positions from the cyclocondensation reaction [CCC + NCN] was developed. The NCN corresponds to 5-aminotetrazole and CCC to beta enaminone. Two distinct products were observed in accordance with the beta enaminone substituent. When observed in solution, the compounds can be divided into two groups: (a) precursor compounds with R = CF3 or CCl3, which leads to tetrazolo[1,5-a]pyrimidines in high regioselectivity with R at the 7-position of the heterocyclic ring; and (b) precursor compounds with R = aryl or methyl, which leads to a mixture of compounds, tetrazolo[1,5-a] pyrimidines (R in the 5 position of the ring) and 2-azidopyrimidines (R in the 4-position of the ring), which was attributed to an equilibrium of azide-tetrazole. In the solid state, all compounds were found as 2-azidopyrimidines. The regiochemistry of the reaction and the stability of the products are discussed on the basis of the data obtained by density functional theory (DFT) for energetic and molecular orbital (MO) calculations. PMID- 29181121 TI - Ginger Oleoresin Alleviated gamma-Ray Irradiation-Induced Reactive Oxygen Species via the Nrf2 Protective Response in Human Mesenchymal Stem Cells. AB - Unplanned exposure to radiation can cause side effects on high-risk individuals; meanwhile, radiotherapies can also cause injury on normal cells and tissues surrounding the tumor. Besides the direct radiation damage, most of the ionizing radiation- (IR-) induced injuries were caused by generation of reactive oxygen species (ROS). Human mesenchymal stem cells (hMSCs), which possess self-renew and multilineage differentiation capabilities, are a critical population of cells to participate in the regeneration of IR-damaged tissues. Therefore, it is imperative to search effective radioprotectors for hMSCs. This study was to demonstrate whether natural source ginger oleoresin would mitigate IR-induced injuries in human mesenchymal stem cells (hMSCs). We demonstrated that ginger oleoresin could significantly reduce IR-induced cytotoxicity, ROS generation, and DNA strand breaks. In addition, the ROS-scavenging mechanism of ginger oleoresin was also investigated. The results showed that ginger oleoresin could induce the translocation of Nrf2 to cell nucleus and activate the expression of cytoprotective genes encoding for HO-1 and NQO-1. It suggests that ginger oleoresin has a potential role of being an effective antioxidant and radioprotective agent. PMID- 29181123 TI - Carlina vulgaris L. as a Source of Phytochemicals with Antioxidant Activity. AB - The methanol extracts from three populations of Carlina vulgaris L. were examined for the chlorogenic acid content, mineral content, total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activity. Two populations originated from natural nonmetallicolous habitats (NN (populations from Nasilow) and NP (populations from Pinczow)), and one metallicolous population (MB) was collected from Boleslaw waste heap localized at the place of former open-cast mining of Ag-Pb and Zn-Pb ores dating back to the 13th century and 18th century, respectively. The level of Zn, Pb, Cd, Fe, Ni, and Mn was significantly higher in the root and leaves of MB plants as a result of soil contaminations compared to those of the NN and NP ones. The highest antioxidant potency has been showed by the plants growing in a nonmetallicolous habitat. The flower head extracts obtained from the nonmetallicolous populations also contained the largest amount of chlorogenic acid, whereas the lowest was determined in the roots (ca. 2-3.5 mg/g and 0.2-0.4 mg/g of air-dry weight, resp.). These studies provide important information on the influence of a habitat on the quality of herbal materials and the content of the biologically active primary and secondary metabolites. PMID- 29181124 TI - Inhibition of Caveolae Contributes to Propofol Preconditioning-Suppressed Microvesicles Release and Cell Injury by Hypoxia-Reoxygenation. AB - Endothelial microvesicles (EMVs), released after endothelial cell (EC) apoptosis or activation, may carry many adverse signals and propagate injury by intercellular transmission. Caveolae are 50-100 nm cell surface plasma membrane invaginations involved in many pathophysiological processes. Recent evidence has indicated EMVs and caveolae may have functional effects in cells undergoing H/R injury. Propofol, a widely used anaesthetic, confers antioxidative stress capability in the same process. But the connection between EMVs, H/R, and caveolae remains largely unclear. Here, we found that H/R significantly increased the release of EMVs, the expression of CAV-1 (the structural protein responsible for maintaining the shape of caveolae), oxidative stress, and the mitochondrial damage, and all these changes were inhibited by propofol preconditioning. Interestingly, the caveolae inhibitor Mbeta-CD strengthened the protective effect of propofol preconditioning. We further found that the release of EMVs is more significantly reduced under propofol preconditioning in the presence of the caveolae inhibitor Mbeta-CD. EMVs released from H/R-treated cells caused a substantially increased mitochondrial and cellular damage to normal HUVECs after 4 hours of coculture. Thus, we conclude that inhibition of caveolae contributes to propofol preconditioning-suppressed microvesicles release and cell injury by H/R. PMID- 29181122 TI - Oxidative Stress and Cellular Response to Doxorubicin: A Common Factor in the Complex Milieu of Anthracycline Cardiotoxicity. AB - The production of reactive species is a core of the redox cycling profile of anthracyclines. However, these molecular characteristics can be viewed as a double-edged sword acting not only on neoplastic cells but also on multiple cellular targets throughout the body. This phenomenon translates into anthracycline cardiotoxicity that is a serious problem in the growing population of paediatric and adult cancer survivors. Therefore, better understanding of cellular processes that operate within but also go beyond cardiomyocytes is a necessary step to develop more effective tools for the prevention and treatment of progressive and often severe cardiomyopathy experienced by otherwise successfully treated oncologic patients. In this review, we focus on oxidative stress-triggered cellular events such as DNA damage, senescence, and cell death implicated in anthracycline cardiovascular toxicity. The involvement of progenitor cells of cardiac and extracardiac origin as well as different cardiac cell types is discussed, pointing to molecular signals that impact on cell longevity and functional competence. PMID- 29181125 TI - Protective Effects and Possible Mechanisms of Ergothioneine and Hispidin against Methylglyoxal-Induced Injuries in Rat Pheochromocytoma Cells. AB - Diabetic encephalopathy (DE) is often a complication in patients with Alzheimer's disease due to high blood sugar induced by diabetic mellitus. Ergothioneine (EGT) and hispidin (HIP) are antioxidants present in Phellinus linteus. Methylglyoxal (MGO), a toxic precursor of advanced glycated end products (AGEs), is responsible for protein glycation. We investigated whether a combination EGT and HIP (EGT + HIP) protects against MGO-induced neuronal cell damage. Rat pheochromocytoma (PC12) cells were preincubated with EGT (2 MUM), HIP (2 MUM), or EGT + HIP, then challenged with MGO under high-glucose condition (30 MUM MGO + 30 mM glucose; GLU + MGO) for 24-96 h. GLU + MGO markedly increased protein carbonyls and reactive oxygen species in PC12 cells; both of these levels were strongly reduced by EGT or HIP with effects comparable to those of 100 nM aminoguanidine (an AGE inhibitor) but stronger than those of 10 MUM epalrestat (an aldose reductase inhibitor). GLU + MGO significantly increased the levels of AGE and AGE receptor (RAGE) protein expression of nuclear factor kappa-B (NF-kappaB) in the cytosol, but treatment with EGT, HIP, or EGT + HIP significantly attenuated these levels. These results suggest that EGT and HIP protect against hyperglycemic damage in PC12 cells by inhibiting the NF-kappaB transcription pathway through antioxidant activities.

AB - Neuroinflammation plays a central role in the pathophysiology of Alzheimer's disease (AD). Compounds that suppress neuroinflammation have been identified as potential therapeutic targets for AD. Rhinacanthin C (RC), a naphthoquinone ester found in Rhinacanthus nasutus Kurz (Acanthaceae), is currently proposed as an effective molecule against inflammation. However, the exact role of RC on neuroinflammation remains to be elucidated. In the present study, we investigated RC effect on modulating lipopolysaccharides (LPS), amyloid-beta peptide (Abeta), or interferon-gamma- (IFN-gamma-) evoked pathological events in neurons and glia. Our findings demonstrated that RC prevented Abeta-induced toxicity in rat hippocampal neurons and attenuated LPS-activated nitric oxide (NO) production, inducible nitric oxide synthase (iNOS) expression, and NF-kappaB signaling in rat glia. Likewise, RC suppressed LPS-induced neuroinflammation by reducing NO production and iNOS, IL-1beta, CCL-2, and CCL-5 mRNA levels in rat microglia. Further studies using BV-2 microglia revealed that RC inhibited LPS-, Abeta-, and IFN-gamma-stimulated IL-6 and TNF-alpha secretion. Of note, NF-kappaB and ERK activation was abrogated by RC in BV-2 cell response to Abeta or IFN-gamma. Moreover, RC protected neurons from Abeta-stimulated microglial conditioned media dependent toxicity. Collectively, these data highlight the beneficial effects of RC on neuroprotection and support the therapeutic implications of RC to neuroinflammation-mediated conditions. PMID- 29181127 TI - Oxidative Modification of Blood Serum Proteins in Multiple Sclerosis after Interferon Beta and Melatonin Treatment. AB - Multiple sclerosis (MS) is a disease involving oxidative stress (OS). This study was aimed at examination of the effect of melatonin supplementation on OS parameters, especially oxidative protein modifications of blood serum proteins, in MS patients. The study included 11 control subjects, 14 de novo diagnosed MS patients with the relapsing-remitting form of MS (RRMS), 36 patients with RRMS receiving interferon beta-1b (250 MUg every other day), and 25 RRMS patients receiving interferon beta-1b plus melatonin (5 mg daily). The levels of N' formylkynurenine, kynurenine, dityrosine, carbonyl groups, advanced glycation products (AGEs), advanced oxidation protein products (AOPP), and malondialdehyde were elevated in nontreated RRSM patients. N'-Formylkynurenine, kynurenine, AGEs, and carbonyl contents were decreased only in the group treated with interferon beta plus melatonin, while dityrosine and AOPP contents were decreased both in the group of patients treated with interferon beta and in the group treated with interferon beta-1b plus melatonin. These results demonstrate that melatonin ameliorates OS in MS patients supporting the view that combined administration of interferon beta-1b and melatonin can be more effective in reducing OS in MS patients than interferon beta-1b alone. PMID- 29181128 TI - Telomere shortening in non-tumorous and tumor mucosa is independently related to colorectal carcinogenesis in precancerous lesions. AB - Telomere shortening is associated with colorectal carcinogenesis and recent studies have focused on its characteristics in both normal mucosa and tumor tissues. To clarify the role of telomeres in colorectal carcinogenesis, we analyzed telomere shortening in normal and tumor regions of 93 colorectal precursor lesions. Telomere length was examined in 61 tubular adenomas (TAs) and 32 serrated polyps (SPs), and PIK3CA expression, KRAS mutation, BRAF mutation, and MSI were also analyzed. Telomere length was similar in normal and tumor tissues of TAs and SPs. In normal tissues of TAs, telomere shortening was associated with PIK3CA amplification (81.3% vs. 18.8%, p < 0.001), whereas it was associated with BRAF mutation in normal tissues of SPs (66.7% vs. 23.1%, p = 0.060). According to the analysis on tumor tissues, KRAS and BRAF mutations were mutually exclusive in TAs and SPs (p < 0.001), and telomere shortening was associated with mitochondrial microsatellite instability (63.6% vs. 36.4%, p = 0.030). These data suggested a pivotal role of telomere shortening in normal colorectal tissue for proceeding to TAs or SPs along with PIK3CA amplification and BRAF mutation, respectively. Moreover, telomeres in TAs may collaborate with mitochondrial instability for disease progression.

AB - Nerve sheath myxoma is a rare benign tumor of the peripheral nerves. It typically presents as a painless, firm, and slow growing nodule with a predilection for extremities mostly fingers and knees. Microscopically, it has characteristic multilobules of spindle cells in an abundant myxoid stroma. The cells are strongly positive for S-100 protein. However, this rare tumor is usually misdiagnosed as other more common benign neuronal tumors. This report describes a rare case of nerve sheath myxoma involving the palmar surface of a 23-year-old female. Clinically, it was diagnosed as a fibroma. It was excised and the final diagnosis was made after histopathological and comprehensive immunohistochemical examination of the specimen. The clinicopathological features of this rare tumor and its important differential diagnoses are discussed along with a brief review of the literature. PMID- 29181131 TI - Pressure Sore at an Unusual Site- the Bilateral Popliteal Fossa: A Case report. AB - Pressure sore is tissue ulceration due to unrelieved pressure, altered sensory perception, and exposure to moisture. Geriatric patients with organic problems and patients with spinal cord injuries are the high-risk groups. Soft tissues over bony prominences are the common sites for ulcer development. About 95% of pressure ulcers occur in the lower part of the body. Ischial tuberosity, greater trochanter, sacrum and heel are common sites. In addition to these, pressure sores at unusual sites like nasal alae, malar eminences, cervical region and medial side of knee have also been described. Only 1.6% of the patients present with sores in areas outside the pelvis and lower extremity. In a paraplegic patient, pressure sores are usually over extensor surface of knee and heel but pressure ulcer over popliteal fossa are extremely rare. We herein report a case of a 36-years-old diabetic and paraplegic male, who presented with multiple bed sores involving the sacral area, heels and bilateral popliteal fossa. Popliteal fossa is an unusual site for pressure sores. Only one similar case has been previously reported in the literature. PMID- 29181132 TI - Giant Cell Fibroblastoma: A Case Report. AB - Giant cell fibroblastoma is a rare intermediate grade soft tissue tumor of childhood which characteristically occurs in males during the first decade of life. It has high incidence of local recurrence but metastasis has never been reported. Giant cell fibroblastoma merits attentive interpretation as they have been misdiagnosed as sarcoma in the past leading to erroneous remedies. Here we are reporting a case of giant cell fibroblastoma in a 3-year-old boy who presented with a painless swelling over the medial aspect of right ankle forthe last five months. PMID- 29181133 TI - Use of dark chocolate for diabetic patients: a review of the literature and current evidence. AB - Dietary changes are a major lifestyle factor that can influence the progression of chronic diseases such as diabetes. Recently, flavanols, a subgroup of plant derived phytochemicals called flavonoids, have gained increasing attention, due to studies showing an inverse correlation between dietary intake of flavanols and incidence of diabetes. Flavanoids in the cocoa plant may ameliorate insulin resistance by improving endothelial function, altering glucose metabolism, and reducing oxidative stress. Oxidative stress has been proposed as the main culprit for insulin resistance. The well-established effects of cocoa on endothelial function also points to a possible effect on insulin sensitivity. The relationship between insulin resistance and endothelial function is a reciprocal one. Overall, the evidence from these studies suggests that cocoa may be useful in slowing the progression to type 2 diabetes and ameliorating insulin resistance in metabolic syndrome. Additionally, results from several small studies indicate that cocoa may also have therapeutic potential in preventing cardiovascular complications in diabetic patients. Studies highlighting the potential of cocoa containing diets, in large-randomized controlled trials should be performed which might give us a better opportunity to analyze the potential health-care benefit for reducing the risk of complications in diabetic patients at molecular level. PMID- 29181134 TI - A nine-month-old-boy with Atypical Hemophagocytic Lymphohistiocytosis. AB - Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening hyperinflammation caused by uncontrolled proliferation of activated lymphocytes and histiocytes. Often, HLH is an acquired syndrome. We report a case of a nine month-old-boy presented with hepatosplenomegaly, severe anemia, thrombocytopenia, hypertriglyceridemia and high hyperferritinemia. These clinical features of HLH prompted a wide range of infectious and auto-immune tests to be performed. After an extensive diagnostic workup, he was referred to the immune-hematologic unit for HLH suspicion with an unknown cause. Primary HLH due to familial lymphohistiocytosis (FLH) was first evoked in front of consanguinity, probable HLH in the family, early onset, and in the absence of a causative pathology like infection or cancer. However, functional tests were normal. Atypical features like the: absence of fever, hypotonia, recurrent diarrhea since diversification, hematuria, and proteinuria suggested an inborn metabolism error with gastrointestinal involvement. Specific tests were performed to reach a final diagnosis.

AB - Antithyroid drugs can be a rare cause of agranulocytosis (0.5% of treated patients). Suspension of these drugs is mandatory in these patients and may result in worsening hyperthyroidism. We report the case of a 27-year-old woman who is 3 months post-partum, breastfeeding, and suffering with Graves' disease hyperthyroidism treated first with methimazole and then with propylthiouracil due to a methimazole allergy. She was admitted for urosepsis and agranulocytosis. The patient was diagnosed with propylthiouracil related agranulocytosis, diffuse toxic goiter and thyro-gastric syndrome. Antithyroid drug therapy was stopped resulting in a worsening of thyrotoxicosis. Agranulocytosis was treated with 8 doses of G-CSF with full recovery. To rapidly restore euthyroidism and to perform a thyroidectomy, the patient received 6 therapeutic plasma exchange (TPE) procedures, to clear thyroid hormones and anti-TSH receptor antibodies from blood, resulting in a pre-surgical euthyroid state without antithyroid drug therapy. Two years after thyroidectomy, the patient is well under thyroid hormone replacement therapy with a normal granulocyte count. PMID- 29181136 TI - Feasibility and Effectiveness of Tuberculosis Active Case-Finding among Children Living with Tuberculosis Relatives: a Cross-Sectional Study in Guinea-Bissau. AB - Background and objectives: The World Health Organization End tuberculosis (TB) Strategy, approved in 2014, aims at a 90% reduction in TB deaths and an 80% reduction in TB incidence rate by 2030. One of the suggested interventions is the systematic screening of people with suspected TB, belonging to specific risk groups. The Hospital Raoul Follereau (HRF) in Bissau, Guinea-Bissau, is the National Reference Hospital for Tuberculosis and Lung Disease of the country. We performed an active case-finding program among pediatric age family members and cohabitants of admitted adult TB patients, from January to December 2013. Methods: Newly admitted adult patients with a diagnosis of TB were invited to bring their family members or cohabitants in childhood age for clinical evaluation in a dedicated outpatient setting within the hospital compound. All the children brought to our attention underwent a medical examination and chest x ray. In children with clinical and/or radiologic finding consistent with pulmonary TB, a sputum-smear was requested. Results: All admitted adult patients accepted to bring their children cohabitants. In total, 287 children were examined in 2013. Forty-four patients (15%) were diagnosed with TB. The number needed to screen (NNS) to detect one case of TB was 7. 35 patients (80%) had pulmonary TB; 2 of them were sputum smear-positive. No adjunctive personnel cost was necessary for the intervention. Conclusions: A hospital-based TB active case finding program targeted to high-risk groups like children households of severely ill admitted patients with TB can successfully be implemented in a country with limited resources. PMID- 29181137 TI - Transfusion-Related Acute Lung Injury (TRALI) in two Thalassaemia Patients Caused by the Same Multiparous Blood Donor. AB - We report two separate episodes of transfusion-related acute lung injury (TRALI) in two thalassaemia patients who received red blood cell transfusions from the same multiparous donor. Both cases had the same symptomatology and occurred within 60 minutes of transfusion. The patients presented dyspnoea, sweating, fatigue, dizziness, fever, and sense of losing consciousness. The chest x-ray showed a pulmonary oedema-like picture with both lungs filled with fluid. The patients were treated in the intensive therapy unit. They were weaned off the ventilator and discharged following hospitalization 7 and 9 days respectively. The TRALI syndrome was diagnosed to be associated with HLA-specific donor antibodies against mismatched HLA-antigens of the transfused patients. Haemovigilance improvements are essential for reducing the morbidity and mortality in transfused patients. Blood from multiparous donors should be tested for the presence of IgG HLA-Class I and -Class II antibodies before being transfused in thalassaemia and other chronically transfused patients. PMID- 29181138 TI - Bing-Neel Syndrome: Illustrative Cases and Comprehensive Review of the Literature. AB - The Bing-Neel syndrome is a rare neurological complication of Waldenstrom's Macroglobulinemia which results from a direct involvement of central nervous system by malignant lymphoplasmacytic cells. The clinical suspicion of Bing-Neel syndrome may be overlooked because neurologic symptoms are heterogeneous, nonspecific and sometimes underhand. A definitive diagnosis of Bing-Neel syndrome can be confidently made using brain and spinal cord magnetic resonance imaging as well as histopathology and/or cerebrospinal fluid analysis to confirm the neoplastic infiltration of central nervous system. The detection in the cerebrospinal fluid of patients with Bing-Neel syndrome of the MYD88 (L265P) somatic mutation, which is highly recurrent in Waldenstrom's Macroglobulinemia, proved useful for the diagnosis and monitoring of central nervous system involvement. Despite recommendations recently published, there is still no clear consensus on treatment of Bing-Neel syndrome, which includes systemic immunochemotherapy, intrathecal chemotherapy and brain irradiation as possible options. Ibrutinib, a Bruton kinase inhibitor approved for Waldenstrom's Macroglobulinemia, has been recently added to the therapeutic armamentarium of Bing-Neel syndrome due to its ability to pass the blood-brain barrier. However, prospective clinical trials are eagerly awaited with the aim to define the optimal treatment strategy. Here we describe four illustrative cases of Bing-Neel syndrome diagnosed and treated at our Institution and review the literature on this topic. PMID- 29181139 TI - Outcome of Frontline Treatment with "Generic" Imatinib In Adult Patients with Chronic Myeloid Leukemia in Algerian Population: A Multicenter Study. AB - Introduction: In a developing country like Algeria, such expensive therapy is not available. Alternative approaches are needed to help these adult. In Algeria 'imatib' (CIPLA-India) was introduced in 2006; but no study has been published yet in the North Africa region regarding response and outcome of this copy in CML patients. The goal of this multicenter study is to characterize newly adult CML in the western region of Algeria and to assess the effectiveness and safety of imatib (IM, copy) as frontline therapy for patients with CML. Patients and Methods: The study was carried out in 7 hematology centers in the western Algeria. Patients, who were diagnosed to be suffering from CML between January 1st, 2007 and December 31st, 2014 were selected for data analysis. All patients received a copy preparation, consisting of the alpha crystal form of imatinib, (IM, copy) at an oral dose of 400 mg daily and monitored for tolerance and side effects while on therapy. Results: Between January 2007 and December 2014, 355 patients with CML were treated with imatib (Copy). The median follow- up of the study was 46 months (range: 13-107 months). Complete hematological response (CHR) was seen in 83% of patients within 3 months. According to the Sokal score, 72% patients with low, 78% with intermediate and 69% with high risk disease achieved a CHR in 3 months (p=0.26) and according to the EUTOS score, 81% of patients with low and 70% with high risk disease achieved a CHR in 3 months (p=0.08). The major molecular response (MMR) at six months (M6), M9, M12, M18 and M24 was 21%, 38%, 35%, 51% and 67% respectively and 34% of patients achieved a complete molecular response (CMR). The projected 5-year overall survival (OS) rate was 83%. Side effects of imatib (copy) in this study were similar to those reported previously for the entire imatinib mesylate treatment study and only 8% of patients were intolerant to imatib (copy) and treated with a second generation of BCR-ABL inhibitor. Conclusion: This study reflects real world experience treating patients with CML in a developing country and thus sheds light on differences in this population compared to Western countries. In conclusion, imatib (copy) is effective and safe in treating patients with CML in chronic phase and proves to have a durable outcome. To our knowledge this is the first study reporting the response to imatib (copy) in an Algerian population. PMID- 29181140 TI - Foetal Haemoglobin and Disease Severity in Nigerian Children with Sickle Cell Anaemia. AB - Background: Foetal haemoglobin (HbF) is a major modifying factor influencing sickle cell disease (SCD) severity. Despite this, HbF estimation is not routinely done in Nigeria. The relationship between HbF and SCD severity among affected children is also poorly studied. Methods: In this descriptive cross-sectional study, we determined the relationship between steady state HbF levels and disease severity of Nigerian children aged 1 - 15 years with homozygous SCD. For each child, the socio-demographic characteristics and SCD clinical severity were determined. The latter was assessed based on the frequency of significant painful episodes, blood transfusion, and hospitalisation in the preceding 12 months; lifetime cumulative incidence of SCD-related complications; the degree of splenic and hepatic enlargement; current haematocrit and leucocyte count. Foetal haemoglobin levels were quantified with high-performance liquid chromatography. Results: The mean HbF level of the 105 children with SCA was 9.9 +/- 6.0%. Male had significantly lower mean HbF levels than females, 8.0 +/- 5.6% vs. 12.2 +/- 5.8% (p < 0.001). None of the children had severe disease. However, the 32 children with moderate disease had significantly lower mean foetal haemoglobin levels than the 73 with mild disease (7.7 +/- 5.6% vs 10.8 +/- 6.0% respectively). The mean HbF level was also significantly lower in children who had a history of acute chest syndrome and stroke compared to those without these complications, p = 0.002 and 0.010 respectively. Conclusion: Children with SCA who had a moderate disease and those with a history of life-threatening complications such as stroke and acute chest syndrome had significantly low HbF levels. Therefore, it is recommended that facilities for early quantification of foetal haemoglobin and HbF inducement were made available to reduce the morbidity and mortality among these children. PMID- 29181141 TI - Correlation to FVIII:C in Two Thrombin Generation Tests: TGA-CAT and INNOVANCE ETP. AB - Introduction: Several thrombin-generation tests are available, but few have been directly compared. Our primary aim was to investigate the correlation of two thrombin generation tests, thrombin generation assay-calibrated automated thrombogram (TGA-CAT) and INNOVANCE ETP, to factor VIII levels (FVIII:C) in a group of patients with hemophilia A. The secondary aim was to investigate inter laboratory variation for the TGA-CAT method. Methods: Blood samples were taken from 45 patients with mild, moderate and severe hemophilia A. The TGA-CAT method was performed at both centers while the INNOVANCE ETP was only performed at the Stockholm center. Correlation between parameters was evaluated using Spearman's rank correlation test. For determination of the TGA-CAT inter-laboratory variability, Bland-Altman plots were used. Results: The correlation for the INNOVANCE ETP and TGA-CAT methods with FVIII:C in persons with hemophilia (PWH) was r=0.701 and r=0.734 respectively.The correlation between the two methods was r=0.546.When dividing the study material into disease severity groups (mild, moderate and severe) based on FVIII levels, both methods fail to discriminate between them.The variability of the TGA-CAT results performed at the two centers was reduced after normalization; before normalization, 29% of values showed less than +/-10% difference while after normalization the number increased to 41%. Conclusions: Both methods correlate in an equal manner to FVIII:C in PWH but show a poor correlation with each other. The level of agreement for the TGA-CAT method was poor though slightly improved after normalization of data. Further improvement of standardization of these methods is warranted. PMID- 29181142 TI - Molecular Screening for Malaria among Blood Donors in a WHO Claimed Region of Egypt, Fayoum Governorate. AB - Background: Transfusion-transmitted malaria is undoubtedly a potential health hazard for blood recipients. Egypt is still on the prevention of reintroduction phase of malaria control program. Fayoum Governorate is considered one of the high-risk foci in Egypt due to its geology. However, no studies have been reported to evaluate the current status of subclinical Plasmodium infection based on sensitive molecular techniques. Moreover, screening of malaria is not listed within screening protocols of blood-borne pathogens in Fayoum blood banks. Objective: To assess the current prevalence of subclinical Plasmodium infection among blood donors of Fayoum inhabitants for transfusion biosafety. To predict any possibility of the reemergence of malaria in the governorate and the effectiveness of malaria control measures. Methods: A cross-sectional survey was conducted on 400 apparently healthy blood-donors in blood transfusion center of Fayoum University hospital from Jun 2012 to Jan 2013. Conventional PCR was used to detect the 18 S ssrRNA Plasmodium gene. Results: All Fayoum inhabitants' blood donors' samples were negative for Plasmodium infection. Conclusions: Current applied control, and preventive measures are valid in the context of blood transfusion biosafety in Fayoum blood banks and, therefore, the implementation of a routine malaria screening test in Fayoum blood banks is not merited at this time. PMID- 29181143 TI - Myeloid Neoplasms with Isolated Isochromosome 17q: a yet to be Defined Entity. AB - Myeloid neoplasms with isolated isochromosome 17q [MN i(17q)] has been described as a distinct entity with poor prognosis. However, literature reports show a considerable clinical and molecular heterogeneity. We describe a 58-year-old male patient who was diagnosed as refractory anemia with multilineage dysplasia and ringed sideroblasts with isolated i(17q). Though he initially responded well to erythropoietin, he gradually progressed to an aggressive form of MDS/MPN refractory to azacytidine and died 29 months after the first diagnosis. Notably, in contrast to disease advancement, his karyotype reverted to normal, whereas his mutational profile remained unchanged. To our knowledge, this is the first report of karyotype normalization during disease progression in patients with MN i(17q). It suggests that the i(17q) anomaly is dispensable for the leukemic transformation and highlighting the underlying clinical and molecular complexity which both has to be resolved before the establishment of MN with isolated i(17q) as a distinct entity. PMID- 29181145 TI - The Impact of Diagnostic Code Misclassification on Optimizing the Experimental Design of Genetic Association Studies. AB - Diagnostic codes within electronic health record systems can vary widely in accuracy. It has been noted that the number of instances of a particular diagnostic code monotonically increases with the accuracy of disease phenotype classification. As a growing number of health system databases become linked with genomic data, it is critically important to understand the effect of this misclassification on the power of genetic association studies. Here, I investigate the impact of this diagnostic code misclassification on the power of genetic association studies with the aim to better inform experimental designs using health informatics data. The trade-off between (i) reduced misclassification rates from utilizing additional instances of a diagnostic code per individual and (ii) the resulting smaller sample size is explored, and general rules are presented to improve experimental designs. PMID- 29181144 TI - Evaluation of Electrospun Nanofiber-Anchored Silicone for the Degenerative Intervertebral Disc. AB - The nucleus pulposus (NP) substitution by polymeric gel is one of the promising techniques for the repair of the degenerative intervertebral disc (IVD). Silicone gel is one of the potential candidates for a NP replacement material. Electrospun fiber anchorage to silicone disc, referred as ENAS disc, may not only improve the biomechanical performances of the gel but it can also improve restoration capability of the gel, which is unknown. This study successfully produced a novel process to anchor any size and shape of NP gel with electrospun fiber mesh. Viscoelastic properties of silicone and ENAS disc were measured using standard experimental techniques and compared with the native tissue properties. Ex vivo mechanical tests were conducted on ENAS disc-implanted rabbit tails to the compare the mechanical stability between intact and ENAS implanted spines. This study found that viscoelastic properties of ENAS disc are higher than silicone disc and comparable to the viscoelastic properties of human NP. The ex vivo studies found that the ENAS disc restore the mechanical functionality of rabbit tail spine, after discectomy of native NP and replacing the NP by ENAS disc. Therefore, the PCL ENF mesh anchoring technique to a NP implant can have clinical potential. PMID- 29181146 TI - Metastatic prostate adenocarcinoma to intradural foramen magnum. AB - Intradural metastatic tumors are rarely reported in foramen magnum (FM), including cases of melanoma, pituitary carcinoma, thyroid carcinoma, and prostate carcinoma metastases. We report a 68-year-old male who presented with right-sided headache, progressive swallowing difficulty requiring gastrostomy tube and hoarseness over the course of 1 year. Images revealed a heterogeneous, contrast enhancing lesion in the FM that compressed the anterior aspect of the medulla and upper spinal cord. Although metastatic tumor was considered in differential diagnosis, presumptive diagnosis was FM meningioma due to lack of bone destruction or sclerosis on CT and T2W isointense and T1W hypointense appearance on MRI. The patient underwent gross total resection via right far-lateral transcondylar approach. Histopathological examination revealed prostate carcinoma metastasis. To the best of our knowledge this is the second case report of an intradural prostate carcinoma metastasis in the FM. PMID- 29181147 TI - A unique case of popliteal artery transection after a motorcycle collision. AB - Popliteal artery injuries may have devastating consequences if not recognized in a timely fashion. The risk of delayed diagnosis of a vascular injury is particularly high in blunt trauma to the lower extremity. We present a case of popliteal artery injury that is unusual in two respects: severity (a complete transection in the setting of a blunt injury) and lack of clinical and radiographic signs of the commonly associated musculoskeletal injuries. PMID- 29181148 TI - Abdominal compartment syndrome due to spontaneous rectus sheath hematoma with extension into the retroperitoneal space. AB - Rectus sheath hematoma (RSH) is an increasingly common clinical condition in our hospitals due to the increasing use of anticoagulant therapies for various purposes among our patients. Treatment of spontaneous RSH is generally conservative. For continued bleeding, interventional radiologic identification and subsequent embolization is an effective option. Surgery usually involves significant morbidity and is considered a technique of last resort. In this case report, we describe the case of middle aged female who developed abdominal compartment syndrome (ACS) from a large RSH that had extended into the retroperitoneum. The patient underwent abdominal decompression with removal of the hematoma and subsequently fared very well. Patients with large RSHs extending into the retroperitoneum should undergo constant monitoring of their abdominal pressures for early detection and treatment of potentially deadly condition of ACS. PMID- 29181150 TI - Colo-ovarian fistula. AB - Colo-ovarian fistula is a rare entity. The case of a 54-year-old female with a colo-ovarian fistula is presented. We describe our experience in managing this complication of diverticulitis and propose a workup and treatment plan. Initial imaging and diagnostic studies are described. En-bloc resection of the sigmoid colon and ovary was performed. A review of the literature is presented. PMID- 29181149 TI - A case of pneumatosis intestinalis during neoadjuvant chemotherapy with cisplatin and 5-fluorouracil for esophageal cancer?. AB - Pneumatosis intestinalis (PI) is a relatively rare disease. A 70-year-old man with stage II squamous cell carcinoma of the middle thoracic esophagus was administered cisplatin plus 5-fluorouracil (CF) therapy as neoadjuvant chemotherapy. On Day 14 of the first course of CF therapy, he complained of acute abdominal pain. Computed tomography (CT) revealed PI of the entire colon and a small air bubble in the mesentery. A colonoscopy revealed that there was no finding suggestive of ischemia. Because there was no sign of peritoneal irritation, conservative treatment was selected. On Day 7 after PI diagnosis, CT indicated the disappearance of PI. The patient underwent a radical esophagectomy. Intraoperative laparoscopic findings showed the serosa of the colon to be intact. The patient was discharged without any complications. It is important to take into account that CF therapy may cause PI and that PI can be treated conservatively. PMID- 29181151 TI - Socio-demographic determinants of the severity of locomotor disability among adults in Bangladesh: a cross-sectional study, December 2010-February 2011. AB - Background: Socio-demographic variables are widely known to have an association with the presence of any disability. However, the association between the severity of locomotor disability and socio-demographic variables has never been investigated in Bangladesh. Methods: A cross sectional survey of adults with locomotor disabilities was conducted between December 2010 and February 2011 at the Centre for the Rehabilitation of the Paralysed (CRP), Dhaka, Bangladesh. During the study period 328 adults with locomotor disabilities met our selection criteria, but 316 consented and participated in the study. The 55-item Locomotor Disability Scale was used to measure disability. This study investigated the socio-demographic determinants of the severity of locomotor disability: age, gender, marital status, educational attainment, occupation, income status, type of house, living in own/rented house, household monthly income, household population and area of residence. Results: Participants' age was positively associated with the severity of their locomotor disability (beta = 0.01; 95% CI: 0.004 to 0.02), adjusting for diagnosis and other socio-demographic variables studied. Individuals who had an income experienced 0.35 (95% CI: -0.63 to -0.07) points decrease in the severity of disability than those did not have an income, adjusting for diagnosis and rest of the socio-demographic variables studied. In comparison to the unemployed individuals, students, homemakers, and individuals in elementary occupation respectively experienced 0.75 (95% CI: -1.08 to -0.43), 0.51 (95% CI: -0.82 to -0.19) and 0.37 (95% CI: -0.66 to -0.08) points decrease in the severity of locomotor disability, adjusting for diagnosis and rest of the socio-demographic variables studied. Conclusions: The severity of locomotor disability has an association with individuals' age, income status and occupation of the adults with such disability in Bangladesh. No such association was evident with other socioeconomic position and demographic variables. This finding suggests that people with locomotor disabilities in Bangladesh experience similar disabling built and attitudinal environments irrespective of their socioeconomic positions and demographic characteristics. Further community-based studies are needed to confirm such conclusions. PMID- 29181152 TI - Impact of assay temperature on antibody binding characteristics in living cells: A case study. AB - Kinetic and thermodynamic studies of ligand-receptor interactions are essential for increasing the understanding of receptor activation mechanisms and drug behavior. The characterization of molecular interactions on living cells in real time goes beyond most current binding assays, and provides valuable information about the dynamics and underlying mechanism of the molecules in a living system. The effect of temperature on interactions in cell-based assays is, however, rarely discussed. In the present study, the effect of temperature on binding of monoclonal antibodies, cetuximab and pertuzumab to specific receptors on living cancer cells was evaluated, and the affinity and kinetics of the interactions were estimated at selected key temperatures. Changes in the behavior of the interactions, particularly in the on- and off-rates were observed, leading to greatly extended time to reach the equilibrium at 21 degrees C compared with at 37 degrees C. However, the observed changes in kinetic characteristics were less than a factor of 10. It was concluded that it is possible to conduct real-time measurements with living cells at different temperatures, and demonstrated that influences of the ambient temperature on the interaction behavior are likely to be less than one order of magnitude. PMID- 29181153 TI - Efficacy of alogliptin combined with motor imagery under hyperbaric oxygen in diabetic nephropathy with silent cerebral infarction. AB - In the present study, we evaluated the curative effect of dipeptidyl peptidase-IV (DPP-IV) inhibitor alogliptin combined with motor imagery under hyperbaric oxygen in diabetic nephropathy (DN) with silent cerebral infarction (SCI). Two-hundred newly diagnosed DN patients with and without SCI were included. The SCI patients were divided into two treatment groups: Alogliptin (A group, n=50) and alogliptin combined with motor imagery under hyperbaric oxygen (B group, n=50). The degrees of neurocognitive dysfunction were evaluated at baseline and after 6 months of treatment. Thromboelastograms (TEGs) mapping were conducted. Serum glycoprotein VI (GPVI) mRNA expression and urine 11-DH-TXB2 levels were determined. Compared to group A patients, the severity of neurofunctional defects, GPVI mRNA expression and 11-DH-TXB2 levels were significantly lower in group B (P<0.05), while comprehensive, MoCA scores were higher in group B. The MoCA subscores of visuospatial/executive function, attention and concentration were significantly higher compared to group A (P<0.05). The sub-scores of computation, abstract thinking, language competence, memory and orientation were also higher in group B but the differences were not significant (P>0.05). TEG indexes were improved in both groups after treatment as manifested by increased R and K values, but there was significant improvement in group B. Intra-group comparisons revealed a time dependent effect of treatment. In conclusion, the treatment of alogliptin combined with motor imagery under hyperbaric oxygen can better promote thrombolysis absorption, restore brain damage and improve neurocognitive function in DN with silent cerebral infarction.

Less. is a perennial plant known for its versatile uses in traditional medicine. Previous findings have shown that the extracts of Pluchea indica possess significant anti-inflammatory, anti-ulcer and anti-tuberculosis activity. The aim of this study was to demonstrate the anticancer activity of the hexane fraction of P. indica root extract (H-PIRE) in human glioblastoma cells using flow cytometric and western blot analysis. The results shoewd that, H-PIRE suppressed the growth of glioblastoma cells in a dose-dependent manner. H-PIRE treatment markedly decreased the population of cells in S and G2/M phases. The significant upregulation of acidic vesicular organelle (AVO) was detected during H-PIRE treatment. The expression levels of microtubule-associated light chain 3 II (LC3-II) protein, phosphorylated JNK and phosphorylated p38 were significantly increased, confirming the occurrence of autophagy during the process. Finally, the combination treatment of H-PIRE and LY294002, a pan PI3K inhibitor, further decreased cell viability, suggesting an additive anticancer effect. Taken together, our results suggest that H-PIRE suppresses the proliferation of glioblastoma cells by inducing cell cycle arrest and autophagy. PMID- 29181155 TI - Comparison of the effect of the aerobic glycolysis inhibitor dichloroacetate and of the Krebs cycle inhibitor LW6 on cellular and humoral alloimmunity. AB - Cell metabolism is altered during T-cell and B-cell activation and differentiation. Clarifying the exact metabolic shifts may lead to the development of new immunosuppressive medications. In this study, the effect of the aerobic glycolysis inhibitor dichloroacetate (DCA) and of the Krebs cycle enzyme malate dehydrogenase 2 (MDH2) inhibitor LW6 on T-cell alloimmune clonal expansion and on alloantibody production, was evaluated. T-cell clonal expansion was assessed in two-way mixed lymphocyte reaction (MLR). Humoral alloimmunity was evaluated by the alloantibody production in one-way MLR. For this purpose, an antibody-mediated complement-dependent cytotoxicity assay was developed in which the supernatants from one-way MLRs were used against resting peripheral blood mononuclear cells (PBMCs) derived from the same individual that contributed the stimulator cells for the respective MLR. DCA had a minimum effect on alloimmune T cell clonal expansion, whereas it increased humoral immunity significantly. LW6 decreased both alloimmune T-cell proliferation and alloantibody production. The results indicate that MDH2 may be a perfect target for the development of new immunosuppressive medications, especially when inhibition of both cellular and humoral alloimmunity is desirable. PMID- 29181156 TI - Proteomic profile of the lens in a streptozotocin-induced diabetic rat model using shotgun proteomics. AB - Streptozotocin (STZ)-induced diabetic rats (STZ rats) were used to investigate diabetic cataracts. In the current study, a shotgun liquid chromatography (LC)/mass spectrometry (MS)-based global proteomic analysis method was used to examine the mechanism of lens opacification as a result of hyperglycemia in STZ rats. The 6-week old Wistar rats were injected with STZ for 2 days (100 mg/kg/day, i.p.) and housed for 3 weeks. The plasma glucose levels were identified to be significantly higher when compared with the normal rats and insulin was not detected in the STZ rats. Furthermore, opacification of the cortical epithelium was observed in the lenses of STZ rats. A total of 235 proteins were identified in the lenses of the STZ rats and 229 in the lenses of the normal rats. A label-free semi-quantitative method, based on spectral counting, identified 52 proteins that were differentially expressed in the lenses of STZ rats compared with normal rats. In particular, superoxide dismutase, which is a critical antioxidant enzyme that detoxifies superoxide through redox cycling, was downregulated when analyzed by the semi-quantitative method. In addition, phosphorylated-p38, which is important in the signaling pathway involved in the oxidative stress response, was significantly increased in the lenses of STZ rats when compared with normal rats (P<0.05). Thus, the changes in protein expression were evaluated in the lenses of STZ rats using a shotgun LC/MS based global proteomic analysis approach, and a decrease in antioxidant enzymes and an increase in oxidative stress were identified in the lenses of STZ rats. Further studies are required to examine the role of these proteins in the onset or progression of diabetic cataracts. PMID- 29181157 TI - Non-syndromic isolated dominant optic atrophy caused by the p.R468C mutation in the AFG3 like matrix AAA peptidase subunit 2 gene. AB - Autosomal dominant optic atrophy (DOA) is the most frequent form of hereditary optic atrophy, a disease presenting with considerable inter- and intra-familial clinical variability. Although a number of mutations in different genes are now known to cause DOA, many cases remain undiagnosed. In an attempt to identify the underlying genetic defect, whole exome sequencing was performed in a 19-year-old male that had been affected by isolated DOA since childhood. The exome sequencing revealed a pathogenic mutation (p.R468C, c.1402C>T) in the AFG3 like matrix AAA peptidase subunit 2 (AFG3L2) gene, a gene known to be associated with spinocerebellar ataxia. The patient did not show any signs other than DOA. Thus, the result demonstrates the possibility that mutations in the AFG3L2 gene may be a cause of isolated autosomal DOA. PMID- 29181158 TI - Serum pepsinogen and gastrin-17 as potential biomarkers for pre-malignant lesions in the gastric corpus. AB - There is a lack of non-invasive screening modalities to diagnose chronic atrophic gastritis (CAG) and intestinal metaplasia (IM). Thus, the aim of the present study was to determine the sensitivity and specificity of serum pepsinogen I (PGI), PGI:II, the PGI:II ratio and gastrin-17 (G-17) in diagnosing CAG and IM, and the correlations between these serum biomarkers and pre-malignant gastric lesions. A cross-sectional study of 72 patients (82% of the calculated sample size) who underwent oesophageal-gastro-duodenoscopy for dyspepsia was performed in the present study. The mean age of the participants was 56.2+/-16.2 years. Serum PGI:I, PGI:II, G-17 and Helicobacter pylori antibody levels were measured by enzyme-linked immunosorbent assay. Median levels of PGI:I, PGI:II, the PGI:II ratio and G-17 for were 129.9 ug/l, 10.3 ug/l, 14.7 and 4.4 pmol/l, respectively. Subjects with corpus CAG/IM exhibited a significantly lower PGI:II ratio (7.2) compared with the control group (15.7; P<0.001). Histological CAG and IM correlated well with the serum PGI:II ratio (r=-0.417; P<0.001). The cut-off value of the PGI:II ratio of <=10.0 demonstrated high sensitivity (83.3%), specificity (77.9%) and area under the receiver operating characteristic curve of 0.902 in detecting the two conditions. However, the sensitivity was particularly low at a ratio of <=3.0. The serum PGI:II ratio is a sensitive and specific marker to diagnose corpus CAG/IM, but at a high cut-off value. This ratio may potentially be used as an outpatient, non-invasive biomarker for detecting corpus CAG/IM. PMID- 29181159 TI - Investigation of the association between the MDM2 T309G polymorphism and gastric cancer. AB - Murine double minute clone 2 oncoprotein (MDM2) is a key component in the regulation of the tumour suppressor p53. The association between the MDM2 polymorphism and gastric cancer (GC) has been investigated in Turkish population. In the present case-control study, the aim was to investigate the association between genetic polymorphisms of the MDM2 gene (a major regulator of p53 function) and primary GC risk in a Turkish population. The polymorphism, T309G (rs2279744) in the MDM2 gene was determined in patients with GC (n=65) and in healthy control subjects (n=67) using the polymerase chain reaction-restriction fragment length polymorphism method. The findings were evaluated using logistic regression and chi2 tests. No statistically significant differences were observed between the control subjects and patients with GC regarding smoking status. A comparison between GC cases and control subjects indicated a statistically significant difference for family history of cancer [odds ratio (OR)=0.17; 95% confidence interval (CI), 0.05-0.56; chi2=0.19; P=0.01]. A significant difference was identified in the GG genotype distribution between GC patients and control subjects (OR=4.58; 95% CI, 1.18-17.79; P=0.022). Thus, the results of the present study indicate that the MDM2 gene T309G intron (GG) genotype may be an important risk factor for GC development in the Turkish population. PMID- 29181160 TI - Secondary central nervous system lymphoma surrounding a region injured by subarachnoid hemorrhage and subsequent aneurysmal clipping. AB - The present case study describes a rare case of secondary central nervous system (CNS) lymphoma that infiltrated the dura and leptomeninges around the area injured by subarachnoid hemorrhage and subsequent aneurysmal clipping. Invasion of the CNS was observed by computed tomography as slurred fissures of the right parietal lobe adjacent to the surgery area. Subdural and subarachnoid enhancement overlapping the area injured by past surgical procedures was observed by contrast enhanced magnetic resonance imaging. Surgical resection revealed B-cell lymphoma infiltrating the dura and leptomeninges surrounding the post-hemorrhagic area. The patient was subsequently diagnosed with systemic lymphoma and bone marrow invasion, and multiple lymph node swelling. To the best of our knowledge, this is the first report of malignant lymphoma involving the CNS overlapping a previously injured area. PMID- 29181161 TI - Effects of hydration combined with Shenfu injection on contrast-induced acute kidney injury in acute coronary syndrome patients undergoing percutaneous coronary intervention. AB - The aim of the present study was to evaluate the efficacy and safety of the Shenfu injection (SFI) in the prevention of contrast-induced acute kidney injury (CI-AKI) in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). A single-center prospective and randomized controlled trial was performed and 148 ACS patients undergoing PCI were divided randomly into control (n=74; receiving only 0.9% sodium chloride solution for routine hydration) and intervention (n=74; based upon routine hydration and receiving SFI) groups. Serum creatinine (Scr), blood urea nitrogen and urinary neutrophil gelatinase-associated lipocalin (NGAL) were evaluated at the start, and 1 and 2 days after PCI. Among the 148 patients, 14 (9.4%) experienced CI-AKI subsequent to the procedure. CI-AKI occurred in 2.7% of the SFI group and 16.2% of the control group (P<0.05). The incidence of CI-AKI was lower in the intervention group when compared with the control. No serious adverse effects were observed in all patients. No differences between the levels of Scr and estimated glomerular filtration rate in the two groups were identified. However, 12 h after PCI, the urinary NGAL level in the control group was significantly higher than that in the SFI group (P<0.05). Thus, hydration combined with SFI was identified to be more effective than hydration with sodium chloride in the prevention of CI-AKI in ACS patients undergoing PCI. PMID- 29181162 TI - Assessing predictors for the success of GnRH antagonist protocol in reproductive women in IVF/ICSI - in fresh cycles. AB - The aim of the present study was to evaluate the factors that affect the success rate of gonadotropin-releasing hormone antagonist on in vitro fertilization/intracytoplasmic sperm injection cycles. Multivariate analysis was performed to assess the factors that influence the outcomes, such as oocytes retrieved, and the success of pregnancy. The results showed that E2, P on human chorionic gonadotropin (HCG) day and body mass index (BMI) were positively correlated with the number of oocytes retrieved (P=0.001, P=0.024, P=0.017, respectively). The duration of infertility as well as the luteinizing hormone on HCG day were negatively correlated with the number of oocytes (P=0.048, P=0.002, respectively). The age of the women and P on HCG day were negatively correlated with successful pregnancy (P<0.001, P=0.022). In conclusion, some parameters, such as E2, P, and LH on the HCG day, as well as age and BMI, may affect treatment outcomes. PMID- 29181163 TI - Oxidative stress and prostatic diseases. AB - Prostatic diseases are a common health problem among males in Western countries, and include chronic prostatic diseases, which have an unclear pathogenesis and few treatment options. In vitro and in vivo studies describe oxidative stress as a major pathway involved in the occurrence of benign prostatic hyperplasia, prostatic cancer and chronic prostatitis. Thus, the oxidative stress cascade is a potential target for the treatment of prostatic diseases. This paper presents a systematic review of the available data concerning the association between oxidative stress and the most common chronic prostatic diseases, and describes the available treatment options that act upon this pathway. PMID- 29181164 TI - Recent findings on epigenetic gene abnormalities involved in uterine cancer. AB - Selective aberrant genetic effects that do not depend on abnormal DNA sequences are referred to as epigenetic abnormalities and are involved in carcinogenesis. In uterine cancer, various genes involved in apoptosis, cell cycle, DNA repair, cell proliferation and cell adhesion are abnormally methylated, resulting in gene silencing. Reversal of such epigenetic abnormalities in cancer cells is a potential strategy for cancer therapy, and studies on epigenetic abnormalities and treatment methods in uterine cancer are in progress. These include the evaluation of 5-hydroxymethylcytosine, which is present in cancer tissues at lower levels compared with those in normal tissues, as a prognostic marker in cervical cancer; combination therapy with 5-azacytidine and cisplatin; combination treatment focusing on tumor necrosis factor-related apoptosis inducing ligand in cervical cancer; studies focusing on DNA mismatch repair in endometrial cancer; and use of a demethylating agent to reactivate tumor suppressor genes and inhibit tumor proliferation. Detection of epigenetic changes using biomarkers may be used for histological classification, evaluation of disease progression and identification of compounds that are able to modulate epigenetic changes and may be useful for uterine cancer treatment. PMID- 29181165 TI - Primary extraosseous plasmacytoma of the parotid gland: A case report and literature review. AB - Extraosseous plasmacytoma (EOP) is an uncommon malignant tumour that is characterised by the monoclonal proliferation of abnormal plasma cells in soft tissue; however, EOP lacks the defining features of multiple myeloma or medullary plasmacytoma. Although the majority of EOP lesions occur in the head and neck, EOP of the parotid gland is extremely uncommon. The present study aimed to explore the clinical features of parotid plasmacytoma, in addition to the diagnostic and therapeutic options for its management. Using the Medline database, a search was conducted for articles published on the topic of 'parotid plasmacytoma' up until the year 2016. A total of 20 cases were evaluated, including 19 clinical cases from the literature and 1 new clinical case from our hospital. Among the 19 previously published cases, the mean age at the time of diagnosis of EOP was 65.1+/-10.9 years (range, 38-78 years). Plasmacytomas were located unilaterally in all cases: On the right side in 9 patients (47.4%), on the left side in 10 patients (52.6%). Treatment included chemotherapy in 3 cases, radiotherapy in 11 cases and surgical removal in 15 cases. The diagnosis of EOP is based on the presence of a localised tumour comprising monoclonal plasma cells, and EOP is identical to multiple myeloma in this regard; however, EOP, in contrast to multiple myeloma, does not exhibit the signs that are indicative of disseminated disease, such as additional lesions on skeletal radiological examination, plasmacytosis in the bone marrow, and hypercalcaemia, anaemia, or renal failure. Thus, EOP must be considered in the differential diagnosis of parotid gland lesions in order to avoid confusion with other tumoural diseases. PMID- 29181166 TI - Successful and long-term response to trastuzumab plus paclitaxel combination therapy in human epidermal growth factor receptor 2-positive extramammary Paget's disease: A case report and review of the literature. AB - A 58-year-old woman with a histologically confirmed diagnosis of vulvar extramammary Paget's disease (EMPD) was referred to our hospital due to locally advanced and relapsed EMPD. The patient had undergone surgical resection three times for relapsed vulvar EMPD over a period of 12 years, but developed locally advanced and unresectable EMPD. As pathological examination indicated that the lesion was positive for human epidermal growth factor receptor 2 (HER2) on immunohistochemical staining, the patient was treated with trastuzumab plus paclitaxel. The primary tumor mass and lymph node metastasis regressed successfully with combined trastuzumab and paclitaxel therapy, and the disease has been stable for >2 years after the initiation of treatment. These observations suggest that HER2 status must be determined in patients with advanced and/or metastatic extramammary Paget's disease and therapy with HER2 inhibitors should be considered as an option for the treatment of HER2-positive EMPD. PMID- 29181167 TI - Long-term outcomes of laparoscopy vs. open surgery for colorectal cancer in elderly patients: A meta-analysis. AB - The long-term outcome of laparoscopic surgery for geriatric patients with colorectal cancer remains unclear due to decreased functional reserves and increased medical comorbidities. A meta-analysis was performed in the present study to compare the long-term outcome between laparoscopy and laparotomy. Randomized controlled trials and comparative studies regarding laparoscopy vs. open surgery for colorectal cancer in elderly patients were searched in Pubmed, Embase, and Cochrane library between inception and April 20, 2017. The methodological quality of the cohort studies was evaluated using the Newcastle Ottawa Scale. The meta-analysis was performed using Stata v12.0 software. Eight cohort studies were enrolled in the meta-analysis. Laparoscopic surgery was associated with a higher 3-year survival rate compared with open surgery [risk ratio (RR), 0.74; 95% confidence interval (CI), 0.61-0.90; P=0.003]. No significant difference was identified between laparoscopy and laparotomy regarding the 5-year survival rate (RR, 0.93; 95% CI, 0.78-1.11, P=0.424). The results of the meta-analysis indicated that the use of laparoscopic surgery on geriatric patients with colorectal cancer should be increased due to more improved long-term outcomes. All the studies included in the meta-analysis were case-control studies with selection bias and other confounding factors. Thus, larger sample sizes and multicenter randomized controlled trials are required to further validate the use of laparoscopic surgery as the preferred therapeutic option for elderly patients with colorectal cancer. PMID- 29181168 TI - Schwannoma of the vagina - a common tumor but a rare location: A case report. AB - Schwannomas are nerve sheath tumors arising from Schwann cells. These tumors usually present as benign, relatively slow-growing, solitary, encapsulated, painless masses. Schwannomas rarely occur in the vagina, and have not been fully recognized as gynecological tumors. We herein describe the case of a patient who presented with a schwannoma occurring in the wall of vagina, with non-specific symptoms lasting for ~1 year. The vaginal mass was incidentally detected during a sonographic examination and the patient was referred for surgical resection. The surgery was uncomplicated and the vaginal tumor was diagnosed as benign schwannoma. The immunohistochemical examination revealed positivity for vimentin, S-100 and glial fibrillary acidic protein, whereas discovered on GIST-1, CD117, CD34, desmin, smooth muscle actin and cytokeratin were negative. Tumors occurring in the vagina are common and are of variable histological types, with a wide range of pathological characteristics and complications. Schwannoma should be considered in the differential diagnosis in patients presenting with atypical symptoms from the gynecological tract. Immunohistochemical staining is required for confirmation of the diagnosis of schwannoma, and for distinguishing this entity from other homologous tumors. PMID- 29181169 TI - Retrospective analysis of single-agent nab-paclitaxel in patients with platinum resistant non-small cell lung cancer. AB - A retrospective study was conducted to investigate the efficacy and toxicity of single-agent nab-paclitaxel in 67 patients with platinum-resistant non-small cell lung cancer in Kansai Medical University Hospital from August 2013 to December 2015. Overall, 25% of patients experienced disease progression, 48% exhibited a partial response, 27% had stable disease and 0% had a complete response. The median progression-free survival (PFS) time was 4.8 months and the median overall survival time was 18.2 months. There was no statistically significant difference in PFS between patients with non-squamous carcinoma and squamous carcinoma, or between second-line use and post-second-line use. The most common severe adverse event was neutropenia, followed by interstitial lung disease, infection and fatigue. The results revealed that single agent nab-paclitaxel was associated with an acceptable level of toxicity and a favorable response. This regimen has been developed recently, thus it has not been sufficiently evaluated its toxicity and efficacy. Additional studies to evaluate these parameters in non-small cell lung cancer are warranted. PMID- 29181170 TI - Role of Kruppel-like factor 4 and heat shock protein 27 in cancer of the larynx. AB - Late detection and lack of standard treatment strategies in larynx cancer patients result in high levels of mortality and poor prognosis. Prognostic stratification of larynx cancer patients based on molecular prognostic tumor biomarkers may lead to more efficient clinical management. Kruppel-like factor 4 (KLF4) and Heat Shock Protein 27 (HSP27) have an important role in tumorigenesis and are considered promising candidate biomarkers for various types of cancer. However, their role in larynx carcinoma remains to be elucidated. The present study aimed to determine KLF4 and HSP27 expression profiles in laryngeal tumors. The protein and mRNA expression levels of KLF4 and HSP27 were evaluated by immunohistochemical and reverse transcription-polymerase chain reaction analyses in 44 larynx carcinoma samples and 21 normal tissue samples, and then correlated with clinical characteristics. A differential expression of KLF4 and HSP27 was observed between normal and tumor tissues. The protein and mRNA expression levels of KLF4 were significantly decreased in larynx squamous cell carcinoma (LSCC) compared with normal tissue, whereas HSP27 was significantly overexpressed in tumor tissues compared with normal tissues, at the protein and mRNA levels. KLF4 expression decreased gradually with tumor progression whereas HSP27 expression increased. A significant difference was observed between stages I and IV. KLF4 and HSP27 exhibit opposite functions and roles in the carcinogenic process of LSCC. Their role in laryngeal cancer initiation and progression emphasizes their use as potential future targets for prognosis and treatment. KLF4 and HSP27 expression levels may act as potential biomarkers in patients with cancer of the larynx. PMID- 29181171 TI - Subserous invasion of VEGF-C-producing cancer cells is a possible risk factor for ileal ulceration in the non-metastatic mucosal layer during bevacizumab-combined chemotherapy for recurrent ovarian cancer: A case report. AB - A 65-year-old woman received chemotherapy using taxane and carboplatin prior and following optimal debulking surgery for ovarian cancer stage IV. Five months later, intra-abdominal recurrence was diagnosed, and second-line chemotherapy using nogitecan and bevacizumab was administered. After five courses, the patient presented with a symptom of subileus and subsequent intestinal perforation occurred. An emergent surgery revealed two perforation sites and longitudinally extended ulcerative lesions in the ileum. Pathologically, although metastatic sites were not observed in the submucus layer just beneath the ulcers, there were a number of vascular endothelial growth factor (VEGF)-C-positive cancer cell invasion sites along with marked edema and an increase of the lymphatic endothelial cell marker 'podoplanin'-positive cells in subserous regions. Since bevacizumab is able to inhibit VEGF-A, but not VEGF-C, and induce compensatory increase in VEGF-C production, these findings suggest that the local disturbance of lymphatic circulation in the subserous regions by VEGF-C-producing cancer cells is a possible risk factor for the development of intestinal ulceration and perforation during bevacizumab therapy. PMID- 29181172 TI - Trigeminal neurofibroma in the infratemporal fossa arising from the inferior alveolar nerve: A case report. AB - Solitary neurofibromas arising from cranial nerves are rare, and those arising from the peripheral divisions of the trigeminal nerve are even rarer. Although infratemporal fossa (ITF) masses are challenging to remove, certain approaches are considered feasible for this region. The present study reports a rare case of an ITF neurofibroma arising from the inferior alveolar nerve. The 27-year-old male patient presented with numbness of the right jaw. A radiological examination revealed a large mass occupying the ITF, from the mandible to the foramen ovale, originating from the inferior alveolar nerve in the mandible. The tumor was successfully excised via a transtemporal approach followed by a transoral retromolar approach. A histological examination confirmed the diagnosis of neurofibroma. The present case demonstrates that a combination of the transtemporal and transoral-retromolar approaches may provide wide access to the ITF region. PMID- 29181173 TI - Transverse colon schwannoma treated by endoscopic mucosal resection: A case report. AB - Gastrointestinal (GI) schwannoma is one of the rarest tumors of the GI tract. We herein describe the case of a 70-year-old female patient who presented for surveillance colonoscopy. The examination detected a 1-cm polyp that was removed by snare cautery polypectomy. Immune and histochemical staining revealed spindle cells that were positive for S-100 and vimentin, but negative for CD34 and smooth muscle actin, consistent with GI schwannoma. This case is noteworthy as GI schwannomas usually present in the stomach, making the finding of a colonic schwannoma of clinical interest. Furthermore, the present case was treated by removing the tumor endoscopically, in contrast to more invasive methods. PMID- 29181174 TI - Rapid occurrence of left ventricular thrombus associated with platinum-based chemotherapy plus cetuximab for the treatment of metastatic squamous cell carcinoma of the head and neck: A case report. AB - Platinum-based chemotherapy plus cetuximab represents the first-line treatment for recurrent or metastatic squamous cell carcinoma of the head and neck. The most common adverse events associated with cetuximab are infusion reactions and skin reactions, and a risk of venous thromboembolic events has also recently been reported in association with cetuximab. It is well known that thrombosis is a common complication of malignancy, and represents the second most frequent cause of mortality in cancer patients. The present study reports the case of a 79-year old man who presented with lung and liver metastases from tongue squamous cell carcinoma, for which platinum-based chemotherapy plus cetuximab was administered. After 1 cycle, the patient showed rapid growth of a left ventricular (LV) thrombus, despite ongoing antiplatelet therapy for an old myocardial infarction. Anticoagulant therapy was administered to treat the LV thrombus, which resolved within 1 week. To the best of our knowledge, this represents the first reported case of rapidly occurring LV thrombus associated with platinum-based chemotherapy plus cetuximab. Platinum-based chemotherapy plus cetuximab may be associated with a higher risk of embolic thrombus. PMID- 29181175 TI - Peripheral blood neutrophil count as a prognostic factor for patients with hepatocellular carcinoma treated with sorafenib. AB - Sorafenib is currently the only efficient molecular targeted therapy for hepatocellular carcinoma (HCC), although its effect is relatively moderate and variable between individuals. The present study aimed to evaluate the significance of peripheral blood neutrophils in the prognosis of HCC patients treated with sorafenib. A total of 464 patients with HCC were treated with sorafenib at Zhongshan Hospital (Shanghai, China) between January 1st, 2008 and December 31st, 2012, among which 120 patients were enrolled in the study. The optimal cutoff point for low vs. high neutrophil count (3.65*109) was obtained from a receiver operating characteristic curve. Overall survival (OS) was compared between the patients with low and high peripheral neutrophil counts. Univariate and multivariate analyses were used to explore the prognostic factors associated with OS in the patients treated with sorafenib. A nomogram model was also performed to predict the OS times of these patients. The median OS time was 9.0 months (95% confidence interval, 5.9-12.1 months) in the whole group of patients, with 1-, 2- and 3-year OS rates of 36, 24 and 16%, respectively. Using a cutoff level of 3.65*109 neutrophils/l, the median OS time was longer in the group of patients with a low peripheral neutrophil count than in those with a high peripheral neutrophil count (11.5 vs. 5.0 months, respectively; P<0.001). The multivariate analysis showed that peripheral neutrophil count, alpha fetoprotein level and tumor size were independent prognostic factors for OS. In addition, using the nomogram model for the prediction of OS, the Harrell's c index was 0.79. Therefore, it was concluded that a lower peripheral blood neutrophil count was associated with a better prognosis following treatment with sorafenib therapy. PMID- 29181176 TI - Chemoprevention using folic acid for dysplastic lesions of the larynx. AB - Folate deficiency may be directly associated with carcinogenesis. Folate supplementation may reduce the risk of progression in a mucosa that is already genetically altered. The aim of the present study was to determine the role of folic acid in the treatment of mild and moderate laryngeal dysplasia recurring after surgery. The data obtained by laryngoscopy, measurement of serum folate levels and functional vocal assessment with the GIRBAS scale and VHI questionnaire were compared in patients who had received folic acid with a homogeneous group of patients with dysplasia who had not undergone any therapy. A total of 24 patients suffering from recurrence of mild or moderate laryngeal dysplasia (n=12, group A) were treated with 400 mg folic acid per os, once daily for 6 months. The patients in group B (n=12) received no treatment and were used as the control group. In group A, 7 (58%) patients exhibited a complete response, with clinically evident regression of leukoplakia, 3 (25%) displayed a partial decrease in the lesions with reduced volume of the area involved, whereas 2 patients exhibited no change. As regards patients in control group B, 8 (67%) exhibited no change, in 1 case there was a spontaneous regression, and in 3 (25%) there was disease progression with suspected malignant transformation, leading to repeat surgery. Therefore, folate deficiency may be considered to be a factor predisposing to precancerous lesions, and dietary folate supplementation may prevent and reduce the emergence of cancer. PMID- 29181177 TI - Recurrent maxillary sinus cancer with only adrenal metastasis. AB - Maxillary sinus cancer is rare, and often presents as a locally advanced disease. Recurrence commonly occurs locoregionally, while fewer patients present with distant metastasis; the most common sites involved are the lung and bone. This report discusses the case of a 64-year-old male who presented with a mass in the left submandibular area. Biopsy was performed and histological analysis identified a poorly differentiated squamous cell carcinoma. After staging work up, it was concluded the patient had a maxillary sinus squamous cell carcinoma at clinical stage IVA. The patient received a left partial maxillectomy and left radical neck dissection followed by postoperative chemoradiotherapy. After three months of CRT, the patient developed a left adrenal gland metastasis without locoregional failure. The patient subsequently received a laparoscopic left adrenalectomy and the results of histological analysis revealed a poorly differentiated squamous cell carcinoma. Within one month of surgery, the patient had developed multiple metastases at the left adrenalectomy site and succumbed to the disease four months later. PMID- 29181178 TI - Development of lymphoma from the donor of haploidentical stem cell transplantation: A case report. AB - Post-transplantation lymphoproliferative disease (PTLD) is a serious complication following hematopoietic stem cell transplantation (HSCT). The majority of the cases develop during the first year after the transplantation and are associated with reactivation of the Epstein-Barr virus (EBV); the EBV-induced lymphoproliferation usually includes donor-derived B cells. We herein describe the case of a 28-year-old female patient who developed EBV-negative PTLD, namely diffuse large B-cell lymphoma (DLBCL), 6 months after receiving a haploidentical HSCT from her father. Chimerism analysis performed with XY fluorescence in situ hybridization revealed a B-cell PTLD originating from the donor. Unfortunately, the donor also developed DLBCL 380 days after donating progenitor cells, although he was hematologically normal at the time of donation. The present case demonstrated that disease transmitted from the donor may be a possible cause of PTLD. PMID- 29181179 TI - Efficacy of bendamustine on thrombocytopenia and hemolytic anemia secondary to CD5-positive B-cell lymphoma with massive splenomegaly in a patient with rheumatoid arthritis. AB - Chemotherapy for lymphoma may be avoided in the presence of coincident cytopenia. In case of immune cytopenia secondary to lymphoma, treatment of cytopenia is the same for primary cases, however, chemotherapy for lymphoma may be effective at the cost of severe hematological toxicity. The present study reports a complex case of thrombocytopenia and direct antiglobulin test-negative hemolytic anemia, thus mimicking Evans syndrome, secondary to cluster of differentiation 5-positive B-cell lymphoma with massive splenomegaly, in a patient suffering from rheumatoid arthritis for two decades. Treatment with prednisolone, high-dose dexamethasone, eltrombopag and rituximab for cytopenia were not effective. Chemotherapy with bendamustine subsequently resolved the cytopenia, additionally resulting in a complete remission of lymphoma. Thus, bendamustine may have a role in the management of lymphoma complicated with severe cytopenia. PMID- 29181180 TI - Comprehensive treatment of unresectable cardiac angiosarcoma: A case report and review of literature. AB - Cardiac angiosarcoma is a rare but lethal tumor that is difficult to diagnose and treat, due to its rapid local relapse and high incidence of systemic metastasis. The prognosis of cardiac angiosarcoma is dismal, with a mean life expectancy of only a few months. We herein report a case of unresectable angiosarcoma arising from the right atrium. The patient received first-line chemotherapy with weekly paclitaxel, and second-line therapy with vinorelbine and bevacizumab upon disease progression. The progression-free survival was 6 months and the overall survival was 7 months. The patient eventually succumbed to respiratory failure. A study of the present case and a review of the relevant literature suggest that treatment decisions for unresectable locally advanced or metastatic cardiac angiosarcoma are difficult, as the published literature on this disease mainly consists of case reports without sufficient data. Therefore, further clinical trials specific to the treatment of unresectable cardiac angiosarcoma are warranted. PMID- 29181181 TI - Adjuvant chemotherapy for patients with ypT0-2N0-category after neoadjuvant chemoradiotherapy for rectal cancer. AB - Locally advanced rectal cancer patients with ypT0-2N0 have good prognosis and may not require as many cycles of adjuvant chemotherapy as patients with a poor (ypT3 4 or N+) response. The aim of the present study was to evaluate the three-year disease-free and overall survival between patients with ypT0-2N0 rectal adenocarcinoma who received 0-3 cycles of 5-fluorouracil-based adjuvant chemotherapy and those who received >3 cycles. A total of 106 patients with locally advanced rectal cancer, classified as ypT0-2N0 after surgery at the Fudan University Shanghai Cancer Center (Shanghai, China) between 2006 and 2012, were identified. The patients were divided into two groups depending on the number of cycles of adjuvant chemotherapy: Group 1 received 0-3 cycles (n=32) and group 2 received >=4 cycles of adjuvant chemotherapy (n=74). The three-year disease-free survival and overall survival rates were 86.8 and 93.1% for group 1 (P=0.633), and 88.5 and 96.8% for group 2 (P=0.381). No statistically significant difference was observed between the two groups, suggesting that patients with ypT0-2N0 status may not require more than three cycles of post-operative chemotherapy. Further evaluation in prospective studies is urgently recommended. PMID- 29181182 TI - Solitary nodule of angiolymphoid hyperplasia with eosinophilia of the back masquerading as pyogenic granuloma. AB - Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare chronic inflammatory disorder of unknown etiology that most commonly presents as painless lymphadenopathy or subcutaneous masses in the head and neck region. The pathogenesis of the disease is not yet clear. The differential diagnosis is determined using characteristic histological features, such as significant vascular proliferation, lymphocytes and eosinophil inflammation in the dermis. Here is presented the case of a patient with a solitary nodule of ALHE masquerading as pyogenic granuloma (PG). A 47 year-old male patient was admitted with an isolated lump on the right side of the back, which had been present for ~6 months; the nodule appeared to have characteristics of PG and was ~1.8*1.0 cm2 in diameter. To the best of our knowledge, this is the first case report regarding ALHE arising in the back. The present report discusses the manifestation, histopathological features and treatment of the case. PMID- 29181183 TI - Internal fixation combined with bone grafting for large intraosseous calcaneal lipoma: A case report. AB - Intraosseous lipoma is a rare benign bone tumor that has been reported to occur in the calcaneus and long bones. The etiology of intraosseous lipoma is unknown, although several theories have been proposed. The majority of the cases of intraosseous calcaneal lipoma reported in the literature were localized in the anterior portion of the calcaneus and were treated by curettage and bone grafting. However, for larger lipomas, no specific treatment protocol has been developed to date. We herein present a rare case involving a large intraosseous lipoma of the calcaneus in a 36-year-old man following hindfoot trauma. The lesion was treated by decortication followed by bone grafting and internal fixation, a surgical approach that, to the best of our knowledge, has not been previously described in the literature. PMID- 29181184 TI - Claudin-1 expression in cervical cancer. AB - Claudin-1 is a tight junction protein that has been demonstrated to be involved in tumorigenesis and tumor progression in various types of solid tumors. In the present study, the protein expression of claudin-1 in squamous cervical cancer tissues obtained from 106 patients was analyzed by immunohistochemistry. In addition, the grade of claudin-1 expression was analyzed for associations with certain clinicopathological parameters. A significant overexpression of claudin-1 was detected in the tumor cells, when compared with that in the peritumoral stroma. There was no significant association between claudin-1 expression and FIGO stage, tumor size, grading or the appearance of distant metastases. Cervical cancer patients scoring positive for claudin-1 protein expression tended to exhibit more lymph node metastasis (28.3%), compared with claudin-1-negative patients (7.1%). Regarding overall survival, the results of the present study suggest a better prognosis for claudin-1-negative patients. In order to elucidate whether claudin-1 overexpression has a significant prognostic impact on squamous cervical cancer, further studies are required. PMID- 29181185 TI - Prognostic factors in patients with skeletal-related events at non-small-cell lung cancer diagnosis. AB - The aim of the present study was to detect prognostic factors in patients with skeletal-related events (SREs) and bone metastasis at the time of non-small-cell lung cancer (NSCLC) diagnosis. A total of 85 NSCLC patients were retrospectively enrolled, 47 (55.2%) of whom presented with SREs at the time of NSCLC diagnosis. Multivariate logistic regression analysis identified squamous cell carcinoma as a risk factor for SRE. Kaplan-Meier analysis demonstrated that there was no difference in the overall survival between the SRE and no SRE groups. Cox hazard model revealed that a higher Eastern Cooperative Oncology Group (ECOG) performance status (PS) score was a risk factor for poor prognosis, while surgery for bone metastasis and molecular-targeted therapy were factors for better prognosis in patients with SREs at the time of NSCLC diagnosis. Multivariate analysis revealed that a higher ECOG PS score and metastasis to the adrenal gland were risk factors for poor prognosis, while surgery for bone metastasis and molecular-targeted therapy were factors for better prognosis. Thus, while surgical treatment and molecular-targeted therapy appear to improve the prognosis of patients with bone metastasis at the time of NSCLC diagnosis, those with a higher ECOG PS score and adrenal metastasis may benefit more from radiotherapy or supportive care. PMID- 29181186 TI - Enhanced antitumor effects and improved immune status of dendritic cell and cytokine-induced killer cell infusion in advanced cancer patients. AB - Little progress has been made in the treatment of advanced cancer. Dendritic cells (DCs) plus cytokine-induced killer (CIK) cells have exhibited antitumor effects. Thus, the aim of the present study was to evaluate the clinical efficacy of DC-CIK cell treatment in patients with advanced cancer. A paired study including 57 patients treated with DC-CIK cells (DC-CIK group) and 33 patients treated with best supportive care alone (BSC group) was performed. The patients in the DC-CIK group were matched to those in the control group in terms of sex, age, tumor type and clinical stage. T-cell subsets were detected and overall survival (OS) was compared between the two groups. The results demonstrated that CD4+/CD25+ and CD8+/CD28- subsets significantly decreased following DC-CIK immunotherapy (P<0.05). The CD3+, CD3+/CD8+, CD8+/CD28+ and CD3+/CD56+ T-cell subsets were significantly increased in the DC-CIK group compared with the BSC group, while the CD8+/CD28- subset was significantly decreased. Univariate analysis demonstrated that a lower CD8+/CD28- and a higher CD8+/CD28+ ratio were associated with prolonged OS in advanced cancer patients. In addition, DC-CIK treatment administration, age (>60 vs. <60 years), clinical stage and the frequency of CIK treatment significantly affected the OS of patients in the DC CIK group. A CD8+/CD28- ratio of <21.12 was found to decrease the hazard ratio (HR) of OS to 0.50 [95% confidence interval (CI): 0.29-0.87] and a CD8+/CD28+ ratio >9.04 was found to decrease the HR of OS to 0.45 (95% CI: 0.21-0.98). No serious side effects were observed in the DC-CIK group. Taken together, these data indicate that DC-CIK infusions were able to change the ratios of the T-cell subsets, which increased the T helper cell and cytotoxic T lymphocyte subsets, while it decreased regulatory T lymphocyte subsets. Thus, this method of immunotherapy was found to improve the imbalance in the immune system and prolong the OS in patients with advanced cancer. PMID- 29181187 TI - Primary duodenal follicular lymphoma with late disseminated nodal relapse responsive to rituximab monotherapy: A case report. AB - Gastrointestinal follicular lymphoma is a rare malignancy accounting for only 1 3.6% of primary non-Hodgkin lymphomas of the gastrointestinal tract and it is a relatively new clinical entity that was recently classified as a distinct variant of systemic follicular lymphoma. Therefore, data regarding long-term outcome are currently lacking. In addition, a consensus on the management of this disease has not been established and treatment strategies are derived from systemic follicular lymphoma. We herein report the case of a 51-year-old female patient diagnosed with duodenal follicular lymphoma who had nodal relapse nearly 5 years after complete remission. The patient was successfully treated with a 4-week course of rituximab during the initial diagnosis and relapse. To the best of our knowledge, this is the first case report to demonstrate the efficacy of a 4-week course of rituximab during both the initial diagnosis and nodal relapse. The aim of this report was to add to the limited available data on the treatment of gastrointestinal follicular lymphoma. PMID- 29181188 TI - Intra-articular osteochondroma of the posteroinferior femoral neck associated with hip joint osteochondromatosis: A case report. AB - Osteochondromas are usually extra-articular lesions originating from the metaphysis of long bones. Intra-articular osteochondromas may also occur, causing pain and discomfort and restricting the range of motion. Osteochondromas of the femoral neck are intra-articular lesions that are difficult to access for surgical resection, particularly when located posteriorly. We herein present a rare case of an intra-articular osteochondroma involving the posteroinferior aspect of the femoral neck associated with secondary synovial osteochondromatosis (SOC) of the hip joint in a 25-year-old woman. Determining the optimal treatment was difficult due to the high risk of avascular necrosis (AVN) following surgical excision. The patient was successfully treated with arthroscopic surgery and she remained in good condition at 2 years postoperatively, with a full range of motion of the hip joint, and without signs of limping, recurrence of the SOC, or AVN of the femoral head. PMID- 29181189 TI - Expression and clinical significance of androgen receptor in bladder cancer: A meta-analysis. AB - Emerging evidence has demonstrated that androgen receptor (AR) is a promising therapeutic target for bladder cancer. However, the relationship between AR expression and its clinical significance remains controversial. The present in depth meta-analysis aimed to investigate the correlation between AR expression and clinicopathological features, as well as prognostic value in bladder cancer. A systematic search was performed from PubMed, Web of Knowledge, Embase and the Cochrane Central Search Library by January 2017. The correlation between AR expression and tumor stage, tumor grade, recurrence free survival and progression free survival for patients with bladder cancer was evaluated. A total of 12 relevant studies with 1,652 patient samples were included. AR expression positively correlated with low tumor grade [odds ratio (OR), 1.95; 95% confidence interval (CI), 1.36-2.81], low tumor stage (OR, 2.06; 95% CI, 1.02-4.16) and low recurrence rate [hazard ratio (HR), 0.48; 95% CI, 0.31-0.75] in Caucasian patients. While, its expression had no significant impact on cancer susceptibility (OR, 1.62; 95% CI, 0.19-13.72; P=0.44) and progression-free survival (HR, 1.20; 95% CI, 0.86-1.66; P=0.77). The present meta-analysis indicated that AR expression correlates with tumor grade, clinical stage and recurrence rates in the specified population and classification system. Further studies are required to determine the precise role of AR in bladder cancer. PMID- 29181190 TI - External quality assessment for EGFR mutations in Italy: improvements in performances over the time. AB - External quality assessment (EQA) schemes are essential procedures to assess the quality level of laboratories performing molecular testing of the epidermal growth factor receptor (EGFR) gene in non-small cell lung cancer. The Italian Association of Medical Oncology (AIOM) and the Italian Society of Pathology (SIAPEC-IAP) organise EGFR EQA programmes to ensure that the Italian laboratories achieve the quality standard levels required. Comparing the 2011, 2013 and 2015 EGFR EQA schemes, it was possible to observe improvements in the methodologies used and the outcomes. The use of direct sequencing was reduced from 78.7% in 2011 to only 14.1% in 2015, whereas the use of pyrosequencing and real-time PCR increased. The number of rounds in which centres using direct sequencing failed was significantly higher than the number of rounds that failed using other methods, both when analysing each single scheme and when combining the three EQAs together. In 2011 and 2013, about 29% of the participants failed the first phase of the programmes, compared with the 13% of centres failing in 2015, suggesting that the switch to more sensitive and robust methods could allow to increase the percentage of good performers. Although the molecular analyses are performed with good quality in Italy, the continuous education carried out by AIOM and SIAPEC IAP remains a fundamental tool to maintain this quality level. PMID- 29181191 TI - Anti-PD-1/anti-PD-L1 immunotherapy versus docetaxel for previously treated advanced non-small cell lung cancer: a systematic review and meta-analysis of randomised clinical trials. AB - Background: To compare the efficacy and toxicity of anti-programmed cell death receptor 1 (PD-1) and anti-programmed cell death ligand 1 (PD-L1) versus docetaxel in previously treated patients with advanced non-small cell lung cancer (NSCLC). Materials and methods: Phase III randomised clinical trials (RCTs) were identified after systematic review of databases and conference proceedings. A random-effect model was used to determine the pooled HR for overall survival (OS), progression-free survival (PFS) and duration of response. The pooled OR for overall response and treatment-related side effects were calculated using the inverse-variance method. Heterogeneity was measured using the tau2 and I2 statistics. Results: After the systematic review, we included four phase III RCTs (n=2737) in this meta-analysis. The use of anti-PD-1/anti-PD-L1 agents (atezolizumab, nivolumab and pembrolizumab) was associated with better OS in comparison with docetaxel alone (HR: 0.69; 95% CI 0.63 to 0.75; p<0.00001). Similarly, the PFS and duration of response was significantly longer for patients receiving immunotherapy (HR: 0.85; 95% CI 0.75 to 0.96; p=0.007 and HR:0.32; 95% CI 0.24 to 0.43; p<0.00001, respectively) versus single agent chemotherapy. The overall response rate was also higher for patients who received any anti-PD 1/anti-PD-L1 therapy in comparison with docetaxel (OR: 1.77; 95% CI 1.26 to 2.50; p=0.001). Regarding treatment-related side effects grade 3 or higher, patients who received immunotherapy experienced less events than patients allocated to docetaxel (OR: 0.19; 95% CI 0.12 to 0.30; p<0.00001). Conclusion: The use of anti PD-1/anti-PD-L1 therapy in patients with progressive advanced NSCLC is significantly better than the use of docetaxel in terms of OS, PFS, duration of response and overall response rate. PMID- 29181192 TI - Selecting PCR for the Diagnosis of Intestinal Parasitosis: Choice of Targets, Evaluation of In-House Assays, and Comparison with Commercial Kits. AB - Microscopy of stool samples is a labour-intensive and inaccurate technique for detection of intestinal parasites causing diarrhoea and replacement by PCR is attractive. Almost all cases of diarrhoea induced by parasites over a nine-year period in our laboratory were due to Giardia lamblia, Cryptosporidium species, or Entamoeba histolytica detected by microscopy. We evaluated and selected in-house singleplex real-time PCR (RT-PCR) assays for these pathogens in 99 stool samples from patients suspected of having intestinal parasitosis tested by microscopy. The strategy included a genus-specific PCR assay for C. parvum and C. hominis, with subsequent identification by a PCR that distinguishes between the two species. G. lamblia was detected in five and C. parvum in one out of 68 microscopy-negative samples. The performance of the in-house RT-PCR assays was compared to three commercially available multiplex test (MT-PCR) kit systems in 81 stool samples, collected in 28 microscopy-positive and 27 microscopy-negative samples from individuals suspected of intestinal parasitosis and in 26 samples from individuals without suspicion of parasitic infection. The in-house assays detected parasites in more samples from patients suspected of having parasitosis than did any of the kits. We conclude that commercial kits are targeting relevant parasites, but their performance may vary. PMID- 29181195 TI - Survey of Extent of Translation of Oral Healthcare Guidelines for ICU Patients into Clinical Practice by Nursing Staff. AB - Nosocomial infections in critically ill/ventilated patients result from bacterial load in oropharyngeal regions. Oral decontamination serves as the easiest effective means of controlling infections. Knowledge, attitude, and practices followed by healthcare personnel in intensive care settings need to be assessed to implement concrete measures in health-care. Survey questionnaire was constructed and implemented following its validation on seventy nursing and paramedical staff working in government and private intensive care units throughout Lucknow city. 21-item questionnaire consisted of three parts of seven questions each. 78% of respondents had knowledge regarding oral care and its importance in critical settings but 44% of respondents considered it to be unpleasant task. 36% of respondents claimed to have provided oral care to all patients in ICU. Uniform guidelines for translation of oral healthcare in ICU settings are not being implemented. Previous studies in literature from various geographic diverse regions also point out to similar lacunae. Based on present survey, most respondents were aware of importance of oral care with protocols covered in academic curriculum. Attitude towards oral care is positive but respondents feel a need for specialised training. Practice for oral care is not sufficient and needs improvement and proper implementation. PMID- 29181196 TI - 99mTc-Sestamibi/123I Subtraction SPECT/CT in Parathyroid Scintigraphy: Is Additional Pinhole Imaging Useful? AB - Objectives: This retrospective study evaluated whether the use of additional anterior 99mTc-sestamibi/123I pinhole imaging improves the outcome of 99mTc sestamibi/123I subtraction SPECT/CT in parathyroid scintigraphy (PS). Materials and Methods: PS using simultaneous dual-isotope subtraction methods and an acquisition protocol combining SPECT/CT and planar pinhole imaging was performed for 175 patients with primary or secondary hyperparathyroidism. All patients who proceeded to surgery with complete postsurgery laboratory findings were included in this study (n = 94). SPECT/CT images alone and combined with pinhole images were evaluated. Results: There were 111 enlarged parathyroid glands of which 104 and 108 glands were correctly visualized by SPECT/CT (seven false positives) or SPECT/CT with pinhole (three false positives), respectively. Both sensitivity and specificity were higher with combined SPECT/CT with pinhole than with SPECT/CT alone (97% versus 94% and 99% versus 98%, resp., not significant). The false positive rate was 6% with SPECT/CT and decreased to 3% using combined SPECT/CT with pinhole. Conclusion: 99mTc-sestamibi/123I subtraction SPECT/CT is a highly sensitive and specific protocol for PS. The use of additional anterior pinhole imaging increases both sensitivity and specificity of PS, although this increase is not statistically significant. PMID- 29181197 TI - Application of Real-Time 3D Navigation System in CT-Guided Percutaneous Interventional Procedures: A Feasibility Study. AB - Introduction: To evaluate the accuracy of a quantitative 3D navigation system for CT-guided interventional procedures in a two-part study. Materials and Methods: Twenty-two procedures were performed in abdominal and thoracic phantoms. Accuracies of the 3D anatomy map registration and navigation were evaluated. Time used for the navigated procedures was recorded. In the IRB approved clinical evaluation, 21 patients scheduled for CT-guided thoracic and hepatic biopsy and ablations were recruited. CT-guided procedures were performed without following the 3D navigation display. Accuracy of navigation as well as workflow fitness of the system was evaluated. Results: In phantoms, the average 3D anatomy map registration error was 1.79 mm. The average navigated needle placement accuracy for one-pass and two-pass procedures, respectively, was 2.0 +/- 0.7 mm and 2.8 +/ 1.1 mm in the liver and 2.7 +/- 1.7 mm and 3.0 +/- 1.4 mm in the lung. The average accuracy of the 3D navigation system in human subjects was 4.6 mm +/- 3.1 for all procedures. The system fits the existing workflow of CT-guided interventions with minimum impact. Conclusion: A 3D navigation system can be performed along the existing workflow and has the potential to navigate precision needle placement in CT-guided interventional procedures. PMID- 29181194 TI - Physiological Roles of DNA Double-Strand Breaks. AB - Genomic integrity is constantly threatened by sources of DNA damage, internal and external alike. Among the most cytotoxic lesions is the DNA double-strand break (DSB) which arises from the cleavage of both strands of the double helix. Cells boast a considerable set of defences to both prevent and repair these breaks and drugs which derail these processes represent an important category of anticancer therapeutics. And yet, bizarrely, cells deploy this very machinery for the intentional and calculated disruption of genomic integrity, harnessing potentially destructive DSBs in delicate genetic transactions. Under tight spatiotemporal regulation, DSBs serve as a tool for genetic modification, widely used across cellular biology to generate diverse functionalities, ranging from the fundamental upkeep of DNA replication, transcription, and the chromatin landscape to the diversification of immunity and the germline. Growing evidence points to a role of aberrant DSB physiology in human disease and an understanding of these processes may both inform the design of new therapeutic strategies and reduce off-target effects of existing drugs. Here, we review the wide-ranging roles of physiological DSBs and the emerging network of their multilateral regulation to consider how the cell is able to harness DNA breaks as a critical biochemical tool. PMID- 29181198 TI - Effects of Long-Term Cultivation on Medium with Alpha-Ketoglutarate Supplementation on Metabolic Processes of Saccharomyces cerevisiae. AB - During last years, alpha-ketoglutarate (AKG), an important intermediate in the Krebs cycle, has been intensively studied as a dietary supplement with stress protective and potential antiaging effects. Here, we examined the effects of exogenous AKG on metabolic processes and survival of yeast Saccharomyces cerevisiae during long-term cultivation. Growth on AKG had no effect on the total cell number but increased the number of reproductively active cells at the late days of cultivation (from day 7 to day 15). A gradual increase in levels of total protein, glycogen, and trehalose was found over 7-day cultivation with more pronounced effects in AKG-grown cells. In control cells, metabolic activity and the activities of superoxide dismutase and catalase decreased, whereas levels of carbonyl proteins and low-molecular-mass thiols increased during 7-day cultivation. This suggests development of oxidative stress in stationary phase cells. Meanwhile, stationary phase cells cultured on AKG possessed higher levels of low-molecular-mass thiols and lower levels of carbonyl proteins and alpha dicarbonyl compounds when compared to control ones. Collectively, higher levels of storage carbohydrates and an activation of antioxidant defense with diminishing oxidative protein damage can prevent a loss of reproductive ability in yeast cells during long-term cultivation on AKG-supplemented medium. PMID- 29181199 TI - The Effects of Aerobic Exercise on the Recovery of Walking Ability and Neuroplasticity in People with Multiple Sclerosis: A Systematic Review of Animal and Clinical Studies. AB - Introduction: Walking is of high priority for people with multiple sclerosis (PwMS). It remains unclear whether aerobic exercise can improve walking ability and upregulate neurotrophins. This review aims to consolidate evidence to develop optimal aerobic training parameters to enhance walking outcomes and neuroplasticity in PwMS. Methods: Clinical studies examining aerobic exercise for >=3 weeks, having outcomes on walking with or without neurotrophic markers, were included. Studies utilizing animal models of MS were included if they employed aerobic exercise with outcomes on neurological recovery and neurotrophins. From a total of 1783 articles, 12 clinical and 5 animal studies were included. Results: Eleven clinical studies reported improvements in walking ability. Only two clinical studies evaluated both walking and neurotrophins, and neither found an increase in neurotrophins despite improvements in walking. Patients with significant walking impairments were underrepresented. Long-term follow-up revealed mixed results. Two animal studies reported a positive change in both neurological recovery and neurotrophins. Conclusion: Aerobic exercise improves walking ability in PwMS. Gains are not consistently maintained at 2- to 9-month follow-up. Studies examining levels of neurotrophins are inconclusive, necessitating further research. Aerobic exercise enhances both neurological recovery and neurotrophins in animal studies when started 2 weeks before induction of MS. PMID- 29181193 TI - In What Ways Do Synthetic Nucleotides and Natural Base Lesions Alter the Structural Stability of G-Quadruplex Nucleic Acids? AB - Synthetic analogs of natural nucleotides have long been utilized for structural studies of canonical and noncanonical nucleic acids, including the extensively investigated polymorphic G-quadruplexes (GQs). Dependence on the sequence and nucleotide modifications of the folding landscape of GQs has been reviewed by several recent studies. Here, an overview is compiled on the thermodynamic stability of the modified GQ folds and on how the stereochemical preferences of more than 70 synthetic and natural derivatives of nucleotides substituting for natural ones determine the stability as well as the conformation. Groups of nucleotide analogs only stabilize or only destabilize the GQ, while the majority of analogs alter the GQ stability in both ways. This depends on the preferred syn or anti N-glycosidic linkage of the modified building blocks, the position of substitution, and the folding architecture of the native GQ. Natural base lesions and epigenetic modifications of GQs explored so far also stabilize or destabilize the GQ assemblies. Learning the effect of synthetic nucleotide analogs on the stability of GQs can assist in engineering a required stable GQ topology, and exploring the in vitro action of the single and clustered natural base damage on GQ architectures may provide indications for the cellular events. PMID- 29181200 TI - Epidemiology of C2 Fractures in the 21st Century: A National Registry Cohort Study of 6,370 Patients from 1997 to 2014. AB - Objective: C2 fractures are a common injury in the elderly population. Treatment is often complicated due to osteoporosis and patient comorbidity. This study aims to investigate the incidence and treatment trend of C2 fractures in Sweden. Methods: Patients with the principal and secondary diagnosis of fracture of the second vertebrae (ICD-10: S12.1) between 1997 and 2014 were identified in the Swedish National Patient Registry (NPR). Results: Between 1997 and 2014, 6,370 patients with a C2 fracture (51% male; age: 72 +/- 18) were identified in the NPR. The incidence of C2 fractures increased from 3 to 6 per 100,000 (r = 0.94; p < 0.01), mainly due to an increase of incidence in the geriatric subgroup (>=70 years). The percentage of surgically treated patients decreased from 1997 to 2014 (r = -0.80; p < 0.01). Younger age, male gender, spinal cord injury, and earlier year of admission were associated with surgical treatment assignment. Discussion: This study documents a rising incidence of C2 fractures in the elderly during the last two decades in Sweden. Greater awareness of fractures, improved diagnostics, coding, and a higher activity level of the patients are plausible causes. The declining trend of surgical treatment warrants further study. PMID- 29181201 TI - Sleep in the Postpartum: Characteristics of First-Time, Healthy Mothers. AB - Goals for the present study were to (a) describe the sleep of healthy new mothers over a 6-month postpartum period, (b) examine how sleep quality relates to daytime levels of fatigue and sleepiness, and (c) evaluate the relationship between mothers' and infants' sleep parameters. The sample consisted of 37 healthy, partnered, first-time mothers who had experienced full-term vaginal birth and had a healthy infant. We investigated infants' sleep parameters and mothers' sleep, mood, and daytime functioning 2 and 6 months postpartum. We found that at 2 months postpartum, mothers reported sleeping 6 hours at night and just under one hour during the day. Despite relatively frequent nocturnal awakenings, mothers experienced minimal insomnia, nonrefreshing sleep, anxiety, depression, daytime sleepiness, or fatigue at either 2 or 6 months. The most robust relationship between mothers' and infants' sleep was in the number of nocturnal sleep-wake episodes. Of note is that none of the infant sleep parameters was related to mothers' anxiety, depression, fatigue, sleepiness, or nonrefreshing sleep at either time period. Our results indicate that (1) selected low risk new mothers are resilient in terms of sleep quality, daytime functioning, and mood and (2) these are independent of their infants' sleep parameters. PMID- 29181203 TI - Conducting Prolonged General Anesthesia without Intravenous Access in a Child with Hypoplastic Left Heart Syndrome. AB - Children with chronic medical conditions often need multiple intravenous (IV) access instances during their hospitalizations, both peripheral and central. Obtaining a working IV in this patient population undergoing general anesthesia can be challenging. In our case report, we describe a method of administering general anesthesia in an infant with partially repaired hypoplastic left heart syndrome without IV access. PMID- 29181204 TI - A Case of Invasive Pneumococcal Infection with Septic Shock and Rare Complications. AB - Invasive pneumococcus is a serious illness with potentially devastating outcomes. A 64-year-old female with a medical history of psoriatic arthritis and diabetes was transferred from an outside hospital for ventilator dependent respiratory failure and altered mental status. She initially presented with worsening back pain and was found to have leukocytosis with bandemia and acute renal failure but she was in septic shock upon arrival to our tertiary care center. Her blood cultures grew Streptococcus pneumoniae and MRI of the brain revealed pus within the posterior lateral ventricles and multiple infarcts. MRI of the spine revealed a psoas abscess. Transesophageal echocardiogram revealed mitral valve vegetation and her right eye developed endogenous endophthalmitis. She was treated with intravenous and intravitreal antibiotics and underwent drainage of the abscess with no improvement in mental status. Repeat imaging revealed multiple new thalamic, basal ganglia, and parietal lobe infarcts likely from septic emboli. After a protracted ICU stay, the patient's family opted for comfort care. The incidence of invasive pneumococcal infections has declined rapidly since the advent of antibiotics and vaccines. With the growing incidence of antibiotic resistance as well as the emergence of new immunomodulating drugs for various pathologies, there is a concern that invasive infections will reemerge. Ventriculitis and endogenous endophthalmitis are very rare complications of pneumococcal bacteremia. PMID- 29181205 TI - Basidiobolomycosis Simulating a Mycobacterium ulcerans Infection in a Togolese Rural Child. AB - Background: Basidiobolomycosis is a deep mycosis which preferentially affects rural young people in tropical countries. We report an atypical case, with multiple ulcers, simulating a Buruli ulcer. Case Report: A 5-year-old boy, living in a rural area, was seen for ulcers on the buttocks and at the back and right flank that had been in progress for 4 months. On examination, we found an infiltrated plaque with sharp edges, little painful, located on the buttocks, back, and the right flank. On this plaque, there were multiple ulcers with polycyclic contours and fibrinous bottom. There were inguinal inflammatory lymph nodes. The patient had an altered general condition. Examination of other organs was normal. The diagnosis of Buruli ulcer was evoked first; the search for Mycobacterium ulcerans by polymerase chain reaction was negative. Histology test performed revealed hypodermic granulomatous inflammation with predominant macrophage and eosinophils. The mycological culture was not done. The child was treated successfully with ketoconazole (10 mg/kg/day) during eight weeks. Discussion: Our observation shows great clinical and epidemiological similarities between basidiobolomycosis and Buruli ulcer. It confirms the efficacy of ketoconazole in severe basidiobolomycosis infection with alteration of general condition. Histopathology is very important for differential diagnosis between these two diseases. PMID- 29181206 TI - Atypical Histiocyte-Rich Sweet's Syndrome. AB - Sweet's Syndrome is a rare neutrophilic dermatosis thought to be a result of immune dysregulation occurring in the setting of drug exposure, recent infection, pregnancy, and underlying malignancy or idiopathic with specific and widely accepted diagnostic criteria established in the literature. Other organ systems can be involved with varying degrees of severity. An unusual case of Sweet's Syndrome associated with myopericarditis, acral involvement, and atypical histological findings with predominance of histiocytes is described here. PMID- 29181207 TI - Mycoplasma Pneumonia: An Unrecognized Cause of Fever of Unknown Origin in an Adult. AB - A 26-year-old female was admitted for fever of unknown origin (FUO), headaches, left ankle edema, and a lower extremity rash consistent with erythema nodosum. She had no respiratory symptoms or family history of autoimmune diseases. A chest X-ray was negative for pneumonia or hilar adenopathy. Extensive autoimmune workup was negative. A chest, abdomen, and pelvis computed tomography scan was unremarkable and laboratory studies revealed no source of infection. On hospital day 5, the patient developed a mild productive cough. Her Mycoplasma pneumonia (MP) IgM was high, confirming the diagnosis of MP induced FUO. She was started on azithromycin 500 mg daily and within 24 hours her fevers and headaches resolved. Her left ankle edema and EN gradually improved over a course of a few weeks. This case report highlights the need for MP testing in the evaluation of fever of unknown origin, even in the absence of pulmonary manifestations. PMID- 29181202 TI - Neural Plasticity Is Involved in Physiological Sleep, Depressive Sleep Disturbances, and Antidepressant Treatments. AB - Depression, which is characterized by a pervasive and persistent low mood and anhedonia, greatly impacts patients, their families, and society. The associated and recurring sleep disturbances further reduce patient's quality of life. However, therapeutic sleep deprivation has been regarded as a rapid and robust antidepressant treatment for several decades, which suggests a complicated role of sleep in development of depression. Changes in neural plasticity are observed during physiological sleep, therapeutic sleep deprivation, and depression. This correlation might help us to understand better the mechanism underlying development of depression and the role of sleep. In this review, we first introduce the structure of sleep and the facilitated neural plasticity caused by physiological sleep. Then, we introduce sleep disturbances and changes in plasticity in patients with depression. Finally, the effects and mechanisms of antidepressants and therapeutic sleep deprivation on neural plasticity are discussed. PMID- 29181208 TI - Large Retroperitoneal Haemorrhage Following Cyst Rupture in a Patient with Autosomal Dominant Polycystic Kidney Disease. AB - The complications of autosomal dominant polycystic kidney disease (ADPKD) include cyst rupture and haemorrhage leading to loin pain and frank haematuria. Risk factors include large kidney volume, hypertension, and renal impairment. We present a case of a young male who, following trauma to the kidney, had a life threatening bleed from his polycystic kidney. The case was initially treated with fluid resuscitation and blood transfusion but necessitated radiological embolization of bleeding source to control the blood loss. We review the risk factors and management of cyst haemorrhage in patients with ADPKD. Contact sports should be avoided as cyst rupture can lead to severe life threatening haemorrhage. PMID- 29181209 TI - Ureteropelvic Junction Obstruction and Parathyroid Adenoma: Coincidence or Link? AB - Congenital ureteropelvic junction obstruction (UPJO) is the most common cause of upper urinary tract obstruction in children. It is generally diagnosed in the routine work-up during antenatal period and is characterized by spontaneous recovery. It can be associated with urolithiasis; hence further investigation should be carried out. We report the case of a 15-year-old boy, who is known to have right UPJO, presented with right renal colic and discovered to have bilateral kidney stones. Further studies showed primary hyperparathyroidism and genetic analysis revealed a CDC73 mutation (initially HRPT2). We believe that association of UPJO and PHPT is a rare coincidence that can be linked. Careful work-up of children with UPJO and urolithiasis is recommended to exclude an underlying metabolic disease. Surgical correction can be evitable as treatment of the primary cause can lead to complete dissolution of kidney stones and improvement of the medical condition. PMID- 29181210 TI - Bilateral Tubal Pregnancy without Known Risk Factor. AB - Spontaneous bilateral ectopic gestation is very rare. The authors report a case diagnosed and taken care of at Yalgado Ouedraogo Teaching Hospital, Ouagadougou. It was a 30-year-old patient with no known pathological history. She had presented at the obstetric emergencies with a state of hypovolemic shock by haemoperitoneum with digestive disorders, pelvic pain, vaginal bleeding, and a mention of delayed menstruation. The ultrasound coupled with the urinary immunological pregnancy test confirmed the diagnosis of ruptured ectopic pregnancy and a bilateral form was suspected. A laparotomy in emergency confirmed the diagnosis of bilateral ectopic gestation with a right ampullary unruptured pregnancy and a left isthmic ruptured gestation. A bilateral salpingectomy was performed and counseling was made for the use of medical help of procreation in case of future need of pregnancy. PMID- 29181211 TI - Placenta Percreta in First Trimester after Multiple Rounds of Failed Medical Management for a Missed Abortion. AB - Background: The detection of a morbidly adherent placenta (MAP) in the first trimester is rare. Risk factors such as multiparity, advanced maternal age, prior cesarean delivery, prior myomectomy, placenta previa, or previous uterine evacuation place patients at a higher risk for having abnormal placental implantation. If these patients have a first trimester missed abortion and fail medical management, it is important that providers have a heightened suspicion for a MAP. Case: A 24-year-old G4P3003 with 3 prior cesarean deliveries underwent multiple rounds of failed medical management for a missed abortion. She had a dilation and curettage that was complicated by a significant hemorrhage and ultimately required an urgent hysterectomy. Conclusion: When patients fail medical management for a missed abortion, providers need to assess the patient's risk factors for a MAP. If risk factors are present, a series of specific evaluations should be triggered to rule out a MAP and help further guide management. Early diagnosis of a MAP allows providers to coordinate a multidisciplinary treatment approach and thoroughly counsel patients. Ensuring adequate resources and personnel at a tertiary hospital is essential to provide the highest quality of care and improve outcomes. PMID- 29181212 TI - Uncommon BRAF Mutations Associated with Durable Response to Immunotherapy in Patients with Metastatic Melanoma. AB - Melanoma is a disease process which has been increasing in incidence over the past three decades and metastatic melanoma carries a poor prognosis. Through genetic studies of this disease, it has been determined that the BRAF V600 mutation plays a major role in the pathophysiology of the disease and this has led to the utilization of targeted therapy (BRAF and MEK inhibitors) in its treatment. Other BRAF mutations (non-V600 mutations) are rare in melanoma and targeted therapy is not indicated for patients with these mutations due to reduced response rates. An emerging option for metastatic melanoma with uncommon BRAF mutations is immunotherapy using checkpoint inhibitors such as PD-1 inhibitors or CTLA-4 inhibitors. Currently, it is unknown how patients with BRAF non-V600 mutations respond to immunotherapy. This report will examine the effect of immunotherapy on two distinct metastatic melanoma patients, each with uncommon BRAF mutations, occurring outside the V600 locus (E586K and G469E). These patients were noted to have a durable, complete response when treated with immunotherapy and continue to exhibit a response 9 and 15 months after discontinuing therapy. Further research and clinical trials are needed to study patients with uncommon BRAF mutations and the potential therapeutic benefit of immunotherapy. PMID- 29181213 TI - Therapeutic Management of a Substantial Pelvic Aneurysmatic Bone Cyst Including the Off-Label Use of Denosumab in a 35-Year-Old Female Patient. AB - Aneurysmal bone cysts (ABC) are benign bone tumors, which are highly vascularized. The main course of treatment is curettage followed by bone grafting or cement insertion. Still recurrence remains a main problem for patients. Denosumab is a monoclonal antibody, which acts as an inhibitor of the RANK/RANKL pathway, diminishing bone turnover. Recent case reports have shown that Denosumab can be a promising therapeutic agent for people suffering from therapy-resistant ABC. We report the case of a 35-year-old female patient presenting with a pronounced ABC of the pelvis. Since the tumor was inoperable, Denosumab was administered, leading to a significant shrinkage of the lesion, which allowed surgical intervention. Upon recurrence, Denosumab was restarted putting the patient once more into remission. Follow-up was four years overall with a clinical and radiological stable disease for fifteen months after final discontinuation of the monoclonal antibody. Therefore, our case further underlines the potential of Denosumab in the treatment of ABC. PMID- 29181214 TI - Atypical Presentation of Sjogren-Larsson Syndrome. AB - Sjogren-Larsson syndrome is a rare neurocutaneous disorder characterized by ichthyosis, spastic diplegia or tetraplegia, and intellectual disability. Herein, we describe a case of a Greek patient with ichthyosis and spasticity of the legs but with normal intelligence (IQ 95). This syndrome should be suspected when a child presents with ichthyosis and spastic diplegia or tetraplegia, even if intelligence is normal. PMID- 29181215 TI - Electroconvulsive Therapy in Functional Hallucination: Scope and Challenges. AB - Functional hallucinations are hallucinations triggered by a stimulus in the same modality and cooccur with it. They are rare in occurrence; however, their rarity has no significance as psychopathology till date. Also, very little is known about the treatment of such hallucinations. Electroconvulsive therapy (ECT) has been tested for several psychiatric illnesses and has a few relative contraindications; however, it has not previously been used in treating functional hallucinations. We report on a female patient with paranoid schizophrenia who experienced functional hallucinations continuously despite the use of adequate risperidone, which controlled other symptoms. She was treated with ECT which resolved the functional hallucinations. The case highlights the need to ponder on the significance of the phenomenon as well as treatment of this psychopathology by ECT. It also underscores ECT as a treatment option for this kind of hallucination. PMID- 29181216 TI - Endovascular Repair with a Stent Graft in a Patient with Aortoduodenal Fistula after Radiation Therapy. AB - Primary aortoduodenal fistula (ADF) is a direct communication between the abdominal aorta and the gastrointestinal tract without any previous vascular intervention and represents a rare but critical cause of repeated and massive gastrointestinal bleeding. Primary ADF often occurs as a result of atherosclerotic aneurysm and infection, but ADF involving a normal-size aorta is rare; furthermore, ADF related to radiation therapy is extremely rare. We present the case of a 56-year-old man with a history of bowel obstruction due to radiation enteritis who was admitted with severe hematemesis and hemorrhagic shock. Gastroduodenal endoscopy and contrast-enhanced computed tomography findings were unremarkable. Aortoduodenal fistula was suspected based on the diffuse calcification of the abdominal aorta confined to the radiation field and the presence of an aortoduodenal communication on angiography. Endovascular repair with a stent graft seemed to be a safer option than open surgery and was suited to the rapid control of bleeding from ADF because of the patients' unstable hemodynamic state and the presence of intestinal adhesions. The fistula was successfully sealed by endovascular stent graft placement. Hematemesis did not recur postoperatively and anemia gradually improved. The patient died from pneumonia 33 days later. PMID- 29181217 TI - Traumatic Haemorrhagic Cervical Lymphadenopathy with Underlying Infectious Mononucleosis. AB - A 16-year-old male presented to the Emergency Department with a painful 3 * 3 cm left-sided neck swelling six hours following blunt trauma to the neck from a heavy swinging door. A CT angiogram was performed which revealed a large haemorrhagic lymph node as well as generalised cervical lymphadenopathy. The patient was eventually diagnosed with infectious mononucleosis. This case report describes a rare case of traumatic haemorrhagic cervical lymphadenopathy with an underlying diagnosis of infectious mononucleosis. PMID- 29181218 TI - Superinfection of a Dead Hepatic Echinococcal Cyst with a Cutaneous Fistulization. AB - Cystic echinococcosis (CE), also known as "hydatid disease" (HD), is a zoonotic infection caused by the larval stage of Echinococcus granulosus, which infects humans as intermediate hosts through the orofecal route. Carried by the intestinal venous blood, the embryos released by the eggs of the tapeworms can reach every organ, especially the liver, turning into a hydatid cyst. Usually asymptomatic, the cysts can be incidentally detected through radiological examinations performed for other reasons. We show an unusual case of superinfection of a hydatid cyst with typical radiological features of inactivity (WHO-type CE5) with an even rarer skin fistulization passing through a subcutaneous-abdominal abscess involving the right iliac muscle. PMID- 29181220 TI - Angio-SealTM Embolization: A Rare Etiology of an Acute Distal Limb Ischemia. AB - We herein report a serious vascular complication of diagnostic cardiac catheterization due to an embolization of an Angio-Seal closure device causing acute lower limb ischemia. The Angio-Seal was deployed via the right femoral artery following the catheterization which embolized several hours later to the right popliteal artery. Fogarty embolectomy restored perfusion to the right lower limb; however, compartment syndrome subsequently developed which required evacuation of a hematoma and repair of right popliteal artery. PMID- 29181219 TI - Idiopathic Giant Hepatic Artery Pseudoaneurysm. AB - Hepatic artery pseudoaneurysm (HAP) incidence is rising due to more common use of endoscopic and percutaneous hepatic interventions. HAP is potentially fatal, as it could lead to sudden life-threatening hemorrhage. HAP can be intrahepatic or extrahepatic. On computed tomography angiogram (CTA) and magnetic resonance angiogram (MRA), HAP follows blood pool on multiphasic examination, with brisk arterial enhancement that washes out, similar to the abdominal aorta on later phases. We present a case of idiopathic giant HAP in an 82-year-old male. Currently, angioembolization is replacing surgery as the initial modality of choice for management of this condition. PMID- 29181221 TI - Electroanalytical Sensing of Bromides Using Radiolytically Synthesized Silver Nanoparticle Electrocatalysts. AB - Monitoring bromides (Br-) is of crucial importance since bromates, potential human carcinogens, are formed during ozonation of water containing bromides in concentrations >100 MUg L-1. Within this study, silver (Ag) and four carbon supported Ag catalysts were synthesized by the gamma-radiation method and their morphology and structure examined using transmission electron microscopy, X-ray diffraction, and UV-Vis analysis. The nanocatalysts were tested for Br- sensing in aqueous media using cyclic voltammetry. All five Ag materials exhibited electroactivity for sensing of Br- ions, with pure Ag catalyst giving the best response to Br- ions presence in terms of the lowest limit of detection. Sensing of bromides was also explored in tap water after addition of bromides suggesting that herein prepared catalysts could be used for bromides detection in real samples. Furthermore, sensing of other halogen ions, namely, chlorides and iodides, was examined, and response due to chloride presence was recorded. PMID- 29181222 TI - Validation of an UHPLC-MS/MS Method for Screening of Antimicrobial Residues in Eggs and Their Application to Analyses of Eggs from Laying Hens Subjected to Pharmacological Treatment. AB - A multiresidue method by UHPLC/MS-MS was optimized and validated for the screening and semiquantitative detection of antimicrobials residues from tetracyclines, aminoglycosides, quinolones, lincosamides, beta-lactams, sulfonamides, and macrolides families in eggs. A qualitative approach was used to ensure adequate sensitivity to detect residues at the level of interest, defined as maximum residue limit (MRL), or less. The applicability of the methods was assessed by analyzing egg samples from hens that had been subjected to pharmacological treatment with neomycin, enrofloxacin, lincomycin, oxytetracycline, and doxycycline during five days and after discontinuation of medication (10 days). The method was adequate for screening all studied analytes in eggs, since the performance parameters ensured a false-compliant rate below or equal to 5%, except for flumequine. In the analyses of eggs from laying hens subjected to pharmacological treatment, all antimicrobial residues were detected throughout the experimental period, even after discontinuation of medication, except for neomycin, demonstrating the applicability of the method for analyses of antimicrobial residues in eggs. PMID- 29181223 TI - The Evidence of Cooperative Binding of a Ligand to G4 DNA. AB - Intrinsic constants of the ligand binding with G4 DNA (guanine-rich DNA sequence) using quantitative standards can be convenient providing the assessment for elucidating the possibility of such structures participation in biochemical processes. In the present communication, the hard + soft modelling approach to calculate intrinsic constants of a ligand binding with short DNA molecule, particularly such as G4 DNA, has been proposed. The suggested approach has focused upon the quantitative evaluating of a mutual influence between sites and between bound ligands. The cross-validation between a new hard + soft modelling and conventional stepwise complex formation algorithm has been conducted. A number of simulated examples will illustrate the methodology. The experimental mole-ratio titration of TMPyP4 by G4 DNA [(CG3)2CGC(AG3)2G] has been reexamined. The [(CG3)2CGC(AG3)2G] that folds from a G-rich sequence found in the promoter region of c-kit oncogene can be considered as a molecule with two equivalent mutually influence binding sites. PMID- 29181224 TI - Application of 19F NMR Spectroscopy for Content Determination of Fluorinated Pharmaceuticals. AB - A simple, rapid, and selective quantitative nuclear magnetic resonance spectroscopic method was evaluated for the determination of the content of fluorinated pharmaceuticals. 19F NMR spectra were either obtained in dimethylsulfoxide-d6 or aqueous buffer, using trifluoroacetic acid as internal standard. Quantification of 13 fluorine-containing pharmaceuticals spanning various pharmacological classes was accomplished using the proposed method. The method was found to be fit for purpose (interday precision 1.2% relative standard deviation) and may thus be applied for routine analysis and quality control of fluorine-containing pharmaceuticals due to its simplicity, nondestructive sample measurement, reliability, and high specificity. Therefore, 19F NMR may serve as a suitable analytical tool for the identification and selective determination of fluorinated pharmaceuticals used as reference materials and bulk samples. PMID- 29181225 TI - Assessment of the Efficacy of Home Remedial Methods to Improve Drinking Water Quality in Two Major Aquifer Systems in Jaffna Peninsula, Sri Lanka. AB - Chunnakam and Vadamaradchi are two major aquifer systems in Jaffna Peninsula, Sri Lanka. This study was performed to compare water quality in the domestic wells in these aquifers and to assess the efficacy of household water treatments for treating contaminated water. Replicate well water samples were collected from each aquifer and pH, dissolved oxygen (DO), conductivity, total dissolved solids (TDS), salinity, temperature, total solids (TS), total hardness (TH), chemical oxygen demand (COD), oil and grease (OG), nitrate N (N), and total phosphate (TP) were measured. The sampled water from the domestic wells was filtered through commercial mineral filter and Moringa oleifera leaf powder and boiled at 100 degrees C for 10 minutes and the TH, OG, N, and TP were measured. Both OG and N in Chunnakam were significantly higher and the DO were significantly lower than those of Vadamaradchi. TH, N, and OG of some wells exceeded the drinking water quality standards established by Sri Lanka Standards Institution. Moringa oleifera leaf powder filtration reduced N significantly and filtering through commercial mineral filter reduced OG, TH, and N significantly. Boiling at 100 degrees C could remove TH significantly but may cause significant increase in N which might result in health impacts. PMID- 29181226 TI - Blood Safety Status in WHO African Region Countries: Lessons Learnt from Mauritius. AB - In 2001, the WHO Office for Africa adopted a strategy for blood safety defining four targets. This paper describes the progress made by Mauritius in the implementation of this strategy. The blood safety indicators were collected and compared with the norms recommended by WHO. The country has formulated its blood policy and developed a strategic plan for its implementation since 2004. The total number of blood donations increased from 31,228 in 2002 to 43,742 in 2016, giving an annual blood collection rate evolving from 26.3 per 1000 inhabitants in 2002 to 34.2 per 1000 inhabitants in 2016. The percentage of voluntary donations rose from 60% to 82.5%. Since 2002, all the blood units collected have been tested for the mandatory infectious markers. The Blood Transfusion Service has been certified ISO2008-9001 and nucleic acid testing has been introduced. The preparation of blood components increased from 60% to 98.2%. The most transfused blood components were red cell concentrates, platelet concentrates, and fresh frozen plasma. In addition to transfusion activities, there were other departments performing antenatal serology, tissue typing, special investigations, and reagent preparation. Despite the progress made, some challenges remain, namely, legal framework and haemovigilance system. A regulatory system for blood needs to be established.

PMID- 29181228 TI - Knowledge of warning signs, presenting symptoms and risk factors of coronary heart disease among the population of Dubai and Northern Emirates in UAE: a cross sectional study. AB - Background: To evaluate the level of knowledge regarding warning signs, presenting symptoms and risk factors associated with coronary heart disease (CHD) among population of Dubai and Northern Emirates in UAE. Materials and Methods: A cross sectional survey of 1367 residents of Dubai and Northern Emirates was conducted using a self-administered questionnaire. Results: Respondents were classified into two groups: Young Adult Population (YAP; 18-24 years of age) and General Population (GP; 25 years and older). Majority of participants were males (56.7%) and of South Asian (57.5%) or Middle-Eastern (30.8%) ethnicity. Regarding presenting symptoms of CHD, chest pain was identified by around 80% of population, whereas pain in the left shoulder was recognized by 61% of GP and 44% of YAP. Atypical symptoms were poorly identified. Regarding risk factors, only one-fourth population knew that males were at higher risk compared to premenopausal females. Few knew that the risk increases in females after menopause and that the risk is higher for females who smoke and use oral contraceptives. 62% knew that the survivors of a heart attack are at high risk of recurrences. Except for tobacco smoke, hypercholesterolemia and hypertension, knowledge of other risk factors was not satisfactory. Older adults and females had comparatively higher level of knowledge. Conclusion: Knowledge level of many of the symptoms and risk factors of CHD is unsatisfactory. There is, therefore, a need to increase the awareness in the population of UAE. The knowledge gaps identified through this study can be addressed through health campaigns to increase the awareness about warning signs, symptoms and modifiable risk factors. . PMID- 29181229 TI - Lexis Expansion: a prerequisite for analyzing time changing variables in a cohort study. AB - In a prospective analytical cohort study or a study involving a longer follow up, changing age of participants influence the relationship between exposure and outcome. Usually age at entry is incorporated in the regression model to adjust for age. However, this fails to fully explain and adjust for changing age. For this Lexis expansion, a concept by Wilhelm Lexis, allows the analyst to expand the observations as per age bands and check for confounding and interaction by changing age. Lexis expansion assumes the rates to be constant within an age band. PMID- 29181231 TI - Remembering Our Roots. PMID- 29181230 TI - Fungal keratitis: study of increasing trend and common determinants. AB - Fungal keratitis is one of the leading cause of ocular morbidity. Fungal keratitis possesses a clinical challenge due to its slow pathologic process, overlapping features, diagnostic difficulty, and potential complications. Its increasing trend can be attributed to the use of contact lens, non-judiciary corticosteroid, and vegetative trauma. Early diagnosis and treatment is the cornerstone for its effective control. Knowledge of pathological course and clinical characteristics of fungal keratitis will definitely add in early diagnosis and treatment, with reduction in ocular morbidity. This review article explores the risk factor of fungal keratitis, its clinical course and management strategy. PMID- 29181232 TI - Machine Learning to Compare Frequent Medical Problems of African American and Caucasian Diabetic Kidney Patients. AB - Objectives: End-stage renal disease (ESRD), which is primarily a consequence of diabetes mellitus, shows an exemplary health disparity between African American and Caucasian patients in the United States. Because diabetic chronic kidney disease (CKD) patients of these two groups show differences in their medical problems, the markers leading to ESRD are also expected to differ. The purpose of this study was, therefore, to compare their medical complications at various levels of kidney function and to identify markers that can be used to predict ESRD. Methods: The data of type 2 diabetic patients was obtained from the 2012 Cerner database, which totaled 1,038,499 records. The data was then filtered to include only African American and Caucasian outpatients with estimated glomerular filtration rates (eGFR), leaving 4,623 records. A priori machine learning was used to discover frequently appearing medical problems within the filtered data. CKD is defined as abnormalities of kidney structure, present for >3 months. Results: This study found that African Americans have much higher rates of CKD related medical problems than Caucasians for all five stages, and prominent markers leading to ESRD were discovered only for the African American group. These markers are high glucose, high systolic blood pressure (BP), obesity, alcohol/drug use, and low hematocrit. Additionally, the roles of systolic BP and diastolic BP vary depending on the CKD stage. Conclusions: This research discovered frequently appearing medical problems across five stages of CKD and further showed that many of the markers reported in previous studies are more applicable to African American patients than Caucasian patients. PMID- 29181233 TI - Development and Application of Direct Data Capture for Monitoring Medication Compliance in Clinical Trials. AB - Objectives: The monitoring of medication compliance in clinical trials is important but labor intensive. To check medication compliance in clinical trials, a system was developed, and its technical feasibility evaluated. Methods: The system consisted of three parts: a management part (clinical trial center database and a developed program), clinical trial investigator part (monitoring), and clinical trial participant part (personal digital assistant [PDA] with a barcode scanner). The system was tested with 20 participants for 2 weeks, and compliance was evaluated. Results: This study developed a medication compliance monitoring system that used a PDA with a barcode scanner, which sent reminder/warning messages, logged medication barcode data, and provided compliance information to investigators. Registered participants received short message service (SMS) reminder/warning messages on their PDA and sent barcode data at the dosing time. The age range of the participants was 29 to 73 years. Five participants were <50 years old and 8 were >=65 years old. The total mean compliance rate was 82.3%. The mean compliance rate was 83.1% in participants <65 years old and 81.1% in those >=65 years old. Conclusions: The system was feasible, usable, and effective, even with elderly participants, for monitoring medication compliance in clinical trials using a PDA with a barcode scanner, and may improve the quality of clinical trials. PMID- 29181234 TI - Clinical Decision Support Model to Predict Occlusal Force in Bruxism Patients. AB - Objectives: The aim of this study was to develop a decision support model for the prediction of occlusal force from the size and color of articulating paper markings in bruxism patients. Methods: We used the information from the datasets of 30 bruxism patients in which digital measurements of the size and color of articulating paper markings (12-um Hanel; Coltene/Whaledent GmbH, Langenau, Germany) on canine protected hard stabilization splints were measured in pixels (P) and in red (R), green (G), and blue (B) values using Adobe Photoshop software (Adobe Systems, San Jose, CA, USA). The occlusal force (F) was measured using T Scan III (Tekscan Inc., South Boston, MA, USA). The multiple regression equation was applied to predict F from the P and RGB. Model evaluation was performed using the datasets from 10 new patients. The patient's occlusal force measured by T Scan III was used as a 'gold standard' to compare with the occlusal force predicted by the multiple regression model. Results: The results demonstrate that the correlation between the occlusal force and the pixels and RGB of the articulating paper markings was positive (F = 1.62*P + 0.07*R -0.08*G + 0.08*B + 4.74; R2 = 0.34). There was a high degree of agreement between the occlusal force of the patient measured using T-Scan III and the occlusal force predicted by the model (kappa value = 0.82). Conclusions: The results obtained demonstrate that the multiple regression model can predict the occlusal force using the digital values for the size and color of the articulating paper markings in bruxism patients. PMID- 29181235 TI - Systematic Review of Data Mining Applications in Patient-Centered Mobile-Based Information Systems. AB - Objectives: Smartphones represent a promising technology for patient-centered healthcare. It is claimed that data mining techniques have improved mobile apps to address patients' needs at subgroup and individual levels. This study reviewed the current literature regarding data mining applications in patient-centered mobile-based information systems. Methods: We systematically searched PubMed, Scopus, and Web of Science for original studies reported from 2014 to 2016. After screening 226 records at the title/abstract level, the full texts of 92 relevant papers were retrieved and checked against inclusion criteria. Finally, 30 papers were included in this study and reviewed. Results: Data mining techniques have been reported in development of mobile health apps for three main purposes: data analysis for follow-up and monitoring, early diagnosis and detection for screening purpose, classification/prediction of outcomes, and risk calculation (n = 27); data collection (n = 3); and provision of recommendations (n = 2). The most accurate and frequently applied data mining method was support vector machine; however, decision tree has shown superior performance to enhance mobile apps applied for patients' self-management. Conclusions: Embedded data-mining based feature in mobile apps, such as case detection, prediction/classification, risk estimation, or collection of patient data, particularly during self management, would save, apply, and analyze patient data during and after care. More intelligent methods, such as artificial neural networks, fuzzy logic, and genetic algorithms, and even the hybrid methods may result in more patients centered recommendations, providing education, guidance, alerts, and awareness of personalized output. PMID- 29181236 TI - Machine Learning to Improve the Effectiveness of ANRS in Predicting HIV Drug Resistance. AB - Objectives: Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is one of the major burdens of disease in developing countries, and the standard-of-care treatment includes prescribing antiretroviral drugs. However, antiretroviral drug resistance is inevitable due to selective pressure associated with the high mutation rate of HIV. Determining antiretroviral resistance can be done by phenotypic laboratory tests or by computer-based interpretation algorithms. Computer-based algorithms have been shown to have many advantages over laboratory tests. The ANRS (Agence Nationale de Recherches sur le SIDA) is regarded as a gold standard in interpreting HIV drug resistance using mutations in genomes. The aim of this study was to improve the prediction of the ANRS gold standard in predicting HIV drug resistance. Methods: A genome sequence and HIV drug resistance measures were obtained from the Stanford HIV database (http://hivdb.stanford.edu/). Feature selection was used to determine the most important mutations associated with resistance prediction. These mutations were added to the ANRS rules, and the difference in the prediction ability was measured. Results: This study uncovered important mutations that were not associated with the original ANRS rules. On average, the ANRS algorithm was improved by 79% +/- 6.6%. The positive predictive value improved by 28%, and the negative predicative value improved by 10%. Conclusions: The study shows that there is a significant improvement in the prediction ability of ANRS gold standard. PMID- 29181237 TI - Prediction of Kidney Graft Rejection Using Artificial Neural Network. AB - Objectives: Kidney transplantation is the best renal replacement therapy for patients with end-stage renal disease. Several studies have attempted to identify predisposing factors of graft rejection; however, the results have been inconsistent. We aimed to identify prognostic factors associated with kidney transplant rejection using the artificial neural network (ANN) approach and to compare the results with those obtained by logistic regression (LR). Methods: The study used information regarding 378 patients who had undergone kidney transplantation from a retrospective study conducted in Hamadan, Western Iran, from 1994 to 2011. ANN was used to identify potential important risk factors for chronic nonreversible graft rejection. Results: Recipients' age, creatinine level, cold ischemic time, and hemoglobin level at discharge were identified as the most important prognostic factors by ANN. The ANN model showed higher total accuracy (0.75 vs. 0.55 for LR), and the area under the ROC curve (0.88 vs. 0.75 for LR) was better than that obtained with LR. Conclusions: The results of this study indicate that the ANN model outperformed LR in the prediction of kidney transplantation failure. Therefore, this approach is a promising classifier for predicting graft failure to improve patients' survival and quality of life, and it should be further investigated for the prediction of other clinical outcomes. PMID- 29181238 TI - Development of a Stress Classification Model Using Deep Belief Networks for Stress Monitoring. AB - Objectives: Stress management is related to public healthcare and quality of life; an accurate stress classification method is necessary for the design of stress monitoring systems. Therefore, the goal of this study was to design a novel stress classification model using a deep learning method. Methods: In this paper, we present a stress classification model using the dataset from the sixth Korea National Health and Nutrition Examination Survey conducted from 2013 to 2015 (KNHANES VI) to analyze stress-related health data. Statistical analysis was performed to identify the nine features of stress detection, and we evaluated the performance of the proposed stress classification by comparison with several stress detection models. The proposed model was also evaluated using Deep Belief Networks (DBN). Results: We designed profiles depending on the number of hidden layers, nodes, and hyper-parameters according to the loss function results. The experimental results showed that the proposed model achieved an accuracy and a specificity of 66.23% and 75.32%, respectively. The proposed DBN model performed better than other classification models, such as support vector machine, naive Bayesian classifier, and random forest. Conclusions: The proposed model in this study was demonstrated to be effective in classifying stress detection, and in particular, it is expected to be applicable for stress prediction in stress monitoring systems. PMID- 29181239 TI - Validity of Principal Diagnoses in Discharge Summaries and ICD-10 Coding Assessments Based on National Health Data of Thailand. AB - Objectives: This study examined the validity of the principal diagnoses on discharge summaries and coding assessments. Methods: Data were collected from the National Health Security Office (NHSO) of Thailand in 2015. In total, 118,971 medical records were audited. The sample was drawn from government hospitals and private hospitals covered by the Universal Coverage Scheme in Thailand. Hospitals and cases were selected using NHSO criteria. The validity of the principal diagnoses listed in the "Summary and Coding Assessment" forms was established by comparing data from the discharge summaries with data obtained from medical record reviews, and additionally, by comparing data from the coding assessments with data in the computerized ICD (the data base used for reimbursement purposes). Results: The summary assessments had low sensitivities (7.3%-37.9%), high specificities (97.2%-99.8%), low positive predictive values (9.2%-60.7%), and high negative predictive values (95.9%-99.3%). The coding assessments had low sensitivities (31.1%-69.4%), high specificities (99.0%-99.9%), moderate positive predictive values (43.8%-89.0%), and high negative predictive values (97.3% 99.5%). The discharge summaries and codings often contained mistakes, particularly the categories "Endocrine, nutritional, and metabolic diseases", "Symptoms, signs, and abnormal clinical and laboratory findings not elsewhere classified", "Factors influencing health status and contact with health services", and "Injury, poisoning, and certain other consequences of external causes". Conclusions: The validity of the principal diagnoses on the summary and coding assessment forms was found to be low. The training of physicians and coders must be strengthened to improve the validity of discharge summaries and codings. PMID- 29181240 TI - Satisfaction with Paper-Based Dental Records and Perception of Electronic Dental Records among Dental Professionals in Myanmar. AB - Objectives: To overcome challenges in the implementation of electronic dental record systems in a low-resource setting, it is crucial to know the level of users' satisfaction with the existing system of paper-based dental records and their perceptions of electronic dental records. Methods: A cross-sectional paper based questionnaire survey was conducted among Myanmar dental professionals who worked in one of two teaching hospitals or in private dental clinics. Descriptive data were analyzed and regression analysis was carried out to identify factors influencing perceptions of electronic dental records. Results: Most dental professionals (>60%) were satisfied with just three out of six aspects of paper based dental records (familiarity, flexibility, and portability). In addition, generalized positive perceptions were found among decision makers towards electronic dental records, and 86% of dentists indicated that they were willing to use them. Financial concerns were identified as the most important barrier to the implementation of electronic dental records among dentists who were not willing to use the proposed system. Conclusions: The first step towards implementing electronic dental records in Myanmar should be improvement of the content and structure of paper-based dental records, especially in private dental clinics. Utilization of appropriate open-source electronic dental record software in private dental clinics is recommended to address perceived issues around financial barriers. For the long term, we recommend providing further education and training in health informatics to healthcare professionals to facilitate the efficient use of electronic dental record software in Myanmar in the future. PMID- 29181241 TI - Technology and Policy Challenges in the Adoption and Operation of Health Information Exchange Systems. AB - Objectives: This study aimed to identify problems and issues that arise with the implementation of online health information exchange (HIE) systems in a medical environment and to identify solutions to facilitate the successful operation of future HIE systems in primary care clinics and hospitals. Methods: In this study, the issues that arose during the establishment and operation of an HIE system in a hospital were identified so that they could be addressed to enable the successful establishment and operation of a standard-based HIE system. After the issues were identified, they were reviewed and categorized by a group of experts that included medical information system experts, doctors, medical information standard experts, and HIE researchers. Then, solutions for the identified problems were derived based on the system development, operation, and improvement carried out during this work. Results: Twenty-one issues were identified during the implementation and operation of an online HIE system. These issues were then divided into four categories: system architecture and standards, documents and data items, consent of HIE, and usability. We offer technical and policy recommendations for various stakeholders based on the experiences of operating and improving the online HIE system in the medical field. Conclusions: The issues and solutions identified in this study regarding the implementation and operate of an online HIE system can provide valuable insight for planners to enable them to successfully design and operate such systems at a national level in the future. In addition, policy support from governments is needed. PMID- 29181242 TI - Association between Health Information Technology and Case Mix Index. AB - Objectives: Health information technology (IT) can assist healthcare providers in ordering medication and adhering to guidelines while improving communication among providers and the quality of care. However, the relationship between health IT and Case Mix Index (CMI) has not been thoroughly investigated; therefore, this study aimed to clarify this relationship. Methods: To examine the effect of health IT on CMI, a generalized estimation equation (GEE) was applied to two years of California hospital data. Results: We found that IT was positively associated with CMI, indicating that increased IT adoption could lead to a higher CMI or billing though DRG up-coding. This implies that hospitals' revenue could increase around $40,000 by increasing IT investment by 10%. Conclusions: The positive association between IT and CMI implies that IT adoption itself could lead to higher patient billings. Generally, a higher CMI in a hospital indicates that the hospital provides expensive services with higher coding and therefore receives more money from patients. Therefore, measures to prevent upcoding through IT systems should be implemented. PMID- 29181243 TI - Development and Cross-cultural Validation of the Korean Version of SMArtphone's uSability Heuristics (SMASH). AB - Objectives: The purpose of this study was to develop and cross-culturally validate the Korean version of SMArtphone's uSability Heuristics (K-SMASH). Methods: In the study, it was used the adaptation process consisted of five stages, namely, translation, synthesis, back translation, expert committee review, and pretesting. In the pretesting stage, a mobile application, using the prefinal K-SMASH, was evaluated for the severity of usability problems by three experts in computer science and informatics. Each participant completed the evaluation and was interviewed about their understanding, interpretation, and opinion of the cultural relevance of the prefinal K-SMASH. Next, we reviewed the differences in the experts' opinions and the questionnaire results. Results: Twelve SMASH items, words and sentences, were translated, back translated, and revised, considering the conceptual meaning in the context of the Korean culture, by experts in various fields, including a Korean linguist and a bilingual translator, through the first stage to the fourth stage. In the pretesting stage, the results showed no major differences among the severity ratings of participants. Furthermore, all participants answered that there were no critical discrepancies or inconsistencies with the cultural relevance of the prefinal K SMASH. Conclusions: The results of the study provide preliminary evidence that the modified K-SMASH can be used for heuristic evaluation, one of the usability tests, when developing applications in Korea. PMID- 29181244 TI - System for Collecting Biosignal Data from Multiple Patient Monitoring Systems. AB - Objectives: Biosignal data include important physiological information. For that reason, many devices and systems have been developed, but there has not been enough consideration of how to collect and integrate raw data from multiple systems. To overcome this limitation, we have developed a system for collecting and integrating biosignal data from two patient monitoring systems. Methods: We developed an interface to extract biosignal data from Nihon Kohden and Philips monitoring systems. The Nihon Kohden system has a central server for the temporary storage of raw waveform data, which can be requested using the HL7 protocol. However, the Philips system used in our hospital cannot save raw waveform data. Therefore, our system was connected to monitoring devices using the RS232 protocol. After collection, the data were transformed and stored in a unified format. Results: From September 2016 to August 2017, we collected approximately 117 patient-years of waveform data from 1,268 patients in 79 beds of five intensive care units. Because the two systems use the same data storage format, the application software could be run without compatibility issues. Conclusions: Our system collects biosignal data from different systems in a unified format. The data collected by the system can be used to develop algorithms or applications without the need to consider the source of the data. PMID- 29181245 TI - Usages of Computers and Smartphones to Develop Dementia Care Education Program for Asian American Family Caregivers. AB - Objectives: Families of ethnic minority persons with dementia often seek help at later stages of the disease. Little is known about the effectiveness of various methods in supporting ethnic minority dementia patients' caregivers. The objective of the study was to identify smartphone and computer usage among family caregivers of dementia patients (i.e., Korean and Vietnamese Americans) to develop dementia-care education programs for them. Methods: Participants were asked various questions related to their computer or smartphone usage in conjunction with needs-assessment interviews. Flyers were distributed at two ethnic minority community centers in Southern California. Snowball recruitment was also utilized to reach out to the families of dementia patients dwelling in the community. Results: Thirty-five family caregivers, including 20 Vietnamese and 15 Korean individuals, participated in this survey. Thirty participants (30 of 35, 85.7%) were computer users. Among those, 76.7% (23 of 30) reported daily usage and 53% (16 of 30) claimed to use social media. A majority of the participants (31 of 35, 88.6%) reported that they owned smartphones. More than half of smartphone users (18 of 29, 62%) claimed to use social media applications. Many participants claimed that they could not attend in-class education due to caregiving and/or transportation issues. Conclusions: Most family caregivers of dementia patients use smartphones more often than computers, and more than half of those caregivers communicate with others through social media apps. A smartphone-app-based caregiver intervention may serve as a more effective approach compared to the conventional in-class method. Multiple modalities for the development of caregiver interventions should be considered. PMID- 29181246 TI - Methods Using Social Media and Search Queries to Predict Infectious Disease Outbreaks. AB - Objectives: For earlier detection of infectious disease outbreaks, a digital syndromic surveillance system based on search queries or social media should be utilized. By using real-time data sources, a digital syndromic surveillance system can overcome the limitation of time-delay in traditional surveillance systems. Here, we introduce an approach to develop such a digital surveillance system. Methods: We first explain how the statistics data of infectious diseases, such as influenza and Middle East Respiratory Syndrome (MERS) in Korea, can be collected for reference data. Then we also explain how search engine queries can be retrieved from Google Trends. Finally, we describe the implementation of the prediction model using lagged correlation, which can be calculated by the statistical packages, i.e., SPSS (Statistical Package for the Social Sciences). Results: Lag correlation analyses demonstrated that search engine data/Twitter have a significant temporal relationship with influenza and MERS data. Therefore, the proposed digital surveillance system can be used to predict infectious disease outbreaks earlier. Conclusions: This prediction method could be the core engine for implementing a (near-) real-time digital surveillance system. A digital surveillance system that uses Internet resources has enormous potential to monitor disease outbreaks in the early phase. PMID- 29181247 TI - Interactive Visualization of Healthcare Data Using Tableau. AB - Objectives: Big data analysis is receiving increasing attention in many industries, including healthcare. Visualization plays an important role not only in intuitively showing the results of data analysis but also in the whole process of collecting, cleaning, analyzing, and sharing data. This paper presents a procedure for the interactive visualization and analysis of healthcare data using Tableau as a business intelligence tool. Methods: Starting with installation of the Tableau Desktop Personal version 10.3, this paper describes the process of understanding and visualizing healthcare data using an example. The example data of colon cancer patients were obtained from health insurance claims in years 2012 and 2013, provided by the Health Insurance Review and Assessment Service. Results: To explore the visualization of healthcare data using Tableau for beginners, this paper describes the creation of a simple view for the average length of stay of colon cancer patients. Since Tableau provides various visualizations and customizations, the level of analysis can be increased with small multiples, view filtering, mark cards, and Tableau charts. Conclusions: Tableau is a software that can help users explore and understand their data by creating interactive visualizations. The software has the advantages that it can be used in conjunction with almost any database, and it is easy to use by dragging and dropping to create an interactive visualization expressing the desired format. PMID- 29181248 TI - EFFECT OF HEEL LIFTS ON PATELLOFEMORAL JOINT STRESS DURING RUNNING. AB - Background: Patellofemoral pain is a debilitating injury for many recreational runners. Excessive patellofemoral joint stress may be the underlying source of pain and interventions often focus on ways to reduce patellofemoral joint stress. Purpose: Heel lifts have been used as an intervention within Achilles tendon rehabilitation programs and to address leg length discrepancies. The purpose of this study was to examine the effect of running with heel lifts on patellofemoral joint stress, patellofemoral stress impulse, quadriceps force, step length, cadence, and other related kinematic and spatiotemporal variables. Study Design: A repeated-measures research design. Methods: Sixteen healthy female runners completed five running trials in a controlled laboratory setting with and without 11mm heel lifts inserted in a standard running shoe. Kinetic and kinematic data were used in combination with a static optimization technique to estimate individual muscle forces. These data were inserted into a patellofemoral joint model which was used to estimate patellofemoral joint stress and other variables during running. Results: When running with heel lifts, peak patellofemoral joint stress and patellofemoral stress impulse were reduced by a 4.2% (p=0.049) and 9.3% (p=0.002). Initial center of pressure was shifted anteriorly 9.1% when running with heel lifts (p<0.001) despite all runners utilizing a heel strike pattern. Dorsiflexion at initial contact was reduced 28% (p=0.016) when heel lifts were donned. No differences in step length and cadence (p>0.05) were shown between conditions. Conclusions: Heel lift use resulted in decreased patellofemoral joint stress and impulse without associated changes in step length or frequency, or other variables shown to influence patellofemoral joint stress. The center of pressure at initial contact was also more anterior using heel lifts. The use of heel lifts may have therapeutic benefits for runners with patellofemoral pain if the primary goal is to reduce patellofemoral joint stress. Level of Evidence: 3b. PMID- 29181249 TI - COMPARISON OF HAMSTRING MUSCLE ACTIVATION DURING HIGH-SPEED RUNNING AND VARIOUS HAMSTRING STRENGTHENING EXERCISES. AB - Purpose/Background: Several studies have examined the effect of hamstring strength exercises upon hamstring strains in team sports that involve many sprints. However, there has been no cross comparison among muscle activation of these hamstring training exercises with actual sprinting. Therefore, the aim of this study was to examine different hamstring exercises and compare the muscle activity in the hamstring muscle group during various exercises with the muscular activity produced during maximal sprints. Methods: Twelve male sports students (age 25 +/- 6.2 years, 1.80 +/- 7.1 m, body mass 81.1 +/- 15.6 kg) participated in this study. Surface EMG electrodes were placed on semimembranosus, semitendinosus and biceps femoris to measure muscle activity during seven hamstrings exercises and sprinting together with 3D motion capture to establish at what hip and knee angles maximal muscle activation (EMG) occurs. Maximal EMG activity during sprints for each muscle was used in order to express each exercise as a percentage of max activation during sprinting. Results: The main findings were that maximal EMG activity of the different hamstring exercises were on average between 40-65% (Semitendinosus), 18-40% (biceps femoris) and 40-75% (Semimembranosus) compared with the max EMG activity in sprints, which were considered as 100%. The laying kick together with the Nordic hamstring exercises and its variations had the highest muscle activations, while the cranes showed the lowest muscle activation (in all muscles) together with the standing kick for the semimembranosus. In addition, angles at which the peak EMG activity of the hamstring muscle occurs were similar for the Nordic hamstring exercises and different for the two crane exercises (hip angle), standing kick (hip angle) and the laying kick (knee angle) compared with the sprint. Conclusions: Nordic hamstring exercises with its variation together with the laying kick activates the hamstrings at high levels and at angles similar to the joint angles at which peak hamstring activation occurs during sprinting, while cranes did not reach high levels of hamstring activation compared with sprinting. Level of Evidence: 1b. PMID- 29181250 TI - THE EFFICACY OF ANGLE-MATCHED ISOKINETIC KNEE FLEXOR AND EXTENSOR STRENGTH PARAMETERS IN PREDICTING AGILITY TEST PERFORMANCE. AB - Background: Agility is a fundamental performance element in many sports, but poses a high risk of injury. Hierarchical modelling has shown that eccentric hamstring strength is the primary determinant of agility performance. Purpose: The purpose of this study was to investigate the relationship between knee flexor and extensor strength parameters and a battery of agility tests. Study Design: Controlled laboratory study. Methods: Nineteen recreational intermittent games players completed an agility battery and isokinetic testing of the eccentric knee flexors (eccH) and concentric knee extensors (conQ) at 60, 180 and 300 degrees .s 1. Peak torque and the angle at which peak torque occurred were calculated for eccH and conQ at each speed. Dynamic control ratios (eccH:conQ) and fast:slow ratios (300:60) were calculated using peak torque values, and again using angle matched data, for eccH and conQ. The agility test battery differentiated linear vs directional changes and prescriptive vs reactive tasks. Results: Linear regression showed that eccH parameters were generally a better predictor of agility performance than conQ parameters. Stepwise regression showed that only angle-matched strength ratios contributed to the prediction of each agility test. Trdaitionally calculated strength ratios using peak torque values failed to predict performance. Angle-matched strength parameters were able to account for 80% of the variation in T-test performance, 70% of deceleration distance, 55% of 10m sprint performance, and 44% of reactive change of direction speed. Conclusions: Traditionally calculated strength ratios failed to predict agility performance, whereas angle-matched strength ratios had better predictive ability and featured in a predictive stepwise model for each agility task. Level of Evidence: 2c. PMID- 29181251 TI - LOWER EXTREMITY KINEMATICS OF ACL-REPAIRED AND NON-INJURED FEMALES WHEN USING KNEE SAVERS(r). AB - Background: Knee Savers(r) (KS) are an ergonomic aid purported to lessen the risk of injuries linked to deep squats. While widely used in sports such as baseball and softball, KS have not been tested to determine their effect upon lower extremity kinematics in any population. Purpose: The purpose of the study was to determine if KS influenced the lower extremity kinematics when females with previous anterior cruciate ligament (ACL)-reconstruction and healthy participants completed an end-range squat. Study Design: A repeated measures, counter-balanced laboratory study design was used. Methods: Twenty female participants (mean (SD) age: 21.65 (2.06) yrs, height: 175.26 (9.29) cm, weight: 64.66 (7.72) kg) with a history of ACL-repair (n=10) or non-injury (n=10) completed this study. Participants completed a standardized trial of three deep squats with and without KS. Movement was analyzed using 2D video analysis methods increasingly available in clinical environments. Results: During the ascending phases of a squatting motion, there was significantly greater medial (p = .009) and lateral (p = .005) motion of the patella in the frontal plane for non-injured participants, when compared to the ACL-repaired group. No significant differences were found in sagittal plane lower extremity kinematics when squatting with and without KS. Ascending angular velocity was slower in ACL-repaired than non-injured females (p = .008) and slower with the KS than without KS for non-injured females (p = .007). Conclusions: When squatting with and without KS, the non-injured group experienced more frontal plane motion at the knee, compared to the ACL-repaired group. However, while KS are purported to influence lower extremity joint positions during the bottom phase of a deep squat, the data from the current study did not support this claim. Additionally, KS appear to slow ascending velocity for those without a history of ACL-repair. These findings may have clinically meaningful implications for athletes who use KS during sport activities. Level of Evidence: Level 2. PMID- 29181252 TI - COMPARISON OF DRY NEEDLING VS. SHAM ON THE PERFORMANCE OF VERTICAL JUMP. AB - Introduction: Dry needling has been reported to decrease pain in subjects having myofascial trigger points, as well as pain in muscle and connective tissue. Objective: The purpose of the study was to compare the effects on the ability to perform a two-legged vertical jump between a group who received one bout of dry needling and a group who received one bout of a sham treatment. Methods: Thirty five healthy students (19 males, 16 females) were recruited to participate in this study (mean age 22.7+/- 2.4 years). The subjects were randomly divided into two groups- dry needling (n=18) vs sham (n=17). The dry needling group received needling to four sites on bilateral gastrocnemius muscles; two at the medial head and two at the lateral head. The sham group had the four areas of the gastrocnemius muscle pressed with the tube housing the needle, but the needle was never inserted into the skin. Two-legged vertical jump was measured with chalk marks on the wall before and after the dry needling and sham treatments. Results: Analysis with a t-test indicated that the dry needling group significantly increased vertical jump height 1.2 inches over the sham group. Conclusion: One bout of dry needling showed an immediate effect at significantly increasing vertical jump height in healthy, young adults. Future research is needed to determine if dry needling has any long-term effects. Level of Evidence: 2b. PMID- 29181253 TI - INTER-RATER RELIABILITY OF THE SELECTIVE FUNCTIONAL MOVEMENT ASSESSMENT (SFMA) BY SFMA CERTIFIED PHYSICAL THERAPISTS WITH SIMILAR CLINICAL AND RATING EXPERIENCE. AB - Background: The Selective Functional Movement Assessment (SFMA) assesses posture, muscle balance, and movement patterns in order to identify relevant musculoskeletal dysfunction in a clinical population. Purpose: The purposes of this study were to: (1) determine if raters with similar clinical experience and rating experience exhibit adequate agreement of the scoring for the SFMA during clinical use; (2) determine the reliability of the categorical scoring of the SFMA in a clinical population; (3) determine the reliability of the criterion checklist scoring of the SFMA in a clinical population; (4) compare the reliability of real-time assessment to recorded assessment. Design: Inter-rater reliability study. Methods: 49 clinical subjects (20.7 years +/- 1.6) were simultaneously assessed in real-time by two physical therapists and were recorded with digital video cameras in the sagittal and frontal view while they performed the fifteen component movement patterns that comprise the top-tier SFMA. The third physical therapist assessed the patterns from the video. Subjects were assessed using the SFMA categorical scoring and criterion checklist scoring tools. Results: The two live clinical raters demonstrated the greatest Cohen's Kappa scores (10 of 15) with moderate or better inter-rater agreement (Kappa > 0.40) using the categorical scoring tool. The overall ICC [2,1] score indicated fair to moderate agreement between all raters for the criterion checklist scoring (ICC, SEM, p-value) (0.61, 8.23, p < 0.001). Real time clinical use was the most reliable method for using the criterion checklist scoring tool (0.72, 1.95, p=0.43). Conclusions: Using the categorical and criterion checklist tools in a clinical population to score the fifteen component fundamental movements of the SFMA demonstrated moderate or better reliability when performed clinically by certified SFMA raters. Level of Evidence: Reliability, Level 2. PMID- 29181254 TI - HIP RANGE OF MOTION IN RECREATIONAL WEIGHT TRAINING PARTICIPANTS: A DESCRIPTIVE REPORT. AB - Background: The surveillance of hip injuries and risk factors have become an emerging focus in sports medicine due to the increased recognition of hip pathologies. Researchers suggest that decreased hip range of motion (ROM) is a risk factor for injury in various athletic activities. One under reported population that has potential for hip injuries is recreational weight training (WT) participants. Currently, no studies have reported hip ROM values in WT participants which creates a knowledge gap in this population. Purpose: The purpose of this study was to report hip passive ROM values of WT participants to develop reference data for future research on injury patterns and prevention strategies for this population. Study Design: Descriptive cross sectional study. Methods: Two-hundred healthy recreational adult WT participants (age = 27.18 +/- 9.3 years, height = 174.84 +/- 9.8 cm, mass = 91.0 +/- 17.9 kg, body mass index = 29.6 +/- 4.5 kg/m2) were recruited. Bilateral hip passive ROM was assessed for flexion, extension, internal rotation, external rotation, and abduction. Statistical analysis included subject demographics (means and SD) and a two tailed independent t-test to compare mean passive hip ROM values between sexes and hips. Statistical significance was considered p < .05. Results: A total of 400 hundred hips (right + left) were measured for this analysis. When comparing hip ROM values within sexes, men had no significant difference (p>=.28) between the right and left hip for all motions. Women did have a significant difference (p<=.05) between the right and left hip for all motions. The right hip had lower values for all motions than the left hip suggesting a more global decrease in right hip ROM. When comparing hip ROM values between men and women, there was a significant difference (p<=.05) between men and women for all motions. Men had lower ROM values for all hip motions when compared to women. Conclusion: This is the first investigation to provide a descriptive analysis of hip ROM in healthy recreational WT participants. These data provide a starting point for clinicians and researchers to further study this population for injury prevention. Evidence Level: 2. PMID- 29181256 TI - SPORTS PHYSICAL THERAPY CURRICULA IN PHYSICAL THERAPIST PROFESSIONAL DEGREE PROGRAMS. AB - Background: The specialty niche of sports physical therapy has grown at a significant rate over the past 40 years. Despite this growth there is little information or direction from the physical therapy education accreditation body or professional association to guide academic programs on the interest or necessity of this type of practice content in physical therapy professional degree programs. Purpose: The purpose of this survey study is to report on the prevalence, attitudes, barriers, resources, and faculty expertise in providing required or elective sports physical therapy course work. Study Design: Cross sectional descriptive survey. Methods: A 57-item questionnaire with branching logic was distributed via a web-based electronic data capture tool to survey all Commission on Accreditation for Physical Therapy Education (CAPTE) accredited and candidate schools in the United States. Response data was analyzed to describe typical educational program profiles, faculty demographics, and correlational factors consistent with the presence or absence of specific sports physical therapy curricular content. Results: Thirty one percent of the schools responded to the survey and the program demographics were consistent with all currently accredited schools in regards to their geography, Carnegie classification, and faculty and student size. Forty three percent of programs offered a required or elective course distinct to the practice of sports physical therapy. Descriptive information regarding the sequencing, curricular make-up, resources, and assessment of content competence is reported. The odds of providing this content nearly doubles for programs that have faculty with sports clinical specialist credentials, accredited sports residency curriculums, or state practice acts that allow sports venue coverage. Conclusions: This survey provides an initial overview of sports physical therapy educational efforts in professional physical therapy degree programs. The data can used to spur further discussion on the necessity, structure, and implementation of education content that is inherent to a growing specialty practice in the physical therapy profession.

AB - Introduction: Dysfunctional breathing (DB) has been linked to health conditions including low back pain and neck pain and adversely effects the musculoskeletal system. Individuals with DB often have decreased pain thresholds and impaired motor control, balance, and movement. No single test or screen identifies DB, which is multi-dimensional, and includes biochemical, biomechanical, and psychophysiological components. Several tools assess and test for DB, but no screen exists to determine whether additional testing and assessment are indicated. Purpose/Background: The purpose of this study was to develop a breathing screening procedure that could be utilized by fitness and healthcare providers to screen for the presence of disordered breathing. A diagnostic test study approach was utilized to establish the diagnostic accuracy of the newly developed screen for DB. Methods: A convenience sample of 51 subjects (27 females, 27.0 years, BMI 23.3) were included. To test for DB related to the biochemical dimension, end-tidal CO2 (ETCO2) was measured with a capnography unit. To test for DB related to biomechanical dimension, the Hi-Lo test was utilized. To test for DB related to the psychophysiological dimension, the Self Evaluation of Breathing Symptoms Questionnaire (SEBQ) and Nijmegen questionnaires were utilized. Potential screening items that have been shown to be related to DB in previous research and that could be performed by non-health care personnel were utilized to create the index test including activity level, breath hold time (BHT), respiration rate, and the Functional Movement Screen (FMSTM). Results: There were no strong correlations between the three measures of DB. Five subjects had normal breathing, 14 failed at least one measure, 20 failed at least two, and 12 failed all three. To develop screening items for each dimension, data were examined for association with failure. BHT and a four-item mini-questionnaire were identified as the most closely associated variables with failure of all three dimensions. A BHT of < 25 seconds and four questions were combined and yielded a sensitivity of 0.89 (0.85-0.93) and a specificity of 0.60 (0.18-0.92) for clinical identification of DB. Conclusion: Easily obtained clinical measures of BHT and four questions can be utilized to screen for the presence of DB. If the screen is passed, there is an 89% chance that DB is not present. If the screen is failed, further assessment is recommended. Level of Evidence: 2b. PMID- 29181257 TI - SHOULDER PAIN IN COMPETITIVE TEENAGE SWIMMERS AND IT'S PREVENTION: A RETROSPECTIVE EPIDEMIOLOGICAL CROSS SECTIONAL STUDY OF PREVALENCE. AB - Background: The term "swimmer's shoulder" was first introduced in 1974 by Kennedy and Hawkins to describe a common condition among competitive swimmers characterized by pain and dysfunction of the shoulder complex. Currently, the term does not define a specific clinical diagnosis and its etiology is considered to be multifactorial. In the literature shoulder pain prevalence varies according to the adopted definitions (from 3% to 91%); however, in the Italian environment there is no prevalence study regarding swimmer shoulder. Prevention by means of dry land activities may assist in delimiting shoulder pain in swimmers. Purposes: The purpose of this study was to investigate the prevalence of swimmer's shoulder over the prior 12 months among teenage athletes and the preventive activities carried out across different sport's teams. A second purpose was to determine whether the extent of the condition is affected by dry land preventive activity. And finally, to compare different preventive activities related to the prevalence of swimmer's shoulder. Study design: Retrospective epidemiological cross sectional study of prevalence. Methods: Athletes from four levels of training: Esordienti A, Ragazzi, Juniores and Cadetti (according to Italian Swimming Federation F.I.N.'s partition age) belonging to eight Italian swimming teams and their respective coaches were involved in this study. Two types of questionnaires were created and completed by both the athletes and their coaches during May 2015. The collected data were analyzed by means of descriptive and inferential statistics. Results: Shoulder pain prevalence over the previous 12 months from the completion of the survey was 51%. In six out of eight of the societies a specific shoulder dry land warm-up was carried out before water training, whereas among seven out of eight societies also utilized weekly sessions of performance (physical) training. Statistically significant differences were noticed between shoulder pain and gender, weekly frequency and duration of dry land warm-up and duration of physical training. Conclusion: The results of the current study indicate that shoulder pain is prevalent in youth swimmers (51%) and appears to be affected by dry land preventive activities. A weekly frequency of dry land warm-up more than five times appeared to protect swimmers from pain (p=0.044); whereas, a dry land warm-up duration greater than 10 minutes seems to cause shoulder pain (p=0.043). A single physical training duration lower than 45 minutes seems to be associated with pain (p=0.035). Levels of evidence: 3a.

AB - Background: There is a lack of information about the influence of age on functional movement tests (FMT) and performance tests as well as in their relationships in young basketball players. Purpose: The purpose of the present study was to determine the variations in FMT and jump and/or sprint performance scores between age groups (U-14 vs. U-16) in Highly-trained young basketball players. The second purpose was to investigate the relationship between FMT for lower body and jump and/or sprint performance in highly-trained young (U-14 and U 16) male basketball players. Study Design: Descriptive study. Methods: Thirty elite young (U-14 to U-16) male basketball players performed several FMT (weight bearing dorsiflexion test [WB-DF] and a modified Star Excursion Balance test [SEBT]) and performance including unilateral and bilateral countermovement jumps, unilateral horizontal jumping, linear sprinting and performance tests. Results: All anthropometric and performance tests showed a statistically significant advantage (p<0.05) in the U-16 group, excluding the unilateral jump with left leg (p=0.127). Five out of the eight FMT performed showed a statistically significant advantage (p<0.05) in the U-16 group. The U-14 group did not differ statistically from the U-16 group in WB-DF with left leg and the SEBT anterior right leg and posteromedial left leg reaches. Effect size calculations did show small to moderate effects in favor of U-16. Only two significant correlations (p<0.05) between functional movement and performance measures were identified in the U-16 group for either limb (10-m sprint and SEBT-PLL, SEBT-CompositeL), while a total of 13 significant correlations (p<0.05) in the U-14 group were found. Conclusions: The results of this study demonstrated differences in FMT and jump and/or sprint performance test between age groups (U-16 vs U-14). The findings of this study support the idea that the age of the player should be considered when interpreting FMT scores, which could have implications when implementing the FMT for injury risk prediction.

AB - Background: Prospective injury registration studies, monitoring adolescent elite athletes, are sparse in running, orienteering and cross-country skiing, yet essential for developing prevention programs. Purpose: The aims of this study were to describe the injury prevalence/incidence, severity grade, injury location, risk factors and the prevalence of illness in running (RU), orienteering (OR) and cross-country skiing athletes (CR). Study Design: Prospective cohort study. Methods: One hundred fifty adolescent elite athletes (age range 16-19), participating in orienteering (25 females, 20 males), running (13 females, 18 males), cross-country skiing (38 females, 36 males), from 12 National Sports High Schools in Sweden, were prospectively followed over one calendar year using a reliable and validated web-based questionnaire. Results: The main finding was that the average weekly injury prevalence was higher during the pre-season compared to the competitive season in all three sports. RU reported the significantly (p<0.05) highest average weekly injury prevalence (32.4%) and substantial injury prevalence (17.0%), compared to OR (26.0, 8.2%) and CR (21.1%, 8.9%). Most injuries occurred in the lower extremity (RU 94.4%; OR 91.9%; CR 49.9%) and foot and knee injuries had the highest severity grade in all three sports. History of serious injury (p=0.002, OR 4.0, 95% CI 1.6-9.7) and current injury at study start (p=0.004, OR 4.0, 95% CI 1.5-11.2) were identified as the strongest risk factors for substantial injury. Younger athletes aged 16 (p=0.019, OR 2.6, 95% CI 1.2-5.8) and 17 (p=0.045, OR 2.4, 95% CI 1.0-5.9), had a significantly higher injury risk for substantial injury compared to older athletes aged 18-19. Conclusion: Practitioners should be aware of the increased injury risk during pre-season and in younger athletes. By focus on prevention of foot and knee injuries, the injuries with the highest severity grade will be targeted in adolescent elite athletes participating in running, orienteering and cross-country skiing.

AB - Background: Quidditch is a fast growing, physically intense, mixed-gender full contact sport. Originally adapted from Harry Potter novels, quidditch was first played in 2005 in the USA but is now played worldwide. It is essential to elucidate patterns of injury for the safety and growth of the sport of quidditch. It also provides a unique opportunity to study injury patterns in mixed-gender full-contact sport, an area of increasing importance with the developing culture of transition from single-gender to mixed-gender sports. Purpose: The purpose of this investigation was to examine the types of injuries sustained while playing quidditch in terms of their incidence, anatomical distribution and severity, and gender distribution. Methods: An anonymous self-reporting questionnaire was distributed to all active quidditch players in the UK. Data collection included player demographics, type of injury, mechanism of injury, player position, experience and treatment required, relating to the previous 12 months. Results: A total of 348 participants of 684 eligible athletes responded to the questionnaire representing a 50.87% response rate. There were 315 injuries reported by 180 athletes in total, with an overall incidence of 4.06 injuries per 1,000 hours. A statistically significantly different rate of concussion was observed with female athletes sustaining more concussion than males (p=0.006). The overall rate of concussion was 0.651/1000hrs in males and 1.163/1000hrs in females (0.877/1000 hours overall). Conclusions: This study provides the first quantitative description of injury rates in quidditch. The overall injury rates are no higher than those reported in other recreational contact sports. Female athletes were found to have a higher rate of concussion, which needs further investigation. These findings are relevant to players concerned about safety in quidditch and to governing bodies regarding governance of the sport. Level of Evidence: 3b. PMID- 29181261 TI - FUNCTIONAL OUTCOMES OF HIP ARTHROSCOPY IN AN ACTIVE DUTY MILITARY POPULATION UTILIZING A CRITERION-BASED EARLY WEIGHT BEARING PROGRESSION. AB - Introduction: Hip arthroscopy allows surgeons to address intra-articular pathology of the hip while avoiding more invasive open surgical dislocation. However the post-operative rehabilitation protocols have varied greatly in the literature, with many having prolonged periods of limited motion and weight bearing. Purpose: The purpose of this study was to describe a criterion-based early weight bearing protocol following hip arthroscopy and investigate functional outcomes in the subjects who were active duty military. Methods: Active duty personnel undergoing hip arthroscopy for symptomatic femoroacetabular impingement were prospectively assessed in a controlled environment for the ability to incorporate early postoperative weight-bearing with the following criteria: no increased pain complaint with weight bearing and normalized gait pattern. Modified Harris Hip (HHS) and Hip Outcome score (HOS) were performed preoperatively and at six months post-op. Participants were progressed with a standard hip arthroscopy protocol. Hip flexion was limited to not exceed 90 degrees for the first three weeks post-op, with progression back to running beginning at three months. Final discharge was dependent upon the ability to run two miles at military specified pace and do a single leg broad jump within six inches of the contralateral leg without an increase in pain. Results: Eleven participants met inclusion criteria over the study period. Crutch use was discontinued at an average of five days following surgery based on established weight bearing criteria. Only one participant required continued crutch use at 15 days. Participants' functional outcome was improved postoperatively, as demonstrated by significant increases in HOS and HHS. At the six month follow up, eight of 11 participants were able to take and complete a full Army Physical Fitness Test. Conclusions: Following completion of the early weight bearing rehabilitation protocol, 81% of participants were able to progress to full weight bearing by four days post-operative, with normalized pain-free gait patterns. Active duty personnel utilizing an early weight bearing protocol following hip arthroscopy demonstrated significant functional improvement at six months. Level of Evidence: Level 4, Case-series. PMID- 29181262 TI - EXERCISE, MANUAL THERAPY AND POSTURAL RE-EDUCATION FOR UNCONTROLLED EAR TWITCHING AND RELATED IMPAIRMENTS AFTER WHIPLASH INJURY: A CASE REPORT. AB - Background and Purpose: Whiplash Associated Disorders and the interventions used to remediate them are well documented in physical therapy literature. However, specific interventions for spasms of the neck musculature that also involve constant ear twitching have yet to be addressed. The purpose of this case report is twofold. First, to describe comprehensive physical therapy management and outcomes for a subject with uncontrolled ear twitching and related musculoskeletal impairments, and second, to discuss the physical therapist's approach to evidence-based care when faced with a paucity of literature addressing physical therapy interventions for subjects with uncontrolled ear twitching. Case Description: The subject was a 14-year-old female who sustained a right anterolateral whiplash injury when struck in the head by a volleyball seven months prior to physical therapy. Beginning five months after that injury, she experienced uncontrolled and constant superior/inferior movement of her right ear (hereafter described in this report as a twitch) in addition to facial and cervical pain from her initial injury. She was unable to participate in high school athletics due to her pain. A multimodal treatment approach including exercise, manual therapy, and postural reeducation was utilized during the subject's episode of care. Outcomes: After eight treatment sessions, the subjects's cervical range of motion and upper extremity strength improved. The reported frequency of ear twitching decreased, as did reports of neck and shoulder pain. In addition, her Neck Disability Index improved from a score of 22, indicating moderate disability, to 9, indicating mild disability and she was able to return to sport activity. Discussion: With limited research to direct intervention, clinical reasoning was utilized to formulate an effective therapeutic intervention. A combination of manual therapy, exercise, and postural reeducation intervention was effective for this subject and could assist in guiding interventions for similarly unique clinical presentations in the future. Further research is needed to examine the etiology of ear twitching caused by muscle spasm and to develop additional evidence-based interventions for Whiplash Associated Disorders.

AB - Depending on contemporary treatment approach of aggressive immunosuppression, Aplastic Anemia (AA) is caused by immunological destruction of otherwise normal hematopoietic stem cells. The aim was to summarize the cytogenetic abnormalities in AA patients and the frequency of Fanconi Anemia (FA) in morphologically normal AA patients in eastern India. Ethical clearances were obtained from both institutions involved in this study. Out of 72800 patients attending the outpatient department, 520 pancytopenia patients were screened for AA after Bone marrow (BM) aspiration and biopsy. Samples were collected from 117 cases in 3 phases. 51 peripheral venous blood (PVB) samples in the first phase, 19 BM & PVB paired samples in the second phase and 47 BM samples in third phase were collected followed by leukocyte and/or BM stem cell culture. Next GTG banding and karyotyping were performed. PVB was collected from 63 (< 50 years) AA patients and stress cytogenetics was done to diagnose FA. In the first phase of the study, out of 51 PVB samples, 1 (1.96%) showed a unique chromosomal abnormality, i.e. 45,XY,rob(14:21)(p10:q10)[20]. In the second phase of study, among 19 BM & PVB paired samples, 1 (5.26%) showed abnormal karyotype i.e. 45,X,-Y[3]/46,XY[47]. In the third phase of the study, 47 BM samples showed normal karyotype. Only 6 (9.52%) cases were found positive for stress cytogenetics. A negligible percentage showing cytogenetic abnormality in such a considerable number of AA cases indicates that routine cytogenetic analysis of AA patient is not essential. A significant percentage was positive for stress cytogenetics; suggestive for FA, even the patients were morphologically normal. PMID- 29181265 TI - Off label use of direct oral anticoagulants for left ventricular thrombus. Is it appropriate? AB - A 57 year old gentleman with a history of non-ischemic cardiomyopathy and paroxysmal atrial fibrillation presented with worsening lower extremity edema and dyspnea on exertion. He had been compliant with his medications including rivaroxaban (Xarelto) for atrial fibrillation that he takes with the evening meal daily. His echocardiogram showed an ejection fraction of 10-15% and a new left ventricle (LV) apical thrombus. During his hospital stay, he developed right sided weakness. Magnetic Resonance Imaging showed a subacute infarct involving the left parietal lobe. The decision was made to discontinue rivaroxaban and initiate heparin infusion instead. Meanwhile, the patient's neurological symptoms were closely monitored. The patient was then transitioned to warfarin. He was eventually transferred to the rehabilitation floor with minimal residual neurologic weakness. Left ventricular thrombus is an important complication in the setting of systolic dysfunction. The combination of blood stasis, endothelial injury and hypercoagulability, is a prerequisite for in-vivo thrombus formation. The slow onset of action and reversal, need for frequent monitoring, narrow therapeutic range, dietary restrictions, and multiple drug interactions limit the use of vitamin K antagonists. Direct-acting oral anticoagulants (DOACs) do not have these limitations and may also reduce the risk of hemorrhagic stroke. Our patient developed an LV thrombus while on uninterrupted DOAC therapy. PMID- 29181264 TI - Evaluation of bone mineral density and related parameters in patients with haemophilia: a single center cross-sectional study. AB - Haemophilia has been associated with low bone mineral density (BMD) probably due to some predisposing factors. The aim of this study was to evaluate the relationship between BMD and potential clinical predictors in adult haemophilic patients. Fortynine patients with moderate and severe haemophilia were enrolled. BMD was measured by Dual Energy X-Ray Absorptiometry (DXA) and blood tests were performed for vitamin D, calcium, phosphore, alkaline phosphatase and parathormone levels. Functional Independence Score in Haemophilia (FISH) and Haemophilia Joint Health Score (HJHS) were used to assess musculoskeletal functions. Body mass index (BMI), Hepatitis C virus (HCV)/Human immunodeficiency virus (HIV) seropositivity and smoking status were also recorded. BMD was found lower than expected for reference age in 34.8% of patients of less than 50 years old. In patients older than 50 years, 66.6% of them had osteoporosis and 33.3% of them had normal BMD. FISH score was statistically significant correlated with BMD of total hip (TH) and femur neck (FN) but not with lumbar spine (LS). In eligible patients, there was also a statistically significant correlation between BMD of TH and HJHS. Vitamine D deficiency was common and found in 77.5% of patients, although there was no significant correlation with BMD. Also no correlation was found between BMD and blood tests, HCV/HIV status, BMI and smoking. This study confirmed that patients with haemophilia have an increased prevelance of low BMD even in younger group. Our results showed that there are significant correlations between FISH score and BMD of TH and FN and also between HJHS score and BMD of TH. Thus, using scoring systems may be beneficial as a simple predictors of BMD to reflect the severity of haemophilic arthropathy. PMID- 29181266 TI - Gender differences in ST-elevation myocardial infarction (STEMI) time delays: experience of a public health service in Salvador-Brazil. AB - BACKGROUND: Delays in attending to ST-elevation myocardial infarction (STEMI) are indicators or markers of quality of health services. Several records suggest gender disparity in cardiac care as a contributor to the increased mortality among women. METHODS: We prospectively enrolled all consecutive STEMI patients who were transferred to our hospital from January through December 2015. The following variables were analyzed: Symptom-to-Door Time (SDT); Time to First ECG (TECG); Transfer Time to Referring Center (TTRC); and Door-to-Cath lab time (DCT). RESULTS: Of the 133 patients, 85 (63.9%) were male and 45 (36%) female. The mean age and body mass index (BMI) between the male and female genders were 56.3 and 60.5 years for the first and 26 and 27.7 Kg/M2 for the second. Diabetes and low school education level were more prevalent in women than men, with statistical significance: 20 (48.8%) vs 18 (26.1%) with P = 0.01 and 26 (54.2%) vs 28 (32.9%) with P = 0.04, respectively. Regarding the times evaluated (SDT, TECG, TTRC and DCT), there was no statistically significant difference in relation to gender. STEMI Killip class I was more prevalent in males: 93 (86.1%) vs 12 (63.2%) cases with P = 0.01, and thrombolysis with a tendency towards the same direction: 17 (20%) vs 4 (8.3%) and P = 0.07. CONCLUSIONS: According to our results women with STEMI had significantly higher prevalence of diabetes and low school education level, as well as a higher proportion of complicated STEMI (Killip class >= II). PMID- 29181267 TI - Variation and repeatability of measured standardized uptake values depending on actual values: a phantom study. AB - Standardized uptake values (SUVs) are the most widely used quantitative imaging biomarkers in positron emission tomography (PET); however, little is known about the changes in variation and repeatability of SUVs depending on the magnitude of the values. We hypothesized that low SUVs have larger variations than high SUVs, and attempted various kinds of experimental PET scans using a phantom. By adjusting the ratio of F-18 solution to tap water, a NEMA IEC body phantom was set for SUVs of 2.0, 4.0, and 8.0 inside six hot spheres. PET data were obtained for 4 hours, and the data reconstructed every 2 min. The SUVmax and SUVpeak of the spheres in all images were recorded. The relative SUVs were calculated by dividing the measured SUV by actual SUV, and used for the Bland-Altman plots. Some variation was observed for the measured SUVs. The measured SUVs for the actual SUV of 2.0 showed the largest variation among those of 2.0, 4.0, and 8.0, and those of 8.0 showed the smallest. Similarly, the relative SUVs showed significantly larger variations for lower values. In addition, the relative SUVmax showed larger variation and value than the relative SUVpeak. The Bland Altman plots showed considerable variation and little agreement, but the degree of variation decreased as the measured value increased. We demonstrated some variation of the measured SUVs, which decreased for larger measured values. Clinicians should consider the inaccuracy of low SUVs not only in daily practice, but also for multi-institutional studies. PMID- 29181268 TI - The flip-flop fungus sign: an FDG PET/CT sign of benignity. AB - Benign granulomatous processes such as fungal infection may mimic metastatic lung cancer on FDG PET/CT. We found that these processes often have draining lymph node(s) with equal or greater FDG activity than associated lung nodule(s), a "flip-flop" of what is commonly seen in lung cancer. The aim of this study was to examine the utility of this "flip-flop fungus" (FFF) sign for diagnosing benign pulmonary disease. FDG PET/CT scans performed between 9/09-3/13 for the indications of pulmonary nodule or mass were reviewed. Scans with at least one hilar or mediastinal FDG avid draining node were included. Patients with a history of cancer, lack of pathologic confirmation, or without at least two years of imaging follow-up were excluded. A total of 209 FDG PET/CT exams were included and reviewed in a blinded fashion. A positive FFF sign had a sensitivity of 60.0% (95% CI: 47.6-71.5%) and specificity of 84.9% (95% CI: 77.8-90.4%) (P<0.0001) for benign disease. With additional strict imaging criteria applied, the FFF sign had a specificity of 98.6% (95% CI: 94.9-99.8%) (P<0.0001) and a positive predictive value of 90.0% (95% CI: 68.3-98.5%). A positive FFF sign was predominately due to granulomatous disease (91%), mostly histoplasmosis (73%). A positive FFF sign combined with positive fungal serology (n=16) had a specificity of 100% for benign disease. The FFF sign predicts benign disease in patients with a lung nodule(s) and an FDG avid draining lymph node(s) that would otherwise be considered worrisome for cancer. PMID- 29181269 TI - Diagnostic test accuracy study of 18F-sodium fluoride PET/CT, 99mTc-labelled diphosphonate SPECT/CT, and planar bone scintigraphy for diagnosis of bone metastases in newly diagnosed, high-risk prostate cancer. AB - The aim of this study was to prospectively compare planar, bone scan (BS) versus SPECT/CT and NaF PET/CT in detecting bone metastases in prostate cancer. Thirty seven consecutive, newly diagnosed, prostate cancer patients with prostate specific antigen (PSA) levels >= 50 ng/mL and who were considered eligible for androgen-deprivation therapy (ADT) were included in this study. BS, SPECT/CT, and NaF PET/CT, were performed prior to treatment and were repeated after six months of ADT. Baseline images from each index test were independently read by two experienced readers. The reference standard was based on a consensus decision made by a multidisciplinary team on the basis of baseline and follow-up images of the index tests, the findings of the baseline index tests by the experienced readers, and any available imaging, biochemical, and clinical data, including the response to ADT. Twenty-seven (73%) of the 37 patients had bone metastases according to the reference standard. The sensitivities for BS, SPECT/CT and NaF PET/CT were 78%, 89%, and 89%, respectively, and the specificities were 90%, 100%, and 90%, respectively. The positive predictive values of BS, SPECT/CT and NaF PET/CT were 96%, 100%, and 96%, respectively, and the negative predictive values were 60%, 77% and 75%, respectively. No statistically significant difference among the three imaging modalities was observed. All three imaging modalities showed high sensitivity and specificity. NaF PET/CT and SPECT/CT showed numerically improved, but not statistically superior, sensitivity compared with BS in this limited and selected patient cohort.

AB - 68Ga-DOTA-tyr3-Octreotide (68Ga-DOTATOC) PET/CT has been shown to have high accuracy in adults with neuroendocrine tumors, however has not been studied in pediatric patients. This study evaluated the safety and accuracy of 68Ga-DOTATOC PET/CT in children and young adults with solid tumors that express somatostatin receptor type 2. A series of three prospective, IRB approved, clinical trials evaluating safety and efficacy of 68Ga-DOTATOC PET/CT were conducted for subjects aged 6 months to 90 years. This study reports the results for the 26 children and young adults, aged 16 months to 29 years who participated in these trials. The administered activity of 68Ga-DOTATOC was 1.59 MBq/kg with an upper limit of 111 MBq for subjects < 18 years and 148 MBq for young adults. Safety was assessed with laboratory studies and patient/parent report of symptoms before and after the scan. Scans were interpreted in consensus by two board-certified nuclear medicine physicians. Each scan was categorized on a patient basis as true positive, true negative, false negative or false positive against a reference standard that included a combination of histopathology, other imaging modalities and clinical follow-up. Nine Grade I adverse events (AEs) occurred among 26 subjects, none of which were attributable to 68Ga-DOTATOC. Sensitivity of 68Ga DOTATOC PET/CT was 88% (14 true positive, 2 false negative) and specificity was 100% (10 true negative, 0 false positive). 68Ga-DOTATOC PET/CT is safe and accurate in children and young adults with solid tumors expressing somatostatin receptor type 2.

AB - Our study evaluates the feasibility of compassionate exemption of Radium-223 (223Ra) treatment in metastatic hormone-sensitive high-grade prostate cancer (mHSHGPC) patients with concomitant androgen deprivation-therapy (ADT). Seven patients with mHSHGPC, were treated with six cycles of 223Ra plus ADT. All patients had undergone to 18F-NaF-PET/CT. A qualitative analyses of the 18F-NaF PET/CT was performed in conjunction with Alkaline Phosphatase (ALP), Lactate dehydrogenase (LDH) and Prostatic-Specific Antigen (PSA) values. The mean of SUVmax values were used as a quantitative measure of tumoral burden. Changes in PSA, ALP, LDH from baseline were evaluated, and were defined as increase or decrease of at least 30%. Clinical response was achieved if there was pain reduction using visual analogic scale. Four patients showed a significant reduction in mean SUVmax after 3 cycles of 223Ra, and one after 6 cycles. Patients who showed reductions in mean SUVmax after Ra-223 also showed reductions in PSA, ALP and LDH. Four weeks after the last cycle of 223Ra all patients had decreased total PSA, ALP and LDH values >= 30% also significant improvement on pain. No progress disease was documented after 14 +/- 4 weeks. We found slight to moderate decreases in neutrophils and hemoglobin in two patients. We concluded that 223Ra plus ADT can be useful in mHSHGPC; the semi-quantitative 18F-NaF PET/CT as a method effective to monitor the treatment response. Due to concomitant administration of ADT, 18F-NaF-PET/CT cannot differentiate whether the findings were due to androgen blockade or the 223Ra; nevertheless, data supporting the efficacy of 223Ra is the significant improvement on pain. PMID- 29181272 TI - New insights in the use of immunoglobulins for the management of immune deficiency (PID) patients. AB - Immunoglobulin replacement therapy (IRT) is standard treatment for patients with primary immunodeficiency (PID). Because most of the patients with PID will require long life-time immunoglobulin replacement therapy, the quality of the prescribed products is of utmost importance. The IRT is generally administered either intravenously (abbreviated IVIG), or subcutaneously (abbreviated SCIG). Both routes have been demonstrated to be effective. The preferred route may vary at different times during a given patient's life. Options are therefore not fixed and the choice of route for immunoglobulin therapy will depend on several factors, including patient characteristics, clinical indication, venous access, side effects, rural or remote location, treatment compliance and patient preference. Many years ago, immunoglobulin therapy was associated with side effects which may compromise patient's compliance and quality of life of the patients. Most of the side effects were related to impurities. Recently, major advances in the manufacturing process have been made and new processes, such as the Quality by design (QbD) approach were added into the manufacturing steps to ensure patients tolerability and safety. Due to the improved purity of the immunoglobulin products obtained by these processes, the incidence of side effects is lower, while the ways of administration of Ig therapy and the choice of the regimen has widened to suit patient's preference and needs. PMID- 29181273 TI - Optimizing peptide epitope-based autoantibody detection in cancer patients. AB - Autoantibody (autoAb) response is an important arm of endogenously arising anti tumor immune responses, and has received new attention as a cancer biomarker with the recent success of immune check-point inhibitor therapy. Our laboratory has been focusing on measuring autoAb against B-cell epitopes in order to bypass the necessity to purify a panel of recombinant proteins. In order to optimize peptide based autoAb measurement and to increase sensitivities to cover more patients, we developed a new approach of using mixed peptides to conjugate on the same microsphere and compared its results with the use of a dominant peptide epitope using Luminex microbead-based multiplex assays. The peptide epitopes of two cancer/germline antigens, New York esophageal cancer antigen-1 (NY-ESO-1) and X antigen family member-1b (XAGE-1b), and cancer/stem cell antigen, sex determining region Y-box-2 (SOX2), were used as prototypes in this study. Our results indicate that using mixed peptides of B-cell epitopes improves the sensitivity of detecting more patients with autoAb responses. Thus, when the full-length protein is not available for conjugating onto microspheres, a mixture of B-cell epitopes is the method of choice for using Luminex multiplex assay to detect autoAb response in cancer patients.

AB - Major depressive disorder (MDD) is highly prevalent, recurrent, and associated with functional impairment, morbidity, and mortality. Herein, we aimed to identify disruptions in functional connectomics among subjects with MDD by using resting-state functional magnetic resonance imaging (rs-fMRI). Sixteen subjects with MDD and thirty health controls completed resting-state fMRI scans and clinical assessments (e.g., Hamilton Depression Rating Scale (HAMD) and Hospital Anxiety and Depression Scale (HADS)). We found higher amplitude of low frequency fluctuations (ALFF) bilaterally in the hippocampus and amygdala among MDD subjects when compared to healthy controls. Using graph theoretical analysis, we found decreased clustering coefficient, local efficiency, and transitivity in the MDD patients. Our findings suggest a potential biomarker for differentiating individuals with MDD from individuals without MDD. PMID- 29181275 TI - Morphological and molecular data confirm the transfer of homostylous species in the typically distylous genus Galianthe (Rubiaceae), and the description of the new species Galianthe vasquezii from Peru and Colombia. AB - Galianthe (Rubiaceae) is a neotropical genus comprising 50 species divided into two subgenera, Galianthe subgen. Galianthe, with 39 species and Galianthe subgen. Ebelia, with 11 species. The diagnostic features of the genus are: usually erect habit with xylopodium, distylous flowers arranged in lax thyrsoid inflorescences, bifid stigmas, 2-carpellate and longitudinally dehiscent fruits, with dehiscent valves or indehiscent mericarps, plump seeds or complanate with a wing-like strophiole, and pollen with double reticulum, rarely with a simple reticulum. This study focused on two species that were originally described under Diodia due to the occurrence of fruits indehiscent mericarps: Diodia palustris and D. spicata. In the present study, classical taxonomy is combined with molecular analyses. As a result, we propose that both Diodia species belong to Galianthe subgen. Ebelia. The molecular position within Galianthe, based on ITS and ETS sequences, has been supported by the following morphological characters: thyrsoid, spiciform or cymoidal inflorescences, bifid stigmas, pollen grains with a double reticulum, and indehiscent mericarps. However, both species, unlike the remainder of the genus Galianthe, have homostylous flowers, so the presence of this type of flower significantly modifies the generic concept. In this framework, a third homostylous species, Galianthe vasquezii, from the Andean region is also described. Until now, this species remained cryptic under specimens of Galianthe palustris It differs however from the latter by having longer calyx lobes, the presence of dispersed trichomes inside the corolla lobes (vs. glabrous), fruits that are acropetally dehiscent (vs. basipetally dehiscent), and its Andean geographical distribution (vs. Paranaense). Additionally, a lectotype has been chosen for Diodia palustris, Borreria pterophora has been placed under synonymy of Galianthe palustris, and Galianthe boliviana is reported for the first time from Peru. A key of all Galianthe species with indehiscent mericarps is also provided. PMID- 29181276 TI - I-ATAC: interactive pipeline for the management and pre-processing of ATAC-seq samples. AB - Assay for Transposase Accessible Chromatin (ATAC-seq) is an open chromatin profiling assay that is adapted to interrogate chromatin accessibility from small cell numbers. ATAC-seq surmounted a major technical barrier and enabled epigenome profiling of clinical samples. With this advancement in technology, we are now accumulating ATAC-seq samples from clinical samples at an unprecedented rate. These epigenomic profiles hold the key to uncovering how transcriptional programs are established in diverse human cells and are disrupted by genetic or environmental factors. Thus, the barrier to deriving important clinical insights from clinical epigenomic samples is no longer one of data generation but of data analysis. Specifically, we are still missing easy-to-use software tools that will enable non-computational scientists to analyze their own ATAC-seq samples. To facilitate systematic pre-processing and management of ATAC-seq samples, we developed an interactive, cross-platform, user-friendly and customized desktop application: interactive-ATAC (I-ATAC). I-ATAC integrates command-line data processing tools (FASTQC, Trimmomatic, BWA, Picard, ATAC_BAM_shiftrt_gappedAlign.pl, Bedtools and Macs2) into an easy-to-use platform with user interface to automatically pre-process ATAC-seq samples with parallelized and customizable pipelines. Its performance has been tested using public ATAC-seq datasets in GM12878 and CD4+T cells and a feature-based comparison is performed with some available interactive LIMS (Galaxy, SMITH, SeqBench, Wasp, NG6, openBIS). I-ATAC is designed to empower non-computational scientists to process their own datasets and to break to exclusivity of data analyses to computational scientists. Additionally, I-ATAC is capable of processing WGS and ChIP-seq samples, and can be customized by the user for one independent or multiple-sequential operations.

AB - Background: Pertussis is a vaccine-preventable disease, yet an increasing incidence of pertussis occurs in many countries. Thailand has a long-standing pertussis vaccination policy, therefore most expectant mothers today had received vaccines as children. The resurgence of pertussis among Thai infants in recent years led us to examine the pre-existing antibodies to Bordetella pertussis antigens in a cohort of 90 pregnant women. Methods: We evaluated the IgG to the Pertussis toxin (PT), filamentous hemagglutinin (FHA) and pertactin (PRN) in maternal and cord blood sera using commercial enzyme-linked immunosorbent assays (ELISA). Results: When values of >10 IU/ml were accepted as potential protective concentrations, we found that the percentages of unprotected infants were 73.3%, 43.3% and 75.5% for anti-PT, anti-FHA and anti-PRN IgG, respectively. Discussion: These results may explain the susceptibility for pertussis among newborn infants in Thailand and support the requirement for a pertussis booster vaccine during pregnancy, which may contribute to the passive seroprotection among newborns during the first months of life. PMID- 29181280 TI - Associations of IGF2 and DRD2 polymorphisms with laying traits in Muscovy duck. AB - Insulin-like growth factor 2 (IGF2) and dopamine receptor 2 (DRD2) play important roles in ovarian follicular development. In this study, we analyzed tissue specific expression of the Muscovy duck IGF2 and DRD2 genes and cloned those genes transcripts. Polymorphisms in these genes were tightly linked with egg production traits and both genes were highly expressed in the ovary. Moreover, we identified five single nucleotide polymorphisms (SNPs) for IGF1 and 28 for DRD2. Mutations A-1864G and C-1704G of IGF2 were positively correlated with increased egg laying at 59 weeks (E59W) (P < 0.05). The C+7T and C+364G mutations of DRD2 were highly and significantly associated with first-egg age (FEA) and egg numbers at 300 days (E300D) (P < 0.01). Moreover, C+3301G and C+3545G of DRD2 were highly significantly associated with FEA, E59W and E300D (P < 0.01). Other mutations were positively associated with FEA or E300D or E59W (P < 0.05). These data suggest specific roles for IGF1 and DRD2 polymorphisms in egg production in Muscovy ducks. PMID- 29181281 TI - Do rotational shear-cushioning shoes influence horizontal ground reaction forces and perceived comfort during basketball cutting maneuvers? AB - Background: Court shoe designs predominantly focus on reducing excessive vertical ground reaction force, but shear force cushioning has received little attention in the basketball population. We aimed to examine the effect of a novel shoe cushioning design on both resultant horizontal ground reaction forces and comfort perception during two basketball-specific cutting movements. Methods: Fifteen university team basketball players performed lateral shuffling and 45-degree sidestep cutting at maximum effort in basketball shoes with and without the shear cushioning system (SCS). Paired t-tests were used to examine the differences in kinetics and comfort perception between two shoes. Results: SCS shoe allowed for larger rotational material deformation compared with control shoes, but no significant shoe differences were found in braking phase kinetics during both cutting movements (P = 0.35). Interestingly, a greater horizontal propulsion impulse was found with the SCS during 45-degree cutting (P < 0.05), when compared with the control. In addition, players wearing SCS shoes perceived better forefoot comfort (P = 0.012). During lateral shuffling, there were no significant differences in horizontal GRF and comfort perception between shoe conditions (P > 0.05). Discussion: The application of a rotational shear-cushioning structure allowed for better forefoot comfort and enhanced propulsion performance in cutting, but did not influence the shear impact. Understanding horizontal ground reaction force information may be useful in designing footwear to prevent shear related injuries in sport populations.

AB - The advent of next-generation sequencing tools has made it possible to conduct fine-scale surveys of population differentiation and genome-wide scans for signatures of selection in non-model organisms. Such surveys are of particular importance in sharply declining coral species, since knowledge of population boundaries and signs of local adaptation can inform restoration and conservation efforts. Here, we use genome-wide surveys of single-nucleotide polymorphisms in the threatened Caribbean elkhorn coral, Acropora palmata, to reveal fine-scale population structure and infer the major barrier to gene flow that separates the eastern and western Caribbean populations between the Bahamas and Puerto Rico. The exact location of this break had been subject to discussion because two previous studies based on microsatellite data had come to differing conclusions. We investigate this contradiction by analyzing an extended set of 11 microsatellite markers including the five previously employed and discovered that one of the original microsatellite loci is apparently under selection. Exclusion of this locus reconciles the results from the SNP and the microsatellite datasets. Scans for outlier loci in the SNP data detected 13 candidate loci under positive selection, however there was no correlation between available environmental parameters and genetic distance. Together, these results suggest that reef restoration efforts should use local sources and utilize existing functional variation among geographic regions in ex situ crossing experiments to improve stress resistance of this species. PMID- 29181282 TI - Modus operandi and affect in Sweden: the Swedish version of the Regulatory Mode Questionnaire. AB - Background: The Regulatory Mode Questionnaire (RMQ) is the most used and internationally well-known instrument for the measurement of individual differences in the two self-regulatory modes: locomotion (i.e., the aspect of self-regulation that is concerned with movement from state to state) and assessment (i.e., the comparative aspect of self-regulation). The aim of the present study was to verify the independence of the two regulatory modes, as postulated by the Regulatory Mode Theory (Kruglanski et al., 2000), and the psychometric properties of the RMQ in the Swedish context. Furthermore, we investigated the relationship between regulatory modes (locomotion and assessment) and affective well-being (i.e., positive affect and negative affect). Method: A total of 655 university and high school students in the West of Sweden (males = 408 females = 242, and five participants who didn't report their gender; agemean = 21.93 +/- 6.51) responded to the RMQ and the Positive Affect Negative Affect Schedule. We conducted two confirmatory factor analyses using structural equation modeling (SEM). A third SEM was conducted to test the relationship between locomotion and assessment to positive affect and negative affect. Results: The first analyses confirmed the unidimensional factor structure of locomotion and assessment and both scales showed good reliability. The assessment scale, however, was modified by dropping item 10 ("I don't spend much time thinking about ways others could improve themselves".) because it showed low loading (.07, p = .115). Furthermore, the effect of locomotion on positive affect was stronger than the effect of assessment on positive affect (Z = -15.16, p < .001), while the effect of assessment on negative affect was stronger than the effect of locomotion on negative affect (Z = 10.73, p < .001). Conclusion: The factor structure of the Swedish version of the RMQ is, as Regulatory Mode Theory suggests, unidimensional and it showed good reliability. The scales discriminated between the two affective well-being dimensions. We suggest that the Swedish version of the RMQ, with only minor modifications, is a useful instrument to tap individual differences in locomotion and assessment. Hence, the present study contributes to the validation of the RMQ in the Swedish culture and adds support to the theoretical framework of self-regulatory mode. PMID- 29181283 TI - Hydrothermal synthesis of ZnO quantum dot/KNb3O8 nanosheet photocatalysts for reducing carbon dioxide to methanol. AB - ZnO quantum dots and KNb3O8 nanosheets were synthesized by a two-step hydrothermal method for the photocatalytic reduction of CO2 to methanol where isopropanol is simultaneously oxidized to acetone . The as-prepared photocatalysts were characterized by X-ray diffraction (XRD), energy dispersive X ray spectroscopy (EDS), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM) and UV-vis absorption spectroscopy (UV vis). The photocatalytic activity of the materials was evaluated by formation rate of methanol under UV light irradiation at ambient temperature and pressure. The methanol formation rate of pure KNb3O8 nanosheets was found to be 1257.21 MUmol/g/h, and after deposition of 2 wt % ZnO quantum dots on the surface of KNb3O8 nanosheets, the methanol production rate was found to increase to 1539.77 MUmol/g/h. Thus, the ZnO quantum dots obviously prompted separation of charge carriers, which was explained by a proposed mechanism for this photocatalytic reaction. PMID- 29181278 TI - An update on anticancer drug development and delivery targeting carbonic anhydrase IX. AB - The expression of carbonic anhydrase (CA) IX is up-regulated in many types of solid tumors in humans under hypoxic and acidic microenvironment. Inhibition of CA IX enzymatic activity with selective inhibitors, antibodies or labeled probes has been shown to reverse the acidic environment of solid tumors and reduce the tumor growth establishing the significant role of CA IX in tumorigenesis. Thus, the development of potent antitumor drugs targeting CA IX with minimal toxic effects is important for the target-specific tumor therapy. Recently, several promising antitumor agents against CA IX have been developed to treat certain types of cancers in combination with radiation and chemotherapy. Here we review the inhibition of CA IX by small molecule compounds and monoclonal antibodies. The methods of enzymatic assays, biophysical methods, animal models including zebrafish and Xenopus oocytes, and techniques of diagnostic imaging to detect hypoxic tumors using CA IX-targeted conjugates are discussed with the aim to overview the recent progress related to novel therapeutic agents that target CA IX in hypoxic tumors. PMID- 29181284 TI - Fabrication of gold-coated PDMS surfaces with arrayed triangular micro/nanopyramids for use as SERS substrates. AB - Using the tip-based continuous indentation process, arrays of three-dimensional pyramidal cavities have been successfully machined on a copper template and the structures were successfully transferred to a polydimethylsiloxane (PDMS) surface using a reverse nanoimprinting approach. The structured PDMS surface is coated with a thin Au film, and the final substrate is demonstrated as a surface enhanced Raman spectroscopy (SERS) substrate. Rhodamine 6G (R6G) was used as a probe molecule in the present study to confirm the SERS measurements. Arrays of micro/nanostructures of different dimensions were formed by the overlap of pyramidal cavities with different adjacent distances using the tip-based continuous indentation process. The effects of the reverse nanoimprinting process and coating process on the final topography of the structures are studied. The experimental results show that the Raman intensity of the Au-film-coated PDMS substrate is influenced by the topography of the micro/nanostructures and by the thickness of the Au film. The Raman intensity of 1362 cm-1 R6G peak on the structured Au-film-coated PDMS substrate is about 8 times higher than the SERS tests on a commercial substrate (Q-SERS). A SERS enhancement factor ranging from 7.5 * 105 to 6 * 106 was achieved using the structured Au-film-coated PDMS surface, and it was demonstrated that the method proposed in this paper is reliable, replicable, homogeneous and low-cost for the fabrication of SERS substrates. PMID- 29181285 TI - Molecular dynamics simulations of nanoindentation and scratch in Cu grain boundaries. AB - The dynamic nanomechanical characteristics of Cu films with different grain boundaries under nanoindentation and scratch conditions were studied by molecular dynamics (MD) simulations. The type of grain boundary is the main factor in the control of the substrate atoms with respect to the size of dislocations since the existence of the grain boundary itself restricts the movement associated with dislocations. In this work, we analyzed the transverse and vertical grain boundaries for different angles. From the simulation results, it was found that the sample with a transverse grain boundary angle of 20 degrees had a higher barrier effect on the slip band as compared to samples with other angles. Moreover, the nanoindentation results (i.e., indentation on the upper area) of the vertical grain boundary showed that the force was translated along the grain boundary, thereby producing intergranular fractures. PMID- 29181286 TI - Photobleaching of YOYO-1 in super-resolution single DNA fluorescence imaging. AB - Super-resolution imaging of single DNA molecules via point accumulation for imaging in nanoscale topography (PAINT) has great potential to visualize fine DNA structures with nanometer resolution. In a typical PAINT video acquisition, dye molecules (YOYO-1) in solution sparsely bind to the target surfaces (DNA) whose locations can be mathematically determined by fitting their fluorescent point spread function. Many YOYO-1 molecules intercalate into DNA and remain there during imaging, and most of them have to be temporarily or permanently fluorescently bleached, often stochastically, to allow for the visualization of a few fluorescent events per DNA per frame of the video. Thus, controlling the fluorescence on-off rate is important in PAINT. In this paper, we study the photobleaching of YOYO-1 and its correlation with the quality of the PAINT images. At a low excitation laser power density, the photobleaching of YOYO-1 is too slow and a minimum required power density was identified, which can be theoretically predicted with the proposed method in this report. PMID- 29181287 TI - Tailoring the nanoscale morphology of HKUST-1 thin films via codeposition and seeded growth. AB - Integration of surface-anchored metal-organic frameworks (surMOFs) within hierarchical architectures is necessary for potential sensing, electronic, optical, or separation applications. It is important to understand the fundamentals of film formation for these surMOFs in order to develop strategies for their incorporation with nanoscale control over lateral and vertical dimensions. This research identified processing parameters to control the film morphology for surMOFs of HKUST-1 fabricated by codeposition and seeded deposition. Time and temperature were investigated to observe film formation, to control film thickness, and to tune morphology. Film thickness was investigated by ellipsometry, while film structure and film roughness were characterized by atomic force microscopy. Films formed via codeposition resulted in nanocrystallites anchored to the gold substrate. A dynamic process at the interface was observed with a low density of large particulates (above 100 nm) initially forming on the substrate; and over time these particulates were slowly replaced by the prevalence of smaller crystallites (ca. 10 nm) covering the substrate at a high density. Elevated temperature was found to expedite the growth process to obtain the full range of surface morphologies with reasonable processing times. Seed crystals formed by the codeposition method were stable and nucleated growth throughout a subsequent layer-by-layer deposition process. These seed crystals templated the final film structure and tailor the features in lateral and vertical directions. Using codeposition and seeded growth, different surface morphologies with controllable nanoscale dimensions can be designed and fabricated for integration of MOF systems directly into device architectures and sensor platforms. PMID- 29181288 TI - Changes of the absorption cross section of Si nanocrystals with temperature and distance. AB - The absorption cross section (ACS) of silicon nanocrystals (Si NCs) in single layer and multilayer structures with variable thickness of oxide barriers is determined via a photoluminescence (PL) modulation technique that is based on the analysis of excitation intensity-dependent PL kinetics under modulated pumping. We clearly demonstrate that roughly doubling the barrier thickness (from ca. 1 to 2.2 nm) induces a decrease of the ACS by a factor of 1.5. An optimum separation barrier thickness of ca. 1.6 nm is calculated to maximize the PL intensity yield. This large variation of ACS values with barrier thickness is attributed to a modulation of either defect population states or of the efficiency of energy transfer between confined NC layers. An exponential decrease of the ACS with decreasing temperature down to 120 K can be explained by smaller occupation number of phonons and expansion of the band gap of Si NCs at low temperatures. This study clearly shows that the ACS of Si NCs cannot be considered as independent on experimental conditions and sample parameters. PMID- 29181289 TI - Numerical investigation of the tribological performance of micro-dimple textured surfaces under hydrodynamic lubrication. AB - Surface texturing is an important approach for controlling the tribological behavior of friction pairs used in mechanical and biological engineering. In this study, by utilizing the method of three-dimensional computational fluid dynamics (CFD) simulation, the lubrication model of a friction pair with micro-dimple array was established based on the Navier-Stokes equations. The typical pressure distribution of the lubricant film was analyzed. It was found that a positive hydrodynamic pressure is generated in the convergent part of the micro-dimple, while a negative hydrodynamic pressure is generated in the divergent part. With suitable parameters, the total integration of the pressure is positive, which can increase the load-carrying capacity of a friction pair. The effects of the micro dimple parameters as well as fluid properties on tribological performance were investigated. It was concluded that under the condition of hydrodynamic lubrication, the main mechanism for the improvement in the tribological performance is the combined effects of wedging and recirculation. Within the range of parameters investigated in this study, the optimum texture density is 13%, while the optimum aspect ratio varies with the Reynolds number. For a given Reynolds number, there exists a combination of texture density and aspect ratio at which the optimum tribological performance could be obtained. Conclusions from this study could be helpful for the design of texture parameters in mechanical friction components and even in artificial joints. PMID- 29181290 TI - Expanding the molecular-ruler process through vapor deposition of hexadecanethiol. AB - The development of methods to produce nanoscale features with tailored chemical functionalities is fundamental for applications such as nanoelectronics and sensor fabrication. The molecular-ruler process shows great utility for this purpose as it combines top-down lithography for the creation of complex architectures over large areas in conjunction with molecular self-assembly, which enables precise control over the physical and chemical properties of small local features. The molecular-ruler process, which most commonly uses mercaptoalkanoic acids and metal ions to generate metal-ligated multilayers, can be employed to produce registered nanogaps between metal features. Expansion of this methodology to include molecules with other chemical functionalities could greatly expand the overall versatility, and thus the utility, of this process. Herein, we explore the use of alkanethiol molecules as the terminating layer of metal-ligated multilayers. During this study, it was discovered that the solution deposition of alkanethiol molecules resulted in low overall surface coverage with features that varied in height. Because features with varied heights are not conducive to the production of uniform nanogaps via the molecular-ruler process, the vapor-phase deposition of alkanethiol molecules was explored. Unlike the solution-phase deposition, alkanethiol islands produced by vapor-phase deposition exhibited markedly higher surface coverages of uniform heights. To illustrate the applicability of this method, metal-ligated multilayers, both with and without an alkanethiol capping layer, were utilized to create nanogaps between Au features using the molecular-ruler process. PMID- 29181291 TI - Surfactant-induced enhancement of droplet adhesion in superhydrophobic soybean (Glycine max L.) leaves. AB - This study performed with soybean (Glycine max L.), one of the most important crops for human and animal nutrition, demonstrates that changes in the leaf surface structure can increase the adhesion of applied droplets, even on superhydrophobic leaves, to reduce undesirable soil contamination by roll-off of agrochemical formulations from the plant surfaces. The wettability and morphology of soybean (Glycine max L.) leaf surfaces before and after treatment with six different surfactants (Agnique(r) SBO10 and five variations of nonionic surfactants) have been investigated. The leaf surface structures show a hierarchical organization, built up by convex epidermal cells (microstructure) and superimposed epicuticular platelet-shaped wax crystals (micro- to nanostructure). Chemical analysis of the epicuticular wax showed that 1 triacontanol (C30H61OH) is the main wax component of the soybean leaf surfaces. A water contact angle (CA) of 162.4 degrees (sigma = 3.6 degrees ) and tilting angle (TA) of 20.9 degrees (sigma = 10.0 degrees ) were found. Adherence of pure water droplets on the superhydrophobic leaves is supported by the hydrophilic hairs on the leaves. Agnique(r) SBO10 and the nonionic surfactant XP ED 75 increased the droplet adhesion and caused an increase of the TA from 20.9 degrees to 85 degrees and 90 degrees , respectively. Scanning electron microscopy showed that surfactants with a hydrophilic-lipophilic balance value below 10 caused a size reduction of the epicuticular wax structures and a change from Cassie-Baxter wetting to an intermediate wetting regime with an increase of droplet adhesion.

AB - We study mechanically exfoliated nanosheets of franckeite by quantitative optical microscopy. The analysis of transmission-mode and epi-illumination-mode optical microscopy images provides a rapid method to estimate the thickness of the exfoliated flakes at first glance. A quantitative analysis of the optical contrast spectra by means of micro-reflectance allows one to determine the refractive index of franckeite over a broad range of the visible spectrum through a fit of the acquired spectra to a model based on the Fresnel law. PMID- 29181293 TI - Increasing the stability of DNA nanostructure templates by atomic layer deposition of Al2O3 and its application in imprinting lithography. AB - We present a method to increase the stability of DNA nanostructure templates through conformal coating with a nanometer-thin protective inorganic oxide layer created using atomic layer deposition (ALD). DNA nanotubes and origami triangles were coated with ca. 2 nm to ca. 20 nm of Al2O3. Nanoscale features of the DNA nanostructures were preserved after the ALD coating and the patterns are resistive to UV/O3 oxidation. The ALD-coated DNA templates were used for a direct pattern transfer to poly(L-lactic acid) films. PMID- 29181294 TI - Electron beam induced deposition of silacyclohexane and dichlorosilacyclohexane: the role of dissociative ionization and dissociative electron attachment in the deposition process. AB - We present first experiments on electron beam induced deposition of silacyclohexane (SCH) and dichlorosilacyclohexane (DCSCH) under a focused high energy electron beam (FEBID). We compare the deposition dynamics observed when growing pillars of high aspect ratio from these compounds and we compare the proximity effect observed for these compounds. The two precursors show similar behaviour with regards to fragmentation through dissociative ionization in the gas phase under single-collision conditions. However, while DCSCH shows appreciable cross sections with regards to dissociative electron attachment, SCH is inert with respect to this process. We discuss our deposition experiments in context of the efficiency of these different electron-induced fragmentation processes. With regards to the deposition dynamics, we observe a substantially faster growth from DCSCH and a higher saturation diameter when growing pillars with high aspect ratio. However, both compounds show similar behaviour with regards to the proximity effect. With regards to the composition of the deposits, we observe that the C/Si ratio is similar for both compounds and in both cases close to the initial molecular stoichiometry. The oxygen content in the DCSCH deposits is about double that of the SCH deposits. Only marginal chlorine is observed in the deposits of from DCSCH. We discuss these observations in context of potential approaches for Si deposition. PMID- 29181295 TI - Supravaginal hysterectomy in Curacao prevalence and impact on screening for cervical cancer. AB - In Curacao, hysterectomies are frequently performed. A common reason for this procedure is the high incidence of leiomyomatosis. However in some cases the cervix is conserved. Following supravaginal hysterectomy most women discontinue cervical cancer screening because they think the cervix is not conserved. We aimed to get insight in the proportion of supravaginal hysterectomies and the level of awareness on the necessity to continue with cervical cancer screening in case of retained cervix. In 2014, data from all hysterectomies performed between 2003 and 2013 on Curacao were collected. Information about: type of hysterectomy (supravaginal or not), age of the patient, reason for a hysterectomy and incidence of cervical cancer post-hysterectomy were obtained from the nationwide pathology database. In addition, 600 hysterectomised volunteers answered a questionnaire in which the awareness of their type of hysterectomy and continuation of screening for cervical cancer after surgery were investigated. In the at-risk population (>= 15 years old), 6.0 per1000 women (95% CI 5.9-6.2) had a hysterectomy between 2003 and 2013 (n = 692,304). From the performed hysterectomies, 2.9% were supravaginal and no cases of cervical cancer post hysterectomy were reported. The majority (55.3%) of women were unaware of their cervical status post-hysterectomy. About one-third (34.3%) of these women had their last Pap-smear pre-hysterectomy. Information campaigns are needed to raise awareness in women, to continue cervical-screening after supravaginal hysterectomy. PMID- 29181296 TI - A systematic review of physical activity interventions to improve physical fitness and health outcomes among Indigenous adults living in Canada. AB - : The Indigenous population of Canada faces an increased burden of chronic disease, leading to decreased life expectancy. Physical activity is an important health behaviour that improves chronic disease risk factors and physical fitness. The objective of this systematic review was to evaluate physical activity interventions in the Indigenous population in Canada to determine effects on physical activity rates, physical fitness, and health outcomes. MEDLINE, PsycINFO, EMBASE, and CINAHL were searched for peer-reviewed journal articles. Inclusion criteria were studies that examined a physical activity intervention delivered in Indigenous communities in Canada for adults over 18 years of age. Data was extracted and two authors independently rated quality of the evidence. Five studies were included in the narrative synthesis. Interventions were community-based, and three were multi-component interventions focused on preventing or managing type II diabetes. The interventions varied in their success in altering physical activity rates, with increases (n = 2), a decrease (n = 1), or non-significant changes reported (n = 2). No study reported any measure of physical fitness. BMI was reported in four studies, with only one reporting a significant decrease. Decreases in systolic blood pressure and total cholesterol were reported in two studies. There is limited evidence and a lack of robust interventions that examine the impacts of physical activity on health and fitness status in the Canadian Indigenous population. Validated, culturally relevant tools for measuring physical activity may aid in program evaluation and focused educational materials could better support population health initiatives. Trial registration: The review protocol was registered prospectively with PROSPERO (registration number: CRD42017055363). PMID- 29181297 TI - The ability of triggers to retrospectively predict potentially preventable adverse events in a sample of deceased patients. AB - Several trigger systems have been developed to screen medical records of hospitalized patients for adverse events (AEs). Because it's too labor-intensive to screen the records of all patients, usually a sample is screened. Our sample consists of patients who died during their stay because chances of finding preventable AEs in this subset are highest. Records were reviewed for fifteen triggers (n = 2182). When a trigger was present, the records were scrutinized by specialized medical doctors who searched for AEs. The positive predictive value (PPV) of the total trigger system and of the individual triggers was calculated. Additional analyses were performed to identify a possible optimization of the trigger system. In our sample, the trigger system had an overall PPV for AEs of 47%, 17% for potentially preventable AEs. More triggers present in a record increased the probability of detecting an AE. Adjustments to the trigger system slightly increased the positive predictive value but missed about 10% of the AEs detected with the original system. In our sample of deceased patients the trigger system has a PPV comparable to other samples. However still, an enormous amount of time and resources are spent on cases without AEs or with non-preventable AEs. Possibly, the performance could be further improved by combining triggers with clinical scores and laboratory results. This could be promising in reducing the costly and labor-intensive work of screening medical records. PMID- 29181298 TI - Physical activity and park use of youth in Nanchang, China. AB - Physical inactivity is a growing issue in Chinese youth, but parks can facilitate traditional and non-traditional forms of physical activity for little to no cost. Despite this opportunity, very little is known regarding park use among Chinese youth. The purpose of this study was to conduct a cross-sectional observational study of park usage and physical activity of youth in municipal parks in Nanchang, China. Data were collected in June of 2014 in eight parks across Nanchang, Jiangxi a large city in southeast China. Physical activity was measured by a modified version of System for Observing Play and Recreation in Communities. Ordered hierarchic generalized linear models were estimated using a logit link function. The influence of the park was estimated using random effects, with fixed effects and park, environmental, and park user characteristics. Youth were most often seen active in the afternoon, on weekends, and during cooler times (<= 29 degrees C). Paradoxically, more children were active when air quality was poorer. Older boys were more active than younger boys, but no differences were observed in girls. More children were seen active in unstructured play compared to structured activities. The results suggest parks are an important setting for physical activity among Chinese youth, and that unstructured activities can play an important role in promoting greater youth physical activity. PMID- 29181299 TI - Persistent bacteremia secondary to delayed identification of Lactobacillus in the setting of mitral valve endocarditis. AB - Introduction: Lactobacillus species causing infective endocarditis is rare. Most reported cases arise from the oral ingestion of Lactobacillus via dairy or nutritional supplements in patients with congenital valve disease or replacement. We present a case of native valve bacterial endocarditis caused by Lactobacillus arising from dental abscesses. Additionally, there was an error in identification of the Lactobacillus as Corynebacterium, which led to inadequate treatment. Presentation of case: A 51-year-old male presented to an outside clinic with several weeks of subjective fevers and malaise. The provider obtained two sets of blood cultures. Both grew Gram-positive bacilli identified as Corynebacterium. Once hospitalized he persistently had positive blood cultures despite treatment with vancomycin and gentamicin. The specimens were sent to a reference lab. The cultures were confirmed to be Lactobacillus zeae resistant to vancomycin and gentamicin. Once he was started on appropriate therapy his blood cultures showed no further growth of bacteria. The infected teeth were removed as it was felt they were the source of the bacteremia. Discussion: This case presents two interesting topics in one encounter. First, Lactobacillus is not a common culprit in endocarditis. Secondly, the incorrect identification of the gram-positive bacilli bacteria led to prolonged bacteremia in our patient. Conclusion: The patient was evaluated by cardiothoracic surgery at our facility and it was determined that he would likely need a mitral valve replacement versus repair. The decision was made to treat the patient with six weeks Penicillin-VK prior to the operation. He is currently completing his antibiotic therapy. PMID- 29181300 TI - Recurrence of Escherichia coli meningitis in a preterm infant and co-infection of echovirus 18. AB - Introduction: Bacterial meningitis may relapse after adequate antibiotic treatment. In most cases, however, the pathophysiology cannot be identified. Presentation of case: We describe a preterm infant with recurrent episodes of meningitis due to infection with an identical Escherichia coli strain both at birth and at 10 days after cessation of a 3 week course of appropriate antibiotic treatment. At the time of recurrence, the patient presented with fulminant severe cardiac failure due to acute myocarditis, coupled with a concurrent echovirus 18 infection (confirmed by stool culture and serological analysis). Conclusion: Co infection by echovirus may underlie recurrence of Escherichia coli meningitis in this case.

AB - AIM: To investigate whether DNA vaccine encoding herpes simplex virus 1 (HSV-1) glycoprotein C (gC) and glycoprotein D (gD) will achieve better protective effect against herpes simplex keratitis (HSK) than DNA vaccine encoding gD alone. METHODS: DNA vaccine expressing gD or gC combined gD (gD.gC) were constructed and carried by chitosan nanoparticle. The expression of fusion protein gD and gC were detected in DNA/nanoparticle transfected 293T cells by Western-blot. For immunization, mice were inoculated with DNA/nanoparticle for 3 times with 2wk interval, and two weeks after the final immunization, the specific immune responses and clinical degrees of primary HSK were evaluated. RESULTS: Fusion protein gD.gC could be expressed successfully in cultured 293T cells. And, pRSC gC.gD-IL21 DNA/chitosan nanoparticle could effectively elicit strongest humoral and cellular immune response in primary HSK mice evidenced by higher levels of specific neutralizing antibody and sIgA production, enhanced cytotoxicities of splenocytes and nature killer cells (NK), when compared with those of gD alone or mocked vaccine immunized mice. As a result, gC-based vaccine immunized mice showed least HSK disease. CONCLUSION: gC-based DNA vaccine could effectively prevent the progress of primary HSK, suggesting that this DNA vaccine could be a promising vaccine for HSK treatment in the future. PMID- 29181305 TI - Histopathologic findings of keratoconus corneas underwent penetrating keratoplasty according to topographic measurements and keratoconus severity. AB - AIM: To investigate the histopathologic and morphological changes of the corneas with keratoconus (KC) undergoing penetrating keratoplasty (PKP) according to topographic findings and severity of KC. METHODS: The corneal tissue of 35 samples with KC was retrospectively evaluated with conventional light microscopy. Topographic and pachymetric parameters of keratoconus corneas by means of Pentacam such as mean keratometry (K) and central corneal thickness (CCT) were recorded. Severity of KC was graded according to Amsler-Krumeich classification. RESULTS: Epithelial thinning and breaks in Bowman's layer are the most common findings in keratoconus corneas (94.3% and 82.9% corneas, respectively). The results revealed statistically significant higher mean K value and lower CCT in the keratoconus corneas that were affected by epithelial thinning, breaks in the Bowman's layer, folds in the Descemet's membrane, epithelial scars, breaks in Descemet's membrane, and stromal scars than those corneas without these findings (P<0.05). Moreover, those corneas with epithelial thinning, breaks in the Bowman's layer, folds in Descemet's membrane, epithelial scars, and stromal scars had significantly more severe disease than those corneas without these findings (P<0.05). The presence of the stromal and epithelial scars were associated with the higher KC severity, in which, respectively, 87.5% and 80.0% of the corneas with stromal and epithelial scars had stage 4 of the KC severity. CONCLUSION: It seems that there are some specific patterns in histologic changes of the keratoconus corneas. The presence of pathologic findings was correlated with thinner and steeper corneas. Epithelial or stromal scars were associated with the highest disease severity. The description of histopathologic findings of KC may help in elucidating the pathogenesis of the disease and help pathologist in differentiating KC from other corneal diseases. PMID- 29181306 TI - Effect of itraconazole on the cornea in a murine suture model and penetrating keratoplasty model. AB - AIM: To investigate the anti-(lymph)angiogenic and/or anti-inflammatory effect of itraconazole in a corneal suture model and penetrating keratoplasty (PK) model. METHODS: Graft survival, corneal neovascularization, and corneal lymphangiogenesis were compared among itraconazole, amphotericin B, dexamethasone, phosphate buffered saline (PBS) and surgery-only groups following subconjunctival injection in mice that underwent PK and corneal suture. Immunohistochemical staining and analysis were performed in each group. Real-time polymerase chain reaction (RT-PCR) was performed to quantify the expression of inflammatory cytokines (TNF-alpha, IL-6) and vascular endothelial growth factor (VEGF)-A, VEGF-C, VEGFR-2, and VEGFR-3. RESULTS: In the suture model, the itraconazole group showed less angiogenesis, less lymphangiogenesis, and less inflammatory infiltration than the PBS group (all P<0.05). The itraconazole group showed reduced expression of VEGF-A, VEGFR-2, TNF-alpha, IL-6 than the PBS group (all P<0.05). In PK model, the two-month graft survival rate was 28.57% in itraconazole group, 62.50% in dexamethasone group, 12.50% in PBS group, 0 in amphotericin B group and 0 in surgery-only group. Graft survival in the itraconazole group was higher than that in the amphotericin, PBS and surgery-only group (P=0.057, 0.096, 0.012, respectively). The itraconazole group showed less total angiogenesis and lymphangiogenesis than PBS group (all P<0.05). CONCLUSION: Itraconazole decrease neovascularization, lymphangiogenesis, and inflammation in both a corneal suture model and PK model. Itraconazole has anti-(lymph) angiogenic and anti-inflammatory effects in addition to its intrinsic antifungal effect and is therefore an alternative treatment option in cases where steroids cannot be used. PMID- 29181307 TI - Expression of multidrug resistance proteins in retinoblastoma. AB - AIM: To elucidate the mechanism of multidrug resistance in retinoblastoma, and to acquire more insights into in vivo drug resistance. METHODS: Three anticancer drug resistant Y79 human RB cells were generated against vincristine, etoposide or carboplatin, which are used for conventional chemotherapy in RB. Primary cultures from enucleated eyes after chemotherapy (PCNC) were also prepared. Their chemosensitivity to chemotherapeutic agents (vincristine, etoposide and carboplatin) were measured using MTT assay. Western blot analysis was performed to evaluate the expression of p53, Bcl-2 and various multidrug resistant proteins in retinoblastoma cells. RESULTS: Following exposure to chemotherapeutic drugs, PCNC showed less sensitivity to drugs. No significant changes observed in the p53 expression, whereas Bcl-2 expression was found to be increased in the drug resistant cells as well as in PCNC. Increased expression of P-glycoprotein (P-gp) was observed in drug resistant Y79 cells; however there was no significant change in the expression of P-gp found between primary cultures of primarily enucleated eyes and PCNC. Multidrug resistance protein 1 (Mrp-1) expression was found to be elevated in the drug resistant Y79 cells as well as in PCNC. No significant change in the expression of lung resistance associated protein (Lrp) was observed in the drug resistant Y79 cells as well as in PCNC. CONCLUSION: Our results suggest that multidrug resistant proteins are intrinsically present in retinoblastoma which causes treatment failure in managing retinoblastoma with chemotherapy. PMID- 29181308 TI - Protective effect of pomegranate juice on retinal oxidative stress in streptozotocin-induced diabetic rats. AB - AIM: To investigate the effect of pomegranate juice (PJ) intake on overall oxidation status in retinas of diabetic rats. METHODS: Twenty-seven rats were divided into four groups as control (CO), diabetic (DM), control treated with PJ (CO-PJ), and diabetic treated with PJ (DM-PJ).The retina tissues were used to determine 8-hydroxy-2'-deoxyguanosine (8OHdG), malondialdehyde (MDA), reduced glutathione (GSH) levels, and the enzyme activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). RESULTS: The levels of 8OHdG and MDA were significantly increased in the retina of DM group compared to CO group (P=0.001, P<0.001 respectively). Both 8OHdG and MDA levels were decreased in PJ-DM group compared to DM group (P=0.004, P<0.001 respectively). The activities of antioxidant enzymes GSH, SOD, and GDH-Px were significantly decreased in the retina of DM group compared to CO group (P<=0.01). GSH and GSH-Px activities were higher in PJ-DM group compared with DM group (P=0.010, P=0.042, respectively) but SOD activity was not statistically different (P=0.938). CONCLUSION: PJ intake is found to be effective in decreasing oxidative end products, and in increasing the activities of antioxidant enzymes in diabetic retinas of rats, which suggests it may be effective against oxidative stress in diabetic retinas. PMID- 29181309 TI - Effect of mistletoe combined with carboxymethyl cellulose on dry eye in postmenopausal women. AB - AIM: To investigate the protective effect of mistletoe combined with carboxymethyl cellulose eye drops on dry eye in postmenopausal women. METHODS: Sixty postmenopause female patients diagnosed of dry eye were assigned randomly to mistletoe combined with carboxymethyl cellulose eye drops treatment group (n=30) and control group treated with normal saline eye drops (n=30). The subjective symptoms of ocular surface, Ocular Surface Disease Index (OSDI), tear film function tests, tear protein and corneal morphology by confocal scanning microscopy were analyzed before treatment and at 1, 2, 4 and 8wk after treatment respectively. To ensure the safety of the trial, all patients were examined with systolic pressure, diastolic pressure, glutamic-pyruvic transaminase, glutamic oxaloacetic transaminase, urine creatinine, and blood urea nitrogen at 8wk after treatment. RESULTS: There were no obvious differences between two groups before the treatment (P>0.05). In two months after the treatment, the symptoms of ocular surface, OSDI, tear protein, and tear film function were only slightly changed in normal saline eye drops group. However, all indices were improved after the treatment of mistletoe combined with carboxymethyl cellulose eye drops group (P<0.05). In addition, the average amount of corneal epithelium basal cells and inflammatory cells of mistletoe treated group were 3174+/-379 and 38+/-25 cells/mm2, significantly decreased as compared to the control group with 4309+/ 612 and 158+/- 61 cells/mm2, respectively. In the control group, although nerves still maintained straight under corneal epithelium, the number of nerves were significantly decreased, as compared with normal female. In the mistletoe treated group, the number of nerves was only slightly reduced, compared with normal female. CONCLUSION: Mistletoe combined with carboxymethyl cellulose eye drops can alleviate the symptoms and signs of dry eye symptoms. PMID- 29181310 TI - Femtosecond laser corneal refractive surgery for the correction of high myopic anisometropic amblyopia in juveniles. AB - AIM: To evaluate the effects of femtosecond laser-assisted in situ keratomileusis (FS-LASIK) and small-incision lenticule extraction (SMILE) to correct high myopic anisometropic amblyopia in juvenile patients. METHODS: From November 2013 to January 2015, 33 amblyopic patients with high myopic anisometropic amblyopia were studied. FS-LASIK (30 eyes) or SMILE (3 eyes) was performed in the amblyopic eyes. Visual acuity, refraction, contrast sensitivity, stereoacuity and complications were evaluated. Patients completed follow-up examinations at 3d, 1mo, 3mo and the last follow-up time (mean 8.17+/-3.23mo) after surgery. RESULTS: The mean age at surgery was 9.04+/-3.04y (range 6-16y). The mean spherical equivalent in the amblyopic eyes was significantly decreased from -10.00+/-2.39 D preoperatively to -0.06+/-1.06 D at 1mo, -0.19+/-1.33 D at 3mo and -0.60+/-1.43 D at approximately 8mo postoperatively (P<0.05 for all). The mean myopic anisometropia was significantly decreased from -9.45+/-2.33 D preoperatively to +0.37+/-1.48 D at 1mo, -0.46+/-1.47 D at 3mo and -0.09+/-1.83 D at approximately 8mo (P<0.05 for all). The logarithm of the minimum angle of resolution (logMAR) for uncorrected and corrected distance visual acuity (UDVA and CDVA, respectively) of the amblyopic eye improved from 1.74+/-0.35 and 0.98+/-0.63 preoperatively to 0.45+/-0.31 and 0.41+/-0.33 at approximately 8mo after surgery, respectively. The logMAR CDVA at 3d, 1, 3 and 8mo postoperatively improved by means of 1.42, 2.22, 2.96, and 4.39 lines, and a gain of more than two lines accounted for 45%, 50%, 74% and 86% of all patients, respectively. The contrast sensitivity of both amblyopic eyes and dominant eyes at 0.5, 2, 8 cycles per degree was significantly improved postoperatively (P<0.05 for all). Of the 33 pediatric patients, no patients had near stereopsis preoperatively and seven patients (21.2%) recovered near stereopsis (400" to 60") at approximately 8mo after surgery. No intraoperative or postoperative complications occurred in any patient. CONCLUSION: FS-LASIK or SMILE can be promising alternative methods to correct high myopic anisometropic amblyopia in juvenile patients who have failed with traditional approaches. PMID- 29181311 TI - Scanning-slit topography in patients with keratoconus. AB - AIM: To evaluate the anterior and posterior corneal surfaces using scanning-slit topography and to determine the diagnostic ability of the measured corneal parameters in keratoconus. METHODS: Orbscan II measurements were taken in 39 keratoconic corneas previously diagnosed by corneal topography and in 39 healthy eyes. The central minimum, maximum, and astigmatic simulated keratometry (K) and anterior axial power values were determined. Spherical and cylindrical mean power diopters were obtained at the central and at the steepest point of the cornea both on anterior and on posterior mean power maps. Pachymetry evaluations were taken at the center and paracentrally in the 3 mm zone from the center at a location of every 45 degrees. Receiver operating characteristic (ROC) analysis was used to determine the best cut-off values and to evaluate the utility of the measured parameters in identifying patients with keratoconus. RESULTS: The minimum, maximum and astigmatic simulated K readings were 44.80+/-3.06 D, 47.17+/ 3.67 D and 2.42+/-1.84 D respectively in keratoconus patients and these values differed significantly (P<0.0001 for all comparisons) from healthy subjects. For all pachymetry measurements and for anterior and posterior mean power values significant differences were found between the two groups. Moreover, anterior central cylindrical power had the best discrimination ability (area under the ROC curve=0.948). CONCLUSION: The results suggest that scanning-slit topography and pachymetry are accurate methods both for keratoconus screening and for confirmation of the diagnosis. PMID- 29181312 TI - Phacoemulsification combined with transpupillary removal of silicone oil and intracapsular intraocular lens implantation. AB - AIM: To estimate the effectiveness of phacoemulsification and foldable intraocular lens (IOL) implantation combined with transpupillary silicone oil removal. METHODS: There were 168 eyes of 168 candidate patients with cataract and silicone oil-filled eyes recruited in our study. All of the patients received the intraocular silicone oil removal surgery by transpupillary drainage and cataract extraction by phacoemulsification. Then the IOL implantation were also performed through corneal incision. RESULTS: The surgery was successfully completed in all eyes. Best corrected visual acuity (BCVA) and postoperative complications were recorded in three months after surgery. There were 143 eyes with BCVA improved, otherwise 25 eyes remained stable at the last follow-up visit. The mean BCVA statistically improved from 20/400+/-0.02 to 20/100+/-0.15 (P<0.001) and mean postoperative IOP was 13.85+/-2.18 mm Hg (P=0.415). No intra-operative complications were reported. CONCLUSION: Phacoemulsification combined with transpupillary removal of silicone oil is a safe and simple effective method. In general, it enables quick recovery of visual acuity with less complication rate. PMID- 29181313 TI - Prospective study of Centurion(r) versus Infiniti(r) phacoemulsification systems: surgical and visual outcomes. AB - AIM: To evaluate surgical outcomes (SOs) and visual outcomes (VOs) in cataract surgery comparing the Centurion(r) phacoemulsification system (CPS) with the Infiniti(r) phacoemulsification system (IPS). METHODS: Prospective, consecutive study in a single-site private practice. Totally 412 patients undergoing cataract surgery with either the CPS using the 30-degree balanced(r) tip (n=207) or the IPS using the 30-degree Kelman(r) tip (n=205). Intraoperative and postoperative outcomes were documented prospectively up to one month follow-up. Nuclear sclerosis (NS) grade, cumulated dissipated energy (CDE), preoperative corrected distance visual acuity (CDVA), and CDVA at one month were recorded. RESULTS: CDE was 13.50% less in the whole CPS compared with the whole IPS subcohort. In eyes with NS grade III or greater, CDE was 28.87% less with CPS (n=70) compared with IPS (n=44) (P=0.010). Surgical complications were not statistically different between the two subcohorts (P=0.083), but in the one case of vitreous loss using the CPS, CDVA of 6/4 was achieved at one month. The mean CDVAs (VOs) at one month for NS grade III and above cataracts were -0.17 logMAR (6/4.5) in the CPS and 0.15 logMAR (6/4.5) in the IPS subcohort respectively (P=0.033). CONCLUSION: CDE is 28.87% less, and VOs are significantly improved, in denser cataracts in the CPS compared with the IPS. The authors recommend the CPS for cases with denser nuclei. PMID- 29181314 TI - Repeatability of Ophtha Top topography and comparison with IOL-Master and LenstarLS900 in cataract patients. AB - AIM: To determine the repeatability of Ophtha Top topography and assess the consistency with intraocular lens (IOL)-Master and LenstarLS900 (Lenstar) in measuring corneal parameters among cataract patients. METHODS: Totally 125 eyes were enrolled. Corneas were successively measured with Ophtha Top, IOL-Master and Lenstar at least three times. The flattest meridian power (Kf), the steepest meridian power (Ks), mean power (Km), J0 and J45 were recorded. Intra-class correlation coefficients (ICCs), the coefficient of variance (COV), within subject standard deviation (Sw), and test-retest repeatability (2.77Sw) were adopted to determine the repeatability. The 95% limit of agreement (95%LOA) and Bland-Altman plots were used to assess comparability. RESULTS: Repeatability of Ophtha Top topography for measuring corneal parameters showed the ICCs were all above 0.93, 2.77Sw was lower than 0.31, and the COV of the Kf and Ks was lower than 0.25. The keratometric readings with Ophtha Top topography were flatter than with the IOL-Master and Lenstar devices, while the Pearson correlation coefficients were over 0.97. The J0 and J45 with Ophtha Top topography were smaller compared with Lenstar and IOL-Master, while was comparable between Lenstar and IOL-Master. CONCLUSION: Ophtha Top topography shows excellent repeatability for measuring corneal parameters. However, differences between the Ophtha TOP topography and Lenstar, IOL-Master both in cornea curvature and the astigmatism should be noted clinically. PMID- 29181315 TI - Bimanual microincision cataract surgery with implantation of the new Incise(r) MJ14 intraocular lens through a 1.4 mm incision. AB - AIM: To analyze the visual outcomes and the posterior capsule opacification (PCO) with the new Incise(r) MJ14 intraocular lens (IOL) implanted through a 1.4 mm clear corneal incision (CCI) in patients who underwent bimanual microincision cataract surgery (B-MICS). METHODS: Eighty eyes which underwent cataract surgery using B-MICS technique performed by the same experienced surgeon were included in the study: 40 eyes were implanted with an Incise(r) MJ14 IOL through a 1.4 mm CCI (group A) without enlargement of the main CCI, while 40 eyes were implanted with an Akreos(r) MI60 IOL with enlargement of the main CCI to 1.8 mm (group B). Best corrected visual acuity (BCVA), astigmatism and endothelial cell loss were evaluated before and after surgery at 7, 30d and 6mo. Anterior segment-optical coherence tomography (AS-OCT) of CCI was performed at 1, 3, 7, 30d, 6 and 18mo. PCO incidence was evaluated at 18mo using EPCO 2000 Software. RESULTS: Mean BCVA improvement and endothelial cell loss were statistically significant at 18mo in both groups with no difference between the two groups; no statistically significant difference in surgically induced astigmatism (SIA) was noticed in the two groups. At AS-OCT the only significant alterations in the CCI were endothelial gaping and local detachment of Descemet's membrane at 1 and 7d after surgery; no statistically significant alterations were found at 1, 6 and 18mo. PCO score at 18mo was 0.03+/-0.07 for group A and 0.08+/-0.18 for group B (P=0.11) with no sign of central optic plate invasion in both groups. CONCLUSION: The implant of the new Incise(r) MJ14 IOL through a 1.4 mm CCI and B-MICS technique appeared to be a safe and effective procedure with rapid visual recovery. PCO rate resulted very low and the CCI presented few morphological alterations which were only detectable in the first days postoperatively and achieved fast corneal healing during the long-term follow-up. PMID- 29181316 TI - The prognostic value of lymphocyte-to-monocyte ratio in retinopathy of prematurity. AB - AIM: To evaluate the associations between development of retinopathy of prematurity (ROP) and serum lymphocyte-to-monocyte ratio (LMR), neutrophil-to lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR). METHODS: A retrospective cohort study was performed, involving infants who were screened for ROP from January 2015 to December 2015. Preterm newborns of <=32 gestational weeks with ROP were enrolled as the observation group, and non-ROP infants were enrolled as the control group, whose complete blood cell were measured within the first 24h of life. The levels of NLR, LMR and PLR were determined in all groups. The data obtained were analyzed using univariate and multivariate logistic regression analysis. RESULTS: In this study, 40 cases of ROP were enrolled and 40 cases of non-ROP as controls. The LMR levels were significantly higher (P<0.001) in ROP group (3.96+/-1.16) compared to non-ROP group (2.85+/-0.79). The NLR levels were significantly lower (P=0.035) in ROP group {median [interquartile range (IQR)], 0.88 (0.67-1.46)} compared to non-ROP group [median (IQR), 1.20 (0.85-1.89)]. The median PLR values were 61.99 (IQR, 50.23-75.98) in ROP group and 69.24 (IQR, 55.52-88.12) in non-ROP group (P=0.104). Logistic regression analysis suggested that LMR was an independent risk factor for ROP (OR: 0.275; 95% CI: 0.134-0.564; P=0.001). CONCLUSION: The findings demonstrate that higher LMR is independently and significantly associated with the development of ROP, and the LMR may be invoked as a predictive tool for identifying risk for ROP. PMID- 29181317 TI - A predictive score for retinopathy of prematurity by using clinical risk factors and serum insulin-like growth factor-1 levels. AB - AIM: To detect the impact of insulin-like growth factor-1 (IGF-1) and other risk factors for the early prediction of retinopathy of prematurity (ROP) and to establish a scoring system for ROP prediction by using clinical criteria and serum IGF-1 levels. METHODS: The study was conducted with 127 preterm infants. IGF-1 levels in the 1st day of life, 1st, 2nd, 3rd and 4th week of life was analyzed. The score was established after logistic regression analysis, considering the impact of each variable on the occurrences of any stage ROP. A validation cohort containing 107 preterm infants was included in the study and the predictive ability of ROP score was calculated. RESULTS: Birth weights (BW), gestational weeks (GW) and the prevalence of breast milk consumption were lower, respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD) and necrotizing enterocolitis (NEC) were more frequent, the duration of mechanical ventilation and oxygen supplementation was longer in patients with ROP (P<0.05). Initial serum IGF-1 levels tended to be lower in newborns who developed ROP. Logistic regression analysis revealed that low BW (<1250 g), presence of intraventricular hemorrhage (IVH) and formula feeding increased the risk of ROP. Afterwards, the scoring system was validated on 107 infants. The negative predictive values of a score less than 4 were 84.3%, 74.7% and 79.8% while positive predictive values were 76.3%, 65.5% and 71.6% respectively. CONCLUSION: In addition to BW <1250 g and IVH, formula consumption was detected as a risk factor for the development of ROP. Breastfeeding is important for prevention of ROP in preterm infants. PMID- 29181318 TI - Validity of automated refraction after segmented refractive multifocal intraocular lens implantation. AB - AIM: To evaluate the clinical utility of automated refraction (AR) and keratometry (KR) compared with subjective or manifest refraction (MR) after cataract or refractive lens exchange surgery with implantation of Lentis Mplus X (Oculentis GmbH) refractive multifocal intraocular lens (IOL). METHODS: Eighty six eyes implanted with the Lentis Mplus X multifocal IOL were included. MR was performed in all patients followed by three consecutive AR measurements using the Topcon KR-8000 autorefractor. Assessment of repeatability of consecutive AR before and after dilation with phenylephrine 10%, and comparison of the AR and KR with MR using vector analysis were performed at 3mo follow-up. RESULTS: Analysis showed excellent repeatability of the AR measurements. Linear regression of AR versus MR showed good correlation for sphere and spherical equivalent, whereas the correlation for astigmatism was low. The mean difference AR-MR was -1.28+/ 0.29 diopters (D) for sphere. Astigmatism showed better correlation between KR and MR. CONCLUSION: We suggest AR sphere plus 1.25 D and the KR cylinder as the starting point for MR in eyes with a Lentis Mplus X multifocal IOL. If AR measurements are equal to MR, decentration of the IOL should be suspected. PMID- 29181319 TI - The effect of cataract surgery on sleep quality: a systematic review and Meta analysis. AB - AIM: To evaluate the effect of cataract surgery on sleep quality and to compare the difference between ultraviolet-blocking clear intraocular lens (UVB-IOL) and blue-filtering intraocular lens (BF-IOL) implantation. METHODS: Electronic search was performed of PubMed, MEDLINE, Embase and the Cochrane Library up to January 2016. Studies were eligible when they evaluated the sleep quality before and after cataract surgery by Pittsburgh sleep quality index (PSQI). A random/fixed effects Meta-analysis was used for the pooled estimate. Heterogeneity was assessed with the I2 test. RESULTS: Six studies were selected from 5623 references. Cataract surgery significantly reduced the PSQI scores at postoperative 0-3mo [mean difference (MD) =-0.62, 95%CI: -1.14 to -0.11, P=0.02, I2=66%] and 3-12mo (MD=-0.32, 95%CI: -0.62 to -0.02, P=0.04, I2=0), respectively. Considering different intraocular lens (IOL) implantations, relative post operative PSQI reduction was found for both UVB-IOL and BF-IOL, but a significant reduction was detected only for UVB-IOL. No significant difference was found with the effect of BF-IOL vs UVB-IOL on sleep quality. CONCLUSION: This study found that cataract surgery significantly improved the PSQI score-derived subjective sleep quality irrespective of the IOL type implanted. These findings highlight a substantial benefit of cataract surgery on systemic health with photoreceptive restoration in addition to visual acuity improvements. PMID- 29181320 TI - Predictive factors of visual function recovery after pituitary adenoma resection: a literature review and Meta-analysis. AB - AIM: To determine the dominant predictive factors of postoperative visual recovery for patients with pituitary adenoma. METHODS: PubMed, Google Scholar, Web of Science and Cochrane Library were searched for relevant human studies, which investigated the prediction of the postoperative visual recovery of patients with pituitary adenoma, from January 2000 to May 2017. Meta-analyses were performed on the primary outcomes. After the related data were extracted by two independent investigators, pooled weighted mean difference (WMD) and odds ratio (OR) with 95% confidence interval (CI) were estimated using a random effects or a fixed-effects model. RESULTS: Nineteen studies were included in the literature review, and nine trials were included in the Meta-analysis, which comprised 530 patients (975 eyes) with pituitary adenoma. For the primary outcomes, there was a significant difference between preoperative and postoperative mean deviation (MD) values of the visual field (WMD -5.85; 95%CI: 8.19 to -3.51; P<0.00001). Predictive characteristics of four factors were revealed in this Meta-analysis by assigning the patients to sufficient and insufficient groups according to postoperative visual field improvements, including preoperative visual field defect (WMD 10.09; 95%CI: 6.17 to 14.02; P<0.00001), patient age (WMD -12.32; 95%CI: -18.42 to -6.22; P<0.0001), symptom duration (WMD -5.04; 95%CI: -9.71 to -0.37; P=0.03), and preoperative peripapillary retinal nerve fiber layer (pRNFL) thickness (OR 0.1; 95% CI: 0.04 to 0.23; P<0.00001). CONCLUSION: Preoperative visual field defect, symptom duration, patient age, and preoperative pRNFL thickness are the dominant predictive factors of the postoperative recovery of the visual field for patients with pituitary adenoma.

AB - We introduce a new interpretation and quantitative method for computerized diplopia test. By comparing this new method to the Hess screen test, we validate its applicability among 304 patients with ocular motor nerve palsy. This new method shows great assistant value as the Hess screen test in making accurate diagnosis and quantitative evaluation the severity of diplopia. Furthermore, it is more convenient and suitable for daily clinical use. PMID- 29181322 TI - Potential role of Muller cells in the pathogenesis of macropsia associated with epiretinal membrane: a hypothesis revisited. AB - Pathophysiological explanations for metamorphopsia associated with retinal pathologies generally focus on photoreceptor organization disruption. However, the retinal microarchitecture is complicated, and we hypothesize that other retinal cells may also be involved. Metamorphopsia has been widely studied in eyes with epiretinal membranes and we revisit the idea that Muller cell displacement causes retinal macropsia. A PubMed query and related article search for the macula ultrastructure under normal and pathological conditions revealed an enormous amount of information, particularly ultrahigh definition optical coherence tomography and other retinal imaging modality studies. Findings of these imaging studies support our hypothesis that Muller cells, and not cone photoreceptors, are primarily responsible for macropsia in eyes with epiretinal membranes. More specifically, we conclude that displacement of Muller cell endfeet, and not photoreceptor cones, is a more likely the explanation for retinal macropsia associated with epiretinal membranes. PMID- 29181324 TI - The prevalence of uncorrected refractive error in urban, suburban, exurban and rural primary school children in Indonesian population. AB - Uncorrected refractive error (URE) is a major health problem among school children. This study was aimed to determine the frequency and patterns of URE across 4 gradients of residential densities (urban, exurban, suburban and rural). This was a cross-sectional study of school children from 3 districts in Yogyakarta and 1 district near Yogyakarta, Indonesia. The information regarding age, sex, school and school grader were recorded. The Snellen's chart was used to measure the visual acuity and to perform the subjective refraction. The district was then divided into urban, suburban, exurban and rural area based on their location and population. In total, 410 school children were included in the analyses (urban=79, exurban=73, suburban=160 and rural=98 school children). Urban school children revealed the worst visual acuity (P<0.001) and it was significant when compared with exurban and rural. The proportion of URE among urban, suburban, exurban and rural area were 10.1%, 12.3%, 3.8%, and 1%, respectively, and it was significant when compared to the proportion of ametropia and corrected refractive error across residential densities (P=0.003). The risk of URE development in urban, suburban, exurban, and rural were 2.218 (95%CI: 0.914 5.385), 3.019 (95%CI: 1.266-7.197), 0.502 (95%CI: 0.195-1.293), and 0.130 (95%CI:0.017-0.972), respectively. Urban school children showed the worst visual acuity. The school children in urban and suburban residential area had 2 and 3 times higher risk of developing the URE.

AB - Adaptive optics scanning laser ophthalmoscopy (AO-SLO) has been a promising technique in funds imaging with growing popularity. This review firstly gives a brief history of adaptive optics (AO) and AO-SLO. Then it compares AO-SLO with conventional imaging methods (fundus fluorescein angiography, fundus autofluorescence, indocyanine green angiography and optical coherence tomography) and other AO techniques (adaptive optics flood-illumination ophthalmoscopy and adaptive optics optical coherence tomography). Furthermore, an update of current research situation in AO-SLO is made based on different fundus structures as photoreceptors (cones and rods), fundus vessels, retinal pigment epithelium layer, retinal nerve fiber layer, ganglion cell layer and lamina cribrosa. Finally, this review indicates possible research directions of AO-SLO in future. PMID- 29181325 TI - The use of choline in association with the Bangerter filters for the treatment of amblyopia. AB - The study investigated the effects of choline combined with Bangerter filter in the treatment of amblyopia. All amblyopic subjects used a Bangerter filter on the corrective spectacle lens (1d over the left eye, 1d over the right eye). Choline was then administered orally to 39 patients once daily, five days per week for the entire study period. Subjects treated with the Bangerter filter showed a mean visual acuity of 0.27 logMAR; at 12mo of treatment, the mean visual acuity reached 0.09 logMAR. Patients treated with the Bangerter filter and citicoline showed a mean visual acuity of 0.35 logMAR; at 12mo of treatment, the mean visual acuity reached 0.01 logMAR. No significant changes in the angle of deviation were observed in both groups. Subjects in both forms of amblyopia therapies demonstrated an increase in visual acuity. However, these effects were markedly enhanced when coupled with the administration of choline. Findings suggest that the effects are particularly relevant in the more severe amblyopic cases.

PMID- 29181330 TI - Evaluation of Admission Indications, Clinical Characteristics and Outcomes of Obstetric Patients Admitted to the Intensive Care Unit of a Teaching Hospital Center: A Five-Year Retrospective Review. AB - Background: Care of obstetric patients has always been a challenge for critical care physicians, because in addition to their complex pregnancy-related disease, fetal viability is considered. Objectives: The aim of this study was to review the admission indications, clinical characteristics and outcomes of obstetric patients, admitted to the intensive care unit of Alzzahra teaching hospital affiliated to Guilan University of Medical Sciences, Rasht, Iran. Methods: This retrospective cohort study was conducted on pregnant /post-partum (up to 6 weeks) patients admitted to the ICU over a 5-year period from April 2009 to April, 2014. Results: Data from 1019 subjects were analyzed. Overall, 90.1% of the patients were admitted in the postpartum period. The most common indications for admission were pregnancy related hypertensive disorders (27.5%) and obstetric hemorrhage (13.5%). Epilepsy (5.4%) and cardiac disease (5.2%) were the most common non obstetric indications. Conclusions: Pregnancy-related hypertensive disorders and obstetric hemorrhage were the main reasons for admission, and epilepsy and cardiac disease were the most common non-obstetric indications. Efforts must be concentrated on increasing antenatal care. PMID- 29181331 TI - Effect of Intravenous Acetaminophen on Postoperative Pain in Vitrectomy: A Randomized, Double-Blind, Clinical Trial. AB - Background: Nowadays, pain, nausea, and vomiting are regarded as important complications of anesthesia and surgery. The current study aimed at assessing the effect of preemptive intravenous acetaminophen on control of pain, nausea, vomiting, shivering, and drowsiness following the general anesthesia for retina and/or vitrectomy surgeries. Methods: In a randomized, double-blind, clinical trial, 83 candidates for retina or vitrectomy eye surgery under general anesthesia were distributed into 3 groups: A) 41 patients in the control group who received 100 mL of normal saline just before the surgery and 100 mL of normal saline 20 minutes before the end of surgery; B) 21 patients in the preemptive group who received acetaminophen 15 mg/kg in 100 mL normal saline just before the surgery and 100 mL normal saline 20 minutes before the end of surgery; C) 21 patients in the preventive group who received 100 mL normal saline just before the surgery and acetaminophen 15 mg/kg in 100 mL normal saline 20 minutes before the end of surgery. Pain, nausea, vomiting, and shivering were assessed at the recovery and 2, 4, and 24 hours after the operation. Anesthesia emergence situation was assessed after arrival in the recovery room by the Richmond agitation-sedation scale (RASS) questionnaire. Blood pressure and heart rate were recorded before anesthesia induction, just after intubation, before extubation, and on discharge from the recovery room. Results: Total intraoperative fentanyl, duration of operation, and duration of anesthesia were not different among the studied groups. Vital signs were not statistically different among the groups at before anesthesia induction, just after intubation, before extubation, and on discharge from the recovery room. Thirty-three patients in the control group (87.8%), 11 in preemptive (52.4%), and 14 in preventive groups (66.7%) needed acetaminophen in the first 24 hours after the surgery (P value = 0.008). Pain scores measured by visual rating scale (VRS) was lower in the preemptive and preventive groups, compared with those of the control group, in the recovery (P value = 0.006), 2 hours after the surgery (P value = 0.008), and 4 hours after the surgery (P value = 0.012), but not in 24 hours after the operation (P value = 0.1). Conclusions: Intravenous acetaminophen administered as preemptive or preventive medication was effective and safe to control acute postoperative pain and analgesic request after the vitrectomy eye surgery. PMID- 29181332 TI - Intravenous Midazolam as More Effective Than Propofol for Preventing Pruritus After Intrathecal Sufentanil in Surgical Patients: A Randomized Blinded Trial. AB - Background: Pruritus is a troublesome side effect of intrathecal opioids. Midazolam can reinforce GABA-mediated inhibition of the medullary dorsal horn neurons, and thus theoretically has potential to suppress opioid-induced pruritus. Objectives: This prospective double-blinded randomized trial aimed at comparing the effects of propofol, midazolam, and a combination of the two on the prevention of pruritus induced by intrathecal sufentanil. Methods: Eighty-four patients undergoing spinal anesthesia with 3 mL hyperbaric bupivacaine 0.5% and 5 MUg sufentanil (1 mL) were randomly allocated to one of the three study groups: Group 1, who were administered 20 mg intravenous (IV) propofol bolus, then 50 MUg/kg/min IV infusion; Group 2, who were administered 0.03 mg/kg IV midazolam bolus, then 0.02 mg/kg/h IV infusion; and Group 3, who were administered 10 mg IV propofol and 0.015 mg/kg IV midazolam bolus, then 25 MUg/kg/min propofol and 0.01 mg/kg/h midazolam IV infusion. The incidence rates and severity of pruritus were assessed intraoperatively and postoperatively for 24 hours. Results: The Ramsay Sedation Score was highest for the propofol group throughout the duration of the anesthetic process. Overall, 17 patients in the propofol group (60.7%), eight patients in the midazolam group (28.6%), and nine patients in the propofol midazolam group (32.1%) developed pruritus (P = 0.027). Intraoperative pruritus was observed in seven patients in the propofol group (25%), two patients in the midazolam group (7.1%), and five patients in the midazolam-propofol group (17.9%) (P = 0.196). Postoperative pruritus developed in 12 patients in the propofol group (42.9%), six patients in the midazolam group (21.4%), and four patients in the midazolam-propofol group (14.3%) (P = 0.041). There was no significant difference between the groups with respect to the severity of pruritus (P > 0.05). Conclusions: This study showed that in comparison with propofol, the administration of 0.03 mg/kg IV midazolam bolus followed by 0.02 mg/kg/h could be more effective in the prevention of intrathecal sufentanil-induced pruritus without increasing sedation and other side effects. PMID- 29181333 TI - Developing Cervical Hematoma Following Jaw Thrust Maneuver Triggered Diagnosis of Neurofibromatosis: A Case Report and Brief Literature Review. AB - A 25-year-old man underwent an excision of a thigh mass under general anesthesia without any complication. After the operation, he developed oxygen desaturation requiring a jaw thrust maneuver. A rapidly expanding hematoma on the right side of the neck was formed shortly after the application of the maneuver. The patient was returned to the operation room for a neck exploration. Damage to the facial artery and vein was noted. Further evaluations confirmed the diagnosis of Neurofibromatosis type 1 (NF-1). It is recommended that considering the probable risk of arising hematoma in NF-1 patients, application of jaw thrust maneuver should be performed meticulously.

PMID- 29181335 TI - Perceived Workplace Stress Is Associated with an Increased Risk of Prostate Cancer before Age 65. AB - Background: Evidence is lacking regarding the potential role of chronic psychological stress on cancer incidence. The workplace is reported to be the main source of stress among Canadian men. We examined the association between perceived lifetime workplace stress and prostate cancer (PCa) risk in a large case-control study. Methods: Cases were 1,933 men, aged <= 75 years, newly diagnosed with PCa in 2005-2009 across hospitals in Montreal, Canada. Concurrently, 1994 population controls frequency-matched on age were randomly selected from the electoral list based on cases' residential districts. Detailed lifestyle and work histories (including perceived stress, from any type of work stressor, for each job held) were collected during in-person interviews. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) for the association between work-related stress and PCa risk in multivariate analyses. Results: Over the lifetime, 58% of subjects reported at least one job as stressful. Occupations described as stressful were most often among white collar workers. Perceived workplace stress duration was associated with a higher risk of PCa (OR = 1.12, 95% CI:1.04-1.20 per 10-year increase) among men younger than 65 years, but not among older men. Associations were similar irrespective of PCa aggressiveness. Frequent or recent screening for PCa, age at first exposure and time since exposure to work-related stress, and socioeconomic and lifestyle factors, had little influence on risk estimates. Conclusion: Findings are in line with an association between reporting prolonged workplace stress and an increase in risk of PCa before age 65. PMID- 29181334 TI - Inflammatory Signaling Pathways in Preleukemic and Leukemic Stem Cells. AB - Hematopoietic stem cells (HSCs) are a rare subset of bone marrow cells that usually exist in a quiescent state, only entering the cell cycle to replenish the blood compartment, thereby limiting the potential for errors in replication. Inflammatory signals that are released in response to environmental stressors, such as infection, trigger active cycling of HSCs. These inflammatory signals can also directly induce HSCs to release cytokines into the bone marrow environment, promoting myeloid differentiation. After stress myelopoiesis is triggered, HSCs require intracellular signaling programs to deactivate this response and return to steady state. Prolonged or excessive exposure to inflammatory cytokines, such as in prolonged infection or in chronic rheumatologic conditions, can lead to continued HSC cycling and eventual HSC loss. This promotes bone marrow failure, and can precipitate preleukemic states or leukemia through the acquisition of genetic and epigenetic changes in HSCs. This can occur through the initiation of clonal hematopoiesis, followed by the emergence preleukemic stem cells (pre LSCs). In this review, we describe the roles of multiple inflammatory signaling pathways in the generation of pre-LSCs and in progression to myelodysplastic syndrome (MDS), myeloproliferative neoplasms, and acute myeloid leukemia (AML). In AML, activation of some inflammatory signaling pathways can promote the cycling and differentiation of LSCs, and this can be exploited therapeutically. We also discuss the therapeutic potential of modulating inflammatory signaling for the treatment of myeloid malignancies. PMID- 29181337 TI - The Many-Faced Program of Epithelial-Mesenchymal Transition: A System Biology Based View. AB - System biology uses a range of experimental and statistical methods to dissect complex processes that results from alterations in biological models. Given the complexity of the epithelial-mesenchymal transition (EMT) program, system biology represents a promising approach to understanding its fine molecular regulation by the interpretation of high-throughput datasets. Herein, we review recent contributions of system biology applied to the field of EMT physiology and illustrate the importance of these approaches to model biological networks that are perturbed during the transition. Together, these results allowed the definition of an EMT signature across different tumor types, the identification of dysregulated processes and new modules of regulation, making possible to reveal the EMT molecular visage underneath. PMID- 29181338 TI - Interleukin-35 Suppresses Antiviral Immune Response in Chronic Hepatitis B Virus Infection. AB - The mechanisms of hepatitis B virus (HBV) persistent infection are not completely understood. Interleukin (IL)-35, which is a newly identified cytokine belongs to IL-12 family, has been demonstrated to induce immunotolerance. Thus, the aim of current study was to investigate the role of IL-35 during chronic HBV infection. A total of 61 patients with chronic HBV infection [37 chronic hepatitis B (CHB) and 24 asymptomatic HBV carriers (ASC)] and 20 healthy individuals were enrolled. IL-35 concentration as well as the modulatory function of IL-35 on CD4+CD25+CD127dim/- regulatory T cells (Tregs) and on HBV antigen-specific CD8+ T cells was investigated. IL-35 expression was significantly increased in both CHB and ASC, and was positively correlated with the levels of HBV DNA. Inhibition of viral replication induced the reduction in serum levels of IL-35. IL-35 stimulation led to inhibition of proinflammatory cytokine productions and elevation of apoptosis in peripheral blood mononuclear cells (PBMCs), but not in HepG2.2.15 cells. Moreover, IL-35 stimulation not only robustly inhibited cellular proliferation, but also up-regulated the production of IL-10 and IL-35 in a HBV antigen-specific and non-specific manner in Tregs/CD4+CD25- T cells coculture system, which indicated enhancement of suppressive function of Tregs. Furthermore, IL-35 also reduced both cytolytic activity (direct lysis of HepG2.2.15 cells) and noncytolytic function (IFN-gamma and TNF-alpha production) of HBV antigen-specific CD8+ T cells. The current data suggested that IL-35 contributed to maintain viral persistence by suppressing antiviral immune responses and reducing inflammatory responses in chronic HBV infection.

AB - Introduction: Odontoideum bone or the mobile odontoid process is one of the rarest malformations of the cervico-occipital hinge. It exposes to the atlo-axial instability and to the risk of bulbo-medullary compression threatening then the vital and functional prognosis. We report the case of a 16-year-old patient who was the victim of a raod accident resulting in acervical spine injury. Radiological investigation found an odontoideum bone malformation associated with C1C2 dislocation. Case Report: A 16-year-old patient with no medical history had a road accident. Clinical evaluation found an incomplete tetraplegia.The imaging has revealed an atlo-axoidal dislocation with aspinal cord compression. Furthermore, radiological exams relvealed an odentoideum bone. A transcranial traction by a Gardner stirrup was set for 15 days to obtain a progressive reduction of the displacement. A full neurological recovery (FB-FD) was obtained.The patient was then operated to stabilize the reduction. A C1-C2 posterior zygapophyseal arthrodesis was performed. An autograft harvested from the iliac crest was used. Complementary open reduction and fixation of the cervico-occipital hinge was made using lamellar hooks and compression rods. At the 18-month follow-up, the clinical examination found no neurological deficiency and the plain radiography showed a complete fusion of the arthrodesis. Conclusion: Odontoideum bone is a rare and potentially life-threatening malformation. It is most often asymptomatic but symptoms could occur any time after a benign trauma. The prognosis mainly depends on the precocity of the management. Preventive surgery is recommended byseveral authorsin case ofinstability. PMID- 29181342 TI - Early Loosening of Spinal Rod in a Case of Degenerative Grade 1 Spondylolisthesis treated with Unilateral Pedicle Screw Fixation and Transforaminal Cage for Interbody Fusion. AB - Introduction: Unilateral pedicle screw fixation and transforaminal cage for interbody fusion are well-established form of treatment for lumbar spondylolisthesis. It is cost effective and has shown to have a comparable outcome to bilateral pedicle screw fixation. We present a case of unilateral pedicle screw fixation and transforaminal cage for interbody fusion in a patient of Grade 1 Degenerative spondylolisthesis who had an early implant failure, and try to assess the possible events leading to it. Case Report: A 53-year-old female presented to our outpatient department with low back pain that had persisted for a few years. Plain radiographs revealed degenerative Meyerding Grade I spondylolisthesis at L5-S1. The patient underwent posterior decompression through left-sided laminotomy followed by pedicle screw fixation on the right side. Screws were inserted in the pedicle of L5-S1. An optimal hold of the screw in the left pedicle of L5 could not be achieved due to the poor quality of bone; hence, intraoperatively, the plan was revised from bilateral to unilateral pedicle screw fixation. Further, a transforaminal interbody cage was inserted. The patient started complaining of severe pain on the 8th post-operative day. X ray done on the next day revealed loosening of the rod from the L5 pedicle screw, with back out of the insert screw. The patient was subsequently posted for revision surgery. During the subsequent follow-up at 6 months, the patient has shown significant symptomatic improvement and has resumed her routine daily activities. Conclusion: Early rod loosening and migration are a rare phenomenon in lumbar pedicle screw fixation. Meticulous and precise pre-operative planning and surgical techniques may avert such complications. This case highlights the fact that though unilateral fixation is a reported treatment for listhesis, the proper case selection is needed. Conditions such as obesity and osteoporosis need to be considered, and preferably bilateral fixation should be done in such cases. PMID- 29181344 TI - Successful Two-step Correction for Severe Genu Valgum in Ellis-van Creveld Syndrome: A Case Report. AB - Introduction: Ellis-van Creveld syndrome (EVC) is a very rare genetic disorder involving a severe, relentlessly progressive genu valgum deformity of the knee and it is usually difficult to correct all of the deformities by elevation of the depressed lateral tibial plateau alone. We are reporting one such case treated using two-step operative technique (first, gradual correction using Taylor spatial frame (TSF) and second, tibia elevation through intra-articular osteotomy). Case Report: We report a case of 10-year-old female with severe genu valgum in EVC using two-step operative technique. First, performing soft tissue release and gradual correction using a TSF. Second, tibia elevation through intra articular osteotomy resulted in improved joint congruity. At final follow-up, the patient has a good functional result and the Mikulicz line proceeded physiologically to the joint center. Conclusion: This two-step technique allowed for the correction of the joint architecture and associated complications are minimal. For severe genu valgum in EVC, joint congruity is improved by the elevation of the anterolateral aspect of the tibia through intra-articular osteotomy. Performing soft tissue release followed by gradual correction allows for correction of the valgus and external rotation deformities without causing neuroparalysis. PMID- 29181343 TI - Retained Drain after Anterior Cruciate Ligament Surgery : A Silent Threat to an Athlete's Career: A Case Report. AB - Introduction: Breaking of surgical drain during the removal and retention of broken drain fragment is an avoidable complication. Such a complication brings disrepute to the operating team and causes psychological as well as further surgical trauma to the patient as a return to the operating room is required many a times to remove the retained drain fragment. Case Report: We report a case of an undetected retained drain fragment inside the knee joint of a 24-year-old male international kabaddi player, who remained asymptomatic for 5 months, when the residual drain fragment was removed arthroscopically. No such case has been reported earlier in the literature after arthroscopic surgery. Conclusion: Retained drain fragment after arthroscopic surgery can stay silent for months. Hence, a high index of suspicion should be maintained by surgeons to detect such a complication at the earliest. We suggest that every arthroscopic surgeon should follow a standard protocol while inserting and removing the drain to avoid this mistake. PMID- 29181345 TI - Intrapleural Penetration of a Clavicle Fracture: An Indication for Operative Fixation. AB - Introduction: Clavicle fractures are common injuries treated by orthopedic surgeons, with most injuries managed nonoperatively. Operative fixation of clavicle fractures is indicated in specific clinical scenarios such as open injuries, ipsilateral shoulder trauma, or fractures with associated neurovasculature compromise. Operative fixation is not widely accepted for closed injuries and is typically reserved for instances of failed closed treatment with resultant nonunion or delayed union. Among the complications associated with clavicle fractures, pneumothorax has not been commonly reported. We report a case of a severely displaced clavicle fracture requiring operative repair through plate fixation to achieve union of the fracture as well as resolve the pneumothorax. Case Report: A 22-year-old intoxicated male with no past medical history was admitted to the trauma bay in stable condition after being involved in a motor vehicle accident. On the primary survey, the patient was noted to be tachypneic with decreased breath sounds over his right hemithorax. Radiographic studies of his chest demonstrated a right proximal third clavicle fracture with inferior displacement with associated partial pneumothorax; the patient was also noted to have a right femoral shaft fracture. Neurovascular examinations of his extremities were normal. A chest thoracostomy tube was inserted and placed under suction. Computerized tomography studies later revealed that the fractured clavicle had penetrated the pleura and caused the partial lung collapse. The patient was initially placed in a sling and underwent intramedullary nailing of his femur on the day of presentation. Given the severe displacement of his clavicle fracture into the lung tissue resulting in pneumothorax, there was significant concern for nonunion and lack of resolution of the pneumothorax. 2 days after stabilization of his right femur fracture, the patient underwent open reduction with internal fixation of his right clavicle. Follow-up radiographs showed a healed clavicle fracture and resolved pneumothorax. Conclusion: Closed clavicle fractures typically heal uneventfully. Low energy, minimally displaced clavicle fractures can be managed nonoperatively, but high energy, significantly displaced injuries may require operative repair. Specifically, if these injuries result in pneumothorax, physicians shoulder consider operative repair for both treatment of the bony defect as well resulting pneumothorax. PMID- 29181346 TI - Phalangeal Fracture During Attempted Dupuytrens Release Following Clostridial Collagenase Injection: Case Report. AB - Introduction: Dupuytren's disease can be a challenging condition for both patients and surgeons. Injectable collagen clostridium histolyticum was approved for clinical use by the Food and Drug Administration in 2010. A number of side effects have been described. In this case report, we present a complication of a proximal phalanx fracture which occurred during attempted release post injection. To the best of our knowledge, this is the first reported case of this particular complication. Case Report: The patient is an 80-year-old right-hand dominant retired male with bilateral hand contractures and palmar fibromatosis. His medical history is notable for Type II diabetes mellitus and metastatic thyroid cancer. The patient underwent Xiaflex injection of the left small finger and returned 4 days later for planned release. An appreciable release of the contracture was noted; however, there was a concern for plastic deformation of the proximal phalanx as a result of the manipulation. X-rays confirmed the fracture and apex volar angulation at the base of the proximal phalanx. The fracture appeared amenable to non-operative treatment. The patient has been followed closely and has had no pain or tenderness at the fracture site and minimal swelling. X-rays at 1 week and 1 month showed maintained alignment and signs of consolidation at the fracture site. The patient is currently 4-month post-fracture, and no further intervention has been pursued. Conclusions: This report represents an additional potential complication associated with the use of Xiaflex. We recommend judicious use in elderly patients with severe contractures and/or multiple comorbidities. It is important to appreciate the possibility of this complication at the time of release. PMID- 29181347 TI - Pelvic Hydatid Disease: A Case Report and Review of Literature. AB - Introduction: Cystic echinococcosis of the bone is rare and difficult to treat due to frequent recurrences, especially in certain locations such as ilium and hip, where radical surgery is difficult to achieve. Case Report: We present a case of a 35-year-old female of the Indian subcontinent who had complaints of pain in left hip and limp since 1 year. The first clinical and radiological diagnosis was tuberculosis of the hip. However, higher imaging modalities revealed the diagnosis of hydatid disease of hip. The patient underwent surgical debridement and anti-helminthic chemotherapy. At 3-year follow-up, the patient was disease- free. Conclusion: Hydatid disease of the hip and pelvis, although rare must be kept in the differential diagnosis of pathologies of hip-like tuberculosis. Debridement and excision of hip joint give good functional outcome, while also minimizing morbidities that are usually associated the use of custom made prosthesis or complex arthroplasty. PMID- 29181348 TI - Focal Periphyseal Edema Zone on Magnetic Resonance Imaging in the Greater Trochanter Apophysis: A Case Report. AB - Introduction: Magnetic resonance imaging (MRI) has been used to identify focal bone marrow edema or a focal periphyseal edema (FOPE) zone, in the closing growth plates of adolescent knees. Case Report: In the current case, an 11-year-old boy reported pain in his left hip. He had been participating in gymnastic classes at school, but otherwise, he was not an active athlete. Based on MRI findings, he was diagnosed with a FOPE zone in his greater trochanteric apophysis. Discontinuity of the cartilaginous growth plate at the FOPE zone was indicative of osseous continuity between the metaphysis and apophysis. Conclusion: This case suggested that a FOPE zone can occur in a non-weight bearing growth plate and through a tethering mechanism at the initial ossification site during skeletal growth plate maturation. PMID- 29181349 TI - Unstable Pediatric Femur Fractures: Combined Intramedullary Flexible Nails and External Fixation. AB - Introduction: The treatment of pediatric femur fractures continues to evolve. In the past, many of these fractures required prolonged hospitalization in traction. More recently, flexible elastic nails have gained popularity. However, length unstable and comminuted fractures can present some unique challenges. To avoid common complications of elastic nailing in the setting of unstable fractures we describe a technique of augmenting this treatment with external fixation for cases requiring additional rotational or longitudinal stability. Case Report: A series of two patients are described who underwent intramedullary flexible nails and external fixation for a closed unstable midshaft femur fracture: An 8-year old male that sustained a left periprosthetic femur fracture after a fall on his scooter, and a 5-year-old female that sustained a right femur fracture after a fall from a wet decking. Both patients had their external fixator removed after 4 weeks and achieved radiographic and clinical fracture union at 8-week postoperatively. Conclusion: Treatment with elastic nails and external fixator for unstable pediatric femur fractures is a minimally invasive technique that safely provides fracture stability.

AB - Introduction: Tibial plateau fractures are complex injuries in the elderly population. When traditional methods of fixation are not suitable, an alternative method needs to be chosen for a favorable outcome. We demonstrate a previously undescribed treatment for displaced tibial plateau fractures in the very elderly with poor soft-tissue integrity. Case Report: A 90-year-old woman suffered an open, Gustilo Grade IIIA, displaced fracture of the tibial plateau. An intramedullary knee arthrodesis, the femoral-tibial nail was used to temporarily stabilize her fracture. She was able to weight bear immediately postfixation. Conclusion: A long femoral-tibial nail allows favorable fracture and soft tissue healing, ease of nursing and immediate full weight-bearing. It shows good promise and should be considered as a management option when traditional methods are not applicable in select patients.

AB - Introduction: Cerclage wiring has been used in the past for osteosynthesis of femoral fractures. However, the technique went into disrepute as extensive soft tissue dissection, and periosteal stripping increased the risk of bone necrosis and delayed union. Advent of new instrumentation and minimally invasive technique has significantly reduced these complications. In spite of the limited indications for its application, reduction and stabilization with cerclage wiring can supplement osteosynthesis especially in spiral or oblique fracture morphology or those with a butterfly fragment instead of interfragmentary screw fixation. This series attempts to describe the feasibility and evaluate outcomes of cerclage wiring as an adjunct to osteosynthesis and reestablish its place in reduction and fixation of femur fractures. Case Report: This is a retrospective case series of patients (January 2011 to October 2015) in whom cerclage wiring was used as an adjunct to osteosynthesis of primary and periprosthetic fractures of femur. Patient demographics, number of wires used, implant used for osteosynthesis, number of days to union, union rate and complications were recorded and analyzed. The patients were followed up for a minimum of 6 months. 11 patients (7 female and 4 male) with a mean age of 67.10 +/- 21.64 years were studied. The number of patients with intertrochanteric, subtrochanteric, diaphyseal, and periprosthetic fractures of the femur was two, five, one, and three, respectively. Internal fixation was done with plates in six and cephalomedullary nails in five patients. Mean total number of wires used was 2.10 +/- 0.70. Mean duration of follow-up was 15.91 +/- 10.03 months. Union was achieved in all cases with a mean duration of 86.63 +/- 22.44 days. There were no complications in our study. Conclusion: Cerclage wiring technique helps to achieve stable reduction of femoral fractures which can then be supplemented with a nail or a plate. The minimally invasive technique and instrumentation offer the advantage of minimal soft tissue dissection, and the procedure is associated with excellent outcomes without any major complications. PMID- 29181352 TI - A Case Report of Dual Incision Technique for Total Femur Arthroplasty as a Salvage Procedure in Infected Non-Unions. AB - Introduction: Total femur arthroplasty (TFA) is a rare salvage limb procedure which serves as an effective alternative to limb amputation. Most commonly, it is indicated for oncologic orthopedic cases, and very few cases of a purely traumatic history for TFA have been documented. The decision to perform this complex procedure involves paying careful attention to reconstructive needs and functional expectations of the patient. Alternatives to this procedure are quite detrimental and include hip disarticulation and above-the-knee amputation. Case Report: A 66-year-old woman with a history of hypertension, and parkinsonism was brought into the outpatient department of a tertiary care hospital. She has undergone a procedure for proximal femur nailing on her left hip in 2013 due to a trauma-related fracture. However, after the development of a series of complications, she underwent revision surgery on her left hip 6 times by different surgeons. This included surgeries for implant removal and fixation of a custom-made bipolar hemi-replacement hip, followed by a cemented bipolar hip hemi replacement with plating and cerclage wires followed by infection, the treatment of which entailed implant removal and placement of an antibiotic cement. This was followed by a long stem constrained cemented total hip arthroplasty which also failed. The surgeon then made the decision to perform a TFA. 12-month follow-up post-operatively showed neither peri-prosthetic infection or inflammation nor any leg length discrepancy. The functional outcome on lower extremity function scale showed improvement from 0 pre-operatively to 31 at 12-month follow- up. Conclusion: TFA serves as a viable technique for salvage of the lower extremity in cases of infected non-unions. However, a thorough evaluation of the particular case in the hand should be made before reaching a conclusion. PMID- 29181353 TI - Pyomyositis of Gluteus medius: A case report and review of the literature. AB - Introduction: We present a case of 12 year old boy presented with right hip pain, fever and antalgic gait. Inflammatory markers were raised at presentation. The pelvic radiograph and ultra sound scan of right hip joint did not detect any abnormality. The Magnetic Resonance Imaging (MRI) scans revealed inflammatory oedema in the right gluteus medius muscle. He was treated with intravenous Flucloxacillin for 10 days and later 6 weeks of oral Flucloxacillin. At the 6 weeks follow up patient was asymptomatic with normal gait. MRI at 6 weeks did not show any fluid collection in gluteus medius. Conclusion: Pyomyositis is rare in temperate countries. It must be considered as one of the differential diagnosis in a child presenting with hip pain, fever and raised inflammatory markers. PMID- 29181354 TI - Central Chest Pain - An Atypical First Presentation. AB - Introduction: The diagnosis of thoracic spondylodiscitis is challenging, given that it is a rare entity in itself and when unusual symptoms such as central chest pain predominate on presentation, it may pose a serious diagnostic challenge. Case Report: A 54-year-old patient presented to accident and emergency with central chest pain and elevated inflammatory markers (C- reactive protein [CRP]: 21 mg/L). Following exclusion of life-threatening cardiac causes, he was discharged home with analgesia and no formal diagnosis. Over the course of the subsequent 6 weeks, he presented to his general practitioner on two different dates with worsening chest pain alongside a new symptom of back pain and progressively rising inflammatory markers. At 6 weeks, he presented back to the emergency department with clinical signs of sepsis, mid-thoracic tenderness with weakness and altered sensation to his legs. The CRP was raised at 297 mg/L. In view of these symptoms, a contrast magnetic resonance imaging scan was performed which revealed destruction of the sixth and seventh disc space with high signal intensity on T2 and short tau inversion recovery images in T6 and T7. Blood cultures were shown to have grown Staphylococcus aureus, and the patient was subsequently treated with combined intravenous antibiotics (flucloxacillin) and oral antibiotics (rifampicin) for 15 weeks resulting in complete resolution of his symptoms. Conclusion: Our case report highlights the need for a high index of suspicion of spondylodiscitis in patients presenting with central chest pain, unresolving back pain and elevated inflammatory markers especially in the absence of any other formal diagnosis. PMID- 29181355 TI - Group B Streptococcal Prosthetic Knee Joint Infection Linked to the Consumption of Raw Fish. AB - Introduction: Group B Streptococcal (GBS) prosthetic joint infections (PJI) are rare, accounting for only 4.6-6% of primary and revision total knee replacements (TKRs). In 2015, there was an outbreak of GBS infections in Singapore with an association confirmed between consumption of Chinese-style raw fish dishes (snakehead fish, Asian bighead carp) and GBS infection, Type III GBS ST283 strain, affecting more than 200 patients in Singapore. This outbreak is the largest of its kind in the world and also the first time that foodborne transmission of GBS has been proven. We present the first reported case in the literature of a confirmed PJI in a TKR related to foodborne transmission of GBS through consumption of raw fish (Snakehead fish). Case Report: Our patient is a 66-year-old Chinese female admitted with a 24-h history of acute right knee pain and swelling with associated fever in the context of consuming raw fish porridge 3 days before the onset of her symptoms. She had a TKR performed in the same knee 7 years before this presentation. Her GBS PJI was confirmed on both blood and intraoperative tissue/fluid cultures during the outbreak of GBS infections in Singapore. This was managed with debridement, polyethylene liner change, retention of metal prosthesis, and culture-directed antibiotics with good outcomes. Conclusion: Snakehead fish is a popular dish in the Asian community as a traditional remedy to promote wound healing after surgery. Our paper highlights the link between raw fish consumption and invasive GBS causing PJIs. This can occur in healthy adults, even in the absence of gastrointestinal symptoms, despite being a foodborne transmission. Our paper also highlights that GBS PJIs can be managed with debridement, antibiotic therapy, and implant retention with good outcomes in the setting of acute hematogenous infection. We recommend the inclusion of raw fish consumption on history taking in the workup of suspected PJIs and counseling patients preoperatively on the risk of GBS PJIs with the consumption of raw fish dishes (snakehead fish and Asian bighead carp) to mitigate unnecessary PJI risk.

AB - Introduction: Old neglected posterior type of elbow dislocations is not very common and generally requires open reduction. It was usually treated with open reduction and K-wire stabilization. We did a newer method in which in addition cruciate type ligament reconstruction; we have reconstructed lateral ulnar collateral ligament (LUCL) and UCL (medial collateral ligament) using semitendinosus graft. This allowed extra stability and early mobilization of the elbow joint. Authors report 3-month-old neglected posterior type of elbow dislocation without any fracture. Case Report: A 42-year-old male presented with pain and tenderness with deformity of the left elbow joint and inability to move the elbow joint after he fell down since 3 months. There was no neurovascular deficit. Radiological examination confirmed posterior dislocation of elbow joint without any fracture. The patient is managed by open reduction and cruciate ligament reconstruction of elbow joint using autologous semitendinosus graft. Conclusion: Open reduction with cruciate ligament reconstruction provides excellent stability for early mobilization of old neglected elbow dislocation. PMID- 29181357 TI - Aspergillus Osteomyelitis of the Ribs in Immunocompetent Hosts: Report of Two Rare Cases. AB - Introduction: Osteomyelitis is rarely caused by fungi, most common among them being Candida. Aspergillus is a rare cause of fungal osteomyelitis mimics tuberculous osteomyelitis. Aspergillus osteomyelitis (AO) of the ribs is relatively uncommon, with an incidence rate of only 9% among all reported cases of AO. With mortality rates of almost 25%, AO is on the rise attributed to increasing numbers of immunocompromised individuals. There are very few case reports of AO of ribs in immunocompetent individuals. We report two such cases. Case Report: Case 1: A 51-year-old male developed spontaneous chest pain along right costal margin with a low-grade fever. High-resolution computed tomography chest revealed osteomyelitis of anterolateral chest wall. He did not improve with empirical antitubercular therapy, and subsequent debridement showed polymicrobial pyogenic infection which was managed with appropriate antibiotics elsewhere. Samples were not sent for fungal culture. He presented to us 3 months later, and surgical debridement showed growth of Aspergillus flavus which was managed with oral voriconazole. The lesion healed with no recurrence at 24-month follow-up. Case 2: A 40-year-old male presented to our institute with left-sided chest pain, low-grade fever, and loss of appetite. There was a history of injury with a sharp piece of wood 2 years earlier. Magnetic resonance imaging defined the lesion which was biopsied under ultrasound guidance. Cultures grew A. flavus which was treated with oral voriconazole. He had complete clinical improvement at 16-month follow-up. Conclusion: More number of AO cases are being reported in immunocompetent individuals. Variability in clinical picture, rarity, misdiagnosis, empirical therapy, and failure to send deep tissue samples for fungal cultures are some of the reasons for the high mortality rates. It is paramount in today's scenario of atypical presentations, to obtain deep tissue for all cultures including fungal culture and histopathology, either surgically or under image guidance to achieve good clinical outcomes. Our study highlights that following the strict protocol of obtaining tissue for fungal culture, systemic antifungal therapy, and surgical debridement where necessary can help to diagnose and treat this rare pathology and ensure the good clinical outcome. PMID- 29181358 TI - A Case Report: Upper Thoracic Chance Fracture with Monoplegia... An Unusual Presentation! AB - Introduction: Chance fractures, the horizontal splitting vertebral fractures caused by flexion distraction mechanism, are inherently unstable fractures. These fractures can land up with significant visceral injuries. There are most commonly seen at thoracolumbar junction or in lumbar spine due to their high mobility. These fractures are extremely rare in the thoracic spine due to the rigidity of thoracic spine rendered by attachment of ribs. Furthermore, the level of injury makes neurological complications even graver. Case Report: We present a case of a road traffic accident with right lower limb monoplegia. On careful examination, a thin transverse fracture line was noticed in D5 vertebral body, and magnetic resonance imaging revealed posterior ligamentous disruption extending in line with the transverse fracture line in D5 vertebral body which confirmed the diagnosis of a Chance fracture. Fracture was stabilized by pedicle screw fixation from D4 to D7 level, and decompression was done at D5 level. By the end of 7 months, patient regained Grade 4 power in the right hip and knee joints, with Grade 5 power in the right ankle and great toe. Conclusion: Chance fractures in thoracic region are extremely rare. A clinician should have a high index of suspicion as these fractures can be notorious when it comes to presentation on plain X-ray. These being inherently unstable fractures, posterior instrumented stabilization with decompression in patients with neurodeficit gives good results. PMID- 29181359 TI - Articular Reconstruction using Subchondral Cementation and Threaded Kirschner wires in Giant Cell Tumor: A Novel Technique. AB - Introduction: Giant Cell Tumor(GCT) is one of an infrequently encountered tumor by orthopaedic surgeons in clinical practice. It is described as 'locally malignant' tumor found in epimetaphyseal region of long bones, peculiarly around knee. We present a case of a solitary, benign Campanacci Grade 2 GCT in right lateral femoral condyle in 38 year old female and our treatment. Case Report: A 38 year old female presented to our outpatient department with chief complaint of constant, moderate pain in right knee increasing in duration since 3 months. No history of precedent trauma. Radiological imaging with radiographs showed suspicious lytic lesion in lateral femoral condyle. MRI scan was done.On biopsy, histopathological evaluation showed presence of characteristic multinucleated giant- cells. After confirmation, tumor en bloc resection was done, followed by chemical cauterization with 5 % phenol. Articular margins were realigned under direct vision and fixed with 1.8 mm threaded K wires. PMMA cementing in bone defect was done after achieving adequate hemostasis. At two years follow-up, patient had good result in terms of pain, knee range of motion and weight bearing. Conclusion: Combination treatment of radical curettage, phenol irrigation, electrocautery and cementation is effective in preventing local recurrence. This can replace en bloc resection with a wide margin. Using subchondral threaded Kirschner wires to maintain articular margins is cheap alternative to costly implants in economically underprivileged patients. PMID- 29181360 TI - Tension Band Wiring Is As Effective As A Compression Screw In A Neglected, Medial Maleolus Non-Union: A Case-Based Discussion & Literature Review. AB - Introduction: Isolated, neglected medial malleolus nonunion cases are a rare entity in orthopedic literature. All studies (except one) have described the use of compression screws (with or without plates) for medial malleolar nonunion management. In acute fractures, tension band wiring (TBW) has shown excellent results both in biomechanical and in clinical studies. On the contrary, it has seldom been used in nonunion or in neglected cases. Case Report: We describe a 6 month-old neglected medial malleolus gap nonunion case who presented with progressive pain and limp. TBW with a monoblock, inlay, tricortical, and iliac crest bone graft for the defect was performed. The fracture united within 12 weeks and patient went back to his normal work routine; on the latest follow-up at 3 years, the patient was asymptomatic with no clinicoradiologic signs of secondary osteoarthritis of the ankle joint. Conclusion: TBW may be better than screw fixation in the management of medial malleolus nonunion as it is technically straightforward and cost-effective, can provide equal or more compression than a screw; it does not damage the sandwiched inlay bone graft, and the amount of compression is surgeon-controlled. It is also more suitable for fractures with small distal fragments and/or osteoporosis. PMID- 29181361 TI - Insufficiency Fractures at Unusual Sites: A Case Series. AB - Introduction: Insufficiency fractures (IFs) are a subtype of stress fractures commonly associated with osteoporosis and Vitamin D deficiency. These nontraumatic fractures often occur in the pelvis and spine, but the involvement of other unusual sites is also not very uncommon. Plain radiographs and magnetic resonance imaging scan are the most commonly used imaging modalities for the diagnosis of IF. Case Report: We are presenting a series of five cases of IFs at unusual sites, along with a detailed literature review on this individual. A 50 year-old male patient with chronic kidney disease presented with both femoral neck and right lesser trochanter IF which was managed with cannulated screws. A 53-year-old male patient on steroid presented with sternum IF. A 26-year-old male patient presented with Vitamin D deficiency and accessory navicular IF. A 60-year old female on bisphosphonate therapy came with bilateral femoral shaft fracture. All these three patients were managed conservatively. Another 62-year-old male patient with rheumatoid arthritis presented with sacrum IF which was managed with cannulated screw fixation. Conclusion: IFs are a subtype of stress fractures commonly associated with osteoporosis and Vitamin D deficiency. A good clinical examination along with proper radiological investigation facilitates early diagnosis of IF in the osteoporotic bone. An early diagnosis helps in deciding the definitive course of treatment and to obtain a good result. An undisplaced fracture can be managed nonoperatively by treating the underlying medical cause, but fractures at the risk of displacement or a displaced fracture may need operative treatment.

PMID- 29181363 TI - PREVALENCE OF BENIGN PROSTATIC HYPERPLASIA AND PROSTATE CANCER IN AFRICANS AND AFRICANS IN THE DIASPORA. AB - Background: There have been several publications on population or community prevalence of benign prostatic hyperplasia and prostate cancer from various countries and races but few reports are from Africa on Africans. Aim: A review on the prevalence of benign prostatic hyperplasia and prostate cancer in Africans and other races. Methodology: The current literature on prevalence of benign prostatic hyperplasia (BPH), prostate cancer (PC), and benign prostatic hyperplasia co-existing with prostate cancer in Africans and other races is reviewed. Results: Benign prostatic hyperplasia (BPH) prevalence in Ghana is responsible for 60% acute retention of urine and 28.6% of haematuria. Worldwide prevalence of BPH varies from 20 - 62% in men over 50 years and this includes USA, UK, Japan and Ghana. Reports from South Africa indicate prevalence of over 50% in adult males of 60 years. BPH co-existing with PC - Reports from USA, UK and Japan and Ghana reveal moderate association of BPH and PC. The co-existence of PC in patients being treated for BPH is 3 - 20% Prostate Cancer prevalence - There is high prevalence in USA, Scandinavian Countries, African Americans (AA) and Caribbean blacks. Ghana, Trinidad & Tobago have reported high prevalence of 6 -10% in men aged 50 years and above but others reported low prevalence in Africans from Africa. The low reporting from Africa of 10 - 40:100,000 is attributable to under reporting, absence of PSA screening/testing, lack of reliable cancer registries and poor medical facilities. Economic Costs of BPH and PC: BPH in the USA national direct costs are estimated at U$4Billion and individual costs of US$1536 annually. In Ghana, individual costs for BPH medications range from US$300 - 550 per year and cost for simple prostatectomy/TURP is estimated at US$1100. For prostate cancer, individual direct costs from Europe range from 6,575 - 12,000 euros, L2818.00 UK and over U$12,000 - 20,000 in USA per annum. In Ghana, individual direct costs ranges, for radical prostatectomy and external beam radiotherapy US$1250 - 1500, for brachytherapy 9,000 Euros, for hormonal therapy US$1600 - 3200) per year and US$510 for orchidectomy. Conclusion: Recent evidence although sparse indicate there is high prevalence of BPH and PC in Africans and men of African descent in diaspora, the low prevalence of BPH and PC reported from some African countries is likely to under reporting and future prevalence studies both in the living and deceased are recommended to reveal the true prevalence of BPH and PC in Africans though screening for PC in the living remains controversial. PMID- 29181365 TI - A COMMUNITY-BASED PREVALENCE OF PRESBYOPIA AND SPECTACLE COVERAGE IN SOUTHWEST NIGERIA. AB - Background: The use of population-based method to assess the prevalence of presbyopia and spectacle use is few even though it is more reliable compared to the commoner hospital based studies. This study was carried out to determine the need for spectacle services in our coverage area. Aim: To determine the prevalence of presbyopia among adults of 30 years old and above in Sagamu local government area of Ogun state, South-West, Nigeria. Design: The study was a population based descriptive and cross-sectional design. Setting: The study was carried out using a multistage cluster random sampling with probability proportional to size of regular adult residents of Sagamu Local Government area, Sagamu, Ogun state, Nigeria. Materials and Methods: Examination of respondents included administration of semi-structured interviewer assisted questionnaire and distance visual acuity measurement with or without pinhole at 6 meters using the Snellen's charts. Automated refraction with subjective refraction was carried out in all participants with presenting visual acuity (PVA) worse than 6/9 but with an improvement with pinhole. Near assessment was done at 40cm with the distance correction in place if required. Ocular examination was also carried out in all participants that had refraction including pupillary dilatation when indicated. Results: The prevalence of presbyopia was 80.9%. There was an increasing prevalence with age (p<0.001) with a 100% prevalence in the >=80 years age group. The mean add requirement was +2.24DS. The met presbyopic need was 22.9% and the unmet need 58%. The presbyopic spectacle coverage was 28.4% which was positively associated with younger age (p=0.034), attaining at least secondary school education (p<0.001), and living in an urban area (p<0.001). Conclusion: The prevalence of presbyopia is high in this community and found in persons younger than 40 years and the spectacle coverage for the population is low with a high unmet spectacle need. There is a need to provide near vision spectacles to a large proportion of residents in the community. PMID- 29181364 TI - MANAGEMENT OF PROSTATE CANCER IN ACCRA, GHANA. AB - Introduction: Africans living with prostate cancer in Africa face problems of early diagnosis and appropriate treatment. Aim: To study the clinical incidence of prostate cancer, risk factors, TNM stage, their management and outcomes. Methods: A prospective study of Prostate Cancer cases managed at Korle Bu Teaching Hospital and hospitals in Accra, diagnosed by history, abnormal PSA/DRE, physical examination and histologically confirmed by biopsy from 2004 to 2013 was carried out. The cases were TNM staged and managed by approved protocol. Results: There were 669 cases with a mean age 70+/-0.045SE years, median Gleason Score of 7, organ confined Prostate Cancer(PC) in 415(62%), locally advanced in 167(25%) and metastatic Prostate Cancer in 87(13%) cases. The cases were followed for median of 10 months to >= 84 months. Organ confined cases were managed by: Radical Prostatectomy (RP) 92 (13.8%) with a mortality of 0.3%; brachytherapy 70 (10.5%) with a mortality of 0.1% and External Beam Radiotherapy (EBRT) 155 (23%) with a mortality 0.7%. In all, 98 men constituting (14.1%) cases with a mean age of 75+0.25SE years, life expectancy <10 years were treated by hormonal therapy with a mortality of 1.7%. Twenty cases who were for active surveillance (GS6), PSA <10ng/ml, life expectancy <10 years later all opted for EBRT. Locally advanced cases 25% all had neoadjuvant hormonal therapy then Brachytherapy in 3 (0.4%) mortality 0.15% and EBRT in 64 (9.5%), mortality 0.59%. Hormonal therapy was given in 100 (15%) locally advanced cases, mortality 5%. Metastatic prostate cancer cases (13%) were managed by hormonal therapy, mortality 6%. Conclusion: Improved facilities and dedicated skilled teams led to a significant rise in proportion of organ confined Prostate Cancer from 15.3% to 62% curable by Radical Prostatectomy, brachytherapy or EBRT with longer disease free survival. PMID- 29181366 TI - ANAESTHETISTS' ATTITUDES AND PRACTICE OF INFORMED CONSENT IN NIGERIA. AB - Background: Informed consent is an integral part of a surgical and anaesthetic procedure, failure to obtain it may result in grave medico-legal implications. Aim: To determine the attitudes of Nigerian anaesthetists to informed consent. Methodology: The study population included physician anaesthetists who attended a continuous medical education programme in November 2015. The target was to cover over 50% of anaesthetists by convenience sampling. The responses to the questions were recorded and descriptive statistics were employed to calculate the various qualitative variables under study. Results: Fifty-six respondents were analysed, the majority were in the age group 31-40 years (37.5%), consultants were 51.79%, and males constituted 75%. The respondents agreed that the main purposes of informed consent included a need to improve the doctor/patient relationship in 36(64.29%), inform the patient about the desired benefits of the procedure in 32(57.14%), provide the doctor with greater protection against medical litigation in 32(57.14%), and to respect the patient's right of autonomy in 30(53.57%). The general consensus among the respondents was that the anaesthetist should explain to the patient what the procedure entails 40(71.43%), what the procedure aims to achieve and additional procedures that are likely to be necessary to the patient 41(73.21%). It was also agreed that there should be disclosure of all major risks/complications with incidence >1/20 in 29(51.79%) respondents, incidence >1/100 in 20(35.71%), incidence >1/1000, and incidence >1/10000 were 17(30.36%). The respondents who agreed that it is necessary to take consent before performing surgery or anaesthesia on patients and explained the procedure to patients were 48(85.71%). Conclusion: We determined that informed consent was an integral part of a surgical procedure. which helped to improve doctor/patient relationship, respected the patient's right of autonomy and provided the surgeon and anaesthetists with greater protection against medical litigation. It is paramount to disclose all major risk and complications. However, few anaesthetists 19(33.93%) obtain informed consent from their patients before epidural labour analgesia. PMID- 29181367 TI - RADIOTHERAPY TREATMENT OF KELOIDS IN IBADAN. AB - Background: The management of keloids has posed a difficult challenge to the patient, surgeon and radiation oncologist due to its high recurrence rate following treatment. Post-operative radiotherapy has been used to improve outcome of treatment by reducing recurrence. However, this is difficult in Africa where there are few Radiotherapy machines and some of those available are not the standard for the treatment for superficial tumours and lesions like keloids. Aim: To assess the pattern of presentation, treatment and outcomes in patients with keloids. Study design: A retrospective cross-sectional study. Setting: University College Hospital, Ibadan, Nigeria. Methodology: Records of all patients treated for keloids over a 25-year period were retrieved and their demographics, site and number of keloids, radiation treatment and outcome. The data obtained were analysed using the SPSS version 22. Results: In all, 172 cases were seen within the period with a male preponderance (57%), i.e. male: female ratio of 1.3:1. The age range was 12 - 73 years with a mean of 28.7 +/-14.53 years with 42.4% of the patients in the 20- 29 years bracket. Also, 69% of patients had a single keloid and the ears (35%) were the commonest sites in 35% of cases, the face (28.6%), the trunk (18.6%) and the neck (8.7%).All the patients had surgical excision followed by radiation therapy within 72 hours of surgery. They all received 12Gy in 2 fractions over 2 weeks except one that had 25Gy in 10 alternate daily fractions due to the large size of the tumour. There was no documented complication during and following treatment. The recurrence rate was 14.53%. Conclusion: Immediate postoperative radiotherapy of keloids is safe with good outcome and a low recurrence rate. PMID- 29181368 TI - CEPHALOMETRIC ASSESSMENT OF HYOID BONE POSITION IN NIGERIAN PATIENTS WITH BIMAXILLARY INCISOR PROCLINATION. AB - Background: Hyoid bone though constitute a small proportion of the human skeleton, its importance in relation to other facial structures cannot be overemphasized. Several studies have reported on hyoid bone position in relation to various types of malocclusion, however, to our knowledge, there has been no study on the relationship between the hyoid bone and bimaxillary incisor proclination. Aim: The aim of this study was to assess the relative position of hyoid bone in individuals with and without bimaxillary incisor proclination as well as other related demographic factors. Methodology: This was a comparative retrospective study of lateral cephalometric radiographs of orthodontic patients aged 12 to 40 years from two study locations (Ile-Ife and Lagos, Nigeria). Thirty randomly selected radiographs of patients with bimaxillary incisor proclination were compared with 30 radiographs of related cases with normal incisor relationship. These radiographs were manually traced using established cephalometric landmarks and analysed using SPSS 16. Independent t-test was used to compare mean values and statistical significant level was set as p<0.05. Results: Most of the linear and angular dental/skeletal measurements in relation to hyoid bone position showed no significant differences within the compared groups. Hyoid bone position (H-TV) was found to be more anteriorly located in male (p=0.02) and in bimaxillary incisor proclination (p=0.004) patients than their female and normal incisor relationship groups respectively. Similarly, there was a highly statistically significant difference in linear measurement of the lower incisor tip to hyoid bone position (H-LIT) between the adolescent and young adult groups (p=0.01). Conclusion: The hyoid bone position in male and bimaxillary incisor proclination subjects were more anteriorly located when compared with female and normal incisor relationship groups respectively. Similarly, the distance between the hyoid bone position and the lower incisor tip was longer in young adults than the adolescent group.

To our knowledge there are no reports in the literature about the clinical presentation of lymphomas in Ghana. Aim: To explored orbital and adnexal disorders among adult patients attending the Korle-Bu Teaching hospital, Accra. Methodology: Histological case notes of patients reporting to the orbital clinic of Korle-Bu Teaching Hospital, Eye Department from November 2004 to October 2016 with orbital and adnexial lympho-proliferative tumors were retrieved. Histopathology was performed at Sheffield Teaching hospital. Data collected included age, sex, symptoms at presentation and anatomic site of involvement. Histology and immune histochemistry data were generated. Results: A total of 18 patients were examined and entered into the study. The male to female ratio was 1.25:1. Twelve patients (70.6) presented with proptosis and 14 (77.8%) had orbital involvement. Two patients had isolated eyelid disease. Of those with orbital disease, three had simultaneously upper eyelid involvement. Out of the 18 cases, 11 (61.1%) were mucosa-associated lymphoid tissue (MALT) lymphomas. Only males 40 years and above were affected, compared with females who presented at any age. Patients above 60 years reported early (i.e. <3 months) compared with patients below 40 years who mostly reported after 1 year. Conclusion: This study reports pattern of epidemiological and clinical presentation of orbital and adnexal lymphomas as seen in Ghana, West Africa. Though there were some variations in the clinical presentation the histological subtypes represented seem to be similar to those reported in other parts of the world.

AB - Background: Inflammatory bowel disease (IBD) patients are not routinely screened for depression and anxiety despite knowledge of an increased prevalence in people with chronic disease and negative effects on quality of life. Methods: Prevalence of anxiety and depression was assessed in IBD outpatients through retrospective chart review. The presence of anxiety and/or depression was determined using the Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 self-report questionnaires or by diagnosis through psychiatric interview. Patient demographics, disease characteristics, and medication information were also collected. Multivariable analysis was used to determine associations between patient factors and depression and anxiety. Results: 327 patient charts were reviewed. Rates of depression and anxiety were found to be 25.8% and 21.2%, with 30.3% of patients suffering from depression and/or anxiety. Disease activity was found to be significantly associated with depression and/or anxiety (p = 0.01). Females were more likely to have anxiety (p = 0.01). Conclusion: A significant proportion of IBD patients suffer from depression and/or anxiety. The rates of these mental illnesses would justify screening and referral for psychiatric treatment in clinics treating this population. Patients with active disease are particularly at risk for anxiety and depression. PMID- 29181374 TI - Malignancy-Induced Hypercalcemia-Diagnostic Challenges. AB - Hypercalcemia in children is a rare metabolic finding. The clinical picture is usually non-specific, and the etiology includes several entities (metabolic, nutritional, drug-induced, inflammatory, cancer-associated, or genetic) depending on the age at presentation, but severe hypercalcemia is associated mainly with malignancy in childhood and sepsis in neonates. Severe parathyroid hormone (PTH) suppressed hypercalcemia is challenging and requires multidisciplinary diagnostic and therapeutic approaches to (i) confirm or rule out a malignant cause, (ii) treat it and its potentially dangerous complications. We report a case of severe and complicated PTH-independent hypercalcemia in a symptomatic 3-year-old boy. His age, severity of hypercalcemia and its complicated course, and the first imaging reports were suggestive of malignancy. The first bone and kidney biopsies and bone marrow aspiration were normal. The definitive diagnosis was a malignant induced hypercalcemia, and we needed 4 weeks to assess other differential diagnoses and to confirm, on histopathological and immunochemical base, the malignant origin of hypercalcemia. Using this case as an illustrative example, we suggest a diagnostic approach that underlines the importance of repeated histology if the clinical suspicion is malignancy-induced hypercalcemia. Effective treatment is required acutely to restore calcium levels and to avoid complications.

PMID- 29181376 TI - Automated Solid-Phase Protein Modification with Integrated Enzymatic Digest for Reaction Validation: Application of a Compartmented Microfluidic Reactor for Rapid Optimization and Analysis of Protein Biotinylation. AB - Protein modification by covalent coupling of small ligands or markers is an important prerequisite for the use of proteins in many applications. Well-known examples are the use of proteins with fluorescent markers in many in vivo experiments or the binding of biotinylated antibodies via biotin-streptavidin coupling in the frame of numerous bioassays. Multiple protocols were established for the coupling of the respective molecules, e.g., via the C and N-terminus, or via cysteines and lysines exposed at the protein surface. Still, in most cases the conditions of these standard protocols are only an initial guess. Optimization of the coupling parameters like reagent concentrations, pH, or temperature may strongly increase coupling yield and the biological activity of the modified protein. In order to facilitate the process of optimizing coupling conditions, a method was developed which uses a compartmented microfluidic reactor for the rapid screening of different coupling conditions. In addition, the system allows for the integration of an enzymatic digest of the modified protein directly after modification. In combination with a subsequent MALDI-TOF analysis of the resulting fragments, this gives a fast and detailed picture not only of the number and extent of the generated modifications but also of their position within the protein sequence. The described process was demonstrated for biotinylation of green fluorescent protein. Different biotin-excesses and different pH-values were tested in order to elucidate the influence on the modification extent and pattern. In addition, the results of solid-phase based modifications within the microfluidic reactor were compared to modification patterns resulting from coupling trials with unbound protein. As expected, modification patterns of immobilized proteins showed clear differences to the ones of dissolved proteins. PMID- 29181377 TI - Mitochondria As Sources and Targets of Methane. AB - This review summarizes the current knowledge on the role of mitochondria in the context of hypoxic cell biology, while providing evidence of how these mechanisms are modulated by methane (CH4). Recent studies have unambiguously confirmed CH4 bioactivity in various in vitro and in vivo experimental models and established the possibility that CH4 can affect many aspects of mitochondrial physiology. To date, no specific binding of CH4 to any enzymes or receptors have been reported, and it is probable that many of its effects are related to physico-chemical properties of the non-polar molecule. (i) Mitochondria themselves can be sources of endogenous CH4 generation under oxido-reductive stress conditions; chemical inhibition of the mitochondrial electron transport chain with site-specific inhibitors leads to increased formation of CH4 in eukaryote cells, in plants, and in animals. (ii) Conventionally believed as physiologically inert, studies cited in this review demonstrate that exogenous CH4 modulates key events of inflammation. The anti-apoptotic effects of exogenously administered CH4 are also recognized, and these properties also suggest that CH4-mediated intracellular signaling is closely associated with mitochondria. (iii) Mitochondrial substrate oxidation is coupled with the reduction of molecular oxygen, thus providing energy for cellular metabolism. Interestingly, recent in vivo studies have shown improved basal respiration and modulated mitochondrial oxidative phosphorylation by exogenous CH4. Overall, these data suggest that CH4 liberation and effectiveness in eukaryotes are both linked to hypoxic events and redox regulation and support the notion that CH4 has therapeutic roles in mammalian pathophysiologies.

AB - The objectives of this article are as follows: (1) to describe the assessment protocol used to outline people with probable dementia in Primary Health Care; (2) to show the methodological design and procedure to obtain a representative sample of patients with probable dementia; and (3) to report the main characteristics of the sample collected in the context of the study "Characteristics and needs of people with probable dementia." The study protocol was based on the "Community Assessment of Risk and Treatment Strategies (CARTS) Program" and is composed by a set of instruments that allow the assessment of older adults with probable dementia in several areas (health, psychological, functionality, and other). Descriptive analysis was used to characterize the final sample (n = 436). The study protocol as well as the methodological procedure to obtain the referral of research participants and data collection on the condition of people with probable dementia in Primary Health Care proved to be a valuable tool to obtain a sample of patients distributed by the full range of probable dementia in a large geographical area. Results may allocate the design of care pathways for old people with cognitive disorders to prevent, delay impairment, and/or optimize quality of life of patients. PMID- 29181380 TI - Production, Preservation, and Transfer of South American Camelid Embryos. AB - The current review summarizes progress in the field of in vitro and in vivo production of South American Camelid embryos. Both methods require ovarian superstimulation (with FSH and eCG) to obtain multiple ovulations (in vivo embryo production) or to induce follicle growth for oocyte collection (in vitro embryo production). Moreover, superstimulation entails prior administration of hormones that inhibit follicular growth (progesterone, progestagens, and estrogens). Cumulus-oocyte complexes obtained must mature in vivo (buserelin administration) or in vitro to then be subjected to in vitro fertilization or intracytoplasmic sperm injection. All these techniques also require morphologically normal, motile spermatozoa to achieve fertilization. Methods used to decrease semen viscosity and to select the best spermatozoa (Percoll(r); Androcoll-ETM) are described. Additionally, nuclear transfer or cloning has been applied in llamas. Up to now, embryo deep-freezing and vitrification have progressed slowly but are at the height of development. Embryos that are obtained by any of these techniques, either in vivo or in vitro, need to be transferred to synchronized recipient females. The best results are achieved after transfer to the left uterine horn with an ipsilateral ovulation. No live offspring have been obtained after the transfer of cryopreserved embryos. Applying reproductive biotechnologies, such as those described, will permit the expansion of genetically selected animals in the population and also that of wild camelid species, vicunas, and guanacos, whose embryos could then be transferred to the uterus of domestic species. PMID- 29181379 TI - Molecular Autopsy for Sudden Death in the Young: Is Data Aggregation the Key? AB - The Scripps molecular autopsy study seeks to incorporate genetic testing into the postmortem examination of cases of sudden death in the young (<45 years old). Here, we describe the results from the first 2 years of the study, which consisted of whole exome sequencing (WES) of a cohort of 50 cases predominantly from San Diego County. Apart from the individual description of cases, we analyzed the data at the cohort-level, which brought new perspectives on the genetic causes of sudden death. We investigated the advantages and disadvantages of using WES compared to a gene panel for cardiac disease (usually the first genetic test used by medical examiners). In an attempt to connect complex clinical phenotypes with genotypes, we classified samples by their genetic fingerprint. Finally, we studied the benefits of analyzing the mitochondrial DNA genome. In this regard, we found that half of the cases clinically diagnosed as sudden infant death syndrome had an increased ratio of heteroplasmic variants, and that the variants were also present in the mothers. We believe that community based data aggregation and sharing will eventually lead to an improved classification of variants. Allele frequencies for the all cases can be accessed via our genomics browser at https://genomics.scripps.edu/browser. PMID- 29181381 TI - Impact of Dietary Galacto-Oligosaccharide (GOS) on Chicken's Gut Microbiota, Mucosal Gene Expression, and Salmonella Colonization. AB - Preventing Salmonella colonization in young birds is key to reducing contamination of poultry products for human consumption (eggs and meat). While several Salmonella vaccines have been developed that are capable of yielding high systemic antibodies, it is not clear how effective these approaches are at controlling or preventing Salmonella colonization of the intestinal tract. Effective alternative control strategies are needed to help supplement the bird's ability to prevent Salmonella colonization, specifically by making the cecum less hospitable to Salmonella. In this study, we investigated the effect of the prebiotic galacto-oligosaccharide (GOS) on the cecal microbiome and ultimately the carriage of Salmonella. Day-old pullet chicks were fed control diets or diets supplemented with GOS (1% w/w) and then challenged with a cocktail of Salmonella Typhimurium and Salmonella Enteritidis. Changes in cecal tonsil gene expression, cecal microbiome, and levels of cecal and extraintestinal Salmonella were assessed at 1, 4, 7, 12, and 27 days post infection. While the Salmonella counts were generally lower in the GOS-treated birds, the differences were not significantly different at the end of the experiment. However, these data demonstrated that treatment with the prebiotic GOS can modify both cecal tonsil gene expression and the cecal microbiome, suggesting that this type of treatment may be useful as a tool for altering the carriage of Salmonella in poultry. PMID- 29181382 TI - Reinnervation of the diaphragm by the inferior laryngeal nerve to the phrenic nerve in ventilator-dependent tetraplegic patients with C3-5 damage. AB - The aim of this study was to evaluate the feasibility of unilateral diaphragmatic reinnervation in humans by the inferior laryngeal nerve. This pilot study included chronically ventilated tetraplegic patients with destruction of phrenic nerve motoneurons. Five patients were included. They all had a high level of tetraplegia, with phrenic nerve motor neuron destruction. They were highly dependent on ventilation, without any possibility of weaning. They did not have other chronic pathologies, especially laryngeal disease. They all had diaphragmatic explorations to diagnose the destruction of the motoneurons of the phrenic nerves and nasoendoscopy to be sure that they did not have laryngeal or pharyngeal disease. Then, surgical anastomosis of the right phrenic nerve was performed with the inferior laryngeal nerve, by a cervical approach. A laryngeal reinnervation was performed at the same time, using the ansa hypoglossi. One patient was excluded because of a functional phrenic nerve and one patient died 6 months after the surgery of a cardiac arrest. The remaining three patients were evaluated after the anastomosis every 6 months. They did not present any swallowing or vocal alterations. In these three patients, the diaphragmatic explorations showed that there was a recovery of the diaphragmatic electromyogram of the right and left hemidiaphragms after 1 year. Two patients had surgical diaphragmatic explorations for diaphragmatic pacing 18-24 months after the reinnervation with excellent results. At 36 months, none of the patients could restore their automatic ventilation. In conclusion, this study demonstrated that diaphragmatic reinnervation by the inferior laryngeal nerve is effective, without any vocal or swallowing complications. PMID- 29181383 TI - High emergency organ allocation rule in lung transplantation: a simulation study. AB - The scarcity of suitable organ donors leads to protracted waiting times and mortality in patients awaiting lung transplantation. This study aims to assess the short- and long-term effects of a high emergency organ allocation policy on the outcome of lung transplantation. We developed a simulation model of lung transplantation waiting queues under two allocation strategies, based either on waiting time only or on additional criteria to prioritise the sickest patients. The model was informed by data from the United Network for Organ Sharing. We compared the impact of these strategies on waiting time, waiting list mortality and overall survival in various situations of organ scarcity. The impact of a high emergency allocation strategy depends largely on the organ supply. When organ supply is sufficient (>95 organs per 100 patients), it may prevent a small number of early deaths (1 year survival: 93.7% against 92.4% for waiting time only) without significant impact on waiting times or long-term survival. When the organ/recipient ratio is lower, the benefits in early mortality are larger but are counterbalanced by a dramatic increase of the size of the waiting list. Consequently, we observed a progressive increase of mortality on the waiting list (although still lower than with waiting time only), a deterioration of patients' condition at transplant and a decrease of post-transplant survival times. High emergency organ allocation is an effective strategy to reduce mortality on the waiting list, but causes a disruption of the list equilibrium that may have detrimental long-term effects in situations of significant organ scarcity. PMID- 29181384 TI - Identification and Characterization of the Diverse Stress-Responsive R2R3-RMYB Transcription Factor from Hibiscus sabdariffa L. AB - Various regulatory proteins play a fundamental role to manage the healthy plant growth under stress conditions. Differential display reverse transcriptase PCR and random amplification of cDNA ends (RACE) was used to explore the osmotic stress-responsive transcripts. We identified and characterized the salt stress responsive R2R3 type RMYB transcription factor from Hibiscus sabdariffa which has an open reading frame of 690 bp, encoding 229 long chain amino acids. In silico analysis confirmed the conserved R2 and R3 domain as well as an NLS-1 localization site. The deduced amino acids of RMYB shared 83, 81, 80, 79, 72, 71, and 66% homology with Arabidopsis thaliana, Glycine max, Oryza sativa, Zea maize, Malus domestica, Populus tremula * Populus alba, and Medicago sativa specific MYB family, respectively. We observed the gene upregulation in stem, leaf, and root tissue in response to abiotic stress. Furthermore, RMYB gene was cloned into plant expression vector under CaMV35S promoter and transformed to Gossypium hirsutum: a local cotton cultivar. Overexpression of RMYB was observed in transgenic plants under abiotic stresses which further suggests its regulatory role in response to stressful conditions. The RMYB transcription factor overexpressing in transgenic cotton plants may be used as potential agent for the development of stress tolerant crop cultivars. PMID- 29181385 TI - Calcium Ionophore, Calcimycin, Kills Leishmania Promastigotes by Activating Parasite Nitric Oxide Synthase. AB - Leishmaniasis is an infectious disease caused by protozoan parasites of the genus Leishmania. There is no vaccine against human leishmaniasis and the treatment of the disease would benefit from a broader spectrum and a higher efficacy of leishmanicidal compounds. We analyzed the leishmanicidal activity and the mechanism of action of the calcium ionophore, calcimycin. L. major promastigotes were coincubated with calcimycin and the viability of the cells was assessed using resazurin assay. Calcimycin displayed dose-dependent effect with IC50 = 0.16 MUM. Analysis of propidium iodide/LDS-751 stained promastigotes revealed that lower concentrations of calcimycin had cytostatic effect and higher concentrations had cytotoxic effect. To establish the mechanism of action of calcimycin, which is known to stimulate activity of mammalian constitutive nitric oxide synthase (NOS), we coincubated L. major promastigotes with calcimycin and selective NOS inhibitors ARL-17477 or L-NNA. Addition of these inhibitors substantially decreased the toxicity of calcimycin to Leishmania promastigotes. In doing so, we demonstrated for the first time that calcimycin has a direct leishmanicidal effect on L. major promastigotes. Also, we showed that Leishmania constitutive Ca2+/calmodulin-dependent nitric oxide synthase is involved in the parasite cell death. These data suggest activation of Leishmania nitric oxide synthase as a new therapeutic approach. PMID- 29181386 TI - The Influence of Different Oregano Species on the Antioxidant Activity Determined Using HPLC Postcolumn DPPH Method and Anticancer Activity of Carvacrol and Rosmarinic Acid. AB - The aim of this study was to evaluate concentration-dependent antioxidant and anticancer activities of CA and RA in ethanol extracts of three different Oregano species (Origanum onites L., Origanum vulgare L., and Origanum vulgare ssp. hirtum). The study revealed the highest RA antioxidant activity in O. vulgare ssp. hirtum (9550 +/- 95 mmol/g) and the lowest in O. vulgare L. (2605 +/- 52 mmol/g) (p < 0.05). The highest CA amount was present in O. onites L., which was 1.8 and 4.7 times higher (p < 0.05) than in O. vulgare ssp. hirtum and O. vulgare L., respectively. The anticancer activity was evaluated on human glioblastoma (U87) and triple-negative breast cancer (MDA-MB231) cell lines in vitro. RA anticancer activity was negligible. CA and the extracts were about 1.5-2 times more active against MDA-MB231 cell line (p < 0.05) compared to U87 cell line. The anticancer activities of three tested extracts were similar against U87 cell line (p > 0.05) but they had different activities against MDA-MB231 cell line. PMID- 29181387 TI - cAMP Response Element Binding Protein Expression in the Hippocampus of Rhesus Macaques with Chronic Ephedrine Addiction. AB - Background: Drug addiction is classified as a chronic relapse nature brain disease with complicated neurobiology mechanisms. There are an increasing number of researchers that are investigating the possible mechanisms for solving the thorny problem. Methods: The model of chronic addiction of rhesus monkey ephedrine was established, where changes in body weight and behavior were monitored. The expression of cAMP response element binding protein (CREB) in the hippocampus of rhesus monkeys was identified by real-time PCR and Western blot. Results: We were successful in establishing the chronic ephedrine addiction model in the rhesus macaques. They exhibited changes in body weight and behavior. Immunofluorescence showed that CREB was expressed in the nucleus of the hippocampus, and the expression of CREB mRNA and protein in the hippocampus were increased by real-time PCR and Western blot. The CREB positive expression in the hippocampus of the modeling group was significantly higher than in the control group. Conclusions: The changes of body weight and behavior of the rhesus monkeys after ephedrine chronic addiction were significant. The changes of CREB in the hippocampus of rhesus macaques with ephedrine chronic addiction are important molecular mechanisms, and the upregulation of CREB may be involved in the physiological pathology and behavior process in individuals with chronic ephedrine addiction. PMID- 29181388 TI - Early Production of the Neutrophil-Derived Lipid Mediators LTB4 and LXA4 Is Modulated by Intracellular Infection with Leishmania major. AB - Recruitment of neutrophil granulocytes to sites of infectious tissue damage is an early event in innate immune responses. Following chemotactic signals neutrophils establish a first line of defense in a swarm-like manner. Intracellular pathogens such as Leishmania major can, however, evade neutrophil-mediated killing and survive inside neutrophils. To achieve this the parasites evolved potent evasion mechanisms. Since neutrophils are a major source of inflammation regulating lipid mediators, we hypothesized that intracellular infection modifies the release of pro- and anti-inflammatory lipid mediators like leukotriene B4 (LTB4) and lipoxin A4 (LXA4), respectively. In the present study, we demonstrated in vitro that L. major-infected primary human neutrophils release an increased amount of LTB4, whereas LXA4 liberation is reduced during the first hours of infection. To investigate whether lipid mediator modulation is a common feature in intracellular infections, we tested the impact of an infection with Anaplasma phagocytophilum. Similarly to L. major, neutrophil infection with A. phagocytophilum led to an enhanced release of LTB4 and decreased LXA4 production. Together, our findings indicate that intracellular infections modulate the lipid mediator profile of neutrophils. This effect is likely to contribute to the survival of the pathogens in neutrophils and to the outcome of the infections. PMID- 29181389 TI - Cucurbitaceae Seed Protein Hydrolysates as a Potential Source of Bioactive Peptides with Functional Properties. AB - Seeds from Cucurbitaceae plants (squashes, pumpkins, melons, etc.) have been used both as protein-rich food ingredients and nutraceutical agents by many indigenous cultures for millennia. However, relatively little is known about the bioactive components (e.g., peptides) of the Cucurbitaceae seed proteins (CSP) and their specific effects on human health. Therefore, this paper aims to provide a comprehensive review of latest research on bioactive and functional properties of CSP isolates and hydrolysates. Enzymatic hydrolysis can introduce a series of changes to the CSP structure and improve its bioactive and functional properties, including the enhanced protein solubility over a wide range of pH values. Small sized peptides in CSP hydrolysates seem to enhance their bioactive properties but adversely affect their functional properties. Therefore, medium degrees of hydrolysis seem to benefit the overall improvement of bioactive and functional properties of CSP hydrolysates. Among the reported bioactive properties of CSP isolates and hydrolysates, their antioxidant, antihypertensive, and antihyperglycaemic activities stand out. Therefore, they could potentially substitute synthetic antioxidants and drugs which might have adverse secondary effects on human health. CSP isolates and hydrolysates could also be implemented as functional food ingredients, thanks to their favorable amino acid composition and good emulsifying and foaming properties. PMID- 29181390 TI - Gender Differences in the Progression of Experimental Chronic Kidney Disease Induced by Chronic Nitric Oxide Inhibition. AB - Chronic kidney disease (CKD) is considered a public health problem, assuming epidemic proportions worldwide. In this context, the preponderance of CKD prevalence in male over age-matched female patients is of note. In the present study, we investigated the impact of the gender on the development of experimental CKD induced by chronic nitric oxide (NO) inhibition in Wistar male and female rats through the administration of L-NAME. CKD model induced by L-NAME is characterized by systemic vasoconstriction, resulting in severe hypertension, albuminuria, renal ischemia, glomerulosclerosis, interstitial expansion, and macrophage infiltration. After 30 days of CKD induction, male NAME rats exhibited remarkable albuminuria, augmented cortical histological damage, interstitial inflammation, and fibrosis. Age-matched female NAME rats showed significantly lower albuminuria, diminished glomerular ischemia, and glomerulosclerosis, as well as a significant reduction in the expression of alpha-smooth muscle actin renal interstitial Ang II+ cells. Thus, the present study demonstrated that female rats submitted to the NAME model developed less severe CKD than males. Female renoprotection could be promoted by both the estrogen anti-inflammatory activity and/or by the lack of testosterone, related to renin-angiotensin aldosterone system hyperactivation and fibrogenesis. However, the influence of sex hormones on the progression of CKD needs to be further investigated. PMID- 29181391 TI - Barcoding the Dendrobium (Orchidaceae) Species and Analysis of the Intragenomic Variation Based on the Internal Transcribed Spacer 2. AB - Many species belonging to the genus Dendrobium are of great commercial value. However, their difficult growth conditions and high demand have caused many of these species to become endangered. Indeed, counterfeit Dendrobium products are common, especially in medicinal markets. This study aims to assess the suitability of the internal transcribed spacer 2 (ITS2) region as a marker for identifying Dendrobium and to evaluate its intragenomic variation in Dendrobium species. In total, 29,624 ITS2 copies from 18 species were obtained using 454 pyrosequencing to evaluate intragenomic variation. In addition, 513 ITS2 sequences from 26 Dendrobium species were used to assess its identification suitability. The highest intragenomic genetic distance was observed in Dendrobium chrysotoxum (0.081). The average intraspecific genetic distances of each species ranged from 0 to 0.032. Phylogenetic trees based on ITS2 sequences showed that most Dendrobium species are monophyletic. The intragenomic and intraspecies divergence analysis showed that greater intragenomic divergence is mostly correlated with larger intraspecific variation. As a major ITS2 variant becomes more common in genome, there are fewer intraspecific variable sites in ITS2 sequences at the species level. The results demonstrated that the intragenomic multiple copies of ITS2 did not affect species identification. PMID- 29181392 TI - Long-Term Effectiveness of a Stress Management Intervention at Work: A 9-Year Follow-Up Study Based on a Randomized Wait-List Controlled Trial in Male Managers. AB - Objective: Short- and medium-term effectiveness (up to 3 years) of individual level stress management interventions (SMI) at work were demonstrated, yet long term effectiveness remains unexplored. We therefore aimed to address this research gap. Methods: 94 male middle managers participated in a randomized wait list controlled trial between 2006 and 2008 and in a post-trial-follow-up survey in 2015. During the first two years, all received an 18-hour psychotherapeutic SMI intervention which was based on the Effort-Reward Imbalance (ERI) model: tackling stressor on mismatch between effort and reward and promoting recovery on overcommitment. Work stress (i.e., ERI indicators) was the primary outcome, and the secondary outcome was depressive symptoms. The long-term effectiveness of the SMI was examined by mixed modeling, using an external control group (n = 94). Results: Effort and reward were substantially improved with significant intervention * time interaction effects (p < 0.001) compared to the external control group; effects on overcommitment and depressive symptoms were also significant (p < 0.05 and p < 0.01, resp.), though their trajectories in the intervention group were less sustainable. Conclusions: The effectiveness of this psychotherapeutic SMI at work based on the ERI model was observed over a 9-year period, particularly on the effort-reward ratio.

AB - Background: Isometric tunnel placement for anterior bundle of the medial collateral ligament (MCL) reconstruction is mandatory for successful surgery. Purpose: This study aimed to demonstrate a useful method for identifying isometric tunnel placement using a single computed tomography (CT) scan. Study Design: Descriptive Laboratory Study. Methods: Five normal elbows were scanned at 4 different flexion angles at 45 degrees increment. Three-dimensional models were analyzed using 2 different approaches: single and multiple CT scans methods. Ligament footprints in the humerus and the ulna were registered. Ligament length and isometric points were defined. The locations of the isometric points were imported into both methods to be compared. Results: There was no significant difference between 2 methods in calculating the length in every zone. There was also no significant difference in determining isometric ligament's origin point, which is located approximately 18.2 +/- 4.0 mm and 18.4 +/- 2.9 mm for single and multiple CT, respectively, measured inferolaterally from medial epicondyle. Conclusions: A solid preoperative plan is critical when predicting tunnel locations due to the difficulty in finding isometric points and the individuality of optimal bone tunnel locations. Using single CT scan, optimal locations can be predicted with the same accuracy as a multiple CT scans with less radiation exposure. PMID- 29181397 TI - Preoperative C-Reactive Protein as a Risk Factor for Postoperative Delirium in Elderly Patients Undergoing Laparoscopic Surgery for Colon Carcinoma. AB - Background: Postoperative delirium (POD) is a very common complication in operative disciplines, especially in those elderly patients after cardiac surgery. This study aimed to investigate the relationship between C-reactive protein (CRP) and POD in elderly patients undergoing laparoscopic surgery for colon carcinoma. Methods: 160 elderly patients scheduled to undergo selective laparoscopic surgery for colon carcinoma were prospectively recruited in this present study. The preoperative demographic and medical characteristics, intraoperative variables, and postoperative complications were all recorded in detail. POD assessment was performed once a day for the first 3 days and at 7th day after surgery, respectively. CRP concentrations preoperatively and on postoperative days 1, 2, and 3 were measured by using human enzyme linked immunosorbent assay (ELISA). Results: Of all the 160 enrolled patients, 39 had suffered POD with a POD incidence of 24.4% within the first week after the operation. The univariate analysis and multiple logistic regression analysis suggested preoperative CRP concentrations as the only independent predicator for POD in patients undergoing laparoscopic surgery for colon carcinoma (OR: 5.87; 95% CI: 2.22-11.4; P = 0.018). Conclusions: This present study highlighted the predictive role of preoperative CRP concentrations for POD in elderly patients undergoing laparoscopic surgery for colon carcinoma. PMID- 29181398 TI - Rheumatoid Arthritis Affecting the Upper Cervical Spine: Biomechanical Assessment of the Stabilizing Ligaments. AB - Diameters of anterior and posterior atlantodental intervals (AADI and PADI) are diagnostically conclusive regarding ongoing neurological disorders in rheumatoid arthritis. MRI and X-ray are mostly used for patients' follow-up. This investigation aimed at analyzing these intervals during motion of cervical spine, when transverse and alar ligaments are damaged. AADI and PADI of 10 native, human cervical spines were measured using lateral fluoroscopy, while the spines were assessed in neutral position first, in maximal inclination second, and in maximal extension at last. First, specimens were evaluated under intact conditions, followed by analysis after transverse and alar ligaments were destroyed. Damage of the transverse ligament leads to an increase of the AADI's diameter about 0.65 mm in flexion and damage of alar ligaments results in significant enhancement of 3.59 mm at mean. In extension, the AADI rises 0.60 mm after the transverse ligament was cut and 0.90 mm when the alar ligaments are damaged. After all ligaments are destroyed, AADI assessed in extension closely resembles AADI at neutral position. Ligamentous damage showed an average significant decrease of the PADI of 1.37 mm in the first step and of 3.57 mm in the second step in flexion, while it is reduced about 1.61 mm and 0.41 mm in the extended and similarly in the neutrally positioned spine. Alar and transverse ligaments are both of obvious importance in order to prevent AAS and movement-related spinal cord compression. Functional imaging is necessary at follow-up in order to identify patients having an advanced risk of neurological disorders. PMID- 29181395 TI - Modulating Neuroinflammation to Treat Neuropsychiatric Disorders. AB - Neuroinflammation is recognised as one of the potential mechanisms mediating the onset of a broad range of psychiatric disorders and may contribute to nonresponsiveness to current therapies. Both preclinical and clinical studies have indicated that aberrant inflammatory responses can result in altered behavioral responses and cognitive deficits. In this review, we discuss the role of inflammation in the pathogenesis of neuropsychiatric disorders and ask the question if certain genetic copy-number variants (CNVs) associated with psychiatric disorders might play a role in modulating inflammation. Furthermore, we detail some of the potential treatment strategies for psychiatric disorders that may operate by altering inflammatory responses. PMID- 29181399 TI - MRI-Based Estimation of Scalar Cochlear-Implant Electrode Position. AB - The position of the cochlear-implant electrode is important to audiological outcomes after cochlear implantation. The common technique to evaluate the intracochlear electrode's position involves the use of ionized radiation in MSCT, DVT, or flat-panel tomography (FPT). Recent advances in knowledge regarding the handling of MRI artifacts in cochlear implantees indicate that estimating the intracochlear electrode's position with an MRI could be possible. This study's aim was to evaluate the ipsilaterally position of electrodes using MRI at 1.5 T. In a retrospective study of 10 implantees with postoperative need for MRI scanning, we evaluated the intrascalar electrode's position using a T2-weighted sequence at 1.5 T. We compared the resulting estimate of the intracochlear position with the estimates from the postoperative FPT scan and the intraoperative NRT ratio. For each ear, the MRI-estimated scalar position corresponded with the estimated positions from the FPT and NRT ratio. For eight ears, a scala tympani's position was observed in the MRI. In one case, an electrode scalar translocation was found. In one case, the scala vestibuli's position was observed. Thus, MRI-based estimation of the scalar position of a cochlear-implant electrode is possible. Limitations to this method include implant-specific magnet and fixation configurations, which can cause complications. PMID- 29181400 TI - Effects of Nitric Oxide on Renal Proximal Tubular Na+ Transport. AB - Nitric oxide (NO) has a wide variety of physiological functions in the kidney. Besides the regulatory effects in intrarenal haemodynamics and glomerular microcirculation, in vivo studies reported the diuretic and natriuretic effects of NO. However, opposite results showing the stimulatory effect of NO on Na+ reabsorption in the proximal tubule led to an intense debate on its physiological roles. Animal studies have showed the biphasic effect of angiotensin II (Ang II) and the overall inhibitory effect of NO on the activity of proximal tubular Na+ transporters, the apical Na+/H+ exchanger isoform 3, basolateral Na+/K+ ATPase, and the Na+/HCO3- cotransporter. However, whether these effects could be reproduced in humans remained unclear. Notably, our recent functional analysis of isolated proximal tubules demonstrated that Ang II dose-dependently stimulated human proximal tubular Na+ transport through the NO/guanosine 3',5'-cyclic monophosphate (cGMP) pathway, confirming the human-specific regulation of proximal tubular transport via NO and Ang II. Of particular importance for this newly identified pathway is its possibility of being a human-specific therapeutic target for hypertension. In this review, we focus on NO-mediated regulation of proximal tubular Na+ transport, with emphasis on the interaction with individual Na+ transporters and the crosstalk with Ang II signalling. PMID- 29181401 TI - Investigation into Hypoglycemic, Antihyperlipidemic, and Renoprotective Potentials of Dennettia tripetala (Pepper Fruit) Seed in a Rat Model of Diabetes. AB - This study investigated the hypoglycemic, antihyperlipidemic, and renoprotective potentials of Dennettia tripetala (DT) in a rat model of diabetes. The hypoglycemic activity in crude methanol seed extract of DT (CMEDT) and methanol seed fraction of DT (MFDT) measured by glucose oxidase method was increased by 47.37% and 28.72%, respectively, after 8 hours of administration. After 10 days of treatment, CMEDT and MFDT gave a good glycemic control with the highest percentage reduction of 75.82% and 71.34% in glucose level, respectively, which is closely compared with 79.91% in glibenclamide. Using the enzymatic assay and Friedewald's equation, there was a significant reduction in serum level of total cholesterol (TC), triglyceride (TG), very-low-density lipoprotein (VLDL), and low density lipoprotein (LDL) and a significant increase in high-density lipoprotein (HDL) (p < 0.05) following treatment with CMEDT and MFDT, when compared with the untreated group, although results varied in dosed groups, with high dose of MFDT showing a better lipid-lowering activity. High dose of MFDT improved lipid metabolism and increased percentage protection against atherogenesis by 44%. However, neither CMEDT nor MFDT ameliorated the renal biochemical alteration in urea and creatinine. Thus, the study demonstrates hypoglycemic and antihyperlipidemic potentials of DT seed in diabetes. PMID- 29181402 TI - Effects of rhBMP-2 Loaded Titanium Reinforced Collagen Membranes on Horizontal Bone Augmentation in Dogs. AB - The aim of this study was to evaluate the efficacy of growth factor loaded collagen membranes on new bone formation during horizontal bone augmentation. Mandibular defects (4 * 4 * 4 mm) were surgically prepared in six male beagle dogs, which were then protected with one of three types of membranes: (1) titanium mesh, (2) titanium reinforced collagen, or (3) rhBMP-2 loaded titanium reinforced collagen. Animals were euthanized 8 and 16 weeks after surgery, and nondecalcified specimens were prepared and histomorphologically investigated to determine the degree of osteogenesis. Data were analyzed with Friedman test. With respect to the degree of osteogenesis at earlier stage (8 weeks after surgery), there was significantly higher new bone ratio in rhBMP-2 loaded membrane group (p > 0.05). However, with respect to the long-term results (16 weeks after surgery), there were no significant differences among the three membranes (p > 0.05). Based on histomorphometric analysis, there were no significant differences in horizontal bone gaining ratio (p > 0.05). PMID- 29181403 TI - GosB Inhibits Triacylglycerol Synthesis and Promotes Cell Survival in Mouse Mammary Epithelial Cells. AB - It has been demonstrated that the activator protein related transcription factor Finkel-Biskis-Jinkins murine osteosarcoma B (GosB) is involved in preadipocyte differentiation and triacylglycerol synthesis. However, the role of GosB in regulating the synthesis of milk fatty acid in mouse mammary glands remains unclear. This research uncovered potentially new roles of GosB in suppressing milk fatty acid synthesis. Results revealed that GosB had the highest expression in lung tissue and showed a higher expression level during nonlactation than during lactation. GosB inhibited the expression of fatty acid synthase (FASN), stearoyl-CoA desaturase (SCD), fatty acid binding protein 4 (FABP4), diacylglycerol acyltransferase 1 (DGAT1), perilipin 2 (PLIN2), perilipin 3 (PLIN3), and C/EBPalpha in mouse mammary gland epithelial cells (MEC). In addition, GosB reduced cellular triglyceride content and the accumulation of lipid droplets; in particular, GosB enhanced saturated fatty acid concentration (C16:0 and C18:0). The PPARgamma agonist, rosiglitazone (ROSI), promoted apoptosis and inhibited cell proliferation. GosB increased the expression of Bcl 2 and protected MEC from ROSI-induced apoptosis. Furthermore, MECs were protected from apoptosis through the GosB regulation of intracellular calcium concentrations. These findings suggest that GosB may regulate mammary epithelial cells milk fat synthesis and apoptosis via PPARgamma in mouse mammary glands. PMID- 29181404 TI - Delta9-Tetrahydrocannabinol Prevents Cardiovascular Dysfunction in STZ-Diabetic Wistar-Kyoto Rats. AB - The aim of this study was to determine if chronic, low-dose administration of a nonspecific cannabinoid receptor agonist could provide cardioprotective effects in a model of type I diabetes mellitus. Diabetes was induced in eight-week-old male Wistar-Kyoto rats via a single intravenous dose of streptozotocin (65 mg kg 1). Following the induction of diabetes, Delta9-tetrahydrocannabinol was administered via intraperitoneal injection (0.15 mg kg-1 day-1) for an eight-week period until the animals reached sixteen weeks of age. Upon completion of the treatment regime, assessments of vascular reactivity and left ventricular function and electrophysiology were made, as were serum markers of oxidative stress and lipid peroxidation. Delta9-Tetrahydrocannabinol administration to diabetic animals significantly reduced blood glucose concentrations and attenuated pathological changes in serum markers of oxidative stress and lipid peroxidation. Positive changes to biochemical indices in diabetic animals conferred improvements in myocardial and vascular function. This study demonstrates that chronic, low-dose administration of Delta9-tetrahydrocannabinol can elicit antihyperglycaemic and antioxidant effects in diabetic animals, leading to improvements in end organ function of the cardiovascular system. Implications from this study suggest that cannabinoid receptors may be a potential new target for the treatment of diabetes-induced cardiovascular disease. PMID- 29181406 TI - Vertical-to-Horizontal Rotational Myocutaneous Flap for Repairing Cicatricial Lower Lid Ectropion: A Novel Surgical Technique. AB - Objective: To evaluate the efficacy and complications of a novel surgical technique for cicatricial lower lid ectropion that uses a vertical-to-horizontal (V-to-H) rotational myocutaneous flap procedure (Tsai procedure). Methods: We performed the V-to-H rotational myocutaneous flap procedure on 20 eyelids in 20 patients with mild to moderate cicatricial lower lid ectropion. A vertical myocutaneous flap was created from the anterior lamella of the vertical pedicle in the lateral third of the lower eyelid. Following a horizontal relaxing incision from the base of the flap, a vertical myocutaneous flap was created and rotated to horizontal. Two patients with combined cicatricial ectropion and paralytic lagophthalmos simultaneously underwent additional lateral tarsorrhaphy. Results: After a minimum follow-up period of 6 months, all patients showed good anatomical and functional improvement with decreased dependence on topical lubricants and a satisfactory cosmetic appearance. Two patients with combined cicatricial and paralytic ectropion had mild residual asymptomatic lagophthalmos. No patients required further revision surgery and there were no complications or recurrence. Conclusion: The V-to-H rotational myocutaneous flap technique was an effective and simple one-stage procedure for correcting cicatricial lower lid ectropion. It lengthened the anterior lamella and tightened horizontal eyelid laxity without the need for a free skin graft. PMID- 29181405 TI - Review of Natural Product-Derived Compounds as Potent Antiglioblastoma Drugs. AB - Common care for glioblastoma multiforme (GBM) is a surgical resection followed by radiotherapy and temozolomide- (TMZ-) based chemotherapy. Unfortunately, these therapies remain inadequate involving severe mortality and recurrence. Recently, new approaches discovering combinations of multiple inhibitors have been proposed along with the identification of key driver mutations that are specific to each patient. To date, this approach is still limited by the lack of effective therapy. Hopefully, novel compounds derived from natural products are suggested as potential solutions. Inhibitory effects of natural products on angiogenesis and metastasis and cancer suppressive effect of altering miRNA expression are provident discoveries. Angelica sinensis accelerates apoptosis by their key substances influencing factors of apoptosis pathways. Brazilin displays antitumor features by making influence on reactive oxygen species (ROS) intensity. Sargassum serratifolium, flavonoids, and so on have antimetastasis effect. Ficus carica controls miRNA that inhibits translation of certain secretory pathway proteins during the UPR. Serratia marcescens and patupilone (EPO 906) are physically assessed materials through clinical trials related to GBM progression. Consequently, our review puts emphasis on the potential of natural products in GBM treatment by regulating multiple malignant cancer-related pathway solving pending problem such as reducing toxicity and side effect. PMID- 29181407 TI - Tomographic Evaluation of the Lower Incisor's Bone Limits in Mandibular Symphysis of Orthodontically Untreated Adults. AB - The amount of available bone in the lower incisor region is critical for periodontal preservation when planning large anteroposterior dental movements. The aims of this study were to evaluate bone limits of the lower incisors in the mandibular symphysis and to verify whether they are influenced by facial growth patterns, lower incisor inclinations, skeletal anteroposterior relationships, or patient age. Tomographic images of 40 orthodontically untreated patients were evaluated and measurements of width and height of the mandibular symphysis, thickness on the lingual and labial sides of the alveolar bone, and thickness of the entire alveolar bone were performed in sagittal view. The following cephalometric measurements were also evaluated: growth pattern (FHI), lower incisor inclination (IMPA), and skeletal anteroposterior relationships (AO-BO). Pearson's correlation test was used to assess associations among bone measurements, cephalometric measurements, and patients' ages. Weak to moderate positive correlations between FHI and bone measurements on the labial side of the incisors and total alveolar width were found. The height of the symphysis had a moderate negative correlation with FHI. It was concluded that patient age, FHI, and IMPA influenced bone limits of the lower incisors in the mandibular symphysis, while AO-BO had no influence. PMID- 29181408 TI - Body Posture Asymmetry in Prematurely Born Children at Six Years of Age. AB - Aims: The purpose of the study was to assess body posture asymmetries in the standing and sitting position in prematurely born children at six years of age. Study Design and Subjects: We measured trunk symmetry in coronal plane. The study was carried out in a group of 101 children, aged 6-7 years, mean age of 6.63, including 50 preterm children born at gestational age <32 weeks (preterm group) and 51 full-term children (control group). Outcome Measures: Trunk symmetry in coronal plane was measured using photogrammetric technique with Mora 4G CQ Elektronik. The subjects were examined in standing and sitting position. Statistical analyses were carried out using Shapiro-Wilk W-test, Student's t test, Mann-Whitney U test, and Pearson's chi-squared test. Statistical significance was assumed at p < 0.05. Results: No significant differences were found between the groups in the asymmetries identified in the relevant anthropometric points, relative to the position assumed during the examination or to the subjects' sex. Conclusions: There are no significant differences in body posture in the coronal plane, between preterm children and full-term children. Premature birth does not have adverse effects related to body posture asymmetry in preterm children at the age of six. PMID- 29181409 TI - Therapy Effects of Wogonin on Ovarian Cancer Cells. AB - Background: Wogonin is a plant monoflavonoid and has been reported to induce apoptosis of cancer cells and show inhibitory effect on cancer cell growth. However, the detailed and underlying molecular mechanisms are not elucidated. In this study, we investigated the molecular and biological effects of wogonin in human ovarian A2780 cancer cells. Materials and Methods: We determined the effects of wogonin on the changes of cell cycling and apoptotic responses of cells. Western blot analysis was used to measure the effects of wogonin on protein expressions. Results: Our results showed that treatment with wogonin inhibited the cancer cell proliferation, decreased the percentage of G0/G1 subpopulation, and reduced invasiveness of A2780 cells. Exposure to wogonin also resulted in downregulated protein levels of estrogen receptor alpha (ER-alpha), VEGF, Bcl-2, and Akt and increased expressions of Bax and p53. In addition, exposure to wogonin increased caspase-3 cleavage and induced apoptosis in A2780 cells. Our study further showed that MPP, a specific ER-alpha inhibitor, significantly enhanced antitumor effects of wogonin in A2780 cells. Conclusion: Our results suggest a potential clinical impact of wogonin on management of ovarian cancer. PMID- 29181410 TI - The Anti-Inflammatory Activity of Toonaciliatin K against Adjuvant Arthritis. AB - Toonaciliatin K is a natural limonoid purified from the Toona ciliata Roem. var. ciliata (Meliaceae). This study is to reveal the inflammatory suppression effect of toonaciliatin K and further the intrinsic mechanism. Firstly, anti inflammatory effect of toonaciliatin K was evaluated in lipopolysaccharide- (LPS ) induced RAW264.7 cells. RT-PCR results indicated that the mRNA expressions of TNF-alpha, IL-6, and IL-1beta were downregulated by toonaciliatin K. The toonaciliatin K inhibited TNF-alpha, IL-6, and IL-1beta levels stimulated by LPS. Furthermore, LPS elicited the excess iNOS and COX-2 mRNA and protein production and toonaciliatin K attenuated the excess production. Western blot assay demonstrated that MAPK and NF-kappaB signaling pathways play critical roles in the toonaciliatin K's anti-inflammatory activity. Secondly, toonaciliatin K inhibited carrageenan-induced paw edema in rats. Thirdly, toonaciliatin K alleviated the paw swelling and improved arthritis clinical scores in the adjuvant arthritis rats. Toonaciliatin K decreased the proinflammatory cytokines levels and Mankin scores in adjuvant arthritis rats. The HE staining, safranin O fast green, and toluidine blue staining results demonstrated that toonaciliatin K alleviated the histological changes of paw, for example, pannus formation, focal loss of cartilage, bone erosion, and presence of extra-articular inflammation. Hence, toonaciliatin K is a promising agent for treatment of arthritis. PMID- 29181411 TI - RNA-seq Based Transcription Characterization of Fusion Breakpoints as a Potential Estimator for Its Oncogenic Potential. AB - Based on high-throughput sequencing technology, the detection of gene fusions is no longer a big challenge but estimating the oncogenic potential of fusion genes remains challenging. Recent studies successfully applied machine learning methods and gene structural and functional features of fusion mutation to predict their oncogenic potentials. However, the transcription characterizations features of fusion genes have not yet been studied. In this study, based on the clonal evolution theory, we hypothesized that a fusion gene is more likely to be an oncogenic genomic alteration, if the neoplastic cells harboring this fusion mutation have larger clonal size than other neoplastic cells in a tumor. We proposed a novel method, called iFCR (internal Fusion Clone Ratio), given an estimation of oncogenic potential for fusion mutations. We have evaluated the iFCR method in three public cancer transcriptome sequencing datasets; the results demonstrated that the fusion mutations occurring in tumor samples have higher internal fusion clone ratio than normal samples. And the most frequent prostate cancer fusion mutation, TMPRSS2-ERG, appears to have a remarkably higher iFCR value in all three independent patients. The preliminary results suggest that the internal fusion clone ratio might potentially advantage current fusion mutation oncogenic potential prediction methods. PMID- 29181413 TI - Comment on "Prevalence and Risk Factors for Diabetic Lower Limb Amputation: A Clinic-Based Case Control Study". PMID- 29181414 TI - High Fasting Plasma Glucose during Early Pregnancy: A Review about Early Gestational Diabetes Mellitus. AB - Fasting plasma glucose (FPG) is nowadays routinely measured during early pregnancy to detect preexisting diabetes (FPG >= 7 mmol/L). This screening has concomitantly led to identify early intermediate hyperglycemia, defined as FPG in the 5.1 to 6.9 mmol/L range, also early gestational diabetes mellitus (eGDM). Early FPG has been associated with poor pregnancy outcomes, but the recommendation by the IADPSG to refer women with eGDM for immediate management is more pragmatic than evidence based. Although eGDM is characterized by insulin resistance and associated with classical risk factors for type 2 diabetes and incident diabetes after delivery, it is not necessarily associated with preexisting prediabetes. FPG >= 5.1 mmol/L in early pregnancy is actually poorly predictive of gestational diabetes mellitus diagnosed after 24 weeks of gestation. An alternative threshold should be determined but may vary according to ethnicity, gestational age, and body mass index. Finally, observational data suggest that early management of intermediate hyperglycemia may improve prognosis, through reduced gestational weight gain and potential early introduction of hypoglycemic agents. Considering all these issues, we suggest an algorithm for the management of eGDM based on early FPG levels that would be measured in case of risk factors. Nevertheless, interventional randomized trials are still missing. PMID- 29181412 TI - Antioxidative Effects of Natural Products on Diabetic Cardiomyopathy. AB - Diabetic cardiomyopathy (DCM) is a common and severe complication of diabetes and results in high mortality. It is therefore imperative to develop novel therapeutics for the prevention or inhibition of the progression of DCM. Oxidative stress is a key mechanism by which diabetes induces DCM. Hence, targeting of oxidative stress-related processes in DCM could be a promising therapeutic strategy. To date, a number of studies have shown beneficial effects of several natural products on the attenuation of DCM via an antioxidative mechanism of action. The aim of the present review is to provide a comprehensive and concise overview of the previously reported antioxidant natural products in the inhibition of DCM progression. Clinical trials of the antioxidative natural products in the management of DCM are included. In addition, discussion and perspectives are further provided in the present review. PMID- 29181415 TI - Endothelial STAT3 Modulates Protective Mechanisms in a Mouse Ischemia-Reperfusion Model of Acute Kidney Injury. AB - STAT3 is a transcriptional regulator that plays an important role in coordinating inflammation and immunity. In addition, there is a growing appreciation of the role STAT3 signaling plays in response to organ injury following diverse insults. Acute kidney injury (AKI) from ischemia-reperfusion injury is a common clinical entity with devastating consequences, and the recognition that endothelial alterations contribute to kidney dysfunction in this setting is of growing interest. Consequently, we used a mouse with a genetic deletion of Stat3 restricted to the endothelium to examine the role of STAT3 signaling in the pathophysiology of ischemic AKI. In a mouse model of ischemic AKI, the loss of endothelial STAT3 signaling significantly exacerbated kidney dysfunction, morphologic injury, and proximal tubular oxidative stress. The increased severity of ischemic AKI was associated with more robust endothelial-leukocyte adhesion and increased tissue accumulation of F4/80+ macrophages. Moreover, important proximal tubular adaptive mechanisms to injury were diminished in association with decreased tissue mRNA levels of the epithelial cell survival cytokine IL-22. In aggregate, these findings suggest that the endothelial STAT3 signaling plays an important role in limiting kidney dysfunction in ischemic AKI and that selective pharmacologic activation of endothelial STAT3 signaling could serve as a potential therapeutic target. PMID- 29181416 TI - CD80 Expressed by CD8+ T Cells Contributes to PD-L1-Induced Apoptosis of Activated CD8+ T Cells. AB - Tumor cells are capable of limiting antitumor CD8+ T cell responses through their cell surface expression of PD-L1. In addition to PD-1 expressed by CD8+ T cells, PD-L1 also binds to CD80 expressed by CD8+ T cells. The influence of the PD L1/CD80 interaction on CD8+ T cell function has not been fully characterized, so we sought to investigate the impact of the PD-L1/CD80 interaction on PD-L1 induced apoptosis of activated CD8+ T cells. We found that CD8+ T cells that lacked CD80 expression got activated to the same extent as wild-type CD8+ T cells, but when cultured with anti-CD3 and PD-L1/Fc protein, activated CD8+ T cells that lacked CD80 expression survived better than activated wild-type CD8+ T cells. These findings indicate that PD-L1 induces apoptosis in activated CD8+ T cells in part by signaling through CD80. Thus, in the design and implementation of checkpoint blockade therapies that target PD-L1, it is essential that both binding partners for PD-L1, PD-1, and CD80 are considered. PMID- 29181417 TI - Toll-Like Receptor Ligand-Induced Liver Injury in D-Galactosamine-Sensitized Mice: Differences between TLR7/8 and TLR9 Ligands, Cytokine Patterns, and Cross Tolerance Induction by TLR2 Ligand Pretreatment. AB - Administration of Toll-like receptor ligands (TLRLs) is known to cause liver injury in D-galN-sensitized mice. In the present study, we aimed to complement preceding reports on the TLRL/D-galN system by analyzing comparisons among TLRLs, mouse strain dependence, effects on serum levels of cytokines, and effects of sequential administrations of different TLRLs. In a preliminary set of analyses, we first confirmed that liver failure can be induced by diverse TLRLs, including LTA and R848 in combination with D-galN. Analysis using TLR4-deficient mice excluded potential confounding effects of endogenous TLR4Ls that include those referred to as DAMPs in CpG DNA/D-galN hepatotoxicity. Subsequently, we showed that LTA pretreatment could prevent mortality in both CpG DNA/D-galN- and R848/D galN-treated mice compared to without pretreatment. Incidentally, we observed that without the LTA pretreatment, CpG DNA/D-galN showed relatively higher liver specific toxicity whereas R848/D-galN showed more symptoms of multiple organ failure. These findings suggest that, in D-galN-sensitized mice, different TLRLs not only show similarity in the ability to induce hepatic injury but also exhibit distinctive abilities in inducing systemic inflammation and multiple organ failure. These findings also suggest the potential usefulness of cross-tolerance induction using LTA in the prevention of organ failure in TLRL-mediated acute inflammation. PMID- 29181418 TI - Asymptomatic Cardiovascular Syphilis With Aortic Regurgitation Requiring Surgical Repair in an HIV-Infected Patient. AB - A 47-year-old man with HIV infection presented 10 years after initial secondary syphilis diagnosis and treatment for routine follow-up. His HIV was well controlled on antiretroviral therapy. Rapid plasma reagin was 1:1, and TP-PA was reactive. Physical examination revealed a wide pulse pressure, a systolic murmur, and an early diastolic decrescendo murmur. Echocardiogram revealed moderate to severe aortic regurgitation, and subsequent computed tomography angiogram showed a 6.8-cm fusiform aneurysm of the proximal ascending aorta. Aortic valve and ascending hemiarch replacement were performed. Pathology showed adventitial inflammation with plasma cells, gumma-like amorphous areas surrounded by histiocytes, and giant cells with calcified plaques. Cardiovascular syphilis, while rare, remains a relevant cause of aortic aneurysm, even in previously treated patients. The physical exam can be critical in identifying this potentially fatal complication. PMID- 29181419 TI - Decrease in Seminal HIV-1 RNA Load After Praziquantel Treatment of Urogenital Schistosomiasis Coinfection in HIV-Positive Men-An Observational Study. AB - Background: Urogenital schistosomiasis due to Schistosoma hematobium infection is hypothesized to cause increased HIV-1 RNA shedding in semen in HIV co-infected men as result of chronic egg-induced inflammation in the prostate and the seminal vesicles. The effect of treatment with the antihelminthic agent praziquantel on seminal HIV-1 RNA load was assessed in this study. Methods: HIV-1 RNA load was determined in blood plasma and semen at baseline and at 10-week follow-up. Praziquantel was administered at baseline and two weeks later. Results: Eighteen HIV-positive men with S. haematobium co-infection were enrolled into the study. Status of antiretroviral therapy (ART): 6 ART-naive and 12 ART-experienced. All participants became egg-negative in urine at follow-up. Among the ART-naive men, the mean HIV-1 RNA load decreased by 0.32 log10 copies per mL (4.41 vs 4.09) in blood plasma from baseline to follow-up, and in semen by 1.06 log10 copies per mL (4.06 vs 3.00). Conclusions: This study demonstrated a decline in seminal HIV-1 RNA load following praziquantel treatment of urogenital schistosomiasis infection in HIV-positive men. The finding needs further exploration in a larger randomized study targeting praziquantel as a supplementary preventive measure of sexual transmission of HIV-1 in S. haematobium endemic areas in sub-Saharan Africa.

PMID- 29181421 TI - Sociodemographic and Clinical Factors Associated With Increasing Bacterial Sexually Transmitted Infection Diagnoses in Men Who Have Sex With Men Accessing Care at a Boston Community Health Center (2005-2015). AB - Background: The reasons why bacterial sexually transmitted infections (BSTIs) are increasing in US men who have sex with men (MSM) have not been fully characterized. Methods: An open cohort of MSM accessing medical care at a Boston community health center was used to assess secular trends in BSTI diagnoses. Frequency of infection and the estimated population size were used to calculate diagnosis rates. Poisson models were fit for multivariable analyses. Results: Between 2005 and 2015, 19 232 men had at least 1 clinic visit. Most (72.4%) were white; 6.0% were black, and 6.1% were Latino. Almost half had documented self report of identifying as gay (42.6%) or bisexual (3.2%). Most had private health insurance (61.7%); 5.4% had Medicare, 4.6% had Medicaid, and 8.4% reported no insurance. Between 2005 and 2015, BSTI diagnoses increased more than 8-fold. In 2015, of 1319 men who were diagnosed with at least 1 BSTI; 291 were diagnosed with syphilis, 554 with gonorrhea (51.4% rectal, 31.0% urogenital), and 679 with chlamydia (69.1% rectal, 34.3% urogenital). In 2015, 22.7% of BSTIs were diagnosed among HIV-infected patients (15.4% of the clinic population), and 32.8% of BSTIs were diagnosed among HIV-uninfected patients using pre-exposure prophylaxis (PrEP; 10.1% of all men in care). In multivariable analyses, age 18 to 24 years, being HIV-infected, using PrEP, being nonwhite, or reporting Medicaid or not reporting having private insurance or Medicare were independently associated with being diagnosed with a new BSTI. Conclusions: Over the past decade, BSTI diagnosis rates increased in HIV-infected and uninfected MSM, with disproportionate increases in PrEP users, racial and ethnic minority MSM, those aged 25 to 34 years, and those without stable health insurance, warranting focused education, screening, and accessible services for these key subpopulations.

PMID- 29181422 TI - Carbapenem-Resistant Enterobacteriaceae Infections in Patients on Renal Replacement Therapy. AB - Background: Patients on chronic intermittent renal replacement therapy (RRT) are at risk for infection with carbapenem-resistant Enterobacteriaceae (CRE). However, the impact of RRT on outcomes after CRE infections remains to be defined. Here we perform a comparison of outcomes for CRE-infected patients with preserved renal function compared with CRE-infected patients on RRT. Methods: Cases and controls were defined from a prospective cohort of CRE-infected patients from the Consortium on Resistance against Carbapenems in Klebsiella and other Enterobacteriaceae (CRACKLE). Cases were defined as CRE-infected patients on RRT at hospital admission, while controls were defined as CRE-infected patients with serum creatinine <2 mg/dL and not receiving RRT at admission. Risk factors for 28-day in-hospital mortality were assessed using multivariable logistic regression. An ordinal ranking of outcomes by desirability analysis was performed. Results: Patients on RRT were more likely to have diabetes mellitus and cardiac disease than controls. Urinary sources of infection were less common in the RRT group. In RRT patients, 28-day in-hospital mortality was increased as compared with controls: 22/71 (31%) vs 33/295 (11%). RRT remained significantly associated with 28-day in-hospital mortality after adjustment for source of infection, prehospitalization origin, and severity of illness (adjusted odds ratio, 2.27; 95% confidence interval [CI], 1.09-4.68; P = .03). Using univariable desirability of outcome ranking analysis, RRT status was associated with a 68% (95% CI, 61%-74%) chance of a worse disposition outcome. Conclusions: Chronic RRT in CRE-infected patients is associated with increased in-hospital mortality and worse disposition outcomes at 28 days.

AB - Background: Perinatal transmission is the main route of hepatitis B virus (HBV) transmission. While several measures have been attempted as means of preventing perinatal HBV transmission, the optimal strategy remains inconclusive. Methods: We conducted a comprehensive search, through December 2016, for randomized controlled trials (RCTs) that compared the following measures among pregnant women with HBV infection: placebo/none, active immunoprophylaxis (hepatitis B vaccine series starting at birth [HBVac]), passive-active immunoprophylaxis (hepatitis B immunoglobulin and vaccine [HBIG+HBVac]), prenatal HBIG administration (HBIG/HBIG+HBVac), and prenatal antiviral therapy (AVT/HBIG+HBVac). Direct, indirect, and network meta-analyses were performed for all treatment comparisons. Results: Fifteen RCTs involving 2706 infants of HBV carrier mothers were eligible for analysis. Network meta-analysis demonstrated similar results as direct and indirect comparisons. HBVac alone significantly reduced the risk of hepatitis B infection in infants of HBV carrier mothers (relative risk [RR], 0.32; 95% confidence interval [CI], 0.21-0.50). The combination of immunoglobulin with vaccine is superior to vaccine alone (RR, 0.37; 95% CI, 0.20-0.67). Prenatal HBIG administration and antiviral therapy offer further advantages over current passive-active immunoprophylaxis for infants of highly viremic (HBV DNA level higher than 2 * 105 IU/mL) mothers (RR, 0.47; 95% CI, 0.29-0.75; and RR, 0.31; 95% CI, 0.10-0.99, respectively). There was no significant publication bias. Conclusions: Based on the universal infantile vaccination program, HBIG for infants born to HBV carrier mothers further reduces transmission. For highly viremic mothers whose children are still at risk for transmission under current immunoprophylaxis, prenatal HBIG administration or antiviral therapy in late pregnancy may be considered if more long-term evidence supports its efficacy and safety.

AB - Capitalizing on endogenous hemoglobin contrast, photoacoustic-computed tomography (PACT), a deep-tissue high-resolution imaging modality, has drawn increasing interest in neuroimaging. However, most existing studies are limited to functional imaging on the cortical surface and the deep brain structural imaging capability of PACT has never been demonstrated. Here, we explicitly studied the limiting factors of deep brain PACT imaging. We found that the skull distorted the acoustic signal and blood suppressed the structural contrast from other chromophores. When the two effects are mitigated, PACT can potentially provide high-resolution label-free imaging of structures in the entire mouse brain. With [Formula: see text] in-plane resolution, we can clearly identify major structures of the brain, which complements magnetic resonance microscopy for imaging small animal brain structures. Spectral PACT studies indicate that structural contrasts mainly originate from cytochrome distribution and that the presence of lipid sharpens the image contrast; brain histology results provide further validation. The feasibility of imaging the structure of the brain in vivo is also discussed. Our results demonstrate that PACT is a promising modality for both structural and functional brain imaging. PMID- 29181426 TI - Mitochondrial matrix pH as a decisive factor in neurometabolic imaging. AB - Alterations of cellular bioenergetics are a common feature in most neurodegenerative disorders. However, there is a selective vulnerability of different brain regions, cell types, and even mitochondrial populations to these metabolic disturbances. Thus, the aim of our study was to establish and validate an in vivo metabolic imaging technique to screen for mitochondrial function on the subcellular level. Based on nicotinamide adenine dinucleotide (phosphate) fluorescence lifetime imaging microscopy [NAD(P)H FLIM], we performed a quantitative correlation to high-resolution respirometry. Thereby, we revealed mitochondrial matrix pH as a decisive factor in imaging NAD(P)H redox state. By combining both parameters, we illustrate a quantitative, high-resolution assessment of mitochondrial function in metabolically modified cells as well as in an amyloid precursor protein-overexpressing model of Alzheimer's disease. Our metabolic imaging technique provides the basis for dissecting mitochondrial deficits not only in a range of neurodegenerative diseases, shedding light onto bioenergetic failures of cells remaining in their metabolic microenvironment. PMID- 29181428 TI - Pulmonary nodule classification in lung cancer screening with three-dimensional convolutional neural networks. AB - A three-dimensional (3-D) convolutional neural network (CNN) trained from scratch is presented for the classification of pulmonary nodule malignancy from low-dose chest CT scans. Recent approval of lung cancer screening in the United States provides motivation for determining the likelihood of malignancy of pulmonary nodules from the initial CT scan finding to minimize the number of follow-up actions. Classifier ensembles of different combinations of the 3-D CNN and traditional machine learning models based on handcrafted 3-D image features are also explored. The dataset consisting of 326 nodules is constructed with balanced size and class distribution with the malignancy status pathologically confirmed. The results show that both the 3-D CNN single model and the ensemble models with 3-D CNN outperform the respective counterparts constructed using only traditional models. Moreover, complementary information can be learned by the 3-D CNN and the conventional models, which together are combined to construct an ensemble model with statistically superior performance compared with the single traditional model. The performance of the 3-D CNN model demonstrates the potential for improving the lung cancer screening follow-up protocol, which currently mainly depends on the nodule size. PMID- 29181427 TI - Effect of short-term colored-light exposure on cerebral hemodynamics and oxygenation, and systemic physiological activity. AB - There is not yet a comprehensive view of how the color of light affects the cerebral and systemic physiology in humans. The aim was to address this deficit through basic research. Since cerebral and systemic physiological parameters are likely to interact, it was necessary to establish an approach, which we have termed "systemic-physiology-augmented functional near-infrared spectroscopy (SPA fNIRS) neuroimaging." This multimodal approach measures the systemic and cerebral physiological response to exposure to light of different colors. In 14 healthy subjects (9 men, 5 women, age: [Formula: see text] years, range: 24 to 57 years) exposed to red, green, and blue light (10-min intermittent wide-field visual color stimulation; [Formula: see text] blocks of visual stimulation), brain hemodynamics and oxygenation were measured by fNIRS on the prefrontal cortex (PFC) and visual cortex (VC) simultaneously, in addition with systemic parameters. This study demonstrated that (i) all colors elicited responses in the VC, whereas only blue evoked a response in the PFC; (ii) there was a color dependent effect on cardiorespiratory activity; (iii) there was significant change in neurosystemic functional connectivity; (iv) cerebral hemodynamic responses in the PFC and changes in the cardiovascular system were gender and age dependent; and (v) electrodermal activity and psychological state showed no stimulus-evoked changes, and there was no dependence on color of light, age, and gender. We showed that short-term light exposure caused color-dependent responses in cerebral hemodynamics/oxygenation as well as cardiorespiratory dynamics. Additionally, we showed that neurosystemic functional connectivity changes even during apparently stress-free tasks-an important consideration when using any of the hemodynamic neuroimaging methods (e.g. functional magnetic resonance imaging, positron emission tomography, and fNIRS). Our findings are important for future basic research and clinical applications as well as being relevant for everyday life. PMID- 29181429 TI - Lung nodule volume quantification and shape differentiation with an ultra-high resolution technique on a photon-counting detector computed tomography system. AB - An ultra-high resolution (UHR) mode, with a detector pixel size of [Formula: see text] relative to isocenter, has been implemented on a whole body research photon counting detector (PCD) computed tomography (CT) system. Twenty synthetic lung nodules were scanned using UHR and conventional resolution (macro) modes and reconstructed with medium and very sharp kernels. Linear regression was used to compare measured nodule volumes from CT images to reference volumes. The full width-at-half-maximum of the calculated curvature histogram for each nodule was used as a shape index, and receiver operating characteristic analysis was performed to differentiate sphere- and star-shaped nodules. Results showed a strong linear relationship between measured nodule volumes and reference volumes for both modes. The overall volume estimation was more accurate using UHR mode and the very sharp kernel, having 4.8% error compared with 10.5% to 12.6% error in the macro mode. The improvement in volume measurements using the UHR mode was more evident for small nodule sizes or star-shaped nodules. Images from the UHR mode with the very sharp kernel consistently demonstrated the best performance [[Formula: see text]] for separating star- from sphere-shaped nodules, showing advantages of UHR mode on a PCD CT scanner for lung nodule characterization. PMID- 29181430 TI - Automatic selection of landmarks in T1-weighted head MRI with regression forests for image registration initialization. AB - Medical image registration establishes a correspondence between images of biological structures, and it is at the core of many applications. Commonly used deformable image registration methods depend on a good preregistration initialization. We develop a learning-based method to automatically find a set of robust landmarks in three-dimensional MR image volumes of the head. These landmarks are then used to compute a thin plate spline-based initialization transformation. The process involves two steps: (1) identifying a set of landmarks that can be reliably localized in the images and (2) selecting among them the subset that leads to a good initial transformation. To validate our method, we use it to initialize five well-established deformable registration algorithms that are subsequently used to register an atlas to MR images of the head. We compare our proposed initialization method with a standard approach that involves estimating an affine transformation with an intensity-based approach. We show that for all five registration algorithms the final registration results are statistically better when they are initialized with the method that we propose than when a standard approach is used. The technique that we propose is generic and could be used to initialize nonrigid registration algorithms for other applications. PMID- 29181431 TI - Neovascularization detection in diabetic retinopathy from fluorescein angiograms. AB - Although a lot of work has been done on optical coherence tomography and color images in order to detect and quantify diseases such as diabetic retinopathy, exudates, or neovascularizations, none of them is able to evaluate the diffusion of the neovascularizations in retinas. Our work has been to develop a tool that is able to quantify a neovascularization and the fluorescein leakage during an angiography. The proposed method has been developed following a clinical trial protocol; images are taken by a Spectralis (Heidelberg Engineering). Detections are done using a supervised classification using specific features. Images and their detected neovascularizations are then spatially matched by an image registration. We compute the expansion speed of the liquid that we call diffusion index. This last one specifies the state of the disease, permits indication of the activity of neovascularizations, and allows a follow-up of patients. The method proposed in this paper has been built to be robust, even with laser impacts, to compute a diffusion index. PMID- 29181432 TI - Cochlear implant phantom for evaluating computed tomography acquisition parameters. AB - Cochlear implants (CIs) are surgically implantable neuroprosthetic devices used to treat profound hearing loss. Recent literature indicates that there is a correlation between the final intracochlear positioning of the CI electrode arrays and the ultimate hearing outcome of the patient, indicating that further studies to better understand the relationship between electrode position and outcomes could have significant implications for future surgical techniques, array design, and processor programming methods. Postimplantation high-resolution computed tomography (CT) imaging is the best modality for localizing electrodes and provides the resolution necessary to visually identify electrode position, although with an unknown degree of accuracy depending on image acquisition parameters, like the hounsfield unit (HU) range of reconstruction, orientation, radiation dose, and image resolution. We report on the development of a phantom and on its use to study how four acquisition parameters, including image resolution and HU range of reconstruction, affect how accurately the true position of the electrodes can be found in a dataset of CT scans acquired from multiple helical and cone beam scanners. We also show how the phantom can be used to evaluate the effect of acquisition parameters on automatic electrode localization techniques. PMID- 29181433 TI - Tumor image signatures and habitats: a processing pipeline of multimodality metabolic and physiological images. AB - To create tumor "habitats" from the "signatures" discovered from multimodality metabolic and physiological images, we developed a framework of a processing pipeline. The processing pipeline consists of six major steps: (1) creating superpixels as a spatial unit in a tumor volume; (2) forming a data matrix [Formula: see text] containing all multimodality image parameters at superpixels; (3) forming and clustering a covariance or correlation matrix [Formula: see text] of the image parameters to discover major image "signatures;" (4) clustering the superpixels and organizing the parameter order of the [Formula: see text] matrix according to the one found in step 3; (5) creating "habitats" in the image space from the superpixels associated with the "signatures;" and (6) pooling and clustering a matrix consisting of correlation coefficients of each pair of image parameters from all patients to discover subgroup patterns of the tumors. The pipeline was applied to a dataset of multimodality images in glioblastoma (GBM) first, which consisted of 10 image parameters. Three major image "signatures" were identified. The three major "habitats" plus their overlaps were created. To test generalizability of the processing pipeline, a second image dataset from GBM, acquired on the scanners different from the first one, was processed. Also, to demonstrate the clinical association of image-defined "signatures" and "habitats," the patterns of recurrence of the patients were analyzed together with image parameters acquired prechemoradiation therapy. An association of the recurrence patterns with image-defined "signatures" and "habitats" was revealed. These image-defined "signatures" and "habitats" can be used to guide stereotactic tissue biopsy for genetic and mutation status analysis and to analyze for prediction of treatment outcomes, e.g., patterns of failure. PMID- 29181434 TI - Androgen receptor (AR) cistrome in prostate differentiation and cancer progression. AB - Despite the progress in development of better AR-targeted therapies for prostate cancer (PCa), there is no curative therapy for castration-resistant prostate cancer (CRPC). Therapeutic resistance in PCa can be characterized in two broad categories of AR therapy resistance: the first and most prevalent one involves restoration of AR activity despite AR targeted therapy, and the second one involves tumor progression despite blockade of AR activity. As such AR remains the most attractive drug target for CRPC. Despite its oncogenic role, AR signaling also contributes to the maturation and differentiation of prostate luminal cells during development. Recent evidence suggests that AR cistrome is altered in advanced PCa. Alteration in AR may result from AR amplification, alternative splicing, mutations, post-translational modification of AR, and altered expression of AR co-factors. We reasoned that such alterations would result in the transcription of disparate AR target genes and as such may contribute to the emergence of castration-resistance. In the present study, we evaluated the expression of genes associated with canonical or non-canonical AR cistrome in relationship with PCa progression and prostate development by analyzing publicly available datasets. We discovered a transcription switch from canonical AR cistrome target genes to the non-canonical AR cistrome target genes during PCa progression. Using Gene Set Enrichment Analysis (GSEA), we discovered that canonical AR cistrome target genes are enriched in indolent PCa patients and the loss of canonical AR cistrome is associated with tumor metastasis and poor clinical outcome. Analysis of the datasets involving prostate development, revealed that canonical AR cistrome target genes are significantly enriched in prostate luminal cells and can distinguish luminal cells from basal cells, suggesting a pivotal role for canonical AR cistrome driven genes in prostate development. These data suggest that the expression of canonical AR cistrome related genes play an important role in maintaining the prostate luminal cell identity and might restrict the lineage plasticity observed in lethal PCa. Understanding the molecular mechanisms that dictate AR cistrome may lead to development of new therapeutic strategies aimed at restoring canonical AR cistrome, rewiring the oncogenic AR signaling and overcome resistance to AR targeted therapies. PMID- 29181435 TI - Organoid culture of human prostate cancer cell lines LNCaP and C4-2B. AB - Organoids mimic the architecture and functions of a small organ. Organoid culture technique has been rapidly accepted by all research communities during the past decade to study stem cells, organ development and function, and patient-specific diseases. A protocol for organoid culture of human and mouse prostate epithelial and cancer tissues has been reported. However, organoid culture of the commonly used human prostate cancer cell lines has yet to be established. We followed the published protocol and performed organoid culture of LNCaP and C4-2B cells in MatrigelTM and organoid culture medium for 14 days. We found that both LNCaP and C4-2B cell lines formed organoids that presented glandular structures. The cells within the organoids were androgen receptor-positive adenocarcinoma cells, but not p63-positive basal cells. The cells in the organoids responded to interleukin 17A treatment differently from the cells in the monolayer culture. The present study suggests that LNCaP and C4-2B cells are able to form organoids under the defined organoid culture conditions. PMID- 29181437 TI - Clinical features of patients treated by peritoneal dialysis for over a decade. AB - BACKGROUND: Peritoneal dialysis (PD) is well-established as renal replacement therapy in end stage renal disease and has survival rates similar or better than hemodialysis (HD) for the initial years on dialysis therapy. However retention rate is lower due to higher technique failure rates than in HD and few patients stay on PD for more than 10 years (PD>10 yrs). Here we investigated clinical features characterizing PD>10 yrs patients. PATIENTS AND METHODS: In a single center study of 450 prevalent PD patients, 35 PD>10 yrs patients (n=35) were compared with patients (n=415) who had been on PD for shorter periods of time in terms of clinical characteristics. Peritoneal transport, blood pressure, solute clearance, nutrition status, and blood calcium, phosphate and parathyroid hormone levels were measured dialysis start and, in PD>10 yrs patients, also after 5 and 10 years of PD. RESULTS: The PD>10 yrs patients differed from the other PD patients in that (1) the proportion of women was higher; (2) body mass index (BMI) was lower; (3) there was no patient with diabetic nephropathy as primary diagnosis; (4) the incidence of peritonitis was lower; (5) glomerular filtration rate was higher; and (6) parathyroid hormone (PTH) levels were lower in those with decade-long PD treatment. In PD>10 yrs patients, serum albumin was maintained at a high level throughout the 10 year follow up; hemoglobin levels after 5 and 10 years of PD were higher than at the beginning of the treatment; blood calcium and phosphate concentrations were maintained at acceptable levels; while the dialysate/plasma ratio of creatinine, D/P-value, increased during the decade-long PD treatment. CONCLUSIONS: Patients receiving PD>10 years had lower incidence of peritonitis, lower BMI, adequate control of blood calcium and phosphate levels and solute clearance, and were more often women than PD patients treated for shorter periods of time. PMID- 29181438 TI - Parsley! Mechanism as antiurolithiasis remedy. AB - Parsley is a medicinal plant used widely in urolithiasis. The present study aimed to evaluate the antiurolithiatic effect of parsley and its mechanism. 24 rats divided into four groups: group A (negative control), group B (positive control), group C (cystone(r) group) and group D (parsley group). Group B were treated with EG and Ammonium chloride (AC). Group C were treated as B plus cystone(r) and group D was treated as B plus parsley. The period of experiment was 15 days. Urine samples were analysis on days 0 and 15 days. Kidneys of rats from all groups were removed, and histopathologically examined. The kidnies of parsley treated group appeared mostly to be calculi-free (less CaOx) even better than the cystone treated group. CaOx crystals was significantly lower both in histological sections and in urine samples in parsley treated group. We further investigated the mechanism of parsley by adding another 6 rats. The latter treated by parsley only after adaptation period. We found significant increase in urine volume and pH in parsley treated rats compared to negative control. We concluded that parsley acts as antiurolithiatic drug through decreasing urinary calcium excretion, increasing urinary pH, dieresis, decreasing urinary protein excretion and its nephroprtective activity. We recommended to use it in pharmaceutical forms as it is safe and effective as antiurolithiasis remedy. PMID- 29181436 TI - Molecular mechanisms involving prostate cancer racial disparity. AB - Prostate cancer (PCa) is the second leading cause of cancer-related deaths in the United States. The African (AA) descent has greater incidence and mortality rates of PCa as compared to Caucasian (CA) men. While socioeconomic differences across racial groups contribute to disparity in PCa, increasing evidence points that genetic and molecular alterations play important roles in racial disparities associated with PCa. In this review, we focus on genetic and molecular influences that contribute to racial disparity between AA and CA men including: androgen and estrogen receptor signaling pathways, growth factors, apoptotic proteins, genetic, genomic and epigenetic alterations. Future translational studies will identify prognostic and predictive biomarkers for AA PCa and assist in the development of new targeted-therapies specifically for AA men with PCa. PMID- 29181439 TI - Rest-activity circadian rhythms and bone mineral density in elderly men. AB - Background: Disrupted rest-activity circadian rhythm (RAR) patterns have been associated with poor health outcomes (i.e. diminished cognitive function, increased risk of dementia and falls). Circadian time cues in bone influence the differentiation of osteoblasts and osteoclasts, and bone turnover markers exhibit circadian variation; relationships between bone outcomes and RAR are emerging areas of research. We evaluated associations between RAR and areal bone mineral density (aBMD) at the total hip and femoral neck in older men from the Osteoporotic Fractures in Men (MrOS) cohort. We hypothesized that weaker RAR patterns would be associated with lower aBMD. Methods: MrOS is an ongoing prospective cohort study following ambulatory men >= 65 years (n = 5994) at 6 U.S. clinics (baseline enrollment 3/2000-4/2002); participants for this analysis are from an ancillary study, Outcomes of Sleep Disorders in Older Men (MrOS Sleep). We included data from men who had technically adequate measures of RAR and aBMD at Sleep Visit 1 (12/2003-3/2005), with repeat aBMD at core Visit 3 (3/2007-3/2009) (n = 2412; mean age at Sleep Visit 1: 75.7 +/- 5.2 years). aBMD was measured by dual energy x-ray absorptiometry (DXA). Actigraphs worn on the non-dominant wrist were used to collect circadian activity data over 4.8 +/- 0.8 consecutive 24-hour periods. An extension of the traditional cosine curve was used to fit RAR to the activity data [Ancoli-Israel et al., 2003; Marler et al., 2006]. Six RAR parameters were evaluated: acrophase (time of peak activity), amplitude (rhythm strength), mesor (mean of activity fitted curve), pseudo F statistic (overall circadian rhythmicity of rest and activity), alpha statistic (daytime to nighttime activity ratio), and beta statistic (daytime activity). Associations between RAR and aBMD (Sleep Visit 1), and RAR and DeltaaBMD (Sleep Visit 1-Visit 3) were assessed with generalized linear models. Covariates included age, clinic site, physical activity, race, comorbidity, body mass index (BMI), smoking, alcohol, caffeine, beta blocker use, serum 25(OH) vitamin D and urinary melatonin and calcium. Results: Pseudo F-statistic was significantly associated with total hip aBMD (p-trend = 0.009), femoral neck aBMD (p-trend = 0.007) and total hip DeltaaBMD (p-trend = 0.017) in minimally adjusted models but not after multivariate (MV) adjustment. Alpha statistic was significantly associated with femoral neck aBMD (p-trend = 0.029) and femoral neck DeltaaBMD (p trend = 0.019) in minimally adjusted models; significance was retained in the femoral neck DeltaaBMD model (p-trend = 0.034) after MV adjustment. There were no consistent, significant associations between the other RAR variables and aBMD or DeltaaBMD. Conclusions: The data demonstrate modest associations between overall circadian rhythmicity of rest and activity (measured by pseudo F-statistic), as well as daytime to nighttime activity ratio (measured by alpha statistic), aBMD and DeltaaBMD, but adjustment for covariates related to lifestyle, BMI and comorbidities attenuated most of these associations. These results suggest that RAR patterns are not independently associated with aBMD or four-year DeltaaBMD at the total hip or femoral neck in older men, but additional research is needed. PMID- 29181440 TI - Influence of Dexamethasone on Some Reproductive Hormones and Uterine Progesterone Receptor Localization in Pregnant Yankasa Sheep in Semiarid Zones of Nigeria. AB - Dexamethasone is widely used in both veterinary and human medical practices. However, it seems to cause some deleterious effects on pregnancy probably by causing changes in the reproductive hormone levels and their corresponding receptor concentrations. This study investigated the effects of dexamethasone on these parameters. Twenty healthy adult Yankasa sheep comprising 18 ewes and 2 rams were used for this study. Pregnancies were achieved by natural mating after estrus synchronization. Dexamethasone was administered at 0.25 mg/kg body weight on days 1, 3, and 5 during first trimester; days 51, 53, and 55 during second trimester; and days 101, 103, and 105 during the third trimester. Blood samples were collected biweekly for hormonal assay. Uterine biopsies were harvested through caesarean section for immunohistochemical analysis. Results showed that dexamethasone significantly (p < 0.05) decreased progesterone concentrations and caused abortion in Yankasa sheep but had no significant (p > 0.05) effect on estrogen, while progesterone receptors (PR) were upregulated. The abortion could probably be due to decreased progesterone concentrations as a consequence of the adverse effects on placenta. The PR upregulation may be a compensatory mechanism to increase progesterone sensitivity. It was concluded that dexamethasone should not be used in advanced pregnancy in Yankasa sheep. PMID- 29181441 TI - The Severity of Retinopathy in the Extremely Premature Infants. AB - Objective: We aimed to investigate the incidence and the severity of retinopathy of extremely premature infants and to evaluate the risk factors and outcome of the cases. Materials and Methods: Out of 200 premature births, we retrospectively reviewed 9 cases that developed ROP. We excluded cases where ROP developed in newborns > 30 weeks of gestational age and cases where medical notes were unavailable or incomplete. Topical drops of cyclopentolate 1% and phenylephrine 5% were instilled and fundoscopy was performed using a direct ophthalmoscope. Results: The incidence of ROP was 4.5% in the 9-year period. The infants were divided into two groups. Group 1 included premature infants <=27 weeks of age and Group 2 included those >27 weeks but <= 30 weeks of age. We found that the infants of Group 1 showed advanced stages of ROP in comparison to Group 2. Out of 18 eyes, 11 eyes had stage 3 ROP and they were all found in Group 1 (100% of cases). Conclusion: The severity of ROP was associated with earlier gestational age, lower birth weight, and oxygen supplementation. Constant cooperation between physicians and nursing staff is necessary to avoid undetected cases and further prevent ROP related blindness. PMID- 29181442 TI - Weak Middle-Ear-Muscle Reflex in Humans with Noise-Induced Tinnitus and Normal Hearing May Reflect Cochlear Synaptopathy. AB - Chronic tinnitus is a prevalent hearing disorder, and yet no successful treatments or objective diagnostic tests are currently available. The aim of this study was to investigate the relationship between the presence of tinnitus and the strength of the middle-ear-muscle reflex (MEMR) in humans with normal and near-normal hearing. Clicks were used as test stimuli to obtain a wideband measure of the effect of reflex activation on ear-canal sound pressure. The reflex was elicited using a contralateral broadband noise. The results show that the reflex strength is significantly reduced in individuals with noise-induced continuous tinnitus and normal or near-normal audiometric thresholds compared with no-tinnitus controls. Due to a shallower growth of the reflex strength in the tinnitus group, the difference between the two groups increased with increasing elicitor level. No significant difference in the effect of tinnitus on the strength of the middle-ear muscle reflex was found between males and females. The weaker reflex could not be accounted for by differences in audiometric hearing thresholds between the tinnitus and control groups. Similarity between our findings in humans and the findings of a reduced middle-ear muscle reflex in noise-exposed animals suggests that noise-induced tinnitus in individuals with clinically normal hearing may be a consequence of cochlear synaptopathy, a loss of synaptic connections between inner hair cells (IHCs) in the cochlea and auditory-nerve (AN) fibers that has been termed hidden hearing loss. PMID- 29181443 TI - Networks of global bird invasion altered by regional trade ban. AB - Wildlife trade is a major pathway for introduction of invasive species worldwide. However, how exactly wildlife trade influences invasion risk, beyond the transportation of individuals to novel areas, remains unknown. We analyze the global trade network of wild-caught birds from 1995 to 2011 as reported by CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora). We found that before the European Union ban on imports of wild-caught birds, declared in 2005, invasion risk was closely associated with numbers of imported birds, diversity of import sources, and degree of network centrality of importer countries. After the ban, fluxes of global bird trade declined sharply. However, new trade routes emerged, primarily toward the Nearctic, Afrotropical, and Indo-Malay regions. Although regional bans can curtail invasion risk globally, to be fully effective and prevent rerouting of trade flows, bans should be global. PMID- 29181444 TI - Climate change and water management in the biblical city of Dan. AB - Global climate change has sharpened focus on the social and economic challenges associated with water deficits, particularly in regions where anthropogenic demands exceed supply. This modern condition was also experienced by the people of ancient western Asia, where chronic water shortages were accentuated by recurrent droughts. However, human societies may react to climate change, particularly desiccation, in different ways depending on specific local conditions. Focusing on the biblical site of Tel Dan (present-day Israel), we show the effects of severe precipitation decline in an environment that was well watered and fertile even in times of drought. Such local niches of prosperity became attractive targets for predation when food resources became scarce in surrounding rain-fed areas. We propose that predation forced urban populations to either flee or adopt new subsistence strategies. Predation and abandonment, even if only partial, led to the poor maintenance of water networks in and around the city. Once stagnant water surrounded the area, water-borne disease proliferated. Our study shows how climate changes can disrupt social and political structures, cause water system management to collapse, and facilitate marshland expansion. PMID- 29181445 TI - Artificially lit surface of Earth at night increasing in radiance and extent. AB - A central aim of the "lighting revolution" (the transition to solid-state lighting technology) is decreased energy consumption. This could be undermined by a rebound effect of increased use in response to lowered cost of light. We use the first-ever calibrated satellite radiometer designed for night lights to show that from 2012 to 2016, Earth's artificially lit outdoor area grew by 2.2% per year, with a total radiance growth of 1.8% per year. Continuously lit areas brightened at a rate of 2.2% per year. Large differences in national growth rates were observed, with lighting remaining stable or decreasing in only a few countries. These data are not consistent with global scale energy reductions but rather indicate increased light pollution, with corresponding negative consequences for flora, fauna, and human well-being. PMID- 29181446 TI - Discrete False-Discovery Rate Improves Identification of Differentially Abundant Microbes. AB - Differential abundance testing is a critical task in microbiome studies that is complicated by the sparsity of data matrices. Here we adapt for microbiome studies a solution from the field of gene expression analysis to produce a new method, discrete false-discovery rate (DS-FDR), that greatly improves the power to detect differential taxa by exploiting the discreteness of the data. Additionally, DS-FDR is relatively robust to the number of noninformative features, and thus removes the problem of filtering taxonomy tables by an arbitrary abundance threshold. We show by using a combination of simulations and reanalysis of nine real-world microbiome data sets that this new method outperforms existing methods at the differential abundance testing task, producing a false-discovery rate that is up to threefold more accurate, and halves the number of samples required to find a given difference (thus increasing the efficiency of microbiome experiments considerably). We therefore expect DS FDR to be widely applied in microbiome studies. IMPORTANCE DS-FDR can achieve higher statistical power to detect significant findings in sparse and noisy microbiome data compared to the commonly used Benjamini-Hochberg procedure and other FDR-controlling procedures. PMID- 29181447 TI - Increased Biosynthetic Gene Dosage in a Genome-Reduced Defensive Bacterial Symbiont. AB - A symbiotic lifestyle frequently results in genome reduction in bacteria; the isolation of small populations promotes genetic drift and the fixation of deletions and deleterious mutations over time. Transitions in lifestyle, including host restriction or adaptation to an intracellular habitat, are thought to precipitate a wave of sequence degradation events and consequent proliferation of pseudogenes. We describe here a verrucomicrobial symbiont of the tunicate Lissoclinum sp. that appears to be undergoing such a transition, with low coding density and many identifiable pseudogenes. However, despite the overall drive toward genome reduction, this symbiont maintains seven copies of a large polyketide synthase (PKS) pathway for the mandelalides (mnd), cytotoxic compounds that likely constitute a chemical defense for the host. There is evidence of ongoing degradation in a small number of these repeats-including variable borders, internal deletions, and single nucleotide polymorphisms (SNPs). However, the gene dosage of most of the pathway is increased at least 5-fold. Correspondingly, this single pathway accounts for 19% of the genome by length and 25.8% of the coding capacity. This increased gene dosage in the face of generalized sequence degradation and genome reduction suggests that mnd genes are under strong purifying selection and are important to the symbiotic relationship. IMPORTANCE Secondary metabolites, which are small-molecule organic compounds produced by living organisms, provide or inspire drugs for many different diseases. These natural products have evolved over millions of years to provide a survival benefit to the producing organism and often display potent biological activity with important therapeutic applications. For instance, defensive compounds in the environment may be cytotoxic to eukaryotic cells, a property exploitable for cancer treatment. Here, we describe the genome of an uncultured symbiotic bacterium that makes such a cytotoxic metabolite. This symbiont is losing genes that do not endow a selective advantage in a hospitable host environment. Secondary metabolism genes, however, are repeated multiple times in the genome, directly demonstrating their selective advantage. This finding shows the strength of selective forces in symbiotic relationships and suggests that uncultured bacteria in such relationships should be targeted for drug discovery efforts. PMID- 29181448 TI - Direct PCR Offers a Fast and Reliable Alternative to Conventional DNA Isolation Methods for Gut Microbiomes. AB - The gut microbiome of animals is emerging as an important factor influencing ecological and evolutionary processes. A major bottleneck in obtaining microbiome data from large numbers of samples is the time-consuming laboratory procedures required, specifically the isolation of DNA and generation of amplicon libraries. Recently, direct PCR kits have been developed that circumvent conventional DNA extraction steps, thereby streamlining the laboratory process by reducing preparation time and costs. However, the reliability and efficacy of direct PCR for measuring host microbiomes have not yet been investigated other than in humans with 454 sequencing. Here, we conduct a comprehensive evaluation of the microbial communities obtained with direct PCR and the widely used Mo Bio PowerSoil DNA extraction kit in five distinct gut sample types (ileum, cecum, colon, feces, and cloaca) from 20 juvenile ostriches, using 16S rRNA Illumina MiSeq sequencing. We found that direct PCR was highly comparable over a range of measures to the DNA extraction method in cecal, colon, and fecal samples. However, the two methods significantly differed in samples with comparably low bacterial biomass: cloacal and especially ileal samples. We also sequenced 100 replicate sample pairs to evaluate repeatability during both extraction and PCR stages and found that both methods were highly consistent for cecal, colon, and fecal samples (rs > 0.7) but had low repeatability for cloacal (rs = 0.39) and ileal (rs = -0.24) samples. This study indicates that direct PCR provides a fast, cheap, and reliable alternative to conventional DNA extraction methods for retrieving 16S rRNA data, which can aid future gut microbiome studies. IMPORTANCE The microbial communities of animals can have large impacts on their hosts, and the number of studies using high-throughput sequencing to measure gut microbiomes is rapidly increasing. However, the library preparation procedure in microbiome research is both costly and time-consuming, especially for large numbers of samples. We investigated a cheaper and faster direct PCR method designed to bypass the DNA isolation steps during 16S rRNA library preparation and compared it with a standard DNA extraction method. We used both techniques on five different gut sample types collected from 20 juvenile ostriches and sequenced samples with Illumina MiSeq. The methods were highly comparable and highly repeatable in three sample types with high microbial biomass (cecum, colon, and feces), but larger differences and low repeatability were found in the microbiomes obtained from the ileum and cloaca. These results will help microbiome researchers assess library preparation procedures and plan their studies accordingly. PMID- 29181450 TI - Cerebrospinal fluid markers to distinguish bacterial meningitis from cerebral malaria in children. AB - Background. Few hospitals in high malaria endemic countries in Africa have the diagnostic capacity for clinically distinguishing acute bacterial meningitis (ABM) from cerebral malaria (CM). As a result, empirical use of antibiotics is necessary. A biochemical marker of ABM would facilitate precise clinical diagnosis and management of these infections and enable rational use of antibiotics. Methods. We used label-free protein quantification by mass spectrometry to identify cerebrospinal fluid (CSF) markers that distinguish ABM (n=37) from CM (n=22) in Kenyan children. Fold change (FC) and false discovery rates (FDR) were used to identify differentially expressed proteins. Subsequently, potential biomarkers were assessed for their ability to discriminate between ABM and CM using receiver operating characteristic (ROC) curves. Results. The host CSF proteome response to ABM ( Haemophilusinfluenza and Streptococcuspneumoniae) is significantly different to CM. Fifty two proteins were differentially expressed (FDR<0.01, Log FC>=2), of which 83% (43/52) were upregulated in ABM compared to CM. Myeloperoxidase and lactotransferrin were present in 37 (100%) and 36 (97%) of ABM cases, respectively, but absent in CM (n=22). Area under the ROC curve (AUC), sensitivity, and specificity were assessed for myeloperoxidase (1, 1, and 1; 95% CI, 1-1) and lactotransferrin (0.98, 0.97, and 1; 95% CI, 0.96-1). Conclusion. Myeloperoxidase and lactotransferrin have a high potential to distinguish ABM from CM and thereby improve clinical management. Their validation requires a larger cohort of samples that includes other bacterial aetiologies of ABM. PMID- 29181449 TI - Transcriptome Sequencing Reveals Novel Candidate Genes for Cardinium hertigii Caused Cytoplasmic Incompatibility and Host-Cell Interaction. AB - Cytoplasmic incompatibility (CI) is an intriguing, widespread, symbiont-induced reproductive failure that decreases offspring production of arthropods through crossing incompatibility of infected males with uninfected females or with females infected with a distinct symbiont genotype. For years, the molecular mechanism of CI remained unknown. Recent genomic, proteomic, biochemical, and cell biological studies have contributed to understanding of CI in the alphaproteobacterium Wolbachia and implicate genes associated with the WO prophage. Besides a recently discovered additional lineage of alphaproteobacterial symbionts only moderately related to Wolbachia, Cardinium (Bacteroidetes) is the only other symbiont known to cause CI, and genomic evidence suggests that it has very little homology with Wolbachia and evolved this phenotype independently. Here, we present the first transcriptomic study of the CI Cardinium strain cEper1, in its natural host, Encarsia suzannae, to detect important CI candidates and genes involved in the insect-Cardinium symbiosis. Highly expressed transcripts included genes involved in manipulating ubiquitination, apoptosis, and host DNA. Female-biased genes encoding ribosomal proteins suggest an increase in general translational activity of Cardinium in female wasps. The results confirm previous genomic analyses that indicated that Wolbachia and Cardinium utilize different genes to induce CI, and transcriptome patterns further highlight expression of some common pathways that these bacteria use to interact with the host and potentially cause this enigmatic and fundamental manipulation of host reproduction. IMPORTANCE The majority of insects carry maternally inherited intracellular bacteria that are important in their hosts' biology, ecology, and evolution. Some of these bacterial symbionts cause a reproductive failure known as cytoplasmic incompatibility (CI). In CI, the mating of symbiont-infected males and uninfected females produces few or no daughters. The CI symbiont then spreads and can have a significant impact on the insect host population. Cardinium, a bacterial endosymbiont of the parasitoid wasp Encarsia in the Bacteroidetes, is the only bacterial lineage known to cause CI outside the Alphaproteobacteria, where Wolbachia and another recently discovered CI symbiont reside. Here, we sought insight into the gene expression of a CI-inducing Cardinium strain in its natural host, Encarsia suzannae. Our study provides the first insights into the Cardinium transcriptome and provides support for the hypothesis that Wolbachia and Cardinium target similar host pathways with distinct and largely unrelated sets of genes. PMID- 29181451 TI - Impact of trichiasis surgery on daily living: A longitudinal study in Ethiopia. AB - Background: Trachomatous trichiasis (TT) may lead to disability, impeding productive activities, resulting in loss of income. This study was conducted to determine if trichiasis surgery improves participation in productive and leisure activities, and ability to perform activities without difficulty or assistance. Methods: We recruited 1000 adults with trichiasis (cases) and 200 comparison participants, matched to every fifth trichiasis case on age (+/- two years), sex and location. The 'Stylised Activity List' tool, developed for the World Bank Living Standard Measurement Survey, was adapted to collect data on activity in the last week (participation in activity, difficulty with activity, requirement of assistance for activity), at baseline and 12 months later. All trichiasis cases received trichiasis surgery at baseline. Random effect logistic regression was used to compare cases and comparison participants. Results: There was strong evidence that trichiasis surgery substantially improves the ability of trichiasis cases to perform all the productive and leisure activities investigated without difficulty, with large increases in processing agricultural products, 21.1% to 87.0% (p<0.0001), farming, 19.1% to 82.4% (p<0.0001), and fetching wood, 25.3% to 86.0% (p<0.0001). Similarly, there was a significant increase in the proportion of cases who could perform activities without assistance, with the largest increases in animal rearing 54.2% to 92.0% (p<0.0001) and farming 73.2% to 96.4% (p<0.0001). There was no change in the proportion of comparison participants performing activities without difficulty or assistance. The change in most of the activities in cases was independent of visual acuity improvement and recurrent TT at 12 months. One year after trichiasis surgery, the proportion of cases reporting ocular pain reduced from 98.9% to 33.7% (p<0.0001). Conclusions: Eyelid surgery for TT improves functional capabilities regardless of vision gains. These data lend strong support to the view that TT surgery improves function and contributes to improved household income and wealth. PMID- 29181452 TI - Prevalences of inherited red blood cell disorders in pregnant women of different ethnicities living along the Thailand-Myanmar border. AB - Background: Inherited red blood cell disorders are prevalent in populations living in malaria endemic areas; G6PD deficiency is associated with oxidant induced haemolysis and abnormal haemoglobin variants may cause chronic anaemia. In pregnant women, microcytic anaemia caused by haemoglobinopathies mimics iron deficiency, complicating diagnosis and treatment. Anaemia during pregnancy is associated with morbidity and mortality. The aim of this study was to characterise the prevalence of G6PD deficiency and haemoglobinopathies among the pregnant population living along the Thailand-Myanmar border. Pregnant women attending antenatal clinics in this area belong to several distinct ethnic groups. Methods: Data were available for 13,520 women attending antenatal care between July 2012 and September 2016. Screening for G6PD deficiency was done by fluorescent spot test routinely. G6PD genotyping and quantitative phenotyping by spectrophotometry were analysed in a subsample of women. Haemoglobin variants were diagnosed by HPLC or capillary electrophoresis and molecular methods. The prevalence and distribution of inherited red blood cell disorders was analysed with respect to ethnicity. Results: G6PD deficiency was common, especially in the Sgaw Karen ethnic group, in whom the G6PD Mahidol variant allele frequency was 20.7%. Quantitative G6PD phenotyping showed that 60.5% of heterozygous women had an intermediate enzymatic activity between 30% and 70% of the population median. HbE, beta-thalassaemia trait and Hb Constant Spring were found overall in 15.6% of women. Only 45.2% of women with low percentage of HbA 2 were carriers of mutations on the alpha globin genes. Conclusions: Distribution of G6PD and haemoglobin variants varied among the different ethnic groups, but the prevalence was generally high throughout the cohort. These findings encourage the implementation of an extended program of information and genetic counselling to women of reproductive age and will help inform future studies and current clinical management of anaemia in the pregnant population in this region. PMID- 29181453 TI - Supporting surveillance capacity for antimicrobial resistance: Laboratory capacity strengthening for drug resistant infections in low and middle income countries. AB - Development of antimicrobial resistance (AMR) threatens our ability to treat common and life threatening infections. Identifying the emergence of AMR requires strengthening of surveillance for AMR, particularly in low and middle-income countries (LMICs) where the burden of infection is highest and health systems are least able to respond. This work aimed, through a combination of desk-based investigation, discussion with colleagues worldwide, and visits to three contrasting countries (Ethiopia, Malawi and Vietnam), to map and compare existing models and surveillance systems for AMR, to examine what worked and what did not work. Current capacity for AMR surveillance varies in LMICs, but and systems in development are focussed on laboratory surveillance. This approach limits understanding of AMR and the extent to which laboratory results can inform local, national and international public health policy. An integrated model, combining clinical, laboratory and demographic surveillance in sentinel sites is more informative and costs for clinical and demographic surveillance are proportionally much lower. The speed and extent to which AMR surveillance can be strengthened depends on the functioning of the health system, and the resources available. Where there is existing laboratory capacity, it may be possible to develop 5-20 sentinel sites with a long term view of establishing comprehensive surveillance; but where health systems are weaker and laboratory infrastructure less developed, available expertise and resources may limit this to 1-2 sentinel sites. Prioritising core functions, such as automated blood cultures, reduces investment at each site. Expertise to support AMR surveillance in LMICs may come from a variety of international, or national, institutions. It is important that these organisations collaborate to support the health systems on which AMR surveillance is built, as well as improving technical capacity specifically relating to AMR surveillance. Strong collaborations, and leadership, drive successful AMR surveillance systems across countries and contexts. PMID- 29181454 TI - Effectiveness of Laboratory Practices to Reducing Patient Misidentification Due to Specimen Labeling Errors at the Time of Specimen Collection in Healthcare Settings: LMBPTM Systematic Review. AB - Background: Specimen labeling errors have long plagued the laboratory industry putting patients at risk of transfusion-related death, medication errors, misdiagnosis, and patient mismanagement. Many interventions have been implemented and deemed to be effective in reducing sample error rates. The objective of this review was to identify and evaluate the effectiveness of laboratory practices/ interventions to develop evidence based recommendations for the best laboratory practices to reduce labeling errors. Content: The standardized LMBPTM A-6 methods were used to conduct this systematic review. Total evidence included 12 studies published during the time periods of 1980 to September 2015. Combined data from seven studies found that the interventions developed as a result of improved communication and collaboration between the laboratory and clinical staff resulted in substantial decrease in specimen labeling errors (Median relative percent change in labeling errors: -75.86; IQI: -84.77, -58.00). Further data from subset of four studies showed a significant decrease in specimen labeling errors after the institution of the standardized specimen labeling protocols (Median relative percent decrease in specimen labeling errors: -72.45; IQI: 83.25, -46.50). Summary: Based on the evidence included in this review, the interventions that enhance the communication and collaboration between laboratory and healthcare professionals can decrease the specimen identification errors in healthcare settings. However, more research is needed to make the conclusion on the effectiveness of other evaluated practices in this review including training and education of the specimen collection staff, audit and feedback of labeling errors, and implementation of new technology (other than barcoding). PMID- 29181455 TI - The New Definition of Oral Health and Relationship between Oral Health and Quality of Life. AB - FDI World Dental Federation, which has 200 dental association members in some 130 countries, is the official representative body and voice of more than 1 million clinicians worldwide. It set itself the task of creating a new definition for oral health as a baseline to develop tools to measure oral health and related indicators. The definition allows FDI to position oral health within the global health agenda in areas such as quality of life and wellbeing and the challenge of an ageing population worldwide. Furthermore, it provides an impetus for FDI activities in favour of worldwide periodontal health. PMID- 29181456 TI - A Review of Excessive Sugar Metabolism on Oral and General Health. AB - Stomatologists and dental practitioners, as they are called in different parts of the world according to tradition and history, are basically physicians who specialise in the study and treatment of diseases of the mouth and surrounding structures. They have always been outstanding in advocating the reduction of sugar consumption, mainly due to its direct connection to the pathogenesis of dental caries. Increasingly, it has come to the attention of researchers, epidemiologists and many healthcare workers and professionals that excessive consumption of sugar is also closely tied to the increase in tandem of our current major health issues like obesity, diabetes, heart, liver and kidney disease, and a host of other associated ailments. This development of current health crises throughout the world wherever traditional diets are replaced with modern fast food diets, which are usually packed with hidden, added refined sugars, is extremely troubling. It becomes all the more urgent and incumbent upon clinicians and stomatologists throughout the world to redouble their efforts to reduce and even eliminate the excessive consumption of added or extrinsic or secondary or hidden sugars to food and drinks. It will not only be to reduce dental caries, but also to reduce the many systemic and organ diseases associated with added sugars and which also exacerbate many oral diseases. This review is to give a basic history of sugar, the current understanding of sugar metabolism and the developing literature and research on the impact of sugar consumption on oral and overall health, as the mouth cannot be divorced from the body and vice versa. The author hopes to kick-start more research into this area that will result in various positive developments in the food and drink industry and persuade stakeholders to comprehensively address this universal health crisis that is closely tied to excessive consumption of added sugar in all its forms. PMID- 29181457 TI - Comparison of Real-Time Quantitative PCR with a Chairside Test for Streptococcus Mutans Assessment. AB - OBJECTIVE: To compare two methods for Streptococcus mutans detection and quantification in the human oral cavity: a chairside commercial test and a molecular-based real-time quantitative polymerase chain reaction (qPCR) method. METHODS: A total of 688 whole saliva samples were collected from 344 children aged 3 and 5 and their biological mothers. Caries status was examined using a World Health Organisation survey method. S. mutans levels were measured using the Dentocult SM Strip mutans test and scored as colony forming units per millilitre of saliva. Meanwhile, bacterial genomic DNA was extracted from the saliva, qPCR was performed with S. mutans species-specific primers, and absolute S. mutans DNA concentrations were obtained and scored as micrograms of DNA per millilitre of saliva. The two methods were compared for sensitivity, specificity, agreement and correlation with caries status. RESULTS: Significantly more participants tested positive for S. mutans by qPCR than in the chairside SM Strip test (82.4% vs 71.4%). When only the highest and lowest test scores were considered, the agreement between the two methods assessing S. mutans colonisation was 0.956. Children with high levels of S. mutans in their saliva were six to eight times more likely to develop dental caries at 5 years old. CONCLUSION: The study provides new evidence supporting the use of the chairside SM Strip test or the qPCR assay for the detection and quantification of S. mutans colonisation in saliva as the analytical approach of choice for caries risk assessment in clinical and epidemiological studies. PMID- 29181458 TI - Minimally Invasive Crestal Sinus Lift Technique and Simultaneous Implant Placement. AB - OBJECTIVE: To evaluate the effectiveness and clinical results of a new crestal sinus lift technique used to elevate the sinus floor simultaneously with bone grafts and implant placement. METHODS: Eleven patients underwent this crestal sinus lift technique performed using an SCA KIT. The mean residual bone height was 6.4 mm (range: 4.1 mm to 8.6 mm). Bio-Oss collagen was used as the graft material, and 12 implants were simultaneously placed after sinus augmentation. Radiographic and clinical examinations were conducted during follow-up. RESULTS: All procedures were successfully performed with no obvious Schneiderian membrane perforation. The sinus floor was augmented with a mean height of 4.8 mm (range: 2.8 to 7.4 mm). Twelve implants healed uneventfully with healing abutments. Peri implant marginal bone was stable, with a mean follow-up of 49.4 months (range: 33 to 71 months). No complications were observed during follow-up. CONCLUSION: According to the limited data collected in this study, the novel crestal sinus lift approach could effectively lift the sinus floor and reduce the incidence of postoperative complications. Additional cases with long-term follow-up are needed to confirm and improve this crestal sinus lift technique. PMID- 29181459 TI - Gallium-67 Scintigraphy in Differential Diagnosis of Malignant Tumours from Non Tumorous Lesions of the Maxilla. AB - OBJECTIVE: To assess the gallium-67 (67Ga) scintigraphy in differential diagnosis of malignant tumours from non-tumorous lesions of the maxilla. METHODS: Nineteen patients with malignant tumours (six cases of squamous cell carcinoma and one case of malignant melanoma) and non-tumorous lesions (seven cases of maxillary sinusitis and five cases of postoperative maxillary changes) in the maxilla underwent 67Ga and bone scintigraphy with CT and MRI. The statistical analysis with respect to comparison between imaging features of 67Ga and bone scintigraphy and maxillary lesions was performed with the Pearson's chi-squared test. RESULTS: 67Ga scintigraphy for six of the seven patients with malignant tumours in the maxilla was positive (85.7%), 0 of 12 patients with non-tumorous lesions were positive (0%) (P = 0.000). Bone scintigraphy for six out of seven patients with malignant tumours was positive (85.7%), 10 of 12 patients with non-tumorous lesions were positive (83.3%) (P = 0.891). CONCLUSION: 67Ga scintigraphy was useful for detection of malignant tumours in the maxilla. However, bone scintigraphy was not an effective technique for interpretation of malignant tumours, maxillary sinusitis and postoperative change in the maxilla. PMID- 29181460 TI - Electrode Placing Sites affect Pulp Vitality Test of Human Incisors and Premolars. AB - OBJECTIVE: To investigate electric pulp test thresholds at different sites on healthy incisors and premolars and determine appropriate test sites. METHODS: Overall, 47 volunteers aged 20 to 30 years were recruited, and 163 incisors and 140 premolars were tested at several sites with an Electric Pulp Tester. One-way analysis of variance and a Tukey test were used to analyse the threshold values among different tooth types and sites. RESULTS: The lowest threshold value for incisors was identified on the incisal edge. The difference of threshold on the incisal edge and other sites was statistically significant in mandibular incisors. For maxillary premolars and the mandibular second premolar, the lowest response was obtained with the tester tip on the lingual slope of the buccal cusp. For the mandibular first premolar, the response at the lingual slope of the buccal cusp, as the second lowest, was slightly higher than that at the buccal cusp. CONCLUSION: The incisal edge for incisors and the lingual slope of the buccal cusp for premolars was favoured as the optimal sites for electric pulp test.

AB - Supernumerary teeth are hyperdontic variants due to abnormalities during tooth development. Here, we report a case on regeneration of bony defect, which ensued following extraction of two supernumerary teeth in the mandibular premolar region, using a combination of bone grafts and platelet-rich fibrin. To the best of our knowledge, it is the first time synergistic use of biomaterials with bone grafts have been used for this type of management. PMID- 29181462 TI - Chemical amplification accelerates reactive oxygen species triggered polymeric degradation. AB - Chemical amplification is a known strategy for improving the sensitivity of stimuli-responsive polymers. However, the chemical amplification effect has never been fully examined. Many questions remain about its mechanism and efficacy, obstructing its further implementation. Here, we design and demonstrate a reactive oxygen species (ROS) responsive polymer (ROS-ARP) with a chemical amplification strategy to dismiss these concerns. The ROS-ARP is designed to change the hydrophilicity by ROS, revealing a carboxylic acid, which also catalyzes ketal hydrolysis along the polymer backbone. The chemical amplification strategy of ROS-ARP accelerated the polymer degradation up to 17 fold compared to a previously reported ROS-responsive polymer. To investigate the mechanism behind this increased acceleration, we compared the degradation kinetics in various environments. Additionally, other effects such as hydrophilicity changes were excluded. The accelerated degradation of ROS-ARP is evaluated as a potential drug delivery system, demonstrating on-demand cargo release from the formulated polymeric particles. PMID- 29181464 TI - Exploration of cell division times during bacterial cytokinesis. AB - Filamenting temperature-sensitive mutant Z (FtsZ), an essential cell division protein in bacteria, has recently emerged as an important and exploitable antibacterial target. The perturbation of FtsZ assembly is found to have an effect on cell cytokinesis and cell survival. Cell division time is an important physical parameter in cell cytokinesis. Here, the theoretical framework that has been developed by combining a phase field model for rod-shaped cells with a kinetic description for FtsZ ring maintenance is extended to explore cell division times during bacterial cytokinesis. The cell division times of around 72 s in the numerical studies have the same magnitude as the division time of several minutes observed physiologically. The dependence of the cell division time on parameters such as the initial state of rod-shaped cells and various kinetic rates of FtsZ assembly dynamics is thoroughly investigated. The theoretical analysis of the relations between the cell division time and these parameters is found to coincide well with the numerical calculated results. PMID- 29181465 TI - Strain engineering of phonon thermal transport properties in monolayer 2H-MoTe2. AB - The effect of strain on the phonon properties such as phonon group velocity, phonon anharmonicity, phonon lifetime, and lattice thermal conductivity of monolayer 2H-MoTe2 is studied by solving the Boltzmann transport equation based on first principles calculations. The phonon thermal transport properties of the unstrained monolayer 2H-MoTe2 are compared to those of the strained case under different biaxial tensile strains. One of the common features of two-dimensional materials is the quadratic nature near the Gamma point of the out-of-plane phonon flexural mode that disappears by applying tensile strain. We find that the lattice thermal conductivity of the monolayer 2H-MoTe2 is very sensitive to strain, and the lattice thermal conductivity is reduced by approximately 2.5 times by applying 8% biaxial tensile strain due to the reduction in phonon group velocities and phonon lifetime. We also analyze how the contribution of each mode to lattice thermal conductivity changes with tensile strain. These results highlight that tensile strain is a key parameter in engineering phonon thermal transport properties in monolayer 2H-MoTe2. PMID- 29181466 TI - Quantum stochastic trajectories: the Smoluchowski-Bohm equation. AB - Molecular systems are quantum systems, but the complete characterization of molecular motions within a fully quantum framework might appear to be an unfeasible task because it would require that the actual nuclear positions are established at any time. One would like to use a quantum molecular trajectory that defines the instantaneous nuclear positions and satisfies the predictions of quantum mechanics in terms of its statistical properties. Even though it can be proven that the single Bohm trajectory provides a representation of the quantum molecular trajectory, this solves the issue only on a theoretical ground: exact solutions of the Schrodinger-Bohm dynamical system are extremely computationally demanding. Therefore, we derive a stochastic equation of Smoluchowski type from the Schrodinger-Bohm dynamics, through projection operator techniques, in order to characterize the molecular motions of open quantum systems. The main quantum features of the motions emerge from the equilibrium distribution, i.e., the wave function's squared modulus integrated on the environment degrees of freedom. Furthermore, we verify the accuracy of the stochastic equation by comparing its predictions with those of the deterministic dynamics for a model system of six interacting harmonic oscillators. The indisputable advantage of this full quantum mechanical approach is that of representing the molecular dynamics, which controls important phenomena like vibrational relaxation, conformational transitions and activated processes, in a self consistent way and at the low computational cost of solving simple stochastic equations. PMID- 29181468 TI - Analysis of dispersive interactions at polymer/TiAlN interfaces by means of dynamic force spectroscopy. AB - The structural and electronic origins of the interactions between polycarbonate and sputter deposited TiAlN were analysed using a combined electron and force spectroscopic approach. Interaction forces were measured by means of dynamic force spectroscopy and the surface polarizability was analysed by X-ray photoelectron valence band spectroscopy. It could be shown that the adhesive interactions between polycarbonate and TiAlN are governed by van der Waals forces. Different surface cleansing and oxidizing treatments were investigated and the effect of the surface chemistry on the force interactions was analysed. Intense surface oxidation resulted in a decreased adhesion force by a factor of two due to the formation of a 2 nm thick Ti0.21Al0.45O surface oxide layer. The origin of the residual adhesion forces caused by the mixed Ti0.21Al0.45O surface oxide was clarified by considering the non-retarded Hamaker coefficients as calculated by Lifshitz theory, based on optical data from Reflection Electron Energy Loss Spectroscopy. This disclosed increased dispersion forces of Ti0.21Al0.45O due to the presence of Ti(iv) ions and related Ti 3d band optical transitions. PMID- 29181469 TI - A full-spectrum photocatalyst with strong near-infrared photoactivity derived from synergy of nano-heterostructured Er3+-doped multi-phase oxides. AB - The development of full-spectrum photocatalysts active in the near-infrared (NIR) region has gained increasing attention in the photodegradation of organic pollutants. Herein, we designed a full-spectrum photocatalyst with strong NIR photoactivity based on the synergy of Er3+-doped ZnO-CuO-ZnAl2O4 multi-phase oxides (Er3+-doped Zn/Cu/Al-MPO) via the formation of n-p-n double heterojunctions. The photocatalyst was prepared by synthesizing nanosheets of a Zn/Cu/Al/Er hydrotalcite-like compound (Zn/Cu/Al/Er-HLC) with a co-precipitation method followed by calcination of the nanosheets at 800 degrees C. The as prepared Er3+-doped Zn/Cu/Al-MPO inherits the nanosheet morphology of Zn/Cu/Al/Er HLC, and displays over-doubled photoactivity in the entire ultraviolet (UV), visible and NIR regions compared to undoped Zn/Cu/Al-MPO. The excellent photocatalytic activity of Er3+-doped Zn/Cu/Al-MPO, especially its strong NIR photoactivity, is ascribed to its Er3+-doped CuO-involved multi-crystalline phase heterostructure, i.e., n-p-n double heterojunctions, which does not only offer an enhanced NIR absorption but also promotes the separation of photogenerated charge carriers. Importantly, the synergy of all the parts of the n-p-n double heterojuctions plays an important role in interface band structure regulation for the enhancement of the photocatalytic properties of Er3+-doped Zn/Cu/Al-MPO. This work has demonstrated the feasibility of utilizing hydrotalcite-like precursors in the design of full-spectrum photocatalysts active in the NIR region. PMID- 29181471 TI - Versatile (eta6-arene)Ni(PCy3) nickel monophosphine precursors. AB - Nickel monophosphine arene adducts have been proposed as highly reactive intermediates capable of difficult C-O bond activation steps in Ni catalyzed cross-coupling reactions. The addition of N-methylmorpholine N-oxide to arene solutions of ([Cy3P)2Ni]2N2 allows for the synthesis of stable (eta6 arene)Ni(PCy3) complexes. The isolation of these species demonstrates their viability as intermediates and provides an experimental means to test the hypothesized importance of the Ni(PCy3) moiety in bond activation and catalysis. PMID- 29181470 TI - Effect of benzocaine and propranolol on phospholipid-based bilayers. AB - Cell membranes play a fundamental role in protecting the cell from its surroundings, in addition to hosting many proteins with fundamental biological tasks. A study of drug/lipid interactions is a necessary and important step in fully clarifying the role and action mechanism of active ingredients, and shedding light on possible complications caused by drug overdosage. In this paper, the influence of benzocaine and propranolol drugs on the structure of l alpha-phosphatidylcholine-based membranes has been investigated by means of neutron reflectivity, grazing incidence small angle neutron scattering, and small/ultra-small angle neutron scattering. Investigations allowed discovering a stiffening of the membranes and the formation of stalks, caused by the presence of benzocaine. On the other hand, disordered bilayers (lamellar powders) and highly curved structures were found in the presence of propranolol. The results obtained may be rationalized in terms of the molecular structures of drugs and may serve as a starting point for explaining the toxic behavior in long-term and overdosage scenarios. PMID- 29181472 TI - Tailoring the dispersion of nanoparticles and the mechanical behavior of polymer nanocomposites by designing the chain architecture. AB - The structure-property relationship of polymer nanocomposites (PNCs) has been extensively investigated, but less effort has been devoted to studying the effect of chain architectures. Herein, through coarse-grained molecular dynamics simulation, we build six different chain architectures namely linear, branch-2 (with two side chains), branch-4 (with four side chains), branch-10 (with ten side chains), star-4 (with four arms) and star-6 (with six arms), by fixing the molecular weight per chain. First, we examine the effect of the interfacial interaction between the polymer and nanoparticles (NPs) epsilonnp on the dispersion of NPs, by calculating the radial distribution function between NPs, the second virial coefficient and the average number of neighbor fillers. We observe a non-monotonic change of the NP dispersion as a function of epsilonnp for all PNCs with different chain architectures, indicating the optimal dispersion of NPs at moderate epsilonnp. Meanwhile, we find that the star-6, branch-4 and linear chains promote the best dispersion of NPs at moderate epsilonnp, compared to the other chain architectures. Then we investigate the strain hardening behavior and chain orientation of these PNCs under uniaxial tension. We find that the star-6 chains demonstrate relatively the most remarkable reinforced mechanical behavior of PNCs. Furthermore, we probe the effect of end-functionalization of polymer chains with different architectures on the dispersion of NPs, by comparing them to the case without any functionalization. We find that the introduction of the end-functionalization benefits mostly the high degree of chain branching for promoting the dispersion of NPs. Meanwhile, we observe that when the tensile strain is small, the branch-4 structure shows relatively improved mechanical properties, however, when the tensile strain is large, the star-6 and branch-10 structures display the best mechanical properties, and the end-functionalization evidently improves the mechanical properties of the PNCs. Our simulation results provide guidelines to tailor the dispersion of NPs and the mechanical properties of PNCs, by taking advantage of the chain architecture and its end-functionalization strategy.

AB - Molecular motion under confinement has important implications for a variety of applications including gas recovery and catalysis. Propane confined in mesoporous silica aerogel as studied using quasielastic neutron scattering (QENS) showed anomalous pressure dependence in its diffusion coefficient (J. Phys. Chem. C, 2015, 119, 18188). Molecular dynamics (MD) simulations are often employed to complement the information obtained from QENS experiments. Here, we report an MD simulation study to probe the anomalous pressure dependence of propane diffusion in silica aerogel. Comparison is attempted based on the self-diffusion coefficients and on the time scales of the decay of the simulated intermediate scattering functions. While the self-diffusion coefficients obtained from the simulated mean squared displacement profiles do not exhibit the anomalous pressure dependence observed in the experiments, the time scales of the decay of the intermediate scattering functions calculated from the simulation data match the corresponding quantities obtained in the QENS experiment and thus confirm the anomalous pressure dependence of the diffusion coefficient. The origin of the anomaly in pressure dependence lies in the presence of an adsorbed layer of propane molecules that seems to dominate the confined propane dynamics at low pressure, thereby lowering the diffusion coefficient. Further, time scales for rotational motion obtained from the simulations explain the absence of rotational contribution to the QENS spectra in the experiments. In particular, the rotational motion of the simulated propane molecules is found to exhibit large angular jumps at lower pressure. The present MD simulation work thus reveals important new insights into the origin of anomalous pressure dependence of propane diffusivity in silica mesopores and supplements the information obtained experimentally by QENS data.

AB - Two types of monolithic stationary phases with incorporated hydroxyl functionalized multiwalled carbon nanotubes (OH-MWCNTs) were introduced and evaluated, namely, the poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) monolith, denoted as poly(GMA-co-EDMA), and a diol derivative of the poly(GMA-co-EDMA) monolith. The diol derivative monolith was obtained by subjecting the poly(GMA-co-EDMA) monolith with physically incorporated OH-MWCNTs to an acid treatment with 0.1 M sulfuric acid at a moderate temperature of 50 degrees C for a total of 7.5 h. Also, the poly(GMA-co-EDMA) monolith with both physically and covalently incorporated OH-MWCNTs was prepared by subjecting the physically incorporated monolithic column to a Lewis acid catalyzed reaction in the presence of BF3 in order to react some of the OH-MWCNTs with the epoxy rings of the poly(GMA-co-EDMA) monolith. In all cases, the OH-MWCNTs were subjected to high power sonication at an output power of 10 W for 15 min with the aim of better dispersing the incorporated nanotubes into the monoliths under investigation. In fact, high power sonication yielded columns with a relatively higher plate count (~2 fold increase) when compared to low power sonication. While the incorporation of OH-MWCNTs into the poly(GMA-co-EDMA) monolith acted as an amendment boosting the nonpolar character of the monolith and providing additional pi-pi interactions, the diol derivative monolith with its polar backbone character acted nearly as a support for the OH-MWCNT stationary phase giving rise to a carbon nanotube sorbent providing hydrophobic and pi-pi interactions via the incorporated OH-MWCNTs. These two kinds of columns were evaluated using alkylbenzenes, toluene derivatives, aniline compounds, phenols and polyaromatic hydrocarbons. PMID- 29181475 TI - Synthesis and chemical transformation of Ni nanoparticles embedded in silica. AB - Ni nanoparticles (NPs) catalyze many chemical reactions, in which they can become contaminated or agglomerate, resulting in poorer performance. We report deposition of silica (SiO2) onto Ni NPs from tetraethyl orthysilicate (TEOS) through a reverse microemulsion approach, which is accompanied by an unexpected etching process. Ni NPs with an average initial diameter of 27 nm were embedded in composite SiO2-overcoated Ni NPs (SiO2-Ni NPs) with an average diameter of 30 nm. Each SiO2-Ni NP contained a ~7 nm oxidized Ni core and numerous smaller oxidized Ni NPs with diameters of ~2 nm distributed throughout the SiO2 shell. Etching of the Ni NPs is attributed to use of ammonium hydroxide as a catalyst for deposition of SiO2. Aliquots acquired during the deposition and etching process reveal agglomeration of SiO2 and Ni NPs, followed by dissociation into highly uniform SiO2-Ni NPs. This etching and embedding process may also be extended to other core materials. The stability of SiO2-Ni NPs was also investigated under high-temperature oxidizing and reducing environments. The structure of the SiO2-Ni NPs remained significantly unchanged after both oxidation and reduction, which suggests structural durability when used for catalysis.

This non-noble metal-catalyzed protocol enables facile and efficient access to valuable alpha-keto imides in generally good to excellent yields. Other notable features of this method include widespread availability of the substrates, compatibility with broad functional groups, a simple procedure, mild conditions, and in particular, no need to exclude moisture or air ("open flask"). PMID- 29181479 TI - Ruthenium complex-modified carbon nanodots for lysosome-targeted one- and two photon imaging and photodynamic therapy. AB - Nanohybrids can in most cases kill cancer cells more efficiently as compared with free photosensitizers. In this work, we constructed nanohybrid Ru1@CDs composed of carbon nanodots (CDs) and a phosphorescent Ru(ii) complex (Ru1) for one- and two-photon photodynamic therapy of cancer. The photosensitizer and imaging agent Ru1 is decorated onto the nanocarrier CDs covalently. Ru1 and Ru1@CDs can penetrate into cancer cells through an energy-dependent mechanism and endocytosis, respectively. Both Ru1 and Ru1@CDs are capable of lysosome-targeted phosphorescence imaging and photodamage under either 450 nm (one-photon) or 810 nm (two-photon) excitation. Conjugation with CDs can increase the cellular uptake efficacy of Ru1. Mechanism investigations show that both Ru1 and Ru1@CDs can induce apoptosis through generation of reactive oxygen species and cathepsin initiated apoptotic signaling pathways. Upon two-photon excitation, Ru1@CDs show better penetrability, as well as higher inhibitory effects on cancer cell growth in both 2D cell and 3D multicellular tumor spheroid models. Our work provides an effective strategy for the construction of multifunctional imaging and phototherapeutic nanohybrids for the treatment of cancer. PMID- 29181480 TI - Clarifying the dehydrogenation pathway of catalysed Li4(NH2)3BH4-LiH composites. AB - The effect of different metal oxides (Co3O4 and NiO) on the dehydrogenation reaction pathways of the Li4(NH2)3BH4-LiH composite was investigated. The additives were reduced to metallic species i.e. Co and Ni which act as catalysts by breaking the B-H bonds in the Li-B-N-H compounds. The onset decomposition temperature was lowered by 32 degrees C for the Ni-catalysed sample, which released 8.8 wt% hydrogen below 275 degrees C. It was demonstrated that the decomposition of the doped composite followed a mechanism via LiNH2 and Li3BN2 formation as the end product with a strong reduction of NH3 emission. The sample could be partially re-hydrogenated (~1.5 wt%) due to lithium imide/amide transformation. To understand the role of LiH, Li4(NH2)3BH4-LiH-NiO and Li4(NH2)3BH4-NiO composites were compared. The absence of LiH as a reactant forced the system to follow another path, which involved the formation of an intermediate phase of composition Li3BN2H2 at the early stages of dehydrogenation and the end products LiNH2 and monoclinic Li3BN2. We provided evidence for the interaction between NiO and LiNH2 during heating and proposed that the presence of Li facilitates a NHx-rich environment and the Ni catalyst mediates the electron transfer to promote NHx coupling. PMID- 29181481 TI - A graphene-like membrane with an ultrahigh water flux for desalination. AB - An ultrathin nanoporous membrane which combines high water permeability and high salt rejection is the core of ultrafiltration technology. Recently, we reported the synthesis of a chemically robust and nanoporous two-dimensional conjugated aromatic polymer (2D-CAP) membrane. Due to its array of highly regular sub nanometer pores and channels, the ultrathin 2D-CAP membrane can be potentially used in desalination. Herein, we used molecular dynamics simulations to analyze the transmembrane hydrodynamics of mono- and multi-layer 2D-CAP membranes as a function of layer number. The energy barriers to water and ions across these membranes were calculated to evaluate the potential of 2D-CAP to function as the ultimate RO membrane. Our simulation results show that the bilayer CAP membrane exhibits superior ion rejection (100%) and a water flux (1172 L m-2 h-1 bar-1) with a performance that is three orders of magnitude higher than the commercial reverse osmosis membrane, which is three times higher than the theoretically reported monolayer nanoporous MoS2 membrane (the state-of-the-art membrane reported for desalination). In addition, the 2D-CAP bilayer membrane is highly resistant to swelling even at a high water flux. The monolayer 2D-CAP membrane shows good ion selectivity between monovalent and divalent ions.

AB - Polyphenols such as Epigallocatechin-3 gallate (EGCG) are currently bearer of hope to prevent or at least to slow down the deleterious effect of Tauopathies such as Alzheimer disease. One of the main effects of these neurodegenerative pathologies is the hyperphosphorylation and consequent aggregation of the Tau protein that leads to the irremediable neuronal cells death. In the present paper, we show how EGCG can play a crucial role to prevent Tau aggregation: (i) in binding Tau in its phosphorylation region with an affinity of the same order of magnitude than kinases (0.5 mM), hindering their access to the protein and (ii) in modifying the 3D-structure of Tau whose preferential conformation changes in the presence of EGCG. For this purpose, two peptides were synthesized, one of 20 residues long issued from the first Proline-rich region of Tau (171Ile 190Lys), the second of 50 residues long (171Ile-220Thr) corresponding to more than 50% of the Tau Proline rich domaine. The total attribution of all the 1H, 13C and 15N resonances of the two peptides has been achieved thanks to a "divide and conquer" strategy leading to their 3D structure preference and their affinity towards EGCG. PMID- 29181488 TI - Preclinical and Clinical Development of ABBV-8E12, a Humanized Anti-Tau Antibody, for Treatment of Alzheimer's Disease and Other Tauopathies. AB - Tau neurofibrillary tangles are found in the brains of patients suffering from Alzheimer's disease and other tauopathies. The progressive spreading of tau pathology from one brain region to the next is believed to be caused by extracellular transsynaptic transmission of misfolded tau between neurons. Preclinical studies have shown that antibodies against tau can prevent this transfer of misfolded tau between cells. Thus, antibodies against tau have the potential to stop or slow the progression of tau pathology observed in human tauopathies. To test this hypothesis, a humanized anti-tau antibody (ABBV-8E12) was developed and a phase 1 clinical trial of this antibody has been completed. The double-blind, placebo-controlled phase 1 study tested single doses of ABBV 8E12 ranging from 2.5 to 50 mg/kg in 30 patients with progressive supranuclear palsy (PSP). ABBV-8E12 was found to have an acceptable safety profile with no clinically concerning trends in the number or severity of adverse events between the placebo and dosed groups. Pharmacokinetic modelling showed that the antibody has a plasma half-life and cerebrospinal fluid:plasma ratio consistent with other humanized antibodies, and there were no signs of immunogenicity against ABBV 8E12. Based on the acceptable safety and tolerability profile of single doses of ABBV-8E12, AbbVie is currently enrolling patients into two phase 2 clinical trials to assess efficacy and safety of multiple doses of ABBV-8E12 in patients with early Alzheimer's disease or PSP. PMID- 29181487 TI - Vitamin E Supplementation Reduces Cellular Loss in the Brain of a Premature Aging Mouse Model. AB - BACKGROUND: Aging is a highly complex biological process driven by multiple factors. Its progression can partially be influenced by nutritional interventions. Vitamin E is a lipid-soluble anti-oxidant that is investigated as nutritional supplement for its ability to prevent or delay the onset of specific aging pathologies, including neurodegenerative disorders. PURPOSE: We aimed here to investigate the effect of vitamin E during aging progression in a well characterized mouse model for premature aging. METHOD: Xpg-/- animals received diets with low (~2.5 mg/kg feed), medium (75 mg/kg feed) or high (375 mg/kg feed) vitamin E concentration and their phenotype was monitored during aging progression. Vitamin E content was analyzed in the feed, for stability reasons, and in mouse plasma, brain, and liver, for effectiveness of the treatment. Subsequent age-related changes were monitored for improvement by increased vitamin E or worsening by depletion in both liver and nervous system, organs sensitive to oxidative stress. RESULTS: Mice supplemented with high levels of vitamin E showed a delayed onset of age-related body weight decline and appearance of tremors when compared to mice with a low dietary vitamin E intake. DNA damage resulting in liver abnormalities such as changes in polyploidy, was considerably prevented by elevated amounts of vitamin E. Additionally, immunohistochemical analyses revealed that high intake of vitamin E, when compared with low and medium levels of vitamin E in the diet, reduces the number of p53-positive cells throughout the brain, indicative of a lower number of cells dying due to DNA damage accumulated over time. CONCLUSIONS: Our data underline a neuroprotective role of vitamin E in the premature aging animal model used in this study, likely via a reduction of oxidative stress, and implies the importance of improved nutrition to sustain health. PMID- 29181489 TI - The Alzheimer's Prevention Initiative Generation Program: Evaluating CNP520 Efficacy in the Prevention of Alzheimer's Disease. AB - Alzheimer's disease pathology begins decades before the onset of clinical symptoms. This provides an opportunity for interventional clinical trials to potentially delay or prevent the onset of cognitive impairment or dementia. CNP520 (a beta-site-amyloid precursor protein-cleaving enzyme inhibitor) is in clinical development for the treatment of preclinical Alzheimer's disease under the Alzheimer's Prevention Initiative Generation Program. The Alzheimer's Prevention Initiative is a public-private partnership intended to accelerate the evaluation of Alzheimer's disease prevention therapies. The Generation Program comprises two pivotal phase II/III studies with similar designs to assess the efficacy and safety of investigational treatments in a cognitively unimpaired population at increased risk for developing Alzheimer's disease based on age and apolipoprotein E (APOE) genotype (i.e., presence of the APOE epsilon4 allele). The program has been designed to maximize benefit to Alzheimer's disease research. Generation Study 1 (NCT02565511) and Generation Study 2 (NCT03131453) are currently enrolling; their key features are presented here. PMID- 29181490 TI - Development Review of the BACE1 Inhibitor Lanabecestat (AZD3293/LY3314814). AB - Several ongoing clinical development programs are investigating potential disease modifying treatments for Alzheimer's disease (AD), including lanabecestat (AZD3293/LY3314814). Lanabecestat is a brain-permeable oral inhibitor of human beta-site amyloid (Abeta) precursor protein-cleaving enzyme 1 (BACE1) that reduces Abeta production. As a potent BACE1 inhibitor, lanabecestat significantly reduced soluble Abeta species and soluble amyloid precursor proteins (sAPPbeta) in mouse, guinea pig, and dog in a time- and dose-dependent manner. Significant reductions in plasma and cerebrospinal fluid (CSF) Abeta1-40 and Abeta1-42 were observed in Phase 1 studies of healthy subjects and AD patients treated with lanabecestat. Three lanabecestat trials are ongoing and intended to support registration in Early AD: (1) Phase 2/3 study in patients with mild cognitive impairment (MCI) due to AD and mild AD dementia (AMARANTH, NCT02245737); (2) Delayed-start extension study (AMARANTH-EXTENSION, NCT02972658) for patients who have completed treatment in the AMARANTH Study; and (3) Phase 3 study in mild AD dementia (DAYBREAK-ALZ, NCT02783573). This review will discuss the development of lanabecestat, results from the completed nonclinical and clinical studies, as well as describe the ongoing Phase 3 clinical trials. PMID- 29181491 TI - Clinical Development of Aducanumab, an Anti-Abeta Human Monoclonal Antibody Being Investigated for the Treatment of Early Alzheimer's Disease. AB - The amyloid hypothesis has been the dominant framework for Alzheimer's disease (AD) research, including the development of anti-AD therapies. However, none of the phase III clinical trials conducted to date that targeted amyloid beta (Abeta) production, aggregation, or clearance demonstrated a statistically significant treatment effect in patients with AD. This includes the approach of using monoclonal antibodies that recognize various Abeta epitopes and display different binding selectivity. While some monoclonal antibodies have failed in phase III trials, several are still in development. Aducanumab (BIIB037) is a human antibody that selectively targets aggregated forms of Abeta, including soluble oligomers and insoluble fibrils. In PRIME (NCT01677572), an ongoing phase Ib trial (N=196 patients dosed), aducanumab was shown to reduce Abeta plaques and slow decline in clinical measures in patients with prodromal or mild AD, with acceptable safety and tolerability. The main safety finding was amyloid-related imaging abnormalities (ARIA), a side effect associated with removal of Abeta, which was dose-dependent and occurred more often in ApoE epsilon4 carriers than non-carriers. ENGAGE (NCT02477800) and EMERGE (NCT02484547), the ongoing phase III trials of aducanumab in early AD, have been designed based on the outcomes of PRIME and on lessons from past clinical trials in patients with AD. Those study design features include patient selection with confirmed Abeta pathology, ensuring sufficient target engagement, and conducting clinical trials in patients at earlier symptomatic stages of AD. PMID- 29181492 TI - Developing Disease-Modifying Treatments in Alzheimer's Disease - A Perspective from Roche and Genentech. AB - Alzheimer's disease (AD) is a chronic neurodegenerative disease for which no preventative or disease-modifying treatments currently exist. Pathological hallmarks include amyloid plaques and neurofibrillary tangles composed of hyper phosphorylated tau protein. Evidence suggests that both pathologies are self propagating once established. However, the lag time between neuropathological changes in the brain and the onset of even subtle clinical symptomatology means that patients are often diagnosed late when pathology, and neurodegeneration secondary to these changes, may have been established for several years. Complex pathological pathways associated with susceptibility to AD and changes that occur downstream of the neuropathologic process further contribute to the challenging endeavour of developing novel disease-modifying therapy. Recognising this complexity, effective management of AD must include reliable screening and early diagnosis in combination with effective therapeutic management of the pathological processes. Roche and Genentech are committed to addressing these unmet needs through developing a comprehensive portfolio of diagnostics and novel therapies. Beginning with the most scientifically supported targets, this approach includes two targeted amyloid-beta monoclonal antibody therapies, crenezumab and gantenerumab, and an anti-tau monoclonal antibody, RO7105705, as well as a robust biomarker platform to aid in the early identification of people at risk or in the early stages of AD. Identification and implementation of diagnostic tools will support the enrolment of patients into clinical trials; furthermore, these tools should also support evaluation of the clinical efficacy and safety profile of the novel therapeutic agents tested in these trials. This review discusses the therapeutic agents currently under clinical development. PMID- 29181493 TI - Neflamapimod: Clinical Phase 2b-Ready Oral Small Molecule Inhibitor of p38alpha to Reverse Synaptic Dysfunction in Early Alzheimer's Disease. AB - Neflamapimod (previously code named VX-745) is a clinical phase 2b-ready highly specific inhibitor of the intra-cellular enzyme p38 mitogen activated protein kinase alpha ("p38alpha") that is being developed as a disease-modifying drug for Alzheimer's disease (AD) that acts via targeting synaptic dysfunction. Neflamapimod was discovered through a proprietary structure-based drug discovery platform at Vertex Pharmaceuticals, and developed previously by Vertex through to phase 2a in rheumatoid arthritis. EIP Pharma licensed the compound in 2014 for development and commercialization as a treatment of central nervous system (CNS) disorders. Neflamapimod is the most advanced in the clinic drug that targets specific molecular mechanisms within neurons that leads to synaptic dysfunction, the pathogenic process that is now considered to be a major driver of the development of memory deficits and disease progression in the early stages of AD. Based on the scientific rationale of targeting synaptic dysfunction and the preclinical data, neflamapimod has the potential to both reverse memory deficits and slow disease progression. Phase 2a clinical data in patients with early-stage AD (MMSE 20-28, biomarker positive) provides evidence that the preclinical science may be translatable to human Alzheimer's, as 6- to 12-weeks of neflamapimod treatment led to significant improvement in episodic memory, the best clinical measure of synaptic dysfunction in AD. A phase 2b six-month placebo controlled 150-patient clinical study is anticipated to start by end of 2017. This study is designed to definitively demonstrate that neflamapimod reverses memory deficits, and also to provide preliminary evidence that the drug slows disease progression.

AB - Importance: Most neonates admitted to a neonatal intensive care unit (NICU) are born at gestational age (GA) of 34 weeks or more. The degree of uniformity of admission criteria for these infants is unclear, particularly at the low-acuity end of the range of conditions warranting admission. Objectives: To describe variation in NICU admission rates for neonates born at GA of 34 weeks or more and examine whether such variation is associated with high illness acuity or designated facility level of care. Design, Setting, and Participants: Cross sectional study of 35 921 NICU inborn admissions of GA at 34 weeks or more during calendar year 2015, using a population database of inborn NICU admissions at 130 of the 149 hospitals in California with a NICU. The aggregate service population comprised 358 453 live births. The individual NICU was the unit of observation and analysis. The analysis was stratified by designated facility level of care and correlations with the percentage admissions with high illness acuity were explored. The hypothesis at the outset of the study was that inborn admission rates would correlate positively with the percentage of admissions with high illness acuity. Exposures: Live birth at GA of 34 weeks or more. Main Outcomes and Measures: Inborn NICU admission rate. Results: Of the total of 358 453 live births at GA of 34 weeks or more, 35 921 infants were admitted to a NICU and accounted for 79.2% of all inborn NICU admissions; 4260 (11.9%) of these admissions met high illness acuity criteria. Inborn admission rates varied 34 fold, from 1.1% to 37.7% of births (median, 9.7%; mean [SD], 10.6% [5.8%]). Percentage with high illness acuity varied 40-fold, from 2.4% to 95% (median, 11.3%; mean, 13.2% [9.9%]). Inborn admission rate correlated inversely with percentage of admissions with high illness acuity (Spearman rho = -0.3034, P < .001). Among regional NICUs capable of caring for patients with the highest degree of illness and support needs, inborn admission rate did not significantly correlate with percentage of admissions with high illness acuity (Spearman rho = 0.21, P = .41). Conclusions and Relevance: Percentage of admissions with high illness acuity does not explain 34-fold variation in NICU inborn admission rates for neonates born at GA of 34 weeks or more. The findings are consistent with a supply-sensitive care component and invite future investigation to clarify the lower-acuity end of the range of conditions considered to warrant neonatal intensive care. PMID- 29181500 TI - Perinatal Diagnosis, Management, and Follow-up of Cystic Renal Diseases: A Clinical Practice Recommendation With Systematic Literature Reviews. AB - Importance: Prenatal and neonatal cystic kidney diseases are a group of rare disorders manifesting as single, multiple unilateral, or bilateral cysts or with increased echogenicity of the renal cortex without macroscopic cysts. They may be accompanied by grossly enlarged kidneys, renal oligohydramnios, pulmonary hypoplasia, extrarenal abnormalities, and neonatal kidney failure. The prognosis is extremely variable from trivial to very severe or even uniformly fatal, which poses significant challenges to prenatal counseling and management. Objective: To provide a clinical practice recommendation for fetal medicine specialists, obstetricians, neonatologists, pediatric nephrologists, pediatricians, and human geneticists by aggregating current evidence and consensus expert opinion on current management of cystic nephropathies before and after birth. Methods: After 8 systematic literature reviews on clinically relevant questions were prepared (including 90 studies up to mid-2016), recommendations were formulated and formally graded at a consensus meeting that included experts from all relevant specialties. After further discussion, the final version was voted on by all members using the Delphi method. The recommendations were reviewed and endorsed by the working groups on inherited renal disorders of the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) and European Society for Paediatric Nephrology (ESPN); the German Society of Obstetrics and Gynecology (DGGG), German Society of Perinatal Medicine (DGPM), and German Society of Ultrasound in Medicine (DEGUM); and the alliance of patient organizations, PKD International. Recommendations: The group makes a number of recommendations on prenatal and postnatal imaging by ultrasound and magnetic resonance imaging, genetic testing, prenatal counseling, in utero therapeutic interventions, and postnatal management of prenatal and neonatal cystic kidney diseases, including provision of renal replacement therapy in neonates. In addition to detailed knowledge about possible etiologies and their prognosis, physicians need to be aware of recent improvements and remaining challenges of childhood chronic kidney disease, neonatal renal replacement therapy, and intensive pulmonary care to manage these cases and to empower parents for informed decision making.

PMID- 29181503 TI - Anticipatory smooth pursuit eye movements evoked by probabilistic cues. AB - Anticipatory smooth eye movements (ASEM; smooth eye movements in the direction of anticipated target motion) are elicited by cues that signal the direction of future target motion with high levels of certainty. Natural cues, however, rarely convey information with perfect certainty, and responses to uncertainty provide insights about how predictive behaviors are generated. Subjects smoothly pursued targets that moved to the right or left with varying cued probabilities. ASEM strength in a given direction increased with the probability level. The type of cue also played a role. ASEM elicited by symbolic visual cues tended to underweight low probabilities and overweight high probabilities. Cues based on memory (varying the proportion of trials with left or right motion) produced the opposite pattern, overweighting low probabilities and underweighting high probabilities. Finally, cues whose perceptual structure depicted the motion path produced a bias in ASEM in the depicted direction that was maintained across levels of cue congruency. The results show that the smooth pursuit system relies on a combination of signals, including memory for recent target motions, interpretation of cues, and prior beliefs about the relationship between the perceptual configuration and the motion path to determine the anticipatory response in the presence of uncertainty. PMID- 29181504 TI - Patient-Sharing Networks of Physicians and Health Care Utilization and Spending Among Medicare Beneficiaries. AB - Importance: Physicians are embedded in informal networks in which they share patients, information, and behaviors. Objective: We examined the association between physician network properties and health care spending, utilization, and quality of care among Medicare beneficiaries. Design, Setting, and Participants: In this cross-sectional study, we applied methods from social network analysis to Medicare administrative data from 2006 to 2010 for an average of 3 761 223 Medicare beneficiaries per year seen by 40 241 physicians practicing in 51 hospital referral regions (HRRs) to identify networks of physicians linked by shared patients. We improved on prior methods by restricting links to physicians who shared patients for distinct episodes of care, thereby excluding potentially spurious linkages between physicians treating common patients but for unrelated reasons. We also identified naturally occurring communities of more tightly linked physicians in each region. We examined the relationship between network properties measured in the prior year and outcomes in the subsequent year using regression models. Main Outcomes and Measures: Spending on total medical services, hospital, physician, and other services, use of services, and quality of care. Results: The mean patient age across the 5 years of study was 72.3 years and 58.5% of the participants were women. The mean age across communities of included physicians was 49 years and approximately 78% were men. Mean total annual spending per patient was $10 051. Total spending was higher for patients of physicians with more connections to other physicians ($1009 for a 1-standard deviation increase, P < .001) and more shared care outside of their community ($172, P < .001). Spending on inpatient care was slightly lower for patients of physicians whose communities had higher proportions of primary care physicians ( $38, P < .001). Patients cared for by physicians linked to more physicians also had more hospital admissions and days (0.02 and 0.18, respectively; both P < .001 for a 1-standard deviation increase in the number of connected physicians), more emergency visits (0.02, P < .001), more visits to specialists (0.37, P < .001), and more primary care visits (0.11, P < .001). Patients whose physicians' networks had more primary care physicians had more primary care visits (0.44, P < .001) and fewer specialist and emergency visits (-0.33 [P < .001] and -0.008 [P = .008], respectively). The various measures of quality were inconsistently related to the network measures.

PMID- 29181509 TI - Effect of Several Negative Rounds of Human Papillomavirus and Cytology Co-testing on Safety Against Cervical Cancer: An Observational Cohort Study. AB - Background: Current U.S. cervical cancer screening and management guidelines do not consider previous screening history, because data on multiple-round human papillomavirus (HPV) and cytology "co-testing" have been unavailable. Objective: To measure cervical cancer risk in routine practice after successive negative screening co-tests at 3-year intervals. Design: Observational cohort study. Setting: Integrated health care system (Kaiser Permanente Northern California, Oakland, California). Patients: 990 013 women who had 1 or more co-tests from 2003 to 2014. Measurements: 3- and 5-year cumulative detection of (risk for) cervical intraepithelial neoplasia grade 3, adenocarcinoma in situ, and cervical cancer (>=CIN3) in women with different numbers of negative co-tests, overall and within subgroups defined by previous co-test results or baseline age. Results: Five-year >=CIN3 risks decreased after each successive negative co-test screening round (0.098%, 0.052%, and 0.035%). Five-year >=CIN3 risks for an HPV-negative co test, regardless of the cytology result, nearly matched the performance (reassurance) of a negative co-test for each successive round of screening (0.114%, 0.061%, and 0.041%). By comparison, >=CIN3 risks for the cytology negative co-test, regardless of the HPV result, also decreased with each successive round, but 3-year risks were as high as 5-year risks after an HPV negative co-test (0.199%, 0.065%, and 0.043%). No interval cervical cancer cases were diagnosed after the second negative co-test. Independently, >=CIN3 risks decreased with age. Length of previous screening interval did not influence future >=CIN3 risks. Limitation: Interval-censored observational data. Conclusion: After 1 or more negative cervical co-tests (or HPV tests), longer screening intervals (every 5 years or more) might be feasible and safe.

AB - Background: When risk adjustment is inadequate and incentives are weak, pay-for performance programs, such as the Value-Based Payment Modifier (Value Modifier [VM]) implemented by the Centers for Medicare & Medicaid Services, may contribute to health care disparities without improving performance on average. Objective: To estimate the association between VM exposure and performance on quality and spending measures and to assess the effects of adjusting for additional patient characteristics on performance differences between practices serving higher-risk and those serving lower-risk patients. Design: Exploiting the phase-in of the VM on the basis of practice size, regression discontinuity analysis and 2014 Medicare claims were used to estimate differences in practice performance associated with exposure of practices with 100 or more clinicians to full VM incentives (bonuses and penalties) and exposure of practices with 10 or more clinicians to partial incentives (bonuses only). Analyses were repeated with 2015 claims to estimate performance differences associated with a second year of exposure above the threshold of 100 or more clinicians. Performance differences were assessed between practices serving higher- and those serving lower-risk patients after standard Medicare adjustments versus adjustment for additional patient characteristics. Setting: Fee-for-service Medicare. Patients: Random 20% sample of beneficiaries. Measurements: Hospitalization for ambulatory care sensitive conditions, all-cause 30-day readmissions, Medicare spending, and mortality. Results: No statistically significant discontinuities were found at the threshold of 10 or more or 100 or more clinicians in the relationship between practice size and performance on quality or spending measures in either year. Adjustment for additional patient characteristics narrowed performance differences by 9.2% to 67.9% between practices in the highest and those in the lowest quartile of Medicaid patients and Hierarchical Condition Category scores. Limitation: Observational design and administrative data. Conclusion: The VM was not associated with differences in performance on program measures. Performance differences between practices serving higher- and those serving lower-risk patients were affected considerably by additional adjustments, suggesting a potential for Medicare's pay-for-performance programs to exacerbate health care disparities.

PMID- 29181510 TI - Neurologic Phenotypes Associated With Mutations in RTN4IP1 (OPA10) in Children and Young Adults. AB - Importance: Neurologic disorders with isolated symptoms or complex syndromes are relatively frequent among mitochondrial inherited diseases. Recessive RTN4IP1 gene mutations have been shown to cause isolated and syndromic optic neuropathies. Objective: To define the spectrum of clinical phenotypes associated with mutations in RTN4IP1 encoding a mitochondrial quinone oxidoreductase. Design, Setting, and Participants: This study involved 12 individuals from 11 families with severe central nervous system diseases and optic atrophy. Targeted and whole-exome sequencing were performed-at Hospital Angers (France), Institute of Neurology Milan (Italy), Imagine Institute Paris (France), Helmoltz Zentrum of Munich (Germany), and Beijing Genomics Institute (China)-to clarify the molecular diagnosis of patients. Each patient's neurologic, ophthalmologic, magnetic resonance imaging, and biochemical features were investigated. This study was conducted from May 1, 2014, to June 30, 2016. Main Outcomes and Measures: Recessive mutations in RTN4IP1 were identified. Clinical presentations ranged from isolated optic atrophy to severe encephalopathies. Results: Of the 12 individuals in the study, 6 (50%) were male and 6 (50%) were female. They ranged in age from 5 months to 32 years. Of the 11 families, 6 (5 of whom were consanguineous) had a member or members who presented isolated optic atrophy with the already reported p.Arg103His or the novel p.Ile362Phe, p.Met43Ile, and p.Tyr51Cys amino acid changes. The 5 other families had a member or members who presented severe neurologic syndromes with a common core of symptoms, including optic atrophy, seizure, intellectual disability, growth retardation, and elevated lactate levels. Additional clinical features of those affected were deafness, abnormalities on magnetic resonance images of the brain, stridor, and abnormal electroencephalographic patterns, all of which eventually led to death before age 3 years. In these patients, novel and very rare homozygous and compound heterozygous mutations were identified that led to the absence of the protein and complex I disassembly as well as mild mitochondrial network fragmentation. Conclusions and Relevance: A broad clinical spectrum of neurologic features, ranging from isolated optic atrophy to severe early-onset encephalopathies, is associated with RTN4IP1 biallelic mutations and should prompt RTN4IP1 screening in both syndromic neurologic presentations and nonsyndromic recessive optic neuropathies.

PMID- 29181514 TI - Comparative Analysis of Biopsy Upgrading in Four Prostate Cancer Active Surveillance Cohorts. AB - Background: Active surveillance (AS) is increasingly accepted for managing low risk prostate cancer, yet there is no consensus about implementation. This lack of consensus is due in part to uncertainty about risks for disease progression, which have not been systematically compared or integrated across AS studies with variable surveillance protocols and dropout to active treatment. Objective: To compare risks for upgrading from a Gleason score (GS) of 6 or less to 7 or more across AS studies after accounting for differences in surveillance intervals and competing treatments and to evaluate tradeoffs of more versus less frequent biopsies. Design: Joint statistical model of longitudinal prostate-specific antigen (PSA) levels and risks for biopsy upgrading. Setting: Johns Hopkins University (JHU); Canary Prostate Active Surveillance Study (PASS); University of California, San Francisco (UCSF); and University of Toronto (UT) AS studies. Patients: 2576 men aged 40 to 80 years with a GS between 2 and 6 and clinical stage T1 or T2 prostate cancer enrolled between 1995 and 2014. Measurements: PSA levels and biopsy GSs. Results: After variable surveillance intervals and competing treatments were accounted for, estimated risks for biopsy upgrading were similar in the PASS and UT studies but higher in UCSF and lower in JHU studies. All cohorts had a delay of 3 to 5 months in detecting upgrading with biennial biopsies starting after a first confirmatory biopsy versus annual biopsies. Limitation: The model does not account for possible misclassification of biopsy GS. Conclusion: Men in different AS studies have different risks for biopsy upgrading after variable surveillance protocols and competing treatments are accounted for. Despite these differences, the consequences of more versus less frequent biopsies seem to be similar across cohorts. Biennial biopsies seem to be an acceptable alternative to annual biopsies.

AB - Context: Both adherence and outcomes are more difficult to measure in patients with multiple sclerosis (MS) than in patients with diseases such as hypertension, for which most medications are taken orally and surrogate outcomes (eg, blood pressure) are routinely collected. Objectives: To characterize the adherence and outcomes of patients with MS within a large integrated health system and to assess the relationship between adherence and outcomes. Study Design: Retrospective review of adherence and health care utilization outcomes via electronic health records and claims (2004-2013) combined with a prospective survey regarding adherence and functional outcomes (2012-2013). Methods: Retrospectively, medication possession ratios were calculated, and adherence groups were compared regarding health care utilization and costs. Prospectively, patients were recruited to complete questionnaires to measure self-reported adherence (SRA) and MS-specific outcomes, including the Multiple Sclerosis Impact Scale (MSIS), the Kurtzke Expanded Disability Status Scale (EDSS), and the Treatment Satisfaction Questionnaire for Medication (TSQM). Regression was used to statistically test for differences in these outcomes among adherence groups. Results: A total of 681 patients were studied. Most patients (307 of 375 [82%] in the retrospective cohort and 244 of 306 [89%] in the prospective cohort) had greater that 80% adherence to their MS medications. Mean inpatient days per patient for MS-related admissions was highest for high-adherence than for intermediate and low-adherence patients (0.52 vs 0.23 and 0.34, respectively; P<.001), but no other associations between adherence and health care utilization were found. Mean outpatient costs and total costs were lowest for the low adherence group, suggesting that higher adherence may not guarantee cost savings overall. Patients with intermediate and high self-reported adherence showed significantly better mean scores than patients with low adherence on several MS outcomes, including EDSS (4.1 and 4.2 vs 4.8, P<.05), MSIS physical function (33 and 35 vs 41, P<.05), and TSQM Global Satisfaction (75 and 78 vs 70, P<.05). Conclusions: The findings of this study indicate that patients with MS are mostly adherent to their existing treatments. Patients with greater medication adherence may have increased cost, but their physical outcomes are better. This finding may shed light on other chronic disease entities and how we view the success of treatments. PMID- 29181517 TI - Musculoskeletal Disorders in Ophthalmologists After Simulated Cataract Operation: A Pilot Study. AB - Context: Musculoskeletal disorders are a common problem among ophthalmologists, likely due to ergonomic challenges. Most research on the topic has been survey based studies, which carry inherent weaknesses. Objective: To examine the frequency and pattern of musculoskeletal dysfunction induced by performing a surgical procedure and to quantify the improvement after ergonomic interventions. Methods: Ophthalmology residents from a single academic institution were invited to participate in the study on a volunteer basis. Preexisting musculoskeletal disorders; previous spinal, cervical, or shoulder surgery; or limited range of motion of the upper body or arms were exclusion criteria. The interventions consisted of a surgical simulation session and a control session, each lasting 2 hours. For the surgical simulation session, a musculoskeletal examination was performed at the beginning and end of the 2-hour session after the participants used the Eyesi Cataract Surgery Simulator (VRmagic). A musculoskeletal examination was performed by the palpatory screener (M.A.Z.) at the beginning and conclusion of the 2-hour control session, which consisted of both passive and active tasks. The musculoskeletal screener was blinded as to which session the participant was completing at the time of the examinations, as well as any musculoskeletal examination findings from before the intervention. All participants completed both sessions, but they were randomized into which session they were to complete first. Participants completed each session one after the other. Results: Eight participants completed both sessions, and 32 musculoskeletal examinations were performed. In the surgical simulation session, after using the simulator, 5 of 8 participants had an increase in the number of spinal levels with tissue texture abnormalities, and 3 had no change. Of those in the control session, 5 participants had a decrease in the number of spinal levels with tissue texture abnormalities after a period of rest. Three participants in the control session had an increase in the number of affected spinal levels. The mean (SD) change in number of affected spinal levels in the surgical simulation session and control session was 1.3 (1.2) and -0.6 (2.0), respectively (P=.125). Age, sex, level of training, baseline somatic dysfunction, and which session was completed first did not affect results. Conclusion: The majority of participants in the surgical simulation session had an increase in degree of somatic dysfunction, whereas the majority in the control session had a decrease in degree of somatic dysfunction. Although the sample size of this pilot study was too small to show statistical significance, a trend was observed, and further study is warranted. PMID- 29181518 TI - Benign Breast Conditions. AB - Breast masses and nipple discharge are common symptoms that lead women to seek medical care. Many of the findings on subsequent examination are benign. When evaluating a patient who presents with breast masses or nipple discharge, it is useful to take a holistic approach to evaluating the patient, including a detailed history, structural and directed physical examination, and, if indicated, laboratory studies, diagnostic imaging, and biopsy. The goal of this review is to assist physicians in understanding the evaluation, diagnosis, and management of benign breast conditions. PMID- 29181519 TI - Role of Antiplatelet Therapy in Stroke Prevention in Patients With Atrial Fibrillation. AB - Patients with atrial fibrillation are at increased risk of having a cardioembolic stroke. The use of oral anticoagulation is now well established to prevent strokes in patients with atrial fibrillation and a CHA2DS2-VASc (congestive heart failure, hypertension, age >=75 years [2 points], diabetes mellitus, prior stroke/transient ischemic attack or thromboembolism [2 points], vascular disease, age 65 to 74 years, and sex category) score of greater than 1, beyond sex. However, the role of antiplatelet therapy, specifically aspirin in low-risk patients or as an alternative to oral anticoagulation, remains controversial. The most recent US guidelines conflict with the European guidelines, which do not recommend antiplatelet monotherapy for stroke prevention irrespective of stroke risk. The aim of this review is to summarize published studies that question the role of aspirin in preventing strokes associated with atrial fibrillation. Overall, aspirin is found to play a limited role in the prevention of stroke in patients with atrial fibrillation and is associated with a similar risk of hemorrhagic events compared with anticoagulants. The benefit of dual antiplatelet therapy as an alternative to oral anticoagulation requires further study. PMID- 29181520 TI - Predictors of Osteopathic Medical Students' Readiness to Use Health Information Technology. AB - Context: The advent of health information technology (HIT) tools can affect the practice of modern medicine in many ways, ideally by improving quality of care and efficiency and reducing medical errors. Future physicians will play a key role in the successful implementation of HIT. However, osteopathic medical students' willingness to learn, adopt, and use technology in a health care setting is not well understood. Objective: To understand osteopathic medical students' knowledge, attitudes, and behaviors regarding HIT and to identify factors that may be related to their readiness to use HIT. Methods: Using a cross sectional approach, quantitative surveys were collected from students attending a large osteopathic medical school. Multivariate regression modeling was used to determine whether knowledge, attitudes, behaviors, and personal characteristics were associated with students' readiness to use HIT in future clinical practice. Results: Six hundred four students responded to at least 70% of the survey and were included in the analysis. Multivariate modeling successfully explained the 26% of variance in predicting students' readiness to use HIT (F8,506=22.6, P<.001, R2=0.263). Greater self-efficacy, openness to change (in academic/work settings), favorable attitudes toward HIT use, mobile technology use, younger age, being male, and prior exposure to technology were associated with readiness to use HIT. Conclusion: Understanding students' level of HIT readiness may help guide medical education intervention efforts to better prepare future osteopathic physicians for HIT engagement and use. Innovative approaches to HIT education in medical school curricula that include biomedical informatics may be necessary. PMID- 29181521 TI - Osteopathic Manipulative Treatment for the Management of Adjacent Segment Pathology. AB - Adjacent segment pathology is an adverse effect of spinal fusion that precipitates accelerated spinal degenerative changes at vertebral segments contiguous with the fused vertebrae. The accelerated degeneration related to ASP can be challenging to manage, as it can lead to conditions such as radiculopathy and can create the need for reoperation. In the present case, a 50-year-old woman with a previous spinal fusion presented with a 1-year history of progressive low back pain, lumbar radiculopathy, and sciatica. Osteopathic manipulative treatment was used to manage her pain, and the patient reported that the treatment provided long-term resolution of her sciatica symptoms. This case demonstrates an effective use of osteopathic manipulative treatment in the conservative management of lumbar radiculopathy related to adjacent segment pathology.

AB - Inguinal hernias containing a kidney or perinephric tissue are extremely rare and usually related to cases involving a kidney positioned in the pelvis. We report the case of a 79-year-old man who presented with abdominal pain and scrotal swelling. He was found on imaging to have an inferiorly displaced kidney with an inguinal herniation of Gerota fascia, as well as an obstructing ureteral stone with an associated forniceal rupture. The unusual renal anatomy, as well as the management of a forniceal rupture, is discussed. PMID- 29181524 TI - Challenging Case of Parotitis: A Comprehensive Approach. AB - The diagnosis and management of parotitis can be challenging. Patients often present with pain and edema in the neck, jaw, head, and ear due to congestion of the gland. Parotitis is typically caused by an infection within the parotid gland and surrounding lymph nodes, and the infection can spread to nearby cervical fascial planes and cause major complications if not managed successfully. Specific guidelines for the outpatient management of parotitis are limited, and outpatient treatment failures are common, requiring inpatient therapy with multiple broad-spectrum antibiotics. In the current case, a comprehensive patient centered approach was used to treat a woman whose overlapping clinical conditions, lifestyle, and work factors led to an infection of the parotid gland.

AB - Importance: A better understanding of the role of cortical structures in blood pressure control may help us understand cardiovascular collapse that may lead to sudden unexpected death in epilepsy (SUDEP). Objective: To identify cortical control sites for human blood pressure regulation. Design, Setting, and Participants: Patients with intractable epilepsy undergoing intracranial electrode implantation as a prelude to epilepsy surgery in the Epilepsy Monitoring Unit at University Hospitals Cleveland Medical Center were potential candidates for this study. Inclusion criteria were patients 18 years or older who had electrodes implanted in one or more of the regions of interest and in whom deep brain electrical stimulation was indicated for mapping of ictal onset or eloquent cortex as a part of the presurgical evaluation. Twelve consecutive patients were included in this prospective case series from June 1, 2015, to February 28, 2017. Main Outcomes and Measures: Changes in continuous, noninvasive, beat-by-beat blood pressure parameter responses from amygdala, hippocampal, insular, orbitofrontal, temporal, cingulate, and subcallosal stimulation. Electrocardiogram, arterial oxygen saturation, end-tidal carbon dioxide, nasal airflow, and abdominal and thoracic plethysmography were monitored. Results: Among 12 patients (7 female; mean [SD] age, 44.25 [12.55] years), 9 electrodes (7 left and 2 right) all in Brodmann area 25 (subcallosal neocortex) in 4 patients produced striking systolic hypotensive changes. Well maintained diastolic arterial blood pressure and narrowed pulse pressure indicated stimulation-induced reduction in sympathetic drive and consequent probable reduction in cardiac output rather than bradycardia or peripheral vasodilation-induced hypotension. Frequency-domain analysis of heart rate and blood pressure variability showed a mixed picture. No other stimulated structure produced significant blood pressure changes. Conclusions and Relevance: These findings suggest that Brodmann area 25 has a role in lowering systolic blood pressure in humans. It is a potential symptomatogenic zone for peri-ictal hypotension in patients with epilepsy. PMID- 29181528 TI - Mutation Spectrum of the LRP5, NDP, and TSPAN12 Genes in Chinese Patients With Familial Exudative Vitreoretinopathy. AB - Purpose: LRP5, NDP, and TSPAN12 are known to be associated with familial exudative vitreoretinopathy (FEVR). In this study, a comprehensive mutation screening for the three genes was performed in patients with a clinical diagnosis of FEVR in Han Chinese. Methods: Genomic DNA and clinical data were collected from 100 probands and their family members. Sanger sequencing was performed to screen for LRP5, NDP, and TSPAN12 mutations and phenotype-genotype correlation was analyzed. Results: There were 23 causative mutations identified in 23 unrelated probands (10/23 in LRP5, 8/23 in TSPAN12, and 5/23 in NDP). Apart from NDP mutations, only two LRP5 mutations inherited in an autosomal recessive manner. Among the 23 causative mutations, 13 were novel variants (4/10 in LRP5, 6/8 in TSPAN12, and 3/5 in NDP). According to the modified classification system, statistical significance was observed in the distribution of mutated genes (P = 0.049). None of the causative mutations was found in group I FEVR. Probands with LRP5 or NDP mutations were mainly categorized into group III and IV, TSPAN12 mutations were mainly observed in probands with group IV and V FEVR. Conclusions: The detection rate for mutations in the three known genes was 23%. Mutations in LRP5 and TSPAN12 were more frequent, accounting for 10% and 8%, respectively. The NDP mutations were only identified in 6% in this cohort. There were 13 novel variants found, which provided a deeper understanding of this disease. Potential phenotype-genotype correlation was observed in the modified system. TSPAN12 mutations might lead to the most severe phenotype.

PMID- 29181530 TI - Neurodevelopmental and Behavioral Outcomes in Extremely Premature Neonates With Ventriculomegaly in the Absence of Periventricular-Intraventricular Hemorrhage. AB - Importance: Studies of cranial ultrasonography and early childhood outcomes among cohorts of extremely preterm neonates have linked periventricular intraventricular hemorrhage and cystic periventricular leukomalacia with adverse neurodevelopmental outcomes. However, the association between nonhemorrhagic ventriculomegaly and neurodevelopmental and behavioral outcomes is not fully understood. Objective: To characterize the outcomes of extremely preterm neonates younger than 27 weeks' gestational age who experienced nonhemorrhagic ventriculomegaly that was detected prior to 36 weeks' postmenstrual age. Design, Setting, and Participants: This longitudinal observational study was conducted at 16 centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Infants born prior to 27 weeks' gestational age in any network facility between July 1, 2006, and June 30, 2011, were included if they had a cranial ultrasonogram performed prior to 36 weeks' postmenstrual age. Comparisons were made between those with ventriculomegaly and those with normal cranial sonograms. Data analysis was completed from August 2013 to August 2017. Main Outcomes and Measures: The main outcome was neurodevelopmental impairment, defined as a Bayley Scales of Infant and Toddler Development III cognitive score less than 70, moderate/severe cerebral palsy, a Gross Motor Function Classification System score of level 2 or more, vision impairment, or hearing impairment. Secondary outcomes included Bayley Scales of Infant and Toddler Development III subscores, components of neurodevelopmental impairment, behavioral outcomes, and death/neurodevelopmental impairment. Logistic regression was used to evaluate the association of ventriculomegaly with adverse outcomes while controlling for potentially confounding variables and center differences as a random effect. Linear regression was used similarly for continuous outcomes. Results: Of 4193 neonates with ultrasonography data, 300 had nonhemorrhagic ventriculomegaly (7%); 3045 had normal cranial ultrasonograms (73%), 775 had periventricular-intraventricular hemorrhage (18.5%), and 73 had cystic periventricular leukomalacia (1.7%). Outcomes were available for 3008 of 3345 neonates with ventriculomegaly or normal scans (90%). Compared with normal cranial ultrasonograms, ventriculomegaly was associated with lower gestational age, male sex, and bronchopulmonary dysplasia, late-onset sepsis, meningitis, necrotizing enterocolitis, and stage 3 retinopathy of prematurity. After adjustment, neonates with ventriculomegaly had higher odds of neurodevelopmental impairment (odds ratio [OR], 3.07; 95% CI, 2.13-4.43), cognitive impairment (OR, 3.23; 95% CI, 2.09-4.99), moderate/severe cerebral palsy (OR, 3.68; 95% CI, 2.08 6.51), death/neurodevelopmental impairment (OR, 2.17; 95% CI, 1.62-2.91), but not death alone (OR, 1.09; 95% CI, 0.76-1.57). Behavioral outcomes did not differ. Conclusions and Relevance: Nonhemorrhagic ventriculomegaly is associated with increased odds of neurodevelopmental impairment among extremely preterm neonates. PMID- 29181532 TI - Management of Suspected Opioid Overdose With Naloxone in Out-of-Hospital Settings: A Systematic Review. AB - Background: Naloxone is effective for reversing opioid overdose, but optimal strategies for out-of-hospital use are uncertain. Purpose: To synthesize evidence on 1) the effects of naloxone route of administration and dosing for suspected opioid overdose in out-of-hospital settings on mortality, reversal of overdose, and harms, and 2) the need for transport to a health care facility after reversal of overdose with naloxone. Data Sources: Ovid MEDLINE (1946 through September 2017), PsycINFO, Cochrane Central Register of Controlled Trials, CINAHL, U.S. Food and Drug Administration (FDA) materials, and reference lists. Study Selection: English-language cohort studies and randomized trials that compared different doses of naloxone, administration routes, or transport versus nontransport after reversal of overdose with naloxone. Main outcomes were mortality, reversal of overdose, recurrence of overdose, and harms. Data Extraction: Dual extraction and quality assessment of individual studies; consensus assessment of overall strength of evidence (SOE). Data Synthesis: Of 13 eligible studies, 3 randomized controlled trials and 4 cohort studies compared different administration routes. At the same dose (2 mg), 1 trial found similar efficacy between higher-concentration intranasal naloxone (2 mg/mL) and intramuscular naloxone, and 1 trial found that lower-concentration intranasal naloxone (2 mg/5 mL) was less effective than intramuscular naloxone but was associated with decreased risk for agitation (low SOE). Evidence was insufficient to evaluate other comparisons of route of administration. Six uncontrolled studies reported low rates of death and serious adverse events (0% to 1.25%) in nontransported patients after successful naloxone treatment. Limitation: There were few studies, all had methodological limitations, and none evaluated FDA approved autoinjectors or highly concentrated intranasal formulations. Conclusion: Higher-concentration intranasal naloxone (2 mg/mL) seems to have efficacy similar to that of intramuscular naloxone for reversal of opioid overdose, with no difference in adverse events. Nontransport after reversal of overdose with naloxone seems to be associated with a low rate of serious harms, but no study evaluated risks of transport versus nontransport.

PMID- 29181534 TI - Association Between Decline in Slow Vital Capacity and Respiratory Insufficiency, Use of Assisted Ventilation, Tracheostomy, or Death in Patients With Amyotrophic Lateral Sclerosis. AB - Importance: The prognostic value of slow vital capacity (SVC) in relation to respiratory function decline and disease progression in patients with amyotrophic lateral sclerosis (ALS) is not well understood. Objective: To investigate the rate of decline in percentage predicted SVC and its association with respiratory related clinical events and mortality in patients with ALS. Design, Setting, and Participants: This retrospective study included 893 placebo-treated patients from 2 large clinical trials (EMPOWER and BENEFIT-ALS, conducted from March 28, 2011, to November 1, 2012, and from October 23, 2012, to March 21, 2014, respectively) and an ALS trial database (PRO-ACT, containing studies completed between 1990 and 2010) to investigate the rate of decline in SVC. Data from the EMPOWER trial (which enrolled adults with possible, probable, or definite ALS; symptom onset within 24 months before screening; and upright SVC at least 65% of predicted value for age, height, and sex) were used to assess the relationship of SVC to respiratory-related clinical events; 456 patients randomized to placebo were used in this analysis. The 2 clinical trials included patients from North America, Australia, and Europe. Main Outcomes and Measures: Clinical events included the earlier of time to death or time to decline in the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) respiratory subdomain, time to onset of respiratory insufficiency, time to tracheostomy, and all-cause mortality. Results: Among 893 placebo-treated patients with ALS, the mean (SD) patient age was 56.7 (11.2) years, and the mean (SD) SVC was 90.5% (17.1%) at baseline; 65.5% (585 of 893) were male, and 20.5% (183 of 893) had bulbar-onset ALS. In EMPOWER, average decline of SVC from baseline through 1.5-year follow-up was -2.7 percentage points per month. Steeper declines were found in patients older than 65 years (-3.6 percentage points per month [P = .005 vs <50 years and P = .007 vs 50-65 years) and in patients with an ALSFRS-R total score of 39 or less at baseline (-3.1 percentage points per month [P < .001 vs >39]). When the rate of decline of SVC was slower by 1.5 percentage points per month in the first 6 months, risk reductions for events after 6 months were 19% for decline in the ALSFRS-R respiratory subdomain or death after 6 months, 22% for first onset of respiratory insufficiency or death after 6 months, 23% for first occurrence of tracheostomy or death after 6 months, and 23% for death at any time after 6 months (P < .001 for all). Conclusions and Relevance: The rate of decline in SVC is associated with meaningful clinical events in ALS, including respiratory failure, tracheostomy, or death, suggesting that it is an important indicator of clinical progression.

AB - Description: The Joint Task Force on Practice Parameters, which comprises representatives of the American Academy of Allergy, Asthma and Immunology (AAAAI) and the American College of Allergy, Asthma and Immunology (ACAAI), formed a workgroup to review evidence and provide guidance to health care providers on the initial pharmacologic treatment of seasonal allergic rhinitis in patients aged 12 years or older. Methods: To update a prior systematic review, the workgroup searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials from 18 July 2012 to 29 July 2016 to identify studies that addressed efficacy and adverse effects of single or combination pharmacotherapy for seasonal allergic rhinitis. In conjunction with the Joint Task Force, the workgroup reviewed the evidence and developed recommendations about initial treatment approaches by using the Grading of Recommendations Assessment, Development and Evaluation approach. Members of the AAAAI, the ACAAI, and the general public provided feedback on the draft document, which the Joint Task Force reviewed before finalizing the guideline. Recommendation 1: For initial treatment of seasonal allergic rhinitis in persons aged 12 years or older, routinely prescribe monotherapy with an intranasal corticosteroid rather than an intranasal corticosteroid in combination with an oral antihistamine. (Strong recommendation). Recommendation 2: For initial treatment of seasonal allergic rhinitis in persons aged 15 years or older, recommend an intranasal corticosteroid over a leukotriene receptor antagonist. (Strong recommendation). Recommendation 3: For treatment of moderate to severe seasonal allergic rhinitis in persons aged 12 years or older, the clinician may recommend the combination of an intranasal corticosteroid and an intranasal antihistamine for initial treatment. (Weak recommendation). PMID- 29181537 TI - A Multivariate Analytic Approach to the Differential Diagnosis of Apraxia of Speech. AB - Purpose: Apraxia of speech (AOS) is a consequence of stroke that frequently co occurs with aphasia. Its study is limited by difficulties with its perceptual evaluation and dissociation from co-occurring impairments. This study examined the classification accuracy of several acoustic measures for the differential diagnosis of AOS in a sample of stroke survivors. Method: Fifty-seven individuals were included (mean age = 60.8 +/- 10.4 years; 21 women, 36 men; mean months poststroke = 54.7 +/- 46). Participants were grouped on the basis of speech/language testing as follows: AOS-Aphasia (n = 20), Aphasia Only (n = 24), and Stroke Control (n = 13). Normalized Pairwise Variability Index, proportion of distortion errors, voice onset time variability, and amplitude envelope modulation spectrum variables were obtained from connected speech samples. Measures were analyzed for group differences and entered into a linear discriminant analysis to predict diagnostic classification. Results: Out-of sample classification accuracy of all measures was over 90%. The envelope modulation spectrum variables had the greatest impact on classification when all measures were analyzed together. Conclusions: This study contributes to efforts to identify objective acoustic measures that can facilitate the differential diagnosis of AOS. Results suggest that further study of these measures is warranted to determine the best predictors of AOS diagnosis. Supplemental Materials: https://doi.org/10.23641/asha.5611309.

PMID- 29181542 TI - Association of Clinician Denial of Patient Requests With Patient Satisfaction. AB - Importance: Prior studies suggesting clinician fulfillment or denial of requests affects patient satisfaction included limited adjustment for patient confounders. The studies also did not examine distinct request types, yet patient expectations and clinician fulfillment or denial might vary among request types. Objective: To examine how patient satisfaction with the clinician is associated with clinician denial of distinct types of patient requests, adjusting for patient characteristics. Design, Setting, and Participants: Cross-sectional observational study of 1319 outpatient visits to family physicians (n = 56) by 1141 adults at one Northern California academic health center. Main Outcomes and Measures: We used 6 Consumer Assessment of Healthcare Providers and Systems Clinician and Group Adult Visit Survey items to measure patient satisfaction with the visit physician. Standardized items were averaged to form the satisfaction score (Cronbach alpha = 0.80), which was then percentile-transformed. Seven separate linear mixed-effects models examined the adjusted mean differences in patient satisfaction percentile associated with denial of each of the following requests (if present)-referral, pain medication, antibiotic, other new medication, laboratory test, radiology test, or other test-compared with fulfillment of the respective requests. The models adjusted for patient sociodemographics, weight, health status, personality, worry over health, prior visit with clinician, and the other 6 request categories and their dispositions. Results: The mean (SD) age of the 1141 patients was 45.6 (16.1) years, and 902 (68.4%) were female. Among 1319 visits, 897 (68.0%) included at least 1 request; 1441 (85.2%) were fulfilled. Requests by category were referral, 294 (21.1%); pain medication, 271 (20.5%); antibiotic, 107 (8.1%); other new medication, 271 (20.5%); laboratory test, 448 (34.0%); radiology test, 153 (11.6%); and other tests, 147 (11.1%). Compared with fulfillment of the respective request type, clinician denials of requests for referral, pain medication, other new medication, and laboratory test were associated with worse satisfaction (adjusted mean percentile differences, 19.75 [95% CI, -30.75 to -8.74], -10.72 [95% CI, -19.66 to -1.78], -20.36 [95% CI, -29.54 to -11.18], and -9.19 [95% CI, -17.50 to -0.87]), respectively. Conclusions and Relevance: Clinician denial of some types of requests was associated with worse patient satisfaction with the clinician, but not for others, when compared with fulfillment of the requests. In an era of patient satisfaction-driven compensation, the findings suggest the need to train clinicians to deal effectively with requests, potentially enhancing patient and clinician experiences. PMID- 29181544 TI - Angiotensin 1-7, but not the thrombin-cleaved osteopontin C-terminal fragment, attenuates osteopontin-mediated macrophage-induced endothelial-cell inflammation. AB - OBJECTIVE AND DESIGN: Evaluating the pro-/anti-inflammatory activity of the C terminal cleavage product of osteopontin in comparison to angiotensin 1-7. MATERIAL AND SUBJECTS: Human coronary endothelial cells (hcEC) treated with conditioned media from human U937 macrophages. TREATMENT: Macrophages were (pre)treated with C-terminal, full-length or N-terminal osteopontin (OPN-C, OPN FL, OPN-N, respectively), angiotensin II, angiotensin 1-7 or TNF-alpha. OPN-C modulatory capacity was compared to that of Ang1-7 in inhibiting subsequent Ag II, OPN-FL or OPN-N-induced macrophage-mediated endothelial inflammation. METHODS: Protein expression of NFkappaB, IkappaB, vCAM-1 and iCAM-1 was assessed using western blot. Promotor activation by NFkappaB was also assessed by dual luciferase reporter assay. RESULTS: Conditioned media of macrophages treated with OPN-C induced hcECs' NfkappaB activation to a lower degree than OPN-FL or OPN-N. Priming of macrophages with angiotensin 1-7 attenuated the endothelial pro inflammatory effect induced by subsequent exposure of the macrophages to angiotensin II, OPN-FL or OPN-N. This was evidenced by both NfkappaB activation and vCAM and iCAM expression. In contrast, priming macrophages with OPN-C did not significantly attenuate the subsequent response to the pro-inflammatory cytokines. CONCLUSIONS: OPN-C induces lower macrophage-induced endothelial inflammation compared to OPN-FL or OPN-N, but unlike angiotensin 1-7, fails to prevent endothelial inflammation induced by subsequent pro-inflammatory macrophage stimulation. PMID- 29181545 TI - Non-celiac gluten sensitivity: people without celiac disease avoiding gluten-is it due to histamine intolerance? AB - INTRODUCTION: Food intolerance/malabsorption is caused by food ingredients, carbohydrates (mainly lactose and fructose), proteins (gluten), and biogenic amines (histamine) which cause nonspecific gastrointestinal and extra-intestinal symptoms. Here we focus on possible etiologic factors of intolerance/malabsorption especially in people with non-celiac gluten sensitivity (NCGS) or the so-called people without celiac disease avoiding gluten (PWCDAG) and histamine intolerance. METHODS: Recognizing the recently described symptoms of NCGS (PWCDAG) we review correlations and parallels to histamine intolerance (HIT). RESULTS: We show that intestinal and extra-intestinal NCGS (PWCDAG) symptoms are very similar to those which can be found in histamine intolerance. CONCLUSIONS: After a detailed diagnostic workup for all possible etiologic factors in every patient, a targeted dietary intervention for single or possibly combined intolerance/malabsorption might be more effective than a short-term diet low in fermentable oligo-, di- and monosaccharides and polyols (FODMAP) or the untargeted uncritical use of gluten-free diets. PMID- 29181546 TI - [Neurolymphomatosis : Two case reports]. PMID- 29181547 TI - Fine-mapping and identifying candidate genes conferring resistance to Soybean mosaic virus strain SC20 in soybean. AB - KEY MESSAGE: The Mendelian gene conferring resistance to Soybean mosaic virus Strain SC20 in soybean was fine-mapped onto a 79-kb segment on Chr.13 where two closely linked candidate genes were identified and qRT-PCR verified. Soybean mosaic virus (SMV) threatens the world soybean production, particularly in China. A country-wide SMV strain system composed of 22 strains was established in China, among which SC20 is a dominant strain in five provinces in Southern China. Resistance to SC20 was evaluated in parents, F1, F2 and the F2:7 RIL (recombinant inbred line) population derived from a cross between Qihuang-1 (resistant) and NN1138-2 (susceptible). The segregation ratio of resistant to susceptible in the populations suggested a single dominant gene involved in the resistance to SC20 in Qihuang-1. A "partial genome mapping strategy" was used to map the resistance gene on Chromosome 13. Linkage analysis between 178 RILs and genetic markers showed that the SC20-resistance gene located at 3.9 and 3.8 cM to the flanking markers BARCSOYSSR_13_1099 and BARCSOYSSR_13_1185 on Chromosome 13. Subsequently, a residual heterozygote segregating population with 346 individuals was developed by selfing four plants heterozygous at markers adjacent to the tentative SC20 resistance gene; then, the candidate region was delimited to a genomic interval of approximately 79 kb flanked by the new markers gm-ssr_13-14 and gm-indel_13-3. Among the seven annotated candidate genes in this region, two genes, Glyma.13G194700 and Glyma.13G195100, encoding Toll Interleukin Receptor nucleotide-binding-leucine-rich repeat resistance proteins were identified as candidate resistance genes by quantitative real-time polymerase chain reaction and sequence analysis. The two closely linked genes work together to cause the phenotypic segregation as a single Mendelian gene. These results will facilitate marker-assisted selection, gene cloning and breeding for the resistance to SC20. PMID- 29181548 TI - Non-driver mutations in patients with JAK2V617F-mutated polycythemia vera or essential thrombocythemia with long-term molecular follow-up. AB - JAK2V617F monitoring and NGS of non-driver genes was performed in 100 patients with polycythemia vera (PV) or essential thrombocythemia (ET) with long molecular follow-up. Patients who did not progress to myelofibrosis (MF) or acute myeloid leukemia (AML) after more than 10 years (n = 50) showed a low frequency of mutations at first sample (18%) and an incidence rate of 1.7 new mutations * 100 person-years. Mutations were detected at first sample in 83% of PV/ET patients who later progressed to AML (n = 12) with these patients having a rate of 25.6 mutations * 100 person-years. Presence of mutations at diagnosis was the unique risk factor for acquiring a new genetic event (HR 2.7, 95% CI 1.1-6.8, p = 0.03) after correction for age, PV diagnosis, and total duration of hydroxyurea (HU) exposure. Patients with additional mutation at first sample showed a higher probability of developing cytopenia under HU therapy and a higher risk of AML (HR 12.2, 95% CI 2.6-57.1, p = 0.001) with mutations in ASXL1 (p < 0.0001), TP53 (p = 0.01), SRSF2 (p < 0.0001), IDH1/2 (p < 0.0001), and RUNX1 (p < 0.0001) being associated with a higher probability of AML. Myelofibrotic transformation was more frequent in patients with additional mutations, especially in SF3B1 (p = 0.02) and IDH1/2 (p < 0.0001) although a persistently high or a progressive increase of the JAK2V617F allele burden while receiving cytoreduction was the strongest predictor of MF transformation (HR 10.8, 95% CI 2.4-49.1, p = 0.002). In conclusion, NGS may be useful to identify a minority of PV and ET patients with high genetic instability and increased risk of AML transformation. PMID- 29181549 TI - Treating open lower limb fractures successfully; thoughts and current practice on therapy and centralization in The Netherlands. AB - INTRODUCTION: The British Orthopedic Association (BOA) and British Association of Plastic, Reconstructive and Aesthetic Surgeons (BAPRAS) updated the evidence based guidelines for the treatment and care of open lower limb fractures (BOAST 4). Following this, a Dutch version has been developed. The main points are multidisciplinary care, planning, and treatment of these injuries. Early osteosynthesis (within 7-14 days) combined with soft-tissue coverage results in more efficient care and less complications. AIM: To study the variation in treatment and thoughts among trauma, orthopedic, and plastic surgeons. MATERIALS AND METHODS: In this cross-sectional study 94 surgeons (57 trauma, 23 plastic, and 14 orthopedic surgeons) working at 46 centers completed an online questionnaire, consisting of 5 demographic, 14 hospital-related, 8 BOAST 4 related, and 2 centralization-related questions. RESULTS: There was a strong agreement among surgeons about the best moment for multidisciplinary consultation, which was before initial debridement, while in practice, this often does not occur. All surgeons agreed that the initial debridement should be performed immediately by any surgeon, but not solely by trainees. Plastic surgeons responded that the definitive stabilization and wound cover should not exceed 7 days, while half of the trauma and orthopedic surgeons agreed that it should not exceed 14 days. Finally, most surgeons agreed that Gustilo 3 fractures should be centralized. However, there was disagreement on the need for centralization of Gustilo 2 fractures. DISCUSSION: Surgeons agree on better and earlier multidisciplinary treatment of open lower limb fractures and the centralization of Gustilo 3 fractures. PMID- 29181550 TI - Intravesical hyaluronic acid and chondroitin sulfate for recurrent urinary tract infections: systematic review and meta-analysis. AB - INTRODUCTION AND HYPOTHESIS: The objective was to assess the efficacy of intravesical hyaluronic acid (HA) and chondroitin sulfate (CS), alone or in combination, for recurrent urinary tract infections (RUTIs) in adult female patients using a systematic review and meta-analysis. METHODS: English-language articles were obtained from the MEDLINE, Embase, and Cochrane databases through November 2016, by manual searching and cross-referencing. Randomized and nonrandomized trials of adult female patients with a documented history of RUTIs who received HA, CS or HA plus CS were included. The random effects model was applied to all pooled analyses. Risk of bias was assessed for individual studies and across studies. RESULTS: Two randomized (n = 85) and six nonrandomized (n = 715) studies met the inclusion criteria. These studies assessed HA +/- CS; studies of CS alone were not identified in the search. HA +/- CS decreased the UTI rate per patient-year (pooled mean difference [MD] -2.56; 95% confidence interval [CI] -3.86, -1.26; p < 0.001) and increased the time to first UTI recurrence (pooled MD 130.05 days; 95% CI 5.84, 254.26; p = 0.04). There was heterogeneity in most outcomes considered, and publication bias in many studies. The standard of trial reporting was low. The patient population size, and the number of studies included, were small. CONCLUSIONS: HA +/- CS appears to reduce the rate of UTI and increase the time to recurrence in women with RUTI. As randomized controlled studies are available only for HA plus CS, the quality of evidence is higher for the combination than for HA alone. PMID- 29181551 TI - [Metabolic disorders as paraneoplastic syndromes]. AB - Paraneoplastic syndromes are characterized by the tumor-induced release of peptide hormones and/or the initiation of immune phenomena, which elicit clinical changes and alterations in laboratory parameters independent of the tumor size and spread. In addition to neurological, endocrinal and rheumatological phenotypes, metabolic alterations play a special role in the clinical routine as they commonly present with acute symptoms in an emergency situation and necessitate immediate diagnosis and prompt initiation of treatment. Metabolic alterations within the framework of malignant diseases should be treated in a multidisciplinary team and it is often necessary to perform monitoring and treatment in an intensive care unit. This article focuses on the diagnostic and therapeutic options for metabolic disorders due to paraneoplastic syndromes, such as hypercalcemia, hypocalcemia, hyperglycemia, hypoglycemia and a special variant of tumor-induced metabolic disorders due to tumor lysis syndrome. PMID- 29181552 TI - [Nephrotic syndrome and microhematuria in a patient with nutcracker syndrome: Report of a case and review of the literature]. AB - We report about a 43-year-old woman with polyvalent drug addiction (i.e. alcohol, nicotine, methadone maintenance program with parallel consumption of heroin) who presented to the emergency department with peripheral edema, generalized weakness, and arthralgia. Laboratory findings revealed, among others, proteinuria, hyperlipoproteinemia and hypoproteinemia defining nephrotic syndrome. Computed tomography of the abdomen and iliocavography further revealed compression of left renal vein between aorta and superior mesenteric artery with distention of left ovarian vein as a possible cause of nephrotic syndrome (i. e. nutcracker syndrome). After excluding other possible causes of nephrotic syndrome, we decided against an interventional procedure due to poor compliance of the patient and potential risk of secondary stent dislocation. Instead, we opted for a surgical approach (i. e. veno-venous bypass, meaning transposition of left vena ovarica on vena cava inferior). The operative and postoperative course was uneventful. Postoperatively, proteinuria, microhematuria, arthralgia and edema receded. PMID- 29181553 TI - [CAREFul-care programme for the last days of life]. PMID- 29181554 TI - [Cardiological functional diagnostics]. AB - Cardiovascular diseases are common; therefore, adequate and guideline-based diagnostics and treatment are essential. In addition to an electrocardiogram (ECG) and (treadmill) exercise tests, echocardiography plays the pivotal role in functional cardiac testing. It is permanently available at the bedside and has a high diagnostic accuracy; however, examinations such as cardiac magnetic resonance imaging (MRI) and computed tomography (CT) as well as nuclear medical imaging, e.g. single proton emission CT (SPECT) and positron emission tomography (PET) are becoming more and more common in clinical practice. This is due to the wide range of additional information and the high diagnostic accuracy. In the following article, the individual possibilities of non-invasive cardiac functional testing are presented and their meaningful application will be discussed; however, studies on the meaningful application of non-invasive diagnostics are scarce. PMID- 29181555 TI - Predicting vection and visually induced motion sickness based on spontaneous postural activity. AB - Evidence is mounting that differences in postural instability can be used to predict who will experience strong illusory self-motions (vection) and become sick when exposed to global patterns of optical flow (e.g., Apthorp et al., PLoS One 9(12):e113897, 2014; Stoffregen and Smart, Brain Res Bull 47:437-448, 1998). This study compared the predictive ability of traditional and recurrence quantification analysis (RQA) based measures of postural activity. We initially measured spontaneous fluctuations in the centre of foot pressure (CoP) of our subjects as they stood quietly with their eyes open and closed. They were then repeatedly exposed to two different types of self-motion display. As expected, the oscillating self-motion displays were found to induce stronger vection and greater sickness than the smooth self-motion displays. RQA based measures of spontaneous postural activity proved to be superior predictors of both vection strength and visually induced motion sickness (VIMS). Participants who had displayed lower CoP recurrence rates when standing quietly were more likely to later report stronger vection and VIMS when exposed to both types of optical flow. Vection strength (but not VIMS) was also found to correlate significantly with three other RQA based measures of postural activity (determinism, entropy, and average diagonal line length). We propose that these RQA based measures of spontaneous postural activity could serve as useful diagnostic tools for evaluating who will benefit the most/least from exposure to virtual environments. PMID- 29181556 TI - Oligometastases in prostate cancer : Metabolic response in follow-up PSMA-PET-CTs after hypofractionated IGRT. AB - BACKGROUND: Prostate-specific membrane antigen positron emission tomography/computed tomography (PSMAPET/CT) is a new and evolving diagnostic method in prostate cancer with special impact on treatment planning in image guided radiotherapy (IGRT). Initial results of metabolic response in repeated PSMA PET/CTs after hypofractionated IGRT for metastatic lesions are reported here. MATERIALS AND METHODS: Of 280 patients investigated with 68Ga-PSMA PET/CT in the period from 01/2014 through 12/2016 in the authors' department, patients were selected according to the following criteria: oligometastatic disease at initial PSMA PET/CT defined as not more than five metastatic lesions, hypofractionated IGRT to all lesions, no systemic therapy in the last 6 months and during follow-up, and at least one follow-up PSMA PET after radiotherapy. Radiotherapy was administered to all PSMA PET-detected lesions (CTV = PET-GTV + 1 to 2 mm), mostly with 35 Gy in five fractions (one lesion with four fractions of 7 Gy due to dose constraints, two lymph nodes with 50 Gy in 25 fractions to an extended volume plus a boost of 7 Gy * 2 to the PET-positive volume). Metabolic response of irradiated lesions was evaluated on repeated PSMA PET/CTs according to PERCIST criteria. Five patients with a total number of 12 PSMA PETs matched the criteria. Patients received radiotherapy to all PET-positive lesions and had at least one (in one case three) follow-up PSMA PET examinations after radiotherapy with an interval to the first PET of 2-15 months; the median follow up for all patients was 11 months. RESULTS: The mean prostate-specific antigen (PSA) values at the time of examination were 8.9 +/- 8.5 ng/ml (median 3.3 ng/ml, range 0.17-21.8 ng/ml). A total number of 18 metastatic deposits were detected. The PET-positive tumor volume was 5.9 +/- 13.3 cm3 (median 1.25 cm3). The mean standardized uptake value (mean SUVmax) of the 18 metastatic lesions decreased from 19.9 +/- 23.3 (mean +/- SD) prior to RT to 5.4 +/- 4.6 at post-radiotherapy PSMA PET/CT. Using PERCIST criteria, 14 lesions (78%) showed a metabolic response in PSMA PET with a reduction of SUV of at least 30%, as well as a significant decrease in lesion size; in seven of these lesions, no uptake of 68Ga-PSMA was detectable. In follow-up PET scans, only two lesions showed metabolic progression with an increase in SUVmax yielding a local progression-free survival of 88% after 1 year. There was a correlation between the time interval after radiotherapy (median 3 months, range 1-9 months) and response (p = 0.04) with better metabolic response after longer follow-up. CONCLUSIONS: Preliminary results of this study show high metabolic response rates of PSMA PET-positive metastatic lesions after hypofractionated radiotherapy in follow-up PSMA PET with promising local control rates. An interval of several months may be required to fully estimate the efficacy of radiotherapy in control PSMA PET. PMID- 29181559 TI - Compensation after treatment for anterior cruciate ligament injuries: a review of compensation claims in Norway from 2005 to 2015. AB - PURPOSE: To assess the most common reasons for complaints following anterior cruciate ligament (ACL) injuries reported to the Norwegian System of Patient Injury Compensation (NPE), and to view these complaints in light of the ACL reconstructions (ACL-Rs) reported to the Norwegian Knee Ligament Registry (NKLR). METHOD: Data from the NPE and the NKLR were collected for the study period (2005 2015). The age and gender and type of complaint and reason for granted compensation were collected from the NPE, while the graft choice and total number of ACL-R were collected from the NKLR. Risk for successful grant was estimated for graft type. RESULTS: 18,810 primary ACL-Rs were reported to the NKLR during the study period. A hamstring graft was used in 12,437 (66.1%) but the bone patellar tendon-bone (BPTB) became the graft of choice at the end of the study period. 240 patients filed a complaint to the NPE, of which 101 were granted compensation. The odds ratio for a claim being granted following a hamstring graft was 2.9 compared to that of a BPTB graft (p = 0.002) The most common reason for compensation was a hospital-acquired infection in 39 patients (38.6%) followed by inadequate surgical technique (27, 26.7%) and delayed diagnosis (13, 12.9%). Of the 39 patients with infection, 27 had received a hamstring graft and six a BPTB graft (two patients were not reconstructed, data missing for three patients). Of the 27 patients who were granted compensation due to inadequate surgical technique, 24 had received a hamstring graft and three a BPTB graft. CONCLUSION: Infection and inadequate surgical technique are the most common causes for granted compensation from the NPE following ACL injury. Hamstring grafts have a threefold risk of complication that yields compensation from the NPE compared to BPTB grafts. This information is relevant for patients and surgeons when choosing graft type. The trend of increased use of BPTB grafts is warranted based on the results from this study. LEVEL OF EVIDENCE: Level III. PMID- 29181558 TI - Internal-external malalignment of the femoral component in kinematically aligned total knee arthroplasty increases tibial force imbalance but does not change laxities of the tibiofemoral joint. AB - PURPOSE: The purposes of this study were to quantify the increase in tibial force imbalance (i.e. magnitude of difference between medial and lateral tibial forces) and changes in laxities caused by 2 degrees and 4 degrees of internal-external (I-E) malalignment of the femoral component in kinematically aligned total knee arthroplasty. Because I-E malalignment would introduce the greatest changes to the articular surfaces near 90 degrees of flexion, the hypotheses were that the tibial force imbalance would be significantly increased near 90 degrees flexion and that primarily varus-valgus laxity would be affected near 90 degrees flexion. METHODS: Kinematically aligned TKA was performed on ten human cadaveric knee specimens using disposable manual instruments without soft tissue release. One 3D-printed reference femoral component, with unmodified geometry, was aligned to restore the native distal and posterior femoral joint lines. Four 3D-printed femoral components, with modified geometry, introduced I-E malalignments of 2 degrees and 4 degrees from the reference component. Medial and lateral tibial forces were measured from 0 degrees to 120 degrees flexion using a custom tibial force sensor. Bidirectional laxities in four degrees of freedom were measured from 0 degrees to 120 degrees flexion using a custom load application system. RESULTS: Tibial force imbalance increased the greatest at 60 degrees flexion where a regression analysis against the degree of I-E malalignment yielded sensitivities (i.e. slopes) of 30 N/ degrees (medial tibial force > lateral tibial force) and 10 N/ degrees (lateral tibial force > medial tibial force) for internal and external malalignments, respectively. Valgus laxity increased significantly with the 4 degrees external component with the greatest increase of 1.5 degrees occurring at 90 degrees flexion (p < 0.0001). CONCLUSION: With the tibial component correctly aligned, I-E malalignment of the femoral component caused significant increases in tibial force imbalance. Minimizing I-E malalignment lowers the increase in the tibial force imbalance. By keeping the resection thickness of each posterior femoral condyle to within +/- 0.5 mm of the thickness of the respective posterior region of the femoral component, the increase in imbalance can be effectively limited to 38 N. Generally laxities were unaffected within the +/- 4o range tested indicating that instability is not a clinical concern and that manual testing of laxities is not useful to detect I-E malalignment. PMID- 29181560 TI - Stability and alignment do not improve by using patient-specific instrumentation in total knee arthroplasty: a randomized controlled trial. AB - PURPOSE: The primary aim of the study was to examine stability and alignment after total knee arthroplasty (TKA) using patient-specific instrumentation (PSI) and conventional instrumentation (CI). The hypothesis was that stability and alignment would be better using PSI than CI, 12 months postoperatively. The secondary aim included the evaluation of clinical outcomes after TKA. METHODS: In this prospective randomized controlled trial, 42 patients with knee osteoarthritis received a Genesis II PS prosthesis with either PSI or CI. Patients visited the hospital preoperatively and postoperatively after 6 weeks and 3 and 12 months. To evaluate stability, varus-valgus laxity was determined in extension and flexion using stress radiographs 12 months postoperatively. Three months postoperatively, a long-leg radiograph and CT scan were obtained to measure hip-knee-ankle (HKA) alignment and component rotation. Furthermore, frontal and sagittal alignment of the components, the Knee Society Score, VAS Pain, VAS Satisfaction, Knee injury and Osteoarthritis Outcome score, Patella score (Kujala), University of California Los Angeles activity score, anterior posterior laxity, (serious) adverse device-related events, and intraoperative complications were reported. The clinical outcomes were compared using independent t tests or non-parametric alternatives, and repeated measurements ANOVA with a significance level of p < 0.05. RESULTS: No significant differences were found between the two groups regarding stability, HKA angle, and rotational alignment. In four patients, the PSI did not fit correctly on the tibia and/or femur requiring intraoperative modifications. Both groups improved significantly over time on all clinical outcomes, with no significant differences between the groups 12 months postoperatively. The PSI group showed less tibial slope than the patients in the CI group [PSI 2.6 degrees versus CI 4.8 degrees (p = 0.02)]. Finally, the PSI group more frequently received a thinner insert size than the CI group (p = 0.03). CONCLUSIONS: Patients operated with PSI did not differ from CI in terms of stability and alignment. However, in the PSI group ligament releases were more often required intraoperatively. Furthermore, the two methods did not show different clinical results. It seems that the preoperative planning for the PSI facilitates more conservative bone cuts than CI, but whether this is clinically relevant should be investigated. Since PSI is more expensive and time consuming than CI, and does not outperform CI with regard to clinical results, we recommend to use CI. LEVEL OF EVIDENCE: I. PMID- 29181561 TI - Humeral lengthening and proximal deformity correction with monorail external fixator in young adults. AB - PURPOSE: Several humeral lengthening or simultaneous deformity corrections through one osteotomy using various external fixators were reported, while literature regarding correction of shortening and proximal varus deformity is scarce. This retrospective clinical study evaluated the results of preforming an acute correction and delayed lengthening in young adults through two osteotomies using monorail external fixator. METHODS: We report seven patients with various pathologies who underwent humeral proximal deformity correction and lengthening between 2009 and 2015. Pre-operative and post-operative clinical and radiographic data were collected. The mean follow-up time was 33.4 months (25-46 months). RESULTS: The humeral neck-shaft angle improved from 97.9 degrees (85-110 degrees ) to 138.6 degrees (135-145 degrees ). The magnitude of lengthening achieved was average 7.6 cm (range, 6-10 cm) at an average healing index of lengthening of 30.2 days/cm (range, 27.7-35.4 days/cm). There was a significant increase in range of shoulder abduction, and active abduction improved from pre-operative 136.4 degrees (range, 95-160 degrees ) to post-operative 166.4 degrees (range, 150-180 degrees ). The DASH score improved significance from 23.29 +/- 8.36 to 6.57 +/- 3.65 (t = 4.848; p < 0.001). CONCLUSION: Acute deformity correction and gradual lengthening with the monorail external fixator can be used for humeral shortening and proximal varus angular deformity. Functional improvement is expected after surgery and post-operative therapy.

AB - PURPOSE: Critically ill patients are exposed to stressful conditions and experience several discomforts. The primary objective was to assess whether a tailored multicomponent program is effective for reducing self-perceived discomfort. METHODS: In a cluster-randomized two-arm parallel trial, 34 French adult intensive care units (ICUs) without planned interventions to reduce discomfort were randomized, 17 to the arm including a 6-month period of program implementation followed by a 6-month period without the program (experimental group), and 17 to the arm with an inversed sequence (control group). The tailored multicomponent program consisted of assessment of ICU-related self-perceived discomforts, immediate and monthly feedback to healthcare teams, and site specific tailored interventions. The primary outcome was the overall discomfort score derived from the 16-item IPREA questionnaire (0, minimal, 100, maximal overall discomfort) and the secondary outcomes were the discomfort scores of each IPREA item. IPREA was administered on the day of ICU discharge with a considered timeframe from the ICU admission until ICU discharge. RESULTS: During a 1-month assessment period, 398 and 360 patients were included in the experimental group and the control group, respectively. The difference (experimental minus control) of the overall discomfort score between groups was - 7.00 (95% CI - 9.89 to - 4.11, p < 0.001). After adjustment (age, gender, ICU duration, mechanical ventilation duration, and type of admission), the program effect was still positive for the overall discomfort score (difference - 6.35, SE 1.23, p < 0.001) and for 12 out of 16 items. CONCLUSIONS: This tailored multicomponent program decreased self-perceived discomfort in adult critically ill patients. TRIAL REGISTRATION: Clinicaltrials.gov Identifier NCT02442934.

PMID- 29181563 TI - Final kissing balloon inflation for coronary bifurcation lesions treated with single-stent technique : A meta-analysis. AB - BACKGROUND: The efficacy of final kissing balloon (FKB) inflation in one-stent techniques for bifurcation lesions is controversial. The goal of the present study was to investigate the impact of FKB on long-term clinical outcomes in one stent strategies. METHODS: A literature search of the PubMed, Embase, and Cochrane Library databases was undertaken through August 2017. The primary outcome was major adverse cardiac events (MACE), defined as the composite of cardiac death, myocardial infarction, and target lesion revascularization. Overall hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using the random-effects model. RESULTS: Ten studies comprising 7364 patients treated with a one-stent technique were included in the analysis. Overall, FKB did not demonstrate a significant reduction in MACE compared with non-FKB in both randomized trials (HR: 1.13; 95% CI: 0.65-1.98) and observational studies (HR: 0.86; 95% CI: 0.61-1.20). The risk of cardiac death (HR: 0.89; 95% CI: 0.53 1.49), myocardial infarction (HR: 0.76; 95% CI: 0.53-1.09), and target lesion revascularization (HR: 0.96; 95% CI: 0.74-1.23) was also similar in both groups. CONCLUSION: FKB may not be mandatory and a selective FKB strategy might be more justified in one-stent techniques for bifurcation lesions. PMID- 29181564 TI - A cadaver study into the number of fasciotomies required to decompress the anterior compartment in forearm compartment syndrome. AB - PURPOSE: There is no typical approach for decompression of forearm compartment syndrome, due to contradictory considerations regarding the characteristics of forearm anterior compartment deep fascia. The main purpose of this study was to determine how many fasciae should be opened to fully decompress the forearm anterior compartment. Further, the compliance of the deep anterior compartment was also investigated, to strengthen our results. METHODS: An experimental study of a laboratory model of acute forearm compartment syndrome was performed. A deep forearm injection of egg white was undertaken to create an acute forearm compartment syndrome in sixteen non-embalmed human forearms from six male and two female donors. The pressure in the superficial and deep anterior compartments was recorded four times, both before and after each fasciotomy and the compliance of the deep anterior compartment was calculated for each step. RESULTS: The first incision of the superficial lamina of the deep fascia was not sufficient to decrease the elevated compartment pressure in the superficial and deep anterior compartments. Whereas the pressures decreased to near-baseline levels, following the fasciotomy of the intermuscular septum observed posterior to the flexor carpi radialis. The last incision of the deep lamina of the deep anterior fascia had no noticeable impact. These observations supported the hypothesis of high compliance of the deep anterior compartment. CONCLUSION: Two successive incisions were necessary to decompress the anterior compartment: the incision of the superficial lamina of the deep fascia and the incision of the intermuscular septum. PMID- 29181565 TI - Postnatal myocardium remodelling generates inhomogeneity in the architecture of the ventricular mass. AB - BACKGROUND: The 3D architecture of the ventricular mass is poorly known, although in vivo imaging techniques show the physiological inhomogeneity of ventricular walls mechanics. Polarized light imaging makes it possible to quantitatively analyse the myosin filament orientation. AIMS: In this paper, we focus on the study the 3D architecture and regional isotropy of myocardial cells. METHODS: Twenty normal human hearts, 10 from the perinatal period and 10 from the post neonatal period were studied by polarized light microscopy. In each voxel of the ventricular mass (90 * 90 * 500 um) the principal orientation segment was automatically and unambiguously extracted as well as a regional isotropy index (regional orientation tensor of the voxel neighbourhood). RESULTS: During the first months of postnatal age, the median regional isotropy values decreased in the ventricular mesh. This global decrease was not homogeneous across the ventricular walls. From the perinatal to the neonatal period, this decrease was more marked in the inner two-third of the lateral left ventricular wall and in the right part of the interventricular septum. There was a progressive post neonatal appearance of a particularly inhomogeneous secondary arrangement of myocardial cells with alternation of thick low-RI and thin high-RI areas. CONCLUSIONS: This study has shown a postnatal change in ventricular myocardial architecture, which became more inhomogeneous. The cell rearrangements responsible for the inhomogeneity in ventricular myocardial architecture are revealed by a variation of the regional isotropy index. These major changes are probably an adaptive consequence of the major haemodynamic changes occurring after birth during the neonatal period that generates major parietal stress variations and parietal remodelling. PMID- 29181567 TI - From molecular engineering to process engineering: development of high-throughput screening methods in enzyme directed evolution. AB - With increasing concerns in sustainable development, biocatalysis has been recognized as a competitive alternative to traditional chemical routes in the past decades. As nature's biocatalysts, enzymes are able to catalyze a broad range of chemical transformations, not only with mild reaction conditions but also with high activity and selectivity. However, the insufficient activity or enantioselectivity of natural enzymes toward non-natural substrates limits their industrial application, while directed evolution provides a potent solution to this problem, thanks to its independence on detailed knowledge about the relationship between sequence, structure, and mechanism/function of the enzymes. A proper high-throughput screening (HTS) method is the key to successful and efficient directed evolution. In recent years, huge varieties of HTS methods have been developed for rapid evaluation of mutant libraries, ranging from in vitro screening to in vivo selection, from indicator addition to multi-enzyme system construction, and from plate screening to computation- or machine-assisted screening. Recently, there is a tendency to integrate directed evolution with metabolic engineering in biosynthesis, using metabolites as HTS indicators, which implies that directed evolution has transformed from molecular engineering to process engineering. This paper aims to provide an overview of HTS methods categorized based on the reaction principles or types by summarizing related studies published in recent years including the work from our group, to discuss assay design strategies and typical examples of HTS methods, and to share our understanding on HTS method development for directed evolution of enzymes involved in specific catalytic reactions or metabolic pathways.

PMID- 29181569 TI - Characterization of oligotrophic AnAOB culture: morphological, physiological, and ecological features. AB - Anaerobic ammonium oxidation (anammox) process is regarded as a promising nitrogen removal technology to treat ammonium wastewaters in a wide concentration range. Oligotrophic anaerobic ammonia oxidation bacteria (O-AnAOB) culture has been successfully achieved from a new anammox system to treat superlow ammonium concentration wastewaters. In this work, the O-AnAOB culture was compared with the eutrophic AnAOB (E-AnAOB) culture to reveal its physiological, morphological, and ecological features. Results showed that the specific anammox activity (SAA) of O-AnAOB culture was 0.07 kgN/(kgVSS.d) with the nitrogen removal rate (NRR) of 0.20 kgN/ (m3 d) in the reactor, while the SAA of E-AnAOB culture was 2.11 kgN/(kgVSS.d) with the NRR of 11.10 kgN/(m3 d). The hzs gene transcription levels (hzs-mRNA) of O-AnAOB and E-AnAOB cultures were 1.32 * 109 copies/gVSS and 1.51 * 1010 copies/gVSS, respectively. Morphologically, the O-AnAOB culture took on the unique brown color rather than the typical red color of E-AnAOB. The O-AnAOB cells lived in a disperse pattern in the culture. The cells were seriously deformed with deep craters on the cell wall. The size of anammoxsome and paryphoplasm compartments inside the O-AnAOB cells was smaller than that inside the E-AnAOB cells. Ecologically, the O-AnAOB culture had special microbial community with a higher bacterial diversity than the E-AnAOB. The most dominant genera in O-AnAOB were Anaerolineaceae (33.7%, fermentative bacteria), Candidatus Kuenenia (17.4%, anammox bacteria), and Nitrospira (7.3%, nitrite oxidizing bacteria). This study provided an insight into the new anammox process for deep nitrogen removal from wastewaters. PMID- 29181570 TI - Improved production of dibenzocyclooctadiene lignans in the elicited microshoot cultures of Schisandra chinensis (Chinese magnolia vine). AB - Dibenzocyclooctadiene lignans are a specific group of secondary metabolites that occur solely in Schisandra chinensis. The aim of the presented work was to boost the accumulation of lignans in the agitated microshoot cultures of S. chinensis, using different elicitation schemes. The experiments included testing of various concentrations and supplementation times of cadmium chloride (CdCl2), chitosan (Ch), yeast extract (YeE), methyl jasmonate (MeJa), and permeabilizing agent dimethylsulfoxide (DMSO). After 30 days, the microshoots were harvested and evaluated for growth parameters and lignan content by LC-DAD method. The analyses showed enhanced production of lignans in the elicited S. chinensis microshoots, whereas the respective media samples contained only trace amounts of the examined compounds (< 5 mg/l). Elicitation with CdCl2 caused up to 2-fold increase in the total lignan content (max. ca. 730 mg/100 g DW after the addition of 1000 MUM CdCl2 on the tenth day). Experiments with chitosan resulted in up to 1.35-fold increase in lignan concentration (max. ca. 500 mg/100 g DW) after the supplementation with 50 mg/l on the first day and 200 mg/l on the tenth day. High improvement of lignan production was also recorded after YeE elicitation. After the elicitation with 5000 mg/l of YeE on the first day of the growth period, and with 1000 and 3000 mg/l on the 20th day, the lignan production increased to the same degree-about 1.8-fold. The supplementation with 1000 mg/l YeE on the 20th day of the growth cycle was chosen as the optimal elicitation scheme, for the microshoot cultures maintained in Plantform temporary immersion system-the total content of the estimated lignans was equal to 831.6 mg/100 g DW.

AB - PURPOSE: The relationship between biomechanical instability and degenerative changes in the lumbar spine in chronic low back pain (CLBP) patients remains controversial. The main objective of this retrospective radiographical study was to evaluate changes in kinematics at different lumbar levels (in particular the L5-S1 level) with progressive grades of disc degeneration and facet joint osteoarthritis in CLBP patients. METHODS: Using standing neutral and dynamic flexion/extension (Fx/Ex) radiographs of the lumbar spine, in vivo segmental kinematics at L1-L2 through L5-S1 were evaluated in 72 consecutive CLBP patients. Disc degeneration was quantified using changes in signal intensity and central disc height on mid-sagittal T2-weighted magnetic resonance (MR) scans. Additionally, the presence or absence of facet joint osteoarthritis was noted on T2-weighted axial MR scans. RESULTS: Disc degeneration and facet joint osteoarthritis occurred independent of each other at the L5-S1 level (p = 0.188), but an association was observed between the two at L4-L5 (p < 0.001) and L3-L4 (p < 0.05) levels. In the absence of facet joint osteoarthritis, the L5-S1 segment showed a greater range of motion (ROM) in Ex (3.3 degrees +/- 3.6 degrees ) and a smaller ROM in Fx (0.6 degrees +/- 4.2 degrees ) compared with the upper lumbar levels (p < 0.05), but the differences diminished in the presence of it. In the absence of facet joint osteoarthritis, no change in L5-S1 kinematics was observed with progressive disc degeneration, but in its presence, restabilisation of the L5-S1 segment was observed between mild and severe disc degeneration states. CONCLUSION: The L5-S1 motion segment exhibited unique degenerative and kinematic characteristics compared with the upper lumbar motion segments. Disc degeneration and facet joint osteoarthritis occurred independent of each other at the L5-S1 level, but not at the other lumbar levels. Severe disc degeneration in the presence of facet joint osteoarthritis biomechanically restabilised the L5-S1 motion segment.

PMID- 29181576 TI - Expression profile of microRNA-146a along HPV-induced multistep carcinogenesis: a study in HPV16 transgenic mice. AB - PURPOSE: Persistent human papillomavirus (HPV) infection is associated with the development of certain types of cancer and the dysregulation of microRNAs has been implicated in HPV-associated carcinogenesis. This is the case of microRNA 146a (miR-146a), which is thought to regulate tumor-associated inflammation. We sought to investigate the expression levels of miR-146a during HPV16-mediated carcinogenesis using skin samples from K14-HPV16 transgenic mice which develop the consecutive phases of the carcinogenesis process. METHODS: Female transgenic (HPV+/-) and wild-type (HPV-/-) mice were sacrificed at 24-26 weeks-old or 28-30 weeks-old. Chest and ear skin samples from HPV+/- and HPV-/- mice were histologically classified and used for microRNA extraction and quantification by qPCR. RESULTS: Chest skin samples from 24 to 26 weeks-old HPV+/- mice presented diffuse epidermal hyperplasia and only 22.5% showed multifocal dysplasia, while at 28-30 weeks-old all (100.0%) HPV+/- animals showed epidermal dysplasia. All HPV+/- ear skin samples showed carcinoma in situ (CIS). MiR-146a expression levels were higher in HPV+/- compared to HPV-/- mice (p = 0.006). There was also an increase in miR-146a expression in dysplastic skin lesions compared with hyperplasic lesions (p = 0.011). Samples showing CIS had a significant decrease in miR-146a expression when compared to samples showing epidermal hyperplasia (p = 0.018) and epidermal dysplasia (p = 0.009). CONCLUSIONS: These results suggest that HPV16 induces the overexpression of miR-146a in the initial stages of carcinogenesis (hyperplasia and dysplasia), whereas decreases its expression at later stages (CIS). Taken together, these data implicate and suggest different roles of miR-146a in HPV-mediated carcinogenesis. PMID- 29181579 TI - Mediterranean diet: fresh herbs and fresh vegetables decrease the risk of Androgenetic Alopecia in males. AB - It is well established that Androgenetic Alopecia (AGA) occurs in genetically predisposed individuals but little is known of its non-genetic risk factors. The aim of the study was to investigate the role of the Mediterranean diet in determining the risk of AGA. A hospital-based case-control study was conducted in the outpatient clinics of the hospital "Istituto Dermopatico dell'Immacolata, Rome, Italy". We included 104 males and 108 controls not affected by AGA. Controls were frequency matched to cases. Information on socio-demographic characteristics, medical history, smoking and diet were collected for all patients. Logistic regression was used to estimate odds ratio and 95% confidence intervals. After controlling for age, education, body mass index and family history of AGA, protective effects for AGA were found for high consumption (>= 3 times weekly) of raw vegetables (OR 0.43; 95% CI 0.21-0.89) and high consumption of fresh herbs (3 or more regularly) (OR 0.44; 95% CI 0.22-0.87). We suggest that some foods of the Mediterranean diet, say fresh herbs and salad, may reduce the risk of AGA onset. PMID- 29181578 TI - Practical recommendations for fertility preservation in women by the FertiPROTEKT network. Part II: fertility preservation techniques. AB - PURPOSE: In addition to guidelines focusing on scientific evidence, practical recommendations on fertility preservation are also needed. METHODS: A selective literature search was performed based on the clinical and scientific experience of the authors. This article (Part II) focuses on fertility preservation techniques. Part I, also published in this journal, provides information on disease prognosis, disease-specific therapy, and risks for loss of fertility. RESULTS: Ovarian stimulation including double stimulation and freezing of oocytes is the best-established therapy providing live birth chances in women < 35 years with high ovarian reserve of around 30-40%. Ovarian tissue freezing is especially useful in young women with good ovarian, if spontaneous conception is favoured and if < 1 week until chemotherapy is provided. Data on success rates are still limited, but this further evolving technique will possibly reach similar success rates as ovarian stimulation. GnRH agonists seem to reduce the risk of premature ovarian failure up to 50%; however, the effect is possibly not long-lasting. Ovarian transposition can easily be combined with freezing of ovarian tissue and is the preferred technique before pelvic radiotherapy. Other techniques, such as in vitro maturation, are limited to women with high ovarian reserve and remain less effective. In addition, procedures such as in vitro growth of follicles, etc. are still experimental. CONCLUSIONS: Fertility preservation in women provides realistic chances of becoming pregnant. The choice of technique needs to be based on the time required, the woman's age, its risks and efficacy, and the individual preference of the patient. PMID- 29181581 TI - Evaluation of femoral head viability via bone scintigraphy in the postoperative pediatric patient. AB - BACKGROUND: Evaluating postoperative patients with hardware is challenging following surgical intervention for hip maladies such as femoral neck fractures and slipped capital femoral epiphysis (SCFE). These children are at increased risk of developing avascular necrosis, and imaging may be requested to confirm or exclude this diagnosis. Children with Legg-Calve-Perthes disease can be monitored for restoration of blood flow to the capital femoral epiphysis to guide management and help with prognosis. Although MRI is sensitive for detecting early avascular necrosis, the presence of hardware degrades image quality. OBJECTIVE: This report examines the utility of bone scans for evaluating femoral head perfusion in children who have undergone surgery for femoral neck fractures, SCFE or Legg-Calve-Perthes disease. MATERIALS AND METHODS: A retrospective review of 20 patients (22 scans) after fixation for femoral neck fracture, SCFE or Legg Calve-Perthes disease from 2012 to 2015 was performed. The bone scan findings were correlated with the intraoperative findings or clinical follow-up. RESULTS: Twenty-one of the 22 (95%) bone scans in 19 of the 20 (95%) patients demonstrated findings consistent with clinical outcomes and/or the intraoperative appearance of the femoral head. Four of 20 patients (20%) had bone scan features of avascular necrosis, defined as "absent" or "moderately diminished" femoral head activity, which were confirmed intraoperatively and resulted in poor outcomes. CONCLUSION: Radionuclide imaging of hips in the postoperative setting is a valuable modality for assessing the risk of avascular necrosis, a complication of femoral neck fractures and SCFE and for evaluating the restoration of flow to the capital femoral epiphyses of children with Legg-Calve-Perthes disease. PMID- 29181580 TI - Ionizing radiation from computed tomography versus anesthesia for magnetic resonance imaging in infants and children: patient safety considerations. AB - In the context of health care, risk assessment is the identification, evaluation and estimation of risk related to a particular clinical situation or intervention compared to accepted medical practice standards. The goal of risk assessment is to determine an acceptable level of risk for a given clinical treatment or intervention in association with the provided clinical circumstances for a patient or group of patients. In spite of the inherent challenges related to risk assessment in pediatric cross-sectional imaging, the potential risks of ionizing radiation and sedation/anesthesia in the pediatric population are thought to be quite small. Nevertheless both issues continue to be topics of discussion concerning risk and generate significant anxiety and concern for patients, parents and practicing pediatricians. Recent advances in CT technology allow for more rapid imaging with substantially lower radiation exposures, obviating the need for anesthesia for many indications and potentially mitigating concerns related to radiation exposure. In this review, we compare and contrast the potential risks of CT without anesthesia against the potential risks of MRI with anesthesia, and discuss the implications of this analysis on exam selection, providing specific examples related to neuroblastoma surveillance imaging. PMID- 29181582 TI - Contrast-enhanced voiding urosonography (ceVUS) with the intravesical administration of the ultrasound contrast agent OptisonTM for vesicoureteral reflux detection in children: a prospective clinical trial. AB - BACKGROUND: Contrast-enhanced voiding urosonography (ceVUS) is widely used outside the United States to diagnose vesicoureteral reflux (VUR) in children and is highly sensitive while avoiding exposure to ionizing radiation. At the onset of this study, two ultrasound (US) contrast agents were available in the United States. Pediatric safety data for intravenous administration was published for one, OptisonTM. OBJECTIVE: This study aimed to evaluate the diagnostic performance and safety of ceVUS using OptisonTM and compare its diagnostic efficacy with voiding cystourethrogram (VCUG) for VUR detection and grading in children. MATERIALS AND METHODS: The United States Food and Drug Administration and institutional Investigational New Drug authorizations were obtained to conduct a prospective comparative study of ceVUS with OptisonTM and VCUG. CeVUS was performed with intravesical administration of 0.2% OptisonTM/normal saline solution. A standard VCUG followed. Safety assessment included physical examination, and heart rate, pulse oximetry and adverse reactions monitoring before, during and immediately after the examinations. A follow-up questionnaire was completed by telephone 48-h after the studies. RESULTS: Sixty-two pelviureteric units were studied in 30 patients with a mean age of 3.5 years (range: 0.1-17 years) including 21 girls and 9 boys. No severe adverse events occurred. All patients had normal heart rate and blood oxygenation saturation prior to, during and after the studies. At the 48-h follow-up, one patient (3.3%) reported transient dysuria. Taking the VCUG as the reference standard, ceVUS had a sensitivity of 91.7% (95%; confidence interval [CI]: 61.5%-99.8%) and specificity of 98% (95%; CI: 89.4%-99.9%). The concordance between ceVUS and VCUG for VUR detection and grading was 84.3% and 81.8%, respectively. VUR grades were discrepant in 4/11 refluxing pelviureteric units, with VCUG upgrading VUR in 2. CONCLUSION: Detection of VUR with OptisonTM ceVUS was comparable to VCUG without exposure to ionizing radiation. CeVUS with OptisonTM is a well-tolerated diagnostic procedure with a favorable safety profile. PMID- 29181583 TI - Individual differences in emotion processing: how similar are diffusion model parameters across tasks? AB - The goal of this study was to replicate findings of diffusion model parameters capturing emotion effects in a lexical decision task and investigating whether these findings extend to other tasks of implicit emotion processing. Additionally, we were interested in the stability of diffusion model parameters across emotional stimuli and tasks for individual subjects. Responses to words in a lexical decision task were compared with responses to faces in a gender categorization task for stimuli of the emotion categories: happy, neutral and fear. Main effects of emotion as well as stability of emerging response style patterns as evident in diffusion model parameters across these tasks were analyzed. Based on earlier findings, drift rates were assumed to be more similar in response to stimuli of the same emotion category compared to stimuli of a different emotion category. Results showed that emotion effects of the tasks differed with a processing advantage for happy followed by neutral and fear related words in the lexical decision task and a processing advantage for neutral followed by happy and fearful faces in the gender categorization task. Both emotion effects were captured in estimated drift rate parameters-and in case of the lexical decision task also in the non-decision time parameters. A principal component analysis showed that contrary to our hypothesis drift rates were more similar within a specific task context than within a specific emotion category. Individual response patterns of subjects across tasks were evident in significant correlations regarding diffusion model parameters including response styles, non decision times and information accumulation. PMID- 29181584 TI - Testing a potential alternative to traditional identification procedures: Reaction time-based concealed information test does not work for lineups with cooperative witnesses. AB - Direct eyewitness identification is widely used, but prone to error. We tested the validity of indirect eyewitness identification decisions using the reaction time-based concealed information test (CIT) for assessing cooperative eyewitnesses' face memory as an alternative to traditional lineup procedures. In a series of five experiments, a total of 401 mock eyewitnesses watched one of 11 different stimulus events that depicted a breach of law. Eyewitness identifications in the CIT were derived from longer reaction times as compared to well-matched foil faces not encountered before. Across the five experiments, the weighted mean effect size d was 0.14 (95% CI 0.08-0.19). The reaction time-based CIT seems unsuited for testing cooperative eyewitnesses' memory for faces. The careful matching of the faces required for a fair lineup or the lack of intent to deceive may have hampered the diagnosticity of the reaction time-based CIT. PMID- 29181585 TI - [Rheumatism and the spine]. PMID- 29181586 TI - [Indications for joint replacement : Total hip arthroplasty]. AB - Total hip arthroplasty (THA) is a very successful and effective orthopedic operation with very good immediate as well as long-term results to alleviate pain and improve health-related quality of life. A THA is indicated in end-stage hip osteoarthritis with a high degree of persistent suffering when conservative treatment has failed and in patients who wish a THA. This statement is generally valid for patients where the medical history, clinical examination and radiographic findings are conclusive, the pressure of suffering and the expectations are realistic. The timing of THA is based on the patient's discomfort. The treatment of these patients should include an interdisciplinary approach and the main goal is to improve the quality of life. Patients will learn to have reasonable expectations and should be well informed about the risks and benefits of THA. Realistic patient expectations seem to be a predictive factor for a good subjective outcome after THA. PMID- 29181587 TI - Diagnostic accuracy of low and high tube voltage coronary CT angiography using an X-ray tube potential-tailored contrast medium injection protocol. AB - OBJECTIVES: To compare the diagnostic accuracy between low-kilovolt peak (kVp) (<= 100) and high-kVp (> 100) third-generation dual-source coronary CT angiography (CCTA) using a kVp-tailored contrast media injection protocol. METHODS: One hundred twenty patients (mean age = 62.6 years, BMI = 29.0 kg/m2) who underwent catheter angiography and CCTA with automated kVp selection were separated into two cohorts (each n = 60, mean kVp = 84 and 117). Contrast media dose was tailored to the kVp level: 70 = 40 ml, 80 = 50 ml, 90 = 60 ml, 100 = 70 ml, 110 = 80 ml, and 120 = 90 ml. Contrast-to-noise ratio (CNR) was measured. Two observers evaluated image quality and the presence of significant coronary stenosis (> 50% luminal narrowing). RESULTS: Diagnostic accuracy (sensitivity/specificity) with <= 100 vs. > 100 kVp CCTA was comparable: per patient = 93.9/92.6% vs. 90.9/92.6%, per vessel = 91.5/97.8% vs. 94.0/96.8%, and per segment = 90.0/96.7% vs. 90.7/95.2% (all P > 0.64). CNR was similar (P > 0.18) in the low-kVp vs. high-kVp group (12.0 vs. 11.1), as ws subjective image quality (P = 0.38). Contrast media requirements were reduced by 38.1% in the low- vs. high-kVp cohort (53.6 vs. 86.6 ml, P < 0.001) and radiation dose by 59.6% (4.3 vs. 10.6 mSv, P < 0.001). CONCLUSIONS: Automated tube voltage selection with a tailored contrast media injection protocol allows CCTA to be performed at <= 100 kVp with substantial dose reductions and equivalent diagnostic accuracy for coronary stenosis detection compared to acquisitions at > 100 kVp. KEY POINTS: * Low-kVp coronary CT angiography (CCTA) enables reduced contrast and radiation dose. * Diagnostic accuracy is comparable between <= 100 and > 100 kVp CCTA. * Image quality is similar for low- and high-kVp CCTA. * Low-kVp image acquisition is facilitated by automated tube voltage selection. * Tailoring contrast injection protocols to the automatically selected kVp-level is feasible. PMID- 29181588 TI - High doses of folic acid in the periconceptional period and risk of low weight for gestational age at birth in a population based cohort study. AB - PURPOSE: We investigated the association between maternal use of folic acid (FA) during pregnancy and child anthropometric measures at birth. METHODS: We included 2302 mother-child pairs from a population-based birth cohort in Spain (INMA Project). FA dosages at first and third trimester of pregnancy were assessed using a specific battery questionnaire and were categorized in non-user, < 1000, 1000-4999, and >= 5000 ug/day. Anthropometric measures at birth (weight in grams, length and head circumference in centimetres) were obtained from medical records. Small for gestational age according to weight (SGA-w), length (SGA-l) and head circumference (SGA-hc) were defined using the 10th percentile based on Spanish standardized growth reference charts. Multiple linear and logistic regression analyses were used to explore the association between FA dosages in different stages of pregnancy and child anthropometric measures at birth. RESULTS: In the multiple linear regression analysis, we found a tendency for a negative association between the use of high dosages of FA (>= 5000 ug/day) in the periconceptional period of pregnancy and weight at birth compared to mothers who were non-users of FA (beta = - 73.83; 95% CI - 151.71, 4.06). In the multiple logistic regression, a greater risk of SGA-w was also evident among children whose mothers took FA dosages of 1000-4999 (OR = 2.21; 95% CI 1.17, 4.19) and of >= 5000 ug/day (OR = 2.32; 95% CI 1.06, 5.08) compared to mothers non-users of FA in the periconceptional period of pregnancy. CONCLUSION: Our findings suggest that a high dosage of FA (>= 1000 ug/day) may be associated with an increased risk of SGA-w at birth. PMID- 29181589 TI - Disentangling brain activity related to the processing of emotional visual information and emotional arousal. AB - Processing of emotional visual information engages cognitive functions and induces arousal. We aimed to examine the modulatory role of emotional valence on brain activations linked to the processing of visual information and those linked to arousal. Participants were scanned and their pupil size was measured while viewing negative and neutral images. The visual noise was added to the images in various proportions to parametrically manipulate the amount of visual information. Pupil size was used as an index of physiological arousal. We show that arousal induced by the negative images, as compared to the neutral ones, is primarily related to greater amygdala activity while increasing visibility of negative content to enhanced activity in the lateral occipital complex (LOC). We argue that more intense visual processing of negative scenes can occur irrespective of the level of arousal. It may suggest that higher areas of the visual stream are fine-tuned to process emotionally relevant objects. Both arousal and processing of emotional visual information modulated activity within the ventromedial prefrontal cortex (vmPFC). Overlapping activations within the vmPFC may reflect the integration of these aspects of emotional processing. Additionally, we show that emotionally-evoked pupil dilations are related to activations in the amygdala, vmPFC, and LOC.

PMID- 29181591 TI - Post-zygotic genomic changes in glutamate and dopamine pathway genes may explain discordance of monozygotic twins for schizophrenia. AB - BACKGROUND: Monozygotic twins are valuable in assessing the genetic vs environmental contribution to diseases. In the era of complete genome sequences, they allow identification of mutational mechanisms and specific genes and pathways that offer predisposition to the development of complex diseases including schizophrenia. METHODS: We sequenced the complete genomes of two pairs of monozygotic twins discordant for schizophrenia (MZD), including one representing a family tetrad. The family specific complete sequences have allowed identification of post zygotic mutations between MZD genomes. It allows identification of affected genes including relevant network and pathways that may account for the diseased state in pair specific patient. RESULTS: We found multiple twin specific sequence differences between co-twins that included small nucleotides [single nucleotide variants (SNV), small indels and block substitutions], copy number variations (CNVs) and structural variations. The genes affected by these changes belonged to a number of canonical pathways, the most prominent ones are implicated in schizophrenia and related disorders. Although these changes were found in both twins, they were more frequent in the affected twin in both pairs. Two specific pathway defects, glutamate receptor signaling and dopamine feedback in cAMP signaling pathways, were uniquely affected in the two patients representing two unrelated families. CONCLUSIONS: We have identified genome-wide post zygotic mutations in two MZD pairs affected with schizophrenia. It has allowed us to use the threshold model and propose the most likely cause of this disease in the two patients studied. The results support the proposition that each schizophrenia patient may be unique and heterogeneous somatic de novo events may contribute to schizophrenia threshold and discordance of the disease in monozygotic twins. PMID- 29181592 TI - Selection and Qualification of Simplified QSP Models When Using Model Order Reduction Techniques. AB - Quantitative systems pharmacology (QSP) models are increasingly used in drug development to provide a deep understanding of the mechanism of action of drugs and to identify appropriate disease targets. Such models are, however, not suitable for estimation purposes due to their high dimensionality. Based on any desired and specific input-output relationship, the system may be reduced to a model with fewer states and parameters. However, any simplification process will be a trade-off between model performance and complexity. In this study, we develop a weighted composite criterion which brings together the opposing indices of performance and dimensionality. The weighting factor can be determined by qualification of the simplified model based on a visual predictive check (VPC) using the precision of each parameter. The weighted criterion and model qualification techniques were illustrated with three examples: a simple compartmental pharmacokinetic model, a physiologically based pharmacokinetic (PBPK) example, and a semimechanistic model for bone mineral density. When considering the PBPK example, this automated search identified the same reduced model which had been detected in a previous report, as well as a simpler model which had not been previously identified. The simpler bone mineral density model provided an adequate description of the response even after 1 year from the initiation of treatment. The proposed criterion together with a VPC provides a natural way for model order reduction that can be fully automated and applied to multiscale models. PMID- 29181593 TI - Real Patient and its Virtual Twin: Application of Quantitative Systems Toxicology Modelling in the Cardiac Safety Assessment of Citalopram. AB - A quantitative systems toxicology (QST) model for citalopram was established to simulate, in silico, a 'virtual twin' of a real patient to predict the occurrence of cardiotoxic events previously reported in patients under various clinical conditions. The QST model considers the effects of citalopram and its most notable electrophysiologically active primary (desmethylcitalopram) and secondary (didesmethylcitalopram) metabolites, on cardiac electrophysiology. The in vitro cardiac ion channel current inhibition data was coupled with the biophysically detailed model of human cardiac electrophysiology to investigate the impact of (i) the inhibition of multiple ion currents (IKr, IKs, ICaL); (ii) the inclusion of metabolites in the QST model; and (iii) unbound or total plasma as the operating drug concentration, in predicting clinically observed QT prolongation. The inclusion of multiple ion channel current inhibition and metabolites in the simulation with unbound plasma citalopram concentration provided the lowest prediction error. The predictive performance of the model was verified with three additional therapeutic and supra-therapeutic drug exposure clinical cases. The results indicate that considering only the hERG ion channel inhibition of only the parent drug is potentially misleading, and the inclusion of active metabolite data and the influence of other ion channel currents should be considered to improve the prediction of potential cardiac toxicity. Mechanistic modelling can help bridge the gaps existing in the quantitative translation from preclinical cardiac safety assessment to clinical toxicology. Moreover, this study shows that the QST models, in combination with appropriate drug and systems parameters, can pave the way towards personalised safety assessment. PMID- 29181594 TI - Determination of lesinurad in rat plasma by a UHPLC-MS/MS assay. AB - Lesinurad is an oral inhibitor of urate-anion exchanger transporter 1 and has been approved by the US Food and Drug Administration for combination therapy with a xanthine oxidase inhibitor for the treatment of hyperuricemia associated with refractory gout. In the present study, a sensitive and specific ultra high performance liquid chromatography with tandem mass spectrometry assay was established and verified for the determination of lesinurad in rat plasma and was described in details for the first time. Chromatographic separation of lesinurad and diazepam (internal standard, IS) was performed on a Rapid Resolution HT C18 column (3.0 * 100 mm, 1.8 um) using methanol-water (70:30, v/v) as the mobile phase at a flow rate of 0.3 mL/min. Lesinurad and IS were extracted from plasma by liquid-liquid extraction using ethyl acetate. The mass spectrometric detection was carried out using an electrospray ionization source in positive mode. Multiple reaction monitoring was used for quantification of the precursor to product ion at m/z 405.6 -> 220.9 for lesinurad and m/z 285.1 -> 192.8 for IS. The assay was well validated for selectivity, accuracy, precision, recovery, linearity, matrix effects, and stability. The verified method was applied to obtain the pharmacokinetic parameters and concentration-time profiles for lesinurad after oral/intravenous administration in rats. The study might provide an important reference and a necessary complement for the qualitative and quantitative evaluation of lesinurad. PMID- 29181595 TI - Integration of Waste Valorization for Sustainable Production of Chemicals and Materials via Algal Cultivation. AB - Managing waste is an increasing problem globally. Microalgae have the potential to help remove contaminants from a range of waste streams and convert them into useful biomass. This article presents a critical review of recent technological developments in the production of chemicals and other materials from microalgae grown using different types of waste. A range of novel approaches are examined for efficiently capturing CO2 in flue gas via photosynthetic microalgal cultivation. Strategies for using microalgae to assimilate nitrogen, organic carbon, phosphorus, and metal ions from wastewater are considered in relation to modes of production. Generally, more economical open cultivation systems such as raceway ponds are better suited for waste conversion than more expensive closed photobioreactor systems, which might have use for higher-value products. The effect of cultivation methods and the properties of the waste streams on the composition the microalgal biomass is discussed relative to its utilization. Possibilities include the production of biodiesel via lipid extraction, biocrude from hydrothermal liquefaction, and bioethanol or biogas from microbial conversion. Microalgal biomass produced from wastes may also find use in higher value applications including protein feeds or for the production of bioactive compounds such as astaxanthin or omega-3 fatty acids. However, for some waste streams, further consideration of how to manage potential microbial and chemical contaminants is needed for food or health applications. The use of microalgae for waste valorization holds promise. Widespread implementation of the available technologies will likely follow from further improvements to reduce costs, as well as the increasing pressure to effectively manage waste. PMID- 29181597 TI - From lighthouse to hothouse: hospital hygiene, antibiotics and the evolution of infectious disease, 1950-1990. AB - Upon entering clinical medicine in the 1940s, antibiotic therapy seemed to complete a transformation of hospitals that originated in the late nineteenth century. Former death sinks had become harbingers of therapeutic progress. Yet this triumph was short-lived. The arrival of pathologies caused by resistant bacteria, and of nosocomial infections whose spread was helped by antibiotic therapies, seemed to be intimately related to modern anti-infective therapy. The place where such problems culminated were hospitals, which increasingly appeared as dangerous environments where attempts to combat infectious diseases had instead created hothouses of disease evolution. This paper will focus on one aspect of that history. It caused clinical medicine and hospital hygiene in particular to pay attention to a dimension of infectious disease it had previously paid little attention to thus far: The evolution of infectious disease previously a matter of mostly theoretical interest-came to be useful in explaining many phenomena observed. This did not turn hospital hygienists into geneticists, though it did give them an awareness that the evolution of infectious disease in a broad sense was something that did matter to them. The paper advances its argument by looking at three phases: The growing awareness of the hospital as a dangerous environment in the 1950s, comprehensive attempts at improving antibiotic therapy and hospital hygiene that followed from the 1960s and lastly the framing of such challenges as risk factors from the 1970s. In conclusion, I will argue that hospital hygiene, being inspired in particular by epidemiology and risk factor analysis, discussed its own specific version of disease emergence and therefore contributed to the 1980s debates around such topics. Being loosely connected to more specialized studies, it consisted of a re interpretation of infectious disease centred around the temporality of such phenomena as they were encountered in day-to-day dealings of clinical wards. PMID- 29181596 TI - Recent Developments in Single-Walled Carbon Nanotube Thin Films Fabricated by Dry Floating Catalyst Chemical Vapor Deposition. AB - Transparent conducting films (TCFs) are critical components of many optoelectronic devices that pervade modern technology. Due to their excellent optoelectronic properties and flexibility, single-walled carbon nanotube (SWNT) films are regarded as an important alternative to doped metal oxides or brittle and expensive ceramic materials. Compared with liquid-phase processing, the dry floating catalyst chemical vapor deposition (FCCVD) method without dispersion of carbon nanotubes (CNTs) in solution is more direct and simpler. By overcoming the tradeoff between CNT length and solubility during film fabrication, the dry FCCVD method enables production of films that contain longer CNTs and offer excellent optoelectronic properties. This review focuses on fabrication of SWNT films using the dry FCCVD method, covering SWNT synthesis, thin-film fabrication and performance regulation, the morphology of SWNTs and bundles, transparency and conductivity characteristics, random bundle films, patterned films, individual CNT networks, and various applications, especially as TCFs in touch displays. Films based on SWNTs produced by the dry FCCVD method are already commercially available for application in touch display devices. Further research on the dry FCCVD method could advance development of not only industrial applications of CNTs but also the fundamental science of related nanostructured materials and nanodevices. PMID- 29181598 TI - History as a biomedical matter: recent reassessments of the first cases of Alzheimer's disease. AB - This paper examines medical scientists' accounts of their rediscoveries and reassessments of old materials. It looks at how historical patient files and brain samples of the first cases of Alzheimer's disease became reused as scientific objects of inquiry in the 1990s, when a genetic neuropathologist from Munich and a psychiatrist from Frankfurt lead searches for left-overs of Alzheimer's 'founder cases' from the 1900s. How and why did these researchers use historical methods, materials and narratives, and why did the biomedical community cherish their findings as valuable scientific facts about Alzheimer's disease? The paper approaches these questions by analysing how researchers conceptualised 'history' while backtracking and reassessing clinical and histological materials from the past. It elucidates six ways of conceptualising history as a biomedical matter: (1) scientific assessments of the past, i.e. natural scientific understandings of 'historical facts'; (2) history in biomedicine, e.g. uses of old histological collections in present day brain banks; (3) provenance research, e.g. applying historical methods to ensure the authenticity of brain samples; (4) technical biomedical history, e.g. reproducing original staining techniques to identify how old histological slides were made; (5) founding traditions, i.e. references to historical objects and persons within founding stories of scientific communities; and (6) priority debates, e.g. evaluating the role particular persons played in the discovery of a disease such as Alzheimer's. Against this background, the paper concludes with how the various ways of using and understanding 'history' were put forward to re-present historic cases as 'proto-types' for studying Alzheimer's disease in the present. PMID- 29181599 TI - Bioconversion of farnesol and 1,4-dihydroxy-2-naphthoate to menaquinone by an immobilized whole-cell biocatalyst using engineered Elizabethkingia meningoseptica. AB - Menaquinone (MK) has important applications in the pharmaceutical and food industries. To increase the production rate (QP) of MK-4, we developed a straightforward biotransformation method for MK-4 synthesis directly from its precursors 1,4-dihydroxy-2-naphthoate (DHNA) and farnesol using whole cells of genetically engineered Elizabethkingia meningoseptica. Results showed that MK-4 can be produced directly from farnesol and DHNA using both free and immobilized FM-D198 cells. MK-4 yield peaked at 29.85 +/- 0.36 mg/L in the organic phase and 24.08 +/- 0.33 mg/g DCW after 12 h of bioconversion using free cells in a two phase conversion system. MK-4 yield reached 26.34 +/- 1.35 mg/L and 17.44 +/- 1.05 mg/g DCW after 8 h using immobilized cells. Although this yield was lower than that using free cells, immobilized cells can be re-used for MK-4 production via repeated-batch culture. After ten batch cultures, efficient MK-4 production was maintained at a yield of more than 20 mg/L. After optimizing the catalysis system, the MK-4 yield reached 26.91 +/- 1.27 mg/L using the immobilized cells and had molar conversion rates of 58.56 and 76.90% for DHNA and farnesol, respectively. PMID- 29181600 TI - Strategies for improving production performance of probiotic Pediococcus acidilactici viable cell by overcoming lactic acid inhibition. AB - Lactic acid bacteria are industrially important microorganisms recognized for fermentative ability mostly in their probiotic benefits as well as lactic acid production for various applications. Fermentation conditions such as concentration of initial glucose in the culture, concentration of lactic acid accumulated in the culture, types of pH control strategy, types of aeration mode and different agitation speed had influenced the cultivation performance of batch fermentation of Pediococcus acidilactici. The maximum viable cell concentration obtained in constant fed-batch fermentation at a feeding rate of 0.015 L/h was 6.1 times higher with 1.6 times reduction in lactic acid accumulation compared to batch fermentation. Anion exchange resin, IRA 67 was found to have the highest selectivity towards lactic acid compared to other components studied. Fed-batch fermentation of P. acidilactici coupled with lactic acid removal system using IRA 67 resin showed 55.5 and 9.1 times of improvement in maximum viable cell concentration compared to fermentation without resin for batch and fed-batch mode respectively. The improvement of the P. acidilactici growth in the constant fed batch fermentation indicated the use of minimal and simple process control equipment is an effective approach for reducing by-product inhibition. Further improvement in the cultivation performance of P. acidilactici in fed-bath fermentation with in situ addition of anion-exchange resin significantly helped to enhance the growth of P. acidilactici by reducing the inhibitory effect of lactic acid and thus increasing probiotic production. PMID- 29181601 TI - Acute Flaccid Myelitis: Etiologic Challenges, Diagnostic and Management Considerations. AB - PURPOSE OF REVIEW: Purpose of review Acute flaccid myelitis is a polio-like illness defined by the acute onset of flaccid paralysis in the setting spinal MRI demonstrating a longitudinal lesion in the gray matter of the cord. This paper aims to review the current state of knowledge and key clinical points for the diagnosis and management of acute flaccid myelitis. RECENT FINDINGS: Recent findings There were clusters of AFM noted in California and Colorado in 2014, with additional cases across the USA that year, and another spike in cases in 2016. Patients have been managed with classic treatments for transverse myelitis, but in general without benefit, although some colleagues have noted anecdotal improvement in individual patients. Our current practice at the Children's Hospital of Philadelphia is to initiate therapy with intravenous immunoglobulin (IVIG) upon recognition of acute flaccid myelitis in hopes of boosting humoral immunity, and to provide an emphasis on rehabilitation services, including physical and occupational therapy. There is some data that suggests a connection to the virus enterovirus D68 (EV D68), but there has been no definitive link. Publications regarding longer-term outcomes in these patients are early in development and, thus far, only provide data for 6 to 12 months from onset. Summary AFM is a serious illness with long-term consequences, and we have much to learn. Key areas in need of further investigation involve etiology, host susceptibilities, treatment options, and long-term outcome. Individual clinicians can assist in these efforts by the prompt reporting of cases of AFM to the US Centers for Disease Control and Prevention. PMID- 29181602 TI - Long Parallel Stent Grafts for the Treatment of Complex Aortic Aneurysms. AB - PURPOSE: To describe our experience with the chimney technique in endovascular aneurysm repair (ch-EVAR) using long parallel grafts (PGs) of 100 mm or more for the treatment of complex aortic aneurysms. MATERIALS AND METHODS: From 2009 to 2016, data were prospectively collected for patients who underwent ch-EVAR using long PGs. Data included patient demographics and aortic anatomy, technical success, patency and reintervention rate. RESULTS: A total of 29 long PGs were placed in 18 patients (males 16, average age 71 years). Nine (50%) suffered from thoracoabdominal aortic aneurysms, 4 (22%) from juxtarenal aortic aneurysms and 3 (17%) from suprarenal aortic aneurysms and 2 (11%) were treated for abdominal aortic aneurysms that required revascularization of a pelvic kidney. Twenty (70%) of the PGs were 100 mm in length, and 9 (30%) were 150 mm. Long PGs were successfully placed in 16 (89%) patients. Two patients (11%) expired in the perioperative period. Mean period of follow-up was 12 months (range 1-43 months). Sac size decreased in size or remained unchanged in 13 patients (72%). Three patients with sac enlargement underwent successful endovascular treatment the type 1A gutter endoleaks. None required reintervention of the PGs. Three patients expired, none from aneurysm-related deaths. CONCLUSION: The use of long PGs is a feasible technique and provides a durable repair of complex aortic aneurysms in midterm follow-up. Despite the length of the PGs, gutter endoleaks are encountered only in a minority of the cases and can be treated minimally invasive techniques.

PMID- 29181605 TI - Symptomatic Heart Failure After Transjugular Intrahepatic Portosystemic Shunt Placement: Incidence, Outcomes, and Predictors. AB - PURPOSE: To assess the incidence of symptomatic heart failure (SHF) occurring after transjugular intrahepatic portosystemic shunt (TIPS) placement, identify potential predictors of SHF, and evaluate clinical presentation and outcomes in cases of post-TIPS SHF. MATERIALS AND METHODS: A prospectively maintained TIPS database was used to identify patients who underwent new TIPS placements at a large urban tertiary care center between 1995 and 2014. SHF was defined as otherwise unexplained new-onset dyspnea, hypoxemia, radiologic pulmonary edema, an increased need for diuretics, or need for intubation within 7 days after TIPS placement. Cases of deaths occurring within 7 days due to septic shock, continuing gastrointestinal bleed, or multi-organ failure were excluded. A control group consisting of a random sample of 40 patients from the same TIPS database was created. Uni-variable analysis was performed to assess differences between patients with and without post-TIPS SHF. RESULTS: Of the 934 TIPS procedures performed during the study period, 883 met the inclusion criteria. Eight (0.9%) patients developed SHF, usually manifested by hypoxemia (50%) or dyspnea (25%) within 48 h. Patients with SHF had higher pre-TIPS right atrial (p = 0.03) and portal vein (p = 0.01) pressures, higher albumin (p = 0.02), and higher prothrombin time (p = 0.02). CONCLUSION: Post-TIPS SHF is rare. Higher pre TIPS right atrial and portal vein pressures are likely to predispose patients to this complication. Close monitoring may be warranted in these patients. In our eight patients, post-TIPS SHF did not result in poor outcomes. PMID- 29181606 TI - Trace Element Concentrations in Tree Leaves and Lichen Collected Along a Metal Pollution Gradient Near Olkusz (Southern Poland). AB - The aim of the study was to assess the metal pollution in the vicinity of the Bukowno smelter near Olkusz in southern Poland. Birch and oak leaves, pine needles and a lichen Hypogymnia physodes, overgrowing pine bark were collected at stands at different distances from the smelter and analysed for cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn) content. Concentrations of metals in the lichen were usually higher than in the tree leaves/needles and decreased with distance from the smelter, apart from the Cu content. The strongest correlation was noticed between Cd and Pb concentrations, which indicates a common pollution source (the smelter). Our results show that birch leaves can be potentially useful as a bioindicator of Zn air pollution since this species was shown to accumulate high amounts of zinc, related to environmental pollution with that metal, in their leaves. PMID- 29181607 TI - Cryptosporidium spp. Contamination in Perna perna Mussels Destined for Human Consumption in Southeastern Rio de Janeiro, Brazil. AB - Cryptosporidium spp. has been recognized as an important pathogen. As bivalve mollusks are noted as potential sources of several pathogens due to their consumption as foodstuffs, the aim of this study was to investigate the occurrence of Cryptosporidium spp. oocysts in Perna perna mussels and in seawater samples from a mussel farm in Southeastern Brazil, where mussels are grown directly in the sea, attached to ropes. Oocysts were observed by microscopy and confirmed by an enzyme-linked immunosorbent assay. Oocysts were present in mussel gills and GI tracts, as well as in the seawater. Of the 100 females, 10% and 11% showed contaminated GI tracts and gills, respectively, while this rate was lower in males, at 5% and 8.9%. Oocysts were present in higher amounts in the GI tract compared to gills and water. Contamination of the study area is apparent, leading to public health risks. More in-depth studies are needed, including molecular investigations, to identify Cryptosporidium species in mussels, as well as the implementation of monitoring actions in animals destined for human consumption. PMID- 29181609 TI - A New Class III Antiarrhythmic Drug Niferidil Prolongs Action Potentials in Guinea Pig Atrial Myocardium via Inhibition of Rapid Delayed Rectifier. AB - PURPOSE: A new class III antiarrhythmic drug niferidil (RG-2) has been introduced as a highly effective therapy for cases of persistent atrial fibrillation, but ionic mechanisms of its action are poorly understood. In the present study, the effects of niferidil on action potential (AP) waveform and potassium currents responsible for AP repolarization were investigated in guinea pig atrial myocardium. METHODS: APs were recorded with sharp glass microelectrodes in multicellular atrial preparations. Whole-cell patch-clamp technique was used to measure K+ currents in isolated myocytes. RESULTS: In multicellular atrial preparations, 10-8 M niferidil effectively prolonged APs by 15.2 +/- 2.8% at 90% repolarization level. However, even the highest tested concentrations, 10-6 M and 10-5 M failed to prolong APs more than 32.5% of control duration. The estimated concentration of niferedil for half-maximal AP prolongation was 1.13 * 10-8 M. Among the potassium currents responsible for AP repolarization phase, I K1 was found to be almost insensitive to niferidil. However, another inward rectifier, I KACh, was effectively suppressed by micromolar concentrations of niferidil with IC50 = 9.2 * 10-6 M. I KATP was much less sensitive to the drug with IC50 = 2.26 * 10-4 M. The slow component of delayed rectifier, I Ks, also demonstrated low sensitivity to niferidil-the highest used concentration, 10-4 M, decreased peak I Ks density to 46.2 +/- 5.5% of control. Unlike I Ks, the rapid component of delayed rectifier, I Kr, appeared to be extremely sensitive to niferidil. The IC50 was 1.26 * 10-9 M. I Kr measured in ventricular myocytes was found to be less sensitive to niferidil with IC50 = 3.82 * 10-8 M. CONCLUSIONS: Niferidil prolongs APs in guinea pig atrial myocardium via inhibition of I Kr. PMID- 29181608 TI - Immunolocalization patterns of cytokeratins during salivary acinar cell development in mice. AB - Embryonic development of the mouse salivary glands begins with epithelial thickening and continues with sequential changes from the pre-bud to terminal bud stages. After birth, morphogenesis proceeds, and the glands develop into a highly branched epithelial structure that terminates with saliva-producing acinar cells at the adult stage. Acinar cells derived from the epithelium are differentiated into serous, mucous, and seromucous types. During differentiation, cytokeratins, intermediate filaments found in most epithelial cells, play vital roles. Although the localization patterns and developmental roles of cytokeratins in different epithelial organs, including the mammary glands, circumvallate papilla, and sweat glands, have been well studied, their stage-specific localization and morphogenetic roles during salivary gland development have yet to be elucidated. Therefore, the aim of this study was to determine the stage and acinar cell type specific localization pattern of cytokeratins 4, 5, 7, 8, 13, 14, 18, and 19 in the major salivary glands (submandibular, sublingual, and parotid glands) of the mouse at the E15.5, PN0, PN10, and adult stages. In addition, cell physiology, including cell proliferation, was examined during development via immunostaining for Ki67 to understand the cellular mechanisms that govern acinar cell differentiation during salivary gland morphogenesis. The distinct localization patterns of cytokeratins in conjunction with cell physiology will reveal the roles of epithelial cells in salivary gland formation during the differentiation of serous, mucous or seromucous salivary glands. PMID- 29181610 TI - Barriers to Beta-Blocker Use and Up-Titration Among Patients with Heart Failure with Reduced Ejection Fraction. AB - PURPOSE: For patients with heart failure with reduced ejection fraction (HFrEF), guidelines recommend use of beta-blockers with gradual up-titration. However, many patients with HFrEF do not use beta-blockers and up-titration is rare. Our purpose was to identify and rank barriers to beta-blocker use and up-titration from the perspective of primary care physicians. METHODS: We conducted 4 moderated, structured group discussions among 19 primary care physicians using the nominal group technique; 16 participants also completed a survey. Participants generated lists of barriers to beta-blocker use and up-titration among patients with HFrEF. Each participant had six votes with three votes assigned to the item ranked most important, two to the second most important item, and one to the third most important item. Investigators characterized items into themes. The percentage of available votes was calculated for each theme. RESULTS: Fifteen of 16 participating primary care physicians who completed the survey reported that management of beta-blockers was their responsibility. Treatment/side effects, particularly hypotension, were identified as the most important barrier for beta-blocker use (72% of available votes) followed by polypharmacy (11%), healthcare system barriers (10%), and comorbidities (6%). Barriers to up-titration included treatment/side effects (49% of available votes), patient communication/buy-in (21%), polypharmacy (13%), and healthcare system barriers (8%). CONCLUSIONS: Many barriers to guideline concordant use of beta-blockers among patients with HFrEF identified by primary care providers are not readily modifiable. Addressing these barriers may require development, testing, and dissemination of protocols for beta-blocker initiation and up titration that are safe and appropriate in primary care.

AB - Fevers of unknown origin complicate treatment and prevention of infectious diseases and are a global health burden. We examined risk factors of self reported fever-categorized as "malarial" and "nonmalarial"-in households adjacent to national parks across the Ugandan Albertine Rift, a biodiversity and emerging infectious disease hotspot. Statistical models fitted to these data suggest that perceived nonmalarial fevers of unknown origin were associated with more frequent direct contact with wildlife and with increased distance from parks where wildlife habitat is limited to small forest fragments. Perceived malarial fevers were associated with close proximity to parks but were not associated with direct wildlife contact. Self-reported fevers of any kind were not associated with livestock ownership. These results suggest a hypothesis that nonmalarial fevers in this area are associated with wildlife contact, and further investigation of zoonoses from wildlife is warranted. More generally, our findings of land use disease relationships aid in hypothesis development for future research in this social-ecological system where emerging infectious diseases specifically, and rural public health provisioning generally, are important issues.

AB - Despite having normal hearing sensitivity, patients with chronic tinnitus may experience more difficulty recognizing speech in adverse listening conditions as compared to controls. However, the association between the characteristics of tinnitus (severity and loudness) and speech recognition remains unclear. In this study, the Quick Speech-in-Noise test (QuickSIN) was conducted monaurally on 14 patients with bilateral tinnitus and 14 age- and hearing-matched adults to determine the relation between tinnitus characteristics and speech understanding. Further, Tinnitus Handicap Inventory (THI), tinnitus loudness magnitude estimation, and loudness matching were obtained to better characterize the perceptual and psychological aspects of tinnitus. The patients reported low THI scores, with most participants in the slight handicap category. Significant between-group differences in speech-in-noise performance were only found at the 5 dB signal-to-noise ratio (SNR) condition. The tinnitus group performed significantly worse in the left ear than in the right ear, even though bilateral tinnitus percept and symmetrical thresholds were reported in all patients. This between-ear difference is likely influenced by a right-ear advantage for speech sounds, as factors related to testing order and fatigue were ruled out. Additionally, significant correlations found between SNR loss in the left ear and tinnitus loudness matching suggest that perceptual factors related to tinnitus had an effect on speech-in-noise performance, pointing to a possible interaction between peripheral and cognitive factors in chronic tinnitus. Further studies, that take into account both hearing and cognitive abilities of patients, are needed to better parse out the effect of tinnitus in the absence of hearing impairment.

PMID- 29181617 TI - Occult invasion of sternothyroid muscle by differentiated thyroid cancer. AB - PURPOSE: To determine the incidence of occult invasion of sternothyroid by differentiated thyroid cancer (DTC) and identify clinico-pathological features associated with the same. METHODS: Retrospective study of a consecutive series of DTC patients undergoing surgery, with preoperative ultrasound showing no evidence of strap muscle invasion. All had en bloc excision of sternothyroid muscle along with thyroidectomy. Incidence of microscopic invasion of sternothyroid and clinicopathologic features associated with the same, were studied. RESULTS: A total of 76 patients with DTC (2010-2014) were identified, of whom 62 met the inclusion criteria and were included in this study. Of these, 22 (36%) had no extrathyroidal extension (ETE), 30 (48%) had minimal ETE without sternothyroid invasion and 10 (16%) had minimal ETE with microscopic sternothyroid invasion. The mean tumor sizes of the three sub-groups were 1.9, 3.1 and 4.9 cm, respectively, with a significant difference between no ETE and sternothyroid invaded sub-groups (p = 0.03). Out of the 40 cases with minimal ETE, 3 (7.5%) had positive tumor microscopic margin. Retaining sternothyroid in situ would have theoretically increased this proportion to 27.5%. Over a median follow-up of 52 months, 58 (94%) patients remained structurally disease free, with only 1 local recurrence. CONCLUSION: Occult invasion of sternothyroid muscle occurred in 16% of DTC in this series. Excision of the muscle en bloc with thyroidectomy, particularly in larger tumors, may confer benefit in accurately staging the disease, encompassing occult ETE and achieving clear microscopic margins.

AB - PURPOSE: MicroRNA-326 (miR-326), as a member of the microRNA (miRNA) family, which includes endogenous single-stranded, conserved, noncoding small RNAs, has been reported to play important roles in autoimmune diseases such as multiple sclerosis and systemic lupus erythematosus. However, few studies of the role of miR-326 in autoimmune thyroiditis (AIT) have been published. Here, we explored the roles of miR-326 and the involved pathway in iodine-induced AIT. METHODS: NOD.H-2h4 mice, which are a model of human AIT, were randomly divided into a normal water control group and a high-iodine group. Mice in the high-iodine group were administered 0.05% NaI (~1000 times the normal daily iodine intake), and mice in the control group received sterile water. Furthermore, we evaluated small interfering RNA (siRNA) interference in spleen mononuclear cell experiments in vitro. RESULTS: In this study, we found that Th17 cells were significantly increased with a high expression of miR-326 in an iodine-induced thyroiditis NOD.H-2h4 mouse model. In addition, the expression of Ets-1 protein, a negative regulator of Th17 differentiation, was significantly decreased. Intriguingly, our analysis showed that Ets-1 protein expression was negatively correlated with miR 326 levels in AIT mice (r = -0.814, p < 0.01). Our study indicated that miR-326 inhibited Ets-1 protein expression and promoted the differentiation of Th17 cells during the onset and development of AIT. The addition of a miR-326 inhibitor reversed Th17 cell production and Ets-1 protein expression, supporting this hypothesis. CONCLUSIONS: The results of our study suggest that miR-326 may target the Ets-1 protein to contribute to iodide-induced thyroiditis, providing a new theoretical basis for the use of miRNA targeting therapy for the treatment of autoimmune diseases. PMID- 29181620 TI - Consumption of heavy metal contaminated foods and associated risks in Bangladesh. AB - This study investigated the magnitude of heavy metal contamination and determined the carcinogenic as well as non-carcinogenic risks associated with selected food consumption in Bangladesh. Commonly consumed varieties of rice, vegetables, and fish samples were analyzed to measure the concentrations of heavy metals such as cadmium, chromium, lead, arsenic, manganese, nickel, and zinc. These staple food items showed the greatest probabilities of heavy metal contamination in different phases of their production and marketing. Wide variations of metal concentrations were observed. Specifically, estimated daily intakes of arsenic and cadmium exceeded allowable daily intakes in all three food items. Toxicity scores of the metals were evaluated, and a comprehensive risk assessment was conducted to quantify the risks associated with the daily food consumption. Except for cadmium and lead in vegetables, all the contaminants present in each food item posed significant levels of carcinogenic risks up to 2.99 * 10-3 compared to the EPA recommended carcinogenic risk level of 1.0 * 10-6. Cadmium and arsenic intake due to rice consumption also posed unsafe levels of non-carcinogenic risks of 4.587 and 6.648, respectively, compared to the EPA recommended non-carcinogenic risk level of 1.0. Finally, a revised set of permissible limits was proposed for the heavy metals detected in the food items. Those permissible limits would ensure the risks associated with food consumption below the allowable carcinogenic and non-carcinogenic risk levels. Thus, this comprehensive approach would provide guidelines to formulate adequate control measures and regulatory limits of toxic metals in foods produced and marketed in Bangladesh. PMID- 29181621 TI - Monocyte chemoattractant protein-1 as a marker of systemic lupus erythematosus: an observational study. AB - There is a pivotal need for new markers to be tested in every day clinical practice for systemic lupus erythematosus (SLE) and lupus nephritis (LN). The levels of monocyte chemoattractant protein-1 (MCP-1) in the serum and urine of 72 SLE patients (27 with LN and 45 without LN involvement) and 30 healthy individuals were studied to establish their clinical significance. The SLE Disease Activity Index (SLEDAI) was used to establish the disease activity. Urine and serum MCP-1 was determined using the sandwich enzyme immunosorbent assay. Urinary, but not serum MCP-1, positively correlated with proteinuria (r = 0.839; p < 0.001) and negatively correlated with glomerular filtration, evaluated using the modification of diet in renal disease (MDRD) formula (r = - 0.293; p < 0.05), and with C3 complement component in active LN patients (r = - 0.519, p = 0.019). Both serum and urinary MCP-1 demonstrated a positive correlation with SLEDAI (r = 0.318; p < 0.01 and r = 0.431; p < 0.001). We also demonstrated that the levels of serum and urinary MCP-1 were significantly higher in patients with SLE compared to healthy controls, regardless of the disease activity and renal involvement. We recommend MCP-1 measurement in the routine laboratory follow-up of the SLE patients. PMID- 29181622 TI - Neuromuscular fatigue is weakly associated with perception of fatigue and function in patients with rheumatoid arthritis. AB - To assess electromyographic parameters of neuromuscular fatigue in knee extensors and their association with clinical, functional and emotional features in patients with rheumatoid arthritis (RA). Thirty-eight female patients with RA participated. Electromyography parameters (changes in signal amplitude, represented by the root mean square, and frequency content, represented by median frequency-MDF) were assessed during a submaximal (60%) isometric contraction of the knee extensors, sustained for 60 s. Clinical characteristics; the 28-joint Disease Activity Score (DAS-28) in which includes count of swollen joints (out of the 28) and tender joints (out of the 28), the erythrocyte sedimentation rate and global disease activity measured on a visual analogue scale; serum C reactive protein (CRP); information on treatment; the Health Assessment Questionnaire; the Functional Assessment of Chronic Illness Therapy fatigue scale (FACIT-F); the Short Form Health Survey (SF-36) and the International Physical Activity Questionnaire (IPAQ), were also assessed. The mean patient age was 51.0 +/- 8.2 years, mean disease activity score was 11.5 +/- 7.1, and mean CRP level was 8.0 +/- 7.8 mg/dL. There was a moderate correlation between MDF and age (r = 0.5), as well as weak correlations of MDF with FACIT-F (r = 0.3), physical functioning (r = - 0.3) and vitality domains (r = - 0.3) of the SF-36, and IPAQ (r = - 0.3) (p <= 0.05 for all). No association was observed between electromyography measurements and clinical or treatment features. The electromyographic parameter MDF was correlated with perception of fatigue, age, physical functioning and vitality domains of SF-36, and physical activity level in this sample. These results indicate that primary muscle factors should also be considered when managing perceived fatigue in patients with RA. PMID- 29181623 TI - Complete genome sequence of shrimp hemocyte iridescent virus (SHIV) isolated from white leg shrimp, Litopenaeus vannamei. AB - Infection with shrimp hemocyte iridescent virus (SHIV), a new virus of the family Iridoviridae isolated in China, results in a high mortality rate in white leg shrimp (Litopenaeus vannamei). The complete genome sequence of SHIV was determined and analyzed in this study. The genomic DNA was 165,809 bp long with 34.6% G+C content and 170 open reading frames (ORFs). Dotplot analysis showed that the longest repetitive region was 320 bp in length, including 11 repetitions of an 18-bp sequence and 3.1 repetitions of a 39-bp sequence. Two phylogenetic trees were constructed based on 27 or 16 concatenated sequences of proteins encoded by genes that are conserved between SHIV homologous and other iridescent viruses. The results of this study, suggest that SHIV should be considered a member of the proposed new genus "Xiairidovirus". PMID- 29181624 TI - Significant differences in the intra-host genetic diversity of Helicoverpa armigera nucleopolyhedrovirus dnapol after serial in vivo passages in the same insect population. AB - A denaturing gradient gel electrophoresis assay was used to assess the genetic diversity within a region of the DNA polymerase gene (dnapol) in Helicoverpa armigera nucleopolyhedrovirus (HearNPV) populations over serial in vivo passages. There was no evidence of movement towards a consensus dnapol variant composition in the different host larvae after multiple per os passages. The study showed that the HearNPV variant structure after in vivo passages in the same host population is not necessarily convergent, and that it may be reasonable to expect significant differences in intra-host HearNPV genetic diversity after inoculation of larvae with a genotypically-diverse HearNPV inoculum. PMID- 29181625 TI - Development of a high-resolution infrared thermographic imaging method as a diagnostic tool for acute undifferentiated limp in young children. AB - Acute limp is a common presenting condition in the paediatric emergency department. There are a number of causes of acute limp that include traumatic injury, infection and malignancy. These causes in young children are not easily distinguished. In this pilot study, an infrared thermographic imaging technique to diagnose acute undifferentiated limp in young children was developed. Following required ethics approval, 30 children (mean age = 5.2 years, standard deviation = 3.3 years) were recruited. The exposed lower limbs of participants were imaged using a high-resolution thermal camera. Using predefined regions of interest (ROI), any skin surface temperature difference between the healthy and affected legs was statistically analysed, with the aim of identifying limp. In all examined ROIs, the median skin surface temperature for the affected limb was higher than that of the healthy limb. The small sample size recruited for each group, however, meant that the statistical tests of significant difference need to be interpreted in this context. Thermal imaging showed potential in helping with the diagnosis of acute limp in children. Repeating a similar study with a larger sample size will be beneficial to establish reproducibility of the results. Graphical abstract A young child with an acute undifferentiated limp undergoes thermal imaging and the follow on image analysis assists the limp diagnosis. PMID- 29181626 TI - Pure alexia: two cases and a new neuroanatomical classification. AB - Pure alexia without visual or language accompanying deficits (isolated pure alexia), represents an infrequent finding in clinical practice. It has been linked to lesions involving the splenium of the callosal corpus in classical descriptions; however, it has also been reported after occipito-temporal cortex damage in the absence of white matter implication. In this regard, a functional region called the visual word form area has been recently related to the posterior aspect of the occipitotemporal gyrus. We report two new cases of cortical hematomas leading to this rare condition and we discuss the neuroanatomical evolution of this syndrome. Finally, we propose a new classification of pure alexia based on the neuroanatomical location of the lesion, namely: (1) disconnection alexia, after posterior and dorsal lesions involving the splenium of the callosal corpus or the paraventricular white matter, often associated with visual deficits, and (2) cortical alexia, after more anterior and ventral lesions in the occipito-temporal cortex with damage of the visual word form area, that usually manifests as isolated pure alexia. PMID- 29181627 TI - Pompe disease in Austria: clinical, genetic and epidemiological aspects. AB - In this study, we performed a survey of infantile and late-onset Pompe disease (IOPD and LOPD) in Austria. Paediatric and neuromuscular centres were contacted to provide a set of anonymized clinical and genetic data of patients with IOPD and LOPD. The number of patients receiving enzyme replacement therapy (ERT) was obtained from the pharmaceutical company providing alglucosidase alfa. We found 25 patients in 24 families, 4 IOPD and 21 LOPD with a resulting prevalence of 1:350,914. The most frequent clinical manifestation in LOPD was a lower limb girdle phenotype combined with axial weakness. Three patients were clinically pauci- or asymptomatic and were diagnosed because of persistent hyperCKemia. Diagnostic delay in LOPD was 7.4 +/- 9.7 years. The most common mutation was c. 32-13T > G. All IOPD and 17 symptomatic LOPD patients are receiving ERT. Standardized follow-up was only available in six LOPD patients for the 6-min walk test (6minWT) and in ten for the forced vital capacity (FVC). Mean FVC did not decline (before ERT; 63.6 +/- 39.7%; last evaluation during ERT: 61.9 +/- 26.9%; P = 0.5) while there was a trend to decline in the mean distance covered by the 6minWT (before ERT: 373.5 +/- 117.9 m; last evaluation during ERT: 308.5 +/- 120.8 m; P = 0.077). The study shows a lower prevalence of Pompe disease in Austria than in other European countries and corroborates a limb-girdle phenotype with axial weakness as the most common clinical presentation, although asymptomatic hyperCKemia may be the first indication of LOPD. PMID- 29181628 TI - The major contribution of the DNA damage-triggered reactive oxygen species production to cell death: implications for antimicrobial and cancer therapy. AB - Genotoxic agents damage DNA, block DNA replication and provoke cell death. However, there is growing evidence that an important part of their cytotoxicity results from metabolic disturbances induced by treatment. This review article describes how increased production of the reactive oxygen species (ROS) induced by different genotoxic agents contribute to death of prokaryotic and eukaryotic cells. ROS are byproducts of normal cellular functioning. Because ROS are damaging cellular macromolecules, they are constantly eliminated by protective antioxidant mechanisms. However, even a small increase in ROS production may have deleterious consequences because cells possess just enough defensive mechanisms to protect themselves against endogenously produced ROS. Therefore, it may be possible to enhance cytotoxic potential of antimicrobial and anticancer drugs by increasing ROS production or by inhibiting cellular antioxidant systems. PMID- 29181629 TI - Linking neuronal structure to function in rodent hippocampus: a methodological prospective. AB - Since the discovery of place cells, hippocampus-dependent spatial navigation has proven to be an ideal model system for resolving the relationship between neural coding and behavior. Electrical recordings from the hippocampal formation in freely moving animals have revealed a rich repertoire of spatial firing patterns and have enormously advanced our understanding of the neural principles of spatial representation. However, limited progress has been achieved in resolving the underlying cellular mechanisms. This is partially attributable to the inability of standard recording techniques to link neuronal structure to function directly. In this review, we summarize recent efforts aimed at filling this gap. We also highlight the development of methodologies that allow functional measurements from identified neuronal elements in behaving rodents. Recent progress in the dentate gyrus serves as a showcase to reveal the potential of such methodologies and the necessity of resolving structure-function relationships in order to access the cellular mechanisms of hippocampal circuit computations. PMID- 29181630 TI - Detection and complete genome characteristics of Posavirus 1 from pigs in China. AB - Porcine stool-associated RNA virus 1 (Posavirus 1) is a novel member of picornaviruses and first identified from fecal samples of 30-day-old pigs with diarrhea in USA in 2011. To evaluate the existence of Posavirus 1 in swine herds, 118 clinical samples from diarrheal pigs and 31 fecal swabs from healthy pigs were collected and detected by reverse transcription-polymerase chain reaction (RT-PCR) using Posavirus 1-specific primers. Only five fecal samples from diarrheal pigs on two swine farms were positive for Posavirus 1. The complete genome sequences [excluding poly (A) tail] of two representative isolates SDQD-25 and HBTS-11 are determined and consist of 9840 and 9819 nucleotides in length, and encode one putative polyprotein of 3070 and 2952 amino acids, respectively. They share 90.3% homology with each other and 81.3-95.4% homologies with American Posavirus 1 isolates or strains at the nucleotide sequence level. The phylogenetic analysis based on the entire genomes of reference picornavirus strains or isolates showed SDQD-25, HBTS-11 cluster together with American Posavirus 1 isolates or strains, yet are clearly distant from the other picornaviruses. The complete genome sequences of Chinese Posavirus 1 isolates will enrich the information of Posavirus 1 sequence database and further expedite posavirus research on the genetic diversity, epidemiology, and evolution in China. PMID- 29181631 TI - A novel Bi4Ti3O12/Ag3PO4 heterojunction photocatalyst with enhanced photocatalytic performance. AB - In this work, we integrated Ag3PO4 with Bi4Ti3O12 to form Bi4Ti3O12/Ag3PO4 heterojunction nanocomposites by an ion-exchange method. The as-prepared Bi4Ti3O12/Ag3PO4 composites were systematically characterized by means of XRD, SEM, TEM, BET, XPS, UV-vis DRS, EIS, PL spectroscopy, and photocurrent response. SEM, TEM, and XPS results demonstrate the creation of Bi4Ti3O12/Ag3PO4 heterojunction with obvious interfacial interaction between Bi4Ti3O12 and Ag3PO4. PL spectra, EIS spectra, and photocurrent responses reveal that the composites display an enhanced separation efficiency of photogenerated electron-hole pairs, which is due to the charge transfer between Bi4Ti3O12 and Ag3PO4. Rhodamine B (RhB) was chosen as the target organic pollutant to evaluate its degradation behavior over Bi4Ti3O12/Ag3PO4 composites under simulated sunlight irradiation. Compared to bare Bi4Ti3O12 and Ag3PO4 nanoparticles, the composites exhibit a significantly enhanced photocatalytic activity. The highest photocatalytic activity is observed for the 10% Bi4Ti3O12/Ag3PO4 composite with 10% Bi4Ti3O12 content, which is about 2.6 times higher than that of bare Ag3PO4. The photocatalytic mechanism involved was investigated and discussed in detail. PMID- 29181632 TI - Microbial lipolytic fusion enzymes: current state and future perspectives. AB - Genetic fusion of coding ORFs or connection of proteins in a post translational process are rather novel techniques to build products called fusion proteins that possess combined characteristics of their parental biomolecules. This attractive strategy used to create new enzymes not only diversifies their functionality by improving thermostability, thermo- and catalytic activity, substrate specificity, regio- or enantio-selectivity but also facilitates their purification and increases their yield. Many examples of microbial synthetic fusion biocatalysts are associated with fused enzymes that are involved in biomass degradation. However, one of the leading production segments is occupied by microbial lipolytic enzymes (lipases and esterases). As powerful biocatalysts these enzymes found their application in detergent, food, oil and fat, pulp and paper, leather, textile, cosmetics, biodiesel production industries. Moreover, lipolytic enzymes market is predicted to maintain leadership up to the year of 2024 and exceed millions of dollars. Recently, creation of lipolytic fusion biocatalysts for industrial applications gained more attention since it is not only a way of achievement of enzymes with improved properties but also a way to reduce industrial energy costs and ensure other economic benefits. This paper provides a comprehensive review on current state of microbial lipolytic fusion enzymes and their future potential. PMID- 29181633 TI - Amphiregulin regulates proliferation and migration of HER2-positive breast cancer cells. AB - PURPOSE: Tumor initiation and progression rely on cellular proliferation and migration. Many factors are involved in these processes, including growth factors. Amphiregulin (AREG) is involved in normal mammary development and the development of estrogen receptor (ER)-positive breast cancer. The aim of this project was to determine if AREG is involved in the proliferation and progression of HER2-positive breast cancer. METHODS: Mouse cell lines MMTV-neu, HC-11 and COMMA-D, as well as human cell lines MCF10A, SKBR3, HCC1954 and BT474 were used. Real-time PCR was used to quantify AREG expression and neutralizing antibodies were used to reduce the autocrine/paracrine effects of AREG. Transfections using siRNA and shRNA were used to knockdown AREG expression in the cancer cell lines. Free-floating sphere formation, colony forming, scratch wound and Transwell assays were used to assess the proliferation, tumor forming and migratory capacities of transfected cancer cells. RESULTS: We found AREG expression in both normal epithelial cell lines and tumor-derived cell lines. Knockdown of AREG protein expression resulted in reduced sphere sizes and reduced sphere numbers in both mouse and human cancer cells that overexpress erbB2/HER2. AREG was found to be involved in cancer cell migration and invasion. In addition, we found that AREG expression knockdown resulted in different migration capacities in normal and erbB2/HER2 overexpressing cancer cells. CONCLUSIONS: Based on our results we conclude that AREG is involved in regulating the proliferation and migration of erbB2/HER2-positive breast cancer cells. PMID- 29181634 TI - Population structure and virulence gene profiles of Streptococcus agalactiae collected from different hosts worldwide. AB - Streptococcus agalactiae is a leading cause of morbidity and mortality among neonates and causes severe infections in pregnant women and nonpregnant predisposed adults, in addition to various animal species worldwide. Still, information on the population structure of S. agalactiae and the geographical distribution of different clones is limited. Further data are urgently needed to identify particularly successful clones and obtain insights into possible routes of transmission within one host species and across species borders. We aimed to determine the population structure and virulence gene profiles of S. agalactiae strains from a diverse set of sources and geographical origins. To this end, 373 S. agalactiae isolates obtained from humans and animals from five different continents were typed by DNA microarray profiling. A total of 242 different S. agalactiae strains were identified and further analyzed. Particularly successful clonal lineages, hybridization patterns, and strains were identified that were spread across different continents and/or were present in more than one host species. In particular, several strains were detected in both humans and cattle, and several canine strains were also detected in samples from human, bovine, and porcine hosts. The findings of our study suggest that although S. agalactiae is well adapted to various hosts including humans, cattle, dogs, rodents, and fish, interspecies transmission is possible and occurs between humans and cows, dogs, and rabbits. The virulence and resistance gene profiles presented enable new insights into interspecies transmission and make a crucial contribution to the identification of suitable targets for therapeutic agents and vaccines. PMID- 29181635 TI - Caryophyllales are the main hosts of a unique set of ectomycorrhizal fungi in a Neotropical dry forest. AB - The ectomycorrhizal symbiosis was long thought to be restricted to temperate forests. However, as tropical forests have been explored, it has become clear that these habitats host unique ectomycorrhizal (ECM) fungi. We have been exploring tropical dry forests (TDF), which are endangered terrestrial ecosystems and hotspots of endemism. Since Fabaceae is the main plant family in this environment, we hypothesized that trees in this lineage would be the main ECM hosts. We sequenced the ITS rDNA region from fungi and both rbcL and trnL cpDNA from plants to identify both symbiotic partners from root tips. The systematic position of each symbiont was confirmed by Bayesian phylogenetic inference. We identified 20 plant species belonging to 10 families that hosted 19 unique ECM fungal species from 5 lineages. Most ECM fungi were associated with Caryophyllales, not with Fabaceae. Achatocarpus and Guapira, the main hosts, are scattered throughout the forest and are not in monodominant patches. The low ECM fungal diversity can be explained by the low density of host plants and their high specificity. Our results indicate that Caryophyllales is an important order of tropical ECM hosts with at least four independent evolutionary lineages that have evolved the ability to form ectomycorrhizae. PMID- 29181636 TI - Accounting for local adaptation in ectomycorrhizas: a call to track geographical origin of plants, fungi, and soils in experiments. AB - Local adaptation, the differential success of genotypes in their native versus foreign environments, can influence ecological and evolutionary processes, yet its importance is difficult to estimate because it has not been widely studied, particularly in the context of interspecific interactions. Interactions between ectomycorrhizal (EM) fungi and their host plants could serve as model system for investigations of local adaptation because they are widespread and affect plant responses to both biotic and abiotic selection pressures. Furthermore, because EM fungi cycle nutrients and mediate energy flow into food webs, their local adaptation may be critical in sustaining ecological function. Despite their ecological importance and an extensive literature on their relationships with plants, the vast majority of experiments on EM symbioses fail to report critical information needed to assess local adaptation: the geographic origin of the plant, fungal inocula, and soil substrate used in the experiment. These omissions limit the utility of such studies and restrict our understanding of EM ecology and evolution. Here, we illustrate the potential importance of local adaptation in EM relationships and call for consistent reporting of the geographic origin of plant, soil, and fungi as an important step towards a better understanding of the ecology and evolution of EM symbioses. PMID- 29181637 TI - Further investigation of relationships between membrane fluidity and ethanol tolerance in Saccharomyces cerevisiae. AB - Membrane lipid unsaturation index and membrane fluidity have been related to yeast ethanol stress tolerance in published studies, however findings have been inconsistent. In this study, viability reduction on exposure to 18% (v/v) ethanol was compared to membrane fluidity determined by laurdan generalized polarization. Furthermore, in the determination of viability reduction, we examined the effectiveness of two methods, namely total plate count and methylene violet staining. We found a strong negative correlation between ethanol tolerance and membrane fluidity, indicated by negative Pearson correlation coefficients of - 0.79, - 0.65 and - 0.69 for Saccharomyces cerevisiae strains A12, PDM and K7, respectively. We found that lower membrane fluidity leads to higher ethanol tolerance, as indicated by decreased viability reduction and higher laurdan generalized polarization in respiratory phase compared to respiro-fermentative phase cells. Total plate count better differentiated ethanol tolerance of yeast cells in different growth phases, while methylene violet staining was better to differentiate ethanol tolerance of the different yeast strains at a particular culture phase. Hence, both viability assessment methods have their own advantages and limitations, which should be considered when comparing stress tolerance in different situations. PMID- 29181638 TI - Synergetic Effect of Graphene and MWCNTs on Microstructure and Mechanical Properties of Cu/Ti3SiC2/C Nanocomposites. AB - Multi-walled carbon nanotubes (MWCNTs) and graphenes have been taken for novel reinforcements due to their unique structure and performance. However, MWCNTs or graphenes reinforced copper matrix composites could not catch up with ideal value due to reinforcement dispersion in metal matrix, wettability to metal matrix, and composite material interface. Taking advantage of the superior properties of one dimensional MWCNTs and two-dimensional graphenes, complementary performance and structure are constructed to create a high contact area between MWCNTs and graphenes to the Cu matrix. Mechanical alloying, hot pressing, and hot isostatic pressing techniques are used to fabricate Cu matrix self-lubricating nanocomposites. Effects of MWCNTs and graphenes on mechanical properties and microstructures of Cu/Ti3SiC2/C nanocomposites are studied.

AB - AIM: The aim of this case-series study is to evaluate the prevalence of mucositis, peri-implantitis, and survival and success rates of oxide-coated implants in subjects treated for periodontitis. MATERIALS AND METHODS: Twenty four subjects treated for generalized chronic periodontitis (GCP) and five treated for generalized aggressive periodontitis (GAP) were orally rehabilitated with a total of 130 dental implants. Subjects were examined 2 to 4 weeks prior to extraction of non-retainable teeth and at insertion of superstructure. Additional examinations were performed during a 3-month recall schedule over a 3- to 6-year follow-up period. Radiographs were taken after insertion of the superstructure and 1, 3, and 5 years later. RESULTS: The results showed implant survival rates of 97.1% in GCP subjects versus 96.2% in GAP subjects. The implant success rate was 77.9% in GCP subjects and 38.5% in GAP subjects. In GCP subjects, mucositis was present in 7.7% and peri-implantitis in 12.5% of the implants. In GAP subjects, 28.0% of the implants showed mucositis and 32.0% peri-implantitis. Implant failure, mucositis, and peri-implantitis were more evident in GAP subjects. Peri-implantitis was more prevalent for implants in the maxilla and implants >10 mm. After 5 years, the mean peri-implant bone loss in GAP subjects was 2.89 mm and in GCP subjects 1.38 mm. CONCLUSIONS: Periodontally diseased subjects treated in a supportive periodontal therapy can be successfully rehabilitated with oxide-coated dental implants for a follow-up period of 3- to 6 years. Implants in the maxilla and GAP subjects were more susceptible to mucositis and peri-implantitis, with lower implant survival and success rates. PMID- 29181640 TI - Impact of gut microbiota on drug metabolism: an update for safe and effective use of drugs. AB - The intestinal mucosa and liver have long been considered as the main sites of drug metabolism, and the contribution of gut microbiota to drug metabolism has been under-estimated. However, it is now generally accepted that the gut microbiota plays an important role in drug metabolism prior to drug absorption or during enterohepatic circulation via various microbial enzymatic reactions in the intestine. Moreover, some drugs are metabolized by gut microbiota to specific metabolite(s) that cannot be formed in the liver. More importantly, the metabolism of drugs by gut microbiota prior to absorption can alter the systemic bioavailability of certain drugs. Therefore, understanding drug metabolism by gut microbiota is critical for explaining changes in the pharmacokinetics of drugs, which may cause significant alterations in drug-induced pharmacodynamics and toxicities. In this review, we describe recent progress with regard to the role of metabolism by gut microbiota in some drug-induced alterations of either pharmacological or toxicological effects to emphasize the clinical importance of gut microbiota for safe and effective use of drugs. PMID- 29181641 TI - Effect of photobiomodulation on connective tissue remodeling and regeneration of skeletal muscle in elderly rats. AB - The purpose of this study was to evaluate the effects of low-level laser therapy (LLLT) on morphological aspects, IL-6 and IL-1beta expressions, as well as the distribution and organization of collagen in the tibialis anterior (TA) muscle of elderly rats submitted to cryoinjury. Histological photomicrographs were taken of TA muscles stained with HE and picrosirius red. Immunohistochemistry was used for the evaluation of IL-6 and IL-1beta. Male Wistar rats, aged 20 months, were distributed into three groups: (1) control animals not injured or treated with LLLT (n = 5), (2) cryoinjury without LLLT treatment (n = 15), and (3) cryoinjury treated with infrared LLLT (n = 15). LLLT was applied to the TA 2 h after of the injury induction and consisted of daily applications until the sacrifice (1, 3, and 7 days). The following parameters were used: lambda = 780 nm, power density 1 W/cm2, output power 40 mW, 10 s per point, 8 points, and 3.2 J of total energy. In the histomorphological analysis, the treated group exhibited a significant decrease in inflammatory infiltrate (p < 0.001) as well as an increase immature fibers and new blood vessels at 7 days compared to the untreated group (p < 0.05). Furthermore, treatment induced a better collagen distribution and organization at 7 days in comparison to the untreated group (p < 0.05). In conclusion, LLLT demonstrated a modulatory effect on the muscle repair process in elderly animals with regard to the collagen remodeling and morphological aspects of muscle tissue. PMID- 29181642 TI - Laser photobiomodulation in pressure ulcer healing of human diabetic patients: gene expression analysis of inflammatory biochemical markers. AB - Pressure ulcers (PU) are wounds located mainly on bone surfaces where the tissue under pressure suffers ischemia leading to cellular lesion and necrosis , its causes and the healing process depend on several factors. The aim of this study was evaluating the gene expression of inflammatory/reparative factors: IL6, TNF, VEGF, and TGF, which take part in the tissue healing process under effects of low level laser therapy (LLLT). In order to perform lesion area analysis, PUs were photographed and computer analyzed. Biochemical analysis was performed sa.mpling ulcer border tissue obtained through biopsy before and after laser therapy and quantitative real-time PCR (qRT-PCR) analysis. The study comprised eight individuals, mean age sixty-two years old, and sacroiliac and calcaneous PU, classified as degree III and IV according to the National Pressure Ulcer Advisory Panel (NPUAP). PUs were irradiated with low-level laser (InGaAIP, 100 mW, 660 nm), energy density 2 J/cm2, once a day, with intervals of 24 h, totaling 12 applications. The lesion area analysis revealed averaged improvement of the granulation tissue size up to 50% from pre- to post-treatment. qRT-PCR analysis revealed that IL6 values were not significantly different before and after treatment, TNF gene expression was reduced, and VEFG and TGF-beta gene expression increased after treatment. After LLLT, wounds presented improvement in gross appearance, with increase in factors VEFG and TGF-beta, and reduction of TNF; despite our promising results, they have to be analyzed carefully as this study did not have a control group. PMID- 29181643 TI - Vibrational spectroscopy of muscular tissue intoxicated by snake venom and exposed to photobiomodulation therapy. AB - The pathogenesis of myonecrosis caused by myotoxins from bothropic venom is associated with local extracellular matrix (ECM) disintegration, hemorrhage, and inflammation. Search for alternative methods associated with serum therapy is mandatory to neutralize the fast development of local damage following snakebites. The experimental use of photobiomodulation therapy (PBMT) in murine models has shown promising results relative to structural and functional recovery from bothropic snakebite-induced myonecrosis. This study pioneered in using Raman and Fourier transform infrared (FTIR) spectroscopies to characterize biochemical alterations in the gastrocnemius that had been injected with Bothrops jararacussu venom and exposed to local PBMT. Results show that vibrational spectra from lyophilized and diluted venom (1307 cm -1) was also found in the envenomed gastrocnemius indicating venom presence in the unirradiated muscle 48 h post injection; but any longer visible after PBMT at this time exposure or 72 h post injection regardless irradiated or not. Raman and FTIR analyses indicated that the bands with higher area and intensity were 1657 and 1547 cm-1 and 1667 and 1452 cm-1, respectively; all are assignments for proteins, especially collagen, and are higher in the PBMT-exposed gastrocnemius. The infrared spectra suggest that laser treatment was able to change protein in tissue and that such change indicates collagen as the main target. We hypothesize that the findings reflect remodeling of ECM with key participation of collagen and faster tissue recovery for an anabolic condition.

AB - Development of a truly effective medication for treatment of cocaine abuse has been a grand challenge. There is no FDA-approved therapeutic agent specific for cocaine addiction or overdose. An enzyme therapy using an efficient cocaine metabolizing enzyme could be a promising treatment strategy for cocaine overdose and addiction. One of our previously designed cocaine hydrolases (CocHs), known as CocH1, was fused with human serum albumin (HSA) to prolong the biological half life. The fusion protein CocH1-HSA is an investigational new drug (IND) approved by the FDA for clinical trials in cocaine addiction treatment, but not in cocaine overdose/toxicity treatment. In the present study, we aimed to evaluate the pharmacokinetic profile of CocH1-HSA and its effectiveness for cocaine toxicity treatment in male and female rats and demonstrate the clinical potential. The data demonstrate that enzyme CocH1-HSA has very similar pharmacokinetic profile in male and female rats. For both male and female rats, the enzyme can rapidly eliminate cocaine even if the cocaine dose is as high as 180 mg/kg (LD100). Based on the animal data, whenever the enzyme is given to a living subject, the remaining cocaine in the body will be converted rapidly to physiologically inactive metabolites and, thus, reverse the cocaine toxicity and help the subject to recover. So, an enzyme therapy using CocH1-HSA can effectively treat cocaine toxicity and prevent the subject from further damage by cocaine. The data obtained clearly demonstrate the promising clinical potential of CocH1-HSA in cocaine overdose treatment for both genders. PMID- 29181646 TI - Robiginitalea sediminis sp. nov., isolated from a sea cucumber culture pond. AB - A Gram-stain negative, aerobic, non-motile, orange and rod/coccoid-shaped bacterium, designated O458T, was isolated from sediment collected from a sea cucumber culture pond located in Rongcheng, Shandong province, China (122 degrees 14'E, 36 degrees 54'N). Comparative analysis of 16S rRNA gene sequences revealed that strain O458T is a member of the genus Robiginitalea and is closely related to Robiginitalea biformata (95.7% sequence similarity) and Robiginitalea myxolifaciens (94.9%). Its DNA G+C content was 55.2 mol%. The strain grew at temperatures between 15 and 45 degrees C (optimum 33 degrees C), from pH 6.5 to 8.5 (optimum pH 7.0-7.5) and between 1.0 and 6.0% (w/v) NaCl (optimum 2.0%). Strain O458T was found to contain menaquinon-6 (MK-6) as the only respiratory quinone, iso-C15:0, iso-C17:0 3-OH and Summed feature 1 (iso-C15:1 H and/or iso C13:0 3-OH) as the major fatty acids. The major polar lipids were phosphatidylethanolamine (PE) and four unidentified lipids (L1, L2, L3 and L4). On the basis of the results of the phylogenetic and phenotypic analyses it is suggested that strain O458T represents a novel species of the genus Robiginitalea, for which the name Robiginitalea sediminis sp. nov. is proposed. The type strain is O458T (=KCTC 52898T=MCCC 1H00190T). PMID- 29181648 TI - Molecular characterization of cytosolic cysteine synthase in Mimosa pudica. AB - In the cysteine and mimosine biosynthesis process, O-acetyl-L-serine (OAS) is the common substrate. In the presence of O-acetylserine (thiol) lyase (OASTL, cysteine synthase) the reaction of OAS with sulfide produces cysteine, while with 3-hydroxy-4-pyridone (3H4P) produces mimosine. The enzyme OASTL can either catalyze Cys synthesis or both Cys and mimosine. A cDNA for cytosolic OASTL was cloned from M. pudica for the first time containing 1,410 bp nucleotides. The purified protein product from overexpressed bacterial cells produced Cys only, but not mimosine, indicating it is Cys specific. Kinetic studies revealed that pH and temperature optima for Cys production were 6.5 and 50 degrees C, respectively. The measured Km, Kcat, and Kcat Km-1 values were 159 +/- 21 uM, 33.56 s-1, and 211.07 mM-1s-1 for OAS and 252 +/- 25 uM, 32.99 s-1, and 130.91 mM 1s-1 for Na2S according to the in vitro Cys assay. The Cy-OASTL of Mimosa pudica is specific to Cys production, although it contains sensory roles in sulfur assimilation and the reduction network in the intracellular environment of M. pudica. PMID- 29181647 TI - The role of plant hormones during grafting. AB - For millennia, people have cut and joined different plant tissues together through a process known as grafting. By creating a chimeric organism, desirable properties from two plants combine to enhance disease resistance, abiotic stress tolerance, vigour or facilitate the asexual propagation of plants. In addition, grafting has been extremely informative in science for studying and identifying the long-distance movement of molecules. Despite its increasing use in horticulture and science, how plants undertake the process of grafting remains elusive. Here, we discuss specifically the role of eight major plant hormones during the wound healing and vascular formation process, two phenomena involved in grafting. We furthermore present the roles of these hormones during graft formation and highlight knowledge gaps and future areas of interest for the field of grafting biology. PMID- 29181650 TI - Reconstitutive approach for investigating plant vascular development. AB - Plants generate various tissues and organs via a strictly regulated developmental program. The plant vasculature is a complex tissue system consisting of xylem and phloem tissues with a layer of cambial cells in between. Multiple regulatory steps are involved in vascular development. Although molecular and genetic studies have uncovered a variety of key factors controlling vascular development, studies of the actual functions of these factors have been limited due to the inaccessibility of the plant vasculature. Thus, to obtain a different perspective, culture systems have been widely used to analyze the sequential processes that occur during vascular development. A tissue culture system known as VISUAL, in which molecular genetic analysis can easily be performed, was recently established in Arabidopsis thaliana. This reconstitutive approach to vascular development enables this process to be investigated quickly and easily. In this review, I summarize our recent knowledge of the regulatory mechanisms underlying vascular development and provide future perspectives on vascular analyses that can be performed using VISUAL. PMID- 29181649 TI - Cell-cell communications and molecular mechanisms in plant sexual reproduction. AB - Sexual reproduction is achieved by precise interactions between male and female reproductive organs. In plant fertilization, sperm cells are carried to ovules by pollen tubes. Signals from the pistil are involved in elongation and control of the direction of the pollen tube. Genetic, reverse genetic, and cell biological analyses using model plants have identified various factors related to the regulation of pollen tube growth and guidance. In this review, I summarize the mechanisms and molecules controlling pollen tube growth to the ovule, micropylar guidance, reception of the guidance signal in the pollen tube, rupture of the pollen tube to release sperm cells, and cessation of the tube guidance signal. I also briefly introduce various techniques used to analyze pollen tube guidance in vitro. PMID- 29181652 TI - Repeat cytoreduction and hyperthermic intraperitoneal chemotherapy for recurrent peritoneal carcinomatosis of appendiceal origin. AB - BACKGROUND: The purpose of this study was to clarify the role of repeat cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) in the management of recurrent peritoneal carcinomatosis of appendiceal origin. METHODS: Data were retrieved on 42 patients who underwent CRS + HIPEC; 29 repeat surgical procedures were performed in 13 patients. RESULTS: Complete cytoreduction was achieved in 12 of 13 patients by the second CRS. Repeat recurrence was detected in 11 patients, eight of whom underwent a third CRS. The peritoneal cancer index decreased from initial CRS to repeat CRS but was still higher than 18 in nine patients at the second CRS. Preoperative chemotherapy was given to three patients with early recurrence. Grade 3-5 morbidity and 90-day mortality were not significantly different between initial and repeat CRS. Five year survival rates after first and second CRS were 75.5 and 67.7%, respectively. Complete cytoreduction at second CRS was a significant prognostic factor. Among patients with recurrence after the second CRS, patients who underwent a third CRS showed a better prognosis than those who did not. CONCLUSIONS: Repeat CRS is oncologically beneficial, and the morbidity rate was as high as that of initial CRS. Complete cytoreduction was the key to successful long-term results. Although further recurrence was common, aggressive resection was useful, even in cases of diffuse recurrence. PMID- 29181651 TI - Risk of fatigue in cancer patients receiving anti-EGFR monoclonal antibodies: results from a systematic review and meta-analysis of randomized controlled trial. AB - BACKGROUND: To evaluate the association between fatigue and anti-epidermal growth factor receptor monoclonal antibodies (anti-EGFR MAbs), we conducted the first meta-analysis to access the incidence and risk of fatigue associated with anti EGFR MAbs. METHODS: Electronic databases were searched for randomized controlled trials (RCTs) published up to February 2017. Eligible studies were selected according to PRISMA statement. Incidence rates, risk ratio (RRs), and 95% confidence intervals (CIs) were calculated using fixed-effects or random-effects models. Outcomes of quality were summarized in accordance with the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology. RESULTS: Thirty-five RCTs (including 15,622 patients) were included; median follow-up ranged from 8.1 to 71.4 months, and the fatigue events were recorded and graded according to the Common Toxicity Criteria for Adverse Events version 2.0 or 3.0 in most of the included trials. For patients receiving anti-EGFR MAbs, the overall incidence of all-grade and high-grade fatigue was 54.1% and 10.5%, respectively. Compared with control, anti-EGFR MAbs significantly increased the risk of all-grade fatigue (RR 1.10, 95% CI, 1.05-1.14, moderate-quality evidence) and high-grade fatigue (RR 1.31, 95% CI, 1.19-1.45, moderate-quality evidence). No significant differences among subgroup analyses (anti-EGFR MAbs, tumor type, and median follow-up) on high-grade fatigue were observed. No evidence of publication bias was observed. CONCLUSION: The present study suggested that anti EGFR MAbs may increase the risk of fatigue in cancer patients.

PMID- 29181655 TI - The organisation of the acute ischemic stroke management: key notes of the Italian Neurological Society and of the Italian Stroke Organization. AB - The main aim of acute ischemic stroke treatment is the as much possible prompt, safe and effective arterial recanalisation, in order to restore reperfusion into the ischemic brain area. The procedures obtaining this result are rapidly evolving and in the last years, we observed new evidences that affirmed the therapeutical benefit of the concomitant treatment using endovenous thrombolysis and mechanical thrombectomy in selected patients with ischemic stroke. However, all treatments are time-sensitive and the main limitation for their application is represented by the time. For this reason, the optimisation of the acute stroke management that includes a pre-hospital and an in-hospital phase is essential to reduce the avoidable delay, increasing the number of patients potentially treatable. The purpose of this document is to define the main elements and to suggest the principal key points constituting the optimal pathway of stroke management in Italian care settings, in line with the recommendations coming from the current national and international guidelines.

PMID- 29181658 TI - Effect of ferric citrate hydrate on FGF23 and PTH levels in patients with non dialysis-dependent chronic kidney disease with normophosphatemia and iron deficiency. AB - BACKGROUND: In patients with normophosphatemia with chronic kidney disease (CKD), fibroblast growth factor 23 (FGF23) and parathyroid hormone (PTH) increase urinary phosphate excretion while maintaining serum phosphate within the normal range. Recent reports have shown that, in this stage, phosphate binders do not decrease serum FGF23 and PTH levels. Iron deficiency promotes transcription of FGF23 and iron-supplementation for iron deficiency decreases serum FGF23 levels. We hypothesized that ferric citrate hydrate, an iron-based phosphate binder, will decrease serum FGF23 levels in patients with non-dialysis-dependent CKD with normophosphatemia and iron deficiency. METHODS: This was a single-center, randomized, open-label interventional study. The inclusion criteria were as follows: (1) eGFR < 45 mL/min/1.73 m2, (2) normophosphatemia, (3) iron deficiency. Patients were assigned to the following groups: ferric citrate hydrate (FCH)-group, sodium ferrous citrate (SFC)-group, and control-group. After 12 weeks of intervention, we evaluated serum FGF23 levels and CKD-mineral bone disorder markers. RESULTS: There were 17 patients in the FCH-group, 14 in the SFC group, and 9 in the control-group. The serum ferritin levels increased in the FCH group and SFC-group compared with baseline. Serum FGF23 levels were unchanged; the change in the FCH-group was from 52.91 RU/mL (42.48-72.91) to 40.00 RU/mL (30.30-58.13) (P = 0.1764). However, in the FCH-group, serum PTH levels significantly decreased compared with baseline, from 68.00 pg/mL (49.00-141.00) to 60.00 pg/mL (44.00-144.00) (P = 0.0101). CONCLUSION: Iron-based phosphate binder did not decrease serum FGF23 levels, but decreased serum PTH levels. PMID- 29181659 TI - Decrease in toe pinch force in male type 2 diabetic patients with diabetic nephropathy. AB - BACKGROUND: The purpose of this cross-sectional study was to investigate the toe pinch force (TPF) of type 2 diabetic patients with diabetic nephropathy by disease stage, and to clarify the factors affecting the TPF. METHODS: Seventy four men with diabetic nephropathy (age: 62.7 +/- 8.9 years, duration of diabetes: 14.2 +/- 8.6 years) were enrolled. According to the staging of diabetic nephropathy, TPF and knee extension force (KEF) were compared among three groups: normoalbuminuria, microalbuminuria, and overt nephropathy. In addition, we investigated factors influencing TPF and KEF by performing multiple regression analysis. RESULTS: Normoalbuminuria group, microalbuminuria group, and overt nephropathy group included 26, 25, and 23 patients, respectively. The TPF of the overt nephropathy group (3.15 +/- 0.75 kg) was significantly lower than that of the normoalbuminuria (4.2 +/- 0.7 kg, p < 0.001) and microalbuminuria groups (3.65 +/- 0.81 kg, p = 0.022). The KEF of the overt nephropathy group (37.1 +/- 8.3 kgf) was significantly lower than that of the normoalbuminuria group (44.8 +/ 8.3 kgf, p = 0.010). Multiple regression analysis revealed that diabetic polyneuropathy (DPN) and diabetic nephropathy were determinant factors of the TPF; and age, body mass index, and diabetic nephropathy were determinant factors of the KEF. CONCLUSION: We found in male patients with diabetic nephropathy, the TPF and KEF decreased with progression of diabetic nephropathy. Furthermore, our findings suggest diabetic nephropathy and DPN are critically involved in the reduction of TPF and KEF. PMID- 29181660 TI - Pre-operative and post-operative estimated glomerular filtration rate in Japanese patients with urological malignancies. AB - BACKGROUND: The suitable methods evaluating glomerular filtration rate (GFR) have not been established in patients undergoing radical nephrectomy (RN) or radical nephroureterectomy (RNU) due to urological malignancies in Japan as well as worldwide. METHODS: We examined the relationship between creatinine clearance based measured GFR (mGFR) versus estimated GFR (eGFR) calculated by 3 popular equations, 4-variable Modification of Diet in Renal Disease equation adjusted by Japanese correction coefficient (cmMDRD), 3-variable MDRD equation for Japanese population (eGFRcreat), and Chronic Kidney Disease-Epidemiology Collaboration equation adjusted by Japanese correction coefficient (cmCKD-EPI) in Japanese patients who had undergone RN or RNU due to renal cell carcinoma or upper tract urothelial carcinoma before and after surgery. RESULTS: Among the 3 equations examined, eGFRcreat was the closest to mGFR, although each eGFR was significantly higher than mGFR in the pre-operative period. In the post-operative period, cmMDRD and eGFRcreat, but not cmCKD-EPI, were comparable to mGFR. Each of eGFR was significantly correlated with mGFR in both the pre-operative and post operative periods. Similar results were obtained by the subanalysis of the patients with pre-operative mGFR of < 60 mL/min/1.73 m2. Results of kappa statistics also showed that eGFRcreat was most appropriate to estimate GFR both before and after heminephrectomy, when cut-off value of GFR of < 60 mL/min/1.73 m2 was used. CONCLUSION: Results of the present study suggest that eGFRcreat is likely to be the most appropriate equation for patients undergoing RN or RNU due to urological malignancies. However, more precise equations will be required for accurately estimating GFR. PMID- 29181661 TI - Role of Sertoli and Leydig Cells in the Regulation of Spermatogonial Stem Cell and Development of Reproductive Disorders in Male C57Bl/6 Mice with Type 1 Diabetes Mellitus. AB - Course administration streptozotocin to male C57Bl/6 mice induces a complex of symptoms typical of type 1 diabetes mellitus: hyperglycemia and insulin deficiency, focal inflammatory infiltration of the pancreas, destructive changes in the Langerhans islets, damage to the insular apparatus (reduced number of PDX1+ cells and insulin expression by the secreting cells). Male reproductive disorder are serious complications of type 1 diabetes mellitus. In "diabetic" mice, interstitial edema with inflammatory infiltration and microvascular disorders in the testicular tissue are observed, the number of endothelial precursors (CD45-/CD31+) and the total number and percentage of motile spermatozoa decreased, immature spermatogenic epithelium cells are desquamated of into the lumen of the tubules. Disturbances in the proliferation and differentiation of various spermatogonial stem cell populations (c-kit-/CD90+, c kit+/CD90+, and CD51-/CD24+/CD52+) in diabetes can be explained by the inhibitory influence of inflammatory factors on testosterone-producing Leydig cells. PMID- 29181662 TI - Inhibition of the Expression of Inducible NO Synthase by Neuroactive Amino Acid Derivatives Phenibut and Glufimet In Vitro and Ex Vivo. AB - The effects of glufimet and phenibut (glutamic acid and GABA derivatives, respectively) on concentration of inducible NO synthase and cGMP in LPS-activated mouse peritoneal macrophages and on NO end products in their culture medium were examined in vitro and ex vivo. Addition of LPS into culture medium elevated concentration of NO metabolites in this medium and increased concentration of inducible NO synthase and cGMP in the lysates of peritoneal macrophages, whereas incubation of the cells with examined agents applied at concentration of 10-5 M diminished these indices. Similar results were obtained with intraperitoneal injection of LPS, glufimet, and phenibut. In culture medium containing peritoneal macrophages from the mice injected with LPS (100 MUg/kg), the concentrations of inducible NO synthase and cGMP as well as the total concentration of nitrite and nitrate ions increased, whereas in culture medium with the cells from LPS-exposed mice treated with glufimet (28.7 mg/kg) and phenibut (50 mg/kg) these indices significantly decreased. PMID- 29181663 TI - Gene TNF Polymorphism -308G>A (rs1800629) and Its Relationship with the Efficiency of Ursodeoxycholic Acid Therapy in Patients with Nonalcoholic Stetohepatitis. AB - Association of TNF gene polymorphism -308G>A with the development of nonalcoholic steatohepatitis in the Russian population was revealed. Carriers of allele A of the TNF gene marker -308G>A have significantly higher risk of nonalcoholic steatohepatitis development: OR=1.69 (1.05; 2.71). Allele A carriage by this marker predicts an increase in the basal HDL level and a decrease in LDL and IL 10 levels in the blood of healthy subjects. Patients with nonalcoholic steatohepatitis, differing by the TNF gene -308G>A marker genotype, differ by the time course of the markers of hepatocellular damage (ALT, AST), activity of hepatocyte apoptosis (tissue polypeptide-specific antigen), and activation of specific humoral immunity (gamma-globulin) in response to therapy with ursodeoxycholic acid in a dose of 10-15 mg/kg over 4-6 weeks. Carriers of allele A of the TNF gene polymorphic marker -308G>A are more sensitive to ursodeoxycholic acid therapy than carriers of GG genotype.

AB - Changes in the structure of the olfactory bulbs after long-term intranasal administration of pesticide rotenone, a classical inductor of parkinsonism, to rats were studied by the methods of immunomorphology. In rats intranasally receiving rotenone in a dose of 2.5 mg/kg every other day over 2 weeks, a decrease in the density of dopaminergic neurons and the area of astrocyte processes in the olfactory bulbs, activation of microglia in the glomerular layer, and enhanced alpha-synuclein phosphorylation and its accumulation in the bodies of mitral layer neurons were observed. The observed changes agree with the hypothesis on pathological alpha-synuclein transport via the olfactory route in Parkinson's disease and confirm relevance of the rotenone model of Parkinson's disease for studies of the pathological accumulation of alpha-synuclein. PMID- 29181665 TI - Effect of Neoadjuvant Chemoradiation Therapy on Proteasome Pool in Rectal Cancer. AB - In untreated rectal cancer patients, the chymotrypsin-like activity of proteasomes in tumor tissue was 3-fold higher than that in conventionally normal tissue, which is explained by up-regulation of expression of immunoproteasomes and total pool of proteasomes. After neoadjuvant chemoradiation therapy, expressions of the total pool of proteasomes and immunoproteasomes in the tumor as well as the relative ratios of these indices to those in conventionally normal tissue were smaller by 1.4-3.3 times in comparison with the untreated patients. These changes were paralleled with pronounced (4.5-fold) down-regulation of proteasome activity in the tumor and a 3.7-fold decrease of activity ratio for the proteasomes in tumor and in conventionally normal tissue. The number of immunoproteasome subunits and the chymotrypsin-like activity of proteasomes can be viewed as potential markers to prognosticate effectiveness of neoadjuvant chemoradiation therapy in rectal cancer patients.

AB - We studied the effect of Gly-His -Lys tripeptide administered intraperitoneally in doses of 5, 15, 50 and 150 MUg/kg on pain-induced aggressive-defensive behavior. A foot-shock model of aggression in rats grouped in pairs in an electrified chamber was used. Analgesic and antiaggresiogenic effects of the peptide were demonstrated. It was found the L-lysine residue plays the key role in these effects, because they were observed under the influence of L-lysine administration in doses close to its equimolar content in the studied tripeptide. PMID- 29181667 TI - Comparison of the Pharmacological Effects of Dimeric Dipeptide Nerve Growth Factor Mimetic GK-2 and Mexidol on the Model of Ischemic Stroke in Rats. AB - We compared the effects of GK-2 (dimeric dipeptide mimetic of nerve growth factor) and Mexidol (standard preparation for the therapy of stroke) on rat model of transient occlusion of the middle cerebral artery. GK-2 and Mexidol were administered intraperitoneally in the most active doses (1 and 100 mg/kg, respectively) 6 h after surgery and then once a day for 6 days. The preparations reduced the volume of cerebral infarction (by 60 and 30%, respectively). At the same time, GK-2 had a pronounced and statistically more reliable effect in a dose that is lower by two orders of magnitude. In addition, GK-2 significantly reduced the neurological deficit in the limb placement test, while Mexidol was ineffective in this test. PMID- 29181668 TI - Melatonin-Aluminum Oxide-Polymethylsiloxane Complex on Apoptosis of Liver Cells in a Model of Obesity and Type 2 Diabetes Mellitus. AB - We studied the effects of a melatonin-aluminum oxide-polymethylsiloxane complex (complex M) on the expression of apoptosis regulators Bcl-2 and Bad in the liver of homozygous db/db BKS.Cg-Dock7m+/+Leprdb/J mice with obesity and type 2 diabetes. Complex M or placebo was administered daily through the gastric tube during weeks 8-16 of life. In mice with type 2 diabetes mellitus receiving placebo, enhanced immunohistochemical reactions for proapoptotic Bad protein and weak response for anti-apoptotic Bcl-2 protein were observed. Administration of complex M shifted the ratio of apoptosis regulators: the area of Bcl-2 expression significantly increased and against the background of reduced Bad expression area. These findings attest to antiapoptotic effect of complex M in the liver on the model of type 2 diabetes mellitus. PMID- 29181669 TI - Inhibitory Effect of Interferons on Contractive Activity of Bovine Mesenteric Lymphatic Vessels and Nodes. AB - We studied the effect of IFNalpha-2b and IFNbeta-1a on phasic and tonic contractions of isolated bovine mesenteric lymphatic vessels and nodes. IFNalpha 2b and IFNbeta-1a in concentrations of 250-1000 U/ml produced dose-dependent negative chronotropic and inotropic effects on spontaneous phasic contractions and tonus of lymphatic vessels and nodes. In de-endothelialized lymphatic vessels and nodes, IFNalpha-2b and IFNbeta-1a in the same concentrations had less pronounced inhibitory effect on spontaneous contraction and tonus. L-NAME (100 MUM) and charybdotoxin (0.1 MUM with 0.5 MUM apamine) significantly attenuated the inhibitory effect of IFNalpha-2b on phasic and tonic contractions of lymph nodes. L-NAME (100 MUM) and indomethacin (10 MUM) significantly reduced the IFNalpha-2b-induced inhibitory effect on phasic and tonic contractions of lymph node. These results indicate that IFNalpha-2b and IFNbeta-1a have a pronounced inhibitory effect on the phasic and tonic contractions of bovine mesenteric lymphatic vessels and nodes. The responses are endothelium-dependent and are determined by production of NO and endothelium-dependent hyperpolarizing factor by endotheliocytes in lymphatic vessels and by production of NO and prostacyclin by endotheliocytes in the lymphatic nodes.

The parameters R, K, MA, S, TMA, and J changed to hypocoagulation direction in comparison to the control. At this, Selank demonstrated the maximal anticoagulation potency. PMID- 29181671 TI - Modifying Effect of Autotransfusion of Mesenchymal Stromal Cells on the Production of Reactive Oxygen Species and Cytokines by Mononuclear Cells in Patients with Chronic Heart Failure. AB - We studied in vivo modifying effect of autotransfusion of human bone marrow mesenchymal stromal cells on ROS generation and production of cytokines (TNFalpha,TNFbeta, IL-1alpha, IL-10, IFNgamma, and GM-CSF) and PGE2 by mononuclear cells of patients (N=21) with chronic heart failure. These parameters were evaluated prior to (control) and after (immediately and on day 14) intravenous administration of stromal cells in doses of 100-200*106. Immediately after autotransfusion, significant increase of in vitro zymosan-induced chemiluminescence of blood mononuclear cells from 10 patients was observed. At later terms after autotransfusion (day 14), inhibition of chemiluminescent activity of blood mononuclear cells was revealed in 50% patients. We discuss possible mechanisms of involvement of transplanted autologous bone marrow mesenchymal stromal cells in reprogramming of blood mononuclear phagocytes from the pro- to anti-inflammatory phenotype under conditions of their in vivo interaction manifesting in transition from activation to inhibition of ROS producing activity of macrophages and significant suppression of in vitro LPS induced production of TNFalpha and GM-CSF by blood mononuclears against the background of significantly elevated TNFbeta, IL-10, and IL-1alpha concentrations. PMID- 29181672 TI - Seasonal cycles of the TBE and Lyme borreliosis vector Ixodes ricinus modelled with time-lagged and interval-averaged predictors. AB - Ticks of the species Ixodes ricinus (L.) are the major vectors for tick-borne diseases in Europe. The aim of this study was to quantify the influence of environmental variables on the seasonal cycle of questing I. ricinus. Therefore, an 8-year time series of nymphal I. ricinus flagged at monthly intervals in Haselmuhl (Germany) was compiled. For the first time, cross correlation maps were applied to identify optimal associations between observed nymphal I. ricinus densities and time-lagged as well as temporal averaged explanatory variables. To prove the explanatory power of these associations, two Poisson regression models were generated. The first model simulates the ticks of the entire time series flagged per 100 m[Formula: see text], the second model the mean seasonal cycle. Explanatory variables comprise the temperature of the flagging month, the relative humidity averaged from the flagging month and 1 month prior to flagging, the temperature averaged over 4-6 months prior to the flagging event and the hunting statistics of the European hare from the preceding year. The first model explains 65% of the monthly tick variance and results in a root mean square error (RMSE) of 17 ticks per 100 m[Formula: see text]. The second model explains 96% of the tick variance. Again, the accuracy is expressed by the RMSE, which is 5 ticks per 100 m[Formula: see text]. As a major result, this study demonstrates that tick densities are higher correlated with time-lagged and temporal averaged variables than with contemporaneous explanatory variables, resulting in a better model performance. PMID- 29181674 TI - Morphological and molecular divergence of Rhipicephalus turanicus tick from Albania and China. AB - Rhipicephalus turanicus is an important tick species potentially carrying tick borne pathogens. Several tick species have obvious subspecies divergence. However few studies aimed to examine the existence of divergence within R. turanicus. Therefore, a detailed morphological and molecular analysis was conducted for comparing R. turanicus from the Mediterranean Basin (represented by Albania) and Central Asia (Northwestern China). Altogether 315 adult ticks of R. turanicus (103 from Albania and 212 from China) were morphologically and molecularly analysed. DNA samples were used for mitochondrial 16S rRNA and cox1 gene sequences analysis. In addition, as potentially genetic markers, three fragments including partial nad1-16S rRNA, nad2-cox1, cox1-tRNA-Lys, were designed and then phylogenetically analyzed. Based on detailed morphological observations, only basis capituli length:width ratio (females), the length, the width and the length:width ratio of the scutum (males) had differences between R. turanicus from China and Albania. Gene divergences of 16S rRNA, cox1, partial nad1-16S rRNA, nad2-cox1 and cox1-tRNA-Lys from China and Albania ticks were 3.53-4.84, 3.57-4.92, 3.57-4.07, 3.57-4.39 and 3.18-4.69%, respectively. The evaluated five genetic markers revealed two phylogenetic branches in R. turanicus. Obvious differences exist within R. turanicus based on morphological and genetic analysis. Three newly designed genetic markers (partial nad1-16S rRNA, nad2-cox1 and cox1-tRNA-Lys) in this study may be suitable genetic tools for identification and analysis in R. turanicus. Subspecies analysis of R. turanicus from other regions of the world should be initiated in the future. PMID- 29181676 TI - Can Vessel Invasion Change the TNM Stage in Non-small Cell Lung Cancer? A Reply. PMID- 29181675 TI - Toxicity of Juniperus oxycedrus oil constituents and related compounds and the efficacy of oil spray formulations to Dermatophagoides farinae (Acari: Pyroglyphidae). AB - The American house dust mite (AHDM), Dermatophagoides farinae Hughes (Acari: Pyroglyphidae), is recognized as an important source of allergens in the domestic environment. This study was conducted to determine whether 19 constituents from essential oil of cade, Juniperus oxycedrus L. (Cupressaceae), eight structurally related compounds, and another 16 previously known cade oil constituents were toxic for adult AHDMs and to determine the route of acaricidal action of the test compounds, as well as to assess the control efficacy of four experimental spray formulations containing the oil (10-40 mg/L sprays). In a fabric-circle contact mortality bioassay, methyleugenol (LD50, 5.82 ug/cm2) and guaiacol (8.24 ug/cm2) were the most toxic compounds against the mites, and the toxicity of these compounds and benzyl benzoate did not significantly differ. High toxicity was also observed with eugenol, m-cresol, and nerolidol (LD50, 12.52-19.52 ug/cm2), and these compounds were significantly more toxic than N,N-diethyl-3 methylbenzamide (DEET) (LD50, 37.67 ug/cm2). Cade applied as 30 or 40 mg/L experimental sprays provided 96 and 100% mortality against the mites, respectively, whereas permethrin (cis:trans, 25:75) 2.5 g/L spray treatment resulted in 17% mortality. In vapor-phase mortality tests, the compounds described were consistently more toxic in closed versus open containers, indicating that toxicity was achieved mainly through the action of vapor. Reasonable mite control in indoor environments can be achieved by spray formulation containing the 40 mg/L cade oil as potential contact-action fumigants.

AB - Ticks endure stressful off-host periods and perform as vectors of a diversity of infectious agents, thus engaging pathways that expectedly demand for autophagy. Little is known of ticks' autophagy, a conserved eukaryotic machinery assisting in homeostasis processes that also participates in tissue-dependent metabolic functions. Here, the autophagy-related ATG4 (autophagin-1), ATG6 (beclin-1) and ATG8 (LC3) mRNAs from the human diseases vector Amblyomma sculptum and the cattle tick Rhipicephalus microplus were identified. Comparative qPCR quantifications evidenced different transcriptional status for the ATG genes in the salivary glands (SG), ovaries and intestines of actively feeding ticks. These ATGs had increased relative transcription under nutrient-deprivation, as determined by validation tests with R. microplus embryo-derivative cells BME26 and A. sculptum SG explants incubations in HBSS. Starvation lead to 4-31.8* and ~ 60-500* increments on the ATGs mRNA loads in BME26 and A. sculptum SG explants, respectively. PI3K inhibitor 3MA treatment also affected ATGs expression in BME26. Some ATGs were more transcribed in the SGs than in the ovaries of cattle ticks. Amblyomma sculptum/R. microplus interspecific comparisons showed that ATG4 and ATG6 were 0.18* less expressed in A. sculptum SGs, but ~ 10-100* more expressed in their ovaries when compared to R. microplus organs. ATG4 and ATG8a transcript loads were ~ 120* and ~ 40* higher, respectively, in A. sculptum intestines when compared to cattle-ticks of similar weight category. ATGs expression in A. sculptum intestines increased with tick weight, indicating Atgs contribution to intracellular blood digestion. Possible roles of the autophagy machinery and their organ-specific expression profile on vector biology are discussed.

PMID- 29181679 TI - Impact of Neoadjuvant Chemotherapy on Nodal Disease and Nodal Surgery by Tumor Subtype. AB - BACKGROUND: Neoadjuvant chemotherapy (NAC) is known to downstage disease in the breast and increase breast conservation. It can also decrease nodal disease extent. We evaluated the impact of NAC on nodal positivity, nodal burden, and nodal surgery by tumor subtype. METHODS: All cT1-4c breast cancers from 2010 to 2014 in the National Cancer Database were evaluated, comparing patients receiving NAC with those undergoing primary surgery (PS). Rates of pathologic node-negative status (pN0) and sentinel lymph node (SLN) surgery (1-5 nodes) were compared using chi-square tests, and adjusted odds ratios (OR) were estimated. RESULTS: Of 461,549 patients, 36,715 (8.0%) received NAC and 424,834 (92.0%) had PS. In cN0 patients, pN0 rates were higher in NAC compared with PS patients in ER-/HER2+ [93.2 vs. 79.0%, odds ratio (OR) 3.64, p < 0.001], ER-/HER2- (89.9 vs. 85.2%, OR 1.55, p < 0.001), and ER+/HER2+ (84.7 vs. 78.3%, OR 1.54, p < 0.001). Patients with cT2-3, N0 tumors had significantly higher rate of SLN surgery for NAC versus PS for each biologic subtype except for ER+/HER2- tumors, amongst which this was true only for T3 tumors. In cN1-3 patients, pN0 rates after NAC were 61.3% in ER /HER2+, 47.7% in ER+/HER2+, 47.3% in ER-/HER2-, and 20.2% in ER+/HER2- and SLN surgery was highest in ER-/HER2+ (28.9%, p < 0.05 versus other subtypes). CONCLUSION: NAC increases rates of pN0 among cN0 patients compared with PS. Among cN+ patients, 20-61% undergoing NAC convert to pN0 depending on tumor type, with lowest nodal response in ER+/HER2- disease. Use of NAC results in less extensive axillary surgery than in patients treated with PS in both cN0 and cN+ disease. PMID- 29181680 TI - The Impact of Primary Tumor Location on Long-Term Survival in Patients Undergoing Hepatic Resection for Metastatic Colon Cancer. AB - BACKGROUND: The impact of primary tumor location on overall survival (OS), recurrence-free survival (RFS), and long-term outcomes has not been well established in patients undergoing potentially curative resection of colorectal liver metastases (CRLM). METHODS: A single-institution database was queried for initial resections for CRLM 1992-2004. Primary tumor location determined by chart review (right = cecum to transverse; left = splenic flexure to sigmoid). Rectal cancer (distal 16 cm), multiple primaries, and unknown location were excluded. Kaplan-Meier and Cox regression methods were used. Cure was defined as actual 10 year survival with either no recurrence or resected recurrence with at least 3 years of disease-free follow-up. RESULTS: A total of 907 patients were included with a median follow-up of 11 years; 578 patients (64%) had left-sided and 329 (36%) right-sided primaries. Median OS for patients with a left-sided primary was 5.2 years (95% confidence interval [CI] 4.6-6.0) versus 3.6 years (95% CI 3.2 4.2) for right-sided (p = 0.004). On multivariable analysis, the hazard ratio for right-sided tumors was 1.22 (95% CI 1.02-1.45, p = 0.028) after adjusting for common clinicopathologic factors. Median RFS was marginally different stratified by primary location (1.3 vs. 1.7 years; p = 0.065). On multivariable analysis, location of primary was not significantly associated with RFS (p = 0.105). Observed cure rates were 22% for left-sided and 20% for right-sided tumors. CONCLUSIONS: Among patients undergoing resection of CRLM, left-sided primary tumors were associated with improved median OS. However, long-term survival and recurrence-free survival were not significantly different stratified by primary location. Patients with left-sided primary tumors displayed a prolonged clinical course suggestive of more indolent biology. PMID- 29181681 TI - A Novel Preoperative Skeletal Muscle Measure as a Predictor of Postoperative Complications, Long-Term Survival and Tumor Recurrence for Patients with Gastric Cancer After Radical Gastrectomy. AB - BACKGROUND: Increasing numbers of studies have shown that skeletal muscle measures are closely associated with tumors. This study explored the relationship between skeletal muscle measures and short- and long-term outcomes after radical gastrectomy (RG) for gastric cancer (GC). METHODS: The study analyzed 221 GC patients who underwent RG between December 2009 and December 2010. The total psoas area (TPA) and psoas density [Hounsfield unit average calculation (HUAC)] were measured. The total psoas gauge (TPG) was created by multiplying TPA * HUAC. Low TPA, low HUAC, and low TPG were defined in the categorical analyses as the lowest quartile. Logistic regression modeling, the Kaplan-Meier method, and three step multivariate analysis were used. RESULTS: The median follow-up period was 64 months. Compared with low TPA and low HUAC, only low TPG was an independent risk factor for postoperative complications. The univariate analysis showed that low TPA, low HUAC, and low TPG were predictors of overall survival (OS), recurrence free survival (RFS), and cancer-specific survival (CCS) after surgery. The result of the three-step multivariate analysis demonstrated that low TPG was an independent risk factor for OS, RFS, and CCS. Moreover, the prognostic value of TPG was superior to that of TPA and HUAC. The patients with low TPG experienced significantly more postoperative liver recurrence than the patients with high TPG (p = 0.011). CONCLUSION: Compared with preoperative skeletal muscle quantity (TPA) and quality (HUAC), TPG can more accurately predict complications and prognosis after RG. In addition, TPG may be an indicator for the early detection of liver recurrence after RG. PMID- 29181682 TI - Effectiveness of Hepatic Artery Infusion (HAI) Versus Selective Internal Radiation Therapy (Y90) for Pretreated Isolated Unresectable Colorectal Liver Metastases (IU-CRCLM). AB - BACKGROUND: In the era of modern effective systemic chemotherapy, the comparative effectiveness of hepatic artery infusion (HAI) versus selective internal radiation therapy (yttrium-90 [Y90]) for pretreated patients with isolated unresectable colorectal liver metastasis (IU-CRCLM) remains unknown. This study sought to compare the overall survival (OS) after HAI versus Y90 for IU-CRCLM patients treated with modern chemotherapy and to perform a cost analysis of both regional methods. METHODS: This study retrospectively reviewed patients receiving HAI or Y90 in combination with modern chemotherapy as second-line therapy for IU CRCLM. Overall survival was calculated from the time of IU-CRCLM diagnosis. Uni- and multivariate models were constructed to identify independent predictors of survival. RESULTS: The inclusion criteria were met by 97 patients (48 HAI patients and 49 Y90 patients). Both groups were similar in terms of age, gender, body mass index (BMI), synchronous disease, carcinoembryonic antigen (CEA), liver tumor burden, and chemotherapy-related characteristics including use of biologics and lines of chemotherapy (all p > 0.05). The HAI group had a better OS than the Y90 group (31.2 vs. 16.3 months; p < 0.001). A trend toward reduced cost favored the HAI group (median, $29,479 vs. $39,092; p = 0.296). The multivariate analysis showed that receipt of HAI (hazard ratio 0.465) and number of chemotherapy lines (HR 0.797) were associated with improved OS from the date of IU-CRCLM diagnosis. CONCLUSIONS: This is the first study to evaluate the comparative effectiveness of HAI versus Y90 in the era of modern chemotherapy, and the findings suggests that HAI is associated with better survival than Y90 for patients with pretreated IU CRCLM. PMID- 29181683 TI - Analysis of the Infiltrative Features of Chordoma: The Relationship Between Micro Skip Metastasis and Postoperative Outcomes. AB - BACKGROUND: Chordomas are very rare primary malignant bone tumors that arise commonly from the sacrum (50-60%) and clivus (25-35%). Chordomas have a high rate of recurrence. The authors confirmed a unique histologic infiltration pattern of chordomas that resembles a skip-metastatic lesion in normal tissue around tumor, which they named "micro-skip metastasis." This study aimed to examine the correlations between the clinicopathologic features of chordomas, including micro skip metastasis, and the clinical outcomes, including overall survival, local recurrence-free survival, and distant metastasis-free survival. METHODS: The study analyzed histopathologic and clinical data from patients with sacral chordomas who underwent en bloc resection from July 1991 through July 2014. Cases with a minimum follow-up period shorter than 20 months after resection were excluded. Kaplan-Meier survival analyses with log-rank tests were performed for overall survival, metastasis-free survival, and recurrence-free survival. RESULTS: The study retrospectively reviewed 40 patients. The mean follow-up period was 98.2 months (range 22-297 months). The local recurrence rate was 41.3%. Micro-skip metastases, observed in 17 patients (42.5%), were associated with a significantly increased risk of local recurrence (p = 0.023) but not with overall survival or distant metastasis-free survival. Poorer overall survival was associated with histologic vascular invasion (p = 0.030) and a greater maximum tumor diameter (p = 0.050). CONCLUSIONS: The presence of micro-skip metastasis was associated with a higher rate of local recurrence. The maximum tumor diameter and the presence of histologic vascular invasion were associated with poorer overall survival.

PMID- 29181686 TI - Administration of a Sol-Gel Formulation of Phenylephrine Using Low-Temperature Hollow Microneedle for Treatment of Intermittent Fecal Incontinence. AB - PURPOSE: A low temperature hollow microneedle system was devised to deliver sol gel transition formulation near the surface of the skin for extended release and local delivery of drug by a non-invasive method. This new system can improve treatment of intermittent fecal incontinence. METHOD: The low-temperature system was integrated with a hollow microneedle to maintain the low temperature of the sol formulation. Various sol-gel formulations using Pluronic F-127 (PF-127) and Hydroxy-propyl-methyl-cellulose (HPMC) were prepared, and their gelation temperature, flow property, and diffusion retardation were observed. Resting anal sphincter pressure in response to a phenylephrine (PE) sol-gel formulation was measured using an air-charged catheter. The biocompatibility of the sol-gel PE formulation was evaluated by observing the immunological response. RESULTS: When the PF-127 25%, HPMC 1% and PE formulation (PF25-HPMC1-PE) was injected through the peri-anal skin of the rat in vivo, the highest pressure on the anal sphincter muscle occurred at 6-8 h and anal pressure increased and lasted twice as long as with the phosphate-buffered saline (PBS)-PE formulation. There was no significant difference in the number of mast cells after administration into the rat in vivo between the PF25-HPMC1-PE formulation and the PBS-PE formulation. CONCLUSION: The combination of a low-pain hollow microneedle system and an injectable sol-gel formulation improved the efficacy of treatment of intermittent fecal incontinence. A low-temperature hollow microneedle system using a sol-gel formulation has many applications in medical treatments that require depot effect, local targeting, and pain control. PMID- 29181687 TI - miR-542-3p Appended Sorafenib/All-trans Retinoic Acid (ATRA)-Loaded Lipid Nanoparticles to Enhance the Anticancer Efficacy in Gastric Cancers. AB - PURPOSE: In this study, miR-542-3p appended SRF/ATRA-loaded solid lipid nanoparticle was successfully prepared and demonstrated for its therapeutic efficacy against gastric cancers. METHODS: The particles were nanosized and typically spherical in shape. In vitro release study showed that release of ATRA was significantly slower compared to that of SRF from the NPs. RESULTS: MTT assay showed that miR-542-3p have a strong inhibitory effect on the proliferation of MGC-803 cancer cells in a typical dose dependent manner. Nanocarrier encapsulation of SRF + ATRA induced a significantly higher cytotoxic effect compared to either individual drug or cocktail combinations indicating that the cellular uptake of different formulations was rate limiting factor in the therapeutic efficacy. Importantly, miR-542-3p-based miSRNP exhibited an extremely significant toxic effect compared to any other treated group. Importantly, miSRNP induced a significantly higher early (~55%) and late (~15%) apoptotic effect in gastric cancer cells. In vivo anticancer analysis results clearly suggest that nanoparticle encapsulation of combination of SRF and miRNA (with miRNA) will have greater antitumor efficacy in tumor mice. CONCLUSION: Overall, unique combination of miRNA coupled with SRF + ATRA in a lipid nanocarrier could be a promising therapeutic approach in gastric cancer treatment.

AB - The occurrence of the copepod Lamproglena cleopatra Humes, 1957, parasitising freshwater fishes in the Limpopo River System is presented, along with new morphological data. This crustacean was originally described parasitising a cyprinid (Labeo forskalii Ruppell) from the River Nile, Egypt. During 2014-2015 crustacean samples were collected from the gills of three cyprinid fish species, Labeo rosae Steindachner from Flag Boshielo Dam, Labeo molybdinus Du Plessis from Nwanedi-Luphephe Dam in South Africa, and Labeo ruddi Boulenger from the River Bubye in Zimbabwe. The specimens from the present study were morphologically similar regardless of the host, but exhibited some morphometric intraspecific differences in comparison with the type-specimen from Egypt. A description of L. cleopatra copepodid III stage and a taxonomic key to Lamproglena spp. is provided. PMID- 29181689 TI - Do Parents and Clinicians Agree on Ratings of Autism-Related Behaviors at 12 Months of Age? A Study of Infants at High and Low Risk for ASD. AB - Given the emphasis on early screening for ASD, it is crucial to examine the concordance between parent report and clinician observation of autism-related behaviors. Similar items were compared from the First Year Inventory (Baranek et al. First-Year Inventory (FYI) 2.0. University of North Carolina, Chapel Hill, 2003), a parent screener for ASD, and the ADOS-2 Toddler Module (Lord et al. 2013), a standardized ASD diagnostic tool. Measures were administered concurrently to 12-month-olds at high and low risk for ASD. Results suggest that clinicians and parents rated behaviors similarly. In addition, both informants rated high-risk infants as more impaired in several social-communication behaviors. Furthermore, the format of questions impacted agreement across observers. These findings have implications for the development of a new generation of screening instruments for ASD. PMID- 29181690 TI - Association of maternal depression with dietary intake, growth, and development of preterm infants: a cohort study in Beijing, China. AB - This study aimed to explore the association of maternal depression with nutrient intake, growth, and development of preterm infants. A cohort study of 201 infants was conducted in Beijing. Based on the gestational age of an infant and status of the mother, the infants were divided into four groups: non-depression-fullterm (64), non-depression-preterm (70), depression-fullterm (36), and depression preterm (31). Data on sociodemographic characteristics, nutritional intake, growth, and developmental status of children at 8 months (corrected ages) were collected using a quantitative questionnaire, a 24-Hour Dietary Recall, anthropometric measurements, and the Bayley-III scale. A multivariate analysis was used to evaluate the effects of maternal depression and preterm birth on infant growth and development. The energy, protein, and carbohydrate intake in the depression group was lower than the recommended amounts. The depression preterm groups indicated the lowest Z-scores for length and weight and the lowest Bayley-III scores. Preterm infants of depressed mothers are at high risks of poor growth and development delay. PMID- 29181691 TI - Irreversible phenotypic perturbation and functional impairment of B cells during HIV-1 infection. AB - Human immunodeficiency virus type 1 (HIV-1) infection can damage humoral immunity. The knowledge of B cell perturbations during chronic HIV-1 infection and their recovery after combined antiretroviral therapy (cART) is not complete yet, and thus attempts to further improve humoral immunity are impeded. In this study, an HIV-1 chronically infected cohort with similar demographics, infection history, genetic background, and HIV-1 genotype was established to probe B cell perturbations. Results showed that the B cells from this cohort were highly activated and prone to cell death, and B cell compartments were altered significantly. Notably, although cART partially reversed the hyperactivation and reduced tissue-like memory B cells, other B cell perturbations, including impaired expression of survival factor Bcl-2, costimulatory molecules, and shrunken resting memory B cells, were irreversible. Further functional characterization revealed that the influenza HAspecific antibody-secreting cells were significantly lower during HIV-1 infection, whereas the recalled antibody response to HIV-1-specific antigens was decreased after cART. Finally, CpG plus R848 treatment increased the survival of B cells and memory B cells in vitro from HIV-1-infected patients. In conclusion, this study identified irreversible B cell immune perturbations in chronic HIV-1 infections regardless of cART and proposed the potential strategy to enhance B cell functions through the improvement of cell survival. PMID- 29181692 TI - Serum metabolites and risk of myocardial infarction and ischemic stroke: a targeted metabolomic approach in two German prospective cohorts. AB - Metabolomic approaches in prospective cohorts may offer a unique snapshot into early metabolic perturbations that are associated with a higher risk of cardiovascular diseases (CVD) in healthy people. We investigated the association of 105 serum metabolites, including acylcarnitines, amino acids, phospholipids and hexose, with risk of myocardial infarction (MI) and ischemic stroke in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam (27,548 adults) and Heidelberg (25,540 adults) cohorts. Using case-cohort designs, we measured metabolites among individuals who were free of CVD and diabetes at blood draw but developed MI (n = 204 and n = 228) or stroke (n = 147 and n = 121) during follow-up (mean, 7.8 and 7.3 years) and among randomly drawn subcohorts (n = 2214 and n = 770). We used Cox regression analysis and combined results using meta-analysis. Independent of classical CVD risk factors, ten metabolites were associated with risk of MI in both cohorts, including sphingomyelins, diacyl-phosphatidylcholines and acyl-alkyl-phosphatidylcholines with pooled relative risks in the range of 1.21-1.40 per one standard deviation increase in metabolite concentrations. The metabolites showed positive correlations with total- and LDL-cholesterol (r ranged from 0.13 to 0.57). When additionally adjusting for total-, LDL- and HDL-cholesterol, triglycerides and C reactive protein, acyl-alkyl-phosphatidylcholine C36:3 and diacyl phosphatidylcholines C38:3 and C40:4 remained associated with risk of MI. When added to classical CVD risk models these metabolites further improved CVD prediction (c-statistics increased from 0.8365 to 0.8384 in EPIC-Potsdam and from 0.8344 to 0.8378 in EPIC-Heidelberg). None of the metabolites was consistently associated with stroke risk. Alterations in sphingomyelin and phosphatidylcholine metabolism, and particularly metabolites of the arachidonic acid pathway are independently associated with risk of MI in healthy adults. PMID- 29181693 TI - Cost-effectiveness analysis of patient self-testing therapy of oral anticoagulation. AB - Patient Self-testing (PST) could be an option for present anticoagulation therapy monitoring, but current evidence on its cost-effectiveness is limited. This study aims to estimate the cost-effectiveness of PST to other different care approaches for anticoagulation therapy in Thailand, a low-to-middle income country (LMIC). A Markov model was used to compare lifetime costs and quality-adjusted life years (QALYs) accrued to patients receiving warfarin through PST or either anticoagulation clinic (AC) or usual care (UC). The model was populated with relevant information from literature, network meta-analysis, and database analyses. Incremental cost-effectiveness ratios (ICERs) were presented as the year 2015 values. A base-case analysis was performed for patients at age 45-year old. Sensitivity analyses including one-way and probabilistic sensitivity analyses (PSA) were constructed to determine the robustness of the findings. From societal perspective, PST increased QALY by 0.87 and costs by 112,461 THB compared with UC. Compared with AC, PST increased QALY by 0.161 and costs by 21,019 THB. The ICER with PST was 128,697 (3625 USD) and 130,493 THB (3676 USD) per QALY gained compared with UC and AC, respectively. The probability of PST being cost-effective is 74.1% and 51.9%, compared to UC and AC, respectively, in Thai context. Results were sensitive to the efficacy of PST, age and frequency of hospital visit or self-testing. This analysis suggested that PST is highly cost effective compared with usual care and less cost-effective against anticoagulation clinic. Patient self-testing strategy appears to be economically valuable to include into healthcare system within the LMIC context. PMID- 29181695 TI - MEMRI reveals altered activity in brain regions associated with anxiety, locomotion, and cardiovascular reactivity on the elevated plus maze in the WKY vs SHR rats. AB - Individuals with anxiety/depression often have exaggerated cardiovascular responses to stressful stimuli and a comorbidity with hypertension. Alternatively, individuals with hypertension can be more anxious. In the present study cardiovascular changes were evaluated during behavioral testing of anxious behavior on the elevated plus maze (EPM) in the spontaneously hypertensive rat (SHR), a rodent model of neurogenic hypertension, and compared to the response of the more anxious, but normotensive, Wistar-Kyoto rat (WKY). Manganese-enhanced magnetic resonance imaging (MEMRI) was used to identify regional differences in baseline brain activity. Parallel to indicators of elevated behavioral anxiety on the EPM, WKYs had a greater increase in blood pressure but not heart rate when compared to the SHR while on the EPM. Associated with differences in anxiety related behavior and autonomic responses, we observed increased baseline activity in the amygdala, central gray, habenula and interpeduncular nucleus with MEMRI of the WKY compared to the SHR. Conversely, elevated baseline brain activity was found in regions associated with blood pressure control and system arousal, including the hypothalamus, locus coeruleus and pedunculopontine tegmental nucleus, in the SHR vs WKY, in-line with increased resting blood pressure and increased mobility in this strain. Lastly, reduced activity in hippocampal regions was identified in the SHR compared to the WKY and may be associated with cognitive impairment previously reported in the SHR. Thus, autonomic reactivity may be a true measure of stress in rodent models of anxiety and MEMRI presents a powerful technique to uncover novel brain mechanisms of blood pressure control. PMID- 29181694 TI - Infection prevention and control in ultrasound - best practice recommendations from the European Society of Radiology Ultrasound Working Group. AB - OBJECTIVES: The objective of these recommendations is to highlight the importance of infection prevention and control in ultrasound (US), including diagnostic and interventional settings. METHODS: Review of available publications and discussion within a multidisciplinary group consistent of radiologists and microbiologists, in consultation with European patient and industry representatives. RECOMMENDATIONS: Good basic hygiene standards are essential. All US equipment must be approved prior to first use, including hand held devices. Any equipment in direct patient contact must be cleaned and disinfected prior to first use and after every examination. Regular deep cleaning of the entire US machine and environment should be undertaken. Faulty transducers should not be used. As outlined in presented flowcharts, low level disinfection is sufficient for standard US on intact skin. For all other minor and major interventional procedures as well as all endo-cavity US, high level disinfection is mandatory. Dedicated transducer covers must be used when transducers are in contact with mucous membranes or body fluids and sterile gel should be used inside and outside covers. CONCLUSIONS: Good standards of basic hygiene and thorough decontamination of all US equipment as well as appropriate use of US gel and transducer covers are essential to keep patients safe. MAIN MESSAGES: * Transducers must be cleaned/disinfected before first use and after every examination. * Low level disinfection is sufficient for standard US on intact skin. * High level disinfection is mandatory for endo-cavity US and all interventions. * Dedicated transducer covers must be used for endo-cavity US and all interventions. * Sterile gel should be used for all endo-cavity US and all interventions. PMID- 29181696 TI - Comparison of clinical remission and survival between CLAG and FLAG induction chemotherapy in patients with refractory or relapsed acute myeloid leukemia: a prospective cohort study. AB - PURPOSE: To compare the clinical remission and survival between CLAG and FLAG induction chemotherapy in treating patients with refractory or relapsed acute myeloid leukemia (R/R AML). METHODS: 103 R/R AML patients were consecutively enrolled in this prospective cohort study. 55 patients were treated by CLAG induction chemotherapy as follows: 5 mg/m2/day cladribine (days 1-5); 2 g/m2/day cytarabine (days 1-5) and 300 MUg/day filgrastim (days 0-5). While 48 patients were treated by FLAG: 30 mg/m2/day fludarabine (days 1-5), 2 g/m2/day cytarabine (days 1-5), and 300 MUg/day filgrastim (days 0-5). RESULTS: CLAG induction chemotherapy achieved 61.7% complete remission rate (CR) and 78.7% overall remission rate (ORR), which was similar with FLAG chemotherapy which realized 48.7% CR and 69.2% ORR. No difference of overall survival (OS) was discovered between two groups either. Age cytarabine 60 years, secondary disease, poor risk stratification and BM blast >= 42.7% and second or higher salvage therapy were independent factors for worse prognosis. Subgroups analysis revealed that in patients with second or higher salvage therapy, CLAG seemed to achieve a higher CR than FLAG. And in patients with relapsed disease, poor risk stratification or CR at first induction, CLAG seemed to realize a prolonged OS compared to FLAG. CONCLUSION: CLAG was equally effective to FLAG induction chemotherapy in total R/R AML patients, while CLAG seemed to be a better option than FLAG in patients with relapsed disease, poor risk stratification, CR at first induction or second or higher salvage therapies. PMID- 29181697 TI - Kernel-Based Visual Hazard Comparison (kbVHC): a Simulation-Free Diagnostic for Parametric Repeated Time-to-Event Models. AB - Repeated time-to-event (RTTE) models are the preferred method to characterize the repeated occurrence of clinical events. Commonly used diagnostics for parametric RTTE models require representative simulations, which may be difficult to generate in situations with dose titration or informative dropout. Here, we present a novel simulation-free diagnostic tool for parametric RTTE models; the kernel-based visual hazard comparison (kbVHC). The kbVHC aims to evaluate whether the mean predicted hazard rate of a parametric RTTE model is an adequate approximation of the true hazard rate. Because the true hazard rate cannot be directly observed, the predicted hazard is compared to a non-parametric kernel estimator of the hazard rate. With the degree of smoothing of the kernel estimator being determined by its bandwidth, the local kernel bandwidth is set to the lowest value that results in a bootstrap coefficient of variation (CV) of the hazard rate that is equal to or lower than a user-defined target value (CVtarget). The kbVHC was evaluated in simulated scenarios with different number of subjects, hazard rates, CVtarget values, and hazard models (Weibull, Gompertz, and circadian-varying hazard). The kbVHC was able to distinguish between Weibull and Gompertz hazard models, even when the hazard rate was relatively low (< 2 events per subject). Additionally, it was more sensitive than the Kaplan-Meier VPC to detect circadian variation of the hazard rate. An additional useful feature of the kernel estimator is that it can be generated prior to model development to explore the shape of the hazard rate function. PMID- 29181699 TI - Benefits, benefits, once more benefits... with no risk? Stop overlooking the harms of medicines. AB - Consideration of drug benefits and harms is asymmetric. Approval of drugs is mainly based on efficacy, while the assessment of their safety is left to post marketing commitments or spontaneous reporting. Benefits are overestimated as a result of pharmaceutical companies' advertisements, the paucity of independent information, and the scant understanding of the effectiveness of medicines in real life. Polypharmacy in older adults-even during the last period of their life reflects the tendency to assign priority to efficacy and overlook harms, although nobody knows what happens when three or more drugs are given chronically. Medical journals and public research funding projects do not pay enough attention to drug toxicity. We call for a sense of purpose by all those involved in medicine to tackle this problem. European and national agencies and health authorities should promote and support independent information and experimental and clinical studies on drug toxicity. Information should rely not just on spontaneous reporting but also on active pharmacovigilance. The benefit-harm profile of drugs should be periodically reviewed in the light of toxic effects that come to light over the years. Potential interactions within polytherapies should be sought by re assessing the pharmacokinetics and pharmacodynamics of their components.

PMID- 29181698 TI - Pharmacokinetics of CYP2C9, CYP2C19, and CYP2D6 substrates in healthy Chinese and European subjects. AB - PURPOSE: The aim of this analysis is to compare the pharmacokinetics of drug substrates in healthy Chinese and European subjects of aligned CYP2C9, CYP2C19, or CYP2D6 enzyme activity, providing further insight into drivers of interethnic differences in pharmacokinetics. METHODS: Following identification of appropriate drug substrates, a comprehensive and structured literature search was conducted to identify single-dose pharmacokinetic data in healthy Chinese or European subjects with reported CYP2C9, CYP2C19, or CYP2D6 activity (genotype or phenotype). The ratio of drug AUC in the Chinese and European subjects classified with aligned enzyme activity was calculated (ethnicity ratio (ER)). RESULTS: For 22/25 drugs identified, the ERs calculated indicated no or only limited interethnic differences in exposure (0.05). CONCLUSIONS: MXD could promote collagen degradation and reverse pancreatic fifi brosis in CP rats via a mechanism involve up-regulation of MMP13 expression. PMID- 29181734 TI - Pleiotropy of cardiometabolic syndrome with obesity-related anthropometric traits determined using empirically derived kinships from the Busselton Health Study. AB - Over two billion adults are overweight or obese and therefore at an increased risk of cardiometabolic syndrome (CMS). Obesity-related anthropometric traits genetically correlated with CMS may provide insight into CMS aetiology. The aim of this study was to utilise an empirically derived genetic relatedness matrix to calculate heritabilities and genetic correlations between CMS and anthropometric traits to determine whether they share genetic risk factors (pleiotropy). We used genome-wide single nucleotide polymorphism (SNP) data on 4671 Busselton Health Study participants. Exploiting both known and unknown relatedness, empirical kinship probabilities were estimated using these SNP data. General linear mixed models implemented in SOLAR were used to estimate narrow-sense heritabilities (h 2) and genetic correlations (r g) between 15 anthropometric and 9 CMS traits. Anthropometric traits were adjusted by body mass index (BMI) to determine whether the observed genetic correlation was independent of obesity. After adjustment for multiple testing, all CMS and anthropometric traits were significantly heritable (h 2 range 0.18-0.57). We identified 50 significant genetic correlations (r g range: - 0.37 to 0.75) between CMS and anthropometric traits. Five genetic correlations remained significant after adjustment for BMI [high density lipoprotein cholesterol (HDL-C) and waist-hip ratio; triglycerides and waist-hip ratio; triglycerides and waist-height ratio; non-HDL-C and waist-height ratio; insulin and iliac skinfold thickness]. This study provides evidence for the presence of potentially pleiotropic genes that affect both anthropometric and CMS traits, independently of obesity. PMID- 29181735 TI - [Oral anticoagulation and platelet inhibition after atrial appendage occlusion]. AB - In Europe left atrial appendage occluders (LAAO) are most frequently used in patients with contraindications for oral anticoagulation (OAC); therefore, the classical therapeutic OAC scheme from the PROTECT-AF trial (vitamin K antagonist plus acetylsalicylic acid) is usually changed to dual anti-platelet therapy (DAPT) after implantation of a Watchman(r) or Amulet(r) LAAO (St. Jude Medical/Abbott, Eschborn, Germany). For many years, patients with an LAAO received DAPT for 1-6 months. The current standard comprises DAPT for 3 months, followed by permanent acetylsalicylic acid monotherapy if the transesophageal echocardiogram excludes a thrombus at the site of the LAAO. In patients with high risk of bleeding, anti-platelet therapy can be stopped at 3 months after an individual risk-benefit calculation. There are no randomized studies on the risk of bleeding and stroke/embolism in patients with an LAA occluder under DAPT versus OAC. Experience from the EWOLUTION registry shows that NOACs may be used as an alternative with low bleeding and thrombus risks. In patients with a suboptimal implantation result, thrombus on the LAAO or specific risk factors, variations of the standard scheme have to be applied and if necessary lifelong DAPT or NOAC therapy has to be used. Thrombi on the LAAO occur in approximately 4 6% of patients and are associated with a very low short-term stroke risk. PMID- 29181736 TI - Adoptive Induced Antigen-Specific Treg Cells Reverse Inflammation in Collagen Induced Arthritis Mouse Model. AB - Rheumatoid arthritis (RA) is a systemic autoimmune disease that may cause bone damage and worsening disability. Manipulating antigen-specific Treg cells is a promising approach to treat autoimmune disease since the immune suppressive function of Treg cells has the feature of antigen specificity which could avoid overall immune suppression. It has been known that the function of Treg cells is impaired in RA, and adoptive transfer of Treg cells is effective in suppressing RA. Here, we designed a new approach to generate antigen-specific Treg cells by culturing CD4+ T cells from mice with RA onset, and we also proved that the adoptive transfer of these antigen-specific Treg cells reversed the collagen induced arthritis (CIA) progression by suppressing the key inflammatory cytokine TNF-alpha. Further analysis showed that the transferred Treg cells were stable in vivo. These findings suggest this novel approach may have clinical applications for treatment of autoimmunity, including RA and other autoimmune disorders. PMID- 29181737 TI - MiR-548a-3p Promotes Keratinocyte Proliferation Targeting PPP3R1 after Being Induced by IL-22. AB - Psoriasis is an immune-mediated chronic skin disorder where T cells play a main role, and numerous inflammatory cytokines are implicated in its pathogenesis by initiating keratinocyte proliferation. Interleukin-22 (IL-22), an IL-10 family cytokines, is critical in the pathogenesis and development of psoriasis. To determine the target of microRNA (miR) -548a-3p and investigate its role in keratinocyte proliferation after treating human keratinocytes (HaCaT) with IL-22, we used quantitative reverse transcriptase PCR to measure the expression of miR 548a-3p in both HaCaT cells stimulated with IL-22 and psoriatic lesions, and then detected the biological function of miR-548a-3p in HaCaT cells by performing Counting Kit-8 (CCK-8) assays. Luciferase reporter assay was conducted to determine the target gene of miR-548a-3p. Immunohistochemistry and Western blot were performed to verify the target gene. Results showed that miR-548a-3p was significantly upregulated both in HaCaT cells treated with IL-22 and psoriatic lesions. The over expression of miR-548a-3p could promote the proliferation of HaCaT cells. Luciferase was mutated in the 3'UTR of PPP3R1, a gene coding Calcineurin. Immunohistochemistry and Western blot demonstrated that the expression of PPP3R1 decreased respectively in psoriatic lesions and HaCaT cells. In conclusion, the expression of miR-548a-3p is upregulated in IL-22 mediated keratinocyte proliferative disorder like psoriasis. The impact of miR-548a-3p on keratinocyte proliferation may be implemented by targeting PPP3R1 and T regulatory cells may be involved in the pathogenesis of psoriasis. PMID- 29181738 TI - Long-term survival after multidisciplinary therapy for brain metastases from asymptomatic esophageal adenocarcinoma. AB - Asymptomatic T1 (invaded submucosa) esophageal carcinoma rarely metastasizes to the brain. A 53-year-old Japanese man complaining of right hemiparesis and convulsion was admitted to our hospital. Brain imaging demonstrated a ring-like, enhanced brain tumor in the left parietal lobe. The pathological findings of the resected tumor were consistent with a metastatic adenocarcinoma from the gastrointestinal tract. Additional examinations revealed an elevated-type tumor in the lower third of the thoracic esophagus. The patient underwent thoracoscopic esophagectomy with lymph node dissection followed by reconstruction with gastric tube substitution. The immunohistochemical findings of the resected specimen were similar to those of the metastatic brain tumor. Although the patient received adjuvant chemotherapy (5-fluorouracil, docetaxel plus cisplatin), a solitary small brain metastasis was detected 4 months after esophagectomy. Excision of the sequential metastases with whole-brain radiation therapy and gamma-knife therapy were performed. The patient survived for 50 months after beginning the initial treatment. This report describes a rare case of brain metastases from T1 esophageal adenocarcinoma in a patient without gastrointestinal symptoms. PMID- 29181739 TI - Stochasticity in cultural evolution: a revolution yet to happen. AB - Over the last 40 years or so, there has been an explosion of cultural evolution research in anthropology and archaeology. In each discipline, cultural evolutionists investigate how interactions between individuals translate into group level patterns, with the aim of explaining the diachronic dynamics and diversity of cultural traits. However, while much attention has been given to deterministic processes (e.g. cultural transmission biases), we contend that current evolutionary accounts of cultural change are limited because they do not adopt a systematic stochastic approach (i.e. accounting for the role of chance). First, we show that, in contrast with the intense debates in ecology and population genetics, the importance of stochasticity in evolutionary processes has generated little discussion in the sciences of cultural evolution to date. Second, we speculate on the reasons, both ideological and methodological, why that should be so. Third, we highlight the inadequacy of genetically-inspired stochastic models in the context of cultural evolution modelling, and ask which fundamental stochastic processes might be more relevant to take up. We conclude that the field of cultural evolution would benefit from a stochastic revolution. For that to occur, stochastic models ought to be developed specifically for cultural data and not through a copy-pasting of neutral models from population genetics or ecology. PMID- 29181740 TI - Impact of mitral valve intervention with left ventricular assist device implantation on postoperative outcomes and morphologic change. AB - Although mitral regurgitation (MR) is prevalent in patients with end-stage heart failure, the impact of mitral valve (MV) surgery on outcomes after left ventricular assist device (LVAD) implantation and morphologic changes of MV remains unclear. We retrospectively reviewed 74 patients who underwent LVAD implantation as a bridge to transplant. Of these, 11 (15%) underwent MV repair concomitant with or prior to LVAD implantation, while 27 patients with preoperative significant (moderate or greater) MR did not undergo concomitant MV surgery. The mean interval between LVAD implantation and the last echocardiographic examination was 913 days. Irrespective of MV surgery, significant LV reverse remodeling including decreased LV and left atrial dimension and improved MR severity was observed in all patients except for patients with prior MV surgery. Histopathological examination of explanted hearts removed at heart transplantation (n = 69) or autopsy (n = 5) revealed that the MV annulus was still dilated (mean perimeter 11.7 cm) in the patients with preoperative significant MR and no concomitant MV surgery. Concomitant MV surgery at the time of LVAD implantation for significant MR might not be always necessary for bridge to transplant or destination therapy cases. However, it might be required in patients having potential for cardiac recovery or patients with severe pulmonary hypertension and depressed right ventricle. PMID- 29181741 TI - Longitudinal Associations between Oppositional Defiant Symptoms and Interpersonal Relationships among Chinese Children. AB - Children with oppositional defiant disorder (ODD) are at increased risk for developing poor relationships with people around them, but the longitudinal links between ODD symptoms and subsequent interpersonal functioning remain unclear. In the current study, we examined the bidirectional associations between ODD symptoms and children's relationships with parents, peers, and teachers. We included separate analyses for parent vs. teacher reports of ODD symptoms, with regard to subsequent interpersonal relationships. Participants included 256 children with ODD, recruited in China, along with their parents and teachers, assessed at three time points roughly two years apart. Parents and teachers reported child ODD symptoms at each time point, and children reported their perceptions of father- and mother-child attachment, peer relationships, and teacher-student relationships across the three time points. ODD symptoms reported either by parents or teachers predicted impairments in interpersonal functioning. Meanwhile, child interpersonal impairments with peers and teachers predicted subsequent increase in teacher-reported ODD symptoms. These findings highlight the importance of transactional models of influence-and of considering early intervention for ODD in protecting children from developing further deficits and impairments. Additionally, we discuss the perspectives of multiple informants on ODD symptoms, including their different patterns of association with subsequent interpersonal relationships.

PMID- 29181744 TI - The versatile mutational "repertoire" of Escherichia coli GroEL, a multidomain chaperonin nanomachine. AB - The bacterial chaperonins are highly sophisticated molecular nanomachines, controlled by the hydrolysis of ATP to dynamically trap and remove from the environment unstable protein molecules that are susceptible to denaturation and aggregation. Chaperonins also act to assist in the refolding of these unstable proteins, providing a means by which these proteins may return in active form to the complex environment of the cell. The Escherichia coli GroE chaperonin system is one of the largest protein supramolecular complexes known, whose quaternary structure is required for segregating aggregation-prone proteins. Over the course of more than two decades of research on GroE, it has become accepted that GroE, more specifically the GroEL subunit, is a "high-tolerance" molecular system, capable of accommodating numerous mutations, while retaining its molecular integrity. In some cases, a given site of mutation was revealed to be absolutely required for GroEL function, providing hints regarding the network of signals and triggers that propel this unique system. In other instances, however, a mutation has produced a more delicate response, altering only part of, or in some cases, only a single facet of, the molecular mechanism, and these mutants have often provided invaluable hints on the extent of the complexity underlying chaperonin assisted protein folding. In this review, we highlight some examples of the latter type of GroEL mutants which compose the unique "mutational repertoire" of GroEL and touch upon the important clues that each mutant provided to the overall effort to elucidate the details of GroE action. PMID- 29181745 TI - Salicylate Intoxication in an Infant: A Case Report. AB - In children, the most common cause of an elevated anion gap (AG) with ketonemia, ketonuria, hyperglycemia, and glycosuria is diabetic ketoacidosis. However, when the clinical history is not clear, other causes must be considered. A 9-month-old girl was transferred to our pediatric intensive care unit (PICU) because of severe metabolic acidosis. On admission, she presented with Kussmaul breathing, tachycardia, irritability, and fever. Blood gasses revealed metabolic acidosis with superimposed respiratory alkalosis and elevated AG. Fluid replacement and bicarbonate for urine alkalinization were started. Ketonemia, acidic urine with glycosuria, ketonuria, and high blood glucose prompted an insulin infusion. Measurement of plasma salicylate confirmed toxic levels. When confronted, the parents admitted to accidentally preparing the child's bottle with water containing salicylic acid 1000 mg. Although the incidence of salicylate intoxication has declined, it remains an important cause of pediatric morbidity and mortality. PMID- 29181746 TI - Severe Dehiscence of Gastrojejunal Anastomosis after Gastric Bypass: Its Cure by Using Partially Covered Stent and Avoiding Migration. AB - BACKGROUND: Gastric leak is a severe complication of gastric bypass that is associated with significant morbidity and mortality. Anastomosis dehiscence usually occurs at gastrojejunal anastomosis and can appear simultaneously with gastric leak, for which treatment can be a challenge. Fistula may have several clinical impacts, depending on patient-related factors, fistula characteristics, onset time, and therapy proposal. Abdominal toilet, drainage, gastrostomy, and revisional surgery constitute the traditional approaches to dehiscence and fistula closure, with variable results. Currently, endoscopic stents are gaining space, promoting fistula sealing, secretion deviation, treating gastric stricture, and allowing early oral diet. Herein, we present a case of severe gastrojejunal anastomosis dehiscence treated with partially covered stent. MATERIALS AND METHODS: We present a video of a 39-year-old man with a body mass index of 40 Kg/m2 who underwent a Roux-en-Y gastric bypass and presented fever and leukocytosis. Gastric leak was diagnosed 7 days after the bariatric surgery. At first, he was submitted to three reoperations: laparotomy with abdominal toilet, abdominal drain, and gastrostomy. Sepsis was controlled, but drain output maintained the same debit. On the 22nd POD, it was decided to place a metallic stent. As the first step, an endoscopist looked at the lesser curvature. There was no continuity to the alimentary limb, and the anastomosis was disrupted. Careful inflation and washing was done, allowing identification of the alimentary limb, followed by guidewire passage, with radioscopic control. Once the guidewire was positioned, stent placement was possible and safe. Upper edge of stent was placed in the lower third of the esophagus. RESULTS: Patient progressed uneventfully. After 4 weeks, stent removal was attempted. However, it was not possible due to endoluminal tissue hyperplasia. Argon plasma was used three times to promote proliferative mucosa ablation. Stent was removed after 53 days, with no migration. The abdominal drain was removed 1 week later. After 6-months follow up, the patient remains asymptomatic. CONCLUSION: Early dehiscence closure was observed, without recurrence. The use of partially covered self-expandable metallic stent is associated with lower migration rates; however, removal can be technically difficult due to tissue hyperplasia. PMID- 29181743 TI - Molecular dynamics simulation of bacterial flagella. AB - The bacterial flagellum is a biological nanomachine for the locomotion of bacteria, and is seen in organisms like Salmonella and Escherichia coli. The flagellum consists of tens of thousands of protein molecules and more than 30 different kinds of proteins. The basal body of the flagellum contains a protein export apparatus and a rotary motor that is powered by ion motive force across the cytoplasmic membrane. The filament functions as a propeller whose helicity is controlled by the direction of the torque. The hook that connects the motor and filament acts as a universal joint, transmitting torque generated by the motor to different directions. This report describes the use of molecular dynamics to study the bacterial flagellum. Molecular dynamics simulation is a powerful method that permits the investigation, at atomic resolution, of the molecular mechanisms of biomolecular systems containing many proteins and solvent. When applied to the flagellum, these studies successfully unveiled the polymorphic supercoiling and transportation mechanism of the filament, the universal joint mechanism of the hook, the ion transfer mechanism of the motor stator, the flexible nature of the transport apparatus proteins, and activation of proteins involved in chemotaxis. PMID- 29181747 TI - Unusual accidental decapitation in a road traffic incident. AB - Decapitation is an occurrence only rarely encountered in forensic medical practice. This fatality is generally most often described in pedestrians who have been run over by trains accidently or in cases of suicide, or alternatively in occupants of cars involved in high speed vehicle collisions. We report, for the first time, a case of a complete decapitation of a pedestrian as a consequence of a traffic accident. Due to a thorough medico-legal investigation of the body and the involved vehicle, we were able to reconstruct the unique dynamics of the accident and the mechanism of injury. PMID- 29181748 TI - A Quantitative Model of Early Atherosclerotic Plaques Parameterized Using In Vitro Experiments. AB - There are a growing number of studies that model immunological processes in the artery wall that lead to the development of atherosclerotic plaques. However, few of these models use parameters that are obtained from experimental data even though data-driven models are vital if mathematical models are to become clinically relevant. We present the development and analysis of a quantitative mathematical model for the coupled inflammatory, lipid and macrophage dynamics in early atherosclerotic plaques. Our modeling approach is similar to the biologists' experimental approach where the bigger picture of atherosclerosis is put together from many smaller observations and findings from in vitro experiments. We first develop a series of three simpler submodels which are least squares fitted to various in vitro experimental results from the literature. Subsequently, we use these three submodels to construct a quantitative model of the development of early atherosclerotic plaques. We perform a local sensitivity analysis of the model with respect to its parameters that identifies critical parameters and processes. Further, we present a systematic analysis of the long term outcome of the model which produces a characterization of the stability of model plaques based on the rates of recruitment of low-density lipoproteins, high density lipoproteins and macrophages. The analysis of the model suggests that further experimental work quantifying the different fates of macrophages as a function of cholesterol load and the balance between free cholesterol and cholesterol ester inside macrophages may give valuable insight into long-term atherosclerotic plaque outcomes. This model is an important step toward models applicable in a clinical setting. PMID- 29181749 TI - Fate and behavior of dissolved organic matter in a submerged anoxic-aerobic membrane bioreactor (MBR). AB - In this study, the production, composition, and characteristics of dissolved organic matter (DOM) in an anoxic-aerobic submerged membrane bioreactor (MBR) were investigated. The average concentrations of proteins and carbohydrates in the MBR aerobic stage were 3.96 +/- 0.28 and 8.36 +/- 0.89 mg/L, respectively. After membrane filtration, these values decreased to 2.9 +/- 0.2 and 2.8 +/- 0.2 mg/L, respectively. High performance size exclusion chromatograph (HP-SEC) analysis indicated a bimodal molecular weight (MW) distribution of DOMs, and that the intensities of all the peaks were reduced in the MBR effluent compared to the influent. Three-dimensional fluorescence excitation emission matrix (FEEM) indicated that fulvic and humic acid-like substances were the predominant DOMs in biological treatment processes. Precise identification and characterization of low-MW DOMs was carried out using gas chromatography-mass spectrometry (GC-MS). The GC-MS analysis indicated that the highest peak numbers (170) were found in the anoxic stage, and 54 (32%) compounds were identified with a similarity greater than 80%. Alkanes (28), esters (11), and aromatics (7) were the main compounds detected. DOMs exhibited both biodegradable and recalcitrant characteristics. There were noticeable differences in the low-MW DOMs present down the treatment process train in terms of numbers, concentrations, molecular weight, biodegradability, and recalcitrance. PMID- 29181750 TI - Experimental investigation of urea injection parameters influence on NOx emissions from blended biodiesel-fueled diesel engines. AB - The present work submits an investigation about the effect of urea injection parameters on NOx emissions from a four-stroke four-cylinder diesel engine fueled with B20 blended biodiesel. An L9(34) Taguchi orthogonal array was used to design the test plan. The results reveal that increasing urea concentration leads to lower NOx emissions. Urea flow rate increment has the same influence on NOx emission. The same result is obtained by an increase in spray angle. Also, according to the analysis of variance (ANOVA), urea concentration and then urea flow rate are the most effective design parameters on NOx emissions, while spray angle and mixing length have less influence on this pollutant emission. Finally, since the result of confirmation test is in good agreement with the predicted value based on the Taguchi technique, the predictive capability of this method in the present study could be deduced. PMID- 29181751 TI - Effect of gasoline fumes on reproductive function in male albino rats. AB - The increase in the frequency of exposure to gasoline fumes and the growing incidence of infertility among humans has been a major concern and subject of discussion over the years in Nigeria. We therefore present the reproductive effect of gasoline fumes on inhalation exposure in 40 male albino rats. The rats were randomized into five experimental treatments (T) with eight rats per treatment. T1 (control) was exposed to distilled water while T2, T3, T4, and T5 were exposed to gasoline fumes in exposure chambers for 1, 3, 5, and 9 h daily respectively for 12 weeks. Serum level of testosterone, follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin, oxidative stress markers in the testicular tissue, epididymal sperm health assessment, and testicular histopathology of the rats were used as a diagnostic marker of reproductive dysfunction. Significant (p < 0.05) alterations in the levels of all the reproductive hormones and oxidative stress markers assayed were observed in rats exposed to gasoline fume. Significant reductions (p < 0.05) in sperm count and percentage motility in the exposed rats were observed. Significant (p < 0.05) increased in abnormal sperm cells characterized by damaged head, bent tail, damaged tail, and without head were also observed in the exposed rats. Histopathologically, severe degenerative testicular architectural lesions characterized by alterations in all the generations of sperm cells and reduction of interstitial cells were seen in the exposed rats. Gasoline fume is thus said to interfere with spermatogenesis and impair fertility in male gonad.

AB - The adsorption of [Formula: see text] and [Formula: see text] by sesame straw biochars (C-300, C-500, and C-700) prepared under different temperatures (300, 500, and 700 degrees C) was investigated in this study. The physicochemical properties of the biochars were characterized using Brunauer-Emmett-Teller method, X-ray diffraction, scanning electron microscopy, and Fourier transform infrared spectrometry. In batch experiments, C-300 showed the best [Formula: see text] adsorption capacity of 3.45 mg/g because of its abundant surface functional groups at low pyrolysis temperature. C-700 achieved the optimal [Formula: see text] adsorption capacity of 34.17 mg/g because of its high Ca, Mg, and Al contents and high surface area at high pyrolysis temperature. The isothermal study showed that the Langmuir-Freundlich model could sufficiently describe the [Formula: see text] and [Formula: see text] adsorption values, indicating the multiple adsorption processes of nutrients on biochars. The maximum [Formula: see text] adsorption capacity was 93.61 mg/g on C-300, whereas the maximum [Formula: see text] adsorption capacity was as high as 116.58 mg/g on C-700. Kinetic study showed that [Formula: see text] adsorption on C-300 was mainly controlled by intraparticle diffusion, and the pseudo-second-order model could well describe [Formula: see text] adsorption on C-700.

AB - The chemical and seasonal characteristics of fine particulates in Seoul, Korea, were investigated based on 24-h integrated PM2.5 measurements made over four 1 month periods in each season between October 2012 and September 2013. The four season average concentration of PM2.5 was 37 MUg m-3, and the major chemical components were secondary inorganic aerosol (SIA) species of sulfate, nitrate, and ammonium (49%), followed by organic matter (34%). The mass concentration and most of the chemical components of PM2.5 showed clear seasonal variation, with a winter-high and summer-low pattern. The winter-to-summer sulfate ratio and the winter organic carbon (OC)-to-elemental carbon (EC) ratio were unusually high compared with those in previous studies. Strong correlations of both the sulfate level and the sulfur oxidation ratio with relative humidity, and between water soluble OC (WSOC) and SIA in winter, suggest the importance of aqueous phase chemistry for secondary aerosols. A strong correlation between non-sea salt sulfate and Na+ levels, a high Cl-/Na+ ratio, and an unusual positive correlation between the nitrogen oxidation ratio and temperature during the winter indicate the influence of transported secondary emission sources from upwind urban areas and from China across the Yellow Sea. Despite the absence of local forest fires and the regulation of wood burning, a high levoglucosan concentration and its correlations with OC and WSOC indicate that Seoul was affected by biomass burning sources in the winter. The unusually high water-insoluble OC (WIOC)-to-EC ratio in winter implies additional transported combustion sources of WIOC. The strong correlation between WIOC and levoglucosan suggests the likely influence of transported biomass burning sources on the high WIOC/EC ratio during the winter.

AB - Green and nanoacaricides including essential oil (EO) nanoemulsions are important compounds to provide new, active, safe acaricides and lead to improvement of avoiding the risk of synthetic acaricides. This study was carried out for the first time on eriophyid mites to develop nanoemulsion of garlic essential oil by ultrasonic emulsification and evaluate its acaricidal activity against the two eriophyid olive mites Aceria oleae Nalepa and Tegolophus hassani (Keifer). Acute toxicity of nanoemulsion was also studied on male rats. Garlic EO was analyzed by gas chromatography-mass spectrometry (GC-MS), and the major compounds were diallyl sulfide (8.6%), diallyl disulfide (28.36%), dimethyl tetrasulfide (15.26%), trisulfide,di-2-propenyl (10.41%), and tetrasulfide,di-2-propenyl (9.67%). Garlic oil nanoemulsion with droplet size 93.4 nm was formulated by ultrasonic emulsification for 35 min. Emulsification time and oil and surfactant ratio correlated to the emulsion droplet size and stability. The formulated nanoemulsion showed high acaricidal activity against injurious eriophyid mites with LC50 298.225 and 309.634 MUg/ml, respectively. No signs of nanoemulsion toxicity were noted in treating rats; thus, it may be considered non-toxic to mammals. Stability of garlic oil nanoemulsion, high acaricidal activity, and the absence of organic toxic solvents make the formulation that may be a possible acaricidal product. Results suggest the possibility of developing suitable natural nanoacaricide from garlic oil. PMID- 29181755 TI - Application of the Fenton's process in a bubble column reactor for hydroquinone degradation. AB - The aim of this study was to assess the degradation and mineralization of hydroquinone (HQ) by the Fenton's process in a bubble column reactor (BCR). The effect of the main operating variables, namely, air flow rate, effluent volume, hydrogen peroxide (H2O2) concentration, catalyst (Fe2+) dose, initial pH, and temperature, were assessed. For all air flow rates tested, no concentration gradients along the column were noticed, evidencing that a good mixing was reached in the BCR. For the best conditions tested ([H2O2] = 500 mg/L, [Fe2+] = 45 mg/L, T = 24 degrees C, Q air = 2.5 mL/min, pH = 3.0, and V = 5 L), complete HQ degradation was reached, with ~ 39% of total organic carbon (TOC) removal, and an efficiency of the oxidant use-eta H2O2-of 0.39 (ratio between TOC removed per H2O2 consumed normalized by the theoretical stoichiometric value); moreover, a non-toxic effluent was generated. Under these conditions, the intermediates and final oxidation compounds identified and quantified were a few carboxylic acids, namely, maleic, pyruvic, and oxalic. As a strategy to improve the TOC removal, a gradual dosage of the optimal H2O2 concentration was implemented, being obtained ~ 55% of mineralization (with complete HQ degradation). Finally, the matrix effect was evaluated, for which a real wastewater was spiked with 100 mg/L of HQ; no reduction in terms of HQ degradation and mineralization was observed compared to the solution in distilled water. PMID- 29181756 TI - Obstacle diagnosis of green competition promotion: a case study of provinces in China based on catastrophe progression and fuzzy rough set methods. AB - As "green" and "sustainable" become the new themes of regional economic development, green competitiveness will undoubtedly become a new engine for regions to solve environmental, resource use, and other global problems to fit the new development themes. Unfortunately, the performance of regional green competitiveness is not always satisfactory due to various shortcomings. In this study, we abandoned the conventional research approach that directly explores the factors that promote regional green competitiveness and analyzed, instead, the obstacles to green competitiveness among provinces in China. The barrier degree was calculated for each obstacle using a catastrophe progression method and fuzzy rough set. Results showed that (a) resource and environmental problems have become increasingly prominent and have been the most common obstacles to promoting green competitiveness of provinces in China and (b) the obstacles to improving regional green competitiveness showed spatial differences and peculiarity according to the barrier degree. The outcome of the study can help policy makers to better understand and prioritize implementation strategies to develop effective action and policy interventions toward more successful construction of regional green competitiveness. PMID- 29181757 TI - Adsorption of aquaculture pollutants using a sustainable biopolymer. AB - Intensive aquaculture needs to adopt techniques that are able to contribute towards sustainability. Closed systems that employ water recirculation can combine intensive production with environmental sustainability, since there is no exchange of water or discharge of effluents into the environment. In order to achieve this, effective filtration systems are required to ensure that the water quality is satisfactory for the cultivation of aquatic organisms. Chitosan, an industrial waste material derived from crustacean farming, is a renewable natural material that is biodegradable and possesses adsorbent characteristics. In this work, chitosan foam was incorporated in filters and was evaluated as an adsorbent of aquaculture pollutants, adding value to the material and at the same time providing a use for industrial waste. The foam was characterized by scanning electron microscopy and energy dispersive spectroscopy, apparent density, and water absorption capacity. It was used to remove ammonia, nitrite, orthophosphate, and turbidity from aquaculture effluents. The foam consisted of a bilayer with smooth and porous sides, which presented low density, flexibility, and high water absorption capacity. The best proportion of the foam, in terms of the mass of foam per volume of solution (% m v-1), was 0.10, which resulted in removal of 32.8, 57.2, 89.5, and 99.9% of ammonia, nitrite, orthophosphate, and turbidity, respectively. This biopolymer produced is biodegradable, and when saturated with organic compounds from aquaculture, and no longer suitable for reuse as a filter material, it can be employed as a fertilizer, hence closing the sustainability cycle of the aquaculture production chain. PMID- 29181758 TI - Multi-analytical methodology to diagnose the environmental impact suffered by building materials in coastal areas. AB - This work is focused on the development of an innovative multi-analytical methodology to estimate the impact suffered by building materials in coastal environments. With the aim of improving the in situ spectroscopic assessment, which is often based on XRF and Raman spectrometers, diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy was implemented in the diagnosis study. In this way, the additional benefits from DRIFT were compared to the usual in situ analyses of building materials, which often have interferences from fluorescence and reststrahlen effects. The studies were extended to the laboratory scale by MU X-ray fluorescence (MU-XRF) cross-section mapping and ion chromatography (IC), and the IC quantitative data were employed to develop thermodynamic models using the ECOS-RUNSALT program, with the aim of rationalizing the behavior of soluble salts with variations in the temperature and the relative humidity (RH). The multi-analytical methodology allowed identification of the most significant weathering agents and classification of the severity of degradation according to the salt content. The suitability of a DRIFT portable device to analyze these types of matrices was verified. Although the Kramers-Kronig algorithm correction proved to be inadequate to decrease the expected spectral distortions, the assignment was successfully performed based on the secondary bands and intensification of the overtones and decreased the time needed for in situ data collection. In addition, the pollutants' distribution in the samples and the possible presence of dangerous compounds, which were not detected during the in situ analysis campaigns, provided valuable information to clarify weathering phenomena. PMID- 29181759 TI - Theoretical investigations on the kinetics of Cl atom initiated reactions of series of 1-alkenes. AB - The temperature-dependent rate coefficients were calculated for the reactions of Cl atoms with propene (R1), 1-butene (R2), 1-pentene (R3), and 1-hexene (R4) over the temperature range of 200-400 K. Canonical variational transition state theory (CVT) with small curvature tunneling (SCT) and conventional transition state theory (CTST) in combination with MP2/6-31G(d,p), MP2/6-31G+(d,p), and MP2/6-311 + G(d,p) level of theories were used to calculate the kinetic parameters. The obtained rate coefficients at 298 K for the reactions of Cl atoms with propene, 1 butene, 1-pentene, and 1-hexene are 1.36 * 10-10 cm3 molecule-1 s-1, 1.53 * 10-10 cm3 molecule-1 s-1, 4.61 * 10-10 cm3 molecule-1 s-1, and 4.76 * 10-10 cm3 molecule-1 s-1, respectively. In all these reactions, strong negative temperature dependence was observed over the studied temperature range. Cl atom addition across the double bond is the most dominant pathway. The contribution of abstraction channels towards their global rate coefficients was observed to be increasing from propene to 1-hexane. Atmospheric implications such as effective lifetimes and thermodynamic parameters of the test molecules were investigated in the present study. PMID- 29181761 TI - Different contexts change the impression of animacy. AB - The aim of this research was to explore the effect of different spatiotemporal contexts on the perceptual saliency of animacy, and the extent of the relationship between animacy and other related properties such as emotions and intentionality. Paired-comparisons and ratings were used to compare the impressions of animacy elicited by a small square moving on the screen, either alone or in the context of a second square. The context element was either static or moving showing an animate-like or a physical-like trajectory, and the target object moved either toward it or away from it. The movement of the target could also include animacy cues (caterpillar-like expanding/contracting phases). To determine the effect of different contexts on the emergence of emotions and intentions, we also recorded and analysed the phenomenological reports of participants. The results show that the context significantly influences the perception of animacy, which is stronger in dynamic contexts than in static ones, and also when the target is moving away from the context element than when it is approaching it. The free reports reveal different proportions in emotional or intentional attributions in the different conditions: in particular, the "moving away" condition is related to negative emotions, while the "approaching" condition evokes positive emotions. Overall, the results suggest that animacy is a graded concept that can be articulated in more general characteristics, like simple aliveness, and more specific ones, like intentions or emotions, and that the spatiotemporal contingencies of the context play a crucial role in making them evident. PMID- 29181760 TI - ATP7B Mutation Detection and Pathogenicity Analysis: One Atypical Case of Wilson's Disease with Adrenocortical Insufficiency. AB - Wilson's disease (WD) is an autosomal recessive disorder caused by defective function of the copper-transporting ATP7B protein. Symptoms are typically related to the brain and liver, while endocrinologic abnormalities are rare. Here, we reported a 12-year-old female patient that was initially presented with unusual skin darkening and low serum level of adrenocorticotropic hormone and diagnosed as having adrenocortical insufficiency. We further screened the mutation in ATP7B by direct DNA sequencing and found compound heterozygous mutations: a known pathogenic mutation in exon8:c.2333G>T (Arg778Leu) inherited from her mother and a variant in intron4:c.1707 + 5G>A inherited from her father. To explore the pathogenicity of the intronic variant, a minigene splicing assay was used to determine the effects of the splicing variant by analyzing reverse transcription PCR of ATP7B minigene transcript production. The result indicated that the c.1707 + 5G>A variant resulted in exon 4 skipping. We herein identified that 1707 + 5G>A intron 4 variant is a pathogenic mutation. Molecular genetic analysis and laboratory examination definitely confirmed the patient's condition as WD. Clinical status improved considerably after penicillamine treatment. Our results extended the mutation spectrum of ATP7B gene and highlighted the importance of molecular genetic analysis for the accurate diagnosis of atypical WD. WD may have diverse presentations and should be considered in children especially presenting with adrenocortical insufficiency as initial symptom, and this study highlights the importance of screening for hormone abnormal in WD. PMID- 29181762 TI - Magnetic immobilization of bacteria using iron oxide nanoparticles. AB - Bacterial cell immobilization is a novel technique used in many areas of biosciences and biotechnology. Iron oxide nanoparticles have attracted much attention in bacterial cell immobilization due to their unique properties such as superparamagnetism, large surface area to volume ratio, biocompatibility and easy separation methodology. Adhesion is the basis behind many immobilization techniques and various types of interactions determine bacterial adhesion. Efficiency of bacterial cell immobilization using iron oxide nanoparticles (IONs) generally depends on the physicochemical properties of the IONs and surface properties of bacterial cells as well as environmental/culture conditions. Bacteria exhibit various metabolic responses upon interaction with IONs, and the potential applications of iron oxide nanoparticles in bacterial cell immobilization will be discussed in this work.

AB - Prunus cerasifera has a rich resource and a weak utilization rate and its biological functions have been investigated. We found that the contents of total phenol (TP) in leaves and branches of Prunus cerasifera were 117.8 +/- 8.8 and 100.04 +/- 0.9 mg/g, respectively; the contents of soluble condensed tannin (SCT) were 73.95 +/- 0.9 and 78.65 +/- 4.1 mg/g, respectively; the structure of SCT containing afzelechin/epiafzelechin, catechin/epicatechin, and atechin/epicatechin as the main units and the SCT from leaves and branches exhibited better anti-tyrosinase and antioxidant activities. This study could clarify Prunus cerasifera condensed tannin resource availability and lay a theoretical foundation for its development as a natural antioxidant and tyrosinase inhibitor. PMID- 29181764 TI - Exploring the Degradation of Gallotannins Catalyzed by Tannase Produced by Aspergillus niger GH1 for Ellagic Acid Production in Submerged and Solid-State Fermentation. AB - Due to great interest on producing bioactive compounds for functional foods and biopharmaceuticals, it is important to explore the microbial degradation of potential sources of target biomolecules. Gallotannins are polyphenols present in nature, an example of them is tannic acid which is susceptible to enzymatic hydrolysis. This hydrolysis is performed by tannase or tannin acyl hydrolase, releasing in this way, biomolecules with high-added value. In the present study, chemical profiles obtained after fungal degradation of tannic acid under two bioprocesses (submerged fermentation (SmF) and solid state fermentation (SSF)) were determined. In both fermentation systems (SmF and SSF), Aspergillus niger GH1 strain and tannic acid as a sole carbon source and inducer were used (the presence of tannic acid promotes production of enzyme tannase). In case of SSF, polyurethane foam (PUF) was used like as support of fermentation; culture medium only was used in case of submerged fermentation. Fermentation processes were monitored during 72 h; samples were taken kinetically every 8 h; and all extracts obtained were partially purified to obtain polyphenolic fraction and then were analyzed by liquid chromatography-mass spectrometry (LC-MS). Molecules like gallic acid and n-galloyl glucose were identified as intermediates in degradation of tannic acid; during SSF was identified ellagic acid production. The results obtained in this study will contribute to biotechnological production of ellagic acid. PMID- 29181765 TI - Periorbital actinomycosis masquerading as a cutaneous malignancy.

PMID- 29181767 TI - Frailty, diabetes, and the convergence of chronic disease in an age-related condition: a population-based nationwide cross-sectional analysis of the Mexican nutrition and health survey. AB - AIMS: To describe the associations of frailty with diabetes mellitus and related conditions in older adults. METHODS: We conducted a cross-sectional analysis of a representative sample of older adults (n = 5379). We generated a 35-item frailty index (FI) and obtained information on diabetes and related conditions (peripheral neuropathy, lower limb amputation, diabetic coma, number of physician visits due to diabetes-related conditions, all-cause hospitalizations in the past year, years since diabetes diagnosis, and type of treatment). Logistic and Poisson regression models were used to determine the associations between frailty and diabetes and its complications. RESULTS: The mean age was 70.3 years (+/- 7.8); 54.7% were women. Those with an FI <= 0.082 composed the reference group. Multivariate analysis showed an OR of 2.32 (95% CI 1.93-2.73, p < 0.001) for the association between diabetes and frailty. People who were hospitalized for any cause during the previous year, those receiving both insulin and an oral compound to manage diabetes, and those with peripheral neuropathy showed ORs of 2.32 (95% CI 1.69-3.18, p < 0.001), 5.6 (95% CI 1.58-19.8, p = 0.008), and 2.02 (95% CI 1.42-2.86, p < 0.001), respectively, for being in the most frail group. CONCLUSIONS: People with diabetes have higher frailty scores. Furthermore, older adults with diabetes and higher burden of frailty have more diabetes-related complications. PMID- 29181768 TI - Identification and feasibility of social participation initiatives reducing isolation and involving rural older Canadians in the development of their community. AB - BACKGROUND: Although some social participation initiatives exist to counter the isolation of older adults, none were identified and prioritized according to the needs of rural regional county municipalities (RCM), including in Canada. AIMS: To identify and prioritize social participation initiatives for older Canadians, and to document the feasibility of their implementation in a rural RCM. METHODS: An action research was used to identify, based on a review of scientific and grey literature, social participation initiatives, enriched and prioritized by the community. Facilitators, challenges, and advice for the implementation of these initiatives were documented through nine group discussions (n = 85). RESULTS: Two social participation initiatives were identified as more relevant to the RCM, combined and adapted as the Benevolent Community to locate and assist isolated older adults. Two other initiatives were prioritized to identify transportation needs and solutions, and create a website on social participation activities available. Most participants perceived these initiatives as feasible, and will address older adults' social participation needs. Two facilitators were a field worker for older adults and the preoccupations of the community toward isolated older adults. The main challenges concerned the difficulty in recruiting volunteers and locating isolated older adults, exacerbated by the RCM's vast territory. Main advice involved suggestions of people for the recruitment of volunteers. DISCUSSION: Through valuable collaboration with the community, initiatives were identified and prioritized, and challenges were raised, with anticipated success. CONCLUSIONS: Further studies are needed to document the implementation and effects of these initiatives on the social participation of older adults in the RCM. PMID- 29181769 TI - Cognitive functioning, subjective memory complaints and risky behaviour predict minor home injuries in elderly. AB - INTRODUCTION: Home accidents are one of the major causes of death, particularly in older people, young children and women. AIMS: The first aim of this study was to explore the role of subjective memory complaints, cognitive functioning and risky behaviour as predictors of home injuries occurred in a year in a sample of healthy Italian older adults. The second aim was to investigate the role of risky behaviour as a mediator in the relationship between subjective and objective cognitive functioning and home injuries. METHODS: One hundred thirty-three community-dwelling older people from southern Italy were administered a battery of tests to evaluate cognitive functioning, subjective memory complaints, and risky behaviour during home activities. Risky behaviour was evaluated using the Domestic Behaviour Questionnaire, created specifically for this purpose. The number of home injuries was recorded for a year throughout monthly telephone interviews. A path analysis was performed to test the following model: cognitive functioning and subjective memory complaints directly influence risky behaviour and number of accidents over a year; risky behaviour mediates the impact of cognitive functioning and subjective memory on number of accidents over a year. RESULTS: Path analysis confirmed the model tested except the role of risky behaviour as a mediator between cognitive functioning and home accidents. DISCUSSION: Risky behaviour could represent a further risk factor in cognitively intact older adults with subjective memory complaints. CONCLUSIONS: The assessment of both cognition and behaviour in elderly can make a valuable contribution in preventing home accidents in elderly. PMID- 29181770 TI - A Novel Translational Model of Spinal Cord Injury in Nonhuman Primate. AB - Spinal cord injuries (SCI) lead to major disabilities affecting > 2.5 million people worldwide. Major shortcomings in clinical translation result from multiple factors, including species differences, development of moderately predictive animal models, and differences in methodologies between preclinical and clinical studies. To overcome these obstacles, we first conducted a comparative neuroanatomical analysis of the spinal cord between mice, Microcebus murinus (a nonhuman primate), and humans. Next, we developed and characterized a new model of lateral spinal cord hemisection in M. murinus. Over a 3-month period after SCI, we carried out a detailed, longitudinal, behavioral follow-up associated with in vivo magnetic resonance imaging (1H-MRI) monitoring. Then, we compared lesion extension and tissue alteration using 3 methods: in vivo 1H-MRI, ex vivo 1H-MRI, and classical histology. The general organization and glial cell distribution/morphology in the spinal cord of M. murinus closely resembles that of humans. Animals assessed at different stages following lateral hemisection of the spinal cord presented specific motor deficits and spinal cord tissue alterations. We also found a close correlation between 1H-MRI signal and microglia reactivity and/or associated post-trauma phenomena. Spinal cord hemisection in M. murinus provides a reliable new nonhuman primate model that can be used to promote translational research on SCI and represents a novel and more affordable alternative to larger primates.

PMID- 29181773 TI - Budget Impact Analysis of PCSK9 Inhibitors for the Management of Adult Patients with Heterozygous Familial Hypercholesterolemia or Clinical Atherosclerotic Cardiovascular Disease. AB - OBJECTIVE: The aim of this study was to assess the budget impact of introducing the proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) alirocumab and evolocumab to market for the treatment of adults with heterozygous familial hypercholesterolemia or clinical atherosclerotic cardiovascular (CV) disease requiring additional lowering of low-density lipoprotein cholesterol (LDL-C). METHODS: A 3-year model estimated the costs of lipid-modifying therapy (LMT) and CV events to a hypothetical US health plan of 1 million members, comparing two scenarios-with and without the availability of PCSK9i as add-on therapy to statins. Proportions of patients with uncontrolled LDL-C despite receiving statins, and at risk of CV events, were estimated from real-world data. Total undiscounted annual LMT costs (2017 prices, including PCSK9i costs of $14,563.50), dispensing and healthcare costs, including the costs of CV events, were estimated for all prevalent patients in the target population, based on baseline risk factors. Maximum PCSK9i utilization of 1-5% over 3 years according to risk group (following the same pattern as current ezetimibe use), and 5-10% as a secondary scenario, were assumed. RESULTS: Total healthcare budget impacts per target patient (and per member) per month for years 1, 2 and 3 were $3.62($0.10), $7.22($0.20) and $10.79($0.30), respectively, assuming 1-5% maximum PCSK9i utilization, and $15.81($0.44), $31.52($0.88) and $47.12($1.31), respectively, assuming 5-10% utilization. Results were sensitive to changes in model timeframe, years to maximum PCSK9i utilization and PCSK9i costs. CONCLUSIONS: The budget impact of PCSK9i as add-on therapy to statins for patients with hypercholesterolemia is relatively low compared with published estimates for other specialty biologics. Drug cost rebates and discounts are likely to further reduce budget impact. PMID- 29181772 TI - Liver cell therapy: is this the end of the beginning? AB - The prevalence of liver diseases is increasing globally. Orthotopic liver transplantation is widely used to treat liver disease upon organ failure. The complexity of this procedure and finite numbers of healthy organ donors have prompted research into alternative therapeutic options to treat liver disease. This includes the transplantation of liver cells to promote regeneration. While successful, the routine supply of good quality human liver cells is limited. Therefore, renewable and scalable sources of these cells are sought. Liver progenitor and pluripotent stem cells offer potential cell sources that could be used clinically. This review discusses recent approaches in liver cell transplantation and requirements to improve the process, with the ultimate goal being efficient organ regeneration. We also discuss the potential off-target effects of cell-based therapies, and the advantages and drawbacks of current pre clinical animal models used to study organ senescence, repopulation and regeneration. PMID- 29181774 TI - Sequestering of damage-associated molecular patterns (DAMPs): a possible mechanism affecting the immune-stimulating properties of aluminium adjuvants. AB - Aluminium-based adjuvants (ABAs) have been used in human and veterinary vaccines for decades, and for a long time, the adjuvant properties were believed to be mediated by an antigen depot at the injection site, prolonging antigen exposure to the immune system. The depot hypothesis is today more or less abandoned, and instead replaced by the assumption that ABAs induce an inflammation at the injection site. Induction of an inflammatory response is consistent with immune activation initiated by recognition of molecular patterns associated with danger or damage (DAMPs), and the latter are derived from endogenous molecules that normally reside intracellularly. When extracellularly expressed, because of damage, stress or cell death, a sterile inflammation is induced. In this paper, we report the induction of DAMP release by viable cells after phagocytosis of aluminium-based adjuvants. Two of the most commonly used ABAs in pharmaceutical vaccine formulations, aluminium oxyhydroxide and aluminium hydroxyphosphate, induced a vigorous extracellular expression of the two DAMP molecules calreticulin and HMGB1. Concomitantly, extracellular adjuvant particles adsorbed the DAMP molecules released by the cells whereas IL-1beta, a previously reported inflammatory mediator induced by ABAs, was not absorbed by the adjuvants. Induction of extracellular expression of the two DAMP molecules was more prominent using aluminium hydroxyphosphate compared to aluminium oxyhydroxide, whereas the extracellular adsorption of the DAMP molecules was more pronounced with the latter. Furthermore, it is hypothesised how induction of DAMP expression by ABAs and their concomitant adsorption by extracellular adjuvants may affect the inflammatory properties of ABAs. PMID- 29181775 TI - Notch ligand Delta-like1 enhances degranulation and cytokine production through a novel Notch/Dok-1/MAPKs pathway in vitro. AB - Food allergy includes sensitization phase and effect phase, and effect cells degranulate and secrete cytokines in the effect phase, causing allergic clinical symptoms. We have demonstrated that Notch signaling plays an important role in the sensitization phase, but its role in effect phases still remains unclear. In this study, we investigated the role of Notch signaling in degranulation and cytokine production of the effect phase response. A RBL-2H3 cell model was used and Notch signaling was induced by priming with Notch ligands. Our results showed after priming with Notch ligand, Delta-like1(Dll1)-Fc, beta-hexosaminidase release, and cytokines production, including TGF-beta, IL-1beta, IL-4, IL-6, and IL-13, were increased significantly, and the enhancement was abolished after DAPT treatment, a gamma-secretase inhibitor, indicating that Dll1 Notch signaling enhanced RBL-2H3 cell degranulation and cytokine production. Western blot analysis showed that Dll1 Notch signaling augmented high-affinity IgE receptors mediated phosphorylation of MAPKs through suppressing the expression of downstream tyrosine kinases 1 (Dok-1). Besides, a passive systemic anaphylaxis mouse model was used to confirm the role of Notch signaling. And our data showed that allergic clinical features of mice were alleviated, and the level of degranulation was decreased significantly after inhibiting Notch signaling in vivo. Therefore, we demonstrated Notch ligand Dll1 enhanced RBL-2H3 cell degranulation and cytokine production through a novel Notch/Dok-1/MAPKs pathway, suggesting Notch signaling played a key role in the effect phase of food allergy. PMID- 29181776 TI - [Detection and prevention in later life: risk profiles for physical, psychological, social and environmental frailty.] AB - In order to provide proactive care and support for older people attention is needed for the prevention of frailty among older adults. Subsequently, accurate case finding of those who are more at risk of becoming frail is crucial to undertake specific preventive actions. This study investigates frailty and risk profiles of frailty among older people in order to support proactive detection. Hereby, frailty is conceived not only as a physical problem, but also refers to emotional, social, and environmental hazards. Using data generated from the Belgian Ageing Studies (N = 21,664 home-dwelling older people), a multinomial logistic regression model was tested which included socio-demographic and socio economic indicators as well as the four dimensions of frailty (physical, social, psychological and environmental). Findings indicate that for both men and women having moved in the previous 10 years and having a lower household income are risk factors of becoming multidimensional frail. However, studying the different frailty domains, several risk profiles arise (e. g. marital status is important for psychological frailty), and gender-specific risk groups are detected (e. g. non-married men). This paper elaborates on practical implications and formulates a number of future research recommendations to tackle frailty in an ageing society.

AB - In recent years, fluorescent cholangiography using Indocyanine green (ICG) dye has been used to aid identification of structures during robotic cholecystectomy. We sought to compare cholecystectomy with ICG dye versus laparoscopic cholecystectomy at an inner-city academic medical center. Between January 2013 and July 2016, we identified 287 patients of which 191 patients underwent laparoscopic cholecystectomy and 96 patients underwent robotic cholecystectomy with ICG dye. Preoperative risk variables of interest included age, sex, race, body mass index (BMI), and acute cholecystitis. Primary outcome of interest was conversion to open procedures while secondary outcome was length of stay. The two groups were similar in their BMI (31.98 vs. 31.10 kg/m2 for the laparoscopic and robotic, respectively, p = 0.32). The laparoscopic group had a greater mean age compared to the robotic group (47.77 vs. 43.61 years, p = 0.04). There was no significant difference in sex and emergency surgery between the two groups. Fewer open conversions were found in the robotic than the laparoscopic group [2 (2.1%) vs. 17 (8.9%), p = 0.03]. In multiple logistic regression, robotic cholecystectomy with ICG also showed a lower risk of conversion compared to laparoscopic cholecystectomy, but the difference did not reach statistical significance (OR 0.42, 95% CI 0.11-1.65, p = 0.22). ICG fluorescent cholangiography during robotic cholecystectomy may contribute to proper identification of biliary structures and may reduce the rates of open conversion. The preliminary results of fewer open conversions are promising. Further studies with a large randomized prospective controlled study should be taken for further evaluation. PMID- 29181778 TI - Retzius space reconstruction following transperitoneal laparoscopic robot assisted radical prostatectomy: does it have any added value? AB - Retzius space sparing (RSS) during laparoscopic robot-assisted radical prostatectomy (RALP) has been offered as an approach that reduces perioperative complications and enables faster gaining of full urinary continence due to bladder anatomy preservation. Retro and transperitoneal techniques have been proposed, whereby RSS has been implemented. We sought to explore whether Retzius space reconstruction (RSR) following transperitoneal RALP will be an advantageous step as well. A prospective registry database of 102 consecutive transperitoneal RALP cases performed by a single surgeon was reviewed. The Retzius space had been opened by dissecting the bladder away from the anterior abdominal wall to the level of both internal rings. In the last 51 cases (RSR group), the peritoneal layer had been sutured back, thus repositioning the bladder back to the anterior abdominal wall and reconstructing the Retzius space. Perioperative factors were analyzed and compared between the two groups. Demographic and perioperative data did not differ between the two groups. RSR group demonstrated shorter length of stay (LOS) compared with the control group (p = 0.01), as well as faster urinary continence recovery (i.e., 0 pads) (p = 0.01). Moreover, lower numbers of Clavien Dindo class 3 complications and 12 mm port-site hernias (p = 0.03) were seen in the RSR group compared with the control group. RSR following transperitoneal RALP is a simple and efficient step that potentially reduces early and late post operative complications, shortens LOS and accelerates full urinary continence.

AB - Linking individuals in primary care settings with substance use disorders (SUDs) to SUD treatment has proven to be challenging, despite the widespread use of Screening, Brief Intervention, and Referral to Treatment (SBIRT). This paper reports findings from a pilot study that examined the efficacy of the Recovery Management Checkups intervention adapted for primary care settings (RMC-PC), for assertively linking and engaging patients from Federally Qualified Health Centers into SUD treatment. Findings showed that patients in the RMC-PC (n=92) had significantly higher rates of SUD treatment entry and received more days of SUD treatment compared with those who receive the usual SBIRT referral (n=50). Receipt of RMC-PC had both direct and indirect effects, partially mediated through days of SUD treatment, on reducing days of drug use at 6 months post intake. RMC-PC is a promising intervention to address the need for more assertive methods for linking patients in primary care to SUD treatment. PMID- 29181781 TI - Recognition of transposed melodies: Effects of pitch distance and harmonic distance. AB - People easily recognize a familiar melody in a previously unheard key, but they also retain some key-specific information. Does the recognition of a transposed melody depend on either pitch distance or harmonic distance from the initially learned instances? Previous research has shown a stronger effect of pitch closeness than of harmonic similarity, but did not directly test for an additional effect of the latter variable. In the present experiment, we familiarized participants with a simple eight-note melody in two different keys (C and D) and then tested their ability to discriminate the target melody from foils in other keys. The transpositions included were to the keys of C# (close in pitch height, but harmonically distant), G (more distant in pitch, but harmonically close), and F# (more distant in pitch and harmonically distant). Across participants, the transpositions to F# and G were either higher or lower than the initially trained melodies, so that their average pitch distances from C and D were equated. A signal detection theory analysis confirmed that discriminability (d') was better for targets and foils that were close in pitch distance to the studied exemplars. Harmonic similarity had no effect on discriminability, but it did affect response bias (c), in that harmonic similarity to the studied exemplars increased both hits and false alarms. Thus, both pitch distance and harmonic distance affect the recognition of transposed melodies, but with dissociable effects on discrimination and response bias.

AB - There is a need for physiologically relevant assay platforms to provide functionally relevant models of diabetes, to accelerate the discovery of new treatment options and boost developments in drug discovery. In this review, we compare several 3D-strategies that have been used to increase the functional relevance of ex vivo human primary pancreatic islets and developments into the generation of stem cell derived pancreatic beta-cells (beta-cells). Special attention will be given to recent approaches combining the use of extracellular matrix (ECM) scaffolds with pancreatic molecular memory, which can be used to improve yield and functionality of in vitro stem cell-derived pancreatic models. The ultimate goal is to develop scalable cell-based platforms for diabetes research and drug screening. This article will critically assess key aspects related to in vitro pancreatic 3D-ECM models and highlight the most promising approaches for future research.

AB - Is covert visuospatial attention-selective processing of information in the absence of eye movements-preserved in adults with attention-deficit/hyperactivity disorder (ADHD)? Previous findings are inconclusive due to inconsistent terminology and suboptimal methodology. To settle this question, we used well established spatial cueing protocols to investigate the perceptual effects of voluntary and involuntary attention on an orientation discrimination task for a group of adults with ADHD and their neurotypical age-matched and gender-matched controls. In both groups, voluntary attention significantly improved accuracy and decreased reaction times at the relevant location, but impaired accuracy and slowed reaction times at irrelevant locations, relative to a distributed attention condition. Likewise, involuntary attention improved accuracy and speeded responses. Critically, the magnitudes of all these orienting and reorienting attention effects were indistinguishable between groups. Thus, these counterintuitive findings indicate that spatial covert attention remains functionally intact in adults with ADHD. PMID- 29181783 TI - Capnocytophaga endodontalis sp. nov., Isolated from a Human Refractory Periapical Abscess. AB - A novel Gram-negative, capnophilic, fusiform bacterium, designated strain ChDC OS43T, was isolated from a human refractory periapical abscess in the left mandibular second molar and was characterized by polyphasic taxonomic analysis. The 16S rRNA gene sequence revealed that the strain belongs to the genus Capnocytophaga, as it showed sequence similarities to Capnocytophaga ochracea ATCC 27872T (96.30%) and C. sputigena ATCC 33612T (96.16%). The prevalent fatty acids of strain ChDC OS43T were isoC15:0 (57.54%), C16:0 (5.93%), C16:0 3OH (5.72%), and C18:1 cis 9 (4.41%). The complete genome of strain ChDC OS43T was 3,412,686 bp, and the G+C content was 38.2 mol%. The average nucleotide identity (ANI) value between strain ChDC OS43T and C. ochracea ATCC 27872T or C. sputigena ATCC 33612T was >92.01%. The genome-to-genome distance (GGD) value between strain ChDC OS43T and C. ochracea ATCC 27872T or C. sputigena ATCC 33612T was 32.0 and 45.7%, respectively. Based on the results of phenotypic, chemotaxonomic, and phylogenetic analysis, strain ChDC OS43T (= KCOM 1579T = KCTC 5562T = KCCM 42841T = JCM 32133T) should be classified as the type strain of a novel species of genus Capnocytophaga, for which the name Capnocytophaga endodontalis sp. nov. is proposed.

PMID- 29181785 TI - Multimodality imaging: Bird's eye view from The American College of Cardiology Annual Scientific Meeting 2017, Washington DC March 17 to 19, 2017. PMID- 29181786 TI - Early therapeutic effects of adaptive servo-ventilation on cardiac sympathetic nervous function in patients with heart failure evaluated using a combination of 11C-HED PET and 123I-MIBG SPECT. AB - RATIONALE: Adaptive servo-ventilation (ASV), a novel respiratory support therapy for sleep disorders, may improve cardiac function in heart failure (HF). However, the reasons that ASV improves cardiac function have not been fully studied especially in sympathetic nervous function (SNF). The purpose of the present study was to investigate the effects of ASV therapy on cardiac SNF in patients with HF. METHODS: We evaluated ASV therapeutic effects before and 6 months after ASV therapy in 9 HF patients [57.3 +/- 17.3 years old, left ventricular ejection fraction (LVEF) 36.1 +/- 16.7%]. We performed echocardiography, polysomnography, biomarkers, 11C-hydroxyephedrine (HED) PET as a presynaptic function marker and planar 123I-metaiodobenzylguanidine (MIBG) to evaluate washout rate. RESULTS: ASV therapy reduced apnea-hypopnea index (AHI) and improved plasma brain natriuretic peptide (BNP) concentration. In 123I-MIBG imaging, the early heart/mediastinum (H/M) ratio increased after ASV therapy (2.19 +/- 0.58 to 2.40 +/- 0.67; P = 0.045). Washout rate did not change (23.8 +/- 7.3% to 23.8 +/- 8.8%; P = 0.122). Global 11C-HED retention index (RI) improved from 0.068 +/- 0.033/s to 0.075 +/- 0.034/s (P = 0.029). CONCLUSIONS: ASV reduced AHI and improved BNP. ASV might initially improve presynaptic cardiac sympathetic nervous function in HF patients after 6 months of treatment. PMID- 29181787 TI - What Does 'Unpaid Consultant' Signify? A Survey of Euphemistic Language in Conflict of Interest Declarations. AB - BACKGROUND AND OBJECTIVE: Inadequate competing interest declarations present interpretive challenges for editors, reviewers, and readers. We systematically studied a common euphemism, 'unpaid consultant,' to determine its occurrence in declarations and its association with vested interests, authors, and journals. METHODS: We used Google Scholar, a search engine that routinely includes disclosures, to identify 1164 occurrences and 787 unique biomedical journal publications between 1994 and 2014 that included one or more authors declaring themselves as an "unpaid consultant." Changes over time were reckoned with absolute and relative yearly rates, the latter normalized by overall biomedical publication volumes. We further analyzed declarations according to author, consultancy recipient, and journal. RESULTS: We demonstrate increases in the use of "unpaid consultant" since 2004 and show that such uninformative declarations are overwhelmingly (801/865, 92.6%) associated with for-profit companies and other vested interests, most notably in the pharmaceutical, device, and biotech industries. CONCLUSIONS: Disclosing 'unpaid' relationships with for-profit companies typically signals but does not explain competing interests. Our findings challenge editors to respond to the increasing use of language that may conceal rather than illuminate conflicts of interest. PMID- 29181788 TI - Mortality Associated with Metformin Versus Sulfonylurea Initiation: A Cohort Study of Veterans with Diabetes and Chronic Kidney Disease. AB - BACKGROUND: For patients with type 2 diabetes and chronic kidney disease (CKD), high-quality evidence about the relative benefits and harms of oral glucose lowering drugs is limited. OBJECTIVE: To evaluate whether mortality risk differs after the initiation of monotherapy with either metformin or a sulfonylurea in Veterans with type 2 diabetes and CKD. DESIGN: Observational, national cohort study in the Veterans Health Administration (VHA). PARTICIPANTS: Veterans who received care from the VHA for at least 1 year prior to initiating monotherapy treatment for type 2 diabetes with either metformin or a sulfonylurea between 2004 and 2009. MAIN MEASURES: Metformin and sulfonylurea use was assessed from VHA electronic pharmacy records. The CKD-EPI equation was used to estimate glomerular filtration rate (eGFR). The outcome of death from January 1, 2004, through December 31, 2009, was assessed from VHA Vital Status files. KEY RESULTS: Among 175,296 new users of metformin or a sulfonylurea monotherapy, 5121 deaths were observed. In primary analyses adjusted for all measured potential confounding factors, metformin monotherapy was associated with a lower mortality hazard ratio (HR) compared with sulfonylurea monotherapy across all ranges of eGFR evaluated (HR ranging from 0.59 to 0.80). A secondary analysis of mortality risk differences favored metformin across all eGFR ranges; the greatest risk difference was observed in the eGFR category 30-44 mL/min/1.73m2 (12.1 fewer deaths/1000 person-years, 95% CI 5.2-19.0). CONCLUSIONS: Initiation of metformin versus a sulfonylurea among individuals with type 2 diabetes and CKD was associated with a substantial reduction in mortality, in terms of both relative and absolute risk reduction. The largest absolute risk reduction was observed among individuals with moderately-severely reduced eGFR (30-44 mL/min/1.73m2).

PMID- 29181790 TI - Improving Outcomes After Hospitalization: A Prospective Observational Multicenter Evaluation of Care Coordination Strategies for Reducing 30-Day Readmissions to Maryland Hospitals. AB - BACKGROUND: Patients frequently experience suboptimal transitions from the hospital to the community, which can increase the likelihood of readmission. It is not known which care coordination services can lead to improvements in readmission rates. OBJECTIVE: To evaluate the effects of two care coordination interventions on 30-day readmission rates. DESIGN: Prospective multicenter observational study of hospitalized patients eligible for two care coordination services between January 1, 2013, and October 31, 2015. Readmission rates were compared for patients who received each care coordination intervention versus those who did not using multivariable generalized estimating equation logistic regression models. PARTICIPANTS: A total of 25,628 patients hospitalized in medicine, neurosciences, or surgical sciences units. INTERVENTIONS: Patients discharged home and deemed to be at high risk for readmission were assigned a nurse Transition Guide (TG) for 30 days post-discharge. All other patients were assigned the Patient Access Line (PAL) intervention, which provided a post discharge phone call from a registered nurse. SETTING: Two large academic hospitals in Baltimore, MD. MAIN MEASURES: Thirty-day all-cause readmission to any Maryland hospital. KEY RESULTS: Among all patients, 14.2% (2409/16,993) of those referred for the PAL intervention and 22.8% (1973/8635) of those referred for the TG intervention were readmitted. PAL-referred patients who did not receive the intervention had an adjusted odds ratio (aOR) for readmission of 1.27 (95% confidence interval [95% CI] 1.12-1.44, p < 0.001) compared with patients who did. TG-referred patients who did not receive the TG intervention had an aOR of 1.83 (95% CI 1.60-2.10, p < 0.001) compared with patients who received the intervention. Younger age, male sex, having more comorbidities, and being discharged from a medicine unit were associated with not receiving an assigned intervention. These characteristics were also associated with higher readmission rates. CONCLUSIONS: PAL and TG care coordination interventions were associated with lower rates of 30-day readmission. Our findings underscore the importance of determining the appropriate intervention for the hardest-to-reach patients, who are also at the highest risk of being readmitted. PMID- 29181791 TI - Recruiting Rural Healthcare Providers Today: a Systematic Review of Training Program Success and Determinants of Geographic Choices. AB - BACKGROUND: Rural areas have historically struggled with shortages of healthcare providers; however, advanced communication technologies have transformed rural healthcare, and practice in underserved areas has been recognized as a policy priority. This systematic review aims to assess reasons for current providers' geographic choices and the success of training programs aimed at increasing rural provider recruitment. METHODS: This systematic review (PROSPERO: CRD42015025403) searched seven databases for published and gray literature on the current cohort of US rural healthcare practitioners (2005 to March 2017). Two reviewers independently screened citations for inclusion; one reviewer extracted data and assessed risk of bias, with a senior systematic reviewer checking the data; quality of evidence was assessed using the GRADE approach. RESULTS: Of 7276 screened citations, we identified 31 studies exploring reasons for geographic choices and 24 studies documenting the impact of training programs. Growing up in a rural community is a key determinant and is consistently associated with choosing rural practice. Most existing studies assess physicians, and only a few are based on multivariate analyses that take competing and potentially correlated predictors into account. The success rate of placing providers-in-training in rural practice after graduation, on average, is 44% (range 20-84%; N = 31 programs). We did not identify program characteristics that are consistently associated with program success. Data are primarily based on rural tracks for medical residents. DISCUSSION: The review provides insight into the relative importance of demographic characteristics and motivational factors in determining which providers should be targeted to maximize return on recruitment efforts. Existing programs exposing students to rural practice during their training are promising but require further refining. Public policy must include a specific focus on the trajectory of the healthcare workforce and must consider alternative models of healthcare delivery that promote a more diverse, interdisciplinary combination of providers. PMID- 29181792 TI - Medicaid Expansion, Mental Health, and Access to Care among Childless Adults with and without Chronic Conditions. AB - BACKGROUND: While the Affordable Care Act's (ACA) Medicaid expansion has increased insurance coverage, its effects on health outcomes have been mixed. This may be because previous research did not disaggregate mental and physical health or target populations most likely to benefit. OBJECTIVE: To examine the association between Medicaid expansion and changes in mental health, physical health, and access to care among low-income childless adults with and without chronic conditions. DESIGN: We used a difference-in-differences analytical framework to assess differential changes in self-reported health outcomes and access to care. We stratified our analyses by chronic condition status. PARTICIPANTS: Childless adults, aged 18-64, with incomes below 138% of the federal poverty level in expansion (n = 69,620) and non-expansion states (n = 57,628). INTERVENTION: Active Medicaid expansion in state of residence. MAIN MEASURES: Self-reported general health; total days in past month with poor health, poor mental health, poor physical health, or health-related activity restrictions; disability; depression; insurance coverage; cost-related barriers; annual check-up; and personal doctor. KEY RESULTS: Medicaid expansion was associated with reductions in poor health days (-1.2 days [95% CI, -1.6,-0.7]) and days limited by poor health (-0.94 days [95% CI, -1.4,-0.43]), but only among adults with chronic conditions. Trends in general health measures appear to be driven by fewer poor mental health days (-1.1 days [95% CI, -1.6,-0.6]). Expansion was also associated with a reduction in depression diagnoses (-3.4 percentage points [95% CI, -6.1,-0.01]) among adults with chronic conditions. Expansion was associated with improvements in access to care for all adults. CONCLUSIONS: Medicaid expansion was associated with substantial improvements in mental health and access to care among low-income adults with chronic conditions. These positive trends are likely to be reversed if Medicaid expansion is repealed. PMID- 29181793 TI - In reply: Eye taping and chlorhexidine exposure: caution when interpreting scarce evidence.

PMID- 29181795 TI - Comparison of 3D Echocardiogram-Derived 3D Printed Valve Models to Molded Models for Simulated Repair of Pediatric Atrioventricular Valves. AB - Mastering the technical skills required to perform pediatric cardiac valve surgery is challenging in part due to limited opportunity for practice. Transformation of 3D echocardiographic (echo) images of congenitally abnormal heart valves to realistic physical models could allow patient-specific simulation of surgical valve repair. We compared materials, processes, and costs for 3D printing and molding of patient-specific models for visualization and surgical simulation of congenitally abnormal heart valves. Pediatric atrioventricular valves (mitral, tricuspid, and common atrioventricular valve) were modeled from transthoracic 3D echo images using semi-automated methods implemented as custom modules in 3D Slicer. Valve models were then both 3D printed in soft materials and molded in silicone using 3D printed "negative" molds. Using pre-defined assessment criteria, valve models were evaluated by congenital cardiac surgeons to determine suitability for simulation. Surgeon assessment indicated that the molded valves had superior material properties for the purposes of simulation compared to directly printed valves (p < 0.01). Patient-specific, 3D echo-derived molded valves are a step toward realistic simulation of complex valve repairs but require more time and labor to create than directly printed models. Patient specific simulation of valve repair in children using such models may be useful for surgical training and simulation of complex congenital cases. PMID- 29181796 TI - Risk Factors for an Elevated Ventricular End-Diastolic Pressure Prior to the Fontan Operation. AB - Systemic ventricular end-diastolic pressure (SVEDP) is an important determinant of pulmonary artery pressure in those with a Fontan circulation. Predictors of an elevated SVEDP have been incompletely identified in this population. All who underwent the Fontan operation at our center between 1/2009 and 12/2013 were retrospectively identified. SVEDP at the pre-Fontan catheterization and other patient variables were extracted. We identified 61 patients. Pre-Fontan SVEDP was positively associated with systemic ventricular systolic pressure (beta = 0.4, p = 0.004), aortic systolic pressure (beta = 0.3, p = 0.007), aortic mean pressure (beta = 0.3, p = 0.02), and decreased ventricular systolic function (p = 0.03). Compared to those with pre-Fontan SVEDP <= 7 mmHg, patients with SVEDP > 7 mmHg had higher average ventricular systolic pressure (85.0 +/- 7.5 vs. 78.7 +/- 8.3 mmHg, p = 0.003), higher average descending aorta mean pressure (62.4 +/- 4.9 vs. 58.6 +/- 8.1 mmHg, p = 0.03), and a higher incidence of decreased ventricular systolic function (36 vs. 15%, p = 0.07). For those with a systemic right ventricle, the SVEDP decreased significantly from the pre-Stage 2 to pre-Fontan measurements (8.7 +/- 2.6 vs. 7.3 +/- 2.0 mmHg, p = 0.02), but not for those with a systemic left ventricle (7.8 +/- 2.0 vs. 7.2 +/- 1.8 mmHg, p = 0.3). At pre Fontan catheterization, decreased ventricular systolic function and markers of systemic afterload were positively associated with the SVEDP. SVEDP decreased significantly after Stage 2 for those with a systemic right ventricle, but not for those with a systemic left ventricle; the systemic right ventricle may be particularly vulnerable to pre-Stage 2 volume loading. PMID- 29181797 TI - Incidence of Persistent Left Superior Vena Cava in the Normal Population and in Patients with Congenital Heart Diseases Detected Using Echocardiography. AB - Reports on the incidence of persistent left superior vena cava (PLSVC) in the normal population are limited to studies involving pacemaker implantation candidates and cadavers. The incidence in patients with congenital heart diseases (CHDs) is estimated to be higher than that in the normal population; however, the details are unclear. To investigate the incidence of PLSVC in the normal population and in patients with CHDs, subjects were examined prospectively using echocardiography. Normal subjects consisted of 2841 successive neonates without intra-cardiac or congenital anomalies born in Gifu Prefectural General Medical Center. Additionally, 1920 patients with CHDs were evaluated. The incidence of PLSVC in normal neonates was 0.21% (95% confidence interval 0.042-0.38%). A high incidence (more than 7.0 times the incidence in normal subjects) was observed in all CHD patients. The high incidence group included coarctation of the aorta (CoA) (23.7%) and double outlet right ventricle (DORV) patients (24.6%). The second group consisted of CHD patients with ventricular septal defect (VSD), with an incidence ranging from 5.1 to 6.1%. The low incidence group comprised patients with other CHDs, with an incidence between 1.5 and 3.1%. The incidence of PLSVC in trisomy 21 and atrial septal defect patients was significantly higher than that in normal neonates. The incidence of PLSVC in the normal population and in patients with CHDs was systematically evaluated for the first time. The incidence in CHD patients appeared to be positively influenced by the type of CHD, particularly by DORV, CoA, and VSD. PMID- 29181798 TI - Low Peak dP/dt in the Descending Aorta in Patients After Successful Aortic Arch Repair. AB - One of the most important problems in patients with aortic coarctation or interruption of the aortic arch after successful aortic arch repair is developing cardiovascular disease in the future. It has been reported that the repaired site is stiff and generates a new pressure wave reflection, which could lead to cardiovascular disease. The purpose of this study was to clarify the influence of the repaired portion's stiffness on the pressure waveform in patients. Fifteen patients (age: 7.4 +/- 3.2 years) who had successful aortic arch repair were enrolled. Their peak dP/dt in the ascending aorta (AAo) and the descending aorta (DAo) were compared with those of age-matched controls with a normal aortic arch. The ascending and descending aortic systolic blood pressures in aortic arch repair patients were higher than those in age-matched controls (AAo: 103.1 +/- 13.3 vs. 91.9 +/- 9.2 mmHg, p = 0.012 and DAo: 108.7 +/- 16.4 vs. 96.5 +/- 9.9 mmHg, p = 0.020). Although no difference existed in the peak dP/dt in the AAo between the aortic arch repair patients and the controls (572.1 +/- 100.1 vs. 543.3 +/- 110.2 mmHg/s, p = 0.460), the peak dP/dt in the DAo in the aortic arch repair patients was significantly lower than that in the controls (489.3 +/- 75.2 vs. 579.4 +/- 106.0 mmHg/s, p = 0.013). The peak dP/dt in the DAo in aortic arch repair patients is low. The stiff repaired site may attenuate pulsation. PMID- 29181799 TI - Modeling blood flow around a thrombus using a hybrid particle-continuum approach. AB - A hybrid, multiscale, particle-continuum numerical method is developed for resolving the interaction of a realistic thrombus geometry with unsteady hemodynamics typically occurring within large arteries. The method is based on a discrete particle/element description of the thrombus, coupled to blood flow using a fictitious domain finite element method. The efficacy of the discrete element approach in representing thrombi with arbitrary aggregate morphology and microstructure is demonstrated. The various features of the method are illustrated using a series of numerical experiments with a model system consisting of an occlusion embedded in a channel. The results from these numerical experiments establish that this approach can resolve the complex macroscale flow structures emanating from unsteady hemodynamics interacting with a thrombus. Simultaneously, it can also resolve micromechanical features, and microscale intra-thrombus flow and perfusion. Using a staggering algorithm, the method can further capture hemodynamics around time-varying thrombus manifolds. This is established using a numerical simulation of lysis of an idealized clot. The hybrid particle-continuum description of thrombus-hemodynamics interaction mechanics, and the unified treatment of macroscale as well as microscale flow and transport, renders significant advantages to the proposed method in enabling further investigations of physiological interest in thrombosis within patient specific settings. PMID- 29181800 TI - Inoculation density is affecting growth conditions of Listeria monocytogenes on fresh cut lettuce. AB - Listeria monocytogenes is a particular risk for the ready-to-eat food sector because of its ability to grow in various environmental conditions. In the literature, growth and survival of L. monocytogenes on food is tested using inoculation densities ranging from less than 102 to over 105 CFU g-1. Inoculation densities on food have been rarely tested as a factor for growth. In this study, inoculation densities from 102 to 105 of L. monocytogenes were tested on iceberg lettuce (Lactuca sativa) in modified atmospheres and air in model packages at 4 and 8 degrees C to identify any potential inoculation density effects. On days 0, 2, 5 and 7, L. monocytogenes was extracted from the lettuce surface and enumerated via selective media. The resulting growth curves identified a significant inoculation density effect at 4 and 8 degrees C with significantly higher amounts of growth (1-2 logs) when lettuce was inoculated at 102 CFU g-1 as opposed to 104 and 105 CFU g-1. In contrast, the use of different atmospheres had limited influence on growth of L. monocytogenes. In conclusion, greater emphasis on inoculation density of L. monocytogenes should be taken in inoculation experiments when confirmation of growth or the efficacies of growth inhibiting treatments are tested on ready-to-eat food such as lettuce. PMID- 29181801 TI - Cross-Cultural Validation of the Korean Version of the Chalder Fatigue Scale. AB - PURPOSE: University students are vulnerable to fatigue. If not adequately dealt with, fatigue might develop into various health problems and negatively affect quality of life (QOL). The present study examined psychometric properties of the Korean version of the Chalder Fatigue Scale (K-CFQ) in university students. METHOD: Data were obtained from two samples of undergraduate students in Korea. The first dataset (N = 557) was collected in a cross-sectional survey in 2015 and the second dataset (N = 338) from a longitudinal survey with three time points over a semester period in 2016. Participants completed measures of fatigue, QOL, depression, anxiety, and sleep quality. RESULTS: Three-factor model (physical fatigue, low energy, and mental fatigue) rather than the original two-factor model (physical and mental fatigue) provided a better goodness of fit indices to the data. Internal consistency of the K-CFQ was satisfactory, with Cronbach's alpha value of 0.88 for the total scale and those of subscales ranging from 0.73 to 0.87. Its convergent validity was supported by its significant association with anxiety, depression, sleep quality, and QOL. Significant association between T1 K-CFQ with physical QOL at T2 and T3 supported its predictive validity. Its known-group validity was proven with higher K-CFQ scores observed in the participants with depression and those with poor sleep quality. CONCLUSIONS: Current results suggest that K-CFQ is a valid and reliable measure of fatigue, and a better model fit of the three-factor structure of the K-CFQ implies potential cross-cultural differences in the dimensionality of fatigue.

AB - According to the World Health Organization (WHO), using antibiotics as growth promoters for livestock-particularly swine-is the principal cause of antibiotic resistance. It is therefore clear that finding an alternative to antibiotics becomes an emergency. Hundreds of recent studies have appointed probiotics as potential candidates to replace or to be used in combination with antibiotics. However, bringing probiotics alive to the colon-their site of action-remains a big challenge because of different physiological barriers encountered in proximal gastrointestinal tract (GIT) such as acidic pH and bile salts that may affect the viability of probiotic cultures. To overcome this problem, in previous studies, we developed and characterize a synbiotic formula consisting of beads of a mixture of alginate and inulin. Three potential probiotics strains namely Pediococcus acidilactici UL5 (UL5), Lactobacillus reuteri (LR), and Lactobacillus salivarius (LS) were encapsulated to study their release and the behavior of this synbiotic formula throughout the GIT using in vitro models. The survival and the release of bacteria from beads were studied by specific PMA-qPCR counting. The microscopic aspects of the beads were studied using scanning electron microscopy (SEM). Moreover, the microbial dynamics inside beads were studied by fluorescence microscopy using the live/dead test. Our results have shown that the beads containing 5% inulin were the most stable in the stomach and throughout the small intestine. However, beads were completely degraded in approximately 3 h of incubation in the fermented medium that mimic the colon. These results were confirmed by SEM and fluorescence microscopy images. Therefore, it can be stated that the AI5 formulation well protected the bacteria in the upper part of the digestive tract and allowed their controlled release in the colon. PMID- 29181803 TI - Functional Characterization of Probiotic Potential of Novel Pigmented Bacterial Strains for Aquaculture Applications. AB - The bioprospecting proficient of novel pigmented probiotic strains with respect to aquaculture industry was unexplored hitherto. In this study, we investigated the probiotic potential of novel pigmented bacterial strains isolated from the indigenous soil sediments in their vicinal habitats, which were screened for their antimicrobial activity against aquatic pathogens using agar well diffusion assay. The strains namely Exiguobacterium acetylicum (S01), Aeromonas veronii (V03), and Chryseobacterium joostei (V04) were phenotypically identified and confirmed by 16S rRNA gene sequence analysis. Further characterization revealed that strains S01 and V03 survive relatively in lower pH and higher bile salt concentrations and possess good adherence ability and broad-spectrum antibiotic susceptibility. The isolate S01 exhibited the higher adhesion ability to hydrocarbons (82%) and mannose-specific adhesion (msa) gene expression. Additionally, the probiotic effects were evaluated in Artemia nauplii fed with algae supplemented with S01, V03, and V04 strains (2.7 * 107 cfu/mL) for 3 days under axenic environment. We observed a significant increase (p < 0.05) in the survival rate of Artemia nauplii treated with S01 (83 +/- 5%) and V03 (55 +/- 5%), whereas the survival rate was only 30 +/- 0% in the untreated group. Moreover, the individual length (IL) was increased in treated group S01 (156.7 +/ 2.2 MUm), V03 (146.1 +/- 3.4 MUm), and V04 (134.4 +/- 2.5 MUm) compared with untreated group (116.0 +/- 4.8 MUm). Our results revealed that E. acetylicum S01 exhibits desirable functional probiotic attributes compared to A. veronii and C. joostei and it would be a promising probiotic strain, which can be efficiently used in the aquaculture applications. PMID- 29181804 TI - Vigorous intensity aerobic interval exercise in bladder cancer patients prior to radical cystectomy: a feasibility randomised controlled trial. AB - PURPOSE: Strategies to improve pre-operative cardiopulmonary fitness could positively impact recovery after surgery. This study investigated the feasibility of vigorous intensity aerobic interval exercise in bladder cancer patients prior to radical cystectomy (RC). METHODS: A total of 60 patients were randomised (1:1) to exercise or control following a cardiopulmonary exercise test (CPET). The exercise group was offered twice-weekly pre-operative supervised vigorous intensity aerobic interval exercise in addition to standard treatment. The controls received standard treatment only. A repeat CPET was undertaken before surgery and post-operative recovery outcomes were recorded. RESULTS: Over half of the 112 eligible patients approached in the clinic were recruited to the study (53.5%), with recruited patients attending a median of 8 (range 1-10) exercise sessions over a pre-operative period of 3-6 weeks. Improvements in peak values of oxygen pulse (P = 0.001), minute ventilation (P = 0.002) and power output (P < 0.001) were observed at the follow-up CPET in the exercise group versus controls and there were no adverse events. Although this feasibility study was not powered to detect changes in post-operative recovery outcomes, there were marginal (non significant) differences in favour of the exercise group in post-operative Clavien-Dindo score and need for high dependency unit inotropic support. CONCLUSIONS: Bladder cancer patients respond well to pre-surgical aerobic interval exercise, and the improvements in cardiopulmonary fitness variables could have important implications for post-operative recuperation after RC. These findings provide a strong foundation for an adequately powered randomised controlled trial. PMID- 29181805 TI - Understanding Power Anomalies in Mediation Analysis. AB - Previous studies have found some puzzling power anomalies related to testing the indirect effect of a mediator. The power for the indirect effect stagnates and even declines as the size of the indirect effect increases. Furthermore, the power for the indirect effect can be much higher than the power for the total effect in a model where there is no direct effect and therefore the indirect effect is of the same magnitude as the total effect. In the presence of direct effect, the power for the indirect effect is often much higher than the power for the direct effect even when these two effects are of the same magnitude. In this study, the limiting distributions of related statistics and their non centralities are derived. Computer simulations are conducted to demonstrate their validity. These theoretical results are used to explain the observed anomalies. PMID- 29181806 TI - "Coil mainly" policy in management of intracranial ACoA aneurysms: single-centre experience with the systematic review of literature and meta-analysis. AB - Endovascular techniques are still expanding in their capability by introducing novel technologies. Nevertheless, anterior communicating artery (ACoA) remains the region with high propensity for aneurysm (AN) re-growth after endovascular intervention. The purpose of this study is to highlight the ongoing importance for microsurgical treatment. The authors conducted a single-institution retrospective study of ACoA AN treatment between January 2000 and December 2016 maintaining "coil mainly" policy. The results are supplied with a systematic review of the literature. A total of n = 398 ACoA ANs were treated in n = 398 consecutive patients (207 females, 191 males). Microsurgical treatment was performed for 79 AN patients (54 ruptured, 25 unruptured), and 319 AN patients (250 ruptured, 69 unruptured) underwent coiling procedure. Treatment-related morbidity and mortality (MM) for unruptured ANs was 0% in the microsurgical and 1.5% in the endovascular group (p = 1.000). The percentage of patients with none or minor permanent deficits after subarachnoid hemorrhage was 74% in the microsurgical and 70% in the endovascular group (p = 0.693). The re-treatment rate was 3.8% in microsurgical group and 9.2% in endovascular group (p = 0.883). A literature review identified 39 studies concerning ACoA AN treatment. Clinical results of both modalities were comparable, with microsurgery being superior regarding radiological outcomes. This study demonstrates that both treatment techniques bring comparable clinical benefit to the patient. Microsurgery seemed superior regarding radiological outcomes. The decision about the treatment strategy should be made by a multi-disciplinary team consisting of specialists from both teams, bearing in mind the higher occlusion rate and longevity of the surgical treatment. PMID- 29181809 TI - [Trends in incidence of lung cancer according to histological subtype among men and women in Germany : Analysis of cancer registry data with the application of multiple imputation techniques]. AB - BACKGROUND: Lung cancer can be described by histological subtype, of which small cell, squamous cell and adenocarcinoma are the most common. International data show that adenocarcinoma is becoming the dominant histological subtype of lung cancer although the relative risk due to smoking has been found to be smaller than that for other histological subtypes. OBJECTIVE: The aim of the analysis was to describe the time trends in incidence of lung cancer among women and men in Germany according to histological subtype. MATERIALS AND METHODS: All lung cancer cases (ICD-10 C33-C34) newly diagnosed between 2003 and 2012 and collected by the epidemiologic cancer registries of the German federal states with average completeness of registration of at least 90% were considered and grouped into histologic subtypes. If data on tumor histology were not microscopically verified or unspecific, multiple imputation techniques were applied to estimate the histologic subtype. RESULTS: Among women age-standardized lung cancer rates increased considerably between 2003 and 2012 (annual percent change APC = 2.7%), mostly driven by a rising adenocarcinoma incidence (APC = 4.7%). Among men overall lung cancer rates decreased during the same time (APC = -1.7%). Still, a slight increase in adenocarcinoma incidence was also observed in men (APC = 1.0%). CONCLUSION: The rising incidence of adenocarcinoma of the lung is alarming. The cancer registry data do not allow risk factor analysis. In the international discussion, the introduction of filter cigarettes as well as the changing composition of cigarettes has been hypothesized as being responsible. Further epidemiologic studies are strongly needed. PMID- 29181808 TI - Socially Constructed Hierarchies of Impairments: The Case of Australian and Irish Workers' Access to Compensation for Injuries. AB - OBJECTIVES: Socially constructed hierarchies of impairment complicate the general disadvantage experienced by workers with disabilities. Workers with a range of abilities categorized as a "disability" are likely to experience less favourable treatment at work and have their rights to work discounted by laws and institutions, as compared to workers without disabilities. Value judgments in workplace culture and local law mean that the extent of disadvantage experienced by workers with disabilities additionally will depend upon the type of impairment they have. Rather than focusing upon the extent and severity of the impairment and how society turns an impairment into a recognized disability, this article aims to critically analyse the social hierarchy of physical versus mental impairment. METHODS: Using legal doctrinal research methods, this paper analysis how Australian and Irish workers' compensation and negligence laws regard workers with mental injuries and impairments as less deserving of compensation and protection than like workers who have physical and sensory injuries or impairments. RESULTS: This research finds that workers who acquire and manifest mental injuries and impairments at work are less able to obtain compensation and protection than workers who have developed physical and sensory injuries of equal or lesser severity. Organizational cultures and governmental laws and policies that treat workers less favourably because they have mental injuries and impairments perpetuates unfair and artificial hierarchies of disability attributes. CONCLUSIONS: We conclude that these "sanist" attitudes undermine equal access to compensation for workplace injury as prohibited by the United Nations Convention on the Rights of Persons with Disabilities. PMID- 29181807 TI - Pharmacogenomic Biomarkers for Improved Drug Therapy-Recent Progress and Future Developments. AB - Much of the inter-individual variability in drug efficacy and risk of adverse reactions is due to polymorphisms in genes encoding proteins involved in drug pharmacokinetics and pharmacodynamics or immunological responses. Pharmacogenetic research has identified a multitude of gene-drug response associations, which have resulted in genetically guided treatment and dosing decisions to yield a higher success rate of pharmacological treatment. The rapid technological developments for genetic analyses reveal that the number of genetic variants with importance for drug action is much higher than previously thought and that a true personalized prediction of drug response requires attention to millions of rare mutations. Here, we review the evolutionary background of genetic polymorphisms in drug-metabolizing enzymes, provide some important examples of current use of pharmacogenomic biomarkers, and give an update of germline and somatic genome biomarkers that are in use in drug development and clinical practice. We also discuss the current technology development with emphasis on complex genetic loci, review current initiatives for validation of pharmacogenomic biomarkers, and present scenarios for the future taking rare genetic variants into account for a true personalized genetically guided drug prescription. We conclude that pharmacogenomic information for patient stratification is of value to tailor optimized treatment regimens particularly in oncology. However, the routine use of pharmacogenomic biomarkers in clinical practice in other therapeutic areas is currently sparse and the prospects of its future implementation are being scrutinized by different international consortia. PMID- 29181811 TI - Temperature Dependence of Arn+ Cluster Backscattering from Polymer Surfaces: a New Method to Determine the Surface Glass Transition Temperature. AB - In this work, time-of-flight secondary ion mass spectrometry (ToF-SIMS) was used to study the intensity variations of the backscattered Arn+ clusters as a function of temperature for several amorphous polymer surfaces (polyolefins, polystyrene, and polymethyl methacrylate). For all these investigated polymers, our results show a transition of the ratio Ar2+/(Ar2+ + Ar3+) when the temperature is scanned from -120 degrees C to +125 degrees C (the exact limits depend on the studied polymer). This transition generally spans over a few tens of degrees and the temperature of the inflection point of each curve is always lower than the bulk glass transition temperature (Tg) reported for the considered polymer. Due to the surface sensitivity of the cluster backscattering process (several nanometers), the presented analysis could provide a new method to specifically evaluate a surface transition temperature of polymers, with the same lateral resolution as the gas cluster beam.

AB - BACKGROUND: Zika virus (ZIKV) is a neurotropic and neurotoxic RNA Flavivirus prompt to cause severe fetal brain dysmorphisms during pregnancy, a period of rapid and critical central nervous system development. A wide range of clinico radiological findings of congenital ZIKV infections were reported in the literature, such as microcephaly, overlapping sutures, cortical migrational and corpus callosum abnormalities, intracranial calcifications, ventriculomegaly, brain stem and cerebellar malformations, spinal cord involvement, and joint contractures. ZIKV is also related to other severe neurological manifestations in grown-up individuals such as Guillain-Barre syndrome and encephalomyelitis. PURPOSE: Our purpose is to review the radiological central nervous system abnormalities of congenital ZIKV infection syndrome on different imaging modalities. PMID- 29181812 TI - MALDI-TOF-MS with PLS Modeling Enables Strain Typing of the Bacterial Plant Pathogen Xanthomonas axonopodis. AB - Matrix-assisted desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) is a fast and effective tool for microbial species identification. However, current approaches are limited to species-level identification even when genetic differences are known. Here, we present a novel workflow that applies the statistical method of partial least squares discriminant analysis (PLS-DA) to MALDI-TOF-MS protein fingerprint data of Xanthomonas axonopodis, an important bacterial plant pathogen of fruit and vegetable crops. Mass spectra of 32 X. axonopodis strains were used to create a mass spectral library and PLS-DA was employed to model the closely related strains. A robust workflow was designed to optimize the PLS-DA model by assessing the model performance over a range of signal-to-noise ratios (s/n) and mass filter (MF) thresholds. The optimized parameters were observed to be s/n = 3 and MF = 0.7. The model correctly classified 83% of spectra withheld from the model as a test set. A new decision rule was developed, termed the rolled-up Maximum Decision Rule (ruMDR), and this method improved identification rates to 92%. These results demonstrate that MALDI TOF-MS protein fingerprints of bacterial isolates can be utilized to enable identification at the strain level. Furthermore, the open-source framework of this workflow allows for broad implementation across various instrument platforms as well as integration with alternative modeling and classification algorithms. Graphical abstract ?. PMID- 29181813 TI - Probe-Substrate Distance Control in Desorption Electrospray Ionization. AB - We introduce probe-substrate distance (Dps)-control to desorption electrospray ionization (DESI) and report a systematic investigation of key experimental parameters. Examination of voltage, flow rate, and nebulizing gas pressure suggests as Dps decreases, the distance-dependent spray current increases, until a critical point. At the critical point the relationship inverts, and the spray current decreases as the probe moves closer to the surface due to constriction of solution flow by the nebulizing gas. Dps control was used to explore the use of spray current as a signal for feedback positioning, while mass spectrometry imaging was performed simultaneously. Further development of this technique is expected to find application in study of structure-function relationships for clinical diagnostics, biological investigation, and materials characterization. Graphical abstract ?. PMID- 29181814 TI - A high working memory load prior to memory retrieval reduces craving in non treatment seeking problem drinkers. AB - BACKGROUND: Reconsolidation-based interventions have been suggested to be a promising treatment strategy for substance use disorders. In this study, we aimed to investigate the effectiveness of a working memory intervention to interfere with the reconsolidation of alcohol-related memories in a sample of non-treatment seeking heavy drinkers. METHODS: Participants were randomized to one of the two conditions that underwent a 3-day intervention: in the experimental condition, a 30-min working memory training was performed immediately after a 15-min memory retrieval session (i.e., within the memory reconsolidation time-window), whereas in the control condition, the working memory training was performed prior to a memory retrieval session. RESULTS: In contrast to our original hypothesis, a high working memory load after memory retrieval did not interfere with the reconsolidation of those memories while a high working memory load prior to memory retrieval (the original control condition) strongly reduced retrieval induced craving and craving for alcohol at follow-up. CONCLUSION: Whereas the neurocognitive mechanism behind this effect needs to be further investigated, the current findings suggest that, if replicated, working memory training prior to addiction-related memory retrieval has the potential to become an effective (adjunctive) intervention in the treatment of substance use disorders. PMID- 29181815 TI - Effects of adolescent alcohol exposure on stress-induced reward deficits, brain CRF, monoamines and glutamate in adult rats. AB - BACKGROUND: Adolescent alcohol exposure may increase depression vulnerability in adulthood by increasing the anhedonic response to stress. METHODS: Male Wistar rats (postnatal days 28-53) were exposed to binge-like adolescent intermittent ethanol (AIE) or water. In adulthood, rats were exposed to social defeat, consisting of daily confrontations with an aggressive conspecific, followed by testing of brain reward function in a discrete-trial current-intensity intracranial self-stimulation procedure for 10 consecutive days. Neurochemistry and corticotropin-releasing factor (CRF) and CRF receptor 1 (CRFR1) mRNA levels were assessed in corticolimbic brain areas on day 11 of social defeat stress. RESULTS: Social defeat elevated reward thresholds in both AIE- and water-exposed rats indicating stress-induced anhedonia. However, AIE-exposed rats were more likely to show threshold elevations after repeated stress compared to water exposed rats. AIE exposure decreased CRF mRNA levels in the nucleus accumbens and increased CRFR1 mRNA levels in the prefrontal cortex, while stress increased CRF mRNA levels in the central amygdala. In the caudate putamen, AIE exposure decreased dopamine turnover, while stress increased glutamate and serotonin metabolism and turnover. CONCLUSIONS: These results demonstrate increased risk of repeated stress-induced anhedonia after AIE exposure, an effect that may be due to alterations in brain CRF and dopamine systems. These results suggest that the increased rates of depression reported in people with a history of adolescent alcohol exposure may be related to alterations in brain reward and stress systems that may contribute to increased stress-induced anhedonia. PMID- 29181818 TI - Correction for Partial Volume Effect Is a Must, Not a Luxury, to Fully Exploit the Potential of Quantitative PET Imaging in Clinical Oncology. AB - The partial volume effect (PVE) is considered as one of the major degrading factors impacting image quality and hampering the accuracy of quantitative PET imaging in clinical oncology. This effect is the consequence of the limited spatial resolution of whole-body PET scanners, which results in blurring of the generated images by the scanner's response function. A number of strategies have been devised to deal with partial volume effect. However, the lack of consensus on the clinical relevance of partial volume correction and the most appropriate technique to be used in the context of clinical oncology limited their application in clinical setting. This issue is debated in this commentary. PMID- 29181816 TI - Nicotine-induced activation of caudate and anterior cingulate cortex in response to errors in schizophrenia. AB - BACKGROUND: Nicotine improves attention and processing speed in individuals with schizophrenia. Few studies have investigated the effects of nicotine on cognitive control. Prior functional magnetic resonance imaging (fMRI) research demonstrates blunted activation of dorsal anterior cingulate cortex (dACC) and rostral anterior cingulate cortex (rACC) in response to error and decreased post-error slowing in schizophrenia. METHODS: Participants with schizophrenia (n = 13) and healthy controls (n = 12) participated in a randomized, placebo-controlled, crossover study of the effects of transdermal nicotine on cognitive control. For each drug condition, participants underwent fMRI while performing the stop signal task where participants attempt to inhibit prepotent responses to "go (motor activation)" signals when an occasional "stop (motor inhibition)" signal appears. Error processing was evaluated by comparing "stop error" trials (failed response inhibition) to "go" trials. Resting-state fMRI data were collected prior to the task. RESULTS: Participants with schizophrenia had increased nicotine-induced activation of right caudate in response to errors compared to controls (DRUG * GROUP effect: p corrected < 0.05). Both groups had significant nicotine-induced activation of dACC and rACC in response to errors. Using right caudate activation to errors as a seed for resting-state functional connectivity analysis, relative to controls, participants with schizophrenia had significantly decreased connectivity between the right caudate and dACC/bilateral dorsolateral prefrontal cortices. CONCLUSIONS: In sum, we replicated prior findings of decreased post error slowing in schizophrenia and found that nicotine was associated with more adaptive (i.e., increased) post-error reaction time (RT). This proof-of-concept pilot study suggests a role for nicotinic agents in targeting cognitive control deficits in schizophrenia. PMID- 29181817 TI - Health economic evaluation of rivaroxaban in elective cardioversion of atrial fibrillation. AB - BACKGROUND: Electrical cardioversion (ECV) is a procedure in which a direct current electric shock is used to quickly and effectively restore the normal sinus rhythm. Appropriate anticoagulation reduces the risk of embolic events during and after ECV. The aim of this study was to estimate the cost effectiveness of rivaroxaban compared with vitamin K oral antagonists (VKAs) in patients with atrial fibrillation undergoing elective ECV in the Netherlands. METHODS AND RESULTS: A static transmission model over a 1-year time horizon was developed to compare rivaroxaban with VKAs in terms of clinical outcomes, health effects (quality-adjusted life years; QALYs), and costs. Cost-effectiveness was assessed from a societal and health care payer perspective at a willingness-to pay level of ?20,000 per QALY gained. The use of rivaroxaban as an anticoagulant in patients with atrial fibrillation scheduled for ECV would lead to a health gain of 0.23 QALYs per patient and would cost ?1.83 per patient from the societal perspective, resulting in an incremental cost-effectiveness ratio of ?7.92 per QALY gained. The probability of rivaroxaban being cost-saving compared with VKAs was 49.6% from this perspective. From the health care payer perspective, the incremental cost would be ?509 per patient with a health gain of 0.23 QALYs per patient, resulting in an incremental cost-effectiveness ratio of ?2198 per QALY gained. CONCLUSIONS: The use of rivaroxaban in elective ECV is a cost-effective alternative to the use of VKAs. Rivaroxaban has a 50% probability of being cost saving compared with VKAs and would increase a patient's quality of life when non health care costs such as productivity loss and informal care costs are taken into account.

PMID- 29181820 TI - Role of Trace Elements, Oxidative Stress and Immune System: a Triad in Premature Ovarian Failure. AB - The risk of premature ovarian failure (POF) increases in association with alteration in immunological parameters and oxidative stress (OS). Adequate intake of trace elements is required for antioxidant property and immune defense mechanism. The aim of this study was to explore the involvement of trace elements, OS, and immunological parameters in POF. This was a cross-sectional, case-control study, involving 65 participants divided into the POF (n = 35) and control (n = 30) groups. Serum levels of Se, Zn, and Cu were determined along with hormonal, OS, and immunological markers. POF group had significantly lower levels of Zn, Cu, Se, and Zn:Cu ratio. However, Se:Cu ratio was not significant between the groups. FSH and LH levels were negatively correlated with Zn and Cu levels and positively correlated with Se levels. Estrogen levels were negatively correlated with all the studied trace elements. Inter-element association between Zn and Se was significant in POF (r = - 0.39, p = 0.02) compared to control group (r = - 0.078, p = 0.65). In all the POF patients, SOD and GPx activities were significantly (p < 0.05) lower and MDA level was higher (p > 0.05) than control group. B cell marker CD19 was significantly (p < 0.0001) high in POF group. There are involvement of trace elements in hormonal regulation and antioxidant defense mechanism, which once gets altered leads to high ROS generation and affect functions of the immune system. Exaggereative immune system causing higher expression of B cell associated markers (CD19) leading to autoimmune condition in POF. PMID- 29181821 TI - Combination Effects of Organic and Inorganic Chromium on Production Performance, Reproductive Response, Immune Status, and Maternal Antibody Transmission in Breeder Quails Under Heat Stress. AB - This experiment was carried out to investigate the combination effects of organic and inorganic chromium (Cr) on egg production, egg quality, reproductive response, and immune status of breeder quails and their offspring under heat stress. A total of 140 7-week-old Japanese breeder quails (120 females and 20 males) according to a completely randomized design were used in four treatment groups (five replicate and seven birds per each) lasted for 8 weeks. Quails exposed to 35 degrees C for 8 h/day for induction of cyclic heat stress treatments consisted of diets supplemented with (1) 1 mg CrCl3 per kilogram of diet as control (CNT); (2) 1 mg Cr-L-Met per kilogram of diet as organic Cr (OCr); (3) 0.5 mg CrCl3 plus 0.5 mg Cr-L-Met per kilogram of diet (ISO); (4) 1 mg CrCl3 plus 0.5 mg Cr-L-Met per kilogram of diet (On-top). Productive performance and egg quality parameters were determined weekly. Fertility, hatchability, and embryonic mortality were measured at the end of experiment. Humoral immunity was assessed by primary and secondary antibody titer in sheep red blood cells (SRBC) and Newcastle disease (ND) tests. Cell-mediated immunity was assessed by the cutaneous basophil hypersensitivity (CBH) test to phytohemagglutinin (PHA) at days 20 and 45 of age. White blood cell count and immunoglobulin Y (IgY) content in serum and yolk of breeders and in serum and yolk residues of offspring were also measured. Results showed that maximum egg production, egg shell thickness, and Haugh unit were observed in birds fed ISO and On-top diets (P <= 0.05). The highest (P <= 0.05) antibody levels in ND test were observed in birds fed with OCr, ISO, and On-top diets. The highest cellular response (P <= 0.05) was in 12 h after primary PHA injection and 12 and 24 h after secondary PHA injection in birds fed with On-top diets. The highest count of heterophil and (H/L) were gained in breeder quails fed with CNT diet, and the lowest of them were reached with On-top diet (P <= 0.05). Results showed that the highest IgY level in serum of breeder and their offspring and that of yolk suck and egg yolk were observed in birds fed with On-top diet (P <= 0.05). These results suggest that extra supplemental organic Cr in combination with CrCl3 could lead to higher egg production, egg quality, and immune status of breeder quails and their offspring. PMID- 29181822 TI - Schisandrin A reverses doxorubicin-resistant human breast cancer cell line by the inhibition of P65 and Stat3 phosphorylation. AB - BACKGROUND: Multidrug resistance (MDR) in breast cancer therapy occurs frequently. Thus, anti-MDR agents from natural products or synthetic compounds were tested extensively. We have also explored the reverse effect and mechanism of Schisandrin A (Sch A), a natural product, on MCF-7 breast cancer doxorubicin (DOX)-resistant subline MCF-7/DOX. METHODS: MTT assay was performed to measure the viability of MCF-7 cells to assess the reverse effect of Sch A. Western blot analysis was used to study the protein levels. Laser scanning confocal microscopy was performed to detect the intercellular DOX and Rhodamine 123 accumulation. The qRT-PCR was used to analysis the target gene expression. Dual-luciferase reporter assay was performed to test the transcriptional activity of P-glycoprotein (P gp). RESULTS: Sch A, at the concentration of 20 uM, showed selective reverse effect (better than the positive control, verapamil at 5 uM) on MCF-7/DOX cell line but not on BEL-7402/DOX, Hep G2/DOX, and K-562/DOX cells. In addition, Sch A enhanced DOX-induced cleavage of Caspase-9 and PARP levels by increasing intracellular DOX accumulation and inhibiting P-gp function. Furthermore, Sch A selectively suppressed P-gp at gene and protein levels in MCF-7/DOX cells which express high level of MDR1 but not MRP1, MRP3, or BCRP. Besides, Sch A showed inhibitory effect on P-gp transcriptional activity. Sch A significantly reduced p IkappaB-alpha (Ser32) and p-Stat3 (Tyr705) levels which mediate P-gp expression. In addition, Stat3 knockdown enhanced the reverse effect of siP65. The combined effect of siStat3 and siP65 was better than Sch A single treatment in MCF-7/DOX cells. CONCLUSION: Sch A specifically reverses P-gp-mediated DOX resistance in MCF-7/DOX cells by blocking P-gp, NF-kappaB, and Stat3 signaling. Inhibition of P65 and Stat3 shows potent anti-MDR effect on MCF-7/DOX cells. PMID- 29181823 TI - A case of acute kidney injury caused by granulomatous interstitial nephritis associated with sarcoidosis. AB - Sarcoidosis affects multiple organs including lung, heart and kidney. Sarcoidosis causes hypercalcemia, hypergammaglobulinemia, and rarely, granulomatous interstitial nephritis, resulting in renal stromal damage. Granulomatous interstitial nephritis is characterized as interstitial nephritis with noncaseating epithelioid granulomas. Diagnosing granulomatous interstitial nephritis before patient's death is challenging; hence, only few cases proven by renal biopsy have been reported till date. We present a case of acute kidney injury caused by granulomatous interstitial nephritis as a renal manifestation of sarcoidosis proven by renal biopsy, which can be confirmed by 18F fluorodeoxyglucose positron emission tomography/computed tomography. Glucocorticoid therapy was helpful for improving and maintaining her renal function over a 6-year period. PMID- 29181824 TI - AGEs-RAGE overexpression in a patient with smoking-related idiopathic nodular glomerulosclerosis. AB - We report a case of smoking-related idiopathic nodular glomerulosclerosis (ING) with overexpression of glomerular advanced glycation end products (AGEs) and their receptor (RAGE). A 59-year-old Japanese man with nephrotic syndrome, who had a smoking history of one pack of cigarettes per day for approximately 40 years, presented with a 3-year history of urinalysis abnormalities without clinical evidence of diabetic mellitus. The patient's leg edema progressively worsened over the previous 2 years, and he was admitted to our hospital. Renal biopsy showed mesangial expansion with diabetic Kimmelstiel-Wilson-like nodular lesions, glomerular basement thickening, and arteriosclerosis. No electron-dense deposits, fibrils, or microtubule deposits were seen in the glomeruli on electron microscopy. Skin AGE level measured using AGE reader was higher in this case than the average level in age-matched Caucasians. In addition, immunohistochemical analysis revealed that N-carboxymethyl lysine, one of the major AGEs, and RAGE were overexpressed and podocin expression was decreased in the peripheral area of the glomerular nodular lesions. These observations suggest that AGEs-RAGE system may be activated in smoking-related ING, possibly leading to the progression of renal dysfunction. PMID- 29181825 TI - A primary hepatic gastrinoma accompanied by hyperplasia of multi-nodular Brunner's glands. AB - BACKGROUND: Primary hepatic gastrinoma causing severe ulcerogenic syndrome is extremely rare. Herein, we report a case of primary hepatic gastrinoma accompanied by hyperplasia of multi-nodular Brunner's glands in a patient who instead, preoperatively, was suspected of having multiple duodenal gastrinomas and hepatic metastasis. CASE PRESENTATION: A 57-year-old woman consulted a clinic complaining of melena, intermittent abdominal pain, diarrhea, and vomiting which had persisted for about 3 years. Six months before her presentation, she underwent segmental resection of the jejunum for acute peritonitis due to the spontaneous jejunal perforation. A blood test revealed that her serum immunoreactive gastrin (IRG) level was 12,037 pg/mL. Subsequently, she was transferred to our hospital. On computed tomography (CT), a hypervascular tumor of 23 mm in the segment 5 (S5) region of the liver was visualized. A selective arterial secretagogue injection test (SASI test) was performed twice. The first SASI test revealed that the hepatic tumor was a gastrinoma, and there was no gastrinoma in the duodeno-pancreatic region. Additionally, somatostatin receptor scintigraphy only visualized the tumor in the liver. However, the second SASI test, which was performed during the administration of a proton pump inhibitor and a somatostatin analog (octreotide acetate), revealed that there may have been gastrinomas existing not only in the liver but also in the upper part of the duodenum or the head of the pancreas. Duodenal endoscopy revealed multiple submucosal tumors in the first and the second portion of the duodenum, although a pathological examination of biopsied specimens obtained from the duodenal lesions was negative for malignant cells. Multiple endocrine neoplasia type 1 (MEN1) was excluded from her family history, and serum levels of both intact parathyroid hormone (iPTH) and calcium were within normal ranges. An anterior segmentectomy of the liver and pancreas-preserving total duodenectomy were performed on September 9, 2013. Postoperatively, her serum immunoreactive gastrin level decreased to less than 50 pg/mL. Pathological study of the resected specimens revealed a gastrinoma in the liver, but no gastrinoma in the duodenum. Interestingly, the duodenal submucosal tumor-like lesions were hyperplastic Brunner's glands. Postoperatively, she has been well without recurrence of hypergastrinemia for 4 years. CONCLUSION: We report a case of primary hepatic gastrinoma in a patient who has been cured for 4 years postoperatively. The diagnosis was somewhat difficult due to the coexisting, multiple hyperplastic Brunner's glands of the duodenum mimicking the submucosal neuroendocrine tumors, which might have developed due to long-term hypergastrinemia. PMID- 29181826 TI - Speckle tracking imaging in inflammatory heart diseases. AB - Accurate diagnosis of acute myocarditis is important for the prognosis and risk stratification of these patients. Cardiac magnetic resonance (CMR) has become a major modality for diagnosis of myocarditis, but not widely available. In this study, we tried to evaluate regional and global longitudinal strain by speckle tracking echocardiography in patients with acute inflammatory myocardial diseases in correlation with CMR. Patients with suspected acute myocarditis were recruited prospectively. Clinical diagnosis was established based on clinical, electrocardiographic, laboratory and conventional echocardiographic data. All patients underwent CMR and repeat echocardiographic examination within 24 h of CMR. Echocardiographic examinations were analyzed offline with speckle tracking imaging software. Thirty-two patients with acute perimyocarditis and myopericarditis were included. Mean age was 29 +/- 8, 30 males. All patients presented with chest pain and an abnormal electrocardiogram, in 28 ST elevation was found. Troponin was elevated in 30 and was 0.7 +/- 0.5 ng/ml. Creatine kinase was 487 +/- 319 U. LVEF was 56 +/- 5%. Wall motion abnormalities were present in postero-lateral (53%), and inferior wall (21%). Delayed enhancement on CMR was found in 29 patients. Echocardiographic EF based on speckle tracking imaging correlated with CMR calculated EF. There was a positive correlation between the amplitude of regional strain and delayed enhancement, r = 0.52. Sensitivity and specificity of regional strain for prediction of delayed enhancement was 85 and 73% respectively. Speckle tracking imaging can help in the diagnosis of acute myocarditis when CMR is not readily available. Speckle tracking imaging based EF correlates with CMR calculated LVEF and with global strain. PMID- 29181827 TI - Reference ranges for three-dimensional feature tracking cardiac magnetic resonance: comparison with two-dimensional methodology and relevance of age and gender. AB - Myocardial deformation is a sensitive marker of sub-clinical myocardial dysfunction that carries independent prognostic significance across a broad range of cardiovascular diseases. It is now possible to perform 3D feature tracking of SSFP cines on cardiac magnetic resonance imaging (FT-CMR). This study provides reference ranges for 3D FT-CMR and assesses its reproducibility compared to 2D FT CMR. One hundred healthy individuals with 10 men and women in each of 5 age deciles from 20 to 70 years, underwent 2D and 3D FT-CMR of left ventricular myocardial strain and strain rate using SSFP cines. Good health was defined by the absence of hypertension, diabetes, obesity, dyslipidaemia, or any cardiovascular, renal, hepatic, haematological and systemic inflammatory disease. Normal values for myocardial strain assessed by 3D FT-CMR were consistently lower compared with 2D FT-CMR measures [global circumferential strain (GCS) 3D - 17.6 +/- 2.6% vs. 2D - 20.9 +/- 3.7%, P < 0.005]. Validity of 3D FT-CMR was confirmed against other markers of systolic function. The 3D algorithm improved reproducibility compared to 2D, with GCS having the best inter-observer agreement [intra-class correlation (ICC) 0.88], followed by global radial strain (GRS; ICC 0.79) and global longitudinal strain (GLS, ICC 0.74). On linear regression analyses, increasing age was weakly associated with increased GCS (R2 = 0.15, R = 0.38), peak systolic strain rate, peak late diastolic strain rate, and lower peak early systolic strain rate. 3D FT-CMR offers superior reproducibility compared to 2D FT-CMR, with circumferential strain and strain rates offering excellent intra- and inter-observer variability. Normal range values for myocardial strain measurements using 3D FT-CMR are provided. PMID- 29181828 TI - Influence of Inhaled Corticosteroids on Bronchial Inflammation and Pulmonary Function in Chronic Obstructive Pulmonary Disease with Moderate Obstruction. AB - Inflammation in the bronchial respiratory tract and lung parenchyma underlies the pathogenesis of chronic obstructive pulmonary disease (COPD). It consists of effector cell infiltration, changes in reticular basement membrane (RBM) thickness, and the content of inflammatory mediators. The aim of this study was to assess the influence of inhaled corticosteroids (ICS) on the number of inflammatory cells and RBM thickness in bronchial biopsies, and pulmonary function in patients with moderate COPD. Twenty four patients with newly diagnosed COPD were included into the study. Pulmonary function tests and fiber optic bronchoscopy with bronchial biopsies were performed before and after 12 month treatment in two groups: ICS- group (LABA plus anticholinergics) and ICS+ group (LABA plus anticholinergics plus ICS). We found that the addition of inhaled corticosteroids to the therapeutic regimen contributed to a reduction of RBM thickness, inflammation, and lung hyperinflation. The intensity of bronchial inflammatory infiltration had little effect on lung function. In conclusion, RBM thickness, an airway wall remodeling element, does not significantly affect the degree of airflow limitation. PMID- 29181829 TI - Long-term endurance training increases serum cathepsin S levels in healthy female subjects. AB - BACKGROUND: Circulating cathepsin S (CS) has been associated with a lower risk for breast cancer in a large Swedish cohort. Long-term physical activity has been shown to have beneficial effects on the development of various cancer subtypes, in particular breast and colorectal cancers. The aim of this study was to investigate the effect of long-term endurance sport on CS levels in females. MATERIAL AND METHODS: Thirty-six of 40 subjects completed the study. Subjects were told to increase their activity pensum for 8 months reaching 150 min/week moderate or 75 min/week intense exercise. Ergometries were performed at the beginning and the end of the study to prove/quantify the performance gain. Blood samples were drawn at baseline and every 2 months. Serum CS levels were measured by ELISA. To analyse the change and the progression of CS, Wilcoxon rank sum and Friedman tests were used. RESULTS: The sportive group (performance gain by > 4.9%) showed a significant increase of CS levels from 3.32/2.73/4.09 to 4.00/3.09/5.04 ng/ml (p = 0.008) corresponding to an increase of 20.5%. CONCLUSIONS: We could show a significant increase of circulating CS levels in healthy female subjects induced by long-term physical activity. CS, occurring in the tumour microenvironment, is well-known to promote tumour growth, e.g. by ameliorating angiogenesis. However, the role of circulating CS in cancer growth is not clear. As physical activity is known as preventive intervention, in particular concerning breast and colorectal cancers, and long-term physical activity leads to an increase of CS levels in female subjects, circulating CS might even be involved in this protective effect.

PMID- 29181832 TI - Pluronic-F127 composite film loaded with erythromycin for wound application: formulation, physicomechanical and in vitro evaluations. AB - Composite film dressings composed of pluronic F127 (PL)-pectin (PC) and pluronic (PL) F127-gelatin (GL) were investigated as potential drug delivery system for wound healing. Composite films were solvent cast by blending PL with PC or GL in different ratios using glycerol (2.5%) as plasticizer. Erythromycin (ER) (0.1%) was incorporated in films as model hydrophobic antibiotic. The optimized composite films were characterized for physical appearance, morphology, mechanical profile, and thermal behavior. In addition, drug release, antibacterial activity, and cytocompatibility of the films were investigated to assess their potential as drug delivery system. The composite films exhibited excellent wound dressing characters in terms of appearance, stability, and mechanical profile. Moreover, ER-loaded composite films released ER in controlled manner, exhibited antibacterial activity against Staphylococcus aureus, and were non-toxic to human skin fibroblast. These findings demonstrate that these composite films hold the potential to be formulated as antibacterial wound dressing. PMID- 29181831 TI - Molecular guidance cues in the development of visual pathway. AB - 70%-80% of our sensory input comes from vision. Light hit the retina at the back of our eyes and the visual information is relayed into the dorsal lateral geniculate nuclei (dLGN) and primary visual cortex (V1) thereafter, constituting the image-forming visual circuit. Molecular cues are one of the key factors to guide the wiring and refinement of the image-forming visual circuit during pre- and post-embryonic stages. Distinct molecular cues are involved in different developmental stages and nucleus, suggesting diverse guidance mechanisms. In this review, we summarize molecular guidance cues throughout the image-forming visual circuit, including chiasm determination, eye-specific segregation and refinement in the dLGN, and at last the reciprocal connections between the dLGN and V1. PMID- 29181833 TI - Influence of polymeric carrier on the disposition and retention of 20(R) ginsenoside-rg3-loaded swellable microparticles in the lung. AB - The objective of this study was to investigate the influence of differently charged biocompatible polymers, including chitosan (CS), hyaluronic acid (HA), and hydroxypropyl cellulose (HPC), on the disposition and retention of 20(R) ginsenoside-rg3 (Rg3)-loaded swellable microparticles in the lung. A high pressure homogenization method combined with spray drying was used to prepare Rg3 loaded microparticles. In vitro aerodynamic performance of different microparticles was characterized by the Next Generation Impactor (NGI). Retention of the swellable microparticles in the rat lung was investigated using bronchoalveolar lavage fluid method. Influence of drug loading, polymer molecular weight, and polymer charge on the properties of the swellable microparticles was investigated. It was found that drug loading had no significant influence on experimental mass median aerodynamic diameter (MMADe) and fine particle fraction (FPF). Increasing polymer molecular weight caused no remarkable change in MMADe value, but the FPF value decreased with the increase of polymer molecular weight. At the same molecular weight level, polymer structure and charge had no statistical influence on the in vitro aerodynamic properties of the microparticles and lung disposition, but it influenced the swelling and bioadhesion behavior and therefore lung retention profile. Desirable phagocytosis escapement and inhibition of A549 cell proliferation were achieved for the developed swellable microparticles. In conclusion, the lung retention of swellable microparticles can be adjusted by selecting polymeric carriers with different structure and charge. PMID- 29181834 TI - Ion-pair formation combined with a penetration enhancer as a dual strategy to improve the transdermal delivery of meloxicam. AB - The aim of the study was to develop a novel drug-in-adhesive patch for transdermal delivery of meloxicam (MLX). The formulation involved a strategy to combine a chemical enhancer with an ion-pair agent. Diethylamine (DETA) was selected as the counter ion to form the ion-pair agent MLX-DETA. MLX-DETA was characterized by nuclear magnetic resonance spectroscopy (NMR) and Fourier transform infrared spectroscopy (FTIR). The ion-pair lifetime (T life) of MLX DETA was 164.1 MUs. The water solubility of MLX-DETA was increased nearly 9.3 fold, compared with that of MLX. Oleic acid (OA) was selected as the chemical enhancer, and the optimized formulation consisted of 5% (w/w) MLX-DETA, 5% (w/w) oleic acid, and DURO-TAK(r) 87-4098 adhesive as the pressure-sensitive adhesive matrix. The permeation study in vitro showed that both the counter ion and chemical enhancer were effective in improving the skin permeation of MLX. Tissue distribution studies demonstrated that higher accumulation of MLX following application of the MLX-DETA patch to the skin could be obtained in rats compared with the MLX-patch group. In conclusion, to increase the skin absorption and obtain a sustained release for the transdermal delivery of MLX, preparation of a drug-in-adhesive patch by combining an ion pair (MLX-DETA) with a permeation enhancer (OA) is a suitable strategy.

Finally, we review nonpharmacologic and pharmacologic interventions for the treatment of cancer-related fatigue and the associated literature supporting their effectiveness. PMID- 29181835 TI - Nanoparticles in thermosensitive gel based composite nanosystem for ocular diseases. AB - The pentablock (PB) copolymers based composite nanosystems were designed to provide a long-term delivery of macromolecules to the back of the eye. A unique arrangement of each block (polyethylene glycol, polylactic acid, and polycaprolactone) with various molecular weights (PB-A and PB-B) was selected for the synthesis of nanoparticles (NPs) and thermosensitive gel (PB-C) by sequential ring-opening bulk copolymerization reaction. PB copolymers were characterized for their molecular weight and purity by 1H-NMR spectroscopy and crystallinity by PXRD. The macromolecule model drugs [lysozyme (Lyz ~ 14.5 kDa), IgG-Fab (~ 50 kDa), and IgG (~ 150 kDa)] were selected to delineate the effect of molecular weights on in vitro release profile of nanoformulations. Lyz-, Fab-, and IgG encapsulated NPs were prepared by double emulsion solvent evaporation method. The entrapment efficiency (EE%) and drug loading (DL%) of macromolecules was higher for PB-B copolymers due to its higher molecular weight and hydrophobicity compare to PB-A. The particle size range of NPs was ~ 200-270 nm. In vitro release profiles of Lyz-, Fab-, and IgG-encapsulated in NPs alone and NPs suspended in gel (composite nanosystem) demonstrated a minimal burst release and drug release over a long period. The effect of hydrodynamic diameter of macromolecules and hydrophobicity of PB copolymers was investigated on the release profile of nanosystems. In vitro biocompatibility study showed negligible cytokine (IL-1, IL 6, and TNF-alpha) release, which confirmed the safety of the PB copolymers. Based on the results, it is anticipated that long-term ocular delivery of macromolecules can be achieved through composite nanosystems. PMID- 29181837 TI - Expression of liver X receptors in normal and refractory carcinoma tissues of the human lung and pancreas. AB - Liver X receptors (LXRs) participate not only in maintaining cholesterol homeostasis but also in controlling cellular growth in many types of normal and tumor cells. We previously reported that LXRalpha was aberrantly expressed in human oral squamous cell carcinoma (HOSCC) tissues and cell lines, and that LXR stimulation led to significant reduction of proliferation of HOSCC cells via accelerating cholesterol efflux. Since LXRs and downstream proteins involved in cholesterol metabolism could be also applied as therapeutic targets in small cell lung carcinoma (SCLC) and pancreatic ductal adenocarcinoma (PDAC), we herein analyzed the distribution of LXR proteins in these refractory cancers as well as in normal human lung and pancreatic tissues. LXRbeta was observed in ciliated epithelial cells, bronchial gland epithelia, type II alveolar epithelia and alveolar macrophages of the lung, and was less expressed in bronchial basal cells and type I alveolar epithelia. In addition, LXRbeta was detected in epithelium of the pancreatic duct and acinar cells of the pancreas, and was weakly expressed in pancreatic islet cells. By contrast, LXRalpha expression was restricted to alveolar macrophages, and was not evident in any types of epithelial cells in the lung and pancreas. We also demonstrated that LXRbeta but not LXRalpha was abundantly expressed in nine cases of SCLC and twenty cases of PDAC tissues. These findings provide basic information for evaluating the efficacy of LXR targeted treatment in SCLC and PDAC. PMID- 29181838 TI - Hepatitis B reactivation and outcomes in persons treated with directly acting antiviral agents against hepatitis C virus: results from ERCHIVES. AB - BACKGROUND: Higher risk of hepatitis B reactivation (HBV-r) has been reported in patients with hepatitis C treated with newer directly acting antiviral agents (DAAs). AIM: To determine the proportion of persons who develop HBV-r and its clinical consequences among DAA treated vs pegylated interferon/ribavirin (PEG/RBV) treated persons. METHODS: We calculated the proportion of persons who developed HBV viral reactivation (HBV-r; new detectable HBV DNA or increase of >1 log10 ); serum alanine aminotransferase flare (>5 times baseline); all-cause mortality and hepatic decompensation in persons treated with a newer DAA regimen or PEG/RBV. Kaplan-Meier curves were used to demonstrate survival and hepatic decompensation by treatment group and HBV-r. RESULTS: In 34 632 persons treated with DAA and 23 475 treated with PEG/RBV, HBV-r rate per 1000 person-years was 30.04 (10.41, 49.67) and 25.42 (95% CI 17.23, 33.62) respectively (P = .8). When stratified by SVR or by baseline HBsAg status, HBV-r was not different between groups. Kaplan-Meier survival curves comparing each regimen stratified by presence or absence of HBV-r did not demonstrate a significant difference in incidence of hepatic decompensation over time. For overall survival, there was no difference between PEG/RBV treated persons with or without HBV-r. For DAA treated persons, those with HBV-r had a shortened survival, though the numbers at risk were small. CONCLUSIONS: HBV-r is relatively uncommon after DAA therapy and not higher than among those treated with a PEG/RBV regimen. The small numbers of persons treated with a DAA regimen who do develop HBV-r have a shortened survival compared to those without HBV-r.

PMID- 29181841 TI - Epidural therapy for the treatment of severe pre-eclampsia in non labouring women. AB - BACKGROUND: Pre-eclampsia is a pregnancy-specific multi-organ disorder, which is characterised by hypertension and multisystem organ involvement and which has significant maternal and fetal morbidity and mortality. Failure of the placental vascular remodelling and reduced uteroplacental flow form the etiopathological basis of pre-eclampsia. There are several established therapies for pre-eclampsia including antihypertensives and anticonvulsants. Most of these therapies aim at controlling the blood pressure or preventing complications of elevated blood pressure, or both. Epidural therapy aims at blocking the vasomotor tone of the arteries, thereby increasing uteroplacental blood flow. This review was aimed at evaluating the available evidence about the possible benefits and risks of epidural therapy in the management of severe pre-eclampsia, to define the current evidence level of this therapy, and to determine what (if any) further evidence is required. OBJECTIVES: To assess the effectiveness, safety and cost of the extended use of epidural therapy for treating severe pre-eclampsia in non labouring women. This review aims to compare the use of extended epidural therapy with other methods, which include intravenous magnesium sulphate, anticonvulsants other than magnesium sulphate, with or without use of the antihypertensive drugs and adjuncts in the treatment of severe pre-eclampsia.This review only considered the use of epidural anaesthesia in the management of severe pre-eclampsia in the antepartum period and not as pain relief in labour. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP) (13 July 2017) and reference lists of retrieved studies. SELECTION CRITERIA: Randomised controlled trials (RCTs) or quasi-RCTs comparing epidural therapy versus traditional therapy for pre-eclampsia in the form of antihypertensives, anticonvulsants, magnesium sulphate, low-dose dopamine, corticosteroids or a combination of these, were eligible for inclusion. Trials using a cluster design, and studies published in abstract form only are also eligible for inclusion in this review. Cross-over trials were not eligible for inclusion in this review. DATA COLLECTION AND ANALYSIS: The two review authors independently assessed trials for inclusion and trial quality. There were no relevant data available for extraction. MAIN RESULTS: We included one small study (involving 24 women). The study was a single centre randomised trial conducted in Mexico. This study compared a control group who received antihypertensive therapy, anticonvulsant therapy, plasma expanders, corticosteroids and dypyridamole with an intervention group that received epidural block instead of the antihypertensives, as well as all the other four drugs. Lumbar epidural block was given using 0.25% bupivacaine, 10 mg bolus and 5 mg each hour on continuous epidural infusion for six hours. This study was at low risk of bias in three domains but was assessed to be high risk of bias in two domains due to lack of allocation concealment and blinding of women and staff, and unclear for random sequence generation and outcome assessor blinding.The included study did not report on any of this review's important outcomes. Meta analysis was not possible.For the mother, these were: maternal death (death during pregnancy or up to 42 days after the end of the pregnancy, or death more than 42 days after the end of the pregnancy); development of eclampsia or recurrence of seizures; stroke; any serious morbidity: defined as at least one of stroke, kidney failure, liver failure, HELLP syndrome (haemolysis, elevated liver enzymes and low platelets), disseminated intravascular coagulation, pulmonary oedema.For the baby, these were: death: stillbirths (death in utero at or after 20 weeks' gestation), perinatal deaths (stillbirths plus deaths in the first week of life), death before discharge from the hospital, neonatal deaths (death within the first 28 days after birth), deaths after the first 28 days; preterm birth (defined as the birth before 37 completed weeks' gestation); and side effects of the intervention. Reported outcomesThe included study only reported on a single secondary outcome of interest to this review: the Apgar score of the baby at birth and after five minutes and there was no clear difference between the intervention and control groups.The included study also reported a reduction in maternal diastolic arterial pressure. However, the change in maternal mean arterial pressure and systolic arterial pressure, which were the other reported outcomes of this trial, were not significantly different between the two groups. AUTHORS' CONCLUSIONS: Currently, there is insufficient evidence from randomised controlled trials to evaluate the effectiveness, safety or cost of using epidural therapy for treating severe pre-eclampsia in non-labouring women.High-quality randomised controlled trials are needed to evaluate the use of epidural agents as therapy for treatment of severe pre-eclampsia. The rationale for the use of epidural is well-founded. However there is insufficient evidence from randomised controlled trials to show that the effect of epidural translates into improved maternal and fetal outcomes. Thus, there is a need for larger, well-designed studies to come to an evidence-based conclusion as to whether the lowering of vasomotor tone by epidural therapy results in better maternal and fetal outcomes and for how long that could be maintained. Another important question that needs to be answered is how long should extended epidural be used to ensure any potential clinical benefits and what could be the associated side effects and costs. Interactions with other modalities of treatment and women's satisfaction could represent other avenues of research. PMID- 29181840 TI - MYD88 wild-type Waldenstrom Macroglobulinaemia: differential diagnosis, risk of histological transformation, and overall survival. AB - MYD88 mutations are present in 95% of Waldenstrom Macroglobulinaemia (WM) patients, and support diagnostic discrimination from other IgM-secreting B-cell malignancies. Diagnostic discrimination can be difficult among suspected wild type MYD88 (MYD88WT ) WM cases. We systematically reviewed the clinical, pathological and laboratory studies for 64 suspected MYD88WT WM patients. World Health Organization and WM consensus guidelines were used to establish clinicopathological diagnosis. Up to 30% of suspected MYD88WT WM cases had an alternative clinicopathological diagnosis, including IgM multiple myeloma. The estimated 10-year survival was 73% (95% confidence interval [CI] 52-86%) for MYD88WT versus 90% (95% CI 82-95%) for mutated (MYD88MUT ) WM patients (Log-rank P < 0.001). Multivariate analysis only showed MYD88 mutation status (P < 0.001) as a significant determinant for overall survival. Diffuse large B-cell lymphoma (DLBCL) was diagnosed in 7 (15.2%) and 2 (0.76%) of MYD88WT and MYD88MUT patients, respectively (Odds ratio 23.3; 95% CI 4.2-233.8; P < 0.001). Overall survival was shorter among MYD88WT patients with an associated DLBCL event (Log rank P = 0.08). The findings show that among suspected MYD88WT WM cases, an alternative clinicopathological diagnosis is common and can impact clinical care. WM patients with MYD88WT disease have a high incidence of associated DLBCL events and significantly shorter survival versus those with MYD88MUT disease. PMID- 29181842 TI - Sofosbuvir and velpatasvir with or without voxilaprevir in direct-acting antiviral-naive chronic hepatitis C: patient-reported outcomes from POLARIS 2 and 3. AB - BACKGROUND: Chronic hepatitis C infection leads to impairment of patient-reported outcomes (PROs). Treatment with direct-acting antiviral regimens results in short and long-term improvement of these outcomes. AIM: To assess PROs in patients treated with a newly developed direct-acting antiviral, a fixed-dose combination of sofosbuvir/velpatasvir (SOF/VEL) with/without voxilaprevir (VOX). METHODS: The PRO data were collected from participants of POLARIS-2 and POLARIS-3 clinical trials (DAA-naive, all HCV genotypes). Participants self-administered SF-36v2, FACIT-F, CLDQ-HCV and WPAI:SHP instruments at baseline, during treatment, and in follow-up. RESULTS: Of 1160 patients, 611 received SOF/VEL/VOX and 549 received SOF/VEL (52.8 +/- 11.0 years, 55.9% male, 75.4% treatment-naive, 33.9% cirrhotic). The sustained viral response at 12 weeks (SVR12) rates were 95%-98%. During treatment, improvements in most PRO scores were significant (all but one P < .01) and ranged from, on average, +2.3 to +15.0 points (on a 0-100 scale) by the end of treatment. These improvements were similar between SOF/VEL/VOX and SOF/VEL arms (all P > .05). After treatment discontinuation, patients treated with both regimens achieved significant and clinically meaningful PRO gains (+2.7 to +16.7 by post-treatment week 12, +3.9 to +20.1 by post-treatment week 24; all but one P < .001). Multivariate analysis showed that depression, anxiety and cirrhosis were the most consistent independent predictors of PRO impairment while no association of PROs with the treatment regimen choice was found (all P > .05). CONCLUSIONS: The pan-genotypic regimens with SOF/VEL with or without VOX not only have excellent efficacy and safety, but also significantly positively impact patients' experience both during treatment and after achieving sustained virologic response in DAA-naive patients with HCV. PMID- 29181844 TI - Comparative efficacy of endodontic medicaments and sodium hypochlorite against Enterococcus faecalis biofilms. AB - BACKGROUND: Many studies have investigated the effectiveness of root canal irrigants and medicaments against Enterococcus faecalis. The aim of this study was to compare the efficacy of commonly used medicaments against E. faecalis cultured as a biofilm on dentine substrate. METHODS: An E. faecalis biofilm was established on human dentine slices using a continuous flow cell. Each test medicament (Ledermix, Ca(OH)2 , Odontopaste, 0.2% chlorhexidine and 50:50 combinations of Ledermix/Ca(OH)2 and Odontopaste/Ca(OH)2 ) was introduced into the flow cell and biofilms were harvested and quantitated by determining cellular protein. Cellular viability was determined using serial plating and the number of colony-forming units was normalized against cellular protein to allow treatment protocols to be compared. Qualitative scanning electron microscopy analyses of the biofilm were performed after a 48-h exposure to each test agent. RESULTS: Sodium hypochlorite achieved total bacterial elimination. Ledermix and Odontopaste had no significant effect on the E. faecalis biofilm. Ca(OH)2 and 50:50 combinations of Ca(OH)2 /Ledermix or Ca(OH)2 /Odontopaste reduced the viability by more than 99% while 0.2% chlorhexidine reduced bacterial numbers by 97%. CONCLUSIONS: Sodium hypochlorite remains the gold standard for bacterial elimination in root canal therapy. However, Ca(OH)2 in isolation and combined with Ledermix, and Odontopaste was highly effective in reducing bacterial viability. PMID- 29181843 TI - Genetic factors influencing prostate cancer risk in Norwegian men. AB - Norway has one of the highest rates of death due to prostate cancer (PCa) in the world. To assess the contribution of both common and rare single nucleotide variants (SNPs) to the prostate cancer burden in Norway, we assessed the frequency of the established prostate cancer susceptibility allele, HOXB13 G84E, as well as a series of validated, common PCa risk SNPs in a Norwegian PCa population of 779 patients. The G84E allele was observed in 2.3% of patients compared to 0.7% of control individuals, OR = 3.8, P = 1 * 10-4. While there was a trend toward an earlier age at diagnosis, overall the clinicopathologic features of PCa were not significantly different in G84E carriers and non carriers. Evaluation of 32 established common risk alleles revealed significant associations of risk alleles at 13 loci, including SNPs at 8q24, and near TET2, SLC22A3, NKX3-1, CASC8, MYC, DAP2IP, MSMB, HNF1B, PPP1R14A, and KLK2/3. When the data for each SNP are combined into a genetic risk score (GRS), Norwegian men within the top decile of GRS have over 5-fold greater risk to be diagnosed with PCa than men with GRS in the lowest decile. These results indicate that risk alleles of HOXB13 and common variant SNPs are important components of inherited PCa risk in the Norwegian population, although these factors appear to contribute little to the malignancy's aggressiveness. PMID- 29181845 TI - Interventions for preventing oral mucositis in patients with cancer receiving treatment: cytokines and growth factors. AB - BACKGROUND: Oral mucositis is a side effect of chemotherapy, head and neck radiotherapy, and targeted therapy, affecting over 75% of high-risk patients. Ulceration can lead to severe pain and difficulty with eating and drinking, which may necessitate opioid analgesics, hospitalisation and supplemental nutrition. These complications may disrupt cancer therapy, which may reduce survival. There is also a risk of death from sepsis if pathogens enter the ulcers of immunocompromised patients. Ulcerative oral mucositis can be costly to healthcare systems, yet there are few preventive interventions proven to be beneficial. Cytokines and growth factors may help the regeneration of cells lining of the mouth, thus preventing or reducing oral mucositis and its negative effects. OBJECTIVES: To assess the effects of cytokines and growth factors for preventing oral mucositis in patients with cancer who are receiving treatment. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (searched 10 May 2017); the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 4) in the Cochrane Library (searched 10 May 2017); MEDLINE Ovid (1946 to 10 May 2017); Embase Ovid (7 December 2015 to 10 May 2017); CINAHL EBSCO (Cumulative Index to Nursing and Allied Health Literature; 1937 to 10 May 2017); and CANCERLIT PubMed (1950 to 10 May 2017). The US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. SELECTION CRITERIA: We included parallel-design randomised controlled trials (RCTs) assessing the effects of cytokines and growth factors in patients with cancer receiving treatment. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the results of electronic searches, extracted data and assessed risk of bias. For dichotomous outcomes, we reported risk ratios (RR) and 95% confidence intervals (CI). For continuous outcomes, we reported mean differences (MD) and 95% CIs. We pooled similar studies in random-effects meta analyses. We reported adverse effects in a narrative format. MAIN RESULTS: We included 35 RCTs analysing 3102 participants. Thirteen studies were at low risk of bias, 12 studies were at unclear risk of bias, and 10 studies were at high risk of bias.Our main findings were regarding keratinocyte growth factor (KGF) and are summarised as follows.There might be a reduction in the risk of moderate to severe oral mucositis in adults receiving bone marrow/stem cell transplantation after conditioning therapy for haematological cancers (RR 0.89, 95% CI 0.80 to 0.99; 6 studies; 852 participants; low-quality evidence). We would need to treat 11 adults with KGF in order to prevent one additional adult from developing this outcome (95% CI 6 to 112). There might be a reduction in the risk of severe oral mucositis in this population, but there is also some possibility of an increase in risk (RR 0.85, 95% CI 0.65 to 1.11; 6 studies; 852 participants; low-quality evidence). We would need to treat 10 adults with KGF in order to prevent one additional adult from developing this outcome (95% CI 5 to prevent the outcome to 14 to cause the outcome).There is probably a reduction in the risk of moderate to severe oral mucositis in adults receiving radiotherapy to the head and neck with cisplatin or fluorouracil (RR 0.91, 95% CI 0.83 to 1.00; 3 studies; 471 participants; moderate-quality evidence). We would need to treat 12 adults with KGF in order to prevent one additional adult from developing this outcome (95% CI 7 to infinity). It is very likely that there is a reduction in the risk of severe oral mucositis in this population (RR 0.79, 95% CI 0.69 to 0.90; 3 studies; 471 participants; high-quality evidence). We would need to treat 7 adults with KGF in order to prevent one additional adult from developing this outcome (95% CI 5 to 15).It is likely that there is a reduction in the risk of moderate to severe oral mucositis in adults receiving chemotherapy alone for mixed solid and haematological cancers (RR 0.56, 95% CI 0.45 to 0.70; 4 studies; 344 participants; moderate-quality evidence). We would need to treat 4 adults with KGF in order to prevent one additional adult from developing this outcome (95% CI 3 to 6). There might be a reduction in the risk of severe oral mucositis in this population (RR 0.30, 95% CI 0.14 to 0.65; 3 studies; 263 participants; low -quality evidence). We would need to treat 10 adults with KGF in order to prevent one additional adult from developing this outcome (95% CI 8 to 19).Due to the low volume of evidence, single-study comparisons and insufficient sample sizes, we found no compelling evidence of a benefit for any other cytokines or growth factors and there was no evidence on children. There did not appear to be any serious adverse effects of any of the interventions assessed in this review. AUTHORS' CONCLUSIONS: We are confident that KGF is beneficial in the prevention of oral mucositis in adults who are receiving: a) radiotherapy to the head and neck with cisplatin or fluorouracil; or b) chemotherapy alone for mixed solid and haematological cancers. We are less confident about a benefit for KGF in adults receiving bone marrow/stem cell transplant after conditioning therapy for haematological cancers because of multiple factors involved in that population, such as whether or not they received total body irradiation (TBI) and whether the transplant was autologous (the patients' own cells) or allogeneic (cells from a donor). KGF appears to be a relatively safe intervention.Due to limited research, we are not confident that there are any beneficial effects of other cytokines and growth factors. There is currently insufficient evidence to draw any conclusions about the use of cytokines and growth factors in children. PMID- 29181846 TI - GOLM1 promotes prostate cancer progression through activating PI3K-AKT-mTOR signaling. AB - BACKGROUND: Prostate cancer (PCa) is the most commonly diagnosed cancer in men. Various molecular mechanisms account for PCa progression and elucidation of these mechanisms is key for selection of optimal therapies and improvement of patient outcome. Golgi membrane protein 1 (GOLM1) has been identified as a novel biomarker for PCa, but its biological functions and molecular mechanisms remain poorly understood. METHOD: GOLM1 expression was determined in PCa by tissue microarrays (TMAs) and real-time RT-PCR, Western blot, and immunohistochemistry (IHC) analyses. To investigate GOLM1 functions in vitro and in vivo, we overexpressed and knocked down GOLM1 in PCa cell lines and established xenograft mice models. A series of cytological function assays were used to determine the role of GOLM1 in cell proliferation, migration, invasion, and apoptosis. PI3K-AKT mTOR signaling pathway downstream of GOLM1 was detected by Western blot and IHC analyses. RESULT: GOLM1 expression is up-regulated in PCa of all stages and grades. GOLM1 promotes proliferation, migration and invasion, and inhibits apoptosis in PCa cell lines (DU145, PC3, and CWR22Rv1) and xenograft mice models. Moreover, PI3K-AKT-mTOR signaling is positively regulated by GOLM1, whereas PI3 K inhibitor BKM120 significantly abrogates the oncogenic functions of GOLM1. CONCLUSION: GOLM1 acts as a critical oncogene by promoting PCa cell proliferation, migration and invasion, and inhibiting apoptosis. GOLM1 plays oncogenic functions mainly through activating PI3K-AKT-mTOR signaling pathway. Therefore, agents that block PI3K-AKT-mTOR signaling pathway could be used in PCa patients with GOLM1 up-regulation. PMID- 29181847 TI - Achyranthes bidentata polypeptide protects dopaminergic neurons from apoptosis in Parkinson's disease models both in vitro and in vivo. AB - BACKGROUND AND PURPOSE: Parkinson's disease (PD) is a neurodegenerative disorder closely associated with dopaminergic neuron loss. It is well documented that Achyranthes bidentata polypeptides (ABPP) are potent neuroprotective agents in several kinds of neurons. Therefore, we proposed that ABPP might play a beneficial role against PD by protecting dopaminergic neurons from apoptosis. EXPERIMENTAL APPROACH: SH-SY5Y cells and primary rat dopaminergic neurons were pretreated with ABPP fraction k (ABPPk), a purified fraction of ABPP, and then the cells were exposed to 1-methyl-4-phenylpyridinium iodide (MPP+ ) to induce apoptosis. Cell viability, LDH activity, a Tunel assay and protein levels of Bcl 2 and Bax were analysed. In an in vivo PD model induced by MPTP, ABPPk was intranasally delivered to mice. Behavioural tests, immunohistochemistry, immunostaining, Nissl staining, qRT-PCR and Western blot were employed to evaluate the potential effects of ABPPk on PD in mice. KEY RESULTS: The application of ABPPk markedly enhanced the viability of SH-SY5Y cells and primary dopaminergic neurons treated with neurotoxic agent MPP+ . In an in vivo MPTP induced PD model, ABPPk significantly improved behavioural performances and prevented tyrosine hydroxylase loss in the substantia nigra pars compacta and striatum. Furthermore, we showed that MPTP-induced astrocyte and microglia activation were largely attenuated by ABPPk, leading to low levels of neuroinflammation and a downregulation of the apoptotic signalling pathway. CONCLUSION AND IMPLICATIONS: Taken together, our data show that ABPPk protects dopaminergic neurons from apoptosis, suggesting that ABPPk might be an effective intervention for treating the neuron loss associated with disorders such as PD.

PMID- 29181849 TI - The walking dead: sequential nuclear and organelle destruction during hair development. AB - BACKGROUND: Transition of hair shaft keratinocytes from actively respiring, nucleated cells to structural cells devoid of nucleus and cytoplasm is key to hair production. This form of cell 'death', or cornification, requires cellular organelle removal to allow the cytoplasm to become packed with keratin filament bundles that further require cross-linking to create a strong hair fibre. Although these processes are well described in epidermal keratinocytes, there is a lack of understanding of such mechanisms, specifically in the hair follicle. OBJECTIVES: To gain insights into cornification mechanisms within the hair follicle and thus improve our understanding of normal hair physiology. METHODS: Scalp biopsies and hair-pluck samples were obtained from healthy human donors and analysed microscopically after immunohistochemical staining. RESULTS: A focal point of respiratory activity was evident in keratogenous zone cells within the hair shaft, which also exhibited nuclear damage. Nuclear degradation occurred via both caspase-dependent and caspase-independent pathways. Conversely, mitophagy was driven by Bnip3L and restricted to the boundary of the keratogenous zone at Adamson's Fringe. CONCLUSIONS: We propose a model of stepwise living-dead transition within the first 1 mm of hair formation, whereby fully functional, nucleated cells first consolidate required functions by degrading nuclear DNA, yet continue to respire and provide the source of reactive oxygen species required for keratin cross-linking. Finally, as the cells become packed with keratin bundles, Bnip3L expression triggers mitophagy to rid the cells of the last remaining 'living' characteristic, thus completing the march from 'living' to 'dead' within the hair follicle. PMID- 29181851 TI - Life course evolution of body size and breast cancer survival in the E3N cohort. AB - Although adult obesity has been associated with poor breast cancer survival, data on adiposity at different periods in life and its lifelong evolution are scarce. Our aims were to assess the associations between breast cancer survival and body size during childhood, puberty and early adulthood and body size trajectories from childhood to adulthood. Self-assessed body size at age 8, at puberty, at age 20-25 and at age 35-40 and trajectories of body size of 4,662 breast cancer survivors from the prospective E3N cohort were studied in relation to risk of death from any cause, death from breast cancer and second invasive cancer event using multivariate Cox regression models. Four trajectories of body size were identified (T1 "moderate increase," T2 "stable/low increase," T3 "increase at puberty" and T4 "constantly high"). Compared with stable body size, an increase in body size during adult life was associated with an increased risk of death from any cause (HR T1 vs. T2 = 1.27; 95% CI = 1.01-1.60) and an increased risk of second invasive cancer event (HR T1 vs. T2 = 1.25; 95% CI = 1.06-1.47). Silhouettes at various ages were not associated with survival. Our results suggest that the evolution of body size from childhood to adulthood has a long term influence on breast cancer survival. Although these results need to be confirmed, this work sheds light on the need to combine lifelong approaches to current BMI to better identify breast cancer survivors who are at higher risk of recurrence or second primary cancer, or of death. PMID- 29181850 TI - Can non-clinical repolarization assays predict the results of clinical thorough QT studies? Results from a research consortium. AB - BACKGROUND AND PURPOSE: Translation of non-clinical markers of delayed ventricular repolarization to clinical prolongation of the QT interval corrected for heart rate (QTc) (a biomarker for torsades de pointes proarrhythmia) remains an issue in drug discovery and regulatory evaluations. We retrospectively analysed 150 drug applications in a US Food and Drug Administration database to determine the utility of established non-clinical in vitro IKr current human ether-a-go-go-related gene (hERG), action potential duration (APD) and in vivo (QTc) repolarization assays to detect and predict clinical QTc prolongation. EXPERIMENTAL APPROACH: The predictive performance of three non-clinical assays was compared with clinical thorough QT study outcomes based on free clinical plasma drug concentrations using sensitivity and specificity, receiver operating characteristic (ROC) curves, positive (PPVs) and negative predictive values (NPVs) and likelihood ratios (LRs). KEY RESULTS: Non-clinical assays demonstrated robust specificity (high true negative rate) but poor sensitivity (low true positive rate) for clinical QTc prolongation at low-intermediate (1*-30*) clinical exposure multiples. The QTc assay provided the most robust PPVs and NPVs (ability to predict clinical QTc prolongation). ROC curves (overall test accuracy) and LRs (ability to influence post-test probabilities) demonstrated overall marginal performance for hERG and QTc assays (best at 30* exposures), while the APD assay demonstrated minimal value. CONCLUSIONS AND IMPLICATIONS: The predictive value of hERG, APD and QTc assays varies, with drug concentrations strongly affecting translational performance. While useful in guiding preclinical candidates without clinical QT prolongation, hERG and QTc repolarization assays provide greater value compared with the APD assay. PMID- 29181852 TI - Optimal injection solution for endoscopic submucosal dissection: A randomized controlled trial of Western solutions in a porcine model. AB - BACKGROUND AND AIM: When carrying out endoscopic submucosal dissection (ESD), procedural safety increases with greater tissue elevation and efficiency increases with longer-lasting submucosal cushion. Fluids specifically developed for ESD in Asia are not commercially available in the West, leaving endoscopists to use a variety of injectable fluids off-label. To determine the optimal fluid available in the West, we compared commonly used fluids for Western ESD. METHODS: All phases were carried out in an ex vivo porcine stomach model. Phase 1 compared tissue elevation and duration of submucosal cushions produced by various standard volumes of various injectable solutions used for ESD. The two best-performing solutions used off-label were tested head-to-head in ESD in Phase 2. Phase 3 compared the best solution from Phase 2 to Eleview(r) , currently the only submucosal injection fluid approved in the USA. In Phases 2 and 3, five ESD were carried out with each solution. The solutions were randomized and the endoscopist blinded to the solution. RESULTS: The best-performing solutions in Phase 1 were 0.4% hyaluronic acid, 6% hydroxyethyl starch (HES), and Eleview(r) . Phase 2 compared 6% HES and hydroxypropyl methylcellulose (HPMC), showing that ESD with 6% HES was easier (P = 0.007), faster (P = 0.041) and required less injection volume (P = 0.003). In Phase 3, resection speed, ease of ESD and total volume per area resected were comparable between 6% HES and Eleview(r) . CONCLUSIONS: Of the submucosal injection fluids currently available in the West, Eleview(r) and 6% HES are the best-performing solutions for ESD in a porcine model. PMID- 29181854 TI - Assessing the similarity of dose response and target doses in two non-overlapping subgroups. AB - We consider 2 problems of increasing importance in clinical dose finding studies. First, we assess the similarity of 2 non-linear regression models for 2 non overlapping subgroups of patients over a restricted covariate space. To this end, we derive a confidence interval for the maximum difference between the 2 given models. If this confidence interval excludes the pre-specified equivalence margin, similarity of dose response can be claimed. Second, we address the problem of demonstrating the similarity of 2 target doses for 2 non-overlapping subgroups, using again an approach based on a confidence interval. We illustrate the proposed methods with a real case study and investigate their operating characteristics (coverage probabilities, Type I error rates, power) via simulation. PMID- 29181853 TI - Toward the elimination of hepatitis C in the United States. AB - The emergence of effective direct-acting antiviral (DAA) agents has reignited discussion over the potential for hepatitis C elimination in the United States. Eliminating hepatitis C will require a critical examination of technical feasibility, economic considerations, and social/political attention. Tremendous advancement has been made with the availability of sensitive diagnostic tests and highly effective DAAs capable of achieving sustained viral response (SVR) in more than 95% of patients. Eliminating hepatitis C also requires escalating existing surveillance networks to monitor for new epidemics. All preventive interventions such as clean syringe and needle exchange programs, safe injection sites, opioid substitution therapies, and mental health services need to be expanded. Although costs of DAAs have raised budget concerns for hepatitis C elimination, studies have shown that eliminating hepatitis C will produce a savings of up to 6.5 billion USD annually along with other intangible benefits such as increased work productivity and quality of life. Economic models and meta-analyses strongly suggest universal hepatitis C screening for all adults rather than just for birth cohort and high-risk populations. Social and political factors are at least as important as technical feasibility and economic considerations. Due to lack of promotion and public awareness, HCV elimination efforts continue to receive inadequate funding. Social stigma continues to impede meaningful policy changes. Eliminating hepatitis C is an attainable public health goal that will require intense collaboration and sustained public support. (Hepatology 2018;67:2449 2459). PMID- 29181855 TI - Liposomal encapsulation of silver nanoparticles enhances cytotoxicity and causes induction of reactive oxygen species-independent apoptosis. AB - Silver nanoparticles (AgNP) are one of the most widely investigated metallic NPs due to their promising antibacterial activities. In recent years, AgNP research has shifted beyond antimicrobial use to potential applications in the medical arena. This shift coupled with the extensive commercial applications of AgNP will further increase human exposure and the subsequent risk of adverse effects that may result from repeated exposures and inefficient delivery, meaning research into improved AgNP delivery is of paramount importance. In this study, AgNP were encapsulated in a natural biosurfactant, dipalmitoylphosphatidylcholine, in an attempt to enhance the intracellular delivery and simultaneously mediate the associated cytotoxicity of the AgNP. It was noted that because of the encapsulation, liposomal AgNP (Lipo-AgNP) at 0.625 MUg ml-1 induced significant cell death in THP1 cell lines a notably lower dose than that of the uncoated AgNP induced cytotoxicity. The induced cytotoxicity was shown to result in an increased level of DNA fragmentation resulting in a cell cycle interruption at the S phase. It was shown that the predominate form of cell death upon exposure to both uncoated AgNP and Lipo-AgNP was apoptosis. However, a reactive oxygen species-independent activation of the executioner caspases 3/7 occurred when exposed to the Lipo-AgNP. These findings showed that encapsulation of AgNP enhance AgNP cytotoxicity and mediates a reactive oxygen species-independent induction of apoptosis. PMID- 29181856 TI - Nanoconfined Oxidation Synthesis of N-Doped Carbon Hollow Spheres and MnO2 Encapsulated Sulfur Cathode for Superior Li-S Batteries. AB - The sulfur cathode, as a new generation of lithium-ion battery cathode material, has a high theoretical energy density of about 2500 Wh kg-1 . However, the low conductivity of sulfur and the "shuttle effect", widely presenting in the lithiation/de-lithiation process, seriously hinder its practical application. Here, we report a new nanoconfined oxidation route (first complete oxidation of metal sulfide and subsequently partial oxidation of the generated S from sulfide) for S cathode encapsulated with MnO2 nanosheets and N-doped carbon hollow spheres. This nanoconfined oxidation route can successfully confine the sulfur particles in the interior of the carbon shell, and the rationally introduced nonpolar carbon and polar MnO2 can both reduce the dissolution of polysulfide during the charge-discharge process. The obtained well-defined S-MnO2 @C cathode exhibits high specific capacity with excellent cycling performance and superior rate capability. PMID- 29181858 TI - Relationship between salivary haemoglobin and number of remaining teeth in older Koreans. AB - OBJECTIVE: We investigated the relationship between saliva and dental biofilm characteristics, oral hygiene behaviours and the number of remaining teeth in a sample of older Koreans. MATERIALS AND METHODS: This cross-sectional study included 133 participants, aged 65 years and older, recruited from senior welfare facilities in Incheon, South Korea. The outcome variable was the number of remaining teeth, and its associations with the independent variables of participants' general characteristics, salivary haemoglobin level, dental biofilm acidogenicity, salivary flow rate and oral hygiene behaviours were assessed. For statistical analyses, chi-squared test and step-wise multiple linear regression were used. RESULTS: The multiple linear regression model, which included all related factors identified in the bivariate analyses, showed that older adults who had high salivary haemoglobin levels (P < .05), brushed their teeth using the horizontal scrub method (P< .001), and did not use an interproximal cleaning device (P < .01) were more likely to have fewer remaining teeth. However, dental biofilm acidogenicity was not associated with the number of remaining teeth. CONCLUSION: The number of remaining teeth was associated with salivary haemoglobin level, appropriate toothbrushing technique and interdental cleaning. These findings suggest that the monitoring of salivary haemoglobin may contribute to the prevention of tooth loss caused by periodontal disease. PMID- 29181857 TI - Whole-exome sequencing of the BDR cohort: evidence to support the role of the PILRA gene in Alzheimer's disease. AB - AIM: Late-onset Alzheimer's disease (LOAD) accounts for 95% of all Alzheimer's cases and is genetically complex in nature. Overlapping clinical and neuropathological features between AD, FTD and Parkinson's disease highlight the potential role of genetic pleiotropy across diseases. Recent genome-wide association studies (GWASs) have uncovered 20 new loci for AD risk; however, these exhibit small effect sizes. Using NGS, here we perform association analyses using exome-wide and candidate-gene-driven approaches. METHODS: Whole-exome sequencing was performed on 132 AD cases and 53 control samples. Exome-wide single-variant association and gene burden tests were performed for 76 640 nonsingleton variants. Samples were also screened for known causative mutations in familial genes in AD and other dementias. Single-variant association and burden analysis was also carried out on variants in known AD and other neurological dementia genes. RESULTS: Tentative single-variant and burden associations were seen in several genes with kinase and protease activity. Exome wide burden analysis also revealed significant burden of variants in PILRA (P = 3.4 * 10-5 ), which has previously been linked to AD via GWAS, hit ZCWPW1. Screening for causative mutations in familial AD and other dementia genes revealed no pathogenic variants. Variants identified in ABCA7, SLC24A4, CD33 and LRRK2 were nominally associated with disease (P < 0.05) but did not withstand correction for multiple testing. APOE (P = 0.02) and CLU (P = 0.04) variants showed significant burden on AD. CONCLUSIONS: In addition, polygenic risk scores (PRS) were able to distinguish between cases and controls with 83.8% accuracy using 3268 variants, sex, age at death and APOE epsilon4 and epsilon2 status as predictors. PMID- 29181859 TI - Tumor invasion to the arteries feeding the gallbladder as a novel risk factor for cholecystitis after metallic stent placement in distal malignant biliary obstruction. AB - BACKGROUND AND AIM: Cholecystitis is a major complication after self-expandable metallic stent (SEMS) placement for malignant biliary obstruction. Ischemia is one of the risk factors for cholecystitis, but little is known about the influence of tumor invasion to the feeding artery of the gallbladder on the onset of cholecystitis after SEMS placement. The aim of the present study was to identify risk factors for cholecystitis after SEMS placement. METHODS: Incidence and nine predictive factors of cholecystitis were retrospectively evaluated in 107 patients who underwent SEMS placement for unresectable distal malignant biliary obstruction at Kyoto University Hospital and Otsu Red Cross Hospital between January 2012 and June 2016. RESULTS: Cholecystitis occurred in 13 of 107 patients (12.1%) after SEMS placement during the median follow-up period of 262 days. Univariate analyses showed that tumor invasion to the feeding artery of the gallbladder and tumor involvement to the orifice of the cystic duct were significant predictors of cholecystitis (P = 0.001 and P < 0.001). Multivariate analysis confirmed that these two factors were significant and independent risks for cholecystitis with odds ratios of 22.13 (95% CI, 3.57-137.18; P = 0.001) and 25.26 (95% CI, 4.12-154.98; P < 0.001), respectively. CONCLUSIONS: This study showed for the first time that tumor invasion to the feeding artery of the gallbladder as well as tumor involvement to the orifice of the cystic duct are independent risk factors for cholecystitis after SEMS placement. PMID- 29181860 TI - Detection of Helicobacter pylori in stool samples of young children using real time polymerase chain reaction. AB - BACKGROUND: The aims of this study were to develop and validate a multiplex real time polymerase chain reaction (q-PCR) assay of Helicobacter pylori in stool samples of healthy children. Additionally, we determined the prevalence of clarithromycin resistance and cagA gene in H. pylori-positive samples. MATERIALS AND METHODS: Archived stool samples from 188 children aged 6-9 years and 272 samples of 92 infants aged 2-18 months were tested for H. pylori antigens using enzyme immunoassay (EIA). A multiplex q-PCR assay was designed to detect H. pylori 16S rRNA and urease and the human RNase P gene as an internal control. Kappa coefficient was calculated to assess the agreement between q-PCR and EIA. RESULTS: Laboratory validation of the q-PCR assay using quantitated H. pylori ATCC 43504 extracted DNA showed S-shaped amplification curves for all genes; the limit of detection was 1 CFU/reaction. No cross-reactivity with other bacterial pathogens was noted. Applying the multiplex q-PCR to DNA extracted from fecal samples showed clear amplification curves for urease gene, but not for 16S rRNA. The prevalence of H. pylori infection was 50% (95% CI 43%-57%) by q-PCR (urease cycle threshold <44) vs 59% (95% CI 52%-66%) by EIA. Kappa coefficient was .80 (P < .001) and .44 (P < .001) for children aged 6-9 years and 2-18 months, respectively. Sixteen samples were positive for cagA and three were positive for clarithromycin resistance mutation (A2143G) as confirmed by sequencing. CONCLUSIONS: The developed q-PCR can be used as a cotechnique to enhance the accuracy of H. pylori detection in epidemiological studies and in clinical settings. PMID- 29181861 TI - Aneuploidy, TP53 mutation, and amplification of MYC correlate with increased intratumor heterogeneity and poor prognosis of breast cancer patients. AB - The clinical course of breast cancer varies from one patient to another. Currently, the choice of therapy relies on clinical parameters and histological and molecular tumor features. Alas, these markers are informative in only a subset of patients. Therefore, additional predictors of disease outcome would be valuable for treatment stratification. Extensive studies showed that the degree of variation of the nuclear DNA content, i.e., aneuploidy, determines prognosis. Our aim was to further elucidate the molecular basis of aneuploidy. We analyzed five diploid and six aneuploid tumors with more than 20 years of follow-up. By performing FISH with a multiplexed panel of 10 probes to enumerate copy numbers in individual cells, and by sequencing 563 cancer-related genes, we analyzed how aneuploidy is linked to intratumor heterogeneity. In our cohort, none of the patients with diploid tumors died of breast cancer during follow-up in contrast to four of six patients with aneuploid tumors (mean survival 86.4 months). The FISH analysis showed markedly increased genomic instability and intratumor heterogeneity in aneuploid tumors. MYC gain was observed in only 20% of the diploid cancers, while all aneuploid cases showed a gain. The mutation burden was similar in diploid and aneuploid tumors, however, TP53 mutations were not observed in diploid tumors, but in all aneuploid tumors in our collective. We conclude that quantitative measurements of intratumor heterogeneity by multiplex FISH, detection of MYC amplification and TP53 mutation could augment prognostication in breast cancer patients. PMID- 29181862 TI - Perforation and right ventricular outflow tract stenting: Alternative palliation for infants with pulmonary atresia/ventricular septal defect. AB - BACKGROUND: Right ventricular outflow tract (RVOT) stents have been used as palliation in patients with severe tetralogy of Fallot (TOF). Radiofrequency perforation of the RVOT has also been described in patients with pulmonary atresia (PA)/ventricular septal defect (VSD). However, RVOT stenting in conjunction with radiofrequency perforation as a means for establishing reliable pulmonary blood flow in patients with PA/VSD has not previously been reported. OBJECTIVES: Our aim is to report our experience with using perforation of plate like pulmonary valve atresia combined with stenting of RVOT as an alternative and equally efficacious intervention for infants with PA/VSD, as compared to a surgical pulmonary artery shunt (SPS). METHODS: A retrospective review of patients with PA/VSD at our institution from Jan 2006 to October 2015 was performed. RESULTS: Twenty-seven patients received palliation for PA/VSD. Five (median 2.5 kg, 2.1-4.1 kg) underwent RVOT stenting and 22 (3.5 kg, 2.1-4.6 kg) underwent surgical SPS. Of the patients who received an RVOT stent, 3 underwent guidewire perforation and balloon dilation of the plate-like pulmonary valve, and 2 underwent radiofrequency perforation of the pulmonary plate, followed by balloon dilation. Postprocedure saturations averaged 93% in the stent group and 89% in the shunt group. One of the patients who underwent RVOT stenting required additional stenting of the PDA for isolation of the LPA, but none required re intervention. Four patients in the SPS cohort required re-intervention (18%). Two required stenting of the shunt, and 2 required surgical revision of the shunt. There was one death in the stent group, however this was secondary to withdrawal of support given an underlying genetic diagnosis (trisomy 13). There was one fatality in the SPS cohort prior to hospital discharge. CONCLUSIONS: Perforation followed by RVOT stenting may be a safe and effective alternative to surgical SPS in infants with PA/VSD. PMID- 29181864 TI - Functions of the multi-interacting protein KIDINS220/ARMS in cancer and other pathologies. AB - Development of an organ and subsequently the whole system from an embryo is a highly integrated process. Although there is evidence that different systems are interconnected during developmental stages, the molecular understanding of this relationship is either not known or only to a limited extent. Nervous system development, amongst all, is maybe the most crucial and complex process. It relies on the correct distribution of specific neuronal growth factors and hormones to the specific receptors. Among the plethora of proteins that are involved in downstream signalling of neuronal growth factors, we find the kinase D interacting substrate of 220 kDa (KIDINS220), also known as ankyrin-rich repeat membrane spanning (ARMS) protein. KIDINS220 has been shown to play a substantial role in the nervous system and vascular system development as well as in neuronal survival and differentiation. It serves as a downstream regulator for many important neuronal and vascular growth factors such as vascular endothelial growth factor (VEGF), the neurotrophin family, glutamate receptors and ephrin receptors. Moreover, activation and differentiation of B- and T-cells, as well as tumour cell proliferation has also shown to be related to KIDINS220. This review comprehensively summarises the existing research data on this protein, with a particular interest in its role in cancer and in other pathologies. PMID- 29181863 TI - Confined Carbon Mediating Dehydroaromatization of Methane over Mo/ZSM-5. AB - Non-oxidative dehydroaromatization of methane (MDA) is a promising catalytic process for direct valorization of natural gas to liquid hydrocarbons. The application of this reaction in practical technology is hindered by a lack of understanding about the mechanism and nature of the active sites in benchmark zeolite-based Mo/ZSM-5 catalysts, which precludes the solution of problems such as rapid catalyst deactivation. By applying spectroscopy and microscopy, it is shown that the active centers in Mo/ZSM-5 are partially reduced single-atom Mo sites stabilized by the zeolite framework. By combining a pulse reaction technique with isotope labeling of methane, MDA is shown to be governed by a hydrocarbon pool mechanism in which benzene is derived from secondary reactions of confined polyaromatic carbon species with the initial products of methane activation.

AB - Extending the conjugation of viologen by a planar thiazolo[5,4-d]thiazole (TTz) framework and functionalizing the pyridinium with hydrophilic ammonium groups yielded a highly water-soluble pi-conjugation extended viologen, 4,4' (thiazolo[5,4-d]thiazole-2,5-diyl)bis(1-(3-(trimethylammonio)propyl)pyridin-1 ium) tetrachloride, [(NPr)2 TTz]Cl4 , as a novel two-electron storage anolyte for aqueous organic redox flow battery (AORFB) applications. Its physical and electrochemical properties were systematically investigated. Paired with 4 trimethylammonium-TEMPO (NMe -TEMPO) as catholyte, [(NPr)2 TTz]Cl4 enables a 1.44 V AORFB with a theoretical energy density of 53.7 Wh L-1 . A demonstrated [(NPr)2 TTz]Cl4 /NMe -TEMPO AORFB delivered an energy efficiency of 70 % and 99.97 % capacity retention per cycle. PMID- 29181866 TI - 'Last In-First Out': seasonal variations of non-structural carbohydrates, glucose 6-phosphate and ATP in tubers of two Arum species. AB - Knowledge on the metabolism of polysaccharide reserves in wild species is still scarce. In natural sites we collected tubers of Arum italicum Mill. and A. maculatum L. - two geophytes with different apparent phenological timing, ecology and chorology - during five stages of the annual cycle in order to understand patterns of reserve accumulation and degradation. Both the entire tuber and its proximal and distal to shoot portion were utilised. Pools of non-structural carbohydrates (glucose, sucrose and starch), glucose-6-phosphate and ATP were analysed as important markers of carbohydrate metabolism. In both species, starch and glucose content of the whole tuber significantly increased from sprouting to the maturation/senescence stages, whereas sucrose showed an opposite trend; ATP and glucose-6-phosphate were almost stable and dropped only at the end of the annual cycle. Considering the two different portions of the tuber, both ATP and glucose-6-phosphate concentrations were higher in proximity to the shoot in all seasonal stages, except the flowering stage. Our findings suggest that seasonal carbon partitioning in the underground organ is driven by phenology and occurs independently of seasonal climate conditions. Moreover, our results show that starch degradation, sustained by elevated ATP and glucose-6-phosphate pools, starts in the peripheral, proximal-to-shoot portion of the tuber, consuming starch accumulated in the previous season, as a 'Last In-First Out' mechanism of carbohydrate storage.

AB - A method is presented for the scalable preparation of high-quality graphdiyne nanotubes and ultrathin graphdiyne nanosheets (average thickness: ca. 1.9 nm) using Cu nanowires as a catalyst. For the storage of Li+ ions, the graphdiyne nanostructures show a high capacity of 1388 mAh g-1 and high rate performance (870 mA h g-1 at 10 A g-1 , and 449.8 mA h g-1 at 20 A g-1 ) with robust stability, demonstrating outstanding overall potential for its applications. PMID- 29181868 TI - Low molecular weight heparin as an anticoagulation strategy for left-sided ablation procedures. AB - OBJECTIVE: This quality improvement study was implemented to demonstrate consistent and reliable post procedure anticoagulation for patients undergoing left-sided ablations. We evaluated the safety and efficacy of anticoagulation practice during a transition from anticoagulation with overnight infusion of unfractionated heparin to a single subcutaneous injection of low molecular weight heparin. METHODS: Outcomes for patients who received unfractionated heparin from January 2014 to October 2014, were compared with outcomes of patients who received low molecular weight heparin from October 2014 to October 2015. Complications prepractice and postpractice change were documented and compared to establish confidence in the practice change and confirm the safety of the anticoagulation therapy management. RESULTS: There were no differences in the type or frequency of complications/adverse events demonstrated between the patients who had received unfractionated heparin for anticoagulation prophylaxis and those who received low molecular weight heparin. No thromboembolic events were reported or documented with either anticoagulation strategy. After confidence in the safety and efficacy of the practice change was established, a decision was made to discharge patients home the same day as there procedure, effectively reducing inpatient bed days and overall costs. CONCLUSION: Administration of low molecular weight heparin provides predictable anticoagulation and equally safe as unfractionated heparin when administered to patients post left-sided ablation. A secondary gain has been reduction of procedural costs by elimination of the previously required inpatient observation stay. PMID- 29181869 TI - Sample size re-estimation incorporating prior information on a nuisance parameter. AB - Prior information is often incorporated informally when planning a clinical trial. Here, we present an approach on how to incorporate prior information, such as data from historical clinical trials, into the nuisance parameter-based sample size re-estimation in a design with an internal pilot study. We focus on trials with continuous endpoints in which the outcome variance is the nuisance parameter. For planning and analyzing the trial, frequentist methods are considered. Moreover, the external information on the variance is summarized by the Bayesian meta-analytic-predictive approach. To incorporate external information into the sample size re-estimation, we propose to update the meta analytic-predictive prior based on the results of the internal pilot study and to re-estimate the sample size using an estimator from the posterior. By means of a simulation study, we compare the operating characteristics such as power and sample size distribution of the proposed procedure with the traditional sample size re-estimation approach that uses the pooled variance estimator. The simulation study shows that, if no prior-data conflict is present, incorporating external information into the sample size re-estimation improves the operating characteristics compared to the traditional approach. In the case of a prior-data conflict, that is, when the variance of the ongoing clinical trial is unequal to the prior location, the performance of the traditional sample size re-estimation procedure is in general superior, even when the prior information is robustified. When considering to include prior information in sample size re-estimation, the potential gains should be balanced against the risks. PMID- 29181870 TI - Lithium-Catalyzed Thiol Alkylation with Tertiary and Secondary Alcohols: Synthesis of 3-Sulfanyl-Oxetanes as Bioisosteres. AB - 3-Sulfanyl-oxetanes are presented as promising novel bioisosteric replacements for thioesters or benzyl sulfides. From oxetan-3-ols, a mild and inexpensive Li catalyst enables chemoselective C-OH activation and thiol alkylation. Oxetane sulfides are formed from various thiols providing novel motifs in new chemical space and specifically as bioisosteres for thioesters due to their similar shape and electronic properties. Under the same conditions, various pi-activated secondary and tertiary alcohols are also successful. Derivatization of the oxetane sulfide linker provides further novel oxetane classes and building blocks. Comparisons of key physicochemical properties of the oxetane compounds to selected carbonyl and methylene analogues indicate that these motifs are suitable for incorporation into drug discovery efforts. PMID- 29181871 TI - Outcome of 9 dogs treated with stereotactic radiation therapy for primary or metastatic vertebral osteosarcoma. AB - Primary and metastatic vertebral osteosarcoma (OSA) in the dog carries an overall guarded prognosis. Previously reported definitive treatments in dogs with vertebral OSA have included surgery, radiotherapy, chemotherapy or a combination of those therapies. This retrospective study was completed to determine patterns of failure, duration of local control and survival time in dogs with vertebral OSA treated with stereotactic radiation therapy (SRT). Nine dogs were treated with SRT for vertebral OSA. Protocols ranged from 1 to 5 fractions with total prescription ranging from 13.5 to 36 Gy. Six dogs had primary lesions and 3 had metastatic lesions. Neurologic score improved in 4 patients, remained the same in 4 and worsened in 1. Five of the 6 dogs that presented with assessable spinal pain had reported improvement in pain. Overall median survival time was 139 days and median duration of pain control was 77 days. There was not a statistically significant survival difference between dogs presenting with primary or metastatic disease, or dogs that had improvement in neurologic score following SRT. The data suggests similar survival times to the previously reported definitive treatments in dogs with vertebral OSA and displays continued difficulty in controlling this tumour. The dose limiting structure is the late responding spinal cord, but many of the patients herein died prior to the expected time to development of late radiation side effects. PMID- 29181872 TI - Validation of T1w-based segmentations of white matter hyperintensity volumes in large-scale datasets of aging. AB - INTRODUCTION: Fluid-attenuated Inversion Recovery (FLAIR) and dual T2w and proton density (PD) magnetic resonance images (MRIs) are considered to be the optimum sequences for detecting white matter hyperintensities (WMHs) in aging and Alzheimer's disease populations. However, many existing large multisite studies forgo their acquisition in favor of other MRI sequences due to economic and time constraints. METHODS: In this article, we have investigated whether FLAIR and T2w/PD sequences are necessary to detect WMHs in Alzheimer's and aging studies, compared to using only T1w images. Using a previously validated automated tool based on a Random Forests classifier, WMHs were segmented for the baseline visits of subjects from ADC, ADNI1, and ADNI2/GO studies with and without T2w/PD and FLAIR information. The obtained WMH loads (WMHLs) in different lobes were then correlated with manually segmented WMHLs, each other, age, cognitive, and clinical measures to assess the strength of the correlations with and without using T2w/PD and FLAIR information. RESULTS: The WMHLs obtained from T1w-Only segmentations correlated with the manual WMHLs (ADNI1: r = .743, p < .001, ADNI2/GO: r = .904, p < .001), segmentations obtained from T1w + T2w + PD for ADNI1 (r = .888, p < .001) and T1w + FLAIR for ADNI2/GO (r = .969, p < .001), age (ADNI1: r = .391, p < .001, ADNI2/GO: r = .466, p < .001), and ADAS13 (ADNI1: r = .227, p < .001, ADNI2/GO: r = .190, p < 0.001), and NPI (ADNI1: r = .290, p < .001, ADNI2/GO: r = 0.144, p < .001), controlling for age. CONCLUSION: Our results suggest that while T2w/PD and FLAIR provide more accurate estimates of the true WMHLs, T1w-Only segmentations can still provide estimates that hold strong correlations with the actual WMHLs, age, and performance on various cognitive/clinical scales, giving added value to datasets where T2w/PD or FLAIR are not available. PMID- 29181873 TI - Lambl's excrescences in children: Improved detection via transthoracic echocardiography. AB - BACKGROUND: Lambl's excrescences (LE) are fibrous extensions that can be found along the lines of closure of the aortic valve. Due to improvements in ultrasound technology, LE are frequently imaged during transthoracic echocardiography (TTE) in adults. OBJECTIVE: The purpose of this study was to determine the prevalence of LE among children from two eras (2004-2006 and 2011-2012) and the effect of technological advancements on LE detection. METHODS: TTE from 700 subjects (age 18 years old or younger) were reviewed. All parasternal long and short axis images of the aortic valve were reviewed by a board certified echocardiographer, and the positive studies were then reviewed by two additional observers to confirm the presence of LE. A two-sample t test with 95% significance was used to analyze the presence of LE in the cohorts. Median follow-up duration was 66 months. RESULTS: Of the 700 subjects, 12 (1.7%) children were found to have LE. No significant difference in prevalence was found between the two eras (.9% vs. 2.6%, P = .08) and the presence of LE was not related to age (P = .36). The youngest subject with an LE was 5 months old. During long-term follow-up there were no clinical events in the 12 children identified with a LE. CONCLUSIONS: The prevalence of LE in children is lower than that reported in adults, this supports the age-related "wear and tear" process that has been described in previous studies. LE do not require intervention or more aggressive invasive imaging in children. PMID- 29181874 TI - Using a statewide survey methodology to prioritize pediatric cardiology core content. AB - OBJECTIVE: Although pediatrician-reported relevance of Canadian cardiology specific objectives has been studied, similar data are not available for the 2016 American Board of Pediatrics (ABP) cardiology-specific objectives. This study asked Kentucky trainees, pediatricians, and pediatric cardiologists to identify "most important" content within these objectives. DESIGN, METHODS, OUTCOME MEASURES: This cross-sectional study used an original, online survey instrument based on the 2016 ABP cardiology-specific objectives. We collected quantitative data (numerical indications of importance) and qualitative data (open-ended replies regarding missing content and difficulty in teaching and learning). Respondents indicated the top two choices of most important items within eight content areas. Descriptive statistics (frequencies and percentages) and chi square analysis were calculated. Content within categories was organized using naturally occurring "clusters" and "gaps" in scores. Common themes among open ended qualitative responses were identified using Pandit's version of Glaser and Strauss Grounded theory (constant comparison). RESULTS: Of the 136 respondents, 23 (17%) were residents, 15 (11%) fellows, 85 (62%) pediatricians, and 13 (10%) pediatric cardiologists. Of attendings, 80% reported faculty/gratis faculty status. Naturally occurring clusters in respondent-designated importance resulted in <=3 "most selected" objectives per content area. Objectives in "most selected" content pertained to initial diagnosis (recognition of abnormality/disease) (n = 16), possible emergent/urgent intervention required (n = 14), building a differential (n = 8), and planning a workup (n = 4). Conversely, themes for "least selected" content included comanagement with subspecialist (n = 15), knowledge useful in patient-family communication (n = 9), knowledge that can be referenced (as needed) (n = 7), and longitudinal/follow-up concerns (n = 5). CONCLUSIONS: This study demonstrated the utility of an online survey methodology to identify pediatric cardiology content perceived most important. Learners and faculty generally provided concordant responses regarding most important content within the cardiology-specific ABP objectives. Medical educators could apply this methodology to inform curriculum revision. PMID- 29181875 TI - Integration of routine QA data into mega-analysis may improve quality and sensitivity of multisite diffusion tensor imaging studies. AB - A novel mega-analytical approach that reduced methodological variance was evaluated using a multisite diffusion tensor imaging (DTI) fractional anisotropy (FA) data by comparing white matter integrity in people with schizophrenia to controls. Methodological variance was reduced through regression of variance captured from quality assurance (QA) and by using Marchenko-Pastur Principal Component Analysis (MP-PCA) denoising. N = 192 (119 patients/73 controls) data sets were collected at three sites equipped with 3T MRI systems: GE MR750, GE HDx, and Siemens Trio. DTI protocol included five b = 0 and 60 diffusion sensitized gradient directions (b = 1,000 s/mm2 ). In-house DTI QA protocol data was acquired weekly using a uniform phantom; factor analysis was used to distil into two orthogonal QA factors related to: SNR and FA. They were used as site specific covariates to perform mega-analytic data aggregation. The effect size of patient-control differences was compared to these reported by the enhancing neuro imaging genetics meta-analysis (ENIGMA) consortium before and after regressing QA variance. Impact of MP-PCA filtering was evaluated likewise. QA-factors explained ~3-4% variance in the whole-brain average FA values per site. Regression of QA factors improved the effect size of schizophrenia on whole brain average FA values-from Cohen's d = .53 to .57-and improved the agreement between the regional pattern of FA differences observed in this study versus ENIGMA from r = .54 to .70. Application of MP-PCA-denoising further improved the agreement to r = .81. Regression of methodological variances captured by routine QA and advanced denoising that led to a better agreement with a large mega-analytic study. PMID- 29181877 TI - Formal and informal care for community-dwelling frail elderly people over time: A comparison of integrated and usual care in the Netherlands. AB - : While integration has become a central tenet of community-based care for frail elderly people, little is known about its impact on formal and informal care and their dynamics over time. The aim of this study was therefore to examine how an integrated care intervention for community-dwelling frail elderly people affects the amount and type of formal and informal care over 12 months as compared to usual care. A quasi-experimental design with a control group was used. Data regarding formal and informal care were collected from frail elderly patients (n = 207) and informal caregivers (n = 74) with pre/post-questionnaires. Within- and between-group comparisons and multiple linear regression analyses were performed. The results showed marginal changes over time in the amount of formal and informal care in both integrated care and usual care. However, different associations between changes in formal and informal care were found in integrated and usual care. Most notably, informal caregivers provided more instrumental assistance over time if formal caregivers provided less personal care (and vice versa) in integrated care but not in usual care. These results suggest that integrated care does not necessarily change the contribution of formal or informal care, but changes the interaction between formal (personal care) and informal (instrumental) activities. Implications and recommendations for research and practice are discussed. TRIAL REGISTRATION: Current Controlled Trials ISRNT05748494. PMID- 29181876 TI - Coumarin enhances nitrate uptake in maize roots through modulation of plasma membrane H+ -ATPase activity. AB - Coumarin is one of the simplest plant secondary metabolites, widely distributed in the plant kingdom, affecting root form and function, including anatomy, morphology and nutrient uptake. Although, some plant responses to coumarin have been described, comprehensive knowledge of the physiological and molecular mechanisms is lacking. Maize seedlings exposed to different coumarin concentrations, alone or in combination with 200 MUm nitrate (NO3- ), were analysed, through a physiological and molecular approach, to elucidate action of coumarin on net NO3- uptake rate (NNUR). In detail, the time course of NNUR, plasma membrane (PM) H+ -ATPase activity, proton pumping and related gene expression (ZmNPF6.3, ZmNRT2.1, ZmNAR2.1, ZmHA3 and ZmHA4) were evaluated. Coumarin alone did not affect nitrate uptake, PM H+ -ATPase activity or transcript levels of ZmNRT2.1 and ZmHA3. In contrast, coumarin alone increased ZmNPF6.3, ZmNAR2.1 and ZmHA4 expression in response to abiotic stress. When coumarin and NO3- were concurrently added to the nutrient solution, a significant increase in the NNUR, PM H+ -ATPase activity, together with ZmNAR2.1:ZmNRT2.1 and ZmHA4 expression was observed, suggesting that coumarin affected the inducible component of the high affinity transport system (iHATS), and this effect appeared to be mediated by nitrate. Moreover, results with vanadate, an inhibitor of the PM H+ -ATPase, suggested that this enzyme could be the main target of coumarin. Surprisingly, coumarin did not affect PM H+ -ATPase activity by direct contact with plasma membrane vesicles isolated from maize roots, indicating its possible elicitor role in gene transcription. PMID- 29181878 TI - Linear and Nonlinear Optical Properties of Tricyanopropylidene-Based Merocyanine Dyes: Synergistic Experimental and Theoretical Investigations. AB - New merocyanines dyes with tricyanopropylidene-based acceptor units connected to dihexylaminophenyl or dihexylaminothiophenyl donor moieties through polyenic bridges of different lengths have been designed. All derivatives exhibited a strong dipolar character and showed a typical intramolecular charge transfer (ICT) transition. NMR spectroscopy experiments combined with DFT calculations demonstrated that both the nature of the donor-acceptor pair and the length of the conjugated linker strongly impact the electronic structure of the dyes and induce alteration in the bond-length alternation (BLA) and marked shifts in the ICT absorption bands. Hyper-Rayleigh scattering experiments revealed an exponential increase in the second-harmonic generation response as the polyenic chain length was increased. Strikingly, the largest chromophores with the strongest donor-acceptor pair exhibited a very high first hyperpolarizabilty together with a cyanine-like electronic structure, which apparently contradicts the paradigm of optimal BLA predicted by the two-state model. Although it decreased as the polyenic chain length increased, all dyes also exhibited high thermal stability, which demonstrates their potential for applications in nonlinear optical devices. PMID- 29181880 TI - Histological evaluations and inflammatory responses of different dental implant abutment materials: A human histology pilot study. AB - BACKGROUND: Improvements of soft tissue to the abutment surface results in more stable peri-implant conditions, however, few human histological studies have compared soft tissue responses around different abutment materials. PURPOSE: To describe the peri-implant tissue around 3 abutment materials; titanium, zirconia, and gold alloy, over an 8-week healing period. MATERIALS AND METHODS: Fifteen edentulous sites were treated with implants. Eight weeks later, peri-implant tissue was harvested and processed using a nonseparation resin embedded technique. The tissue attachment characteristics were assessed at clinical stages using the gingival index (GI) score, surgical stage (surgical score), and histological stage (histological attachment percentage). Additionally, the inflammatory responses were evaluated using inflammatory extent and inflammatory cellularity grades. Nonparametrical statistics were used to describe the GI and surgical scores, and analytical statistics were used to analyze the histological attachment percentages as well as the inflammatory extent and cellularity grades amongst the 3 groups. RESULTS: There were no statistically significant differences among the groups for GI score (P = .071) and surgical score (P = .262). Titanium and zirconia exhibited nearly similar mean histological attachment percentages while gold alloy had a significantly lower percentage (P = .004). For the inflammatory extent and cellularity grades, the odds of being one grade higher for gold alloy abutment was 5.18 and 17.8 times that of titanium abutment, respectively. However, for the zirconia abutment, the odds were 0.87 and 7.5 times higher than the titanium group. CONCLUSIONS: The tissue around the gold alloy abutments resulted in worse attachment conditions compared with the titanium and zirconia abutments. Inflammation tended to be higher in the tissue around the gold alloy abutments than the titanium and zirconia abutments. PMID- 29181879 TI - High human herpesvirus 6 viral load in pediatric allogeneic hematopoietic stem cell transplant patients is associated with detection in end organs and high mortality. AB - Human Herpes Virus 6 (HHV-6) reactivation occurs in approximately half of patients following allogeneic hematopoietic stem cell transplant (HSCT). While encephalitis and delayed engraftment are well-documented complications of HHV-6 following HSCT, the extent to which HHV-6 viremia causes disease in children is controversial. We performed a retrospective review of HHV-6 reactivation and possible manifestations in pediatric allogeneic HSCT patients at a single institution. Of 89 children and young adults who underwent allogeneic HSCT over a three-and-a-half-year period, 34 patients reactivated HHV-6 early post transplant. Unrelated donor stem cell source and lack of antiviral prophylaxis were risk factors for the development of HHV-6 viremia. Viremia correlated with the presence of acute graft-versus-host disease, but not chronic graft-versus host disease. We identified two subgroups within the viremic patients-a high-risk viremic and tissue-positive group that reactivated HHV-6 and had suspected end organ disease and a low-risk viremic but asymptomatic group that reactivated HHV 6 but did not exhibit symptoms or signs of end-organ disease. Peak viral load was found to be strongly associated with mortality. Prospective studies in larger numbers of patients are needed to further investigate the role of HHV-6 in causing symptomatic end-organ disease as well as the association of viral load with mortality. PMID- 29181881 TI - Effects of triclosan on Japanese medaka (Oryzias latipes) during embryo development, early life stage and reproduction. AB - Triclosan has been shown to have endocrine-disrupting effects in aquatic organisms. In 2016, the US Food and Drug Administration banned the use of triclosan in consumer soaps. Before the ban, triclosan was reported at low concentrations in the aquatic environment, although the effect of triclosan on reproduction in teleost fish species is yet to be clarified. Here we investigated the effects of triclosan on embryo development and reproduction, and during the early life stage, in Japanese medaka (Oryzias latipes) by using Organisation for Economic Co-operation and Development tests 229, 212 and 210, with minor modifications. In adult medaka, exposure to 345.7 MUg l-1 suppressed fecundity and increased mortality but had no effect on fertility. Exposure to 174.1 or 345.7 MUg l-1 increased liver vitellogenin concentration in females but decreased liver vitellogenin concentration in males. With triclosan exposure, mortality was increased dose dependently during the embryonic and early larval stages, and a particularly steep increase in mortality was observed soon after hatching. The lowest observed effect concentrations of triclosan in Japanese medaka obtained in the present study (mortality [embryonic and larval stages, 276.3 MUg l-1 ; early life stage, 134.4 MUg l-1 ; adult stage, 174.1 MUg l-1 ], growth [134.4 MUg l-1 ], vitellogenin [174.1 MUg l-1 ], fecundity [345.7 MUg l-1 ] and fertility [>345.7 MUg l-1 ]) were at least 55 times (compared with the USA) and up to 13 400 times (compared with Germany) greater than the detected triclosan levels in the aquatic environment. These results suggest that triclosan may not be affecting fish populations in the aquatic environment. PMID- 29181882 TI - Heparin-induced thrombocytopenia complicating children after the Fontan procedure: Single-center experience and review of the literature. AB - Heparin-induced thrombocytopenia (HIT) is a life-threatening complication of heparin therapy. The risk for HIT correlates with the cumulative dosage of heparin exposure. In Fontan patients, recurrent systemic anticoagulation, traditionally with heparin, is used to alleviate the thrombotic complications that may occur postoperatively when the venous pressure rises and the systemic venous flow into the pulmonary arteries becomes sluggish, putting them at increased risk. As a pressure gradient-dependent circulation, elevation in systemic venous pressure, most often by venous thrombosis, contributes to circuit failure. Therefore, when HIT complicates patients after the Fontan procedure, it is associated with a high thrombotic morbidity and mortality; thus, a high index of suspicion is mandatory, based on the clinical signs of HIT. It is crucial to intervene early with alternative anticoagulants when HIT is suspected as this step may improve outcome in these patients. PMID- 29181883 TI - Real-time fMRI neurofeedback of the mediodorsal and anterior thalamus enhances correlation between thalamic BOLD activity and alpha EEG rhythm. AB - Real-time fMRI neurofeedback (rtfMRI-nf) with simultaneous EEG allows volitional modulation of BOLD activity of target brain regions and investigation of related electrophysiological activity. We applied this approach to study correlations between thalamic BOLD activity and alpha EEG rhythm. Healthy volunteers in the experimental group (EG, n = 15) learned to upregulate BOLD activity of the target region consisting of the mediodorsal (MD) and anterior (AN) thalamic nuclei using rtfMRI-nf during retrieval of happy autobiographical memories. Healthy subjects in the control group (CG, n = 14) were provided with a sham feedback. The EG participants were able to significantly increase BOLD activities of the MD and AN. Functional connectivity between the MD and the inferior precuneus was significantly enhanced during the rtfMRI-nf task. Average individual changes in the occipital alpha EEG power significantly correlated with the average MD BOLD activity levels for the EG. Temporal correlations between the occipital alpha EEG power and BOLD activities of the MD and AN were significantly enhanced, during the rtfMRI-nf task, for the EG compared to the CG. Temporal correlations with the alpha power were also significantly enhanced for the posterior nodes of the default mode network, including the precuneus/posterior cingulate, and for the dorsal striatum. Our findings suggest that the temporal correlation between the MD BOLD activity and posterior alpha EEG power is modulated by the interaction between the MD and the inferior precuneus, reflected in their functional connectivity. Our results demonstrate the potential of the rtfMRI-nf with simultaneous EEG for noninvasive neuromodulation studies of human brain function. PMID- 29181884 TI - miR-221/222 cluster expression improves clinical stratification of non-muscle invasive bladder cancer (TaT1) patients' risk for short-term relapse and progression. AB - Clinical heterogeneity of bladder cancer prognosis requires the identification of bladder tumors' molecular profile to improve the prediction value of the established and clinically used markers. In this study, we have analyzed miR 221/222 cluster expression in bladder tumors and its clinical significance for patients' prognosis and disease outcome. The study included 387 tissue specimens. Following extraction, total RNA was polyadenylated at 3'-end and reversed transcribed. SYBR-Green based qPCR assays were performed for the quantification of miR-221/222 expression. Extensive statistical analysis was completed for the evaluation of miR-221/222 cluster's clinical significance. The expression of miR 221/222 is significantly downregulated in tumors compared to normal urothelium, while ROC curve and logistic regression analysis highlighted cluster's discriminatory ability. However, miR-222 levels were increased in muscle-invasive (T2-T4) compared to superficial tumors (TaT1), and in high compared to low-grade tumors. Kaplan-Meier survival curves and Cox regression analysis revealed the stronger risk of TaT1 patients overexpressing miR-222 for disease short-term relapse and progression following treatment. Moreover, multivariate Cox models highlighted the independent prognostic value of miR-222 overexpression for TaT1 patients' poor prognosis. Finally, the analysis of miR-222 expression improved significantly the positive prediction strength of the clinically used prognostic markers of tumor stage, grade, EORTC risk-stratification and recurrence at the first follow-up cystoscopy for TaT1 patients' outcome, and resulted to higher clinical net benefit following decision curve analysis. In conclusion, the expression of miR-221/222 cluster is deregulated in bladder tumors and miR-222 overexpression results to a superior positive prediction of TaT1 patients' short term relapse and progression. PMID- 29181885 TI - Exploring PTDH-P450BM3 Variants for the Synthesis of Drug Metabolites. AB - The conversion of a series of pharmaceutical compounds was examined with three variants of cytochrome P450BM3 fused to phosphite dehydrogenase (PTDH) to enable cofactor recycling. Conditions for enzyme production were optimized, and the purified PTDH-P450BM3 variants were tested against 32 commercial drugs by using rapid UPLC-MS analysis. The sets of mutations (R47L/F87V/L188Q and R47L/F87V/L188Q/E267V/G415S) improved conversion for all compounds, and a variety of products were detected. Product analysis showed that reaction types included C hydroxylation, N-oxidation, demethylation, and aromatization. Interestingly, enzymatic aromatization could occur independent of the addition of reducing coenzyme. These results identified new conversions catalyzed by P450BM3 variants and showed that a small set of mutations in the oxygenase domain could broaden both substrate range and reaction type.

AB - This study aimed to provide new insights into the epidemiology of Salmonella in pig production, focusing on potential shedding patterns in breeding pigs throughout a full production cycle and the risk of transmission of infection from the sow to her offspring. A longitudinal study was conducted on five farrow-to finish commercial pig farms. In each herd, shedding of Salmonella in faeces was monitored in breeders through service, gestation and lactation. Swabs of the farrowing room floor and pools of faeces from piglets were collected on two occasions during lactation. Environmental pen swabs were also taken in the weaning and finisher houses. Salmonella isolates were serotyped, tested for antimicrobial resistance (AMR) and typed by Multiple-Locus Variable number tandem repeat Analysis (MLVA). Shedding by breeding pigs was low in all stages of the production cycle; 5% of sows shed at service, the production stage with highest risk of shedding (p < .01), 1.6% shed during gestation and 2.5% after farrowing. Salmonella was detected in 4% of piglet faecal pools in the second week post farrowing and 5% in the fourth week. Serotyping and AMR profiles of Salmonella isolates revealed that strains in sows and gilts were mostly different from strains isolated in weaner and finisher facilities. MLVA typing confirmed that the source of infection in piglets was in most instances the contaminated environment rather than their dam. Based on the typing results, it appears that sows do not pose a major risk in the maintenance and transmission of Salmonella to their progeny but instead the contaminated pen environment is more significant in the perpetuation of the organism on farm. PMID- 29181887 TI - Historic and geographic surveillance of Pseudogymnoascus destructans possible from collections of bat parasites. AB - Specimens archived in wet collections represent valuable material for scientific research. Here, we show that bat fly (Diptera, Nycteribiidae) samples contain DNA of Pseudogymnoascus destructans, a fungus pathogenic to bats. Using dual-probe quantitative PCR, we detected P. destructans DNA on bat flies collected in the Samara, Sverdlovsk and Irkutsk regions of Russia between 2005 and 2017. Fungal load was significantly lower on bat flies from wet collections than on freshly collected mites in the Czech Republic. The bat pathogen was present in the Samara region (European part of Russia) in 2005, that is, a year before recognition of white-nose syndrome in North America. As Samara and Irkutsk regions were identified as new positive locations of P. destructans, our data expand the known geographic distribution of P. destructans. We conclude that ethanol-stored ectoparasites can be used to identify the presence of pathogens in historic bat populations and understudied geographical regions.

AB - Computational modeling of the heart is a subject of substantial medical and scientific interest, which may contribute to increase the understanding of several phenomena associated with cardiac physiological and pathological states. Modeling the mechanics of the heart have led to considerable insights, but it still represents a complex and a demanding computational problem, especially in a strongly coupled electromechanical setting. Passive cardiac tissue is commonly modeled as hyperelastic and is characterized by quasi-incompressible, orthotropic, and nonlinear material behavior. These factors are known to be very challenging for the numerical solution of the model. The near-incompressibility is known to cause numerical issues such as the well-known locking phenomenon and ill-conditioning of the stiffness matrix. In this work, the augmented Lagrangian method is used to handle the nearly incompressible condition. This approach can potentially improve computational performance by reducing the condition number of the stiffness matrix and thereby improving the convergence of iterative solvers. We also improve the performance of iterative solvers by the use of an algebraic multigrid preconditioner. Numerical results of the augmented Lagrangian method combined with a preconditioned iterative solver for a cardiac mechanics benchmark suite are presented to show its improved performance. PMID- 29181890 TI - Pediatric acute kidney injury induced by concomitant vancomycin and piperacillin tazobactam. AB - BACKGROUND: Vancomycin is very commonly used in combination with piperacillin tazobactam (PTZ) as the initial empiric treatment for moderate-severe infection, whenever coverage for both methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa is required. The combination of vancomycin and PTZ in adults has recently been reported to significantly increase the risk of acute kidney injury (AKI) relative to vancomycin monotherapy; such reports in pediatrics, however, are sparse. METHODS: A retrospective chart review was conducted of pediatric patients, aged 0-14 years, who were admitted to the general wards or intensive care unit and developed AKI after receiving vancomycin and PTZ concomitantly for >48 h. AKI is defined as a decrease in estimated glomerular filtration rate >=50% from baseline. Cases were identified by reviewing the Adverse Drug Reaction program database at King Saud University Medical City in Saudi Arabia from January 2015 to June 2016. RESULTS: Eight children admitted to the present hospital and who received concomitant vancomycin and PTZ treatment for pneumonia (n = 7) or febrile neutropenia (n = 1) developed drug-induced nephrotoxicity. Drug Interaction Probability Scale (DIPS) score for causation assessment was 9 in all cases (highly probable). CONCLUSION: Caution in utilizing the combination of vancomycin and PTZ is warranted in pediatric patients. Health-care professionals should be vigilant if this combination is to be initiated, and ensure close monitoring of renal function. Antibiotic therapy de-escalation should be considered as soon as culture results are available. PMID- 29181891 TI - Fluid-structure interaction of a pulsatile flow with an aortic valve model: A combined experimental and numerical study. AB - The complex fluid-structure interaction problem associated with the flow of blood through a heart valve with flexible leaflets is investigated both experimentally and numerically. In the experimental test rig, a pulse duplicator generates a pulsatile flow through a biomimetic rigid aortic root where a model of aortic valve with polymer flexible leaflets is implanted. High-speed recordings of the leaflets motion and particle image velocimetry measurements were performed together to investigate the valve kinematics and the dynamics of the flow. Large eddy simulations of the same configuration, based on a variant of the immersed boundary method, are also presented. A massively parallel unstructured finite volume flow solver is coupled with a finite-element solid mechanics solver to predict the fluid-structure interaction between the unsteady flow and the valve. Detailed analysis of the dynamics of opening and closure of the valve are conducted, showing a good quantitative agreement between the experiment and the simulation regarding the global behavior, in spite of some differences regarding the individual dynamics of the valve leaflets. A multicycle analysis (over more than 20 cycles) enables to characterize the generation of turbulence downstream of the valve, showing similar flow features between the experiment and the simulation. The flow transitions to turbulence after peak systole, when the flow starts to decelerate. Fluctuations are observed in the wake of the valve, with maximum amplitude observed at the commissure side of the aorta. Overall, a very promising experiment-vs-simulation comparison is shown, demonstrating the potential of the numerical method. PMID- 29181892 TI - Comparison of peri-implant clinical and radiographic status around short (6 mm in length) dental implants placed in cigarette-smokers and never-smokers: Six-year follow-up results. AB - BACKGROUND: It is hypothesized that peri-implant clinical and radiographic inflammatory parameters (probing depth [PD], bleeding on probing [BOP] and plaque index [PI]; and radiographic (crestal bone loss [CBL]) are worse among cigarette smokers (CS) compared with never-smokers (NS) with short implants. PURPOSE: The present 6-year follow-up retrospective study compared the peri-implant clinical and radiographic parameters in CS and NS with short dental implants (6 mm in length). MATERIALS AND METHODS: Fifty-six male individuals were included. These individuals divided into 2 groups as follows: (a) Group-1: 29 self-reported systemically healthy CS with 48 short-implants; and (b) Group-2: 27 self-reported systemically healthy NS with 43 short implants. Peri-implant PD, PI, BOP, and CBL were measured. Group comparisons were done using the Kruskal-Wallis test and sample size was estimated. Level of significance was set at P values < .05. RESULTS: In groups 1 and 2, the follow-up durations were 6.2 +/- 0.1 years and 6.1 +/- 0.3 years, respectively. A cigarette smoking history of 8.9 +/- 3.6 pack years was reported by individuals in Group-1. At follow-up, scores of peri implant PD, BOP, PI, and mesial and distal CBL were comparable around short implants in both groups. CONCLUSION: Under strict oral hygiene maintenance protocols, short dental implants can remain functionally stable in CS in a manner similar to NS. PMID- 29181893 TI - Developing inclusive residential care for older lesbian, gay, bisexual and trans (LGBT) people: An evaluation of the Care Home Challenge action research project. AB - There have been substantial achievements in legislative and human rights for lesbian, gay, bisexual and transgender (LGBT) older people and their visibility in health and social care has equally increased. These appear to have surpassed the ability of care services to meet their needs given documented concerns about the accessibility, inclusiveness and safety of care services particularly institutionalised care. This requires systemic change not easy to operationalise. This paper describes an action research initiative where six care homes belonging to a national care provider, collaborated to assess and develop their services with the support of local LGBT "Community Advisors" and academic partners. Framed within Rogers' (2003) change management framework and combined with a participatory leadership approach, a programme of intervention was implemented comprising structured activities around seven key areas thought to promote LGBT inclusion. A formal evaluation was conducted involving 35 pre- and post intervention qualitative interviews with 18 people (community advisors; care home managers and senior managers). The findings are presented across three key themes (1) starting points on the journey; (2) challenges encountered along the journey (organisational and interpersonal); and (3) making change happen; opportunities, initiatives and gains. We make recommendations on the value of a programme approach for achieving tangible outcomes that demonstrate increased inclusion for older LGBT people living in long-term care settings. PMID- 29181894 TI - Review: Impact of Helicobacter pylori on Alzheimer's disease: What do we know so far? AB - BACKGROUND: Helicobacter pylori has changed radically gastroenterologic world, offering a new concept in patients' management. Over time, more medical data gave rise to diverse distant, extragastric manifestations and interactions of the "new" discovered bacterium. Special interest appeared within the field of neurodegenerative diseases and particularly Alzheimer's disease, as the latter and Helicobacter pylori infection are associated with a large public health burden and Alzheimer's disease ranks as the leading cause of disability. However, the relationship between Helicobacter pylori infection and Alzheimer's disease remains uncertain. METHODS: We performed a narrative review regarding a possible connection between Helicobacter pylori and Alzheimer's disease. All accessible relevant (pre)clinical studies written in English were included. Both affected pathologies were briefly analyzed, and relevant studies are discussed, trying to focus on the possible pathogenetic role of this bacterium in Alzheimer's disease. RESULTS: Data stemming from both epidemiologic studies and animal experiments seem to be rather encouraging, tending to confirm the hypothesis that Helicobacter pylori infection might influence the course of Alzheimer's disease pleiotropically. Possible main mechanisms may include the bacterium's access to the brain via the oral-nasal-olfactory pathway or by circulating monocytes (infected with Helicobacter pylori due to defective autophagy) through disrupted blood-brain barrier, thereby possibly triggering neurodegeneration. CONCLUSIONS: Current data suggest that Helicobacter pylori infection might influence the pathophysiology of Alzheimer's disease. However, further large-scale randomized controlled trials are mandatory to clarify a possible favorable effect of Helicobacter pylori eradication on Alzheimer's disease pathophysiology, before the recommendation of short-term and cost-effective therapeutic regimens against Helicobacter pylori-related Alzheimer's disease. PMID- 29181895 TI - Body composition, appetite-related hormones, adipocytokines, and heart failure in adult patients with congenital heart disease: A preliminary study. AB - OBJECTIVES: To assess body composition and relationships among body composition, appetite-related hormones, adipocytokines, and heart failure (HF) in adult patients with congenital heart disease (CHD). PATIENTS: This prospective study enrolled 46 consecutive adult patients with CHD and 12 age-matched healthy controls. The patients and control subjects were divided into four groups: 13 patients with Fontan circulation (group A), 16 patients with cyanosis (group B), 17 patients who previously underwent biventricular repair (group C), and 12 age matched healthy controls. DESIGN: Body composition was measured using InBody730, and levels of appetite-related hormones (ghrelin and leptin) and adipocytokines (leptin, interleukin-6, and tumor necrosis factor-alpha) were determined. Relationships of these measurements between severe HF, defined as New York Heart Association functional class III-IV and/or recent repeated unscheduled hospitalizations due to HF, were examined using univariate logistic analysis. RESULTS: Mean patient age was 32.1 +/- 7.4 years. The skeletal muscle mass was significantly decreased in groups A and B compared with that in controls. Interestingly, ghrelin levels in groups A and B were also significantly lower than those in controls. Univariate logistic analysis revealed that ghrelin level, percent body fat, and pulse oximetric oxygen saturation were significantly associated with severe HF. CONCLUSIONS: Patients with Fontan circulation and those with cyanosis might be at a risk of sarcopenia. Despite the decreased skeletal muscle mass and increased body fat, ghrelin levels in these patients were decreased. These changes might have a negative impact on HF in these patients.

AB - We conducted four bird biodiversity surveys in the Putao area of northern Myanmar from 2015 to 2017. Combined with anecdotal information collected between 2012 and 2015, we recorded 319 bird species, including two species (Arborophila mandellii and Lanius sphenocercus) previously unrecorded in Myanmar. Bulbuls (Pycnonotidae), babblers (Timaliidae), pigeons and doves (Columbidae), and pheasants and partridges (Phasianidae) were the most abundant groups of birds recorded. Species richness below 1 500 m a. s. l. was higher than species richness at higher elevations. Our results suggest that the current protected areas in this region should be expanded to lower elevations to cover critical conservation gaps. PMID- 29181903 TI - A new species of sisorid catfish of the genus Exostoma from the Salween drainage, Yunnan, China. AB - A new species of the sisorid catfish genus Exostoma Blyth, 1860 was collected from two hill-stream tributaries of the Nujiang (Salween River) drainage in Gaoligong Mountain, south-western Yunnan Province, China from 2003 to 2006 and from two tributaries of the Salween River in Cangyuan County, Lingcang Prefecture, Yunnan Province, China (in 2007) and in Yongde County, Lingcang Prefecture, Yunnan Province, China (in 2015). Exostoma gaoligongensesp. nov. is the 10th species of the genus and is most similar to E. vinciguerrae in morphology but can be distinguished by pelvic fin reaching anus vs. not reaching; maxillary barbels just reaching or slightly surpassing pectoral-fin origin vs. surpassing pectoral-fin origin or even reaching posterior end of gill membrane; abdominal vertebrae 23-25 vs. 25-27; length of dorsal fin/dorsal to adipose distance 90.3%-287.0% vs. 59.2-85.7.

PMID- 29181905 TI - Complete mitochondrial genome of the leaf muntjac (Muntiacus putaoensis) and phylogenetics of the genus Muntiacus. AB - The leaf muntjac (Muntiacus putaoensis) is an endemic deer species found in the east trans-Himalayan region. In recent years, population numbers have decreased due to heavy hunting and habitat loss, and little genetic data exists for this species, thus our knowledge of distribution rangs and population sizes likewise remain limited. We obtained mtDNA genes and the complete mitochondrial genome sequence of M. putaoensis using PCR, followed by direct sequencing. The complete mitogenome sequence was determined as a circular 16 349 bp mitochondrial genome, containing 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and one control region, the gene composition and order of which were similar to most other vertebrates so far reported. Most mitochondrial genes, except for ND6 and eight tRNAs, were encoded on the heavy strand. The overall base composition of the heavy strand was 33.1% A, 29.3% T, 24.2% C, and 13.4% G, with a strong AT bias of 62.4%. There were seven regions of gene overlap totaling 95 bp and 11 intergenic spacer regions totaling 74 bp. Phylogenetic analyses (ML and BI) among the Muntiacus genus based on the sequenced of mitogenome and ND4L-ND4 supported M. putaoensis as a member of Muntiacus, most closely related to M. vuquangensis. However, when analyses based on cyt b included two more muntjacs, M. truongsonensis was most closely related to M. putaoensis rather than M. vuquangensis, and together with M. rooseveltorum, likely forming a M. rooseveltorum complex of the species. This study will help in the exploration of the evolutionary history and taxonomic status of the leaf muntjac, as well as its protection as a genetic resource. PMID- 29181907 TI - ?

AB - BACKGROUND: There are several examples of inadequate staffing at local emergency medical communication centres (LEMCs) resulting in limited availability and long waits on the telephone. There are no guidelines for population size or the staffing of a LEMC. In the following, we present models of catchment areas and staffing. MATERIAL AND METHOD: Traffic intensity on Saturdays and Sundays was based on data on figures for patient contacts at seven LEMCs in 2014 and 2015. We defined the minimum optimal population base as at least 50 % probability of >= 10 contacts in the course of a night duty. The Erlang-C formula was used to estimate service level and hence staffing requirements on the basis of population and response-time requirements. We have surveyed the combined staffing requirements of all the LEMCs in Norway. RESULT: The minimum optimal population base was 29 134. In 2016, 48 of 103 LEMCs were smaller than this. In order to be able to satisfy the response-time requirements in the Norwegian Emergency Medicine Regulations, 112 LEMC night operators and 158 day operators would be necessary for the whole of Norway. A reduction of the response-time requirement from 120 to ten seconds would require 9.8 % more operators at night and 17 % more operators during the day. INTERPRETATION: The models we have presented provide a basis for planning the population base and staffing of LEMCs. Significantly stricter response-time requirements will result in limited need for more personnel. PMID- 29181932 TI - Cardiovascular disease and diabetes in patients with African or Asian background. AB - BACKGROUND: Population groups of different ancestry appear to have varying prevalence of diabetes, different risks of developing cardiovascular disease and different responses to certain drugs that are used for these conditions. We wished to review the literature in this field. MATERIAL AND METHOD: We have performed searches in several databases for systematic review articles published from the year 2000 onwards, and supplemented these with articles from reference lists, our own literature archives and a pyramid search in the Norwegian Electronic Health Library database. Altogether 37 articles were included. RESULTS: With regard to diagnosed diabetes, the prevalence of coronary heart disease and stroke varies among groups of South Asian, East Asian, African and European ancestry. In patients of South Asian ancestry, the risk of coronary heart disease appears to be twice that of Europeans, and the disease occurs 5-10 years earlier. The prevalence of stroke is especially high in persons of African ancestry. Risk factors such as dyslipidemia and hypertension are distributed differently among these groups. The therapeutic response to drugs such as beta blockers, ACE inhibitors and various statins differs; for example, statin doses in Asians may often be halved in relation to those used for Caucasians, and ACE inhibitors are not recommended as monotherapy for hypertension in persons of African ancestry. These differences are partly attributable to variations in genetic disposition. INTERPRETATION: The findings are clinically significant - better insight in this field enables optimal tailoring of treatment for each patient, with more rapid achievement of goals and reduced risk of adverse effects. The recommendations given in this article are consistent with and complement the Directorate of Health's revised guidelines for the treatment of diabetes. PMID- 29181934 TI - ?

AB - Irisin, a novel myokine produced in response to physical exercise by skeletal muscle, displays anabolic effect on bone and can improve the bone-loss-induced osteoporosis in hind limb suspended mice. It is well known that muscles positively impact the skeleton and in different sports, including soccer, total body bone mineral density (TB-BMD) is elevated. Therefore, we have investigated the correlation between irisin serum levels and total and bone sub-regional BMD in soccer players never studied before. In this study, Caucasian football players of Bari team have been enrolled. Their sera were collected to measure by ELISA kit irisin levels and by dual-energy X-ray absorptiometry (DEXA) analysis measurements of BMD (g * cm-2) in the whole body and different bone sub-regions (head, arms, legs, ribs, dorsal vertebrae, lumbar vertebrae, pelvis) were performed. The BMC (g) was measured in the whole body. By means of Pearson's (R) and Cohen's (d) coefficient we investigated the linear association between the irisin serum levels and BMD. In soccer players, we have found a positive correlation between irisin and TB-BMD as demonstrated by the values of Pearson and Cohen's (d) coefficient. Furthermore, linear association was detected between irisin and BMD of different bone-site such as right arm, lumbar vertebrae and head. A positive trend was also observed analyzing circulating levels of irisin and bone mineral content as well as total Z-score. In conclusion, we have demonstrated the correlation between irisin and total or bone sub-regional BMD in soccer players for the first time, an additional systemic effect of the "sport hormone" defined myokine. PMID- 29181954 TI - C3f is a potential tool for the staging of osteoarthritis. AB - An attractive method for osteoarthritis (OA) staging is the measurement of biochemical markers in biological fluids, which could reflect dynamic and quantitative changes in joint remodeling and therefore disease progression. Proteome analysis has been recognized as one of the most effective tools to explore biomarkers as it can furnish a wealth of information in both diagnosis and prognosis of diseases. We have recently described an innovative tool for peptidome and lipidome profiling of fluids based on mesoporous aluminosilicate (MPAS) and Matrix-Assisted Laser Desorption/Ionization time-of-flight Mass Spectrometry (MALDI-TOF MS). The aim of this study was to analyze peptide profiles of human synovial fluid in patients with different grade of OA using MALDI-TOF-MS technique in order to identify potential markers of disease progression. Twenty-five patients older than 50 years and affected by primary knee OA diagnosed according to clinical and radiological criteria were enrolled. For each patient a synovial fluid sample was aspirated from the affected knee and analyzed using MALDI-TOF-MS technique. A statistically significant difference in the normalized area of two peaks (m/z=1865 and m/z=2021) was detected among different stages of OA. The 2 peaks were identified as Complement C3 peptide fragments: C3f and C3f Des-Arg. The expression levels of these two peptides (m/z=1865 and 2021) decreased with the progression of OA degrees severity (rhos= 0.434, p=0.03, and rhos=-0.532, p=0.006, respectively). This marker may be a useful tool for assessing the severity of knee OA and it may be a novel target for drug discovery, specifically for the development of disease modifying OA drugs. However further studies are required to clarify the role of C3f in OA pathogenesis.

AB - A reliable and effective technique in case of limb salvage surgery after resection of extensive bone tumors is represented by the implant of modular or custom-made megaprosthesis. Fixation of the residual surrounding soft tissue on the implant represent a challenge for the surgeon and the use of a polyethylene terephthalate (PET) tube over it, also known as Trevira, is currently a common choice for reattachment with good clinical outcomes. We compared fibroblastic cell culture potential over simple titanium coating vs titanium surrounded by Trevira and evaluated cell viability and replication at 24, 48 and 72 h using MTT cell growth assay and scanning electron microscopy to determine if there was any difference in the potential of cell growth associated to the material used. No significant difference was found at different timings in terms of total cell count for cultures over the two materials, but the absolute cell count was slightly higher in the Trevira group in the early time points, reversing the trend at 72 h of incubation. Ninety-four % of the cells analyzed were vital, regardless of the materials involved in the experiment, confirming the biocompatibility of titanium and PET. According to the results shown, we are able to confirm the in vitro safety and efficacy, in terms of newly formed cells extension and adhesion pattern, of using an attachment tube made from Trevira fibers surrounding an oncological megaprosthesis in order to achieve the most anatomical reinsertion of remaining soft tissue following resection. PMID- 29181956 TI - Infectious diseases in Poland in 2015 AB - PURPOSE OF THE STUDY: This is the next annual analysis of the situation of infectious and parasitic diseasesin Poland in 2015 within the framework of the Epidemiological Chronicle of Przeglad Epidemiologiczny- Epidemiological Review. Its purpose is to identify potential threats to the health of populations from infectiousdiseases occurring in Poland with reference to other parts of the globe. MATERIAL AND METHODS: This paper is an introduction to more detailed studies of the epidemiologicalsituation of selected infectious diseases and summarizes the results of the surveillance of infectious diseasesin Poland in 2015. References to epidemiological situation in other countries are limited to situations that mayaffect current or potential occurrence of the disease in Poland.The main source of epidemiological information for this summary is the data from the reports of the State SanitaryInspection included in the annual bulletins "Infectious Diseases and Poisonings in Poland in 2015" and"Vaccination in Poland in 2015" (1, 2). The epidemiological situation of particular diseases is further elaboratedin the Epidemiological Chronicle of the same issue of the Epidemiological Review.Data on deaths are based on the presentation of the Demographic and Labor Market Department of the CentralStatistical Office on deaths from infectious and parasitic diseases registered in Poland in 2015 and earlier. RESULTS: For a long time, the most common diseases among epidemiological surveillance it is upper respiratorytract infections classified as "influenza and suspected influenza". In 2015, the number of cases was3,843,438 (9 994,7 / 100,000). As to compare with the 2014's incidence, this was an increase of 22.6%.In 2015, incidence of intestinal infections with etiology of salmonella increased by 2.8% compared to the previousyear, but compared to the median of 2009-2013 was 2.5% lower.A serious epidemiological problem is a strong upward trend in nosocomial infections including infections causedby Clostridium difficile. In 2015, 8.976 (23.3 / 100,000) of these cases were reported. They caused 491 deaths.Compared to the previous year, the increase in incidence was 39.8%. Compared with the median of 2009-2013it was an increase of 89.7%.In 2015, there was a continuation of observed for more than a dozen years the unfavorable trend of intestinalinfections caused by noroviruses. There were recorded at 3,637 (9.5 / 100,000) of those infections.Among viral intestinal infections, rotavirus infections in children are a particularly important problem. In 2015,as compared with 2014, the increase of incidence in the general population was not high, only 0.5%, but to themedian of 2009-2013 it was 44.4%.An important group of intestinal infections, diarrhea in children under 2 years of age, had a slight decrease (by0.3%) in the category of bacterial infections in 2015, but increased by 26.7% in the category of bacterial poisoningsand 5.9% in the category of viral infections.In 2015, there were 4956 cases of pertussis (512.9 / 100,000), which was an increase in the incidence comparedwith the previous year by 136.2%, and compared with the 2009-2013 median by 127.4%.After the epidemic of rubella outbreaks in 2013, in the year 2014, the incidence dropped by 84.7% and in 2015,the decrease was 65.9%. One case of congenital rubella has been reported.Most measles infections are imported infections or in contact with them in the country. In 2015 the number ofcases was 48 (0.12 / 100,000). In 2015, the number of invasive diseases caused by H. influenzae was 62 (0.16 /100,000). Compared to the previous year, this was an increase of 51.3%.The number of invasive diseases caused by Streptococcus pneumoniae in 2015 was 979 cases. Compared to2014, this was an increase of 39.0%. When compared with the median of 2009-2013, increase was 128.1%.In 2015, number of reported cases of hepatitis B was 3,518 (9.1 / 100,000), which was 122.7% higher than themedian of 2009-2013. Newly diagnosed C-type infections were reported to be 4,285 (11.1 / 100,000), an increaseof 91.6% over the median of 2009-2013. Such a large increase in reported cases is related, inter alia to the introductiona new, more sensitive case definition in 2014.The incidence of Lyme disease has been on the rise in the last fifteen years. In 2015, 13,625 cases (35.4 /100,000) were reported, which, with an insignificant decrease compared to 2014, gives rise to 49.1% over themedian of 2009-2013.The downward trend in the incidence of tuberculosis (all forms of tuberculosis) is clearly persistent. In 2015, theincidence of this disease decreased compared to the previous year from 17.4 to 16.7 / 100,000.In 2015 were reported 1,281 cases of newly diagnosed HIV (3,33 / 100,000). It was an increase of 13.0%. Thenumber of AIDS cases decreased by 13.5% compared to the previous year.Reported cases of malaria involve people who have been infected abroad in endemic malaria areas. In 2015 therewere reported 29 such cases.None of the cases of diphtheria, chronic childhood paralysis, rabies and viral hemorrhagic fever except for denguehave been reported in 2015. There were reported 12 cases of dengue imported from endemic regions.In Poland in 2015 number of deaths from all infectious and parasitic diseases was 2,199. The share of deaths dueto infectious diseases in the total number of deaths was 0.54% and mortality was 5.5 per 100,000 population. Themajority of deaths were caused by tuberculosis and its consequences (25.7%) and intestinal infections caused byClostridium difficile (23.2%). PMID- 29181957 TI - Measles in Poland in 2015 AB - BACKGROUND: In 1998 Poland, along with all other Member States in the WHO European Region, implementedMeasles Elimination Programme coordinated by WHO. It requires achieving and maintaining veryhigh vaccine coverage (>95%), recording all cases and suspected cases of measles, and laboratory testing ofall suspected measles cases in the WHO Reference Laboratory. In Poland it is a Laboratory of Department ofVirology, NIPH-NIH. In order to confirm or exclude the case of measles specific measles IgM antibodies shouldbe measured using Elisa test, or molecular testing (PCR) should be performed to detect the presence measlesvirus RNA in biological material. AIM: To assess epidemiological situation of measles in Poland in 2015, including vaccination coverage in Polishpopulation, and Measles Elimination Program implementation status. METHODS: The descriptive analysis was based on data retrieved from routine mandatory surveillance systemand published in the annual bulletins "Infectious diseases and poisonings in Poland in 2015" and "Vaccinationsin Poland in 2015", and measles case-based reports from 2015 sent to the Department of Epidemiology NIPHNIHby Sanitary Epidemiological Stations. RESULTS: In total, there were 48 measles cases registered in Poland in 2015 (incidence 0.12 per 100,000), fromwhich 30 cases (62.5%) were confirmed with laboratory test. That was less than in 2014 - when 110 cases werereported and incidence was 0,29.In 2015, a total number of reported cases and suspected cases of measles was133, among them 48 cases (incidence 0.12 per 100,000) meet the criteria and were registered in Poland. In comparisonto the previous year (110 cases; 0.29) there was registered dicrease in the number of cases. Thirty cases(36.1%) were confirmed with laboratory tests. The highest incidence rate was observed among children in agegroup 0-4 (0.59). In 2015, 26 cases (54.2%) were hospitalized due to measles. No deaths from measles were reported.Vaccination coverage of children and youth aged 2-11 years ranged from 77.9% do 99.5% (primary vaccinationin children born in 2009-2013) and from 71.5% do 88.9% (booster dose in children born in 2005-2008). SUMMARY AND CONCLUSIONS: The epidemiological situation of measles deteriorated in 2015 in comparisonto proceding year. The sensitivity of measles surveillance improved but is still insufficient. It is necessaryto further promote Measles Elimination Program in Poland, to improve measles surveillance system and tomaintain the high immunization coverage. PMID- 29181958 TI - Rubella in Poland in 2015 AB - BACKGROUND: In 2004, Poland has adopted the WHO goal of rubella elimination and congenital rubellasyndrome prevention. The main target of the Programme is to stop transmission of the virus in the environmentand prevention of congenital rubella cases between children. This can be achieved by carrying out the vaccination.Participation in the rubella elimination program requires clinical diagnosis of rubella to be confirmed withlaboratory test. A laboratory-confirmed case is a suspected case with a positive blood test for rubella-specificIgM or/ and isolation of rubella virus. Isolation of rubella viruses and genotyping is an important components forconfirming connections between cases or excluding cases during investigations.Vaccination against rubella was introduced in 1987, initially only in 13 year-old girls. Among men, the incidenceof measles remained high creating a risk of infection of non-immune pregnant women which may lead to thedevelopment of congenital rubella syndrome in the child. Since 2003, single jab vaccination against rubella,measles and mumps is used- MMR vaccine for all children: primary vaccination at the age 13-15 months. AIM: To assess epidemiological situation of rubella in Poland in 2015, including vaccination coverage in polishpopulation. METHODS: The descriptive analysis was based on data retrieved from routine mandatory surveillance systemand published in the annual bulletins "Infectious diseases and poisonings in Poland in 2015" and "Vaccinationsin Poland in 2015". RESULTS: In 2015, there was a decrease in the number of rubella cases - with registered 2 027 cases (in 2014- 5 891 cases) - and a decline in incidence (from 15.3 per 100 000 to 5.3). The highest incidence rate, regardlessof gender and the environment, was observed among children aged 0 4 years (46.7 per 100,000). The incidenceof rubella in boys and men was similar to the incidence in girls and women (5.5 versus 5.0). In 2015, no cases ofcongenital rubella syndrome were registered. SUMMARY AND CONCLUSIONS: In 2015, there was a decrease in the number of rubella cases. In PolandRubella is reported exclusively on the basis of the clinical picture. The proportion of laboratory tests confirming/excluding rubella infection is still very low in Poland. In 2015, only 1.1% of rubella cases were laboratoryconfirmed. PMID- 29181959 TI - Mumps in Poland in 2015 AB - BACKGROUND: Vaccination against mumps from 2003 is mandatory in Poland and given as two dose schemewith MMR vaccine (mumps, measles, and rubella). Earlier this vaccination was only recommended. Despiteobserved decline in mumps incidence for over a decade which is a result of conducted vaccinations, mumps isstill a common disease among the children (1-3). AIM: To assess epidemiological situation of mumps in Poland in 2015, including vaccination coverage in Polishpopulation, in comparison to previous years. METHODS: The descriptive analysis was based on data retrieved from routine mandatory surveillance systemand published in the annual bulletins "Infectious diseases and poisonings in Poland in 2015" and "Vaccinationsin Poland in 2015" (4;5). Mumps cases were classified according to the criteria of surveillance case definitionimplemented in the European Union (Commission Decision of 28 April 2008 amending Decision 2002/253/EC).National Immunisation Programme for year 2015 was also used (6). RESULTS: In total, there were 2 208 mumps cases registered in Poland in 2015. Incidence of mumps was 5.7per 100,000 and it was lower by 12,3% in comparison with 2014 and lower by 20.4% in comparison with medianfor the years 2009-2014. The highest incidence (9.1 per 100 000) was registered in Kujawsko-pomorskie andthe lowest (3.3) - in Podkarpackie voivodeship. The highest incidence rate was observed among children aged 5years (48.3 per 100 000). Incidence in men (7.1 per 100 000) was higher than in women (4.4). In 2015, 12 peoplewere hospitalized due to mumps. Vaccination coverage of children aged 3 years in Poland in 2015 was 96,3%and it was lower by 0.7% in comparison with year 2014. CONCLUSIONS: Systematic execution of mumps vaccination in accordance with the National ImmunisationProgramme resulted in a significant decrease in the number of registered cases. Due to the high vaccinationcoverage further decline in the number of cases is expected. PMID- 29181960 TI - A starch, glycyrretinic, zinc oxide and bisabolol based cream in the treatment of chronic mild-to-moderate atopic dermatitis in children: a three-center, assessor blinded trial. AB - BACKGROUND: Atopic dermatitis (AD) is a very common chronic inflammatory and eczematous skin condition characterized by flares and remissions. Skin barrier alteration or dysfunction is the most relevant patogenetic factor. Topical corticosteroids are the mainstay treatment of AD, especially during flare periods. The daily use of emollients and moisturizers is also considered a relevant adjunctive strategy to improve skin barrier function and skin appearance in AD patients. Long-term use of topical corticosteroids is associated with important drawbacks and side effects. A corticosteroid-free cream containing starch, glycyrretinic acid, zinc oxide and bisabolol (DermamidTM; Difa Cooper, Caronno Pertusella, Varese, Italy) has been designed for the treatment of acute eczematous conditions like diaper dermatitis. However, this formulation could be particularly suitable also for AD. We evaluated in a three-center, assessor blinded prospective 6-week treatment trial the efficacy and tolerability of this cream in children with chronic mild-to-moderate atopic dermatitis. METHODS: A total of 30 children (mean age 5 years, 18 males and 12 females) with chronic mild to moderate AD, affecting face, lower and upper limbs or trunk, were enrolled after parents' written informed consent. Exclusion criteria were a condition of immunosuppression, acute flares or a positive history of allergy to one of the components of the cream. The primary outcome was the evolution total eczema severity score (TESS) calculated as the sum of the single eczema severity score for each body area involved. Single area Eczema Severity Score (ESS) was calculated assessing eczema, infiltration, lichenification and scraching lesions using a 4-point scale grade (with 0=no sign, and 4=severe sign). A secondary endpoint was the percentage of subjects reaching at least 50% of TESS reduction at week 6 in comparison with baseline. The TESS was evaluated at baseline and after 3 and 6 weeks of treatment (twice daily application) in an assessor-blind fashion. RESULTS: At baseline the mean (SD) TESS was 11.6 (4.7). TESS was reduced significantly (P=0.0001) to 5.7 (3) after 3 weeks (-51%), and to 3.0 (2.3) at week 6 (-74%). Similar reductions were observed for single area ESS values. The percentage of subjects with at least a >50% reduction of TESS value at the end of the study was 87%. The product was very well tolerated. Only for one patient a mild burning sensation at the application site was reported. All the subjects concluded the trial. CONCLUSIONS: This trial supports the efficacy and the tolerability of a corticosteroid-free cream containing starch, glycyrretinic acid and bisabolol in the treatment of chronic mild to moderate atopic dermatitis in children. PMID- 29181961 TI - Atypical causes of bacterial osteoarticular infections in immunocompetent children. AB - Caring for a child with an osteoarticular infection or considering the possibility of an osteoarticular infection in a child is one of the most common clinical dilemmas encountered by clinicians caring for children. In such a scenario, one most often considers infection with frequently encountered pathogens such as Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae or Kingella kingae. A large variety of opportunistic osteoarticular pathogens may be found in the immunosuppressed patient or the postoperative or post-trauma patient, due to breaches in the immune system and nosocomial or post traumatic exposure to multiple organisms. However, an enlarging spectrum of less commonly encountered bacterial pathogens is also increasingly appreciated in community-acquired osteoarticular infections in otherwise healthy children, particularly in this era of pneumococcal and Haemophilus influenzae serotype B immunization. Given the limitations of culture-based detection methods in osteoarticular infections and the potentially unique therapeutic and diagnostic approaches necessitated by some of these pathogens, an awareness of these infections is necessary for proper detection and management. This review will discuss less commonly encountered bacterial osteoarticular pathogens that may infect otherwise healthy children, with emphasis on the epidemiology, diagnosis and treatment of each. PMID- 29181962 TI - Unmet needs in children with diabetes: the role of basal insulin. AB - The goal of insulin therapy in people affected by type 1 diabetes mellitus consists in achieving an optimal metabolic control and so HbA1c levels below 7.5%, according to the conclusions of relevant scientific studies. In any case it seems that this target is far from being achieved, mostly in the pediatric population. However, many important pharmacological, technological and cultural milestones have been placed both in therapy and management of insulin-dependent diabetes even if the gap between growing knowledge in these fields and its application in daily clinical practice appears still too wide. A fundamental component of these advancements concerns the design of new insulin basal analogues; molecules used to realize a basal-bolus model of therapy with MDI scheme. Degludec insulin has been recently approved for the pediatric utilization (aged 1 to 17 years). A registration trial for pediatric population (aged 6 to 17 years) is in progress for glargine U-300 insulin. These two insulin types have different biochemical and pharmacological properties and they represent two different ways to achieve the ideal basal analogue. Insulin degludec and insulin glargine U-300 are the newest basal analogues and each of them has proper pharmacokinetic and pharmacodynamic characteristics. Their characteristics represent an effort to create the ideal solution. The aim of this review is to summarize the pharmacokinetic and pharmacodynamic properties of these new insulins, to list the most significant scientific findings regarding their pharmacology as well as clinical uses, with particular reference to the pediatric population in order to declare them to clinical experience and to report data on an initial experience with these analogues, especially with degludec insulin. Once again, evolution goes through the specialized training of the staff involved in the care of the diabetic patient and the constant education of the latter.

PMID- 29181967 TI - Legionellosis in Poland in 2015 AB - OBJECTIVE: The aim of the study was to assess the epidemiological situation of legionellosis in Poland in2015 in comparison to the preceding years. MATERIAL AND METHODS: We reviewed data published in the annual bulletin: "Infectious diseases andpoisonings in Poland in 2015" and its prior versions along with the legionellosis case reports sent from Sanitary-Epidemiological Stations to the Department of Epidemiology of NIPH - NIH. RESULTS: In Poland, both two forms of legionellosis - Legionnaires' disease (a severe form of diseaseaccompanied by pneumonia) and Pontiac fever (mild, influenza-like form of infection) - are notifiable. In 2015,a total of 23 cases of Legionnaires' disease have been reported (there were no reports of Pontiac fever). Theannual incidence rate 0.060 (per 100,000 population) slightly increased when compared to previous year as wellas to the median (incidence) for 2009-2013. The infections were reported in 10 provinces, including five, whichin previous years usually did not register any cases; however, there is a number of provinces that did not identifyany LD cases in recent years. The incidence in males (0.097 per 100,000) was almost 4-times higher comparedto females (0.025). Except for one cluster of two, all cases were sporadic; All patients required hospitalization.The Sanitary Inspection reported four fatal cases - all men 43- 67 years/old. Eighteen cases were likely acquiredin the country, including a cluster of two cases linked with contaminated building water system. Four cases wereassociated with travels abroad (to Russia, Croatia, United Arab Emirates and USA) and in one case the exposureoccurred during the transport of goods (lorry driver). SUMMARY AND CONCLUSIONS: This study suggests, that legionellosis is likely under recognizedand under diagnosed in all provinces of the country. Geographical variations in incidence may reflect localdifferences in availability of laboratory tests for LD. Number of detected cases - without information on thenumber of laboratory tests performed - do not appear to be sufficient to fully assess the epidemiological situation. PMID- 29181968 TI - Growth Model of van der Waals Epitaxy of Films: A Case of AlN Films on Multilayer Graphene/SiC. AB - "Volmer-Weber" island nucleation and step-flow growth model are the classical processes of the conventional epitaxy of films. However, a growth model of van der Waals epitaxy (vdWE) of films is still not very well-documented. Here, we present an example of vdWE of AlN films on multilayer graphene (MLG)/SiC by hydride vapor phase epitaxy at a high temperature of 1100 degrees C and reveal the orientation relationship of AlN, MLG, and SiC as (0001)[1-100]AlN||(0001)[1 100]MLG||(0001)[11-20]SiC, which suggests that the vdWE heterointerface is not an usual covalent bond and no excessive strain during the growth process owing to the incommensurate in-plane lattices. Remarkably, zigzag cracks are formed because of the anisotropy of strain after the films are cooled down to room temperature, indicating that the growth model of vdWE is different from that of conventional epitaxy. It is a layer-by-layer epitaxy, and a planar substrate without a miscut angle is essential for obtaining single-crystalline films. Additionally, the films can be transferred to foreign substrates by direct mechanical exfoliation without any stressor layer. An ultraviolet photosensor device illustrates an example of III-nitride heterogeneous integration application. Our work demonstrates an excellent step toward the vdWE of varieties of compound films on 2D materials for the applications of transferrable heterogeneous integration in future. PMID- 29181969 TI - DNAzyme Based Nanomachine for in Situ Detection of MicroRNA in Living Cells. AB - The capability of in situ detection of microRNA in living cells with signal amplification strategy is of fundamental importance, and it will open up a new opportunity in development of diagnosis and prognosis of many diseases. Herein we report a swing DNA nanomachine for intracellular microRNA detection. The surfaces of Au nanoparticles (NPs) are modified by two hairpin DNA. We observe that one DNA (MB2) will open its hairpin structure upon partial hybridization with target miR-21 after entering into cells, and the other part of its hairpin structure could further react with the other hairpin DNA (MB1) to form a Zn2+-specific DNAzyme. This results in the disruption of MB1 through shearing action and the release of fluorescein Cy5. To provide an intelligent DNA nanomachine, MB2 is available again with the shearing action to bind with MB1, which provides effective signal amplification. This target-responsive, DNA nanomachine-based method showed a detection limit of 0.1 nM in vitro, and this approach could be an important step toward intracellular amplified detection and imaging of various analytes in living cells. PMID- 29181970 TI - Catalyst-Controlled Structural Divergence: Selective Intramolecular 7-endo-dig and 6-exo-dig Post-Ugi Cyclization for the Synthesis of Benzoxazepinones and Benzoxazinones. AB - Metal catalyzed post-Ugi cyclization of bis-amides is reported in this study. Exposure of bis-amides to Pd(II) catalyst triggered the formation of seven membered benzoxazepinones. This investigation established that changing the catalyst to a Echavarren's gold(I) turned off cyclization to seven member ring and turned on 6-exo-dig annulations to afford family of six-membered benzoxazinones. To support the proposed mechanisms, quantum chemical based density functional theory calculations have been performed and validated. This novel method obtained molecular complexity up to four modular inputs and divergence of two different skeletons. 2D NMR spectroscopic techniques and single crystal X-ray diffraction established the proposed structures. PMID- 29181971 TI - Synthesis of Vinyl-, Allyl-, and 2-Boryl Allylboronates via a Highly Selective Copper-Catalyzed Borylation of Propargylic Alcohols. AB - An efficient methodology for the synthesis of vinyl-, allyl-, and (E)-2-boryl allylboronates from propargylic alcohols via Cu-catalyzed borylation under mild conditions is reported. In the presence of commercially available Cu(OAc)2 or Cu(acac)2 and Xantphos, the reaction affords the desired products in up to 92% yield with a broad substrate scope (43 examples). Isolation of an allenyl boronate as the reaction intermediate suggests that an insertion-elimination-type reaction, followed by borylcupration, is involved in the borylation of propargylic alcohols. PMID- 29181972 TI - Fully Elastic Conductive Films from Viscoelastic Composites. AB - We investigated, for the first time, the conditions where a thermoplastic conductive composite can exhibit completely reversible stretchability at high elongational strains (epsilon = 1.8). We studied a composite of Au nanosheets and a polystyrene-block-polybutadiene-block-polystyrene block copolymer as an example. The composite had an outstandingly low sheet resistance (0.45 Omega/sq). We found that when a thin thermoplastic composite film is placed on a relatively thicker chemically cross-linked elastomer film, it can follow the reversible elastic behavior of the bottom elastomer. Such elasticity comes from the restoration of the block copolymer microstructure. The strong adhesion of the thermoplastic polymer to the metallic fillers is advantageous in the fabrication of mechanically robust, highly conductive, stretchable electrodes. The chemical stability of the Au composite was used to fabricate high luminescence, stretchable electrochemiluminescence displays with a conventional top-bottom electrode setup and with a horizontal electrode setup. PMID- 29181973 TI - Selective Separation and Preconcentration of Scandium with Mesoporous Silica. AB - Separation and preconcentration of scandium (Sc) were successfully achieved using a mesoporous silica support that showed good selectivity for this element. Unmodified mesoporous silica materials were used as an extracting medium in a solid-liquid extraction (SLE) process. Selectivity, extraction capacity, kinetics of extraction, and reusability under acidic conditions were investigated. The results demonstrate the potential of unmodified mesoporous silica materials for the selective separation and preconcentration of Sc. As no chelating ligand was grafted on the silica surface, which is often the case for most solid-phase extraction media for metal-ion separation, the experimental data allow us to hypothesize that the accessible silanols on the material surface are responsible for the selective Sc extraction. This interesting feature would drastically decrease the cost of solid-liquid extraction systems by using unmodified mesoporous silica materials. Moreover, a leachate solution obtained from a real rare-earth element ore was used to determine the performances of the proposed materials in a packed column configuration. The maximum Sc adsorption on the silica material surfaces is moderate (1 mg/g), but it is balanced by a great concentration factor (more than 100 times). The extraction performances are potentially promising, both in terms of selectivity and preconcentration, under the acidic conditions tested. PMID- 29181974 TI - ATP-Activatable Photosensitizer Enables Dual Fluorescence Imaging and Targeted Photodynamic Therapy of Tumor. AB - Targeted delivery of intracellular stimuli-activatable photosensitizers (PSs) into tumor cells to achieve selective imaging and on-demand photodynamic therapy (PDT) of tumors has provided a vital opportunity for precise cancer diagnosis and therapy. In this paper, we report a tumor targeting and adenosine triphosphate (ATP)-activatable nanophotosensitizer Apt-HyNP/BHQ2 by modifying hybrid micellar nanoparticles with both nucleolin-targeting aptamer AS1411 and quencher BHQ2 labeled ATP-binding aptamer BHQ2-ATP-apt. We demonstrated that both of the fluorescence emissions at 555 and 627 nm were quenched by BHQ2 in Apt-HyNP/BHQ2, resulting in low PDT capacity. After selective entry into tumor cells through nucleolin-mediated endocytosis, the high concentration of intracellular ATP could bind to BHQ2-ATP-apt and trigger Apt-HyNP/BHQ2 dissociation, leading to turning "on" both fluorescence and PDT. The "off-on" fluorescence emissions at both 555 and 627 nm were successfully applied for dual color fluorescence imaging of endogenous ATP levels and real-time monitoring of intracellular activation of Apt HyNP/BHQ2 in tumor cells. Moreover, imaging-guided precise PDT of tumors in living mice was also demonstrated, allowing for selective ablation of tumors without obvious side effects. This study highlights the potential of using a combination of tumor-targeting and ATP-binding aptamers to design ATP-activatable PSs for both fluorescence imaging and imaging-guided PDT of tumors in vivo. PMID- 29181975 TI - Alteration in MicroRNA Expression Governs the Nature and Timing of Cellular Fate Commitment. AB - In the central nervous system, the expression level of transcriptional repressor Hes1 (hairy and enhancer of split-1) tightly controls the alternative cell fate commitment during differentiation as well as the time required for such cellular transitions. A microRNA, miR-9, that interacts with Hes1 in a mutually antagonistic manner, influences both the process of lineage specification and timing of differentiation significantly, but the impact of the miR-9 in guiding these events still remains poorly understood. Here, we proposed a stochastic mathematical model of the miR-9/Hes1 double-negative feedback interaction network that at the outset shows how alternative cell fate such as quiescence, progenitor, and neuronal states can be accomplished through fine-tuning the Hes1 dynamics by altering the expression level of miR-9. The model simulations further foretell a correlated variation of the period of oscillation of Hes1, and the time delay observed between Hes1 mRNA and protein as the transcription rate of miR-9 increases during the neural progenitor state attainment. Importantly, the model simulations aided by the systematic sensitivity analysis predict that the timing of differentiation to the neuronal state crucially depends on the negative regulators (miR-9 and Hes6) of the Hes1.

AB - Low-temperature optoelectrical studies of perovskite solar cells using MAPbI3 and mixed-perovskite absorbers implemented into planar and mesoporous architectures reveal fundamental charge transporting properties in fully assembled devices operating under light bias. Both types of devices exhibit inverse correlation of charge carrier lifetime as a function of temperature, extending carrier lifetimes upon temperature reduction, especially after exposure to high optical biases. Contribution of bimolecular channels to the overall recombination process should not be overlooked because the density of generated charge surpasses trap-filling concentration requirements. Bimolecular charge recombination coefficient in both device types is smaller than Langevin theory prediction, and its mean value is independent of the applied illumination intensity. In planar devices, charge extraction declines upon MAPbI3 transition from a tetragonal to an orthorhombic phase, indicating a connection between the trapping/detrapping mechanism and temperature. Studies on charge extraction by linearly increasing voltage further support this assertion, as charge carrier mobility dependence on temperature follows multiple-trapping predictions for both device structures. The monotonously increasing trend following the rise in temperature opposes the behavior observed in neat perovskite films and indicates the importance of transporting layers and the effect they have on charge transport in fully assembled solar cells. Low-temperature phase transition shows no pattern of influence on thermally activated electron/hole transport.

AB - Transparent AgI-CuI heterojunctions with high rectifying diode behavior were prepared via vapor-phase iodization of metal thin films on transparent conducting oxide substrates. At room temperature, Ag and Cu metal thin films were quickly transformed into the transparent and well-crystallized beta-phase of AgI and the gamma-phase of CuI, respectively. The AgI and CuI films exhibited n-type and p type semiconductor properties, respectively, with wide band gaps. The heterojunctions were obtained by applying the CuI film to the AgI film in a sequential iodization process. AgI compounds generally have poor air-stability under light, making them suboptimal for use in electronic applications. Here, we used a CuI top layer to inhibit the photodecomposition of the AgI bottom layer, resulting in an air-stable and smooth AgI-CuI film. We also propose a simple patterning method for the AgI-CuI layer using selective decomposition of AgI without the need for lithography equipment or toxic chemicals. Although there is metal ion exchange between the two layers, each layer has a different chemical composition and crystal structure; therefore, the AgI-CuI heterojunction exhibits pn-diode behavior with a rectifying ratio of 9.4 * 104, which is comparable to that of other transparent pn-diodes. These findings open a new path for electronic application of AgI materials.

AB - In this study, three kinds of milk were treated with the beta-galactosidase Bgal1 3 (4 U/mL), resulting in 7.2-9.5 g/L galactooligosaccharides (GOS) at a lactose conversion of 90-95%. Then, Bgal1-3 was secreted from Pichia pastoris X33 under the direction of an alpha-factor signal peptide. After cultivation for 144 h in a flask culture with shaking, the extracellular activity of Bgal1-3 was 4.4 U/mL. Five more signal peptides (HFBI, apre, INU1A, MF4I, and W1) were employed to direct the secretion, giving rise to a more efficient signal peptide, W1 (11.2 U/mL). To further improve the secretion yield, recombinant strains harboring two copies of the bgal1-3 gene were constructed, improving the extracellular activity to 22.6 U/mL (about 440 mg/L). This study successfully constructed an engineered strain for the production of the beta-galactosidase Bgal1-3, which is a promising catalyst in the preparation of prebiotic-enriched milk.

AB - The well-defined heavy rare-earth ytterbium iodide complex 1 (L2YbI) has been successfully employed as an efficient catalyst for the hydroboration of a wide range of aldehydes and ketones with pinacolborane (HBpin) at room temperature. The protocol requires low catalyst loadings (0.1-0.5 mol %) and proceeds rapidly (>99% conversion in <10 min). Additionally, catalyst 1 shows a good functional group tolerance even toward the hydroxyl and amino moieties and displays chemoselective hydroboration of aldehydes over ketones under mild conditions.

AB - Early B cell factor 1 (EBF1) is one of the key transcription factors required for orchestrating B-cell lineage development. Although studies have shown that Ebf1 haploinsufficiency is involved in the development of leukemia, no study has been conducted that characterizes the global effect of Ebf1 heterozygosity on the proteome of pro-B lymphocytes. Here, we employ both data independent acquisition (DIA) and shotgun data dependent acquisition (DDA) workflows for profiling proteins that are differently expressed between Ebf1+/+ and Ebf1+/- cells. Both DDA and DIA were able to reveal the downregulation of the EBF1 transcription factor in Ebf1+/- pro-B lymphocytes. Further examination of differentially expressed proteins by DIA revealed that, similar to EBF1, the expression of other B-cell lineage regulators, such as TCF3 and Pax5, is also downregulated in Ebf1 heterozygous cells. Functional DIA analysis of differentially expressed proteins showed that EBF1 heterozygosity resulted in the deregulation of at least eight transcription factors involved in lymphopoiesis and the deregulation of key proteins playing crucial roles in survival, development, and differentiation of pro-B lymphocytes.

AB - A newly developed SPD (spiro-pyrrolidine) organocatalyst has been demonstrated to enable an asymmetric aza-Michael/Michael/aldol cyclization cascade, in which two six-membered rings (B/C) and three stereocenters have been constructed in a catalytic one-step process. It is so far the most efficient method for construction of hydrophenanthridine derivatives featuring high enantioselectivity. The trans- or cis-fused B/C-rings can be selectively assembled in a substrate-controlled manner. Moreover, this cascade could magnify to gram scale without loss of enanioselectivity.

The key compound in carbon carbon bond formation by magnesium-promoted reduction is ethyl trifluoroacetate, which has been rarely used as a fluorine-containing carbon source, especially to electron-deficient carbon atoms in organic synthesis. PMID- 29181984 TI - From Positive to Negative Zero-Field Splitting in a Series of Strongly Magnetically Anisotropic Mononuclear Metal Complexes. AB - A series of mononuclear [M(hfa)2(pic)2] (Hhfa = 1,1,1,5,5,5-hexafluoro-2,4 pentanedione; pic = 4-methylpyridine; M = FeII, CoII, NiII, ZnII) compounds were obtained and characterized. The structures of the complexes have been resolved by single-crystal X-ray diffraction, indicating that, apart from the zinc derivative, the complexes are in a trans configuration. Moreover, a dramatic lenghthening of the Fe-N distances was observed, whereas the nickel(II) complex is almost perfectly octahedral. The magnetic anisotropy of these complexes was thoroughly studied by direct-current (dc) magnetic measurements, high-field electron paramagnetic resonance, and infrared (IR) magnetospectroscopy: the iron(II) derivative exhibits an out-of-plane anisotropy (DFe = -7.28 cm-1) with a high rhombicity, whereas the cobalt(II) and nickel(II) complexes show in-plane anisotropy (DCo ~ 92-95 cm-1; DNi = 4.920 cm-1). Ab initio calculations were performed to rationalize the evolution of the structure and identify the excited states governing the magnetic anisotropy along the series. For the iron(II) complex, an out-of-phase alternating-current (ac) magnetic susceptibility signal was observed using a 0.1 T dc field. For the cobalt(II) derivative, the ac magnetic susceptibility shows the presence of two field-dependent relaxation phenomena: at low field (500 Oe), the relaxation process is beyond single-ion behavior, whereas at high field (2000 Oe), the relaxation of magnetization implies several mechanisms including an Orbach process with Ueff = 25 K and quantum tunneling of magnetization. The observation by MU-SQUID magnetization measurements of hysteresis loops of up to 1 K confirmed the single-ion-magnet behavior of the cobalt(II) derivative.

AB - Background Deep, high-grade bursal-sided supraspinatus tendon tears are sometimes preoperatively misinterpreted as full-thickness tears on shoulder magnetic resonance imaging (MRI). Purpose To determine the usefulness of disproportionate fluid sign for differentiating high-grade bursal-sided partial-thickness tears from full-thickness tears on conventional MRI. Material and Methods Preoperative MRIs of 198 patients with arthroscopically confirmed high-grade bursal-sided partial-thickness tears and full-thickness tears were independently reviewed by two readers on two occasions. The presence of high-grade bursal-sided partial thickness tears with a confidence level using a five-point grading scale was assessed based on tear depth alone and also in combination with disproportionate fluid sign, defined as a prominent subdeltoid or subacromial-subdeltoid bursal fluid distension with a relative paucity of effusion in the glenohumeral joint. The sensitivity, specificity, accuracy, and area under the receiver operating characteristic curve (AUC) were calculated, as well as inter-observer reliability. Results The disproportionate fluid sign was identified in 60/74 (81.2%) bursal-sided partial-thickness tears and 9/124 (7.5%) full-thickness tears. The sensitivity and accuracy of the diagnosis of bursal-sided tear were higher when disproportionate fluid sign was used in conjunction with the tear depth, compared with tear depth alone ( P < 0.001). There was excellent inter observer agreement for disproportionate fluid sign and deep bursal-sided tear. The AUCs were significantly higher in combination with disproportionate fluid sign. Conclusion The disproportionate fluid sign indicates the presence of a deep, high-grade bursal-sided partial-thickness tear, which can be misinterpreted as a full-thickness tear. Thus, it can provide greater diagnostic assistance to less-experienced radiologists and clinicians. PMID- 29181987 TI - New co-editor: Neuroradiology.

AB - Background The differences regarding categorization of thyroid nodules among different guidelines may affect the diagnostic performances and agreement among observers. Purpose To compare the diagnostic performances and agreements between observers with various degree of experience when applying different guidelines for stratifying thyroid nodules using suspicious ultrasonography (US) features. Material and Methods This retrospective study included 370 thyroid nodules (>=10 mm). Four observers, grouped as experienced and inexperienced, evaluated the US features and made final assessments according to the Kim criteria, Thyroid Imaging Reporting and Data System (TIRADS) by Kwak et al., and the 2015 American Thyroid Association (ATA) guideline. Diagnostic performances and agreements among the two groups were compared. Results The Kim criteria shows higher specificity with significantly lower sensitivity when compared to TIRADS and the 2015 ATA guideline (all P < 0.001), regardless of the level of experience. The experienced group showed significantly higher specificity with the Kim criteria and the 2015 ATA guideline compared to the inexperienced group ( P < 0.001), and the inexperienced group showed significantly higher sensitivity using the Kim criteria ( P = 0.002). The experienced group showed significantly higher agreement than the inexperienced group when using TIRADS while higher agreement was seen when using the 2015 ATA guideline for the inexperienced group. Agreement was not significantly different for the Kim criteria according to observer experience. Conclusion The diagnostic performances and agreements show significant differences in risk stratification of thyroid nodules according to the three guidelines using suspicious US features and the level of experience of the observer. PMID- 29181989 TI - Fourth update on CT angiography of coronary stents: in vitro evaluation of 24 novel stent types. AB - Background Non-invasive evaluation of coronary stent patency by coronary computed tomography angiography (cCTA) remains challenging. Multiple studies showed that CT technology but also individual stent design strongly influence the assessability of coronary stents by cCTA. Purpose To expand the available data on cCTA characteristics of coronary stents by 24 novel types to help interpreting examinations of patients after stent placement and selecting which stents are suitable for assessment by cCTA. Material and Methods Twenty-four novel coronary stents (17 cobalt-chromium, six stainless-steel, one platinum-chromium) were examined in a coronary phantom. Standard cCTA parameters with stent-specific algorithms were used. Image quality was quantified for each stent using established parameters (in-stent attenuation alteration and visible lumen diameter). Results Most stents (n = 14) showed lumen visibilities of 45-55%. No severe restriction of lumen visibility (>60%) was found. The majority of stents (n = 13) caused only small intraluminal attenuation deviations and no severe alterations (>20%) were found. When grouped by manufacturing material, no significant differences were found between cobalt-chromium and stainless-steel with identical mean visible diameters (1.52 +/- 0.17 mm vs. 1.52 +/- 0.13 mm) and comparable attenuation alterations (35.04 +/- 16.56 HU vs. 21.25 +/- 14.60 HU). The only platinum-chromium stent showed a smaller visible diameter (1.23 mm) and higher attenuation alteration (41.70 HU), but was also deemed to be assessable by cCTA. Conclusion All 24 novel evaluated stents are eligible for non-invasive evaluation by cCTA without significant differences between cobalt-chromium and stainless-steel stents. This updated catalogue of CT appearances of current coronary stents may serve as reference when taking care of patients with stents in need of coronary imaging.

AB - Injuries to the hypoglossal and vagus nerves are the most commonly reported injuries during carotid endarterectomy. While unilateral single nerve injury is usually well tolerated, bilateral or combined nerve injuries can pose a serious threat to life. This study aims to increase awareness of the inferior pharyngeal vein, which usually passes posterior to the internal carotid artery but sometimes crosses anterior to it. Injury to either or both hypoglossal and vagus nerves can occur during control of unexpected haemorrhage from the torn and retracted edges of the inferior pharyngeal vein. We recommend careful ligation and division of this vein. In addition, we observed in 9 (17.3%) of the 52 operations that the pharyngeal vein formed a triangle with the vagus and hypoglossal nerves when it passes anterior to the internal carotid artery. PMID- 29181994 TI - Urachal remnant causing umbilical in-drawing during micturition. AB - The urachus is a vestigial remnant of the allantois, which is normally obliterated during fetal life to become the median umbilical ligament, which runs between the urinary bladder and umbilicus in adults. Failure of obliteration leaves a tubular urachal remnant, which may present with disease. We report a unique case of a urachal remnant causing umbilical pain and in-drawing on micturition in a nine-year-old boy. There was no urine discharge from the umbilicus and in-drawing did not occur on defecation. His urinary stream was normal. High frequency ultrasonography revealed a thick band with a narrow, anechoic, fluid filled central channel. Exploration via an infraumbilical curvilinear incision identified a thick urachal band that could be traced to the dome of the bladder. This was excised flush with the bladder. The patient remains well at nine months following surgery with complete cessation of symptoms.

PMID- 29181995 TI - The effect of rectal washout on local recurrence following rectal cancer surgery. AB - Introduction Local recurrence after surgery for rectal cancer is associated with significant morbidity and debilitating symptoms. Intraoperative rectal washout has been linked to a reduction in local recurrence but there is no conclusive evidence. The aim of this study was to evaluate whether performing rectal washout had any effect on the incidence of local recurrence in patients undergoing anterior resection for rectal cancer in the context of the current surgical management. Methods A total of 395 consecutive patients who underwent anterior resection with or without rectal washout for rectal cancer between January 2003 and July 2009 at a high volume single institution were analysed retrospectively. A standardised process for performing washout was used and all patients had standardised surgery in the form of total mesorectal excision. Neoadjuvant and adjuvant therapy was used on a selected basis. Patients were followed up for five years and local recurrence rates were compared in the two groups. Results Of the 395 patients, 297 had rectal washout and 98 did not. Both groups were well matched with regard to various important clinical, operative and histopathological characteristics. Overall, the local recurrence rate was 5.3%. There was no significant difference in the incidence of local recurrence between the washout group (5.7%) and the no washout group (4.1%). Conclusions Among our cohort of patients, there was no statistical difference in the incidence of local recurrence after anterior resection with or without rectal washout. This suggests that other factors are more significant in the development of local recurrence.

We present a case of a choledochal cyst involving only the proximal cystic duct, and discuss the taxonomic and therapeutic challenges. There is a need for a clearly defined classification system for these cysts as they may be categorised as either type II or type VI cysts. The optimal treatment remains debatable, with some authors recommending a bilioenteric reconstruction owing to the wide cystic duct-bile duct junction. However, we suggest that a cholecystectomy should be performed with examination of the specimen and frozen section in case of any abnormality rather than upfront bile duct excision. In addition, given the rarity of this condition and the paucity of long-term data, we recommend meticulous follow-up for development of any malignancy.

PMID- 29181999 TI - The effect of non-steroidal anti-inflammatory drugs on severity of acute pancreatitis and pancreatic necrosis. AB - Introduction Acute pancreatitis (AP) is a common emergency presentation and can be disabling. There is significant morbidity and mortality associated with AP, and it places a considerable burden on the healthcare system. Non-steroidal anti inflammatory drugs (NSAIDs) have been shown to have a protective effect in some elective contexts. This retrospective study aimed to evaluate the effect of NSAIDs on the course of AP and the severity of the disease. Methods A retrospective analysis was carried out of 324 patients admitted as an emergency with a diagnosis of AP to two UK hospitals. Patients were divided into two groups: those already taking NSAIDs for other co-morbidities and those not taking NSAIDs. Variables compared included: admission to a high dependency or intensive care unit; pancreatic necrosis; pseudocyst development; need for surgery; serum inflammatory markers; modified early warning scores on days 1, 3 and 5; length of stay; and mortality. Results Patients not taking NSAIDs were more likely to have a C-reactive protein level of >=150mg/l (p=0.007). Patients in the NSAID group experienced less pancreatic necrosis (p=0.019) and lower rates of pseudocyst formation (p=0.010). Other variables showed no difference between the two groups, specifically length of stay and mortality. Conclusions Routine NSAID use may exert a protective effect on the development of AP, its severity, and complications. Therapeutic use of NSAIDs in acute presentations with pancreatitis should be further evaluated. PMID- 29182000 TI - Colossal pilomatrixoma. AB - We describe the largest reported case of pilomatrixoma in the literature. While pilomatrixomas typically present as small soft-tissue nodules of the head, neck and upper extremities, they can also present as much larger masses in atypical locations. When they present in their usual size, pilomatrixomas have typical imaging features and can be correctly diagnosed with imaging studies before histological confirmation. Their clinical and imaging diagnosis become challenging when they are very large, as in our case. A giant pilomatrixoma should also be considered for paediatric patients presenting with a large subcutaneous soft-tissue mass.

AB - A 73-year-old man was referred for surgical excision of a massive mediastinal and cervical liposarcoma following neoadjuvant chemotherapy. Surgery was performed via a cervical incision, sternotomy and right posterolateral thoracotomy. The tumour arose from the oesophagus, which underwent extensive dissection and was oversewn with pleura after tumour resection. Histology confirmed a completely excised grade 2 de-differentiated liposarcoma with complete macroscopic excision. The patient made an excellent recovery. Oesophageal liposarcomas are rare and, unlike in this case, often extend intraluminally, necessitating oesophagectomy. To our knowledge, this is the largest such tumour found in the literature. PMID- 29182002 TI - Acute hand injury splinting - the good, the bad and the ugly. AB - Injuries to the hand comprise 20% of all emergency department attendances, with an estimated annual treatment cost of over L100 million in the UK. The initial assessment and management of hand injuries is usually undertaken by junior staff, many of whom have little or no training or experience in splinting hand fractures. In the Department of Orthopaedic Hand Surgery, Morriston Hospital, we regularly observe patients presenting to the specialist hand fracture clinics having had initial management that shows no appreciation for the treatment objectives or the safe positions for splinting. This article aims to provide guidance for frontline staff on the management of hand fractures, with particular emphasis on the appropriate nonoperative care to avoid any unnecessary morbidity.

PMID- 29182003 TI - Modification, validation and implementation of a protocol for post-thyroidectomy hypocalcaemia. AB - Introduction The management of post-thyroidectomy hypocalcaemia should facilitate early discharge, and reduce risks of hypocalcaemia, readmission and treatment related hypercalcaemia. This paper describes the implementation, evaluation and revision a protocol for the optimal management of this condition. Methods Day 1 parathyroid hormone (PTH) measurements in addition to calcium measurements were commenced following review of the unit's outcomes and literature on post thyroidectomy hypocalcaemia. Outcomes from a three-year cohort of patients undergoing thyroid surgery helped amend this protocol (revision 1) to reduce biochemical tests, stipulate the need, nature and dose of vitamin D/calcium supplements, and encourage early discharge. This was further validated over seven months to assess compliance, episodes of hyper and/or hypocalcaemia after discharge, readmissions and need for treatment changes. Further revisions were made (revision 2) and implemented. Results The temporary and long-term postoperative hypocalcaemia rates were 29.1% and 3.2% respectively. Repeat calcium measurements on the first day altered management in only 1.4% of cases. The revised protocol was adhered to in 90% of cases. One patient had hypocalcaemia (due to non-compliance) and one had hypercalcaemia. Revision 2 involved reducing the dose of calcium. Conclusions This is a good example of a unit protocol for post-thyroidectomy hypocalcaemia being developed and modified on the basis of the literature and local experience. Day 1 PTH and calcium levels determine the need for treatment and frequency of follow-up visits, facilitate early discharge, reduce risk of over and/or undertreatment, and are good indicators of permanent hypocalcaemia.

AB - AIM: The aim of this study was to explore the relationship between IL-1beta-31T/C polymorphism and serum levels of IL-1beta and the risk of acute heart failure (AHF). METHODS: A total of 320 dyspnea patients (160 with AHF and 160 without AHF) and 100 healthy subjects were included in this study. IL-1beta genotyping was performed by PCR-restriction fragment length polymorphism technique. RESULTS: Concentration of IL-1beta was significantly higher in patients with heart failure (HF) compared with non-HF and control groups. Results of the distribution of IL 1beta-31T/C genotypes and allele frequencies did not show any significant difference between the three groups. Serum levels of IL-1beta were found to be higher among TT genotype than TC and CC genotype. CONCLUSION: IL-1beta levels may be useful for the evaluation of diagnosis in acutely decompensated HF. PMID- 29182006 TI - Intimacy, intercourse and adjustments: Experiences of sexual life of a group of people with physical disabilities in South Africa. AB - There is a growing recognition of the sexual and reproductive rights of people with disabilities, and since the World Health Organisation's World Report on Disability, increased international attention has been given to these issues. Past research, however, suggests that this group encounter barriers to sexual and reproductive rights, which are both physical and attitudinal. Against this backdrop, this article employs a sequential mixed qualitative methodology to explore the practical and subjective experiences of 13 people with physical disabilities in South Africa, with regard to their sexual lives and experiences of sexuality. These experiences were marked by concerns about their 'fitness' as sexual beings and indicated that social forces were key in shaping their expectations for their own sexual life.

AB - There are unique methodological challenges to studying and assessing recovery in myalgic encephalomyelitis and chronic fatigue syndrome. This study explored these challenges through interviewing 13 physicians who treat myalgic encephalomyelitis and chronic fatigue syndrome. Our deductive thematic analysis produced four themes to consider when approaching recovery: lifespan differences in the illness experience; the heterogeneity of myalgic encephalomyelitis and chronic fatigue syndrome-case definitions, etiological stance, and misdiagnosis; patient follow up and selection bias; and assessment logistics. We discuss how researchers and clinicians can use these considerations when working with patients, drafting recovery criteria, and interpreting treatment outcomes.

AB - AIM: To evaluate PlncRNA-1, TUG1 and FAM83H-AS1 gene expression and their possible role as a biomarker in gastric cancer (GC) progression. PATIENTS & METHODS: Long noncoding RNA expressions and clinicopathological characteristics were assessed in 70 paired GC tissues. Furthermore, corresponding data from 318 GC patients were downloaded from The Cancer Genome Atlas database. RESULTS: Expression of PlncRNA-1 and TUG1 were significantly upregulated in GC tumoral tissues, and significantly correlated with clinicopathological characters. However, FAM83H-AS1 showed no consistently differential expression. The expression of these three long noncoding RNAs was significantly higher in The Cancer Genome Atlas tumoral tissues. CONCLUSION: In conclusion, PlncRNA-1 and TUG1 genes may play a critical role in GC progression and may serve as potential diagnostic biomarkers in GC patients. PMID- 29182009 TI - Systematic Changes in Preference for Schedule-Thinning Arrangements as a Function of Relative Reinforcement Density. AB - We treated destructive behavior maintained by both social-positive (i.e., access to tangibles) and social-negative (i.e., escape from demands) reinforcement in an individual diagnosed with autism spectrum disorder using functional communication training (FCT). We then thinned the schedule of reinforcement for the tangible function using a multiple schedule (mult FCT) and later thinned the availability of escape using a chained schedule (chain FCT). Both treatments proved effective at maintaining functional communicative responses while decreasing destructive behavior to near-zero levels. In addition, treatment effects maintained when we rapidly thinned mult FCT to the terminal schedule. Throughout chain-FCT schedule thinning, we assessed client preference for each schedule-thinning arrangement (mult FCT or chain FCT) using a concurrent-chains procedure. Client preference reliably shifted from chain FCT to mult FCT as the response requirement increased and the proportion of session spent in reinforcement began to favor mult FCT. We discuss the clinical implications of these findings.

AB - Enzymatic browning affects the sensory and nutritional quality of fresh-cut apples and limits their shelf-life. Yerba mate ( Ilex paraguariensis), a plant widely consumed in South America as an infusion, could potentially be used in minimally processed fruits and vegetables as a natural additive to prevent browning, due to its high content of phenolic compounds with antioxidant capacity. The effects of the concentrations of ascorbic acid, citric acid, and yerba mate in an aqueous dipping solution on the instrumental color parameters, antioxidant capacity, and sensory quality of "Granny Smith" fresh-cut apples were modeled and the solution was optimized to obtain treated apples with maximum antioxidant capacity and minimum browning, without affecting the natural flavor of the fruits. The optimal composition obtained (1.2% yerba mate + 0.9% citric acid + 1.0% ascorbic acid) increased the antioxidant capacity of the apples by 36%. The sensory acceptability test carried out on the "Granny Smith" fresh-cut apples treated with the optimal dipping solution showed that more than 78% of the surveyed consumers liked the color, flavor, and texture of the apples. PMID- 29182011 TI - Mobile Technology-Based Real-Time Teleotolaryngology Care Facilitated by a Nonotolaryngologist Physician in an Adult Population. AB - OBJECTIVES: Telehealth can improve access to specialist care. Very few reports of the use of smartphones for teleotolaryngology exist. The objective of this study is to evaluate the use of mobile teleotolaryngology facilitated by a nonotolaryngologist physician. METHODS: A prospective study in adult patients attending a general otolaryngology outpatient clinic. The telehealth encounter with a remote otolaryngologist was facilitated by a final-year medical student simulating a general physician prior to the scheduled visit. The patient and the remote otolaryngologist rated their satisfaction with the encounter. The remote otolaryngologist formulated a diagnosis and rated the level of certainty of this diagnosis. Diagnoses from the telehealth encounter and the face-to-face encounter were compared. RESULTS: Forty-eight patients with an average age of 42.5 years participated in this study. In 79.2% of the consultations, there was concordance between the diagnoses. The average patient and remote otolaryngologist satisfaction with the encounter was 9.5 +/- 0.9 and 8.7 +/- 1.3, respectively. Twenty-four of the 48 visits (50%) were defined as unnecessary. In the otology group, concordance rates and rates of preventable visits were highest. CONCLUSIONS: Synchronous telehealth consultations, facilitated by a general physician, can be an alternative to visiting a general otolaryngology clinic, especially for otologic patients.

We report on the first 21,550 participants with relevant phenotypic data, 7,458 of whom have been genotyped genome-wide. Measures of crystallized and fluid intelligence reflected a two-dimensional latent ability space, with items demonstrating adequate item level characteristics. The Big Five Inventory questionnaire revealed the expected five-factor model of personality. Cognitive measures predicted educational attainment over and above personality characteristics, as expected. We found that a genome-wide polygenic score of educational attainment predicted educational level, accounting for 4%, 4%, and 2.7% of the variance in educational attainment, verbal reasoning, and spatial reasoning, respectively. In summary, the online cognitive measures in Genes for Good appear to perform adequately and demonstrate expected associations with personality, education, and an education-based polygenic score. Results indicate that online cognitive assessment is one avenue to accumulate large samples of individuals for genetic research of cognitive ability. PMID- 29182013 TI - Friend or foe? Mitochondria as a pharmacological target in cancer treatment. AB - Mitochondria have acquired numerous functions over the course of evolution, such as those involved in controlling energy production, cellular metabolism, cell survival, apoptosis and autophagy within host cells. Tumor cells can develop defects in mitochondrial function, presenting a potential strategy for designing selective anticancer therapies. Therefore, cancer has been the main focus of recent research to uncover possible mitochondrial targets for therapeutic benefit. This comprehensive review covers not only the recent discoveries of the roles of mitochondria in cancer development, progression and therapeutic implications but also the findings regarding emerging mitochondrial therapeutic targets and mitochondria-targeted agents. Current challenges and future directions for developments and applications of mitochondrial-targeted therapeutics are also discussed. PMID- 29182014 TI - Emodin attenuates cell injury and inflammation in pancreatic acinar AR42J cells. AB - The study was intended to investigate the protective effects of emodin against cell injury and inflammation in AR42J cells. We determined trypsin and lipase activity, intracellular ROS and MMP using specific assay kits. The related protein expression and TNF-alpha and IL-6 in the medium were assayed by Western blot and ELISA kits. Results showed that emodin could protect AR42J cells against cell injury caused by cerulein and lipopolysaccharide which were possibly associated with inhibition of mitochondrial damage, ROS production, and then significantly inhibited ROS-mediated pathway, and ameliorated pancreatic cells injury by depleting the levels of inflammatory cytokines. PMID- 29182015 TI - Toward the clinical use of circulating biomarkers predictive of bone union. AB - Current methods for diagnosis of bone healing after treatment of trauma injuries rely on clinical findings and the use of imaging methodologies that provide conclusive results but only at mid/long-term post-intervention. In this Perspective we present and discuss incipient evidence on biomarkers that may serve for monitoring the progression of bone healing as well as predicting eventual nonunion outcomes. PMID- 29182017 TI - Compressive Detection of Highly Overlapped Spectra Using Walsh-Hadamard-Based Filter Functions. AB - In the chemometric context in which spectral loadings of the analytes are already known, spectral filter functions may be constructed which allow the scores of mixtures of analytes to be determined in on-the-fly fashion directly, by applying a compressive detection strategy. Rather than collecting the entire spectrum over the relevant region for the mixture, a filter function may be applied within the spectrometer itself so that only the scores are recorded. Consequently, compressive detection shrinks data sets tremendously. The Walsh functions, the binary basis used in Walsh-Hadamard transform spectroscopy, form a complete orthonormal set well suited to compressive detection. A method for constructing filter functions using binary fourfold linear combinations of Walsh functions is detailed using mathematics borrowed from genetic algorithm work, as a means of optimizing said functions for a specific set of analytes. These filter functions can be constructed to automatically strip the baseline from analysis. Monte Carlo simulations were performed with a mixture of four highly overlapped Raman loadings and with ten excitation-emission matrix loadings; both sets showed a very high degree of spectral overlap. Reasonable estimates of the true scores were obtained in both simulations using noisy data sets, proving the linearity of the method. PMID- 29182016 TI - Improved antifouling properties of photobioreactors by surface grafted sulfobetaine polymers. AB - To improve the antifouling (AF) properties of photobioreactors (PBR) for microalgal cultivation, using trihydroxymethyl aminomethane (tris) as the linking agent, a series of polyethylene (PE) films grafted with sulfobetaine (PE-SBMA) with grafting density ranging from 23.11 to 112 MUg cm-2 were prepared through surface-initiated atom transfer radical polymerization (SI-ATRP). It was found that the contact angle of PE-SBMA films decreased with the increase in the grafting density. When the grafting density was 101.33 MUg cm-2, it reached 67.27 degrees . Compared with the PE film, the adsorption of protein on the PE-SBMA film decreased by 79.84% and the total weight of solid and absorbed microalgae decreased by 54.58 and 81.69%, respectively. Moreover, the transmittance of PE SBMA film recovered to 86.03% of the initial value after cleaning, while that of the PE film recovered to only 47.27%. The results demonstrate that the AF properties of PE films were greatly improved on polySBMA-grafted surfaces. PMID- 29182018 TI - Structure-activity relationships of hydroxamate-based histone deacetylase-8 inhibitors: reality behind anticancer drug discovery. AB - The pan-histone deacetylase (HDAC) inhibitors comprise a fish-like structural orientation where hydrophobic aryl- and zinc-binding groups act as head and tail, respectively of a fish. The linker moiety correlates the body of the fish linking head and tail groups. Despite these pan-HDAC inhibitors, selective HDAC-8 inhibitors are still in demand as a safe remedy. HDAC-8 is involved in invasion and metastasis in cancer. This review deals with the rationale behind HDAC-8 inhibitory activity and selectivity along with detailed structure-activity relationships of diverse hydroxamate-based HDAC-8 inhibitors. HDAC-8 inhibitory potency may be increased by modifying the fish-like pharmacophoric features of such type of pan-HDAC inhibitors. This review may provide a preliminary basis to design and optimize new lead molecules with higher HDAC-8 inhibitory activity. This work may surely enlighten in providing useful information in the field of target-specific anticancer therapy. PMID- 29182019 TI - Pain and Function Following Revision Cubital Tunnel Surgery. AB - BACKGROUND: The purpose of this study was to determine pain and functional outcomes following revision cubital tunnel surgery and to identify predictors of poor postoperative outcome. METHODS: A retrospective cohort study was conducted of all patients undergoing revision cubital tunnel surgery over a 5-year period at a high-volume peripheral nerve center. Intraoperative findings, demographic and injury factors, and outcomes were reviewed. Average pain, worst pain, and impact of pain on self-perceived quality of life were each measured using a 10-cm visual analog scale (VAS). Function was evaluated using pinch and grip strength, as well as the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. Differences in preoperative and postoperative pain, strength, and DASH were analyzed using nonparametric tests. Predictors of postoperative average pain were evaluated using odds ratios and linear regression analyses. RESULTS: The final cohort consisted of 50 patients (mean age: 46.3 +/- 12.5 years; 29 [68%] male) undergoing 52 revision ulnar nerve transpositions (UNTs). Pain VAS scores decreased significantly following revision UNT. Strength and DASH scores demonstrated nonsignificant improvements postoperatively. Worse preoperative pain and greater than 1 prior cubital tunnel procedure were significant predictors of worse postoperative average pain VAS scores. CONCLUSIONS: Patients can and do improve following revision cubital tunnel surgery, particularly as it relates to pain. Intraoperative findings during the revision procedure suggest that adherence to specific principles in the primary operation is key to prevention of secondary cubital tunnel syndrome. PMID- 29182020 TI - New cycloartanes and new iridoids from Dolichandrone spathacea collected in the mangrove forest of Soc Trang province, Vietnam. AB - Two new cycloartanes, named dolichandrone A (1) and dolichandrone B (2), as well as two new iridoids, named [6-O-[(E)-4-methoxycinnamoyl]-1beta-hydroxy dihydrocatalpolgenin (3) and 6-O-[(E)-4-methoxycinnamoyl]-1alpha-hydroxy dihydrocatalpolgenin (4), together with four known iridoids (5-8), were isolated from the leaves and barks of Dolichandrone spathacea. Their structures were elucidated by means of extensive analysis of their HRESIMS, 1D and 2D NMR spectroscopic data. All of these compounds have been isolated for the first time from this plant. Compounds 1, 2, 5, and 7 were evaluated for their cytotoxic activity in vitro against four human cancer cell lines KB, Lu, HepG2, and MCF7. The results showed that only compound 2 exhibited a good cytotoxicity against KB cell line with IC50 of 18.77 MUM. PMID- 29182021 TI - Injuries Depicted in Sport-Related Films. AB - The perception that children and adolescents have of injuries may be influenced by their depiction in sport-related films. The objective of this study was to determine the depiction of injuries in a select number of sport-related films. Forty-four films were analyzed. Injury category, on-the-field management, and long-term management were determined for each injury. Major injuries were defined as injuries requiring prompt intervention and immediate discontinuation of sport participation. A total of 49 injuries were depicted, categorized as fracture (n = 11), contusion (n = 10), brain concussion (n = 8), muscle cramps (n = 5), laceration/abrasion (n = 4), ligamentous knee injury (n = 4), shoulder dislocation (n = 2), rotator cuff injury (n = 2), ankle sprain (n = 2), and unspecified injury (n = 1). Of the 38 (78%) injuries considered major, immediate return to the game was the disposition for 13 injuries (34%). Pediatric health care providers, coaching staff, and parents should stress the importance of injury recognition/disclosure and realistic expectations for rehabilitation to pediatric athletes. PMID- 29182022 TI - Persistent Perianal Rash in a Young Boy. PMID- 29182023 TI - PDGFRbeta-specific affibody-directed delivery of a photosensitizer, IR700, is efficient for vascular-targeted photodynamic therapy of colorectal cancer. AB - Vascular-targeted photodynamic therapy (PDT) is an important strategy for cancer therapy. Conventional vascular-targeted PDT has been achieved by passive photosensitizer (PS) delivery, which involves a high risk of adverse effects. Active PS delivery is urgently required for vascular-targeted PDT. Although endothelial cells and pericytes are major cellular components of tumor blood vessels, little attention has been paid to pericyte-targeted PDT for cancer therapy. PDGFRbeta is abundantly expressed in the pericytes of various tumors. In this experiment, a dimeric ZPDGFRbeta affibody with a 0.9 nM affinity for PDGFRbeta was produced. The ZPDGFRbeta affibody showed PDGFRbeta-dependent pericyte binding. Intravenously injected ZPDGFRbeta affibody was predominantly distributed on pericytes and thus accumulated in LS174T tumor grafts. The conjugate of the ZPDGFRbeta affibody and IR700 dye, i.e. ZIR700, bound to PDGFRbeta+ pericytes but not to PDGFRbeta- LS174T tumor cells. Accordingly, ZIR700-mediated PDT in vitro induced the death of pericytes but not of LS174T tumor cells. In mice bearing LS174T tumor grafts, ZIR700-mediated PDT damaged tumor blood vessels, thus inducing tumor destruction by intensifying tissue hypoxia. The average mass of tumor grafts administered with ZIR700-mediated PDT was approximately 20-30% of that of the control, indicating that pericyte targeted PDT is efficient for cancer therapy. In addition, ZIR700-mediated PDT increased the tumor uptake of TNF-related apoptosis-inducing ligand (TRAIL) injected post-illumination. Consequently, combination therapy of ZIR700-mediated PDT and TRAIL showed greater tumor suppression than ZIR700-mediated PDT- or TRAIL based monotherapy. These results demonstrated that active vascular-targeted PDT could be achieved by using ZPDGFRbeta affibody-directed delivery of PS. PMID- 29182024 TI - First nationwide survey on systemic wild-type ATTR amyloidosis in Japan. AB - OBJECTIVE: A nationwide survey on systemic wild-type ATTR (ATTRwt) amyloidosis was conducted to elucidate the frequency, clinical picture and possible diagnostic issues of ATTRwt amyloidosis in Japan. METHODS: A questionnaire was sent to 4629 clinical departments across Japan. A total of 2341 (50.6%) responses were returned completed for further analysis. RESULTS: Fifty-one patients with ATTRwt amyloidosis (82% male) were identified between January 2012 and December 2014. The study subjects were identified in 11 departments at 10 institutes. The mean age of onset and diagnosis were 71.6 and 73.6 years, respectively. The main clinical findings were cardiac failure (76%), cardiac conduction defects/arrhythmia (59%), renal dysfunction (49%), carpal tunnel syndrome (45%) and spinal canal stenosis (22%). CONCLUSIONS: ATTRwt amyloidosis is diagnosed in a limited number of institutes in Japan and is therefore considered to be underdiagnosed. PMID- 29182025 TI - VEGF-mediated tight junctions pathological fenestration enhances doxorubicin loaded glycolipid-like nanoparticles traversing BBB for glioblastoma-targeting therapy. AB - The existence of blood-brain barrier (BBB) greatly hindered the penetration and accumulation of chemotherapeutics into glioblastoma (GBM), accompany with poor therapeutic effects. The growth of GBM supervene the impairment of tight junctions (TJs); however, the pathogenesis of BBB breakdown in GBM is essentially poorly understood. This study found that vascular endothelial growth factor (VEGF) secreted by GBM cells plays an important role in increasing the permeability of BBB by disrupting endothelial tight junction proteins claudin-5 and thus gave doxorubicin (DOX)-loaded glycolipid-like nanoparticles (Ap CSSA/DOX), an effective entrance to brain tumor region for GBM-targeting therapy. In addition, VEGF downregulates the expression of claudin-5 with a dose-dependent mode, and interfering with the VEGF/VEGFR pathway using its inhibitor axitinib could reduce the permeability of BBB and enhance the integrity of the barrier. Ap CSSA/DOX nanoparticles showed high affinity to expressed low-density lipoprotein receptor-related proteins 1 (LRP1) in both BBB and GBM. And BBB pathological fenestration in GBM further exposed more LRP1 binding sites for Ap-CSSA/DOX nanoparticles targeting to brain tumor, resulting in a higher transmembrane transport ratio in vitro and a stronger brain tumor biodistribution in vivo, and finally realizing a considerable antitumor effect. Overall, taking advantage of BBB pathological features to design an appropriate nanodrug delivery system (NDDS) might provide new insights into other central nervous system (CNS) diseases treatment. PMID- 29182026 TI - Extensor Carpi Ulnaris Tenodesis Versus No Stabilization After Wide Resection of Distal Ulna Giant Cell Tumors. AB - BACKGROUND: The necessity of stabilizing the residual ulnar stump after distal ulna tumor resection remains controversial. The authors retrospectively compared the outcome of patients who underwent wide resection of distal ulna giant cell tumors (GCTs) and reconstruction with tenodesis of the extensor carpi ulnaris (ECU) or without reconstruction. METHODS: Between 2007 and 2015, 9 patients (6 females, 3 males; mean age, 36.8 years; range, 24-65 years) who underwent distal ulna resection for GCT of bone were retrospectively reviewed. The mean resection length was 8.1 cm. Five patients had no reconstruction, whereas 4 patients had stabilization of the ulnar stump using ECU tenodesis. With a mean follow-up of 3.6 years (2-9 years), the functional outcome using the quick Disability of Arm, Shoulder and Hand (DASH) score; Musculoskeletal Tumor Society score and grip strength; as well as the oncological outcome were evaluated. RESULTS: Musculoskeletal Tumor Society functional scores were more than 24 in 7 patients and 20 to 24 in 2 patients (mean, 27.6 or 92%). Quick DASH scores ranged from 0 to 27.3 (mean, 11.1). In both groups, similar scores were observed ( P > .5). No patient had instability or pain related to the stump. There was no ulnar translation or subluxation of the radiocarpal joint. Grip strength in the operated hand, controlled for handedness, was 11% less than in the contralateral hand, although there was no difference between groups ( P > .4). All patients were disease-free at the latest follow-up. CONCLUSIONS: The distal ulna may be widely resected with or without stabilization of the residual ulnar stump, yielding satisfactory local disease control and functional outcome. PMID- 29182027 TI - How development of blood biomarkers could benefit prehospital management of acute stroke. PMID- 29182028 TI - Altered expression of lysophosphatidic acid receptors, in association with the synthesis of estrogens and androgens in type 1 endometrial cancer biology. AB - To establish association between two main lysophosphatidic acid (LPA) receptors (LPAR2 and LPAR1) with the synthesis of estrogens and androgens in type-1 endometrial carcinoma (EC), we evaluated correlation of LPARs expression with expression of steroid 5 alpha-reductase 2 - aromatase (SRD5A2), or cytochrome P450 family 19 subfamily A member 1-5alpha-reductase (CYP19A1) in EC. Moreover, we aimed to investigate SRD5A2 and CYP19A1 expression in type 1 endometrial cancer and normal endometrium with its correlation to selected clinicopathological features. The studied cancerous samples showed higher CYP19A1 and SRD5A2 expression comparing to normal endometria. We also documented positive correlations between LPAR1 and LPAR2 with responsible for proliferation SRD5A2 in EC tissue which suggests that intratumoral estrogen metabolism and synthesis are pivotal in endometrial carcinoma progression, with the involvement of LPA in this process. However, positive correlation between CYP19A1 and LPAR1 accounts for supporting role of LPA acting via LPAR1 in intratumoral DHT concentration and the ethiology of endometrial cancer progression. Also, owing to the highest expression of LPARs, CYP19A1 and SRD5A2 as well as their association with depth of myoinvasion and FIGO stage LPAR2 and LPAR1 seem to be the efficient candidate prognostic markers in the individual, targeted therapies for EC. PMID- 29182029 TI - Strategies to keep working among workers with common mental disorders - a grounded theory study. AB - PURPOSE: Most people with common mental disorders (CMDs) are employed and working, but few studies have looked into how they manage their jobs while ill. This study explores workers' experiences of strategies to keep working while suffering from CMDs. METHODS: In this grounded theory study, we interviewed 19 women and eight men with depression or anxiety disorders. They were 19-65 years old and had different occupations. Constant comparison method was used in the analysis. RESULTS: We identified a core pattern in the depressed and anxious workers' attempts to sustain their capacities, defined as Managing work space. The core pattern comprised four categories describing different cognitive, behavioral, and social strategies. The categories relate to a process of sustainability. Two categories reflected more reactive and temporary strategies, occurring mainly in the onset phase of illness: Forcing the work role and Warding off work strain. The third category, Recuperating from work, reflected strategies during both onset and recovery phases. The fourth category, Reflexive adaptation, was present mainly in the recovery phase and involved reflective strategies interpreted as more sustainable over time. CONCLUSIONS: The results can deepen understanding among rehabilitation professionals about different work-related strategies in depressed and anxious workers. Increased awareness of the meaning and characteristics of strategies can inform a person-oriented approach in rehabilitation. The knowledge can be used in clinical encounters to reflect together with the patient, exploring present options and introducing modifications to their particular work and life context. Implications for rehabilitation Self-managed work functioning in common mental disorders involves diverse strategies. Strategies interpreted as sustainable over time, seem to be reflective in the sense that the worker consciously applies and adapts the strategies. However, at the onset of illness, such reflection is difficult to develop as the worker might not want to realize their reduced functioning. Rehabilitation professionals' awareness of different strategies can facilitate a person-centered approach and understanding of the vocational rehabilitation process. PMID- 29182030 TI - Biomarkers of ocular surface disease using impression cytology. AB - Impression cytology (IC) is a technique which permits the retrieval of the outermost layer of ocular surface cells via the use of various types of filters. It is a minimally invasive method of evaluating human conjunctival epithelial cell morphology in the diagnosis of dry eye disease, a common and distressing disorder associated with ageing, contact lens wear, autoimmune disorders and refractive (LASIK) surgery. IC may also be utilized in the diagnosis of other ocular diseases, such as keratoconus and thyroid orbitopathy. More recently, IC has been utilized for the subsequent investigation of gene and protein expression of conjunctival cells in order to identify novel diagnostic biomarkers and to further our understanding of the mechanisms underlying ocular surface disease. This review will therefore examine the literature concerning the role of IC in identifying cellular markers of eye disease, systemic diseases with ocular involvement and potential novel therapeutic targets. PMID- 29182031 TI - Recent developments in d-alpha-tocopheryl polyethylene glycol-succinate-based nanomedicine for cancer therapy. AB - Cancer remains an obstacle to be surmounted by humans. As an FDA-approved biocompatible drug excipient, d-alpha-tocopheryl polyethylene glycol succinate (TPGS) has been widely applied in drug delivery system (DDS). Along with in-depth analyses of TPGS-based DDS, increasingly attractive results have revealed that TPGS is able to act not only as a simple drug carrier but also as an assistant molecule with various bio-functions to improve anticancer efficacy. In this review, recent advances in TPGS-based DDS are summarized. TPGS can inhibit P glycoprotein, enhance drug absorption, induce mitochondrial-associated apoptosis or other apoptotic pathways, promote drug penetration and tumor accumulation, and even inhibit tumor metastasis. As a result, many formulations, by using original TPGS, TPGS-drug conjugates or TPGS copolymers, were prepared, and as expected, an enhanced therapeutic effect was achieved in different tumor models, especially in multidrug resistant and metastatic tumors. Although the mechanisms by which TPGS participates in such functions are not yet very clear, considering its effectiveness in tumor treatment, TPGS-based DDS appears to be one of the best candidates for future clinical applications. PMID- 29182032 TI - Squamous Cell Carcinoma of the Bulbar Urethra Accompanied by Lichen Sclerosus: A Case Report. AB - Squamous cell carcinoma (SCC) of the bulbar urethra accompanied by lichen sclerosus (LS) is rarely reported. This study reports the case of a 56-year-old man with urethral squamous cell carcinoma (USCC) accompanied by a long history of genital LS. The man presented with a painful perineal mass and had a long-term history of urethral strictures and urethral dilatation. The patient developed a periurethral abscess that expanded to the perineum and formed an urethrocutaneousperineal fistula. An organ-sparing perineal resection and fistulectomy was performed according to the patient's wishes. During the operation, residue-like pus mixed with necrotic tissues drained out. A section of the prepuce and the necrotic tissues were sent for histological analysis. Hematoxylin and eosin (HE) staining of the excised prepuce revealed classical LS. HE and immunohistochemical (IHC) staining of the necrotic tissues showed well differentiated USCC. IHC staining showed the USCC to be positive for P53 and Ki 67 and negative for P16, suggesting the USCC was probably associated with LS. The patient received high-dose chemotherapy and radiation therapy and died 10 months after surgery. PMID- 29182033 TI - Influence of physical activity on the health-related quality of life of young adults with and without autism spectrum disorder. AB - BACKGROUND: Health-related quality of life constructs has been used to understand the multiple dimensions (i.e., physical health, psychological, environment and social relationships) that affect a person's health status. In order to improve health-related quality of life for young adults, it is important to understand the factors that influence each dimension. The purpose of this paper was to examine the influence of the presence of autism spectrum disorder and physical activity on the multiple domains of health-related quality of life for young adults. METHODS: Three-hundred and twenty participants, including young adults with ASD, completed a questionnaire about their physical activity and health related quality of life. RESULTS: Five multiple regressions revealed that the presence of autism spectrum disorder significantly predicted overall health related quality of life, the physical health domain, psychological domain, and the environment domain. Additionally, physical activity significantly predicted each domain and overall health-related quality of life regardless of the presence of autism spectrum disorder. CONCLUSION: Practitioners should recognize the limitations that individuals with autism spectrum disorder may experience regarding their health-related quality of life, and utilize physical activity as a tool for improving health-related quality of life. Implications for Rehabilitation In order to address an individual's overall health, practitioners must consider multiple dimensions of health-related quality of life. Autism spectrum disorders influence how people perceive multiple dimensions of their health. Physical activity is a tool for improving perceptions of the multiple dimensions of health for individuals with and without autism spectrum disorders. PMID- 29182035 TI - Oral Health of Children With Attention Deficit Hyperactivity Disorder: Systematic Review and Meta-Analysis. AB - OBJECTIVE: This systematic review investigated the oral health of children with ADHD. METHOD: A structured search strategy was performed on five electronic databases: SCOPUS, Web of Science, COCHRANE, PubMed, and PsychInfo. Studies were included in the review if they reported clinical oral health outcomes on a population diagnosed with ADHD under the age of 18 years old. Qualitative and quantitative analysis was performed on pooled prevalence and mean/median values for caries, trauma, periodontal problems, and tooth wear. RESULTS: Twenty-seven effective articles were reviewed by two calibrated assessors. Meta-analysis of the results found higher mean number of decayed surfaces, plaque index, and trauma prevalence among children with ADHD. CONCLUSION: Children with ADHD show increased risk for caries and traumatic dental injuries, and may have poorer oral hygiene compared with children without ADHD. More awareness among clinicians would promote better caries- and trauma-preventive advice and management. PMID- 29182036 TI - The Stanmore Nursing Assessment of Psychological Status (SNAPS): not just for spinal cord injury rehabilitation? AB - Spinal cord injury is an uncommon condition, potentially causing a wide range of consequences and requiring specialist rehabilitation to optimize health, activity and participation. Early psychological response to injury and relations with staff, as well as family, may set the foundations for long-term emotional adjustment, healthcare utilization and quality of life. The Stanmore Nursing Assessment of Psychological Status has been developed at the London Spinal Cord Injury Centre to empower nurses to adopt a consistently empathic approach to patient care, as part of a comprehensive range of rehabilitation team skills. Its use in other spinal cord injury centers and a broader range of clinical environments (hospital and community) should therefore be considered. PMID- 29182034 TI - Molecular Imaging and Radionuclide Therapy of Melanoma Targeting the Melanocortin 1 Receptor. AB - Melanoma is a deadly disease at late metastatic stage, and early diagnosis and accurate staging remain the key aspects for managing melanoma. The melanocortin 1 receptor (MC1 R) is overexpressed in primary and metastatic melanomas, and its endogenous ligand, the alpha-melanocyte-stimulating hormone (alphaMSH), has been extensively studied for the development of MC1 R-targeted molecular imaging and therapy of melanoma. Natural alphaMSH is not well suited for this purpose due to low stability in vivo. Unnatural amino acid substitutions substantially stabilized the peptide, while cyclization via lactam bridge and metal coordination further improved binding affinity and stability. In this study, we summarized the development and the in vitro and in vivo characteristics of the radiolabeled alphaMSH analogues, including 99mTc-, 111In-, 67 Ga-, or 125I labeled alphaMSH analogues for imaging with single-photon emission computed tomography; 68Ga-, 64Cu-, or 18F-labeled alphaMSH analogues for imaging with positron emission tomography; and 188Re-, 177Lu-, 90Y-, or 212Pb-labeled alphaMSH analogues for radionuclide therapy. These radiolabeled alphaMSH analogues showed promising results with high tumor uptake and rapid normal tissue activity clearance in the preclinical model of B16F1 and B16F10 mouse melanomas. These results highlight the potential of using radiolabeled alphaMSH analogues in clinical applications for molecular imaging and radionuclide therapy of melanoma. PMID- 29182037 TI - DRD4 exon 3 genotype and ADHD: Randomised pharmacodynamic investigation of treatment response to methylphenidate. AB - OBJECTIVES: Dopamine plays an important role in modulating attention and motor behaviours, dimensions altered in attention deficit/hyperactivity disorder (ADHD). Numerous association studies have linked dopamine receptor 4 (DRD4) to increased risk of ADHD. This study investigated the effect of DRD4 exon 3 polymorphism on child behaviours in response to treatment with methylphenidate. METHODS: A total of 374 children diagnosed with ADHD (ages 6-12 years) were evaluated under three experimental conditions: baseline, placebo and MPH (0.5 mg/kg/day). This was a 2-week prospective within-subject, placebo-controlled, crossover trial. The Conners' Global Index for parents and for teachers was used to evaluate the behaviours of the children. One-way repeated measures analysis of variance was used to test the effect of the interaction between DRD4 genotype and experimental conditions. RESULTS: A significant interaction between DRD4 genotype and treatment was detected when the child's behaviour was evaluated by the parents (P = 0.035, effect size of 0.014), driven by a better treatment response in children homozygous for long 7-repeat allele. CONCLUSIONS: According to the parent assessment, children homozygous for the long 7-repeat allele were more responsive to experimental condition. This is the largest pharmacogenetic investigation of the effect of DRD4 exon 3 polymorphism in childhood ADHD. TRIAL REGISTRATION: clinicaltrials.gov, identifier NCT00483106. PMID- 29182038 TI - The U.S. Health Care Crisis Continues: A Data Snapshot. AB - Despite implementation of the Affordable Care Act in 2014, the U.S. health care crisis continues. While coverage has been expanded, 28 million people remain uninsured, and tens of millions who have coverage are unable to afford care because of high cost-sharing requirements. Moreover, many with coverage have a sharply restricted choice of physicians and hospitals, and the corporate takeover of medical care in the United States is proceeding rapidly. This article provides a brief precis of recent data on U.S. health policy. PMID- 29182040 TI - Life Experience of Bereaved Parents After the 2014 Sewol Ferry Disaster in South Korea. AB - The aim of this study was to identify the outcomes of parental bereavement and the changes in life experience that follow the traumatic death of a teenage child. The results of the study are aimed to assist counselors and educators who work with themes of grief and loss. From 17 in-depth interviews from parents bereaved by the Sewol ferry disaster of 2014 in South Korea, three main categories were found to capture the reality for parents after the sudden and traumatic death of a teenage child: (a) personal changes, (b) changes in close relationships, and (c) changes in social life. Recommendations for future research and potential implications were discussed. PMID- 29182039 TI - Improvement of blood lipid profiles by Goishi tea polyphenols in a randomised, double-blind, placebo-controlled clinical study. AB - Dyslipidaemia is a risk factor for arteriosclerosis. Recent studies have shown that dyslipidaemia is effectively prevented by various polyphenols. In this clinical study (UMIN trial: 000024028), we evaluated the beneficial effects of polyphenols contained in Goishi tea on blood lipid profiles. Seventy-seven subjects with LDL cholesterol (CHO) ?120 mg/mL were randomly divided into two groups for 12 weeks of polyphenol intake as follows: the Goishi tea group for daily consumption of Goishi tea containing 122 mg of polyphenols and the placebo group for the corresponding consumption of a placebo drink containing 12.2 mg of polyphenols. Intake of Goishi tea polyphenols tended to increase HDL CHO and suppress the elevation of triglycerides. These effects were particularly notable among the subjects with a body mass index <25 kg/m2. These findings suggest that Goishi tea polyphenols may suppress arteriosclerosis and reduce cardiovascular event risk by improving blood lipid profiles and thereby preventing dyslipidaemia. PMID- 29182042 TI - Greater trochanteric pain syndrome and gluteus medius and minimus tendinosis: nonsurgical treatment. AB - Greater trochanteric pain syndrome (GTPS) affects 10-25% of people in developed countries. The underlying etiology for GTPS is most commonly the tendinosis or a tendon tear of the gluteus medius, minimus or both at the greater trochanter; the inflammation of the tendon is not a major feature. We critically evaluated conservative treatment, for which we reviewed 76 publications, grading them according to four levels of evidence. We identified a wide variety of conservative treatment options: home therapy (insoles, walking sticks/crutches, orthotic devices, stretching exercises and preventive measures); physiotherapy (massage and stretching exercises); infiltrations (corticosteroids and local anesthetics); image-guided infiltrations (fluoroscopy and ultrasound); shockwave therapy; platelet-rich plasma injection; and drug therapy. Severe complications associated with infiltrations are extremely rare, as are those associated with shockwave therapy. The most effective treatments were infiltrations with corticosteroids and shockwave therapy. We propose a graded treatment schedule for patients with GTPS. PMID- 29182041 TI - Characterization of Two Novel Deletions Involving the 5' Region of the beta Globin Gene. AB - We report two novel beta-thalassemia (beta-thal) deletions involving the 5' region of the beta-globin gene (HBB). The first deletion spans 538 bp and removes the beta-globin promoter, 5' untranslated region (5'UTR) and most of exon 1. This deletion was identified in a 3-year-old Vietnamese boy with non transfusion dependent Hb E (HBB: c.79G>A)/beta0-thal. The second deletion spans 1517 bp and removes the beta-globin gene promoter, 5'UTR, and exons 1 and 2. This deletion was identified in two unrelated adults of European descent who had beta-thal trait with unusually high Hb A2 levels. Deletions such as these are generally associated with higher levels of Hb A2 and Hb F than typical beta-thal alleles, which may ameliorate the severity of the disease. PMID- 29182043 TI - A cross-national exploration of societal-level factors associated with child physical abuse and neglect. AB - Children around the world experience violence at the hands of their caregivers at alarming rates. A recent review estimates that a minimum of 50% of children in Asia, Africa, and North America experienced severe physical violence by caregivers in the past year, with large variations between countries. Identifying modifiable country-level factors driving these geographic variations has great potential for achieving population-level reductions in rates of child maltreatment. This study builds on previous research by focusing on caregiver reported physical abuse and neglect victimisation, examining 22 societal factors representing 11 different constructs among 42 countries from 5 continents at different stages of development. Our findings suggest that gender inequity may be important for both child physical abuse and neglect. Indicators of literacy and development may also be important for child neglect. Given the limitations of the correlational findings and measurement issues, it is critical to continue to investigate societal-level factors of child maltreatment so that interventions and prevention efforts can incorporate strategies that have the greatest potential for population-level impact.

AB - BACKGROUND: Reforms are changing pension systems in many European countries, in order to both restrict early retirement and force people to extend their working life. From occupational therapy and occupational science perspectives, studies focusing on aspects of working life that motivate the older worker is urgent. AIM: The aim was to describe incentives behind an extended working life among people over age 65. METHOD: Focus group methodology was used, with participants ages 66-71, from varying work fields: construction and technical companies and the municipal elderly care sector. FINDINGS: Work was considered important and valuable to the degree of how challenging work was, the possibilities for inclusion in a team of colleagues and the chances for better personal finances. Amongst all, the participants expressed a feeling of a strengthened identity by being challenged and having the opportunity to manage working tasks. CONCLUSION: The finding showed the actual reasons behind an extended working life among older workers. However, a risk of rising social inequity may appear with increased working life if older people are forced to extend their working life due to a difficult financial situation as a pensioner. A variety of retirement options and initiatives in order to support older workers are justified. PMID- 29182045 TI - Corrigendum. PMID- 29182046 TI - Decolonizing Scoping Review Methodologies for Literature With, for, and by Indigenous Peoples and the African Diaspora: Dialoguing With the Tensions. AB - This article summarizes our deepened understanding of decolonizing research with, for, and by Indigenous peoples and peoples of African descent that emerged from conducting a scoping review of the methodological literature and reflecting on our review process. Although our review identified decolonizing methodologies as a promising approach, we questioned if our scoping review process engaged in decolonizing knowing. To unpack the epistemological tensions between decolonizing knowing and Western ways of doing scoping reviews, we engaged in individual and collective reflective processes- dialoguing with the tensions-moving from individual immersion in the literature to transformative dialogues among the team. In reflecting upon our tensions with the scoping review process, themes that emerged included (a) ontological/epistemological disjunctures, (b) tensions with concepts and language, and (c) relationships with the literature and beyond. This reflexive process provides valuable insight into ways in which review methods might be made a decolonizing research experience. PMID- 29182047 TI - The nuclear factor-kappa B pathway and response to treatment in breast cancer. AB - The nuclear factor-kappa B (NF-kappaB) pathway is known to contribute to critical signaling in cancer biology, including breast cancer, through promotion of proliferation, angiogenesis, metastasis, tumor progression, inflammation and cell survival. In this review, in vivo and in vitro studies of the NF-kappaB pathway in breast cancer are discussed, focusing on DNA damage and the epithelial mesenchymal transition associated with breast cancer stem cell properties. The relationships between NF-kappaB signaling and conventional cancer treatments in terms of response to chemo- and radiotherapy will also be discussed. Then contribution and involvement of immune system in the NF-kappaB pathway will be covered. Furthermore, the future perspective of NF-kappaB targeting as an innovative strategy to overcome refractory breast cancer, including recent updates on out-receptor activator of NF-kappaB (RANKing), will be covered. PMID- 29182048 TI - Cardiophrenic lymph node resection in advanced ovarian cancer: surgical outcomes, pre- and postoperative imaging. AB - OBJECTIVE: To evaluate the accuracy of preoperative imaging in the diagnosis of cardiophrenic lymph node (CPLN) metastases and to report perioperative outcomes after resection of CPLN at the time of cytoreductive surgery for advanced epithelial ovarian cancer (EOC). Furthermore, to assess clearance of CPLN by postoperative imaging. METHODS: All women with stage IIIC/IV EOC subjected to surgery at our institution from January 2014 to October 2016 were retrospectively identified from a database. Among these, women subjected to CPLN resection during surgery were identified. Pre- and postoperative computed tomography (CT) scans, pathology reports, surgical approach and outcomes were reviewed. RESULTS: One hundred and eighty women with stage IIIC/IV EOC subjected to surgery with curative intent were identified. Twenty-four (13%) of these women underwent CPLN resection. All had CT imaging suggestive of CPLN metastases. 20/24 (83%) had confirmed metastases upon final pathology. CPLN resection was associated with longer operation time, more often advanced upper abdominal surgery and more postoperative complications but there was no difference in days from surgery to initiation of chemotherapy. Postoperative CT was still indicative of CPLN metastases in 13/22 (59%) women despite resection with confirmative pathology. CONCLUSIONS: Resection of CPLN metastases is highly feasible without considerable added morbidity. Concern regarding surgical clearance is raised since postoperative imaging was indicative of metastases in the majority of women. The prognostic significance of stage IV disease based exclusively on CPLN metastases is unclear and any survival benefit from the procedure is yet to be determined. PMID- 29182049 TI - A qualitative study of two management models of community health centres in two Chinese megacities. AB - Two common public models of community health centres (CHCs) exist in China, i.e. the 'government-owned and government-managed' CHCs (G-CHCs) and the 'government owned and hospital-managed' CHCs (H-CHCs). Shanghai and Shenzhen are two Chinese megacities that lead the primary care development on the G-CHC and H-CHC models, respectively. Using a qualitative case study design, this study compares the management of the G-CHC model in Shanghai and H-CHC model in Shenzhen, through perspectives of a range of health providers. In each city, we randomly selected four CHCs and in total conducted 31 interviews with officers from the municipal health authorities, directors, GPs, nurses and public health doctors of the CHCs. When comparing with the H-CHC model in Shenzhen, the G-CHC model in Shanghai, a model with more simplified but accountable structure tended to present better management conditions, in terms of financial transparency, recruitment autonomy, community health workforce development (CHC staffing and family medicine training), funding and priority for public health. However, regardless of the models, staff retention remained a challenge. While our study tends to suggest that the G-CHC model in Shanghai presents better management conditions, future study can test whether and to what extent the model itself can lead to such differences.

AB - Clinical data outline the high incidence of pain syndromes in patients with multiple sclerosis, with a significant prevalence of craniofacial manifestations, including trigeminal neuralgia and migraine, which are very difficult to be managed pharmacologically. The common explanation of a localization of demyelinating plaques in areas devoted to pain modulation and integration as a trigger for pain development seems now partially unsatisfactory, since pain is often manifested well before the clinical signs of the pathology and its severity does not correlate with disease progression. This review focuses on additional mechanisms which could be at the basis of pain development in multiple sclerosis, whose identification will help identifying new targets to design more effective analgesic strategies. PMID- 29182052 TI - Estimating diagnostic accuracy for clustered ordinal diagnostic groups in the three-class case-Application to the early diagnosis of Alzheimer disease. AB - Many medical diagnostic studies involve three ordinal diagnostic populations in which the diagnostic accuracy can be summarized by the volume or partial volume under the receiver operating characteristic surface for a diagnostic marker. When the diagnostic populations are clustered, e.g. by families, we propose to model the diagnostic marker by a general linear mixed model that takes into account of the correlation on the diagnostic marker from members of the same clusters. This model then facilitates the maximum likelihood estimation and statistical inferences of the diagnostic accuracy for the diagnostic marker. This approach naturally allows the incorporation of covariates as well as missing data when some clusters do not have subjects on all diagnostic groups in the estimation of, and the subsequent inferences on the diagnostic accuracy. We further study the performance of the proposed methods in a large simulation study with clustered data. Finally, we apply the proposed methodology to the data of several biomarkers collected by the Dominantly Inherited Alzheimer Network, an international family-clustered registry to study autosomal dominant Alzheimer disease which is a rare form of Alzheimer disease caused by mutations in any of the three genes including the amyloid precursor protein, presenilin 1 and presenilin 2. We estimate the accuracy of several cerebrospinal fluid and neuroimaging biomarkers in differentiating three diagnostic and genetic populations: normal non-mutation carriers, asymptomatic mutation carriers, and symptomatic mutation carriers. PMID- 29182053 TI - Identification of potential PKC inhibitors through pharmacophore designing, 3D QSAR and molecular dynamics simulations targeting Alzheimer's disease. AB - Protein kinases are ubiquitously expressed as Serine/Threonine kinases, and play a crucial role in cellular activities. Protein kinases have evolved through stringent regulation mechanisms. Protein kinases are also involved in tauopathy, thus are important targets for developing Anti-Alzheimer's disease compounds. Structures with an indole scaffold turned out to be potent new leads. With the aim of developing new inhibitors for human protein kinase C, here we report the generation of four point 3D geometric featured pharmacophore model. In order to identify novel and potent PKCtheta inhibitors, the pharmacophore model was screened against 80,000,00 compounds from various chemical databases such as., ZINC, SPEC, ASINEX, which resulted in 127 compound hits, and were taken for molecular docking filters (HTVS, XP docking). After in-depth analysis of binding patterns, induced fit docking (flexible) was employed for six compounds along with the cocrystallized inhibitor. Molecular docking study reveals that compound 6F found to be tight binder at the active site of PKCtheta as compared to the cocrystal and has occupancy of 90 percentile. MM-GBSA also confirmed the potency of the compound 6F as better than cocrystal. Molecular dynamics results suggest that compound 6F showed good binding stability of active sites residues similar to cocrystal 7G compound. Present study corroborates the pharmacophore-based virtual screening, and finds the compound 6F as a potent Inhibitor of PKC, having therapeutic potential for Alzheimer's disease. Worldwide, 46.8 million people are believed to be living with Alzheimer's disease. When elderly population increases rapidly and neurodegenerative burden also increases in parallel, we project the findings from this study will be useful for drug developing efforts targeting Alzheimer's disease. PMID- 29182054 TI - A Quantitative Method for the Evaluation of Spatial Resolution in Quality Control of B-mode Ultrasound Images. AB - The work describes a method to quantitatively evaluate spatial resolution in B mode quality control images as radial modulation transfer function (MTF). The method is easy to use in in-field quality assurance programs in clinical institutions, as it is fast and can be performed with the help of phantoms that are already used for routine quality control. It uses a round insert with different echogenic characteristics compared with the phantom background. The method was automated with a MATLAB(r) routine, which can be run in full automatic mode or with a grade of interaction by the user, as is sometimes necessary with low-quality images. Radial MTF was evaluated for several ultrasound (US) images produced with different clinical US scanners from various vendors and equipped with different types of transducers (linear, convex, sector, vector) working at various frequencies (from 2 to 14 MHz) and with different modalities. It was also evaluated on various computed tomography (CT) images including round inserts. This was done to compare these results with the MTF calculated from the same images using the well-known method from the point spread function (PSF) of a high contrast bead. Our radial MTF method, adapted to the specific characteristics of US images, was found to be reasonably robust and in line with other methods commonly used for USs (e.g., the pin method, which has repeatability issues) and in other fields, such as X-ray CT. PMID- 29182055 TI - Amyotrophic lateral sclerosis presenting as the temporomandibular disorder: A case report and literature review. AB - BACKGROUND: Spasticity and pain in the masticatory muscles or mouth opening limitation have been reported as early signs and symptoms of amyotrophic lateral sclerosis (ALS). These signs and symptoms are also frequently seen in, and thus mistaken for, temporomandibular disorders (TMD). CLINICAL PRESENTATION: The authors report a case of ALS initially presenting with signs and symptoms of TMD. The TMD was followed by dysarthria of insidious onset, leading to the diagnosis of ALS. This case highlights the importance of considering TMD as a potential early form of presentation of ALS, requiring multidisciplinary treatment, especially by dental professionals. CONCLUSION: A review of the literature was conducted to elucidate the oral and facial signs and symptoms of ALS and to identify ways of improving the quality of life of patients through a multidisciplinary approach. PMID- 29182056 TI - Lesion Segmentation in Automated 3D Breast Ultrasound: Volumetric Analysis. AB - Mammography is the gold standard screening technique in breast cancer, but it has some limitations for women with dense breasts. In such cases, sonography is usually recommended as an additional imaging technique. A traditional sonogram produces a two-dimensional (2D) visualization of the breast and is highly operator dependent. Automated breast ultrasound (ABUS) has also been proposed to produce a full 3D scan of the breast automatically with reduced operator dependency, facilitating double reading and comparison with past exams. When using ABUS, lesion segmentation and tracking changes over time are challenging tasks, as the three-dimensional (3D) nature of the images makes the analysis difficult and tedious for radiologists. The goal of this work is to develop a semi-automatic framework for breast lesion segmentation in ABUS volumes which is based on the Watershed algorithm. The effect of different de-noising methods on segmentation is studied showing a significant impact ([Formula: see text]) on the performance using a dataset of 28 temporal pairs resulting in a total of 56 ABUS volumes. The volumetric analysis is also used to evaluate the performance of the developed framework. A mean Dice Similarity Coefficient of [Formula: see text] with a mean False Positive ratio [Formula: see text] has been obtained. The Pearson correlation coefficient between the segmented volumes and the corresponding ground truth volumes is [Formula: see text] ([Formula: see text]). Similar analysis, performed on 28 temporal (prior and current) pairs, resulted in a good correlation coefficient [Formula: see text] ([Formula: see text]) for prior and [Formula: see text] ([Formula: see text]) for current cases. The developed framework showed prospects to help radiologists to perform an assessment of ABUS lesion volumes, as well as to quantify volumetric changes during lesions diagnosis and follow-up.

PMID- 29182058 TI - Prevalence and antimicrobial susceptibility of Ureaplasma species and Mycoplasma hominis in Greek female outpatients, 2012-2016. AB - Mycoplasma hominis and Ureaplasma species are opportunistic pathogens associated with urogenital infections, complications during pregnancy and postpartum infections. Appropriate empirical antimicrobial treatment is necessary to achieve an optimal therapeutic outcome. This study evaluated the prevalence and the antimicrobial susceptibility of Mycoplasma hominis and Ureaplasma spp. isolated from 1,008 endocervical samples of outpatients in Crete, Greece, during a five year period (2012-2016), using the commercially available Mycoview kit (Zeakon diagnostics, France). Ureaplasma spp. was isolated from 116 patients (11.5%), M. hominis from 6 (0.6%), while coinfection with both mycoplasmas was demonstrated in 17 (1.7%). All Ureaplasma strains were susceptible to josamycin and doxycycline. Doxycycline, minocycline and ofloxacin were the most potent antibiotics against M. hominis. Docycycline was proved the most active and is still the drug of choice for the treatment of genital mycoplasma infections. Local surveillance to monitor changes in antimicrobial susceptibilities is necessary to guide treatment strategies. PMID- 29182062 TI - Shared decision-making in psychiatry of old age.

AB - The objective of this study was to design an enclosure suitable for studying the ecotoxicological effects of vehicle emissions on groups of wild birds without compromising welfare. Two, adjacent enclosures sheltered from sunlight, wind and rain, were bird-proofed and wrapped with thick polyethylene sheeting. Emissions were directed into the treatment enclosure from the exhaust of a light-duty gasoline truck, using flexible, heat-proof pipe, with joins sealed to prevent leakage. During active exposure, the engine was idled for 5 h/day, 6 days/week for 4 weeks. Fans maintained positive pressure (controls) and negative pressure (treatment), preventing cross-contamination of enclosures and protecting investigators. Four sets of passive, badge-type samplers were distributed across each enclosure, measuring nitrogen dioxide, sulfur dioxide and volatile organic compounds (NO2, SO2 and VOCs, respectively), and were complemented by active monitors measuring VOCs and particulate matter (2.5 um diameter, PM2.5). We found that the concentrations of NO2, SO2 and PM2.5 were not different between treatment and control enclosures. Volatile organic compounds (e.g. benzene, toluene, ethylbenzene and xylenes) were approximately six times higher in the treatment enclosure than control (13.23 and 2.13 ug m-1, respectively). In conclusion, this represents a successful, practical design for studying the effects of sub-chronic to chronic exposure to realistic mixtures of vehicle exhaust contaminants, in groups of birds. Recommended modifications for future research include a chassis dynamometer (vehicle treadmill), to better replicate driving conditions including acceleration and deceleration.

PMID- 29182077 TI - The journal of mental health would like to thank the following reviewers who have contributed to the issues in 2017. PMID- 29182076 TI - No evidence for an acute placebo effect on emotional processing in healthy volunteers. AB - Placebo-controlled trials are the gold standard measure of efficacy in the development of new treatments for depression. However, the large placebo effects associated with standard measures of subjective symptoms reduce the sensitivity of such trials to detect antidepressant effects. There is a need to develop novel efficacy markers that are resistant to placebo effects. Measures of emotional processing, known to be sensitive to antidepressant treatment, may be such a marker, although the effect of an acute placebo treatment on these measures remains unclear. We assessed the influence of placebo on a validated battery of emotional processing tasks, the Emotional Test Battery (ETB), in healthy participants. Participants were informed they might receive the antidepressant drug bupropion, placebo or no treatment, with placebo effect being estimated as the difference between the placebo and no treatment groups. We found no significant difference between these groups on measures of emotional processing. There was also no effect of subjective treatment expectancy on performance in the tasks. This suggests that the ETB might be a useful tool for Phase I trials assessing novel antidepressant agents against placebo. PMID- 29182078 TI - Foodborne botulism in Poland in 2015 AB - OBJECTIVE: The aim of this article is to assess the epidemiology of foodborne botulism in Poland in 2015compared to previous years MATERIALS AND METHODS: We reviewed (1) national surveillance data published in the annual bulletin"Infectious diseases and poisonings in Poland in 2015" and in previous publications, and (2) unpublished dataretrieved from botulism case reports for 2015 sent from Sanitary-Epidemiological Stations to the Department ofEpidemiology NIPH-NIH. RESULTS: In 2015, a total of 30 foodborne botulism cases (including 18 laboratory confirmed) was reported;the annual incidence rate (0.08 per 100,000 population) was remarkably similar to that reported in previousyear and to the median incidence for years 2009 to 2013. The highest incidence in the country was reportedin Swietokrzyskie (0.24), Lubelskie (0.23) and Zachodniopomorskie province (0.23). Incidence in rural areas(0.13 per 100,000 population) was over 3 times higher than the incidence in urban areas (0.04). Similarly, menhad more than 3 times higher incidence than women; As in previous year the highest incidence rate (0.30 per100,000 population) was observed among men in the age group of 20-24 years. Most cases were associated withconsumption of different types of commercially canned meat. Commercially produced canned fishery items werealso a common vehicle. All cases except one were hospitalized. No deaths related to the disease were reported. CONCLUSIONS: In 2015, the annual incidence of foodborne botulism in Poland was remarkably similar tothat reported in previous years. Since 2008 the number of foodborne botulism is stabilizing with an average of30 cases per year and corresponding incidence rate of 0.08 per 100,000 population. It is important to conductthorough epidemiological investigation of each case, in order to identify the most common food vehicles forbotulism and other risk factors. PMID- 29182079 TI - Undulatory Swimming Performance and Body Stiffness Modulation in a Soft Robotic Fish-Inspired Physical Model. AB - Undulatory motion of the body is the dominant mode of locomotion in fishes, and numerous studies of body kinematics and muscle activity patterns have provided insights into the mechanics of swimming. However, it has not been possible to investigate how key parameters such as the extent of bilateral muscle activation affect propulsive performance due to the inability to manipulate muscle activation in live, freely swimming fishes. In this article we extend previous work on passive flexible mechanical models of undulatory propulsion by using actively controlled pneumatic actuators attached to a flexible foil to gain insight into undulatory locomotion and mechanisms for body stiffness control. Two soft actuators were attached on each side of a flexible panel with stiffness comparable to that of a fish body. To study how bilateral contraction can be used to modify axial body stiffness during swimming, we ran a parameter sweep of actuator contraction phasing and frequency. Thrust production by the soft pneumatic actuators was tested at cyclic undulation frequencies ranging from 0.3 to 1.2 Hz in a recirculating flow tank at flow speeds up to 28 cm/s. Overall, this system generated more thrust at higher tail beat frequencies, with a plateau in thrust above 0.8 Hz. Self-propelled speed was found to be 0.8 foil lengths per second or ~13 cm/s when actuated at 0.55 Hz. This active pneumatic model is capable of producing substantial trailing edge amplitudes with a maximum excursion equivalent to 1.4 foil lengths, and of generating considerable thrust. Altering the extent of bilateral co-contraction in a range from -22% to 17% of the cycle period showed that thrust was maximized with some amount of simultaneous left-right actuation of ~3% to 6% of the cycle period. When the system is exposed to water flow, thrust was substantially reduced for conditions of greatest antagonistic overlap in left-right actuation, and also for the largest latencies introduced. This experimental platform provides a soft robotic testbed for studying aquatic propulsion with active control of undulatory kinematics. PMID- 29182080 TI - Arthrobots. AB - This article describes a class of robots-"arthrobots"-inspired, in part, by the musculoskeletal system of arthropods (spiders and insects, inter alia). Arthrobots combine mechanical compliance, lightweight and simple construction, and inexpensive yet scalable design. An exoskeleton, constructed from thin organic polymeric tubes, provides lightweight structural support. Pneumatic joints modeled after the hydrostatic joints of spiders provide actuation and inherent mechanical compliance to external forces. An inflatable elastomeric tube (a "balloon") enables active extension of a limb; an opposing elastic tendon enables passive retraction. A variety of robots constructed from these structural elements demonstrate (i) crawling with one or two limbs, (ii) walking with four or six limbs (including an insect-like triangular gait), (iii) walking with eight limbs, or (iv) floating and rowing on the surface of water. Arthrobots are simple to fabricate and are able to operate safely in contact with humans. PMID- 29182081 TI - Soft, Rotating Pneumatic Actuator. AB - This article describes a soft pneumatic actuator that generates cyclical motion. The actuator consists of several (three, four, or five) chambers (arranged around the circumference of a circle surrounding a central rod) that can be actuated independently using negative pressure (or partial vacuum). Sequential actuation of the four-chamber device using reduced pressure moves the central rod cyclically in an approximately square path. We characterize the trajectory of the actuator and the force exerted by it, as we vary the material used for fabrication, the number of chambers, and the size of the actuator. We demonstrate two applications of this actuator: to deliver fluid while stirring (by replacing the central rod with a needle) and for locomotion that mimics a reptilian gait (by combining four actuators together). PMID- 29182082 TI - Stiffness Customization and Patterning for Property Modulation of Silicone-Based Soft Pneumatic Actuators. AB - Soft pneumatic actuators (SPAs), as novel types of motion drivers for robotic devices, excel in many applications, such as rehabilitation and biomimicry, which demand compliance and softness. To further expand their scope of utilization, the SPAs should be customizable to meet the distinctive requirements of different applications. This article proposes a novel perspective on the SPA working mechanism based on stiffness distribution and then presents a versatile method called stiffness customization and patterning (SCP) for SPA body stiffness layout as a novel attempt to customize SPAs with distinctive properties. We fabricated a hybrid type of material combining unstretchable material and silicone with customizable aggregated elasticity. The tensile results showed that embedding unstretchable material directly increases the stiffness of the hybrid material sample, and our stress-strain model for SCP is able to adequately predict the elasticity of hybrid samples with specific material ratios. By applying this approach to bending-type SPAs, we are able to mitigate SPA buckling, a main failure mode of SPAs, and improve the SPA tip force by using hybrid material with globally increased stiffness. We also diversify bending modalities with different stiffness configurations in the hybrid material. SCP offers numerous ways to engineer SPAs for more applications. PMID- 29182085 TI - Learning Closed Loop Kinematic Controllers for Continuum Manipulators in Unstructured Environments. AB - This article introduces a machine-learning-based approach for closed loop kinematic control of continuum manipulators in the task space. For this purpose, we propose a unique formulation for learning the inverse kinematics of a continuum manipulator while integrating end-effector feedback. We demonstrate that this model-free approach for kinematic control is very well suited for nonlinear stochastic continuum robots. The article addresses problems that are vital for practical realization of machine-learning techniques. The primary objective is to solve the redundancy problem while making the algorithm scalable, fast, and tolerant to stochasticity, requiring minimal sensor elements and involving few open parameters for tuning. In addition, we demonstrate that the proposed controller can exhibit adaptive behavior in the presence of external forces and in an unstructured environment with the help of the morphological properties of the manipulator. Experimental validation of the proposed controller is done on a six-degree-of-freedom tendon-driven manipulator for pose control of the end effector in three-dimensional space with and without external forces. The experimental results exhibit accurate, reliable, and adaptive behavior of the proposed system, which appears suitable for the field of continuum service robots. PMID- 29182084 TI - Omni Directional Multimaterial Soft Cylindrical Actuator and Its Application as a Steerable Catheter. AB - Soft actuators with complex range of motion lead to strong interest in applying devices like biomedical catheters and steerable soft pipe inspectors. To facilitate the use of soft actuators in devices where controlled, complex, precise, and fast motion is required, a structurally controlled Omni directional soft cylindrical actuator is fabricated in a modular way using multilayer composite of polylactic acid based conductive Graphene, shape memory polymer, shape memory alloy, and polyurethane. Multiple fabrication techniques are discussed step by step that mainly include fused deposition modeling based 3D printing, dip coating, and UV curing. A mathematical control model is used to generate patterned electrical signals for the Omni directional deformations. Characterizations like structural control, bending, recovery, path, and thermal effect are carried out with and without load (10 g) to verify the new cylindrical design concept. Finally, the application of Omni directional actuator as a steerable catheter is explored by fabricating a scaled version of carotid artery through 3D printing using a semitransparent material. PMID- 29182083 TI - An Implantable Extracardiac Soft Robotic Device for the Failing Heart: Mechanical Coupling and Synchronization. AB - Soft robotic devices have significant potential for medical device applications that warrant safe synergistic interaction with humans. This article describes the optimization of an implantable soft robotic system for heart failure whereby soft actuators wrapped around the ventricles are programmed to contract and relax in synchrony with the beating heart. Elastic elements integrated into the soft actuators provide recoiling function so as to aid refilling during the diastolic phase of the cardiac cycle. Improved synchronization with the biological system is achieved by incorporating the native ventricular pressure into the control system to trigger assistance and synchronize the device with the heart. A three state electro-pneumatic valve configuration allows the actuators to contract at different rates to vary contraction patterns. An in vivo study was performed to test three hypotheses relating to mechanical coupling and temporal synchronization of the actuators and heart. First, that adhesion of the actuators to the ventricles improves cardiac output. Second, that there is a contraction relaxation ratio of the actuators which generates optimal cardiac output. Third, that the rate of actuator contraction is a factor in cardiac output. PMID- 29182086 TI - A Definition of Soft Materials for Use in the Design of Robots. PMID- 29182087 TI - Optimizing Double-Network Hydrogel for Biomedical Soft Robots. AB - Double-network hydrogel with standardized chemical parameters demonstrates a reasonable and viable alternative to silicone in soft robotic fabrication due to its biocompatibility, comparable mechanical properties, and customizability through the alterations of key variables. The most viable hydrogel sample in our article shows tensile strain of 851% and maximum tensile strength of 0.273 MPa. The elasticity and strength range of this hydrogel can be customized according to application requirements by simple alterations in the recipe. Furthermore, we incorporated Agar/PAM hydrogel into our highly constrained soft pneumatic actuator (SPA) design and eventually produced SPAs with escalated capabilities, such as larger range of motion, higher force output, and power efficiency. Incorporating SPAs made of Agar/PAM hydrogel resulted in low viscosity, thermos reversibility, and ultralow elasticity, which we believe can help to combine with the other functions of hydrogel, tailoring a better solution for fabricating biocompatible soft robots.

AB - As outcomes of patients with sickle cell anemia improve and survival into adulthood with good quality of life and expectation of long-term survival becomes more common, challenges have developed, including issues related to reproduction. Pregnancy is frequently complicated in patients with sickle cell anemia with mortality up to 4.0%. Here we report maternal perinatal mortality in two women with sickle cell anemia who died post-partum due to acute chest syndrome (ACS), caused by bone marrow fat embolism and review the literature pertinent to this subject. Patient A was a 28-year-old woman with sickle cell anemia with multiple complications. At 30 weeks' gestation she developed hemolysis associated with poor placental function necessitating delivery by C-section. The fetus was delivered successfully but she died due to multi organ failure after delivery. Autopsy showed pulmonary and amniotic fluid embolization. Patient B was a 37-year old woman with uncomplicated sickle cell anemia who presented with pre term labor and crisis, then ACS and fetal distress. The infant was delivered successfully but the patient died after cardiovascular collapse. Autopsy results showed fat and bone marrow embolization as the cause of death. Pregnancy continues to be high risk for patients with sickle cell anemia including those with mild disease. Maternal perinatal mortality could be unpredictable due to serious complications of sickle cell disease. More studies to assess maternal perinatal mortality are needed. PMID- 29182089 TI - Investigation of the arterial intima-media thickness in Behcet's disease patients without vascular complaints. AB - Objectives Behcet's disease is a multisystemic, inflammatory disease. Various factors have been implicated in the disease, including genetics, infections, immunoglobulins, immune complexes, antibodies, and oxidative stress. However, the underlying etiopathogenesis remains unclear. Behcet's disease can occur with or without vascular involvement. This prospective study investigated the relationship between the intima-media thickness of the major arteries, in addition to other factors affecting the disease process, in Behcet's disease without vascular involvement. Methods Twenty-four patients (average age: 38.50 +/ 10.931) without vascular involvement or any vascular complaints who were diagnosed with Behcet's disease were included in the study. Sixteen healthy subjects (average age: 39.75 +/- 7.793) were included as a control group. Demographic information and medical histories were recorded, and routine blood tests were performed in both groups. The intima-media thickness of the subclavian, axillary, femoral, and carotid arteries of all the participants were recorded using Doppler ultrasonography. The data were then subjected to intergroup statistical and correlation analyses. Results There were no significant differences between the arterial intima-media thickness values of the Behcet's disease patients and those of the control group ( p > 0.05). However, there was a significant difference between the neutrophil-lymphocyte ratio ( p = 0.004), low-density lipoprotein ( p = 0.007), and triglyceride ( p = 0042) levels of the two groups. Significant correlations were found between intima-media thickness and neutrophil-lymphocyte ratio levels ( p = 0.012) and the disease duration ( p = 0.030). There was also a significant correlation between the intima-media thickness of the femoral artery and disease duration ( p = 0.014). Conclusions The results showed that the duration of illness had a significant effect on arterial intima-media thickness in Behcet's disease. Blood neutrophil lymphocyte ratio levels were also associated with increased intima-media thickness. PMID- 29182090 TI - The Tactile Ethics of Soft Robotics: Designing Wisely for Human-Robot Interaction. AB - Soft robots promise an exciting design trajectory in the field of robotics and human-robot interaction (HRI), promising more adaptive, resilient movement within environments as well as a safer, more sensitive interface for the objects or agents the robot encounters. In particular, tactile HRI is a critical dimension for designers to consider, especially given the onrush of assistive and companion robots into our society. In this article, we propose to surface an important set of ethical challenges for the field of soft robotics to meet. Tactile HRI strongly suggests that soft-bodied robots balance tactile engagement against emotional manipulation, model intimacy on the bonding with a tool not with a person, and deflect users from personally and socially destructive behavior the soft bodies and surfaces could normally entice. PMID- 29182091 TI - Toward Modular Soft Robotics: Proprioceptive Curvature Sensing and Sliding-Mode Control of Soft Bidirectional Bending Modules. AB - Real-world environments are complex, unstructured, and often fragile. Soft robotics offers a solution for robots to safely interact with the environment and human coworkers, but suffers from a host of challenges in sensing and control of continuously deformable bodies. To overcome these challenges, this article considers a modular soft robotic architecture that offers proprioceptive sensing of pressure-operated bending actuation modules. We present integrated custom magnetic curvature sensors embedded in the neutral axis of bidirectional bending actuators. We describe our recent advances in the design and fabrication of these modules to improve the reliability of proprioceptive curvature feedback over our prior work. In particular, we study the effect of dimensional parameters on improving the linearity of curvature measurements. In addition, we present a sliding-mode controller formulation that drives the binary solenoid valve states directly, giving the control system the ability to hold the actuator steady without continuous pressurization and depressurization. In comparison to other methods, this control approach does not rely on pulse width modulation and hence offers superior dynamic performance (i.e., faster response rates). Our experimental results indicate that the proposed soft robotic modules offer a large range of bending angles with monotonic and more linear embedded curvature measurements, and that the direct sliding-mode control system exhibits improved bandwidth and a notable reduction in binary valve actuation operations compared to our earlier iterative sliding-mode controller. PMID- 29182092 TI - Preliminary Assessment of a Compliant Gait Exoskeleton. AB - Current commercial wearable gait exoskeletons contain joints with stiff actuators that cannot adapt to unpredictable environments. These actuators consume a significant amount of energy, and their stiffness may not be appropriate for safe human-machine interactions. Adjustable compliant actuators are being designed and implemented because of their ability to minimize large forces due to shocks, to safely interact with the user, and to store and release energy in passive elastic elements. Introduction of such compliant actuation in gait exoskeletons, however, has been limited by the larger power-to-weight and volume ratio requirement. This article presents a preliminary assessment of the first compliant exoskeleton for children. Compliant actuation systems developed by our research group were integrated into the ATLAS exoskeleton prototype. The resulting device is a compliant exoskeleton, the ATLAS-C prototype. The exoskeleton is coupled with a special standing frame to provide balance while allowing a semi-natural gait. Experiments show that when comparing the behavior of the joints under different stiffness conditions, the inherent compliance of the implemented actuators showed natural adaptability during the gait cycle and in regions of shock absorption. Torque tracking of the joint is achieved, identifying the areas of loading response. The implementation of a state machine in the control of knee motion allowed reutilization of the stored energy during deflection at the end of the support phase to partially propel the leg and achieve a more natural and free swing. PMID- 29182093 TI - Bioinspired Robotic Fingers Based on Pneumatic Actuator and 3D Printing of Smart Material. AB - In this article, we have proposed a novel robotic finger design principle aimed to address two challenges in soft pneumatic grippers-the controllability of the stiffness and the controllability of the bending position. The proposed finger design is composed of a 3D printed multimaterial substrate and a soft pneumatic actuator. The substrate has four polylactic acid (PLA) segments interlocked with three shape memory polymer (SMP) joints, inspired by bones and joints in human fingers. By controlling the thermal energy of an SMP joint, the stiffness of the joints is modulated due to the dramatic change in SMP elastic modulus around its glass transition temperature (Tg). When SMP joints are heated above Tg, they exhibit very small stiffness, allowing the finger to easily bend around the SMP joints if the attached soft actuator is actuated. When there is no force from the soft actuator, shape recovery stress in SMP contributes to the finger's shape restoration. Since each joint's rotation can be individually controlled, the position control of the finger is made possible. Experimental analysis has been conducted to show the finger's variable stiffness and the result is compared with the analytical values. It is found that the stiffness ratio can be 24.9 times for a joint at room temperature (20 degrees C) and at an elevated temperature of 60 degrees C when air pressure p of the soft actuator is turned off. Finally, a gripper composed of two fingers is fabricated for demonstration. PMID- 29182094 TI - Origami Wheel Transformer: A Variable-Diameter Wheel Drive Robot Using an Origami Structure. AB - A wheel drive mechanism is simple, stable, and efficient, but its mobility in unstructured terrain is seriously limited. Using a deformable wheel is one of the ways to increase the mobility of a wheel drive robot. By changing the radius of its wheels, the robot becomes able to pass over not only high steps but also narrow gaps. In this article, we propose a novel design for a variable-diameter wheel using an origami-based soft robotics design approach. By simply folding a patterned sheet into a wheel shape, a variable-diameter wheel was built without requiring lots of mechanical parts and a complex assembly process. The wheel's diameter can change from 30 to 68 mm, and it is light in weight at about 9.7 g. Although composed of soft materials (fabrics and films), the wheel can bear more than 400 times its weight. The robot was able to change the wheel's radius in response to terrain conditions, allowing it to pass over a 50-mm gap when the wheel is shrunk and a 50-mm step when the wheel is enlarged. PMID- 29182095 TI - Fin Ray Stiffness and Fin Morphology Control Ribbon-Fin-Based Propulsion. AB - Ribbon-fin-based propulsion has rich locomotor capabilities that can enhance the mobility and performance of underwater vehicles navigating in complex environments. Bony fishes using this type of propulsion send one or multiple traveling waves along an elongated fin with the actuation of highly flexible rays that are interconnected by an elastic membrane. In this work, we study how the use of flexible rays and different morphology can affect the performance of ribbon-fin propulsion. We developed a physical model composed of 15 rays that are interconnected with an elastic membrane. We tested four different ray flexural stiffness and four aspect ratios. The robotic model was tested in a low turbulence flume under two flow conditions ([Formula: see text] wavelength/s). In two experimental sets, we measured fin kinematics, net surge forces, and power consumption. Using these data, we perform a thrust and power analysis of the undulating fin. We present the thrust coefficient, power coefficient, and propulsive efficiency. We find that the thrust generation was linear with the enclosed area swept by the fin, and square of the relative velocity between the incoming flow and traveling wave. The thrust coefficient levels off around 0.5. In addition, for our parameter range, we find that the power consumption scales by the cube of the effective tangential velocity of the rays [Formula: see text] (A is the amplitude of the ray oscillating motion, and [Formula: see text] is the angular velocity). We show that a decay in stiffness decreases both thrust production and power consumption. However, for rays with high flexural stiffness, the difference in thrust compared with rigid rays is minimal. Moreover, our results show that flexible rays can improve the propulsive efficiency compared with a rigid counterpart. Finally, we find that the morphology of ribbon fin affects its propulsive efficiency. For the aspect ratio considered in our experiments, [Formula: see text] was the most efficient compared with [Formula: see text]. Our results suggest that there could be an optimal morphology for a given ribbon fin kinematics. Therefore, both natural swimmers and underwater vehicles using ribbon-fin-based propulsion can take advantage of flexible rays and optimal aspect ratio to improve propulsive performance. PMID- 29182096 TI - Leveraging Internal Viscous Flow to Extend the Capabilities of Beam-Shaped Soft Robotic Actuators. AB - Elastic deformation of beam-shaped structures due to embedded fluidic networks (EFNs) is mainly studied in the context of soft actuators and soft robotic applications. Currently, the effects of viscosity are not examined in such configurations. In this work, we introduce an internal viscous flow and present the extended range of actuation modes enabled by viscosity. We analyze the interaction between elastic deflection of a slender beam and viscous flow in a long serpentine channel embedded within the beam. The embedded network is positioned asymmetrically with regard to the neutral plane and thus pressure within the channel creates a local moment deforming the beam. Under assumptions of creeping flow and small deflections, we obtain a fourth-order integro differential equation governing the time-dependent deflection field. This relation enables the design of complex time-varying deformation patterns of beams with EFNs. Leveraging viscosity allows to extend the capabilities of beam-shaped actuators such as creation of inertia-like standing and moving wave solutions in configurations with negligible inertia and limiting deformation to a small section of the actuator. The results are illustrated experimentally. PMID- 29182097 TI - A Practical Approach to Soft Actuation. PMID- 29182098 TI - The JamHand: Dexterous Manipulation with Minimal Actuation. AB - From using chopsticks to grab items off a plate, to snapping together two LEGO bricks in one hand, common manipulation tasks are easy for humans. However, grasping and dexterous manipulation still rank among the principal grand challenges in robotics. A key challenge is the complex interaction between hand biomechanics and motor control, leading to humanoid hands that remain too complex and costly for use in daily tasks. Here, we bypass this challenge by offering an alternative approach based on multi-finger material phase transition effects. By limiting our focus to dexterous manipulation, we are able to design a robotic hand that can achieve six fundamental dexterous manipulations as well as precision and power grasps, all with only two actuators. We further demonstrate our system on a range of real-world grasping and manipulation challenges. Besides practical application, these results suggest that leveraging the phase transition of granular materials is a viable technique for reducing the hand complexity required for performing daily tasks. PMID- 29182099 TI - An Overview of Shape Memory Alloy-Coupled Actuators and Robots. AB - The one-dimensional deformation of shape memory alloy (SMA) wires and springs can be implemented into different types of functional structures with three dimensional deformations. These structures can be classified based on the type of structure and how the SMA element has been implemented into the following categories: rigid mechanical joints, semi-rigid flexural hinges, SMA elements externally attached to a soft structure, and embedded into the soft structure. These structures have a wide range of properties and implementation requirements, and they have been used to produce a variety of robots with rigid and soft motions. The different research efforts to develop actuators and robots related to each type of structure are presented along with their respective strengths and weaknesses. A model is then developed to discuss the performance and applicability of SMA wires versus SMA springs for actuators with a polymeric matrix to see the effect of each type of SMA on the selection of design parameters. A comparison of the different types of structures and the applicability of different types of SMA elements for different types of structures is then presented. PMID- 29182100 TI - Dielectric Elastomer Actuators for Soft Wave-Handling Systems. AB - This article presents a soft handling system inspired by the principle of the natural wave (named Wave-Handling system) aiming to offer a soft solution to delicately transport and sort fragile items such as fruits, vegetables, biological tissues in food, and biological industries. The system consists of an array of hydrostatically coupled dielectric elastomer actuators (HCDEAs). Due to the electrostriction property of dielectric elastomers, the handling system can be controlled by electric voltage rather than the cumbersome pneumatic system. To study the working performance of the Wave-Handling system and how the performance can be improved, the basic properties of HCDEA are investigated through experiments. We find that the HCDEA exhibits some delay and hysteretic characteristics when activated by periodic voltage and the characteristics are influenced by the frequency and external force also. All this will affect the performance of the Wave-Handling system. However, the electric control, simple structure, light weight, and low cost of the soft handling system show great potential to move from laboratory to practical application. As a proof of design concept, a simply made prototype of the handling system is controlled to generate a parallel moving wave to manipulate a ball. Based on the experimental results, the improvements and future work are discussed and we believe this work will provide inspiration for soft robotic engineering. PMID- 29182101 TI - Design and Fabrication of Soft Morphing Ray Propulsor: Undulator and Oscillator. AB - A soft morphing ray propulsor capable of generating an undulating motion in its pectoral fins was designed and fabricated. The propulsor used shape memory alloy for actuation, and the body was made with soft polymers. To determine the effects of undulation in the fins, two models that differed in terms of the presence of undulation were fabricated using different polymer materials. The experimental models were tested with a dynamometer to measure and compare thrust tendencies. Thrust measurements were conducted with various fin beat frequencies. Using the experimental data, the concept of an optimized standalone version of the ray robot was suggested and its prototype was fabricated. The fabricated robot was able to swim as fast as 0.26 body length per second and 38% more efficient than other smart material-based ray-like underwater robots. PMID- 29182102 TI - A Novel Concept for Safe, Stiffness-Controllable Robot Links. AB - The recent decade has seen an astounding increase of interest and advancement in a new field of robotics, aimed at creating structures specifically for the safe interaction with humans. Softness, flexibility, and variable stiffness in robotics have been recognized as highly desirable characteristics for many applications. A number of solutions were proposed ranging from entirely soft robots (such as those composed mainly from soft materials such as silicone), via flexible continuum and snake-like robots, to rigid-link robots enhanced by joints that exhibit an elastic behavior either implemented in hardware or achieved purely by means of intelligent control. Although these are very good solutions paving the path to safe human-robot interaction, we propose here a new approach that focuses on creating stiffness controllability for the linkages between the robot joints. This article proposes a replacement for the traditionally rigid robot link-the new link is equipped with an additional capability of stiffness controllability. With this added feature, a robot can accurately carry out manipulation tasks (high stiffness), but can virtually instantaneously reduce its stiffness when a human is nearby or in contact with the robot. The key point of the invention described here is a robot link made of an airtight chamber formed by a soft and flexible, but high-strain resistant combination of a plastic mesh and silicone wall. Inflated with air to a high pressure, the mesh silicone chamber behaves like a rigid link; reducing the air pressure, softens the link and rendering the robot structure safe. This article investigates a number of link prototypes and shows the feasibility of the new concept. Stiffness tests have been performed, showing that a significant level of stiffness can be achieved-up to 40 N reaction force along the axial direction, for a 25-mm diameter sample at 60 kPa, at an axial deformation of 5 mm. The results confirm that this novel concept to linkages for robot manipulators exhibits the beam-like behavior of traditional rigid links when fully pressurized and significantly reduced stiffness at low pressure. The proposed concept has the potential to easily create safe robots, augmenting traditional robot designs. PMID- 29182103 TI - Association of mitochondrial copy number variation and T16189C polymorphism with colorectal cancer in North Indian population. AB - Globally, colorectal cancer is the third most common type of cancer. Genetic instability leading to cancer development is one of the major causes for development of cancer. Alterations in mitochondrial genome, that is, mutations, single-nucleotide polymorphisms, and copy number variations are known to contribute in cancer development. The aim of our study was to investigate association of mitochondrial T16189C polymorphism and copy number variation with colorectal cancer in North Indian population. DNA isolated from peripheral blood of 126 colorectal cancer patients and 114 healthy North Indian subjects was analyzed for T16189C polymorphism and half of them for mitochondrial copy number variation. Genotyping was done using polymerase chain reaction-restriction fragment length polymorphism, and copy number variation was estimated using real time polymerase chain reaction, numbers of mitochondrial copies and found to be significantly higher in colorectal cancer patients than healthy controls (88 (58 154), p = 0.001). In the regression analysis, increased mitochondrial copy number variation was associated with risk of colorectal cancer (odds ratio = 2.885, 95% confidence interval = 1.3-6.358). However, T16189C polymorphism was found to be significantly associated with the risk of rectal cancer (odds ratio = 5.213, p = 0.001) and non-significantly with colon cancer (odds ratio = 0.867, p = 0.791). Also, false-positive report probability analysis was done to validate the significant findings. Our results here indicate that mitochondrial copy number variation may be playing an important role in the development of colorectal cancer, and detection of mitochondrial copy number variation can be used as a biomarker for predicting the risk of colorectal cancer in North Indian subjects. PMID- 29182104 TI - Steered molecular dynamics for studying ligand unbinding of ecdysone receptor. AB - Ecdysone receptor (EcR) is an important target for pesticide design. Ligand binding regulates EcR transcriptional activity similar to other nuclear receptors; however, the pathways by which ligands enter and leave the EcR remain poorly understood. Here, we performed computational studies to identify unbinding pathways of an ecdysone agonist [the selective ecdysone agonist, BYI06830] from the EcR ligand binding domain (EcR LBD). BYI06830 can dissociate from EcR LBD via four different pathways with little effect on receptor structure. By comparing the potential of mean force (PMF) of four pathways, path 2 was considered to be the most likely exit path for BYI06830, which was located in the cleft formed by the H3-H4 loop, H6-H7 loop, and the H11 C-terminus. Furthermore, structural features along path 2 were analyzed and the structural snapshots of the metastable and transition states were isolated to illustrate the unbinding mechanism of ecdysone agonist from EcR LBD. PMID- 29182105 TI - A meta-analysis of external fixation and flexible intramedullary nails for femoral fractures in children. AB - Background : The purpose of this meta-analysis was to compare the outcomes of external fixation and flexible intramedullary nails for femoral fractures in children between 5 and 15 years of age based on the current evidence. Materials and methods: We searched relevent studies in the following database: Cochrane library, PubMed and EMABASE up to May 2014. All randomized controlled trials, Clinical controlled trials and retrospective controlled studies comparing external fixation and flexible intramedullary nails in femoral fractures of children were included. Data was extracted independently for meta-analysis. Results: Seven trials altogether involving 338 cases of femoral fractures of children treated by external fixation (128 cases) and flexible intramedullary nails (210 cases) were included in the meta-analysis. Results showed that flexible intramedullary nails was superior to external fixation in less time to union , lower postoperative infection rate and refracture rate . It may not increase delayed union, Limb-length discrepancy , pain and bursitis . Both fixations obtained a similar patient satisfaction. conclusion: Flexible intramedullary nail had greater advantages for the treatment of femoral fractures in children aged 5-15 years, compared to external fixation based on current meta analysis. This conclusion will ultimately require rigorous and adequately powered randomized controlled trials to be proved. PMID- 29182106 TI - Multidisciplinary approach to osteosarcoma. AB - Osteosarcoma is a malignant bone tumor composed of mesenchymal cells producing osteoid and immature bone. Osteosarcoma is the most frequent primary malignant bone tumor, if we excluded myeloma, a haematologic disease. The incidence of osteosarcoma is 2-3/million/year, but is higher in adolescence, in which the annual incidence peaks at 8-11/million/year at 15-19 years of age. Local pain, followed by localized swelling and limitation of joint movement, are the typical signs and symptoms. Correct diagnosis can be achieved through a correct approach to the disease and the combination of clinical and radiographic aspects. The final step to confirm the diagnosis is the biopsy. Computer Tomography of the chest and Positron-Emission Tomography are mandatory to complete the staging, which is performed according the Musculoskeletal Tumor Society staging system. A multidisciplinary approach is needed both to get to a correct diagnosis (orthopaedic surgeon, radiologist and histopathologist) and to perform definitive treatment. Multidisciplinary approach should be performed in reference centers able to provide access to the full spectrum of care and where orthopaedic surgeon, oncologist, histopathologist, radiologist and radiotherapist can cooperate. The management of osteosarcoma is based primarily on neo-adjuvant and adjuvant chemotherapy and surgical resection; radiotherapy is not effective as osteosarcomas are relatively radioresistant. Prognostic factors include metastases at presentation, histologic response to induction chemotherapy, the site of the primary tumor (with axial lesions having an inferior outcome), serum lactate dehydrogenase and alkaline phosphatase levels. PMID- 29182107 TI - Displaced distal end radius fractures in children treated with Kirschner wires - A systematic review. AB - The indications for Kirschner wiring, the technique of wiring, type of cast immobilization, period of immobilization and complications of K wires are unclear. We conducted a systematic review of the literature on Kirschner wiring of distal radius fractures in children. A total of 4263 articles were identified. The full text of the remaining 78 articles was reviewed. 64 articles were finally excluded because of incomplete data leaving 14 for analysis. Complete fracture displacement and translation more than 50% are the commonest indications for Kirschner wiring of these fractures with 2 retrograde wires in non-Kapandji fashion being the commonest technique. Long arm casts are the favored modality of immobilization with superficial infection being the commonest complication. Re displacement rates are low after Kirschner wiring. Most studies were retrospective and there is the need for a multicenter randomized controlled trial to define protocols for management of displaced distal radius fractures in children. PMID- 29182108 TI - Triple pelvic osteotomy for the treatment of symptomatic acetabular dysplasia in adolescents and adults : A review of 42 hips. AB - We treated 42 hips with symptomatic acetabular dysplasia using triple pelvic osteotomy. The mean age of the patients was 20.7 years (12-47). The median follow up was 50.3 months. The average Harris hip score improved from 74 to 92 points. Significant improvement from the preoperative to the latest follow-up evaluation was seen radiologically with reference to the center-edge angle, the anterior center-edge angle, the acetabular index and the femoral head extrusion index. Shenton's line was intact in 9 hips before the operation and it was intact in 40 hips at the latest follow-up. The cross-over sign was present in 15 hips before the operation and it was present in one hip after the operation. The results of this study demonstrated that triple pelvic osteotomy provides improved radiographic results and good symptomatic relief in acetabular dysplasia. PMID- 29182109 TI - Factors affecting outcome after the use of the Ponseti method for the management of idiopathic clubfoot, a retrospective study in an orthopaedic referral institute. AB - TIn the last few decades Ponseti method has replaced soft tissue releases as the gold standard in the management of idiopathic clubfoot. However, the recurrence of the deformity is common without post tenotomy bracing. The purpose of this study was to retrospectively see various attributes of the patients associated with poor outcome after use of Ponseti method in idiopathic clubfoot management. Seventy nine consecutive patients with one hundred and twenty three idiopathic clubfeet treated with Ponseti method by single orthopaedic surgeon were followed for a period of two years and recurrence of the deformity was studied in relation to age of patient at presentation (< 3 months or more), sex of the patient, severity of the deformity ( moderate to severe verses (Vs.) very severe), compliance to post tenotomy bracing (compliant Vs. non compliant), educational level of parents (high school or less) and access of parents to internet (Yes or No) and odds ratio for recurrence and level of significance determined for each using Fisher's exact t-test. Non compliance in seventeen patients (17.7%) with post tenotomy bracing was the most important factor related to the recurrence, with an odds ratio of 6.22 (P =0.0059). Educational level (less than high school) of parents (36.7%) was the second most important factor with odds ratio of 5.5 (P=0.0073). Fifteen patients with severe Demiglio scoring feet had an odds ratio of 5.3 (P= 0.0097) for the recurrence of the deformity. Inaccess of the parents to the internet had an odds ratio of 6.33 (P =0.011) for the recurrence of the deformity. Age and sex of the patients was not found to have a significant effect on the recurrence of the deformity. In conclusion, the risk factors associated with recurrence of the idiopathic clubfoot deformity except severity of the deformity are modifiable and extra minutes can be spent with risk group parents during follow up visits to prevent a recurrence by making them understand natural history of the corrected foot without post tenotomy bracing, encouraging them for regular follow up visits, arranging interactive sessions with other patients who are regular in their follow up and compliant with bracing, and encouraging the literate parents to update their information about clubfoot from internet. PMID- 29182110 TI - Difference between Spinecor brace and Thoracolumbosacral orthosis for deformity correction and quality of life in adolescent idiopathic scoliosis. AB - Although there are several conservative treatment options, only bracing has been found to be effective in preventing curve progression and a subsequent need for surgery in adolescent idiopathic scoliosis. The objective of this study is to compare the results of SpineCor brace and thoracolumbosacral orthosis (TLSO) for treatment of adolescent idiopathic scoliosis radiologically and clinically. Sixty four patients with adolescent idiopathic scoliosis treated with brace included in this study. Height, T1-Coccygx distance, and gibbosity were measured. Rib hump deformity was evaluated with a scoliometer. An SRS-22 questionnaire was used to determine the quality of life of patients after the first year of brace treatment. Differences in Cobb angles and gibbosity were insignificant for both groups. SRS-22 questionnaire results showed significant differences in pain, self image and function/activity subgroups. Patients' mental health and satisfaction scores were insignificant. These braces have a similar effect on deformity correction. The surgery rates and success rates of braces are approximately equal. The major difference between SpineCor and TLSO is health-related quality of life. PMID- 29182111 TI - The effect of distraction-based growth-friendly spinal instrumentation on growth in early-onset scoliosis. AB - The present study assessed the advantages and disadvantages of growth-friendly spinal instrumentation surgery for early-onset scoliosis in 17 patients who underwent this surgery with a minimum 2-year follow-up. The mean number of lengthening procedures was three, initial age at which surgery was performed was 108.1 +/- 30.2 months, and follow-up duration was 40.6 +/- 16.6 months. Spinal height (T1-S1 and T1-T12), lung space available, major Cobb angle for scoliosis, maximum thoracic kyphosis, lumbar lordosis, shoulder and pelvic balance, and coronal and sagittal balance were assessed preoperatively and at the last follow up. Treatment with growth-friendly spinal instrumentation showed evident increases in the spinal height and space available for the lungs, and significant improvement in scoliosis and thoracic kyphosis. The most commonly observed complications were proximal anchor problems and proximal junctional kyphosis. To avoid proximal junctional kyphosis in treatments with growing rods, excessive thoracic kyphosis correction should not be performed. PMID- 29182112 TI - Treatment outcome in 60 children with pathological fractures of the humerus caused by juvenile or aneurysmal bone cysts. AB - The treatment of pathological fractures of the humerus caused by juvenile or aneurysmal bone cysts (JBC/ABC) should be a single approach with a high success rate and low complication rate. This study evaluates how day by day treatment concepts fulfil these aims. Children below 15 years of age with a pathological fracture of the humerus caused by a JBC or ABC between 01.01.2001 and 31.12.2010, were investigated by chart review in four major paediatric trauma centres. Age, gender, fracture localisation, X-ray findings, treatment and outcome - assessed by the Capanna classification (I to IV), were analysed. 60 children [41male, 19 female; mean age: 9 years (4-14 years)] with 43 JBC and 12 ABC were included as well as five cysts, who could not be classified definitively. First treatment was non-operatively in 33 children. Of these 27 cysts did not improve; likewise the supportive installation of cortisone in six patients did not change the outcome. The first treatment consisted of elastic stable intramedullary in 13 children; up to three nail exchanges included. But only six of these reached (nearly) complete resolution (I/II). Overall the combined mechanical and biological treatment with curettage, elastic stable intramedullary nailing, (artificial) bone substitute and in some cases growth factors was performed as the 1st-line treatment in nine patients and further in 2nd or 3rd-line treatments in 13 humeral cysts. More than half of these reached a complete or nearly complete resolution of the cyst (12x I, 5x II, 1x III, 4x IV). Major complications in all operated patients were six nails not removable and two children with upper extremities length differences. Healing rates are low for non-operative treatment, elastic stable intramedullary nailing alone and by using cortisone for cysts resolution in pathological fractures of the humerus. Data support a combined mechanical and biological treatment with curettage, elastic stable intramedullary nailing, (artificial) bone substitute and the use of growth factors.

Pre/post-operative clinical and radiological assessments were analyzed. A transient L5 nerve root paralysis was observed in one patient with L5 spondylolisthesis. No degenerative spondylolisthesis or adjacent segmental instability occurred above the fusion segments. In conclusion, we suggest that, in case of spondylolisthesis without severe structural scoliosis deformity or only associated with lumbosacral deformity, the posterior ligament complex should be protected in case of adjacent segmental instability and spondylolisthesis. If the spondylolisthesis is complicated with severe structural scoliosis deformity (Cobb >= 70 degrees ), in principle, the treatment should be performed according to the characteristics of the two diseases respectively. PMID- 29182114 TI - Assessment of the Medial Longitudinal Arch in children with Flexible Pes Planus by Plantar Pressure Mapping. AB - INTRODUCTION: Plantar Pressure mapping was introduced as a new modality for assessment of the height of the medial longitudinal arch of the foot. Therefore, the aim of this study is to correlate the plantar pressure mapping readings of arch index contact force ratio (AICFR) in children with flexible pes planus with radiographic measurements and static plantar footprints in order to determine the reliability of pressure mapping as a modality for the assessment and follow up of the flat foot deformity. PATIENTS AND METHODS: Radiographic measurements, foot prints, and pressure mapping scans were recorded for each foot at initial presentation and at latest follow up in 28 children (56 feet) with flexible pes planus. RESULTS: A positive correlation of pressure mapping results was found with the talo-first metatarsal angle, the calcaneal pitch angle, as well as the footprint scans (P < 0.001). CONCLUSION: This study demonstrated that plantar pressure mapping is a reliable and effective tool in screening, diagnosis, and follow up of children with flexible pes planus. PMID- 29182115 TI - Management of adolescent tibia vara using Taylor spatial frame. AB - PURPOSE: Adolescent tibia vara is a multiplanar deformity that can lead to progressive deformity, altered gait, unequal leg lengths, and premature knee arthritis if uncorrected. The purpose of the current study is to report our experience in management of adolescent tibia vara using Taylor Spatial Frame (TSF). MATERIALS AND METHODS: A prospective study of eleven adolescent tibia vara patients managed by proximal tibial osteotomy gradual deformity correction using TSF. RESULTS: The average time in the frame was 123.5 (+/-25.5) days. At final follow up (average 15 (+/-2) months), the mean post-operative mPTA was 87 (+/-4) degrees (range 81 to 93 degrees), where the mean preoperative mean mPTA was 68 (+/-9) degrees (range 49 to 77 degrees) (p value 0.003). The mean postoperative MAD was 12.2(+/-11.4) mm, range (-1 to 26 mm), where preoperative mean MAD was 75.7(+/-14.7 mm), range (60 to 107mm) (p value 0.003). The mean postoperative PPTA was 80(+/-2) degrees, range (77 to 83 degrees), while the preoperative mean PPTA was 72 (+/-12) degrees, range (42 to 82 degrees) (p value 0.028). CONCLUSION: Although we have not directly compared the TSF with the Ilizarov fixator, this series serves to highlight the versatility and effectiveness of the TSF in the treatment of complex and often obstinate adolescent tibia vara. PMID- 29182116 TI - Surgical treatment for developmental dysplasia of the hip- a single surgeon series of 47 hips with a 7 year mean follow up). AB - The treatment of developmental dysplasia of the hip (DDH) in children remains controversial. We describe the clinical and radiological outcomes of 47 hips in 43 children treated with open surgery by one surgeon between 2004 and 2008 for DDH. The mean age at operation was 25 months (5 to 113) with a mean follow up of 89 months (22 to 169). At the latest follow up 40 of the 45 hips where Severin grades were recordable (89%) were graded as excellent or good, Severin class I or II. Clinically significant AVN (grade II to III according to the Kalamchi and MacEwen classification) was seen in 6 (13%) of the hips. We found a pelvic osteotomy to be a risk factor for AVN (p 0.02) and age at operation to be a risk factor for poor morphology at final follow up (p 0.03). Over 18 months old a pelvic osteotomy should be performed in selective cases depending on intra operative stability, but we will now consider doing this as a staged procedure and delaying the osteotomy for a period of time after open reduction to reduce the risk of AVN. PMID- 29182117 TI - Osteochondral fractures of the knee in skeletally immature patients: short term results of operative fixation using Omnitech screws. AB - PURPOSE: Osteochondral fractures in skeletally immature patients are rare. A retrospective case series is reported looking at the use of Omnitech compression screws for these injuries. METHOD: Nine patients with a mean age of 14 were included in the study with a mean follow up of 26 months. RESULTS: The average KOOS, IKDC and Tegner Lysholm Scores were 86.7, 90.34 and 96.1 respectively. CONCLUSION: The use of Omnitech screws in the acute setting for skeletally immature patients shows excellent short-term outcomes. PMID- 29182118 TI - Aneurysmal bone cystic lesions: value of genomic studies. AB - Aneurysmal bone cystic (ABC) lesions can be primary or secondary (to a trauma or a pre-existing benign or malignant tumour). Specific translocations of the USP6 gene are reported in about 70% of primary but never in secondary ABC lesions. We report two cases of ABC lesions in which imbalanced genomic aberrations were detected at initial presentation and showed complex clonal evolution. These demonstrative observations strengthen the guidelines regarding the diagnostic approach when an ABC is suggested by imaging. Biopsy is mandatory including genomic analysis. When a primary ABC is not clearly proven by the initial biopsy, an extensive curettage should be performed, with pathological examination of all removed tissue in order to exclude a secondary ABC. It also illustrates the added value of genomic analyses in the setting of an ABC lesion: complex clonal aberrations argues for a lesion secondary to a malignant proliferation whereas USP6 rearrangement allows the diagnosis of primary ABC. PMID- 29182119 TI - IA comparison of two minimally invasive procedures for intra-articular displaced calcaneal fractures in older children. AB - The purpose of this study was to compare the clinical outcomes of displaced intra articular calcaneal fractures in older children treated with poking reduction and cannulated screws fixation or with plate fixation using a sinus tarsi approach. From June 2008 to May 2012, fifty patients were randomised to operative stabilisation either by poking reduction and cannulated screws fixation (Group A, 28) or by plates fixation using a sinus tarsi approach (Group B, 22). The two groups were comparable with respect to age, gender, BMI, the affected side, cause of injury, fracture type, time from injury to surgery and follow-up time. We collected data on operative time and radiation time, length of hospitalization, hospital costs, union time, full weight-bearing time, full physical activity time and complications and measured joint function using the American Orthopaedic Foot and Ankle surgery (AOFAS) score. The average follow-up time of Group A was 36.5+/ 9.3 months and 40.2+/-10.6 months in Group B. No significant difference between these two groups was found in radiation time, average length of hospitalization, union time, full weight-bearing time, full physical activity time and the average AOFAS score. However, the patients of Group B had longer operation time (38.0+/ 10.6 min vs. 66.5+/-9.4 min, P<0.05) and more hospital costs (6200+/-800 RMB vs. 15000+/-2000 RMB, P<0.05). The average Bohler's angle and Gissane's angle preoperative were 10.9+/-5.3 and 141.3+/-12.1 in Group A, and became 31.2+/-5.1 and 128.5+/-5.4 after operation. The average Bohler's angle and Gissane's angle preoperative in Group B were 11.7+/-4.0 and 138.8+/-16.2, respectively, and they became 30.9+/-5.2 and 124.6+/-6.8 after operation. Bohler's angle and Gissane's angle were significantly restored after surgery (P<0.05). Postoperative incision pain was more frequent in Group B than in Group A (P<0.05). Our results indicated that both cannulated screws and plates were efficient methods for intra-articular calcaneal fractures in older children. However, poking reduction and cannulated screws fixation had the advantages of a shorter operative time, fewer hospital costs and less incision pain. PMID- 29182121 TI - Primary epiphyseal and metaepiphyseal tubercular osteomyelitis in children A series of 8 case. AB - : Clinical series of primary epiphyseal and metaepiphyseal tubercular osteomyelitis are few. The purpose of our study was to retrospectively review the presentation, healing response and functional results of 8 such cases in children. MATERIAL AND METHODS: The patients were evaluated for pain, deformity, range of motion, limb length discrepancy (if any) and recurrence. Serial radiographs of the region were studied to see remineralization, obliteration of radiological lesions, status of physis and remodeling of the growth plate. RESULTS: The mean patient age was 7.1 years. Average follow up was 3.7 years. The mean duration of symptom before presentation was 2.9 months (range, 0.5-8 months). Knee region was involved in 4, distal radius in 2, shoulder and distal fibula in 1 patient each. The lesions were either localized or diffuse depending upon physeal involvement and osseous destruction. At the last follow up, the involved joints were painfree and had useful range of motion. Limb length lengthening was seen in all knee patients. The diffuse variety resulted in premature physeal closure. The residual lucencies persisted for several years without any clinical manifestations. CONCLUSIONS: Primary epiphyseal and metaepiphyseal tuberculosis was relatively uncommon. The clinical outcome was good following curettage and multidrug antitubercular therapy. The epiphyseal and metaphyseal lucencies persisted for several months even after successful treatment. The diffuse variety lead to premature physeal closure. Limb length lengthening was common sequelae of tuberculosis of knee region. PMID- 29182120 TI - Risk factors for additional surgery after closed reduction of hip developmental dislocation. AB - PURPOSE: to evaluate the risk factors for additional surgery after closed reduction of hip developmental dislocation Methods : closed reduction for developmental hip dislocation was performed on 72 patients, with a total of 82 hips (10 bilateral). Were included only patients with irreducible hip dislocation who were treated by overhead traction followed by closed reduction under general anaesthesia and spica casting. The mean age at the time of closed reduction was 10 months, with 82% of dislocation diagnosed after the age of 6 months. In 28 hips (34.1%), no additional surgical procedure was necessary, while 54 hips (65.9%) needed an additional surgery, consisting in Salter osteotomy in 40 hips (48.8%) or open hip reduction in 14 (17.1%). RESULTS: risk factors for the need of additional surgery were: older age at the time of reduction, male sex, high grade of hip dislocation (Tonnis grade 3 and 4, versus grade 1 and 2), and quality of hip reduction. All the patients older than 17 months at the time of closed reduction needed additional surgery. Bilateral hip dislocation had poorer Severin grading than unilateral dislocation. Poorer Kalamchi scoring was associated with older age and with the presence of the cephalic nucleus at the time of reduction. CONCLUSION: this study confirmed delayed diagnosis of hip dislocation leads to a more extensive treatment with poorer issue. PMID- 29182122 TI - Complications associated with bone lengthening of the lower limb by callotasis. AB - The present study aims to assess the incidence of complications related to bone lengthening procedures and to identify factors that may predict these complications. We retrospectively studied 51 lengthening procedures in 39 patients (mean age 13 years) from 2001 to 2015. A circular external fixator was used in 37 procedures and a monolateral fixator in 14 procedures. Duration of distraction, fixator's time, days of treatment, lengthening percentage, bone healing index, distraction regenerate length, distraction index, risk factors and complications were evaluated. The mean follow-up was 5 years. Complications occurred in 84 % of the procedures. Duration of distraction, fixator's time, days of treatment and distraction regenerate length were predictors of complications. Close follow-up is necessary during distraction and healing period and after fixator removal. PMID- 29182123 TI - Angular deformity development after the distal tibial physeal fractures. AB - : Several clinical and radiological factors can be prognostic in the development of angular deformity following physeal injuries of the distal tibia. One of the radiological parameters, premature physeal closure (PPC), can be detected during postoperative follow-ups. Aim of our study was to identify the prognostic factors in development of angular deformity and its relationship with PPC. One hundred and four patients treated due to physeal injuries of the distal tibia were included in our study. Patients were divided into three groups based on Salter Harris (SH) classification. The intergroup relationships between sex, age, the amount of energy sustained during injury, premature physeal closure, the amount of residual gap, and deformity were analyzed. Angular deformity developed in 25% (3/12) of SH Type 2, in 60% (9/15) of Type 3 and 30% (3/10) of Type 4 patients with PPC. A residual displacement of more than 2 mm, age and premature physeal closure were specified as significant risk factors for development of angular deformity. 2 mm limit for residual displacement and findings of premature physeal closure in the radiological evaluations during follow-ups are prognostic factors in avoiding malalignment of the distal tibia. LEVEL OF EVIDENCE: Level 3. PMID- 29182124 TI - Hip preservation surgery for adolescents and young adults with Post-Perthes Sequelae. AB - BACKGROUND: Impingement ensures a narrow arc of pathologic loading in adolescent hips with sequelae of Perthes Disease. Proper surgical interference when the hip is still in the pre-arthritic stage restores function and protects the young hip from early degenerative changes. METHODS: Osteochondroplasty at the femoral head neck junction and relative lengthening of the femoral neck by distal transfer of the greater trochanter was performed for 12 adolescents with combined intra articular/extra-articular impingement due to sequelae of Perthes disease in terms of coxa magna, coxa plana, coxa brevis, with an overriding greater trochanter. The safe surgical hip dislocation approach was performed in all cases. Patients were followed for an average of 24 months. RESULTS: The Harris hip scores improved from an average of 58 preoperatively (range 50 to 69) to 94 postoperatively (range 91 to 97) at latest follow up. The range of hip flexion improved from a preoperative value of 84.2 degrees (range, 60 to 105 degrees ) to value of 120.8 degrees (range, 95 to 130 degrees ). Changes in hip flexion averaged 28.6 degrees (range, 15 to 45 degrees ). Mean internal rotation increased to 26 degrees +/- 12 degrees , and abduction to 38 degrees +/- 11 degrees . Alpha angle improved to 40 degrees +/- 8 degrees . The mean of center trochanteric distance improved from an average of -18 mm to -1 mm. No osteonecrosis or chondrolysis was noted up to the time of the latest follow up. CONCLUSION: Elimination of narrow arc of pathologic loading due to impingement is the main advantage of the proposed surgical technique. Other advantages include increased abductor lever arm and restoration of hip joint range of motion with normalization of the loading conditions, and hence future development of degenerative arthritis and the anticipated need for a future joint replacement surgery could be prevented or delayed. Femoral head vascularity is well maintained with the proven safety of the presented surgical approach. PMID- 29182125 TI - Locked rigid antegrade intramedullary nailing of adolescent femoral fractures using a lateral trochanteric entry point. AB - The purpose of this study is to present our experience of treating adolescent femoral fractures using a locked intramedullary nail with a lateral trochanteric entry point. We retrospectively reviewed 15 femoral fractures in 13 adolescents who were treated in our unit between 2011 and 2014. Data collected included patient demographics, mechanism of injury, type of fracture, associated injuries, time to union and complications. A radiographic review was also undertaken. The mean time to radiological union in 14 out of the 15 fractures was 13 weeks (range, 10-20 weeks). One patient had a delayed union that required bone grafting and united finally at 30 weeks post injury. The mean difference in the neck shaft angle between the operated and non-operated side was 1.5 degrees (range : -10 to 10 degrees). No patients had infection or avascular necrosis. Five nails were removed after the fractures had healed without complications. Locked rigid intramedullary nailing of adolescent femoral fractures is a safe and effective treatment option when the lateral aspect of the greater trochanter is used as an entry point. PMID- 29182127 TI - Lower limb equalization with percutaneus epiphysiodesis of the knee joint area. AB - INTRODUCTION: Epiphysiodesis has become one of the most popular methods in the treatment of leg length discrepancy (LLD) due to its surgical simplicity, short hospitalization time, and a low risk of complications. PATIENTS AND METHODS: A retrospective analysis was performed on 34 patients treated for LDD with percutaneus epiphisiodesis of the distal femur and/or the proximal tibia. The mean discrepancy was 2.8 cm. The outcome evaluation method was based on Kemnitz et al. RESULTS: Based on the Kemnitz criteria, 23 (67.6%) patients experienced good results, while 2 (5.9%) satisfactory and 9 (26.5%) poor results. In 47% of patients, swellings of the knee joint were observed in the postoperative period. One serious complication - varus deformity of 10 degrees in femur occurred in the follow-up period. CONCLUSIONS: Percutaneous epiphysiodesis is a simple method of the LLD correction, with a low rate of complications and applicable in cases of late LDD diagnosis. PMID- 29182126 TI - A comparison of ketamine sedation and general anaesthesia for manipulation of paediatric forearm fractures. AB - The purpose of the study was to compare the use of ketamine sedation and general anaesthesia for manipulation of paediatric wrist and forearm fractures. A retrospective analysis was performed of patients under 16 years treated at our centre between October 2014 and October 2015. Exclusion criteria were open fractures and fractures with complete displacement. Outcomes measured were fracture reduction, the quality of the cast, fracture redisplacement, further surgical intervention and use of theatre time. 66 children were manipulated over the study period; 31 received ketamine sedation and 35 general anaesthesia. No statistically significant difference was found in the rate of re-intervention (p=0.48), quality of reduction (p=0.39), quality of cast (p=0.14 and p=0.21), or redisplacement (p=0.87). Those undergoing general anaesthesia used on average 50 minutes of theatre time and one third required an overnight admission. We conclude that ketamine sedation achieves comparable treatment outcomes to general anaesthesia whilst using fewer resources. PMID- 29182128 TI - Management of birth-associated subtrochanteric femur fractures. AB - In daily clinical practice most orthopedic surgeons suffer from doubt about treatment of rare injuries. The aim of this study is to enlighten the management of birth related femoral subtrochanteric fractures of neonates. Four birth related femoral subtrochanteric fractures of neonates were treated and followed up. Difficult caesarian breech delivery seems to be a risk factor. All patients were treated with Pavlik harness and union was achieved by the fourth week. None of the patients suffer any angulation or limb length discrepancy. Adequate management of this type of fractures lead to good results. PMID- 29182129 TI - Anatomical and functional evaluation of diaphyseal femoral fractures in children under 6 years old. AB - Objective : The aim of this study is to evaluate both the anatomical and functional consequences of our treatment protocol of diaphyseal femoral fractures in children under 6 years old Methods : We conducted a retrospective analysis of a series containing 50 children in Strasbourg University Hospital whom had traumatic diaphyseal femoral fractures and underwent conservative treatment by traction followed by casting with a mean follow-up period of 25 months. Results : All fractures healed without complications i.e. gait disorders, back pain and limitation of activity. Results showed a significant correlation between the initial varus angulation and shortening which could influence the final remodeling result within the first 24 months. Using the Receiver Operating Characteristic curve, we developed the Initial Displacement Index on Traction (IDIT) which is the sum of both the initial varus in degrees and the initial shortening in millimeters. Conclusion : The treatment by initial traction followed by a cast for childrens <= 6 years old gives clinical and radiological results comparable with those reported for immediate casting method. The hospitalization period is longer in the traction method but with less exposure to general anesthesia (GA) and risks of secondary displacements. PMID- 29182130 TI - Correlation of Pirani score and Foot bimalleolar angle in the treatment of idiopathic congenital talipes equino varus by Ponseti method in infants. AB - AIM: Correlation of Pirani score and Foot bimalleolar (FBM) angle in the treatment of idiopathic congenital talipes equino varus (CTEV) by Ponseti method in infants. MATERIAL AND METHODS: 35 feet with idiopathic CTEV deformity <1 year were prospectively treated by Ponseti method. Deformity evaluated each successive week of treatment by Pirani score and FBM angle. Feet were divided according to Pirani score in groups : one(0-2.0), two(2.5-4) and three(4.5-6). Correlation between mean Pirani score and mean FBM angle was evaluated every week and at follow up, firstly by using Pearson's and Spearman's correlation and then, after dividing data in groups by using ANOVA. RESULTS: Correlation between Pirani score and FBM angle was statistically significant(p value <0.05). CONCLUSION: Pirani score decreases and FBM angle increases with correction. Pirani score and FBM angle correlated in severity of deformity and correction achieved, thus FBM angle provides objective evidence of clubfoot deformity/improvement/deterioration. PMID- 29182131 TI - Lateral pinning versus others procedures in the treatment of supracondylar humerus fractures in children. AB - We compared results of lateral pinning procedure with crossed pinning, closed reduction, and open reduction in a retrospective review of 184 patients with displaced supracondylar humeral fractures. All patients had a minimum of 2 years follow-up (range 36-90 months). Patients were separated into 4 groups. Success was estimated by Flynn's criteria. We compared success of the lateral pinning to others procedures. Incidence of nerve palsy was recorded and compared. Esthetic effect of lateral pinning is significantly better than closed reduction (p=0.0007), but no significant difference was found comparing with cross pinning and open reduction. Elbow function was similar. Cross pinning procedure was followed with ulnar nerve palsy in ten patients (20.8%). There was 1 case (5%) of combined nerve palsy including ulnar, median and radial nerve after open reduction procedure. Lateral pinning is safe and effective method of therapy for Gartland type II and III supracondylar humeral fractures. PMID- 29182133 TI - Results of one-stage surgical treatment in children with Tonnis grade 4 developmental dysplasia of the hip: is it worse when it is bilateral? AB - This retrospective study compared the results of one-stage surgery of unilateral and bilateral Tonnis grade 4 hips (high dislocation in developmental hip dysplasia, DDH) : 41 hips, 30 patients. Mean follow-up was 56 months. Pelvic radiographs were evaluated at three time points. Acetabular inclination angle improved significantly in both groups. Results were satisfactory (Severin classes I-II) in 13 hips (68.5%) (unilateral group) and 21 hips (89.5%) (bilateral group). Functional evaluation (McKay classification) at final follow-up revealed satisfactory results in 94.8% (unilateral group) and 63.6% (bilateral group). One stage surgery is a reliable method for treating children with unilateral or bilateral DDH. PMID- 29182132 TI - Prevention of re-fractures of both bones of the forearm in children. AB - PURPOSE: The aim of this study was to observe if the re-fracture rate after forearm both bones was decreased by protecting the forearm with a preventive brace for 6 months following the fracture and by ceasing all physical activities. METHODS: We performed a retrospective study in 75 consecutive cases of diaphyseal fracture of both bone of forearms, in 52 boys and 23 girls aged from 6 months to 11 years. It concerned a first episode of fracture in 84% of cases and a re fracture in 17%. RESULTS: Re-fracture rate was 0% in the group where a protective brace was worn while it was 20% in the group without brace. CONCLUSIONS: Both the wearing of a protective brace and absence of sport for 6 months may decrease the re-fracture rate to 0%, if the patient is compliant by wearing it and by ceasing all physical activities. PMID- 29182134 TI - Titanium elastic nailing in femoral diaphyseal fractures in children of 6-14 years age. AB - BACKGROUND: Traditionally conservative methods were used in managing paediatric femoral diaphyseal fractures. There has been a renewed interest for operative treatment with Titanium elastic nail system (TENS) in the age group of 6-14 years. MATERIALS AND METHODS: This prospective study was done on 20 patients. Two titanium nails were used for stabilization. We followed them for maximum of two years. The results were evaluated using Flynn's scoring criteria. RESULTS: In our study we had fifteen males and five females with average age 10.35 years. Average time for fracture union was 9.0 weeks, full weight bearing 9.2 weeks, hospital stay 8.6 days and return to school at 10 weeks. The results were excellent in 14, good in 5 and poor in 1 patient. Most common complication was irritation at nail entry site. No delayed union or nonunion seen. CONCLUSION: Treatment of diaphyseal femoral fracture in selected pediatric patients by TENS is reasonably effective. PMID- 29182135 TI - Long-term outcome in displaced lateral humeral condyle fractures following internal screw fixation in children. AB - BACKGROUND: The aim of this study was to investigate the long-term clinical outcome following open reduction and internal screw fixation of displaced lateral condyle fractures (LCFs) of the distal humerus and compare the outcome of primary and secondary LCFs. METHODS: The clinical outcome in 31 children (mean age 5.8+/ 2.4 years) operated for primary or secondary LCFs was retrospectively analyzed by standardized clinical examination and compared using the Mayo score, Morger score, and Patients Satisfaction score. RESULTS: The scores did not differ significantly between the primary and secondary displacement groups (Mayo score: 99.3+/-3.3 vs. 100+/-0, p=0.852; Morger score: 3.8+/-0.5 vs. 3.9+/-0.3, p=0.852; Patients Satisfaction score: 3.7+/-0.6 vs. 3.9+/-0.3, p=0.546). Deficits in range of motion and joint axis deviation were minor (< 10 degrees ) and no elbow instabilities were observed. CONCLUSIONS: Surgical treatment of a secondary displaced LCF with open reduction and internal screw fixation leads to a favorable long-term outcome. The long-term outcome is similar between primary and secondary displaced LCFs. PMID- 29182136 TI - Titanium elastic nailing in femoral diaphyseal fractures in children of 6-14 years age. AB - PURPOSE: The purpose of this study is to report our experience of fractures in children riding Hoverboards. METHODS: We undertook a prospective review of all children attending our hospital who sustained fractures whilst riding a Hoverboard. Data such as patient demographics, type of fracture sustained, treatment received, complications and outcome were collected. RESULTS: Twelve children, 5 males and 7 females with ages ranging from 5.5 to 15.3 years were included in this study. All patients sustained upper limb fractures and the distal radius was the commonest fracture site (30%). Surgery was required in 6 (50%) out of the 12 patients because the respective fractures were displaced. No patient had any ongoing complaints or disability at the last clinic review. Conclusion : Children riding Hoverboards are predisposed to upper limb fractures and parents who purchase Hoverboards should be warned about this. PMID- 29182137 TI - Is Autologous Blood Transfusion cost effective in Adolescent Idiopathic Scoliosis? AB - The purpose of this study has been to evaluate the use of preoperative autologous blood donation (PABD) in the surgical treatment of adolescent idiopathic scoliosis (AIS). The surgical records of 37 AIS patients, Lenke type 1, were reviewed. Patients were classified according to whether they had entered the PABD (Program of Autologous Blood Donation) (25 patients) or had been rejected to join (12 patients non-donors). Both groups were comparable. All but one of the PADB patients (96%) as compared to only 2 non-donors patients (16.7%) required post operative transfusion. Moreover, 12 of the PABD patients (48%) did not require the whole stored blood. At discharge both groups had similar haemoglobin levels. The risk of transfusion was much higher in the PABD group. The patients in this group received blood even with high haemoglobin levels (>8 g/dl). Furthermore, 31.4% of the collected blood was never used. Therefore, PABD resulted in an increase in procedure costs and lead to unnecessary blood transfusions. PMID- 29182138 TI - Dealing with sub-trochanteric fracture in a child with osteopetrosis : A case report. AB - Osteopetrosis is a rare hereditary condition which may have autosomal recessive or autosomal dominant inheritance. Patients tend to present most commonly with fractures but involvement of cranial nerves and hematopoetic system is not uncommon. Patients with infantile and intermediate type tend to present more often with problems other than orthopaedic problems. While diagnosis can be made on the basis of radiographs, management needs to be customized for every patient. Non operative and operative management both have their advantages and disadvantages. We are here reporting a case of sub-trochanteric fracture in an eight-year-old child which was managed successfully with a dynamic hip screw (DHS). Surgery could be performed successfully by taking precautions during reduction, drilling and screw placement. At the latest follow up, which was after one and half years of surgery, the fracture had united well and the child faced no limitations of activities. Thus, open reduction and fixation with DHS can be considered as an effective management modality for pediatric sub-trochanteric fractures in osteopetrosis. PMID- 29182139 TI - A rare case of aneurymal bone cyst of cuboid bone in a 10-year-old girl. AB - Aneurysmal bone cysts (ABC) are rare and they represent 1- 1.4 % of all primary bone tumors. ABC of cuboid bone are extremely rare, especially in children. Very few cases have been reported in the literature since 1967. We present a case of pathological fracture of cuboid bone due to an aneurysmal cyst in a 10-year-old girl. Surgery was performed, which included open biopsy with aspiration and intralesional curettage . Bone defect was then filled in by fully synthetic cancellous bone graft substitute consisting of pure beta-tricalcium phosphate. Aneurysmal cyst of cuboid bone with pathological fracture could be successfully treated with pure beta-tricalcium phosphate as a bone graft substitute. This procedure is safe with excellent outcome.Follow up to nearly four years did not show any recurrence. PMID- 29182140 TI - Popliteal artery dissection presented 12 hours after admission for a Salter III fracture of proximal tibia. AB - A 16-year-old boy sustained a salter III fracture of the upper tibia following a motorcycle accident. Except for well localized knee pain, the patient did not have any other symptom. Repeated clinical examination did not reveal any absent peripheral pulse. Given the state of the fracture, anatomical reduction and screw fixation was planned in the operating room. Twelve hours after admission the patient was taken to the operating room. During the period preceding surgery he continued to have normal vascular clinical examinations. Further clinical assessment was performed in the operating room and remained to be normal. However after induction and upon extension of the lower limb, peripheral pulses in the affected side were abruptly lost. Urgent vascular exploration of the area showed a popliteal artery dissection necessitating a bypass graft to restore blood flow. We present a review of the literature alongside a case report showing how popliteal artery pathology in a similar context can present late and be for a period of time clinically undetectable.

AB - In this case report clinical and technical lessons including seven years follow up learned from a flexion-distraction, highly unstable cervical spine injury causing a complete separation of C6-7 cervical segment with tetraparesis in a 23 month-old boy, are presented. To our knowledge this is the only documented case in medical literature where adult size implants (cage, plate and lateral mass screw-rod system) were utilized for cervical combined anterior and posterior internal fixation in a child under the age of two years without implant-size related problems. Seven years after the injury the child attends elementary school, can operate a wheelchair manually, and can eat and write. Computed tomography control showed no failure of the hardware and fusion was later observed in the intervertebral space of the stabilized cervical segment, however adjacent segment syndrome occurred without deterioration of the patient's status. The decision on the mode of realignment and fixation to be made in such a case was difficult because there is no standard procedure for infants. PMID- 29182142 TI - An atypical case of elbow fracture Bilateral Capitellum Humeri Fracture in a Teenage. AB - Fractures of the capitellum are rare injures of the elbow rarely seen in adolescents. We report a case of a 14 year-old boy who sustained a bilateral Hahn Steinthal type fracture of his capitelum humeri. To our knowledge, such bilateral injury has not been reported before in teenagers. This paper reviews the literature regarding the epidemiology, classification and management of this rare pediatric capitellar fracture. PMID- 29182143 TI - Joint Modeling of Mixed Plasmodium Species Infections Using a Bivariate Poisson Lognormal Model. AB - Infectious diseases often present as coinfections that may affect each other in positive or negative ways. Understanding the relationship between two coinfecting pathogens is thus important to understand the risk of infection and burden of disease caused by each pathogen. Although coinfections with Plasmodium falciparum and Plasmodium vivax are very common outside Africa, it is yet unclear whether infections by the two parasite species are positively associated or if infection by one parasite suppresses the other. In this study, we use bivariate Poisson lognormal models (BPLM) to estimate covariate-adjusted associations between the incidence of infections (as measured by the force of blood-stage infections, molFOI) and clinical episodes caused by both P. falciparum and P. vivax in a cohort of Papua New Guinean children. A BPLM permits estimation of either positive or negative correlation, unlike most other multivariate Poisson models. Our results demonstrated a moderately positive association between P. falciparum and P. vivax infection rates, arguing against the hypothesis that P. vivax infections protect against P. falciparum infections. Our findings also suggest that the BPLM is only useful for counts with suitably large means and overdispersion. PMID- 29182144 TI - Chikungunya Virus Disease among Travelers-United States, 2014-2016. AB - Chikungunya virus is a mosquito-borne alphavirus that causes an acute febrile illness with severe polyarthralgia. The first local transmission of chikungunya virus in the Western Hemisphere was reported in December 2013. In the following year, the virus spread throughout much of the Americas and the number of cases among travelers increased substantially. We reviewed the epidemiology of chikungunya virus disease cases reported among U.S. travelers from 2014 to 2016. A total of 3,941 travel-acquired cases were reported from 49 states and the District of Columbia; 3,616 (92%) reported travel to other countries or territories in the Americas; the remaining 8% reported travel to Asia, Africa, or the Western Pacific. The most commonly reported travel destinations were the Dominican Republic, Puerto Rico, and Haiti. The largest number of cases (N = 2,780, 71%) had illness onset in 2014, followed by 2015 (N = 913, 23%) and 2016 (N = 248, 6%). Cases occurred in every month, but 70% of case-patients had illness onset from April to September, the months when mosquitoes are most likely to be active in the continental United States. Travel-acquired chikungunya cases will likely continue to occur and present a risk of introduction of the virus to locations in the continental United States. Clinicians and public health officials should be educated about the recognition, diagnosis, management, and timely reporting of chikungunya cases. PMID- 29182145 TI - Experimental Zika Virus Infection of Neotropical Primates. AB - The establishment of a sylvatic reservoir of Zika virus (ZIKV) in the Americas is dependent on the susceptibility of primates of sufficient population density, the duration and magnitude of viremia, and their exposure to the human mosquito-borne transmission cycle. To assess the susceptibility of squirrel (Saimiri sp.) and owl monkeys (Aotus sp.) to infection, we inoculated four animals of each species with ZIKV from the current epidemic. Viremia in the absence of detectible disease was observed in both species and seroconversion occurred by day 28. ZIKV was detected in the spleen of three owl monkeys: one at 7 days postinoculation (dpi) and two at 14 dpi. This study confirms the susceptibility to ZIKV infection of two Neotropical primate species that live in close proximity to humans in South America, suggesting that they could support a widespread sylvatic ZIKV cycle there. Collectively, establishment of a ZIKV sylvatic transmission cycle in South America would imperil eradication efforts and could provide a mechanism for continued exposure of humans to ZIKV infection and disease. PMID- 29182146 TI - Immunoproteasome functions explained by divergence in cleavage specificity and regulation. AB - The immunoproteasome (iP) has been proposed to perform specialized roles in MHC class I antigen presentation, cytokine modulation, and T cell differentiation and has emerged as a promising therapeutic target for autoimmune disorders and cancer. However, divergence in function between the iP and the constitutive proteasome (cP) has been unclear. A global peptide library-based screening strategy revealed that the proteasomes have overlapping but distinct substrate specificities. Differing iP specificity alters the quantity of production of certain MHC I epitopes but does not appear to be preferentially suited for antigen presentation. Furthermore, iP specificity was found to have likely arisen through genetic drift from the ancestral cP. Specificity differences were exploited to develop isoform-selective substrates. Cellular profiling using these substrates revealed that divergence in regulation of the iP balances its relative contribution to proteasome capacity in immune cells, resulting in selective recovery from inhibition. These findings have implications for iP-targeted therapeutic development. PMID- 29182147 TI - Rapid re-identification of human samples using portable DNA sequencing. AB - DNA re-identification is used for a broad suite of applications, ranging from cell line authentication to forensics. However, current re-identification schemes suffer from high latency and limited access. Here, we describe a rapid, inexpensive, and portable strategy to robustly re-identify human DNA called 'MinION sketching'. MinION sketching requires as few as 3 min of sequencing and 60-300 random SNPs to re-identify a sample enabling near real-time applications of DNA re-identification. Our method capitalizes on the rapidly growing availability of genomic reference data for cell lines, tissues in biobanks, and individuals. This empowers the application of MinION sketching in research and clinical settings for periodic cell line and tissue authentication. Importantly, our method enables considerably faster and more robust cell line authentication relative to current practices and could help to minimize the amount of irreproducible research caused by mix-ups and contamination in human cell and tissue cultures. PMID- 29182150 TI - Radiation protection for surgeons and anesthetists: practices and knowledge before and after training. AB - The use of radiological activity in the operating room (OR) and a regulatory decrease of the eye lens dose warrant an assessment of how medical staff are protected from radiation. This study aims to evaluate practices and knowledge in radiation protection (RP) for OR doctors before and after training. A descriptive study of surgeons and anesthetists in a French public hospital center was conducted in 2016. An ad hoc questionnaire concerning occupational practices and knowledge about RP was distributed before and one month after RP training. Among 103 doctors attending the training, 90 answered the questionnaire before the training. Results showed a lack of knowledge and good practice in RP. Most of the participants (86.7%) had never been trained in RP and recognized insufficient knowledge. Most of them (92.2%) wore a lead apron, 50.0% a thyroid-shield, 5.6% lead glasses, 53.3% a passive dosimeter and 17.8% an electronic dosimeter. None of them benefitted from collective protective equipment such as a ceiling suspended screen. The questionnaire following the training was completed by only 35 doctors. A comparison before and after training results showed an improvement in knowledge (scores of correct responses: 5.5/16 before and 9.5/16 after training) but not in RP good practices (scores of correct responses: 3.2/7 before and 3.3/7 after training). One training session appears to be insufficient to improve the application of the safety rules when x-rays are used. Communication needs to be improved regarding RP among anesthetists and surgeons, such as training renewal, workstation analysis in OR related to x-ray use and occupational medical follow-up. Otherwise, radiological risks in OR need to be given better consideration, such as radio-induced cataract risk. It is necessary to encourage the use of dosimeters and protective equipment and to strengthen access to lead glasses and collective protective equipment, such as ceiling suspended screens. All these recommendations ensure the received dose is reduced to as low as is reasonably achievable. PMID- 29182148 TI - A new genus of horse from Pleistocene North America. AB - The extinct 'New World stilt-legged', or NWSL, equids constitute a perplexing group of Pleistocene horses endemic to North America. Their slender distal limb bones resemble those of Asiatic asses, such as the Persian onager. Previous palaeogenetic studies, however, have suggested a closer relationship to caballine horses than to Asiatic asses. Here, we report complete mitochondrial and partial nuclear genomes from NWSL equids from across their geographic range. Although multiple NWSL equid species have been named, our palaeogenomic and morphometric analyses support the idea that there was only a single species of middle to late Pleistocene NWSL equid, and demonstrate that it falls outside of crown group Equus. We therefore propose a new genus, Haringtonhippus, for the sole species H. francisci. Our combined genomic and phenomic approach to resolving the systematics of extinct megafauna will allow for an improved understanding of the full extent of the terminal Pleistocene extinction event. PMID- 29182152 TI - Decoding of finger trajectory from ECoG using deep learning. AB - OBJECTIVE: Conventional decoding pipeline for brain-machine interfaces (BMIs) consists of chained different stages of feature extraction, time-frequency analysis and statistical learning models. Each of these stages uses a different algorithm trained in a sequential manner, which makes it difficult to make the whole system adaptive. The goal was to create an adaptive online system with a single objective function and a single learning algorithm so that the whole system can be trained in parallel to increase the decoding performance. Here, we used deep neural networks consisting of convolutional neural networks (CNN) and a special kind of recurrent neural network (RNN) called long short term memory (LSTM) to address these needs. APPROACH: We used electrocorticography (ECoG) data collected by Kubanek et al. The task consisted of individual finger flexions upon a visual cue. Our model combined a hierarchical feature extractor CNN and a RNN that was able to process sequential data and recognize temporal dynamics in the neural data. CNN was used as the feature extractor and LSTM was used as the regression algorithm to capture the temporal dynamics of the signal. MAIN RESULTS: We predicted the finger trajectory using ECoG signals and compared results for the least angle regression (LARS), CNN-LSTM, random forest, LSTM model (LSTM_HC, for using hard-coded features) and a decoding pipeline consisting of band-pass filtering, energy extraction, feature selection and linear regression. The results showed that the deep learning models performed better than the commonly used linear model. The deep learning models not only gave smoother and more realistic trajectories but also learned the transition between movement and rest state. SIGNIFICANCE: This study demonstrated a decoding network for BMI that involved a convolutional and recurrent neural network model. It integrated the feature extraction pipeline into the convolution and pooling layer and used LSTM layer to capture the state transitions. The discussed network eliminated the need to separately train the model at each step in the decoding pipeline. The whole system can be jointly optimized using stochastic gradient descent and is capable of online learning. PMID- 29182151 TI - Using convolutional neural networks to estimate time-of-flight from PET detector waveforms. AB - Although there have been impressive strides in detector development for time-of flight positron emission tomography, most detectors still make use of simple signal processing methods to extract the time-of-flight information from the detector signals. In most cases, the timing pick-off for each waveform is computed using leading edge discrimination or constant fraction discrimination, as these were historically easily implemented with analog pulse processing electronics. However, now with the availability of fast waveform digitizers, there is opportunity to make use of more of the timing information contained in the coincident detector waveforms with advanced signal processing techniques. Here we describe the application of deep convolutional neural networks (CNNs), a type of machine learning, to estimate time-of-flight directly from the pair of digitized detector waveforms for a coincident event. One of the key features of this approach is the simplicity in obtaining ground-truth-labeled data needed to train the CNN: the true time-of-flight is determined from the difference in path length between the positron emission and each of the coincident detectors, which can be easily controlled experimentally. The experimental setup used here made use of two photomultiplier tube-based scintillation detectors, and a point source, stepped in 5 mm increments over a 15 cm range between the two detectors. The detector waveforms were digitized at 10 GS s-1 using a bench-top oscilloscope. The results shown here demonstrate that CNN-based time-of-flight estimation improves timing resolution by 20% compared to leading edge discrimination (231 ps versus 185 ps), and 23% compared to constant fraction discrimination (242 ps versus 185 ps). By comparing several different CNN architectures, we also showed that CNN depth (number of convolutional and fully connected layers) had the largest impact on timing resolution, while the exact network parameters, such as convolutional filter size and number of feature maps, had only a minor influence. PMID- 29182149 TI - Multi-scale, multi-modal analysis uncovers complex relationship at the brain tissue-implant neural interface: new emphasis on the biological interface. AB - OBJECTIVE: Implantable neural electrode devices are important tools for neuroscience research and have an increasing range of clinical applications. However, the intricacies of the biological response after implantation, and their ultimate impact on recording performance, remain challenging to elucidate. Establishing a relationship between the neurobiology and chronic recording performance is confounded by technical challenges related to traditional electrophysiological, material, and histological limitations. This can greatly impact the interpretations of results pertaining to device performance and tissue health surrounding the implant. APPROACH: In this work, electrophysiological activity and immunohistological analysis are compared after controlling for motion artifacts, quiescent neuronal activity, and material failure of devices in order to better understand the relationship between histology and electrophysiological outcomes. MAIN RESULTS: Even after carefully accounting for these factors, the presence of viable neurons and lack of glial scarring does not convey single unit recording performance. SIGNIFICANCE: To better understand the biological factors influencing neural activity, detailed cellular and molecular tissue responses were examined. Decreases in neural activity and blood oxygenation in the tissue surrounding the implant, shift in expression levels of vesicular transporter proteins and ion channels, axon and myelin injury, and interrupted blood flow in nearby capillaries can impact neural activity around implanted neural interfaces. Combined, these tissue changes highlight the need for more comprehensive, basic science research to elucidate the relationship between biology and chronic electrophysiology performance in order to advance neural technologies. PMID- 29182153 TI - Characterization of the a-Si EPID in the unity MR-linac for dosimetric applications. AB - Electronic portal imaging devices (EPIDs) are frequently used in external beam radiation therapy for dose verification purposes. The aim of this study was to investigate the dose-response characteristics of the EPID in the Unity MR-linac (Elekta AB, Stockholm, Sweden) relevant for dosimetric applications under clinical conditions. EPID images and ionization chamber (IC) measurements were used to study the effects of the magnetic field, the scatter generated in the MR housing reaching the EPID, and inhomogeneous attenuation from the MR housing. Dose linearity and dose rate dependencies were also determined. The magnetic field strength at EPID level did not exceed 10 mT, and dose linearity and dose rate dependencies proved to be comparable to that on a conventional linac. Profiles of fields, delivered with and without the magnetic field, were indistinguishable. The EPID center had an offset of 5.6 cm in the longitudinal direction, compared to the beam central axis, meaning that large fields in this direction will partially fall outside the detector area and not be suitable for verification. Beam attenuation by the MRI scanner and the table is gantry angle dependent, presenting a minimum attenuation of 67% relative to the 90 degrees measurement. Repeatability, observed over two months, was within 0.5% (1 SD). In order to use the EPID for dosimetric applications in the MR-linac, challenges related to the EPID position, scatter from the MR housing, and the inhomogeneous, gantry angle-dependent attenuation of the beam will need to be solved. PMID- 29182154 TI - An automated, quantitative, and case-specific evaluation of deformable image registration in computed tomography images. AB - A prerequisite for adaptive dose-tracking in radiotherapy is the assessment of the deformable image registration (DIR) quality. In this work, various metrics that quantify DIR uncertainties are investigated using realistic deformation fields of 26 head and neck and 12 lung cancer patients. Metrics related to the physiologically feasibility (the Jacobian determinant, harmonic energy (HE), and octahedral shear strain (OSS)) and numerically robustness of the deformation (the inverse consistency error (ICE), transitivity error (TE), and distance discordance metric (DDM)) were investigated. The deformable registrations were performed using a B-spline transformation model. The DIR error metrics were log transformed and correlated (Pearson) against the log-transformed ground-truth error on a voxel level. Correlations of r ? 0.5 were found for the DDM and HE. Given a DIR tolerance threshold of 2.0 mm and a negative predictive value of 0.90, the DDM and HE thresholds were 0.49 mm and 0.014, respectively. In conclusion, the log-transformed DDM and HE can be used to identify voxels at risk for large DIR errors with a large negative predictive value. The HE and/or DDM can therefore be used to perform automated quality assurance of each CT-based DIR for head and neck and lung cancer patients. PMID- 29182155 TI - Stability and recovery of DNA origami structure with cation concentration. AB - We synthesized triangular and rectangular DNA origami nanostructures and investigated the stability and recovery of them under low cation concentration. Our results demonstrated that the origami nanostructures would melt when incubated in low cation concentration, and recover whilst kept in the concentration for less than 10 min. However, extending the incubation time would lead to irreversible melting. Our results show the possibility of application of DNA origami nanostructures for things such as a sensor for cation concentration response, etc. PMID- 29182157 TI - Preparation of well-distributed titania nanopillar arrays on Ti6Al4V surface by induction heating for enhancing osteogenic differentiation of stem cells. AB - Great effort has recently been devoted to the preparation of nanoscale surfaces on titanium-based implants to achieve clinically fast osteoinduction and osseointegration, which relies on the unique characteristics of the nanostructure. In this work, we used induction heating treatment (IHT) as a rapid oxidation method to fabricate a porous nanoscale oxide layer on the Ti6Al4V surface for better medical application. Well-distributed vertical nanopillars were yielded by IHT for 20-35 s on the alloy surface. The composition of the oxides contained rutile/anatase TiO2 and a small amount of Al2O3 between the TiO2 grain boundaries (GBs). This technology resulted in a reduction and subsequent increase of surface roughness of 26-32 nm when upregulating the heating time, followed by the successive enhancement of the thickness, wettability and adhesion strength of the oxidation layer to the matrix. The surface hardness also distinctly rose to 554 HV in the IHT-35 s group compared with the 350 HV of bare Ti6Al4V. The massive small-angle GBs in the bare alloy promoted the formation of nanosized oxide crystallites. The grain refinement and deformation texture reduction further improved the mechanical properties of the matrix after IHT. Moreover, in vitro experiments on a mesenchymal stem cell (BMSC) culture derived from human bone marrow for 1-7 days indicated that the nanoscale layers did not cause cytotoxicity, and facilitated cell differentiation in osteoblasts by enhancing the gene and osteogenesis-related protein expressions after 1-3 weeks of culturing. The increase of the IHT time slightly advanced the BMSC proliferation and differentiation, especially during long-term culture. Our findings provide strong evidence that IHT oxidation technology is a novel nanosurface modification technology, which is potentially promising for further clinical development. PMID- 29182156 TI - The effects of model composition design choices on high-fidelity simulations of motoneuron recruitment and firing behaviors. AB - OBJECTIVE: Computational models often require tradeoffs, such as balancing detail with efficiency; yet optimal balance should incorporate sound design features that do not bias the results of the specific scientific question under investigation. The present study examines how model design choices impact simulation results. APPROACH: We developed a rigorously-validated high-fidelity computational model of the spinal motoneuron pool to study three long-standing model design practices which have yet to be examined for their impact on motoneuron recruitment, firing rate, and force simulations. The practices examined were the use of: (1) generic cell models to simulate different motoneuron types, (2) discrete property ranges for different motoneuron types, and (3) biological homogeneity of cell properties within motoneuron types. MAIN RESULTS: Our results show that each of these practices accentuates conditions of motoneuron recruitment based on the size principle, and minimizes conditions of mixed and reversed recruitment orders, which have been observed in animal and human recordings. Specifically, strict motoneuron orderly size recruitment occurs, but in a compressed range, after which mixed and reverse motoneuron recruitment occurs due to the overlap in electrical properties of different motoneuron types. Additionally, these practices underestimate the motoneuron firing rates and force data simulated by existing models. SIGNIFICANCE: Our results indicate that current modeling practices increase conditions of motoneuron recruitment based on the size principle, and decrease conditions of mixed and reversed recruitment order, which, in turn, impacts the predictions made by existing models on motoneuron recruitment, firing rate, and force. Additionally, mixed and reverse motoneuron recruitment generated higher muscle force than orderly size motoneuron recruitment in these simulations and represents one potential scheme to increase muscle efficiency. The examined model design practices, as well as the present results, are applicable to neuronal modeling throughout the nervous system. PMID- 29182158 TI - Structural basis for specific flagellin recognition by the NLR protein NAIP5. AB - The nucleotide-binding domain- and leucine-rich repeat (LRR)-containing proteins (NLRs) function as intracellular immune receptors to detect the presence of pathogen- or host-derived signals. The mechanisms of how NLRs sense their ligands remain elusive. Here we report the structure of a bacterial flagellin derivative in complex with the NLR proteins NAIP5 and NLRC4 determined by cryo-electron microscopy at 4.28 A resolution. The structure revealed that the flagellin derivative forms two parallel helices interacting with multiple domains including BIR1 and LRR of NAIP5. Binding to NAIP5 results in a nearly complete burial of the flagellin derivative, thus stabilizing the active conformation of NAIP5. The extreme C-terminal side of the flagellin is anchored to a sterically constrained binding pocket of NAIP5, which likely acts as a structural determinant for discrimination of different bacterial flagellins by NAIP5, a notion further supported by biochemical data. Taken together, our results shed light on the molecular mechanisms underlying NLR ligand perception. PMID- 29182159 TI - Epigenetic Changes of FKBP5 as a Link Connecting Genetic and Environmental Risk Factors with Structural and Functional Brain Changes in Major Depression. AB - The gene for the glucocorticoid receptor regulator FK506 binding protein 5 (FKBP5) plays a role for risk, response to treatment, and changes in brain areas in major depressive disorder (MDD). Chronic stress is associated with lower methylation of FKBP5. Our aim was to investigate whether methylation of FKBP5 reflected exposure to childhood adversity in MDD and controls and whether it was associated with structure and function of emotional processing regions. FKBP5 intron 7 GR response element region methylation and rs1360780 allelic status were assessed from whole blood in 56 MDD adults and 50 controls. Using magnetic resonance imaging, we assessed gray matter concentration of selected areas and their function during valence recognition of emotional images. Childhood adversity was investigated using the Childhood Trauma Questionnaire. In MDD patients carrying the high-risk T allele of rs1360780, lower methylation of FKBP5 was predicted by childhood adversity (F=4.95, p=0.04). In all participants, lower FKBP5 intron methylation levels were associated with reduced gray matter concentration in the inferior frontal orbital gyrus bilaterally (Wald chi square=11.93, pFDR<0.01) and, in MDD, with its bilaterally higher activation during valence recognition (Wald chi-square=5.58, p=0.02). Activation of this region, regardless of side, was found to be lower in MDD compared to controls (Wald chi-square=3.88, p=0.049) and to be inversely correlated with depression severity (Wald chi-square=4.65, p=0.03). Our findings support the hypothesis that, in genetically predisposed individuals carrying a high-risk variant of the gene, childhood maltreatment might induce demethylation of FKBP5. This is in turn associated with structural and functional changes in the inferior frontal orbital gyrus, a relevant area for the clinical symptoms of MDD. PMID- 29182160 TI - Error-related Brain Activity as a Treatment Moderator and Index of Symptom Change during Cognitive-Behavioral Therapy or Selective Serotonin Reuptake Inhibitors. AB - Increased neural error monitoring, as measured by the error-related negativity (ERN), is a transdiagnostic neurobiological marker of anxiety. To date, little is known about whether the ERN can inform the choice between first-line anxiety disorder treatments and whether the ERN changes following treatment completion. The aim of the study was to therefore assess whether the ERN is a treatment moderator and index of symptom change during cognitive-behavioral therapy (CBT) or selective serotonin reuptake inhibitors (SSRIs). Participants included adult volunteers (M age=25.8+/-8.5; 67% female) with principal anxiety disorders (n=60) or no lifetime history of Axis I psychopathology (ie, healthy controls; n=26). A flanker task was used to elicit the ERN at baseline and 12 weeks later, following either CBT or SSRIs in the patient sample. Results indicated that baseline ERN was a significant treatment moderator such that a more enhanced baseline ERN was associated with greater reduction in anxiety symptoms within individuals who received CBT but not SSRIs. Results also revealed that the ERN increased pre- to post-treatment among patients randomized to SSRIs, but remained stable among patients randomized to CBT and healthy controls. Together, these novel findings highlight that ERN may help guide treatment decisions regarding engagement in CBT or SSRIs, especially among individuals with an enhanced ERN. The findings also suggest that SSRIs have the capacity to alter individual differences in the ERN, providing evidence that the ERN is not entirely static in patients with anxiety disorders.

PMID- 29182167 TI - Effects of nucleophilic ligands on the chain initiation efficiency of polar monomer polymerizations catalyzed by 2-methoxyethylaminobis(phenolate)yttrium complexes: a DFT study. AB - 2-Methoxyethylaminobis(phenolate)yttrium complexes Y(ONOOtBu)(Nu)(THF) have unique catalytic activity and selectivity toward the ring-opening polymerization (ROP) of beta-butyrolactone (BBL). Some of them also showed activity toward the group-transfer polymerization (GTP) of Michael-type monomers. These complexes with various nucleophilic ligands (Nu = CH2SiMe3, 1a; N(SiHMe2)2, 1b; OiPr, 1c) showed discrepant activity for ROP and GTP. The chain initiation of the ROP of BBL and the GTP of 2-vinylpyridine (2VP) catalyzed by these complexes is investigated by DFT calculations. The results indicate that, in the case of the ROP of BBL, less steric hindrance of the nucleophilic anionic ligand OiPr makes complex 1c have a higher chain initiation efficiency and thus a higher polymerization activity than 1a and 1b. In the case of the GTP of 2VP, the activity of 1a benefits from a good orbital match between the moieties of Y CH2SiMe3 and vinyl of 2VP. The origin of the experimentally observed inertness of 1b has also been elucidated. These results could add to the better understanding of the experimentally observed activity discrepancy and shed light on the development of such a catalysis system. PMID- 29182168 TI - Unimolecular decay strongly limits the atmospheric impact of Criegee intermediates. AB - Stabilized Criegee intermediates (SCI) are reactive oxygenated species formed in the ozonolysis of hydrocarbons. Their chemistry could influence the oxidative capacity of the atmosphere by affecting the HOx and NOx cycles, or by the formation of low-volatility oxygenates enhancing atmospheric aerosols known to have an important impact on climate. The concentration of SCI in the atmosphere has hitherto not been determined reliably, and very little is known about their speciation. Here we show that the concentration of biogenic SCI is strongly limited by their unimolecular decay, based on extensive theory-based structure activity relationships (SARs) for the reaction rates for decomposition. Reaction with water vapor, H2O and (H2O)2 molecules, is the second most important loss process; SARs are also proposed for these reactions. For SCI derived from the most common biogenic VOCs, we find that unimolecular decay is responsible for just over half of the loss, with reaction with water vapor the main remaining loss process. Reactions with SO2, NO2, or acids have negligible impact on the atmospheric SCI concentration. The ambient SCI concentrations are further characterized by analysis of field data with speciated hydrocarbon information, and by implementation of the chemistry in a global chemistry model. The results show a highly complex SCI speciation, with an atmospheric peak SCI concentrations below 1 * 105 molecule cm-3, and annual average SCI concentrations less than 7 * 103 molecule cm-3. We find that SCI have only a negligible impact on the global gas phase H2SO4 formation or removal of oxygenates, though some contribution around the equatorial belt, and in select regions, cannot be excluded. PMID- 29182169 TI - Molecular insights into the enhanced rate of CO2 absorption to produce bicarbonate in aqueous 2-amino-2-methyl-1-propanol. AB - 2-Amino-2-methyl-1-propanol (AMP), a sterically hindered amine, exhibits a much higher CO2 absorption rate relative to tertiary amine diethylethanolamine (DEEA), while both yield bicarbonate as a major product in aqueous solution, despite their similar basicity. We present molecular mechanisms underlying the significant difference of CO2 absorption rate based on ab initio molecular dynamics simulations combined with metadynamics. Our calculations predict the free energy barrier for base-catalyzed CO2 hydration to be lower in aqueous AMP compared to DEEA. Further molecular analysis suggests that the difference in free energy barrier is largely attributed to entropic effects associated with reorganization of H2O molecules adjacent to the basic N site. Stronger hydrogen bonding of H2O with N of DEEA than AMP, in addition to the presence of bulky ethyl groups, suppresses the thermal rearrangement of adjacent H2O molecules, thereby leading to lower stability of the transition state involving OH- creation and CO2 polarization. Moreover, the hindered reorganization of adjacent H2O molecules is found to facilitate migration of OH- (created via proton abstraction by DEEA) away from the N site while suppressing CO2 approach. This leads us to speculate that catalyzed CO2 hydration in aqueous DEEA may involve OH- migration through multiple hydrogen-bonded H2O molecules prior to reaction with CO2, whereas in aqueous AMP it seems to preferentially follow the one H2O-mediated mechanism. This study highlights the importance of entropic effects in determining both mechanisms and rates of CO2 absorption into aqueous sterically hindered amines.

AB - The chloride form of MgAl layered double hydroxide (hereafter MgAlCl) as an anion exchanger and the semisodic form of alpha-zirconium phosphate (hereafter ZrPNaH) as a cation exchanger are proposed as new cleaning agents for the removal of gypsum from ancient monuments. The ability of these exchangers to capture the calcium and sulphate ions of the gypsum powder was first investigated separately and then as a coupled system. MgAlCl/gypsum, ZrPNaH/gypsum and MgAlCl/ZrPNaH/gypsum mixtures were characterized by X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and dispersive X-ray spectroscopy (EDX). ZrPNaH in the form of a wet paste exhibited a rapid uptake of calcium from gypsum powder via Na+ and H+/Ca2+ cation exchange. Gypsum powder was also successfully dissolved by a wet paste of MgAlCl by exploiting the Cl-/SO42- anion exchange reaction. However, the dehydration of the paste favoured the reprecipitation of a secondary gypsum that was characterized by lower crystallinity and smaller particle size than the pristine gypsum. The combination of wet MgAlCl and ZrPNaH showed a synergic effect on the dissolution of gypsum and partially prevented the reprecipitation of gypsum in the dry paste. Finally, a preliminary test of the removal of gypsum crust grown on a sandstone sample was performed.

AB - Designing new two-dimensional (2D) materials with novel band topologies has continuously attracted intense interest in fundamental science and potential applications. Here, we report a unique 2D Mg2C monolayer featuring quasi-planar hexa-coordinate magnesium and hexa-coordinate carbon, which can be tuned from a metal to a semiconductor. The system has been studied using density functional theory, including electronic structure calculations and molecular dynamics simulations. In the freestanding state, the Mg2C monolayer behaves as a weak metal; however, by increasing the biaxial tensile strains, it can gradually be modulated to a gapless semimetal and then to a semiconductor. The Mg2C monolayer exhibits excellent dynamic and thermal stabilities and is also the global minimum of the 2D Mg2C system, implying the feasibility of its experimental synthesis. With unique band structures, the material may find applications in optoelectronics and electromechanics. PMID- 29182172 TI - Crystal phase transition of urea: what governs the reaction kinetics in molecular crystal phase transitions. AB - Because of their weak intermolecular forces and flexible molecular geometry, molecular crystals are renowned for their structural versatility (polymorphism) and the great difficulty in controlling the crystal form during synthesis. Despite its great importance in determining the final solid form (e.g. single crystal, polycrystal or amorphous), the kinetics of the crystal-to-crystal transformation between structures with different molecular packing has long been a fundamental challenge in both measurement and simulation. Here we report the first global potential energy surface (PES) for urea crystals obtained by stochastic surface walking global PES exploration. With the big data from thousands of crystal/amorphous forms, we, using exhaustive reaction pathway sampling, resolve the solid-to-solid transformation pathways between urea crystals from first principles. We demonstrate that the strong tendency to grow a large single crystal of urea can be attributed to the flat PES between major crystal forms that share the same hydrogen-bonding network pattern, where one crystal can transform to another facilely via crystal-to-crystal transition. Other crystal forms with distinct hydrogen-bonding network patterns can be excluded in crystallization due to their poor thermodynamic stability and high barrier of solid-to-solid transition. A general theory for predicting molecular solid transformation is proposed and illustrated in a simplified one-dimensional global PES, which is now obtainable from computational techniques established here.

AB - We report the successful synthesis of Mn doped CoN nanowires on a carbon fiber cloth substrate (CFC) by a two-step strategy, which can be used as an efficient and stable OER electrocatalyst under both alkaline and neutral conditions. Benefiting from enhanced electronic interaction, high active area and electrical conductivity, the Mn doped CoN nanowires/CFC exhibits enhanced kinetics and improved cycling stability for the OER under both alkaline and neutral conditions. To achieve a current density of 10 mA cm-2, the Mn doped CoN nanowires/CFC requires an overpotential of 265 mV in alkaline solution and 285 mV in neutral solution. PMID- 29182174 TI - Controllable synthesis of titanium nitride nanotubes by coaxial electrospinning and their application as a durable support for oxygen reduction reaction electrocatalysts. AB - Chemical and electrochemical corrosion of a support limits the corresponding catalyst's performance and lifetime. In this paper, uniform TiN nanotubes are synthesized via coaxial-electrospinning, thermal oxidation and nitridation. The average diameter of nanotubes can be facilely controlled by tuning the parameters of coaxial electrospinning. The TiN nanotubes are modified further with Pt nanoparticles as Pt/TiN NT electrocatalysts. After accelerated durability tests, the electrochemical surface area (ECSA) and mass activity of the Pt/TiN decrease by only 6% and 14% respectively, while those of the Pt/C decrease by 44% and 46.2% respectively. The enhanced activity is attributed to the strong interaction between the Pt nanoparticles and the TiN support, which is confirmed by the X-ray dispersive spectra of Pt 4f. PMID- 29182175 TI - Stable Fe nanomagnets encapsulated inside vertically-aligned carbon nanotubes. AB - Well-defined sized (5-10 nm) metallic iron nanoparticles (NPs) with body-centered cubic structure encapsulated inside the tip of millimeter-long vertically aligned carbon nanotubes (VACNTs) of uniform length have been investigated with high resolution transmission electron microscopy and soft X-ray spectroscopy techniques. Surface-sensitive and chemically-selective measurements have been used to evaluate the magnetic properties of the encapsulated NPs. The encapsulated Fe NPs display magnetic remanence up to room temperature, low coercivity, high chemical stability and no significant anisotropy. Our surface sensitive measurements combined with the specific morphology of the studied VACNTs allow us to pinpoint the contribution of the surface oxidized or hydroxidized iron catalysts present at the VACNT-substrate interface.

AB - Reported here is a unique non-interpenetrated open-framework metal chalcogenide built on a supertetrahedral [Fe4In16S35]14- cluster. The non-interpenetrated feature accompanied with the relatively large-sized cluster leads to a high extra framework volume.

AB - A mesoporous cationic Cr-MOF, termed FJI-C10, containing imidazolium moieties, Lewis acidic Cr3+ sites and free halogens is constructed for the first time by a topology-guided one-pot synthesis. FJI-C10 exhibits excellent performances in CO2 adsorption (20.2 wt% at 273 K and 1 bar) and chemical fixation of CO2 into cyclic carbonates without the use of co-catalyst under atmospheric pressure. PMID- 29182178 TI - Valence orbitals and local bond dynamics around N atoms of histidine under X-ray irradiation. AB - The valence orbitals of aqueous histidine under basic, neutral and acidic conditions and their X-ray induced transformations have been monitored through N 1s resonant inelastic X-ray scattering. Using density functional ab initio molecular dynamics simulations in the core-hole state within the Z + 1 approximation, core-excitation-induced molecular transformations are quantified. Spectroscopic evidence for a highly directional X-ray-induced local N-H dissociation within the scattering duration is presented for acidic histidine. Our report demonstrates a protonation-state and chemical-environment dependent propensity for a molecular dissociation, which is induced by the absorption of high energy photons. This case study indicates that structural deformations in biomolecules under exposure to ionizing radiation, yielding possible alteration or loss of function, is highly dependent on the physiological state of the molecule upon irradiation. PMID- 29182179 TI - Functionalized deltahedral Zintl complexes Ge9R3 (R = CF3, CN, and NO2): a new class of superhalogens. AB - The assembly of atoms leads to the formation of clusters. These clusters have a tendency to gain their stability by forming either cations or anions. Among the anionic clusters, Zintl ions with multiple negative charges are a special type of inorganic complex generally formed from group 13, 14 and 15 elements in the periodic table. On the other hand, superhalogens are neutral molecules which have high electron affinity. Between the two different types of molecules, the former stabilized in the neutral state by forming a phase with alkali metal atoms, while the latter prefers the anionic state. Using first principle calculations, we show that it is also possible to design superhalogens having a Zintl core by functionalizing with suitable ligands like CF3, CN and NO2. The vertical detachment energies of these complexes indicate that they can be classified as superhalogens. The stability of these complexes is explained in terms of the jellium model. Density of states, partial density of states and natural localized molecular orbitals (NLMO) of these molecules lend additional information on the structure and bonding of these complexes. PMID- 29182180 TI - Predicting the frequency of extreme air quality events. AB - A new method for predicting the frequency of extreme air quality events is proposed. The method is based on knowing the number of times a pollutant is measured at different concentrations during a period of data collection and fitting this data to a Weibull-type function. Extrapolation of the function to higher concentrations then allows the frequency of extreme events that did not occur during the collection period to be predicted, albeit with an unspecified uncertainty. Prediction of the frequency of events over a given concentration, which was exceeded during the period of data collection, has also been performed assuming Poisson statistics. The assumption of Poisson statistics enables the provision of an uncertainty statement to accompany the prediction. The methods are trialled on a data set of daily average PM10 mass concentrations recorded at Marylebone Road in London between 2007 and 2016, inclusive. Using the method it was predicted that a daily average PM10 mass concentration of over 100 MUg m-3, corresponding to the highest UK Daily Air Quality Index band, should be expected once in just over three years and this agreed well with real observations, demonstrating the utility of this new technique. PMID- 29182181 TI - Kinetic alteration of the 6Mg(NH2)2-9LiH-LiBH4 system by co-adding YCl3 and Li3N. AB - The 6Mg(NH2)2-9LiH-LiBH4 composite system has a maximum reversible hydrogen content of 4.2 wt% and a predicted dehydrogenation temperature of about 64 degrees C at 1 bar of H2. However, the existence of severe kinetic barriers precludes the occurrence of de/re-hydrogenation processes at such a low temperature (H. Cao, G. Wu, Y. Zhang, Z. Xiong, J. Qiu and P. Chen, J. Mater. Chem. A, 2014, 2, 15816-15822). In this work, Li3N and YCl3 have been chosen as co-additives for this system. These additives increase the hydrogen storage capacity and hasten the de/re-hydrogenation kinetics: a hydrogen uptake of 4.2 wt% of H2 was achieved in only 8 min under isothermal conditions at 180 degrees C and 85 bar of H2 pressure. The re-hydrogenation temperature, necessary for a complete absorption process, can be lowered below 90 degrees C by increasing the H2 pressure above 185 bar. Moreover, the results indicate that the hydrogenation capacity and absorption kinetics can be maintained roughly constant over several cycles. Low operating temperatures, together with fast absorption kinetics and good reversibility, make this system a promising on-board hydrogen storage material. The reasons for the improved de/re-hydrogenation properties are thoroughly investigated and discussed. PMID- 29182182 TI - Addition of a polyhistidine tag alters the regioselectivity of carbonyl reductase S1 from Candida magnoliae. AB - Studying enzymatic reductions of substrates with more than a single keto group is challenging, as the carbonyl reduction can create a vast array of regio- and stereoisomers. If used as reference compounds, regio- and stereopure hydroxy ketides could facilitate the characterization of reductases with unclear regio- and stereoselectivity. We have combined nonenzymatic and enzymatic reduction and oxidation steps to obtain all four regio- and stereoisomers of tert-butyl hydroxyoxohexanoates in high optical purity (enantiomeric ratio (er) of 99 : 1 for the delta-hydroxy-beta-keto isomers; er of >97 : 3 for the beta-hydroxy-delta keto isomers). Furthermore, we have prepared seven of the eight possible regioisomers and diastereomers of gamma-methylated hydroxyoxohexanoates. These 11 compounds allowed unraveling the complex stereoselectivity of beta,delta-diketo ester reductions catalyzed by carbonyl reductase S1 from Candida magnoliae (CMCR S1). Our analysis shows that the regio- and stereoselectivity of CMCR-S1 catalyzed reductions is highly sensitive toward modifications at the C-terminus of CMCR-S1: in addition to the expected delta-hydroxy product, the variant with a C-terminal His-tag also led to formation of beta-hydroxy by-products with high optical purity. PMID- 29182183 TI - Dendrimer-encapsulated nanoparticle-core micelles as a modular strategy for particle-in-a-box-in-a-box nanostructures. AB - The hierarchically controlled synthesis and characterization of self-assembling macromolecules and particles are key to explore and exploit new nanomaterials. Here we present a versatile strategy for constructing particle-in-a-box-in-a-box systems by assembling dendrimer-encapsulated gold nanoparticles (DENs) into dendrimicelles. This is realized by combining positively charged PAMAM dendrimers with a negative-neutral block copolymer. The number of particles per dendrimicelle can be controlled by mixing DENs with empty PAMAM dendrimers. The dendrimicelles are stable in solution for months and provide improved resistance for the nanoparticles against degradation. The dendrimicelle strategy provides a flexible platform with a plethora of options for variation in the type of nanoparticles, dendrimers and block copolymers used, and hence is tunable for applications ranging from nanomedicine to catalysis. PMID- 29182184 TI - Raman spectroscopy studies of the terahertz vibrational modes of a DUT-8 (Ni) metal-organic framework. AB - Low-frequency lattice vibrational modes have been discussed to play a crucial role in the phase transformation process of flexible metal-organic frameworks (MOFs). Therefore, Raman spectroscopy was applied to study the lattice dynamics of a pillared layer DUT-8(Ni) framework (DUT - Dresden University of Technology), existing in rigid and flexible forms. Both the open and the close pore phases could be unambiguously identified by breathing mode bands at 23 cm-1 and 60 cm-1 in the corresponding Raman spectra, showing the efficiency of the technique for monitoring the flexibility of MOF materials as well as the differences in the lattice vibrations of the two phases. Born-Oppenheimer Molecular Dynamics simulations showed that observed low-frequency bands indeed correspond to the oscillation of the breathing mode along the diagonals of the pore channels. Moreover, the directional character of low-frequency vibrations in the flexible version of DUT-8(Ni) could be visualized by the orientation dependent Raman spectroscopy experiment. PMID- 29182186 TI - Lateral sorting of chiral nanoparticles using Fano-enhanced chiral force in visible region. AB - Chiral gradient force allows a passive separation of an enantiomer since its direction is dependent on the handedness of its chiral entities. However, chiral polarisability is much weaker than electric polarisability. As a consequence, the non-chiral gradient force dominates over chiral force, which makes enantioselective sorting challenging. We present here, both numerically and analytically, that the chiral gradient force acting on chiral nanoparticles can overcome the non-chiral force when specimens are placed in a Fano-enhanced chiral gradient near-field using a plasmonic nanoaperture. Under circularly polarized light illumination, the interaction between the resonant modes of symmetric outer and asymmetric inner Au split-rings results in a splitting of the modal energies, which excites multipolar interference Fano resonances (FRs). This enables a local aperture between the two split-rings to possess very large optical chirality gradients while maintaining low gradients of electromagnetic energy density around the FRs from the visible region. By way of the lateral resultant force composed of both chiral and non-chiral gradient forces, we can accomplish a helicity-dependent transverse deflection of the chiral nanoparticles positioned above the aperture, which may offer a good platform for all-optical enantiopure compounds. PMID- 29182187 TI - New active leads for tuberculosis booster drugs by structure-based drug discovery. AB - The transcriptional repressor EthR from Mycobacterium tuberculosis, a member of the TetR family of prokaryotic homo-dimeric transcription factors, controls the expression of the mycobacterial mono-oxygenase EthA. EthA is responsible for the bio-activation of the second-line tuberculosis pro-drug ethionamide, and consequently EthR inhibitors boost drug efficacy. Here, we present a comprehensive in silico structure-based screening protocol that led to the identification of a number of novel scaffolds of EthR inhibitors in subsequent biophysical screening by thermal shift assay. Growth inhibition assays demonstrated that five of the twenty biophysical hits were capable of boosting ethionamide activity in vitro, with the best novel scaffold displaying an EC50 of 34 MUM. In addition, the co-crystal structures of EthR with four new ligands at resolution ranging from 2.1 to 1.4 A confirm the binding and inactivation mode, and will enable future lead development. PMID- 29182185 TI - Wearable sensors: modalities, challenges, and prospects. AB - Wearable sensors have recently seen a large increase in both research and commercialization. However, success in wearable sensors has been a mix of both progress and setbacks. Most of commercial progress has been in smart adaptation of existing mechanical, electrical and optical methods of measuring the body. This adaptation has involved innovations in how to miniaturize sensing technologies, how to make them conformal and flexible, and in the development of companion software that increases the value of the measured data. However, chemical sensing modalities have experienced greater challenges in commercial adoption, especially for non-invasive chemical sensors. There have also been significant challenges in making significant fundamental improvements to existing mechanical, electrical, and optical sensing modalities, especially in improving their specificity of detection. Many of these challenges can be understood by appreciating the body's surface (skin) as more of an information barrier than as an information source. With a deeper understanding of the fundamental challenges faced for wearable sensors and of the state-of-the-art for wearable sensor technology, the roadmap becomes clearer for creating the next generation of innovations and breakthroughs. PMID- 29182188 TI - Carbon cloth supported cobalt phosphide as multifunctional catalysts for efficient overall water splitting and zinc-air batteries. AB - Excellent performance and multifunctional electrocatalysts are of great importance for the development of renewable energy. Here, a multifunctional carbon cloth supported cobalt phosphide (CoP@CC) electrocatalyst was synthesized via a simple electrochemical deposition followed by subsequent phosphorization. This self-standing CoP@CC presents superior HER performance in both acid and alkaline media and excellent OER activity in an alkaline environment. When applied as both anode and cathode catalyst to overall water splitting, CoP@CC only required a low cell voltage of 1.68 V to drive a current density of 10 mA cm 2, making this catalyst a potential candidate in industrial application. Moreover, inspired by its satisfying ORR activity, CoP@CC was first used as the air-electrode in zinc-air batteries, which outputted an open-circuit potential of 0.6 V and a power density of ~30 mW cm-2.

AB - An indicator displacement assay has been adapted to detect the diol products of the aldol reaction between 4-nitrobenzaldehyde and hydroxyacetone in crude reaction mixtures. This provides a rapid colorimetric method of detecting product formation and thus evaluating potential catalysts, which is demonstrated using multiple catalytic peptides. PMID- 29182190 TI - [Association between socioeconomic status and survival after a first episode of myocardial infarction]. AB - BACKGROUND: A low socioeconomic status is associated with higher overall mortality rates. AIM: To assess the effect of socioeconomic inequalities on survival of patients hospitalized with a first myocardial infarction. MATERIAL AND METHODS: Analysis of hospital discharge and mortality databases of the Ministry of Health. Patients aged over 15 years discharged between 2002 and 2011 with a first myocardial infarction (code I-21, ICD-10) were identified. Their survival was verified with the mortality registry. Survival from 0 to 28 and from 29 to 365 days was analyzed. Socioeconomic status was determined using the type of health insurance, stratified as public insurance (low and medium status) and private insurance (high status). Prais-Winsten trend (P-W) and Cox survival analyses were done. RESULTS: We analyzed 59,557 patients (69% males). Sixty three percent were of low socioeconomic status, 19% medium and 18% high. Between 2002 and 2011 the increase in survival was higher among patients of low socioeconomic status, mainly in women (P-W coefficients 0.58:0.31-0.86 in men and 1.12:0.84 1.41 in women for 0-28 days survival and 0.24:0.09-0.39 in men and 0.48:0.37-0.60 in women for 29-365 days survival, respectively). However, age and year of hospitalization adjusted analysis showed a higher mortality risk among patients of low socioeconomic status at 0-28 days (HR 1.67:1.53-1.83 for men and 1.49:1.34 1.66 for women) and at 29-365 days (HR 2.30:1.75-2.71 for men and 1.90:1.56-1.85 for women). CONCLUSIONS: Survival after a myocardial infarction improved in the last decade especially in patients of low socioeconomic status. However, subjects of this stratum continue to have a higher mortality. PMID- 29182191 TI - [Association of active commuting with obesity: findings from the Chilean National Health Survey 2009-2010]. AB - BACKGROUND: Active commuting is associated with a lower risk for obesity in developed countries. AIM: To investigate the association between active commuting and obesity risk in Chile. MATERIAL AND METHODS: Active commuting was measured using the Global Physical Activity Questionnaire (GPAQ v2) in 5,293 participants from the Chilean National Health Survey 2009-2010. Body mass index (BMI) and waist circumference (WC) were the study outcomes. The association between active commuting and obesity was investigated using linear and logistic regression analysis. RESULTS: Thirty four percent of responders [95% confidence intervals (CI): 32.6-35.1] were passive commuters. Active commuters had a lower BMI and WC than their passive counterparts. Thirty minutes increment in active commuting were associated with a -0.20 kg.m-2 lower BMI [95% CI: -0.33 to -0.07, p < 0.01] and a -076 cm lower WC [95% CI: -1.08 to -0.43, p < 0.01]. The odds of having a BMI > 25 kg.m-2 was 0.93 [95% CI: 0.88 to 0.98, p = 0.01] per every 30 minutes' increment in active commuting, whereas the odds for central obesity was 0.87 [95% CI: 0.82 to 0.92, p < 0.01]. CONCLUSIONS: Active commuting is associated with a lower adiposity and lower risk for obesity in Chilean adults. PMID- 29182192 TI - [Effects of high-intensity interval training and nutritional education in patients with type 2 diabetes]. AB - BACKGROUND: High-intensity interval training (HIIT) improves cardiometabolic markers, but its effects on the quality of life of patients with type 2 diabetes (T2D) is not well known. AIM: To determine the effects of a 12-week HIIT exercise program on cardiometabolic and quality of life variables of T2D patients. MATERIAL AND METHODS: Nine T2D women were assigned to a HIIT + nutritional education (GE) and 10, to a nutritional education alone group (GC). At baseline and after each intervention, anthropometric and body composition parameters using bio-impedance were assessed, and a blood sample was obtained to measure serum lipid levels, blood glucose and glycated hemoglobin. Quality of life was assessed using the SF-12 questionnaire adapted for the Chilean population. RESULTS: There were no significant changes on the lipid profile variables in the GE group, although HDL cholesterol was increased significantly (p < 0.05) in the GC group. Total fat mass was decreased in the GE group from 43.5 +/- 1.5 to 41.9 +/- 1.5%, p < 0.01. Fasting glucose and glycated hemoglobin decreased in the GE group. There was a significant correlation between the decrease in total fat mass and that of glycated hemoglobin. There were significant increases in quality of life parameters; physical function, physical role, pain, general health, vitality, emotional role, mental health, and social function in the GE but not in the GC group. CONCLUSIONS: A 12-week program of HIIT plus nutritional education improves cardiometabolic and quality of life parameters on type 2 diabetics. PMID- 29182193 TI - [Microarrays in 236 patients with neurodevelopmental disorders and congenital abnormalities]. AB - BACKGROUND: In 20% of neurodevelopmental disorders (NDD) and congenital abnormalities (CA) the cause would be a genomic imbalance detectable only by chromosomal microarrays (CMA). AIM: To analyze the results of CMA performed at the INTA Laboratory of Molecular Cytogenetics, during a period of four years in patients with NDD or CA. MATERIAL AND METHODS: Retrospective study that included all CMA reports of Chilean patients. Age, sex, clinical diagnosis and origin were analyzed, as well as the characteristics of the finding. The percentage of cases diagnosed by CMA was calculated considering all patients with pathogenic (PV) or probably pathogenic variants (VLP). Finally, we studied the association between patients' characteristics and a positive CMA outcome. RESULTS: A total of 236 reports were analyzed. The median age was 5.41 (range 2.25-9.33) years, and 59% were men. Ninety chromosomal imbalances were found, which corresponded mainly to deletions (53.3%), with a median size of 1.662 (range 0.553-6.673) Megabases. The diagnostic rate of CMA in Chilean patients from all over the country was 19.2%. There was a close relationship between the patient's sex and the detection of VLP/VP (p = 0.034). CONCLUSIONS: Our diagnostic rate and the association between female sex and a higher percentage of diagnosed cases are concordant with other international studies. Therefore, CMA is a valid diagnostic tool in the Chilean population. PMID- 29182195 TI - [Assessment of a Chilean Spanish version of the Patient Assessment of Chronic Illness Care Questionnaire]. AB - BACKGROUND: The Patient Assessment of Chronic Illness Care (PACIC) questionnaire is a widely used instrument to assess chronic disease care from a patient's perspective. AIM: To adapt the PACIC questionnaire to Chilean Spanish and to evaluate the psychometric properties of the translation. MATERIAL AND METHODS: Descriptive, cross-sectional design with exploratory and confirmatory factor analysis. The PACIC questionnaire was applied, throughout an external client, to 200 users who received health care at the cardiovascular program in a Family Health Center in Concepcion, Chile. RESULTS: The confirmatory factor analysis did not show a good adjustment with the proposed structure in the original instrument. An exploratory factor analysis revealed five factors explaining 58% of total data variability. The distribution of the factor-items of the original questionnaire underwent some modifications, which are explained when analyzing the theoretical construct. A good reliability of the global scale was obtained (Cronbach's alpha 0.886). CONCLUSIONS: The PACIC questionnaire, Chilean version does not replicate the proposed structure of the original questionnaire. Therefore, further research about its validity, incorporating a higher number or diversity of participants is recommended. PMID- 29182194 TI - [Performance of an abbreviated mini mental examination to detect dementia in older people]. AB - BACKGROUND: The usefulness of the abbreviated Mini-Mental State Examination included in the Chilean Functional assessment of elderly people (MM-SE-EFAM) to detect Dementia has not been determined. AIM: To assess the performance of the MMSE-EFAM to detect dementia. MATERIAL AND METHODS: We studied a non probabilistic sample of subjects older than 65 years who had been assessed by the MMSE-EFAM in a Chilean primary care center during a period of 6 months. Patients underwent clinical evaluation by a neurologist blinded to MMSE-EFAM score, to establish the diagnosis of dementia using DSM-IV-TR criteria. Besides, the full Mini-Mental State Examination (MMSE) was applied. RESULTS: The clinical diagnosis of Dementia was established in 13 of the 54 peoples evaluated. MMSE-EFAM had a sensitivity of 30.8% (95% confidence intervals (CI); 9-61.4) and a specificity of 90.2% (95% CI; 76.9%-97.3%), while MMSE had a sensitivity of 84.6% (95% CI; 54.6 98.1) and a specificity of 58.5% (95% CI; 42.1-73.7). In a receiver operating characteristic (ROC) curve analysis, the areas under the curve (AUC) were 0.77 (95% CI; 0.61-0.93) and 0.82 (95% CI; 0.70-0.95) for MMSE-EFAM and MMSE, respectively. Socio-demographic variables did not influence test performance in both cases. CONCLUSIONS: MMSE-EFAM has a low sensitivity to detect patients with Dementia and it is not an effective screening tool. These results are in agreement with the evidence and international guidelines that do not support the use of cognitive screening tools to detect dementia in the older general population. PMID- 29182196 TI - [Attributes and features of a community health model from the perspective of practitioners]. AB - BACKGROUND: The Family and Community Health Model is based on three essential principles: user-centered care, comprehensive care and continuity of care. AIM: To describe the attributes and characteristics of the guiding principles of the Family and Community Health Model (FHM) from the perspective of primary care experts. MATERIAL AND METHODS: This was a qualitative study. An electronic Delphi was conducted with 29 national experts on primary care. RESULTS: The experts agree that user centered care must be based on a psycho-social model integrating the multiple factors that influence health problems. It also must integrate patients' individual features, family and environmental issues. The proposed actions promote shared decision making. To promote integral care, anticipatory guidelines should be expanded and health care of patients with chronic conditions should be improved. Continuity of care should be promoted increasing working hours of medical centers and easing access to integrated electronic medical records, thereby generating efficient links between the different care levels. CONCLUSIONS: The results of the study can guide the clinical and administrative management of health teams, allowing the strengthening of primary health care according to the local realities. PMID- 29182197 TI - [Nurses' workload in hemodialysis units]. AB - BACKGROUND: Knowing nurses' workload in hemodialysis units allows a better organization of human resources. AIM: To determine nurses' workload according to dependence and risk profiles of patients undergoing chronic hemodialysis. MATERIAL AND METHODS: One hundred fifty one patients from five hemodialysis units were selected and categorized in terms of dependence and risk using the instrument "Care according to dependence and risk in hemodialysis (CUDYR-DIAL). Nurses' activities for direct and indirect care and the time taken to complete those activities were measured. RESULTS: Per patient, nurses used 36.5 +/-10.7 min for direct and 23.6 min for indirect care. The time required for direct care of patients at high risk with partial dependence and at high risk and partial self-sufficiency was 41.2 and 40.3 minutes respectively. CONCLUSIONS: During a dialysis session, nurses occupy 60% of their time providing direct care, mainly directed to patients categorized as being of high risk-partial dependence and high risk-partial self-sufficiency. PMID- 29182198 TI - [Abnormal expansion of C9orf72 gene in familial frontotemporal dementia]. AB - Frontotemporal Dementia (FTD) and Motor Neuron Disease (MND) may share similar pathogenic mechanisms. An abnormal hexanucleotide expansion in C9orf72 gene is the most common genetic abnormality of these conditions and explains their concurrence in the same family. We report a 77-year-old female presenting with non-fluent aphasia leading to mutism and a mild Parkinsonism. A magnetic resonance imaging showed a severe atrophy of frontal and temporal lobes. Several family members of the patient suffered of atypical Parkinsonism, lateral amyotrophic sclerosis and dementia. We identified an abnormal hexanucleotide expansion in the C9orf72 gene in the proband. To the extent of our knowledge, this is the first time that this diagnosis is confirmed in our country. The knowledge of the genetic basis of neuro degenerative disorders improves diagnosis and opens expectatives for future treatments of these disabling conditions. PMID- 29182199 TI - [An analysis of essential health research in Chile]. AB - Essential research studies of health problems affecting the majority of the population, aiming at actions that are feasible to be taken, efficiently and effectively implementing there and seeking solutions to unsolved problems. This is a complex process, which requires long lasting participation and coordinated interaction between different relevant sectors, namely the academic world, health policymakers and health-related industries. An analysis of essential health research in Chile is presented, considering factors such as shared efforts between the academic and health care sectors and the role of the Ministry of Health in research promotion. The following suggestions are made: 1) The Ministry of Health, along with universities, should stimulate, guide and monitor research activities that enrich and update the work on priority health issues; 2) To strengthen the capacity building of clinical or public health specialists by training them in applied research within medical centers, mainly teaching centers; 3) To assess the performance of National Fund for Health Research and Development (FONIS) and, if necessary, increase its resources to stimulate applied research in health; 4) To establish priorities for essential research, more specific than those proposed in 2010; 5) To reactivate the National Council for Health Research (CONIS) as an autonomous entity that coordinates applied research within the Ministry of Health.

AB - Polycystic ovarian syndrome (PCOS) is an endocrine and metabolic dysfunction, highly prevalent in women in their reproductive years. Hyperandrogenism, oligo ovulation, polycystic ovarian morphology are the main features of this syndrome. PCOS is a genetic disorder with a multifactorial etiology and has a strong link with environmental components. It is frequently associated with obesity and insulin resistance. Recently, epigenetic mechanisms have been involved in the pathogenesis of PCOS. Several studies showed that methylation in DNA and miRNAs is altered in women with PCOS in blood, serum, adipose tissue, granulose cells and theca. This evidence indicates that women with PCOS have a different epigenetic regulation, which might be triggered by an adverse intrauterine environment or by postnatal environmental elements such as diet and or obesity.

AB - During the first Modern Era (15th-17th c.), bodily health and expressions of physiognomy were explained under the doctrine of humors. This doctrine -based on Corpus Hipocraticum-established a close relation between humors (blood, yellow bile, phlegm, and black bile), qualities (dry, moist, warm, and cold) and the elements (water, air, earth, and fire). One of these humors -black bile-, commonly a hallmark of the melancholic temperament, was associated to the complexion and nature of American Indians. This accusation was legitimized by the empirical examination of the physiognomy of a subject that was melancholic, sad and pusillanimous. In this article, we describe, based on the analysis of colonial texts (16th-17th c.), how the essential premises of the humor theory were transferred to the New World and in particular and how the Indian complexion was defined through the examination of subjects plagued by black humor and phlegm. With this, we determine the way these individuals -referred as 'Indians'- were inscribed in medical knowledge, during the global spread of the Hippocratic Galenic postulates. PMID- 29182202 TI - [The educational context to train health care professionals. A qualitative approach]. AB - BACKGROUND: There are differences in the educational context in Health Sciences, between clinical and non-clinical teachers. Therefore, the didactic and reflexive peculiarities of both educational scenarios should be analyzed. AIM: To describe the conditions of the educational context in Health Sciences for the practice of the teaching role in a Chilean university. MATERIAL AND METHODS: Qualitative study, performed according to Grounded Theory of Strauss and Corbin. Thirty one teachers from six health sciences programs were selected according to Patton's maximum variation criterion and contacted personally, after an informed consent process. Semi-structured interviews and focus group were performed, analyzed by open coding, using the constant comparison method, with the Atlas-ti 7.5.2 software. RESULTS: Six conditions of the educational context that can support the teaching role in these careers emerged. Namely, a clinical field suited for patient attention and teaching, classrooms designed for the new educational models, number of students in the classrooms and clinical settings, insertion programs for teachers' training, teachers' coordination and economic resources of the program. CONCLUSIONS: Health Sciences programs are developed in a complex educational context, having to articulate diverse elements to train professionals. Therefore, it is fundamental to understand the conditions of the educational context that can favor the practice of the teaching role, thus generating improvements in teaching-learning process. PMID- 29182203 TI - [Self-directed learning and academic background of 2010 to 2014 cohorts of medical students]. AB - BACKGROUND: The widespread growth of higher education is increasing the heterogeneity of university students in terms of socioeconomic characteristics, academic story and cultural background. Medical schools are not an exception of this phenomenon. AIM: To compare the academic background and self-directed learning behavior of students who entered to a public medial school between 2010 and 2014. MATERIAL AND METHODS: A non-probabilistic sample of 527 medical students aged between 17 and 29 years (60% men), was studied. Their academic information was collected from the University data base; they answered the Self directed learning readiness scale of Fisher. RESULTS: Students from the 2014 cohort had higher high school grades than their counterparts. The scores in mathematics of the Scholarship Aptitude Test (SAT) were higher in the cohorts of 2010 and 2011. Those of the sciences test were superior in the 2013 cohort. The 2014 cohort had the lower general score of self-directed learning behaviors. CONCLUSIONS: The lower SAT and self-directed learning scores of the students entering medical school in 2014, indicate the progressive increase in the heterogeneity of Medical students.

AB - Symptoms of hypopituitarism are usually chronic and nonspecific, but rarely the disease can have acute and life threatening manifestations. We report a 53 years old female with a pituitary adenoma that was admitted to our hospital because of syncope. The electrocardiogram showed sinus bradycardia with a prolonged QT interval. Frequent runs of non-sustained polymorphic ventricular tachycardia were noted on telemetry. The patient had a history of severe acute headaches in the previous days and laboratory tests revealed severe secondary hypothyroidism, adrenal insufficiency and a decrease in pituitary hormones. A magnetic resonance imaging of the head showed changes in the size and contrast enhancement of the adenoma. A diagnosis of hypopituitarism secondary to pituitary apoplexy was made and treatment with hydrocortisone and, subsequently, levothyroxine was started. Hormonal disorders such as hypothyroidism, adrenal insufficiency or hypopituitarism should be considered as unusual causes for reversible cardiomyopathy, long QT syndrome and ventricular arrhythmias.

AB - We report a 73-year-old female patient with Castleman's disease coexistent with large B cell type non-Hodgkin's lymphoma in a right axillary lymphadenopathy. An excisional biopsy was performed: microscopically, the lymph node revealed the presence of numerous plasma cells and small lymphoid cells characteristic of Castleman's disease. An analysis of another portion of the specimen revealed lymphoid cells with large abnormal nuclei gathered locally that were CDD 79+, CD 38+ and MUM-1+ as well as positive for Kaposi sarcoma-associated herpesvirus and negative for Epstein Barr virus encoded RNA-1 (EBER).

AB - McKittrick-Wheelock syndrome is caused by chronic water and electrolyte hypersecretion from an intestinal tumor, usually a villous adenoma, located in the rectum or sigmoid. Patients often have dehydration, hypovolemic shock and kidney failure associated with hypokalemia, hyponatremia, hypochloremia and metabolic acidosis. We report a 62-year-old male, suffering chronic diarrhea for eight years who was admitted after a syncope. He had severe hypokalemia, hyponatremia, metabolic acidosis, hypovolemia and acute renal failure. After his metabolic disorders were corrected, a colonoscopy showed a large rectosigmoid tumor with the characteristics of a villous adenoma. During the follow up after the complete tumor resection, the patient has remained asymptomatic.

PMID- 29182210 TI - The role of point-of-care ultrasound in intra-abdominal hypertension management. AB - BACKGROUND: Intra-abdominal hypertension is a common complication in critically ill patients. Recently the Abdominal Compartment Society (WSACS) developed a medical management algorithm with a stepwise approach according to the evolution of the intra-abdominal pressure and aiming to keep IAP <= 15 mm Hg. With the increased use of ultrasound as a bedside modality in both emergency and critical care patients, we hypothesized that ultrasound could be used as an adjuvant point of-care tool during IAH management. This may be particularly relevant to the first and second basic stages of the algorithm. The objective of this paper is to test the use of POCUS as an adjuvant tool in the management of patients with IAH/ACS. METHODS: Seventy-three consecutive adult critically ill patients admitted to the surgical intensive care unit (ICU) of a single urban institution with risk factor for IAH/ACS were enrolled. Those who met the inclusion criteria were allocated to undergo POCUS as an adjuvant tool in their IAH/ACS management. RESULTS: A total of 50 patients met the inclusion criteria and were included in the study. The mean age of study participants was 55 +/- 22.6 years, 58% were men, and the most frequent admission diagnosis was post-operative care following abdominal intervention. All admitted patients presented with a degree of IAH during their ICU stay. Following step 1 of the WSACS IAH medical management algorithm, ultrasound was used for NGT placement, confirmation of correct positioning, and evaluation of stomach contents. Ultrasound was comparable to abdominal X-ray, but shown to be superior in determining the gastric content (fluid vs. solid). Furthermore, POCUS allowed faster determination of correct NGT positioning in the stomach (antrum), avoiding bedside radiation exposure. Ultrasound also proved useful in: 1) evaluation of bowel activity; 2) identification of large bowel contents; 3) identification of patients that would benefit from bowel evacuation (enema) as an adjuvant to lower IAP; 4) and in the diagnosis of moderate to large amounts of free intra-abdominal fluid. CONCLUSION: POCUS is a powerful systematic ultrasound technique that can be used as an adjuvant in intra-abdominal hypertension management. It has the potential to be used in both diagnosis and treatment during the course of IAH. PMID- 29182211 TI - Assessment of hypovolaemia in the critically ill. AB - Assessment of the intravascular volume status of patients is one of the most challenging tasks for the intensive care clinician. It is also one of the most important skills in intensive care management as both hypervolaemia and hypovolaemia lead to increased morbidity and mortality. The assessment of hypovolaemic patients is aided by several clinical signs, laboratory investigations, and a multitude of haemodynamic monitoring systems. This review aims to outline the definitions, pathophysiology, and various assessment techniques (both old and new) employed by intensivists on the critically ill patient. PMID- 29182212 TI - A Randomised Controlled Trial of a Universal Bonding Agent at Three Years: Self Etch vs Total Etch. AB - General dental practice is increasingly being recognised as the ideal situation for the conduct of clinical trials into the longevity of restorations. The aim of this study was to investigate the survival of 64 nanofilled resin composite (Filtek Supreme XTE) restorations placed principally in loadbearing cavities using a Universal dentine bonding agent (Scotchbond Universal), in five UK dental practices by members of the UK-based practice-based research group, the PREP Panel. A split mouth design was used, comprising patients who required two restorations, with one of the restorations receiving a total etch approach using phosphoric acid and the other being placed using a self-etch approach. The results indicated good performance of the restorations examined, with no difference, in terms of marginal characteristics, between the restorations which received total etching and those which did not. PMID- 29182213 TI - The Effect of Core and Veneering Design on the Optical Properties of Polyether Ether Ketone. AB - This study aimed to evaluate the effect of core shade and core and veneering thickness on color parameters and translucency of polyether ether ketone (PEEK). Sixty PEEK discs (0.5 and 1 mm in thickness) with white and dentine shades were veneered with A2 shade indirect composite resin with 0.5, 1 and 1.5 mm thickness (n=5). Cores without the veneering material served as controls for translucency evaluation. Color parameters were measured by a spectroradiometer. Color difference (DeltaE00) and translucency parameters (TP) were computed. Data were analyzed using one-way ANOVA and Tukey's test (for veneering thickness) and independent t-test (for core shade and thickness) via SPSS 20.0 (p?0.05). Regarding the veneering thickness, white cores of 0.5 mm thickness showed significant differences in all color parameters. In white cores of 1 mm thickness and dentine cores of 0.5 and 1 mm thickness, there were statistically significant differences only in L*, a* and h*. The mean TP was significantly higher in all white cores of 1 mm thickness than dentine cores of 1 mm. Considering DeltaE00=3.7 as clinically unacceptable, only three groups had higher mean DeltaE00 values. Core shade, core thickness, and the veneering thickness affected the color and translucency of PEEK restorations. PMID- 29182214 TI - An Investigation into the Trueness and Precision of Copy Denture Templates Produced by Rapid Prototyping and Conventional Means. AB - OBJECTIVE: To assess the trueness and precision of copy denture templates produced using traditional methods and 3D printing. MATERIAL AND METHODS: Six copies of a denture were made using: 1. Conventional technique with silicone putty in an impression tray (CT). 2. Conventional technique with no impression tray (CNT). 3. 3D scanning and printing (3D). Scan trueness and precision was investigated by scanning a denture six times and comparing five scans to the sixth. Then the scans of the six CT, CNT and 3D dentures were compared by aligning, in turn, the copies of each denture to the scanned original. Outcome measures were the mean surface-to-surface distance, standard deviation of that distance and the maximum distance. Student's unpaired t-tests with Bonferroni correction were used to analyse the results. RESULTS: The repeated scans of the original denture showed a scan trueness of 0.013mm (SD 0.002) and precision of 0.013mm (SD 0.002). Trueness: CT templates, 0.168mm (0.047), CNT templates 0.195mm (0.034) and 3D 0.103mm (0.021). Precision: CT templates 0.158mm (0.037), CNT 0.233mm (0.073), 3D 0.090mm (0.017). For each outcome measure the 3D templates demonstrated an improvement which was statistically significant (p?0.05). CONCLUSIONS: 3D printed copy denture templates reproduced the original with greater trueness and precision than conventional techniques. PMID- 29182215 TI - A Measurement Protocol for the Marginal and Internal Fit of All-Ceramic Crowns. AB - AIMS: To evaluate in vitro the influence of firing on marginal and internal fit of all-ceramic milled and pressed lithium-disilicate crowns. MATERIALS AND METHODS: One Standardized model with 1.6mm occlusal and 1.4mm axial reduction was used to fabricate 64 crowns. Using a factorial design, eight groups of lithium disilicate ceramics (n=8) using P=press, C=CAD/CAM, M=monolithic, O=coping, V=veneered, R=as produced: PMR, PMG, POR, PVG, CMR, CMG, COR, CVG. Crowns were produced and cemented on stone dies, then embedded in clear epoxy resin and sectioned into two plains. With a digital microscope, the distance between die and crowns was measured at the occlusal and axial walls. The horizontal/vertical fit at the finishing line of each section were measured as well. RESULTS: For the marginal fit, the analysis shows that the influence of material and design was significant on horizontal and vertical margins, and the influence of finish was significant with horizontal but not vertical margins (p=0.09). For the internal fit, the analysis showed that the axial gap was significantly influenced by material and finish but not by design (p=0.44). CONCLUSIONS: With a few exceptions, horizontal and vertical marginal discrepancies were below 100 MUm. Additional firing increased the discrepancies. PMID- 29182216 TI - Adhesion and Early Colonization of S. Mutans on Lithium Disilicate Reinforced Glass-Ceramics, Monolithic Zirconia and Dual Cure Resin Cement. AB - OBJECTIVE: Monolithic zirconia and glass ceramics are increasingly used in implant crowns. Limited data is available on bacterial adhesion and early biofilm formation on these materials. METHODS: Four different materials were investigated: (1) Lithium disilicate glass-ceramics (LDS), (2) Fully stabilized zirconia (FSZ), (3) Partially stabilized zirconia (PSZ), and (4) Dual curing cement (DCC). The materials' surfaces were characterized with spinning disc confocal microscopy and by water contact angle and surface free energy (SFE) measurements. For the adhesion tests the materials were rolled in suspensions of Streptococcus mutans. Early biofilm formation was studied on the materials and allowing the biofilms to form for 24 h. S. mutans cell counts were determined by plate culturing. ANOVA and post-hoc Tukey's tests (p?0.05) were used for statistical evaluation. RESULTS: The LDS surfaces were clearly hydrophilic with the highest SFE value (p?0.001). For S. mutans adhesion, the ranking of the materials from lowest to highest was: LDS = FSZ ? DCC ? PSZ (p?0.05). No significant differences among the materials were noticed in biofilm formation. CONCLUSIONS: LDS has lower S.mutans adhesion than other materials examined in this study, but the difference was not reflected in early biofilm formation. PMID- 29182217 TI - The Effect of Surface Preparation of Acrylic Teeth. AB - PURPOSE: To investigate whether the chemical bond between acrylic teeth and heat polymerized PMMA can be altered by chemical and/or mechanical treatment. MATERIALS AND METHODS: One hundred fifty acrylic teeth were divided in groups of 10. Their ridge lap surface underwent mechanical and/or chemical treatments: 1) no treatment, 2) air-abrasion with Al2O3 particles, 3) acid etching with phosphoric acid, 4) application of composite resin bonding agent, 5) application of MMA and ethylmethylketone bonding agent, 6) PMMA monomer application. The teeth were then placed in heat polymerized acrylic resin. Each specimen was compressed with a universal testing machine. Descriptive statistics, one-way ANOVA (alpha=0.05) and Tukey's HSD test were used. A scanning electron microscope (SEM) was also used to study the fracture areas. RESULTS: Statistically significant differences (p?0.001) in the bond strength were found. The strongest bond (239.41 N), was noted in the group treated with sandblasting followed by PMMA monomer application. CONCLUSIONS: Mechanical and/or chemical preparations affect significantly the bond strength between the acrylic resin denture teeth and the PMMA denture base. Air abrasion was the most effective treatment, either alone or combined with other treatments. PMID- 29182218 TI - Hepatitis A in Poland in 2015 AB - AIM: The aim of this article is to assess the epidemiological situation of Hepatitis A in Poland in 2015 with theregard to the recent years. MATERIALS AND METHODS: The assessment was conducted based on the results of the analysis of data fromthe bulletins "Infectious diseases and poisonings in Poland in 2015" and "Vaccinations in Poland in 2015", as wellas information from the individual cases questionnaires and reports of epidemiological investigations in outbreaksof hepatitis A, submitted by the sanitary-epidemiological stations to the Department of Epidemiology in NIPH-NIH. RESULTS: In 2015 in Poland there were 49 cases of hepatitis A registered. Incidence per 100 000 inhabitantswas 0,13, and in different voivodeships varied from 0,03 (in Dolnoslaskie, Malopolskie voivodeship) to 0,36 (inMalopolskie voivodeship). The incidence among male and female was similar - 0.11 i 0.15/100 000 respectively. CONCLUSIONS: In 2015 despite the decrease in the number of cases (comparing it to the previous year) no significantchange in epidemiological situation of hepatitis A was observed. In the course of routine surveillance no informationare gathered concerning the risk groups affiliation of persons being vaccinated. This information would facilitatethe creation of recommendations for the vaccination against hepatitis A policy. In regard of the increase of populationsusceptible to infection the maintenance of high level routine surveillance in Poland gains particular importance. PMID- 29182219 TI - Hepatitis B in Poland in 2015 AB - OBJECTIVE: Assessment of the epidemiological situation of hepatitis B in Poland in 2015 in relation toprevious years. MATERIAL AND METHODS: Evaluation of the epidemiological situation carried out based on analysisof data from individual reports on acute hepatitis B cases registered by the sanitary-epidemiological stations,aggregate data published in annual bulletins "Infectious diseases and poisonings in Poland" and data from annualbulletin "Vaccinations in Poland". RESULTS: In total, 3 518 cases of hepatitis B were registered in 2015, including 24 cases of HBV/ HCVco-infections. Acute cases accounted for 1.5% of all recorded cases, with a sustained downward trend inincidence - 0.14 per 100,000. Incidence of acute hepatitis B was lower by 22% compared to the previous year.In group of children up to 14 years old, covered by universal vaccinations of neonates, 1 acute case was reportedin a 4-month-old child. Most of acute hepatitis B infections (58%) were probably acquired during medicalprocedures performed in health care settings.The number of chronic and unknown (in terms of stage) cases registered increased in comparison with theprevious year, the incidence was 9.0 per 100,000 population and was higher by 29% than in 2014. Chronicinfections and UNK occurred 1.3-fold more frequently in men than in women and 1.5-fold more frequentlyamong urban dwellers than in rural population.In 2015, three people died due to acute hepatitis B, and 57 people due to chronic. CONCLUSIONS: The changes implemented in surveillance in 2014 allow for gradual reducing of territorialdisparities and for assessment of the actual number of newly detected infections. Maintenance of a low incidenceof acute hepatitis B provides the premise for sustain existing preventive measures, especially universal vaccinationof newborns and recommendation to vaccinate of all persons previously unvaccinated. PMID- 29182220 TI - Hepatitis C in Poland in 2015 AB - INTRODUCTION: On account of the asymptomatic course, no possibility to prevent by vaccination andthe serious consequences of long-term infection (liver cirrhosis, hepatocellular carcinoma), hepatitis C (HCVinfection) is a serious public health problem. OBJECTIVE: This article aims are evaluating the epidemiological situation of HCV infections in Poland in2015 in reference to the data from previous years. MATERIAL AND METHODS: Analysis of epidemiological situation of hepatitis C in Poland was carried outon a basis of aggregated data from routine surveillance system published in annual bulletin "Infectious Diseasesand Poisonings in Poland". Data on hepatitis C mortality from the Demographic Surveys and Labour MarketDepartment of the Central Statistical Office were also included. In 2015, mandatory reporting included: 1) HCVinfections diagnosed by physicians and 2) positive laboratory test results for HCV. RESULTS: In 2015, a total of 4,285 cases were reported (diagnosis rate 11.14 per 100,000). The diagnosis rateincreased by 21% compared to 2014 (2014: 3 551 cases, 9.23 per 100,000) and doubled with respect to the medianvalue in 2009-2013 (2,189 cases, 5.68 per 100,000). For the first time the diagnosis rates in men and women werecomparable (11.10 per 100,000 vs. 11.19 per 100,000). The percentage of people hospitalized due to HCV infection atHCV diagnosis decreased (in 2015 - 39.0%, in 2014 - 48.4%). In 2015, 239 deaths due to hepatitis C were registered. CONCLUSIONS: The increased diagnosis rate of hepatitis C in 2015 may be a consequence of improved reporting,legislative changes (introduction of mandatory reporting of positive laboratory results) as well as enhanced publicityand other HCV control activities, including increased availability of HCV laboratory screening. PMID- 29182221 TI - Tetanus in Poland in 2015 AB - : The number of tetanus in the 21st century shows a slight declining trend, but each year there is reported fatalcases of this disease. THE PURPOSE of the STUDY: The purpose of the study is to provide data on epidemiological surveillanceof the tetanus in 2015. MATERIAL AND METHODS: The study is based on the individual forms of tetanus cases submitted to theNIZP-PZH Epidemiology Department and the data of the bulletin "Infectious Diseases and Poisoning in Polandin 2015. RESULTS: In 2015, 12 cases of tetanus were reported. Six men and six women became ill. 4 people died after69 years of age. SUMMARY AND CONCLUSIONS: Tetanus is an infectious disease acquired in the environment andassociated with wound contamination. Infections can be prevented by vaccination. Particularly threat to life andhealth carries disease in the late age. PMID- 29182222 TI - HIV and AIDS in Poland in 2015 AB - AIM: AIM. The aim was to describe the epidemiological situation of newly diagnosed HIV infections and AIDS casesin Poland in 2015 in comparison to the previous years. MATERIALS AND METHODS: Descriptive analysis of newly detected HIV cases and AIDS cases wasperformed based on routine notifications by clinicians and laboratories. Data on the number of HIV tests fromannual survey among laboratories were also used. RESULTS: In 2015 there were 1,281 HIV cases newly diagnosed in Poland (diagnosis rate 3.33 per 100,000 population),including 23 among non-Polish citizens. The rate of new cases rose by 15% compared to the previous year as well as tothe median in 2009 - 2013. The total number of AIDS cases was 128 (incidence 0.38 per 100,000) and 41 AIDS patientsdied (0.11 per 100,000). HIV infection was mainly detected among people aged from 20 to 39 years (71.3%) and amongmales (84.8%). Among men, 67.6% of newly diagnosed infections with known transmission category were acquired bymen who have sex with men (MSM). The percentage of infected men in this group, compared to 2014, increased from64.5% to 67.6%. The percentage of newly diagnosed persons infected by heterosexual contact decreased from 24.1% to21.1% (persons with known transmission category). The percentage of people with HIV diagnosed at the same time asAIDS diagnosed decreased in comparison with 2014 (from 9.2% to 6.9% of newly detected HIV infections). CONCLUSIONS: HIV epidemic continues to develop among MSM in Poland. However, assessment ofepidemiological situation is limited by the missing data on the probable transmission route in a large percentageof reported newly detected HIV infection. PMID- 29182223 TI - Tuberculosis in Poland in 2015 AB - AIM OF THE STUDY: To evaluate the main features of TB epidemiology in 2015 in Poland and to compare withthe data on the same phenomena in the EU/EEA countries. METHODS: Analysis of case - based data on TB patients from National TB Register, data on anti-TB drugsusceptibility testing results in cases notified in 2015, data from National Institute of Public Health- National Instituteof Hygiene on cases of tuberculosis as AIDS-defining disease, data from Central Statistical Office on deaths fromtuberculosis based on death certificates, data from ECDC report " European Centre for Disease Prevention andControl/WHO Regional Office for Europe. Tuberculosis surveillance and monitoring in Europe 2017. Stockholm:European Centre for Disease Prevention and Control, 2017". RESULTS: 6430 TB cases were reported in Poland in 2015. The incidence rate was 16.7 cases per 100 000, withlarge variability between voivodeships from 8.3 to 26.5 per 100 000. The mean annual decrease of TB incidencein 2011- 2015 was 5.5%. 5757 cases were new, never treated i.e. 15.0 per 100 000. 673 cases i.e. 1.8 per 100 000 10.5% of all registered subjects were previously treated.The number of all notified pulmonary tuberculosis cases in 2015 was 6078 i.e. 15.8 per 100 000. Pulmonary casesrepresented 94.5% of all TB cases. The number of pulmonary TB cases with bacteriological confirmation was 4472i.e. 11,6 per 100 000. In 2015, only 352 extrapulmonary TB cases were reported. Children accounted for 1.3% ofall TB cases in Poland; 81 pediatric cases were notified. The incidence of tuberculosis has been growing along withthe age group from 1.4 per 100 000 among children to 28.1 per 100 000 among patients aged 45 to 64 years. In theage group 65 years old and older the incidence was 26.9 per 100 000.The incidence among men i.e. 24.0 per 100 000 was >2 times higher than among women i.e. 9.9 per 100 000. Thebiggest difference in the TB incidence between the two sex groups occurred in persons aged 50 to 54 years - 45.6vs. 12.4 and in subjects aged 55 to 59 years (53.3 vs. 12.8). The TB incidence in rural population was lower than inurban, respectively 16.5 per 100 000 and 16.9 per 100 000.The number of all registered culture positive TB cases, including cases previously treated, was 4630. Cultureconfirmedcases constituted 72.0% of all TB cases; culture-confirmed pulmonary TB - 73.6% of all pulmonary TBcases. The number of smear positive/culture positive pulmonary TB cases reported in 2015 was 2714 i.e. 7.1 per100 000 respectively what constituted 44.7% of all pulmonary TB cases.TB was initial AIDS indicative disease in 20 persons. In Poland in 2015 there were 35 cases with MDR-TB (amongthem 5 foreigners) and 95 patients with resistance solely to isoniazid, constituting respectively 0.8% and 2.3% ofcases with known DST results (DSTs were done in 91.6% of all culture-confirmed TB cases). There were 52 casesof tuberculosis registered among foreigners in 2015.There were 526 deaths due to tuberculosis reported in 2014 - 1.4 per 100 000; 504 people died from pulmonaryand 22 from extrapulmonary tuberculosis. Mortality among males - 2.2 per 100 000 - was 3.6 x higher than amongfemales - 0.6. The highest mortality rate was in subjects 65 years old and older - 3.8 per 100 000. There were nodeaths from tuberculosis in children. TB was cause of death in one adolescent. TB mortality in 2014 constituted0.14% of total mortality in Poland and 27.4% of mortality from infectious diseases. CONCLUSIONS: In Poland in 2015 the incidence of tuberculosis was lower than in the past but higher than theaverage in the EU/EEA countries. The highest incidence rates occurred in older age groups. The incidence in menwas more than 2 times higher than in women. In Poland, tuberculosis in children, tuberculosis in persons infectedwith HIV and MDR-TB are less common than in the EU/EEA countries.

AB - Solution-based processing of two-dimensional (2D) materials provides the possibility of allowing these materials to be incorporated into large-area thin films, which can translate the interesting fundamental properties of 2D materials into available devices. Here, we report for the first time a novel chemical welding method to achieve high-performance flexible n-type thermoelectric films using 2D semimetallic TiS2 nanosheets. We employ chemically exfoliated TiS2 nanosheets bridged with multivalent cationic metal Al3+ to cross-link the nearby sheets during the film deposition process. We find that such a treatment can greatly enhance the stability of the film and can improve the power factor by simultaneously increasing the Seebeck coefficient and electrical conductivity. The resulting TiS2 nanosheet-based flexible film shows a room temperature power factor of ~216.7 MUW m-1 K-2, which is among the highest chemically exfoliated 2D transition-metal dichalcogenide nanosheet-based films and comparable to the best flexible n-type thermoelectric films, to our knowledge, indicating its potential applications in wearable electronics.

AB - Li-ion batteries are a green energy storage technology with advantages of high energy density, long lifetime, and sustainability, but they cannot generate electric energy by themselves. As a novel energy-harvesting technology, triboelectric nanogenerators (TENGs) are a promising power source for supplying electronic devices, however it is difficult to directly use their high output voltage and low output current. Here, we designed a Ag nanoparticle-based TENG for scavenging wind energy. After including a transformer and a power management circuit into the system, constant output voltages such as 3.6 V and a pulsed current of about 100 mA can be obtained, which can be used to directly light up a light-emitting diode. Furthermore, the produced electric energy can be effectively stored in a WO3/LiMn2O4 electrode based Li-ion battery. Our present work provides a new approach to effectively scavenge wind energy and store the obtained electric energy, which is significant for exploring self-charging power units.

AB - In recent years, highly conductive, printable electrodes have received tremendous attention in various research fields as the most important constituent components for large-area, low-cost electronics. In terms of an indispensable sintering process for generating electrodes from printable metallic nanomaterials, a flashlight-based sintering technique has been regarded as a viable approach for continuous roll-to-roll processes. In this paper, we report cost-effective, printable Cu electrodes that can be applied to vulnerable polyethylene terephthalate (PET) substrates, by incorporating a heretofore-unrecognized ultrathin plasmonic thermal/optical barrier, which is composed of a 30 nm thick Ag nanoparticle (NP) layer. The different plasmonic behaviors during a flashlight sintering process are investigated for both Ag and Cu NPs, based on a combined interpretation of the experimental results and theoretical calculations. It is demonstrated that by a continuous printing process and a continuous flashlight sintering process, the Cu electrodes are formed successfully on large PET substrates, with a sheet resistance of 0.24 Omega/sq and a resistivity of 22.6 MUOmega.cm. PMID- 29182242 TI - Synergistic Effect of Partially Fluorinated Ether and Fluoroethylene Carbonate for High-Voltage Lithium-Ion Batteries with Rapid Chargeability and Dischargeability. AB - The roles of a partially fluorinated ether (PFE) based on a mixture of 1,1,1,2,2,3,3,4,4-nonafluoro-4-methoxybutane and 2-(difluoro(methoxy)methyl) 1,1,1,2,3,3,3-heptafluoropropane on the oxidative durability of an electrolyte under high-voltage conditions, the rate capability of the graphite and 5 V-class LiNi0.4Mn1.6O4 (LNMO) electrodes, and the cycling performance of graphite/LNMO full cells are examined. Our findings indicate that the use of PFE as a cosolvent in the electrolyte yields thermally stable electrolytes with self-extinguishing ability. Electrochemical tests confirm that the PFE combined with fluoroethylene carbonate (FEC) effectively alleviates the oxidative decomposition of the electrolyte at the high-voltage LNMO cathode and enables reversible electrochemical reactions of the graphite anodes and LNMO cathodes at high rates. Moreover, the combination of PFE, which mitigates electrolyte decomposition at high voltages, and FEC, which stabilizes the anode-electrolyte interface, enables the reversible cycling of high-voltage full cells (graphite/LNMO) with a capacity retention of 70.3% and a high Coulombic efficiency of 99.7% after 100 cycles at 1C rate at 30 degrees C. PMID- 29182243 TI - Targeting the Thioredoxin Reductase-Thioredoxin System from Staphylococcus aureus by Silver Ions. AB - The thioredoxin system, which is composed of NADPH, thioredoxin reductase (TrxR), and thioredoxin (Trx), is one of the major disulfide reductase systems used by bacteria against oxidative stress. In particular, this reductase system is crucial for the survival of the pathogenic bacterium Staphylococcus aureus, which lacks a natural glutathione/glutaredoxin (Grx) system. Although silver ions and silver-containing materials have been used as antibacterial agents for centuries, the antibacterial mechanism of silver is not well-understood. Herein, we demonstrate that silver ions bind to the active sites of S. aureus TrxR and Trx with dissociation constants of 1.4 +/- 0.1 MUM and 15.0 +/- 5.0 MUM and stoichiometries of 1 and 2 Ag+ ions per protein, respectively. Importantly, silver ion binding leads to oligomerization and functional disruption of TrxR as well as Trx. Silver also depleted intracellular thiol levels in S. aureus, disrupting bacterial thiol-redox homeostasis. Our study provides new insights into the antibacterial mechanism of silver ions. Moreover, the Trx and TrxR system might serve as a feasible target for the design of antibacterial drugs. PMID- 29182245 TI - Molecular "Flower" as the High-Mobility Hole-Transport Material for Perovskite Solar Cells. AB - To develop novel hole-transport materials (HTMs) with less synthetic steps is still a great challenge. Here, a small molecule hexakis[4-(N,N-di-p methoxyphenylamino)phenyl]benzene (F-1) was successfully synthesized by a relatively simple scenario. F-1 exhibits a deep highest occupied molecular orbital energy level of -5.31 eV. Notably, F-1 also features 2 times higher hole mobility of 4.98 * 10-4 cm2 V-1 s-1 than that of the mostly used 2,2',7,7' tetrakis(N,N-bis(4-methoxyphenyl)amino)-9,9'-spirobifluorene (spiro-OMeTAD). Consequently, F-1-based perovskite solar cells (PSCs) show markedly improved performance compared with spiro-OMeTAD-based ones. These results indicate such a material can be a promising HTM candidate to boost the overall performance of the PSC. PMID- 29182244 TI - Allosteric Modulation of Grb2 Recruitment to the Intrinsically Disordered Scaffold Protein, LAT, by Remote Site Phosphorylation. AB - Tyrosine phosphorylation of membrane receptors and scaffold proteins followed by recruitment of SH2 domain-containing adaptor proteins constitutes a central mechanism of intracellular signal transduction. During early T-cell receptor (TCR) activation, phosphorylation of linker for activation of T cells (LAT) leading to recruitment of adaptor proteins, including Grb2, is one prototypical example. LAT contains multiple modifiable sites, and this multivalency may provide additional layers of regulation, although this is not well understood. Here, we quantitatively analyze the effects of multivalent phosphorylation of LAT by reconstituting the initial reactions of the TCR signaling pathway on supported membranes. Results from a series of LAT constructs with combinatorial mutations of tyrosine residues reveal a previously unidentified allosteric mechanism in which the binding affinity of LAT:Grb2 depends on the phosphorylation at remote tyrosine sites. Additionally, we find that LAT:Grb2 binding affinity is altered by membrane localization. This allostery mainly regulates the kinetic on-rate, not off-rate, of LAT:Grb2 interactions. LAT is an intrinsically disordered protein, and these data suggest that phosphorylation changes the overall ensemble of configurations to modulate the accessibility of other phosphorylated sites to Grb2. Using Grb2 as a phosphorylation reporter, we further monitored LAT phosphorylation by TCR zeta chain-recruited ZAP-70, which suggests a weakly processive catalysis on membranes. Taken together, these results suggest that signal transmission through LAT is strongly gated and requires multiple phosphorylation events before efficient signal transmission is achieved.

AB - Nanochannel/nanopre based analysis methods have attracted increasing interest in recent years due to their exquisite ability to reveal changes in molecular volume. In this work, a highly asymmetric nanochannel-ionchannel hybrid coupled with an electrochemical technique was developed for copper ion (Cu2+) detection. Polyglutamic acid (PGA) was modified in a nanochannel array of porous anodic alumina (PAA). When different concentrations of Cu2+ were introduced into the nanochannel-ionchannel hybrid in a neutral environment, a Cu2+-PGA chelation reaction occurs, resulting in varied current-potential (I-V) properties of the nanochannel-ionchannel hybrid. When PAA was immersed in a low pH solution, the Cu2+-PGA complex dissociated. On the basis of the change in ionic current, a label-free assay for Cu2+ was achieved along with the ability to regenerate and reuse the constructed platform. Because of the unique mass transfer property of the nanochannel-ionchannel hybrid combined with the highly amplified ionic current magnitude of the nanochannel array, significantly increased assay sensitivity was achieved, as expected. To evaluate the applicability of the present methodology for detecting Cu2+ in a real sample, the Cu2+ content in real blood samples was analyzed. The results demonstrate that the present method shows excellent selectivity with high sensitivity toward Cu2+ detection in real blood samples. PMID- 29182267 TI - An Improved Whole-Cell Biosensor for the Discovery of Lignin-Transforming Enzymes in Functional Metagenomic Screens. AB - The discovery and utilization of biocatalysts that selectively valorize lignocellulose is critical to the profitability of next-generation biorefineries. Here, we report the development of a refactored, whole-cell, GFP-based biosensor for high-throughput identification of biocatalysts that transform lignin into specialty chemicals from environmental DNA of uncultivable archaea and bacteria. The biosensor comprises the transcriptional regulator and promoter of the emrRAB operon of E. coli, and the configuration of the biosensor was tuned with the aid of mathematical model. The biosensor sensitively and selectively detects vanillin and syringaldehyde, and responds linearly over a wide detection range. We employed the biosensor to screen 42 520 fosmid clones comprising environmental DNA isolated from two coal beds and successfully identified 147 clones that transform hardwood kraft lignin to vanillin and syringaldehyde. PMID- 29182268 TI - Core Richness of N-Glycans of Caenorhabditis elegans: A Case Study on Chemical and Enzymatic Release. AB - Despite years of research, the glycome of the model nematode Caenorhabditis elegans is still not fully understood. Certainly, data over the years have indicated that this organism synthesizes unusual N-glycans with a range of galactose and fucose modifications on the Man2-3GlcNAc2 core region. Previously, up to four fucose residues were detected on its N-glycans, despite these lacking the fucosylated antennae typical of many other eukaryotes; some of these fucose residues are capped with hexose residues as shown by the studies of us and others. There have, though, been contrasting reports regarding the maximal number of fucose substitutions in C. elegans, which in part may be due to different methodological approaches, including use of either peptide:N-glycosidases F and A (PNGase F and A) or anhydrous hydrazine to cleave the N-glycans from glycopeptides. Here we compare the use of hydrazine with that of a new enzyme (rice PNGase Ar) and show that both enable release of glycans with more sugar residues on the proximal GlcNAc than previously resolved. By use of exoglycosidase sequencing, in conjunction with high-performance liquid chromatography (HPLC) and matrix-assisted laser desorption ionization time-of flight tandem mass spectrometry (MALDI-TOF MS/MS), we now reveal that actually up to five fucose residues modify the core region of C. elegans N-glycans and that the alpha1,3-fucose on the reducing terminus can be substituted by an alpha linked galactose. Thus, traditional PNGase F and A release may be insufficient for release of the more highly core-modified N-glycans, especially those occurring in C. elegans, but novel enzymes can compete against chemical methods in terms of safety, ease of cleanup, and quality of resulting glycomic data. PMID- 29182269 TI - Multistability at Room Temperature in a Bent-Shaped Spin-Crossover Complex Decorated with Long Alkyl Chains. AB - An iron(II) pyridyl-benzohydrazonate-based complex decorated with long alkyl chains is reported as a rare spin-crossover compound displaying a wide thermal hysteresis spanning room temperature. On heating, this compound exhibits a spin transition between a LS ground state and an ordered HS-LS phase with symmetry breaking from monoclinic P21/n into orthorhombic P21212 space groups. During cooling, the compound first transits into a magnetically distinguishable HS-LS phase with monoclinic P21 symmetry before returning into the LS phase. Interconversion between the two distinct HS-LS phases is the result of subtle structural changes in the alkyl chains and produces a second minor thermal hysteresis that superposes to the large one. This unprecedented result shows that the combination of a conventional cooperative spin transition and ligand-driven magnetic changes can promote magnetic tristability at room temperature. PMID- 29182270 TI - Advances in the Chemical Biology of Desferrioxamine B. AB - Desferrioxamine B (DFOB) was discovered in the late 1950s as a hydroxamic acid metabolite of the soil bacterium Streptomyces pilosus. The exquisite affinity of DFOB for Fe(III) identified its potential for removing excess iron from patients with transfusion-dependent hemoglobin disorders. Many studies have used semisynthetic chemistry to produce DFOB adducts with new properties and broad ranging functions. More recent approaches in chemical biology have revealed some nuances of DFOB biosynthesis and discovered new DFOB-derived drugs and radiometal imaging agents. The current and potential applications of DFOB continue to inspire a rich body of chemical biology research focused on this bacterial metabolite. PMID- 29182271 TI - Regio- and Chemoselective Hydrogenation of Dienes to Monoenes Governed by a Well Structured Bimetallic Surface. AB - Unprecedented surface chemistry, governed by specific atomic arrangements and the steric effect of ordered alloys, is reported. Rh-based ordered alloys supported on SiO2 (RhxMy/SiO2, M = Bi, Cu, Fe, Ga, In, Pb, Sn, and Zn) were prepared and tested as catalysts for selective hydrogenation of trans-1,4-hexadiene to trans-2 hexene. RhBi/SiO2 exhibited excellent regioselectivity for the terminal C?C bond and chemoselective hydrogenation to the monoene, not to the overhydrogenated alkane, resulting in a high trans-2-hexene yield. Various asymmetric dienes, including terpenoids, were converted into the corresponding inner monoenes in high yields. This is the first example of a regio- and chemoselective hydrogenation of dienes using heterogeneous catalysts. Kinetic studies and density functional theory calculations revealed the origin of the high selectivity: (1) one-dimensionally aligned Rh arrays geometrically limit hydrogen diffusion and attack to alkenyl carbons from one direction and (2) adsorption of the inner C?C moiety to Rh is inhibited by steric repulsion from the large Bi atoms. The combination of these effects preferentially hydrogenates the terminal C?C bond and prevents overhydrogenation to the alkane.

AB - A two-photon fluorescent probe based on a ruthenium(II) vinyl complex is capable of selectively detecting carbon monoxide in cells and ex vivo using mice with a subcutaneous air pouch as a model for inflammation. This probe combines highly selective and sensitive ex vivo detection of endogenous CO in a realistic model with facile, inexpensive synthesis, and displays many advantages over the widely used palladium-based systems. PMID- 29182273 TI - Structural Investigation of a Dimeric Variant of Pyruvate Kinase Muscle Isoform 2. AB - Pyruvate kinase muscle isoform 2 (PKM2) catalyzes the terminal step in glycolysis, transferring a phosphoryl group from phosphoenolpyruvate to ADP, to produce pyruvate and ATP. PKM2 activity is allosterically regulated by fructose 1,6-bisphosphate (FBP), an upstream glycolytic intermediate. FBP stabilizes the tetrameric form of the enzyme. In its absence, the PKM2 tetramers dissociate, yielding a dimer-monomer mixture having lower enzymatic activity. The S437Y variant of PKM2 is incapable of binding FBP. Consistent with that defect, we find that S437Y exists in a monomer-dimer equilibrium in solution, with a Kd of ~20 MUM. Interestingly, however, the protein crystallizes as a tetramer, providing insight into the structural basis for impaired FBP binding of S437Y. PMID- 29182274 TI - Organic Photosensitizers Incorporating Rigid Benzo[1,2-b:6,5-b']dithiophene Segment for High-Performance Dye-Sensitized Solar Cells. AB - Benzo[1,2-b:6,5-b']dithiophene (BDT) entity with rigid skeleton is introduced into the conjugated spacer of organic dyes, with triphenylamine as the electron donor and 2-cyanoacrylic acid as the acceptor, have been prepared for dye sensitized solar cells. Inserting an aromatic entity between BDT and the anchor extends the absorption wavelength of the dyes and improves the dark current suppression efficiency, and consequently leads to better cell performance. Addition of chenodeoxycholic acid coadsorbent alleviates dye aggregation and results in better cell efficiency. The dye inserted with 4H-cyclopenta[2,1-b:3,4 b']dithiophene entity achieves the best efficiency (9.11%) when I-/I3- was used as the electrolyte. When Co(phen)32+/3+ was used as the electrolyte, the efficiency further boosts to 9.88%.

AB - High thermoelectric performance of n-type PbTe is urgently needed to match its p type counterpart. Here, we show a peak ZT ~ 1.5 at 723 K and a record high average ZT > 1.0 at 300-873 K realized in n-type PbTe by synergistically suppressing lattice thermal conductivity and enhancing carrier mobility by introducing Cu2Te inclusions. Cu performs several outstanding roles: Cu atoms fill the Pb vacancies and improve carrier mobility, contributing to an unexpectedly high power factor of ~37 MUW cm-1 K-2 at 423 K; Cu atoms filling Pb vacancies and Cu interstitials both induce local disorder and, together with nano and microscale Cu-rich precipitates and their related strain fields, lead to a very low lattice thermal conductivity of ~0.38 Wm-1 K-1 in PbTe-5.5%Cu2Te, approaching the theoretical minimum value of ~0.36 Wm-1 K-1. This work provides an effective strategy to enhance thermoelectric performance by simultaneously improving electrical and thermal transport properties. PMID- 29182276 TI - Identifying Structure in Short DNA Scaffolds Using Solid-State Nanopores. AB - The identification of molecular tags along nucleic acid sequences has many potential applications in bionanotechnology, disease biomarker detection, and DNA sequencing. An attractive approach to this end is the use of solid-state nanopores, which can electrically detect molecular substructure and can be integrated into portable lab-on-a-chip sensors. We present here a DNA origami based approach of molecular assembly in which solid-state nanopores are capable of differentiating 165 bp scaffolds containing zero, one, and two dsDNA protrusions. This highly scalable technique requires minimal sample preparation and is customizable for a wide range of targets and applications. As a proof-of concept, an aptamer-based DNA displacement reaction is performed in which a dsDNA protrusion is formed along a 255 bp scaffold in the presence of ATP. While ATP is too small to be directly sensed using conventional nanopore methods, our approach allows us to detect ATP by identifying molecular substructure along the DNA scaffold. PMID- 29182277 TI - Overall Content of Salicylic Acid and Salicylates in Food Available on the European Market. AB - The study aimed to determine the salicylates content in 112 products available on the European market. Quantitative determination of free and conjugated forms of salicylic acid in food was performed using reversed-phase high-performance liquid chromatography with fluorescence detection. The salicylates contents ranged from 0 to 1675.79 (MUg/100 g). The results of this study confirm the presence of salicylates in food products, as well as a broad content diversity of these compounds depending on the species, variety, and method of processing the food items. The results can be very helpful for nutritionists and dieticians in planning low-salicylates or high-salicylates diets. PMID- 29182278 TI - Understanding How Sterols Regulate Membrane Remodeling in Supported Lipid Bilayers. AB - The addition of single-chain lipid amphiphiles such as antimicrobial fatty acids and monoglycerides to confined, two-dimensional phospholipid bilayers can trigger the formation of three-dimensional membrane morphologies as a passive means to regulate stress. To date, relevant experimental studies have been conducted using pure phospholipid compositions, and extending such insights to more complex, biologically relevant lipid compositions that include phospholipids and sterols is warranted because sterols are important biological mediators of membrane stress relaxation. Herein, using the quartz crystal microbalance-dissipation (QCM D) technique, we investigated membrane remodeling behaviors triggered by the addition of sodium dodecyl sulfate (SDS), lauric acid (LA), and glycerol monolaurate (GML) to supported lipid bilayers (SLBs) composed of phospholipid and cholesterol mixtures. The SLB platforms were prepared by the solvent-assisted lipid bilayer method in order to form cholesterol-rich SLBs with tunable cholesterol fractions (0-52 mol %). The addition of SDS or LA to fabricated SLBs induced tubule formation, and the extent of membrane remodeling was greater in SLBs with higher cholesterol fractions. In marked contrast, GML addition led to bud formation, and the extent of membrane remodeling was lower in SLBs with higher cholesterol fractions. To explain these empirical observations, we discuss how cholesterol influences the elastic (stiffness) and viscous (stress relaxation) properties of phospholipid/cholesterol lipid bilayers as well as how the membrane translocation properties of single-chain lipid amphiphiles affect the corresponding membrane morphological responses. Collectively, our findings demonstrate that single-chain lipid amphiphiles induce highly specific membrane morphological responses across both simplified and complex model membranes, and cholesterol can promote or inhibit membrane remodeling by a variety of molecular mechanisms.

AB - We recently developed the polarizable charge equilibration (PQEq) model to predict accurate electrostatic interactions for molecules and solids and optimized parameters for H, C, N, O, F, Si, P, S, and Cl elements to fit polarization energies computed by quantum mechanics (QM). Here, we validate and optimize the PQEq parameters for other p-block elements including Ge, As, Se, Br, Sn, Sb, Te, I, Pb, Bi, Po, and At using 28 molecular structures containing these elements. For these elements, we now include molecules with higher oxidation states: III and V for the As column, IV and VI for the Se column, and I, III, and V for the Br column. We find that PQEq predicts polarization energies in excellent agreement with QM.

The resulting Pourbaix diagrams illustrate structural effects on their various redox potentials and on the p Ka values of the corresponding hydroxylamine and hydroxylammonium ions. Evidence is also given for the reversible formation of a hydroxylamine N-oxide when nitroxyls are oxidized in alkaline media. Structural effects on the thermodynamics of this reaction are assessed. PMID- 29182283 TI - Selective Single C(sp3)-F Bond Cleavage in Trifluoromethylarenes: Merging Visible Light Catalysis with Lewis Acid Activation. AB - The conversion of easily available trifluoromethylarenes into aryldifluoromethyl compounds, which are valuable motifs in the pharmaceutical chemistry, is highly atom- and step-economical. However, the single C(sp3)-F bond cleavage of ArCF3 is a great challenge because of the chemical inertness of the C(sp3)-F bond and the difficult selectivity control of monodefluorination. We report here the first example of single C(sp3)-F functionalization of trifluoromethylarenes via visible light catalysis merged with Lewis acid activation. The method allows good chemoselectivity control and shows good functional group tolerance. Mechanistic studies suggest an in situ-generated borenium cationic species as the key intermediate for C(sp3)-F bond cleavage in this reaction. PMID- 29182284 TI - Reconstructing the Surface of Gold Nanoclusters by Cadmium Doping. AB - Atomically precise metal nanoclusters with tailored surface structures are important for both fundamental studies and practical applications. The development of new methods for tailoring the surface structure in a controllable manner has long been sought. In this work, we report surface reconstruction induced by cadmium doping into the [Au23(SR)16]- (R = cyclohexyl) nanocluster, in which two neighboring surface Au atomic sites "coalesce" into one Cd atomic site and, accordingly, a new bimetal nanocluster, [Au19Cd2(SR)16]-, is produced. Interestingly, a Cd(S-Au-S)3 "paw-like" surface motif is observed for the first time in nanocluster structures. In such a motif, the Cd atom acts as a junction which connects three monomeric -S-Au-S- motifs. Density functional theory calculations are performed to understand the two unique Cd locations. Furthermore, we demonstrate different doping modes when the [Au23(SR)16]- nanocluster is doped with different metals (Cu, Ag), including (i) simple substitution and (ii) total structure transformation, as opposed to surface reconstruction for Cd doping. This work greatly expands doping chemistry for tailoring the structures of nanoclusters and is expected to open new avenues for designing nanoclusters with novel surface structures using different dopants.

Diverse 2-sulfonated indoles are generated by using 10 mol % of palladium(II) bromide as the catalyst at room temperature.

AB - A highly diastereoselective vinylogous nucleophilic 1,6-conjugate addition reaction of para-quinone methides with 3-propenyl-2-silyloxyindoles by a bismuth triflate catalyst has been developed.

AB - A novel approach to the diazatricyclic madangamine ABC ring system and the synthesis of an advanced, differentially protected intermediate for the synthesis of madangamine D is reported. Central to the success of this approach is the iodine(III)-mediated intramolecular oxamidation of an unsaturated O-methyl hydroxamate, a pi-N+-type cyclization which proceeds in high yield and with complete regioselectivity to generate the 2-azabicyclo[3.3.1]nonane (morphan) system encompassing rings A and C.

AB - A mild Ru/Ni dual catalytic desulfinative photoredox Csp2-Csp3 cross-coupling reaction of alkyl sulfinate salts with aryl halides has been developed. The optimized catalyst system, consisting of Ru(bpy)3Cl2, Ni(COD)2, and DBU, smoothly mediates the coupling of a diverse set of secondary and primary nonactivated alkyl sulfinate salts with a broad range of electron-deficient aryl bromides, electron-rich aryl iodides, and heteroaryl bromides under irradiation with blue light. The procedure is ideal for late-stage introduction of alkyl groups on pharmaceutical intermediates, and the Csp2-Csp3 cross-coupling reaction allowed the rapid synthesis of caseine kinase 1delta inhibitor analogues via a parallel medicinal chemistry effort. PMID- 29182292 TI - Ultrasensitive Ethene Detector Based on a Graphene-Copper(I) Hybrid Material. AB - Ethene is a highly diffusive and relatively unreactive gas that induces aging responses in plants in concentrations as low as parts per billion. Monitoring concentrations of ethene is critically important for transport and storage of food crops, necessitating the development of a new generation of ultrasensitive detectors. Here we show that by functionalizing graphene with copper complexes biologically relevant concentrations of ethene and of the spoilage marker ethanol can be detected. Importantly, in addition these sensors provide us with important insights into the interactions between molecules, a key concept in chemistry. Chemically induced dipole fluctuations in molecules as they undergo a chemical reaction are harvested in an elegant way through subtle field effects in graphene. By exploiting changes in the dipole moments of molecules that occur upon a chemical reaction we are able to track the reaction and provide mechanistic insight that was, until now, out of reach.

The method is applicable to a broad substrate range. PMID- 29182294 TI - Straightforward Integration Flow of a Silicon-Containing Block Copolymer for Line Space Patterning. AB - A promising alternative for the next-generation lithography is based on the directed self-assembly of block copolymers (BCPs) used as a bottom-up tool for the definition of nanometric features. Herein, a straightforward integration flow for line-space patterning is reported for a silicon BCP system, that is, poly(1,1 dimethylsilacyclobutane)-b-poly(styrene) (PDMSB-b-PS), able to define sub 15 nm features. Both in-plane cylindrical (L0 = 20.7 nm) and out-of-plane lamellar structures (L0 = 23.2 nm) formed through a rapid thermal annealing-10 min at 180 degrees C-were successfully integrated using graphoepitaxy to provide a long range ordering of the BCP structure without the use of underlayers or top coats. Subsequent deep transfer into the silicon substrate using the hardened oxidized PDMSB domains as a mask is demonstrated. Combining a rapid self-assembly behavior, straightforward integration, and an excellent etching contrast, PDMSB-b PS may become a material of choice for the next-generation lithography. PMID- 29182295 TI - Superlight, Mechanically Flexible, Thermally Superinsulating, and Antifrosting Anisotropic Nanocomposite Foam Based on Hierarchical Graphene Oxide Assembly. AB - Lightweight, high-performance, thermally insulating, and antifrosting porous materials are in increasing demand to improve energy efficiency in many fields, such as aerospace and wearable devices. However, traditional thermally insulating materials (porous ceramics, polymer-based sponges) could not simultaneously meet these demands. Here, we propose a hierarchical assembly strategy for producing nanocomposite foams with lightweight, mechanically flexible, superinsulating, and antifrosting properties. The nanocomposite foams consist of a highly anisotropic reduced graphene oxide/polyimide (abbreviated as rGO/PI) network and hollow graphene oxide microspheres. The hierarchical nanocomposite foams are ultralight (density of 9.2 mg.cm-3) and exhibit ultralow thermal conductivity of 9 mW.m-1.K 1, which is about a third that of traditional polymer-based insulating materials. Meanwhile, the nanocomposite foams show excellent icephobic performance. Our results show that hierarchical nanocomposite foams have promising applications in aerospace, wearable devices, refrigerators, and liquid nitrogen/oxygen transportation. PMID- 29182296 TI - Insight into the Origin of Capacity Fluctuation of Na2Ti6O13 Anode in Sodium Ion Batteries. AB - The capacity fluctuation phenomenon during cycling, which is closely related with solid electrolyte interphase and plays a key role for the design for advanced electrode, could be frequently observed in the titanium-based anode. However, the underlying reason for capacity fluctuation still remains unclear with rare related reports. Here, the origin of capacity fluctuation is verified with a long life Na2Ti6O13 anode. The reaction mechanism, structural evolution and reaction kinetics during the reported sodiation/desodiation processes were carefully investigated. The gradually enhanced diffusion controlled contribution resulted in the capacity increasing. And the capacity decay could be ascribed to the irreversible reaction of metallic titanium formation and the increasing potential polarization. It is worth noting that sodium ions seem to partially reduce NTO to metallic state, which is irreversible. The present study can provide more information for the design of advanced Na2Ti6O13 anode. PMID- 29182297 TI - Curious Case of Positive Current Collectors: Corrosion and Passivation at High Temperature. AB - In the evaluation of compatibility of different components of cell for high energy and extreme-conditions applications, the highly focused are positive and negative electrodes and their interaction with electrolyte. However, for high temperature application, the other components are also of significant influence and contribute toward the total health of battery. In present study, we have investigated the behavior of aluminum, the most common current collector for positive electrode materials for its electrochemical and temperature stability. For electrochemical stability, different electrolytes, organic and room temperature ionic liquids with varying Li salts (LiTFSI, LiFSI), are investigated. The combination of electrochemical and spectroscopic investigations reflects the varying mechanism of passivation at room and high temperature, as different compositions of decomposed complexes are found at the surface of metals. PMID- 29182298 TI - Controlling the Uptake and Regulating the Release of Nitric Oxide in Microporous Solids. AB - Representative compounds from three classes of microporous solids, namely, metal organic frameworks (MOFs), hybrid ultra-microporous materials (HUMs), and porous organic polymers (POPs), were investigated for their nitric oxide gas uptake and release behavior. Low-pressure sorption studies indicated strong chemisorption of NO on the free amine groups decorating the MOF UiO-66-NH2 when compared to its non-amine-functionalized parent. The HUMs demonstrated reversible physisorption within the low-pressure regime, but interestingly in one case there was evidence for chemisorption following pressurization with NO at 10 bar. Significant release of chemisorbed NO from the UiO-66-NH2 and one of the HUMs was triggered by addition of acid to the medium, a pH change from 7.4 to 5.4 being sufficient to trigger NO release. An imidazole-based POP exhibited chemisorption of NO at high pressure wherein the ring basicity facilitated both NO uptake and spontaneous release upon contact with the aqueous release medium. PMID- 29182299 TI - Switchable Conductive MOF-Nanocarbon Composite Coatings as Threshold Sensing Architectures. AB - Switchable metal-organic frameworks (MOFs) showing pronounced and stepwise volume changes as a response toward external stimuli such as partial pressure changes were integrated into electron conductive composites to generate novel threshold sensors with pronounced resistivity changes when approaching a critical partial pressure. Two "gate pressure" MOFs (DUT-8(Ni), DUT = Dresden University of Technology, and ELM-11, ELM = Elastic Layer-structured MOF) and one "breathing" MOF (MIL-53(Al), MIL = Material Institute Lavoisier) are shown to cover a wide range of detectable gas concentrations (~20-80%) using this concept. The highest resistance change is observed for composites containing a percolating carbon nanoparticle network (slightly above the percolation threshold concentration). The volume change of the MOF particles disrupts the percolating network, resulting in a colossal resistance change up to 7500%. Repeated threshold detection is particularly feasible using MIL-53(Al) due to its high mechanical and chemical stability, even enabling application of the composite sensor concept in ambient environment for the detection of volatile organic compounds at high concentration levels. PMID- 29182300 TI - CO2-Switchable Membranes Prepared by Immobilization of CO2-Breathing Microgels. AB - Herein, we report the development of a novel CO2-responsive membrane system through immobilization of CO2-responsive microgels into commercially available microfiltration membranes using a method of dynamic adsorption. The microgels, prepared from soap-free emulsion polymerization of CO2-responsive monomer 2 (diethylamino)ethyl methacrylate (DEA), can be reversibly expanded and shrunken upon CO2/N2 alternation. When incorporated into the membranes, this switching behavior was preserved and further led to transformation between microfiltration and ultrafiltration membranes, as indicated from the dramatic changes on water flux and BSA rejection results. This CO2-regulated performance switching of membranes was caused by the changes of water transportation channel, as revealed from the dynamic water contact angle tests and SEM observation. This work represents a simple yet versatile strategy for making CO2-responsive membranes. PMID- 29182301 TI - Electropolymerization Porous Aromatic Framework Film As a Hole-Transport Layer for Inverted Perovskite Solar Cells with Superior Stability. AB - PAF-86 film is electropolymerized (EP) by targeted monomer M1 tethered bifunctional carbozolyl moieties which not only serve in electron donation but also provide effective electrochemical (EC) active sites. The resulting PAF-86 film possesses a fairly compact surface, remarkable stability, efficient hole extraction capacity, and hole-transporting materials (HTMs) for inverted heterojunction perovskite solar cells (PSCs). Likewise, our investigation shows that PAF-86 film based perovskite solar cells (PSCs) retained about 80% power conversion efficiency (PCE) without encapsulation in air, and poly(3,4 ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) based PSCs devices reduce to 4% under the same conditions. More impressively, the electropolymerization approach is convenient, controlled, and operated at ambient conditions which elude post heat-treatments and are appropriate for industrial application. PMID- 29182302 TI - Macroscale and Nanoscale Morphology Evolution during in Situ Spray Coating of Titania Films for Perovskite Solar Cells. AB - Mesoporous titania is a cheap and widely used material for photovoltaic applications. To enable a large-scale fabrication and a controllable pore size, we combined a block copolymer-assisted sol-gel route with spray coating to fabricate titania films, in which the block copolymer polystyrene-block poly(ethylene oxide) (PS-b-PEO) is used as a structure-directing template. Both the macroscale and nanoscale are studied. The kinetics and thermodynamics of the spray deposition processes are simulated on a macroscale, which shows a good agreement with the large-scale morphology of the spray-coated films obtained in practice. On the nanoscale, the structure evolution of the titania films is probed with in situ grazing incidence small-angle X-ray scattering (GISAXS) during the spray process. The changes of the PS domain size depend not only on micellization but also on solvent evaporation during the spray coating. Perovskite (CH3NH3PbI3) solar cells (PSCs) based on sprayed titania film are fabricated, which showcases the suitability of spray-deposited titania films for PSCs. PMID- 29182303 TI - Spontaneous Periodic Delamination of Thin Films To Form Crack-Free Metal and Silicon Ribbons with High Stretchability. AB - Design of electronic materials with high stretchability is of great importance for realizing soft and conformal electronics. One strategy of realizing stretchable metals and semiconductors is to exploit the buckling of materials bonded to elastomers. However, the level of stretchability is often limited by the cracking and fragmentation of the materials that occurs when constrained buckling occurs while bonded to the substrate. Here, we exploit a failure mechanism, spontaneous buckling-driven periodic delamination, to achieve high stretchability in metal and silicon films that are deposited on prestrained elastomer substrates. We find that both globally periodic buckle-delaminated pattern and ordered cracking patterns over large areas are observed in the spontaneously buckle-delaminated thin films. The geometry of periodic delaminated buckles and cracking periodicity can be predicted by theoretical models. By patterning the films into ribbons with widths smaller than the predicted cracking periodicity, we demonstrate the design of crack-free and spontaneous delaminated ribbons on highly prestrained elastomer substrates, which provides a high stretchability of about 120% and 400% in Si and Au ribbons, respectively. We find that the high stretchability is mainly attributed to the largely relaxed strain in the ribbons via spontaneous buckling-driven delamination, as made evident by the small maximum tensile strain in both ribbons, which is measured to be over 100 times smaller than that of the substrate prestrain. PMID- 29182304 TI - Lightweight, Mesoporous, and Highly Absorptive All-Nanofiber Aerogel for Efficient Solar Steam Generation. AB - The global fresh water shortage has driven enormous endeavors in seawater desalination and wastewater purification; among these, solar steam generation is effective in extracting fresh water by efficient utilization of naturally abundant solar energy. For solar steam generation, the primary focus is to design new materials that are biodegradable, sustainable, of low cost, and have high solar steam generation efficiency. Here, we designed a bilayer aerogel structure employing naturally abundant cellulose nanofibrils (CNFs) as basic building blocks to achieve sustainability and biodegradability as well as employing a carbon nanotube (CNT) layer for efficient solar utilization with over 97.5% of light absorbance from 300 to 1200 nm wavelength. The ultralow density (0.0096 g/cm3) of the aerogel ensures that minimal material is required, reducing the production cost while at the same time satisfying the water transport and thermal insulation requirements due to its highly porous structure (99.4% porosity). Owing to its rationally designed structure and thermal-regulation performance, the bilayer CNF-CNT aerogel exhibits a high solar-energy conversion efficiency of 76.3% and 1.11 kg m-2 h-1 at 1 kW m-2 (1 Sun) solar irradiation, comparable or even higher than most of the reported solar steam generation devices. Therefore, the all-nanofiber aerogel presents a new route for designing biodegradable, sustainable, and scalable solar steam generation devices with superb performance. PMID- 29182305 TI - Point-of-Use Nanobiosensor for Detection of Dengue Virus NS1 Antigen in Adult Aedes aegypti: A Potential Tool for Improved Dengue Surveillance. AB - Dengue virus (DENV) and its primary mosquito vectors Aedes spp. have spread to every continent except Antarctica, causing outbreaks and autochthonous transmission in previously disease-free regions. Recently, the spread of other arboviruses carried by invasive Aedes spp., such as Chikungunya and Zika, seem to be following similar trends as DENV and have renewed interest in monitoring and modeling arboviruses within mosquito vectors. Unfortunately, current commercially available detection methods are designed for the diagnosis of DENV in humans or are too expensive and complex for sustainable monitoring. We report a novel electronic nanobiosensor utilizing a single-walled carbon nanotube networks chemiresistor transducer functionalized with antidengue NS1 monoclonal antibodies for rapid detection of the dengue nonstructural protein 1 (NS1). NS1 is a highly conserved protein secreted at high concentrations during viral replication and is a biomarker for DENV infection. NS1 was successfully detected in spiked adult Aedes aegypti homogenate over a broad dynamic range with high sensitivity and selectivity. The biosensor is compatible with "gold-standard" adult mosquito field-collection protocols and generates electronic data that can be readily stored or wirelessly transmitted. Thus, it has potential for remote and real-time monitoring of wild mosquito populations. PMID- 29182306 TI - Imaging Ca2+ with a Fluorescent Rhodol. AB - Ca2+ mediates a host of biochemical and biophysical signaling processes in cells. The development of synthetic, Ca2+-sensitive fluorophores has played an instrumental role in our understanding of the temporal and spatial dynamics of Ca2+. Coupling Ca2+-selective ligands to fluorescent reporters has provided a wealth of excellent indicators that span the visible excitation and emission spectrum and possess Ca2+ affinities suited to a variety of cellular contexts. One underdeveloped area is the use of hybrid rhodamine/fluorescein fluorophores, or rhodols, in the context of Ca2+ sensing. Rhodols are bright and photostable and have good two-photon absorption cross sections (sigmaTPA), making them excellent candidates for incorporation into Ca2+-sensing scaffolds. Here, we present the design, synthesis, and application of rhodol Ca2+ sensor 1 (RCS-1), a chlorinated pyrrolidine-based rhodol. RCS-1 possesses a Ca2+ binding constant of 240 nM and a 10-fold turn response to Ca2+. RCS-1 effectively absorbs infrared light and has a sigmaTPA of 76 GM at 840 nm, 3-fold greater than that of its fluorescein-based counterpart. The acetoxy-methyl ester of RCS-1 stains the cytosol of live cells, enabling observation of Ca2+ fluctuations and cultured neurons using both one- and two-photon illumination. Together, these results demonstrate the utility of rhodol-based scaffolds for Ca2+ sensing using two photon illumination in neurons. PMID- 29182307 TI - Model Study To Assess Softwood Hemicellulose Hydrolysates as the Carbon Source for PHB Production in Paraburkholderia sacchari IPT 101. AB - Softwood hemicellulose hydrolysates are a cheap source of sugars that can be used as a feedstock to produce polyhydroxybutyrates (PHB), which are biobased and compostable bacterial polyesters. To assess the potential of the hemicellulosic sugars as a carbon source for PHB production, synthetic media containing softwood hemicellulose sugars (glucose, mannose, galactose, xylose, arabinose) and the potentially inhibitory lignocellulose degradation products (acetic acid, 5 hydroxymethylfurfural (HMF), furfural, and vanillin) were fermented with the model strain Paraburkholderia sacchari IPT 101. Relative to pure glucose, individual fermentation for 24 h with 20 g/L mannose or galactose exhibited maximum specific growth rates of 97% and 60%, respectively. On the other hand, with sugar mixtures of glucose, mannose, galactose, xylose, and arabinose, the strain converted all sugars simultaneously to reach a maximum PHB concentration of 5.72 g/L and 80.5% PHB after 51 h. The addition of the inhibitor mixture at the following concentration, sodium acetate (2.11 g/L), HMF (0.67 g/L), furfural (0.66 g/L), and vanillin (0.93 g/L), to the sugar mixture stopped the growth entirely within 24 h. Individually, the inhibitors either had no effect or only reduced growth. Moreover, it was found that a bacterial inoculum with high initial cell density (optical density, OD >= 5.6) could overcome the growth inhibition to yield an OD of 13 within 24 h. Therefore, softwood hemicellulose sugars are viable carbon sources for PHB production. Nevertheless, real softwood hemicellulose hydrolysates need detoxification or a high inoculum to overcome inhibitory effects and allow bacterial growth. PMID- 29182308 TI - Targeted MultiNotch MS3 Approach for Relative Quantification of N-Glycans Using Multiplexed Carbonyl-Reactive Isobaric Tags. AB - The recently developed and commercially available carbonyl-reactive tandem mass tags (aminoxyTMT) enable multiplexed quantification of glycans through comparison of reporter ion intensities. However, challenges still exist for collision activated dissociation (CAD) MS/MS based quantification of aminoxyTMT due to the relatively low reporter ion yield especially for glycans with labile structures. To circumvent this limitation, we utilized the unique structural features of N glycan molecules, the common core sugar sequence (HexNAc)2(Man)3, and common m/z of Yn ions generated from different types of precursors by MS/MS and designed a Y1 ion triggered, targeted MultiNotch MS3 relative quantification approach based on aminoxyTMT labeling. This approach was implemented on a nanoHILIC-Tribrid quadrupole-ion trap-Orbitrap platform, which enables prescreening of aminoxyTMT labeled N-glycan precursor ions by Y1 ion fragment ion mass in a higher-energy collisional dissociation (HCD) MS/MS scan and coisolation and cofragmentation of multiple Yn fragment ions that carry the isobaric tags from the inclusion list in the MS/MS/MS scan. Through systematical optimization and evaluation using N glycans released from several glycoprotein standards and human serum proteins, we demonstrated that the Y1 ion triggered, targeted MultiNotch MS3 approach offers improved accuracy, precision, and sensitivity for relative quantification compared to traditional data-dependent MS2 and Y1 ion MS3 quantification methods. PMID- 29182310 TI - Enzyme-Mimetic Antioxidant Luminescent Nanoparticles for Highly Sensitive Hydrogen Peroxide Biosensing. AB - Hydrogen peroxide (H2O2) is an abundant molecule associated with biological functions and reacts with natural enzymes, such as catalase. Even though direct H2O2 measurement can be used to diagnose pathological conditions, such as infection and inflammation, H2O2 quantification further enables the detection of disease biomarkers in enzyme-linked assays (e.g., ELISA) in which enzymatic reactions may generate or consume H2O2. Such a quantification is often measured optically with organic dyes in biological media that suffer, however, from poor stability. Currently, the optical H2O2 biosensing without organic-dyes in biological media and at low, submicromolar, concentrations has yet to be achieved. Herein, we rationally design biomimetic artificial enzymes based on antioxidant CeO2 nanoparticles that become luminescent upon their Eu3+ doping. We vary systematically their diameter from 4 to 16 nm and study their catalase mimetic antioxidant activity, manifested as catalytic H2O2 decomposition in aqueous solutions, revealing a strong nanoparticle surface area dependency. The interaction with H2O2 influences distinctly the particle luminescence rendering them highly sensitive H2O2 biosensors down to 0.15 MUM (5.2 ppb) in solutions for biological assays. Our results link two, so far, unrelated research domains, the CeO2 nanoparticle antioxidant activity and luminescence by rare-earth doping. When these enzyme-mimetic nanoparticles are coupled with alcohol oxidase, biosensing can be extended to ethanol exemplifying how their detection potential can be broadened to additional biologically relevant metabolites. The enzyme mimetic nanomaterial developed here could serve as a starting point of sophisticated in vitro assays toward the highly sensitive detection of disease biomarkers. PMID- 29182312 TI - Potentially Immunogenic Contaminants in Wood-Based and Bacterial Nanocellulose: Assessment of Endotoxin and (1,3)-beta-d-Glucan Levels. AB - Knowledge gaps in the biosafety data of the nanocellulose (NC) for biomedical use through various routes of administration call for closer look at health and exposure evaluation. This work evaluated the potentially immunogenic contaminants levels, for example, endotoxin and (1,3)-beta-d-glucan, in four representative NCs, that is, wood-based NCs and bacterial cellulose (BC). The hot-water extracts were analyzed with ELISA assays, HPSEC-MALLS, GC, and NMR analysis. Varying levels of endotoxin and (1,3)-beta-d-glucan contaminats were found in these widely used NCs. Although the beta-(1,3)-d-glucan was not detected from the NMR spectra due to the small extract samples amount (2-7 mg), the anomerics and highly diastereotopic 6-CH2 signals may suggest the presence of beta-(1,4) linkages with beta-(1,6) branching in the polysaccharides of NCs' hot-water extracts, which were otherwise not detectable in the enzymatic assay. In all, the article highlights the importance of monitoring various water-soluble potentially immunogenic contaminants in NC for biomedical use.

AB - Polymyxins are last-line antibiotics against life-threatening multidrug-resistant Gram-negative bacteria. Unfortunately, polymyxin resistance is increasingly reported, leaving a total lack of therapies. Using lipidomics and transcriptomics, we discovered that polymyxin B induced lipid A deacylation via pagL in both polymyxin-resistant and -susceptible Pseudomonas aeruginosa. Our results demonstrated that the deacylation of lipid A is an "innate immunity" response to polymyxins and a key compensatory mechanism to the aminoarabinose modification to confer high-level polymyxin resistance in P. aeruginosa. Furthermore, cutting-edge neutron reflectometry studies revealed that an assembled outer membrane (OM) with the less hydrophobic penta-acylated lipid A decreased polymyxin B penetration, compared to the hexa-acylated form. Polymyxin analogues with enhanced hydrophobicity displayed superior penetration into the tail regions of the penta-acylated lipid A OM. Our findings reveal a previously undiscovered mechanism of polymyxin resistance, wherein polymyxin-induced lipid A remodeling affects the OM packing and hydrophobicity, perturbs polymyxin penetration, and thereby confers high-level resistance. PMID- 29182313 TI - Biocatalytically Active Thin Films via Self-Assembly of 2-Deoxy-d-ribose-5 phosphate Aldolase-Poly(N-isopropylacrylamide) Conjugates. AB - 2-Deoxy-d-ribose-5-phosphate aldolase (DERA) is a biocatalyst that is capable of converting acetaldehyde and a second aldehyde as acceptor into enantiomerically pure mono- and diyhydroxyaldehydes, which are important structural motifs in a number of pharmaceutically active compounds. However, substrate as well as product inhibition requires a more-sophisticated process design for the synthesis of these motifs. One way to do so is to the couple aldehyde conversion with transport processes, which, in turn, would require an immobilization of the enzyme within a thin film that can be deposited on a membrane support. Consequently, we developed a fabrication process for such films that is based on the formation of DERA-poly(N-isopropylacrylamide) conjugates that are subsequently allowed to self-assemble at an air-water interface to yield the respective film. In this contribution, we discuss the conjugation conditions, investigate the interfacial properties of the conjugates, and, finally, demonstrate a successful film formation under the preservation of enzymatic activity. PMID- 29182314 TI - Mesoporous TiO2 Embedded with a Uniform Distribution of CuO Exhibit Enhanced Charge Separation and Photocatalytic Efficiency. AB - Mixed metal oxide nanoparticles have interesting physical and chemical properties, but synthesizing them with colloidal methods is still challenging and often results in very heterogeneous structures. Here, we describe a simple method to synthesize mesoporous titania nanoparticles implanted with a uniform distribution of copper oxide nanocrystals (CuO@MTs). By calcining a titanium based metal-organic framework (MIL-125) in the presence of Cu ions, we can trap the Cu in the TiO2 matrix. Removal of the organic ligand creates mesoporosity and limits phase separation so that tiny CuO nanocrystals form in the interstices of the TiO2. The CuO@MTs exhibits superior performance for photocatalytic hydrogen evolution (4760 MUmol h-1) that is >90 times larger than pristine titania. PMID- 29182316 TI - Real-Time Monitoring of Endogenous Cysteine Levels In Vivo by near-Infrared Turn on Fluorescent Probe with Large Stokes Shift. AB - Cysteine (Cys), as an important biothiol, plays a major role in many physiological processes like protein synthesis, detoxification and metabolism, and also is closely associated with a variety of diseases; thus the design of novel highly selective and sensitive near-infrared (NIR) fluorescent probes for Cys detection in vivo is of great significance. Herein, we report a selective and sensitive NIR turn-on fluorescent probe (CP-NIR) with large Stokes shift for detecting Cys in vivo. Upon addition of Cys to the solution of the probe, it is absorption wavelength shifts from 550 to 600 nm, accompanying with an obvious enhancement of NIR fluorescence emission centering around 760 nm. This Michael addition reaction-based probe shows a large Stokes shift (160 nm), low detection limit (48 nM), fast response time, and low toxicity. Moreover, this novel NIR probe with good cell permeability was successfully applied to monitoring endogenous Cys in living cells and in a mouse model. PMID- 29182315 TI - Determinants and Prediction of Esterase Substrate Promiscuity Patterns. AB - Esterases receive special attention because of their wide distribution in biological systems and environments and their importance for physiology and chemical synthesis. The prediction of esterases' substrate promiscuity level from sequence data and the molecular reasons why certain such enzymes are more promiscuous than others remain to be elucidated. This limits the surveillance of the sequence space for esterases potentially leading to new versatile biocatalysts and new insights into their role in cellular function. Here, we performed an extensive analysis of the substrate spectra of 145 phylogenetically and environmentally diverse microbial esterases, when tested with 96 diverse esters. We determined the primary factors shaping their substrate range by analyzing substrate range patterns in combination with structural analysis and protein-ligand simulations. We found a structural parameter that helps rank (classify) the promiscuity level of esterases from sequence data at 94% accuracy. This parameter, the active site effective volume, exemplifies the topology of the catalytic environment by measuring the active site cavity volume corrected by the relative solvent accessible surface area (SASA) of the catalytic triad. Sequences encoding esterases with active site effective volumes (cavity volume/SASA) above a threshold show greater substrate spectra, which can be further extended in combination with phylogenetic data. This measure provides also a valuable tool for interrogating substrates capable of being converted. This measure, found to be transferred to phosphatases of the haloalkanoic acid dehalogenase superfamily and possibly other enzymatic systems, represents a powerful tool for low-cost bioprospecting for esterases with broad substrate ranges, in large scale sequence data sets. PMID- 29182317 TI - Twists and Turns of Orbiting and Spinning Metallic Microparticles Powered by Megahertz Ultrasound. AB - Micromotors powered by megahertz ultrasound, first reported about 5 years ago, have lately been considered a promising platform for a wide range of microscale applications, yet we are only at the early stage of understanding their operating mechanisms. Through carefully designed experiments, and by comparing the results to acoustic theories, we present here an in-depth study of the behaviors of particles activated by ultrasound, especially their in-plane orbiting and spinning dynamics. Experiments suggest that metallic microrods orbit in tight circles near the resonance ultrasound frequency, likely driven by localized acoustic streaming due to slightly bent particle shapes. On the other hand, particle spins around their long axes on nodal lines, where phase-mismatched orthogonal sound waves possibly produce a viscous torque. Intriguingly, such a torque spins metal-dielectric Janus microspheres back and forth in an unusual "rocking chair" fashion. Overall, our observations and analysis provide fresh and much needed insights on the interesting particle dynamics in resonating ultrasound and could help with developing more powerful and controllable micromachines with biocompatible energy sources. PMID- 29182318 TI - Heterochiral DNA Strand-Displacement Circuits. AB - The absence of a straightforward strategy to interface native d-DNA with its enantiomer l-DNA-oligonucleotides of opposite chirality are incapable of forming contiguous Watson-Crick base pairs with each other-has enforced a "homochiral" paradigm over the field of dynamic DNA nanotechnology. As a result, chirality, a key intrinsic property of nucleic acids, is often overlooked as a design element for engineering of DNA-based devices, potentially limiting the types of behaviors that can be achieved using these systems. Here we introduce a toehold-mediated strand-displacement methodology for transferring information between orthogonal DNA enantiomers via an achiral intermediary, opening the door for "heterochiral" DNA nanotechnology having fully interfaced d-DNA and l-DNA components. Using this approach, we demonstrate several heterochiral DNA circuits having novel capabilities, including autonomous chiral inversion of DNA sequence information and chirality-based computing. In addition, we show that heterochiral circuits can directly interface endogenous RNAs (e.g., microRNAs) with bioorthogonal l DNA, suggesting applications in bioengineering and nanomedicine. Overall, this work establishes chirality as a design parameter for engineering of dynamic DNA nanotechnology, thereby expanding the types of architectures and behaviors that can be realized using DNA.

AB - The relative contribution of fungi, bacteria, and nirS and nirK denirifiers to nitrous oxide (N2O) emission with unknown isotopic signature from dairy manure compost was examined by selective inhibition techniques. Chloramphenicol (CHP), cycloheximide (CYH), and diethyl dithiocarbamate (DDTC) were used to suppress the activity of bacteria, fungi, and nirK-possessing denitrifiers, respectively. Produced N2O were surveyed to isotopocule analysis, and its 15N site preference (SP) and delta18O values were compared. Bacteria, fungi, nirS, and nirK gene abundances were compared by qPCR. The results showed that N2O production was strongly inhibited by CHP addition in surface pile samples (82.2%) as well as in nitrite-amended core samples (98.4%), while CYH addition did not inhibit the N2O production. N2O with unknown isotopic signature (SP = 15.3-16.20/00), accompanied by delta18O (19.0-26.80/00) values which were close to bacterial denitrification, was also suppressed by CHP and DDTC addition (95.3%) indicating that nirK denitrifiers were responsible for this N2O production despite being less abundant than nirS denitrifiers. Altogether, our results suggest that bacteria are important for N2O production with different SP values both from compost surface and pile core. However, further work is required to decipher whether N2O with unknown isotopic signature is mostly due to nirK denitrifiers that are taxonomically different from the SP-characterized strains and therefore have different SP values rather than also being interwoven with the contribution of the NO-detoxifying pathway and/or of co-denitrification.

AB - Large-scale computations of nuclear magnetic resonance (NMR) shifts for extended paramagnetic solids (pNMR) are reported using the highly efficient Gaussian augmented plane-wave implementation of the CP2K code. Combining hyperfine couplings obtained with hybrid functionals with g-tensors and orbital shieldings computed using gradient-corrected functionals, contact, pseudocontact, and orbital-shift contributions to pNMR shifts are accessible. Due to the efficient and highly parallel performance of CP2K, a wide variety of materials with large unit cells can be studied with extended Gaussian basis sets. Validation of various approaches for the different contributions to pNMR shifts is done first for molecules in a large supercell in comparison with typical quantum-chemical codes. This is then extended to a detailed study of g-tensors for extended solid transition-metal fluorides and for a series of complex lithium vanadium phosphates. Finally, lithium pNMR shifts are computed for Li3V2(PO4)3, for which detailed experimental data are available. This has allowed an in-depth study of different approaches (e.g., full periodic versus incremental cluster computations of g-tensors and different functionals and basis sets for hyperfine computations) as well as a thorough analysis of the different contributions to the pNMR shifts. This study paves the way for a more-widespread computational treatment of NMR shifts for paramagnetic materials. PMID- 29182321 TI - Macrocycle Conformational Sampling by DFT-D3/COSMO-RS Methodology. AB - : To find and calibrate a robust and reliable computational protocol for mapping conformational space of medium-sized molecules, exhaustive conformational sampling has been carried out for a series of seven macrocyclic compounds of varying ring size and one acyclic analogue. While five of them were taken from the MD/LLMOD/force field study by Shelley and co-workers ( Watts , K. S. ; Dalal , P. ; Tebben , A. J. ; Cheney , D. L. ; Shelley , J. C. Macrocycle Conformational Sampling with MacroModel . J. Chem. Inf. MODEL: 2014 , 54 , 2680 - 2696 ), three represent potential macrocyclic inhibitors of human cyclophilin A. The free energy values (GDFT/COSMO-RS) for all of the conformers of each compound were obtained by a composite protocol based on in vacuo quantum mechanics (DFT-D3 method in a large basis set), standard gas-phase thermodynamics, and the COSMO-RS solvation model. The GDFT/COSMO-RS values were used as the reference for evaluating the performance of conformational sampling algorithms: standard and extended MD/LLMOD search (simulated-annealing molecular dynamics with low-lying eigenvector following algorithms, employing the OPLS2005 force field plus GBSA solvation) available in MacroModel and plain molecular dynamics (MD) sampling at high temperature (1000 K) using the semiempirical quantum mechanics (SQM) potential SQM(PM6-D3H4/COSMO) followed by energy minimization of the snapshots. It has been shown that the former protocol (MD/LLMOD) may provide a more complete set of initial structures that ultimately leads to the identification of a greater number of low-energy conformers (as assessed by GDFT/COSMO-RS) than the latter (i.e., plain SQM MD). The CPU time needed to fully evaluate one medium sized compound (~100 atoms, typically resulting in several hundred or a few thousand conformers generated and treated quantum-mechanically) is approximately 1,000-100,000 CPU hours on today's computers, which transforms to 1-7 days on a small-sized computer cluster with a few hundred CPUs. Finally, our data sets based on the rigorous quantum-chemical approach allow us to formulate a composite conformational sampling protocol with multiple checkpoints and truncation of redundant structural data that offers superior insights at affordable computational cost. PMID- 29182322 TI - Controlling Photochemistry via Isotopomers and IR Pre-excitation. AB - It is a photochemist's dream to be able to photoinduce a reaction of a specific molecular species in an ensemble of similar but not identical ones. The problem is that similar molecules often exhibit nearly identical UV-Vis absorption spectra, making them difficult or impossible to distinguish or to select spectroscopically. The ultrafast VIPER (VIbrationally Promoted Electronic Resonance) pulse sequence allows to pick a single species for electronic excitation based on its infrared spectrum. The latter usually shows more features, allowing the discrimination between species than the UV-Vis spectrum. Here, we show that it is possible to induce and monitor species-selective photochemistry even for molecules with virtually identical UV-Vis spectra, which is the case for isotopomers. Next to isotope-selective photochemistry in solution, applications to orthogonal photo-uncaging and species-selective spectroscopy and photochemistry in mixtures are within reach. PMID- 29182324 TI - Protein-Ligand Dissociation Simulated by Parallel Cascade Selection Molecular Dynamics. AB - We investigated the dissociation process of tri-N-acetyl-d-glucosamine from hen egg white lysozyme using parallel cascade selection molecular dynamics (PaCS-MD), which comprises cycles of multiple unbiased MD simulations using a selection of MD snapshots as the initial structures for the next cycle. Dissociation was significantly accelerated by PaCS-MD, in which the probability of rare event occurrence toward dissociation was enhanced by the selection and rerandomization of the initial velocities. Although this complex was stable during 1 MUs of conventional MD, PaCS-MD easily induced dissociation within 100-101 ns. We found that velocity rerandomization enhances the dissociation of triNAG from the bound state, whereas diffusion plays a more important role in the unbound state. We calculated the dissociation free energy by analyzing all PaCS-MD trajectories using the Markov state model (MSM), compared the results to those obtained by combinations of PaCS-MD and umbrella sampling (US), steered MD (SMD) and US, and SMD and the Jarzynski equality, and experimentally determined binding free energy. PaCS-MD/MSM yielded results most comparable to the experimentally determined binding free energy, independent of simulation parameter variations, and also gave the lowest standard errors.

AB - We performed a molecular modeling analysis of 100 nucleotide-like bisphosphates and 46 non-nucleotide arylurea derivatives previously reported as P2Y1R binders using the recently solved hP2Y1R structures. We initially docked the compounds at the X-ray structures and identified the binding modes of representative compounds highlighting key patterns in the structure-activity relationship (SAR). We subsequently subjected receptor complexes with selected key agonists (2MeSADP and MRS2268) and antagonists (MRS2500 and BPTU) to membrane molecular dynamics (MD) simulations (at least 200 ns run in triplicate, simulation time 0.6-1.6 MUs per ligand system) while considering alternative protonation states of nucleotides. Comparing the temporal evolution of the ligand-protein interaction patterns with available site-directed mutagenesis (SDM) data and P2Y1R apo state simulation provided further SAR insights and suggested reasonable explanations for loss/gain of binding affinity as well as the most relevant charged species for nucleotide ligands. The MD analysis also predicted local conformational changes required for the receptor inactive state to accommodate nucleotide agonists.

AB - Reactions of tin and manganese in a lanthanum/nickel eutectic melt in alumina crucibles produce La11Mn13-x-yNixAlySn4-delta (0 <= x <= 3.6; 2.5 <= y <= 4.9; 0.6 <= delta <= 1.1) phases with the stoichiometry dependent on the reactant ratio. These compounds crystallize in a new tetragonal structure type in space group P4/mbm, with a = 8.4197(1) A, c = 19.2414(3) A, and Z = 2 for La11Mn8.2Ni0.8Al4Sn3.3. The structure can be viewed as an intergrowth between La6Co11Ga3-type layers and Cr5B3-type La/Sn slabs. This system represents a unique playground to study the itinerant magnetism of diluted icosahedral Mn layers. The dilution of manganese sites in the Mn/Ni/Al layer with nonmagnetic elements has a significant effect on magnetic properties, with low Mn content analogues being paramagnetic and higher Mn content analogues such as La11Mn10Al3Sn3.4 exhibiting spin-glass behavior with a freezing transition at 20 K. The lack of long-range magnetic ordering is confirmed by heat capacity and resistivity measurements. PMID- 29182326 TI - Phase Inversion Directly Induced Tight Ultrafiltration (UF) Hollow Fiber Membranes for Effective Removal of Textile Dyes. AB - This study has demonstrated the application of tight ultrafiltration (UF) membranes for effective removal of textile dyes from water at a low pressure. Novel UF hollow fiber membranes with well-defined nanopores and surface charges were developed via a single-step spinning process without any post-treatment. The newly developed tight UF hollow fibers not only possess a small mean pore diameter of 1.0-1.3 nm with a molecular weight cutoff (MWCO) of 1000-2000 Da but also have a high pure water permeability (PWP) of 82.5-117.6 L m-2 h-1 bar-1. Through the synergistic effects of size exclusion and charge repulsion, the novel UF hollow fibers can effectively remove various dyes with impressive rejections of 93.2-99.9% at 1 bar. At the same time, more than 92% of inorganic salts (i.e., NaCl and Na2SO4) would permeate through the fibers, reducing the detrimental effects of concentration polarization and providing an attracted avenue for salts reuse. The tight UF hollow fibers also exhibit robust performance in a continuous operation of 170 h or at a high feed recovery of 90%. The fouled fibers can be easily regenerated by backwash of water with a flux recovery of larger than 92%. The newly developed tight UF hollow fiber membranes display huge potential for treating textile wastewater and other impaired effluents because of their great separation performance and simple fabrication process. PMID- 29182327 TI - Nonredox Metal Ions Promoted Olefin Epoxidation by Iron(II) Complexes with H2O2: DFT Calculations Reveal Multiple Channels for Oxygen Transfer. AB - Nonredox metal ions play significant roles in a wide range of biological and chemical oxidations in which they can modulate the oxidative reactivity of those redox metal ions. With environmentally benign H2O2 as oxidant, the influence of nonredox metal ions on an iron(II) complex mediated olefin epoxidation was investigated through experimental studies and theoretical calculations. It was found that adding nonredox metal ions like Sc3+ can substantially improve the oxygen transfer efficiency of the iron(II) complex toward cyclooctene epoxidation even in the presence of certain amount of water. In 18O-labeling experiments with 18O water, the presence of Sc3+ provided a higher 18O incorporation in epoxide. In UV-vis studies, it was found that the presence of Sc3+ makes both FeIII-OOH and FeIV?O species unstable. Density functional theory calculations further disclosed that, in the presence of Sc(OTf)3, the Sc3+ adducts of FeIII-OOH and FeIV?O species are capable of epoxidizing olefin as well as FeV?O species, thus opening multiple channels for oxygenation. In particular, in the pathway of cyclooctene epoxidation, the FeIV?O/Sc3+ adduct-mediated epoxidation is more energetically favorable than that of the FeV?O species (12.2 vs 17.2 kcal/mol). This information may implicate that the presence of certain nonredox metal ions can facilitate these redox metal ions mediating biological and chemical oxidations happening at a relatively low oxidation state, which is more energetically accessible. PMID- 29182328 TI - Copper-Catalyzed Alkylation of Aliphatic Amines Induced by Visible Light. AB - Although the alkylation of an amine by an alkyl halide serves as a "textbook example" of a nucleophilic substitution reaction, the selective mono-alkylation of aliphatic amines by unactivated, hindered halides persists as a largely unsolved challenge in organic synthesis. We report herein that primary aliphatic amines can be cleanly mono-alkylated by unactivated secondary alkyl iodides in the presence of visible light and a copper catalyst. The method operates under mild conditions (-10 degrees C), displays good functional-group compatibility, and employs commercially available catalyst components. A trapping experiment with TEMPO is consistent with C-N bond formation via an alkyl radical in an out of-cage process.

AB - We present a simple expression and its derivation for reaction rate coefficients for cold anisotropic collision experiments based on adiabatic variational theory and time-independent non-Hermitian scattering theory. We demonstrate that only the eigenenergies of the resulting one-dimensional Schrodinger equation for different complex adiabats are required. The expression is applied to calculate the Penning ionization rate coefficients of an excited metastable helium atom with molecular hydrogen in an energy range spanning from hundreds of kelvins down to the millikelvin regime. Except for trivial quantities like the masses of the nuclei and the bond length of the diatomic molecule participating in the collision, one needs as input data only the complex potential energy surface (CPES). In calculations, we used recently obtained ab initio CPES by D. Bhattacharya et al. ( J. Chem. Theory Comput. 2017 , 13 , 1682 - 1690 ) without fitting parameters. The results show good accord with current measurements ( Nat. Phys. 2017 , 13 , 35 - 38 ). PMID- 29182330 TI - Highly Efficient Interception and Precipitation of Uranium(VI) from Aqueous Solution by Iron-Electrocoagulation Combined with Cooperative Chelation by Organic Ligands. AB - A new strategy combining iron-electrocoagulation and organic ligands (OGLs) cooperative chelation was proposed to screen and precipitate low concentrations (0-18.52 MUmol/L) of uranium contaminant in aqueous solution. We hypothesized that OGLs with amino, hydroxyl, and carboxyl groups hydrophobically/hydrophilically would realize precuring of uranyl ion at pH < 3.0, and the following iron-electrocoagulation would achieve faster and more efficient uranium precipitation. Experimentally, the strategy demonstrated highly efficient uranium(VI) precipitation efficiency, especially with hydrophilic macromolecular OGLs. The uranium removal efficiency at optimized experimental condition reached 99.65%. The decrease of zeta potential and the lattice enwrapping between U-OGLs chelates and flocculation precursor were ascribed to the enhanced uranium precipitation activity. Uranium was precipitated as oxides of U(VI) or higher valences that were easily captured in aggregated micelles under low operation current potential. The actual uranium tailing wastewater was treated, and a satisfied uranium removal efficiency of 99.02% was discovered. After elution of the precipitated flocs, a concentrated uranium solution (up to 106.52 MUmol/L) with very few other metallic impurities was obtained. Therefore, the proposed strategy could remove uranium and concentrate it concurrently. This work could provide new insights into the purification and recovery of uranium from aqueous solutions in a cost-effective and environmentally friendly process.

AB - Six new polyoxygenated steroids (1-6) along with clathriol (7) were isolated from the Korean marine sponge Clathria gombawuiensis. Based upon the results of combined spectroscopic analyses, the structures of gombasterols A-F (1-6) were elucidated to be those of highly oxygenated steroids possessing a 3beta,4alpha,6alpha,7beta-tetrahydroxy or equivalent (7beta-sodium O-sulfonato for 3) substitution pattern and a C-15 keto group as common structural motifs. The relative and absolute configurations of these steroids, including the rare 14beta configuration of 1-4, were determined by a combination of NOESY, J-based analyses, the 2-methoxy-2-(trifluoromethyl)phenylacetic acid (MTPA) method, and X ray crystallographic analysis. The absolute configuration of 7 was also assigned by these methods. These compounds moderately enhanced 2-deoxy-2-[(7-nitro-2,1,3 benzoxadiazol-4-yl)amino]-d-glucose (2-NBDG) uptake in differentiated 3T3-L1 adipocytes and phosphorylation of AMP-activated protein kinase (AMPK) and acetyl CoA carboxylase (ACC) in differentiated mouse C2C12 skeletal myoblasts.

AB - Maturity-onset diabetes of the young (MODY) is an inherited monogenic type of diabetes. Genetic mutations in MODY often cause nonsynonymous changes that directly lead to the functional distortion of proteins and the pathological consequences. Herein, we proposed that the inherited mutations found in a MODY family could cause a disturbance of protein abundance, specifically in serum. The serum samples were collected from a Uyghur MODY family through three generations, and the serum proteins after depletion treatment were examined by quantitative proteomics to characterize the MODY-related serum proteins followed by verification using target quantification of proteomics. A total of 32 serum proteins were preliminarily identified as the MODY-related. Further verification test toward the individual samples demonstrated the 12 candidates with the significantly different abundance in the MODY patients. A comparison of the 12 proteins among the sera of type 1 diabetes, type 2 diabetes, MODY, and healthy subjects was conducted and revealed a protein signature related with MODY composed of the serum proteins such as SERPINA7, APOC4, LPA, C6, and F5.

AB - The pathophysiology underlying the autoimmune disease type 1 diabetes (T1D) is poorly understood. Obtaining an accurate proteomic profile of the T helper cell population is essential for understanding the pathogenesis of T1D. Here, we performed in-depth proteomic profiling of peripheral CD4+ T cells in a pediatric cohort to identify cellular signatures associated with the onset of T1D. Using only 250 000 CD4+ T cells per patient, isolated from biobanked PBMC samples, we identified nearly 6000 proteins using deep-proteome profiling with LC-MS/MS data independent acquisition. Our analysis revealed an inflammatory signature in patients with T1D; this signature is characterized by circulating mediators of neutrophils, platelets, and the complement system. This signature likely reflects the inflammatory extracellular milieu, which suggests that activation of the innate immune system plays an important role in disease onset. Our results emphasize the potential value of using high-resolution LC-MS/MS to investigate limited quantities of biobanked samples to identify disease-relevant proteomic patterns. Proteomic profiles of 114 individuals have been deposited in a comprehensive portable repository serving as a unique resource for CD4+ T cell expression in the context of both health and T1D disease.

AB - Inspired by cytoskeletal scaffolds that sense and respond dynamically to environmental changes and chemical inputs with a unique capacity for reconfiguration, we propose a strategy that allows the dynamic and reversible control of the growth and breakage of micron-scale synthetic DNA structures upon pH changes. We do so by rationally designing a pH-responsive system composed of synthetic DNA strands that act as pH sensors, regulators, and structural elements. Sensor strands can dynamically respond to pH changes and route regulatory strands to direct the self-assembly of structural elements into tubular structures. This example represents the first demonstration of the reversible assembly and disassembly of micron-scale DNA scaffolds using an external chemical input other than DNA. The capacity to reversibly modulate nanostructure size may promote the development of smart devices for catalysis or drug-delivery applications.

AB - Direct oxidation of alpha-CH2 group of free amines is hard to achieve due to the higher reactivity of amine moiety. Therefore, oxidation of amines involves the use of sophisticated metallic reagents/catalyst in the presence or absence of hazardous oxidants under sensitive reaction conditions. A novel method for direct C-H oxygenation of aliphatic amines through a metal-free activation of molecular oxygen has been developed. Both activated and unactivated free amines were oxygenated efficiently to provide a wide variety of amides (primary, secondary) and lactams under operationally simple conditions without the aid of metallic reagents and toxic oxidants. The method has been applied to the synthesis of highly functionalized amide-containing medicinal drugs, such as O-Me-alibendol and -buclosamide.

AB - The controllability of switching conductive filaments is one of the central issues in the development of reliable metal-oxide resistive memory because the random dynamic nature and formation of the filaments pose an obstacle to desirable switching performance. Here, we introduce a simple and novel approach to control and form a single silicon nanocrystal (Si-NC) filament for use in SiOx memory devices. The filament is formed with a confined vertical nanoscale gap by using a well-defined single vertical truncated conical nanopore (StcNP) structure. The physical dimensions of the Si-NC filaments such as number, size, and length, which have a significant influence on the switching properties, can be simply engineered by the breakdown of an Au wire through different StcNP structures. In particular, we demonstrate that the designed SiOx memory junction with a StcNP of pore depth of ~75 nm and a bottom diameter of ~10 nm exhibited a switching speed of up to 6 ns for both set and reset process, significantly faster than reported SiOx memory devices. The device also exhibited a high ON-OFF ratio, multistate storage ability, acceptable endurance, and retention stability. The influence of the physical dimensions of the StcNP on the switching features is discussed based on the simulated temperature profiles of the Au wire and the nanogap size generated inside the StcNP structure during electromigration.

AB - Understanding the nature of covalent (band-like) vs ionic (atomic-like) electrons in metal oxides continues to be at the forefront of research in the physical sciences. In particular, the development of a coherent and quantitative model of bonding and electronic structure for the lanthanide dioxides, LnO2 (Ln = Ce, Pr, and Tb), has remained a considerable challenge for both experiment and theory. Herein, relative changes in mixing between the O 2p orbitals and the Ln 4f and 5d orbitals in LnO2 are evaluated quantitatively using O K-edge X-ray absorption spectroscopy (XAS) obtained with a scanning transmission X-ray microscope and density functional theory (DFT) calculations. For each LnO2, the results reveal significant amounts of Ln 5d and O 2p mixing in the orbitals of t2g (sigma bonding) and eg (pi-bonding) symmetry. The remarkable agreement between experiment and theory also shows that significant mixing with the O 2p orbitals occurs in a band derived from the 4f orbitals of a2u symmetry (sigma-bonding) for each compound. However, a large increase in orbital mixing is observed for PrO2 that is ascribed to a unique interaction derived from the 4f orbitals of t1u symmetry (sigma- and pi-bonding). O K-edge XAS and DFT results are compared with complementary L3-edge and M5,4-edge XAS measurements and configuration interaction calculations, which shows that each spectroscopic approach provides evidence for ground state O 2p and Ln 4f orbital mixing despite inducing very different core-hole potentials in the final state. PMID- 29182344 TI - Light Emission from Gold Nanoparticles under Ultrafast Near-Infrared Excitation: Thermal Radiation, Inelastic Light Scattering, or Multiphoton Luminescence? AB - Gold nanoparticles emit broad-band upconverted luminescence upon irradiation with pulsed infrared laser radiation. Although the phenomenon is widely observed, considerable disagreement still exists concerning the underlying physics, most notably over the applicability of concepts such as multiphoton absorption, inelastic scattering, and interband vs intraband electronic transitions. Here, we study single particles and small clusters of particles by employing a spectrally resolved power-law analysis of the irradiation-dependent emission as a sensitive probe of these physical models. Two regimes of emission are identified. At low irradiance levels of kW/cm2, the emission follows a well-defined integer-exponent power law suggestive of a multiphoton process. However, at higher irradiance levels of several kW/cm2, the nonlinearity exponent itself depends on the photon energy detected, a tell-tale signature of a radiating heated electron gas. We show that in this regime, the experiments are incompatible with both interband transitions and inelastic light scattering as the cause of the luminescence, whereas they are compatible with the notion of luminescence linked to intraband transitions.

AB - A procedure for formation of catalytic SiO2 substrate adhesive layer patterns and selective electrochemical metal deposition on the catalyst images was investigated. A photoreactive solution containing a diazonaphthoquinone sulfonate ester and Ti and Cu complexes was developed to deposit Cu catalyst-TiO2 adhesive layer latent images on glass. Sub-micrometer/micrometer scale positive tone photoactive TiCu complex film patterns were formed using a conventional photolithography technique. The Cu ions in 40-50 nm thick Ti and Cu oxide layers formed by pyrolysis of the TiCu complex films were reduced, residual Cu displaced with Pd then the porous Ti oxide structure filled and plated with Cu by selective electroless then electrolytic plating. Annealing the Cu plating filled TiO2 layers on glass resulted in formation of a smooth Ti3+/Cu1+ oxide interface that enabled formation of 20 MUm thick Cu deposits on glass substrate with up to 1 kN/m adhesion strength. The adhesion strength was attributed to chemical bonding of Ti3+ and Cu1+ oxides to the glass and Ti4+ oxide to the Cu plating that was formed upon annealing the Cu filled TiO2 interlayer. Furthermore, a dip coating procedure was adapted that allowed copper film deposition on the entire surface of a 300 MUm thick glass substrate with 50 MUm in diameter holes enabling formation of electrically conductive through glass substrate interconnects.

PMID- 29182347 TI - Efficient and Adaptive Methods for Computing Accurate Potential Surfaces for Quantum Nuclear Effects: Applications to Hydrogen-Transfer Reactions. AB - We present two sampling measures to gauge critical regions of potential energy surfaces. These sampling measures employ (a) the instantaneous quantum wavepacket density, an approximation to the (b) potential surface, its (c) gradients, and (d) a Shannon information theory based expression that estimates the local entropy associated with the quantum wavepacket. These four criteria together enable a directed sampling of potential surfaces that appears to correctly describe the local oscillation frequencies, or the local Nyquist frequency, of a potential surface. The sampling functions are then utilized to derive a tessellation scheme that discretizes the multidimensional space to enable efficient sampling of potential surfaces. The sampled potential surface is then combined with four different interpolation procedures, namely, (a) local Hermite curve interpolation, (b) low-pass filtered Lagrange interpolation, (c) the monomial symmetrization approximation (MSA) developed by Bowman and co-workers, and (d) a modified Shepard algorithm. The sampling procedure and the fitting schemes are used to compute (a) potential surfaces in highly anharmonic hydrogen bonded systems and (b) study hydrogen-transfer reactions in biogenic volatile organic compounds (isoprene) where the transferring hydrogen atom is found to demonstrate critical quantum nuclear effects. In the case of isoprene, the algorithm discussed here is used to derive multidimensional potential surfaces along a hydrogen-transfer reaction path to gauge the effect of quantum-nuclear degrees of freedom on the hydrogen-transfer process. Based on the decreased computational effort, facilitated by the optimal sampling of the potential surfaces through the use of sampling functions discussed here, and the accuracy of the associated potential surfaces, we believe the method will find great utility in the study of quantum nuclear dynamics problems, of which application to hydrogen-transfer reactions and hydrogen-bonded systems is demonstrated here.

AB - We report simulation results regarding the hydration process of the guanidinium cation in water droplets and in bulk liquid water, at a low concentration of 0.03 M, performed using a polarizable approach to model both water/water and ion/water interactions. In line with earlier theoretical studies, our simulations show a preferential orientation of guanidinium at water-vacuum interfaces, i.e., a parallel orientation of the guanidinium plane to the aqueous surface. In an apparent contradiction with earlier simulation studies, we show also that guanidinium has a stronger propensity for the cores of aqueous systems than the ammonium cation. However, our bulk simulation conditions correspond to weaker cation concentrations than in earlier studies, by 2 orders of magnitude, and that the same simulations performed using a standard nonpolarizable force field leads to the same conclusion. From droplet data, we extrapolate the guanidinium single hydration enthalpy value to be -82.9 +/- 2.2 kcal mol-1. That is about half as large as the sole experimental estimate reported to date, about -144 kcal mol-1. Our result yields a guanidinium absolute bulk hydration free energy at ambiant conditions to be -78.4 +/- 2.6 kcal mol-1, a value smaller by 3 kcal mol-1 compared to ammonium. The relatively large magnitude of our guanidinium hydration free energy estimate suggests the Gdm+ protein denaturing properties to result from a competition between the cation hydration effects and the cation/protein interactions, a competition that can be modulated by weak differences in the protein or in the cation chemical environment.

AB - Ten new cephalotane-type diterpenoids, cephanolides A-J (1-10), and two known analogues were isolated and characterized from Cephalotaxus sinensis. Compounds 1 3 represent the first examples of A-ring-contracted cephalotane-type dinorditerpenoids, and compound 4 is an A-ring-contracted norditerpenoid. The biosynthetic pathways for compounds 1-4 are postulated with the coexisting cephalotane-type troponoids as the precursors. Compounds 11 and 12 showed significant cytotoxicities against a panel of tumor cell lines (A549, KB, HL-60, and HT-29) with IC50 values ranging from 0.464 to 6.093 MUM. PMID- 29182350 TI - Using the 4 Pillars to increase vaccination among high-risk adults: who benefits? AB - OBJECTIVES: To compare changes in vaccination rates (pneumococcal polysaccharide vaccine [PPSV]; tetanus, diphtheria, and pertussis [Tdap] vaccine; and influenza vaccine) among high-risk adults following an intervention (June 1, 2013, to January 31, 2015) that used the 4 Pillars Practice Transformation Program (4 Pillars Program). STUDY DESIGN: Post hoc analysis of data from a randomized controlled cluster trial. METHODS: Eighteen primary care practices received staff education, guidance for using the 4 Pillars Program, and support for a practice immunization champion. Paired t tests were used to compare vaccination rates separately for those with diabetes, chronic lung or chronic heart disease, or other high-risk conditions. Student's t tests were used to compare vaccination rates across high-risk conditions. Generalized estimating equation modeling was used to determine the likelihood of vaccination. RESULTS: Based on International Classification of Diseases, Ninth Revision, Clinical Modification codes, 4737 patients aged 18 to 64 years were identified as having diabetes (n = 1999), chronic heart disease (n = 658), chronic lung disease (n = 1682), or another high risk condition (n = 764). PPSV uptake increased by 12.2 percentage points (PP), Tdap vaccination increased by 11.4 PP, and influenza vaccination increased by 4.8 PP. In regression analyses, patients with diabetes (odds ratio [OR], 2.2; 95% CI, 1.80-2.73), chronic lung disease (OR, 1.50; 95% CI, 1.21-1.87), or chronic heart disease (OR, 1.32; 95% CI, 1.02-1.71) were more likely to receive PPSV than those without the respective high-risk condition. Those with diabetes (OR, 1.14; 95% CI, 1.01-1.28) or chronic lung disease (OR, 1.14; 95% CI, 1.01-1.30) were more likely to receive an influenza vaccine than those without the respective condition. The likelihood of Tdap vaccination was not significantly associated with any of the chronic conditions tested. CONCLUSIONS: An intervention including the 4 Pillars Program was associated with significant increases in vaccination of high-risk adults. However, the overall uptake of recommended vaccines for those with high-risk conditions remained below national goals. PMID- 29182351 TI - The influence of provider characteristics and market forces on response to financial incentives. AB - OBJECTIVES: Alternative payment models, such as accountable care organizations, use financial incentives as levers for change to facilitate the transition from volume to value. However, implementation raises concerns about adverse changes in market competition and the resultant physician response. We sought to identify physician characteristics and market-level factors associated with variation in response to financial incentives for cancer care that may ultimately be leveraged in risk-shared payment models. STUDY DESIGN: Retrospective cohort study of physicians providing minimally invasive bladder cancer procedures to fee-for service Medicare beneficiaries. METHODS: We examined the relationship of between group differences in market-level factors (competition [Herfindahl-Hirschman Index (HHI)] and provider density) and physician-level factors (use of unique billing codes, number of billing codes per patient, and competing financial interest) to responsiveness to financial incentives. RESULTS: Incentive responsive providers had increased odds (odds ratio [OR], 1.19; 95% CI, 1.04 1.35) of practicing in markets with the highest quartile of provider density but not HHI (OR, 0.96; 95% CI, 0.87-1.05). Incentive-responsive providers were more likely to bill in the highest quartile for unique codes (OR, 1.49; 95% CI, 1.32 1.69) and codes per patient (OR, 1.18; 95% CI, 1.11-1.25) and less likely to have a competing financial interest (OR, 0.76; 95% CI, 0.72-0.81). CONCLUSIONS: Responsiveness to financial incentives in cancer care is associated with high market provider density, profit-maximizing billing behavior, and lack of competing financial ownership interests. Identifying physicians and markets responsive to financial incentives may ultimately promote the successful implementation of alternative payment models in cancer care. PMID- 29182352 TI - Patients' perspectives of care management: a qualitative study. AB - OBJECTIVES: Risk-stratified care management is a cornerstone of patient-centered medical home models, but studies on patients' perspectives of care management are scarce. We explored patients' experiences with care management, what they found useful, and what needs improvement. STUDY DESIGN: Semi-structured qualitative telephone interviews. METHODS: We interviewed 43 high-risk patients or their caregivers who were receiving care management from 11 practices in CMS' Comprehensive Primary Care initiative, provided by nurse care managers (9 practices) or the physician (2 [solo] practices). RESULTS: Patients' perceptions of care management were mixed. Patients who had regular contact with, and a desire to work with, their care manager valued the care management services provided. These patients valued care managers who listened to them and explained their conditions and options in lay terms, helped them navigate the healthcare system and community resources, and followed up after hospitalizations. However, one-fifth of the patients in practices that used nurse care managers could not identify their care manager although we: 1) sampled patients who had recent contact with their care manager and 2) defined the care manager's roles and provided examples of typical care management activities. Patients' interactions with care managers from health plans and hospitals contributed to confusion. CONCLUSIONS: Practices can improve patient buy-in for care management through in person introductions to care managers by their physicians, offering care management to patients who need and are interested in it, broader agreement about terminology and the role of care managers and care plans, and better coordination with care management from insurers and hospitals. PMID- 29182353 TI - Impact of health reform on young adult prescription medication utilization. AB - OBJECTIVES: To assess the impact of the Affordable Care Act dependent coverage provision on outpatient prescription expenditures among young adults and to characterize medication types that are prescribed for young adults. STUDY DESIGN: Quasi-experimental. METHODS: Using data from the Medical Expenditure Panel Survey from 2007 to 2009 and 2011 to 2013, difference-in-differences (DID) analyses estimated the provision's impact among young adults aged 19 to 25 years versus those aged 26 to 34 years. Five outcomes related to prescription medication access and utilization were evaluated, including whether young adults were unable to get necessary medications in the past year due to cost and whether there were changes in total, out-of-pocket (OOP), and private expenditures and the share of total expenditures paid OOP. DID analyses were also carried out for medication expenditures by class. RESULTS: There were a total of 19,165 young adults aged 19 to 25 years and 23,892 aged 26 to 34 years. After adjusting for demographic and socioeconomic factors, provision implementation (DID coefficient P <=.05) was associated with an increase in total expenditures (by 3.8 percentage points), including those paid by private insurance (7.6 percentage points), and decreases in OOP expenditures and the share of total expenditures paid OOP (4.4 and 1.2 percentage points, respectively). Commonly used medications were anti-infectives, central nervous system agents, and hormones. Expenditures significantly increased for anti-infectives and decreased for hormones and psychotherapeutics. CONCLUSIONS: The dependent coverage provision was associated with an increase in prescription medication expenditures, especially for anti-infectives, among young adults. The amount of expenditures paid by private insurers increased, whereas they decreased for OOP spending. PMID- 29182354 TI - Reframing the unaffordability debate: patient responsibility for physician care. AB - OBJECTIVES: Public discussion suggests that rising out-of-pocket costs have dramatically reduced the value of insurance and led to patients doing without needed care. Our aim was to ascertain trends in patient responsibility for cost sharing. STUDY DESIGN: We used data from an organization that serves over 78,000 healthcare providers and has access to visit-level data, including the amounts paid by patients. These practices are broadly representative of physicians and patients nationally. METHODS: We analyzed trends in patient obligations among a cohort of about 21,000 providers in 1078 practices who had used athenahealth software since 2011, including primary care physicians, obstetricians and gynecologists, surgeons, and some other specialists. Our analysis focused on what commercially insured patients pay out of pocket when seeking ambulatory care. RESULTS: The average patient obligation for approximately 2.5 million primary care visits each year rose from $23.52 per visit in 2011 to $26.40 per visit in 2015, for an overall increase of $2.88, or about 3% annually. This rate of increase is moderate and below growth in overall healthcare spending during the same time period. CONCLUSIONS: Average increases in patient obligations for outpatient visits in recent years have been fairly moderate, and multiple sources of survey data suggest that consumers' concerns about overall affordability are decreasing. The high cost of healthcare continues to pose challenges, both at the individual level and for society as a whole. Nevertheless, it is important that potential strategies to improve affordability are informed by trends in patient obligations. PMID- 29182355 TI - Electronic reminder's role in promoting human papillomavirus vaccine use. AB - OBJECTIVES: To study the association of using an electronic health record (EHR)'s clinical reminder functionality with increased human papillomavirus (HPV) vaccine administration among US office-based physicians. STUDY DESIGN: National Ambulatory Medical Care Survey data from 2007-2012 were pooled together to determine if EHR systems that employ clinical reminders are associated with increased immunization rates in different populations. METHODS: The administration of HPV vaccine served as the dependent variable, with the EHR reminder being the primary independent variable of interest. Logit regression was used to assess the relationship between using EHR reminders and HPV vaccine administration. RESULTS: Analyses indicated that compared with physicians without clinical reminder functions, physicians with clinical reminder functions were more likely to order HPV vaccines. Clinical reminder functions were particularly effective at increasing HPV vaccine use among adolescent males. CONCLUSIONS: Overall, physicians who report using clinical reminders were more likely to order HPV immunizations. However, the association of clinical reminders with HPV immunizations was not significant in the younger adolescent subpopulation. Further, given that HPV incidence decreases significantly even with small gains in vaccination rates, the increase in HPV immunizations found in the male population aged 11 to 21 years is promising. Therefore, targeting males to receive HPV vaccination immunizations through clinical reminders provides a positively disproportionate return on vaccination rates and disease burden. PMID- 29182356 TI - Improving antibiotic stewardship: a stepped-wedge cluster randomized trial. AB - OBJECTIVES: Antibiotic stewardship is key to optimizing patient outcomes and affordable care. The study objective was to examine the effect of provider education and clinical decision support (CDS) on antibiotic prescribing for acute sinusitis among providers of varying experience. STUDY DESIGN: A stepped-wedge cluster randomized intervention to evaluate antibiotic use for acute sinusitis encounters at 126 Kaiser Permanente Southern California clinics between September 2014 and April 2015. METHODS: The primary outcome was receipt of an antibiotic prescription. Multivariate analysis adjusted for patient, provider, and medical center characteristics. Secondary analyses described sinusitis and other common upper respiratory infection (URI) diagnoses and antibiotic use during the study period compared with prior years. Chart review of a random sample reported the proportion of encounters receiving guideline-concordant antibiotics. RESULTS: Analysis of 21,949 encounters (10,491 pre- and 11,458 post intervention) showed CDS reduced the use of antibiotics (adjusted odds ratio [AOR], 0.78; 95% CI, 0.71 0.87), although the pre-post absolute difference was small (85.9% vs 83.9%, respectively). Education had a large initial effect (AOR, 0.51; 95% CI, 0.46 0.57), which did not persist. Increasing years of provider experience raised the rates of antibiotic prescribing, but did not have a significant interaction with CDS (P = .19). The effect of CDS varied by medical center (P <.001). In addition, sinusitis diagnoses decreased post intervention, with no overall increase in antibiotic prescribing for URI diagnoses. Lastly, guideline-concordant antibiotic use increased by 14%. CONCLUSIONS: Provider education and CDS improved antibiotic stewardship and changed diagnosis patterns. The benefits of education were brief, and CDS effectiveness varied by medical center. PMID- 29182357 TI - Changes in cardiovascular care provision after the Affordable Care Act. AB - OBJECTIVES: Physicians are gatekeepers to preventive care recommended by the US Preventive Services Task Force (USPSTF). We aimed to determine whether the Affordable Care Act (ACA) was associated with changes in physicians' provision of preventive cardiovascular services, focusing primarily on patients with employer sponsored health plans. STUDY DESIGN: Quasi-experimental, difference-in differences (DID) approach. METHODS: We analyzed National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey data from 2006 to 2013. Using a quasi-experimental DID approach with multivariate logistic models, we compared trends in preventive cardiovascular services delivered during physician visits among target and control populations prior to the ACA's provisions. RESULTS: The ACA was associated with an increase in use of diabetes screening (3.9% in 2006-2010 [third quarter] to 7.6% in 2010 [fourth quarter] 2013; DID, +3.5 per 100 visits; 95% CI, 1.1-5.9), tobacco use screening in adults (64.4% in 2006-2010 to 74.5% in 2010-2013; DID, +11.6 per 100 visits; 95% CI, 4.8 18.3), aspirin therapy in men (11.1% in 2006-2010 to 13.5% in 2010-2013; DID, +2.9 per 100 visits; 95% CI, 1.1-4.6), and hypertension screening (73.2% in 2006 2010 to 76.4% in 2010-2013; DID, +9.9 per 100 visits; 95% CI, 2.8-16.9). CONCLUSIONS: Provision of cardiovascular preventive care increased for some USPSTF-recommended services following enactment of the ACA, with evidence of a sex disparity in aspirin use. Other complementary policy approaches may further enhance uptake of evidence-based clinical preventive services. PMID- 29182358 TI - Diabetes care improvement in pharmacist- versus nurse-supported patient-centered medical homes. AB - OBJECTIVES: In 2009 and 2010, 17 primary care sites within 1 healthcare system became patient-centered medical homes (PCMHs), but the sites trained different personnel (pharmacists vs nurses) to improve diabetes care using self-management support (SMS). We report the challenges and successes of our efforts to: 1) assemble a new multipayer (Medicare, Medicaid, commercial) claims dataset linked to a clinical registry and 2) use the new dataset to perform comparative effectiveness research on implementation of the 2 SMS models. STUDY DESIGN: Longitudinal cohort study. METHODS: We lost permission to use private-payer data. Therefore, we used claims from Medicare fee-for-service and Medicare/Medicaid dual-eligible patients merged with chronic disease registry data. We studied 2008 to 2010, which included 1 year pre- and 1 year post the 2009 implementation time period. Outcomes were outpatient and emergency department visits, hospitalizations, care process (use of statin), and 3 intermediate outcomes (glycemic control, blood pressure [BP], and low-density lipoprotein cholesterol [LDL-C]). RESULTS: In our sample of 2826 patients, quality of care improved and utilization decreased over the 2.5 years. Both approaches improved lipid control (LDL-C decreased by an average of 4 mg/dL for pharmacy-SMS and 5.6 mg/dL for nurse-SMS) and diastolic BP (-1.5 mm Hg for pharmacy-SMS and -1.3 mm Hg for nurse SMS), whereas only the pharmacy-led approach decreased primary care visits (by 0.8 visits). The groups differed slightly on 2 measures (glycated hemoglobin, systolic BP) with respect to the trajectory of improvement over time, but performance was similar by 2.5 years. CONCLUSIONS: Diabetes care improved during PCMH implementation systemwide, supporting both nurse-led and pharmacist-led SMS models. PMID- 29182360 TI - Relationship between smell identification testing and the neuropsychological assessment of dementia in community-dwelling adults. AB - The objective of this research was to investigate the relationship of the University of Pennsylvania Smell Identification Test (UPSIT) with neuropsychological tests and identify the utility of the UPSIT in detecting cognitive impairment. This research was an archival study of neuropsychological test results obtained from 70 clients (30 male/40 female) of a community-based memory clinic. The sample had an average age of 69.7 (SD = 9.7) and education of 14.6 (SD = 2.8) years. Hypotheses were tested using correlations, receiver operating characteristic (ROC) curves, and logistic regression. The UPSIT showed significant, weak to moderate correlations with neuropsychological tests. The UPSIT raw score correlated significantly with all but one cognitive ability domain. The UPSIT T-score was significantly correlated with all cognitive domains. Obtained areas under the ROC curve (AUC) for the UPSIT ranged from .60 to .87. The AUCs of the UPSIT did not differ significantly from verbal semantic fluency tests, but the Repeatable Battery for the Assessment of Neuropsychological Status Total Scale and Delayed Memory index tended to produce larger AUCs than the UPSIT. Results from step-wise logistic regressions suggest that the UPSIT raw score provides unique information beyond its relationship to age. Olfaction relates broadly to cognitive ability and may be sensitive to early symptoms of cognitive decline. Further research is needed to explore the relationships between smell identification tests and neuropsychological assessment. PMID- 29182359 TI - Validation of a claims-based algorithm to characterize episodes of care. AB - OBJECTIVES: Although hospitals face increasing pressure from payers to improve the efficiency of healthcare delivery beyond the index hospitalization, they often lack information on postdischarge events. The Michigan Value Collaborative (MVC) developed a claims-based algorithm to provide hospitals with data on events that occur to patients beyond the hospitalization. Herein, we discuss the validation of MVC's claims-based algorithm. STUDY DESIGN: Retrospective analysis of a claims-based algorithm's ability to identify specific medical events, such as index hospitalizations, 30-day readmissions, emergency department visits, skilled nursing facility admissions, home health visits, and rehabilitation services. The claims-based events were validated using a primary review at 63 hospitals. METHODS: We selected 1830 Blue Cross Blue Shield of Michigan episodes from MVC data and asked 63 Michigan hospitals to query their medical records for the presence or absence of specific events. We then calculated agreement statistics and improved our algorithm using feedback from hospitals. RESULTS: All 63 hospitals participated in the validation process and successfully identified 99% of episodes in their medical records. The initial agreement between our algorithm and medical records was moderate for 4 postdischarge events (kappa ranging from 0.62-0.78) and poor for rehabilitation services (0.16). Much of the disagreements occurred because hospitals could not identify postdischarge events occurring outside of their hospital systems. Other disagreements occurred because of hospital coding practices. Through this analysis, the claims-based algorithm was improved to better reflect real-world coding practice. CONCLUSIONS: Our findings suggest that the MVC claims-based algorithm identifies and classifies claims with high fidelity and outperforms medical records in the identification of postdischarge events. These findings provide important insight to policy makers, payers, and hospital administrators about the value of claims-based data for the implementation of episode-based programs. PMID- 29182362 TI - Growth, nisA Gene Expression, and In Situ Activity of Novel Lactococcus lactis subsp. cremoris Costarter Culture in Commercial Hard Cheese Production. AB - This study evaluated in situ expression of the nisA gene by an indigenous, nisin A-producing (NisA+) Lactococcus lactis subsp. cremoris raw milk genotype, represented by strain M78, in traditional Greek Graviera cheeses under real factory-scale manufacturing and ripening conditions. Cheeses were produced with added a mixed thermophilic and mesophilic commercial starter culture (CSC) or with the CSC plus strain M78 (CSC+M78). Cheeses were sampled after curd cooking (day 0), fermentation of the unsalted molds for 24 h (day 1), brining (day 7), and ripening of the brined molds (14 to 15 kg each) for 30 days in a fully controlled industrial room (16.5 degrees C; 91% relative humidity; day 37). Total RNA was directly extracted from the cheese samples, and the expression of nisA gene was evaluated by real-time reverse transcription PCR (qRT-PCR). Agar overlay and well diffusion bioassays were correspondingly used for in situ detection of the M78 NisA+ colonies in the cheese agar plates and antilisterial activity in whole-cheese slurry samples, respectively. Agar overlay assays showed good growth (>8 log CFU/g of cheese) of the NisA+ strain M78 in coculture with the CSC and vice versa. The nisA expression was detected in CSC+M78 cheese samples only, with its expression levels being the highest (16-fold increase compared with those of the control gene) on day 1, followed by significant reduction on day 7 and almost negligible expression on day 37. Based on the results, certain intrinsic and mainly implicit hurdle factors appeared to reduce growth prevalence rates and decrease nisA gene expression, as well as the nisin A-mediated antilisterial activities of the NisA+ strain M78 postfermentation. To our knowledge, this is the first report on quantitative expression of the nisA gene in a Greek cooked hard cheese during commercial manufacturing and ripening conditions by using a novel, rarely isolated, indigenous NisA+ L. lactis subsp. cremoris genotype as costarter culture. PMID- 29182361 TI - Ado-trastuzumab emtansine (T-DM1) in HER2+ advanced breast cancer patients: does pretreatment with pertuzumab matter? AB - AIM: We evaluated the outcomes of patients treated with ado-trastuzumab emantasine (T-DM1) after first-line pertuzumab/trastuzumab, compared with those receiving a trastuzumab-only-based regimen. PATIENTS & METHODS: Patients who received second-line T-DM1 after pertuzumab/trastuzumab (n = 34) were compared with those who received only trastuzumab (n = 73). RESULTS: Overall response rate was 33.3% in patients with prior pertuzumab and 57.1% in the remaining subjects. Disease control rate was 47 and 43%, respectively, and the clinical benefit rate was 43.3 and 71.1%, respectively. Median progression-free survival was 5.0 and 11.0 months, respectively (hazard ratio: 2.02; 95% CI: 1.14-3.58; p = 0.01). CONCLUSION: Patients treated with T-DM1 who previously received pertuzumab present poorer clinical outcomes compared with those receiving a trastuzumab-only based regimen in the first-line setting. PMID- 29182363 TI - Interdisciplinarity and Adapted Physical Activity. AB - The purpose of the paper was to draw lessons for the field of adapted physical activity from the interrelated literatures on interdisciplinarity, creativity, and team research. In each of these literatures, strategies have been identified that have been found to be useful by previous researchers. Lack of familiarity with these strategies can result in unsuccessful research projects or in the devotion of scarce resources to the reinvention of such strategies. The first section in the paper in particular addresses questions that arose at the 2016 North American Federation of Adapted Physical Activity symposium in Edmonton, Alberta. PMID- 29182364 TI - How Journalists Characterize Health Inequalities and Redefine Solutions for Native American Audiences. AB - Many Native American communities experience severe health inequalities, including shorter average lifespan and higher rates of chronic illnesses. Journalism that serves Native Americans is a promising channel for heath communication, but only if scholars first understand the particular cultural contexts of indigenous communities. This research contributes to that goal by investigating how journalists serving Native American communities characterize health and the issues they identify with covering determinants of health. In in-depth interviews (N = 24), journalists contrasted how they cover health issues as embedded in cultural context with shallow, more negative coverage by non-Native media organizations. Interviews also revealed a tension between "medical" and "cultural" models of health, contributing to the oversaturation of certain issues, like diabetes, while other health topics are underrepresented. The journalists also expressed how social determinants and histories of oppression shape health inequalities, illuminating the roles of historical trauma and the destruction of indigenous health beliefs and behaviors. Failure to recognize these issues could stymie efforts to communicate about health issues facing Native American audiences. PMID- 29182365 TI - Career Development and Learning Pathways of Paralympic Coaches With a Disability. AB - The purpose of this study was to gain an understanding of the career development and learning pathways of Paralympic head coaches who previously competed as Paralympic athletes. Each coach participated in a semistructured interview. A thematic analysis of the data revealed three higher order themes, which were called becoming a coach, learning to coach, and lifelong learning and teaching. Across these themes, participants discussed interactions with other coaches and athletes with a disability, learning from mentors and coaching clinics, as well as limited formal educational opportunities they experienced transitioning from athlete to head coach. The findings revealed that they acquired most of their knowledge from a combination of knowledge gained as athletes and informal sources, including trial and error. They also stressed the need for enhanced recruiting of parasport coaches and parasport coach education opportunities that would enhance programs for athletes with physical disabilities, from grassroots to Paralympic levels. PMID- 29182367 TI - Associations between Poor Sleep Quality, Obesity, and the Anthropometric Measurements of Women in Turkey. AB - Recent studies have shown that poor sleep quality is significantly associated with obesity. The aim of this study is to examine the association of sleep quality with obesity and specific anthropometric measurements. A total of 105 women aged 20-55 years with no chronic diseases participated in this study. They filled out the Pittsburgh Sleep Quality Index (PSQI), their anthropometric measurements were taken, and their dietary data were collected with a food frequency questionnaire (FFQ). There was no significant relationship between sleep quality and BMI, waist circumference, triceps skinfold thicknesses, body fat ratio (%), and body fat mass (p > .05), but high bread consumption was significantly associated with poor sleep quality (p < .05). The women with poor sleep quality consumed significantly more bread, but not other foods, than the women with good sleep quality. Sleep quality can thus be related to eating habits. PMID- 29182368 TI - Fine needle aspiration biopsy of thyroid nodule smaller than 1.0 cm: accuracy of TIRADS classification system in more than 1000 nodules. AB - OBJECTIVE: To identify whether or not the same ultrasound features can be applied and should be considered to support the decision as to which subcentimeter nodules should be biopsied with fine needle aspiration (FNAB). METHODS: Single institution, IRB approved, retrospective study conducted from 2008 to 2016 that evaluated 1094 thyroid nodules smaller than 1.0 cm that were classified according to TIRADS and submitted for FNAB. RESULTS: The value of FNAB of thyroid nodules smaller than 1.0 cm were assessed and correlated with the sonographic criteria by comparing the obtained results with the cytological findings in 1094 thyroid nodules. In the analysis considering all nodules, the proportion of malignancies among nodules with TIRADS 2 is 0.91% and for TIRADS 3 is 2.87%. Among those classified as 4A, 12.26%; with 4B classification, 34.43%; with 4C classification, 66.6%; and among those with 5 classifications, 85.7%. CONCLUSION: In conclusion, the TIRADS classification system, based on the sonographic features reported herein, may help detect which nodules should be investigated for potential malignancies. Advances in knowledge: Few reports compare the efficacy of ultrasound-FNAB for thyroid nodules smaller than 1.0 cm in diameter. The findings of malignancy in this subgroup of nodules may help in the clinical follow-up of which patients should be submitted to an early imaging evaluation or intervention. PMID- 29182369 TI - Infertility, Adoption, and Family Formation in Indonesia. AB - When combined, primary and secondary infertility affects up to 21 percent of Indonesian couples. Based on ethnographic fieldwork with married heterosexual couples, I explore how intra-family adoption represents a culturally and religiously acceptable pathway to family formation for couples without access to assisted reproductive technologies. I examine how kinship is central to the negotiation of adoption, and to maintaining ethnic and religious continuity within adoptive families. I reveal how adoption can enable infertile women and birth mothers to achieve or escape the dominant expectations of heteronormativity, and discuss intra-family adoption by infertile couples in relation to reproductive stratification and leveling. PMID- 29182370 TI - Communicating Inequalities to Enhance Support for Obesity-Prevention Policies: The Role of Social Comparisons, Age Frames, and Emotion. AB - With certain populations in the United States at higher risk for obesity than other populations, public health advocates have attempted to draw attention to these inequalities to galvanize support for obesity-mitigation policies. Yet research comparing different messages about social inequalities indicates that not all social comparisons are persuasive. Drawing on Weiner's (1986) theory of perceived responsibility and social motivation, I experimentally tested promising message frames about obesity disparities. Participants (N = 653) read one of six messages following a 3 (social comparison frame: geographic vs. racial vs. no comparison) * 2 (age frame: child vs. adult) between-subjects design. Unexpectedly, geographic frames (rural/urban) indirectly decreased policy support relative to the control frame by way of increased counterarguing. Compared to adult frames about obesity inequalities, childhood frames evoked more sympathy and less internal attribution, which in turn positively predicted support for obesity-prevention policies. Practical and theoretical implications of these findings are discussed. PMID- 29182372 TI - Modulation of working memory load distinguishes individuals with and without balance impairments following mild traumatic brain injury. AB - OBJECTIVES: Balance and gait deficits can persist after mild traumatic brain injury (TBI), yet an understanding of the underlying neural mechanism remains limited. The purpose of this study was to investigate differences in attention network modulation in patients with and without balance impairments 2-8 weeks following mild TBI. METHODS: Using functional magnetic resonance imaging, we compared activity and functional connectivity of cognitive brain regions of the default mode, central-executive and salience networks during a 2-back working memory task in participants with mild TBI and balance impairments (n = 7, age 47 +/- 15 years) or no balance impairments (n = 7, age 47 +/- 15 years). RESULTS: We first identified greater activation in the lateral occipital cortex in the balance impaired group. Second, we observed stronger connectivity of left pre supplementary motor cortex in the balance impaired group during the working memory task, which was related to decreased activation of regions within the salience and central executive networks and greater suppression of the default mode network. CONCLUSIONS: Results suggest a link between impaired balance and modulation of cognitive resources in patients in mTBI. Findings also highlight the potential importance of moving beyond traditional balance assessments towards an integrative assessment of cognition and balance in this population. PMID- 29182371 TI - Decrease in scale invariance of activity fluctuations with aging and in patients with suprasellar tumors. AB - Motor activity in healthy young humans displays intrinsic fluctuations that are scale-invariant over a wide range of time scales (from minutes to hours). Human postmortem and animal lesion studies showed that the intact function of the suprachiasmatic nucleus (SCN) is required to maintain such scale-invariant patterns. We therefore hypothesized that scale invariance is degraded in patients treated for suprasellar tumors that compress the SCN. To test the hypothesis, we investigated 68 patients with nonfunctioning pituitary macroadenoma and 22 patients with craniopharyngioma, as well as 72 age-matched healthy controls (age range 21.0-70.6 years). Spontaneous wrist locomotor activity was measured for 7 days with actigraphy, and detrended fluctuation analysis was applied to assess correlations over a range of time scales from minutes to 24 h. For all the subjects, complex scale-invariant correlations were only present for time scales smaller than 1.5 h, and became more random at time scales 1.5-10 h. Patients with suprasellar tumors showed a larger decrease in correlations at 1.5-10 h as compared to healthy controls. Within healthy subject, gender and age >33 year were associated with attenuated scale invariance. Conversely, activity patterns at time scales between 10 and 24 h were significantly more regular than all other time scales, and this was mostly associated with age. In conclusion, scale invariance is degraded in healthy subjects at the ages of >33 year as characterized by attenuation of correlations at time scales 1.5-10 h. In addition, scale invariance was more degraded in patients with suprasellar tumors as compared to healthy subjects. PMID- 29182373 TI - Texture analysis of 18F-FDG PET/CT for grading thymic epithelial tumours: usefulness of combining SUV and texture parameters. AB - OBJECTIVE: To retrospectively investigate the standardized uptake value (SUV) related and heterogeneous texture parameters individually and in combination for differentiating between low- and high-risk 18Fluorone-fludeoxyglucose (18F-FDG) avid thymic epithelial tumours (TETs) with positron emission tomography (PET)/CT. METHODS: SUV-related and 6 texture parameters (entropy, homogeneity, dissimilarity, intensity variability, size-zone variability and zone percentage) were compared between 11 low-risk and 23 high-risk TETs (metabolic tumour volume >10.0 cm3 and SUV >=2.5). Diagnostic performance was evaluated by receiver operating characteristic analysis. The diagnostic value of combining SUV and texture parameters was examined by a scoring system. RESULTS: High-risk TETs were significantly higher in SUVmax (p = 0.022), entropy (p = 0.038), intensity variability (p = 0.041) and size-zone variability (p = 0.045) than low-risk TETs. Diagnostic accuracies of these 4 parameters, dissimilarity and zone percentage which also showed significance in receiver operating characteristic analysis ranged between 64.7 and 73.5% without significant differences in AUC (range; 0.71 to 0.75) (p >= 0.05 each). Each parameter was scored as 0 (negative for high risk) or 1 (positive for high-risk) according to each threshold criterion, then scores were summed [0 or 1 for low-risk TETs (median; 1); >=2 for high-risk TETs (median; 4)]. The sensitivity, specificity and accuracy of detecting high-risk TETs were 100, 81.8 and 94.1%, respectively, with an AUC of 0.99. CONCLUSION: The diagnostic performances of individual SUVmax and texture parameters were relatively low. However, combining these parameters can significantly increase diagnostic performance when differentiating between relatively large low- and high-risk 18F-FDG-avid TETs. Advances in knowledge: Combined use of SUVmax and texture parameters can significantly increase the diagnostic performance when differentiating between low- and high-risk TETs. PMID- 29182374 TI - Lack of association of mirSNP rs11174811 in AVPR1A gene with arterial blood pressure and hypertension in South Indian population. AB - Epigenetic regulation of arterial blood pressure mediated through mirSNPs in renin-angiotensin aldosterone system (RAAS) genes is a less explored hypothesis. Recently, the mirSNP rs11174811 in the 3'UTR of the AVPR1A gene was associated with higher arterial blood pressure in a large study population from the Study of Myocardial Infarctions Leiden (SMILE). The aim of the present study was to replicate the association of mirSNP rs11174811 with blood pressure outcomes and hypertension in a south Indian population. Four hundred and fifteen hypertensive cases and 416 normotensive controls were genotyped using a 5' nuclease allelic discrimination assay. Logistic regression was used to test the association of mirSNP rs11174811 with the hypertension phenotype. Censored normal regression was used to test the association of the polymorphism with continuous blood pressure outcomes such as systolic and diastolic blood pressure. The mirSNP rs11174811 did not show any significant association with hypertension. The adjusted odds ratio was 1.02, with 95% CI of 0.72 to 1.45 (p = 0.909). The mean systolic and diastolic blood pressure values were not significantly different across the three genotypic groups, between hypertensives and normotensives, or when stratified by gender. Despite having a similar minor allele frequency (MAF) of 14.5% compared with the SMILE cohort, our results did not support an association of the mirSNP rs11174811 with the hypertension phenotype or with continuous blood pressure outcomes in the south Indian population. PMID- 29182375 TI - Multilevel Examination of Job Satisfaction and Career Intentions of Collegiate Athletic Trainers: A Quantitative Approach. AB - CONTEXT: Recent employment data from collegiate athletic training settings have demonstrated departure trends among men and women. These trends have been hypothesized to be related to work-life balance. However, work-life balance is only 1 aspect of a myriad of factors. Due to the complex nature of the work-life interface, a multilevel examination is needed to better understand the precipitators of departure. OBJECTIVE: To quantitatively examine factors that may influence collegiate athletic trainers' (ATs') job satisfaction and career intentions via a multilevel examination of the work-life interface. DESIGN: Cross-sectional study. SETTING: Web-based questionnaire. PATIENTS OR OTHER PARTICIPANTS: Athletic trainers employed in National Collegiate Athletic Association Division I, II, or III or National Association of Intercollegiate Athletics colleges or universities (N = 299: 56.5% female, 43.5% male). The average age of participants was 33.6 +/- 8.3 years, and their average experience was 10.3 +/- 7.6 years. DATA COLLECTION AND ANALYSIS: Participants responded to an online questionnaire consisting of demographic questions, 9 Likert-scale surveys, and open-ended questions. Job-satisfaction Scores (JSSs) and intention to-leave scores (ITLSs) served as the dependent variables and factors from individual, organizational, and sociocultural levels were the independent variables. Hierarchical regression analysis was run to determine the predictability of factors. RESULTS: No sex differences in ITLS or JSS were found in our sample. Independent variables explained 68.5% of the variance in JSS and 28.8% of the variance in ITLS. Additions of factor levels increased the percentage of explained variance in both scores. CONCLUSIONS: A combination of individual-, organizational-, and sociocultural-level factors was able to best predict JSS and ITLS among collegiate ATs. PMID- 29182376 TI - Perceptions of Work-Life Balance Practices Offered in the Collegiate Practice Setting. AB - CONTEXT: Organizational factors have been identified as barriers to finding work-life balance (WLB) in athletic training. Despite the existence of organizational policies to address WLB, little is known about athletic trainers' (ATs') awareness of these policies that could assist them. OBJECTIVE: To better understand the perceptions of ATs regarding the workplace practices available to them, which may help them achieve WLB. DESIGN: Phenomenologic study. SETTING: Collegiate practice setting. PATIENTS OR OTHER PARTICIPANTS: Twenty-one ATs (women = 10, men = 11) employed at the collegiate level (National Collegiate Athletic Association Division I = 12, Division II = 5, Division III = 4) volunteered for our study. The average age of the participants was 33 +/- 9 years. Saturation of the data was met at n = 21. DATA COLLECTION AND ANALYSIS: Participants completed an in-depth, 1-on-1 phone interview, which was then transcribed verbatim. Data were analyzed using a phenomenologic approach. Credibility was determined by member checks, peer review, and researcher triangulation. RESULTS: Our analyses revealed that participants (1) had a limited awareness of formal policies that were offered within their university or collegiate infrastructure; (2) used informal policies to manage their personal, family, and work obligations; and (3) thought that more formal policies, such as adherence to adequate staffing patterns and work schedules, could help establish WLB within collegiate athletic training settings. CONCLUSIONS: Informal workplace policies were more commonly used by our participants and were viewed as a means of creating a supportive atmosphere. Administrators and supervisors should consider creating or endorsing more formal policies specific to the demands of an AT in the collegiate setting to help with WLB.

PMID- 29182379 TI - Prevalence and association of oral candidiasis with dysphagia in individuals with acquired brain injury. AB - OBJECTIVE: To describe the prevalence of oral candidiasis (OC) in individuals with acquired brain injury (ABI) and to evaluate the association of OC with improvement in dysphagia. DESIGN: Longitudinal observational study. METHODS: Individuals with ABI admitted to rehabilitation were recruited over a one-year period (n = 206 (59% with dysphagia)). OC-data were collected by clinical examinations and verified by cultivation/microscopy in every 3 weeks during first 10 weeks of admission. Dysphagia improvement was defined by: 1) first positive change in food consistency, 2) initiation of at least soft food consistency. Individuals with/without OC were compared using multivariable Cox proportional hazards regression. RESULTS: The overall OC prevalence in all individuals, in individuals with dysphagia and in individuals not treated with antifungal agents were 32.5%, 43.4% and 29.7%, respectively. The OC prevalence was 24.8% at one week after admission and reduced to 10.1% ten weeks after admission. Adjusted hazard ratios for improvement in dysphagia were 0.64-0.77 in OC compared to without OC, though not statistically significant. CONCLUSION: Prevalence of OC was high at admission but reduced during rehabilitation. Though non-significant, the negative trend between OC and improvement in dysphagia suggest that OC may delay rehabilitation of dysphagia. PMID- 29182380 TI - The Relationship between Emotional and Esteem Social Support Messages and Health. AB - The purpose of this investigation is to determine the relative contribution of five types of social support to improved patient health. This analysis suggests that emotional and esteem social support messages are associated with improved patient health as measured by a decrease in average blood glucose levels among diabetic patients. In addition, when two system feature variables, two system use variables, two measures of learning, one measure of self-efficacy, and one measure of affect toward their HCP were added to the baseline model, a third significant factor emerged. Perceptions about learning about diabetes from reading the digital messages sent by their HCP also predicted improved patient health. Cognitive-Emotional Theory of Esteem Support Messages suggests a combination of esteem social support and emotional social support messages enhanced our ability to predict improved patient health by change in patient hemoglobin A1c (HbA1c) scores. While a nonrandomized prospective study, this investigation provides support for the notion that provider-patient interaction is related to improved patient health and that both emotional and esteem social support messages play a role in that process. Finally, the study suggests some types of social support are and other types are not associated with improved patient health; this is consistent with the optimal matching hypothesis. PMID- 29182378 TI - Early changes in cerebral autoregulation among youth hospitalized after sports related traumatic brain injury. AB - OBJECTIVE: To examine early cerebral haemodynamic changes among youth hospitalized with sports-related traumatic brain injury (TBI). STUDY DESIGN: Youth 0-18 years admitted to a level one trauma centre with sports-related TBI were enrolled. Daily measures included clinical symptoms and Glasgow Coma Scale (GCS) score. Using Transcranial Doppler (TCD) ultrasonography and tilt testing, we measured middle cerebral artery flow velocity (Vmca) and cerebral autoregulation index (ARI). RESULTS: Six previously healthy males age 14 (IQR 12 16) years with headache and abnormal head CT were admitted with median admission GCS 15. Six patients underwent 12 TCD examinations between hospital days 0-9. Low Vmca occurred in 3/6 patients and on the side of TBI, whereas high Vmca occurred in 2/6 patients. Five patients had at least one measurement of impaired and five patients had absent cerebral autoregulation of at least one hemisphere; all these five patients had GCS 15 and headache during TCD examinations. Three patients were discharged with absent cerebral autoregulation. Five (83%) patients were discharged to home and one patient was discharged to a rehabilitation facility. CONCLUSION: Headache, abnormal Vmca and impaired cerebral autoregulation occur after sports-related TBI, despite normal GCS. Headache may signal underlying neurovascular abnormality in sports-related TBI. PMID- 29182381 TI - A validation of the Polish version of the Coma Recovery Scale-Revised (CRSR). AB - PRIMARY OBJECTIVE: The aim of this study was to determine the validity of the Polish version of the Coma Recovery Scale-Revised (CRS-R). METHODS AND DESIGN: Two trained raters, A and B, administered CRS-R on a group of 20 patients with severe brain injury (median age +/- SD, 38.0 +/- 14.39 years). Both rater A and rater B completed their assessment on day 1, and rater A repeated their assessment on day 2. Inter-rater and test-retest reliability were evaluated with an intra-class correlation coefficient and Spearman rank correlation. Internal consistency was estimated with Cronbach's alpha. Agreement in diagnostic impression was determined using Cohen's kappa. RESULTS: Inter-rater reliability for CRS-R total scores and test-retest reliability was excellent: (rho = 0.76, p < 0.001) and (rho = 0.92, p < 0.001), respectively. Inter-rater diagnostic agreement was good (kappa = 0.72, p < 0.001). Inter-rater reliability for subscales was fair to excellent. Internal consistency was excellent (Cronbach's alpha = 0.85). CONCLUSION: The Polish version of CRS-R can be administered reliably by trained raters and can successfully differentiate between vegetative state (VS), minimally conscious (MCS), and patients emerging from a minimally conscious state (EMCS). PMID- 29182382 TI - Features of the daily rhythms of blood melatonin and glucose in goats during different natural photoperiod. AB - The scope of the present study was to explore the features of the daily rhythms of plasma melatonin and blood glucose in goats during different natural photoperiod imposed by the four seasons. Five Sarda breed pluriparus female goats, 2 years old, with a mean body weight 40.5 +/- 2.3 kg, lead to a natural pasture, were cannulated the day before the start of the study for sample collection performed during spring and autumn equinoxes, and winter and summer solstices for a 48-h period. On blood samples, melatonin and glucose concentrations were assessed. Our results indicate a daily rhythm of both parameters studied which characteristics were influenced by the different photoperiod due to season. During the experimental period, the two parameters showed a negative correlation, despite the onset of melatonin concentration was linked to the sunset, whereas the onset and offset of glucose were not linked to the photoperiod. In conclusion, we can claim that the two parameters are driven by different entrainable systems, but further studies are necessary to establish their correlation.

PMID- 29182385 TI - Magnetic resonance imaging measurements of organs within the coelomic cavity of red-eared sliders (Trachemys scripta elegans), yellow-bellied sliders (Trachemys scripta scripta), Coastal plain cooters (Pseudemys concinna floridana), and hieroglyphic river cooters (Pseudemys concinna hieroglyphica). AB - OBJECTIVE To determine anatomic reference points for 4 turtle species and to evaluate data on relative anatomic dimensions, signal intensities (SIs), and position of selected organs within the coelomic cavity by use of MRI. ANIMALS 3 turtle cadavers (1 red-eared slider [Trachemys scripta elegans], 1 yellow-bellied slider [Trachemys scripta scripta], and 1 Coastal plain cooter [Pseudemys concinna floridana]) and 63 live adult turtles (30 red-eared sliders, 20 yellow bellied sliders, 5 Coastal plain cooters, and 8 hieroglyphic river cooters [Pseudemys concinna hieroglyphica]). PROCEDURES MRI and necropsy were performed on the 3 turtle cadavers. Physical examination, hematologic evaluation, and whole body radiography were performed on the 63 live turtles. Turtles were sedated, and MRI in transverse, sagittal, and dorsal planes was used to measure organ dimensions, position within the coelomic cavity, and SIs. Body positioning after sedation was standardized with the head, neck, limbs, and tail positioned in maximum extension. RESULTS Measurements of the heart, liver, gallbladder, and kidneys in sagittal, transverse, and dorsal planes; relative position of those organs within the coelom; and SIs of the kidneys and liver were obtained with MRI and provided anatomic data for these 4 turtle species. CONCLUSIONS AND CLINICAL RELEVANCE MRI was a valuable tool for determining the position, dimensions, and SIs of selected organs. Measurement of organs in freshwater chelonians was achievable with MRI. Further studies are needed to establish reference values for anatomic structures in turtles. Results reported here may serve as guidelines and aid in clinical interpretation of MRI images for these 4 species. PMID- 29182384 TI - Efficacy of a rectal spacer with prostate SABR-first UK experience. AB - OBJECTIVE: This study assessed the use of implanted hydrogel rectal spacers for stereotactic ablative radiotherapy-volumetric modulated arc therapy (SABR-VMAT) patients, investigating practicality, dosimetric impact, normal tissue complication probability (NTCP) and early toxicity. METHODS: Data from the first 6 patients treated within a prostate SABR and rectal spacer trial were examined to determine spacer insertion tolerability, resultant changes in treatment planning and dosimetry and early toxicity effects. CT scans acquired prior to spacer insertion were used to generate SABR plans which were compared to post insertion plans. Plans were evaluated for target coverage, conformity, and organs at risk doses with NTCPs also determined from resultant dose fluences. Early toxicity data were also collected. RESULTS: All patients had successful spacer insertion under local anaesthetic with maximal Grade 1 toxicity. All plans were highly conformal, with no significant differences in clinical target volume dose coverage between pre- and post-spacer plans. Substantial improvements in rectal dose metrics were observed in post-spacer plans, e.g. rectal volume receiving 36 Gy reduced by >=42% for all patients. Median NTCP for Grade 2 + rectal bleeding significantly decreased from 4.9 to 0.8% with the use of a rectal spacer (p = 0.031). To date, two episodes of acute Grade 1 proctitis have been reported following treatment. CONCLUSION: The spacer resulted in clinically and statistically significant reduction in rectal doses for all patients. Advances in knowledge: This is one of the first studies to investigate the efficacy of a hydrogel spacer in prostate SABR treatments. Observed dose sparing of the rectum is predicted to result in meaningful clinical benefit. PMID- 29182386 TI - In vivo evaluation of effects of sedation on results of acoustoelastography of the superficial digital flexor tendons in clinically normal horses. AB - OBJECTIVE To assess the effects of sedation on results of acoustoelastography of the superficial digital flexor tendons (SDFTs) in clinically normal horses. ANIMALS 27 clinically normal horses. PROCEDURES For each horse, the pathology index (PI) for the SDFT of each thoracic limb was determined by use of acoustoelastography at 4 locations (5, 10, 15, and 20 cm distal to the accessory carpal bone). Horses were evaluated before and after they were sedated with a combination of detomidine hydrochloride (0.01 mg/kg, IV) and butorphanol tartrate (0.01 mg/kg, IV). A repeated-measures ANOVA was used for statistical analysis. RESULTS Overall, the PI was lower after sedation than before sedation. In addition, the PI was lower at more distal locations than at more proximal locations. There was not a significant effect of limb (left or right). Differences among individual horses accounted for the largest variance effect. CONCLUSIONS AND CLINICAL RELEVANCE Sedation with detomidine and butorphanol facilitated acoustoelastography; however, it decreased the SDFT PI in clinically normal horses and should be used consistently in prospective studies. Variance associated with each individual horse in the sample population had the greatest effect on the PI. PMID- 29182388 TI - Pharmacokinetics of ampicillin-sulbactam in serum and synovial fluid samples following regional intravenous perfusion in the distal portion of a hind limb of adult cattle. AB - OBJECTIVE To describe concentration-over-time data for ampicillin and sulbactam in the digital and systemic circulations and synovial fluid (SYN) of cattle following a single injection of ampicillin-sulbactam as a regional IV perfusion (RIVP). ANIMALS 6 healthy adult nonlactating Jersey-crossbred cows. PROCEDURES The right hind limb of each cow was aseptically prepared. A tourniquet was applied around the midmetatarsal region, and 1.0 g of ampicillin with 0.5 g of sulbactam in a combined formulation was administered as an RIVP into the dorsal common digital vein (DCDV). Blood samples from the DCDV and jugular vein and SYN samples from the metatarsophalangeal joint of the prepared limb were collected immediately before and at predetermined times for 24 hours after RIVP. One blood sample was obtained from the abaxial proper plantar vein of the lateral digit of the prepared limb 0.25 hours after RIVP. Serum and SYN ampicillin and sulbactam concentrations were determined by high-performance liquid chromatography. RESULTS Mean +/- SD maximum concentration of ampicillin in SYN and serum obtained from the abaxial proper plantar and jugular veins was 1,995 +/- 1,011 MUg/mL, 5,422 +/ 1,953 MUg/mL, and 2.5 +/- 1.6 MUg/mL, respectively. Corresponding serum and SYN concentrations of sulbactam were lower but followed the same pattern over time as those for ampicillin. Synovial fluid ampicillin concentration remained above 8 MUg/mL for a mean time of 18.9 hours. CONCLUSIONS AND CLINICAL RELEVANCE Potentially therapeutic concentrations of ampicillin were achieved in regional serum and SYN samples; SYN concentrations remained at potentially therapeutic values for > 12 hours following RIVP of 1.5 g of ampicillin-sulbactam in the hind limb of healthy cows. PMID- 29182389 TI - Effect of a high-fat-high-cholesterol diet on gallbladder bile acid composition and gallbladder motility in dogs. AB - OBJCTIVE To investigate the effects of dietary lipid overload on bile acid metabolism and gallbladder motility in healthy dogs. ANIMALS 7 healthy Beagles. PROCEDURES In a crossover study, dogs were fed a high-fat-high-cholesterol diet (HFCD) or a low-fat diet (LFD) for a period of 2 weeks. After a 4-month washout period, dogs were fed the other diet for 2 weeks. Before and at the end of each feeding period, the concentrations of each of the gallbladder bile acids, cholecystokinin (CCK)-induced gallbladder motility, and bile acid metabolism related hepatic gene expression were examined in all dogs. RESULTS The HFCD significantly increased plasma total cholesterol concentrations. The HFCD also increased the concentration of taurochenodeoxycholic acid and decreased the concentration of taurocholic acid in bile and reduced gallbladder contractility, whereas the LFD significantly decreased the concentration of taurodeoxycholic acid in bile. Gene expression analysis revealed significant elevation of cholesterol 7alpha-hydroxylase mRNA expression after feeding the HFCD for 2 weeks, but the expression of other genes was unchanged. CONCLUSIONS AND CLINICAL RELEVANCE Feeding the HFCD and LFD for 2 weeks induced changes in gallbladder bile acid composition and gallbladder motility in dogs. In particular, feeding the HFCD caused an increase in plasma total cholesterol concentration, an increase of hydrophobic bile acid concentration in bile, and a decrease in gallbladder sensitivity to CCK. These results suggested that similar bile acid compositional changes and gallbladder hypomotility might be evident in dogs with hyperlipidemia. PMID- 29182390 TI - In vitro effect of blood cell counts on multiple-electrode impedance aggregometry in dogs. AB - OBJECTIVE To assess the effect of decreased platelet and WBC counts on platelet aggregation as measured by a multiple-electrode impedance aggregometer in dogs. ANIMALS 24 healthy dogs. PROCEDURES From each dog, 9 mL of blood was collected into a 10-mL syringe that contained 1 mL of 4% sodium citrate solution to yield a 10-mL sample with a 1:9 citrate-to-blood ratio. Each sample was then divided into unmanipulated and manipulated aliquots with progressively depleted buffy-coat fractions such that 2 to 3 blood samples were evaluated per dog. The Hct for manipulated aliquots was adjusted with autologous plasma so that it was within 2% of the Hct for the unmanipulated aliquot for each dog. All samples were analyzed in duplicate with a multiple-electrode impedance aggregometer following the addition of ADP as a platelet agonist. The respective effects of platelet count, plateletcrit, Hct, and WBC count on platelet aggregation area under the curve (AUC), aggregation, and velocity were analyzed with linear mixed models. RESULTS WBC count was positively associated with platelet AUC, aggregation, and velocity; blood samples with leukopenia had a lower AUC, aggregation, and velocity than samples with WBC counts within the reference range. Platelet count, plateletcrit, and Hct did not have an independent effect on AUC, aggregation, or velocity. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that WBC count was positively associated with platelet aggregation when ADP was used to activate canine blood samples for impedance aggregometry. That finding may be clinically relevant and needs to be confirmed by in vivo studies. PMID- 29182391 TI - Effect of meloxicam administration on movement, feeding, and drinking behaviors of transported and nontransported cattle. AB - OBJECTIVE To evaluate the effects of meloxicam on movement, feeding, and drinking behaviors of transported and nontransported cattle. ANIMALS 100 crossbred beef steers. PROCEDURES During experiment 1 of a 2-experiment study, calves from a livestock auction received meloxicam (1 mg/kg, PO; n = 50) or a lactose placebo (1 capsule/calf; 50; control), then calves were transported approximately 1,000 km overnight to a feedlot, where they were instrumented with a real-time location monitoring ear tag, placed in randomly assigned pens (n = 5 pens/treatment), and monitored for 21 days. During experiment 2, calves in pens were administered the treatment opposite that of experiment 1, returned to their pens without undergoing transportation, and monitored for another 21 days. For each experiment, mean daily distance traveled and percentage time spent near feed (PNF) and water (PNW) were calculated on a pen basis and compared between treatments. RESULTS During experiment 1, mean daily distance traveled, PNF, and PNW did not differ significantly between meloxicam-treated and control calves; however, all 3 behaviors varied significantly by day. During experiment 2, although mean distance traveled was significantly associated with the interaction between day and treatment, it did not differ significantly between meloxicam treated and control calves within any specific day. Mean PNF and PNW were significantly associated with day only, although no pattern in that effect was evident. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that a single dose of meloxicam prior to transportation did not significantly affect the behaviors of transported and nontransported calves. PMID- 29182392 TI - Effect of oral administration of meloxicam prior to transport on inflammatory mediators and leukoctye function of cattle at feedlot arrival. AB - OBJECTIVE To investigate the effects of meloxicam administration before long distance transport on inflammatory mediators and leukocyte function of cattle at feedlot arrival. ANIMALS 60 healthy yearling beef steers. PROCEDURES Single source steers were assigned to a transported (n = 40) or nontransported (20) group. Then, half of the steers within each group were assigned to receive meloxicam (1 mg/kg, PO) or a lactose placebo (1 bolus/steer, PO). All steers were transported approximately 1,300 km overnight to a feedlot; however, the nontransported group was moved before treatment (meloxicam or placebo) administration and allowed a 17-day acclimation period, whereas the transported group was moved immediately after treatment administration on day -1. Blood samples for measurement of inflammatory mediators and leukocyte function were collected from all steers on days -1, 0, and 3. RESULTS For steers that received meloxicam, mean plasma meloxicam concentration for the transported group was significantly greater than that for the nontransported group on day 0. For steers that received the placebo, mean haptoglobin-matrix metalloproteinase-9 complex for the transported group was significantly greater than that for the nontransported group on day 0. Mean haptoglobin concentration, neutrophil L selectin intensity, and polymorphonuclear leukocyte count for the transported group were significantly greater than those for the nontransported group. Mean substance P concentration for nontransported steers that received meloxicam was significantly lower than that for the other 3 treatment groups. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated meloxicam administration to healthy steers immediately before long-distance transport did not significantly mitigate the effects of transport-induced stress on leukocyte function or inflammatory markers. PMID- 29182393 TI - Analysis of the association between density of Helicobacter spp and gastric lesions in dogs. AB - OBJECTIVE To evaluate the correlation between the density of native gastric Helicobacter spp and the presence of gastric lesions in dogs. ANIMALS 80 dogs of various breeds, sexes, and ages. PROCEDURES Gastroscopic and histologic examinations were performed for all dogs. Helicobacter spp were detected by combining evaluation of urease activity and results of bacteriologic culture, microscopic observation, and a 16S rRNA PCR assay. The density of Helicobacter like organisms was evaluated with light microscopy by use of Warthin-Starry modified stain. Correlations were evaluated by use of the Spearman correlation analysis. RESULTS Gastritis was found in 55 of 80 dogs and classified as mild (n = 31), moderate (16), or severe (8). Of these 55 dogs, only 8 had clinical signs. Histologic examination revealed some degree of lymphocytic-plasmacytic infiltrate, mild eosinophilia, and neutrophilic inflammation in the lamina propria. Seventy-six dogs had positive results for Helicobacter spp. Helicobacter pylori DNA was not detected. Low density and homogeneous distribution of Helicobacter spp were observed in all gastric zones. CONCLUSIONS AND CLINICAL RELEVANCE A significant correlation between density of Helicobacter spp and gastroscopic or histologic lesions was not detected. These findings supported the contention that there is no correlation between general Helicobacter spp density or numbers and gastritis in dogs. PMID- 29182394 TI - Effects of intravenous administration of lidocaine and buprenorphine on gastrointestinal tract motility and signs of pain in New Zealand White rabbits after ovariohysterectomy. AB - OBJECTIVE To compare analgesic and gastrointestinal effects of lidocaine and buprenorphine administered to rabbits undergoing ovariohysterectomy. ANIMALS Fourteen 12-month-old female New Zealand White rabbits. PROCEDURES Rabbits were assigned to 2 treatment groups (7 rabbits/group). One group received buprenorphine (0.06 mg/kg, IV, q 8 h for 2 days), and the other received lidocaine (continuous rate infusion [CRI] at 100 MUg/kg/min for 2 days). Variables, including food and water consumption, fecal output, glucose and cortisol concentrations, and behaviors while in exercise pens, were recorded. RESULTS Rabbits receiving a lidocaine CRI had significantly higher gastrointestinal motility, food intake, and fecal output and significantly lower glucose concentrations, compared with results for rabbits receiving buprenorphine. Rabbits receiving lidocaine also had a higher number of normal behaviors (eg, sprawling, traveling, and frolicking) after surgery, compared with behaviors such as crouching and sitting that were seen more commonly in rabbits receiving buprenorphine. Both groups had significant weight loss after surgery. Pain scores did not differ significantly between treatment groups. Significant decreases in heart rate and respiratory rate were observed on the day of surgery, compared with values before and after surgery. Rabbits in the lidocaine group had significantly overall lower heart rates than did rabbits in the buprenorphine group. CONCLUSIONS AND CLINICAL RELEVANCE A CRI of lidocaine to rabbits provided better postoperative outcomes with respect to fecal output, food intake, and glucose concentrations. Thus, lidocaine appeared to be a suitable alternative to buprenorphine for alleviating postoperative pain with minimal risk of anorexia and gastrointestinal ileus. PMID- 29182395 TI - Evaluation of the dens-to-axis length ratio and dens angle in toy-breed dogs with and without atlantoaxial instability and in healthy Beagles. AB - OBJECTIVE To evaluate and compare morphological characteristics of the dens in atlantoaxial instability (AAI)-predisposed toy-breed dogs (TBDs) with and without AAI and non-AAI-predisposed healthy Beagles. ANIMALS 80 AAI-affected and 40 nonaffected TBDs and 40 Beagles. PROCEDURES Each dog underwent CT examination of the cervical vertebral column. On median 3-D multiplanar reconstruction images, the dens angle (DA) was measured as were the lengths of the dens and the body of the axis; the dens-to-axis length ratio (ratio of the dens length to the axis body length [DALR]) was calculated. Data were compared among dog groups. RESULTS The DALR in nonaffected TBDs and Beagles did not differ significantly. The mean DALR for AAI-affected TBDs was significantly lower than that for nonaffected TBDs. The mean DA of AAI-affected TBDs was significantly greater than that of Beagles and nonaffected TBDs. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that a low DALR might be associated with a high probability of dens abnormalities in TBDs. Additionally, dens length in AAI-affected TBDs appeared to be smaller than that in non-AAI-affected TBDs, given the low DALR in AAI-affected TBDs. Further investigations to determine reference ranges of the DA and DALR and the potential usefulness of those variables as diagnostic markers for AAI in TBDs are warranted. PMID- 29182396 TI - Effect of bilateral ventriculocordectomy via ventral laryngotomy on laryngeal airway resistance in larynges of canine cadavers. AB - OBJECTIVE To evaluate the effect of bilateral ventriculocordectomy via ventral laryngotomy on laryngeal airway resistance (LAR) in canine cadaver larynges. SAMPLE 6 clinically normal canine cadaver larynges. PROCEDURES LAR was determined for each specimen before (baseline) and after bilateral ventriculocordectomy with the epiglottis open and closed. After ventral laryngotomy was performed, the vocal cords were sharply excised, and the incised mucosal edges were apposed with 4-0 glycomer 631 suture in a simple continuous pattern. The thyroid cartilage was apposed with 3-0 polypropylene suture in a simple continuous pattern. RESULTS With the epiglottis closed, baseline median LAR was 27.6 cm H2O/L/s (range, 21.2 to 30.6 cm H2O/L/s), which did not differ significantly from the median LAR after bilateral ventriculocordectomy (24.7 cm H2O/L/s [range, 20.6 to 27.7 cm H2O/L/s]). With the epiglottis open, baseline median LAR was 7.3 cm H2O/L/s (range, 5.4 to 7.8 cm H2O/L/s), which did not differ significantly from the median LAR after bilateral ventriculocordectomy (7.2 cm H2O/L/s [range, 6.6 to 7.6 cm H2O/L/s]). CONCLUSIONS AND CLINICAL RELEVANCE Bilateral ventriculocordectomy did not affect LAR with an open epiglottis in canine cadaver larynges. Therefore, it may not be an effective treatment for laryngeal paralysis. It also did not affect LAR with a closed epiglottis, which may indicate protection against aspiration pneumonia. PMID- 29182399 TI - Application of camelid heavy-chain variable domains (VHHs) in prevention and treatment of bacterial and viral infections. AB - Camelid heavy-chain variable domains (VHHs) are the smallest, intact, antigen binding units to occur in nature. VHHs possess high degrees of solubility and robustness enabling generation of multivalent constructs with increased avidity - characteristics that mark their superiority to other antibody fragments and monoclonal antibodies. Capable of effectively binding to molecular targets inaccessible to classical immunotherapeutic agents and easily produced in microbial culture, VHHs are considered promising tools for pharmaceutical biotechnology. With the aim to demonstrate the perspective and potential of VHHs for the development of prophylactic and therapeutic drugs to target diseases caused by bacterial and viral infections, this review article will initially describe the structural features that underlie the unique properties of VHHs and explain the methods currently used for the selection and recombinant production of pathogen-specific VHHs, and then thoroughly summarize the experimental findings of five distinct studies that employed VHHs as inhibitors of host pathogen interactions or neutralizers of infectious agents. Past and recent studies suggest the potential of camelid heavy-chain variable domains as a novel modality of immunotherapeutic drugs and a promising alternative to monoclonal antibodies. VHHs demonstrate the ability to interfere with bacterial pathogenesis by preventing adhesion to host tissue and sequestering disease-causing bacterial toxins. To protect from viral infections, VHHs may be employed as inhibitors of viral entry by binding to viral coat proteins or blocking interactions with cell surface receptors. The implementation of VHHs as immunotherapeutic agents for infectious diseases is of considerable potential and set to contribute to public health in the near future. PMID- 29182397 TI - Breast tissue density change after oophorectomy in BRCA mutation carrier patients using visual and volumetric analysis. AB - OBJECTIVE: BRCA1/2 mutations account for 30-50% of hereditary breast cancers and bilateral oophorectomy is associated with a reduced risk of breast cancer in these patients. Breast density is a well-established breast cancer risk factor and is also associated with increased risk in BRCA carriers. The aim of the study was to evaluate the impact of oophorectomy on mammographic breast density and to assess which method of breast density assessment is more sensitive to change over time. METHODS: Retrospective study of 50 BRCA1/2 patients who underwent bilateral oophorectomy and had at least a baseline and post-surgery mammogram. Mammographic breast density was determined by Volpara and consensus visual assessment by two radiologists. The primary endpoint was change in density between baseline and the first mammogram post-surgery. RESULTS: At baseline, there was a non-significant trend for decreased density with increasing age. Volumetric breast density (VBD) significantly decreased after oophorectomy from a median VBD of 12.5% at baseline to 10.2% post-surgery which was driven by a reduction in fibroglandular volume. There was a higher absolute decrease in VBD in patients aged between 40-50 (p < 0.01). Using Volpara Density Grades (analogous to BI-RADS 4th edition density categories), 84% of females displayed a decrease in density category over the study period compared to only 76% using the radiologists' visual classification (p < 0.001) Conclusion: Oophorectomy is associated with a decrease in breast density and younger patients exhibit a larger absolute decrease. Volpara is more sensitive to identify change over time compared to visual assessment. Advances in knowledge: Oophorectomy is associated with a significant decrease in VBD in patients with BRCA mutations and Volpara Density Grades were more sensitive to identify decreases in density compared to visually assessed BI-RADS categories. Decreases in breast density following oophorectomy surgery in BRCA patients may be one of the mechanisms contributing to the observed decreased breast cancer risk after surgery. However, further studies are needed to investigate the relationship between breast density, oophorectomy and breast cancer risk in BRCA patients. PMID- 29182401 TI - The Association of Cataract and Lens Epithelial Cell Apoptosis in Patients with Pseudoexfoliation Syndrome. AB - PURPOSE: The aim of this study was to measure the density of apoptotic lens epithelial cells (LECs) and to determine its association with cataract formation in eyes with pseudoexfoliation syndrome (PEX). MATERIALS AND METHODS: Twenty-one eyes of 21 patients diagnosed with PEX without glaucoma (Group 1) and 22 eyes of 22 subjects without PEX (Group 2) were enrolled in this study. During cataract surgery, anterior capsule samples were obtained by the 5.5 mm continuous curvilinear capsulorhexis method. Apoptosis was determined with a TUNEL kit (Boster, Wuhan, China) according to the manufacturer's protocol. Four fields in each pathology preparation were chosen randomly under a microscope, and 100 cells were counted in each field to calculate the apoptosis rates. RESULTS: Forty-three eyes of 43 subjects were enrolled in this study. There were no significant differences in age or sex between the two studied groups (p > 0.05). Under a microscope, the LECs were stained light blue and their nuclei were oval shaped. Positive stained cells were found occasionally in Group 2, while a significant amount of black-brown positively stained LECs with condensed nuclei was found in Group 1. The apoptosis rates were 35.2 +/- 2.1% and 14.1 +/- 1% in Groups 1 and 2, respectively. The proportion of positively stained LECs was higher in Group 1 (p < 0.001). CONCLUSION: Our study suggests that apoptosis in LECs is the pathophysiological mechanism for the higher rate of cataracts in PEX patients, in addition to the ocular ischemia hypothesis. PMID- 29182400 TI - Interleukin-4 Gene Intron 3 VNTR Polymorphism in Type 2 Diabetes Patients with Peripheral Neuropathy. AB - OBJECTIVE: Diabetic peripheral neuropathy (DPN) is one of late complications of diabetes mellitus. The aim of this study was to evaluate the association between variable number tandem repeat (VNTR) polymorphism in intron 3 of interleukin-4 gene and risk of DPN. METHODS: We examined 926 T2DM patients and 420 healthy controls. In the patient group, 44% had DPN. Genomic DNA was isolated from all subjects and genotyped for the IL-4 VNTR polymorphism by polymerase chain reaction (PCR). RESULTS: No significant difference was observed in the frequency of minor P1 allele between T2DM patients and controls (OR 1.00, 95% CI 0.81-1.23, p = 0.988). The distribution of IL-4 VNTR polymorphism was compared between patients with DPN and those without it. The polymorphism was not significantly associated with DPN in studied subjects. In comparison of 406 T2DM patients with DPN and 520 patients without it, the OR (95% CI) for P1 allele was 0.82 (0.65 1.04), p = 0.10 and for P1P1 genotype 1.00 (0.53-1.89), p = 0.991. When two subgroups of patients with DPN, those with cardiovascular disease (CVD) and without CVD, were compared, subgroup with coexisting CVD had significantly higher frequency of P1 allele than patients without CVD, with odds ratio for the P1 allele 3.27 (95% CI 1.83-5.83), p = 0.0001. CONCLUSION: Our results demonstrated that VNTR polymorphism in the IL-4 gene is associated with DPN in type 2 diabetes patients with coexisting CVD. PMID- 29182403 TI - Long-Distance Triathletes' Intentions to Manipulate Energy and Macronutrient Intake Over a Training Macrocycle. AB - This study explored the information sources long-distance triathletes used to inform their training and nutrition plans, and evaluated these plans over a training macrocycle. Seventy-four long-distance triathletes completed the online survey. Coaches were the most popular training information source (69%), whereas nonprofessional sources (internet 65%, other athletes 53%) were more popular than nutritionists (29%) for nutrition information. Attributes valued most in an information source were: source prior personal experience, individualized advice, breadth of knowledge, and credibility. Sixty-five percent of participants reported previously manipulating dietary intake to improve performance. Forty three percent reported carbohydrate loading previously, but only 29% planned to carbohydrate load for their upcoming event. Thirty-six percent of participants planned to reduce carbohydrate intake at some point in training, predominantly early (28%) and toward the end (22%) of their macrocycles. Twenty percent of participants planned to maintain energy intake early, and increase (14%) or maintain energy intake (15%) mid-cycle. Triathletes' training plans showed intentions for concurrent increases in volume and intensity, rather than a classical periodized training progression. Limitations of this study include the lack of diet intake and training data, quantitative comparison with dietary guidelines and high/low carbohydrate classification, and an overrepresentation of women in the study cohort. This research showed the popularity of the internet and other athletes to inform triathletes' nutrition plans, and revealed intentions to reduce carbohydrate intakes alongside training load increases, contrary to professional guidelines. Understanding athletes' intentions and sources of nutrition information is crucial to developing effective nutrition education strategies. PMID- 29182402 TI - Individual versus interprofessional team performance in formulating care transition plans: A randomised study of trainees from five professional groups. AB - Health professions trainees' performance in teams is rarely evaluated, but increasingly important as the healthcare delivery systems in which they will practice move towards team-based care. Effective management of care transitions is an important aspect of interprofessional teamwork. This mixed-methods study used a crossover design to randomise health professions trainees to work as individuals and as teams to formulate written care transition plans. Experienced external raters assessed the quality of the written care transition plans as well as both the quality of team process and overall team performance. Written care transition plan quality did not vary between individuals and teams (21.8 vs. 24.4, respectively, p = 0.42). The quality of team process did not correlate with the quality of the team-generated written care transition plans (r = -0.172, p = 0.659). However, there was a significant correlation between the quality of team process and overall team performance (r = 0.692, p = 0.039). Teams with highly engaged recorders, performing an internal team debrief, had higher-quality care transition plans. These results suggest that high-quality interprofessional care transition plans may require advance instruction as well as teamwork in finalising the plan. PMID- 29182404 TI - Evaluation of the Effect of Everolimus on Retinal Pigment Epithelial Cells and Experimental Proliferative Vitreoretinopathy. AB - PURPOSE: Failure of retinal detachment surgery is most commonly due to the development of proliferative vitreoretinopathy (PVR). Everolimus is an inhibitor of mammalian target of rapamycin (mTOR), and is available as oral tablets. In this study, we investigated the effect of everolimus on retinal pigment epithelial cells and modification of the severity of experimental PVR. METHODS: In our in vitro studies, primary culture of retinal pigment epithelium (RPE) cells was obtained from pigmented Rex rabbits. Cell proliferation was assayed with the tetrazolium dye cytotoxicity test, and cell migration assay was performed in 24-well transwell units with 8-MUm filters. In the in vivo study, pigmented Rex rabbits weighing between 2 and 2.5 kg were used. Each rabbit eye underwent gas compression; one week later, 5 * 104 RPE cells were injected into the vitreous cavity to induce PVR, and each eye was graded with indirect ophthalmoscopy on days 1, 3, 7, 14, 21, and 28. The rabbits were administered everolimus (0.5 mg/day orally) from the day of PVR induction. Total proteins extracted from RPE cells and dissected retinal samples were processed for Western blotting analysis of mTOR and ribosomal protein S6 (RPS6). RESULTS: The in vitro studies showed that everolimus significantly inhibited the proliferation of RPE cells at 0.1 MUg/ml; additionally, at 10 MUg/ml, it suppressed the migration of RPE cells and significantly suppressed the expression of mTOR and RPS6 in RPE cells. The in vivo study did not show any benefit of oral everolimus (0.5 mg/day) in suppressing experimental PVR. Thus, everolimus significantly suppressed the expression of mTOR and RPS6 in PVR. CONCLUSIONS: Everolimus suppressed the proliferation and migration of RPE cells in vitro. Oral everolimus (0.5 mg/day) suppressed the expression of mTOR and RPS6 in the retina, but showed no effect in suppressing experimental PVR. PMID- 29182405 TI - Decrease in the Frequency of Circulating CD56+CD161+ NK Cells in Human Visceral Leishmaniasis. AB - BACKGROUND: Natural Killer (NK) cell plays an important role in the innate immune system and is known to produce IFN-gamma at an early stage of infection that is essential to eliminate intracellular infection like Leishmania spp. It is already established that Leishmania parasite inhibits the activity of NK cells, avoiding the encounter with the early innate immune response. This, in turn, favors establishment and further dissemination of the infection. METHODS: In the present study, we have tried to measure the frequency of different phenotypic subsets of NK cells among visceral leishmaniasis (VL) patients. RESULTS: We have phenotyped three distinct three distinct subsets (CD56-CD161+, CD56+CD161-, and CD56+CD161+) of NK (CD3-) cell using their specific markers CD161 and CD56. CONCLUSION: Interestingly, we observed selective loss of CD56+CD161+ subset of circulating NK (CD3-) cells. Importantly, the other subsets (i.e., CD56-CD161+ and CD56+CD161-) of circulating NK cells remain unaffected as compared with healthy subjects. PMID- 29182406 TI - Assessing quality of care through client satisfaction at an interprofessional student-run free clinic. AB - Student-run free clinics (SRFCs) have become important contributors not only to improve access to primary-care services for homeless and uninsured populations but also to enhance health sciences student education. In order for SRFCs to reliably provide high quality healthcare services and educationally benefit students, it is imperative to assess client perceptions of the quality of care provided. The objective of this study was to evaluate the delivery of healthcare services through a client satisfaction questionnaire at the University of California, Los Angeles Mobile Clinic Project (UCLA MCP). From 2012 to 2015, 194 questionnaires that addressed demographic information, satisfaction with services and client outcomes were analysed. Satisfaction scores were evaluated on a four point scale and differences in the composite satisfaction scores were assessed using Mann-Whitney U-tests. Half (50%) of the client respondents report that UCLA MCP is their primary source of health care (MCP primary care clients), while 81.3% reported that the clinic improved access to other healthcare resources. Overall, clients are highly satisfied with their experiences (Range: 3.5-3.9) and 62% have recommended our services to others. While MCP primary-care clients report significantly higher satisfaction scores than non-primary-care clients on average (p < 0.01), the mean composite scores for all subgroups are consistently high. The UCLA MCP clients perceive the clinic to provide high-quality healthcare services. This article presents a framework that may help other SRFCs evaluate clients' perception of the quality of their care, an essential building block for effective physician-client relationships. PMID- 29182408 TI - Rapid Weight Loss Is Not Associated With Competitive Success in Elite Youth Olympic-Style Boxers in Europe. AB - PURPOSE: To examine the influence of rapid weight loss (RWL) on competitive success in elite youth Olympic-style boxers. In addition, this study examined the practice and prevalence of weight reduction, weight-management protocols, and related symptoms in youth boxers from 12 European countries (N = 83, all males, mean [SD] age 17.1 [0.9] y). METHODS: The data were collected using an extensive questionnaire on weight cutting and its associated protocols and symptoms prior to highest-level continental championships. Competition results were obtained at follow-up using a dichotomous variable: medal winning vs nonwinning at the European Championships. RESULTS: Binary logistic regression analysis indicated that "boxing experience" was significantly related to the criterion competitive outcome (odds ratio = 1.33; 95% confidence interval, 1.06-1.66; Nagelkerke R2 = .11), with a higher likelihood of competitive success for more-experienced boxers. Of all the youth boxers, only 25% were included in the RWL group, irrespective of their weight-class stratification. More than 45% of all the youth boxers self-reported the simultaneous combination of different weight-cutting methods that are known to be serious health hazards. Finally, 33% of the boxers experienced muscle weakness as a consequence of RWL. CONCLUSIONS: Our study provided evidence of pathogenic weight-management protocols that are widely adopted by youth boxers, and yet the present outcomes showed that RWL did not translate into competitive success in these elite Olympic-style boxers in Europe. Therefore, the authors suggest a mandatory educational program that should simultaneously target all the mentioned issues including both health- and performance-threatening consequences. PMID- 29182407 TI - Metformin is associated with reduced cell proliferation in human endometrial cancer by inbibiting PI3K/AKT/mTOR signaling. AB - Metformin recently gained traction as potential anti-endometrial cancer agent for its new applications. However, the underlying mechanisms of the anti-cancer effect of metformin in the endometrial cancer have not yet been fully elucidated. Sixty-five patients diagnosed as endometrial carcinoma were grouped into (n = 33) and non-treatment mixed (n = 32) for analysis. Thirty healthy donors were recruited as controls. We attempt to investigate the effect of metformin on Ki 67, PI3K, p-AKT, p-S6K1, and p-4EBP1 staining in human endometrial cancer by immunohistochemical staining. We found that increased Ki-67 expression in women with endometrial cancer, which were reversed by conventional anti-diabetic doses of metformin in present work. In parallel, the reduced PI3K, p-AKT, p-S6K1, and p 4EBP1 staining induced by metformin appeared to play an important role for the anti-proliferative effects of metformin in endometrial cancer patients. Metformin significantly decreased proliferation in human endometrial cancer may by inhibiting PI3K/AKT/mTOR signaling. Our present results add to the growing body of evidence supporting metformin as a potential anti-cancer agent in endometrial cancer. PMID- 29182409 TI - Association between HLA-DQB1 polymorphisms and pemphigus vulgaris: A meta analysis. AB - OBJECTIVE: This study was performed to systematically summarize the results on the association of HLA-DQB1 polymorphisms with pemphigus vulgaris (PV) and other related factors. METHODS: A comprehensive literature search of PubMed, The Cochrane Library, Embase, and Google Scholar database was conducted to identify relevant articles in English, with the last report up to November 1, 2016. Heterogeneity test was performed, and publication bias was evaluated. Stata software 12.0 was used to perform the meta-analysis. Odds ratios (ORs) and 95% confidence intervals (CI) were used to describe the correlation by random-effects model. RESULTS: 18 studies were obtained after searching databases: 10 studies were about Caucasian, and 8 articles were about non-Caucasian. Meta-analysis revealed that the allele and phenotype frequencies of DQB1*05 were markedly higher in PV patients than in controls [P < 0.001, OR: 2.640, 95%CI: 1.570-4.441; P = 0.030, OR 3.688, 95%CI: 1.138-11.946]. In addition, DQB1*03 was significantly increased at the allele level [P < 0.001, OR: 2.080, 95%CI: 1.507-2.869], and DQB1*02 was significantly decreased in PV at the allele and phenotype levels [P = 0.002, OR: 0.450, 95%CI: 0.289-0.702; P = 0.001, OR: 0.293, 95%CI: 0.146-0.587]. When based on each subtype of HLA-DQB1, DQB1*05:03 and DQB1*03:02 may play susceptibility roles in PV, and DQB1*03:03, DQB1*05:01 and DQB1*06:01 are negatively associated with PV. CONCLUSION: In summary, our study suggests that alleles from the groups DQB1*05 and DQB1*03, concretely DQB1*05:03 and DQB1*03:02, respectively, may be the susceptibility factors for PV at allele and phenotype levels, whereas DQB1*05:01, DQB1*02, DQB1*06:01, and DQB1*03:03 are negatively associated with PV. PMID- 29182410 TI - The Effect of Periodization and Training Intensity Distribution on Middle- and Long-Distance Running Performance: A Systematic Review. AB - This review aimed to examine the current evidence for 3 primary training intensity distribution types: (1) pyramidal training, (2) polarized training, and (3) threshold training. Where possible, the training intensity zones relative to the goal race pace, rather than physiological or subjective variables, were calculated. Three electronic databases (PubMed, Scopus, and Web of Science) were searched in May 2017 for original research articles. After analysis of 493 resultant original articles, studies were included if they met the following criteria: (1) Their participants were middle- or long-distance runners; (2) they analyzed training intensity distribution in the form of observational reports, case studies, or interventions; (3) they were published in peer-reviewed journals; and (4) they analyzed training programs with a duration of 4 wk or longer. Sixteen studies met the inclusion criteria, which included 6 observational reports, 3 case studies, 6 interventions, and 1 review. According to the results of this analysis, pyramidal and polarized training are more effective than threshold training, although the latest is used by some of the best marathon runners in the world. Despite this apparent contradictory finding, this review presents evidence for the organization of training into zones based on a percentage of goal race pace, which allows for different periodization types to be compatible. This approach requires further development to assess whether specific percentages above and below race pace are key to inducing optimal changes. PMID- 29182411 TI - Interprofessional teamwork in comprehensive primary healthcare services: Findings from a mixed methods study. AB - This article draws on data from a 5-year project that examined the effectiveness of Comprehensive primary healthcare (CPHC) in local communities. A hallmark of CPHC services is interprofessional teamwork. Drawing from this study, our article presents factors that enabled, or hindered, healthcare teams working interprofessionally in Australian primary healthcare (PHC) services. The article reports on the experiences of teams working in six Australian PHC services (four managed by state governments, one non-government sexual health organisation, and one Aboriginal community-controlled health service) during a time of significant health sector restructure. Findings are drawn from two key methods: an online survey of practitioners and managers (n = 154), and interviews with managers and practitioners (n = 60) from the six study sites. The majority of survey respondents worked with other health professionals in their service to provide interprofessional care to clients. Processes included formal team meetings, case conferencing, referring clients to other health professionals if needed, informal communication with other health professionals about clients, and team-based delivery of care. A range of interrelated factors affected interprofessional work at the services, from contextual, organisational, processual, and relational domains. Funding cuts and policy changes that saw a reorientation and re medicalisation of South Australian services undermined interprofessional work, while a shared CPHC culture and commitment among some staff was helpful in resisting some of these effects. The co-location of services was a factor in PHC teams working interprofessionally and not only enabled some PHC teams to work more interprofessionally but also created barriers to interprofessional teamwork through disruption resulting from restructuring of services. Our study indicates the importance of decision makers taking into account the potential effects of policy and structural changes on interprofessional teamwork. Decision makers should strive to minimise unintended negative effects of changes on the functioning of interprofessional teams. PMID- 29182412 TI - The Effect of Water Loading on Acute Weight Loss Following Fluid Restriction in Combat Sports Athletes. AB - Novel methods of acute weight loss practiced by combat sport athletes include "water loading," the consumption of large fluid volumes for several days prior to restriction. We examined claims that this technique increases total body water losses, while also assessing the risk of hyponatremia. Male athletes were separated into control (n = 10) and water loading (n = 11) groups and fed a standardized energy-matched diet for 6 days. Days 1-3 fluid intake was 40 and 100 ml/kg for control and water loading groups, respectively, with both groups consuming 15 ml/kg on Day 4 and following the same rehydration protocol on Days 5 and 6. We tracked body mass (BM), urine sodium, urine specific gravity and volume, training-related sweat losses and blood concentrations of renal hormones, and urea and electrolytes throughout. Physical performance was assessed preintervention and postintervention. Following fluid restriction, there were substantial differences between groups in the ratio of fluid input/output (39%, p < .01, effect size = 1.2) and BM loss (0.6% BM, p = .02, effect size = 0.82). Changes in urine specific gravity, urea and electrolytes, and renal hormones occurred over time (p < .05), with an interaction of time and intervention on blood sodium, potassium, chloride, urea, creatinine, urine specific gravity, and vasopressin (p < .05). Measurements of urea and electrolyte remained within reference ranges, and no differences in physical performance were detected over time or between groups. Water loading appears to be a safe and effective method of acute BM loss under the conditions of this study. Vasopressin-regulated changes in aquaporin channels may potentially partially explain the mechanism of increased body water loss with water loading. PMID- 29182413 TI - Energetic Profile of the Basketball Exercise Simulation Test in Junior Elite Players. AB - PURPOSE: To analyze the energetic profile of the Basketball Exercise Simulation Test (BEST). METHODS: Ten male elite junior basketball players (age 15.5 [0.6] y, height 180 [9] cm, and body mass 66.1 [11.2] kg) performed a modified BEST (20 circuits consisting of jumping, sprinting, jogging, shuffling, and short breaks) simulating professional basketball game play. Circuit time, sprint time, sprint decrement, oxygen uptake (VO2), heart rate, and blood lactate concentration (blc) were obtained. Metabolic energy and metabolic power above rest (Wtot and Ptot), as well as energy share in terms of aerobic (Waer), glycolytic (Wblc), and high energy phosphates (WPCr), were calculated from VO2 during exercise, net lactate production, and the fast component of postexercise VO2 kinetics, respectively. RESULTS: Waer, Wblc, and WPCr reflect 89% (2%), 5% (1%), and 6% (1%) of total energy needed, respectively. Assuming an aerobic replenishment of PCr energy stores during short breaks, the adjusted energy share yielded Waer 66% (4%), Wblc 5% (1%), and WPCr 29% (1%). Waer and WPCr were negatively correlated (-0.72 and 0.59) with sprint time, which was not the case for Wblc. CONCLUSIONS: Consistent with general findings on energy system interaction during repeated high-intensity exercise bouts, the intermittent profile of the BEST relies primarily on aerobic energy combined with repetitive supplementation by anaerobic utilization of high energy phosphates. PMID- 29182414 TI - Cell-Free DNA as an Earlier Predictor of Exercise-Induced Performance Decrement Related to Muscle Damage. AB - PURPOSE: To evaluate whether cell-free DNA (cfDNA) levels increase immediately after an acute light and heavy resistance exercise (RE) bout and whether cfDNA levels are associated with functional muscle capacity up to 48 h after an exercise session. METHODS: Twenty healthy volunteers performed 3 sets of leg press RE with 80% of 1-repetition maximum (1RM) (RE80) or 40% of 1RM (RE40) with similar exercise volume. Blood lactate was measured after completion of the 3 sets. Creatine kinase, cfDNA, and jump performance were evaluated before (pre) exercise, immediately postexercise (post-0h), and every 24 h until 48 h. RESULTS: Lactate concentration increased similarly in both groups (RE40 4.0 [1.3] mmol/L; RE80 4.8 [1.3] mmol/L). No changes were observed in squat-jump and countermovement-jump performance after RE40; however, both jumps remained reduced until 48 h in the RE80 group. Creatine kinase concentration increased post-24h only in the RE80 group (pre 128.8 [73.7] U/L to post-24h 313.8 [116.4] U/L). cfDNA concentration increased post-0h only in the RE80 group (pre 249.8 [82.3] ng/mL to post-0h 406.3 [67.2] ng/mL). There was a negative correlation between post-0h cfDNA concentration and post-24h squat jump (r = -.521; P = .01) and post 0h cfDNA concentration and post-24h countermovement jump (r = -.539; P = .01). CONCLUSION: cfDNA increases in response to RE intensity even when not performed until exhaustion. cfDNA measured immediately after RE is a promising biomarker for muscle-performance decrement up to 48 h after a RE bout.

METHODS: A total of 11 cyclists performed 44 randomized and counterbalanced graded exercise tests (100-500 W) at 70-, 85-, and 100-rpm cadences in seated and standing positions on 3 different Hammer units, while a scientific SRM system continuously recorded cadence and power output data. RESULTS: No significant differences were detected between the 3 Hammer devices and the SRM for any workload, cadence, or pedaling condition (P value between 1.00 and .350), except for some minor differences (P = .03 and .04) found in the Hammer 1 at low workloads and for Hammer 2 and 3 at high workloads, all in seated position. Strong intraclass correlation coefficients were found between the power output values recorded by the Hammers and the SRM (>=.996; P = .001), independently from the cadence condition and seated position. Bland-Altman analysis revealed low bias (-5.5 to 3.8) and low SD of bias (2.5-5.3) for all testing conditions, except marginal values found for the Hammer 1 at high cadences and seated position (9.6 [6.6]). High absolute reliability values were detected for the 3 Hammers (150-500 W; coefficient of variation <1.2%; SEM <2.1). CONCLUSIONS: This new Cycleops trainer is a valid and reliable device to drive and measure power output in cyclists, providing an alternative to larger and more expensive laboratory ergometers and allowing cyclists to use their own bicycles. PMID- 29182416 TI - Ex vivo Stimulation of Lymphocytes with IL-10 Mimics Sepsis-Induced Intrinsic T Cell Alterations. AB - Profound T-cell alterations are observed in septic patients in association with increased risk of secondary infection and mortality. The pathophysiological mechanisms leading to such dysfunctions are not completely understood and direct and indirect mechanisms have been described. In this study we evaluated whether ex vivo stimulation of lymphocytes with IL-10, an immunosuppressive cytokine released at the systemic level during sepsis, could mimic sepsis-induced intrinsic T-cell alterations. We showed that recombinant human IL-10 priming of T cells altered their proliferative response to anti-CD2/CD3/CD28 antibody-coated beads and PHA stimulations, in a dose-dependent manner independently of accessory cells. This priming also significantly decreased T-cell secretion of IL-2 and IFNgamma following stimulation. Furthermore, we demonstrated that IL-10 reduction of T-cell functionality was associated with increased FOXP3 expression in CD4+CD25+CD127- regulatory T cells as observed in sepsis. Finally, we found that blocking the increased IL-10 concentration in plasma from septic shock patients increased the proliferative response of responding T cells from healthy controls. We describe here an ex vivo model recapitulating features of sepsis-induced intrinsic T-cell alterations. This should help, in further studies, to decipher the pathophysiological mechanisms of T-cell alterations induced after septic shock.

AB - The purpose of this investigation was to (1) quantify the training load practices of a professional soccer goalkeeper and (2) investigate the relationship between the training load observed and the subsequent self-reported wellness response. One male goalkeeper playing for a team in the top league of the Netherlands participated in this case study. Training load data were collected across a full season using a global positioning system device and session-RPE (rating of perceived exertion). Data were assessed in relation to the number of days to a match (MD- and MD+). In addition, self-reported wellness response was assessed using a questionnaire. Duration, total distance, average speed, PlayerLoadTM, and load (derived from session-RPE) were highest on MD. The lowest values for duration, total distance, and PlayerLoadTM were observed on MD-1 and MD+1. Total wellness scores were highest on MD and MD-3 and were lowest on MD+1 and MD-4. Small to moderate correlations between training load measures (duration, total distance covered, high deceleration efforts, and load) and the self-reported wellness response scores were found. This exploratory case study provides novel data about the physical load undertaken by a goalkeeper during 1 competitive season. The data suggest that there are small to moderate relationships between training load indicators and self-reported wellness response. This weak relation indicates that the association is not meaningful. This may be due to the lack of position-specific training load parameters that practitioners can currently measure in the applied context. PMID- 29182418 TI - Associations Between Bicycling and Reduced Fall-Related Physical Performance in Older Adults. AB - Falls among older adults remain a significant public health issue. Bicycling positively influences falls risk factors including reduced balance, muscle weakness, and low self-perceived confidence in maintaining balance. However, this association has not been systematically examined. We recruited 107 community dwelling participants aged 65 years and older in the Netherlands to determine the relationship between bicycling and falls risk factors. Participants completed three questionnaires on cycling behavior and balance confidence, and also undertook five falls-related physical performance tasks encompassing tests of balance, strength, gait, and endurance. On average, current bicyclists showed significantly better scores in all physical tasks and confidence compared with nonriders ranging from a 10% difference in 6-m walk time to a 141% difference in single-leg balance time (all ps = .01). Type of bike used and duration of bicycling displayed varied associations (.01 < ps < .79). Our findings suggest that bicycle riding warrants further prospective investigation for fall prevention and active aging. PMID- 29182419 TI - Psychometric Properties of the Modified Social Environment Questionnaire in Chinese Older Adults. AB - This study evaluated the psychometric properties of a Chinese version of the 24 item Social Environment Questionnaire (SEQ-C). Confirmatory factor analysis was used to examine the factor validity and measurement invariance (Purpose 1) of the SEQ-C in 453 older adults in Hong Kong. Convergent validity (Purpose 2) and test retest reliability (Purpose 3) were also measured. The results of the confirmatory factor analysis and measurement invariance supported the four-factor structure (representing companionship, encouragement, neighborhood social cohesion, and role models) of the SEQ-C, in a 15-item model that closely fitted the data. The SEQ-C was also found to have acceptable to satisfactory internal consistency, test-retest reliability, composite reliability, and moderate convergent validity in correlating perceived social support. This study showed that the SEQ-C is a suitable means of measuring the social environments of older adults in Hong Kong. PMID- 29182420 TI - Timeliness of vaccination in infants followed by primary-care pediatricians in France. AB - Vaccination status is more often evaluated by up-to-date vaccination coverage rather than timeliness of immunization. Delaying vaccination may be dangerous during infancy. The aim of this study was to identify the importance of potentially dangerous vaccination delay (previously defined) and determinants of these delays. We conducted a national, prospective, vaccination survey in June 2014, with primary care pediatricians. Children, 2 to 24 months of age, were included. Data about vaccination were extracted from their health books. Additional data were collected through a standardized questionnaire. Vaccine coverage rate and timeliness were calculated. Variables associated with a potentially dangerous vaccination delay as previously defined were determined by a multivariable analysis. Among the 443 included children (mean age 10.8 months, 49% males), 13% to 58% of vaccine doses according to vaccine type were done with a potentially dangerous delay. Globally, 47% of children had at least one potentially dangerous immunization delay. We identified two risk factors of potentially dangerous delayed immunization globally: an increasing age of the child (adjusted odds ratio: 1.2, 95% confidence interval [CI]: 1.1-1.3, p < 10 3), and a working mother (adjusted OR: 2.4, 95% CI: 1.2-4.7, p = 0.01). Despite a good vaccine coverage rate, a large number of children had a potentially dangerous vaccination delay. A high level of vigilance regarding these immunization delays, and particularly to the patients sharing the risk factors of immunization delay identified here, can increase quality and effectiveness of the vaccine protection. PMID- 29182422 TI - Salivary Biomarkers and Training Load During Training and Competition in Paralympic Swimmers. AB - CONTEXT: Stress responses in athletes can be attributed to training and competition, where increased physiological and psychological stress may negatively affect performance and recovery. PURPOSE: To examine the relationship between training load (TL) and salivary biomarkers immunoglobulin A (IgA), alpha amylase (AA), and cortisol across a 16-wk preparation phase and 10-d competition phase in Paralympic swimmers. METHODS: Four Paralympic swimmers provided biweekly saliva samples during 3 training phases-(1) normal training, (2) intensified training, and (3) taper-as well as daily saliva samples in the 10-d Paralympic competition (2016 Paralympic Games). TL was measured using session rating of perceived exertion. RESULTS: Multilevel analysis identified a significant increase in salivary immunoglobulin A (sIgA: 94.98 [27.69] MUg.mL-1), salivary alpha-amylase (sAA: 45.78 [19.07] MUg.mL-1), and salivary cortisol (7.92 [2.17] nM) during intensified training concurrent with a 38.3% increase in TL. During the taper phase, a 49.5% decrease in TL from the intensified training phase resulted in a decrease in sIgA, sAA, and salivary cortisol; however, all 3 remained higher than baseline levels. A further significant increase was observed during competition in sIgA (168.69 [24.19] MUg.mL-1), sAA (35.86 [16.67] MUg.mL 1), and salivary cortisol (10.49 [1.89] nM) despite a continued decrease (77.8%) in TL from the taper phase. CONCLUSIONS: Results demonstrate that performance in major competition such as Paralympic games, despite a noticeable reduction in TL, induces a stress response in athletes. Because of the elevated stress response observed, modifications to individual postrace recovery protocols may be required to enable athletes to maximize performance across all 10 d of competition. PMID- 29182421 TI - Feeding strategy shapes gut metagenomic enrichment and functional specialization in captive lemurs. AB - Many studies have demonstrated the effects of host diet on gut microbial membership, metagenomics, and fermentation individually; but few have attempted to interpret the relationship among these biological phenomena with respect to host features (e.g. gut morphology). We quantitatively compare the fecal microbial communities, metabolic pathways, and fermentation products associated with the nutritional intake of frugivorous (fruit-eating) and folivorous (leaf eating) lemurs. Our results provide a uniquely multidimensional and comparative perspective on the adaptive dynamics between host and microbiome. Shotgun metagenomic sequencing revealed significant differential taxonomic and metabolic pathway enrichment, tailored to digest and detoxify different diets. Frugivorous metagenomes feature pathways to degrade simple carbohydrates and host-derived glycosaminoglycans, while folivorous metagenomes are equipped to break down phytic acid and other phytochemical compounds in an anaerobic environment. We used nuclear magnetic resonance based metabolic profiling of fecal samples to link metabolic pathways to fermentation products, confirming that the dissimilar substrates provided in each diet select for specific microbial functions. Fecal samples from frugivorous lemurs contained significantly different profiles of short chain fatty acids, alcohol fermentation products, amino acids, glucose, and glycerol compared to folivorous lemurs. We present the relationships between these datasets as an integrated visual framework, which we refer to as microbial geometry. We use microbial geometry to compare empirical gut microbial profiles across different feeding strategies, and suggest additional utility as a tool for hypothesis-generation. PMID- 29182423 TI - The Digest. PMID- 29182424 TI - Bioactivation of cyclopropyl rings by P450: an observation encountered during the optimisation of a series of hepatitis C virus NS5B inhibitors. AB - 1. Due to its unique C-C and C-H bonding properties, conformational preferences and relative hydrophilicity, the cyclopropyl ring has been used as a synthetic building block in drug discovery to modulate potency and drug-like properties. During an effort to discover inhibitors of the hepatitis C virus non-structural protein 5B with improved potency and genotype-coverage profiles, the use of a pyrimidinylcyclopropylbenzamide moiety linked to a C6-substituted benzofuran or azabenzofuran core scaffold was explored in an effort to balance antiviral potency and metabolic stability. 2. In vitro metabolism studies of two compounds from this C6-substituted series revealed an NADPH-dependent bioactivation pathway leading to the formation of multiple glutathione (GSH) conjugates. Analysis of these conjugates by LC-MS and NMR demonstrated that the cyclopropyl group was the site of bioactivation. Based on the putative structures and molecular weights of the cyclopropyl-GSH conjugates, a multi-step mechanism was proposed to explain the formation of these metabolites by P450. This mechanism involves hydrogen atom abstraction to form a cyclopropyl radical, followed by a ring opening rearrangement and reaction with GSH. 3. These findings provided important information to the medicinal chemistry team which responded by replacing the cyclopropyl ring with a gem-dimethyl group. Subsequent compounds bearing this feature were shown to avert the bioactivation pathways in question. PMID- 29182425 TI - Endothelial alterations in a canine model of immune thrombocytopenia. AB - Bleeding heterogeneity amongst patients with immune thrombocytopenia (ITP) is poorly understood. Platelets play a role in maintaining endothelial integrity, and variable thrombocytopenia-induced endothelial changes may influence bleeding severity. Platelet-derived endothelial stabilizers and markers of endothelial integrity in ITP are largely underexplored. We hypothesized that, in a canine ITP model, thrombocytopenia would lead to alterations in the endothelial ultrastructure and that the Von Willebrand factor (vWF) would serve as a marker of endothelial injury associated with thrombocytopenia. Thrombocytopenia was induced in healthy dogs with an antiplatelet antibody infusion; control dogs received an isotype control antibody. Cutaneous biopsies were obtained prior to thrombocytopenia induction, at platelet nadir, 24 hours after nadir, and on platelet recovery. Cutaneous capillaries were assessed by electron microscopy for vessel thickness, the number of pinocytotic vesicles, the number of large vacuoles, and the number of gaps between cells. Pinocytotic vesicles are thought to represent an endothelial membrane reserve that can be used for repair of damaged endothelial cells. Plasma samples were assessed for vWF. ITP dogs had significantly decreased pinocytotic vesicle numbers compared to control dogs (P = 0.0357) and the increase in plasma vWF from baseline to 24 hours correlated directly with the endothelial large vacuole score (R = 0.99103; P < 0.0001). This direct correlation between plasma vWF and the number of large vacuoles, representing the vesiculo-vacuolar organelle (VVO), a permeability structure, suggests that circulating vWF could serve as a biomarker for endothelial alterations and potentially a predictor of thrombocytopenic bleeding. Overall, our results indicate that endothelial damage occurs in the canine ITP model and variability in the degree of endothelial damage may account for differences in the bleeding phenotype among patients with ITP. PMID- 29182426 TI - Effects of Single Set Resistance Training With Different Frequencies on a Cellular Health Indicator in Older Women. AB - The main purpose of this study was to compare the effects of resistance training (RT) performed two versus three times per week on phase angle (a cellular health indicator) in older women. A total of 39 women (69.1 +/- 5.5 years) were randomly assigned to perform a RT program two (G2X) or three (G3X) days per week for 12 weeks. The RT was a whole-body program (eight exercises, one set, 10-15 repetitions). Phase angle, resistance, reactance, and total body water were assessed by bioimpedance spectroscopy. Intracellular water, reactance, and phase angle increased significantly in G2X (2.1%, 3.0%, and 5.6%, respectively) and G3X (5.0%, 6.9%, and 10.3%, respectively) from pretraining to posttraining, with no significant difference between groups. Bioimpedance resistance decreased similarly in both groups (G2X = -1.7% vs. G3X = -3.2%). We conclude that a single set RT program with a frequency of 2 days per week may be sufficient to promote an improvement in cellular health in older women. PMID- 29182428 TI - O-Acetylation is essential for functional antibody generation against Staphylococcus aureus capsular polysaccharide. AB - Staphylococcus aureus produces an antiphagocytic polysaccharide capsule to evade neutrophil-mediated killing. Many vaccines against encapsulated bacterial pathogens require generation of functional anti-capsular antibodies to mediate protection against infection and disease. Here it is shown that the generation of such antibody responses to S. aureus in vivo and in vitro requires the presence of O-acetyl modifications on the capsular polysaccharides. O-acetylation of S. aureus capsular polysaccharide therefore should be monitored carefully during vaccine development and production. This finding may provide additional insight into the previous failure of a S. aureus capsular polysaccharide conjugate vaccine. PMID- 29182429 TI - The relationship between methylenetetrahydrofolate reductase C677T polymorphism and diabetic retinopathy: A meta-analysis in multiethnic groups. AB - BACKGROUND: Many studies have analyzed the association between methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and diabetic retinopathy (DR), however, the results remained inconclusive. We therefore aim to address this association by performing a meta-analysis in multiethnic groups. METHODS: Related studies were identified from PubMed and Chinese databases up to October 2016. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strength of the associations. RESULTS: A total of 20 studies including 1860 DR cases and 3646 controls were involved in this meta-analysis. In the overall population, we found that MTHFR C677T polymorphism was significantly associated with an increased risk of DR for each genetic model. In this meta analysis stratified by ethnicity, significantly increased risk of DR with the MTHFR C677T variants was found in the Chinese, Japanese, and Turks populations. CONCLUSIONS: Our study suggested that the MTHFR C677T polymorphism may contribute to DR development in multiethnic groups. Studies with larger sample sizes and wider spectrum of populations are warranted to verify this finding. PMID- 29182430 TI - On evaluation of consistency in multi-regional clinical trials. AB - In recent years, multi-regional clinical trials (MRCT) that conduct clinical trials simultaneously in Asian Pacific region, Europe, and the United States have become very popular for global pharmaceutical development. The main purpose of multi-regional clinical trials is to shorten the time for pharmaceutical development and regulatory submission, and approval around the world. In practice, however, clinical results observed from some regions (sub-population) may not be consistent with the results from other regions and/or all regions combined (entire population). The inconsistency observed may be due to ethnic differences in different regions, differences in medical practice, time points of assessment, or by random chance due to small sample size for the region. Some regional regulatory agencies require consistency evaluation between local country results and overall results. However, the challenge is there is no detailed guidance on the definition of 'consistency' and methodology to evaluate it. Therefore, the questions are: how to evaluate consistency and what statistical methods are appropriate to be used for consistency evaluation? In this article, several statistical tests for consistency (similarity) between clinical results observed from a specific sub-population and the entire population are proposed. These methods are compared through extensive simulation. As most published articles discussed consistency evaluation for superiority situations, we have discussed consistency evaluation for non-inferiority situation in this article through a simulated example concerning consistency in some countries. Recommendations of the statistical methods to be used for consistency evaluation are given. Other aspects that should be considered for consistency evaluation are also provided. PMID- 29182431 TI - Impact-Induced Muscle Damage and Contact Sports: Etiology, Effects on Neuromuscular Function and Recovery, and the Modulating Effects of Adaptation and Recovery Strategies. AB - Athletes involved in contact sports are habitually exposed to skeletal-muscle damage in their training and performance environments. This often leads to exercise-induced muscle damage (EIMD) resulting from repeated eccentric and/or high-intensity exercise and to impact-induced muscle damage (IIMD) resulting from collisions with opponents and the playing surface. While EIMD has been an area of extensive investigation, IIMD has received comparatively little research, with the magnitude and time frame of alterations following IIMD not presently well understood. It is currently thought that EIMD results from an overload of mechanical stress that causes ultrastructural damage to the cellular membrane constituents. Damage leads to compromised ability to produce force, which manifests immediately and persists for up to 14 d following exercise exposure. IIMD has been implicated in attenuated neuromuscular performance and recovery and in inflammatory processes, although the underlying course over time remains unclear. Exposure to EIMD leads to an adaptation to subsequent exposures, a phenomenon known as the repeated-bout effect. An analogous adaptation has been suggested to occur following IIMD; however, to date, this contention remains equivocal. While a considerable body of research has explored the efficacy of recovery strategies following EIMD, strategies promoting recovery from IIMD are limited to investigations using animal contusion models. Strategies such as cryotherapy and antioxidant supplementation that focus on attenuating the secondary inflammatory response may provide additional benefit in IIMD and are explored herein. Further research is required to first establish a model of generating IIMD and then explore broader areas around IIMD in athletic populations. PMID- 29182432 TI - Temporal Consistency and Movement Effort of Repetitive Reaching During Continuation in Children and Adults. AB - The ability to match one's movements to an external beat and maintain that rhythm in the absence of the beat suggests sophisticated, well-developed neural control. Children (aged 5-10 years) were compared with adults (aged 18-30 years) during a repetitive reaching task to determine development of this control. Children as young as 5 years exhibited this control. The mean rate of reaching did not differ between groups nor did it differ during the two phases, suggesting an overall ability to internalize and continuously repeat a given pace. Children aged 5-8 years were significantly more variable than children aged 9-10 years and adults, likely attributable to variability in central control processes. We found a possible transition period of temporal control. Children aged 9-10 years begin to exhibit more adult-like levels of variability with respect to temporal consistency and movement effort. PMID- 29182433 TI - An Experimental Method to Estimate Upper Limbs Inertial Parameters During Handcycling. AB - This study proposes an experimental method to estimate personalized inertial parameters of upper limbs during handcycling by using a planar dynamic model. The handle forces are expressed as a product of a matrix describing the kinematics terms and a vector of inertial parameters of arm and forearm. The parameters are estimated by measuring the handle forces during a suitable "passive test" and inverting the mentioned matrix. The data were acquired while an operator actuated the handle and the subject's muscles were relaxed. To validate the estimation procedure, it was applied to a custom-made artificial arm mechanism, and the results were compared with its known parameters. The method was then used to estimate the inertial parameters of 6 human subjects. The estimated parameters were used to compute the exchanged forces and compared with the measured ones obtaining an average error of 14% both for Fx and Fy. These errors are significantly smaller than those obtained using dynamic parameters extracted from the literature to compute the forces, which were 50% for Fx and 19% for Fy. An individual evaluation of inertial parameters better describes interaction forces during handcycling, especially for subjects whose body structures are different from the average population. PMID- 29182434 TI - Reactive Strength Index: A Poor Indicator of Reactive Strength? AB - PURPOSE: To assess the relationships between reactive strength measures and associated kinematic and kinetic performance variables achieved during drop jumps. A secondary aim was to highlight issues with the use of reactive strength measures as performance indicators. METHODS: Twenty-eight national- and international-level sprinters, 14 men and 14 women, participated in this cross sectional analysis. Athletes performed drop jumps from a 0.3-m box onto a force platform with dependent variables contact time (CT), landing time, push-off time, flight time, jump height (JH), reactive strength index (RSI, calculated as JH/CT), reactive strength ratio (RSR, calculated as flight time/CT), and vertical leg-spring stiffness recorded. RESULTS: A Pearson correlation test found very high to near-perfect relationships between RSI and RSR (r = .91-.97), with mixed relationships between RSI, RSR, and the key performance variables (men: r = -.86 to -.71 between RSI/RSR and CT, r = .80-.92 between RSI/RSR and JH; women: r = .85 to -.56 between RSR and CT, r = .71 between RSI and JH). CONCLUSIONS: The method of assessing reactive strength (RSI vs RSR) may be influenced by the performance strategies adopted, that is, whether athletes achieve their best reactive strength scores via low CTs, high JHs, or a combination. Coaches are advised to limit the variability in performance strategies by implementing upper and/or lower CT thresholds to accurately compare performances between individuals. PMID- 29182435 TI - Racial and Ethnic Differences in Mental Health among Asian Americans and Non Hispanic Whites: Based on California Health Interview Survey. AB - While Asians are becoming the largest ethnic group in the United States, studies have focused on Asians as a single population. The purpose of this study was to explore the racial and ethnic mental health differences between non-Hispanic Whites and Asians, with an emphasis on understudied subgroups, from the California Health Interview Survey 2011/2012. In this dataset Asians had significantly lower adjusted odds ratios for both mental distress and serious mental illness. However, when Asians were divided into subgroups and compared to Whites, Vietnamese and Japanese subgroups were significantly lower than Whites for mental distress while Koreans were significantly higher. Vietnamese and Chinese were found to have significantly less serious mental illness than Whites in the subgroup analyses. Our results underscore the importance of recognizing that Asian subgroups should not be overlooked, and all Asians should not automatically be treated as a homogenous group. PMID- 29182436 TI - Vertical and Horizontal Jump Capacity in International Cerebral Palsy Football Players. AB - PURPOSE: To evaluate the reliability and validity of vertical and horizontal jump tests in football players with cerebral palsy (FPCP) and to analyze the jump performance differences between current International Federation for Cerebral Palsy Football functional classes (ie, FT5-FT8). METHODS: A total of 132 international parafootballers (25.8 [6.7] y; 70.0 [9.1] kg; 175.7 [7.3] cm; 22.8 [2.8] kg.m-2; and 10.7 [7.5] y training experience) participated in the study. The participants were classified according to the International Federation for Cerebral Palsy Football classification rules, and a group of 39 players without cerebral palsy was included in the study as a control group. Football players' vertical and horizontal jump performance was assessed. RESULTS: All the tests showed good to excellent relative intrasession reliability scores, both in FPCP and in the control group (intraclass correlation = .78-.97, SEM < 10.5%). Significant between-groups differences (P < .001) were obtained in the countermovement jump, standing broad jump, 4 bounds for distance, and triple hop for distance dominant leg and nondominant leg. The control group performed higher/farther jumps with regard to all the FPCP classes, obtaining significant differences and moderate to large effect sizes (ESs) (.85 < ES < 5.54, P < .01). Players in FT8 class (less severe impairments) had significantly higher scores in all the jump tests than players in the lower classes (ES = moderate to large, P < .01). CONCLUSIONS: The vertical and horizontal jump tests performed in this study could be applied to the classification procedures and protocols for FPCP. PMID- 29182437 TI - Immunotherapy for pet allergies. AB - Allergic diseases compose a serious challenge for modern societies. Their individual, medical and economical burden is large. As humans spend most of their time indoors, exposure to indoor allergens is a significant contributor to the development of allergic sensitization and respiratory allergies, such as allergic rhinoconjunctivitis and asthma. One important source of indoor allergens are pets, in particular cats and dogs. Allergens from these and other mammals spread effectively and they are encountered widely in public places. If patient education, allergen avoidance and pharmacotherapy do not suffice for controlling the symptoms of pet allergy, allergen immunotherapy can be a treatment option. Current information on allergen immunotherapy in pet allergy suggests that it can be effective in reducing allergic symptoms. However, the low number of high quality randomized controlled trials of allergen immunotherapy in pet allergy warrants for further investigations. PMID- 29182438 TI - High numbers of myeloid derived suppressor cells in peripheral blood and ascitic fluid of cirrhotic and HCC patients. AB - BACKGROUND: Hepatocellular carcinoma (HCC) is the 3rd most common cause of cancer related death worldwide. It has evolved different immune escape mechanisms, which might include emergence of lymphoid and myeloid regulatory cells. Aim of this work: To determine the numbers of Myeloid-derived suppressor cells (MDSCs) in peripheral blood and ascitic fluid in cirrhosis and HCC and their relation to IFN gamma and alpha-fetoprotein (alpha-FP). PATIENTS AND METHODS: Sixty individuals were enrolled in this study; forty cirrhotic patients with ascites; twenty without HCC (Group I), and twenty with HCC (group II) as well as twenty healthy individuals as a control group (group III). The phenotype and numbers of MDSCs were analyzed in peripheral blood of all the individuals and ascitic fluid of the patients using flow cytometry. Intracellular IFN-gamma and serum alfa-fetoprotein were measured. RESULTS: Significant increases in the relative and the mean number of peripheral blood MDSCs were found in the cirrhosis and HCC groups than in the control group, with the HCC group showing the highest number. MDSC count was negatively correlated with IFN-gamma levels, while alpha-FP was positively correlated with MDSC% in the HCC group. MDSC count was low in ascitic fluid of both HCC and cirrhosis groups with no significant difference between the 2 groups. CONCLUSION: A high frequency of MDSCs was detected in the peripheral blood of cirrhotic and HCC patients, indicating presence of immunosuppressive arms. These cells could be targeted to develop a new effective immunotherapy or an adjuvant to current therapies. PMID- 29182440 TI - The Action Level. PMID- 29182439 TI - Chondrocyte-based intraoperative processing strategies for the biological augmentation of a polyurethane meniscus replacement. AB - : Purpose/aim of study: Menisectomies account for over 1.5 million surgical interventions in Europe annually, and there is a growing interest in regenerative strategies to improve outcomes in meniscal replacement. The overall objective of this study was to evaluate the role of intraoperatively applied fresh chondrocyte (FC) isolates compared to minced cartilage (MC) fragments, used without cell isolation, to improve bioactivity and tissue integration when combined with a polyurethane replacement. MATERIALS AND METHODS: First, to optimize the intraoperative cell isolation protocol, caprine articular cartilage biopsies were digested with 750 U/ml or 3000 U/ml collagenase type II (ratio of 10 ml per g of tissue) for 30 min, 1 h or 12 h with constant agitation and compared to culture expanded chondrocytes in terms of matrix deposition when cultured on polyurethane scaffolds. Finally, FCs and MC-augmented polyurethane scaffolds were evaluated in a caprine meniscal explant model to assess the potential enhancements on tissue integration strength. RESULTS: Adequate numbers of FCs were harvested using a 30 min chondrocyte isolation protocol and were found to demonstrate improved matrix deposition compared to standard culture-expanded cells in vitro. Upon evaluation in a meniscus explant defect model, both FCs and MC showed improved matrix deposition at the tissue-scaffold interface and enhanced push-out strength, fourfold and 2.5-fold, respectively, compared with the acellular implant. CONCLUSIONS: Herein, we have demonstrated a novel approach that could be applied intraoperatively, using FCs or MC for improved tissue integration with a polyurethane meniscal replacement. PMID- 29182444 TI - Performance validity testing in neuropsychology: a clinical guide, critical review, and update on a rapidly evolving literature. AB - OBJECTIVE: Over the past two decades, there has been much research on measures of response bias and myriad measures have been validated in a variety of clinical and research samples. This critical review aims to guide clinicians through the use of performance validity tests (PVTs) from test selection and administration through test interpretation and feedback. METHOD/RESULTS: Recommended cutoffs and relevant test operating characteristics are presented. Other important issues to consider during test selection, administration, interpretation, and feedback are discussed including order effects, coaching, impact on test data, and methods to combine measures and improve predictive power. When interpreting performance validity measures, neuropsychologists must use particular caution in cases of dementia, low intelligence, English as a second language/minority cultures, or low education. CONCLUSIONS: PVTs provide valuable information regarding response bias and, under the right circumstances, can provide excellent evidence of response bias. Only after consideration of the entire clinical picture, including validity test performance, can concrete determinations regarding the validity of test data be made. PMID- 29182441 TI - Elimination of tumor by CD47/PD-L1 dual-targeting fusion protein that engages innate and adaptive immune responses. AB - The host immune system generally serves as a barrier against tumor formation. Programmed death-ligand 1 (PD-L1) is a critical "don't find me" signal to the adaptive immune system, whereas CD47 transmits an anti-phagocytic signal, known as the "don't eat me" signal, to the innate immune system. These and similar immune checkpoints are often overexpressed on human tumors. Thus, dual targeting both innate and adaptive immune checkpoints would likely maximize anti-tumor therapeutic effect and elicit more durable responses. Herein, based on the variable region of atezolizumab and consensus variant 1 (CV1) monomer, we constructed a dual-targeting fusion protein targeting both CD47 and PD-L1 using "Knobs-into-holes" technology, denoted as IAB. It was effective in inducing phagocytosis of tumor cells, stimulating T-cell activation and mediating antibody dependent cell-mediated cytotoxicity in vitro. No obvious sign of hematological toxicity was observed in mice administered IAB at a dose of 100 mg/kg, and IAB exhibited potent antitumor activity in an immune-competent mouse model of MC38. Additionally, the anti-tumor effect of IAB was impaired by anti-CD8 antibody or clodronate liposomes, which implied that both CD8+ T cells and macrophages were required for the anti-tumor efficacy of IAB and IAB plays an essential role in the engagement of innate and adaptive immune responses. Collectively, these results demonstrate the capacity of an elicited endogenous immune response against tumors and elucidate essential characteristics of synergistic innate and adaptive immune response, and indicate dual blockade of CD47 and PD-L1 by IAB may be a synergistic therapy that activates both innate and adaptive immune response against tumors.

AB - OBJECTIVES: To investigate the factor structure of financial capacity using a direct-performance measure of financial skills (The Financial Capacity Instrument [FCI]) as a proxy for the financial capacity construct. METHODS: The study sample was composed of 440 older adults who represented the cognitive spectrum from normal cognitive aging to mild cognitive impairment (MCI) to mild dementia: 179 healthy older adults, 149 participants with MCI, and 112 participants with mild Alzheimer's dementia (AD). RESULTS: Both Velicer's Minimum Average Partial test and Horn's parallel analysis supported a four-factor solution which accounted for 46% of variance. The four extracted factors were interpreted as: (1) Basic Monetary Knowledge and Calculation Skills, (2) Financial Judgment, (3) Financial Conceptual Knowledge, and (4) Financial Procedural Knowledge. CONCLUSIONS: The study findings represent an important first step in empirically articulating the financial capacity construct in aging. The four identified factors can guide both clinical practice and future instrument utilization and development. CLINICAL IMPLICATIONS: Cognitively impaired older adults with MCI and mild AD dementia are likely to show financial changes in one or more of the four identified financial factors. Clinicians working with older adults should routinely examine for potential changes in these four areas of financial function. PMID- 29182445 TI - Attractiveness as a Function of Skin Tone and Facial Features: Evidence from Categorization Studies. AB - Participants rated the attractiveness and racial typicality of male faces varying in their facial features from Afrocentric to Eurocentric and in skin tone from dark to light in two experiments. Experiment 1 provided evidence that facial features and skin tone have an interactive effect on perceptions of attractiveness and mixed-race faces are perceived as more attractive than single race faces. Experiment 2 further confirmed that faces with medium levels of skin tone and facial features are perceived as more attractive than faces with extreme levels of these factors. Black phenotypes (combinations of dark skin tone and Afrocentric facial features) were rated as more attractive than White phenotypes (combinations of light skin tone and Eurocentric facial features); ambiguous faces (combinations of Afrocentric and Eurocentric physiognomy) with medium levels of skin tone were rated as the most attractive in Experiment 2. Perceptions of attractiveness were relatively independent of racial categorization in both experiments.

AB - The rise of the popular Internet has coincided with the increasing acceptance, even assimilation, of lesbians into mainstream society. The visible presence of lesbians in the tech industry and in digitally mediated spaces raises a set of questions about the relationship between queer identities and Internet technologies. This introduction to a special issue of Journal of Lesbian Studies explores some of these questions and provides an overview of the articles that follow.

PMID- 29182448 TI - Cerebrospinal Fluid Cytokine Expression Profile in Multiple Sclerosis and Chronic Inflammatory Demyelinating Polyneuropathy. AB - BACKGROUND: Cerebrospinal fluid (CSF) analysis in patients with particular neurologic disorders is a powerful tool to evaluate specific central nervous system inflammatory markers for diagnostic needs, because CSF represents the specific immune micro-environment to the central nervous system. METHODS: CSF samples from 49 patients with multiple sclerosis (MS), chronic inflammatory demyelinating polyneuropathy (CIDP), and non-inflammatory neurologic disorders (NIND) as controls were submitted to protein expression profiles of 47 inflammatory biomarkers by multiplex Luminex bead assay to investigate possible differences in the inflammatory process for MS and CIDP. RESULTS: Our results showed differences in CSF cytokine levels in MS and CIDP; in particular, IL12 (p40) was significantly highly expressed in MS in comparison with CIDP and NIND, while SDF-1alpha and SCGF-beta were significantly highly expressed in CIDP cohort when compared to MS and NIND. IL-9, IL-13, and IL-17 had higher expression levels in NIND if compared with the other groups. CONCLUSIONS: Our study showed that, despite some common pathogenic mechanisms, central and peripheral nervous system demyelinating diseases, such as MS and CIDP, differ in some specific inflammatory soluble proteins in CSF, underlining differences in the immune response involved in those autoimmune diseases.

AB - AIM: The present study explored the gender interaction on the risk of uric acid in the new development of hypertension. STUDY DESIGN: A longitudinal retrospective cohort. SUBJECTS & METHODS: A total of 5,807 individuals with an average age of 38 +/- 7 years old were recruited. Individuals whose blood pressure rose more than 140/90mmHg or those who newly commenced antihypertensive treatment were defined as a new onset of hypertension. Cox regression analysis was employed for the analysis. RESULTS: During the 10-years follow-up, 42.8% of men and 22.2% of women had developed hypertension. Factors to predict the hypertension development were male gender, older age, higher BMI, higher uric acid, and higher mean blood pressure. An association between higher uric acid levels and higher incidence of hypertension remained statistically significant in women in a multivariate model adjusted for various clinical variables (Hazard ration (HR), 1.180; 95%CI, 1.018 to 1.369), whereas such association was not found in men (HR, 1.034; 95%CI, 0.994 to 1.075). The interaction between the two genders reached statistical significance (p for interaction = 0.007). CONCLUSION: Higher uric acid is associated with the incident hypertension in the both genders. Women are more susceptible to the development of hypertension than men. PMID- 29182451 TI - Protein Recommendations for Weight Loss in Elite Athletes: A Focus on Body Composition and Performance. AB - There exists a large body of scientific evidence to support protein intakes in excess of the recommended dietary allowance (RDA) (0.8 g protein/kg/day) to promote the retention of skeletal muscle and loss of adipose tissue during dietary energy restriction. Diet-induced weight loss with as low as possible ratio of skeletal muscle to fat mass loss is a situation we refer to as high quality weight loss. We propose that high-quality weight loss is often of importance to elite athletes in order to maintain their muscle (engine) and shed unwanted fat mass, potentially improving athletic performance. Current recommendations for protein intakes during weight loss in athletes are set at 1.6 2.4 g protein/kg/day. However, the severity of the caloric deficit and type and intensity of training performed by the athlete will influence at what end of this range athletes choose to be. Other considerations regarding protein intake that may help elite athletes achieve weight loss goals include the quality of protein consumed, and the timing and distribution of protein intake throughout the day. This review highlights the scientific evidence used to support protein recommendations for high-quality weight loss and preservation of performance in athletes. Additionally, the current knowledge surrounding the use of protein supplements, branched chain amino acids (BCAA), beta-hydroxy beta-methylbutyrate (HMB), and other dietary supplements with weight loss claims will be discussed. PMID- 29182452 TI - Exome Array Analysis of Nuclear Lens Opacity. AB - PURPOSE: Nuclear cataract is the most common subtype of age-related cataract, the leading cause of blindness worldwide. It results from advanced nuclear sclerosis, or opacity in the center of the optic lens, and is affected by both genetic and environmental risk factors, including smoking. We sought to understand the genetic factors associated with nuclear sclerosis through interrogation of rare and low frequency coding variants using exome array data. METHODS: We analyzed Illumina Human Exome Array data for 1,488 participants of European ancestry in the Beaver Dam Eye Study who were without cataract surgery for association with nuclear sclerosis grade, controlling for age and sex. We performed single-variant regression analysis for 32,138 variants with minor allele frequency (MAF) >=0.003. In addition, gene-based analysis of 11,844 genes containing at least two variants with MAF < 0.05 was performed using a gene-based unified burden and non burden sequence kernel association test (SKAT-O). Additionally, both single variant and gene-based analyses were analyzed stratified by smoking status. RESULTS: No single-variant test was statistically significant after Bonferroni correction (p < 1.6 * 10-6; top single nucleotide polymorphism (SNP): rs144458991, p = 2.83 * 10-5). Gene-based tests were suggestively associated with the gene RNF149 overall (p = 8.29 * 10-6) and among never smokers (N = 790, p = 2.67 * 10-6). CONCLUSIONS: This study did not find a significant genetic association with nuclear sclerosis, the possible association with the RNF149 gene highlights a potential candidate gene for future studies that aim to understand the genetic architecture of nuclear sclerosis. PMID- 29182453 TI - Women outperform men in distinguishing between authentic and nonauthentic smiles. AB - Women tend to be more accurate in decoding facial expressions than men. We hypothesized that women's better performance in decoding facial expressions extends to distinguishing between authentic and nonauthentic smiles. We showed participants portrait photos of persons who smiled because either they saw a pleasant picture (authentic smile) or were instructed to smile by the experimenter (nonauthentic smile) and asked them to identify the smiles. Participants judged single photos of persons depicting either an authentic or a nonauthentic smile, and they judged adjacent photos of the same person depicting an authentic smile and a nonauthentic smile. Women outperformed men in identifying the smiles when judging the adjacent photos. We discuss implications for judging smile authenticity in real life and limitations for the observed sex difference.

PMID- 29182456 TI - Levels of oxidative damage and proinflammatory cytokines are enhanced in patients with active vitiligo. AB - Vitiligo is an autoimmune depigmenting skin disease characterised by loss of melanocytes wherein oxidative stress is proposed to be the initial triggering factor with subsequent immune dysregulation. This study aimed to evaluate the relationship, if any, between the generation of reactive oxygen species (ROS), markers of oxidative damage and circulating cytokines in patients with active vitiligo. The generation of ROS in erythrocytes and neutrophils was significantly higher in patients with active vitiligo than healthy controls. Alongside, markers of oxidative stress-mediated damage namely lipid peroxidation, DNA damage and protein carbonylation were evaluated. Patients with active vitiligo demonstrated increased lipid and DNA damage but minimal protein damage. There was a significant decline in the free radical scavenging capacity of active vitiligo cases. A positive correlation existed between baseline levels of ROS and lipid peroxidation as also DNA damage. Patients with active vitiligo demonstrated an increase in several proinflammatory (IL-6, TNF-alpha, IL-1beta, IFN-gamma and IL 8) and some anti-inflammatory/immunoregulatory (IL-5 and IL-10) cytokines. Importantly, the levels of IFN-gamma and IL-10 consistently correlated with the generation of ROS, markers of damage and their free radical scavenging capacity. Taken together, patients with active vitiligo demonstrated an enhanced generation of ROS in erythrocytes and neutrophils which mediated lipid peroxidation, DNA damage and coupled with a decline in their antioxidant capacity created a pro oxidant milieu that favoured tissue damage and potential generation of neoantigens, accounting for disease progression. PMID- 29182455 TI - Isolation of blood-brain barrier-crossing antibodies from a phage display library by competitive elution and their ability to penetrate the central nervous system. AB - The blood-brain barrier (BBB) is a formidable obstacle for delivery of biologic therapeutics to central nervous system (CNS) targets. Whilst the BBB prevents passage of the vast majority of molecules, it also selectively transports a wide variety of molecules required to maintain brain homeostasis. Receptor-mediated transcytosis is one example of a macromolecule transport system that is employed by cells of the BBB to supply essential proteins to the brain and which can be utilized to deliver biologic payloads, such as antibodies, across the BBB. In this study, we performed phage display selections on the mouse brain endothelial cell line, bEND.3, to enrich for antibody single-chain variable fragments (scFvs) that could compete for binding with a known BBB-crossing antibody fragment, FC5. A number of these scFvs were converted to IgGs and characterized for their ability to bind to mouse, rat and human brain endothelial cells, and subsequent ability to transport across the BBB. We demonstrated that these newly identified BBB-targeting IgGs had increased brain exposure when delivered peripherally in mice and were also able to transport a biologically active molecule, interleukin 1 receptor antagonist (IL-1RA), into the CNS. The antagonism of the interleukin-1 system within the CNS can result in the relief of neuropathic pain. We demonstrated that the BBB-targeting IgGs were able to elicit an analgesic response in a mouse model of nerve ligation-induced hypersensitivity when fused to IL-1RA. PMID- 29182457 TI - A Comparison of the Isometric Midthigh Pull and Isometric Squat: Intraday Reliability, Usefulness, and the Magnitude of Difference Between Tests. AB - PURPOSE: To examine the reliability and usefulness of the isometric midthigh pull (IMTP) and isometric squat (ISqT) performed at the same knee and hip angles. The scores produced in each test were compared to determine the magnitude of differences between tests. METHODS: Twenty-six male and female athletes (age, 23.6 [4.3] y; height, 1.75 [0.07] m; and body mass, 68.8 [9.7] kg) performed 2 maximal repetitions of the IMTP and ISqT following a specific warm-up. RESULTS: Maximum force, absolute peak force (PF), relative PF, allometrically scaled PF, rate of force development (0-200 and 0-250 ms), and impulse (0-300 ms) were deemed reliable (intraclass correlation coefficient [ICC] >=.86 and coefficient of variation [CV] <=9.4%) in the IMTP and ISqT based on predetermined criteria (ICC >=.8 and CV <=10%). Impulse (0-200 and 0-250 ms) was reliable in the ISqT (ICC >=.92 and CV <=9.9%). Participants produced significantly (P < .05) greater PF and impulse (0-300 ms) during the ISqT compared with the IMTP. When split by sex, female participants produced significantly greater PF (P = .042) during the ISqT, with no significant differences among male participants (P = .245). Both tests are capable of detecting changes in performance in maximum force and absolute PF. CONCLUSIONS: Both tests are reliable for non-time-dependent maximal strength measures when measured at the same knee and hip angles. The ISqT may be preferred when coaches want to test an athlete's true maximum lower-limb strength, especially female athletes. PMID- 29182459 TI - Recurrent pityriasis rosea: A case report. AB - Pityriasis rosea is a papulosquamous skin disorder that occurs most commonly between the ages of 10 and 35 years. Recurrent pityriasis rosea is rare. We report a patient suffering from recurrent pityriasis rosea, whose etiology may be related to either vaccine-induced stimulation of the immune system, or some rare vaccine component(influenza A [H1N1] vaccine, hepatitis B vaccine). We believe that such a case is unique and it has not been reported previously. The patient was successfully treated with a combination of oral cetirizine, a topical steroid cream, and narrowband-ultraviolet B phototherapy. The symptoms of this disorder should be recognized by dermatologists. PMID- 29182460 TI - Balance and Mobility Training With or Without Simultaneous Cognitive Training Reduces Attention Demand But Does Not Improve Obstacle Clearance in Older Adults. AB - The purpose of this study was to determine whether balance and mobility training (BMT) or balance and mobility plus cognitive training (BMT + C) would improve obstacle clearance and reaction time (RT); whether further improvements would be exposed in the BMT + C group relative to the BMT group; and whether possible improvements would be sustained at the follow-up. Healthy older adults were allocated to the BMT (n = 15; age: 70.2 +/- 3.2), BMT + C (n = 14; age: 68.7 +/- 5.5), or control group (n = 13; age: 66.7 +/- 4.2). The BMT and BMT + C groups trained one-on-one, three times per week for 12 weeks on a balance obstacle course. The BMT + C group also completed cognitive training. Participants walked onto and over six obstacles of varying heights while completing no RT, simple RT, and choice RT tasks at baseline, posttraining, and at the 12-week follow-up. Both the BMT and BMT + C groups improved RT and maintained these improvements at the follow-up. No meaningful improvements in obstacle clearance emerged following training. Thus, dual-task balance training likely reduces attention demand. PMID- 29182461 TI - Diagnosis of multiple endocrine neoplasia type 2B and management of its ocular features. AB - BACKGROUND: To describe ocular and vascular findings in a patient with multiple endocrine neoplasia type 2B. MATERIALS AND METHODS: Case report of a 31-year-old male who was referred for ocular assessment following diagnosis of a carotid artery dissection and multiple vascular anomalies. RESULTS: Clinical examination revealed a marfanoid habitus, myelinated corneal nerve fibers, neuromas in the perilimbal area, conjunctival hyperemia with peripheral corneal neovascularization, and posterior blepharitis. Diagnosis of multiple endocrine neoplasia type 2B was confirmed by genetic testing of the RET proto-oncogene. Genetic screening for hereditary aortic and peripheral vasculopathies failed to reveal an underlying cause for the vascular findings. We noted improvement of the ocular surface disease with topical corticosteroids and oral tetracyclines. CONCLUSIONS: Ophthalmologists play a vital role in recognizing this rare but lethal malignancy. We report on a patient with apart from characteristic ocular findings also staphylococcal hypersensitivity and widespread systemic vasculopathy. PMID- 29182458 TI - Multimedia Aided Consent for Alzheimer's Disease Research. AB - OBJECTIVES: Optimizing the research consent process simultaneously fosters respect for autonomy and protection of those with diminished capacity for autonomy. This study evaluated the effectiveness of an enhanced research consent procedure, employing multimedia disclosure and corrective feedback, in improving decisional capacity among 114 people with mild-to-moderate Alzheimer's disease (AD) and 134 non-psychiatric comparison (NC) subjects. METHODS: Participants were randomized to consent type (routine versus enhanced) and protocol type (lower versus higher risk). Outcomes included a 5-item questionnaire assessing immediate comprehension, MacArthur Competence Assessment Tool for Clinical Research assessing four components of decision-making capacity, and categorical decisional capacity (based on a cut-score established in reference to expert judgments for a subset of participants). RESULTS: There was no significant effect of the enhanced consent procedure, relative to routine consent, on immediate comprehension or decisional capacity. CONCLUSIONS: Multimedia tools do not appear to be the solution to better consent for AD research. CLINICAL IMPLICATIONS: Given the ethical primacy of informed consent and issues of justice for impaired populations who might be harmed by an absence of research-based treatment advances, continued search for ways to more meaningfully engage people with AD in the consent or assent process is warranted. PMID- 29182463 TI - Willingness to pay for cataract surgery is much lower than actual costs in Zamfara state, northern Nigeria. AB - PURPOSE: Direct medical and non-medical costs incurred by those undergoing subsidised cataract surgery at Gusau eye clinic, Zamfara state, were recently determined. The aim of this study was to assess the willingness to pay for cataract surgery among adults with severe visual impairment or blindness from cataract in rural Zamfara and to compare this to actual costs. METHODS: In three rural villages served by Gusau eye clinic, key informants helped identify 80 adults with bilateral severe visual impairment or blindness (<6/60), with cataract being the cause in at least one eye. The median amount participants were willing to pay for cataract surgery was determined. The proportion willing to pay actual costs of the (i) subsidised surgical fee (US$18.5), (ii) average non medical expenses (US$25.2), and (iii) average total expenses (US$51.2) at Gusau eye clinic were calculated. Where participants would seek funds for surgery was determined. RESULTS: Among 80 participants (38% women), most (n = 73, 91%) were willing to pay something, ranging from 80%) and moderate/severe lung disease (FEV1 <80%). Results Of the 181 patients reviewed, 131 with primary FESS had FEV1 data. Presurgery average age was 16 years (95% confidence interval [CI], 14.27-17.73), and FEV1 mean was 85% (95% CI, 81.02 88.98). There were 88 patients with FEV1 >80% and 43 patients with FEV1 <80%. For the entire cohort, lung function did not change related to FESS. Among patients with FEV1 <80%, FEV1 declined presurgery by 3.5% per year (95% CI, -6.1% to 0.8%; P = .010), which halted after surgery with these patients, then showing no subsequent change in FEV1 (95% CI, 0.9%-3.7%; P = .240). No benefit was identified for patients with FEV1 >80%. Conclusion Pulmonary function testing improved in patients with moderate/severe lung disease 1 year following FESS. This suggests FESS may benefit pulmonary outcomes. PMID- 29182492 TI - Platelet Transfusion for Patients With Cancer: American Society of Clinical Oncology Clinical Practice Guideline Update Summary. PMID- 29182493 TI - Japan's 2014 General Election: Political Bots, Right-Wing Internet Activism, and Prime Minister Shinzo Abe's Hidden Nationalist Agenda. AB - In this article, we present results on the identification and behavioral analysis of social bots in a sample of 542,584 Tweets, collected before and after Japan's 2014 general election. Typical forms of bot activity include massive Retweeting and repeated posting of (nearly) the same message, sometimes used in combination. We focus on the second method and present (1) a case study on several patterns of bot activity, (2) methodological considerations on the automatic identification of such patterns and the prerequisite near-duplicate detection, and (3) we give qualitative insights into the purposes behind the usage of social/political bots. We argue that it was in the latency of the semi-public sphere of social media-and not in the visible or manifest public sphere (official campaign platform, mass media)-where Shinzo Abe's hidden nationalist agenda interlocked and overlapped with the one propagated by organizations such as Nippon Kaigi and Internet right wingers (netto uyo) during the election campaign, the latter potentially forming an enormous online support army of Abe's agenda. PMID- 29182494 TI - Food Insecurity and Obesity: Exploring the Role of Social Support. AB - BACKGROUND: Women are disproportionately affected by both obesity and food insecurity. Food insecurity occurs when there is limited ability to acquire adequate foods. It is unknown whether social support can reduce the effect of food insecurity on increased obesity. This study seeks to determine whether social support modifies the relationship between food insecurity and obesity. METHODS: We conducted a cross-sectional study in a nationally representative sample of 4672 women aged >=40 years using National Health and Nutrition Examination Survey (2003-2008). Individual food insecurity was assessed based on the U.S. Department of Agriculture 18-item validated household food security scale. Women were categorized as fully food secure (0 affirmative responses) or food insecure (1-10 affirmative responses). Obesity was defined as body mass index >=30 kg/m2. Outcomes were analyzed by multivariable logistic regression. RESULTS: Fourteen percent were food insecure. Women with food insecurity had 1.4 the odds of obesity as those who were fully food secure, adjusting for race/ethnicity and health status (95% confidence interval [CI] 1.22-1.62). Food insecure women were 80% less likely to report strong social support than women who were fully food secure (95% CI 0.11-0.36). Social support as measured in this study did not modify the association between food insecurity and obesity. CONCLUSIONS: Women reporting food insecurity reported lower levels of social support and were more likely to experience obesity. Interventions to reduce obesity in women who are food insecure must consider the limited resources available to these women. PMID- 29182495 TI - Platelet Transfusion for Patients With Cancer: American Society of Clinical Oncology Clinical Practice Guideline Update. AB - Purpose To provide evidence-based guidance on the use of platelet transfusion in people with cancer. This guideline updates and replaces the previous ASCO platelet transfusion guideline published initially in 2001. Methods ASCO convened an Expert Panel and conducted a systematic review of the medical literature published from September 1, 2014, through October 26, 2016. This review builds on two 2015 systematic reviews that were conducted by the AABB and the International Collaboration for Transfusion Medicine Guidelines. For clinical questions that were not addressed by the AABB and the International Collaboration for Transfusion Medicine Guidelines (the use of leukoreduction and platelet transfusion in solid tumors or chronic, stable severe thrombocytopenia) or that were addressed partially (invasive procedures), the ASCO search extended back to January 2000. Results The updated ASCO review included 24 more recent publications: three clinical practice guidelines, eight systematic reviews, and 13 observational studies. Recommendations The most substantial change to a previous recommendation involved platelet transfusion in the setting of hematopoietic stem-cell transplantation. Based on data from randomized controlled trials, adult patients who undergo autologous stem-cell transplantation at experienced centers may receive a platelet transfusion at the first sign of bleeding, rather than prophylactically. Prophylactic platelet transfusion at defined platelet count thresholds is still recommended for pediatric patients undergoing autologous stem-cell transplantation and for adult and pediatric patients undergoing allogeneic stem-cell transplantation. Other recommendations address platelet transfusion in patients with hematologic malignancies or solid tumors or in those who undergo invasive procedures. Guidance is also provided regarding the production of platelet products, prevention of Rh alloimmunization, and management of refractoriness to platelet transfusion ( www.asco.org/supportive-care-guidelines and www.asco.org/guidelineswiki ). PMID- 29182496 TI - Phase II Study of BGJ398 in Patients With FGFR-Altered Advanced Cholangiocarcinoma. AB - Purpose No standard treatment exists for patients with cholangiocarcinoma for whom first-line gemcitabine-based therapy fails. Fibroblast growth factor receptor 2 ( FGFR2) fusions/translocations are present in 13% to 17% of intrahepatic cholangiocarcinomas. BGJ398, an orally bioavailable, selective pan FGFR kinase inhibitor, has shown preliminary clinical activity against tumors with FGFR alterations. Methods A multicenter, open-label, phase II study ( ClinicalTrials.gov identifier: NCT02150967) evaluated BGJ398 antitumor activity in patients age >= 18 years with advanced or metastatic cholangiocarcinoma containing FGFR2 fusions or other FGFR alterations whose disease had progressed while receiving prior therapy. Patients received BGJ398 125 mg once daily for 21 days, then 7 days off (28-day cycles). The primary end point was investigator assessed overall response rate. Results Sixty-one patients (35 women; median age, 57 years) with FGFR2 fusion (n = 48), mutation (n = 8), or amplification (n = 3) participated. At the prespecified data cutoff (June 30, 2016), 50 patients had discontinued treatment. All responsive tumors contained FGFR2 fusions. The overall response rate was 14.8% (18.8% FGFR2 fusions only), disease control rate was 75.4% (83.3% FGFR2 fusions only), and estimated median progression-free survival was 5.8 months (95% CI, 4.3 to 7.6 months). Adverse events included hyperphosphatemia (72.1% all grade), fatigue (36.1%), stomatitis (29.5%), and alopecia (26.2%). Grade 3 or 4 treatment-related adverse events occurred in 25 patients (41%) and included hyperphosphatemia (16.4%), stomatitis (6.6%), and palmar-plantar erythrodysesthesia (4.9%). Conclusion BGJ398 is a first-in-class FGFR kinase inhibitor with manageable toxicities that shows meaningful clinical activity against chemotherapy-refractory cholangiocarcinoma containing FGFR2 fusions. This promising antitumor activity supports continued development of BGJ398 in this highly selected patient population. PMID- 29182497 TI - Effect of Prophylactic Human Papillomavirus (HPV) Vaccination on Oral HPV Infections Among Young Adults in the United States. AB - Purpose The incidence of human papilloma virus (HPV)-positive oropharyngeal cancers has risen rapidly in recent decades among men in the United States. We investigated the US population-level effect of prophylactic HPV vaccination on the burden of oral HPV infection, the principal cause of HPV-positive oropharyngeal cancers. Methods We conducted a cross-sectional study of men and women 18 to 33 years of age (N = 2,627) within the National Health and Nutrition Examination Survey 2011 to 2014, a representative sample of the US population. Oral HPV infection with vaccine types 16, 18, 6, or 11 was compared by HPV vaccination status, as measured by self-reported receipt of at least one dose of the HPV vaccine. Analyses accounted for the complex sampling design and were adjusted for age, sex, and race. Statistical significance was assessed using a quasi-score test. Results Between 2011 and 2014, 18.3% of the US population 18 to 33 years of age reported receipt of at least one dose of the HPV vaccine before the age of 26 years (29.2% in women and 6.9% in men; P < .001). The prevalence of oral HPV16/18/6/11 infections was significantly reduced in vaccinated versus unvaccinated individuals (0.11% v 1.61%; Padj = .008), corresponding to an estimated 88.2% (95% CI, 5.7% to 98.5%) reduction in prevalence after model adjustment for age, sex, and race. Notably, the prevalence of oral HPV16/18/6/11 infections was significantly reduced in vaccinated versus unvaccinated men (0.0% v 2.13%; Padj = .007). Accounting for vaccine uptake, the population-level effect of HPV vaccination on the burden of oral HPV16/18/6/11 infections was 17.0% overall, 25.0% in women, and 6.9% in men. Conclusion HPV vaccination was associated with reduction in vaccine-type oral HPV prevalence among young US adults. However, because of low vaccine uptake, the population-level effect was modest overall and particularly low in men. PMID- 29182498 TI - Effect of Single-Session, Cryogen-Cooled Monopolar Radiofrequency Therapy on Sexual Function in Women with Vaginal Laxity: The VIVEVE I Trial. AB - OBJECTIVE: This subanalysis of the VIVEVE I trial aimed to evaluate the impact of cryogen-cooled monopolar radiofrequency (CMRF) therapy, for the treatment of vaginal laxity, on the domains of sexual function included in the Female Sexual Function Index (FSFI). MATERIALS AND METHODS: The VIVEVE I clinical trial was prospective, randomized, single-blind, and Sham-controlled. Nine clinical study centers in Canada, Italy, Spain, and Japan were included. This subanalysis included premenopausal women with self-reported vaginal laxity who had >=1 term vaginal delivery and a baseline FSFI total score <=26.5, indicating sexual dysfunction. Enrolled subjects were randomized (2:1) to receive CMRF therapy [Active (90 J/cm2) vs. Sham (<=1 J/cm2)] delivered to the vaginal tissue. Independent analyses were conducted for each FSFI domain to evaluate both the mean change, as well as the clinically important change for Active- versus Sham treated subjects at 6 months post-intervention. RESULTS: Subjects randomized to Active treatment (n = 73) had greater improvement than Sham subjects (n = 35) on all FSFI domains of sexual function at 6 months postintervention. The analysis of covariance change from baseline analyses showed statistically significant improvements, in favor of Active treatment, for sexual arousal (p = 0.004), lubrication (p = 0.04), and orgasm (p = 0.007). In addition, Active treatment was associated with clinically important and statistically significant improvements in sexual desire [Odds ratio (OR) = 3.01 (1.11-8.17)], arousal [OR = 2.73 (1.06 7.04)], and orgasm [OR = 2.58 (1.08-6.18)]. CONCLUSIONS: This subanalysis showed CMRF therapy is associated with statistically significant and clinically important improvements in sexual function in women with vaginal laxity. These findings provide the first randomized, placebo-controlled energy-based device evidence for functional improvements associated with a nonsurgical modality for a highly prevalent and undertreated condition. PMID- 29182499 TI - Strategy to Identify and Test Putative Light-Sensitive Non-Opsin G-Protein Coupled Receptors: A Case Study. AB - The rise of high-throughput RNA sequencing (RNA-seq) and de novo transcriptome assembly has had a transformative impact on how we identify and study genes in the phototransduction cascade of non-model organisms. But the advantage provided by the nearly automated annotation of RNA-seq transcriptomes may at the same time hinder the possibility for gene discovery and the discovery of new gene functions. For example, standard functional annotation based on domain homology to known protein families can only confirm group membership, not identify the emergence of new biochemical function. In this study, we show the importance of developing a strategy that circumvents the limitations of semiautomated annotation and apply this workflow to photosensitivity as a means to discover non opsin photoreceptors. We hypothesize that non-opsin G-protein-coupled receptor (GPCR) proteins may have chromophore-binding lysines in locations that differ from opsin. Here, we provide the first case study describing non-opsin light sensitive GPCRs based on tissue-specific RNA-seq data of the common bay scallop Argopecten irradians (Lamarck, 1819). Using a combination of sequence analysis and three-dimensional protein modeling, we identified two candidate proteins. We tested their photochemical properties and provide evidence showing that these two proteins incorporate 11-cis and/or all-trans retinal and react to light photochemically. Based on this case study, we demonstrate that there is potential for the discovery of new light-sensitive GPCRs, and we have developed a workflow that starts from RNA-seq assemblies to the discovery of new non-opsin, GPCR-based photopigments.

PMID- 29182501 TI - Radiolar Eyes of Serpulid Worms (Annelida, Serpulidae): Structures, Function, and Phototransduction. AB - Fan worms, represented by sabellid and serpulid polychaetes, have an astonishing array of unusual eyes and photoreceptors located on their eponymous feeding appendages. Here we organize the previous descriptions of these eyes in serpulids and report new anatomical, molecular, and physiological data regarding their structure, function, and evolution and the likely identity of their phototransduction machinery. We report that, as in sabellids, serpulids display a broad diversity of radiolar eye arrangements and ocellar structures. Furthermore, the visual pigment expressed in the eyes of Spirobranchus corniculatus, a species of the charismatic Christmas tree worms, absorbs light maximally at 464 nm in wavelength. This visual pigment closely matches the spectrum of downwelling irradiance in shallow coral reef habitats and lends support to the hypothesis that these radiolar photoreceptors function as a silhouette-detecting "burglar alarm" that triggers a rapid withdrawal response when the worm is threatened by potential predators. Finally, we report on the transcriptomic sequencing results for the radiolar eyes of S. corniculatus, which express invertebrate c-type opsins in their ciliary radiolar photoreceptors, closely related to the opsin found in the radiolar eyes of the sabellid Acromegalomma interruptum. We explore the potential for a shared evolutionary lineage between the radiolar photoreceptors of serpulids and sabellids and consider these unique innovations in the broader context of metazoan eye evolution. PMID- 29182502 TI - Expression of G Proteins in the Eyes and Parietovisceral Ganglion of the Bay Scallop Argopecten irradians. AB - A multitude of image-forming eyes are spread across the bodies of certain invertebrates. Recent efforts have characterized how these eyes function, but less progress has been made toward describing the neural structures associated with them. Scallops, for example, have a distributed visual system that includes dozens of eyes whose optic nerves project to the lateral lobes of the parietovisceral ganglion (PVG). To identify sensory receptors and chemical synapses associated with the scallop visual system, we studied the expression of four G protein alpha subunits (Galphai, Galphao, Galphaq, and Galphas) in the eyes and PVG of the bay scallop Argopecten irradians (Lamarck, 1819). In the eyes of A. irradians, we noted expression of Galphao by the ciliary photoreceptors of the distal retina, expression of Galphaq by the rhabdomeric photoreceptors of the proximal retina, and the expression of Galphao and Galphaq by the cells of the cornea; we did not, however, detect expression of Galphai or Galphas in the eyes. In the PVG of A. irradians, we noted widespread expression of Galphai, Galphao, and Galphaq. The expression of Galphas was limited to fine neurites in the lateral and ventral central lobes, as well as large unipolar neurons in the dorsal central lobes. Our findings suggest that light detection by the eyes of A. irradians is conferred primarily by photoreceptors that express Galphao or Galphaq, that the corneal cells of scallops may contain sensory receptors and/or receive neural input, and that G protein labeling is useful for visualizing substructures and identifying specific populations of cells within the nervous systems of invertebrates. PMID- 29182503 TI - Molecular Evolution of Spider Vision: New Opportunities, Familiar Players. AB - Spiders are among the world's most species-rich animal lineages, and their visual systems are likewise highly diverse. These modular visual systems, composed of four pairs of image-forming "camera" eyes, have taken on a huge variety of forms, exhibiting variation in eye size, eye placement, image resolution, and field of view, as well as sensitivity to color, polarization, light levels, and motion cues. However, despite this conspicuous diversity, our understanding of the genetic underpinnings of these visual systems remains shallow. Here, we review the current literature, analyze publicly available transcriptomic data, and discuss hypotheses about the origins and development of spider eyes. Our efforts highlight that there are many new things to discover from spider eyes, and yet these opportunities are set against a backdrop of deep homology with other arthropod lineages. For example, many (but not all) of the genes that appear important for early eye development in spiders are familiar players known from the developmental networks of other model systems (e.g., Drosophila). Similarly, our analyses of opsins and related phototransduction genes suggest that spider photoreceptors employ many of the same genes and molecular mechanisms known from other arthropods, with a hypothesized ancestral spider set of four visual and four nonvisual opsins. This deep homology provides a number of useful footholds into new work on spider vision and the molecular basis of its extant variety. We therefore discuss what some of these first steps might be in the hopes of convincing others to join us in studying the vision of these fascinating creatures. PMID- 29182504 TI - Molecular Characterization of Copepod Photoreception. AB - Copepod crustaceans are an abundant and ecologically significant group whose basic biology is guided by numerous visually guided behaviors. These behaviors are driven by copepod eyes, including naupliar eyes and Gicklhorn's organs, which vary widely in structure and function among species. Yet little is known about the molecular aspects of copepod vision. In this study we present a general overview of the molecular aspects of copepod vision by identifying phototransduction genes from newly generated and publicly available RNA sequencing data and assemblies from 12 taxonomically diverse copepod species. We identify a set of 10 expressed transcripts that serve as a set of target genes for future studies of copepod phototransduction. Our more detailed evolutionary analyses of the opsin gene responsible for forming visual pigments found that all of the copepod species investigated express two main groups of opsins: middle wavelength-sensitive (MWS) opsins and pteropsins. Additionally, there is evidence from a few species (e.g., Calanus finmarchicus, Eurytemora affinis, Paracyclopina nana, and Lernaea cyprinacea) for the expression of two additional groups of opsins-the peropsins and rhodopsin 7 (Rh7) opsins-at low levels or distinct developmental stages. An ontogenetic analysis of opsin expression in Calanus finmarchicus found the expression of a single dominant MWS opsin, as well as evidence for differences in expression across development in some MWS, pteropsin, and Rh7 opsins, with expression peaking in early naupliar through early copepodite stages. PMID- 29182505 TI - Opsin Expression in the Central Nervous System of the Mantis Shrimp Neogonodactylus oerstedii. AB - Visual pigments, each composed of an opsin protein covalently bound to a chromophore molecule, confer light sensitivity for vision. The eyes of some species of stomatopod crustaceans, or mantis shrimp, can express dozens of different opsin genes. The opsin diversity, along with spectral filters and unique tripartite eye structure, bestow upon stomatopods unusually complex visual systems. Although opsins are found in tissues outside typical image-forming eyes in other animals, extraocular opsin expression in stomatopods, animals well known for their diversity of opsins, was unknown. Caudal photoreception in the central nervous system of decapod crustaceans, a group closely related to stomatopod crustaceans, is thought to be opsin based. However, electrophysiological data suggest that stomatopods do not have caudal photoreceptors. In this study, we identified mRNAs that could encode four different opsins and several components of a potential Gq-mediated phototransduction pathway in the central nervous system of the Caribbean mantis shrimp Neogonodactylus oerstedii. The four opsins are abundantly expressed in the cerebral ganglion, or brain, with little or no expression in the remainder of the ventral nerve cord. Our data suggest that there are previously undiscovered cerebral photoreceptors in stomatopods. PMID- 29182506 TI - Opsins and Their Expression Patterns in the Xiphosuran Limulus polyphemus. AB - The American horseshoe crab Limulus polyphemus (Linnaeus, 1758) is one of four extant species of xiphosuran chelicerates, the sister group to arachnids. Because of their position in the arthropod family tree and because they exhibit many plesiomorphic characteristics, Xiphosura are considered a proxy for the euchelicerate ancestor and therefore important for understanding the evolution and diversification of chelicerates and arthropods. Limulus polyphemus is the most extensively studied xiphosuran, and its visual system has long been a focus of studies critical for our understanding of basic mechanisms of vision and the evolution of visual systems in arthropods. Building upon a wealth of information about the anatomy and physiology of its visual system, advances in genetic approaches have greatly expanded possibilities for understanding its biochemistry. This review focuses on studies of opsin expression in L. polyphemus, which have been significantly advanced by the availability of transcriptomes and a recent high-quality assembly of its genome. These studies show that the repertoire of expressed opsins in L. polyphemus is far larger than anticipated, that the regulation of their expression in rhabdoms is far more complex than anticipated, and that photosensitivity may be distributed widely throughout the L. polyphemus central nervous system. The visual system of L. polyphemus is now arguably the best understood among chelicerates, and as such, it is a critical resource for furthering our understanding of the evolution and diversification of visual systems in arthropods.

AB - Despite the inverse association between skin colour and efficiency of cutaneous vitamin D synthesis, in addition to the widely accepted racial disparity in vitamin D status, populations of ethnic minority are understudied in terms of setting target serum 25-hydroxyvitamin D concentrations and corresponding dietary requirements for vitamin D. In minority groups, prevention of vitamin D deficiency on a population basis is challenging due to the lack of clarity surrounding the metabolism and transport of vitamin D. Authoritative agencies have been unable to define pregnancy-specific dietary recommendations for vitamin D, owing to an absence of sufficient evidence to confirm whether nutritional requirements for vitamin D are altered during pregnancy. While the question of setting race- and pregnancy-specific dietary reference values for vitamin D has not been addressed to date, endemic vitamin D deficiency has been reported among gravidae worldwide, specifically among ethnic minorities and white women resident at high latitude. In light of the increased risk of nutritional rickets among infants of ethnic minority, coupled with growing evidence for potential non skeletal roles of vitamin D in perinatal health, determination of the dietary vitamin D requirement that will prevent deficiency during pregnancy is a research priority. However, systematic approaches to establishing dietary requirements are limited by the quality of the available evidence and the under-representation of minority groups in clinical research. This review considers the evidence for racial differences in vitamin D status and response to vitamin D supplementation, with particular application to pregnancy-specific requirements among ethnic minorities resident at high latitudes. PMID- 29182509 TI - The 3C protease of enterovirus A71 counteracts the activity of host zinc-finger antiviral protein (ZAP). AB - Enterovirus A71 (EV-A71) is a positive-strand RNA virus that causes hand-foot mouth disease and neurological complications in children and infants. Although the underlying mechanisms remain to be further defined, impaired immunity is thought to play an important role. The host zinc-finger antiviral protein (ZAP), an IFN-stimulated gene product, has been reported to specifically inhibit the replication of certain viruses. However, whether ZAP restricts the infection of enteroviruses remains unknown. Here, we report that EV-A71 infection upregulates ZAP mRNA in RD and HeLa cells. Moreover, ZAP overexpression rendered 293 T cells resistant to EV-A71 infection, whereas siRNA-mediated depletion of endogenous ZAP enhanced EV-A71 infection. The EV-A71 infection stimulated site-specific proteolysis of two ZAP isoforms, leading to the accumulation of a 40 kDa N terminal ZAP fragment in virus-infected cells. We further revealed that the 3C protease (3Cpro) of EV-A71 mediates ZAP cleavage, which requires protease activity. Furthermore, ZAP variants with single amino acid substitutions at Gln 369 were resistant to 3Cpro cleavage, implying that Gln-369 is the sole cleavage site in ZAP. Moreover, although ZAP overexpression inhibited EV-A71 replication, the cleaved fragments did not show this effect. Our results indicate that an equilibrium between ZAP and enterovirus 3Cpro controls viral infection. The findings in this study suggest that viral 3Cpro mediated ZAP cleavage may represent a mechanism to escape host antiviral responses. PMID- 29182510 TI - High dengue virus load differentially modulates human microvascular endothelial barrier function during early infection. AB - Plasma leakage is the main pathophysiological feature in severe dengue, resulting from altered vascular barrier function associated with an inappropriate immune response triggered upon infection. The present study investigated functional changes using an electric cell-substrate impedance sensing system in four (brain, dermal, pulmonary and retinal) human microvascular endothelial cell (MEC) lines infected with purified dengue virus, followed by assessment of cytokine profiles and the expression of inter-endothelial junctional proteins. Modelling of changes in electrical impedance suggests that vascular leakage in dengue-infected MECs is mostly due to the modulation of cell-to-cell interactions, while this loss of vascular barrier function observed in the infected MECs varied between cell lines and DENV serotypes. High levels of inflammatory cytokines (IL-6 and TNF-alpha), chemokines (CXCL1, CXCL5, CXCL11, CX3CL1, CCL2 and CCL20) and adhesion molecules (VCAM-1) were differentially produced in the four infected MECs. Further, the tight junctional protein, ZO-1, was down-regulated in both the DENV-1-infected brain and pulmonary MECs, while claudin-1, PECAM-1 and VE-cadherin were differentially expressed in these two MECs after infection. Non-purified virus stock was also studied to investigate the impact of virus stock purity on dengue specific immune responses, and the results suggest that virus stock propagated through cell culture may include factors that mask or alter the DENV-specific immune responses of the MECs. The findings of the present study show that high DENV load differentially modulates human microvascular endothelial barrier function and disrupts the function of inter-endothelial junctional proteins during early infection with organ-specific cytokine production. PMID- 29182511 TI - Molecular cloning and overexpression of DGA1, an acyl-CoA-dependent diacylglycerol acyltransferase, in the oleaginous yeast Rhodosporidiobolus fluvialis DMKU-RK253. AB - Triacylglycerol (TAG) is a major component of lipid storage in yeast. The acyl CoA: diacylgycerol acyltransferase (DGAT) that catalyzes the final and rate limiting step in the production of TAG is rather interesting. Consequently, cloning and analysis of the gene-encoding TAG synthase, diacylglycerol acyltransferase gene (DGA1), of the oleaginous yeast Rhodosporidiobolus fluvialis DMKU-RK253 were undertaken. Analysis of the deduced amino acid sequence of DGA1 from R. fluvialis DMKU-RK253 (RfDGA1) showed similarity with the acyl CoA:diacylglycerol acyltransferase 2 (DGAT2) from other organisms. The cDNA of RfDGA1 was cloned into the yeast expression vector pYES2 and heterologously overexpressed in Saccharomyces cerevisiae. One of the transformants showed a 1.6 fold increase in lipid content compared with the wild-type strain harbouring the pYES2 empty vector. Furthermore, DGA1 overexpression in R. fluvialis DMKU-RK253 resulted in a 2.5-fold increase in lipid content when compared with the wild-type strain, and no significant differences in fatty acid composition were observed between RfDGA1-overexpressed and wild-type strains. Taken together, our results supported our hypothesis that the RfDGA1 is a genetic factor that can be used for the development of a strain with improved lipid accumulation capabilities. PMID- 29182513 TI - Both hypothyroidism and hyperthyroidism increase plasma irisin levels in rats. AB - Background A recently discovered hormone, irisin is accepted to be significantly involved in the regulation of body weight. Thyroid functions may be, directly or indirectly, associated with irisin. Aim The aim of the present study is to determine the effect of experimental thyroid dysfunction on irisin levels in rats. Methods The study registered 40 adult male Sprague-Dawley rats, which were allocated to groups as follows: 1. Control; 2. Hypothyroidism induced by injection of 10 mg/kg/day intraperitoneal propylthiouracil (PTU) for 3 weeks; 3. Hypothyroidism (PTU 2 weeks) + L-thyroxin (1.5 mg/kg/day for 1 week); 4. Hyperthyroidism induced in rats by 3-week thyroxin (0.3 mg/kg/day); 5. Hyperthyroidism + PTU. At the end of the study, blood samples were collected to quantify free triiodothyronine (FT3), free triiodothyronine (FT4) and irisin levels. Results FT3 and FT4 levels were reduced in hypothyroidism and were significantly elevated in hyperthyroidism (p < 0.001). Irisin values, on the other hand, were found to be elevated in both hypothyroidism and hyperthyroidism groups (p < 0.001). Conclusion The results of the study suggest that irisin values increase in thyroid dysfunction, hypo- and hyperthyroidism, and that when hypothyroidism is corrected by thyroxin administration and hyperthyroidism by PTU injection, plasma irisin values go back to normal. PMID- 29182512 TI - Global mapping of MtrA-binding sites links MtrA to regulation of its targets in Mycobacterium tuberculosis. AB - Mycobacterium tuberculosis employs two-component systems (TCSs) for survival within its host. The TCS MtrAB is conserved among mycobacteria. The response regulator MtrA is essential in M. tuberculosis. The genome-wide chromatin immunoprecipitation (ChIP) sequencing performed in this study suggested that MtrA binds upstream of at least 45 genes of M. tuberculosis, including those involved in cell wall remodelling, stress responses, persistence and regulation of transcription. It binds to the promoter regions and regulates the peptidoglycan hydrolases rpfA and rpfC, which are required for resuscitation from dormancy. It also regulates the expression of whiB4, a critical regulator of the oxidative stress response, and relF, one-half of the toxin-antitoxin locus relFG. We have identified a new consensus 9 bp loose motif for MtrA binding. Mutational changes in the consensus sequence greatly reduced the binding of MtrA to its newly identified targets. Importantly, we observed that overexpression of a gain-of function mutant, MtrAY102C, enhanced expression of the aforesaid genes in M. tuberculosis isolated from macrophages, whereas expression of each of these targets was lower in M. tuberculosis overexpressing a phosphorylation-defective mutant, MtrAD56N. This result suggests that phosphorylated MtrA (MtrA-P) is required for the expression of its targets in macrophages. Our data have uncovered new MtrA targets that suggest that MtrA is required for a transcriptional response that likely enables M. tuberculosis to persist within its host and emerge out of dormancy when the conditions are favourable.

PMID- 29182515 TI - Sesquiterpenes from the Saudi Red Sea: Litophyton arboreum with their cytotoxic and antimicrobial activities. AB - A new pseudoguaiane-type sesquiterpene named litopharbol (1) was isolated from the methanolic extract of the Red Sea soft coral Litophyton arboreum, along with known sesquiterpenoids alismol (2), alismorientol B (3), teuhetenone A (4), and calamusin I (5); steroid, 24-methyl-cholesta-5,24(28)-diene-3beta-ol (6), alkyl glyceryl ether, chimyl alcohol (7); sphingolipid, erythro-N-dodecanoyl docosasphinga-(4E,8E)-dienine (8); and nitrogenous bases, thymine (9) and thymidine (10). The structures were determined on the basis of nuclear magnetic resonance (NMR) spectroscopic (1D and 2D NMR data including heteronuclear single quantum coherence spectroscopy, heteronuclear multiple-bond correlation spectroscopy, and nuclear Overhauser effect spectroscopy) and mass spectrometric analyses. Compounds 1-5 were explored for antimicrobial activity and cancer cell line sensitivity tests. Compound 1 exhibited antibacterial activity against Bacillus cereus with a minimum inhibition concentration of 1.8 MUg/mL, whereas compound 3 showed significant potent cytotoxic effect against MCF-7 (breast cancer cells) with IC50 4.32 MUM. PMID- 29182516 TI - ProteinAC: a frequency domain technique for analyzing protein dynamics. AB - It is widely believed that the interactions of proteins with ligands and other proteins are determined by their dynamic characteristics as opposed to only static, time-invariant processes. We propose a novel computational technique, called ProteinAC (PAC), that can be used to analyze small scale functional protein motions as well as interactions with ligands directly in the frequency domain. PAC was inspired by a frequency domain analysis technique that is widely used in electronic circuit design, and can be applied to both coarse-grained and all-atom models. It can be considered as a generalization of previously proposed static perturbation-response methods, where the frequency of the perturbation becomes the key. We discuss the precise relationship of PAC to static perturbation-response schemes. We show that the frequency of the perturbation may be an important factor in protein dynamics. Perturbations at different frequencies may result in completely different response behavior while magnitude and direction are kept constant. Furthermore, we introduce several novel frequency dependent metrics that can be computed via PAC in order to characterize response behavior. We present results for the ferric binding protein that demonstrate the potential utility of the proposed techniques. PMID- 29182517 TI - The electronic and optical properties of the sulvanite compounds: a many-body perturbation and time-dependent density functional theory study. AB - We have studied, by means of first-principles calculations, the electronic and optical properties of the sulvanite family: Cu3MX4 (M = V, Nb, Ta and X = S, Se), which, due to its broad range of gaps and chemical stability, have emerged as promising materials for technological applications such as photovoltaics and transparent conductivity. To address the reliability of those properties we have used semi-local and hybrid functionals (PBEsol, HSE06), many-body perturbation theory (G0W0 approximation and Bethe-Salpeter equation), and time-dependent density functional theory (revised bootstrap kernel) to calculate the quasi particle dispersion relation, band gaps, the imaginary part of the macroscopic dielectric function and the absorption coefficient. The calculated valence band maximum and the conduction band minimum are located at the R and X-points, respectively. The calculated gaps using PBEsol are between 0.81 and 1.88 eV, with HSE06 into 1.73 and 2.94 eV, whereas the G0W0 values fall into the 1.91-3.19 eV range. The calculated dielectric functions and absorption coefficients show that all these compounds present continuous excitonic features when the Bethe-Salpeter equation is used. Contrarily, the revised bootstrap kernel is incapable of describing the excitonic spectra. The calculated optical spectra show that Cu3VS4 and Cu3MSe4 have good absorption in the visible, whereas Cu3NbS4 and Cu3TaS4 have it on the near ultraviolet. PMID- 29182518 TI - Temperature-dependence of the single-cell variability in the kinetics of transcription activation in Escherichia coli. AB - From in vivo single-cell, single-RNA measurements of the activation times and subsequent steady-state active transcription kinetics of a single-copy Lac-ara-1 promoter in Escherichia coli, we characterize the intake kinetics of the inducer (IPTG) from the media, following temperature shifts. For this, for temperature shifts of various degrees, we obtain the distributions of transcription activation times as well as the distributions of intervals between consecutive RNA productions following activation in individual cells. We then propose a novel methodology that makes use of deconvolution techniques to extract the mean and the variability of the distribution of intake times. We find that cells, following shifts to low temperatures, have higher intake times, although, counter intuitively, the cell-to-cell variability of these times is lower. We validate the results using a new methodology for direct estimation of mean intake times from measurements of activation times at various inducer concentrations. The results confirm that E. coli's inducer intake times from the environment are significantly higher following a shift to a sub-optimal temperature. Finally, we provide evidence that this is likely due to the emergence of additional rate limiting steps in the intake process at low temperatures, explaining the reduced cell-to-cell variability in intake times. PMID- 29182519 TI - Elastic moduli of a Brownian colloidal glass former. AB - The static, dynamic and flow-dependent shear moduli of a binary mixture of Brownian hard disks are studied by an event-driven molecular dynamics simulation. Thereby, the emergence of rigidity close to the glass transition encoded in the static shear modulus [Formula: see text] is accessed by three methods. Results from shear stress auto-correlation functions, elastic dispersion relations, and the elastic response to strain deformations upon the start-up of shear flow are compared. This enables one to sample the time-dependent shear modulus [Formula: see text] consistently over several decades in time. By that a very precise specification of the glass transition point and of [Formula: see text] is feasible. Predictions by mode coupling theory of a finite shear modulus at the glass transition, of alpha-scaling in fluid states close to the transition, and of shear induced decay in yielding glass states are tested and broadly verified.

PMID- 29182521 TI - Extraction and physicochemical characterization of chitin and chitosan isolated from house cricket. AB - Chitin ranks next to cellulose as the most important bio-polysaccharide which can primarily be extracted from crustacean shells. However, the emergence of new areas of the application of chitin and its derivatives are on the increase and there is growing demand for new chitin sources. In this study, therefore, an attempt was made to extract chitin from the house cricket (Brachytrupes portentosus) by a chemical method. The physicochemical properties of chitin and chitosan extracted from crickets were compared with commercial chitin and chitosan extracted from shrimps, in terms of proximate analysis in particular, of their ash and moisture content. Also, infrared spectroscopy, x-ray diffraction (XRD), scanning electron microscopy and elemental analysis were conducted. The chitin and chitosan yield of the house cricket ranges over 4.3%-7.1% and 2.4% 5.8% respectively. Chitin and chitosan from crickets compares favourably with those extracted from shrimps, and were found to exhibit some similarities. The result shows that cricket and shrimp chitin and chitosan have the same degree of acetylation and degree of deacetylation of 108.1% and 80.5% respectively, following Fourier transform infrared spectroscopy. The characteristic XRD strong/sharp peaks of 9.4 and 19.4 degrees for alpha-chitin are common for both cricket and shrimp chitin. The percentage ash content of chitin and chitosan extracted from B. portentosus is 1%, which is lower than that obtained from shrimp products. Therefore, cricket chitin and chitosan can be said to be of better quality and of purer form than commercially produced chitin and chitosan from shrimp. Based on the quality of the product, chitin and chitosan isolated from B. portentosus can replace commercial chitin and chitosan in terms of utilization and applications. Therefore, B. portentosus is a promising alternative source of chitin and chitosan. PMID- 29182522 TI - Varieties of charge distributions in coat proteins of ssRNA+ viruses. AB - A major part of the interactions involved in the assembly and stability of icosahedral, positive-sense single-stranded RNA (ssRNA+) viruses is electrostatic in nature, as can be inferred from the strong pH- and salt-dependence of their assembly phase diagrams. Electrostatic interactions do not act only between the capsid coat proteins (CPs), but just as often provide a significant contribution to the interactions of the CPs with the genomic RNA, mediated to a large extent by positively charged, flexible N-terminal tails of the CPs. In this work, we provide two clear and complementary definitions of an N-terminal tail of a protein, and use them to extract the tail sequences of a large number of CPs of ssRNA+ viruses. We examine the pH-dependent interplay of charge on both tails and CPs alike, and show that-in contrast to the charge on the CPs-the net positive charge on the N-tails persists even to very basic pH values. In addition, we note a limit to the length of the wild-type genomes of those viruses which utilize positively charged tails, when compared to viruses without charged tails and similar capsid size. At the same time, we observe no clear connection between the charge on the N-tails and the genome lengths of the viruses included in our study.

AB - We present a method for reduced graphene oxide (GO) patterning on the surface of GO film by a 445 nm solid-state laser with the adjustable fluence from 0.2-20 kJ cm-2. We demonstrate that the optimal argon concentration in air to obtain good quality reduced GO films is 90%. Varying the laser irradiation energy density allows controlling the resistance and I G /I D and I G /I 2D ratios of Raman peak intensities. As a result, we demonstrate the possibility of forming of conductive patterns with a sheet resistance of 189 Ohm/? and ~1 MUm film thickness by a local reduction of the GO. The fabricated structures reveal excellent bolometric response with a high speed and sensitivity to the radiation in the visible wavelength region.

AB - OBJECTIVES: Prolonged suppression of gastric acid secretion by proton pump inhibitors (PPIs) may alter the bacterial microbiota of the upper gastrointestinal tract and lead to small bowel bacterial overgrowth (SBBO). Published reports have shown conflicting results on the association between PPI therapy and risk of SBBO development. We evaluated whether long-term PPI treatment is associated with presence of SBBO as determined by breath hydrogen (H2) and methane (CH4) excretion. We also assessed the differences in H2/CH4 excretion patterns in patients taking PPI compared with those not taking the medication and searched for the potential predictors of a positive breath test result. MATERIAL AND METHODS: This was a prospective cohort study that included 67 PPI-treated patients (PPIT) and 62 not-receiving PPI (C, comparison). PPIT and C underwent a glucose H2/CH4 breath test (HMBT) to determine the presence of SBBO. RESULTS: The prevalence of SBBO was significantly higher in PPIT compared to C (44.8% versus 21%, p = 0.005, OR = 3.06, 95% CI 1.40-6.66) as determined by H2 and CH4 excretion. We found that PPIT had all H2 test parameters (baseline H2 levels, maximum peak of H2 as well as mean H2 through the whole test) significantly higher than C. Even those PPIT who did not meet the criteria of breath test positivity had statistically higher breath H2 levels compared to C. Although we did not observe significant differences in CH4 excretion between groups, 19.4% of PPIT and 12.9% of C would have had a false-negative HMBT results had CH4 not been taken into account. CONCLUSIONS: Long-term PPI use was found to be significantly associated with SBBO development as determined by breath H2 and CH4 excretion. CH4 determination reduces the number of falsely negative test results. PMID- 29182525 TI - Climatic Factors and Influenza Transmission, Spain, 2010-2015. AB - The spatio-temporal distribution of influenza is linked to variations in meteorological factors, like temperature, absolute humidity, or the amount of rainfall. The aim of this study was to analyse the association between influenza activity, and meteorological variables in Spain, across five influenza seasons: 2010-2011 through to 2014-2015 using generalized linear negative binomial mixed models that we calculated the weekly influenza proxies, defined as the weekly influenza-like illness rates, multiplied by the weekly proportion of respiratory specimens that tested positive for influenza. The results showed an association between influenza transmission and dew point and cumulative precipitation. In increase in the dew point temperature of 5 degrees produces a 7% decrease in the Weekly Influenza Proxy (RR 0.928, IC: 0.891-0.966), and while an increase of 10 mm in weekly rainfall equates to a 17% increase in the Weekly Influenza Proxy (RR 1.172, IC: 1.097-1.251). Influenza transmission in Spain is influenced by variations in meteorological variables as temperature, absolute humidity, or the amount of rainfall. PMID- 29182526 TI - Immunohistochemical Analysis of Rat Renal Tumours Caused by Ochratoxin A. AB - Experimental renal cancer caused by ochratoxin A (OTA) in rats was first defined in the US National Toxicology Program (1989) and raised questions about any aetiological role in human urinary tract tumours. A review of histopathology in several rat kidney tumours from dietary OTA in recently described London studies, augmented by clinical immunohistochemistry for the first time for this mycotoxin, establishes their renal tubular cell origin. It had been assumed that the toxin might cause the human urothelial tumours associated with Balkan endemic nephropathy, but the present study could not support this. Comparison with a similar review of a metastasising renal tumour from a female rat of the NTP study consistently shows the kidney as the primary carcinogenic site for OTA. Morphological heterogeneity of these kidney tumours as epithelioid and/or sarcomatoid is revealed. Leiomyosarcoma was also diagnosed, and rhabdomyosarcoma differentiation was observed in the exceptionally aggressive NTP female tumour. The present pilot study involving immunohistochemistry indicates need for wider review of archived tumours for experimental evidence before formulating any epidemiological basis from a rat model for OTA's relevance to idiopathic human renal cell carcinoma. Although the NTP study concluded that females are less sensitive to OTA than males, some female tumours still had heterogeneous morphology.

AB - An all-fiber curvature laser sensor by using a novel modal interference in-fiber structure is proposed and experimentally demonstrated. The in-fiber device, fabricated by fusion splicing of multimode fiber and double-clad fiber segments, is used as wavelength filter as well as the sensing element. By including a multimode fiber in an ordinary modal interference structure based on a double clad fiber, the fringe visibility of the filter transmission spectrum is significantly increased. By using the modal interferometer as a curvature sensitive wavelength filter within a ring cavity erbium-doped fiber laser, the spectral quality factor Q is considerably increased. The results demonstrate the reliability of the proposed curvature laser sensor with advantages of robustness, ease of fabrication, low cost, repeatability on the fabrication process and simple operation. PMID- 29182528 TI - Circular RNAs (circRNAs) in Health and Disease. AB - Splicing events do not always produce a linear transcript. Circular RNAs (circRNAs) are a class of RNA that are emerging as key new members of the gene regulatory milieu, which are produced by back-splicing events within genes. In circRNA formation, rather than being spliced in a linear fashion, exons can be circularised by use of the 3' acceptor splice site of an upstream exon, leading to the formation of a circular RNA species. circRNAs have been demonstrated across species and have the potential to present genetic information in new orientations distinct from their parent transcript. The importance of these RNA players in gene regulation and normal cellular homeostasis is now beginning to be recognised. They have several potential modes of action, from serving as sponges for micro RNAs and RNA binding proteins, to acting as transcriptional regulators. In accordance with an important role in the normal biology of the cell, perturbations of circRNA expression are now being reported in association with disease. Furthermore, the inherent stability of circRNAs conferred by their circular structure and exonuclease resistance, and their expression in blood and other peripheral tissues in association with endosomes and microvesicles, renders them excellent candidates as disease biomarkers. In this review, we explore the state of knowledge on this exciting class of transcripts in regulating gene expression and discuss their emerging role in health and disease. PMID- 29182529 TI - Placing Salt/Soy Sauce at Dining Tables and Out-Of-Home Behavior Are Related to Urinary Sodium Excretion in Japanese Secondary School Students. AB - We investigated whether home environment, salt knowledge, and salt-use behavior were associated with urinary sodium (Na) excretion in Japanese secondary school students. Students (267; mean age, 14.2 years) from Suo-Oshima, Japan, collected three overnight urine samples and completed a salt environment/knowledge/behavior questionnaire. A subset of students (n = 66) collected, on non-consecutive days, two 24 h urine samples, and this subset was used to derive a formula for estimating 24 h Na excretion. Generalized linear models were used to examine the association between salt environment/knowledge/behavior and Na excretions. Students that had salt or soy sauce placed on the dining table during meals excreted more Na than those that did not (pfor trend < 0.05). A number of foods to which the students added seasonings were positively associated with Na excretion (pfor trend = 0.005). The students who frequently bought foods at convenience stores or visited restaurants excreted more Na in urine than those who seldom bought foods (pfor trend < 0.05). Knowledge about salt or discretionary seasoning use was not significantly associated with Na excretion. The associations found in this study indicate that home environment and salt-use behavior may be a target for a public health intervention to reduce salt intake of secondary school students. PMID- 29182530 TI - Nodule-Enriched GRETCHEN HAGEN 3 Enzymes Have Distinct Substrate Specificities and Are Important for Proper Soybean Nodule Development. AB - Legume root nodules develop as a result of a symbiotic relationship between the plant and nitrogen-fixing rhizobia bacteria in soil. Auxin activity is detected in different cell types at different stages of nodule development; as well as an enhanced sensitivity to auxin inhibits, which could affect nodule development. While some transport and signaling mechanisms that achieve precise spatiotemporal auxin output are known, the role of auxin metabolism during nodule development is unclear. Using a soybean root lateral organ transcriptome data set, we identified distinct nodule enrichment of three genes encoding auxin-deactivating GRETCHEN HAGEN 3 (GH3) indole-3-acetic acid (IAA) amido transferase enzymes: GmGH3-11/12, GmGH3-14 and GmGH3-15. In vitro enzymatic assays showed that each of these GH3 proteins preferred IAA and aspartate as acyl and amino acid substrates, respectively. GmGH3-15 showed a broad substrate preference, especially with different forms of auxin. Promoter:GUS expression analysis indicated that GmGH3 14 acts primarily in the root epidermis and the nodule primordium where as GmGH3 15 might act in the vasculature. Silencing the expression of these GH3 genes in soybean composite plants led to altered nodule numbers, maturity, and size. Our results indicate that these GH3s are needed for proper nodule maturation in soybean, but the precise mechanism by which they regulate nodule development remains to be explained. PMID- 29182531 TI - Different Facets of Body Image Disturbance in Binge Eating Disorder: A Review. AB - The goal of the present review is to give an overview of the current findings on various facets of body image disturbance in Binge Eating Disorder such as body dissatisfaction, overconcern with weight and shape, body-related checking and avoidance behavior, misperception of body size, and body-related cognitive bias. In addition, treatments for a disturbed body image in BED and evidence of body image disturbance in youth with binge eating are reviewed. The results show that a disturbed body image in BED is present in the form of overconcern with weight and shape. Furthermore, there are hints that body dissatisfaction, as well as body-related checking and avoidance behavior, are also impaired. Research concerning misperception of body size in BED has been neglected so far, but first findings show that individuals with BED rate their own body shape rather accurately. Furthermore, there are first hints that body-related cognitive biases are present in individuals with BED. Moreover, in children and adolescents, there are first hints that body dissatisfaction, as well as shape and weight concerns, seem to be associated with loss of control and binge eating. Treatments aimed directly at the convertibility of a disturbed body image in BED have revealed encouraging outcomes. In conclusion, body image disturbance seems to occur in BED, and first studies show that it can be treated effectively. PMID- 29182532 TI - Human Skin Permeation Studies with PPARgamma Agonist to Improve Its Permeability and Efficacy in Inflammatory Processes. AB - Rosacea is the most common inflammatory skin disease. It is characterized by erythema, inflammatory papules and pustules, visible blood vessels, and telangiectasia. The current treatment has limitations and unsatisfactory results. Pioglitazone (PGZ) is an agonist of peroxisome proliferator-activated receptors (PPARs), a nuclear receptor that regulates important cellular functions, including inflammatory responses. The purpose of this study was to evaluate the permeation of PGZ with a selection of penetration enhancers and to analyze its effectiveness for treating rosacea. The high-performance liquid chromatography (HPLC) method was validated for the quantitative determination of PGZ. Ex vivo permeation experiments were realized in Franz diffusion cells using human skin, in which PGZ with different penetration enhancers were assayed. The results showed that the limonene was the most effective penetration enhancer that promotes the permeation of PGZ through the skin. The cytotoxicity studies and the Draize test detected cell viability and the absence of skin irritation, respectively. The determination of the skin color using a skin colorimetric probe and the results of histopathological studies confirmed the ability of PGZ limonene to reduce erythema and vasodilation. This study suggests new pharmacological indications of PGZ and its possible application in the treatment of skin diseases, namely rosacea. PMID- 29182534 TI - On-Tree Mango Fruit Size Estimation Using RGB-D Images. AB - In-field mango fruit sizing is useful for estimation of fruit maturation and size distribution, informing the decision to harvest, harvest resourcing (e.g., tray insert sizes), and marketing. In-field machine vision imaging has been used for fruit count, but assessment of fruit size from images also requires estimation of camera-to-fruit distance. Low cost examples of three technologies for assessment of camera to fruit distance were assessed: a RGB-D (depth) camera, a stereo vision camera and a Time of Flight (ToF) laser rangefinder. The RGB-D camera was recommended on cost and performance, although it functioned poorly in direct sunlight. The RGB-D camera was calibrated, and depth information matched to the RGB image. To detect fruit, a cascade detection with histogram of oriented gradients (HOG) feature was used, then Otsu's method, followed by color thresholding was applied in the CIE L*a*b* color space to remove background objects (leaves, branches etc.). A one-dimensional (1D) filter was developed to remove the fruit pedicles, and an ellipse fitting method employed to identify well-separated fruit. Finally, fruit lineal dimensions were calculated using the RGB-D depth information, fruit image size and the thin lens formula. A Root Mean Square Error (RMSE) = 4.9 and 4.3 mm was achieved for estimated fruit length and width, respectively, relative to manual measurement, for which repeated human measures were characterized by a standard deviation of 1.2 mm. In conclusion, the RGB-D method for rapid in-field mango fruit size estimation is practical in terms of cost and ease of use, but cannot be used in direct intense sunshine. We believe this work represents the first practical implementation of machine vision fruit sizing in field, with practicality gauged in terms of cost and simplicity of operation. PMID- 29182533 TI - Early Gabapentin Treatment during the Latency Period Increases Convulsive Threshold, Reduces Microglial Activation and Macrophage Infiltration in the Lithium-Pilocarpine Model of Epilepsy. AB - The lithium-pilocarpine model of epilepsy reproduces several features of temporal lobe epilepsy in humans, including the chronological timeline of an initial latency period followed by the development of spontaneous seizures. Epilepsy therapies in humans are implemented, as a rule, after the onset of the spontaneous seizures. We here studied the potential effect on epileptogenesis of starting an early treatment during the latency period, in order to prevent the development of spontaneous seizures. Adult male Wistar rats were treated with 3 mEq/kg LiCl, and 20 h later 30 mg/kg pilocarpine. Once status epilepticus (SE) was achieved, it was allowed to last for 20 min, and then motor seizures were controlled with the administration of 20 mg/kg diazepam. At 1DPSE (DPSE, days post-status epilepticus), animals started to receive 400 mg/kg/day gabapentin or saline for 4 days. At 5DPSE, we observed that SE induced an early profuse microglial and astroglial reactivity, increased synaptogenic trombospondin-1 expression and reduced AQP4 expression in astroglial ending feet. Blood brain barrier (BBB) integrity seemed to be compromised, as infiltrating NG2+ macrophages and facilitated access to the CNS was observed by transplanting eGFP+ blood cells and bone marrow-derived progenitors in the SE animals. The early 4 day gabapentin treatment successfully reduced microglial cell reactivity and blood-borne cell infiltration, without significantly altering the mRNA of proinflammatory cytokines IL-1beta and TNFalpha immediately after the treatment. After 21DSPE, another group of animals that developed SE and received 4 days of gabapentin treatment, were re-exposed to subconvulsive accumulative doses of pilocarpine (10 mg/kg/30 min) and were followed by recording the Racine scale reached. Early 4-day gabapentin treatment reduced the Racine scale reached by the animals, reduced animal mortality, and reduced the number of animals that achieved SE (34% vs. 72%). We conclude that early gabapentin treatment following SE, during the latency period, is able to reduce neuroinflammation and produces a persistent effect that limits seizures and increases convulsive threshold, probably by restricting microglial reactivity and spurious synaptogenesis. PMID- 29182535 TI - Contextual Exploration of a New Family Caregiver Support Concept for Geriatric Settings Using a Participatory Health Research Strategy. AB - Family caregivers are the backbone of the long-term care support system within the home environment. Comprehensive caregiver support programs require collaboration and coordination within the system. A new public health concept, Vade Mecum, aims to harmonize and professionalize family caregiver support initiatives in geriatric care settings in the Euregion Maas-Rhine. Exploration of the new concept recently started in Germany to gain in-depth insight into current support and the needs of the geriatric care team and family caregivers. Within the context of an exploratory qualitative study, a participatory health research (PHR) strategy was applied to make optimal use of experience and knowledge from the system. Care professionals, engaged as co-researchers, were responsible for decisions about the research question, data collection methods and procedures of engaging family caregivers. A research team representing all professions within the geriatric department was formed. Research objectives were formulated and an appropriate mix of qualitative data collection methods consisting of interviews, focus groups and story-telling was chosen. Needs and expectations of the new concept, and practical solutions for involving family caregivers were discussed. A PHR strategy resulted in initiating a qualitative study in a geriatric care setting carried out by care professionals from the department. Knowledge was generated in a co-creative manner, and co-researchers were empowered. A comprehensive understanding of the system serves as a starting point for advancement of the new family caregiver concept. PMID- 29182536 TI - Are We Underestimating Benthic Cyanotoxins? Extensive Sampling Results from Spain. AB - Microcystins (MCs) are potent hepatotoxins, and their presence in water bodies poses a threat to wildlife and human populations. Most of the available information refers to plankton, and much less is known about microcystins in other habitats. To broaden our understanding of the presence and environmental distribution of this group of toxins, we conducted extensive sampling throughout Spain, under a range of conditions and in distinct aquatic and terrestrial habitats. More than half of the tested strains were toxic; concentrations of the hepatotoxin were low compared with planktic communities, and the number of toxic variants identified in each sample of the Spanish strains ranged from 1-3. The presence of microcystins LF and LY (MC-LF and MC-LY) in the tested samples was significant, and ranged from 21.4% to 100% of the total microcystins per strain. These strains were only detected in cyanobacteria Oscillatoriales and Nostocales. We can report, for the first time, seven new species of microcystin producers in high mountain rivers and chasmoendolithic communities. This is the first report of these species in Geitlerinema and the confirmation of Anatoxin-a in Phormidium uncinatum. Our findings show that microcystins are widespread in all habitat types, including both aerophytic and endolithic peat bogs and that it is necessary to identify all the variants of microcystins in aquatic bodies as the commonest toxins sometimes represent a very low proportion of the total. PMID- 29182538 TI - Tactile Perception of Roughness and Hardness to Discriminate Materials by Friction-Induced Vibration. AB - The human fingertip is an exquisitely powerful bio-tactile sensor in perceiving different materials based on various highly-sensitive mechanoreceptors distributed all over the skin. The tactile perception of surface roughness and material hardness can be estimated by skin vibrations generated during a fingertip stroking of a surface instead of being maintained in a static position. Moreover, reciprocating sliding with increasing velocities and pressures are two common behaviors in humans to discriminate different materials, but the question remains as to what the correlation of the sliding velocity and normal load on the tactile perceptions of surface roughness and hardness is for material discrimination. In order to investigate this correlation, a finger-inspired crossed-I beam structure tactile tester has been designed to mimic the anthropic tactile discrimination behaviors. A novel method of characterizing the fast Fourier transform integral (FFT) slope of the vibration acceleration signal generated from fingertip rubbing on surfaces at increasing sliding velocity and normal load, respectively, are defined as kv and kw, and is proposed to discriminate the surface roughness and hardness of different materials. Over eight types of materials were tested, and they proved the capability and advantages of this high tactile-discriminating method. Our study may find applications in investigating humanoid robot perceptual abilities. PMID- 29182537 TI - Dynamics of Pathological and Virological Findings During Experimental Calpox Virus Infection of Common Marmosets (Callithrix jacchus). AB - Experimental intranasal infection of marmosets (Callithrix jacchus) with calpox virus results in fatal disease. Route and dose used for viral inoculation of the test animals mimics the natural transmission of smallpox, thus representing a suitable model to study pathogenesis and to evaluate new vaccines against orthopoxvirus infection. However, the pathogenic mechanisms leading to death are still unclear. Therefore, our study aimed at investigating the kinetics of pathological alterations to clarify the pathogenesis in calpox virus infection. Following intranasal inoculation with two different viral doses, common marmosets were sacrificed on days 3, 5, 7, 10 and 12 post inoculation. Collected tissue was screened using histopathology, immunohistochemistry, transmission electron microscopy, and virological assays. Our data suggest that primary replication took place in nasal and bronchial epithelia followed by secondary replication in submandibular lymph nodes and spleen. Parallel to viremia at day 7, virus was detectable in many organs, mainly located in epithelial cells and macrophages, as well as in endothelial cells. Based on the onset of clinical signs, the histological and ultrastructural lesions and the immunohistochemical distribution pattern of the virus, the incubation period was defined to last 11 days, which resembles human smallpox. In conclusion, the data indicate that the calpox model is highly suitable for studying orthopoxvirus-induced disease. PMID- 29182539 TI - Effect of Composition and Thickness on the Perpendicular Magnetic Anisotropy of (Co/Pd) Multilayers. AB - Magnetic materials with perpendicular magnetic anisotropy (PMA) have wide-ranging applications in magnetic recording and sensing devices. Multilayers comprised of ferromagnetic and non-magnetic metals (FM-NM) are interesting materials, as their magnetic anisotropy depends strongly on composition and growth parameters. In this context, (Co/Pd) multilayers have gained huge interest recently due to their robustness and tunable PMA. Here, we report a systematic study of the effect of composition on the magnetic anisotropy of (Co/Pd) multilayers grown by Direct Current (DC) magnetron sputtering. Four different series of (Co/Pd)*10 multilayers with different thicknesses of Co and Pd were examined. Vibrating sample magnetometery was used to determine the magnetic anisotropy of these films. X-ray diffraction and transmission electron microscopy experiments were performed to understand the structural morphology of the films. Our results showed that (Co/Pd)*10 multilayers exhibit PMA when the Co to Pd ratio is less than or equal to 1 and the thickness of Co layers is not more than 5 A. Maximum effective anisotropy energy is shown by the films with a Co to Pd ratio of 1/3. PMID- 29182541 TI - Ceramic-Based 4D Components: Additive Manufacturing (AM) of Ceramic-Based Functionally Graded Materials (FGM) by Thermoplastic 3D Printing (T3DP). AB - In our study, we investigated the additive manufacturing (AM) of ceramic-based functionally graded materials (FGM) by the direct AM technology thermoplastic 3D printing (T3DP). Zirconia components with varying microstructures were additively manufactured by using thermoplastic suspensions with different contents of pore forming agents (PFA), which were co-sintered defect-free. Different materials were investigated concerning their suitability as PFA for the T3DP process. Diverse zirconia-based suspensions were prepared and used for the AM of single- and multi-material test components. All of the samples were sintered defect-free, and in the end, we could realize a brick wall-like component consisting of dense (<1% porosity) and porous (approx. 5% porosity) zirconia areas to combine different properties in one component. T3DP opens the door to the AM of further ceramic-based 4D components, such as multi-color, multi-material, or especially, multi-functional components. PMID- 29182540 TI - Probing Protein Glycation by Chromatography and Mass Spectrometry: Analysis of Glycation Adducts. AB - Glycation is a non-enzymatic post-translational modification of proteins, formed by the reaction of reducing sugars and alpha-dicarbonyl products of their degradation with amino and guanidino groups of proteins. Resulted early glycation products are readily involved in further transformation, yielding a heterogeneous group of advanced glycation end products (AGEs). Their formation is associated with ageing, metabolic diseases, and thermal processing of foods. Therefore, individual glycation adducts are often considered as the markers of related pathologies and food quality. In this context, their quantification in biological and food matrices is required for diagnostics and establishment of food preparation technologies. For this, exhaustive protein hydrolysis with subsequent amino acid analysis is the strategy of choice. Thereby, multi-step enzymatic digestion procedures ensure good recoveries for the most of AGEs, whereas tandem mass spectrometry (MS/MS) in the multiple reaction monitoring (MRM) mode with stable isotope dilution or standard addition represents "a gold standard" for their quantification. Although the spectrum of quantitatively assessed AGE structures is continuously increases, application of untargeted profiling techniques for identification of new products is desired, especially for in vivo characterization of anti-glycative systems. Thereby, due to a high glycative potential of plant metabolites, more attention needs to be paid on plant-derived AGEs. PMID- 29182543 TI - Home Hemodialysis (HHD) Treatment as Effective yet Underutilized Treatment Modality in the United States. AB - End-stage renal disease (ESRD) is a major health burden and its incidence has been increasing yearly reaching 120,000 cases in 2014. Home hemodialysis (HHD) is a treatment modality option that has been shown to contribute to numerous clinical benefits but is largely underutilized due to many contributing factors. The purpose of this review paper is to analyze the advantages and disadvantages of HHD and the reasons for its low utilization with a special focus on its socioeconomic impact as compared to facility hemodialysis. Key factors contributing to HHD underutilization are related to the reimbursement system of the facility and nephrologists as well as the underutilization of the pre dialysis educational benefit. Based on this comprehensive review of the literature, we propose several suggestions which may contribute to the expansion of HHD treatment modality. PMID- 29182542 TI - The Potential of Zebrafish as a Model Organism for Improving the Translation of Genetic Anticancer Nanomedicines. AB - In the last few decades, the field of nanomedicine applied to cancer has revolutionized cancer treatment: several nanoformulations have already reached the market and are routinely being used in the clinical practice. In the case of genetic nanomedicines, i.e., designed to deliver gene therapies to cancer cells for therapeutic purposes, advances have been less impressive. This is because of the many barriers that limit the access of the therapeutic nucleic acids to their target site, and the lack of models that would allow for an improvement in the understanding of how nanocarriers can be tailored to overcome them. Zebrafish has important advantages as a model species for the study of anticancer therapies, and have a lot to offer regarding the rational development of efficient delivery of genetic nanomedicines, and hence increasing the chances of their successful translation. This review aims to provide an overview of the recent advances in the development of genetic anticancer nanomedicines, and of the zebrafish models that stand as promising tools to shed light on their mechanisms of action and overall potential in oncology. PMID- 29182544 TI - TRIM8: Making the Right Decision between the Oncogene and Tumour Suppressor Role. AB - The TRIM8/GERP protein is a member of the TRIM family defined by the presence of a common domain structure composed of a tripartite motif including a RING-finger, one or two B-box domains, and a coiled-coil motif. The TRIM8 gene maps on chromosome 10 within a region frequently found deleted and rearranged in tumours and transcribes a 3.0-kB mRNA. Its expression is mostly ubiquitously in murine and human tissues, and in epithelial and lymphoid cells, it can be induced by IFNgamma. The protein spans 551 aa and is highly conserved during evolution. TRIM8 plays divergent roles in many biological processes, including important functions in inflammation and cancer through regulating various signalling pathways. In regulating cell growth, TRIM8 exerts either a tumour suppressor action, playing a prominent role in regulating p53 tumour suppressor activity, or an oncogene function, through the positive regulation of the NF-kappaB pathway. The molecular mechanisms underlying this dual role in human cancer will be discussed in depth in this review, and it will highlight the challenge and importance of developing novel therapeutic strategies specifically aimed at blocking the pro-oncogenic arm of the TRIM8 signalling pathway without affecting its tumour suppressive effects. PMID- 29182545 TI - Detection of Abrin Holotoxin Using Novel Monoclonal Antibodies. AB - Abrin, a member of the ribosome-inactivating protein family, is produced by the Abrus precatorius plant. Having the potential to pose a severe threat to both human and animal health, abrin is classified as a Select Agent by the U.S. Department of Health and Human Services. However, an immunoassay that is specific for intact abrin holotoxin has not yet been reported. In this study, seven new monoclonal antibodies (mAbs), designated as Abrin-1 through Abrin-7 have been developed. Isotyping analyses indicate these mAbs have IgG1, IgG2a, or IgG2b heavy-chains and kappa light-chains. Western blot analyses identified two abrin A chain specific mAbs, Abrin-1 and Abrin-2, and four B-chain specific mAbs (Abrin 3, -5, -6, and -7). A sandwich enzyme-linked immunosorbent assay (ELISA), capable of detecting a mixture of abrin isoforms and agglutinins was developed using B chain specific Abrin-3 for capture and A-chain specific Abrin-2 as detector. The ELISA is highly sensitive and detects 1 ng/mL of the abrin holotoxin in phosphate buffered saline, nonfat milk, and whole milk, significantly below concentrations that would pose a health concern for consumers. This ELISA also detects native abrin in plant extracts with a very low background signal. The new abrin mAbs and ELISA should be useful for detecting this potent toxin in the milk supply chain and other complex matrices.

PMID- 29182547 TI - Gene Silencing of Argonaute5 Negatively Affects the Establishment of the Legume Rhizobia Symbiosis. AB - The establishment of the symbiosis between legumes and nitrogen-fixing rhizobia is finely regulated at the transcriptional, posttranscriptional and posttranslational levels. Argonaute5 (AGO5), a protein involved in RNA silencing, can bind both viral RNAs and microRNAs to control plant-microbe interactions and plant physiology. For instance, AGO5 regulates the systemic resistance of Arabidopsis against Potato Virus X as well as the pigmentation of soybean (Glycine max) seeds. Here, we show that AGO5 is also playing a central role in legume nodulation based on its preferential expression in common bean (Phaseolus vulgaris) and soybean roots and nodules. We also report that the expression of AGO5 is induced after 1 h of inoculation with rhizobia. Down-regulation of AGO5 gene in P. vulgaris and G. max causes diminished root hair curling, reduces nodule formation and interferes with the induction of three critical symbiotic genes: Nuclear Factor Y-B (NF-YB), Nodule Inception (NIN) and Flotillin2 (FLOT2). Our findings provide evidence that the common bean and soybean AGO5 genes play an essential role in the establishment of the symbiosis with rhizobia. PMID- 29182549 TI - Effects of Group Counseling Programs, Cognitive Behavioral Therapy, and Sports Intervention on Internet Addiction in East Asia: A Systematic Review and Meta Analysis. AB - To evaluate the effects of group counseling programs, cognitive behavioral therapy (CBT), and sports intervention on Internet addiction (IA), a systematic search in ten databases was performed to identify eligible studies without language restrictions up to January 2017. A meta-analysis and trial sequential analysis (TSA) was performed, respectively. A total of 58 randomized controlled trials (RCTs), which included 2871 participants, were incorporated into our meta analysis. The results showed that group counseling programs, CBT, and sports intervention could significantly reduce IA levels (group counseling program: standardized mean difference (SMD), -1.37; 95% confidence interval (CI), -1.89 to -0.85; CBT: SMD, -1.88; 95% CI, -2.53 to -1.23; sports intervention: SMD, -1.70; 95% CI, -2.14 to -1.26). For group counseling programs, this treatment was more effective in four dimensions of IA, including time management, interpersonal and health issues, tolerance, and compulsive Internet use. For CBT, this treatment yielded a positive change in depression, anxiousness, aggressiveness, somatization, social insecurity, phobic anxiety, paranoid ideation, and psychoticism. For sports intervention, the significant effects were also observed in all dimensions of the IA scale. Each of group counseling programs, cognitive behavioral therapy, and sports intervention had a significant effect on IA and psychopathological symptoms. Sports intervention could improve withdrawal symptoms especially. PMID- 29182548 TI - Identification of DNA-protein Binding Sites through Multi-Scale Local Average Blocks on Sequence Information. AB - DNA-protein interactions appear as pivotal roles in diverse biological procedures and are paramount for cell metabolism, while identifying them with computational means is a kind of prudent scenario in depleting in vitro and in vivo experimental charging. A variety of state-of-the-art investigations have been elucidated to improve the accuracy of the DNA-protein binding sites prediction. Nevertheless, structure-based approaches are limited under the condition without 3D information, and the predictive validity is still refinable. In this essay, we address a kind of competitive method called Multi-scale Local Average Blocks (MLAB) algorithm to solve this issue. Different from structure-based routes, MLAB exploits a strategy that not only extracts local evolutionary information from primary sequences, but also using predicts solvent accessibility. Moreover, the construction about predictors of DNA-protein binding sites wields an ensemble weighted sparse representation model with random under-sampling. To evaluate the performance of MLAB, we conduct comprehensive experiments of DNA-protein binding sites prediction. MLAB gives M C C of 0.392 , 0.315 , 0.439 and 0.245 on PDNA 543, PDNA-41, PDNA-316 and PDNA-52 datasets, respectively. It shows that MLAB gains advantages by comparing with other outstanding methods. M C C for our method is increased by at least 0.053 , 0.015 and 0.064 on PDNA-543, PDNA-41 and PDNA-316 datasets, respectively.

AB - The availability of the genome sequence of the unisexual (male-female) Caenorhabditis nigoni offers an opportunity to compare its non-coding features with the related hermaphroditic species Caenorhabditis briggsae; to understand the evolutionary dynamics of their tandem repeat sequences (satellites), as a result of evolution from the unisexual ancestor. We take advantage of the previously developed SATFIND program to build satellite families defined by a consensus sequence. The relative number of satellites (satellites/Mb) in C. nigoni is 24.6% larger than in C. briggsae. Some satellites in C. nigoni have developed from a proto-repeat present in the ancestor species and are conserved as an isolated sequence in C. briggsae. We also identify unique satellites which occur only once and joint satellite families with a related sequence in both species. Some of these families are only found in C. nigoni, which indicates a recent appearance; they contain conserved adjacent 5' and 3' regions, which may favor transposition. Our results show that the number, length and turnover of satellites are restricted in the hermaphrodite C. briggsae when compared with the unisexual C. nigoni. We hypothesize that this results from differences in unequal recombination during meiotic chromosome pairing, which limits satellite turnover in hermaphrodites.

AB - Ultrathin, transparent and flexible capacitors using graphene as the bottom electrodes were directly fabricated on polyethylene naphthalate (PEN) substrates. ZrO2 dielectric films were deposited on the treated surface of graphene by atomic layer deposition (ALD). The deposition process did not introduce any detectible defects in the graphene, as indicated by Raman measurements, guaranteeing the electrical performances of the graphene electrodes. The Aluminum-doped zinc oxide (AZO) films were prepared as the top electrodes using the ALD technique. The capacitors presented a high capacitance density (10.3 fF/MUm2 at 10 kHz) and a relatively low leakage current (5.3 * 10-6 A/cm2 at 1 V). Bending tests revealed that the capacitors were able to work normally at an outward bending radius of 10 mm without any deterioration of electrical properties. The capacitors exhibited an average optical transmittance of close to 70% at visible wavelengths. Thus, it opens the door to practical applications in transparent integrated circuits. PMID- 29182552 TI - Study on the Anticoagulant or Procoagulant Activities of Type II Phenolic Acid Derivatives. AB - In this study, three type II phenolic acids (caffeic acid, p-hydroxycinnamic acid, and ferulic acid) were used to synthesize a total of 18 phenolic acid derivatives. With molecular docking for molecule design and target protein (factors) screening, in combination with the confirmation of target proteins (factors) by surface plasmon resonance, and the evaluation of haemostatic and anticoagulant activities with five blood assays (plasma recalcification time, prothrombin time, activated partial thromboplastin time, fibrinogen, and thrombin time), the data indicated that caffeic acid derivatives showed certain anticoagulant or procoagulant activities and that two other series contained compounds with the best anticoagulant activities. Using Materials Studio analysis, particular functional groups that affect anticoagulant or procoagulant activities were revealed, and these conclusions can guide the discovery of compounds with better activities. PMID- 29182553 TI - Coumarin Derivatives Solvent-Free Synthesis under Microwave Irradiation over Heterogeneous Solid Catalysts. AB - A suitable methodology of synthesis of coumarin derivatives by Pechmann reaction over heterogeneous solid acid catalysts in a free solvent media under microwave irradiation is described. Resorcinol, phenol and ethyl acetoacetate were selected as model reactants in the Pechmann condensation. The catalytic activity of several materials-Amberlyst-15, zeolite beta and sulfonic acid functionalized hybrid silica-in solvent-free microwave-assisted synthesis of the corresponding coumarin derivatives has been investigated in detail. 7-Hydroxy-4-methylcoumarin and 4-methylcoumarin were obtained in 97% and 43% yields, respectively, over Amberlyst-15. This was the most active catalyst in the Pechmann reaction under studied conditions. PMID- 29182554 TI - Alcohol Interactions with Lipid Bilayers. AB - We investigate the structural changes to lipid membrane that ensue from the addition of aliphatic alcohols with various alkyl tail lengths. Small angle neutron diffraction from flat lipid bilayers that are hydrated through water vapor has been employed to eliminate possible artefacts of the membrane curvature and the alcohol's membrane-water partitioning. We have observed clear changes to membrane structure in both transversal and lateral directions. Most importantly, our results suggest the alteration of the membrane-water interface. The water encroachment has shifted in the way that alcohol loaded bilayers absorbed more water molecules when compared to the neat lipid bilayers. The experimental results have been corroborated by molecular dynamics simulations to reveal further details. Namely, the order parameter profiles have been fruitful in correlating the mechanical model of structural changes to the effect of anesthesia. PMID- 29182555 TI - Characterization and Computation of Yb/TiO2 and Its Photocatalytic Degradation with Benzohydroxamic Acid. AB - Yb-doped TiO2 (Yb/TiO2) compositions were synthesized by sol-gel method, and the prepared materials were characterized by X-ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS), UV-visible diffuse-reflectance spectrum (UV-Vis DRS), transmission electron microscope (TEM) and high resolution transmission electron microscope (HRTEM), energy dispersive spectrometer (EDS), and N2 adsorption. A beneficiation reagent of benzohydroxamic acid (BHA) was used to test the photocatalytic activity of Yb/TiO2. The characterizations indicate that the doping of Yb could inhibit the crystal growth of TiO2, enhance the specific surface area, increase the binding energy of Ti2p, and also slightly expand the adsorption ranges to visible light. Furthermore, the computation of band structure also indicates that Yb-doped TiO2 could make the forbidden band narrower than pure anatase TiO2, which presents a red shift in the absorption spectrum. As a result of the photodegradation experiment on BHA, Yb/TiO2 (0.50% in mass) sintered at 450 degrees C displayed the highest catalytic activity for BHA when compared with pure TiO2 or other doped Yb/TiO2 compositions, and more than 89.2% of the total organic carbon was removed after 120 min. Almost all anions, including Cl-, HCO3-, NO3-, and SO42-, inhibited the degradation of BHA by Yb/TiO2, and their inhibition effects followed the order of HCO3- > NO3- > SO42- > Cl-. Cations of Na+, K+, Ca2+, and Mg2+ displayed a slight suppressing effect due to the impact of Cl- coexisting in the solution. In addition, Yb/TiO2 maintained a high photocatalytic ability with respect to BHA after four runs. It is hypothesized that .OH is one of the main species involved in the photodegradation of BHA, and the mutual transformation of Yb3+ and Yb2+ could promote the separation of electron-hole pairs. PMID- 29182556 TI - Long Term Depression in Rat Hippocampus and the Effect of Ethanol during Fetal Life. AB - Alcohol (ethanol) disturbs cognitive functions including learning and memory in humans, non-human primates, and laboratory animals such as rodents. As studied in animals, cellular mechanisms for learning and memory include bidirectional synaptic plasticity, long-term potentiation (LTP), and long-term depression (LTD), primarily in the hippocampus. Most of the research in the field of alcohol has analyzed the effects of ethanol on LTP; however, with recent advances in the understanding of the physiological role of LTD in learning and memory, some authors have examined the effects of ethanol exposure on this particular signal. In the present review, I will focus on hippocampal LTD recorded in rodents and the effects of fetal alcohol exposure on this signal. A synthesis of the findings indicates that prenatal ethanol exposure disturbs LTD concurrently with LTP in offspring and that both glutamatergic and gamma-aminobutyric acid (GABA) neurotransmissions are altered and contribute to LTD disturbances. Although the ultimate mode of action of ethanol on these two transmitter systems is not yet clear, novel suggestions have recently appeared in the literature. PMID- 29182557 TI - Effect of Dietary Acidolysis-Oxidized Konjac Glucomannan Supplementation on Serum Immune Parameters and Intestinal Immune-Related Gene Expression of Schizothorax prenanti. AB - The present study was conducted to investigate the effects of dietary acidolysis oxidized konjac glucomannan (A-OKGM) (0%, 0.4%, 0.8%, and 1.6%) supplementation on the immunity and expression of immune-related genes in Schizothorax prenanti. After feeding for eight weeks, the serum and guts were used for measurement of biochemical parameters, and immune-related gene expression in the gut were also analyzed by real-time quantitative polymerase chain reaction (RT-qPCR). C reactive protein and IgM levels were significantly higher in the A-OKGM fed groups than in the control group, regardless of the dosage. The 0.4% and 1.6% A OKGM groups showed significant up-regulation of tumor necrosis factor alpha (TNFalpha) in the anterior gut. The 0.8% and 1.6% A-OKGM groups also showed significantly enhanced TNFalpha expression in the mid- and distal guts. Interleukin-1beta (IL-1beta) expression in the anterior gut of fish fed with 0.4% and 1.6% A-OKGM diets was significantly enhanced. The 0.8% and 1.6% A-OKGM diets resulted in significantly increased the expression of IL-1beta in the distal gut. Similarly, the interleukin-6 (IL-6) messenger RNA (mRNA) levels in the 0.4% and 1.6% diet groups were significantly higher in the anterior gut. The 0.8% and 1.6% A-OKGM diet groups showed significant induction of IL-6 gene expression in the distal gut. A-OKGM modified from KGM can act as an immunostimulant to enhance the immunity of S. prenanti. PMID- 29182558 TI - An Isoxazole Chalcone Derivative Enhances Melanogenesis in B16 Melanoma Cells via the Akt/GSK3beta/beta-Catenin Signaling Pathways. AB - Plants or plant-derived products have been routinely used in several traditional medicine systems for vitiligo treatment. It is well-known that melanogenesis can be promoted by certain flavonoid compounds isolated from the traditional Uyghur medicinal plant, Kaliziri. Therefore, Chalcones, one class of flavonoid compounds, has become an interesting target for the development of anti-vitiligo agents. A series of novel isoxazole chalcone derivatives have been designed, synthesized, and evaluated for biological activities by our group. Among them, derivative 1-(4-((3-phenylisoxazol-5-yl)methoxy)phenyl)-3-phenylprop-2-en-1-one (PMPP) was identified as a potent tyrosinase activator with better activity and lower toxicity than the positive control 8-methoxypsoralen (8-MOP) in this study. Further investigations revealed that Akt and GSK3beta were the signaling pathways involved in the hyperpigmentation of PMPP. Overall, these studies may provide a convenient and novel approach for the further development of anti-vitiligo agents. PMID- 29182559 TI - Study of Perfluorophosphonic Acid Surface Modifications on Zinc Oxide Nanoparticles. AB - In this study, perfluorinated phosphonic acid modifications were utilized to modify zinc oxide (ZnO) nanoparticles because they create a more stable surface due to the electronegativity of the perfluoro head group. Specifically, 12 pentafluorophenoxydodecylphosphonic acid, 2,3,4,5,6-pentafluorobenzylphosphonic acid, and (1H,1H,2H,2H-perfluorododecyl)phosphonic acid have been used to form thin films on the nanoparticle surfaces. The modified nanoparticles were then characterized using infrared spectroscopy, X-ray photoelectron spectroscopy, and solid-state nuclear magnetic resonance spectroscopy. Dynamic light scattering and scanning electron microscopy-energy dispersive X-ray spectroscopy were utilized to determine the particle size of the nanoparticles before and after modification, and to analyze the film coverage on the ZnO surfaces, respectively. Zeta potential measurements were obtained to determine the stability of the ZnO nanoparticles. It was shown that the surface charge increased as the alkyl chain length increases. This study shows that modifying the ZnO nanoparticles with perfluorinated groups increases the stability of the phosphonic acids adsorbed on the surfaces. Thermogravimetric analysis was used to distinguish between chemically and physically bound films on the modified nanoparticles. The higher weight loss for 12-pentafluorophenoxydodecylphosphonic acid and (1H,1H,2H,2H perfluorododecyl)phosphonic acid modifications corresponds to a higher surface concentration of the modifications, and, ideally, higher surface coverage. While previous studies have shown how phosphonic acids interact with the surfaces of ZnO, the aim of this study was to understand how the perfluorinated groups can tune the surface properties of the nanoparticles. PMID- 29182560 TI - Preparation of Al/Fe-Pillared Clays: Effect of the Starting Mineral. AB - Four natural clays were modified with mixed polyoxocations of Al/Fe for evaluating the effect of the physicochemical properties of the starting materials (chemical composition, abundance of expandable clay phases, cationic exchange capacity and textural properties) on final physicochemical and catalytic properties of Al/Fe-PILCs. The aluminosilicate denoted C2 exhibited the highest potential as starting material in the preparation of Al/Fe-PILC catalysts, mainly due to its starting cationic exchange capacity (192 meq/100 g) and the dioctahedral nature of the smectite phase. These characteristics favored the intercalation of the mixed (Al13-x/Fex)7+ Keggin-type polyoxocations, stabilizing a basal spacing of 17.4 A and high increase of the BET surface (194 m2/g), mainly represented in microporous content. According to H2-TPR analyses, catalytic performance of the incorporated Fe in the Catalytic Wet Peroxide Oxidation (CWPO) reaction strongly depends on the level of location in mixed Al/Fe pillars. Altogether, such physicochemical characteristics promoted high performance in CWPO catalytic degradation of methyl orange in aqueous medium at very mild reaction temperatures (25.0 +/- 1.0 degrees C) and pressure (76 kPa), achieving TOC removal of 52% and 70% of azo-dye decolourization in only 75 min of reaction under very low concentration of clay catalyst (0.05 g/L). PMID- 29182561 TI - Analysis of MicroRNA Expression in Newborns with Differential Birth Weight Using Newborn Screening Cards. AB - Birth weight is an early predictor for metabolic diseases and microRNAs (miRNAs) are proposed as fetal programming participants. To evaluate the use of dried blood spots (DBS) on newborn screening cards (NSC) as a source of analyzable miRNAs, we optimized a commercial protocol to recover total miRNA from normal birth weight (NBW, n = 17-20), low birth weight (LBW, n = 17-20) and high birth weight (macrosomia, n = 17-20) newborns and analyzed the relative expression of selected miRNAs by stem-loop RT-qPCR. The possible role of miRNAs on the fetal programming of metabolic diseases was explored by bioinformatic tools. The optimized extraction of RNA resulted in a 1.2-fold enrichment of miRNAs respect to the commercial kit. miR-33b and miR-375 were overexpressed in macrosomia 9.8 fold (p < 0.001) and 1.7-fold, (p < 0.05), respectively and miR-454-3p was overexpressed in both LBW and macrosomia (19.7-fold, p < 0.001 and 10.8-fold, p < 0.001, respectively), as compared to NBW. Potential target genes for these miRNAs are associated to cyclic-guanosine monophosphate (cGMP)-dependent protein kinase (PKG), mitogen-activated protein kinase (MAPK), type 2 diabetes, transforming growth factor-beta (TGF-beta)and Forkhead box O protein (FoxO) pathways. In summary, we improved a protocol for analyzing miRNAs from NSC and provide the first evidence that birth weight modifies the expression of miRNAs associated to adult metabolic dysfunctions. Our work suggests archived NSC are an invaluable resource in the search for fetal programming biomarkers. PMID- 29182562 TI - Simple Screening of Listeria monocytogenes Based on a Fluorescence Assay via a Laminated Lab-On-Paper Chip. AB - Monitoring food safety is essential for protecting the health and safety of consumers. Conventional methods used are time consuming and laborious, requiring anywhere from three to seven days to obtain results. Thus, better monitoring methods are required. In this study, a laminated lab-on-paper chip was developed, and its use for the screening of ready-to-eat seafood was demonstrated. The assay on a chip was based on loop-mediated isothermal DNA amplification (LAMP) of the hly gene of Listeria monocytogenes and fluorescence signal detection via SYBR GoldTM. Overall assay processes were completed in 4.5 h., (including 3.5 h. incubation for the bacteria enrichment, direct DNA amplification with no DNA extraction, and signal detection), without relying on standard laboratory facilities. Only positive samples induced fluorescence signals on chip upon illumination with UV light (lambda = 460). The method has a limit of detection of 100 copies of L. monocytogenes DNA per 50 g of sample. No cross-reactivity was observed in samples contaminated with other bacteria. On-site monitoring of the seafood products using this chip revealed that one of 30 products from low sanitation vendors (3.33%) were contaminated, and these agreed with the results of PCR. The results demonstrated a benefit of this chip assay for practical on site monitoring. PMID- 29182563 TI - Development of a High Precision Displacement Measurement System by Fusing a Low Cost RTK-GPS Sensor and a Force Feedback Accelerometer for Infrastructure Monitoring. AB - A displacement measurement system fusing a low cost real-time kinematic global positioning system (RTK-GPS) receiver and a force feedback accelerometer is proposed for infrastructure monitoring. The proposed system is composed of a sensor module, a base module and a computation module. The sensor module consists of a RTK-GPS rover and a force feedback accelerometer, and is installed on a target structure like conventional RTK-GPS sensors. The base module is placed on a rigid ground away from the target structure similar to conventional RTK-GPS bases, and transmits observation messages to the sensor module. Then, the initial acceleration, velocity and displacement responses measured by the sensor module are transmitted to the computation module located at a central monitoring facility. Finally, high precision and high sampling rate displacement, velocity, and acceleration are estimated by fusing the acceleration from the accelerometer, the velocity from the GPS rover, and the displacement from RTK-GPS. Note that the proposed displacement measurement system can measure 3-axis acceleration, velocity as well as displacement in real time. In terms of displacement, the proposed measurement system can estimate dynamic and pseudo-static displacement with a root-mean-square error of 2 mm and a sampling rate of up to 100 Hz. The performance of the proposed system is validated under sinusoidal, random and steady-state vibrations. Field tests were performed on the Yeongjong Grand Bridge and Yi Sun-sin Bridge in Korea, and the Xihoumen Bridge in China to compare the performance of the proposed system with a commercial RTK-GPS sensor and other data fusion techniques. PMID- 29182564 TI - Oral Mucositis in Pediatric Patients in Treatment for Acute Lymphoblastic Leukemia. AB - Oral mucositis in oncologic patients is the most undesirable event of the chemotherapeutic treatment. This study aimed to identify damage to the oral cavity resulting from chemotherapy in pediatric patients with acute lymphoblastic leukemia (ALL). This is a prospective study with a sample of 42 children and adolescents evaluated for 10 consecutive weeks after diagnosis. The modified Oral Assessment Guide (OAG) was used, and data were analyzed by Spearman's rank correlation coefficient (alpha = 5%). Changes to the normal lips and saliva were positively related to an increase in the OAG score during all 10 weeks of evaluation. Alterations to the labial mucosa were correlated with an increase in the OAG score from the 2nd to 10th week, which was also found for changes in the tongue and in the swallowing function in Weeks 1, 6, 8, 9, and 10 and for gum changes from the 5th to 7th week. No significant vocal changes were correlated with the total OAG score at any point during the monitoring period. Changes in lips, cheek and/or palatal mucosa, labial mucosa, and gum areas and in swallowing function were positively correlated with an increase in the severity of oral mucositis in patients with ALL after beginning chemotherapeutic treatment. PMID- 29182565 TI - PPARgamma Modulates Long Chain Fatty Acid Processing in the Intestinal Epithelium. AB - Nuclear receptor PPARgamma affects lipid metabolism in several tissues, but its role in intestinal lipid metabolism has not been explored. As alterations have been observed in the plasma lipid profile of ad libitum fed intestinal epithelium specific PPARgamma knockout mice (iePPARgammaKO), we submitted these mice to lipid gavage challenges. Within hours after gavage with long chain unsaturated fatty acid (FA)-rich canola oil, the iePPARgammaKO mice had higher plasma free FA levels and lower gastric inhibitory polypeptide levels than their wild-type (WT) littermates, and altered expression of incretin genes and lipid metabolism associated genes in the intestinal epithelium. Gavage with the medium chain saturated FA-rich coconut oil did not result in differences between the two genotypes. Furthermore, the iePPARgammaKO mice did not exhibit defective lipid uptake and stomach emptying; however, their intestinal transit was more rapid than in WT mice. When fed a canola oil-rich diet for 4.5 months, iePPARgammaKO mice had higher body lean mass than the WT mice. We conclude that intestinal epithelium PPARgamma is activated preferentially by long chain unsaturated FAs compared to medium chain saturated FAs. Furthermore, we hypothesize that the iePPARgammaKO phenotype originates from altered lipid metabolism and release in epithelial cells, as well as changes in intestinal motility. PMID- 29182566 TI - Insights into Insulin Fibril Assembly at Physiological and Acidic pH and Related Amyloid Intrinsic Fluorescence. AB - Human insulin is a widely used model protein for the study of amyloid formation as both associated to insulin injection amyloidosis in type II diabetes and highly prone to form amyloid fibrils in vitro. In this study, we aim to gain new structural insights into insulin fibril formation under two different aggregating conditions at neutral and acidic pH, using a combination of fluorescence, circular dichroism, Fourier-transform infrared spectroscopy, and transmission electron miscroscopy. We reveal that fibrils formed at neutral pH are morphologically different from those obtained at lower pH. Moreover, differences in FTIR spectra were also detected. In addition, only insulin fibrils formed at neutral pH showed the characteristic blue-green fluorescence generally associated to amyloid fibrils. So far, the molecular origin of this fluorescence phenomenon has not been clarified and different hypotheses have been proposed. In this respect, our data provide experimental evidence that allow identifying the molecular origin of such intrinsic property. PMID- 29182567 TI - Mathematical Model for Localised and Surface Heat Flux of the Human Body Obtained from Measurements Performed with a Calorimetry Minisensor. AB - The accuracy of the direct and local measurements of the heat power dissipated by the surface of the human body, using a calorimetry minisensor, is directly related to the calibration rigor of the sensor and the correct interpretation of the experimental results. For this, it is necessary to know the characteristics of the body's local heat dissipation. When the sensor is placed on the surface of the human body, the body reacts until a steady state is reached. We propose a mathematical model that represents the rate of heat flow at a given location on the surface of a human body by the sum of a series of exponentials: W(t) = A0 + ?Aiexp(-t/taui). In this way, transient and steady states of heat dissipation can be interpreted. This hypothesis has been tested by simulating the operation of the sensor. At the steady state, the power detected in the measurement area (4 cm2) varies depending on the sensor's thermostat temperature, as well as the physical state of the subject. For instance, for a thermostat temperature of 24 degrees C, this power can vary between 100-250 mW in a healthy adult. In the transient state, two exponentials are sufficient to represent this dissipation, with 3 and 70 s being the mean values of its time constants. PMID- 29182568 TI - A Quartz Crystal Microbalance Immunosensor for Stem Cell Selection and Extraction. AB - A cost-effective immunosensor for the detection and isolation of dental pulp stem cells (DPSCs) based on a quartz crystal microbalance (QCM) has been developed. The recognition mechanism relies on anti-CD34 antibodies, DPSC-specific monoclonal antibodies that are anchored on the surface of the quartz crystals. Due to its high specificity, real time detection, and low cost, the proposed technology has a promising potential in the field of cell biology, for the simultaneous detection and sorting of stem cells from heterogeneous cell samples. The QCM surface was properly tailored through a biotinylated self-assembled monolayer (SAM). The biotin-avidin interaction was used to immobilize the biotinylated anti-CD34 antibody on the gold-coated quartz crystal. After antibody immobilization, a cellular pellet, with a mixed cell population, was analyzed; the results indicated that the developed QCM immunosensor is highly specific, being able to detect and sort only CD34+ cells. Our study suggests that the proposed technology can detect and efficiently sort any kind of cell from samples with high complexity, being simple, selective, and providing for more convenient and time-saving operations. PMID- 29182569 TI - Knee Impedance Modulation to Control an Active Orthosis Using Insole Sensors. AB - Robotic devices for rehabilitation and gait assistance have greatly advanced with the objective of improving both the mobility and quality of life of people with motion impairments. To encourage active participation of the user, the use of admittance control strategy is one of the most appropriate approaches, which requires methods for online adjustment of impedance components. Such approach is cited by the literature as a challenge to guaranteeing a suitable dynamic performance. This work proposes a method for online knee impedance modulation, which generates variable gains through the gait cycle according to the users' anthropometric data and gait sub-phases recognized with footswitch signals. This approach was evaluated in an active knee orthosis with three variable gain patterns to obtain a suitable condition to implement a stance controller: two different gain patterns to support the knee in stance phase, and a third pattern for gait without knee support. The knee angle and torque were measured during the experimental protocol to compare both temporospatial parameters and kinematics data with other studies of gait with knee exoskeletons. The users rated scores related to their satisfaction with both the device and controller through QUEST questionnaires. Experimental results showed that the admittance controller proposed here offered knee support in 50% of the gait cycle, and the walking speed was not significantly different between the three gain patterns (p = 0.067). A positive effect of the controller on users regarding safety during gait was found with a score of 4 in a scale of 5. Therefore, the approach demonstrates good performance to adjust impedance components providing knee support in stance phase. PMID- 29182570 TI - Effect of Shot Noise on Simultaneous Sensing in Frequency Division Multiplexed Diffuse Optical Tomographic Imaging Process. AB - Diffuse optical tomography (DOT) has been studied for use in the detection of breast cancer, cerebral oxygenation, and cognitive brain signals. As optical imaging studies have increased significantly, acquiring imaging data in real time has become increasingly important. We have developed frequency-division multiplexing (FDM) DOT systems to analyze their performance with respect to acquisition time and imaging quality, in comparison with the conventional time division multiplexing (TDM) DOT. A large tomographic area of a cylindrical phantom 60 mm in diameter could be successfully reconstructed using both TDM DOT and FDM DOT systems. In our experiment with 6 source-detector (S-D) pairs, the TDM DOT and FDM DOT systems required 6.18 and 1 s, respectively, to obtain a single tomographic data set. While the absorption coefficient of the reconstruction image was underestimated in the case of the FDM DOT, we experimentally confirmed that the abnormal region can be clearly distinguished from the background phantom using both methods. PMID- 29182571 TI - Graphene Oxide-Silver Nanoparticles Nanocomposite Stimulates Differentiation in Human Neuroblastoma Cancer Cells (SH-SY5Y). AB - Recently, graphene and graphene related nanocomposite receive much attention due to high surface-to-volume ratio, and unique physiochemical and biological properties. The combination of metallic nanoparticles with graphene-based materials offers a promising method to fabricate novel graphene-silver hybrid nanomaterials with unique functions in biomedical nanotechnology, and nanomedicine. Therefore, this study was designed to prepare graphene oxide (GO) silver nanoparticles (AgNPs) nanocomposite (GO-AgNPs) containing two different nanomaterials in single platform with distinctive properties using luciferin as reducing agents. In addition, we investigated the effect of GO-AgNPs on differentiation in SH-SY5Y cells. The synthesized GO-AgNPs were characterized by ultraviolet-visible absorption spectroscopy (UV-vis), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy. The differentiation was confirmed by series of cellular and biochemical assays. The AgNPs were distributed uniformly on the surface of graphene oxide with an average size of 25 nm. As prepared GO-AgNPOs induces differentiation by increasing the expression of neuronal differentiation markers and decreasing the expression of stem cell markers. The results indicated that the redox biology involved the expression of various signaling molecules, which play an important role in differentiation. This study suggests that GO-AgNP nanocomposite could stimulate differentiation of SH-SY5Y cells. Furthermore, understanding the mechanisms of differentiation of neuroblastoma cells could provide new strategies for cancer and stem cell therapies. Therefore, these studies suggest that GO-AgNPs could target specific chemotherapy-resistant cells within a tumor. PMID- 29182572 TI - Aberrant Lipid Metabolism in Hepatocellular Carcinoma Revealed by Liver Lipidomics. AB - BACKGROUND: The aim of this study was to characterize the disorder of lipid metabolism in hepatocellular carcinoma (HCC). HCC is a worldwide disease. The research into the disorder of lipid metabolism in HCC is very limited. Study of lipid metabolism in liver cancer tissue may have the potential to provide new insight into HCC mechanisms. METHODS: A lipidomics study of HCC based on Ultra high performance liquid chromatography-electronic spray ionization-QTOF mass spectrometer (UPLC-ESI-QTOF MS) and Matrix assisted laser desorption ionization fourier transform ion cyclotron resonance mass spectrometer (MALDI-FTICR MS) was performed. RESULTS: Triacylglycerols (TAGs) with the number of double bond (DB) > 2 (except 56:5 and 56:4 TAG) were significantly down-regulated; conversely, others (except 52:2 TAG) were greatly up-regulated in HCC tissues. Moreover, the more serious the disease was, the higher the saturated TAG concentration and the lower the polyunsaturated TAG concentration were in HCC tissues. The phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylinositol (PI) were altered in a certain way. Sphingomyelin (SM) was up-regulated and ceramide (Cer) were down-regulated in HCC tissues. CONCLUSIONS: To our knowledge, this is the first such report showing a unique trend of TAG, PC, PE and PI. The use of polyunsaturated fatty acids, like eicosapentanoic and docosahexanoic acid, as supplementation, proposed for the treatment of Non-alcoholic steatohepatitis (NASH), may also be effective for the treatment of HCC.

AB - In this study, a graphene-doped porous silicon (G-doped/p-Si) substrate for low ppm H2 gas detection by an inexpensive synthesis route was proposed as a potential noble graphene-based gas sensor material, and to understand the sensing mechanism. The G-doped/p-Si gas sensor was synthesized by a simple capillary force-assisted solution dropping method on p-Si substrates, whose porosity was generated through an electrochemical etching process. G-doped/p-Si was fabricated with various graphene concentrations and exploited as a H2 sensor that was operated at room temperature. The sensing mechanism of the sensor with/without graphene decoration on p-Si was proposed to elucidate the synergetic gas sensing effect that is generated from the interface between the graphene and p-type silicon. PMID- 29182574 TI - Contribution of Dietary Supplements to Nutritional Adequacy in Race/Ethnic Population Subgroups in the United States. AB - The U.S. Centers for Disease Control and Prevention has reported that nutritional deficiencies in the U.S. population vary by age, gender, and race/ethnicity, and could be as high as nearly one third of certain population groups. Based on nationally representative data in 10,698 adults from National Health and Nutrition Examination Surveys (NHANES) primarily from 2009-2012, assessments were made of race/ethnic differences in the impact of dietary supplements on nutrient intake and prevalence of inadequacies. Compared to food alone, use of any dietary supplement plus food was associated with significantly higher intakes of 14 to 16 of 19 nutrients examined in all race/ethnic groups; and significantly (p < 0.01) reduced rates of inadequacy for 8/17 nutrients examined in non-Hispanic whites, but only 3-4/17 nutrients (calcium, and vitamins A, D, and E) for other race/ethnic groups. Across race/ethnic groups an increased prevalence of intakes above the Tolerable Upper Intake Level (UL) was seen for 1-9/13 nutrients, but all were less than 5% of the population. In conclusion, use of dietary supplements is associated with increased micronutrient intake, decreased nutrient inadequacies, and slight increases in prevalence above the UL in all race/ethnicities examined, with greater benefits among non-Hispanic whites.

AB - The effect of the addition of two [4-butyltrimethylammonium]-xylan chloride polyelectrolytes (BTMAXs) on bacterial cellulose (BC) was evaluated. The first strategy was to add the polyelectrolytes to the culture medium together with a cell suspension of the bacterium. After one week of cultivation, the films were collected and purified. The second approach consisted of obtaining a purified and homogenized BC, to which the polyelectrolytes were added subsequently. The films were characterized in terms of tear and burst indexes, optical properties, surface free energy, static contact angle, Gurley porosity, SEM, X-ray diffraction and AFM. Although there are small differences in mechanical and optical properties between the nanocomposites and control films, the films obtained by BC synthesis in the presence of BTMAXs were remarkably less opaque, rougher, and had a much lower specular gloss. The surface free energy depends on the BTMAXs addition method. The crystallinity of the composites is lower than that of the control material, with a higher reduction of this parameter in the composites obtained by adding the BTMAXs to the culture medium. In view of these results, it can be concluded that BC-BTMAX composites are a promising new material, for example, for paper restoration.

AB - : Nuts are often considered beneficial for health, yet few studies have examined determinants of their intake and the associations between nut consumption and various cardiovascular disease risk factors. The aim of this study was to identify factors associated with nut intake in a Mediterranean population, in Croatia, and to investigate the association of nut intake and various cardiovascular risk factors. METHODS: Subjects from the Island of Vis, Island of Korcula and the City of Split were included in this cross-sectional study (n = 4416 in total; 4011 without known cardiovascular disease). Survey responses, medical records and clinically relevant measurements were utilized. Multivariate ordinal and logistic regression models were used in the analysis, adjusting for known confounding factors. RESULTS: As low as 5% of all subjects reported daily, and 11% reported weekly, nut consumption. The characteristics associated with more frequent nut intake were female gender (Odds ratio (OR) = 1.39; 95% confidence interval (CI) 1.19-1.62), highest level of education (1.42; 1.15-1.76) and material status (1.58; 1.29-1.93), smoking abstinence (1.21; 1.04-1.42 in never-smokers and 1.22; 1.02-1.46 in ex-smokers), Mediterranean diet adherence (1.87; 1.62-2.15), and absence of central obesity (1.29; 1.09-1.53), absence of diabetes (1.30; 1.02-1.66) and metabolic syndrome (1.17; 1.01-1.36). Subjects who consumed nuts had more favorable waist-to-height (overall p = 0.036) and waist-to hip ratios (0.033), lesser odds of elevated fibrinogen (p < 0.001 in both weekly and monthly nut consumers) and reduced high-density lipoprotein (HDL) cholesterol (p = 0.026), compared to non-consumers. CONCLUSIONS: It appears that frequent nut consumption is an integral part of a healthy lifestyle and better socioeconomic status. A beneficial association of nut intake with cardiovascular risk factors was confirmed in this study.

AB - Schistosoma haematobium is a human blood fluke causing a chronic infection called urogenital schistosomiasis. Squamous cell carcinoma of the urinary bladder (SCC) constitutes chronic sequelae of this infection, and S. haematobium infection is accounted as a risk factor for this type of cancer. This infection is considered a neglected tropical disease and is endemic in numerous countries in Africa and the Middle East. Schistosome eggs produce catechol-estrogens. These estrogenic molecules are metabolized to active quinones that induce modifications in DNA. The cytochrome P450 (CYP) enzymes are a superfamily of mono-oxygenases involved in estrogen biosynthesis and metabolism, the generation of DNA damaging procarcinogens, and the response to anti-estrogen therapies. IL6 Interleukin-6 (IL-6) is a pleiotropic cytokine expressed in various tissues. This cytokine is largely expressed in the female urogenital tract as well as reproductive organs. Very high or very low levels of IL-6 are associated with estrogen metabolism imbalance. In the present study, we investigated the polymorphic variants in the CYP2D6 gene and the C-174G promoter polymorphism of the IL-6 gene on S. haematobium-infected children patients from Guine Bissau. CYP2D6 inactivated alleles (28.5%) and IL6G-174C (13.3%) variants were frequent in S. haematobium infected patients when compared to previously studied healthy populations (4.5% and 0.05%, respectively). Here we discuss our recent findings on these polymorphisms and whether they can be predictive markers of schistosome infection and/or represent potential biomarkers for urogenital schistosomiasis associated bladder cancer and infertility. PMID- 29182578 TI - Dietary Sialyllactose Influences Sialic Acid Concentrations in the Prefrontal Cortex and Magnetic Resonance Imaging Measures in Corpus Callosum of Young Pigs. AB - Sialic acid (SA) is a key component of gangliosides and neural cell adhesion molecules important during neurodevelopment. Human milk contains SA in the form of sialyllactose (SL) an abundant oligosaccharide. To better understand the potential role of dietary SL on neurodevelopment, the effects of varying doses of dietary SL on brain SA content and neuroimaging markers of development were assessed in a newborn piglet model. Thirty-eight male pigs were provided one of four experimental diets from 2 to 32 days of age. Diets were formulated to contain: 0 mg SL/L (CON), 130 mg SL/L (LOW), 380 mg SL/L (MOD) or 760 mg SL/L (HIGH). At 32 or 33 days of age, all pigs were subjected to magnetic resonance imaging (MRI) to assess brain development. After MRI, pig serum and brains were collected and total, free and bound SA was analyzed. Results from this study indicate dietary SL influenced (p = 0.05) bound SA in the prefrontal cortex and the ratio of free SA to bound SA in the hippocampus (p = 0.04). Diffusion tensor imaging indicated treatment effects in mean (p < 0.01), axial (p < 0.01) and radial (p = 0.01) diffusivity in the corpus callosum. Tract-based spatial statistics (TBSS) indicated differences (p < 0.05) in white matter tracts and voxel-based morphometry (VBM) indicated differences (p < 0.05) in grey matter between LOW and MOD pigs. CONT and HIGH pigs were not included in the TBSS and VBM assessments. These findings suggest the corpus callosum, prefrontal cortex and hippocampus may be differentially sensitive to dietary SL supplementation.

AB - Oxidative stress and neuroinflammation are implicated in the development and pathogenesis of Alzheimer's disease (AD). Here, we investigated the anti inflammatory and antioxidative effects of krill oil. Oil from Euphausia superba (Antarctic krill), an Antarctic marine species, is rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). We examined whether krill oil diet (80 mg/kg/day for one month) prevents amyloidogenesis and cognitive impairment induced by intraperitoneal lipopolysaccharide (LPS) (250 ug/kg, seven times daily) injections in AD mice model and found that krill oil treatment inhibited the LPS-induced memory loss. We also found that krill oil treatment inhibited the LPS-induced expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) and decreased reactive oxygen species (ROS) and malondialdehyde levels. Krill oil also suppresses IkappaB degradation as well as p50 and p65 translocation into the nuclei of LPS-injected mice brain cells. In association with the inhibitory effect on neuroinflammation and oxidative stress, krill oil suppressed amyloid beta (1-42) peptide generation by the down regulating APP and BACE1 expression in vivo. We found that eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (50 and 100 uM) dose-dependently decreased LPS-induced nitric oxide and ROS generation, and COX-2 and iNOS expression as well as nuclear factor-kappaB activity in cultured microglial BV-2 cells. These results suggest that krill oil ameliorated impairment via anti-inflammatory, antioxidative, and anti-amyloidogenic mechanisms. PMID- 29182580 TI - Genes and Gut Bacteria Involved in Luminal Butyrate Reduction Caused by Diet and Loperamide. AB - Unbalanced dietary habits and gut dysmotility are causative factors in metabolic and functional gut disorders, including obesity, diabetes, and constipation. Reduction in luminal butyrate synthesis is known to be associated with gut dysbioses, and studies have suggested that restoring butyrate formation in the colon may improve gut health. In contrast, shifts in different types of gut microbiota may inhibit luminal butyrate synthesis, requiring different treatments to restore colonic bacterial butyrate synthesis. We investigated the influence of high-fat diets (HFD) and low-fiber diets (LFD), and loperamide (LPM) administration, on key bacteria and genes involved in reduction of butyrate synthesis in mice. MiSeq-based microbiota analysis and HiSeq-based differential gene analysis indicated that different types of bacteria and genes were involved in butyrate metabolism in each treatment. Dietary modulation depleted butyrate kinase and phosphate butyryl transferase by decreasing members of the Bacteroidales and Parabacteroides. The HFD also depleted genes involved in succinate synthesis by decreasing Lactobacillus. The LFD and LPM treatments depleted genes involved in crotonoyl-CoA synthesis by decreasing Roseburia and Oscilllibacter. Taken together, our results suggest that different types of bacteria and genes were involved in gut dysbiosis, and that selected treatments may be needed depending on the cause of gut dysfunction. PMID- 29182581 TI - Harvesting a 3D N-Doped Carbon Network from Waste Bean Dregs by Ionothermal Carbonization as an Electrocatalyst for an Oxygen Reduction Reaction. AB - Three-dimensional nitrogen-doped carbon (3D-NCN) has been synthesized via the ionothermal carbonization method using waste soybean dregs (SD) as the precursor. N2 adsorption/desorption isotherms show that the as-prepared 3D-NCN formed a hierarchically porous structure with a specific BET surface area of 1093.4 m2 g-1 and a total pore volume of 1.77 cm3 g-1. The TEM images clearly show that graphene-like carbon sheets were formed on the edge of the networks. The characterization of the samples collected at different temperature indicated that salt melt plays the key role in the formation of the network structure and rich pores. When 3D-NCN is as electrocatalyst for ORR, it shows an onset potential of 0.945 V with a more positive half-wave potential (0.846 V), which is comparable to that of commercial Pt/C. In addition, the long-term cycle results show that the onset potential and half-wave potential only negatively shifted by 6 mV and 8 mV after 10,000 cycles respectively, which are smaller than those values of commercial Pt/C. Due to its high ORR activity, durability, and low-cost, producing 3D-NCN from SD in molten salt medium provides a promising approach to replace the Pt-based catalysts for use in fuel cells. PMID- 29182582 TI - New Half-Metallic Materials: FeRuCrP and FeRhCrP Quaternary Heusler Compounds. AB - The electronic structures and magnetic properties of FeRuCrP and FeRhCrP quaternary Heusler compounds with LiMgPbSb-type structures have been investigated via first-principles calculations. The calculational results show that both FeRuCrP and FeRhCrP compounds present perfect half-metallic properties: Showing large half-metallic band gaps of 0.39 eV and 0.38 eV, respectively. The total magnetic moments of FeRuCrP and FeRhCrP are 3 MUB and 4 MUB per formula unit, respectively. The magnetism of them mainly comes from the 3d electrons of Cr atoms and follows the Slater-Paulig behavior of Heusler compounds: Mt = Zt - 24. Furthermore, the half-metallic properties of FeRuCrP and FeRhCrP compounds can be kept in a quite large range of lattice constants (about 5.44-5.82 A and 5.26-5.86 A, respectively) and are quite robust against tetragonal deformation (c/a ratio in the range of 0.94-1.1 and 0.97-1.1, respectively). Moreover, the large negative cohesion energy and formation energy of FeRuCrP and FeRhCrP compounds indicate that they can be synthesized experimentally. PMID- 29182583 TI - trans-Double Bond-Containing Liposomes as Potential Carriers for Drug Delivery. AB - The use of liposomes has been crucial for investigations in biomimetic chemical biology as a membrane model and in medicinal chemistry for drug delivery. Liposomes are made of phospholipids whose biophysical characteristics strongly depend on the type of fatty acid moiety, where natural unsaturated lipids always have the double bond geometry in the cis configuration. The influence of lipid double bond configuration had not been considered so far with respect to the competence of liposomes in delivery. We were interested in evaluating possible changes in the molecular properties induced by the conversion of the double bond from cis to trans geometry. Here we report on the effects of the addition of trans-phospholipids supplied in different amounts to other liposome constituents (cholesterol, neutral phospholipids and cationic surfactants), on the size, zeta potential and stability of liposomal formulations and on their ability to encapsulate two dyes such as rhodamine B and fluorescein. From a biotechnological point of view, trans-containing liposomes proved to have different characteristics from those containing the cis analogues, and to influence the incorporation and release of the dyes. These results open new perspectives in the use of the unnatural lipid geometry, for the purpose of changing liposome behavior and/or of obtaining molecular interferences, also in view of synergic effects of cell toxicity, especially in antitumoral strategies. PMID- 29182584 TI - Adjuvant Biological Therapies in Chronic Leg Ulcers. AB - Current biological treatments for non-healing wounds aim to address the common deviations in healing mechanisms, mainly inflammation, inadequate angiogenesis and reduced synthesis of extracellular matrix. In this context, regenerative medicine strategies, i.e., platelet rich plasmas and mesenchymal stromal cell products, may form part of adjuvant interventions in an integral patient management. We synthesized the clinical experience on ulcer management using these two categories of biological adjuvants. The results of ten controlled trials that are included in this systematic review favor the use of mesenchymal stromal cell based-adjuvants for impaired wound healing, but the number and quality of studies is moderate-low and are complicated by the diversity of biological products. Regarding platelet-derived products, 18 controlled studies investigated their efficacy in chronic wounds in the lower limb, but the heterogeneity of products and protocols hinders clinically meaningful quantitative synthesis. Most patients were diabetic, emphasizing an unmet medical need in this condition. Overall, there is not sufficient evidence to inform routine care, and further clinical research is necessary to realize the full potential of adjuvant regenerative medicine strategies in the management of chronic leg ulcers. PMID- 29182585 TI - Optimization and Characterization of Paper-Made Surface Enhanced Raman Scattering (SERS) Substrates with Au and Ag NPs for Quantitative Analysis. AB - In this work, we present a systematic study on solid Surface Enhanced Raman Scattering (SERS) substrates consisting of Au and Ag nanoparticles (NPs) loaded on filter paper with the dip-coating method. The aim of this work is to explore how a series of parameters (e.g., concentration of colloidal solution, different porosity of filter paper, and the presence of an aggregating agent) affects the analytical performance of paper-based SERS substrates. All the substrates developed in this study have been analyzed with two non-resonant probe molecules, 4-mercaptobenzoic acid (4-MBA) and adenine, in terms of (i) inter-sample repeatability, (ii) intra-sample repeatability, (iii) sensitivity, and (iv) overall SERS performance in terms of analyte quantification. Moreover, the issue of how to evaluate the repeatability for a solid SERS substrate is carefully discussed.

AB - Thionines are recalcitrant and polluting textile dyes presenting various degrees of N-methylation. In this paper, a complete series of homologous thionines was used as the substrates for oxidation in the presence of a bioinspired commercial iron-porphyrin immobilized on to imidazole- and pyridine-functionalized fumed silica, to emulate the active site of ligninolytic peroxidases. The obtained catalytic adducts showed a remarkable ability to catalyze thionine dye oxidation in the presence of different oxidants such as potassium monopersulfate and hydrogen peroxide. Different oxidation patterns were obtained and mechanistically discussed, in comparison with those observed in the presence of some ligninolytic oxidizing enzymes. PMID- 29182589 TI - Radio-Frequency-Controlled Urea Dosing for NH3-SCR Catalysts: NH3 Storage Influence to Catalyst Performance under Transient Conditions. AB - Current developments in exhaust gas aftertreatment led to a huge mistrust in diesel driven passenger cars due to their NOx emissions being too high. The selective catalytic reduction (SCR) with ammonia (NH3) as reducing agent is the only approach today with the capability to meet upcoming emission limits. Therefore, the radio-frequency-based (RF) catalyst state determination to monitor the NH3 loading on SCR catalysts has a huge potential in emission reduction. Recent work on this topic proved the basic capability of this technique under realistic conditions on an engine test bench. In these studies, an RF system calibration for the serial type SCR catalyst Cu-SSZ-13 was developed and different approaches for a temperature dependent NH3 storage were determined. This paper continues this work and uses a fully calibrated RF-SCR system under transient conditions to compare different directly measured and controlled NH3 storage levels, and NH3 target curves. It could be clearly demonstrated that the right NH3 target curve, together with a direct control on the desired level by the RF system, is able to operate the SCR system with the maximum possible NOx conversion efficiency and without NH3 slip.

AB - We describe the synthesis, reactivity, and antithrombotic and anti-angiogenesis activity of difluoroallicin (S-(2-fluoroallyl) 2-fluoroprop-2-ene-1 sulfinothioate) and S-2-fluoro-2-propenyl-l-cysteine, both easily prepared from commercially available 3-chloro-2-fluoroprop-1-ene, as well as the synthesis of 1,2-bis(2-fluoroallyl)disulfane, 5-fluoro-3-(1-fluorovinyl)-3,4-dihydro-1,2 dithiin, trifluoroajoene ((E,Z)-1-(2-fluoro-3-((2-fluoroallyl)sulfinyl)prop-1-en 1-yl)-2-(2-fluoroallyl)disulfane), and a bis(2-fluoroallyl)polysulfane mixture. All tested organosulfur compounds demonstrated effective inhibition of either FGF or VEG-mediated angiogenesis (anti-angiogenesis activity) in the chick chorioallantoic membrane (CAM) or the mouse Matrigel(r) models. No embryo mortality was observed. Difluoroallicin demonstrated greater inhibition (p < 0.01) versus organosulfur compounds tested. Difluoroallicin demonstrated dose dependent inhibition of angiogenesis in the mouse Matrigel(r) model, with maximal inhibition at 0.01 mg/implant. Allicin and difluoroallicin showed an effective antiplatelet effect in suppressing platelet aggregation compared to other organosulfur compounds tested. In platelet/fibrin clotting (anti-coagulant activity), difluoroallicin showed concentration-dependent inhibition of clot strength compared to allicin and the other organosulfur compounds tested.

(M. charantia), a member of the Cucurbitaceae family, is widely distributed in tropical and subtropical regions of the world. It has been used in folk medicine for the treatment of diabetes mellitus, and its fruit has been used as a vegetable for thousands of years. Phytochemicals including proteins, polysaccharides, flavonoids, triterpenes, saponins, ascorbic acid and steroids have been found in this plant. Various biological activities of M. charantia have been reported, such as antihyperglycemic, antibacterial, antiviral, antitumor, immunomodulation, antioxidant, antidiabetic, anthelmintic, antimutagenic, antiulcer, antilipolytic, antifertility, hepatoprotective, anticancer and anti-inflammatory activities. However, both in vitro and in vivo studies have also demonstrated that M. charantia may also exert toxic or adverse effects under different conditions. This review addresses the chemical constituents of M. charantia and discusses their pharmacological activities as well as their adverse effects, aimed at providing a comprehensive overview of the phytochemistry and biological activities of M. charantia. PMID- 29182591 TI - ECG Signal De-noising and Baseline Wander Correction Based on CEEMDAN and Wavelet Threshold. AB - A novel electrocardiogram (ECG) signal de-noising and baseline wander correction method based on complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) and wavelet threshold is proposed. Although CEEMDAN is based on empirical mode decomposition (EMD), it represents a significant improvement of the original EMD by overcoming the mode-mixing problem. However, there has been no previous study on using CEEMDAN to de-noise ECG signals, to the authors' best knowledge. In the proposed method, the original noisy ECG signal is decomposed into a series of intrinsic mode functions (IMFs) sorted from high to low frequency by CEEMDAN. Each IMF is then analyzed by the autocorrelation method to find out the first few high frequency IMFs containing random noise, and these IMFs should be de-noised by the wavelet threshold. The zero-crossing rate (ZCR) of all IMFs, including final residue, are computed, and the IMFs with ZCR less than a certain value are removed. Finally, the remaining IMFs are reconstructed to obtain the clean ECG signal. The proposed algorithm is validated through experiments using the MIT-BIH ECG databases, and the results show that the random noise in the ECG signal can be effectively suppressed, and at the same time the baseline wander can be corrected efficiently. PMID- 29182590 TI - Study on the Prevalence of Severe Anemia among Non-Pregnant Women of Reproductive Age in Rural China: A Large Population-Based Cross-Sectional Study. AB - Globally, severe anemia impacts millions of non-pregnant women. However, studies on the prevalence of severe anemia through large epidemiologic surveys among non pregnant women have been scarce in China. In this study, we aimed to study the prevalence of severe anemia and its determinants among non-pregnant women living in rural areas of China. Data were gathered for 712,101 non-pregnant women aged between 21 and 49 years who attended the 2012 National Free Preconception Health Examination Project. Severe anemia in non-pregnant women was defined as a hemoglobin (Hb) concentration lower than 80 g/L. Associated factors were analyzed using univariate and multivariate logistic regression methods. Out of the 712,101 non-pregnant women living in the rural areas of China, 1728 suffered from severe anemia, with a prevalence of 0.24% (95% confidence interval (CI): 0.23-0.25%). Results from the multivariable logistic regression showed that elderly (adjusted odds ratio (aOR) = 3.08), living in the northwest region (aOR = 2.88), having a history of anemia (aOR = 5.76), with heavy menstrual blood loss (aOR = 1.84), and with a history of using an intra-uterine device (aOR = 1.47) etc., were independent determinants for women with severe anemia in rural China. The prevalence of severe anemia among Chinese non-pregnant women living in the rural areas was lower than the reported global prevalence. Prevention and intervention programs for severe anemia are required among non-pregnant women of reproductive age in the rural areas of China. PMID- 29182592 TI - A Novel Adaptive Hinfinity Filtering Method with Delay Compensation for the Transfer Alignment of Strapdown Inertial Navigation Systems. AB - Transfer alignment is always a key technology in a strapdown inertial navigation system (SINS) because of its rapidity and accuracy. In this paper a transfer alignment model is established, which contains the SINS error model and the measurement model. The time delay in the process of transfer alignment is analyzed, and an Hinfinity filtering method with delay compensation is presented. Then the Hinfinity filtering theory and the robust mechanism of Hinfinity filter are deduced and analyzed in detail. In order to improve the transfer alignment accuracy in SINS with time delay, an adaptive Hinfinity filtering method with delay compensation is proposed. Since the robustness factor plays an important role in the filtering process and has effect on the filtering accuracy, the adaptive Hinfinity filter with delay compensation can adjust the value of robustness factor adaptively according to the dynamic external environment. The vehicle transfer alignment experiment indicates that by using the adaptive Hinfinity filtering method with delay compensation, the transfer alignment accuracy and the pure inertial navigation accuracy can be dramatically improved, which demonstrates the superiority of the proposed filtering method.

PMID- 29182595 TI - Identifying Patients Who Will Most Benefit from Single Photon Emission Computerized Tomography and Computerized Tomography After Femoral Neck Fracture. AB - BACKGROUND Single photon emission computerized tomography and computerized tomography (SPECT/CT) is useful for assessing blood supply within the femoral head after femoral neck fracture, but its use in all femoral neck fracture patients is not feasible. Therefore, the present study aimed to identify the patients for whom SPECT/CT examination will be most beneficial. MATERIAL AND METHODS Sixty-five patients with a unilateral femoral neck fracture who underwent SPECT/CT examination of the hip and were treated via closed reduction and internal fixation with three screws were enrolled between January 2009 and March 2011. A decision tree model (C 5.0) was used to identify the factors that best reflect blood supply and to build a flowchart for identifying patients who would benefit from SPECT/CT. RESULTS Fracture type was most strongly associated with the Fracture/Normal (F/N) ratio, which reflects the blood supply to the fractured femoral head. Age and the time interval from injury to examination were also associated with the F/N ratio. SPECT/CT examination is most beneficial for patients with a displaced fracture, especially if they are over 58 years old and the time interval from injury to examination is less than 10 days. CONCLUSIONS Our results indicate that elderly people with a displaced fracture are most likely to benefit from SPECT/CT examination, which can show the blood supply to the femoral head within a relatively short window of time after the injury.

AB - The necessary precondition for efficient boron neutron capture therapy (BNCT) is control over the content of isotope 10B in the tumor and normal tissues. In the case of boron-containing porphyrins, the fluorescent part of molecule can be used for quantitative assessment of the boron content. Study Objective: We performed a study of the biodistribution of the chlorin e6-Cobalt bis(dicarbollide) conjugate in carcinoma-bearing Balb/c mice using ex vivo fluorescence imaging, and developed a mathematical model describing boron accumulation and release based on the obtained experimental data. Materials and Methods: The study was performed on Balb/c tumor-bearing mice (CT-26 tumor model). A solution of the chlorin e6 Cobalt bis(dicarbollide) conjugate (CCDC) was injected into the blood at a dose of 10 mg/kg of the animal's weight. Analysis of the fluorescence signal intensity was performed at several time points by spectrofluorimetry in blood and by laser scanning microscopy in muscle, liver, and tumor tissues. The boron content in the same samples was determined by mass spectroscopy with inductively coupled plasma. Results: Analysis of a linear approximation between the fluorescence intensity and boron content in the tissues demonstrated a satisfactory value of approximation reliability with a Spearman's rank correlation coefficient of r = 0.938, p < 0.01. The dynamics of the boron concentration change in various organs, calculated on the basis of the fluorescence intensity, enabled the development of a model describing the accumulation of the studied compound and its distribution in tissues. The obtained results reveal a high level of correspondence between the model and experimental data.

The objectives were to describe the data merging process of the 2006/07 and 2011/12 SHS editions, as well as to provide the merged databases and the directory of the variables. METHODS: The comparable variables were identified from the questionnaires. Other new variables were created to achieve comparability or to provide new indicators of interest. We obtained two completed merged databases, as well as two variable directories with their dictionaries (each one for the adults and children samples). RESULTS: 188 variables were identified as potentially comparable ones. 36,7% of them had difficulties for being comparable and 8% had to be removed. The topic with the worst consequences due to the lack of comparability was the working conditions and employment from the adult sample. CONCLUSIONS: The merging of both SHS editions had a lot of problems, especially in the adult's sample. That affects to its comparability. This work may be useful to assess, design and merge these and other editions of the SHS, as well as to serve as a model to be applied in other cross-sectional population-based surveys.

The objective was to determine and describe the OI in the Valencia Region (VR) during the period 2004 to 2014. METHODS: From the Rare Diseases Information System of the VR (SIER CV) patients from 2004 to 2014 with the codes of the International Classification of Diseases for the OI were identified: 756.51 from the 9th Revision-Clinical Modification and Q78.0 from the 10th Revision. The information was validated by reviewing clinical documentation (mainly electronic health records) and a descriptive analysis of the confirmed cases (diagnosis of OI in the clinical documentation) was performed. RESULTS: 162 patients were identified with a code for OI. 145 of the 161 patients with available clinical documentation were confirmed as cases. The prevalence was 0.29 per 10.000 inhabitants. 93.1% were Spanish, 54.5% were women and they were treated in 25 different hospitals in the VR. The type of OI was known in the 26.4% of the cases and type I was the most common (9.7%). 6.2% of the patients died with an average death age of 60.8 years. 44.8% of patients received treatment with bisphosphonates and 10.4% had affected relatives. CONCLUSIONS: The real situation of the OI in the VR has been established, which will allow a better planning in the health actions to improve the quality of life of the affected ones and their families.

What makes the dataset unique is the fact that it contains demographic data together with aggregated clickstream data of students' interactions in the Virtual Learning Environment (VLE). This enables the analysis of student behaviour, represented by their actions. The dataset contains the information about 22 courses, 32,593 students, their assessment results, and logs of their interactions with the VLE represented by daily summaries of student clicks (10,655,280 entries). The dataset is freely available at https://analyse.kmi.open.ac.uk/open_dataset under a CC-BY 4.0 license. PMID- 29182598 TI - Monitoring transcription initiation activities in rat and dog. AB - The promoter landscape of several non-human model organisms is far from complete. As a part of FANTOM5 data collection, we generated 13 profiles of transcription initiation activities in dog and rat aortic smooth muscle cells, mesenchymal stem cells and hepatocytes by employing CAGE (Cap Analysis of Gene Expression) technology combined with single molecule sequencing. Our analyses show that the CAGE profiles recapitulate known transcription start sites (TSSs) consistently, in addition to uncover novel TSSs. Our dataset can be thus used with high confidence to support gene annotation in dog and rat species. We identified 28,497 and 23,147 CAGE peaks, or promoter regions, for rat and dog respectively, and associated them to known genes. This approach could be seen as a standard method for improvement of existing gene models, as well as discovery of novel genes. Given that the FANTOM5 data collection includes dog and rat matched cell types in human and mouse as well, this data would also be useful for cross species studies. PMID- 29182600 TI - RE-Europe, a large-scale dataset for modeling a highly renewable European electricity system. AB - Future highly renewable energy systems will couple to complex weather and climate dynamics. This coupling is generally not captured in detail by the open models developed in the power and energy system communities, where such open models exist. To enable modeling such a future energy system, we describe a dedicated large-scale dataset for a renewable electric power system. The dataset combines a transmission network model, as well as information for generation and demand. Generation includes conventional generators with their technical and economic characteristics, as well as weather-driven forecasts and corresponding realizations for renewable energy generation for a period of 3 years. These may be scaled according to the envisioned degrees of renewable penetration in a future European energy system. The spatial coverage, completeness and resolution of this dataset, open the door to the evaluation, scaling analysis and replicability check of a wealth of proposals in, e.g., market design, network actor coordination and forecasting of renewable power generation.

PMID- 29182603 TI - A psychosocial approach to female genital pain. AB - Genital pain is a prevalent, complex, and disabling health concern in women. Efforts to study this chronic pain condition have been complicated by the fact that genital pain is heterogeneous and exists at the intersection of different biopsychosocial disciplines. Thus, organization of theoretical ideas and empirical findings across research areas is required to improve our understanding of how biopsychosocial factors affect the development and maintenance of the pain, the reporting of symptoms, and the choice of treatment. In the past, the study of physical markers has received the most research attention; an assimilation of the psychosocial variables underlying genital pain is, therefore, particularly needed to inform the field about the rapidly growing literature and stimulate interdisciplinary work. Current research lacks specificity, fails to capture the unique features of different pain conditions, and yields conflicting evidence, which makes it difficult to draw uniform conclusions. Although considerable advances have been made, confusion remains at the nosological, aetiological, theoretical, methodological, and treatment levels. This lack of consensus has important theoretical and clinical implications because inconsistent criteria and empirical disagreement can lead to misdiagnoses and interfere with the development of sound theoretical models and effective treatments to manage female genital pain and its physical and psychological sequelae. PMID- 29182607 TI - The current state of funded NIH grants in implementation science in genomic medicine: a portfolio analysis. AB - PurposeImplementation science offers methods to evaluate the translation of genomic medicine research into practice. The extent to which the National Institutes of Health (NIH) human genomics grant portfolio includes implementation science is unknown. This brief report's objective is to describe recently funded implementation science studies in genomic medicine in the NIH grant portfolio, and identify remaining gaps.MethodsWe identified investigator-initiated NIH research grants on implementation science in genomic medicine (funding initiated 2012-2016). A codebook was adapted from the literature, three authors coded grants, and descriptive statistics were calculated for each code.ResultsForty-two grants fit the inclusion criteria (~1.75% of investigator-initiated genomics grants). The majority of included grants proposed qualitative and/or quantitative methods with cross-sectional study designs, and described clinical settings and primarily white, non-Hispanic study populations. Most grants were in oncology and examined genetic testing for risk assessment. Finally, grants lacked the use of implementation science frameworks, and most examined uptake of genomic medicine and/or assessed patient-centeredness.ConclusionWe identified large gaps in implementation science studies in genomic medicine in the funded NIH portfolio over the past 5 years. To move the genomics field forward, investigator-initiated research grants should employ rigorous implementation science methods within diverse settings and populations.Genetics in Medicine advance online publication, 26 October 2017; doi:10.1038/gim.2017.180. PMID- 29182608 TI - Impact of tumour histology on survival in advanced cervical carcinoma: an NRG Oncology/Gynaecologic Oncology Group Study. AB - BACKGROUND: Based primarily on studies concerning early-stage tumours (treated surgically), and locally advanced disease (treated with chemoradiation), the prognosis for women with adenocarcinoma (AC) or adenosquamous (AS) carcinoma has been reported to be poorer than those with squamous cell carcinoma (SCCA) of the cervix. It is unclear whether differences in prognosis also persist in the setting of recurrent or metastatic disease treated using chemotherapy doublets with or without bevacizumab. METHODS: Cases were pooled from three Gynaecologic Oncology Group randomised phase III trials of chemotherapy doublets. Pearson's test was used to evaluate response rate (RR) of AC/AS vs SCCA, Kaplan-Meier method to estimate progression-free survival (PFS) and overall survival (OS), and Cox proportional hazards model to estimate the impact of histology on PFS and OS. RESULTS: Of 781 evaluable patients, 77% (N=599) had SCCA and 23% (N=182) AC/AS. There were no significant differences in RRs between histologic subgroups. The adjusted hazard ratio (HR) for death for SCCA vs AC/AS was 1.13 (95% CI 0.93, 1.38 P=0.23). When comparing SC/AS (N=661, 85%) to AC alone (N=120, 15%), the adjusted HR for death was 1.23 (95% CI 0.97, 1.57, P=0.09). CONCLUSIONS: AC/AS and SCCA have similar survival in recurrent or metastatic cervical carcinoma when treated with chemotherapy doublets. PMID- 29182610 TI - BDNF expression in cat striate cortex is regulated by binocular pattern deprivation. AB - Deprivation of patterned visual information, as in early onset congenital cataract patients, results in a severe impairment in global motion perception. Previously we reported a delayed maturation of the peripheral visual field representation in primary visual area 17, based on a 2-D DIGE screen for protein expression changes and in situ hybridization for the activity reporter gene ZIF268. To corroborate these findings we here explore the binocular pattern deprivation (BD)-regulated expression of brain-derived neurotrophic factor (BDNF), a well-described neurotrophin precipitously regulated by early visual experience. To assess the timing of maturation-related BDNF expression we compared the central and the peripheral visual field representations of area 17 of 1, 2, 4 and 6-month-old and adult cats reared under normal visual conditions. To scrutinize the outcome of BD, four different deprivation strategies were compared, including early onset BD from birth and lasting for 2, 4 or 6 months (2BD, 4BD, 6BD), and late onset BD for 2 months upon 2 months of normal vision (2N2BD), as animal models of congenital and delayed onset cataract. During normal cortical development the BDNF transcript levels, measured by quantitative RT-PCR, remained stable. Higher BDNF mRNA levels were found in central area 17 of 2BD and 6BD animals compared to age-matched controls. In central area 17, the high BDNF mRNA levels at the end of the BD period may activate a mechanism by which plastic processes, halted by deprivation, may begin. We here confirm that the peripheral visual field representation of area 17 matures slower than its central counterpart. Only in central area 17 normal visual input upon BD could upregulate BDNF mRNA which may lead to a fast activation of local plastic adaptations. PMID- 29182609 TI - Variation in 'fast-track' referrals for suspected cancer by patient characteristic and cancer diagnosis: evidence from 670 000 patients with cancers of 35 different sites. AB - BACKGROUND: In England, 'fast-track' (also known as 'two-week wait') general practitioner referrals for suspected cancer in symptomatic patients are used to shorten diagnostic intervals and are supported by clinical guidelines. However, the use of the fast-track pathway may vary for different patient groups. METHODS: We examined data from 669 220 patients with 35 cancers diagnosed in 2006-2010 following either fast-track or 'routine' primary-to-secondary care referrals using 'Routes to Diagnosis' data. We estimated the proportion of fast-track referrals by sociodemographic characteristic and cancer site and used logistic regression to estimate respective crude and adjusted odds ratios. We additionally explored whether sociodemographic associations varied by cancer. RESULTS: There were large variations in the odds of fast-track referral by cancer (P<0.001). Patients with testicular and breast cancer were most likely to have been diagnosed after a fast-track referral (adjusted odds ratios 2.73 and 2.35, respectively, using rectal cancer as reference); whereas patients with brain cancer and leukaemias least likely (adjusted odds ratios 0.05 and 0.09, respectively, for brain cancer and acute myeloid leukaemia). There were sex, age and deprivation differences in the odds of fast-track referral (P<0.013) that varied in their size and direction for patients with different cancers (P<0.001). For example, fast-track referrals were least likely in younger women with endometrial cancer and in older men with testicular cancer. CONCLUSIONS: Fast track referrals are less likely for cancers characterised by nonspecific presenting symptoms and patients belonging to low cancer incidence demographic groups. Interventions beyond clinical guidelines for 'alarm' symptoms are needed to improve diagnostic timeliness. PMID- 29182611 TI - The differential effects of neuroleptic drugs and PACAP on the expression of BDNF mRNA and protein in a human glioblastoma cell line. AB - Despite numerous studies, the molecular mechanisms underpinning the action of antipsychotic drugs remain not fully understood. It has been suggested that, in addition to the modulation of monoaminergic neurotransmission, antipsychotic drugs can also affect the expression of neurotrophic factors in the brain. The present study examines the effects of a first-generation neuroleptic drug (FGA; haloperidol) and two second-generation neuroleptic drugs (SGAs; olanzapine and amisulpride) on the expression and levels of brain-derived neurotrophic factor (BDNF) in an astrocyte-like T98G glioblastoma cell line. The effects of these drugs were compared to the action of PACAP38, a neuropeptide with well-known BDNF mediated neuroprotective effects. The tested neuroleptics differentially regulated the mRNA expression and protein level of BDNF depending on concentration and incubation time. Real-time PCR analysis demonstrates that, of the three tested neuroleptics, both haloperidol and olanzapine at a concentration of 5 uM (but not at 20 uM) increased BDNF mRNA expression with similar efficacy after 72-hour incubation. In order to confirm the observed changes in the mRNA expression of BDNF, a protein expression assay was performed. The exposure of cells to 5 MUM olanzapine alone for 72 hours increased BDNF concentration in the culture medium by 29%. Additionally, PACAP significantly up-regulated BDNF mRNA expression in T98G cells and the obtained results correlated positively with the increased production of BDNF protein, 22% above control values. Our findings show that olanzapine, similarly to exogenous PACAP38, increased BDNF mRNA expression and protein release, which can contribute to its neuroprotective mechanism of action in the cells of non-neuronal origin. The results of the paper show that olanzapine, similarly to exogenous PACAP38, increased BDNF mRNA expression and protein release, which can contribute to its neuroprotective mechanism of action in the cells of nonneuronal origin. The results of the present paper confirm the findings that BDNF may represent the key target for olanzapine and PACAP. PMID- 29182612 TI - Nucleus accumbens local field potential power spectrums, phase-amplitude couplings and coherences following morphine treatment. AB - In the past decade, neural processing has been extensively studied in cognitive neuroscience. However, neural signaling in the nucleus accumbens (NAc) that might clarify reward process remained to be investigated. Male Swiss albino ICR mice implanted with intracranial electrodes into the NAc and the ventral tegmental area (VTA) were used for morphine administration and local field potential (LFP) recording. One-way ANOVA revealed significant increases in low (30.3-44.9 Hz) and high (60.5-95.7 Hz) gamma powers in the NAc following morphine administration (5 and 15 mg/kg, i.p.). These gamma activities oscillated independently with different time-course responses. Locomotor activity was also significantly increased by morphine administration. Regression analyses revealed that high gamma activity induced by morphine was positively correlated with distance travelled by animals. Low and high gamma powers were completely abolished by injection of naloxone, a non-specific opiate antagonist. Analysis of phase amplitude coupling confirmed that slow oscillations at 1-4 Hz (delta) and 4-8 Hz (theta) for phase were found to significantly increase modulation index of broad (30.27-80.77 Hz) and narrow (59.48-70.34 Hz) frequency ranges for amplitude, respectively. Moreover, significant increases in coherence values between the NAc and the VTA during 30-40 min following morphine administration were seen for 22.46-44.90 Hz frequency range. Altogether, this study demonstrated changes of LFP oscillations in the NAc with low and high gamma activities, delta- and theta gamma couplings and interplay with VTA in response to morphine administration. These findings represent neural signaling in the mesolimbic dopamine pathway that might process reward function. PMID- 29182613 TI - Assessment of type 1 and type 3 deiodinase expression levels in depressive disorders. AB - A depressive disorder is a disease characterized by a heterogenous background. The important processes observed and diagnosed in depressed patients indicate that the etiology of depression may include disturbances in thyroid hormone (TH) levels and the occurrence of immune-inflammatory activation. Type 1 (DIO1) and type 3 (DIO3) iodothyronine deiodinases are the enzymes which determine the peripheral and tissue levels of TH, but also interfere with immunological cells and inflammatory processes. We aimed to investigate the levels of DIO1 and DIO3 in the patients suffering from recurrent depressive disorders (rDD). Data collected from 91 rDD patients and 105 healthy controls were analyzed. The diagnoses were made based on the ICD-10 criteria (F33.0-F33.8). The expression levels of DIO1 and DIO3 were estimated using the polymerase chain reaction method and the enzyme-linked immunosorbent assay (ELISA). The expression of DIO1 on mRNA/protein levels in the rDD patients was reduced in comparison to the control subjects, while the expression of DIO3 was higher in the patients suffering from depression. No significant relationship was found between the investigated DIOs and other clinical parameters. Our results indicate and suggest a role of DIO1 and DIO3-related pathways in the pathophysiology of depression. The results represent a promising way to investigate the biological markers of depression. PMID- 29182614 TI - Tiapride prevents the aversive but not the rewarding effect induced by parabrachial electrical stimulation in a place preference task. AB - The parabrachial complex has been related to the processing of both rewarding and aversive signals. This pontine area is activated after the gastrointestinal administration of rewarding nutrients, in taste aversion learning, and in response to the reinforcing and aversive effects of some drugs of abuse. Electrical stimulation of this region can induce, in different animals, preference or aversion behaviors towards a place in a rectangular three-chamber maze task. This study examined the effect of tiapride, a D2/D3 receptor antagonist, on the aversive or rewarding effects induced by electrical stimulation of the external lateral parabrachial subnucleus (NLPBe). As previously observed, administration of tiapride interrupted the aversive effect induced by NLPBe electrical stimulation. However, in contrast to the effects of dopamine antagonists on other rewarding systems, tiapride did not impair the place preference induced by NLPBe stimulation, an activation effect that is subject to tolerance. Tiapride administration also appeared to have no effect on the horizontal motor activity (crossings) of the electrically stimulated animals. We discuss the specific relevance of parabrachial reward with respect to other reinforcing brain components or systems, especially in relation to the preference effect of drugs of abuse, such as opiates, after dopamine antagonist administration. PMID- 29182615 TI - Effects of individual stressors used in a battery of "chronic unpredictable stress" on long-term plasticity in the hippocampus of juvenile rats. AB - We have studied alterations in the properties of long-term potentiation (LTP) in hippocampal slices of juvenile rats induced by the exposure of animals to different individual stressors usually used in batteries of chronic unpredictable stress (CUS), a widely used model of depression. Social isolation for 16 h did substantially affect neither the magnitude and nor the development of LTP. The effects of stroboscopic illumination and water deprivation appeared most severe, though opposite: the first stressor had activating effect, whereas the second one inhibited the development of LTP. In addition to the effects of these factors on the LTP magnitude, they also affected the patterns of LTP development. In this study weak tetanization with different probability of maintenance was used, and most of stressors, in spite of the similar LTP magnitude, influenced significantly on the process of consolidation. In hippocampal slices from rats maintained on wet bedding for 16 h, the time course but not magnitude of LTP significantly differed from that observed in the control or socially isolated rats. The weakest effect on LTP was observed in hippocampal slices of the rats exposed to food deprivation. In these animals, only some differences were observed in the development of LTP as compared to socially isolated rats. These data allow ranging stressors used in CUS paradigms according to the severity of their potential effects on neuronal function and animal behavior. PMID- 29182616 TI - Marble burying as compulsive behaviors in male and female mice. AB - Marble burying is considered an, albeit controversial, animal model of the compulsive like behaviors of obsessive-compulsive disorder (OCD). Hallmark features of OCD patients are similarities and, more prominent, differences from anxiety disorders, e.g., the absence of sex differences and resistance to spontaneous remission. We report an experiment on marble burying by male and female C57/BL6/N mice. Animals were administered either the classic anxiolytic drug, diazepam, that targets the GABA receptor or a "pure" inhibitor of the serotonin transporter, escitalopram, that has been reported to be particularly effective in OCD. A burying paradigm that more precisely mimics the human condition was used, e.g., testing in the home environment, chronic drug exposure and acknowledging individual differences by pre-selecting for high marble burying. Results were that there were no sex differences in groups treated with drugs or in control mice. Both diazepam and escitalopram decreased numbers of marbles buried compared to vehicle-only controls in the absence of correlated changes in anxiety. Diazepam, however, was more effective than escitalopram in suppressing MB. The conclusion is that along with serotonin, GABA is involved in regulating compulsive behaviors. The marble burying paradigm may prove more useful for pharmacological drugs tests of impulsivity or attention deficit because of the involvement of serotonin and GABA in both disorders. PMID- 29182617 TI - In vivo stimulation of locus coeruleus: effects on amygdala subnuclei. AB - The locus coeruleus (LC) is the major noradrenergic nucleus and sends projections to almost all brain areas. A marked increase in norepinephrine release has been demonstrated in several brain areas in response to exposure to acute stressful stimuli, especially those innervated by LC projections. One of the brain areas innervated by LC neurons is the amygdala, a structure highly involved in emotional processes and memory formation. The aim of this study was to increase knowledge of the functional connectivity between the LC and the amygdala subnuclei. To reach this objective, we evaluated c-fos immunoreactive cells in amygdala nuclei following direct electrical stimulation of the LC in conscious animals. This analysis of c-Fos immunoreactivity could inform whether there are differences in activity of the amygdala subnuclei related to LC electrical stimulation in conscious animals. Our results showed a marked increase in c-fos activity in these amygdala subnuclei both ipsilateral and contralateral to LC electrical stimulation in vivo. Therefore, our study provides evidence that in vivo electrical stimulation of LC is able to activate the amygdala subnuclei as measured by c-fos expression. PMID- 29182618 TI - Impact of scale of aggregation on associations of cardiovascular hospitalization and socio-economic disadvantage. AB - BACKGROUND: There are numerous studies that show an increased incidence of cardiovascular disease with increasing levels of socio-economic disadvantage. Exposures that might influence the relationship include elements of the built environment and social systems that shape lifestyle risk behaviors. In Canberra (the Australian capital city) there has been a particular housing policy to create 'mixed-tenure' neighborhoods so that small pockets of disadvantage are surrounded by more affluent residences (known as a 'salt-and-pepper' pattern). This may contribute to a scatter of higher incidence rates in very small areas in this population that may be obscured if aggregated data are used. This study explored the effect of changing the scale of the spatial units used in small area disease modelling, aiming to understand the impact of this issue and the implications for local public health surveillance. METHODS: The residence location of hospitalized individuals were aggregated to two differently scaled area units. First, the Australian Bureau of Statistics Statistical Area 2 (SA2) which is normally used as the basis for deidentification and release of health data. Second, these data were aggregated to a smaller level: the Statistical Area 1 (SA1). Generalized Additive Models with penalized regression splines were used to assess the association of age-sex-standardized rates for cardiovascular disease hospital admissions with disadvantage. RESULTS: The relationships observed were different between the two types of spatial units. The SA1 level exposure-response curve for rates against the disadvantage index extended in a linear fashion above the midrange level, while that found at SA2-level suggested a curvilinear form with no evidence that rates increased with higher disadvantage beyond the midrange. CONCLUSION: Our result supports findings of other work that has found disadvantage increases risk of cardiovascular disease. The shape of the curves suggest a difference in associations of cardiovascular disease rates with disadvantage scores between SA1 versus SA2. From these results it can be concluded that scale of analysis does influence the understanding of geographical patterns of socio-economic disadvantage and cardiovascular disease morbidity. Health surveillance and interventions in Canberra should take into account the impact of the scale of aggregation on the association between disadvantage and cardiovascular disease observed. PMID- 29182619 TI - Response of imported malaria patients to antimalarial medicines in Sri Lanka following malaria elimination. AB - After eliminating local malaria transmission and being certified as a malaria free country, Sri Lanka is facing the challenge of imported malaria. At the same time, the country has the unique opportunity to be a case study for other countries in a similar situation by approaching this issue systematically, guided by evidence. This study demonstrates the importance of developing a mechanism to detect imported malaria and adopting an evidence-based approach to study the resistance of imported malaria to anti-malarial medicines. This is a prospective study of patients diagnosed with imported malaria in Sri Lanka and treated according to the national treatment guidelines, over 24 months (2015/2016). The clinical features, time to diagnosis, origin of the infection, infecting species, parasite density and the treatment given were recorded. All patients were followed up for 28 days, and in the case of Plasmodium vivax and P. ovale infections, the follow up period was extended to 12 months to establish treatment failures and relapses. Fifty nine uncomplicated and 15 severe imported malaria cases were reported in Sri Lanka during the study period. Most of these infections originated in either Sub-Saharan Africa or South and Southeast Asia. Having a P. vivax infection and low parasitic counts were significantly associated with relative diagnostic delay. One of the 14 uncomplicated P. falciparum patients and two of the 12 severe P. falciparum malaria patients who were followed up till day 28 had a late clinical failure. The others responded adequately to treatment both clinically and parasitologically. There was no treatment failure reported amongst any other species. This study, which is the first to assess the therapeutic response of imported malaria in Sri Lanka after elimination, demonstrates that the current antimalarial treatment policies and strategies in Sri Lanka have been effective against infections acquired overseas up until the end of year 2016. PMID- 29182620 TI - Broncho Vaxom (OM-85) modulates rhinovirus docking proteins on human airway epithelial cells via Erk1/2 mitogen activated protein kinase and cAMP. AB - BACKGROUND: Bronchial epithelial cells (BEC) are primary target for Rhinovirus infection through attaching to cell membrane proteins. OM-85, a bacterial extract, improves recovery of asthma and COPD patients after viral infections, but only part of the mechanism was addressed, by focusing on defined immune cells. OBJECTIVE: We therefore determined the effect of OM-85 on isolated primary human BEC of controls (n = 8), asthma patients (n = 10) and COPD patients (n = 9). METHODS: BEC were treated with OM-85 alone (24 hours) or infected with Rhinovirus. BEC survival was monitored by manual cell counting and Rhinovirus replication by lytic activity. Immuno-blotting and ELISA were used to determine the expression of Rhinovirus interacting proteins: intracellular adhesion molecule (ICAM), major histocompatibility complex class II (MHC-2), complement component C1q receptor (C1q-R), inducible T-Cell co-stimulator (ICOS), its ligand ICOSL, and myeloid differentiation primary response gene 88 (Myd88); as well as for signal transducers Erk1/2, p38, JNK mitogen activated protein kinases MAPK), and cAMP. RESULTS: OM-85 significantly reduced Rhinovirus-induced BEC death and virus replication. OM-85 significantly increased the expression of virus interacting proteins C1q-R and beta-defensin in all 3 probes and groups, which was prevented by either Erk1/2 MAPK or cAMP inhibition. In addition, OM-85 significantly reduced Rhinovirus induced expression of ICAM1 involving p38 MAPK. In BEC OM-85 had no significant effect on the expression of ICOS, ICOSL and MHC-2 membrane proteins nor on the adaptor protein MyD88. CONCLUSION: The OM-85-induced increased of C1q-R and beta-defensin, both important for antigen presentation and phagocytosis, supports its activity in host cell's defence against Rhinovirus infection. PMID- 29182621 TI - Exploring the reproducibility of functional connectivity alterations in Parkinson's disease. AB - Since anatomic MRI is presently not able to directly discern neuronal loss in Parkinson's Disease (PD), studying the associated functional connectivity (FC) changes seems a promising approach toward developing non-invasive and non radioactive neuroimaging markers for this disease. While several groups have reported such FC changes in PD, there are also significant discrepancies between studies. Investigating the reproducibility of PD-related FC changes on independent datasets is therefore of crucial importance. We acquired resting state fMRI scans for 43 subjects (27 patients and 16 normal controls, with 2 replicate scans per subject) and compared the observed FC changes with those obtained in two independent datasets, one made available by the PPMI consortium (91 patients, 18 controls) and a second one by the group of Tao Wu (20 patients, 20 controls). Unfortunately, PD-related functional connectivity changes turned out to be non-reproducible across datasets. This could be due to disease heterogeneity, but also to technical differences. To distinguish between the two, we devised a method to directly check for disease heterogeneity using random splits of a single dataset. Since we still observe non-reproducibility in a large fraction of random splits of the same dataset, we conclude that functional heterogeneity may be a dominating factor behind the lack of reproducibility of FC alterations in different rs-fMRI studies of PD. While global PD-related functional connectivity changes were non-reproducible across datasets, we identified a few individual brain region pairs with marginally consistent FC changes across all three datasets. However, training classifiers on each one of the three datasets to discriminate PD scans from controls produced only low accuracies on the remaining two test datasets. Moreover, classifiers trained and tested on random splits of the same dataset (which are technically homogeneous) also had low test accuracies, directly substantiating disease heterogeneity. PMID- 29182622 TI - Cisplatin or LA-12 enhance killing effects of TRAIL in prostate cancer cells through Bid-dependent stimulation of mitochondrial apoptotic pathway but not caspase-10. AB - Searching for new strategies for effective elimination of human prostate cancer cells, we investigated the cooperative cytotoxic action of tumor necrosis factor related apoptosis-inducing ligand (TRAIL) and two platinum-based complexes, cisplatin or LA-12, and related molecular mechanisms. We demonstrated a notable ability of cisplatin or LA-12 to enhance the sensitivity of several human prostate cancer cell lines to TRAIL-induced cell death via an engagement of mitochondrial apoptotic pathway. This was accompanied by augmented Bid cleavage, Bak activation, loss of mitochondrial membrane potential, activation of caspase 8, -10, -9, and -3, and XIAP cleavage. RNAi-mediated silencing of Bid or Bak in Bax-deficient DU 145 cells suppressed the drug combination-induced cytotoxicity, further underscoring the involvement of mitochondrial signaling. The caspase-10 was dispensable for enhancement of cisplatin/LA-12 and TRAIL combination-induced cell death and stimulation of Bid cleavage. Importantly, we newly demonstrated LA 12-mediated enhancement of TRAIL-induced cell death in cancer cells derived from human patient prostate tumor specimens. Our results provide convincing evidence that employing TRAIL combined with cisplatin/LA-12 could contribute to more effective killing of prostate cancer cells compared to the individual action of the drugs, and offer new mechanistic insights into their cooperative anticancer action. PMID- 29182624 TI - Maternal aging affects oocyte resilience to carbonyl cyanide-m chlorophenylhydrazone -induced mitochondrial dysfunction in cows. AB - Mitochondrial quality control is important for maintaining cellular and oocyte viability. In addition, aging affects mitochondrial quality in many cell types. In the present study, we examined how aging affects oocyte mitochondrial biogenesis and degeneration in response to induced mitochondrial dysfunction. Cumulus oocyte complexes were harvested from the ovaries of young (21-45 months) and aged (>=120 months) cows and treated for 2 hours with 10 MUM carbonyl cyanide m- chlorophenylhydrazone (CCCP), or a vehicle control, after which cumulus oocyte complexes were subjected to in vitro fertilization and culture. CCCP treatment reduced ATP content and increased reactive oxygen species (ROS) levels in the oocytes of both young and aged cows. When CCCP-treated cumulus oocyte complexes were subsequently cultured for 19 hours and/or subjected to fertilization, high ROS levels in oocytes and a low rate of blastocyst development was observed in oocytes derived from aged cows. In addition, we observed differential responses in mitochondrial biogenesis to CCCP treatment between young and aged cows. CCCP treatment enhanced mitochondrial biogenesis concomitant with upregulation of SIRT1 expression in oocytes of young, but not aged, cows. In conclusion, aging affects mitochondrial quality control and recuperation of oocytes following CCCP induced mitochondrial dysfunction. PMID- 29182623 TI - Immunotherapeutic efficacy of liposome-encapsulated refined allergen vaccines against Dermatophagoides pteronyssinus allergy. AB - Allergen specific immunotherapy (AIT) can modulate the allergic response causing a long-term symptom subsidence/abolishment which leads to reduced drug use and prevention of new sensitization. AIT of house dust mite allergy (HDM) using the mite crude extract (CE) as the therapeutic agent is not only less effective than the AIT for many other allergens, but also frequently causes adverse effects during the treatment course. In this study, mouse model of Dermatophagoides pteronyssinus (Dp) allergy was invented for testing therapeutic efficacies of intranasally administered liposome (L) encapsulated vaccines made of single Dp major allergens (L-Der p 1, L-Der p 2), combined allergens (L-Der p 1 and Der p 2), and crude Dp extract (L-CE). The allergen sparing intranasal route was chosen as it is known that the effective cells induced at the nasal-associated lymphoid tissue can exert their activities at the lower respiratory tissue due to the common mucosal traffic. Liposome was chosen as the vaccine delivery vehicle and adjuvant as the micelles could reduce toxicity of the entrapped cargo. The Dp-CE allergic mice received eight doses of individual vaccines/placebo on alternate days. All vaccine formulations caused reduction of the Th2 response of the Dp allergic mice. However, only the vaccines made of single refined allergens induced expressions of immunosuppressive cytokines (TGF-beta, IL-35 and/or IL-10) which are the imperative signatures of successful AIT. The data emphasize the superior therapeutic efficacy of single refined major allergen vaccines than the crude allergenic extract vaccine.

AB - Traumatic brain injury (TBI) is caused by a sudden external force and can be very heterogeneous in its manifestation. In this work, we analyse T1-weighted magnetic resonance (MR) brain images that were prospectively acquired from patients who sustained mild to severe TBI. We investigate the potential of a recently proposed automatic segmentation method to support the outcome prediction of TBI. Specifically, we extract meaningful cross-sectional and longitudinal measurements from acute- and chronic-phase MR images. We calculate regional volume and asymmetry features at the acute/subacute stage of the injury (median: 19 days after injury), to predict the disability outcome of 67 patients at the chronic disease stage (median: 229 days after injury). Our results indicate that small structural volumes in the acute stage (e.g. of the hippocampus, accumbens, amygdala) can be strong predictors for unfavourable disease outcome. Further, group differences in atrophy are investigated. We find that patients with unfavourable outcome show increased atrophy. Among patients with severe disability outcome we observed a significantly higher mean reduction of cerebral white matter (3.1%) as compared to patients with low disability outcome (0.7%).

AB - Lipid nanoparticles (LNPs) or liposomes are the most widely used drug carriers for nanomedicines. The size of LNPs is one of the essential factors affecting drug delivery efficiency and therapeutic efficiency. Here, we demonstrated the effect of lipid concentration and mixing performance on the LNP size using microfluidic devices with the aim of understanding the LNP formation mechanism and controlling the LNP size precisely. We fabricated microfluidic devices with different depths, 11 MUm and 31 MUm, of their chaotic micromixer structures. According to the LNP formation behavior results, by using a low concentration of the lipid solution and the microfluidic device equipped with the 31 MUm chaotic mixer structures, we were able to produce the smallest-sized LNPs yet with a narrow particle size distribution. We also evaluated the mixing rate of the microfluidic devices using a laser scanning confocal microscopy and we estimated the critical ethanol concentration for controlling the LNP size. The critical ethanol concentration range was estimated to be 60-80% ethanol. Ten nanometer sized tuning of LNPs was achieved for the optimum residence time at the critical concentration using the microfluidic devices with chaotic mixer structures. The residence times at the critical concentration necessary to control the LNP size were 10, 15-25, and 50 ms time-scales for 30, 40, and 50 nm-sized LNPs, respectively. Finally, we proposed the LNP formation mechanism based on the determined LNP formation behavior and the critical ethanol concentration. The precise size-controlled LNPs produced by the microfluidic devices are expected to become carriers for next generation nanomedicines and they will lead to new and effective approaches for cancer treatment.

AB - Circulating HPV DNA has been previously described in women with advanced stages of cervical cancer and has been suggested to be a prognostic marker of disease recurrences and metastases. Only a few studies have reported the presence of HPV DNA in bloodstream of patients with low grade or precancerous cervical lesions. This study aimed to define if HPV DNA could be detected in plasma samples of 120 women referred for a recent history of cervical dysplasia who presented with lesions ranging from High Squamous Intraepithelial Lesion (H-SIL) to regressed normal cytology. HPV DNA detection was carried out in both plasma and cervical samples using type-specific real-time quantitative PCR assays identifying oncogenic HPV 16, 18, 31, 33, 45, 51 and 52. Overall, 34.2% (41/120) of plasma samples were shown to be positive for HPV DNA detection; HPV 45 (46.3%), HPV-51 (29.6%), and HPV 16 (18.5%) were the most frequently identified genotypes. The rate of HPV detection in paired cervical and plasma samples increased with advancing disease stage, ranging from 15.4% in women with regressed lesions to 38.9% in women with HSIL; HPV 16 resulted the most common genotype identified in women found to be HPV DNA positive in both cervical and plasma samples. Moreover, HPV 16 showed the highest median viral load value in both cervical and plasma samples, with 48,313 copies/104 cells and 1,099 copies/ml, respectively. Results obtained in this study confirm that HPV DNA can be detected and quantified in plasma samples of women with asymptomatic cervical infection. Further knowledge on HPV dissemination through the blood stream of women with cervical lesions would be very important in better understanding the natural history of HPV infection as well as its potential role in other distant tumors.

AB - Berries are a rich source of antioxidants and phytochemicals that have received considerable interest for their possible relations to human health. In this study, the anti-adipogenic effect of polyphenol-rich extract obtained from chokeberry Aronia melanocarpa (Michx.) Elliot, raspberry Rubus idaeus L., bilberry Vaccinium myrtillus L. and cranberry Vaccinium macrocarpon Aiton fruits and its underlying molecular mechanisms were investigated in differentiated 3T3 L1 adipose cells. Treatment with the extract (25-100 MUg/mL) significantly decreased lipid accumulation and reactive oxygen species generation in adipocytes without showing cytotoxicity. Real-time PCR analysis revealed that the extract at a concentration of 100 MUg/mL suppressed adipogenesis and lipogenesis via the down-regulation of PPARgamma (67%), C/EBPalpha (72%), SREBP1 (62%), aP2 (24%), FAS (32%), LPL (40%), HSL (39%), and PLIN1 (32%) gene expression. Moreover, the extract significantly increased the expression of adiponectin (4.4-fold) and decreased leptin expression (90%) and respectively regulated the production of these adipokines in 3T3-L1 adipocytes. The obtained results suggest that the analyzed extract may be a promising source of bioactive compounds that support long-term weight maintenance and promote the effective management of obesity. PMID- 29182629 TI - Effects of peroxisome proliferator activated receptors (PPAR)-gamma and -alpha agonists on cochlear protection from oxidative stress. AB - Various insults cause ototoxicity in mammals by increasing oxidative stress leading to apoptosis of auditory hair cells (HCs). The thiazolidinediones (TZDs; e.g., pioglitazone) and fibrate (e.g., fenofibrate) drugs are used for the treatment of diabetes and dyslipidemia. These agents target the peroxisome proliferator-activated receptors, PPARgamma and PPARalpha, which are transcription factors that influence glucose and lipid metabolism, inflammation, and organ protection. In this study, we explored the effects of pioglitazone and other PPAR agonists to prevent gentamicin-induced oxidative stress and apoptosis in mouse organ of Corti (OC) explants. Western blots showed high levels of PPARgamma and PPARalpha proteins in mouse OC lysates. Immunofluorescence assays indicated that PPARgamma and PPARalpha proteins are present in auditory HCs and other cell types in the mouse cochlea. Gentamicin treatment induced production of reactive oxygen species (ROS), lipid peroxidation, caspase activation, PARP-1 cleavage, and HC apoptosis in cultured OCs. Pioglitazone mediated its anti apoptotic effects by opposing the increase in ROS induced by gentamicin, which inhibited the subsequent formation of 4-hydroxy-2-nonenal (4-HNE) and activation of pro-apoptotic mediators. Pioglitazone mediated its effects by upregulating genes that control ROS production and detoxification pathways leading to restoration of the reduced:oxidized glutathione ratio. Structurally diverse PPAR agonists were protective of HCs. Pioglitazone (PPARgamma-specific), tesaglitazar (PPARgamma/alpha-specific), and fenofibric acid (PPARalpha-specific) all provided >90% protection from gentamicin toxicity by regulation of overlapping subsets of genes controlling ROS detoxification. This study revealed that PPARs play important roles in the cochlea, and that PPAR-targeting drugs possess therapeutic potential as treatment for hearing loss. PMID- 29182630 TI - Connectivity and systemic resilience of the Great Barrier Reef. AB - Australia's iconic Great Barrier Reef (GBR) continues to suffer from repeated impacts of cyclones, coral bleaching, and outbreaks of the coral-eating crown-of thorns starfish (COTS), losing much of its coral cover in the process. This raises the question of the ecosystem's systemic resilience and its ability to rebound after large-scale population loss. Here, we reveal that around 100 reefs of the GBR, or around 3%, have the ideal properties to facilitate recovery of disturbed areas, thereby imparting a level of systemic resilience and aiding its continued recovery. These reefs (1) are highly connected by ocean currents to the wider reef network, (2) have a relatively low risk of exposure to disturbances so that they are likely to provide replenishment when other reefs are depleted, and (3) have an ability to promote recovery of desirable species but are unlikely to either experience or spread COTS outbreaks. The great replenishment potential of these 'robust source reefs', which may supply 47% of the ecosystem in a single dispersal event, emerges from the interaction between oceanographic conditions and geographic location, a process that is likely to be repeated in other reef systems. Such natural resilience of reef systems will become increasingly important as the frequency of disturbances accelerates under climate change.

PMID- 29182632 TI - A comparison of the effects of fire on rodent abundance and diversity in the Great Basin and Mojave Deserts. AB - As invasive grasses and fire increase in frequency and extent in North American deserts, they have the potential to affect animal communities through bottom-up forces. We experimentally tested the effects of fire on rodent communities of the Great Basin and Mojave Deserts. Fire decreased the abundance, richness, and diversity of rodents in the Great Basin after fire. In the Mojave, abundance was unaffected and diversity and species richness were greater on burned than unburned plots 4 months after fire. The effects of fire on rodent communities tended to decrease over time. The differences in effects between the deserts may be due to differences in the foraging preferences of the dominant species at each site. As these species are primarily herbivorous, short-term changes to the rodent community could have long-term implications by affecting the recovery of the plant community after fire. PMID- 29182633 TI - Extensive virologic and immunologic characterization in an HIV-infected individual following allogeneic stem cell transplant and analytic cessation of antiretroviral therapy: A case study. AB - BACKGROUND: Notwithstanding 1 documented case of HIV-1 cure following allogeneic stem cell transplantation (allo-SCT), several subsequent cases of allo-SCT in HIV 1 positive individuals have failed to cure HIV-1 infection. The aim of our study was to describe changes in the HIV reservoir in a single chronically HIV-infected patient on suppressive antiretroviral therapy who underwent allo-SCT for treatment of acute lymphoblastic leukemia. METHODS AND FINDINGS: We prospectively collected peripheral blood mononuclear cells (PBMCs) by leukapheresis from a 55 year-old man with chronic HIV infection before and after allo-SCT to measure the size of the HIV-1 reservoir and characterize viral phylogeny and phenotypic changes in immune cells. At day 784 post-transplant, when HIV-1 was undetectable by multiple measures-including PCR measurements of both total and integrated HIV 1 DNA, replication-competent virus measurement by large cell input quantitative viral outgrowth assay, and in situ hybridization of colon tissue-the patient consented to an analytic treatment interruption (ATI) with frequent clinical monitoring. He remained aviremic off antiretroviral therapy until ATI day 288, when a low-level virus rebound of 60 HIV-1 copies/ml occurred, which increased to 1,640 HIV-1 copies/ml 5 days later, prompting reinitiation of ART. Rebounding plasma HIV-1 sequences were phylogenetically distinct from proviral HIV-1 DNA detected in circulating PBMCs before transplantation. The main limitations of this study are the insensitivity of reservoir measurements, and the fact that it describes a single case. CONCLUSIONS: allo-SCT led to a significant reduction in the size of the HIV-1 reservoir and a >9-month-long ART-free remission from HIV-1 replication. Phylogenetic analyses suggest that the origin of rebound virus was distinct from the viruses identified pre-transplant in the PBMCs. PMID- 29182634 TI - Direct provision versus facility collection of HIV self-tests among female sex workers in Uganda: A cluster-randomized controlled health systems trial. AB - BACKGROUND: HIV self-testing allows HIV testing at any place and time and without health workers. HIV self-testing may thus be particularly useful for female sex workers (FSWs), who should test frequently but face stigma and financial and time barriers when accessing healthcare facilities. METHODS AND FINDINGS: We conducted a cluster-randomized controlled health systems trial among FSWs in Kampala, Uganda, to measure the effect of 2 HIV self-testing delivery models on HIV testing and linkage to care outcomes. FSW peer educator groups (1 peer educator and 8 participants) were randomized to either (1) direct provision of HIV self tests, (2) provision of coupons for free collection of HIV self-tests in a healthcare facility, or (3) standard of care HIV testing. We randomized 960 participants in 120 peer educator groups from October 18, 2016, to November 16, 2016. Participants' median age was 28 years (IQR 24-32). Our prespecified primary outcomes were self-report of any HIV testing at 1 month and at 4 months; our prespecified secondary outcomes were self-report of HIV self-test use, seeking HIV-related medical care and ART initiation. In addition, we analyzed 2 secondary outcomes that were not prespecified: self-report of repeat HIV testing-to understand the intervention effects on frequent testing-and self-reported facility-based testing-to quantify substitution effects. Participants in the direct provision arm were significantly more likely to have tested for HIV than those in the standard of care arm, both at 1 month (risk ratio [RR] 1.33, 95% CI 1.17-1.51, p < 0.001) and at 4 months (RR 1.14, 95% CI 1.07-1.22, p < 0.001). Participants in the direct provision arm were also significantly more likely to have tested for HIV than those in the facility collection arm, both at 1 month (RR 1.18, 95% CI 1.07-1.31, p = 0.001) and at 4 months (RR 1.03, 95% CI 1.01 1.05, p = 0.02). At 1 month, fewer participants in the intervention arms had sought medical care for HIV than in the standard of care arm, but these differences were not significant and were reduced in magnitude at 4 months. There were no statistically significant differences in ART initiation across study arms. At 4 months, participants in the direct provision arm were significantly more likely to have tested twice for HIV than those in the standard of care arm (RR 1.51, 95% CI 1.29-1.77, p < 0.001) and those in the facility collection arm (RR 1.22, 95% CI 1.08-1.37, p = 0.001). Participants in the HIV self-testing arms almost completely replaced facility-based testing with self-testing. Two adverse events related to HIV self-testing were reported: interpersonal violence and mental distress. Study limitations included self-reported outcomes and limited generalizability beyond FSWs in similar settings. CONCLUSIONS: In this study, HIV self-testing appeared to be safe and increased recent and repeat HIV testing among FSWs. We found that direct provision of HIV self-tests was significantly more effective in increasing HIV testing among FSWs than passively offering HIV self-tests for collection in healthcare facilities. HIV self-testing could play an important role in supporting HIV interventions that require frequent HIV testing, such as HIV treatment as prevention, behavior change for transmission reduction, and pre-exposure prophylaxis. TRIAL REGISTRATION: ClinicalTrials.gov NCT02846402. PMID- 29182635 TI - The evolution and adaptation of A-to-I RNA editing. AB - Adenosine-to-inosine (A-to-I) RNA editing is an important post-transcriptional modification that affects the information encoded from DNA to RNA to protein. RNA editing can generate a multitude of transcript isoforms and can potentially be used to optimize protein function in response to varying conditions. In light of this and the fact that millions of editing sites have been identified in many different species, it is interesting to examine the extent to which these sites have evolved to be functionally important. In this review, we discuss results pertaining to the evolution of RNA editing, specifically in humans, cephalopods, and Drosophila. We focus on how comparative genomics approaches have aided in the identification of sites that are likely to be advantageous. The use of RNA editing as a mechanism to adapt to varying environmental conditions will also be reviewed. PMID- 29182636 TI - Identification of differences in health impact modelling of salt reduction. AB - We examined whether specific input data and assumptions explain outcome differences in otherwise comparable health impact assessment models. Seven population health models estimating the impact of salt reduction on morbidity and mortality in western populations were compared on four sets of key features, their underlying assumptions and input data. Next, assumptions and input data were varied one by one in a default approach (the DYNAMO-HIA model) to examine how it influences the estimated health impact. Major differences in outcome were related to the size and shape of the dose-response relation between salt and blood pressure and blood pressure and disease. Modifying the effect sizes in the salt to health association resulted in the largest change in health impact estimates (33% lower), whereas other changes had less influence. Differences in health impact assessment model structure and input data may affect the health impact estimate. Therefore, clearly defined assumptions and transparent reporting for different models is crucial. However, the estimated impact of salt reduction was substantial in all of the models used, emphasizing the need for public health actions. PMID- 29182637 TI - Local ecological knowledge and its relationship with biodiversity conservation among two Quilombola groups living in the Atlantic Rainforest, Brazil. AB - Information on the knowledge, uses, and abundance of natural resources in local communities can provide insight on conservation status and conservation strategies in these locations. The aim of this research was to evaluate the uses, knowledge and conservation status of plants in two Quilombolas (descendants of slaves of African origin) communities in the Atlantic rainforest of Brazil, Sao Sebastiao da Boa Vista (SSBV) and Sao Bento (SB). We used a combination of ethnobotanical and ecological survey methods to ask: 1) What ethnobotanical knowledge do the communities hold? 2) What native species are most valuable to them? 3) What is the conservation status of the native species used? Thirteen local experts described the names and uses of 212 species in SSBV (105 native species) and 221 in SB (96 native species). Shannon Wiener diversity and Pielou's Equitability indices of ethnobotanical knowledge of species were very high (5.27/0.96 and 5.28/0.96, respectively). Species with the highest cultural significance and use-value indexes in SSBV were Dalbergia hortensis (26/2.14), Eremanthus erythropappus (6.88/1), and Tibouchina granulosa (6.02/1); while Piptadenia gonoacantha (3.32/1), Sparattosperma leucanthum (3.32/1) and Cecropia glaziovii (3.32/0.67) were the highest in SB. Thirty-three native species ranked in the highest conservation priority category at SSBV and 31 at SB. D. hortensis was noteworthy because of its extremely high cultural importance at SSBV, and its categorization as a conservation priority in both communities. This information can be used towards generating sustainable use and conservation plans that are appropriate for the local communities. PMID- 29182638 TI - Respondent-driven sampling for identification of HIV- and HCV-infected people who inject drugs and men who have sex with men in India: A cross-sectional, community based analysis. AB - BACKGROUND: A major barrier to achieving ambitious targets for global control of HIV and hepatitis C virus (HCV) is low levels of awareness of infection among key populations such as men who have sex with men (MSM) and people who inject drugs (PWID). We explored the potential of a strategy routinely used for surveillance in these groups, respondent-driven sampling (RDS), to be used as an intervention to identify HIV- and HCV-infected PWID and MSM who are unaware of their status and those who are viremic across 26 Indian cities at various epidemic stages. METHODS AND FINDINGS: Data were collected as part of the baseline assessment of an ongoing cluster-randomized trial. RDS was used to accrue participants at 27 sites (15 PWID sites and 12 MSM sites) selected to reflect varying stages of the HIV epidemic among MSM and PWID in India. A total of 56 seeds recruited a sample of 26,447 persons (approximately 1,000 participants per site) between October 1, 2012, and December 19, 2013. Across MSM sites (n = 11,997), the median age was 25 years and the median number of lifetime male partners was 8. Across PWID sites (n = 14,450), 92.4% were male, the median age was 30 years, and 87.5% reported injection in the prior 6 months. RDS identified 4,051 HIV-infected persons, of whom 2,325 (57.4%) were unaware of their HIV infection and 2,816 (69.5%) were HIV viremic. It also identified 5,777 HCV-infected persons, of whom 5,337 (92.4%) were unaware that they were infected with HCV and 4,728 (81.8%) were viremic. In the overall sample (both MSM and PWID), the prevalence of HIV-infected persons who were unaware of their status increased with sampling depth, from 7.9% in participants recruited in waves 1 through 5 to 12.8% among those recruited in waves 26 and above (p-value for trend < 0.001). The overall detection rate of people unaware of their HIV infection was 0.5 persons per day, and the detection rate of HIV-infected persons with viremia (regardless of their awareness status) was 0.7 per day. The detection rate of HIV viremic individuals was positively associated with underlying HIV prevalence and the prevalence of HIV viremia (linear regression coefficient per 1-percentage-point increase in prevalence: 0.05 and 0.07, respectively). The median detection rate of PWID who were unaware of their HCV infection was 2.5 per day. The cost of identifying 1 unaware HIV infected individual ranged from US$51 to US$2,072 across PWID sites and from US$189 to US$5,367 across MSM sites. The mean additional cost of identifying 1 unaware HCV-infected PWID was US$13 (site range: US$7-US$140). Limitations of the study include the exclusivity of study sites to India, lack of prior HIV/HCV diagnosis confirmation with clinic records, and lack of cost data from other case finding approaches commonly used in India. CONCLUSIONS: In this study, RDS was able to rapidly identify at nominal cost a substantial number of unaware and viremic HIV-infected and HCV-infected individuals who were currently not being reached by existing programs and who were at high risk for transmission. Combining RDS (or other network-driven recruitment approaches) with strategies focused on linkage to care, particularly in high-burden settings, may be a viable option for achieving the 90-90-90 targets in key populations in resource-limited settings. PMID- 29182639 TI - Mycophenolate mofetil prevents the delayed T cell response after pilocarpine induced status epilepticus in mice. AB - Growing clinical and laboratory evidence corroborates a role for the immune system in the pathophysiology of epilepsy. In order to delineate the immune response following pilocarpine-induced status epilepticus (SE) in the mouse, we monitored the kinetics of leukocyte presence in the hippocampus over the period of four weeks. SE was induced following a ramping protocol of pilocarpine injection into 4-5 weeks old C57BL/6 mice. Brains were removed at days 1-4, 14 or 28 after SE, and the hippocampi were analyzed via flow cytometry, via quantitative reverse transcriptase PCR (qRT-PCR) and via immunohistochemistry. Epileptogenesis was confirmed by Timm staining of mossy fiber sprouting in the inner molecular layer of the dentate gyrus. The flow cytometry data revealed a biphasic immune response following pilocarpine-induced SE with a transient increase in activated CD11b+ and F4/80+ macrophages within the first four days replaced by an increase in CD3+ T-lymphocytes around day 28. This delayed T cell response was confirmed via qRT-PCR and via immunohistochemistry. In addition, qRT PCR data could show that the delayed T cell response was associated with an increased CD8/CD4 ratio indicating a cytotoxic T cell response after SE. Intriguingly, early intervention with mycophenolate mofetil administration on days 0-3 after SE prevented this delayed T cell response. These results show an orchestrated immunological sequela and provide evidence that the delayed T cell response is sensitive to early immunomodulatory intervention. PMID- 29182640 TI - Changes in the interstitial cells of Cajal and neuronal nitric oxide synthase positive neuronal cells with aging in the esophagus of F344 rats. AB - The aging-associated cellular and molecular changes in esophagus have not been established, yet. Thus we evaluated histological structure, interstitial cells of Cajal (ICCs), neuronal nitric oxide synthase (nNOS)-positive cells, and contractility in the esophagus of Fischer 344 rat at different ages (6-, 31-, 74 weeks, and 2-years). The lamina propria thickness and endomysial area were calculated. The immunoreactivity of c-Kit, nNOS and protein gene product (PGP) 9.5 was counted after immunohistochemistry. Expression of c-Kit, stem cell factor (SCF), nNOS and PGP 9.5 mRNA was measured by real-time PCR, and expression of c Kit and nNOS protein was detected by Western blot. Isovolumetric contractile force measurement and electrical field stimulation (EFS) were conducted. The lamina propria thickness increased (6 week vs 2 year, P = 0.005) and the endomysial area of longitudinal muscle decreased with aging (6 week vs 2 year, P<0.001), while endomysial area of circular muscle did not significantly decrease. The proportions of NOS-immunoreactive cells and c-Kit-immunoreactive areas declined with aging (6 week vs 2 year; P<0.001 and P = 0.004, respectively), but there was no significant change of PGP 9.5-immunopositiviy. The expressions of nNOS, c-Kit and SCF mRNA also reduced with aging (6 week vs 2 year; P = 0.006, P = 0.001 and P = 0.006, respectively), while the change of PGP 9.5 mRNA expression was not significant. Western blot showed the significant decreases of nNOS and c-Kit protein expression with aging (6 week vs 2 year; P = 0.008 and P = 0.012, respectively). The EFS-induced esophageal contractions significantly decreased in 2-yr-old rat compared with 6-wk-old rats, however, L NG-Nitroarginine methylester did not significantly increase the spontaneous and EFS-induced contractions in the 6-wk- and 2-yr-old rat esophagus. In conclusion, an increase of lamina propria thickness, a decrease of endomysial area, c-Kit, SCF and NOS expression with preserved total enteric neurons, and contractility in aged rat esophagus may explain the aging-associated esophageal dysmotility. PMID- 29182641 TI - Treatment eligibility and retention in clinical HIV care: A regression discontinuity study in South Africa. AB - BACKGROUND: Loss to follow-up is high among HIV patients not yet receiving antiretroviral therapy (ART). Clinical trials have demonstrated the clinical efficacy of early ART; however, these trials may miss an important real-world consequence of providing ART at diagnosis: its impact on retention in care. METHODS AND FINDINGS: We examined the effect of immediate (versus deferred) ART on retention in care using a regression discontinuity design. The analysis included all patients (N = 11,306) entering clinical HIV care with a first CD4 count between 12 August 2011 and 31 December 2012 in a public-sector HIV care and treatment program in rural South Africa. Patients were assigned to immediate versus deferred ART eligibility, as determined by a CD4 count < 350 cells/MUl, per South African national guidelines. Patients referred to pre-ART care were instructed to return every 6 months for CD4 monitoring. Patients initiated on ART were instructed to return at 6 and 12 months post-initiation and annually thereafter for CD4 and viral load monitoring. We assessed retention in HIV care at 12 months, as measured by the presence of a clinic visit, lab test, or ART initiation 6 to 18 months after initial CD4 test. Differences in retention between patients presenting with CD4 counts just above versus just below the 350 cells/MUl threshold were estimated using local linear regression models with a data-driven bandwidth and with the algorithm for selecting the bandwidth chosen ex ante. Among patients with CD4 counts close to the 350-cells/MUl threshold, having an ART-eligible CD4 count (<350 cells/MUl) was associated with higher 12 month retention than not having an ART-eligible CD4 count (50% versus 32%), an intention-to-treat risk difference of 18 percentage points (95% CI 11 to 23; p < 0.001). The decision to start ART was determined by CD4 count for one in four patients (25%) presenting close to the eligibility threshold (95% CI 20% to 31%; p < 0.001). In this subpopulation, having an ART-eligible CD4 count was associated with higher 12-month retention than not having an ART-eligible CD4 count (91% versus 21%), a complier causal risk difference of 70 percentage points (95% CI 42 to 98; p < 0.001). The major limitations of the study are the potential for limited generalizability, the potential for outcome misclassification, and the absence of data on longer-term health outcomes. CONCLUSIONS: Patients who were eligible for immediate ART had dramatically higher retention in HIV care than patients who just missed the CD4-count eligibility cutoff. The clinical and population health benefits of offering immediate ART regardless of CD4 count may be larger than suggested by clinical trials. PMID- 29182642 TI - Elevated N-telopeptide as a potential diagnostic marker for bone metastasis in lung cancer: A meta-analysis. AB - BACKGROUND: Growing evidence indicates that the cross-linked N-telopeptide of type I collagen (NTx) is likely to be involved in the development of bone metastasis among lung cancer patients. We perform a meta-analysis to disclose the correlation between bone metastasis and NTx and also to evaluate its value in diagnosis of bone metastasis (BM) in lung cancer. METHOD: Electronic databases were searched and calculated the weighted mean difference (WMD) with 95% confidence interval (CI) to assess the expression difference of NTx between BM+ and BM- lung cancer patients. Moreover, we conducted a sensitivity and specificity test and drew a summary receiver operating characteristic curve (SROC) to assess the diagnostic value of NTx in discerning bone metastasis. RESULTS: A total of eleven studies with 1108 individuals were included in this analysis. The results showed an increased NTx was correlated with the incidence of lung cancer (P < 0.001). The overall sensitivity and specificity of serum NTx (sNTx) for discerning bone metastasis was 0.74 (95% CI = 0.67 to 0.79) and 0.85 (95% CI = 0.80 to 0.89), respectively. As for urine NTx (uNTx) the pooled sensitivity and specificity was 0.77(95% CI = 0.67 to 0.86) and 0.81(95% CI = 0.76 to 0.86). The area under the SROC curve was 0.8889(SE = 0.0255) and 0.8655(SE = 0.0254) for sNTx and uNTx respectively. CONCLUSIONS: The elevation of NTx in lung cancer was positively related with the development and progression of bone metastasis. A higher specificity over sensitivity of NTx suggested that it is a more accurate biomarker to distinguish patients without bone metastasis. Regarding SROC curve, sNTx may be a better choice. PMID- 29182643 TI - How do adults and teens with self-declared Autism Spectrum Disorder experience eye contact? A qualitative analysis of first-hand accounts. AB - A tendency to avoid eye contact is an early indicator of Autism Spectrum Disorder (ASD), and difficulties with eye contact often persist throughout the lifespan. Eye contact difficulties may underlie social cognitive deficits in ASD, and can create significant social and occupational barriers. Thus, this topic has received substantial research and clinical attention. In this study, we used qualitative methods to analyze self-reported experiences with eye contact as described by teens and adults with self-declared ASD. Results suggest people with a self- declared ASD diagnosis experience adverse emotional and physiological reactions, feelings of being invaded, and sensory overload while making eye contact, in addition to difficulties understanding social nuances, and difficulties receiving and sending nonverbal information. Some data support existing mindblindness frameworks, and hyperarousal or hypoarousal theories of eye contact, but we also present novel findings unaccounted for by existing frameworks. Additionally, we highlight innovative strategies people with self declared ASD have devised to overcome or cope with their eye contact difficulties.

AB - OBJECTIVE: There is increasing concern that mental health may be deteriorating in recent generations of adolescents. It is unclear whether this is the case for self-reported psychosomatic health complaints (PSHC). METHOD: We conducted a systematic review and meta-analysis of published primary studies on PSHC in the general adolescent population over time. The primary databases were MEDLINE, Embase and PsycINFO, which were searched from inception to November 2016. Studies were included if they involved an observational design, presented self-reported data from participants aged 10-19 years and included data from at least two time points, five years apart. Inclusion and study quality were assessed by two independent reviewers. RESULTS: Twenty-one studies were included; 18 reported trends on the prevalence of PSHC in a single country, while three studies reported on multiple countries. In total, over seven million adolescents from 36 countries in Europe, North America, Israel and New Zealand were represented, covering the period 1982-2013. In the descriptive analysis, 10 studies indicated a trend of increasing PSHC, eight showed a stable trend and three showed a decreasing trend at certain points in time. The results from the meta-analysis showed a mean odds ratio (OR) of 1.04 (K = 139, 95% CI 1.01-1.08) for PSHC from 1982 to 2013, thus indicating a minor increase in general. In the subgroup analysis, this minor increase was observed mainly between the 1980s and 2000s, while the trend appeared to be more stable between the 2000s and 2010s. Some differences were also found between multinational subregions. Findings from subgroup analysis, however, only supported a significant increasing trend in Northern Europe. CONCLUSION: There may have been a minor increasing trend in adolescent self-rated PSHC between the 1980 and 2000s, but has become more stable since the 2010s, from a multinational perspective. Northern Europe was the only region to show a clearly significant minor increasing trend, without being the region with the highest total prevalence of PSHC at the present time. The discrepant trends regarding PSHC between regions and the reliance on self reported data may reflect true changes in the occurrence of PSHC in the adolescent population. However, they may also reflect changes in how adolescents perceive and report health complaints. OTHER: PROSPERO registration 2016: CRD42016048300.

AB - Genetic predisposition could be assumed to be causing clustering of autoimmunity in individuals and families. We tested whether HLA and non-HLA loci associate with such clustering of autoimmunity. We included 1,745 children with type 1 diabetes from the Finnish Pediatric Diabetes Register. Data on personal or family history of autoimmune diseases were collected with a structured questionnaire and, for a subset, with a detailed search for celiac disease and autoimmune thyroid disease. Children with multiple autoimmune diseases or with multiple affected first- or second-degree relatives were identified. We analysed type 1 diabetes related HLA class II haplotypes and genotyped 41 single nucleotide polymorphisms (SNPs) outside the HLA region. The HLA-DR4-DQ8 haplotype was associated with having type 1 diabetes only whereas the HLA-DR3-DQ2 haplotype was more common in children with multiple autoimmune diseases. Children with multiple autoimmune diseases showed nominal association with RGS1 (rs2816316), and children coming from an autoimmune family with rs11711054 (CCR3-CCR5). In multivariate analyses, the overall effect of non-HLA SNPs on both phenotypes was evident, associations with RGS1 and CCR3-CCR5 region were confirmed and additional associations were implicated: NRP1, FUT2, and CD69 for children with multiple autoimmune diseases. In conclusion, HLA-DR3-DQ2 haplotype and some non HLA SNPs contribute to the clustering of autoimmune diseases in children with type 1 diabetes and in their families.

AB - Heterotrophic feeding in newly-settled coral planulae can potentially improve survivorship and accelerate early development in some species; however, an optimal diet to facilitate this does not currently exist. This study evaluated the efficacy of three heterotrophic feeding regimes (enriched rotifers, unfiltered seawater, and a novel, particulate diet), against a wholly phototrophic treatment on Acropora hyacinthus, A. loripes, A. millepora, and A. tenuis recruits, over 93 days post-settlement. The unfiltered seawater treatment recorded maximum survival for all species (A. hyacinthus 95.9+/-8.0%, A. loripes: 74.3+/-11.5%, A. millepora: 67+/-12.7%, A. tenuis: 53.2+/-11.3%), although not significant. Growth (% surface area gain) was also greatest in the unfiltered seawater, and this was significant for A. millepora (870+/-307%) and A. tenuis (693+/-91.8%) (p<0.05). Although total lipid concentration was relatively stable across treatments, the lipid class composition exhibited species-specific responses to each treatment. Lower saturated and higher polyunsaturated fatty acids appeared beneficial to recruit performance, particularly in the unfiltered seawater, which generally contained the highest levels of 20:5n-3 (EPA), 22:6n-3 (DHA), and 20:4n-6 (ARA). The present study demonstrates the capacity of a nutritionally adequate and readily accepted heterotrophic feeding regime to increase coral recruit survival, growth, and health, which can greatly reduce the time required in cost- and labour-intensive culture. PMID- 29182646 TI - Transcriptome-wide analysis of the Trypanosoma cruzi proliferative cycle identifies the periodically expressed mRNAs and their multiple levels of control. AB - Trypanosoma cruzi is the protozoan parasite causing American trypanosomiasis or Chagas disease, a neglected parasitosis with important human health impact in Latin America. The efficacy of current therapy is limited, and its toxicity is high. Since parasite proliferation is a fundamental target for rational drug design, we sought to progress into its understanding by applying a genome-wide approach. Treating a TcI linage strain with hydroxyurea, we isolated epimastigotes in late G1, S and G2/M cell cycle stages at 70% purity. The sequencing of each phase identified 305 stage-specific transcripts (1.5-fold change, p<=0.01), coding for conserved cell cycle regulated proteins and numerous proteins whose cell cycle dependence has not been recognized before. Comparisons with the parasite T. brucei and the human host reveal important differences. The meta-analysis of T. cruzi transcriptomic and ribonomic data indicates that cell cycle regulated mRNAs are subject to sub-cellular compartmentalization. Compositional and structural biases of these genes- including CAI, GC content, UTR length, and polycistron position- may contribute to their regulation. To discover nucleotide motifs responsible for the co-regulation of cell cycle regulated genes, we looked for overrepresented motifs at their UTRs and found a variant of the cell cycle sequence motif at the 3' UTR of most of the S and G2 stage genes. We additionally identified hairpin structures at the 5' UTRs of a high proportion of the transcripts, suggesting that periodic gene expression might also rely on translation initiation in T. cruzi. In summary, we report a comprehensive list of T. cruzi cell cycle regulated genes, including many previously unstudied proteins, we show evidence favoring a multi-step control of their expression, and we identify mRNA motifs that may mediate their regulation. Our results provide novel information of the T. cruzi proliferative proteins and the integrated levels of their gene expression control. PMID- 29182648 TI - The neural response properties and cortical organization of a rapidly adapting muscle sensory group response that overlaps with the frequencies that elicit the kinesthetic illusion. AB - Kinesthesia is the sense of limb movement. It is fundamental to efficient motor control, yet its neurophysiological components remain poorly understood. The contributions of primary muscle spindles and cutaneous afferents to the kinesthetic sense have been well studied; however, potential contributions from muscle sensory group responses that are different than the muscle spindles have not been ruled out. Electrophysiological recordings in peripheral nerves and brains of male Sprague Dawley rats with a degloved forelimb preparation provide evidence of a rapidly adapting muscle sensory group response that overlaps with vibratory inputs known to generate illusionary perceptions of limb movement in humans (kinesthetic illusion). This group was characteristically distinct from type Ia muscle spindle fibers, the receptor historically attributed to limb movement sensation, suggesting that type Ia muscle spindle fibers may not be the sole carrier of kinesthetic information. The sensory-neural structure of muscles is complex and there are a number of possible sources for this response group; with Golgi tendon organs being the most likely candidate. The rapidly adapting muscle sensory group response projected to proprioceptive brain regions, the rodent homolog of cortical area 3a and the second somatosensory area (S2), with similar adaption and frequency response profiles between the brain and peripheral nerves. Their representational organization was muscle-specific (myocentric) and magnified for proximal and multi-articulate limb joints. Projection to proprioceptive brain areas, myocentric representational magnification of muscles prone to movement error, overlap with illusionary vibrational input, and resonant frequencies of volitional motor unit contraction suggest that this group response may be involved with limb movement processing. PMID- 29182650 TI - Predictors of adherence to a new erythropoiesis-stimulating agent inpatient ordering policy: A cross-sectional study. AB - BACKGROUND: Erythropoiesis-stimulating agents (ESAs) are recommended for treating anemia in patients with chronic kidney disease and end-stage renal disease. However, misappropriate and over-use of these agents can be costly and unnecessary in some settings. OBJECTIVE: The primary aim was to identify predictors of adherence to a newly approved ESA inpatient ordering policy. The secondary aims were to evaluate the impact of a 5-day delay in the initiation of ESA therapy on ESA usage, hemoglobin (Hb) levels, and costs. METHODS: This retrospective observational record review included a sample of adult patients admitted to four tertiary care hospitals from November 1, 2013 to August 31, 2014. Multivariable logistic and linear regression analyses were used to calculate the odds of adherence to the new ESA inpatient ordering policy and the impact of this policy on discharge Hb level, respectively. RESULTS: A total of 242 patients were included. The majority of the prescribers (77%) adhered to the new ESA ordering policy. Hemoglobin (OR = 1.306; 95% CI: 1.03-1.65) and ferritin (OR = 3.91; 95% CI: 1.23-12.51) levels at admission and length of hospital stay were positively correlated with the odds of patients receiving ESAs after day 5 (OR = 1.12; 95% CI:1.05-1.20). Furthermore, adherence to the new policy did not have a significant impact on discharge Hb level (beta = 0.02349; P = 0.895). CONCLUSIONS: Prescribers were adherent to a 5-day delay in the initiation of ESA therapy policy which resulted in a reduction in ESA usage, did not impact the discharge Hb levels, and was proven to be cost effective. PMID- 29182649 TI - Men's perspectives of prostate cancer screening: A systematic review of qualitative studies. AB - BACKGROUND: Prostate cancer is the most commonly diagnosed non-skin cancer in men. Screening for prostate cancer is widely accepted; however concerns regarding the harms outweighing the benefits of screening exist. Although patient's play a pivotal role in the decision making process, men may not be aware of the controversies regarding prostate cancer screening. Therefore we aimed to describe men's attitudes, beliefs and experiences of prostate cancer screening. METHODS: Systematic review and thematic synthesis of qualitative studies on men's perspectives of prostate cancer screening. Electronic databases and reference lists were searched to October 2016. FINDINGS: Sixty studies involving 3,029 men aged from 18-89 years, who had been screened for prostate cancer by Prostate Specific Antigen (PSA) or Digital Rectal Examination (DRE) and not screened, across eight countries were included. Five themes were identified: Social prompting (trusting professional opinion, motivation from family and friends, proximity and prominence of cancer); gaining decisional confidence (overcoming fears, survival imperative, peace of mind, mental preparation, prioritising wellbeing); preserving masculinity (bodily invasion, losing sexuality, threatening manhood, medical avoidance); avoiding the unknown and uncertainties (taboo of cancer-related death, lacking tangible cause, physiological and symptomatic obscurity, ambiguity of the procedure, confusing controversies); and prohibitive costs. CONCLUSIONS: Men are willing to participate in prostate cancer screening to prevent cancer and gain reassurance about their health, particularly when supported or prompted by their social networks or healthcare providers. However, to do so they needed to mentally overcome fears of losing their masculinity and accept the intrusiveness of screening, the ambiguities about the necessity and the potential for substantial costs. Addressing the concerns and priorities of men may facilitate informed decisions about prostate cancer screening and improve patient satisfaction and outcomes. PMID- 29182651 TI - Evidence of increased toxic Alexandrium tamarense dinoflagellate blooms in the eastern Bering Sea in the summers of 2004 and 2005. AB - The eastern Bering Sea has a vast continental shelf, which contains various endangered marine mammals and large fishery resources. Recently, high numbers of toxic A. tamarense resting cysts were found in the bottom sediment surface of the eastern Bering Sea shelf, suggesting that the blooms have recently occurred. However, little is known about the presence of A. tamarense vegetative cells in the eastern Bering Sea. This study's goals were to detect the occurrence of A. tamarense vegetative cells on the eastern Bering Sea shelf and to find a relationship between environmental factors and their presence. Inter-annual field surveys were conducted to detect A. tamarense cells and environmental factors, such as nutrients, salinity, chlorophyll a, and water temperature, along a transect line on the eastern Bering Sea shelf during the summers of 2004, 2005, 2006, 2009, 2012, and 2013. A. tamarense vegetative cells were detected during every sampling year, and their quantities varied greatly from year to year. The maximum cell densities of A. tamarense observed during the summers of 2004 and 2005 were much higher than the Paralytic shellfish poisoning warning levels, which are greater than 100-1,000 cells L-1, in other subarctic areas. Lower quantities of the species occurred during the summers of 2009, 2012, and 2013. A significant positive correlation between A. tamarense quantity and water temperature and significant negative correlations between A. tamarense quantity and nutrient concentrations (of phosphate, silicate, and nitrite and nitrate) were detected in every sampling period. The surface- and bottom-water temperatures varied significantly from year to year, suggesting that water temperatures, which have been known to affect the cell growth and cyst germination of A. tamarense, might have affected the cells' quantities in the eastern Bering Sea each summer. Thus, an increase in the Bering Sea shelf's water temperature during the summer will increase the frequency and scale of toxic blooms and the toxin contamination of plankton feeders. This poses serious threats to humans and the marine ecosystem. PMID- 29182652 TI - Primary care and health inequality: Difference-in-difference study comparing England and Ontario. AB - BACKGROUND: It is not known whether equity-oriented primary care investment that seeks to scale up the delivery of effective care in disadvantaged communities can reduce health inequality within high-income settings that have pre-existing universal primary care systems. We provide some non-randomised controlled evidence by comparing health inequality trends between two similar jurisdictions one of which implemented equity-oriented primary care investment in the mid-to late 2000s as part of a cross-government strategy for reducing health inequality (England), and one which invested in primary care without any explicit equity objective (Ontario, Canada). METHODS: We analysed whole-population data on 32,482 neighbourhoods (with mean population size of approximately 1,500 people) in England, and 18,961 neighbourhoods (with mean population size of approximately 700 people) in Ontario. We examined trends in mortality amenable to healthcare by decile groups of neighbourhood deprivation within each jurisdiction. We used linear models to estimate absolute and relative gaps in amenable mortality between most and least deprived groups, considering the gradient between these extremes, and evaluated difference-in-difference comparisons between the two jurisdictions. RESULTS: Inequality trends were comparable in both jurisdictions from 2004-6 but diverged from 2007-11. Compared with Ontario, the absolute gap in amenable mortality in England fell between 2004-6 and 2007-11 by 19.8 per 100,000 population (95% CI: 4.8 to 34.9); and the relative gap in amenable mortality fell by 10 percentage points (95% CI: 1 to 19). The biggest divergence occurred in the most deprived decile group of neighbourhoods. DISCUSSION: In comparison to Ontario, England succeeded in reducing absolute socioeconomic gaps in mortality amenable to healthcare from 2007 to 2011, and preventing them from growing in relative terms. Equity-oriented primary care reform in England in the mid-to-late 2000s may have helped to reduce socioeconomic inequality in health, though other explanations for this divergence are possible and further research is needed on the specific causal mechanisms. PMID- 29182653 TI - Recovery from trauma induced amnesia correlates with normalization of thrombin activity in the mouse hippocampus. AB - Transient amnesia is a common consequence of minimal traumatic brain injury (mTBI). However, while recent findings have addressed the mechanisms involved in its onset, the processes contributing to its recovery have not yet been addressed. Recently, we have found that thrombin is detected at high concentrations in the brain of mice after exposure to mTBI and that in such settings amnesia is rescued by either inhibiting thrombin activity or by blockade of PAR1. Here, we report that mice spontaneously recover from amnesia after two weeks from mTBI exposure. At this time point, long term potentiation was equally evoked in injured vs. control animals with thrombin concentration in the brain being normalized at this stage. These findings, which refer to the specific aspect of memory retrieval upon mTBI, together with our previous work, hint to a strong correlation between cognitive defects in the context of mTBI and thrombin concentrations in the brain. This may suggest that a possible scavenging of thrombin in the brain at early phases following mTBI may improve memory function. PMID- 29182654 TI - Knowledge, attitudes and behaviours of women regarding breast and cervical cancer in Malatya, Turkey. AB - The aim of this study is to gather information about the knowledge, attitudes and behaviours of women regarding breast and cervical cancer, to increase the knowledge level of the relevant age group and to begin including the relevant age group in screening programs. This cross-sectional study is composed of 6910 women aged 30-69 years in Malatya, Turkey. The study aimed to reach 1782 women with a survey, and all of them were reached. The questionnaire form was completed with face-to-face interview. For statistical analysis, data were evaluated as number and percentage distributions. The average age of the women was 45.6+/-11.4. Nearly half of the women (46.4%) did not know that scans for early detection of breast and cervical cancers were free. Only 22.2% of women knew that breast cancer could be diagnosed early by mammography. 72.7% had never received a mammogram. One third (31.6%) of women did not know it was possible to recognize cervical cancer early, and two thirds (64.5%) of women had not received a Pap smear test. It has been determined that Turkish women do not have adequate knowledge about cancer diagnosis, early cancer diagnosis, and screening. PMID- 29182655 TI - A mechanistic model for spread of livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) within a pig herd. AB - Before an efficient control strategy for livestock-associated methicillin resistant Staphylococcus aureus (LA-MRSA) in pigs can be decided upon, it is necessary to obtain a better understanding of how LA-MRSA spreads and persists within a pig herd, once it is introduced. We here present a mechanistic stochastic discrete-event simulation model for spread of LA-MRSA within a farrow to-finish sow herd to aid in this. The model was individual-based and included three different disease compartments: susceptible, intermittent or persistent shedder of MRSA. The model was used for studying transmission dynamics and within farm prevalence after different introductions of LA-MRSA into a farm. The spread of LA-MRSA throughout the farm mainly followed the movement of pigs. After spread of LA-MRSA had reached equilibrium, the prevalence of LA-MRSA shedders was predicted to be highest in the farrowing unit, independent of how LA-MRSA was introduced. LA-MRSA took longer to spread to the whole herd if introduced in the finisher stable, rather than by gilts in the mating stable. The more LA-MRSA positive animals introduced, the shorter time before the prevalence in the herd stabilised. Introduction of a low number of intermittently shedding pigs was predicted to frequently result in LA-MRSA fading out. The model is a potential decision support tool for assessments of short and long term consequences of proposed intervention strategies or surveillance options for LA-MRSA within pig herds. PMID- 29182656 TI - Assessment of the prognostic value of the 8th AJCC staging system for patients with clinically staged prostate cancer; A time to sub-classify stage IV? AB - BACKGROUND: The American Joint Committee on Cancer (AJCC) staging system (8th edition) for prostate cancer has been published. The current study seeks to validate the prognostic performance of the changes in the new system among clinically staged prostate cancer patients registered within the surveillance, epidemiology and end results (SEER) database. METHODS: SEER database (2004-2014) has been accessed through SEER*Stat program and AJCC 7th and 8th edition stages were calculated utilizing T, N and M stages as well as baseline prostatic specific antigen (PSA) and grade group. Cancer-specific and overall survival analyses according to 6th, 7th and 8th editions were conducted through Kaplan Meier analysis. Moreover, multivariate analysis was conducted through a Cox proportional hazard model. RESULTS: A total of 110499 patients with prostate cancer were identified in the period from 2004-2014.For cancer- specific survival according to 8th AJCC, all pair wise P values for comparison were significant (<0.01) except for stage IIA vs. IIB; while for overall survival according to 8th AJCC, all pair wise P values for comparison were significant (<0.02) except for stage IIIA vs. IIIB. Results of c-index assessment for cancer-specific survival for the three AJCC editions were as follows: c-index for AJCC 6th edition was 0.816; c-index for AJCC 7th edition was 0.897; c-index for AJCC 8th edition was 0.907. For stage IVB prostate cancer (i.e.M1 disease), further sub-staging was proposed according to M1 sub-stage (i.e. M1a, M1b and M1c). Pair wise comparison between these proposed sub-stages was conducted for both cancer-specific and overall survival. For both cancer-specific and overall survival, all pair wise P values for comparisons were <0.0001. CONCLUSION: Compared to older staging systems (6th and 7th), the 8th system is more discriminatory. Further sub classification of stage IV disease is suggested. PMID- 29182657 TI - Accuracy and reproducibility of CT right-to-left ventricular diameter measurement in patients with acute pulmonary embolism. AB - BACKGROUND: Right ventricular (RV) dysfunction caused by acute pulmonary embolism (PE) is associated with poor short- and long-term prognosis. RV dilatation as a proxy for RV dysfunction can be assessed by calculating the right-to-left ventricle diameter (RV/LV) ratio on standard computed tomography pulmonary angiography (CTPA) images. It is unknown whether dedicated training is required to accurately and reproducibly measure RV/LV ratio therefore we aimed to assess these parameters in residents in internal medicine without experience in CTPA reading. METHODS: CTPA images of 100 patients with PE were assessed by three residents after single instruction, and one experienced thoracic radiologist. Maximum diameters were evaluated in the axial view by measuring the distance between the ventricular endocardium and the interventricular septum, perpendicular to the long axis of the heart. RV dilatation was defined as a ratio of >=1.0. Interobserver accuracy and reproducibility was determined using Kappa statistics, Bland-Altman analysis and Spearman's rank correlation. RESULTS: The kappa statistic for the presence of RV dilatation of the residents compared to the experienced radiologist ranged from 0.83-0.94. The average interobserver difference in calculated RV/LV ratio's (+/-SD) between the three residents was: 0.01 (SD0.11), 0.07 (SD0.14) and 0.06 (SD0.18) with an overall mean RV/LV diameter ratio of 1.04. In line with this, Spearman's rank correlation coefficients were 0.92, 0.88 and 0.85 respectively indicating very good correlation (p<0.01 for all). CONCLUSION: After simple instruction, RV/LV diameter ratio assessment on CTPA images by clinical residents is accurate and reproducible, which is of help in identifying PE patients at risk. PMID- 29182658 TI - High-permeability region size on perfusion CT predicts hemorrhagic transformation after intravenous thrombolysis in stroke. AB - OBJECTIVE: Blood-brain barrier (BBB) permeability has been proposed as a predictor of hemorrhagic transformation (HT) after tissue plasminogen activator (tPA) administration; however, the reliability of perfusion computed tomography (PCT) permeability imaging for predicting HT is uncertain. We aimed to determine the performance of high-permeability region size on PCT (HPrs-PCT) in predicting HT after intravenous tPA administration in patients with acute stroke. METHODS: We performed a multimodal CT protocol (non-contrast CT, PCT, CT angiography) to prospectively study patients with middle cerebral artery occlusion treated with tPA within 4.5 hours of symptom onset. HT was graded at 24 hours using the European-Australasian Acute Stroke Study II criteria. ROC curves selected optimal volume threshold, and multivariate logistic regression analysis identified predictors of HT. RESULTS: The study included 156 patients (50% male, median age 75.5 years). Thirty-seven (23,7%) developed HT [12 (7,7%), parenchymal hematoma type 2 (PH-2)]. At admission, patients with HT had lower platelet values, higher NIHSS scores, increased ischemic lesion volumes, larger HPrs-PCT, and poorer collateral status. The negative predictive value of HPrs-PCT at a threshold of 7mL/100g/min was 0.84 for HT and 0.93 for PH-2. The multiple regression analysis selected HPrs-PCT at 7mL/100g/min combined with platelets and baseline NIHSS score as the best model for predicting HT (AUC 0.77). HPrs-PCT at 7mL/100g/min was the only independent predictor of PH-2 (OR 1, AUC 0.68, p = 0.045). CONCLUSIONS: HPrs-PCT can help predict HT after tPA, and is particularly useful in identifying patients at low risk of developing HT. PMID- 29182659 TI - Fractal analyses reveal independent complexity and predictability of gait. AB - Locomotion is a natural task that has been assessed for decades and used as a proxy to highlight impairments of various origins. So far, most studies adopted classical linear analyses of spatio-temporal gait parameters. Here, we use more advanced, yet not less practical, non-linear techniques to analyse gait time series of healthy subjects. We aimed at finding more sensitive indexes related to spatio-temporal gait parameters than those previously used, with the hope to better identify abnormal locomotion. We analysed large-scale stride interval time series and mean step width in 34 participants while altering walking direction (forward vs. backward walking) and with or without galvanic vestibular stimulation. The Hurst exponent alpha and the Minkowski fractal dimension D were computed and interpreted as indexes expressing predictability and complexity of stride interval time series, respectively. These holistic indexes can easily be interpreted in the framework of optimal movement complexity. We show that alpha and D accurately capture stride interval changes in function of the experimental condition. Walking forward exhibited maximal complexity (D) and hence, adaptability. In contrast, walking backward and/or stimulation of the vestibular system decreased D. Furthermore, walking backward increased predictability (alpha) through a more stereotyped pattern of the stride interval and galvanic vestibular stimulation reduced predictability. The present study demonstrates the complementary power of the Hurst exponent and the fractal dimension to improve walking classification. Our developments may have immediate applications in rehabilitation, diagnosis, and classification procedures. PMID- 29182661 TI - Classical and next generation sequencing approaches unravel Bymovirus diversity in barley crops in France. AB - Despite the generalized use of cultivars carrying the rym4 resistance gene, the impact of viral mosaic diseases on winter barleys increased in recent years in France. This change could reflect i) an increased prevalence of the rym4 resistance-breaking pathotype of Barley yellow mosaic virus Y (BaYMV-2), ii) the emergence of rym4 resistance-breaking pathotypes of Barley mild mosaic virus (BaMMV) or iii) the emergence of other viruses. A study was undertaken to determine the distribution and diversity of viruses causing yellow mosaic disease. A collection of 241 symptomatic leaf samples from susceptible, rym4 and rym5 varieties was gathered from 117 sites. The viruses present in all samples were identified by specific RT-PCR assays and, for selected samples, by double stranded RNA next-generation sequencing (NGS). The results show that BaYMV-2 is responsible for the symptoms observed in varieties carrying the resistance gene rym4. In susceptible varieties, both BaYMV-1 and BaYMV-2 were detected, together with BaMMV. Phylogenetic analyses indicate that the rym4 resistance-breaking ability independently evolved in multiple genetic backgrounds. Parallel analyses revealed a similar scenario of multiple independent emergence events in BaMMV for rym5 resistance-breaking, likely involving multiple amino acid positions in the viral-linked genome protein. NGS analyses and classical techniques provided highly convergent results, highlighting and validating the power of NGS approaches for diagnostics and viral population characterization. PMID- 29182660 TI - Interaction between TCF7L2 polymorphism and dietary fat intake on high density lipoprotein cholesterol. AB - Recent evidence suggests that lifestyle factors influence the association between the Melanocortin 4 receptor (MC4R) and Transcription Factor 7-Like 2 (TCF7L2) gene variants and cardio-metabolic traits in several populations; however, the available research is limited among the Asian Indian population. Hence, the present study examined whether the association between the MC4R single nucleotide polymorphism (SNP) (rs17782313) and two SNPs of the TCF7L2 gene (rs12255372 and rs7903146) and cardio-metabolic traits is modified by dietary factors and physical activity. This cross sectional study included a random sample of normal glucose tolerant (NGT) (n = 821) and participants with type 2 diabetes (T2D) (n = 861) recruited from the urban part of the Chennai Urban Rural Epidemiology Study (CURES). A validated food frequency questionnaire (FFQ) was used for dietary assessment and self-reported physical activity measures were collected. The threshold for significance was set at P = 0.00023 based on Bonferroni correction for multiple testing [(0.05/210 (3 SNPs x 14 outcomes x 5 lifestyle factors)]. After Bonferroni correction, there was a significant interaction between the TCF7L2 rs12255372 SNP and fat intake (g/day) (Pinteraction = 0.0001) on high density lipoprotein cholesterol (HDL-C), where the 'T' allele carriers in the lowest tertile of total fat intake had higher HDL-C (P = 0.008) and those in the highest tertile (P = 0.017) had lower HDL-C compared to the GG homozygotes. In a secondary analysis of SNPs with the subtypes of fat, there was also a significant interaction between the SNP rs12255372 and polyunsaturated fatty acids (PUFA, g/day) (Pinteraction<0.0001) on HDL-C, where the minor allele carriers had higher HDL-C in the lowest PUFA tertile (P = 0.024) and those in the highest PUFA tertile had lower HDL-C (P = 0.028) than GG homozygotes. In addition, a significant interaction was also seen between TCF7L2 SNP rs12255372 and fibre intake (g/day) on HDL-C (Pinteraction<0.0001). None of the other interactions between the SNPs and lifestyle factors were statistically significant after correction for multiple testing. Our findings indicate that the association between TCF7L2 SNP rs12255372 and HDL-C may be modified by dietary fat intake in this Asian Indian population.

AB - Including threats in spatial conservation prioritization helps identify areas for conservation actions where biodiversity is at imminent risk of extinction. At the global level, an important limitation when identifying spatial priorities for conservation actions is the lack of information on the spatial distribution of threats. Here, we identify spatial conservation priorities under three prominent threats to biodiversity (residential and commercial development, agricultural expansion, and forest loss), which are primary drivers of habitat loss and threaten the persistence of the highest number of species in the International Union for the Conservation of Nature (IUCN) Red List, and for which spatial data is available. We first explore how global priority areas for the conservation of vertebrate (mammals, birds, and amphibians) species coded in the Red List as vulnerable to each threat differ spatially. We then identify spatial conservation priorities for all species vulnerable to all threats. Finally, we identify the potentially most threatened areas by overlapping the identified priority areas for conservation with maps for each threat. We repeat the same with four other well-known global conservation priority area schemes, namely Key Biodiversity Areas, Biodiversity Hotspots, the global Protected Area Network, and Wilderness Areas. We find that residential and commercial development directly threatens only about 4% of the global top 17% priority areas for species vulnerable under this threat. However, 50% of the high priority areas for species vulnerable to forest loss overlap with areas that have already experienced some forest loss. Agricultural expansion overlapped with ~20% of high priority areas. Biodiversity Hotspots had the greatest proportion of their total area under direct threat from all threats, while expansion of low intensity agriculture was found to pose an imminent threat to Wilderness Areas under future agricultural expansion. Our results identify areas where limited resources should be allocated to mitigate risks to vertebrate species from habitat loss.

AB - Inattention in childhood is associated with academic problems later in life. The contribution of specific aspects of inattentive behaviour is, however, less known. We investigated feature importance of primary school teachers' reports on nine aspects of inattentive behaviour, gender and age in predicting future academic achievement. Primary school teachers of n = 2491 children (7-9 years) rated nine items reflecting different aspects of inattentive behaviour in 2002. A mean academic achievement score from the previous semester in high school (2012) was available for each youth from an official school register. All scores were at a categorical level. Feature importances were assessed by using multinominal logistic regression, classification and regression trees analysis, and a random forest algorithm. Finally, a comprehensive pattern classification procedure using k-fold cross-validation was implemented. Overall, inattention was rated as more severe in boys, who also obtained lower academic achievement scores in high school than girls. Problems related to sustained attention and distractibility were together with age and gender defined as the most important features to predict future achievement scores. Using these four features as input to a collection of classifiers employing k-fold cross-validation for prediction of academic achievement level, we obtained classification accuracy, precision and recall that were clearly better than chance levels. Primary school teachers' reports of problems related to sustained attention and distractibility were identified as the two most important features of inattentive behaviour predicting academic achievement in high school. Identification and follow-up procedures of primary school children showing these characteristics should be prioritised to prevent future academic failure.

AB - The role of natural killer (NK; CD3-CD56+)/NKT (CD3+CD56+)-like cells in chikungunya virus (CHIKV) disease progression/recovery remains unclear. Here, we investigated the expression profiles and function of NK and NKT-like cells from 35 chronic chikungunya patients, 30 recovered individuals, and 69 controls. Percentage of NKT-like cells was low in chronic chikungunya patients. NKp30+, CD244+, DNAM-1+, and NKG2D+ NK cell percentages were also lower (MFI and/or percentage), while those of CD94+ and NKG2A+ NKT-like cells were higher (MFI and/or percentage) in chronic patients than in recovered subjects. IFN-gamma and TNF-alpha expression on NKT-like cells was high in the chronic patients, while only IFN-gamma expression on NK cells was high in the recovered individuals. Furthermore, percentage of perforin+NK cells was low in the chronic patients. Lower cytotoxic activity was observed in the chronic patients than in the controls. CD107a expression on NK and NKT-like cells post anti-CD94/anti-NKG2A blocking was comparable among the patients and controls. Upregulated inhibitory and downregulated activating NK receptor expressions on NK/NKT-like cells, lower perforin+ and CD107a+NK cells are likely responsible for inhibiting the NK and NKT-like cell function in the chronic stage of chikungunya. Therefore, deregulation of NKR expression might underlie CHIKV-induced chronicity. PMID- 29182665 TI - The role of protease inhibitors on the remineralization of demineralized dentin using the PILP method. AB - Mineralized and sound dentin matrices contain inactive preforms of proteolytic enzymes that may be activated during the demineralization cycle. In this study, we tested the hypothesis that protease inhibitors (PI) preserve demineralized collagen fibrils and other constituents of the dentin matrix and thereby affect the potential for remineralization. Artificial carious lesions with lesion depths of 140 MUm were created with acetate buffer (pH = 5.0, 66 hours), and remineralized using a polymer-induced-liquid-precursor (PILP) process (pH = 7.4, 14 days) containing poly(aspartic acid) (pAsp) as the process-directing agent. De and remineralizing procedures were performed in the presence or absence of PI. Ultrastructure and mechanical recovery of demineralized dentin following PILP remineralization were examined and measured in water with atomic force microscopy (AFM) and nanoindentation. Nanomechanical properties of hydrated artificial lesions had a low elastic modulus (ER <0.4 GPa) extending about 100 MUm into the lesion, followed by a sloped region of about 140 MUm depth where values reached those of normal dentin (18.0-20.0 GPa). Mapping of mineral content by both micro FTIR and micro x-ray computed tomography correlated well with modulus profiles obtained by nanoindentation. Tissue demineralized in the presence of PI exhibited higher elastic moduli (average 2.8 GPa) across the lesion and comprised a narrow zone in the outer lesion with strongly increased modulus (up to 8 GPa; p < 0.05), which might be related to the preservation of non-collagenous proteins that appear to induce calcium phosphate mineral formation even under demineralizing physical-chemical conditions. However, mechanical aspects of remineralization through the elastic modulus change, and the micromorphological aspects with SEM and TEM observation were almost identical with PILP treatments being conducted in the presence or absence of PI. Thus, the application of the protease inhibitors (PI) seemed to be less effective in promoting the remineralization of demineralized dentin. PMID- 29182666 TI - GnRH receptor gene mutations in adolescents and young adults presenting with signs of partial gonadotropin deficiency. AB - Biallelic, partial loss-of-function mutations in GNRHR cause a wide spectrum of reproductive phenotypes from constitutional delay of growth and puberty to complete congenital hypogonadotropic hypogonadism. We studied the frequency of GNRHR, FGFR1, TAC3, and TACR3 mutations in nine adolescent and young adult females with clinical cues consistent with partial gonadotropin deficiency (stalled puberty, unexplained secondary amenorrhea), and describe phenotypic features and molecular genetic findings of monozygotic twin brothers with stalled puberty. Two girls out of nine (22%, 95%CI 6-55%) carried biallelic mutations in GNRHR. The girl with compound heterozygous c.317A>G p.(Gln106Arg) and c.924_926delCTT p.(Phe309del) GNRHR mutations displayed incomplete puberty and clinical signs of hypoestrogenism. The patient carrying a homozygous c.785G>A p.(Arg262Gln) mutation presented with signs of hypoestrogenism and unexplained secondary amenorrhea. None of the patients exhibited mutations in FGFR1, TAC3, or TACR3. The twin brothers, compound heterozygous for GNRHR mutations c.317A>G p.(Gln106Arg) and c.785G>A p.(Arg262Gln), presented with stalled puberty and were discordant for weight, and the heavier of them had lower testosterone levels. These results suggest that genetic testing of the GNRHR gene should be offered to adolescent females with low-normal gonadotropins and unexplained stalled puberty or menstrual dysfunction. In male patients with partial gonadotropin deficiency, excess adipose tissue may suppress hypothalamic-pituitary-gonadal axis. PMID- 29182667 TI - Heat shock proteins HSPB8 and DNAJC5B have HCV antiviral activity. AB - Hepatitis C is a disease caused by the hepatitis C virus (HCV), and an estimated 3% of the world population is infected with the virus. During replication, HCV interacts with several cellular proteins. Studies have shown that several heat shock proteins (HSPs) have an altered expression profile in the presence of the virus, and some HSPs interact directly with HCV proteins. In the present study, we evaluated the expression levels of heat shock proteins in vitro in the presence and absence of HCV. The differential expression of 84 HSPs and chaperones was observed using a qPCR array, comparing HCV uninfected and infected Huh7.5 cells. To validate qPCR array, the differentially expressed genes were tested by real-time PCR in three different HCV models: subgenomic HCV replicon cells (SGR-JFH-1), JFH-1 infected cells (both genotype 2a) and subgenomic S52 cells (genotype 3). The HSPB8 gene showed increased expression in all three viral models. We silenced HSPB8 expression and observed an increase in viral replication. In contrast, when we increased the expression of HSPB8, a decrease in the HCV replication rate was observed. The same procedure was adopted for DNAJC5B, and HCV showed a similar replication pattern as that observed for HSPB8. These results suggest that HSPB8 may act as an intracellular factor against hepatitis C virus replication and that DNAJC5B has the same function, with more relevant results for genotype 3. We also evaluated the direct interactions between HCV and HSP proteins, and the IP experiments showed that the HCV NS4B protein interacts with HSPB8. These results contribute to a better understanding of the mechanisms involved in HCV replication. PMID- 29182668 TI - Extracellular vesicles released by fibroblasts undergoing H-Ras induced senescence show changes in lipid profile. AB - Cells release extracellular vesicles (EVs) in their environment and cellular lipids play an important role in their formation, secretion and uptake. Besides, there is also evidence that EV transferred lipids impact on recipient's cell signaling. Cellular senescence is characterized by a state of permanent proliferation arrest and represents a barrier towards the development of neoplastic lesions. A peculiar feature of senescence is the release of many soluble factors, the so-called Senescence-Associated Secretory Phenotype, which play a key role in triggering paracrine senescence signals. Recently, evidences have suggested that this phenotype includes not only soluble factors, but also EVs. To identify lipid signatures associated with H-Ras-induced senescence in EVs, we expressed active H-Ras (H-RasV12) in human fibroblasts and investigated how it affects EV release and lipid composition. An enrichment of hydroxylated sphingomyelin, lyso- and ether-linked phospholipids and specific H-Ras-induced senescence signatures, e.g. sphingomyelin, lysophosphatidic acid and sulfatides, were found in EVs compared to cells. Furthermore, H-RasV12 expression in fibroblasts was associated with higher levels of tetraspanins involved in vesicle formation. PMID- 29182671 TI - Clustering of samples and variables with mixed-type data. AB - Analysis of data measured on different scales is a relevant challenge. Biomedical studies often focus on high-throughput datasets of, e.g., quantitative measurements. However, the need for integration of other features possibly measured on different scales, e.g. clinical or cytogenetic factors, becomes increasingly important. The analysis results (e.g. a selection of relevant genes) are then visualized, while adding further information, like clinical factors, on top. However, a more integrative approach is desirable, where all available data are analyzed jointly, and where also in the visualization different data sources are combined in a more natural way. Here we specifically target integrative visualization and present a heatmap-style graphic display. To this end, we develop and explore methods for clustering mixed-type data, with special focus on clustering variables. Clustering of variables does not receive as much attention in the literature as does clustering of samples. We extend the variables clustering methodology by two new approaches, one based on the combination of different association measures and the other on distance correlation. With simulation studies we evaluate and compare different clustering strategies. Applying specific methods for mixed-type data proves to be comparable and in many cases beneficial as compared to standard approaches applied to corresponding quantitative or binarized data. Our two novel approaches for mixed-type variables show similar or better performance than the existing methods ClustOfVar and bias corrected mutual information. Further, in contrast to ClustOfVar, our methods provide dissimilarity matrices, which is an advantage, especially for the purpose of visualization. Real data examples aim to give an impression of various kinds of potential applications for the integrative heatmap and other graphical displays based on dissimilarity matrices. We demonstrate that the presented integrative heatmap provides more information than common data displays about the relationship among variables and samples. The described clustering and visualization methods are implemented in our R package CluMix available from https://cran.r-project.org/web/packages/CluMix. PMID- 29182669 TI - NKT cells contribute to basal IL-4 production but are not required to induce experimental asthma. AB - CD1d-deficiency results in a selective deletion of NKT cells in mice that is reported to prevent murine allergic airway disease (AAD). Because we find 2-3 fold lower basal IL-4 production in CD1d- mice than in wild-type (WT) mice, we hypothesized that the contribution made by NKT cells to AAD would depend on the strength of the stimulus used to induce the disease. Consequently, we compared CD1d-deficient mice to WT mice in the development of AAD, using several models of disease induction that differed in the type and dose of allergen, the site of sensitization and the duration of immunization. Surprisingly we found equivalent allergic inflammation and airway disease in WT and CD1d- mice in all models investigated. Consistent with this, NKT cells constituted only ~2% of CD4+ T cells in the lungs of mice with AAD, and IL-4-transcribing NKT cells did not expand with disease induction. Concerned that the congenital absence of NKT cells might have caused a compensatory shift within the immune response, we administered an anti-CD1d monoclonal Ab (mAb) to block NKT function before airway treatments, before or after systemic sensitization to antigen. Such Ab treatment did not affect disease severity. We suggest that the differences reported in the literature regarding the significance of NKT cells in the induction of allergic airway disease may have less to do with the methods used to study the disease and more to do with the animals themselves and/or the facilities used to house them. PMID- 29182670 TI - Diversity and potential activity of methanotrophs in high methane-emitting permafrost thaw ponds. AB - Lakes and ponds derived from thawing permafrost are strong emitters of carbon dioxide and methane to the atmosphere, but little is known about the methane oxidation processes in these waters. Here we investigated the distribution and potential activity of aerobic methanotrophic bacteria in thaw ponds in two types of eroding permafrost landscapes in subarctic Quebec: peatlands and mineral soils. We hypothesized that methanotrophic community composition and potential activity differ regionally as a function of the landscape type and permafrost degradation stage, and locally as a function of depth-dependent oxygen conditions. Our analysis of pmoA transcripts by Illumina amplicon sequencing and quantitative PCR showed that the communities were composed of diverse and potentially active lineages. Type I methanotrophs, particularly Methylobacter, dominated all communities, however there was a clear taxonomic separation between the two landscape types, consistent with environmental control of community structure. In contrast, methanotrophic potential activity, measured by pmoA transcript concentrations, did not vary with landscape type, but correlated with conductivity, phosphorus and total suspended solids. Methanotrophic potential activity was also detected in low-oxygen bottom waters, where it was inversely correlated with methane concentrations, suggesting methane depletion by methanotrophs. Methanotrophs were present and potentially active throughout the water column regardless of oxygen concentration, and may therefore be resilient to future mixing and oxygenation regimes in the warming subarctic. PMID- 29182673 TI - Ensemble machine learning and forecasting can achieve 99% uptime for rural handpumps. AB - Broken water pumps continue to impede efforts to deliver clean and economically viable water to the global poor. The literature has demonstrated that customers' health benefits and willingness to pay for clean water are best realized when clean water infrastructure performs extremely well (>99% uptime). In this paper, we used sensor data from 42 Afridev-brand handpumps observed for 14 months in western Kenya to demonstrate how sensors and supervised ensemble machine learning could be used to increase total fleet uptime from a best-practices baseline of about 70% to >99%. We accomplish this increase in uptime by forecasting pump failures and identifying existing failures very quickly. Comparing the costs of operating the pump per functional year over a lifetime of 10 years, we estimate that implementing this algorithm would save 7% on the levelized cost of water relative to a sensor-less scheduled maintenance program. Combined with a rigorous system for dispatching maintenance personnel, implementing this algorithm in a real-world program could significantly improve health outcomes and customers' willingness to pay for water services. PMID- 29182672 TI - Increased expression of Th17 cytokines and interleukin-22 correlates with disease activity in pristane-induced arthritis in rats. AB - The objective of this study was to identify the key changed subtype of T helper cells (Th cells) and their cytokines in pristane-induced arthritis (PIA) in rats. The severity of arthritis was evaluated by body weight, clinical score, the perimeter of ankle and mid-paw and histological assessment of ankle joints. Cytokines of Th1, Th2 and Th17 were determined in the spleen and inguinal lymph nodes at 28 days after pristane injection by real-time qPCR. The mRNA levels of IL-22 receptors, IL-22R1 and IL-22BP, in the spleen were quantified by real-time qPCR. Additionally, IL-22 expression in synovial membrane was detected by Western blotting, and serum IL-22 concentration was determined by ELISA. Correlation between IL-22 concentration and clinical score was analyzed. By screening the cytokines of Th1, Th2 and Th17 expression profile, we found that the mRNA levels of Th17 cytokines were significantly increased in PIA rats. Particularly, a significant increase in the protein expression of IL-22 was determined in synovial membrane and serum from PIA rats, and correlated with clinical score. We conclude that IL-22 expression level was increased and correlated with disease severity, which indicated that IL-22 may play an important role in development of PIA, and was helpful to explorer the pathogenesis of rheumatoid arthritis. PMID- 29182674 TI - Genome-wide analysis of the diversity and ancestry of Korean dogs. AB - There are various hypotheses on dog domestication based on archeological and genetic studies. Although many studies have been conducted on the origin of dogs, the existing literature about the ancestry, diversity, and population structure of Korean dogs is sparse. Therefore, this study is focused on the origin, diversity and population structure of Korean dogs. The study sample comprised four major categories, including non-dogs (coyotes and wolves), ancient, modern and Korean dogs. Selected samples were genotyped using an Illumina CanineHD array containing 173,662 single nucleotide polymorphisms. The genome-wide data were filtered using quality control parameters in PLINK 1.9. Only autosomal chromosomes were used for further analysis. The negative off-diagonal variance of the genetic relationship matrix analysis depicted, the variability of samples in each population. FIS (inbreeding rate within a population) values indicated, a low level of inbreeding within populations, and the patterns were in concordance with the results of Nei's genetic distance analysis. The lowest FST (inbreeding rate between populations) values among Korean and Chinese breeds, using a phylogenetic tree, multi-dimensional scaling, and a TreeMix likelihood tree showed Korean breeds are highly related to Chinese breeds. The Korean breeds possessed a unique and large diversity of admixtures compared with other breeds. The highest and lowest effective population sizes were observed in Korean Jindo Black (485) and Korean Donggyeong White (109), respectively. The historical effective population size of all Korean dogs showed declining trend from the past to present. It is important to take immediate action to protect the Korean dog population while conserving their diversity. Furthermore, this study suggests that Korean dogs have unique diversity and are one of the basal lineages of East Asian dogs, originating from China. PMID- 29182675 TI - An analytical approach to sparse telemetry data. AB - Horizontal behavior of highly migratory marine species is difficult to decipher because animals are wide-ranging, spend minimal time at the ocean surface, and utilize remote habitats. Satellite telemetry enables researchers to track individual movements, but population level inferences are rare due to data limitations that result from difficulty of capture and sporadic tag reporting. We introduce a Bayesian modeling framework to address population level questions with satellite telemetry data when data are sparse. We also outline an approach for identifying informative variables for use within the model. We tested our modeling approach using a large telemetry dataset for Shortfin Makos (Isurus oxyrinchus), which allowed us to assess the effects of various degrees of data paucity. First, a permuted Random Forest analysis is implemented to determine which variables are most informative. Next, a generalized additive mixed model is used to help define the relationship of each remaining variable with the response variable. Using jags and rjags for the analysis of Bayesian hierarchical models using Markov Chain Monte Carlo simulation, we then developed a movement model to generate parameter estimates for each of the variables of interest. By randomly reducing the tagging dataset by 25, 50, 75, and 90 percent and recalculating the parameter estimates, we demonstrate that the proposed Bayesian approach can be applied in data-limited situations. We also demonstrate how two commonly used linear mixed models with maximum likelihood estimation (MLE) can be similarly applied. Additionally, we simulate data from known parameter values to test each model's ability to recapture those values. Despite performing similarly, we advocate using the Bayesian over the MLE approach due to the ability for later studies to easily utilize results of past study to inform working models, and the ability to use prior knowledge via informed priors in systems where such information is available. PMID- 29182676 TI - Reproductive isolation in the acoustically divergent groups of tettigoniid, Mecopoda elongata. AB - Sympatric divergent populations of the same species provide an opportunity to study the evolution and maintenance of reproductive isolation. Male mating calls are important in sexual selection in acoustically communicating species, and they also have the potential to maintain isolation among species or incipient species. We studied divergent south Indian populations of the bush cricket Mecopoda elongata which are extremely difficult to distinguish morphologically, but which exhibit striking divergence in male acoustic signals. We performed phonotactic experiments investigating the relative preference of females of the "Chirper" song type for calls of all 5 of the song types found in the region (in varying degrees of sympatry). We found that Chirper females preferred their own song type and were completely unresponsive to three trilling song types. Chirper females were occasionally attracted to the call type "Double Chirper" (the call most similar to their own type), suggesting call preference alone cannot provide a complete isolating mechanism. To investigate the basis of call preference we investigated the response of chirper females to variation in chirp rate. Chirper females responded most frequently to a mean chirp rate characteristic of their own song type rather than a higher chirp rate which would be more characteristic of the Double-Chirper song type. This suggests females drive stabilising selection on male chirp rate, which may contribute to the maintenance of isolation. Finally, a no-choice mating experiment using Chirper females and Chirper and Double Chirper males revealed a significant preference of Chirper females to mate with their own song type, even without a requirement for phonotaxis. Overall, the strong specificity of Chirper females for their 'own' song type provides evidence for behavioural isolation among divergent sympatric Mecopoda song types being maintained by female preference for both male song type and subsequent mating probability driven by other cues. PMID- 29182677 TI - Arabidopsis ubiquitin ligase PUB12 interacts with and negatively regulates Chitin Elicitor Receptor Kinase 1 (CERK1). AB - In Arabidopsis, fungal chitin is recognized as a pathogen-associated molecular pattern (PAMP) by the chitin receptor complex containing the lysin-motif (LysM) receptor-like kinases CERK1 and LYK5. Upon the perception of chitin, CERK1 phosphorylates the receptor-like cytoplasmic kinase, PBL27, which activates the intracellular mitogen-activated protein kinase (MAPK) cascade. However, the mechanisms by which the CERK1-PBL27 complex is regulated remain largely unknown. We identified ubiquitin ligase PUB12 as a component of the PBL27 complex using co immunoprecipitation and mass spectrometry. However, PUB12 did not interact directly with PBL27. Instead, the ARM domains of PUB12 and its paralog PUB13 interacted with the intracellular domain of CERK1 in a manner that was dependent on its autophosphorylation, suggesting that the phosphorylation-based auto activation of CERK1 may be required for its interaction with PUB12. The co expression of PUB12 in Nicotiana benthamiana reduced the accumulation of CERK1. The pub12 pub13 mutant exhibited enhanced chitin-induced immune responses such as ROS production, MAPK activation, and callose deposition. These results suggest that PUB12 and PUB13 are involved in the negative regulation of the chitin receptor complex, which may contribute to the transient desensitization of chitin induced responses. PMID- 29182678 TI - Diagnostic performance of point-of-care and central laboratory cardiac troponin assays in an emergency department. AB - Early diagnosis of myocardial infarction (MI) with cardiac troponin (cTn) assays at the point-of-care (POC) is suggested to shorten turn-around-time in the emergency department (ED). The present study aimed at comparing the diagnostic performance of two POC cTn assays with that of a central laboratory high sensitivity (hs) method, under routine ED conditions. In 2,163 non-selected ED patients suspected for MI, the diagnostic performance of the POC troponin I (TnI), troponin T (TnT), and hs-TnT assay for the prediction of MI was evaluated based on receiver operating characteristic (ROC) analyses and compared with the performance based on the manufacturers' cut-offs. Due to an observed association between renal function as determined by estimated glomerular filtration rate (eGFR) and cTn concentrations, all analyses were stratified by renal function. In patients with normal renal function (eGFR > 60 mL/min/1.73m2), POC and hs assays showed a comparable diagnostic performance as quantified by the area under the ROC curve (AUC) of about 0.88. The ROC-derived optimal cut-off (OCO) levels for the different cTn assays clearly changed with decreasing kidney function. Impaired kidney function required OCO to be three to five times higher to achieve a comparable performance. Particularly cTnT concentrations were strongly associated with renal function. The three cTn assays demonstrated equivalent diagnostic performance in ED-patients admitted with suspected ACS in relation to the release diagnosis, supporting the use of POC testing in this setting. The present results implicate that application of eGFR-specific OCOs may decrease false-positives among patients with impaired renal function. Providing individual cut-offs depending on patients' eGFR might be an appropriate add-on tool to improve specificity in the diagnosis of MI. PMID- 29182679 TI - The extracellular matrix protein Edil3 stimulates osteoblast differentiation through the integrin alpha5beta1/ERK/Runx2 pathway. AB - Epidermal growth factor-like repeats and discoidin I-like domain 3 (Edil3) is an extracellular matrix protein containing an Arg-Gly-Asp (RGD) motif that binds integrin. Recently, Edil3 has been implicated in various biological processes, including angiogenesis and cellular differentiation. It can inhibit inflammatory bone destruction. The objective of this study was to explore the role of Edil3 in osteoblast differentiation and its underlying molecular mechanisms. In wild-type mice, high expression levels of Edil3 mRNA were observed in isolated calvaria and tibia/femur bones. Immunohistochemical analysis showed that Edil3 protein was localized along periosteum and calcified regions surrounding bone tissues. When murine calvaria-derived MC3T3-E1 cells were cultured in osteogenic medium containing 50 MUg/ml ascorbic acid and 5 mM beta-glycerophosphate, Edil3 mRNA and protein expression levels were increased. Treatment with Edil3 protein in growth media increased expression levels of alkaline phosphatase and osteocalcin gene and phosphorylation level of extracellular signal-regulated kinase (ERK). Edil3 treatment with osteogenic medium induced mineralization. Treatment with a neutralizing antibody against alpha5beta1 and MEK inhibitor U0126 inhibited Edil3 enhanced osteogenic marker gene expression and mineral deposition. Edil3 increased protein expression levels of transcription factor runt-related transcription factor2 (Runx2). Edil3-induced Runx2 protein expression was suppressed by pretreatment with U0126. Taken together, these results suggest that Edil3 may stimulate osteoblast differentiation and matrix mineralization by increasing expression of Runx2 through alpha5beta1 integrin /ERK pathway. PMID- 29182681 TI - Using 13C in cattle hair to trace back the maize level in the feeding regime-A field test. AB - Sections from cattle hair serve as an isotopic archive-they contain information on the cattle diet from different time periods. We tested the reliability of 13C signatures (delta13C) in cattle tail switch hair to retrospectively trace back the annual dietary proportion of maize of different production systems without having to sample and analyze the feed. Furthermore, we investigated if differences in dietary proportion of maize during summer and winter feeding can be detected in a single tail switch hair by sampling hair only once a year. We sampled hair and obtained information on management and annual composition of diets on 23 cattle farms in northern Germany. Farms differed in dietary proportions of maize, grass and concentrates as well as in grazing regime (year round grazing, summer grazing, no grazing). We found that the annual mean delta13C values (delta13CY) of two hair sections that contain the isotopic information of summer and winter feeding is a robust indicator for the annual proportion of maize in cattle diet on a farm. The grazing regimes could clearly be distinguished by analyzing seasonal mean delta13C values (delta13CS). We could also demonstrate short term changes in the diet changes by means of delta13CS. We conclude that the method can be used in different cattle production systems to check on dietary proportions of maize for a period of one year before sampling of hair. PMID- 29182680 TI - Differential activity of 2-methylene-19-nor vitamin D analogs on growth factor gene expression in rhino mouse skin and comparison to all-trans retinoic acid. AB - While all 2-methylene-19-nor analogs of 1alpha,25-dihydroxyvitamin D3 (1alpha,25(OH)2D3) tested produce an increase in epidermal thickness in the rhino mouse, only a subset reduce utricle size (comedolysis). All-trans retinoic acid (atRA) also causes epidermal thickening and a reduction in utricle size in the rhino mouse. We now report that 2-methylene-19-nor-(20S)-1alpha hydroxybishomopregnacalciferol (2MbisP), a comedolytic analog, increases epidermal thickening more rapidly than does atRA, while both reduce utricle area at an equal rate. Whereas unlike atRA, 2MbisP does not alter the epidermal growth factor receptor ligand, heparin-binding epidermal growth factor-like growth factor, it does increase the expression of both amphiregulin and epigen mRNA, even after a single dose. In situ hybridization reveals an increase in these transcripts throughout the closing utricle as well as in the interfollicular epidermis. The mRNAs for other EGFR ligands including betacellulin and transforming growth factor-alpha, as well as the epidermal growth factor receptor are largely unaffected by 2MbisP. Another analog, 2-methylene-19-nor-(20S)-26,27 dimethylene-1alpha,25-dihydroxyvitamin D3 (CAGE-3), produces epidermal thickening but fails to reduce utricle size or increase AREG mRNA levels. CAGE-3 modestly increases epigen mRNA levels, but only after 5 days of dosing. Thus, 2-MbisP produces unique changes in epidermal growth factor receptor ligand mRNAs that may be responsible for both epidermal proliferation and a reduction in utricle size. PMID- 29182683 TI - Principal component and discriminant analyses as powerful tools to support taxonomic identification and their use for functional and phylogenetic signal detection of isolated fossil shark teeth. AB - Identifying isolated teeth of fossil selachians only based on qualitative characters is sometimes hindered by similarity in their morphology, resulting often in heated taxonomic debates. On the other hand, the use of quantitative characters (i.e. measurements) has been often neglected or underestimated in characterization and identification of fossil teeth of selachians. Here we show that, employing a robust methodological protocol based on principal component and discriminant analyses on a sample of 175 isolated fossil teeth of lamniform sharks, the traditional morphometrics can be useful to support and complement the classic taxonomic identification made on qualitative features. Furthermore, we show that discriminant analysis can be successfully useful to assign indeterminate isolated shark teeth to a certain taxon. Finally, the degree of separation of the clusters might be used to predict functional and probably also phylogenetic signals in lamniform shark teeth. However, this needs to be tested in the future employing teeth of more extant and extinct lamniform sharks and it must be pointed out that this approach does not replace in any way the qualitative analysis, but it is intended to complement and support it.

AB - Respiratory syncytial virus (RSV) is recognized as an important cause of lower and upper respiratory tract infections in older adults, and a successful vaccine would substantially lower morbidity and mortality in this age group. Recently, two vaccine candidates based on soluble purified glycoprotein F (RSV F), either alone or adjuvanted with glucopyranosyl lipid A formulated in a stable emulsion (GLA-SE), failed to reach their primary endpoints in clinical efficacy studies, despite demonstrating the desired immunogenicity profile and efficacy in young rodent models. Here, one of the RSV F vaccine candidates (post-fusion conformation, RSV post-F), and a stabilized pre-fusion form of RSV F (RSV pre-F, DS-Cav1) were evaluated in aged BALB/c mice. Humoral and cellular immunogenicity elicited after immunization of naive, aged mice was generally lower compared to young animals. In aged mice, RSV post-F vaccination without adjuvant poorly protected the respiratory tract from virus replication, and addition of GLA-SE only improved protection in the lungs, but not in nasal turbinates. RSV pre-F induced higher neutralizing antibody titers compared to RSV post-F (as previously reported) but interestingly, RSV F-specific CD8 T cell responses were lower compared to RSV post-F responses regardless of age. The vaccines were also tested in RSV seropositive aged mice, in which both antigen forms similarly boosted neutralizing antibody titers, although GLA-SE addition boosted neutralizing activity only in RSV pre-F immunized animals. Cell-mediated immune responses in the aged mice were only slightly boosted and well below levels induced in seronegative young mice. Taken together, the findings suggest that the vaccine candidates were not able to induce a strong anti-RSV immune response in recipient mice with an aged immune system, in agreement with recent human clinical trial results. Therefore, the aged mouse model could be a useful tool to evaluate improved vaccine candidates, targeted to prevent RSV disease in older adults.

AB - Colorectal cancer (CRC) is the third most common cancer and the second leading cause of cancer-related deaths in the United States. The purpose of this study was to evaluate the gene expression differences in different stages of CRC. Gene expression data on 433 CRC patient samples were obtained from The Cancer Genome Atlas (TCGA). Gene expression differences were evaluated across CRC stages using linear regression. Genes with p<=0.001 in expression differences were evaluated further in principal component analysis and genes with p<=0.0001 were evaluated further in gene set enrichment analysis. A total of 377 patients with gene expression data in 20,532 genes were included in the final analysis. The numbers of patients in stage I through IV were 59, 147, 116 and 55, respectively. NEK4 gene, which encodes for NIMA related kinase 4, was differentially expressed across the four stages of CRC. The stage I patients had the highest expression of NEK4 genes, while the stage IV patients had the lowest expressions (p = 9*10-6). Ten other genes (RNF34, HIST3H2BB, NUDT6, LRCh4, GLB1L, HIST2H4A, TMEM79, AMIGO2, C20orf135 and SPSB3) had p value of 0.0001 in the differential expression analysis. Principal component analysis indicated that the patients from the 4 clinical stages do not appear to have distinct gene expression pattern. Network based and pathway-based gene set enrichment analyses showed that these 11 genes map to multiple pathways such as meiotic synapsis and packaging of telomere ends, etc. Ten of these 11 genes were linked to Gene Ontology terms such as nucleosome, DNA packaging complex and protein-DNA interactions. The protein complex-based gene set analysis showed that four genes were involved in H2AX complex II. This study identified a small number of genes that might be associated with clinical stages of CRC. Our analysis was not able to find a molecular basis for the current clinical staging for CRC based on the gene expression patterns. PMID- 29182686 TI - Vertical organization of the division of labor within nests of the Florida harvester ant, Pogonomyrmex badius. AB - In the Florida harvester ant, Pogonomyrmex badius, foragers occur only in the top 15 cm of the nest, whereas brood and brood-care workers reside mostly in the deepest regions, yet the food and seeds foragers collect must be transported downward 30 to 80 cm to seed chambers and up to 2 m to brood chambers. Using mark recapture techniques with fluorescent printer's ink, we identified a class of workers that ranges widely within the vertical structure of the nest, rapidly moving materials dropped by foragers in the upper regions downward, and excavated soil from deeper upward. Within the nest, only 5% of foragers were recovered below 20 cm depth, but about 30% of transfer workers and 82% of unmarked workers were found there. Below 70 cm depth, 90% of workers were unmarked, and were probably involved mostly in brood care. During the summer, the transfer workers comprise about a quarter of the nest population, while foragers make up about 40%. Workers marked as transfer workers later appear as foragers, while those marked as foragers die and disappear from the foraging population, suggesting that transfer workers are younger, and age into foraging. The importance of these findings for laboratory studies of division of labor are discussed. The efficient allocation of labor is a key component of superorganismal fitness. PMID- 29182685 TI - miR205 inhibits stem cell renewal in SUM159PT breast cancer cells. AB - miR205 has a dual activity, as tumor suppressor and as oncogene. Here we analyzed the impact of miR205 ectopic expression in the initial tumorigenic processes of SUM159PT, a triple negative breast cancer cell line with low endogenous levels of miR205. In SUM159PT, miR205 inhibited expression of its targets VEGFA, ErbB3, Zeb1, Fyn and Lyn A/B; it reduced cell proliferation, and Myc/cyclin D1 levels, while increased p27kip1 expression. miR205 abolished anchorage-independent growth, inhibited migration and invasion, Src-kinases/Stat3 axis activation, and levels of secreted MMP9. miR205 also reduced expression of CD44 and TAZ, E2A.E12, Twist, Snail1 and CK5, associated with epithelial-mesenchymal transition (EMT). Importantly, we show that miR205 inhibited SUM159PT cancer-stem cell renewal, expression in mammospheres of CD44 and ALDH1 stem-cell markers, TAZ, and E2A.E12. All these effects of miR205 were reverted by Anti-miR205 co-expression, demonstrating its specificity. Thus, all these results strongly suggest that ectopic expression of miR205 in SUM159PT affected several parameters associated with initial steps of tumorigenesis. PMID- 29182687 TI - Semi-automatic tracking, smoothing and segmentation of hyoid bone motion from videofluoroscopic swallowing study. AB - Motion analysis of the hyoid bone via videofluoroscopic study has been used in clinical research, but the classical manual tracking method is generally labor intensive and time consuming. Although some automatic tracking methods have been developed, masked points could not be tracked and smoothing and segmentation, which are necessary for functional motion analysis prior to registration, were not provided by the previous software. We developed software to track the hyoid bone motion semi-automatically. It works even in the situation where the hyoid bone is masked by the mandible and has been validated in dysphagia patients with stroke. In addition, we added the function of semi-automatic smoothing and segmentation. A total of 30 patients' data were used to develop the software, and data collected from 17 patients were used for validation, of which the trajectories of 8 patients were partly masked. Pearson correlation coefficients between the manual and automatic tracking are high and statistically significant (0.942 to 0.991, P-value<0.0001). Relative errors between automatic tracking and manual tracking in terms of the x-axis, y-axis and 2D range of hyoid bone excursion range from 3.3% to 9.2%. We also developed an automatic method to segment each hyoid bone trajectory into four phases (elevation phase, anterior movement phase, descending phase and returning phase). The semi-automatic hyoid bone tracking from VFSS data by our software is valid compared to the conventional manual tracking method. In addition, the ability of automatic indication to switch the automatic mode to manual mode in extreme cases and calibration without attaching the radiopaque object is convenient and useful for users. Semi-automatic smoothing and segmentation provide further information for functional motion analysis which is beneficial to further statistical analysis such as functional classification and prognostication for dysphagia. Therefore, this software could provide the researchers in the field of dysphagia with a convenient, useful, and all-in-one platform for analyzing the hyoid bone motion. Further development of our method to track the other swallowing related structures or objects such as epiglottis and bolus and to carry out the 2D curve registration may be needed for a more comprehensive functional data analysis for dysphagia with big data. PMID- 29182689 TI - A novel strategy to construct Janus metallamacrocycles with both a Ru-arene face and an imidazolium face. AB - The bottom-up construction of highly functional metallamacrocycles from simple building blocks is a challenge of much current interest. We have used solvothermal reactions of a bifunctional p-bitmb ligand with [Ru(arene)X2]2 in CH2Cl2 or CH2Br2 to generate the novel mononuclear metallamacrocyclic [RuX(arene)L2CH2]X3 complexes 1-3 (1, arene = p-cym, X = Cl; 2, arene = bip, X = Cl; 3, arene = p-cym, X = Br), which were characterized by various techniques. These complexes are "bowl-like" and have two faces: one coordinative Ru centre (arene)Ru(N,N)X bridged by L (L = 1,4-bis(imidazol-1-ylmethyl)-2,3,5,6 tetramethylbenzene, p-bitmb) to a dipositive bis-imidazolinium centre. Cl- or Br- anions can be trapped inside the cavity of the "bowl-like" structure, forming H bonds with the backbone. Experimental (NMR and ESI-MS) and computational (DFT calculations) studies show that the source of the bridging -CH2- group is the dihalogenated solvent (CH2Cl2 or CH2Br2) that links the two arms of an initially formed non-cyclic complex (arene)RuX2L2 by a mechanism of nucleophilic substitution. Optimization of the reaction conditions afforded the macrocyclic complexes in almost quantitative yields. The applications of these complexes as anti-proliferative agents towards cancer cells and for selective anion sensing have been explored. PMID- 29182690 TI - Improving the mass transport of copper-complex redox mediators in dye-sensitized solar cells by reducing the inter-electrode distance. AB - In this work, we study the influence of the distance between electrodes on the performance of dye-sensitized solar cells based on TiO2 using the organic dye LEG4 and a Cu(dmp)2 redox couple (dmp = dimethyl phenantroline). The solar cells are characterized by a large open circuit voltage of up to 1.03 V, and an efficiency of 8.2% has been achieved for a 5.3 MUm thick TiO2 film using an epoxy resin-based sealed cell configuration with a minimal separation between electrodes. Transient short-circuit photocurrent measurements up to an intensity of 3 Suns show a significant decay in photocurrent after an initial peak current upon switching on the light for larger distance, resulting in a lower steady state photocurrent. For the smaller distance cells, the steady state photocurrent is linear with light intensity up to 2 Suns. Charge extraction measurements under short-circuit conditions show that reducing the distance between electrodes increases the electron collection efficiency and thus, the attainable photocurrent. Recombination losses increase with larger electrode separation distance and higher light intensity due to mass transport limitation of the redox mediator. Electrochemical impedance measurements confirm the effect of electrode distance on the redox couple transport, showing an additional loop with increasing distance. For the configuration where the TiO2 film is in very close proximity to the PEDOT-covered counter electrode, inductive behavior is observed at low frequencies. The inductive behavior disappears with the incorporation of an insulating porous ZrO2 layer. The equivalent circuit for the solar cell has been expanded to include this effect. PMID- 29182691 TI - Huge enhancement of upconversion luminescence by dye/Nd3+ sensitization of quenching-shield sandwich structured upconversion nanocrystals under 808 nm excitation. AB - Lanthanide-doped upconversion nanoparticles (UCNPs) have shown potential applications in diverse fields. However, their upconversion luminescence (UCL) intensity and excitation wavelength range are limited by the weak and narrowband absorption of lanthanide ions. Herein, we introduce and validate a strategy to largely increase the absorptivity and upconversion luminescence intensity under 808 nm excitation by broadband dye-sensitized quenching-shield sandwich structured upconversion nanocrystals NaLuF4:Gd,Yb,Tm@NaLuF4:Gd,Yb@NaNdF4:Yb. The dye molecules anchored on the surface of the UCNPs serve as an antenna which can broadly and strongly harvest NIR light. The Nd3+ facilitates the energy transfer and photon upconversion of the lanthanide activator at a biocompatible excitation wavelength (around 800 nm) with a significant increase in penetration ability and minimizes the overheating problem associated with conventional 980 nm excitation. The quenching-shield sandwich structure can greatly eliminate the deleterious cross-relaxation pathway between the activator and sensitizer. This approach combines the merits of the use of Nd3+ as a sensitizer, a quenching-shield sandwich structure and the "antenna" effect, leading to a tremendous enhancement of UCL under excitation at 808 nm. These well-designed UCNPs excited at 808 nm with improved optical performances will outperform conventional UCNPs excited at 980 nm and play an important role in the development of luminescent probes for future biological and medical applications. PMID- 29182692 TI - Novel chloride-centered Ag18 clusters featuring a cuboctahedral Ag12 skeleton. AB - Two novel chloride-centered Ag18 clusters with the same framework but different supporting phosphines are synthesized by the reaction of PhC[triple bond, length as m-dash]CAg, AgSbF6, PPh3 (or P(p-Tol)3), and NaBH4 in CH2Cl2, followed by the addition of PhC[triple bond, length as m-dash]CH and NEt3. The inner twelve Ag atoms of these two clusters are arranged in a rare cuboctahedral structure, which can be rationalized by considering a ligand effect. Through careful analysis, we find that the central chloride arises from a generally ignored but nonetheless existing reaction between CH2Cl2 and NEt3, which is well recognized as the Menshutkin reaction. This research provides insights into the dependence of the cluster structure on the nature of the ligand and into the cluster formation mechanism of the Menshutkin reaction. PMID- 29182693 TI - H2O2 induced formation of graded composition sodium-doped tin dioxide and template-free synthesis of yolk-shell SnO2 particles and their sensing application. AB - Sodium peroxostannate nanoparticles with graded composition were produced from aqueous hydrogen peroxide-sodium hydroxostannate solution. The uniform particles were converted to composition graded sodium stannate by mild thermal treatment for peroxide decomposition and yielded yolk-shell tin dioxide particles by dilute acid treatment. The mechanism of formation of the graded sodium concentration is explained in view of the solubility of peroxostannate in H2O2-H2O solution and based on 119Sn NMR, XRD, dynamic light scattering (DLS) and electron microscopy studies. Initial studies illuminating sensitive hydrogen sensing by yolk-shell tin oxide particles are presented. PMID- 29182688 TI - Interferon-gamma release assay for the diagnosis of latent tuberculosis infection: A latent-class analysis. AB - BACKGROUND: Accurate diagnosis and subsequent treatment of latent tuberculosis infection (LTBI) is essential for TB elimination. However, the absence of a gold standard test for diagnosing LTBI makes assessment of the true prevalence of LTBI and the accuracy of diagnostic tests challenging. Bayesian latent class models can be used to make inferences about disease prevalence and the sensitivity and specificity of diagnostic tests using data on the concordance between tests. We performed the largest meta-analysis to date aiming to evaluate the performance of tuberculin skin test (TST) and interferon-gamma release assays (IGRAs) for LTBI diagnosis in various patient populations using Bayesian latent class modelling. METHODS: Systematic search of PubMeb, Embase and African Index Medicus was conducted without date and language restrictions on September 11, 2017 to identify studies that compared the performance of TST and IGRAs for LTBI diagnosis. Two IGRA methods were considered: QuantiFERON-TB Gold In Tube (QFT GIT) and T-SPOT.TB. Studies were included if they reported 2x2 agreement data between TST and QFT-GIT or T-SPOT.TB. A Bayesian latent class model was developed to estimate the sensitivity and specificity of TST and IGRAs in various populations, including immune-competent adults, immune-compromised adults and children. A TST cut-off value of 10 mm was used for immune-competent subjects and 5 mm for immune-compromised individuals. FINDINGS: A total of 157 studies were included in the analysis. In immune-competent adults, the sensitivity of TST and QFT-GIT were estimated to be 84% (95% credible interval [CrI] 82-85%) and 52% (50 53%), respectively. The specificity of QFT-GIT was 97% (96-97%) in non-BCG vaccinated and 93% (92-94%) in BCG-vaccinated immune-competent adults. The estimated figures for TST were 100% (99-100%) and 79% (76-82%), respectively. T SPOT.TB has comparable specificity (97% for both tests) and better sensitivity (68% versus 52%) than QFT-GIT in immune-competent adults. In immune-compromised adults, both TST and QFT-GIT display low sensitivity but high specificity. QFT GIT and TST are equally specific (98% for both tests) in non-BCG-vaccinated children; however, QFT-GIT is more specific than TST (98% versus 82%) in BCG vaccinated group. TST is more sensitive than QFT-GIT (82% versus 73%) in children. CONCLUSIONS: This study is the first to assess the utility of TST and IGRAs for LTBI diagnosis in different population groups using all available data with Bayesian latent class modelling. Our results challenge the current beliefs about the performance of LTBI screening tests, and have important implications for LTBI screening policy and practice. We estimated that the performance of IGRAs is not as reliable as previously measured in the general population. However, IGRAs are not or minimally affected by BCG and should be the preferred tests in this setting. Adoption of IGRAs in settings where BCG is widely administered will allow for a more accurate identification and treatment of LTBI. PMID- 29182696 TI - The effect of the functional ionic group of the viologen derivative on visible light driven CO2 reduction to formic acid with the system consisting of water soluble zinc porphyrin and formate dehydrogenase. AB - The effect of the functional ionic group of 4,4'-bipyridinium salt derivatives (4,4'-BPs) as the electron carrier on the visible-light driven conversion of CO2 to formic acid with the system consisting of water-soluble zinc tetraphenylporphyrin tetrasulfonate (ZnTPPS) and formate dehydrogenase (FDH) in the presence of triethanolamine (TEOA) as an electron donor was investigated. 1,1'-Diaminoethyl- (DAV), 1-aminoethyl-1'-methyl- (AMV), 1-carboxymethyl-1' methyl- (CMV) and 1,1'-dicarboxymethyl-4,4'-bipyridinium salt (DCV) were prepared as the 4,4'-BPs with the functional ionic group. Irradiation of a CO2 saturated buffer solution containing TEOA, ZnTPPS, 4,4'-BP and FDH with visible light irradiation resulted in the production of formic acid. By using 4,4'-BPs with the cationic aminoethyl-group, DAV or AMV as an electron carrier, the effective visible-light driven formic acid production based on the CO2 reduction was observed compared to the 4,4'-BPs with the anionic carboxymethyl-group, CMV or DCV. The formic acid production rate with DAV was approximately 3.2 times higher than that of the system with DCV. PMID- 29182698 TI - Optical limiters with improved performance based on nanoconjugates of thiol substituted phthalocyanine with CdSe quantum dots and Ag nanoparticles. AB - Two alternative synthetic approaches affording a low-symmetry A3B-type phthalocyanine 1 bearing two [2'-(2''-mercaptoethoxy)ethoxy] anchoring substituents were developed. Due to the presence of thiol groups, this phthalocyanine could be conjugated with TOPO-capped (TOPO - trioctylphosphine) capped CdSe quantum dots (CdSe-QDs) or oleylamine capped silver nanoparticles (Ag NPs). The nonlinear optical behaviour of starting phthalocyanine, quantum dots, nanoparticles and their conjugates was studied by using an open aperture Z-scan technique, revealing that the grafting of 1 onto the nanomaterials resulted in a significant enhancement of the optical limiting of 1-Ag and 1-CdSe in comparison with the individual components. The conjugate 1-CdSe, being the first example of Pc-based thiol conjugated with quantum dots, revealed superior limiting characteristics with a limiting threshold below 0.18 J cm-2. PMID- 29182699 TI - Is the largest aqueous gold cluster a superatom complex? Electronic structure & optical response of the structurally determined Au146(p-MBA)57. AB - The new water-soluble gold cluster Au146(p-MBA)57, the structure of which has been recently determined at sub-atomic resolution by Vergara et al., is the largest aqueous gold cluster ever structurally determined and likewise the smallest cluster with a stacking fault. The core presents a twinned truncated octahedron, while additional peripheral gold atoms follow a C2 rotational symmetry. According to the usual counting rules of the superatom complex (SAC) model, the compound attains a number of 92 SAC electrons if the overall net charge is 3- (three additional electrons). As this is the number of electrons required for a major shell closing, the question arises of whether Au146(p-MBA)57 should be regarded as a superatom complex. Starting from the experimental coordinates we have analyzed the structure using density-functional theory. The optimized (relaxed) structure retains all the connectivity of the experimental coordinates, while removing much of its irregularities in interatomic distances, thereby enhancing the C2-symmetry feature. On analyzing the angular-momentum projected states, we show that, despite a small gap, the electronic structure does not exhibit SAC model character. In addition, optical absorption spectra are found to be relatively smooth compared to the example of the Au144(SR)60 cluster. The Au146(SR)57 does not derive its stability from SAC character; it cannot be considered as a superatom complex. PMID- 29182702 TI - Swings and Roundabouts in CNS Drug Biomarkers.

PMID- 29182706 TI - Clinical Effects of Tramiprosate in APOE4/4 Homozygous Patients with Mild Alzheimer's Disease Suggest Disease Modification Potential. AB - BACKGROUND: Alzheimer's Disease (AD) patients homozygous for the APOE4 allele (APOE4/4) have a distinct clinical and biological phenotype with high levels of beta amyloid (Abeta) pathology and toxic Abeta oligomers. Tramiprosate, an oral agent that inhibits Abeta monomer aggregation into toxic oligomers, was evaluated in two Phase 3 Mild to Moderate AD studies which did not show efficacy in the overall population. Re-analyses of these trials showed the most consistent clinical benefits in APOE4/4 patients. We analyzed efficacy in the APOE4/4 patients with Mild disease. OBJECTIVES: To determine the optimal stage of AD for future trials in APOE4/4 homozygotes. DESIGN: Two randomized, double-blind, placebo-controlled parallel-arm multi-center studies of 78-weeks duration. SETTING: Academic Alzheimer's disease centers, community-based memory clinics, and neuropsychiatric research sites. PARTICIPANTS: Participants included 2,025 AD patients with MMSE 16-26. Approximately 13-15% had APOE4/4 genotype (N= 147 and 110 per study), mean age 71.1 years, 56% females. Almost all were on stable symptomatic drugs. INTERVENTION: Randomized subjects received oral placebo, 100mg BID, or 150mg BID of tramiprosate. MEASUREMENTS: Co-primary outcomes were change from baseline in the ADAS-cog11 and CDR-SB. Disability assessment for dementia (DAD) was a secondary outcome. RESULTS: In APOE4/4 homozygotes receiving 150mg BID tramiprosate, efficacy in the traditional Mild AD patients (MMSE 20-26) was higher than the overall group (MMSE 16-26) and efficacy in the Mild patients (MMSE 22-26) was highest. Tramiprosate benefits compared to placebo on ADAS-cog, CDR-SB, and DAD were 125%, 81% and 71%, respectively (p<0.02). The Mild subgroup (MMSE 22-26) showed cognitive stabilization with no decline over 78 weeks, both ADAS-cog and DAD effects increased over time. Tramiprosate safety in APOE4/4 patients was favorable. Most common adverse events were nausea, vomiting, depression and decreased weight. CONCLUSIONS: The Mild subgroup of APOE4/4 AD patients (MMSE 22-26) showed larger benefits on the high dose of tramiprosate than the overall Mild and Moderate group. Consistent with its preclinical effects on Abeta oligomers, tramiprosate seemed to stabilize cognitive performance, supporting its disease modification potential. Confirmatory studies using ALZ 801, an improved pro-drug formulation of tramiprosate, will target APOE4/4 patients with Mild AD. PMID- 29182709 TI - The ROSAS Cohort: A Prospective, Longitudinal Study of Biomarkers for Alzheimer's Disease. Strategy, Methods and Initial Results. AB - OBJECTIVE: The aims of the Research Of biomarkers in Alzheimer's diseaSe (ROSAS) study were to determine the biofluid and imaging biomarkers permitting an early diagnosis of Alzheimer's disease and better characterisation of cognitive and behavioural course of the pathology. This paper outlines the overall strategy, methodology of the study, baseline characteristics of the population and first longitudinal results from the ROSAS cohort. METHODS: Longitudinal prospective monocentric observational study performed at the Alzheimer's disease Research centre in Toulouse. A total of 387 patients were studied and analyzed in 3 groups: 184 patients with dementia of Alzheimer's type, 96 patients with memory disorders without dementia (Mild Cognitive Impairment) and 107 patients without abnormal memory tests (control group), and were followed up during 4 years. Patient's sociodemographic characteristics, risk factors, medical conditions, previous and current medications, neuropsychological assessment and overall cognitive status were recorded. Blood and urine samples were collected at every year, Magnetic Resonance Imaging were performed at inclusion, after one year of follow-up and at the end of the study. RESULTS: At baseline, three different groups of the cohort differed interestingly in age, level of education, and in percentage of ApoEepsilon4 carriers whereas the history of cardiovascular and endocrine pathologies were similar among the groups. During the follow-up period (3-4 years) 42 mild cognitive impairment patients (43.8%) progressed to dementia, 7 controls progressed into mild cognitive impairment and 1 patient in the control group converted from mild cognitive impairment group to dementia of Alzheimer's type group. During the first year of follow up, the incidence of progression from mild cognitive impairment to dementia of Alzheimer's type was 12.7 per 100, during the second year 33.9 per 100 and 46.7 per 100 for the third year. CONCLUSION: This paper presents the baseline characteristics of the unique French prospective monocenter study in which the natural course of dementia of Alzheimer's type was evaluated. Future analysis of blood and urine samples collection from the ROSAS study will permit to identify possible biofluid biomarkers predicting the early stages of the dementia of Alzheimer's type and risk of progression from Mild Cognitive Impairment to Alzheimer's disease. PMID- 29182707 TI - Sex and Age Differences in the Association of Blood Pressure and Hypertension with Cognitive Function in the Elderly: The Rancho Bernardo Study. AB - OBJECTIVES: This study examines sex and age differences in associations of systolic and diastolic blood pressure (SBP, DBP), pulse pressure and hypertension with cognitive function in a community-dwelling population. DESIGN: Cross sectional study. SETTING: Research clinic visit in 1988-91. PARTICIPANTS: Participants were 693 men and 1022 women aged 50-97 Measurements: Blood pressure was measured and 12 cognitive function tests were administered. RESULTS: Average age was 73.8+/-9.9 in men and 73.2+/-9.3 in women; 62.6% of men and 63.4% of women were hypertensive (SBP>=140 mmHg, DBP>=90 mmHg, or antihypertensive medication use). Each 5-unit increment in SBP, DBP, or pulse pressure and categorical hypertension was associated with significantly increased odds of poor verbal fluency performance in men and poor Trails B performance in women, with strongest associations for hypertension (OR=1.97, CI:1.01,3.85 in men; OR=1.51, CI:1.01,2.26 in women). After age stratification, associations remained statistically significant in younger (<80 years ) but not older (>=80 years) participants. CONCLUSION: Blood pressure as a continuous or categorical variable was associated with poor performance on cognitive function tests, but domains varied by sex and associations were found only in those younger than 80 years. The absent associations in those aged 80 years and older could support the hypothesis that increased blood flow is required to maintain cerebral perfusion with advancing age, or could reflect a survivor effect. PMID- 29182710 TI - Objective Cognitive Impairment and Progression to Dementia in Women: The Prospective Epidemiological Risk Factor Study. AB - BACKGROUND: Identification of subjects with a progressive disease phenotype is an urgent need in the pharmaceutical industry where most of the recent clinical trials in Alzheimer's disease have failed. OBJECTIVES: The objective of this study was to identify subgroups of individuals with objective cognitive impairment (OCI), who were most likely to progress to dementia and to identify the risk factors associated with progression. DESIGN: Prospective cohort study. SETTING: Population-based. PARTICIPANTS: 5,380 elderly women from Denmark. MEASUREMENTS: The Short Blessed Test and a category fluency test with animal naming, was used to assess cognitive function, and to classify them into different groups of OCI. RESULTS: OCI was identified in 852 subjects at baseline. The risk of dementia was elevated for OCI subjects as compared to subjects with normal cognition (HR 1.46[1.19-1.79]). The courses of OCI were studied in a sub cohort who completed the cognitive assessment at both the baseline and the follow up visit (n = 1,933). Of these subjects 203 had OCI at baseline. The multi-domain subtypes of OCI were associated with progressive OCI. Subjects most likely to progress were older, physically inactive, had a higher level of total cholesterol (>6.5 mmol/L) and had a history of depression as compared to subjects with a non progressive course of OCI. CONCLUSIONS: In this cohort we identified a risk profile associated with progression from OCI in older women. The degree of impairment at baseline was an important predictor of conversion to dementia, additionally several modifiable risk factors were associated with progression. PMID- 29182708 TI - B-Vitamin Therapy for Kidney Transplant Recipients Lowers Homocysteine and Improves Selective Cognitive Outcomes in the Randomized FAVORIT Ancillary Cognitive Trial. AB - BACKGROUND: Objectives: Elevated plasma total homocysteine (tHcy) is associated with increased risk of cardiovascular disease, stroke and dementia. Results of clinical trials using B-vitamins to reduce the cognitive risks attributed to tHcy have been inconsistent. The high prevalence of both hyperhomocysteinemia and cognitive impairment among kidney transplant recipients makes them an important population in which to evaluate the effect of lowering homocysteine on cognitive function. We therefore evaluated whether B-vitamin therapy to lower tHcy would prevent cognitive-decline in a cohort of stable kidney transplant recipients. DESIGN: The study was a longitudinal ancillary of the FAVORIT trial, a randomized, placebo-controlled multi-site trial of high-dose B vitamins to reduce cardiovascular and cerebrovascular events in clinically stable kidney transplant recipients with elevated tHcy. PARTICIPANTS: 584 participants from 18 sites across North America. INTERVENTION: The intervention consisted of a daily multivitamin containing high-doses of folate (5.0 mg), vitamin B12 (1.0 mg) and vitamin B6 (50 mg). The placebo consisted of a daily multi-vitamin containing no folate and recommended daily allowances of vitamins B12 and B6 (0 mg folate; 2.0 ug vitamin B12; 1.4 mg vitamin B6). MEASUREMENTS: Annual neuropsychological assessment for up to 5 years (mean 3.3 years) using a standardized test battery. Efficacy was analyzed on an intention-to-treat basis using end-of-trial data. Subgroup analyses included stratification for baseline plasma B-vitamin and tHcy concentrations. RESULTS: At baseline, cognitive impairment was common with 61% of participants falling more than one standard deviation below published norms for at least one cognitive test. Fewer than 1% of participants had insufficient plasma folate < 5 ng/ml or vitamin B12 < 148 pmol/L. However, 44.6% had plasma B6 concentrations < 30 nmol/L. At follow-up, processing speed and memory scores were modestly but significantly better in the B-vitamin supplement group than in controls (p<=0.05). There was no interaction between baseline tHcy, B-vitamin status and treatment on the cognitive outcomes. CONCLUSIONS: High-dose B-vitamin supplementation provided modest cognitive benefit for kidney transplant recipients with elevated baseline tHcy. Since nearly all participants were folate and vitamin B12 sufficient at baseline, the potential cognitive benefits of folate and B12 supplementation in individuals with poor B-vitamin status remains to be determined. PMID- 29182711 TI - Evaluation of the Neuroprotective Potential of N-Acetylcysteine for Prevention and Treatment of Cognitive Aging and Dementia. AB - Alzheimer's disease is a progressive neurodegenerative disease for which there is no cure and only a few treatments providing little relief. Increased oxidative stress that is associated with aging is strongly implicated in the pathogenesis and progression of Alzheimer's disease. Studies have shown that levels of the endogenous antioxidant glutathione decline at an early stage of Alzheimer's disease with decreased levels correlating with worse cognitive functions. N acetylcysteine, a drug also widely available as a dietary supplement, is a precursor of L-cysteine, which in turn is a component of glutathione. Because cysteine availability is a limiting factor for glutathione synthesis, treatment with N-acetylcysteine may increase glutathione levels and thereby counter oxidative stress, promote redox -regulated cell signaling, and improve immune responses. In this review, we evaluate the existing literature and the potential of N-acetylcysteine in promoting cognitive health and alleviating cognitive decline associated with dementia. Discussion will also include possible mechanisms of action of N-acetylcysteine, its effects on aging biology, and safety of long-term use. Based on the available literature, a nutraceutical formulation containing N-acetylcysteine among other compounds has shown some pro cognitive benefits in Alzheimer's patients and older adults, but the evidence for N-acetylcysteine alone is less robust. Although N-acetylcysteine crosses the blood-brain-barrier, low bioavailability is an obstacle. One promising avenue of research may be to explore derivatives of N-acetylcysteine such as N acetylcysteine amide, which has been reported in preclinical studies to have higher permeability through cellular and mitochondrial membranes with increased central nervous system bioavailability compared to N-acetylcysteine. PMID- 29182712 TI - Sarcopenia Is Negatively Related to High Gravitational Impacts Achieved From Day to-day Physical Activity. AB - Background: Sarcopenia has been associated with reduced physical activity (PA). We aimed to determine if sarcopenia, and specific components of muscle size, function, and physical performance, are associated with high impacts achieved during habitual PA, as these are related to bone strength in community-dwelling older women. Methods: Participants were older women from the Cohort of Skeletal Health in Bristol and Avon. We defined sarcopenia using the EWGSOP criteria. Lower limb peak muscle power and force were assessed using Jumping Mechanography (JM). High vertical impacts were assessed by tri-axial accelerometry (at least 1.5g above gravity). Cross-sectional associations were analyzed by linear regression, adjusting for age, height and weight (or fat mass for models including appendicular lean mass index), comorbidities, smoking, alcohol, and Index of Multiple Deprivation. Results: Our analyses included 380 participants, with mean age 76.7 (SD 3.0) years; 242 (64%) also completed JM. In age-adjusted analysis, a negative relationship was observed between severity of sarcopenia and high, but not medium or low, impacts (p = .03 for trend). Regarding components of sarcopenia underlying this relationship, multivariable analyses revealed that gait speed (beta 1.47 [95% CI 1.14, 1.89], [beta-1] reflects the proportionate increase in high impacts per SD increase in exposure) and peak force (1.40 [1.07, 1.84]) were independently associated with high impacts. Conclusions: Older women with sarcopenia experienced fewer bone-strengthening high impacts than those with presarcopenia or without sarcopenia. To increase bone strengthening activity in older women, interventions need to improve both lower limb muscle force and walking speed. PMID- 29182713 TI - The direct effects of plant polyploidy on the legume-rhizobia mutualism. AB - Background: Polyploidy is known to significantly alter plant genomes, phenotypes and interactions with the abiotic environment, yet the impacts of polyploidy on plant-biotic interactions are less well known. A particularly important plant biotic interaction is the legume-rhizobia mutualism, in which rhizobia fix atmospheric nitrogen in exchange for carbon provided by legume hosts. This mutualism regulates nutrient cycles in natural ecosystems and provides nitrogen to agricultural environments. Despite the ecological, evolutionary and agricultural importance of plant polyploidy and the legume-rhizobia mutualism, it is not yet fully understood whether plant polyploidy directly alters mutualism traits or the consequences on plant growth. Scope: The aim was to propose a conceptual framework to understand how polyploidy might directly enhance the quantity and quality of rhizobial symbionts hosted by legume plants, resulting in increased host access to fixed nitrogen (N). Mechanistic hypotheses have been devised to examine how polyploidy can directly alter traits that impact the quantity (e.g. nodule number, nodule size, terminal bacteroid differentiation) and quality of symbionts (e.g. nodule environment, partner choice, host sanctions). To evaluate these hypotheses, an exhaustive review of studies testing the effects of plant polyploidy on the mutualism was conducted. In doing so, overall trends were synthesized, highlighting the limited understanding of the mechanisms that underlie variation in results achieved thus far, revealing striking gaps in knowledge and uncovering areas ripe for future research. Conclusions: Plant polyploidy can immediately alter nodule size, N fixation rate and the identity of rhizobial symbionts hosted by polyploid legumes, but many of the mechanistic hypotheses proposed here, such as bacteroid number and enhancements of the nodule environment, remain unexplored. Although current evidence supports a role of plant polyploidy in enhancing key aspects of the legume-rhizobia mutualism, the underlying mechanisms and effects on host benefit from the mutualism remain unresolved. PMID- 29182714 TI - Two critical brain networks for generation and combination of remote associations. AB - Recent functional imaging findings in humans indicate that creativity relies on spontaneous and controlled processes, possibly supported by the default mode and the fronto-parietal control networks, respectively. Here, we examined the ability to generate and combine remote semantic associations, in relation to creative abilities, in patients with focal frontal lesions. Voxel-based lesion-deficit mapping, disconnection-deficit mapping and network-based lesion-deficit approaches revealed critical prefrontal nodes and connections for distinct mechanisms related to creative cognition. Damage to the right medial prefrontal region, or its potential disrupting effect on the default mode network, affected the ability to generate remote ideas, likely by altering the organization of semantic associations. Damage to the left rostrolateral prefrontal region and its connections, or its potential disrupting effect on the left fronto-parietal control network, spared the ability to generate remote ideas but impaired the ability to appropriately combine remote ideas. Hence, the current findings suggest that damage to specific nodes within the default mode and fronto-parietal control networks led to a critical loss of verbal creative abilities by altering distinct cognitive mechanisms. PMID- 29182715 TI - Modulation of Rat 50-kHz Ultrasonic Vocalizations by Glucocorticoid Signaling: Possible Relevance to Reward and Motivation. AB - Background: Rats emit 50-kHz ultrasonic vocalizations (USVs) to communicate positive emotional states, and these USVs are increasingly being investigated in preclinical studies on reward and motivation. Although it is the activation of dopamine receptors that initiates the emission of 50-kHz USVs, non-dopaminergic mechanisms may modulate calling in the 50 kHz frequency band. To further elucidate these mechanisms, the present study investigated whether the pharmacological manipulation of glucocorticoid signaling influenced calling. Methods: Rats were administered corticosterone (1-5 mg/kg, s.c.), the glucocorticoid receptor antagonist mifepristone (40 or 100 mg/kg, s.c.), or the corticosterone synthesis inhibitor metyrapone (50 or 100 mg/kg, i.p.). The effects of these drugs on calling initiation and on calling recorded during nonaggressive social contacts or after the administration of amphetamine (0.25 or 1 mg/kg, i.p.) were then evaluated. Results: Corticosterone failed to initiate the emission of 50-kHz USVs and did not influence pro-social and amphetamine stimulated calling. Similarly, mifepristone and metyrapone did not initiate calling. However, metyrapone suppressed pro-social calling and calling stimulated by a moderate dose (1 mg/kg, i.p.) of amphetamine. Conversely, mifepristone attenuated calling stimulated by a low (0.25 mg/kg, i.p.), but not moderate (1 mg/kg, i.p.), dose of amphetamine and had no influence on pro-social calling. Conclusions: The present results demonstrate that glucocorticoid signaling modulates calling in the 50 kHz frequency band only in certain conditions and suggest that mechanisms different from the inhibition of corticosterone synthesis may participate in the suppression of calling by metyrapone.

PMID- 29182717 TI - Doxycycline in the management of sexually transmitted infections. AB - Doxycycline is a second-generation tetracycline, available worldwide for half a century. It is an inexpensive broad-spectrum antimicrobial agent largely used in the management of several bacterial infections, particularly involving intracellular pathogens, as well as in the treatment of acne or for the prophylaxis of malaria. Physicochemical characteristics of doxycycline (liposolubility) allow a high diffusion in the tissues and organs. It has high bioavailability and a long elimination half-life allowing oral administration of one or two daily doses. Over the last decade, the prevalence of bacterial sexually transmitted infections (STIs) (syphilis, chlamydiosis, gonorrhoea and Mycoplasma genitalium infections) has increased in most countries, mainly in MSM, many of whom are infected with HIV. In light of increasing prevalence of resistance towards first-line regimens of some STI agents and recently updated recommendations for STI management, doxycycline appears to be an attractive option compared with other available antibiotics for the treatment of some STIs due to its efficacy, good tolerability and oral administration. More recently, indications for doxycycline in STI prophylaxis have been evaluated. Considering the renewed interest of doxycycline in STI management, this review aims to update the pharmacology of, efficacy of, safety of and resistance to doxycycline in this context of use. PMID- 29182718 TI - A 3D Human Airway Model Enables Prediction of Respiratory Toxicity of Inhaled Drugs In Vitro. AB - Respiratory tract toxicity represents a significant cause of attrition of inhaled drug candidates targeting respiratory diseases. One of the key issues to allow early detection of respiratory toxicities is the lack of reliable and predictive in vitro systems. Here, the relevance and value of a physiologically relevant 3D human airway in vitro model (MucilAir) were explored by repeated administration of a set of compounds with (n = 8) or without (n = 7) respiratory toxicity following inhalation in vivo. Predictability for respiratory toxicity was evaluated by readout of cytotoxicity, barrier integrity, viability, morphology, ciliary beating frequency, mucociliary clearance and cytokine release. Interestingly, the data show that in vivo toxicity can be predicted in vitro by studying cell barrier integrity by transepithelial electrical resistance (TEER), and cell viability determined by the Resazurin method. Both read-outs had 88% sensitivity and 100% specificity, respectively, while the former was more accurate with receiver operating characteristic (ROC) AUC of 0.98 (p = .0018) compared with ROC AUC of 0.90 (p = .0092). The loss of cell barrier integrity could mainly, but not fully, be attributed to a loss of cell coverage in 6 out of 7 compounds with reduced TEER. Notably, these effects occurred only at 400 uM, at concentration levels significantly above primary target cell potency, suggesting that greater attention to high local lung concentrations should be taken into account in safety assessment of inhaled drugs. Thus, prediction of respiratory toxicity in 3D human airway in vitro models may result in improved animal welfare and reduced attrition in inhaled drug discovery projects.

PMID- 29182720 TI - Variation in xylem vulnerability to embolism in European beech from geographically marginal populations. AB - Climate change is expected to increase the frequency and intensity of droughts and heatwaves in Europe, leading to effects on forest growth and major forest dieback events due to hydraulic failure caused by xylem embolism. Inter-specific variability in embolism resistance has been studied in detail, but little is known about intra-specific variability, particularly in marginal populations. We evaluated 15 European beech populations, mostly from geographically marginal sites of the species distribution range, focusing particularly on populations from the dry southern margin. We found small, but significant differences in resistance to embolism between populations, with xylem pressures causing 50% loss of hydraulic conductivity ranging from -2.84 to -3.55 MPa. Significant phenotypic clines of increasing embolism resistance with increasing temperature and aridity were observed: the southernmost beech populations growing in a warmer drier climate and with lower habitat suitability have higher resistance to embolism than those from Northern Europe growing more favourable conditions. Previous studies have shown that there is little or no difference in embolism resistance between core populations, but our findings show that marginal populations have developed ways of protecting their xylem based on either evolution or plasticity. PMID- 29182721 TI - Molecular mimicry modulates plant host responses to pathogens. AB - Background: Pathogens often secrete molecules that mimic those present in the plant host. Recent studies indicate that some of these molecules mimic plant hormones required for development and immunity. Scope and Conclusion: This Viewpoint reviews the literature on microbial molecules produced by plant pathogens that functionally mimic molecules present in the plant host. This article includes examples from nematodes, bacteria and fungi with emphasis on RaxX, a microbial protein produced by the bacterial pathogen Xanthomonas oryzae pv. oryzae. RaxX mimics a plant peptide hormone, PSY (plant peptide containing sulphated tyrosine). The rice immune receptor XA21 detects sulphated RaxX but not the endogenous peptide PSY. Studies of the RaxX/XA21 system have provided insight into both host and pathogen biology and offered a framework for future work directed at understanding how XA21 and the PSY receptor(s) can be differentially activated by RaxX and endogenous PSY peptides. PMID- 29182723 TI - Extreme learning machines for reverse engineering of gene regulatory networks from expression time series. AB - Motivation: The reconstruction of gene regulatory networks (GRNs) from genes profiles has a growing interest in bioinformatics for understanding the complex regulatory mechanisms in cellular systems. GRNs explicitly represent the cause effect of regulation among a group of genes and its reconstruction is today a challenging computational problem. Several methods were proposed, but most of them require different input sources to provide an acceptable prediction. Thus, it is a great challenge to reconstruct a GRN only from temporal gene expression data. Results: Extreme Learning Machine (ELM) is a new supervised neural model that has gained interest in the last years because of its higher learning rate and better performance than existing supervised models in terms of predictive power. This work proposes a novel approach for GRNs reconstruction in which ELMs are used for modeling the relationships between gene expression time series. Artificial datasets generated with the well-known benchmark tool used in DREAM competitions were used. Real datasets were used for validation of this novel proposal with well-known GRNs underlying the time series. The impact of increasing the size of GRNs was analyzed in detail for the compared methods. The results obtained confirm the superiority of the ELM approach against very recent state-of-the-art methods in the same experimental conditions.

PMID- 29182722 TI - Cryptic gene pools in the Hypericum perforatum-H. maculatum complex: diploid persistence versus trapped polyploid melting. AB - Background and Aims: In Central Europe Hypericum perforatum and Hypericum maculatum show significant hybridization and introgression as a consequence of Pleistocene range fluctuations, and their gene pools are merging on higher ploidy levels. This paper discusses whether polyploid hybrid gene pools are trapped in the ecological climatic niche space of their diploid ancestors, and tests the idea of geographical parthenogenesis. Methods: DNA sequence information of nuclear ribosomal DNA and plastid loci, ploidy level estimates and ecological niche modelling are used to characterize the various diploid and polyploid gene pools and unravel spatio-temporal patterns of gene flow among them. Key Results: On the diploid level, the three gene pools are clearly distinct between and within species of H. perforatum (two gene pools) and H. maculatum, and their divergence dates back to the first half of the Pleistocene. All polyploids in Central Europe show high levels of past and contemporary gene flow between all three gene pools. The correlation of genetic and geographical distances breaks down if the latter is larger than 250 km, indicating recent and ongoing gene flow. The two species are ecologically differentiated, but in particular hybrids among all three gene pools do not show significant niche differences compared to their parental gene pools, except for some combinations with H. maculatum. Conclusions: Inter- and intraspecific gene flow between inter- and intra-species gene pools is limited on the diploid level, and the geographical distribution of the diploids largely reflects Pleistocene evolutionary history. Secondary contact promoted hybridization and introgression on the polyploid level, enabling offspring to escape the diploid gene pools. However, the hybrid polyploids do not show significant niche differences compared to their diploid progenitors. It is concluded that the observed absence of niche divergence has precluded further differentiation and geographical partitioning of new polyploid lineages being effectively separated from the parental lines. The predominantly apomictic reproducing polyploids are trapped in the polyploid gene pool and the ecological climatic niche space of their diploid ancestors. PMID- 29182724 TI - Worsening Anxiety, Irritability, Insomnia, or Panic Predicts Poorer Antidepressant Treatment Outcomes: Clinical Utility and Validation of the Concise Associated Symptom Tracking (CAST) Scale. AB - Background: We report on the psychometric properties of the 16-item Concise Associated Symptom Tracking Scale self-report scale and its clinical utility. Methods: The 5-domain (irritability, anxiety, mania, insomnia, and panic) structure of Concise Associated Symptom Tracking Scale was validated with confirmatory factor analysis in Combining Medications to Enhance Depression Outcomes trial participants at baseline (n=664). Correlations with other clinical measures were used for convergent and divergent validity. In participants with at least one postbaseline visit (n=630), worsening in each Concise Associated Symptom Tracking Scale domain was defined as >=1.28 SD increase from baseline for each visit (weeks 1, 2, 4, and 6) only. Worsening in any domain (except mania) was defined as overall worsening. Association of domain-specific and overall worsening with remission was tested with logistic regression analyses. Results: The 5-domain structure had adequate model fit on confirmatory factor analysis (GFI=0.93, CFI=0.89, and RMSEA=0.07). Scores on anxiety, panic, insomnia, and mania significantly correlated with Hamilton Rating Scale for Depression anxiety subscale (rs=0.27), Psychiatric Diagnostic Screening Questionnaire-panic scale (rs=0.35), sum of 3 Quick Inventory of Depressive Symptomatology Self-Report insomnia items (rs=0.55), and Altman Self-Rating Mania scale (rs=0.41), respectively. From baseline to week 6, 5.2%, 7.5%, 47.6%, 15.6%, 6.2%, and 27.6% participants (n=630) experienced irritability, anxiety, mania, insomnia, panic, and overall worsening, respectively. Participants with overall worsening were less likely to remit (31.6%) than those without any worsening (43.9%; odds ratio=0.53, 95% CI=0.36, 0.78). Conclusion: The 16-item Concise Associated Symptom Tracking Scale self-report has acceptable psychometric properties. Clinically significant worsening of irritability, anxiety, insomnia, or panic with antidepressant treatment is associated with poorer outcomes. PMID- 29182726 TI - The association between income and life expectancy revisited: deindustrialization, incarceration and the widening health gap. AB - Background: The health gap between the top and the bottom of the income distribution is widening rapidly in the USA, but the lifespan of America's poor depends substantially on where they live. We ask whether two major developments in American society, deindustrialization and incarceration, can explain variation among states in life expectancy of those in the lowest income quartile. Methods: Life expectancy estimates at age 40 of those in the bottom income quartile were used to fit panel data models examining the relationship with deindustrialization and incarceration between 2001 and 2014 for all US states. Results: A one standard deviation (s.d.) increase in deindustrialization (mean = 11.2, s.d. = 3.5) reduces life expectancy for the poor by 0.255 years [95% confidence interval (CI): 0.090-0.419] and each additional prisoner per 1000 residents (mean = 4.0, s.d. = 1.5) is associated with a loss of 0.468 years (95% CI: 0.213-0.723). Our predictors explain over 20% of the state-level variation in life expectancy among the poor and virtually the entire increase in the life expectancy gap between the top and the bottom income quartiles since the turn of the century. Conclusions: In the USA between 2001 and 2014, deindustrialization and incarceration subtracted roughly 2.5 years from the lifespan of the poor, pointing to their role as major health determinants. Future research must remain conscious of the upstream determinants and the political economy of public health. If public policy responses to growing health inequalities are to be effective, they must consider strengthening industrial policy and ending hyper-incarceration. PMID- 29182725 TI - Genomic epidemiology and antimicrobial resistance of Neisseria gonorrhoeae in New Zealand. AB - Background: Antimicrobial-resistant Neisseria gonorrhoeae is a major threat to public health. No studies to date have examined the genomic epidemiology of gonorrhoea in the Western Pacific Region, where the incidence of gonorrhoea is particularly high. Methods: A population-level study of N. gonorrhoeae in New Zealand (October 2014 to May 2015). Comprehensive susceptibility testing and WGS data were obtained for 398 isolates. Relatedness was inferred using phylogenetic trees, and pairwise core SNPs. Mutations and genes known to be associated with resistance were identified, and correlated with phenotype. Results: Eleven clusters were identified. In six of these clusters, >25% of isolates were from females, while in eight of them, >15% of isolates were from females. Drug resistance was common; 98%, 32% and 68% of isolates were non-susceptible to penicillin, ciprofloxacin and tetracycline, respectively. Elevated MICs to extended-spectrum cephalosporins (ESCs) were observed in 3.5% of isolates (cefixime MICs >= 0.12 mg/L, ceftriaxone MICs >= 0.06 mg/L). Only nine isolates had penA XXXIV genotypes, three of which had decreased susceptibility to ESCs (MIC = 0.12 mg/L). Azithromycin non-susceptibility was identified in 43 isolates (10.8%); two of these isolates had 23S mutations (C2611T, 4/4 alleles), while all had mutations in mtrR or its promoter. Conclusions: The high proportion of females in clusters suggests transmission is not exclusively among MSM in New Zealand; re-assessment of risk factors for transmission may be warranted in this context. As elevated MICs of ESCs and/or azithromycin were found in closely related strains, targeted public health interventions to halt transmission are urgently needed. PMID- 29182727 TI - An Ambulatory Polysomnography Study of the Post-traumatic Nightmares of Post traumatic Stress Disorder. AB - Study Objectives: This study used ambulatory polysomnography (PSG) to investigate post-traumatic nightmares of post-traumatic stress disorder (PTSD). The key research question was whether post-traumatic nightmares occur in both rapid eye movement (REM) and non-REM sleep, and if so, whether nightmares in each sleep stage differed in content, phenomenology, and heart rate response. Underlying sleep disorders were investigated in an exploratory way. Methods: Thirty-five treatment-seeking veterans, current serving military members, and emergency service personnel undertook full PSG using the Compumedics (Melbourne, Australia) SomtePSG V1 system, during an inpatient psychiatric admission. The PSG recording included an event button to be pressed when a nightmare occurred, allowing us to determine the stage of sleep, changes in heart rate, and associated sleep events. The content and phenomenological features of participants' nightmares were recorded. Results: Of the 35 participants, 29 reported a nightmare during their sleep study, but only 21 pressed the event button and could recall the content of one or more nightmare. This yielded sleep and nightmare data for 24 nightmares. Of the 24, 10 nightmares arose from REM sleep and 14 from non-REM (stages N1 and N2). Seven were accurate trauma replays and 17 were non-replay or a mixture of replay and non-replay. Most nightmares were associated with respiratory or leg movement events and increase in heart rate on awakening. Conclusions: Post traumatic nightmares of PTSD occur in both REM and non-REM sleep and are commonly associated with other sleep disturbances. These findings have important treatment implications. PMID- 29182728 TI - An evaluation of the impact of aloe vera and licorice extracts on the course of experimental pigeon paramyxovirus type 1 infection in pigeons. AB - The progressive decrease in the efficiency of synthetic drugs has prompted research into phytogenic feed additives with potentially immunomodulatory and anti-infective properties. Complex diseases with a mixed etiology, including viral, pose a growing problem in domestic pigeons. The aim of this study was to determine the effectiveness of various doses of aloe vera and licorice extracts on the course of experimental PPMV-1 infection in pigeons. The experiment was performed on pigeons divided into 5 groups, including one control group and 4 experimental groups, which were orally administered aloe vera or licorice extracts at 300 or 500 mg/kg BW for 7 d after experimental inoculation with PPMV 1. On d 4, 7, and 14 after inoculation, cloacal swabs and samples of organs were collected from 4 birds in each group. The samples were analyzed to determine the copy number of PPMV-1 RNA by TaqMan qPCR. The results indicate that licorice and aloe vera extracts inhibited PPMV-1 replication by decreasing viral RNA copy numbers in the examined organs. The most inhibitory effect was observed in pigeons receiving aloe vera extract at 300 mg/kg BW, for which PPMV-1 RNA copy numbers were approximately 7-fold lower (brain), 9-fold lower (kidneys), and 14 fold lower (liver) than in the control group. The results of this study point to the potentially antiviral effects of aloe vera and licorice extracts in pigeons infected with PPMV-1. To the best of our knowledge, this is the first study to investigate the antiviral properties of aloe vera and licorice extracts in domestic pigeons. PMID- 29182729 TI - Effects of Opioids Given to Facilitate Mechanical Ventilation on Sleep Apnea After Extubation in the Intensive Care Unit. AB - Study Objectives: Following extubation in the intensive care unit (ICU), upper airway (UA) edema and respiratory depressants may promote UA dysfunction. We tested the hypothesis that opioids increase the risk of sleep apnea early after extubation. Methods: Fifty-six ICU patients underwent polysomnography the night after extubation. Airflow limitation during wakefulness was identified using bedside spirometry. Correlation and ordinal regression analyses were used to quantify the effects of preextubation opioid dose on postextubation apnea hypopnea index (AHI) and severity of sleep apnea and whether or not inspiratory airway obstruction (ratio of maximum expiratory and inspiratory airflows at 50% of vital capacity [MEF50/MIF50] >= 1) during wakefulness predicts airway obstruction during sleep. Data were adjusted for age, gender, body mass index, as well as a generalized propensity score balanced for APACHE II, score for preoperative prediction of obstructive sleep apnea, duration of mechanical ventilation, chronic obstructive pulmonary disease, and a procedural severity score for morbidity. Results: Sleep apnea (AHI >= 5) was present in 40 (71%) of the 56 patients. Morphine equivalent dose given 24 hours prior extubation predicted obstructive respiratory events during sleep (r = 0.35, p = .01) and sleep apnea (odds ratio [OR] 1.17; 95% confidence interval [CI] 1.02-1.34). Signs of inspiratory UA obstruction (MEF50/MIF50 >= 1) assessed by bedside spirometry were strongly associated with sleep apnea (OR 5.93; 95% CI 1.16-30.33). Conclusions: High opioid dose given 24 hours prior to extubation increases the likelihood of postextubation sleep apnea in the ICU, particularly in patients with anatomical vulnerability following extubation. PMID- 29182730 TI - Genetic Variation in SLC8A1 Gene Involved in Blood Pressure Responses to Acute Salt Loading. AB - BACKGROUND: Salt sensitivity of blood pressure (SSBP) increases the risk of cardiovascular complications, and the heritability of SSBP is about 50% in Chinese population. However, studies identifying genes involved in BP responses to acute sodium loading and diuresis shrinkage are still limited. METHOD: A total of 342 essential hypertensives from Beijing were recruited in our study. A modified Sullivan's acute oral saline load and diuresis shrinkage test was conducted to each individual. Medical history and lifestyle risk factors were obtained by questionnaire. Generalized linear model was used to examine the associations of 29 single-nucleotide polymorphisms (SNPs) with SSBP and false discovery rate (FDR) was used to correct P values for multiple testing. RESULTS: In the process of acute sodium loading, after adjusting for age and 24-hour urinary sodium concentration, SNPs in CYP11B2, PRKG1, SLC8A1 genes were significantly associated with systolic BP (SBP) rising in the additive and recessive model; SNPs in CYP4A11, PRKG1, SLC8A1, and ADRB2 genes were significantly associated with diastolic BP (DBP) rising. In the process of diuresis shrinkage, SNPs of CLCNKA, eNOS, PRKG1 gene were associated with SBP and DBP decreasing. After FDR correction, rs434082 in SLC8A1 gene was still significantly associated with blood pressure rising during salt load. In the additive model, A allele increased DBP of 2.8 mm Hg (FDR_q = 0.029) and MAP of 3.1 mm Hg (FDR_q = 0.029) after adjusting for age and 24-hour urinary sodium concentration. CONCLUSION: SLC8A1 gene may contribute to BP change in the process of acute sodium loading in a Han Chinese population. PMID- 29182731 TI - The Association Between Serum Activin A Levels and Hypertension in the Elderly: A Cross-Sectional Analysis From I-Lan Longitudinal Aging Study. AB - BACKGROUND: Hypertension is an important risk factor for cardiovascular disease. Activin A, a member of the transforming growth factor-beta cytokine family, has been shown to regulate blood pressure through the renin-angiotensin system. However, the relationship between activin A and blood pressure remains uncertain. The objective of this study was to determine whether serum activin A levels are associated with blood pressure. METHOD: A total of 470 participants of I-Lan longitudinal Aging Study (ILAS) were eligible for this study. Serum levels of activin A were assessed by enzyme-linked immunosorbent assay. Cross-sectional analyses were performed, including comparisons of demographic characteristics, hypertensive status, and activin A levels. RESULTS: Among the study participants (50% men, mean age, 69 years), 236 (50.2%) were hypertensive and 234 (49.8%) were normotensive. Hypertensive patients had significantly higher serum activin A levels than normotensives (normotensive vs. hypertensive: 507 +/- 169 vs. 554 +/- 176 pg/ml, mean +/- SD, P < 0.001). All subjects were divided into 3 tertiles on the basis of serum activin A levels. Increasing tertiles of activin A were associated with higher systolic blood pressure (SBP), diastolic blood pressure and pulse pressure (PP) (all P < 0.001). After adjusting for all the potential confounding factors, serum activin A concentration was still significantly associated with SBP (P = 0.02) and PP (P = 0.03). CONCLUSIONS: Serum activin A level was associated with SBP and PP. Further studies are required to assess their causal relationship and the clinical relevance. PMID- 29182732 TI - A National Survey of Assertive Outreach Treatment Services for People Who Frequently Attend Hospital due to Alcohol-Related Reasons in England. AB - Aims: To characterize England's alcohol assertive outreach treatment (AAOT) services for people who frequently attend hospital due to alcohol-related reasons according to their concordance with six core AAOT components. Methods: A cross sectional national survey using structured telephone interviews with health professionals examining 6 essential AAOT components. High-level AAOT services were those that delivered 5 or more components, mid-level 3 to 4 components, low level AAOT services 2 or less. Results: The analysis included 37 services that were classified according to their concordance with the 6 AAOT components. Six were identified as high-level AAOT services, 13 as mid-level AAOT services and 18 as low-level services. Extended support covering housing, mental and physical health over and above alcohol consumption was the most commonly delivered AAOT component provided. Having a multidisciplinary team was the least observed component, delivered in 33% high-level AAOT services and in 15% mid-level AAOT services. None of the low-level AAOT services had a multidisciplinary team. Conclusions: Access to AAOT services developed to support high-cost and high needs frequent hospital attenders varies across the nation. Further research, service evaluation and AAOT implementation should focus on essential AAOT components rather than self-defined labels of AAOT. Short summary: The study investigated alcohol assertive outreach treatment (AAOT) services in England. The study found variability in service provision across AAOT services when measured against six essential AAOT components. Improvement of AAOT in England's hospitals should focus on the implementation of essential AAOT components.

PMID- 29182734 TI - Quality of life measured with EuroQol-five dimensions questionnaire predicts long term mortality, response, and reverse remodelling in cardiac resynchronization therapy patients. AB - Aims: There are previous studies on quality of life (QoL) in cardiac resynchronization therapy (CRT) patients; however, there are no data with the short EuroQol-five dimensions (EQ-5D) questionnaire predicting outcomes. We aimed to assess the predictive role of baseline QoL and QoL change at 6 months after CRT with EQ-5D on 5-year mortality and response. Methods and results: In our prospective follow-up study, 130 heart failure (HF) patients undergoing CRT were enrolled. Clinical evaluation, echocardiography, and EQ-5D were performed at baseline and at 6 months of follow-up, continued to 5 years. Primary endpoint was all-cause mortality at 5 years. Secondary endpoints were (i) clinical response with at least one class improvement in New York Heart Association without HF hospitalization and (ii) reverse remodelling with 15% reduction in left ventricular end-systolic volume at 6 months. Fifty-four (41.5%) patients died during 5 years, 85 (65.3%) clinical responders were identified, and 63 patients (48.5%) had reverse remodelling. Baseline issues with mobility were associated with lower response [odds ratio (OR) 0.36, 95% confidence interval (CI) 0.16 0.84; P = 0.018]. Lack of reverse remodelling correlated with self-care issues at baseline (OR 0.10, 95% CI 0.01-0.94; P = 0.04). Furthermore, self-care difficulties [hazard ratio (HR) 2.39, 95% CI 1.17-4.86; P = 0.01) or more anxiety (HR 1.51, 95% CI 1.00-2.26; P = 0.04) predicted worse long-term survival. At 6 months, mobility (HR 3.95, 95% CI 1.89-8.20; P < 0.001), self-care (HR 7.69, 95% CI 2.23-25.9; P = 0.001), or >= 10% visual analogue scale (VAS) (HR 2.24, 95% CI 1.27-3.94; P = 0.005) improvement anticipated better survival at 5 years. Conclusion: EuroQol-five dimension is a simple method assessing QoL in CRT population. Mobility issues at baseline are associated with lower clinical response, whereas self-care issues predict lack of reverse remodelling. Problems with mobility or anxiety before CRT and persistent issues with mobility, self care, and VAS scale at 6 months predict adverse outcome. PMID- 29182735 TI - Never smokers with resected lung cancer: different demographics, similar survival. AB - OBJECTIVES: We sought to examine changes over time in the proportion of never smokers among surgical lung cancer patients and to determine whether smoking history affected survival. METHODS: We performed a retrospective review of a prospective database. Among never smokers and smokers, demographic and pathological data were compared. Disease-free survival (DFS) and cancer-specific survival (CSS) were analysed. Propensity matching was performed for further comparison of survival in a matched cohort. RESULTS: Among 3232 patients, we identified 718 never smokers (22%), 993 smokers with <30 pack history (31%) and 1521 smokers with >=30 pack history (47%). The proportion of never smokers increased over time, comprising 26.6% of the cohort after 2007 compared with 16.1% prior thereto (P <= 0.001). Never smokers were younger, more likely to be women and Asian, more frequently had adenocarcinoma and lower lobe tumours and were more likely to have pStage I disease. In pStage-matched cohorts, there were no differences in DFS or CSS. Similarly, in propensity-matched groups (498 patients each), there was no difference in 5-year DFS (66% vs 67%, P = 0.661) or in CSS (84% vs 81%, P = 0.350). On univariate analysis of the matched cohort, never smoking status had no effect on DFS (hazard ratio 1.05, P = 0.661) or CSS (hazard ratio 1.16, P = 0.350). CONCLUSIONS: The proportion of never smokers undergoing resections for lung cancer is increasing. Never smokers have distinct demographic patterns and tend to be younger women with adenocarcinoma. Despite these differences, stage and propensity-matched never smokers have the same survival as smokers and remain at equal risk for recurrence and death. PMID- 29182736 TI - Does septal thickness influence outcome of myectomy for hypertrophic obstructive cardiomyopathy? AB - OBJECTIVES: Patients with hypertrophic obstructive cardiomyopathy and basal septal thickness <18 mm are often considered unsuitable candidates for myectomy. Mitral valve (MV) replacement is frequently performed instead. We aimed to determine whether septal thickness affects outcomes and adequacy of myectomy. METHODS: Clinical and echocardiographic data were reviewed for 1486 consecutive adult patients with hypertrophic obstructive cardiomyopathy who underwent transaortic septal myectomy from January 2005 through December 2014. Comparisons between patients, grouped by septal thickness (<18 mm, n = 369; 18-21 mm, n = 612 and >21 mm, n = 505), were performed with the Kruskal-Wallis and the Pearson chi2 tests and semiparametric analysis of covariance. RESULTS: Median group ages were 57, 57 and 54 years (P = 0.007); men comprised 50.4%, 56.7% and 62.0%, respectively (P = 0.003). Intrinsic MV disease was present in 5.9%, 5.2% and 4.6%, respectively (P = 0.80). All patients underwent transaortic septal myectomy. Additional mitral procedures were performed in 7.6%, 7.8% and 8.1%, respectively (P = 0.90). Reasons for MV surgery included intrinsic MV disease (66.7%), residual mitral regurgitation (30.8%) and residual gradient (2.6%). All groups had postoperative gradient relief (median reduction: 51, 54 and 50 mmHg; P = 0.11). Ventricular septal defect occurred in 4 patients (0.3%), and risk did not differ by group (P = 0.24). CONCLUSIONS: Adequate relief of left ventricular outflow tract obstruction can be achieved via transaortic septal myectomy without concomitant MV procedures when septal thickness is < 18 mm, and the risk of ventricular septal defect is minimal. Concomitant MV repair/replacement should be reserved for patients with intrinsic MV disease or inadequate relief of mitral regurgitation/left ventricular outflow tract obstruction following adequate extended septal myectomy. PMID- 29182737 TI - Health-related knowledge, beliefs and self-efficacy in women with polycystic ovary syndrome. AB - STUDY QUESTION: Do health-related knowledge, beliefs and self-efficacy differ between women with and without polycystic ovary syndrome (PCOS)? SUMMARY ANSWER: Women with PCOS felt at greater risk for adverse health outcomes, yet believed a healthy lifestyle was less beneficial to prevent weight gain relative to a comparison group. WHAT IS KNOWN ALREADY: Diet and physical activity are often used to treat PCOS, but there are high attrition rates and less engagement in self-help methods. It is unclear whether there are unique psychosocial considerations in PCOS that should be incorporated into these interventions. STUDY DESIGN, SIZE, DURATION: This cross-sectional study enrolled 475 women with (N = 255) and without PCOS (N = 220). PARTICIPANTS/MATERIALS, SETTING, METHODS: Female participants were recruited through paper and web-based advertisements across the US (mean age: 28.1 +/- 5.4 years). Participants were either diagnosed with PCOS by a healthcare professional (PCOS group) or had self-reported regular menstrual cycles (comparison group). A reliable and valid online instrument about health-related knowledge, beliefs and self-efficacy was administered to these participants. MAIN RESULTS AND THE ROLE OF CHANCE: Most women with PCOS had a basic understanding of nutrition (96%), but had misconceptions about diagnostic criteria for PCOS (>=86%). PCOS was associated with greater perceived susceptibility for disease and weight gain and poorer perceived control over these health outcomes (all P < 0.05), in relation to the comparison group. Women with PCOS also perceived fewer benefits of healthy behaviors on weight gain (P = 0.03) with less than half of the PCOS group attempting to follow government diet recommendations (47%). There were no differences in the self-efficacy of dietary behaviors between groups. LIMITATIONS, REASONS FOR CAUTION: It is likely that participant self-selection occurred due to the nature of recruitment in this study and results may have limited generalizability since most participants identified as Caucasian. Additionally, it is unclear whether some results may be clinically meaningful due to small effect sizes. WIDER IMPLICATIONS OF THE FINDINGS: These findings support that behavioral interventions should incorporate the unique psychosocial considerations associated with PCOS to encourage patient participation in lifestyle interventions.

PMID- 29182741 TI - Off-label use of thoracic aortic endovascular stent grafts to simplify difficult resections and procedures in general thoracic surgery. AB - OBJECTIVES: Tumour infiltration, or gross infectious involvement of the thoracic aortic wall, poses a significant intraoperative risk for fatal bleeding and therefore could compromise adequate resection or efficient surgical management of pleural infection in a considerable amount of cases. We present 3 successful cases of off-label thoracic aortic endografting to safeguard thoracic aortic wall integrity. METHODS: After all patients received thoracic stent grafts through femoral access into the descending aorta, the first patient underwent a resection of a locally advanced squamous cell carcinoma of the left inferior lobe cT4cN0 1cM0 after neoadjuvant chemoradiation, which had infiltrated the descending aortic wall. The second case was video-assisted thoracoscopic bilateral pleural decortication for empyema with aortic ulcers of the distal thoracic aorta in a patient with pancreatic intrathoracic fistula in a necrotizing pancreatitis. The third patient was operated for a locally advanced squamous cell carcinoma of the left inferior lobe initial stage cT4 cN1-2 cM0 after neoadjuvant chemoradiation, which had broad contact to the descending aorta at the level of thoracic vertebrae 7 and 8 on a circumference of circa 180 degrees . Regional ethics committee approval according the Swiss Federal Human Research Act was obtained according to regulations. RESULTS: Preventive stent graft placement resulted in complication-free resection and significantly minimized the risk of fatal intraoperative bleeding. Patients were thus not exposed to complications associated with aortic cross-clamping, possible prosthetic replacement and extracorporeal circulation techniques. CONCLUSIONS: In carefully selected patient populations, the resection of locally advanced tumours or infectious processes involving the aortic wall can be facilitated by thoracic endovascular aortic repair prior to resection. PMID- 29182740 TI - Speciation Generates Mosaic Genomes in Kangaroos. AB - The iconic Australasian kangaroos and wallabies represent a successful marsupial radiation. However, the evolutionary relationship within the two genera, Macropus and Wallabia, is controversial: mitochondrial and nuclear genes, and morphological data have produced conflicting scenarios regarding the phylogenetic relationships, which in turn impact the classification and taxonomy. We sequenced and analyzed the genomes of 11 kangaroos to investigate the evolutionary cause of the observed phylogenetic conflict. A multilocus coalescent analysis using ~14,900 genome fragments, each 10 kb long, significantly resolved the species relationships between and among the sister-genera Macropus and Wallabia. The phylogenomic approach reconstructed the swamp wallaby (Wallabia) as nested inside Macropus, making this genus paraphyletic. However, the phylogenomic analyses indicate multiple conflicting phylogenetic signals in the swamp wallaby genome. This is interpreted as at least one introgression event between the ancestor of the genus Wallabia and a now extinct ghost lineage outside the genus Macropus. Additional phylogenetic signals must therefore be caused by incomplete lineage sorting and/or introgression, but available statistical methods cannot convincingly disentangle the two processes. In addition, the relationships inside the Macropus subgenus M. (Notamacropus) represent a hard polytomy. Thus, the relationships between tammar, red-necked, agile, and parma wallabies remain unresolvable even with whole-genome data. Even if most methods resolve bifurcating trees from genomic data, hard polytomies, incomplete lineage sorting, and introgression complicate the interpretation of the phylogeny and thus taxonomy.

AB - Background: Using data from a large internet-based survey of European men having sex with men (MSM), we assessed factors associated with HIV testing and reasons for dissatisfaction with HIV testing and counselling among Hungarian MSM. Methods: A total of 2052 Hungarian MSM provided evaluable data for the European MSM Internet Survey (EMIS) in 2010. chi2 tests and Poisson regression with a robust variance estimator were used to assess factors associated with HIV testing and dissatisfaction with HIV testing and counselling. Results: A total of 42.1% of MSM reported never being testing for HIV. Over one-half of men (54.1%) who reported condomless anal intercourse (CAI) in the prior 12 months with a person of unknown or sero-discordant HIV status reported no lifetime HIV testing. The factor most strongly associated with dissatisfaction with HIV testing and counselling was test site with increased dissatisfaction with inpatient hospital settings vs. community-based organizations. Both lack of HIV testing and dissatisfaction with testing were independently associated with MSM who reported that no one, or only a few people, knew they were attracted to men. Conclusions: Lack of HIV testing was strongly associated with CAI. MSM reported that community based organizations better supported confidentiality and were more respectful during HIV testing. PMID- 29182743 TI - A Roadmap to Implementing Antimicrobial Stewardship Principles in Long-term Care Facilities (LTCFs): Collaboration Between an Acute-Care Hospital and LTCFs. AB - Effective 28 November 2017, the Centers for Medicare & Medicaid Services (CMS) mandated long-term care facilities (LTCFs) to have antimicrobial stewardship programs (ASPs) in place. Although guidance exists for establishing ASPs in LTCFs, limited data exist on the "how." As comprehensive ASPs already exist in many acute-care hospitals (ACHs) and with the known "sharing of patients" between both settings, extending ACH ASP expertise to LTCFs will not only aid LTCFs in complying with the CMS mandate but will likely also facilitate in decreasing multidrug-resistant organisms and Clostridium difficile infection rates in patients at both organizations. Here, we provide a roadmap on how to implement ASPs in LTCFs, using examples from our own ACH's collaboration with local LTCFs to develop and sustain LTCF ASPs. We discuss critical elements to achieving successful LTCF ASPs, including the potential barriers and how to overcome them. PMID- 29182744 TI - The Value of the Middle Meningeal Artery in Cerebrovascular Bypass Surgery: An Anatomic Feasibility Study. AB - BACKGROUND: Over the past decade, there has been a revival and a renewed interest for cerebrovascular bypass procedures. The superficial temporal artery (STA) has its value as a reliable donor vessel; however, a possible role for the middle meningeal artery (MMA) as a donor artery is still unclear. OBJECTIVE: To assess the feasibility of using the MMA as a donor vessel in cerebrovascular surgery. METHODS: We performed cadaveric dissections on 12 fresh specimens (23 sides) after bilateral silicone injection into the internal and external carotid arteries. We compared the size, diameter, and possibility to perform a bypass to the middle cerebral artery for both the MMA and the STA. Measurements were done using an electrical caliper. Additional measurements of the MMA and STA were performed on 20 random angiograms. RESULTS: There was no statistically significant difference in diameter of the MMA at its ostium being 2.4 mm, compared to 2.7 mm for the STA ostium (t-test; P = .21). The MMA could be mobilized over 4.1 cm, whereas the STA over 8.3 cm. Finally, the mean diameter of the donor vessel at the site of the anastomosis was 1.6 mm versus 1.9 mm for MMA and STA, respectively (P = .0026). We were able to perform an MMA and middle cerebral artery anastomosis on 17 sides. CONCLUSION: These results suggest that the MMA is a potentially valuable donor vessel to be used in selected cases. The availability of a suitable MMA branch should be assessed preoperatively on the angiogram. PMID- 29182745 TI - Unmet need for primary prevention in individuals with hypertriglyceridaemia not eligible for statin therapy according to European Society of Cardiology/European Atherosclerosis Society guidelines: a contemporary population-based study. AB - Aims: To identify individuals at high risk of atherosclerotic cardiovascular disease (ASCVD), who are not definite statin eligible according to the 2016 European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) guidelines, based on high concentrations of plasma triglycerides. Methods and results: From the Copenhagen General Population Study (2003-2015) 58 547 individuals aged 40-65 and free of ASCVD, diabetes, and statin use at baseline were included. Of these, 14% were definite statin eligible, 7% were not eligible and had triglycerides >=3.0 mmol/L (264 mg/dL), and 79% were not statin eligible and had triglycerides <3.0 mmol/L (264 mg/dL). During 456 057 person-years of follow-up, 1770 individuals experienced a major adverse cardiovascular event (MACE) and 734 experienced a myocardial infarction (MI). The cumulative incidences of MACE at age 70 were 8.1% (95% confidence interval 7.3-8.9%) and 14.6% (12.6-16.8%) in statin non-eligible individuals with triglycerides <3.0 mmol/L (264 mg/dL) and >=3.0 mmol/L (264 mg/dL), and 16.5% (14.0-19.3%) in statin eligible individuals. Corresponding cumulative incidences of MI were 3.0% (2.7 3.3%), 7.8% (6.4-9.5%), and 7.1% (5.9-8.4%), respectively. The estimated 10-year risks of MACE were 2.8% (2.6-3.0%) and 5.7% (4.9-6.6%) in statin non-eligible individuals with triglycerides <3.0 mmol/L (264 mg/dL) and >=3.0 mmol/L (264 mg/dL), and 7.6% (6.9-8.3%) in statin eligible individuals; the median age in these three groups were 51, 51, and 60 years, respectively. Corresponding risks of MI were 1.0% (0.9-1.1%), 3.0% (2.4-3.7%), and 3.3% (2.8-3.7%), respectively. Conclusion: Statin non-eligible individuals with triglycerides >=3.0 mmol/L (264 mg/dL) had risk of ASCVD similar to statin eligible individuals, defined according to the 2016 ESC/EAS guidelines. This illustrates an unmet need for primary prevention, calling for expansion of guidelines on statin eligibility, and the potential for placebo-controlled randomized clinical trials in individuals with hypertriglyceridaemia. PMID- 29182746 TI - Experiences of Persons With Parkinson's Disease Engaged in Group Therapeutic Singing. AB - Background: Parkinson's disease (PD) is a progressive neurodegenerative disorder that leads to altered neural control of movement, including the control of voice, respiration, and swallowing. There is a prevalent need to provide therapy for voice, respiration, and swallowing difficulties because current pharmacological and surgical treatments do not effectively treat these impairments. Previous research has demonstrated that singing may be a treatment option to target voice, respiratory, and swallowing impairments, as well as quality of life. However, participants' perspectives related to reasons for enrolling and engaging in programs as well as evaluation of singing programs have been neglected. Objective: The purpose of this descriptive study was thus to solicit participants' views of their involvement in a group singing intervention (GSI) led by credentialed music therapists. Methods: Twenty persons with PD were interviewed 4 to 6 months after completing the singing intervention. Participants were asked about 1) why they chose to participate, 2) what were the beneficial and non-beneficial aspects of participating, and 3) how to improve overall design and delivery of the GSI. Results: Using content analysis procedures, we learned that participants regarded their involvement in the study as mutually beneficial, fun, and engaging. Participants appreciated the fellowship with other persons with PD and offered minimal constructive criticism. Conclusions: This study provided greater insight into how a therapeutic singing program may benefit participants and positively impact their lives.

AB - IDSA did not endorse the 2016 Surviving Sepsis Campaign Guidelines despite being represented in the working group that drafted the guidelines document. Leadership from the IDSA, the Surviving Sepsis Campaign Guidelines, and the Society of Critical Care Medicine had numerous amicable discussions primarily regarding the bolded, rated guidelines recommendations. Our societies had different perspectives, however, regarding the interpretation of the major studies that informed the guidelines' recommendations, thus leading us to different conclusions and different perspectives on the recommendations. IDSA consequently elected not to endorse the guidelines. IDSA nonetheless hopes to be able to continue collaborating with the Surviving Sepsis Campaign and the Society of Critical Care Medicine to resolve our differences and to develop further strategies together to prevent sepsis and septic shock as well as reduce death and disability from these conditions both nationally and globally. PMID- 29182748 TI - Phrenic nerve injury during right inferior pulmonary vein ablation with the second-generation cryoballoon: clinical, procedural, and anatomical characteristics. AB - Aims: There is still sparse information regarding phrenic nerve injury (PNI) during ablation of the right inferior pulmonary vein (RIPV) by means of the second-generation cryoballoon advance (CB-A). The aim of this study was to describe the procedural, anatomical, and clinical characteristics of patients who experienced PNI during the RIPV ablation. Methods and results: Consecutive patients who had undergone pulmonary vein isolation (PVI) using CB-A and suffered PNI during RIPV ablation were retrospectively included in our study. A cohort of patients who did not suffer any PNI was randomly included in a 1:3 ratio as a control group. The incidence of PNI during RIPV cryoapplication was 3.5%, (34 of 979 patients). There were no significant differences in clinical characteristics between patients with and without PNI. The prevalence of right common ostium (RCO) was significantly higher in patients with a PNI [4 patients (11.8%) vs. 1 patient (1.0%); P < 0.01]. A temperature drop velocity from the basal temperature to - 20 degrees C of 2.38 degrees C/s rendered a sensitivity of 82.4% and a specificity of 51.0% with a negative predictive value of 89.7%. Temperature drop velocity from basal to - 20 degrees C and the presence of an RCO were predictors of PNI in the multivariate analysis [odds ratio (OR) 7.27, 95% confidence interval (CI) 2.54-20.80; P < 0.01 and OR 18.41, 95%CI 1.87-181.23; P = 0.01, respectively). Conclusion: PNI during RIPV freeze might occur in around 3.5% of cases. The presence of an RCO and a fast temperature drop must prompt a careful monitoring of the phrenic nerve function during cryoapplications on the RIPV. PMID- 29182750 TI - Capsule Endoscopy Validation of the Magnetic Enterography Global Score in Patients with Established Crohn's Disease. AB - Background and Aims: Capsule endoscopy [CE] and magnetic resonance enterography [MRE] are prime modalities for evaluation of the small bowel in Crohn's disease [CD]. Detection of proximal small bowel [SB] inflammation in CD by MRE is challenging. Currently available quantitative MRE scores do not incorporate proximal SB data. The MRE global score [MEGS] was designed for quantitative evaluation of the entire digestive tract; its accuracy in the proximal SB has not previously been evaluated. This study compared the evaluation of the small bowel inflammation by MEGS and CE-derived quantitative score (the Lewis score[LS]). Methods: CD patients in stable clinical remission were prospectively recruited and underwent MRE and CE; faecal calprotectin [FC] levels were obtained. MEGS was calculated for each SB segment and the entire SB [SBMEGS]. SB inflammation on CE was quantified using LS. A cumulative Lewis score [C-LS] was calculated based on summation of three tertiles scores. Results: Fifty patients were included. There was a significant correlation of SBMEGS with LS and C-LS [r = 0.61 and 0.71, both p = 0.001]. The correlation with FC was stronger for MEGS than for LS or C-LS [r = 0.68 vs r = 0.46 vs r = 0.53, all p = 0.001]. The correlation between the proximal LS and MEGS was significant [r = 0.55, p = 0.001]; median MEGS was significantly different in patients, with LS values consistent with mucosal healing, mild and moderate-to-severe inflammation. Conclusions: MEGS provides accurate evaluation of the SB and strongly correlates with FC; the main advantage of MEGS is the accurate quantification of proximal SB inflammation unavailable for alternative MRE scores. PMID- 29182751 TI - Adverse childhood experiences and access and utilization of health care. AB - Background: Adverse childhood experiences (ACEs) have been associated with a variety of negative health outcomes. However, the association between ACEs and access and utilization of health care have been largely ignored. Methods: This study examined data from the 2011 Behavioral Risk Factor Surveillance System (N = 101 527). We conducted logistic regression analyses, with nine ACEs as independent variables, in relation to the odds of being insured, having a personal health care provider and receiving a physician checkup in the past year. Unadjusted and adjusted multivariable models were estimated. Results: After accounting for potential confounders, all ACEs were associated with lower odds of being currently insured and receiving a physician checkup in the past year. Physical abuse, emotional abuse and several measures of household dysfunction were associated with lower odds of having a personal provider. Conclusions: Our findings suggest potential pathways by which ACEs may impact health. Provision of health insurance and providing care in a trauma-informed manner should be considered for individuals with a history of ACEs. PMID- 29182752 TI - The Quest for Welfare-Friendly Feeding of Broiler Breeders: Effects of Daily vs. 5:2 Feed Restriction Schedules. AB - Restricted feeding of broiler breeders is required for improved long-term health and welfare. Because feeding frustration and hunger are major welfare concerns during rearing, many suggestions have been made to decrease the negative feelings of hunger while maintaining suitable growth rates and reproductive health. Non daily ("skip-a-day") feeding schedules are commonly used around the world to increase portion sizes at meal times while restricting intake but these practices are prohibited in many countries due to welfare concerns on fasting days. We compared birds raised on a non-daily feeding schedule (2 non-consecutive fasting days per week, 5:2), previously suggested as a welfare-friendlier non-daily alternative, to birds raised on daily feed restriction. We found signs of increased physiological stress levels in 5:2 birds, including elevated heterophil to lymphocyte ratios (1.00 for 5:2 vs. 0.75 for daily fed at 12 weeks of age), increased adiposity (0.21% lean body weight [LBW] for 5:2 vs. 0.13% LBW for daily fed), and reduced muscle growth (pectoral muscle 5.94% LBW for 5:2 vs. 6.52% LBW for daily fed). At the same time, 5:2 birds showed signs of lower anxiety before feeding times (activity was reduced from 10.30 in daily fed to 4.85) which may be a result of the lower feed competition associated with larger portion sizes. Although we found no difference in latency to first head movement in tonic immobility between the treatments (136.5 s on average for both groups), 5:2 birds generally showed more interest in a novel object in the home pen which indicated increased risk taking and reduced fear while fasting. The 5:2 birds in this study showed no signs of learning the feeding schedule, and this unpredictability may also increase stress. Taken together, the effects of 5:2 vs. daily feed restriction on the welfare of broiler breeder pullets remain inconclusive and differ between feeding and fasting days. In addition to reducing stress by minimizing the number of fasting days, we suggest that a shift to more predictable schedules may help improve the welfare of broiler breeder pullets.

PMID- 29182754 TI - Pharmacogenetics-Based Warfarin Dosing in Patients With Cardiac Valve Replacement: The Effects of CYP2C9 and VKORC1 Gene Polymorphisms. AB - Many lines of evidence suggest that warfarin dosing variability is significantly associated with cytochrome P450 2C9 (CYP2C9) and vitamin K epoxide reductase complex subunit 1 (VKORC1) variant alleles. Therefore, we investigated the influence of CYP2C9*2 (430C/T), *3 (1075A/C) and VKORC1 (-1639G/A) polymorphisms on warfarin dose requirements in patients who underwent cardiac valve surgery during the postoperative period.A total of 100 patients with heart valve replacement who had a prescribed target international normalized ratio (INR) range of 2-3 were enrolled in the study. Genotyping of CYP2C9 and VKORC1 was carried out using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. The demographic and clinical data were collected using a precodified questionnaire and clinical examination and then were analyzed.Our findings revealed that the prevalence of CYP2C9 *2, *3 and VKORC1 -1639A alleles in patients were 10.5%, 39%, and 48%, respectively. We also found that patients with CYP2C9 *1 and VKORC1 -1639G alleles required the highest dosages of warfarin, while the carriers of CYP2C9 variant *2 and *3 alleles and VKORC1 -1639A required less warfarin. Univariate regression analysis showed that age and presence of CYP2C9 *2 allele significantly influenced the daily warfarin dose requirement. Our findings provide additional evidence to support the hypothesis that CYP2C9*2 (430C/T), *3 (1075A/C) and VKORC1 (-1639G/A) polymorphisms explain a considerable proportion of interindividual variability in warfarin dose. Therefore, testing for these variants might be helpful for adjusting patient warfarin dosage to an effective and safe level.

AB - Vaccination is an important tool in poultry health, but is itself a stressor often resulting in a reduction in feed intake, body weight gain, and nutrient digestibility. In other species, vaccination is associated with an immediate acute-phase response. As an important immune parameter, the circulating heterophil/lymphocyte (H/L) ratio is a well-recognized parameter of stress in poultry. In this study, the effects of a routinely used commercial poultry vaccine on the acute phase response (APR) and H/L ratios in specific pathogen free (SPF) layer chicks was examined to determine if post vaccination (PV) stress and an APR occur. A combined Newcastle disease and infectious bronchitis vaccine (Nobalis Ma5+Clone 30) was administered to SPF chicks by the intraocular route at age 7 d. Acute phase proteins (APP), alpha-1 acid glycoprotein (AGP) and serum amyloid A (SAA) were measured by enzyme-linked immunosorbent assays at d 0 (pre vaccination) and d 0.5, 1, 2, 3, 4, 5, 6, and 21 PV. Stress was determined in the chicks by measurement of the H/L ratio. The immune response to the vaccine was estimated by measurement of the antibody (IgY) response to the vaccine at d 21.The antibody titer was significantly (P < 0.05) higher in the vaccinated group at 21 d PV, confirming stimulation of the immune system. The H/L ratio was also significantly higher in the vaccinated group at 1 to 2 d (P < 0.01) and at 3 d (P < 0.05) PV. The concentration of SAA increased by 2.8-fold, from 63.7 MUg/mL in controls to 181 MUg/mL in the vaccinated group, (P < 0.05) at 1 d PV. AGP increased 1.6-fold at 2 d PV, (from 0.75 g/mL in the control group to 1.24 g/mL in the vaccinated group, P < 0.05).In conclusion an immediate but mild APR occurred in the chicks following intraocular vaccination, whereas the stress response as measured by H/L ratio seemed to be more specific and sensitive. Measurement of these biomarkers of the host response could be a tool in vaccine development. PMID- 29182757 TI - Super-response to cardiac resynchronization therapy may predict late phrenic nerve stimulation. AB - Aims : Changes in the anatomical relationship between left phrenic nerve and coronary veins may occur due to the reverse remodelling observed in super responders to cardiac resynchronization therapy (CRT) and might be the underlying mechanism in patients developing late-onset phrenic nerve stimulation (PNS) without evidence of lead dislodgement (LD). In this study, we sought to evaluate the role of super-response (SR) to CRT as a potential predictor of late-onset PNS. Methods and results: Consecutive patients implanted with a left ventricular (LV) lead in a single centre were retrospectively analysed. Phrenic nerve stimulation was classified as 'early' when it occurred within 3 months of implantation and 'late' for occurrences thereafter. 'Late' PNS was considered related to LD (LD-PNS) when LV threshold differed by > 1 V or impedance >250 Omega from baseline values or in case of radiological displacement. Cases not meeting the former criteria were classified as 'non-LD-PNS'. Super-response was defined as a decrease >=30% of the left ventricluar end-systolic volume at 1-year echocardiography. At 32 +/- 7 months follow-up, PNS occurred in 20 of 139 patients. Late non-LD-PNS incidence was significantly higher in the SR group (8/61; 13.1%) when compared with the non-SR (1/78; 1.3%) (P = 0.010). Super response remained the only predictor of non-LD-PNS at multivariate analysis (odds ratio: 11.62, 95% confidence interval 1.41-95.68, P = 0.023). Conclusion: Incidence of late non-LD-PNS is higher among SR to CRT, suggesting a potential role of the changes in the anatomical relationship between left phrenic nerve and coronary veins. PMID- 29182755 TI - Meta-analysis of DNA double-strand break response kinetics. AB - Most proteins involved in the DNA double-strand break response (DSBR) accumulate at the damage sites, where they perform functions related to damage signaling, chromatin remodeling and repair. Over the last two decades, studying the accumulation of many DSBR proteins provided information about their functionality and underlying mechanisms of action. However, comparison and systemic interpretation of these data is challenging due to their scattered nature and differing experimental approaches. Here, we extracted, analyzed and compared the available results describing accumulation of 79 DSBR proteins at sites of DNA damage, which can be further explored using Cumulus (http://www.dna repair.live/cumulus/)-the accompanying interactive online application. Despite large inter-study variability, our analysis revealed that the accumulation of most proteins starts immediately after damage induction, occurs in parallel and peaks within 15-20 min. Various DSBR pathways are characterized by distinct accumulation kinetics with major non-homologous end joining proteins being generally faster than those involved in homologous recombination, and signaling and chromatin remodeling factors accumulating with varying speeds. Our meta analysis provides, for the first time, comprehensive overview of the temporal organization of the DSBR in mammalian cells and could serve as a reference for future mechanistic studies of this complex process. PMID- 29182758 TI - MicroRNA-122 targets genes related to goose fatty liver. AB - MicroRNA-122 (miR-122), a completely conserved, liver-specific miRNA in vertebrates, is essential for the maintenance of liver homeostasis. This 22 nucleotide-length RNA regulates diverse functions such as cholesterol, glucose, and lipid metabolism as well as iron homeostasis and infection of hepatitis C virus (HCV). Landes goose, which has a good, fatty liver, has important significance for us in studying miR-122 function in goose fatty liver. In the current study, we identified miR-122 in goose liver and its expression pattern and target genes. We found that miR-122 was highly expressed in goose liver and its expression was down-regulated after overfeeding; some genes related to lipid metabolism, including prolyl 4-hydroxylase subunit alpha 1 (P4HA1); aldolase, fructose-bisphosphate B (ALDOB); and pyruvate kinase, muscle (PKM2), were predicted and validated as target genes of goose miR-122. After overexpression or inhibition of miR-122 in primary goose hepatocytes, the expression of ALDOB and PKM2 was changed, but not that of P4HA1, indicating miR-122 regulates ALDOB and PKM2 expression at the mRNA level. These findings suggest miR-122 play important roles in goose fatty liver by targeting some of the genes related to lipid metabolism. PMID- 29182759 TI - Long-term outcome after anomalous left coronary artery from the pulmonary artery repair: a 40-year single-centre experience. AB - OBJECTIVES: An anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly, often associated with severely impaired left ventricular (LV) contractility and functional mitral valve (MV) regurgitation. Current data suggest that earlier correction of ALCAPA may result in a more complete recovery of LV function. By analysing the results of a large single centre ALCAPA cohort, we sought to investigate whether these treatment paradigms remain valid. METHODS: A retrospective study was performed evaluating all patients undergoing repair of ALCAPA over a period of almost 40 years. All preoperative and postoperative echocardiographic reports were reviewed, focusing on the recovery of LV and MV function. RESULTS: The study cohort included 78 patients who underwent ALCAPA repair between 1977 and 2015, who were divided into 2 groups based on patient age at initial repair: Group A (n = 52, age <1 year) and Group B (n = 26, age >1 year). Following repair, systolic LV and MV function improved significantly (P < 0.01) in both groups. Patient age at the time of initial surgery had no significant influence on the improvement of LV function. Early mortality (within 30 days) was 10% (n = 8). No 30-day mortality was reported in the past 20 years. Survival at 20 years following ALCAPA repair was 86 +/- 4%. CONCLUSIONS: Following ALCAPA repair, LV function significantly improved, regardless of age at the time of repair. In addition, preoperative functional MV regurgitation decreased over time. Concomitant mitral valve surgery at the time of ALCAPA repair is required in patients with structural abnormalities of the MV. PMID- 29182760 TI - Expression Patterns of TNFalpha, MAdCAM1, and STAT3 in Intestinal and Skin Manifestations of Inflammatory Bowel Disease. AB - Background: Pathogenesis of cutaneous extraintestinal manifestations [EIM] in inflammatory bowel disease [IBD] remains elusive. Efficacy of anti-TNF agents suggests TNF-dependent mechanisms. The role of other biologics, such as anti integrins or JAK-inhibitors, is not yet clear. Methods: We performed immunohistochemistry for TNFalpha, NFkappaB, STAT1/STAT3, MAdCAM1, CD20/68, caspase 3/9, IFNgamma, and Hsp-27/70 on 240 intestinal [55 controls, 185 IBD] and 64 skin biopsies [11 controls, 18 erythema nodosum [EN], 13 pyoderma gangenosum [PG], 22 psoriasis]. A semiquantitative score [0-100%] was used for evaluation. Results: TNFalpha was upregulated in intestinal biopsies from active Crohn's disease [CD] vs controls [36.2 vs 12.1, p < 0.001], but not ulcerative colitis [UC: 17.9]. NFkappaB, however, was upregulated in intestinal biopsies from both active CD and UC [43.2 and 34.5 vs 21.8, p < 0.001 and p = 0.017, respectively]. TNFalpha and NFkappaB were overexpressed in skin biopsies from EN, PG, and psoriasis. No MAdCAM1 overexpression was seen in skin tissues, whereas it was upregulated in active UC vs controls [57.5 vs 35.4, p = 0.003]. STAT3 was overexpressed in the intestinal mucosa of active and non-active IBD, and a similar upregulation was seen in skin biopsies from EN [84.7 vs 22.3, p < 0.001] and PG [60.5 vs 22.3, p = 0.011], but not in psoriasis. Caspase 3 and CD68 overexpression in skin biopsies distinguished EN/PG from psoriasis and controls. Conclusions: Upregulation of TNFalpha/NFkappaB in EN and PG is compatible with the efficacy of anti-TNF in EIM management. Data on overexpressed STAT3, but not MAdCAM1, support a rationale for JAK-inhibitors in EN and PG, while questioning the role of vedolizumab. PMID- 29182761 TI - Sugar and Aldehyde Content in Flavored Electronic Cigarette Liquids. AB - Introduction: Sugars are major constituents and additives in traditional tobacco products, but little is known about their content or related toxins (formaldehyde, acetaldehyde, and acrolein) in electronic cigarette (e-cigarette) liquids. This study quantified levels of sugars and aldehydes in e-cigarette liquids across brands, flavors, and nicotine concentrations (n = 66). Methods: Unheated e-cigarette liquids were analyzed using liquid chromatography mass spectrometry and enzymatic test kits. Generalized linear models, Fisher's exact test, and Pearson's correlation coefficient assessed sugar, aldehyde, and nicotine concentration associations. Results: Glucose, fructose and sucrose levels exceeded the limits of quantification in 22%, 53% and 53% of the samples. Sucrose levels were significantly higher than glucose [chi2(1) = 85.9, p < .0001] and fructose [chi2(1) = 10.6, p = .001] levels. Formaldehyde, acetaldehyde, and acrolein levels exceeded the limits of quantification in 72%, 84%, and 75% of the samples. Acetaldehyde levels were significantly higher than formaldehyde [chi2(1) = 11.7, p = .0006] and acrolein [chi2(1) = 119.5, p < .0001] levels. Differences between nicotine-based and zero-nicotine labeled e-cigarette liquids were not statistically significant for sugars or aldehydes. We found significant correlations between formaldehyde and fructose (-0.22, p = .004) and sucrose ( 0.25, p = .002) and acrolein and fructose (-0.26, p = .0006) and sucrose (-0.21, p = .0006). There were no significant correlations between acetaldehyde and any of the sugars or any of the aldehydes and glucose. Conclusions: Sugars and related aldehydes were identified in unheated e-cigarette liquids and their composition may influence experimentation in naive users and their potential toxicity. Implications: The data can inform the regulation of specific flavor constituents in tobacco products as a strategy to protect young people from using e-cigarettes, while balancing FDA's interest in how these emerging products could potentially benefit adult smokers who are seeking to safely quit cigarette smoking. The data can also be used to educate consumers about ingredients in products that may contain nicotine and inform future FDA regulatory policies related to product standards and accurate and comprehensible labeling of e cigarette liquids. PMID- 29182762 TI - Cognitive Function Among Antiretroviral Treatment-Naive Individuals Infected With Human Immunodeficiency Virus Type 1 Subtype G Versus CRF02_AG in Nigeria. AB - Background: Human immunodeficiency virus type 1 (HIV-1) subtype has been shown to be associated with disease progression. We compared cognitive function between individuals infected with HIV-1 subtype G and CRF02_AG in Nigeria. Methods: For this cross-sectional study, samples were analyzed from 146 antiretroviral-naive participants. Genotypic analysis of plasma HIV RNA was performed by nested polymerase chain reaction of protease and reverse transcriptase genes, and sequences were aligned with curated HIV-1 subtype references. Cognitive status was determined using demographically adjusted T scores and global deficit score (GDS) obtained from a comprehensive neuropsychological test battery. Results: A total of 76 (52.1%) participants were infected with CRF02_AG, 48 (32.8%) with subtype G, and 22 (15.1%) with other HIV-1 strains. In a multivariable linear regression adjusting for plasma HIV RNA, CD4 count, and depression score, mean global T score was lower among subtype G-infected compared with CRF02_AG-infected participants (mean difference, -3.0 [95% confidence interval {CI}, -5.2, to -.7]; P = .011). Also, T scores were significantly lower among subtype G- than CRF02_AG infected participants for the speed of information processing, executive function, and verbal fluency ability domains. Adjusting for similar variables in a logistic regression, the odds of global cognitive impairment (GDS >=0.5) were 2.2 times higher among subtype G compared with CRF02_AG-infected participants (odds ratio, 2.2 [95% CI, .9-5.4]; P = .078). Conclusions: Cognitive performance was significantly worse among antiretroviral-naive individuals with HIV-1 subtype G vs CRF02_AG infection. Further studies are required to characterize the mechanistic basis for these differences. PMID- 29182763 TI - Salvage radiotherapy for second oligo-recurrence in patients with breast cancer. AB - A new concept designated 'oligo-recurrence (OR)' has been proposed, which indicates one to several distant metastases/recurrences in one or more organs, which can be treated with local therapy, after the primary site of the cancer has been controlled. The purpose of this study was to assess the efficacy and toxicity of salvage radiotherapy (RT) for the second OR of breast cancer. The second OR was defined as once-salvaged patients with OR who had a second failure that was also detected as the state of OR. Twenty-one patients with second OR were treated with salvage RT and were retrospectively analyzed. The sites of the second OR were locoregional recurrence in 7 patients and distant metastasis in 14 patients. Salvage RT was performed at a median total dose of 60 Gy. Nineteen (90%) patients had an objective response. The median overall survival and progression-free survival (PFS) times were 41 and 24 months after salvage RT for the second OR, respectively. The 3-year local (in-field) control (LC) rates were 93%. The toxicities were mild; acute toxicities >=Grade 3 were seen in one patient with Grade 3 dermatitis, and no late toxicity >=Grade 2 was observed. In conclusion, salvage RT for the second OR was able to achieve a better LC rate and longer PFS time without inducing severe toxicity, and therefore may be a potentially effective modality for inducing long-term survival in select patients. PMID- 29182764 TI - Balloon-expandable transapical transcatheter aortic valve implantation with or without predilation of the aortic valve: results of a multicentre registry. AB - OBJECTIVES: To assess safety and efficacy of transapical transcatheter aortic valve implantation (TA-TAVI) in the absence of predilation using balloon aortic valvuloplasty (BAV). Predilation of the stenosed valve using BAV is a routine step in TA-TAVI; however, evidence supporting its clinical value is lacking, and several studies have linked it with higher complication rates. METHODS: A prospective, two-armed, multicentre registry (EASE-IT TA) to gather data on patients undergoing TA-TAVI with or without BAV, using the Edwards SAPIEN 3 valve was designed. The primary evaluation criterion was a composite of all-cause mortality, non-fatal stroke, non-fatal myocardial infarction, acute kidney injury and pacemaker implantation [per Valve Academic Research Consortium-2 (VARC-2)] within 30 days after TAVI. RESULTS: A total of 198 subjects underwent TA-TAVI, 61 with and 137 without BAV. Patient characteristics were comparable at baseline (mean +/- SD: age 80.3 +/- 5.7 years; logistic EuroSCORE 20.2 +/- 12.6). Similar reductions in peak and mean transvalvular gradients were observed post procedurally. There was a significant reduction of fluoroscopy time without BAV (4.7 vs 7.9 min; P = 0.039) and significantly decreased odds of catecholamine administration (17.5% vs 32.8%; P = 0.017). A decreased odds of the primary evaluation criterion in patients without BAV after 30 days (adjusted odds ratio 0.71; 95% confidence interval 0.34-1.82) and the same composite end-point after 6 months (adjusted odds ratio 0.74; 95% confidence interval 0.37-1.47) were not significant even after multivariable adjustment. CONCLUSIONS: TA-TAVI without BAV appears to be at least equal to its conventional counterpart in terms of efficacy and may offer advantages in terms of safety. Thus, there appears to be little justification for maintaining the BAV step in TA-TAVI for many patients. PMID- 29182765 TI - qPCR-25 years old but still a matter of debate.

PMID- 29182769 TI - The Quality of Nonprey Food Affects Cannibalism, Intraguild Predation, and Hyperpredation in Two Species of Phytoseiid Mites. AB - Generalist arthropod predators not only prey on herbivores but also may engage in competitive interactions by attacking and consuming conspecifics (cannibalism) or other predators (intraguild predation [IGP] and hyperpredation). These types of interactions are quite common among predators used in biological control. Although there is evidence that nonprey food relaxes cannibalism and IGP, there is little information regarding the impact of the quality of the nonprey food. Herein, we examined how pollen of different nutritional quality (pine, narrow leaf cattail, or apple) impacted 1) the cannibalism by females of Euseius stipulatus (Athias-Henriot) (Acari: Phytoseiidae) on conspecific larvae, 2) the reciprocal predation between gravid females of E. stipulatus or Iphiseius degenerans (Berlese) (Acari: Phytoseiidae) and heterospecific larvae, and 3) the predation of E. stipulatus on the eggs of the aphid predator Aphidoletes aphidimyza (Rondani) (Diptera: Cecidomyiidae). E. stipulatus cannibalism was significantly reduced in the cattail pollen treatment, whereas in the pine pollen it did not significantly differ from control (no food). Predation between I. degenerans and E. stipulatus was significantly reduced in the cattail pollen treatment as compared to the control treatment. Finally, predation of E. stipulatus on A. aphidimyza eggs was significantly reduced when cattail or apple pollen was provided compared to the pine pollen or control treatments. These results suggest that cattail or apple pollen is suitable for mitigating negative interactions among generalist predatory mites used in biological control. PMID- 29182770 TI - Field Distribution and Density of Culicoides sonorensis (Diptera: Ceratopogonidae) Eggs in Dairy Wastewater Habitats. AB - Culicoides sonorensis Wirth and Jones (Diptera: Ceratopogonidae) is a key bluetongue virus vector in the United States. Immatures occur in mud near the edges of wastewater ponds and are understudied targets for control efforts. Eggs of C. sonorensis were collected in the morning from a dairy wastewater pond bank by taking 5-ml surface mud samples along four transects on each of six dates. Surface mud samples parallel to waterline (10-cm long, 1-cm wide, and 0.5-cm deep) were removed at 5-cm increments ranging from 15 cm below waterline up to 25 cm above waterline. Eggs were removed using MgSO4 flotation, held on moist filter paper, and scored for hatching over 3 d. Eggs hatching on days 2 and 3 were assumed to have been laid on the test night. Water levels were stable within a night according to time-lapse camera photos. Most samples from below the waterline had no eggs and were not analyzed statistically. Mean (+/-SE) sample moisture (25.8 +/- 2.1 at 5 cm above waterline and 19.8 +/- 2.6% at 25 cm above waterline) did not vary significantly by position above waterline. The highest density of viable eggs (21 eggs/5 ml), proportion of mud samples positive for viable eggs (75%), and proportion of eggs hatching (80%) were found 5 cm above waterline. Oviposition in the few hours after sunset is adaptive, allowing eggs to age, develop the serosal cuticle, and resist later desiccation. As a potential control method, reducing water levels after midnight would encourage young egg desiccation.

PMID- 29182772 TI - Identification of Ceratitis capitata (Diptera: Tephritidae) Sperm From Females in Traps: The Importance of the Ventral Receptacle. AB - The monitoring of a pest population often relies on the identification of individuals from traps. For area-wide programs utilizing the sterile insect technique, the further identification of the mated status of females found in traps is of utmost importance. For the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), this is usually verified through the assessment of sperm in the spermathecae. However, this can be misleading for species where there are other sperm storage organs such as the ventral receptacle. Here, we studied the relative importance of sperm storage in the ventral receptacle compared to the spermathecae for females from 5 to 18 d of age. Furthermore, we studied how sperm can be identified in the ventral receptacle or spermathecae after females were recovered from traps. We found no effect of female age on likelihood of sperm storage. Sperm could be identified in both sperm storage organs at 7 or 14 d after females had been placed in traps. We found that the ventral receptacle is a more reliable indicator of female mated status. Thus, we propose that if no sperm are found in the spermathecae, program managers should revise the ventral receptacle before assuming that females are not mated. This test may also be relevant to other pest tephritids that store even more sperm in the ventral receptacle than C. capitata. PMID- 29182773 TI - Mechanism of formation of a toroid around DNA by the mismatch sensor protein. AB - The DNA mismatch repair (MMR) pathway removes errors that appear during genome replication. MutS is the primary mismatch sensor and forms an asymmetric dimer that encircles DNA to bend it to scan for mismatches. The mechanism utilized to load DNA into the central tunnel was unknown and the origin of the force required to bend DNA was unclear. We show that, in absence of DNA, MutS forms a symmetric dimer wherein a gap exists between the monomers through which DNA can enter the central tunnel. The comparison with structures of MutS-DNA complexes suggests that the mismatch scanning monomer (Bm) will move by nearly 50 A to associate with the other monomer (Am). Consequently, the N-terminal domains of both monomers will press onto DNA to bend it. The proposed mechanism of toroid formation evinces that the force required to bend DNA arises primarily due to the movement of Bm and hence, the MutS dimer acts like a pair of pliers to bend DNA. We also shed light on the allosteric mechanism that influences the expulsion of adenosine triphosphate from Am on DNA binding. Overall, this study provides mechanistic insight regarding the primary event in MMR i.e. the assembly of the MutS-DNA complex.

PMID- 29182774 TI - Heterozygous SSBP1 start loss mutation co-segregates with hearing loss and the m.1555A>G mtDNA variant in a large multigenerational family. AB - The m.1555A>G mtDNA variant causes maternally inherited deafness, but the reasons for the highly variable clinical penetrance are not known. Exome sequencing identified a heterozygous start loss mutation in SSBP1, encoding the single stranded binding protein 1 (SSBP1), segregating with hearing loss in a multi generational family transmitting m.1555A>G, associated with mtDNA depletion and multiple deletions in skeletal muscle. The SSBP1 mutation reduced steady state SSBP1 levels leading to a perturbation of mtDNA metabolism, likely compounding the intra-mitochondrial translation defect due to m.1555A>G in a tissue-specific manner. This family demonstrates the importance of rare trans-acting genetic nuclear modifiers in the clinical expression of mtDNA disease. PMID- 29182776 TI - Crystal structure of an anti-CRISPR protein, AcrIIA1. AB - Clustered regularly interspaced short palindromic repeats (CRISPRs) and CRISPR associated (Cas) proteins provide bacteria with RNA-based adaptive immunity against phage infection. To counteract this defense mechanism, phages evolved anti-CRISPR (Acr) proteins that inactivate the CRISPR-Cas systems. AcrIIA1, encoded by Listeria monocytogenes prophages, is the most prevalent among the Acr proteins targeting type II-A CRISPR-Cas systems and has been used as a marker to identify other Acr proteins. Here, we report the crystal structure of AcrIIA1 and its RNA-binding affinity. AcrIIA1 forms a dimer with a novel two helical-domain architecture. The N-terminal domain of AcrIIA1 exhibits a helix-turn-helix motif similar to transcriptional factors. When overexpressed in Escherichia coli, AcrIIA1 associates with RNAs, suggesting that AcrIIA1 functions via nucleic acid recognition. Taken together, the unique structural and functional features of AcrIIA1 suggest its distinct mode of Acr activity, expanding the diversity of the inhibitory mechanisms employed by Acr proteins. PMID- 29182777 TI - Evaluation of a prognostic scoring system based on the systemic inflammatory and nutritional status of patients with locally advanced non-small-cell lung cancer treated with chemoradiotherapy. AB - Systemic inflammation and poor nutritional status have a negative effect on the outcomes of cancer. Here, we analyzed the effects of the pretreatment inflammatory and nutritional status on clinical outcomes of locally advanced non small-cell lung cancer (NSCLC) patients treated with chemoradiotherapy. We retrospectively reviewed 89 patients with locally advanced NSCLC treated with chemoradiotherapy between July 2006 and June 2013. Serum C-reactive protein (CRP) was assessed as an inflammatory marker, and serum albumin, body mass index (BMI) and skeletal mass index were assessed as nutritional status markers. The relationships between these markers and overall survival (OS) were assessed. The median OS was 24.6 months [95% confidence interval (CI): 19.4-39.3 months]. During follow-up, 58 patients (65%) had disease recurrence and 52 patients (58%) died. In multivariate Cox hazard analysis, CRP levels and BMI approached but did not achieve a significant association with OS (P = 0.062 and 0.094, respectively). Recursive partitioning analysis identified three prognostic groups based on hazard similarity (CRP-BMI scores): 0 = CRP < 0.3 mg/dl, 1 = CRP >= 0.3 mg/dl and BMI >= 18.5 kg/m2, and 2 = CRP >= 0.3 mg/dl and BMI < 18.5 kg/m2. The CRP-BMI score was significantly associated with OS (P = 0.023). Patients with scores of 0, 1 and 2 had median OS of 39.3, 24.5 and 14.5 months, respectively, and the scores also predicted the probability of receiving salvage treatment after recurrence. The CRP-BMI score is thus a simple and useful prognostic marker of clinical outcome for patients with locally advanced NSCLC treated with chemoradiotherapy. PMID- 29182778 TI - Jointly aligning a group of DNA reads improves accuracy of identifying large deletions. AB - Performing sequence alignment to identify structural variants, such as large deletions, from genome sequencing data is a fundamental task, but current methods are far from perfect. The current practice is to independently align each DNA read to a reference genome. We show that the propensity of genomic rearrangements to accumulate in repeat-rich regions imposes severe ambiguities in these alignments, and consequently on the variant calls-with current read lengths, this affects more than one third of known large deletions in the C. Venter genome. We present a method to jointly align reads to a genome, whereby alignment ambiguity of one read can be disambiguated by other reads. We show this leads to a significant improvement in the accuracy of identifying large deletions (>=20 bases), while imposing minimal computational overhead and maintaining an overall running time that is at par with current tools. A software implementation is available as an open-source Python program called JRA at https://bitbucket.org/jointreadalignment/jra-src. PMID- 29182779 TI - Phosphine Resistance in North American Field Populations of the Lesser Grain Borer, Rhyzopertha dominica (Coleoptera: Bostrichidae). AB - Phosphine is the most widely used fumigant for stored grain insect pests, and resistance to phosphine has evolved in several species worldwide. This study was designed to determine the presence of phosphine resistance in 34 populations of Rhyzopertha dominica (F.) collected from the United States and Canada. Adult R. dominica were sampled and subjected to a discriminatory dose toxicity assay of exposure to 20 ppm of phosphine for 20 h of exposure to distinguish a susceptible R. dominica adult by death from a resistant beetle that survives the treatment. All but two of the 34 geographic populations surveyed had some beetles that were resistant to phosphine, and the frequency of resistance varied from 97% in a population from Parlier, California to 0% in beetles from both Carnduff, Saskatchewan and Starbuck, Manitoba. Probit analyses of dose-mortality bioassays with beetles from a laboratory-susceptible strain and those from five of the populations sampled were used to calculate resistance ratio factors (RRs) based on the ratio of LC50 (estimate for the concentration to kill 50% of a test group) in the sampled population to the LC50 for the susceptible strain. The highest RR for the five resistant populations was nearly 596-fold in beetles from Belle Glade, Florida, whereas the lowest RR in that group was 9-fold in Wamego, Kansas. This study revealed that phosphine resistance in R. dominica is common across North America and some populations have levels of resistance that may pose challenges for continued use of phosphine for their management. PMID- 29182780 TI - Cold Hardiness of Overwintering Larvae of Sphenoptera sp. (Coleoptera: Buprestidae) in Western China. AB - An undetermined species of Sphenoptera sp. is an important pest of Artemisia ordosica Krasch, and recently, an outbreak of this insect has spread throughout Ningxia, Inner Mongolia, Shanxi, and other regions in western China. The cold hardiness of overwintering larvae of Sphenoptera sp. was determined by measuring their supercooling point (SCP) and their mortality at sub-zero temperatures. Additionally, quantitative changes in sugars and low molecular weight sugar alcohols in larvae were determined following exposure of larvae to low temperatures. Mean SCP of overwintering larvae (i.e., collected in January) was 30.2 +/- 0.60 degrees C. The mortality rate of larvae approached 100% at -30 degrees C, whereas mortality rates of larvae in the higher temperature treatments were generally less than 25%. Five sugars and sugar alcohols (i.e., glycerol, fructose, glucose, inositol, and trehalose) were detected in larvae. When larvae were exposed to low temperatures for 4 h, inositol, trehalose and total content was generally higher at the highest incubation temperature (-10 degrees C) than at lower incubation temperatures. Following a longer exposure (30 d), content of fructose, glucose, trehalose and total content generally increased with decreasing temperature down to -25 degrees C. Thus it appears that Sphenoptera sp. larvae are freeze avoidant, and their cold hardiness may be achieved by accumulation low molecular weight sugars and sugar alcohols. PMID- 29182782 TI - Abundance and Dynamics of Anopheles (Diptera: Culicidae) Larvae in a Malaria Endemic Area of Bangladesh. AB - Malaria is a major health burden in the border-belt areas of Bangladesh. There are recent data from adult mosquito collections that a number of vectors are involved in the transmission cycle. However, little information regarding the larval habitats of Anopheles mosquitoes are available in Bangladesh. To start filling this gap, a cross-sectional larval survey was conducted in Bandarban, Bangladesh from October 2011 to September 2012. Descriptive analysis, Poisson regression, spearman correlations and zero-inflated Poisson regression were used to calculate the degree of association between the abundance of larval Anopheles species and environmental factors. From the 300 larval habitats sampled, 5,568 Anopheles larvae were collected and of these, 2,263 (40.6%) were identified to species. Collections represented 16 Anopheles species with Anopheles vagus (26.4%, n = 598) as the dominant species. A total of 16 Anopheles larval habitat types were identified. Larval abundance was significantly different (P < 0.05) among habitats with pond (40%, n = 914) and rice field (34%, n = 779) implicated to be the most utilized. Larval abundance varied significantly (P < 0.05) with habitat characteristics. Most of the larvae were collected from sites with a range of pH from 7.0 to 8.0. Data obtained from this study revealed both natural and human-created larval habitats were favorable for anopheline larval survival and development. Such information elucidates plausible drivers of high anopheline diversity, high vector abundance, changes in relative species abundance from historic data, and sustained transmission of malaria in endemic areas of Bangladesh. PMID- 29182781 TI - Resistance in 27 Rice Cultivars to Sugarcane Borer (Lepidoptera: Crambidae). AB - Rice (Oryza sativa L.) is considered one of the most important crops in the world, and the sugarcane borer, Diatraea saccharalis Fabricius (Lepidoptera: Crambidae), is among the key pests damaging the crop in the Americas. The objective of this work was to identify rice genotypes as a source of resistance to D. saccharalis. Rice plants were infested in the greenhouse and subsequently evaluated for damage, larval weight and survival, and stem size. The cultivars 'Bonanca', 'Caripuna', 'IR 42', 'Canela de Ferro', 'SWA Norte', 'BR IRGA 409', 'Pepita', 'Serra Dourada', 'Araguaia', 'Xingu', 'Tangara', and 'Soberana' showed antibiosis antixenosis, or both to D. saccharalis. These cultivars may be used as donor sources in the breeding program and used directly by Brazilian farmers as a component of rice-integrated pest management. PMID- 29182783 TI - Persistent smoking rate after coronary revascularization and factors related to smoking cessation in Turkey. AB - Background: Although smoking is an established risk factor for coronary artery disease, smoking cessation efforts, as part of a lifestyle change, have been disappointing so far. Therefore, assessing current smoking trends and identifying patients who are at risk of smoking continuation is of paramount importance. In this study, our aim was to assess current smoking rates after coronary revascularization as of 2017, and to define factors that potentially affect smoking cessation. Methods: Overall, 350 patients who had undergone coronary revascularization, either by percutaneous coronary intervention or bypass surgery were included in this cross-sectional, observational study. Patients were queried for various sociodemographic characteristics and smoking habits. Disease related data were obtained from the hospital archives. Results: The overall smoking rate was 57% after coronary revascularization. Age, bypass surgery and the occurrence of in-hospital adverse events were found to be independent predictors of smoking cessation in multivariate analysis. Conclusions: Despite efforts, smoking rates after coronary intervention remain substantially high. Therefore, a multidisciplinary approach to smoking cessation that incorporates cardiac rehabilitation programs and medications should be implemented in clinical practice.

AB - A redescription, with a discussion of new features and illustrations, for all life stages is presented for the parasitic mite Periglischrus herrerai Machado Allison associated with the common vampire bat Desmodus rotundus (Geoffoy), including a description of the heteromorphic female and the first description of its female deutonymph. In addition, the morphological variation of P. herrerai is evaluated by morphometric analysis of the adults, concluding that there is an evident geographic variation throughout the neotropics. This study was possible by using type material of P. herrerai from the Machado-Allison collection, and voucher specimens from other collections, and specimens from an extensive surveying of hematophagous bats in some localities of the Pacific and Atlantic versants, and central Mexico. PMID- 29182785 TI - Antibiotic therapy in neonates and impact on gut microbiota and antibiotic resistance development: a systematic review. AB - Objectives: To systematically review the impact of antibiotic therapy in the neonatal period on changes in the gut microbiota and/or antibiotic resistance development. Methods: Data sources were PubMed, Embase, Medline and the Cochrane Database, supplemented by manual searches of reference lists. Randomized controlled trials (RCTs) and observational studies were included if they provided data on different categories of antibiotic treatment (yes versus no, long versus short duration and/or broad- versus narrow-spectrum regimens) and subsequent changes in the gut microbiota and/or antibiotic resistance development. We evaluated risk of bias using the Cochrane Handbook, adapted to include observational studies. When appropriate, we used the vote-counting method to perform semi-quantitative meta-analyses. We applied the Grades of Recommendation, Assessment, Development and Evaluation approach to rate the quality of evidence (QoE). Study protocol registration: PROSPERO CRD42015026743. Results: We included 48 studies, comprising 3 RCTs and 45 observational studies. Prolonged antibiotic treatment was associated with reduced gut microbial diversity in all three studies investigating this outcome (very low QoE). Antibiotic treatment was associated with reduced colonization rates of protective commensal anaerobic bacteria in four of five studies (very low QoE). However, all three categories of antibiotic treatment were associated with an increased risk of antibiotic resistance development, in particular MDR in Gram-negative bacteria, and we graded the QoE for these outcomes as moderate. Conclusions: We are moderately confident that antibiotic treatment leads to antibiotic resistance development in neonates and it may also induce potentially disease-promoting gut microbiota alterations. Our findings emphasize the need to reduce unnecessary antibiotic treatment in neonates. PMID- 29182787 TI - Dynamics of phosphorus nutrition, allocation and growth of young beech (Fagus sylvatica L.) trees in P-rich and P-poor forest soil. AB - To investigate how long-lived forest trees cope with low soil phosphorus (P) availabilities, we characterized P nutrition of beech (Fagus sylvatica, L.) in soils from P-rich and P-poor beech forests throughout an annual growth cycle. Young trees were excavated with intact soil cores in mono-specific beech forests, kept under common garden conditions, and used for 33P labeling, analyses of P uptake, P content and biomass during five phenological stages (dormancy in winter, bud swelling in early spring, mature leaves in early and late summer, and senescent leaves in fall). Seasonal allocation patterns showed that young, emerging leaves were preferred sinks for P under P-poor conditions, thereby keeping foliar P concentrations at levels similar to those of trees grown in P rich soil. Phosphorus concentrations in stems and roots of trees from the P-poor conditions were lower than those from P-rich conditions. Coarse roots were the main P storage tissue, supplying inorganic P to newly formed leaves, originating from the inorganic and organic P pools under low and high P conditions, respectively. Beech trees in P-poor soil exhibited net biomass increment early in the annual growth along with a strong P deficit, which was replenished by enhanced uptake in late summer and fall. Trees in P-rich soil grew until late summer, and showed a moderate P decline in organic pools and recovery late in fall, which coincided with elevated P uptake from soil. Beech in P-poor soil produced more biomass per unit of P but at a slower growth rate than those in P rich soil, thereby exhibiting similar P-use efficiencies. Temporal decoupling of growth and P acquisition in combination with internal P trade-off between storage tissues and leaves facilitated flexible acclimation of beech to a wide range of soil P availabilities. PMID- 29182786 TI - Abscisic acid affects expression of citrus FT homologs upon floral induction by low temperature in Satsuma mandarin (Citrus unshiu Marc.). AB - After a long juvenile period, citrus trees undergo seasonal flowering cycles. Under natural conditions, citrus flowering is regulated mainly by low ambient temperatures around 15-20 degrees C and water deficit stress. Recent studies have revealed that fluctuations in the expression of citrus homologs of FLOWERING LOCUS T (FT, encoding a flowering integrator) are correlated with their presumed role as flower-promoting signals. Previous ectopic expression analyses have demonstrated the flower-promoting function of citrus FT homologs. In this study, we examined whether abscisic acid (ABA) affects the expression of FT homologs and the flowering induced by low ambient temperatures. Application of exogenous ABA to potted Satsuma mandarin (Citrus unshiu Marc.) trees resulted in transient accumulation of citrus FT homolog transcripts. The promoter of one citrus FT homolog, CiFT3, was active in transgenic A. thaliana (Arabidopsis thaliana) and responded to exogenous and endogenous ABA. CiFT3 is preferentially expressed in shoots, and its expression was affected by flower-inductive treatments. Endogenous ABA accumulated in mandarin shoots during the floral induction period at 15 degrees C and under field conditions. The accumulation of ABA was correlated with the accumulation of FT homolog transcripts and flowering intensity. It was consistent with changes in the expression of genes related to ABA metabolism. The abundance of carotenoid precursors that serve as substrates for ABA biosynthesis decreased in leaves during the accumulation of ABA. Our data indicate that ABA and carotenoid precursors in leaves influence the flowering of mandarin trees induced by low temperature. PMID- 29182788 TI - Does winter desiccation account for seasonal increases in supercooling capacity of Norway spruce bud primordia? AB - Bud primordia of Picea abies (L.) H. Karst. remain ice free at subzero temperatures by supercooling. Once ice forms inside the primordium, it is immediately injured. Supercooling capacity increases seasonally from ~-5 degrees C to as much as -50 degrees C by currently unknown mechanisms. Among other prerequisites, dehydration of tissues over the winter months has been considered to play a key role in freezing tolerance. In this regard, the water content of bud primordia may be crucial, especially in reference to supercooling. In order to assess the role of dehydration in supercooling capacity, seasonal changes in supercooling capacity and the water potential of bud primordia of Picea abies (L.) H. Karst were measured at two sites that differed by 1298 m in elevation, after artificial frost hardening and dehardening treatments and after controlled bench drying. The extent of supercooling of bud primordia varied from -7 degrees C in summer to -24.6 degrees C in winter, a difference of 17.6 -19.3 K. Total actual water potential (Psitact) of bud primordia was -2 MPa in summer and decreased to a mean of -3.8 MPa in midwinter. The decline involved dehydration, and to a lesser extent, osmoregulation. At decreased Psitact values (<3.0 MPa), supercooling capacity significantly increased <-19.5 degrees C, however, the correlation between actual water potential and supercooling capacity was poor. Frost-hardening treatments increased the supercooling capacity of bud primordia ( 0.6 K day-1) and lowered Psitact (-0.2 MPa day-1). Frost-dehardening treatments reduced supercooling capacity (+1.1 K day-1), and at the same time, increased Psitact (+0.3 MPa day-1). In contrast, artificial drying of bud primordia in the range observed seasonally (-2.0 MPa) had no effect on supercooling capacity. These results suggest that there is no causal relationship between desiccation and the supercooling capacity of bud primordia in P. abies, but rather it involves other compounds within the cells of the bud primordium that reduce the water potential.

PMID- 29182790 TI - Validation of the Itch Severity Item as a Measurement Tool for Pruritus in Patients with Psoriasis: Results from a Phase 3 Tofacitinib Program. AB - Tofacitinib is an oral Janus kinase inhibitor. This post-hoc analysis aimed to investigate the psychometric properties of the Itch Severity Item (ISI), a numeric rating scale from 0 (no itching) to 10 (worst possible itching) for pruritus in psoriasis, and review the effect of tofacitinib on pruritus in patients with psoriasis participating in Phase 3 studies (N = 3,641). The ISI showed high test-retest reliability (intra-class correlation coefficient: 0.84). The clinically important difference was defined as a 1.48-point change, using Patient Global Assessment as an anchor. Mean changes from baseline in ISI scores with tofacitinib were significantly greater than placebo by Day 2 and exceeded the clinically important difference by Week 4 and Week 2 for tofacitinib 5 and 10 mg twice daily, respectively. The sound psychometric properties of the ISI as an assessment tool for pruritus in psoriasis were confirmed. Tofacitinib provided clinically meaningful improvements in psoriatic pruritus versus placebo. PMID- 29182791 TI - Substance P Antagonist Aprepitant Shows no Additive Effect Compared with Standardized Topical Treatment Alone in Patients with Atopic Dermatitis. AB - Atopic dermatitis (AD) is a chronic, itchy, inflammatory skin disorder that may worsen due to stress and anxiety. Tachykinins have been suggested to be involved in the inflammation in AD, as well as pruritus. Aprepitant is a NK-1 receptor antagonist. This open randomized trial evaluated the effect of aprepitant added to topical treatment in adult patients with moderate-severe AD. The treatment group (n = 19) received 80 mg/day aprepitant for 7 days as a supplement to standardized topical treatment with a moderately strong steroid and a moisturizer. The control group (n = 20) received topical treatment alone. Patients were monitored for the extent of the disease (using SCORing of Atopic Dermatitis; SCORAD), pruritus, and scratching movements. In both the aprepitant treated and the control groups there was a decrease in SCORAD, pruritus and scratching movements. However, there was no significant additional improvement in any of these parameters in the aprepitant-treated group compared with the control group. PMID- 29182792 TI - Ex vivo Culture of Duodenal Biopsies from Patients with Dermatitis Herpetiformis Indicates that Transglutaminase 3 Antibody Production Occurs in the Gut. AB - Coeliac disease and dermatitis herpetiformis (DH) are characterized by autoantibodies targeting transglutaminase (TG)2 and TG3, respectively. Previous studies show that TG2 antibodies are produced in the gut and can be assessed in organ culture of small-intestinal biopsies from patients with coeliac disease. Thus far, no studies have investigated TG3 antibodies in organ culture of biopsies from patients with DH, or exploited the method in DH. The aim of this study was to investigate TG3 and TG2 antibody responses in serum and small intestinal biopsies from patients with DH with active disease, and from those in remission. The majority of patients with DH were negative for both serum and organ culture medium TG2-targeting antibodies. Surprisingly, patients with active DH secreted TG3 antibodies into the culture medium despite seronegativity. In patients secreting high levels of TG3 antibodies into the culture medium, we also detected TG3-antibody-positive cells in the small-intestinal mucosa. These findings suggest that TG3 antibodies can be investigated in the organ culture system and that their secretion occurs in the small intestine, especially in active DH. PMID- 29182794 TI - Acquired Transverse Stripes on the Fingernails: A Quiz. PMID- 29182793 TI - Atypical Hand, Foot, and Mouth Disease Caused by Coxsackievirus A6 in Denmark: A Diagnostic Mimicker. AB - Since 2008, outbreaks of atypical hand, foot, and mouth disease (HFMD) in children and adults have been reported worldwide. The majority of these outbreaks are caused by a new lineage of Coxsackie virus A6 (CV-A6) presenting a more severe clinical phenotype than the classical childhood HFMD caused by CV-A16. Between June 2014 and January 2016, 23 cases of atypical HFMD disease presented at a Dermatology Department at a regional University Hospital in Denmark. Patients were referred by general practitioners and dermatologists with a variety of clinical diagnoses, including eczema herpeticum, vasculitis, syphilis, dermatophytid, erythema multiforme and Stevens-Johnson syndrome. Three adults and 3 children required hospitalization due to extensive skin involvement and fever. All reported patients had laboratory-confirmed enterovirus infection. This study demonstrated an upsurge in atypical HFMD caused by CV-A6 in the Region of Southern Denmark and that atypical HFMD can be difficult to diagnose clinically as it may mimic other severe skin diseases. PMID- 29182795 TI - Epidermolysis Bullosa (EB) Acquisita in an Adult Patient with Previously Unrecognized Mild Dystrophic EB and Biallelic COL7A1 Mutations. AB - Circulating anti-type VII collagen autoantibodies are frequently detected in patients with recessive dystrophic epidermolysis bullosa (RDEB). However, evidence supporting their pathogenic role in inducing epidermolysis bullosa acquisita (EBA) has been provided for only one individual with dominant dystrophic epidermolysis bullosa (DDEB). We describe here a patient who presented with dystrophic toenails since early childhood and developed trauma-induced skin blisters and oral erosions at age 26 years. Direct immunofluorescence showed IgG deposits with a u-serrated pattern along the cutaneous basement membrane zone, while no change in the expression of collagen VII could be detected by antigen mapping. High-titre anti-collagen VII antibodies were detected by enzyme-linked immunoassay (ELISA). In parallel, sequencing of epidermolysis bullosa (EB) genes identified compound heterozygous COL7A1 missense c.410G>A (p.Arg137Gln) and splicing c.3674C>T (p.Ala1225_Gln1241del) mutations, previously unrecognized in dystrophic epidermolysis bullosa (DEB). Thus, our patient had RDEB "nails-only" and developed mechanobullous EBA in adulthood. These data support a pathogenic role of circulating autoantibodies to collagen VII in inducing EBA in selected patients with DEB. Unforeseen worsening of skin symptoms in DEB should prompt laboratory investigations for EBA. PMID- 29182796 TI - Nodular Melanoma: A Histopathologic Entity? PMID- 29182797 TI - Palliative chemotherapy and targeted therapies for esophageal and gastroesophageal junction cancer. AB - BACKGROUND: Almost half of people with esophageal or gastroesophageal junction cancer have metastatic disease at the time of diagnosis. Chemotherapy and targeted therapies are increasingly used with a palliative intent to control tumor growth, improve quality of life, and prolong survival. To date, and with the exception of ramucirumab, evidence for the efficacy of palliative treatments for esophageal and gastroesophageal cancer is lacking. OBJECTIVES: To assess the effects of cytostatic or targeted therapy for treating esophageal or gastroesophageal junction cancer with palliative intent. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Web of Science, PubMed Publisher, Google Scholar, and trial registries up to 13 May 2015, and we handsearched the reference lists of studies. We did not restrict the search to publications in English. Additional searches were run in September 2017 prior to publication, and they are listed in the 'Studies awaiting assessment' section. SELECTION CRITERIA: We included randomized controlled trials (RCTs) on palliative chemotherapy and/or targeted therapy versus best supportive care or control in people with esophageal or gastroesophageal junction cancer. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data. We assessed the quality and risk of bias of eligible studies according to the Cochrane Handbook for Systematic Reviews of Interventions. We calculated pooled estimates of effect using an inverse variance random-effects model for meta-analysis. MAIN RESULTS: We identified 41 RCTs with 11,853 participants for inclusion in the review as well as 49 ongoing studies. For the main comparison of adding a cytostatic and/or targeted agent to a control arm, we included 11 studies with 1347 participants. This analysis demonstrated an increase in overall survival in favor of the arm with an additional cytostatic or targeted therapeutic agent with a hazard ratio (HR) of 0.75 (95% confidence interval (CI) 0.68 to 0.84, high-quality evidence). The median increased survival time was one month. Five studies in 750 participants contributed data to the comparison of palliative therapy versus best supportive care. We found a benefit in overall survival in favor of the group receiving palliative chemotherapy and/or targeted therapy compared to best supportive care (HR 0.81, 95% CI 0.71 to 0.92, high-quality evidence). Subcomparisons including only people receiving second-line therapies, chemotherapies, targeted therapies, adenocarcinomas, and squamous cell carcinomas all showed a similar benefit. The only individual agent that more than one study found to improve both overall survival and progression free survival was ramucirumab. Palliative chemotherapy and/or targeted therapy increased the frequency of grade 3 or higher treatment-related toxicity. However, treatment-related deaths did not occur more frequently. Quality of life often improved in the arm with an additional agent. AUTHORS' CONCLUSIONS: People who receive more chemotherapeutic or targeted therapeutic agents have an increased overall survival compared to people who receive less. These agents, administered as both first-line or second-line treatments, also led to better overall survival than best supportive care. With the exception of ramucirumab, it remains unclear which other individual agents cause the survival benefit. Although treatment associated toxicities of grade 3 or more occurred more frequently in arms with an additional chemotherapy or targeted therapy agent, there is no evidence that palliative chemotherapy and/or targeted therapy decrease quality of life. Based on this meta-analysis, palliative chemotherapy and/or targeted therapy can be considered standard care for esophageal and gastroesophageal junction carcinoma. PMID- 29182798 TI - Pharmacological interventions for pain relief during orthodontic treatment. AB - BACKGROUND: Pain is a common side effect of orthodontic treatment. It increases in proportion to the amount of force applied to the teeth, and the type of orthodontic appliance used can affect the intensity of the pain. Pain during orthodontic treatment has been shown to be the most common reason for people wanting to discontinue treatment, and has been ranked as the worst aspect of treatment. Although pharmacological methods of pain relief have been investigated, there remains some uncertainty among orthodontists about which painkillers are most suitable and whether pre-emptive analgesia is beneficial. We conducted this Cochrane Review to assess and summarize the international evidence relating to the effectiveness of analgesics for preventing this unwanted side effect associated with orthodontic treatment. OBJECTIVES: The objectives of this review are to determine:- the effectiveness of drug interventions for pain relief during orthodontic treatment; and- whether there is a difference in the analgesic effect provided by different types, forms and doses of analgesia taken during orthodontic treatment. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases: the Cochrane Oral Health Trials Register (to 19 June 2017), the Cochrane Central Register of Controlled Trials (CENTRAL;the Cochrane Library 2016, Issue 7), MEDLINE Ovid (1946 to 19 June 2017), Embase Ovid (1980 to 19 June 2017) and CINAHL EBSCO (Cumulative Index to Nursing and Allied Health Literature; 1937 to 19 June 2017). The US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched on the 19 June 2017 for ongoing studies. We placed no restrictions on language or date of publication when searching the electronic databases. SELECTION CRITERIA: We included randomized controlled trials (RCTs) relating to pain control during orthodontic treatment. Pain could be measured on a visual analogue scale (VAS), numerical rating scale (NRS) or categorical scale. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the search results, agreed the studies to be included and extracted information from the included studies regarding methods, participants, interventions, outcomes, harms and results. We planned to resolve any discrepancies or disagreements through discussion. We used the Cochrane 'Risk of bias' tool to assess the risk of bias in the studies. MAIN RESULTS: We identified 32 relevant RCTs, which included 3110 participants aged 9 to 34 years, 2348 of whom we were able to include in our analyses. Seventeen of the studies had more than two arms. We were able to use data from 12 trials in meta-analyses that compared analgesics versus control (no treatment or a placebo); nine that compared non-steroidal anti-inflammatories (NSAIDs) versus paracetamol; and two that compared pre-emptive versus post-treatment ibuprofen for pain control following orthodontic treatment. One study provided data for the comparison of NSAIDs versus local anaesthetic.We found moderate-quality evidence that analgesics effectively reduced pain following orthodontic treatment when compared to no treatment or a placebo at 2 hours (mean difference (MD) -11.66 mm on a 0 to 100 mm VAS, 95% confidence interval (CI) -16.15 to -7.17; 10 studies, 685 participants), 6 hours (MD -24.27 mm on a VAS, 95% CI -31.44 to -17.11; 9 studies, 535 participants) and 24 hours (MD -21.19 mm on a VAS, 95% CI -28.31 to 14.06; 12 studies, 1012 participants).We did not find any evidence of a difference in efficacy between NSAID and paracetamol at 2, 6 or 24 hours (at 24 hours: MD -0.51, 95% CI -8.93 to 7.92; 9 studies, 734 participants; low-quality evidence).Very low-quality evidence suggested pre-emptive ibuprofen gave better pain relief at 2 hours than ibuprofen taken post treatment (MD -11.30, 95% CI 16.27 to -6.33; one study, 41 participants), however, the difference was no longer significant at 6 or 24 hours.A single study of 48 participants compared topical NSAIDs versus local anaesthetic and showed no evidence of a difference in the effectiveness of the interventions (very low-quality evidence).Use of rescue analgesia was poorly reported. The very low-quality evidence did not show evidence of a difference between participants taking ibuprofen and participants taking paracetamol (relative risk (RR) 1.5, 95% CI 0.6 to 3.6). Nor did we find evidence of a difference between groups in likelihood of requiring rescue analgesia when ibuprofen was taken pre-emptively compared to after treatment (RR 0.8, 95% CI 0.3 to 1.9).Adverse effects were identified in one study, with one participant developing a rash that required treatment with antihistamines. This was provisionally diagnosed as a hypersensitivity to paracetamol. AUTHORS' CONCLUSIONS: Analgesics are more effective at reducing pain following orthodontic treatment than placebo or no treatment. Low-quality evidence did not show a difference in effectiveness between systemic NSAIDs compared with paracetamol, or topical NSAIDs compared with local anaesthetic. More high-quality research is needed to investigate these comparisons, and to evaluate pre-emptive versus post treatment administration of analgesics. PMID- 29182799 TI - Inhaled magnesium sulfate in the treatment of acute asthma. AB - BACKGROUND: Asthma exacerbations can be frequent and range in severity from mild to life-threatening. The use of magnesium sulfate (MgSO4) is one of numerous treatment options available during acute exacerbations. While the efficacy of intravenous MgSO4 has been demonstrated, the role of inhaled MgSO4 is less clear. OBJECTIVES: To determine the efficacy and safety of inhaled MgSO4 administered in acute asthma. SPECIFIC AIMS: to quantify the effects of inhaled MgSO4 I) in addition to combination treatment with inhaled beta2-agonist and ipratropium bromide; ii) in addition to inhaled beta2-agonist; and iii) in comparison to inhaled beta2-agonist. SEARCH METHODS: We identified randomised controlled trials (RCTs) from the Cochrane Airways Group register of trials and online trials registries in September 2017. We supplemented these with searches of the reference lists of published studies and by contact with trialists. SELECTION CRITERIA: RCTs including adults or children with acute asthma were eligible for inclusion in the review. We included studies if patients were treated with nebulised MgSO4 alone or in combination with beta2-agonist or ipratropium bromide or both, and were compared with the same co-intervention alone or inactive control. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial selection, data extraction and risk of bias. We made efforts to collect missing data from authors. We present results, with their 95% confidence intervals (CIs), as mean differences (MDs) or standardised mean differences (SMDs) for pulmonary function, clinical severity scores and vital signs; and risk ratios (RRs) for hospital admission. We used risk differences (RDs) to analyse adverse events because events were rare. MAIN RESULTS: Twenty-five trials (43 references) of varying methodological quality were eligible; they included 2907 randomised patients (2777 patients completed). Nine of the 25 included studies involved adults; four included adult and paediatric patients; eight studies enrolled paediatric patients; and in the remaining four studies the age of participants was not stated. The design, definitions, intervention and outcomes were different in all 25 studies; this heterogeneity made direct comparisons difficult. The quality of the evidence presented ranged from high to very low, with most outcomes graded as low or very low. This was largely due to concerns about the methodological quality of the included studies and imprecision in the pooled effect estimates. Inhaled magnesium sulfate in addition to inhaled beta2 agonist and ipratropiumWe included seven studies in this comparison. Although some individual studies reported improvement in lung function indices favouring the intervention group, results were inconsistent overall and the largest study reporting this outcome found no between-group difference at 60 minutes (MD -0.3 % predicted peak expiratory flow rate (PEFR), 95% CI -2.71% to 2.11%). Admissions to hospital at initial presentation may be reduced by the addition of inhaled magnesium sulfate (RR 0.95, 95% CI 0.91 to 1.00; participants = 1308; studies = 4; I2 = 52%) but no difference was detected for re-admissions or escalation of care to ITU/HDU. Serious adverse events during admission were rare. There was no difference between groups for all adverse events during admission (RD 0.01, 95% CI -0.03 to 0.05; participants = 1197; studies = 2). Inhaled magnesium sulfate in addition to inhaled beta2-agonistWe included 13 studies in this comparison. Although some individual studies reported improvement in lung function indices favouring the intervention group, none of the pooled results showed a conclusive benefit as measured by FEV1 or PEFR. Pooled results for hospital admission showed a point estimate that favoured the combination of MgSO4 and beta2-agonist, but the confidence interval includes the possibility of admissions increasing in the intervention group (RR 0.78, 95% CI 0.52 to 1.15; participants = 375; studies = 6; I2 = 0%). There were no serious adverse events reported by any of the included studies and no between-group difference for all adverse events (RD -0.01, 95% CI 0.05 to 0.03; participants = 694; studies = 5). Inhaled magnesium sulfate versus inhaled beta2-agonistWe included four studies in this comparison. The evidence for the efficacy of beta2-agonists in acute asthma is well-established and therefore this could be considered a historical comparison. Two studies reported a benefit of beta2-agonist over MgSO4 alone for PEFR and two studies reported no difference; we did not pool these results. Admissions to hospital were only reported by one small study and events were rare, leading to an uncertain result. No serious adverse events were reported in any of the studies in this comparison; one small study reported mild to moderate adverse events but the result is imprecise. AUTHORS' CONCLUSIONS: Treatment with nebulised MgSO4 may result in modest additional benefits for lung function and hospital admission when added to inhaled beta2-agonists and ipratropium bromide, but our confidence in the evidence is low and there remains substantial uncertainty. The recent large, well designed trials have generally not demonstrated clinically important benefits. Nebulised MgSO4 does not appear to be associated with an increase in serious adverse events. Individual studies suggest that those with more severe attacks and attacks of shorter duration may experience a greater benefit but further research into subgroups is warranted.Despite including 24 trials in this review update we were unable to pool data for all outcomes of interest and this has limited the strength of the conclusions reached. A core outcomes set for studies in acute asthma is needed. This is particularly important in paediatric studies where measuring lung function at the time of an exacerbation may not be possible. Placebo-controlled trials in patients not responding to standard maximal treatment, including inhaled beta2-agonists and ipratropium bromide and systemic steroids, may help establish if nebulised MgSO4 has a role in acute asthma. However, the accumulating evidence suggests that a substantial benefit may be unlikely. PMID- 29182801 TI - [Harmonization of TSH Measurements.] AB - The measured concentration of thyroid stimulating hormone (TSH) differs depending on the reagents used. Harmonization of TSH is crucial because the decision limits are described in current clinical practice guide- lines as absolute values, e.g. 2.5 mIU/L in early pregnancy. In this study, we tried to harmonize the report- ed concentrations of TSH using the all-procedure trimmed mean. TSH was measured in 146 serum samples, with values ranging from 0.01 to 18.8 mIU/L, using 4 immunoassays. The concentration of TSH was highest with E test TOSOH and lowest with LUMIPULSE. The concentrations with each reagent were recalculated with the following formulas: E test TOSOH 0.855x-0.014; ECLusys 0.993x+0.079; ARCHITECT 1.041x- 0.010; and LUMIPULSE 1.096x-0.015. Recalculation eliminated the between assay discrepancy. These formulas may be used until harmonization of TSH is achieved by the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC).

AB - BACKGROUND: Pulmonary tuberculosis is usually diagnosed when symptomatic individuals seek care at healthcare facilities, and healthcare workers have a minimal role in promoting the health-seeking behaviour. However, some policy specialists believe the healthcare system could be more active in tuberculosis diagnosis to increase tuberculosis case detection. OBJECTIVES: To evaluate the effectiveness of different strategies to increase tuberculosis case detection through improving access (geographical, financial, educational) to tuberculosis diagnosis at primary healthcare or community-level services. SEARCH METHODS: We searched the following databases for relevant studies up to 19 December 2016: the Cochrane Infectious Disease Group Specialized Register; the Cochrane Central Register of Controlled Trials (CENTRAL), published in the Cochrane Library, Issue 12, 2016; MEDLINE; Embase; Science Citation Index Expanded, Social Sciences Citation Index; BIOSIS Previews; and Scopus. We also searched the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP), ClinicalTrials.gov, and the metaRegister of Controlled Trials (mRCT) for ongoing trials. SELECTION CRITERIA: Randomized and non-randomized controlled studies comparing any intervention that aims to improve access to a tuberculosis diagnosis, with no intervention or an alternative intervention. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for eligibility and risk of bias, and extracted data. We compared interventions using risk ratios (RR) and 95% confidence intervals (CI). We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS: We included nine cluster-randomized trials, one individual randomized trial, and seven non-randomized controlled studies. Nine studies were conducted in sub-Saharan Africa (Ethiopia, Nigeria, South Africa, Zambia, and Zimbabwe), six in Asia (Bangladesh, Cambodia, India, Nepal, and Pakistan), and two in South America (Brazil and Colombia); which are all high tuberculosis prevalence areas.Tuberculosis outreach screening, using house-to-house visits, sometimes combined with printed information about going to clinic, may increase tuberculosis case detection (RR 1.24, 95% CI 0.86 to 1.79; 4 trials, 6,458,591 participants in 297 clusters, low-certainty evidence); and probably increases case detection in areas with tuberculosis prevalence of 5% or more (RR 1.52, 95% CI 1.10 to 2.09; 3 trials, 155,918 participants, moderate certainty evidence; prespecified stratified analysis). These interventions may lower the early default (prior to starting treatment) or default during treatment (RR 0.67, 95% CI 0.47 to 0.96; 3 trials, 849 participants, low-certainty evidence). However, this intervention may have may have little or no effect on treatment success (RR 1.07, 95% CI 1.00 to 1.15; 3 trials, 849 participants, low certainty evidence), and we do not know if there is an effect on treatment failure or mortality. One study investigated long-term prevalence in the community, but with no clear effect due to imprecision and differences in care between the two groups (RR 1.14, 95% CI 0.65 to 2.00; 1 trial, 556,836 participants, very low-certainty evidence).Four studies examined health promotion activities to encourage people to attend for screening, including mass media strategies and more locally organized activities. There was some increase, but this could have been related to temporal trends, with no corresponding increase in case notifications, and no evidence of an effect on long-term tuberculosis prevalence. Two studies examined the effects of two to six nurse practitioner educational sessions in tuberculosis diagnosis, with no clear effect on tuberculosis cases detected. One trial compared mobile clinics every five days with house-to-house screening every six months, and showed an increase in tuberculosis cases.There was also insufficient evidence to determine if sustained improvements in case detection impact on long-term tuberculosis prevalence; this was evaluated in one study, which indicated little or no effect after four years of either contact tracing, extensive health promotion activities, or both (RR 1.31, 95% CI 0.75 to 2.30; 1 study, 405,788 participants in 12 clusters, very low certainty evidence). AUTHORS' CONCLUSIONS: The available evidence demonstrates that when used in appropriate settings, active case-finding approaches may result in increase in tuberculosis case detection in the short term. The effect of active case finding on treatment outcome needs to be further evaluated in sufficiently powered studies.

We analyzed coagulation factor VII gene (F7) of a patient with FVII deficiency and used expression studies to investigate the effect of a missense mutation on FVII secretion. The proband, a 69-year-old Japanese woman, had a history of postpartum bleeding and excessive bleeding after dental extrac- tion. She was found to have mildly increased PT-INR (1.17) before an ophthalmic operation. FVII activity and antigen were reduced (29.0% and 32.8%). Suspecting that the proband was FVII deficient, we analyzed F7 of the patient. Sequence analysis revealed that the patient was heterozygous for a point mutation (p.Arg337Cys) in the catalytic domain and polymorphisms: the decanucleotide insertion at the promoter re- gion, dimorphism (c.525C >T) in exon 5, and p.Arg413Gln in exon 8. Haplotype analysis clarified that p.Arg337Cys was located on the p.Arg413 allele (Ml allele). The other allele had the p.Arg413Gln polymor- phism(M2 allele) which is known to produce less FVII. Expression studies revealed that p.Arg337Cys causes impairment of FVII secretion. Insufficient secretion of FVII arising from both the p.Arg337Cys/M1 allele and the p.Arg337/M2 allele might lower the FVII level of this patient(<50%). The FVII level in a heterozygous FVII deficient patient might be influenced by F7 polymorphisms on the normal allele. There- fore, genetic analyses are important for the diagnosis of heterozygous FVII deficiency.

Various organs work together to form a net- work, and it has been suggested that this is how homeostasis is maintained in the human body. The kidneys play a vital role in maintaining homeostasis through regulating processes such as metabolism and endocrine activity. In fact, the onset, progression, and chronic nature of kidney disease leads to the development of cardiovascular disease that can itself lead to systemic organ damage. We refer to this attempt to elucidate such a bodily network as the "Comprehensive Medicine in Humans" study. We hope to reveal such mecha- nisms, and develop new diagnostic and treatment methods. We previously reported on nephro-vascular and nephro-pulmonary networks. Chronic kidney disease (CKD) patients, even when not suffering from diabe- tes mellitus, have been shown to exhibit a progression in atherosclerosis. Furthermore, a decline in the kidney function is closely linked to a decline in the pulmonary diffusion capacity. It has therefore been sug- gested that networks exist involving the kidneys and various other organs. Increasing CKD rates in a highly aged society, along with accompanying illnesses, can be understood from a whole-body network perspective. We aim to gain knowledge that can aid in disease prevention, as well as help develop new diagnostic methods and treatments for patients suffering from kidney disease.

Liquid biop- sies detect circulating tumor cells (CTCs), fragments of tumor DNA and exosomes that are shed into the blood from the primary tumor and from metastatic sites. Liquid biopsies offer what tissue biopsies cannot due to risks to the patients and costs. Liquid biopsies allow the monitoring of genomic changes in tumors for the diagnosis of early and recurrent cancer and drug effects. In the future, instead of extensive imaging and invasive tissue biopsies, liquid biopsies could be used to guide cancer treatment decisions and even screen for tumors that are not vet visible on imaging. PMID- 29182805 TI - [Liquid Biopsy: Challenges and Possibilities Regarding Its Clinical Application.] AB - Cell-free DNA is "Fragmented DNA found in circulation in the Cell-free component of whole blood". Cell-free DNA derived from tumors is expressed as circulating tumor DNA. Examination of circulating tu- mor DNA for genetic alterations present in the tumor tissue is defined as liquid biopsy. Currently in the cancer field, Cell-free DNA or CTC (Circulating tumor cells) is the main target of "Liquid Biopsy". Acquir- ing Cell-free DNA or CTC presents little challenge because of the recent technological developments. However, we need to improve the efficiency of CTC retrieval, and we also need to establish how to culture the retrieved CTCs. For clinical applications, PGx (Pharmacogenomics) and PGt (Pharmacogenetics) fol- lowing NGS (Next Generation Sequencing) are attractive areas for new and future applications. The intro- duction of "Liquid Biopsy" to the area of clinical trials is already in progress. As an expert group, members of the JSLM (Japanese Society of Laboratory Medicine) need to indicate the presence of quality control or quality management in the area of "Liquid Biopsy". Besides these quality issues, we, as clinical pathologists, need to think about harmonizing our expertise with surgical pathologists, who have historically handled clas- sical biopsies of solid samples. The field of "Liquid Biopsy" has marked potential; however, we need to overcome various obstacles to realize this. PMID- 29182806 TI - [Circulating Tumor DNA (ctDNA) Detection Using BEAMing and Its Clinical Significance.] AB - In cancer, companion diagnostics accompanied by molecular-targeted drugs have been developed and launched over the last decade, leading to marked improvements of patients' treatments and outcomes. Alt- hough most of them are tested using tissue samples, sometimes it is difficult to obtain a biopsy for some types of cancers because of the patient's risk and performance status. Recently, extensive clinical research regarding "Liquid Biopsy", such as circulating tumor DNA (ctDNA), has been performed. It is considered that "Liquid Biopsy" has the potential to overcome the issue of tissue-based molecular diagnostics. "BEAMing" is one of the digital PCR methods invented by Prof. Bert Vogelstein's group from Johns Hop- kins University. This technology enables highly sensitive detection, at 0.01% of ctDNA in plasma, which outperforms general PCR methods. Regarding BEAMing, extensive research on the clinical significance of ctDNA detection has been done, especially in three fields: response prediction, response/recurrence monitoring, and molecular-targeted drug resistance monitoring. In this article, I will discuss the possibility of BEAMing and ctDNA testing as future diagnostics. PMID- 29182807 TI - [Application of Liquid Biopsy for Lung Cancer Treatment.] AB - Liquid biopsy is defined as a non-invasive blood test that detects features of tumor cells, which are shed into the blood stream from the primary tumor and/or metastatic sites. This method is developing based on research on circulating tumor cells (CTCs) and the circulating free/fragments of tumor DNA (cfDNA). CfDNA can be detected in the absence of detectable CTCs, and has been shown to increase with the disease condition. The detection of cfDNA can be used for tumor genotyping, monitoring of the tumor burden, and monitoring minimal residual diseases, and recent results showed that cfDNA is a highly specific biomarker with intermediate sensitivity. Liquid biopsy with cfDNA is promising, and is becoming an alternative to re- biopsy. However, there are some caveats: it has not been elucidated which patients and tumor types can be accessed with cfDNA. Further research is warranted.

Here, we introduce two well-known international volunteer groups, the Peshawar-kai and Rocinantes. The two groups have continued various forms of medical assistance for a long time in Afghanistan and Sudan, respectively, where medical services are severely lacking. In this symposium, we would like to consider what is required in the countries, what is being done there, why they continue their activities, how we can support them, and, finally, what is the true goal of medical volunteer activities. PMID- 29182809 TI - [Current Status and Issues of Clinical Laboratory Testing Expanding into Health Care: How to Challenge Experts of Laboratory Medicine -Remark of Moderators.] AB - Point-of-Care Testing (POCT) has been increasingly implemented in healthcare, on the basis of advances in analysis and information technologies. Wherever POCT is implemented, it needs to be properly and safe- ly performed. However, a concern has been raised that it is preformed without training and support from the clinical laboratory and, thus, testing reliability and patient safety are not sufficiently ensured. Laboratory professionals and experts are expected to play an important role in the solution of this issue, through provid- ing guidance and support in the proper implementation and patient safety of POCT. Hence, this symposium was organized to summarize current situations and issues of POCT expanding into health care, the communi- ty, and home, and to clarify the way to challenge them as laboratory professionals for increased reliability and confidence on performing POCT, contributing to the cost-effectiveness and quality of health-care services. PMID- 29182810 TI - [The Technical Innovation of Medical Engineering and Application Development in POCT Devices.] AB - Medical doctors have been utilizing POCT devices at POC sites (ER, ICU, and operation rooms). Now, POCT devices are used by health care professionals in the physician's office and also for home healthcare. Home healthcare (welfare/nursing care) is a focus area of the MHLW initiative to develop healthcare in order to resolve the "2025 problem". The role of POCT is important in resolving this issue. PMID- 29182811 TI - [Present Status and Problems of Laboratory Test in a Community and at Home: "Sample Measurement Room", Self-Test and Mail-in Test.] AB - In this review, the present status and problems of laboratory tests outside traditional healthcare were dis- cussed. The test group includes the "sample measurement room", self-test, and mail-in test. They will be classified by 2 X 2 viewpoints, sampling/measurement X place/person. As for the "sample measurement room", consultation based on the results cannot be recommended, even if the results are abnormal, although this is often misunderstood. The problems of the "sample measurement room", self-test, and mail-in test can be considered from the viewpoints mentioned above. A sample extraction defect, infection between persons, the data instability by preservation, measurement error, and insufficient quality control are thought to be examples. PMID- 29182812 TI - [Respiratory Function Tests as Physiological Examination in Home Health Care Pulse Oximeter, Peak Flow Meter, and NO Measurement Apparatus.] AB - Daily monitoring of patients with chronic respiratory failure or bronchial asthma to prevent their disease deterioration is required. In home health care, the pulse oximeter for chronic respiratory failure during home oxygen therapy and the peak flow meter or the expiratory nitric oxide (NO) measurement apparatus for bronchial asthma are important. As there are many pitfalls in interpreting the test results, appropriate in- formation needs to be conveyed from the physicians to patients. PMID- 29182813 TI - [Circulatory Function Tests for Home & Community Use.] AB - Currently, the main circulatory function-testing tools for home use are blood pressure monitors and elec- trocardiography devices. Just like blood pressure monitors that are already widespread for home use, some devices with an electrocardiographic function have recently become available for purchase for personal use by the general public. On the other hand, clinic equipment on loan from doctors to patients in need can perform circulatory function tests like 24 hour ambulatory blood pressure monitoring (ABPM), Holter monitoring, and real time electrocardiography. We introduce the actual clinical usage of ABPM and real time electro- cardiography, and discuss the usefulness of these procedures. ABPM uses a blood pressure measurement device worn on the body for 24 hours a day to measure blood pressure at regular intervals. This makes it possible to check blood pressure changes throughout the day in a way in which conventional home-use blood pressure monitors cannot, like during sleep. This method al- lows the identification of masked hypertension like early-morning and nocturnal hypertension, stress hyper- tension including workplace hypertension, and white coat hypertension that only occurs in the doctor's office. Under routine care, there are few opportunities to perform electrocardiography at the time a patient is experiencing symptoms. Now, real-time electrocardiography has begun to be used in routine care, and pa- tients can record an electrocardiogram by themselves anytime, anywhere, and send the data by telephone or the Internet for analysis and diagnosis. Transmission-capable electrocardiography devices can play an im- portant role in the event of dangerous symptoms like arrhythmia, angina, or acute myocardial infarction. The spread of ABPM and event heart monitors is likely to make the early treatment and prevention of stroke and heart disease possible. We are expecting rapid development in this field in the future. PMID- 29182814 TI - [Global Trends in the Use of Point-of-Care Testing Devices and Efforts toward Standardization.] AB - Advances in testing and information technologies have expanded the availability of Point-of-Care Testing (POCT) devices not only in healthcare but also in non healthcare settings. POCT laboratory accreditation under ISO 22870 has been implemented in conjunction with ISO 15189 in European countries. A markedly increasing number of facilities are performing POCT in non-healthcare settings in the United States with a certificate of waiver and in European countries; concerns are being raised on the lack of oversight and re- quirements for personnel qualifications and training. Centers for Disease Control and Prevention have been making efforts to develop educational tools. In ISO Technical Committee 212 (ISO/TC212) on clinical labor- atory testing and in vitro diagnostic test systems, guidance for POCT operators is proposed, being designed as a document for operators in healthcare and non-healthcare settings who lack specific medical laboratory training. In Japan, on the basis of the international efforts on standardization and quality assurance, nation- wide efforts are necessary for increased reliability and confidence on performing POCT to promote the cost- effectiveness and quality of healthcare services.

In iddition. Mr. Mivata (Nikkei BP. Inc.) helned facilitate the symposium. PMID- 29182816 TI - [Bio-Resources and Database for Preemptive Medicine.] AB - Establishing a primary defense for the improvement of individual quality of life by epidemiology and various clinical studies applying bio-resources/database analysis is very important. Furthermore, recent studies on understanding the epigenetic regulatory mechanisms of developmental origins of health and diseases are attracting increasing interest. Therefore, the storing of not only bio-fluid (i.e., blood, urine) but also certain tissues (i.e., placenta, cord) is very important for research. The Resource Center for Health Science (RECHS) and Bio databases Institute of Reproductive and Developmental Medicine (BIRD) have estab- lished Bio-bank and initiated a project based on the development and utilization of bio-resources/database, comprising personal health records (PHR), such as health/medical records including individual records of daily diet and exercise, physically consolidated with bio-resources, taken from the same individuals. These Bio-Resources/Database projects are very important for the establishment of preemptive medicine and un- derstanding the mechanisms of the developmental origins of health and diseases.

Therefore, multiple examinations should be combined for practical diagnosis to facilitate treatment. In symposium 14 (ultrasound and clinical examina- tion), 5 speakers presented how to combine diagnostic methods in their clinical practice.

PMID- 29182818 TI - [View of Clinical Laboratory Physician on Pathophysiological Analysis by Close Cooperation of Clinical Laboratory and Ultrasonography.] AB - I want to give my opinion on what ultrasonography and the clinical laboratory should be to improve medical care. First, the close collaboration between ultrasonography and the clinical laboratory is the most im- portant. The development of technology and translation into the hands of medical technologists have been increasing the usefulness of ultrasonography to provide information for medical care. So, information should be used to interpret and report, respectively. The clinical research should be driven forward by collabora- tion and will result in improving medical care. Second, the system and culture of quality assurance should be established for ultrasonography as was done for clinical chemistry, hematology, etc. At that time, medical technologists who performed ultrasonography had to be aware that their abilities would be evaluated by oth- ers. Finally, it is important for medical technologists to educate young doctors not only on how to perform ultrasonography but also how to interpret images, because ultrasonography has been moving into the hands of medical technologists from doctors. Their sensitivity and view of life affect their works. I am sure of their importance in the clinical laboratory. PMID- 29182819 TI - [The Latest Findings in Liver Diseases -Chairman's Introductory Remarks.] AB - Symposium 15 entitled: "the latest findings in liver diseases", was held at the 62nd Annual Meeting of the Japanese Society of Laboratory Medicine last year in Gifu. It is well-known that there have been marked changes in clinical practice for liver diseases, such as the development of directly acting antivirals for hepati- tis C virus, elucidation of the reactivation of hepatitis B virus, and the increase in the number of patients with non-alcoholic fatty liver disease and non-alcoholic steatohepatitis. Three speakers, Professor Junko Tanaka from Hiroshima University, Professor Yasuhito Tanaka from Nagoya City University, and Assistant Director Toshihide Shima from Saiseikai Suita Hospital, were invited to give a lecture regarding the epidemiological aspects of viral hepatitis, the reactivation of hepatitis B virus, and the current status and monitoring of non-B non-C liver diseases, respectively. This manuscript briefly summarizes the background of this symposium. PMID- 29182820 TI - [Epidemiology of Hepatitis Virus Infection and Its Control from the Epidemiological Point of View.] AB - In Japan, hepatitis and liver cancer measures, based on the hepatitis Basic Measures Law, have been pro- moted for 25 years with a focus on advancing the diagnosis, treatment, and inspection. In 2011, the estimated number of people persistently infected with the hepatitis virus in Japan was esti- mated to be about 2.1-2.8 per million people. In addition, "persistent infections latent in society of people unaware of their infection" has been estimated to involve 777,000 people. Since it is now a time of introducing new drugs for effective anti-viral therapy, in order to continue to more effectively implement the hepatitis and liver cancer measures, regional cooperation, such as the construction of a liver disease patient follow-up system, is important. PMID- 29182821 TI - [Present State of Non-B Non-C Liver Disease-and Its Monitoring.] AB - As the prevalence of lifestyle-related diseases increases, the number of individuals who have abnormal liver function test results with negative HBs antigen and anti-HCV(non-B non-C liver diseases) has been increasing. Non-B non-C liver diseases consist mainly of nonalcoholic fatty liver disease (NAFLD) and al- coholic liver disease. Non-B non-C liver cancers have been increasing in number. The identification of individuals with high risks of liver cancer is crucial for their early diagnosis and treatment. Among NAFLD individuals, nonalcoholic steatohepatitis (NASH) patients with advanced liver fibrosis have a high risk of non-B non-C liver cancers. For the diagnosis of NASH with advanced liver fibrosis, useful parameters are as follows: 1) high value of liver fibrosis markers, such as type 4 collagen 7S, 2) low platelet count (lower than 19 X 104/pL), 3) high value using a scoring system, such as the NAFLD fibrosis score and FIB-4 index, 4) high stiffness value measured by elastography, 5) advanced age, and 6) comorbidity of 3 or 4 types of lifestyle-related diseases. Alcohol drinkers consuming more than 60 g of ethanol a day are at risk of liver cancer. Obesity and diabetes mellitus are also risk factors. Individuals as described above are at risk of non-B non-C liver cancers. AFP is unlikely to show a high value in NASH liver cancer. Regular examination (every 6 months) with sonography and PIVKA-II is rec- ommended for the early diagnosis of non-B non-C liver cancers.

Chronic kidney disease metabolic bone disease (CKD-MBD) starts at early stages of CKD with phosphorus accumulation and consequent initiation of numerous events that result with the development of secondary hyperparathyroidism with changes on bones and extraskeletal tissues. The most important and clinically most relevant consequences of CKD-MBD are vascular calcifications which contribute to cardiovascular mortality. Patients with the increased risk for the development of CKD-MBD should be recognized and treated. Prevention is the most important therapeutic option. The first step should be nutritional counseling with vitamin supplementation if necessary and correction of mineral status. Progression of CKD requires more intensive medicamentous treatment with the additional correction of metabolic acidosis and anemia. Renal replacement therapy should be timely initiated, with the adequate dose of dislaysis. Ideally, preemptive renal transplantion should be offered in individuals without contraindication for immunosuppressive therapy. PMID- 29182824 TI - PATHOLOGICAL CHANGES OF RENAL ARTERIES IN PATIENTS WITH RENAL CELL CARCINOMA. AB - Renal cell carcinoma is the ninth most common cancer in the world. It may have a varied microscopic appear- ance, and the most common histopathological type is clear cell carcinoma. The most common pathological changes of renal arteries are atherosclerosis and fibromuscular dysplasia (FMD). During histopathological evaluation of a kidney specimen containing carcinoma, the renal vein is routinely analyzed, while the renal artery is usually given little attention. Our stud- ies have shown that pathological changes of renal arteries are significantly more frequent in the group of patients with renal cell carcinoma compared with the control group and the group of patients with non-tumor kidney diseases. These relations led us to the conclusion that the onset of renal artery changes is not prior to the carcinoma or non-tumor diseases and that they are formed simultaneously or as a consequence. Further studies should be aimed at determining the incidence of these changes in a larger number of samples and the detection of their possible correlation with renal cell carcinoma. PMID- 29182823 TI - GUIDELINES FOR THE PREVENTION, DETECTION AND THERAPY OF VITAMIN D DEFICIENCY IN ADULTS. AB - It is estimated that over one billion of people around the globe have low serum values of vitamin D, therefore, we can consider vitamin D deficiency as a pandemic and public health problem. Geographic position of Croatia, especially the continental part of the country, is a risk factor for the development of deficiency of vitamin D in the population. The aim of these guidelines is to provide the clinicians with easy and comprehensive tool for prevention, detection and therapy of vitamin D deficienney in healthy population and various groups of patients. They were made as a result of collaboration of clinicians of different backgrounds who are dealing with patients at risk of vitamin D deficiency. These guidelines are evi- dence-based, according to GRADE-system (Grading of Recommendations, Assessment, Development and Evaluation), which describes the level of evidence and strength of recommendation. The main conclusions address the recommended serum vitamin D values in the population which should be between 75 and 125 nmol/L and defining recommended preven- tive and therapeutic dosages of vitamin D in order to reach the adequate levels of serum vitamin D. PMID- 29182825 TI - SOCIODEMOGRAPHIC CHARACTERISTICS INFLUENCE PAIN PERCEPTION IN NON-SMALL CELL LUNG CANCER PATIENTS. AB - BACKGROUND: Lung cancer is the most common malignant disease in men and the third most common in women worldwide. Pain in these patients is a leading and debilitating symptom, among others. OBJECTIVES: The aim of this research was to determine the relationship between the sociodemographic characteristics and pain perception, as measured by visual analogue scale for pain, in patients with non small cell lung cancer. METHODS: This observational, single centre study included both a cross-sectional and prospective cohort design. RESULTS: Forty-one patients with a median age of 61 years (range 56-68) were included. This study showed that subjective perception of pain is related to age and place of residence. Younger patients ( <= 60 years old, p=0.026) and those residing in cities (p=0.03 1) reported feeling worse pain. Age was independently and statistically associated with the relative relief of pain after analgesic therapy (Wald=5.914; ss=1; p=0.015). CONCLUSION: Age, lifestyle, place of residence, and mentality should be considered when evaluating pain percep- tion in patients suffering from chronic pain related to malignant disease in order to provide the best possible medical treat- ment with the goal of improving quality of life. PMID- 29182826 TI - IS THERE ANY ROOM FOR TENDOSCOPY IN THE SURGICAL TREATMENT OF POSTERIOR TIBIAL TENDON INSUFFICIENCY? AB - Posterior tibial tendon insufficiency (PTTI) is nowadays considered to be the main cause of adult-acquired flatfoot deformity (AAFD). The purpose of this study is to report the outcomes of tendoscopic treatment of tibialis poste- rior tendon (TP) in eleven patients with stage 1 or 2 PTTI and failed prior conservative treatment. Tendoscopy was carried out as a solitary procedure in 8 patients, while in 3 patients additional procedures such as ,,mini-open" tubularization of TP or anterior ankle arthroscopy were necessary. In a single patient transfer of flexor digitorum longus tendon was performed as a second stage surgery due to complete rupture of TP. Related with tendoscopic procedure, no complications were re- ported. TP tendoscopy is a useful and beneficial minimally invasive procedure to treat TP pathology at earlier stages of PTTI. It is a technically demanding procedure that requires extensive experience in arthroscopic management of small ioints and excellent knowledge of repional anatomy. PMID- 29182827 TI - GIANT CELL AORTITIS DIAGNOSED WITH PET/CT - PARANEOPLASTIC SYNDROME? AB - Vasculitides are heterogenic group of autoimmune connective tissue diseases which often present difficulties in early diagnosing. Giant cell arteritis is vasculitis of large and medium arteries. It predominantly presents with symptoms of affection of the external carotid artery branches. Furthermore, the only symptoms can be constitutional. In clinical practice, vasculitides are sometimes considered as paraneoplastic, but no definite association with malignancies has been established and the mechanisms are still debated. The gold standard for diagnosing giant cell arteritis is a positive temporal artery biopsy, but the results can often be false negative. Additionally, more than half of the patients have aorta and its main branches affected. Considering aforementioned, imaging studies are essential in confirming large-vessel vasculitis, amongst which is highly sensitive PET/CT. We present the case of a 70-year-old female patient with constitutional symptoms and elevated sedimentation rate. After extensive diagnostic tests, she was admitted to our Rheumatology unit. Aortitis of the abdominal aorta has been confirmed by PET/CT and after the introduction of glucocorticoids the disease soon went into clinical and laboratory remission. Shortly after aortitis has been diagnosed, lung carcinoma was revealed of which the patient died. At the time of the comprehensive diagnostics, there was no reasonable doubt for underlying malignoma. To the best of our knowledge, there are no recent publications concerning giant cell arteritis and neoplastic processes in the context of up-to-date non-invasive diagnostic methods (i.e. PET/CT). In the light of previous research results, we underline that the sensitivity of PET/CT is not satisfactory when estimating cancer dissemination in non-enlarged lymph nodes and that its value can at times be overestimated.

The association between fatty liver and metabolic syndrome (MS) is well documented and widely accepted. Cirrhosis due to nonalcoholic steatohepatitis (NASH) is currently the second most common indication for liver transplant with increasing incidence. Gastroenterologists/hepathologists and primary care physicians have more questions than answers regarding the NAFLD. The most common questions are which NAFLD patients have a risk of progression to NASH, fibrosis, cirrhosis and hepa- tocellular carcinoma, and which patients with NAFLD have a need for liver biopsy. In addition, a number of non-invasive diagnostic methods in the approach to the patient with NAFLD are investigated. How to approach these patients in routine clinical practice, is more of an art than a science at this time. In this article we will try to provide more recent recommenda- tions of how to approach the patients with NAFLD.

AB - Thin-film transistors (TFTs) have received great attention for their use in lightweight, large area, and wearable devices. However, low crystalline materials and inhomogeneous film formation limit the realization of high-quality electrical properties for channels in commercial TFTs, especially for flexible electronics. Here, we report a field-effect TFT fabricated via cross-linking of edge-1T basal 2H MoS2 sheets that are prepared by edge functional exfoliation of bulk MoS2 with soft organic exfoliation reagents. For edge functional exfoliation, the electrophilic 4-carboxy-benzenediazonium used as the soft organic reagent attacks the nucleophilic thiolates exposed at the edge of the bulk MoS2 with the help of an amine catalyst, resulting in 1T edge-functional HOOC-benzene-2H basal MoS2 nanosheets (e-MoS2). The cross-linking via hydrogen bonding of the negatively charged HOOC of the e-MoS2 sheets with the help of a cationic polymer, polydiallyldimethylammonium chloride, results in a good film formation for a channel of the solution processing TFT. The TFT exhibits an extremely high mobility of 170 cm2/(V s) at 1 V (on/off ratio of 106) on SiO2/Si substrate and also a high mobility of 36.34 cm2/(V s) (on/off ratio of 103) on PDMS/PET substrate.

AB - Superhydrophobicity, the enhanced hydrophobicity of surfaces decorated with textures of suitable size, is associated with a layer of gas trapped within surface roughness. The reduced liquid/solid contact makes superhydrophobicity attractive for many technological applications. This gas layer, however, can break down with the liquid completely wetting the surface. Experiments have shown that the recovery of the "suspended" superhydrophobic state from the wet one is difficult. Self-recovery-the spontaneous restoring of the gas layer at ambient conditions-is one of the dreams of research in superhydrophobicity as it would allow to overcome the fragility of superhydrophobicity. In this work we have performed a theoretical investigation of the wetting and recovery processes on a set of surfaces characterized by textures of different dimensions and morphology in order to elucidate the optimal parameters for avoiding wetting and achieving self-recovery. Results show that texture size in the nanometer range is a necessary but not sufficient condition for self-recovery: the geometry plays a crucial role, nanopillars prevent self-recovery, while surfaces with square pores exhibit self-recovery even at large positive pressures. However, the optimal morphology for self-recovery, the square pore, is suboptimal for the functional properties of the surface, for example, high slippage. Our calculations show that these two properties are related to regions of the texture separated in space: self-recovery is controlled by the characteristics of the bottom surface, while wetting and slip are controlled by the cavity mouth. We thus propose a modular design strategy which combines self-recovery and good functional properties: Square pores surmounted by ridges achieve self-recovery even at 2 MPa and have a very small liquid/solid contact area. The macroscopic calculations, which allowed us to efficiently devise design criteria, have been validated by atomistic simulations, with the optimal texture showing self-recovery on atomic time scales, tau ~ 2 ns. PMID- 29182847 TI - NRPS-Derived Isoquinolines and Lipopetides Mediate Antagonism between Plant Pathogenic Fungi and Bacteria. AB - Bacterial-fungal interactions are presumed to be mediated chiefly by small molecule signals; however, little is known about the signaling networks that regulate antagonistic relationships between pathogens. Here, we show that the ralstonins, lipopeptides produced by the plant pathogenic bacteria Ralstonia solanacearum, interfere with germination of the plant-pathogenic fungus Aspergillus flavus by down-regulating expression of a cryptic biosynthetic gene cluster (BGC), named imq. Comparative metabolomic analysis of overexpression strains of the transcription factor ImqK revealed imq-dependent production of a family of tripeptide-derived alkaloids, the imizoquins. These alkaloids are produced via a nonribosomal peptide synthetase- (NRPS-)derived tripeptide and contain an unprecedented tricyclic imidazo[2,1-a]isoquinoline ring system. We show that the imizoquins serve a protective role against oxidative stress that is essential for normal A. flavus germination. Supplementation of purified imizoquins restored wildtype germination to a DeltaimqK A. flavus strain and protected the fungus from ROS damage. Whereas the bacterial ralstonins retarded A. flavus germination and suppressed expression of the imq cluster, the fungal imizoquins in turn suppressed growth of R. solanacearum. We suggest such reciprocal small-molecule-mediated antagonism is a common feature in microbial encounters affecting pathogenicity and survival of the involved species. PMID- 29182849 TI - Ion Trapping of Amines in Protozoa: A Novel Removal Mechanism for Micropollutants in Activated Sludge. AB - To optimize removal of organic micropollutants from the water cycle, understanding the processes during activated sludge treatment is essential. In this study, we hypothesize that aliphatic amines, which are highly abundant among organic micropollutants, are partly removed from the water phase in activated sludge through ion trapping in protozoa. In ion trapping, which has been extensively investigated in medical research, the neutral species of amine containing compounds diffuse through the cell membrane and further into acidic vesicles present in eukaryotic cells such as protozoa. There they become trapped because diffusion of the positively charged species formed in the acidic vesicles is strongly hindered. We tested our hypothesis with two experiments. First, we studied the distribution of the fluorescent amine acridine orange in activated sludge by confocal fluorescence imaging. We observed intense fluorescence in distinct compartments of the protozoa, but not in the bacterial biomass. Second, we investigated the distribution of 12 amine-containing and eight control micropollutants in both regular activated sludge and sludge where the protozoa had been inactivated. In contrast to most control compounds, the amine-containing micropollutants displayed a distinctly different behavior in the noninhibited sludge compared to the inhibited one: (i) more removal from the liquid phase; (ii) deviation from first-order kinetics for the removal from the liquid phase; and (iii) higher amounts in the solid phase. These results provide strong evidence that ion trapping in protozoa occurs and that it is an important removal mechanism for amine-containing micropollutants in batch experiments with activated sludge that has so far gone unnoticed. We expect that our findings will trigger further investigations on the importance of this process in full-scale wastewater treatment systems, including its relevance for accumulation of ammonium.

AB - Transition-metal sulfides (TMSs) are suggested as promising electrode materials for electrochemical pseudocapacitors and lithium- and sodium-ion batteries; however, they typically involve mixed composites or conventionally stoichiometric TMSs (such as NiCo2S4 and Ni2CoS4). Herein we demonstrate a preparation of solid solution sulfide (Ni0.7Co0.3)S2 supported on three-dimensional graphene aerogel (3DGA) via a sulfuration of NiCo-layered double hydroxide (NiCo-LDH) precursor/3DGA. The electrochemical tests show that the (Ni0.7Co0.3)S2/3DGA electrode exhibits a capacitance of 2165 F g-1 at 1 A g-1, 2055 F g-1 at 2 A g-1, and 1478 F g-1 at 10 A g-1; preserves 78.5% capacitance retention upon 1000 cycles for pseudocapacitors; and in particular, possesses a relatively high charge capacity of 388.7 mA h g-1 after 50 cycles at 100 mA g-1 as anode nanomaterials for sodium-ion batteries. Furthermore, the electrochemical performances are readily tuned by varying the cationic type of the tunable LDH precursors to prepare different solid-solution sulfides, such as (Ni0.7Fe0.3)S2/3DGA and (Co0.7Fe0.3)S2/3DGA. Our results show that engineering LDH precursors can offer an alternative for preparing diverse transition-metal sulfides for energy storage. PMID- 29182851 TI - Valley Polarization of Trions and Magnetoresistance in Heterostructures of MoS2 and Yttrium Iron Garnet. AB - Manipulation of spin degree of freedom (DOF) of electrons is the fundamental aspect of spintronic and valleytronic devices. Two-dimensional transition metal dichalcogenides (2D TMDCs) exhibit an emerging valley pseudospin, in which spin up (-down) electrons are distributed in a +K (-K) valley. This valley polarization gives a DOF for spintronic and valleytronic devices. Recently, magnetic exchange interactions between graphene and magnetic insulator yttrium iron garnet (YIG) have been exploited. However, the physics of 2D TMDCs with YIG have not been shown before. Here we demonstrate strong many-body effects in a heterostructure geometry comprising a MoS2 monolayer and YIG. High-order trions are directly identified by mapping absorption and photoluminescence at 12 K. The electron doping density is up to ~1013 cm-2, resulting in a large splitting of ~40 meV between trions and excitons. The trions exhibit a high circular polarization of ~80% under optical pumping by circularly polarized light at ~1.96 eV; it is confirmed experimentally that both phonon scattering and electron-hole exchange interaction contribute to the valley depolarization with temperature; importantly, a magnetoresistance (MR) behavior in the MoS2 monolayer was observed, and a giant MR ratio of ~30% is achieved, which is 1 order of magnitude larger than the reported ratio in MoS2/CoFe2O4 heterostructures. Our experimental results confirm that the giant MR behaviors are attributed to the interfacial spin accumulation due to YIG substrates. Our work provides an insight into spin manipulation in a heterostructure of monolayer materials and magnetic substrates. PMID- 29182852 TI - Multilayer Graphene-WSe2 Heterostructures for WSe2 Transistors. AB - Two-dimensional (2D) materials are drawing growing attention for next-generation electronics and optoelectronics owing to its atomic thickness and unique physical properties. One of the challenges posed by 2D materials is the large source/drain (S/D) series resistance due to their thinness, which may be resolved by thickening the source and drain regions. Recently explored lateral graphene-MoS21 3 and graphene-WS21,4 heterostructures shed light on resolving the mentioned issues owing to their superior ohmic contact behaviors. However, recently reported field-effect transistors (FETs) based on graphene-TMD heterostructures have only shown n-type characteristics. The lack of p-type transistor limits their applications in complementary metal-oxide semiconductor electronics. In this work, we demonstrate p-type FETs based on graphene-WSe2 lateral heterojunctions grown with the scalable CVD technique. Few-layer WSe2 is overlapped with the multilayer graphene (MLG) at MLG-WSe2 junctions such that the contact resistance is reduced. Importantly, the few-layer WSe2 only forms at the junction region while the channel is still maintained as a WSe2 monolayer for transistor operation. Furthermore, by imposing doping to graphene S/D, 2 orders of magnitude enhancement in Ion/Ioff ratio to ~108 and the unipolar p-type characteristics are obtained regardless of the work function of the metal in ambient air condition. The MLG is proposed to serve as a 2D version of emerging raised source/drain approach in electronics. PMID- 29182853 TI - Role of Precursor-Conversion Chemistry in the Crystal-Phase Control of Catalytically Grown Colloidal Semiconductor Quantum Wires. AB - Crystal-phase control is one of the most challenging problems in nanowire growth. We demonstrate that, in the solution-phase catalyzed growth of colloidal cadmium telluride (CdTe) quantum wires (QWs), the crystal phase can be controlled by manipulating the reaction chemistry of the Cd precursors and tri-n-octylphosphine telluride (TOPTe) to favor the production of either a CdTe solute or Te, which consequently determines the composition and (liquid or solid) state of the BixCdyTez catalyst nanoparticles. Growth of single-phase (e.g., wurtzite) QWs is achieved only from solid catalysts (y ? z) that enable the solution-solid-solid growth of the QWs, whereas the liquid catalysts (y ~ z) fulfill the solution liquid-solid growth of the polytypic QWs. Factors that affect the precursor conversion chemistry are systematically accounted for, which are correlated with a kinetic study of the composition and state of the catalyst nanoparticles to understand the mechanism. This work reveals the role of the precursor-reaction chemistry in the crystal-phase control of catalytically grown colloidal QWs, opening the possibility of growing phase-pure QWs of other compositions. PMID- 29182855 TI - Bacterial Adhesion to Ultrafiltration Membranes: Role of Hydrophilicity, Natural Organic Matter, and Cell-Surface Macromolecules. AB - Insight into the mechanisms underlying bacterial adhesion is critical to the formulation of membrane biofouling control strategies. Using AFM-based single cell force spectroscopy, we investigated the interaction between Pseudomonas fluorescens, a biofilm-forming bacterium, and polysulfone (PSF) ultrafiltration (UF) membranes to unravel the mechanisms underlying early stage membrane biofouling. We show that hydrophilic polydopamine (PDA) coatings decrease bacterial adhesion forces at short bacterium-membrane contact times. Further, we find that adhesion forces are weakened by the presence of natural organic matter (NOM) conditioning films, owing to the hydrophilicity of NOM. Investigation of the effect of adhesion contact time revealed that PDA coatings are less effective at preventing bioadhesion when the contact time is prolonged to 2-5 s, or when the membranes are exposed to bacterial suspensions under stirring. These results therefore challenge the notion that simple hydrophilic surface coatings are effective as a biofouling control strategy. Finally, we present evidence that adhesion to the UF membrane surface is mediated by cell-surface macromolecules (likely to be outer membrane proteins and pili) which, upon contacting the membrane, undergo surface-induced unfolding. PMID- 29182854 TI - Identification of a Functionally Unique Family of Penicillin-Binding Proteins. AB - Penicillin-binding proteins (PBPs) are enzymes involved in the assembly of the bacterial cell wall, a major target for antibiotics. These proteins are classified by mass into high-molecular-weight PBPs, which are transpeptidases that form peptidoglycan cross-links, and low-molecular-weight PBPs, which are typically hydrolases. We report a functionally unique family of low-molecular weight PBPs that act as transpeptidases rather than hydrolases, but they do not cross-link peptidoglycan. We show that these PBPs can exchange d-amino acids bearing chemical tags or affinity handles into peptidoglycan precursors, including Lipid II, enabling biochemical studies of proteins involved in cell wall assembly. We report that, in two organisms, the PBPs incorporate lysine into cellular peptidoglycan and that, further, the PBPs have the unprecedented ability to transfer the primary epsilon-amine of lysine to peptidoglycan. PMID- 29182856 TI - Direct Observation of Photoinduced Ultrafast Generation of Singlet and Triplet Quinone Methides in Aqueous Solutions and Insight into the Roles of Acidic and Basic Sites in Quinone Methide Formation. AB - Femtosecond time-resolved transient absorption spectroscopy experiments and density functional theory computations were done for a mechanistic investigation of 3-(1-phenylvinyl)phenol (1) and 3-hydroxybenzophenone (2) in selected solvents. Both compounds went through an intersystem crossing (ISC) to form the triplet excited states Tpipi* and Tnpi* in acetonitrile but behave differently in neutral aqueous solutions, in which a triplet excited state proton transfer (ESPT) induced by the ISC process is also proposed for 2 but a singlet ESPT without ISC is proposed for 1, leading to the production of the triplet quinone methide (QM) and the singlet excited QM species respectively in these two systems. The triplet QM then underwent an ISC process to form an unstable ground state intermediate which soon returned to its starting material 2. However, the singlet excited state QM went through an internal conversion process to the ground state QM followed by the formation of its final product in an irreversible manner. These differences are thought to be derived from the slow vinyl C-C rotation and the moderate basicity of the vinyl C atom in 1 as compared with the fast C-O rotation and the greater basicity of the carbonyl O atom of 2 after photoexcitation. This can account for the experimental results in the literature that the aromatic vinyl compounds undergo efficient singlet excited state photochemical reactions while the aromatic carbonyl compounds prefer triplet photochemical reactions under aqueous conditions. These results have fundamental and significant implications for understanding of the ESPT reactivity in general, as well as for the design of molecules for efficient QM formation in aqueous media with potential applications in cancer phototherapy.

AB - Robust catechol coatings for enhanced moisture tolerance were produced in one step by direct reaction of Hong Kong University of Science and Technology (HKUST) with synthetic catechols. We ascribe the rapid formation of homogeneous coatings around the metal-organic framework particles to the biomimetic catalytic activity of Cu(II) dimers in the external surface of the crystals. Use of fluorinated catechols results in hydrophobic, permeable coatings that protect HKUST from water degradation while retaining close to 100% of its original sorption capacity. PMID- 29182858 TI - Cell-free DNA: A Neglected Source for Antibiotic Resistance Genes Spreading from WWTPs. AB - Cell-associated ARGs in wastewater treatment plants (WWTPs) has been concerned, however, cell-free ARGs in WWTPs was rarely studied. In this study, the abundances of four representative ARGs, sulII, tetC, blaPSE-1, and ermB, in a large municipal WWTP were investigated in both cell-associated and cell-free fractions. Cell-associated ARGs was the dominant ARGs fraction in the raw wastewater. After biological treatment, sludge settling, membrane filtration, and disinfection, cell-associated ARGs were substantially reduced, though the ratios of ARG/16S rRNA gene were increased with disinfection. Cell-free ARGs persisted in the WWTP with a removal of 0.36 log to 2.68 logs, which was much lower than the removal of cell-associated ARGs (3.21 logs to 4.14 logs). Therefore, the abundance ratio of cell-free ARGs to cell-associated ARGs increased from 0.04 1.59% to 2.00-1895.08% along the treatment processes. After 25-day-storage, cell free ARGs in both biological effluent and disinfection effluent increased by 0.14 log to 1.99 logs and 0.12 log to 1.77 logs respectively, reflecting the persistence and low decay rate of cell-free ARGs in the discharge water. Therefore, cell-free ARGs might be a kind of important but previously neglected pollutant from WWTPs, which added potential risks to the effluent receiving environments. PMID- 29182859 TI - High Circular Polarization of Electroluminescence Achieved via Self-Assembly of a Light-Emitting Chiral Conjugated Polymer into Multidomain Cholesteric Films. AB - We demonstrate a facile route to obtain high and broad-band circular polarization of electroluminescence in single-layer polymer OLEDs. As a light-emitting material we use a donor-acceptor polyfluorene with enantiomerically pure chiral side-chains. We show that upon thermal annealing the polymer self-assembles into a multidomain cholesteric film. By varying the thickness of the polymer emitting layer, we achieve high levels of circular polarization of electroluminescence (up to 40% excess of right-handed polarization), which are the highest reported for polymer OLEDs not using chiral dopants or alignment layers. Mueller matrix ellipsometry shows strong optical anisotropies in the film, indicating that the circular polarization of luminescence arises mainly after the photon has been generated, through selective scattering and birefringence correlated in the direction of the initial linear polarization of the photon. Our work demonstrates that chirally substituted conjugated polymers can combine photonic and semiconducting properties in advanced optoelectronic devices. PMID- 29182861 TI - Synthesis and Electronic Structures of Heavy Lanthanide Metallocenium Cations. AB - The origin of 60 K magnetic hysteresis in the dysprosocenium complex [Dy(Cpttt)2][B(C6F5)4] (Cpttt = C5H2tBu3-1,2,4, 1-Dy) remains mysterious, thus we envisaged that analysis of a series of [Ln(Cpttt)2]+ (Ln = lanthanide) cations could shed light on these properties. Herein we report the synthesis and physical characterization of a family of isolated [Ln(Cpttt)2]+ cations (1-Ln; Ln = Gd, Ho, Er, Tm, Yb, Lu), synthesized by halide abstraction of [Ln(Cpttt)2(Cl)] (2-Ln; Ln = Gd, Ho, Er, Tm, Yb, Lu). Complexes within the two families 1-Ln and 2-Ln are isostructural and display pseudo-linear and pseudo-trigonal crystal fields, respectively. This results in archetypal electronic structures, determined with CASSCF-SO calculations and confirmed with SQUID magnetometry and EPR spectroscopy, showing easy-axis or easy-plane magnetic anisotropy depending on the choice of Ln ion. Study of their magnetic relaxation dynamics reveals that 1 Ho also exhibits an anomalously low Raman exponent similar to 1-Dy, both being distinct from the larger and more regular Raman exponents for 2-Dy, 2-Er, and 2 Yb. This suggests that low Raman exponents arise from the unique spin-phonon coupling of isolated [Ln(Cpttt)2]+ cations. Crucially, this highlights a direct connection between ligand coordination modes and spin-phonon coupling, and therefore we propose that the exclusive presence of multihapto ligands in 1-Dy is the origin of its remarkable magnetic properties. Controlling the spin-phonon coupling through ligand design thus appears vital for realizing the next generation of high-temperature single-molecule magnets. PMID- 29182860 TI - Investigating Pharmacological Targeting of G-Quadruplexes in the Human Malaria Parasite. AB - The unique occurrence of G-quadruplexes in the AT-rich genome of human malaria parasite Plasmodium falciparum provides hints about their critical roles in parasite survival, pathogenesis, and host immune evasion. An intriguing question is whether these noncanonical structures can serve as molecular targets for small molecule-based interventions against malaria. In this study, we have investigated the pharmacological targeting of G-quadruplexes for parasite inhibition. We observed that bisquinolinium derivatives of 1,8-naphthyridine and pyridine affected the stability and molecular recognition properties of G-quadruplexes in telomeric and subtelomeric regions in P. falciparum. Parasite inhibition and cytotoxicity assays revealed that these ligands effectively inhibit parasite growth with minimal toxic effects in human cells. G-quadruplex interacting ligands caused degeneration and shortening of parasite telomeres. Ligand-induced perturbations in telomere homeostasis also affected transcriptional state of the subtelomeric region harboring antigenic variation genes. Taken together, our results suggest that quadruplex-ligand interaction disturbs telomeric/subtelomeric chromatin organization and induces DNA damage that consequently leads to parasite death. Our findings also draw attention to the striking differences in telomere dynamics in the protozoan parasite and human host that can be exploited for selective targeting of the telomeric quadruplex of the parasite as a potential antimalarial strategy. PMID- 29182862 TI - Inhibition of Mammalian 15-Lipoxygenase by Three Ebselen-like Drugs. A QM/MM and MM/PBSA Comparative Study. AB - Ebselen is a potent competitive inhibitor of the active form of rabbit 15 lipoxygenase, an enzyme involved in many inflammatory diseases. Light-induced Z to-E isomerization of the ebselen-like 2-(3-benzylidene)-3-oxo-2,3 dihydrobenzo[b]thiophene-7-carboxylic acid methyl ester (BODTCM) molecule was used to convert the weak (Z)-BOTDCM inhibitor into the (E)-isomer with much higher inhibitory capacity. In this study, the binding modes of ebselen, (E) BOTDCM and (Z)-BOTDCM, have been analyzed to provide molecular insights on the inhibitory potency of ebselen and on the geometric-isomer specificity of (E)- and (Z)-BOTDCM inhibitors. The inhibitor-enzyme structures obtained from docking and molecular dynamics simulations as well as from QM/MM calculations show that the inhibitor molecules are not coordinated to the nonheme iron in the active site. Thermal motion allows ebselen and (E)-BOTDCM to visit a wide range of the configurational space competing with the polyunsaturated fatty acid for binding at the active site. Both molecules present similar MM/PBSA binding free energies. The energy penalty for the bigger geometric deformation undergone by (E)-BODTCM would explain its lower inhibitor potency. The (Z)-isomer is the weakest inhibitor because thermal motion moves it to a region very far from the first coordination sphere of Fe, where it could not compete with the fatty acid substrate. PMID- 29182863 TI - The Atmospheric Oxidation of HONO by OH, Cl, and ClO Radicals. AB - The atmospheric oxidation of nitrous acid by hydroxyl radical, chlorine atom, and chlorine monoxide radical was investigated with high-level theoretical methods. Nitrous acid has two conformers (cis and trans), and we found a reaction path for the oxidation of each of these conformers with the radicals considered. In all cases, the oxidation of the cis conformer is much more favorable than the oxidation of the trans conformer. Interestingly all transition states in these oxidation processes follow a proton-coupled electron-transfer mechanism. Our computed rate constant at 298 K for the reaction of cis-HONO + .OH is 4.83 * 10 12 cm3 molecule-1 s-1, in excellent agreement with their experimental values (4.85 * 10-12 and 6.48 * 10-12 cm3 molecule-1 s-1). For the trans-HONO + .OH reaction our calculated rate constant at 298 K is 9.05 * 10-18 cm3 molecule-1 s 1, and we computed an effective rate constant for the oxidation of the whole nitrous acid by hydroxyl radical of 1.81 * 10-12 cm3 molecule-1 s-1. For the oxidation of nitrous acid by chlorine atom we predict greater rate constants (7.38 * 10-11, 3.33 * 10-15, and 2.76 * 10-11 cm3 molecule-1 s-1, for the cis and trans conformers and for the whole HONO), these results suggesting that this reaction should contribute to the tropospheric oxidation of nitrous acid, especially in marine boundary areas, and to the formation of tropospheric ozone. For the oxidation of nitrous acid by chlorine monoxide we predict rate constants roughly 6 orders of magnitude smaller than the oxidation by chlorine atom, and therefore we consider that this process should play a minor role in the troposphere. PMID- 29182864 TI - Electronic Properties and Electroluminescent OLED Performance of Panchromatic Emissive N-Aryl-2,3-naphthalimides. AB - This report investigates the excited-state properties of a series of N-aryl-2,3 naphthalimides along with their fabrication into OLEDs and electroluminescence measurements. The N-aryl-2,3-NIs substituted specifically with chloro, fluoro, and methoxy substituents were chosen because of their unique propensity to display two emission bands or panchromatic fluorescence. Using the Lippert-Mataga analysis along with TD-DFT calculations, the excited states were determined to be n,pi* and pi,pi*. The TD-DFT calculations on the geometries of the excited states indicate that the excited state shows a planar structure. The origin of both the short wavelength (SW) and long wavelength (LW) emission were correlated to specific geometries such that the SW emission originates from an "angled" structure in the excited state, and LW emission originates from an excited state of coplanar structure. All of the dyes investigated readily formed good films under ultrahigh vacuum deposition. The molecular energy levels of these compounds (HOMO and LUMO) were measured with cyclic voltammetry. Band gaps were also measured in both electrochemical and optical methods and indicate that the HOMOs of these fluorophores matched well with the anode (ITO work function), and their LUMOs matched well with the cathode (LiF/Al). To compare photoluminescence of the four dyes with their potential electroluminescence, three OLED devices were designed and fabricated. The electroluminescent spectra of these devices indicate that the panchromatic fluorescence, observed in solution, shifts toward the red in the solid-state. A plausible explanation appears to stem from an inability to inject electrons to the higher LUMO+1 orbitals; a process observed in the solution phase. Hence, the short wavelength fluorescence peak, a key component to panchromatic luminescence disappears in the OLED device. The observed EL spectrum from these smaller heteroatomic architectures is on par if not more broadly emissive than rubrene (5,6,11,12-tetraphenyltetracene), a red-colored C42H28 polycyclic aromatic hydrocarbon, that displays an orange-color EL.

AB - The rate of the methylenecyclopropane rearrangement is enhanced by an alkyne Co2(CO)6 complex bonded to the para position of a benzene ring. This is explained by a stabilizing effect on the transition state leading to the biradical intermediate. Computational studies indicate that the benzylic-type biradical intermediate is stabilized by a delocalization mechanism, where spin is delocalized onto the two cobalt atoms. Silver cation also enhances the rate of the methylenecyclopropane rearrangement. Computational studies suggest that silver cation can also stabilize a benzylic radical by spin delocalization involving silver. In the case of the silver-promoted reactions, the rate enhancements in a series of aryl-substituted methylenecyclopropanes correlate with sigma+ values. The question remains open as to whether the silver-catalyzed methylenecyclopropane rearrangement proceeds via an argento-stabilized biradical or whether the reaction involves an argento-substituted allylic cation.

AB - The combination of copper-free click chemistry with metabolic labeling offers new opportunities in drug delivery. The objective of this study was to determine whether cubosomes functionalized with azide or dibenzocyclooctyne (DBCO) groups are able to undergo copper-free click chemistry with a strained cyclooctyne or azide, respectively. Phytantriol-based cubosomes were functionalized using phospholipids bearing an azide or DBCO group. The modified cubosome dispersions were characterized using dynamic light scattering, cryo-TEM, and small-angle X ray scattering. The efficiency of "clickability" was assessed by reacting the cubosomes with a complementary dye and determining bound and unbound dye via size exclusion chromatography. The clickable cubosomes reacted specifically and efficiently with a click-Cy5 dye with minor changes to the size, shape, and structure of the cubosomes. This indicates that cubosomes can retain their unique internal structure while participating in copper-free click chemistry. This proof of concept study paves the way for the use of copper-free click chemistry and metabolic labeling with cubosomes for targeted drug delivery and imaging.

AB - Bauxite residue is a high volume byproduct of alumina manufacture which is commonly disposed of in purpose-built bauxite residue disposal areas (BRDAs). Natural waters interacting with bauxite residue are characteristically highly alkaline, and have elevated concentrations of Na, Al, and other trace metals. Rehabilitation of BRDAs is therefore often costly and resource/infrastructure intensive. Data is presented from three neighboring plots of bauxite residue that was deposited 20 years ago. One plot was amended 16 years ago with process sand, organic matter, gypsum, and seeded (fully treated), another plot was amended 16 years ago with process sand, organic matter, and seeded (partially treated), and a third plot was left untreated. These surface treatments lower alkalinity and salinity, and thus produce a substrate more suitable for biological colonisation from seeding. The reduction of pH leads to much lower Al, V, and As mobility in the actively treated residue and the beneficial effects of treatment extend passively 20-30 cm below the depth of the original amendment. These positive rehabilitation effects are maintained after 2 decades due to the presence of an active and resilient biological community. This treatment may provide a lower cost solution to BRDA end of use closure plans and orphaned BRDA rehabilitation.

AB - The present work surveys the performance of various widely used density functional theory exchange-correlation (xc) functionals in describing observable surface properties of a total of 27 transition metals with face-centered cubic (fcc), body-centered cubic (bcc), or hexagonal close-packed (hcp) crystallographic structures. A total of 81 low Miller index surfaces were considered employing slab models. Exemplary xc functionals within the three first rungs of Jacob's ladder were considered, including the Vosko-Wilk-Nusair xc functional within the local density approximation, the Perdew-Burke-Ernzerhof (PBE) functional within the generalized gradient approximation (GGA), and the Tao Perdew-Staroverov-Scuseria functional as a meta-GGA functional. Hybrids were excluded in the survey because they are known to fail in properly describing metallic systems. In addition, two variants of PBE were considered, PBE adapted for solids (PBEsol) and revised PBE (RPBE), aimed at improving adsorption energies. Interlayer atomic distances, surface energies, and surface work functions were chosen as the scrutinized properties. A comparison with available experimental data, including single-crystal and polycrystalline values, shows that no xc functional is best at describing all of the surface properties. However, in statistical mean terms the PBEsol xc functional is advised, while PBE is recommended when considering both bulk and surface properties. On the basis of the present results, a discussion of adapting GGA functionals to the treatment of metallic surfaces in an alternative way to meta-GGA or hybrids is provided.

AB - The effects of salts on the stability of amorphous sucrose and its crystallization in different environments were investigated. Chloride (LiCl, NaCl, KCl, MgCl2, CaCl2, CuCl2, FeCl2, FeCl3, and AlCl3) and sulfate salts with the same cations (Na2SO4, K2SO4, MgSO4, CuSO4, Fe(II)SO4, and Fe(III)SO4) were studied. Samples (sucrose controls and sucrose:salt 1:0.1 molar ratios) were lyophilized, stored in controlled temperature and relative humidity (RH) conditions, and monitored for one month using X-ray diffraction. Samples were also analyzed by differential scanning calorimetry, microscopy, and moisture sorption techniques. All lyophiles were initially amorphous, but during storage the presence of a salt had a variable impact on sucrose crystallization. While all samples remained amorphous when stored at 11 and 23% RH at 25 degrees C, increasing the RH to 33 and 40% RH resulted in variations in crystallization onset times. The recrystallization time generally followed the order monovalent cations < sucrose < divalent cations < trivalent cations. The presence of a salt typically increased water sorption as compared to sucrose alone when stored at the same RH; however, anticrystallization effects were observed for sucrose combined with salts containing di- and trivalent cations in spite of the increased water content. The cation valency and hydration number played a major role in dictating the impact of the added salt on sucrose crystallization. PMID- 29182870 TI - Catalyst-Controlled Diastereoselective Synthesis of Cyclic Amines via C-H Functionalization. AB - Reliable regio- and stereochemical techniques applicable to nonactivated aliphatic systems remain largely elusive due to the challenges of discriminating between multiple, relatively strong sp3 C-H bonds whose chemical behavior often differ only subtly. Nevertheless, approaches that employ directing groups and/or auxiliaries have emerged, but impose practical restrictions, especially in complex molecule synthesis. This report describes a catalyst-controlled regio- and diastereoselective synthesis of N-unprotected pyrrolidines via dirhodium catalyzed intramolecular nitrene insertion into sp3 C-H bonds. The reaction proceeds at rt without external oxidants, nitrene stabilizing groups, or directing functionality. The insights that emerged from the conformational/stereoselectivity relationships (CSR) between catalysts and substrates provide a framework for rational catalyst design that can accommodate a broader range of aliphatic C-H chemistry.

AB - Contaminated sites pose ecological and human-health risks through exposure to contaminated soil and groundwater. Whereas we can readily locate, monitor, and track contaminants in groundwater, it is harder to perform these tasks in the vadose zone. In this study, tree-core samples were collected at a Superfund site to determine if the sample-collection location around a particular tree could reveal the subsurface location, or direction, of soil and soil-gas contaminant plumes. Contaminant-centroid vectors were calculated from tree-core data to reveal contaminant distributions in directional tree samples at a higher resolution, and vectors were correlated with soil-gas characterization collected using conventional methods. Results clearly demonstrated that directional tree coring around tree trunks can indicate gradients in soil and soil-gas contaminant plumes, and the strength of the correlations were directly proportionate to the magnitude of tree-core concentration gradients (spearman's coefficient of -0.61 and -0.55 in soil and tree-core gradients, respectively). Linear regression indicates agreement between the concentration-centroid vectors is significantly affected by in planta and soil concentration gradients and when concentration centroids in soil are closer to trees. Given the existing link between soil-gas and vapor intrusion, this study also indicates that directional tree coring might be applicable in vapor intrusion assessment.

AB - An efficient synthesis of substituted isocanthines has been achieved using an intramolecular Rh(III)-catalyzed C-H functionalization of alkyne-tethered indoles in the presence of catalytic tris(acetonitrile)pentamethylcyclopentadienylrhodium(III) hexafluoroantimonate and stoichiometric copper(II) acetate. This isocanthine synthesis tolerates a variety of electronically diverse 5- or 6-substituted indoles with N-tethered alkyne coupling partners and can also be extended to pyrrole derivatives for the synthesis of annulated 5-azaindoles. PMID- 29182873 TI - Mechanical Unfolding of Macromolecules Coupled to Bond Dissociation. AB - Single-molecule force spectroscopy has become a powerful tool to investigate molecular mechanisms in biophysics and materials science. In particular, the new field of polymer mechanochemistry has emerged to study how tension may induce chemical reactions in a macromolecule. A rich example is the mechanical unfolding of the metalloprotein rubredoxin coupled to dissociation of iron-sulfur bonds that has recently been studied in detail by atomic force microscopy. Here, we present a simple molecular model composed of a classical all-atom force field description, implicit solvation, and steered molecular dynamics simulation to describe the mechanical properties and mechanism of forced unfolding coupled to covalent bond dissociation of macromolecules. We apply this model and test it extensively to simulate forced rubredoxin unfolding, and we dissect the sensitivity of the calculated mechanical properties with model parameters. The model provides a detailed molecular explanation of experimental observables such as force-extension profiles and contour length increments. Changing the points of force application along the macromolecule results in different unfolding mechanisms, characterized by disruption of hydrogen bonds and secondary protein structure, and determines the degree of solvent access to the reactive center. We expect that this molecular model will be broadly applicable to simulate (bio)polymer mechanochemistry. PMID- 29182874 TI - Revisiting Nitrogen Species in Covalent Triazine Frameworks. AB - Covalent triazine frameworks (CTFs) are porous organic materials promising for applications in catalysis and separation due to their high stability, adjustable porosity, and intrinsic nitrogen functionalities. CTFs are prepared by ionothermal trimerization of aromatic nitriles; however, multiple side reactions also occur under synthesis conditions, and their influence on the material properties is still poorly described. Here we report the systematic characterization of nitrogen in CTFs using X-ray photoelectron spectroscopy. With the use of model compounds, we could distinguish several types of nitrogen species. By combining these data with textural properties, we unravel the influence that the reaction temperature, the catalyst, and the monomer structure and composition have on the properties of the resulting CTF materials. PMID- 29182875 TI - Synthesis, Characterization, and Application of Partially Blocked Amine Functionalized Magnetic Nanoparticles. AB - In this study, a novel technique was introduced for selective surface modification of amine-functionalized magnetic nanoparticles. The method was based on alignment of magnetic nanoparticles in an external magnetic field, which resulted in formation of chain-like assemblies in diluted suspensions. The aligned chains were then modified on the surface via reaction of isocyanate species with the particle functionalities. Finally, after removal from the reactor medium, particles with segmented distribution of surface functionalities were achieved. We named these partially blocked amine-functionalized magnetic nanoparticles as "Saturn" nanoparticles. Application of the particles in fabrication of magnetic assemblies was successfully demonstrated. Using methylene diphenyl diisocyanate (MDI) as the bridging agent, structures in different forms such as chains and filaments were produced by the Saturn particles and compared with cross-linked structures of the unmodified amine-functionalized particles. It is expected that this novel nanoparticle with its unique structure will have great potential in assembly fabrication with a variety of applications in biomedical fields. PMID- 29182876 TI - Solid-State Hydrogen-Deuterium Exchange Mass Spectrometry: Correlation of Deuterium Uptake and Long-Term Stability of Lyophilized Monoclonal Antibody Formulations. AB - Solid state hydrogen-deuterium exchange with mass spectrometric analysis (ssHDX MS) has been used to assess protein conformation and matrix interactions in lyophilized solids. ssHDX-MS metrics have been previously correlated to the formation of aggregates of lyophilized myoglobin on storage. Here, ssHDX-MS was applied to lyophilized monoclonal antibody (mAb) formulations and correlated to their long-term stability. After exposing lyophilized samples to D2O(g), the amount of deuterium incorporated at various time points was determined by mass spectrometry for four different lyophilized mAb formulations. Hydrogen-deuterium exchange data were then correlated with mAb aggregation and chemical degradation, which was obtained in stability studies of >2.5 years. Deuterium uptake on ssHDX MS of four lyophilized mAb formulations determined at the initial time point prior to storage in the dry state was directly and strongly correlated with the extent of aggregation and chemical degradation during storage. Other measures of physical and chemical properties of the solids were weakly or poorly correlated with stability. The data demonstrate, for the first time, that ssHDX-MS results are highly correlated with the stability of lyophilized mAb formulations. The findings thus suggest that ssHDX-MS can be used as an early read-out of differences in long-term stability between formulations helping to accelerate formulation screening and selection.

AB - Cesium lead halide (CsPbX3) perovskite nanocrystals (NCs) have demonstrated extremely excellent optical properties and great application potentials in various optoelectronic devices. However, because of the anion exchange, it is difficult to achieve white-light and multicolor emission for practical applications. Herein, we present the successful doping of various lanthanide ions (Ce3+, Sm3+, Eu3+, Tb3+, Dy3+, Er3+, and Yb3+) into the lattices of CsPbCl3 perovskite NCs through a modified hot-injection method. For the lanthanide ions doped perovskite NCs, high photoluminescence quantum yield (QY) and stable and widely tunable multicolor emissions spanning from visible to near-infrared (NIR) regions are successfully obtained. This work indicates that the doped perovskite NCs will inherit most of the unique optical properties of lanthanide ions and deliver them to the perovskite NC host, thus endowing the family of perovskite materials with excellent optical, electric, or magnetic properties. PMID- 29182878 TI - Synthesis, Polymerization, and Assembly of Nanosilica Particles below the Isoelectric Point. AB - The particle growth of silica below the isoelectric point plays a key role in oil well cements, production of silica gels and production of nanosilica by dissolving silicates. In this article, we study the particle growth of silica below the isoelectric point using olivine, a silicate mineral, and sodium silicate solutions as silica sources in acid, where the particle size, soluble silica concentration, specific surface area and gelling time were measured. The size of the primary particles detected by laser light scattering is 3 nm in the experiments with sodium silicate solutions. These particles grow then by aggregation forming linear chains which in time will start to branch. The particle growth follows a quadratic polynomial function and particles as large as 100 and 500 nm are detected in the final stages of experiments using sodium silica solutions and olivine, respectively. Based on these findings, a comprehensive model describing the silica particle development below the isoelectric point is proposed. This model gives fundamental information about the growth mechanism and the properties of silica (e.g., particle size of the primary particles, size of the aggregates) at the different growth stages.

AB - Deep eutectic solvents have been demonstrated to support amphiphile self assembly, providing potential alternatives as structure-directing agents in the synthesis of nanostructures, and drug delivery. Here we have expanded on this recent research to investigate the self-assembly of alkyltrimethylammonium bromide surfactants in choline chloride:malonic acid deep eutectic solvent and mixtures of the solvent with water. Surface tension and small-angle neutron scattering were used to determine the behavior of the amphiphiles. Surfactants were found to remain active in the solvent, and surface tension measurements revealed changes in the behavior of the surfactants with different levels of hydration. Small-angle neutron scattering shows that in this solvent the micelle shape depends on the surfactant chain length, varying from globular micelles (aspect ratio ~2) for short chain surfactants to elongated micelles (aspect ratio ~14) for long chain surfactants even at low surfactant concentration. We suggest that the formation of elongated micelles can be explained through the interaction of the solvent with the surfactant headgroup, since ion-ion interactions between surfactant headgroups and solvent may modify the morphology of the micelles. The presence of water in the deep eutectic solvents promotes an increase in the charge density at the micelle interface and therefore the formation of less elongated, globular micelles.

AB - Lithium-sulfur (Li-S) batteries hold great promise for the applications of high energy density storage. However, the performances of Li-S batteries are restricted by the low electrical conductivity of sulfur and shuttle effect of intermediate polysulfides. Moreover, the areal loading weights of sulfur in previous studies are usually low (around 1-3 mg cm-2) and thus cannot fulfill the requirement for practical deployment. Herein, we report that porous-shell vanadium nitride nanobubbles (VN-NBs) can serve as an efficient sulfur host in Li S batteries, exhibiting remarkable electrochemical performances even with ultrahigh areal sulfur loading weights (5.4-6.8 mg cm-2). The large inner space of VN-NBs can afford a high sulfur content and accommodate the volume expansion, and the high electrical conductivity of VN-NBs ensures the effective utilization and fast redox kinetics of polysulfides. Moreover, VN-NBs present strong chemical affinity/adsorption with polysulfides and thus can efficiently suppress the shuttle effect via both capillary confinement and chemical binding, and promote the fast conversion of polysulfides. Benefiting from the above merits, the Li-S batteries based on sulfur-filled VN-NBs cathodes with 5.4 mg cm-2 sulfur exhibit impressively high areal/specific capacity (5.81 mAh cm-2), superior rate capability (632 mAh g-1 at 5.0 C), and long cycling stability. PMID- 29182881 TI - Highly Fluorescent Silicon Nanocrystals Stabilized in Water Using Quatsomes. AB - Fluorescent silicon (Si) nanocrystals (2.8 nm diameter) were incorporated into surfactant assemblies of cetyltrimethylammonium bromide (CTAB) and cholesterol, called quatsomes. In water, the quatsome-Si nanocrystal assemblies remain fluorescent and well-dispersed for weeks. In contrast to Si nanocrystals, alkanethiol-capped gold (Au) nanocrystals do not form stable dispersions in water with quatsomes. Cryogenic transmission electron microscopy (cryo-TEM) confirmed that the Si nanocrystal-quatsome structures do not change over the course of several weeks. The long-term stability of the Si nanocrystal-quatsome assemblies, their fluorescence, and biocompatibility makes them attractive candidates for medical applications.

To achieve this aim, more stakeholders in the community residents, elected officials, community-based nonprofits, law enforcement, and schools-need to be engaged in addressing the health challenges in our communities. Moreover, all community stakeholders have to think and act "upstream" by addressing the social determinants of health in their communities.

AB - BACKGROUND: The 17-item Iowa Infant Feeding Attitude Scale (IIFAS) has been widely used to assess maternal attitudes toward infant feeding and to predict breastfeeding intention. The IIFAS has been validated among prenatal women located in Newfoundland and Labrador in Canada, although its length may prove challenging to complete in a clinical setting. Research aim: The authors aimed to reduce the number of items from the original 17-item IIFAS scale while maintaining reliability and validity. METHODS: A nonexperimental cross-sectional design was used among 1,283 women in their third trimester residing in Newfoundland and Labrador. Data were collected from August 2011 to June 2016. An exploratory factor analysis using principal component analysis was performed to explore the underlying structure of the IIFAS. The internal consistency of both the 17-item and reduced version was assessed using Cronbach's alpha and item total correlation. The area under the curve and linear regression model were used to assess predictive validity of intention to breastfeed. RESULTS: Our findings revealed that a 13-item IIFAS (Cronbach's alpha = .870) had relatively similar internal consistency to the original IIFAS (Cronbach's alpha = .868). Three themes were extracted from the factor analysis, resulting in the removal of four items. The reduced scale demonstrated an excellent ability to predict breastfeeding intention (area under the curve = 0.914). CONCLUSION: The reduced 13-item version of the IIFAS is a psychometrically sound instrument that maintains its accuracy and validity when measuring maternal feeding attitudes during pregnancy and can be more time efficient in clinical settings compared with the 17-item IIFAS.

AB - The Centers for Disease Control and Prevention (CDC) recommended in 2006 that sexually active gay, bisexual, and other men who have sex with men (MSM) be screened for human immunodeficiency virus (HIV) at least annually. A workgroup comprising CDC and external experts conducted a systematic review of the literature, including benefits, harms, acceptability, and feasibility of annual versus more frequent screening among MSM, to determine whether evidence was sufficient to change the current recommendation. Four consultations with managers of public and nonprofit HIV testing programs, clinics, and mathematical modeling experts were conducted to provide input on the programmatic and scientific evidence. Mathematical models predicted that more frequent than annual screening of MSM could prevent some new HIV infections and would be more cost-effective than annual screening, but this evidence was considered insufficient due to study design. Evidence supports CDC's current recommendation that sexually active MSM be screened at least annually. However, some MSM might benefit from more frequent screening. Future research should evaluate which MSM subpopulations would benefit most from more frequent HIV screening. PMID- 29182895 TI - Efficacy of downhill running training for improving muscular and aerobic performances. AB - This study investigated effects of downhill (DR) versus level (LR) running training on various muscular and aerobic performances. Eighteen healthy young males conducted either DR (DR group (DRG), n = 10: -10% slope) or LR (LR group (LRG), n = 8) training at a target heart rate (HR) associated with lactate threshold (LT) for 20 min.session-1, 3 sessions.week-1, for 5 weeks. Before and after the interventions, the following variables were measured: knee extension torque (-150, -30, 0, 30, 150 degrees .s-1), leg extension power (simultaneous hip and knee extension: 0.8 m.s-1), squat and countermovement jump height, rebound jump index (jump height.contact time-1), 20-m linear sprint and change-of direction (Pro-agility and V-cut tests) time, and aerobic capacity (maximal oxygen uptake, energy cost at LT, and velocity at maximal oxygen uptake and LT) on a level surface. Throughout the training sessions, HR during running did not differ between the groups (DRG: 77.7% +/- 4.6% vs LRG: 76.4% +/- 4.6% of maximal HR; average across all sessions), while velocity was significantly higher for DRG (14.5 +/- 1.1 vs 12.0 +/- 1.9 km.h-1). After the training, DRG significantly improved knee extension torque at all angular velocities (9%-24%) and change-of direction time for both tests (2%-3%), with no changes in other parameters. LRG significantly improved maximal oxygen uptake (5%), energy cost at LT (3%), and velocity at maximal oxygen uptake (7%), without changes in others. These results suggest that DR training has a greater potential to improve the knee extension strength and change-of-direction ability, but has little effect on the aerobic capacity, compared with HR-matched LR training.

Report from a single center and systematic review of literature. AB - A systematic bibliographic research concerning patients operated on for SBS was performed: inclusion criteria were adult age, reconnection surgery and SBS < 100 cm. Autologous gastrointestinal reconstruction represented an exclusion criteria. The outcomes of interest were the rate of total parenteral nutrition (TPN) independence and the length of follow-up (minimum 1 year) after surgery. We reviewed our experience from 2003 to 2013 with minimum 1-year follow-up, dealing with reconnection surgery in 13 adults affected by < 100 cm SBS after massive small bowel resection: autologous gastrointestinal reconstruction was not feasible. Three (out of 5168 screened papers) non randomized controlled trials with 116 adult patients were analysed showing weaning from TPN (40%, 50% and 90% respectively) after reconnection surgery without autologous gastrointestinal reconstruction. Among our 13 adults, mean age was 54.1 years (53.8 % ASA III): 69.2 % had a high stomal output (> 500 cc/day) and TPN dependence was 100%. We performed a jejuno-colonic anastomosis (SBS type II) in 53.8%, in 46.1% of cases without ileo-cecal valve, leaving a mean residual small bowel length of 75.7 cm. In-hospital mortality was 0%. After a minimum period of 1 year of intestinal rehabilitation, all our patients (100%) went back to oral intake and 69.2% were off TPN (9 patients). No one was listed for transplantation. A residual small bowel length of minimum 75 cm, even if reconnected to part of the colon, seems able to produce a TPN independence without autologous gastrointestinal reconstruction after a minimum period of 1 year of intestinal rehabilitation. PMID- 29182899 TI - Five year experience of the treatment of squamous cell carcinoma of the anus. AB - OBJECTIVES: The best treatment of early stage anal squamous cell carcinoma (SCC) is under debated. Wide local excision (WLE) may be considered adequate for stage 1 anal margin cancer. This study demonstrates our experience in treatment of patients with SCC over 5 years. PATIENTS AND METHODS: We conducted a retrospective study of patients who had undergone anal screening or anal cancer surveillance between October 2010 and 2015 in our department. Each patient underwent anal Pap test, HPV test PCR HPV DNA and cytology by Thin Prep. The examinations were performed by Proctostation THD(c). Data were collected and analysed. RESULTS: We included 25 patients, 16 male (64%) and 9 female (36%). Twenty-four patients had SCC and 1 patient had adenocarcinoma. Of this cohort: 10 underwent chemoradiotherapy (CRT) because T3-4 N1-2 M0, 13 underwent only surgery because T1/T2 and 2 patients had CRT and surgery because they already have had anal cancer treated in the past with CRT. Seventeen patients (68%) of this cohort, including 5 with micro-invasive SCCs, had regular follow-up without recurrences. Four patients (17%) died from metastatic disease and 4 patients (17%) had recurrent disease. CONCLUSIONS: In this small cohort we demonstrated satisfactory results in treatment of SCCs, underlining the effective role of surgery in early stages of SCC. Screening program and follow up were fundamental to identify early stage and recurrent disease. Also we found the High-resolution video-proctoscopy a valid diagnostic tool. PMID- 29182900 TI - Laparoscopic sleeve gastrectomy for morbid obesity: role of intraluminal and intraperitoneal postoperative drainage. AB - BACKGROUND AND AIMS: Bleeding and staple line leak are the most common postoperative complications of LSG. To prevent and/or to promptly identify such complications, conventional peri-operative protocols imply post-operative gastric decompression (NGT) and staple line drain (IAD). Our aim was to evaluate the role of naso-gastric tube (NGT) and intra-abdominal drain (IAD) in preventing and/or facilitating identification and treatment of post-operative complications after sleeve gastrectomy. PATIENTS AND METHODS: A retrospective observational study on two consecutive series has been undertaken to evaluate the real utility of routine placement of NGT and IAD at the end of a LSG to prevent (primary end point), promptly identify (secondary end-point) and manage (tertiary end-point) bleeding and staple line leakage. Collected outcome data of all consecutive cases, which underwent primary LSG at our Department, were analyzed. The first 100 consecutive patients (group A) received the standard perioperative protocol and the other consecutive 100 (group B) received a fast track protocol (no NGT neither IAD). RESULTS: The two groups were not different in their outcome. Two bleeding occurred in Group A and were conservatively treated. One abscess developed in group B soon after surgery. It was diagnosed by an abdominal CT performed because patients presented fever, leucocitosis and tachycardia. It was successfully treated by percutaneous ultrasound-guided drainage. One fistula occurred in group B after discharge on 30th post-operative day. Fistula was suspected based on fever and tachycardia in absence of any abdominal discomfort and was confirmed by an abdominal CT. The patient was successfully treated in 40 days by endoscopic positioning of a gastric tube-prosthesis and percutaneous ultrasound-guided drainage of abdominal collection. A third patient in group B experienced bleeding suspected due to hemoglobin drop and confirmed by abdominal CT. He also was conservatively treated. CONCLUSIONS: In conclusion, placement of drains does not facilitate detection of leak, abscess, or bleeding after primary LSG.

PMID- 29182901 TI - Surgery for post-operative entero-cutaneous fistulas: is bowel resection plus primary anastomosis without stoma a safe option to avoid early recurrence? Report on 20 cases by a single center and systematic review of the literature. AB - BACKGROUND: A review was performed on entero-cutaneous fistula (ECF) repair and early recurrence, adding our twenty adult patients (65% had multiple fistulas). METHODS: The search yielded 4.098 articles but only 15 were relevant: 1.217 patients underwent surgery. The interval time between fistula's diagnosis and operative repair was between 3 months and 1 year. A bowel resection with primary anastomosis was performed in 1.048 patients, 192 (18.3%) underwent a covering stoma: 856 patients (81.7%) had a fistula takedown in one procedure. RESULTS: The patients had 14.3% recurrence and 13.1% mortality rate. In our experience 75% were surgically treated after a period equal or above one year from fistula occurrence: surgery was very demolitive (in 40% remnant small bowel was less than 100 cm). We performed a bowel resection with a hand-sewn anastomosis (95%) without temporary stoma. In-hospital mortality was 0% and at discharge all were back to oral intake with 0% early re-fistulisation. CONCLUSIONS: Literature supports our experience: ECF takedown could be safely performed after an adequate period of recovery from 3 months to one year from fistula occurrence. In our series primary repair (bowel resection plus reconnection surgery without temporary stoma) avoided an early recurrence without mortality. PMID- 29182903 TI - Total laparoscopic splenectomy for giant epidermoid cyst: a case report. AB - INTRODUCTION: Splenic cysts are benign tumors, accidentally detected using US or CT scan. They are classified into true cyst (primary, 25%) and pseudocyst (secondary, 75%). Conventional treatment of splenic cyst, especially giant, symptomatic and complicated has been open or laparoscopic total splenectomy. Recently, partial splenectomy is recommended as well to preserve its hematopoietic function and homeostasis of blood, but it is not considered safe for complications as intra and post operative bleeding. CASE REPORT: A 46 years old man, martial arts practitioner, underwent US abdomen scan because of left upper quadrant pain, with evidence of a splenic mass. He underwent also CT and MRI, which revealed "oval giant splenic mass of 12 cm diameter located in superior splenic pole that can be firstly referred to cyst". Considered patient's frequency to thoraco-abdominal traumas, we decided to perform a total laparoscopic splenectomy. Surgical treatment was performed with a three trocar technique and lasted 150 minutes. Post-operative follow-up was regular and abdominal drain was removed in 4th POD (Post Operative Day). Patient was discharged in 5th POD. Pathological examination revealed epidermoid cyst. CONCLUSIONS: Total splenectomy needs to be performed in cases of giant cyst and in our limited experience it is a safe approach.

A rare case of a ruptured SAA in a 38-year old female, firstly treated with endovascular embolization and then with splenectomy, is presented. A 38-year old female presented to the emergency department with epigastric pain and fainting episodes. Direct catheter angiography revealed a ruptured SAA and distal, as well as proximal coil embolization was performed. Due to abdominal compartment syndrome the patient underwent open surgery with splenic artery ligation and splenectomy. Postoperative she showed signs of sepsis and was treated with i.v. fluids, steroids, packed red blood cells, platelets, fresh frozen plasma and antimicrobial treatment. Additionally, a multidrug resistant Acinetobacter baumanni was yielded from the urine culture. She had a satisfactory recovery. She is followed up a total of 5 years with no signs of overwhelming post-splenectomy infection syndrome. Direct catheter angiography is a very helpful option in diagnosis, as well as treatment, but a close monitoring after embolization is essential. Furthermore, post-splenectomy sepsis is a severe disease with high mortality rates that requires immediate appropriate treatment. PMID- 29182905 TI - Is There a Difference in Intra-Articular Injections of Corticosteroids, Hyaluronate, or Placebo for Temporomandibular Osteoarthritis? AB - PURPOSE: Corticosteroids are widely used for treatment of temporomandibular joint (TMJ) osteoarthritis (OA). This study investigated the effects of corticosteroids on TMJOA compared with placebo or hyaluronate. MATERIALS AND METHODS: The authors designed and implemented a systematic review and meta-analysis to compare the effects of intra-articular injection of corticosteroid, hyaluronate, or placebo for patients with TMJOA. The authors searched related randomized controlled studies electronically in multiple English- and Chinese-language electronic databases. The predictor variable was intra-articular injection with corticosteroid, hyaluronate, or placebo. Primary outcome variables were pain intensity and maximal mouth opening. Other variables included success rate and adverse events. Meta-analyses were performed with Rev Man 5.3. RESULTS: Eight studies met the inclusion criteria. Meta-analysis showed that corticosteroid injections after arthrocentesis were superior to placebo in relieving pain as assessed with the visual analog scale (mean difference [MD], -0.74; 95% confidence interval [CI], -1.34 to -0.13; P = .02; I2 = 0%) in the long-term, but was inferior in increasing maximal mouth opening (MD, -2.06; 95% CI, -2.76 to 1.36; P < .00001; I2 = 28%). Although corticosteroid and hyaluronate injections without arthrocentesis decreased pain and improved maximal mouth opening, the corticosteroid group had a significantly lower success rate (odds ratio = 0.41; 95% CI, 0.17-1.00; P = .05; I2 = 0%) than the hyaluronate group in the short term. CONCLUSION: Corticosteroid injections after arthrocentesis are recommended for patients with TMJOA to relieve joint pain rather than increase maximal mouth opening. Corticosteroid and hyaluronate have marked effectiveness on TMJOA; however, hyaluronate might be the better alternative to some extent.

AB - A retrospective cohort study, were evaluated: polymyxin B plus aminoglycosides or polymyxin B plus other antibiotics. Any degree of acute kidney injury occurred in 26 (86.6%) patients. The median time to acute kidney injury was 6.0 (95% CI 3-14) days in the polymyxin-aminoglycoside containing regimen group, against 27.0 (95% CI 6-42) days in the polymyxin with other antimicrobial combinations group (p=0.03). Polymyxin B with aminoglycosides group progressed faster to any degree of renal dysfunction. PMID- 29182907 TI - Evaluation of the suitability of a plant virus, pepper mild mottle virus, as a surrogate of human enteric viruses for assessment of the efficacy of coagulation rapid sand filtration to remove those viruses. AB - Here, we evaluated the removal of three representative human enteric viruses - adenovirus (AdV) type 40, coxsackievirus (CV) B5, and hepatitis A virus (HAV) IB and one surrogate of human caliciviruses - murine norovirus (MNV) type 1 - by coagulation-rapid sand filtration, using water samples from eight water sources for drinking water treatment plants in Japan. The removal ratios of a plant virus (pepper mild mottle virus; PMMoV) and two bacteriophages (MS2 and phiX174) were compared with the removal ratios of human enteric viruses to assess the suitability of PMMoV, MS2, and phiX174 as surrogates for human enteric viruses. The removal ratios of AdV, CV, HAV, and MNV, evaluated via the real-time polymerase chain reaction (PCR) method, were 0.8-2.5-log10 when commercially available polyaluminum chloride (PACl, basicity 1.5) and virgin silica sand were used as the coagulant and filter medium, respectively. The type of coagulant affected the virus removal efficiency, but the age of silica sand used in the rapid sand filtration did not. Coagulation-rapid sand filtration with non sulfated, high-basicity PACls (basicity 2.1 or 2.5) removed viruses more efficiently than the other aluminum-based coagulants. The removal ratios of MS2 were sometimes higher than those of the three human enteric viruses and MNV, whereas the removal ratios of phiX174 tended to be smaller than those of the three human enteric viruses and MNV. In contrast, the removal ratios of PMMoV were similar to and strongly correlated with those of the three human enteric viruses and MNV. Thus, PMMoV appears to be a suitable surrogate for human enteric viruses for the assessment of the efficacy of coagulation-rapid sand filtration to remove viruses. PMID- 29182908 TI - Outdoor and indoor air quality and cognitive ability in young children. AB - BACKGROUND: This study examined outdoor and indoor air quality at ages 9 months and 3 years and their association with cognitive ability at age 3 in England and Wales. METHOD: Data from 8198 Millennium Cohort Study children were analysed using multilevel regression. Outdoor air quality was assessed with mean annual estimates of nitrogen dioxide (NO2) levels within a standard small area (ward). Indoor air quality was measured with parent-reports of damp or condensation in the home and exposure to secondhand smoke in the home. Cognitive ability was assessed with the British Ability Scales Naming Vocabulary subscale and the Bracken School Readiness Assessment. RESULTS: In adjusted models, consistent exposure to high levels of NO2 at age 9 months and age 3 years was associated with lower verbal ability at age 3 years. Damp/condensation and secondhand smoke in the home at either age or at both ages were correlated with lower school readiness at age 3 years. Exposures to damp/condensation at age 3 years or at both ages and secondhand smoke at either age or at both ages were associated with lower verbal ability at age 3 years. CONCLUSION: Young children's exposures to indoor damp or condensation and secondhand smoke are likely to be detrimental for their cognitive outcomes. However, there do not appear to be any short-term effects of NO2. PMID- 29182909 TI - Association between media coverage and prevalence of idiopathic environmental intolerance attributed to electromagnetic field in Taiwan. AB - Idiopathic environmental intolerance attributed to electromagnetic fields (IEI EMF) describes symptoms sufferers attribute to exposure to electromagnetic fields (EMF). In Taiwan, the prevalence rate of IEI-EMF was 13.3% in 2007, but a survey using the same method found the rate declined to 4.6% in 2012. Because media reports may encourage readers to attribute their symptoms to EMF, the change might be related to media coverage. We searched articles indexed in the largest newspaper database in Taiwan to evaluate the association between media coverage and the prevalence of IEI-EMF. We also assessed the effects of other potential affecting factors. The number of newspaper articles related to EMF and IEI-EMF increased from 2005 to 2007 and then has been decreasing until 2012, which is compatible with the change in the prevalence of IEI-EMF. However, from 2007 to 2012, the other potential affecting factors such as density of mobile phone base stations, number of mobile phone users, total mobile phone calling time, and number of text messages sent through mobile phones all increased in Taiwan. This finding indicated a positive association between media coverage and the prevalence of IEI-EMF in Taiwan, which might also be true in other countries. PMID- 29182910 TI - Peptide-based biosensors: From self-assembled interfaces to molecular probes in electrochemical assays. AB - Redox-tagged peptides have emerged as functional materials with multiple applications in the area of sensing and biosensing applications due to their high stability, excellent redox properties and versatility of biomolecular interactions. They allow direct observation of molecular interactions in a wide range of affinity and enzymatic assays and act as electron mediators. Short helical peptides possess the ability to self-assemble in specific configurations with the possibility to develop in highly-ordered, stable 1D, 2D and 3D architectures in a hierarchical controlled manner. We provide here a brief overview of the electrochemical techniques available to study the electron transfer in peptide films with particular interest in developing biosensors with immobilized peptide motifs, for biological and clinical applications. PMID- 29182911 TI - Electrode-based AC electrokinetics of proteins: A mini-review. AB - Employing electric phenomena for the spatial manipulation of bioparticles from whole cells down to dissolved molecules has become a useful tool in biotechnology and analytics. AC electrokinetic effects like dielectrophoresis and AC electroosmosis are increasingly used to concentrate, separate and immobilize DNA and proteins. With the advance of photolithographical micro- and nanofabrication methods, novel or improved bioanalytical applications benefit from concentrating analytes, signal enhancement and locally controlled immobilization by AC electrokinetic effects. In this review of AC electrokinetics of proteins, the respective studies are classified according to their different electrode geometries: individual electrode pairs, interdigitated electrodes, quadrupole electrodes, and 3D configurations of electrode arrays. Known advantages and disadvantages of each layout are discussed. PMID- 29182912 TI - SMC complexes sweeping through the chromosome: going with the flow and against the tide. AB - Bacteria transcribe, duplicate and segregate their genomes all at once. Conflicts between DNA replication and active transcription are a major source of DNA damage and jeopardize genome integrity and cell survival. Co-orientation of replication forks and transcription units is thought to reduce the impact of such conflicts. Like transcription and replication, chromosome segregation relies on the translocation of multi-subunit protein complexes along DNA. Here, I highlight recent advances in our understanding of two major classes of structural maintenance of chromosomes (SMC) complexes in bacteria: Smc-ScpAB, whose DNA translocation is co-oriented with DNA replication by specific start sites, and MukBEF, which apparently lacks such co-ordination. Potential advantages of centralized and decentralized approaches to chromosome organization are discussed.

AB - The General Medical Council (United Kingdom) advocates development of non-core curriculum Student Selected Components and their inclusion in all undergraduate medical school curricula. This article describes a rationale for the design, delivery, assessment and evaluation of Student Selected Components in Forensic and Legal Medicine. Reference is made to the available evidence based literature pertinent to the delivery of undergraduate medical education in the subject area. A Student Selected Component represents an opportunity to highlight the importance of the legal aspects of medical practice, to raise the profile of the discipline of Forensic and Legal Medicine amongst undergraduate medical students and to introduce students to the possibility of a future career in the area. The authors refer to their experiences of design, delivery, assessment and evaluation of Student Selected Components in Forensic and Legal Medicine at their respective Universities in the Republic of Ireland (Galway) and in the United Kingdom (Oxford). PMID- 29182914 TI - Detection of proximal conduction blocks using a triple stimulation technique improves the early diagnosis of Guillain-Barre syndrome. AB - OBJECTIVE: Current diagnostic electrophysiological criteria can miss the early stages of Guillain-Barre syndrome (GBS). We evaluated the diagnostic efficiency of the triple stimulation technique (TST) in highlighting proximal conduction blocks (CBs) in patients who do not meet the electrophysiological criteria for GBS. METHODS: All patients with a diagnosis of clinical GBS referred to our center between September 2014 and January 2016 were included in the study. For patients who did not fulfill the electrophysiological criteria of GBS, we performed the TST examination. RESULTS: Among the 44 included patients, 86% fulfilled the electrophysiological criteria of GBS during the initial nerve conduction study (NCS). The six remaining patients had proximal CBs revealed by TST examination. Therefore, a combination of a conventional NCS and the TST allowed 100% of the patients to be electrophysiologically diagnosed. CONCLUSIONS: TST is useful for the diagnosis of GBS in association with NCS, particularly in the early stages of the disease. SIGNIFICANCE: TST is a useful tool for GBS diagnosis at the early stages of the disease. PMID- 29182915 TI - Event-related neuronal responses to acoustic novelty in single-sided deaf cochlear implant users: Initial findings. AB - OBJECTIVE: A cochlear implant (CI) is an auditory prosthesis restoring profound hearing loss. However, CI-transmitted sounds are degraded compared to normal acoustic hearing. We investigated cortical responses related to CI-degraded against acoustic listening. METHODS: Event-related potentials (ERPs) were recorded from eight single-sided deaf CI users who performed a three-stimulus oddball task, separately with their normal hearing ear and CI ear. The oddball tones were occasionally intermitted by novel sounds. ERP responses were compared between electric and acoustic listening for the auditory (N1) and auditory cognitive (Novelty P3, Target-P3) ERP components. RESULTS: CI-degraded listening was associated with attenuated sensory processing (N1) and with attenuated early cortical responses to acoustic novelty whereas the late cortical responses to acoustic novelty and the target-P3 did not differ between NH and CI ears. CONCLUSION: The present study replicates the CI-attenuation of Novelty-P3 amplitudes in a within-subject comparison. Further, we show that the CI attenuation of Novelty-P3 amplitudes extends to early cortical responses to acoustic novelty, but not to late novelty responses. SIGNIFICANCE: The dissociation into CI-attenuated P3 early Novelty-P3 amplitudes and CI-unaffected late Novelty-P3 amplitudes represents a cortical fingerprint of CI-degraded listening. It further contributes to general claims of distinct auditory Novelty P3 sub-components. PMID- 29182916 TI - What is the optimal frequency range for quantifying slow EEG activity in neonates?

PMID- 29182917 TI - Natural radioactivity in soils of the state of Rio de Janeiro (Brazil): Radiological characterization and relationships to geological formation, soil types and soil properties. AB - Located in the south-western part of Brazil, the state of Rio de Janeiro is geotectonically contained within a complex structural province that resulted in the amalgamation of the Western Gondwana Paleocontinent. To undertake an extensive radiological characterization of this complex geological province and investigate the influence of bedrock, soil type and soil chemical-physical characteristics on natural radionuclide levels in soils, 259 surface soil samples were collected that encompassed the main soil types and geological formations throughout the state. Gamma spectrometry analysis of the samples resulted in median values of 114 Bq.kg-1for 40K, 32 Bq.kg-1 for 226Ra and 74 Bq.kg-1 for 228Ra. The median value for 226Ra was similar to the world median value for soils, the 40K value was well below the worldwide value, and that for 228Ra exceeded the world median value. The intense weathering caused by the high rainfall rates and high temperatures may be responsible for the low levels of 40K in the soils, of which the strongly acidic and clayey soils are markedly K depleted. A soil from a high-grade metamorphic rock (granulite) presented the lowest 226Ra (18 Bq.kg-1) content, whereas the highest levels for 226Ra (92 Bq.kg 1) and 228Ra (139 Bq.kg-1) were observed in a young soil enriched in primary minerals (Leptsol). A lowland soil (Gleysol) showed the highest median of 40K (301 Bq.kg-1). Strongly acidic soils tended to present high amounts of 226Ra, and sandy soils tended to contain low levels of 228Ra. The external radiation dose indicates that the state has a background radiation level within the natural range. PMID- 29182918 TI - Clustering analysis strategies for electron energy loss spectroscopy (EELS). AB - In this work, the use of cluster analysis algorithms, widely applied in the field of big data, is proposed to explore and analyze electron energy loss spectroscopy (EELS) data sets. Three different data clustering approaches have been tested both with simulated and experimental data from Fe3O4/Mn3O4 core/shell nanoparticles. The first method consists on applying data clustering directly to the acquired spectra. A second approach is to analyze spectral variance with principal component analysis (PCA) within a given data cluster. Lastly, data clustering on PCA score maps is discussed. The advantages and requirements of each approach are studied. Results demonstrate how clustering is able to recover compositional and oxidation state information from EELS data with minimal user input, giving great prospects for its usage in EEL spectroscopy. PMID- 29182919 TI - An atomic force microscopy mode for nondestructive electromechanical studies and its application to diphenylalanine peptide nanotubes. AB - Nondestructive scanning probe microscopy of fragile nanoscale objects is currently in increasing need. In this paper, we report a novel atomic force microscopy mode, HybriD Piezoresponse Force Microscopy (HD-PFM), for simultaneous nondestructive analysis of piezoresponse as well as of mechanical and dielectric properties of nanoscale objects. We demonstrate this mode in application to self assembled diphenylalanine peptide micro- and nanotubes formed on a gold-covered substrate. Nondestructive in- and out-of-plane piezoresponse measurements of tubes of less than 100 nm in diameter are demonstrated for the first time. High resolution maps of tube elastic properties were obtained simultaneously with HD PFM. Analysis of the measurement data combined with the finite-elements simulations allowed quantification of tube Young's modulus. The obtained value of 29 +/- 1 GPa agrees well with the data obtained with other methods and reported in the literature. PMID- 29182920 TI - Effect of asymmetric morphology on coupling surface plasmon modes and generalized plasmon ruler. AB - Plasmon coupling in aggregated noble metal systems can provide a path to manipulate the optical response purposefully and possesses a wide range of application. Previously, most studies focused on the coupling behavior of Ag-Ag dimers with the same shape. However, plasmon coupling between nanoparticles at different morphologies can provide a new way to modulate optical properties due to broken of symmetry. In this work, we investigate systematically the coupling modes of asymmetric Ag-Ag heterodimers consisting of different morphologies by the boundary element method (BEM). Herein nanoparticles with different surface curvatures (modified by rounding parameter e) are constructed and combined as asymmetric Ag-Ag heterodimers. Simulated electron energy loss spectroscopy (EELS) spectra and eigenmodes are combined to analyze the evolution of coupling modes. The mode energy degeneracy and degeneracy breaking phenomena are found, while the charge states are always not degenerate, for the first time by modulating symmetry of the morphology. It is also found that coupling gap mode G2 can only be excited for Ag-Ag heterodimers with quite small separation distance, and will be greatly influenced by nanogap morphology. The rounded effect can also cause distinct blue shift of bounding dipolar modes. These results provide the possibility to modulate optical response by using different asymmetric dimers effectively. In contrast, optical response of high-order coupling modes is less sensitive to topographic effect than that of low-order coupling modes. Moreover, plasmon ruler for asymmetric Ag-Ag heterodimers is investigated and we demonstrate that a generalized plasmon ruler is applicable to predict the relative shift of coupling dipolar due to change of separation distance. PMID- 29182921 TI - Hydroxypyridinone-benzofuran hybrids with potential protective roles for Alzheimer's disease therapy. AB - A series of (3-hydroxy-4-pyridinone)-benzofuran hybrids have been developed and studied as potential multitargeting drugs for Alzheimer's disease (AD). Their design envisaged mainly to mimic the donepezil drug, a marketed inhibitor of acetylcholinesterase (AChE), and to endow the conjugate molecules with extra properties such as metal chelation, radical scavenging and inhibition of amyloid peptide (Abeta) aggregation. Thus, a set of eleven new hybrid compounds was developed and evaluated for chemical and biological properties, in solution and in neuronal cell environment. The results are discussed in terms of the type of substituents on both main moieties and the linker size. The closest similarity with donepezil, in terms of AChE inhibitory activity, was obtained for the O benzyl-hydroxypyridinone hybrids containing a 2-methylene linker, although still less active than the drug. However, the free-hydroxypyridinone hybrids present higher activity for the Abeta aggregation inhibition, metal chelating capacity and radical scavenging activity. Overall, some compounds demonstrated capacity to exert a multiple action by hitting three- (7d) or four- (8d, 8f) pathophysiological targets of AD. Furthermore, the compounds showed neuroprotective effects in neuronal cells subjected to model stressors of AD, but not significant dependence on the substituent groups. Importantly, the compounds evidenced drug-likeness properties, including good membrane permeability. PMID- 29182923 TI - Association between dietary patterns and depressive symptoms among middle-aged adults in China in 2016-2017. AB - The purpose of this study was to explore the associations of dietary patterns with depressive symptoms in middle-aged Chinese adults. The cross-sectional study participants were 1360 Chinese adults (45-59 years, 659 males and 701 females) who participated in a Health Survey at the time of periodic checkup. Dietary intakes were assessed via a semi-quantitative food frequency questionnaire (FFQ). Binary logistic regression analysis was used to estimate odds ratio(OR) and 95% confidence interval(CI) for depressive symptoms according to quartiles of each dietary pattern score. Four major dietary patterns were identified by factor analysis: traditional Chinese, Western, grains-vegetables and high-salt patterns. After controlling for potential confounders, participants in the highest quartile of the Western pattern scores had greater odds of depressive symptoms than those in the lowest quartile. In contrast, participants in the highest quartile of the grains-vegetables pattern had lower odds of depressive symptoms than those in the lowest quartile. Nevertheless, no significant associations were observed between the traditional Chinese and high-salt patterns and the risk of depressive symptoms, even after adjusting for potential confounders. The findings indicate that the Western pattern is associated with an increased risk, and the grains vegetables pattern is associated with a reduced risk of depressive symptoms. PMID- 29182922 TI - Quantitative trait loci for sensitivity to acute ethanol and ethanol consummatory behaviors in rats. AB - Individuals with a low initial response to alcohol (i.e., ethanol) are at greater risk of developing alcohol abuse or dependence later in life. Similar to humans, individual differences in ethanol sensitivity also can be seen in rats, and several laboratories have used these individual differences to generate selectively bred rats that differ in acute ethanol sensitivity. We have worked with two sets of such rats (Inbred High or Low Alcohol Sensitivity strains, IHAS or ILAS, respectively; Inbred Alcohol Tolerant or Non-Tolerant strains, IAT and IANT, respectively) and have confirmed previously mapped quantitative trait loci (QTL) for these acute differences with the use of recombinant congenic lines; however, the relationship between acute sensitivity and ethanol drinking in these rats has yet to be determined. Thus, here we tested the hypothesis that QTLs underlying variation in initial low sensitivity to ethanol also will modulate variation in ethanol drinking behaviors. Separate groups of selectively inbred parent and congenic rats were tested for the loss of righting response (LORR) and also assessed for ethanol consummatory behavior using either operant self administration or an intermittent-access two-bottle choice procedure. LORR testing confirmed the presence of a LORR duration QTL in all of the congenics; however, the lack of a corresponding difference in blood ethanol concentration at the regaining of the righting response suggests that these QTLs may be mediating a difference in ethanol metabolism rather than in neuronal sensitivity. IHAS/ILAS derived congenic rats did not differ from parent rats at any point during operant self-administration. IAT/IANT-derived congenic rats showed small, but significant, increases in ethanol consumption relative to the parent strains only during the initial stages of operant self-administration. In contrast to operant testing, IHAS/ILAS-derived congenic rats showed significantly greater ethanol consumption and preference than parent rats during intermittent-access testing. There were not differences, however, between IAT/IANT congenic and parent rats during intermittent access. These data support the hypothesis that there is a genetic relationship between initial ethanol sensitivity and ethanol consumption, at least for the IHAS/ILAS-derived congenic rats. Our current studies, however, cannot eliminate pharmacokinetic or taste preference factors as contributing to the rats' responses, nor can we eliminate the possibility of a linkage effect because of the fairly large size of the QTL intervals; i.e., distinct genes may be mediating the acute sensitivity and drinking responses. PMID- 29182924 TI - Control of anthracnose caused by Colletotrichum species in guava, mango and papaya using synergistic combinations of chitosan and Cymbopogon citratus (D.C. ex Nees) Stapf. essential oil. AB - This study assessed the efficacy of chitosan (Chi) and Cymbopogon citratus (D.C. ex Nees) Stapf. essential oil (CCEO) combinations to control the mycelial growth of five pathogenic Colletotrichum species (C. asianum, C. siamense, C. fructicola, C. tropicale and C. karstii) in vitro, as well as the anthracnose development in guava (Psidium guajava L.) cv. Paluma, mango (Mangifera indica L.) cv. Tommy Atkins and papaya (Carica papaya L.) cv. Papaya artificially inoculated with these species. Combinations of Chi (2.5, 5 or 7.5mg/mL) and CCEO (0.15, 0.3, 0.6 or 1.25MUL/mL) inhibited the mycelial growth of all tested fungal species in vitro. Examined Chi-CCEO combinations showed additive or synergistic interactions to inhibit the target Colletotrichum species based on the Abbott index. Coatings formed by synergistic Chi (5mg/mL) and CCEO (0.15, 0.3 or 0.6MUL/mL) combinations decreased anthracnose lesion development in guava, mango and papaya inoculated with any of the tested Colleotrichum species during storage. Overall, anthracnose lesion development inhibition in fruit coated with synergistic Chi-CCEO combinations was higher than that observed in fruit treated with synthetic fungicides. These results show that the application of coatings formed by Chi CCEO synergistic combinations could be effective to control postharvest anthracnose development in fruit. PMID- 29182925 TI - To reveal the nature of interactions of human hemoglobin with gold nanoparticles having two different morphologies (sphere and star-shaped) by using various spectroscopic techniques. AB - The nature of interactions between heme protein human hemoglobin (HHb) and gold nanoparticles of two different morphologies that is GNP (spherical) and GNS (star shaped) have been investigated by using UV-vis absorption, steady state fluorescence, synchronous fluorescence, resonance light scattering (RLS), time resolved fluorescence, FT-IR, and circular dichroism (CD) techniques under physiological condition of pH ~7 at ambient and different temperatures. Analysis of the steady state fluorescence quenching of HHb in aqueous solution in the presence of GNP and GNS suggests that the nature of the quenching is of static type. The static nature of the quenching is also confirmed from time resolved data. The static type of quenching also indicates the possibility of formation of ground state complex for both HHb-GNP and HHb-GNS systems. From the measurements of Stern-Volmer (SV) constants KSV and binding constants, KA and number of binding sites it appears that HHb forms stronger binding with GNP relative to GNS. Analysis of the thermodynamic parameters indicates that the formation of HHb GNP and HHb-GNS complexes are spontaneous molecular interaction processes (?G<0). In both cases hydrogen bonding and van der Waals interactions play a dominant role (?H<0, ?S<0). Synchronous fluorescence spectroscopy further reveals that the ground state complex formations of HHb-GNP and HHb-GNS preferably occur by binding with the amino acid tyrosine through hydrogen bonding interactions. Moreover the alpha-helicity contents of the proteins as obtained from the circular dichroism (CD) spectra appears to be marginally reduced by increasing concentrations of GNP and GNS and the alpha-helical structures of HHb retain its identity as native secondary structure in spite of complex formations with GNP or GNS. These findings demonstrate the efficiency of biomedical applications of GNP and GNS nanoparticles as well as in elucidating their mechanisms of action as drugs or drug delivery systems in human.

AB - In this study, poly(dopamine-quinone chromium (III))-microspheres (PDQCM) were used for the modification of graphite paste electrode (GPE) for simultaneous voltammetric determination of 4-Amino Phenol (AP), Phenol (Ph) and 4-Nitro Phenol (NP). The PDQCM and the GPE modified with PDQCM were characterized by field emission scanning electron microscopy, Energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, electrochemical impedance spectroscopy and electrochemistry methods such as cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The proposed modified electrode exhibits high electrocatalytic activity toward electrooxidation of AP, Ph, and NP to three well separated peaks in the potential range from 0.2 to 1.3V using CV and DPV methods in phosphate buffer solution with pH 2.0. Under the optimum conditions, detection limits of 0.5, 0.6 and 0.8uM were obtained for AP, Ph, and NP, respectively. Moreover, GPE/PDQCM was successfully used for simultaneous determination of AP, Ph, and NP in tap and river waters. PMID- 29182927 TI - Insights into a hole transfer mechanism between glucose oxidase and a p-type organic semiconductor. AB - This manuscript describes a bioelectrochemical application of a new class of electrochemically generated hole-transporting (p-type) polymeric semiconductors (HTPS), which are based on a carbazole core and the oxiran and thiiran reactive groups. Electrode based on transparent layer of indium tin oxide was electrochemically modified with a layer of HTPS and a monolayer of covalently immobilized glucose oxidase (GOx). The HTPS/GOx-based electrode was investigated for an evaluation of direct hole-transfer between the enzyme and electrode at a bio-electrochemically relevant potential via HTPS layer. The broad linear relationship between the peak-current density and glucose concentration from 2 to 15mM and high stability of ITO/poly-CzS/GOx-electrode was observed. Moreover, it was determined that charge transfer rate constants are reliable for the establishment of advanced electron transfer between enzyme and electrode for the application of this HTPS/GOx-based electrode in long-lived biofuel cells and amperometric biosensors.

This approach was informed by the development of a pseudo first-order rate constant model, and tested in a paper based assay format using a fusion construct consisting of an rcSso7d binding module and a cellulose-binding domain. These rcSso7d-CBD fusion proteins were solubly expressed and purified from bacteria in high molar yields, and enable oriented, high-density adsorption of the rcSso7d binding species to unmodified cellulose within a 30-second incubation period. These findings were validated using two distinct, antigen-specific rcSso7d variants, which were isolated from a yeast surface display library via flow cytometry. Up to 1.6 micromoles of rcSso7d CBD was found to adsorb per gram of cellulose, yielding a volume-averaged binder concentration of up to 760MUM within the resulting active material. At this molar abundance, the target antigen is captured from solution with nearly 100% efficiency, maximizing the attainable sensitivity for any given diagnostic system. PMID- 29182929 TI - Nitration of tyrosine and its effect on DNA hybridization. AB - One major marker of nitrosative stress is the formation of 3-Nitrotyrosine (3-NT) from Tyrosine (Tyr) by adding a nitro group (-NO2) with nitrating agents. Nitration of Tyr often causes loss of protein activity and is linked with many diseases. In this article, we detect 3-NT and discriminate it from Tyr with Differential Pulse Voltammetry (DPV) as it is a very important biomarker. We first examined redox (oxidation/reduction) properties and stability of 3-NT in detail. Second, we provided the Tyr and 3-NT discrimination with DPV and compared with the chromatography. We then explored the interaction of 3-NT and DNA oligonucleotides. Our findings demonstrate that 3-NT can be used as a new electrochemical indicator, which is able to detect hybridization of probe (single stranded DNA-ssDNA) and hybrid (double stranded DNA-dsDNA) both via 3-NT reduction and guanine oxidation signal changes at the same time. The signal differences enabled us to distinguish ssDNA and dsDNA without using a label or a tag. Moreover, we achieved to detect hybridization of DNA by using the reduction signal of 3-NT obtained at -0.4V vs. Ag/AgCl. More importantly, we observed the changes of the reduction signals of 3-NT after the interaction of probe and hybrid sequences. We showed that 3-NT signal decreases more with hybrid than the probe. Our platform, for the first time, demonstrates the detection of hybridization both guanine oxidation and indicator reduction signal changes at the same time. Moreover, we, for the first time, demonstrated the interaction between 3-NT and DNA. PMID- 29182930 TI - Electrochemical immunosensors - A powerful tool for analytical applications. AB - Immunosensors are biosensors based on interactions between an antibody and antigen on a transducer surface. Either antibody or antigen can be the species immobilized on the transducer to detect antigen or antibody, respectively. Because of the strong binding forces between these biomolecules, immunosensors present high selectivity and very high sensitivity, making them very attractive for many applications in different science fields. Electrochemical immunosensors explore measurements of an electrical signal produced on an electrochemical transductor. This signal can be voltammetric, potentiometric, conductometric or impedimetric. Immunosensors utilizing electrochemical detection have been explored in several analyses since they are specific, simple, portable, and generally disposable and can carry out in situ or automated detection. This review addresses the potential of immunosensors destined for application in food and environmental analysis, and cancer biomarker diagnosis. Emphasis is given to the approaches that have been used for construction of electrochemical immunosensors. Additionally, the fundamentals of immunosensors, technology of transducers and nanomaterials and a general overview of the possible applications of electrochemical immunosensors to the food, environmental and diseases analysis fields are described.

AB - Managers of invasive species consider the peer-reviewed literature only moderately helpful for guiding their management programs. Though this "knowing doing gap" has been well-described, there have been few efforts to guide scientists in how to develop useful and usable science. Here we demonstrate how a comprehensive survey of managers (representing 42 wetland management units across the Great Salt Lake watershed) can highlight management practices and challenges (here for the widespread invasive plant, Phragmites australis, a recent and aggressive invader in this region) to ultimately inform a research program. The diversity of surveyed organizations had wide-ranging amounts of Phragmites which led to different goals and approaches including more aggressive control targets and a wider array of control tools for smaller, private organizations compared to larger government-run properties. We found that nearly all managers (97%) used herbicide as their primary Phragmites control tool, while burning (65%), livestock grazing (49%), and mowing (43%) were also frequently used. Managers expressed uncertainties regarding the timing of herbicide application and type of herbicide for effective control. Trade-offs between different Phragmites treatments were driven by budgetary concerns, as well as environmental conditions like water levels and social constraints like permitting issues. Managers had specific ideas about the plant communities they desired following Phragmites control, yet revegetation of native species was rarely attempted. The results of this survey informed the development of large-scale, multi-year Phragmites control and native plant revegetation experiments to address management uncertainties regarding herbicide type and timing. The survey also facilitated initial scientist-manager communication, which led to collaborations and knowledge co-production between managers and researchers. An important outcome of the survey was that experimental results were more pertinent to manager needs and trusted by managers. Such an approach that integrates manager surveys to inform management experiments could be adapted to any developing research program seeking to be relevant to management audiences. PMID- 29182932 TI - Structure-based design for binding peptides in anti-cancer therapy. AB - The conventional anticancer therapeutics usually lack cancer specificity, leading to damage of normal tissues that patients find hard to tolerate. Ideally, anticancer therapeutics carrying payloads of drugs equipped with cancer targeting peptides can act like "guided missiles" with the capacity of targeted delivery toward many types of cancers. Peptides are amenable for conjugation to nano drugs for functionalization, thereby improving drug delivery and cellular uptake in cancer-targeting therapies. Peptide drugs are often more difficult to design through molecular docking and in silico analysis than small molecules, because peptide structures are more flexible, possess intricate molecular conformations, and undergo complex interactions. In this review, the development and application of strategies for structure-based design of cancer-targeting peptides against GRP78 are discussed. This Review also covers topics related to peptide pharmacokinetics and targeting delivery, including molecular docking studies, features that provide advantages for in vivo use, and properties that influence the cancer-targeting ability. Some advanced technologies and special peptides that can overcome the pharmacokinetic challenges have also been included.

AB - This paper presents evidence on intra-household retirement externalities by assessing the causal effect of spousal retirement on various health behaviors and health status across 19 European countries. We identify partner's and own retirement effects by applying a fuzzy regression discontinuity design using retirement eligibility as exogenous instruments for spousal and own retirement status. We find significant increases in the frequency and intensity of alcohol consumption combined with a significant decrease in moderate physical activities as a response to partner's retirement. In line with the existing literature, we find that own retirement has significant positive effects on engaging in moderate and vigorous physical activities but also leads to a significant increase in the frequency of alcohol intake. Overall, subjective health is negatively affected by spousal retirement and positively by own retirement. PMID- 29182933 TI - MSC exosomes mediate cartilage repair by enhancing proliferation, attenuating apoptosis and modulating immune reactivity. AB - Mesenchymal stem cell (MSC) exosome was previously shown to be effective in repairing critical size osteochondral defects in an immunocompetent rat model. Here we investigate the cellular processes modulated by MSC exosomes and the mechanism of action underlying the exosome-mediated responses in cartilage repair. We observed that exosome-mediated repair of osteochondral defects was characterised by increased cellular proliferation and infiltration, enhanced matrix synthesis and a regenerative immune phenotype. Using chondrocyte cultures, we could attribute the rapid cellular proliferation and infiltration during exosome-mediated cartilage repair to exosomal CD73-mediated adenosine activation of AKT and ERK signalling. Inhibitors of AKT or ERK phosphorylation suppressed exosome-mediated increase in cell proliferation and migration but not matrix synthesis. The role of exosomal CD73 was confirmed by the attenuation of AKT and ERK signalling by AMPCP, a CD73 inhibitor and theophylline, an adenosine receptor antagonist. Exosome-treated defects also displayed a regenerative immune phenotype characterised by a higher infiltration of CD163+ regenerative M2 macrophages over CD86+ M1 macrophages, with a concomitant reduction in pro inflammatory synovial cytokines IL-1beta and TNF-alpha. Together, these observations demonstrated that the efficient osteochondral regeneration by MSC exosomes was effected through a coordinated mobilisation of multiple cell types and activation of several cellular processes. PMID- 29182935 TI - Health care expenditures, age, proximity to death and morbidity: Implications for an ageing population. AB - This paper uses Hospital Episode Statistics, English administrative data, to investigate the growth in admitted patient health care expenditures and the implications of an ageing population. We use two samples of around 40,000 individuals who (a) used inpatient health care in the financial year 2005/06 and died by the end of 2011/12 and (b) died in 2011/12 and had some hospital utilisation since 2005/06. We use a panel structure to follow individuals over seven years of this administrative data, containing estimates of inpatient health care expenditures (HCE), information regarding individuals' age, time-to-death (TTD), morbidities at the time of an admission, as well as the hospital provider, year and season of admission. We show that HCE is principally determined by proximity to death rather than age, and that proximity to death is itself a proxy for morbidity. PMID- 29182936 TI - Does health insurance coverage fall when nonprofit insurers become for-profits? AB - In exchange for tax exemptions, Blue Cross and Blue Shield (BCBS) health insurers were expected to provide health insurance to the "bad risks," those for whom coverage was unavailable from other insurers. I present evidence that five years after a BCBS plan converted to for-profit status, the probability of having insurance was 1.4 percentage points higher, a 9% reduction in the uninsured. The increase in coverage does not mask reductions among populations often targeted by public policies. However, there is evidence of increased risk selection which suggests that the bad risks might have been worse off after a conversion.

PMID- 29182938 TI - Does disease cause vaccination? Disease outbreaks and vaccination response. AB - Parental fear of vaccines has limited vaccination rates in the United States. I test whether disease outbreaks increase vaccination using a new dataset of county level disease and vaccination data. I find that pertussis (whooping cough) outbreaks in a county decrease the share of unvaccinated children entering kindergarten. These responses do not reflect changes in the future disease risk. I argue that these facts are best fit by a model in which individuals are both myopic and irrational. This suggests that better promotion of information about outbreaks could enhance the response. PMID- 29182939 TI - The lyssavirus host-specificity conundrum-rabies virus-the exception not the rule. AB - Lyssaviruses are a diverse range of viruses which all cause the disease rabies. Of the 16 recognized species, only rabies viruses (RABV) have multiple host reservoirs. Although lyssaviruses are capable of infecting all mammals, onward transmission in a new host population requires adaptation of the virus, in a number of stages with both host and virus factors determining the outcome. Due to an absence of recorded non-RABV host shifts, RABV data is extrapolated to draw conclusions for all lyssaviruses. In this article, we have focused on evidence of host shifts in the same insectivorous bat reservoir species in North America (RABV) and Europe (EBLV-1, EBLV-2 and BBLV). How RABV has successfully crossed species barriers and established infectious cycles in new hosts to be the global multi-host pathogen it is today, whilst other lyssaviruses appear restricted in host species is explored in this review. It hypothesized that RABV is the exception, rather than the rule, in this fascinating genus of viruses. PMID- 29182940 TI - Clinical study of optical coherence tomography in the diagnosis of peripheral pulmonary artery thrombus. AB - BACKGROUND: Peripheral pulmonary artery thrombus (PPT) is common in the clinic. However, due to the lack of an ideal diagnostic tool, PPT cannot be quickly diagnosed and effectively treated at present. Optical coherence tomography (OCT) is a new intravascular imaging technique that is characterized by high image resolution. This technique is suitable for small vessel imaging and has the ability to distinguish red and white thrombi. OBJECTIVE: This study aimed to evaluate the value of OCT in the diagnosis of PPT and in identifying the nature of thrombi by comparing the difference in sensitivity between OCT and selective pulmonary angiography (SPA). METHODS: Highly suspected PPT patients were enrolled in this study. Pulmonary ventilation/perfusion (V/Q) mismatch pulmonary segments or peripheral pulmonary arteries were chosen. SPA was performed first, followed by OCT imaging. The diagnostic standard of thrombus with SPA was an intraluminal filling defect. The procedure and criteria for OCT diagnosis of thrombus were previously introduced in intracoronary OCT thrombus images. The diameter of the imaging vessels was measured, and they were grouped according to diameter. The diameter was <2mm in the distal segment group, 2-3mm in the middle segment group, and >3mm in the proximal segment group. The recognition abilities of intravascular thrombus with the different diameters of these two techniques were compared. Patients with obvious clinical symptoms and more red thromboses revealed by OCT were given standardized anticoagulant therapy for half a year. The clinical symptoms, 6-minute walking test and changes in the thrombus in the OCT images of these patients before and after treatment were observed. RESULTS: A total of 22 patients with highly suspected PPT were suggested to undergo V/Q inspection. Finally, 12 patients were eligible for the study. SPA and OCT were performed in 61 peripheral pulmonary arteries in all 12 patients. The ideal SPA and OCT images obtained from a total of 76 blood vessel segments were suitable for comparative analysis. A total of 62 thrombi were found by SPA. Among these, eight thrombi were in the distal segment, 29 thrombi were in the middle segment, and 25 thrombi were in the proximal segment. A total of 81 thrombi were found by OCT, among which 22 thrombi were in the distal segment, 31 were in the middle segment, and 28 were in the proximal segment. There was a significant difference between two groups in the distal segment group (P=0.013), while there was no significant difference between two groups in the middle segment group or the proximal segment group (P>0.05). In addition to all the thrombi found by SPA, OCT found other thrombi that were missed by SPA. According to previous OCT images for determining the nature of thrombi, OCT revealed 81 thrombi, of which 48 (59%) were red thrombi and 33 (41%) were white thrombi. Then, seven patients who had obvious clinical symptoms and more red thrombi in the peripheral pulmonary artery were given anticoagulant therapy for six months. After treatment, these symptoms were improved, oxygenation indexes increased, and the six-minute walking test was extended in all these patients. After anticoagulation therapy, five patients underwent OCT review. These OCT images were matched and compared before and after anticoagulation therapy. The results revealed that most of the thrombi had disappeared, and a small amount of red thrombi turned white as the volume reduced. The mean lumen area before and after treatment was 2.05+/-1.03mm2 and 2.86+/-1.24mm2, respectively, and the difference was statistically significant (P=0.035). CONCLUSION: OCT can clearly show the structure of the lumen and the wall of the peripheral pulmonary artery tube. The sensitivity of the diagnosis of PPT with a diameter of <2mm was higher than that of SPA. Moreover, OCT has the ability to distinguish between red and white thrombi, which is of guiding significance in anticoagulant therapy. PMID- 29182941 TI - Magnetoencephalography reveals an increased non-target P3a, but not target P3b, that is associated with high non-clinical psychosocial deficits. AB - Auditory processing deficits are frequently identified in autism and schizophrenia, and the two disorders have been shown to share psychosocial difficulties. This study used magnetoencephalography to investigate auditory processing differences for those with a high degree of a non-clinical autistic and schizotypal trait phenotype, Social Disorganisation (SD). Participants were 18 low (9 female) and 19 high (9 female) SD scorers (18-40 years) who completed a three-stimulus auditory oddball paradigm of speech sounds (standard: 100ms 'o', deviant: 150ms 'o', novel: 150ms 'e'). Spatio-temporal cluster analysis revealed increased amplitude for the high SD group in a left (p = 0.006) and a right (p = 0.020) hemisphere cluster in response to the novel non-target. No cluster differences were found in response to the target deviant. These findings suggest that those with a high degree of the SD phenotype recruit more cortical resources when processing unattended, novel speech stimuli, which may lead to psychosocial deficits. PMID- 29182942 TI - Does MnTBAP ameliorate DNA fragmentation and in vivo fertility of frozen-thawed Arabian stallion sperm? AB - Overproduction of reactive oxygen species during sperm freeze-thawing process leads to membrane lipid peroxidation, DNA damage, motility loss, and subsequent death. This oxidative stress can be alleviated by the addition of some antioxidants to semen extenders prior to freezing. This study was performed to evaluate the in vitro effectiveness of MnTBAP (a cell permeable antioxidant) on stallion sperm freezability and in vivo fertility rate. Twenty-one ejaculates were, collected with missouri model artificial vagina (n = 3 stallions, seven ejaculate each), and diluted (1:2 v/v) with phosphocaseinate base INRA extender, containing 0 (control), 100, 200 and 300 MUM of MnTBAP and frozen using acontrolled-rate freezing system. The following parameters were determined: sperm motility, viability, membrane integrity, acrosome abnormalities, lipid peroxidation and DNA fragmentation. MnTBAP improved horse semen quality parameters in a dose-dependent manner. The100 MUM concentration of MnTBAP did not show a significant difference in semen parameters compare with control group (p > 0.05). Accordingly, the extender supplemented with 200 MUM resulted in higher sperm total and progressive motility (55.3 +/- 4.28% and 33.2 +/- 2.90%), viability (43.9 +/- 2.14%), and membrane integrity (50.8 +/- 2.14%), provided a greater protective effect in the percentage of total abnormalities compare to other groups (p < 0.05), and showed lower sperm with damaged DNA with lower MDA levels (p < 0.001). Higher concentrations (300 MUM) not only did not improve the results but inversely affected sperm parameters. Twelve mares were used for fertility trial in the cross over study of 60 deep horn inseminations performed using control (9/30 pregnancy/mare) and 200 MUM - MnTBAP (14/30 pregnancy/mere) groups frozen semen. The Average pregnancy rates were not significantly different between control and treated group (30% and 46.66%respectively) (p > 0.05). Under the conditions of this study, 200 MUM - MnTBAP reduced the oxidative stress and protect the DNA fragmentation of Arabian stallion sperm during cryopreservation; but did not improved pregnancy rates. PMID- 29182943 TI - Effect of sorting boar spermatozoa by sex chromosomes on oviduct cell binding. AB - This study examined the hypothesis that flow sorting sperm by sex chromosomes affects oviduct cell binding which would influence formation of the sperm reservoir in the oviduct. The sperm-rich fraction from boars (n = 5) was collected, sperm were stained with Hoechst 33342 and sorted. Sperm were sorted based on the presence of either an X or Y chromosome and placed into the following treatments: 1) sperm selected for the Y chromosome, 2) selected for the X, 3) an equal mixture of sorted X and Y, and 4) a control of non-sorted sperm from the same collection. Samples were tested for oviduct cell binding within 12 h of sorting. Additionally, sperm were analyzed for motility characteristics, acrosome status, and binding to the two oviduct glycan motifs that bind porcine sperm, biantennary 6-sialylated N-acetyllactosamine on a mannose core (bi-SiaLN) and sulfated LeX trisaccharide (suLeX). The disaccharide found within both glycan motifs, N-acetyllactosamine (LacNAc), was used as a control. Sperm binding to oviduct cells was reduced by more than half in the three sorted samples when compared to the control sperm that were not sorted. The percentage of sperm that were motile 24 h after sorting was also decreased significantly in each of the sorted sample groups when compared to the unsorted control. In contrast, sorting did not decrease the percentage of sperm that bound purified soluble glycans or the location on sperm to which they bound. There was also no difference in sperm acrosome status among the four groups. In summary, sorting reduced sperm binding to the complex matrix around oviductal cell aggregates but sperm binding to purified soluble oviduct glycans was not affected. The requirement for higher affinity and motility to bind glycans immobilized on oviduct cells may explain this difference. The reduction in sperm fertility observed following sex-sorting may be explained partially by a reduced or altered ability to bind to the oviduct epithelium. PMID- 29182944 TI - Learning to feel tired: A learning trajectory towards chronic fatigue. AB - Chronic fatigue complaints are frequently reported in the general population and fatigue ranks among the most commonly reported symptoms in chronic disease. In contrast to its high prevalence and impact on quality of life, relatively little is understood about the etiology of chronic fatigue. We present a cognitive behavioral framework, the 'ALT+F' model, that conceptualizes fatigue from an associative learning perspective, and we will evaluate the current evidence for this position. Central to this framework is the notion that interoceptive and exteroceptive stimuli can become associated with the fatigue experience. Consequently, these stimuli may acquire the capacity to elicit fatigue as well as anticipatory fear-related avoidance behavior. We will argue that associative learning processes may contribute to the development of chronic fatigue, fear of fatigue, avoidance of fatigue and activity, and eventually, functional disability. The extent to which associative learning processes give rise to chronic fatigue and fear-related avoidance behavior may depend on a number of risk factors, including perceptual-cognitive biases, sensitization, fatigue catastrophizing, and excessive generalization. The presented framework offers a new window on treatment and intervention options for chronic fatigue. PMID- 29182946 TI - Effect of pulse duration and pulse repetition frequency of cavitation histotripsy on erosion at the surface of soft material. AB - Cavitation histotripsy with the short pulse duration (PD) but high pulse repetition frequency (PRF) disintegrates the tissue at a fluid interface. However, longer PD and lower PRF are used in the other focused ultrasound applications, where the acoustic radiation force, streaming, and cavitation are different, and their effects on erosion are unknown. In this study, the erosion at the surface of phantom/ex vivo tissue and the characteristics of induced bubble cloud captured by high-speed photography, passive cavitation detection, and light transmission during histotripsy exposure at varied PDs and PRFs but the same duty cycle were compared. The peak negative pressure of 6.6 MPa at the PD of 20 ms and PRF of 1 Hz began to erode the phantom, which becomes more significant with the increase of peak negative pressure, PD, and interval time between bursts. The increase of the PRF from 1 Hz to 1000 Hz, while the decrease of the PD from 20 ms to 20 MUs (duty cycle of 2%) at the same energy was delivered to the gel phantom immersed in the degassed water led to the decrease of erosion volume but a slight increase of the erosion area and smoother surface. Low PRF and long PD produce the significant tissue deformation, acoustic wave refocusing, confinement of bubbles in a conical region, and more bubble dissolution after the collapse for the high acoustic scattering and light transmission signals. In comparison, high PRF and low PD produce a wide distribution of bubbles with only little wave refocusing at the beginning of cavitation histotripsy and high inertial cavitation. Acoustic emission dose has a good correlation with the erosion volume. The erosion on the porcine kidney at the varied PRFs and PDs with the same energy output showed similar trends as those in the phantom but at a slow rate. In summary, the PRF and PD are important parameters for the cavitation histotripsy-induced erosion at the interface of fluid and soft material, and they should be optimized for the best outcome. PMID- 29182945 TI - Low-intensity pulsed ultrasound (LIPUS) stimulates mineralization of MC3T3-E1 cells through calcium and phosphate uptake. AB - The present study aimed to evaluate the effect of low-intensity pulsed ultrasound (LIPUS) on pre-osteoblast mineralization using in vitro bioassays. Pre osteoblastic MC3T3-E1 cells were exposed to LIPUS at 1 MHz frequency, 0.2 W/cm2 intensity and 20% duty cycle for 30 min. The analyses were carried out up to 336 h (14 days) after exposure. The concentration of collagen, phosphate, alkaline phosphatase, calcium and transforming growth factor beta 1 (TGF-beta1) in cell supernatant and the presence of calcium deposits in the cells were analyzed. Our results showed that LIPUS promotes mineralized nodules formation. Collagen, phosphate, and calcium levels were decreased in cell supernatant at 192 h after LIPUS exposure. However, alkaline phosphatase and TGF-beta1 concentrations remained unchanged. Therapeutic pulsed ultrasound is capable of stimulating differentiation and mineralization of pre-osteoblastic MC3T3-E1 cells by calcium and phosphate uptake with consequent hydroxyapatite formation. PMID- 29182947 TI - Low-level neural auditory discrimination dysfunctions in specific language impairment-A review on mismatch negativity findings. AB - In specific language impairment (SLI), there is a delay in the child's oral language skills when compared with nonverbal cognitive abilities. The problems typically relate to phonological and morphological processing and word learning. This article reviews studies which have used mismatch negativity (MMN) in investigating low-level neural auditory dysfunctions in this disorder. With MMN, it is possible to tap the accuracy of neural sound discrimination and sensory memory functions. These studies have found smaller response amplitudes and longer latencies for speech and non-speech sound changes in children with SLI than in typically developing children, suggesting impaired and slow auditory discrimination in SLI. Furthermore, they suggest shortened sensory memory duration and vulnerability of the sensory memory to masking effects. Importantly, some studies reported associations between MMN parameters and language test measures. In addition, it was found that language intervention can influence the abnormal MMN in children with SLI, enhancing its amplitude. These results suggest that the MMN can shed light on the neural basis of various auditory and memory impairments in SLI, which are likely to influence speech perception. PMID- 29182948 TI - Mozart's music in children with drug-refractory epileptic encephalopathies: Comparison of two protocols. AB - In this prospective, randomized, open label study, we compared the effect on seizure recurrence and quality-of-life parameters, of two different protocols of music therapy in children and adolescents with refractory epileptic encephalopathies. Nine out of 19 patients (13 males and 6 females, aged between 1 and 24years) were randomized to listen to Mozart's sonata in D major for two pianos K448 for 2h/day for 2weeks; other 10 children were randomized on a set of Mozart's compositions. In group 1 (K448), 2/9 children (22.2%) had a >=75% seizure decrease; two patients had less than 50% seizure reduction, and the other five were unchanged. In group 2 (set Mozart), 7/10 patients (70%) had a significant seizure reduction (specifically, >=50% in 1/10; >=75% in 4/10; 100% in 2/10). An overall more significant behavioral improvement including less irritability and tearfulness, reduced self-/heteroaggression, a better daytime vigilance, and nighttime sleep quality, was also reported in children from group 2. In conclusion, the present study seems to confirm that music therapy may be an additional, nonpharmacological, effective treatment for patients with refractory epileptic seizures in childhood. The Mozart's set of different compositions can be better accepted and effective than the K448.

AB - Inflammation is a fundamental physiological process that is essential for survival of human being but at the same time is one of the major causes of human morbidity and mortality. In the past decade, numerous advances have taken place in the understanding and development of novel anti-inflammatory drugs. Therefore, investigation of newest anti-inflammatory agents is still a major challenge. In this study, novel and successfully synthesized naproxen-derivatives indicated powerful anti-inflammatory properties as potent of COX-1 and/or COX-2 inhibitors are reported. Results obtained revealed the presence of very potent derivatives with% inhibition of the oedema by 100% in addition to enzyme inhibition values that can reach 92%. The molecular docking and molecular dynamic calculations have been studied. Thus, new potent candidates for further investigation as prospective non-steroidal anti-inflammatory drug were proposed. Furthermore, twenty of the synthesized derivatives have been selected by the NCI, USA for anti cancer screening and some of the tested compounds showed good% growth inhibition and some selectivity against some cell lines such as melanoma, non-small cell lung and colon cancer with GI% values ranging from 60.9 to 82.8%. Structure activity relationship has been performed and molecular modeling studies and molecular dynamic simulations have been performed for more explanation of the action of the synthesized compounds. PMID- 29182951 TI - The aetiology of borderline personality disorder (BPD): contemporary theories and putative mechanisms. AB - This article presents an overview of current knowledge regarding the aetiology of Borderline Personality Disorder (BPD). It begins with a brief synopsis of early research and theory, and discusses how changing conceptualisations of BPD have impacted on our aetiological knowledge. Contemporary theories are described and presented within a developmental psychopathology framework. Deficient co regulation and social communication in infancy are purported to underpin emotional dysregulation and social cognition deficits across development. These mechanisms are further potentiated by maladaptive social experiences in a series of positive feedback loops. Prospective research provides preliminary evidence for the reciprocal (or mediating) effects of maladaptive experiences and childhood dysregulation. Moving forward, cohort studies may incorporate neurobiological assessments to examine the biological systems underpinning phenotypic (e.g., impulsivity, disturbed relatedness) covariation. PMID- 29182949 TI - Modeling the potential health benefits of lower household air pollution after a hypothetical liquified petroleum gas (LPG) cookstove intervention. AB - INTRODUCTION: Improved biomass and advanced fuel cookstoves can lower household air pollution (HAP), but levels of fine particulate matter (PM2.5) often remain above the World Health Organization (WHO) recommended interim target of 35MUg/m3. METHODS: Based on existing literature, we first estimate a range of likely levels of personal PM2.5 before and after a liquefied petroleum gas (LPG) intervention. Using simulations reflecting uncertainty in both the exposure estimates and exposure-response coefficients, we estimate corresponding expected health benefits for systolic blood pressure (SBP) in adults, birthweight, and pneumonia incidence among children <2years old. We also estimate potential avoided premature mortality among those exposed. RESULTS: Our best estimate is that an LPG stove intervention would decrease personal PM2.5 exposure from approximately 270MUg/m3 to approximately 70MUg/m3, due to likely continued use of traditional open-fire stoves. We estimate that this decrease would lead to a 5.5mmHg lower SBP among women over age 50, a 338g higher birthweight, and a 37% lower incidence of severe childhood pneumonia. We estimate that decreased SBP, if sustained, would result in a 5%-10% decrease in mortality for women over age 50. We estimate that higher birthweight would reduce infant mortality by 4 to 11 deaths per 1000 births; for comparison, the current global infant mortality rate is 32/1000 live births. Reduced exposure is estimated to prevent approximately 29 cases of severe pneumonia per year per 1000 children under 2, avoiding approximately 2-3 deaths/1000 per year. However, there are large uncertainties around all these estimates due to uncertainty in both exposure estimates and in exposure-response coefficients; all health effect estimates include the null value of no benefit. CONCLUSIONS: An LPG stove intervention, while not likely to lower exposure to the WHO interim target level, is still likely to offer important health benefits.

This article systematically reviews the literature on the evaluation of oral soft tissue blood microcirculation by LDF. We analysed the available literature through October 2016 using the database resources Medline/PubMed, the Cochrane Oral Health Group Specialist Trials Register and the ISI Web of Knowledge. Several points emerged from this literature review The use of LDF involves specific constraints; however, the influence of different factors (temperature, tobacco, pressure etc.) must be adequately controlled when using LDF. LDF measurements of soft tissue within the oral cavity vary depending on the anatomical site. In dentistry, LDF can be used to track healing progress in periodontal surgery and to diagnose vascular flow changes in the connective tissue of mucosae covered by a removable prosthesis at an early stage prior to the onset of clinical inflammation signs.

AB - This paper extends on previous research on the extraction and statistical analysis on relevant dynamic features (width, grayscale and radian combined with writing sequence information) in forensic handwriting examinations. In this paper, a larger signature database was gathered, including genuine signatures, freehand imitation signatures, random forgeries and tracing imitation signatures, which are often encountered in casework. After applying Principle Component Analysis (PCA) of the variables describing the proximity between specimens, a two dimensional kernel density estimation was used to describe the variability of within-genuine comparisons and genuine-forgery comparisons. We show that the overlap between the within-genuine comparisons and the genuine-forgery comparisons depends on the imitated writer and on the forger as well. Then, in order to simulate casework conditions, cases were simulated by random sampling based on the collected signature dataset. Three-dimensional normal density estimation was used to estimate the numerator and denominator probability distribution used to compute a likelihood ratio (LR). The comparisons between the performance of the systems in SigComp2011 (based on static features) and the method presented in this paper (based on relevant dynamic features) showed that relevant dynamic features are better than static features in terms of accuracy, false acceptance rate, false rejection rate and calibration of likelihood ratios.

AB - The ability of neurons to modify or remodel their synaptic connectivity is critical for the function of neural circuitry throughout the life of an animal. Understanding the mechanisms underlying neuronal structural changes is central to our knowledge of how the nervous system is shaped for complex behaviors and how it further adapts to developmental and environmental demands. Caenorhabditis elegans provides a powerful model for examining developmental processes and for discovering mechanisms controlling neural plasticity. Recent findings have identified conserved themes underlying neural plasticity in development and under environmental stress.

AB - Specially trained dogs have long been used by law enforcement agencies to help in criminal investigations and in searching for missing persons. Still, it is unclear which components of human scent released into the environment contribute to successful searches of individuals. In this study, saliva and axillary sweat samples were taken from a total of 190 people. Additionally, DNA was extracted from whole blood of seven different people and used as an odour sample as well. Overall 675 tests (trails) were performed during a period of 18 months. The ability to track individuals with the odour samples mentioned above was examined with seven dogs, four of which were specially-trained dogs (mantrailer) from the Saxony Police. Results indicated that specially-trained police dogs can track a person with an average success rate of 82% and correctly identify the absence of an odour track with an average success rate of 97% under various conditions. Private rescue dogs were less successful with an average success rate of 65% and 75% respectively. These data suggest that the potential error rate of a well trained handler team is low and can be a useful tool for law enforcement personnel. Saliva, as a reference odour source, was found to be particularly suitable for the search. The results of the study suggest that the components contained in axillary sweat, saliva and DNA extracted from whole blood are sufficient, serving as a key stimulus for individualized searches. PMID- 29182956 TI - Unintentional mortality associated with paracetamol and codeine preparations, with and without doxylamine, in Australia. AB - INTRODUCTION: Misuse of paracetamol, codeine and doxylamine combination analgesics may lead to addiction and mortality. This study aimed to (1) identify unintentional deaths in Australia associated with use of combination analgesic products containing paracetamol, codeine and doxylamine; (2) describe cases characteristics, including demographics and additional medication use; and (3) identify common factors associated with misuse and mortality of these medicines in Australia. DESIGN: This retrospective case series analysed National Coronial Information System data to identify cases of unintentional death attributable to paracetamol, codeine and doxylamine products between 2002 and 2012. SETTING: Three Eastern Australian states: New South Wales, Queensland, Victoria, comprising a population of approximately 18.6 million people. RESULTS: 441 unintentional deaths attributed to paracetamol/codeine products were identified; doxylamine was detected in 102 cases (23%). Overall unintentional death rates rose from 0.9-per-million in 2002 to 3.6-per-million in 2009, declining to 1.9 per-million in 2012. Median age at time of death was 48, half of all cases occurred between 35-54 years of age, and 57% were female. Concomitant medication use was detected in 79% of cases, including benzodiazepines, other opioids, psychiatric medications, alcohol and illicit drugs. Behaviours consistent with drug misuse including doctor/pharmacy shopping, excessive dosages and extended use, were identified in 24% of cases. CONCLUSIONS: This study identified 441 deaths associated with codeine-combination analgesic products across three Australian states; with an average of 40 deaths per year. Death commonly involved multiple substance use and abuse behaviours indicative of misuse and dependence.

AB - INTRODUCTION: The genetic Lauge-Hansen classification is used for reconstruction of the mechanism of ankle injury. In this study, we addressed the question of agreement between the mechanism of the fracture as postulated by the Lauge-Hansen classification and mechanism reported by the patient in rotational ankle fractures. MATERIAL AND METHODS: Radiographs of 78 patients with acute malleolar fractures were analyzed and compared with fracture mechanisms reported by these patients. RESULTS: The patient reported mechanisms were in concordance with the mechanism deducted from the X-rays in 49% of cases. Only 17% of patients who recalled a pronation trauma actually had radiographs classified as pronation fractures while 76% of patients who recalled a supination trauma were also radiographically classified as having sustained supination type fractures. CONCLUSION: The Lauge-Hansen classification should be used with caution for determining the actual mechanism of injury as it was able to predict the patient reported fracture mechanism in less than 50% of cases. A substantial percentage of fractures appearing radiographically as supination type injuries may have been actually produced by a pronation fracture mechanism.

Ten steers were supplemented with vitamin A weekly, while the other ten steers did not receive any additional vitamin A. The results demonstrated that the restriction of vitamin A intake increased intramuscular fat (IMF) by 46%. This was a function of the total number of marbling flecks increasing by 22% and the average marbling fleck size increasing by 14%. Vitamin A restriction resulted in marbling flecks that were less branched (22%) and slightly more round (4%) with an increased minor axis length (7%). However, restricting vitamin A did not affect the size of the intramuscular or subcutaneous adipocyte cells or the subcutaneous fat depth. The results suggest that vitamin A affects the amount of marbling and other attributes of the marbling flecks due to hyperplasia rather than hypertrophy. This may explain why vitamin A restriction specifically affects IMF rather than subcutaneous fat deposition. PMID- 29182959 TI - Social biases modulate the loss of redundant forms in the cultural evolution of language. AB - According to the competitive exclusion principle (Gause, 1934), competition for the same niche must eventually lead one competitor to extinction or the occupation of a new niche. This principle applies in both biology and the cultural evolution of language, where different words and structures compete for the same function or meaning (Aronoff, 2016). Across languages, for example, word order trades off with case marking as a means of indicating who did what to whom in a sentence. Previous experimental work has shed light on how such trade-offs come about as languages adapt to human biases through learning and production, with biases becoming amplified through iterated learning over generations. At the same time, a large body of work has documented the impact of social biases on language change. However, little work has investigated how social biases interact with learning and production biases. In particular, the social dimension of language may provide alternative niches for otherwise redundant forms, preventing or slowing their extinction. We tested this hypothesis in an iterated-learning experiment in which participants were exposed to a language with two dialects, both of which had fixed word order, but differed in whether they employed case markers. In one condition, we biased participants socially towards speakers of the dialect that employed case; in other conditions we provided no bias, or biased participants for or against the dialect without case. As expected under our hypothesis, the use of case markers declined over time in all conditions, but the social bias in favor of case-dialect speakers slowed the decline.

AB - Bone marrow is the primary hematopoietic organ, which is involved in multiple malignant diseases including acute and chronic leukemia, multiple myeloma, myelodysplastic syndromes, and bone metastases from solid tumors. These malignancies affect normal homeostasis and reshape the bone marrow microenvironment. There are limited treatment options for them because of their inevitable aggravation. The current systemic administration of anticancer agents is difficult to achieve ideal therapeutic dose to suppress tumor growth at bone marrow diseased sites, and is always associated with a high incidence of relapse and severe side effects. The limitations of current treatments urge scientists to develop bone marrow targeted drug delivery systems intended for the treatment of diseased bone marrow, which can improve the efficacy of therapeutic agents and reduce their dose-limiting systemic side effects on healthy tissues. In this review we first present the current opinions on bone marrow vasculature, as well as the molecular and structural interactions between tumor cells and the diseased bone marrow. In the second part, we highlight the different design rationales and strategies of bone marrow delivery systems and their therapeutic applications for the treatment of malignancies inside the bone marrow. PMID- 29182961 TI - Matrix stiffness determines the phenotype of vascular smooth muscle cell in vitro and in vivo: Role of DNA methyltransferase 1. AB - Cells perceive the physical cues such as perturbations of extracellular matrix (ECM) stiffness, and translate these stimuli into biochemical signals controlling various aspects of cell behavior, which contribute to the physiological and pathological processes of multiple organs. In this study, we tested the hypothesis that during arterial stiffening, vascular smooth muscle cells (SMCs) sense the increase of ECM stiffness, which modulates the cellular phenotype through the regulation in DNA methyltransferases 1 (DNMT1) expression. Moreover, we hypothesized that the mechanisms involve intrinsic stiffening and deficiency in contractility of vascular SMCs. Substrate stiffening was mimicked in vitro with polyacrylamide gels. A contractile-to-synthetic phenotypic transition was induced by substrate stiffening in vascular SMCs through the down-regulation of DNMT1 expression. DNMT1 repression was also observed in the tunica media of mice aortas in an acute aortic injury model and a chronic kidney failure model, as well as in the tunica intima of human carotid arteries with calcified atherosclerotic lesions. DNMT1 inhibition facilitates arterial stiffening in vivo and promotes osteogenic transdifferentiation, calcification and cellular stiffening of vascular SMCs in vitro. These effects may be attributable, at least in part, to the role of DNMT1 in regulating the promoter activities of Transgelin (SM22alpha) and alpha-smooth muscle actin (SMA) and the functional contractility of SMCs. We conclude that DNMT1 is a critical regulator that negatively regulates arterial stiffening via maintaining the contractile phenotype of vascular SMCs. This research may facilitate elucidation of the complex crosstalk between vascular SMCs and their surrounding matrix in healthy and in pathological conditions and provide new insights into the implications for potential targeting of the phenotypic regulatory mechanisms in material-related therapeutic applications. PMID- 29182962 TI - The possible worlds of global health research: An ethics-focused discourse analysis. AB - Representations of the world enable global health research (GHR), discursively constructing sites in which studies can legitimately take place. Depoliticized portrayals of the global South frequently obscure messy legacies of colonialism and motivate technical responses to health problems with political and economic root causes. Such problematic representations of the world have not yet been rigorously examined in relation to global health ethics, a major site of scholarly effort towards GHR that promotes justice and fairness. We carried out a discourse analysis of four guidance documents relevant to the ethical practice of GHR, purposively selecting texts covering different genres (UN documents and journal articles) and prominent GHR foci (HIV and clinical trials). In light of increasing acknowledgement of the lessons Indigenous health scholarship holds for global health ethics, the four analyzed texts also included a set of principles developed to support Indigenous nation-building. Three of four documents featured global disparities as reasons for ethical caution. These inequalities appeared without explanation or causes, with generation of new scientific knowledge following as a logical response to such disparities. The fourth - Indigenous health-focused - document clearly identified 'colonialism' as a reason for both inequities in society, and related harmful research practices. Solutions to disparities in this text did not necessarily involve cutting-edge research, but focused instead on empowerment and responsiveness to community priorities and needs. These contrasting representations of the world were accomplished in ways that depended on texts' 'participants', or the people they represented; specific vocabularies or language usages; intertextual relationships to prior texts; and overall objectives or intentions of the author(s). Our results illustrate how ethics and other guidance documents serve as an important terrain for constructing, naturalizing or contesting problematic representations of the world of GHR. PMID- 29182963 TI - Female garment workers' experiences of violence in their homes and workplaces in Bangladesh: A qualitative study. AB - The ways in which women's engagement in paid work shapes their experiences of violence in the home and workplace is widely debated, particularly in Bangladesh, but rarely considered together. We undertook 23 in-depth interviews with female garment workers living in slums in Bangladesh, and nine interviews with key informants (factory managers and supervisors, male workers, and employees from non-governmental organisations). Data came from two studies conducted in Dhaka, Bangladesh - the first between August and September 2011 and the second between June and August 2015 - and were analysed using thematic analysis. In both settings, women experienced similar forms of violence, including emotional, physical, sexual, and economic, although from different perpetrators. Despite violence in the home and violence in the workplace typically being considered separately, we identify four overlaps between them. First, violence in both settings is shaped by how patriarchal norms and structures of institutions intersect with institutions economic structures. Second, dominant representations of female garment workers as sex workers or sexually promiscuous enables violence against them. Third, economic violence is used as a way to control and limit women's autonomy. Fourth, women develop strategies to continue working and maximize the benefits of work for themselves. Finally, we suggest how interventions could work to prevent violence in the home and workplace.

AB - In diffusion governed by Fick's law, the diffusion coefficient represents the phenomenological material parameter and is, in general, a constant. In certain cases of diffusion through porous media, the diffusion coefficient can be variable (i.e. non-constant) due to the complex process of solute displacements within microstructure, since these displacements depend on porosity, internal microstructural geometry, size of the transported particles, chemical nature, and physical interactions between the diffusing substance and the microstructural surroundings. In order to provide a simple and general approach of determining the diffusion coefficient for diffusion through porous media, we have introduced mass release curves as the constitutive curves of diffusion. The mass release curve for a selected direction represents cumulative mass (per surface area) passed in that direction through a small reference volume, in terms of time. We have developed a methodology, based on numerical Finite Element (FE) and Molecular Dynamics (MD) methods, to determine simple mass release curves of solutes through complex media from which we calculate the diffusion coefficient. The diffusion models take into account interactions between solute particles and microstructural surfaces, as well as hydrophobicity (partitioning). We illustrate the effectiveness of our approach on several examples of complex composite media, including an imaging-based analysis of diffusion through pancreatic cancer tissue. The presented work offers an insight into the role of mass release curves in describing diffusion through porous media in general, and further in case of complex composite media such as biological tissue. PMID- 29182965 TI - Real-time continuous recognition of knee motion using multi-channel mechanomyography signals detected on clothes. AB - Mechanomyography (MMG) signal has been recently investigated for pattern recognition of human motion. In theory, it is no need of direct skin contact to be detected and unaffected by changes in skin impedance. So, it is hopeful for developing wearable sensing device with clothes. However, there have been no studies so far to detect MMG signal on clothes and verify the feasibility of pattern recognition. For this study, 4-channel MMG signals were detected on clothes from the thigh muscles of 8 able-bodied participants. The support vector machines (SVM) classifier with 4 common features was used to recognize 6 knee motions and the average accuracy of nearly 88% was achieved. The accuracy can be further improved up to 91% by introducing a new proposed feature of the difference of mean absolute value (DMAV), but not by root mean square (RMS) or mean absolute value (MAV). Furthermore, the first-order Markov chain model was combined with the SVM classifier and it can avoid the misclassifications in some cases. For application to wearable power-assisted devices, this study would promote the developments of more flexible, more comfortable, and minimally obtrusive wearable sensing devices with clothes and recognition techniques of human motion intention. PMID- 29182966 TI - Sustained effects of volcanic ash on biofilm stoichiometry, enzyme activity and community composition in North- Patagonia streams. AB - Volcanic eruptions are extreme perturbations that affect ecosystems. These events can also produce persistent effects in the environment for several years after the eruption, with increased concentrations of suspended particles and the introduction of elements in the water column. On 4th June 2011, the Puyehue Cordon Caulle Volcanic Complex (40.59 degrees S-72.11 degrees W, 2200m.a.s.l.) erupted explosively in southern Chile. The area affected by the volcano was devastated; a thick layer of volcanic ash (up to 30cm) was deposited in areas 50 km east of the volcano towards Argentina. The aim of the present study was to evaluate the effect of volcanic ash deposits on stream ecosystems four years after the eruption, comparing biofilm stoichiometry, alkaline phosphatase activity, and primary producer's assemblage in streams which were severely affected by the volcano with unaffected streams. We confirmed in the laboratory that ash deposited in the catchment of affected streams still leach phosphorus (P) into the water four years after eruption. Results indicate that affected streams still receive volcanic particles and that these particles release P, thus stream water exhibits high P concentration. Biofilm P content was higher and the C:P ratio lower in affected streams compared to unaffected streams. As a consequence of less P in unaffected streams, the alkaline phosphatase activity was higher compared to affected streams. Cyanobacteria increased their abundances (99.9% of total algal biovolume) in the affected streams suggesting that the increase in P may positively affect this group. On the contrary, unaffected streams contained a diatom dominant biofilm. In this way, local heterogeneity was created between sub-catchments located within 30 km of each other. These types of events should be seen as opportunities to gather valuable ecological information about how severe disturbances, like volcanic eruptions, shape landscapes and lotic systems for several years after the event. PMID- 29182967 TI - The relationships between leaf economics and hydraulic traits of woody plants depend on water availability. AB - Leaf economics and hydraulic traits are simultaneously involved in the process of trading water for CO2, but the relationships between these two suites of traits remain ambiguous. Recently, Li et al. (2015) reported that leaf economics and hydraulic traits were decoupled in five tropical-subtropical forests in China. We tested the hypothesis that the relationships between economics and hydraulic traits may depend on water availability. We analysed five leaf economics traits, four hydraulic traits and anatomical structures of 47 woody species on the Loess Plateau with poor water availability and compared those data with Li et al. (2015) obtained in tropical-subtropical regions with adequate water. The results showed that plants on the Loess Plateau tend to have higher leaf tissue density (TD), leaf nitrogen concentrations and venation density (VD) and lower stomatal guard cell length (SL) and maximum stomatal conductance to water vapour (gwmax). VD showed positive correlations with leaf nitrogen concentrations, palisade tissue thickness (PT) and ratio of palisade tissue thickness to spongy tissue thickness (PT/ST). Principal component analysis (PCA) showed a result opposite from those of tropical-subtropical regions: leaf economics and hydraulic traits were coupled on the Loess Plateau. A stable correlation between these two suites of traits may be more cost-effective on the Loess Plateau, where water availability is poor. The correlation of leaf economics and hydraulic traits may be a type of adaptation mechanism in arid conditions. PMID- 29182968 TI - Testing the toxicity of metals, phenol, effluents, and receiving waters by root elongation in Lactuca sativa L. AB - Phytotoxicity tests using higher plants are among the most simple, sensitive, and cost-effective of the methods available for ecotoxicity testing. In the present study, a hydroponic-based phytotoxicity test using seeds of Lactuca sativa was used to evaluate the water quality of receiving waters and effluents near two industrial sites (Soyo and Daejon) in Korea with respect to the toxicity of 10 metals (As, Cd, Cr, Cu, Fe, Pb, Mn, Hg, Ni, Zn) and phenol, and of the receiving waters and effluents themselves. First, the L. sativa hydroponic bioassay was used to determine whether the receiving water or effluents were toxic; then, the responsible toxicant was identified. The results obtained with the L. sativa bioassay ranked the EC50 toxicities of the investigated metal ions and phenol as: Cd > Ni > Cu > Zn > Hg > phenol > As > Mn > Cr > Pb > Fe. We found that Zn was the toxicant principally responsible for toxicity in Daejeon effluents. The Daejeon field effluent had a higher Zn concentration than permitted by the effluent discharge criteria of the Ministry of Environment of Korea. Our conclusion on the importance of Zn toxicity was supported by the results of the L. sativa hydroponic assay, which showed that the concentration of Zn required to inhibit root elongation in L. sativa by 50% (EC50) was higher in the Daejeon field effluent than that of pure Zn. More importantly, we proved that the L. sativa hydroponic test method can be applied not only as an alternative tool for determining whether a given waste is acceptable for discharge into public water bodies, but also as an alternative method for measuring the safety of aquatic environments using EC20 values, with respect to the water pollutants investigated (i.e., Cd, Cr, Cu, Pb, Mn, Hg, Ni, Zn, and phenol). PMID- 29182969 TI - Simulated developmental and reproductive impacts on amphibian populations and implications for assessing long-term effects. AB - Fish endpoints measured in early life stage toxicity tests are often used as representative of larval amphibian sensitivity in Ecological Risk Assessment (ERA). This application potentially overlooks the impact of developmental delays on amphibian metamorphosis, and thereby reduced survival, in amphibian populations constrained by habitat availability. Likewise, the effects of reduced productivity or altered sexual development as a result of chemical exposure are not presented in terms of lower population fecundity in these surrogate tests. Translating endpoints measured in toxicity tests to those that are more representative of amphibian ecology and population dynamics provides a means of identifying how developmental effects result in long-term impacts. Here we compare effects of developmental delay on metamorphosis success in six anuran species and simulate population-level impacts of subsequent reductions in larval survival as well as potential reductions in fecundity as a result of developmental impacts. We use deterministic matrix models to compare realistic combinations of amphibian demographic rates and relative impacts of reduced growth on larval survival and subsequently on population growth. Developmental delays are less detrimental in species with longer and less synchronous larval periods. All six species were most sensitive to changes in first-year survival, and damping ratios were generally a good indicator of resilience to perturbations in both larval survival and fecundity. Further identification of species and population-level vulnerabilities can improve the evaluation of sublethal effects in relevant context for ERA. PMID- 29182970 TI - Time to continuous electroencephalogram in repeated admissions to the pediatric intensive care unit. AB - PURPOSE: Describe timing from intensive care unit (ICU) admission to initiation of continuous electroencephalogram (cEEG) in repeated ICU admissions. METHOD: We performed a retrospective observational study in pediatric patients who underwent repeated ICU admissions with cEEG from 2011 to 2013. The main outcome measure was time from ICU admission to cEEG. RESULTS: There were 41 patients (54% males) with at least 2 ICU admissions with cEEG (median (p25-p75) age at first admission: 3.3 (0.3-8.4) years, at second admission: 3.9 (1.1-9.4) years), 7 patients (57% males, 9.9 (2.9-11.5) years) with at least 3 ICU admissions, and 5 patients (60% males, 10.1 (4-10.5) years) with at least 4 ICU admissions. One patient had 21 ICU admissions. The median (p25-p75) time from ICU admission to cEEG was not different during the first and second ICU admissions [10.7 (1.9-22.9) hours versus 13 (0.2-36.7) hours; p=0.908]. Among patients with electrographic seizures on first admission, time to cEEG was not different during the first and second admissions [7.9 (0.5-23.4) hours versus 14.5 (-2 to 44.5) hours; p=0.636]. Among patients with status epilepticus during the first admission, time to cEEG was not different between the first and second admissions [15.3 (9-79) hours versus 40.7 (19.3-42.6) hours; p=0.75]. CONCLUSIONS: The time from ICU admission to the initiation of cEEG did not decrease in second or subsequent ICU admissions, even in patients with seizures or status epilepticus on the first admission. PMID- 29182971 TI - Detection and attribution of nitrogen runoff trend in China's croplands. AB - Reliable detection and attribution of changes in nitrogen (N) runoff from croplands are essential for designing efficient, sustainable N management strategies for future. Despite the recognition that excess N runoff poses a risk of aquatic eutrophication, large-scale, spatially detailed N runoff trends and their drivers remain poorly understood in China. Based on data comprising 535 site-years from 100 sites across China's croplands, we developed a data-driven upscaling model and a new simplified attribution approach to detect and attribute N runoff trends during the period of 1990-2012. Our results show that N runoff has increased by 46% for rice paddy fields and 31% for upland areas since 1990. However, we acknowledge that the upscaling model is subject to large uncertainties (20% and 40% as coefficient of variation of N runoff, respectively). At national scale, increased fertilizer application was identified as the most likely driver of the N runoff trend, while decreased irrigation levels offset to some extent the impact of fertilization increases. In southern China, the increasing trend of upland N runoff can be attributed to the growth in N runoff rates. Our results suggested that increased SOM led to the N runoff rate growth for uplands, but led to a decline for rice paddy fields. In combination, these results imply that improving management approaches for both N fertilizer use and irrigation is urgently required for mitigating agricultural N runoff in China. PMID- 29182973 TI - Diet-specific trophic transfer of mercury in tilapia (Oreochromis niloticus): Biodynamic perspective. AB - This study tested the hypothesis that different diets could modulate mercury (Hg) trophic transfer by concurrently altering the transfer of energy (in terms of growth) and transfer of Hg (in terms of biodynamic process). Firstly, we conducted a 40-d laboratory bioaccumulation experiment, in which tilapia (Oreochromis niloticus) was exposed to inorganic mercury (Hg[II]) and methylmercury (MeHg) via feeding on three distinct diets (macrophyte, freshwater shrimp, and commercial pellets) at a fixed ingestion rate of 0.065 g g-1 d-1. During the dietary exposure period, tilapia exhibited Hg species- and diet dependent Hg trophic transfer patterns and diet-specific growth rates. We then employed a biokinetic model to assess how diet-specific biodynamics and/or diet specific growth rates modulated the overall Hg bioaccumulation and trophic transfer. The diet-specific assimilation efficiencies (AEs) were monitored using radioisotope technique, and the determined AEs of Hg(II) (8.6%-29.7%) varied by 3.5 times among diets whereas the MeHg AEs (94.4%-97.1%) were not affected. The biokinetic modeling further revealed that Hg(II) trophic transfer in tilapia was controlled by the diet-specific AEs, while MeHg trophic transfer was governed by the diet-specific growth rates. Specifically, a diet-derived high growth rate reduced the MeHg trophic transfer in pellets-fed tilapia, and the overall accumulated MeHg level in fish was under the control of both somatic growth dilution and dietary MeHg influx. Moreover, we observed that the Hg levels (mainly as MeHg) in fast-growing farmed tilapia were significantly lower than wild-living tilapia after 100 d exposure in the field, attributed to somatic growth dilution (SGD). Both the laboratory and field study therefore demonstrated the importance of diet-derived SGD in modulating mercury trophic transfer in aquatic food webs. PMID- 29182972 TI - Endocrine disruption and differential gene expression in sentinel fish on St. Lawrence Island, Alaska: Health implications for indigenous residents. AB - People living a subsistence lifestyle in the Arctic are highly exposed to persistent organic pollutants, including polychlorinated biphenyls (PCBs). Formerly Used Defense (FUD) sites are point sources of PCB pollution; the Arctic contains thousands of FUD sites, many co-located with indigenous villages. We investigated PCB profiles and biological effects in freshwater fish (Alaska blackfish [Dallia pectoralis] and ninespine stickleback [Pungitius pungitius]) living upstream and downstream of the Northeast Cape FUD site on St. Lawrence Island in the Bering Sea. Despite extensive site remediation, fish remained contaminated with PCBs. Vitellogenin concentrations in males indicated exposure to estrogenic contaminants, and some fish were hypothyroid. Downstream fish showed altered DNA methylation in gonads and altered gene expression related to DNA replication, response to DNA damage, and cell signaling. This study demonstrates that, even after site remediation, contaminants from Cold War FUD sites in remote regions of the Arctic remain a potential health threat to local residents - in this case, Yupik people who had no influence over site selection and use by the United States military. PMID- 29182974 TI - Suspect screening and non-targeted analysis of drinking water using point-of-use filters. AB - Monitored contaminants in drinking water represent a small portion of the total compounds present, many of which may be relevant to human health. To understand the totality of human exposure to compounds in drinking water, broader monitoring methods are imperative. In an effort to more fully characterize the drinking water exposome, point-of-use water filtration devices (Brita(r) filters) were employed to collect time-integrated drinking water samples in a pilot study of nine North Carolina homes. A suspect screening analysis was performed by matching high resolution mass spectra of unknown features to molecular formulas from EPA's DSSTox database. Candidate compounds with those formulas were retrieved from the EPA's CompTox Chemistry Dashboard, a recently developed data hub for approximately 720,000 compounds. To prioritize compounds into those most relevant for human health, toxicity data from the US federal collaborative Tox21 program and the EPA ToxCast program, as well as exposure estimates from EPA's ExpoCast program, were used in conjunction with sample detection frequency and abundance to calculate a "ToxPi" score for each candidate compound. From ~15,000 molecular features in the raw data, 91 candidate compounds were ultimately grouped into the highest priority class for follow up study. Fifteen of these compounds were confirmed using analytical standards including the highest priority compound, 1,2 Benzisothiazolin-3-one, which appeared in 7 out of 9 samples. The majority of the other high priority compounds are not targets of routine monitoring, highlighting major gaps in our understanding of drinking water exposures. General product-use categories from EPA's CPCat database revealed that several of the high priority chemicals are used in industrial processes, indicating the drinking water in central North Carolina may be impacted by local industries. PMID- 29182975 TI - Adverse events of Dupilumab in adults with moderate-to-severe atopic dermatitis: A meta-analysis. AB - BACKGROUND: Dupilumab, a fully human monoclonal antibody against interleukin-4 receptor alpha, inhibits the signals of interleukin-4 and interleukin-13, and has also shown significant efficacy in patients with moderate-to-severe atopic dermatitis (AD), while the effect of it on adverse events remains controversial. OBJECTIVE: To assess the influence of dupilumab on adverse events in adults with moderate-to-severe AD. METHOD: Randomised controlled trials (RCTs) that compared dupilumab with a placebo for patients with moderate-to-severe AD were searched in the MEDLINE, EMBASE, Web of Science and Cochrane databases. The outcome of the study was the incidence of adverse events during the observation period. RESULTS: Eight RCTs were analysed in this study. Meta-analysis showed that patients treated with dupilumab had a lower risk of skin infection (risk ratio [RR] 0.54; 95% confidence interval [CI] 0.42-0.69) and exacerbation of AD (RR 0.44, 95% CI 0.34-0.59), but had a higher risk of injection-site reaction (RR 2.24, 95% CI 1.68-2.99), headache (RR 1.47, 95% CI 1.05-2.06), and conjunctivitis (RR 2.64, 95% CI 1.79-3.89) than did patients treated with a placebo. Nasopharyngitis, urinary tract infection, upper respiratory tract infection, and herpes virus infection were found balanced in dupilumab groups and placebo groups. CONCLUSION: Dupilumab moderately reduced the risk of skin infection and the exacerbation of AD, slightly increased the risk of headache, and moderately increased the risk of injection-site reaction and conjunctivitis, but had little effect on other infections in adults with moderate-to-severe AD.

AB - As recreational visitation to the Sonoran Desert increases, the concern of scientists, managers and advocates who manage its natural resources deepens. Although many studies have been conducted on trampling of undisturbed vegetation and the effects of trails on adjacent plant and soil communities, little such research has been conducted in the arid southwest. We sampled nine 450-m trail segments with different visitation levels in Scottsdale's McDowell Sonoran Preserve over three years to understand the effects of visitation on soil erosion, trailside soil crusts and plant communities. Soil crust was reduced by 27-34% near medium and high use trails (an estimated peak rate of 13-70 visitors per hour) compared with control plots, but there was less than 1% reduction near low use trails (peak rate of two to four visitors per hour). We did not detect soil erosion in the center 80% of the trampled area of any of the trails. The number of perennial plant species dropped by less than one plant species on average, but perennial plant cover decreased by 7.5% in trailside plots compared with control plots 6 m off-trail. At the current levels of visitation, the primary management focus should be keeping people on the originally constructed trail tread surface to reduce impact to adjacent soil crusts. PMID- 29182977 TI - Decentralised black water treatment by combined auto-thermal aerobic digestion and ammonia - A pilot study optimising treatment capacity. AB - Partial heating of black water by auto-thermal aerobic digestion was combined with the addition of 1% w/w urea and monitoring of pathogens and indicator organisms over a 21-day period. After initial mixing, the 160 m3 black water (60 m3 heated and 100 m3 non-heated) was left undisturbed. The urea was confirmed to be fully degraded into ammonia (5.1 g N L-1) first after 14 days, while the pH stabilised at around 9.2 after one week. The initial temperature of 17 degrees C fell by 6 degrees C during the study. E. coli and Salmonella spp., which are sensitive to ammonia, were inactivated during the first few days of the study, despite the urea only being partly hydrolysed. At day 14, f-RNA bacteriophages could also no longer be detected. The more persistent somatic coliphages, Enterococcus spp. and Ascaris eggs, showed significant but slow inactivation. The treatment proved to be efficient with regards to salmonella, which is a target pathogen in the Swedish context, but for parasite egg inactivation a higher temperature was required. The treatment would benefit from more frequent stirring to speed up the hydrolysis of urea and thus improve treatment efficiency. The alternative treatment scheme could increase capacity by 2.4 times, albeit with a 40% higher cost per volume due to the increased use of urea.

AB - The desalination and treatment of tannery unhairing wastewater by electrodialysis (ED) is investigated in this research in order to separate, concentrate, recover and reuse low molecular weight charged species (S2-, HS-, OH-, Cl-, Ca2+, Na+ and amino acids), and to separate proteins and recycle treated water. Therefore, a novel electrodialysis membrane configuration was proposed. This was based on a double anti-fouling membrane. The ED anion exchange membrane (AEM), which is very sensitive to organic fouling, was protected by an ultra filtration membrane impermeable to the negatively charged proteins that could not reach the AEM surface. The experimental results were quite promising, and in spite of only one desalination compartment ED cell; the demineralization efficiency was 56 +/- 1.25% (5.5-2.4 mS/cm), with a sensitive removal of sulphide, calcium and chloride. The organic matter (protein, peptides...) was isolated in the dilute compartment. The most important result was the total absence of membrane fouling. The experimental results remarkably proved the initial hypothesis, and suggested promising solutions for industrial pollution, where the membrane processes have never been successful. PMID- 29182979 TI - An atmospheric vulnerability assessment framework for environment management and protection based on CAMx. AB - This paper presents an atmospheric vulnerability assessment framework based on CAMx that should be helpful to assess potential impacts of changes in human, atmospheric environment, and social economic elements of atmospheric vulnerability. It is also a useful and effective tool that can provide policy guidance for environmental protection and management to reduce the atmospheric vulnerability. The developed framework was applied to evaluate the atmospheric environment vulnerability of 13 cities in the Beijing-Tianjin-Hebei (BTH) region for verification. The results indicated that regional disparity of the atmospheric vulnerability existed in the study site. More specifically, the central and southern regions show more atmospheric environment vulnerability than the northern regions. The impact factors of atmospheric environment vulnerability in the BTH region mainly derived from increasing population press, frequently unfavorable meteorological conditions, extensive economic growth of secondary industry, increased environmental pollution, and accelerating population aging. The framework shown in this paper is an interpretative and heuristic tool for a better understanding of atmospheric vulnerability. This framework can also be replicated at different spatial and temporal scales using context-specific datasets to straightly support environmental managers with decision-making. PMID- 29182980 TI - The influence of perforation of foil reactors on greenhouse gas emission rates during aerobic biostabilization of the undersize fraction of municipal wastes. AB - The opinion, that the use of foil reactors for the aerobic biostabilization of municipal wastes is not a valid method, due to vulnerability to perforation, and risk of uncontrolled release of exhaust gasses, was verified. This study aimed to determine the intensity of greenhouse gas (GHG) emissions to the atmosphere from the surface of foil reactors in relation to the extent of foil surface perforation. Three scenarios were tested: intact (airtight) foil reactor, perforated foil reactor, and torn foil reactor. Each experimental variant was triplicated, and the duration of each experiment cycle was 5 weeks. Temperature measurements demonstrated a significant decrease in temperature of the biostabilization in the torn reactor. The highest emissions of CO2, CO and SO2 were observed at the beginning of the process, and mostly in the torn reactor. During the whole experiment, observed emissions of CO, H2S, NO, NO2, and SO2 were at a very low level which in extreme cases did not exceed 0.25 mg t-1.h-1 (emission of gasses mass unit per waste mass unit per unit time). The lowest average emissions of greenhouse gases were determined in the case of the intact reactor, which shows that maintaining the foil reactors in an airtight condition during the process is extremely important. PMID- 29182981 TI - Evolution of various fractions during the windrow composting of chicken manure with rice chaff. AB - Different fractions during the 85-day windrow composting were characterized based on various parameters, such as physiochemical properties and hydrolytic enzyme activities; several technologies were used, including spectral scanning techniques, confocal laser scanning microscopy (CLSM) and 13C Nuclear Magnetic Resonance Spectroscopy (13C NMR). The evaluated parameters fluctuated strongly during the first 3 weeks which was the most active period of the composting process. The principal components analysis (PCA) results showed that four classes of the samples were clearly distinguishable, in which the physiochemical parameters were similar, and that the dynamics of the composting process was significantly influenced by C/N and moisture content. The 13C NMR results indicated that O-alkyl-C was the predominant group both in the solid and water soluble fractions (WSF), and the decomposition of O-alkyl-C mainly occurred during the active stage. In general, the various parameters indicated that windrow composting is a feasible treatment that can be used for the resource reuse of agricultural wastes. PMID- 29182982 TI - Moderate intermittent negative pressure increases invasiveness of MDA-MB-231 triple negative breast cancer cells. AB - BACKGROUND: To investigate the effect moderate intermittent negative pressure breast reconstructive model exerts on human triple negative breast cancer cell (TNBC) invasion and explore the related mechanism. METHODS: The human TNBC cell line MDA-MB-231 was used. Cells in external volume expansion (EVE) group were exposed to an intermittent -25 mmHg for 12 h; the pressure for non-EVE group was constantly 0 mmHg. In vivo, MDA-MB-231 cell suspensions were injected subcutaneously into dorsal skin of nude mice (n = 27 mice/group). Tumors on mice in EVE group received -25 mmHg suction 3 h/day; while mice in non-EVE group were under normal pressure. Cell invasion assay, ELISA, RT-PCR, western blot analysis and immunohistochemistry were used to evaluate the inflammation, epithelial mesenchymal transition (EMT) and angiogenesis between the two groups in both vitro and vivo experiments. RESULTS: MDA-MB-231 cells in the EVE group were more invasive and had higher expressions of IL-8 (30.02 +/- 10.44 pg/ml vs. 18.82 +/- 9.26 pg/ml, P < 0.05) and TNF-alpha (20.59 +/- 4.72 pg/ml vs. 14.10 +/- 3.36 pg/ml, P < 0.05) than the non-EVE group. Grafted MDA-MB-231 tumors in EVE group showed a more obvious epithelial-mesenchymal transition at 2 week and better angiogenesis at 2 and 4 week, respectively. CONCLUSION: Moderate intermittent negative pressure induces MDA-MB-231 cells to be more invasive. Future studies should figure out other effects this intervention may bring. Clinical studies should also be conducted to further evaluate its safety and optimize the clinical model. PMID- 29182984 TI - Bioaccessibilities and health implications of heavy metals in exposed-lawn soils from 28 urban parks in the megacity Guangzhou inferred from an in vitro physiologically-based extraction test. AB - This study focused on characterizing the oral bioaccessibilities and human health risks of eight heavy metals (Cd, Pb, Cr, Ni, Cu, Zn, Fe, and Mn) in surface exposed lawn soils from 28 urban parks in Guangzhou. The physiologically-based extraction test (PBET) method was used to assess bioavailability (in gastric and intestinal phases) and human health risk was assessed via statistical modelling (carcinogenic risk assessment, hazard quotients and hazard indices). Mean bioaccessibilities of Cd, Pb, Cr, Ni, Cu, Zn, Fe, and Mn from all soil samples were 50.90 +/- 17.67%, 5.81 +/- 1.67%, 7.12 +/- 3.24%, 17.91 +/- 18.34%, 11.93 +/ 2.88%, 34.33 +/- 10.02%, 1.68 +/- 0.48%, 26.71 +/- 5.06%, respectively. The concentrations of most heavy metals were higher in the gastric phase, except for Cr and Ni which remained higher in the intestinal phase. Principal component analysis revealed that the bioaccessibilities of the heavy metals could be split into three groupings, based on the urban park of soil origin. The carcinogenic risk probabilities for Pb and Cr were under the acceptable level (< 1 * 10-4) for both adults and children. The hazard quotient and hazard index values indicated no significant risk of non-carcinogenic effects to children or adults exposed to Guangzhou urban park soils. This research will help inform further risk assessment and management of heavy metal contaminants in urban environments. PMID- 29182985 TI - Assessment of metal pollution in the Lambro Creek (Italy). AB - This study assessed the effect of metal pollution in the Lambro Creek (Southern Italy). Water, sediment and biota were collected at six sampling sites (June) for metal concentration assessment (Cr, Cu, Ni, Pb and Zn). Sequential extraction was performed to determine the distribution of metals in different geochemical sediment fractions. The influence of pH and leaching time on the release of metals from sediment to the water column was investigated via remobilization tests. A battery of toxicity tests (Vibrio fischeri, Raphidocelis subcapitata, Phaeodactylum tricornutum, and Daphnia magna) with multi-endpoints (bioluminescence, growth inhibition, and immobilization) was used to determine the overall toxicity in sediment water extracts. The results showed that metals did not exceed the probable effect concentration levels, with Cr concentration exceeding the threshold effect concentration level at all sampling points except for the one closer to the source of the creek, suggesting potential negative effect on the biota. Considering the cumulative criterion unit, sediment contamination was moderate at all sampling sites, except for L3 and L5 where biota was exposed to a very high risk. With respect to sequential analysis, the most readily available fraction of metal can be generalised as Ni > Cr > Cu > Zn > Pb. For better understanding the fate of metals in the water-sediment environment, their biogeochemical cycles should also be investigated in small creeks including both fresh (watercourse) and saltwater (river mouth) sediments. PMID- 29182983 TI - Mammospheres of hormonal receptor positive breast cancer diverge to triple negative phenotype. AB - OBJECTIVES: This study aimed to characterize mammospheres from hormonal receptor (HR) positive and triple-negative breast cancer (TNBC), hypothesizing a differential profile of CSC and differentiation markers, and a stemness enrichment when successive sphere forming-protocols are performed. METHODS: Breast cancer cells MCF-7 and HCC1806 were submitted to sphere-forming protocols. The first sphere generation (MS1) was cultured in adherent conditions (G1). This procedure was repeated and generations of mammospheres (MS1, MS2, and MS3) and sphere-derived cells in adherent conditions (G1, G2, and G3) were obtained. The mammosphere forming capacity, self-renewal, area and doubling time were evaluated. Flow cytometry regarding CD133, CD24, and CD44 and western-blot regarding aldehyde dehydrogenase (ALDH), hormonal receptors and P53 expression was performed. RESULTS: Breast cancer cell lines harboured the capacity to form spheres, which originated derived adherent populations. The sphere-forming capacity was enhanced in HCC1806-MS3 compared to MS1. Self-renewal was higher in MCF-7 mammospheres, which also had an increased area. The putative CSC markers CD133 showed tendency to be enhanced in mammospheres but the CD44+/CD24-/low phenotype was not identified. The expression of ALDH was greater in mammospheres from MCF-7 and HCC1806 than in the respectively derived adherent cells. The expression of oestrogen receptor (ER)-alpha, progesterone receptor (PR) and P53 decreased in MCF-7 spheres. ER-beta expression was lower in mammospheres from both cell lines compared with parental and derived adherent populations. CONCLUSIONS: Loss of HR and P53 expression in HR-positive mammospheres evidences the minor population of CSC which shares characteristics with the TNBC phenotype. PMID- 29182986 TI - Amelioration of cadmium-induced testes' damage in rats by the bone marrow mesenchymal stem cells. AB - Cadmium (Cd) and its compounds are highly toxic to virtually all organ systems of the mammals. Cd-induced testicular injuries have been reported in various animal species, using different protocols. The self-renewal capacity and the ability to generate different specialized cell types make the mesenchymal stem cells (MSCs) one of the ideal choices for restoring tissue damages of various etiologies. The use of bone marrow-derived MSCs (BM-MSCs) is among the most recent strategies to repair the Cd-induced testicular damage, but empirical studies in this regard are largely missing. Keeping in view the CD-induced testicular damage and the suggested restorative functions of BM-MSCs, the objectives of the current study were twofold: to induce testicular injury in Sprague-Dawley (SD) rats by a single intraperitoneal (i.p.) 2mg/kg Cd injection; and to study the reparative potential of BM-MSCs in Cd-induced testicular damage in adult male rats. The SD rats were randomly divided into three groups (n = 10 each): control (untreated), Cd-group (i.p. 2mg/kg Cd), and Cd+SC group (i.p. 2mg/kg Cd plus two intravenous doses of 1 * 106 BM-MSCs via penile vein). After four weeks, Cd-group showed a significantly lower (p < 0.05) weight-gain, sperm count, and sperm viability, as well as led to testicular atrophy, necrosis, fibrosis, calcification, and marked perivascular lymphocytic infiltration, as compared to the untreated controls. As hypothesized, the rats exposed to Cd, but treated with BM-MSCs (Cd+SC group), showed a lesser degree of Cd-induced damage. In conclusion, the findings of current investigation indicate a reversal of Cd-induced testicular injury by BM-MSCs. The study supports the previously suggested notion that BM-MSCs can repair the Cd-induced testes' damage in rats. PMID- 29182987 TI - Lipoprotein(a) and abdominal aortic aneurysm risk: The Atherosclerosis Risk in Communities study. AB - BACKGROUND AND AIMS: No prospective study has investigated whether elevated lipoprotein(a) concentrations are associated with an increased risk of abdominal aortic aneurysm (AAA). We aimed to prospectively investigate this association. METHODS: In 1987-1989, the Atherosclerosis Risk in Communities study measured plasma lipoprotein(a) in 13,683 participants aged 45-64 years, without a history of AAA surgery. We followed them for incident, clinical AAA events through 2011. RESULTS: During the 272,914 person-years of follow-up, over a median of 22.6 years, we documented 505 incident AAA events. The age-, sex-, and race-adjusted model showed that individuals in the highest quintile of plasma lipoprotein(a) had an increased risk of AAA. Further adjustment for the other potential confounding factors, including other plasma lipids (high- and low-density lipoprotein cholesterol and triglyceride concentrations), attenuated the association, but individuals in the highest versus lowest quintile of plasma lipoprotein(a) still had a significantly increased risk of AAA [hazard ratio (95% confidence interval): 1.57 (1.19-2.08)]. Interaction testing suggested no difference in the associations for whites and African Americans (p for interaction = 0.96). A restricted cubic spline analysis demonstrated a positive dose-response relation of plasma lipoprotein(a) with AAA, with a steep increase in AAA risk above the 75th percentile (p for overall association = 0.0086, p for non-linear association = 0.097). CONCLUSIONS: In this population-based cohort study, elevated lipoprotein(a) concentrations were independently associated with an increased risk of AAA. The association reflected a threshold of increased AAA risk at high lipoprotein(a) concentrations, rather than a steady monotonic association. PMID- 29182988 TI - Elevated circulating TGF-beta is not the cause of increased atherosclerosis development in biglycan deficient mice. AB - BACKGROUND AND AIMS: Vascular biglycan contributes to atherosclerosis development and increased biglycan expression correlates with increased atherosclerosis. However, mice deficient in biglycan have either no reduction in atherosclerosis or an unexpected increase in atherosclerosis. Biglycan deficient mice have systemically elevated TGF-beta, likely due to lack of sequestration of TGF-beta in the extracellular matrix. The purpose of this study was to determine if prevention of TGF-beta elevations in biglycan deficient mice affected atherosclerosis development. METHODS: Biglycan deficient mice were crossed to Ldlr deficient mice. Diabetes was induced via streptozotocin and all mice were fed a high cholesterol diet. Diabetic biglycan wild type and biglycan deficient Ldlr deficient mice were injected with the TGF-beta neutralizing antibody 1D11 or the irrelevant control antibody 13C4. RESULTS: Biglycan deficient mice had significantly elevated plasma TGF-beta levels, which was further increased by diabetes, and significantly increased atherosclerosis. There was a significant correlation between TGF-beta concentrations and atherosclerosis. However, despite nearly complete suppression of plasma TGF-beta levels in mice treated with the TGF-beta neutralizing antibody 1D11, there was no significant difference in atherosclerosis between mice with elevated TGF-beta levels and mice with suppressed TGF-beta levels. CONCLUSIONS: The increased atherosclerosis in biglycan deficient mice does not appear to be due to elevations in TGF-beta. PMID- 29182989 TI - Investigations for radiculopathy: The patient perspective. A qualitative, interpretative inquiry. AB - BACKGROUND: Clinical guidelines recommend that investigations, such as magnetic resonance imaging, are offered only when likely to change management. Meanwhile, the optimal process of diagnosing radiculopathy remains uncertain and, in clinical practice, differences of opinion can occur between patient and clinician regarding the perceived importance of investigations. OBJECTIVES: To explore peoples' experiences of investigations and the effect of concordance between clinical presentation and investigation findings. METHODS: In this qualitative study, 14 participants who had recently undergone investigations for a clinical presentation of radiculopathy were purposively recruited from an NHS, Primary Care Service in the United Kingdom. Based on the principles of interpretative phenomenological analysis, individual, semi-structured interviews were recorded and transcribed verbatim. Data were managed using a framework approach and analysed thematically. FINDINGS: Although people reported wanting investigations to understand the cause of symptoms and inform management, access to them was reported to be difficult and protracted. When investigations revealed potentially relevant findings, people experienced relief, validation, empowerment and decisive decision-making. Disappointment emerged, however, regarding treatment options and waiting times, and long-term prognosis. When investigations failed to identify relevant findings, people were unable to make sense of their symptoms, relinquish their search to identify the cause, or to move forward in their management. CONCLUSIONS: This study provides the first reported in-depth interpretation of peoples' experience of undergoing investigations specifically for radiculopathy. Important implications have been identified for: investigation referral criteria; shared-decision-making; information sharing and managing expectations and disappointment. CLINICALTRIALS. GOV REFERENCE: UOS-2307-CR. PMID- 29182990 TI - Patterns of responses in metastatic NSCLC during PD-1 or PDL-1 inhibitor therapy: Comparison of RECIST 1.1, irRECIST and iRECIST criteria. AB - BACKGROUND: Immune checkpoint inhibitors are an important tool in the therapeutic strategy against metastatic non-small cell lung cancer (NSCLC); however, radiological evaluation is challenging due to the emergence of atypical patterns of responses. Several evaluation criteria have been proposed, such as the Response Evaluation Criteria in Solid Tumours (RECIST), version 1.1, immune related RECIST (irRECIST) and iRECIST, but have not been systematically compared in a homogeneous population. PATIENTS AND METHODS: We conducted a monocentric retrospective analysis of consecutive advanced NSCLC patients treated with an anti-programmed cell death-1 or anti-program death-ligand 1. Response patterns and the discordance between RECIST 1.1, irRECIST and iRECIST guidelines were described, and associations of response patterns and clinical outcome were explored. RESULTS: Overall, 160 patients treated between February 2013 and October 2016 were included. Atypical responses were observed in 20 patients (13%), including eight pseudoprogressions (PsPDs) (5%) and 12 dissociated responses (8%). Thirteen of the 20 patients demonstrated clinical benefit. Per the RECIST 1.1, 37 patients (23%) showed an objective response or stable disease, and 123 patients (77%) exhibited progression. Eighty progressive patients were assessable for irRECIST and iRECIST: 15 patients were assessed differently; however, only three (3.8%) mismatches with a theoretical impact on the therapeutic decision were identified. Patients with PsPD or dissociated response had higher overall survival than patients with true progression. CONCLUSION: Atypical responses (PsPD/dissociated response) occurred in 13% of NSCLC patients under immune checkpoint inhibitors. Based on survival analyses, the RECIST 1.1 evaluation underestimated the benefit of immune checkpoint inhibitors in 11% of the progressive patients. Immune-related RECIST and iRECIST identified these unconventional responses, with a 3.8% discrepancy rate. PMID- 29182991 TI - Influences of feedstock type and process variables on hydrochar properties. AB - In this study, the effect of process variables, such as temperature, biomass:water ratio and reaction time, in hydrothermal carbonization (HTC) has been studied for different type biomasses. Response surface methodology was used to study the influence of each factors as well as their combined interactive effect on the mass yield and energy density of hydrochars. The results showed that the temperature and time were significant factors effecting the mass yield and energy densification ratio in HTC of the sunflower stalk and algae, whereas temperature was only significant factor in HTC of poultry litter. The biomass:water ratio was found insignificant for all tested biomasses. In addition, the fuel properties of hydrochars were compared with the properties of biochar derived from torrefaction at 300 degrees C. The results showed that for all tested biomass, the biochars had lower volatile matter and fixed carbon than hydrochars. PMID- 29182992 TI - Process design and economics of a flexible ethanol-butanol plant annexed to a eucalyptus kraft pulp mill. AB - This work proposes a strategy, from a process design standpoint, for pulp companies to enter the Brazilian ethanol market. The flexible plant converts eucalyptus-derived glucose to either ethanol or butanol (according to market conditions) and xylose only to butanol production. Depending on the biomass pretreatment technology, Monte Carlo simulations showed that the Net Present Value (NPV) of the flexible plant increases by 20-28% in relation to an ethanol dedicated plant. Whereas the lower costs of the steam explosion technology turns the investment more attractive (NPV = 184 MMUSD; IRR = 29%), the organosolv technology provides better flexibility to the plant. This work also shows that excessive power consumption is a hurdle in the development of flash fermentation technology chosen for the flexible plant. These results indicate that conventional batch fermentation is preferable if the enzymatic hydrolysis step operates with solids loading up to 20 wt%. PMID- 29182993 TI - Lymphocyte count in peripheral blood is not associated with the level of clinical response to treatment with fingolimod. AB - BACKGROUND: Fingolimod is an efficient and safe drug for treating relapsing remitting multiple sclerosis (RRMS). In vivo, fingolimod is phosphorylated and binds to "sphingosine-1-phosphate"(S1P) receptors that are expressed in a wide range of cells, including lymphocytes. Under the effect of fingolimod, lymphocytes are retained in lymphoid tissues through the regulation of S1P1 receptors. The aim of the present study was to assess whether the degree of lymphopenia was correlated to the positive treatment response of RRMS patients with fingolimod. METHODS: Data was sourced from the MSBase Registry. Patients were divided into two groups, according to the lymphocyte count on peripheral blood examination. Annualized Relapse Rate (ARR), time to first relapse and time to six-month confirmed disability progression were compared between groups. RESULTS: Group one consisted of 202 patients who reached 750 lymphocytes/mm3 during treatment while the comparison group two included 101 patients who never reached less than 1000 lymphocytes/mm3 in peripheral blood during the observation period. There were no differences between groups in ARR, time to first relapse or time to six-month confirmed disability progression. CONCLUSION: The degree of lymphopenia in peripheral blood was not associated to the positive treatment response of fingolimod in RRMS patients. PMID- 29182994 TI - Motor fatigability in persons with multiple sclerosis: Relation between different upper limb muscles, and with fatigue and the perceived use of the arm in daily life. AB - BACKGROUND: Motor fatigability is increasingly acknowledged in persons with MS (pwMS). It is unknown whether fatigability is generalized across upper limb muscles and relates to fatigue and perceived difficulties in upper limb use. METHODS: This observational case-controlled study included twenty PwMS (median EDSS = 3, range 1.5-6.5) and twenty healthy controls who performed 30" sustained maximal muscle contractions for index finger abduction, hand grip, elbow flexion and shoulder abduction. A static fatigue index (SFI) was calculated to assess motor fatigability for each muscle group. PwMS completed the Fatigue Severity Scale (FSS) and Modified Fatigue Index Scale (MFIS), to quantify severity and perceived impact of fatigue and the Manual Ability Measure (MAM-36) reflecting perceived difficulty in using the upper limbs. Comparisons between groups and muscles was made by t-tests. Associations between outcomes were calculated with correlation coefficients. RESULTS: Fatigue was highest in pwMS. PwMS showed preserved muscle strength and a greater motor fatigability in elbow flexors compared to healthy controls. SFI of elbow flexors and shoulder abductors were associated, and contributed to FSS and MFIS. SFI of elbow flexors and finger abductors predicted half of the variation in MAM-36. CONCLUSION: Increased motor fatigability was only present in elbow flexors of PwMS, indicating that expression of motor fatigability is not generalized. Fatigability was associated with perceived fatigue (impact) and daily life upper limb use. Results are preliminary given the small sample size with predominantly persons with mild MS. PMID- 29182995 TI - Cocaine-induced multifocal leukoencephalopathy mimicking Balo's concentric sclerosis: A 2-year follow-up with serial imaging of a single patient. AB - Cocaine abuse may cause stroke, metabolic or multifocal inflammatory leukoencephalopathy. We described a patient with cocaine abuse who presented with Balo's type acute multifocal leukoencephalopathy. Magnetic Resonance Imaging (MRI) of the brain showed onion like patchy concentric ring enhancement on T1 weighted MRI with gadolinium. Balo's Concentric Sclerosis like radiological findings related to cocaine has not been reported. Levamisole is now frequently used as an ingredient in cocaine and may cause leukoencephalopathy. It is recommended to check urine levamisole levels in patients with cocaine-induced leukoencephalopathy with or without mimicking Balo's Concentric Sclerosis. On the other hand, it is also possible that the cocaine use was coincidental and this was a demyelinating case arising de novo in patient who uses cocaine. PMID- 29182996 TI - Distinguishing among multiple sclerosis fallers, near-fallers and non-fallers. AB - BACKGROUND: Fall rates among adults with multiple sclerosis are consistently greater than 50%, but near-falls (i.e. a trip or stumble) are often undocumented. Furthermore, little is known about the circumstances surrounding fall and near fall events. The purpose of this study was to examine the similarities and differences among non-fallers, near-fallers and fallers with multiple sclerosis, including the circumstances that surround falls and near-falls. METHODS: In a single visit, 135 multiple sclerosis participants completed the Hopkins Falls Grading Scale, a custom questionnaire investigating circumstances surrounding falls and near-falls, and performed the Timed Up and Go and Timed 25-Foot Walk tests. Mann-Whitney tests were used to examine differences between fallers, near fallers and non-fallers. Multiple logistic regression with AIC criterion was used to examine associations of circumstances with the odds of falling vs. near falling. Cumulative odds ordinal logistic regression was used to analyze the association between each of the walking tests and the susceptibility of the individual for falls or near-falls. RESULTS: 30% of individuals reported falls, while 44% reported near-falls over a 1-year period. Non-fallers completed the walking tests more quickly than near-fallers (p < 0.0045), and fallers (p < 0.0001); near-fallers and fallers demonstrated similar motor profiles. Individuals were more likely to sustain a fall rather than a near-fall under the following circumstances: transferring outside the home (p = 0.015) and tripping over an obstacle (p = 0.025). Performing 1-second slower on the walking tests increased the odds of a history of a fall by 6-20%. CONCLUSION: Near-falls occur commonly in individuals with MS; near-fallers and fallers reported similar circumstances surrounding fall events and demonstrated similar performance on standard timed walking tests. Clinicians monitoring individuals with MS should consider evaluation of the circumstances surrounding falls in combination with quantitative walking measures to improve determination of fall risk and appropriate rehabilitation interventions. PMID- 29182997 TI - Bioanalytical methods for the quantification of hydromorphone, fentanyl, norfentanyl, morphine, morphine-3beta-glucuronide and morphine-6beta-glucuronide in human plasma. AB - The aim of this study was to develop an assay for the quantification of hydromorphone, morphine, fentanyl and the metabolites norfentanyl, morphine-3beta glucuronide and morphine-6beta-glucuronide in human plasma to support pharmacokinetic studies investigating the large interpatient variability in response to opioid treatment. For the quantitation of hydromorphone, morphine, fentanyl and its metabolite norfentanyl aliquots of 200MUL human potassium EDTA plasma were deproteinized with deuterated internal standards in a mixture of acetonitrile and acetone, followed by a liquid-liquid extraction with 4% ammonium hydroxide and ethyl acetate. Morphine-3beta-glucuronide and morphine-6beta glucuronide were extracted by a solid phase extraction using 10mM ammonium carbonate pH 8.8 and a deuterated internal standards solution. Morphine, hydromorphone, fentanyl and norfentanyl were separated on an Aquity UPLC(r) BEH C18 column 1.7MUm, 100mm*2.1mm at 50 degrees C. Separation, was achieved on a gradient of methanol with an overall run time of 6min. The compounds were quantified by triple-quadrupole mass spectrometry in the positive ion electrospray ionization mode. Morphine-3beta-glucuronide and morphine-6beta glucuronide were separated on a VisionHT C18-P; 3MUm 2.1*50mm, column at 40 degrees C on a gradient of acetonitrile, with an overall run time of 10min. Both methods were precise and accurate, with within-run and between-run precisions within acceptable limits and accuracy ranging from 84.0 to 105.5%. The methods were successfully applied to support clinical pharmacological studies in patients treated with opioids for the treatment of moderate to severe cancer-related pain.

AB - Feverfew (Tanacetum parthenium L.) as a perennial herb has been known for centuries due to its medicinal properties. The main sesquiterpene lactone, parthenolide is considered to be responsible for the migraine prophylactic effect, however the pharmacological benefits of the lipophilic flavonoid components can not be neglected. Supercritical fluid extraction (7% ethanol, 22MPa, 64 degrees C) was carried out on the leaves of Tanacetum parthenium L. from which the presence of methylated flavonoids beside parthenolide and other sesquiterpene lactones were indicated by preliminary LC-MS analyses. Specific Parallel Artificial Membrane Permeability Assay (PAMPA) was applied to identify the components capable to cross the Blood-Brain Barrier (BBB). Three lipophilic flavonoids were detected on the acceptor side, that were isolated (Prep-HPLC) and identified as sudachitin, aceronin and nevadensin (LC-MS/MS, NMR). These flavonoids were also characterized individually by PAMPA-BBB model. The presence of sudachitin and nevadensin was proven in the Asteraceae family, but neither of the three flavonoids were reported in Tanacetum parthenium L.

AB - Hemp seed oil from Cannabis sativa L. is a very rich natural source of important nutrients, not only polyunsaturated fatty acids and proteins, but also terpenes and cannabinoids, which contribute to the overall beneficial effects of the oil. Hence, it is important to have an analytical method for the determination of these components in commercial samples. At the same time, it is also important to assess the safety of the product in terms of amount of any psychoactive cannabinoid present therein. This work presents the development and validation of a highly sensitive, selective and rapid HPLC-UV method for the qualitative and quantitative determination of the main cannabinoids, namely cannabidiolic acid (CBDA), tetrahydrocannabinolic acid (THCA), cannabidiol (CBD), tetrahydrocannabinol (THC), cannabinol (CBN), cannabigerol (CBG) and cannabidivarin (CBDV), present in 13 commercial hemp seed oils. Moreover, since decomposition of cannabinoid acids generally occurs with light, air and heat, decarboxylation studies of the most abundant acid (CBDA) were carried out in both open and closed reactor and the kinetics parameters were evaluated at different temperatures in order to evaluate the stability of hemp seed oil in different storage conditions.

AB - Recently, the bottom-up assembly of a synthetic cell has emerged as a daring novel approach that can be expected to have major impact in generating fundamental insight in the organization and function of actual biological cells, as well as in stimulating a broad range of applications from drug delivery systems to chemical nanofactories. A crucial feature of any such synthetic cell is the architectural scaffold that defines its identity, compartmentalizes its inner content, and serves as a protective and selective barrier against its environment. Here we review a variety of potential scaffolds for building a synthetic cell. We categorize them as membranous structures (liposomes, fatty acid vesicles, polymersomes), emulsions (droplets and colloidosomes), and membrane-less coacervates. We discuss recent advances for each of them, and explore their salient features as candidates for designing synthetic cells. PMID- 29183002 TI - An MR/MRI compatible core holder with the RF probe immersed in the confining fluid. AB - An open frame RF probe for high pressure and high temperature MR/MRI measurements was designed, fabricated, and tested. The open frame RF probe was installed inside an MR/MRI compatible metallic core holder, withstanding a maximum pressure and temperature of 5000 psi and 80 degrees C. The open frame RF probe was tunable for both 1H and 19F resonance frequencies with a 0.2 T static magnetic field. The open frame structure was based on simple pillars of PEEK polymer upon which the RF probe was wound. The RF probe was immersed in the high pressure confining fluid during operation. The open frame structure simplified fabrication of the RF probe and significantly reduced the amount of polymeric materials in the core holder. This minimized the MR background signal detected. Phase encoding MRI methods were employed to map the spin density of a sulfur hexafluoride gas saturating a Berea core plug in the core holder. The SF6 was imaged as a high pressure gas and as a supercritical fluid.

AB - Due to the inherently long relaxation time of 13C spins in diamond, the nuclear polarization enhancement obtained with dynamic nuclear polarization can be preserved for a time on the order of about one hour, opening up an opportunity to use diamonds as a new class of long-lived contrast agents. The present communication explores the feasibility of using 13C spins in directly hyperpolarized diamonds for MR imaging including considerations for potential in vivo applications.

PMID- 29183004 TI - Adaptive suppression of power line interference in ultra-low field magnetic resonance imaging in an unshielded environment. AB - Power-line harmonic interference and fixed-frequency noise peaks may cause stripe artifacts in ultra-low field (ULF) magnetic resonance imaging (MRI) in an unshielded environment and in a conductively shielded room. In this paper we describe an adaptive suppression method to eliminate these artifacts in MRI images. This technique utilizes spatial correlation of the interference from different positions, and is realized by subtracting the outputs of the reference channel(s) from those of the signal channel(s) using wavelet analysis and the least squares method. The adaptive suppression method is first implemented to remove the image artifacts in simulation. We then experimentally demonstrate the feasibility of this technique by adding three orthogonal superconducting quantum interference device (SQUID) magnetometers as reference channels to compensate the output of one 2nd-order gradiometer. The experimental results show great improvement in the imaging quality in both 1D and 2D MRI images at two common imaging frequencies, 1.3 kHz and 4.8 kHz. At both frequencies, the effective compensation bandwidth is as high as 2 kHz. Furthermore, we examine the longitudinal relaxation times of the same sample before and after compensation, and show that the MRI properties of the sample did not change after applying adaptive suppression. This technique can effectively increase the imaging bandwidth and be applied to ULF MRI detected by either SQUIDs or Faraday coil in both an unshielded environment and a conductively shielded room. PMID- 29183005 TI - Microarray Expression Profile of Circular RNAs in Plasma from Primary Biliary Cholangitis Patients. AB - BACKGROUND/AIMS: Circular RNAs (circRNAs) play a crucial role in the occurrence of several diseases, including autoimmune diseases. However, their role in primary biliary cholangitis (PBC) remains unclear. Here, we aimed to determine the circRNA expression profile in plasma from PBC patients and further explore the value of circRNA in diagnosing PBC. METHODS: CircRNA microarrays were used to determine circRNA expression profiles in plasma samples from 6 PBC patients and 6 healthy controls. Statistical analyses identified differentially expressed circRNAs, and these circRNAs were verified by qRT-PCR in 29 PBC patients and 30 healthy controls. MicroRNA (miRNA) target prediction software identified putative miRNA response elements (MREs), which were used to construct a map of circRNA miRNA interactions for the differentially expressed circRNAs. RESULTS: Our results indicated that there were 18 up-regulated and 4 down-regulated circular RNAs in the plasma from PBC patients compared with that from healthy individuals. Among the differentially expressed circRNAs, hsa_circ_402458 (P=0.0033), hsa_circ_087631 and hsa_circ_406329 (P=0.0185) were up-regulated, and hsa_circ_407176 (P=0.0066) and hsa_circ_082319 were down-regulated in the PBC group versus the healthy group as demonstrated by qRT-PCR. In particular, hsa_circ_402458 was significantly higher in PBC patients not receiving UDCA treatment than in PBC patients receiving UDCA treatment (P=0.0338). The area under the receiver operating characteristic curve for hsa_circ_402458 for diagnosing PBC was 0.710 (P=0.005). For hsa_circ_402458, two putative miRNA targets, hsa-miR-522-3p and hsa-miR-943, were predicted. CONCLUSIONS: circRNA dysregulation may play a role in PBC pathogenesis, and hsa_circ_402458 shows promise as a candidate biomarker for PBC. PMID- 29183006 TI - Health-Related Quality of Life in 536 Long-Term Prostate Cancer Survivors after Treatment with Leuprorelin Acetate: A Combined Retrospective and Prospective Analysis. AB - INTRODUCTION: We investigated the health-related quality of life (HRQoL) of long term prostate cancer patients who received leuprorelin acetate in microcapsules (LAM) for androgen-deprivation therapy (ADT). METHODS: The observational study was carried out by 30 office-based German urologists in 536 prostate cancer (PCa) patients treated for >=5 years with LAM and in 116 patients of an age-matched control group (CG). Data on HRQoL and health status was collected prospectively using validated questionnaires QLQ-C30, QLQ-PR25 and Karnofsky Index. Data on effectiveness (clinical response, prostate specific antigen [PSA], testosterone) and safety was collected retrospectively from patients' health records. We used descriptive statistics to analyze the data. RESULTS: The mean treatment duration was 8.6 years (range 4.5-19.8 years). General health status (QLQ-C30) was comparable for both groups. Differences were observed regarding physical - and role functioning. ADT patients rated single items slightly worse than CG. Karnofsky-Index showed comparable high values (median of 90%). QLQ-PR25 revealed more PCa-related symptoms for ADT patients. Within 6 months, median PSA level declined >90% and median testosterone levels declined below castration level from 4.0 to 0.2 ng/mL. Clinical response (European Organisation for Research and Treatment of Cancer criteria) was observed in at least 90% of ADT patients. CONCLUSIONS: Long-term ADT with LAM is a well-accepted, tolerated, effective, and low-burden treatment option for patients with advanced, hormone-sensitive PCa. PMID- 29183007 TI - MiR-193a-3p is an Important Tumour Suppressor in Lung Cancer and Directly Targets KRAS. AB - BACKGROUND/AIMS: MicroRNAs (miRNAs) have emerged as major regulators of tumour development and progression in non-small cell lung cancer (NSCLC). However, the role of miR-193a-3p in NSCLC is still unclear. METHODS: Quantitative RT-PCR was used to detect miR-193a-3p expression levels in NSCLC tumour tissues. CCK8, EdU and cell migration assays were performed to analyse the biological functions of miR-193a-3p in NSCLC cells. Luciferase reporter assays were used to validate the bioinformatics-predicted target genes of miR-193a-3p. Western blotting and RNA/DNA interference carried out to evaluate the association between miR-193a-3p and KRAS. RESULTS: miR-193a-3p expression was decreased in the NSCLC tumour tissues. We investigated the biological effects of miR-193a-3p both in vivo and in vitro and found that enforced expression of miR-193a-3p inhibited tumour formation and suppressed cell proliferation and cell migration. KRAS was found to be a potential target of miR-193a-3p, and dual luciferase reporter assays showed that miR-193a-3p directly binds to the 3'-untranslated region (3'-UTR) of KRAS mRNA. In addition, we found that changing the expression of KRAS had the opposite results to those induced by miR-193a-3p in the NSCLC cells. Importantly, simultaneous overexpression of miR-193a-3p and KRAS could counteract the effects of both on cellular functions. CONCLUSION: These findings highlight an important role for miR-193a-3p as a tumour suppressor in NSCLC pathogenesis via the regulation of KRAS expression. PMID- 29183008 TI - Correlates of Pulmonary Function in Children with Sickle Cell Disease and Elevated Fetal Hemoglobin. AB - OBJECTIVE: The current study was carried out to compare pulmonary function tests (PFTs) in pediatric Kuwaiti sickle cell disease (SCD) patients to age-matched normal controls and to investigate the association of PFTs with selected clinical and laboratory parameters. Subjects andMethods: There were 38 patients with SCD and 36 controls in the study. The patients were recruited from the Pediatric Hematology Clinics of Mubarak Al-Kabeer and Al-Amiri Hospitals, Kuwait, and were studied in steady state. The controls were healthy, non-sickle cell siblings of the patients. Forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), total lung capacity, and other PFT parameters were obtained using a constant-volume, variable-pressure, body plethysmograph. Hemoglobin, fetal hemoglobin, serum bilirubin, and lactate dehydrogenase were determined using standard methods. RESULTS: The mean ages of the patients and controls were 10.5 +/- 3.2 and 10.5 +/- 3.5 years, respectively. The FEV1% predicted of 84.1 +/- 15.4% among the patients was significantly lower than the 92.1 +/- 11.8% in the controls (p = 0.003). The FVC% predicted was also significantly lower (p = 0.022) in the patients than in the controls, although the values were generally within the normal range. There was no association of FEV1 with pain phenotype, acute chest syndrome (ACS), or blood transfusions. Also, there was no significant correlation with reticulocytes, bilirubin, or lactate dehydrogenase. CONCLUSIONS: In this study, changes in PFT, especially FEV1, developed early in the SCD patients. There was no demonstrable association with frequent vaso-occlusive crisis, ACS, and other variables. Hence, there is a need for follow-up studies with serial PFTs to identify vulnerable patients, who might need intervention to prevent early mortality. PMID- 29183009 TI - Hypoxia-Induced Mesenchymal Stromal Cells Exhibit an Enhanced Therapeutic Effect on Radiation-Induced Lung Injury in Mice due to an Increased Proliferation Potential and Enhanced Antioxidant Ability. AB - BACKGROUND/AIMS: Radiation therapy is an important treatment for thoracic cancer; however, side effects accompanied with radiotherapy lead to limited tumor control and a decline in patient quality of life. Among these side effects, radiation induced lung injury (RILI) is the most serious and common. Hence, an effective remedy for RILI is needed. Mesenchymal stromal cells (MSCs) are multipotent adult stem cells that have been demonstrated to be an effective treatment in some disease caused by tissue damage. However, unlike other injuries, RILI received limited therapeutic effects from implanted MSCs due to local hypoxia and extensive reactive oxygen species (ROS) in irradiated lungs. Since the poor survival of MSCs is primarily due to hypoxia and ROS generation, we hypothesize that persistent and adaptive hypoxia treatment induces enhanced resistance to hypoxic stress in implanted MSC. The aim of this study is to investigate whether persistent and adaptive hypoxia treatment of bmMSCs prior to their transplantation in injured mice enhanced survival and improved curative effects in RILI. METHODS: Primary bmMSCs were obtained from the marrow of six-week-old male C57BL6/J mice and were cultured either under normoxic conditions (21% O2) or hypoxic conditions (2.5% O2). Mice were injected with normoxia/hypoxia MSCs after thoracic irradiation (20 Gy). The therapeutic effects of MSCs on RILI were assessed by pathological examinations that included H&E staining, Masson staining and alpha-SMA staining; meanwhile, inflammatory factors were measured using an ELISA. The morphology of MSCs in vitro was recorded using a microscope and identified by flow cytometry, cell viability was measured using the CCK-8 assay, the potential for proliferation was detected by the EdU assay, and ROS levels were measured using a ROS fluorogenic probe. In addition, HIF-1alpha and several survival pathway proteins (Akt, p-Akt, Caspase-3) were also detected by western blotting. RESULTS: Implanted MSCs alleviated both early radiation-induced pneumonia and late pulmonary fibrosis. However, hypoxia MSCs displayed a more pronounced therapeutic effect compared to normoxia MSCs. Compared to normoxia MSCs, the hypoxia MSCs demonstrated greater cell viability, an enhanced proliferation potential, decreased ROS levels and increased resistance to hypoxia and ROS stress. In addition, hypoxia MSCs achieved higher activation levels of HIF-1alpha and Akt, and HIF-1alpha played a critical role in the development of resistance. CONCLUSION: Hypoxia enhances the therapeutic effect of mesenchymal stromal cells on radiation-induced lung injury by promoting MSC proliferation and improving their antioxidant ability, mediated by HIF-1alpha. PMID- 29183010 TI - Mild-to-Moderate Chronic Kidney Disease and Geriatric Outcomes: Analysis of Cross Sectional Data from the Berlin Aging Study II. AB - BACKGROUND: Mild-to-moderate chronic kidney disease (CKD G3a) is prevalent in older adults. Substantial evidence suggests that individuals with advanced CKD face a high risk for common geriatric conditions, like functional impairment and cognitive decline, whereas the relationships between mild-to-moderate CKD and functional impairment and cognitive decline, but also poor nutritional status and mood disorders, are still unclear. OBJECTIVE: The aim of this study was to explore associations between mild-to-moderate CKD and impairments in the core domains of geriatric assessment (GA) in a large cohort of community-dwelling older adults. METHODS: This was a cross-sectional analysis of 1,476 participants of the Berlin Aging Study II. Study participants were stratified as to presence or absence of CKD G3a (estimated glomerular filtration rate [eGFR] 45-59 mL/min/1.73 m2 vs. eGFR >=60 mL/min/1.73 m2). GA comprised the following instruments: the Activities of Daily Living Scale (ADL), the Timed up and Go (TUG), the Tinetti test (Tinetti), the Mini-Mental-State Examination (MMSE), the Geriatric Depression Scale (GDS), and the Mini Nutritional Assessment (MNA). We used logistic regression models to estimate multivariable-adjusted associations between CKD G3a and impairments in the respective domains. RESULTS: A total of 282 subjects with mild-to-moderate CKD (CKD G3a) were identified (19.1%). Overall, the prevalence of impairments identified was higher among subjects with compared to without CKD G3a (21 vs. 15.9%, p = 0.043). In multivariable-adjusted models, CKD G3a was consistently associated with increased odds of an impaired gait performance as to the TUG (adjusted odds ratio 2.06, 95% CI 1.04-4.09). In contrast, on average, individuals with and without CKD G3a did not differ as to their results in the MMSE, the ADL, the MNA, and the GDS. CONCLUSION: GA identified impairments in 21 versus 15.9% of older adults with and without mild to-moderate CKD, respectively. However, except for an increased likelihood of impaired gait performance (TUG) with mild-to-moderate CKD, we did not find independent associations between mild-to-moderate CKD and geriatric conditions. PMID- 29183011 TI - Transoral Robotic Surgery with Sialendoscopy for a Plunging Ranula. AB - BACKGROUND/AIMS: Plunging ranulas are oral mucoceles that often cannot be visualized directly and thus can be challenging to diagnose and differentiate from other neck lesions. Surgery is the preferred treatment option, but the optimal approach requires careful consideration. METHODS: We report the case of a plunging ranula presenting as an isolated neck mass in a 33-year-old patient. This patient was treated with a novel transoral robotic surgery (TORS)-assisted approach aided by sialendoscopy. RESULTS: TORS allowed for exceptional visualization and access to the plunging ranula and sublingual gland while avoiding critical neurovascular structures. The patient healed well without recurrence or complications. CONCLUSION: The TORS approach with sialendoscopy for plunging ranulas described in this case report shows promise and should be considered for certain clinical presentations. Additional studies evaluating the effectiveness of TORS for plunging ranulas may be indicated. PMID- 29183012 TI - Differential Expression of the Aryl Hydrocarbon Receptor and Transforming Growth Factor Beta 1 in Chronic Rhinosinusitis with Nasal Polyps with Allergic Rhinitis. AB - OBJECTIVE: This study aimed to determine the aryl hydrocarbon receptor (AhR) and transforming growth factor beta 1 (TGF-beta1) expression levels in chronic rhinosinusitis (CRS) and their possible correlation with allergic state and tissue remodeling. METHODS: Patients were enrolled and divided into the following groups: CRS without nasal polyps (NP) without allergic rhinitis (AR) (CRSsNPsAR; n = 20), CRS with NP with AR (CRSwNPwAR; n = 20), CRS with NP without AR (CRSwNPsAR; n = 20), and controls (n = 15). Tissue samples were analyzed by Masson trichrome staining for collagen, while the location and expression of AhR and TGF-beta1 were analyzed by immunohistochemistry, quantitative reverse transcription polymerase chain reaction (qRT-PCR), and Western blotting. RESULTS: The collagen amounts as well as AhR and TGF-beta1 mRNA and protein expression levels were significantly increased in the CRSsNPsAR group compared with the CRSwNP (CRSwNPsAR and CRSwNPwAR) samples (p < 0.01). However, higher collagen amounts (p < 0.05) and higher TGF-beta1 (p < 0.05) but lower AhR expression levels (p < 0.05) were detected in the CRSwNPwAR versus the CRSwNPsAR patients. Both AhR and TGF-beta1 expression were positively correlated with the collagen level in CRS samples (p < 0.01). CONCLUSIONS: Elevated AhR expression may be involved in the progression of tissue remodeling in CRSsNPsAR similar to TGF beta1 expression. Conversely, lower AhR expression may be involved in allergic reactions in CRSwNPwAR. PMID- 29183013 TI - Uremic Pruritus: An Itch with Ominous Consequences. PMID- 29183014 TI - Mechanosensitivity of Embryonic Neurites Promotes Their Directional Extension and Schwann Cells Progenitors Migration. AB - BACKGROUND/AIMS: Migration of Schwann cells (SCs) progenitors and neurite outgrowth from embryonic dorsal root ganglions (DRGs) are two central events during the development of the peripheral nervous system (PNS). How these two enthralling events preceding myelination are promoted is of great relevance from basic research and clinical aspects alike. Recent evidence demonstrates that biophysical cues (extracellular matrix stiffness) and biochemical signaling act in concert to regulate PNS myelination. Microenvironment stiffness of SCs progenitors and embryonic neurites dynamically changes during development. METHODS: DRG explants were isolated from day 12.5 to 13.5 mice embryos and plated on laminin-coated substrates with varied stiffness values. After 4 days in culture and immunostaining with specific markers, neurite outgrowth pattern, SCs progenitors migration, and growth cone shape and advance were analyzed with confocal fluorescence microscopy. RESULTS: We found out that growing substrate stiffness promotes directional neurite outgrowth, SCs progenitors migration, growth cone advance and presumably axons fasciculation. CONCLUSIONS: DRG explants are in vitro models for the research of PNS development, myelination and regeneration. Consequently, we conclude the following: Our observations point out the importance of mechanosensitivity for the PNS. At the same time, they prompt the investigation of the important yet unclear links between PNS biomechanics and inherited neuropathies with myelination disorders such as Charcot-Marie-Tooth 1A and hereditary neuropathy with liability to pressure palsies. Finally, they encourage the consideration of mechanosensitivity in bioengineering of scaffolds to aid nerve regeneration after injury. PMID- 29183016 TI - Meetings and Conferences.

PMID- 29183018 TI - Cytogenetic Characterization of a Population of Acanthodactylus lineomaculatus Dumeril and Bibron, 1839 (Reptilia, Lacertidae), from Southwestern Morocco and Insights into Sex Chromosome Evolution. AB - Acanthodactylus lineomaculatus is now regarded as an ecotype of A. erythrurus with which it has been recently synonymized. Despite the wide range of A. erythrurus, karyological data for this species are scarce and limited to classical cytogenetic studies carried out in individuals from only 2 locations (central Spain and Spanish enclave of Melilla on the northwestern Mediterranean Moroccan coast). Here, for the first time, we cytogenetically characterized individuals of A. lineomaculatus from the southwestern Moroccan Atlantic coast with the aim to increase the karyological knowledge of this wide-ranging species and to assess if any chromosomal changes can be found in this ecotype in comparison to other populations of this species. The diploid number of the individuals investigated is 2n = 38 which is typical of most lacertids. Active NORs were located telomerically in a medium-small pair of chromosomes, and no inactive NORs were detected. C-banding revealed an intensely heterochromatic W chromosome composed of AT-rich (centromere and long arm telomeric region) and GC rich (most of the long arm) regions, with extended interstitial telomeric sequences. These telomere-like repeats occupy the GC-rich heterochromatin of the W. The DNA composition of the W represents a trait distinguishing A. lineomaculatus (southwestern Morocco) from A. erythrurus from Spain that possess a DAPI-positive (AT-rich) W chromosome. In conclusion, these results add further evidence to the remarkable karyotype conservation in lacertid lizards, although differences in NOR location and in W chromosome structure among populations could suggest an incipient speciation mediated by chromosome changes in this wide ranging lizard species. PMID- 29183020 TI - Clinical Application of Quantitative Foetal Fibronectin for the Prediction of Preterm Birth in Symptomatic Women. AB - AIM: To evaluate the clinical application of the new Hologic quantitative foetal fibronectin (qfFN) bedside test for the prediction of spontaneous preterm birth (sPTB) in patients with symptoms suggestive of spontaneous threatened preterm labour (sPTL). METHODS: A prospective observational study with 154 pregnant women presenting signs and symptoms of sPTL was conducted. These women were subjected to a qfFN test between 22 and 35 weeks of gestation For each cut-off threshold, the ability to predict sPTB at within 14 days of conducting the test and <37 weeks was assessed by calculating the positive predictive value (PPV), negative predictive value (NPV), likelihood ratios, odds ratios, sensitivity, and specificity. RESULTS: For the outcome of delivery within 14 days of the test, qfFN <10 ng/mL had a 100% NPV and >200 ng/mL produced a 50.0% PPV; thus, qfFN added enhanced discrimination between high- and low-risk patients. The overall rate of sPTB (<37) was 13.3% (16/120), which increased progressively with increasing levels of fFN, with rates of 9.8% (8/81), 11.5% (3/26), 14.2% (1/7), 50% (3/6) within the 4 categories (fFN 0-9, 10-49, 50-200, 200+) respectively. CONCLUSIONS: The use of the qfFN testing in symptomatic patients allowed for more accurate identification of women at risk of sPTB and thus more directed management. PMID- 29183021 TI - Digital Applications in Cytopathology: Problems, Rationalizations, and Alternative Approaches. AB - OBJECTIVE: The aim of this work was to raise awareness of problems using digital applications for examining, teaching, and applying telecytology at King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia; University of Nebraska Medical Center (UNMC), Omaha, NE, USA; and University of Pittsburgh Medical Center (UPMC), Pittsburgh, PA, USA. The objective was to rationalize problems and propose alternative digital approaches. STUDY DESIGN: We sought to identify solutions to improve the following: (a) interpretive examination scores at KAMC for complex cytological templates (i.e., high-grade squamous intraepithelial lesions [HSIL]) when using static digital images (SDI) of cells in regions of interest (ROI); (b) visualization of cells in 3D clusters when teaching at UNMC using 2D and 3D whole slide imaging (WSI); and (c) visualization of cells through streaming telecytology at UPMC. RESULTS: Composite SDI (CSDI) improved test scores for complex interpretations (i.e., HSIL) by converging diagnostic criteria from multiple ROI. Multiplane focusing through z-stacked WSI facilitated the teaching of cytological entities characterized by 3D cell clusters and consultative telecytology through robotic cell analysis. CONCLUSIONS: Adequately visualized cytomorphology and multiplane focusing are essential for virtual cytopathology examinations, teaching, or consultative telecytology. Visualization of diagnostic criteria through 2D or 3D imaging is critical. Panoptiq panoramic WSI with integrated z-stacked video clips enables optimal applied telecytology. PMID- 29183022 TI - Rehabilitation of Cancer Survivors with Long-Term Toxicities. AB - The prognosis of cancer patients is constantly improving, which increases the importance of securing long-term quality of life. While therapy of treatment related disability mostly succeeds a cancer-specific treatment, physicians' awareness of simultaneous supportive therapy is rising. Early interventions such as physical exercise during chemotherapy are effective in reducing conditions such as fatigue. Specific sensorimotor training is able to improve or even prevent impairment of balance caused by neurotoxic agents. Although targeted therapies reduce the risk of side effects, combinations with established drugs have to be monitored with regard to cardiotoxicity, which is already a concern in children's cancer therapy and is now also focused on in long-term adult survivors. Improvement in diagnosis und surgical procedures have reduced impairments such as lymphedema. Furthermore, management and quality of life of breast cancer patients benefit from evidence showing that physical exercise and resistance training do not increase the risk of developing lymphedema.

PMID- 29183023 TI - The Recovery of Microvascular Status Evaluated by Optical Coherence Tomography Angiography in Patients after Successful Macular Hole Surgery. AB - PURPOSE: The aim of this study was to evaluate the optical coherence tomography angiography (OCTA) features of patients who underwent successful macular hole (MH) surgery. METHODS: Nineteen patients who underwent surgery in a single eye due to MH and 13 healthy subjects as a control group were included in the study. Vascular densities, flow indexes, and the foveal avascular zone (FAZ) area in superficial and deep retinal capillary plexuses were evaluated by OCTA in the right eyes of the control group, and both the surgical and healthy fellow eyes of the patients. RESULTS: The mean vascular densities of the superficial and deep capillary plexuses were significantly lower in the surgical eyes than in the control group (44.1 vs. 49.6%, p = 0.002, and 47.3 vs. 59.1%, p = 0.009, respectively). The mean superficial and deep capillary flow indexes were significantly lower in the surgical eyes than in the control group (0.85 vs. 1.35, p = 0.003, and 0.57 vs. 1.45, p = 0.001, respectively), while the mean superficial and deep FAZ area were significantly greater in the surgical eyes in comparison to the control group (0.55 vs. 0.32, p < 0.001, and 0.64 vs. 0.37, p = 0.001, respectively). There was no difference between the flow indexes of both layers of the healthy fellow eyes and the control group. CONCLUSIONS: These preliminary results may be an explanation for unsatisfactory visual gain after surgery, despite the successful anatomical closure of the MH.

Lymph node dissection is recommended for tumours with nodal involvement, and is rarely performed in the absence of adenopathy. We report a series of patients with squamous cell carcinomas and evaluate the rate of lymph node invasion and its impact on survival. This is a retrospective study of 72 patients treated for squamous cell carcinoma of the hard palate and maxillary alveolar ridge between January 1, 1998 and December 31, 2008 in two cancer centres. Using clinical and radiological assessment, tumours were classified as T1-T2 in 25 patients (34.7%) and T3-T4 in 47 patients (65.3%). At diagnosis, 16 (22.2%) patients had clinical and/or radiological nodal involvement and 7 patients (9.7%) distal metastasis. Among N0 patients, 13 (18%) experienced isolated lymph node recurrence. Two-year global survival was 60%; 5-year survival was 34%. The rate of lymph node invasion observed in squamous cell carcinoma of the hard palate and maxillary alveolar ridge does not differ from other oral cavity sites. Because nodal recurrence worsens the prognosis of such a patient, lymph node dissection should be considered at an early stage, even among N0 patients. PMID- 29183026 TI - Late Effects and Long-Term Follow-Up after Cancer in Childhood. AB - Today, 80% of children and adolescents with cancer survive their disease. From the results of aftercare research arises the question: Are the survivors also healthy? Many late effects depend on the type of cancer and its treatment. Patients with brain tumors and with malignant sarcomas are very often affected by secondary diseases. Data from the USA report that around 2/3 of all patients still living 30 years after their cancer treatment in childhood suffer from late complications. Equivalent figures for Germany were previously unavailable. In accordance with the guidelines, regular follow-ups to diagnose a relapse or possible late effects have mostly been carried out in the primary children's hospitals. In adolescence and in young adulthood, this regimen does no longer serve the patients' mental and physical needs. To ensure appropriate care for this maturing patient group, interdisciplinary approaches (e.g., aftercare consultations) are required in which pediatric oncologists collaborate with colleagues from the field of internal medicine and other disciplines. Individual, risk-adapted (depending on the cancer treatment) aftercare plans based on pre existing aftercare recommendations must be drawn up for every patient and to secure the early diagnosis of possible late effects. The conservation of health and quality of life after cancer treatment (in all age groups) will in the future not only represent a social but also an economic consideration. PMID- 29183027 TI - Identification of Subpathway Signatures For Ovarian Cancer Prognosis by Integrated Analyses of High-Throughput miRNA and mRNA Expression. AB - BACKGROUND/AIMS: Ovarian cancer (OC) causes more death and serious conditions than any other female reproductive cancers, and many expression signatures have been identified for OC prognoses. However, no significant overlap is found among signatures from different studies, indicating the necessity of signature identifications at the functional level. METHODS: We performed an integrated analyses of miRNA and gene expressions to identify OC prognostic subpathways (pathway regions). Using The Cancer Genome Atlas data set, we identified core prognostic subpathways, and calculated subpathway risk scores using both miRNA and gene components. Finally, we performed global risk impact analyses to optimize core subpathways using the random walk algorithm. RESULTS: Subpathway level analyses displayed more robust results than the gene- and miRNA-level analyses. Moreover, we verified the advantage of core subpathways over the entire pathway-based results and their prognostic performance in two independent validation data sets. Based on the global impact score, 13 subpathway signatures were selected and a combined subpathway-based risk score was further calculated for OC patient prognoses. CONCLUSIONS: Overall, it was possible to systematically perform integrated analyses of the expression levels of miRNAs and genes to identify prognostic subpathways and infer subpathway risk scores for use in OC clinical applications. PMID- 29183028 TI - Radiofrequency Ablation of Atrial Fibrillation in Patients with Ebstein's Anomaly: A Two-Case Report. AB - Ebstein's anomaly (EA) is a rare congenital heart disease characterized by "atrialization" of the right ventricle, due to apical displacement of the tricuspid leaflets into the right ventricle. Patients with EA may develop all kinds of supraventricular arrhythmias requiring radiofrequency ablation. Atrial fibrillation (Afib) is a common arrhythmia in EA patients, and results in debilitating symptoms that often require surgical treatment. This is a follow-up report of 2 patients with EA undergoing radiofrequency ablation for Afib. The first patient underwent pulmonary vein isolation (PVI) and the ablation of a concomitant atrioventricular nodal reentrant tachycardia. The second patient was also treated with a PVI and a redo PVI 8 months later. Both patients remain in sinus rhythm 8 months on. Radiofrequency ablation is the therapy of choice for patients with pharmacological refractory Afib, but it is not common in patients with EA. PMID- 29183029 TI - Successful Evidence-Based Treatment of Patients with Advanced Pancreatic Cancer in Community-Based Oncology Group Practices. AB - BACKGROUND: Randomized clinical trials do not reflect the day-to-day reality of patient care; hence, the treatment of patients with advanced pancreatic cancer in oncology group practices was evaluated. PATIENTS AND METHODS: All consecutive patients with advanced pancreatic cancer who were treated between 01/2012 and 12/2015 in 4 oncology group practices were analyzed retrospectively using SPSS software. RESULTS: 324 patients with a median age of 70 years (range 32-94 years) were analyzed. The majority were male (56%) and had distant metastases (74%). Chemotherapy was the major modality of treatment (86%) with a median overall survival (OS) of 33.3 weeks (range 1.7-245.4 weeks). Chemotherapy significantly (p < 0.001) improved OS in comparison to best supportive care only (37.6 vs. 13.9 weeks). Patients with locally advanced disease had a better prognosis compared to patients with metastases (median OS 49.6 vs. 30.4 weeks; p < 0.001). An age adjusted Charlson comorbidity score of >= 9 was found to influence the OS significantly (p = 0.004). CONCLUSION: Chemotherapy remains the main modality of treatment for patients with advanced pancreatic cancer with an OS comparable to prospective randomized trials. The OS of this patient cohort has remained the same over the last 20 years despite advances in treatment modalities. PMID- 29183030 TI - Emodin Inhibits ATP-Induced Proliferation and Migration by Suppressing P2Y Receptors in Human Lung Adenocarcinoma Cells. AB - BACKGROUND/AIMS: Extracellular ATP performs multiple important functions via activation of P2 receptors on the cell surface. P2Y receptors play critical roles in ATP evoked response in human lung adenocarcinoma cells (A549 cells). Emodin is an anthraquinone derivative originally isolated from Chinese rhubarb, possesses anticancer properties. In this study we examined the inhibiting effects of emodin on proliferation, migration and epithelial-mesenchymal transition (EMT) by suppressing P2Y receptors-dependent Ca2+ increase and nuclear factor-kappaB (NF KB) signaling in A549 cells. METHODS: A549 cells were pretreated with emodin before stimulation with ATP for the indicated time. Then, intracellular Ca2+ concentration ([Ca2+]i) was measured by Fluo-8/AM staining. Cell proliferation and cell cycle progression were tested by CCK8 assay and flow cytometry In addition, wound healing and western blot were performed to determine cell migration and related protein levels (Bcl-2, Bax, claudin-1, NF-kappaB). RESULTS: Emodin blunted ATP/UTP-induced increase of [Ca2+]i and cell proliferation concentration-dependently Meanwhile, it decreased ATP-induced cells accumulation in the S phase. Furthermore, emodin altered protein abundance of Bcl-2, Bax and claudin-1 and attenuated EMT caused by ATP. Such ATP-induced cellular reactions were also inhibited by a nonselective P2Y receptors antagonist, suramin, in a similar way to emodin. Besides, emodin could inhibit activation of NF-kappaB, thus suppressed ATP-induced proliferation, migration and EMT. CONCLUSION: Our results demonstrated that emodin inhibits ATP-induced proliferation, migration, EMT by suppressing P2Y receptors-mediated [Ca2+]i increase and NF-kappaB signaling in A549 cells. PMID- 29183031 TI - Novel PCR Assays for the Detection of Biological Agents Responsible for Wheat Rust Diseases: Puccinia triticina and Puccinia striiformis f. sp. tritici. AB - The species Puccinia triticina (Pt) and Puccinia striiformis f. sp. tritici (Pst) are devastating cereal pathogens that cause leaf and stripe rust diseases. We developed PCR assays for the species-specific detection of Pt and Pst, 2 biological agents that cause wheat rust disease. For each pathogen, we validated 3 primer sets that target the second largest subunits of the RNA polymerase II (rpb2) and beta-tubulin 1 (tub1) genes. The specificities of the primers were verified using naturally infected plant materials with visual symptoms of disease. All primer sets amplified a single DNA fragment of the expected length. The primer sets LidPr15/16, LidPr1/2, and LidPs13/14 were able to detect small amounts of pure fungal DNA with sensitivities of 0.1, 1, and 10 pg/MUL, respectively. A sufficient detection limit (1 pg/MUL to 5 ng/MUL) was observed for all assays when the sensitivity test was performed with host plant DNA. The study also evaluated the simultaneous detection of both rust pathogens, and the multiplex PCR assay generated amplicons of 240 and 144 bp in length for Pts (LidPs9/10) and Pt (LidPr1/2), respectively. PMID- 29183032 TI - Return to Work of Cancer Survivors. AB - Due to improving treatment options, the number of so-called long-term cancer survivors is steadily increasing. Current studies assume that more than 60% of adults survive their cancer. These patients have a variety of problems (chemotherapy-induced neuropathy, fatigue, etc.) that require very special care. In addition to somatic and psychological side effects of the cancer or its treatment, these patients also suffer from the financial and social consequences of the disease. Thus, for a long-term survivor of working age, the question of a 'return to work' represents a significant problem since otherwise the financial existence of the patient, and often the family, may substantially deteriorate. Studies show that cancer patients classify financial worries with regard to the quality of life as more significant than physical or psychological side effects of the cancer or its treatment. Furthermore, there are initial studies showing that the social descent due to the disease may also prove relevant for cancer prognosis. In contrast, it was shown in studies and in a Cochrane analysis that professional assistance and support services are suitable for keeping patients in their professional lives. Therefore, both patients and physicians need to be aware of this problem. PMID- 29183033 TI - The Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-Fatigue Subscale): Validity and Reliability of the Iranian Version. AB - BACKGROUND: The aim of this study was to translate and validate the Functional Assessment of Chronic illnesses Therapy-Fatigue (FACIT-fatigue subscale) in Iran. METHODS: The Persian version of the FACIT-fatigue scale was developed using the forward-backward translation method. The questionnaire was then presented to a consecutive sample of breast cancer patients (n = 208) attending the Iranian Center of Breast Cancer (ICBC). The reliability was assessed by internal consistency and test-retest using Cronbach's alpha and intraclass correlation coefficient (ICC), respectively. Convergent validity was examined by correlation between the FACIT-fatigue scale and the Hospital and Depression Scale (HADS). In addition, discriminant validity was evaluated by the ability of the scale to differentiate between patients who differed in disease stage. RESULTS: The internal consistency of the questionnaire was excellent (Cronbach's alpha = 0.92). The ICC for the FACIT-fatigue was 0.84. Strong correlations were observed between FACIT-fatigue and depression (r = -0.69) and anxiety (r = -0.72) scores. The FACIT-fatigue discriminated well between subgroups of patients who differed in stage (p < 0.001) and probable caseness of anxiety and depression disease (p < 0.001). CONCLUSION: The Iranian version of the FACIT-fatigue subscale is a valid and reliable instrument to measure fatigue in cancer patients. PMID- 29183034 TI - Adjuvant Radiotherapy in High-Risk Squamous Cell Carcinoma of the Vulva: A Two Institutional Italian Experience. AB - BACKGROUND: The aim of this study was to assess the treatment benefit and patterns of recurrence for patients with high-risk vulvar squamous cell carcinoma treated with surgery followed by adjuvant radiotherapy (RT). PATIENTS AND METHODS: From January 1999 to June 2016, 51 patients underwent total or partial deep vulvectomy with inguinofemoral lymphadenectomy followed by adjuvant RT with 45-50 Gy in 25 fractions +/- a 4-10 Gy boost. 17 (33.3%) women received concomitant chemotherapy. RESULTS: Median overall survival was 81 months. The 5 year disease-free survival and overall survival rates were 52 and 63%, respectively. In univariate and multivariate analysis, patients aged <= 76 years and those receiving an RT total dose of > 54 Gy had a significantly lower risk of progression (p = 0.044 and 0.045; p = 0.012 and 0.018, respectively) and death (p = 0.015 and 0.011; p = 0.015 and 0.026, respectively). There was a trend towards a lower risk of progression for patients with tumor size <= 4 (p = 0.098) and negative lymphovascular space involvement (p = 0.080). Also, there was a trend towards a higher risk of death (p = 0.075) for grade 3 tumors. Concomitant chemotherapy provided no significant benefit. CONCLUSION: Only age and RT total dose are significant prognostic variables for squamous cell carcinoma of the vulva treated with primary surgery and adjuvant RT to improve local and locoregional control. PMID- 29183035 TI - User-Oriented Evaluation of a Robotic Rollator That Provides Navigation Assistance in Frail Older Adults with and without Cognitive Impairment. AB - BACKGROUND: Navigational skills decline with age, and this decline is even more pronounced in cognitively impaired (CI) older adults. Navigation assistance is an emerging functionality of robotic rollators (RRs). The evidence on the effectiveness of RR-integrated navigation systems in potential end-users is, however, scarce. OBJECTIVE: To determine whether RR-provided navigation assistance improves navigation within a real-life environment in the intended user group of frail older adults with and without cognitive impairment currently using a rollator in daily life. METHODS: A randomized, between-subject, 2 * 2 factorial design was conducted to test the effects of navigation assistance and cognitive status on participants' navigation performance. Twenty CI (Mini-Mental State Examination [MMSE] 17-26) and 22 not cognitively impaired (NCI; MMSE >26) older rollator users (age 82.5 +/- 8.7 years) were included. Participants were matched for cognitive status (CI vs. NCI) and randomized to one of two conditions: RR (1) with or (2) without activated navigation system. All participants had to complete a two-section navigation path with the RR in an unfamiliar, real-life environment. Participants with RR-assisted navigation were supported in wayfinding by directional audio cues of the RR-integrated navigation system. Participants without RR-assisted navigation had to complete the sections by orienting themselves along conventional signposts. Outcomes were success rate, completion and stopping time, number of stops, walking distance, and gait speed. RESULTS: The navigation assistance condition had no significant effect on the success rate in the CI, NCI, or total group. We found significant interactions between navigation assistance and cognitive status for both sections (p = 0.002 0.040), such that RR-assisted navigation reduced the completion time (both sections), stopping time (section 1), and number of stops (section 2) in the CI (p <= 0.001-0.014) but not in the NCI group. On the more complex section 2, RR assisted navigation led to a reduced stopping time and walking distance in the total group (p = 0.014-0.016). CONCLUSION: The RR-integrated navigation system was effective for improving navigation within a real-life environment in potential end-users, especially in those with cognitive impairment. This is the first study to provide statistical evidence on the effectiveness of an RR integrated navigation system in the intended user group. PMID- 29183037 TI - Efficacy of a New Post-Mouthwash Intervention (Wiping Plus Oral Nutritional Supplements) for Preventing Aspiration Pneumonia in Elderly People: A Multicenter, Randomized, Comparative Trial. AB - BACKGROUND/AIMS: Aspiration pneumonia is a common cause of death among the elderly (>=90-year-old) in nursing homes. Studies suggest that its incidence could be reduced by oral care interventions. We aimed to evaluate the efficacy of a new oral care intervention: wiping plus oral nutritional supplements (ONS). METHODS: This prospective observational study was conducted in 252 patients (age 88.0 +/- 6.5 years) in 75 nursing homes, rehabilitation hospitals, and other care facilities. Patients were randomly divided into an intervention group (n = 74) and a control group (n = 107), whose members received conventional oral care. Body mass index, activities of daily living (Barthel index), and complete blood count and biochemistry parameters were measured at 2, 4, 6, and 8 months. RESULTS: The cumulative incidence of pneumonia at 8 months tended to be lower in the intervention than in the control group (7.8 vs. 17.7%, p = 0.056) and was significantly lower for men in the intervention group (p = 0.046). CONCLUSIONS: Our new intervention "wiping plus providing ONS" method appears to help prevent aspiration pneumonia, thereby reducing mortality risk. In this study, we disseminate information on how this method is used in Japan. PMID- 29183036 TI - Surgical Approach to "Right Hepatic Core": Deepest Region Surrounded by Major Portal Pedicles and Right Hepatic Vein. AB - BACKGROUND/AIMS: The resection of hepatic tumors located in the region surrounded by the right hepatic vein (RHV) and the portal pedicles of the right paramedian/lateral sector (the right hepatic core) remains a challenge for liver surgeons. The aim of this study was to demonstrate the surgical techniques and outcomes of our atypical-parenchyma-sparing hepatectomy (atypical-PSH) approach for the removal of tumors in the right hepatic core. METHODS: Perioperative records of 1,179 consecutive patients who had undergone hepatectomy for hepatocellular carcinoma or colorectal liver metastases from January 2006 to December 2014 were retrospectively reviewed. RESULTS: Twenty-six patients (2%) had a tumor in the right hepatic core. Among them, 20 patients underwent atypical PSH, including the anterior approach (resection of the right paramedian hepatic parenchyma, n = 9), posterior approach (resection of the right lateral hepatic parenchyma, n = 10), and transhepatic approach (tumor enucleation from the raw surfaces along the RHV, n = 1). Their postoperative outcomes were similar to the remaining 6 patients who had undergone right hepatectomy. CONCLUSIONS: Atypical PSH can be safely applied for the removal of tumors in the right hepatic core. This technique may have potential advantages in preserving hepatic function for postoperative chemotherapy and repeated hepatectomy for future recurrence. PMID- 29183039 TI - MiR-146a Aggravates LPS-Induced Inflammatory Injury by Targeting CXCR4 in the Articular Chondrocytes. AB - BACKGROUND/AIMS: Osteoarthritis (OA) as a degenerative disease is a major problem in ageing populations. To better understand the molecular mechanisms in the pathogenesis of OA, this study explored the role of microRNA (miR)-146a in the articular chondrocytes. METHODS: The articular chondrocyte line ATDC5 was used to simulate inflammatory injury by LPS administration in vitro. Cell viability, apoptosis, mRNA expressions and productions of inflammatory factors were assessed, respectively. Mir-146a and Cxcr4 mRNA expressions were measured by qRT PCR. Targeting effect of miR-146a on Cxcr4 3'UTR was assessed by luciferase activity analysis. Protein expression levels of CXCR4 and main factors in PI3K/AKT, Wnt/beta-catenin signal pathways were measured by western blotting. RESULTS: LPS exposure suppressed cell viability, prompted apoptosis of ATDC5 cells, and stimulated expression and release of inflammatory factors. MiR-146a was upregulated in LPS-induced cells. Overexpression of miR-146a further aggravated LPS-induced inflammatory injury, while it was reduced after miR-146a was knocked down. CXCR4 expression was negatively regulated by miR-146a. CXCR4 was a direct target of miR-146a and thus involved in regulatory effect of miR 146a on the injured chondrocytes, which was also related with phosphorylation levels of PI3K/AKT and expressions of Wnt/beta-catenin signal factors. CONCLUSION: miR-146a promoted inflammatory response of articular chondrocytes via targeting CXCR4 and suppressing CXCR4 expression. Overexpression of CXCR4 could attenuate the inflammatory injury. Our findings provided novel evidence which might be useful for further studies exploring therapeutic approaches for OA via targeting miR-146a. PMID- 29183040 TI - Oncological Rehabilitation. AB - An increasing number of patients are living with or surviving cancer due to improvements in detection and treatment. However, patients who survive cancer may experience functional disabilities that impact on health, quality of life and ability to work. For example, physical disorders may include fatigue, reduced muscle strength, cognitive dysfunction, paresthesia or nutrition problems, while mental symptoms may include anxiety, depression, fear of relapse or insomnia. Multidimensional oncological rehabilitation programs have been developed to address these disabilities and to help cancer patients and long-term survivors to reduce morbidity and to improve quality of life. There has been evidence showing that multidisciplinary oncological rehabilitation interventions involving physical, psycho-educational and vocational components led to a better quality of life and a higher rate of return to work than just usual care. In Germany, oncological rehabilitation is an integral part of the healthcare system and part of a modern cancer treatment that immediately follows operation, medical treatment or radiotherapy. Furthermore, it can be used if functional disabilities still remain years after cancer treatment. This review describes the German history and legal basis of oncological rehabilitation as well as the contents of and the evidence for this comprehensive and interdisciplinary treatment. PMID- 29183041 TI - Association Between Hyperreflective Dots on Spectral-Domain Optical Coherence Tomography in Macular Edema and Response to Treatment. AB - Purpose: To investigate the association between hyperreflective dots (HRDs) on spectral-domain optical coherence tomography (SD-OCT) and response to intravitreal bevacizumab (IVB) or dexamethasone injection in eyes with diabetic macular edema (DME) or macular edema due to retinal vein occlusion (RVO). Methods: A retrospective review was conducted involving patients with DME or macular edema due to RVO. Patients with treatment-naive macular edema were initially treated with three consecutive IVB injections and classified based on the treatment response to bevacizumab. After three consecutive IVB injections, bevacizumab nonresponders were treated using dexamethasone implants and reclassified based on the treatment response. The best-corrected visual acuity, number of HRDs, and outer plexiform layer (OPL) disruptions were analyzed according to the treatment response. Results: Eighty-two eyes with DME and 68 eyes with RVO were included in this study. Thirty-six (43.9%) eyes with DME and 22 (32.4%) eyes with RVO were bevacizumab nonresponders. The number of baseline HRDs in bevacizumab nonresponders (16.06 +/- 6.60 in DME, 14.23 +/- 4.09 in RVO) was significantly greater than that in responders (11.26 +/- 3.64, P < 0.001 in DME, 11.17 +/- 4.83, P = 0.013 in RVO), and it did not decrease after IVB injections. Unlike the response to bevacizumab, eyes that responded to dexamethasone implant but not to IVB had significantly more HRDs (19.56 +/- 6.75) than eyes that did not respond (11.50 +/- 3.78, P = 0.006). The OPL disruption rate was significantly higher in bevacizumab nonresponders than in responders (P < 0.001 in DME and P = 0.001 in RVO). Conclusions: In patients with DME or macular edema due to RVO, the number of HRDs on SD-OCT may be a predictive indicator of the response to IVB injection or dexamethasone implant. In bevacizumab responders, the number of HRDs on SD-OCT was small. In contrast, more HRDs, which might reflect increased inflammation in the retina, were observed in dexamethasone responders. Therefore, dexamethasone implants might be more effective in DME or RVO eyes with multiple HRDs and OPL disruption on SD-OCT. PMID- 29183042 TI - Expression and Regulation of S100 Fused-Type Protein Hornerin at the Ocular Surface and Lacrimal Apparatus. AB - Purpose: The S100 fused-type proteins hornerin (HRNR) and filaggrin-2 (FLG2) are members of the epidermal differentiation complex, which is involved in terminal differentiation of keratinocytes via cornification as well as maintenance of the epidermal antimicrobial barrier. We investigated the expression and possible regulation of HRNR and FLG2 at the ocular surface and in the lacrimal apparatus. Methods: Tissues of the lacrimal apparatus and ocular surface were analyzed systematically by means of RT-PCR, immunohistochemistry, and immuntransmission electron microscopy (iTEM) for their ability to express and produce HRNR and FLG2. In addition, inducibility and regulation of HRNR were studied in cultivated human corneal (HCE), conjunctival (HCjE), as well as meibomian gland (HMGEC) epithelial cell line by real-time RT-PCR. Results: RT-PCR, immunohistochemistry, and iTEM revealed constitutive expression of HRNR in the epithelium of cornea, conjunctiva, nasolacrimal ducts, and acinus cells of lacrimal and meibomian glands. HRNR also was detected in tears of healthy volunteers. No expression of FLG2 could be detected in tissue samples of the ocular surface and lacrimal apparatus. Real-time RT-PCR revealed a decreased HRNR gene expression after challenge with proinflammatory cytokines and supernatants of Escherichia coli and Pseudomonas aeroginosa in HCE cells, whereas HCjE cells revealed no changes. In HMGECs serum-induced differentiation and application of all-trans retinoic acid significantly increased HRNR gene expression. Conclusions: The data suggest that HRNR, but not FLG2, is a component of the ocular surface and lacrimal apparatus, including meibomian glands. HRNR seems to contribute to the maintenance of the epithelial barrier at the ocular surface and, thus, also may be involved in ocular surface diseases. PMID- 29183043 TI - Benzo(e)pyrene Inhibits Endothelium-Dependent NO-Mediated Dilation of Retinal Arterioles via Superoxide Production and Endoplasmic Reticulum Stress. AB - Purpose: To investigate whether benzo(e)pyrene (B(e)P), a toxicant in cigarette smoke, affects the endothelium-dependent nitric oxide (NO)-induced vasodilation of the retinal arterioles, and whether oxidative stress, distinct protein kinase signaling pathways, and endoplasmic reticulum (ER) stress are associated with the B(e)P-induced effect on the retinal arterioles. Methods: In this in vitro study, porcine retinal arterioles were isolated, cannulated, and pressurized without flow. These vessels were treated with intraluminal administration of B(e)P or B(e)P plus blockers for 180 minutes. Diametric changes to agonists were recorded by videomicroscopy. Results: Intraluminal treatment with 100 MUM B(e)P for 180 minutes significantly reduced the arteriolar vasodilation caused by the endothelium-dependent NO-mediated agonists bradykinin and A23187 but not that caused by endothelium-independent NO donor sodium nitroprusside. The adverse effects of B(e)P on the vasodilatory action of bradykinin were prevented by the superoxide scavenger 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPOL), the nicotinamide adenine dinucleotide phosphate-oxidase (NADPH oxidase) inhibitor apocynin, the c-Jun N-terminal kinase (JNK) inhibitor SP600125, the p38 mitogen activated protein kinase inhibitor SB203580, genistein, resveratrol (RSV), and the ER stress inhibitor 4-phenylbutyrate (4-PBA). The xanthine oxidase inhibitor allopurinol did not alter the effect of B(e)P on the vasodilatory action induced by bradykinin. Conclusions: B(e)P decreases the endothelium-dependent NO-induced vasodilation in the retinal arterioles through the production of superoxide from NADPH oxidase, which is linked to JNK and p38 kinase. The results suggested that ER stress is instrumental in B(e)P-induced endothelial dysfunction and that genistein and RSV might preserve endothelial function. PMID- 29183044 TI - Inflammatory and Neuronal Biomarkers Associated With Retinal Thinning in Pediatric HIV. AB - Purpose: The pathophysiology of neuroretinal thinning in children with human immunodeficiency virus (HIV) is poorly understood. The current study aimed to assess whether neuroretinal thinning in clinically stable perinatally HIV infected children was associated with biomarkers of immune activation, inflammation, and neuronal damage. Methods: Inflammation-associated and neuronal damage markers were measured in blood and cerebrospinal fluid (CSF) of HIV infected children aged 8 to 18 years. Using mixed-effects regression analyses, we assessed associations between these biomarkers and neuroretinal layer thickness, as measured with spectral-domain optical coherence tomography. Results: Thirty two HIV-infected children (median age 13.6 years, 50% male) were included. Blood plasma levels of interleukin-6, monocyte chemoattractant protein-1, and soluble intercellular adhesion molecule-1 were inversely correlated with foveal inner plexiform layer thickness (coef = -4.40, P < 0.001; coef = -9.67, P = 0.047; coef = -10.48, P = 0.042, respectively). Plasma interleukin-6 was inversely correlated with foveal ganglion cell layer thickness (coef = -2.49, P = 0.010). Total Tau levels in CSF were inversely correlated with outer nuclear layer and inner segments thickness (foveal: coef = -19.3, P = 0.029; pericentral: coef = -18.09, P = 0.006) and pericentral total retinal thickness (coef = -28.2, P = 0.017). Conclusions: Neuroretinal thinning was associated with inflammation-associated and neuronal injury biomarkers in a cohort of antiretroviral therapy-treated perinatally HIV-infected children. These findings suggest that ongoing immune activation, inflammation, and neuronal injury occur in parallel with retinal thinning in pediatric HIV. PMID- 29183045 TI - Peripapillary Microvascular Improvement and Lamina Cribrosa Depth Reduction After Trabeculectomy in Primary Open-Angle Glaucoma. AB - Purpose: To evaluate peripapillary microvascular changes in patients with primary open-angle glaucoma (POAG) after trabeculectomy using optical coherence tomography (OCT) angiography, and to determine the influence of lamina cribrosa (LC) displacement on changes in peripapillary microvasculature. Methods: The peripapillary retinal microvasculature and LC were imaged using OCT angiography and OCT-enhanced depth imaging, respectively. The microvasculature and LC depth (LCD) were measured before, and 1 week, 1 month, and 3 months after trabeculectomy. The microvascular improvement was arbitrarily defined as a reduction >30% of the area of vascular dropout (blue/black areas with <20% vessel density on the color-coded vessel density map). LCD was determined as the mean of vertical distance between the anterior LC surface and a reference plane of Bruch's membrane. Results: Thirty-one eyes of 31 POAG patients were included. At 3 months postoperatively, intraocular pressure (IOP) and LCD were significantly decreased from 26.3 +/- 11.8 mm Hg to 12.5 +/- 3.6 mm Hg, and 501.1 +/- 130.2 MUm to 455.8 +/- 112.7 MUm, respectively (all P < 0.001), compared with baseline. The microvascular improvement was observed in 19 eyes (61.3%) at 3 months after trabeculectomy. The maximal reductions in IOP and LCD were significantly greater in eyes with improved microvasculature compared to eyes without improvement (P = 0.020 and P = 0.005). The microvascular improvement was significantly associated with maximal reduction in LCD (odds ratio, 1.062; P = 0.026). Conclusions: Trabeculectomy can improve peripapillary retinal microcirculation in patients with POAG. This finding suggests that the reduction of LCD induced by lowering IOP may affect peripapillary microvascular improvement in eyes with POAG. PMID- 29183046 TI - In Vivo Analysis of Angle Dysgenesis in Primary Congenital, Juvenile, and Adult Onset Open Angle Glaucoma. AB - Purpose: The purpose of this study was to comparatively evaluate angle dysgenesis in vivo, among congenital, juvenile, and adult-onset open angle glaucoma patients. Methods: A cross-sectional evaluation of 96 glaucoma patients, 22 children with primary congenital glaucoma (PCG) old enough to cooperate for optical coherence tomography (OCT), 34 juvenile-onset open angle glaucoma (JOAG) patients, 40 adult-onset primary open angle glaucoma (POAG), and 30 healthy subjects, was carried out using high-resolution anterior segment spectral domain (SD)-OCT. Subgroup analysis was done for presence/ absence of angle dysgenesis as defined by presence of abnormal tissue/hyperreflective membrane within angle recess and/or absence of Schlemm's canal (SC). Results: Morphologic features suggestive of angle dysgenesis such as the presence of abnormal tissue at the angle and a hyperreflective membranous structure covering the meshwork were seen in all PCG eyes (100%), in 14 (40%) JOAG eyes, and none of the POAG eyes in comparison to healthy eyes (P = 0.01, P = 0.03, and P = 0.23 for PCG, JOAG, and POAG, respectively). SC could be seen in 27 (90%) healthy eyes compared with only 7 (30%) in PCG (P = 0.01) 20 (60%) JOAG eyes (P = 0.03), and 26 (65%) adult-onset POAG eyes (P = 0.23; chi2 test). Conclusions: Angle dysgenesis in the form of abnormal tissue at the angle/hyperreflective membrane and/or absence of SC could be identified on anterior segment SD-OCT, which can be used for in vivo evaluation of eyes with developmental glaucoma.

AB - Importance: Fecal microbiota transplantation (FMT) is effective in preventing recurrent Clostridium difficile infection (RCDI). However, it is not known whether clinical efficacy differs by route of delivery. Objective: To determine whether FMT by oral capsule is noninferior to colonoscopy delivery in efficacy. Design, Setting, and Participants: Noninferiority, unblinded, randomized trial conducted in 3 academic centers in Alberta, Canada. A total of 116 adult patients with RCDI were enrolled between October 2014 and September 2016, with follow-up to December 2016. The noninferiority margin was 15%. Interventions: Participants were randomly assigned to FMT by capsule or by colonoscopy at a 1:1 ratio. Main Outcomes and Measures: The primary outcome was the proportion of patients without RCDI 12 weeks after FMT. Secondary outcomes included (1) serious and minor adverse events, (2) changes in quality of life by the 36-Item Short Form Survey on a scale of 0 (worst possible quality of life) to 100 (best quality of life), and (3) patient perception on a scale of 1 (not at all unpleasant) to 10 (extremely unpleasant) and satisfaction on a scale of 1 (best) to 10 (worst). Results: Among 116 patients randomized (mean [SD] age, 58 [19] years; 79 women [68%]), 105 (91%) completed the trial, with 57 patients randomized to the capsule group and 59 to the colonoscopy group. In per-protocol analysis, prevention of RCDI after a single treatment was achieved in 96.2% in both the capsule group (51/53) and the colonoscopy group (50/52) (difference, 0%; 1-sided 95% CI, -6.1% to infinity; P < .001), meeting the criterion for noninferiority. One patient in each group died of underlying cardiopulmonary illness unrelated to FMT. Rates of minor adverse events were 5.4% for the capsule group vs 12.5% for the colonoscopy group. There was no significant between-group difference in improvement in quality of life. A significantly greater proportion of participants receiving capsules rated their experience as "not at all unpleasant" (66% vs 44%; difference, 22% [95% CI, 3%-40%]; P = .01). Conclusions and Relevance: Among adults with RCDI, FMT via oral capsules was not inferior to delivery by colonoscopy for preventing recurrent infection over 12 weeks. Treatment with oral capsules may be an effective approach to treating RCDI. Trial Registration: clinicaltrials.gov Identifier: NCT02254811. PMID- 29183075 TI - Chemical Composition and Labeling of Substances Marketed as Selective Androgen Receptor Modulators and Sold via the Internet. AB - Importance: Recent reports have described the increasing use of nonsteroidal selective androgen receptor modulators, which have not been approved by the US Food and Drug Administration (FDA), to enhance appearance and performance. The composition and purity of such products is not known. Objective: To determine the chemical identity and the amounts of ingredients in dietary supplements and products marketed and sold through the internet as selective androgen receptor modulators and compare the analyzed contents with product labels. Design and Setting: Web-based searches were performed from February 18, 2016, to March 25, 2016, using the Google search engine on the Chrome and Internet Explorer web browsers to identify suppliers selling selective androgen receptor modulators. The products were purchased and the identities of the compounds and their amounts were determined from April to August 2016 using chain-of-custody and World Anti Doping Association-approved analytical procedures. Analytical findings were compared against the label information. Exposures: Products marketed and sold as selective androgen receptor modulators. Main Outcomes and Measures: Chemical identities and the amount of ingredients in each product marketed and sold as selective androgen receptor modulators. Results: Among 44 products marketed and sold as selective androgen receptor modulators, only 23 (52%) contained 1 or more selective androgen receptor modulators (Ostarine, LGD-4033, or Andarine). An additional 17 products (39%) contained another unapproved drug, including the growth hormone secretagogue ibutamoren, the peroxisome proliferator-activated receptor-delta agonist GW501516, and the Rev-ErbA agonist SR9009. Of the 44 tested products, no active compound was detected in 4 (9%) and substances not listed on the label were contained in 11 (25%). In only 18 of the 44 products (41%), the amount of active compound in the product matched that listed on the label. The amount of the compounds listed on the label differed substantially from that found by analysis in 26 of 44 products (59%). Conclusions and Relevance: In this limited investigation involving chemical analyses of 44 products marketed as selective androgen receptor modulators and sold via the internet, most products contained unapproved drugs and substances. Only 52% contained selective androgen receptor modulators and many were inaccurately labeled. PMID- 29183077 TI - Adherence to Methodological Standards in Research Using the National Inpatient Sample. AB - Importance: Publicly available data sets hold much potential, but their unique design may require specific analytic approaches. Objective: To determine adherence to appropriate research practices for a frequently used large public database, the National Inpatient Sample (NIS) of the Agency for Healthcare Research and Quality (AHRQ). Design, Setting, and Participants: In this observational study of the 1082 studies published using the NIS from January 2015 through December 2016, a representative sample of 120 studies was systematically evaluated for adherence to practices required by AHRQ for the design and conduct of research using the NIS. Exposures: None. Main Outcomes and Measures: All studies were evaluated on 7 required research practices based on AHRQ's recommendations and compiled under 3 domains: (1) data interpretation (interpreting data as hospitalization records rather than unique patients); (2) research design (avoiding use in performing state-, hospital-, and physician level assessments where inappropriate; not using nonspecific administrative secondary diagnosis codes to study in-hospital events); and (3) data analysis (accounting for complex survey design of the NIS and changes in data structure over time). Results: Of 120 published studies, 85% (n = 102) did not adhere to 1 or more required practices and 62% (n = 74) did not adhere to 2 or more required practices. An estimated 925 (95% CI, 852-998) NIS publications did not adhere to 1 or more required practices and 696 (95% CI, 596-796) NIS publications did not adhere to 2 or more required practices. A total of 79 sampled studies (68.3% [95% CI, 59.3%-77.3%]) among the 1082 NIS studies screened for eligibility did not account for the effects of sampling error, clustering, and stratification; 62 (54.4% [95% CI, 44.7%-64.0%]) extrapolated nonspecific secondary diagnoses to infer in-hospital events; 45 (40.4% [95% CI, 30.9%-50.0%]) miscategorized hospitalizations as individual patients; 10 (7.1% [95% CI, 2.1%-12.1%]) performed state-level analyses; and 3 (2.9% [95% CI, 0.0%-6.2%]) reported physician-level volume estimates. Of 27 studies (weighted; 218 studies [95% CI, 134-303]) spanning periods of major changes in the data structure of the NIS, 21 (79.7% [95% CI, 62.5%-97.0%]) did not account for the changes. Among the 24 studies published in journals with an impact factor of 10 or greater, 16 (67%) did not adhere to 1 or more practices, and 9 (38%) did not adhere to 2 or more practices. Conclusions and Relevance: In this study of 120 recent publications that used data from the NIS, the majority did not adhere to required practices. Further research is needed to identify strategies to improve the quality of research using the NIS and assess whether there are similar problems with use of other publicly available data sets.

AB - Importance: Although wait times for hip fracture surgery have been linked to mortality and are being used as quality-of-care indicators worldwide, controversy exists about the duration of the wait that leads to complications. Objective: To use population-based wait-time data to identify the optimal time window in which to conduct hip fracture surgery before the risk of complications increases. Design, Setting, and Participants: Population-based, retrospective cohort study of adults undergoing hip fracture surgery between April 1, 2009, and March 31, 2014, at 72 hospitals in Ontario, Canada. Risk-adjusted restricted cubic splines modeled the probability of each complication according to wait time. The inflection point (in hours) when complications began to increase was used to define early and delayed surgery. To evaluate the robustness of this definition, outcomes among propensity-score matched early and delayed surgical patients were compared using percent absolute risk differences (RDs, with 95% CIs). Exposure: Time elapsed from hospital arrival to surgery (in hours). Main Outcomes and Measures: Mortality within 30 days. Secondary outcomes included a composite of mortality or other medical complications (myocardial infarction, deep vein thrombosis, pulmonary embolism, and pneumonia). Results: Among 42 230 patients with hip fracture (mean [SD] age, 80.1 years [10.7], 70.5% women) who met study entry criteria, overall mortality at 30 days was 7.0%. The risk of complications increased when wait times were greater than 24 hours, irrespective of the complication considered. Compared with 13 731 propensity-score matched patients who received surgery earlier, 13 731 patients who received surgery after 24 hours had a significantly higher risk of 30-day mortality (898 [6.5%] vs 790 [5.8%]; % absolute RD, 0.79; 95% CI, 0.23-1.35) and the composite outcome (1680 [12.2%]) vs 1383 [10.1%]; % absolute RD, 2.16; 95% CI, 1.43-2.89). Conclusions and Relevance: Among adults undergoing hip fracture surgery, increased wait time was associated with a greater risk of 30-day mortality and other complications. A wait time of 24 hours may represent a threshold defining higher risk. PMID- 29183079 TI - Wrong-Site Surgery. PMID- 29183081 TI - Salt of the Earth. PMID- 29183082 TI - Hidradenitis Suppurativa: Advances in Diagnosis and Treatment. AB - Importance: Hidradenitis suppurativa (HS) is relatively common, with the prevalence of 0.05% to 4.10%, yet many patients receive inadequate treatment. Objective: To review the diagnosis, epidemiology, and treatment of HS with an emphasis on advances in the last 5 years. Evidence Review: A literature search was conducted using PubMed, MEDLINE (Medical Subject Headings [MeSH]), and EMBASE to include recently published treatment studies (searched from September 1, 2011, to May 1, 2017). Reviews, guidelines, conference abstracts, and studies with less than 10 patients were excluded. Furthermore, internet searches for guidelines on hidradenitis suppurativa using Baidu, Bing, Google, and Qwant browsers were performed. Findings: The diagnosis of HS is made by lesion morphology (nodules, abscesses, tunnels, and scars), location (axillae, inframammary folds, groin, perigenital, or perineal), and lesion progression (2 recurrences within 6 months or chronic or persistent lesions for >=3 months). HS is more common than was previously thought based on epidemiological analysis (0.05%-4.10%). Disability from HS can be significant. Patients with HS may have significant comorbidities (eg, obesity, metabolic syndrome, diabetes, and arthritis) and increased all cause mortality (incidence rate ratio, 1.35 [95% CI, 1.15-1.59]). Antibiotic treatment with combinations of clindamycin and rifampicin, or ertapenem followed by combination rifampicin, moxifloxacin, and metronidazole for 6 months is effective. Adalimumab is effective in a significant proportion of patients and treatment with IL-1 and IL-12 receptor subunit beta 1 (Rb1) antibodies may also be useful. Tissue-sparing surgical techniques and carbon dioxide laser treatments also are available, but the evidence on clinical outcomes with these approaches is limited. Conclusions and Relevance: Hidradenitis suppurativa is more common than previously thought and may be treated by an array of pharmacological and surgical techniques. Hidradenitis suppurativa should be considered in the differential diagnosis of nodular lesions or sinus tracts present in the axillae, groin, perineal, and mammillary fold regions.

PMID- 29183086 TI - Does Posterior Condylar Offset Affect Clinical Results following Total Knee Arthroplasty? AB - Total knee arthroplasty (TKA) is an effective, durable treatment for knee osteoarthritis. However, a subset of patients experiences incomplete pain relief and ongoing dysfunction. Posterior condylar offset (PCO) has previously been shown to be associated with postoperative range of motion (ROM) following TKA; however, an association with patient-reported outcome measures (PROMs) has not been established. The purpose of this study was to evaluate the association between PCO and postoperative ROM and PROMs. A retrospective review of 970 posterior-stabilized single design TKAs was performed. Preoperative and postoperative radiographs were analyzed to measure the change in PCO and anteroposterior (AP) femoral dimension. Clinical outcome measures, including Short Form-12 physical and mental component summaries, Western Ontario and McMaster Universities Arthritis Index, and Knee Society Score were reviewed to determine if these were influenced by changes in PCO and AP dimension. PCO was increased by more than 3 mm in 15.1%, maintained (within 3 mm) in 59.6%, and decreased by more than 3 mm in 25.3% of patients. Comparing between these groups, there were no significant differences in postoperative ROM or PROM. AP dimension increased in 24.4%, maintained in 47.8%, and decreased in 27.8%. Similarly, there were no significant differences in ROM or PROM between these groups. Spearman's correlation analyses failed to identify an association between PCO and ROM or PROMs. In conclusion, increasing or decreasing PCO or AP femoral dimension with this PS TKA design did not significantly affect postoperative ROM or PROM. Similarly, maintenance of PCO within one implant size with this system compared with optimal sizing had no deleterious effect on TKA outcomes. PMID- 29183087 TI - Biomechanical Implications of an Oblique Knee Joint Line. AB - Surgical correction of multiapical deformities of the lower limb requires careful preoperative planning. Surgeons must account for the potential creation of secondary deformity, such as knee joint line obliquity, and the risks associated with accepting these changes in limb alignment. In this study, we evaluate the effect of knee joint obliquity on tibial plateau contact pressures and knee instability. Three cadaveric knees were dissected and put through biomechanical testing to simulate loading of an oblique knee joint. We observed < 1 mm femoral displacement (proxy measure of instability) between 15 degrees of varus tilt and 10 degrees of valgus tilt, and greater increases in tibial plateau contact pressures with valgus tilt than with varus tilt. Our results suggest that, if the creation of a secondary coronal plane deformity at the knee joint cannot be avoided, up to 15 degrees of varus or 10 degrees of valgus alignment can be tolerated by an otherwise structurally normal knee. PMID- 29183088 TI - [Organ Donation in Victims of Non-Traumatic Out-of-Hospital Cardiac Arrest]. AB - INTRODUCTION: The out-of-hospital cardiac-arrest (OHCA) is one of the leading causes of death. However, although previous studies showed the possibility to transplant organs from resuscitated donors, organ donation following OHCA remains seldom. We therefore initiated this study to investigate the current percentage of organ donation in victims of OHCA in a german university hospital. MATERIAL AND METHODS: We analyzed data from all victims of OHCA who were admitted to our hospital between January 1st 2008 and May 31st 2017. RESULTS: Altogether, there were 385 victims of OHCA admitted to our hospital. 126 victims of OHCA (32.8 %) survived until hospital discharge, 259 died (67.2 %), hereunder 7 victims of OHCA (1.8 %) with proven brain death. 5 victims of OCHA (1.5 %) donated their organs, and altogether 14 organs could be transplanted successfully. DISCUSSION: Organ donation following OHCA is seldom. We therefore would appreciate a more frequent diagnostics of brain death as currently not even all victims of OHCA with proven signs of brain damage in the computed tomography receive further diagnostics to confirm the diagnosis of brain death. PMID- 29183089 TI - Successful Treatment of Estrogen Excess in Primary Bilateral Macronodular Adrenocortical Hyperplasia with Leuprolide Acetate. AB - Primary bilateral macronodular adrenocortical hyperplasia (PBMAH) is an uncommon cause of adrenal Cushing syndrome (CS) in which cortisol and occasionally other steroid hormones can be secreted under the influence of aberrantly expressed G protein coupled receptors (GPCRs) in the adrenal cortex. We describe the unique case of a 64-year-old postmenopausal female with PBMAH whose adrenal lesions expressed luteinizing hormone receptors (LHr). She presented initially with CS and underwent right adrenalectomy; a few years later she presented with macromastia and mastodynia, possibly due to estrogen excess from her remaining left adrenocortical masses. Testing before and after treatment with quarterly leuprolide acetate therapy and immunohistochemistry on tissue and targeted sequencing of the genes of interest were performed. Tissue from the patient's right adrenal was tested for P450 aromatase (CYP19A1) and LHr expression; both were expressed throughout the hyperplastic cortex, although expression was more intense in the adenomatous areas. Targeted sequencing revealed a pathogenic PDE11A mutation, as well as variants in the ARMC5 and INHA genes. PDE11A expression was decreased in the adenoma but there was no loss of heterozygosity for the PDE11A locus. Because of the clinical presentation and LHr expression, quarterly leuprolide acetate therapy was started. Shortly after initiation of therapy, the patient reported decreased breast size and pain; she remains well controlled to date, after 10 years of treatment. This is the first description of a patient with PBMAH presenting with severe macromastia and mastodynia from what appears to be excess estrogen production from her adrenal tumor. The patient had a long-lasting response to chronic leuprolide acetate treatment, showing that drug therapy exploiting the aberrant receptor expression in PBMAH is possible even in the absence of cortisol overproduction. PMID- 29183091 TI - Systematic Review of the Epidemiology and Natural History of the Metabolic Vascular Syndrome and its Coincidence with Type 2 Diabetes Mellitus and Cardiovascular Diseases in Different European Countries. AB - The objectives of this systematic review were to estimate the incidence, prevalence and natural history of the metabolic (vascular) syndrome (MVS) among adults in different European countries. Furthermore, we assessed its co-incidence with type 2 diabetes (T2DM) and cardiovascular diseases (CVD). PubMed, MedLine, and EMBASE (via Ovid) were searched for relevant studies. After reading 116 full text articles to find eligible ones, 66 publications met our inclusion criteria. Data for the incidence are based on a study from Portugal, in which the incidence rate for the MVS was 47.2/1000 person-years. Prevalence varied strongly depending on country and definition. The lowest was found in the United Kingdom (3%), the highest in Finland (71.7%). No article that deals with the natural history of the MVS was found. Considering the co-existence of MVS and T2DM, it ranged between 2% (United Kingdom) and 74.4% (Spain). The co-occurrence of MVS and CVD ranged from 2.8% (Italy) up to 52% (Netherlands). Coronary heart disease (CHD) varied between 1.2% and 44.2%. With regard to peripheral artery disease (PAD), values between 3.3% and 59.8% were found. Due to the many different definitions of the MVS, a comparison is very difficult. Overall prevalence ranged between 3% and 71.7% depending on definition, age, and country. An association between MVS and T2DM as well as several CVD can be assumed. PMID- 29183090 TI - Serum Vitamin D Status, Vitamin D Receptor Polymorphism, and Glucose Homeostasis in Healthy Subjects. AB - Low vitamin D status has been frequently associated with impaired glucose metabolism. We examined associations between 25-hydroxyvitamin D (25-OH-D) and several parameters of glucose homeostasis in virtually healthy subjects, and explored possible interaction with vitamin D receptor (VDR) polymorphism. Nondiabetic subjects without chronic medication or any known significant manifest disease were selected from large general-population based population survey. Insulin sensitivity and beta cell secretion were calculated by homeostasis model assessment (HOMA) and soluble isoform of receptor for advanced glycation end products (sRAGE) using commercial ELISA. Subjects were also genotyped for rs2228570 polymorphism of VDR. After adjustment for potential confounders, we observed a significant relationship between 25-OH-D and fasting glycemia (beta coefficient=-5.904; p=0.002) or insulin sensitivity (beta=0.042; p=0.001), but not with beta cell secretion or sRAGE. We found also an interaction with VDR polymorphism. Subjects with low 25-OH-D and AA genotype had significantly lower insulin sensitivity than those with GG genotype plus highest 25-OH-D concentrations (107.3% vs. 183.9%, p=0.021). In conclusion, low vitamin D status was in virtually healthy subjects associated with decreased insulin sensitivity, namely in those with GG genotype of rs2228570 VDR polymorphism. PMID- 29183092 TI - [Methamphetamine Consumption During Pregnancy and its Effects on Neonates]. AB - OBJECTIVE: Methamphetamine (MA) has become one of the most commonly used illegal drugs during pregnancy. We sought to determine how MA abuse modifies pregnancy outcomes and the health of the newborn infants. Patients 102 newborns from mothers with antenatal MA consumption were admitted to the University Hospital Leipzig from 2004-2015. METHODS: The effects of MA abuse on pregnancy outcomes and neonates were researched in a retrospective controlled study. We analysed the date of pregnancy detection, number of antenatal preventive examinations, body measurements of the neonates, duration of hospitalization, rate of preterm infants, congenital malformations and symptoms of neonatal abstinence syndrome. RESULTS: The majority of pregnancies of MA abusing women were diagnosed during the 2. trimester and they had a median of 4 prenatal care visits. The group of MA exposed neonates includes twice as many preterm neonates as the control group (MA:20,6%; CG:10,7%). The consumption was associated with intrauterine growth restriction, an increased incidence of poor cardio respiratory adaptation, cardiac defects and a floppy muscle tone. The median time of hospitalization was 10d as compared to a control group (CG:5d). Special care was needed in 44% of the neonates (CG:0,98%). The median age of primiparous women was 22.5 yr (CG:30 yr), 4.9% were married (CG:38%). 57 of 102 women were unemployed. CONCLUSION: Because of the adverse effects of perinatal MA abuse a multidisciplinary team is necessary to detect the consumption, to alleviate side effects and to provide efficient medical care for the newborns. Psychological and social support for the families are also important. PMID- 29183093 TI - Multiple Sclerosis with Onset Younger Than 10 Years in Turkey. AB - OBJECTIVE: To identify the demographics, clinical characteristics, disease course, treatment patterns, and disability levels of multiple sclerosis (MS) patients with onset under the age of 10 years (early onset multiple sclerosis, EOMS). METHODS: EOMS patients were reviewed retrospectively in detailed records from 27 child neurology centers. Patients with preschool (<=7 years) and school age (>7 years) onset were compared. RESULTS: There were 30 children (16 girls, 14 boys) who have disease onset between 4 and 10 (mean8.1 +/- 1.8) years. MS was relapsing-remitting in 29 (96.7%) and primary progressive in one (3.3%) of the patients. In patients with onset <=7 years, motor symptoms (54.5%) and encephalopathy (45.5%) predominated, while in those with onset >7 years brainstem (42.1%), sensory (26.3%), and optic nerve (26.3%) involvement were the most frequent presentations. CONCLUSIONS: MS starting <=7 years differs from the 7-10 year-old group by the higher rate of motor symptoms and more attacks in the first year: the latter suggests a more inflammatory character for EOMS. PMID- 29183094 TI - Impact of Intended Mode of Delivery on Outcomes in Preterm Growth-Restricted Fetuses. AB - BACKGROUND: Scheduled cesarean is frequently performed for fetal growth restriction due to concerns for fetal intolerance of labor. OBJECTIVE: We compared neonatal outcomes in preterm growth-restricted fetuses by intended mode of delivery. STUDY DESIGN: We performed a retrospective cohort study of indicated preterm births with prenatally diagnosed growth restriction from 2011 to 2014 at a single institution. Patients were classified by intended mode of delivery. The primary outcome was a composite of adverse neonatal outcomes, including perinatal death, cord blood acidemia, chest compressions during neonatal resuscitation, seizures, culture-proven sepsis, necrotizing enterocolitis, and grade III-IV intraventricular hemorrhage. Secondary analysis was performed examining the impact of umbilical artery Dopplers. RESULTS: Of 101 fetuses with growth restriction, 75 underwent planned cesarean deliveries. Of those induced, 46.2% delivered vaginally. Delivery by scheduled cesarean was not associated with a decreased risk of the composite outcome (adjusted odds ratio [aOR], 1.61; 95% confidence interval [CI], 0.45-5.78), even when only those with abnormal umbilical artery Dopplers were considered (aOR, 2.8; 95% CI, 0.40-20.2). CONCLUSION: In this cohort, planned cesarean was not associated with a reduction in neonatal morbidity, even when considering only those with abnormal umbilical artery Dopplers. In otherwise appropriate candidates for vaginal delivery, fetal growth restriction should not be considered a contraindication to trial of labor. PMID- 29183095 TI - The Independent Contribution of Uterine Blood Flow to Birth Weight and Body Composition in Smoking Mothers. AB - OBJECTIVE: This study aims to evaluate the relationship of maternal smoking to uterine artery hemodynamics and examine independent contributions to birth weight and fetal body composition. STUDY DESIGN: Women were enrolled in a prospective randomized controlled study targeting smoking abstinence. Uterine artery Doppler ultrasound was performed and volumetric blood flow was calculated. Third trimester ultrasound estimates of fetal body composition were performed and birth weight was recorded. RESULTS: Uterine artery volumetric flow and resistance index (RI) were significantly correlated with birth weight adjusted for gestational age (R = 0.35, p = 0.002; R = - 0.27, p = 0.02). Volumetric flow was significantly associated with fetal fat mass (R = 0.30, p = 0.018). Smoking status did not have significant effects on lean body mass (t [61] = 0.60, p = 0.55), fat mass (t [61] = 1.67, p = 0.10), or volumetric flow (t = 0.86, df = 87, p = 0.39). Stepwise regression identified volumetric flow (beta = 0.81, 95% confidence interval [CI]: 0.35-1.27, p < 0.001), maternal prepregnancy body mass index (beta = 16.04, 95% CI: 2.57-29.50, p = 0.02), and fetal sex (beta = 346.28, 95% CI: -532.64 to 159.91, p < 0.001, where male = 0 and female = 1) as independent contributors to birth weight adjusted for gestational age. CONCLUSION: No direct relationship of smoking to uterine artery hemodynamics was demonstrated. Volumetric flow was an independent contributor to birth weight and was associated with fetal fat deposition, while smoking was not independently associated with either outcome. PMID- 29183096 TI - Morbidity Associated with Fetal Macrosomia among Women with Diabetes Mellitus. AB - OBJECTIVE: This article aims to compare the composite maternal and neonatal morbidities (CMM and CNM, respectively) between macrosomic (>=4,000 g) and nonmacrosomic (<4,000 g) newborns among women with diabetes mellitus (DM). METHODS: Maternal demographic and peripartum outcome data (N = 1,260) were collected from a retrospective cohort. CMM included chorioamnionitis/endometritis, wound infection, shoulder dystocia, eclampsia, pulmonary edema, admission for hypoglycemia, 3rd/4th degree perineal laceration, and death. CNM included 5-minute Appearance, Pulse, Grimace, Activity and Respiration (APGAR) score of <4, neonatal intensive care unit (NICU) admission, respiratory distress syndrome, mechanical ventilation, intraventricular hemorrhage grade III/IV, necrotizing enterocolitis stage II/III, hypoglycemia, hypocalcemia, bronchopulmonary dysplasia, sepsis, seizures, hyperbilirubinemia, and death. Multivariable Poisson regression models with robust error variance were used to calculate adjusted relative risk (aRR) and 95% confidence interval (CI). RESULTS: The study population consisted of 967 subjects, including 854 (88.3%) nonmacrosomic and 113 (11.7%) macrosomic infants. After adjustment, the risk of CMM was higher among macrosomic deliveries (aRR = 4.08, 95% CI = 2.45 6.80). The risk of CNM was also higher among macrosomic deliveries (aRR = 1.77, 95% CI = 1.39-2.24). Macrosomia was associated with an increased risk in NICU admission, hypoglycemia, and hyperbilirubinemia. CONCLUSION: Among DM deliveries, macrosomia was associated with a fourfold higher risk of CMM and almost twofold higher risk of CNM.

AB - OBJECTIVE: To identify clinical factors those predict the need for patent ductus arteriosus (PDA) treatment in preterm neonates who had received prophylactic indomethacin. PATIENTS AND METHODS: Preterm neonates with <28 weeks' gestational age admitted to level III neonatal intensive care units (NICUs) in Canada between 2010 and 2015 and who had received prophylactic indomethacin were included. Primary outcome was surgical ligation of PDA, while secondary outcomes were any PDA treatment and common neonatal morbidities. RESULTS: Of the 7,024 eligible neonates, 843 (12%) neonates had received prophylactic indomethacin. Of them, 84 neonates (10%) required surgical ligation while 367 neonates (44%) received medical or surgical treatment for PDA. Logistic regression analyses identified gestational age (odds ratio [OR]: 0.71, 95% confidence interval [CI]: 0.58-0.87) and outborn status (OR: 2.07, 95% CI: 1.09-3.93) as predictors for surgical ligation. Maternal hypertension (OR: 0.57, 95% CI: 0.37-0.89), rupture of membranes (ROM) >=24 hours (OR: 0.68, 95% CI: 0.48-0.96), and surfactant treatment (OR: 1.70, 95% CI: 1.09-2.66) were predictors for medical or surgical treatment of PDA. CONCLUSION: In extremely preterm neonates who had received prophylactic indomethacin, gestational age and outborn status were predictors for surgical ligation of PDA, while maternal hypertension, ROM >=24 hours, and surfactant treatment were associated with the medical or surgical treatment of PDA. PMID- 29183098 TI - Ultrasound-Guided Cannulation of the Brachiocephalic Vein in Neonates and Preterm Infants: A Prospective Observational Study. AB - INTRODUCTION: Percutaneous central venous catheter (CVC) insertion is a challenging procedure in neonates, especially in preterm infants. OBJECTIVE: This study aims to describe the technical success and safety profile of ultrasound (US)-guided brachiocephalic vein (BCV) cannulation in neonates. METHODS: Prospective observational study. Neonates admitted to the neonatal intensive care unit (NICU) in whom US-guided cannulation of the BCV was attempted were eligible. Outcomes included first attempt success rate, the overall success rate, the number of attempts, the cannulation time, immediate mechanical complications, catheter indwelling days, and late complications. RESULTS: A total of 40 procedures in 37 patients were included. Median weight and age at the time of cannulation were 1.85 kg (0.76-4.8) and 13 days (3-31), respectively. First attempt and overall success rates were 29 (72.5%) and 38 (95%), respectively. No major complications were observed. Catheter-associated infection rate was 2.4/1,000 catheter days. There were no difference in outcomes between low weight preterm infants (<1.5 kg) and the rest of the cohort. There was no linear relationship between weight at time of insertion and the number of puncture attempts (r = 0.250; p = 0.154) or cannulation time (r = 0.257; p = 0.142). CONCLUSION: US-guided cannulation of the BCV may be considered in acutely ill neonates, including small preterm infants, who need a large bore CVC. PMID- 29183099 TI - Neonatal Outcomes Differ after Spontaneous and Indicated Preterm Birth. AB - OBJECTIVE: Preterm birth (PTB) at <37 weeks of gestation complicates 10% of pregnancies and requires accurate counseling regarding anticipated neonatal outcomes. PTB classification as spontaneous or indicated is commonly used to cluster PTB into subtypes, but whether neonatal outcomes differ by PTB subtype is unknown. We tested the hypothesis that neonatal morbidity differs based on subtype of PTB. METHODS: We performed a retrospective cohort study of live-born, non-anomalous preterm infants from 2004 to 2008. Spontaneous PTB was defined as PTB from spontaneous preterm labor or preterm rupture of membranes. Indicated PTB was defined as PTB from any maternal or fetal medical complication necessitating delivery. The primary outcome was a composite of early respiratory morbidity. Secondary outcomes included late composite respiratory morbidity and other neonatal morbidities. RESULTS: Of 1,223 preterm neonates, 60.9% were born after spontaneous PTB and 30.1% after indicated PTB. Composite early respiratory morbidity was significantly higher after indicated PTB versus spontaneous PTB (1.3, 95% confidence interval [CI] 1.2-1.4). Composite late respiratory morbidity (1.8, 95% CI 1.3-2.3) and neonatal death (2.8, 95% CI 1.5-5.1) were also significantly higher after indicated PTB versus spontaneous PTB. CONCLUSION: Neonatal respiratory outcomes and death differ according to PTB subtype. PTB subtype should be considered while counseling families and anticipating neonatal outcomes after PTB. PMID- 29183100 TI - [Access to Inpatient Rehabilitation of Methamphetamine Addiction - Barriers and Potential for Improvement from the Experts' Perspective]. AB - Objective The study explores central barriers impeding the access to inpatient rehabilitation of methamphetamine addicts and investigates how these barriers can be tackled. Methods The experiences and perspectives of experts from different healthcare sectors were explored within 39 semi-structured individual interviews. Subsequently, the results gathered in the course of the individual interviews were discussed within 2 inter-professional focus groups. All interviews and focus group discussions were analyzed according to the interpretive analysis method of Meuser & Nagel. Results Structural issues in particular impair the access to inpatient rehabilitation of methamphetamine dependents. This includes impeded access to rehabilitation via general practitioners, rare implementation of seamless transitions, capacity problems as well as non-transparent procedures in terms of treatment facility allocations. Conclusion Various barriers impair access to inpatient rehabilitation of methamphetamine dependents. It is important to increase awareness of methamphetamine addicts and their specific needs particularly among general practitioners. Furthermore, it is important to ensure seamless transitions from detoxification treatment to inpatient rehabilitation and to reduce waiting periods as well as to provide well-differentiated and appropriate rehabilitation options. PMID- 29183101 TI - [The Significance of Work Motivation for Rehabilitation Success]. AB - AIM OF THIS STUDY: Apart from the reduction of symptoms and the restoration of working ability, return to work is a long-term goal of medical rehabilitation. The aim of this study is to analyze the influence of work motivation on the outcome of rehabilitation. METHODS: The data basis consists of N=998 patients at the psychosomatic department of the Oberharz Rehabilitation Center as well as data from insurance accounts. Using multiple linear regression analysis the predictive power of work motivation on rehabilitation outcome as well as different facets of work motivation in their function as predictors are analyzed. RESULTS: Only minor statistical relations could be found between work motivation and rehabilitation success when also taking employment status of the previous year and subjective vocational disability into account. A small predictive power can be attributed to work motivation as a factor in rehabilitation success in the sense of a reduction of symptoms. Particular facets of work motivation are suitable to predict rehabilitation success. Patients with a work motivation risk profile differ from patients with a normal work motivation profile as regards their capacity to work in the year following rehabilitation treatment. CONCLUSION: Work motivation represents a relevant construct in rehabilitation success but is strongly influenced by individual factors. During rehabilitation, individual problems which influence work motivation should be taken into account more strongly. PMID- 29183102 TI - [Spectrum and Frequency of ADHD-Related Symptoms and Minimal Cerebral Brain Dysfunctions in Psychosomatic Inpatients]. AB - Objective ADHD (attention deficit hyperactivity disorders) and MCD (minimal cerebral dysfunctions) can impair participation. They pose difficult diagnostic problems. Aim of the present study has been to describe the frequency and the spectrum of ADHD and MCD in psychosomatic inpatients. Methods 1453 psychosomatic inpatients filled in the ADHS-SB and the MCD-TLS-FB screening for self-reported ADHD and minimal cerebral dysfunctions. Prevalence rates were calculated depending on different intensities of symptoms. Results According to the ADHS-SB 49.5% of the patients met the criteria of an adult ADHD when taking all intensities of symptoms into account. The prevalence rate decreases to 14,6% if moderate to severe symptoms and to 1% if only severe symptoms ratings were recognized. Additional to core symptoms of attentions deficit and hyperactivity patients with ADHD reported about problems with orientation, memory, cognition, emotion regulation, vegetative stability and movement. Discussion ADHD-related symptoms and minimal cerebral dysfunctions are frequently seen in psychosomatic inpatients. In clinical practice the full spectrum of TLS must be taken into account as they all can impair participation depending on context requirements. PMID- 29183103 TI - [ICF-Checklist to Evaluate Inclusion of Elderlies with Intellectual Disability - Psychometric Properties]. AB - Background An instrument should have been developed to measure participation as one possible criterion to evaluate inclusion of elderly people with intellectual disability. The ICF was utilized, because participation is one part of health related functioning, respectively disability. Furthermore ICF includes environmental factors (contextual factors) and attaches them an essentially influence on health related functioning, in particular on participation. Thus ICF Checklist additionally identifies environmental barriers for elimination. Methodology A linking process with VINELAND-II yielded 138 ICF items for the Checklist. The sample consists of 50 persons with a light or moderate intellectual disability. Two-thirds are female and the average age is 68. They were directly asked about their perceived quality of life. Additionally, proxy interviews were carried out with responsible staff members concerning necessary support and behavioral deviances. The ICF Checklist was administered twice, once (t2) the current staff member should rate health related functioning at the given time and in addition, a staff member who knows the person at least 10 years before (t1) should rate the former functioning. Content validity was investigated with factor analysis and criterion validity with correlational analysis related to supports need, behavioral deviances and perceived quality of life. Quantitative analysis was validated by qualitative content analysis of patient documentation. Results Factor analysis shows logical variable clusters across the extracted factors but neither interpretable factors. The Checklist is reliable, valid related to the chosen criterions and shows the expected age-related shifts. Qualitative analysis corresponds with quantitative data. Consequences/Conclusion ICF Checklist is appropriate to manage and evaluate patient-centered care. PMID- 29183104 TI - Prevalence and Progression Rate of Diabetic Retinopathy in Type 2 Diabetes Patients in Correlation with the Duration of Diabetes. AB - AIMS: We examined prevalence and progression of retinopathy in dependence on diabetes duration in order to estimate the probability of progression. PATIENTS/METHODS: In a retrospective cohort-analysis from an academic outpatient department of endocrinology and metabolic diseases we analyzed 17461 consultations of 4513 patients with DM2 from 1987 to 2014. 50.3% of the patients (n=2272) had at least one documented result of funduscopy. RESULTS: 25.8% of the patients had retinopathy (20.2% non-proliferative, 4.7% proliferative, 0.7% were not classified, 0.1% blindness). The prevalence of retinopathy in dependence on diabetes duration was 1.1% at diagnosis, 6.6% after 0<5 years, 12% after 5<10 years, 24% after 10<15 years, 39.9% after 15<20 years, 52.7% after 20<25 years, 58.7% after 25<30 years and 63% after >=30 years. In a subset of 586 (25.7%) patients with retinal photography of 3 consecutive years 7.0% showed deterioration after one and 12.2% after two years; 2.6% improved after one and 2.8% after two years. 201 (34.3%) of this group had<10 years diabetes and lower deterioration (4.5% worsened after one and 9.5% after two years). Their retinopathy mainly transformed from no retinopathy to non-proliferative. Four patients (2.0%) developed proliferative retinopathy. CONCLUSIONS/INTERPRETATIONS: Within the first 10 years of diabetes duration, the prevalence of retinopathy is low and the progression infrequent. Most patients have a non-proliferative form which can be reversible and rarely requires interventions. Patients with DM2 without retinopathy and good glycaemic control do not run into additional risk from expanding funduscopy intervals to biennial. PMID- 29183105 TI - Relation of Carotid Artery Plaque to Coronary Heart Disease and Stroke in Chinese Patients: Does Hyperglycemia Status Matter? AB - OBJECTIVE: To examine the association of carotid artery plaque with the incident coronary heart disease and stroke events in Chinese patients and explore whether the association differs between patients with and without hyperglycemia. METHODS: We evaluated plaque, and blood pressure, total cholesterol, triglycerides, high density lipoprotein cholesterol, low-density lipoprotein cholesterol, fasting serum insulin, fasting plasma glucose, 2 h postprandial glucose and Homeostasis model assessment of insulin resistance in 253 Chinese patients. T-test and X2 test were used to compare the clinical characteristics and Binary logistic regression was applied to analyze the association of coronary heart disease and stroke between patients with and without hyperglycemia. RESULTS: Among 253 patients, 162 patients had hyperglycemia (i. e., diabetes, impaired glucose regulation and stress induced hyperglycemia) and 155 (61.3%) patients had plaque. Fasting plasma glucose, 2 h postprandial glucose and Homeostasis model assessment of insulin resistance, triglycerides, plaque were significantly higher in the hyperglycemia group than non-hyperglycemia. The incident coronary heart disease and stroke events in patients with plaque were 2.254 (95%CI,1.203-4.224) and 2.437 (95%CI,1.042-5.701) times higher than those without plaque, respectively. Among hyperglycemia subgroup, plaque was an independent risk factor for coronary heart disease (OR,3.075,95%CI,1.353-6.992) and stroke (OR,3.571,95%CI,1.460 8.737). The slopes (associations between coronary heart disease/stroke and plaque) were steeper in the hyperglycemia group than those in the non hyperglycemia group (coronary heart disease OR,3.075 vs. 2.614; stroke OR,3.571 vs. 3.307). CONCLUSIONS: The incident coronary heart disease and stroke events in patients with plaque were higher than those without plaque, and this difference was more pronounced for patients with hyperglycemia vs. those without hyperglycemia. PMID- 29183106 TI - Monogenic Diabetes Not Caused By Mutations in Mody Genes: A Very Heterogenous Group of Diabetes. AB - Monogenic diabetes represents a heterogeneous group of disorders resulting from a single gene defect leading to disruption of insulin secretion or a reduction in the number of beta cells. Despite the classification of monogenic diabetes into neonatal diabetes or maturity onset diabetes of the young (MODY) according to age of onset, not every case can be classified into those 2 groups. We evaluated patients with monogenic diabetes diagnosed during the last 10 year period. Type 1 DM, MODY, and patients with negative autoantibodies and no mutation in a known gene were excluded from the study. Thirteen patients were diagnosed with monogenic diabetes in Department of Pediatric Endocrinology, Ankara University School of Medicine, Ankara, Turkey. Five of them were diagnosed after 6 months of age. Five had a KATP channel defect. Mutations in genes resulting in destruction of beta cells were detected in 7 patients, with 4 cases having a WFS, 2 an LRBA, and one a IL2RA mutation. Additional systemic findings were seen in 6/13 patients, with 5/6 having severe immune system dysfunction. Treatment with sulphonylurea was successful in two patients.. The other patients were given insulin in differing doses. Four patients died during follow-up, three of which had immune system dysfunction. Monogenic diabetes can be diagnosed after 6 months of age, even with positive autoantibodies. Immune dysfunction was a common feature in our cohort and should be investigated in all patients with early-onset monogenic diabetes. Mortality of patients with monogenic diabetes and additional autoimmunity was high in our cohort and is likely to reflect the multisystem nature of these diseases. PMID- 29183107 TI - Insulin-sensitising drugs (metformin, rosiglitazone, pioglitazone, D-chiro inositol) for women with polycystic ovary syndrome, oligo amenorrhoea and subfertility. AB - BACKGROUND: Polycystic ovary syndrome (PCOS) is characterised by infrequent or absent ovulation, and high levels of androgens and insulin (hyperinsulinaemia). Hyperinsulinaemia occurs secondary to insulin resistance and is associated with increased risk of cardiovascular disease and diabetes mellitus. Insulin sensitising agents such as metformin may be effective in treating PCOS-related anovulation. OBJECTIVES: To evaluate the effectiveness and safety of insulin sensitising drugs in improving reproductive and metabolic outcomes for women with PCOS undergoing ovulation induction. SEARCH METHODS: We searched the following databases from inception to January 2017: Cochrane Gynaecology and Fertility Group Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL. We searched registers of ongoing trials and reference lists from relevant studies. SELECTION CRITERIA: We included randomised controlled trials of insulin sensitising drugs compared with placebo, no treatment, or an ovulation-induction agent for women with oligo and anovulatory PCOS. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for eligibility and bias. Primary outcomes were live birth rate and gastrointestinal adverse effects. Secondary outcomes included other pregnancy outcomes, menstrual frequency and metabolic effects. We combined data to calculate pooled odds ratios (ORs) and 95% confidence intervals (CIs). We assessed statistical heterogeneity using the I2 statistic and reported quality of the evidence for primary outcomes using GRADE methodology. MAIN RESULTS: We assessed the interventions metformin, clomiphene citrate, metformin plus clomiphene citrate, D-chiro-inositol, rosiglitazone and pioglitazone. We compared these with each other, placebo or no treatment. We included 48 studies (4451 women), 42 of which investigated metformin (4024 women). Evidence quality ranged from very low to moderate. Limitations were risk of bias (poor reporting of methodology and incomplete outcome data), imprecision and inconsistency. Metformin versus placebo or no treatmentThe evidence suggests that metformin may improve live birth rates compared with placebo (OR 1.59, 95% CI 1.00 to 2.51, 4 studies, 435 women, I2 = 0%, low-quality evidence). The metformin group experienced more gastrointestinal side effects (OR 4.76, 95% CI 3.06 to 7.41, 7 studies, 670 women, I2 = 61%, moderate-quality evidence) but had higher rates of clinical pregnancy (OR 1.93, 95% CI 1.42 to 2.64, 9 studies, 1027 women, I2 = 43%, moderate-quality evidence), ovulation (OR 2.55, 95% CI 1.81 to 3.59, 14 studies, 701 women, I2 = 58%, moderate-quality evidence) and menstrual frequency (OR 1.72, 95% CI 1.14 to 2.61, 7 studies, 427 women, I2 = 54%, low quality evidence). There was no clear evidence of a difference in miscarriage rates (OR 1.08, 95% CI 0.50 to 2.35, 4 studies, 748 women, I2 = 0%, low-quality evidence). Metformin plus clomiphene citrate versus clomiphene citrate alone There was no conclusive evidence of a difference between the groups in live birth rates (OR 1.21, 95% CI 0.92 to 1.59, 9 studies, 1079 women, I2 = 20%, low-quality evidence), but gastrointestinal side effects were more common with combined therapy (OR 3.97, 95% CI 2.59 to 6.08, 3 studies, 591 women, I2 = 47%, moderate quality evidence). However, the combined therapy group had higher rates of clinical pregnancy (OR 1.59, 95% CI 1.27 to 1.99, 16 studies, 1529 women, I2 = 33%, moderate-quality evidence) and ovulation (OR 1.57, 95% CI 1.28 to 1.92, 21 studies, 1624 women, I2 = 64%, moderate-quality evidence). There was a statistically significant difference in miscarriage rate per woman, with higher rates in the combined therapy group (OR 1.59, 95% CI 1.03 to 2.46, 9 studies, 1096 women, I2 = 0%, low-quality evidence) but this is of uncertain clinical significance due to low-quality evidence, and no clear difference between groups when we analysed miscarriage per pregnancy (OR 1.30, 95% CI 0.80 to 2.12, 8 studies; 400 pregnancies, I2 = 0%, low-quality evidence). Metformin versus clomiphene citrateWhen all studies were combined, findings for live birth were inconclusive and inconsistent (OR 0.71, 95% CI 0.49 to 1.01, 5 studies, 741 women, I2 = 86%, very low-quality evidence). In subgroup analysis by obesity status, obese women had a lower birth rate in the metformin group (OR 0.30, 95% CI 0.17 to 0.52, 2 studies, 500 women, I2 = 0%, very low-quality evidence), while data from the non-obese group showed a possible benefit from metformin, with high heterogeneity (OR 1.71, 95% CI 1.00 to 2.94, 3 studies, 241 women, I2 = 78%, very low-quality evidence). Similarly, among obese women taking metformin there were lower rates of clinical pregnancy (OR 0.34, 95% CI 0.21 to 0.55, 2 studies, 500 women, I2 = 0%, very low-quality evidence) and ovulation (OR 0.29, 95% CI 0.20 to 0.43 2 studies, 500 women, I2 = 0%, low-quality evidence) while among non-obese women, the metformin group had more pregnancies (OR 1.56, 95% CI 1.05 to 2.33, 5 studies, 490 women, I2 = 41%, very low-quality evidence) and no clear difference in ovulation rates (OR 0.81, 95% CI 0.51 to 1.28, 4 studies, 312 women, low quality evidence, I2=0%). There was no clear evidence of a difference in miscarriage rates (overall: OR 0.92, 95% CI 0.50 to 1.67, 5 studies, 741 women, I2 = 52%, very low-quality evidence). D-chiro-inositol (2 studies), rosiglitazone (1 study) or pioglitazone (1 study) versus placebo or no treatmentWe were unable to draw conclusions regarding other insulin-sensitising drugs as no studies reported primary outcomes. AUTHORS' CONCLUSIONS: Our updated review suggests that metformin alone may be beneficial over placebo for live birth, although the evidence quality was low. When metformin was compared with clomiphene citrate, data for live birth were inconclusive, and our findings were limited by lack of evidence. Results differed by body mass index (BMI), emphasising the importance of stratifying results by BMI. An improvement in clinical pregnancy and ovulation suggests that clomiphene citrate remains preferable to metformin for ovulation induction in obese women with PCOS.An improved clinical pregnancy and ovulation rate with metformin and clomiphene citrate versus clomiphene citrate alone suggests that combined therapy may be useful although we do not know whether this translates into increased live births. Women taking metformin alone or with combined therapy should be advised that there is no evidence of increased miscarriages, but gastrointestinal side effects are more likely. PMID- 29183108 TI - Enhanced Efficiency and Long-Term Stability of Perovskite Solar Cells by Synergistic Effect of Nonhygroscopic Doping in Conjugated Polymer-Based Hole Transporting Layer. AB - A face-on oriented and p-doped semicrystalline conjugated polymer, poly[(2,5 bis(2-hexyldecyloxy)phenylene)-alt-(5,6-difluoro-4,7-di(thiophen-2 yl)benzo[c][1,2,5]-thiadiazole)] (PPDT2FBT), was studied as a hole-transport layer (HTL) in methylammonium lead triiodide-based perovskite solar cells (PVSCs). PPDT2FBT exhibits a mid-band gap (1.7 eV), high vertical hole mobility (7.3 * 10-3 cm2/V.s), and well-aligned frontier energy levels with a perovskite layer for efficient charge transfer/transport, showing a maximum power conversion efficiency (PCE) of 16.8%. Upon doping the PPDT2FBT HTL with a nonhygroscopic Lewis acid, tris(pentafluorophenyl)borane (BCF, 2-6 wt %), the vertical conductivity was improved by a factor of approximately 2, and the resulting PCE was further improved up to 17.7%, which is higher than that of standard PVSCs with 2,2',7,7'-tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (spiro OMeTAD) as an HTL. After BCF doping, the clearly enhanced carrier diffusion coefficient, diffusion length, and lifetime were measured using intensity modulated photocurrent and photovoltage spectroscopy. Furthermore, compared to the standard PVSCs with spiro-OMeTAD, the temporal device stability was remarkably improved, preserving the ~60% of the original PCE for 500 h without encapsulation under light-soaking condition (1 sun AM 1.5G) at 85 degrees C and 85% humidity, which is mainly due to the highly crystalline conjugated backbone of PPDT2FBT and nonhygroscopic nature of BCF. In addition, formamidinium lead iodide/bromide (FAPbI3-xBrx)-based PVSCs with the BCF-doped PPDT2FBT as an HTL was also prepared to show 18.8% PCE, suggesting a wide applicability of PPDT2FBT HTL for different types of PVSCs.

PMID- 29183110 TI - Hyaluronic Acid-Based pH-Sensitive Polymer-Modified Liposomes for Cell-Specific Intracellular Drug Delivery Systems. AB - For the enhancement of therapeutic effects and reduction of side effects derived from anticancer drugs in cancer chemotherapy, it is imperative to develop drug delivery systems with cancer-specificity and controlled release function inside cancer cells. pH-sensitive liposomes are useful as an intracellular drug delivery system because of their abilities to transfer their contents into the cell interior through fusion or destabilization of endosome, which has weakly acidic environment. We earlier reported liposomes modified with various types of pH sensitive polymers based on synthetic polymers and biopolymers as vehicles for intracellular drug delivery systems. In this study, hyaluronic acid (HA)-based pH sensitive polymers were designed as multifunctional polymers having not only pH sensitivity but also targeting properties to cells expressing CD44, which is known as a cancer cell surface marker. Carboxyl group-introduced HA derivatives of two types, MGlu-HA and CHex-HA, which have a more hydrophobic side chain structure than that of MGlu-HA, were synthesized by reaction with various dicarboxylic anhydrides. These polymer-modified liposomes were stable at neutral pH, but showed content release under weakly acidic conditions. CHex-HA-modified liposomes delivered their contents into CD44-expressing cells more efficiently than HA-modified or MGlu-HA-modified liposomes or unmodified liposomes, whereas the same liposomes were taken up only slightly by cells expressing CD44 proteins less. Competition assay using free HA or other polymers revealed that HA derivative-modified liposomes might be recognized by CD44. Therefore, HA derivative-modified liposomes are useful as cell-specific intracellular drug delivery systems. PMID- 29183112 TI - Critical Point Confluence Phenomenon. AB - Experimental observation of coexisting isotropic chiral liquids for a single molecular substance has motivated creation of a simple lattice model to investigate phase transitions in such systems. Specifically, this model permits the simultaneous existence of two distinct types of critical points, the familiar liquid-vapor case, and a case involving spontaneous chiral symmetry breaking within the fluid system. The molecular interactions involved may extend beyond nearest neighbor lattice cells. The mean field approximation has been invoked to attain explicit results, which include a description of the singular situation for which the two critical points undergo confluence in the temperature-density plane. In particular, this confluence enhances the chiral symmetry breaking phenomenon, leading to a modified critical exponent. PMID- 29183111 TI - Remote Activation of a Nanopore for High-Performance Genetic Detection Using a pH Taxis-Mimicking Mechanism. AB - Aerolysin protein pore has been widely used for sensing peptides and proteins. However, only a few groups explored this nanopore for nucleic acids detection. The challenge is the extremely low capture efficiency for nucleic acids (>10 bases), which severely lowers the sensitivity of an aerolysin-based genetic biosensor. Here we reported a simple and easy-to-operate approach to noncovalently transform aerolysin into a highly nucleic acids-sensitive nanopore. Through a remote pH-modulation mechanism, we simply lower the pH on one side of the pore, then aerolysin is immediately "activated" and enabled to capture target DNA/RNA efficiently from the opposite side of the pore. This mechanism also decelerates DNA translocation, a desired property for sequencing and gene detection, allowing temporal separation of DNAs in different lengths. This method provides insight into the nanopore engineering for biosensing, making aerolysin applicable in genetic and epigenetic detections of long nucleic acids. PMID- 29183113 TI - Comparison between the Bethe-Salpeter Equation and Configuration Interaction Approaches for Solving a Quantum Chemistry Problem: Calculating the Excitation Energy for Finite 1D Hubbard Chains. AB - We calculate the excitation energies of finite 1D Hubbard chains with a variety of different site energies from two perspectives: (i) the physics-based Bethe Salpeter equation (BSE) method and (ii) the chemistry-based configuration interaction (CI) approach. Results obtained from all methods are compared against the exact values for three classes of systems: metallic, impurity-doped, and molecular (semiconducting/insulating) systems. While in a previous study we showed that the GW method holds comparative advantages versus traditional quantum chemistry approaches for calculating the ionization potentials and electron affinities across a large range of Hamiltonians, we show now that the BSE method outperforms CI approaches only for metallic and semiconducting systems. For insulating molecular systems, CI approaches generate better results. PMID- 29183114 TI - DNAzyme-Mediated Assays for Amplified Detection of Nucleic Acids and Proteins.

We continue to use Gp90 exo-, the sole DNA polymerase from Pseudomonas aeruginosa phage PaP1, to study DNA replication upon encountering an abasic site lesion. Gp90 exo- can incorporate dNTPs opposite the abasic site, but extension past this site is extremely slow. Among the four dNTPs, dATP is preferentially incorporated opposite the abasic site, consistent with the A-rule. The incorporation is independent of the identity of the nucleotide 5' of the abasic site. The incorporation of dATP opposite the abasic site occurs by direct incorporation of dNTP opposite the abasic site without a -1 frameshift deletion. Extension from an A:abasic site pair by Gp90 exo- is slightly unfavorable relative to those from other abasic site pairs. Incorporation of dATP opposite the abasic site is preferential and shows a biphasic shape, indicating that this incorporation is much faster than the subsequent dissociation of the polymerase from DNA. The template sequence does not affect the dATP incorporation priority, burst amplitude, burst rate, or dATP dissociation constant. Surface plasmon resonance shows that the presence of an abasic site in the template weakens the binding affinity of Gp90 exo- to DNA in a binary or ternary complex in the presence of any one kind of dNTP. This study reveals that Gp90 exo- preferentially inserts A opposite an abasic site via the A-rule, like other DNA polymerases (e.g., Pol theta, KlenTaq, KF exo-, Pols alpha, delta/PCNA, and Thermococcus litoralis Pol Vent (exo-)), providing further insight into DNA replication mediated by P. aeruginosa phage PaP1 upon encountering an abasic site lesion.

AB - Polymerized ionic liquids (PolyILs) are promising candidates for a wide range of technological applications due to their single ion conductivity and good mechanical properties. Tuning the glass transition temperature (Tg) in these materials constitutes a major strategy to improve room temperature conductivity while controlling their mechanical properties. In this work, we show experimental and simulation results demonstrating that in these materials Tg does not follow a universal scaling behavior with the volume of the structural units Vm (including monomer and counterion). Instead, Tg is significantly influenced by the chain flexibility and polymer dielectric constant. We propose a simplified empirical model that includes the electrostatic interactions and chain flexibility to describe Tg in PolyILs. Our model enables design of new functional PolyILs with the desired Tg.

AB - Accurate analysis of microRNAs (miRNAs) at the single-cell level seriously requires analytical methods possessing extremely high sensitivity, specificity and precision. By rational engineering of a structure-switchable symmetric toehold dumbbell-template (STD-template), we propose a novel isothermal symmetric exponential amplification reaction (SEXPAR) method. The sealed and symmetric structure of the STD-template allows exponential amplification reaction (EXPAR) to occur upon every annealing of target miRNA without loss of amplification efficiency. In addition, the rigid and compact structure of the STD-template with an appropriate standard free energy ensures SEXPAR only be activated by target miRNA. As a result, the SEXPAR method isothermally quantified let-7a down to 0.01 zmol (6.02 copies per 10 MUL) with an ultrahigh specificity which is efficient enough to discriminate one-base-mismatched miRNAs, and a remarkably high precision even for the determination of 6.02 copies let-7a (the standard deviation was reduced from >60% down to 23%). The dynamic range was also extended to 10 orders of magnitude. The method was successfully applied for the determination of let-7a in human tissues, sera and even single-cell lysate, with obviously better precision than quantitative reverse transcription polymerase chain reaction (RT-qPCR) and other EXPAR-based methods. The SEXPAR method may serve as a powerful technique for the biological research and biomedical studies of miRNAs and other short nucleic acids.

AB - The major mononuclear aluminum species obtained in the reaction of aluminum atoms with dimethyl sulfide (DMS) and diethyl sulfide (DES), under cryogenic conditions, are the C-S insertion products, CH3AlSCH3 and CH3CH2AlSCH2CH3, respectively, showing that aluminum atoms can activate C-S bonds. The magnetic parameters were extracted from the EPR spectrum. Support for the spectral assignment was obtained by repeating the experiments with 13C-labeled dimethyl sulfide yielding 13CH3AlS13CH3. DFT calculations using the M06 functional have proven to be effective in predicting the isotropic and anisotropic Al hyperfine interaction values of the aluminum atom C-S insertion products. In addition, the thioalkyl radicals, CH3SCH2* and CH3CH2SCH*CH3 were formed in the aluminum atom reaction. PMID- 29183119 TI - Encoding Microreactors with Droplet Chains in Microfluidics. AB - Droplet-based high throughput biomolecular screening and combinatorial synthesis entail a viable indexing strategy to be developed for the identification of each microreactor. Here, we propose a novel indexing scheme based on the generation of droplet sequences on demand to form unique encoding droplet chains in fluidic networks. These codes are represented by multiunit and multilevel droplets packages, with each code unit possessing several distinct signal levels, potentially allowing large encoding capacity. For proof of concept, we use magnetic nanoparticles as the encoding material and a giant magnetoresistance (GMR) sensor-based active sorting system supplemented with an optical detector to generate and decode the sequence of one exemplar sample droplet reactor and a 4 unit quaternary magnetic code. The indexing capacity offered by 4-unit multilevel codes with this indexing strategy is estimated to exceed 104, which holds great promise for large-scale droplet-based screening and synthesis. PMID- 29183120 TI - Spectroscopic Investigation of the Primary Reaction Intermediates in the Oxidation of Levitated Droplets of Energetic Ionic Liquids. AB - The production of the next generation of hypergolic, ionic-liquid-based fuels requires an understanding of the reaction mechanisms between the ionic liquid and oxidizer. We probed reactions between a levitated droplet of 1-methyl-4-amino 1,2,4-triazolium dicyanamide ([MAT][DCA]), with and without hydrogen-capped boron nanoparticles, and the nitrogen dioxide (NO2) oxidizer. The apparatus exploits an ultrasonic levitator enclosed within a pressure-compatible process chamber equipped with complementary Raman, ultraviolet-visible, and Fourier-transform infrared (FTIR) spectroscopic probes. Vibrational modes were first assigned to the FTIR and Raman spectra of droplets levitated in argon. Spectra were subsequently collected for pure and boron-doped [MAT][DCA] exposed to nitrogen dioxide. By comparison with electronic structure calculations, some of the newly formed modes suggest that the N atom of the NO2 molecule bonds to a terminal N on the dicyanamide anion yielding [O2N-NCNCN]-. This represents the first spectroscopic evidence of a key reaction intermediate in the oxidation of levitated ionic liquid droplets. PMID- 29183121 TI - Comparison of Internal Standard Approaches for SRM Analysis of Alpha-Synuclein in Cerebrospinal Fluid. AB - Absolute protein quantification by selected reaction monitoring (SRM, also MRM) is an alternative to immunoassays, and the gold standard here is the addition of stable-isotope labeled (SIL) proteins (PSAQ). Cerebrospinal fluid (CSF) is the preferred source of biomarkers for neurological diseases, and recent improvements in mass spectrometry enable the quantification of disease-relevant proteins in CSF. We used alpha-synuclein SRM to investigate alternatives to the PSAQ approach in human CSF regarding precision and accuracy, including SIL peptides, winged SIL (WiSIL) peptides, and quantitative protein epitope signature tags (QPrESTs). All approaches yielded precise results in CSF with CV values <15% in several runs for all four measured peptides. PSAQ and QPrEST also showed good accuracy (deviation <=15%), whereas SIL and WiSIL peptides yielded deviations up to 54% that greatly depended on the measured peptide. Total protein concentration in CSF did not affect precision and accuracy. Thus, our study indicates that all four approaches are suitable for relative quantification of alpha-synuclein in CSF. QPrESTs are a valuable alternative to PSAQ in terms of precision and accuracy, although SIL and WiSIL peptides can yield accurate results as well when peptides are selected consciously. PMID- 29183122 TI - Nanoscale Interparticle Distance within Dimers in Solution Measured by Light Scattering. AB - We demonstrate a novel approach to quantify the interparticle distance in colloidal dimers using Mie scattering. The interparticle distance is varied in a controlled way by changing the ionic strength of the solution and the magnetic attraction between the particles. The measured scaling behavior is interpreted using an energy-distance model that includes the repulsive electrostatic and attractive magnetic interactions. The center-to-center distances of particles with a 525 nm radius can be determined with a root-mean-square accuracy of 12 nm. The data show that the center-to-center distance is larger by 83 nm compared to perfect spheres. The underlying distance offset can be attributed to repulsion by charged protrusions caused by particle surface roughness. The measurement method accurately quantifies interparticle distances that can be used to study cluster formation and colloid aggregation in complex systems, e.g., in biosensing applications.

AB - Because of its hyper-leaving ability, as well as its strong oxidizing ability, diaryl(triflato)-lambda3-iodane transfers one of the aryl groups to iodoarenes simply upon gentle heating (>85 degrees C) in nonpolar solvents. We have performed an in-depth mechanistic study of this unusual aryl transfer reaction. A combination of experimental (product analysis, kinetic study, and substituent effects) and density functional theoretical approaches revealed that the reaction proceeds through a concerted bimolecular transition state, in which ipso-carbon binds loosely to both iodine centers. We also evaluated electronic effects on the thermodynamic stability of diaryl-lambda3-iodanes. PMID- 29183125 TI - Quantifying Microsecond Transition Times Using Fluorescence Lifetime Correlation Spectroscopy. AB - Many complex luminescent emitters such as fluorescent proteins exhibit multiple emitting states that result in rapid fluctuations of their excited-state lifetime. Here, we apply fluorescence lifetime correlation spectroscopy (FLCS) to resolve the photophysical state dynamics of the prototypical fluorescence protein enhanced green fluorescent protein (EGFP). We quantify the microsecond transition rates between its two fluorescent states, which have otherwise highly overlapping emission spectra. We relate these transitions to a room-temperature angstrom scale rotational isomerism of an amino acid next to its fluorescent center. With this study, we demonstrate the power of FLCS for studying the rapid transition dynamics of a broad range of light-emitting systems with complex multistate photophysics, which cannot be easily done by other methods. PMID- 29183126 TI - Microfluidic Module for Real-Time Generation of Complex Multimolecule Temporal Concentration Profiles. AB - We designed a microfluidic module that generates complex and dynamic concentration profiles of multiple molecules over a large concentration range using pulse-width modulation (PWM). Our PWM module can combine up to six different inputs and select among three downstream mixing channels, as required by the application. The module can produce concentrations with a dynamic range of three decades. We created complex, temporal concentration profiles of two molecules, with each concentration independently controllable, and show that the PWM module can execute rapid concentration changes as well as long-time scale pharmacokinetic profiles. Concentration profiles were generated for molecules with molecular weights ranging from 560 Da to 150 kDa. Our PWM module produces robust and precise concentration profiles under a variety of operating conditions, making it ideal for integration with existing microfluidic devices for advanced cell and pharmacokinetic studies.

AB - Ten compounds were isolated and identified from green vegetable soya beans, of which five are new triterpenoid saponins (1-5) and five are known compounds (6 10). The chemical structures of the five triterpenoid saponins (1-5) were elucidated to be 3beta,24-dihydroxy-22beta,30-epoxy-30-oxoolean-12-en 3-O-alpha-l rhamnopyranosyl-(1 -> 2)-beta-d-xylopyranosyl-(1 -> 2)-beta-d glucuronopyranoside, 1; 3beta,24-dihydroxy-22beta,30-epoxy-30-oxoolean-12-en 3-O alpha-l-rhamnopyranosyl-(1 -> 2)-beta-d-(3"-O-formyl)-galactopyranosyl-(1 -> 2) beta-d-glucuronopyranoside, 2; 22-keto-3beta,24-dihydroxy oleanane-12-ene 3-O alpha-l-rhamnopyranosyl-(1 -> 2)-beta-d-(3"-O-formyl)-galactopyranosyl-(1 -> 2) beta-d-glucuronopyranoside, 3; 3beta,22beta,24-trihydroxy oxyolean-18(19)-ene-29 acid 3-O-alpha-l-rhamnopyranosyl-(1 -> 2)-beta-d-galactopyranosyl-(1 -> 2)-beta-d glucuronopyranoside, 4; and punicanolic acid 3-O-alpha-l-rhamnopyranosyl-(1 -> 2) beta-d-galactopyranosyl-(1 -> 2)-beta-d-glucuronopyranoside, 5 from the spectroscopic data (IR, GTC/FID, HR-ESI-MS, and 1D and 2D NMR). The nitric oxide release inhibitions of compounds 1-10 in LPS-stimulated RAW264.7 cells were evaluated, and the data suggested that compounds 1, 2, and 5 might possess moderate anti-inflammatory activities, with IC50 values of 18.8, 16.1, and 13.2 MUM, respectively.

PMID- 29183129 TI - Synthesis of 4,5-Diazaspiro[2.3]hexanes and 1,2-Diazaspiro[3.3]heptanes as Hexahydropyridazine Analogues. AB - 4,5-Diazaspiro[2.3]hexanes are made by dihalocarbene addition across the exocyclic double bond of readily accessible 3-alkylidene-1,2-diazetidines. Using difluorocarbene, generated from TMSCF3/NaI, these spirocycles were produced in yields up to 97% by stereospecific addition across the alkene. Lower yields (up to 64%) were observed using more reactive dichlorocarbene, due to competitive insertion of the carbene into the N-N bond. Larger 1,2-diazaspiro[3.3]heptanes are produced by [2 + 2] cycloaddition of 3-alkylidene-1,2-diazetidines with tetracyanoethylene (TCNE) in up to 99% yield. PMID- 29183128 TI - Performance Evaluation of the Q Exactive HF-X for Shotgun Proteomics. AB - Progress in proteomics is mainly driven by advances in mass spectrometric (MS) technologies. Here we benchmarked the performance of the latest MS instrument in the benchtop Orbitrap series, the Q Exactive HF-X, against its predecessor for proteomics applications. A new peak-picking algorithm, a brighter ion source, and optimized ion transfers enable productive MS/MS acquisition above 40 Hz at 7500 resolution. The hardware and software improvements collectively resulted in improved peptide and protein identifications across all comparable conditions, with an increase of up to 50 percent at short LC-MS gradients, yielding identification rates of more than 1000 unique peptides per minute. Alternatively, the Q Exactive HF-X is capable of achieving the same proteome coverage as its predecessor in approximately half the gradient time or at 10-fold lower sample loads. The Q Exactive HF-X also enables rapid phosphoproteomics with routine analysis of more than 5000 phosphopeptides with short single-shot 15 min LC-MS/MS measurements, or 16 700 phosphopeptides quantified across ten conditions in six gradient hours using TMT10-plex and offline peptide fractionation. Finally, exciting perspectives for data-independent acquisition are highlighted with reproducible identification of 55 000 unique peptides covering 5900 proteins in half an hour of MS analysis.

AB - Human papillomavirus (HPV) infection is known to cause anal condyloma acuminatum (CA) and squamous cell carcinoma. Men who have sex with men (MSM) with HIV infection are frequently co-infected with HPV, especially high risk HPV (HR-HPV) that causes anal squamous cell carcinoma. However, there are few reports of HPV genotype studies in anal lesion of Japanese men. We tried to estimate the distribution of HPV genotypes in anal CA tissue specimens from the Japanese men to elucidate the risk of anal cancer. A total of 62 patients who had anal CA surgically excised were enrolled. They included 27 HIV-positive MSM, 18 HIV negative MSM, 1 HIV-positive man who have sex with women (MSW), and 16 HIV negative MSW. HPV genotypes in anal CA tissue were determined by the polymerase chain reaction technique with reverse line blot hybridization. HR-HPV was detected in 45.2% of the CA tissue specimens and high grade squamous intraepithelial lesion (HSIL) was observed in 15.3%. Moreover, the prevalence of HR-HPV in the HIV-positive MSM (70.4%) was higher than the HIV-negative MSM (33.3%, p = .0311) or the HIV-negative MSW (18.8%, p = .0016). The conditional logistic regression analysis suggested HIV positivity as the primary risk factor for the HR-HPV infection in CA. In addition, HSIL was detected in higher frequency in CA tissues from HIV-positive MSM (25.9%) than HIV-negative MSW (0.0%, p = .0346). HR-HPV and HSIL were frequently detected in anal CA tissues from Japanese MSM patients with HIV infection, suggesting the necessity of surveillance for this population. PMID- 29183134 TI - In Vitro Transduction and Target-Mutagenesis Efficiency of HIV-1 pol Gene Targeting ZFN and CRISPR/Cas9 Delivered by Various Plasmids and/or Vectors: Toward an HIV Cure. AB - Efficiency of artificial restriction enzymes toward curing HIV has only been separately examined, using differing delivery vehicles. We compared the in vitro transduction and target-mutagenesis efficiency of consortium plasmid and adenoviral vector delivered HIV-1 pol gene targeting zinc finger nuclease (ZFN) with CRISPR/Cas, Custom-ZFN, CRISPR-Cas-9, and plasmids and vectors (murCTSD_pZFN, pGS-U-gRNA, pCMV-Cas-D01A, Ad5-RGD); cell lines (TZM-bl and ACH 2/J-Lat cells); and the latency reversing agents prostratin, suberoylanilide hydroxamic acid, and phorbol myristate acetate. Cell lines were grown in either Dulbecco's modified Eagle's medium or Roswell Park Memorial Institute with the antibiotics kanamycin, zeocin, and efavirenz. Efficiency was assayed by GFP/luciferase activity and/or validated by yeast MEL1 reporter assay, CEL1 restriction fragment assay, and quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). Ad5-RGD vectors had better transduction efficiency than murCTSD and pGS-U-gRNA/pCMV-Cas-D01A plasmids. CRISPR/Cas9 exhibited better target-mutagenesis efficiency relative to ZFN (delivered by either plasmid or Ad5 vector) based on gel electrophoresis of pol gene amplicons within ACH-2 and J-Lat cells. Ad-5-RGD vectors enhanced target mutagenesis of ZFN, relative to murCTSD_pZFN plasmids, to levels of CRISPR/Cas9 plasmids. Similar reduction of luciferase activity among TZM-bl treated with Ad5-ZFN vectors relative to CRISPR/Cas-9 and murCTSD_pZFN plasmids was observed on challenge with HIV-1. qRT PCR of HIV-1 pol gene transcripts affirmed that Ad5 (RGD) vectors enhanced target mutagenesis of ZFN. Whereas CRISPR/Cas-9 may possess inherent superior target mutagenesis efficiency; the efficiency of ZFN (off-target toxicity withstanding) can be enhanced by altering delivery vehicle from plasmid to Ad5 (RGD) vectors.

AB - Many eukaryotic transcription factors function after forming oligomers. The choice of protein partners is a nonrandom event that has distinct functional consequences for gene regulation. In the present work we examine three dimers of transcription factors in the NFkappaB family: p50p50, p50p65, and p65p65. The NFkappaB dimers bind to a myriad of genomic sites and switch the targeted genes on or off with precision. The p65p50 heterodimer of NFkappaB is the strongest DNA binder, and its unbinding is controlled kinetically by molecular stripping from the DNA induced by IkappaB. In contrast, the homodimeric forms of NFkappaB, p50p50 and p65p65, bind DNA with significantly less affinity, which places the DNA residence of the homodimers under thermodynamic rather than kinetic control. It seems paradoxical that the heterodimer should bind more strongly than either of the symmetric homodimers since DNA is a nearly symmetric target. Using a variety of energy landscape analysis tools, here we uncover the features in the molecular architecture of NFkappaB dimers that are responsible for these drastically different binding free energies. We show that frustration in the heterodimer interface gives the heterodimer greater conformational plasticity, allowing the heterodimer to better accommodate the DNA. We also show how the elastic energy and mechanical strain in NFkappaB dimers can be found by extracting the principal components of the fluctuations in Cartesian coordinates as well as fluctuations in the space of physical contacts, which are sampled via simulations with a predictive energy landscape Hamiltonian. These energetic contributions determine the specific detailed mechanisms of binding and stripping for both homo- and heterodimers.

AB - The laparoscopically administrated adjustable gastric banding used to be widely practiced as treatment of extreme obesity. As lots of complaints and complications arose sooner or later after this procedure, they had to be removed quite often. Half year after such a removal we observed a 37-year-old female patient with complete gastric outlet obstruction. The patient was operated and cured completely. The cause of gastric obstruction was an internal incarceration of the pyloric region between the plication made at the time of the ring removal and the gastric body. We found no similar case of gastric outlet obstruction in the corresponding literature. PMID- 29183136 TI - [Laparoscopic cecal wedge resection]. AB - INTRODUCTION: Several indications of cecal wedge resection can be found in the literature, but the most common ones are acute appendicitis, appendiceal mucocele and selected cecal polyps. PURPOSE: We summarize the indications, review the results of laparoscopic cecal wedge resections carried out in our department from 01.01.2010 till 31.12.2016. A case report is presented when cecal resection was carried out for a cecal polyp. PATIENTS: Between 01.01.2010 and 31.12.2016, 56 patients underwent a laparoscopic cecal wedge resection. The mean age was 42 years (14-83), 28 males and 28 females. In 46 cases, the indication was complicated acute appendicitis, in 6 cases appendiceal mucocele, in the case of four patients endoscopically unresectable benign cecal polyps. RESULTS: The average operating time was 65 minutes. For the procedure we used two 10 mm and one 5 mm port, the resection was performed by using 45 or 60 mm laparoscopic stapler. In 57.1% of the reviewed cases, abdominal drainage was applied. Conversion was necessary in the case of 3 patients (5.4%), once due to bleeding, twice due to technical problems. Surgical complications occured in 4 patients (7.1%), all of them from the complicated appendicitis group: one of grade I by Clavien-Dindo, 3 of grade III. The reoperation rate was 5.4% (3 patients): reoperation was accounted for an abdominal wall phlegmon, a pericecal abscess, and once the suspicion of abdominal abscess which was not verified. Perioperative death did not occur. PMID- 29183137 TI - [Thoracodorsal artery perforator fasciocutaneous flap in the treatment of chronic hidradenitis suppurativa of axilla]. AB - BACKGROUND: The only definitive treatment of chronic axillar hidradenitis suppurativa (HS) that prevents relapses is 'in toto' excision of the infected glandular tissue. This way a deficiency emerges, which needs to be restored. Reconstruction with split skin graft (SSG) is a most common way of recovery, but thoracodorsal artery perforator (TDAP) fasciocutneous flap delivers better functional and aesthetic results. METHOD: Between May 2014 and July 2016, 14 patients underwent reconstructive surgery after excision of axillary HS, 2 of them had bilateral lesion. In 15 cases TDAP was used, in 1 case we used thoracodorsal artery capillar perforator flap (TAPcp). RESULTS: In all but 2 cases 1 dominant perforator was found. 1 flap had 2 dominant perforators and 1 flap was supplied by capillary perforators. Size of the flaps spread between 6 * 8 and 10 * 15 cm. 15 reconstructions were successful, 1 flap necrotised because of the lack of compliance of the patient. CONCLUSION: As a result of the glandular tissue excision carried out because of a chronic HS, a deficiency emerges. TDAP flap is an ideal solution for surgical reconstruction of axillar deficiencies, and a great alternative to SSG. PMID- 29183139 TI - ? PMID- 29183140 TI - ?

The hemodynamic consequences of PT can severely affect the circulation of all tissues, including the microcirculation of the kidneys and the intestinal mucosa. Our aim was to develop a hemodynamically stable and controllable large animal model of PT to study the consequences of cardiogenic shock. METHODS: Two groups of anesthetized vietnamese minipigs (n = 6, both groups) were used. Following laparotomy, a cannula was fixed into the pericardium through the diaphragm without thoracotomy. A sham-operated group served as control, in the second group 60-min PT was induced by intrapericardial injection of heparinised own blood. Throughout PT and 180-min reperfusion, macrohemodynamics, renal circulation and mesenteric macro- and microcirculation were monitored. Myeloperoxidase (MPO) activity was measured and in vivo histology was performed by confocal laser scanning endomicroscopy. RESULTS: The PT increased central venous pressure, heart rate and decreased mean arterial pressure, mesenteric flow (from 355.5 +/- 112.4 vs 182.0 +/- 59.1 ml/min) and renal arterial flow (from 159.63 +/- 50.7 vs 35.902 +/- 27.9 ml/min) and the microcirculation of the ileum. Elevated MPO activity (3.66 +/- 1.6 vs 7.01 +/- 1.44 mU/mg protein) and injury of the ileal mucosa were present also. SUMMARY: The reproducible large animal model is suitable for clinically relevant investigations of the hemodynamic and biochemical consequences of PT. PMID- 29183141 TI - ? PMID- 29183142 TI - ?

AB - INTRODUCTION: Tyrosine kinase inhibitors (TKIs) have transformed the treatment landscape for patients with gastrointestinal stromal tumors (GIST). Unfortunately, resistance to the currently approved TKIs poses a huge challenge, and patients are in need of additional therapeutic options. Fortunately, many novel therapeutic approaches are being tested in treatment of GIST to overcome resistance to the approved TKIs Areas covered: We performed an extensive literature (PUBMED) search to identify emerging drugs being tested in treatment of GIST in early phase clinical trials. We discuss recent ongoing research and emerging novel inhibitors of KIT and PDGFRA receptors, inhibitors in downstream signaling pathways (mTOR and PIK3 inhibitors), inhibitors of other potential targets including ETV1/MEK, MET, FGFR, IGF1R, histone deacetylase inhibitors, heat shock protein 90 inhibitors, cyclin-dependent kinase inhibitors and immune checkpoint inhibitors in treatment of GIST Expert opinion: Multiple agents are under evaluation; those that benefit GIST patients with imatinib resistant mutations, or those with benefit in patients refractory to approved agents are most likely to be developed in this disease. The role of immunotherapy for GIST is still investigational. PMID- 29183146 TI - Improving Rates of Screening for Anemia in Infancy. AB - In 2010, the American Academy of Pediatrics recommended universal screening for anemia at approximately 1 year of age. This quality improvement study sought to improve anemia screening in an ambulatory setting. In a large university-based setting, a best practice alert (BPA) was placed within the electronic health record. The primary outcome was overall screening rate in ambulatory family medicine (DFM) and pediatrics (PEDS) clinics. From 2545 pre-BPA clinic visits over a 12-month period, the screening rate was 48.2%. Among 2186 post-BPA clinic visits over an 8-month period, the screening rate improved to 72.7%, P < .0001. Follow-up over a second 7-month period demonstrated sustained improvements (70.8%) but was not higher after educational sessions between the periods. Screening rates were higher in PEDS than DFM at each time point; P < .0001. This technology-based intervention increased and maintained higher screening rates for anemia at 1 year, with higher rates in PEDS.

AB - In the present study, sulforaphane (SFN)-loaded nanostructured lipid carriers (NLC) were developed and optimized for improved oral efficacy against cancer. The SFN-loaded NLC formulation was developed by melt emulsification ultrasonication technique and optimized by Box-Behnken statistical design. The optimized SFN loaded NLC formulation composed of precirol(r) ATO 5 (solid lipid) and vitamin E (liquid lipid) as lipid phase (3% w/v), poloxamer 188 (1%) and Tween 80 (1%) as surfactant. The mean particle size, polydispersity index, zeta potential, entrapment efficiency (%) and drug loading (%) of optimized SFN-loaded NLC formulation was observed to be 145.38 +/- 4.46 nm, 0.181 +/- 0.023, -25.12 +/- 2.36 mV, 84.94 +/- 3.82% and 14.82 +/- 3.46%, respectively. In vitro drug release studies showed that the release of SFN from optimized NLC formulation was significantly higher (86.52 +/- 5.48%) compared to SFN suspension (38.47 +/- 5.52%) up to 24 h. Ex vivo gut permeation studies revealed a very good enhancement in permeation of drug present in the NLC compared to plain SFN solution and were further confirmed by CLSM. MTT assay in different cancer cell lines showed that the optimized SFN-loaded NLC formulation exhibited significantly improved (p < .05) cytotoxicity compared to free SFN solution. SFN loaded NLC formulation showed significantly improved antioxidant activity compared to free SFN solution. Furthermore, pharmacokinetic study on albino Wistar rats showed 5.04-fold increase in relative oral bioavailability with NLC (p < .05) compared to SFN suspension. Therefore, NLC represents a great potential for improved efficacy of SFN after oral administration.

AB - INTRODUCTION: Efforts on malaria drug discovery are expected to increase in the coming years to achieve malaria eradication. Owing to the increasing number of new potential candidates together with the actual limitations of the primate models, humanized mouse models infected with human Plasmodium spp. (HmHP) now appear as an alternative to the primate model. Areas covered: The authors review the progress obtained in the HmHP in the last two decades, with a special emphasis of their input on the drug discovery pathway. The authors discuss the methodologies and strategies used in these models to obtain an accurate assessment of the compound activity and a reliable prediction of the human efficacious regimen. Expert opinion: Research efforts have led us to an era in which HmHP can successfully be infected with P. falciparum, P vivax and P. ovale. Furthermore, it is now a reality that the complete human cycle of P. falciparum can be obtained in HmHP. The HmHP has shown a real input mainly in the preclinical evaluation of new compounds against the erythrocytic stages of P. falciparum. However, further technical improvements are needed before HmHP may replace the primate model. PMID- 29183149 TI - A Department of Medicine Infrastructure for Patient Safety and Clinical Quality Improvement. AB - Payers, providers, and patients increasingly recognize the importance of quality and safety in health care. Academic Departments of Medicine can advance quality and safety given the large populations they serve and the broad spectrum of diseases they treat. However, there are only few detailed examples of how quality and safety can be organized. This article describes a practical model at The Johns Hopkins Hospital Department of Medicine and details its structure and operation within a large academic health system. It is based on a fractal model that integrates multiple smaller units similar in structure (composition of faculty/staff), process (use of similar tools), and approach (using a common framework to address issues). This organization stresses local, multidisciplinary leadership, facilitates horizontal connections for peer learning, and maintains vertical connections for broader accountability. PMID- 29183150 TI - Effect of Agave americana L. on the human, and Aspergillus oryzae S2 alpha amylase inhibitions. AB - Among phenolic compounds, Agave americana L. extract contained puerarin (38.4%) and p-coumaric acid (12.29%) (pCa). From the Lineweaver-Burk plots, pCa and puerarin demonstrated a competitive and a non competitive inhibitions towards human alpha-amylase activity, respectively. PCa exhibited a higher human inhibitory activity with an IC50 of 98.8 MUM which was about 2.3 times than acarbose. Puerarin (IC50 = 3.87 MUM) and pCa (IC50 = 10.16 MUM) also showed an excellent inhibition for Aspergillus oryzae S2 alpha-amylase activity. The inhibitions of the described biocatalysts compounds towards both amylases were significantly decreased when they were pre-incubated with starch. The binding modes of these compounds were evaluated in silico. The binding efficiency order of these molecules in terms of polar contact numbers for both enzymes was in agreement with the in vitro studies. These findings provided a rational reason to establish the isolated compounds capability as therapeutic target for hyperglycaemia modulation and antifungal therapy. PMID- 29183151 TI - Real-time symptom reporting during elective intracranial pressure monitoring using an interactive handset. AB - BACKGROUND: Determining whether symptoms are related to abnormal intracranial pressure (ICP) may prove challenging in some cases. We evaluated the utility of an in-house designed interactive handset which allows the real-time recording of symptoms during ICP monitoring. METHODS: Adult patients undergoing elective continuous ICP monitoring using the device to investigate symptoms between November 2013 and June 2015 were included in this retrospective observational cohort study. The device allowed the following symptoms to be recorded: mild, moderate and severe headache, visual disturbance and nausea. The corresponding ICP and ICP trend were also recorded. RESULTS: Twenty seven patients underwent 29 episodes of ICP monitoring, reporting 383 symptoms (mild 18%, moderate 39%, severe 20% headaches, visual disturbance 15% and nausea 8%) over a median period of 48 hours (IQR 12). The median number of symptoms reported during each episode was 11 (IQR 11). The mean ICP associated with a symptom episode was 7mmHg (Range 10 to 45). Mild, moderate and severe headache complaints were associated with mean ICPs of 5 (-9 to 26), 6 (-10 to 35) and 14 (-10 to 45) mmHg respectively. The majority of complaints (68%) were reported during instances of normal ICP. Following monitoring, non-operative management was employed on 21 occasions (72%) including valve pressure adjustment on two occasions whilst surgical intervention was required on eight occasions (28%; two surgeries for under-drainage and six for over-drainage). CONCLUSIONS: The device allows the clinician to accurately match a patient's symptoms with ICP to facilitate management decisions. In most instances, symptoms did not closely correlate with an abnormal ICP. By automating and standardising the collection of symptom data, this device may serve as an efficient adjunct when investigating patients with complex hydrocephalus.

AB - Background Acute vascular effects of high intensity physical activity are incompletely characterized. Circulating microparticles are cellular markers for vascular activation and damage. Methods Microparticles were analysed in 99 marathon runners (49 +/- 6 years, 22% female) of the prospective Berlin Beat of Running study. Blood samples were taken within three days before, immediately after and within two days after the marathon run. Endothelial-derived microparticles were labelled with CD144, CD31 and CD62E, platelet-derived microparticles with CD62P and CD42b, leukocyte-derived microparticles with CD45 and monocyte-derived microparticles with CD14. Results Marathon running induced leukocytosis (5.9 +/- 0.1 to 14.8 +/- 0.3 109/l, p < 0.0001) and increased platelet counts (239 +/- 4.6 to 281 +/- 5.9 109/l, p < 0.0001) immediately after the marathon. Blood monocytes increased and lymphocytes decreased after the run ( p < 0.0001). Endothelial-derived microparticles were acutely increased ( p = 0.008) due to a 23% increase of apoptotic endothelial-derived microparticles ( p = 0.007) and returned to baseline within two days after the marathon. Thrombocyte derived microparticles acutely increased by 38% accompanied by an increase in activated and apoptotic thrombocyte-derived microparticles ( p <= 0.0001) each. Both monocyte- and leukocyte-derived microparticles were decreased immediately after marathon run ( p < 0.0001) and remained below baseline until day 2. Troponin T increased from 12 to 32 ng/l ( p < 0.0001) immediately after the run and returned to baseline after two days. Conclusion Circulating apoptotic endothelial- and thrombocyte-derived microparticles increased after marathon running consistent with an acute pro-thrombotic and pro-inflammatory state. Exercise-induced vascular damage reflected by microparticles could indicate potential mechanisms of post-exertional cardiovascular complications. Further studies are warranted to investigate microparticles as markers to identify individuals prone to such complications.

AB - OBJECTIVE: To prepare a new nanosystem of usnic acid (UA) with higher solid content and higher bioavailability. METHODS: Usnic acid nanocrystal suspensions were prepared by the wet milling method, and then the particle size distributions and zeta potential were determined with the Nano ZS90 laser diffraction particle size analyzer. The particles morphology of UA-NCS were observed by scanning electron microscopy method. In addition, solubility and dissolution of UA-NCS in water and phosphate buffer solution were determined in vitro, analyzed by the HPLC method, and then the cellular uptake and pharmacokinetic were carried out on the Caco-2 cells and rats, analyzed by the UPLC-MS/MS method. RESULTS: Particle size distributions and zeta potential of the UA nanocrystal suspension were 268.7 +/- 4.0 nm and -23.1 +/- 0.7 mV, respectively. About the dissolution rate of UA, nanosuspension were significantly faster and higher than common suspension in water and phosphate buffer. And in cellular uptake experiments, the ratio of the maximum amount of drug in unit protein of UA nanosuspension to common suspension was 2.8 times. In rats, oral absorption of nanocrystal UA were superior to the ordinary groups, with the 348% of the maximum concentration and 181% of the AUC after the same dosage administration. CONCLUSION: The wet-milling technique was suitable for the preparation of UA nanocrystal suspension, and a new nanosystem of UA with higher solid content and higher bioavailability was achieved. PMID- 29183155 TI - Arterial stiffness, plasma atherogenic index and soluble cell adhesion molecules in healthy young adults with reduced physical activity. AB - OBJECTIVE: To examine some anthropometric parameters, arterial stiffness, lipid profile, and soluble adhesion molecules in young adults with reduced physical activity. MATERIAL AND METHODS: The study is carried on 54 healthy young adults aged 20.97 +/- 2.04 years. Two groups: 23 with reduced physical activity (INAC) and 31 with optimal physical activity (AC). Body mass index (BMI), basal metabolic rate (BMR), central aortic systolic blood pressure (CSBP, mmHg), plasma atherogenic index (AIP), and serum soluble cell adhesion molecules (sICAM-1, sVCAM-1) are followed up. RESULTS: CSBP [115.56 +/- 10.22 vs. 105.13 +/- 9.88*], AIP [-0.04 +/- 0.18 vs. -0.08 +/- 0.08**] and sICAM-1 [362.5 +/- 49.95 vs. 281.75 +/- 80.39**] are significantly higher, and BMR [1431 +/- 297.9 vs. 1674.6 +/- 365.57*] is significantly lower in the physically inactive young healthy adults. CONCLUSIONS: CSBP, AIP, and sICAM-1 are higher in young adults with reduced physical activity. This plays substantial role in the acceleration of atherogenic process and in long-term perspective could promote cardiovascular diseases. PMID- 29183156 TI - A bioactive new protostane-type triterpenoid from Alisma plantago-aquatica subsp. orientale (Sam.) Sam. AB - A new protostane-type triterpenoid, 5beta,29-dihydroxy alisol A (1) was isolated from Alisma plantago-aquatica subsp. orientale (Sam.) Sam. as well as 12 deoxyphorbol-13alpha-pentadecanoate (2). We first report the presence of compound 2 in the genus Alisma. Their structures were established on the basis of 1D and 2D NMR, and HRESIMS spectroscopic analyses. All the isolated compounds were assayed for their inhibitory effects against human carboxylesterase 2 (HCE-2). Compounds 1 and 2 displayed inhibitory activities against HCE-2 with IC50 values of 29.2 and 4.6 MUM, respectively. The interaction mechanisms of HCE-2 with compounds 1 and 2 were investigated by molecular docking, respectively.

PMID- 29183158 TI - Critical Roles of Glutaredoxin in Brain Cells-Implications for Parkinson's Disease. AB - SIGNIFICANCE: Glutaredoxin (Grx)1, an evolutionarily conserved and ubiquitous enzyme, regulates redox signal transduction and protein redox homeostasis by catalyzing reversible S-glutathionylation. Grx1 plays different roles in different cell types. In Parkinson's disease (PD), Grx1 regulates apoptosis signaling in dopaminergic neurons, so that loss of Grx1 leads to increased cell death; in microglial cells, Grx1 regulates proinflammatory signaling, so that upregulation of Grx1 promotes cytokine production. Here we examine the regulatory roles of Grx1 in PD with a view toward therapeutic innovation. Recent Advances: In postmortem midbrain PD samples, Grx1 was decreased relative to controls, specifically within dopaminergic neurons. In Caenorhabditis elegans models of PD, loss of the Grx1 homologue led to exacerbation of the neurodegenerative phenotype. This effect was partially relieved by overexpression of neuroprotective DJ-1, consistent with regulation of DJ-1 content by Grx1. Increased GLRX copy number in PD patients was associated with earlier PD onset; and Grx1 levels correlated with levels of proinflammatory tumor necrosis factor alpha in mouse and human brain samples. In vitro studies showed Grx1 to be upregulated on proinflammatory activation of microglia. Direct overexpression of Grx1 increased microglial activation; silencing Grx1 diminished activation. Grx1 upregulation in microglia corresponded to increased neuronal cell death in coculture. Overall, these studies identify competing roles of Grx1 in PD etiology. CRITICAL ISSUES: The dilemma regarding Grx1 as a PD therapeutic target is whether to stimulate its upregulation for neuroprotection or inhibit its proinflammatory activity. FUTURE DIRECTIONS: Further investigation is needed to understand the preponderant role of Grx1 regarding dopaminergic neuronal survival. Antioxid. Redox Signal. 00, 000-000. PMID- 29183159 TI - Cytotoxicity of new secondary metabolites, fatty acids and tocols composition of seeds of Ducrosia anethifolia (DC.) Boiss. AB - Two new monoterpene Ducrosin A (1) and sesquiterpene Ducrosin B (2) were isolated along with three known compounds, stigmasterol (3) and two furanocoumarins (4 and 5), from the dichloromethane extract of the seeds of Ducrosia anethifolia (DC.) Boiss. Their structures were determined using extensive 1D and 2D NMR, (ES)-HRMS and IR spectroscopic analyses and by comparison with literature data. Gas chromatography analysis of the fatty acids (FAs) of D. anethifolia seed oils (DAOs) showed high percentages of elaidic acid (C18:1 Delta9t) 65% and oleic acid (C18:1 Delta9c) 15%. The total tocopherol (tocols) content in DAOs was found to be 164 mg/100 g. The cytotoxic effect of the isolates was also evaluated using the MTT assay against the HCT-116 and SKOV-3 cell lines. The results showed that compound 2 was the most cytotoxic agent followed by compounds 1 and 4, which has an epoxide moiety that most likely contributes to its activity. PMID- 29183160 TI - Daily spirometry in an acute exacerbation of adult cystic fibrosis patients. AB - To help answer the question of length of intravenous antibiotics during an acute exacerbation of cystic fibrosis (CF), we had subjects to follow daily home spirometry while on intravenous antibiotics. CF patients, 18 and older, with an acute exacerbation requiring intravenous antibiotics had a daily FEV1. The average time to a 10% increase over their initial sick FEV1 was calculated, as well as the time to a new baseline. A total of 25 subjects completed the study. Ten of the 25 subjects did not have a sustainable 10% increase in FEV1. Of the 15 subjects with a sustainable 10% increase in FEV1, it took 5.2 days (+/-4.5) after day 1, while a new baseline was achieved on average at 6.6 days (+/-4.8) after day 1. Given the wide range of time to a 10% improvement and new baseline, it is recommended there should be flexibility in length of intravenous antibiotics in CF, not by a preset number. PMID- 29183161 TI - Macrophage repolarization using CD44-targeting hyaluronic acid-polylactide nanoparticles containing curcumin. AB - The aim of this study was to evaluate the efficiency of using a natural substance, curcumin, encapsulated in CD44-targeting hyaluronate-polylactide (HA PLA) nanoparticles (NPs) for the modulation of macrophage polarity from the pro inflammatory M1 to anti-inflammatory M2 phenotype. For this purpose, the characterization of the NPs was monitored using 1HNMR, FTIR, DLS and FE-SEM. The effects of curcumin-encapsulated HA-PLA NPs on the viability of LPS/IFN-gamma stimulated peritoneal macrophages were determined using MTT assay. The cellular uptake of free curcumin and nano-formulated curcumin was assessed using confocal microscopy. Also, the expression levels of iNOS-2 (M1 marker), Arg-1 (M2 marker) and also pro-inflammatory cytokines were measured by real-time PCR. Data showed that the nano-formulated curcumin with spherical shape, an average diameter of 102.5 nm and high cellular uptake was significantly less toxic to peritoneal macrophages. Furthermore, the nano-formulated curcumin effectively indicated a reduction in iNOS-2 and an increase in Arg-1 levels than free curcumin. The change in macrophage phenotype by curcumin-encapsulated HA-PLA NPs could suppress the inflammation in LPS/IFN-gamma stimulated macrophages as evidenced by a major reduction in pro-inflammatory cytokines. Conclusively, the results suggested that the curcumin formulation with CD44-targeting HA-PLA NPs might be a promising platform for the treatment of inflammatory diseases. PMID- 29183162 TI - Understanding the DSM-5: stasis and change. AB - This paper aims to understand the DSM-5 through situating it within the context of the historical development of the DSM series. When one looks at the sets of diagnostic criteria, the DSM-5 is strikingly similar to the DSM-IV. I argue that at this level the DSM has become 'locked-in' and difficult to change. At the same time, at the structural, or conceptual, level there have been radical changes, for example in the definition of 'mental disorder', in the role of theory and of values, and in the abandonment of the multiaxial approach to diagnosis. The way that the DSM-5 was constructed means that the overall conceptual framework of the classification only barely constrains the sets of diagnostic criteria it contains. PMID- 29183163 TI - Antimutagenic activity of flavonoids from Sozuku. AB - Pinocembrin (1) and cardamonin (2) from Sozuku showed a suppressive effect on umu gene expression of SOS response in Salmonella typhimurium TA1535/pSK1002 against the mutagen furylfuramide. Compounds 1 and 2 suppressed 52% and 36% of SOS inducing activity at a concentration of 0.20 MUmol/mL. The ID50 value of 1 was 0.18 MUmol/mL. These compounds showed the suppression of 2-amino-3,4 dimethylimidazo-[4,5-f]quinolone (MeIQ) and UV irradiation-induced SOS response. Pinostrobin (3) and 5,7-dimethoxyflavanone (4), methyl ethers of 1, showed similar activity to 1 against MeIQ-induced SOS response, but that of furylfuramide and UV irradiation were decreased. On the other hand, compounds 1-4 did not show the suppression of activated MeIQ-induced SOS response. Furthermore, compounds 1-4 showed potent antimutagenic activity against MeIQ mutagenesis in Ames test using the S. typhimurium TA100 and TA98 strains.

PMID- 29183164 TI - Network meta-analysis of second-line treatment in metastatic renal cell carcinoma: efficacy and safety. AB - This paper aims to compare the approved second-line treatment options in metastatic renal cell carcinoma. A network meta-analysis (NMA) using the frequentist approach and generalized pairwise modeling was computed for the approved drugs in this setting. The results of this NMA showed that the combination of lenvatinib and everolimus yielded the lowest hazard ratio (HR) for progression-free survival (HR: 0.4; 95% CI: 0.21-0.75) and overall survival (HR: 0.55; 95% CI: 0.30-1.00). The great efficacy of this combination is limited by the prevalence of grade 3-4 adverse events (70.6%) leading to treatment discontinuation in 17.6%. This NMA is to the best of our knowledge, the first analysis of the approved regimens for the second-line treatment of metastatic renal cell carcinoma. PMID- 29183166 TI - Use of extrusion aids for successful production of Kollidon(r) CL-SF pellets by extrusion-spheronization. AB - OBJECTIVE: Fine particle ethylcellulose (FPEC) or poly(ethylene oxide) (PEO) addition to a Kollidon CL-SF was investigated to address low yield and poor sphericity in extruded-spheronized pellets. SIGNIFICANCE: The success of crospovidone as a diluent in extrusion-spheronization was dependent on a small particle size of the polymer. FPEC aided production of rugged and spherical pellets using a large particle size grade, Polyplasdone(r) XL. PEO acted as an extrusion-spheronization aid when ethylcellulose was the diluent. These extrusion spheronization aids could serve in this role when Kollidon(r) CL-SF (K CL-SF) is the diluent. METHODS: The influence of formulation and process variables on pellet properties was investigated using design of experiments. A planetary mixer was used to prepare powder blends and the wetted mass after addition of water. An EXD 60 extruder produced extrudate that was spheronized in a Q230 marumerizer. Wet pellets were dried in a forced-air oven. RESULTS: FPEC improved rounding up but reduced pellet yield. Poly(ethylene oxide) imparted desired characteristics to the wetted mass, the extrudate, and the spheronized pellets. Pellet average diameter, yield, sphericity, aspect ratio, friability, and dissolution profile were assessed. Equations for pellet characteristics facilitated discussion of the influences of factors and their interactions. Optimization was performed on pellets that included PEO. CONCLUSIONS: PEO proved to be an exceptional extrusion spheronization aid in the preparation of pellets using K CL-SF. It facilitated wetted mass extrusion with minimal mass loss to the extruder, and markedly improved the sphericity of the pellets produced by marumerization. Immediate release pellets were obtained. PMID- 29183167 TI - Adding Pertuzumab to Trastuzumab and Taxanes in HER2 positive breast cancer. AB - INTRODUCTION: The monoclonal antibody trastuzumab has improved the median disease free and overall survival of patients with early stage breast cancer that overexpresses the human epidermal growth factor receptor 2 (HER2). Despite this advance, some patients experience cancer relapse and novel approaches are always needed. One such advance is the monoclonal antibody pertuzumab, which prevents dimerisation between members of the HER family of transmembrane glycoprotein receptors. Areas covered: In this review, the authors analyse recent research which has focused on the development of new HER2 targeting agents for HER2 positive breast cancer, particularly pertuzumab, and its addition to trastuzumab and taxanes. Expert opinion: Pertuzumab has significantly improved disease control in patients with advanced HER2 positive breast cancer when added to chemotherapy and trastuzumab. Although pertuzumab has also increased response rates in the preoperative setting, this has not yet translated into increased overall survival. The authors believe that future research should focus on improvements in novel biomarkers to select patients for new treatments. PMID- 29183168 TI - Minimal Custom Pack Design and Wide-Awake Hand Surgery: Reducing Waste and Spending in the Orthopedic Operating Room. AB - BACKGROUND: The US health care sector has substantial financial and environmental footprints. As literature continues to study the differences between wide-awake hand surgery (WAHS) and the more traditional hand surgery with sedation & local anesthesia, we sought to explore the opportunities to enhance the sustainability of WAHS through analysis of the respective costs and waste generation of the 2 techniques. METHODS: We created a "minimal" custom pack of disposable surgical supplies expressly for small hand surgery procedures and then measured the waste from 178 small hand surgeries performed using either the "minimal pack" or the "standard pack," depending on physician pack choice. Patients were also asked to complete a postoperative survey on their experience. Data were analyzed using 1- and 2-way ANOVAs, 2-sample t tests, and Fisher exact tests. RESULTS: As expected, WAHS with the minimal pack produced 0.3 kg (13%) less waste and cost $125 (55%) less in supplies per case than sedation & local with the standard pack. Pack size was found to be the driving factor in waste generation. Patients who underwent WAHS reported slightly greater pain and anxiety levels during their surgery, but also reported greater satisfaction with their anesthetic choice, which could be tied to the enthusiasm of the physician performing WAHS. CONCLUSIONS: Surgical waste and spending can be reduced by minimizing the materials brought into the operating room in disposable packs. WAHS, as a nascent technique, may provide an opportunity to drive sustainability by paring back what is considered necessary in these packs. Moreover, despite some initial anxiety, many patients report greater satisfaction with WAHS. All told, our study suggests a potentially broader role for WAHS, with its concomitant emphases on patient satisfaction and the efficient use of time and resources. PMID- 29183169 TI - United States Registered Nurse Workforce Report Card and Shortage Forecast: A Revisit. AB - This is a reevaluation of registered nurse (RN) supply and demand from 2016 to 2030 using a previously published work forecast model and grading methodology with more recent workforce data. There will be a shortage of 154 018 RNs by 2020 and 510 394 RNs by 2030; the South and West regions will have higher shortage ratios than Northeast and Midwest regions. This reflects a nearly 50% overall improvement when compared with the authors' prior study, and the low-performing states have improved from 18 "D" and 12 "F" grades as published earlier to 13 "D" and 1 "F" in this study. Although progress has been made, efforts to foster the pipelines for improving the nursing workforce need to be continued. PMID- 29183171 TI - Attaining cholesterol goals: will aiming for lower targets improve the score? PMID- 29183170 TI - Primary central nervous system lymphoma and glioblastoma differentiation based on conventional magnetic resonance imaging by high-throughput SIFT features. AB - PURPOSE OF THE STUDY: Due to the totally different therapeutic regimens needed for primary central nervous system lymphoma (PCNSL) and glioblastoma (GBM), accurate differentiation of the two diseases by noninvasive imaging techniques is important for clinical decision-making. MATERIALS AND METHODS: Thirty cases of PCNSL and 66 cases of GBM with conventional T1-contrast magnetic resonance imaging (MRI) were analyzed in this study. Convolutional neural networks was used to segment tumor automatically. A modified scale invariant feature transform (SIFT) method was utilized to extract three-dimensional local voxel arrangement information from segmented tumors. Fisher vector was proposed to normalize the dimension of SIFT features. An improved genetic algorithm (GA) was used to extract SIFT features with PCNSL and GBM discrimination ability. The data-set was divided into a cross-validation cohort and an independent validation cohort by the ratio of 2:1. Support vector machine with the leave-one-out cross-validation based on 20 cases of PCNSL and 44 cases of GBM was employed to build and validate the differentiation model. RESULTS: Among 16,384 high-throughput features, 1356 features show significant differences between PCNSL and GBM with p < 0.05 and 420 features with p < 0.001. A total of 496 features were finally chosen by improved GA algorithm. The proposed method produces PCNSL vs. GBM differentiation with an area under the curve (AUC) curve of 99.1% (98.2%), accuracy 95.3% (90.6%), sensitivity 85.0% (80.0%) and specificity 100% (95.5%) on the cross-validation cohort (and independent validation cohort). CONCLUSIONS: Since the local voxel arrangement characterization provided by SIFT features, proposed method produced more competitive PCNSL and GBM differentiation performance by using conventional MRI than methods based on advanced MRI. PMID- 29183172 TI - Endoscopic submucosal dissection of gastric neoplasms using a snare tip. AB - BACKGROUND: Endoscopic submucosal dissection (ESD) enables the complete removal of gastric lesions regardless of tumor size. ESD is typically performed using one of several available electrocautery knives and endoscopic mucosal resection (EMR) is performed using a diathermic snare. We aimed to investigate the clinical outcomes and complications in patients in whom a snare tip was used for ESD. MATERIALS AND METHODS: We retrospectively evaluated the medical records of 30 patients who underwent removal of a gastric lesion using a snare tip by ESD or hybrid ESD (ESD with snaring). For hybrid ESD, snaring was performed after an adequate submucosal dissection. The clinical outcomes according to the endoscopic procedure performed were evaluated. RESULTS: ESD was performed in 12 patients and hybrid ESD was performed in 26 patients. Overall en-bloc and complete resection rates were both 97.4%. There was one case where piece-meal resection was performed in the hybrid ESD group. There were no procedure related complications such as perforation or bleeding. The mean specimen size was 2.8 +/- 0.6 cm in the ESD group and 2.3 +/- 0.5 cm in the hybrid ESD group (p = .031). The mean procedure time did not differ between the two methods (12.8 min in ESD and 9.7 min in hybrid ESD, p = .060). CONCLUSIONS: The snare tip can be used as an electrocautery knife to incise the mucosa and dissect the submucosa during removal of a gastric lesion. PMID- 29183173 TI - Evaluation for shunted pouches of cavernous sinus dural arteriovenous fistula and the treatment outcome of transvenous embolization. AB - Background This study aimed to evaluate the detailed location and the number (single or multiple) of cavernous sinus dural arteriovenous fistula (CSDAVF) shunted pouches as well as the relationship between the characteristics of shunted pouch(es) and the treatment outcome of transvenous embolization for CSDAVF. Methods A total of 23 consecutive patients with CSDAVFs who underwent angiogram and transvenous embolization were retrospectively analyzed. Shunted pouches were assessed using three-dimensional angiogram and multiplanar reformatted image obtained from the rotational angiogram data. Results Of the 23 patients with CSDAVFs, 40 shunted pouches were identified. Twelve CSDAVFs had a single shunted pouch, and 11 had multiple shunted pouches. The mean CSDAVF with multiple shunted pouches was 2.5. The shunted pouches were more often found in the posterior compartment of the CS, which was connected with the intercavernous sinus (23/40; 57.5%). In 12 CSDAVFs with a single shunted pouch, 10 were treated with selective embolization and complete occlusion was achieved during the follow up. Two CSDAVFs with single shunted pouch were just observed without intervention, and DAVFs disappeared spontaneously during the follow-up period. In 11 CSDAVFs with multiple shunted pouches, eight were treated with selective embolization and three with sinus embolization. In six of eight (75%), complete occlusion was achieved following selective embolization, but two of eight (25%) recurred and required retreatment. Conclusions Rotational angiography data suggested that the shunted pouches of CSDAVFs were mostly located in the posterior compartment of the CS connected with the intercavernous sinus. Selective embolization for CSDAVFs with a single shunted pouch is the first-line treatment alternative to sinus packing, and selective embolization with multiple shunted pouches will be a considerable treatment option. PMID- 29183174 TI - Limit of intraoperative near-infrared spectroscopy monitoring during endovascular thrombectomy in acute ischemic stroke. AB - Endovascular thrombectomy is recommended for a persistent ischemic penumbra if recanalization cannot be achieved by the intravenous (IV) administration of recombinant tissue-plasminogen activator (rt-PA) alone. Although endovascular thrombectomy is a powerful treatment for major cerebral artery occlusion, the monitoring of recanalization and reperfusion during acute ischemic stroke presents a therapeutic challenge, and a previous study reported the usefulness of near-infrared spectroscopy (NIRS) for intraoperative monitoring during emergency endovascular thrombectomy for acute large ischemic stroke. Here we present our experience with a relevant case series. We applied NIRS monitoring during endovascular thrombectomy in two patients with large ischemic stroke following carotid artery occlusion and one patient with a non-large ischemic stroke caused by a distal middle cerebral artery (MCA) occlusion. In the patients with large ischemic stroke, complete recanalization of the internal carotid artery was achieved, and NIRS revealed a very good regional oxygen saturation (rSO2) response. By contrast, in the patient with non-large ischemic stroke, the rSO2 did not change, despite complete recanalization of the distal MCA. Our findings suggest the limited usefulness of intraoperative NIRS monitoring during emergency endovascular thrombectomy for non-large acute ischemic stroke caused by a distal MCA occlusion. However, intraoperative NIRS monitoring could be used practically to detect recanalization of the major artery during thrombectomy and early IV rt PA administration in cases involving major artery occlusion.

AB - INTRODUCTION: There is little specific guidance on the implementation of cost effectiveness modelling at the early stage of test development. The aim of this study was to review the literature in this field to examine the methodologies and tools that have been employed to date. Areas Covered: A systematic review to identify relevant studies in established literature databases. Five studies were identified and included for narrative synthesis. These studies revealed that there is no consistent approach in this growing field. The perspective of patients and the potential for value of information (VOI) to provide information on the value of future research is often overlooked. Test accuracy is an essential consideration, with most studies having described and included all possible test results in their analysis, and conducted extensive sensitivity analyses on important parameters. Headroom analysis was considered in some instances but at the early development stage (not the concept stage). Expert commentary: The techniques available to modellers that can demonstrate the value of conducting further research and product development (i.e. VOI analysis, headroom analysis) should be better utilized. There is the need for concerted efforts to develop rigorous methodology in this growing field to maximize the value and quality of such analysis. PMID- 29183176 TI - Incidence of maternal tachycardia during the second stage of labor: a prospective observational cohort study. AB - OBJECTIVE: To our knowledge, this is the largest prospective study reporting on maternal heart rate (MHR) levels in laboring women (30 patients), and maternal tachycardia that is a potential risk factor in fetal monitoring confusion. Our objective was to analyze a large population of contiguous laboring patients and to assess the MHR levels attained during the second stage. METHODS: We performed a prospective study that analyzed MHR levels of second-stage laboring patients evaluating numerous predisposing maternal conditions. Univariate and stepwise multivariate logistic regression analysis were performed. RESULTS: A total of 1105 contiguous patients were analyzed and 33.9% had a sustained MHR >=100; 18.8% had an MHR >=110; and 9.1% had an MHR >=120. Multivariate analysis of all potential predisposing maternal conditions did not reveal any specific variable as uniformly significant for predicting maternal tachycardia across all levels of analysis. CONCLUSIONS: The incidence of maternal tachycardia in the second stage of labor is common. We recommend that if the MHR is >=100 during labor, the simultaneous maternal and fetal heart rate (FHR) monitoring will be used to minimize the potential for fetal monitoring confusion and risking poor fetal outcome if the fetus is in distress.

AB - INTRODUCTION: Low Apgar scores (<7) measured at age 5 minutes can predict short term infant morbidity and mortality. Although an association exists between low Apgar scores and neuropsychological disorders, other childhood disorders were not thoroughly studied. We aimed to study the possible association between low 5 minute Apgar scores in term newborns and their long-term childhood gastrointestinal (GI) morbidity. METHODS: A population-based cohort analysis was performed comparing total and different subtypes of GI-related pediatric hospitalizations among newborns with normal (>=7) and low (<7) 5-minute Apgar scores. The analysis included all term singletons born between the years 1999 and 2014 at a single tertiary regional medical center. Infants with congenital malformations, multiple gestations, and all perinatal deaths were excluded from the analysis. GI-related morbidities included hospitalizations involving a predefined set of ICD-9 codes, as recorded in the hospital computerized files. A Kaplan-Meier survival curve was constructed to compare the cumulative GI morbidity, and a Cox proportional hazards model was used to adjust for confounders. RESULTS: The study population, including 223 244 term singletons, was followed for an average of 10.02 +/- 6.0 years (0-18 years, median 10.25) following discharge from birth hospitalization. Low 5-minute Apgar scores were recorded in 585 (0.3%) newborns. Incidence of GI-related hospitalizations was higher among the low versus the normal 5-minute Apgar score group (7.4 versus 5.2%; 8.6/1000 person years (PY) versus 5.2/1000 PY, respectively; p = .02; odds ratio =1.66, 95%CI 1.36-1.96). The association remained significant and independent while adjusting for gestational age, fetal weight, offspring gender, maternal age, maternal smoking, hypertension, and diabetes (Adjusted HR =1.57, 95%CI 1.16-2.12, p = .003). CONCLUSIONS: Low 5 minutes Apgar score is associated with an increased risk for long-term pediatric GI morbidity of the offspring. Our results suggest that Apgar scores can be used as a possible predictor for long term pediatric morbidities and thus may necessitate appropriate surveillance in this vulnerable group of children. PMID- 29183178 TI - Health providers' communication skills training affects hypertension outcomes. AB - OBJECTIVE: Hypertension is a common cardiovascular risk factor within the Iranian population, and this may be improved through changes in lifestyle. We aimed at improving hypertension outcomes and health literacy skills among hypertensive patients through communication skills training targeting health providers. METHODS: A randomized controlled trial method was used to enroll 35 health providers and 240 hypertensive patients attending community-based healthcare practices in the Mashhad, Iran. We evaluated the effects of a communication skills intervention for primary care providers compared to usual care controls, on the hypertension outcomes, patient medication adherence, and self-efficacy, assessed at baseline and post-intervention. Bivariate analysis and the regression model were used to assess whether the health provider training improved outcomes. RESULTS: Majority of participating patients were female (77.3%), less than high school education (80.3%), married (82.3%), and low income (82.3%), with mean age of 37 years. Following the educational intervention, there was a significant improvement (p < 0.05) in patient communication skills, self-efficacy, adherence to medication, and hypertension outcomes in the intervention compared to the control group. CONCLUSIONS: The brief communication skills training for health care providers appear to be an efficient way to improve patient-provider communication skills and hypertension outcome among patients with uncontrolled BP.

AB - INTRODUCTION: With increasing focus on nutritional strategies to counter the rising global burden of allergic disease, there has been a particular focus on prebiotic nutrients that are selectively utilized by host microorganisms to confer potential immunomodulatory benefits for disease prevention. Areas covered: In this review we examine maternal and infant dietary sources of prebiotics with a particular focus on non-digestible oligosaccharides, which undergo microbial fermentation by commensal gut bacteria to produce short chain fatty acids (SCFA). We summarize the major proposed health benefits of SCFA in early life immune development, together with the current evidence for maternal and/or infant prebiotic consumption in abrogating the risk of early childhood allergic diseases. Medline searches (to August 2017) for English language papers included prebiotics and SCFA search terms in combination with relevant allergic disease terms. Expert commentary: The potential beneficial effects of maternal and infant prebiotic consumption for allergy prevention are promising, but still require considerably further investigation through high-quality randomised controlled trials and detailed mechanistic studies. This should be coupled with more research on the biological effects of human milk oligosaccharides (HMO), including their influence on infant immune development, and the maternal nutritional factors that optimise HMO composition and infant outcomes. PMID- 29183180 TI - A spotlight on the management of complications associated with myeloproliferative neoplasms: a clinician's perspective. AB - INTRODUCTION: Myeloproliferative neoplasms (MPNs) are associated with a variety of symptoms and signs which cause major morbidity for the patients. The disorders are associated with increased incidence of thromboembolic and hemorrhagic events which can lead to complications and shortened life expectancy. Areas covered: Using systematic literature review and expert clinical and research experience the authors discuss strategies for the management of symptoms and signs including pruritus, fatigue, splenomegaly, and cytopenia. Cytoreduction including treatments to inhibit the JAK/STAT pathway are considered. Pathogenesis and prevention and treatment of thrombotic and hemorrhagic events and their management is addressed and the suggested management of the special situations such as surgery and pregnancy are discussed. Expert commentary: Management of disease has traditionally focused on symptom treatment and complication prevention but the discovery of driver mutations has led to treatments aiming to eliminate the clone, which should be the ultimate goal of therapy. A future challenge is to develop safe and effective MPN therapy and to personalize therapy. PMID- 29183181 TI - Maternal anemia during pregnancy and small for gestational age: a systematic review and meta-analysis. AB - OBJECTIVE: Anemia is a major public health and nutritional problem in the world. Studies have reported the relationship between anemia during pregnancy and small for gestational age (SGA). Therefore, the present systematic review and meta analysis was conducted to determine the relationship between maternal anemia during pregnancy and SGA. METHOD: This meta-analysis was conducted without time limit until April 2017 based on the PRISMA protocol. Several international databases including Cochrane, Scopus, Web of Science (ISI), Pubmed, Embase, and Google Scholar search engine were searched independently by two researchers. The keywords include: anemia, pregnant women, gestational age, and pregnancy. The relative risk (RR) and 95% confidence interval were estimated regarding to the significance of the I2 index based on the random effects model. Data were analyzed using Comprehensive Meta-Analysis Software version 2. RESULTS: Ten studies with a sample size including 620 080 pregnant women entered the meta analysis process. The overall relationship between maternal anemia during pregnancy and SGA was not significant (RR = 1.11 [95%CI: 0.99-1.24, p = .074]). The relationship between anemia during pregnancy and SGA based on pregnancy trimester showed that maternal anemia was significant in the first trimester, (RR = 1.11 [95%CI: 1-1.22, p = .044]), but this relationship was not significant in the second trimester (RR = 1.11 [95%CI: 0.85-1.18, p = .91]). CONCLUSIONS: Maternal anemia in the first trimester of pregnancy can be considered as a risk factor for negative pregnancy outcomes (SGA). PMID- 29183182 TI - Cost effectiveness of human papilloma virus vaccination in low and middle income countries: a systematic review of literature. AB - INTRODUCTION: Low and middle income countries (LMICs) bear more than 50% of the current cervical cancer burden over the last decade with linkages to lack of HPV vaccination, high levels of poverty, illiteracy and nonexistent or poor screening programs. Governments of LMICs need enough convincing evidence that HPV vaccination will be more cost-effective in reducing the scourge of cervical cancer. Area covered: A systematic review to identify suitable studies from MEDLINE(via PubMed), EMBASE and Electronic search through GOOGLE for original and review articles from 2007 to 2014 on cost-effectiveness of human papilloma virus vaccination of pre-adolescent girls in LMICs was conducted. A total of 19 full articles were finally selected and reviewed after screening out those not consistent with the inclusion and exclusion criteria. Expert commentary: Most studies on cost-effectiveness of HPV vaccine in LMICs show that lowering cost of HPV vaccination with or without Pap smear screening is cost-effective in areas with high incidence of cervical cancer. PMID- 29183183 TI - Peer group reflection on student ratings stimulates clinical teachers to generate plans to improve their teaching. AB - BACKGROUND: Previous studies have demonstrated that student ratings of a teachers' performance do not incentivize clinical teachers to reflect critically and generate plans to improve their teaching. Peer group reflection might offer a solution in mediating this change. AIM: To investigate: (a) to which extent clinical teachers perceive self-evaluation, student ratings and peer group reflection effective; and (b) whether additional peer group reflection fosters critical reflection and the translation of feedback into concrete plans of action. METHOD: We conducted a quasi-experiment, inviting two groups of 10 clinical teachers each (1) to complete a self-evaluation and (2) subsequently examine their student ratings. One group participated in (3) an additional peer group reflection meeting. All participants were finally requested to define plans for improvement and evaluate each activity's effectiveness. RESULTS: Participants perceived all three activities to be effective. Levels of reflection did not differ across the two groups. However, participation in peer group reflection did result in generating more concrete plans to change clinical teaching. CONCLUSIONS: Peer group reflection on student ratings shows promise as tool to assist clinical teachers in generating plans for improvement. Future research should focus on whether teaching indeed improves with the introduction of peer group reflection. PMID- 29183184 TI - Third trimester ultrasound for fetal macrosomia: optimal timing and institutional specific accuracy. AB - PURPOSE: To determine the performance of third trimester ultrasound in women with suspected fetal macrosomia. MATERIALS AND METHODS: We performed a retrospective cohort study of fetal ultrasounds from January 2004 to December 2014 with estimated fetal weight (EFW) between 4000 and 5000 g. We determined accuracy of birth weight prediction for ultrasound performed at less than and greater than 38 weeks, accounting for diabetic status and time between ultrasound and delivery. RESULTS: There were 405 ultrasounds evaluated. One hundred and twelve (27.7%) were performed at less than 38 weeks, 293 (72.3%) at greater than 38 weeks, and 91 (22.5%) were performed in diabetics. Sonographic identification of EFW over 4000 g at less than 38 weeks was associated with higher correlation between EFW and birth weight than ultrasound performed after 38 weeks (71.5 versus 259.4 g, p < .024). EFW to birth weight correlation was within 1.7% of birth weight for ultrasound performed less than 38 weeks and within 6.5% of birth weight for ultrasound performed at greater than 38 weeks. CONCLUSIONS: Identification of EFW with ultrasound performed less than 38 weeks has greater reliability of predicting fetal macrosomia at birth than measurements performed later in gestation. EFW to birth weight correlation was more accurate than previous reports. PMID- 29183185 TI - The effect of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry instrumentation parameters on the matrix-assisted laser desorption/ionization simulated size exclusion chromatography number-mass, average-weight and polydispersity values of dextran against corresponding values obtained by size exclusion chromatography. AB - The matrix-assisted laser desorption/ionization simulated size exclusion chromatography (SECPC) average-number mass, weight average and polydispersity of dextran 1000 were determined by matrix-assisted laser desorption/ionization (MALDI) time-of-flight (TOF) mass spectrometry. The instrument parameters were varied and the SECPC value determined via the Bruker XMASS software was compared to the value obtained from aqueous-phase size exclusion chromatography. The aqueous-phase size exclusion chromatography values for average-number mass, weight average and polydispersity were 1223 Da, 1500 Da and 1.23 (1010 Da, 1270 Da and 1.26 from manufacturer), whereas the SECPC value varied on the instrumental parameters. The factors that had the greatest effect on the average number mass, weight average and polydispersity were: (most effect on SECPC value) laser attenuation > matrix-analyte molar concentration > matrix-analyte molar ratios > delay extraction time > solvent-system composition > detector delay (least effect on SECPC value). The oligosaccharide signal distribution as a function of laser attenuation indicate that two distinct regions exist in dextran 1000, where one corresponds to the higher mass oligosaccharides (hexasaccharide or greater), while another region corresponds to lower oligosaccharides (tetra saccharide). This distribution depends upon the crystallization of the biopolymer and the efficiency of desorption/ionization, which yields the SECPC value. There was broad agreement between the SECPC values and size exclusion chromatography values for dextran, although the polydispersity indicated by SECPC was less than size exclusion chromatography (1.10 vs. 1.26). It can be shown that for narrow polydisperse biopolymers the instrumental conditions are less critical in the determination of average-number mass, weight average and polydispersity, although the SECPC Mn, and weight average values are often higher than the corresponding values obtained by aqueous-phase size exclusion chromatography. PMID- 29183186 TI - A new approach for accurate mass assignment on a multi-turn time-of-flight mass spectrometer. AB - A simple, effective accurate mass assignment procedure for a time-of-flight mass spectrometer is desirable. External mass calibration using a mass calibration standard together with an internal mass reference (lock mass) is a common technique for mass assignment, however, using polynomial fitting can result in mass-dependent errors. By using the multi-turn time-of-flight mass spectrometer infiTOF-UHV, we were able to obtain multiple time-of-flight data from an ion monitored under several different numbers of laps that was then used to calculate a mass calibration equation. We have developed a data acquisition system that simultaneously monitors spectra at several different lap conditions with on-the fly centroid determination and scan law estimation, which is a function of acceleration voltage, flight path, and instrumental time delay. Less than 0.9 mDa mass errors were observed for assigned mass to charge ratios ( m/z) ranging between 4 and 134 using only 40Ar+ as a reference. It was also observed that estimating the scan law on-the-fly provides excellent mass drift compensation. PMID- 29183187 TI - Peter J Derrick and the Grand Scale 'Magnificent Mass Machine' mass spectrometer at Warwick. AB - The value of the Grand Scale 'Magnificent Mass Machine' mass spectrometer in investigating the reactivity of ions in the gas phase is illustrated by a brief analysis of previously unpublished work on metastable ionised n-pentyl methyl ether, which loses predominantly methanol and an ethyl radical, with very minor contributions for elimination of ethane and water. Expulsion of an ethyl radical is interpreted in terms of isomerisation to ionised 3-pentyl methyl ether, via distonic ions and, possibly, an ion-neutral complex comprising ionised ethylcyclopropane and methanol. This explanation is consistent with the closely similar behaviour of the labelled analogues, C3H7CH2CD2OCH3+. and C3H7CD2CH2OCH3+., and is supported by the greater kinetic energy release associated with loss of ethane from ionised n-propyl methyl ether compared to that starting from directly generated ionised 3-pentyl methyl ether. PMID- 29183189 TI - Editor's personal foreword. PMID- 29183188 TI - Prof. Peter J Derrick (1945-2017). PMID- 29183190 TI - Basic poly(propylene glycols) as reference compounds for internal mass calibration in positive-ion matrix-assisted laser desorption/ionization mass spectrometry. AB - Basic poly(propylene glycols), commercially available under the trade name Jeffamine, are evaluated for their potential use as internal mass calibrants in matrix-assisted laser desorption/ionization-time-of-flight-mass spectrometry. Due to their basic amino endgroups Jeffamines are expected to deliver [M+H]+ ions in higher yields than neutral poly(propylene glycols) or poly(ethylene glycols). Aiming at accurate mass measurements and molecular formula determinations by matrix-assisted laser desorption/ionization-time-of-flight-mass spectrometry, four Jeffamines (M-600, M-2005, D-400, D-230) were thus compared. As a result, Jeffamine M-2005 is introduced as a new mass calibrant for positive-ion matrix assisted laser desorption/ionization-time-of-flight-mass spectrometry in the range of m/z 200-1200 and the reference mass list is provided. While Jeffamine M 2005 is compatible with alpha-cyano-4-hydroxycinnamic acid, 2,5-dihydroxybenzoic acid, and 2-[(2 E)-3-(4- tert-butylphenyl)-2-methylprop-2-enylidene]malonitrile matrix, its use in combination with 2-[(2 E)-3-(4- tert-butylphenyl)-2-methylprop 2-enylidene]malonitrile provides best results due to low laser fluence requirements. Applications to PEG 300, PEG 600, the ionic liquid trihexyl(tetradecyl)-phosphonium tris(pentafluoroethyl)-trifluorophosphate, and [60]fullerene demonstrate mass accuracies of 2-5 ppm. PMID- 29183191 TI - Mechanisms governing the fragmentation of glycerophospholipids containing choline and ethanolamine polar head groups. AB - Glycerophospholipids are the major amphiphilic molecules found in the plasma membrane bilayer of all vertebrate cells. Involved in many biological processes, their huge structural diversity and large concentration scale make their thorough characterization extremely difficult in complex biological matrices. Mass spectrometry techniques are now recognized as being among the most powerful methods for the sensitive and comprehensive characterization of lipids. Depending on the experimental conditions used during electrospray ionization mass spectrometry experiments, glycerophospholipids can be detected as different molecular species (e.g. protonated, sodiated species) when analyzed either in positive or negative ionization modes or by direct introduction or hyphenated mass spectrometry-based methods. The observed ionized forms are characteristic of the corresponding phospholipid structures, and their formation is highly influenced by the polar head group. Although the fragmentation behavior of each phospholipid class has already been widely studied under low collision energy, there are no established rules based on charge-induced dissociation mechanisms for explaining the generation of fragment ions. In the present paper, we emphasize the crucial roles played by ion-dipole complexes and salt bridges within charge-induced dissociation processes. Under these conditions, we were able to readily explain almost all the fragment ions obtained under low-energy collision-induced dissociation for particular glycerophospholipids and lysoglycerophospholipids species including glycerophosphatidylcholines and glycerophosphatidylethanolamines. Thus, in addition to providing a basis for a better comprehension of phospholipid fragmentation processes, our work also highlighted some potentially new relevant diagnostic ions to signal the presence of particular lipid species. PMID- 29183192 TI - Proton-induced reactions of [2.2]-paracyclophane in the gas phase. A study by FT ICR-spectrometry and DFT calculation. AB - The reactions of the [2-2]-paracyclophane 1 and the [2-2]-metaparacyclopane 2 in the gas phase after protonation by CI(CH4) or CI(I-C4H10) were studied by FT-ICR mass spectrometry. The ions C16H17+ produced in the external ion source of the FT ICR instrument were transferred into the ICR cell containing the neutral reactant, and the reactions were analyzed measuring the efficiency of the transfer of a proton to a series of bases with known proton affinity and gas phase basicity as well as the efficiency of the ion-molecule reaction with ethyl vinyl ether. Both reaction types show that the ions C16H17+ produced by chemical ionization (CI) consist of two sets of isomeric ions A and B which exhibit distinctly different behavior on deprotonation and of the reaction with ethyl methyl ether. Isomer(s) A (about 65% of the ion population) react efficiently with this vinyl ether by an addition/elimination process typical of primary and secondary benzylic carbenium ions, while isomer B (about 35% of the ion population) undergoes only an ineffective deprotonation by the vinyl ether. By bracketing deprotonation, it is shown that A is actually composed of two isomers A1 and A2 with slightly different proton affinity and gas phase basicity. These two ions have been identified using CA-mass spectrometry as protonated 3 phenethylstyrene (A1) and protonated 4-phenethylstyrene (A2). The CA-mass spectrum of the isomer B indicated that these ions C16H17+ correspond to protonated 1-(ethyl phenyl)-1-phenyl-ethene. This agrees with the rather strong basicity of the conjugated base of ions B, which results in a slow deprotonation. A protonated 1-(ethyl phenyl)-1-phenyl-ethene can arise from a protonated 2 phenethylstyrene by H- and subsequent phenyl shifts, but requires the preceding rearrangement of the protonated [2.2]-paracyclophane into the protonated isomer "[2.2]-orthocyclophane" - the 1,5-dibenzocyclooctadiene. The possibility of such a deep-sited rearrangement was studied by the computation of the relevant reaction routes applying DFT-methods at the level B3LYP/6-311+g(3d,2p)//B3LYP/3 21g) to analyze the reaction mechanisms. PMID- 29183193 TI - Mass spectrometric characterization of protein structures and protein complexes in condensed and gas phase. AB - Proteins are essential for almost all physiological processes of life. They serve a myriad of functions which are as varied as their unique amino acid sequences and their corresponding three-dimensional structures. To fulfill their tasks, most proteins depend on stable physical associations, in the form of protein complexes that evolved between themselves and other proteins. In solution (condensed phase), proteins and/or protein complexes are in constant energy exchange with the surrounding solvent. Albeit methods to describe in-solution thermodynamic properties of proteins and of protein complexes are well established and broadly applied, they do not provide a broad enough access to life-science experimentalists to study all their proteins' properties at leisure. This leaves great desire to add novel methods to the analytical biochemist's toolbox. The development of electrospray ionization created the opportunity to characterize protein higher order structures and protein complexes rather elegantly by simultaneously lessening the need of sophisticated sample preparation steps. Electrospray mass spectrometry enabled us to translate proteins and protein complexes very efficiently into the gas phase under mild conditions, retaining both, intact protein complexes, and gross protein structures upon phase transition. Moreover, in the environment of the mass spectrometer (gas phase, in vacuo), analyte molecules are free of interactions with surrounding solvent molecules and, therefore, the energy of inter- and intramolecular forces can be studied independently from interference of the solvating environment. Provided that gas phase methods can give information which is relevant for understanding in-solution processes, gas phase protein structure studies and/or investigations on the characterization of protein complexes has rapidly gained more and more attention from the bioanalytical scientific community. Recent reports have shown that electrospray mass spectrometry provides direct access to six prime protein complex properties: stabilities, compositions, binding surfaces (epitopes), disassembly processes, stoichiometries, and thermodynamic parameters. PMID- 29183194 TI - Multidimensional mass spectrometry characterization of isomeric biodegradable polyesters. AB - The biodegradable polyester copolymer poly(propylene fumarate) (PPF) is increasingly utilized in bone tissue engineering studies due to its suitability as inert cross-linkable scaffold material. The well-defined poly(propylene fumarate) oligomers needed for this purpose are synthesized by post polymerization isomerization of poly(propylene maleate), which is prepared by ring opening polymerization of maleic anhydride and propylene oxide. In this study, multidimensional mass spectrometry methodologies, interfacing matrix assisted laser desorption ionization and electrospray ionization with mass analysis, tandem mass spectrometry fragmentation and/or ion mobility mass spectrometry, have been employed to characterize the composition, end groups, chain connectivity and isomeric purity of the isomeric copolyesters poly(propylene maleate)and poly(propylene fumarate). It is demonstrated that the polymerization catalyst is incorporated into the polymer chain (as the initiating chain end) and that the poly(propylene maleate) to poly(propylene fumarate) isomerization using an amine base proceeds with quantitative yield. Hydrolytic degradation is shown not to alter the double bond geometry of the poly(propylene fumarate) or poly(propylene maleate) chains.

AB - Antibody drug conjugates are increasingly being researched for the treatment of cancer. Accurate and reliable characterization of ADCs is inevitable for their development as potential therapeutic agent. Different analytical techniques have been used in order to decipher heterogeneous nature of antibody drug conjugates, enabling successful characterization. This review will summarize specially three major analytical tools i.e. UV-Vis spectroscopy, liquid chromatography, and mass spectrometry used in characterization of antibody drug conjugates. In this review, major challenges during analysis due to the inherent features of analytical techniques and antibody drug conjugates are summarized along with the modifications intended to address each challenge. PMID- 29183196 TI - Substituent effects in the decarboxylation reactions of coordinated arylcarboxylates in dinuclear copper complexes, [(napy)Cu2(O2CC6H4X)]+ ?. AB - A combination of gas-phase ion trap mass spectrometry experiments and density functional theory (DFT) calculations have been used to examine the role of substituents on the decarboxylation of 25 different coordinated aromatic carboxylates in binuclear complexes, [(napy)Cu2(O2CC6H4X)]+, where napy is the ligand 1,8-naphthyridine (molecular formula, C8H6N2) and X = H and the ortho ( o), meta ( m) and para ( p) isomers of F, Br, CN, NO2, CF3, OAc, Me and MeO. Two competing unimolecular reaction pathways were found: decarboxylation to give the organometallic cation [(napy)Cu2(C6H4X)]+ or loss of the neutral copper benzoate to yield [(napy)Cu]+. The substituents on the aryl group influence the branching ratios of these product channels, but decarboxylation is always the dominant pathway. Density functional theory calculations reveal that decarboxylation proceeds via two transition states. The first enables a change in the coordination mode of the coordinated benzoate in [(napy)Cu2(O2CC6H4X)]+ from the thermodynamically favoured O, O-bridged form to the O-bound form, which is the reactive conformation for the second transition state which involves extrusion of CO2 with concomitant formation of the CO2 coordinated organometallic cation, [(napy)Cu2(C6H4X)(CO2)]+, which then loses CO2 in the final step to yield [(napy)Cu2(C6H4X)]+. In all cases the barrier is highest for the second transition state. The o-substituted benzoates show a lower activation energy than the m-substituted ones, while the p-substituted ones have the highest energy, which is consistent with the experimentally determined normalised collision energy required to induce fragmentation of [(napy)Cu2(O2CC6H4X)]+. PMID- 29183197 TI - Proton affinities and ion enthalpies. AB - Proton affinities of a number of alkyl acetates (CH3-C(=O)-OR) and of methyl alkanoates (R-C(=O)-OCH3, R=H, alkyl) have been assembled from the literature or measured using the kinetic method. It was observed that the proton affinities for the isomeric species CH3-C(=O)-OR and R-C(=O)-OCH3 are almost identical, an unexpected result as the charge in these protonated ester molecules is largely at the keto carbon atom and so this site should be more sensitive to alkyl substitution. Analysis of the data, including those from lone pair ionisation and core-electron ionisation experiments available from the literature, indicate that after protonation, extensive charge relaxation (or polarisation) takes place (as is also the case, according to the literature, after core-electron ionisation). By contrast, after lone pair ionisation, which results in radical cations, such relaxation processes are relatively less extensive. As a consequence, changes in ion enthalpies of these protonated molecules follow more closely the changes in neutral enthalpies, compared with changes in enthalpies of the corresponding radical cations, formed by electron detachment. Preliminary analyses of published energetic data indicate that the above finding for organic esters may well be another example of a more general phenomenon. PMID- 29183198 TI - Evaluation of calculated negative mode ion mobilities of small molecules in air. AB - Ion mobility spectrometry is a well-known technique employed for the detection and analysis of gaseous substances. In pharmaceutical applications, it is furthermore used for structural analysis of compounds, especially in combination with mass spectrometry. In this field, the comparison of calculated collision cross sections and ion mobilities of theoretic model compounds with experimental values measured with ion mobility spectrometers helps to determine the compound's structure. For positive mode ion mobility spectrometry, the calculated mobilities using the Trajectory Method show in general a deviation of 10% or less from experimental values. In this article, it was analyzed how well the calculated values reproduce the experimental values obtained with negative mode ion mobility spectrometry including symmetric and asymmetric analyte clusters. Furthermore, the influence of four different partial charge models on the results was investigated. PMID- 29183199 TI - Exploration of doubtful cases of leucine and isoleucine discrimination in mass spectrometric peptide sequencing by electron-transfer and higher-energy collision dissociation-based method. AB - Electron-transfer dissociation (ETD) and electron-transfer and higher-energy collision dissociation (EThcD) spectra of short tryptic peptides with leucine/isoleucine residues in neighboring positions demonstrate intensive w ions. On the contrary, u-ions possess very low intensities (if present at all). Therefore radical site migration is negligible in the applied conditions while ETD (EThcD) spectra allow for the reliable discrimination of the isomeric residues in the sequencing process. The presence of a fragment ion 43.055 mass units lower than z2-ion of peptides with IK sequence at their C-termini was shown to be a result of alternative fragmentation starting from the loss of propylammonium ion from the doubly protonated peptide molecule and formation of an oxazole fragment ion.

Former investigations by photodissociation as well as collision-induced dissociation experiments used to induce a loss of C3H8 from the diethylamino group. The position of the additional proton in [M + H]+ ions is important due to the sequences of radical fragmentation reactions. Two possibilities arise. First, a charge is located at the azo group leading to a methyl radical loss. The second possibility is that the charge has been located on the aniline nitrogen of the molecule resulting in an ethyl radical loss. Only o-ethyl red has shown the overall loss of C3H8 in a two-step radical reaction mechanism. Nevertheless, p-ethyl red and ethyl yellow have shown systematic fragmentation reactions as well. Loss of C3H8 has not been likely regarding both these molecules. All experimental findings together with quantum chemical calculations as well as kinetic calculations support the proposed fragmentation mechanisms of the three azo dyes.

While genetic research showed the remarkable homogeneity of these regions, surname-based studies instead suggested low population mobility, hence potential structuring. AIM: In order to better understand these different patterns, this study (1) thoroughly analysed the surname structure of Sicily and Southern Italy and (2) tested its relationships with a wide set of molecular markers. SUBJECTS AND METHODS: Surname data were collected from 1213 municipalities and compared to uniparental and autosomal genetic markers typed in ~300 individuals from 8-10 populations. Surname analyses were performed using different multivariate methods, while comparisons with genetic data relied on correlation tests. RESULTS: Surnames were clearly structured according to regional geographic patterns, which likely emerged because of recent isolation-by distance-like population dynamics. In general, genetic markers, hinting at a pervasive homogeneity, did not correlate with surname distribution. However, long autosomal haplotypes (>5 cM) that compared to genotypic (SNPs) data identify more "recent" relatedness, showing a clear association with surname patterns. CONCLUSION: The apparent contradiction between surname structure and genetic homogeneity was resolved by figuring surnames as recent "ripples" deposited on a vast and ancient homogeneous genetic "surface".

AB - To evaluate outcomes and prognostic markers among children with relapsed Hodgkin lymphoma (HL) treated with autologous stem cell transplant (ASCT), we conducted a retrospective analysis of 36 consecutive pediatric patients treated at Memorial Sloan Kettering Cancer Center from 1989 to 2013. With a median follow-up of 9.6 years, the 10-year overall survival (OS) and event-free survival (EFS) were 74.1 and 67.1% respectively. Absence of B-symptoms, chemotherapy-sensitive disease, and transplant date after 1997 were each associated with superior EFS [HR 0.12 (p = .0015), 0.18 (p = .0039), and 0.17 (p = .0208), respectively]. Childhood Hodgkin International Prognostic Score at relapse (R-CHIPS) was calculated in a subset of patients (n = 22) and a lower score was associated with improved OS (HR 0.29, p = .0352) and a trend toward improved EFS (HR 0.38, p = .0527). In summary, ASCT results in durable remission for the majority of pediatric patients with relapsed HL. R-CHIPS should be evaluated in larger cohorts as a potential predictive tool.

AB - OBJECTIVE: Biliary forceps biopsies are essential for differentially diagnosing biliary strictures and evaluating the preoperative superficial intraductal spread of bile duct cancers; however, these biopsies are technically demanding and time consuming. Using controllable biopsy-forceps (C-BF), which enable the tip's angle to be adjusted by up to 90 degrees , may facilitate the procedure and improve the diagnostic yield for biliary biopsies. This study aimed to examine the efficacy of C-BF associated with the diagnosis of biliary strictures. MATERIALS AND METHOD: Between 2009 and 2015, 110 patients with biliary strictures underwent biliary biopsies using C-BF. We retrospectively evaluated the diagnostic yield of C-BF for biliary strictures and determined the success rate associated with obtaining adequate samples during mapping biopsies to evaluate the superficial intraductal tumor spread. RESULTS: The technical success rate for biliary biopsies using C-BF was 99% (109/110). The sensitivity, specificity and accuracy of the diagnoses of biliary strictures were 60% (46/77), 100% (33/33) and 72% (79/110), respectively. Regarding the mapping biopsy procedures, adequate samples were successfully obtained from 96% (22/23), 92% (11/12), 80% (12/15), 75% (9/12) and 31% (5/16) of the intrapancreatic common bile ducts, upper common bile ducts, confluences of the hepatic ducts, right intrahepatic bile ducts and left intrahepatic bile ducts, respectively. CONCLUSIONS: C-BF may facilitate biliary cannulation and mapping biopsies of the common bile duct and the right intrahepatic bile duct. However, given that the diagnostic sensitivity was 60%, further modifications are expected and necessary to maximize the utility of the controllable mechanism.

AB - INTRODUCTION: Significant advancements in the treatment of hypercholesterolemia have recently been achieved. However, a considerable level of residual cardiovascular risk still affects patients' outcomes. Atherogenic dyslipidemia is one of the major constituents of residual risk. Fibrates, PPAR alpha agonists, which modify lipid profile and have numerous pleiotropic effects, seem to be drugs of choice in patients with atherogenic dyslipidemia. These drugs are effective both in monotherapy and combined therapy with statins. Areas covered: A review of clinical trials and experimental studies on fibrates and their use in the treatment of lipid disorders has been performed. Expert commentary: Fibrates are an effective and safe group of drugs to treat patients with atherogenic dyslipidemia. In this particular population of patients, they improve cardiovascular outcomes. Benefits of fibrate treatment extend beyond the impact of lipid profile. Significant improvements in carbohydrate metabolism, adipokines levels, thrombosis and inflammation were also noted.

AB - PURPOSE: The number of mobility aid users continues to rise as the population ages. While mobility aid users rely on public transport due to its affordability, evidence suggests access can be difficult. This study aims to describe people who use mobility aids to access public transport and the role of public transport access in influencing mobility aid choice. METHODS: Sixty-seven mobility aid users participated in telephone surveys which predominantly used a structured quantitative format. Data were analysed descriptively and any additional comments were simply categorized. RESULTS: Thirty-six participants were female (54%), with a total sample mean age of 58.15 years (SD = 14.46). Seventy-two percent lived in metropolitan areas, 48% lived alone, and the sample experienced a variety of conditions including spinal cord injury (37%) and arthritis (18%). Sixty-four percent of all respondents used two or more mobility aids including powered wheelchairs, scooters and walking frames. The most important features when choosing a mobility aid were reliability, turning ability and size. Fifty-two percent of all respondents strongly agreed that public transport is generally accessible. CONCLUSIONS: While work continues to ensure that public transport vehicles and stations are fully accessible, mobility aid users must manage current infrastructure and access a system which has been shown through this research to have many limitations. Mobility aid users, vendors and health professionals need to work together to identify mobility aids that fulfil needs, and are reliable and safe, so that mobility aid users are both "visible and seen" when accessing the public transport network. Implications for rehabilitation Some mobility aid users experience difficulties accessing and using public transport and further research is required to ensure the whole public transport network is fully accessible to people using mobility aids. Many people have more than one seated mobility aid, suggesting people can choose different aids for different purposes and environments. Health professionals may need to increase their involvement in assisting individuals to select and use mobility aids. PMID- 29183205 TI - The elemental changes occurring in the rat liver after exposure to PEG-coated iron oxide nanoparticles: total reflection x-ray fluorescence (TXRF) spectroscopy study. AB - The main goal of this study was to evaluate in vivo effects of low dose of PEG coated magnetic iron oxide nanoparticles (IONPs) on the rat liver. The IONPs was intravenously injected into rats at a dose equaled to 0.03 mg of Fe per 1 kg of an animal body weight. The elemental composition of liver tissue in rats subjected to IONPs action and controls were compared. Moreover, in order to determine the dynamics of nanoparticles (NPs) induced elemental changes, the tissues taken from animals 2 hours, 24 hours, and 7 days from IONPs injection were examined. The analysis of subtle elemental anomalies occurring as a result of IONPs action required application of highly sensitive analytical method. The total reflection X-ray fluorescence spectroscopy perfectly meets such requirements and therefore it was used in this study. The obtained results showed increasing trend of Fe level within liver occurring 2 hours from IONPs injection. One day after NPs administration, the liver Fe content presented the baseline level what suggests only the short-term accumulation of nanoparticles in the organ. The Ca, Cu, and Zn levels changed significantly as a result of NPs action. Moreover, the anomalies in their accumulation were still observed 7 days after IONPs injection. The level of Cu decreased while those of Ca and Zn increased in the liver of NPs-treated animals. The reduced liver Cu, followed by elevated serum level of this element, might be related in triggering the mechanisms responsible for Fe metabolism in the organism. PMID- 29183209 TI - [CME - Transient Global Amnesia]. AB - Transient global amnesia (TGA) is a neurological condition which is still a diagnostic challenge for clinicians. Diagnostic clues are an acute onset of a disturbance of memory, a lack of other focal neurological deficits, and repetitive questioning of the patients about time and circumstances. Although the signs and symptoms are quite typical, making the diagnosis of TGA might still be challenging, depending on the patient's characteristics. Taking a precise history from the patient and his/her next of kin is seminal. This article discusses the typical clinical presentation, pathophysiological hypotheses, the diagnostic clues and the most important differential diagnoses. PMID- 29183208 TI - S100B increases in cyanotic versus noncyanotic infants undergoing heart surgery and cardiopulmonary bypass (CPB). AB - AIMS: S100B has been proposed as a consolidated marker of brain damage in infants with congenital heart disease (CHD) undergoing cardiac surgery and cardiopulmonary bypass (CPB). The present study aimed to investigate whether S100B blood levels in the perioperative period differed in infants complicated or not by cyanotic CHD (CHDc) and correlated with oxygenation status (PaO2). METHODS: We conducted a case-control study of 48 CHD infants without pre-existing neurological disorders undergoing surgical repair and CPB. 24 infants were CHDc and 24 were CHD controls. Blood samples for S100B assessment were collected at six monitoring time-points: before the surgical procedure (T0), after sternotomy but before CPB (T1), at the end of the cross-clamp CPB phase (T2), at the end of CPB (T3), at the end of the surgical procedure (T4), at 24 h postsurgery (T5). RESULTS: In the CHDc group, S100B multiples of median (MoM) were significantly higher (p < .05, for all) from T0 to T5. PaO2 was significantly lower (p < .05, for all) in CHDc infants at T0-T1 and at T4 while no differences (p > .05, for all) were found at T2, T3, T5. Linear regression analysis showed a positive correlation between S100B MoM at T3 and PaO2 (R = 0.84; p < .001). CONCLUSIONS: The present data showing higher hypoxia/hyperoxia-mediated S100B concentrations in CHDc infants suggest that CHDc are more prone to perioperative brain stress/damage and suggest the usefulness of further investigations to detect the "optimal" PaO2 target in order to avoid the side effects associated with reoxygenation during CPB.

AB - OBJECTIVES: Exercise is an important part of disease management in patients with non-alcoholic fatty liver disease (NAFLD), but adherence to current exercise recommendations is poor. Novel low-volume sprint interval training (SIT) protocols with total training time commitments of <=30 min per week have been shown to improve cardiometabolic risk and functional capacity in healthy sedentary participants, but the efficacy of such protocols in the management of NAFLD remains unknown. The aim of the present study was to examine whether a low volume SIT protocol can be used to improve liver function, insulin resistance, body composition, physical fitness, cognitive function and general well-being in patients with NAFLD. METHODS: In the present study, 7 men and 2 women with NAFLD (age: 45 +/- 8 y, BMI: 28.7 +/- 4.1 kg.m-2) completed a 6-week control period followed by 6 weeks of twice-weekly SIT sessions (5-10 * 6-s 'all-out' cycle sprints). Body composition, blood pressure, liver function, metabolic function, functional capacity, cognitive function and quality of life were assessed at baseline, following the control period, and following the SIT intervention. RESULTS: Walking speed during the walk test (+12%), estimated VO2max (+8%), verbal fluency (+44%), and blood platelet count (+12%; all p < 0.05) significantly increased during the control period. These measures remained significantly raised compared to baseline following the SIT intervention, but did not significantly change any further compared to the post-control time-point. Diastolic blood pressure decreased from 87 +/- 10 to 77 +/- 8 mm Hg from the end of the control period to the end of the SIT intervention (p < 0.05). CONCLUSION: This study does not support the use of 6 weeks of a low volume SIT protocol involving twice-weekly sessions with 5-10 * 6-s 'all-out' cycle sprints as an intervention for NAFLD disease management. PMID- 29183221 TI - Duration of anticoagulant therapy in pediatric venous thromboembolism: Current approaches and updates from randomized controlled trials. AB - INTRODUCTION: Compared with the incidence of venous thromboembolism in the adult population, pediatric VTE is rare. Yet, recent data suggest that the incidence of VTE in children is increasing, and little is known about the optimal duration of anticoagulation in pediatrics. Areas covered: This review summarizes current evidence-based adult recommendations and associated clinical trials from which current guidelines on the duration of anticoagulation in children have been extrapolated. It also discusses pediatric expert consensus-based guidelines and current pediatric clinical trials on duration of therapy in pediatric VTE. Expert commentary: The vast majority of pediatric VTE are provoked, and evidence on duration of anticoagulation for pediatric VTE is highly limited, but suggests that a maximum duration of 3 months is reasonable for most patients with provoked VTE, whereas longer duration is likely appropriate for unprovoked VTE. Whether shorter duration than 3 months is optimal for pediatric provoked VTE is as yet unclear. Results from the multinational randomized controlled trial studying the duration of anticoagulant therapy for provoked VTE in patients <21 years old (Kids-DOTT) will be critical to inform the future standard of care in pediatric VTE treatment. PMID- 29183222 TI - The Lifetime of Salience Extends Beyond the Initial Saccade. AB - Several models of selection in search predict that saccades are biased toward conspicuous objects (also referred to as salient objects). Indeed, it has been demonstrated that initial saccades are biased toward the most conspicuous candidate. However, in a recent study, no such bias was found for the second saccade, and it was concluded that the attraction of conspicuous elements is limited to only short-latency initial saccades. This conclusion is based on only a single feature manipulation (orientation contrast) and conflicts with the prediction of influential salience models. Here, we investigate whether this result can be generalized beyond the domain of orientation. In displays containing three luminance annuli (Experiment 1), we find a considerable bias toward the most conspicuous candidate for the second saccade. In Experiment 1, the target could not be discriminated peripherally. When we made the target peripherally discriminable, the second saccade was no longer biased toward the more conspicuous candidate (Experiment 2). Thus, conspicuity plays a role in saccadic selection beyond the initial saccade. Whether second saccades are biased toward conspicuous objects appears to depend on the type of feature contrast underlying the conspicuity and the peripheral discriminability of target properties. PMID- 29183224 TI - Age-related changes in implicit emotion processing. AB - The aim of the present study was to compare the performance of older and younger adults on an emotional priming task. Moreover, a nonemotional priming paradigm was used as a control task to disentangle age-related changes due to emotional processing difficulties from modifications due to a decline of executive inhibitory control abilities. Twenty-two young and 22 older healthy participants completed an emotional priming task and a nonemotional priming task. In the older adult group, reaction times in the emotional priming paradigm were not influenced by any of the prime conditions, whereas both groups exhibited similar facilitation effects induced by the congruent prime in the nonemotional task. The selective lack of an emotional priming effect in older adults shown in this preliminary report suggests that aging-induced changes in the ability to recognize emotions implicitly are directly dependent on emotional processing difficulties and not due to a general age-related modification of cognitive processes. PMID- 29183223 TI - "Just as Canadian as Anyone Else"? Experiences of Second-Class Citizenship and the Mental Health of Young Immigrant and Refugee Men in Canada. AB - In recent years, the experiences of immigrant and refugee young men have drawn attention worldwide. Human-induced environmental disasters, local and global conflicts, and increasingly inequitable distributions of wealth have shaped transnational migration patterns. Canada is home to a large immigrant and refugee population, particularly in its urban areas, and supporting the mental health and well-being of these communities is of critical importance. The aim of this article is to report findings from a qualitative study on the social context of mental health among immigrant and refugee young men, with a focus on their migration and resettlement experiences. Informed by the conceptual lens of social context, a thematic narrative analysis approach was used to examine qualitative data from individual and group interviews with 33 young men (age 15 to 22 years) self-identified as immigrants or refugees and were living in Greater Vancouver, western Canada. Three thematic narratives were identified: a better life, living the (immigrant) dream, and starting again from way below. The narratives characterized the social context for immigrant and refugee young men and were connected by a central theme of negotiating second-class citizenship. Implications include the need for mental health frameworks that address marginalization and take into account the contexts and discourses that shape the mental health of immigrant and refugee populations in Canada and worldwide. PMID- 29183225 TI - Prospective memory functioning in individuals with Parkinson's disease: a systematic review. AB - Objective There is growing interest in investigating prospective memory (PM) functioning in individuals with Parkinson's disease (PD) without dementia because evidence suggests that PM may be impaired in this clinical population. This paper reviews current literature on PM functioning in PD patients with the aim of discussing (i) the potential contribution of executive and episodic memory disorders to PM impairments, (ii) whether PM impairment is an independent disorder in PD or whether it is a sign of mild cognitive impairment (MCI) and (iii) the efficacy of cognitive interventions in treating PM disorders in these patients. Method A search of the relevant literature revealed 21 original research papers and five review/meta-analyses that directly investigated PM abilities in PD samples. Results Analysis of the reported data revealed that both executive functions and episodic memory are involved in the PM performance of patients with PD. Moreover, sparse evidence suggests that PM is not impaired in all PD patients but, rather, that PM deficits may be specifically associated with MCI. Finally, preliminary findings suggest that cognitive interventions may be effective in improving PM functioning in PD patients with MCI who present a well established neuropsychological profile. Conclusions Although some shortcomings of the PM literature on PD patients prevent drawing firm conclusions, this review of current evidence highlights the importance of including PM assessment in the standard neuropsychological evaluation of patients with PD. Moreover, there are indications that ad hoc cognitive programs applied according to the qualitative cognitive profile of patients could improve their PM abilities. PMID- 29183226 TI - Analysis of follow-up at the diagnostic level in the Polish Universal Neonatal Hearing Screening Programme. AB - Objectives Routine analysis showed that between 1 June and 30 November 2014, only 47.6% of expected follow-up visits at the diagnostic level were registered in the Polish Universal Neonatal Hearing Screening Programme central database. We attempted to detect and analyse the reasons for this low percentage. Methods A telephone survey questionnaire was developed for parents whose children had not registered for consultation at the diagnostic level, or had not received a final diagnosis according to the programme database. Questions aimed to verify the database records and compare these with information received from and given to parents. From the 7888 children not registered at the diagnostic level, 3239 records were randomly selected, i.e. 52.4% of those who had been expected to attend. Results Questions were answered by 1950 parents (60.2% of the selected group). Of these, 52.1% ( n = 734) had attended for diagnostic tests, but this was not recorded in the database. The most common reasons for not attending were the long waiting time for the visit (36.09%), lack of referral to a visit (25.9%) and conscious parent decision (16.35%). Conclusion The telephone survey disclosed omissions in database registration, and that in fact 83.6% of children had attended at the diagnostic level.

AB - Gonadoblastoma is an uncommon ovarian tumor arising primarily in females with gonadal dysgenesis and a 46, XY karyotype. Germ cell tumors arising within and/or overgrowing a gonadoblastoma have been reported. We report a rare case of a malignant mixed germ cell tumor (yolk sac tumor and choriocarcinoma) arising in a gonadoblastoma of the left ovary in a 19-year-old female with a 46, XX karyotype.

PMID- 29183228 TI - Recommendations for buprenorphine and methadone therapy in opioid use disorder: a European consensus. AB - INTRODUCTION: Management of patients with opioid use disorder (OUD) commonly includes opioid agonist therapy (OAT) as a part of an integrated treatment plan. These interventions are associated with proven benefits to the individual and society. Areas covered: The use of methadone and buprenorphine within an integrated treatment plan in the management of patients with OUD: this work provides consensus recommendation on pharmacotherapy in OUD to assist clinicians with practical decision making in this field. Expert opinion: Pharmacotherapy is recommended as part of an integrated OUD treatment approach with psychosocial interventions, with the goal of reducing risks of illicit opioid use, overdose mortality, infection with HIV or HCV, improving health, psychological and social outcomes. Access to OAT should be prioritised in the treatment of OUD. Treatment choices in OUD pharmacotherapy should be based on the needs of the individual and characteristics of medications. Recommendations for choices of OAT are based on clinical efficacy, safety, patient preference, side effects, pharmacological interactions, quality of life, dose titration potential and outcomes (control craving, ongoing opioids consumption or other drugs, and potentially psychiatric comorbidities). Special groups, pregnant women, prisoners, patients with mental health problems have specific needs which must be addressed with expert input. PMID- 29183229 TI - Prevalence of sickle cell disease among Grenadian newborns. AB - Objective To establish the birth prevalence of sickle cell disease in Grenada, with a view to assess the requirement for a population-based neonatal screening programme. Methods A two-year pilot neonatal screening programme, involving the Ministry of Health of Grenada, the Sickle Cell Association of Grenada, and the diagnostic laboratory of hemoglobinopathies of the University Hospital of Guadeloupe, was implemented in 2014-2015 under the auspices of the Caribbean Network of Researchers on Sickle Cell Disease and Thalassemia. Results Analysis of 1914 samples processed identified the following abnormal phenotypes: 10 FS, 2 FSC, 183 FAS, 63 FAC. These data indicate betas and betac allele frequencies of 0.054 and 0.018, respectively. Conclusion Neonatal screening conducted in the framework of this Caribbean cooperation can allow rapid detection and earlier management of affected children. PMID- 29183230 TI - How good are publicly available web services that predict bioactivity profiles for drug repurposing? AB - Drug repurposing provides a non-laborious and less expensive way for finding new human medicines. Computational assessment of bioactivity profiles shed light on the hidden pharmacological potential of the launched drugs. Currently, several freely available computational tools are available via the Internet, which predict multitarget profiles of drug-like compounds. They are based on chemical similarity assessment (ChemProt, SuperPred, SEA, SwissTargetPrediction and TargetHunter) or machine learning methods (ChemProt and PASS). To compare their performance, this study has created two evaluation sets, consisting of (1) 50 well-known repositioned drugs and (2) 12 drugs recently patented for new indications. In the first set, sensitivity values varied from 0.64 (TarPred) to 1.00 (PASS Online) for the initial indications and from 0.64 (TarPred) to 0.98 (PASS Online) for the repurposed indications. In the second set, sensitivity values varied from 0.08 (SuperPred) to 1.00 (PASS Online) for the initial indications and from 0.00 (SuperPred) to 1.00 (PASS Online) for the repurposed indications. Thus, this analysis demonstrated that the performance of machine learning methods surpassed those of chemical similarity assessments, particularly in the case of novel repurposed indications. PMID- 29183231 TI - In silico prediction of multiple-category classification model for cytochrome P450 inhibitors and non-inhibitors using machine-learning method. AB - The cytochrome P450 (CYP) enzyme superfamily is involved in phase I metabolism which chemically modifies a variety of substrates via oxidative reactions to make them more water-soluble and easier to eliminate. Inhibition of these enzymes leads to undesirable effects, including toxic drug accumulations and adverse drug drug interactions. Hence, it is necessary to develop in silico models that can predict the inhibition potential of compounds for different CYP isoforms. This study focused on five major CYP isoforms, including CYP1A2, 2C9, 2C19, 2D6 and 3A4, that are responsible for more than 90% of the metabolism of clinical drugs. The main aim of this study is to develop a multiple-category classification model (MCM) for the major CYP isoforms using a Laplacian-modified naive Bayesian method. The dataset composed of more than 4500 compounds was collected from the PubChem Bioassay database. VolSurf+ descriptors and FCFP_8 fingerprint were used as input features to build classification models. The results demonstrated that the developed MCM using Laplacian-modified naive Bayesian method was successful in classifying inhibitors and non-inhibitors for each CYP isoform. Moreover, the accuracy, sensitivity and specificity values for both training and test sets were above 80% and also yielded satisfactory area under the receiver operating characteristic curve and Matthews correlation coefficient values. PMID- 29183232 TI - A QSAR and molecular modelling study towards new lead finding: polypharmacological approach to Mycobacterium tuberculosis. AB - Developing effective inhibitors against Mycobacterium tuberculosis (Mtb) is a challenging task, primarily due to the emergence of resistant strains. In this study, we have proposed and implemented an in silico guided polypharmacological approach, which is expected to be effective against resistant strains by simultaneously inhibiting several potential Mtb drug targets. A combination of pharmacophore and QSAR based virtual screening strategy taking three key targets such as InhA (enoyl-acyl-carrier-protein reductase), GlmU (N-acetyl-glucosamine-1 phosphate uridyltransferase) and DapB (dihydrodipicolinate reductase) have resulted in initial 784 hits from Asinex database of 435,000 compounds. These hits were further subjected to docking with 33 Mtb druggable targets. About 110 potential polypharmacological hits were taken by integrating the aforementioned screening protocols. Further screening was conducted by taking various parameters and properties such as cell permeability, drug-likeness, drug-induced phospholipidosisand structural alerts. A consensus analysis has yielded 59 potential hits that pass through all the filters and can be prioritized for effective drug-resistant tuberculosis. This study proposes about nine potential hits which are expected to be promising molecules, having not only drug-like properties, but also being effective against multiple Mtb targets. PMID- 29183233 TI - Complex Dynamics in the Basal Ganglia: Health and Disease Beyond the Motor System. AB - The rate and oscillatory hypotheses are the two main current frameworks of basal ganglia pathophysiology. Both hypotheses have emerged from research on movement disorders sharing similar conceptualizations. These pathological conditions are classified either as hypokinetic or hyperkinetic, and the electrophysiological hallmarks of basal ganglia dysfunction are categorized as prokinetic or antikinetic. Although nonmotor symptoms, including neurobehavioral symptoms, are a key manifestation of basal ganglia dysfunction, they are uncommonly accounted for in these models. In patients with Parkinson's disease, the broad spectrum of motor symptoms and neurobehavioral symptoms challenges the concept that basal ganglia disorders can be classified into two categories. The profile of symptoms of basal ganglia dysfunction is best characterized by a breakdown of information processing, accompanied at an electrophysiological level by complex alterations of spiking activity from basal ganglia neurons. The authors argue that the dynamics of the basal ganglia circuit cannot be fully characterized by linear properties such as the firing rate or oscillatory activity. In fact, the neuronal spiking stream of the basal ganglia circuit is irregular but has temporal structure. In this context, entropy was introduced as a measure of probabilistic irregularity in the temporal organization of neuronal activity of the basal ganglia, giving place to the entropy hypothesis of basal ganglia pathology. Obtaining a quantitative characterization of irregularity of spike trains from basal ganglia neurons is key to elaborating a new framework of basal ganglia pathophysiology. PMID- 29183234 TI - Predictors of Workplace Disability in a Premanifest Huntington's Disease Cohort. AB - Huntington's disease (HD) is an inherited neurodegenerative disease involving motor, cognitive, and psychiatric/behavioral impairments that will eventually affect work role functioning. Few objective data exist regarding predictors of workplace disability in HD. The authors explored the predictors of work impairment and disability in a cross-sectional cohort of 656 employed, premanifest HD (preHD) individuals. In this cohort-the majority of whom were female, urban-dwelling, married/partnered, and working full-time, with minimal cognitive impairment, good function, minimal motor abnormality, and no indication of significant mental health issues-the number of participants who reported that they had missed work due to HD was low (2.4%). However, 12% of the study sample reported experiencing impairment while working due to preHD, 12.2% reported work related activity impairment due to preHD, and 12.7% reported impairment in their overall work ability. Higher numbers of CAG repeats on the mutant allele and having more motor symptoms were associated with significantly higher odds of experiencing workplace impairment. Importantly, several modifiable factors were also found to predict workplace disability. Specifically, higher levels of anxiety symptoms were associated with significantly higher odds of experiencing workplace impairment. Good mental and physical health served as protective factors, where good physical health was associated with 6% lower odds of experiencing impairment or missing work time and good mental health was associated with of 10%-12% lower. The results provide important new knowledge for the development of future targeted intervention trials to support preHD individuals in maintaining their work roles as long as possible. PMID- 29183235 TI - Pneumococcal conjugate vaccine use for the prevention of pneumococcal disease in adults <50 years of age. AB - Introduction; Adults, particularly those with underlying chronic conditions, eg, cardiovascular, liver, and pulmonary diseases and diabetes mellitus, have a persistent pneumococcal disease burden. Thirteen-valent pneumococcal conjugate vaccine (PCV13) is recommended in the United States for all adults aged >=65 years and immunocompromised adults aged <65 years to protect against vaccine serotype (VT) invasive pneumococcal disease (IPD) and pneumonia. PCV13 is not recommended for immunocompetent adults aged >=18 years with comorbidities associated with increased pneumococcal disease risk. Areas covered: This US focused review summarizes PCV13-type IPD and community-acquired pneumonia burden in adults aged <50 years, PCV13 immunogenicity and safety in this population, and adult pneumococcal vaccination recommendations. Expert commentary: Considering (i) PCV13 has demonstrated efficacy against VT-IPD and pneumonia in adults aged >=65 years (with or without underlying chronic conditions), and (ii) immune responses to PCV13 in younger adults are comparable or better than in older adults, PCV13 would likely have similar efficacy in adults aged <50 years. Recommending PCV13 for at-risk adults aged <50 years would provide direct immunologic benefit of a conjugate vaccine and could address an important unmet medical need for pneumococcal pneumonia prevention. Although not directly addressed here, this benefit would likely extend to at-risk adults aged 50-64 years.

PMID- 29183239 TI - The Social Context of Driving Cessation: Understanding the Effects of Cessation on the Life Satisfaction of Older Drivers and Their Social Partners. AB - Older adults with vision loss and a friend or family member were interviewed over a 2-year period. We examined the effects of driving cessation on life satisfaction among older adults and a social contact. Drivers' use of public transportation was examined as a moderator. Driving cessation was associated with a decline in life satisfaction among social partners but not for the drivers. Drivers' use of public transportation at baseline moderated the effects of cessation on changes in well-being among social partners, but had little effect on the life satisfaction of the drivers. Life satisfaction was greater among the social partners of ex-drivers who used public transportation more frequently. The association between driving cessation and well-being should be studied in the context of older drivers' social networks. Infrastructure (e.g., subways and buses) that supports transportation needs plays an important role in mitigating the effects of cessation on older adults' social networks. PMID- 29183240 TI - Enhanced "Train and Hope" for Scalable, Cost-Effective Professional Development in Youth Suicide Prevention. AB - BACKGROUND: The knowledge base surrounding how to most effectively prepare and sustain practitioner knowledge and skills for suicide risk assessment and management is limited. AIMS: This study examined the impact of a 6-hr continuing education training, and the effect of a posttraining reminder system, on mental health practitioners' knowledge, attitudes, and behavior surrounding suicide assessment and intervention. METHOD: Data were obtained prior to the training, immediately after the training, and at the 3-month follow-up. Medical record data were abstracted for a subsample of practitioners. Participants were randomly assigned to an e-mail reminder condition or no reminder condition that provided information related to the training. RESULTS: All practitioners demonstrated increase s in suicide assessment knowledge and attitudes for engaging in suicide risk assessments from pre- to posttest, and gains were maintained at the 3-month follow-up. There was no effect of the e-mail reminder on practitioner knowledge, attitudes, or behaviors compared with the condition without the e-mail reminder. The use of e-mail reminders was not associated with any additional changes. LIMITATIONS: Limitations include predominantly self-report and small sample. CONCLUSION: Strategies to effectively change practitioner knowledge, attitudes, and behaviors toward suicidal clients may include continuing education. Efficient and effective designs of reminder systems for augmenting and supporting suicide assessment management training are needed. PMID- 29183241 TI - Alcohol Involvement in Suicide and Self-Harm. AB - BACKGROUND: Alcohol misuse and alcohol consumption are significant risk factors for suicidal behavior. AIMS: This study sought to identify factors associated with alcohol consumption in cases of suicide and nonfatal self-harm presentations. METHOD: Suicide cases in Cork, Ireland, from September 2008 to June 2012 were identified through the Suicide Support and Information System. Emergency department presentations of self-harm in the years 2007-2013 were obtained from the National Self-Harm Registry Ireland. RESULTS: Alcohol consumption was detected in the toxicology of 44% out of 307 suicide cases. Only younger age was significantly associated with having consumed alcohol among suicides. Alcohol consumption was noted in the case notes in 21% out of 8,145 self-harm presentations. Logistic regression analyses indicated that variables associated with having consumed alcohol in a self-harm presentation included male gender, older age, overdose as a method, not being admitted to a psychiatric ward, and presenting out-of-hours. LIMITATIONS: Data was limited to routinely collected variables by the two different monitoring systems. CONCLUSION: Alcohol consumption commonly precedes suicidal behavior, and several factors differentiated alcohol-related suicidal acts. Self-harm cases, in particular, differ in profile when alcohol is consumed and may require a tailored clinical approach to minimize risk of further nonfatal or fatal self-harm. PMID- 29183242 TI - Blurred Boundaries - A Qualitative Study of How Acts of Self-Harm and Attempted Suicide Are Defined by Mental Health Practitioners. AB - BACKGROUND: There is no commonly accepted definition of the term self-harm, and there is an ongoing debate about whether or not it should include acts of attempted suicide. The use of this language in clinical practice has not previously been explored. AIMS: To investigate if, and how, practitioners distinguish between acts of self-harm and attempted suicide, and present any implications for practice. METHOD: We conducted semistructured interviews with a random sample of 18 frontline practitioners from 10 mental health wards and completed a thematic analysis of interview data. RESULTS: Most participants described self-harm and attempted suicide as distinct behaviors. Characteristics of the act, disclosures of intent, and the level of distress observed were commonly used to differentiate between self-harm and attempted suicide. Very few participants believed that people who self-harm may also feel suicidal. Practitioners confidently described two different behaviors, yet self-harm and attempted suicide were often conflated, revealing the challenges and complexities associated with the separation of these acts in clinical practice. LIMITATIONS: Clinicians working in other settings or disciplines may have different views. Participants' accounts may not be an accurate representation of what happens in practice. CONCLUSION: This study adds to a body of evidence which argues against the dichotomous separation of these behaviors into acts of suicidal and nonsuicidal self-harm.Our findings suggest there is no common understanding of the boundaries between self-harm and attempted suicide among frontline clinicians. The language currently used, and consequent practice, particularly with regard to risk assessment, is problematic. Efforts should be made to operationalize terms around suicidal behavior and to incorporate these into training for clinical staff. PMID- 29183243 TI - Telephone Crisis Support Workers' Intentions to Use Recommended Skills While Experiencing Functional Impairment. AB - BACKGROUND: Empathic engagement with distressed others can lead to elevated symptoms of psychological distress and functional impairment, which preclude helping professionals' delivery of optimal patient care. Whether telephone crisis support workers are impacted in a similar way is not currently reported in the literature. AIMS: This study examined the relationship between functional impairment and intentions to use recommended support skills in a representative national sample of 210 telephone crisis support workers. METHOD: Participants completed an online survey including measures of functional impairment and intentions to use recommended telephone crisis support skills with callers reporting suicidal ideation, symptoms of depression, and anxiety. RESULTS: As a group, participants who experienced greater functional impairment during the past month reported significantly lower intentions to use recommended support skills with callers than those who reported lower functional impairment. LIMITATIONS: Future research is needed to clarify the extent to which results generalize to telephone crisis support workers from other organizations. CONCLUSION: Results warrant further research to (a) identify determinants of telephone crisis support workers' functional impairment, and (b) for the deliberate management of telephone crisis support workers' functional impairment through developing and/or modifying existing service strategies to optimize workers' psychological well being and delivery of support to callers. PMID- 29183244 TI - Sodium butyrate enhances intestinal integrity, inhibits mast cell activation, inflammatory mediator production and JNK signaling pathway in weaned pigs. AB - The present study aimed to investigate the effects of sodium butyrate on the intestinal barrier and mast cell activation, as well as inflammatory mediator production, and determine whether mitogen-activated protein kinase signaling pathways are involved in these processes. A total of 72 piglets, weaned at 28 +/- 1 d age, were allotted to two dietary treatments (control vs. 450 mg/kg sodium butyrate) for 2 wk. The results showed that supplemental sodium butyrate increased daily gain, improved intestinal morphology, as indicated by greater villus height and villus height:crypt depth ratio, and intestinal barrier function reflected by increased transepithelial electrical resistance and decreased paracellular flux of dextran (4 kDa). Moreover, sodium butyrate reduced the percentage of degranulated mast cells and its inflammatory mediator content (histamine, tryptase, TNF-alpha and IL-6) in the jejunum mucosa. Sodium butyrate also decreased the expression of mast cell-specific tryptase, TNF-alpha and IL-6 mRNA. Sodium butyrate significantly decreased the phosphorylated ratio of JNK whereas not affecting the phosphorylated ratios of ERK and p38. The results indicated that the protective effects of sodium butyrate on intestinal integrity were closely related to inhibition of mast cell activation and inflammatory mediator production, and that the JNK signaling pathway was likely involved in this process. PMID- 29183245 TI - Variation in Practice Pattern of Male Hypogonadism: A Comparative Analysis of Primary Care, Urology, Endocrinology, and HIV Specialists. AB - The objective of the current study was to measure the adherence of guideline based evaluation and treatment of hypogonadism by medical specialty. A retrospective review was performed analyzing patients from a single academic institution within the past 10 years. The cohort of 193 men was grouped according to medical specialty of the diagnosing physician (50 urology, 49 primary care, 44 endocrinology, and 50 HIV medicine). Adherence to guidelines was assessed using the Endocrine Society's criteria. Primary care patients were older compared to the rest of the cohort ( p < .001) but BMI and cardiovascular risk factors were similar ( p = .900). Patients treated by urologists and endocrinologists had the highest percentage of low testosterone findings at initial encounter at 72% ( p < .001). Sixty-two percent of urology patients had low LH or FSH compared to 63.6% for endocrinology and 16% for primary care ( p < .001). As for brain MRI findings, no urology patients had positive findings (0/9) while eight pituitary adenomas (40%) were found by endocrinologists. Forty-five percent of men treated by urologists received TRT without repeat confirmation, compared to 58% of endocrinologists, 77% of primary care, and 88% of HIV medicine ( p < .001). All urology patients had PSA checked before TRT compared to 77.5% of primary care and 61.2% of endocrinology patients ( p = .063). Adherence to the guidelines helps prevent undue over-diagnosis and over-treatment of hypogonadism. This study suggests that adherence to guideline-based screening is varied among specialties. PMID- 29183246 TI - Uptake trends in the Scottish Bowel Screening Programme and the influences of age, sex, and deprivation. AB - Objective Age, sex, and deprivation are known factors influencing colorectal (bowel) cancer screening uptake. We investigated the influence of these factors on uptake over time. Methods Data from the Scottish Bowel Screening Programme (SBoSP) were collected between 2007 and 2014. End-points for analysis were uptake, faecal occult blood test positivity, and disease detection, adjusted for age, sex, deprivation, and year of screening. Results From 5,308,336 individual screening episodes documented, uptake gradually increased with increasing age up to 65-69 and was lower in men than women (52.4% vs. 58.7%, respectively). Deprivation had a significant effect on uptake by men and women of all age groups, with the most deprived least likely to complete a screening test. Uptake has increased with time in both sexes and across the deprivation gradient. The number needed to screen to detect significant neoplasia was significantly lower in men than women overall (170 vs. 365), and this held over all age and deprivation groups. The number needed to screen was also lower in the more deprived population. Conclusions Although lower age, male sex, and increased deprivation are associated with lower bowel cancer screening uptake in Scotland, uptake has increased since SBoSP introduction in all age groups, both sexes, and across the deprivation gradient. Despite a lower uptake, the number needed to screen to find significant disease was lower in men and in those with higher levels of deprivation. PMID- 29183247 TI - Is the devil in the detail? Evidence for S-S learning after unconditional stimulus revaluation in human evaluative conditioning under a broader set of experimental conditions. AB - Whether valence change during evaluative conditioning is mediated by a link between the conditional stimulus (CS) and the unconditional stimulus (US; S-S learning) or between the CS and the unconditional response (S-R learning) is a matter of continued debate. Changing the valence of the US after conditioning, known as US revaluation, can be used to dissociate these accounts. Changes in CS valence after US revaluation provide evidence for S-S learning but if CS valence does not change, evidence for S-R learning is found. Support for S-S learning has been provided by most past revaluation studies, but typically the CS and US have been from the same stimulus category, the task instructions have suggested that judgements of the CS should be based on the US, and USs have been mildly valenced stimuli. These factors may bias the results in favour of S-S learning. We examined whether S-R learning would be evident when CSs and USs were taken from different categories, the task instructions were removed, and more salient USs were used. US revaluation was found to influence explicit US evaluations and explicit and implicit CS evaluations, supporting an S-S learning account and suggesting that past results are stable across procedural changes. PMID- 29183248 TI - Assessing the landscape of percutaneous coronary chronic total occlusion treatment in Belgium and Luxembourg: the Belgian Working Group on Chronic Total Occlusions (BWGCTO) registry. AB - BACKGROUND: Important developments in materials, devices, and techniques have improved outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI), and resulted in a growing interest in CTO-PCI. The Belgian Working Group on Chronic Total Occlusions (BWGCTO) working group aims to assess the evolution within the CTO-PCI landscape over the next years. METHODS: From May 2016 onwards, patients undergoing CTO-PCI were included in the BWGCTO registry by 15 centres in Belgium and Luxemburg. Baseline, angiographic, and procedural data were collected. Here, we report on the one-year in-hospital outcomes. RESULTS: Over the course of one year, 411 procedures in 388 patients were included with a mean age of 64 +/- 11 years. The majority were male (81%). Relatively complex CTOs were treated (Japanese CTO score =2.2 +/- 1.2) with a high procedure success rate (82%). Patient- and lesion-wise success rates were 83 and 85%, respectively. Major adverse in-hospital events were acceptably low (3.4%). Antegrade wire escalation technique was applied most frequently (82%). On the other hand, antegrade dissection and re-entry and retrograde strategies were more frequently applied in higher volume centres and successful for lesions with higher complexity. CONCLUSION: Satisfactory procedural outcomes and a low rate of adverse events were obtained in a complex CTO population, treated by operators with variable experience levels. Antegrade wire escalation was the preferred strategy, regardless of operator volume. PMID- 29183249 TI - Truth-telling, decision-making, and ethics among cancer patients in nursing practice in China. AB - BACKGROUND: Truth-telling toward terminally ill patients is a challenging ethical issue in healthcare practice. However, there are no existing ethical guidelines or frameworks provided for Chinese nurses in relation to decision-making on truth telling of terminal illness and the role of nurses thus is not explicit when encountering this issue. OBJECTIVES: The intention of this paper is to provide ethical guidelines or strategies with regards to decision-making on truth-telling of terminal illness for Chinese nurses. METHODS: This paper initially present a case scenario and then critically discuss the ethical issue in association with ethical principles and philosophical theories. Instead of focusing on attitudes toward truth disclosure, it aims to provide strategies regarding this issue for nurses. It highlights and discusses some of the relevant ethical assumptions around the perceived role of nurses in healthcare settings by focusing on nursing ethical virtues, nursing codes of ethics, and philosophical perspectives. And Confucian culture is discussed to explicate that deontology does not consider family-oriented care in China. CONCLUSION: Treating each family individually to explore the family's beliefs and values on this issue is essential in healthcare practice and nurses should tailor their own approach to individual needs regarding truth-telling in different situations. Moreover, the Chinese Code of Ethics should be modified to be more specific and applicable. Finally, a narrative ethics approach should be applied and teamwork between nurses, physicians and families should be established to support cancer patients and to ensure their autonomy and hope. Ethical considerations: This paper was approved by the Ethics Committee of The Second Affiliated Hospital of Guangzhou Medical University. The authors have obtained consent to use the case study and it has been anonymised to preserve the patient's confidentiality. PMID- 29183250 TI - Internalized stigma in people with severe mental illness in rural China. AB - BACKGROUND: It is unknown whether there are differences in self-stigma among persons with different types of severe mental illness (SMI) in rural communities. AIM: This study was to examine the differences of self-stigma and its correlates in persons with schizophrenia, major depressive disorder or bipolar disorder in a rural community in China. METHODS: A total of 453 persons with schizophrenia, major depressive disorder or bipolar disorder in a rural community participated in the study. The Internalized Stigma of Mental Illness (ISMI) was used to measure self-stigma. The t-test and analyses of variance (ANOVA) were used to examine the differences in mean scores of ISMI and subscales among the three diagnoses. Logistic regression was used to explore the contributing factors to the level of self-stigma among the three groups. RESULTS: Self-stigma was moderate and severe with 94.7% of the total sample. Persons with schizophrenia had significantly higher mean scores of total ISMI, alienation and discrimination experience than those with bipolar disorders. Lower family income was significantly associated with higher levels of self-stigma in persons with schizophrenia and major depressive disorder. Factors predicting the level of self stigma among the three groups were various. CONCLUSION: Self-stigma is common and severe in persons with schizophrenia, major depressive disorder and bipolar disorder, especially those with lower income status in rural community in China. Persons with schizophrenia may have higher levels of self-stigma than those with bipolar disorder. Individual-level interventions should be developed to reduce self-stigma among persons with SMI in Chinese rural communities. PMID- 29183251 TI - Promoting Postpartum Mental Health in Fathers: Recommendations for Nurse Practitioners. AB - The transition to fatherhood can challenge the mental health of first-time fathers and heighten their risk for postpartum depression (PPD). Paternal PPD not only affects the individual, but relationships with partners and children as well. This scoping review explores paternal PPD, highlighting the factors for and impacts of paternal PPD, the experiences of first-time fathers during the postnatal period, including their knowledge gaps and learning preferences. Drawing on the scoping review findings, recommendations are made for postnatal programs to improve the inclusion of new fathers amid describing how nurse practitioners can promote men's mental health in the postpartum period. PMID- 29183252 TI - Sexual Dysfunction in a Patient Taking Ledipasvir/Sofosbuvir for the Treatment of Hepatitis C: A Case Report. AB - Sexual dysfunction is a bothersome side effect of several medications, though it has not yet been reported with the use of ledipasvir/sofosbuvir for the treatment of hepatitis C. However, sexual dysfunction is a potentially unrecognized side effect of ledipasvir/sofosbuvir that could result in nonadherence and treatment failure. We report a case of a 42-year-old man with a sudden onset of sexual dysfunction with the initiation of ledipasvir/sofosbuvir for the treatment of hepatitis C. The patient had no prior history or risk factors for the development of sexual dysfunction. His symptoms resolved upon discontinuation of ledipasvir/sofosbuvir after a successful 12-week course. Clinicians should be aware that sexual dysfunction is a possible side effect of ledipasvir/sofosbuvir and educate patients appropriately. Adherence should be emphasized as the risks of untreated hepatitis C virus far outweigh transient sexual dysfunction. PMID- 29183253 TI - Implementation of a Cardiac Transitions of Care Pilot Program: A Prospective Study of Inpatient and Outpatient Clinical Pharmacy Services for Patients With Heart Failure Exacerbation or Acute Myocardial Infarction. AB - BACKGROUND: Pharmacists may assist with reducing 30-day readmission rates for patients with heart failure (HF) exacerbation or acute myocardial infarction (AMI) by promoting medication adherence. OBJECTIVE: To determine the change in 30 day readmission rates for patients with HF exacerbation or AMI after implementation of a "high-touch" standard of care. METHODS: Patients admitted with HF exacerbation, non-ST-segment elevation AMI, or ST-segment elevation AMI from August 1, 2013, to June 30, 2015, were included in this prospective study. Patients were educated while in the inpatient setting and followed up in the outpatient setting through telephone contact and scheduling a medication therapy management (MTM) appointment with a pharmacist. Data were collected by pharmacy personnel involved in the implementation of the intervention. RESULTS: Within the HF and AMI arms, 100 and 93 patients, respectively, were included in the study. The 30-day readmission rates were 24% and 17.2% for HF and AMI, respectively, which were not statistically significant when compared to historical institutional readmission rates prior to study initiation (18.2% for HF, P = .238; 11.4% for AMI, P = .252). CONCLUSION: A "high-touch" pharmacist-driven transitions of care program may affect 30-day readmission rates for patients with HF exacerbation or AMI; potential processes for initiating transitions of care programs are provided. PMID- 29183254 TI - Feasibility study on the use of thiosulfate to remediate mercury-contaminated soil. AB - The feasibility of using sodium thiosulfate to remediate the mercury-contaminated soil around a local chemical plant in northeastern China has been investigated. Effects of solid-to-reagent ratio and temperature on mercury extraction from soil samples with thiosulfate solutions were examined. BCR (European Community Bureau of Reference) analysis indicated that more than 90% of weak acid soluble and reducible mercury in the soil sample could be extracted by thiosulfate solution. Mercury extraction kinetics can be described by the two-step first-order reaction model in which the readily extractable fraction and the less extractable fraction of mercury were associated with their own rate constants. Mercury extraction with thiosulfate solutions could be slightly promoted when the contaminated soil was pre-oxidized with hydrogen peroxide. The results suggest that thiosulfate is a potentially effective complexing lixiviant in mercury-contaminated soil remediation. PMID- 29183255 TI - Suckling in litters with different sizes, and early and late swimming exercise differentially modulates anxiety-like behavior, memory and electrocorticogram potentiation after spreading depression in rats. AB - OBJECTIVE: Analyze the hypothesis that swimming exercise, in rats suckled under distinct litter sizes, alters behavioral parameters suggestive of anxiety and recognition memory, and the electrocorticogram potentiation that occurs after the excitability-related phenomenon that is known as cortical spreading depression (CSD). METHODS: Male Wistar rats were suckled in litters with six or 12 pups (L6 and L12 groups). Animals swam at postnatal days (P) 8-23, or P60-P75 (early exercised or late-exercised groups, respectively), or remained no-exercised. Behavioral tests (open field - OF and object recognition - OR) were conducted between P77 and P80. Between P90 and P120, ECoG was recorded for 2 hours. After this 'baseline' recording, CSD was elicited every 30 minutes over the course of 2 hours. RESULTS: Early swimming enhanced the number of entries and the percentage of time in the OF-center (P < 0.05). In animals that swam later, this effect occurred in the L6 group only. Compared to the corresponding sedentary groups, OR test showed a better memory in the L6 early exercised rats, and a worse memory in all other groups (P < 0.05). In comparison to baseline values, ECoG amplitudes after CSD increased 14-43% for all groups (P < 0.05). In the L6 condition, early swimming and late swimming, respectively, reduced and enhanced the magnitude of the post-CSD ECoG potentiation in comparison with the corresponding L6 no exercised groups (P < 0.05). DISCUSSION: Our data suggest a differential effect of early- and late-exercise on the behavioral and electrophysiological parameters, suggesting an interaction between the age of exercise and the nutritional status during lactation. PMID- 29183256 TI - Experimental and Mathematical Analyses Relating Circadian Period and Phase of Entrainment in Neurospora crassa. AB - Circadian rhythms are observed in most organisms on earth and are known to play a major role in successful adaptation to the 24-h cycling environment. Circadian phenotypes are characterized by a free-running period that is observed in constant conditions and an entrained phase that is observed in cyclic conditions. Thus, the relationship between the free-running period and phase of entrainment is of interest. A popular simple rule has been that the entrained phase is the expression of the period in a cycling environment (i.e., that a short period causes an advanced phase and a long period causes a delayed phase). However, there are experimental data that are not explained by this simple relationship, and no systematic study has been done to explore all possible period-phase relationships. Here, we show the existence of stable period-phase relationships that are exceptions to this rule. First, we analyzed period-phase relationships using populations with different degrees of genome complexity. Second, we generated isogenic F1 populations by crossing 14 classical period mutants to the same female and analyzed 2 populations with a short period/delayed phase and a long period/advanced phase. Third, we generated a mathematical model to account for such variable relationships between period and phase. Our analyses support the view that the circadian period of an organism is not the only predictor of the entrained phase. PMID- 29183257 TI - Sodium bicarbonate improves 4 km time trial cycling performance when individualised to time to peak blood bicarbonate in trained male cyclists. AB - The aim of this study was to investigate the effects of sodium bicarbonate (NaHCO3) on 4 km cycling time trial (TT) performance when individualised to a predetermined time to peak blood bicarbonate (HCO3-). Eleven male trained cyclists volunteered for this study (height 1.82 +/- 0.80 m, body mass (BM) 86.4 +/- 12.9 kg, age 32 +/- 9 years, peak power output (PPO) 382 +/- 22 W). Two trials were initially conducted to identify time to peak HCO3- following both 0.2 g.kg-1 BM (SBC2) and 0.3 g.kg-1 BM (SBC3) NaHCO3. Thereafter, on three separate occasions using a randomised, double-blind, crossover design, participants completed a 4 km TT following ingestion of either SBC2, SBC3, or a taste-matched placebo (PLA) containing 0.07 g.kg-1 BM sodium chloride (NaCl) at the predetermined individual time to peak HCO3-. Both SBC2 (-8.3 +/- 3.5 s; p < 0.001, d = 0.64) and SBC3 (-8.6 +/- 5.4 s; p = 0.003, d = 0.66) reduced the time to complete the 4 km TT, with no difference between SBC conditions (mean difference = 0.2 +/- 0.2 s; p = 0.87, d = 0.02). These findings suggest trained cyclists may benefit from individualising NaHCO3 ingestion to time to peak HCO3- to enhance 4 km TT performance. PMID- 29183259 TI - Advances in endometrial cancer protein biomarkers for use in the clinic. AB - INTRODUCTION: Endometrial cancer (EC) is the fourth most common cancer in women in developed countries. The identification of sensitive and specific biomarkers to improve early detection of EC is crucial for an appropriate management of this disease, in which 30% of patients are diagnosed only at advanced stages, which is associated with high levels of morbidity and mortality. Despite major efforts and investments made to identify EC biomarkers, no protein has yet reached the stage of clinical application. Areas covered: This review gathers the numerous candidate biomarkers for EC diagnosis proposed in proteomic studies published from 1978 to 2017. Additionally, we summarize limitations associated with the proteomic technologies and study designs employed in those articles. Finally, we address new perspectives in EC biomarker research, including the comprehensive knowledge of previously suggested candidate biomarkers in conjunction with novel mass spectrometry-based proteomic technologies with enhanced sensitivity and specificity not yet applied to EC studies and a directed clinical perspective in the study design. Expert commentary: These ingredients could be the recipe to accelerate the application of protein biomarkers in the clinic. PMID- 29183258 TI - [Transitional and Adolescent Psychiatry in Austria: A Pilot Study on the Attitudes of Experts]. AB - : Transitional and Adolescent Psychiatry in Austria: A Pilot Study on the Attitudes of Experts Abstract. OBJECTIVE: This pilot study establishes baseline data on the current situation of transitional processes in Austrian psychiatry. We sought to gather information on the specific problems and needs occurring during the transition of mentally ill adolescents from child and adolescent to adult psychiatry. METHOD: Professionals (psychiatrists, psychologists, psychotherapists) working in child and adolescent psychiatry and adult psychiatry (N = 86) were assessed by means of an online survey concerning their experience with the transition of young adults. RESULTS: Almost all of the subjects queried (98.8 %) considered the current system inappropriate, and the majority (70.9 %) thought that patients would not tolerate transition from youth to adult psychiatric institutions very well. Only 16.3 % reported having a structured transition protocol at their workplace. Further 83.7 % expressed the need to improve collaboration between adolescent and adult psychiatry. CONCLUSIONS: This sample of Austrian healthcare professionals describes large deficits regarding transitional issues in psychiatry. There is an urgent need to establish structured protocols for transition, especially since experiences occurring during this vulnerable period are crucial to the mental health of young people later in life. PMID- 29183260 TI - Vital statistics and early death predictors of North American professional basketball players: A historical examination. AB - While empirical evidence suggests that elite athletes have superior lifespan outcomes relative to the general population, less is known regarding their causes of death. The purpose of this study was to critically examine the mortality outcomes of deceased National Basketball Association and American Basketball Association players. Death data were collected from publicly available sources until 11 December 2015, and causes of death were categorized using the International Classification of Diseases, Tenth Revision (ICD). Mortality was measured through: i) cause-specific crude death rates (CDR), ii) estimates of death rates per athlete-year (AY), and iii) binary and multinomial regression analyses. We identified 514 causes of death from 787 deceased players (M = 68.1 y +/- 16.0) from 16 different ICD groups, 432 of which were from natural causes. Findings showed similar leading causes of death and CDRs to sex- and race-matched controls, higher death rate differences per AY within time-dependent variables (i.e., birth decade, race, and height), and a higher likelihood of dying below the median age of death for black and taller players, although this was highly confounded by birth decade. More complete knowledge of mortality outcomes would provide broad public health applications and disarm harmful stereotypes of elite athlete health. PMID- 29183261 TI - Self-Reported Participation in Sport/Exercise Among Adolescents and Young Adults With and Without Mild to Moderate Intellectual Disability. AB - BACKGROUND: Physical inactivity is a leading risk factor for mortality. Adults with intellectual disability are extremely inactive, but less is known about physical activity levels in children and youth with intellectual disability. This paper examines the participation by adolescents and young adults with and without mild to moderate intellectual disability in sport/exercise. METHODS: Secondary analysis was undertaken of Next Steps, an annual panel study that followed a cohort from early adolescence into adulthood. Participants with mild to moderate intellectual disability were identified through data linkage with educational records. RESULTS: Sport/exercise participation rates were consistently lower for adolescents and young people with mild to moderate intellectual disability than for their peers without intellectual disability. Matching participants on between group differences in exposure to extraneous risk factors did not impact on these between-group differences in participation in sport/exercise. CONCLUSION: The results support limited existing evidence regarding the low level of participation of children and young people with intellectual disability in sport/exercise compared with their peers. Future work on promoting sport/exercise and physical activity in children and young people with intellectual disability may play a role in helping to reduce the health inequalities experienced by people with intellectual disability. PMID- 29183262 TI - Globus Symptoms in Patients Undergoing Thyroidectomy: Relationships with Psychogenic Factors, Thyroid Disease, and Surgical Procedure. AB - BACKGROUND: The number of patients who need thyroid surgery has increased worldwide in recent decades. Patients with thyroid disease experience globus pharyngeus as a result of direct compression and edema of the surrounding organs. Thyroid surgery is needed to improve these symptoms or as treatment for thyroid cancer. After thyroid surgery, globus symptoms may become worse and may affect the daily life of the patient for a long time. Psychogenic problems have also been thought to cause the globus sensation. A prospective analysis of globus symptoms and psychogenic factors following thyroidectomy was performed. MATERIAL AND METHODS: Patients scheduled to undergo thyroid surgery between February and September 2016 completed the foreign-body sensation in the throat score (FBST; range 0-8.2) and the self-rating depression scale (SDS; range 0-100) preoperatively and three days, one month, three months, six months, and 12 months postoperatively. RESULTS: Long-term follow-up was completed in 616 patients (491 females). A total of 365 patients had thyroid cancer, 169 had benign tumors, and 82 had diffuse goiters with Graves' disease. The percentage of patients who complained about neck discomfort (FBST >2) was 29.4% before surgery. A preoperative high FBST showed a significant direct correlation with a high SDS, but thyroid volume did not. A postoperative high FBST was seen in 75.3% of patients at two days and 78.9% at one month after surgery, and it then gradually decreased to 49.3% at 12 months after surgery. At three days after the operation, the median FBST was significantly higher in patients who had total thyroidectomy with lateral neck dissection or total thyroidectomy only compared to those who had lobectomy only (p < 0.05). These differences were still present 12 months after surgery. A higher preoperative SDS score was also identified as an independent predictor for a high FBST at 12 months after surgery, but not at one or three months postoperatively, on multivariate analyses. CONCLUSION: Preoperative globus symptoms appear directly related to psychological factors. The area of the surgical procedure and preoperative psychological factors were related to persistent neck discomfort.

AB - The spread of adaptive genetic variants in populations is a cornerstone of evolutionary theory but with relatively few biologically well-understood examples. Previous work on the ls-tim variant of timeless, which encodes the light-sensitive circadian regulator in Drosophila melanogaster, suggests that it may have originated in southeastern Italy. Flies characterized by the new allele show photoperiod-related phenotypes likely to be adaptive in seasonal environments. ls-tim may be spreading from its point of origin in Italy by directional selection, but there are alternative explanations for its observed clinal geographical distribution, including balancing selection and demography. From population analyses of ls-tim frequencies collected on the eastern side of the Iberian Peninsula, we show that ls-tim frequencies are inverted compared with those in Italy. This pattern is consistent with a scenario of directional selection rather than latitude-associated balancing selection. Neutrality tests further reveal the signature of directional selection at the ls-tim site, which is reduced a few kb pairs either side of ls-tim. A reanalysis of allele frequencies from a large number of microsatellite loci do not demonstrate any frequent ls-tim-like spatial patterns, so a general demographic effect or population expansion from southeastern Italy cannot readily explain current ls tim frequencies. Finally, a revised estimate of the age of ls-tim allele using linkage disequilibrium and coalescent-based approaches reveals that it may be only 300 to 3000 years old, perhaps explaining why it has not yet gone to fixation. ls-tim thus provides a rare temporal snapshot of a new allele that has come under selection before it reaches equilibrium.

AB - OBJECTIVE: Informed consent is an essential element in doctor-patient relationship. In particular, obtaining valid informed consent from patients with neurocognitive diseases is a critical issue at present. For this reason, we decided to conduct research on elderly patients with Alzheimer's disease ( Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) to assess their capacity to make treatment decisions. METHODS: The experimental group comprised 70 Alzheimer patients who were admitted to the Neurodegenerative Disease Unit of the University of Bari. The control group consisted of 83 elderly patients without neurocognitive disorders who were hospitalized in the Geriatric Unit at the same university. After providing written consent to participate in the research, each subject underwent the following assessments: (a) assessment of comprehension sheet, (b) Neuropsychiatric Inventory (NPI) and Global Functioning Evaluation (GFE), (c) neurological evaluation, (d) neuropsychological assessment with a full battery of tests, (d) The MacArthur Treatment Competence Study (MacArthur Competence Assessment Tool for Treatment (MacCAT-T); understanding, appreciating, reasoning and expressing a choice) and (e) a semi-structured interview administered by the patient's caregiver. RESULTS/CONCLUSION: The present survey was designed to analyze possible qualitative and quantitative correlations between cognitive functioning and capacity to consent in relation to different degrees of severity of the neurodegenerative disorder. A large portion of the patients in our experimental sample did not appear to have the capacity to provide a valid consent. The authors present initial results of this study and discuss their possible implications. PMID- 29183265 TI - When general practitioners meet new evidence: an exploratory ethnographic study. AB - OBJECTIVE: To explore how general practitioners (GPs) think and act when presented with new evidence in relation to planned home birth and a proposal to change information practices. DESIGN: Exploratory ethnographic study of GPs. The GPs were encountered one or more times during a two-year period, 2011-2013, while the author tried to set up formal focus group interviews. Dialogues about the evidence, personal experiences, values and other issues unavoidably occurred. Field notes were written concomitantly. SETTING: Danish GPs, primarily in Copenhagen. SUBJECTS: Fifty Danish GPs. RESULTS: The GPs reacted very differently, both spontaneously and later. Spontaneous reactions were often emotional involving private and professional experiences whereas later reactions were more influenced by rational deliberations. Approximately half the GPs (n = 18) who were asked whether they would personally hand out the local information leaflet about home birth were prepared to do so. The time lag between presentation of the evidence and the GPs' decision to hand out the leaflets was up to one and a half year. CONCLUSIONS: A significant number of GPs were prepared to change their information practices. However, for many GPs, the new evidence challenged previous perceptions, and ample time and resources for dialogue, deliberations and adaptation to local circumstances were required to accommodate change. IMPLICATIONS: Changing information practices on a larger scale will require a systematic approach involving key stakeholders. Key Points Current awareness*Patients and pregnant women should receive evidence-based information about possible choices of care - also in relation to place of birth. Most important results*Doctors often find the new evidence supporting planned home birth counterintuitive and spontaneously react emotionally rather than rationally to the evidence.*The new evidence challenging previous views elicits fast, emotional reactions, later deliberate reflections, perhaps cognitive dissonance and, finally, for some, change in clinical practice. Significance for the readers*The findings may be applicable to other fields where an evidence-based choice between an interventionist and a conservative approach is relevant. PMID- 29183266 TI - Faecal immunochemical tests for the diagnosis of symptomatic colorectal cancer in primary care: the benefit of more than one sample. AB - OBJECTIVE: Faecal immunochemical tests (FITs) are used to screen for colorectal cancer (CRC) and as diagnostic aids in symptomatic patients. However, the number of samples per FIT varies. It is unclear if there is any advantage to analyse multiple-sample FITs in symptomatic patients. DESIGN AND SETTING: This is a post hoc analysis of a retrospective study that included all cases of CRC and adenomas with high-grade dysplasia (HGD) between 2005 and 2009 in the county of Jamtland, Sweden. SUBJECTS: All patients with CRC and adenomas with HGD that initially presented with symptoms to primary care and delivered FITs. MAIN OUTCOME MEASURE: The likelihood of a positive FIT in cases of CRC and adenomas with HGD; when analysing one, two or three samples. RESULTS: Of 195 patients, 160 delivered three-sample FITs. Using the 139 cases in which at least one sample was positive, the likelihood of detecting a positive sample upon analysis of only one of the three samples was 0.91 (95% CI: 0.85-0.95), indicating that 13 positive cases may have been missed. CONCLUSION: Use of a one-sample FIT instead of a three-sample FIT as a diagnostic aid may result in the missing of one tenth of symptomatic CRCs and adenomas with HGD. PMID- 29183267 TI - In silico evaluation of the resistance of the T790M variant of epidermal growth factor receptor kinase to cancer drug Erlotinib. AB - Epidermal growth factor receptor kinase is implicated in cancer development due to either overexpression or activation variants in its functional intracellular kinase domain. Threonine to methionine (Thr 790 Met) is one such variant observed commonly in patients showing resistance to kinase inhibitor drug Erlotinib. Two mechanisms for resistance have been proposed (1) steric hindrance and (2) enhanced binding to ATP. In this study, we employed molecular dynamics simulations and studied both the mechanisms. Extensive simulations and free energy of binding analyses has shown that steric hindrance does not explain appropriately the mechanism for resistance against Erlotinib therapy for this variant. It has been observed that conformational switching from an intermediate intrinsically disordered C-helix conformation is required for completion of the kinase's catalytic cycle. Our study substantiates that T790M variant has greater tendency for early transition to this intrinsically disordered C-helix intermediate state. We propose that enhanced catalytic efficiency in addition to enhanced ATP binding explains mechanism of T790M resistance to drug Erlotinib. PMID- 29183268 TI - Potential natural mTOR inhibitors screened by in silico approach and suppress hepatic stellate cells activation. AB - The mammalian target of rapamycin (mTOR), an atypical serine/threonine kinase, plays a central role in the regulation of cell proliferation, growth, differentiation, migration, and survival. In this study, the 3-D structure of the mTOR (PDB ID: 2FAP) was used for the docking of 47 natural compounds and compared with pharmacophore model of 14 known mTOR inhibitors to identify the novel and specific natural inhibitor. The top four compounds, rutin, curcumin, antroquinonol, and benzyl cinnamate, have been selected based on their PLP score and further validated with hepatic stellate cells NHSC and THSC. Curcumin and antroquinonol significantly inhibited NHSC and THSC cells proliferation in a dose dependent manner, whereas rutin and benzyl cinnamate showed less alteration of cell viability. Rutin inhibited the phosphorylation of mTOR (p-mTOR) and p-p70 S6 K in NHSC and THSC cells by Western blotting. Additionally, p-p70 S6 K protein was significantly decreased by incubation with benzyl cinnamate and curcumin in THSC cells. Taken together, this result suggests that rutin is a potential mTOR inhibitor in screen hits of molecular docking to hamper the activation of HSC and further applications in the treatment of liver fibrosis. PMID- 29183269 TI - High incidence of extra-genital gonorrheal and chlamydial infections among high risk men who have sex with men and transgender women in Peru. AB - Extra-genital Neisseria gonorrhoeae and Chlamydia trachomatis infections are associated with antimicrobial resistance and HIV acquisition. We analyzed data from a cohort of men who have sex with men (MSM) and transgender women followed quarterly for two years in Peru. Incident cases were defined as positive N. gonorrhoeae or C. trachomatis nucleic acid tests during follow-up. Repeat positive tests were defined as reinfection among those with documented treatment. We used generalized estimating equations to calculate adjusted incidence rate ratios (aIRRs). Of 404 participants, 22% were transgender. Incidence rates of rectal N. gonorrhoeae and C. trachomatis infection were 28.1 and 37.3 cases per 100 person-years, respectively. Incidence rates of pharyngeal N. gonorrhoeae and C. trachomatis infection were 21.3 and 9.6 cases per 100 person-years, respectively. Incident HIV infection was associated with incident rectal (aIRR = 2.43; 95% CI 1.66-3.55) N. gonorrhoeae infection. Identifying as transgender versus cisgender MSM was associated with incident pharyngeal N. gonorrhoeae (aIRR = 1.85; 95% CI 1.12-3.07) infection. The incidence of extra-genital N. gonorrhoeae and C. trachomatis infections was high in our population. The association with incident HIV infection warrants evaluating the impact of rectal N. gonorrhoeae screening and treatment on HIV transmission. PMID- 29183270 TI - Results from the post-exposure prophylaxis pilot program (P-QUAD) demonstration project in Los Angeles County. AB - Post-exposure prophylaxis (PEP) is a promising but under-utilized strategy for HIV prevention in high-risk populations. Between March 2010 and June 2011, two community-based clinics in Los Angeles County provided PEP in a pilot program to 267 unique individuals. Courses were primarily dispensed to men who have sex with men (84%) and consisted overwhelmingly of a three-drug antiretroviral therapy regimen containing two nucleoside reverse transcriptase inhibitors and either an integrase inhibitor (raltegravir) or a boosted protease inhibitor (lopinavir/ritonavir). Approximately 64% of all PEP courses were followed for at least 12 weeks, and seven individuals seroconverted. Of the seven seroconversions, six had subsequent re-exposure. The low rate of PEP failure calls for expanded funding for PEP in other jurisdictions. PMID- 29183271 TI - Compulsory licensing of pharmaceuticals reconsidered: Current situation and implications for access to medicines. AB - To examine patterns and trends in attempts, distinguished from issuance, to issue compulsory licensing of pharmaceuticals and to assess related implications in the era of high-cost medicines. Documents from various civil society organisations were primarily used to search attempts, as well as published literature. The identified attempts were analysed by pharmaceutical level, national level, claimers, and the outcomes of the attempts. There have been 108 attempts to issue compulsory licensing for 40 pharmaceuticals in 27 countries since 1995. Most of the attempts were in Asian, Latin American, and African countries and mainly for HIV/AIDS medicines. Moreover, when the claimer was the government, the likelihood of approval and positive outcomes increased. Compulsory licensing, which was devised to cope with the HIV/AIDS pandemic in low-income countries, became a practical measure in several Asian and Latin American countries, even for non HIV/AIDS medicines. Resurgent compulsory licensing in 2012 and 2014, influenced by the global justice movement, might represent a policy window in the near future as the Doha Declaration did in the 2000s. In this context, various experiences should be circulated and analysed at the global level to better understand the circumstances under which successful issuance has been achieved at the country level. PMID- 29183272 TI - Efficacy and safety of additional surgery after non-curative endoscopic submucosal dissection for early colorectal cancer. AB - BACKGROUND: Additional surgery is recommended when early colorectal cancer (ECRC) is resected by non-curative endoscopic submucosal dissection (ESD) and there is significant risk of lymph node metastasis (LNM). The aim of this study was to investigate the efficacy and safety of additional surgery after non-curative ESD for ECRC and evaluate long-term outcomes. METHODS: Patients with ECRC who underwent ESD and additional surgery between July 2007 and November 2013 were identified. Histology and patient data were collected during an average period of more than 5 years to determine tumor stage and type, resection status, complications, tumor recurrence, and distant metastasis. RESULTS: Fifty-one patients who underwent additional surgery were eligible for analysis. Overall, regional LNM was detected in 5 patients (9.8%) and presence of lymphovascular infiltration was a significant risk factor. Surgery-related complications occurred in 3 patients (5.9%). During a median follow-up period of 59 months, no metastasis or local recurrence was observed. Three patients died of other diseases and no CRC-related deaths took place. CONCLUSIONS: Additional surgery after non-curative ESD for ECRC is effective and safe and should be encouraged to foster curative treatment and better long-term outcomes. PMID- 29183273 TI - Impact of the estimation equation for GFR on population-based prevalence estimates of kidney dysfunction. AB - BACKGROUND: Estimating equations are recommended by clinical guidelines as the preferred method for assessment of glomerular filtration rate (GFR). The aim of the study was to compare population-based prevalence estimates of decreased kidney function in Germany defined by an estimated GFR (eGFR) <60 ml/min/1.73m2 using different equations. METHODS: The study included 7001 participants of the German Health Interview and Examination Survey for Adults 2008-2011 (DEGS1) for whom GFR was estimated using the Modification of Diet in Renal Disease study equation (MDRD), the revised Lund-Malmo equation (LM), the Full Age Spectrum creatinine equation (FAScre), the Chronic Kidney Disease Epidemiology Collaboration equations with creatinine and cystatin C (CKD-EPIcrecys), with creatinine (CKD-EPIcre) and with cystatin C (CKD-EPIcys). Bland-Altman plots were used to evaluate the agreement between the equations. RESULTS: Prevalence estimates of decreased kidney function were: 2.1% (CKD-EPIcys), 2.3% (CKD EPIcrecys), 3.8% (CKD-EPIcre), 5.0% (MDRD), 6.0% (LM) and 6.9% (FAScre). The systematic differences between the equations were smaller by comparing either equations that include serum cystatin C or equations that include serum creatinine alone and increased considerably by increasing eGFR. CONCLUSIONS: Prevalence estimates of decreased kidney function vary considerably according to the equation used for estimating GFR. Equations that include serum cystatin C provide lower prevalence estimates if compared with equations based on serum creatinine alone. However, the analysis of the agreement between the equations according to eGFR provides evidence that the equations may be used interchangeably among persons with pronounced decreased kidney function. The study illustrates the implications of the choice of the estimating equation in an epidemiological setting. PMID- 29183274 TI - Mortality trends for accidental falls in older people in Spain, 2000-2015. AB - BACKGROUND: Accidental falls in older people are a major public health problem but a relatively limited number of studies have analyzed the mortality trends from this cause. Effective public health interventions have been found to prevent the incidence of falls and their complications. Therefore, characterizing the mortality trends of falls for different subpopulations can help to identify their needs and contribute to develop more appropriate prevention programs for specific target groups. METHODS: This study was based on a longitudinal analysis of death rates from accidental falls (2000-2015) stratified by sex for the population >= 65 years and by age groups (65-74, 75-84, >=85). A joinpoint regression model was used to identify trend inflection points. The Annual Percent Change (APC) was estimated for each trend. RESULTS: Mortality rates per 100,000 person-years increased from 20.6 to 30.1 for men and 13.8 to 20.8 for women between 2000 and 2015. Men presented a relevant trend increase between 2008 and 2015 (APC [95% CI] 7.2% [5.3;9.2]) and women between 2008 and 2013 (7.9% [4.1;11.8]) There were no trend differences between sexes. For 65-74 years old men we found a relevant increase in the last period (2011-2015) (7.8% [1.0;15.1]). Those aged 75-84 years showed a trend increase between 2007 and 2015 (6.4% [4.4;8.4]) and men >=85 years presented a remarkably high trend between 2008 and 2015 (9.0% [5.2;13]). There were no relevant differences between age groups. Women aged 65-74 had no relevant trend through the period. Those aged 75-84 presented an uniform trend increase for the whole period, 2000-2015, (3.4% [2.3;4.4]) and women >=85 had and important trend increase between 2008 and 2013 (11.1% [5.3;17.2]), that has reached an stable level in the last 2 years. There were no relevant differences between the 75-84 and >=85 age groups. CONCLUSIONS: Recent mortality trends from accidental falls increased in men >=65 years and women >=75 years. These results recommend the implementation of specific preventive programs. PMID- 29183275 TI - Prevalence and associated risk factors of undercorrected refractive errors among people with diabetes in Shanghai. AB - BACKGROUND: To investigate the prevalence and risk factors of undercorrected refractive error (URE) among people with diabetes in the Baoshan District of Shanghai, where data for undercorrected refractive error are limited. METHODS: The study was a population-based survey of 649 persons (aged 60 years or older) with diabetes in Baoshan, Shanghai in 2009. One copy of the questionnaire was completed for each subject. Examinations included a standardized refraction and measurement of presenting and best-corrected visual acuity (BCVA), tonometry, slit lamp biomicroscopy, and fundus photography. RESULTS: The calculated age standardized prevalence rate of URE was 16.63% (95% confidence interval [CI] 13.76-19.49). For visual impairment subjects (presenting vision worse than 20/40 in the better eye), the prevalence of URE was up to 61.11%, and 75.93% of subjects could achieve visual acuity improvement by at least one line using appropriate spectacles. Under multiple logistic regression analysis, older age, female gender, non-farmer, increasing degree of myopia, lens opacities status, diabetic retinopathy (DR), body mass index (BMI) index lower than normal, and poor glycaemic control were associated with higher URE levels. Wearing distance eyeglasses was a protective factor for URE. CONCLUSION: The undercorrected refractive error in diabetic adults was high in Shanghai. Health education and regular refractive assessment are needed for diabetic adults. Persons with diabetes should be more aware that poor vision is often correctable, especially for those with risk factors. PMID- 29183276 TI - The effectiveness of prehospital hypertonic saline for hypotensive trauma patients: a systematic review and meta-analysis. AB - BACKGROUND: The optimal prehospital fluid for the treatment of hypotension is unknown. Hypertonic fluids may increase circulatory volume and mute the pro inflammatory response of the body to injury and illness. The purpose of this systematic review is to determine whether in patients presenting with hypotension in the prehospital setting (population), the administration of hypertonic saline (intervention), compared to an isotonic fluid (control), improves survival to hospital discharge (outcome). METHODS: Searches were conducted in Medline, Embase, CINAHL, and CENTRAL from the date of database inception to November, 2016, and included all languages. Two reviewers independently selected randomized control trials of hypotensive human participants administered hypertonic saline in the prehospital setting. The comparison was isotonic fluid, which included normal saline, and near isotonic fluids such as Ringer's Lactate. Assessment of study quality was done using the Cochrane Collaborations' risk of bias tool and a fixed effect meta-analysis was conducted to determine the pooled relative risk of survival to hospital discharge. Secondary outcomes were reported for fluid requirements, multi-organ failure, adverse events, length of hospital stay, long term survival and disability. RESULTS: Of the 1160 non-duplicate citations screened, thirty-eight articles underwent full-text review, and five trials were included in the systematic review. All studies administered a fixed 250 ml dose of 7.5% hypertonic saline, except one that administered 300 ml. Two studies used normal saline, two Ringer's Lactate, and one Ringer's Acetate as control. Routine care co-interventions included isotonic fluids and colloids. Five studies were included in the meta-analysis (n = 1162 injured patients) with minimal statistical heterogeneity (I 2 = 0%). The pooled relative risk of survival to hospital discharge with hypertonic saline was 1.02 times that of patients who received isotonic fluids (95% Confidence Interval: 0.95, 1.10). There were no consistent statistically significant differences in secondary outcomes. CONCLUSIONS: There was no significant difference in important clinical outcomes for hypotensive injured patients administered hypertonic saline compared to isotonic fluid in the prehospital setting. Hypertonic saline cannot be recommended for use in prehospital clinical practice for the management of hypotensive injured patients based on the available data. PROSPERO registration # CRD42016053385 . PMID- 29183277 TI - Unfavorable impact of cancer cachexia on activity of daily living and need for inpatient care in elderly patients with advanced non-small-cell lung cancer in Japan: a prospective longitudinal observational study. AB - BACKGROUND: Cancer cachexia in elderly patients may substantially impact physical function and medical dependency. The aim of this study was to estimate the impact of cachexia on activity of daily living (ADL), length of hospital stay, and inpatient medical costs among elderly patients with advanced non-small-cell lung cancer (NSCLC) receiving chemotherapy. METHODS: Thirty patients aged >=70 years with advanced NSCLC (stage III-IV) scheduled to receive first-line chemotherapy were prospectively enrolled between January 2013 and November 2014. ADL was assessed using the Barthel index. The disability-free survival time (DFS) was calculated as the time between the date of study entry and the date of onset of a disabling event, which was defined as a 10-point decrease in the Barthel index from that at baseline. The mean cumulative function of the length of hospital stay and inpatient medical costs (Y, Japanese yen) was calculated. RESULTS: The study patients comprised 11 women and 19 men, with a median age of 74 (range, 70 82) years. Cachexia was diagnosed in 19 (63%) patients. Cachectic patients had a shorter DFS (7.5 vs. 17.1 months, p < 0.05). During the first year from study entry, cachectic patients had longer cumulative lengths of hospital stay (80.7 vs. 38.5 days/person, p < 0.05), more frequent unplanned hospital visits or hospitalizations (4.2 vs. 1.7 times/person, p < 0.05), and higher inpatient medical costs (Y3.5 vs. Y2.1 million/person, p < 0.05) than non-cachectic patients. CONCLUSIONS: Elderly NSCLC patients with cachexia showed higher risks for disability, prolonged hospitalizations, and higher inpatient medical costs while receiving chemotherapy than patients without cachexia. Our results might indicate that there is a potential need for an early intervention to minimize progression to or development of cachexia, improve functional prognosis, and reduce healthcare resource burden in this population. TRIAL REGISTRATION: Trial registration number: UMIN000009768 . Name of registry: UMIN (University hospital Medical Information Network). Date of registration: 14 January 2013.

PMID- 29183278 TI - Capnography sensor use is associated with reduction of adverse outcomes during gastrointestinal endoscopic procedures with sedation administration. AB - BACKGROUND: Evidence to date suggests that capnography monitoring during gastrointestinal endoscopic procedures (GEP) reduces the incidence of hypoxemia, but the association of capnography monitoring with the incidence of other adverse outcomes surrounding these procedures has not been well studied. Our aims were to estimate the incidence of pharmacological rescue events and death at discharge from an inpatient or outpatient hospitalization where GEP was performed with sedation, and to determine if capnography monitoring was associated with reduced incidence of these adverse outcomes. METHODS: This retrospective Premier Database analysis included medical inpatients and all outpatients undergoing GEP with sedation. Patients were grouped as follows: (1) pulse oximetry (SpO2) only, (2) capnography only, (3) SpO2 with capnography, and (4) neither SpO2 nor capnography. Multivariable logistic regression and propensity-score matching were used to compare patients with capnography sensor use to patients with only SpO2 sensor use. Outcome measures included the incidence of pharmacological rescue events, as defined by administration of naloxone and/or flumazenil, and death. RESULTS: Two hundred fifty eight thousand and two hundred sixty two inpatients and 3,807,151 outpatients were analyzed. For inpatients, capnography monitoring was associated with a 47% estimated reduction in the odds of death at discharge (OR: 0.53 [95% CI: 0.40-0.70]; P < 0.0001) and a non-significant 10% estimated reduction in the odds of pharmacological rescue event at discharge (0.91 [0.65 1.3]; P = 0.5661). For outpatients, capnography monitoring was associated with a 61% estimated reduction in the odds of pharmacological rescue event at discharge (0.39 [0.29, 0.52]; P < 0.0001) and a non-significant 82% estimated reduction in the odds of death at discharge (0.18 [0.02, 1.99]; P = 0.16). CONCLUSIONS: In hospital medical inpatients and all outpatients undergoing GEP performed with sedation, capnography monitoring was associated with a reduced likelihood of pharmacological rescue events in outpatients and death in inpatients when assessed at discharge. Despite the limitations of the retrospective data analysis methodology, the use of capnography during these procedures is recommended. PMID- 29183279 TI - Panitumumab use in metastatic colorectal cancer and patterns of RAS testing: results from a Europe-wide physician survey and medical records review. AB - BACKGROUND: In Europe, treatment of metastatic colorectal cancer (mCRC) with panitumumab requires prior confirmation of RAS wild-type mutation status. Two studies - a physician survey and a medical records review (MRR) - were conducted to evaluate the use of panitumumab and awareness among prescribing oncologists of the associated RAS testing requirements in clinical practice. METHODS: Both studies enrolled participants from nine European countries and were carried out in three consecutive rounds. Rounds 1 and 2 (2012-2013) examined KRAS (exon 2) testing only; the results have been published in full previously. Round 3 (2014 2015) examined full RAS testing (exons 2, 3, 4 of KRAS and NRAS) and was initiated following a change in prescribing guidelines, from requiring KRAS alone to requiring full RAS testing. For the physician survey, telephone interviews were conducted with oncologists who had prescribed panitumumab to patients with mCRC in the previous 6 months. For the MRR, oncologists were asked to provide anonymised clinical information, extracted from their patients' records. RESULTS: In Round 3, 152 oncologists and 131 patients' records were included in the physician survey and MRR, respectively. In Round 3 of the physician survey, 95.4% (n = 145) of participants correctly identified that panitumumab should only be prescribed in RAS wild-type mCRC compared with 99.0% (n = 298) of 301 participants in Rounds 1 and 2, responding to the same question about KRAS testing. In Round 3 of the MRR, 100% (n = 131) of patients included in the study had confirmed KRAS or RAS wild-type status prior to initiation of panitumumab compared with 97.7% (n = 299) of 306 patients in Rounds 1 and 2 (KRAS only). Of those patients in Round 3, 83.2% (n = 109) had been tested for RAS status and 16.8% (n = 22) had been tested for KRAS status only. CONCLUSIONS: Physicians' adherence to prescribing guidelines has remained high over time in Europe, despite the change in indication for panitumumab treatment, from KRAS to RAS wild type mCRC. Additionally, this study demonstrates the uptake of full RAS testing among the majority of oncologists and pathologists. PMID- 29183280 TI - Using a monitoring and evaluation framework to improve study efficiency and quality during a prospective cohort study in infants receiving rotavirus vaccination in El Alto, Bolivia: the Infant Nutrition, Inflammation, and Diarrheal Illness (NIDI) study. AB - BACKGROUND: Implementing rigorous epidemiologic studies in low-resource settings involves challenges in participant recruitment and follow-up (e.g., mobile populations, distrust), biological sample collection (e.g., cold-chain, laboratory equipment scarcity) and data collection (e.g., literacy, staff training, and infrastructure). This article describes the use of a monitoring and evaluation (M&E) framework to improve study efficiency and quality during participant engagement, and biological sample and data collection in a longitudinal cohort study of Bolivian infants. METHODS: The study occurred between 2013 and 2015 in El Alto, Bolivia, a high-altitude, urban, low-resource community. The study's M&E framework included indicators for participant engagement (e.g., recruitment, retention, safety), biological sample (e.g., stool and blood), and data (e.g., anthropometry, questionnaires) collection and quality. Monitoring indicators were measured regularly throughout the study and used for course correction, communication, and staff retraining. RESULTS: Participant engagement indicators suggested that enrollment objectives were met (461 infants), but 15% loss-to-follow-up resulted in only 364 infants completing the study. Over the course of the study, there were four study-related adverse events (minor swelling and bruising related to a blood draw) and five severe adverse events (infant deaths) not related to study participation. Biological sample indicators demonstrated two blood samples collected from 95% (333 of 350 required) infants and stool collected for 61% of reported infant diarrhea episodes. Anthropometry data quality indicators were extremely high (median SDs for weight-for-length, length-for-age and weight-for-age z-scores 1.01, 0.98, and 1.03, respectively), likely due to extensive training, standardization, and monitoring efforts. CONCLUSIONS: Conducting human subjects research studies in low-resource settings often presents unique logistical difficulties, and collecting high-quality data is often a challenge. Investing in comprehensive M&E is important to improve participant recruitment, retention and safety, and sample and data quality. The M&E framework from this study can be applied to other longitudinal studies. PMID- 29183281 TI - Optimizing and evaluating the reconstruction of Metagenome-assembled microbial genomes. AB - BACKGROUND: Microbiome/host interactions describe characteristics that affect the host's health. Shotgun metagenomics includes sequencing a random subset of the microbiome to analyze its taxonomic and metabolic potential. Reconstruction of DNA fragments into genomes from metagenomes (called metagenome-assembled genomes) assigns unknown fragments to taxa/function and facilitates discovery of novel organisms. Genome reconstruction incorporates sequence assembly and sorting of assembled sequences into bins, characteristic of a genome. However, the microbial community composition, including taxonomic and phylogenetic diversity may influence genome reconstruction. We determine the optimal reconstruction method for four microbiome projects that had variable sequencing platforms (IonTorrent and Illumina), diversity (high or low), and environment (coral reefs and kelp forests), using a set of parameters to select for optimal assembly and binning tools. METHODS: We tested the effects of the assembly and binning processes on population genome reconstruction using 105 marine metagenomes from 4 projects. Reconstructed genomes were obtained from each project using 3 assemblers (IDBA, MetaVelvet, and SPAdes) and 2 binning tools (GroopM and MetaBat). We assessed the efficiency of assemblers using statistics that including contig continuity and contig chimerism and the effectiveness of binning tools using genome completeness and taxonomic identification. RESULTS: We concluded that SPAdes, assembled more contigs (143,718 +/- 124 contigs) of longer length (N50 = 1632 +/- 108 bp), and incorporated the most sequences (sequences-assembled = 19.65%). The microbial richness and evenness were maintained across the assembly, suggesting low contig chimeras. SPAdes assembly was responsive to the biological and technological variations within the project, compared with other assemblers. Among binning tools, we conclude that MetaBat produced bins with less variation in GC content (average standard deviation: 1.49), low species richness (4.91 +/- 0.66), and higher genome completeness (40.92 +/- 1.75) across all projects. MetaBat extracted 115 bins from the 4 projects of which 66 bins were identified as reconstructed metagenome-assembled genomes with sequences belonging to a specific genus. We identified 13 novel genomes, some of which were 100% complete, but show low similarity to genomes within databases. CONCLUSIONS: In conclusion, we present a set of biologically relevant parameters for evaluation to select for optimal assembly and binning tools. For the tools we tested, SPAdes assembler and MetaBat binning tools reconstructed quality metagenome-assembled genomes for the four projects. We also conclude that metagenomes from microbial communities that have high coverage of phylogenetically distinct, and low taxonomic diversity results in highest quality metagenome-assembled genomes. PMID- 29183282 TI - Bilateral muscle fiber and nerve influences by TNF-alpha in response to unilateral muscle overuse - studies on TNF receptor expressions. AB - BACKGROUND: TNF-alpha is suggested to be involved in muscle damage and muscle inflammation (myositis). In order to evaluate whether TNF-alpha is involved in the myositis that occurs in response to muscle overuse, the aim was to examine the expression patterns of TNF receptors in this condition. METHODS: A rabbit muscle overuse model leading to myositis in the soleus muscle was used. The expression patterns of the two TNF receptors Tumor Necrosis Factor Receptor type 1 (TNFR1) and Tumor Necrosis Factor Receptor type 2 (TNFR2) were investigated. In situ hybridization and immunofluorescence were utilized. Immunostainings for desmin, NK-1R and CD31 were made in parallel. RESULTS: Immunoreactions (IR) for TNF receptors were clearly observed in white blood cells, fibroblasts and vessel walls, and most interestingly also in muscle fibers and nerve fascicles in the myositis muscles. There were very restricted reactions for these in the muscles of controls. The upregulation of TNF receptors was for all types of structures seen for both the experimental side and the contralateral nonexperimental side. TNF receptor expressing muscle fibers were present in myositis muscles. They can be related to attempts for reparation/regeneration, as evidenced from results of parallel stainings. Necrotic muscle fibers displayed TNFR1 mRNA and TNFR2 immunoreaction (IR) in the invading white blood cells. In myositis muscles, TNFR1 IR was observed in both axons and Schwann cells while TNFR2 IR was observed in Schwann cells. Such observations were very rarely made for control animals. CONCLUSIONS: The findings suggest that there is a pronounced involvement of TNF alpha in the developing myositis process. Attempts for reparation of the muscle tissue seem to occur via both TNFR1 and TNFR2. As the myositis process also occurs in the nonexperimental side and as TNF receptors are confined to nerve fascicles bilaterally it can be asked whether TNF-alpha is involved in the spreading of the myositis process to the contralateral side via the nervous system. Taken together, the study shows that TNF-alpha is not only associated with the inflammation process but that both the muscular and nervous systems are affected and that this occurs both on experimental and nonexperimental sides. PMID- 29183283 TI - Mitochondrial genome sequencing reveals potential origins of the scabies mite Sarcoptes scabiei infesting two iconic Australian marsupials. AB - BACKGROUND: Debilitating skin infestations caused by the mite, Sarcoptes scabiei, have a profound impact on human and animal health globally. In Australia, this impact is evident across different segments of Australian society, with a growing recognition that it can contribute to rapid declines of native Australian marsupials. Cross-host transmission has been suggested to play a significant role in the epidemiology and origin of mite infestations in different species but a chronic lack of genetic resources has made further inferences difficult. To investigate the origins and molecular epidemiology of S. scabiei in Australian wildlife, we sequenced the mitochondrial genomes of S. scabiei from diseased wombats (Vombatus ursinus) and koalas (Phascolarctos cinereus) spanning New South Wales, Victoria and Tasmania, and compared them with the recently sequenced mitochondrial genome sequences of S. scabiei from humans. RESULTS: We found unique S. scabiei haplotypes among individual wombat and koala hosts with high sequence similarity (99.1% - 100%). Phylogenetic analysis of near full-length mitochondrial genomes revealed three clades of S. scabiei (one human and two marsupial), with no apparent geographic or host species pattern, suggestive of multiple introductions. The availability of additional mitochondrial gene sequences also enabled a re-evaluation of a range of putative molecular markers of S. scabiei, revealing that cox1 is the most informative gene for molecular epidemiological investigations. Utilising this gene target, we provide additional evidence to support cross-host transmission between different animal hosts. CONCLUSIONS: Our results suggest a history of parasite invasion through colonisation of Australia from hosts across the globe and the potential for cross host transmission being a common feature of the epidemiology of this neglected pathogen. If this is the case, comparable patterns may exist elsewhere in the 'New World'. This work provides a basis for expanded molecular studies into mange epidemiology in humans and animals in Australia and other geographic regions. PMID- 29183284 TI - Robust expression of tumor suppressor miRNA's let-7 and miR-195 detected in plasma of Saudi female breast cancer patients. AB - BACKGROUND: Female breast cancer is frequently diagnosed at a later stage and the leading cause of cancer deaths world-wide. Levels of cell-free circulating microRNAs (miRNAs) can potentially be used as biomarkers to measure disease progression in breast cancer patients in a non-invasive way and are therefore of high clinical value. METHODS: Using quantitative RT-PCR, circulating miRNAs were measured in blood samples collected from disease-free individuals (n = 34), triple-negative breast tumours (TNBC) (n = 36) and luminal tumours (n = 57). In addition to intergroup comparisons, plasma miRNA expression levels of all groups were analyzed against RNASeq data from cancerous breast tissue via The Cancer Genome Atlas (TCGA). RESULTS: A differential set of 18 miRNAs were identified in the plasma of breast cancer patients and 10 miRNAs were uniquely identified based on ROC analysis. The most striking findings revealed elevated tumor suppressor let-7 miRNA in luminal breast cancer patients, irrespective of subtype, and elevated miR-195 in plasma of TNBC breast cancer patients. In contrast, hsa-miR 195 and let-7 miRNAs were absent from cancerous TCGA tissue and strongly expressed in surrounding non-tumor tissue indicating that cancerous cells may selectively export tumor suppressor hsa-miR-195 and let-7 miRNAs in order to maintain oncogenesis. CONCLUSIONS: While studies have indicated that the restoration of let-7 and miR-195 may be a potential therapy for cancer, these results suggested that tumor cells may selectively export hsa-miR-195 and let-7 miRNAs thereby neutralizing their potential therapeutic effect. However, in order to facilitate earlier detection of breast cancer, blood based screening of hsa miR-195 and let-7 may be beneficial in a female patient cohort. PMID- 29183285 TI - The German version of the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL 5): psychometric properties and diagnostic utility. AB - BACKGROUND: The Posttraumatic Stress Disorder (PTSD) Checklist (PCL, now PCL-5) has recently been revised to reflect the new diagnostic criteria of the disorder. METHODS: A clinical sample of trauma-exposed individuals (N = 352) was assessed with the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) and the PCL-5. Internal consistencies and test-retest reliability were computed. To investigate diagnostic accuracy, we calculated receiver operating curves. Confirmatory factor analyses (CFA) were performed to analyze the structural validity. RESULTS: Results showed high internal consistency (alpha = .95), high test-retest reliability (r = .91) and a high correlation with the total severity score of the CAPS-5, r = .77. In addition, the recommended cutoff of 33 on the PCL-5 showed high diagnostic accuracy when compared to the diagnosis established by the CAPS 5. CFAs comparing the DSM-5 model with alternative models (the three-factor solution, the dysphoria, anhedonia, externalizing behavior and hybrid model) to account for the structural validity of the PCL-5 remained inconclusive. CONCLUSIONS: Overall, the findings show that the German PCL-5 is a reliable instrument with good diagnostic accuracy. However, more research evaluating the underlying factor structure is needed. PMID- 29183286 TI - First gene-ontology enrichment analysis based on bacterial coregenome variants: insights into adaptations of Salmonella serovars to mammalian- and avian-hosts. AB - BACKGROUND: Many of the bacterial genomic studies exploring evolution processes of the host adaptation focus on the accessory genome describing how the gains and losses of genes can explain the colonization of new habitats. Consequently, we developed a new approach focusing on the coregenome in order to describe the host adaptation of Salmonella serovars. METHODS: In the present work, we propose bioinformatic tools allowing (i) robust phylogenetic inference based on SNPs and recombination events, (ii) identification of fixed SNPs and InDels distinguishing homoplastic and non-homoplastic coregenome variants, and (iii) gene-ontology enrichment analyses to describe metabolic processes involved in adaptation of Salmonella enterica subsp. enterica to mammalian- (S. Dublin), multi- (S. Enteritidis), and avian- (S. Pullorum and S. Gallinarum) hosts. RESULTS: The 'VARCall' workflow produced a robust phylogenetic inference confirming that the monophyletic clade S. Dublin diverged from the polyphyletic clade S. Enteritidis which includes the divergent clades S. Pullorum and S. Gallinarum (i). The scripts 'phyloFixedVar' and 'FixedVar' detected non-synonymous and non homoplastic fixed variants supporting the phylogenetic reconstruction (ii). The scripts 'GetGOxML' and 'EveryGO' identified representative metabolic pathways related to host adaptation using the first gene-ontology enrichment analysis based on bacterial coregenome variants (iii). CONCLUSIONS: We propose in the present manuscript a new coregenome approach coupling identification of fixed SNPs and InDels with regards to inferred phylogenetic clades, and gene-ontology enrichment analysis in order to describe the adaptation of Salmonella serovars Dublin (i.e. mammalian-hosts), Enteritidis (i.e. multi-hosts), Pullorum (i.e. avian-hosts) and Gallinarum (i.e. avian-hosts) at the coregenome scale. All these polyvalent Bioinformatic tools can be applied on other bacterial genus without additional developments. PMID- 29183287 TI - HIV and hepatitis B and C co-infection among people who inject drugs in Zanzibar. AB - BACKGROUND: People who inject drugs are at high risk of acquiring hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV) due to risky injection and sexual practices. The objective of this study is to investigate the epidemiology of HIV, hepatitis B, and hepatitis C, and co-infection of these viruses among people who inject drugs in Zanzibar, Tanzania. METHODS: We used respondent-driven sampling to identify 408 participants, from whom we collected demographic data, information on sexual behaviours and injection drug practices, and blood samples for biological testing. RESULTS: Prevalence of hepatitis B surface antigenaemia, HCV, and HIV infection were 5.9, 25.4, and 11.3%, respectively. Of the participants who were hepatitis B surface antigen (HBsAg) positive, 33.5% were infected with HCV and 18.8% were infected with HIV. Of the HCV-infected participants, 29.3% were infected with HIV. Of the participants who were infected with HIV, 9.0% were HBsAg positive, 66.6% had HCV and 8.5% had both. None of the potential risk factors we measured were associated with HBsAg positivity. In contrast, older age and longer duration of injection drug use were independently associated with HCV infection. HCV infection among people who inject drugs is lower in Zanzibar than in other countries, but could rise without proper interventions. CONCLUSIONS: These findings underscore the importance of screening people who inject drugs for HIV, HBsAg, and HCV; providing HBV vaccination to those who are eligible; initiating antiretroviral therapy for those who are co-infected with HIV/HBV and HIV/HCV; and introducing interventions that have high impact on reducing needle sharing. PMID- 29183288 TI - Arginase 1 deletion in myeloid cells affects the inflammatory response in allergic asthma, but not lung mechanics, in female mice. AB - BACKGROUND: (Over-)expression of arginase may limit local availability of arginine for nitric oxide synthesis. We investigated the significance of arginase1 (ARG1) for the development of airway hyperresponsiveness (AHR) and lung inflammation in female mice with ovalbumin (OVA)-induced allergic asthma. METHODS: Arg1 was ablated in the lung by crossing Arg1 fl/fl and Tie2Cre tg/- mice. OVA sensitization and challenge were conducted, and AHR to methacholine was determined using the Flexivent system. Changes in gene expression, chemokine and cytokine secretion, plasma IgE, and lung histology were quantified using RT-qPCR, ELISA, and immunohistochemistry, respectively. RESULTS: Arg1 ablation had no influence on the development of OVA-induced AHR, but attenuated OVA-induced increases in expression of Arg2 and Nos2, Slc7a1, Slc7a2, and Slc7a7 (arginine transporters), Il4, Il5 and Il13 (TH2-type cytokines), Ccl2 and Ccl11 (chemokines), Ifng (TH1-type cytokine), Clca3 and Muc5ac (goblet cell markers), and OVA-specific IgE. Pulmonary IL-10 protein content increased, but IL-4, IL-5, IL-13, TNFalpha and IFNgamma content, and lung histopathology, were not affected. Arg1 elimination also decreased number and tightness of correlations between adaptive changes in lung function and inflammatory parameters in OVA/OVA-treated female mice. OVA/OVA-treated female mice mounted a higher OVA-IgE response than males, but the correlation between lung function and inflammation was lower. Arg1 deficient OVA/OVA-treated females differed from males in a more pronounced decline of arginine-metabolizing and -transporting genes, higher plasma arginine levels, a smaller OVA-specific IgE response, and no improvement of peripheral lung function. CONCLUSION: Complete ablation of Arg1 in the lung affects mRNA abundance of arginine-transporting and -metabolizing genes, and pro-inflammatory genes, but not methacholine responsiveness or accumulation of inflammatory cells. PMID- 29183289 TI - Youth experiences of transition from child mental health services to adult mental health services: a qualitative thematic synthesis. AB - BACKGROUND: Adolescence and young adulthood is a vulnerable time during which young people experience many development milestones, as well as an increased incidence of mental illness. During this time, youth also transition between Child and Adolescent Mental Health Services (CAMHS) to Adult Mental Health Services (AMHS). This transition puts many youth at risk of disengagement from service use; however, our understanding of this transition from the perspective of youth is limited. This systematic review aims to provide a more comprehensive understanding of youth experiences of transition from CAMHS to AMHS, through a qualitative thematic synthesis of the extant literature in this area. METHOD: Published and unpublished literature was searched using keywords targeting three subject areas: Transition, Age and Mental Health. Studies were included if they qualitatively explored the perceptions and experiences of youth who received mental health services in both CAMHS and AMHS. There were no limitations on diagnosis or age of youth. Studies examining youth with chronic physical health conditions were excluded. RESULTS: Eighteen studies, representing 14 datasets and the experiences of 253 unique service-users were included. Youth experiences of moving from CAMHS and AMHS are influenced by concurrent life transitions and their individual preferences regarding autonomy and independence. Youth identified preparation, flexible transition timing, individualized transition plans, and informational continuity as positive factors during transition. Youth also valued joint working and relational continuity between CAMHS and AMHS. CONCLUSIONS: Youth experience a dramatic culture shift between CAMHS and AMHS, which can be mitigated by individualized and flexible approaches to transition. Youth have valuable perspectives to guide the intelligent design of mental health services and their perspectives should be used to inform tools to evaluate and incorporate youth perspectives into transitional service improvement.

PMID- 29183290 TI - Modeling, validation and verification of three-dimensional cell-scaffold contacts from terabyte-sized images. AB - BACKGROUND: Cell-scaffold contact measurements are derived from pairs of co registered volumetric fluorescent confocal laser scanning microscopy (CLSM) images (z-stacks) of stained cells and three types of scaffolds (i.e., spun coat, large microfiber, and medium microfiber). Our analysis of the acquired terabyte sized collection is motivated by the need to understand the nature of the shape dimensionality (1D vs 2D vs 3D) of cell-scaffold interactions relevant to tissue engineers that grow cells on biomaterial scaffolds. RESULTS: We designed five statistical and three geometrical contact models, and then down-selected them to one from each category using a validation approach based on physically orthogonal measurements to CLSM. The two selected models were applied to 414 z-stacks with three scaffold types and all contact results were visually verified. A planar geometrical model for the spun coat scaffold type was validated from atomic force microscopy images by computing surface roughness of 52.35 nm +/-31.76 nm which was 2 to 8 times smaller than the CLSM resolution. A cylindrical model for fiber scaffolds was validated from multi-view 2D scanning electron microscopy (SEM) images. The fiber scaffold segmentation error was assessed by comparing fiber diameters from SEM and CLSM to be between 0.46% to 3.8% of the SEM reference values. For contact verification, we constructed a web-based visual verification system with 414 pairs of images with cells and their segmentation results, and with 4968 movies with animated cell, scaffold, and contact overlays. Based on visual verification by three experts, we report the accuracy of cell segmentation to be 96.4% with 94.3% precision, and the accuracy of cell-scaffold contact for a statistical model to be 62.6% with 76.7% precision and for a geometrical model to be 93.5% with 87.6% precision. CONCLUSIONS: The novelty of our approach lies in (1) representing cell-scaffold contact sites with statistical intensity and geometrical shape models, (2) designing a methodology for validating 3D geometrical contact models and (3) devising a mechanism for visual verification of hundreds of 3D measurements. The raw and processed data are publicly available from https://isg.nist.gov/deepzoomweb/data/ together with the web -based verification system. PMID- 29183291 TI - Optimization of the Hockey Fans in Training (Hockey FIT) weight loss and healthy lifestyle program for male hockey fans. AB - BACKGROUND: The health outcomes of men continue to be poorer than women globally. Challenges in addressing this problem include difficulties engaging men in weight loss programs as they tend to view these programs as contrary to the masculine narrative of independence and self-reliance. Researchers have been turning towards sports fans to engage men in health promotion programs as sports fans are typically male, and tend to have poor health habits. METHODS: Developed from the highly successful gender-sensitized Football Fans in Training program, Hockey Fans in Training (Hockey FIT) recruited 80 male hockey fans of the London Knights and Sarnia Sting who were overweight or obese into a weekly, 90-minute classroom education and group exercise program held over 12 weeks; a 40-week minimally supported phase followed. A process evaluation of the Hockey FIT program was completed alongside a pragmatic randomized controlled trial and outcome evaluation in order to fully explore the acceptability of the Hockey FIT program from the perspectives of coaches delivering and participants engaged in the program. Data sources included attendance records, participant focus groups, coach interviews, assessment of fidelity (program observations and post-session coach reflections), and 12-month participant interviews. RESULTS: Coaches enjoyed delivering the program and found it simple to deliver. Men valued being among others of similar body shape and similar weight loss goals, and found the knowledge they gained through the program helped them to make and maintain health behaviour changes. Suggested improvements include having more hockey-related information and activities, greater flexibility with timing of program delivery, and greater promotion of technology support tools. CONCLUSIONS: We confirmed Hockey FIT was an acceptable "gender-sensitized" health promotion program for male hockey fans who were overweight or obese. Minor changes were required for optimization, which will be evaluated in a future definitive trial. TRIAL REGISTRATION: NCT02396524 (Clinicaltrials.gov). Date of registration: Feb 26, 2015. PMID- 29183292 TI - Assessment of macular function in patients with idiopathic Epiretinal membrane by multifocal Electroretinography: correlation with visual acuity and optical coherence tomography. AB - BACKGROUND: This study evaluates the macular function changes in patients with idiopathic macular epiretinal membrane (ERM) by multifocal electroretinography (mfERG) and their correlations with visual acuity and central macular thickness (CMT) by optical coherence tomography (OCT). METHODS: Twenty eyes of 20 patients with ERM underwent OCT and mfERG examinations. The response amplitude densities and implicit times of mfERG were compared to the control fellow eyes. Correlation analyses among visual acuity, central macular thickness and mfERG values in the central two concentric rings were performed. RESULTS: The mfERG P1 response amplitude densities in ring 1-2 and P1 implicit time in ring1 were significantly changed in epiretinal membrane eyes compared with controls (P < 0.05). Multivariate stepwise linear regression analyses showed LogMAR visual acuity was significantly correlated with CMT (P = 0.004), and also with the P1 amplitude density in ring 1 (P = 0.002). CMT showed significant correlation with P1 implicit time in ring 2 (P = 0.013). CONCLUSIONS: The mfERG abnormalities show macular function changes and correlate with visual acuity and central macular thickness in eyes with ERM. In first-order mfERG responses, P1 wave changes may be a sensitive functional measurement for ERM patients. PMID- 29183293 TI - Prescribing patterns of rural family physicians: a study in Kermanshah Province, Iran. AB - BACKGROUND: The inappropriate use of drugs due to irrational prescriptions is a common problem in Iran, but there is little evidence of prescription patterns in rural family physicians. This study aimed to explore the prescribing pattern and rational drug use indicators for family physicians using Index of Rational Drug Prescribing (IRDP) in Kermanshah Province, Iran. METHODS: In this retrospective study, 352,399 prescriptions from 184 family physicians in 103 primary health care (PHC) centers were examined. As stated, an analysis was done for rational use indicators suggested by World Health Organization (WHO): e.g., the percentage of prescriptions containing antibiotics, injections, and those prescribed by a generic name and from a national essential medicine list, plus the average number of drugs per prescription; these factors were all taken into account. Rational drug use was studied with the IRDP. RESULTS: The average number of drugs per prescription was 3.14 (+/- 1.2) and the average cost per prescription was 116,740 IRR (USD 3.6). Around 19% of prescriptions had more than four drugs, while the percentage of prescriptions involving antibiotics and injections was 52.1% and 24.4%, respectively. There was 95.1% drugs prescribed by their generic name and 95.9% were retrieved from the essential drugs list. The value of the IRDP was 3.70 out of 5. CONCLUSION: The findings of this study showed that some degree of irrational drug prescribing exists among family physicians, especially in terms of injections, antibiotics, and polypharmacy. It is recommended that there be continuing education programs for physicians regarding rational prescribing for different kinds of medical indications. Clinical practice guidelines should also assist with the rational use of medicine. PMID- 29183294 TI - Serum albumin level as a potential marker for deciding chemotherapy or best supportive care in elderly, advanced non-small cell lung cancer patients with poor performance status. AB - BACKGROUND: There have been few data on the chemotherapy in elderly advanced non small cell lung cancer (NSCLC) patients with poor performance status (PS), and usefulness of chemotherapy for such patients remains unclear. The objective of this study was to identify factors that predicted the survival benefit of chemotherapy. METHODS: All consecutive elderly patients (>=75 years) with advanced NSCLC, Eastern Cooperative Oncology Group PS >=2, EGFR mutation wild type/unknown, and newly diagnosed from January 2009 to December 2012 at a tertiary hospital were retrospectively reviewed. RESULTS: We enrolled 59 patients, and 31 patients received at least one chemotherapy regimen (chemotherapy group). However, 28 patients received best supportive care (BSC) alone (BSC group). The proportion of PS 2 and serum albumin levels was significantly higher in the chemotherapy group than in the BSC group. In the chemotherapy group, log-rank testing did not show statistically significant differences in overall survival (OS) between the single-agent therapy group and carboplatin-based doublet therapy group; however, the OS of patients receiving chemotherapy for only 1 cycle (early termination) was significantly shorter than patients receiving chemotherapy for >=2 cycles. Hypoalbuminemia was not only a risk factor for the early termination of chemotherapy but also an independent prognostic factor in the chemotherapy group. A receiver operating characteristic curve analysis showed that the best cut-off value was 3.40 g/dL. In patients with serum albumin levels >=3.40 g/dL, OS was significantly better in the chemotherapy group than in the BSC group (p = 0.0156), however, patients with serum albumin levels <3.40 g/dL exhibited poor prognosis regardless of the presence or absence of chemotherapy. CONCLUSION: In the elderly NSCLC patients with poor PS, serum albumin levels may help identify certain patient populations more likely to receive a survival benefit of systemic chemotherapy. PMID- 29183295 TI - VDJ gene usage among B-cell receptors in ABO-incompatible kidney transplantation determined by RNA-seq Transcriptomic analysis. AB - BACKGROUND: Studies on B-cell subtypes and V(D)J gene usage of B-cell receptors in kidney transplants are scarce. This study aimed to investigate V(D)J gene segment usage in ABO-incompatible (ABOi) kidney transplant (KT) patients compared to that in ABO-compatible (ABOc) KT patients. METHODS: We selected 16 ABOi KT patients with accommodation (ABOiA), 6 ABOc stable KT patients (ABOcS), and 6 ABOi KT patients with biopsy-proven acute antibody-mediated rejection (ABOiR) at day 10, whose graft tissue samples had been stored in the biorepository between 2010 and 2014. Complete transcriptomes of graft tissues were sequenced and analyzed through RNA sequencing (RNA-seq). The international ImMunoGeneTics information system (IMGT(r)) was used for in-depth comparison of V(D)J gene segment usage. RESULTS: The mean age of the 28 KT recipients was 43.3 +/- 12.8 years, and 53.6% were male. By family, IGHV3, IGHJ4, IGLV2, and IGLJ3 gene segments were most frequently used in all groups, and their usage was not statistically different among the three patient groups. While IGKV3 was most frequently used in both the ABOiA and ABOiR groups, IGKV1 was most commonly used in the ABOcS group. In addition, while IGKJ1 was most commonly used in the ABOiA and ABOcS groups, IGKJ4 was most frequently used in the ABOiR group. According to individual gene segments, IGHV4-34 and IGHV4-30-2 were more commonly used in the ABOiR group than in the ABOiA group, and IGHV6-1 was more commonly used in the ABOcS group than in the ABOiR group. IGLV7-43 was more commonly used in the ABOcS group than in the ABOi group. However, technical variability, small sample size, and potential confounding effects of Rituximab or HLA mismatching are limitations of our study. CONCLUSIONS: Our findings suggest that RNA-seq transcriptomic analyses can provide information on the V(D)J gene usage of B-cell receptors and the mechanisms of accommodation and immune reaction in ABOi KT. PMID- 29183296 TI - Theories, models and frameworks used in capacity building interventions relevant to public health: a systematic review. AB - BACKGROUND: There is limited research on capacity building interventions that include theoretical foundations. The purpose of this systematic review is to identify underlying theories, models and frameworks used to support capacity building interventions relevant to public health practice. The aim is to inform and improve capacity building practices and services offered by public health organizations. METHODS: Four search strategies were used: 1) electronic database searching; 2) reference lists of included papers; 3) key informant consultation; and 4) grey literature searching. Inclusion and exclusion criteria are outlined with included papers focusing on capacity building, learning plans, professional development plans in combination with tools, resources, processes, procedures, steps, model, framework, guideline, described in a public health or healthcare setting, or non-government, government, or community organizations as they relate to healthcare, and explicitly or implicitly mention a theory, model and/or framework that grounds the type of capacity building approach developed. Quality assessment were performed on all included articles. Data analysis included a process for synthesizing, analyzing and presenting descriptive summaries, categorizing theoretical foundations according to which theory, model and/or framework was used and whether or not the theory, model or framework was implied or explicitly identified. RESULTS: Nineteen articles were included in this review. A total of 28 theories, models and frameworks were identified. Of this number, two theories (Diffusion of Innovations and Transformational Learning), two models (Ecological and Interactive Systems Framework for Dissemination and Implementation) and one framework (Bloom's Taxonomy of Learning) were identified as the most frequently cited. CONCLUSIONS: This review identifies specific theories, models and frameworks to support capacity building interventions relevant to public health organizations. It provides public health practitioners with a menu of potentially usable theories, models and frameworks to support capacity building efforts. The findings also support the need for the use of theories, models or frameworks to be intentional, explicitly identified, referenced and for it to be clearly outlined how they were applied to the capacity building intervention. PMID- 29183297 TI - Predictors of early adulthood hypertension during adolescence: a population-based cohort study. AB - BACKGROUND: Some longitudinal studies have shown that blood pressure tracks from adolescence to adulthood, yet there is limited evidence regarding the predictive factors of adulthood hypertension during adolescence. This study was conducted within the framework of the Tehran Lipid and Glucose Study (TLGS) to investigate the role of some factors in adolescence, measured in the first examination (1999 2001), to predict adulthood hypertension in the 4th examination (2009-2011). METHODS: Overall, 1579 subjects, aged 10-19 years, were used for the analysis of the current study. Mean age (SD) of participants at the baseline was 14.2 (2.5) years and 55% of them were female. A forward stepwise approach (p-value <0.2 for enter and >0.05 for removal) was considered to keep significant covariates among common variables including gender, body mass index, waist circumference, wrist and hip circumferences, fasting blood sugar, triglycerides, high density lipoprotein cholesterol, total cholesterol (TC), systolic (SBP) and diastolic blood pressure (DBP). Variance inflation factor (VIF) showed some multicollinearity for anthropometric variables (VIFs between 3.5 and 10). Multivariable logistic regression revealed that gender, blood pressure, wrist circumference and total cholesterol in adolescents are important predictors for adulthood hypertension. RESULTS: The risk increased by 4% and 39% per each 10 mmHg and 1 mmol/L increase in SBP/DBP and TC, respectively; additionally, females had a 70% lower risk. Among anthropometric variables, wrist circumference remained in the model, with 50% per centimeter increase in the risk of hypertension. CONCLUSIONS: Wrist circumferences and TC had significant roles in predicting hypertension through adolescence to adulthood.

AB - BACKGROUND: The purpose of this study was to identify differences in clinical corneal findings after standard and accelerated epithelial off cross-linking (CXL) during a long-term follow-up. METHODS: Two hundred forty-one patients (184 male) were included in this monocentric, retrospective, non-randomized and unmasked study. One hundred forty-eight eyes were treated with the accelerated protocol and 138 with the standard protocol with epithelial off CXL, if diagnosed with keratoconus and a progression in Kmax of more than one dioptre during the preceding 6 months, plus a minimal pachymetry measurement of 400 MUm in keratometry (Pentacam, Oculus GmbH, Wetzlar, Germany). Exclusion criteria were previous surgery, other corneal conditions or age above 50 years. Follow-up time was 36 months with clinical examination and keratometry at every visit. Outcome measures were the observed rate of corneal changes, differences between treatment groups and correlation with keratometry measurements. RESULTS: In patients with accelerated CXL, significantly more clear corneas were seen at three (p = 0.015) and six (p = 0.002) months after surgery than following the standard protocol. The rate of clear corneas dropped from 52.2% pre-operation (OP) to a minimum of 19.3% after 6 months in the standard protocol group compared with 50.7% clear corneas pre-OP and a minimum of 40.8% in the accelerated group. In the standard protocol group, more striae were found 3 months after intervention than in the accelerated group (p = 0.05). CONCLUSIONS: In patients with accelerated CXL, fewer morphological corneal changes were observed than after conventional CXL. However, rarely, corneal changes persisted for a long time. PMID- 29183299 TI - Tobacco-smoking induced GPR15-expressing T cells in blood do not indicate pulmonary damage. AB - BACKGROUND: Recently, it was shown that chronic tobacco smoking evokes specific cellular and molecular changes in white blood cells by an excess of G protein coupled receptor 15 (GPR15)-expressing T cells as well as a hypomethylation at DNA CpG site cg05575921 in granulocytes. In the present study, we aimed to clarify the general usefulness of these two biomarkers as putative signs of non cancerous change in homeostasis of the lungs. METHODS: In a clinical cohort consisting of 42 patients with chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD) and pneumonia and a control cohort of 123 volunteers, the content of GPR15-expressing blood cells as well as the degree of methylation at cg05575921 were analysed by flow-cytometry and pyrosequencing, respectively. Smoking behaviour was estimated by questionnaire and cotinine level in plasma. RESULTS: Never-smoking patients could be distinguished from former and current smokers by both the proportion of GPR15-expressing T cells as well as cg05575921 methylation in granulocytes, with 100% and 97% specificity and 100% sensitivity, respectively. However, both parameters were not affected by lung diseases. The degrees of both parameters were not changed neither in non-smoking nor smoking patients, compared to appropriate control cohorts of volunteers. CONCLUSIONS: The degree of GPR15-expressing cells among T cells as well as the methylation at cg05575921 in granulocytes in blood are both rather signs of tobacco-smoking induced systemic inflammation because they don't indicate specifically non-cancerous pathological changes in the lungs. PMID- 29183300 TI - Metabolic syndrome and its components among university students in Kenya. AB - BACKGROUND: Metabolic syndrome refers to a cluster of interrelated disorders which occur together causing an increase in the risk of developing cardiovascular disease and diabetes. The university population is an understudied group despite the increase in the frequency of related disorders and metabolic risk factors e.g. obesity and diabetes, majorly due to the assumption that they are in their most active phase of life therefore healthy. This study looked at metabolic syndrome, the sedentary lifestyles and dietary habits present among university students attending Mount Kenya University, main campus. METHODS: Stratified sampling was used to select participants. Self-administered questionnaires were issued to participants after a signed consent had been obtained following which clinical assessments and biochemical measures were performed. They included blood pressure, fasting blood glucose, triglycerides, high density lipoprotein cholesterol, anthropometric measurements; height, weight, BMI and waist circumference. Pearson's chi-square tests and non-parametric independent t-test were used to analyze the prevalence of metabolic syndrome criteria per gender, the number of metabolic syndrome criteria per BMI and prevalence of metabolic syndrome criteria per BMI category. RESULTS: The study established that 1.9% of the participants met the criteria for diagnosis of metabolic syndrome according to HJSS criteria. Among the elements, there was statistical difference in gender BMI and waist circumference. 11.8% of subjects had two metabolic syndrome components while 3.1% had three components while none of the subjects had all six components. Elevated triglycerides was the most prevalent defining component for metabolic syndrome. There is a statistically significant relationship between sedentary lifestyle and dietary habits as risk factors to metabolic syndrome. CONCLUSION: Young adults in university have begun developing metabolic syndrome and the risk of developing the syndrome continues to increase with the components being reported in early age. Educational initiatives to encourage healthy eating should be conducted within school premises in order to reinforce the message on healthy diets and physical exercise. Pre-admission screening to identify at risk students should be conducted. Targeted interventions development through a mandatory extra co-curricular program should be enforced to positively engage those at risk. PMID- 29183301 TI - Consistent condom use and its correlates among female sex workers at hair salons: a cross-sectional study in Zhejiang province, China. AB - BACKGROUND: This study investigated condom use among female sex workers (FSWs) at hair salons during commercial sexual interactions over 1 month. We explored the associations of such use with various sexual behaviours, HIV/STI risk perception and related knowledge, self-efficacy regarding condom use, exposure to behavioural interventions, and other factors. This type of information has not been reported in China and is critical for designing and modifying programs aimed at preventing HIV/STI transmission in this group of FSWs and their clients. METHODS: Our data were derived from a large cross-sectional study conducted among low-tier FSWs in 21 counties within Zhejiang province, China. Data were collected from September to November 2013.Bivariable and multiple logistic regression analyses were used to identify factors associated with self-reported consistent condom use among FSWs working at hair salons. RESULTS: Of 1682 FSWs working at hair salons, 50.5% consistently used condom with clients during the previous month. Multivariable analysis revealed that condom use for commercial sex, consistent vaginal douching after commercial sex, adopting contraceptive measures, high scores on perceived self-efficacy regarding condom use, and exposure to interventions were associated with self-reported consistent condom use; early initiation of commercial sex, experiences with oral sex, rarely/sometimes/often using oral contraceptives, and having seen a doctor were associated with not using condoms. CONCLUSIONS: Commercial sex is not effectively protected, and behavioural interventions targeting FSWs should take into account the various factors that are correlated to condom use. PMID- 29183302 TI - Individual, social and environmental determinants of smokeless tobacco and betel quid use amongst adolescents of Karachi: a school-based cross-sectional survey. AB - BACKGROUND: With 600 million people using betel quid (BQ) globally, and smokeless tobacco (SLT) use being more wide-spread; the duo is an uphill public health concern in South Asian countries. SLT and/or BQ use increases the risk for morbidity and mortality from oral cancer. Because SLT and/or BQ use is initiated during adolescence, it renders this group more vulnerable; and particular attention is needed to curb SLT and/or BQ use to reduce related disease burden. We aimed to observe the differential individual, social and environmental features amongst SLT and/or BQ users to determine the key influencers of its use in adolescents. METHODS: This study was a cross-sectional survey of 2140 adolescents from secondary schools of Karachi, Pakistan. The main outcome measure was SLT and/or BQ use based on their consumption in the past 30 days. Univariate and multivariate regression binary logistic analyses were employed while reporting results in both crude form and adjusted odds ratio (after adjusting for all remaining individual, social and environmental level variables) with 95% confidence level. A p-value of < .05 was considered significant for all analyses. RESULTS: The overall prevalence of SLT and/or BQ use was 42.6% (n = 912) of the total sample. The SLT and/or BQ consumer group had more males than females. A significant proportion of user (n = 558, 61.2%) was found in co-education schools. Students whose peers (OR = 6.79, 95% CI 4.67-9.87, p-value <0.001) and/or either of the parents (OR = 2.16, 95% CI 1.73-2.65, p-value <0.001) used SLT and/or BQ, alongside, adolescents who had not attended knowledge based sessions in schools regarding harmful effects of SLT and/or BQ were more likely to consume it. It's availability with outside school hawkers increased the odds of its use by 6 times, as indicated by both univariate and multivariate models after adjusting for the remaining variables. CONCLUSION: In conclusion, students studying in co-education, parents and peers use, lack of knowledge based sessions on harmful health effects of SLT and/or BQ, and easy availability of the product from hawkers outside school all contribute towards enhanced risk of SLT and/or BQ use in adolescents. PMID- 29183303 TI - Link between neurodegeneration and trabecular meshwork injury in glaucomatous patients. AB - BACKGROUND: Glaucoma is classified as a neurodegenerative disease. However, the biomarkers of neurodegeneration in the aqueous humour of primary open angle glaucoma (POAG) eyes have not been quantitatively examined yet. In this study, levels of neurodegeneration-related cytokines in the aqueous humour of POAG eyes were measured and compared with those of non-glaucoma (senile cataract) control eyes. METHODS: This cross-sectional study included 24 patients (24 eyes) with POAG and 22 patients (22 eyes) with cataract. Aqueous humour samples were collected before the commencement of phacoemulsification surgery. The concentrations of brain-derived neurotrophic factor (BDNF), cathepsin D, myeloperoxidase (MPO), soluble intercellular adhesion molecule-1 (sICAM-1), soluble neural cell adhesion molecule (sNCAM), soluble vascular cell adhesion molecule-1 (sVCAM-1), and plasminogen activator inhibitor-1 (PAI-1) were measured using the Luminex suspension array technique. The clinical characteristics of the patients were also obtained for correlation analysis. RESULTS: Compared with the cataract group, the levels of cathepsin D (P < 0.001), sNCAM (P < 0.001) and sVCAM-1 (P = 0.007) were significantly higher in the aqueous humour samples from POAG. The levels of BDNF, sICAM-1, MPO and PAI-1 did not differ among the groups. Mean deviation (MD) values measured by the Humphrey Visual Field Analyzer were significantly associated with levels of cathepsin D (P < 0.001; rho= - 0.668), sICAM-1 (P = 0.003; rho= - 0.579), sVCAM-1(P < 0.001; rho= - 0.695), and PAI-1 (P = 0.007; rho= - 0.533). The cytokines showed a positive correlation among each other (P < 0.0083). CONCLUSION: These data suggest that POAG patients had elevated levels of multiple biomarkers of neurodegeneration in the aqueous humour, and these elevated biomarkers may be related to trabecular meshwork injury. TRIAL REGISTRATION: This study was registered in the Chinese Clinical Trial Registry ( ChiCTR-OOC-16008516 ) on May 22, 2016. PMID- 29183304 TI - Dental caries experience and determinants in young adults of the Northern State Medical University, Arkhangelsk, North-West Russia: a cross-sectional study. AB - BACKGROUND: Little information exists about the experience of and risk factors for dental caries in young adults in Russia. We investigated dental caries experience and determinants in medical and dental students in North-West Russia. METHODS: This cross-sectional study included 442 medical and 309 dental undergraduate students of Russian nationality aged 18-25 years from the Northern State Medical University, Arkhangelsk, Russia. Information on socio-demographic factors and oral health behaviour (regularity of dental visits, frequency of tooth-brushing, using toothpaste with fluoride, and skipping tooth-brushing) was obtained from a structured, self-administered questionnaire. Dental caries experience was based on the decayed (D) missing (M) filled (F) teeth (T) index and the Significant Caries (SiC) index, which were assessed through dental examination. Students with a DMFT index >=9 were placed in the SiC group. Negative binomial hurdle and multivariable binary logistic regressions were used for statistical analyses. RESULTS: The prevalence of dental caries (DMFT >0) was 96.0%, overall mean DMFT index was 7.58 (DT: 0.61, MT: 0.12, and FT: 6.84), and the corresponding SiC index was 12.50. Age 21-25 years (incidence rate ratio [IRR] = 1.09, 95% confidence interval [CI]: 1.01-1.18), being a female (IRR = 1.10, 95% CI: 1.01-1.20), high subjective socioeconomic status (SES) [IRR = 1.11, 95% CI: 1.02-1.21], and skipping tooth-brushing (IRR = 1.09, 95% CI: 1.00-1.19) were associated with a higher DMFT index. DMFT index also increased among students who reported regular dental visits (IRR = 1.22, 95% CI: 1.10-1.36), but their odds of being in the dental caries-free group decreased (odds ratio [OR] = 0.38, 95% CI: 0.18-0.82). Significant predictors of being categorised to the SiC group were older age (OR = 1.41, 95% CI: 1.03-1.92), high subjective SES (OR = 1.57, 95% CI: 1.13-2.19), and regular dental visits (OR = 2.34, 95% CI: 1.56 3.51). CONCLUSIONS: A high prevalence of dental caries and high DMFT index, with a dominance of FT, were observed in our Russian medical and dental students. Age, sex, subjective SES, regular dental visits, and skipping tooth-brushing were determinants of dental caries experience. PMID- 29183305 TI - Hemodynamic benefits of celiac artery release for ruptured right gastric artery aneurysm associated with median arcuate ligament syndrome: a case report. AB - BACKGROUND: It has been reported that median arcuate ligament syndrome is closely associated with gastric or pancreaticoduodenal artery aneurysms. Hemodynamic state plays an important role in the formation of the aneurysms. These aneurysms are treated with open resection or endovascular exclusion. However, whether revascularization of the celiac artery can prevent the aneurysm formation is unknown. This report indicated a possibility that prophylactic revascularization for celiac artery stenosis resulted in decreased shear stress on the collaterals, which may otherwise be susceptible to new aneurysms. CASE PRESENTATION: This report describes a 51-year-old man who presented with epigastric pain at our hospital. According to contrast enhanced computed tomography (CT), he was diagnosed with a ruptured right gastric artery aneurysm and celiac artery stenosis caused by the median arcuate ligament (MAL). He had a vascular anomaly of the common hepatic artery arising from the superior mesenteric artery (SMA). His vital signs were stable. We informed him of the situation and he chose open surgery rather than endovascular treatment. Following, we resected the aneurysm and transected the MAL. Intraoperative angiography after transection of the MAL showed the antegrade blood flow to the splenic artery instead of the retrograde flow via the prominent collaterals. Follow-up CT confirmed narrowed collateral vessels between the SMA and the celiac artery without de-novo aneurysms. CONCLUSION: While the necessity of celiac artery release could be questioned, the present case supports the hemodynamic benefits of MAL transection in terms of de novo aneurysm prevention. PMID- 29183306 TI - ACDF vs TDR for patients with cervical spondylosis - an 8 year follow up study. AB - BACKGROUND: ACDF has been considered as the gold standard in the treatment of single level cervical disk protrusion. However, it may cause adjacent level degeneration due to regional biomechanical changes. TDR has been applied with satisfactory results for over a decade, but there is no consensus if TDR is safer and more efficient than ACDF. The current study was carried out to compare the efficiency and safety of TDR and ACDF in the treatment of patients with single level cervical disk protrusion. METHODS: One hundred forty-five consecutive patients who underwent either TDR or ACDF in our center were included in the current study. Time of surgery, intraoperative blood loss, VAS arm and neck pain scores, ROM, ODI, SF36 and Patient satisfaction were compared before the surgery, after the surgery, and during follow up 1, 3, 5, 8 years after the surgery. RESULTS: The time of surgery was 64.6 +/- 20.7 min in the ACDF group and 69.4 +/- 19.3 min in the TDR group; intraoperative hemorrhage was 67.2 +/- 14.3 ml in ACDF group and 70.7 +/- 18.6 ml in TDR group. There were no significant differences between two groups concerning time of surgery and intraoperative blood loss. No differences were found concerning patient satisfaction between the two groups during the follow up (P > 0.05). Significant differences were found between the groups concerning VAS arm and neck pain scores, ROM, ODI and SF36 after the surgery and during the 8 year follow up. CONCLUSION: TDR may be a more effective approach than ACDF for treating patients with single level cervical disk protrusion. PMID- 29183307 TI - The immediate effect of muscle release intervention on muscle activity and shoulder kinematics in patients with frozen shoulder: a cross-sectional, exploratory study. AB - BACKGROUND: Contractile tissue plays an important role in mobility deficits in frozen shoulder (FS). However, no study has assessed the effect of the muscle release technique on the muscle activation and kinematics in individuals with FS. The purposes of this study were to assess the differences in shoulder muscle activity and kinematics between the FS and asymptomatic groups; and to determine the immediate effects of muscle release intervention in the FS group. METHODS: Twenty patients with FS and 20 asymptomatic controls were recruited. The outcome measures included muscle activity of the upper and lower trapezius (UT and LT), infraspinatus (ISp), pectoralis major (PM), and teres major (TM), shoulder kinematics (humeral elevation, scapular posterior tilt (PT) and upward rotation (UR), shoulder mobility, and pain. Participants in the FS group received one session of heat and manual muscle release. Measurements were obtained at baseline, and immediately after intervention. Multivariate analysis of variance was used for data analysis. The level of significance was set at alpha=0.05. RESULTS: Compared to the controls, the FS group revealed significantly decreased LT (difference =55.89%, P=0.001) and ISp muscle activity (difference =26.32%, P =0.043) during the scaption task, and increased PM activity (difference =6.31%, P =0.014) during the thumb to waist task. The FS group showed decreased humeral elevation, scapular PT, and UR (difference = 35.36 degrees , 10.18 degrees , 6.73 degrees respectively, P <0.05). Muscle release intervention immediately decreased pain (VAS drop 1.7, P <0.001); improved muscle activity during scaption (UT: 12.68% increase, LT: 35.46% increase, P <0.05) and hand to neck (UT: 12.14% increase, LT: 34.04% increase, P <0.05) task; and increased peak humeral elevation and scapular PT during scaption (95.18 degrees +/-15.83 degrees to 98.24 degrees +/-15.57 degrees , P=0.034; 11.06 degrees +/-3.94 degrees to 14.36 degrees +/-4.65 degrees , P=0.002), and increased scapular PT during the hand to neck (9.47 degrees +/-3.86 degrees to 12.80 degrees +/-8.33 degrees , P=0.025) task. No statistical significance was found for other group comparisons or intervention effect. CONCLUSION: Patients with FS presented with altered shoulder muscle activity and kinematics, and one-session of heat and manual muscle release showed beneficial effects on shoulder muscle performance, kinematics, mobility, and pain. TRIAL REGISTRATION: Retrospectively registered on Jan 18, 2016 (ACTRN 12616000031460 ). PMID- 29183308 TI - Frequency of visits and examinations in the Public Dental Service in Finland - a retrospective analysis, 2001-2013. AB - BACKGROUND: This study aimed to investigate longitudinally examination and visiting patterns in the Finnish Public Dental Service (PDS) and to relate these to patients' treatment needs and international recommendations on examination intervals. METHODS: Data on patients and their dental visits in the period 2001 2013 were collected from five municipal PDS-units serving a total population of 320,000 inhabitants and using the same database system. Ethical approval was given by the National Institute for Health and Welfare (THL) and permissions to use local data by the directors of health services in each unit. For each year, the numbers of visitors, those examined and those in need of basic periodontal or caries treatment (CPI >2 and D + d > 0) were calculated separately for young people (< 18 years), the working-aged (18-64 years) and the elderly (65+ years). Each individual's examination and visiting intervals were counted. Multilevel modelling was used to study probabilities of being examined or in need of treatment and differences in examination and visiting intervals between groups and over time. RESULTS: From 2001 to 2013, the number of visitors increased by 39.3% and the working-aged became the biggest patient group rather than the young. Compared with adults, the young were five times more likely to be examined (OR = 4.97) and three times less likely to require treatment (OR = 0.31). On average, 37% of the young, 73% of the working-aged and 63% of the elderly needed basic treatment. Multi-level analysis showed that the young had the shortest examination intervals and the working aged the longest (0.50 years longer). Most examination intervals of the young and the elderly were 1 year (65.2 - 77.0%), but only half (49.5%) of the working-aged were re-examined within 1 year. Over time, the examination intervals increased slightly in all groups. Most visiting intervals remained at 1 year. CONCLUSION: Young patients had mostly annual or biannual examinations, in line with recommendations. The examination intervals of working aged adults were considerably longer, and more of them needed treatment. The share of elderly among visitors remained low. The PDS seems to have access barriers for adults. PMID- 29183309 TI - Assessment of the effects of skin microneedling as adjuvant therapy for facial melasma: a pilot study. AB - BACKGROUND: Melasma is a common chronic and relapsing acquired dyschromia. Skin microneedling was reported resulting sustained long-term improvement of recalcitrant melasma, however, the exact mechanism that promotes this skin lightening is not known. This study aimed to investigate clinical and histologic alterations promoted by skin microneedling in facial melasma. METHODS: Open pilot trial including six women with facial refractory melasma submitted to two sessions of microneedling (1.5 mm) each 30 days followed by daily triple combination and broad-spectrum sunscreen. Comparison of pretreatment (T0) and 15 days after last microneedling procedure (T45) was made by standardized pictures, skin colorimetry, MASI, MELASQoL and histological parameters (haematoxylin-eosin, picrosirius-red, periodic acid Schiff and Fontana-Masson staining). RESULTS: The age of the subjects varied from 34 to 46 years-old, the phototypes were III and IV (Fitzpatrick), and age of melasma onset was 20 to 38 years. Improvement of melasma was perceived in all subjects. There was a significant reduction of MASI score (-70%), MELASQoL (-55%) and increase in L* (+13%) colorimetric value (p < 0.03). All cases evidenced epithelium thickening, decrease in melanin pigmentation and densification of upper dermis collagen (p = 0.03). Patients were followed by 6 months under broad-spectrum sunscreen and triple combination without relapse. CONCLUSION: In addition to classic treatment (broad-spectrum sunscreen and triple combination), skin microneedling promoted clinical and histological improvement of refractory facial melasma. PMID- 29183310 TI - Reasons for encounters and psychiatric comorbidity in an urban Bavarian primary care out-of-hour service - results of a cross sectional study. AB - BACKGROUND: International studies have shown a contribution of psychiatric comorbidity to high utilization rates in out-of-hour primary care (OOHC). Up to now, the impact of psychiatric comorbidity in German OOHC remains unclear. Therefore, we aimed to investigate reasons for encounter (RFE), possible psychiatric comorbidity, utilization rates, and a possible association between utilization rate and psychiatric comorbidity among patients of an urban OOHC unit. METHODS: In a cross-sectional, prospective, naturalistic study five hundred self-referred patients completed a self-designed questionnaire addressing RFE, past office visits and personal information. Additionally, we employed three validated questionnaires (PHQ-9, PHQ-15 and GAD-7) to screen for mental disorders. We collected information about past visits through computerized patients' charts. Diagnoses were classified according to the International Classification of Primary Care-2. RESULTS: The most frequent RFE were musculoskeletal complaints (36%), followed by respiratory diseases (13%), gastrointestinal problems (10%), skin conditions (8%) and urologic ailments (6%). Of the included patients 58% were working fulltime and 61% had greater than or equal to 10 years of education. The mean age was 37.3 in females and 40.5 years in males. Prevalence of psychiatric comorbidity was 27%. Only 3% visited the office more than twice over a 12 months period. We could not find an association between high utilization and psychiatric comorbidity. CONCLUSION: In this study, musculoskeletal complaints were the most frequent RFE. Patients were predominantly young, employed and educated. The prevalence of psychiatric comorbidity was similar to the prevalence in common general practitioner offices and showed no significant relation to frequent attendance. This information might help to prepare physicians better for patient care in OOHC. PMID- 29183311 TI - Successful access to the ampulla for endoscopic retrograde cholangiopancreatography in patients with situs inversus totalis: a case report. AB - BACKGROUND: Although various endoscopic techniques in situs inversus have been reported, endoscopic retrograde cholangiopancreatography (ERCP) in patients with situs inversus is always challenging even for an experienced endoscopist. We performed ERCP using two different techniques, and compare the merits of each technique. CASE PRESENTATION: A 74-year-old woman presented with epigastric pain and jaundice for 3 days. Computed tomography revealed diffuse dilatation of the biliary tree, with multiple intrahepatic duct and common bile duct (CBD) stones, in addition to situs inversus totalis. ERCP was performed twice for CBD stone to remove the CBD stones using two techniques. For the first technique used, the patient was placed in a prone position with the endoscopist on the right side of the table. First, the endoscope was rotated 180 degrees counterclockwise in the stomach, and was then shortened by turning 180 degrees the counterclockwise again in the duodenum. For the second technique, we assessed the second portion of the duodenum by following the lesser curvature, while slowly turning the endoscope clockwise. CONCLUSION: We present an unusual case of biliary stones in a patient with situs inversus who was treated using modified ERCP techniques. PMID- 29183312 TI - Integrated community case management in a peri-urban setting: a qualitative evaluation in Wakiso District, Uganda. AB - BACKGROUND: Integrated community case management (iCCM) strategies aim to reach poor communities by providing timely access to treatment for malaria, pneumonia and diarrhoea for children under 5 years of age. Community health workers, known as Village Health Teams (VHTs) in Uganda, have been shown to be effective in hard to-reach, underserved areas, but there is little evidence to support iCCM as an appropriate strategy in non-rural contexts. This study aimed to inform future iCCM implementation by exploring caregiver and VHT member perceptions of the value and effectiveness of iCCM in peri-urban settings in Uganda. METHODS: A qualitative evaluation was conducted in seven villages in Wakiso district, a rapidly urbanising area in central Uganda. Villages were purposively selected, spanning a range of peri-urban settlements experiencing rapid population change. In each village, rapid appraisal activities were undertaken separately with purposively selected caregivers (n = 85) and all iCCM-trained VHT members (n = 14), providing platforms for group discussions. Fifteen key informant interviews were also conducted with community leaders and VHT members. Thematic analysis was based on the 'Health Access Livelihoods Framework'. RESULTS: iCCM was perceived to facilitate timely treatment access and improve child health in peri-urban settings, often supplanting private clinics and traditional healers as first point of care. Relative to other health service providers, caregivers valued VHTs' free, proximal services, caring attitudes, perceived treatment quality, perceived competency and protocol use, and follow-up and referral services. VHT effectiveness was perceived to be restricted by inadequate diagnostics, limited newborn care, drug stockouts and VHT member absence - factors which drove utilisation of alternative providers. Low community engagement in VHT selection, lack of referral transport and poor availability of referral services also diminished perceived effectiveness. The iCCM strategy was widely perceived to result in economic savings and other livelihood benefits. CONCLUSIONS: In peri urban areas, iCCM was perceived as an effective, well-utilised strategy, reflecting both VHT attributes and gaps in existing health services. Depending on health system resources and organisation, iCCM may be a useful transitional service delivery approach. Implementation in peri-urban areas should consider tailored community engagement strategies, adapted selection criteria, and assessment of population density to ensure sufficient coverage. PMID- 29183313 TI - Location of unaccessible implant surface areas during debridement in simulated peri-implantitis therapy. AB - BACKGROUND: An in vitro model for peri-implantitis treatment was used to identify areas that are clinically difficult to clean by analyzing the pattern of residual stain after debridement with commonly employed instruments. METHODS: Original data from two previous publications, which simulated surgical (SA) and non surgical (NSA) implant debridement on two different implant systems respectively, were reanalyzed regarding the localization pattern of residual stains after instrumentation. Two blinded examiners evaluated standardized photographs of 360 initially ink-stained dental implants, which were cleaned at variable defect angulations (30, 60, or 90 degrees ), using different instrument types (Gracey curette, ultrasonic scaler or air powder abrasive device) and treatment approaches (SA or NSA). Predefined implant surface areas were graded for residual stain using scores ranging from one (stain-covered) to six (clean). Score differences between respective implant areas were tested for significance by pairwise comparisons using Wilcoxon-rank-sum-tests with a significance level alpha = 5%. RESULTS: Best scores were found at the machined surface areas (SA: 5.58 +/- 0.43, NSA: 4.76 +/- 1.09), followed by the tips of the threads (SA: 4.29 +/- 0.44, NSA: 4.43 +/- 0.61), and areas between threads (SA: 3.79 +/- 0.89, NSA: 2.42 +/- 1.11). Apically facing threads were most difficult to clean (SA: 1.70 +/ 0.92, NSA: 2.42 +/- 1.11). Here, air powder abrasives provided the best results. CONCLUSION: Machined surfaces at the implant shoulder were well accessible and showed least amounts of residual stain. Apically facing thread surfaces constituted the area with most residual stain regardless of treatment approach. PMID- 29183314 TI - Does clinical supervision of healthcare professionals improve effectiveness of care and patient experience? A systematic review. AB - BACKGROUND: To ensure quality of care delivery clinical supervision has been implemented in health services. While clinical supervision of health professionals has been shown to improve patient safety, its effect on other dimensions of quality of care is unknown. The purpose of this systematic review is to determine whether clinical supervision of health professionals improves effectiveness of care and patient experience. METHODS: Databases MEDLINE, PsychINFO, CINAHL, EMBASE and AMED were searched from earliest date available. Additional studies were identified by searching of reference lists and citation tracking. Two reviewers independently applied inclusion and exclusion criteria. The quality of each study was rated using the Medical Education Research Study Quality Instrument. Data were extracted on effectiveness of care (process of care and patient health outcomes) and patient experience. RESULTS: Seventeen studies across multiple health professions (medical (n = 4), nursing (n = 7), allied health (n = 2) and combination of nursing, medical and/or allied health (n = 4)) met the inclusion criteria. The clinical heterogeneity of the included studies precluded meta-analysis. Twelve of 14 studies investigating 38,483 episodes of care found that clinical supervision improved the process of care. This effect was most predominant in cardiopulmonary resuscitation and African health settings. Three of six studies investigating 1756 patients found that clinical supervision improved patient health outcomes, namely neurological recovery post cardiopulmonary resuscitation (n = 1) and psychological symptom severity (n = 2). None of three studies investigating 1856 patients found that clinical supervision had an effect on patient experience. CONCLUSIONS: Clinical supervision of health professionals is associated with effectiveness of care. The review found significant improvement in the process of care that may improve compliance with processes that are associated with enhanced patient health outcomes. While few studies found a direct effect on patient health outcomes, when provided to mental health professionals clinical supervision may be associated with a reduction in psychological symptoms of patients diagnosed with a mental illness. There was no association found between clinical supervision and the patient experience. REVIEW REGISTRATION: CRD42015029643 . PMID- 29183315 TI - Prevalence of poor mental health among medical students in Nepal: a cross sectional study. AB - BACKGROUND: Poor mental health among medical students is widely acknowledged. Studies on mental health among medical students of Nepal are lacking. Therefore, we conducted a study to determine the prevalence of mental disorders. METHODS: A cross-sectional study was conducted among medical students at KIST Medical College and Teaching Hospital, Nepal from December 2016 to February 2017. Our survey instrument consisted of the Patient Health Questionnaire (PHQ) and questions about socio-demographic factors, smoking, marijuana use, suicidal ideation and thoughts of dropping out of medical school. RESULTS: The prevalence rates were 29.2% (95% CI, 24.4% - 34.3%) depression, 22.4% (95% CI, 18.0% - 26.9%) medium to highly severe somatic symptoms, 4.1% (95% CI, 2.0% - 6.2%) panic syndrome, 5.8% (95% CI, 3.4% - 8.3%) other anxiety syndrome, 5% (95% CI, 2.7% - 7.3%) binge eating disorder and 1.2% (95% CI, 0.0% - 2.3%) bulimia nervosa. Sixteen students [4.7% (95% CI, 2.4% - 6.9%)] seriously considered committing suicide while in medical school. Thirty-four students [9.9% (95% CI, 6.8% - 13.1%)] considered dropping out of medical school within the past month. About 15% (95% CI, 11.1% - 18.6%) of the students reported use of marijuana during medical school. CONCLUSIONS: We found high prevalence of poor mental health among medical students of Nepal. Future studies are required to identify the factors associated with poor mental health. PMID- 29183316 TI - RNA sequencing reveals candidate genes and polymorphisms related to sperm DNA integrity in testis tissue from boars. AB - BACKGROUND: Sperm DNA is protected against fragmentation by a high degree of chromatin packaging. It has been demonstrated that proper chromatin packaging is important for boar fertility outcome. However, little is known about the molecular mechanisms underlying differences in sperm DNA fragmentation. Knowledge of sequence variation influencing this sperm parameter could be beneficial in selecting the best artificial insemination (AI) boars for commercial production. The aim of this study was to identify genes differentially expressed in testis tissue of Norwegian Landrace and Duroc boars, with high and low sperm DNA fragmentation index (DFI), using transcriptome sequencing. RESULTS: Altogether, 308 and 374 genes were found to display significant differences in expression level between high and low DFI in Landrace and Duroc boars, respectively. Of these genes, 71 were differentially expressed in both breeds. Gene ontology analysis revealed that significant terms in common for the two breeds included extracellular matrix, extracellular region and calcium ion binding. Moreover, different metabolic processes were enriched in Landrace and Duroc, whereas immune response terms were common in Landrace only. Variant detection identified putative polymorphisms in some of the differentially expressed genes. Validation showed that predicted high impact variants in RAMP2, GIMAP6 and three uncharacterized genes are particularly interesting for sperm DNA fragmentation in boars. CONCLUSIONS: We identified differentially expressed genes between groups of boars with high and low sperm DFI, and functional annotation of these genes point towards important biochemical pathways. Moreover, variant detection identified putative polymorphisms in the differentially expressed genes. Our results provide valuable insights into the molecular network underlying DFI in pigs. PMID- 29183317 TI - Smad4 SUMOylation is essential for memory formation through upregulation of the skeletal myopathy gene TPM2. AB - BACKGROUND: Smad4 is a critical effector of TGF-beta signaling that regulates a variety of cellular functions. However, its role in the brain has rarely been studied. Here, we examined the molecular mechanisms underlying the post translational regulation of Smad4 function by SUMOylation, and its role in spatial memory formation. RESULTS: In the hippocampus, Smad4 is SUMOylated by the E3 ligase PIAS1 at Lys-113 and Lys-159. Both spatial training and NMDA injection enhanced Smad4 SUMOylation. Inhibition of Smad4 SUMOylation impaired spatial learning and memory in rats by downregulating TPM2, a gene associated with skeletal myopathies. Similarly, knockdown of TPM2 expression impaired spatial learning and memory, while TPM2 mRNA and protein expression increased after spatial training. Among the TPM2 mutations associated with skeletal myopathies, the TPM2E122K mutation was found to reduce TPM2 expression and impair spatial learning and memory in rats. CONCLUSIONS: We have identified a novel role of Smad4 SUMOylation and TPM2 in learning and memory formation. These results suggest that patients with skeletal myopathies who carry the TPM2E122K mutation may also have deficits in learning and memory functions. PMID- 29183318 TI - The development, implementation and evaluation of clinical pathways for chronic obstructive pulmonary disease (COPD) in Saskatchewan: protocol for an interrupted times series evaluation. AB - BACKGROUND: Chronic obstructive pulmonary disease (COPD) has substantial economic and human costs; it is expected to be the third leading cause of death worldwide by 2030. To minimize these costs high quality guidelines have been developed. However, guidelines alone rarely result in meaningful change. One method of integrating guidelines into practice is the use of clinical pathways (CPWs). CPWs bring available evidence to a range of healthcare professionals by detailing the essential steps in care and adapting guidelines to the local context. METHODS/DESIGN: We are working with local stakeholders to develop CPWs for COPD with the aims of improving care while reducing utilization. The CPWs will employ several steps including: standardizing diagnostic training, unifying components of chronic disease care, coordinating education and reconditioning programs, and ensuring care uses best practices. Further, we have worked to identify evidence informed implementation strategies which will be tailored to the local context. We will conduct a three-year research project using an interrupted time series (ITS) design in the form of a multiple baseline approach with control groups. The CPW will be implemented in two health regions (experimental groups) and two health regions will act as controls (control groups). The experimental and control groups will each contain an urban and rural health region. Primary outcomes for the study will be quality of care operationalized using hospital readmission rates and emergency department (ED) presentation rates. Secondary outcomes will be healthcare utilization and guideline adherence, operationalized using hospital admission rates, hospital length of stay and general practitioner (GP) visits. Results will be analyzed using segmented regression analysis. DISCUSSION: Funding has been procured from multiple stakeholders. The project has been deemed exempt from ethics review as it is a quality improvement project. Intervention implementation is expected to begin in summer of 2017. This project is expected to improve quality of care and reduce healthcare utilization. In addition it will provide evidence on the effects of CPWs in both urban and rural settings. If the CPWs are found effective we will work with all stakeholders to implement similar CPWs in surrounding health regions. TRIAL REGISTRATION: Clinicaltrials.gov ( NCT03075709 ). Registered 8 March 2017. PMID- 29183319 TI - PPARalpha is essential for retinal lipid metabolism and neuronal survival. AB - BACKGROUND: Peroxisome proliferator activated receptor-alpha (PPARalpha) is a ubiquitously expressed nuclear receptor. The role of endogenous PPARalpha in retinal neuronal homeostasis is unknown. Retinal photoreceptors are the highest energy-consuming cells in the body, requiring abundant energy substrates. PPARalpha is a known regulator of lipid metabolism, and we hypothesized that it may regulate lipid use for oxidative phosphorylation in energetically demanding retinal neurons. RESULTS: We found that endogenous PPARalpha is essential for the maintenance and survival of retinal neurons, with Pparalpha -/- mice developing retinal degeneration first detected at 8 weeks of age. Using extracellular flux analysis, we identified that PPARalpha mediates retinal utilization of lipids as an energy substrate, and that ablation of PPARalpha ultimately results in retinal bioenergetic deficiency and neurodegeneration. This may be due to PPARalpha regulation of lipid transporters, which facilitate the internalization of fatty acids into cell membranes and mitochondria for oxidation and ATP production. CONCLUSION: We identify an endogenous role for PPARalpha in retinal neuronal survival and lipid metabolism, and furthermore underscore the importance of fatty acid oxidation in photoreceptor survival. We also suggest PPARalpha as a putative therapeutic target for age-related macular degeneration, which may be due in part to decreased mitochondrial efficiency and subsequent energetic deficits. PMID- 29183320 TI - Fungal 7-epi-10-deacetyltaxol produced by an endophytic Pestalotiopsis microspora induces apoptosis in human hepatocellular carcinoma cell line (HepG2). AB - BACKGROUND: Paclitaxel (taxol) is a potent anticancer drug that is used in the treatment of a wide variety of cancerous. In the present study, we identified a taxol derivative named 7-epi-10-deacetyltaxol (EDT) from the culture of an endophytic fungus Pestalotiopsis microspora isolated from the bark of Taxodium mucronatum. This study was carried out to investigate the effects of fungal EDT on cell proliferation, the induction of apoptosis and the molecular mechanisms of apoptosis in human hepatoma HepG2 cells in vitro. METHODS: The endophytic fungus was identified by traditional and molecular taxonomical characterization and the fungal EDT was purified using column chromatography and confirmed by various spectroscopic and chromatographic comparisons with authentic paclitaxel. We studied the in vitro effects of EDT on HepG2 cells for parameters such as cell cycle distribution, DNA fragmentation, reactive oxygen species (ROS) generation and nuclear morphology. Further, western blot analysis was used to evaluate Bcl-2 associated X protein (Bax), B-cell lymphoma 2 (Bcl-2), p38-mitogen activated protein kinase (MAPK) and poly [ADP-ribose] polymerase (PARP) expression. RESULTS: We demonstrate that the fungal EDT exhibited significant in vitro cytotoxicity in HepG2 cells. We investigated cytotoxicity mechanism of EDT in HepG2 cells. The results showed nuclear condensation and DNA fragmentation were observed in cells treated with fungal EDT. Besides, the fungal EDT arrested HepG2 cells at G2/M phase of cell cycle. Furthermore, fungal EDT induced apoptosis in HepG2 cells in a dose-dependent manner associated with ROS generation and increased Bax/Bcl-2 ratio, p38 MAPKs and PARP cleavage. CONCLUSIONS: Our data show that EDT induced apoptotic cell death in HepG2 cells occurs through intrinsic pathway by generation of ROS mediated and activation of MAPK pathway. This is the first report for 7-epi-10-deacetyltaxol (EDT) isolated from a microbial source. PMID- 29183321 TI - Effects of controlled hypoxemia or hypovolemia on global and intestinal oxygenation and perfusion in isoflurane anesthetized horses receiving an alpha-2 agonist infusion. AB - BACKGROUND: Aim of this prospective experimental study was to assess effects of systemic hypoxemia and hypovolemia on global and gastrointestinal oxygenation and perfusion in anesthetized horses. Therefore, we anesthetized twelve systemically healthy warmblood horses using either xylazine or dexmedetomidine for premedication and midazolam and ketamine for induction. Anesthesia was maintained using isoflurane in oxygen with either xylazine or dexmedetomidine and horses were ventilated to normocapnia. During part A arterial oxygen saturation (SaO2) was reduced by reducing inspiratory oxygen fraction in steps of 5%. In part B hypovolemia was induced by controlled arterial exsanguination via roller pump (rate: 38 ml/kg/h). Mean arterial blood pressure (MAP), heart rate, pulmonary artery pressure, arterial and central venous blood gases and cardiac output were measured, cardiac index (CI) was calculated. Intestinal microperfusion and oxygenation were measured using laser Doppler flowmetry and white-light spectrophotometry. Surface probes were placed via median laparotomy on the stomach, jejunum and colon. RESULTS: Part A: Reduction in arterial oxygenation resulted in a sigmoid decrease in central venous oxygen partial pressure. At SaO2 < 80% no further decrease in central venous oxygen partial pressure occurred. Intestinal oxygenation remained unchanged until SaO2 of 80% and then decreased. Heart rate and pulmonary artery pressure increased significantly during hypoxemia. Part B: Progressive reduction in circulating blood volume resulted in a linear decrease in MAP and CI. Intestinal perfusion was preserved until blood loss resulted in MAP and CI lower 51 +/- 5 mmHg and 40 +/- 3 mL/kg/min, respectively, and then decreased rapidly. CONCLUSIONS: Under isoflurane, intestinal tissue oxygenation remained at baseline when arterial oxygenation exceeded 80% and intestinal perfusion remained at baseline when MAP exceeded 51 mmHg and CI exceeded 40 mL/kg/min in this group of horses. TRIAL REGISTRY NUMBER: 33.14-42,502-04-14/1547. PMID- 29183322 TI - Extracts of Zuo Jin Wan, a traditional Chinese medicine, phenocopies 5-HTR1D antagonist in attenuating Wnt/beta-catenin signaling in colorectal cancer cells. AB - BACKGROUND: In vitro and in vivo studies have shown that Zuo Jin Wan (ZJW), a herbal formula of traditional Chinese medicine (TCM), possessed anticancer properties. However, the underlying mechanism for the action of ZJW remains unclear. Various subtypes of 5-Hydroxytryptamine receptor (5-HTR) have been shown to play a role in carcinogenesis and cancer metastasis. 5-HTR1D, among the subtypes, is highly expressed in colorectal cancer (CRC) cell lines and tissues. The present study aimed at investigating effect of ZJW extracts on the biological function of CRC cells, the expression of 5-HTR1D, and molecules of Wnt/beta catenin signaling pathway. METHODS: In this study, the effect of ZJW extracts on 5-HTR1D expression and Wnt/beta-catenin signaling pathway were investigated and contrasted with GR127935 (GR), a known 5-HTR1D antagonist, using the CRC cell line SW403. The cells were respectively treated with GR127935 and different doses of ZJW extracts. Proliferation, apoptosis, migration, and invasion of SW403 cells were compared between ZJW and GR127935 treatments. The expression of 5-HTR1D and signaling molecules involved in the canonic Wnt/beta-catenin pathway were determined by Western blot analysis. RESULTS: After ZJW extracts treatment and GR127935 treatment, G1 arrest in cell cycle of SW403 was increased. Cell apoptosis was pronounced, and cell migration and invasion were suppressed. SW403 cells showed a dose-dependently decreased expression of 5-HTR1D, meanwhile, beta catenin level was significantly decreased in nucleus of cells cultured with GR127935. Treatment of ZJW extracts dose-dependently resulted in decreased 5 HTR1D and a concomitant reduction in the Wnt/beta-catenin signal transduction, an effect indistinguishable from GR127935 treatment. CONCLUSION: The anticancer activity of ZJW extracts may be partially achieved through attenuation of the 5 HTR1D-Wnt/beta-catenin signaling pathway. PMID- 29183323 TI - Cervical metastasis of gingival carcinoma misdiagnosed as branchiogenic carcinoma, a rare entity - report of a case and review of literature. AB - BACKGROUND: A cervical cystic mass is associated with a number of pathologies that present with similar symptoms. These conditions are difficult to differentiate using fine-needle aspiration (FNA), ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI). Another dilemma in the differential diagnosis of cervical cystic masses is due to the controversies associated with the existence of branchiogenic carcinoma (BC). BC is an extremely rare disease that must be differentiated from other conditions presenting with cervical cystic masses, especially cystic metastasis from occult primary lesions. CASE PRESENTATION: We present a case report of a right cervical cystic metastasis from a significantly small squamous cell carcinoma primary gingival lesion misdiagnosed as BC by histopathology. A 62-year-old female presented with a painless progressively enlarging cervical mass at the anterior edge of the sternocleidomastoid muscle in the right submandibular region. Preoperative MRI and US revealed a well-defined cystic round mass. Postoperative histological examination indicated BC. Positron emission tomography/computed tomography (PET/CT) revealed high 18F-FDG (18F 2-fluoro-2-deoxy-D-glucose) uptake in surgical regions with a SUV (standard uptake value) max 4.0 and ipsilateral nasopharynx with a SUVmax 4.4, without any distant metastasis. Pathologic results revealed nasopharyngeal lymphadenosis. Considering the low incidence of BC and the limitation of diagnosis in one institution, the patient was referred to another hospital. Physical examination detected a significantly small neoplasm (~3 mm diameter) in the right lower gingiva. Histopathological examination of the neoplasm revealed a well-differentiated squamous cell carcinoma. Surgery, including a partial mandibulectomy and modified neck dissection (neck level I-V and submental lymph nodes) were undertaken. Postoperative histopathological results revealed a well-differentiated squamous cell carcinoma of right lower gingiva and two metastatic lymph nodes in the 18 lymph nodes of level II. A month later, recurrence occurred in the right cervical level II. The patient was placed on postoperative concurrent chemo-radiotherapy and supportive care. The patient suffered from cachexia and survived for only six months after surgery. CONCLUSIONS: In cases of cervical cystic masses that appear after the age of 40, clinicians should bear in mind that occult primary lesions should be excluded and examination of the gingiva should be undertaken. PET/CT has a limited role in identifying small occult primary lesions and a comprehensive physical examination must be carefully performed. PMID- 29183324 TI - Novel essential amino acid supplements enriched with L-leucine facilitate increased protein and energy intakes in older women: a randomised controlled trial. AB - BACKGROUND: Inadequate protein intake (PI), containing a sub-optimal source of essential amino acids (EAAs), and reduced appetite are contributing factors to age-related sarcopenia. The satiating effects of dietary protein per se may negatively affect energy intake (EI), thus there is a need to explore alternative strategies to facilitate PI without compromising appetite and subsequent EI. METHODS: Older women completed two experiments (EXP1 and EXP2) where they consumed either a Bar (565 kJ), a Gel (477 kJ), both rich in EAAs (7.5 g, 40% L leucine), or nothing (Control). In EXP1, participants (n = 10, 68 +/- 5 years, mean +/- SD) consumed Bar, Gel or Control with appetite sensations and appetite related hormonal responses monitored for one hour, followed by consumption of an ad libitum breakfast (ALB). In EXP2, participants (n = 11, 69 +/- 5 years) ingested Bar, Gel or Control alongside an ALB. RESULTS: In EXP1, EI at ALB was not different (P = 0.674) between conditions (1179 +/- 566, 1254 +/- 511, 1206 +/ 550 kJ for the Control, Bar, and Gel respectively). However, total EI was significantly higher in the Bar and Gel compared to the Control after accounting for the energy content of the supplements (P < 0.0005). Analysis revealed significantly higher appetite Area under the Curve (AUC) (P < 0.007), a tendency for higher acylated ghrelin AUC (P = 0.087), and significantly lower pancreatic polypeptide AUC (P = 0.02) in the Control compared with the Bar and Gel. In EXP2, EI at ALB was significantly higher (P = 0.028) in the Control (1282 +/- 513 kJ) compared to the Bar (1026 +/- 565 kJ) and Gel (1064 +/- 495 kJ). However, total EI was significantly higher in the Bar and Gel after accounting for the energy content of the supplements (P < 0.007). CONCLUSIONS: Supplementation with either the Bar or Gel increased total energy intake whether consumed one hour before or during breakfast. This may represent an effective nutritional means for addressing protein and total energy deficiencies in older women. TRIAL REGISTRATION: Clinical trial register: retrospectively registered, ISRCTN12977929 on. PMID- 29183325 TI - Prognostic significance of preoperative plasma D-dimer level in patients with surgically resected clinical stage I non-small cell lung cancer: a retrospective cohort study. AB - BACKGROUND: Plasma D-dimer level, a marker of hypercoagulation, has been reported to be associated with survival in several types of cancers. The present study aimed to evaluate the prognostic significance of preoperative D-dimer levels in patients with surgically resected clinical stage I non-small cell lung cancer (NSCLC). METHODS: Participants comprised 237 patients with surgically resected clinical stage I NSCLC. In addition to factors such as age, sex, and smoking status, the association between preoperative D-dimer level and survival was explored. RESULTS: Patients were divided into two groups according to D-dimer level: Group A, <= 1.0 MUg/ml (n = 170); and Group B, > 1.0 MUg/ml (n = 67). The 5-year recurrence-free survival rate was 81.6% for Group A and 66.6% for Group B (p < 0.001). The 5-year overall survival rate was 93.6% for Group A and 84.7% for Group B (p = 0.002). Multivariate survival analysis identified D-dimer level as an independent prognostic factor, along with age, maximum standardized uptake value of the primary tumor, and pathological stage. CONCLUSIONS: Preoperative D dimer level is an independent prognostic factor in patients with surgically resected clinical stage I NSCLC. PMID- 29183327 TI - Seasonal malaria chemoprevention: successes and missed opportunities. AB - Seasonal malaria chemoprevention (SMC) was recommended in 2012 for young children in the Sahel during the peak malaria transmission season. Children are given a single dose of sulfadoxine/pyrimethamine combined with a 3-day course of amodiaquine, once a month for up to 4 months. Roll-out and scale-up of SMC has been impressive, with 12 million children receiving the intervention in 2016. There is evidence of its overall benefit in routine implementation settings, and a meta-analysis of clinical trial data showed a 75% decrease in clinical malaria compared to placebo. SMC is not free of shortcomings. Its target zone includes many hard-to-reach areas, both because of poor infrastructure and because of political instability. Treatment adherence to a 3-day course of preventive treatment has not been fully documented, and could prove challenging. As SMC is scaled up, integration into a broader, community-based paradigm which includes other preventive and curative activities may prove beneficial, both for health systems and for recipients. PMID- 29183326 TI - Ochrobactrum sp. MPV1 from a dump of roasted pyrites can be exploited as bacterial catalyst for the biogenesis of selenium and tellurium nanoparticles. AB - BACKGROUND: Bacteria have developed different mechanisms for the transformation of metalloid oxyanions to non-toxic chemical forms. A number of bacterial isolates so far obtained in axenic culture has shown the ability to bioreduce selenite and tellurite to the elemental state in different conditions along with the formation of nanoparticles-both inside and outside the cells-characterized by a variety of morphological features. This reductive process can be considered of major importance for two reasons: firstly, toxic and soluble (i.e. bioavailable) compounds such as selenite and tellurite are converted to a less toxic chemical forms (i.e. zero valent state); secondly, chalcogen nanoparticles have attracted great interest due to their photoelectric and semiconducting properties. In addition, their exploitation as antimicrobial agents is currently becoming an area of intensive research in medical sciences. RESULTS: In the present study, the bacterial strain Ochrobactrum sp. MPV1, isolated from a dump of roasted arsenopyrites as residues of a formerly sulfuric acid production near Scarlino (Tuscany, Italy) was analyzed for its capability of efficaciously bioreducing the chalcogen oxyanions selenite (SeO32-) and tellurite (TeO32-) to their respective elemental forms (Se0 and Te0) in aerobic conditions, with generation of Se- and Te-nanoparticles (Se- and TeNPs). The isolate could bioconvert 2 mM SeO32- and 0.5 mM TeO32- to the corresponding Se0 and Te0 in 48 and 120 h, respectively. The intracellular accumulation of nanomaterials was demonstrated through electron microscopy. Moreover, several analyses were performed to shed light on the mechanisms involved in SeO32- and TeO32- bioreduction to their elemental states. Results obtained suggested that these oxyanions are bioconverted through two different mechanisms in Ochrobactrum sp. MPV1. Glutathione (GSH) seemed to play a key role in SeO32- bioreduction, while TeO32- bioconversion could be ascribed to the catalytic activity of intracellular NADH-dependent oxidoreductases. The organic coating surrounding biogenic Se- and TeNPs was also characterized through Fourier-transform infrared spectroscopy. This analysis revealed interesting differences among the NPs produced by Ochrobactrum sp. MPV1 and suggested a possible different role of phospholipids and proteins in both biosynthesis and stabilization of such chalcogen-NPs. CONCLUSIONS: In conclusion, Ochrobactrum sp. MPV1 has demonstrated to be an ideal candidate for the bioconversion of toxic oxyanions such as selenite and tellurite to their respective elemental forms, producing intracellular Se- and TeNPs possibly exploitable in biomedical and industrial applications. PMID- 29183328 TI - Initial psychometric validation of the questionnaire on pain caused by spasticity (QPS). AB - BACKGROUND: The Questionnaire on Pain caused by Spasticity (QPS) is a modular patient- and observer-reported outcome measure of spasticity-related pain (SRP) in children with cerebral palsy (CP). Originally developed for an English speaking population, we conducted a psychometric validation of a recently developed Chinese language version of the QPS. METHODS: This was a prospective, observational study involving 137 children/adolescents with CP and upper and/or lower limb spasticity and their parents at three sites in China. Six QPS modules were used, three each for upper and lower limb SRP assessment: a patient self report module; an interviewer-administered module used by site staff based on the cognitive, communicative, and motor abilities of a patient; and a parent/caregiver module administered for all children as an observer-reported outcome to complement the patient-reported outcome. If no assessment by the patient was possible because of age or cognitive impairments, only the parent/caregiver module was completed. Two visits with a 3-week interval provided data to evaluate and establish administrative ease of use, scoring of the QPS (factor analyses, Rasch analyses), reliability (Cronbach's alpha, intraclass correlation coefficient), validity (correlations with quality of life [PedsQLTM], motor impairment [Gross Motor Function Classification System, Gross Motor Function Measure-66, Manual Ability Classification System], and spasticity [Ashworth Scale, Modified Tardieu Scale]). RESULTS: For most children, clinic staff reported no difficulties associated with general QPS use or deciding which module to use. Children (and parents) who reported more demanding activities also reported higher levels of associated SRP (or observed SRP behavior). Activity related SRP items were combined for a total QPS score. Cronbach's alpha was low for child self-report, but was acceptable for interviewer-administered and parent reports on SRP. Test-retest reliability was high for all modules. Moderate-strong associations were frequently seen between QPS and quality of life, and were particularly strong in the child self-report group. Relatively weak associations were observed between QPS and motor impairment and spasticity. CONCLUSIONS: This first study was successful in providing initial evidence for the psychometric properties. Clinic staff were able to administer the QPS modules easily, and both children and parents were able to complete the designated QPS appropriately. PMID- 29183329 TI - Surface display of ACC deaminase on endophytic Enterobacteriaceae strains to increase saline resistance of host rice sprouts by regulating plant ethylene synthesis. AB - BACKGROUND: Most endophytic bacteria in consortia, which provide robust and broad metabolic capacity, are attractive for applications in plant metabolic engineering. The aim of this study was to investigate the effects of engineered endophytic bacterial strains on rice sprout ethylene level and growth under saline stress. A protocol was developed to synthesize engineered strains by expressing bacterial 1-aminocyclopropane-1-carboxylate (ACC) deaminase gene on cells of endophytic Enterobacter sp. E5 and Kosakonia sp. S1 (denoted as E5P and S1P, respectively). RESULTS: Results showed that ACC deaminase activities of the engineered strains E5P and S1P were significantly higher than those of the wild strains E5 and S1. About 32-41% deaminase was expressed on the surface of the engineered strains. Compared with the controls without inoculation, inoculation with the wild and engineered strains increased the deaminase activities of sprouts. Inoculation with the engineered strains increased 15-21% more deaminase activities of sprouts than with the wild strains, and reduced the ethylene concentrations of sprouts more significantly than with wild strains (P < 0.05). Inoculation with the wild and engineered strains promoted the growth of sprouts, while the promoting effects were more profound with the engineered strains than with the wild strains. The engineered strains improved saline resistance of sprouts under salt concentrations from 10 to 25 g L-1. The engineered strains promoted longer roots and shoots than the wild strains under the salt stresses, indicating that the ACC deaminases on the endophytic bacterial cells could result in plant-produced ACC degradation and inhibit plant ethylene formation. CONCLUSIONS: The protocols of expressing enzymes on endophytic bacterial cells showed greater potentials than those of plant over-expressed enzymes to increase the efficiency of plant metabolic pathways. PMID- 29183330 TI - Conversion of xylan by recyclable spores of Bacillus subtilis displaying thermophilic enzymes. AB - BACKGROUND: The Bacillus subtilis spore has long been used to display antigens and enzymes. Spore display can be accomplished by a recombinant and a non recombinant approach, with the latter proved more efficient than the recombinant one. We used the non-recombinant approach to independently adsorb two thermophilic enzymes, GH10-XA, an endo-1,4-beta-xylanase (EC 3.2.1.8) from Alicyclobacillus acidocaldarius, and GH3-XT, a beta-xylosidase (EC 3.2.1.37) from Thermotoga thermarum. These enzymes catalyze, respectively, the endohydrolysis of (1-4)-beta-D-xylosidic linkages of xylans and the hydrolysis of (1-4)-beta-D xylans to remove successive D-xylose residues from the non-reducing termini. RESULTS: We report that both purified enzymes were independently adsorbed on purified spores of B. subtilis. The adsorption was tight and both enzymes retained part of their specific activity. When spores displaying either GH10-XA or GH3-XT were mixed together, xylan was hydrolysed more efficiently than by a mixture of the two free, not spore-adsorbed, enzymes. The high total activity of the spore-bound enzymes is most likely due to a stabilization of the enzymes that, upon adsorption on the spore, remained active at the reaction conditions for longer than the free enzymes. Spore-adsorbed enzymes, collected after the two step reaction and incubated with fresh substrate, were still active and able to continue xylan degradation. The recycling of the mixed spore-bound enzymes allowed a strong increase of xylan degradation. CONCLUSION: Our results indicate that the two-step degradation of xylans can be accomplished by mixing spores displaying either one of two required enzymes. The two-step process occurs more efficiently than with the two un-adsorbed, free enzymes and adsorbed spores can be reused for at least one other reaction round. The efficiency of the process, the reusability of the adsorbed enzymes, and the well documented robustness of spores of B. subtilis indicate the spore as a suitable platform to display enzymes for single as well as multi-step reactions. PMID- 29183331 TI - Four successful pregnancies in a patient with Fontan palliation and congenital heart disease: a case report. AB - BACKGROUND: Fontan is a palliative procedure in patients with single ventricle. Single ventricle supports systemic cardiac output and pulmonary blood flow is passively directed to the right pulmonary artery. Women with Fontan palliation are reported to have increased maternal risk during pregnancy. There are few reports of successful pregnancies in such cases. However data on these pregnancies is lacking, we consider this to be the first reported from kingdom of Saudi Arabia. CASE PRESENTATION: We present a 35-year-old woman from the Kingdom of Saudi Arabia who had Fontan surgery and who had four successful pregnancies and multiple miscarriages. She delivered live, low birth weight neonates. CONCLUSION: This report provides an anecdotal evidence that pregnancy can be tolerated in an adequate Fontan patient with successful outcomes.

Here, we sought to identify strain-specific functional correlates with IBD outcomes. METHODS: We performed metagenomic sequencing of monthly stool samples from 20 IBD patients and 12 controls (266 total samples). These were taxonomically profiled with MetaPhlAn2 and functionally profiled using HUMAnN2. Differentially abundant species were identified using MaAsLin and strain-specific pangenome haplotypes were analyzed using PanPhlAn. RESULTS: We found a significantly higher abundance in patients of facultative anaerobes that can tolerate the increased oxidative stress of the IBD gut. We also detected dramatic, yet transient, blooms of Ruminococcus gnavus in IBD patients, often co occurring with increased disease activity. We identified two distinct clades of R. gnavus strains, one of which is enriched in IBD patients. To study functional differences between these two clades, we augmented the R. gnavus pangenome by sequencing nine isolates from IBD patients. We identified 199 IBD-specific, strain-specific genes involved in oxidative stress responses, adhesion, iron acquisition, and mucus utilization, potentially conferring an adaptive advantage for this R. gnavus clade in the IBD gut. CONCLUSIONS: This study adds further evidence to the hypothesis that increased oxidative stress may be a major factor shaping the dysbiosis of the microbiome observed in IBD and suggests that R. gnavus may be an important member of the altered gut community in IBD.

AB - BACKGROUND: Although mycobacterial glycolipids are among the first-line molecules involved in host-pathogen interactions, their contribution in virulence remains incomplete. Mycobacterium marinum is a waterborne pathogen of fish and other ectotherms, closely related to Mycobacterium tuberculosis. Since it causes tuberculosis-like systemic infection it is widely used as a model organism for studying the pathogenesis of tuberculosis. It is also an occasional opportunistic human pathogen. The M. marinum surface-exposed lipooligosaccharides (LOS) are immunogenic molecules that participate in the early interactions with macrophages and modulate the host immune system. Four major LOS species, designated LOS-I to LOS-IV, have been identified and characterized in M. marinum. Herein, we investigated the interactions between a panel of defined M. marinum LOS mutants that exhibited various degrees of truncation in the LOS structure, and human derived THP-1 macrophages to address the potential of LOSs to act as pro- or avirulence factors. RESULTS: A moderately truncated LOS structure did not interfere with M. marinum invasion. However, a deeper shortening of the LOS structure was associated with increased entry of M. marinum into host cells and increased elimination of the bacilli by the macrophages. These effects were dependent on Toll-like receptor 2. CONCLUSION: We provide the first evidence that LOSs inhibit the interaction between mycobacterial cell wall ligands and appropriate macrophage pattern recognition receptors, affecting uptake and elimination of the bacteria by host phagocytes. PMID- 29183334 TI - Depressive symptoms following natural disaster in Korea: psychometric properties of the Center for Epidemiologic Studies Depression Scale. AB - BACKGROUND: Depressive symptoms have been recognized as one of the most frequent complaints among natural disaster survivors. One of the most frequently used self report measures of depressive symptoms is the Center for Epidemiologic Studies Depression Scale (CES-D). To our knowledge, no study has yet examined the factor structure, reliability, and validity of the CES-D in a sample of natural disaster survivors. Thus, the present study investigated the factor structure, reliability, and validity of a Korean language version of the CES-D (KCES-D) for natural disaster survivors. METHODS: We utilized two archived datasets collected independently for two different periods in 2008 in the same region of Korea (n = 192 for sample 1; n = 148 for sample 2). Participants were survivors of torrential rains in the mid-eastern region of the Korean peninsula. For analysis, Samples 1 and 2 were merged (N = 340). Confirmatory factor analysis was performed to evaluate the one-factor model, the four-factor model, and the bi-factor models, as well as the second-order factor model. Composite reliability was computed to examine the internal consistency of the KCES-D total and subscale scores. Finally, Pearson's r was computed to examine the relationship between the KCES-D and the trauma-related measures. RESULTS: The four-factor model provided the best fit to the data among the alternatives. The KCES-D showed adequate internal consistency, except for the 'interpersonal difficulties' subscale. Also regarding concurrent validity, weak to moderate positive correlations were observed between the KCES-D and the trauma-related measures. CONCLUSIONS: The results support the four-factor model and indicate that the KCES-D has adequate psychometric properties for natural disaster survivors. If these findings are further confirmed, the KCES-D can be used as a useful, rapid, and inexpensive screening tool for assessing depressive symptoms in natural disaster survivors. PMID- 29183335 TI - Evaluating medical convenience in ethnic minority areas of Southwest China via road network vulnerability: a case study for Dehong autonomous prefecture. AB - BACKGROUND: Southwest China is home to more than 30 ethnic minority groups. Since most of these populations reside in mountainous areas, convenient access to medical services is an important metric of how well their livelihoods are being protected. METHODS: This paper proposes a medical convenience index (MCI) and computation model for mountain residents, taking into account various conditions including topography, geology, and climate. Data on road networks were used for comprehensive evaluation from three perspectives: vulnerability, complexity, and accessibility. The model is innovative for considering road network vulnerability in mountainous areas, and proposing a method of evaluating road network vulnerability by measuring the impacts of debris flows based on only links. The model was used to compute and rank the respective MCIs for settlements of each ethnic population in the Dehong Dai and Jingpo Autonomous Prefecture of Yunnan Province, in 2009 and 2015. Data on the settlements over the two periods were also used to analyze the spatial differentiation of medical convenience levels within the study area. RESULTS: The medical convenience levels of many settlements improved significantly. 80 settlements were greatly improved, while another 103 showed slight improvement.Areas with obvious improvement were distributed in clusters, and mainly located in the southwestern part of Yingjiang County, northern Longchuan County, eastern Lianghe County, and the region where Lianghe and Longchuan counties and Mang City intersect. CONCLUSIONS: Development of the road network was found to be a major contributor to improvements in MCI for mountain residents over the six-year period. PMID- 29183336 TI - Oncological outcome of complete response after neoadjuvant chemotherapy for breast conserving surgery: a systematic review and meta-analysis. AB - BACKGROUND: With limited sample sizes and single-institution designs, how complete response (CR) after neoadjuvant chemotherapy (NAC) influences breast conserving surgery (BCS) and its value in prognosis are not clear. METHODS: A systematic research review was conducted using electronic database. The rate of clinical complete response (cCR) in BCS after NAC and these pathological CR (PCR) and non-pCR BCS patients' local recurrence-free survival (LRFS), distance recurrence-free survival (DRFS), overall survival (OS), and disease-free survival (DFS) rates were collected. A pooled analysis was performed using a fixed or random effects model and a Q test to determine heterogeneity. RESULTS: Sixteen studies with a total of 4639 patients were included. The pooled data revealed that cCR patients compared with non-cCR patients had significantly higher rates of BCS, with a summary estimate odds ratios (OR) of 4.54 (95% CI 2.03-10.17). The pooled data revealed that BCS patients who achieved pCR after NAC had significantly lower rates of LRFS (RR = 0.59, 95% CI 0.38-0.92) and DRFS (RR = 0.27, 95% CI 0.13-0.55). Better DFS (RR = 0.09, 95% CI 0.04-0.25) and OS (RR = 0.36, 95% CI 0.03-3.90) were also seen, but OS was not significantly different. CONCLUSIONS: The rate of successful BCS is higher in the cCR group than in the non-cCR group, means cCR after NAC can encourage patients to receive BCS. The achievement of pCR after NAC in BCS patients was associated with a good prognosis in terms of LRFS and DRFS, but its value in DFS and OS requires further investigation. PMID- 29183337 TI - Unconscious physiological response of healthy volunteers to dynamic respiration synchronized couch motion. AB - BACKGROUND: Intrafractional motion can be a substantial uncertainty in precision radiotherapy. Conventionally, the target volume is expanded to account for the motion. Couch-tracking is an alternative, where the patient is moved to compensate for the tumor motion. However, the couch motion may influence the patient's stress and respiration behavior decreasing the couch-tracking effectiveness. METHODS: In total, 100 volunteers were positioned supine on a robotic couch, which moved dynamically and respiration synchronized. During the measurement, the skin conductivity, the heartrate, and the gaze location were measured indicating the volunteer's stress. Volunteers rated the subjective motion sickness using a questionnaire. The measurement alternated between static and tracking segments (three cycles), each 1 min long. RESULTS: The respiration amplitude showed no significant difference between tracking and static segments, but decreased significantly from the first to the last tracking segment (p < 0.0001). The respiration frequency differed significantly between tracking and static segments (p < 0.0001), but not between the first and the last tracking segment. The physiological parameters and the questionnaire showed mild signals of stress and motion sickness. CONCLUSION: Generally, people tolerated the couch motions. The interaction between couch motion and the patient's breathing pattern should be considered for a clinical implementation. TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov (NCT02820532) and the Swiss national clinical trials portal ( SNCTP000001878 ) on June 20, 2016. PMID- 29183338 TI - Optimization of PCR conditions for amplifying an AT-rich amino acid transporter promoter sequence with high number of tandem repeats from Arabidopsis thaliana. AB - OBJECTIVE: The aim of the present study is to optimize the PCR conditions required to amplify the promoter sequence of an amino acid transporter having an AT-rich base composition with a high number of tandem repeats. RESULT: Results show that successful amplification can be achieved by performing a 2-step PCR at a lower extension temperature of 65 degrees C for an increased extension period of 1.5 min/kb, with MgCl2 concentration ranging from 2.5 to 3.0 mM. The results also suggest that the DNA concentration of about 25-30 ng/ul was essential to achieve this amplification. PMID- 29183339 TI - Effect of EMG-triggered neuromuscular electrical stimulation with bilateral arm training on hemiplegic shoulder pain and arm function after stroke: a randomized controlled trial. AB - BACKGROUND: Hemiplegic shoulder pain is a frequent complication after stroke, leading to limited use of the affected arm. Neuromuscular electrical stimulation (NMES) and transcutaneous electrical nerve stimulation (TENS) are two widely used interventions to reduce pain, but the comparative efficacy of these two modalities remains uncertain. The purpose of this research was to compare the immediate and retained effects of EMG-triggered NMES and TENS, both in combination with bilateral arm training, on hemiplegic shoulder pain and arm function of stroke patients. METHODS: A single-blind, randomized controlled trial was conducted at two medical centers. Thirty-eight patients (25 males and 13 females, 60.75 +/- 10.84 years old, post stroke duration 32.68 +/- 53.07 months) who had experienced a stroke more than 3 months ago at the time of recruitment and hemiplegic shoulder pain were randomized to EMG-triggered NMES or TENS. Both groups received electrical stimulation followed by bilateral arm training 3 times a week for 4 weeks. The primary outcome measures included a vertical Numerical Rating Scale supplemented with a Faces Rating Scale, and the short form of the Brief Pain Inventory. The secondary outcome measures were the upper-limb subscale of the Fugl-Meyer Assessment, and pain-free passive shoulder range of motion. All outcomes were measured pretreatment, post-treatment, and at 1-month after post treatment. Two-way mixed repeated measures ANOVAs were used to examine treatment effects. RESULTS: Compared to TENS with bilateral arm training, the EMG-triggered NMES with bilateral arm training was associated with lower pain intensity during active and passive shoulder movement (P =0.007, P =0.008), lower worst pain intensity (P = 0.003), and greater pain-free passive shoulder abduction (P =0.001) and internal rotation (P =0.004) at follow-up. Both groups improved in pain at rest (P =0.02), pain interference with daily activities, the Fugl-Meyer Assessment, and pain-free passive shoulder flexion and external rotation post treatment (P < 0.001) and maintained the improvement at follow-up (P < 0.001), except for resting pain (P =0.08). CONCLUSIONS: EMG-triggered NMES with bilateral arm training exhibited greater immediate and retained effects than TENS with bilateral arm training with respect to pain and shoulder impairment for chronic and subacute stroke patients with hemiplegic shoulder pain. TRIAL REGISTRATION: NCT01913509 . PMID- 29183340 TI - Mapping outdoor habitat and abnormally small newborns to develop an ambient health hazard index. AB - BACKGROUND: The geography of where pregnant mothers live is important for understanding outdoor environmental habitat that may result in adverse birth outcomes. We investigated whether more babies were born small for gestational age or low birth weight at term to mothers living in environments with a higher accumulation of outdoor hazards. METHODS: Live singleton births from the Alberta Perinatal Health Program, 2006-2012, were classified according to birth outcome, and used in a double kernel density estimation to determine ratios of each outcome per total births. Individual and overlay indices of spatial models of 136 air emissions and 18 land variables were correlated with the small for gestational age and low birth weight at term, for the entire province and sub provincially. RESULTS: There were 24 air substances and land sources correlated with both small for gestational age and low birth weight at term density ratios. On the provincial scale, there were 13 air substances and 2 land factors; sub provincial analysis found 8 additional air substances and 1 land source. CONCLUSION: This study used a combination of multiple outdoor variables over a large geographic area in an objective model, which may be repeated over time or in other study areas. The air substance-weighted index best identified where mothers having abnormally small newborns lived within areas of potential outdoor hazards. However, individual air substances and the weighted index provide complementary information. PMID- 29183341 TI - Kinetics and dissolution of intratracheally administered nickel oxide nanomaterials in rats. AB - BACKGROUND: The toxicokinetics of nanomaterials are an important factor in toxicity, which may be affected by slow clearance and/or distribution in the body. METHODS: Four types of nickel oxide (NiO) nanoparticles were single administered intratracheally to male F344 rats at three doses of 0.67-6.0 mg/kg body weight. The rats were sacrificed under anesthesia and the lung, thoracic lymph nodes, bronchoalveolar lavage fluid, liver, and other organs were sampled for Ni burden measurement 3, 28, and 91 days post-administration; Ni excretion was measured 6 and 24 h after administration. Solubility of NiO nanoparticles was determined using artificial lysosomal fluid, artificial interstitial fluid, hydrogen peroxide solution, pure water, and saline. In addition, macrophage migration to trachea and phagosome-lysosome-fusion rate constants were estimated using pulmonary clearance and dissolution rate constants. RESULTS: The wire-like NiO nanoparticles were 100% dissolved by 24 h when mixed with artificial lysosomal fluid (dissolution rate coefficient: 0.18/h); spherical NiO nanoparticles were 12% and 35% dissolved after 216 h when mixed with artificial lysosomal fluid (1.4 * 10-3 and 4.9 * 10-3/h). The largest irregular-shaped NiO nanoparticles hardly dissolved in any solution, including artificial lysosomal fluid (7.8 * 10-5/h). Pulmonary clearance rate constants, estimated using a one compartment model, were much higher for the NiO nanoparticles with a wire-shape (0.069-0.078/day) than for the spherical and irregular-shaped NiO nanoparticles (0-0.012/day). Pulmonary clearance rate constants of the largest irregular-shaped NiO nanoparticles showed an inverse correlation with dose. Translocation of NiO from the lungs to the thoracic lymph nodes increased in a time- and dose dependent manner for three spherical and irregular-shaped NiO nanoparticles, but not for the wire-like NiO nanoparticles. Thirty-five percent of the wire-like NiO nanoparticles were excreted in the first 24 h after administration; excretion was 0.33-3.6% in that time frame for the spherical and irregular-shaped NiO nanoparticles. CONCLUSION: These findings suggest that nanomaterial solubility differences can result in variations in their pulmonary clearance. Nanoparticles with moderate lysosomal solubility may induce persistent pulmonary inflammation. PMID- 29183342 TI - The pH stability of foot-and-mouth disease virus. AB - : ?: This review summarized the molecular determinants of the acid stability of FMDV in order to explore the uncoating mechanism of FMDV and improve the acid stability of vaccines. BACKGROUND: The foot-and-mouth disease virus (FMDV) capsid is highly acid labile and tends to dissociate into pentameric subunits at acidic condition to release viral RNA for initiating virus replication. However, the acid stability of virus capsid is greatly required for the maintenance of intact virion during the process of virus culture and vaccine production. The conflict between the acid lability in vivo and acid stability in vitro of FMDV capsid promotes the selection of a series of amino acid substitutions which can confer resistance to acid-induced FMDV inactivation. In order to explore the uncoating activity of FMDV and enhance the acid stability of vaccines, we summarized the available works about the pH stability of FMDV. In this review, we analyzed the intrinsic reasons for the acid instability of FMDV from the structural and functional aspects. We also listed all substitutions obtained by different research methods and showed them in the partial capsid of FMDV. We found that a quadrangle region in the viral capsid was the place where a great many pH sensitive residues were distributed. As the uncoating event of FMDV is dependent on the pH-sensitive amino acid residues in the capsid, this most pH-sensitive position indicates a potential candidate location for RNA delivery triggered by the acid-induced coat disassociation. SHORT CONCLUSION: This review provided an overview of the pH stability of FMDV. The study of pH stability of FMDV not only contributes to the exploration of molecule and mechanism information for FMDV uncoating, but also enlightens the development of FMDV vaccines, including the traditionally inactivated vaccines and the new VLP (virus-like particle) vaccines. PMID- 29183343 TI - Primary and metastatic cardiac tumors: echocardiographic diagnosis, treatment and prognosis in a 15-years single center study. AB - BACKGROUND: The frequency of primary cardiac tumors is rare at about 0.3% by autopsy. Our objective was to investigate the characteristics and locations of cardiac tumors and to provide a prognostic analysis in our hospital. METHODS: We collected data on 95 patients with echocardiographic diagnosis or detection of cardiac tumors in a prospective analysis from 1999 to 2014. The median follow-up period was 43 months (0.5-183 months). RESULTS: The subjects included 56 men and 39 women with a mean age of 65 years. Clinical diagnosis revealed primary tumors in 61 patients (64%) and secondary metastatic tumors in 34 patients (36%). In the 61 patients, 41 patients (67%) underwent surgery and tissue samples were obtained. Of these 41 patients, benign tumors were found in 30 cases (73%). One patient (2%) was diagnosed with thrombus. Among the benign tumors, myxoma (67%) was the most common type followed by papillary fibroelastoma (23%). The most common site was the left atrium (35%) followed by the right atrium (25%). Primary malignant tumors were diagnosed in 10 cases (24%), including 6 angiosarcomas, 3 lymphomas, and 1 leiomyosarcoma. The diagnostic accuracy of echocardiography was 80%. The patients with benign tumors were all alive at the end of the follow-up period. In contrast, 7 patients with malignant tumors died (70%) (p < 0.0001). CONCLUSIONS: Our data is in line with previous literature. Our study also suggests the necessity of extending our knowledge of the characteristics of cardiac tumors for diagnosis. PMID- 29183344 TI - Oral verruciform xanthoma and erythroplakia associated with chronic graft-versus host disease: a rare case report and review of the literature. AB - BACKGROUND: Oral verruciform xanthoma is an uncommon benign lesion. Although oral verruciform xanthoma occurs in healthy individuals, it has been also reported in association with some inflammatory conditions. The aim of this study is to report a case of oral verruciform xanthoma associated with chronic graft-versus-host disease and to review the literature on this topic. CASE PRESENTATION: A 47-year old Caucasian male presented to the Sector of Oral Medicine "V. Margiotta", University Policlinic "P. Giaccone" of Palermo complaining of a mass on the gingiva. He first noticed the painless mass 1 year ago. He reported to have undergone allogenic hematopoietic stem cell transplantation 15 years ago for acute lymphoblastic leukaemia. Intraoral examination revealed a well circumscribed, sessile yellowish and verrucous nodule upon canine, multiple yellowish and verrucous nodules on the hard palate, yellowish and verrucous nodules on left buccal mucosa. In addiction an area of white striae in a reticular pattern with erythema and ulceration was present on the dorsum of the tongue. This lesion was consistent with a known history of oral chronic graft versus host disease. Moreover, we observed a suspected area of oral erythroplakia yet on the dorsum of the tongue. In biopsy specimen of hard palate histopathological examination revealed a diagnosis of verrucous xanthoma of the oral cavity; in addiction in biopsy specimen of the dorsum of the tongue revealed the presence of erythroplakia with high grade dysplasia. CONCLUSION: Verruciform xanthoma of the oral cavity associated with chronic graft-versus-host disease is a rare condition with a usually benign clinical course but malignant transformation has been described in association with oral potential malignant disorder (e.g. chronic graft versus host disease, erythroplakia). Very rare cases showed association with oral chronic graft versus-host-disease. To date, only eight cases were published in the world literature. Therefore it could be important follow up patients also for oral verruciform xanthoma onset. PMID- 29183345 TI - Primary tracheal schwannoma a review of a rare entity: current understanding of management and followup. AB - BACKGROUND: Neurogenic tumors of the tracheobronchial tree are extremely rare and include neurofibroma and schwannoma. We report a case of primary recurrent tracheal schwannoma causing obstructive airway symptoms. CASE PRESENTATION: A 60 year-old man presented with obstructive airway symptoms due to recurrent tracheal schwannoma. Due the recurrence, size of the tumor and low surgical risk, the patient was treated with tracheal resection. CONCLUSION: Primary endotracheal neurogenic tumors are extremely rare, but one should consider them in the differential diagnosis of persistent upper airway symptoms. While endoscopic therapies recur nearly a quarter of the time, surgical resections do not have any recorded recurrences. PMID- 29183346 TI - ALX4, an epigenetically down regulated tumor suppressor, inhibits breast cancer progression by interfering Wnt/beta-catenin pathway. AB - BACKGROUND: ALX4 is a paired-like homedomain transcription factor mainly expressed in the mesenchymal compartment of variety of developing tissues, but its functions, regulation mechanisms and clinical values in breast cancer remains unclear. METHODS: The expression of ALX4 in breast cancer cell lines and patients' tissues were detected by RT-PCR, qPCR and western blot. Furthermore TCGA database was applied to confirm these results. MSP and BSP methods were used to assess the methylation of ALX4 promoter region. In vitro proliferation, metastasis and in vivo nude mice model were used to evaluate the anti-tumor effect of ALX4 on breast cancer cell lines. Luciferase reporter assay, western blot and TCGA database were used to investigate the tumor suppression mechanisms of ALX4. TMA of 142 breast patients was generated to evaluate the clinical significance of ALX4. RESULTS: Expression analysis revealed that ALX4 expression is down regulated in breast cancer cell lines and tissues. MSP study showed that the promoter region of ALX4 was hyper-methylated 100% (3/3) in breast cancer cell lines and 69.44% (75/108) in primary breast tumors tissues while 0% (0/8) in normal breast tissues. 5-aza-dc de-methylation treatment restored ALX4 expression in breast cancer cell lines. Functional studies showed that ectopic expression of ALX4 in breast cancer cells inhibited cell proliferation, metastasis in vitro and in vivo. Mechanism study found that ALX4 exerted its anti-tumor function by suppressing the Wnt/beta-catenin pathway through promoting the phosphorylation degradation of beta-catenin in a GSK3beta dependent manner. Clinically multivariate analysis showed that ALX4 expression was an independent favorable prognostic factor in breast cancer patients. CONCLUSIONS: We reveal for the first time that ALX4 acts as a novel functional tumor suppressor inactivated by DNA methylation and is an independent prognostic factor in breast cancer. PMID- 29183348 TI - Influence of breast compression pressure on the performance of population-based mammography screening. AB - BACKGROUND: In mammography, breast compression is applied to reduce the thickness of the breast. While it is widely accepted that firm breast compression is needed to ensure acceptable image quality, guidelines remain vague about how much compression should be applied during mammogram acquisition. A quantitative parameter indicating the desirable amount of compression is not available. Consequently, little is known about the relationship between the amount of breast compression and breast cancer detectability. The purpose of this study is to determine the effect of breast compression pressure in mammography on breast cancer screening outcomes. METHODS: We used digital image analysis methods to determine breast volume, percent dense volume, and pressure from 132,776 examinations of 57,179 women participating in the Dutch population-based biennial breast cancer screening program. Pressure was estimated by dividing the compression force by the area of the contact surface between breast and compression paddle. The data was subdivided into quintiles of pressure and the number of screen-detected cancers, interval cancers, false positives, and true negatives were determined for each group. Generalized estimating equations were used to account for correlation between examinations of the same woman and for the effect of breast density and volume when estimating sensitivity, specificity, and other performance measures. Sensitivity was computed using interval cancers occurring between two screening rounds and using interval cancers within 12 months after screening. Pair-wise testing for significant differences was performed. RESULTS: Percent dense volume increased with increasing pressure, while breast volume decreased. Sensitivity in quintiles with increasing pressure was 82.0%, 77.1%, 79.8%, 71.1%, and 70.8%. Sensitivity based on interval cancers within 12 months was significantly lower in the highest pressure quintile compared to the third (84.3% vs 93.9%, p = 0.034). Specificity was lower in the lowest pressure quintile (98.0%) compared to the second, third, and fourth group (98.5%, p < 0.005). Specificity of the fifth quintile was 98.4%. CONCLUSION: Results suggest that if too much pressure is applied during mammography this may reduce sensitivity. In contrast, if pressure is low this may decrease specificity. PMID- 29183347 TI - The effect of an intensive smoking cessation intervention on disease activity in patients with rheumatoid arthritis: study protocol for a randomised controlled trial. AB - BACKGROUND: Rheumatoid arthritis (RA) is a chronic, inflammatory rheumatic disease with the potential to induce significant disability. Patients with RA are at increased risk of cardiovascular diseases (CVD). Smokers with RA tend to experience more pain and fatigue, higher disease activity, more erosive joint destruction and a lower health-related quality of life (HR-QoL) than non-smokers. It remains to be determined whether these effects can be reduced by smoking cessation. This randomised controlled trial (RCT) in patients with RA aims to examine the effect of intensive smoking cessation intervention (motivational counselling combined with tailored nicotine replacement therapy) versus standard care on smoking cessation, and consequently on disease activity. Secondary objectives are to explore the effect on flare, risk factors for CVD, lung function, physical function, HR-QoL, pain and fatigue in patients with RA. METHODS: This will be a multicentre, open label, two arm, parallel group, RCT, including 150 daily smokers with RA, being in remission or having low-moderate disease activity (DAS28 <= 5.1). The intervention group (n = 75) will receive five counselling sessions with a trained smoking cessation counsellor based on the principles of motivational counselling. Furthermore, intervention patients will be offered nicotine replacement therapy tailored to individual needs. Participants randomised to the control group will receive standard care. The co primary outcome is a hierarchical endpoint, which will be evaluated at 3 months follow-up and will include (1) self-reported smoking cessation biochemically validated by exhaled carbon monoxide and (2) achievement of EULAR clinical response (an improvement in DAS28 of > 0.6). Follow-up visits will be performed at 3, 6 and 12 months post-intervention. DISCUSSION: This trial will reveal whether intensive smoking cessation counselling helps smokers with RA to achieve continuous smoking cessation and whether, as a concomitant benefit, it will reduce their RA disease activity. The trial aims to generate high quality evidence for the feasibility of a health promotion intervention for smokers with RA. TRIAL REGISTRATION: ClinicalTrials.gov, identifier: NCT02901886 .

PMID- 29183349 TI - A Drosophila genetic model of nephrolithiasis: transcriptional changes in response to diet induced stone formation. AB - BACKGROUND: Urolithiasis is a significant healthcare issue but the pathophysiology of stone disease remains poorly understood. Drosophila Malpighian tubules were known to share similar physiological function to human renal tubules. We have used Drosophila as a genetic model to study the transcriptional response to stone formation secondary to dietary manipulation. METHODS: Wild-type male flies were raised on standard medium supplemented with lithogenic agents: control, sodium oxalate (NaOx) and ethylene glycol (EG). At 2 weeks, Malpighian tubules were dissected under polarized microscope to visualize crystals. The parallel group was dissected for RNA extraction and subsequent next-generation RNA sequencing. RESULTS: Crystal formation was visualized in 20%(+/-2.2) of flies on control diet, 73%(+/-3.6) on NaOx diet and 84%(+/-2.2) on EG diet. Differentially expressed genes were identified in flies fed with NaOx and EG diet comparing with the control group. Fifty-eight genes were differentially expressed (FDR <0.05, p < 0.05) in NaOx diet and 20 genes in EG diet. The molecular function of differentially expressed genes were assessed. Among these, Nervana 3, Eaat1 (Excitatory amino acid transporter 1), CG7912, CG5404, CG3036 worked as ion transmembrane transporters, which were possibly involved in stone pathogenesis. CONCLUSIONS: We have shown that by dietary modification, stone formation can be manipulated and visualized in Drosophila Malpighian tubules. This genetic model could be potentially used to identify the candidate genes that influence stone risk hence providing more insight to the pathogenesis of human stone disease. PMID- 29183350 TI - Sequential activation of the AKT pathway in human osteoblasts treated with Oscarvit: a bioactive product with positive effect both on skeletal pain and mineralization in osteoblasts. AB - BACKGROUND: Oscarvit (OSC) is an in-house preparation consisting of calcium, magnesium, phosphorus, strontium, Vitamin D, and eggshell membrane hydrolysate containing naturally occurring glycosaminoglycans and sulfated glycoproteins. OSC has been used both in an open-label human study and in vitro in osteoblasts. METHODS: Fifteen patients divided into three groups received oral OSC 0.6 g three times daily for 20 days. The main outcome measures were regional skeletal pain over the treatment period. For the in vitro experiments eight primary human osteoblasts cultures were established from trabecular bone, six of them from the femoral head, and two from the tibia. Cells were cultured for five to 20 days in the presence of 20 MUg/ml OSC. Immunocytochemistry and RT-PCR were used to detect molecular alterations involved in the mineralization process. Calcium concentration was measured by means of a colorimetric assay and cell viability was analyzed using the LDH cytotoxicity assay. To investigate whether the osteoblasts response to OSC is associated with signaling processes the ERK1/2 and AKT signal transduction pathways were analyzed. RESULTS: Open label human study: OSC, 0.6 g three times daily, resulted in a significant positive effect on pain alleviation of 42% after 5 days (p < 0.001), 57% after 10 days and 68% after 20 days (p < 0.0001; for both time points), with no side-effects being reported. In vitro analysis: In osteoblasts, growing in OSC-supplemented media significant overexpression of bone gamma-carboxylglutamic acid-containing protein, secreted phosphoprotein-1, integrin binding sialoprotein, and dentin matrix phosphoprotein genes could be detected when compared to control osteoblasts grown in the absence of OSC. Moreover, OSC-treated osteoblasts produced over the study period vast extracellular calcium deposits without any loss of cellular integrity or signs of cellular toxicity. In addition OSC promotes osteoblast differentiation and activates the AKT signaling pathway. CONCLUSION: This open label study provides preliminary evidence of the efficacy of OSC. Despite the limitations (small heterogeneous patient group) the findings can be viewed as a necessary investigation that supports further clinical trials with a double-blind controlled design. Experiments at cellular and molecular level provide supplementary information about OSC that increases mineralization in osteoblasts and activation of the AKT pathway.

AB - BACKGROUND: Thyroid hemorrhage is considered to be an uncommon complication following blunt trauma to the neck. This condition is potentially life threatening due to airway compression and may therefore require emergency airway management and surgical intervention in some cases. CASE PRESENTATION: We present the case of a 52-year-old woman who experienced a traumatic thyroid gland rupture (right lobe) with subsequent active arterial bleeding from branches of the inferior thyroid artery. On the same day, the patient presented to our emergency department with a painful swelling of the neck with an inspiratory stridor and hoarseness a few hours after a cycling accident. A right hemithyroidectomy was performed. The postoperative course was uneventful. We identified 33 additional cases published in English literature within the last 30 years, reporting blunt trauma to the neck with hemorrhagic complication of the thyroid gland. We provide a systematic review and particularly consider the aspects of endocrine surgery. CONCLUSION: The treatment approach for patients with blunt thyroid trauma should be dependent on the extent of the thyroid injury. Patients with tracheal compression, active bleeding and increasing hoarseness/shortness of breath require emergency airway control and often surgical exploration for hemorrhage control followed by resection of the ruptured thyroid. Importantly, in contrast to routine thyroid surgery, no electromyographic endotracheal tube is used during emergency intubation. Exchange of an endotracheal tube should be carefully evaluated due to difficult airway management in this setting. For protection against double-sided recurrent nerve palsy and postoperative hypoparathyroidism, a unilateral approach is preferable whenever possible.

AB - OBJECTIVE: Campylobacter spp. and Helicobacter spp. are rare but important causes of bacteremia in humans. Distinguishing these bacteria is complicated because of their similar phenotypic profiles. We conducted clinical and microbiological investigations of Campylobacter spp. or Helicobacter spp. bacteremia. Patients diagnosed with bacteremia from 2008 to 2014 were included. The clinical and microbiological characteristics of Campylobacter spp. and Helicobacter spp. bacteremia were compared. The BACTEC system was used in blood cultures. A receiver operating characteristic curve was plotted based on the time to blood culture positivity. RESULTS: Sixteen cases of Helicobacter spp. bacteremia (patient age: 61 +/- 18 years) and 14 cases of Campylobacter spp. bacteremia (patient age: 49 +/- 21 years) were identified. Median time to blood culture positivity was longer for the Helicobacter spp. cases than the Campylobacter spp. cases (91.4 h vs 55.3 h, p < 0.01). A time to blood culture positivity > 75 h predicted Helicobacter spp. bacteremia with a sensitivity of 0.88 and a specificity of 0.93 (area under the receiver operating characteristic curve of 0.90). In conclusion, a time to blood culture positivity was useful in distinguishing Helicobacter spp. bacteremia from Campylobacter spp. bacteremia. PMID- 29183352 TI - Risk factors for difficulty of laparoscopic cholecystectomy in grade II acute cholecystitis according to the Tokyo guidelines 2013. AB - BACKGROUND: The Tokyo Guidelines 2013 classifies acute cholecystitis (AC) into three grades and recommends appropriate therapy for each grade. For grade II AC, either early laparoscopic cholecystectomy (LC) or percutaneous transhepatic gallbladder drainage (PTGBD) should be performed. This study aimed to identify the risk factors for difficulty of LC for treating grade II AC. METHODS: Totally, 122 patients who underwent LC for grade II AC were enrolled and divided into difficult LC (DLC) and nondifficult LC (NDLC) groups. The DLC group included patients who experienced one of the following conditions: conversion from LC to open cholecystectomy, operating time >= 180 min, or blood loss >=300 ml. Preoperative characteristics and postoperative outcomes were analyzed. RESULTS: In univariate analysis, risk factors included male sex, interval between symptom onset and admission, interval between symptom onset and LC, and anticoagulant therapy. The incidence of postoperative complications was higher in the DLC group than in the NDLC group (23.5% vs. 4.6%, p = 0.0016). According to receiver operating characteristic curves, the optimal cutoff value was calculated, and multivariate analysis showed that male sex [odds ratio (OR), 5.76; 95% confidence interval (CI), 1.979-19.51; p = 0.0009) and interval between symptom onset and LC of over 96 h (OR, 6.32; 95% CI, 2.126-20.15; p = 0.0009) were independent risk factors for difficulty of LC. CONCLUSIONS: In patients with grade II AC, LC was technically difficult when performed over 96 h after symptom onset. Moreover, male sex was a risk factor. Therefore, PTGBD should be considered in these patients. PMID- 29183354 TI - Motives for change of first-line antiretroviral therapy regimens in an unselected cohort of HIV/AIDS patients at a major referral centre in South-west Cameroon. AB - OBJECTIVE: The rapid scale-up of antiretroviral therapy (ART) coverage in sub Saharan Africa has encountered the challenge of maintaining international clinical standards of ART utilization and change of ART regimens. In Cameroon, scarce reports have documented the motives for change of ART. This study had as objective to investigate the reasons for switch in ART through a secondary analysis and descriptive synthesis of data from a cross-sectional study at the Limbe Regional Hospital. RESULTS: One hundred participants were included. Their mean age was 40.2 +/- 8.0 years and 70% of them were females. The median duration of ART use was 60 months. Zidovudine-Lamivudine-Nevirapine regimen was received by 83% of patients while the Stavudine-Lamivudine-Nevirapine regimen had the highest median duration of use (58 months). Most patients had experienced changes in ART (especially from Stavudine-Lamivudine-Nevirapine regimen) with the chief reason being unavailability of their previous regimens. Four patients had their ART changed due to active tuberculosis, 4 due to pregnancy and 7 due to ART toxicity (4 and 3 for peripheral neuropathy and lipodystrophy respectively). In conclusion, shortages in ART hugely influenced switch in regimens. In such a context, modifications in ART possibly deviate from guidelines with resultant sub optimal therapy and enhanced drug resistance. PMID- 29183355 TI - Intestinal parasitosis and anaemia among patients in a Health Center, North Ethiopia. AB - OBJECTIVE: The aim of this cross-sectional study was to determine the magnitude of intestinal parasitosis and anaemia in a Health Center, North Ethiopia. RESULTS: A total of 427 outpatients were enrolled and the median age of the participants was 22 years. The prevalence of intestinal parasitosis was 143 (33.5%). Age, place of residence and occupation were significantly associated with intestinal parasitosis. When we see parasite specific factors, significant associations were observed for source of drinking water (P = 0.02), age (P < 0.001) and family size (P = 0.003), respectively with Entameba histolytica, Hookworm and Giardia lamblia infections. The overall prevalence of anaemia was 35 (8.2%). The mean haemoglobin concentration among the study participants was 12.8 mg/dl. The highest prevalence of anemia was recorded for the age group of 15-19 years (29.6%). The proportion of anemia among intestinal parasite -infected and non-infected participants was 10.7 and 7.0%, respectively. Study participants infected with S. stercoralis and hookworm were more likely to develop anaemia than the non- infected ones; AOR (adjusted odds ratio) = 5.3, 95% CI (1.01-27.4); P = 0.028 and AOR = 11.1, 95% CI (3.36-36.9); P = 0.000, respectively. PMID- 29183356 TI - Outcome of uncomplicated ureteric calculi managed with medical expulsive therapy in the outpatient clinic of a urology unit in Sri Lanka. AB - OBJECTIVE: Although medical expulsive therapy (MET) is shown to be effective for ureteric calculi, the optimum duration and the stone size suitable for MET are not well established yet. The objectives of the study were to determine the optimum duration and maximum stone size suitable for MET. RESULTS: All patients with radiologically confirmed uncomplicated ureteric calculi treated with MET using tamsulosin over a period of 6 months in the outpatient setting were followed up. There were 213 patients. 165 were men. Mean age was 42 years. At presentation 42 stones were in upper ureter (19.7%), 51 in mid ureter (23.9%), 120 in lower ureter (56.3%). The majority (82.7%) of stones were less than 10 mm. Seven stones (3.3%) were over 15 mm. Ninety-two (43.2%) patients had spontaneous passage of stones within 6-weeks of MET. Another 38.9% passed the stone within the next 6-weeks. Thirty-eight patients (17.8%) required surgery. Uncomplicated ureteric stones up to 10 mm can be given a trial of MET using tamsulosin which can be extended up to 12-weeks with a success rate over 92%. This may have substantial clinical and fiscal benefits by reducing the number of interventional procedures especially in resource-poor settings. PMID- 29183358 TI - Bacteriological aspects of chronic osteoarticular infections in adults: the influence of the osteosynthesis material. AB - BACKGROUND: The aim of this study is to establish the bacterial epidemiology of chronic osteoarticular infections in adults, to study the susceptibility of the isolated strains to antibiotics and to demonstrate the influence of osteosynthesis material thereon. PATIENTS AND METHODS: This is a retrospective study of 78 months, from January 2006 to June 2012, providing bacteriological samples from patients with osteitis and osteoarthritis in the Mohammed V military teaching hospital of Rabat. Isolation and identification of bacteria were made by bacteriological classical techniques. The antimicrobial susceptibility testing of the isolates was performed by disk diffusion agar method, as recommended by the Committee of the susceptibility of the French Society for Microbiology (CA-SFM). RESULTS: We collected 234 cases, 53% (n = 124) of patients without osteosynthesis material (group A) and 47% (n = 110) patients with osteosynthesis material (group B).We isolated 371 bacteria which 51.49 (n = 191) in group A and 48.51% (n = 180) in group B. Gram-positive cocci were the most frequent (n = 234), followed by the Gram-negative bacilli (n = 114) and the Gram-positive bacilli (n = 19). Our study shows that the rate of resistance to antibiotics in strains obtained from patients with osteosynthesis material is higher compared to those obtained from patients without osteosynthesis material. CONCLUSIONS: Chronic OA infection in adults is difficult to diagnose and treat. Its good management must be multidisciplinary. PMID- 29183357 TI - Automated telephone interventions for problematic alcohol use in clinical and population samples: a randomized controlled trial. AB - OBJECTIVE: The primary objective was to evaluate 6-month outcomes for brief and extensive automated telephony interventions targeting problematic alcohol use, in comparison to an assessment-only control group. The secondary objective was to compare levels of problematic alcohol use (hazardous, harmful or probable dependence), gender and age among study participants from clinical psychiatric and addiction outpatient settings and from population-based telephone helpline users and Internet help-seeker samples. RESULTS: The Alcohol Use Disorders Identification Test (AUDIT) was used for screening of problematic alcohol use and 6-month follow-up assessment. A total of 248 of help-seekers with at least hazardous use (AUDIT scores of >= 6/>= 8 for women/men) were recruited from clinical and general population settings. Minor recruitment group differences were identified with respect to AUDIT scores and age at baseline. One hundred and sixty persons (64.5%) did not complete the follow-up assessment. The attrition group had a higher proportion of probable dependence (71% vs. 56%; p = 0.025), and higher scores on the total AUDIT, and its subscales for alcohol consumption and alcohol problems. At follow up, within-group problem levels had declined across all three groups, but there were no significant between-group differences.

PMID- 29183359 TI - Acute on chronic bilateral subdural hematoma presenting with acute complete flaccid paraplegia and urinary retention mimicking an acute spinal cord injury: a case report. AB - BACKGROUND: A subdural hematoma refers to a collection of blood between the dura and the arachnoid membranes and is classified into acute, sub acute and chronic. Subdural hematoma has been referred to as the "great neurologic imitator" as it can mimic many neurological conditions. CASE PRESENTATION: Forty-three year old Sri Lankan female presented 2 weeks following traumatic head injury with bilateral flaccid complete paraplegia and urinary retention. Her non-contrast computer tomography of the brain revealed bilateral acute, chronic subdural hematomas. Both subdural hematomas were aspirated and she recovered completely. CONCLUSIONS: Chronic subdural hematoma can present in many different unusual ways including bilateral complete paraplegia and acute urinary retention mimicking acute spinal cord pathology. The exact mechanism of this clinical presentation is not clear and may be due to direct compression of the motor cortex to the falx or due to compression of the anterior cerebral artery due to subfalcine herniation. This case illustrates the importance of considering subdural hematoma as a rare cause for acute paraplegia and the importance of performing a computer tomography scan in traumatic brain injury when indicated. Failure to consider non-spinal causes of paraplegia results in potential mismanagement. According to our knowledge this is the first case report of acute on chronic subdural hematoma presenting as acute flaccid complete paraplegia with urinary retention. PMID- 29183360 TI - Misclassification of child body mass index from cut-points defined by rounded percentiles instead of Z-scores. AB - OBJECTIVE: To evaluate the misclassification resulting from the use of body mass index (BMI) cut-points defined by rounded percentiles instead of Z-scores in early childhood. Using data from the TARGet Kids primary care network we conducted a cross-sectional study among 5836 children < 6 years of age. The World Health Organization growth standards were used to calculate BMI-for-age Z-scores. BMI Z-score cut-points of < - 2.0, > 1.0, > 2.0, > 3.0 are recommended to define wasted, at risk of overweight, overweight and obese. However, rounded percentiles of the 3rd, 85th, 97th, and 99.9th are commonly used. Misclassification was calculated comparing the frequency distributions for BMI categories defined by rounded percentiles and Z-score cut-points. RESULTS: Using rounded percentiles, the proportion of children who were wasted, at risk of overweight, overweight, and obese was 4.2, 12.5, 4.3 and 0.8%, whereas the distribution using Z-scores was: 3.6, 13.8, 3.4 and 1.0%, respectively. Overall, 117 (2%) children were misclassified when using percentiles instead of Z-scores; however, 13% (33/245) of children who were wasted and 14% (8/57) of children who were obese were misclassified. Misclassification of child growth results from the use of cut points defined by rounded percentiles instead of Z-scores and limits comparability between studies.

AB - BACKGROUND: Naringenin (Nar), a common dietary flavonoid abundantly present in fruits, vegetables, and Chinese herbs, is believed to possess strong anti inflammatory properties and to modulate hepatic apolipoprotein and lipid synthesis. However, there are no reports describing Nar's effects on the hepatitis B virus protein X (HBx) -induced hepatic steatosis, and the detailed molecular mechanisms of the compound's effects are still unclear. METHODS: Nar was administered by oral gavage to HBx-transgenic mice from 4 to 6 weeks of age. Mice were sacrificed after 14 days of once-daily naringenin administration. Liver tissues and sera were collected for histopathology and biochemical analysis. RESULTS: Nar counteracted hepatic lipid accumulation and liver dysfunction in HBx transgenic mice. In addition, Nar significantly decreased expression of adipogenic and lipogenic genes in mice, suggesting that the compound may have therapeutic effects in the early stages of HBx-mediated hepatic steatosis. These results indicated that naringenin inhibits HBx-induced expression of hepatic adipogenic and lipogenic genes through suppression of HBx-induced gene expression, including decreases in the transcriptional activity of SREBP1c, LXRalpha, and PPARgamma in HBx-trangenic mice and HBx-transfected HepG2 cells. CONCLUSIONS: Results from this study suggested that Nar may serve as a therapeutic agent for preventing HBx-infected hepatic steatosis in humans. PMID- 29183362 TI - Unifying the functional diversity in natural and cultivated soils using the overall body-mass distribution of nematodes. AB - BACKGROUND: Sustainable use of our soils is a key goal for environmental protection. As many ecosystem services are supported belowground at different trophic levels by nematodes, soil nematodes are expected to provide objective metrics for biological quality to integrate physical and chemical soil variables. Trait measurements of body mass carried out at the individual level can in this way be correlated with environmental properties that influence the performance of soil biota. RESULTS: Soil samples were collected across 200 sites (4 soil types and 5 land-use types resulting in 9 combinations) during a long-term monitoring programme in the Netherlands and the functional diversity of nematode communities was investigated. Using three commonly used functional diversity indices applicable to single traits (Divergence, Evenness and Richness), a unified index of overall body-mass distribution is proposed to better illustrate the application of functional metrics as a descriptor of land use. Effects of land use and soil chemistry on the functional diversity of nematodes were demonstrated and a combination of environmental factors accounts for the low functional value of Scots Pine forest soils in comparison to the high functional value of heathland soils, whereas human factors account for the low functional and chemical values of arable fields. CONCLUSIONS: These findings show an unexpected high functional vulnerability of nematodes inhabiting clay-rich soils in comparison to sandy soils and support the notion that soil C:N ratio is a major driver of biodiversity. The higher the C:N ratio, the higher the overall diversity, as soil nematodes cope better with nutrient-poor agroecosystems under less intense fertilization. A trait-based way focusing on size distribution of nematodes is proposed to maintain environmental health by monitoring the overall diversity in soil biota, keeping agriculture and forestry sustainable. PMID- 29183363 TI - Motivation and academic performance of medical students from ethnic minorities and majority: a comparative study. AB - BACKGROUND: Medical students from ethnic minorities underperform in knowledge and skills assessments both in pre-clinical and clinical education compared to the ethnic majority group. Motivation, which influences learning and academic performance of medical students, might play an important role in explaining these differences, but is under-investigated. This study aimed to compare two types of motivation (autonomous and controlled) of ethnic minority (Western and non Western) and majority (Dutch) students, and their association with academic performance. METHODS: In a cross-sectional study, all students of a Dutch medical school were invited to complete a survey including the Academic Self-Regulation Questionnaire, measuring autonomous and controlled motivation, in the academic year 2015-2016. Motivation was compared using Kruskal-Wallis test and performance was compared using One-Way ANOVA. Linear regression analysis was used to determine the association between motivation and performance (grade point average; GPA). RESULTS: The response rate was 38.6% (n = 947). Autonomous motivation (AM) of non-Western students was higher than that of Dutch students in pre-clinical and clinical education (p < 0.05). Controlled motivation was higher in Western students than in Dutch students (pre-clinical education; p < 0.05). AM was associated with a higher GPA for Dutch (pre-clinical education; beta = 0.33, p < 0.05) and Western students (clinical education; beta = 0.57, p < 0.05) only. CONCLUSIONS: Our results show significant differences in the type of motivation between the ethnic majority and minority groups. The association of motivation with performance also differs between ethnic groups. We found that AM has a positive influence on GPA. Further research is needed to uncover the underlying mechanisms. PMID- 29183364 TI - Unusual presentations of functional parathyroid cysts: a case series and review of the literature. AB - BACKGROUND: Cysts of parathyroid origin are sometimes encountered and can easily be mistaken as thyroidal cysts. Functional parathyroid cysts, with symptoms and signs of hyperparathyroidism, are rare and may be a diagnostic challenge to clinicians. We report here on three cases of functional parathyroid cysts that illustrate diagnosis difficulties related to unusual clinical presentations in three Caucasian women, including negative parathyroid scintigraphy. CASE PRESENTATIONS: Patient 1, an 87-year-old Caucasian woman presented with confusion and dysphagia. She had hypercalcemia and elevated parathyroid hormone levels suggesting primary hyperparathyroidism. Parathyroid scintigraphy did not reveal any focal uptake, but a computed tomography scan of her neck identified a large cyst in the upper right thyroid region. At cervicotomy, a parathyroid cystic adenoma was removed. Patient 2, a 31-year-old Caucasian woman was investigated after a hypertensive crisis related to primary hyperparathyroidism. Cervical ultrasound identified a large cystic lesion in the lower left thyroid lobe that was removed by minimally invasive cervicotomy. Patient 3, a 34-year-old Caucasian woman presented with an indolent growing mass of the neck and a past medical history of kidney stones. Primary hyperparathyroidism was diagnosed. Ultrasound showed a cystic mass, but parathyroid scintigraphy was negative. Cervical exploration revealed a large cystic adenoma, containing high parathyroid hormone levels. CONCLUSIONS: Diagnosis of functional parathyroid cysts can be challenging due to various clinical presentations and negative parathyroid scintigraphy. Surgery, but not fine-needle sclerotherapy, appears to be the safest treatment option. Despite its rarity, differential diagnosis of cystic lesion of the neck should include primary hyperparathyroidism due to functional parathyroid cysts. PMID- 29183365 TI - African and classical swine fever: similarities, differences and epidemiological consequences. AB - For the global pig industry, classical (CSF) and African swine fever (ASF) outbreaks are a constantly feared threat. Except for Sardinia, ASF was eradicated in Europe in the late 1990s, which led to a research focus on CSF because this disease continued to be present. However, ASF remerged in eastern Europe in 2007 and the interest in the disease, its control and epidemiology increased tremendously. The similar names and the same susceptible species suggest a similarity of the two viral diseases, a related biological behaviour and, correspondingly, similar epidemiological features. However, there are several essential differences between both diseases, which need to be considered for the design of control or preventive measures. In the present review, we aimed to collate differences and similarities of the two diseases that impact epidemiology and thus the necessary control actions. Our objective was to discuss critically, if and to which extent the current knowledge can be transferred from one disease to the other and where new findings should lead to a critical review of measures relating to the prevention, control and surveillance of ASF and CSF. Another intention was to identify research gaps, which need to be closed to increase the chances of a successful eradication of ASF and therefore for a decrease of the economic threat for pig holdings and the international trade. PMID- 29183366 TI - The effect on the patient flow in local health care services after closing a suburban primary care emergency department: a controlled longitudinal follow-up study. AB - BACKGROUND: It has not been studied what happens to patient flow to EDs and other parts of local health care system if distances to ED services are manipulated as a part of health policy in urban areas. METHODS: The present work was an observational and quasi-experimental study with a control and it was based on before-after comparisons. The impact of terminating a geographically distant suburban primary care ED on patient flow to doctors in local public primary care EDs, office-hour primary care, secondary care EDs and in private primary care was studied. The effect of this intervention was compared with a primary care system where no similar intervention was performed. The number of monthly visits to doctors in different departments of health care was scored as the main measure of the study in each department studied (e.g. in primary care EDs, secondary care ED, office-hour public primary care and private primary care). Monthly mortality rates were also recorded. RESULTS: Increasing the distance to ED services by terminating a peripheral ED did not cause an increase in the use of local office hour services in those areas whose local ED was terminated, although use of ED services decreased by 25% in these areas (P < 0.001). The total use of primary care doctor services rather decreased - if anything - after this intervention while use of doctor services in secondary care ED remained unaffected. Doctor visits to the complementary private primary care increased but this was probably not associated with the intervention because a simultaneous increase in this parameter was observed in the control. There was no increased mortality in any age groups. CONCLUSION: Manipulating distances to ED services can be used to direct patient flows to different parts of the health care system. The correlation between distance to ED and the tendency to use ED by inhabitants is negative. If secondary care ED was available there were no life-threatening side effects at the level of general public health when a minor ED was closed in a primary care ED system. PMID- 29183367 TI - Prevalence and associated factors of hypertension among adults in Ethiopia: a community based cross-sectional study. AB - BACKGROUND: Hypertension is a growing public health problem in many developing countries including Ethiopia. It is a silent killer and most patients are detected to have it incidentally when they are admitted to hospital for unrelated disease or subjected to pre-employment or preoperative medical checkups. Information on the prevalence of hypertension and its associated factors is to be considered vital to focus and improve prevention and control of cardiovascular diseases. The study design was a cross-sectional survey. The study population consisted of adults aged 25-65 years who lived in Jigjiga city of eastern Ethiopia for at least 6 months. Data were collected using a pretested structured questionnaire, and blood pressure was measured using standardized instruments by trained clinical nurses. Hypertension was defined as having Systolic BP >= 140 mmHg or Diastolic BP >= 90 mmHg or reported use of regular anti-hypertensive medications prescribed by professionals for raised BP. Data were entered into a computer using Epi Info Version 3.5.1 and exported to SPSS version 16.0 for analysis. Multiple logistic regressions were fitted and Odds ratios with 95% confidence intervals were calculated to identify independently associated factors. RESULTS: The prevalence of hypertension was 28.3%. Family history of Hypertension [Adjusted OR 5.7; 95% CI (2.9, 10.9)], having high level of income [Adjusted OR 3.1; 95% CI (1.5, 6.3)], being male [Adjusted OR 2.4; 95% CI (1.3, 4.3)], being above grade 12 [Adjusted OR 2.2; 95% CI (1.2, 3.9)], and having BMI >= 25 [Adjusted OR 2.0; 95% CI (1.1, 3.5)] were significantly associated with hypertension. CONCLUSION: Consistent with the literatures, the prevalence of hypertension was high and may show a hidden epidemic in this population. If established with more robust and nationally representative studies, the finding calls for efficient health screening and regular checkups as well as interventions promoting healthy lifestyles. Accordingly, health promotion regarding hypertension should be provided in the population as means of primary prevention. PMID- 29183368 TI - Incidence of orthostatic hypotension and cardiovascular response to postoperative early mobilization in patients undergoing cardiothoracic and abdominal surgery. AB - BACKGROUND: In cardiothoracic and abdominal surgery, postoperative complications remain major clinical problems. Early mobilization has been widely practiced and is an important component in preventing complications, including orthostatic hypotension (OH) during postoperative management. We investigated cardiovascular response during early mobilization and the incidence of OH after cardiothoracic and abdominal surgery. METHODS: In this prospective observational study, we consecutively analyzed data from 495 patients who underwent elective cardiothoracic and abdominal surgery. We examined the incidence of OH, and the independent risk factors associated with OH during early mobilization after major surgery. Multivariate logistic regression was performed using various characteristics of patients to identify OH-related independent factors. RESULTS: OH was observed in 191 (39%) of 495 patients. The incidence of OH in cardiac, thoracic, and abdominal groups was 39 (33%) of 119, 95 (46%) of 208, and 57 (34%) of 168 patients, respectively. Male sex (OR 1.538; p = 0.03) and epidural anesthesia (OR 2.906; p < 0.001) were independently associated with OH on multivariate analysis. CONCLUSIONS: These results demonstrate that approximately 40% patients experience OH during early mobilization after cardiothoracic and abdominal surgery. Sex was identified as an independent factor for OH during early mobilization after all three types of surgeries, while epidural anesthesia was only identified after thoracic surgery. Therefore, the frequent occurrence of OH during postoperative early mobilization should be recognized.

PMID- 29183369 TI - Improving tuberculosis case detection in underdeveloped multi-ethnic regions with high disease burden: a case study of integrated control program in China. AB - BACKGROUND: In the underdeveloped multi-ethnic regions of China, high tuberculosis (TB) burden and regional inequity in access to healthcare service increase the challenge of achieving the End TB goals. Among all the provinces, the highest TB burden is reported in Xinjiang, where ethnic minorities and older people have suffered most. However, current case-finding strategy is inadequate given the complex social determinants and suboptimal case detection rates. Thus, we developed an integrated TB control program to improve case detection and conducted a pilot in Xinjiang from 2014 to 2015. In this case study, we summarized the activities and key findings. We also shared the experiences and challenges of implementing interventions and provided recommendations to inform the TB control program in the future. CASE PRESENTATION: The pilot interventions were implemented in one selected town in Yining based on local TB control programs. By applying tailor-made educational materials, outreach TB educational activities were conducted in diverse ways. In 22 Masjids, the trained imams promoted TB education to the Muslims, covering 20,440 person-times in 88 delivered preaching sessions. In seven schools, 1944 students were educated by the teachers and contributed to educating 6929 family members. In the village communities, 13,073 residents participated in household education and screening. Among them, 12,292 people aged under 65 years were investigated for suspicious pulmonary TB symptoms, where six TB patients were diagnosed out of 89 TB suspects; 781 older people were mobilized for screening directly by chest X-ray, where 10 patients were diagnosed out of 692 participants. Supportive healthcare system, multi-sectoral cooperation and multi-channel financing mechanism were the successful experiences of implementation. The interventions were proved to be more effective than the previous performance: the number of TB suspects consulting doctors and patients detected increased by 50% and 26%, respectively. The potential challenges, implications and recommendations should been taken into account for further program improvement. CONCLUSIONS: In underdeveloped multi ethnic regions with high TB burden, improving case detection is necessary and the interventions can be feasible and effective within a supportive system. More intensive educational and training approaches, a high index of TB suspicion and prioritization of older people in screening are recommended. To sustain and scale up the program, the impacts, cost-effectiveness, feasibility and acceptability of interventions warrant further research and evaluation in each specific context. PMID- 29183370 TI - Towards malaria elimination in Savannakhet, Lao PDR: mathematical modelling driven strategy design. AB - BACKGROUND: The number of Plasmodium falciparum malaria cases around the world has decreased substantially over the last 15 years, but with the spread of resistance against anti-malarial drugs and insecticides, this decline may not continue. There is an urgent need to consider alternative, accelerated strategies to eliminate malaria in countries like Lao PDR, where there are a few remaining endemic areas. A deterministic compartmental modelling tool was used to develop an integrated strategy for P. falciparum elimination in the Savannakhet province of Lao PDR. The model was designed to include key aspects of malaria transmission and integrated control measures, along with a user-friendly interface. RESULTS: Universal coverage was the foundation of the integrated strategy, which took the form of the deployment of community health workers who provided universal access to early diagnosis, treatment and long-lasting insecticidal nets. Acceleration was included as the deployment of three monthly rounds of mass drug administration targeted towards high prevalence villages, with the addition of three monthly doses of the RTS,S vaccine delivered en masse to the same high prevalence sub-population. A booster dose of vaccine was added 1 year later. The surveillance-as-intervention component of the package involved the screening and treatment of individuals entering the simulated population. CONCLUSIONS: In this modelling approach, the sequential introduction of a series of five available interventions in an integrated strategy was predicted to be sufficient to stop malaria transmission within a 3-year period. These interventions comprised universal access to early diagnosis and adequate treatment, improved access to long-lasting insecticidal nets, three monthly rounds of mass drug administration together with RTS,S vaccination followed by a booster dose of vaccine, and screening and treatment of imported cases.

AB - BACKGROUND: Breast cancer is the most common cancer which causes significant morbidity and mortality among women worldwide. Lack of medical facilities for early detection, therapeutic strategies for treatment and side effects due to pharmacological compounds have encompassed the need for new therapies mostly from natural sources. A lot of components have been identified from different snake venoms as therapeutic agents. A group of polypeptides (60-70 amino acid residues) called cytotoxins or cardiotoxins present in an elapid family of snakes have a wide variety of pharmaceutical actions and have the tendency to damage a wide variety of cells including cancerous cells. The aim of the present study was to evaluate the cytotoxic effect of NN-32 protein toxin purified from Indian Spectacled Cobra venom against human breast cancer cell lines (MCF-7 and MDA-MB 231). METHODS: The NN-32 toxin was purified by ion exchange chromatography and further by RP-HPLC. The potential anticancer effects of the NN-32 toxin on MCF-7 and MDA-MB-231 cells were evaluated using MTT, anti-proliferation, neutral red (NR) uptake and Lactate Dehydrogenase (LDH) release assay. RESULTS: The ion exchange chromatography showed various peaks among fraction no. 35 showing cytotoxic activity and this fraction showed a single peak with retention time 3.6 mins by HPLC using C18 column. The NN-32 toxin induced cytotoxicity in MCF-7 and MDA-MB-231 cells with the IC50 value of 2.5 and 6.7 MUg/ml respectively. The NN 32 showed significant cytotoxicity to both the cell lines along with low cytotoxicity to MCF-10A (normal breast epithelial) cells. The cytotoxic effect was further confirmed by the anti-proliferative, NR uptake and LDH release assays. CONCLUSION: The purified toxin NN-32 from Naja naja venom showed cytotoxic activity against MCF-7 (ER+) and MDA-MB-231(ER-) cells in both dose dependent and time dependent manner. PMID- 29183372 TI - Patient preferences for direct-to-consumer telemedicine services: a nationwide survey. AB - BACKGROUND: Direct-to-consumer (DTC) telemedicine providers has the potential to change the traditional patient-physician relationship. Professional medical organizations recommend that telemedicine exist within the medical home. This study aims to understand patients' preferences and desires for DTC telemedicine. METHODS: We conducted a nationwide survey of 4345 survey respondents demographically balanced to represent the United States adult population. The survey consisted of questions assessing the respondents' attributes and their willingness and comfortability using telemedicine as well as the importance and desired attributes of a provider providing care via telemedicine. RESULTS: Relatively few respondents (3.5%) had ever had an online video visit with their care provider. Respondents were more willing to see their own provider via telemedicine than unwilling (52% vs. 25%). Additionally, respondents were less willing to use telemedicine to see a different provider from the same healthcare organization (35%) and were least willing to see a different provider from a different organization (19%). Forty-one percent of respondents felt it was unimportant that their current provider offer telemedicine, and only 15% would consider leaving their current provider to a new provider who offers telemedicine as an option. More than half (56%) of respondents felt it was important to have an established relationship with a provider they're having a telemedicine visit with. Nearly two-thirds of respondents (60%) felt it was important for a telemedicine provider to have access to their health records. CONCLUSIONS: Patients prefer to use telemedicine with their own doctor with whom they have an established relationship. PMID- 29183373 TI - Back pain in physically inactive students compared to physical education students with a high and average level of physical activity studying in Poland. AB - BACKGROUND: The aim of the study was (1) to characterise back pain in physically inactive students as well as in trained (with a high level of physical activity) and untrained (with an average level of physical activity) physical education (PE) students and (2) to find out whether there exist differences regarding the declared incidence of back pain (within the last 12 months) between physically inactive students and PE students as well as between trained (with a high level of physical activity) and untrained (with an average level of physical activity) PE students. METHODS: The study included 1321 1st-, 2nd- and 3rd-year students (full-time bachelor degree course) of Physical Education, Physiotherapy, Pedagogy as well as Tourism and Recreation from 4 universities in Poland. A questionnaire prepared by the authors was applied as a research tool. The 10-point Visual Analogue Scale (VAS) was used to assess pain intensity. Prior to the study, the reliability of the questionnaire was assessed by conducting it on the group of 20 participants twice with a shorter interval. No significant differences between the results obtained in the two surveys were revealed (p < 0.05). RESULTS: In the group of 1311 study participants, 927 (70.7%) respondents declared having experienced back pain within the last 12 months. Physically inactive students declared back pain frequency similar to the frequency declared by their counterparts studying physical education (p > 0.05). Back pain was more common in the group of trained students than among untrained individuals (p < 0.05). Back pain was mainly located in the lumbar spine. CONCLUSIONS: A frequent occurrence of back pain (70.7%) was noted in the examined groups of students. The percentage of students declaring back pain increased in the course of studies (p < 0.05) and, according to the students' declarations, it was located mainly in the lumbar spine. No significant differences regarding the incidence of back pain were found between physically inactive students and physical education students (p > 0.05). The trained students declared back pain more often than their untrained counterparts (p < 0.05). PMID- 29183374 TI - Optimizing recombinant protein expression via automated induction profiling in microtiter plates at different temperatures. AB - BACKGROUND: Escherichia coli (E. coli) is the most abundant expression host for recombinant proteins. The production efficiency is dependent on a multitude of parameters. Therefore, high-throughput applications have become an increasingly frequent technique to investigate the main factors. Within this study, the effects of temperature, induction time and inducer concentration on the metabolic state and the product formation were extensively examined. Induction profiling of E. coli Tuner(DE3) pRhotHi-2-EcFbFP was performed in 48-well Flowerplates and standard 96-well plates using a robotic platform. In parallel shake flask cultivations, the respiration activity of the microorganisms was analyzed. Therefore, two online-monitoring systems were applied: the BioLector for microtiter plates and the RAMOS-device for shake flasks. The impact of different induction conditions on biomass and product formation as well as on the oxygen transfer rate was surveyed. RESULTS: Different optimal induction conditions were obtained for temperatures of 28, 30, 34, and 37 degrees C. The best inducer concentrations were determined to be between 0.05 and 0.1 mM IPTG for all investigated temperatures. This is 10-20 times lower than conventional guidelines suggest. The induction time was less relevant when the correct inducer concentration was chosen. Furthermore, there was a stronger impact on growth and respiration activity at higher temperatures. This indicated a higher metabolic burden. Therefore, lower IPTG concentrations were advantageous at elevated temperatures. Very similar results were obtained in standard 96-well plates. CONCLUSION: Two online-monitoring systems were successfully used to investigate the optimal induction conditions for the E. coli Tuner(DE3) pRhotHi-2-EcFbFP strain (lacY deletion mutant) at four different temperatures. The experimental effort was reduced to a minimum by integrating a liquid handling robot. To reach the maximum product formation, a detailed induction analysis was necessary. Whenever the cultivation temperature was changed, the induction conditions have to be adapted. Due to the experimental options provided by the BioLector technology, it was found that the higher the cultivation temperature, the lower the inducer concentration that has to be applied. PMID- 29183375 TI - RDL mutations predict multiple insecticide resistance in Anopheles sinensis in Guangxi, China. AB - BACKGROUND: Anopheles sinensis is a major vector of malaria in China. The gamma aminobutyric acid (GABA)-gated chloride channel, encoded by the RDL (Resistant to dieldrin) gene, is the important target for insecticides of widely varied structures. The use of various insecticides in agriculture and vector control has inevitably led to the development of insecticide resistance, which may reduce the control effectiveness. Therefore, it is important to investigate the presence and distribution frequency of the resistance related mutation(s) in An. sinensis RDL to predict resistance to both the withdrawn cyclodienes (e.g. dieldrin) and currently used insecticides, such as fipronil. METHODS: Two hundred and forty adults of An. sinensis collected from nine locations across Guangxi Zhuang Autonomous Region were used. Two fragments of An. sinensis RDL (AsRDL) gene, covering the putative insecticide resistance related sites, were sequenced respectively. The haplotypes of each individual were reconstructed by the PHASE2.1 software, and confirmed by clone sequencing. The phylogenetic tree was built using maximum-likelihood and Bayesian inference methods. Genealogical relations among different haplotypes were also analysed using Network 5.0. RESULTS: The coding region of AsRDL gene was 1674 bp long, encoding a protein of 557 amino acids. AsRDL had 98.0% amino acid identity to that from Anopheles funestus, and shared common structural features of Cys-loop ligand-gated ion channels. Three resistance-related amino acid substitutions (A296S, V327I and T345S) were detected in all the nine populations of An. sinensis in Guangxi, with the 296S mutation being the most abundant (77-100%), followed by 345S (22-47%) and 327I (8-60%). 38 AsRDL haplotypes were identified from 240 individuals at frequencies ranging from 0.2 to 34.8%. Genealogical analysis suggested multiple origins of the 345S mutation in AsRDL. CONCLUSIONS: The near fixation of the 296S mutation and the occurrence of the 327I and 345S mutations in addition to 296S, in all the nine tested An. sinensis populations in Guangxi, strongly indicate a risk of multiple insecticide resistance. The haplotype diversity plus genetic heterogeneities in the geographical distribution, and multiple origins of AsRDL alleles call for a location-customized strategy for monitoring and management of insecticide resistance. PMID- 29183376 TI - The danger of non-exhaustive quality measures: requiring hip fracture repair surgery within 48 hours - a case study. AB - Quality measures are widely used globally in order to measure clinical performance and organizational efficiency of the healthcare systems. However, in a race to achieve certain numerically defined goal, the more important purpose of any organizational step being aimed at improving clinical outcomes could be overshadowed.The introduction of the requirement to perform most hip fracture surgeries in the first 48 h of hospitalization by the Israeli Ministry of Health (IMOH) provides an interesting example of the complexity of this phenomenon. In 2004, the IMOH decided that hospitals would receive the full DRG payment for hip fractures operations only in cases in which the operation is performed within 48 h of hospitalization. In 2013, the IMOH proceeded to designate the proportion of less than 48 h surgeries as an official quality parameter for comparing hospital performance.Despite the widely acknowledged and proven clinical benefit of earlier surgery for hip fracture patients, the desired proportion of such surgeries in a given population is not easily defined for a given population, as a significant number of patients may be unsuited for immediate surgery due to medical instability, having a serious co-morbidity or receiving anticoagulant treatment. Rushing these patients to surgery can be therefore expected to have a negative effect on their outcomes, and the subsequent increase in hip fracture mortality recorded in Israel after 2013 may be a result of that.This example suggests that designating an organizational quality measure without adjusting it for the patient's medical condition may make it too inaccurate to guide healthcare policy. PMID- 29183377 TI - Impact of robust treatment planning on single- and multi-field optimized plans for proton beam therapy of unilateral head and neck target volumes. AB - BACKGROUND: Proton beam therapy is promising for the treatment of head and neck cancer (HNC), but it is sensitive to uncertainties in patient positioning and particle range. Studies have shown that the planning target volume (PTV) concept may not be sufficient to ensure robustness of the target coverage. A few planning studies have considered irradiation of unilateral HNC targets with protons, but they have only taken into account the dose on the nominal plan, without considering anatomy changes occurring during the treatment course. METHODS: Four pencil beam scanning (PBS) proton therapy plans were calculated for 8 HNC patients with unilateral target volumes: single-field (SFO) and multi-field optimized (MFO) plans, either using the PTV concept or clinical target volume (CTV)-based robust optimization. The dose was recalculated on computed tomography (CT) scans acquired during the treatment course. Doses to target volumes and organs at risk (OARs) were compared for the nominal plans, cumulative doses considering anatomical changes, and additional setup and range errors in each fraction. If required, the treatment plan was adapted, and the dose was compared with the non-adapted plan. RESULTS: All nominal plans fulfilled the clinical specifications for target coverage, but significantly higher doses on the ipsilateral parotid gland were found for both SFO approaches. MFO PTV-based plans had the lowest robustness against range and setup errors. During the treatment course, the influence of the anatomical variation on the dose has shown to be patient specific, mostly independent of the chosen planning approach. Nine plans in four patients required adaptation, which led to a significant improvement of the target coverage and a slight reduction in the OAR dose in comparison to the cumulative dose without adaptation. CONCLUSIONS: The use of robust MFO optimization is recommended for ensuring plan robustness and reduced doses in the ipsilateral parotid gland. Anatomical changes occurring during the treatment course might degrade the target coverage and increase the dose in the OARs, independent of the chosen planning approach. For some patients, a plan adaptation may be required. PMID- 29183378 TI - Vascular abnormalities and development of hypoxia in microscopic melanoma xenografts. AB - BACKGROUND: Studies investigating the oxygenation status and the development of hypoxia in microscopic tumors are sparse. The purpose of this study was to measure the extent of hypoxia in microscopic melanoma xenografts and to search for possible mechanisms leading to the development of hypoxia in these tumors. METHODS: A-07, D-12, R-18, and U-25 human melanoma xenografts grown in dorsal window chambers or as flank tumors were used as preclinical tumor models. Morphologic and functional parameters of vascular networks were assessed with intravital microscopy, and the expression of angiogenesis-related genes was assessed with quantitative PCR. Microvessels, pericytes, and the extent of hypoxia were assessed by immunohistochemistry in microscopic tumors by using CD31, alphaSMA, and pimonidazole as markers, and the extent of radiobiological hypoxia was assessed in macroscopic flank tumors. RESULTS: Macroscopic R-18 and U 25 tumors showed extensive hypoxia, whereas macroscopic A-07 and D-12 tumors were less hypoxic. R-18 and U-25 tumors developed hypoxic regions before they reached a size of 2-3 mm in diameter, whereas A-07 and D-12 tumors of similar size did not show hypoxic regions. The development of hypoxic regions was not caused by low vessel density, but was rather a result of inadequate vascular function. Inadequate vascular function was not caused by low vessel diameters or long vessel segments, but was associated with poor vascular pericyte coverage. Poor pericyte coverage was associated with the expression of eight angiogenesis related genes. CONCLUSIONS: Two of the four investigated melanoma models developed hypoxic regions in microscopic tumors, and the development of hypoxia was associated with poor vascular pericyte coverage and inadequate vascular function. PMID- 29183379 TI - Gait performance and foot pressure distribution during wearable robot-assisted gait in elderly adults. AB - BACKGROUND: A robotic exoskeleton device is an intelligent system designed to improve gait performance and quality of life for the wearer. Robotic technology has developed rapidly in recent years, and several robot-assisted gait devices were developed to enhance gait function and activities of daily living in elderly adults and patients with gait disorders. In this study, we investigated the effects of the Gait-enhancing Mechatronic System (GEMS), a new wearable robotic hip-assist device developed by Samsung Electronics Co, Ltd., Korea, on gait performance and foot pressure distribution in elderly adults. METHODS: Thirty elderly adults who had no neurological or musculoskeletal abnormalities affecting gait participated in this study. A three-dimensional (3D) motion capture system, surface electromyography and the F-Scan system were used to collect data on spatiotemporal gait parameters, muscle activity and foot pressure distribution under three conditions: free gait without robot assistance (FG), robot-assisted gait with zero torque (RAG-Z) and robot-assisted gait (RAG). RESULTS: We found increased gait speed, cadence, stride length and single support time in the RAG condition. Reduced rectus femoris and medial gastrocnemius muscle activity throughout the terminal stance phase and reduced effort of the medial gastrocnemius muscle throughout the pre-swing phase were also observed in the RAG condition. In addition, walking with the assistance of GEMS resulted in a significant increase in foot pressure distribution, specifically in maximum force and peak pressure of the total foot, medial masks, anterior masks and posterior masks. CONCLUSION: The results of the present study reveal that GEMS may present an alternative way of restoring age-related changes in gait such as gait instability with muscle weakness, reduced step force and lower foot pressure in elderly adults. In addition, GEMS improved gait performance by improving push-off power and walking speed and reducing muscle activity in the lower extremities. TRIAL REGISTRATION: NCT02843828 . PMID- 29183380 TI - Bacterial magnetosomes as an efficient gene delivery platform for cancer theranostics. AB - BACKGROUND: Gene therapy has gained an increasing interest in its anti-tumor efficiency. However, numerous efforts are required to promote them to clinics. In this study, a novel and efficient delivery platform based on bacterial magnetosomes (BMs) were developed, and the efficiency of BMs in delivering small interfering ribonucleic acid (siRNA) as well as antiproliferative effects in vitro were investigated. RESULTS: Initially, we optimized the nitrogen/phosphate ratio and the BMs/siRNA mass ratio as 20 and 1:2, respectively, to prepare the BMs-PEI-siRNA composites. Furthermore, the prepared nanoconjugates were systematically characterized. The dynamic light scattering measurements indicated that the particle size and the zeta potential of BMs-PEI-siRNA are 196.5 nm and 49.5 +/- 3.77 mV, respectively, which are optimum for cell internalization. Moreover, the confocal laser scanning microscope observations showed that these composites were at a proximity to the nucleus and led to an effective silencing effect. BMs-PEI-siRNA composites efficiently inhibited the growth of HeLa cells in a dose-as well as time-dependent manner. Eventually, a dual stain assay using acridine orange/ethidium bromide, revealed that these nanocomposites induced late apoptosis in cancer cells. CONCLUSIONS: A novel and efficient gene delivery system based on BMs was successfully produced for cancer therapy, and these innovative carriers will potentially find widespread applications in the pharmaceutical field. PMID- 29183381 TI - A promising approach to enhance microalgae productivity by exogenous supply of vitamins. AB - In order to reduce the consumption of traditional fossil fuels and their impact on the environment, strategies to mitigate greenhouse gas emissions especially carbon dioxide needs exploration. Microalgae-based biofuels can be the best-fit plant based feed-stocks for diminishing a majority of the Universe's energy problems. Interestingly, the eukaryotic microalgae aid in fixation of almost 50% of the global carbon in the environment. Thus, determination of parameters that will enhance microalgal growth and productivity is crucial, if they are to be used as future renewable energy sources. A large percentage of phytoplankton species are auxotroph for one or more vitamins. These species, in turn, are also dependent upon the vitamin biosynthetic pathways for processing of these vitamins. The present study serves as a base to discuss the prevalence of vitamin auxotrophy in microalgae and the methods of its acquirement from external sources such as heterotrophic bacteria. The next section of the paper sheds light on possible species-specific symbiotic interactions among microalgae and bacteria. Lastly is the discussion on how heterotrophic bacteria can act as a vitamin prototroph for an explicit microalgal vitamin auxotroph. The overall focus is placed upon harnessing these symbiotic interactions with intentions to obtain enhancements in microalgal biomass, lipid productivity, and flocculation rates. Moreover, the growth and distribution of a microalgal cell that thrives on a specific vitamin is perhaps met by growing it with the bacterial communities that nourish it. Thus, possibly by ecologically engineering a potential species specific microalgal-bacterial consortium, it could tremendously contribute to the acceleration of photosynthetic activity, microalgal productivity, exchange of primary metabolites and other biogeochemical nutrients within the mini ecosystem. PMID- 29183382 TI - A proposal for the withdrawal of inhaled corticosteroids in the clinical practice of chronic obstructive pulmonary disease. AB - According to the current clinical practice guidelines for chronic obstructive pulmonary disease (COPD), the addition of inhaled corticosteroids (ICS) to long acting beta2 agonist therapy is recommended in patients with moderate-to-severe disease and an increased risk of exacerbations. However, ICS are largely overprescribed in clinical practice, and most patients are unlikely to benefit from long-term ICS therapy.Evidence from recent randomized-controlled trials supports the hypothesis that ICS can be safely and effectively discontinued in patients with stable COPD and in whom ICS therapy may not be indicated, without detrimental effects on lung function, health status, or risk of exacerbations. This article summarizes the evidence supporting the discontinuation of ICS therapy, and proposes an algorithm for the implementation of ICS withdrawal in patients with COPD in clinical practice.Given the increased risk of potentially serious adverse effects and complications with ICS therapy (including pneumonia), the use of ICS should be limited to the minority of patients in whom the treatment effects outweigh the risks. PMID- 29183383 TI - The opioid epidemic: a central role for the blood brain barrier in opioid analgesia and abuse. AB - Opioids are currently the primary treatment method used to manage both acute and chronic pain. In the past two to three decades, there has been a surge in the use, abuse and misuse of opioids. The mechanism by which opioids relieve pain and induce euphoria is dependent on the drug crossing the blood-brain barrier and accessing the central nervous system. This suggests the blood brain barrier plays a central role in both the benefits and risks of opioid use. The complex physiological responses to opioids that provide the benefits and drive the abuse also needs to be considered in the resolution of the opioid epidemic. PMID- 29183384 TI - Core Health Outcomes In Childhood Epilepsy (CHOICE): protocol for the selection of a core outcome set. AB - BACKGROUND: There is increasing recognition that establishing a core set of outcomes to be evaluated and reported in trials of interventions for particular conditions will improve the usefulness of health research. There is no established core outcome set for childhood epilepsy. The aim of this work is to select a core outcome set to be used in evaluative research of interventions for children with rolandic epilepsy, as an exemplar of common childhood epilepsy syndromes. METHODS: First we will identify what outcomes should be measured; then we will decide how to measure those outcomes. We will engage relevant UK charities and health professional societies as partners, and convene advisory panels for young people with epilepsy and parents of children with epilepsy. We will identify candidate outcomes from a search for trials of interventions for childhood epilepsy, statutory guidance and consultation with our advisory panels. Families, charities and health, education and neuropsychology professionals will be invited to participate in a Delphi survey following recommended practices in the development of core outcome sets. Participants will be able to recommend additional outcome domains. Over three rounds of Delphi survey participants will rate the importance of candidate outcome domains and state the rationale for their decisions. Over the three rounds we will seek consensus across and between families and health professionals on the more important outcomes. A face-to-face meeting will be convened to ratify the core outcome set. We will then review and recommend ways to measure the shortlisted outcomes using clinical assessment and/or patient-reported outcome measures. DISCUSSION: Our methodology is a proportionate and pragmatic approach to expediently produce a core outcome set for evaluative research of interventions aiming to improve the health of children with epilepsy. A number of decisions have to be made when designing a study to develop a core outcome set including defining the scope, choosing which stakeholders to engage, most effective ways to elicit their views, especially children and a potential role for qualitative research. PMID- 29183385 TI - An investigation into aflatoxin M 1 in slaughtered fattening pigs and awareness of aflatoxins in Vietnam. AB - BACKGROUND: Aflatoxin M1 (AFM1) is a hydroxylated metabolite formed after aflatoxin B1 (AFB1) is consumed by humans and animals; it can be detected in urine, milk and blood. It is well recognized that AFB1 is toxic to humans and other animals. The International Agency for Research on Cancer (IARC) classifies aflatoxins as group 1 carcinogens and AFM1 as group 2B carcinogen. The main objective of this study was to evaluate the exposure of pigs to aflatoxins as well as to assess the public awareness of aflatoxins among people in five provinces in Vietnam. RESULTS: A total of 1920 urine samples were collected from slaughterhouses located in five provinces. Overall, the positive rate of AFM1 was 53.90% (95% confidence interval 51.64-56.15) using a cut-off of 0.15 MUg/kg (range: limit of detection to 13.66 MUg/kg, median: 0.2 MUg/kg and mean: 0.63 MUg/kg). A total of 252 people from the general population were interviewed from 5 provinces, and overall 67.86% reported being aware of aflatoxins. We also found that men and more highly educated had significantly increased awareness of aflatoxins compared to the females and primary/secondary school group. The respective odds ratios (ORs) were as follows: "male" group (OR: 2.64), "high school educated" group (OR: 3.40) and "college/university or more educated" group (OR: 10.20). CONCLUSIONS: We can conclude that pigs in Vietnam are exposed to aflatoxins to varying degrees, and there may be a risk that pork products could contain AFM1. Further investigation is needed into the possible health impacts as well as to aid in establishing regulations for animal feed to reduce the health impacts in humans and animals. PMID- 29183386 TI - Application of survival tree analysis for exploration of potential interactions between predictors of incident chronic kidney disease: a 15-year follow-up study. AB - BACKGROUND: Chronic kidney disease (CKD) is a growing public health challenges worldwide. Various studies have investigated risk factors of incident CKD; however, a very few studies examined interaction between these risk factors. In an attempt to clarify the potential interactions between risk factors of CKD, we performed survival tree analysis. METHODS: A total of 8238 participants (46.1% men) aged > 20 years without CKD at baseline [(1999-2001) and (2002-2005)], were followed until 2014. The first occurrence of CKD, defined as the estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m2, was set as the main outcome. Multivariable Cox proportional hazard (Cox PH) regression was used to identify significant independent predictors of CKD; moreover, survival tree analysis was performed to gain further insight into the potential interactions between predictors. RESULTS: The crude incidence rates of CKD were 20.2 and 35.2 per 1000 person-years in men and women, respectively. The Cox PH identified the main effect of significant predictors of CKD incidence in men and women. In addition, using a limited number of predictors, survival trees identified 12 and 10 subgroups among men and women, respectively, with different survival probability. Accordingly, a group of men with eGFR > 74 ml/min/1.73 m2, age <= 46 years, low level of physical activity, waist circumference <= 100 cm and FPG <= 4.7 mmol/l had the lowest risk of CKD incidence; while men with eGFR <= 63.4 ml/min/1.73 m2, age > 50 years had the highest risk for CKD compared to men in the lowest risk group [hazard ratio (HR), 70.68 (34.57-144.52)]. Also, a group of women aged <= 45 years and eGFR > 83.5 ml/min/1.73 m2 had the lowest risk; while women with age > 48 years and eGFR <= 69 ml/min/1.73 m2 had the highest risk compared to low risk group [HR 27.25 (19.88-37.34)]. CONCLUSION: In this post hoc analysis, we found the independent predictors of CKD using Cox PH; furthermore, by applying survival tree analysis we identified several numbers of homogeneous subgroups with different risk for incidence of CKD. Our study suggests that two methods can be used simultaneously to provide new insights for intervention programs and improve clinical decision making. PMID- 29183387 TI - Nanopore sequencing of full-length BRCA1 mRNA transcripts reveals co-occurrence of known exon skipping events. AB - BACKGROUND: Laboratory assays evaluating the effect of DNA sequence variants on BRCA1 mRNA splicing may contribute to classification by providing molecular evidence. However, our knowledge of normal and aberrant BRCA1 splicing events to date has been limited to data derived from assays targeting partial transcript sequences. This study explored the utility of nanopore sequencing to examine whole BRCA1 mRNA transcripts and to provide accurate categorisation of in-frame and out-of-frame splicing events. METHODS: The exon structure of BRCA1 transcripts from a previously studied control lymphoblastoid cell line were assessed using MinION nanopore sequencing of long-range reverse transcriptase-PCR amplicons. RESULTS: Our study identified and characterised 32 complete BRCA1 isoforms, including 18 novel isoforms which showed skipping of multiple contiguous and/or non-contiguous exons. Furthermore, we show that known BRCA1 exon skipping events, such as Delta(9,10) and Delta21, can co-occur in a single transcript, with some isoforms containing four or more alternative splice junctions. Fourteen novel isoforms were formed entirely from a combination of previously identified alternative splice junctions, suggesting that the total number of BRCA1 isoforms might be lower than the number of splicing events reported previously. CONCLUSIONS: Our results highlight complexity in BRCA1 transcript structure that has not been described previously. This finding has key implications for predicting the translation frame of splicing transcripts, important for interpreting the clinical significance of spliceogenic variants. Future research is warranted to quantitatively assess full-length BRCA1 transcript levels, and to assess the application of nanopore sequencing for routine evaluation of potential spliceogenic variants. PMID- 29183388 TI - Restraint use among selected hospitalized elderly patients in Cairo, Egypt. AB - OBJECTIVE: This study's primary objective was to investigate the prevalence of physical and chemical restraint use in selected elderly hospitalized patients. RESULTS: This study was conducted in April 2014 in four major acute care hospitals. Trained data collectors assessed the use of physical and chemical restraint among all admitted elderly patients. There were 287 elderly patients (median age 64 years, 46% women). 32 patients were restrained. The overall prevalence of restraints was 11.1%, with physical restraint use alone at 3.2% and chemical restraints use alone at 7.3%. Restraint use varied by hospital type, with the highest at the private hospital (22.9%) and the lowest at the two university hospitals (< 6%). In conclusion the prevalence of physical and chemical restraint use among admitted elderly patients in Egypt is comparable to that seen in developed countries. However, the use appears to vary widely by hospital type. The use of restraints in the elderly remains an important question considering the increasing number of elderly. PMID- 29183389 TI - Toxicological investigation of acute and chronic treatment with Gnidia stenophylla Gilg root extract on some blood parameters and histopathology of spleen, liver and kidney in mice. AB - BACKGROUND: In southeast Ethiopia, people locally use the roots of Gnidia stenophylla Gilg (Thymelaeaceae) to cure malaria and other diseases with no literature evidence substantiating its safety. The aim of this study was, therefore, to investigate the safety of the aqueous root extract of G. stenophylla after acute (single dose) and repeated sub chronic oral administration in mice. RESULTS: A single oral administration of the extract at 500, 1000, 2000 and 4000 mg/kg body weight did not induce any behavioral change and mortality in both sexes. The oral LD50 of the extract was found to be above 6000 mg/kg body weight in mice. Chronic treatment with the extract for 13 weeks did not induce any sign of illness and/or death and had no adverse effect on the body weight. Dose-related elevations of erythrocytes, hematocrit, hemoglobin, platelets and neutrophils differential and significant decrease in the number of lymphocyte were observed. Liver sections of mice treated with 800 mg/kg body weight, revealed mild inflammations around the portal triads and central veins; whereas the spleen and kidneys appeared normal with no detectable gross morphological and histopathological alteration at both doses. CONCLUSIONS: The results of this study revealed that aqueous root extract of G. stenophylla Gilg at antimalarial dose is safe even when taken for a longer period. At a higher dose, the extract may have a potential to increase some hematological indices but may induce mild hepatotoxicity as a side effect.

AB - BACKGROUND: Controversies exist as to whether the genetic polymorphisms of the enzymes responsible for the metabolism of tamoxifen can predict breast cancer outcome in patients using adjuvant tamoxifen. Direct measurement of concentrations of active tamoxifen metabolites in serum may be a more biological plausible and robust approach. We have investigated the association between CYP2D6 genotypes, serum concentrations of active tamoxifen metabolites, and long term outcome in tamoxifen treated breast cancer patients. METHODS: From an original observational study comprising 817 breast cancer patients, 99 women with operable breast cancer were retrospectively included in the present study. This cohort of patients were adjuvantly treated with tamoxifen, had provided serum samples suitable for measuring tamoxifen metabolites, and were relapse-free at 3 years after the primary treatment commenced. The median follow-up time from this entry point to breast cancer death was 13.9 years. Patients were CYP2D6 genotyped and grouped into four CYP2D6 phenotype groups (Ultra rapid, extensive, intermediate, and poor metabolizers). Tamoxifen and nine metabolites were quantified in serum (n = 86) and compared with CYP2D6 phenotype groups and outcome. RESULTS: Breast cancer patients with low concentrations of Z-4-hydroxy tamoxifen (Z-4OHtam; <= 3.26 nM) had a breast cancer-specific survival (BCSS) of 60% compared to 84% in patients with Z-4OHtam concentrations > 3.26 nM (p = 0.020, log-rank hazard ratio (HR) = 3.56, 95% confidence interval (CI) = 1.14 11.07). For patients with Z-4-hydroxy-N-desmethyl-tamoxifen (Z-endoxifen) levels <= 9.00 nM BCSS was 57% compared to 84% for patients with concentrations > 9.00 nM (p = 0.029, HR = 3.73, 95% CI = 1.05-13.22). Low concentrations of Z-4OHtam and Z-endoxifen were associated with poorer survival also after adjusting for clinically relevant variables (HR = 4.27, 95% CI = 1.35-13.58, and HR = 3.70, 95% CI = 1.03-13.25, respectively). Overall survival analysis showed similar survival differences for both active metabolites. The Antiestrogen Activity Score showed comparable effects, but did not improve the prognostic information. CONCLUSIONS: Patients with Z-4OHtam and Z-endoxifen concentrations lower than 3.26 nM or 9.00 nM, respectively, showed an adverse outcome. Our results suggest that direct measurement of active tamoxifen metabolite concentrations could be of clinical value. Validation in larger study cohorts is warranted. PMID- 29183392 TI - Host-specific Dactylogyrus parasites revealing new insights on the historical biogeography of Northwest African and Iberian cyprinid fish. AB - BACKGROUND: Host specificity in parasites represents the extent to which a parasite's distribution is limited to certain host species. Considering host specific parasites of primarily freshwater fish (such as gill monogeneans), their biogeographical distribution is essentially influenced by both evolutionary and ecological processes. Due to the limited capacity for historical dispersion in freshwater fish, their specific coevolving parasites may, through historical host parasite associations, at least partially reveal the historical biogeographical routes (or historical contacts) of host species. We used Dactylogyrus spp., parasites specific to cyprinid fish, to infer potential historical contacts between Northwest African and European and Asian cyprinid faunas. Using phylogenetic reconstruction, we investigated the origin(s) of host-specific Dactylogyrus spp. parasitizing Northwest African and Iberian cyprinid species. RESULTS: In accordance with hypotheses on the historical biogeography of two cyprinid lineages in Northwest Africa, Barbini (Luciobarbus) and Torini (Carasobarbus), we demonstrated the multiple origins of Northwest African Dactylogyrus. Dactylogyrus spp. of Carasobarbus spp. originated from Asian cyprinids, while Dactylogyrus spp. of Luciobarbus spp. originated from European cyprinids. This indicates the historical Northern route of Dactylogyrus spp. dispersion to Northwest African Luciobarbus species rather than the Southern route, which is currently widely accepted for Luciobarbus. In addition, both Northwest African cyprinid lineages were also colonized by Dactylogyrus marocanus closely related to Dactylogyrus spp. parasitizing African Labeo spp., which suggests a single host switch from African Labeonini to Northwest African Luciobarbus. We also demonstrated the multiple origins of Dactylogyrus spp. parasitizing Iberian Luciobarbus species. One Iberian Dactylogyrus group was phylogenetically closely related to Dactylogyrus of Moroccan Carasobarbus, while the second was related to Dactylogyrus of Moroccan Luciobarbus. CONCLUSIONS: Our study confirms the different origins of two Northwest African cyprinid lineages. It suggests several independent historical contacts between European Iberian Luciobarbus and two lineages of Northwest African cyprinids, these contacts associated with host switches of Dactylogyrus parasites. PMID- 29183391 TI - Oxidative stress and cellular pathologies in Parkinson's disease. AB - Parkinson's disease (PD) is a chronic and progressive neurodegeneration of dopamine neurons in the substantia nigra. The reason for the death of these neurons is unclear; however, studies have demonstrated the potential involvement of mitochondria, endoplasmic reticulum, alpha-synuclein or dopamine levels in contributing to cellular oxidative stress as well as PD symptoms. Even though those papers had separately described the individual roles of each element leading to neurodegeneration, recent publications suggest that neurodegeneration is the product of various cellular interactions. This review discusses the role of oxidative stress in mediating separate pathological events that together, ultimately result in cell death in PD. Understanding the multi-faceted relationships between these events, with oxidative stress as a common denominator underlying these processes, is needed for developing better therapeutic strategies. PMID- 29183394 TI - Socio-demographic factors and availability of piped fountains affect food hygiene practice of food handlers in Bahir Dar Town, northwest Ethiopia: a cross sectional study. AB - BACKGROUND: Morbidity and mortality rates of food borne diseases are consistently highest in African due to poor food handling and sanitation practices. Thus, the study aimed to assess food handling practice and associated factors among food handlers of Restaurants in Bahir Dar Town, northwest, Ethiopia. A cross-sectional study was conducted from December, 7/2012 to January, 2/2013 among food handlers working in 106 restaurants in Bahir Dar Town. A structured questionnaire composed of socio-demographic factors, food safety knowledge, working environmental characteristics and food hygiene practice of food handlers was employed to collect the data via interviewing and observations. Binary logistic regression model was fitted to assess factors associated with food hygiene practice after multi-collinearity and outlier were checked and data was clean. Both crude odds ratio (COR) and adjusted odds ratio (AOR) were estimated to show the strength of association. In multivariate analysis, variables with a P value of <= 0.05 were considered as statistical significant. RESULTS: About 67.6% [95% confidence interval (CI) 58.8, 76.4] of food handlers had good food hygiene practice, whereas 32.4% of food handlers had poor food hygiene practice. The odds of having good food hygiene practice was higher among food handlers who had received food safety training [AOR: 4.7, 95% CI 1.7, 12.8], had formal education [AOR: 6.4, 95% CI 3.5, 11.5] and work experiences greater than 2 years [AOR: 3.4, 95% CI 1.8, 6.4]. At last, food handlers working in restaurants which had piped fountains for hand wash were 2.1 times more likely to have good food hygiene practice[AOR: 2.1, 95% CI 1.1, 3.8]. CONCLUSION: In this study, the overall food hygiene practice of food handlers is not to the acceptable level. Therefore, endeavors ought to be reinforced to improve food hygiene practices of food handlers through intervention programs such as training and education. Also emphasis should be given on the accessibility of piped fountains for the better food handling practice of food handlers. PMID- 29183393 TI - Prophylactic penehyclidine inhalation for prevention of postoperative pulmonary complications in high-risk patients: study protocol of a randomized controlled trial. AB - BACKGROUND: Postoperative pulmonary complications (PPCs) are major causes of morbidity, mortality, and prolonged hospital stay in patients after surgery. Using effective strategies to prevent its occurrence is essential to improve outcome. However, despite various efforts, the incidence of PPCs remains elevated in high-risk patients. Anticholinergic inhalation is used to reduce high airway resistance and improve pulmonary function; it may be helpful to decrease the risk of PPCs. Penehyclidine is a long-acting anticholinergic agent which selectively blocks M1 and M3 receptors. We hypothesize that, in high-risk patients, prophylactic penehyclidine inhalation may decrease the incidence of PPCs. METHODS: This is a randomized, double-blind, placebo-controlled trial with two parallel arms. A total of 864 patients at high risk of PPCs will be enrolled and randomized to receive prophylactic inhalation of either penehyclidine or placebo (water for injection). Study drug inhalation will be administered from the night (7 pm) before surgery until the second day after surgery, in an interval of every 12 hours. The primary outcome is the incidence of PPCs within 30 days after surgery. Secondary outcomes include the time to onset of PPCs (from end of surgery to first diagnosis of PPCs), the number of PPCs (indicates the number of diagnosed individual PPCs), the incidence of postoperative extrapulmonary complications, the length of stay in hospital after surgery, and the 30-day all cause mortality. DISCUSSION: Results of the present study will provide evidence to guide clinical practice in using prophylactic inhalation of an anticholinergic to prevent PPCs in high-risk patients. TRIAL REGISTRATION: The study was registered prospectively in Chinese Clinical Trial Registry ( www.chictr.org.cn , ChiCTR-IPC-15006603 ) on 14 May 2015 and retrospectively in ClinicalTrials.gov ( NCT02644876 ) on 30 December 2015. PMID- 29183395 TI - Serotyping and antibiotic susceptibility patterns of Vibrio and Shigella isolates from diarrheal patients visiting a Tropical and Infectious Diseases Hospital in central Nepal. AB - BACKGROUND: Diarrheal diseases are the major infectious disease in developing countries like Nepal. Lack of proper sanitation and antimicrobial resistance gained by microbes have challenged to address diarrheal diseases in resource limited countries. Early diagnosis of disease and proper antibiotic treatment can significantly reduce the disease burden. This study was designed to determine the recent antimicrobial susceptibility pattern of Vibrio cholerae and Shigella spp. to assure the proper antibiotic treatment. Stool specimens were processed following microbiological protocol and identified by biochemical and serological tests recommended by the Clinical Laboratory Standard Institute. RESULTS: Out of total 640 analyzed stool samples, 50 were culture positive, among them 29 were Shigella spp. (64.4%) and 21 were V. cholerae (46.6%). All V. cholerae strains belonged to the serogroup O1 and serovar Ogawa. Among the Shigella spp., Shigella flexneri 17 (59%) topped the list of serotype followed by Shigella sonnei 8 (28%), Shigella dysenteriae 3 (10%) and Shigella boydii 1 (3%) respectively. All the V. cholerae isolates (100%) were sensitive to cefotaxime while 71% were sensitive to tetracycline but 100 and 90.4% were resistance to co-trimoxazole and nalidixic acid respectively. Shigella isolates were mostly susceptible to cefotaxime (97%) while ciprofloxacin (48%) and ofloxacin (55%) were less effective drugs. CONCLUSIONS: These results on the prevalence of enteropathogens and their antibiotic resistance pattern may help to guide accurate choice of therapy in clinical setting. Hence, development of evidence based National Guidelines for the treatment of diarrhea is needed. PMID- 29183396 TI - Indirect estimation of the prevalence of spinal muscular atrophy Type I, II, and III in the United States. AB - BACKGROUND: Spinal muscular atrophy (SMA) is a progressive, devastating disease and a leading inherited cause of infant mortality. The limited population-based literature is confined to small regional studies. Estimates of prevalence are needed to characterize the burden of SMA and to understand trends in prevalence by disease type as new treatments become available. The reported estimates of SMA genotype prevalence at birth consistently range from 8.5-10.3 per 100,000 live births, with a mid-range estimate of 9.4 per 100,000. Among infants born with an SMA genotype, it is reported that ~58% will develop SMA Type I, 29% will develop Type II, and 13% will develop Type III, respectively. RESULTS: Using evidence from peer-reviewed literature for SMA birth prevalence, age at symptom onset, and SMA type-specific survival, and incorporating United States vital statistics, we constructed life tables to estimate prevalence for SMA Types I, II, and III in the United States. We estimated the number of prevalent cases in the US to be 8526, 9429, and 10,333 based on a birth prevalence of 8.5, 9.4, and 10.3, respectively (the lower, midpoint, and upper ends of the reported range). Assuming the midpoint of 9.4 and US-reported survival, the type-specific population prevalence estimates were 1610 for SMA Type I, 3944 for SMA Type II, and 3875 for SMA Type III. Evidence-based estimates of the number of people living with SMA in the United States in the published literature were previously unavailable. CONCLUSIONS: In the absence of a survey or other means to directly estimate prevalence in the US population, estimates can be calculated indirectly using a life table. PMID- 29183397 TI - Schistosomiasis, intestinal helminthiasis and nutritional status among preschool aged children in sub-urban communities of Abeokuta, Southwest, Nigeria. AB - OBJECTIVE: Schistosomiasis and intestinal helminthiasis are major public health problems with school-aged children considered the most at-risk group. Pre-school aged children (PSAC) are excluded from existing control programs because of limited evidence of infections burden among the group. We assessed the prevalence of infections and effect on nutritional status of preschool aged children in Abeokuta, Southwestern Nigeria. RESULTS: A community-based cross-sectional study involving 241 children aged 0-71 months was conducted in 4 sub-urban communities of Abeokuta. Urine and faecal samples were collected for laboratory diagnosis for parasites ova. Nutritional status determined using age and anthropometric parameters was computed based on World Health Organization 2006 growth standards. Data were subjected to descriptive statistics analysis, Chi square, t-test and ANOVA. Of 167 children with complete data, 8 (4.8%) were infected with Schistosoma haematobium; Schistosoma mansoni 6 (3.6%); Taenia species 84 (50.3%); Ascaris lumbricoides 81 (48.5%) and hookworm 63 (37.7%). Overall, 46.7% of the children were malnourished, 39.5% stunted, 22.8% underweight and 11.4% exhibiting wasting/thinness. Mean values of anthropometric indices were generally lower in children with co-infection than those with single infection. We observed low level of schistosomiasis but high prevalence of intestinal helminthiasis and poor nutritional status that calls for inclusion of PSAC in control programs. PMID- 29183398 TI - An ethnographic observation study of the facilitator role in an implementation process. AB - BACKGROUND: Even though the importance of a facilitator during an implementation process is well described, the facilitator's role is rarely problematized in relation to the organizational context in terms of power and legitimacy; themes which have recently been brought to the fore when studying change in health care organizations. Therefore, in this article, we present a qualitative study with the aim of identifying key aspects of the experience of being in a facilitator role. The data collection involved ethnographic fieldwork encompassing observations and field notes, as well as two qualitative interviews with the facilitator. The data were analysed using a phenomenological hermeneutical method in order to formulate thematic aspects of the implementation process. The study was conducted in southern Sweden between January 2013 and August 2014. RESULTS: One main theme, "walking a tightrope", and four sub-themes, all of which involved balancing acts of different levels and different ways, were identified. These included: being in control, but needing to adjust; pushing for change, but forced to stand back; being accepted, but dependent; and being reasonable, but culturally sensitive. CONCLUSION: Instead of listing the desirable qualities and conditions of a facilitator, this study shows that being a facilitator can be described more completely by applying the concept of role, thus allowing a more holistic process of reflection and analysis. This in turn makes it possible to move from the reactive stance of balancing to a more proactive stance of negotiating. PMID- 29183399 TI - Evaluating progestogens for prevention of preterm birth international collaborative (EPPPIC) individual participant data (IPD) meta-analysis: protocol. AB - BACKGROUND: Preterm birth is the most common cause of death and harm to newborn babies. Babies that are born early may have difficulties at birth and experience health problems during early childhood. Despite extensive study, there is still uncertainty about the effectiveness of progestogen (medications that are similar to the natural hormone progesterone) in preventing or delaying preterm birth, and in improving birth outcomes. The Evaluating Progestogen for Prevention of Preterm birth International Collaborative (EPPPIC) project aims to reduce uncertainty about the specific conditions in which progestogen may (or may not) be effective in preventing or delaying preterm birth and improving birth outcomes. METHODS: The design of the study involves international collaborative individual participant data meta-analysis comprising systematic review, re-analysis, and synthesis of trial datasets. Inclusion criteria are as follows: randomized controlled trials comparing progestogen versus placebo or non-intervention, or comparing different types of progestogen, in asymptomatic women at risk of preterm birth. Main outcomes are as follows; fetal/infant death, preterm birth or fetal death (<=37 weeks, <=34 weeks, <= 28 weeks), serious neonatal complications or fetal/infant death, neurosensory disability (measured at 18 months or later) or infant/child death, important maternal morbidity, or maternal death. In statistical methods, IPD will be synthesized across trials using meta-analysis. Both 'two-stage' models (where effect estimates are calculated for each trial and subsequently pooled in a meta-analysis) and 'one-stage' models (where all IPD from all trials are analyzed in one step, while accounting for the clustering of participants within trials) will be used. If sufficient suitable data are available, a network meta-analysis will compare all types of progesterone and routes of administration extending the one-stage models to include multiple treatment arms. DISCUSSION: EPPPIC is an international collaborative project being conducted by the forming EPPPIC group, which includes trial investigators, an international secretariat, and the research project team. Results, which are intended to contribute to improvements in maternal and child health, are expected to be publicly available in mid 2018. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42017068299. PMID- 29183400 TI - Predicting cancer type from tumour DNA signatures. AB - BACKGROUND: Establishing the cancer type and site of origin is important in determining the most appropriate course of treatment for cancer patients. Patients with cancer of unknown primary, where the site of origin cannot be established from an examination of the metastatic cancer cells, typically have poor survival. Here, we evaluate the potential and limitations of utilising gene alteration data from tumour DNA to identify cancer types. METHODS: Using sequenced tumour DNA downloaded via the cBioPortal for Cancer Genomics, we collected the presence or absence of calls for gene alterations for 6640 tumour samples spanning 28 cancer types, as predictive features. We employed three machine-learning techniques, namely linear support vector machines with recursive feature selection, L 1-regularised logistic regression and random forest, to select a small subset of gene alterations that are most informative for cancer type prediction. We then evaluated the predictive performance of the models in a comparative manner. RESULTS: We found the linear support vector machine to be the most predictive model of cancer type from gene alterations. Using only 100 somatic point-mutated genes for prediction, we achieved an overall accuracy of 49.4+/-0.4 % (95 % confidence interval). We observed a marked increase in the accuracy when copy number alterations are included as predictors. With a combination of somatic point mutations and copy number alterations, a mere 50 genes are enough to yield an overall accuracy of 77.7+/-0.3 %. CONCLUSIONS: A general cancer diagnostic tool that utilises either only somatic point mutations or only copy number alterations is not sufficient for distinguishing a broad range of cancer types. The combination of both gene alteration types can dramatically improve the performance. PMID- 29183401 TI - Primary replication and invasion of the bovine gammaherpesvirus BoHV-4 in the genital mucosae. AB - Bovine herpesvirus 4 (BoHV-4) is a gammaherpesvirus that is widespread in cattle. Ex vivo models with bovine genital tract mucosa explants were set up to study molecular/cellular BoHV-4-host interactions. Bovine posterior vagina, cervix and uterus body were collected from cows at two stages of the reproductive cycle for making mucosa explants. The BoHV-4 replication kinetics and characteristics within the three different mucosae of animals in the follicular and luteal phase were assessed by virus titration. The number of plaques, plaque latitude and number of infected cells were determined by immunofluorescence. BoHV-4 replicated in a productive way in all genital mucosal tissues. It infected single individual cells in both epithelium and lamina propria of the genital mucosae at 24 hours post-inoculation (hpi). Later, small BoHV-4 epithelial plaques were formed that did not spread through the basement membrane. 50% of the number of BoHV-4 infected cells were identified as cytokeratin+ and CD172a+ cells in the three parts of the genital tract at 24 hpi. Upon a direct injection of genital explants with BoHV-4, fibrocytes became infected, indicating that the unidentified 50% of the infected cells are most probably fibrocytes. In this study, in vivo-related in vitro genital tract models were successfully established and the early stage of the pathogenesis of a genital infection was clarified: BoHV-4 starts with a productive infection of epithelial cells in the reproductive tract, forming small foci followed by a non-productive infection of surveilling monocytic cells which help BoHV-4 to invade into deeper tissues. PMID- 29183404 TI - Prolonged prostaglandin-E2-associated periosteal reaction and elevated C-reactive protein levels. AB - This is a case review of two infants who received a prolonged course of prostaglandin-E2 therapy for congenital cardiac lesions while awaiting corrective surgery. These cases highlight an association between prolonged prostaglandin-E2 therapy with periosteal reactions and elevated C-reactive protein levels. Failure to recognise this association may lead to multiple courses of antibiotics for presumed sepsis and further prolongation of prostaglandin-E2 therapy. PMID- 29183402 TI - Two sides of the same coin? Unraveling subtle differences between human embryonic and induced pluripotent stem cells by Raman spectroscopy. AB - BACKGROUND: Human pluripotent stem cells, including embryonic stem cells and induced pluripotent stem cells, hold enormous promise for many biomedical applications, such as regenerative medicine, drug testing, and disease modeling. Although induced pluripotent stem cells resemble embryonic stem cells both morphologically and functionally, the extent to which these cell lines are truly equivalent, from a molecular point of view, remains controversial. METHODS: Principal component analysis and K-means cluster analysis of collected Raman spectroscopy data were used for a comparative study of the biochemical fingerprint of human induced pluripotent stem cells and human embryonic stem cells. The Raman spectra analysis results were further validated by conventional biological assays. RESULTS: Raman spectra analysis revealed that the major difference between human embryonic stem cells and induced pluripotent stem cells is due to the nucleic acid content, as shown by the strong positive peaks at 785, 1098, 1334, 1371, 1484, and 1575 cm-1, which is enriched in human induced pluripotent stem cells. CONCLUSIONS: Here, we report a nonbiological approach to discriminate human induced pluripotent stem cells from their native embryonic stem cell counterparts. PMID- 29183405 TI - Socio-economic factors associated with an increase in fruit and vegetable consumption: a 12-year study in women from the E3N-EPIC study. AB - OBJECTIVE: To identify individual and contextual socio-economic factors associated with an increase in fruit and vegetable (F&V) consumption over a 12 year period and evaluate if some socio-economic factors were differentially associated with the change in consumption of some types of F&V. DESIGN: Associations between increased F&V consumption and socio-economic factors were studied with multivariate logistic regression. SETTING: E3N, a French prospective cohort study of 98 995 women. SUBJECTS: E3N participants (n 58 193) with information on diet in 1993 and 2005, and numerous individual and contextual socio-economic factors available. RESULTS: Associations between some individual socio-economic factors and changes in F&V consumption were observed. For instance, women who lived in a large household (>3 children v. no child) had higher probability of increasing their vegetable consumption (OR=1.33; 95 % CI 1.24, 1.42). This association was driven by higher consumption of courgette and raw cucumber. Living with a partner was associated with higher odds of increasing consumption of fruits (OR=1.07; 95 % CI 1.02, 1.13) such as pear, peach and grape. CONCLUSIONS: Certain individual socio-economic factors, but none of the contextual socio-economic factors examined, were associated with an increase in F&V consumption. Factors associated with an increase in total F&V consumption were not necessarily associated with an increase in fruit or vegetable consumption separately, or with an increase in each subtype of fruit or vegetable. Magnitudes of the different associations observed also differed when F&V were considered together, separately or by subtype. Increases in F&V consumption were mostly observed in women with high socio-economic position. To develop effective nutritional interventions and policies that take the socio economic environment of individuals into account, we recommend future research to further focus on (i) pathways through which population characteristics might influence changes in F&V consumption and (ii) existing interactions between individual and contextual socio-economic factors. PMID- 29183406 TI - Coping Strategies in Mothers of Children with Intellectual Disabilities Showing Multiple Forms of Challenging Behaviour: Associations with Maternal Mental Health. AB - BACKGROUND: It is well documented that mothers of children with intellectual disabilities experience elevated mental health difficulties and that these are exacerbated by the presence of challenging behaviour. However, comparatively little is known about the effect of specific coping strategies for managing such behaviours. AIMS: This paper aims to document coping strategies used by mothers of children showing multiple forms of challenging behaviour and to explore how these relate to positive and negative maternal mental health. METHOD: Eighty-nine mothers of children with intellectual disabilities completed questionnaires assessing maternal mental health (Hospital Anxiety and Depression Scale, Positive and Negative Affect Scale) and maternal coping strategies (Brief COPE). RESULTS: Coping strategies were not associated with child age or ability, but were associated with maternal mental health. Higher levels of problem- and positive coping strategies were associated with higher positive affect. Although active avoidance coping was the least frequently reported, it was associated with higher levels of negative affect and increased anxiety and depression. Moderated mediation analyses identified that active-avoidance coping mediated the relationship between the number of forms of challenging behaviour and poor maternal mental health, but only in mothers with lower levels of problem-focused coping. CONCLUSIONS: Active-avoidance coping is associated with poorer negative mental health in mothers of children with intellectual disabilities who have average to low levels of problem-focused coping. This is reflective of that noted within a range of populations, highlighting it as a key area for intervention. PMID- 29183407 TI - Phage-mediated dissemination of virulence factors in pathogenic bacteria facilitated by antibiotic growth promoters in animals: a perspective. AB - Addition of sub-therapeutic antibiotics to the feed of food-producing animals for growth promotion and disease prevention has become a common agricultural practice in many countries. The emergence of antibiotic-resistant pathogens is a looming concern associated with the use of antibiotic growth promoters (AGPs) around the world. In addition, some studies have shown that AGPs may not only affect antibiotic resistance but may also stimulate the dissemination of virulence factors via bacteriophages. Although only a few studies are currently available in the literature regarding this topic, in this article we endeavor to provide a perspective about how AGPs would impact the transmission of virulence factors by horizontal gene transfer via phages in a few pathogenic bacterial species significant to livestock production. PMID- 29183403 TI - Linkage, whole genome sequence, and biological data implicate variants in RAB10 in Alzheimer's disease resilience. AB - BACKGROUND: While age and the APOE epsilon4 allele are major risk factors for Alzheimer's disease (AD), a small percentage of individuals with these risk factors exhibit AD resilience by living well beyond 75 years of age without any clinical symptoms of cognitive decline. METHODS: We used over 200 "AD resilient" individuals and an innovative, pedigree-based approach to identify genetic variants that segregate with AD resilience. First, we performed linkage analyses in pedigrees with resilient individuals and a statistical excess of AD deaths. Second, we used whole genome sequences to identify candidate SNPs in significant linkage regions. Third, we replicated SNPs from the linkage peaks that reduced risk for AD in an independent dataset and in a gene-based test. Finally, we experimentally characterized replicated SNPs. RESULTS: Rs142787485 in RAB10 confers significant protection against AD (p value = 0.0184, odds ratio = 0.5853). Moreover, we replicated this association in an independent series of unrelated individuals (p value = 0.028, odds ratio = 0.69) and used a gene-based test to confirm a role for RAB10 variants in modifying AD risk (p value = 0.002). Experimentally, we demonstrated that knockdown of RAB10 resulted in a significant decrease in Abeta42 (p value = 0.0003) and in the Abeta42/Abeta40 ratio (p value = 0.0001) in neuroblastoma cells. We also found that RAB10 expression is significantly elevated in human AD brains (p value = 0.04). CONCLUSIONS: Our results suggest that RAB10 could be a promising therapeutic target for AD prevention. In addition, our gene discovery approach can be expanded and adapted to other phenotypes, thus serving as a model for future efforts to identify rare variants for AD and other complex human diseases. PMID- 29183408 TI - Prevalence and temporal trend (2005-2015) of anaemia among children in Northeast Brazil. AB - OBJECTIVE: Anaemia is the main nutritional deficiency in Brazil, and a prevention and control programme (National Program for Iron Supplementation) has been developed since 2005. Studies on the temporal evolution of anaemia prevalence contribute to assessment of the effectiveness of the actions undertaken. The present study aimed to identify the prevalence and temporal trend of anaemia in children. DESIGN: Study based on two cross-sectional household surveys carried out in 2005 and 2015. Anaemia was defined as Hb<11 g/dl (HemoCue(r)). Trend analysis was performed using the prevalence ratio (PR), calculated by Poisson regression with a robust adjustment of the variance. Differences were significant when P<0.05 in both crude analyses and those adjusted for possible confounding factors (e.g. socio-economic, demographic and health variables). SETTING: Alagoas, Brazil. SUBJECTS: In total, 666 and 782 children in the first and second Alagoas State Health and Nutrition Survey, respectively (probabilistic samples). RESULTS: In 2005 and 2015, anaemia prevalence was 45.1 and 27.4 %, respectively ( 39.1 %; PR=0.61; 95 % CI 0.52, 0.70). In both surveys, children aged <=24 months were more affected (P24 months (67.2 v. 40.7 %; 27.0 v. 19.3 %, respectively). CONCLUSIONS: The prevalence of anaemia reduced significantly in the evaluated period. Thus, it may no longer be a severe public health problem but can instead be considered a problem of moderate magnitude. It remains, however, above the level considered acceptable according to WHO criteria. These results justify the implementation of prevention and control actions. PMID- 29183409 TI - Genetic risk of major depressive disorder: the moderating and mediating effects of neuroticism and psychological resilience on clinical and self-reported depression. AB - BACKGROUND: Polygenic risk scores (PRS) for depression correlate with depression status and chronicity, and provide causal anchors to identify depressive mechanisms. Neuroticism is phenotypically and genetically positively associated with depression, whereas psychological resilience demonstrates negative phenotypic associations. Whether increased neuroticism and reduced resilience are downstream mediators of genetic risk for depression, and whether they contribute independently to risk remains unknown. METHODS: Moderating and mediating relationships between depression PRS, neuroticism, resilience and both clinical and self-reported depression were examined in a large, population-based cohort, Generation Scotland: Scottish Family Health Study (N = 4166), using linear regression and structural equation modelling. Neuroticism and resilience were measured by the Eysenck Personality Scale Short Form Revised and the Brief Resilience Scale, respectively. RESULTS: PRS for depression was associated with increased likelihood of self-reported and clinical depression. No interaction was found between PRS and neuroticism, or between PRS and resilience. Neuroticism was associated with increased likelihood of self-reported and clinical depression, whereas resilience was associated with reduced risk. Structural equation modelling suggested the association between PRS and self-reported and clinical depression was mediated by neuroticism (43-57%), while resilience mediated the association in the opposite direction (37-40%). For both self-reported and clinical diagnoses, the genetic risk for depression was independently mediated by neuroticism and resilience. CONCLUSIONS: Findings suggest polygenic risk for depression increases vulnerability for self-reported and clinical depression through independent effects on increased neuroticism and reduced psychological resilience. In addition, two partially independent mechanisms - neuroticism and resilience - may form part of the pathway of vulnerability to depression.

AB - Invasive parasites can spill over to new hosts in invaded ecosystems with often unpredictable trophic relationships in the newly arising parasite-host interactions. In European seas, the intestinal copepod Mytilicola orientalis was co-introduced with Pacific oysters (Magallana gigas) and spilled over to native blue mussels (Mytilus edulis), with negative impacts on the condition of infected mussels. However, whether the parasite feeds on host tissue and/or stomach contents is yet unknown. To answer this question, we performed a stable isotope analysis in which we included mussel host tissue and the primary food sources of the mussels, microphytobenthos (MPB) and particulate organic matter (POM). The copepods were slightly enriched in delta15N (mean Delta15N +/- s.d.; 1.22 +/- 0.580/00) and delta13C (Delta13C 0.25 +/- 0.320/00) with respect to their host. Stable isotope mixing models using a range of trophic fractionation factors indicated that host tissue was the main food resource with consistent additional contributions of MPB and POM. These results suggest that the trophic relationship of the invasive copepod with its mussel host is parasitic as well as commensalistic. Stable isotope studies such as this one may be a useful tool to unravel trophic relationships in new parasite-host associations in the course of invasions. PMID- 29183411 TI - An ARV1 homologue from a filarial nematode is functional in yeast. AB - The transmembrane protein, ARV1, plays a key role in intracellular sterol homeostasis by controlling sterol distribution and cellular uptake. To date, only the ARV1s from yeast and humans have been characterized to some extent. In this study, the ARV1 of an animal filarial parasite, Setaria digitata (SdARV1), was characterized; its cDNA was 761 bp and encoded a protein of 217 amino acids, with a predicted molecular weight of 25 kDa, containing a highly conserved ARV1 homology domain and three transmembrane domains in the bioinformatic analyses. Information required to cluster members belonging to a particular taxon has been revealed in phylogenetic analyses of ARV1 sequences derived from different organisms. Reverse transcription-polymerase chain reaction (RT-PCR) analyses indicated that SdARV1 was expressed in different developmental stages - microfilariae and adult male and female worms. Experiments carried out with a single copy of the SdARV1 under the control of the PMA-1 promoter in a temperature-sensitive Saccharomyces cerevisiae mutant strain indicated full complementation of the mutant phenotype, with growth at a non-permissive temperature (37 degrees C). Microscopic observations of cellular morphology with Gram staining revealed alteration of the shape from shrunken to oval, in mutant and complemented strains, respectively. Assessment of free sterol levels extracted from mutant yeast and complemented strains indicated that the level of sterol was significantly higher in the former compared to the latter, which had sterol levels similar to those of the wild type. Thus, the results of the current study suggest that SdARV1 is ubiquitously expressed in different developmental stages of S. digitata, and that it is a true functional homologue of mammalian and yeast ARV1s, which have crucial phylogenetic information that follows classical evolutionary trends. Finally, this is the first study to report the biological function of nematode ARV1. PMID- 29183412 TI - Impact of sexual maturity on the welfare of immunocastrated v. entire heavy female pigs. AB - During oestrus, fattening female pigs are more prone to lameness, fractures and wounds due to mounting and agonistic behaviours of penmates. This study assessed the effect of sexual maturity on the behaviour and welfare of heavy female pigs slaughtered at 36 weeks of age (180+/-10 kg) for dry-cured ham production. An immunocastrated control group was used for comparison. In all, 56 15-week-old female pigs, individually identifiable by back tattoos were equally distributed among four pens. All animals from two pens were subject to a three-dose immunocastration schedule at 16, 20 and 32 weeks of age. Skin lesions and behaviours were assessed at 18, 23, 28, 33 and 36 weeks of age. A blood sample was collected at 20, 24, 28 and 32 weeks of age for assessing health/stress parameters and GnRH antibodies. At slaughter, ovaries were weighed, measured and histologically examined; stomachs, carcasses and lungs were scored for lesions and a further blood sample was taken. Immunocastrated pigs did not significantly differ from controls in growth rate, feed efficiency and slaughter performances (lung score, gastric score, backfat thickness). However, they showed a lower frequency of aggressive interactions at 33 and 36 weeks, lower front lesions at 28 weeks, but higher at 30 weeks; a lower haptoglobin level at 28 weeks, a lower level of cortisol and back lesions at slaughter (36 weeks). These findings suggest a low, yet not negligible, impact of sexual maturity on the welfare of heavy female pigs. PMID- 29183413 TI - Pathogens collections, biobanks and related-data in a One Health legal and ethical perspective. AB - Research on emerging infectious diseases calls for a work on collections of pathogens (including hosts or vectors from which the pathogens were isolated), related to human and animal health, to wildlife or on the environmental material. In this respect, the adoption of a One Health perspective is determined by the need for a common approach to consider the collection, storage and use of pathogens coming from human or non-human sources, and particularly when the same pathogen is taken from different environments. In response to this development, our purpose is to delineate a flexible regulation framework concerning collections of pathogens from various origins or hosts and their associated data in order to facilitate scientific work and research partnerships. The legal and ethical cutting-edge research on Biomedical Big Data is particularly stimulating when it comes to address challenges related to collections or biobanks of pathogens such as prior informed consent and accessibility, Material Transfer Agreement or benefit sharing. PMID- 29183414 TI - Effects of soluble fiber inclusion in gestation diets with varying fermentation characteristics on lactational feed intake of sows over two successive parities. AB - The effects of soluble fiber inclusion in gestation diets with varying fermentation characteristics (fermentation kinetics and short-chain fatty acids (SCFA)-profile) on lactational feed intake of sows and their piglet growth over two parities were investigated using an in vitro-in vivo methodology. After breeding, 90 multiparous Landrace sows were randomized to one of three experimental diets: the control (CON) diet, konjac flour (KF) diet or sugar beet pulp (SBP) diet. All diets had similar levels of net energy, CP, insoluble fiber and NDF, but KF and SBP diets had higher soluble fiber levels than the CON diet. During gestation, the sows were restrictively fed with three different diets, but during lactation, all the sows were similarly fed ad libitum. The three gestation diets were enzymatically hydrolyzed using pepsin and pancreatin, and enzymolyzed residues were used in in vitro fermentation. Gas and SCFA production were monitored during fermentation. After fermentation, enzymolyzed residues of KF or SBP diets resulted in higher final asymptotic gas volume than those of the CON diet. The enzymolyzed residues of KF diet were mainly part of rapidly fermented fractions, whereas those of SBP diet were mainly part of slowly fermented fractions. In addition, the acetic acid, butyric acid and total SCFA concentrations of enzymolyzed residues of KF diet were higher (P<0.01) than the control and SBP diets. In the in vivo studies, on day 90 of gestation, the KF diet sows had higher plasma SCFA concentration (P<0.05) at 4 h after feeding than the CON diet sows. Furthermore, the KF diet sows had lower plasma free fatty acid (FFA) concentration (P<0.01) at 4 h after feeding, and a lower value of homeostasis model assessment (HOMA)-insulin resistance (P<0.05), but a higher value of HOMA-insulin sensitivity (P<0.01). The KF diet sows also consumed more feed during lactation (P<0.01) and weaned significantly heavier pigs (P<0.01) than the CON diet sows. The overall results showed that the high fermentation capacity KF diet contributed to an increased lactational feed intake and improved performance of piglets in the second reproductive cycle. PMID- 29183415 TI - The pre-participation screening in young athletes: which protocol do we need exactly? AB - The aim was to assess the utility and feasibility of a comprehensive cardiac screening protocol in young athletes before participation in sports. A total of 380 athletes referring before participation in sports, between April, 2014 and April, 2015, were included in this study. The mean age was 12.4 years. A screening protocol has been applied to all, including personal and family history, physical examination, 12-lead electrocardiography, transthoracic echocardiography, 24-hour rhythm Holter analysis, and treadmill exercise test. The most frequent complaints were chest pain in 19 (5%), dyspnoea in 13 (3.4%), and dizziness and fainting in five patients (1.3%) on exercise. There was sudden death and arrhythmia in 41 patients (10.7%) owing to family history. Heart murmur was present in 20 (5.2%) and hypertension in 10 patients (2.6%) on physical examination. The 12-lead electrocardiography was abnormal in 9 patients (2.4%). The findings of transthoracic echocardiography were insignificant in 47 patients (12.3%) and in five patients (1.3%) a haemodynamically important condition was detected. The 24-hour rhythm Holter analysis was abnormal in six patients (1.5%). There were significant ST changes in two patients (0.5%) on treadmill exercise test with normal findings on myocardial perfusion scans. No significant relation was present between findings of screening protocol and transthoracic echocardiography, 24-hour rhythm Holter analysis, or treadmill exercise test results. Pre-participation screening in young athletes should consist of a targeted personal history, family history, physical examination, and 12-lead electrocardiography. Other tests should be applied only if the screening indicates the presence of a cardiovascular disease. PMID- 29183416 TI - Repair of interrupted aortic arch using autologous pulmonary artery tissue. AB - There are several options for the repair of interrupted aortic arch. Direct anastomosis may cause several problems including anastomotic site stenosis, left main bronchus compression, and acute-angled aortic arch. Interposition of a prosthetic graft has no growth potential. We present a case of 34-month-old child with interrupted aortic arch, which was repaired using a pulmonary autograft tube. PMID- 29183417 TI - Neurological soft signs significantly differentiate schizophrenia patients from healthy controls. AB - OBJECTIVE: Neurological soft signs (NSS) are a group of minor non-localisable neurological abnormalities found more often in patients with schizophrenia. The aim of the current study was to test for the effect of gender, age, parental age, age at onset and clinical symptomatology on NSS.Material and methodsThe study sample included 133 patients suffering from schizophrenia according to DSM-IV-TR (77 males and 56 females; aged 33.55+/-11.22 years old) and 122 normal controls (66 males and 56 females; aged 32.89+/-9.91 years old). The assessment included the Neurological Evaluation Scale (NES), and a number of scales assessing the clinical symptoms and adverse effects especially extrapyramidal. The statistical analysis included exploratory t-test, simple linear regression analysis, analysis of covariance and the calculation of correlation coefficients. RESULTS: The results of the current study confirm that NSS are more frequent in patients with schizophrenia in comparison with normal controls (Wilks=0.622, p<0.0001), but do not support an effect of gender, age, age at onset, paternal or maternal age, education, medication status or clinical subtype of schizophrenia on NES scores.DiscussionOverall these results suggest that NSS constitute an independent (from the rest of symptoms), core (present in the vast majority of patients) and trait (unrelated to age and probably to the stage of schizophrenia) symptom of schizophrenia which could be of value in the clinical assessment and research of schizophrenia. Overall these results are not in full accord with the literature, but they could serve to fill in gaps and inconsistencies observed so far. PMID- 29183418 TI - Defending psychiatry or defending the trivial effects of therapeutic interventions? A citation content analysis of an influential paper. AB - AIMS: Leucht et al. in 2012 described an overview of meta-analyses of the efficacy of medication in psychiatry and general medicine, concluding that psychiatric drugs were not less efficacious than other drugs. Our goal was to explore the dissemination of this highly cited paper, which combined a thought provoking message with a series of caveats. METHODS: We conducted a prospectively registered citation content analysis. All papers published before June 1st citing the target paper were independently rated by two investigators. The primary outcome coded dichotomously was whether the citation was used to justify a small or modest effect observed for a given treatment. Secondary outcomes regarded mentioning any caveats when citing the target paper, the point the citation was making (treatment effectiveness in psychiatry closely resembles that in general medicine, others), the type of condition (psychiatric, medical or both), specific disease, treatment category and specific type. We also extracted information about the type of citing paper, financial conflict of interest (COI) declared and any industry support. The primary analysis was descriptive by tabulating the extracted variables, with numbers and percentages where appropriate. Co authorship networks were constructed to identify possible clusters of citing authors. An exploratory univariate logistic regression was used to explore the relationship between each of a subset of pre-specified secondary outcomes and the primary outcome. RESULTS: We identified 135 records and retrieved and analysed 120. Sixty-three (53%) quoted Leucht et al.'s paper to justify a small or modest effect observed for a given therapy, and 113 (94%) did not mention any caveats. Seventy-two (60%) used the citation to claim that treatment effectiveness in psychiatry closely resembles that in general medicine; 110 (91%) paper were about psychiatric conditions. Forty-one (34%) papers quoted it without pointing towards any specific treatment category, 28 (23%) were about antidepressants, 18 (15%) about antipsychotics. Forty (33%) of the citing papers included data. COIs were reported in 55 papers (46%). Univariate and multivariate regressions showed an association between a quote justifying small or modest effects and the point that treatment effectiveness in psychiatry closely resembles that in general medicine. CONCLUSIONS: Our evaluation revealed an overwhelmingly uncritical reception and seemed to indicate that beyond defending psychiatry as a discipline, the paper by Leucht et al. served to lend support and credibility to a therapeutic myth: trivial effects of mental health interventions, most often drugs, are to be expected and therefore accepted.Protocol registration: https://osf.io/9dqat/. PMID- 29183419 TI - South African guideline on deep brain stimulation for Parkinson's disease. AB - BACKGROUND: Parkinson's disease (PD) is a common neurodegenerative disease, associated with severe impairment of quality of life. Although the motor aspects of the illness are typically successfully treated with medications acting on the dopaminergic system, a number of patients encounter progressive difficulties associated with their medical treatment. RECOMMENDATIONS: Carefully selected patients will benefit from deep brain stimulation (DBS) treatment for their PD. Selection requires dopamine challenge testing and neuropsychological testing for the presence of cognitive impairment. Careful follow-up and programming of the DBS system are mandatory, and a major reason for DBS failure is inadequate programming and management of medication. CONCLUSION: DBS is a useful component of standard therapy for PD and may reduce symptoms, improve quality of life, promote patient independence and reduce healthcare costs by reducing requirements for medicine. PMID- 29183422 TI - Congenital vascular anomalies of the liver. AB - Congenital vascular anomalies of the liver include a range of malformations of the portal venous, hepatic arterial and venous systems. Congenital portosystemic shunts and arteriovenous malformations make up the two most frequent such malformations. While infantile haemangiomas of the liver, endothelial tumours characterised by vascular proliferation should also be considered, as a proportion of them form prenatally. Evidence to support treatment strategies for these infants and children has been mainly based on small case series. In this review, we explore classification, clinical presentation, investigation and treatment strategies. PMID- 29183423 TI - Outcomes of Kasai hepatoportoenterostomy in children with biliary atresia in Johannesburg, South Africa. AB - BACKGROUND: Without timely surgical intervention, most children with biliary atresia (BA) are not expected to live beyond 2 years of age. The initial intervention, the Kasai hepatoportoenterostomy (KPE), aims to achieve biliary drainage. Liver transplantation (LT) is performed if jaundice fails to clear or when biliary cirrhosis occurs. In under-resourced South African (SA) academic state hospitals, KPE procedures are the standard of care for the majority of children with BA, but LT is becoming more routinely available. OBJECTIVES: To describe the outcomes of children with BA undergoing KPE, and to identify presenting clinical, laboratory and histological features that were associated with a more favourable outcome. METHODS: All children with BA who underwent KPE between January 2009 and June 2012 at the Johannesburg academic-hospital complex were included. Clinical and laboratory parameters, including paediatric end-stage liver disease (PELD) score at the time of KPE, liver histology fibrosis score, clearance of jaundice at 6 months and 24-month survival were determined. RESULTS: Of 70 children with BA diagnosed during the study period, 43 (61.4%) underwent KPE, but only 12 (27.9%) achieved early resolution of jaundice. By 24 months, 14 (32.6%) of 43 children undergoing KPE were alive with their native liver, and 2 (4.7%) other children underwent LT. PELD score <15 and early resolution of jaundice, but not age at surgery or histological fibrosis score, predicted a favourable outcome. CONCLUSION: Children with BA undergoing KPE in SA state hospitals have a poor prognosis. The PELD score at the time of KPE best predicts 24-month survival. PMID- 29183424 TI - Surgery for portal hypertension in children: A 12-year review. AB - BACKGROUND: Portal hypertension is a common and potentially devastating condition in children. Notwithstanding advances in the nonsurgical management of portal hypertension, surgery remains an important treatment modality in select patients. We report here on our experience in the past 12 years. OBJECTIVES: To describe the profile of, indication for, and complications of shunt surgery in children with portal hypertension. METHODS: Twelve children underwent shunt surgery between 2005 and 2017. Patient records were reviewed. RESULTS: Fourteen procedures were performed on 12 patients during the study period. The median age at surgery was 6.5 (range 1 - 18) years. Six patients were male. Gastrointestinal bleeding that was not amenable to endoscopic control was the most common indication for surgery. Portal vein thrombosis was the most common cause of portal hypertension in our series (n=11). Two-thirds (8/12) of all patients had an identifiable underlying risk factor for portal vein thrombosis. One-third of all patients (4/12) underwent a meso-portal bypass procedure (Rex shunt), while 58% (7/12) were managed with a distal splenorenal shunt. All patients received postoperative thromboprophylaxis. We experienced a single mortality, 1 patient experienced shunt thrombosis that required revision shunt surgery, and 2 patients experienced anastomotic strictures, with one being managed with revision surgery and the other currently awaiting radiological venoplasty. CONCLUSIONS: Surgery is a safe and important tool in the management of children with non-cirrhotic portal hypertension and those with sufficient hepatic reserve who fail to respond to more conservative methods for the treatment of side effects of portal hypertension. PMID- 29183425 TI - Graft-versus-host disease in paediatric liver transplantation: A review of the literature. AB - BACKGROUND: Graft versus host disease (GvHD) is a major complication after haematopoietic stem-cell transplantation but much less common after solid organ transplant and rare after liver transplantation. Early symptoms can resemble viral infections or drug-reactions and thus it may be under-investigated. There are no standard treatment guidelines for GvHD after paediatric liver transplantation. OBJECTIVES: To review all cases of GvHD reported to date after paediatric liver transplant. METHODS: Literature review of all English-language full-text articles published between 1990 and 2017Results. Case series articles and case reports were reviewed and collated. Symptoms, diagnostic investigations, treatments and outcomes were described for all reported cases. CONCLUSION: GvHD in paediatric liver transplantation is difficult to treat and has a high mortality, but better recognition and understanding with novel therapies available offer hope for the future. PMID- 29183426 TI - Choledochal malformations: Lessons learnt in Johannesburg. AB - BACKGROUND: Choledochal malformation (CM) is a well-described and relatively rare condition. CMs may present on antenatal ultrasound screening, through childhood and into adulthood. The aetiology is not well understood but the association with a pancreaticobiliary malunion predisposes to the development of CMs. OBJECTIVES: To review the experience of CMs in the Department of Paediatric Surgery, University of the Witwatersrand, Johannesburg to improve our patient care for this population. METHODS: After institutional ethics approval, a retrospective record review was conducted of patients presenting with CM to the Department of Paediatric Surgery, Faculty of Health Sciences, University of the Witwatersrand, Johannesburg. All patients managed between January 2010 and May 2017 were included. RESULTS: A total of 35 patients underwent surgery for CMs and 2 patients were excluded from the study owing to incomplete records. Most of our patients (83%) presented with jaundice and a median (interquartile range) bilirubin level of 167 (32 - 234) mmol/L. In our cohort of patients those with type IV lesions presented at a younger age and with higher bilirubin and gamma glutamyl transferase levels, although this finding was not statistically significant. CONCLUSION: Although uncommon, CMs may lead to significant morbidity and malignancy. Specialised care is necessary to improve longterm outcomes in these patients.

PMID- 29183435 TI - Determining need for hospitalisation: Evaluation of the utility of the CRB-65 score in patients with community-acquired pneumonia presenting to an emergency department. AB - BACKGROUND: The CRB-65 severity of illness score, used for assessing patients with community-acquired pneumonia (CAP), may be of particular benefit in resource constrained areas, since it relies purely on clinical parameters. OBJECTIVE: To assess the potential accuracy of the CRB-65 score when used in deciding whether to hospitalise patients with CAP presenting to an emergency department (ED). METHODS: Prospective, observational study in an academic hospital in Johannesburg, South Africa. Data from adult patients with radiologically confirmed CAP were analysed. RESULTS: Overall, 152 patients were enrolled (79 females, 73 males; median age 36.5 years). Several diverse criteria had been used by the ED doctors in admission decisions, while the CRB-65 score had been used in only 3/152 patients (1.6%). Overall, 68/152 patients (44.7%) had been managed as inpatients and 84/152 (55.3%) as outpatients. If the CRB-65 had been used as the sole criterion for site-of-care decisions, 107/152 patients (70.4%) would potentially have been managed as outpatients and 45/152 (29.6%) as inpatients. Achieving a stable clinical condition took longer (p=0.037) and mortality was higher (p<0.001) in patients with higher than lower CRB-65 scores. All five patients who died were inpatients. Of these, three (60.0%) would have been classified by the CRB-65 as having an intermediate mortality risk and two (40.0%) as having a high mortality risk. CONCLUSIONS: This study demonstrates the utility of the CRB-65 score in accurately determining the need for admission of patients with CAP presenting to an ED in a resource-constrained environment. PMID- 29183436 TI - The association of khat (Catha edulis) chewing and orodental health: A systematic review and meta-analysis. AB - BACKGROUND: It has been claimed that chewing khat (Catha edulis), a plant common in parts of eastern and southern Africa and the Arabian Peninsula, is associated with a range of orodental problems. OBJECTIVE: To provide a synthesis of the evidence on the association between khat chewing and orodental health. METHOD: A systematic review and meta-analysis of studies that reported on the association of khat chewing and outcomes related to orodental health identified through a systematic search using web-based electronic search engines. RESULTS: Nineteen studies were found suitable for this review. Of these, between two and five (based on the type of outcome measured) were suitable for meta-analysis. The rest were used only for qualitative synthesis. A meta-analysis of the association of khat chewing with mucosal white lesions, gum recession, periodontal pocketing and gum bleeding showed that chewing increased the odds of the respective oral problems. However, qualitative synthesis of the findings on the effect of khat chewing on oral micro-organisms showed no evidence that the practice favours the presence of pathogenic micro-organisms in the oral cavity - instead, it seems to favour the proliferation of micro-organisms compatible with orodental health. CONCLUSION: Khat chewing is associated with adverse orodental health outcomes. While literature on the topic is scarce and there is a need for generation of more evidence from different countries, on the basis of the evidence accumulated to date, public health officials and health practitioners should consider khat a threat to orodental health and take appropriate action. PMID- 29183437 TI - Investigation of adult immunodeficiency and indications for immunoglobulin replacement therapy. AB - Adults presenting with recurrent infections require an approach that allows exclusion of underlying immunodeficiency. While secondary causes of immunodeficiency are the most common, primary immunodeficiency disease (PID) may present for the first time in adults. Failure to consider this diagnosis in adults and children leads to a major diagnostic delay. Recurrent localised infections generally suggest an underlying anatomical rather than an immune defect. PIDs that are most commonly encountered include common variable immunodeficiency, immunoglobulin (Ig) A deficiency, and IgG subclass deficiency. I suggest a diagnostic approach with relevant immune tests, depending on the clinical picture. The essential role of vaccination with polysaccharide and protein antigens to evaluate B-cell functional capacity, is highlighted. Principles of management are provided, including indications for immunoglobulin replacement therapy. PMID- 29183438 TI - Investigation and management of primary immunodeficiency in South African children. AB - The primary immunodeficiency diseases (PIDs) are inherited, non-communicable diseases that cause immunological dysfunction. PIDs are seldom reported in South Africa (SA). Based on a mid-2013 population estimate of 52.98 million and assuming that the prevalence of PIDs is similar to that in well-resourced settings, the total number of individuals with PIDs in our country should range between2 850 and 45 723. However, fewer than 500 cases of PID have been reported in SA. Between five and 15 new, fully characterised PIDs are reported annually. Our understanding of the physiology of the immune system has been substantially enhanced by these discoveries, and consequently the international classification of PIDs has been updated. PMID- 29183439 TI - Advances in the diagnosis and management of allergic disease: Applications to South African practice. AB - There have been a number of advances in the diagnosis and management of allergic diseases that are relevant to South African (SA) circumstances. These are all published or about to be published in new guidelines that provide practical advice to guide SA doctors who treat patients with these conditions. The guidelines include those for atopic dermatitis, allergic rhinitis and food allergy. This article reflects the most pertinent aspects of the guidelines. It also provides a short summary of a new allergy diagnostic test available in SA, the multiplexmicroarray chip, known as the immuno-solid-phase allergen chip (ISAC) test. It provides component-resolved allergy testing for special circumstances and complex allergic problems and is certainly not required as a screening allergy test. Finally, this article gives an update on allergen immunotherapy - some patients with allergic conditions may benefit from immunotherapy. In SA, some forms of immunotherapy for allergic rhinitis and mild asthma may currently include sublingual immunotherapy. PMID- 29183440 TI - Recommendations for the use of immunoglobulin therapy for immunomodulation and antibody replacement. AB - Polyvalent immunoglobin, derived from pooled human plasma, can be administered via the intravenous, subcutaneous or intramuscular route. Therapy is standard of care in the treatment of a number of immune-mediated pathologies across disciplines. By volume, the majority is used in neurology (~40%). In primary immunodeficiencies, therapy reconstitutes humoral immunity at replacement doses (0.4 - 0.6 g/kg/month), decreasing infections, and is usually lifelong. However, high doses, usually 2 g/kg total dose over five days, are required for immunomodulation in autoimmune and inflammatory indications. A high-quality evidence base supports use in primary antibody failure, Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy, acute idiopathic thrombocytopenia, Kawasaki disease andimmunobullous diseases. Low-quality evidence shows benefit in many other uncommon autoimmune and immunodeficient conditions.In South Africa, use of immunoglobulin therapy is restricted and, given the cost involved, will likely remain so. Therefore, the incremental benefit over other forms of immunosuppression, particularly corticosteroids, must be assessed carefully on a case-by-case basis. In most cases, therapy will be second-line or 'rescue' and motivation will be required. This short review aims to provide clinicians with the necessary understanding of the therapy, general considerations for use, and evidence base and quality thereof for well established indications. PMID- 29183441 TI - Immune tolerance and immunosuppression in solid organ transplantation. AB - Organ transplantation is the treatment of choice for patients with end-stage organ failure. Most of them will require lifelong immunosuppression to prevent both acute and chronic rejection. T-cell recognition of the allograft major histocompatibility complex antigens is the central event initiating cellular rejection of the allograft, and subsequent full T-cell activation requires three signals.Immunosuppressive regimens currently used in clinical practice are nonspecific and target T-cell activation, clonal expansion or differentiation into effector T cells. While these therapeutic regimens have advanced considerably and one-year graft survival figures for most solid organ transplants (SOTs) are >90%, the long-term graft survival remains fair owing to graft loss from chronic rejection. The 'holy grail' of SOT is therefore the development of a permanent specific immune tolerance against donor allogeneic antigens without the long-term use of immunosuppression.

PMID- 29183445 TI - Paediatric liver transplantation in Johannesburg revisited: 59 transplants and challenges met. AB - BACKGROUND: A paediatric liver transplant programme was started at the Wits Donald Gordon Medical Centre, Johannesburg, South Africa (SA), in November 2005. We reported on the first 29 patients in 2012. Since then we have performed a further 30 transplants in 28 patients, having met the major challenge of donor shortage by introducing a living related donor programme and increasing the use of split liver grafts. OBJECTIVE: To review the Wits Donald Gordon Medical Centre paediatric liver transplant programme to date. We describe how the programme has evolved and specifically compare the outcomes of the first cohort with the most recent 28 patients. METHODS: Case notes of all paediatric liver transplants performed between 14 November 2005 and 30 June 2014 were retrospectively reviewed. Data were analysed for age and weight at transplantation, indication and type of graft. Morbidity and mortality were documented, specifically biliary and vascular complications. Comparison was made between Era 1 (November 2005 - October 2012) and Era 2 (November 2012 - June 2014). RESULTS: A total of 59 transplants were performed in 57 patients. Age at transplantation ranged from 9 months to 213 months (mean 82.39 months) and weight ranged from 5 kg to 62 kg (mean 21 kg). A total of 23 whole livers, 10 reduced-size grafts, 14 split liver grafts and 12 living donor liver transplants (LDLTs) were performed. Eight patients were referred with fulminant hepatic failure (FHF), all in Era 2. Of these, three patients were successfully transplanted. Of the 57 patients, 45 are alive and well with actuarial 1-year patient and graft survival of 85% and 84% and 5-year patient and graft survival of 78% and 74%, respectively. Sixteen (25.42%) biliary complications occurred in 15 of our 59 transplants. Seven patients developed significant vascular complications. Comparing Era 1 with Era 2, mean age at transplant decreased from 100.86 months to 64.73 months, mean weight from 25.2 kg to 16.9 kg, and type of graft utilised changed with a trend away from the use of whole livers and reduced-sized grafts to split livers and segment 2,3 LDLT grafts. CONCLUSION: Initially limited by a shortage of donor organs, we aggressively explored optimal utilisation, splitting liver grafts from deceased donors as often as possible and establishing an LDLT programme. This increased access to donor livers allowed us to include patients with FHF and to perform retransplantation in recipients with early graft failure. It remains to offer liver transplantation to the entire paediatric community in SA, in conjunction with the only other established paediatric liver transplant unit, at Red Cross War Memorial Children's Hospital in Cape Town. PMID- 29183446 TI - Paediatric pancreatic trauma: A review of the literature and results of a multicentre survey on patient management. AB - BACKGROUND: It is generally accepted that paediatric solid organ injury should be treated conservatively, unless there is haemodynamic instability unresponsive to resuscitation. When it comes to pancreatic trauma, there is much debate about appropriate management. OBJECTIVES: To review the literature and determine how pancreatic trauma is managed in South African (SA) tertiary institutions and compares with international standards. METHOD: A survey was emailed to 45 paediatric surgical consultants working in various paediatric surgical units in SA, Italy, England and Australia. The questionnaire comprised two scenarios of isolated pancreatic trauma (grade III), the main difference between them being the time interval between initial injury and presentation. In the first scenario, the patient presented 6 hours post injury whereas in the second scenario, the patient presented 6 days post initial injury. The survey enquired about diagnosis and subsequent work-up (including preferred imaging techniques), supportive management (including nutrition), the various options of definitive intervention and follow-up procedure. RESULTS: There were 21 responders from four different countries. In the first scenario, 10 surgeons would operate, 8 would treat conservatively and 3 would perform an endoscopic retrograde cholangiopancreatogram (ERCP) and stent. In the second scenario, 4 surgeons would operation, 13 would treat conservatively and 4 would undertake ERCP with stent. There was no difference in management between the SA surgeons and their international counterparts. CONCLUSION: Management of blunt pancreatic trauma in SA is consistent with that reported in the literature. There is still controversy regarding the optimal management of pancreatic injury involving ducts. No absolute algorithm can be used to treat these patients. All patients should be treated individually and managed with an approach and techniques that are feasible. PMID- 29183447 TI - Acute liver failure and transplantation in children. AB - Acute liver failure (ALF) was relatively easy to recognise in the days before liver transplantation became available as rescue therapy, because the diagnosis was based on end-stage disease manifestations such as profound coagulopathy, jaundice, encephalopathy and cerebral edema (in a patient with no history of chronic liver disease). These criteria no longer help us in an era when we struggle to define which patients are going to progress to this end-stage picture in the time necessary for evaluation and listing for life-saving transplantation. Ideally, identifying which patients will recover spontaneously or with appropriate treatment would relieve the justifiable concern that some patients receive a transplant when, given time, they would have recovered. Currently, the data to guide us in avoiding death without transplantation and unnecessary transplantation remain elusive. This review will focus primarily on the aspects that surround the decision to undertake liver transplantation in a child with ALF. There are many excellent chapters and journal reviews which cover specific medical management of ALF and its complications; therefore this will not be addressed in this essay. PMID- 29183448 TI - Liver tumours in children: Current surgical management and role of Transplantation. AB - This article reviews the current surgical management of liver tumours in children in the light of improved chemotherapy, surgical techniques and outcomes from transplantation. It is a principle of management that complete removal of a tumour must be achieved for cure. Neoadjuvant chemotherapy may downstage advanced local disease to enable safe curative tumour resection. When this is not achievable, transplant is indicated. Conventional indications for transplant are unresectable stages 3 and 4 tumours confined to the liver. With the realisation that lifelong immunosuppressive therapy has considerable adverse consequences, there has been a recent trend towards extreme and 'acrobatic' liver resection to avoid transplantation, but still obtain a cure. The current literature is reviewed in the light of these trends and our own experience. PMID- 29183449 TI - Controversies in choledochal malformation. AB - Choledochal malformations (some of which are choledochal cysts) may be characterised as an abnormal dilatation of the biliary tract, in the absence of acute obstruction. Most do appear to be of congenital origin, probably related to distal bile duct stenosis, and almost 15% can now be detected antenatally.Excision and biliary reconstruction using a Roux loop as an open operation is still the standard to compare against, although laparoscopic reconstruction is increasingly reported. This article discusses recent advances in the understanding of choledochal malformation aetiology and classification, together with the role of newer modalites of surgical treatment such as laparoscopic excision and biliary reconstruction. Although these are definitely feasible, care should be taken before dispensing with standard open techniques that have minimal complications and proven long-term benefit. PMID- 29183450 TI - Role of laparoscopy during surgery at the porta hepatis. AB - Minimally invasive surgery in children has evolved to the extent that complex procedures can be performed with safety, with comparable outcomes to open surgery and with the advantages of minimal scarring and less pain. In this article, we describe the latest laparoscopic techniques used at Juntendo University Hospital in Japan, for treating conditions affecting the porta hepatis, focusing on biliary atresia and choledochal cysts. We also summarise our postoperative management protocols and discuss preliminary outcomes. PMID- 29183451 TI - The role of interventional radiology in complications after paediatric liver transplantation. AB - Liver transplantation has become an established treatment in both adults and children for end-stage liver disease, acute hepatic failure and certain liver tumours. There is a significant rate of complications after all forms of liver transplantation. The interventional radiologist plays a critical role in the diagnosis and treatment of these complications. The use of image-guided, minimally invasive procedures reduces the need for surgical revision or retransplantation, and improves graft and patient survival rate. This article reviews some of the most common vascular and non-vascular complications after paediatric liver transplantation, and the interventional radiology techniques used to diagnose and treat them. PMID- 29183452 TI - Paediatric lver transplantation for children treated at public health facilities in South Africa: Time for change. AB - Paediatric liver transplantation (PLT) is the only therapeutic option for many children with end-stage chronic liver disease or irreversible fulminant hepatic failure and is routinely considered as a therapy by paediatric gastroenterologists and surgeons working in developed countries. In South Africa (SA), a PLT programme is available at Red Cross War Memorial Children's Hospital in Cape Town since November 1991, and another has rapidly developed at the Wits Donald Gordon Medical Centre in Johannesburg over the past decade. However, for most children with progressive chronic liver disease who are reliant on the services provided at public health facilities in SA, PLT is not an option because of a lack of resources in a mismanaged public health system. This article briefly outlines the services offered at Chris Hani Baragwanath Academic Hospital - which is typical of public health facilities in SA - and proposes that resources be allocated to establish an innovative, nationally funded centre that would enable greater numbers of children access to a PLT programme. PMID- 29183453 TI - The age-related characteristics of adults with asthma who visited emergency departments in Korea from 2007 to 2012. AB - BACKGROUND: Understanding the patterns of emergency department (ED) visits of patients with asthma is important for disease control and prevention of exacerbations. OBJECTIVE: This study aimed to investigate the characteristics of adult patients who visited EDs because of their asthma. METHODS: Patients with asthma, ages >=19 years old, who visited 117 EDs throughout Korea between January 2007 and December 2012 were identified in the National Emergency Department Information System (NEDIS) data base using the International Classification of Disease, 10th revision, codes J45 (asthma) and J46 (status asthmaticus). RESULTS: A total of 97,835 adult patients with asthma visited 117 EDs throughout Korea during the study period. There was a slight female preponderance (male-to-female ratio, 1:1.09). The number of patients aged 70-79-years-old was 28,031 (28.7%), the highest among the patients with asthma. ED visits showed a seasonal distribution, with most occurring in winter and spring, followed by autumn. The seasonal distribution varied by age; most patients ages 19-49 years presented in autumn (September), whereas those patients ages >=50 years presented to the ED most often in winter. Overall, 65.5% of patients were admitted to the hospital, including 12.6% admitted to an intensive care unit (ICU). Overall, 209 patients (0.2%) died. The rates of hospital admission to general wards and ICUs were highest in those patients >=70 years old; this group also had the highest mortality rate. CONCLUSION: In this nationwide study, which spanned 6 years, of adult patients with asthma, we observed an age-specific seasonal pattern of ED visits. Identifying the causes of age-related deterioration and seasonal visits to the ED will help prevent asthma symptoms and reduce medical costs. PMID- 29183454 TI - Preventing congenital rubella infection in the European Region of WHO: 2010 target. AB - The World Health Organisation (WHO) Regional Office for Europe has recently published a strategic plan and surveillance guidelines for measles and congenital rubella infection. The strategy prioritises measles control activities but encourages the introduction of rubella vaccine when measles vaccine coverage has reached >90 %; although, many western European countries with suboptimal measles vaccine coverage are already using the combined measles, mumps and rubella (MMR) vaccine. Women in these countries may have an especially high risk of having an infant with congenital rubella syndrome. WHO is seeking to improve the surveillance for rubella and congenital rubella syndrome as a means to obtain better information on the burden of these diseases and engage policy decision makers in the need to support the WHO European Region's strategies for rubella. PMID- 29183455 TI - Sentinel surveillance of HIV infection in HIV test clinics, Spain 1992-2002. AB - HIV infection in Spain was monitored in persons undergoing voluntary HIV testing in ten sentinel clinics between 1992 and 2002. Only patients on their first visit were considered for inclusion, and their numbers rose from 4426 in 1992 to 6649 in 2002. Most of them recognised their risk exposure as heterosexual. The proportion of injecting drug users decreased from 19% to 2% of the study population, and the proportion of female sex workers increased from 6% to 26%. The number of patients diagnosed with HIV infection declined from 604 in 1992 to 153 in 2002, and HIV prevalence fell from 13.6% to 2.3% in the same period. In all risk exposure categories, a decrease in HIV prevalence was observed, more pronounced during the first few years and stabilised in the later years. In 2002, the highest HIV prevalence was found in injecting drug users (IDUs) (14.2%), homo/bisexual men (7.5%) and individuals who had an HIV infected heterosexual partner (10.2%). PMID- 29183457 TI - International trends in salmonella serotypes 1998-2003 - a surveillance report from the Enter-net international surveillance network. AB - One of the objectives of any surveillance activity is to monitor trends in infections. The international surveillance network for human enteric infections, Enter-net, has been collecting and reporting data on laboratory-confirmed human salmonella infections since 1993. The number of cases identified rose in the mid 1990s, with the peak being in 1997. This paper describes the subsequent decline in salmonella serotypes being reported by the national reference laboratories participating in the Enter-net surveillance network between 1998-2003. The total number of human cases of salmonellosis reported by the Enter-net participating countries has fallen from 220 698 to 142 891 during this period. Even at these reported levels salmonellosis remains a major cause of morbidity in humans. PMID- 29183456 TI - Strengthening early warning function of surveillance in the Republic of Serbia: lessons learned after a year of implementation. AB - The Republic of Serbia, with WHO support, has implemented an early warning system (ALERT) for priority communicable diseases, to complement the routine surveillance system which notifies individual confirmed cases. The results of its evaluation, conducted one year after implementation is presented here. ALERT relies on notification of 11 syndromes by primary care facilities. Data is analysed weekly at district level and transmitted to national epidemiologists. ALERT is perceived to be a simple and flexible tool. Acceptability is higher at national level than at district level. Some districts perceive ALERT as a parallel system poorly connected to control measures. Sensitivity of ALERT in detecting cases of meningitis is 93%, and 37% for cases of hepatitis. Retrospective analysis of ALERT data identified 9 outbreaks, 5 of which had been recognized by epidemiologists. ALERT was the timeliest system for detecting 4 outbreaks identified by both systems. ALERT was useful for triggering timely investigation and control of outbreaks of hantavirus and salmonellosis and for detecting the start of the influenza season. However, ALERT did not detect clusters of brucellosis and tularaemia targeted by the unexplained fever syndrome. This evaluation underlined the need for a global review of surveillance activities when implementing new components such as ALERT. While control measures based on notification of individual confirmed cases are well understood and implemented, the investigation and verification process that should result from an increase in ALERT syndromes is not fully understood. Field epidemiology training programmes, such as the EPIET programme, are best suited to bring about this change of perspective. PMID- 29183458 TI - Dramatic shift in the epidemiology of Salmonella enterica serotype Enteritidis phage types in western Europe, 1998-2003 - results from the Enter-net international salmonella database. AB - Salmonella enterica serotype Enteritidis is the predominant salmonella serovar identified by the Enter-net national reference laboratories in western Europe. As it is the most commonly recognised serotype, it is important that phage typing is carried out so that outbreaks can be recognised and confirmed, and trends in infections identifed. Data from the Enter-net salmonella database show that there has been a dramatic shift between phage types identified in Europe from 1998 2003. In 1998, the proportion of phage type (PT) 4 was 61.8%, making it the most frequently identified phage type in humans (21 630 cases), whereas by 2003 the proportion of PT4 had fallen to 32.1% (8794 cases) with other strains increasing, both in proportion and numbers. This paper identifies the emerging strains that are becoming more relevant in public health terms. PMID- 29183459 TI - Towards a standard HIV post exposure prophylaxis for healthcare workers in Europe. AB - Antiretroviral prophylaxis (PEP) after occupational exposure to HIV in healthcare workers (HCWs) is used across Europe, but not in a consistent manner. A panel of experts, funded by the European Commission, formulated a set of recommendations. When it has been decided that the characteristics of the exposure indicate the initiation of PEP, PEP should be started as soon as possible; initiation is discouraged after 72 hours. PEP should be initiated routinely with any triple combination of antiretrovirals approved for the treatment of HIV-infected patients; a two class regimen is to be preferred. The source patient's treatment history should be sought. Counselling, psychological support, HIV testing and clinical evaluation should be performed at baseline, at 6-8 weeks, and at least 6 months post exposure. Additional clinical and laboratory monitoring at one and two weeks should be considered, as adherence with and tolerance of the regimen can highlight adverse reactions and potential toxicity. Routine HIV resistance tests in the source patient, and direct virus assays in the exposed HCW are not recommended. PMID- 29183460 TI - How to prevent transmission of MRSA in the open community? AB - In the past 20 to 30 years, methicillin-resistant Staphylococcus aureus (MRSA) strains have been present in hospitals and have become a major cause of hospital acquired infection. Methicillin resistance rates of S. aureus vary considerably between countries, with a high prevalence in the United States, and southern Europe (>20%) and a low prevalence in northern Europe (< or =5%). Community acquired MRSA emerged worldwide in the late 1990s. There has been great confusion in the literature between healthcare-associated MRSA infections occurring in the community in patients who are at risk of acquiring hospital MRSA (such as those with past history of hospital admission, immunocompromised status, etc.), and true CA-MRSA infections due to strains that are present in the community only. PMID- 29183461 TI - Rubella control in France. AB - In the pre-vaccination era, rubella was regarded as only a mild exanthematous acute viral infection of children. The devastating effects of the disease were first identified in the early 1940s by an Australian ophthalmologist, and further confirmed during the 1962-65 rubella pandemic in Europe and the United States. They result from the transmission of the virus by infected pregnant women to their fetus. The resulting congenital rubella syndrome (CRS) comprises a lengthy list of abnormalities. The most common ones are deafness, ocular and cardiac defects and mental retardation. The objective of rubella vaccination, to which France has subscribed, is the elimination of CRS [1]. PMID- 29183462 TI - Epidemiology of rubella and congenital rubella syndrome in Greece, 1994-2003. AB - In 1993, there was a large epidemic of rubella and congenital rubella syndrome (CRS) in Greece. The epidemiology of rubella and CRS after 1993 is described in this paper using information from surveillance data and published studies and reports. The incidence of rubella fell sharply after 1993, but a smaller outbreak occurred in 1999, mainly in young adults, and four CRS cases (4.0 per 100 000 live births) were recorded. A very high proportion of the child population in Greece are currently vaccinated for rubella, while teenagers are inadequately covered (60-80% in different studies). A substantial proportion of women of childbearing age are susceptible to rubella (10-20% in urban areas). This could lead to local or more extended outbreaks. This situation shows that a comprehensive preventive policy should be implemented. PMID- 29183463 TI - A large increase of Salmonella infections in 2003 in the Netherlands: hot summer or side effect of the avian influenza outbreak? AB - In June 2003, the Dutch national Salmonella centre reported a significant excess isolation rate of Salmonella Enteritidis when compared with earlier years in most regional public health laboratories. By the end of 2003, this amounted to an extra 540 laboratory confirmed cases for the whole of the Netherlands, which implies an estimated 7500 extra cases of gastroenteritis caused by S. Enteritidis in the general population, an increase of 50% on previous years. The hot summer could not explain the findings. Strong evidence has been found to suggest that the increase in importation of salmonella contaminated eggs, as a side effect of a concurrent avian influenza outbreak, was the most probable reason for this excess. PMID- 29183464 TI - The epidemiology of infectious syphilis in the Republic of Ireland. AB - In response to the increasing numbers of syphilis cases reported among men having sex with men (MSM) in Dublin, an Outbreak Control Team (OCT) was set up in late 2000. The outbreak peaked in 2001 and had largely ceased by late 2003. An enhanced syphilis surveillance system was introduced to capture data from January 2000. Between January 2000 and December 2003, 547 cases of infectious syphilis were notified in Ireland (415 were MSM). Four per cent of cases were diagnosed with HIV and 15.4% of cases were diagnosed with at least one other STI (excluding HIV) within the previous 3 months. The mean number of contacts reported by male cases in the 3 months prior to diagnosis was 4 (range 0-8) for bisexual contacts and 6 for homosexual contacts (range 1-90). Thirty one per cent of MSM reported having had recent unprotected oral sex and 15.9% of MSM reported having had recent unprotected anal sex. Sixteen per cent of cases reported having had sex abroad in the three months prior to diagnosis. The results suggest that risky sexual behaviour contributed to the onward transmission of infection in Dublin. The outbreak in Dublin could be seen as part of a European-wide outbreak of syphilis. The rates of co-infection with HIV and syphilis in Ireland are comparable with rates reported from other centres. There is a need to improve surveillance systems in order to allow real time evaluation of interventions and ongoing monitoring of infection trends. PMID- 29183465 TI - Rubella control in Italy. AB - In Italy, rubella vaccination has been recommended since 1972 for pre-adolescent girls, and since the early 1990s for all children in the second year of life. Nevertheless, coverage in children from 12 to 24 months of age is suboptimal (i.e., 56% in 1998, 78% in 2003), with wide variations among regions. As a result, rubella is still circulating in Italy, and in 1996 the percentage of women susceptible to rubella between 15 and 39 years of age was >5%. Congenital rubella syndrome (CRS) was a notifiable disease between 1987 and 1991, with a range of 8-76 cases reported annually. Since 1992, national incidence data are no longer available, but local reports show that CRS cases are still occurring. Nationwide, coordinated and uniform actions are needed to control CRS effectively. For this reason, the National Plan for the Elimination of Measles and of Congenital Rubella has recently been launched. This plan includes strategies aimed at increasing MMR vaccination coverage in children and specific control measures for congenital rubella control, i.e., improving the vaccination of susceptible women of childbearing age, and reintroducing national surveillance of CRS. PMID- 29183466 TI - New features of rubella in Spain: the evidence of an outbreak. AB - In most of western Europe the rubella vaccine coverage is high. However, prior to the introduction of the vaccine in Latin America, rubella susceptibility in women of childbearing age was 10-25%. Forty one (93%) countries in Latin America have adopted the rubella vaccine since 2002. The adult immigrant population in Spain constitutes a group of susceptibles. In February 2003, the Madrid Community Measles Elimination Plan detected an increase in rubella notifications in women who had been born in Latin America. A descriptive study was undertaken to characterise the outbreak. A confirmed case was a person with fever or rash and a positive IgM serology, and living in Madrid, between 1 December 2002 and 31 March 2003. The secondary attack rate (SAR) per household was calculated. A total of 19 cases of rubella were identified, 15 were confirmed and 4 were probable cases. Fourteen (73.7%) cases were women at childbearing age. The mean age was 25.1 years. One pregnancy was diagnosed with a voluntary termination. Eleven (57.9%) cases were from Ecuador. The mean time of residence in Spain was 41 months. None of the cases or the 54 (78.3%) household contacts had been vaccinated against rubella. The SAR was 9.1%. This study showed the spread of rubella in the susceptible Latin American Community that is resident in Madrid. The interventions proposed were a vaccination programme towards immigrants, a health education campaign to prevent congenital rubella, and a health professional training programme case management.

AB - The Eighth International Meeting of the European Laboratory Working Group on Diphtheria (ELWGD) and the Diphtheria Surveillance Network (DIPNET) was held and co-organised with the WHO Regional Office for Europe, Copenhagen, Denmark, in June 2004. This article provides an international updated review of progress in clinical, epidemiological and microbiological aspects of diphtheria in the European region as presented at the meeting. It highlights the need for improved immunisation coverage, surveillance and epidemiological studies to sustain control of diphtheria in European Region. PMID- 29183468 TI - Proposed recommendations for the management of HIV post-exposure prophylaxis after sexual, injecting drug or other exposures in Europe. AB - Post-exposure prophylaxis (PEP) is the standard of care for a healthcare worker (HCW) accidentally exposed to an HIV infected source person (occupational exposure), but this is not the case for non-occupational exposures. Very few national guidelines exist for the management of non-occupational exposures to HIV in Europe, contrarily to the occupational ones. The administration of non occupational post-exposure prophylaxis (NONOPEP) for HIV may be justified by: a biological plausibility, the effectiveness of PEP in animal studies and occupational exposures in humans, efficacy in the prevention of mother to child HIV transmission, and cost effectiveness studies. These evidences, the similar risk of HIV transmission for certain non-occupational exposures to occupational ones, and the conflicting information about attitudes and practices among physicians on NONOPEP led to the proposal of these European recommendations. Participant members of the European project on HIV NONOPEP, funded by the European Commission, and acknowledged as experts in bloodborne pathogen transmission and prevention, met from December 2000 to December 2002 at three formal meetings and a two day workshop for a literature review on risk exposure assessment and the development of the European recommendations for the management of HIV NONOPEP. NONOPEP is recommended in unprotected receptive anal sex and needle or syringe exchange when the source person is known as HIV positive or from a population group with high HIV prevalence. Any combination of drugs available for HIV infected patients can be used as PEP and the simplest and least toxic regimens are to be preferred. PEP should be given within 72 hours from the time of exposure, starting as early as possible and lasting four weeks. All patients should receive medical evaluation including HIV antibody tests, drug toxicity monitoring and counseling periodically for at least 6 months after the exposure. NONOPEP seems to be a both feasible and frequent clinical practice in Europe. Recommendations for its management have been achieved by consensus, but some remain controversial, and they should be updated periodically. NONOPEP should never be considered as a primary prevention strategy and the final decision for prescription must be made on the basis of the patient-physician relationship. Finally, a surveillance system for these cases will be useful to monitor NONOPEP practices in Europe. PMID- 29183469 TI - Report on the first PVL-positive community acquired MRSA strain in Latvia. AB - Infections by community-acquired methicillin resistant Staphylococcus aureus (CA MRSA) have been reported worldwide. Here we present characterisation of the first CA-MRSA isolated in Latvia. A PVL-positive ST30-MRSA-IV strain was isolated from a nasal swab and the central venous catheter of a patient with fever and multiple organ failure. The PFGE pattern of this strain was identical to pattern SE00-3 of MRSA isolated in Sweden from 29 patients during 2000-2003. This strain is related to the South Pacific area, and its appearance in Sweden and Latvia demonstrates its global spread. PMID- 29183470 TI - Bichat guidelines for the clinical management of glanders and melioidosis and bioterrorism-related glanders and melioidosis. AB - Glanders and melioidosis are two infectious diseases that are caused by Burkholderia mallei and Burkholderia pseudomallei respectively. Infection may be acquired through direct skin contact with contaminated soil or water. Ingestion of such contaminated water or dust is another way of contamination. Glanders and melioidosis have both been studied for weaponisation in several countries in the past. They produce similar clinical syndromes. The symptoms depend upon the route of infection but one form of the disease may progress to another, or the disease might run a chronic relapsing course. Four clinical forms are generally described: localised infection, pulmonary infection, septicaemia and chronic suppurative infections of the skin. All treatment recommendations should be adapted according to the susceptibility reports from any isolates obtained. Post exposure prophylaxis with trimethoprim-sulfamethoxazole is recommended in case of a biological attack. There is no vaccine available for humans. PMID- 29183471 TI - Bichat guidelines for the clinical management of brucellosis and bioterrorism related brucellosis. AB - Interest in Brucella species as a biological weapon stems from the fact that airborne transmission of the agent is possible. It is highly contagious and enters through mucous membranes such as the conjunctiva, oropharynx, respiratory tract and skin abrasions. It has been estimated that 10-100 organisms only are sufficient to constitute an infectious aerosol dose for humans. Signs and symptoms are similar in patients whatever the route of transmission and are mostly non-specific. Symptoms of patients infected by aerosol are indistinguishable from those of patients infected by other routes. Regimens containing doxycycline plus streptomycin or doxycycline plus rifampin are effective for most forms of brucellosis. Isolation of patients is not necessary. Trimethoprim-sulfamethoxazole and fluoroquinolones also have good results against Brucella, but are associated with high relapse rates when used as monotherapy. The combination of ofloxacin plus rifampicin is associated with good results. Even if there is little evidence to support its utility for post-exposure prophylaxis, doxycycline plus rifampicin is recommended for 3 to 6 weeks. PMID- 29183472 TI - Surveillance of Lyme borreliosis in Germany, 2002 and 2003. AB - Lyme borreliosis is a potentially serious infection common in Germany, but little data about its incidence, distribution, and clinical manifestations are available. Lyme borreliosis is not a notifiable disease in Germany, but six of Germany's 16 states - Berlin, Brandenburg, Mecklenburg-Vorpommern, Sachsen, Sachsen-Anhalt and Thuringen, have enhanced notification systems, which do include Lyme borreliosis. The efforts made in these states to monitor confirmed cases through notification are therefore an important contribution to understanding the epidemiology of Lyme borreliosis in Germany. This report summarises the analysis of Lyme borreliosis cases submitted to the Robert Koch Institut during 2002-2003. The average incidence of Lyme borreliosis of the six East German states was 17.8 cases per 100 000 population in 2002 and increased by 31% to 23.3 cases in 2003, respectively. Patient ages were bimodally distributed, with incidence peaks among children aged 5- 9 and elderly patients, aged 60- 64 in 2002, and 65- 69 in 2003. For both years, 55% of patients were female. Around 86% of notified cases occurred from May to October. Erythema migrans affected 2697 patients (89.3%) in 2002 and 3442 (86.7%) in 2003. For a vector-borne disease, like Lyme borreliosis, the risk of infection depends on the degree and duration of contact between humans and ticks harbouring Borrelia burgdorferi. As infectious ticks probably occur throughout Germany, it is likely that the situation in the remaining 10 German states is similar to that of the states in this study.

AB - Six hundred and thirty two cases of travel-associated legionnaires' disease with onset in 2003 were reported to the EWGLINET surveillance scheme by 24 countries. Eighty nine clusters were detected, 35 (39%) of which would not have been detected without the EWGLINET scheme. One hundred and seven accommodation sites were investigated and 22 sites were published on the EWGLI website. The proportion of cases diagnosed primarily by the urinary antigen test was 81.2%, and 48 positive cultures were obtained. Thirty eight deaths were reported to the EWGLINET scheme, giving a crude fatality rate of 6%. Countries are encouraged to inform the coordinating centre of cases that fall ill after travelling within their own country of residence ('internal travel'), and are also encouraged to obtain patient isolates for culture where at all possible. PMID- 29183474 TI - Quality assurance for the diagnostics of viral diseases to enhance the emergency preparedness in Europe. AB - The threat posed by emerging and re-emerging communicable diseases and, more recently, by the intentional release of infectious agents in a susceptible population, has been receiving considerable attention at the national and international levels. Public health efforts to strengthen disease detection, surveillance and control have been intensified. However, clinicians and clinical microbiology laboratories play an important role in the early detection of disease, the identification of the putative agent, and notification of the appropriate authorities. To be effective in this role, laboratories must be specially prepared to handle viral agents safely, and need, among other things, the appropriate rapid and sensitive diagnostic tests. In 1998 the European Network for Diagnostics of "Imported" Viral Diseases (ENIVD) was established. ENIVD presently comprises, as permanent members, 44 expert laboratories in 21 European Union (EU) member states and 4 non-EU countries and is one of the networks on infectious diseases funded by the European Commission. ENIVD fulfils many of the important tasks required for the surveillance and control of imported, rare and emerging viral infections such as the exchange of expertise and the organisation of external quality assurance (EQA) programmes, both of which are needed to improve diagnostics. Here, we summarise the data generated by recent EQA activities focussed on the diagnostics of infections with hantavirus, dengue virus, filovirus, Lassa virus, orthopox virus and the SARS-coronavirus (SARS-CoV). These were carried out between 1999 and 2004 and involved 93 laboratories from 41 countries, including laboratories from additional countries outside of Europe. Particularly the EU-candidate countries and Eastern neighbouring countries will be invited to join the network in the near future. A public website is available at http://www.enivd.de. PMID- 29183475 TI - Bichat guidelines for the clinical management of plague and bioterrorism-related plague. AB - Yersinia pestis appears to be a good candidate agent for a bioterrorist attack. The use of an aerosolised form of this agent could cause an explosive outbreak of primary plague pneumonia. The bacteria could be used also to infect the rodent population and then spread to humans. Most of the therapeutic guidelines suggest using gentamicin or streptomycin as first line therapy with ciprofloxacin as optional treatment. Persons who come in contact with patients with pneumonic plague should receive antibiotic prophylaxis with doxycycline or ciprofloxacin for 7 days. Prevention of human-to-human transmission via patients with plague pneumonia can be achieved by implementing standard isolation procedures until at least 4 days of antibiotic treatment have been administered. For the other clinical types of the disease, patients should be isolated for the first 48 hours after the initiation of treatment.

AB - The incorporation of varicella zoster virus (ZVV) vaccination in childhood immunisation schedules is becoming an increasingly common option in Europe. The current study forms part of the European Sero-Epidemiology Network 2 (ESEN2) organisational analysis for VZV and describes current passive immunisation policies, as well as current and proposed active immunisation strategies, and existing surveillance systems for diseases caused by the varicella zoster virus in ESEN countries. PMID- 29183477 TI - Bioterrorism, Glanders and melioidosis. AB - We note with interest the recently published guidelines for management of melioidosis and glanders. We are clinicians with extensive experience with melioidosis in Australia and Thailand and would like to express our concern at a number of inaccuracies in these guidelines. PMID- 29183478 TI - Syphilis surveillance in France, 2000-2003. AB - This article describes syphilis trends, characteristics of patients from 2000 to 2003 in France and trends of the benzylpenicillin benzathine 2.4 million UI sales from 2001 to 2003. The ongoing surveillance system for syphilis case reporting since 2001 has been set up in volunteer settings, mostly public settings where STI treatment is offered. Clinical case reporting is complemented by sexual behavioural data based on a self-administered questionnaire. From 2000 to 2003, 1089 syphilis cases were reported in France, increasing from 37 cases in 2000 to 428 in 2003. Overall, 96% of syphilis cases were in men with a mean age of 36.5 years and 70% of whom were born in France. The proportion of syphilis cases with HIV co-infection decreased over time from 60% in 2000 to 33% in 2003. The most affected area by the syphilis epidemic is the Ile-de-France region, mainly the city of Paris. The greatest proportion of syphilis cases diagnosed in men who have sex with men (MSM) were in the Ile-de-France region, where they made up 87% of cases, compared with 75% in other regions. Among the patients who completed the self-administered questionnaire on sexual behaviour, 83% reported having casual sex partners in the 3 months prior to their syphilis diagnosis. Trends in the sales of benzylpenicillin benzathine 2.4 million UI in private pharmacies are similar to those observed in the surveillance system, and increased between 2001 and 2003. In conclusion, syphilis transmission is still ongoing in France in 2003 and the role of unprotected oral sex in the transmission of syphilis should be emphasised. PMID- 29183479 TI - Bichat guidelines for the clinical management of haemorrhagic fever viruses and bioterrorism-related haemorrhagic fever viruses. AB - Haemorrhagic fever viruses (HFVs) are a diverse group of viruses that cause a clinical disease associated with fever and bleeding disorder. HFVs that are associated with a potential biological threat are Ebola and Marburg viruses (Filoviridae), Lassa fever and New World arenaviruses (Machupo, Junin, Guanarito and Sabia viruses) (Arenaviridae), Rift Valley fever (Bunyaviridae) and yellow fever, Omsk haemorrhagic fever, and Kyanasur Forest disease (Flaviviridae). In terms of biological warfare concerning dengue, Crimean-Congo haemorrhagic fever and Hantaviruses, there is not sufficient knowledge to include them as a major biological threat. Dengue virus is the only one of these that cannot be transmitted via aerosol. Crimean-Congo haemorrhagic fever and the agents of haemorrhagic fever with renal syndrome appear difficult to weaponise. Ribavirin is recommended for the treatment and the prophylaxis of the arenaviruses and the bunyaviruses, but is not effective for the other families. All patients must be isolated and receive intensive supportive therapy. PMID- 29183480 TI - An outbreak of Campylobacter jejuni enteritis in a school of Madrid, Spain. AB - An outbreak of gastroenteritis caused by Campylobacter infection was identified in May 2003 in a school in Madrid, Spain. Eighty one cases were identified in a total of 253 people studied. A retrospective cohort study showed that a custard made with ultra high temperature (UHT) milk was associated with illness (RR: 3.15; 95% CI: 1.25-7.93). The custard was probably contaminated with Campylobacter jejuni from a raw chicken prepared a day previously in the same kitchen. Our recommendations were to periodically remind the school's authorities how to act if an outbreak should be suspected, to include the monitoring of a food handler's working day in each environmental investigation in order to detect any risk behaviour; to implement microbiological analysis from the surfaces and utensils of the collective kitchens and improve the sanitary education of food handlers. PMID- 29183481 TI - Mandatory disease reporting by German laboratories: a survey of attitudes, practices and needs. AB - In 2000, the new German infectious disease control act replaced aggregate with individual case reporting. The process was facilitated by the simultaneous introduction of electronic data transfer within the public health system. Reporting laboratories have not been electronically connected to this network. A survey by means of a postal questionnaire was conducted in 2003 among 537 German medical microbiology laboratories to explore their reporting habits, preference for electronic reporting formats, and relevant software equipment. Almost 90% of the respondents indicated a reporting delay of no more than 24 hours and 45% were still manually filling in paper forms for reporting purposes. The introduction of electronic reporting formats was favoured by 74% of the laboratories although 33% were not using any microbiology-specific software and the remaining 67% listed 62 different products. Pilot projects with selected software manufacturers might help to pave the way for the implementation of a standardised electronic infectious disease reporting format in Germany. PMID- 29183483 TI - Science news. PMID- 29183482 TI - Measles outbreak in the Provence - Alpes - Cote d'Azur region, France, January - July 2003. AB - At the end of May 2003, the Marseilles Hospital Centre's virology laboratory informed the French public heath institute of 5 cases of confirmed measles among young adults living in Marseilles. An investigation was conducted, consulting different community and hospital health services, to determine the virus circulation in the Provence-Alpes-Cote d'Azur (PACA) region by the southern interregional epidemiological cell. The investigation identified 259 cases: 183 clinical, 74 serologically confirmed and 2 epidemiologically linked cases. The first cases were identified during the first six months of 2003, with a peak in April. This outbreak of measles in the PACA region was favoured by poor vaccination coverage, which created groups of susceptible population. The real number of cases was probably higher than the number identified. This investigation has outlined the limitations of the measles surveillance system in France: the sentinel network had not detected any case for this period. France needs to reach the WHO objective of measles elimination by 2010 and the surveillance tools used must be those already used in the most countries that are furthest advanced in the elimination process. To reach this goal, the Direction Generale de la Sante has nominated a working group to be in charge of proposing a national plan to interrupt indigenous measles transmission in France. PMID- 29183484 TI - Bichat guidelines for the clinical management of smallpox and bioterrorism related smallpox. AB - Smallpox is a viral infection caused by the variola virus. It was declared eradicated worldwide by the Word Health Organization in 1980 following a smallpox eradication campaign. Smallpox is seen as one of the viruses most likely to be used as a biological weapon. The variola virus exists legitimately in only two laboratories in the world. Any new case of smallpox would have to be the result of human accidental or deliberate release. The aerosol infectivity, high mortality, and stability of the variola virus make it a potential and dangerous threat in biological warfare. Early detection and diagnosis are important to limit the spread of the disease. Patients with smallpox must be isolated and managed, if possible, in a negative-pressure room until death or until all scabs have been shed. There is no established antiviral treatment for smallpox. The most effective prevention is vaccination before exposure. PMID- 29183485 TI - Bichat guidelines for the clinical management of tularaemia and bioterrorism related tularaemia. AB - Francisella tularensis is one of the most infectious pathogenic bacteria known, requiring inoculation or inhalation of as few as 10 organisms to initiate human infection. Inhalational tularaemia following intentional release of a virulent strain of F. tularensis would have great impact and cause high morbidity and mortality. Another route of contamination in a deliberate release could be contamination of water. Seven clinical forms, according to route of inoculation (skin, mucous membranes, gastrointestinal tract, eyes, respiratory tract), dose of the inoculum and virulence of the organism (types A or B) are identified. The pneumonic form of the disease is the most likely form of the disease should this bacterium be used as a bioterrorism agent. Streptomycin and gentamicin are currently considered the treatment of choice for tularemia. Quinolone is an effective alternative drug. No isolation measures for patients with pneumonia are necessary. Streptomycin, gentamicin, doxycycline or ciprofloxacin are recommended for post-exposure prophylaxis. PMID- 29183486 TI - Epidemiological and virological assessment of influenza activity in Europe during the 2003-2004 season. AB - The 2003-2004 influenza season in Europe was dominated by the spread of the new drift variant A/Fujian/411/2002 (H3N2)-like virus which was not perfectly matched with the A(H3N2) component of the influenza vaccine. Sporadic cases of this virus were detected in Europe at the end of the 2002-2003 season and influenza activity associated with this virus began relatively early during the 2003-2004 season. Generally, influenza activity first occurred in the west of Europe (Ireland, the United Kingdom and the Iberian Peninsula) in October/November and gradually moved east across Europe, affecting Latvia, Lithuania and Poland during the months of January and February 2004. In general, the intensity of clinical activity was higher than during the 2002-2003 season (in 13 out of 20 networks) and, in countries reporting age specific data, the highest consultation incidences were observed among children aged 0-14. However, despite the emergence of the A(H3N2) drift variant, clinical incidences were not especially high compared with historical data. The composition of the 2004-2005 influenza vaccine has been modified compared with the 2003-2004 season and includes an A/Fujian/411/2002 (H3N2)-like virus strain and a new B virus strain (a B/Shanghai/361/2002-like virus). PMID- 29183487 TI - Bichat guidelines for the clinical management of botulism and bioterrorism related botulism. AB - Botulism is a rare but serious paralytic illness caused by botulinum toxin, which is produced by the Clostridium botulinum. This toxin is the most poisonous substance known. It 100 000 times more toxic than sarin gas. Eating or breathing this toxin causes illness in humans. Four distinct clinical forms are described: foodborne, wound, infant and intestinal botulism. The fifth form, inhalational botulism, is caused by aerosolised botulinum toxin that could be used as a biological weapon. A deliberate release may also involve contamination of food or water supplies with toxin or C. botulinum bacteria. By inhalation, the dose that would kill 50% of exposed persons (LD50) is 0.003 microgrammes/kg of body weight. Patients with respiratory failure must be admitted to an intensive care unit and require long-term mechanical ventilation. Trivalent equine antitoxins (A,B,E) must be given to patients as soon as possible after clinical diagnosis. Heptavalent human antitoxins (A-G) are available in certain countries. PMID- 29183488 TI - Impact of the meningococcal C conjugate vaccine in Spain: an epidemiological and microbiological decision. AB - The new meningococcal C conjugate vaccine became available in Spain and was included in the infant vaccination schedule in 2000. A catch-up campaign was carried out in children under six years of age. As a consequence, the incidence of meningococcal disease caused by serogroup C has fallen sharply during the last three epidemiological years in Spain. The risk of contracting serogroup C disease in 2002/2003 fell by 58% when compared with the season before the conjugate vaccine was introduced. There was also an important decrease in mortality. Three deaths due to serogroup C occurred in the age groups targeted for vaccination in 2002/2003, compared with 30 deaths in the same age groups in the season before the launch of the vaccine campaign. In the catch-up campaign the vaccine coverage reached values above 92%. For the 2001, 2002 and 2003 routine childhood immunisation programme coverage values ranged from 90% to 95%. During the past three years a total of 111 cases of serogroup C disease have been reported in patients in the vaccine target group. Most of the vaccination failures occurred during the epidemiological year 2002/2003. Eight (53%) vaccine failures occurred in children who had been routinely immunised in infancy, and could be related to a lost of protection with time since vaccination. The isolation of several B:2a:P1.5 strains (ST-11 lineage) is noteworthy. These may have their origin in C:2a:P1.5 strains which, after undergoing genetic recombination at the capsular operon level, express serogroup B. These strains could have relevant epidemic potential. PMID- 29183489 TI - Suspected SARS patients hospitalised in French isolation units during the early SARS epidemic: The French experience. AB - During the SARS epidemic, many patients were screened according to WHO criteria but never went on to develop SARS. In May 2003, early in the epidemic, we conducted a retrospective study to describe suspected SARS patients hospitalised in France and compared them with documented cases of patients with SARS to evaluate the screening strategy. A total of 117 patients were studied. Only 3.4% had been in close contact with a SARS patient but 73.5% came from an affected area. 67.5% had fever and respiratory symptoms on their admission to hospital. 49.6% had fever and non specific symptoms. Clinical symptoms that were significantly more common among patients with SARS were fever, myalgia, dyspnoea, and nausea or vomiting. Presumed viral fever and respiratory tract infection were the most common diagnosis. Symptoms cannot be distinguished from an early stage of SARS confirming the usefulness of the WHO case definitions in isolation decision to avoid further transmission. PMID- 29183490 TI - Rubella in Denmark. AB - An average of 20 000 rubella cases were recorded annually in Denmark until 1987. In 1989, however, only 1006 cases were reported, and the true current incidence of rubella infection in Denmark is unknown but considered to be very low and <1 per 100 000 population. The significant decrease in the inci-dence of rubella mirrors the success of vaccination of rubella seronegative women of childbearing age, which was initiated in Denmark in 1980. From 1982 and onwards the national health security scheme also refunded vaccina-tion of children and the MMR vaccine was introduced in the Danish child-hood vaccination program in 1987. The low incidence has been sustainable due to these interventions, and since 1994 congenital rubella syndrome and rubella in pregnancy have been listed as notifiable infectious diseases in Denmark. Nevertheless, in order to meet the WHO goal of control of rubella in the Region, the introduction of mandatory reporting of all laboratory diagnosed rubella cases is now being considered. PMID- 29183491 TI - Basic Surveillance Network, a European database for surveillance data on infectious diseases. AB - The Basic Surveillance Network was started in 2000 and is one of the networks on infectious diseases funded by the European Commission. The network collects and makes readily available basic surveillance data on infectious diseases from all the 'old' (pre-2004) European Union member states. The aim is to provide easy access to descriptive data that already exist in national databases, so that it is possible to monitor and compare incidence trends for infectious diseases in the EU member states. The list of diseases covered by the network has recently been expanded from 10 initial 'pilot' diseases to over 40 diseases listed by the EU to be under surveillance. In the near future, the new member states will be invited to participate in the network. Data are case-based and comprise date of onset of disease, age and sex. Only a very short list of disease specific additional variables, such as country of infection or immunisation status, is collected. Classification of cases ( possible, probable, confirmed) is specified according to EU case definitions. The participants of the network have access to an internal web site were all the data is presented in tables and graphs. An open website is available for the public at https://www.eubsn.org./BSN/. PMID- 29183492 TI - Residual risk of transfusion-transmitted viral infections in Spain, 1997-2002, and impact of nucleic acid testing. AB - Estimates of the risk of bloodborne viral infections are essential for monitoring the safety of the blood supply and the impact of new screening tests. Incidence rates of seroconversion and the residual risk for HBV, HIV and HCV were calculated among Spanish repeat donors between 1997 and 1999 at 22 blood donation centres, and at 7 centres between 2000 and 2002. The residual risk per million donations was estimated to be 18.67 for HBV, 2.49 for HIV and 10.96 for HCV (between 1997 and 1999). For the 2000-2002 period, the residual risk per million donations was estimated to be 9.78 for HBV, 2.48 for HIV and 3.94 for HCV. Between 1999 and 2003, about 3.4 million donations were tested by NAT, mainly in pools of 44 donations, in 12 of the 22 Spanish blood donation centres participating in the study. Eight anti-HCV negative and HCV-RNA positive donations were found, which represent an approximate yield of 1/420 000, versus a projected yield of 1/240 000 obtained from 1995-1997 data. The residual risks of transfusion-transmitted viral infections in Spain were low, and with the implementation of NAT these risks are even lower. PMID- 29183493 TI - Bichat clinical guidelines for bioterrorist agents. AB - The deliberate release of anthrax in the United States shortly after the terrorist attacks of 11 September 2001 brought about a radical change in people's perception of the risk of bioterrorism. These bioterrorist events, unlike others before, had a worldwide impact not only in respect of security and public health but also in other sectors. Governments and international entities with responsibilities related to maintenance of peace, security, safety and health protection reviewed urgently their political, economic, diplomatic, military and legal means to face up to such attacks and embarked upon major efforts to increase their preparedness. PMID- 29183494 TI - Recent syphilis trends in Belgium and enhancement of STI surveillance systems. AB - Over the past five years, a series of syphilis outbreaks mainly occurring among gay men have been observed in Europe. One of these outbreaks was reported in the city of Antwerp, Belgium, during the first quarter of 2001. This outbreak is still ongoing in 2004. Furthermore, active syphilis diagnoses reported by the Sentinel Laboratory Network rose by 89% in the country during the fourth quarter of 2003. An increase in Brussels was also observed during the same quarter (+300%; 24 cases reported). Overall, the sentinel network of clinicians reported that 93.4% of patients were male; among them, 79.9% were men having sex with men (MSM). The overall proportion of patients co-infected with HIV was 50.5% (MSM: 58.6%; male heterosexuals: 23.8%; females: 8.3%); 76.1% of co-infected patients were already aware of their HIV infection at the time they were diagnosed with syphilis. PMID- 29183495 TI - Hepatitis A outbreak among MSM linked to casual sex and gay saunas in Copenhagen, Denmark. AB - During an outbreak of hepatitis A predominantly among men who have sex with men (MSM) in Copenhagen, Denmark, in 2004, we did a case-control study to determine risk factors for infection. A case was an MSM >17 years, living in Copenhagen, with IgM positive hepatitis A infection diagnosed between June and August 2004, and without a household contact with a hepatitis A case before onset of illness. Controls were selected at the Copenhagen Pride Festival. The study included 18 cases and 64 controls. Sixteen of 18 cases and 36/63 controls had sex with casual partners (ORMH 5.6, 95% CI 1.2-26.9). Eleven of 18 cases and 14/62 controls had sex in gay saunas (ORMH 4.2, 95% CI 1.5-11.5). Sex at private homes appeared to be protective (ORMH 0.2, 95% CI 0.1-0.7). Casual sex including sex in gay saunas was an important risk factor for the spread of HAV among MSM in Copenhagen. The results are in accordance with findings in other European outbreaks. As the general immunity to hepatitis A decreases and the outbreak potential increases, we recommend health education and hepatitis A vaccination to all MSM not living in monogamous relationships, especially if they visit gay saunas or other places with frequent partner change. To stop spread of hepatitis A among MSM in Europe, a European consensus on prevention and control measures may be required. PMID- 29183496 TI - Impact of nucleic acid amplification technology (NAT) in Italy in the three years following implementation (2001-2003). AB - The use of NAT technology to screen blood donations in Italy became mandatory on 28 June 2002, but had been available experimentally since 2001. During the transition period, an EIA test to detect hepatitis C core antigen (HCVcoreAg) had also been permitted. Considering the large number of blood transfusion centres in Italy, an initial reorganisation of the biological validation of blood units was necessary, with a partial centralisation of NAT testing. The Gruppo Italiano per lo Studio delle Malattie Trasmissibili con la Trasfusione (Italian Group for the Study of Transfusion-Transmissible Diseases) conducted a national survey evaluating NAT testing, based on an annual collection of data through a questionnaire sent to all centres. In the first three years of the investigation, 219 blood transfusion centres returned the questionnaires. In the period between January 2001 and December 2003, 3 894 894 blood donations were investigated for HCV RNA and 2 186 468 for HIV RNA. Of these, 12 were found to be HCV RNA positive and four HIV RNA positive, with an observed NAT versus antibody-based assay yield of 3.1/106 donations for HCV and 1.8/106 donations for HIV, respectively. Five of the 12 HCV RNA positive and anti-HCV negative donors had abnormal ALT values and their donations would have been discarded even in absence of NAT testing. Thus the final NAT yield for HCV is 1.79/106. The residual risk for HCV or HIV transmission by blood transfusion after NAT implementation is currently estimated to be extremely low in Italy. PMID- 29183497 TI - Interruption of measles transmission in Gipuzkoa (Basque Country), Spain. AB - Measles vaccine was introduced in Gipuzkoa (Basque country, Spain) in 1978 and was replaced by the measles, mumps, and rubella (MMR) vaccine for children aged 12-15 months in 1981. A second dose of the MMR vaccine was introduced in 1992. Both doses of the MMR vaccine were well accepted by the population and high coverage was achieved (95% and 91% for the first and second doses respectively for the period 1993-2002). Measles virus circulation was interrupted in the second half of the 1990s: no cases of indigenous measles were notified between 1998 and 2003, and only imported cases have been confirmed during this period. These data indicate that the measles vaccination programme implemented has been effective. Nevertheless, to avoid measles outbreaks following viral introduction, high MMR vaccine coverage levels for the two doses have to be maintained (>95%). PMID- 29183498 TI - Current situation of human diphyllobothriasis in Europe. AB - Diphyllobothriasis, a parasitosis caused by the flatworm Diphyllobothrium latum, is contracted by consuming raw or undercooked freshwater fish. The aim of this study was to evaluate the situation of this parasitosis during the past 20 years in Europe through the analysis of databases and search engines (Medline, Cabi Helminthological abstracts,Yahoo, Google), and through a questionnaire sent to a network of European parasitologists and to microbiological laboratories located on the shores of the large Alpine lakes. This study has shown that several dozen cases have been reported each year in Finland and Sweden, that there have been numerous cases in the French or Italian speaking areas of subalpine lakes, and that sporadic cases only have been observed in Austria, Spain, Greece, Romania, Poland and Norway. Over 30 cases have been identified on the Swiss shores of Lake Maggiore since 1990, and 70 cases on the Swiss and French shores of Lake Leman between 1993 and 2002. Eight to 12% of perch fillets from Lake Leman and 7.8 % of perch from Lake Maggiore were infested with larvae. Contamination sources include marinated fish fillets in northern Europe, 'carpaccio di persico' in northern Italy, and perch and charr consumed raw or undercooked around Lake Leman. Factors allowing the continuation of the parasitic cycle include the continued dumping of wastewater into lakes, yachtsmen who also fish, and a possible animal reservoir. PMID- 29183499 TI - Bichat guidelines for the clinical management of anthrax and bioterrorism-related anthrax. AB - The spore-forming Bacillus anthracis must be considered as one of the most serious potential biological weapons. The recent cases of anthrax caused by a deliberate release reported in 2001 in the United States point to the necessity of early recognition of this disease. Infection in humans most often involves the skin, and more rarely the lungs and the gastrointestinal tract. Inhalational anthrax is of particular interest for possible deliberate release: it is a life threatening disease and early diagnosis and treatment can significantly decrease the mortality rate. Treatment consists of massive doses of antibiotics and supportive care. Isolation is not necessary. Antibiotics such as ciprofloxacin are recommended for post-exposure prophylaxis during 60 days. PMID- 29183500 TI - Outbreaks caused by parvovirus B19 in three Portuguese schools. AB - This paper reports the study of outbreaks of an acute exanthematous disease among children of three schools in the municipality of Braga (Portugal). Laboratory tests were performed for five cases, showing that the disease was not due to infection by measles or rubella virus, and infection with parvovirus B19 was confirmed. There were 41 cases in children: 12 in the kindergarten, 17 in the secondary school and 12 in the primary school. There was only one case in a staff member, who worked in the kindergarten. Eight cases were identified among household contacts; two of them were brothers, one from the kindergarten and another from the secondary school, where the outbreak occurred after the kindergarten outbreak. The estimated values of the basic reproduction number R0 were very low and it is very likely that asymptomatic infectious cases have occurred. The local health authority produced written documents and met with staff members and parents. Primary healthcare facilities and the obstetric department of the local hospital were also informed. As we are approaching the elimination of measles in Portugal and the rest of Europe, with very high vaccine coverage, it is very likely that a high proportion of infectious non-vesicular exanthemas will be due to B19 infections. This is to be taken into account in the design and conduct of surveillance activities, in the context of measles and rubella elimination programmes. PMID- 29183519 TI - Abdominal Trauma Revisited. AB - Although abdominal trauma has been described since antiquity, formal laparotomies for trauma were not performed until the 1800s. Even with the introduction of general anesthesia in the United States during the years 1842 to 1846, laparotomies for abdominal trauma were not performed during the Civil War. The first laparotomy for an abdominal gunshot wound in the United States was finally performed in New York City in 1884. An aggressive operative approach to all forms of abdominal trauma till the establishment of formal trauma centers (where data were analyzed) resulted in extraordinarily high rates of nontherapeutic laparotomies from the 1880s to the 1960s. More selective operative approaches to patients with abdominal stab wounds (1960s), blunt trauma (1970s), and gunshot wounds (1990s) were then developed. Current adjuncts to the diagnosis of abdominal trauma when serial physical examinations are unreliable include the following: 1) diagnostic peritoneal tap/lavage, 2) surgeon-performed ultrasound examination; 3) contrast-enhanced CT of the abdomen and pelvis; and 4) diagnostic laparoscopy. Operative techniques for injuries to the liver, spleen, duodenum, and pancreas have been refined considerably since World War II. These need to be emphasized repeatedly in an era when fewer patients undergo laparotomy for abdominal trauma. Finally, abdominal trauma damage control is a valuable operative approach in patients with physiologic exhaustion and multiple injuries. PMID- 29183520 TI - The Effect of Sarcopenia on Outcomes in Geriatric Blunt Trauma. AB - Elderly patients are at a higher risk of morbidity and mortality after trauma, which is reflected through higher frailty indices. Data collection using existing frailty indices is often not possible because of brain injury, dementia, or inability to communicate with the patient. Sarcopenia is a reliable objective measure for frailty that can be readily assessed in CT imaging. In this study, we aimed to evaluate the effect of sarcopenia on the outcomes of geriatric blunt trauma patients. Left psoas area (LPA) was measured at the level of the third lumbar vertebra on the axial CT images. LPA was normalized for height (LPA mm2/m2) and after stratification by gender, sarcopenia was defined as LPA measurements in the lowest quartile. A total of 1175 patients consisting of 597 males and 578 females were studied. LPAs below 242.6 mm2/m2 in males and below 187.8 mm2/m2 in females were considered to be sarcopenic. We found sarcopenia in 149 males and 145 females. In multivariate analysis, sarcopenia was associated with a higher risk of in-hospital mortality (odds ratio [OR]: 1.61, 95% confidence interval [CI]: 1.01-2.56) and a higher risk of discharge to less favorable destinations (OR: 1.42, 95% CI: 1.05-1.97). Lastly, sarcopenic patients had an increased risk of prolonged hospitalization (hazard ratio: 1.21, 95% CI: 1.04-1.40).

Furthermore, in cases of severe cholecystitis in which marked inflammation leads to fibrosis, we perform subtotal cholecystectomy (SC), i.e., incomplete gallbladder resection. Laparoscopic SC (LSC) without cystic duct dissection is considered to be effective at reducing the incidence of serious complications in patients with severe cholecystitis. The cases of 246 patients who underwent cholecystectomy for benign gallbladder disease between January 2011 and May 2015 were evaluated retrospectively. Of these patients, 14 were treated with LSC, and 19 underwent OC. Moreover, three patients in the LSC group underwent LSC without cystic duct ligation because it was considered that it would be difficult to dissect and ligate the cystic duct. The LSC group suffered significantly less intraoperative blood loss than the OC group. However, the operative times of the two groups were similar. Moreover, the duration of the postoperative hospitalization period was significantly shorter in the LSC group than in the OC group. Next, we compared the long-term outcomes of the SC and total cholecystectomy groups, regardless of the surgical method. No cases of cholecystitis or gallbladder cancer were encountered in either group. It is suggested that LSC is safe, effective, and helps to prevent serious complications in cases of severe cholecystitis that require conversion to OC, regardless of whether cystic duct ligation is performed. PMID- 29183523 TI - Hypoalbuminemia and Clinical Outcomes: What is the Mechanism behind the Relationship? AB - Albumin has a number of important physiologic functions, which include maintaining oncotic pressure, transporting various agents (fatty acids, bile acids, cholesterol, metal ions, and drugs), scavenging free oxygen radicals, acting as an antioxidant, and exerting an antiplatelet effect. Hypoalbuminemia in adults, defined by an intravascular albumin level of <3.5 g/dL, is associated with poor postoperative outcomes in patients undergoing surgical intervention. Although the relationship of hypoalbuminemia and poor surgical outcome has been known for many years, the pathophysiology behind the relationship is unclear. Three theoretical constructs might explain this relationship. First, albumin might serve as a nutritional marker, such that hypoalbuminemia represents poor nutritional status in patients who go on to experience poor postoperative outcomes. Second, albumin has its own pharmacologic characteristics as an antioxidant or transporter, and therefore, the lack of albumin might result in a deficiency of those functions, resulting in poor postoperative outcomes. Or third, albumin is known to be a negative acute phase protein, and as such hypoalbuminemia might represent an increased inflammatory status of the patient, potentially leading to poor outcomes. A thorough review of the literature reveals the fallacy of these arguments and fails to show a direct cause and effect between low albumin levels per se and adverse outcomes. Interventions designed solely to correct preoperative hypoalbuminemia, in particular intravenous albumin infusion, do little to change the patient's course of hospitalization. While surgeons may use albumin levels on admission for their prognostic value, they should avoid therapeutic strategies whose main endpoint is correction of this abnormality. PMID- 29183522 TI - Peripheral Nerve Injury during Abdominal-Pelvic Surgery: Analysis of the National Surgical Quality Improvement Program Database. AB - Peripheral nerve injury (PNI) is a rare but preventable complication of surgery. We sought to assess whether the use of minimally invasive surgery (MIS) affects the occurrence of PNI. Using the American College of Surgeons National Surgical Quality Improvement Program database, we examined rates of PNI among patients undergoing appendectomy, hysterectomy, colectomy, or radical prostatectomy between 2005 and 2012. We assessed the effect of MIS, as compared with open surgery, on PNI occurrence using logistic regression. Among 297,532 patients, of whom 175,884 (59.1%) underwent MIS, the rate of PNI was 0.03 per cent. Forty-four patients treated using MIS had PNI (0.03%) as compared with 63 who underwent open surgery (0.05%; P = 0.0002). There was a significant decrease in the proportion of surgeries resulting in PNI (P < 0.0001) over time. In univariate analysis, MIS was associated with a decreased occurrence of PNI (odds ratio 0.48, 95% confidence interval 0.33-0.71), but this became nonsignificant on multivariable analysis (odds ratio 0.71, 95% confidence interval 0.47-1.09). Increased operative time and smoking status were the only factors independently associated with an increased risk of PNI on multivariable analysis. MIS techniques during common abdominal-pelvic surgeries do not appear to increase the risk of PNI. Prolonged operative time and smoking are independently associated with an increased risk of PNI. Quality improvement initiatives to increase awareness of PNI and identify patients at increased risk of this preventable complication should be considered. PMID- 29183524 TI - The Place of Elastography in Evaluating the Efficacy of Radiofrequency Ablation of Thyroid Nodules. AB - The usage of radiofrequency ablation (RFA) therapy and elastography to treat thyroid nodules has been increasing recently. Elastography specifically measures the stiffness of tissue using ultrasonography (US). The aim of the present study was to evaluate the relationship between the elastography values of thyroid nodules and the efficacy of RFA therapy. Ultrasonography was performed on 49 patients who had a thyroid nodule with a diameter of 1 cm or greater before RFA therapy. The RFA was performed under local anesthesia, and elastography was used to measure the stiffness of the normal thyroid tissue, sternocleidomastoid muscle (SCM) and thyroid nodules three months after RFA. The nodule diameter significantly decreased three months after RFA (P < 0.05). According to a cross evaluation of the mean elastography rates, the thyroid/SCM and nodule/thyroid elastography rates had an inverse relationship (P: 0.009). However, the thyroid/SCM elastography rates and nodule/SCM elastography rates (P: 0.022) and the thyroid/SCM elastography rates and the rates of reduction (%) of the nodule diameter before and three months after RFA (P: 0.016) had positive relationships. In conclusion, RFA therapy is more effective in patients with thyroid nodules if there are high thyroid tissue/SCM rates in elastography. PMID- 29183525 TI - Varying Presentations and Outcomes of Septic Shock: Should Septic Shock Be Stratified? AB - Recent studies have revealed there are three presentations of septic shock in patients: refractory hypotension without hyperlactatemia, hyperlactatemia without refractory hypotension, and both refractory hypotension and hyperlactatemia. In this study, we sought to identify differences in the outcomes of septic shock patients with these three presentations. We performed a secondary analysis of a large-scale, multicenter, controlled trial. The septic shock patients were categorized into the following three groups according to the presence or absence of refractory hypotension and hyperlactatemia: a hypotension group (refractory hypotension without hyperlactatemia), a hyperlactatemia group (hyperlactatemia without refractory hypotension), and a typical group (both refractory hypotension and hyperlactatemia). The 90-day all-cause mortality was compared among these three groups. A total of 1588 septic shock patients were enrolled in the present study, including 854 (53.8%) in the hypotension group, 477 (30.0%) in the hyperlactatemia group, and 257 (16.2%) in the typical group. The 90-day all-cause mortality were 12.3 per cent for the patients in the hypotension group, 23.1 per cent for those in the hyperlactatemia group, and 31.9 per cent for those in the typical group, these differences among the three groups were significant (Pearson's chi2 = 58.49, P < 0.001). And also, there was a significant difference between hyperlactatemia group and typical group (Pearson's chi2 = 6.77, P < 0.05). In this study, we demonstrated that the three different presentations of septic shock resulted in significantly different outcomes, suggesting that septic shock should be stratified. PMID- 29183526 TI - Do Transferred Patients Increase the Risk of Venous Thromboembolism in Trauma Centers? AB - Trauma patients often require initial stabilization followed by transfer for ongoing trauma care. Thus, the administration of VTE prophylaxis is often delayed until admission to the receiving hospital. It is unclear if transfer status is a risk factor for VTE. The National Trauma Database v6.2 was used to identify patients admitted to Level I and II trauma centers. Exclusions included patients on anticoagulation, <18 years, known VTE before trauma, or pregnant. Patients transferred were compared with nontransferred patients. Analysis included 736,374 patients with 189,166 (25.69%) transferred patients within 24 hours of injury. Using weighted measures, VTE was identified in 11,619 (1.50%) patients. The VTE rate was significantly higher in the transferred group compared with the nontransferred group (1.73% vs 1.42%, P = 0.002) including deep venous thrombosis (1.39% vs 1.14%, P = 0.004) and pulmonary embolism (0.45% vs 0.39%, P = 0.003). Multivariable analyses adjusting for patient-level risk factors demonstrated that transfer was associated with a higher likelihood of VTE (aOR 1.18; 95% CI: 1.09 1.28, P <= 0.001), pulmonary embolism (aOR 1.21; 95% CI: 1.11-1.33, P <= 0.001), and deep venous thrombosis (aOR 1.17; 95% CI: 1.07-1.28, P = 0.0004). Transfer status of trauma patients is a risk factor for VTE. Accepting a transferred patient results in an increased VTE risk and may not be reflective of the quality of care at the receiving facility. PMID- 29183527 TI - Surgical Outcomes in Hepatitis C Virus-Related Hepatocellular Carcinoma: Special Reference to Sustained Virological Responses to Interferon Therapy. AB - Long-term surgical outcomes after hepatic resection for hepatitis C virus (HCV) related hepatocellular carcinoma (HCC) in patients who achieved a sustained virological response (SVR) to interferon (IFN) therapy remain inconclusive. Clinical records of 277 patients who underwent hepatic resection for HCV-related early stage HCC (met the Milan criteria) between 1993 and 2012 were retrospectively reviewed. Thirty-seven patients achieved the SVR during HCC detection (pre-SVR group), whereas 23 achieved SVR using adjuvant interferon therapy after hepatic resection (post-SVR group). The control group included remaining 217 patients. We investigated the SVR effects on surgical outcomes. Disease-free survival (DFS) rates at 5/10/15 years after hepatic resection were significantly greater in the pre and post-SVR groups than in the control group (46/30/30per cent and 61/36/27 per cent vs 23/7/7 per cent, respectively; P < 0.001). Overall survival (OS) rates at 10/15 years after hepatic resection were better in the pre- and post-SVR groups than in the control group (68/68 percent and 78/78 per cent vs 13/11 per cent, respectively; P < 0.001). On multivariate analysis, pre- and post-SVR were independent factors for no recurrence (pre-SVR: hazard ratio (HR), 0.48, P = 0.002; post-SVR: HR, 0.41, P = 0.001) and improved survival (pre-SVR: HR, 0.36, P = 0.002; post-SVR: HR, 0.122, P < 0.001). Achievement of SVR in patients with HCV-related HCC was associated with long-term disease-free survival and OS after hepatic resection. PMID- 29183528 TI - Conditional Survival-Based "Abbreviated" Routine Cancer Surveillance for Pathologic Stage IB Melanoma. AB - A negative sentinel lymph node biopsy (SLNB) for stage IB (T1b/T2a N0) melanoma would predict an excellent long-term prognosis. Combined with the concept of conditional survival, an "abbreviated" cancer surveillance strategy was implemented to reduce the number of visits and total length of follow-up. Retrospective review of all pathologic stage IB melanoma patients (negative SLNB) at a single institution between 2006 and 2008 after implementation of an "abbreviated" cancer surveillance; clinic visits every six months for five years followed by one annual visit (total follow-up six years). Patient demographics, tumor characteristics, and information regarding recurrences were obtained. Recurrence-free, disease-specific, and overall survival were calculated. Eighty seven patients underwent the "abbreviated" cancer surveillance. Median age was 55.4 years and 50.6 per cent were male. Median Breslow thickness was 1.1 mm (range 0.5-2.0 mm) and 1.1 per cent were ulcerated. Primary tumor site was 49 per cent extremities, 39 per cent trunk, and 12 per cent head/neck. Median follow-up was 68.6 months. Five-year recurrence-free, disease-specific, and overall survivals were 89, 95, and 88 per cent, respectively. During surveillance, 10 patients had concerning symptoms or physical findings prompting subsequent workup, all of which were negative for recurrence/metastases. There were only three true melanoma recurrences; all were distant metastases and presented symptomatically between scheduled follow-up visits. In light of the excellent prognosis for pathologic (SLNB negative) stage IB melanoma, an "abbreviated" cancer surveillance schedule based on conditional survival would reduce both direct and indirect costs in this cohort. The few recurrences were symptomatic and unlikely to have changed with more intensive surveillance. PMID- 29183529 TI - Efficiency and Safety of One-Step Procedure Combined Laparoscopic Cholecystectomy and Eretrograde Cholangiopancreatography for Treatment of Cholecysto Choledocholithiasis: A Randomized Controlled Trial. AB - We aimed to evaluate the efficiency and safety of one-step procedure combined endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC) for treatment of patients with cholecysto choledocholithiasis. A prospective randomized study was performed on 63 consecutive cholecysto-choledocholithiasis patients during 2008 and 2011. The efficiency and safety of one-step procedure was assessed by comparing the two step LC with ERCP + endoscopic sphincterotomy (EST). Outcomes including intraoperative features, postoperative features (length of stay and postoperative complications) were evaluated. One- or two-step procedure of LC with ERCP + EST was successfully performed in all patients, and common bile duct stones were completely removed. Statistical analyses showed that length of stay and pulmonary infection rate were significantly lower in the test group compared with that in the control group (P < 0.05), whereas no statistical difference in other outcomes was found between the two groups (all P > 0.05). The one-step procedure of LC with ERCP + EST is superior to the two-step procedure for treatment of patients with cholecysto-choledocholithiasis regarding to the reduced hospital stay and inhibited occurrence of pulmonary infections. Compared with two-step procedure, one-step procedure of LC with ERCP + EST may be a superior option for cholecysto choledocholithiasis patients treatment regarding to hospital stay and pulmonary infections.

PMID- 29183531 TI - Patterns of Recurrence and Mechanisms of Failure after Open Ventral Hernia Repair with Mesh. AB - Recurrence after ventral hernia repair (VHR) remains a significant complication. We sought to identify the technical aspects of VHR associated with recurrence. Patients who underwent open midline VHR between 2006 and 2013 (n = 261) were retrospectively evaluated. Patients with recurrence (Group 1, n = 48) were compared with those without recurrence (Group 2, n = 213). Smoking, diabetes, and body mass index were not different between groups. More patients in Group 1 underwent clean-contaminated, contaminated, or dirty procedures (43.8 vs 27.7%; P = 0.021). Group 1 had a higher incidence of surgical site occurrence (52.1 vs 32.9%; P = 0.020) and surgical site infection (43.8 vs 15.5%; P < 0.001). Recurrences were due to central mesh failure (CMF) (39.6%), midline recurrence after biologic or bioabsorbable mesh repair (18.8%), superior midline (16.7%), lateral (16.7%), and after mesh explantation (12.5%). Most CMF (78.9%) occurred with light-weight polypropylene (LWPP). Recurrence was higher if the midline fascia was unable to be closed. Recurrence with midweight polypropylene (MWPP) was lower than biologic (P < 0.001), bioabsorbable (P = 0.006), and light-weight polypropylene (P = 0.046) mesh. Fixation, component separation technique, and mesh position were not different between groups. Wound complications are associated with subsequent recurrence, whereas midweight polypropylene is associated with a lower overall risk of recurrence and, specifically, CMF. PMID- 29183532 TI - Descriptive Analysis of Venous Thromboembolism in Georgia Trauma Centers Compared with National Trauma Centers Participating in the Trauma Quality Improvement Program. AB - This study was designed to compare the incidence of venous thromboembolism (VTE) in Georgia trauma centers with other national trauma centers participating in the Trauma Quality Improvement Program (TQIP). The use of chemoprophylaxis and characteristics of patients who developed VTE were also examined. We conducted a retrospective observational study of 325,703 trauma admissions to 245 trauma centers from 2013 to 2014. Patient demographics, rate of VTE, as well as the use, type, and timing of chemoprophylaxis were compared between patients admitted to Georgia and non-Georgia trauma centers. The rate of VTE in Georgia trauma centers was 1.9 per cent compared with 2.1 per cent in other national trauma centers. Overall, 49.6 per cent of Georgia patients and 45.5 per cent of patients in other trauma centers had documented chemoprophylaxis. Low molecular weight heparin was the most commonly used medication. Most patients who developed VTE did so despite receiving prophylaxis. The rate of VTE despite prophylaxis was 3.2 per cent in Georgia and 3.1 per cent in non-Georgia trauma centers. Mortality associated with VTE was higher in Georgia trauma centers compared with national TQIP benchmarks. The incidence of VTE and use of chemoprophylaxis within Georgia trauma centers were similar to national TQIP data. Interestingly, most patients who developed VTE in both populations received VTE prophylaxis. Further research is needed to develop best-practice guidelines for prevention, early detection, and treatment in high-risk populations. PMID- 29183533 TI - Predictive Factors for Treatment Failure after Peritoneovenous Shunt for Hepatic Ascites. AB - Peritoneovenous shunt (PVS) is used to treat refractory ascites. Here, we identify predictive factors for inhospital death after PVS placement. Thirty-five patients with refractory ascites related to liver cirrhosis and/or hepatocellular carcinoma (HCC) who underwent PVS placement between February 2005 and February 2013 were included in the study. Group A comprised 13 patients for whom the PVS placement outcome was inhospital death. Group B comprised 22 patients who were discharged after PVS placement without complications. Patient background and laboratory data were analyzed to identify risk factors for inhospital death. HCC prevalence in Groups A and B was 92 and 55 per cent, respectively (P = 0.02) and that of portal venous tumor thrombus (PVTT) was 54 and 9 per cent, respectively (P = 0.003). The mean des-gamma-carboxy prothrombin (DCP) level in both groups was 15,553 +/- 49,330 and 787 +/- 2600 mAU/mL, respectively (P = 0.009). Multivariate analysis revealed that the presence of PVTT was the only independent predictor of inhospital death (P = 0.007). The presence of PVTT, HCC, and elevated des-gamma-carboxy prothrombin levels are predictors of inhospital death after PVS placement. Therefore, PVS should not be used to treat refractory ascites in patients with these predictors, particularly with PVTT. PMID- 29183534 TI - Papillary Breast Lesions: Association with Malignancy and Upgrade Rates on Surgical Excision. AB - Intraductal papilloma falls under the category of benign breast mass. However, recent studies show that it can harbor occult carcinoma. The management of benign intraductal papilloma remains controversial because of its nonspecific radiologic and histological findings, as well as its association with surrounding malignant pathology. The purpose of this study is to investigate upgrade rates of a benign intraductal papilloma on surgical excision and the need for surgical excision of papillary lesions diagnosed at core needle biopsy. A retrospective review of a single institution's pathology database between 2011 and 2015 identified 43 core biopsies with benign papilloma. We followed the upgrade rates of these lesions on surgical excision. There were 90 biopsies with the diagnosis of benign intraductal papilloma. The average age was 55.2 (range from 24-87 years old). Forty-three had benign intraductal papilloma; 28 of the 43 core biopsies had surgical excision. Two (7.1%) had an upgrade from benign intraductal papilloma to intraductal papilloma with atypia. One (3.6%) had an upgrade to ductal carcinoma in situ. None had invasive cancer. Surgical findings were in agreement with core biopsies in 25 (89.3%) of 28 cases (kappa = 0.80, P < 0.0001). Core biopsies have a statistically significant correlation with pathologies on surgical excision in detecting atypia in breast lesion as demonstrated by kappa = 0.80. However, the study shows benign intraductal papillomas on core biopsy have an upgrade rate of 10.7 per cent after undergoing surgical excision. As such, we recommend a more aggressive approach including surgical excision of all benign intraductal papillary lesions. PMID- 29183535 TI - Major General Malcolm C.

PMID- 29183536 TI - A Preliminary Analysis of Compassion Fatigue in a Surgeon Population: Are Female Surgeons at Heightened Risk? AB - Compassion fatigue (CF), a state of physical/emotional distress caused by repeatedly caring for those experiencing traumatic episodes, is a prevalent issue for today's healthcare provider. We sought to characterize levels of CF within a surgeon population, particularly comparing trauma surgery with other surgical specialties. A survey containing the Professional Quality of Life Scale (ProQOL), a validated tool assessing compassion satisfaction (CS), CF, and burnout (BO) was distributed via electronic newsletter to members of the American College of Surgeons. Demographic data and Professional Quality of Life Scale scores for CS, BO, and CF were collected and compared within specialty and gender subgroups. A total of 178 surgeons completed surveys. Respondents were predominantly male, general surgeons, >55 years old. Trauma surgeons composed the second largest subgroup. Levels of CS were significantly lower in the trauma surgeon subgroup compared to other surgical specialties (trauma: 37.1 +/- 5.28, other: 39.5 +/- 6.30; P = 0.044). Female surgeons from all specialties exhibited significantly higher levels of BO (female: 26.7 +/- 6.10, male: 24.6 +/- 6.79; P = 0.035) and CF (female: 24.2 +/- 6.29, male: 21.9 +/- 6.11; P = 0.021) compared with male surgeons. Subanalyses comparing female trauma surgeons to female surgeons in other specialties found female trauma surgeons exhibited significantly lower levels of CS (trauma: 34.8 +/- 4.63, other: 38.8 +/- 5.99; P = 0.038) and higher levels of BO (trauma: 29.1 +/- 3.14, other: 25.3 +/- 6.41; P = 0.049). Trauma surgeons, particularly female trauma surgeons, may be at a heightened risk for developing a poorer overall professional quality of life compared with surgeons of other specialties. In addition, female surgeons may be at greater risk for developing CF compared with male counterparts. PMID- 29183537 TI - Continuing Trauma: The Unmet Needs of Trauma Patients in the Postacute Care Setting. AB - Trauma care has traditionally focused on prehospital and hospital settings, yet many injured patients report emotional distress in the postacute care setting, which is known to impair recovery. The objective of this study was to assess postdischarge emotional recovery and communication preferences. An observational cohort of 100 adult patients from our Level 1 Trauma Center was surveyed one to two months postdischarge. Among those employed preinjury, 44 per cent had not returned to work. Nearly half screened positive for emotional issues (posttraumatic stress disorder, depression, and/or psychological distress); of these, only 35 per cent considered getting professional help and only 10 per cent received help. The barrier most cited (58%) was cost; 42 per cent did not know how or where to get help. Most participants responded "no" or "I don't know" when asked if they had received information about coping with negative emotions after injury and how to seek help from a doctor to address these emotions. Two-thirds preferred to receive such information via phone call from a health care provider or by text. Eighty-nine per cent owned a cellphone. Our trauma systems are failing to provide comprehensive care or look at the ultimate outcomes of our patients, yet modern technology could provide needed resources to patients in novel ways. PMID- 29183538 TI - Laparoscopic Hyperthermic Intraperitoneal Chemotherapy for Peritoneal Carcinomatosisfrom Gastric Cancer: Its Beneficial Effects on Reduction and Exact Evaluation of the Peritoneal Cancer Index. AB - We assessed whether the laparoscopic hyperthermic intraperitoneal chemotherapy (L HIPEC) + neoadjuvant intraperitoneal and systemic chemotherapy (NIPS) could reduce the peritoneal cancer index (PCI; which is defined by Sugerbaker) and improve the possibility to obtain a complete cytoreductive surgery (CRS with peritonectomy; basically according to the Sugerbaker's procedure). After L-HIPEC + NIPS, the PCI score was decreased in 89.5 per cent of patients, and the average score was significantly reduced. The average PCI reduction of improved PCI cases was 10.2 +/- 8.4. The hypothetical cut-off was at a PCI score of six with significant higher possibility of CRS completeness. Twelve patients had high-PCI (PCI > 6), and six of them (50.0%) were converted to low-PCI (PCI ? 6) and got a complete CRS. There was a significant relationship between post-PCI (PCI after L HIPEC + NIPS) and CRS completeness; however, pre-PCI (PCI before L-HIPEC + NIPS) value was not a relevant factor. The high-PCI and increased PCI even after L HIPEC + NIPS (deteriorated-PCI) were suggested as important risk factors for surgical completeness. Neither pre- nor postcytological results had a significant relationship between CRS completeness. However, the deteriorated cytological class was considered as a risk factor for CRS completeness. The second-look laparoscopy would be recommended for the better selection of the patients who can receive benefits by this extensive surgery.

AB - In 2002, the internet based reporting system OSIRIS was introduced in the Netherlands and by the end of that year had fully replaced the paper-based reporting system. The objectives of OSIRIS were to improve timeliness and completeness of surveillance data on infectious diseases reported from regional to national level. We compared the timeliness of infectious diseases reported by the conventional paper-based system in 2001 with those reported by OSIRIS in 2003. Two distinct types of delay were compared: total delay: defined as time between sympton onset and reporting at national level and central delay: defined as time between regional and national reporting. Median delays between both systems were compared using the Wilcoxon Rank Sum-Test. We also compared electronic reports received via OSIRIS in 2003 to those received through the conventional system for 2001 for completeness of specific data fields. The Fisher exact test and the Mantel-Haenzel test with Yates correction were used to determine the significance of proportions of completed data fields in each system.

AB - Analysis of methicillin-resistant Staphylococcus aureus (MRSA) isolates in the Netherlands in 2003 revealed that 8% of the hospital isolates carried the loci for Panton-Valentine leukocidin (PVL). Molecular subtyping showed that most Dutch PVL-MRSA genotypes corresponded to well-documented global epidemic types. The most common PVL-MRSA genotypes were sequence type ST8, ST22, ST30, ST59 and ST80. MRSA with ST8 increased in the Netherlands from 1% in 2002 to 17% in 2003. It is emphasised that PVL-MRSA might not only emerge in the community, but also in the hospital environment.

We performed a descriptive epidemiological study of TB in two St Petersburg remand prisons (SIZOs). The medical databases of the TB divisions in these prisons were searched for all diagnosed cases of TB from 1 January 2000 to 31 December 2002. The main diagnostic method was chest x ray. The total number of reported TB cases in these two remand prisons during this three-year period was 876. Out of these, 432 were diagnosed at entry to prison, and 444 developed the disease during incarceration, with the proportion diagnosed during incarceration increasing over time. The majority of cases were aged under 30 years. TB incidence in Russian remand prisons is still very high and needs to be monitored closely. PMID- 29183542 TI - Acute hepatitis C infection in HIV positive men who have sex with men in Paris, France, 2001-2004. AB - In mid-2004, three Parisian hospital wards informed the Institut de veille sanitaire of recent acute hepatitis C in HIV-infected (HIV+) men who had sex with men (MSM). These cases for whom none of the usual bloodborne routes for hepatitis C (HCV) transmission was found, reported having had unprotected sex. In October 2004, we conducted a retrospective investigation in Parisian hospital wards to explore HCV modes of transmission in recent acute hepatitis C in HIV+ MSM. Patient demographics, clinical and biological status of HIV infection, reasons for HCV testing, sexual behaviour and risk factors for HCV transmission within the 6 months before hepatitis onset were collected from medical records. An anonymous self-administered questionnaire on sexual behaviour within the six months before hepatitis onset was also offered to all cases. We identified 29 cases of acute hepatitis C in HIV+ MSM with onset from April 2001 to October 2004. HIV infection was asymptomatic for 76%. Median age at hepatitis C onset was 40 (28-54) years. In all records, were noted unprotected anal sex, fisting in 21% and a concomitant sexually transmitted infection (STI) in 41%. Median time between HIV diagnosis and HCV infection was 6.5 years (0-22). From the 11 self administered questionnaires completed, 10 reported an STI, 8 "hard" sexual practices, 6 bleeding during sex and 5 fisting. HCV transmission probably occurred through bleeding during unprotected traumatic anal sex among HIV+ MSM and may be facilitated by STI mucosal lesions. This report stresses the continuous need to strongly advocate safer sex to MSM.

AB - Several new tests have been recently introduced by the United Kingdom Blood Services to improve safety. The frequency (or risk) of hepatitis B virus (HBV), hepatitis C virus (HCV) and HIV infectious donations entering the UK blood supply during 1996-2003 has been estimated. These years span the introduction of nucleic acid testing (NAT) for HCV, HIV combination antigen and antibody test and NAT for HIV. The frequency of an infectious donation entering the blood supply due to i) the window period, ii) assay failures and iii) human and technical errors in testing and processing, was estimated. The window period risk was estimated using the incidence of infection in donors and the length of the window period for tests in use, with an adjustment for atypical inter-donation intervals in seroconverting donors. The estimated frequency of infectious donations entering the blood supply during 1996-2003 was 1.66, 0.80 and 0.14 per million for HBV, HCV and HIV respectively. HCV NAT resulted in an over 95% fall in the risk of HCV. Current usage of HIV combined antibody-antigen tests and of HIV NAT reduced the estimated risk of HIV by 10%. Since 1996, the risk of transfusion-transmitted HBV, HCV and HIV infection in the UK has been lowered by several improvements to donation testing, although the absolute reduction in risk has been small. Vigilance for errors and the affects of donor selection may be as or more important than further reductions to window periods of tests for improving blood safety with respect to HBV, HCV and HIV. PMID- 29183544 TI - Bichat guidelines for the clinical management of Q fever and bioterrorism-related Q fever. AB - Q fever is a zoonotic disease caused by Coxiella burnetii. Its interest as a potential biological weapon stems from the fact that an aerosol of very few organisms could infect humans. Another route of transmission of C. burnetii could be through adding it to the food supply. Nevertheless, C. burnetii is considered to be one of the less suitable candidate agents for use in a bioterrorist attack; the incubation is long, many infections are inapparent and the mortality is low. In the case of an intentional release of C. burnetii by a terrorist, clinical presentation would be similar to naturally occurring disease. It may be asymptomatic, acute, normally accompanied by pneumonia or hepatitis, or chronic, usually manifested as endocarditis. Most cases of acute Q fever are asymptomatic and resolve spontaneously without specific treatment. Nevertheless, treatment can shorten the duration of illness and decrease the risk of complications such as endocarditis. Post-exposure prophylaxis is recommended after the exposure in the case of a bioterrorist attack. PMID- 29183545 TI - Bichat guidelines for the clinical management of viral encephalitis and bioterrorism-related viral encephalitis. AB - Most of the viruses involved in causing encephalitis are arthropod-borne viruses, with the exception of arenaviruses that are rodent-borne. Even if little information is available, there are indications that, most of these encephalitis associated viruses could be used by aerosolisation during a bioterrorist attack. Viral transfer from blood to the CNS through the olfactory tract has been suggested. Another possible route of contamination is by vector-borne transmission such as infected mosquitoes or ticks. Alphaviruses are the most likely candidates for weaponisation. The clinical course of the diseases caused by these viruses is usually not specific, but differentiation is possible by using an adequate diagnostic tool. There is no effective drug therapy for the treatment of these diseases and treatment is mainly supportive, but vaccines protecting against some of these viruses do exist. PMID- 29183546 TI - Surveillance of antimicrobial resistance in Bulgaria - a synopsis from BulSTAR 2003. AB - We introduce Bulgarian Surveillance Tracking Antimicrobial Resistance (BulSTAR) and make the first report on surveillance data for 2003. This longitudinal surveillance programme monitors the isolation and antimicrobial susceptibility of all clinically significant microorganisms isolated from blood cultures, cerebrospinal fluid, upper and lower respiratory tract, urine and wound samples in the participating microbiology laboratories. Twenty eight public, 45 hospital and 6 private laboratories from all 28 counties of the Republic of Bulgaria participated in BulSTAR 2003. The total number of isolates from monitored sources during the surveillance period was 98 929. Seven microorganisms represented 72% of all isolated bacteria in BulSTAR 2003: Escherichia coli, Staphylococcus aureus, Proteus-Providencia-Morganella group, Klebsiella spp., Pseudomonas spp, Streptococcus pneumoniae and Streptococcus pyogenes. Generally the resistance of clinically significant Gram positive and Gram negative bacteria in Bulgaria was estimated to be at a medium level when compared with many other surveillance sources worldwide. A unique 32-year experiment on the population by treating all severe infections with an ampicillin/gentamicin combination resulted in twofold higher levels of resistance to amynoglycosides compared with other countries worldwide. This is due to the extremely conservative treatment schemes used in the former socialist countries, based on national directives and cheap domestic production of gentamicin and ampicillin. The forthcoming introduction of a computer network and improvements in detecting mistakes are expected to increase the sensitivity and the significance of BulSTAR surveillance system - an indispensable tool in the combat against increasing worldwide antibiotic resistance. PMID- 29183548 TI - Travellers returning to Sweden as sentinels for comparative disease incidence in other European countries, campylobacter and giardia infection as examples. AB - Comparable figures on disease incidence between countries are difficult to attain. We therefore compared risk of infection for Swedes going to other European countries. We took as the numerator the number of imported cases from European countries of campylobacter and giardia infection in the national Swedish surveillance database, and as the denominator, the number of visitors to each country from a commercial database on foreign travel. Risk of infection in tourists was also compared to national incidence figures for a selection of countries. PMID- 29183549 TI - Communicable disease control in a migrant seasonal workers population: A case study in Norway. AB - Reliable data on the health status of migrant seasonal workers in Europe is scarce. Access to public health care for this population depends on national regulations, and their legal status in host countries. In this manuscript we describe a case study of a salmonellosis outbreak that occurred in Norway, and highlight the difficulties encountered in applying control measures in a population of seasonal migrant farm workers. Surveillance and control of infectious diseases need to be supported by legislation which makes implementation of control measures possible. Efforts have been made to improve the rights for migrants in Europe with regard to healthcare, but seasonal migrant workers still remain largely outsiders where these measures are concerned. Special attention should be given to this disadvantaged group in terms of social rights and healthcare. Preparedness plans should be improved to deal with contagious pathogens involving the seasonal migrant population. PMID- 29183550 TI - Prevention of congenital rubella infection: a challenge for every country in Europe. AB - The current issue of Eurosurveillance provides the common theme of the epidemiology and control of congenital rubella infection (CRI) across Europe. It provides a stark reminder that despite the availability of a safe and effective vaccine for many years, CRI - the consequence of rubella infection during pregnancy, remains an important public health problem both in the European Union and the wider WHO European Region. The following articles outline the various operational challenges facing national immunisation programmes in Europe. They vividly illustrate large differences in disease burden and inequalities in access to preventive health services both between and within countries. Four groups of countries can be distinguished. PMID- 29183551 TI - Preliminary results from the new HIV surveillance system in France. AB - In addition to AIDS surveillance, data on HIV infection are necessary to better follow the dynamics of the epidemic. We report the first results of France's mandatory anonymous HIV notification system, which is linked to a virological surveillance of recent HIV infections and of circulating HIV types, groups and subtypes. HIV notifications are initiated by microbiologists who create an anonymous code of patient's identity. Clinicians complete the notification form with epidemiological and clinical data. Notifications are sent to the local health authorities and passed to the Institut de Veille Sanitaire (InVS). PMID- 29183552 TI - Detection of adamantane-sensitive influenza A(H3N2) viruses in Australia, 2017: a cause for hope? AB - For over a decade virtually all A(H3N2) influenza viruses have been resistant to the adamantane class of antivirals. However, during the 2017 influenza season in Australia, 15/461 (3.3%) adamantane-sensitive A(H3N2) viruses encoding serine at residue 31 of the M2 protein were detected, more than the total number identified globally during the last 6 years. A return to wide circulation of adamantane sensitive A(H3N2) viruses would revive the option of using these drugs for treatment and prophylaxis. PMID- 29183553 TI - Childhood multidrug-resistant tuberculosis in the European Union and European Economic Area: an analysis of tuberculosis surveillance data from 2007 to 2015. AB - BackgroundConfirming tuberculosis (TB) in children and obtaining information on drug susceptibility is essential to ensure adequate treatment. We assessed whether there are gaps in diagnosis and treatment of multidrug-resistant (MDR) TB in children in the European Union and European Economic Area (EU/EEA), quantified the burden of MDR TB in children and characterised cases. Methods: We analysed surveillance data from 2007 to 2015 for paediatric cases younger than 15 years. Results: In that period, 26 EU/EEA countries reported 18,826 paediatric TB cases of whom 4,129 (21.9%) were laboratory-confirmed. Drug susceptibility testing results were available for 3,378 (17.9%), representing 81.8% of the confirmed cases. The majority (n = 2,967; 87.8%) had drug-sensitive TB, 249 (7.4%) mono resistant TB, 64 (1.9%) poly-resistant TB, 90 (2.7%) MDR TB and eight (0.2%) had extensively drug-resistant (XDR) TB. MDR TB was more frequently reported among paediatric cases with foreign background (adjusted odds ratio (aOR) = 1.73; 95% confidence interval (95% CI): 1.12-2.67) or previous TB treatment (aOR: 6.42; 95% CI: 3.24-12.75). Successful treatment outcome was reported for 58 of 74 paediatric MDR TB cases with outcome reported from 2007 to 2013; only the group of 5-9 years-olds was significantly associated with unsuccessful treatment outcome (crude odds ratio (cOR) = 11.45; 95% CI: 1.24-106.04). Conclusions: The burden of MDR TB in children in the EU/EEA appears low, but may be underestimated owing to challenges in laboratory confirmation. Diagnostic improvements are needed for early detection and adequate treatment of MDR TB. Children previously treated for TB or of foreign origin may warrant higher attention. PMID- 29183554 TI - Molecular characterisation of human Shiga toxin-producing Escherichia coli O26 strains: results of an outbreak investigation, Romania, February to August 2016. AB - IntroductionAt the beginning of 2016, an increase in paediatric haemolytic uremic syndrome (HUS) cases was observed in Romania. The microbiological investigations allowed isolation of Shiga toxin-producing Escherichia coli (STEC) O26 as the causative agent from most cases. Methods: An enhanced national surveillance of HUS and severe diarrhoea was established across the country following the identification of the first cases and was carried out until August 2016. A total of 15 strains were isolated from 10 HUS and five diarrhoea cases. Strains were characterised by virulence markers (i.e. stx type/subtype, eae, ehxA genes), phylogroup, genetic relatedness and clonality using PCR-based assays, PFGE and multilocus sequence typing (MLST). The first six strains were further characterised by whole genome sequencing (WGS). Results: Five PCR-defined genotypes were distinguished. All strains from HUS cases harboured stx2a and eae, with or without stx1a, while strains from diarrhoea cases carried exclusively stx1a and eae genes. PFGE resolved strains into multiple pulsotypes, compatible with a certain geographic segregation of the cases, and strains were assigned to phylogroup B1 and sequence type (ST) 21. WGS confirmed the results of conventional molecular methods, brought evidence of O26:H11 serotype, and complemented the virulence profiles. Discussion/conclusion: This first description of STEC O26 strains from cases in Romania showed that the isolates belonged to a diverse population. The virulence content of most strains highlighted a high risk for severe outcome in infected patients. Improving the national surveillance strategy for STEC infections in Romania needs to be further considered. PMID- 29183556 TI - Syphilis surveillance and trends of the syphilis epidemic in Germany since the mid-90s. AB - Recent surveillance reports from Europe and the United States show an increase in syphilis cases. Accurate epidemiological information about the distribution of syphilis is important for targeting screening and intervention programmes. The German syphilis notification system changed in 2001 from physician to laboratory based reporting, which is complemented by a newly introduced sexually transmitted infection (STI) sentinel system. After reaching an all time low during the 1990s, syphilis notifications have increased significantly since 2001, coinciding with the introduction of the new reporting system. However, the increased reported incidence is reflecting a true rise in the number of cases and is not predominantly determined by more underreporting through the previous reporting system. The increase reflects syphilis outbreaks among men who have sex with men (MSM). The first of these outbreaks was observed in Hamburg in 1997. In 2003, incidence in men was ten times higher than in women. An estimated 75% of syphilis cases are currently diagnosed among MSM. A high proportion (according to sentinel data, up to 50%) of MSM diagnosed with syphilis are HIV positive. The continuously high number of syphilis cases diagnosed among heterosexuals in Germany in recent years compared with other western European countries may reflect the higher population movement between Germany and syphilis high incidence regions in south-east and eastern Europe. PMID- 29183557 TI - Occurrence of Salmonella Enteritidis phage type 29 in Austria : an opportunity to assess the relevance of chicken meat as source of human salmonella infections. AB - Assuming that the various phage types of Salmonella Enteritidis (S. Enteritidis) are largely equally virulent, the importance of certain foods as sources of infection for human salmonellosis can be deduced from differences in the distribution of phage types in human and non-human samples. In 2002, S. Enteritidis phage type 29 (PT29) was first isolated from non-human test samples in Austria. S. Enteritidis PT29 accounted for 44 (27.7%) of 159 S. Enteritidis strains, derived from veterinary samples of chicken (e.g. meat, giblets) or chicken habitations (e.g. swabs from the coop and excrement). At the food retail level (chicken meat, chicken liver), five (13.1%) of 38 S. Enteritidis isolates were PT29. The proportion of S. Enteritidis PT29 in human samples was much lower. Only 0.4% (30 human primary isolates) of all S. Enteritidis isolates in the year 2002, and 0.33% (23 human primary isolates) of all human S. Enteritidis strains in 2003 were PT29. In our opinion, the discrepancy between the high prevalence of S. Enteritidis PT29 in broilers and chicken meat and the low number of PT29 cases in humans indicates that chicken meat of Austrian origin is currently only a minor source of human S. Enteritidis infections. PMID- 29183555 TI - Enhanced Bordetella pertussis acquisition rate in adolescents during the 2012 epidemic in the Netherlands and evidence for prolonged antibody persistence after infection. AB - IntroductionIn 2012 a large epidemic of pertussis occurred in the Netherlands. We assessed pertussis toxin (PT) antibody levels in longitudinal serum samples from Dutch 10-18 year-olds, encompassing the epidemic, to investigate pertussis infection incidence. Methods: Blood was sampled in October 2011 (n = 239 adolescents), then 1 year (2012; n = 228) and 3 years (2014; n = 167) later. PT IgG concentrations were measured by immunoassay and concentrations >=50 IU/mL (seropositive) assumed indicative of an infection within the preceding year. Results: During the 2012 epidemic, 10% of participants became seropositive, while this was just 3% after the epidemic. The pertussis acquisition rate proved to be sixfold higher during the epidemic (97 per 1,000 person-years) compared with 2012 2014 (16 per 1,000 person-years). In 2012, pertussis notifications among adolescents nationwide were 228/100,000 (0.23%), which is at least 40 times lower than the seropositivity percentage. Remarkably, 17 of the 22 seropositive participants in 2011, were still seropositive in 2012 and nine remained seropositive for at least 3 years. Discussion: Longitudinal studies allow a better estimation of pertussis infections in the population. A PT-IgG concentration >=50 IU/mL as indication of recent infection may overestimate these numbers in cross-sectional serosurveillance and should be used carefully. PMID- 29183558 TI - The incidence of S. aureus bacteraemia in acute hospitals of the Mid-Western Area, Ireland, 2002-2004. AB - Concerns about healthcare-associated infections and the global crisis in antimicrobial resistance has combined to accentuate the fears around so-called "superbugs". In Ireland there is no single agreed indicator regarded as a true measure of the level of methicillin resistant Staphylococcus aureus (MRSA) in hospitals. The objective of this study was to compare two crude measures of MRSA the percentage of bacteraemia caused by MRSA and the incidence rate (per 1000 bed days used) of MRSA bacteraemia in six acute hospitals. We examined all blood cultures positive for S. aureus (methicillin sensitive and resistant) from 2002 to 2004 in the Health Service Executive (HSE) Mid-Western Area of Ireland. Hospital In-Patient Enquiry (HIPE) data was used to determine monthly in-patient bed days used. Of 245 patient episodes of bacteraemia, 119 were MRSA. The trends in the percentage of isolates that were MRSA and the incidence rate calculated were compared. The incidence rate appears to be a more reliable and robust indicator of MRSA in hospitals than the percentage. Despite many difficulties in interpreting indicators of MRSA they should not preclude the regular publication of data at least at regional level in Ireland. PMID- 29183559 TI - Hospital preparedness and management of patients affected by viral haemorrhagic fever or smallpox at the Lazzaro Spallanzani Institute, Italy. AB - The US cases of anthrax in 2001 and the recent severe acute respiratory syndrome outbreak have heightened the need for preparedness and response to naturally emerging and re-emerging infections or deliberately released biological agents. This report describes the response model of the Istituto Nazionale per le Malattie Infettive Lazzaro Spallanzani (INMI), Rome, Italy for managing patients suspected of or affected by smallpox or viral haemorrhagic fever (VHF) either in the context of an intentional release or natural occurrence. The INMI is Italy's leading hospital in its preparedness and response plan to bioterrorism-related infectious agents. All single and double rooms of INMI are equipped with negative air pressure, sealed doors, high efficiency particulate air (HEPA) filters and a fully-equipped anteroom; moreover, a dedicated high isolation unit with a laboratory next door for the initial diagnostic assays is available for admission of sporadic patients requiring high isolation. For patient transportation, two fully equipped ambulances and two stretcher isolators with a negative pressure section are available. Biomolecular and traditional diagnostic assays are currently performed in the biosafety level 3/4 (BSL 3/4) laboratories. Continuing education and training of hospital staff, consistent application of infection control practices, and availability of adequate personnel protective equipment are additional resources implemented for the care of highly infectious patients and to maintain the readiness of an appropriately trained workforce to handle large scale outbreaks. PMID- 29183560 TI - Syphilis surveillance and epidemiology in the United Kingdom. AB - The aim of this article is to describe trends in infectious syphilis in the UK, and specifically the epidemiology of the London syphilis outbreak, the largest in the UK to date. Analysis of routine surveillance data from genitourinary medicine (GUM) clinics was performed as well as data collection through enhanced surveillance systems. There have been substantial increases in diagnoses of infectious syphilis between 1998 and 2003, with a 25-fold increase seen in men who have sex with men (MSM) (from 43 to 1028 diagnoses); 6-fold (138 to 860) in heterosexual men and 3-fold (112 to 338) in women. The national rise in syphilis was driven by a series of local outbreaks, the first of which occurred in 1997. To date, 1910 cases have been reported in the London outbreak, first detected in April 2001. High rates of HIV co-infection were seen among MSM, with MSM likely to be of white ethnicity and born in the UK. In contrast, heterosexuals were more likely to be of black ethnicity and born outside the UK. Most syphilis infections were acquired in London. MSM bear the brunt of the national resurgence in infectious syphilis. Substantial rises in male heterosexual cases has resulted in a divergence between male heterosexual and female cases, which now requires further investigation. PMID- 29183561 TI - Human immunodeficiency virus, hepatitis C and hepatitis B infections among blood donors in Germany 2000-2002: risk of virus transmission and the impact of nucleic acid amplification testing. AB - Blood and plasma donations in Germany are collected by several institutions, namely the German Red Cross, community and hospital-based blood services, private blood centres, commercial plasma donation sites and transfusion services of the army. All blood donation centres are required to report quarterly data on infection markers to the Robert Koch Institute, thus providing current and accurate epidemiological data. The prevalence and incidence of relevant viral infections are low in the blood donor population in Germany, with a decreasing trend for hepatitis C infections in new and repeat donors since 1997. The implementation of mandatory nucleic acid amplification technique (NAT) testing for hepatitis C virus (HCV) in 1999 has markedly improved transfusion safety. HIV NAT became mandatory in 2004 but was done voluntarily by the majority of the blood donation services before then. The potential benefit of hepatitis B virus (HBV) minipool NAT is not as clear because chronic HBV carriers with very low virus levels might donate unidentified. The residual risk of an infectious window period donation inadvertently entering the blood supply can be estimated using a mathematic model which multiplies the incidence rate by the number of days during which an infection may be present but not detectable, i.e. the length of the window period. The risk of an undetected infection without NAT testing was estimated to be 1 in 2 770 000 for HIV, 1 in 670 000 for HCV and 1 in 230 000 for HBV in 2001/2002. This contrasts with 1 in 5 540 000 for HIV, 1 in 4 400 000 for HCV and 1 in 620 000 for HBV with minipool NAT testing. This demonstrates that NAT testing can further reduce the already very small risk of infectious donations entering the blood supply. PMID- 29183562 TI - High sensitivity for tuberculosis in a national integrated surveillance system in Finland. AB - Little is known about the sensitivity of surveillance for tuberculosis after integration of formerly dedicated tuberculosis surveillance and control into the general health care system, an integration which took place in Finland in 1987. We compared routine laboratory notifications to the National Infectious Disease Register (NIDR) for Mycobacterium tuberculosis from January 1, 1995, to December 31, 1996, with data collected independently from all laboratories offering M. tuberculosis culture, and with data from patient records. 1059 culture-positive cases were found. The overall sensitivity of the NIDR was 93 % (984/1059). The positive predictive value of a culture-positive case in the NIDR to be a true culture-confirmed case was 99%. For the culture-confirmed cases in the NIDR, one or more physician notification forms had been submitted for 89%. A highly sensitive notification system for culture-positive tuberculosis can be achieved in an integrated national infectious disease surveillance system based on laboratory notification. PMID- 29183563 TI - A systematic review and economic evaluation of adalimumab and dexamethasone for treating non-infectious intermediate uveitis, posterior uveitis or panuveitis in adults. AB - BACKGROUND: Non-infectious intermediate uveitis, posterior uveitis and panuveitis are a heterogeneous group of inflammatory eye disorders. Management includes local and systemic corticosteroids, immunosuppressants and biological drugs. OBJECTIVES: To evaluate the clinical effectiveness and cost-effectiveness of subcutaneous adalimumab (Humira(r); AbbVie Ltd, Maidenhead, UK) and a dexamethasone intravitreal implant (Ozurdex(r); Allergan Ltd, Marlow, UK) in adults with non-infectious intermediate uveitis, posterior uveitis or panuveitis. DATA SOURCES: Electronic databases and clinical trials registries including MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects and the World Health Organization's International Clinical Trials Registry Platform were searched to June 2016, with an update search carried out in October 2016. REVIEW METHODS: Review methods followed published guidelines. A Markov model was developed to assess the cost-effectiveness of dexamethasone and adalimumab, each compared with current practice, from a NHS and Personal Social Services (PSS) perspective over a lifetime horizon, parameterised with published evidence. Costs and benefits were discounted at 3.5%. Substantial sensitivity analyses were undertaken. RESULTS: Of the 134 full-text articles screened, three studies (four articles) were included in the clinical effectiveness review. Two randomised controlled trials (RCTs) [VISUAL I (active uveitis) and VISUAL II (inactive uveitis)] compared adalimumab with placebo, with limited standard care also provided in both arms. Time to treatment failure (reduced visual acuity, intraocular inflammation, new vascular lesions) was longer in the adalimumab group than in the placebo group, with a hazard ratio of 0.50 [95% confidence interval (CI) 0.36 to 0.70; p < 0.001] in the VISUAL I trial and 0.57 (95% CI 0.39 to 0.84; p = 0.004) in the VISUAL II trial. The adalimumab group showed a significantly greater improvement than the placebo group in the 25 item Visual Function Questionnaire (VFQ-25) composite score in the VISUAL I trial (mean difference 4.20; p = 0.010) but not the VISUAL II trial (mean difference 2.12; p = 0.16). Some systemic adverse effects occurred more frequently with adalimumab than with placebo. One RCT [HURON (active uveitis)] compared a single 0.7-mg dexamethasone implant against a sham procedure, with limited standard care also provided in both arms. Dexamethasone provided significant benefits over the sham procedure at 8 and 26 weeks in the percentage of patients with a vitreous haze score of zero (p < 0.014), the mean best corrected visual acuity improvement (p <= 0.002) and the percentage of patients with a >= 5-point improvement in VFQ 25 score (p < 0.05). Raised intraocular pressure and cataracts occurred more frequently with dexamethasone than with the sham procedure. The incremental cost effectiveness ratio (ICER) for one dexamethasone implant in one eye for a combination of patients with unilateral and bilateral uveitis compared with limited current practice, as per the HURON trial, was estimated to be L19,509 per quality-adjusted life-year (QALY) gained. The ICER of adalimumab for patients with mainly bilateral uveitis compared with limited current practice, as per the VISUAL trials, was estimated to be L94,523 and L317,547 per QALY gained in active and inactive uveitis respectively. Sensitivity analyses suggested that the rate of blindness has the biggest impact on the model results. The interventions may be more cost-effective in populations in which there is a greater risk of blindness. LIMITATIONS: The clinical trials did not fully reflect clinical practice. Thirteen additional studies of clinically relevant comparator treatments were identified; however, network meta-analysis was not feasible. The model results are highly uncertain because of the limited evidence base. CONCLUSIONS: Two RCTs of systemic adalimumab and one RCT of a unilateral, single dexamethasone implant showed significant benefits over placebo or a sham procedure. The ICERs for adalimumab were estimated to be above generally accepted thresholds for cost-effectiveness. The cost-effectiveness of dexamethasone was estimated to fall below standard thresholds. However, there is substantial uncertainty around the model assumptions. In future work, primary research should compare dexamethasone and adalimumab with current treatments over the long term and in important subgroups and consider how short-term improvements relate to long-term effects on vision.

PMID- 29183564 TI - 'Lost and confused': parent representative groups' perspectives on child and family health services in Australia. AB - Consumer involvement in health care is widely accepted in policy and service delivery. Australia offers universal health services for families with children aged 0 to 5 years, provided by child and family health nurses and general practitioners. Services include, but are not limited to, monitoring and promoting child health and development, and supporting parents. This paper reports consumer representatives' perspectives on Australian parents' needs and experiences of child and family health services, identifying facilitators and barriers to service utilisation. Twenty-six representatives from consumer organisations explored families' experiences through focus groups. Qualitative data were analysed thematically. Consumer representatives identified several key implications for families using primary health services: feeling 'lost and confused' on the parenting journey; seeking continuity and partnership; feeling judged; and deciding to discontinue services. Participants highlighted accessible, timely, non-judgmental and appropriate interactions with healthcare professionals as vital to positive consumer experiences and optimal health and developmental outcomes. Representatives indicated that families value the fundamentals of well-designed health services: trust, accessibility, continuity, knowledge and approachability. However, both consumers and service providers face barriers to effective ongoing engagement in universally provided services.

AB - Sri Lankan Tamil refugees are among the largest group of refugees to resettle in Australia in the last decade. The aim of this study is to characterise the narratives of health-seeking among unwell Sri Lankan Tamil refugees in Melbourne, Victoria, Australia. Drawing on a qualitative, phenomenological perspective, we conducted in-depth interviews in Tamil and English with 12 participants who identified as being unwell for 6 months or more. Findings revealed three narratives of health-seeking: the search for the 'good life' that was lost or never experienced, seeking help from familiar channels in an unfamiliar context, and the desire for financial and occupational independence. These three narratives are undergirded by the metanarrative of a hope-filled recovery. These narratives of Tamil refugees' lived experience provide new insights into clinical care and health service delivery. PMID- 29183566 TI - Application of pressure-derived myocardial fractional flow reserve in chronic hemodialysis patients. AB - BACKGROUND: Although fractional flow reserve (FFR) measurements during coronary angiography are performed in routine clinical practice, few studies have evaluated FFR measurements in dialysis patients. METHODS: We retrospectively studied 42 hemodialysis patients with suspected or known coronary artery disease (CAD) who underwent stress myocardial perfusion imaging and coronary angiography with FFR measurements for 61 coronary lesions. The cut-off value for FFR to detect myocardial ischemia was determined by receiver operating characteristic (ROC) curve analysis. RESULTS: There were 61 coronary vessels measured by FFR. The FFR range was 0.34-0.93 with a mean of 0.74+/-0.13. The ROC curve analysis revealed that the best cut-off value of FFR for detecting myocardial ischemia was 0.76 (p<0.0001), with 70% sensitivity, 86% specificity, and 76% accuracy for myocardial ischemia. Compared with patients who had positive myocardial ischemia and an FFR<=0.76, those who had negative myocardial ischemia despite an FFR<=0.76 had less left ventricular (LV) mass index, whereas patients who had positive myocardial ischemia despite an FFR>0.76 had greater LV mass indexor serum calcium phosphorus product. CONCLUSIONS: The cut-off value of FFR for myocardial ischemia in chronic hemodialysis patients is similar to that in other CAD patients. However, caution is necessary when FFR measurements are applied to dialysis patients with significantly increased LV mass index or serum calcium-phosphorus product.

PMID- 29183568 TI - Vertical head and pelvic movement symmetry at the trot in dogs with induced supporting limb lameness. AB - Compensatory limb loading has been studied in lame dogs; however, little is known about how these compensations relate to motion of the head and pelvis, assessment of which is an important component of lameness examinations. The aim of this study was to describe the patterns of vertical head and pelvic motion symmetry at the trot in dogs with induced supporting limb lameness in the forelimbs or hind limbs. Ten sound dogs were trotted on a treadmill before and after temporary induction of moderate lameness (grade 2/5) in each limb. Reflective markers were located on the head, pelvis and right forelimb, and kinematic data were captured with a motion capture system. Upper body symmetry parameters were calculated, including differences in the highest (HDmax) and in the lowest (HDmin) positions of the head, and in the highest (PDmax) and in the lowest (PDmin) positions of the mid-pelvis, with a value of zero indicating symmetry. The head was lowered more during the sound limb stance phase and lowered less during the lame limb stance phase in supporting forelimb lameness (HDmin: 4.6mm in dogs when sound, 18.3mm when left limb lameness was induced and 20.5mm when right limb lameness was induced). The mid-pelvis was lowered more during the sound limb stance phase and lowered and lifted less during the lame limb stance phase in supporting hind limb lameness (PDmin: 1mm in dogs when sound, -10.1mm in left limb lameness and 8.4mm in right limb lameness). The hip of the lame side, measured at the level of the greater trochanter, had an increased downwards displacement during the lame limb swing phase (-21mm in left hind limb lameness, P=0.005; 23.4mm in right hind limb lameness, P=0.007). Asymmetry in the lowering of the head or mid-pelvis is a more sensitive indicator of supporting forelimb and hind limb lameness, respectively, than asymmetry in the raising of the head. Increased displacement of the hip ('hip drop' of the lame side during its swing phase) is a good indicator of hind limb lameness in dogs. PMID- 29183569 TI - Development of a fibrinolysis assay for canine plasma. AB - Unbalanced coagulation and fibrinolysis leads to hemorrhage or thrombosis. Thromboelastography has been used to characterize hypo- and hyper-fibrinolysis in dogs, however the technique requires specialized instrumentation and proprietary reagents that limit its availability. The aim of this study was to develop a simple microplate method for assessment of fibrinolysis in canine plasma. Plasma from healthy dogs was mixed in a microwell plate with tissue factor, calcium, phospholipid and tissue plasminogen activator. Light absorbance was measured at regular intervals until return to baseline. Peak optical density (milli absorption units, mAU), formation velocity (mAU/s), lysis velocity (mAU/s) and area under the curve (mAU.s) were calculated. The influence of potential interferents, variation in fibrinogen and ex vivo addition of heparin and aminocaproic acid on assay performance was determined. Inter-day coefficients of variation were <=15% for all variables. Bilirubin<=1.88mg/dL and hemoglobin<=0.09mg/dL did not interfere with assay variables. Aminocaproic acid (40MUg/mL) and heparin (0.125U/mL) caused almost complete inhibition of fibrinolysis and coagulation, respectively. All variables except lysis velocity (R2=0.08) were associated with fibrinogen concentration (R2>0.8). This assay showed acceptable performance characteristics for measurement of fibrinolysis in normal canine plasma. The assay utilizes small volume citrate plasma samples and readily available instrumentation and reagents, is not influenced by mild to moderate hemolysis or icterus and detects the presence of fibrinolysis inhibitors. PMID- 29183570 TI - Post-operative outcomes of surgical and chemical castration with zinc gluconate in dogs presenting to veterinary field clinics. AB - The objective of this study was to characterize post-operative outcomes of chemical castration as compared to surgical castration performed by existing municipal field clinics. Fifty-four healthy adult male dogs underwent chemical castration with zinc gluconate solution and 55 healthy adult male dogs underwent surgical castration in veterinary field clinics. Dogs in each group were evaluated for swelling, inflammation, and ulceration (chemical castration) or dehiscence (surgical castration) at Days 3, 7, and 14 following castration. More surgically castrated dogs required medical intervention than chemically castrated dogs (P=0.0328); the number of dogs requiring surgical repair within each group did not differ (P=0.3421). Seven chemically castrated dogs and 22 surgically castrated dogs experienced swelling, inflammation, and/or ulceration; all were managed medically. Two chemically castrated dogs experienced scrotal ulceration requiring surgical castration at Days 3 and 7. One surgically castrated dog experienced partial incisional dehiscence requiring surgical repair at Day 3. Our results suggest that chemical castration of dogs in field clinics is a feasible alternative to surgical castration, but proper follow-up care should be ensured for at least 7days post-procedurally. PMID- 29183571 TI - Echocardiographic and electrocardiographic parameters during the normal postpartum period in toy breeds of dogs. AB - The aim of this study was to evaluate echocardiographic and electrocardiographic parameters during the normal canine postpartum period. Twenty clinically healthy pregnant bitches of toy breeds (11 Miniature poodles, five Yorkshire terriers, two Maltese terriers and two Bichons Frises) were evaluated on days -3, 3, 10, 17, 24, 38, 52 and 80 relative to parturition (day 0). During the first postpartum week, the width of the interventricular septum in systole, the shortening fraction and the left atrium size decreased, while the left ventricle internal diameter in systole and end systolic stress increased. There were progressive decreases in the velocity of circumferential fibre shortening, stroke volume, cardiac output, and mitral E and A wave values. Systolic blood pressure increased markedly during the first postpartum week to gradually increase thereafter. Heart rate and corrected QT interval progressively decreased, while P wave amplitude increased. QRS complex amplitude decreased in the second week after parturition and then increased during the following weeks. In conclusion, there were changes in systolic function and some structural adaptive changes in the bitch during the first 80days postpartum. In addition, maternal heart rate and corrected QT interval decreased, while P wave and QRS amplitudes increased. PMID- 29183572 TI - Evaluation of interferon-stimulated genes in peripheral blood granulocytes as sensitive responders to bovine early conceptus signals. AB - Early detection of gestation is important in the bovine industry. New methods have been developed to detect gene expression in leucocytes induced by interferon tau (IFNT) as gestation biomarkers. However, it is debatable which blood cell is suitable for detecting gene expression. This study was aimed at confirming whether granulocytes respond to IFNT specifically. Granulocytes and mononuclear cells (MNCs) from cows, and several types of bovine cultured cells, were treated with recombinant (r) IFNT and gene expression was analysed by quantitative real time reverse transcriptase (RT)-PCR and microarray analysis. Expression levels of IFN receptors (R1 and R2) were approximately 30- to 900-fold higher in granulocytes than in other cultured cells, and 1.5- to 2.5-fold higher in MNCs than in granulocytes. Microarray analysis following a 2h recombinant IFNT (rIFNT) treatment revealed expression changes for 900 genes in granulocytes. Genes with expression changes included known IFN-stimulated genes (ISGs; ISG15, OAS1, MX1, and MX2). Eighteen genes were selected following granulocyte microarray analysis and their expression changes were confirmed in early gestation, which revealed that nine genes had significantly higher expression levels in pregnant than in non-pregnant animals. In conclusion, granulocytes specifically responded to rIFNT treatment and the resulting gene expression changes correlated with those in vivo. Microarray analysis indicated that various genes showed expression changes in rIFNT-treated granulocytes, which may result in the identification of alternate candidate genes for the early detection of gestation. These results strongly indicate that gene expression in granulocytes is a suitable tool to determine pregnancy status. PMID- 29183573 TI - Age-dependent physiological dynamics in acid-base balance, electrolytes, and blood metabolites in growing goats. AB - There is a paucity of published data reporting acid-base equilibrium in goats, and no information is available on how the acid-base complexity changes when suckling goat kids become ruminants. The aims of this study were to evaluate young healthy goats for age-related changes in serum proteins, metabolites, and electrolytes; differences in results when the Henderson-Hasselbalch equation or strong ion approaches were used were also assessed. To assess biological variability and reproducibility, two consecutive long-term studies, each lasting from the 6th to 56th week of life (wl), were performed in 15 (Study 1) and 10 (Study 2) animals. Blood gas analysis, serum biochemical analysis, and electrophoresis were performed on venous blood, and acid-base information was obtained using the traditional Henderson-Hasselbalch approach, Stewart's strong ion model, and Constable's simplified strong ion model. In all goats within the first 4-5 months, serum concentrations of glucose, l-lactate, and inorganic phosphate decreased significantly, while serum concentrations of total protein, albumin, and gamma globulin increased. Consequently, nonvolatile weak acids (Atot Alb and Atot TP) increased. At the end of this 'adaptation period', i.e. when milk was replaced by purely plant-based food, significantly lower bicarbonate and base excess values were accompanied by blood pH that shifted towards acidosis. Electrolytes (Na+, K+, Ca2+, and Cl-), anion gap, strong ion difference, and strong ion gap did not show age-dependent trends. In conclusion, somatic growth and development of gastro-intestinal fermentation in growing goats act as complex sources of physiological variability on acid-base equilibrium that was not reflected by the Henderson-Hasselbalch equation only. PMID- 29183574 TI - Assessment of a novel equine tarsocrural experimental joint disease model using recombinant interleukin-1beta and arthroscopic articular sampling of the medial malleolus of the tibia on the standing sedated horse. AB - Joint disease and osteoarthritis are common problems in the horse and numerous experimental studies have been developed to determine the safety and efficacy of new therapies. Synovitis, a critical component of joint disease, has been experimentally induced using recombinant interleukin-1 beta (reIL-1beta) to investigate new joint therapies in a controlled environment, although the use of reIL-1beta has not been reported in the equine tarsocrural joint. A common consequence of performing controlled experiments is that articular tissue collection typically requires general anesthesia or euthanasia. This report describes a minimally invasive surgical biopsy technique to harvest joint tissues from the tarsocrural joint in standing horses. The aims of the study were to assess subjective and objective pain parameters following reIL-1beta induced synovitis in the tarsocrural joint and to describe the surgical technique including the location and quantity of tissues obtained with this method. Experimental synovitis was induced using reIL-1beta in one equine tarsocrural joint of each horse using a randomised controlled design. The minimally invasive surgical technique provided sufficient amounts of articular cartilage from the medial malleolus of the tibia and synovium to perform viability, biochemical and histological assessments without necessitating general anesthesia. The minimally invasive technique also allowed for lameness assessment that could have been influenced by more invasive methods of tissue collection. No incisional or lameness complications were detected after use. The synovitis model and surgical technique provided ample tissue for laboratory evaluation and avoided general anesthesia or sacrifice of the horse. PMID- 29183575 TI - Diagnosis of canine pulmonary thromboembolism by computed tomography and mathematical modelling using haemostatic and inflammatory variables. AB - There is no evidence-based diagnostic approach for diagnosis of pulmonary thromboembolism (PTE) in dogs. Many dogs with diseases that predispose to thrombosis are hypercoagulable when assessed with thromboelastography (TEG), but no direct link has been established. The aims of this study were: (1) to investigate if diseased dogs with PTE, diagnosed by computed tomography pulmonary angiography (CTPA), had evidence of hypercoagulability by TEG; (2) to characterise haemostatic and inflammatory changes in dogs with PTE; (3) to construct models for prediction of PTE based on combinations of haemostatic and inflammatory variables; and (4) to evaluate the performance of D-dimer measurement for prediction of PTE. Twenty-five dogs were included in this prospective observational study (PTE: n=6; non-PTE: n=19). Clot strength G values did not differ between the PTE and non-PTE groups in tissue factor (TF) or kaolin activated TEG analyses. Haemostatic and inflammatory variables did not differ between the two groups. Linear discriminant analysis generated a model for prediction of PTE with a sensitivity and specificity of 100% when TF results were used as TEG data, and a model with sensitivity of 83% and specificity of 100% when kaolin results were used as TEG data. Receiver operating characteristic analysis of D-dimer levels showed that a value of >0.3mg/L yielded a sensitivity of 100% and a specificity of 71.4%. In conclusion, the study supports CTPA as method for diagnosing canine PTE, but shows that TEG alone cannot identify dogs with PTE. Models for prediction of PTE were generated, but require further validation. PMID- 29183576 TI - Geranium intoxication induces detoxification enzymes in the Japanese beetle, Popillia japonica Newman. AB - Popillia japonica is a generalist herbivore that feeds on >300 host plant species in at least 72 plant families. It is unknown why P. japonica, despite possessing active detoxification enzymes in its gut, is paralyzed when feeding on the petals of one of its preferred host plant, Pelargonium*hortorum, or on artificial diet containing quisqualic acid (QA), the active compound in zonal geranium. We hypothesized that Pelargonium*hortorum or QA do not induce activity of the cytochrome P450, glutathione S transferase (GST), and carboxylesterase (CoE) detoxification enzymes in P. japonica. In this study, P. japonica were fed petals of zonal geranium or agar plugs containing QA, or rose petals, another preferred but non-toxic host. Midgut enzyme activities of P450, GST, and CoE were then assayed after 6, 12, or 24h of feeding. In most cases, P450, GST, and CoE activities were significantly induced in P. japonica midguts by geranium petals and QA, though the induction was slower than with rose petals. Induced enzyme activity reached a peak at 24h after consumption, which coincides with the period of highest recovery from geranium and QA paralysis. This study shows that toxic geranium and QA induce detoxification enzyme activity, but the induced enzymes do not effectively protect P. japonica from paralysis by QA. Further investigation is required through in vitro studies to know if the enzymes induced by geranium are capable of metabolizing QA. This study highlights a rare physiological mismatch between the detoxification tool kit of a generalist and its preferred host. PMID- 29183577 TI - Identification and characterisation of seventeen glutathione S-transferase genes from the cabbage white butterfly Pieris rapae. AB - Insect glutathione S-transferases (GSTs) play essential roles in the detoxification of insecticides and other xenobiotic compounds. The cabbage white butterfly, Pieris rapae, is an economically important agricultural pest. In this study, 17 cDNA sequences encoding putative GSTs were identified in P. rapae. All cDNAs include a complete open reading frame and were designated PrGSTd1-PrGSTz2. Based on phylogenetic analysis, PrGSTs were divided into six classes (delta, epsilon, omega, sigma, theta and zeta). The exon-intron organizations of these PrGSTs were also analysed. Recombinant proteins of eight PrGSTs (PrGSTD1, PrGSTD2, PrGSTE1, PrGSTE2, PrGSTO1, PrGSTS1, PrGSTT1 and PrGSTZ1) were heterologously expressed in Escherichia coli, and all of these proteins displayed glutathione-conjugating activity towards 1-chloro-2,4-dinitrobenzene (CDNB). Expression patterns in various larval tissues, at different life stages, and following exposure to sublethal doses of abamectin, chlorantraniliprole or lambda cyhalothrin were determined by reverse transcription-quantitative PCR. The results showed that PrGSTe3, PrGSTs1, PrGSTs2, and PrGSTs4 were mainly transcribed in the fat body, while PrGSTe2 was expressed predominantly in the Malpighian tubules. Four genes (PrGSTe2, PrGSTo4, PrGSTs4 and PrGSTt1) were mainly expressed in fourth-instar larvae, while others were ubiquitously expressed in egg, larval, pupa and/or adult stages. Abamectin treatment significantly upregulated ten genes (PrGSTd1, PrGSTd3, PrGSTe1, PrGSTe2, PrGSTo1, PrGSTo3, PrGSTs1, PrGSTs3, PrGSTs4 and PrGSTt1). Chlorantraniliprole and lambda cyhalothrin treatment significantly upregulated nine genes (PrGSTd1, PrGSTd2, PrGSTe1, PrGSTe2, PrGSTe3, PrGSTs1, PrGSTs3, PrGSTs4 and PrGSTz1) and ten genes (PrGSTd1, PrGSTd3, PrGSTe1, PrGSTe2, PrGSTo1, PrGSTo2, PrGSTs1, PrGSTs2, PrGSTs3 and PrGSTz2), respectively. These GSTs are potentially involved in the detoxification of insecticides. PMID- 29183578 TI - Molluscicidal activity and physiological toxicity of Macleaya cordata alkaloids components on snail Oncomelania hupensis. AB - In order to search new local plant molluscicides for the control of the vectors of schistosomiasis, leaves of Macleaya cordata (Willd) R. Br. were used to extract and separate alkaloid components by thinner acid method and column chromatography, and the molluscicidal effect of alkaloid components against snail Oncomelania hupensis was determined by bioassay. The results showed that 7 alkaloid components (AN1-7) were obtained after extracting and separating alkaloids from the leaves of M. cordata, where AN2 was found being the most toxic against snail O. hupensis with 48h LC50 and LC90 values of AN2 of 6.35mg/L and 121.23mg/L, respectively. Responses of some critical enzymes to AN2, including activities of Alkaline phosphatase (ALP), Alanine aminotransferase (ALT), Aspartate transaminase (AST), Malic dehydrogenase (MDH) and Succinate dehydrogenase (SDH) in both cephalopodium and liver, were also detected through experiments, which also explored esterase isozyme (EST) exposed to AN2 in liver tissue. The results showed that AN2 significantly inhibited the activities of SDH, MDH and esterase isozyme, as AN2 significantly stimulated the activities of ALP, ALT and AST to increase at a low concentration (e.g. 25mg/L), while significantly inhibited the activities of these enzymes at a high concentration (100mg/L). These results indicated that AN2 not only inhibited protein synthesis, and respiratory chain oxidative phosphorylation, but also caused hepatocellular injury and reduced the detoxification ability of liver. PMID- 29183579 TI - Two novel house fly Vssc mutations, D600N and T929I, give rise to new insecticide resistance alleles. AB - The house fly, Musca domestica, is a serious pest because it transmits a large diversity of human and veterinary diseases. Insecticides, particularly pyrethroids, are commonly used to control house flies. However, the evolution of pyrethroid resistance has reduced the effectiveness of these insecticides. A major mechanism of resistance to pyrethroids is target site insensitivity caused by the mutations in the voltage-sensitive sodium channel (Vssc) gene (e.g. kdr [L1014F] and super-kdr [M918T+L1014F]). Recently, two novel Vssc alleles, super kdr+D600N and kdr+T929I were detected in a field collected resistant house fly population in Kansas, USA in 2013. To determine the levels of resistance that these new alleles confer to pyrethroids, we isolated strains having the unique Vssc alleles, but being otherwise congenic to the susceptible strain, aabys. We compared levels of resistance conferred to 14 pyrethroids and determined the inheritance of resistance to 8 pyrethroids. Our results revealed that super kdr+D600N conferred higher levels of resistance to seven pyrethroids relative to super-kdr, and kdr+T929I showed super-kdr-like levels of resistance in house flies. Our results are compared with previous studies and reveal that addition of T929I to the kdr mutation (L1014F) increased resistance to all pyrethroids (except etofenprox), and enhanced resistance by ~1000-fold to acrinathrin and flumethrin. The implications of these results on the evolution of resistance are discussed. PMID- 29183580 TI - Responses in reproductive organs, steroid hormones and CYP450 enzymes in female Mongolian gerbil (Meriones unguiculatus) over time after quinestrol treatment. AB - The aim of this study was to assess the effects and reversibility of the synthetic estrogen compound, quinestrol, on the reproductive organs, steroid hormones, and drug-metabolizing enzymes CYP3A4 and CYP1A2 in liver and kidney over time after two quinestrol treatments in female Mongolian gerbils (Meriones unguiculatus). Female gerbils were treated with 4mg/kg quinestrol (9 gerbils/group, 3 treated group) (1 control group, 0mg/kg) for 3days and treated again after 25days. Animals were killed for collection of samples at 5, 10 and 15days after the second treatment ending. Two interval quinestrol treatments significantly increased uterine weight, with trend of increase over time, but no change could be detected in ovarian weights. Quinestrol treatment increased progesterone and estradiol levels, both with trend of decline over time. Quinestrol increased liver and kidney weights and total enzyme content of CYP3A4 and CYP1A2, with trend of decline over time. On the basis of reversible changes of detoxification enzymes or organs, interval quinestrol treatment effectively and reversibly influenced the reproductive hormone and organ to some extent. PMID- 29183581 TI - Deciphering the toxic effects of organochlorine pesticide, dicofol on human RBCs and lymphocytes. AB - Organochlorine pesticides have generated growing concern owing to their diverse toxicities. In this connection, we have evaluated toxic potential of an acaricide, dicofol (DCF) and its harmful effects on human RBCs and lymphocytes. DCF caused hemolysis and rupture of human erythrocytes as confirmed by scanning electron microscopy (SEM). Significant increase in protein oxidation, lipid peroxidation, ROS production, methemoglobin formation with enhanced activities of superoxide dismutase and catalase but decreased level of reduced glutathione were observed as a result of DCF exposure to human erythrocytes. SEM showed significant DCF induced alterations in RBCs from normal discoid shape to echinocytes. Similarly, lymphocytes showed membrane damage, formation of membrane blebs and distorted cell morphology. In vitro comet assay indicated a significant DNA fragmentation in human lymphocytes upon DCF exposure. These results strongly suggest that DCF induces oxidative stress in RBCs via generation of ROS and alters the cellular architecture directly and indirectly. PMID- 29183582 TI - Azadirachtin induced larval avoidance and antifeeding by disruption of food intake and digestive enzymes in Drosophila melanogaster (Diptera: Drosophilidae). AB - Botanical insecticides are a promising alternative to reduce the harmful effects of synthetic chemicals. Among the botanical biopesticides, azadirachtin obtained from the Indian neem tree Azadirachta indica A. Juss. (Meliaceae) is probably the biorational insecticide with greatest agriculture use nowadays due to its broad insecticide activity. The current study, evaluated the lethal and sublethal effects of azadirachtin on larval avoidance, food intake and digestive enzymes of Drosophila melanogaster larvae as biological model. Azadirachtin was applied topically at two doses LD25 (0.28MUg) and LD50 (0.67MUg) on early third instars larvae. Results evaluated 24h after treatment showed that larvae exhibited significant repellence to azadirachtin and prefer keeping in untreated arenas rather than moving to treated one. In addition, azadirachtin avoidance was more marked in larvae previously treated with this compound as compared with naif larvae (controls). Moreover, azadirachtin treatment decreased significantly the amount of larval food intake. Finally, azadirachtin reduced significantly the activity of larval alpha-amylase, chitinase and protease and increased the activity of lipase. This finding showed that azadirachtin induced behavioral and physiological disruption affecting the ability of the insect to digest food. This rapid installation of avoidance and long term antifeedancy might reinforce the action of azadirachtin and provide a new behavioral strategy for integrated pest management programs. PMID- 29183583 TI - The rescue of botanical insecticides: A bioinspiration for new niches and needs. AB - Crop protection is the basis of plant production and food security. Additionally, there are many efforts focused on increasing defensive mechanisms in order to avoid the damaging effects of insects, which still represent significant losses worldwide. Plants have naturally evolved different mechanisms to discourage herbivory, including chemical barriers such as the induction of defensive proteins and secondary metabolites, some of which have a historical link with bio farming practices and others that are yet to be used. In the context of global concern regarding health and environmental impacts, which has been translated into political action and restrictions on the use of synthetic pesticides, this review deals with a description of some historical commercial phytochemicals and promising proteinaceous compounds that plants may modulate to defeat insect attacks. We present a broader outlook on molecular structure and mechanisms of action while we discuss possible tools to achieve effective methods for the biological control of pests, either by the formulation of products or by the development of new plant varieties with enhanced chemical defenses. PMID- 29183584 TI - Inhibition of glucose-6-phosphate dehydrogenase protects hepatocytes from aluminum phosphide-induced toxicity. AB - Aluminum phosphide (AlP) poisoning is a severe toxicity with 30-70% mortality rate. However, several case reports presented AlP-poisoned patients with glucose 6-phosphate dehydrogenase (G6PD) deficiency and extensive hemolysis who survived the toxicity. This brought to our mind that maybe G6PD deficiency could protect the patients from severe fatal poisoning by this pesticide. In this research, we investigated the protective effect of 6-aminonicotinamide (6-AN)- as a well established inhibitor of the NADP+- dependent enzyme 6-phosphogluconate dehydrogenase- on isolated rat hepatocytes in AlP poisoning. Hepatocytes were isolated by collagenase perfusion method and incubated into three different flasks: control, AlP, and 6-AN+ALP. Cellar parameters such as cell viability, reactive oxygen species (ROS) formation, mitochondria membrane potential collapse (MMP), lysosomal integrity, content of reduced (GSH) and oxidized glutathione (GSSG) and lipid peroxidation were assayed at intervals. All analyzed cellular parameters significantly decreased in the third group (6-AN+AlP) compared to the second group (AlP), showing the fact that G6PD deficiency induced by 6-AN had a significant protective effect on the hepatocytes. It was concluded that G6PD deficiency significantly reduced the hepatotoxicity of AlP. Future drugs with the power to induce such deficiency may be promising in treatment of AlP poisoning. PMID- 29183585 TI - Effects of the plant volatile trans-2-hexenal on the dispersal ability, nutrient metabolism and enzymatic activities of Bursaphelenchus xylophilus. AB - Bursaphelenchus xylophilus causes pine wilt disease (PWD), which severely damages pine species. The plant volatile trans-2-hexenal has strong activity against nematodes, although the precise mechanism of this inhibitory action remains unclear. In this paper, the fumigant effects of the LC10 and LC30 of trans-2 hexenal on B. xylophilus were demonstrated. The trans-2-hexenal treatments significantly inhibited the dispersal ability of nematodes. The results also indicated that trans-2-hexenal affects the metabolism of nutrients and the activity of digestive enzymes. Among detoxifying enzymes, after treatment with trans-2-hexenal, glutathione S-transferase activity increased significantly and general esterase activity decreased significantly. Based on these results, trans 2-hexenal disturbs the normal physiological and biochemical activities of this nematode. These results provide valuable insight into the nematicidal mechanisms of trans-2-hexenal. PMID- 29183586 TI - The protective effects of silybin on the cytotoxicity of thiram in human, rat and chicken cell cultures. AB - The study objective was a determination of thiram cytotoxicity and silybin cytoprotective activity in course of the fungicide impact on cell metabolism and membrane integrity. Firstly, human, rat, chicken hepatoma cells and rat myoblasts cultures were incubated with thiram. The results showed higher sensitivity of myoblasts on thiram exposure than the hepatoma cells. Among hepatoma cells, the chicken cultures were the most sensitive on the fungicide endangering. The mitochondrial activity was the most thiram affected function within all types the cell lines used. When silybin co-acted with thiram, an increase of the cell viability was recorded. The EC50-values were higher for thiram subjected to interaction with silybin than the effect of alone thiram action. The interaction mode between the studied compounds shown by combination index (CI) represented an antagonistic or an additive nature and was depended on thiram concentration, type of the cells and the assay used. Moreover, the morphology changes were dependent on silybin presence in the cell cultures subjected to thiram impact at the same time. Staining with Hoechst 33342 and propidium ioidium revealed the apoptosis cell death in the incubation cultures. Definitely, the results have shown a potential of silybin to protect the cultured cells in course of cytotoxicity induced by thiram. However, future studies taking into account other endpoints of thiram cytotoxicity pathways including species differences and the cytoprotection efficacy could be of interest. PMID- 29183587 TI - Comparison of subacute effects of two types of pyrethroid insecticides using metabolomics methods. AB - In this study, 1H NMR based metabolomics analysis, LC-MS/MS based serum metabolomics and histopathology techniques were used to investigate the toxic effects of subacute exposure to two types of pyrethroid insecticides bifenthrin and lambda-cyhalothrin in mice. Metabolomic analysis of tissues extracts and serum showed that these two types of pyrethroid insecticides resulted in alterations of metabolites in the liver, kidney and serum of mice. Based on the altered metabolites, several significant pathways were identified, which are associated with gut microbial metabolism, lipid metabolism, nucleotide catabolism, tyrosine metabolism and energy metabolism. The results showed that bifenthrin and lambda-cyhalothrin have similarities in disruption of metabolic pathways in kidney, indicating that the toxicological mechanisms of these two types of insecticides have some likeness to each other. This study may provide novel insight into revealing differences of toxicological mechanisms between these two types of pyrethroid insecticides. PMID- 29183588 TI - Heterologous formation of neonicotinoid-sensitive nAChRs containing UNC-38 and UNC-29 subunits from Bursaphelenchus xylophilus. AB - Nicotinic acetylcholine receptor (nAChR) subunits are encoded by a large multigene family and generate a large number of pentameric receptors with various properties. At present, nematode species, such as Caenorhabditis elegans, have the largest number of nAChR subunits. In this study, two nAChR subunits (Bxy-Unc 38 and Bxy-Unc-29) were cloned from Bursaphelenchus xylophilus, a fatal nematode pest on pine trees causing pine wilt disease. When Bxy-Unc-38 and Bxy-Unc-29 were co-expressed in Xenopus oocytes, constructed functional nAChRs showed agonist responses to acetylcholine and imidacloprid, a neonicotinoid insecticide. When complementary RNAs (cRNAs) of Bxy-Unc-38 and Bxy-Unc-29 were injected at different ratios, the assembled nAChRs showed different pharmacological subtypes, especially in terms of the sensitivity to imidacloprid and another two neonicotinoids. At cRNA ratios 1:1 and 1:5 (Bxy-Unc-38: Bxy-Unc-29), nAChRs showed low sensitivity to test neonicotinoids, which were partial agonists on the receptors. In contrast, at cRNA ratio 5:1, the three test neonicotinoids were full agonists and showed much higher potency compared to that on the receptors with cRNA ratio 1:1 and 1:5. For example, EC50 values of the three neonicotinoids on the receptors with cRNA ratio 1:5 were 170-222 times of those of receptors with cRNA ratio 5:1. The results showed that the subunit stoichiometry of Bxy-Unc 38/Bxy-Unc-29 receptor dramatically affected the agonist potency of neonicotinoids, and even altered the action property. Due to the high sensitivity of the constructed nAChRs at cRNA ratio 5:1, the construct would serve as an important model to study the interaction between invertebrate nAChRs and neonicotinoids. PMID- 29183589 TI - Novaluron ingestion causes larval lethality and inhibits chitin content in Leptinotarsa decemlineata fourth-instar larvae. AB - To accomplish consistent, long-term, integrated management (IPM) of the Colorado potato beetle, Leptinotarsa decemlineata (Say), research assessing the potential of novel, IPM-compatible insecticides is essential. Novaluron is a potent benzoylurea insecticide. In the present paper, we found that novaluron ingestion by the fourth-instar larvae inhibited foliage consumption, reduced larval fresh weight, and delayed development period, in a dose dependent manner. Most of the resulting larvae fail to pupate, and died at prepupae stage, with larvicidal activity comparable with those of cyhalothrin and spinosad but lower than those of fipronil and abamectin. Moreover, many surviving pupae that fed novaluron failed to emerge as adults, in a dose dependent pattern. Furthermore, feeding of novaluron significantly decreased chitin contents in body carcass (without midgut) and integument specimen, whereas the chitin concentration in the midgut peritrophic matrix was not affected. Furthermore, uridine diphosphate-N acetylglucosamine-pyrophosphorylase gene (LdUAP1) and chitin synthase Aa (LdChSAa), which were mainly responsible for chitin biosynthesis in ectodermally derived tissues, were surpressed and activated respectively after novaluron ingestion. Therefore, novaluron is an effective benzoylurea insecticide to L. decemlineata fourth-instar larvae. It inhibited chitin biosynthesis in ectodermally-derived tissues, disrupted ecdysis, impaired pupation and adult emergence, and led to death in juvenile life stages.

AB - The antifungal properties and the induction of resistance by epsilon-poly-l lysine (epsilon-PL) were examined to reveal its potential in protecting tomato plants against Botrytis cinerea. As presented herein, epsilon-PL at 1200mg/L was found to have optimal in vitro antifungal activities, achieving an inhibition rate of 94.96%. In first-year field tests, epsilon-PL (1200mg/L) had a control effect of up to 79.07% against tomato grey mould. Similar results were obtained in the second year. In greenhouse experiments, epsilon-PL was observed to effectively reduce leaf infection, with an observed control rate at 89.22%. To define the molecular-genetic mechanisms, we compared the gene expression under four different conditions: sterile water sprayed plants (Control), Botrytis infected plants (Inf), epsilon-PL-treated plants (epsilon-PL) and epsilon-PL treated+infected plants (epsilon-PL+Inf). Quantitative PCR analysis at 36h after inoculation revealed that epsilon-PL+Inf plants exhibited significant expression and priming of several key Botrytis-induced genes in tomato. The results indicate that epsilon-PL promoted plant capacity of tomato to activate defense mechanisms upon pathogen attack. In total, these findings revealed that epsilon-PL should be an excellent biocontrol agent candidate that combined direct antifungal activity against B. cinerea and plant resistance capacity.

PMID- 29183590 TI - Genetic mutations in sodium channel domain II and carboxylesterase genes associated with phenotypic resistance against synthetic pyrethroids by Rhipicephalus (Boophilus) decoloratus ticks in Uganda. AB - We previously reported emergence of super synthetic pyrethroid (SP) resistant Rhipicephalus (Boophilus) decoloratus ticks in Uganda. This study investigated the genetic basis of phenotypic resistance against SP in R. (B.) decoloratus and sought to identify novel diagnostic mutations for rapid detection of SP resistance in the above tick species. Genomic DNA was extracted from pooled larvae of 20 tick populations (19 of known SP susceptibility and 1 unknown susceptibility). The voltage sensitive sodium channel (VSSC) domain II S4-5 linker (SP target) and partial carboxylesterase (SP metabolizing enzyme) genes were amplified by PCR, cloned and sequenced. The resultant sequences were analyzed to determine single nucleotide polymorphisms (SNPs) associated with phenotypic resistance in the various tick populations investigated. Novel SNPs that introduced Eco RI and Eco RII restriction sites in carboxylesterase gene were identified in silco and validated with restriction fragment length polymorphism (RFLP) against 18 tick populations of known SP susceptibility. The study identified a super knock down resistance (kdr) mutation T58C in R. (B.) decoloratus VSSC associated with stable SP resistance. We further identified multiple nonsynonymous mutations in carboxylesterase of SP resistant ticks; one of which conferred novel EcoRII (G195C) restriction site for PCR-RFLP detection of SP resistance. In conclusion, this study is the first to report super kdr mutation in sodium channel domain II and multiple mutations in carboxylesterase genes that may concurrently mediate stable resistance against synthetic pyrethroids in R. (B.) decoloratus ticks from Uganda. The Eco RII based PCR-RFLP is a useful tool for rapid detection of stable SP resistant R. (B.) decoloratus ticks.

AB - The evolution of weed-resistant species threatens the sustainable use of glyphosate, which is the most important herbicide widely used in agriculture worldwide. Moreover, the high glyphosate resistance (>180-fold based on LD50) of Eleusine indica found in Malaysia, which carries a double mutation in its 5 enolpyruvylshikimate-3-phosphate synthase (EPSPS), made the control of this species more difficult. By contrast, the same species carrying the same double mutation in EPSPS (T102I+P106S) but found in China only shows a resistance level of not more than 14-fold based on GR50. The resistance level of this population is four times higher than that of the population carrying a single mutation (P106L). Although the members of this population survive under a high glyphosate dosage of 10,080gaeha-1, their growth was significantly inhibited by glyphosate under the recommend dose (840gaeha-1), where in the fresh weight was 85.4% of the control. EPSPS expression, relative copy number, and EPSPS activity in this population were similar to those of the susceptible population. In addition, the expression of two glutathione transferase (GST) genes (GST-U8 and GST-23) and the enzyme activity of the GST in this population did not significantly differ from those of the susceptible population. This finding is important in elucidating the resistance of the naturally evolved glyphosate-resistant (GR) weed species carrying a double mutation in EPSPS to glyphosate. PMID- 29183594 TI - The distribution and species of Ca2+ and subcellular localization of Ca2+ and Ca2+-ATPase in grape leaves of plants treated with fluoroglycofen. AB - Fluoroglycofen, a post-emergence herbicide used in vineyards to eradicate weeds, has previously been shown to turn grape leaves dark green following its use. Therefore, this study evaluates the relationship of dark green leaves with calcium form and subcellular distribution. To do this, we focused on the Ca2+ distribution and Ca2+-ATPase activity in leaf cells of one-year-old self-rooted Chardonnay grapevines treated with fluoroglycofen. Plants were separated into different treatments when they had seven or eight leaves, and different concentrations of fluoroglycofen were sprayed on the sand. The results showed that all of the soluble calcium content in the grape leaves that were treated with the highest concentration of fluoroglycofen (187.5gaiha-1) increased significantly. Specifically, the water-soluble organic acid calcium, pectate calcium, and calcium oxalate increased by 18.43%, 17.14%, and 31.05%, respectively, in the upper leaves than in the control. The subcellular distribution of Ca2+ in the dark green leaves increased significantly, especially in the cell wall and chloroplast, which increased by 25.54% and 24.10%, respectively. Through the ultrastructure localization of Ca2+ and Ca2+-ATPase contrasted with the control, the extracellular space and chloroplasts in the mesophyll cells of dark green leaves had large calcium pyroantimonate (Ca-PA) deposits. The extracellular space had fewer Ca2+-ATPase precipitation particles, whereas the chloroplasts had more. At the same time, a high concentration of fluoroglycofen decreased Ca2+-ATPase activity in grape leaves, which potentially might be due to disrupted regulation of calcium homeostatic mechanisms inside and outside of cells, resulting in a large number of Ca2+ accumulation in cells. The Ca2+ accumulation not only hindered the various cellular physiological reactions, but also caused leaves to become dark green in color. PMID- 29183595 TI - Interactions between salicylic acid and antioxidant enzymes tilting the balance of H2O2 from photorespiration in non-target crops under halosulfuron-methyl stress. AB - Halosulfuron-methyl (HSM) is a safe, selective and effective sulfonylurea herbicide (SU) for the control of sedge and broadleaf weeds in sugarcane, corn, tomato, and other crops. The primary site of action is acetolactate synthase (ALS), a key enzyme of branched chain amino acids (BCAAs) synthesis. In addition to ALS inhibition, BCAAs deficiencies and oxidative damage may be involved in toxic effects of SUs. However, secondary targets of HSM relevant to plant physiological responses are unclear. In the present study, comparative growth inhibition and peroxidization injury between sensitive and tolerance crops were observed at biochemical and physiological levels suggesting involvement of H2O2, ethylene, salicylic acid (SA) in the oxidative stress responses to HSM. HSM caused accumulation of H2O2, stimulated photorespiration and consequent accumulation of SA that worsened the peroxidization injury to the sensitive C3 plant soybean (Glycine max). The growth inhibition at low concentrations of HSM could be lessened by supplementary BCAAs, reactive oxygen species scavengers or ethylene inducers, whereas the oxidation damage at high concentrations of HSM could not be reversed and ultimately lead to plant death. H2O2 at a low level stimulated the antioxidase system including glutathione S-transferase activities in the HSM-tolerant C4 maize (Zea mays), which contributes to HSM tolerance. H2O2 plays an important role on HSM stress responses in both HSM-sensitive and HSM tolerant soybean and maize. PMID- 29183596 TI - Effect of allelochemical tricin and its related benzothiazine derivative on photosynthetic performance of herbicide-resistant barnyardgrass. AB - Despite increasing knowledge of allelochemicals as leads for new herbicides, relatively little is known about the mode of action of allelochemical-based herbicides on herbicide-resistant weeds. In this study, herbicidal activities of a series of allelochemical tricin-derived compounds were evaluated. Subsequently, a benzothiazine derivative 3-(2-chloro-4-methanesulfonyl)-benzoyl-hydroxy-2 methyl-2H-1,2-benzothiazine-1,1-dioxide with 4-hydroxyphenyl-pyruvate dioxygenase (HPPD) inhibiting activity was identified as a target compound on photosynthetic performance of penoxsulam-resistant versus -susceptible barnyardgrass (Echinochloa crus-galli). Regardless of barnyardgrass biotype, the benzothiazine derivative greatly affected chlorophyll fluorescence parameters (Fv/Fm, ETR1min and NPQ1min), reduced the chloroplast fluorescence levels and expression of HPPD gene. In particular, the benzothiazine derivative interfered with photosynthetic performance of resistant barnyardgrass more effectively than the allelochemical tricin itself. These results showed that the benzothiazine derivative effectively inhibited the growth of resistant barnyardgrass and its mode of action on photosynthesis system was similar to HPPD-inhibiting sulcotrione, making it an ideal lead compound for further development of allelochemical-based herbicide discovery. PMID- 29183597 TI - Resistance to quinclorac caused by the enhanced ability to detoxify cyanide and its molecular mechanism in Echinochloa crus-galli var. zelayensis. AB - Quinclorac, an auxin-type herbicide, is widely used to control barnyardgrass and some dicotyledon weeds. Echinochloa crus-galli var. zelayensis, a variety of E. crus-galli (L.) Beauv., is widespread in China and some populations have resistance to quinclorac. E. crus-galli var. zelayensis seeds with varying sensitivity to quinclorac were used in the present study. The expression of the ADP/ATP carrier protein (ANT) gene, which plays an important role in the maintenance of cellular energy balance, dramatically rose in the S biotype after exposure to quinclorac, while no change was found in two R biotypes. The activity of beta-cyanoalanine synthase (beta-CAS), which is the key enzyme for cyanide degradation, was higher in two R biotypes than in the S biotype before and after treatment with quinclorac. One single-nucleotide difference was detected in the EcCAS gene of two R biotypes compared with the S biotype. The nucleotide change, which caused one amino acid substitution, replacing Methionine (Met)-295 with Lysine (Lys)-295 in the two R biotypes, which are same as the rice beta-CAS gene at this position. In addition, EcCAS gene expression was higher in the two R biotypes than in the S biotype. In conclusion, beta-CAS may play a crucial role in the resistance of E. crus-galli var. zelayensis to quinclorac. EcCAS gene mutation and higher gene expression may enhance the activity of beta-CAS to avoid the accumulation of toxic cyanide in resistant populations, thus contributing to the resistance mechanism of E. crus-galli var. zelayensis. to quinclorac. PMID- 29183598 TI - Tribenuron-methyl resistance and mutation diversity of the AHAS gene in shepherd's purse (Capsella bursa-pastoris (L.) Medik.) in Henan Province, China. AB - Shepherd's purse is a troublesome dicot weed that occurs in the major wheat producing areas in China. Twenty-eight shepherd's purse populations were collected from winter wheat-planting areas in Henan Province and used to evaluate tribenuron-methyl resistance and acetohydroxyacid synthase (AHAS) gene-mutation diversity. The results indicate that all 28 shepherd's purse populations were resistant to tribenuron-methyl at different levels compared with the susceptible population. Mutation of the 197 codon (CCT) changed proline (Pro) into tyrosine (Tyr), histidine (His), leucine (Leu), serine (Ser), arginine (Arg), alanine (Ala) and threonine (Thr), whereas mutation of the 574 codon (TGG) changed tryptophan (Trp) into leucine (Leu). Among these amino acid changes, a co concurrence of Pro197Leu and Trp574Leu substitutions was identified for the first time in resistant weed species. Furthermore, Pro197Tyr, Pro197Arg and Pro197Ala substitutions have not been previously reported in shepherd's purse. The results of the in vitro AHAS assay suggest that an insensitive AHAS is likely involved in the resistance to tribenuron-methyl in the R populations with AHAS gene mutations, and the non-target-site based resistance might exist in some populations. PMID- 29183599 TI - Design, synthesis, and herbicidal activity of novel quaternary ammonium salt derivatives. AB - A series of novel quaternary ammonium salt derivatives were designed and synthesized by introducing the herbicide carboxylic acid into substituted aminoacetanilide compounds which derived from herbicides alachlor or acetochlor, using the intermediate derivatization methods in an attempt to obtain novel candidates for weed control. The herbicidal activity assays in greenhouse demonstrated that some of the title compounds exhibited good herbicidal activities against velvet leaf, youth-and-old age, barnyard grass, and foxtail. Especially, III9 gave the best activity (EC50 (ga.i/ha): YOA 34.1, VEL 33.6, FOX 15.9, BYG 36.2). The field trials indicated that III9 had better herbicidal activity than the commercial herbicide imazethapyr to control broadleaf weeds at 150ga.i/ha. The present work demonstrated that the quaternary ammonium salt derivatives can be used as potential lead compounds for discovering novel herbicides with improved activity. III9 itself is worthy of being further developed as an herbicidal candidate. Further syntheses, structure optimization studies, and field trials around III9 are in progress. PMID- 29183600 TI - Recent advances in tenuazonic acid as a potential herbicide. AB - Tenuazonic acid (TeA), belonging to tetramic acids that are the largest family of natural products, is a mycotoxin produced by members of the genus Alternaria and other phytopathogenic fungi. TeA has many desirable bioactivities. In the past two decades, several studies have addressed its phytotoxic activity. Because it can cause brown leaf spot and kill seedlings of mono- and dicotyledonous plants, TeA is regarded as a potential herbicidal agent. TeA blocks electron transport beyond QA by interacting with D1 protein and is a PSII inhibitor. The chloroplast derived oxidative burst is responsible for TeA-induced cell death and plant necrosis. Based on the model of molecular interaction between TeA and D1 protein, a series of its derivatives with stable herbicidal activity have been designed, evaluated and patented. Recently, some chemical synthetic approaches of TeA and its derivatives have been successfully developed. This paper will mainly focus on new developments regarding TeA's herbicidal activity, mode of action, biosynthesis and chemical synthesis, and characterization of new derivatives. PMID- 29183601 TI - Involvement of H2O2 in fluazifop-P-butyl-induced cell death in bristly starbur seedlings. AB - In order to understand the action mechanism of fluazifop-P-butyl (FB) in bristly starbur (Acanthospermum hispidum D.C.), a susceptible plant, the role of active oxygen species (ROS) in herbicide-induced cell death in shoots was investigated. FB-induced phytotoxicity was not reduced by the antioxidants, 1,4 diazabicyclooctane (dabaco), sodium azide, l-tryptophan, d-tryptophan, hydroquinone and dimethyl pyridine N-oxide (DMPO). The activities of superoxide dismutase (SOD) and catalase (CAT), in bristly starbur seedlings were significantly increased by FB at 12 HAT and 24 HAT, while ascorbate peroxidase (APX) and glutathione reductase (GR) activities increased only at 12 HAT. The contents of H2O2 in FB-treated bristly starbur seedlings were significantly higher to that of control between 8 and 24 HAT. According to the analysis of potassium iodide - starch or 3,3-diaminobenzidine, the accumulation of hydrogen peroxide was observed in the apical growing point, stem, petiole and veins of FB treated bristly starbur seedlings at 24 HAT. The cell viability of bristly starbur seedlings treated by 10MUM FB decreased at 18 HAT. These results suggested that FB-induced cell death in bristly starbur shoots may be caused by ROS (O2- and H2O2) generation and lipid peroxidation. PMID- 29183602 TI - Copper complexes of the 1,3,4-thiadiazole derivatives modulate antioxidant defense responses and resistance in tomato plants against fungal and bacterial diseases. AB - The metallic complexes MU-chloro-MU-[2,5-bis (2-pyridyl)-1,3,4-thiadiazole] aqua chlorocopper (II) dichlorocopper (II) (abbreviated 2PTH-Cu2-Cl4); aquabis [2,5 bis (2-pyridyl)-1,3,4-thiadiazole-kappa2N2,N3] (trifluoromethane-sulfonato kappaO) copper(II) trifluoro metrhanesulfonate (2PTH-Cu-tF) and bis[(2,5 bis(pyridine-2-yl)-1,3,4-thiadiazole-di-azido copper(II)] (2PTH-Cu-Az) were compared for their antimicrobial activities in vitro, and their aptitude to control Verticillium wilt and crown gall diseases development of tomato in the greenhouse. Results showed that the complex 2PTH-Cu-Az inhibited drastically the growth of V. dahliae in vitro. 2PTH-Cu2-Cl4 and 2PTH-Cu-tF did not display any noticeable antimicrobial activity in vitro against all of the pathogens tested. However, in planta evaluation revealed that the three complexes protected tomato against crown gall similarly. They also reduced Verticillium wilt disease severity, although the complex 2PTH-Cu-Az was the most efficient. When compared to other complexes, 2PTH-Cu-Az triggered only a weak oxidative burst as revealed by H2O2 measurement and the activity of ascorbate peroxidase and catalase. These results suggest that the superiority of 2PTH-Cu-Az against V. dahliae rely on its direct antifungal activity and its ability to modulate H2O2 accumulation. PMID- 29183603 TI - Characterization of glutathione S-transferases in the detoxification of metolachlor in two maize cultivars of differing herbicide tolerance. AB - Glutathione S-transferases (GSTs) have been widely studied in relation to their role in herbicide tolerance and detoxification. However, a detailed characterization of GSTs from herbicide tolerant and sensitive maize cultivars is still lacking. In this study, we determined the mechanism of differential tolerance between two maize cultivars which had 4-fold difference tolerance to metolachlor. The metabolism rate of metolachlor was more rapid in the tolerant cultivar (Zea mays L. cv Nongda86) than the susceptible one (Zea mays L. cv Zhengda958). Addition of the GST inhibitor ethacrynic acid reduced the metabolism of metolachlor indicating the involvement of GSTs in the differential detoxification of metolachlor. The expression profiles of 32 GST isozymes were measured using quantitative RT-PCR. The results showed the expression of GST genes were slightly up-regulated in Nongda86, but severely inhibited in Zhengdan958 24h after metolachlor treatment. The genes GSTI, GSTIII, GSTIV, GST5, GST6 and GST7, which can detoxify chloroacetanilide herbicides, were all expressed higher in Nongda86 compared to Zhendgan958. The result of GST activity was consistent with the gene expression profiles. Collectively, higher-level expression of GST genes, leading to higher GST activity and faster herbicide detoxification, appears to be responsible for the difference in tolerance to metolachlor in two maize cultivars. PMID- 29183604 TI - Microbial catabolism of chemical herbicides: Microbial resources, metabolic pathways and catabolic genes. AB - Chemical herbicides are widely used to control weeds and are frequently detected as contaminants in the environment. Due to their toxicity, the environmental fate of herbicides is of great concern. Microbial catabolism is considered the major pathway for the dissipation of herbicides in the environment. In recent decades, there have been an increasing number of reports on the catabolism of various herbicides by microorganisms. This review presents an overview of the recent advances in the microbial catabolism of various herbicides, including phenoxyacetic acid, chlorinated benzoic acid, diphenyl ether, tetra-substituted benzene, sulfonamide, imidazolinone, aryloxyphenoxypropionate, phenylurea, dinitroaniline, s-triazine, chloroacetanilide, organophosphorus, thiocarbamate, trazinone, triketone, pyrimidinylthiobenzoate, benzonitrile, isoxazole and bipyridinium herbicides. This review highlights the microbial resources that are capable of catabolizing these herbicides and the mechanisms involved in the catabolism. Furthermore, the application of herbicide-degrading strains to clean up herbicide-contaminated sites and the construction of genetically modified herbicide-resistant crops are discussed. PMID- 29183605 TI - Synthesis and herbicidal activity of optically active alpha-(substituted phenoxyacetoxy) (substituted phenyl) methylphosphonates. AB - alpha-(Substituted phenoxyacetoxy) alkylphosphonates containing one chiral carbon atom have been demonstrated to be PDHc inhibitor with good herbicidal activity and some of them could be used as potential herbicide. In order to determine any difference in herbicidal activities between (R) and (S) isomers, the synthetic method of optically active substituted phenylalkylphosphonates IB were explored. A highly practical, enantioselective hydrophosphonylation was developed to prepare optically active O,O-dimethyl alpha-hydroxyalkylphosphonates 3 as key intermediate by asymmetric addition reaction of dimethylphosphite 1 and several kinds of aldehydes 2 using tridentate Schiff base Al(III) complexes as catalysts. A series of novel O,O-dimethyl alpha-(substituted phenoxyacetoxy)(substituted phenyl)methylphosphonates IB including (R) and (S) enantiomers were further synthesized with excellent enantioselectivity (95-99% ee) by the condensation of optically active alpha-hydroxyl (substituted phenyl)methylphosphonates 3 and substituted phenoxyacetyl chlorides 4. The herbicidal activities of title compound IB including their racemates, (R) and (S) enantiomers were evaluated in greenhouse for post-emergence application. All compounds IB showed significant inhibitory activity against dicotyledonous plants. A difference in herbicidal effect among racemate, (R) and (S) enantiomers were observed. Especially IB7 and IB10 showed obvious chiral selectivity in inhibitory activity against chickweed. (S)-IB7 with ED50 of 22.8gai/ha was found to be most effective enantiomer against chickweed and its inhibitory activity was 8.17 times higher than (R)-IB7. (S)-IB7 as potential herbicide would be effective at lower rates than (R)-IB7 or (rac) IB7. PMID- 29183606 TI - Mechanism of resistance to cyhalofop-butyl in Chinese sprangletop (Leptochloa chinensis (L.) Nees). AB - Chinese sprangletop (Leptochloa chinensis (L.) Nees) is a serious grass weed in rice paddies. In some areas, L. chinensis has become resistant to the herbicide cyhalofop-butyl because of its frequent and extensive use over the past five years. In this study, whole-plant dose-response assays were conducted, and a L. chinensis population (ZHYH) had a 75.8-fold resistance index to cyhalofop-butyl. Molecular analyses revealed that this resistance was attributed to a tryptophan (Trp)-2027-to-cysteine (Cys) substitution in the CT domain of the ACCase gene. To our knowledge, this is the first report revealing the mechanism underlying cyhalofop-butyl resistance in L. chinensis. Furthermore, a derived cleaved amplified polymorphic (dCAPS) assay was developed to rapidly detect the Trp-2027 Cys mutation. Of the 100 ZHYH plants analyzed, 52 were heterozygous mutants and 48 were susceptible homozygous plants. In addition, the cyhalofop-butyl-resistant L. chinensis was cross-resistant to aryloxyphenoxypropionate and phenylpyrazoline herbicides, but not to cyclohexanedione, acetolactate synthase-inhibiting, protoporphyrinogen oxidase, and urea herbicides, and had only slight resistance to the hormonal herbicide quinclorac. PMID- 29183607 TI - Fluazifop-P-butyl induced ROS generation with IAA (indole-3-acetic acid) oxidation in Acanthospermum hispidum D.C. AB - Acanthospermum hispidum D.C. was particularly susceptible to fluazifop-P-butyl, an aryloxyphenoxypropionate herbicide, and the primary action site for the herbicide was shoot apical meristem, which is also the main site of indole-3 acetic acid (IAA) biosynthesis and action. Membrane lipid peroxidation caused by increasing levels of reactive oxygen species (ROS) was considered as an action mechanism of fluazifop-P-butyl in A. hispidum. To further clarify the ROS inducing mechanism of fluazifop-P-butyl in the plant, the interactions between fluazifop-P-butyl and auxin compounds IAA or 2,4-dichlorophenoxyacetic acid (2,4 D) were studied. Haloxyfop-P-methyl, an AOPP herbicide which is inactive on A. hispidum, was used for comparison. The results showed that the growth inhibition and malondialdehyde or H2O2 increases induced by fluazifop-P-butyl on A. hispidum were reversed by IAA or 2,4-D. The IAA content was decreased but the contents of three IAA oxidation metabolites, indole-3-methanol, indole-3-aldehyde and indole 3-carboxylic acid were increased by fluazifop-P-butyl in A. hispidum, but not by haloxyfop-P-methyl. The growth of A. hispidum was not inhibited by three IAA oxidative compounds. Moreover, the activities of IAA oxidase and peroxidase were increased by fluazifop-P-butyl but not by haloxyfop-P-methyl, and the increase was reversed by IAA or 2,4-D. We suggest that there is an antagonistic effect between fluazifop-P-butyl and IAA or 2,4-D, and the IAA oxidation may be involved in the action mechanism of fluazifop-P-butyl in A. hispidum. PMID- 29183608 TI - N'-mono- and N, N'-diacyl derivatives of benzyl and arylhydrazines as contact insecticides against adult Anopheles gambiae. AB - New public health insecticides are urgently required to prevent the spread of vector-borne disease. With the goal of identifying new K+-channel-directed mosquitocides, analogs of the RH-5849 family of diacyl t-butylhydrazines were synthesized and tested for topical toxicity against adult Anopheles gambiae, the African vector of malaria. In total, 80N'-monoacyl and N, N'-diacyl derivatives of benzyl- and arylhydrazines were prepared. Three compounds (2bo, 2kb, 3ab) were identified that were more toxic than RH-5849 and RH-1266. The potencies of these compounds to block K+ currents in An. gambiae and human Kv2.1 channels were assessed to address their possible mechanism of mosquitocidal action. Selectivity for inhibition of An. gambiae Kv2.1 vs human Kv2.1 did not exceed 3-fold. Furthermore, no correlation was seen between the potency of insecticidal action and K+ channel blocking potency. These observations, combined with the minimal knockdown seen with 2bo near its LD50 value, suggests a mode of action outside of the nervous system. PMID- 29183609 TI - Monitoring insecticide resistance and diagnostics of resistance mechanisms in the green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae) in China. AB - Myzus persicae (Sulzer) is one of the most serious agricultural pests in China, and management strategies mainly rely on insecticidal treatment. To evaluate the resistance of field populations of M. persicae to seven insecticides, we assessed the susceptibility of 11 field populations collected from eight provinces in China using leaf-dip bioassays. Toxicity assays showed that M. persicae field populations have developed several levels of resistance to each tested insecticide. For pyrethroids, the field populations have developed a high level of resistance to beta-cypermethrin and cypermethrin, while the resistance to bifenthrin is still low. The resistance ratios of field populations to imidacloprid ranged from 1.48 to 52.36, and eight populations have developed moderate to high resistance. Resistance to acetamiprid is low, and only two populations have a moderate level of resistance. Most of the field populations of M. persicae developed moderate to high resistance to methomyl and omethoate. To investigate potential resistance mechanisms, we analyzed the enzyme activity of carboxylesterases, the type of amplified esterase genes, as well as the kdr (L1014F) mutation. All of the field populations exhibited a higher esterase activity compared to the laboratory susceptible strain. An amplified FE4, as well as the L1014F mutation, were also found in all of our experimental field populations. These results provide valuable insight into the current status of insecticide resistance and will prove to be a valuable resource in designing appropriate resistance management strategies for M. persicae in China. PMID- 29183610 TI - Chlorine dioxide enhances lipid peroxidation through inhibiting calcium independent cellular PLA2 in larvae of the Indianmeal moth, Plodia interpunctella. AB - Polyunsaturated fatty acids usually undergo lipid peroxidation induced by reactive oxygen species (ROS). Calcium-independent cellular phospholipase A2 (iPLA2) can maintain fatty acid compositions in phospholipids depending on physiological conditions. An insect iPLA2 (Pi-iPLA2) was predicted from the transciptome of the Indianmeal moth, Plodia interpunctella. It encodes 835 amino acids. It possesses five ankyrin repeats in the N terminal and patatin lipase domain in the C terminal. Pi-iPLA2 was expressed in all developmental stages of the Indianmeal moth. In the larval stage, it was expressed in all tissues tested. RNA interference (RNAi) specific to Pi-iPLA2 was performed using specific double stranded RNA (dsRNA). It resulted in almost 70% of reduction in gene expression. Under such RNAi condition, P. interpunctella exhibited significant accumulation of lipid peroxidation based on the amount of malondialdehyde. RNAi of Pi-PLA2 expression also impaired cellular immune response of P. interpunctella. Chlorine dioxide (ClO2), an insecticidal agent by generating ROS, increased lipid peroxidation in a dose-dependent manner. However, the addition of vitamin E (an antioxidant) reduced the formation of lipid peroxidation. ClO2 treatment significantly reduced expression of Pi-iPLA2 but increased lipid peroxidation in larval fat body of P. interpunctella. Furthermore, larvae treated with dsRNA specific to Pi-iPLA2 were significantly susceptible to ClO2 treatment. These results suggest that Pi-iPLA2 plays a crucial role in repairing damaged fatty acids from phospholipids. Our results also suggest that ClO2 can elevate lipid peroxidation through inhibiting Pi-iPLA2 expression in addition to direct ROS production. PMID- 29183611 TI - The R81T mutation in the nicotinic acetylcholine receptor of Aphis gossypii is associated with neonicotinoid insecticide resistance with differential effects for cyano- and nitro-substituted neonicotinoids. AB - The cotton aphid, Aphis gossypii Glover, is one of the most agriculturally important insect pests. Neonicotinoid insecticides and sulfoxaflor have generally shown excellent control of A. gossypii, but these aphids have recently developed resistance against neonicotinoid insecticides. We previously characterized a field-collected A. gossypii Kushima clone that showed higher resistance to nitro substituted neonicotinoids, such as imidacloprid, than to cyano-substituted neonicotinoids, such as acetamiprid. This Kushima clone harbors the R81T mutation in the nicotinic acetylcholine receptor (nAChR) beta1 subunit; this mutation is the source of neonicotinoid insecticide resistance. In the present study, electrophysiological analyses and molecular modeling were employed to investigate the differential effects of the R81T mutation on cyano- and nitro-substituted neonicotinoids and sulfoxaflor. We isolated full-length coding sequences of A. gossypii nAChR alpha1, alpha2, and beta1 subunits. When co-expressed in Xenopus laevis oocytes with chicken beta2 nAChR, A. gossypii alpha1 evoked inward currents in a concentration-dependent manner in response to acetylcholine (ACh) and showed sensitivity to neonicotinoid and sulfoxaflor. Additionally, the chicken beta2 T77R+E79V (equivalent double mutant of R81T) mutation resulted in a lower effect to cyano-substituted neonicotinoids and sulfoxaflor than to nitro substituted neonicotinoids. Electrophysiological data and nAChR homology modeling analysis suggested that the Kushima clone exhibited different levels of resistance to cyano- and nitro-substituted neonicotinoid insecticides.

AB - Resistance to 2,4-D (2,4-diclorophenoxyacetic acid) herbicide is increasing in various dicotyledonous weed species, including Papaver rhoeas, a weed infesting Southern European wheat crops. Non-target-site resistance to this herbicide is governed by a range of genes involved in herbicide stress response. To enable reliable measurement of gene expression levels in herbicide-resistant and susceptible plants it is necessary to normalize qPCR data using internal control genes with stable expression. In an attempt to find the best reference genes, the stability of seven candidate reference genes was assessed in plants resistant and susceptible to 2,4-D, subjected or not to herbicide stress. Using three statistical algorithms (geNorm, BestKeeper and NormFinder), the overall results revealed that glyceraldehyde-3-phosphate dehydrogenase, actin and ubiquitin were the most stable reference genes. The normalization expression levels of GH3 (indole-3-acetic acid amido synthetase) and GST3 (glutathione S-transferase) which are two genes up-regulated following 2,4-D treatment, were determined to verify the stability of these selected reference genes. A sudden increase in GH3 and GST3 expression was already detected 5h after herbicide application, confirming their involvement in plant response to 2,4-D. The validation results confirmed the applicability and accuracy of these reference genes. This study identified and validated reference genes in the non-model weed species P. rhoeas and these will facilitate gene expression analysis studies aimed at identifying functional genes associated with non-target-site resistance.

AB - Control failures with the use of pyrethroid insecticides have been reported frequently for populations of Helicoverpa armigera (Hubner) in Brazil, since its detection in 2013. Here, we confirmed and investigated the metabolic mechanisms of pyrethroid resistance in H. armigera populations from Brazil. Mortality of H. armigera populations was lower than 50% at the highest dose (10MUg a.i./3rd instar larva) of the pyrethroids deltamethrin and fenvalerate in dose-response bioassays. Very low mortality (10 to 40%) was obtained at a diagnostic dose of 10MUg a.i./larva for each pyrethroid in H. armigera populations collected from different agricultural regions in Brazil, from 2013 to 2016. In synergist bioassays, when larvae were treated with PBO synergist, the mortality of all populations tested was 100%. The frequency of the cytochrome P450 CYP337B3 gene was above 0.95 in all populations of H. armigera. We found only fourteen heterozygous H. armigera out of 497 individuals tested for this gene subfamily. Our results indicated that H. armigera populations from Brazil have different degrees of susceptibility to deltamethrin and fenvalerate, but all populations can be considered tolerant to pyrethroid insecticides. The chimeric P450 CYP337B3 enzyme is one of the main mechanisms of pyrethroid resistance in Brazilian H. armigera populations.

AB - Phenazine-1-carboxylic acid (PCA) is a natural product that has been proven effective against a number of soil-borne fungal phytopathogens and registered for biofungicide against rice sheath blight in China. In order to improve the phloem mobility of phenazine-1-carboxylic acid (PCA), four PCA derivatives were designed and synthesized by conjugating PCA with l-alanine methyl ester, d-alanine methyl ester, l-alanine and d-alanine respectively. In vitro and planta bioassays results showed that conjugates L-PAM and D-PAM exhibited higher fungicidal activities against Rhizoctonia solani Kuhn than PCA while L-PA and D-PA were less active than PCA. The concentration of conjugates in Ricinus communis phloem sap was determined by HPLC. The results showed that only L-PA exhibited phloem mobility among these conjugates, and its concentration in Ricinus communis phloem sap increased with the increase of time (the maximum concentration was 12.69MUM within 5h). However, the results of pot experiments showed that L-PA and other conjugates didn't exhibited the inhibition for the growth of Rhizoctonia solani Kuhn in the lower leaves after treatment in the upper leaves of rice seedlings. This may be due to the poor plant absorbility for them or their too little amount of accumulation in the lower leaves.

AB - The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Lividae) transmits the Candidatus Liberibacter asiaticus, which causes citrus greening disease or Huanglongbing, (HLB). To date, there is no efficient cure for HLB disease and the control of D. citri using insecticides became the most important tools for the management of HLB. However, the extensive use of insecticides could increase D. citri resistance to these insecticides. The objective of this study was to investigate the effect of RNA interference of acetylcholinesterase (AChE) on the mortality and susceptibility of D. citri to the four major insecticides used in Florida. In this study, we used a consensus sequence derived from the two AChE genes and cholinesterase 2-like (ChE-2-like) gene to target all of the three genes. Treatment with dsRNA-AChE increased the mortality percentages of both nymphs and adults of D. citri. The mortality percentage increased with the increase in the concentration of applied dsRNA-AChE, and the highest mortality (> 60%) was observed at the highest applied concentration (125ng/MUl). Treatments of nymphs or adults with dsRNA-AChE down-regulated the expression of the three targeted genes of D. citri. Silencing of AChE and ChE in D. citri nymphs increased the susceptibility of emerged adults to chlorpyrifos and carbaryl, which act as AChE inhibitors. However, treatment with dsRNA-AChE did not increase the susceptibility of emerged adults to imidacloprid, which acts as an agonist of nicotinic acetylcholine receptors. In the same manner, treatment of adults with dsRNA-AChE increased their susceptibility to chlorpyrifos and carbaryl, but did not affect their susceptibility to imidacloprid. The ANOVA did not show any significant increase in susceptibility of D. citri adults to fenpropathrin after treatment with dsRNA-AChE, either as nymphs or as adults. However, simple linear regression showed that treatment with dsRNA-AChE increased D. citri susceptibility to fenpropathrin, which indicated that AChE could be involved in the metabolism of fenpropathrin. Our results indicated that silencing of AChE and ChE genes in D. citri to increase its susceptibility to insecticides could be a promising tool for the control of this important vector. PMID- 29183616 TI - Characterization of a nicotinic acetylcholine receptor binding site for sulfoxaflor, a new sulfoximine insecticide for the control of sap-feeding insect pests. AB - Sulfoxaflor (SFX, IsoclastTM Active) is a recently developed sulfoximine insecticide that is highly effective against sap-feeding insect pests. SFX has been shown to act through an interaction with insect nicotinic acetylcholine receptors (nAChRs). SFX was previously found to interact weakly with the binding site for the neonicotinoid imidacloprid. However, radioligand displacement studies characterizing the binding site of the insecticide SFX itself have not been conducted. In this study, we report the characterization of a high affinity [3H]SFX Myzus persicae (green peach aphid, GPA) binding site with relatively low abundance. Through the evaluation of a set of SFX analogs, we have demonstrated that displacement of [3H]SFX shows an excellent correlation with GPA toxicity, and thus is toxicologically relevant. Comparison with the previously described methyl-SFX binding site information reveals differences with the SFX binding site that are discussed herein. [3H]SFX therefore represents a new tool for the characterization of insect nAChRs. PMID- 29183617 TI - Azadirachtin impact on mate choice, female sexual receptivity and male activity in Drosophila melanogaster (Diptera: Drosophilidae). AB - Azadirachtin, a neem compound (Azadirachta indica) with medical and anti-insect properties, is one the most successful botanical pesticides in agricultural use. However, its controversial impact on non-targeted species and its mechanism of action need to be clarified. In addition, Azadirachtin impact on pre- and post mating traits remains largely undocumented. The current study examined the effects of Azadirachtin on Drosophila melanogaster as a non-target and model species. Azadirachtin was applied topically at its LD50 (0.63MUg) on the day of adult emergence and its effect was evaluated on several traits of reproductive behavior: mate choice, male activity, female sexual receptivity, sperm storage and female sterility. In choice and no choice conditions, only male treatment reduced mating probability. Female treatment impaired mating probability only when males had the choice. Males' mating ability may have been impaired by an effect of the treatment on their mobility. Such an effect was observed in the actimeter, which revealed that treated males were less active than untreated ones, and this effect persisted over 8days. Azadirachtin treatment had, however, no effect on the nycthemeral rhythm of those males. Even when mating occurred, Azadirachtin treatment impaired post-mating responses especially when females or both sexes were treated: remating probability increases and female fertility (presence of larvae) decreases. No impairment was observed on the efficiency of mating, evaluated by the presence of sperm in the spermatheca or the ventral receptacle. Male treatment only had no significant effect on these post-mating responses. These findings provide clear evidence that Azadirachtin alters the reproductive behavior of both sexes in D. melanogaster via mating and post-mating processes. PMID- 29183618 TI - Encephalitis associated with antibodies against the NMDA receptor. AB - The encephalitis associated with antibodies against the N-methyl-D-aspartate receptor (NMDAR) is characterized by the presence of antibodies against the GluN1 subunit of this receptor, resulting in symptoms that are similar to those observed in models of genetic or pharmacologic reduction of NMDARs. Patients are usually young adults, predominantly women, and children who develop, in a sequential manner, rapidly progressive symptoms including psychosis, abnormal movements, autonomic dysfunction, and coma. Epileptic seizures are variable and can occur throughout the course of the disease. The disease is often mistaken as viral encephalitis, primary psychiatric disorders, drug abuse, or neuroleptic malignant syndrome. About 50% of young women have an ovarian teratoma; in young girls and men the presence of a tumour is infrequent. In some patients, the disease is triggered by herpes simplex encephalitis. The recognition of anti NMDAR encephalitis is important because, despite its severity, most patients respond to immunotherapy. PMID- 29183619 TI - Non-sustained microvolt level T-wave alternans in congenital long QT syndrome types 1 and 2. AB - BACKGROUND: Patients with long QT syndrome (LQTS) are predisposed to polymorphic ventricular tachycardia (VT) during adrenergic stimulation. Microvolt T-wave alternans (MTWA) is linked to vulnerability to VT in structural heart disease. The prevalence of non-sustained MTWA (NS-MTWA) in LQTS is unknown. METHODS: 31 LQT1, 42 LQT2, and 80 controls underwent MTWA testing during exercise. MTWA tests were classified per standardized criteria, and re-analyzed according to the modified criteria to account for NS-MTWA. RESULTS: LQT1 and LQT2 patients had a significantly higher frequency of late NS-MTWA (26% and 12%) compared to controls (0%). There was no significant difference between the groups with respect to sustained and early NS-MTWA. Late NS-MTWA was significantly associated with QTc. CONCLUSION: LQT1 and LQT2 patients had a higher prevalence of late NS-MTWA during exercise than matched controls. NS-MTWA likely reflects transient adrenergically mediated dispersion of repolarization, and could be a marker of arrhythmic risk in LQTS. PMID- 29183620 TI - Empowerment in Dermatology. AB - The term empowerment refers to any process that facilitates behavioral changes and encourages responsibility and making informed choices. The concept has been applied mainly to help patients with chronic conditions achieve therapeutic goals. The aim of the approach in health care is to enhance self-caring and self efficacy. The term derives from the English verb to empower meaning "to give (someone) the authority or power to do something" or "to make an individual or a group stronger or more powerful". One of the responsibilities of health professionals is to improve patients' knowledge and their ability to choose between the different alternatives available to them so that they can act accordingly. In this article, we review the various definitions of the term empowerment, the tools used to measure patient empowerment, the implications of the concept for the management of chronic disease, and its use in dermatological conditions. PMID- 29183621 TI - Capillary Malformations Treated With Sequential Pulsed Dye and Nd:YAG Laser Therapy: A Retrospective Study. AB - INTRODUCTION AND OBJECTIVE: Capillary malformations are the most common vascular malformations in childhood. The current treatment of choice is pulsed dye laser (PDL) therapy, but this frequently does not result in complete resolution. The search for alternative treatment strategies thus continues. In this study we describe our experience with the use of sequential dual-wavelength PDL and Nd:YAG laser therapy in patients with capillary malformations. MATERIAL AND METHODS: We conducted a retrospective, descriptive study of patients with capillary malformations treated with dual-wavelength PDL and Nd:YAG laser therapy between 2006 and 2011. Four dermatologists rated the effectiveness of treatment on a scale of 10 to 0. We also investigated the potential value of the following factors as predictors of better treatment response: sex, malformation size and color, and presence of associated hypertrophy. Adverse effects were also analyzed. RESULTS: We studied 71 patients and most of them experienced a statistically significant improvement after treatment. More favorable responses were observed for violaceous malformations, lesions with associated hypertrophy, and smaller lesions. Adverse effects were reported for 26.76% of patients, and the most common effect was the appearance of isolated areas of skin atrophy. CONCLUSIONS: We consider that sequential dual-wavelength PDL and ND:YAG laser therapy is an effective alternative for treating capillary malformations in selected patients.

PMID- 29183623 TI - Role of angiopoietin-like 3 (ANGPTL3) in regulating plasma level of low-density lipoprotein cholesterol. AB - BACKGROUND AND AIMS: Angiopoietin-like 3 (ANGPTL3) has emerged as a key regulator of lipoprotein metabolism in humans. Homozygous loss of ANGPTL3 function causes familial combined hypolipidemia characterized by low plasma levels of triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C). While known effects of ANGPTL3 in inhibiting lipoprotein lipase and endothelial lipase contribute to the low TG and HDL-C, respectively, the basis of low LDL-C remains unclear. Our aim was to explore the role of ANGPTL3 in modulating plasma LDL-C. METHODS: We performed RNAi-mediated gene silencing of ANGPTL3 in five mouse models and in human hepatoma cells. We validated results by deleting ANGPTL3 gene using the CRISPR/Cas9 genome editing system. RESULTS: RNAi-mediated Angptl3 silencing in mouse livers resulted in very low TG, HDL-C and LDL-C, a pattern similar to the human phenotype. The effect was observed in wild-type and obese mice, while in hCETP/apolipoprotein (Apo) B-100 double transgenic mice, the silencing decreased LDL-C and TG, but not HDL-C. In a humanized mouse model (Apobec1-/- carrying human ApoB-100 transgene) deficient in the LDL receptor (LDLR), Angptl3 silencing had minimum effect on LDL-C, suggesting the effect being linked to LDLR. This observation is supported by an additive effect on LDL-C between ANGPTL3 and PCSK9 siRNAs. ANGPTL3 gene deletion induced cellular long-chain TG and ApoB-100 accumulation with elevated LDLR and LDLR-related protein (LRP) 1 expression. Consistent with this, ANGPTL3 deficiency by gene deletion or silencing reduced nascent ApoB-100 secretion and increased LDL/VLDL uptake. CONCLUSIONS: Reduced secretion and increased uptake of ApoB containing lipoproteins may contribute to the low LDL-C observed in mice and humans with genetic ANGPTL3 deficiency.

PMID- 29183626 TI - Does nutritional intervention maintain its prognostic benefit in the long term for malnourished patients hospitalised for heart failure? AB - OBJECTIVE: To assess the long-term effect of nutritional intervention on malnourished, hospitalised patients with heart failure (HF). METHODS: A total of 120 malnourished patients hospitalized for HF were randomised to undergo (or not) an individual nutritional intervention for 6 months. The primary event was the combination of all-cause death and readmission for HF. We performed an intent-to treat analysis and assessed the effect of the intervention at 24 months. RESULTS: The combined event occurred in 47.5% of the intervention group and in 73.8% of the control group (hazard ratio: 0.45; 95% confidence interval: 0.28-0.72; P=.001). Thirty-nine percent of the intervention group and 59% of the control group died (hazard ratio: 0.53; 95% confidence interval: 0.31-0.89; P=.017). CONCLUSION: A nutritional intervention for malnourished patients hospitalised for HF maintains its prognostic benefit in the long-term follow-up.

AB - Fumaric acid ester-based drugs are used for the treatment of psoriasis and multiple sclerosis. All licensed fumaric acid ester drugs contain dimethylfumarate (DMF) as the main active component. Due to the expanding use of oral DMF there is growing scientific interest in determining its as-yet-unknown mechanism of action. However, the pharmacology and chemistry of DMF are often not fully considered in the design and interpretation of experiments; namely, that while DMF is plasma-membrane permeable and has strong effects on many cell types in vitro, it is rapidly metabolized into membrane-impermeable monomethylfumarate (MMF) in vivo. This can lead to significant biological effects being erroneously assigned to DMF. Understanding the pharmacology of DMF means that future work can more closely reflect the state in vivo. PMID- 29183629 TI - Is human papillomavirus genotype important in predicting disease progression in women with biopsy-proven negative or CIN1 of atypical squamous cell of undetermined significance (ASC-US) cytology? AB - OBJECTIVES: Our aim was to estimate the risk of disease incidence in women with atypical squamous cell of undetermined significance (ASC-US) without histology proven cervical intraepithelial neoplasia grade 2 or worse (CIN2+) by human papillomavirus (HPV) genotype. METHODS: Between January 2002 and September 2010, incidence of CIN2+ in 2880 women including 2172 with ASC-US and histology-proven negative and 708 with ASC-US with histology-proven CIN1 was investigated. Baseline HR-HPV status was determined by the hybrid capture II assay (HC2) and HR HPV genotype by the HPV DNA chip test (HDC). Cumulative incidence and hazard ratios were estimated to explore differences between index data and associations with CIN2+. RESULTS: Of the 2880 women, the HC2 was positive in 1509 women (52.4%) and the HDC was positive in 1563 women (54.3%). The overall agreement between the HDC and HC2 was 97.4%. One hundred ninety (6.6%) patients developed CIN2+. The 5-year cumulative incidence rate of CIN2+ in HPV-16, HPV-31, HPV-52, and HPV-58 were 16.7%, 15.1%, 12.6%, and 12.9%, respectively. On multivariate analysis, being positive in HPV-16 (hazards ratio [HR]=2.431; 95% CI, 1.789 3.332; P<0.01), HPV-31 (HR=2.335; 95% CI, 1.373-3.971; P<0.01), HPV-52 (HR=1.592; 95% CI, 1.031-2.458; P=0.03), and HPV-58 (HR=1.650; 95% CI, 1.132-2.407; P<0.01) were significantly associated with developing CIN2+ compared to being negative for that type. CONCLUSIONS: Among women with ASC-US, HPV-16, HPV-31, HPV-52, or HPV-58 positive women may need intensified follow-up as they have the highest risk of becoming CIN2+. PMID- 29183631 TI - Birth weight to placenta weight ratio and its relationship to ultrasonic measurements, maternal and neonatal morbidity: A prospective cohort study of nulliparous women. AB - INTRODUCTION: Birth weight to placenta weight (BWPW)-ratio is an indicator of the ability of the placenta to maintain adequate nutrient supply to the fetus. We sought to investigate the relationship between BWPW-ratio with fetal growth, utero-placental Doppler and neonatal and maternal morbidity. METHODS: We studied a group of 3311 women recruited to a prospective cohort study of nulliparous women (Rosie Hospital, Cambridge, UK) who delivered a live born infant at term and whose placental weight and birth weight were known. Ultrasonic indices and BWPW ratio were converted to gestational age adjusted z scores. Analysis of continuous variables was by multivariable linear regression. BWPW ratio was also categorized (lowest or highest quintile, both referent to quintiles 2 to 4) and associations with adverse outcomes analyzed using multivariable logistic regression. RESULTS: Lowest quintile of BWPW-ratio was associated (adjusted odds ratio [95% CI], P) with both neonatal morbidity (1.55 [1.12-2.14], 0.007) and maternal diabetes (1.75 [1.18-2.59], 0.005). Highest quintile of BWPW ratio was associated with a reduced risk of maternal obesity (0.71 [0.53 to 0.95], 0.02) and preeclampsia (0.51 [0.31 to 0.84], 0.008), but higher (adjusted z score [95% CI], P) uterine artery Doppler mean pulsatility index (PI) at 20 weeks of gestation (0.09 [0.01-0.18], 0.04) and umbilical artery Doppler PI at 36 weeks of gestation (0.16 [0.07-0.25], <0.001). CONCLUSION: BWPW-ratio is related to ultrasonic measurements and both neonatal and maternal morbidity. Therefore, this ratio may be an indicative marker of immediate and longer term health risks for an individual. PMID- 29183630 TI - Where, When, and How: Are they all sensorimotor? Towards a unified view of the dorsal pathway in vision and audition. AB - Dual processing streams in sensory systems have been postulated for a long time. Much experimental evidence has been accumulated from behavioral, neuropsychological, electrophysiological, neuroanatomical and neuroimaging work supporting the existence of largely segregated cortical pathways in both vision and audition. More recently, debate has returned to the question of overlap between these pathways and whether there aren't really more than two processing streams. The present piece defends the dual-system view. Focusing on the functions of the dorsal stream in the auditory and language system I try to reconcile the various models of Where, How and When into one coherent concept of sensorimotor integration. This framework incorporates principles of internal models in feedback control systems and is applicable to the visual system as well.

PMID- 29183634 TI - Group 6. Modalities and frequency of monitoring of patients with adrenal insufficiency. Patient education. AB - Patients with adrenal insufficiency require regular, specialised monitoring in order to optimise their replacement therapy, to detect signs of under- and over dosage, and to examine for possible associated disorders (auto-immune disorders in the case of auto-immune primary adrenal insufficiency either isolated or as part of auto-immune polyendocrinopathy syndrome type 1; illnesses with underlying monogenic causes). The transition period between adolescence and adulthood represents an added risk of a breakdown in monitoring which requires particular attention from medical teams and coordination between adult and pediatric medical teams. It is essential to encourage patient autonomy in the management of their illness, notably their participation in treatment education programs, in particular programs that target avoidance of, or early treatment of acute adrenal insufficiency. The principal educational objectives for patients in such programs are: to be in possession of, and carry the necessary tools for their treatment in an emergency; to be able to identify situations of increased risk and the early signs of adrenal crisis; to know how to adjust their oral glucocorticoid treatment; to be capable of administering hydrocortisone by subcutaneous injection; to be able to predict and therefore adjust treatment to different situations (heat, physical exercise, travel) and to be able to correctly use the appropriate resources of the healthcare services. Other programs could also be developed to respond to needs and expectations of patients, notably concerning the adjustment of hydrocortisone dosage to avoid overdose in the context of chronic fatigue syndrome. PMID- 29183635 TI - Hypothermia indices among severely injured trauma patients undergoing urgent surgery: A single-centred retrospective quality review and analysis. AB - BACKGROUND: Hypothermia (<36 degrees C) exacerbates trauma-induced coagulopathy and worsens morbidity and mortality among severely injured trauma patients; there is a paucity of published data describing how well trauma centres adhere to standards regarding measurement of temperature, and best practices for preventing and treating hypothermia. METHODS: We completed a retrospective quality audit of all severely injured trauma patients (Injury Severity Score (ISS>=20)) who had urgent surgery at Sunnybrook Health Sciences Centre (SHSC) between 2010 and 2014. Information regarding temperature monitoring was evaluated over the course of the initial resuscitation and admission. Independent risk factors for in-hospital mortality were elucidated through a multivariable regression analysis. RESULTS: Out of a total of 4492 trauma patients, 495 were severely-injured and went to the operating room (OPR) after being treated in the trauma bay (TB) at SHSC between 2010 and 2014. The majority of the patients were male (n=384, 77.6%) and had a blunt mechanism of injury (n=391, 79.0%). The median ISS score was 29 (interquartile range (IQR) 26, 35). Eighty-nine (17.9%) patients died; 26 (5.2%) of these patients died intra-operatively. Less than one fifth of patients (n=82,16.6%) received a temperature measurement during pre-hospital transport phase. Upon arrival to the TB, almost two-thirds (n=301, 60.8%) of patients had their temperature recorded and a similar proportion (n=175, 58.1%) of those patients were hypothermic (<36 degrees C). In the OPR, close to 80% (n=389, 78.6%) of patients had their temperature measured on both arrival; almost 60% (n=223, 57.3%) were hypothermic on arrival. Almost all patients had their temperature measured upon arrival to the ICU or specialized ward (n=450, 98.3%). Warming initiatives were documented in only 36 (7.3%) patients in the TB, yet documented in almost all patients in OR (n=464, 93.7%). An increased risk of in hospital mortality was correlated with not taking a temperature measurement in the TB (Odds Ratio (OR) 2.86 (95% Confidence Interval (CI) [1.64-4.99]) or OPR (OR 4.66 (95% CI [2.50-8.69]). CONCLUSIONS: A majority of severely injured trauma patients are hypothermic well into the perioperative period after initial admission. An absence of having temperature measurement during initial hospitalization is associated with increased in-hospital mortality amongst this patient group. Quality improvement initiatives should aim to strive for ongoing temperature measurement as a key performance indicator and early prevention and treatment of hypothermia during initial resuscitation.

PMID- 29183637 TI - Cell-spray auto-grafting technology for deep partial-thickness burns: Problems and solutions during clinical implementation. AB - Cell-spray autografting is an innovative early treatment option for deep partial thickness burn wounds. As an alternative to non-operative management, cell-spray autografting can achieve rapid wound re-epithelialization, particularly in large wounds. When compared to traditional mesh autografting for deep partial-thickness burn wounds, cell-spray autografting can accomplish re-epithelialization with a much smaller donor site. In this review, we describe the development of a biomedical engineering method for isolation and immediate distribution of autologous, non-cultured, adult epidermis-, and adult dermis-derived stem cells. We present data on cell isolation procedures in 44 patients with deep partial thickness burns performed over five years under an innovative practice IRB. Treated patients presented with a variety of burn wound etiologies and a wide range of TBSA. Overall clinical results were very satisfying. The average hospital length of stay following treatment was seven days. Over the time period, the donor-site to burn-wound surface area ratio was enhanced from 1:80 to 1:100. A detailed analysis of all process-related biotechnology and operative problems, pitfalls, and solutions was performed and is reported herein. Strategies for future clinical studies are discussed.

It is expected that the progressive aging of the population will have an unprecedented impact on the incidence of various tumours. In fact, the management of elderly cancer patients is already a major public health problem in developed countries. However, elderly patients have systematically been excluded from cancer drug studies or protocol development. This has left health professionals in uncharted territory, without proper tools to address the multiple difficulties that arise in the treatment of these patients. A comprehensive geriatric assessment may serve as an ideal tool for the correct detection of hidden problems, facilitating treatment decisions in these complex patients, and integrating the care of patients with comorbidities. PMID- 29183639 TI - Systematic review and meta-analysis of prognostic role of splenic vessels infiltration in resectable pancreatic cancer. AB - BACKGROUND: Identification of factors associated with dismal survival after surgery in resectable pancreatic ductal adenocarcinoma is important to select patients for neoadjuvant treatment. The present meta-analysis aimed to compare the results of distal pancreatectomy for resectable adenocarcinoma of the pancreatic body-tail with and without splenic vessels infiltration. METHODS: A systematic search was performed of PubMed, Embase and the Cochrane Library in accordance with PRISMA guidelines. The inclusion criteria were studies including patients who underwent distal pancreatectomy for pancreatic cancer with or without splenic vessels infiltration. 5-year overall survival (OS) was the primary outcomes. Meta-analysis was carried out applying time-to-event method. RESULTS: Six articles with 423 patients were analysed. Patients with pathological splenic artery invasion had a worse survival compared with those without infiltration (Hazard ratio 1.76, 95% CI 1.36-2.28; P < 0.0001). A similar results was found when considering pathological splenic vessels infiltration, showing that survival was significantly poorer when splenic vein infiltration was present (Hazard ratio 1.51, 95% CI 1.19-1.93; P = 0.0009). CONCLUSIONS: This meta analysis showed worse survival for patients with splenic vessels infiltration undergoing distal pancreatectomy for pancreatic cancer. Splenic vessels infiltration represents the stigmata of a more aggressive disease, although resectable.

METHODS: We retrospectively analysed prospectively collected data from 376 consecutive patients who underwent liver surgery for CLM between June 2010 and August 2015. We compared the outcomes of patients with right colon tumours and those with left colorectal tumours. The splenic flexure was used as the cut off point to determine the anatomic primary site. RESULTS: Among the 364 patients eligible, 74 (20.3%) had a right-sided primary tumour. These patients were older, had a poorer American Society of Anaesthesiologists status and had fewer node positive primary tumours. The CLM characteristics were similar between both groups. Median PFS was not significantly different between the two groups at 9.9 months, as well as the pattern of recurrence. Median OS was shorter for patients with right-sided primary tumour (34.6 versus 45.3 months, p = 0.035). Similar results were observed when patients with rectal tumour were excluded from analysis (34.6 vs. 47.5 months, p = 0.007). Primary tumour site was an independent prognosis factor in multivariate analysis. CONCLUSION: Right-sided location of the primary tumour is associated with worse OS after surgery for CLM, but seems to have no influence on PFS, and on the pattern of recurrence.

AB - Tick-borne diseases (TBDs) are emerging and reemerging diseases transmitted by ticks, which portray wide heterogeneity and global distribution. TBDs may present acute clinical pictures that resemble those of autoimmune diseases (i.e., musculoskeletal symptoms, cutaneous involvement, neurologic impairment, renal failure, etc.), and in some cases infection is considered a triggering factor for autoimmunity (e.g., rheumatoid arthritis, autoimmune thyroid disease, vasculitides). The clinician should consider TBDs among the differential diagnoses when approaching autoimmune-like signs in areas of tick infestation. Epidemiological setting (e.g., endemic areas, seasons) and an accurate diagnostic approach (i.e., clinical history, physical examination and laboratory tests) are necessary to confirm TBDs. Further, control and prevention of TBDs is warranted. Research in the fields of ticks microbiome and vaccination (i.e., wildlife and humans) are ahead to control vector transmission and bacterial infection. This review offers a comprehensive update on TBDs and their relationship with autoimmunity. PMID- 29183643 TI - Selective targeting of pro-inflammatory Th1 cells by microRNA-148a-specific antagomirs in vivo. AB - In T lymphocytes, expression of miR-148a is induced by T-bet and Twist1, and is specific for pro-inflammatory Th1 cells. In these cells, miR-148a inhibits the expression of the pro-apoptotic protein Bim and promotes their survival. Here we use sequence-specific cholesterol-modified oligonucleotides against miR-148a (antagomir-148a) for the selective elimination of pro-inflammatory Th1 cells in vivo. In the murine model of transfer colitis, antagomir-148a treatment reduced the number of pro-inflammatory Th1 cells in the colon of colitic mice by 50% and inhibited miR-148a expression by 71% in the remaining Th1 cells. Expression of Bim protein in colonic Th1 cells was increased. Antagomir-148a-mediated reduction of Th1 cells resulted in a significant amelioration of colitis. The effect of antagomir-148a was selective for chronic inflammation. Antigen-specific memory Th cells that were generated by an acute immune reaction to nitrophenylacetyl coupled chicken gamma globulin (NP-CGG) were not affected by treatment with antagomir-148a, both during the effector and the memory phase. In addition, antibody titers to NP-CGG were not altered. Thus, antagomir-148a might qualify as an effective drug to selectively deplete pro-inflammatory Th1 cells of chronic inflammation without affecting the protective immunological memory.

AB - OBJECTIVE: To explore children's' and families' experiences of using intensive care diaries after discharge and the role of diaries in the process of recovering from a stay in the paediatric intensive care unit. DESIGN AND SETTING: Qualitative, exploratory design. Data collection consisted of semi-structured interviews with five children and their families, conducted four to six months after discharge from the intensive care unit. Inclusion criteria were children and their families, with a stay for more than three days who had a diary written for them. Data were analysed using thematic analysis FINDINGS: Three main themes emerged: (i) value to the entire family, (ii) creating memories, (iii) the importance of pictures. CONCLUSION: Diaries were used after discharge as a support for both children and families and played a role in making the paediatric intensive care experience meaningful by providing explanations and coherence. The findings suggest that a diary can serve as a catalyst for the coping process of the family unit. Findings also confirm how the children's memories are characterised by a sense of unreality. The diary could thus help fill in some of the missing picture to support the children in understanding their story. PMID- 29183645 TI - Survivorship Analysis and Clinical Outcomes of Transtibial Pullout Repair for Medial Meniscus Posterior Root Tears: A 5- to 10-Year Follow-up Study. AB - PURPOSE: This study investigated the clinical outcomes and mid- to long-term survival rates in patients undergoing transtibial pullout repair of medial meniscus posterior root tears (MMPRTs) after a minimum follow-up of 5 years. METHODS: Between 2005 and 2011, patients with MMPRTs who had been followed for at least 5 years after undergoing transtibial pullout repair were recruited. Participants were identified using medical records and information in a prospectively collected database. Clinical outcomes were assessed based on a comparison of patient preoperative Lysholm scores and their scores at the final follow-up. A Kaplan-Meier survival analysis was used to investigate the survival rates of repair procedures. Clinical failures were defined as cases requiring conversion to total knee arthroplasty (TKA) or having final Lysholm score <65 or less than their preoperative scores. RESULTS: Overall, 91 patients (mean age, 58.7 +/- 9.7 years) were included: the mean follow-up duration was 84.8 +/- 13.8 months. Among these patients, the mean Lysholm score improved significantly from 51.8 +/- 7.9 preoperatively to 83.0 +/- 11.1 at the final follow-up (P < .001). Overall, 4 patients failed due to conversion to TKA (n = 1) or having final Lysholm scores <65 or less than the preoperative scores (n = 3). The overall Kaplan-Meier probabilities of survival after repair were 99% at 5 years, 98% at 6 years, 95% at 7 years, and 92% at 8 years. CONCLUSIONS: Among patients with MMPRTs, transtibial pullout repair demonstrated a high clinical survival rate and the patients demonstrated clinical improvement, based on mid- and long-term follow-up examinations. LEVEL OF EVIDENCE: Level IV, retrospective uncontrolled case series. PMID- 29183646 TI - A risk score to predict the absence of left ventricular reverse remodeling: Implications for the timing of ICD implantation in primary prevention. AB - BACKGROUND: A prophylactic implantable cardioverter defibrillator (ICD) in patients with heart failure and reduced left ventricular ejection fraction (HFrEF) is only indicated when left ventricular ejection fraction (LVEF) reassessment remains <=35% after 3-6 months on optimal pharmacological therapy. However, LVEF may not improve during this period and the patient may be exposed to an unnecessary risk of sudden cardiac death. This study aimed to determine the incidence and predictors of the absence of left ventricular reverse remodeling (LVRR) after pharmacological treatment optimization in patients with HFrEF to design a risk score of absence of LVRR. METHODS: Consecutive outpatients with LVEF <=35% were included in this observational prospective study. Up-titration of angiotensin-converting enzyme (ACE) inhibitors/angiotensin II receptor blockers (ARBs), beta-blockers, mineralocorticoid receptor antagonists (MRAs), and ivabradine was performed in our Heart Failure (HF) Unit. The absence of LVRR was defined as the persistence of an LVEF <=35% at the 6-month follow-up. RESULTS: One hundred and twenty patients were included. At the 6-month follow-up, 64%, 76%, 72%, and 7% of patients were at 100% of the target dose of ACE inhibitors/ARBs, beta-blockers, MRAs, and ivabradine, respectively. LVRR was observed in 48% of the patients. Ischemic cardiomyopathy, prolonged HF duration, and larger left ventricular end-diastolic diameter index (LVEDDI) were independent predictors of the absence of LVRR. The risk score based on these predictors showed a c-statistic value of 0.81. CONCLUSIONS: Pharmacological treatment optimization is associated with LVRR in approximately half of cases, reducing potential ICD indications in parallel. However, ischemic cardiomyopathy, prolonged HF duration, and larger LVEDDI predict the absence of LVRR and favor ICD implantation without delay. The risk score based on the former predictors may help the clinician with the timing of ICD implantation. PMID- 29183647 TI - In-vitro digestion of curcumin loaded chitosan-coated liposomes. AB - Liposomes are considered a major route for encapsulation of hydrophilic and hydrophobic molecules. Chitosan coated liposomes could represent an alternative way as a carrier for delivery of drugs in human body. In this study the preparation and applicability of chitosan-coated liposomes containing curcumin as well as curcumin loaded anionic liposomes were evaluated. The applicability of the carriers was tested by means of an in-vitro digestion procedure allowing for measurement of the bioaccessibility of ingested curcumin. Values of diameter, polydispersity index and surface charge for curcumin loaded anionic liposomes obtained through dynamic light scattering and zeta-potential measurements were 129nm, 0.095 and -49mV, respectively. After chitosan-coating, diameter and polydispersity index remain unvaried while the surface charge gets positive. Slightly higher curcumin concentrations were found after the mouth and the stomach digestion phases when curcumin was loaded in anionic liposomes. On the contrary, after the intestinal phase, a higher percentage of curcumin was found when chitosan-coated liposomes were used as carrier, both in the raw digesta and in the bile salt micellar phase. It was shown that the presence of a positively charged surface allows a better absorption of curcumin in the small intestine phase, which increases the overall curcumin bioavailability. The mechanism behind these results can be understood from the composition of the different environments generated by the digestive fluids that differently interact with anionic or cationic surfaces.

PMID- 29183649 TI - A happiness degree predictor using the conceptual data structure for deep learning architectures. AB - BACKGROUND AND OBJECTIVE: Happiness is a universal fundamental human goal. Since the emergence of Positive Psychology, a major focus in psychological research has been to study the role of certain factors in the prediction of happiness. The conventional methodologies are based on linear relationships, such as the commonly used Multivariate Linear Regression (MLR), which may suffer from the lack of representative capacity to the varied psychological features. Using Deep Neural Networks (DNN), we define a Happiness Degree Predictor (H-DP) based on the answers to five psychometric standardized questionnaires. METHODS: A Data Structure driven architecture for DNNs (D-SDNN) is proposed for defining a HDP in which the network architecture enables the conceptual interpretation of psychological factors associated to happiness. Four different neural network configurations have been tested, varying the number of neurons and the presence or absence of bias in the hidden layers. Two metrics for evaluating the influence of conceptual dimensions have been defined and computed: one quantifies the influence weight of the conceptual dimension in absolute terms and the other one pinpoints the direction (positive or negative) of the influence. MATERIALS: A cross-sectional survey targeting non-institutionalized adult population residing in Spain was completed by 823 cases. The total of 111 elements of the survey are grouped by socio-demographic data and by five psychometric scales (Brief COPE Inventory, EPQR-A, GHQ-28, MOS-SSS and SDHS) measuring several psychological factors acting one as the outcome (SDHS) and the four others as predictors. RESULTS: Our D-SDNN approach provided a better outcome (MSE: 1.46.10-2) than MLR (MSE: 2.30.10-2), hence improving by 37% the predictive accuracy, and allowing to simulate the conceptual structure. CONCLUSIONS: We observe a better performance of Deep Neural Networks (DNN) with respect to traditional methodologies. This demonstrates its capability to capture the conceptual structure for predicting happiness degree through psychological variables assessed by standardized questionnaires. It also permits to estimate the influence of each factor on the outcome without assuming a linear relationship. PMID- 29183650 TI - Insights to bioprocess and treatment competence of urban wetlands. AB - Wetlands play a major role in the recharge of groundwater resources, maintenance of water quality (remediation), moderate microclimate while supporting local livelihood through provision of fish, fodder, etc. The present study aims to investigate algal-bacterial consortium as a function of residence time with the water quality dynamics in two major wetlands in Bangalore city, India. Over thirty-two genera of algae were recorded with more than 40 species in the lakes and two dominant bacterial assemblages. The higher Ammonium-N content favoured the growth of these members. Significant correlation was observed between the nutrient concentrations and the community structure at the inflows and the outflows. The algal community showed negative correlation to filterable COD and high nutrients levels while bacterial abundance was observed under high loadings. The green algae Chlorophyceae (Chlorella blooms), which are indicators of nutrient enrichment were observed predominantly, that needs an immediate attention. Higher overall treatment efficiency was observed in terms of CNP removal during the Pre-monsoon season attributed to absence of macrophytes cover and rapid growth of algal assemblage's due to higher temperature regimes with adequate solar insolation.

PMID- 29183653 TI - Chimeric mice with humanized liver: Application in drug metabolism and pharmacokinetics studies for drug discovery. AB - Predicting human drug metabolism and pharmacokinetics (PK) is key to drug discovery. In particular, it is important to predict human PK, metabolite profiles and drug-drug interactions (DDIs). Various methods have been used for such predictions, including in vitro metabolic studies using human biological samples, such as hepatic microsomes and hepatocytes, and in vivo studies using experimental animals. However, prediction studies using these methods are often inconclusive due to discrepancies between in vitro and in vivo results, and interspecies differences in drug metabolism. Further, the prediction methods have changed from qualitative to quantitative to solve these issues. Chimeric mice with humanized liver have been developed, in which mouse liver cells are mostly replaced with human hepatocytes. Since human drug metabolizing enzymes are expressed in the liver of these mice, they are regarded as suitable models for mimicking the drug metabolism and PK observed in humans; therefore, these mice are useful for predicting human drug metabolism and PK. In this review, we discuss the current state, issues, and future directions of predicting human drug metabolism and PK using chimeric mice with humanized liver in drug discovery. PMID- 29183654 TI - [Safety of SGLT2 inhibitors. A review of the adverse drug reactions registered in a national database]. AB - OBJECTIVE: To analyse the adverse drug reactions (ADRs) caused by Sodium-glucose Cotransporter-2 Inhibitors (SGLT2i) notified in Spain since they have been on the market. MATERIAL AND METHODS: An analysis was made of all the notifications registered in the Spanish Pharmacovigilance System of drugs for human use, arising from the use of SGLT2i. RESULTS: A total of 311 notifications were recorded, of which 169 (54.34%) were related to dapagliflozin, 81 (26.05%) to empagliflozin, and 61 (19.61%) to canagliflozin. There was a ratio of 52.1% women to 47.9% men. The mean age was 62.07+/-12.17years. There were 167 (53.7%) notifications were classified as non-serious and 144 (46.3%) as serious. A total of 534 ADRs were notified, with the most common being urinary tract infections in 37 (6.9%) cases, diabetic ketoacidosis in 30 (5.6%), balanoposthitis in 24 (4.5%), ketoacidosis in 16 (3%), vulvovaginal candidiasis in 16 (3%), dizzy spells in 11 (2.1%), and 10 (1.9%) with dysuria, Candida balanitis, and vulvovaginal pruritus. As regards the outcomes of the 534 ADRs, 55.6% recovered with no sequelae, with 14% still recovering, 4.9% not recovered, fatal in 1.1%, and unknown in 24.3%. CONCLUSIONS: The majority of the ADRs notified are infections of the urogenital tract, ketoacidosis, and kidney damage. Although the majority of the former were not serious, the ketoacidosis and kidney damage were, leading to hospital admission and being life threatening in some patients. For these reasons, it is recommended that they are, prescribed with caution, the warnings published by the health authorities consulted, as well as notify any ADR that is suspected in this therapeutic group, in order to improve and provide us with further knowledge. PMID- 29183656 TI - Plasma metabolomics reveal the correlation of metabolic pathways and Prakritis of humans. AB - BACKGROUND: Ayurveda, an ancient Indian medicinal system, has categorized human body constitutions in three broad constitutional types (prakritis) i.e. Vata, Pitta and Kapha. OBJECTIVES: Analysis of plasma metabolites and related pathways to classify Prakriti specific dominant marker metabolites and metabolic pathways. MATERIALS AND METHODS: 38 healthy male individuals were assessed for dominant Prakritis and their fasting blood samples were collected. The processed plasma samples were subjected to rapid resolution liquid chromatography-electrospray ionization-quadrupole time of flight mass spectrometry (RRLC-ESI-QTOFMS). Mass profiles were aligned and subjected to multivariate analysis. RESULTS: Partial least square discriminant analysis (PLS-DA) model showed 97.87% recognition capability. List of PLS-DA metabolites was subjected to permutative Benjamini Hochberg false discovery rate (FDR) correction and final list of 76 metabolites with p < 0.05 and fold-change > 2.0 was identified. Pathway analysis using metascape and JEPETTO plugins in Cytoscape revealed that steroidal hormone biosynthesis, amino acid, and arachidonic acid metabolism are major pathways varying with different constitution. Biological Go processes analysis showed that aromatic amino acids, sphingolipids, and pyrimidine nucleotides metabolic processes were dominant in kapha type of body constitution. Fat soluble vitamins, cellular amino acid, and androgen biosynthesis process along with branched chain amino acid and glycerolipid catabolic processes were dominant in pitta type individuals. Vata Prakriti was found to have dominant catecholamine, arachidonic acid and hydrogen peroxide metabolomics processes. CONCLUSION: The neurotransmission and oxidative stress in vata, BCAA catabolic, androgen, xenobiotics metabolic processes in pitta, and aromatic amino acids, sphingolipid, and pyrimidine metabolic process in kapha Prakriti were the dominant marker pathways.

AB - The ability to accurately predict violence and other forms of serious antisocial behavior would provide important societal benefits, and there is substantial enthusiasm for the potential predictive accuracy of neuroimaging techniques. Here, we review the current status of violence prediction using actuarial and clinical methods, and assess the current state of neuroprediction. We then outline several questions that need to be addressed by future studies of neuroprediction if neuroimaging and other neuroscientific markers are to be successfully translated into public policy. PMID- 29183657 TI - Predictive multiscale computational model of shoe-floor coefficient of friction. AB - Understanding the frictional interactions between the shoe and floor during walking is critical to prevention of slips and falls, particularly when contaminants are present. A multiscale finite element model of shoe-floor contaminant friction was developed that takes into account the surface and material characteristics of the shoe and flooring in microscopic and macroscopic scales. The model calculates shoe-floor coefficient of friction (COF) in boundary lubrication regime where effects of adhesion friction and hydrodynamic pressures are negligible. The validity of model outputs was assessed by comparing model predictions to the experimental results from mechanical COF testing. The multiscale model estimates were linearly related to the experimental results (p < 0.0001). The model predicted 73% of variability in experimentally-measured shoe floor-contaminant COF. The results demonstrate the potential of multiscale finite element modeling in aiding slip-resistant shoe and flooring design and reducing slip and fall injuries. PMID- 29183658 TI - Value of oxyneurography, based on near infrared spectroscopy, in the diagnosis of carpal tunnel syndrome in comparison to provocative clinical diagnostic tests and nerve conduction studies. AB - OBJECTIVE: Evaluation of the diagnostic utility of the oxyneurography (ONG) in diagnosing carpal tunnel syndrome (CTS). METHODS: ONG examination of the median nerve was performed in 260 patients. The results were compared with nerve conduction studies and clinical provocative tests. RESULTS: ONG index greater than or equal to 62% was found in 95.18% of the patients with no or minimal Nerve Conduction Study (NCS) changes (1-2 according to the Padua classification) but only in 1.69% of the patients with advanced NCS changes (Padua 3-6). The sensitivity and specificity of the ONG study i.e. 95.18% and 98.31%, respectively, were compared with standard clinical tests: Tinel sign (61.45% and 14.69%), Phalen test (34.94% and 45.20%), reverse Phalen test (81.93% and 34.46%) and carpal compression test (91.57% and 72.32%). CONCLUSIONS: ONG index lower than 62% was indicative of CTS. ONG has higher sensitivity and specificity then other clinical tests and it is an accurate and reliable method for the diagnosis of CTS. SIGNIFICANCE: Oxyneurography is a non-invasive, fast and safe study which may play role in the diagnosis of carpal tunnel syndrome. PMID- 29183659 TI - Are there gender differences in those diagnosed with psychogenic nonepileptic seizures? AB - OBJECTIVE: The objective of the study was to determine whether male and female populations of patients with psychogenic nonepileptic seizures (PNES) differ, in terms of demographic, social/clinical, and etiological factors as well as psychological measures. BACKGROUND: Psychogenic nonepileptic seizures are overrepresented by females; therefore, information about PNES in males is limited. Only a handful of studies have examined PNES and gender, and of those, one was a literature review and with the exception of two, most have had small sample sizes. Of the existing literature, differences in abuse type, psychiatric diagnoses, and psychometric results have been observed in the two genders. METHODS: This is a retrospective study of 51 consecutive males and 97 consecutive females with video-electroencephalogram (video-EEG) confirmed diagnosis of PNES. Patients were examined on demographics (age, education, working status), clinical (seizure frequency, trauma type: sexual, nonsexual, age of first trauma), and psychometric measures. The latter included the State Trait Anger Expression Inventory-2 (STAXI-2), Trauma Symptom Inventory-2 (TSI-2), the Coping Inventory for Stressful Situations (CISS), and the Quality of Life Inventory in Epilepsy-31 (QOLIE-31). RESULTS: Women reported experiencing significantly more sexual traumas (p=0.007) than men. Women also endorsed significantly higher levels of dissociation (p=0.012) and sexual disturbances (p=0.46). In contrast, men reported significantly greater use of avoidance (p=0.001) as a stress coping strategy and higher levels of depression (p=0.006). CONCLUSIONS: Gender differences were identified with males reporting a significantly higher use of avoidance (cognitive and behavioral avoidance of stress) and depressive symptoms. Women exhibited significantly higher rates of sexual trauma compared with male counterparts. Consequently, women also had significantly higher rates of trauma symptomatology (dissociation and sexual disturbances) which are often observed in those who have been traumatized sexually. These gender distinctions may support different first-line treatment approaches (e.g., trauma-focused; more traditional cognitive behavioral therapy) depending on the most prominent symptomatology. PMID- 29183660 TI - Comparison of the sedative effects of nalbuphine and butorphanol, alone or in combination with acepromazine in dogs. AB - OBJECTIVE: To compare sedation and effects on heart rate (HR), mean arterial pressure (MAP) and respiratory rate (fR) of nalbuphine and butorphanol, alone or combined with acepromazine in dogs. STUDY DESIGN: Prospective, randomized experimental trial. ANIMALS: Eight healthy Beagle dogs, aged (mean +/- standard deviation) 3.4 +/- 0.5 years and weighing 11.0 +/- 1.3 kg. METHODS: Each dog was treated four times: physiological saline (1 mL) combined with nalbuphine (0.5 mg kg-1; SAL-NAL) or butorphanol (0.15 mg kg-1; SAL-BUT), and acepromazine (0.05 mg kg-1) combined with nalbuphine (0.5 mg kg-1; ACP-NAL) or butorphanol (0.15 mg kg 1; ACP-BUT), intravenously (IV). The degree of sedation, assessed by a numeric descriptive scale (NDS) and simple numerical scale (SNS), HR, MAP, fR and rectal temperature (RT), were recorded before and 20 minutes after administration of saline or acepromazine, then 15, 30, 60, 90 and 120 minutes after nalbuphine or butorphanol. Values were compared with baseline and among treatments. RESULTS: Mild sedation was recorded for SAL-NAL and SAL-BUT, and moderate sedation for ACP NAL and ACP-BUT. NDS and SNS scores were higher for SAL-BUT and ACP-BUT at some time points when compared with SAL-NAL and ACP-NAL, respectively (p < 0.001). HR was lower in ACP-NAL than in ACP-BUT at 120 minutes and fR was lower in SAL-BUT than in SAL-NAL at 30 and 120 minutes (p < 0.05). RT was lower in SAL-BUT (37.5 +/- 0.5 degrees C) compared with SAL-NAL (38.0 +/- 0.5 degrees C) at 60-120 minutes (p < 0.05). CONCLUSIONS AND CLINICAL RELEVANCE: Butorphanol promoted a higher sedative effect than nalbuphine when alone and combined with acepromazine. IV administration of nalbuphine or butorphanol, with or without acepromazine, at the doses studied, resulted in minimal decreases in MAP, HR, fR and RT. PMID- 29183661 TI - Design, synthesis and evaluation against Mycobacterium tuberculosis of azole piperazine derivatives as dicyclotyrosine (cYY) mimics. AB - Three series of azole piperazine derivatives that mimic dicyclotyrosine (cYY), the natural substrate of the essential Mycobacterium tuberculosis cytochrome P450 CYP121A1, were prepared and evaluated for binding affinity and inhibitory activity (MIC) against M. tuberculosis. Series A replaces one phenol group of cYY with a C3-imidazole moiety, series B includes a keto group on the hydrocarbon chain preceding the series A imidazole, whilst series C explores replacing the keto group of the piperidone ring of cYY with a CH2-imidazole or CH2-triazole moiety to enhance binding interaction with the heme of CYP121A1. The series displayed moderate to weak type II binding affinity for CYP121A1, with the exception of series B 10a, which displayed mixed type I binding. Of the three series, series C imidazole derivatives showed the best, although modest, inhibitory activity against M. tuberculosis (17d MIC = 12.5 MUg/mL, 17a 50 MUg/mL). Crystal structures were determined for CYP121A1 bound to series A compounds 6a and 6b that show the imidazole groups positioned directly above the haem iron with binding between the haem iron and imidazole nitrogen of both compounds at a distance of 2.2 A. A model generated from a 1.5 A crystal structure of CYP121A1 in complex with compound 10a showed different binding modes in agreement with the heterogeneous binding observed. Although the crystal structures of 6a and 6b would indicate binding with CYP121A1, the binding assays themselves did not allow confirmation of CYP121A1 as the target. PMID- 29183662 TI - Bisindolylmethane thiosemicarbazides as potential inhibitors of urease: Synthesis and molecular modeling studies. AB - Bisindolylmethane thiosemicarbazides 1-18 were synthesized, characterized by 1H NMR and ESI MS and evaluated for urease inhibitory potential. All analogs showed outstanding urease inhibitory potentials with IC50 values ranging between 0.14 +/ 0.01 to 18.50 +/- 0.90 MUM when compared with the standard inhibitor thiourea having IC50 value 21.25 +/- 0.90 MUM. Among the series, analog 9 (0.14 +/- 0.01 MUM) with di-chloro substitution on phenyl ring was identified as the most potent inhibitor of urease. The structure activity relationship has been also established on the basis of binding interactions of the active analogs. These binding interactions were identified by molecular docking studies.

AB - INTRODUCTION: We found midline epithelial adhesions in the glandar urethral plate in patients with hypospadias. After dissolution, a blind epithelized channel becomes visualized inside of the plate pointing to immature embryonic luminization. In addition it reveals that the epithelized surface of the distal urethral plate is larger than previously considered. OBJECTIVE: To determine the incidence and extent of these new anatomical details of urethral plate in hypospadias patients. METHODS: We prospectively assessed the detailed anatomy of the urethral plate in 72 consecutive patients with hypospadias. We recorded the presence of adhesions in the middle of the glandar urethral groove that can be easily dissoluted (dissolution line - D-line). We recorded the plate width before and after D-line dissolution, the presence of the hidden blind channel at continuation of D-line (channel type-A) and of the visible blind channel between D-line and urethral hypospadiac meatus (type-B) (Figure). In 62 patients, where the urethral plate tubularization was considered (Duplay, TIP), septs between channels were opened in the midline and a final width of the plate was measured by rolling the plate around a tube. RESULTS: Midline adhesions (D-line) were found in all 72 patients. Mean length of D-line was 5.13 +/- O.17 mm. Mean plate width before dissolution was 5.9 +/- 0.15 mm, and after dissolution 7.8 +/- 0.16 mm. A blind channel of type A was detected in 22 patients (31%), type B in 24 (33%), type A and B in 16 (22%), and none in 10 patients (14%). Mean final plate width after D-line dissolution and opening of septs between channels in 62 patients with urethral plate tubularization was 8.7 +/- 0.15 mm. DISCUSSION: The main contribution of our study is a new perspective of distal urethral plate anatomy that enables enlargement of the epithelized surface of the distal urethral plate by dissolution of the preexisting epithelized groove and opening of epithelized channels within the plate. To the best of our knowledge, this anatomical anomaly has not been described previously. CONCLUSIONS: The distal urethral plate of all hypospadias patients is partially "folded" in the midline by epithelial adhesions of different depth and extent that may be easily dissoluted. In half of the patients (53%) the "folded" part of the plate continues proximally as a blind channel inside the urethral plate (type A channel). Opening of these structures together with the well-known urethral plate pits (type B channel) helps augment the width and the overall epithelized surface of the distal urethral plate. PMID- 29183665 TI - Stereochemical Divergence of Polyprenol Phosphate Glycosyltransferases. AB - In the three domains of life, lipid-linked glycans contribute to various cellular processes ranging from protein glycosylation to glycosylphosphatidylinositol anchor biosynthesis to peptidoglycan assembly. In generating many of these glycoconjugates, phosphorylated polyprenol-based lipids are charged with single sugars by polyprenol phosphate glycosyltransferases. The resultant substrates serve as glycosyltransferase donors, complementing the more common nucleoside diphosphate sugars. It had been accepted that these polyprenol phosphate glycosyltransferases acted similarly, given their considerable sequence homology. Recent findings, however, suggest that matters may not be so simple. In this Opinion we propose that the stereochemistry of sugar addition by polyprenol phosphate glycosyltransferases is not conserved across evolution, even though the GT-A fold that characterizes such enzymes is omnipresent. PMID- 29183666 TI - Microembolism of single cortical arterioles can induce spreading depression and ischemic injury; a potential trigger for migraine and related MRI lesions. AB - Increasing epidemiological evidence suggests an association between migraine with aura (MA) and cardiovascular events. There is experimental as well as clinical evidence implying cerebral microembolism as a potential trigger for MA attacks. Microembolism may also account for some of the ischemic MRI lesions more commonly observed in MA than in general population. Limited size of clinically-silent MRI lesions suggests isolated occlusion of a small vessel. However, it is not known whether selective thrombosis of a small arteriole (e.g. single mouse penetrating arteriole - PA), can induce cortical spreading depression (CSD), the putative cause of migraine aura and, hence, trigger an MA attack. For this, we mimiced thrombosis of a small vessel caused by microembolism by selectively occluding a PA just before diving into the cortex (radius; 10-25 um) in the mouse. Clotting was induced with FeCl3 applied focally over the PA by a glass micropipette for 3 min. DC potential changes were recorded and the alterations in cortical blood flow were monitored by laser speckle contrast imaging. Mice were kept alive for 1 4 weeks and brain sections were stained with H&E or luxol-fast blue to evaluate changes induced by PA occlusion. We found that single PA occlusion consistently triggered a CSD originating from the tissue around the PA soon after occlusion and induced delayed, small ischemic lesions within territory of the affected vessel a few weeks later. These findings suggest that cerebral microembolism can lead to MA attacks and may account for some of the silent brain lesions.

AB - BACKGROUND: Early identification of acute pancreatitis (AP) patients at high-risk of developing persistent organ failure (persistent OF) is a vital clinical goal. This research intends to assess the ability of apolipoprotein A-I (APO A-I) and high-density lipoprotein cholesterol (HDL-C) to predict persistent OF. METHODS: Between January 2011 and September 2016, a total of 102 adult AP patients with organ failure, local complications or deterioration of former comorbidities disease during hospitalization were included in this study retrospectively. Serum lipids were tested and computed the correlation with clinical outcomes or scoring systems. The AUCs to predict persistent OF were also calculated and compared with each other. RESULTS: Serum APO A-I and HDL-C levels were negatively associated with scoring systems. Meanwhile, serum lipids were negatively correlated with poor clinical outcomes. The AUCs of APO A-I, HDL-C, the combination of APO A-I and BISAP, or the combination of APO A-I and MCTSI to predict persistent OF among Moderately severe acute pancreatitis (MSAP) and Severe acute pancreatitis (SAP) patients were 0.886, 0.811, 0.912, and 0.900 or among those with organ failure were 0.915, 0.859, 0.933, and 0.933, respectively. CONCLUSIONS: The concentrations of APO A-I, HDL-C, and the combinations of APO A-I and scoring systems have high predictive value to predict persistent OF.

AB - In this work, a novel core-shell magnetic molecularly imprinted polymers (MMIPs) for the measurement of L-Hydroxyproline (Hyp) in dairy products was prepared. The derivative of Hyp using N-hydroxysuccinimidyl rhodamine B ester (RBS) as derivatization reagent was employed as template to prepare RBS-Hyp-MMIPs (Fe3O4@MIPs for RBS-Hyp). A new analytical procedure of in situ derivatization with MMIPs (ISD-MMIPs) has been developed for the specific extraction and determination of Hyp in dairy products by ultra high performance liquid chromatography tandem mass spectrometry. The RBS-Hyp-MMIPs was characterized by fourier transform infrared spectrometer and transmission electron microscopy, and evaluated by adsorption experiments. The adsorption process followed Langumuir adsorption isotherm with maximum adsorption capacity of RBS-Hyp on RBS-Hyp-MMIPs at 96 mg/g. In addition, RBS-Hyp-MMIPs showed a short equilibrium time (15.0 min), rapid magnetic separation (5 s) and high stability (retained 95.3% after six cycles). Under the optimized conditions, good linearity was observed with the limits of detection (S/N > 3) and limits of quantification (S/N > 10) at 0.1 and 0.5 ng/mL, respectively. On account of the specific extraction performance of RBS Hyp-MMIPs, not any interference peak from real sample matrix was observed in the chromatograms of milk powder, liquid milk and milk drink. The proposed procedure was successfully applied for selective determination of Hyp from dairy products with satisfactory validation results, which is of great significance to food safety. PMID- 29183669 TI - Quantification of more than 150 micropollutants including transformation products in aqueous samples by liquid chromatography-tandem mass spectrometry using scheduled multiple reaction monitoring. AB - A direct injection, multi residue analytical method separated in two chromatographic runs was developed utilizing scheduled analysis to simultaneously quantify 154 compounds, 84 precursors and 70 transformation products (TPs)/metabolites. Improvements in the chromatographic data quality, sensitivity and reproducibility were achieved by scheduling the analysis of each analyte into pre-determined retention time windows. This study shows the influence of the scan time on the dwell time and the number of data points per peak as well as the effect on the precision of analysis. Lowering the scan time decreased dwell time to a minimal value, however, this had no negative effects on the precision. Increasing the number of data points per peak by decreasing the scan time led to more accurate peak shapes. A final set of parameters was chosen to obtain a minimum of 10 data points per peak to guarantee accurate peak shapes and thus reproducibility of analysis. A validation of the method was performed for different water matrices yielding very good linearity for all substances, with limits of quantification mainly in the lower to mid ng/L-range and recoveries mainly between 70 and 125% for surface water, bank filtrate as well as influents and effluents of wastewater treatment plants. The analysis of environmental samples and wastewater revealed the occurrence of selected precursors and TPs in all analyzed matrices: 95% of the compounds in the target list could be quantified in at least one sample. The relevance of TPs and metabolites such as valsartan acid and clopidogrel acid was also confirmed by their detection in all aqueous matrices. Wastewater indicators such as acesulfame and diclofenac were detected at elevated concentrations as well as substances such as oxipurinol which so far were not in the focus of monitoring programs. The developed method can be used for rapid analysis of various water matrices without any sample enrichment and can aid the assessment of water quality and water treatment processes. PMID- 29183670 TI - Using glass-graded zirconia to increase delamination growth resistance in porcelain/zirconia dental structures. AB - OBJECTIVE: Porcelain fused to zirconia (PFZ) restorations are widely used in prosthetic dentistry. However, their tendency to delaminate along the P/Z interface remains a practical problem so that assessing and improving the interfacial strength are important design aspects. This work examines the effect of modifying the zirconia veneering surface with an in-house felspathic glass on the interfacial fracture resistance of fused P/Z. METHODS: Three material systems are studied: porcelain fused to zirconia (control) and porcelain fused to glass graded zirconia with and without the presence of a glass interlayer. The specimens were loaded in a four-point-bend fixture with the porcelain veneer in tension. The evolution of damage is followed with the aid of a video camera. The interfacial fracture energy GC was determined with the aid of a FEA, taking into account the stress shielding effects due to the presence of adjacent channel cracks. RESULTS: Similarly to a previous study on PFZ specimens, the fracture sequence consisted of unstable growth of channel cracks in the veneer followed by stable cracking along the P/Z interface. However, the value of GC for the graded zirconia was approximately 3 times that of the control zirconia, which is due to the good adhesion between porcelain and the glass network structure on the zirconia surface. SIGNIFICANCE: Combined with its improved bonding to resin-based cements, increased resistance to surface damage and good esthetic quality, graded zirconia emerges as a viable material concept for dental restorations. PMID- 29183671 TI - Effect of titania content and biomimetic coating on the mechanical properties of the Y-TZP/TiO2 composite. AB - OBJECTIVE: To investigate the effect of titania addition (0, 10 and 30mol%) on the microstructure, relative density, Young's modulus (E), Poisson's ratio (upsilon), mechanical properties (flexural strength, sigmaf, and Weibull modulus, m) of a Y-TZP/TiO2 composite. The effect of the presence of a biomimetic coating on the microstructure and mechanical properties was also evaluated. METHODS: Y TZP (3mol% of yttria) and Y-TZP/TiO2 composite (10 or 30mol% of titania) were synthesized by co-precipitation. The powders were pressed and sintered at 1400 degrees C/2h. The surfaces, with and without biomimetic coating, were characterized by X-ray diffraction analysis and scanning electron microscopy. The relative density was measured by the Archimedes' principle. E and upsilon were measured by ultrasonic pulse-echo method. For the mechanical properties the specimens (n=30 for each group) were tested in a universal testing machine. RESULTS: Titania addition increased the grain size of the composite and caused a significant decrease in the flexural strength (in MPa, control 815.4a; T10 455.7b and T30 336.0c), E (in GPa, control 213.4a; T10 155.8b and T30 134.0c) and relative density (control 99.0%a; T10 94.4%c and T30 96.3%b) of the Y-TZP/TiO2 composite. The presence of 30% titania caused substantial increase in m and upsilon. Biomimetic coating did not affect the mechanical properties of the composite. SIGNIFICANCE: The Y-TZP/TiO2 composite coated with a layer of CaP has great potential to be used as implant material. Although addition of titania affected the properties of the composite, the application of a biomimetic coating did not jeopardize its reliability. PMID- 29183672 TI - Bisphenol A release from an orthodontic resin composite: A GC/MS and LC/MS study. AB - OBJECTIVES: First, to analyse the in vitro release of BPA and Bis-GMA from an orthodontic resin composite (Transbond XT, 3M Unitek), stored in various conditions, by gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS); then to extrapolate the data to the clinical situation. Secondly, to explore the thermal stability of Bis-GMA. METHODS: Cylinders of resin composite were prepared and stored according to 3 different protocols: (1) they were light-cured 20s, then placed in artificial saliva; (2) they were light-cured 2s, then placed in acetonitrile; (3) they were light-cured 2s, then placed in methanol. For each group, BPA and Bis-GMA release were determined with GC/MS and/or LC/MS at least after one week. Besides, 120 brackets (10 of each type) were bonded over metal teeth, then debonded, and the weight and the surface of resin composite residues were measured. BPA and Bis-GMA release of adhesive residues were extrapolated from the data obtained with the cylinders. Besides, BPA release from a heated Bis-GMA solution was measured. RESULTS: With GC/MC, BPA was detected in all samples. With LC/MS, BPA was detected only from samples immersed in MeOH; Bis-GMA was detected, in varying amount according to the extraction media and the light-curing time. BPA was found after heating of the Bis-GMA solution. SIGNIFICANCE: Contamination risk and the heat applied in GC/MS may overestimate the BPA release from resin composite. Based on the LC/MS results, the risk of BPA release after orthodontic bonding would be more than 42000 times lower than the TDI for a 30-kg child. PMID- 29183673 TI - Effect of tribochemical treatments and silane reactivity on resin bonding to zirconia. AB - OBJECTIVE: The aim of the study was to assess the roughness, structure and bond strength with zirconia of four grit-blasting treatments combined with three silane types, the reactivity of which was evaluated, as well. METHODS: The grit blasted treatments performed on zirconia (Lava) were alumina (ALU), CoJet (COJ), SilJet (SLJ) and SilJet Plus (SJP, with silica-encapsulated silane). The other two silanes selected were the S-Bond (SB, prehydrolyzed) and Clearfil Ceramic Primer Plus (CP, prehydrolyzed with 10-MDP). The activity of the silanols in the silanes was evaluated by FTIR spectroscopy. Optical profilometry and Raman microspectroscopy were used for the assessment of roughness (Sa, Sz, Sdr parameters) and structure (monoclinic volume-Vm) of zirconia, before (REF) and after grit-blasting, and a shear bond strength (SBS) with a flowable resin composite, for the investigation of the bonding capacity of the treatments. RESULTS: Only SB demonstrated reactive silanols. CP and the SJP silanes were mostly in a polymerized siloxane state. Roughness was increased after grit blasting as follows: ALU>SLJ,SJP>COJ>REF (Sa,Sz) and ALU>SLJ,COJ,SJP>REF (Sdr). ALU demonstrated the highest Vm (7.52%) from all other treatments (4.16-4.81%) and the REF (0%). COJ and SLJ showed the highest SBS (14-15.94MPa) regardless of the silane type used. SJP showed no significant differences from SLJ-SB and COJ SB. Weibull analysis showed a reliability (beta) ranking of COJ, SJP, SLJ, ALU CP>ALU-SB>REF and a characteristic life (eta) ranking of COJ, SLJ, >=SLJ-SB, SJP, ALU>=ALU-SB,REF-CP>REF-SB. SIGNIFICANCE: The reactivity of the silanes used showed great variations to support a predictable effect in all treatments. CP with deactivated silanols demonstrated a) the most reliable and strongest treatment with a silica-rich powder (COJ), despite the lowest Sa,Sz substrate values and b) high strength with a low-silica powder (SLJ) with higher Sa,Sz substrate values. Therefore, it may be concluded that 10-MDP greatly contributes to the bonding mechanism of the silane containing primers. PMID- 29183674 TI - Effects of different sterilization methods on surface characteristics and biofilm formation on zirconia in vitro. AB - OBJECTIVE: The current laboratory study was to investigate the effect of different sterilization treatments on surface characteristics of zirconia, and biofilm formation on zirconia surface after exposure to these sterilization treatments. METHODS: Commercially available zirconia discs (Cerconbase, Degu Dent, Hanau, Germany) were prepared and polished to the same value of surface roughness. The discs were treated with one of the following sterilization methods steam autoclave sterilization, dry heat sterilization, ultraviolet C (UVC) irradiation, and gamma (gamma) ray irradiation. The characteristics of zirconia surfaces were evaluated by scanning electron microscopy (SEM), surface roughness, surface free energy (SFE), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD) measurements. Then, Staphylococcus aureus (S.a.) and Porphyromonas gingivalis (P.g.) bacteria were used and cultured on the respective sterilized zirconia surfaces. The amount of biofilm formation on zirconia surface was quantified by colony forming unit (CFU) counts. RESULTS: Significant modifications were detected on the colour and SFE of zirconia. The colour of zirconia samples after UVC irradiation became light yellow whilst dark brown colour was observed after gamma ray irradiation. Moreover, UVC and gamma ray irradiation increased the hydrophilicity of zirconia surface. Overall, dry heat sterilized samples showed the significantly lowest amount of bacteria growth on zirconia, while UVC and gamma ray irradiation resulted in the highest. SIGNIFICANCE: It is evident that various sterilization methods could change the surface which contribute to different biofilm formation and colour on zirconia. PMID- 29183675 TI - Red nucleus interleukin-6 participates in the maintenance of neuropathic pain through JAK/STAT3 and ERK signaling pathways. AB - We previously reported that interleukin-6 (IL-6) in the red nucleus (RN) is up regulated at 3weeks after spared nerve injury (SNI), and plays facilitated role in the later maintenance of neuropathic pain. The current study aimed to reveal the roles of different signaling pathways, including Janus kinase/signal transducer and activator of transcription 3 (JAK/STAT3), extracellular signal regulated kinase (ERK), c-Jun N-terminal kinase (JNK), p38 mitogen-activated protein kinase (MAPK) and phosphatidylinositide 3-kinase/protein kinase B (PI3K/AKT), in RN IL-6-mediated pain modulation. In accord with the increase of IL-6 in the RN following SNI, the protein levels of phospho-STAT3 (p-STAT3), p ERK and p-JNK were also up-regulated in the RN contralateral to the nerve injury side at 3weeks after SNI. The increases of p-STAT3 and p-ERK (but not p-JNK) were associated with IL-6 and could be blocked by anti-IL-6 antibody. Microinjection of JAK2 inhibitor AG490, ERK inhibitor PD98059 and also JNK inhibitor SP600125 into the RN significantly increased the paw withdrawal threshold (PWT) and alleviated SNI-induced mechanical allodynia. Further studies showed that microinjection of recombinant rat IL-6 (rrIL-6, 20ng) into the RN of normal rats significantly decreased the PWT of rats and increased the local protein levels of p-STAT3 and p-ERK, but not p-JNK. Pre-treatment with AG490 and PD98059 could prevent IL-6-induced mechanical allodynia. Whereas, p-p38 MAPK and p-AKT did not show any expression changes in the RN of rats with SNI or rats treated with rrIL 6. These results suggest that RN IL-6 participates in the later maintenance of SNI-induced neuropathic pain and plays facilitated role through activating JAK/STAT3 and ERK signaling pathways.

PMID- 29183676 TI - Depolarization and electrical stimulation enhance in vitro and in vivo sensory axon growth after spinal cord injury. AB - Activity dependent plasticity is a key mechanism for the central nervous system (CNS) to adapt to its environment. Whether neuronal activity also influences axonal regeneration in the injured CNS, and whether electrical stimulation (ES) can activate regenerative programs in the injured CNS remains incompletely understood. Using KCl-induced depolarization, in vivo ES followed by ex-vivo neurite growth assays and ES after spinal cord lesions and cell grafting, we aimed to identify parameters important for ES-enhanced neurite growth and axonal regeneration. Using cultures of sensory neurons, neurite growth was analyzed after KCl-induced depolarization for 1-72h. Increased neurite growth was detected after short-term stimulation and after longer stimulation if a sufficient delay between stimulation and growth measurements was provided. After in vivo ES (20Hz, 2* motor threshold, 0.2ms, 1h) of the intact sciatic nerve in adult Fischer344 rats, sensory neurons showed a 2-fold increase in in vitro neurite length one week later compared to sham animals, an effect not observed one day after ES. Longer ES (7h) and repeated ES (7days, 1h each) also increased growth by 56-67% one week later, but provided no additional benefit. In vivo growth of dorsal column sensory axons into a graft of bone marrow stromal cells 4weeks after a cervical spinal cord lesion was also enhanced with a single post-injury 1h ES of the intact sciatic nerve and was also observed after repeated ES without inducing pain-like behavior. While ES did not result in sensory functional recovery, our data indicate that ES has time-dependent influences on the regenerative capacity of sensory neurons and might further enhance axonal regeneration in combinatorial approaches after SCI. PMID- 29183678 TI - [Description of contributing factors in adverse events related to patient safety and their preventability]. AB - OBJECTIVE: To assess the extent of healthcare related adverse events (AEs), their effect on patients, and their seriousness. To analyse the factors leading to the development of AEs, their relationship with the damage caused, and their degree of preventability. DESIGN: Retrospective descriptive study. LOCATION: Porrino, Pontevedra, Spain, Primary Care Service, from January-2014 to April-2016. PARTICIPANTS AND/OR CONTEXT: Reported AEs were entered into the Patient Safety Reporting and Learning System (SiNASP). METHOD: The variables measured were: Near Incident (NI) an occurrence with no effect or harm on the patient; Adverse Event (AE) an occurrence that affects or harms a patient. The level of harm is classified as minimal, minor, moderate, critical, and catastrophic. Preventability was classified as little evidence of being preventable, 50% preventable, and sound evidence of being preventable. DATA ANALYSIS: percentages and Chi-squared test for qualitative variables; P<.05 with SPSS.15. DATA SOURCE: SiNASP. Ethical considerations: approved by the Research Ethics Committee (2016/344). RESULTS: There were 166 recorded AEs (50.6% in males, and 46.4% in women. The mean age was 60.80years). Almost two-thirds 62.7% of AEs affected the patient, with 45.8% causing minimal damage, while 2.4% caused critical damages. Healthcare professionals were a contributing factor in 71.7% of the AEs, with the trend showing that poor communication and lack of protocols were related to the damage caused. Degree of preventability: 96.4%. CONCLUSIONS: Most AEs affected the patient, and were related to medication, diagnostic tests, and laboratory errors. The level of harm was related to communication problems, lack of, or deficient, protocols and a poor safety culture. PMID- 29183679 TI - Angiographic perfusion imaging of intracranial stenting. AB - Two-dimensional angiographic perfusion imaging (2DAP) is a new technique permitting perfusion imaging during angiography, and has been used to study cerebral vasospasm. Here we report our experience with this technique following angioplasty and stent placement in a patient with symptomatic and medically refractory stenosis of the right supraclinoid internal carotid artery. We found that intraprocedural angiographic perfusion imaging provided real-time and objective evidence of improved cerebral perfusion during intervention. Following treatment, the patient remains symptom-free at last follow-up. PMID- 29183680 TI - Drug therapy for chronic subdural hematoma: Bench to bedside. PMID- 29183681 TI - Effects of repeated nerve injuries at different time intervals on functional recovery and nerve innervation. AB - Effects of repeated nerve injuries on functional recovery and nerve innervation were examined in rodents. Crush injuries of the sciatic nerve were inflicted on adult rats and repeated twice or thrice at different time intervals of 1, 2, 3, and 4 weeks. Motor function was assessed by the static sciatic index at 1, 7, 14, 21, 28, 35, 42, 49, and 56 days after the final crush. The rates of nerve innervation of the tibialis anterior muscle, a main muscle innervated by the common peroneal nerve, were evaluated by the quantification of betaIII-tubulin positive nerve terminals and alpha-bungarotoxin-positive acetylcholine receptors 21 and 56 days after the final crush of triple nerve injuries at 1-, 2-, 3-, and 4-week intervals. Compared with single nerve crush injury, delayed recovery of motor function was observed in repeated crush injuries. In addition, recoveries in the triple crush groups were slower than those in the double crush groups. The rates of reinnervation were lower in the triple crush groups than in the single crush groups, both at 21 days (single: 59.7%; triple: 54.1%-56.1%) and 56 days (single: 88.8%; triple: 72.5%-83.0%) after the final crush, except in the groups with 1-week (triple: 73.8%) and 2-week (triple: 70.5%) intervals at 21 days after the final crush. We concluded that the recovery of motor function was delayed according to the number of repetitions of crush injuries, and that the rates of nerve innervation were still low in the triple crush groups 8 weeks after the final crush. PMID- 29183682 TI - Treatment of a glioblastoma multiforme dural metastasis with stereotactic radiosurgery: A case report and select review of the literature. AB - Glioblastoma multiforme (GBM) is a primary brain neoplasm accounting for approximately 75% of all high grade gliomas. It is diffusely infiltrative and exhibits rapid proliferation with a poor overall prognosis. Maximum surgical resection and postoperative radiotherapy, accompanied by concurrent and adjuvant temozolomide chemotherapy, remain the standard of care without major therapeutic advances over the past 10 years. Herein, we present the case of a 64-year-old Caucasian male with a GBM who subsequently developed a left frontal dural metastasis, subsequently treated with stereotactic radiosurgery (20 Gy in 1 fraction). With six month follow-up, the patient showed near complete resolution of his dural metastases and no overall change in neurological symptoms or side effects following radiosurgery. Due to the paucity of clinical literature regarding dural metastases from GBM, its optimal treatment remains unknown. While the role of SRS has yet to be defined in this setting, here we provide evidence suggesting its overall efficacy in the treatment of select dural GBM metastases. PMID- 29183683 TI - Cellular diversity of the somatosensory cortical map plasticity. AB - Sensory maps are representations of the sensory epithelia in the brain. Despite the intuitive explanatory power behind sensory maps as being neuronal precursors to sensory perception, and sensory cortical plasticity as a neural correlate of perceptual learning, molecular mechanisms that regulate map plasticity are not well understood. Here we perform a meta-analysis of transcriptional and translational changes during altered whisker use to nominate the major molecular correlates of experience-dependent map plasticity in the barrel cortex. We argue that brain plasticity is a systems level response, involving all cell classes, from neuron and glia to non-neuronal cells including endothelia. Using molecular pathway analysis, we further propose a gene regulatory network that could couple activity dependent changes in neurons to adaptive changes in neurovasculature, and finally we show that transcriptional regulations observed in major brain disorders target genes that are modulated by altered sensory experience. Thus, understanding the molecular mechanisms of experience-dependent plasticity of sensory maps might help to unravel the cellular events that shape brain plasticity in health and disease. PMID- 29183684 TI - Age-related changes in the neural networks supporting semantic cognition: A meta analysis of 47 functional neuroimaging studies. AB - Semantic cognition is central to understanding of language and the world and, unlike many cognitive domains, is thought to show little age-related decline. We investigated age-related differences in the neural basis of this critical cognitive domain by performing an activation likelihood estimation (ALE) meta analysis of functional neuroimaging studies comparing young and older people. On average, young people outperformed their older counterparts during semantic tasks. Overall, both age groups activated similar left-lateralised regions. However, older adults displayed less activation than young people in some elements of the typical left-hemisphere semantic network, including inferior prefrontal, posterior temporal and inferior parietal cortex. They also showed greater activation in right frontal and parietal regions, particularly those held to be involved in domain-general controlled processing, and principally when they performed more poorly than the young. Thus, semantic processing in later life is associated with a shift from semantic-specific to domain-general neural resources, consistent with the theory of neural dedifferentiation, and a performance-related reduction in prefrontal lateralisation, which may reflect a response to increased task demands.

PMID- 29183687 TI - Functional role for cortical-striatal circuitry in modulating alcohol self administration. AB - The cortical-striatal brain circuitry is heavily implicated in drug-use. As such, the present study investigated the functional role of cortical-striatal circuitry in modulating alcohol self-administration. Given that a functional role for the nucleus accumbens core (AcbC) in modulating alcohol-reinforced responding has been established, we sought to test the role of cortical brain regions with afferent projections to the AcbC: the medial prefrontal cortex (mPFC) and the insular cortex (IC). Long-Evans rats were trained to self-administer alcohol (15% alcohol (v/v)+2% sucrose (w/v)) during 30 min sessions. To test the functional role of the mPFC or IC, we utilized a chemogenetic technique (hM4Di-Designer Receptors Activation by Designer Drugs) to silence neuronal activity prior to an alcohol self-administration session. Additionally, we chemogenetically silenced mPFC->AcbC or IC->AcbC projections, to investigate the role of cortical-striatal circuitry in modulating alcohol self-administration. Chemogenetically silencing the mPFC decreased alcohol self-administration, while silencing the IC increased alcohol self-administration, an effect absent in mCherry-Controls. Interestingly, silencing mPFC->AcbC projections had no effect on alcohol self-administration. In contrast, silencing IC->AcbC projections decreased alcohol self-administration, in a reinforcer-specific manner as there was no effect in rats trained to self administer sucrose (0.8%, w/v). Additionally, no change in self-administration was observed in the mCherry-Controls. Together these data demonstrate the complex role of the cortical-striatal circuitry while implicating a role for the insula striatal circuit in modulating ongoing alcohol self-administration. PMID- 29183686 TI - Neurocognitive dysfunction following repeated binge-like self-administration of the synthetic cathinone 3,4-methylenedioxypyrovalerone (MDPV). AB - Synthetic cathinones, frequently referred to as "bath salts", have significant abuse potential, and recent evidence suggests that these novel psychoactive substances can also produce cognitive deficits as well as cytotoxic effects. However, most of these latter findings have been obtained either using high concentrations in vitro or following non-contingent high dose administration in vivo. The present study utilized a model of long-term voluntary binge-like self administration to determine potential detrimental effects of synthetic cathinones on cognitive function and their known underlying neural circuits, collectively referred to as neurocognitive dysfunction. Male Sprague-Dawley rats were allowed to self-administer the cocaine-like synthetic cathinone 3,4 methylenedioxypyrovalerone (MDPV, 0.03 mg/kg/infusion i.v.) in 96-hr sessions, or saline as a control. A total of five 96-hr sessions were conducted, each separated by 3 days of abstinence in the home cage. Three weeks following the last 96-hr session, animals underwent assessment of cognitive function using spatial object recognition (SOR) and novel object recognition (NOR) tasks, after which brains were harvested and assessed for neurodegeneration using FluoroJade C (FJC). Compared to animals self-administering saline, animals self-administering MDPV demonstrated (1) robust drug intake that escalated over time, (2) deficits in NOR but not SOR, and (3) neurodegeneration in the perirhinal and entorhinal cortices. These results indicate that repeated binge-like intake of MDPV can induce neurocognitive dysfunction. In addition, utilization of rodent models of extended binge-like intake may provide insight into potential mechanisms and/or approaches to prevent or reverse the detrimental effects of abused substances on cognitive and neurobiological functioning.

PMID- 29183688 TI - An exploratory investigation of brain-selective estrogen treatment in males using a mouse model of Alzheimer's disease. AB - Estrogens are neuroprotective, and studies suggest that they may mitigate the pathology and symptoms of Alzheimer's disease (AD) in female models. However, central estrogen effects have not been examined in males in the context of AD. The purpose of this follow-up study was to assess the benefits of a brain selective 17beta-estradiol estrogen prodrug, 10beta,17beta-hydroxyestra-1,4-dien 3-one (DHED), also in the male APPswe/PS1dE9 double-transgenic mouse model of the disease. After continuously exposing 6-month old animals to DHED for two months, their brains showed decreased amyloid precursor and amyloid-beta protein levels. The DHED-treated APPswe/PS1dE9 double transgenic subjects also exhibited enhanced performance in a cognitive task, while 17beta-estradiol treatment did not reach statistical significance. Taken together, data presented here suggest that DHED may also have therapeutic benefit in males and warrant further investigations to fully elucidate the potential of targeted estrogen therapy for a gender independent treatment of early-stage AD.

AB - OBJECTIVE: To follow up pain in the immediate postoperative period, using an elastomeric pump in anterior cruciate ligament surgery. MATERIAL AND METHODS: 309 patients who had undergone anterior cruciate ligament repair with bone-tendon bone allograft. Pain control was assessed with a visual analogue scale (VAS) during the immediate postoperative period, in the postoperative care unit, in the recovery room, and after the first 24-48-72hours following home discharge. The need for rescue medication, adverse effects observed and emergency visits were also registered. RESULTS: 309 patients were assessed (264 males, 45 females), mean age 33 (range: 18 - 55). Postoperative pain was mild in 44.7% of patients, and 38.5% were pain-free. At discharge, 41.1% of patients reported mild pain and 57% were pain-free. At home, mild to moderate levels of pain were maintained and over 97% of patients presented VAS values <= 3. Fewer than 3% had adverse effects, 8.7% had to use analgesic medication at some point. Pruritus occurred in less than 1% of patients receiving intravenous analgesia at home, and fewer than 2% had device-related complications. DISCUSSION: There is no consensus regarding the postoperative management of anterior cruciate ligament lesions, although most surgeons use multimode anaesthesia and different combinations of analgesics to reduce postoperative pain. CONCLUSIONS: The use of an intravenous elastomeric pump as postoperative analgesia for anterior cruciate ligamentoplasty has yielded good results.

AB - cFos expression in the preoptic area (PO), which is thermoregulatory center increased by both heat and cold exposures; however, the regional difference is unknown yet. We aimed to determine if cFos expression in the PO was regionally different between heat and cold exposures. Mice were exposed to 27, 10, or 38 degrees C for 90min, and body temperature (Tb) was measured. cFos-immunoreactive (cFos-IR) cells in the PO were counted by separating the PO into the ventral and dorsal parts in the rostral (bregma 0.38mm), central (-0.10mm), and caudal ( 0.46mm) planes. Tb at 10 degrees C remained unchanged; however, it increased at 38 degrees C. Counts of cFos-IR cells in all areas were greater at 38 degrees C than at 27 degrees C. In the dorsal and ventral parts of the central and the dorsal part of caudal PO, counts of cFos-IR cells were greater at 10 degrees C than at 27 degrees C. In conclusion, the areas of increased cFos expression in the PO in the heat were different that in the cold in mice.

AB - Glutathione provides protection from oxidative stress-induced damage through the reduction of reactive oxygen species for the maintenance of oxidant homeostasis. Our purpose was to test the effects of depleting tissue GSH by buthionine sulfoximine on brain oxidative metabolism and cognitive performance in rats. Glutathione depletion induced a compensatory response on antioxidant enzymes and increase of cell damage indicators in all the examined cerebral areas at 24h. The effect of GSH depletion on spatial memory recorded at 24h post-surgery showed significant differences between experimental groups for the escape latency to the platform and percentage of total swim distance spending in the target quadrant. The acquisition of a new spatial condition 24h after GSH depletion revealed differences between experimental groups for latencies, swim distance, swim distance in the target quadrant and percentage of total swim distance spending in the target quadrant. The ability of BSO treated group to maintain a restraining behavior was significantly smaller compared with control group. We founded significant correlation among variables of the behavioral studies and oxidative stress indicators. In conclusion, our model shows how increased ROS production by transitory glutathione depletion constitutes the primary cause to neuronal metabolic stress with alterations in synaptic signaling and cognitive deficits. PMID- 29183694 TI - Isolation of 2-deoxy-scyllo-inosose (DOI)-assimilating yeasts and cloning and characterization of the DOI reductase gene of Cryptococcus podzolicus ND1. AB - 2-Deoxy-scyllo-inosose (DOI) is the first intermediate in the 2-deoxystreptamine containing aminoglycoside antibiotic biosynthesis pathway and has a six-membered carbocycle structure. DOI is a valuable material because it is easily converted to aromatic compounds and carbasugar derivatives. In this study, we isolated yeast strains capable of assimilating DOI as a carbon source. One of the strains, Cryptococcus podzolicus ND1, mainly converted DOI to scyllo-quercitol and (-) vibo-quercitol, which is a valuable compound used as an antihypoglycemia agent and as a heat storage material. An NADH-dependent DOI reductase coding gene, DOIR, from C. podzolicus ND1 was cloned and successfully overexpressed in Escherichia coli. The purified protein catalyzed the irreversible reduction of DOI with NADH and converted DOI into (-)-vibo-quercitol. The enzyme had an optimal pH of 8.5 and optimal temperature of 35 degrees C, respectively. The kcat of this enzyme was 9.98 s-1, and the Km values for DOI and NADH were 4.38 and 0.24 mM, respectively. The enzyme showed a strong preference for NADH and showed no activity with NADPH. Multiple-alignment analysis of DOI reductase revealed that it belongs to the GFO_IDH_MocA protein family and is an inositol dehydrogenase homolog in other fungi, such as Cryptococcus gattii, and bacteria, such as Bacillus subtilis. This is the first identification of a DOI-assimilating yeast and a gene involved in DOI metabolism in fungi. PMID- 29183695 TI - Discrimination of wine from grape cultivated in Japan, imported wine, and others by multi-elemental analysis. AB - Differences in mineral concentrations were examined among three types of wine in the Japanese market place: Japan wine, imported wine, and domestically produced wine mainly from foreign ingredients (DWF), where Japan wine has been recently defined by the National Tax Agency as domestically produced wine from grapes cultivated in Japan. The main objective of this study was to examine the possibility of controlling the authenticity of Japan wine. The concentrations of 18 minerals (Li, B, Na, Mg, Si, P, S, K, Ca, Mn, Co, Ni, Ga, Rb, Sr, Mo, Ba, and Pb) in 214 wine samples were determined by inductively coupled-plasma mass spectrometry (ICP-MS) and ICP-atomic emission spectrometry (ICP-AES). In general, Japan wine had a higher concentration of potassium and lower concentrations of eight elements (Li, B, Na, Si, S, Co, Sr, and Pb) as compared with the other two groups of wine. Linear discriminant analysis (LDA) models based on concentrations of the 18 minerals facilitated the identification of three wine groups: Japan wine, imported wine, and DWF with a 91.1% classification score and 87.9% prediction score. In addition, an LDA model for discrimination of wine from four domestic geographic origins (Yamanashi, Nagano, Hokkaido, and Yamagata Prefectures) using 18 elements gave a classification score of 93.1% and a prediction score of 76.4%. In summary, we have shown that an LDA model based on mineral concentrations is useful for distinguishing Japan wine from other wine groups, and can contribute to classification of the four main domestic wine producing regions of Japan. PMID- 29183696 TI - Isolation of 5-hydroxymethylfurfural biotransforming bacteria to produce 2,5 furan dicarboxylic acid in algal acid hydrolysate. AB - In dealing with lignocellulosic and algal biomass, thermal acid hydrolysis is an economical and efficient method. In this process, 5-hydroxy-methylfurfural (5 HMF) is formed unavoidably, which inhibits downstream reducing sugar fermentation. Fortunately, 5-HMF can be biotransformed into 2,5-furan dicarboxylic acid (FDCA), the top 14 biomass platform molecules. Base on the connection between 5-HMF removal and FDCA production, microbes capable of biotransforming 5-HMF into FDCA are beneficial to raise biofuel yield and potential molecule production. In this research, pure strain Methylobacterium radiotolerans G-2 capable of transforming 5-HMF into FDCA was enriched and isolated from local campus soil, and its abilities of 5-HMF biotransformation and FDCA production were characterized. Strain M. radiotolerans G-2 could completely transform 1000 mg/L 5-HMF into FDCA with maximum concentration of 513.9 mg/L at an initial pH of 7 at 26 degrees C. Algal acid hydrolysate after two-fold dilution was suitable for strain M. radiotolerans G-2 to perform 5-HMF biotransformation, and 459.7 mg/L FDCA could be obtained. Interestingly, strain M. radiotolerans G-2 did not significantly consume reducing sugar and reducing sugar consuming efficiency was less than 16%. PMID- 29183697 TI - The potential impact on the biodegradation of organic pollutants from composting technology for soil remediation. AB - Large numbers of organic pollutants (OPs), such as polycyclic aromatic hydrocarbons, pesticides and petroleum, are discharged into soil, posing a huge threat to natural environment. Traditional chemical and physical remediation technologies are either incompetent or expensive, and may cause secondary pollution. The technology of soil composting or use of compost as soil amendment can utilize quantities of active microbes to degrade OPs with the help of available nutrients in the compost matrix. It is highly cost-effective for soil remediation. On the one hand, compost incorporated into contaminated soil is capable of increasing the organic matter content, which improves the soil environment and stimulates the metabolically activity of microbial community. On the other hand, the organic matter in composts would increase the adsorption of OPs and affect their bioavailability, leading to decreased fraction available for microorganism-mediated degradation. Some advanced instrumental analytical approaches developed in recent years may be adopted to expound this process. Therefore, the study on bioavailability of OPs in soil is extremely important for the application of composting technology. This work will discuss the changes of physical and chemical properties of contaminated soils and the bioavailability of OPs by the adsorption of composting matrix. The characteristics of OPs, types and compositions of compost amendments, soil/compost ratio and compost distribution influence the bioavailability of OPs. In addition, the impact of composting factors (composting temperature, co-substrates and exogenous microorganisms) on the removal and bioavailability of OPs is also studied. PMID- 29183698 TI - Titanium and polyether ether ketone (PEEK) patient-specific sub-periosteal implants: two novel approaches for rehabilitation of the severely atrophic anterior maxillary ridge. AB - The aim of this study was to assess two new protocols for single-stage rehabilitation of the severely atrophic maxillary ridge using customized porous titanium or polyether ether ketone (PEEK) sub-periosteal implants. Ten patients with a severely atrophic anterior maxillary alveolar ridge were divided randomly into two groups (five patients in each) to receive customized sub-periosteal implants fabricated via CAD/CAM technology: group 1, porous titanium implants; group 2, PEEK implants. Prosthetic loading with fixed acrylic bridges was performed 1 month postoperative. The implants were followed-up for 12 months and evaluated for the presence of any sign of radiographic bone resorption, mobility, infection, prosthetic fracture, or implant exposure. The immediate postoperative period was uneventful except for one case complicated by wound dehiscence in group 1. At 12 months, all implants were functionally stable and the patients were comfortable with the prostheses. No signs of radiographic bone resorption, mobility, infection, or prosthetic fracture were observed. Within the limitations of this study, the application of customized porous titanium and PEEK sub periosteal implants produced through CAD/CAM technology appears to be an acceptable method for single-stage prosthetic rehabilitation of the severely atrophic edentulous anterior maxilla. This study was awarded the best case study at the academy of osseintegration annual meeting 2017, Orlando, Florida. PMID- 29183699 TI - Three-dimensional changes to the upper airway after maxillomandibular advancement with counterclockwise rotation: a systematic review and meta-analysis. AB - The aim of this study was to evaluate the effect of counterclockwise (CCW) rotation and maxillomandibular advancement (MMA) on the upper airway space using three-dimensional images. An electronic search was performed in the PubMed, Cochrane Library, Scopus, Virtual Health Library, Web of Science, and OpenGrey databases (end date July 2016); a hand-search of primary study reference lists was also conducted. The inclusion criteria encompassed computed tomography evaluations of the upper airway spaces of adult patients undergoing orthognathic surgery with CCW rotation and MMA. The articles were evaluated for risk of bias with a tool for before-and-after studies. A meta-analysis was performed with the mean differences using a random-effects model. Heterogeneity was assessed with the Q-test and the I2 index. The meta-analysis revealed significant (P<0.001) increases in both the total airway volume (effect size of 6832mm3 and confidence interval of 5554-8109mm3) and the minimum axial area (effect size of 92mm2 and confidence interval of 70-113mm2). The heterogeneity was low in both comparisons (I2=38% and 7%, respectively). The technique of mandibular advancement with CCW rotation produced significant increases in the volumes and areas of the upper airway spaces. PMID- 29183700 TI - Attachment and eating: A meta-analytic review of the relevance of attachment for unhealthy and healthy eating behaviors in the general population. AB - Attachment relationships play an important role in people's wellbeing and affliction with physical and mental illnesses, including eating disorders. Seven reviews from the clinical field have consistently shown that higher attachment insecurity-failure to form trusting and reliable relationships with others systematically characterized individuals with eating disorders. Nevertheless, to date, it is unclear whether (and if so how) these findings apply to the population at large. Consequently, the objective of the present meta-analysis is to quantify the relationship between attachment and unhealthy and healthy eating in the general population. Data from 70 studies and 19,470 participants were converted into r effect sizes and analysed. Results showed that higher attachment insecurity (r = 0.266), anxiety (r = 0.271), avoidance (r = 0.119), and fearfulness (r = 0.184) was significantly associated with more unhealthy eating behaviors, ps = 0.000; conversely, higher attachment security correlated with lower unhealthy eating behaviors (r = -0.184, p = 0.000). This relationship did not vary across type of unhealthy eating behavior (i.e., binge eating, bulimic symptoms, dieting, emotional eating, and unhealthy food consumption). The little exploratory evidence concerning healthy eating and attachment was inconclusive with one exception-healthy eating was associated with lower attachment avoidance (r = -0.211, p = 0.000). Our results extend previous meta-analytic findings to show that lack of trusting and reliable relationships does not only set apart eating disordered individuals from controls, but also characterizes unhealthy eating behaviors in the general population. More evidence is needed to determine how attachment and healthy eating are linked and assess potential mechanisms influencing the attachment-eating relationship. PMID- 29183702 TI - Minimally invasive hepatectomy conversions: an analysis of risk factors and outcomes. AB - BACKGROUND: Surgical approach may influence morbidity following hepatectomy. This study sought to compare outcomes in minimally invasive surgery (MIS), conversion from MIS to open, and planned open hepatectomy patients and analyze factors leading to conversion. METHODS: The 2014 National Surgical Quality Improvement Program dataset was queried for patients undergoing hepatectomy. Patients were divided into three cohorts: MIS, open, or conversion. Propensity matching was performed to compare MIS vs. conversion (3:1) and open vs. conversion (8:1). The logistic regression model was used to identify odds ratios for conversion. RESULTS: Patients undergoing conversion had a higher transfusion rate (26% vs. 9%, p < 0.001), longer length of stay (5 vs. 3 days, p < 0.001), and higher morbidity (38% vs. 18%, p < 0.001) than MIS patients. Patients who underwent conversion had similar short-term outcomes to those who had planned open procedures. Independent predictors of conversion included hypertension (OR 1.91; 95% CI 1.12-3.26) and right lobectomy (OR 20.23; 95% CI 3.74-109.35). CONCLUSION: Patients with hypertension and those undergoing right lobectomy had a higher risk of conversion to open procedure. Conversion resulted in higher morbidity and longer length of stay compared to MIS patients, but outcomes were similar to planned open procedures. PMID- 29183701 TI - Effect of snack-food proximity on intake in general population samples with higher and lower cognitive resource. AB - OBJECTIVE: Placing snack-food further away from people consistently decreases its consumption ("proximity effect"). However, given diet-related health inequalities, it is important to know whether interventions that alter food proximity have potential to change behaviour regardless of cognitive resource (capacity for self-control). This is often lower in those in lower socio-economic positions, who also tend to have less healthy diet-related behaviours. Study 1 aims to replicate the proximity effect in a general population sample and estimate whether trait-level cognitive resource moderates the effect. In a stronger test, Study 2 investigates whether the effect is similar regardless of manipulated state-level cognitive resource. METHOD: Participants were recruited into two laboratory studies (Study 1: n = 159; Study 2: n = 246). A bowl of an unhealthy snack was positioned near (20 cm) or far (70 cm) from the participant, as randomised. In Study 2, participants were further randomised to a cognitive load intervention. The pre-specified primary outcome was the proportion of participants taking any of the snack. RESULTS: Significantly fewer participants took the snack when far compared with near in Study 2 (57.7% vs 70.7%, beta = 1.63, p = 0.020), but not in Study 1 (53.8% vs 63.3%, X2 = 1.12, p = 0.289). Removing participants who moved the bowl (i.e. who did not adhere to protocol), increased the effect-sizes: Study 1: 39.3% vs 63.9%, X2 = 6.43, p = 0.011; Study 2: 56.0% vs 73.9%, beta = -2.46, p = 0.003. Effects were not moderated by cognitive resource. CONCLUSIONS: These studies provide the most robust evidence to date that placing food further away reduces likelihood of consumption in general population samples, an effect unlikely to be moderated by cognitive resource. This indicates potential for interventions altering food proximity to contribute to addressing health inequalities, but requires testing in real-world settings.

PMID- 29183703 TI - A comparison of outcomes between open, laparoscopic and robotic pancreaticoduodenectomy. AB - BACKGROUND: The advantages and comparison of minimally invasive techniques for pancreaticoduodenectomies have not been fully explored using large national multicenter data. STUDY DESIGN: A retrospective review of NSQIP targeted data from 2014 to 2015 was performed. Demographics and outcomes were compared between open (OPD), laparoscopic (LPD) and robotic pancreaticoduodenectomies (RPD). RESULTS: Of 6827 pancreaticoduodenectomies, 6336 (92.8%) were OPD, 280 (4.1%) were LPD, and 211 (3.1%) were RPD. Compared to OPD, LPD required more post operative drainage procedures (18.4% vs 13.2%, p = 0.013), had less SSI (3.2% vs 9%, p = 0.001), and had fewer discharges to a new facility (8.1% vs 13%, p = 0.018). Compared to OPD, RPD had less perioperative transfusions (14.2% vs 20.5%, p = 0.026) and more readmissions (23.2% vs 16.7%, p = 0.013). After controlling for differences, LPD was independently associated with decreased 30-day morbidity compared to OPD (OR 0.75, 95% CI 0.56-0.99). There was no difference in 30-day mortality. CONCLUSIONS: This is the first study to compare the outcomes of laparoscopic and robotic pancreaticoduodenectomies to open using the NSQIP database. After controlling for differences between groups, LPD is independently associated with less morbidity. In experienced hands, it appears safe and valuable to pursue refinement of minimally invasive techniques for pancreaticoduodenectomies.

Close similarities exist between these two countries when facing the difficulties to establish a universal reperfusion program for ST elevation myocardial infarction (STEMI). This paper describes the situation of STEMI treatment in both countries, and examines the lessons that Mexico's health care system could adopt from the recent advances accomplished by the STEMI initiative in India.

AB - Dopamine is widely involved in behaviors related to motor activity, cognition, motivation, and reward. Dopamine signal is transduced through the dopamine receptor gene family. The dopamine D1 receptor (D1R) is highly expressed in the striatum, and is responsible for regulating the motor function. Recently, we have reported that the knockdown (KD) mice in which D1R was conditionally eliminated at adult stage, displayed a hypoactivity in the home cage than wild type mice; however, conventional D1R knockout (KO) mice show hyperactive phenotypes. In order to assess whether the difference in the time of eliminating D1R expression affects the behavioral phenotypes, we generated D1R KD mice at the postnatal and adult stages, and compared their motor function with D1R KO mice. Consequently, D1R KD at postnatal and adult stages resulted in severe locomotive defects compared with D1R KO mice. These results suggested that D1R has versatile functions, and the knockdown timing greatly influences the normal motor activity in the adolescent to adult stages.

AB - Studies of lipid reactive CD1d-restricted T cells have focussed on alpha galactosylceramide reactive semi-invariant Type I NKT cells, which influence a broad range of immune responses. Much less is known about other CD1d-restricted T cells with respect to TCR diversity, function, the types of antigens they recognize and how they specifically recognize antigens presented by CD1d. In this review, we reflect on recent literature that highlights unexpected complexity within the pool of CD1d-restricted T cells and emphasize how TCR diversity greatly broadens the scope of antigen recognition. PMID- 29183707 TI - Visual outcomes and management after corneal refractive surgery: A review. AB - Corneal refractive surgery procedures are widely performed to permanently correct refractive errors. Overall, refractive surgeries are safe, predictable and present high rates of satisfaction. Nevertheless, the induced epithelial, stromal and nerve damage alters corneal integrity and function, triggering a regenerative response. Complications that arise from corneal wound healing process might directly impact on visual outcomes of keratorefractive procedures. Most of these complications can be prevented or effectively treated with minimal consequences and minor impact on optical quality. Nevertheless, it is crucial to accurately and timely identify these corneal regeneration-related complications for successful counseling and management. Optometrists, as primary eye care providers, play an essential role in detecting anatomic and functional alterations in vision. It is therefore of great interest for optometrists to be familiar with the principal postoperative complications derived from alterations in regenerative process after corneal laser refractive surgeries. This review aims to provide a basis for optometrists to better understand, identify and manage the main wound healing-related complications after refractive surgery.

PMID- 29183708 TI - Posttranscriptional regulation of lipid metabolism by non-coding RNAs and RNA binding proteins. AB - Alterations in lipoprotein metabolism enhance the risk of cardiometabolic disorders including type-2 diabetes and atherosclerosis, the leading cause of death in Western societies. While the transcriptional regulation of lipid metabolism has been well characterized, recent studies have uncovered the importance of microRNAs (miRNAs), long-non-coding RNAs (lncRNAs) and RNA binding proteins (RBP) in regulating the expression of lipid-related genes at the posttranscriptional level. Work from several groups has identified a number of miRNAs, including miR-33, miR-122 and miR-148a, that play a prominent role in controlling cholesterol homeostasis and lipoprotein metabolism. Importantly, dysregulation of miRNA expression has been associated with dyslipidemia, suggesting that manipulating the expression of these miRNAs could be a useful therapeutic approach to ameliorate cardiovascular disease (CVD). The role of lncRNAs in regulating lipid metabolism has recently emerged and several groups have demonstrated their regulation of lipoprotein metabolism. However, given the high abundance of lncRNAs and the poor-genetic conservation between species, much work will be needed to elucidate the specific role of lncRNAs in controlling lipoprotein metabolism. In this review article, we summarize recent findings in the field and highlight the specific contribution of lncRNAs and RBPs in regulating lipid metabolism.

PMID- 29183712 TI - Correlation between the sudden jump-like increases of the atrio-Hisian interval induced during burst atrial pacing and during programmed atrial stimulation in patients with atrioventricular nodal reentrant tachycardia. AB - PURPOSE: To study the correlation between the sudden prolongations of the atrio Hisian (AH) interval with >=50 ms during burst and programmed atrial stimulation, and to define whether the AH jump during burst atrial pacing is a reliable diagnostic criterion for dual AV nodal physiology. METHODS: Retrospective data on 304 patients with preliminary ECG diagnosis of AV nodal reentrant tachycardia (AVNRT), confirmed during electrophysiological study, was analyzed for the presence of AH jump during burst and programmed atrial stimulation, and for correlation between the pacing modes for inducing the jump. Wilcoxon signed-ranks test and Spearman's bivariate correlation coefficient were applied, significant was P-value <0.05. RESULTS: The population was aged 48.5 +/- 15.7 (12-85) years; males were 38.5%. AH jump occurred during burst atrial pacing in 81% of the patients, and during programmed stimulation - in 78%, P = 0.366. In 63.2% AH jump was induced by both pacing modes; in 17.8% - only by burst pacing; in 14.8% - only by programmed pacing; in 4.2% there was no inducible jump. There was negative correlation between both pacing modes, rho = -0.204, R<0.001. CONCLUSION: Burst and programmed atrial stimulation separately prove the presence of dual AV nodal physiology in 81 and 78% of the patients with AVNRT, respectively. There is negative correlation between the two pacing modes, allowing the combination of the two methods to prove diagnostic in 95.8% of the patients.

AB - Usually an electrocardiogram after right ventricular (RV) pacing should yield left bundle branch block (LBBB) pattern. However, the presence of right bundle branch block (RBBB) pattern after pacemaker implantation should alert the physician to a malposition of lead. We report a case of 18-year-old female who underwent dual chamber pacemaker implantation and had RBBB pattern post implantation. Detailed evaluation revealed an uncomplicated right ventricular outflow tract pacing. The possible causes of this abnormal pattern after an uncomplicated RV pacing are also reviewed.

AB - Sjogren-Larsson syndrome (SLS) is a rare autosomal recessive disorder characterized by ichthyosis, spasticity and intellectual disability. The disease is caused by mutations in the ALDH3A2 gene that encodes fatty aldehyde dehydrogenase. We describe 7 Iranian SLS patients from 5 unrelated consanguineous families. Sequencing of ALDH3A2 identified 4 novel mutations, including a 26-bp deletion (c.25_50del), small in-frame deletion (c.370_372del; p.G124del), a termination (p.Q35Ter) and a missense mutation (p.Lys211Glu). Bacterial expression of the p.Lys211Glu and p.G124del mutations showed little or no detectable enzyme activity. Three of the patients exhibited an unusual neuro regressive clinical course associated with seizures, which may reflect the presence of unidentified genetic or environmental modifiers in this consanguineous population. This cohort represents the largest group of Iranian patients with molecularly confirmed SLS and expands the mutational and clinical spectrum of this disease. PMID- 29183716 TI - The Effect of Total Size of Lesions in Multifocal/Multicentric Breast Cancer on Survival. AB - BACKGROUND: In this study, we aimed to assess the prognostic performance of determining the T stage according to the total size of lesions compared with the size of the largest lesion in the breast in patients with multifocal/multicentric (MF/MC) breast cancer. PATIENTS AND METHODS: The charts of the patients with MF/MC breast cancer who were diagnosed between 2003 and 2014 were reviewed. The T stage of MF/MC tumors was determined according to the largest lesion size (Tmax) as well as the sum of the longest diameters of the lesions (Tsum) in the breast. RESULTS: Multifocal/multicentric tumors were identified in 323 of 3890 patients (8.3%) with breast cancer. Ten-year rates of overall survival (OS; 75% and 74%; P = .965) and disease-free survival (DFS; 66% and 61%; P = .817) were similar in patients with unifocal and MF/MC tumors, respectively. When the T stage was determined by summing the sizes of the lesions, the T stage of 67 (20.7%) and 63 (19.5%) patients advanced from T1 to T2 and from T2 to T3, respectively. Thus, the T stage increased in 130 patients (40.2%) according to American Joint Committee on Cancer. Discriminatory ability of Tsum was better than Tmax in terms of OS and DFS, as shown with higher Royston D and Harrel C statistics and Schemper V values. CONCLUSION: The new T classification proposed in this report stands out as a better predictive classification particularly in patients with low disease burden. PMID- 29183718 TI - Identification and characterization of PP2C phosphatase SjPtc1 in Schistosoma japonicum. AB - Protein phosphorylation, regulated by protein kinases and protein phosphatases, is crucial for protein structure and function in eukaryotic organisms. Type 2C protein phosphatase (PP2C) belongs to the serine/threonine phosphatase family and its activities require the presence of a divalent magnesium or manganese ion. In the present study, a potential PP2C phosphatase (SjPtc1) was identified in Schistosoma japonicum. The SjPTC1 gene was found to be highly expressed in adult worms. A recombinant SjPtc1 protein showed typical PP2C phosphatase activity. Heterologous SjPTC1 expression reversed the sensitivity of yeast ptc1 null mutants toward H2O2, ZnCl2, cisplatin, and rapamycin. Collectively, the results suggest that SjPtc1 may take part in the regulation of cellular responses to oxidative stress, DNA damage stress, and the TOR (target of rapamycin) signaling pathway. PMID- 29183717 TI - Using Wolbachia for Dengue Control: Insights from Modelling. AB - Dengue is the most common arboviral infection of humans, responsible for a substantial disease burden across the tropics. Traditional insecticide-based vector-control programmes have limited effectiveness, and the one licensed vaccine has a complex and imperfect efficacy profile. Strains of the bacterium Wolbachia, deliberately introduced into Aedes aegyptimosquitoes, have been shown to be able to spread to high frequencies in mosquito populations in release trials, and mosquitoes infected with these strains show markedly reduced vector competence. Thus, Wolbachia represents an exciting potential new form of biocontrol for arboviral diseases, including dengue. Here, we review how mathematical models give insight into the dynamics of the spread of Wolbachia, the potential impact of Wolbachia on dengue transmission, and we discuss the remaining challenges in evaluation and development.

Disruption of the gut microbial community due to diet, lifestyle, or antibiotic exposure increases susceptibility to chronic infection and disease. Fecal microbiota transplantation (FMT) involves the transfer of gut microbiota from a healthy donor to a patient in order to restore normal diversity and function of the microbial community. This method has become a well established alternative therapy for the treatment of recurrent Clostridium difficile infection. Recent clinical trials and studies in animal models suggest promise for this method to treat inflammatory bowel diseases, as well as metabolic syndrome. In addition, due to signaling interactions between the gut microbiota and brain, FMT has been suggested as a potential treatment for some psychological disorders, including autism spectrum disorder. Importantly, advances in next-generation sequencing and multi-omics approaches are increasingly improving our understanding of the mechanisms by which FMT results in cure of these various conditions. In this review, we summarize the current applications of FMT and highlight potential future uses and current challenges in understanding and optimizing FMT procedures. PMID- 29183721 TI - Role of Chromatin assembly factor 1 in DNA replication of Plasmodium falciparum. AB - Nucleosome assembly in P. falciparum could be the key process in maintaining its genomic integrity as DNA replicates more than once per cell cycle during several stages of its life cycle. Here, we report the functional characterization of P. falciparum chromatin assembly factor 1 (CAF1), which interacts with several proteins namely PfCAF2, Histones, PfHP1 and others. Consistent with the above findings, we demonstrate the presence of PfCAF1 at the telomeric repeat regions, central and subtelomeric var genes of multiple var gene family along with PfHP1. Further, we report the upregulation of PfCAF1 after treatment with genotoxic agents like MMS and HU. Together, these findings establish role of PfCAF1 in heterochromatin maintenance and as histone chaperone in nucleosome assembly and DNA damage repair. PMID- 29183719 TI - The diverse functions of the hepatitis B core/capsid protein (HBc) in the viral life cycle: Implications for the development of HBc-targeting antivirals. AB - Virally encoded proteins have evolved to perform multiple functions, and the core protein (HBc) of the hepatitis B virus (HBV) is a perfect example. While HBc is the structural component of the viral nucleocapsid, additional novel functions for the nucleus-localized HBc have recently been described. These results extend for HBc, beyond its structural role, a regulatory function in the viral life cycle and potentially a role in pathogenesis. In this article, we review the diverse roles of HBc in HBV replication and pathogenesis, emphasizing how the unique structure of this protein is key to its various functions. We focus in particular on recent advances in understanding the significance of HBc phosphorylations, its interaction with host proteins and the role of HBc in regulating the transcription of host genes. We also briefly allude to the emerging niche for new direct-acting antivirals targeting HBc, known as Core (protein) Allosteric Modulators (CAMs). PMID- 29183722 TI - Kinetic regime of aggregation of UV-irradiated glyceraldehyde-3-phosphate dehydrogenase from rabbit skeletal muscle. AB - The study of the kinetics of aggregation of UV-irradiated proteins has attracted considerable interest, since test systems based on aggregation of proteins denatured by UV radiation can be used for screening of the natural and artificial agents possessing chaperone-like activity (anti-aggregation activity). To provide the proper interpretation of the effects caused by the agents under study, the kinetic mechanism of the aggregation process should be established. In the present work the kinetic data on aggregation of UV-irradiated glyceraldehyde-3 phosphate dehydrogenase (GAPDH) from rabbit skeletal muscle at 37 degrees C (O.I. Maloletkina et al. Biophys. Chem. 163-164 (2012) 11-20) have been analyzed. It has been shown that the stage of aggregate growth follows the first-order kinetics and the experimentally measured rate constant of the first order corresponds to heat-induced structural reorganization of UV-irradiated GAPDH containing concealed damage. PMID- 29183723 TI - SREBP1-driven lipid desaturation supports clear cell renal cell carcinoma growth through regulation of NF-kappaB signaling. AB - Clear cell renal cell carcinoma (ccRCC), the most common type of kidney cancers, is an incurable and lethal disease. Although great progresses have been made in understanding the mechanism of ccRCC, metabolic reprogramming in ccRCC remains largely unclear. Here, we showed that lipid desatutation might be a metabolic hallmark of ccRCC. We demonstrated sterol regulatory element-binding protein 1 (SREBP1) is overexpressed in ccRCC cell lines and positively correlated with NF kappaB activation. Further, SREBP1 is required for lipid desaturation and cell growth in ccRCC. Mechanistically, we demonstrated that SREBP1-driven lipid desaturation promotes NF-kappaB activation. Our finding reveals a crucial roles for SREBP1 in lipid desaturation of ccRCC through regulation of NF-kappaB signaling, which provides not only new insights in regulatory mode of NF-kappaB signaling but also a novel target for potential metabolic therapies. PMID- 29183724 TI - CD40L and TNF both activate the classical NF-kappaB pathway, which is not required for the CD40L induced alternative pathway in endothelial cells. AB - CD40L and TNF signal through engagement of their respective receptors, which are both members of the TNF receptor family. They use partially common signaling molecules leading, among others, to activation of the NF-kappaB pathway. However, whereas TNF activates the classical, CD40L has been reported to activate the alternative NF-kappaB pathway, leading to the anticipation that differences in the pattern of inflammatory gene expression would occur. Here, we have compared the gene expression repertoire of CD40L (CD154) and TNF stimulated HUVEC and report that unexpectedly, apart from a stronger response to TNF, no major qualitative differences could be observed. This applies for the period of up to 6 h, a time where the alternative pathway has already been activated. Analysis of the early events after receptor engagement revealed that both TNF and CD40L activate the classical NF-kappaB pathway, and confirm activation of the alternative by the latter. Furthermore, using genetic and pharmacological inhibition of the classical pathway we show that activation of the alternative occurs independently of the former. This reveals novel insights into NF-kappaB signaling by CD40L and TNF in endothelial cells. PMID- 29183725 TI - Involuntary swimming exercise in pregnant rats disturbs ERK1/2 signaling in embryonic neurons through increased cortisol in the amniotic fluid. AB - Harmful maternal behaviors, such as drinking and smoking, negatively affect embryonic development. In contrast, regular maternal exercise is believed to be beneficial to the fetus. Although it is not surprising that voluntary physical activities are advantageous to fetal development, it remains unclear whether involuntary maternal exercise has similar effects. The constituents of the amniotic fluid (AF) inevitably reflect the maternal plasma. Therefore, it is speculated that exercise-induced changes in maternal plasma can influence fetal development through changes in AF composition. Therefore, we investigated the effect of AF on fetal neurodevelopment and changes in AF composition after involuntary swimming exercise (SE) in an animal model. We found that there was a severe reduction in the number of embryos implanted in the uterus of SE rats. Surprisingly, cortisol level (an inducible stress hormone) was significantly increased in AF from SE rats. In contrast, the growth factors NGF and VEGF were reduced in the AF from SE rats. In the cultured embryonic cortical neurons, the treatment of control (CTL) rat-derived AF significantly increased the phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2)-mediated signaling that is essential for fetal neurodevelopment. However, the AF extracted from SE rats reversely suppressed the phosphorylation of ERK1/2-mediated signaling in cortical neurons compared to that in CTL rats. Indeed, the co treatment with control AF and dexamethasone, a synthetic glucocorticoid, inhibited the phosphorylation of ERK1/2 in a dose-dependent manner. This finding suggests that the inhibition of ERK1/2 can be attributed to increased cortisol level in AF resulting from involuntary exercise. Therefore, involuntary maternal swimming increases cortisol level in AF, which ultimately hinders the ERK1/2 signaling pathway in embryonic neurons. These findings also suggest that involuntary maternal exercise can have undesirable effects on fetal neurodevelopment, which is potentially mediated by elevated AF cortisol level. PMID- 29183726 TI - GSDME mediates caspase-3-dependent pyroptosis in gastric cancer. AB - Gastric cancer is a malignancy that starts from the cells in the stomach with relatively low overall survival rate. Chemotherapy following resection surgery has been recommended as a curative strategy for gastric cancer. However, the mechanism of the chemotherapy drugs on gastric cancer is not completely understood. Pyroptosis is a form of programmed cell death and plays critical role in immunity. The role of pyroptosis on cancer cells is less known. In this study, we treated SGC-7901 and MKN-45 with 5-FU and found that the cell viability was significantly decreased. The release of LDH and the percentage of PI and APC Annexin-V double positive cells after 5-FU treatment were elevated compared to control group. Moreover, there were large bubbles blowing from the membrane of 5 FU-treated cells and the cleavage of GSDME but not GSDMD, which were blocked by the silence or specific inhibitor of caspase-3. Additionally, GSDME knockout by CRISPR-Cas9 switched 5-FU induced pyroptosis into apoptosis in SGC-7901. In conclusion, our findings firstly revealed that GSDME switches chemotherapy drug induced caspase-3 dependent apoptosis into pyroptosis in gastric cancer cells. PMID- 29183727 TI - Resveratrol strongly enhances the retinoic acid-induced superoxide generating activity via up-regulation of gp91-phox gene expression in U937 cells. AB - The membrane bound cytochrome b558 composed of gp91-phox and p22-phox proteins, and cytosolic proteins p40-, p47-and p67-phox are important components of superoxide (O2-)-generating system in phagocytes. Here, we describe that resveratrol, a pleiotropic phytochemical belonging to the stilbenoids, dramatically activates the O2--generating system during retinoic acid (RA) induced differentiation of human monoblastic leukemia U937 cells to macrophage like cells. When U937 cells were cultured in the presence of RA and resveratrol, the O2--generating activity increased more than 5-fold compared with that in the absence of the latter. Semiquantitative RT-PCR showed that co-treatment with RA and resveratrol strongly enhanced transcription of the gp91-phox compared with those of the RA-treatment only. On the other hand, immunoblot analysis revealed that co-treatment with RA and resveratrol caused remarkable accumulation of protein levels of gp91-phox (to 4-fold), p22-phox (to 5-fold) and p47-phox (to 4 fold) compared with those of the RA-treatment alone. In addition, ChIP assay suggested that resveratrol participates in enhancing the gene expression of gp91 phox via promoting acetylation of Lys-9 residues and Lys-14 residues of histone H3 within chromatin around the promoter regions of the gene. These results suggested that resveratrol strongly enhances the RA-induced O2--generating activity via up-regulation of gp91-phox gene expression in U937 cells. PMID- 29183728 TI - Lycium barbarum polysaccharide protects against oxygen glucose deprivation/reoxygenation-induced apoptosis and autophagic cell death via the PI3K/Akt/mTOR signaling pathway in primary cultured hippocampal neurons. AB - Lycium barbarum polysaccharide (LBP) is the main active ingredient of Lycium barbarum, which exhibits several beneficial effects, including neuroprotection, anti-aging and anti-oxidation. However, the mechanism by which LBP protects against cerebral ischemia/reperfusion-induced injury remains obscure. In this study, we found that LBP pretreatment greatly attenuated oxygen glucose deprivation/reperfusion (OGD/R) injury in primary cultured hippocampal neurons. LBP also suppressed OGD/R-induced lactate dehydrogenase (LDH) leakage, and ameliorated oxidative stress. In addition, LBP significantly reduced OGD/R induced apoptosis and autophagic cell death. LBP caused the down-regulation of cleaved Caspase-3/Caspase-3, LC3II/LC3I and Beclin 1, as well as up-regulation of Bcl-2/Bax and p62. Furthermore, mechanistic studies indicated that LBP pretreatment increased p-Akt and p-mTOR levels after OGD/R. In summary, our results indicated that LBP protects against OGD/R-induced neuronal injury in primary hippocampal neurons by activating the PI3K/Akt/mTOR signaling pathway. PMID- 29183729 TI - miR-596 Modulates Melanoma Growth by Regulating Cell Survival and Death. AB - Tumors grow because cancer cells lack the ability to balance cell survival and death signaling pathways. miR-596, a microRNA located at the 8p23.3 locus, has been shown by the TCGA-Assembler to be deleted in a significant number of melanoma samples. Here, we also validated the low levels of miR-596 in melanoma compared to tissue nevi, and Kaplan-Meier curve analysis revealed that low miR 596 expression was associated with worse overall survival. Moreover, we showed that miR-596 overexpression effectively inhibited MAPK/ERK signaling, cell proliferation, migration, and invasion and increased the cell apoptosis of melanoma cells. In addition, we found that miR-596 directly targets MEK1 and two apoptotic proteins, MCL1, and BCL2L1, in melanoma cells. Our findings indicated that miR-596 is an important miRNA that both negatively regulates the MAPK/ERK signaling pathway by targeting MEK1 and modulates the apoptosis pathway by targeting MCL1 and BCL2L1, suggesting that miR-596 could be a therapeutic candidate for treating melanoma, and a prognostic factor for melanoma patients. PMID- 29183730 TI - Aging-Associated Decline of Epidermal PSMD8 Contributes to Impaired Skin Function. PMID- 29183733 TI - Measles and rubella eradication. AB - This article discusses concepts of eradication, some issues relating to vertical and horizontal public health programs, some current issues relating to measles and rubella, and what we need to do about them. It concludes that measles and rubella/CRS can and should be eradicated. A target date should be established in 2020 (or before). Eradication can only be accomplished in the context of strengthening ongoing immunization services and strengthening surveillance so it can guide activities. Additional resources will be required to achieve the goal. PMID- 29183731 TI - Intentional and Unintentional Medication Non-Adherence in Psoriasis: The Role of Patients' Medication Beliefs and Habit Strength. AB - Medication non-adherence is a missed opportunity for therapeutic benefit. We assessed "real-world" levels of self-reported non-adherence to conventional and biologic systemic therapies used for psoriasis and evaluated psychological and biomedical factors associated with non-adherence using multivariable analyses. Latent profile analysis was used to investigate whether patients can be categorized into groups with similar medication beliefs. Latent profile analysis categorizes individuals with similar profiles on a set of continuous variables into discrete groups represented by a categorical latent variable. Eight hundred and eleven patients enrolled in the British Association of Dermatologists Biologic Interventions Register were included. Six hundred and seventeen patients were using a self-administered systemic therapy; 22.4% were classified as "non adherent" (12% intentionally and 10.9% unintentionally). Patients using an oral conventional systemic agent were more likely to be non-adherent compared to those using etanercept or adalimumab (29.2% vs. 16.4%; P <= 0.001). Latent profile analysis supported a three-group model; all groups held strong beliefs about their need for systemic therapy but differed in levels of medication concerns. Group 1 (26.4% of the sample) reported the strongest concerns, followed by Group 2 (61%), with Group 3 (12.6%) reporting the weakest concerns. Group 1 membership was associated with intentional non-adherence (odds ratio = 2.27, 95% confidence interval = 1.16-4.47) and weaker medication-taking routine or habit strength was associated with unintentional non-adherence (odds ratio = 0.92, 95% confidence interval = 0.89-0.96). Medication beliefs and habit strength are modifiable targets for strategies to improve adherence in psoriasis. PMID- 29183732 TI - Role of rotavirus vaccination on an emerging G8P[8] rotavirus strain causing an outbreak in central Japan. AB - BACKGROUND: In this study, we examined the effectiveness of RV1 and RV5 vaccines during an outbreak of G8P[8] rotavirus group A strain (G8P[8]-RVA). These vaccines were originally designed to provide protection against severe diseases caused by common circulating strains, whereas G8P[8]-RVA remains emerging strain and partially heterotypic to the vaccines. It is imperative to investigate vaccine effectiveness (VE) against G8P[8]-RVA because this strain appears to be predominant in recent years, particularly, in post-vaccine era. METHODS: RVA infection and genotypes were confirmed by polymerase chain reaction (PCR) followed by sequence-based genotyping. VE was determined during an outbreak of G8P[8]-RVA in Shizuoka Prefecture, Japan, in February-July 2017, retrospectively, by comparing vaccination status of children suffering from acute gastroenteritis (AGE) between 'PCR-positive' and 'PCR-negative' cases using conditional logistic regression adjusted for age. RESULTS: Among 80 AGE children, RVA was detected in 58 (73%), of which 53 (66%) was G8P[8]-RVA. The clinical characteristics of G8P[8]-RVA and other RVA strains were identically severe. Notably, the attack rates of G8P[8]-RVA in vaccinated (61.1%) and unvaccinated (65.5%) children were almost similar. Indeed, no substantial effectiveness were found against G8P[8] RVA (VE, 14% [95% CI: -140% to 70%]) or other RVA strains (VE, 58% [95% CI: -20% to 90%]) for mild infections. However, these vaccines remained strongly effective against moderate (VE, 75% [95% CI: 1% to 40%]) and severe (VE, 92% [95% CI: 60% to 98%]) RVA infections. The disease severity including Vesikari score, duration and frequency of diarrhea, and body temperature were significantly lower in vaccinated children. CONCLUSIONS: This study demonstrates the effectiveness of current RV vaccines against moderate and severe, but not against the mild infections during an outbreak caused by unusual G8P[8]-RVA, which was virtually not targeted in the vaccines. PMID- 29183734 TI - Immune memory at 17-years of follow-up of a single dose of live attenuated hepatitis A vaccine. AB - BACKGROUND: In recent years, hepatitis A virus (HAV) infection has declined considerably in China, associated with wide deployment of HAV vaccines and improvement in socio-economic indicators. Towards the elimination of HA in the country, we assessed the duration and characteristics of immunity conferred by the widely used, locally manufactured HAV vaccine. METHODS: This is a longitudinal cohort study that followed recipients of a live attenuated HAV vaccine 17 years after the initial administration. Blood samples were collected from participants pre- and two-week post-booster HAV vaccine dose. Serum anti-HAV antibody was measured by ELISA method. Memory B and T cells were determined by ELISPOT and Flow Cytometry assays, respectively. RESULTS: A robust anamnestic response was observed two-week post-challenge. Both HAV-specific memory B cell and T cells remained, and responded quickly when re-encountering HAV. The magnitude of recall responses was present, regardless of the status of the serum anti-HAV antibody pre-booster. CONCLUSIONS: We demonstrated long-term immunity from the live attenuated HAV vaccine, including antibody persistence and immunological memory. Considering the conditions that make elimination of infectious diseases feasible, following polio, hepatitis A could be targeted for elimination in China. PMID- 29183736 TI - Immunotherapy in the Elderly. AB - CONTEXT: Immunotherapy has historic and contemporary presence in prostate, urothelial (UC), and renal cell (RCC) carcinomas. However, robust data on utility and generalizability of these treatments in older patients are lacking. OBJECTIVE: To systematically evaluate evidence regarding the efficacy and safety of immunotherapy in elderly patients with prostate cancer, UC, or RCC. EVIDENCE ACQUISITION: PubMed/Medline, Embase, Web of Knowledge, and Cochrane Library databases were searched up to October 2017 and according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. A narrative review of studies was performed. EVIDENCE SYNTHESIS: Twenty-one reports were included regarding prostate cancer (four studies), UC (eight), and RCC (nine). In prostate cancer, sipuleucel-T improves survival (median age >70 yr) and similar results were seen in the PROSTVAC phase 2 trial. Ipilimumab has not improved survival independent of age; data for programmed cell death 1 inhibition is evolving. In metastatic UC, >=50% of patients enrolled in pivotal checkpoint inhibitor studies were aged >=65 yr. Three studies reported similar objective response rates (ORRs) in patients aged <65 versus >=65 yr, whereas one study reported comparable ORRs in patients <80 versus >=80 yr. In metastatic RCC, cytokine studies showed no efficacy difference by age; one study reported more >=grade 3 toxicity in patients aged >=65 yr. One vaccine-based study suggests that older age was associated with shorter survival. The benefit of nivolumab in second-line therapy was more apparent for patients aged 65-<75 yr than for those aged >=75 yr. Across tumor subtypes, immunotherapy was well tolerated with minimal data stratifying toxicity by age. CONCLUSIONS: Contemporary immunotherapy has informed practice in genitourinary malignancies independent of patient age. Trial reporting of outcomes by age will be important to understand the generalizability of ongoing investigations for elderly patients. PATIENT SUMMARY: With the growing use of immunotherapy in genitourinary malignancies, benefits appear to apply independent of age. As the field advances, detailed reporting on outcomes and toxicities by age will be informative for both patients and physicians when discussing treatment options. PMID- 29183735 TI - Meningococcal carriage among a university student population - United States, 2015. AB - OBJECTIVES: Several outbreaks of serogroup B meningococcal disease have occurred among university students in recent years. In the setting of high coverage of the quadrivalent meningococcal conjugate vaccine and prior to widespread use of serogroup B meningococcal vaccines among adolescents, we conducted surveys to characterize the prevalence and molecular characteristics of meningococcal carriage among university students. METHODS: Two cross-sectional oropharyngeal carriage surveys were conducted among undergraduates at a Rhode Island university. Isolates were characterized using slide agglutination, real-time polymerase chain reaction (rt-PCR), and whole genome sequencing. Adjusted prevalence ratios and 95% confidence intervals were calculated using Poisson regression to determine risk factors for carriage. RESULTS: A total of 1837 oropharyngeal specimens were obtained from 1478 unique participants. Overall carriage prevalence was 12.7-14.6% during the two survey rounds, with 1.8-2.6% for capsular genotype B, 0.9-1.0% for capsular genotypes C, W, or Y, and 9.9 10.8% for nongroupable strains by rt-PCR. Meningococcal carriage was associated with being male, smoking, party or club attendance, recent antibiotic use (inverse correlation), and recent respiratory infections. CONCLUSIONS: In this university setting, the majority of meningococcal carriage was due to nongroupable strains, followed by serogroup B. Further evaluation is needed to understand the dynamics of serogroup B carriage and disease among university students. PMID- 29183737 TI - Cross-platform single cell analysis of kidney development shows stromal cells express Gdnf. AB - The developing kidney provides a useful model for study of the principles of organogenesis. In this report we use three independent platforms, Drop-Seq, Chromium 10x Genomics and Fluidigm C1, to carry out single cell RNA-Seq (scRNA Seq) analysis of the E14.5 mouse kidney. Using the software AltAnalyze, in conjunction with the unsupervised approach ICGS, we were unable to identify and confirm the presence of 16 distinct cell populations during this stage of active nephrogenesis. Using a novel integrative supervised computational strategy, we were able to successfully harmonize and compare the cell profiles across all three technological platforms. Analysis of possible cross compartment receptor/ligand interactions identified the nephrogenic zone stroma as a source of GDNF. This was unexpected because the cap mesenchyme nephron progenitors had been thought to be the sole source of GDNF, which is a key driver of branching morphogenesis of the collecting duct system. The expression of Gdnf by stromal cells was validated in several ways, including Gdnf in situ hybridization combined with immunohistochemistry for SIX2, and marker of nephron progenitors, and MEIS1, a marker of stromal cells. Finally, the single cell gene expression profiles generated in this study confirmed and extended previous work showing the presence of multilineage priming during kidney development. Nephron progenitors showed stochastic expression of genes associated with multiple potential differentiation lineages. PMID- 29183738 TI - isGPT: An optimized model to identify sub-Golgi protein types using SVM and Random Forest based feature selection. AB - The Golgi Apparatus (GA) is a key organelle for protein synthesis within the eukaryotic cell. The main task of GA is to modify and sort proteins for transport throughout the cell. Proteins permeate through the GA on the ER (Endoplasmic Reticulum) facing side (cis side) and depart on the other side (trans side). Based on this phenomenon, we get two types of GA proteins, namely, cis-Golgi protein and trans-Golgi protein. Any dysfunction of GA proteins can result in congenital glycosylation disorders and some other forms of difficulties that may lead to neurodegenerative and inherited diseases like diabetes, cancer and cystic fibrosis. So, the exact classification of GA proteins may contribute to drug development which will further help in medication. In this paper, we focus on building a new computational model that not only introduces easy ways to extract features from protein sequences but also optimizes classification of trans-Golgi and cis-Golgi proteins. After feature extraction, we have employed Random Forest (RF) model to rank the features based on the importance score obtained from it. After selecting the top ranked features, we have applied Support Vector Machine (SVM) to classify the sub-Golgi proteins. We have trained regression model as well as classification model and found the former to be superior. The model shows improved performance over all previous methods. As the benchmark dataset is significantly imbalanced, we have applied Synthetic Minority Over-sampling Technique (SMOTE) to the dataset to make it balanced and have conducted experiments on both versions. Our method, namely, identification of sub-Golgi Protein Types (isGPT), achieves accuracy values of 95.4%, 95.9% and 95.3% for 10 fold cross-validation test, jackknife test and independent test respectively. According to different performance metrics, isGPT performs better than state-of the-art techniques. The source code of isGPT, along with relevant dataset and detailed experimental results, can be found at https://github.com/srautonu/isGPT. PMID- 29183739 TI - Characterization of a novel GH36 alpha-galactosidase from Bacillus megaterium and its application in degradation of raffinose family oligosaccharides. AB - A novel alpha-galactosidase gene (agaB) from Bacillus megaterium 3-7 was cloned and expressed in Escherichia coli. The gene coded for a protein with 741 amino acids and a calculated molecular mass of 85.4kDa. The native structure of the recombined AgaB was determined to be a homotrimer. AgaB showed the highest identity of 57% with the characterized glycosyl hydrolase family 36 alpha galactosidase from Clostridium stercorarium F-9. The enzyme exhibited a specific activity of 362.6U/mg at 37 degrees C and pH 6.8. The enzyme showed strong resistance to proteases and great tolerance to galactose (Ki=12.5mM). AgaB displayed wide substrate specificity toward pNPGal, melibiose, raffinose and stachyose, with a Km of 0.42, 12.1, 17.0 and 25.4mM, respectively. Furthermore, AgaB completely hydrolyzed raffinose and stachyose present in soybean milk at 37 degrees C within 4h when combined with trypsin. These favorable properties make AgaB a potential candidate for applications in the food and feed industries. PMID- 29183740 TI - Facile immobilization of Bacillus licheniformis gamma-glutamyltranspeptidase onto graphene oxide nanosheets and its application to the biocatalytic synthesis of gamma-l-glutamyl peptides. AB - For the practical application of Bacillus licheniformis gamma glutamyltranspeptidase (BlGGT), we illustrated a simple and efficient approach to fabricate a biocatalytic system by immobilizing the enzyme onto graphene oxide (GO) nanosheets via both non-covalent (GO-BlGGT) and covalent (GO/GA-BlGGT) bonds. The enzyme-loading capacity for the prepared GO/GA nanomaterial was 3.47 mg/mg support, corresponding to 68.7% recovery of the initial activity. Native and enzyme-bound layered GOs were characterized by X-ray diffraction, followed by Raman and Fouier transform infrared spectroscopy, elemental analysis and thermogram analysis. As compared to the free form of BlGGT, the immobilized enzymes exhibited significantly higher activity, possibly due to the beneficial effect of the layered GO carrier. The kinetic behaviors of GO-BlGGT and GO/GA BlGGT were mostly consistent with those of free enzyme. The covalently immobilized enzyme had a comparable stability respective to free enzyme during a storage period of 30 days and could be recycled nine times with 45.3% retention of the initial activity. Besides, the biocatalytic synthesis of gamma-l-glutamyl phenylalanine and gamma-l-glutamyl-leucine by immobilized enzymes resulted in the product yield of more than 31%. Taken together, these results suggest that the facile strategy is an economical means of depositing bioactive enzymes upon GO nanosheets for BlGGT-mediated biocatalysis. PMID- 29183741 TI - Arginine as an Excipient for Protein Freeze-Drying: A Mini Review. AB - Successful development of marketable freeze-dried protein formulations requires adequate stabilization of the active biopharmaceutical ingredient. The choice of a stabilizer must therefore be based on sound knowledge of the physical and chemical properties of the excipients and specific needs of the protein component. Amino acids, such as arginine, have exhibit cryo- and lyoprotective effects similar to those of sugars and polymers and may therefore be considered to be an alternative approach to these established formulation strategies. The chemical structure and physicochemical characteristics of arginine are unique among amino acids and can provide additional benefits to freeze-dried protein formulations with regard to liquid and solid-state stability. This mini review provides a brief summary of research focused on the application of arginine in freeze-dried protein pharmaceuticals, including a discussion of its basic physical and chemical attributes as well as thermal behavior in the frozen and solid states. Mechanisms contributing to solid-state stabilization by arginine are discussed in the context of available stability studies on arginine containing protein formulations. This mini review seeks to deepen the understanding of the opportunities and challenges associated with arginine-based preparations for freeze-dried protein pharmaceuticals. PMID- 29183742 TI - Curcumin Cocrystal Micelles-Multifunctional Nanocomposites for Management of Neurodegenerative Ailments. AB - Curcumin, a potent antioxidant polyphenol with neuroprotective and antiamyloid activities, has significant potential in the treatment of neurodegenerative disorders such as Alzheimer's disease. However, its clinical translation is delayed due to poor bioavailability. For effective use of curcumin in Alzheimer's disease, it is imperative to increase its bioavailability with enhanced delivery at a therapeutic site that is, brain. With this objective, pharmaceutical cocrystals of curcumin were developed and incorporated in micellar nanocarriers for nose-to-brain delivery. For cocrystals, an antioxidant hydrophilic coformer was strategically selected using molecular modeling approach. The cocrystals were formulated using a planetary ball mill, and the process was optimized using 32 factorial design followed by characterization using differential scanning calorimetry, X-ray diffraction, and Fourier-transform infrared spectroscopy analysis. The cocrystal micelles exhibited globule size of 28.79 +/- 0.86 nm. Further, curcumin cocrystal and co-crystal micelles exhibited a significantly low (p value <0.01) IC50 concentration for antioxidant activity as compared to curcumin corroborating superior antioxidant performance. In vivo studies revealed about 1.7-fold absolute bioavailability of curcumin cocrystal micelles with Cmax of 1218.38 +/- 58.11 ng/mL and showed significantly high brain distribution even beyond 6 hours of dosing. Thus, the studies confirmed enhanced bioavailability, higher brain uptake, retention, and delayed clearance with curcumin cocrystal micellar nanocarriers. PMID- 29183743 TI - Development and Characterization of Chitosan Cross-Linked With Tripolyphosphate as a Sustained Release Agent in Tablets, Part I: Design of Experiments and Optimization. AB - Certain issues with the use of particles of chitosan (Ch) cross-linked with tripolyphosphate (TPP) in sustained release formulations include inefficient drug loading, burst drug release, and incomplete drug release. Acetaminophen was added to Ch:TPP particles to test for advantages of drug addition extragranularly over drug addition made during cross-linking. The influences of Ch concentration, Ch:TPP ratio, temperature, ionic strength, and pH were assessed. Design of experiments allowed identification of factors and 2-factor interactions that have significant effects on average particle size and size distribution, yield, zeta potential, and true density of the particles, as well as drug release from the directly compressed tablets. Statistical model equations directed production of a control batch that minimized span, maximized yield, and targeted a t50 of 90 min (sample A); sample B that differed by targeting a t50 of 240-300 min to provide sustained release; and sample C that differed from sample B by maximizing span. Sample B maximized yield and provided its targeted t50 and the smallest average particle size, with the higher zeta potential and the lower span of samples B and C. Extragranular addition of a drug to Ch:TPP particles achieved 100% drug loading, eliminated a burst drug release, and can accomplish complete drug release.

AB - Cutaneous minoxidil (MXD) formulations were developed with the intent to reduce the side effects of the cosolvents propylene glycol and ethanol, frequently used in commercial MXD solutions. Completely aqueous alginate-based hydrogels were investigated and MXD aqueous solubility was improved using inclusion complexes with hydroxypropyl-beta-cyclodextrin (HP-beta-CD) at 2 different molar substitution degree (MS), namely 0.65 and 0.85. HP-beta-CD MS 0.65 was selected for its improved solubilizing ability toward MXD. At concentration of 39% w/v, this cyclodextrin increased the intrinsic aqueous solubility of MXD of about 22 fold. The calculated complexation constant was 2309 +/- 20 M-1, and the inclusion process was spontaneous and enthalpically driven. Nuclear magnetic resonance studies (Job plot, 1H, 2D correlations spectroscopy, nuclear overhauser effect spectroscopy, and rotating-frame overhauser enhancement spectroscopy) confirmed the stoichiometry 1:1 between MXD and HP-beta-CD providing information about the exact geometry of the inclusion complex. Rheological and in vitro release studies performed on the formulation loaded with MXD 3.5% w/w proved that the inclusion complex increased the viscosity of the hydrogel modulating the release of the free drug. Furthermore, the hydrogel formulation facilitate MXD to permeate into the skin and did not damage epidermis, suggesting that these completely aqueous MXD delivery systems can be proposed as alternative formulations to commercial solutions.

AB - Four new 4,5-dihydro-1,3-oxazole, and four new benzo-[d]-oxazole derivatives of [17(20)E]-21-norpregnene, differing in the structure of steroid moiety, were synthesized and evaluated for their potency to inhibit 17alpha-hydroxylase/17,20 lyase (CYP17A1) activity. Among new compounds, the only oxazolinyl derivative comprising 5-oxo-4,5-seco-3-yn- moiety potently inhibited CYP17A1. Binding modes of the oxazolinyl derivatives of [17(20)E]-21-norpregnene were analyzed by molecular dynamics simulations, and model of alternate, water-bridged type II interaction was proposed for these compounds. Eight new compounds, together with two CYP17A1-inhibiting oxazolinyl derivatives synthesized earlier, abiraterone and galeterone were evaluated for their potency to inhibit prostate carcinoma PC 3 and LNCaP cells growth. Oxazolinyl and benzoxazolyl derivatives comprising 3beta-hydroxy-5-ene moieties potently inhibited prostate carcinoma cell growth; inhibitory potencies of 3-oxo-4-en- and 5-oxo-4,5-seco-3-yn- derivatives were significantly lower. PMID- 29183746 TI - Assessment of the anti-snakebite properties of extracts of Aniba fragrans Ducke (Lauraceae) used in folk medicine as complementary treatment in cases of envenomation by Bothrops atrox. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Extracts of leaves and bark of Aniba fragrans are used as tea (decoction) to treat snakebites in communities in the Brazilian Amazon. The aqueous extract of the leaves of A. fragrans has been proven to be effective against Bothrops venom, but only when pre-incubated with the venom. This study sought to assess the potential of different types of extract of this species to inhibit the biological activities of Bothrops atrox venom (BaV) when used the same way as in folk medicine. The main classes of secondary metabolites and the concentrations of phenolics in the extracts were also determined. MATERIALS AND METHODS: Four types of extract of A. fragrans were prepared: aqueous extract of the leaf (AEL), aqueous extract of the bark (AEB), hydroalcoholic leaf extract (HLE) and extract of the residue from hydrodistillation of the leaf (ERHL). The phytochemical profiles of the aqueous extracts were determined using thin layer chromatography (TLC), and the concentrations of phenolics were measured by colorimetric assays. To investigate the potential of the extracts to inhibit the biological activities of BaV, in vitro tests for antiphospholipase and antifibrinolytic activities were performed. In vivo tests for antihemorrhagic and antidefibrinating activities were also carried out, as well as antimicrobial tests for activity against the main bacteria found in the oral cavity of snakes. Interaction between the extracts and the proteins in BaV was assessed by electrophoresis (SDS-PAGE) and Western blot (WB). The cytotoxicity of the extracts was assessed in a strain of MRC-5 human fibroblasts. RESULTS: Terpenoids, flavonoids and condensed and hydrolysable tannins were detected in all the extracts. Metabolites such as coumarins, fatty acids and alkaloids were present in some extracts but not in others, indicating different phytochemical profiles. Phenolics content varied between extracts, and there were more tannins in AEB and HLE. In the in vitro tests, the extracts inhibited the phospholipase and fibrinolytic activities of BaV in the two ratios of venom to extract used. HLE exhibited effective antimicrobial action as it inhibited growth of 11 of the 15 bacteria investigated, including Morganella morganii, the main bacteria described in the oral cavity of snakes. The extracts failed to inhibit the defibrinating activity of BaV, and only the Bothrops antivenom had a significant effect (96.1%) on this activity. BaV-induced hemorrhage was completely inhibited by AEL and AEB when the pre-incubation (venom:extract) protocol was used. When administered orally, as in folk medicine, both AEB and AEL produced significant inhibition of hemorrhagic activity (maximum inhibition 46.5% and 39.2%, respectively). SDS-PAGE and WB of the extracts pre incubated with BaV showed that the main proteins in the venom had been precipitated by the extracts. None of the four extracts showed cytotoxic effects in the tests carried out with a human fibroblast cell line. CONCLUSION: In addition to being effective in reducing hemorrhage when administered orally, the extracts displayed a high antimicrobial potential against microorganisms involved in secondary infections at the site of the snakebite. Once the extracts have been tested in accordance with the appropriate regulations, this species could potentially be used to produce a phytomedicine for complementary treatment of the secondary infections due to bacteria that aggravate the local signs and symptoms after snakebite envenomation. PMID- 29183747 TI - Anticonvulsant effect of the hydroethanolic leaf extract of Psydrax subcordata (DC.) Bridson in murine models. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Psydrax subcordata (DC.) Bridson is a tropical medicinal plant used traditionally for the management of epilepsy. However, there is little scientific evidence to support its use. AIM OF STUDY: The current study investigated the anticonvulsant properties of the hydroethanolic leaf extract of Psydrax subcordata (PSE) in animal models. MATERIALS AND METHODS: The anticonvulsant effects were evaluated in mouse models of acute seizures (pentylenetetrazole-, picrotoxin-, 4-aminopyridine-, strychnine- and maximal electroshock-induced seizure tests) and status epilepticus (Lithium/pilocarpine induced SE). The role of GABAergic mechanisms in the actions of the extract was also examined by pre-treatment of animals with flumazenil in the pentylenetetrazole test. RESULTS: The extract (30, 100 and 300mg/kg, p.o.) significantly delayed the onset and decreased the duration and frequency of pentylenetetrazole- and picrotoxin-convulsions. PSE also reduced the duration of tonic hind limb extensions in the maximal electroshock-induced seizure test. Furthermore, PSE pre-treatment significantly delayed the onset of seizures and improved survival in the 4-aminopyridine-induced seizure test. In the strychnine induced seizure test, PSE treatment did not significantly affect the latency to convulsions and time until death when compared to controls. PSE exhibited anticonvulsant effects in the lithium/pilocarpine test by delaying the onset of seizures and status epilepticus as well as reducing the severity of seizures and mortality of mice. Again, the anticonvulsant effect of PSE (100mg/kg, p.o.) was blocked by pre-treatment with flumazenil in the PTZ test. CONCLUSION: PSE has anticonvulsant activity in animal models, and this effect may be mediated, at least partly, through GABAergic mechanisms.

PMID- 29183749 TI - Heterologous transporter expression for improved fatty alcohol secretion in yeast. AB - The yeast Saccharomyces cerevisiae is an attractive host for industrial scale production of biofuels including fatty alcohols due to its robustness and tolerance towards harsh fermentation conditions. Many metabolic engineering strategies have been applied to generate high fatty alcohol production strains. However, impaired growth caused by fatty alcohol accumulation and high cost of extraction are factors limiting large-scale production. Here, we demonstrate that the use of heterologous transporters is a promising strategy to increase fatty alcohol production. Among several plant and mammalian transporters tested, human FATP1 was shown to mediate fatty alcohol export in a high fatty alcohol production yeast strain. An approximately five-fold increase of fatty alcohol secretion was achieved. The results indicate that the overall cell fitness benefited from fatty alcohol secretion and that the acyl-CoA synthase activity of FATP1 contributed to increased cell growth as well. This is the first study that enabled an increased cell fitness for fatty alcohol production by heterologous transporter expression in yeast, and this investigation indicates a new potential function of FATP1, which has been known as a free fatty acid importer to date. We furthermore successfully identified the functional domain of FATP1 involved in fatty alcohol export through domain exchange between FATP1 and another transporter, FATP4. This study may facilitate a successful commercialization of fatty alcohol production in yeast and inspire the design of novel cell factories. PMID- 29183750 TI - Pheromone-inducible expression vectors for fission yeast Schizosaccharomyces pombe. AB - The fission yeast Schizosaccharomyces pombe is an attractive host for heterologous gene expression. However, expression systems for industrially viable large-scale fermentations are scarce. Several inducible expression vectors for S. pombe have been reported, with the strong thiamine-repressible nmt1+ promoter or derivatives thereof most commonly employed. Previously, the promoter regions of the genes sxa2+ and rep1+ were utilized to couple pheromone signaling to the expression of reporter genes for quantitative assessment of the cellular response to mating pheromones. Here, we exploit these promoters to serve as highly effective, plasmid-based inducible expression systems for S. pombe. Simply by adding synthetic P-factor pheromone, both promoters conferred 50-60% higher peak expression levels than the nmt1+ promoter. Full induction was significantly faster than observed for nmt1+-based expression platforms. Furthermore, the sxa2+ promoter showed very low basal activity and an overall 584-fold induction by synthetic P-factor pheromone. The dose-response curves of both promoters were assessed, providing the opportunity for facile tuning of the expression level by modulating P-factor concentration. Since the expression plasmids relying on the sxa2+ and rep1+ promoters require neither medium exchange nor glucose/thiamine starvation, they proved to be very convenient in handling. Hence, these expression vectors will improve the palette of valuable genetic tools for S. pombe, applicable to both basic research and biotechnology.

AB - OBJECTIVE: To examine differences in long-term social reintegration outcomes for burn survivors with and without work-related injuries. DESIGN: Cross-sectional survey. SETTING: Community-dwelling burn survivors. PARTICIPANTS: Burn survivors (N=601) aged >=18 years with injuries to >=5% total body surface area or burns to critical areas (hands, feet, face, or genitals). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Life Impact Burn Recovery Evaluation Profile was used to examine the following previously validated 6 scale scores of social participation: Family and Friends, Social Interactions, Social Activities, Work and Employment, Romantic Relationships, and Sexual Relationships. RESULTS: Older participants, those who were married, and men were more likely to be burned at work (P<.01). Burn survivors who were injured at work scored significantly lower on the Work and Employment scale score after adjusting for demographic and clinical characteristics (P=.01). All other domain scale scores demonstrated no significant differences between groups. Individuals with work-related injuries scored significantly worse on 6 of the 19 items within the Work and Employment scale (P<.05). These individuals were more likely to report that they were afraid to go to work and felt limited in their ability to perform at work. CONCLUSIONS: Burn survivors with work-related injuries report worse work reintegration outcomes than those without work-related injuries. Identification of those at higher risk for work reintegration challenges after burn injury may enable survivors, providers, employers, and insurers to better use appropriate resources to promote and target optimal employment outcomes. PMID- 29183752 TI - One-Year Comparison of a Community-Based Exercise Program Versus a Day Hospital Based Exercise Program on Quality of Life and Mental Health in Severely Burned Children. AB - OBJECTIVE: To compare the effects of long-term psychosocial functioning and mental health of a "day hospital"-based exercise program (DAYEX) versus a community-based exercise program (COMBEX). DESIGN: A prospective design that consisted of 2 groups (DAYEX and COMBEX). SETTING: A children's hospital specialized in burn care. PARTICIPANTS: Patients (N=18; DAYEX [n=9], COMBEX [n=9]) were assessed at intensive care unit discharge and up to 1 year postburn. INTERVENTIONS: The Child Health Questionnaires (CHQ-Child Form [CHQ-CF87] and CHQ Parent Form [CHQ-PF28]) were used to assess changes in quality of life from discharge to 1 year postburn. MAIN OUTCOME MEASURES: CHQ-PF28 and CHQ-CF87. RESULTS: Demographic characteristics and total body surface area burned were similar in both groups. Length of hospital stay was significant in the COMBEX group. CHQ-CF87 and CHQ-PF28 documented significant improvements in both groups between discharge and 1 year. Significance was evident in Physical Functioning, Bodily Pain, Self-Esteem, Change in Health, and Family Activities. CHQ-CF87 showed improvement in Family Cohesion in COMBEX more than DAYEX. CHQ-PF28 showed improvement in Role/Social Limitations-Emotional, Bodily Pain, and Family Activities in COMBEX more than DAYEX. CONCLUSIONS: The proposed COMBEX program is feasible and beneficial physically, psychosocially, and mentally. The results show some improvements in the COMBEX group in optimizing function and health in severely burned children. The COMBEX group performed at least as well as the DAYEX group. Larger-scale studies are needed to validate current findings. PMID- 29183753 TI - Xanthine-derived KMUP-1 reverses glucotoxicity-activated Kv channels through the cAMP/PKA signaling pathway in rat pancreatic beta cells. AB - Hyperglycemia-associated glucotoxicity induces beta-cell dysfunction and a reduction in insulin secretion. Voltage-dependent K+ (Kv) channels in pancreatic beta-cells play a key role in glucose-dependent insulin secretion. KMUP-1, a xanthine derivative, has been demonstrated to modulate Kv channel activity in smooth muscles; however, the role of KMUP-1 in glucotoxicity-activated Kv channels in pancreatic beta-cells remains unclear. In this study we examined the mechanisms by which KMUP-1 could inhibit high glucose (25 mM) activated Kv currents (IKv) in pancreatic beta-cells. Pancreatic beta-cells were isolated from Wistar rats and IKv was monitored by perforated patch-clamp recording. The peak IKv in high glucose-treated beta-cells was ~1.4-fold greater than for normal glucose (5.6 mM). KMUP-1 (1, 10, 30 MUM) prevented high glucose-stimulated IKv in a concentration-dependent manner. Reduction of high glucose-activated IKv was also found for protein kinase A (PKA) activator 8-Br-cAMP (100 MUM). Additionally, KMUP-1 (30 MUM) current inhibition was reversed by the PKA inhibitor H-89 (1 MUM). Otherwise, pretreatment with the PKC activator or inhibitor had no effect on IKv in high glucose exposure. In conclusion, glucotoxicity-diminished insulin secretion was due to IKv activation. KMUP-1 attenuated high glucose-stimulated IKv via the PKA but not the PKC signaling pathway. This finding provides evidence that KMUP-1 might be a promising agent for treating hyperglycemia-induced insulin resistance. PMID- 29183754 TI - Nitroxide Tempol down-regulates kinase activities associated with NADPH oxidase function in phagocytic cells and potentially decreases their fungicidal response. AB - AIMS: The identification of novel targets to control inflammation in humans is probably the primary challenge that impairs the development of new anti inflammatory drugs. Therefore, the modulation of intracellular signaling pathways in phagocytes may be an interesting means of achieving this goal. However, this change to signaling can compromise the host's susceptibility to invading pathogens. We investigated whether the antioxidant nitroxide Tempol regulates the activity of kinases associated with the production of oxidants in neutrophils, which affects the fungicidal capability of these cells. MAIN METHODS: The effects of Tempol on PMA- or fMLP-activated neutrophils were examined by oxygen consumption as an index of the oxidative burst, a release of extracellular and total Reactive Oxygen Species (ROS) by chemiluminescence, kinase activities through analysis of ATP consumption during enzyme activities and the dot blot immunoassay and, finally, by neutrophil capacity of killing Candida albicans. KEY FINDINGS: Tempol significantly inhibited the neutrophil oxidative burst in a concentration-dependent manner and decreased oxygen consumption (IC50 = 45 MUM) and extracellular/total ROS formation with an increase on the lag period response. In addition, Tempol inhibited neutrophil kinase activities (i.e., a decrease in protein phosphorylation) elicited through different biochemical pathways and consequently impaired the fungicidal activity of these cells. SIGNIFICANCE: Although Tempol has potential anti-inflammatory activity that acts on different intracellular pathways (such as those involving kinases), researchers should be cautious, since this nitroxide down-regulated oxidants production and the fungicidal response of neutrophils. PMID- 29183755 TI - Structural determination, distribution, and physiological actions of ghrelin in the guinea pig. AB - We identified guinea pig ghrelin (gp-ghrelin), and examined its distribution and physiological actions in the guinea-pig. Gp-ghrelin is a 28-amino acid peptide (GASFR SPEHH SAQQR KESRK LPAKI QPR); seven amino acids are different from that of rat ghrelin at positions 2, 5, 10, 11, 19, 21, and 25, which include the conserved region known in mammals. The third serine residue is mainly modified by n-decanoyl acid. Both gp-ghrelin and rat ghrelin increased intracellular Ca2+ concentration of HEK293 cells expressing guinea pig growth hormone secretagogue receptor 1a (GHS-R1a), and the affinity of gp-ghrelin was slightly higher than that of rat ghrelin. In addition, gp-ghrelin was also effective in CHO cells expressing rat GHS-R1a with similar affinity to that of rat ghrelin. Gp-ghrelin mRNA was predominantly expressed in the stomach, whereas the expression levels in other organs was low. High levels of GHS-R1a mRNA expression were observed in the pituitary, medulla oblongata, and kidney, while medium levels were noted in the thalamus, pons, olfactory bulb, and heart. Immunohistochemistry identified gp ghrelin-immunopositive cells in the gastric mucosa and pancreas. Intraperitoneal injection of gp-ghrelin increased food intake in the guinea pig. Gp-ghrelin did not cause any mechanical responses in isolated gastrointestinal smooth muscles in vitro, similar to rat ghrelin. In conclusion, the N-terminal structures that are conserved in mammals were different in gp-ghrelin. Moreover, the functional characteristics of gp-ghrelin, other than its distribution, were dissimilar from those in other Rodentia. PMID- 29183756 TI - Activiated galanin receptor 2 attenuates insulin resistance in skeletal muscle of obese mice. AB - The results of our and other's studies showed that activation of galanin receptor 1 could mitigate insulin resistance via promoting glucose transporter 4 (GLUT4) expression and translocation in the skeletal muscle of rats. But no literature are available regarding the effect of galanin receptor 2 (GALR2) on insulin resistance in skeletal muscle of type 2 diabetes. Herein, in this study we intended to survey the effect of GALR2 and its signal mechanisms in the mice with high fat diet-induced obese. The mice were intraperitoneally injected with vehicle, GALR2 agonist M1145 and antagonist M871 respectively once a day for continuous 21 days. The skeletal muscles were processed for determination of glucose uptake, and GLUT4 mRNA and protein expression levels. The PGC-1alpha, AKT, p38MAPK, AS160, pAKT, pP38MAPK and pAS160 expression levels were quantitatively assessed too. We found that pharmacological activation of GALR2 enhanced energy expenditure, and increased GLUT4 expression and translocation in skeletal muscle of mice during high-fat diet regimens. Activation of GALR2 alleviated insulin resistance through P38MAPK/PGC-1alpha/GLUT4 and AKT/AS160/GLUT4 pathway in the skeletal muscle of mice. Overall, these results identify that GALR2 is a regulator of insulin resistance and activation of GALR2 represents a promising strategy against obesity-induced insulin resistance. PMID- 29183757 TI - Virulence and resistance on various pathogens mediated by mobile genetic integrons via high flux assays. AB - BACKGROUND: Recognized as a resistance mechanism responsible for the emergence and prevalence of antimicrobial resistance, integron is widely distributed and spread among clinical microorganisms and play a key role in the dissemination of such antimicrobial resistance, which may eventually contribute to the unleashing of "Super Bugs" In this study, detection assays based on loop-mediated isothermal amplification (LAMP) methodologies targeting on class 1 to class 3 integrase genes was developed and evaluated. METHODS: LAMP methodology was employed to develop novel detection assays on class 1, 2 and 3 integrons. Firstly, this protocol was specifically designed to detect such integrons by targeting integrase genes intI1, intI2 and intI3. Development, evaluation and optimization of such LAMP assays was studied, including the reaction temperature, volumn, time, sensitivity and specificity of both primers and targets. A total of 1082 strains, including 397 integron positive and 685 integron negative microorganisms, were included for the application verification of the established LAMP assays. RESULTS: The indispensability of each primer was confirmed, and the optimal amplification was obtained under 63 degrees C for 45 min, with 25 MUl reaction found to be the most cost-efficient volume. As application was concerned, all of the 397 integron-positive isolates yielded positive amplicons and other 685 integron-negative bacteria were negative for the integron-LAMP assays, revealing totaling 100% detection rate and specificity. CONCLUSIONS: The established integron-LAMP assays was demonstrated to be a valid and rapid detection method for integrons screening, which may aid in both the laboratory and clinical integron screening for microorganisms. PMID- 29183758 TI - Evaluation of intrinsic and acquired immune cells infiltration in kidney and spleen of the mice infected with systemic candidiasis and treated with chloroform fraction of Zataria Multiflora Boiss. AB - BACKGROUND AND AIMS: Despite the use of antifungal drugs, the visceral candidiasis is associated with a high mortality rate. The aims of this study were an evaluation of intrinsic and acquired immune cells infiltration in kidney and spleen of the mice infected with systemic candidiasis and treated with chloroform fraction of Zataria Multiflora Boiss. MATERIALS AND METHODS: Candida albicans (C. albicans) ATCC10231 clinical standard strain was isolated. C. albicans LD50 was determined. The laboratory animal (BALB/C mouse) infection with the visceral candidiasis was performed. The kidney and spleen tissues were stained with PAS and prepared for confirmation under the microscope. The Zataria Multiflora Boiss (Shiraz thyme) was prepared and the effects on the infected group were assessed. The kidney and spleen mononuclear cells (MNCs) were prepared and the flow cytometry technique was performed for the assessment of Th1, Th17, and Treg cells. RESULTS: The LD50 and LD totals were 1.5 * 108 and 2 * 108 Yeast/0.1 ml, respectively. In mice which had a drug intervention, including chloroform fraction of Zataria Multiflora Boiss, thymol, carvacrol or fluconazole, fungal purification was greater in the spleen than in the kidney. Among those mice without medication intervention, fungal clearance was higher in the kidney. The highest percentage of TH1 cells was in group 1 and then group 4 and in groups 2 and 3 respectively. Moreover, there was a significant difference between groups 4 and 5 and also 6 and 7. The percentage of TH1 cells in the spleen MNCs was higher than that of the kidney cells, which is the difference between the groups except for group 7. The percentage of TH17 cells in the kidney and spleen of all drug receiving groups exhibited a significant increase compared to groups 6 and 7. The percentage of Treg cells in the kidney and the spleen only in the extract receiving group had a significant decrease compared to the non-drug receiving group and the other groups receiving group depicted no significant difference in the percentage of Treg cells. CONCLUSION: In addition to the direct effect on the fungus proven in vitro, the extract exhibits immunosuppressive effects, and thus can degrade the fungus through this way. The results demonstrated that the fraction of Zataria Multiflora Boiss can be considered as a powerful alternative to C. albicans therapy along with other therapies. PMID- 29183759 TI - Phosphodiesterase 4B plays a role in benzophenone-3-induced phototoxicity in normal human keratinocytes. AB - Benzophenone-3 (BP-3), which is extensively used in organic sunscreen, has phototoxic potential in human skin. Phosphodiesterase 4B (PDE4B) has a well established role in inflammatory responses in immune cells. Currently, it is unknown if PDE4B is associated with BP-3-induced phototoxicity in normal human keratinocytes (NHKs). We found that BP-3 significantly increased PDE4B expression in ultraviolet B (UVB)-irradiated NHKs. Notably, BP-8, a sunscreen agent that shares the 2-hydroxy-4-methoxyphenyl methanone moiety with BP-3, also upregulated PDE4B expression in NHKs. Upon UVB irradiation, BP-3 upregulated the expression of pro-inflammatory factors, such as prostaglandin endoperoxide synthase 2, tumor necrosis factor alpha, interleukin 8, and S100A7, and downregulated the level of cornified envelope associated proteins, which are important in the development of the epidermal permeability barrier. The additive effects of UVB-activated BP-3 on the expression of both pro-inflammatory mediators and cornified envelope associated proteins were antagonized by treatment with the PDE4 inhibitor rolipram. The BP-3 and UVB co-stimulation-induced PDE4B upregulation and its association with the upregulation of pro-inflammatory mediators and the downregulation of epidermal differentiation markers were confirmed in a reconstituted three dimensional human epidermis model. Therefore, PDE4B has a role in the mechanism of BP-3-induced phototoxicity. PMID- 29183760 TI - Th17 pathway in recent-onset autoimmune diabetes. AB - AIMS: Evaluate the participation of IL-17 pathway in T1D pathogenesis. T helper 17 cells are potent, highly inflammatory cells that produce interleukin 17A (IL 17A), considered a mediator of various immune disorders. However, their role in Type 1 diabetes (T1D) pathogenesis in humans is not totally elucidated. METHODS: The expression of IL-17 Receptor A (IL-17RA) in peripheral T lymphocytes and IL 17A serum levels in recent-onset patients with T1D were compared with healthy controls. IL-17A gene variants were evaluated in a greater cohort. RESULTS: Patients with recent-onset T1D (less than 6 months of diagnosis) exhibited lower expression of IL-17RA in CD3+ T (% of cells = 31.3% * 43.6%; p = .041) and CD4+ T cells (11.1% * 25.2%; p = .0019) and lower number of IL-17RA in CD4+ T cells (MFI = 1.16 * 4.56; p = .03) than controls. IL-17RA expression in CD8+ T cells and IL 17A serum levels were similar in both groups. The coding regions and boundary intron sequences of IL17A were sequenced. Seventeen allelic variants, including three novel variants in exon 3 (3'UTR n) were identified, but no one was associated with T1D susceptibility, as well as the resulting haplotypes and diplotypes. The expression of IL-17RA was not correlated with metabolic variables (glucose and HbA1c levels) or pancreatic autoantibodies titers. CONCLUSIONS: The lower expression of IL-17RA in CD3+ and CD4+ T cells suggests a reduced effect of IL-17A in immune response of recent-onset T1D patients, at least at peripheral tissues. IL-17A allelic variants were not related with T1D susceptibility.

AB - Fifty-five core marine sediments from three locations at South China Sea and one location each at Sulu Sea and Sulawesi Sea of coastal East Malaysia were analyzed for heavy metals by instrumental neutron activation analysis and inductively coupled plasma mass spectroscopy. The enrichment factor and the modified degree of contamination were used to calculate the anthropogenic and pollution status of the elements in the samples. The enrichment factor of As, Cd, Cr, Cu, Ni, Pb, and Zn varied from 0.42-4.26, 0.50-2.34, 0.31-0.82, 0.20-0.61, 0.91-1.92, 0.23-1.52, and 0.90-1.28, respectively, with the modified degree of contamination values below 0.6. Comparative data showed that coastal East Malaysia has low levels of contamination. PMID- 29183763 TI - A rare case of esophageal lymphoepithelial carcinoma without Epstein-Barr virus infection. PMID- 29183764 TI - Clinical outcome of portal vein thrombosis in patients with digestive cancers: A large AGEO multicenter study. AB - INTRODUCTION: Management of portal vein thrombosis (PVT) in cancer patients remains discussed. AIMS: The objective of this multicenter retrospective study was to investigate the management and outcome of PVT in patients with digestive cancers other than hepatocellular carcinoma (HCC). METHOD: Main inclusion criteria were trunk or branch PVT in patients with locally advanced or metastatic digestive cancers. Predictive factors of bleeding and overall survival (OS) were evaluated in univariate and multivariate analysis. RESULTS: Between 2012 and 2016, 118 patients with PVT and digestive cancers were identified. The majority had a pancreatic cancer (50%). Sixty-six percent of patients had trunk PVT location. Endoscopic screening of portal hypertension was performed in only 7 patients (1%) and 5 had esophageal varices. Gastrointestinal bleeding occurred in 22 patients (19%) and 12 patient deaths (17%) were related to a gastrointestinal hemorrhage. Metastatic disease (HR=2.83 [95%CI 1.47-5.43], p<0.01) and gastrointestinal hemorrhage (HR=1.68 [95%CI 1.01-2.78], p=0.04) were associated with OS in multivariate analysis. Only trunk PVT location was significantly associated with gastrointestinal hemorrhage in multivariate analysis (HR=5.56 [95%CI 1.18-26.32], p=0.03). CONCLUSION: A high rate of variceal bleeding leading to death was found in this cohort. Endoscopic screening and the efficacy of prophylactic treatment of variceal bleeding remain to be evaluated in a prospective study.

AB - Stressful events during gestation can have sex-specific effects on brain and behaviour, and may contribute to some of the differences observed in adult stress responding and psychopathology. We investigated the impact of a novel repeated prenatal psychological stress (prenatal predator exposure - PPS) during the last week of gestation in rats on offspring behaviours related to social interaction (play behaviour), open field test (OFT), forced swim test (FST) and sucrose preference test (SP) during the juvenile period and in adulthood. We further examined the role of postnatal environmental, using an enhanced housing condition (EHC), to prevent/rescue any changes. Some effects on anxiety, anhedonia, and stress-related coping behaviours (e.g., OFT, SP and OFT) did not emerge until adulthood. PPS increased OFT anxiety behaviours in adult males, and some OFT and SP behaviours in adult females. Contrary to this, EHC had few independent effects; most were apparent only when combined with PPS. In keeping with age group differences, juvenile behaviours did not necessarily predict the same adult behaviours although juvenile OFT rearing and freezing, and juvenile FST immobility did predict adult FST immobility and sucrose preference, suggesting that some aspects of depressive behaviours may emerge early and predict adult vulnerability or coping behaviours. Together, these results suggest an important, though complex, role for early life psychological stressors and early life behaviours in creating an adult vulnerability to anxiety or depressive disorders and that environmental factors further modulate the effects of the prenatal stressors. PMID- 29183766 TI - Ketogenic diet using a Japanese ketogenic milk for patients with epilepsy: A multi-institutional study. AB - BACKGROUND: In Japan, Meiji 817-B (M817-B), a powdered ketogenic milk, has been available since the ketogenic diet was introduced to infants and tube-fed children with medication-resistant epilepsy in the 1980s. METHODS: We retrospectively evaluated the efficacy, tolerability, and side effects of the ketogenic diet using M817-B as the main source of daily food intake for patients with epilepsy by sending questionnaires to the members of a subcommittee of the Japan Epilepsy Society that focuses on the proper use of M817-B. RESULTS: A total of 42 patients were enrolled. Age at the initiation of the diet therapy ranged from 3 to 244 months (median, 32.5 months). Thirty-four patients were fed via tube, and the remaining 8 were fed orally. About 93% of patients were able to continue the diet for 1 month, 74% for 3 months, and 64% for 6 months. The median period of continuation was 16 months. One patient was able to continue as long as 7 years. The ketogenic ratio was maintained at about 3.0. The seizure-free rate and responder (>50% seizure reduction) rate were about 10% and 30-40%, respectively during the 12 months on the diet. Mean serum beta-hydroxybutyrate increased to almost 4 mM at 1 month and was maintained during the diet period. Side effects, which required discontinuation of the diet therapy, occurred in 11 of 42 patients and included hypertonia, weight loss, vomiting, hypoglycemia, metabolic acidosis, and hypokalemia. CONCLUSION: M817-B could be used long-term with demonstrated efficacy in seizure reduction, although there are some side effects that may require cessation of the diet therapy. PMID- 29183767 TI - Diabetes induces mitochondrial dysfunction and alters cholesterol homeostasis and neurosteroidogenesis in the rat cerebral cortex. AB - The nervous system synthesizes and metabolizes steroids (i.e., neurosteroidogenesis). Recent observations indicate that neurosteroidogenesis is affected by different nervous pathologies. Among these, long-term type 1 diabetes, together with other functional and biochemical changes, has been shown to alter neuroactive steroid levels in the nervous system. Using an experimental model of type 1 diabetes (i.e., streptozotocin injection) we here show that the levels of these molecules are already decreased in the rat cerebral cortex after one month of the initiation of the pathology. Moreover, decreased levels of free cholesterol, together with alterations in the expression of molecules involved in cholesterol biosynthesis, bioavailability, trafficking and metabolism were detected in the rat cerebral cortex after one month of diabetes. Furthermore, mitochondrial functionality was also affected in the cerebral cortex and consequently may also contribute to the decrease in neuroactive steroid levels. Altogether, these results indicate that neurosteroidogenesis is an early target for the effect of type 1 diabetes in the cerebral cortex. PMID- 29183768 TI - Cardiovascular and renal interactions between cyclosporine and NSAIDs: Underlying mechanisms and clinical relevance. AB - Cyclosporine, the prototype calcineurin inhibitor, transformed immunosuppressant regimens and practices post-organ transplantation. Therapeutic uses of cyclosporine branched out to include management of different autoimmune disorders. However, multiple additional effects posed significant clinical challenges in face of the prolonged nature of cyclosporine use. Significantly, cyclosporine produced nephrotoxic, cardiotoxic and neurotoxic effects in addition to alteration of hemodynamic function. These adverse effects are shared with other drug groups further complicating the therapeutic situation to include potential exacerbation in case of drug interactions. The potential for detrimental outcomes increases with commonly used drugs such as non-steroidal anti-inflammatory drugs also notorious for their deleterious renal and cardiovascular effects. Herein, we review the available experimental and clinical evidence describing the mechanisms and the outcomes of interactions between the two drug classes. Special attention is given to the divergent toxic effects of co administration of cyclosporine with selective vs. non-selective cyclooxygenase inhibiting non-steroidal drugs. PMID- 29183769 TI - TPL2 kinase action and control of inflammation. AB - Tumor progression locus 2 (TPL2, also known as COT or MAP3K8) is a mitogen activated protein kinase kinase (MAP3K) activated downstream of TNFalphaR, IL1R, TLR, CD40, IL17R, and some GPCRs. TPL2 regulates the MEK1/2 and ERK1/2 pathways to regulate a cascade of inflammatory responses. In parallel to this, TPL2 also activates p38alpha and p38delta to drive the production of various inflammatory mediators in neutrophils. We discuss the implications of this finding in the context of various inflammatory diseases. PMID- 29183770 TI - Nutraceuticals: An emerging therapeutic approach against the pathogenesis of Alzheimer's disease. AB - Alzheimer's disease (AD) is regarded as a progressive and devastating neurodegenerative disorder. In aged individuals, it is the most prevalent cause of dementia and is characterized by gradual loss of cognitive functions. In the last decade, numerous research works were undertaken to investigate the pathogenesis of AD. Although the etiology of AD is still not clear, several histopathological studies confirm prominent changes in the AD affected brains. The major changes include the formation of senile plaques and neurofibrillary tangles primarily owing to the deposition of amyloid beta plaques (Abeta) and hyper-phosphorylation of tau protein. Disruption of the redox homeostasis in the brain is a major triggering factor for the development of such pathophysiological conditions. Chemical formulations usually act by inhibiting activities of the enzymes responsible for the development of AD. But with time, these pharmacotherapies develop many side effects including toxicity in different organs. Recent researches are henceforth focused on the identification of novel therapeutic molecules from the nature's basket. This review aims to emphasize the therapeutic effects and regulation of molecular targets of different natural products such as curcumin, resveratrol, genistein and others. These prophylactic multipotent natural compounds have the potency to interfere with the formation as well as deposition of the Abeta peptides. These natural compounds have also been found in modulating different intracellular signalling molecules and enzymes including beta-secretase and gamma-secretase. This review article is expected to be helpful in understanding the recent progress in natural product research as a therapeutic approach in amelioration and/or delaying the detrimental effects of AD. PMID- 29183771 TI - Comparative study of Candida spp. isolates: Identification and echinocandin susceptibility in isolates obtained from blood cultures in 15 hospitals in Medellin, Colombia. AB - OBJECTIVES: Invasive candidiasis has a high impact on morbidity and mortality in hospitalised patients. Accurate and timely methods for identification of Candida spp. and determination of echinocandin susceptibility have become a priority for clinical microbiology laboratories. METHODS: This study was performed to compare matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF/MS) identification with sequencing of the D1/D2 region of the rRNA gene complex 28 subunit in 147 Candida spp. isolates obtained from patients with candidaemia. Antimicrobial susceptibility testing was performed by broth microdilution (BMD) and Etest. Sequencing of the FKS1 and FKS2 genes was performed. RESULTS: The most common species isolated were Candida albicans (40.8%), followed by Candida parapsilosis (23.1%) and Candida tropicalis (17.0%). Overall agreement between the results of identification by MALDI-TOF/MS and molecular identification was 99.3%. Anidulafungin and caspofungin susceptibility by the BMD method was 98.0% and 88.4%, respectively. Susceptibility to anidulafungin and caspofungin by Etest was 93.9% and 98.6%, respectively. Categorical agreement between Etest and BMD was 91.8% for anidulafungin and 89.8% for caspofungin, with lower agreements in C. parapsilosis for anidulafungin (76.5%) and C. glabrata for caspofungin (40.0%). No mutations related to resistance were found in the FKS genes, although 54 isolates presented synonymous polymorphisms in the hotspots sequenced. CONCLUSIONS: MALDI-TOF/MS is a good alternative for routine identification of Candida spp. isolates. DNA sequencing of the FKS genes suggested that the isolates analysed were susceptible to echinocandins; alternatively, unknown resistance mechanisms or limitations related to antifungal susceptibility tests may explain the resistance found in a few isolates.

AB - BACKGROUND: Accelerated subcutaneous immunotherapy (SCIT) schedules represent an alternative to conventional SCIT, providing immunotherapy benefits in a shorter period of time. The objectives of this systematic review were to assess clinical and immunological efficacy as well as safety of accelerated SCIT build-up schedules for the treatment of respiratory allergy in pediatric patients. METHODS: Studies were located by searching PubMed, using "immunotherapy" and "desensitization" as keywords. The selection of studies, published from January 1st, 2006, to December 31th, 2015, was performed in two stages: screening of titles and abstracts, and assessment of the full papers identified as relevant, considering the inclusion criteria. Data were extracted in a standardized way and synthesized qualitatively to assess efficacy and safety of accelerated schedules in respiratory allergy. RESULTS: Eleven trials were included: two evaluated rush SCIT and nine assessed cluster SCIT. This review demonstrated that rush and cluster schedules are clinically and immunological efficacious, with faster effect than conventional schedules. No relevant difference with respect to clinical outcomes was noticed between subgroups (pediatric, adult and mixed populations). Regarding safety, most local adverse reactions were mild and there were neither life-threatening systemic reactions nor fatal events. No relevant differences in the incidence and severity of either local or systemic reactions between the accelerated schedule group and control group were registered. CONCLUSIONS: Accelerated SCIT build-up schedules are effective in the treatment of respiratory allergy in pediatric patients, representing a safe alternative to the conventional schedules with the advantage of achieving clinical effectiveness sooner. PMID- 29183775 TI - Novel effects of phytoestrogenic soy isoflavones on serum calcium and chloride in premenopausal women: A 2-year double-blind, randomized, placebo-controlled study. AB - BACKGROUND: Soy phytoestrogens are potential alternatives to postmenopausal hormone replacement therapy (HRT). Adverse effects of HRT such as myocardial infarction, stroke, and pulmonary embolism are mediated by calcium-induced signaling. OBJECTIVE: To determine whether soy isoflavones affect serum calcium in healthy female subjects. DESIGN: In a double-blind trial, 197 premenopausal women were randomly assigned to either isoflavone (N = 99) or placebo pills (N = 98) 5 days per week for up to 2 years, plus prenatal vitamins. Isoflavone pills contained 60 mg genistein, 60 mg daidzein and 16.6 mg glycitein (expressed as aglycone equivalents). All pills contained 15 mg riboflavin as an adherence marker. Blood chemistries and urinary daidzein, genistein and riboflavin were measured multiple times during the luteal phase before and during treatment. RESULTS: Analysis of the adherent population (N = 83 per group), revealed significantly strong associations between urinary levels of isoflavones and serum concentrations of calcium (regression coefficients 0.082 for daidzein and 0.229 for genistein, all P < 0.01) and chloride (regression coefficient, -1.537 for genistein, P < 0.0001), mediated in part by albumin. The effects amounted to mean changes of +0.24 mg/dL for calcium and -1.45 mEq/L for chloride, with each visit for subjects excreting the most vs. the least amounts of isoflavones. These associations were not evident in the intention-to-treat analysis (N = 197) that did not assess expected variations in isoflavone levels within and between subjects from metabolism and adherence. CONCLUSIONS: These novel and strong effects of soy isoflavones on calcium homeostasis have important implications for long term effects of these natural substances on cardiovascular diseases. PMID- 29183776 TI - Assessment of microstructural signal compartments across the corpus callosum using multi-echo gradient recalled echo at 7 T. AB - Quantitative assessment of tissue microstructure is important in studying human brain diseases and disorders in which white matter is implicated, as it has been linked to demyelination, re-myelination, and axonal damage in clinical conditions. Ultra-high field magnetic resonance imaging data obtained using a multi-echo gradient echo sequence has been shown to contain information on myelin, axonal and extracellular compartments in white matter. In this study, we aimed to assess the sensitivity of a three-compartment model to estimate the variation of corresponding compartment parameters (water fraction, relaxation time and frequency shift) of the corpus callosum sub-regions, which are known to have different tissue structure. Additionally, we computed the g-ratio using myelin and axonal water fractions and performed a voxel-by-voxel analysis in the corpus callosum. Based on data acquired for ten participants, we show that the myelin compartment water fraction and T2* is consistent across the corpus callosum sub-regions, whilst myelin frequency shift varies. The results show that the variation in water fraction, T2* and frequency shift for the myelin signal compartment across the corpus callosum is smaller than for the axonal and extracellular signal compartments. The computed g-ratio was comparable to previously published studies in the corpus callosum. Our study suggests that a multi-echo GRE approach in vivo combined with a complex three-compartment model is sensitive to microstructural parameter variations across the human corpus callosum. PMID- 29183777 TI - Sensory and semantic activations evoked by action attributes of manipulable objects: Evidence from ERPs. AB - "Two route" theories of object-related action processing posit different temporal activation profiles of grasp-to-move actions (rapidly evoked based on object structure) versus skilled use actions (more slowly activated based on semantic knowledge). We capitalized on the exquisite temporal resolution and multidimensionality of Event-Related Potentials (ERPs) to directly test this hypothesis. Participants viewed manipulable objects (e.g., calculator) preceded by objects sharing either "grasp", "use", or no action attributes (e.g., bar of soap, keyboard, earring, respectively), as well as by action-unrelated but taxonomically-related objects (e.g., abacus); participants judged whether the two objects were related. The results showed more positive responses to "grasp-to move" primed objects than "skilled use" primed objects or unprimed objects starting in the P1 (0-150 ms) time window and continuing onto the subsequent N1 and P2 components (150-300 ms), suggesting that only "grasp-to-move", but not "skilled use", actions may facilitate visual attention to object attributes. Furthermore, reliably reduced N400s (300-500 ms), an index of semantic processing, were observed to taxonomically primed and "skilled use" primed objects relative to unprimed objects, suggesting that "skilled use" action attributes are a component of distributed, multimodal semantic representations of objects. Together, our findings provide evidence supporting two-route theories by demonstrating that "grasp-to-move" and "skilled use" actions impact different aspects of object processing and highlight the relationship of "skilled use" information to other aspects of semantic memory. PMID- 29183778 TI - Current WHO guidelines and the critical role of immunohistochemical markers in the subclassification of non-small cell lung carcinoma (NSCLC): Moving from targeted therapy to immunotherapy. AB - Recent large scale genomic studies from the Clinical Lung Cancer Genome Project have identified different driver gene mutations in the subtypes of non-small cell lung carcinoma (NSCLC). These findings not only lead to remarkable progress in targeted therapies for lung cancer patients, but also provide fundamental knowledge for the subclassification of NSCLC. More recently, the advancement and clinical application of immunotherapy have reinforced the need for the accurate subclassification of NSCLC. In 2015, the World Health Organization (WHO) and the International Association for the Study of Lung Cancer (IASLC) updated their guidelines for the subclassification of lung cancers. These guidelines emphasize: (1) the subclassification of NSCLC, (2) the critical role of molecular characterization of tumors for targeted therapy, (3) the unique terminology for subclassifying NSCLC using small biopsy specimens, and (4) the utility of IHC biomarkers in the accurate diagnosis and subclassification of lung cancer. The guidelines have significant prognostic impact on oncologic practice and patient care. In this review, we summarize the current WHO guidelines for the classification of lung cancer, discuss advancements of targeted therapy and immunotherapy, and address the utility and limitation of immunomarkers in the subclassification of NSCLC, as well as the prospective future of the field. PMID- 29183780 TI - Effects of regular aerobic exercise on visual perceptual learning. AB - This study investigated the influence of five days of moderate intensity aerobic exercise on the acquisition and consolidation of visual perceptual learning using a motion direction discrimination (MDD) task. The timing of exercise relative to learning was manipulated by administering exercise either before or after perceptual training. Within a matched-subjects design, twenty-seven healthy participants (n = 9 per group) completed five consecutive days of perceptual training on a MDD task under one of three interventions: no exercise, exercise before the MDD task, or exercise after the MDD task. MDD task accuracy improved in all groups over the five-day period, but there was a trend for impaired learning when exercise was performed before visual perceptual training. MDD task accuracy (mean +/- SD) increased in exercise before by 4.5 +/- 6.5%; exercise after by 11.8 +/- 6.4%; and no exercise by 11.3 +/- 7.2%. All intervention groups displayed similar MDD threshold reductions for the trained and untrained motion axes after training. These findings suggest that moderate daily exercise does not enhance the rate of visual perceptual learning for an MDD task or the transfer of learning to an untrained motion axis. Furthermore, exercise performed immediately prior to a visual perceptual learning task may impair learning. Further research with larger groups is required in order to better understand these effects. PMID- 29183779 TI - Attention modulates trans-saccadic integration. AB - With every saccade, humans must reconcile the low resolution peripheral information available before a saccade, with the high resolution foveal information acquired after the saccade. While research has shown that we are able to integrate peripheral and foveal vision in a near-optimal manner, it is still unclear which mechanisms may underpin this important perceptual process. One potential mechanism that may moderate this integration process is visual attention. Pre-saccadic attention is a well documented phenomenon, whereby visual attention shifts to the location of an upcoming saccade before the saccade is executed. While it plays an important role in other peri-saccadic processes such as predictive remapping, the role of attention in the integration process is as yet unknown. This study aimed to determine whether the presentation of an attentional distractor during a saccade impaired trans-saccadic integration, and to measure the time-course of this impairment. Results showed that presenting an attentional distractor impaired integration performance both before saccade onset, and during the saccade, in selected subjects who showed integration in the absence of a distractor. This suggests that visual attention may be a mechanism that facilitates trans-saccadic integration. PMID- 29183781 TI - Evolution of Sucrose Metabolism: The Dichotomy of Invertases and Beyond. AB - In higher plants, invertases hydrolyze sucrose (Suc), the major end product of photosynthesis, into glucose (Glc) and fructose (Fru), which are used as nutrients, energy sources, and signaling molecules for plant growth, yield formation, and stress responses. The invertase enzymes, named CWINs, VINs, and CINs, are located in the cell wall, vacuole, and cytosol, respectively. We hypothesize, based on their distinctive subcellular locations and physiological roles, that invertases may have undergone different modes during evolution with important functional implications. Here, we provide phylogenetic and functional genomic evidence that CINs are evolutionarily and functionally more stable compared with CWINs and VINs, possibly reflecting their roles in maintaining cytosolic sugar homeostasis for cellular function, and that CWINs have coevolved with the vasculature, likely as a functional component of phloem unloading. PMID- 29183782 TI - Impact of dolutegravir and efavirenz on immune recovery markers: results from a randomized clinical trial. AB - OBJECTIVES: CD4/CD8 ratio and CD4+ T-cell percentage (CD4%) predicts the risk of AIDS and non-AIDS events. Multiple T-cell marker recovery (MTMR) has been proposed as the most complete level of immune reconstitution. We quantified differences in the CD4/CD8 ratio, CD4% recovery and MTMR after starting HIV-1 treatment with dolutegravir/abacavir/lamivudine vs. efavirenz (EFV)/tenofovir (TDF)/emtricitabine (FTC). METHODS: Exploratory post hoc analysis of the SINGLE study, a randomized double-blind, clinical trial. Percentage differences and corresponding precision based on 95% confidence intervals, and p values were calculated for CD4/CD8 ratio normalization, CD4% normalization and the achievement of MTMR. Cox models taking into account competing risks were used to estimate sub-hazard ratios when comparing the times to normalization of the CD4/CD8 ratio and the CD4% by treatment arm. RESULTS: Data from 833 participants were analysed (414 in the dolutegravir/abacavir/lamivudine arm). There were no statistically significant differences in the proportion of patients who reached a CD4/CD8 ratio >=0.5 at weeks 48 and 96. However, at week 96, the proportion of patients with a CD4/CD8 ratio >=1 was higher in the EFV-TDF-FTC group (difference, 11.70; 95% confidence interval, 4.49-18.91; p 0.002). The decrease from baseline in CD8+ cell count was consistently greater in the EFV-TDF-FTC arm. Analysis of CD4+ percentages showed no significant differences during the study. The proportion of patients attaining a MTMR was higher in the EFV-TDF-FTC group, although the difference was only statistically significant at week 96 (p 0.001). CONCLUSIONS: EFV-TDF-FTC showed significantly greater increases in CD4/CD8 ratio >=1.0 or MTMR beyond treatment week 96. Additional studies are necessary to better understand the impact of these findings. PMID- 29183783 TI - Mesenchymal lineage cells and their importance in B lymphocyte niches. AB - Early B lymphopoiesis occurs in the bone marrow and is reliant on interactions with numerous cell types in the bone marrow microenvironment, particularly those of the mesenchymal lineage. Each cellular niche that supports the distinct stages of B lymphopoiesis is unique. Different cell types and signaling molecules are important for the progressive stages of B lymphocyte differentiation. Cells expressing CXCL12 and IL-7 have long been recognized as having essential roles in facilitating progression through stages of B lymphopoiesis. Recently, a number of other factors that extrinsically mediate B lymphopoiesis (positively or negatively) have been identified. In addition, the use of transgenic mouse models to delete specific genes in mesenchymal lineage cells has further contributed to our understanding of how B lymphopoiesis is regulated in the bone marrow. This review will cover the current understanding of B lymphocyte niches in the bone marrow and key extrinsic molecules and signaling pathways involved in these niches, with a focus on how mesenchymal lineage cells regulate B lymphopoiesis. PMID- 29183784 TI - Osteocalcin improves insulin resistance and inflammation in obese mice: Participation of white adipose tissue and bone. AB - AIMS/HYPOTHESIS: The discovery of osteocalcin, a protein synthetized by osteoblasts, as a hormone that has positive effects on insulin resistance, contributed to support the concept of bone as an endocrine organ. However, very little is known about the molecular pathways involved in osteocalcin improved insulin resistance. The present study aimed to investigate the mechanisms of action of osteocalcin on insulin resistance and inflammation in obese mice and 3T3-L1 adipocytes. METHODS AND RESULTS: Lean control, saline-treated obese and uncarboxylated osteocalcin (uOC)-treated obese mice were subjected to insulin tolerance test in vivo. Blood was collect for biochemical/metabolic profile analysis; and, skeletal muscle, white adipose tissue (WAT) and bone were collected for protein (Western blotting) and mRNA (RT-qPCR) analysis. uOC effects on insulin resistance and inflammation were also investigated in 3T3-L1 adipocytes challenged with tumor necrosis factor. Osteocalcin treatment improved in vivo insulin resistance in obese mice. In WAT, osteocalcin had positive effects such as (1) WAT weight reduction; (2) upregulation of glucose transporter (GLUT) 4 protein and its mRNA (Slc2a4); (3) improved insulin-induced AKT phosphorylation; (4) downregulation of several genes involved in inflammation and inflammassome transcriptional machinery, and (5) reduction of the density of macrophage in crown-like structures (histomorphometrical analysis). Notably, in 3T3-L1 adipocytes, osteocalcin restored Slc2a4/GLUT4 content and reduced the expression of inflammatory genes after TNF-a challenge; moreover, osteocalcin treatment increased AKT phosphorylation induced by insulin. Finally, it was observed that in bone, osteocalcin improves insulin resistance by increasing insulin-induced AKT phosphorylation and reducing the expression of genes involved in bone insulin resistance, resulting in increased secretion of uncarboxylated osteocalcin in circulation. CONCLUSION: We provided some mechanisms of action for osteocalcin in the amelioration of insulin resistance in obesity: in WAT, osteocalcin improves insulin resistance by decreasing inflammation, and increasing insulin signaling and the expression of Slc2a4/GLUT4; and, in bone, osteocalcin increases the secretion of uncarboxylated osteocalcin by improving insulin resistance. PMID- 29183785 TI - Ablation of Gsalpha signaling in osteoclast progenitor cells adversely affects skeletal bone maintenance. AB - Gsalpha, the alpha stimulatory subunit of heterotrimeric G proteins that activates downstream signaling through the adenylyl cyclase and cAMP/PKA pathway, plays an important role in bone development and remodeling. The role of Gsalpha in mesenchymal stem cell (MSC) differentiation to osteoblasts has been demonstrated in several mouse models of Gsalpha inactivation. Previously, using mice with heterozygous germline deletion of Gsalpha (Gnas+/p-), we identified a novel additional role for Gsalpha in bone remodeling, and showed the importance of Gnas in maintaining bone quality by regulating osteoclast differentiation and function. In this study, we show that postnatal deletion of Gsalpha (CreERT2;Gnasfl/fl) leads to reduction in trabecular bone quality parameters and increased trabecular osteoclast numbers. Furthermore, mice with deletion of Gsalpha specifically in cells of the macrophage/osteoclast lineage (LysM Cre;Gnasfl/fl) showed reduced trabecular bone quality and increased trabecular osteoclasts, but to a reduced extent compared to the CreERT2;Gnasfl/fl global knockout. This demonstrates that while Gsalpha has a cell autonomous role in osteclasts in regulating bone quality, Gsalpha expression in other cell types additionally contribute. In both of these mouse models, cortical bone was more subtly affected than trabecular bone. Our results support that Gsalpha is required postnatally to maintain trabecular bone quality and that Gsalpha function to maintain trabecular bone is regulated in part through a specific activity in osteoclasts. PMID- 29183786 TI - Characterization of Protein Methyltransferases Rkm1, Rkm4, Efm4, Efm7, Set5 and Hmt1 Reveals Extensive Post-Translational Modification. AB - Protein methylation is one of the major post-translational modifications (PTMs) in the cell. In Saccharomyces cerevisiae, over 20 protein methyltransferases (MTases) and their respective substrates have been identified. However, the way in which these MTases are modified and potentially subject to regulation remains poorly understood. Here, we investigated six overexpressed S. cerevisiae protein MTases (Rkm1, Rkm4, Efm4, Efm7, Set5 and Hmt1) to identify PTMs of potential functional relevance. We identified 48 PTM sites across the six MTases, including phosphorylation, acetylation and methylation. Forty-two sites are novel. We contextualized the PTM sites in structural models of the MTases and revealed that many fell in catalytic pockets or enzyme-substrate interfaces. These may regulate MTase activity. Finally, we compared PTMs on Hmt1 with those on its human homologs PRMT1, PRMT3, CARM1, PRMT6 and PRMT8. This revealed that several PTMs are conserved from yeast to human, whereas others are only found in Hmt1. The mass spectrometry proteomics data have been deposited to the ProteomeXchange Consortium via the PRIDE partner repository with the dataset identifier PXD006767. PMID- 29183787 TI - Mechanism of Peptide Binding and Cleavage by the Human Mitochondrial Peptidase Neurolysin. AB - Proteolysis plays an important role in mitochondrial biogenesis, from the processing of newly imported precursor proteins to the degradation of mitochondrial targeting peptides. Disruption of peptide degradation activity in yeast, plant and mammalian mitochondria is known to have deleterious consequences for organism physiology, highlighting the important role of mitochondrial peptidases. In the present work, we show that the human mitochondrial peptidase neurolysin (hNLN) can degrade mitochondrial presequence peptides as well as other fragments up to 19 amino acids long. The crystal structure of hNLNE475Q in complex with the products of neurotensin cleavage at 2.7A revealed a closed conformation with an internal cavity that restricts substrate length and highlighted the mechanism of enzyme opening/closing that is necessary for substrate binding and catalytic activity. Analysis of peptide degradation in vitro showed that hNLN cooperates with presequence protease (PreP or PITRM1) in the degradation of long targeting peptides and amyloid-beta peptide, Abeta1-40, associated with Alzheimer disease, particularly cleaving the hydrophobic fragment Abeta35-40. These findings suggest that a network of proteases may be required for complete degradation of peptides localized in mitochondria. PMID- 29183788 TI - Reduction of Nonspecificity Motifs in Synthetic Antibody Libraries. AB - Successful antibody development requires both functional binding and desirable biophysical characteristics. In the current study, we analyze the causes of one hurdle to clinical development, off-target reactivity, or nonspecificity. We used a high-throughput nonspecificity assay to isolate panels of nonspecific antibodies from two synthetic single-chain variable fragment libraries expressed on the surface of yeast, identifying both individual amino acids and motifs within the complementarity-determining regions which contribute to the phenotype. We find enrichment of glycine, valine, and arginine as both individual amino acids and as a part of motifs, and additionally enrichment of motifs containing tryptophan. Insertion of any of these motifs into the complementarity-determining region H3 of a "clean" antibody increased its nonspecificity, with greatest increases in antibodies containing Trp or Val motifs. We next applied these rules to the creation of a synthetic diversity library based on natural frameworks with significantly decreased incorporation of such motifs and demonstrated its ability to isolate binders to a wide panel of antigens. This work both provides a greater understanding of the drivers of nonspecificity and provides design rules to increase efficiency in the isolation of antibodies with drug-like properties. PMID- 29183789 TI - A magnetic resonance imaging study of early brain injury in a rat model of acute DFP intoxication. AB - Current treatments for seizures induced by organophosphates do not protect sufficiently against progressive neurodegeneration or delayed cognitive impairment. Developing more effective therapeutic approaches has been challenging because the pathogenesis of these delayed consequences is poorly defined. Using magnetic resonance imaging (MRI), we previously reported brain lesions that persist for months in a rat model of acute intoxication with the OP, diisopropylfluorophosphate (DFP). However, the early spatiotemporal progression of these lesions remains unknown. To address this data gap, we used in vivo MRI to longitudinally monitor brain lesions during the first 3 d following acute DFP intoxication. Adult male Sprague Dawley rats acutely intoxicated with DFP (4mg/kg, sc) were MR imaged at 6, 12, 18, 24, 48, 72h post-DFP, and their brains then taken for correlative histology to assess neurodegeneration using FluoroJade C (FJC) staining. Acute DFP intoxication elicited moderate-to-severe seizure activity. T2-weighted (T2w) anatomic imaging revealed prominent lesions within the thalamus, piriform cortex, cerebral cortex, hippocampus, corpus striatum, and substantia nigra that corresponded to neurodegeneration, evident as bands of FJC positive cells. Semi-quantitative assessment of lesion severity demonstrated significant regional variation in the onset and progression of injury, and suggested that lesion severity may be modulated by isoflurane anesthesia. These results imply that the timing of therapeutic intervention for attenuating brain injury following OP intoxication may be regionally dependent, and that longitudinal assessment of OP-induced damage by MRI may be a powerful tool for assessing therapeutic response.

AB - Chronic exposure to manganese (Mn) causes neurotoxicity, referred to as manganism, with common clinical features of parkinsonism. 17beta-estradiol (E2) and tamoxifen (TX), a selective estrogen receptor modulator (SERM), afford neuroprotection in several neurological disorders, including Parkinson's disease (PD). In the present study, we tested if E2 and TX attenuate Mn-induced neurotoxicity in mice, assessing motor deficit and dopaminergic neurodegeneration. We implanted E2 and TX pellets in the back of the neck of ovariectomized C57BL/6 mice two weeks prior to a single injection of Mn into the striatum. One week later, we assessed locomotor activity and molecular mechanisms by immunohistochemistry, real-time quantitative PCR, western blot and enzymatic biochemical analyses. The results showed that both E2 and TX attenuated Mn induced motor deficits and reversed the Mn-induced loss of dopaminergic neurons in the substantia nigra. At the molecular level, E2 and TX reversed the Mn induced decrease of (1) glutamate aspartate transporter (GLAST) and glutamate transporter 1 (GLT-1) mRNA and protein levels; (2) transforming growth factor alpha (TGF-alpha) and estrogen receptor-alpha (ER-alpha) protein levels; and (3) catalase (CAT) activity and glutathione (GSH) levels, and Mn-increased (1) malondialdehyde (MDA) levels and (2) the Bax/Bcl-2 ratio. These results indicate that E2 and TX afford protection against Mn-induced neurotoxicity by reversing Mn reduced GLT1/GLAST as well as Mn-induced oxidative stress. Our findings may offer estrogenic agents as potential candidates for the development of therapeutics to treat Mn-induced neurotoxicity. PMID- 29183791 TI - Transforming growth factor beta 1 related gene polymorphisms in gestational hypertension and preeclampsia: A case-control candidate gene association study. AB - OBJECTIVES: To investigate the association between transforming growth factor beta 1 related gene polymorphisms and the occurrence of pregnancy induced hypertension, including gestational hypertension and preeclampsia. STUDY DESIGN: This is a case control candidate gene association study. A total of 130 patients with preeclampsia, 67 with gestational hypertension, and 316 controls were recruited. Eleven candidate SNPs of were examined, including four TGFbeta1 SNPs (rs1800469, rs4803455, rs4803457, and rs8179181), one TGFbetaR1 SNP (rs10739778), four TGFbetaR2 SNPs (rs1346907, rs3087465, rs6550005, and rs877572), and two ENG SNPs (rs10121110 and rs11792480). MAIN OUTCOME MEASURES: Logistic regression was used to estimate the OR and the 95% CI under different genetic models. Chi-square test was used to determine whether haplotype frequency distributions differed between the case and control groups and logistic regression was used to estimate ORs. To explore the associations between SNPs and blood pressure, SBP/DBP in different genotype groups in healthy women were compared by Wilcoxon rank sum test. RESULTS: We did not find significant association between investigated SNPs and pregnancy induced hypertension. The C-T-A-G haplotype of four TGFbetaR2 SNPs (rs877572, rs1346907, rs3087465, and rs6550005) was significantly associated with preeclampsia (OR = 4.71, 95%CI: 1.944, 11.409) and gestational hypertension (OR = 3.157, 95%CI: 1.003, 9.938). The AA genotype of TGFbetaR1 rs10739778 was found to be associated with higher blood pressure in healthy women (p <= .008). CONCLUSIONS: Polymorphisms in TGFbetaR2 might participate in the pathologic process of pregnancy induced hypertension, and TGFbetaR1 rs10739778 was associated with blood pressure in our healthy participants. PMID- 29183792 TI - When two become one: Electrocortical correlates of the integration of multiple action consequences. AB - In a recent study we have demonstrated that the feedback-related negativity (FRN) reflects the integrated value of instantaneous and delayed decision consequences (Osinsky et al. 2017). In the present work, we extend this research by using a novel choice task in which instant and delayed consequence values of a single decision outcome can be manipulated independently of each other in a trial-wise manner. Fifty-nine healthy participants completed this task while EEG was recorded. Twenty-two of them returned one week later for a retesting, allowing for investigating temporal stability of individual FRN indices. Our results show that the FRN mainly reflects the additively integrated value of instant and delayed outcome consequences. Individual differences in the FRN sensitivity to the two consequence dimensions were specifically predictive for consequence driven adjustments in choice behavior and moderately stable over time. Altogether, our findings are inconsistent with the idea that the FRN reflects a simple binary distinction between favorable and unfavorable action outcomes. Rather, the FRN appears to mirror a fine-grained scaling of action outcomes, which results from stable personal reward preferences and which is used for adjusting choice behavior. Given that the FRN is generated in the anterior midcingulate cortex, our study adds to recent literature according to which this structure uses multiple information to learn complex action-outcome values. PMID- 29183793 TI - The electrocortical response to rewarding and aversive feedback: The reward positivity does not reflect salience in simple gambling tasks. AB - The Reward Positivity (RewP) is an event-related potential (ERP) potentiated to monetary gains and reduced to monetary losses. Recently, competing data suggest that more salient outcomes elicit a positivity relative to less salient outcomes, regardless of valence. However, all previous work testing the impact of salience on the RewP have examined expected versus unexpected outcomes. In the current study, participants completed the same gambling task twice in which feedback was equally probable: in one condition, feedback indicated monetary gain or loss-and in the other condition, feedback indicated either safety or punishment from subsequent electric shock. Traditional ERP and principal component analysis (PCA) derived measures confirmed that the RewP was more positive to feedback signaling monetary gain and safety from shock compared to feedback signaling monetary loss and punishment with shock. These results align with models in which the RewP indexes reward-related processes, including reward prediction error models. Potential explanations for salience-based effects on the RewP are discussed. PMID- 29183794 TI - Characterization of carp gonadotropins: Structure, annual profile, and carp and zebrafish pituitary topographic organization. AB - Two gonadotropins, follicle stimulating hormone (FSH) and luteinizing hormone (LH), are important players in the hypothalamic-pituitary-gonadal axis of vertebrates. In the present work, we describe the construction of recombinant (r) common carp (Cyprinus carpio; c) FSH (rcFSH) and LH (rcLH) using the Pichia pastoris system, the generation of specific antibodies against their respective beta subunits, and their use in the development and validation of specific ELISAs. We produced carp rLH and rFSH as single-chain polypeptides, wherein the GTH subunit alpha was joined with either cLHbeta or cFSHbeta mature protein coding sequences to form a fusion gene that encodes a yoked polypeptide, in which the GTH beta-subunit forms the N-terminal part and the alpha-subunit forms the C terminal part. Competitive ELISAs were developed, using primary antibodies against rcLHbeta or rcFSHbeta, respectively, and rcLHbetaalpha or rcFSHbetaalpha for the standard curves. The standard curves for cLH paralleled those of pituitary extracts of the homologous fish and also those of other cyprinids species like the black carp (Mylopharyngodon piceus), goldfish (Carassius auratus), silver carp (Hypophthalmichthys molitrix), and grass carp (Ctenopharyngodon idella). We used the specific antibodies raised against cFSH and cLH to study the specific localization of the different GTH cells in the pituitary of carp and its taxonomic relative species - the zebrafish. Both FSH and LH cells are localized in the center of the proximal pars distalis enveloping both sides of the neurohypophysis. LH cells form a continuous population throughout the PPD, while FSH cells are more loosely distributed throughout the same area and form small aggregations. Marked annual changes were encountered in gonadosomatic index (GSI), follicle diameter, mRNA levels and protein levels of FSH and LH. From September to November, all fish had low GSI, and the ovary contained previtellogenic follicles. From December, the GSI level increased and remained high until March, the follicular diameter reached its maximum in January, where the ovary contained large fully grown follicles. Thereafter, spawning occurred through March and April and ended in May, and GSI level and follicle diameter increased again; and the ovary contained mid-vitellogenic follicles. LH pituitary content and mRNA levels were low at pre- and early vitellogenesis, increasing gradually during this process to reach a peak of LH mRNA levels in mid vitellogenic ovary and a peak of LH content in fully grown ovarian follicles. However, no significant change occurred in FSH pituitary content and mRNA levels in vitellogenic fish and in fish during final maturation stages. A dramatic difference was found in the total content of each gonadotropin in the pituitary, with higher LH than FSH. Moreover, follicle diameter was positively and significantly correlated with LH pituitary content and its transcript levels - but not with the pituitary content or mRNA levels of FSH. Taken together, these results indicate that in carp, LH alone is sufficient to regulate both vitellogenesis and final oocyte maturation while FSH may have another, yet undefined role. PMID- 29183795 TI - From zebrafish to human: A comparative approach to elucidate the role of the thyroid hormone transporter MCT8 during brain development. AB - Monocarboxylate transporter 8 (MCT8) facilitates transmembrane transport of thyroid hormones (THs) ensuring their action on gene expression during vertebrate neurodevelopment. A loss of MCT8 in humans results in severe psychomotor deficits associated with the Allan-Herndon-Dudley Syndrome (AHDS). However, where and when exactly a lack of MCT8 causes the neurological manifestations remains unclear because of the varying expression pattern of MCT8 between specific brain regions and cells. Here, we elaborate on the animal models that have been generated to elucidate the mechanisms underlying MCT8-deficient brain development. The absence of a clear neurological phenotype in Mct8 knockout mice made it clear that a single species would not suffice. The evolutionary conservation of TH action on neurodevelopment as well as the components regulating TH signalling however offers the opportunity to answer different aspects of MCT8 function in brain development using different vertebrate species. Moreover, the plethora of tools for genome editing available today facilitates gene silencing in these animals as well. Studies in the recently generated mct8-deficient zebrafish and Mct8/Oatp1c1 double knockout mice have put forward the current paradigm of impaired TH uptake at the level of the blood-brain barrier during peri- and postnatal development as being the main pathophysiological mechanism of AHDS. RNAi vector-based, cell specific induction of MCT8 knockdown in the chicken embryo points to an additional function of MCT8 at the level of the neural progenitors during early brain development. Future studies including also additional in vivo models like Xenopus or in vitro approaches such as induced pluripotent stem cells will continue to help unravelling the exact role of MCT8 in developmental events. In the end, this multispecies approach will lead to a unifying thesis regarding the cellular and molecular mechanisms responsible for the neurological phenotype in AHDS patients. PMID- 29183796 TI - Heat shock protein 70 suppresses neuroinflammation induced by alpha-synuclein in astrocytes. AB - Neuroinflammation triggered by activation of glial cells plays an important role in the pathophysiology of several neurodegenerative diseases including Parkinson's disease (PD). Besides microglia, astrocytes are also critical in initiating and perpetuating inflammatory process associated with PD. Heat shock protein 70 (Hsp70) is originally described as intracellular chaperone, however, recent study revealed that it had anti-inflammatory effects as well. The present study is designed to investigate whether Hsp70 mediates neuroinflammation in astrocytes. By employing alpha-synuclein (alpha-Syn) (A53T) aggregates on primary cultured astrocytes of rats, we found that astrocytes were activated and neuroinflammatory response was triggered, as indicated by over-expression of glial fibrillary acidic protein (GFAP), cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS), increased production of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta). The data also showed that the neuroinflammatory response accompanied up-regulated Hsp70 expression. Moreover, over-expression of Hsp70 through transfection of Hsp70 cDNA plasmids could significantly reduce the production of TNF-alpha, IL-1beta, and the expression of GFAP, COX-2 as well as iNOS. While inhibition of Hsp70 by VER155008 exacerbated neuroinflammatory response in astrocytes challenged by alpha-Syn aggregates. Further mechanistic study indicated that c-Jun N-terminal kinase (JNK) and nuclear factor-kappaB (NF-kappaB) signalings were responsible for the neuroinflammation, which was also regulated by Hsp70. These findings demonstrated that Hsp70 was an important modulator in astrocytes induced inflammation, and up regulation of Hsp70 might be a potential regulating approach for neuroinflammation-related neurodegenerative diseases, such as PD. PMID- 29183797 TI - Increase in Ca2+ current by sustained cAMP levels enhances proliferation rate in GH3 cells. AB - AIMS: Ca2+ and cAMP are important intracellular modulators. In order to generate intracellular signals with various amplitudes, as well as different temporal and spatial properties, a tightly and precise control of these modulators in intracellular compartments is necessary. The aim of this study was to evaluate the effects of elevated and sustained cAMP levels on voltage-dependent Ca2+ currents and proliferation in pituitary tumor GH3 cells. MAIN METHODS: Effect of long-term exposure to forskolin and dibutyryl-cyclic AMP (dbcAMP) on Ca2+ current density and cell proliferation rate were determined by using the whole-cell patch clamp technique and real time cell monitoring system. The cAMP levels were assayed, after exposing transfected GH3 cells with the EPAC-1 cAMP sensor to forskolin and dbcAMP, by FRET analysis. KEY FINDINGS: Sustained forskolin treatment (24 and 48h) induced a significant increase in total Ca2+ current density in GH3 cells. Accordingly, dibutyryl-cAMP incubation (dbcAMP) also elicited increase in Ca2+ current density. However, the maximum effect of dbcAMP occurred only after 72h incubation, whereas forskolin showed maximal effect at 48h. FRET-experiments confirmed that the time-course to elevate intracellular cAMP was distinct between forskolin and dbcAMP. Mibefradil inhibited the fast inactivating current component selectively, indicating the recruitment of T-type Ca2+ channels. A significant increase on cell proliferation rate, which could be related to the elevated and sustained intracellular levels of cAMP was observed. SIGNIFICANCE: We conclude that maintaining high levels of intracellular cAMP will cause an increase in Ca2+ current density and this phenomenon impacts proliferation rate in GH3 cells. PMID- 29183798 TI - Altered membrane integrity in the progression of muscle diseases. AB - Sarcolemmal integrity is orchestrated through the interplay of preserving membrane strength and fast tracking the membrane repair process during an event of compromised membrane fragility. Several molecular players have been identified that act in a concerted fashion to maintain the barrier function of the muscle membrane. Substantial research findings in the field of muscle biology point out the importance of maintaining membrane integrity as a key contributory factor to cellular homeostasis. Innumerable data on the progression of membrane pathology associated with compromised muscle membrane integrity support targeting sarcolemmal integrity in skeletal and cardiac muscle as a model therapeutic strategy to alleviate some of the pathologic conditions. This review will discuss strategies that researchers have undertaken to compensate for an imbalance in sarcolemma membrane fragility and membrane repair to maintain muscle membrane integrity. PMID- 29183799 TI - Is testicular dysgenesis syndrome a genetic, endocrine, or environmental disease, or an unexplained reproductive disorder? AB - Progressive increases in the incidence of male reproductive disorders inclusive of hypospadias, cryptorchidism, poor semen quality, and testicular germ cell cancer (TGCC) have been observed in recent times. The central hypothesis of this study asserted that these disorders may all collectively signify testicular dysgenesis syndrome (TDS). This review aimed to provide evidence verifying the reality of TDS based on four key aspects: environmental endocrine-disrupting chemicals (EDCs), genetic factors, intrauterine growth disorders and lifestyle factors. Although TDS might result from genetic polymorphisms or aberration, recent evidence has highlighted links indicating the conditions associations to both environmental and lifestyle factors due to the rapid temporal changes in the clinical symptoms observed over recent decades. Based on our review of genetic and environmental factors, a key observation of our study suggested that there is an urgent need to prioritize research in reproductive physiology and pathophysiology, particularly in highly industrialized countries facing decreasing populations. At present, current research has yet to elucidate the mechanisms of TDS, in addition to the lack of genuine consideration of a variety of potentially key factors and TDS mechanisms. In conclusion, our study revealed that environmental exposures owing to modern lifestyles are primary factors involved in the associated trends of the syndrome, which are capable of affecting the adult endocrine system via direct means or through epigenetic mechanisms. PMID- 29183800 TI - Formulations based on solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) for cutaneous use: A review. AB - Cutaneous use of lipid nanoparticles (solid lipid nanoparticles, SLN and nanostructured lipid carriers, NLC) has been showing promising results. These systems consist of low viscosity aqueous dispersions, being usually employed by means of semi-solid formulations with adequate consistency for skin application. This review addresses the cutaneous use of lipid nanoparticles for therapeutic and cosmetic applications. Initially, general information related to pharmaceutical semi-solid formulations is presented. Afterwards, the effects of SLN and NLC on the skin, and technological aspects related to semi-solid systems based on SLN or NLC are described. Finally, the most relevant studies related to the formulations based on SLN and NLC, for cosmetic and therapeutic applications, are reported. Notwithstanding the cutaneous use of SLN and NLC has been proposed for both local and transdermal delivery, the reported studies show promising results only for local application. In this sense, more research is required to better understanding the interaction mechanisms of lipid nanoparticles with skin lipids. Furthermore, the development of standard methods for skin experiments with nanoparticles is necessary. PMID- 29183801 TI - Cryptococcus neoformans peritonitis in the cirrhotic patient. PMID- 29183802 TI - Zika virus: An emerging player in the global scenario. PMID- 29183803 TI - 8-Nitro-cGMP is a promoter of osteoclast differentiation induced by RANKL. AB - Osteoclasts are multinucleated giant cells differentiated from monocyte macrophage-lineage cells under stimulation of receptor activator of nuclear factor kappa-B (RANK) ligand (RANKL) produced by osteoblasts and osteocytes. Although it has been reported that nitric oxide (NO) and reactive oxygen species (ROS) are involved in this process, the mechanism by which these labile molecules promote osteoclast differentiation are not fully understood. In this study, we investigated the formation and function of 8-nitro-cGMP, a downstream molecule of NO and ROS, in the process of osteoclast differentiation in vitro. 8-Nitro-cGMP was detected in mouse bone marrow macrophages and osteoclasts differentiated from macrophages in the presence of RANKL. Inhibition of NO synthase suppressed the formation of 8-nitro-cGMP as well as RANKL-induced osteoclast differentiation from macrophages. On the other hand, RANKL-induced osteoclast differentiation was promoted by addition of 8-nitro-cGMP to the cultures. In addition, 8-nitro-cGMP enhanced the mRNA expression of RANK, the receptor for RANKL. However, 8-bromo cGMP, a membrane-permeable derivative of cGMP, did not have an effect on either RANKL-induced osteoclast differentiation or expression of the RANK gene. These results suggest that 8-nitro-cGMP is a novel positive regulator of osteoclast differentiation, which might help to explain the roles of NO and ROS in osteoclast differentiation. PMID- 29183804 TI - Modulation of nNOSser852 phosphorylation and translocation by PKA/PP1 pathway in endothelial cells. AB - Neuronal nitric oxide synthase (nNOS) is now considered an important player in vascular function. It has a protective role in atherosclerosis and hypertension. However, despite its importance, little is known about the mechanisms that regulate its activity in vascular cells. Here we explore the mechanisms by which nNOS is activated in endothelium. We evaluated aorta relaxation response and phosphorylation of nNOS during protein phosphatases 1 and 2 (PP1 and PP2) inhibition, in eNOS silenced mice. PP1 translocation and interaction between the nuclear inhibitor of PP1 (NIPP1) and PP1 was evaluated in endothelial EA.hy926 cells. We demonstrate here that acetylcholine (Ach)-induced relaxation is completely abolished by nNOS inhibition in eNOS silenced mice aorta which also decreased NO and H2O2 concentrations. ACh induced dephosphorylation of nNOSser852 in aorta after 20 min stimulation. Endothelial cells also showed a decrease in nNOSser852 phosphorylation during 20 min of ACh stimulation. PP2 inhibition had no effect on Ach-induced nNOSSer852 dephosphorylation in endothelial cells and did not modify Ach-induced vasodilation in aorta from eNOS silenced mice. Non selective PP1/PP2 inhibition prevented nNOSSer852 dephosphorylation in endothelial cells and prevented Ach-induced vasodilation in eNOS silenced mice. ACh induced time-dependent PP1 and NIPP1 dissociation and PP1 translocation to cytoplasm. Protein kinase A (PKA) inhibition abolished PP1 translocation and further nNOSser852 dephosphorylation. In addition, 8-Br-cAMP reduced NIPP1/PP1 interaction, stimulated PP1 translocation and nNOSser852 dephosphorylation. Moreover, PKA Inhibition led to a decreased nNOS translocation to perinuclear region. Taken together, our results elucidate a mechanism whereby PP1 is activated by a cAMP/PKA-dependent pathway, leading to dephosphorylation of nNOSser852 and subsequent NO and possible H2O2 production resulting in endothelium-dependent vascular relaxation. PMID- 29183805 TI - Proteome profiles of different types of thyroid cancers. AB - Proteomics profiling of tissue specimens representative for major types of thyroid cancers: papillary (classical and follicular variant), follicular, anaplastic and medullary, as well as benign follicular adenoma, was performed using shotgun LC-MS/MS approaches. A combination of Orbitrap and MALDI-TOF approach allowed to identify protein products of 3700 unique genes and revealed large differences between medullary, anaplastic and epithelium-derived differentiated cancers (papillary and follicular). Proteins characteristic for medullary and anaplastic cancers included factors associated with neuroendocrine functions and factors typically associated with advanced malignancies, respectively. Proteomes of different types of epithelium-derived differentiated cancers and follicular adenoma were compared using multi-enzyme LC-MS/MS approach, which revealed products of 4800 unique genes. A comparable overall similarity of follicular cancers to both variants of papillary cancers was found. Moreover, follicular adenoma showed higher overall similarity to follicular cancer than to either variant of papillary cancer. Proteins discriminating differentiated thyroid neoplasms included factors associated with lipid and hormone metabolism, regulation of gene expression and maintenance of DNA structure. Importantly, proteome data matched several features of transcriptome and metabolome profiles of thyroid cancers contributing to systems biology of this malignancy. PMID- 29183806 TI - The antagonist properties of Bazedoxifene after acute treatment are shifted to stimulatory action after chronic exposure in the liver but not in the uterus. AB - A promising alternative to conventional hormone therapy for postmenopausal symptoms is treatment combining Bazedoxifene (BZA), a third-generation selective estrogen receptor modulator (SERM), and conjugated equine estrogen (CE). This combination is also known as a tissue-selective estrogen complex (TSEC). Understanding the tissue-specific actions of SERMs and the TSEC remains a major challenge to try to predict their clinical effects. The aim of this study was to compare acute versus chronic treatment with BZA, CE or CE + BZA in two major targets of estrogens, the uterus and the liver. In these two tissues, acute treatment with CE, but not with BZA, induced similar gene expression change than the most important endogenous estrogen, 17-beta estradiol (E2). Acute induction of gene expression by E2 or by CE was antagonized by the addition of BZA. Concomitantly, BZA alone or in combination with E2 or CE induced a partial degradation of ERalpha protein after acute exposure. In uterus, chronic treatment of BZA alone had no impact on tissue weight gain or on epithelial cell proliferation, and also antagonized CE-effect in uterus, thereby mimicking the acute effect. By contrast, in the liver, chronic BZA and CE + BZA elicited agonistic transcriptional effects similar to those of CE alone. In addition, at variance to BZA acute effect, no change in ERalpha protein abundance was observed after chronic treatment in this tissue. These experimental in vivo data highlight a new aspect of the time-dependent tissue-specific action of BZA or TSEC, i.e. they can act acutely as antagonists but become agonists after chronic treatment. This shift was observed in liver tissue, but not in proliferative sex target such as the uterus. PMID- 29183807 TI - Neonatal overfeeding increases capacity for catecholamine biosynthesis from the adrenal gland acutely and long-term in the male rat. AB - A poor nutritional environment during early development has long been known to increase disease susceptibility later in life. We have previously shown that rats that are overfed as neonates (i.e. suckled in small litters (4 pups) relative to control conditions (12 pups)) show dysregulated hypothalamic-pituitary-adrenal axis responses to immune stress in adulthood, particularly due to an altered capacity of the adrenal to respond to an immune challenge. Here we hypothesised that neonatal overfeeding similarly affects the sympathomedullary system, testing this by investigating the biochemical function of tyrosine hydroxylase (TH), the first rate-limiting enzyme in the catecholamine synthesis. We also examined changes in adrenal expression of the leptin receptor and in mitogen-activated protein kinase (MAPK) signalling. During the neonatal period, we saw age dependent changes in TH activity and phosphorylation, with neonatal overfeeding stimulating increased adrenal TH specific activity at postnatal days 7 and 14, along with a compensatory reduction in total TH protein levels. This increased TH activity was maintained into adulthood where neonatally overfed rats exhibited increased adrenal responsiveness 30 min after an immune challenge with lipopolysaccharide, evident in a concomitant increase in TH protein levels and specific activity. Neonatal overfeeding significantly reduced the expression of the leptin receptor in neonatal adrenals at postnatal day 7 and in adult adrenals, but did not affect MAPK signalling. These data suggest neonatal overfeeding alters the capacity of the adrenal to synthesise catecholamines, both acutely and long term, and these effects may be independent of leptin signalling. PMID- 29183808 TI - The vitamin D receptor (VDR) binds to the nuclear matrix via its hinge domain: A potential mechanism for the reduction in VDR mediated transcription in mitotic cells. AB - Vitamin D is best known for its regulation of calcium homeostasis. Vitamin D exerts its genomic actions via the vitamin D receptor (VDR). As a member of the superfamily of nuclear receptors (NR), the VDR is primarily located within the nucleus of non-dividing cells. We show here that the VDR relocates from the nucleus into the cytoplasm across all stages of cell division in CHO cells. Furthermore, we show that the VDR is transcriptionally inert during cell division. In addition, 1alpha, 25 dihydroxyvitamin D (1,25(OH)2D3) promotes VDR binding to the nuclear matrix. Finally, we assessed the structural nature of VDR binding to the nuclear matrix. Mutation of the hinge domain reduced VDR's ability to bind to the nuclear matrix and to initiate transcription in response to 1,25(OH)2D3. Taken together, our data suggest that the association between the VDR and the nuclear matrix accounts for the apparent cytosolic distribution as the matrix disperses within the cytoplasm when cells divide. This may also explain the dramatic reduction in VDR mediated transcription during cell division. Our data also confirm that similar to other NRs, the hinge domain of the VDR is responsible for this association. PMID- 29183809 TI - The effects of high glucose exposure on global gene expression and DNA methylation in human pancreatic islets. AB - BACKGROUND: Type 2 diabetes (T2D) is a complex disease characterised by chronic hyperglycaemia. The effects of elevated glucose on global gene expression in combination with DNA methylation patterns have not yet been studied in human pancreatic islets. Our aim was to study the impact of 48 h exposure to high (19 mM) versus control (5.6 mM) glucose levels on glucose-stimulated insulin secretion, gene expression and DNA methylation in human pancreatic islets. RESULTS: While islets kept at 5.6 mM glucose secreted significantly more insulin in response to short term glucose-stimulation (p = 0.0067), islets exposed to high glucose for 48 h were desensitised and unresponsive to short term glucose stimulation with respect to insulin secretion (p = 0.32). Moreover, the exposure of human islets to 19 mM glucose resulted in significantly altered expression of eight genes (FDR<5%), with five of these (GLRA1, RASD1, VAC14, SLCO5A1, CHRNA5) also exhibiting changes in DNA methylation (p < 0.05). A gene set enrichment analysis of the expression data showed significant enrichment of e.g. TGF-beta signalling pathway, Notch signalling pathway and SNARE interactions in vesicular transport; these pathways are of relevance for islet function and possibly also diabetes. We also found increased DNA methylation of CpG sites annotated to PDX1 in human islets exposed to 19 mM glucose for 48 h. Finally, we could functionally validate a role for Glra1 in insulin secretion. CONCLUSION: Our data demonstrate that high glucose levels affect human pancreatic islet gene expression and several of these genes also exhibit epigenetic changes. This might contribute to the impaired insulin secretion seen in T2D. PMID- 29183810 TI - Identification, structural characterization, and expression analysis of toll-like receptors 2 and 3 from gibel carp (Carassius auratus gibelio). AB - Toll-like receptors (TLRs) are important components of innate immunity. TLRs recognize pathogen-associated molecular patterns (PAMPs) and initiate downstream signaling pathways in response. In present study, we report the identification of two TLRs from gibel carp (Carassius auratus gibelio), TLR2 and TLR3 (designated CagTLR2 and CagTLR3, respectively). We report on the genomic structures and mRNA expression patterns of CagTLR2 and CagTLR3. Five exons and four introns were identified from the genomic DNA sequence of CagTLR3 (4749 bp in total length); this genomic organization is similar to that of TLR3 in zebrafish and human. However, only one intron was identified from the CagTLR2 genomic locus (3166 bp in total length); this unique genomic organization of CagTLR2 is different from that of TLR2 in fish and humans. The cDNAs of CagTLR2 and CagTLR3 encoded 791 and 904 amino acid residues, respectively. CagTLR2 and CagTLR3 contained two distinct structural/functional motifs of the TLR family: a leucine-rich repeat (LRR) domain in the extracellular portion and a toll/interleukin-1 receptor (TIR) domain in the intracellular portion. The positions of critical amino acid residues involed in PAMP recognition and signaling pathway transduction in mammalian TLRs were conserved in CagTLR2 and CagTLR3. Phylogenetic analysis revealed a closer clustering of CagTLR2 and CagTLR3 with TLRs from freshwater fish than with marine fish species. In healthy gibel carp, transcripts of these genes were detected in all examined tissues, and high expression levels of CagTLR2 and CagTLR3 were observed in liver and brain, respectively. Following injection with CyHV-2, expression levels of CagTLR2 and CagTLR3 were significantly upregulated in the spleens of gibel carp after three days, and CagTLR3 transcript levels were rapidly increased in head kidney after 12 h. These results suggest that CagTLR2 and CagTLR3 are functionally involved in the induction of antiviral immune response. PMID- 29183811 TI - TO17: A teleost antimicrobial peptide that induces degradation of bacterial nucleic acids and inhibits bacterial infection in red drum, Sciaenops ocellatus. AB - Tissue factor pathway inhibitor (TFPI)-1 is well known for its role as an inhibitor of blood coagulation. Several studies have demonstrated that the C terminal peptides of TFPI-1 are active against a broad spectrum of microorganisms. In a previous study, we found that TO17 (with 17 amino acids), a TFPI-1 C-terminal peptide from red drum (Sciaenops ocellatus), was active against Edwardsiella tarda. In the present study, we investigated further the antimicrobial spectrum, action mode, as well as the immunostimulatory property of TO17. Our results showed that TO17 displayed antimicrobial activity against Staphylococcus aureus, Micrococcus luteus, Vibrio vulnificus, and infectious spleen and kidney necrosis virus, independent of host serum. Furthermore, the activity of TO17 was influenced by the length or type of amino acids at the N and C termini. During its interaction with V. vulnificus, TO17 exerted its antibacterial activity by destroying cell membrane integrity, penetrating the cytoplasm and inducing degradation of genomic DNA and total RNA. In addition, TO17 had no hemolytic activity against red drum blood cells. In vitro, TO17 enhanced production of nitric oxide and bactericidal activity of red drum macrophages. In vivo, administration of red drum with TO17 before bacterial infection significantly reduced pathogen dissemination and replication in tissues. These results indicate that TO17 is a broad-spectrum antimicrobial peptide with immunostimulatory properties and it has the potential to be used as an antimicrobial agent in aquaculture.

AB - Bamboo (Melocanna baccifera) plant plays a significant role in traditional Asian medicine and it can be used as an alternative to various chemo-therapeutics or prophylactic agents used in aquaculture. In the present study, the 1st experiment was done for the preparation of extracts from bamboo leaves by using 90% alcohol as a solvent. In the 2nd experiment, toxicity study was carried on Labeo rohita fingerlings (average length of 10.3 +/- 1.5 cm and weight 18.5 +/- 1.5 g) using BLAL (Bamboo Leaf Alcoholic) extract and it did not show any mortalities in fish even at the dose of 20 g kg-1 body weight, which can be regarded as virtually non toxic with minimal effect. The 3rd experiment was conducted to find out the effect of BLAL extract based isocaloric and isonitrogenous feed (doses: control- 0.0%, diet T1-0.01%, diet T2-0.1%, diet T3-1% BLAL extract kg-1 feed) on the haemato-immuno-biochemical parameters of L. rohita fingerlings (average length 15.7 +/- 1.5 cm and weight 20.2 +/- 1.5 g). Regular sampling was done (on 7th, 15th, 30th and 60th day of feeding) for different haematological, immunological and biochemical parameters. The study revealed that the best response occurred within 7 days of feeding with BLAL extract and long-term feeding have shown immunosuppressive condition in the fish. In the 4th experiment, fish were exposed to multiple stressors like low pH stress, and Saprolegnia parastica infection after feeding with BLAL extract (0.1%) based feed for 7 days. The study showed that the BLAL extract can make fish resistant to single stress however, not able to reduce the fish mortality under multiple stresses (S. parastica infection under low pH). Thus, it can be concluded that the BLAL has the potentiality to be used as a non-toxic phyto-prophylactic which can induce non-specific immune response, reduces the low pH stress responses and increases the resistance against saprolegniasis under neutral pH condition in rohu fingerlings. PMID- 29183813 TI - Reduced glutathione supplementation in practical diet improves the growth, anti oxidative capacity, disease resistance and gut morphology of shrimp Litopenaeus vannamei. AB - The present study was conducted to investigate the effects of reduced glutathione (GSH) supplementation in practical diet on growth performance, anti-oxidative response, disease resistance and intestine morphology of shrimp Litopenaeus vannamei. Two control diets based on the commercial formulation were designed with high level (27%) and low level (22%) of fish meal, respectively. Based on the control diet with low level of fish meal, 75, 150 and 225 mg/kg of GSH were added, respectively, to make the other three experimental diets. The five formulated diets were named as C1, C2, G1, G2 and G3, respectively. The shrimp (initial body weight: 0.30 +/- 0.02 g) were fed with the five experimental diets for 8 weeks followed by a challenge test with Vibrio parahaemolyticus. The results showed that the specific growth rate (SGR) of shrimp in the C2 group was significantly lower than that in C1. The SGRs in G1 and G2 had no significant difference with those in C1 and C2. However, the SGR in G3 was significantly lower than that in C1. The serum GSH concentration in C2 was significantly lower than the other groups, but the malondialdehyde concentration was significantly higher. The supplementation of dietary GSH significantly improved the total anti oxidative capacity and activities of glutathione S-transferase and glutathione peroxidase in serum. The villus height of intestine in the GSH supplemented groups had no significant difference with C1, but was significantly higher than C2. The jejunum wall thickness of intestine in G2 and G3 was significantly higher than those in the other groups. After the challenge test, the cumulative mortalities in G1 and G2 were significantly lower than C1 and C2. However, there was no significant difference in cumulative mortalities among G3, C1 and C2. In conclusion, based on the present experimental conditions, 75-150 mg/kg of GSH was suggested to be supplemented into the practical diet to improve the growth, anti oxidative capacity, disease resistance and gut health of shrimp L. vannamei. PMID- 29183815 TI - Bioscavenger is effective as a delayed therapeutic intervention following percutaneous VX poisoning in the guinea-pig. AB - The prolonged systemic exposure that follows skin contamination with low volatility nerve agents, such as VX, requires treatment to be given over a long time due to the relatively short half-lives of the therapeutic compounds used. Bioscavengers, such as butyrylcholinesterase (BChE), have been shown to provide effective post-exposure protection against percutaneous nerve agent when given immediately on signs of poisoning and to reduce reliance on additional treatments. In order to assess the benefits of administration of bioscavenger at later times, its effectiveness was assessed when administration was delayed for 2h after the appearance of signs of poisoning in guinea-pigs challenged with VX (4*LD50). VX-challenged animals received atropine, HI-6 and avizafone on signs of poisoning and 2h later the same combination with or without bioscavenger. Five out of 6 animals which received BChE 2h after the appearance of signs of poisoning survived to the end of the study at 48h, compared with 6 out of 6 which received BChE immediately on signs. All the animals (n=6+6) that received only MedCM, without the addition of BChE, died within 10h of poisoning. The toxicokinetics of a sub-lethal challenge of percutaneous VX were determined in untreated animals. Blood VX concentration peaked at approximately 4h after percutaneous dosing with 0.4*LD50; VX was still detectable at 36h and had declined to levels below the lower limit of quantification (10pg/mL) by 48h in 7 of 8 animals, with the remaining animal having a concentration of 12pg/mL. These studies confirm the persistent systemic exposure to nerve agent following percutaneous poisoning and demonstrate that bioscavenger can be an effective component of treatment even if its administration is delayed. PMID- 29183814 TI - Sulfur mustard resistant keratinocytes obtained elevated glutathione levels and other changes in the antioxidative defense mechanism. AB - BACKGROUND: Sulfur mustard (SM) is a potent blistering chemical warfare agent, which was first used in 1917. Despite the Chemical Weapons Convention, a use was recently reported in Syria in 2015. This emphasizes the importance to develop countermeasures against chemical warfare agents. Despite intensive research, there is still no antidote or prophylaxis available against SM. METHODS: The newly developed SM-resistant keratinocyte cell line HaCaT/SM was used to identify new target structures for drug development, particularly the adaptations in protective measures against oxidative stress. For this purpose, glutathione (GSH) and NAD(P)H levels, the effect of glutathione S-transferase (GST) inhibition as well as activation and expression of Nrf2, GST, glutamate cysteine ligase (GCL) and glutathione-disulfide reductase (GSR) as well as multi-drug resistance (MDR) proteins 1, 3 and 5 were investigated. RESULTS: The HaCaT/SM cells showed not only a better survival after treatment with SM or cytostatic drugs, but also hydrogen peroxide (H2O2). They exhibit more GSH even after SM treatment. Nrf2 levels were significantly lower. Inhibition of GST led to significantly decreased, activation to slightly higher IC50 values after SM treatment and a lower expression of GST was observed. The cells also expressed less GCLC and GSR. Expression of MDR1, MDR3 and MDR5 was higher under control conditions, but less stimulated by SM treatment. An increased NADP+/NADPH ratio as well as higher NAD+ levels were shown. CONCLUSION: In summary, an improved response of the resistant cell line to oxidative stress was observed. The underlying mechanisms are elevated GSH levels as well as lower expression of Nrf2 and its targets GCLC and GST as well as GSR and MDR1, MDR3 and MDR5. GST is an especially interesting target because its inhibition already induced a significant SM sensitivity. SM resistance also caused redox equivalent level differences. Taken together, these findings provide further insight into the mechanism of SM resistance and may open a window for novel therapeutic targets in SM therapy. PMID- 29183816 TI - Evaluation of diffusion weighted imaging in the context of multi-parametric MRI of the prostate in the assessment of suspected low volume prostatic carcinoma. AB - Data from a multi-parametric MRI study of patients with possible early-stage prostate cancer was assessed with a view to creating a more efficient clinical protocol. Based on a correlation analysis suggesting that diffusion-weighted imaging (DWI) scores are more strongly correlated with overall PIRADS scores than other modalities such as dynamic contrast enhanced imaging or spectroscopy, we investigate the combination of T2-weighted imaging (T2w) and DWI as a potential diagnostic tool for prostate cancer detection, staging and guided biopsies. Quantification of the noise floor in the DWI images and careful fitting of the data suggests that the mono-exponential model provides a very good fit to the data and there is no evidence of non-Gaussian diffusion for b-values up to 1000s/mm2. This precludes the use of kurtosis or other non-Gaussian measures as a biomarker for prostate cancer in our case. However, the ADC scores for healthy and probably malignant regions are significantly lower for the latter in all 20 but one patient. The results suggest that a simplified mp-MRI protocol combining T2w and DWI may be a good compromise for a cost and time efficient, early-stage prostate cancer diagnostic programme, combining robust MR biomarkers for prostate cancer that can be reliably quantified and appear well-suited for general clinical practice. PMID- 29183817 TI - Structural characterization of a lepidopteran type-II farnesyl diphosphate synthase from the spruce budworm, Choristoneura fumiferana: Implications for inhibitor design. AB - Farnesyl diphosphate synthase (FPPS) is an enzyme from the class of short chain (E)-prenyltransferases that catalyzes the condensation of two molecules of isopentenyl diphosphate (IPP, C5) with dimethylallyl diphosphate (DMAPP, C5) to generate the C15 product FPP. In insects, FPPS plays a key role in the biosynthesis of the morphogenetic and gonadotropic "juvenile hormone" (JH). Lepidopteran genomes encode two very distinct FPPS paralogs, one of which ("type II") is expressed almost exclusively in the JH-producing glands, the corpora allata. This paralog has been hypothesized to display structural features that enable the binding of the bulkier precursors required for the biosynthesis of lepidopteran ethyl-branched JHs. Here, we report on the first crystal structures of an insect FPPS solved to date. Apo, ligand-bound, and inhibitor-bound structures of type-II FPPS (FPPS2) from the spruce budworm, Choristoneura fumiferana (Order: Lepidoptera), were obtained. Comparison of apo and inhibitor bound enzymes revealed differences in both inhibitor binding and structural plasticity of CfFPPS2 compared to other FPPSs. Our data showed that IPP is not essential to the closure of the C-terminal tail. Ortho-substituted pyridinium bisphosphonates, previously shown to inhibit CfFPPS2, bound to the allylic site, as predicted; however, their alkyl groups were oriented towards the homoallylic binding site, with the bulkier propyl-substituted inhibitor penetrating deeply into the IPP binding pocket. The current study sheds light on the structural basis of substrate specificity of type-II FPPS of the spruce budworm. Through a comparison with other inhibitor-bound FPPSs, we propose several approaches to improve inhibitor selectivity and potency. PMID- 29183818 TI - Federal and State Policy Efforts to Address Maternal Opioid Misuse: Gaps and Challenges. AB - BACKGROUND: Opioid misuse during pregnancy is increasingly common and is associated with preterm birth and neonatal abstinence syndrome. As such, there is increased policy attention on reducing opioid misuse and increasing detection and treatment of opioid use disorder around the time of childbirth. METHODS: We conducted a review of peer-reviewed and grey literature to identify policy strategies to address opioid misuse among pregnant women; to describe current federal and state laws that impact women before pregnancy, during pregnancy, at birth, and postpartum; and to identify gaps and challenges related to these efforts. RESULTS: We identify two gaps in current efforts: 1) limited attention to prevention of opioid misuse among reproductive-age women, and 2) lack of policies addressing opioid misuse among postpartum women. We also discuss barriers to accessing care for women who misuse opioids, including provider shortages (e.g., too few addiction medicine specialists accept pregnant women or Medicaid beneficiaries as patients), logistical barriers (e.g., lack of transportation, child care), stigma, and fear of legal consequences. CONCLUSIONS: As policymakers pursue strategies to address the opioid epidemic, the unique needs of pregnant and postpartum women and barriers to treatment should be addressed. PMID- 29183820 TI - MHC class II DRB diversity predicts antigen recognition and is associated with disease severity in California sea lions naturally infected with Leptospira interrogans. AB - We examined the associations between California sea lion MHC class II DRB (Zaca DRB) configuration and diversity, and leptospirosis. As Zaca-DRB gene sequences are involved with antigen presentation of bacteria and other extracellular pathogens, we predicted that they would play a role in determining responses to these pathogenic spirochaetes. Specifically, we investigated whether Zaca-DRB diversity (number of genes) and configuration (presence of specific genes) explained differences in disease severity, and whether higher levels of Zaca-DRB diversity predicted the number of specific Leptospira interrogans serovars that a sea lion's serum would react against. We found that serum from diseased sea lions with more Zaca-DRB loci reacted against a wider array of serovars. Specific Zaca DRB loci were linked to reactions with particular serovars. Interestingly, sea lions with clinical manifestation of leptospirosis that had higher numbers of Zaca-DRB loci were less likely to recover from disease than those with lower diversity, and those that harboured Zaca-DRB.C or -G were 4.5 to 5.3 times more likely to die from leptospirosis, regardless of the infective serovars. We propose that for leptospirosis, a disadvantage of having a wider range of antigen presentation might be increased disease severity due to immunopathology. Ours is the first study to examine the importance of Zaca-DRB diversity for antigen detection and disease severity following natural exposure to infective leptospires. PMID- 29183819 TI - SMFM Special Report: Putting the "M" back in MFM: Reducing racial and ethnic disparities in maternal morbidity and mortality: A call to action. AB - Racial and ethnic disparities in maternal morbidity and mortality rates are an important public health problem in the United States. Because racial and ethnic minorities are expected to comprise more than one-half of the US population by 2050, this issue needs to be addressed urgently. Research suggests that the drivers of health disparities occur at 3 levels: patient, provider, and system. Although we have recognized this issue and identified elements that contribute to it, knowledge must be converted into action to address it. In addition, despite available funding and databases, research directed towards understanding and reducing these disparities is lacking. This document summarizes findings of a workshop convened at the 2016 Society for Maternal-Fetal Medicine's 36th Annual Pregnancy meeting in Atlanta, GA, to review and make recommendations about immediate actions in clinical care and research that will serve to reduce racial and ethnic disparities in maternal morbidity and mortality rates in the United States. PMID- 29183821 TI - Quality of life after total knee arthroplasty. AB - Total knee arthroplasty (TKA) results in a high degree of patient satisfaction, as it provides patients with considerable medium- and long-term benefits in terms of quality of life, pain relief and function. Nevertheless, the literature reports that up to 30% of patients are dissatisfied. This dissatisfaction is directly related to the patients' quality of life, which they deem insufficient. Their quality of life depends on many physical, behavioural, social and psychological factors that are not taken into account by functional outcome scores. After describing the principles of quality of life evaluation after TKA, we will assess the effects of patient-related factors, the surgical technique and postoperative program through an exhaustive review of the literature. Patient expectations after TKA will then be outlined, particularly return to work and return to sports. PMID- 29183822 TI - Treatment of aseptic tibial shaft non-union without bone defect. AB - Non-union is incomplete consolidation of a fracture, without effective formation of a uniting callus. Despite better understanding of the physiology of bone consolidation, management of tibial non-union remains a challenge for orthopedic surgeons. Several treatments have been developed in recent decades, and we now have a range of techniques, with indications based on type of non-union, prior treatments, available equipment, and the surgeon's experience. Firstly, there are surgical techniques such as osteo-periosteal decortication, cancellous iliac graft, or inter-tibiofibular graft. The decision to fix the non-union (or revise existing fixation) and choice of type of internal fixation depend on the stability of the fracture site. There are also non-operative biological and biochemical consolidation stimulation techniques: local injection of bone-marrow, platelet-rich plasma (PRP) or bone morphogenetic protein (BMP). Stimulation can also be physical, applying ultrasound or an electromagnetic field to the non union site. Each technique may be used in isolation or association. PMID- 29183823 TI - Lip reconstruction technique: A modified Abbe-Estlander with a myomucosal advancement flap. AB - Lip cancer represents between 12-15% of all oral cavity cancers; 95% affect the lower lip. The main objectives in lip reconstruction after tumoral mass resection are functionality and esthetics. We present the case of an 81-year-old male with a past medical history of squamous cell carcinoma of the maxilla. The patient consults with the Maxillofacial Surgery Department due to a hypertrophic lesion in the left oral commissure. The defect is considered intermediate in size (between 50% and two-thirds). For reconstruction of the lip, a classical rotation flap (Estlander flap) is used together with a myomucosal flap, which is both innervated and expandable. According to medical literature, for intermediate defects of the lower lip advancement or rotation flaps should be used. One of these is the Abbe-Estlander flap, a rotation flap dependent of the superior or the inferior labial artery. The Karapandzic flap and Johansen's staircase flap are other recommended techniques. PMID- 29183824 TI - Zika virus infection in travelers returning from countries with local transmission, Guangdong, China, 2016. AB - BACKGROUND: Zika virus (ZIKV) is a mosquito-borne virus spreading rapidly in the Americas, Africa, and Asia. No indigenous ZIKV infection had been seen in China. We monitored ZIKV infection among travelers returning to Enping county from ZIKV transmitting countries from 1 March to 10 April 2016. METHODS: We analyzed data including interviews; conducted laboratory test on blood, urine, saliva, conjunctival swab or semen specimens for evidence of ZIKV infection; evaluated household for presence of Aedes mosquitoes or larvae. RESULTS: A total of 925 individuals were screened, 507 (54.8%) were interviewed, 400 (43.2%) provided samples, of which 13 (3.3%) tested positive for ZIKV including 3 asymptomatic. Rash, conjunctivitis, sore throat, fever were the common symptoms; rash was more pronounced in adults than in children. ZIKV RNA was detected for 1-4 days in blood, but longer in urine and saliva (3-32 days and 2-10 days). Among interviewed, 57.0% had good knowledge about ZIKV, 45.8% were worried about ZIKV, 99.2% would go to hospital if they had infection. Aedes mosquitoes or larvae were detected in townships of infected returners. CONCLUSIONS: ZIKV was imported to China. Screening by symptoms alone is inadequate for detecting ZIKV infection. ZIKV surveillance, health-education, and vector control are necessary to decrease risk of ZIKV transmission. PMID- 29183825 TI - Chronic Intranasal Oxytocin has Dose-dependent Effects on Central Oxytocin and Vasopressin Systems in Prairie Voles (Microtus ochrogaster). AB - Oxytocin (Oxt) is a neuropeptide with many functions, including modulation of social behavior(s) and anxiety. Due to its notable pro-social effects, it has been proposed as a treatment in the management of neuropsychiatric disorders, such as autism spectrum disorder (ASD), schizophrenia, and social anxiety; however, effects of long-term daily treatment are still being explored. Previously, we have shown that in male prairie voles (Microtus ochrogaster) exposure to Oxt during the peri-adolescent period impaired adult pair bonding in a dose-dependent fashion. In females, the medium dose used (0.8 IU/kg) appeared to facilitate pair bonding, and the low and medium doses were associated with fewer lines crossed in the open field. In this study, we examined central receptor binding and immunoreactive (IR) protein for Oxt and vasopressin (Avp), a closely related peptide. Voles were treated with saline vehicle, or one of three doses of Oxt (0.08, 0.8, 8.0 IU/kg) for three weeks from postnatal days 21 to 42, and euthanized as adults. We used autoradiography to examine Oxt and Avp receptor binding and immunohistochemistry to examine Oxt and Avp - IR cells in the paraventricular (PVN) and supraoptic (SON) nuclei of the hypothalamus. Females that received the medium dose of Oxt had higher Oxt receptor binding in the nucleus accumbens shell (NAS), while males that received the medium dose had lower Avp-IR cells in the PVN. In summary, we found sex-specific effects of long term exposure to intranasal Oxt on the Oxt and Avp systems at the weight-adjusted dose currently being used in clinical trials in humans. PMID- 29183827 TI - Complex Environmental Rearing Enhances Social Salience and Affects Hippocampal Corticotropin Releasing Hormone Receptor Expression in a Sex-Specific Manner. AB - Methods for understanding the neurocircuitry of ethologically relevant behaviors have advanced substantially; however renovations to standard animal laboratory housing, in the form of enhanced enrichment, have lagged behind. This is despite evidence that environmental enrichment (EE) reduces stress, stereotypy, and promotes healthy species typical behaviors. While many scientists express interest for increased EE as a standard for animal caging systems, there are concerns that its effects on brain, behavior, and cognition are not well characterized. In the present study, male and female Sprague-Dawley rats were housed for six weeks in either EE, Colony Nesting (CN), or Standard Housing (SD) conditions. We show that adolescent exposure to environmental complexity changed the dynamics of social interactions, sensory processing, and underlying basal stress neurocircuitry, in a sex- and enrichment-type-dependent manner. Specifically, EE and CN increased prosocial engagement and the social saliency of male and female rats while the profile of hippocampal Crhr2 expression was affected only in EE males. Hippocampal Crh was associated with anxiety-like behavior in SD males - this did not extend to EE or CN groups, nor to females. Observations such as these are an important consideration for the validity of translational research investigating the neurocircuitry of stress resiliency, and for understanding the mechanisms of psychiatric disorders. Future work must focus on characterizing how individual environmental enhancements (e.g. novelty, social enrichment, physical activity) shape phenotypic differences, how they vary as a function of species, strain and sex, and (if warranted) how to meaningfully implement this knowledge into biomedical research designs. PMID- 29183826 TI - Developmental Ethanol-Induced Sleep Fragmentation, Behavioral Hyperactivity, Cognitive Impairment and Parvalbumin Cell Loss are Prevented by Lithium Co treatment. AB - Developmental ethanol exposure is a well-known cause of lifelong cognitive deficits, behavioral hyperactivity, emotional dysregulation, and more. In healthy adults, sleep is thought to have a critical involvement in each of these processes. Our previous work has demonstrated that some aspects of cognitive impairment in adult mice exposed at postnatal day 7 (P7) to ethanol (EtOH) correlate with slow-wave sleep (SWS) fragmentation (Wilson et al., 2016). We and others have also previously demonstrated that co-treatment with LiCl on the day of EtOH exposure prevents many of the anatomical and physiological impairments observed in adults. Here we explored cognitive function, diurnal rhythms (activity, temperature), SWS, and parvalbumin (PV) and perineuronal net (PNN) positive cell densities in adult mice that had received a single day of EtOH exposure on P7 and saline-treated littermate controls. Half of the animals also received a LiCl injection on P7. The results suggest that developmental EtOH resulted in adult behavioral hyperactivity, cognitive impairment, and reduced SWS compared to saline controls. Both of these effects were reduced by LiCl treatment on the day of EtOH exposure. Finally, developmental EtOH resulted in decreased PV/PNN-expressing cells in retrosplenial (RS) cortex and dorsal CA3 hippocampus at P90. As with sleep and behavioral activity, LiCl treatment reduced this decrease in PV expression. Together, these results further clarify the long lasting effects of developmental EtOH on adult behavior, physiology, and anatomy. Furthermore, they demonstrate the neuroprotective effects of LiCl co-treatment on this wide range of developmental EtOH's long-lasting consequences. PMID- 29183828 TI - Musical Expectations Enhance Auditory Cortical Processing in Musicians: A Magnetoencephalography Study. AB - The present study investigated the influence of musical expectations on auditory representations in musicians and non-musicians using magnetoencephalography (MEG). Neuroscientific studies have demonstrated that musical syntax is processed in the inferior frontal gyri, eliciting an early right anterior negativity (ERAN), and anatomical evidence has shown that interconnections occur between the frontal cortex and the belt and parabelt regions in the auditory cortex (AC). Therefore, we anticipated that musical expectations would mediate neural activities in the AC via an efferent pathway. To test this hypothesis, we measured the auditory-evoked fields (AEFs) of seven musicians and seven non musicians while they were listening to a five-chord progression in which the expectancy of the third chord was manipulated (highly expected, less expected, and unexpected). The results revealed that highly expected chords elicited shorter N1m (negative AEF at approximately 100 ms) and P2m (positive AEF at approximately 200 ms) latencies and larger P2m amplitudes in the AC than less expected and unexpected chords. The relations between P2m amplitudes/latencies and harmonic expectations were similar between the groups; however, musicians' results were more remarkable than those of non-musicians. These findings suggest that auditory cortical processing is enhanced by musical knowledge and long-term training in a top-down manner, which is reflected in shortened N1m and P2m latencies and enhanced P2m amplitudes in the AC. PMID- 29183829 TI - The Rodent-versus-wild Snake Paradigm as a Model for Studying Anxiety- and Panic like Behaviors: Face, Construct and Predictive Validities. AB - Using an innovative approach to study the neural bases of psychiatric disorders, this study investigated the behavioral, morphological and pharmacological bases of panic attack-induced responses in a prey-versus-coral snake paradigm. Mesocricetus auratus was chronically treated with intraperitoneal administration of the selective serotonin uptake inhibitor paroxetine or the gamma aminobutyric acid (GABA)/benzodiazepine receptor agonist alprazolam at three different doses and were then confronted with a venomous coral snake (Micrurus frontalis, Reptilia, Elapidae). The threatened rodents exhibited defensive attention, flat back approaches, defensive immobility, and escape defensive responses in the presence of the venomous snake, followed by increases in Fos protein in limbic structure neurons. Chronic administration of both paroxetine and alprazolam decreased these responses with morphological correlates between the panicolytic effect of both drugs administered at the highest dose and decreases in Fos protein-immunolabeled perikarya found in the amygdaloid complex, hypothalamus and periaqueductal gray matter columns, which are structures that make up the encephalic aversion system. These findings provide face, construct and predictive validities of this new experimental model of anxiety- and panic attack-like behavioral responses displayed by threatened prey confronted with venomous coral snakes. PMID- 29183830 TI - Improving cannulation time for extracorporeal life support in refractory cardiac arrest of presumed cardiac cause - Comparison of two percutaneous cannulation techniques in the catheterization laboratory in a center without on-site cardiovascular surgery. AB - BACKGROUND: Cardiac arrest (CA) without return of spontaneous circulation can be treated with veno-arterial extracorporeal membrane oxygenation (vaECMO) implemented surgically or percutaneously. We performed a study assessing time for vaECMO percutaneous cannulation in the catheterization laboratory. METHODS: Single-centre retrospective study in a University hospital without on-site cardiovascular surgery, including patients aged >18 receiving vaECMO for out- or in-hospital refractory CA of presumed cardiac cause between 2010 and 2016, cannulated by interventional cardiologists. Cannulation time using anatomic landmarks vessel puncture and conventional wires (first period) was compared with ultrasound guidance puncture and stiff wires (second period). Data are expressed as medians (interquartile range) and percentages. RESULTS: Forty-six patients were included, age 56 (49-62), 34 in the first period. Shockable initial rhythm occurred in 29 (63%), 36 (78%) had ischemic heart disease and 26 (57%) acute myocardial infarction (AMI). Out-of-hospital refractory CA occurred in 27 (59%) patients. Time from out-of-hospital refractory CA to admission was 100 (80-118) min. Cannulation was successful in 42 (91%) patients. Cannulation time was 14 (10 21) min, 17 (12-26) (first) and 8 (6-12) min (second period), p<0.001. Survival to discharge was 9%. In out-of-hospital versus in-hospital, time from CA to vaECMO was 120 (115-140) versus 82 (58-102) min, p=0.011, survival was 7% (two patients) versus 11% (two patients), p=0.35 respectively. All survivors had shockable initial rhythm. CONCLUSION: In these refractory CA patients with high prevalence of AMI and good feasibility of percutaneous vaECMO in the catheterization laboratory, cannulation time was shorter using ultrasound guidance and stiff wires. PMID- 29183831 TI - 'She's sort of breathing': What linguistic factors determine call-taker recognition of agonal breathing in emergency calls for cardiac arrest? AB - BACKGROUND: In emergency ambulance calls, agonal breathing remains a barrier to the recognition of out-of-hospital cardiac arrest (OHCA), initiation of cardiopulmonary resuscitation, and rapid dispatch. We aimed to explore whether the language used by callers to describe breathing had an impact on call-taker recognition of agonal breathing and hence cardiac arrest. METHODS: We analysed 176 calls of paramedic-confirmed OHCA, stratified by recognition of OHCA (89 cases recognised, 87 cases not recognised). We investigated the linguistic features of callers' response to the question "is s/he breathing?" and examined the impact on subsequent coding by call-takers. RESULTS: Among all cases (recognised and non-recognised), 64% (113/176) of callers said that the patients were breathing (yes-answers). We identified two categories of yes-answers: 56% (63/113) were plain answers, confirming that the patient was breathing ("he's breathing"); and 44% (50/113) were qualified answers, containing additional information ("yes but gasping"). Qualified yes-answers were suggestive of agonal breathing. Yet these answers were often not pursued and most (32/50) of these calls were not recognised as OHCA at dispatch. CONCLUSION: There is potential for improved recognition of agonal breathing if call-takers are trained to be alert to any qualification following a confirmation that the patient is breathing.

PMID- 29183833 TI - Uncontrolled donation programs after out-of-hospital cardiac arrest. An estimation of potential donors. AB - OBJECTIVE: To determine the number of potential deceased organ donors from out-of hospital cardiac arrest cases (OHCA) attended by public physician-led emergency medical services in Spain, based on data recorded in the nationwide Spanish OHCA Registry (OHSCAR). MATERIAL AND METHODS: We analysed OHSCAR data on deceased OHCA patients in Spain during 13 months (1/10/2013 to 31/10/2014). Variables included age, sex, estimated OHCA time, cardiopulmonary resuscitation (CPR) start time and outcome. Inclusion criteria were: age 16-60 years, witnessed OHCA, no return of spontaneous circulation (ROSC) and time interval <15min between OHCA occurrence and CPR initiation. RESULTS: Of a total 8789 cases, 3290 met the age criteria; of these, CPR was not witnessed in 745 cases. Among the remaining 2545 patients, 141 were included in uncontrolled donation after cardiac death (uDCD) programs, 902 arrived at the hospital with ROSC, 64 arrived with ongoing CPR and 15 cases were lost to follow-up. Of the remaining 1423 without ROSC, CPR initiation time was not recorded in 454 cases and 398 did not meet the time criteria <15min between OHCA and CPR initiation. Finally, 571 met all the criteria and could have been potential donors. There were significant differences in the actual donors percentage from potential donors percentage between provinces with and without donor programs (141/322=43.8% versus 0/390=0%), but there were no differences in ROSC between the two types of provinces (418/1320=31.7% versus 652/1970=33.4%). CONCLUSIONS: Many potential donors are missed in current clinical practice. uDCD programs are few and underused even in a country with high rates of organ transplantation.

AB - Dry eye disease (DED) affects millions of individuals in the United States and worldwide, and the incidence is increasing with an aging population. There is widespread agreement that the measurement of total tear osmolarity is the most reliable test, but this procedure provides only the total ionic strength and does not provide the concentration of each ionic species in tears. Here, we describe an approach to determine the individual ion concentrations in tears using modern silicone hydrogel (SiHG) contact lenses. We made pH (or H3O+, hydronium cation,/OH-, hydroxyl ion) and chloride ion (two of the important electrolytes in tear fluid) sensitive SiHG contact lenses. We attached hydrophobic C18 chains to water-soluble fluorescent probes for pH and chloride. The resulting hydrophobic ion sensitive fluorophores (H-ISF) bind strongly to SiHG lenses and could not be washed out with aqueous solutions. Both H-ISFs provide measurements which are independent of total intensity by use of wavelength-ratiometric measurements for pH or lifetime-based sensing for chloride. Our approach can be extended to fabricate a contact lens which provides measurements of the six dominant ionic species in tears. This capability will be valuable for research into the biochemical processes causing DED, which may improve the ability to diagnose the various types of DED.

AB - Pain is a significant clinical problem, and there is a need for effective pharmacotherapies with fewer adverse effects than currently available drugs (e.g., mu opioid receptor agonists). Cannabinoid receptor agonists enhance the antinociceptive effects of mu opioid receptor agonists, but it remains unclear which drugs and in what proportion will yield the most effective and safest treatments. The antinociceptive effects of the mu opioid receptor agonists etorphine and morphine alone and in combination with the cannabinoid receptor agonists Delta9-THC and CP55940 were studied in male Sprague-Dawley rats (n = 16) using a warm water tail withdrawal procedure. The ratio of opioid to cannabinoid (3:1, 1:1, and 1:3) varied for each mixture. Drugs administered alone or as pairwise mixtures of an opioid and a cannabinoid dose-dependently increased tail withdrawal latency. Mixtures with morphine produced supra-additive (CP55940) and additive (Delta9-THC) effects, whereas mixtures with etorphine and either cannabinoid were sub-additive. The interactions were not different among ratios for a particular mixture. The nature of the interaction between opioids and cannabinoids with regard to antinociceptive effects varies with the particular drugs in the mixture, which can have implications for designing combination therapies for pain. PMID- 29183836 TI - An update on vinpocetine: New discoveries and clinical implications. AB - Vinpocetine, a derivative of the alkaloid vincamine, has been clinically used in many countries for treatment of cerebrovascular disorders such as stroke and dementia for more than 30 years. Currently, vinpocetine is also available in the market as a dietary supplement to enhance cognition and memory. Due to its excellent safety profile, increasing efforts have been put into exploring the novel therapeutic effects and mechanism of actions of vinpocetine in various cell types and disease models. Recent studies have revealed a number of novel functions of vinpocetine, including anti-inflammation, antagonizing injury induced vascular remodeling and high-fat-diet-induced atherosclerosis, as well as attenuating pathological cardiac remodeling. These novel findings may facilitate the repositioning of vinpocetine for preventing or treating relevant disorders in humans. PMID- 29183837 TI - Melatonin inhibits rotenone-induced SH-SY5Y cell death via the downregulation of Dynamin-Related Protein 1 expression. AB - Previous studies have shown that melatonin can protect cells against rotenone induced cell death. Yet, the mechanism involved in this protection requires further research. In this study, we aimed to further investigate the effects of melatonin on inhibiting rotenone-induced SH-SY5Y cells and the underlying molecular mechanisms. Human neuroblastoma SH-SY5Y cells were treated with 0.3 or 1MUM rotenone for 6 or 12h. Cell viability was measured with an MTS assay, the mitochondrial membrane potential was determined with a Rhodamine 123 staining assay, and the protein expression levels of the markers of autophagy, including cytochrome C release (Cyt C), light chain 3B (LC3 B) and Dynamin-Related Protein 1 (Drp1) were analyzed by western blotting. The co-localization of Drp1 and TOM20 proteins in the mitochondria of SH-SY5Y cells was measured by immunofluorescence coupled with confocal microscopy and the overexpression of the Drp1 gene was then conducted. The viability and expression levels of Cyt C and LC3 B in rotenone and melatonin + rotenone-treated Drp1-overexpressed SH-SY5Y cells were analyzed with MTS and western blotting, respectively. We found that rotenone effectively induced SH-SY5Y cell death by causing mitochondrial dysfunction and increasing Cyt C expression. Drp1 expression and its regulation of mitochondrial translocation mediated the rotenone-induced cell death and melatonin inhibited this process. Overexpression of Drp1 protein attenuated melatonin's inhibition of rotenone-induced SH-SY5Y cell death. In conclusion, melatonin effectively inhibits rotenone-induced neuronal cell death via the regulation of Drp1 expression. PMID- 29183838 TI - Abediterol (LAS100977), an inhaled long-acting beta2-adrenoceptor agonist, has a fast association rate and long residence time at receptor. AB - This study describes the association rate and residence time of abediterol, a novel long-acting beta2-adrenoceptor agonist (LABA) in Phase II development for treatment of asthma and COPD, in comparison with indacaterol, olodaterol, vilanterol and salmeterol, for both human beta1- and beta2-adrenoceptors. Abediterol association and dissociation rates were monitored directly by using its tritiated form. Moreover, association was determined indirectly using experimental Ki and koff obtained from assays performed with unlabelled compound. Dissociation was also studied indirectly by measuring the association rate of 3H CGP12177 to beta adrenoceptors previously occupied by unlabelled compounds. Abediterol shows a fast association for the beta2-adrenoceptor (kon 1.4 * 107 +/- 1.8 * 106M-1min-1) while its dissociation rate is between 30 and 64 times slower than that of the reference LABA compounds tested, with a residence time of 91.3 +/- 13.3min (measured directly) and 185.5 +/- 7.5min (measured indirectly). Abediterol shows kinetic selectivity for the beta2- over the beta1-adrenoceptor, with a dissociation rate from the beta1-adrenoceptor similar to the other LABA compounds tested. In conclusion, abediterol is a potent LABA with a fast association rate and a long residence time at beta2-adrenoceptors. These data are in agreement with the onset and duration of action of abediterol shown in humans. PMID- 29183839 TI - The role of ethyl acrylate induced GSH depletion in the rodent forestomach and its impact on MTD and in vivo genotoxicity in developing an adverse outcome pathway (AOP). AB - Adverse outcome pathways (AOP) and mode of action (MOA) frameworks help evaluate the toxicity findings of animal studies and their relevance to humans. To effectively use these tools to improve hazard identification and risk assessments for ethyl acrylate (EA), knowledge gaps in metabolism and genotoxicity were identified and addressed. For EA, hypothesized early key events relate to its irritation potential: concentration dependent irritation and cytotoxicity, progressing to regenerative proliferation and forestomach carcinogenicity after repeated oral bolus application in rodents. The current research quantitated glutathione (GSH) depletion to assess a kinetically-derived maximum tolerated dose (MTD) in the target tissue and used this information to conduct an in vivo genotoxicity study using current methods. In the mouse forestomach, gavage doses of EA caused GSH depletion to 47% of control at 20 mg/kg and 28% at 100 mg/kg. Cellular redox changes and histopathology support saturation of metabolism and an MTD of ~50 mg/kg. No increases in point mutations or deletions occurred in the stomach or liver following a 28 day treatment of gpt delta transgenic mice at gavage doses up to 50 mg/kg/day. These results provide valuable information for evaluating AOP molecular initiating events or MOA key events for EA and other GSH depleting materials. PMID- 29183840 TI - Comparative expression analyses of bone morphogenetic protein 4 (BMP4) expressions in muscles of tilapia and common carp indicate that BMP4 plays a role in the intermuscular bone distribution in a dose-dependent manner. AB - Intermuscular bones in fish negatively influence both meet processing and attractiveness to consumers. Tilapia (Oreochromis niloticus) and common carp (Cyprinus carpio) are both major farmed fish species globally, but whereas the former does not possess intermuscular bones, the latter does. Therefore, these two species might present a good model to study the genetic control of distribution of intermuscular bones in fish. Bone morphogenetic protein 4 (BMP4) gene is associated with tissue ossification and bone regeneration in mammals, but in fish its role in ossification remains understudied. To study the relationship between BMP4 and bone distribution in fish, we determined the expression of BMP4 in muscle tissues of common carp and tilapia on transcriptional and translational levels. As the gene has been merely predicted in silico from the genome of common carp, we have cloned and characterized it. The gene (GenBank: HQ446455) contains one intron and two exons, which encode a 400-amino acid protein with high homology to other known BMP4 protein sequences. Phylogenetic analysis showed that common carp clustered within the Cypriniformes clade (zebrafish was the closest ortholog) and tilapia within the Percomorpha clade. Using microCT scanning, we confirmed that intermuscular bones could be observed only in common carp (none in tilapia), but only in dorsal and caudal muscles (none in the ventral muscle). Expression levels of BMP4 in the muscles of common carp were in agreement with this observation both on transcriptional (qPCR) and translational (immunohistochemistry) level: higher in dorsal and caudal muscles, and lower in the ventral muscle. In tilapia, expression of BMP4 gene was also detectable in all three muscles, but expression levels in all three muscles were comparable to the one observed in the ventral muscle of carp, i.e., very low. Therefore, among the six studied muscles, the expression of BMP4 was high only in the two that possess intermuscular bones: dorsal and caudal muscles of common carp. The results of this study suggest that BMP4 is likely to play a key role in the determination of intermuscular bone distribution in fish in a dose-dependent manner. PMID- 29183841 TI - Prevalence and genetic diversity of human diarrheagenic Escherichia coli isolates by multilocus sequence typing. AB - BACKGROUND: The population structure of human diarrheagenic Escherichia coli (DEC) isolates derived from worldwide collections remains undefined. METHODS: A total of 1196 clinical isolates were obtained from a multilocus sequence typing (MLST) database. Genetic diversity analysis, MLST analysis, and phylogenetic analysis combined with different pathotypes were performed through a variety of calculation software applications. RESULTS: All isolates were categorized as one of 579 different sequence types (STs). The eBURST algorithm resolved these 579 STs into 27 clonal complexes (CCs), 37 concatemers, and 210 singletons, revealing a high level of genetic diversity in the population structure of DEC. CC10 was the most prevalent CC, comprising 276 (23.08%, 276/1196) isolates with 85 (14.68%, 85/579) STs widely distributed in 20 countries. The population structure of five common pathotypes was highly diversified, and isolates with the same ST or CC were heterogeneous for different pathotypes. Sequence variations were more abundant in fumC and gyrB than in the other five genes, and these exhibited the highest degree of nucleotide diversity (0.03886 and 0.03075, respectively) and the greatest number of polymorphic nucleotide sites (137 and 139, respectively). The dN/dS ratios of seven analyzed loci varied from 0.0083 (recA) to 0.0434 (purA), and the ratio for the concatenated sequence was 0.2518, revealing the effects of purifying selection on housekeeping genes during the evolutionary process. Significant allele linkage disequilibrium was detected when the standardized index of association (ISA) was calculated both for the entire collection of isolates (0.3174, p<0.001) and for the 579 STs (0.1475, p<0.001). CONCLUSIONS: This study facilitated a comprehensive understanding of the genetic diversity of human DEC distributed across the global population. The results provide genetic evidence that will allow us to uncover the microevolutionary relationships among different pathogenic isolates of DEC. PMID- 29183842 TI - Systematic review of seroepidemiological studies on Japanese encephalitis in the Republic of Korea. AB - BACKGROUND: Countries with strong vaccination programmes, including the Republic of Korea, have experienced changes in the epidemiology of Japanese encephalitis (JE), with an increase in cases seen among adults. However, the reasons for this increase are not clearly understood. This study describes the change in age specific JE virus (JEV) seroprevalence over time in Korea, with a view to understanding this transition. METHODS: A search of Embase, MEDLINE, PubMed, KoreaMed, Korea Education and Research Information Service, National Library of Korea, and the Seoul National University Medical Library was conducted using the keywords 'Japanese encephalitis' combined with 'Korea', 'seroprevalence', 'seropositivity', 'seroepidemiology', 'serosurvey', 'immunity', and 'antibody'. RESULTS: Eighteen studies published between 1946 and 2012 were retrieved. In 1946, seropositivity was 51% in the 1-10 years age group, 79% in those aged 11-20 years, and 94% in those >=61 years of age. In the 1970s, seropositivity in children and adolescents was low (10-59%); seropositivity in this group increased to 90-92% in 1984-1985, and increased further to 98% in 2012. Seropositivity among adults aged 41-50 years and 51-60 years in the 2010s ranged between 83.1% and 97.9% and between 77.5% and 98.3%, respectively. CONCLUSIONS: The implementation of the universal JE vaccination programme in the 1980s has increased the seroprevalence of JEV in Korea, especially in children who are targeted for vaccination. PMID- 29183843 TI - The Montreal Cognitive Assessment-Basic (MoCA-B) is not a reliable screening tool for cognitive decline in HIV patients receiving combination antiretroviral therapy in rural South Africa. AB - BACKGROUND: HIV-associated neurocognitive disorders (HAND) are frequently occurring comorbidities in HIV-positive patients, diagnosed by means of a neuropsychological assessment (NPA). Due to the magnitude of the HIV-positive population in Sub-Saharan Africa, easy-to-use cognitive screening tools are essential. METHODS: This was a cross-sectional clinical trial involving 44 HIV positive patients (on stable cART) and 73 HIV-negative controls completing an NPA, the International HIV Dementia Scale (IHDS), and a culturally appropriate cognitive screening tool, the Montreal Cognitive Assessment-Basic (MoCA-B). HAND were diagnosed by calculating Z-scores using internationally published normative data on NPA, as well as by using data from the HIV-negative group to validate the MoCA-B. RESULTS: One hundred and seventeen patients were included (25% male, median age 35 years, median 11 years of education). A moderate correlation was found between the MoCA-B and NPA total Z-score (Pearson's r=0.36, p=0.02). Area under the curve (AUC) values for MoCA-B and IHDS were 0.59 and 0.70, respectively. The prevalence of HAND in HIV-positive patients was 66% when calculating Z-scores using published normative data versus 48% when using the data from the present HIV-negative cohort. CONCLUSION: The MoCA-B appeared not to be a valid screening tool for HAND in this setting. The prevalence of HAND in this setting is high, but appeared overestimated when using published norms. PMID- 29183844 TI - Original paper: Efficacy and safety analysis of insulin degludec/insulin aspart compared with biphasic insulin aspart 30: A phase 3, multicentre, international, open-label, randomised, treat-to-target trial in patients with type 2 diabetes fasting during Ramadan. AB - AIMS: To compare the efficacy and safety of insulin degludec/insulin aspart (IDegAsp) and biphasic insulin aspart 30 (BIAsp 30) before, during and after Ramadan in patients with type 2 diabetes mellitus (T2DM) who fasted during Ramadan. METHODS: In this multinational, randomised, treat-to-target trial, patients with T2DM who intended to fast and were on basal, pre- or self-mixed insulin +/- oral antidiabetic drugs for >=90 days were randomised (1:1) to IDegAsp twice daily (BID) or BIAsp 30 BID. Treatment period included pre-Ramadan treatment initiation (with insulin titration for 8-20 weeks), Ramadan (4 weeks) and post-Ramadan (4 weeks). Insulin doses were reduced by 30-50% for the pre-dawn meal (suhur) on the first day of Ramadan, and readjusted to the pre-Ramadan levels at the end of Ramadan. Hypoglycaemia was analysed as overall (severe or plasma glucose <3.1 mmol/L [56 mg/dL]), nocturnal (00:01-05:59) or severe (requiring assistance of another person). RESULTS: During the treatment period, IDegAsp (n = 131) had significantly lower overall and nocturnal hypoglycaemia rates with similar glycaemic efficacy, versus BIAsp 30 (n = 132). During Ramadan, despite achieving significantly lower pre-iftar (meal at sunset) self-measured plasma glucose (estimated treatment difference: -0.54 mmol/L [-1.02; -0.07]95% CI, p = .0247; post hoc) with similar overall glycaemic efficacy, IDegAsp showed significantly lower overall and nocturnal hypoglycaemia rates versus BIAsp 30. CONCLUSIONS: IDegAsp is a suitable therapeutic agent for patients who need insulin for sustained glucose control before, during and after Ramadan fasting, with a significantly lower risk of hypoglycaemia, versus BIAsp 30, an existing premixed insulin analogue. PMID- 29183846 TI - Do we still need ICDs if we have ARNi? PMID- 29183845 TI - Comparison of adiposity indicators associated with fasting-state insulinemia, triglyceridemia, and related risk biomarkers in a nationally representative, adult population. AB - AIMS: We hypothesized that height-corrected abdominal size (supine sagittal abdominal diameter/height ratio [SADHtR] or waist circumference/height ratio [WHtR]) would associate more strongly than body mass index (BMI, weight/height2) with levels of fasting insulin, triglycerides, and three derived biomarkers of insulin resistance. METHODS: Anthropometry, including SAD by caliper, was collected on 4398 adults in the 2011-2014 National Health and Nutrition Examination Survey. For comparison purposes, each adiposity indicator was scaled to its population-based, sex-specific, interquartile range (IQR). For each biomarker we created four outcome groups based on equal-sized populations with ascending values. Multivariable polytomous logistic regression modeled the relationships between the adiposity indicators and each biomarker. RESULTS: Highest-group insulin was associated with a one-IQR increment of BMI (RR 4.3 [95% CI 3.9-4.9]), but more strongly with a one-IQR increment of SADHtR (RR 5.7 [5.0 6.6]). For highest-group HOMA-IR the RR for BMI (4.2 [3.7-4.6]) was less than that of SADHtR (6.0 [5.1-7.0]). Similarly, RRs for BMI were smaller than those for SADHtR applying to highest-group triglycerides (RR 1.6 vs 2.1), triglycerides/HDL-cholesterol (RR 1.9 vs 2.4) and TyG index (RR 1.7 vs 2.2) (all p < .001). The RRs for WHtR were consistently between those for SADHtR and BMI. The top 25% of insulin resistance among US adults was estimated to lie above adiposity thresholds of 0.140 for SADHtR, 0.606 for WHtR, or 29.6 kg/m2 for BMI. CONCLUSIONS: Relative abdominal size rather than relative weight may better define adiposity associated with homeostatic insulin resistance. These population based, cross-sectional findings could improve anthropometric prediction of cardiometabolic risk. PMID- 29183847 TI - Breath figures in tissue engineering and drug delivery: State-of-the-art and future perspectives. AB - : The breath figure (BF) method is an easy, low-cost method to prepare films with a highly organized honeycomb-like porous surface. The particular surface topography and porous nature of these materials makes them valuable substrates for studying the complex effects of topography on cell fate, and to produce biomimetic materials with high performance in tissue engineering. Numerous researchers over the last two decades have studied the effects of the honeycomb topography on a variety of primary and immortalized cell lines, and drew important conclusions that can be translated to the construction of optimal biomaterials for cell culture. The literature also encouragingly shows the potential of honeycomb films to induce differentiation of stem cells down a specific lineage without the need for biochemical stimuli. Here, we review the main studies where BF honeycomb films are used as substrates for tissue engineering applications. Furthermore, we highlight the numerous advantages of the porous nature of the films, such as the enhanced, spatially controlled adsorption of proteins, the topographical cues influencing cellular behavior, and the enhanced permeability which is essential both in vitro and in vivo. Finally, this review highlights the elegant use of honeycomb films as drug-eluting biomaterials or as reservoirs for distinct drug delivery systems. STATEMENT OF SIGNIFICANCE: Combining biocompatible surfaces and 3D nano/microscale topographies, such as pores or grooves, is an effective strategy for manufacturing tissue engineering scaffolds. The breath figure (BF) method is an easy technique to prepare cell culture substrates with an organized, honeycomb like porous surface. These surface features make these scaffolds valuable for studying how the cells interact with the biomaterials. Their unique surface topography can also resemble the natural environment of the tissues in the human body. For that reason, numerous studies, using different cell types, have shown that honeycomb films can constitute high performance substrates for cell culture. Here, we review those studies, we highlight the advantages of honeycomb films in tissue engineering and we discuss their potential as unique drug-eluting systems. PMID- 29183848 TI - Combinational siRNA delivery using hyaluronic acid modified amphiphilic polyplexes against cell cycle and phosphatase proteins to inhibit growth and migration of triple-negative breast cancer cells. AB - : Triple-negative breast cancer is an aggressive form of breast cancer with few therapeutic options if it recurs after adjuvant chemotherapy. RNA interference could be an alternative therapy for metastatic breast cancer, where small interfering RNA (siRNA) can silence the expression of aberrant genes critical for growth and migration of malignant cells. Here, we formulated a siRNA delivery system using lipid-substituted polyethylenimine (PEI) and hyaluronic acid (HA), and characterized the size, zeta-potential and cellular uptake of the nanoparticulate delivery system. Higher cellular uptake of siRNA by the tailored PEI/HA formulation suggested better interaction of complexes with breast cancer cells due to improved physicochemical characteristics of carrier and HA-binding CD44 receptors. The siRNAs against specific phosphatases that inhibited migration of MDA-MB-231 cells were then identified using library screen against 267 protein tyrosine phosphatases, and siRNAs to inhibit cell migration were further validated. We then assessed the combinational delivery of a siRNA against CDC20 to decrease cell growth and a siRNA against several phosphatases shown to decrease migration of breast cancer cells. Combinational siRNA therapy against CDC20 and identified phosphatases PPP1R7, PTPN1, PTPN22, LHPP, PPP1R12A and DUPD1 successfully inhibited cell growth and migration, respectively, without interfering the functional effect of the co-delivered siRNA. The identified phosphatases could serve as potential targets to inhibit migration of highly aggressive metastatic breast cancer cells. Combinational siRNA delivery against cell cycle and phosphatases could be a promising strategy to inhibit both growth and migration of metastatic breast cancer cells, and potentially other types of metastatic cancer. STATEMENT OF SIGNIFICANCE: The manuscript investigated the efficacy of a tailored polymeric siRNA delivery system formulation as well as combinational siRNA therapy in metastatic breast cancer cells to inhibit malignant cell growth and migration. The siRNA delivery was undertaken by non viral means with PEI/HA. We identified six phosphatases that could be critical targets to inhibit migration of highly aggressive metastatic breast cancer cells. We further report on specifically targeting cell cycle and phosphatase proteins to decrease both malignant cell growth and migration simultaneously. Clinical gene therapy against metastatic breast cancer with effective and safe delivery systems is urgently needed to realize the potential of molecular medicine in this deadly disease and our studies in this manuscript is intended to facilitate this endeavor. PMID- 29183849 TI - A sterilization method for decellularized xenogeneic cardiovascular scaffolds. AB - : Decellularized xenogeneic scaffolds have shown promise to be employed as compatible and functional cardiovascular biomaterials. However, one of the main barriers to their clinical exploitation is the lack of appropriate sterilization procedures. This study investigated the efficiency of a two-step sterilization method, antibiotics/antimycotic (AA) cocktail and peracetic acid (PAA), on porcine and bovine decellularized pericardium. In order to assess the efficiency of the method, a sterilization assessment protocol was specifically designed, comprising: i) controlled contamination with a known amount of bacteria; ii) sterility test; iii) identification of contaminants through MALDI-TOF (Matrix Assisted Laser Desorption/Ionization Time-of-Flight) mass spectrometry and iv) quantification by the Most Probable Number (MPN) method. This sterilization assessment protocol proved to be a successful tool to monitor and optimize the proposed sterilization method. The treatment with AA + PAA method provided sterile scaffolds while preserving the structural integrity and biocompatibility of the decellularized porcine and bovine tissues. However, surface properties and cellular adhesion resulted slightly impaired on porcine pericardium. This work developed a sterilization method suitable for decellularized pericardial scaffolds that could be adopted for in vivo tissue engineering. Together with the proposed sterilization assessment protocol, this decontamination method will foster the clinical translation of decellularized xenogeneic substitutes. STATEMENT OF SIGNIFICANCE: Clinical application of functional and compatible xenogeneic decellularized scaffolds has been delayed due to the lack of appropriate sterilization methodologies. In this study, it was investigated an effective sterilization method optimized for porcine and bovine decellularized pericardia, based on the use of antibiotics/antimycotics followed by peracetic acid treatment. This treatment effectively sterilizes both species scaffolds, proves to maintain tissue overall structure and components, preserves biocompatibility and biomechanical properties. Furthermore, it was also developed a sterilization assessment protocol used to monitor and validate the previous method, consisting in three main parts: i) controlled contamination; ii) sterility test, and iii) identification and quantification of contaminants. Both methodologies were optimized for the tissues in study but can be applied to other scaffolds and accelerate their clinical translation. PMID- 29183850 TI - Effects of nanofeatures induced by severe shot peening (SSP) on mechanical, corrosion and cytocompatibility properties of magnesium alloy AZ31. AB - : The application of biodegradable magnesium-based materials in the biomedical field is highly restricted by their low fatigue strength and high corrosion rate in biological environments. Herein, we treated the surface of a biocompatible magnesium alloy AZ31 by severe shot peening in order to evaluate the potential of surface grain refinement to enhance this alloy's functionality in a biological environment. The AZ31 samples were studied in terms of micro/nanostructural, mechanical, and chemical characteristics in addition to cytocompatibility properties. The evolution of surface grain structure and surface morphology were investigated using optical, scanning and transmission electron microscopy. Surface roughness, wettability, and chemical composition, as well as in depth microhardness and residual stress distribution, fatigue behaviour and corrosion resistance were investigated. Cytocompatibility tests with osteoblasts (bone forming cells) were performed using sample extracts. The results revealed for the first time that severe shot peening can significantly enhance mechanical properties of AZ31 without causing adverse effects on the growth of surrounding osteoblasts. The corrosion behavior, on the other hand, was not improved; nevertheless, removing the rough surface layer with a high density of crystallographic lattice defects, without removing the entire nanocrystallized layer, provided a good potential for improving corrosion characteristics after severe shot peening and thus, this method should be studied for a wide range of orthopedic applications in which biodegradable magnesium is used. STATEMENT OF SIGNIFICANCE: A major challenge for most commonly used metals for bio-implants is their non-biodegradability that necessitates revision surgery for implant retrieval when used as fixation plates, screws, etc. Magnesium is reported among the most biocompatible metals that resorb over time without adverse tissue reactions and is indispensable for many biochemical processes in human body. However, fast and uncontrolled degradation of magnesium alloys in the physiological environment in addition to their inadequate mechanical properties especially under repeated loading have limited their application in the biomedical field. The present study providesdata on the effect of a relatively simple surface nanocrystallziation method with high potential to tailor the mechanical and chemical behavior of magnesium based material while maintaining its cytocompatibility. PMID- 29183851 TI - A retrospective study of human cystic echinococcosis in Basrah province, Iraq. AB - Human cystic echinococcosis (CE) is a parasitic zoonosis with serious clinical burden and constitutes a challenge to public health in endemic areas worldwide. We performed a retrospective study to investigate the occurrence of CE in patients at six hospitals in Basrah province, Iraq. In the current study setting, data retrieval and validation of the quality of hospital records was very challenging considering the difficult situation Iraq is unfortunately facing. Hospitalization records were reviewed from January 2005 to December 2015. A total of 748 cases of human with CE were diagnosed and operated in Basrah hospitals, equivalent to an annual clinical incidence of approximately 4.5 cases per 100 000 people. Hospital records show that, cystic echinococcosis affected more females (61.2%) than males (38.8%). Descriptive review of recorded CE cases in the surveyed hospitals revealed that more cases were reported in the age group of 21 30 years than in the other age groups. Based on the reviewed recorded clinical reports, cysts were mainly found in the liver (46.3%) and lungs (28.1%) of the patients. Hospital reports demonstrate that females had more hepatic cysts (63.9%) than males (36.1%). This study found that CE continues to pose a threat to public health in Basrah, and there is a need for more epidemiological investigations of CE in humans in order to determine risk factors and the economic impact of the disease in this province of Iraq. PMID- 29183852 TI - Identification of an area predominantly endemic for childhood and adolescent visceral leishmaniasis in central Sudan. AB - Although widely spread throughout Sudan, visceral leishmaniasis (VL) is predominantly endemic in the Gedaref, southern Blue-Nile, and Umrimta areas located in the eastern, southern, and central regions, respectively. Regardless of form (endemic or epidemic), VL occurrence follows similar patterns as all ages and both sexes are affected. From January 2005 to May 2016, we received a total of 563 patients with high suspicion for VL from various endemic areas; 159 were children and adolescents (0.5-18 years) from Umrimta (central Sudan). A significant observation during this 11-year period of uninterrupted monitoring using a standard liquid direct agglutination test (LQ-DAT) version was the exclusive VL occurrence (100%) in the child and adolescent populations of Umrimta when compared with other endemic areas (27.3%-48.0%). Among 12 child and adolescent suspects who initially tested marginal in the standard LQ-DAT, 6 scored unequivocally positive readings both in an improved LQ-DAT version (based on an autochthonous Leishmania donovani strain) and rK28 VL reference test. None of the 4 (2.5%) VL adult suspects (>=19years) referred had positive outcomes in the improved LQ-DAT version or the VL reference freeze-dried direct agglutination and rK28 tests. Further incorporation of antigens derived from autochthonous L. donovani strains from Umrimta (central Sudan) or Gedaref (eastern Sudan) in LQ DAT significantly increased the agglutination titer levels in the respective VL homologous sera (p=0.0263 T=505 and p=0.2814T=219), suggesting possible antigenic variation within the predominant Sudanese L. donovani complex. Additional research is required to determine characteristics other than the serologically based ones reported for the L. donovani strain involved. PMID- 29183853 TI - Toxicity of Usnic Acid from Cladonia substellata (Lichen) to embryos and adults of Biomphalaria glabrata. AB - This study reports the molluscicidal activity of usnic acid isolated from Cladonia substellata Vanio (lichen) on embryos at various stages of development and in adult mollusks of Biomphalaria glabrata. The toxicity of usnic acid was also evaluated through Artemia salina larvae mortality. Usnic acid was extracted with diethyl ether, isolated, purified, and its structure confirmed by analyzing the spectra of proton nuclear magnetic resonance. LC90 for 24 h of exposure were 1.62, 4.45, 5.36, and 4.49 MUg mL-1 for blastula, gastrula, trocophore, and veliger embryonic stages, respectively, and 3.45 MUg mL-1 for adult snails; LC50 of usnic acid against A. salina was 2.46 MUg mL-1. LC90 assessed 7 days after exposure was 2.56 MUg mL-1 for adult mollusks. In conclusion, these findings demonstrate that under laboratory conditions usnic acid has teratogenic and molluscicide potential to control the aquatic snail B. glabrata and may prove to be a promising candidate in the search for new molluscicide agents, but further detailed studies on its molluscicidal effect and possible environmental effects are needed.

AB - In the spatial structure of tyrosine phenol-lyase, the Ser51 residue is located in the active site of the enzyme. The replacement of Ser51 with Ala by site directed mutagenesis led to a decrease of the kcat/Km parameter for reactions with l-tyrosine and 3-fluoro-l-tyrosine by three orders of magnitude, compared to wild type enzyme. For the elimination reactions of S-alkylcysteines, the values of kcat/Km decreased by an average of two orders of magnitude. The results of spectral studies of the mutant enzyme gave evidence for a considerable change of the chiral properties of the active site as a result of the replacement. Fast kinetic studies for the complexes of the mutant form with competitive inhibitors allowed us to conclude that the Ser51 residue interacts with the side chain amino group of Lys257 at the stage of C-alpha-proton abstraction. This interaction ensures the correct orientation of the side chain of Lys257 accepting the C-alpha proton of the external aldimine and stabilizes its ammonium form. Also, it is probable that Ser51 takes part in formation of a chain of hydrogen bonds which is necessary to perform the transfer of the C-alpha-proton to the C-4'-position of the leaving phenol group in the reaction with the natural substrate.

AB - Fused deposition modelling (FDM) 3D printing (3DP) is a revolutionary technology with the potential to transform drug product design in both the pre-clinical and clinical arena. The objective of this pilot study was to explore the intestinal behaviour of four different polymer-based devices fabricated using FDM 3DP technology in rats. Small capsular devices of 8.6 mm in length and 2.65 mm in diameter were printed from polyvinyl alcohol-polyethylene glycol graft-copolymer (PVA-PEG copolymer, Kollicoat IR), hydroxypropylcellulose (HPC, Klucel), ethylcellulose (EC, Aqualon N7) and hypromellose acetate succinate (HPMCAS, Aquasolve-LG). A smaller sized device, 3.2 mm in length and 2.65 mm in diameter, was also prepared with HPMCAS to evaluate the cut off size of gastric emptying of solid formulations in rats. The devices were radiolabelled with Fluorodeoxyglucose (18F-FDG) and small animal positron emission tomography/computed tomography (microPET/CT) was used to track the movement and disintegration of the fabricated devices in the rats. The PVA-PEG copolymer and HPC devices disintegrated after 60min following oral administration. The EC structures did not disintegrate in the gastrointestinal tracts of the rats, whereas the HPMCAS-based systems disintegrated after 420 min. Interestingly, it was noted that the devices which remained intact over the course of the study had not emptied from the stomach of the rats. This was also the case with the smaller sized device. In summary, we report for the first time, the use of a microPET/CT imaging technique to evaluate the in vivo behaviour of 3D printed formulations. The manipulation of the 3D printed device design could be used to fabricate dosage forms of varying sizes and geometries with better gastric emptying characteristics suitable for rodent administration. The increased understanding of the capabilities of 3DP in dosage form design could, henceforth, accelerate pre-clinical testing of new drug candidates in animal models. PMID- 29183856 TI - Mesoporous systems for poorly soluble drugs - recent trends. AB - When poor aqueous solubility of active pharmaceutical ingredients is encountered during a drug formulation process, the toolbox typically utilized contains pharmaceutical salts, co-crystals, solid dispersions, cyclodextrins, lipids, liposomes and nanocrystals etc. Especially in the pharmaceutical industry, the option which confers the greatest benefit with the lowest risk is usually chosen. Several factors affect the final decision, but new technologies should also be considered especially if they can address several issues at the same time. Mesoporous inorganic systems are emerging technologies which can be utilized for improving the dissolution of poorly soluble drugs. The number of the scientific papers in this field is steadily increasing and the focus of the studies is moving away from in vitro to in vivo experiments with the first human trial already completed. Meanwhile, several start-up companies focusing on mesoporous carriers have been established. Therefore, it is conceivable that the first commercial products will find their way to pharmacies during the next 5-10 years. The present review surveys recent progress in research on mesoporous materials as carriers of poorly soluble drugs. We will concentrate on the research published since our previous review published in 2012 [10.1016/j.ijpharm.2012.09.008] up to the present day. PMID- 29183857 TI - Understanding the generation and maintenance of supersaturation during the dissolution of amorphous solid dispersions using modulated DSC and 1H NMR. AB - In this study, the dissolution behaviour of dipyridamole (DPM) and cinnarizine (CNZ) spray-dried amorphous solid dispersions (ASDs) using polyvinyl pyrrolidone (PVP) and polyacrylic acid (PAA) as a carrier matrix were evaluated and compared. The drug concentrations achieved from the dissolution of PVP and PAA solid dispersions were significantly greater than the equilibrium solubility of crystalline DPM and CNZ in phosphate buffer pH 6.8 (PBS 6.8). The maximum drug concentration achieved by dissolution of PVP and PAA solid dispersions did not exceed the theoretically calculated apparent solubility of amorphous DPM and CNZ. However, the degree of supersaturation of DPM and CNZ increased considerably as the polymer weight fraction within the solid dispersion increased. In addition, the supersaturation profile of DPM and CNZ were studied in the presence and absence of the polymers. PAA was found to maintain a higher level of supersaturation compared to PVP. The enhanced drug solution concentration following dissolution of ASDs can be attributed to the reduced crystal growth rates of DPM and CNZ at an equivalent supersaturation. We have also shown that, for drugs having high crystallization tendency and weak drug-polymer interaction, the feasible way to increase dissolution might be increase the polymer weight fraction in the ASD. Solution 1H NMR spectra were used to understand dissolution mechanism and to identify drug-polymer interaction. The change in electron densities of proton attached to different groups in DPM and CNZ suggested drug polymer interaction in solution. The relative intensities of peak shift and nature of interaction between drug and polymer in different systems are different. These different effects suggest that DPM and CNZ interacts in a different way with PVP and PAA in solution which goes some way towards explaining the different polymeric effect, particularly in terms of inhibition of drug recrystallization and dissolution of DPM and CNZ ASDs. These results established that the different drug/polymer interactions in the solid state and in solution give rise to the variation in dissolution profile observed for different systems. PMID- 29183858 TI - QR encoded smart oral dosage forms by inkjet printing. AB - The use of inkjet printing (IJP) technology enables the flexible manufacturing of personalized medicine with the doses tailored for each patient. In this study we demonstrate, for the first time, the applicability of IJP in the production of edible dosage forms in the pattern of a quick response (QR) code. This printed pattern contains the drug itself and encoded information relevant to the patient and/or healthcare professionals. IJP of the active pharmaceutical ingredient (API)-containing ink in the pattern of QR code was performed onto a newly developed porous and flexible, but mechanically stable substrate with a good absorption capacity. The printing did not affect the mechanical properties of the substrate. The actual drug content of the printed dosage forms was in accordance with the encoded drug content. The QR encoded dosage forms had a good print definition without significant edge bleeding. They were readable by a smartphone even after storage in harsh conditions. This approach of efficient data incorporation and data storage combined with the use of smart devices can lead to safer and more patient-friendly drug products in the future. PMID- 29183859 TI - Risk of autism spectrum disorder in children born to mothers with systemic lupus erythematosus and rheumatoid arthritis in Taiwan. AB - OBJECTIVES: To determine whether offspring of Taiwanese mothers with systemic lupus erythematosus or rheumatoid arthritis have a higher risk of autism spectrum disorder. METHODS: Using the National Health Insurance database and National Birth Registry, we identified a cohort of all live births in Taiwan between 2001 and 2012. Children born to mothers with systemic lupus erythematosus or rheumatoid arthritis were identified and matched with up to 8 controls by maternal age, 1-minute Apgar score, 5-minute Apgar score, mode of delivery, sex of the child, gestational age, birth weight and place of residence. Marginal Cox proportional hazard models were used to estimate relative risk (RR) with 95% confidence intervals (CI) for ASD in offspring. RESULTS: Of 1,893,244 newborns, 0.08% (n=1594) were born to systemic lupus erythematosus mothers, and 0.04% (n=673) were born to rheumatoid arthritis mothers. Overall, 5 of 673 (0.74%) offspring of rheumatoid arthritis mothers, 7 of 1594 (0.44%) offspring of systemic lupus erythematosus mothers and 10,631 of 1,893,244 (0.56%) offspring of all mothers developed autism spectrum disorder. Autism spectrum disorder incidence (per 100,000 person-years) was 140.39 (95% CI, 45.58-327.62) for the rheumatoid arthritis group and 76.19 (95% CI, 30.63-156.97) for the systemic lupus erythematosus group. Autism spectrum disorder risk was not significantly higher for children born to mothers with rheumatoid arthritis (HR, 1.42; 95% CI, 0.60-3.40) or systemic lupus erythematosus (HR, 0.76; 95% CI, 0.36-1.59). CONCLUSIONS: Children born to women with systemic lupus erythematosus or rheumatoid arthritis do not have a higher risk of autism spectrum disorder. PMID- 29183860 TI - Anti-citrullinated peptides antibodies in systemic sclerosis: Meta-analysis of frequency and meaning. AB - OBJECTIVES: Diagnosis of systemic sclerosis (SSc) is partially determined by the presence of specific autoantibodies often associated with specific clinical features. Recent studies report the presence of ACPA in SSc. We aimed to evaluate the prevalence of ACPA in SSc and to assess their influence on clinical presentation of SSc. METHODS: A systematic literature search was performed using PubMed and Cochrane databases' publications between 1999 and March 2017. Search terms were: "systemic sclerosis [MeSH] AND (ACPA OR anti-CCP OR rheumatoid factor OR cohort OR value diagnostic)". In a first step, we selected cohorts with >50 SSc patients with ACPA identification, for ACPA frequency determination. In a second step, we included studies that analysed clinical profiles according to ACPA status. Meta-analyses were performed when at least two studies were available. RESULTS: First, we identified 13 observational studies with a total of 1231 SSc patients. The mean prevalence of ACPA in SSc was 9.2%. Secondly, we identified nine studies reporting clinical aspects according to ACPA status. Our meta-analyses showed a significant association between ACPA positivity and the presence of arthritis (odds ratio (OR)=22.48 [10.71-47.21]), joint erosions seen on X-rays (OR=14.79 [6.38-34.28]), pulmonary fibrosis (OR=2.75 [1.21-6.24]), oesophagus involvement (OR=2.72 [1.05-7.07]), and diffuse skin involvement (OR=2.21 [1.21-4.03]). CONCLUSIONS: The prevalence of ACPA in scleroderma is 9.2%. Our meta-analysis shows an increased risk for erosive arthritis, pulmonary fibrosis, oesophagus involvement and diffuse skin involvement, in patients with ACPA-positive SSc. ACPA should be systematically included in SSc assessment. PMID- 29183861 TI - Bilateral striopallidodentate calcinosis associated with Sjogren's syndrome and IgDlambda monoclonal gammopathy of undetermined significance. AB - We presented the first case of bilateral striopallidodentate calcinosis secondary to Sjogren's syndrome. Further consideration should be given to the association between Sjogren's syndrome and bilateral striopallidodentate calcinosis, because Sjogren's syndrome is latent, but more frequent than other autoimmune diseases. PMID- 29183863 TI - A new strategy for battling bacterial resistance: Turning potent, non-selective and potentially non-resistance-inducing biocides into selective ones. AB - Antibiotic alternatives are in great need for combating antibiotic resistance. Selective delivery of a potent non-selective non-resistance-inducing biocide (C17) to MRSA was achieved by encapsulating it in solid lipid nanoparticles (SLNs) conjugated with a MRSA-specific antibody (termed as "Ab"). The C17-loaded Ab-conjugated SLNs (C17-SLN-Ab) demonstrated significantly better antimicrobial activity than its antibody free counterpart (C17-loaded SLN) and C17-loaded SLN with a non-specific IgG antibody. In a new MRSA/fibroblast co-culture assay, C17 SLN-Ab showed selective toxicity toward MRSA than fibroblast cells. C17-SLN-Ab possesses double selectivity, exhibiting higher toxicity to MRSA than to Pseudomonas aeruginosa. This same strategy was used to successfully increase C17's selectivity against E. coli K12 by switching the conjugated anti-MRSA antibody to an anti-E. coli antibody, demonstrating versatility of this new strategy. This proof-of-concept research can be extended to other non-selective antimicrobials, against which bacterial resistance is unlikely to develop, to generate a new group of promising antibiotic alternatives. PMID- 29183862 TI - The association of ERAP1 and ERAP2 single nucleotide polymorphisms and their haplotypes with psoriasis vulgaris is dependent on the presence or absence of the HLA-C*06:02 allele and age at disease onset. AB - The aim of this case-control study was to elucidate the role of some single nucleotide polymorphisms (SNPs) in the ERAP1 (rs27524, rs27044, rs30187, rs2287987 and rs26653) and ERAP2 (rs2248374) genes in predicting the risk for psoriasis vulgaris in the Polish population. ERAP1, ERAP2 and HLA-C*06:02 typing was done using the TaqMan SNP genotyping assays. We confirmed a strong association of the HLA-C*06:02 allele with early-onset psoriasis. In ERAP1, rs30187T increased the risk of psoriasis in HLA-C*06:02-positive patients, most strongly in late onset psoriasis, whereas it was protective when the HLA-C*06:02 allele was absent. We also found a protective effect of the ERAP2 rs2248374A allele and rs2248374AA genotype only in HLA-C*06:02 carriers, especially in the subgroup of patients with juvenile psoriasis. Analysis of combined haplotypes for ERAP1 and ERAP2 also revealed differences when the patients and controls were stratified by HLA-C*06:02. An ERAP1 haplotype known to possess high enzymatic activity was associated with psoriasis if HLA-C*06:02 was present and a functional ERAP2 allele was absent. In the absence of HLA-C*06:02, an ERAP1 haplotype of low activity was conducive to psoriasis if a functional ERAP2 allele was present, but the same ERAP1 haplotype was protective if the ERAP2 allele was defective. PMID- 29183864 TI - Surgery for Recurrent High-Grade Glioma After Treatment with Bevacizumab. AB - BACKGROUND: Bevacizumab (BVZ) is an antiangiogenic agent approved by the Food and Drug Administration that is used for the treatment of recurrent glioblastoma. Complications related to impaired healing may adversely affect patients resected for recurrent high-grade glioma (HGG) after treatment with BVZ. OBJECTIVE: To examine the complication rate, outcome, and tumor vasculature in patients resected for recurrent HGG after treatment with BVZ. METHODS: Data were reviewed retrospectively from patients undergoing surgery for recurrent HGG after treatment with BVZ. Results were compared with a control group of recurrently operated BVZ-naive HGG. Tumor samples and magnetic resonance imaging scans were analyzed. RESULTS: Fifteen patients underwent HGG resection after progression after BVZ. Forty-four BVZ-naive patients who underwent surgeries for tumor recurrence were included as controls. Median time from BVZ treatment to surgery was 30 days (2-107). Median overall survival from time of tumor diagnosis was 21.0 months (12-83.0), and median survival from post-BVZ surgery was 5.0 months (2.0-19.0), compared with 8.1 months in BVZ-naive controls measured from time of their last reoperation. Five of the 15 patients survived 6 or more months after post-BVZ surgery. Nine patients developed postsurgical complications requiring intervention. Complication rates for surgery after BVZ treatment were 66.7% compared with 38.6% in the control group (P = 0.077). We did not see overt changes in histopathology or immunohistochemistry staining; however, tumor vasculature in tumors resected after treatment with BVZ showed a significant decrease in mean vessel density. CONCLUSIONS: Surgery for recurrent HGG may be feasible in a select group of patients. Mean tumor vessel density may be decreased after treatment with BVZ. PMID- 29183865 TI - Intraventricular Glioblastoma Multiforme in A Child with L2-Hydroxyglutaric Aciduria. AB - L2-hydroxyglutaric aciduria (L2-HGA) is a rare neurometabolic disease characterized by accumulation of L2-hydroxyglutarate (L2-HG), a potential oncometabolite resulting in significant lifetime risk for cerebral tumors. Herein, we present a case of intraventricular glioblastoma multiforme (GBM) in a 16-year-old child with L2-HGA who presented with rapid functional decline and persistent vomiting. The tumor was completely resected, and the patient remained well at 2-year follow-up. Clinicians should be aware of the usual insidious nature of the disease. Rapid deterioration is unusual and should raise the suspicion of tumor development. This case also illustrates the importance of surveillance neuroimaging in patients with L2-HGA. To the best of our knowledge, only 1 case of GBM has been reported and it was sited in the temporal lobe, unlike the unusual intraventricular location in our case. PMID- 29183866 TI - An optimized whole blood assay measuring expression and activity of NLRP3, NLRC4 and AIM2 inflammasomes. AB - The proinflammatory protease caspase-1 plays pivotal roles in central pathways of innate immunity, thereby contributing to pathogen clearance. Beside its physiological role, dysregulated activity of caspase-1 is known to contribute to an increasing number of diseases. In this study, we optimized and validated a low volume human whole blood assay facilitating the measurement of caspase-1 activation and inflammasome-related gene expression upon stimulation of the NLRP3, NLRC4 or AIM2 inflammasome. Using the NLRP3 inflammasome specific inhibitor MCC950, we were able to measure the activity of canonical or alternative NLRP3 pathways, AIM2 and NLRC4 inflammasomes in whole blood. Based on our data we assume a superposition of NLRP3 and NLRC4 inflammasome activities in human whole blood following stimulation with S. typhimurium. The optimized whole blood assay may be suitable for diagnostic and research purposes for pediatric patients who can only donate small amounts of blood. PMID- 29183867 TI - The epidermal growth factor receptor inhibitor AG1478 inhibits eosinophilic inflammation in upper airways. AB - Mucus hypersecretion and eosinophil infiltration are important characteristics of eosinophilic inflammation in upper airways, such as allergic rhinitis and chronic rhinosinusitis with nasal polyp. EGFR transactivation induces mucus and inflammatory cytokine secretion from airway epithelial cells. However, the roles of EGFR in eosinophilic inflammation in upper airways are still unknown. The purpose of the study is to elucidate the effects of the EGFR inhibitor AG1478 on eosinophilic airway inflammation. AG1478 significantly inhibited thrombin-induced GM-CSF secretion from nasal epithelial cells and thrombin-induced secretion of eotaxin-1 and RANTES from nasal fibroblasts. Intranasal instillation of AG1478 inhibited OVA-induced goblet cell metaplasia, mucus production and eosinophil/neutrophil infiltration in rat nasal epithelium, as did intraperitoneal injection of AG1478. These results indicate that EGFR transactivation plays an important role in eosinophilic airway inflammation. Intranasal instillation of an EGFR inhibitor may be a new therapeutic approach for the treatment of intractable eosinophilic inflammation in upper airways. PMID- 29183868 TI - Providing Home-Based HIV Testing and Counseling for Transgender Youth (Project Moxie): Protocol for a Pilot Randomized Controlled Trial. AB - BACKGROUND: Transgender and gender nonconforming people experience some of the highest human immunodeficiency virus (HIV) rates in the United States, and experience many structural and behavioral barriers that may limit their engagement in HIV testing, prevention, and care. Evidence suggests that transgender and gender nonconforming youth (TY) are especially vulnerable to acquiring HIV, yet there is little research on TY and few services are targeted towards HIV testing, prevention, and care for this population. Telehealth presents an opportunity to mitigate some structural barriers that TY experience in accessing HIV testing, allowing TY to engage in HIV testing and counseling in a safe and nonjudgmental space of their choosing. Project Moxie is an HIV prevention intervention that pairs the use of HIV self-testing with remote video based counseling and support from a trained, gender-affirming counselor. This study aims to offer a more positive HIV testing and counseling experience, with the goal of improving HIV testing frequency. OBJECTIVE: Project Moxie involves a pilot randomized controlled trial (RCT) of 200 TY aged 15-24 years, who are randomized on a 1:1 basis to control or intervention arms. The aim is to examine whether the addition of counseling provided via telehealth, coupled with home based HIV testing, can create gains in routine HIV testing among TY over a six month follow-up period. METHODS: This study implements a prospective pilot RCT of 200 TY recruited online. Participants in the control arm will receive one HIV self-testing kit and will be asked to report their results via the study's website. Participants in the experimental arm will receive one HIV self-testing kit and will test with a remotely-located counselor during a prescheduled video counseling session. Participants are assessed at baseline, and at three and six months posttesting. RESULTS: Project Moxie was launched in June 2017 and recruitment is ongoing. As of August 21, 2017, the study had enrolled 130 eligible participants. CONCLUSIONS: Combining home-based HIV testing and video based counseling allows TY, an often stigmatized and marginalized population, to test for HIV in a safe and nonjudgmental setting of their choosing. This approach creates an opportunity to reduce the high rate of HIV among TY through engagement in care, support, and linkage to the HIV treatment cascade for those who test positive.

PMID- 29183869 TI - Detecting Acute Otitis Media Symptom Episodes Using a Mobile App: Cohort Study. AB - BACKGROUND: Population cohort studies are useful to study infectious diseases episodes not attended by health care services, but conventional paper diaries and questionnaires to capture cases are prone to noncompliance and recall bias. Use of smart technology in this setting may improve case finding. OBJECTIVE: The objective of our study was to validate an interactive mobile app for monitoring occurrence of acute infectious diseases episodes in individuals, independent of health care seeking, using acute otitis media (AOM) symptom episodes in infants as a case study. We were interested in determining participant compliance and app performance in detecting and ascertaining (parent-reported) AOM symptom episodes with this novel tool compared with traditional methods used for monitoring study participants. METHODS: We tested the InfectieApp research app to detect AOM symptom episodes. In 2013, we followed 155 children aged 0 to 3 years for 4 months. Parents recorded the presence of AOM symptoms in a paper diary for 4 consecutive months and completed additional disease questionnaires when AOM symptoms were present. In 2015 in a similar cohort of 69 children, parents used an AOM diary and questionnaire app instead. RESULTS: During conventional and app based recording, 93.13% (17,244/18,516) and 94.56% (7438/7866) of symptom diaries were returned, respectively, and at least one symptom was recorded for 32.50% (n=5606) and 43.99% (n=3272) of diary days (P<.01). The incidence of AOM symptom episodes was 605 and 835 per 1000 child-years, respectively. Disease questionnaires were completed for 59% (17/29) of episodes when participants were using conventional recording, compared with 100% (18/18) for app-based recording. CONCLUSIONS: The use of the study's smart diary app improved AOM case finding and disease questionnaire completeness. For common infectious diseases that often remain undetected by health care services, use of this technology can substantially improve the accurateness of disease burden estimates. PMID- 29183870 TI - Online Self-Management Support for Family Caregivers to Help Them Manage Behavior Changes in Their Relative With Dementia: Study Protocol for a Randomized Controlled Trial and a Process Evaluation. AB - BACKGROUND: Online interventions are potentially effective ways to support family caregivers in the management of behavior changes in their relative with dementia. OBJECTIVE: The objective of this paper is to present the design of a study evaluating and comparing 3 intervention arms for online self-management support. METHODS: A randomized controlled trial (RCT) will be conducted with a total of 81 family caregivers of community-dwelling people with dementia in the Netherlands. Family caregivers will be randomly allocated to one of the following intervention arms: (1) a major self-management support intervention consisting of personal email contacts with a nurse specialized in dementia care, online videos, and electronic bulletins (e-bulletins); (2) a medium self-management support intervention consisting of only online videos and e-bulletins; and (3) a minor self-management support intervention with only e-bulletins. The primary outcome is the self-efficacy of the family caregiver. The secondary outcomes are the behavior problems of the person with dementia as reported by the family caregiver, and positive and negative aspects of the relationship. Background characteristics (eg, type of family relationship) will also be assessed. All data for the RCT will be collected via online questionnaires, administered before the intervention (T0), after 6 weeks (T1), and after 12 weeks (T2). Alongside the RCT, a process evaluation will be conducted, based on a number of evaluation questions and semi-open interviews with family caregivers. RESULTS: Data collection will be completed in August 2017. Study results will be reported in early 2018. CONCLUSIONS: The study will shed more light on the effect of online self-management support interventions and insights will be gained into whether a major intervention, consisting of personal email contacts with specialized nurses, videos, and e-bulletins, has more effect than smaller online interventions. This is relevant in an age with increasing numbers of people with dementia, growing pressure on family caregivers, more and more people using the Internet, and increasing healthcare costs. TRIAL REGISTRATION: Nederlands Trial Registry (NTR): NTR6237; http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=6237 (Archived by WebCite at http://www.webcitation.org/6v0S4fxTC). PMID- 29183873 TI - Effect of chronic liraglutide therapy and its withdrawal on time to postchallenge peak glucose in type 2 diabetes. AB - Delayed timing of peak serum glucose following an oral glucose challenge can predict declining beta-cell function and worsening glucose tolerance over time. Accordingly, postchallenge peak glucose is typically delayed in patients with type 2 diabetes (T2DM). However, little is known about the capacity of antidiabetic medications to reverse this delay. Thus, we sought to evaluate the effect of the glucagon-like peptide-1 agonist liraglutide on time to peak glucose in early T2DM. In this secondary analysis of a double-blind placebo-controlled trial, 51 patients with T2DM of 2.6 +/- 1.9 yr duration were randomized to daily subcutaneous liraglutide or placebo injection for 48 wk, with oral glucose tolerance test (OGTT) performed every 12 wk while on therapy and after a 2-wk washout. On each OGTT, time to peak glucose was determined from venous glucose measurements at 0, 10, 20, 30, 60, 90, and 120 min. At randomization, most patients in both arms exhibited peak glucose at 90 min postchallenge. By 12 wk, 65.4% of the liraglutide arm had shifted to an earlier peak (vs. 36% on placebo; P = 0.19), with little change thereafter at 24, 36, and 48 wk. After the 2-wk washout, however, 57.7% of those who had been on liraglutide reverted to a later peak (vs. 4.5% on placebo; P < 0.001). This shift was associated with declining beta-cell function ( P = 0.001), resulting in higher 2-h blood glucose at washout in the liraglutide arm compared with placebo ( P = 0.001). Thus, although liraglutide possibly might improve the delay in peak glucose, its cessation yielded a worsening thereof and higher glycemia. The mechanisms underlying these observations and their clinical implications warrant further investigation. PMID- 29183872 TI - Endotoxin-initiated inflammation reduces testosterone production in men of reproductive age. AB - Inflammation, both acute and chronic, is associated with testosterone deficiency, raising the possibility of a direct causal link. One potential trigger for inflammation in obese men is the passage of intestinal bacteria into the circulation due to a breakdown in mucosal barrier integrity. Recently, we hypothesized that this endotoxin exposure may cause androgen deficiency in obese men. To test this hypothesis, we analyzed the relationship between serum levels of lipopolysaccharide-binding protein (LBP), an indirect measure of endotoxin exposure, against male reproductive hormones, inflammatory markers (C-reactive protein, IL-1beta, IL-6, TNF-alpha), and adiposity in 75 men. Adiposity was positively correlated with endotoxin exposure (LBP) and inflammation (C-reactive protein, IL-6) and negatively correlated with testosterone. Furthermore, endotoxemia (LBP) was negatively correlated with serum testosterone but positively correlated with IL-6. Multivariate analysis revealed a significant, negative correlation between serum IL-6 and free testosterone. In a second interventional study, low-dose endotoxin challenge in lean men produced a transient inflammatory response that was followed by a decline in serum testosterone, without changes in LH or FSH, providing further evidence that endotoxin-driven inflammation may result in impaired Leydig cell function. PMID- 29183874 TI - Which anticoagulant for stroke prevention in atrial fibrillation? PMID- 29183875 TI - Navigating chronic pain: how taking a few wrong turns can miss sinister pathology. AB - Bone sarcomas are rare in childhood, and their presentation can often mimic more benign complaints or chronic musculoskeletal pain. Ewing sarcomas in particular are often diagnosed after a significant delay from the onset of symptoms. At a population level, a long diagnostic delay is not necessarily associated with worse survival , as tumours that display slow growth also tend to be less aggressive. For any specific individual however, a delayed diagnosis can result in a larger tumour that is more difficult to treat. We explore a case of Ewing sarcoma and discuss how the presenting features, approach to imaging and the role of clinician cognitive bias may have led to diagnostic delay.Ewing sarcoma is treated with chemotherapy and surgery and/or radiotherapy based on the initial site of disease, size of tumour and response to initial treatment. With current UK treatments, overall survival is approximately 70% for localised tumours and up to 20% in those with metastatic disease. Bone sarcomas usually present with deep seated mechanical bone pain akin to toothache. The pain can be intermittent over the course of days or weeks, but pain occurring at night should be considered a red flag. Swelling may also present. On plain X-ray, bone sarcomas can demonstrate areas of bone destruction, new bone formation, periosteal inflammation and soft tissue swelling, but in some cases the changes are very subtle. Persistent unexplained symptoms require MRI to exclude tumours and detect potential benign causes that are amenable to treatment.

AB - OBJECTIVE: To describe the prevalence of fibromyalgia (FM) in an axial spondyloarthritis (axSpA) population and to confirm that concomitant FM had a negative impact on tumour necrosis factor blockers' (TNFb) response. DESIGN: Prospective observational study with two visits 3 months apart. PATIENTS: Adult patients with AxSpa initiating a TNFb. STUDY GROUPS: FM was defined by the Fibromyalgia Rapid Screening Tool (FiRST) at baseline and also by a sustained positive FiRST (both visits) and by a fulfilment of the 1990 American College of Rheumatology criteria for FM. STATISTICAL ANALYSIS: Prevalence of FM; evaluation of the impact of a concomitant FM on TNFb response (Bath Ankylosing Spondylitis Disease Activity Index (BASDAI 50) as primary endpoint), adjusted by factors known to have an impact on TNFb response. RESULTS: Among the 508 patients included in the main analysis, 192 (37.8%) were screened at baseline as FM. Percentage of success after 12 weeks of treatment was lower in the FM group for most of the effectiveness endpoints (eg, BASDAI 50: 45.3% vs 54.1% in the FM/not FM groups according to the FiRST), except for the C reactive protein change endpoints which were not different across groups. CONCLUSION: This study confirms that FM coexists in patients with axSpA and that its presence seems to have a negative impact on TNFb response, which seems more related to the self-reported instruments used in its evaluation, rather than a different treatment effect of the molecule in this subgroup of patients. PMID- 29183879 TI - Admission factors associated with international medical graduate certification success: a collaborative retrospective review of postgraduate medical education programs in Ontario. AB - BACKGROUND: The failure rate on certification examinations of The College of Family Physicians of Canada (CFPC) and the Royal College of Physicians and Surgeons of Canada (RCPSC) is significantly higher for international medical graduates than for Canadian medical school graduates. The purpose of the current study was to generate evidence that supports or refutes the validity of hypotheses proposed to explain the lower success rates. METHODS: We conducted retrospective analyses of admissions and certification data to determine the factors associated with success of international medical graduate residents on the certification examinations. International medical graduates who entered an Ontario residency program between 2005 and 2012 and had written a certification examination by the time of the analysis (2015) were included in the study. Data available at the time of admission for each resident, including demographic characteristics, previous experiences and previous professional experiences, were collected from each of the 6 Ontario medical schools and matched with certification examination results provided by The CFPC and the RCPSC. We developed logistic regression models to determine the association of each factor with success on the examinations. RESULTS: Data for 900 residents were analyzed. The models revealed resident age to be strongly associated with performance across all examinations. Fluency in English, female sex and the Human Development Index value associated with the country of medical school training had differential associations across the examinations. INTERPRETATION: The findings should contribute to an improved understanding of certification success by international medical graduates, help residency programs identify at-risk residents and underpin the development of specific educational and remedial interventions. In considering the results, it should be kept in mind that some variables are not amenable to changes in selection criteria.

AB - NHS-PROSPERO REGISTRATION NUMBER: 42016048592 OBJECTIVE: In order to make a more evidence-based selection of patients who would benefit the most from arthroscopic partial meniscectomy (APM), knowledge of prognostic factors is essential. We conducted a systematic review of predictors for the clinical outcome following APM. DESIGN: Systematic review DATA SOURCES: Medline, Embase, Cochrane Central Register, Web of Science, SPORTDiscus, PubMed Publisher, Google Scholar INCLUSION CRITERIA: Report an association between factor(s) and clinical outcome; validated questionnaire; follow-up >1 year. EXCLUSION CRITERIA: <20 subjects; anterior cruciate ligament-deficient patients; discoid menisci; meniscus repair, transplantation or implants; total or open meniscectomy. METHODS: One reviewer extracted the data, two reviewers assessed the risk of bias and performed a best evidence synthesis. RESULTS: Finally, 32 studies met the inclusion criteria. Moderate evidence was found, that the presence of radiological knee osteoarthritis at baseline and longer duration of symptoms (>1 year) are associated with worse clinical outcome following APM. In addition, resecting >50% of meniscal tissue and leaving a non-intact meniscal rim after meniscectomy are intra-articular predictive factors for worse clinical outcome. Moderate evidence was found that sex, onset of symptoms (acute or chronic), tear type or preoperative sport level are not predictors for clinical outcome. Conflicting evidence was found for the prognostic value of age, perioperative chondral damage, body mass index and leg alignment. SUMMARY/CONCLUSION: Long duration of symptoms (>1 year), radiological knee osteoarthritis and resecting >50% of meniscus are associated with a worse clinical outcome following APM. These prognostic factors should be considered in clinical decision making for patients with meniscal tears.

PMID- 29183887 TI - How I manage monoclonal gammopathy of undetermined significance. AB - Monoclonal gammopathy of undetermined significance (MGUS) is, in many ways, a unique hematologic entity. Unlike most hematologic conditions in which the diagnosis is intentional and credited to hematologists, the discovery of MGUS is most often incidental and made by nonhematologists. MGUS is considered an obligate precursor to several lymphoplasmacytic malignancies, including immunoglobulin light-chain amyloidosis, multiple myeloma, and Waldenstrom macroglobulinemia. Therefore, long-term follow-up is generally recommended. Despite its high prevalence, there is surprisingly limited evidence to inform best clinical practice both at the time of diagnosis and during follow-up. We present 7 vignettes to illustrate common clinical management questions that arise during the course of MGUS. Where evidence is present, we provide a concise summary of the literature and clear recommendations on management. Where evidence is lacking, we describe how we practice and provide a rationale for our approach. We also discuss the potential harms associated with MGUS diagnosis, a topic that is rarely, if ever, broached between patients and providers, or even considered in academic debate. PMID- 29183889 TI - Changes in regional body fat, lean body mass and body shape in trans persons using cross-sex hormonal therapy: results from a multicenter prospective study. AB - OBJECTIVE: Cross-sex hormonal therapy (CHT) in trans persons affects their total body fat and total lean body mass. However, it is unknown how separate body regions are affected and whether these changes alter body shape. Therefore, the aim of this study was to determine the effects on body fat and lean body mass in separate body regions and on body shape after one year of CHT. DESIGN AND METHODS: In a multicenter prospective study at university hospitals, 179 male-to female gender dysphoric persons, referred to as transwomen, and 162 female-to male gender dysphoric persons, referred to as transmen, were included. All underwent whole-body dual-energy X-ray absorptiometry and anthropometric measurements before and after one year of CHT. RESULTS: In transwomen, increases in body fat ranged from +18% (95% CI: 13%;23%) in the android region to +42% (95% CI: 37%;46%) in the leg region and +34% (95% CI: 29%;38%) in the gynoid region. In transmen, changes in body fat ranged from -16% (95% CI: -19;-14%) in the leg region and -14% in the gynoid region (95% CI: -16%;-12) to no change in the android region (+1%, 95% CI: -3%;5%). Waist-to-hip ratio (WHR) decreased in transwomen (-0.03, 95% CI: -0.04;-0.02) mainly due to an increase in hip circumference (+3.2 cm, 95% CI: 2.3;4.0). Transmen have a decrease in hip circumference (-1.9 cm, 95% CI: -3.1;-0.7) resulting in an increase in WHR (+0.01, 95% CI: 0.00;0.02). CONCLUSIONS: CHT causes a more feminine body fat distribution and a lower WHR in transwomen and a more masculine body fat distribution with a lower hip circumference in transmen.

PMID- 29183892 TI - Treatment of advanced colorectal cancer in a patient with cardiotoxic reactions to 5-fluorouracil and capecitabine using suboptimal doses. AB - A 32-year-old female with stage IV colorectal cancer and metastasis to the liver experienced cardiotoxic reactions after treatment with 5-fluorouracil and its oral prodrug capecitabine even at two-thirds the recommended dose. After careful considerations, the decision was made to attempt capecitabine retrial at a further suboptimal dose with combination chemotherapy where she no longer experienced cardiac events. As a result, the liver tumour shrank and rectal mass stabilised, tumour markers dropped and she underwent surgical resection of both masses. Later there was local recurrence of disease near the previous liver tumour, so the suboptimal capecitabine therapy was restarted without complaint. The patient became a candidate for a NanoKnife procedure, offering a potentially curative therapy. This case report summarises a novel treatment strategy for those patients with advanced colorectal cancer who experience cardiotoxic reactions to fluoropyrimidines, the active agent of gold standard treatment.

AB - A 21-year-old woman with moderate learning disability secondary to chromosome 2 microdeletion at q37 was admitted to a general adult psychiatric ward following a period of agitation with incessant pressure of speech, nihilistic delusions and worsening of sleep and eating patterns. Her presentation was preceded for a number of weeks by social stressors of an ill family member and another family member moving away. She had also been diagnosed and treated for a respiratory infection several weeks prior to presentation. Her presentation improved with low dose antipsychotic medication and parallel input from the general adult mental health team and the psychiatry of intellectual disability team. PMID- 29183894 TI - Dying art of a history and physical: pulsatile tinnitus. AB - Modern medicine often leaves the history and physical by the wayside. Physicians instead skip directly to diagnostic modalities like MRI and angiography. In this case report, we discuss a patient who presented with migraine symptoms. Auscultation revealed signs of pulsatile tinnitus. Further imaging concluded that it was secondary to a type I dural arteriovenous fistula. Thanks to a proper and thorough history and physical, the patient was streamlined into an accurate and efficient work-up leading to symptomatic relief and quality of life improvement. Imaging is a powerful adjunctive technique in modern medicine, but physicians must not rely on machines to diagnose their patients. If this trend continues, it will have a tremendous negative impact on the cost and calibre of healthcare. Our hope is that this case will spread awareness in the medical community, urging physicians to use the lost art of a history and physical. PMID- 29183891 TI - TEM8/ANTXR1-Specific CAR T Cells as a Targeted Therapy for Triple-Negative Breast Cancer. AB - Triple-negative breast cancer (TNBC) is an aggressive disease lacking targeted therapy. In this study, we developed a CAR T cell-based immunotherapeutic strategy to target TEM8, a marker initially defined on endothelial cells in colon tumors that was discovered recently to be upregulated in TNBC. CAR T cells were developed that upon specific recognition of TEM8 secreted immunostimulatory cytokines and killed tumor endothelial cells as well as TEM8-positive TNBC cells. Notably, the TEM8 CAR T cells targeted breast cancer stem-like cells, offsetting the formation of mammospheres relative to nontransduced T cells. Adoptive transfer of TEM8 CAR T cells induced regression of established, localized patient derived xenograft tumors, as well as lung metastatic TNBC cell line-derived xenograft tumors, by both killing TEM8+ TNBC tumor cells and targeting the tumor endothelium to block tumor neovascularization. Our findings offer a preclinical proof of concept for immunotherapeutic targeting of TEM8 as a strategy to treat TNBC.Significance: These findings offer a preclinical proof of concept for immunotherapeutic targeting of an endothelial antigen that is overexpressed in triple-negative breast cancer and the associated tumor vasculature.

The authors report a case of a 13-year-old male child who sustained type IV Salter-Harris injury to the medial malleolus with coronal spilt along with spilt and depressed fracture of the neck of talus and fracture of the lateral process of talus with stable compression fracture of spine sustained due to fall from 6 meters height. CT scan delineated the morphology of fracture pattern and helped in preoperative planning. Talar articular fracture was reduced and fixed arthroscopically while distal tibial fracture was fixed under image intensifier. We observed favourable outcome following arthroscopic reduction at 4-year follow-up. PMID- 29183897 TI - Puzzling thyroid function test. AB - A 13-1/2-year-old boy was referred to the Department of Endocrinology as a case of thyrotoxicosis for initiation of antithyroid medication. His chief complaint was a swelling in front of the neck, which was incidentally noted by his mother 2 weeks prior to presentation. He denied any history of symptoms suggestive of hyperthyroidism or ophthalmological involvement. His physical examination was unremarkable except for a grade 2 goitre. Thyroid function test revealed elevated free triiodothyronine and tetraiodothyronine in the face of an unsuppressed thyroid-stimulating hormone level. Technetium-99 uptake scan showed increased uptake indicating enhanced thyroid activity. However, he was clinically euthyroid. This raised the possibility of resistance to thyroid hormones, which was confirmed by documenting similar thyroid function test abnormalities in other members of his family and genetic testing. The family was reassured of the benign nature of the condition. PMID- 29183898 TI - Pirfenidone-induced hyponatraemia: insight in mechanism, risk factor and management. AB - Pirfenidone was approved in October 2014 in the USA for the treatment of idiopathic pulmonary fibrosis. Although not included in the adverse events published in the CAPACITY-1 and CAPACITY-2 or ASCEND trials, hyponatraemia was reported in supplementary data with rate of 3.4% in the active therapy arm versus 0.3% in the placebo arm. We performed a retrospective analysis of patients who were initiated on pirfenidone or nintedanib for the treatment of pulmonary fibrosis at our centre. Of the 52 patients who were started on pirfenidone, three (5.8%) developed severe hyponatraemia. Of the 29 patients who were started on nintedanib, none developed hyponatraemia. Laboratory data suggested syndrome of inappropriate antidiuretic hormone secretion (SIADH) induced by pirfenidone and the medication was discontinued. Hyponatraemia is a possible significant adverse effect of pirfenidone, able to induce SIADH in patients taking the medication.

PMID- 29183906 TI - Cardiac-enriched BAF chromatin-remodeling complex subunit Baf60c regulates gene expression programs essential for heart development and function. AB - How chromatin-remodeling complexes modulate gene networks to control organ specific properties is not well understood. For example, Baf60c (Smarcd3) encodes a cardiac-enriched subunit of the SWI/SNF-like BAF chromatin complex, but its role in heart development is not fully understood. We found that constitutive loss of Baf60c leads to embryonic cardiac hypoplasia and pronounced cardiac dysfunction. Conditional deletion of Baf60c in cardiomyocytes resulted in postnatal dilated cardiomyopathy with impaired contractile function. Baf60c regulates a gene expression program that includes genes encoding contractile proteins, modulators of sarcomere function, and cardiac metabolic genes. Many of the genes deregulated in Baf60c null embryos are targets of the MEF2/SRF co factor Myocardin (MYOCD). In a yeast two-hybrid screen, we identified MYOCD as a BAF60c interacting factor; we showed that BAF60c and MYOCD directly and functionally interact. We conclude that Baf60c is essential for coordinating a program of gene expression that regulates the fundamental functional properties of cardiomyocytes. PMID- 29183907 TI - A dual transcript-discovery approach to improve the delimitation of gene features from RNA-seq data in the chicken model. AB - The sequence of the chicken genome, like several other draft genome sequences, is presently not fully covered. Gaps, contigs assigned with low confidence and uncharacterized chromosomes result in gene fragmentation and imprecise gene annotation. Transcript abundance estimation from RNA sequencing (RNA-seq) data relies on read quality, library complexity and expression normalization. In addition, the quality of the genome sequence used to map sequencing reads, and the gene annotation that defines gene features, must also be taken into account. A partially covered genome sequence causes the loss of sequencing reads from the mapping step, while an inaccurate definition of gene features induces imprecise read counts from the assignment step. Both steps can significantly bias interpretation of RNA-seq data. Here, we describe a dual transcript-discovery approach combining a genome-guided gene prediction and a de novo transcriptome assembly. This dual approach enabled us to increase the assignment rate of RNA seq data by nearly 20% as compared to when using only the chicken reference annotation, contributing therefore to a more accurate estimation of transcript abundance. More generally, this strategy could be applied to any organism with partial genome sequence and/or lacking a manually-curated reference annotation in order to improve the accuracy of gene expression studies. PMID- 29183908 TI - Modulation of GLP-1 Levels by a Genetic Variant That Regulates the Cardiovascular Effects of Intensive Glycemic Control in ACCORD. AB - OBJECTIVE: A genome-wide association study in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial identified two markers (rs57922 and rs9299870) that were significantly associated with cardiovascular mortality during intensive glycemic control and could potentially be used, when combined into a genetic risk score (GRS), to identify patients with diabetes likely to derive benefit from intensive control rather than harm. The aim of this study was to gain insights into the pathways involved in the modulatory effect of these variants. RESEARCH DESIGN AND METHODS: Fasting levels of 65 biomarkers were measured at baseline and at 12 months of follow-up in the ACCORD-Memory in Diabetes (ACCORD-MIND) MRI substudy (n = 562). Using linear regression models, we tested the association of the GRS with baseline and 12-month biomarker levels, and with their difference (Delta), among white subjects, with genotype data (n = 351) stratified by intervention arm. RESULTS: A significant association was observed between GRS and DeltaGLP-1 (glucagon-like peptide 1, active) in the intensive arm (P = 3 * 10-4). This effect was driven by rs57922 (P = 5 * 10-4). C/C homozygotes, who had been found to derive cardiovascular benefits from intensive treatment, showed a 22% increase in GLP-1 levels during follow-up. By contrast, T/T homozygotes, who had been found to experience increased cardiac mortality with intensive treatment, showed a 28% reduction in GLP-1 levels. No association between DeltaGLP-1 and GRS or rs57922 was observed in the standard treatment arm. CONCLUSIONS: Differences in GLP-1 axis activation may mediate the modulatory effect of variant rs57922 on the cardiovascular response to intensive glycemic control. These findings highlight the importance of GLP-1 as a cardioprotective factor. PMID- 29183909 TI - Comparison of beta-Cell Function Between Overweight/Obese Adults and Adolescents Across the Spectrum of Glycemia. AB - OBJECTIVE: Type 2 diabetes is a growing health problem among both adults and adolescents. To better understand the differences in the pathogenesis of diabetes between these groups, we examined differences in beta-cell function along the spectrum of glucose tolerance. RESEARCH DESIGN AND METHODS: We evaluated 89 adults and 50 adolescents with normal glucose tolerance (NGT), dysglycemia, or type 2 diabetes. Oral glucose tolerance test results were used for C-peptide and insulin/glucose minimal modeling. Model-derived and direct measures of insulin secretion and insulin sensitivity were compared across glycemic stages and between age-groups at each stage. RESULTS: In adolescents with dysglycemia, there was marked insulin resistance (insulin sensitivity index: adolescents, median [interquartile range] 1.8 [1.1-2.4] * 10-4; adults, 5.0 [2.3-9.9]; P = 0.01). The nature of beta-cell dysfunction across stages of dysglycemia differed between the groups. We observed higher levels of secretion among adolescents than adults (total insulin secretion: NGT, 143 [103-284] * 10-9/min adolescent vs. 106 [71 127], P = 0.001); adults showed stepwise impairments in static insulin secretion (NGT, 7.5 [4.0-10.3] * 10-9/min; dysglycemia, 5.0 [2.3-9.9]; type 2 diabetes, 0.7 [0.1-2.45]; P = 0.003), whereas adolescents showed diabetes-related impairment in dynamic secretion (NGT, 1,905 [1,630-3,913] * 10-9; dysglycemia, 2,703 [1,323 3,637]; type 2 diabetes, 1,189 [269-1,410]; P = 0.001). CONCLUSIONS: Adults and adolescents differ in the underlying defects leading to dysglycemia, and in the nature of beta-cell dysfunction across stages of dysglycemia. These results may suggest different approaches to diabetes prevention in youths versus adults. PMID- 29183911 TI - David Oliver: Telehealth and telecare need a different approach. PMID- 29183910 TI - Predictors of Quality of Life and Other Patient-Reported Outcomes in the PANORAMA Multinational Study of People With Type 2 Diabetes. AB - OBJECTIVE: PANORAMA, a nine-country cross-sectional type 2 diabetes study, investigated factors associated with quality of life (QoL), health status, and other patient-reported outcome measures (PROMs). RESEARCH DESIGN AND METHODS: Patients were randomly or consecutively selected from primary/secondary care. PROMs included the Audit of Diabetes-Dependent Quality of Life (ADDQoL) (generic QoL item and average weighted impact [AWI] scores), Diabetes Treatment Satisfaction Questionnaire (DTSQ) (patient- and physician-completed), Hypoglycemia Fear Survey-II worry subscale, and the EuroQoL-5 Dimension visual analog scale (EQ-VAS) measuring patient-reported health. Multivariable linear regression analyses determined predictors of each PROM including patient characteristics, physician-reported adherence, complications, and glycosylated hemoglobin. RESULTS: In 5,813 patients, mean PROM scores indicated that generic QoL approximated "good" (0.93); perceived impact of diabetes on QoL was negative (AWI -1.69). Treatment satisfaction exceeded physicians' estimates (patient reported: 29.76; physician-estimated: 27.75), but so did patients' perceived frequency of hypo-/hyperglycemia. Worry about hypoglycemia (13.27) was apparent. Intensifying treatments to three oral agents or insulin regimens predicted worse QoL (AWI P < 0.01). Insulin alone use predicted worse QoL (generic P < 0.02; AWI P < 0.001) and hypoglycemia worry (P < 0.007). No treatment had significant associations with EQ-VAS health status. CONCLUSIONS: Predictors for different PROMs differed markedly and provided insights for understanding and improving these important outcomes. Intensive treatment regimens had significant negative associations with all PROMs, except the EQ-VAS health status measure. The findings demonstrate the importance of measuring QoL alongside health status and other patient-reported outcomes when evaluating diabetes treatments with a view to protecting QoL and facilitating adherence and long-term glycemic control.

AB - O-glycosylation is a post-translational modification of proteins crucial to molecular mechanisms in health and disease. O-glycans are typically highly heterogeneous. The involvement of specific O-glycan sequences in many bio recognition systems is yet to be determined because of a lack of efficient methodologies. We describe here a targeted microarray approach: O-glycome beam search that is both robust and efficient for O-glycan ligand-discovery. Substantial simplification of the complex O-glycome profile and facile chromatographic resolution is achieved by arraying O-glycans as branches, monitoring by mass spectrometry, focusing on promising fractions, and on-array immuno-sequencing. This is orders of magnitude more sensitive than traditional methods. We have applied beam search approach to porcine stomach mucin and identified extremely minor components previously undetected within the O-glycome of this mucin that are ligands for the adhesive proteins of two rotaviruses. The approach is applicable to O-glycome recognition studies in a wide range of biological settings to give insights into glycan recognition structures in natural microenvironments. PMID- 29183915 TI - Yeast Hog1 proteins are sequestered in stress granules during high-temperature stress. AB - The yeast high-osmolarity glycerol (HOG) pathway plays a central role in stress responses. It is activated by various stresses, including hyperosmotic stress, oxidative stress, high-temperature stress and exposure to arsenite. Hog1, the crucial MAP kinase of the pathway, localizes to the nucleus in response to high osmotic concentrations, i.e. high osmolarity; but, otherwise, little is known about its intracellular dynamics and regulation. By using the methylotrophic yeast Candida boidinii, we found that CbHog1-Venus formed intracellular dot structures after high-temperature stress in a reversible manner. Microscopic observation revealed that CbHog1-mCherry colocalized with CbPab1-Venus, a marker protein of stress granules. Hog1 homologs in Pichia pastoris and Schizosaccharomyces pombe also exhibited similar dot formation under high temperature stress, whereas Saccharomyces cerevisiae Hog1 (ScHog1)-GFP did not. Analysis of CbHog1-Venus in C. boidinii revealed that a beta-sheet structure in the N-terminal region was necessary and sufficient for its localization to stress granules. Physiological studies revealed that sequestration of activated Hog1 proteins in stress granules was responsible for downregulation of Hog1 activity under high-temperature stress.This article has an associated First Person interview with the first author of the paper. PMID- 29183913 TI - Spectral Library Based Analysis of Arginine Phosphorylations in Staphylococcus aureus. AB - Reversible protein phosphorylation is one of the major mechanisms in the regulation of protein expression and protein activity, controlling physiological functions of the important human pathogen Staphylococcus aureus Phosphorylations at serine, threonine and tyrosine are known to influence for example protein activity in central metabolic pathways and the more energy-rich phosphorylations at histidine, aspartate or cysteine can be found as part of two component system sensor domains or mediating bacterial virulence. In addition to these well-known phosphorylations, the phosphorylation at arginine residues plays an essential role. Hence, the deletion mutant S. aureus COL DeltaptpB (protein tyrosine phosphatase B) was studied because the protein PtpB is assumed to be an arginine phosphatase. A gel-free approach was applied to analyze the changes in the phosphoproteome of the deletion mutant DeltaptpB and the wild type in growing cells, thereby focusing on the occurrence of phosphorylation on arginine residues. In order to enhance the reliability of identified phosphorylation sites at arginine residues, a subset of arginine phosphorylated peptides was chemically synthesized. Combined spectral libraries based on phosphoenriched samples, synthetic arginine phosphorylated peptides and classical proteome samples provide a sophisticated tool for the analysis of arginine phosphorylations. This way, 212 proteins phosphorylated on serine, threonine, tyrosine or arginine residues were identified within the mutant DeltaptpB and 102 in wild type samples. Among them, 207 arginine phosphosites were identified exclusively within the mutant DeltaptpB, widely distributed along the whole bacterial metabolism. This identification of putative targets of PtpB allows further investigation of the physiological relevance of arginine phosphorylations and provides the basis for reliable quantification of arginine phosphorylations in bacteria.

AB - Aceruloplasminemia is a monogenic disease caused by mutations in the ceruloplasmin gene that result in loss of protein ferroxidase activity. Ceruloplasmin plays a role in iron homeostasis, and its activity impairment leads to iron accumulation in liver, pancreas, and brain. Iron deposition promotes diabetes, retinal degeneration, and progressive neurodegeneration. Current therapies mainly based on iron chelation, partially control systemic iron deposition but are ineffective on neurodegeneration. We investigated the potential of ceruloplasmin replacement therapy in reducing the neurological pathology in the ceruloplasmin-knockout (CpKO) mouse model of aceruloplasminemia. CpKO mice were intraperitoneal administered for 2 months with human ceruloplasmin that was able to enter the brain inducing replacement of the protein levels and rescue of ferroxidase activity. Ceruloplasmin-treated mice showed amelioration of motor incoordination that was associated with diminished loss of Purkinje neurons and reduced brain iron deposition, in particular in the choroid plexus. Computational analysis showed that ceruloplasmin-treated CpKO mice share a similar pattern with wild-type animals, highlighting the efficacy of the therapy. These data suggest that enzyme replacement therapy may be a promising strategy for the treatment of aceruloplasminemia. PMID- 29183918 TI - Factors Associated With Documentation of Obesity in the Inpatient Setting. AB - OBJECTIVES: Childhood obesity is rarely identified in hospitalized pediatric patients despite the high prevalence of obesity and potential for associated morbidity. The purpose of this study was to identify specific patient characteristics associated with the documentation of obesity and related weight management recommendations in the inpatient setting. METHODS: Retrospective chart review was conducted on all pediatric patients ages 2 to 18 years old and discharged between January 1, 2012, and December 31, 2014, to determine the following: (1) if obesity was noted in the clinical documentation of those with a BMI >=95th percentile; and (2) if those with documented obesity had evidence of an obesity-specific management plan. Using chi2 and multivariable logistic regression, we determined patient characteristics associated with the documentation of obesity and presence of a management plan. RESULTS: Only 26% (214 of 809) of inpatients with obesity had documentation of weight status. The odds of obesity documentation were higher in patients with comorbid cholelithiasis, severe obesity, and older age. Of those with obesity documentation, 23% (49 of 214) had an obesity management plan. Comorbid sleep apnea and admission to a surgical service with a pediatric hospital medicine consult were significantly associated with the presence of an obesity management plan. CONCLUSIONS: Increased efforts are necessary to improve obesity diagnosis and management in younger children who have not yet developed comorbidities. Additionally, the role of pediatric hospitalists as consultants for surgical patients should be further explored as a tool for addressing obesity during inpatient hospitalization.

Healthcare systems around the world have explored a variety of different services that divert AAI away from EDs to better manage their condition. Little formal evaluation has been undertaken, particularly in the UK where alcohol misuse is one of the highest in the world. In this article, we outline a brief history of diversionary services, introduce the concept of Alcohol Intoxication Management Services (AIMS) and describe examples of AIMS in the UK. We then describe Evaluating the Diversion of Alcohol-Related Attendances, a natural experiment including six cities with AIMS compared with six cities without, that involves an ethnographic study, records patient experiences in both AIMS and EDs, assesses impact on key performance indicators in healthcare and evaluates the cost-effectiveness of AIMS.

AB - INTRODUCTION: Benefit-cost analyses of tobacco regulations include estimates of the informed choice of smokers to continue smoking. Few studies have focused on subjective feelings associated with continued smoking. This study estimates how smoker discontent and regret relate to risk perceptions and health concerns. METHODS: We analysed data from a 2015 nationally representative, online survey of 1284 US adult current smokers. Information was collected on regret, intention to quit, perceived addiction, risk perceptions and health concerns. Multivariate logistic regression adjusting for sociodemographics and health status was used to examine factors associated with smoker discontent. RESULTS: More than 80% of current smokers report high (22.5%) or very high (59.8%) discontent due to inability to quit, perceived addiction and regret about having started to smoke. Higher levels of discontent did not vary significantly by sex, age, race/ethnicity, education or income (adjusted odds ratios (AORs) 0.5-1.2). Compared with the smokers expressing low (5.9%) or very low (3.6%) discontent, those expressing higher levels of discontent perceived their health status as fair/poor (AOR=2.3), worried most of the time about lung cancer (AOR=4.6) and felt they were more likely to develop lung cancer in the future (AOR=5.1). CONCLUSION: The proportion of smokers who might be characterised as having a preference to continue smoking are greatly outnumbered by addicted, discontent and concerned smokers who want to quit and regret ever having started to smoke. These discontent smokers could have a substantial net welfare gain if new regulations helped them escape their concerns about the health effects from continuing smoking.

AB - Immunohistochemistry is a valuable adjunct in routine gynaecological pathology. The molecular revolution has redesigned knowledge of gynaecological cancers and refined histological classification. The direct consequence has been the progressive introduction of new immunostainings for diagnostic and classification purposes. Hence, we review the routine diagnostic use of immunohistochemistry in the field of gynaecological neoplasia. We reviewed the immunomarkers useful in gynaecological pathology according to literature revision, our personal experience and research findings. We discuss the application of immunohistochemistry to reach the most accurate diagnosis in morphologically equivocal cases of gynaecological pathology and present the appropriate panel of immunomarkers in the most common scenarios of gynaecological pathology. This short review provides an updated overview of the essential immunohistochemical markers currently used in the diagnostics of gynaecological malignancies along with their molecular rationale.

PMID- 29183923 TI - RNA2DMut: a web tool for the design and analysis of RNA structure mutations. AB - With the widespread application of high-throughput sequencing, novel RNA sequences are being discovered at an astonishing rate. The analysis of function, however, lags behind. In both the cis- and trans-regulatory functions of RNA, secondary structure (2D base-pairing) plays essential regulatory roles. In order to test RNA function, it is essential to be able to design and analyze mutations that can affect structure. This was the motivation for the creation of the RNA2DMut web tool. With RNA2DMut, users can enter in RNA sequences to analyze, constrain mutations to specific residues, or limit changes to purines/pyrimidines. The sequence is analyzed at each base to determine the effect of every possible point mutation on 2D structure. The metrics used in RNA2DMut rely on the calculation of the Boltzmann structure ensemble and do not require a robust 2D model of RNA structure for designing mutations. This tool can facilitate a wide array of uses involving RNA: for example, in designing and evaluating mutants for biological assays, interrogating RNA-protein interactions, identifying key regions to alter in SELEX experiments, and improving RNA folding and crystallization properties for structural biology. Additional tools are available to help users introduce other mutations (e.g., indels and substitutions) and evaluate their effects on RNA structure. Example calculations are shown for five RNAs that require 2D structure for their function: the MALAT1 mascRNA, an influenza virus splicing regulatory motif, the EBER2 viral noncoding RNA, the Xist lncRNA repA region, and human Y RNA 5.

AB - OBJECTIVE: The proliferation of studies using motivational signs to promote stair use continues unabated, with their oft-cited potential for increasing population level physical activity participation. This study examined all stair use promotional signage studies since 1980, calculating pre-estimates and post estimates of stair use. The aim of this project was to conduct a sequential meta analysis to pool intervention effects, in order to determine when the evidence base was sufficient for population-wide dissemination. DESIGN: Using comparable data from 50 stair-promoting studies (57 unique estimates) we pooled data to assess the effect sizes of such interventions. RESULTS: At baseline, median stair usage across interventions was 8.1%, with an absolute median increase of 2.2% in stair use following signage-based interventions. The overall pooled OR indicated that participants were 52% more likely to use stairs after exposure to promotional signs (adjusted OR 1.52, 95% CI 1.37 to 1.70). Incremental (sequential) meta-analyses using z-score methods identified that sufficient evidence for stair use interventions has existed since 2006, with recent studies providing no further evidence on the effect sizes of such interventions. CONCLUSIONS: This analysis has important policy and practice implications. Researchers continue to publish stair use interventions without connection to policymakers' needs, and few stair use interventions are implemented at a population level. Researchers should move away from repeating short-term, small scale, stair sign interventions, to investigating their scalability, adoption and fidelity. Only such research translation efforts will provide sufficient evidence of external validity to inform their scaling up to influence population physical activity.

AB - PURPOSE: Globally, prostate cancer treatment and outcomes for men vary according to where they live, their race and the care they receive. The TrueNTH Global Registry project was established as an international registry monitoring care provided to men with localised prostate cancer (CaP). PARTICIPANTS: Sites with existing CaP databases in Movember fundraising countries were invited to participate in the international registry. In total, 25 Local Data Centres (LDCs) representing 113 participating sites across 13 countries have nominated to contribute to the project. It will collect a dataset based on the International Consortium for Health Outcome Measures (ICHOM) standardised dataset for localised CaP. FINDINGS TO DATE: A governance strategy has been developed to oversee registry operation, including transmission of reversibly anonymised data. LDCs are represented on the Project Steering Committee, reporting to an Executive Committee. A Project Coordination Centre and Data Coordination Centre (DCC) have been established. A project was undertaken to compare existing datasets, understand capacity at project commencement (baseline) to collect the ICHOM dataset and assist in determining the final data dictionary. 21/25 LDCs provided data dictionaries for review. Some ICHOM data fields were well collected (diagnosis, treatment start dates) and others poorly collected (complications, comorbidities). 17/94 (18%) ICHOM data fields were relegated to non-mandatory fields due to poor capture by most existing registries. Participating sites will transmit data through a web interface biannually to the DCC. FUTURE PLANS: Recruitment to the TrueNTH Global Registry-PCOR project will commence in late 2017 with sites progressively contributing reversibly anonymised data following ethical review in local regions. Researchers will have capacity to source deidentified data after the establishment phase. Quality indicators are to be established through a modified Delphi approach in later 2017, and it is anticipated that reports on performance against quality indicators will be provided to LDCs. PMID- 29183926 TI - Protocol for a feasibility randomised controlled trial of Screening and Enhanced Risk management for Vascular Event-related Decline in Memory (SERVED Memory). AB - INTRODUCTION: Stroke is a leading cause of death and disability. The development of dementia after stroke is common. Vascular risk factors (VRF) which contribute to stroke risk can also contribute to cognitive decline, especially in vascular dementia (VaD). There is no established treatment for VaD, therefore strategies for prevention could have major health resource implications. This study was designed to assess whether patients with early cognitive decline after stroke/transient ischaemic attack (TIA) can be easily identified and whether target-driven VRF management can prevent progression to dementia. OBJECTIVES: The primary objective is to establish the feasibility of recruitment and retention of patients with early cognitive decline to a randomised controlled trial of enhanced VRF management. Secondary objectives include: (a) to determine the potential clinical benefit of the intervention; (b) to estimate the sample size for a future definitive multicentre randomised controlled trial; (c) to inform a future economic evaluation; (d) to explore the link between VRF control and the incidence of cognitive impairment on longitudinal follow-up in a UK population after stroke/TIA with current routine management. METHODS: 100 patients with cognitive decline poststroke/TIA will be recruited from stroke services at the Norfolk and Norwich University Hospital. After collection of baseline data, they will be randomised to intervention (3 monthly follow-up with enhanced management) or control (treatment as usual by the general practitioner). At 12 months outcomes (repeat cognitive testing, VRF assessment) will be assessed. A further 100 patients without cognitive decline will be recruited to a parallel observational group from the same site. At 12 months they will have repeat cognitive testing. ETHICS AND DISSEMINATION: Ethical approval has been granted in England. Dissemination is planned via publication in peer-reviewed medical journals and presentation at relevant conferences.

AB - OBJECTIVES: To explore the views and experiences of people who are homeless and those supporting them regarding conversations and approaches to palliative care SETTING: Data were collected between October 2015 and October 2016 in homeless hostels and day centres and with staff from primary and secondary healthcare providers and social care services from three London boroughs. PARTICIPANTS: People experiencing homelessness (n=28), formerly homeless people (n=10), health and social care providers (n=48), hostel staff (n=30) and outreach staff (n=10). METHODS: In this qualitative descriptive study, participants were recruited to interviews and focus groups across three London boroughs. Views and experiences of end-of-life care were explored with people with personal experience of homelessness, health and social care professionals and hostel and outreach staff. Saturation was reached when no new themes emerged from discussions. RESULTS: 28 focus groups and 10 individual interviews were conducted. Participants highlighted that conversations exploring future care preferences and palliative care with people experiencing homelessness are rare. Themes identified as challenges to such conversations included attitudes to death; the recovery focused nature of services for people experiencing homelessness; uncertainty regarding prognosis and place of care; and fear of negative impact. CONCLUSIONS: This research highlights the need for a different approach to supporting people who are homeless and are experiencing advanced ill health, one that incorporates uncertainty and promotes well-being, dignity and choice. We propose parallel planning and mapping as a way of working with uncertainty. We acknowledge that these approaches will not always be straightforward, nor will they be suitable for everyone, yet moving the focus of conversations about the future away from death and dying, towards the present and the future may facilitate conversations and enable the wishes of people who are homeless to be known and explored. PMID- 29183928 TI - Viability testing and transplantation of marginal livers (VITTAL) using normothermic machine perfusion: study protocol for an open-label, non-randomised, prospective, single-arm trial. AB - INTRODUCTION: The use of marginal or extended criteria donor livers is increasing. These organs carry a greater risk of initial dysfunction and early failure, as well as inferior long-term outcomes. As such, many are rejected due to a perceived risk of use and use varies widely between centres. Ex situ normothermic machine perfusion of the liver (NMP-L) may enable the safe transplantation of organs that meet defined objective criteria denoting their high-risk status and are currently being declined for use by all the UK transplant centres. METHODS AND ANALYSIS: Viability testing and transplantation of marginal livers is an open-label, non-randomised, prospective, single-arm trial designed to determine whether currently unused donor livers can be salvaged and safely transplanted with equivalent outcomes in terms of patient survival. The procured rejected livers must meet predefined criteria that objectively denote their marginal condition. The liver is subjected to NMP-L following a period of static cold storage. Organs metabolising lactate to <=2.5 mmol/L within 4 hours of the perfusion commencing in combination with two or more of the following parameters-bile production, metabolism of glucose, a hepatic arterial flow rate >=150 mL/min and a portal venous flow rate >=500 mL/min, a pH >=7.30 and/or maintain a homogeneous perfusion-will be considered viable and transplanted into a suitable consented recipient. The coprimary outcome measures are the success rate of NMP-L to produce a transplantable organ and 90-day patient post-transplant survival. ETHICS AND DISSEMINATION: The protocol was approved by the National Research Ethics Service (London-Dulwich Research Ethics Committee, 16/LO/1056), the Medicines and Healthcare Products Regulatory Agency and is endorsed by the National Health Service Blood and Transplant Research, Innovation and Novel Technologies Advisory Group. The findings of this trial will be disseminated through national and international presentations and peer reviewed publications. TRIAL REGISTRATION NUMBER: NCT02740608; Pre-results. PMID- 29183929 TI - Effectiveness of inhaled corticosteroids in real life on clinical outcomes, sputum cells and systemic inflammation in asthmatics: a retrospective cohort study in a secondary care centre. AB - OBJECTIVES: The impact of inhaled corticosteroids (ICS) on eosinophilic inflammation in asthma is well established, but their effect in a real-life setting has not been extensively studied. Our purpose was to investigate the effect of ICS on airway and systemic inflammation as well as on clinical outcomes in patients with asthma from clinical practice. DESIGN, SETTING AND PARTICIPANTS: We conducted a retrospective analysis on asthmatics from a secondary care centre in whom ICS were initiated/increased (n=101), stopped/decreased (n=60) or remained stable (n=63, used as a control group) between two visits with available sputum and blood cell counts. RESULTS: The median time between both visits ranged from 1 to 2 years. Initiating or increasing ICS (median variation (IQR): 800 (400 1200) ug beclomethasone equivalent dose per day) reduced sputum eosinophils and fractional exhaled nitric oxide (P<0.0001) and to a lesser extent blood eosinophils (P<0.0001), while withdrawing or decreasing ICS (median variation (IQR): 900 (500-1200) ug beclomethasone equivalentdose per day) resulted in increased sputum eosinophils (P=0.008). No change was found in patients with a stable dose. The effectiveness of ICS in improving asthma control, quality of life, forced expiratory volume in 1 s (FEV1), bronchial hyper-responsiveness and exacerbation rate was only observed in the eosinophilic phenotype (sputum eosinophils >=3%, n=79). In non-eosinophilic asthmatics, stepping-down ICS resulted in an improvement in asthma control and quality of life, without any significant change in FEV1 (n=38). CONCLUSIONS: Our results confirm the effectiveness of ICS on eosinophilic inflammation in real life and demonstrate that their clinical benefit seems to be restricted to eosinophilic asthmatics. Our data also support a try for stepping-down ICS in non-eosinophilic asthmatics. PMID- 29183930 TI - Reducing catheter-associated urinary tract infections in hospitals: study protocol for a multi-site randomised controlled study. AB - INTRODUCTION: Despite advances in infection prevention and control, catheter associated urinary tract infections (CAUTIs) are common and remain problematic. A number of measures can be taken to reduce the risk of CAUTI in hospitals. Appropriate urinary catheter insertion procedures are one such method. Reducing bacterial colonisation around the meatal or urethral area has the potential to reduce CAUTI risk. However, evidence about the best antiseptic solutions for meatal cleaning is mixed, resulting in conflicting recommendations in guidelines internationally. This paper presents the protocol for a study to evaluate the effectiveness (objective 1) and cost-effectiveness (objective 2) of using chlorhexidine in meatal cleaning prior to catheter insertion, in reducing catheter-associated asymptomatic bacteriuria and CAUTI. METHODS AND ANALYSIS: A stepped wedge randomised controlled trial will be undertaken in three large Australian hospitals over a 32-week period. The intervention in this study is the use of chlorhexidine (0.1%) solution for meatal cleaning prior to catheter insertion. During the first 8 weeks of the study, no hospital will receive the intervention. After 8 weeks, one hospital will cross over to the intervention with the other two participating hospitals crossing over to the intervention at 8 week intervals respectively based on randomisation. All sites complete the trial at the same time in 2018. The primary outcomes for objective 1 (effectiveness) are the number of cases of CAUTI and catheter-associated asymptomatic bacteriuria per 100 catheter days will be analysed separately using Poisson regression. The primary outcome for objective 2 (cost-effectiveness) is the changes in costs relative to health benefits (incremental cost-effectiveness ratio) from adoption of the intervention. DISSEMINATION: Results will be disseminated via peer reviewed journals and presentations at relevant conferences.A dissemination plan it being developed. Results will be published in the peer review literature, presented at relevant conferences and communicated via professional networks. ETHICS: Ethics approval has been obtained.

PMID- 29183931 TI - Early low-energy versus high-energy enteral nutrition support in patients with traumatic intracerebral haemorrhage: protocol for a randomised controlled trial. AB - BACKGROUND: Early enteral nutrition (EN) is associated with shorter hospital stay and lower infection and mortality rates in patients with intracerebral haemorrhage. However, high-energy support always causes clinical complications, such as diarrhoea and aspiration pneumonia, and the true benefit of high-energy support in these patients has not been investigated. The appropriate amount of energy support still needs further investigation. Therefore, we are performing a randomised controlled trial to investigate whether early low-energy EN can decrease mortality and feeding-related complications and improve neurological outcomes as compared with high-energy EN in traumatic intracerebral haemorrhage (TICH) patients. METHODS/ANALYSIS: This is a randomised, single-blind clinical trial performed in one teaching hospital. 220 TICH patients will be randomly allocated to one of two groups in a 1:1 ratio: an intervention group, and a control group. The intervention group will receive early low-energy EN (10 kcal/kg/day) and the control group will receive high-energy EN (25 kcal/kg/day) for 7 days. All these patients will be followed up for 90 days. The primary outcome is all-cause 90-day mortality. Secondary outcomes include the modified Rankin score, Glasgow Outcome Scale (GOS) and the National Institutes of Health Stroke Scale (NIHSS). Outcomes will be assessed at admission, 7, 30 and 90 days after onset of this trial. The safety of EN strategies will be assessed every day during hospitalisation. ETHICS AND DISSEMINATION: The trial will be conducted in accordance with the Declaration of Helsinki and has been approved by the ethics committee of Dongyang People's Hospital. The findings will be published in peer reviewed medical journals. TRIAL REGISTRATION NUMBER: ChiCTR-INR-17011384; Pre results. PMID- 29183932 TI - Morphogenesis one century after On Growth and Form. PMID- 29183933 TI - On Growth and Form in context - an interview with Matthew Jarron. AB - D'Arcy Thompson was born in 1860, trained in Edinburgh and Cambridge, and held positions in Dundee and St Andrews, where he worked until his death in 1948. On Growth and Form, his classic work on the mathematical patterns and physical rules underlying biological forms, was first published in 1917. To learn more about the book's context, we met Matthew Jarron, Curator of Museum Services at the University of Dundee, in the University's D'Arcy Thompson Zoology Museum. Surrounded by specimens, many of which were collected by Thompson himself, we discussed the legacy of On Growth and Form and the life of the man behind it. PMID- 29183934 TI - On genes and form. AB - The mechanisms by which organisms acquire their sizes and shapes through growth was a major focus of D'Arcy Thompson's book On Growth and Form. By applying mathematical and physical principles to a range of biological forms, Thompson achieved fresh insights, such as the notion that diverse biological shapes could be related through simple deformations of a coordinate system. However, Thompson considered genetics to lie outside the scope of his work, even though genetics was a growing discipline at the time the book was published. Here, we review how recent advances in cell, developmental, evolutionary and computational biology allow Thompson's ideas to be integrated with genes and the processes they influence to provide a deeper understanding of growth and morphogenesis. We consider how genes interact with subcellular-, cellular- and tissue-level processes in plants to yield patterns of growth that underlie the developmental and evolutionary shape transformations Thompson so eloquently described. PMID- 29183935 TI - Computer modeling in developmental biology: growing today, essential tomorrow. AB - D'Arcy Thompson was a true pioneer, applying mathematical concepts and analyses to the question of morphogenesis over 100 years ago. The centenary of his famous book, On Growth and Form, is therefore a great occasion on which to review the types of computer modeling now being pursued to understand the development of organs and organisms. Here, I present some of the latest modeling projects in the field, covering a wide range of developmental biology concepts, from molecular patterning to tissue morphogenesis. Rather than classifying them according to scientific question, or scale of problem, I focus instead on the different ways that modeling contributes to the scientific process and discuss the likely future of modeling in developmental biology. PMID- 29183936 TI - 'The Forms of Tissues, or Cell-aggregates': D'Arcy Thompson's influence and its limits. AB - In two chapters of his book On Growth and Form, D'Arcy Thompson used numerous biological and physical observations to show how principles from mathematics and physics - such as pressure differences, surface tension and viscosity - could explain cell shapes and packing within tissues. In this Review, we depict influences that enabled the genesis of his ideas, report examples of his visionary observations and trace his impact over the past 100 years. Recently, his ideas have been revisited as a new field of research emerged, linking cell level physics with epithelial tissue structure and development. We critically discuss the potential and the limitations of both Thompson's and the modern approaches. PMID- 29183937 TI - Mechanical control of growth: ideas, facts and challenges. AB - In his classic book On Growth and Form, D'Arcy Thompson discussed the necessity of a physical and mathematical approach to understanding the relationship between growth and form. The past century has seen extraordinary advances in our understanding of biological components and processes contributing to organismal morphogenesis, but the mathematical and physical principles involved have not received comparable attention. The most obvious entry of physics into morphogenesis is via tissue mechanics. In this Review, we discuss the fundamental role of mechanical interactions between cells induced by growth in shaping a tissue. Non-uniform growth can lead to accumulation of mechanical stress, which in the context of two-dimensional sheets of tissue can specify the shape it assumes in three dimensions. A special class of growth patterns - conformal growth - does not lead to the accumulation of stress and can generate a rich variety of planar tissue shapes. Conversely, mechanical stress can provide a regulatory feedback signal into the growth control circuit. Both theory and experiment support a key role for mechanical interactions in shaping tissues and, via mechanical feedback, controlling epithelial growth. PMID- 29183938 TI - Tension, contraction and tissue morphogenesis. AB - D'Arcy Thompson was a proponent of applying mathematical and physical principles to biological systems, an approach that is becoming increasingly common in developmental biology. Indeed, the recent integration of quantitative experimental data, force measurements and mathematical modeling has changed our understanding of morphogenesis - the shaping of an organism during development. Emerging evidence suggests that the subcellular organization of contractile cytoskeletal networks plays a key role in force generation, while on the tissue level the spatial organization of forces determines the morphogenetic output. Inspired by D'Arcy Thompson's On Growth and Form, we review our current understanding of how biological forms are created and maintained by the generation and organization of contractile forces at the cell and tissue levels. We focus on recent advances in our understanding of how cells actively sculpt tissues and how forces are involved in specific morphogenetic processes. PMID- 29183940 TI - Mechanical regulation of musculoskeletal system development. AB - During embryogenesis, the musculoskeletal system develops while containing within itself a force generator in the form of the musculature. This generator becomes functional relatively early in development, exerting an increasing mechanical load on neighboring tissues as development proceeds. A growing body of evidence indicates that such mechanical forces can be translated into signals that combine with the genetic program of organogenesis. This unique situation presents both a major challenge and an opportunity to the other tissues of the musculoskeletal system, namely bones, joints, tendons, ligaments and the tissues connecting them. Here, we summarize the involvement of muscle-induced mechanical forces in the development of various vertebrate musculoskeletal components and their integration into one functional unit. PMID- 29183941 TI - The old and new faces of morphology: the legacy of D'Arcy Thompson's 'theory of transformations' and 'laws of growth'. AB - In 1917, the publication of On Growth and Form by D'Arcy Wentworth Thompson challenged both mathematicians and naturalists to think about biological shapes and diversity as more than a confusion of chaotic forms generated at random, but rather as geometric shapes that could be described by principles of physics and mathematics. Thompson's work was based on the ideas of Galileo and Goethe on morphology and of Russell on functionalism, but he was first to postulate that physical forces and internal growth parameters regulate biological forms and could be revealed via geometric transformations in morphological space. Such precise mathematical structure suggested a unifying generative process, as reflected in the title of the book. To Thompson it was growth that could explain the generation of any particular biological form, and changes in ontogeny, rather than natural selection, could then explain the diversity of biological shapes. Whereas adaptationism, widely accepted in evolutionary biology, gives primacy to extrinsic factors in producing morphological variation, Thompson's 'laws of growth' provide intrinsic directives and constraints for the generation of individual shapes, helping to explain the 'profusion of forms, colours, and other modifications' observed in the living world. PMID- 29183939 TI - Understanding the extracellular forces that determine cell fate and maintenance. AB - Stem cells interpret signals from their microenvironment while simultaneously modifying the niche through secreting factors and exerting mechanical forces. Many soluble stem cell cues have been determined over the past century, but in the past decade, our molecular understanding of mechanobiology has advanced to explain how passive and active forces induce similar signaling cascades that drive self-renewal, migration, differentiation or a combination of these outcomes. Improvements in stem cell culture methods, materials and biophysical tools that assess function have improved our understanding of these cascades. Here, we summarize these advances and offer perspective on ongoing challenges. PMID- 29183942 TI - Single-cell mechanical phenotype is an intrinsic marker of reprogramming and differentiation along the mouse neural lineage. AB - Cellular reprogramming is a dedifferentiation process during which cells continuously undergo phenotypical remodeling. Although the genetic and biochemical details of this remodeling are fairly well understood, little is known about the change in cell mechanical properties during the process. In this study, we investigated changes in the mechanical phenotype of murine fetal neural progenitor cells (fNPCs) during reprogramming to induced pluripotent stem cells (iPSCs). We find that fNPCs become progressively stiffer en route to pluripotency, and that this stiffening is mirrored by iPSCs becoming more compliant during differentiation towards the neural lineage. Furthermore, we show that the mechanical phenotype of iPSCs is comparable with that of embryonic stem cells. These results suggest that mechanical properties of cells are inherent to their developmental stage. They also reveal that pluripotent cells can differentiate towards a more compliant phenotype, which challenges the view that pluripotent stem cells are less stiff than any cells more advanced developmentally. Finally, our study indicates that the cell mechanical phenotype might be utilized as an inherent biophysical marker of pluripotent stem cells. PMID- 29183943 TI - Anisotropic shear stress patterns predict the orientation of convergent tissue movements in the embryonic heart. AB - Myocardial contractility and blood flow provide essential mechanical cues for the morphogenesis of the heart. In general, endothelial cells change their migratory behavior in response to shear stress patterns, according to flow directionality. Here, we assessed the impact of shear stress patterns and flow directionality on the behavior of endocardial cells, the specialized endothelial cells of the heart. At the early stages of zebrafish heart valve formation, we show that endocardial cells are converging to the valve-forming area and that this behavior depends upon mechanical forces. Quantitative live imaging and mathematical modeling allow us to correlate this tissue convergence with the underlying flow forces. We predict that tissue convergence is associated with the direction of the mean wall shear stress and of the gradient of harmonic phase-averaged shear stresses, which surprisingly do not match the overall direction of the flow. This contrasts with the usual role of flow directionality in vascular development and suggests that the full spatial and temporal complexity of the wall shear stress should be taken into account when studying endothelial cell responses to flow in vivo. PMID- 29183944 TI - Clones of cells switch from reduction to enhancement of size variability in Arabidopsis sepals. AB - Organs form with remarkably consistent sizes and shapes during development, whereas a high variability in growth is observed at the cell level. Given this contrast, it is unclear how such consistency in organ scale can emerge from cellular behavior. Here, we examine an intermediate scale, the growth of clones of cells in Arabidopsis sepals. Each clone consists of the progeny of a single progenitor cell. At early stages, we find that clones derived from a small progenitor cell grow faster than those derived from a large progenitor cell. This results in a reduction in clone size variability, a phenomenon we refer to as size uniformization. By contrast, at later stages of clone growth, clones change their growth pattern to enhance size variability, when clones derived from larger progenitor cells grow faster than those derived from smaller progenitor cells. Finally, we find that, at early stages, fast growing clones exhibit greater cell growth heterogeneity. Thus, cellular variability in growth might contribute to a decrease in the variability of clones throughout the sepal. PMID- 29183945 TI - Organ size control via hydraulically gated oscillations. AB - Hollow vesicular tissues of various sizes and shapes arise in biological organs such as ears, guts, hearts, brains and even entire organisms. Regulating their size and shape is crucial for their function. Although chemical signaling has been thought to play a role in the regulation of cellular processes that feed into larger scales, it is increasingly recognized that mechanical forces are involved in the modulation of size and shape at larger length scales. Motivated by a variety of examples of tissue cyst formation and size control that show simultaneous growth and size oscillations, we create a minimal theoretical framework for the growth and dynamics of a soft, fluid-permeable, spherical shell. We show that these shells can relieve internal pressure by bursting intermittently, shrinking and re-growing, providing a simple mechanism by which hydraulically gated oscillations can regulate size. To test our theory, we develop an in vitro experimental set-up to monitor the growth and oscillations of a hollow tissue spheroid growing freely or when confined. A simple generalization of our theory to account for irreversible deformations allows us to explain the time scales and the amplitudes of oscillations in terms of the geometry and mechanical properties of the tissue shells. Taken together, our theory and experimental observations show how soft hydraulics can regulate the size of growing tissue shells. PMID- 29183946 TI - An asymmetric attraction model for the diversity and robustness of cell arrangement in nematodes. AB - During early embryogenesis in animals, cells are arranged into a species-specific pattern in a robust manner. Diverse cell arrangement patterns are observed, even among close relatives. In the present study, we evaluated the mechanisms by which the diversity and robustness of cell arrangements are achieved in developing embryos. We successfully reproduced various patterns of cell arrangements observed in various nematode species in Caenorhabditis elegans embryos by altering the eggshell shapes. The findings suggest that the observed diversity of cell arrangements can be explained by differences in the eggshell shape. Additionally, we found that the cell arrangement was robust against eggshell deformation. Computational modeling revealed that, in addition to repulsive forces, attractive forces are sufficient to achieve such robustness. The present model is also capable of simulating the effect of changing cell division orientation. Genetic perturbation experiments demonstrated that attractive forces derived from cell adhesion are necessary for the robustness. The proposed model accounts for both diversity and robustness of cell arrangements, and contributes to our understanding of how the diversity and robustness of cell arrangements are achieved in developing embryos.

AB - OBJECTIVES: A 25% reduction of weekly work hours for full-time employees has been shown to improve sleep and alertness and reduce stress during both workdays and days off. The aim of the present study was to investigate how employees use their time during such an intervention: does total workload (paid and non-paid work) decrease, and recovery time increase, when work hours are reduced? METHODS: Full time employees within the public sector (n=636; 75% women) were randomised into intervention group and control group. The intervention group (n=370) reduced worktime to 75% with preserved salary during 18 months. Data were collected at baseline, after 9 months and 18 months. Time-use was reported every half-hour daily between 06:00 and 01:00 during 1 week at each data collection. Data were analysed with multilevel mixed modelling. RESULTS: Compared with the control group, the intervention group increased the time spent on domestic work and relaxing hobby activities during workdays when worktime was reduced (P<=0.001). On days off, more time was spent in free-time activities (P=0.003). Total workload decreased (-65 min) and time spent in recovery activities increased on workdays (+53 min). The pattern of findings was similar in subgroups defined by gender, family status and job situation. CONCLUSIONS: A worktime reduction of 25% for full-time workers resulted in decreased total workload and an increase of time spent in recovery activities, which is in line with the suggestion that worktime reduction may be beneficial for long-term health and stress.

AB - BACKGROUND AND PURPOSE: Spontaneous cerebellar intracerebral hemorrhage (ICH) has been reported to be mainly associated with vascular changes secondary to hypertension. However, a subgroup of cerebellar ICH seems related to vascular amyloid deposition (cerebral amyloid angiopathy). We sought to determine whether location of hematoma in the cerebellum (deep and superficial regions) was suggestive of a particular hemorrhage-prone small-vessel disease pathology (cerebral amyloid angiopathy or hypertensive vasculopathy). METHODS: Consecutive patients with cerebellar ICH from a single tertiary care medical center were recruited. Based on data from pathological reports, patients were divided according to the location of the primary cerebellar hematoma (deep versus superficial). Location of cerebral microbleeds (CMBs; strictly lobar, strictly deep, and mixed CMB) was evaluated on magnetic resonance imaging. RESULTS: One hundred and eight patients (84%) had a deep cerebellar hematoma, and 20 (16%) a superficial cerebellar hematoma. Hypertension was more prevalent in deep than in patients with superficial cerebellar ICH (89% versus 65%, respectively; P<0.05). Among patients who underwent magnetic resonance imaging, those with superficial cerebellar ICH had higher prevalence of strictly lobar CMB (43%) and lower prevalence of strictly deep or mixed CMB (0%) compared with those with deep superficial cerebellar ICH (6%, 17%, and 38%, respectively). In a multivariable model, presence of strictly lobar CMB was associated with superficial cerebellar ICH (odds ratio, 3.8; 95% confidence interval, 1.5-8.5; P=0.004). CONCLUSIONS: Our study showed that superficial cerebellar ICH is related to the presence of strictly lobar CMB-a pathologically proven marker of cerebral amyloid angiopathy. Cerebellar hematoma location may thus help to identify those patients likely to have cerebral amyloid angiopathy pathology.

AB - BACKGROUND AND PURPOSE: The aim of this article was to analyze the likelihood of receiving informal care after a stroke and to study the burden and risk of burnout of primary caregivers in Spain. METHODS: The CONOCES study is an epidemiological, observational, prospective, multicenter study of patients diagnosed with stroke and admitted to a Stroke Unit in the Spanish healthcare system. At 3 and 12 months post-event, we estimated the time spent caring for the patient and the burden borne by primary caregivers. Several multivariate models were applied to estimate the likelihood of receiving informal caregiving, the burden, and the likelihood of caregivers being at a high risk of burnout. RESULTS: Eighty percent of those still alive at 3 and 12 months poststroke were receiving informal care. More than 40% of those receiving care needed a secondary caregiver at 3 months poststroke. The likelihood of receiving informal care was associated with stroke severity and the individual's health-related quality of life. When informal care was provided, both the burden borne by caregivers and the likelihood of caregivers being at a high risk of burnout was associated with (1) caregiving hours; (2) the patient's health-related quality of life; (3) the severity of the stroke measured at discharge; (4) the patient having atrial fibrillation; and (5) the degree of dependence. CONCLUSIONS: This study reveals the heavy burden borne by the caregivers of stroke survivors. Our analysis also identifies explanatory and predictive variables for the likelihood of receiving informal care, caregiver burden, and high risk of burnout. PMID- 29183954 TI - Associations between objectively measured physical activity and later mental health outcomes in children: findings from the UK Millennium Cohort Study. AB - BACKGROUND: The beneficial effect of physical activity (PA) on mental health in adults is well established, but less is known about this relationship in children. We examine associations between objectively measured sedentary time, PA and mental health in 11-year-olds from the UK Millennium Cohort Study (MCS). METHODS: Longitudinal data from MCS sweeps 4 (age 7) and 5 (age 11) were used (n=6153). Accelerometer data were collected at MCS4, and mental health was measured at MCS4 and MCS5 using subscales (peer, emotional, conduct, hyperactivity) of the Strengths and Difficulties Questionnaire (SDQ). Associations between mean daily PA minutes at different intensities (sedentary, light, moderate-to-vigorous) at MCS4 and SDQ outcomes at MCS5 (score range 0-10) were estimated using multiple linear regression models, adjusting for SDQ at MCS4 and individual and family characteristics, and stratified by gender. RESULTS: In fully adjusted models, increased PA at MCS4 was associated with fewer peer problems in boys and girls at MCS5. For each additional 15 min in moderate-to vigorous physical activity (MVPA), peer problems decreased -0.077 points (95% CI 0.133 to -0.022) in boys. For girls, light PA was associated with decreased peer problems (-0.071 points/30 min, 95% CI -0.130 to -0.013). Greater sedentary time was associated with more peer problems and fewer hyperactivity symptoms in boys and girls. Increased MVPA was associated with more conduct and hyperactivity problems in boys and more hyperactivity in girls. CONCLUSIONS: Increased sedentary time is associated with more peer problems in children, and PA, generally, is beneficial for peer relations in children aged 11.

AB - BACKGROUND: It is unclear how psychosocial working conditions influence future alcohol consumption. Using group-based trajectory modelling, this study aimed to determine: the number of latent alcohol consumption trajectories over 16 years in a representative sample of the Canadian workforce; the association between psychosocial working conditions and longitudinal alcohol consumption; and if the association between psychosocial work factors and longitudinal alcohol consumption differed among men and women. METHODS: We included 5458 employed adults from the longitudinal Canadian National Population Health Survey. Average daily alcohol consumption was measured every 2 years from 1994 to 2010. Psychosocial work factors were measured in 1994 using the Job Content Questionnaire. Group-based trajectory modelling was used to derive the appropriate number of alcohol behaviour trajectories. The association between psychosocial work factors and alcohol trajectory membership was estimated using multinomial logistic regression. Models were stratified by sex to determine if these associations differed among men and women. RESULTS: Three alcohol consumption trajectories were present: non-drinkers, light drinkers (0.5-1 drinks/day) and moderate drinkers (2-3 drinks/day). Higher workplace physical exertion and lower social support levels were associated with membership in the moderate drinking trajectory. Among men, lower psychological demands and higher physical exertion levels were associated with membership in the moderate drinking trajectory. Among women, lower levels of physical exertion were associated with membership in the light drinking trajectory, and higher psychological demand levels were associated with membership in the moderate drinking trajectory. CONCLUSIONS: Our study suggests that workplace physical exertion and psychological demands may be associated with different alcohol consumption trajectories among men and women. PMID- 29183956 TI - Generalisability of an online randomised controlled trial: an empirical analysis. AB - BACKGROUND: Investigators increasingly use online methods to recruit participants for randomised controlled trials (RCTs). However, the extent to which participants recruited online represent populations of interest is unknown. We evaluated how generalisable an online RCT sample is to men who have sex with men in China. METHODS: Inverse probability of sampling weights (IPSW) and the G formula were used to examine the generalisability of an online RCT using model based approaches. Online RCT data and national cross-sectional study data from China were analysed to illustrate the process of quantitatively assessing generalisability. The RCT (identifier NCT02248558) randomly assigned participants to a crowdsourced or health marketing video for promotion of HIV testing. The primary outcome was self-reported HIV testing within 4 weeks, with a non inferiority margin of -3%. RESULTS: In the original online RCT analysis, the estimated difference in proportions of HIV tested between the two arms (crowdsourcing and health marketing) was 2.1% (95% CI, -5.4% to 9.7%). The hypothesis that the crowdsourced video was not inferior to the health marketing video to promote HIV testing was not demonstrated. The IPSW and G-formula estimated differences were -2.6% (95% CI, -14.2 to 8.9) and 2.7% (95% CI, -10.7 to 16.2), with both approaches also not establishing non-inferiority. CONCLUSIONS: Conducting generalisability analysis of an online RCT is feasible. Examining the generalisability of online RCTs is an important step before an intervention is scaled up.

AB - BACKGROUND: Being married is associated with healthier lifestyle behaviours and lower mortality and may reduce risk for dementia due to life-course factors. We conducted a systematic review and meta-analysis of studies of the association between marital status and the risk of developing dementia. METHODS: We searched medical databases and contacted experts in the field for relevant studies reporting the relationship, adjusted for age and sex, between marital status and dementia. We rated methodological quality and conducted random-effects meta analyses to summarise relative risks of being widowed, divorced or lifelong single, compared with being married. Secondary stratified analyses with meta regression examined the impact of clinical and social context and study methodology on findings. RESULTS: We included 15 studies with 812 047 participants. Compared with those who are married, lifelong single (relative risk=1.42 (95% CI 1.07 to 1.90)) and widowed (1.20 (1.02 to 1.41)) people have elevated risk of dementia. We did not find an association in divorced people.Further analyses showed that less education partially confounds the risk in widowhood and worse physical health the elevated risk in lifelong single people. Compared with studies that used clinical registers for ascertaining dementia diagnoses, those which clinically examined all participants found higher risk for being unmarried. CONCLUSIONS: Being married is associated with reduced risk of dementia than widowed and lifelong single people, who are also underdiagnosed in routine clinical practice. Dementia prevention in unmarried people should focus on education and physical health and should consider the possible effect of social engagement as a modifiable risk factor.

PMID- 29183959 TI - Stereotactic EEG-guided laser interstitial thermal therapy for mesial temporal lobe epilepsy. AB - OBJECTIVE: To determine the outcomes of combined stereo-electroencephalography guided and MRI-guided stereotactic laser interstitial thermal therapy (LITT) in the treatment of patients with drug-resistant mesial temporal lobe epilepsy (mTLE). METHODS: We prospectively assessed the surgical and neuropsychological outcomes in 21 patients with medically refractory mTLE who underwent LITT at the University of Chicago Medical Center. We further compared the surgical outcomes in patients with and without mesial temporal sclerosis (MTS). RESULTS: Of the 21 patients, 19 (90%) underwent Invasive EEG study and 11 (52%) achieved freedom from disabling seizures with a mean duration of postoperative follow-up of 24+/ 11 months after LITT. Eight (73%) of 11 patients with MTS achieved freedom from disabling seizures, whereas 3 (30 %) of 10 patients without MTS achieved freedom from disabling seizures. Patients with MTS were significantly more likely to become seizure-free, as compared with those without MTS (P=0.002). There was no significant difference in total ablation volume and the percentage of the ablated amygdalohippocampal complex between seizure-free and non-seizure-free patients. Presurgical and postsurgical neuropsychological assessments were obtained in 10 of 21 patients. While there was no group decline in any neuropsychological assessment, a significant postoperative decline in verbal memory and confrontational naming was observed in individual patients. CONCLUSIONS: MRI guided LITT is a safe and effective alternative to selective amygdalohippocampectomy and anterior temporal lobectomy for mTLE with MTS. Nevertheless, its efficacy in those without MTS seems modest. Large multicentre and prospective studies are warranted to further determine the efficacy and safety of LITT. PMID- 29183960 TI - Radium-223 Safety, Efficacy, and Concurrent Use with Abiraterone or Enzalutamide: First U.S. Experience from an Expanded Access Program. AB - BACKGROUND: In the phase III ALSYMPCA trial, metastatic castration-resistant prostate cancer (mCRPC) patients had few prior life-prolonging therapies. Following ALSYMPCA, which demonstrated radium-223 survival benefit, and before radium-223 U.S. commercial availability, an expanded access program (EAP) providing early-access radium-223 allowed life-prolonging therapies in current use. SUBJECTS, MATERIALS, AND METHODS: This phase II, open-label, single-arm, multicenter U.S. EAP (NCT01516762) enrolled patients with symptomatic mCRPC, >=2 bone metastases, and no lung, liver, or brain metastases. Patients received radium-223 55 kBq/kg intravenously every 4 weeks * 6. Primary outcomes were acute and long-term safety. Additional analyses were done by number of radium-223 injections, and prior or concomitant abiraterone or enzalutamide use. RESULTS: Of 252 patients, 184 received radium-223: 165/184 (90%) had Eastern Cooperative Oncology Group (ECOG) performance status 0-1; 183 (99%) had prior systemic anticancer therapy. Treatment-related adverse events occurred in 93/184 (51%) patients during treatment and 11 (6%) during follow-up. Median overall survival was 17 months, with 134/184 (73%) patients censored because of short follow-up due to radium-223 approval. In post hoc analyses, patients with >=3 prior anticancer medications, baseline ECOG performance status >=2, and lower baseline hemoglobin were less likely to receive 5-6 radium-223 injections and unlikely to benefit from radium-223. Radium-223 was well tolerated regardless of concurrent or prior abiraterone or enzalutamide. CONCLUSION: Radium-223 was well tolerated, with no new safety concerns; safety was maintained with abiraterone or enzalutamide. Patients with more advanced disease were less likely to benefit from radium-223. Clinicians should consider baseline characteristics and therapy sequence for greatest clinical value. IMPLICATIONS FOR PRACTICE: In this phase II U.S. expanded access program, radium-223 was well tolerated, with a median overall survival of 17 months in metastatic castration-resistant prostate cancer patients. In post hoc analyses, radium-223 was safe regardless of concurrent abiraterone or enzalutamide, and median overall survival appeared longer when radium-223 was used earlier in patients with less prior treatment. Patients with more advanced disease were less likely to benefit from radium-223. Clinicians should consider baseline clinical characteristics and therapy sequence to provide the greatest clinical value to patients. PMID- 29183962 TI - Intestinal lymphatic HDL miR-223 and ApoA-I are reduced during insulin resistance and restored with niacin. AB - The intestine is involved in whole-body lipid and cholesterol homeostasis and secretes lipoproteins containing apolipoprotein (Apo)B48 and discrete ApoA-I into the mesenteric lymph. The lymphatic system has been proposed to have a significant role in the reverse cholesterol transport pathway associated with HDL ApoA-I. In conditions of insulin resistance (IR), there is intestinal overproduction of chylomicrons containing ApoB48; however, there is limited data on the intestinal synthesis and secretion of HDL-ApoA-I. microRNA (miR)-223 has been shown to regulate peripheral HDL metabolism and may impact intestinal derived HDL. Niacin (nicotinic acid; vitamin B3) is known to regulate lipid metabolism, but the role of niacin in modulating intestinal lipid and lipoprotein (ApoB48 and ApoA-I) metabolism is unknown. The aim of this study was to determine the secretion of intestinal lymphatic HDL-ApoA-I and the effect of dietary intervention with niacin on these pathways in a rodent model of IR. HDL was isolated from intestinal mesenteric lymph by density ultracentrifugation, and subsequent HDL miR analysis was developed in collaboration with Exiqon Services. Insulin-resistant rodents were fed chow or chow with niacin (1% w/w) for 6 wk. Intestinal lymph HDL-ApoA-I and miR-223 expression were lower by at least 45 and 60%, respectively, and lymph HDL was associated with 85% higher triglyceride (TG) content in IR compared to non-IR control group. Niacin was found to increase secretion of lymph HDL and miR-223 by at least 50-60% and to deplete the TGs associated with HDL compared with the nontreated IR group. Niacin significantly increased peroxisome proliferator-activating nuclear receptor alpha and carnitine palmitoyltransferase I alpha mRNA and annulled Tnf-alpha mRNA expression in intestinal (jejunal) explants. Altered intestinal lymphatic HDL-ApoA-I and miR 223 metabolism in IR and modulation by niacin may provide insight into the intestinal-mediated regulation of the reverse cholesterol transport pathway.

AB - Objective To compare the efficacy, safety, and cost effectiveness of direct acting oral anticoagulants (DOACs) for patients with atrial fibrillation.Design Systematic review, network meta-analysis, and cost effectiveness analysis. Data sources Medline, PreMedline, Embase, and The Cochrane Library.Eligibility criteria for selecting studies Published randomised trials evaluating the use of a DOAC, vitamin K antagonist, or antiplatelet drug for prevention of stroke in patients with atrial fibrillation.Results 23 randomised trials involving 94 656 patients were analysed: 13 compared a DOAC with warfarin dosed to achieve a target INR of 2.0-3.0. Apixaban 5 mg twice daily (odds ratio 0.79, 95% confidence interval 0.66 to 0.94), dabigatran 150 mg twice daily (0.65, 0.52 to 0.81), edoxaban 60 mg once daily (0.86, 0.74 to 1.01), and rivaroxaban 20 mg once daily (0.88, 0.74 to 1.03) reduced the risk of stroke or systemic embolism compared with warfarin. The risk of stroke or systemic embolism was higher with edoxaban 60 mg once daily (1.33, 1.02 to 1.75) and rivaroxaban 20 mg once daily (1.35, 1.03 to 1.78) than with dabigatran 150 mg twice daily. The risk of all-cause mortality was lower with all DOACs than with warfarin. Apixaban 5 mg twice daily (0.71, 0.61 to 0.81), dabigatran 110 mg twice daily (0.80, 0.69 to 0.93), edoxaban 30 mg once daily (0.46, 0.40 to 0.54), and edoxaban 60 mg once daily (0.78, 0.69 to 0.90) reduced the risk of major bleeding compared with warfarin. The risk of major bleeding was higher with dabigatran 150 mg twice daily than apixaban 5 mg twice daily (1.33, 1.09 to 1.62), rivaroxaban 20 mg twice daily than apixaban 5 mg twice daily (1.45, 1.19 to 1.78), and rivaroxaban 20 mg twice daily than edoxaban 60 mg once daily (1.31, 1.07 to 1.59). The risk of intracranial bleeding was substantially lower for most DOACs compared with warfarin, whereas the risk of gastrointestinal bleeding was higher with some DOACs than warfarin. Apixaban 5 mg twice daily was ranked the highest for most outcomes, and was cost effective compared with warfarin.Conclusions The network meta-analysis informs the choice of DOACs for prevention of stroke in patients with atrial fibrillation. Several DOACs are of net benefit compared with warfarin. A trial directly comparing DOACs would overcome the need for indirect comparisons to be made through network meta-analysis.Systematic review registration PROSPERO CRD 42013005324. PMID- 29183963 TI - Distinct moieties underlie biphasic H+ gating of connexin43 channels, producing a pH optimum for intercellular communication. AB - Most mammalian cells can intercommunicate via connexin-assembled, gap-junctional channels. To regulate signal transmission, connexin (Cx) channel permeability must respond dynamically to physiological and pathophysiological stimuli. One key stimulus is intracellular pH (pHi), which is modulated by a tissue's metabolic and perfusion status. Our understanding of the molecular mechanism of H+ gating of Cx43 channels-the major isoform in the heart and brain-is incomplete. To interrogate the effects of acidic and alkaline pHi on Cx43 channels, we combined voltage-clamp electrophysiology with pHi imaging and photolytic H+ uncaging, performed over a range of pHi values. We demonstrate that Cx43 channels expressed in HeLa or N2a cell pairs are gated biphasically by pHi via a process that consists of activation by H+ ions at alkaline pHi and inhibition at more acidic pHi. For Cx43 channel-mediated solute/ion transmission, the ensemble of these effects produces a pHi optimum, near resting pHi. By using Cx43 mutants, we demonstrate that alkaline gating involves cysteine residues of the C terminus and is independent of motifs previously implicated in acidic gating. Thus, we present a molecular mechanism by which cytoplasmic acid-base chemistry fine tunes intercellular communication and establishes conditions for the optimal transmission of solutes and signals in tissues, such as the heart and brain.

However, the role of germ cells in BTB assembly remains unclear. Herein, KitW/KitWV mice were used as a study model. These mice were infertile, failing to establish a functional BTB to support meiosis due to c Kit mutation. Transplantation of undifferentiated spermatogonia derived from normal mice into the testis of KitW/KitWV mice triggered functional BTB assembly, displaying cyclic remodeling during the epithelial cycle. Also, transplanted germ cells were capable of inducing Leydig cell testosterone production, which could enhance the expression of integral membrane protein claudin 3 in Sertoli cells. Early spermatocytes were shown to play a vital role in directing BTB assembly by expressing claudin 3, which likely created a transient adhesion structure to mediate BTB and cytoskeleton assembly in adjacent Sertoli cells. In summary, the positive modulation of germ cells on somatic cell function provides useful information regarding somatic-germ cell interactions.-Li, X.-Y., Zhang, Y., Wang, X.-X., Jin, C., Wang, Y.-Q., Sun, T.-C., Li, J., Tang, J.-X., Batool, A., Deng, S.-L., Chen, S.-R., Cheng, C.

AB - Elevated kynurenine (Kyn) production from tryptophan (Trp) metabolism is a biomarker of immune dysregulation in depression, but its mechanistic contributions to the behavioral symptoms are poorly defined. In this study, Kyn was shown to be a metabolic regulator of proinflammatory monocytes that orchestrated peripheral immune activation and neuroinflammation in depressive mice. Kyn-induced depressive behavior was paralleled by brain infiltration of proinflammatory monocytes and astrocytic activation. Kyn enhanced chemokine (C-C motif) ligand-2-mediated chemotaxis of monocytes and their proinflammatory capability on cocultured astrocytes in vitro, which involved the activation of aryl hydrocarbon receptor (AhR) signaling. Kyn augmented, whereas pharmacological AhR blockade rescued, systemic inflammation-induced monocyte trafficking, neuroimmune disturbance, and depressive-like behavior in mice. The behavior exacerbating effects of the Kyn-AhR axis were dampened with prior depletion of functional monocytes in the periphery. The findings in our study extend understanding of an immunologic effect of Kyn that links Trp metabolism and inflammatory signaling in depression pathology, with potential therapeutic implications for depressive disorders.-Zang, X., Zheng, X., Hou, Y., Hu, M., Wang, H., Bao, X., Zhou, F., Wang, G., Hao, H.

PMID- 29183966 TI - Equilibration of energy in slow-fast systems. AB - Ergodicity is a fundamental requirement for a dynamical system to reach a state of statistical equilibrium. However, in systems with several characteristic timescales, the ergodicity of the fast subsystem impedes the equilibration of the whole system because of the presence of an adiabatic invariant. In this paper, we show that violation of ergodicity in the fast dynamics can drive the whole system to equilibrium. To show this principle, we investigate the dynamics of springy billiards, which are mechanical systems composed of a small particle bouncing elastically in a bounded domain, where one of the boundary walls has finite mass and is attached to a linear spring. Numerical simulations show that the springy billiard systems approach equilibrium at an exponential rate. However, in the limit of vanishing particle-to-wall mass ratio, the equilibration rates remain strictly positive only when the fast particle dynamics reveal two or more ergodic components for a range of wall positions. For this case, we show that the slow dynamics of the moving wall can be modeled by a random process. Numerical simulations of the corresponding springy billiards and their random models show equilibration with similar positive rates. PMID- 29183967 TI - Using deep learning and Google Street View to estimate the demographic makeup of neighborhoods across the United States. AB - The United States spends more than $250 million each year on the American Community Survey (ACS), a labor-intensive door-to-door study that measures statistics relating to race, gender, education, occupation, unemployment, and other demographic factors. Although a comprehensive source of data, the lag between demographic changes and their appearance in the ACS can exceed several years. As digital imagery becomes ubiquitous and machine vision techniques improve, automated data analysis may become an increasingly practical supplement to the ACS. Here, we present a method that estimates socioeconomic characteristics of regions spanning 200 US cities by using 50 million images of street scenes gathered with Google Street View cars. Using deep learning-based computer vision techniques, we determined the make, model, and year of all motor vehicles encountered in particular neighborhoods. Data from this census of motor vehicles, which enumerated 22 million automobiles in total (8% of all automobiles in the United States), were used to accurately estimate income, race, education, and voting patterns at the zip code and precinct level. (The average US precinct contains ~1,000 people.) The resulting associations are surprisingly simple and powerful. For instance, if the number of sedans encountered during a drive through a city is higher than the number of pickup trucks, the city is likely to vote for a Democrat during the next presidential election (88% chance); otherwise, it is likely to vote Republican (82%). Our results suggest that automated systems for monitoring demographics may effectively complement labor intensive approaches, with the potential to measure demographics with fine spatial resolution, in close to real time. PMID- 29183969 TI - Relationship of tropospheric stability to climate sensitivity and Earth's observed radiation budget. AB - Climate feedbacks generally become smaller in magnitude over time under CO2 forcing in coupled climate models, leading to an increase in the effective climate sensitivity, the estimated global-mean surface warming in steady state for doubled CO2 Here, we show that the evolution of climate feedbacks in models is consistent with the effect of a change in tropospheric stability, as has recently been hypothesized, and the latter is itself driven by the evolution of the pattern of sea-surface temperature response. The change in climate feedback is mainly associated with a decrease in marine tropical low cloud (a more positive shortwave cloud feedback) and with a less negative lapse-rate feedback, as expected from a decrease in stability. Smaller changes in surface albedo and humidity feedbacks also contribute to the overall change in feedback, but are unexplained by stability. The spatial pattern of feedback changes closely matches the pattern of stability changes, with the largest increase in feedback occurring in the tropical East Pacific. Relationships qualitatively similar to those in the models among sea-surface temperature pattern, stability, and radiative budget are also found in observations on interannual time scales. Our results suggest that constraining the future evolution of sea-surface temperature patterns and tropospheric stability will be necessary for constraining climate sensitivity. PMID- 29183968 TI - Catch bond drives stator mechanosensitivity in the bacterial flagellar motor. AB - The bacterial flagellar motor (BFM) is the rotary motor that rotates each bacterial flagellum, powering the swimming and swarming of many motile bacteria. The torque is provided by stator units, ion motive force-powered ion channels known to assemble and disassemble dynamically in the BFM. This turnover is mechanosensitive, with the number of engaged units dependent on the viscous load experienced by the motor through the flagellum. However, the molecular mechanism driving BFM mechanosensitivity is unknown. Here, we directly measure the kinetics of arrival and departure of the stator units in individual motors via analysis of high-resolution recordings of motor speed, while dynamically varying the load on the motor via external magnetic torque. The kinetic rates obtained, robust with respect to the details of the applied adsorption model, indicate that the lifetime of an assembled stator unit increases when a higher force is applied to its anchoring point in the cell wall. This provides strong evidence that a catch bond (a bond strengthened instead of weakened by force) drives mechanosensitivity of the flagellar motor complex. These results add the BFM to a short, but growing, list of systems demonstrating catch bonds, suggesting that this "molecular strategy" is a widespread mechanism to sense and respond to mechanical stress. We propose that force-enhanced stator adhesion allows the cell to adapt to a heterogeneous environmental viscosity and may ultimately play a role in surface-sensing during swarming and biofilm formation. PMID- 29183971 TI - Inequality in nature and society. AB - Most societies are economically dominated by a small elite, and similarly, natural communities are typically dominated by a small fraction of the species. Here we reveal a strong similarity between patterns of inequality in nature and society, hinting at fundamental unifying mechanisms. We show that chance alone will drive 1% or less of the community to dominate 50% of all resources in situations where gains and losses are multiplicative, as in returns on assets or growth rates of populations. Key mechanisms that counteract such hyperdominance include natural enemies in nature and wealth-equalizing institutions in society. However, historical research of European developments over the past millennium suggests that such institutions become ineffective in times of societal upscaling. A corollary is that in a globalizing world, wealth will inevitably be appropriated by a very small fraction of the population unless effective wealth equalizing institutions emerge at the global level.

However, crossover events are relatively rare, typically one to three exchange points per chromosome pair. Recent work has identified three pathways limiting meiotic crossovers in Arabidopsis thaliana that rely on the activity of FANCM [Crismani W, et al. (2012) Science 336:1588-1590], RECQ4 [Seguela-Arnaud M, et al. (2015) Proc Natl Acad Sci USA 112:4713-4718], and FIGL1 [Girard C, et al. (2015) PLoS Genet 11:e1005369]. Here we analyzed recombination in plants in which one, two, or all three of these pathways were disrupted in both pure line and hybrid contexts. The greatest effect was observed when combining recq4 and figl1 mutations, which increased the hybrid genetic map length from 389 to 3,037 cM. This corresponds to an unprecedented 7.8-fold increase in crossover frequency. Disrupting the three pathways did not further increase recombination, suggesting that some upper limit had been reached. The increase in crossovers is not uniform along chromosomes and rises from centromere to telomere. Finally, although in wild type recombination is much higher in male meiosis than in female meiosis (490 cM vs. 290 cM), female recombination is higher than male recombination in recq4 figl1 (3,200 cM vs. 2,720 cM), suggesting that the factors that make wild type female meiosis less recombinogenic than male wild-type meiosis do not apply in the mutant context. The massive increase in recombination observed in recq4 figl1 hybrids opens the possibility of manipulating recombination to enhance plant breeding efficiency.

AB - Patterns of interacting amino acids are so preserved within protein families that the sole analysis of evolutionary comutations can identify pairs of contacting residues. It is also known that evolution conserves functional dynamics, i.e., the concerted motion or displacement of large protein regions or domains. Is it, therefore, possible to use a pure sequence-based analysis to identify these dynamical domains? To address this question, we introduce here a general coevolutionary coupling analysis strategy and apply it to a curated sequence database of hundreds of protein families. For most families, the sequence-based method partitions amino acids into a few clusters. When viewed in the context of the native structure, these clusters have the signature characteristics of viable protein domains: They are spatially separated but individually compact. They have a direct functional bearing too, as shown for various reference cases. We conclude that even large-scale structural and functionally related properties can be recovered from inference methods applied to evolutionary-related sequences. The method introduced here is available as a software package and web server (spectrus.sissa.it/spectrus-evo_webserver). PMID- 29183973 TI - On the role of the corpus callosum in interhemispheric functional connectivity in humans. AB - Resting state functional connectivity is defined in terms of temporal correlations between physiologic signals, most commonly studied using functional magnetic resonance imaging. Major features of functional connectivity correspond to structural (axonal) connectivity. However, this relation is not one-to-one. Interhemispheric functional connectivity in relation to the corpus callosum presents a case in point. Specifically, several reports have documented nearly intact interhemispheric functional connectivity in individuals in whom the corpus callosum (the major commissure between the hemispheres) never develops. To investigate this question, we assessed functional connectivity before and after surgical section of the corpus callosum in 22 patients with medically refractory epilepsy. Section of the corpus callosum markedly reduced interhemispheric functional connectivity. This effect was more profound in multimodal associative areas in the frontal and parietal lobe than primary regions of sensorimotor and visual function. Moreover, no evidence of recovery was observed in a limited sample in which multiyear, longitudinal follow-up was obtained. Comparison of partial vs. complete callosotomy revealed several effects implying the existence of polysynaptic functional connectivity between remote brain regions. Thus, our results demonstrate that callosal as well as extracallosal anatomical connections play a role in the maintenance of interhemispheric functional connectivity. PMID- 29183974 TI - Spin susceptibility of charge-ordered YBa2Cu3O y across the upper critical field. AB - The value of the upper critical field Hc2, a fundamental characteristic of the superconducting state, has been subject to strong controversy in high-Tc copper oxides. Since the issue has been tackled almost exclusively by macroscopic techniques so far, there is a clear need for local-probe measurements. Here, we use 17O NMR to measure the spin susceptibility [Formula: see text] of the CuO2 planes at low temperature in charge-ordered YBa2Cu3O y We find that [Formula: see text] increases (most likely linearly) with magnetic field H and saturates above field values ranging from 20 T to 40 T. This result is consistent with the lowest Hc2 values claimed previously and with the interpretation that the charge density wave (CDW) reduces Hc2 in underdoped YBa2Cu3O y Furthermore, the absence of marked deviation in [Formula: see text] at the onset of long-range CDW order indicates that this [Formula: see text] reduction and the Fermi-surface reconstruction are primarily rooted in the short-range CDW order already present in zero field, not in the field-induced long-range CDW order. Above [Formula: see text], the relatively low values of [Formula: see text] at [Formula: see text] K show that the pseudogap is a ground-state property, independent of the superconducting gap. PMID- 29183975 TI - High-resolution mapping of cis-regulatory variation in budding yeast. AB - Genetic variants affecting gene-expression levels are a major source of phenotypic variation. The approximate locations of these variants can be mapped as expression quantitative trait loci (eQTLs); however, a major limitation of eQTLs is their low resolution, which precludes investigation of the causal variants and their molecular mechanisms. Here we report RNA-seq and full genome sequences for 85 diverse isolates of the yeast Saccharomyces cerevisiae-including wild, domesticated, and human clinical strains-which allowed us to perform eQTL mapping with 50-fold higher resolution than previously possible. In addition to variants in promoters, we uncovered an important role for variants in 3'UTRs, especially those affecting binding of the PUF family of RNA-binding proteins. The eQTLs are predominantly under negative selection, particularly those affecting essential genes and conserved genes. However, applying the sign test for lineage specific selection revealed the polygenic up-regulation of dozens of biofilm suppressor genes in strains isolated from human patients, consistent with the key role of biofilms in fungal pathogenicity. In addition, a single variant in the promoter of a biofilm suppressor, NIT3, showed the strongest genome-wide association with clinical origin. Altogether, our results demonstrate the power of high-resolution eQTL mapping in understanding the molecular mechanisms of regulatory variation, as well as the natural selection acting on this variation that drives adaptation to environments, ranging from laboratories to vineyards to the human body. PMID- 29183976 TI - Rapid adaptive evolution in novel environments acts as an architect of population range expansion. AB - Colonization and expansion into novel landscapes determine the distribution and abundance of species in our rapidly changing ecosystems worldwide. Colonization events are crucibles for rapid evolution, but it is not known whether evolutionary changes arise mainly after successful colonization has occurred, or if evolution plays an immediate role, governing the growth and expansion speed of colonizing populations. There is evidence that spatial evolutionary processes can speed range expansion within a few generations because dispersal tendencies may evolve upwards at range edges. Additionally, rapid adaptation to a novel environment can increase population growth rates, which also promotes spread. However, the role of adaptive evolution and the relative contributions of spatial evolution and adaptation to expansion are unclear. Using a model system, red flour beetles (Tribolium castaneum), we either allowed or constrained evolution of populations colonizing a novel environment and measured population growth and spread. At the end of the experiment we assessed the fitness and dispersal tendency of individuals originating either from the core or edge of evolving populations or from nonevolving populations in a common garden. Within six generations, evolving populations grew three times larger and spread 46% faster than populations in which evolution was constrained. Increased size and expansion speed were strongly driven by adaptation, whereas spatial evolutionary processes acting on edge subpopulations contributed less. This experimental evidence demonstrates that rapid evolution drives both population growth and expansion speed and is thus crucial to consider for managing biological invasions and successfully introducing or reintroducing species for management and conservation. PMID- 29183977 TI - Osmosensing by the bacterial PhoQ/PhoP two-component system. AB - The PhoQ/PhoP two-component system plays an essential role in the response of enterobacteria to the environment of their mammalian hosts. It is known to sense several stimuli that are potentially associated with the host, including extracellular magnesium limitation, low pH, and the presence of cationic antimicrobial peptides. Here, we show that the PhoQ/PhoP two-component systems of Escherichia coli and Salmonella can also perceive an osmotic upshift, another key stimulus to which bacteria become exposed within the host. In contrast to most previously established stimuli of PhoQ, the detection of osmotic upshift does not require its periplasmic sensor domain. Instead, we show that the activity of PhoQ is affected by the length of the transmembrane (TM) helix as well as by membrane lateral pressure. We therefore propose that osmosensing relies on a conformational change within the TM domain of PhoQ induced by a perturbation in cell membrane thickness and lateral pressure under hyperosmotic conditions. Furthermore, the response mediated by the PhoQ/PhoP two-component system was found to improve bacterial growth recovery under hyperosmotic stress, partly through stabilization of the sigma factor RpoS. Our findings directly link the PhoQ/PhoP two-component system to bacterial osmosensing, suggesting that this system can mediate a concerted response to most of the established host-related cues. PMID- 29183978 TI - Proteomics of phosphorylation and protein dynamics during fertilization and meiotic exit in the Xenopus egg. AB - Fertilization releases the meiotic arrest and initiates the events that prepare the egg for the ensuing developmental program. Protein degradation and phosphorylation are known to regulate protein activity during this process. However, the full extent of protein loss and phosphoregulation is still unknown. We examined absolute protein and phosphosite dynamics of the fertilization response by mass spectrometry-based proteomics in electroactivated eggs. To do this, we developed an approach for calculating the stoichiometry of phosphosites from multiplexed proteomics that is compatible with dynamic, stable, and multisite phosphorylation. Overall, the data suggest that degradation is limited to a few low-abundance proteins. However, this degradation promotes extensive dephosphorylation that occurs over a wide range of abundances during meiotic exit. We also show that eggs release a large amount of protein into the medium just after fertilization, most likely related to the blocks to polyspermy. Concomitantly, there is a substantial increase in phosphorylation likely tied to calcium-activated kinases. We identify putative degradation targets and components of the slow block to polyspermy. The analytical approaches demonstrated here are broadly applicable to studies of dynamic biological systems. PMID- 29183979 TI - Vasopressin excites interneurons to suppress hippocampal network activity across a broad span of brain maturity at birth. AB - During birth in mammals, a pronounced surge of fetal peripheral stress hormones takes place to promote survival in the transition to the extrauterine environment. However, it is not known whether the hormonal signaling involves central pathways with direct protective effects on the perinatal brain. Here, we show that arginine vasopressin specifically activates interneurons to suppress spontaneous network events in the perinatal hippocampus. Experiments done on the altricial rat and precocial guinea pig neonate demonstrated that the effect of vasopressin is not dependent on the level of maturation (depolarizing vs. hyperpolarizing) of postsynaptic GABAA receptor actions. Thus, the fetal mammalian brain is equipped with an evolutionarily conserved mechanism well suited to suppress energetically expensive correlated network events under conditions of reduced oxygen supply at birth. PMID- 29183980 TI - Speaker gaze increases information coupling between infant and adult brains. AB - When infants and adults communicate, they exchange social signals of availability and communicative intention such as eye gaze. Previous research indicates that when communication is successful, close temporal dependencies arise between adult speakers' and listeners' neural activity. However, it is not known whether similar neural contingencies exist within adult-infant dyads. Here, we used dual electroencephalography to assess whether direct gaze increases neural coupling between adults and infants during screen-based and live interactions. In experiment 1 (n = 17), infants viewed videos of an adult who was singing nursery rhymes with (i) direct gaze (looking forward), (ii) indirect gaze (head and eyes averted by 20 degrees ), or (iii) direct-oblique gaze (head averted but eyes orientated forward). In experiment 2 (n = 19), infants viewed the same adult in a live context, singing with direct or indirect gaze. Gaze-related changes in adult infant neural network connectivity were measured using partial directed coherence. Across both experiments, the adult had a significant (Granger) causal influence on infants' neural activity, which was stronger during direct and direct-oblique gaze relative to indirect gaze. During live interactions, infants also influenced the adult more during direct than indirect gaze. Further, infants vocalized more frequently during live direct gaze, and individual infants who vocalized longer also elicited stronger synchronization from the adult. These results demonstrate that direct gaze strengthens bidirectional adult-infant neural connectivity during communication. Thus, ostensive social signals could act to bring brains into mutual temporal alignment, creating a joint-networked state that is structured to facilitate information transfer during early communication and learning. PMID- 29183981 TI - Robust zero resistance in a superconducting high-entropy alloy at pressures up to 190 GPa. AB - We report the observation of extraordinarily robust zero-resistance superconductivity in the pressurized (TaNb)0.67(HfZrTi)0.33 high-entropy alloy--a material with a body-centered-cubic crystal structure made from five randomly distributed transition-metal elements. The transition to superconductivity (TC ) increases from an initial temperature of 7.7 K at ambient pressure to 10 K at ~60 GPa, and then slowly decreases to 9 K by 190.6 GPa, a pressure that falls within that of the outer core of the earth. We infer that the continuous existence of the zero-resistance superconductivity from 1 atm up to such a high pressure requires a special combination of electronic and mechanical characteristics. This high-entropy alloy superconductor thus may have a bright future for applications under extreme conditions, and also poses a challenge for understanding the underlying quantum physics. PMID- 29183982 TI - Improved detection of synthetic lethal interactions in Drosophila cells using variable dose analysis (VDA). AB - Synthetic sick or synthetic lethal (SS/L) screens are a powerful way to identify candidate drug targets to specifically kill tumor cells, but this approach generally suffers from low consistency between screens. We found that many SS/L interactions involve essential genes and are therefore detectable within a limited range of knockdown efficiency. Such interactions are often missed by overly efficient RNAi reagents. We therefore developed an assay that measures viability over a range of knockdown efficiency within a cell population. This method, called Variable Dose Analysis (VDA), is highly sensitive to viability phenotypes and reproducibly detects SS/L interactions. We applied the VDA method to search for SS/L interactions with TSC1 and TSC2, the two tumor suppressors underlying tuberous sclerosis complex (TSC), and generated a SS/L network for TSC. Using this network, we identified four Food and Drug Administration-approved drugs that selectively affect viability of TSC-deficient cells, representing promising candidates for repurposing to treat TSC-related tumors. PMID- 29183983 TI - Precision genome editing using synthesis-dependent repair of Cas9-induced DNA breaks. AB - The RNA-guided DNA endonuclease Cas9 has emerged as a powerful tool for genome engineering. Cas9 creates targeted double-stranded breaks (DSBs) in the genome. Knockin of specific mutations (precision genome editing) requires homology directed repair (HDR) of the DSB by synthetic donor DNAs containing the desired edits, but HDR has been reported to be variably efficient. Here, we report that linear DNAs (single and double stranded) engage in a high-efficiency HDR mechanism that requires only ~35 nucleotides of homology with the targeted locus to introduce edits ranging from 1 to 1,000 nucleotides. We demonstrate the utility of linear donors by introducing fluorescent protein tags in human cells and mouse embryos using PCR fragments. We find that repair is local, polarity sensitive, and prone to template switching, characteristics that are consistent with gene conversion by synthesis-dependent strand annealing. Our findings enable rational design of synthetic donor DNAs for efficient genome editing. PMID- 29183984 TI - Unraveling the structure and chemical mechanisms of highly oxygenated intermediates in oxidation of organic compounds. AB - Decades of research on the autooxidation of organic compounds have provided fundamental and practical insights into these processes; however, the structure of many key autooxidation intermediates and the reactions leading to their formation still remain unclear. This work provides additional experimental evidence that highly oxygenated intermediates with one or more hydroperoxy groups are prevalent in the autooxidation of various oxygenated (e.g., alcohol, aldehyde, keto compounds, ether, and ester) and nonoxygenated (e.g., normal alkane, branched alkane, and cycloalkane) organic compounds. These findings improve our understanding of autooxidation reaction mechanisms that are routinely used to predict fuel ignition and oxidative stability of liquid hydrocarbons, while also providing insights relevant to the formation mechanisms of tropospheric aerosol building blocks. The direct observation of highly oxygenated intermediates for the autooxidation of alkanes at 500-600 K builds upon prior observations made in atmospheric conditions for the autooxidation of terpenes and other unsaturated hydrocarbons; it shows that highly oxygenated intermediates are stable at conditions above room temperature. These results further reveal that highly oxygenated intermediates are not only accessible by chemical activation but also by thermal activation. Theoretical calculations on H-atom migration reactions are presented to rationalize the relationship between the organic compound's molecular structure (n-alkane, branched alkane, and cycloalkane) and its propensity to produce highly oxygenated intermediates via extensive autooxidation of hydroperoxyalkylperoxy radicals. Finally, detailed chemical kinetic simulations demonstrate the influence of these additional reaction pathways on the ignition of practical fuels.

PMID- 29183987 TI - SpotLearn: Convolutional Neural Network for Detection of Fluorescence In Situ Hybridization (FISH) Signals in High-Throughput Imaging Approaches. AB - DNA fluorescence in situ hybridization (FISH) is the technique of choice to map the position of genomic loci in three-dimensional (3D) space at the single allele level in the cell nucleus. High-throughput DNA FISH methods have recently been developed using complex libraries of fluorescently labeled synthetic oligonucleotides and automated fluorescence microscopy, enabling large-scale interrogation of genomic organization. Although the FISH signals generated by high-throughput methods can, in principle, be analyzed by traditional spot detection algorithms, these approaches require user intervention to optimize each interrogated genomic locus, making analysis of tens or hundreds of genomic loci in a single experiment prohibitive. We report here the design and testing of two separate machine learning-based workflows for FISH signal detection in a high throughput format. The two methods rely on random forest (RF) classification or convolutional neural networks (CNNs), respectively. Both workflows detect DNA FISH signals with high accuracy in three separate fluorescence microscopy channels for tens of independent genomic loci, without the need for manual parameter value setting on a per locus basis. In particular, the CNN workflow, which we named SpotLearn, is highly efficient and accurate in the detection of DNA FISH signals with low signal-to-noise ratio (SNR). We suggest that SpotLearn will be useful to accurately and robustly detect diverse DNA FISH signals in a high-throughput fashion, enabling the visualization and positioning of hundreds of genomic loci in a single experiment. PMID- 29183985 TI - Metagenomics-guided analysis of microbial chemolithoautotrophic phosphite oxidation yields evidence of a seventh natural CO2 fixation pathway. AB - Dissimilatory phosphite oxidation (DPO), a microbial metabolism by which phosphite (HPO32-) is oxidized to phosphate (PO43-), is the most energetically favorable chemotrophic electron-donating process known. Only one DPO organism has been described to date, and little is known about the environmental relevance of this metabolism. In this study, we used 16S rRNA gene community analysis and genome-resolved metagenomics to characterize anaerobic wastewater treatment sludge enrichments performing DPO coupled to CO2 reduction. We identified an uncultivated DPO bacterium, Candidatus Phosphitivorax (Ca. P.) anaerolimi strain Phox-21, that belongs to candidate order GW-28 within the Deltaproteobacteria, which has no known cultured isolates. Genes for phosphite oxidation and for CO2 reduction to formate were found in the genome of Ca. P. anaerolimi, but it appears to lack any of the known natural carbon fixation pathways. These observations led us to propose a metabolic model for autotrophic growth by Ca. P. anaerolimi whereby DPO drives CO2 reduction to formate, which is then assimilated into biomass via the reductive glycine pathway. PMID- 29183988 TI - Development and differentiation of early innate lymphoid progenitors. AB - Early innate lymphoid progenitors (EILPs) have recently been identified in mouse adult bone marrow as a multipotential progenitor population specified toward innate lymphoid cell (ILC) lineages, but their relationship with other described ILC progenitors is still unclear. In this study, we examine the progenitor successor relationships between EILPs, all-lymphoid progenitors (ALPs), and ILC precursors (ILCps). Functional, bioinformatic, phenotypical, and genetic approaches collectively establish EILPs as an intermediate progenitor between ALPs and ILCps. Our work additionally provides new candidate regulators of ILC development and clearly defines the stage of requirement of transcription factors key for early ILC development.

PMID- 29183992 TI - Structural basis for the recognition of kinesin family member 21A (KIF21A) by the ankyrin domains of KANK1 and KANK2 proteins. AB - A well-controlled microtubule organization is essential for intracellular transport, cytoskeleton maintenance, and cell development. KN motif and ankyrin repeat domain-containing protein 1 (KANK1), a member of KANK family, recruits kinesin family member 21A (KIF21A) to the cell cortex to control microtubule growth via its C-terminal ankyrin domain. However, how the KANK1 ankyrin domain recognizes KIF21A and whether other KANK proteins can also bind KIF21A remain unknown. Here, using a combination of structural, site-directed mutagenesis, and biochemical studies, we found that a stretch of ~22 amino acids in KIF21A is sufficient for binding to KANK1 and its close homolog KANK2. We further solved the complex structure of the KIF21A peptide with either the KANK1 ankyrin domain or the KANK2 ankyrin domain. In each complex, KIF21A is recognized by two distinct pockets of the ankyrin domain and adopts helical conformations upon binding to the ankyrin domain. The elucidated KANK structures may advance our understanding of the role of KANK1 as a scaffolding molecule in controlling microtubule growth at the cell periphery. PMID- 29183993 TI - Failed mitochondrial import and impaired proteostasis trigger SUMOylation of mitochondrial proteins. AB - Modification by the ubiquitin-like protein SUMO affects hundreds of cellular substrate proteins and regulates a wide variety of physiological processes. While the SUMO system appears to predominantly target nuclear proteins and, to a lesser extent, cytosolic proteins, hardly anything is known about the SUMOylation of proteins targeted to membrane-enclosed organelles. Here, we identify a large set of structurally and functionally unrelated mitochondrial proteins as substrates of the SUMO pathway in yeast. We show that SUMO modification of mitochondrial proteins does not rely on mitochondrial targeting and, in fact, is strongly enhanced upon import failure, consistent with the modification occurring in the cytosol. Moreover, SUMOylated forms of mitochondrial proteins particularly accumulate in HSP70- and proteasome-deficient cells, suggesting that SUMOylation participates in cellular protein quality control. We therefore propose that SUMO serves as a mark for nonfunctional mitochondrial proteins, which only sporadically arise in unstressed cells but strongly accumulate upon defective mitochondrial import and impaired proteostasis. Overall, our findings provide support for a role of SUMO in the cytosolic response to aberrant proteins. PMID- 29183994 TI - Translation efficiency is maintained at elevated temperature in Escherichia coli. AB - Cellular protein levels are dictated by the balance between gene transcription, mRNA translation, and protein degradation, among other factors. Translation requires the interplay of several RNA hybridization processes, which are expected to be temperature-sensitive. We used ribosome profiling to monitor translation in Escherichia coli at 30 degrees C and to investigate how this changes after 10-20 min of heat shock at 42 degrees C. Translation efficiencies are robustly maintained after thermal heat shock and after mimicking the heat-shock response transcriptional program at 30 degrees C by overexpressing the heat shock sigma factor encoded by the rpoH gene. We compared translation efficiency, the ratio of ribosome footprint reads to mRNA reads for each gene, to parameters derived from gene sequences. Genes with stable mRNA structures, non-optimal codon use, and those whose gene product is cotranslationally translocated into the inner membrane are generally less highly translated than other genes. Comparison with other published datasets suggests a role for translational elongation in coupling mRNA structures to translation initiation. Genome-wide calculations of the temperature dependence of mRNA structure predict that relatively few mRNAs show a melting transition between 30 and 42 degrees C, consistent with the observed lack of changes in translation efficiency. We developed a linear model with six parameters that can predict 38% of the variation in translation efficiency between genes, which may be useful in interpreting transcriptome data. PMID- 29183995 TI - Deubiquitylase USP9X suppresses tumorigenesis by stabilizing large tumor suppressor kinase 2 (LATS2) in the Hippo pathway. AB - The Hippo pathway plays important roles in controlling organ size and in suppressing tumorigenesis through large tumor suppressor kinase 1/2 (LATS1/2) mediated phosphorylation of YAP/TAZ transcription co-activators. The kinase activity of LATS1/2 is regulated by phosphorylation in response to extracellular signals. Moreover, LATS2 protein levels are repressed by the ubiquitin-proteasome system in conditions such as hypoxia. However, the mechanism that removes the ubiquitin modification from LATS2 and thereby stabilizes the protein is not well understood. Here, using tandem affinity purification (TAP), we found that anaphase-promoting complex/cyclosome (APC/C), a ubiquitin ligase complex, and USP9X, a deubiquitylase, specifically interact with LATS2. We also found that although APC1 co-localizes with LATS2 to intracellular vesicle structures, it does not regulate LATS2 protein levels and activity. In contrast, USP9X ablation drastically diminished LATS2 protein levels. We further demonstrated that USP9X deubiquitinates LATS2 and thus prevents LATS2 degradation by the proteasome. Furthermore, in pancreatic cancer cells, USP9X loss activated YAP and enhanced the oncogenic potential of the cells. In addition, the tumorigenesis induced by the USP9X ablation depended not only on LATS2 repression, but also on YAP/TAZ activity. We conclude that USP9X is a deubiquitylase of the Hippo pathway kinase LATS2 and that the Hippo pathway functions as a downstream signaling cascade that mediates USP9X's tumor-suppressive activity. PMID- 29183996 TI - Structural characterization of the bacterial proteasome homolog BPH reveals a tetradecameric double-ring complex with unique inner cavity properties. AB - Eukaryotic and archaeal proteasomes are paradigms for self-compartmentalizing proteases. To a large extent, their function requires interplay with hexameric ATPases associated with diverse cellular activities (AAA+) that act as substrate unfoldases. Bacteria have various types of self-compartmentalizing proteases; in addition to the proteasome itself, these include the proteasome homolog HslV, which functions together with the AAA+ HslU; the ClpP protease with its partner AAA+ ClpX; and Anbu, a recently characterized ancestral proteasome variant. Previous bioinformatic analysis has revealed a novel bacterial member of the proteasome family Betaproteobacteria proteasome homolog (BPH). Using cluster analysis, we here affirmed that BPH evolutionarily descends from HslV. Crystal structures of the Thiobacillus denitrificans and Cupriavidus metallidurans BPHs disclosed a homo-oligomeric double-ring architecture in which the active sites face the interior of the cylinder. Using small-angle X-ray scattering (SAXS) and electron microscopy averaging, we found that BPH forms tetradecamers in solution, unlike the dodecamers seen in HslV. Although the highly acidic inner surface of BPH was in striking contrast to the cavity characteristics of the proteasome and HslV, a classical proteasomal reaction mechanism could be inferred from the covalent binding of the proteasome-specific inhibitor epoxomicin to BPH. A ligand bound structure implied that the elongated BPH inner pore loop may be involved in substrate recognition. The apparent lack of a partner unfoldase and other unique features, such as Ser replacing Thr as the catalytic residue in certain BPH subfamilies, suggest a proteolytic function for BPH distinct from those of known bacterial self-compartmentalizing proteases. PMID- 29183997 TI - Hyaluronan content governs tissue stiffness in pancreatic islet inflammation. AB - We have identified a novel role for hyaluronan (HA), an extracellular matrix polymer, in governing the mechanical properties of inflamed tissues. We recently reported that insulitis in type 1 diabetes of mice and humans is preceded by intraislet accumulation of HA, a highly hygroscopic polymer. Using the double transgenic DO11.10 * RIPmOVA (DORmO) mouse model of type 1 diabetes, we asked whether autoimmune insulitis was associated with changes in the stiffness of islets. To measure islet stiffness, we used atomic force microscopy (AFM) and developed a novel "bed of nails"-like approach that uses quartz glass nanopillars to anchor islets, solving a long-standing problem of keeping tissue-scale objects immobilized while performing AFM. We measured stiffness via AFM nanoindentation with a spherical indenter and found that insulitis made islets mechanically soft compared with controls. Conversely, treatment with 4-methylumbelliferone, a small molecule inhibitor of HA synthesis, reduced HA accumulation, diminished swelling, and restored basal tissue stiffness. These results indicate that HA content governs the mechanical properties of islets. In hydrogels with variable HA content, we confirmed that increased HA leads to mechanically softer hydrogels, consistent with our model. In light of recent reports that the insulin production of islets is mechanosensitive, these findings open up an exciting new avenue of research into the fundamental mechanisms by which inflammation impacts local cellular responses. PMID- 29183998 TI - Chondroitin sulfate-mediated N-cadherin/beta-catenin signaling is associated with basal-like breast cancer cell invasion. AB - Tumor metastasis involves cancer cell invasion across basement membranes and interstitial tissues. The initial invasion step consists of adherence of the tumor cell to the extracellular matrix (ECM), and this binding transduces a variety of signals from the ECM to the tumor cell. Accordingly, it is critical to establish the mechanisms by which extracellular cues influence the intracellular activities that regulate tumor cell invasion. Here, we found that invasion of the basal-like breast cancer cell line BT-549 is enhanced by the ECM component chondroitin sulfates (CSs). CSs interacted with and induced proteolytic cleavage of N-cadherin in the BT-549 cells, yielding a C-terminal intracellular N-cadherin fragment that formed a complex with beta-catenin. Of note, the cleavage of N cadherin increased cytoplasmic and nuclear beta-catenin levels; induced the matrix metalloproteinase 9 (MMP9) gene, a target of beta-catenin nuclear signaling; and augmented the invasion potential of the cells. We also found that CS-induced N-cadherin proteolysis requires caveolae-mediated endocytosis. An inhibitor of that process, nystatin, blocked both the endocytosis and proteolytic cleavage of N-cadherin induced by CS and also suppressed BT-549 cell invasion. Knock-out of chondroitin 4-O-sulfotransferase-1 (C4ST-1), a key CS biosynthetic enzyme, suppressed activation of the N-cadherin/beta-catenin pathway through N cadherin endocytosis and significantly decreased BT-549 cell invasion. These results suggest that CSs produced by C4ST-1 might be useful therapeutic targets in the management of basal-like breast cancers. PMID- 29183999 TI - Autopolysialylation of polysialyltransferases is required for polysialylation and polysialic acid chain elongation on select glycoprotein substrates. AB - Polysialic acid (polySia) is a large glycan polymer that is added to some glycoproteins by two polysialyltransferases (polySTs), ST8Sia-II and ST8Sia-IV. As polySia modulates cell adhesion and signaling, immune cell function, and tumor metastasis, it is of interest to determine how the polySTs recognize their select substrates. We have recently identified residues within the ST8Sia-IV polybasic region (PBR) that are required for neural cell adhesion molecule (NCAM) recognition and subsequent polysialylation. Here, we compared the PBR sequence requirements for NCAM, neuropilin-2 (NRP-2), and synaptic cell adhesion molecule 1 (SynCAM 1) for polysialylation by their respective polySTs. We found that the polySTs use unique but overlapping sets of PBR residues for substrate recognition, that the NCAM-recognizing PBR sites in ST8Sia-II and ST8Sia-IV include homologous residues, but that the ST8Sia-II site is larger, and that fewer PBR residues are involved in NRP-2 and SynCAM 1 recognition than in NCAM recognition. Noting that the two sites for ST8Sia-IV autopolysialylation flank the PBR, we evaluated the role of PBR residues in autopolysialylation and found that the requirements for polyST autopolysialylation and substrate polysialylation overlap. These data together with the evaluation of the polyST autopolysialylation mechanism enabled us to further identify PBR residues potentially playing dual roles in substrate recognition and in polySia chain polymerization. Finally, we found that ST8Sia-IV autopolysialylation is required for NRP-2 polysialylation and that ST8Sia-II autopolysialylation promotes the polymerization of longer polySia chains on SynCAM 1, suggesting a critical role for polyST autopolysialylation in substrate selection and polySia chain elongation.

AB - The islet-specific zinc transporter ZnT8 is a major self-antigen found in insulin granules of pancreatic beta-cells. Frequent insulin secretion exposes ZnT8 to the cell surface, but the humoral antigenicity of the surface-displayed ZnT8 remains unknown. Here we show that a membrane-embedded human ZnT8 antigen triggered a vigorous immune response in ZnT8 knock-out mice. Approximately 50% of serum immunoreactivities toward ZnT8 were mapped to its transmembrane domain that is accessible to extracellular ZnT8 antibody (ZnT8A). ZnT8A binding was detected on live rat insulinoma INS-1E cells, and the binding specificity was validated by a CRISPR/Cas9 mediated ZnT8 knock-out. Applying established ZnT8A assays to purified serum antibodies from patients with type 1 diabetes, we detected human ZnT8A bound to live INS-1E cells, whereas a ZnT8 knock-out specifically reduced the surface binding. Our results demonstrate that ZnT8 is a cell surface self antigen, raising the possibility of a direct involvement in antibody-mediated beta-cell dysfunction and cytotoxicity.

PMID- 29184002 TI - A guanine nucleotide exchange factor (GEF) limits Rab GTPase-driven membrane fusion. AB - The identity of organelles in the endomembrane system of any eukaryotic cell critically depends on the correctly localized Rab GTPase, which binds effectors and thus promotes membrane remodeling or fusion. However, it is still unresolved which factors are required and therefore define the localization of the correct fusion machinery. Using SNARE-decorated proteoliposomes that cannot fuse on their own, we now demonstrate that full fusion activity can be achieved by just four soluble factors: a soluble SNARE (Vam7), a guanine nucleotide exchange factor (GEF, Mon1-Ccz1), a Rab-GDP dissociation inhibitor (GDI) complex (prenylated Ypt7 GDI), and a Rab effector complex (HOPS). Our findings reveal that the GEF Mon1 Ccz1 is necessary and sufficient for stabilizing prenylated Ypt7 on membranes. HOPS binding to Ypt7-GTP then drives SNARE-mediated fusion, which is fully GTP dependent. We conclude that an entire fusion cascade can be controlled by a GEF. PMID- 29184003 TI - IL-10 promoter transactivation by the viral K-RTA protein involves the host-cell transcription factors, specificity proteins 1 and 3. AB - Kaposi's sarcoma-associated herpesvirus (KSHV)/human herpesvirus-8 (HHV-8) causes a persistent infection, presenting latent and lytic replication phases during its life cycle. KSHV-related diseases are associated with deregulated expression of inflammatory cytokines, including IL-6 and IL-10, but the mechanisms underlying this dysregulation are unclear. Herein, we report a molecular mechanism for KSHV induced IL-10 gene expression. KSHV replication and transcription activator (K RTA) is a molecular switch for the initiation of expression of viral lytic genes, and we describe, for the first time, that K-RTA significantly activates the promoter of the human IL-10 gene. Of note, mutations involving a basic region of K-RTA reduced the association of K-RTA with the IL-10 promoter. Moreover, the host-cell transcription factors, specificity proteins (SP) 1 and 3, play a pivotal cooperative role in K-RTA-mediated transactivation of the IL-10 promoter. K-RTA can interact with SP1 and SP3 directly in vitro, and electrophoresis mobility shift assays (EMSAs) revealed co-operative interaction involving K-RTA, SP1, and SP3 in binding to the IL-10 promoter. As DNase I footprinting assays indicated that K-RTA did not affect SP3 binding to the IL-10 promoter, SP3 can function to recruit K-RTA to the IL-10 promoter. These findings indicate that K RTA can directly contribute to IL-10 up-regulation via a functional interplay with the cellular transcription factors SP1 and SP3. PMID- 29184005 TI - An infant with congenital rubella syndrome in developing India. AB - Congenital rubella syndrome (CRS), caused by rubella virus infection during pregnancy, remains a public health concern in developing countries. Three to five per cent of all suspected CRS cases in India have been proven to be a rubella infection. Only about 45%-60% of pregnant women and infants in India receive the rubella vaccination. We present a case of a preterm female infant who tested positive for the rubella virus. The baby was born with low birth weight and, on examination, showed pallor and hepatosplenomegaly. She was detected to have an ostium secundum atrial septal defect (ASD) and a large patent ductus arteriosus (PDA) on echocardiography. On ophthalmic examination, she was diagnosed with bilateral cataract. She was treated with diuretics, and she underwent surgical correction for PDA. With this case we intend to present the literature, clinical manifestations and management of CRS. We will also focus on prevention, vaccination and disease burden in India.?. PMID- 29184004 TI - A global view of structure-function relationships in the tautomerase superfamily. AB - The tautomerase superfamily (TSF) consists of more than 11,000 nonredundant sequences present throughout the biosphere. Characterized members have attracted much attention because of the unusual and key catalytic role of an N-terminal proline. These few characterized members catalyze a diverse range of chemical reactions, but the full scale of their chemical capabilities and biological functions remains unknown. To gain new insight into TSF structure-function relationships, we performed a global analysis of similarities across the entire superfamily and computed a sequence similarity network to guide classification into distinct subgroups. Our results indicate that TSF members are found in all domains of life, with most being present in bacteria. The eukaryotic members of the cis-3-chloroacrylic acid dehalogenase subgroup are limited to fungal species, whereas the macrophage migration inhibitory factor subgroup has wide eukaryotic representation (including mammals). Unexpectedly, we found that 346 TSF sequences lack Pro-1, of which 85% are present in the malonate semialdehyde decarboxylase subgroup. The computed network also enabled the identification of similarity paths, namely sequences that link functionally diverse subgroups and exhibit transitional structural features that may help explain reaction divergence. A structure-guided comparison of these linker proteins identified conserved transitions between them, and kinetic analysis paralleled these observations. Phylogenetic reconstruction of the linker set was consistent with these findings. Our results also suggest that contemporary TSF members may have evolved from a short 4-oxalocrotonate tautomerase-like ancestor followed by gene duplication and fusion. Our new linker-guided strategy can be used to enrich the discovery of sequence/structure/function transitions in other enzyme superfamilies. PMID- 29184006 TI - Pain improvement in Camurati-Engelmann disease after anti-TNFalpha therapy. AB - Camurati-Engelmann disease (CED) is a rare disorder included in the group of craniotubular hyperostosis diseases. Corticosteroids are used for pain management in CED, but in refractory or corticosteroid-non-tolerant patients, pain management is limited. We report the case of a woman with CED diagnosed in early infancy whose initial complaints included persistent bone pain associated with progressive functional disability. She was treated with steroids but over time became dependent on higher doses with only mild pain relief. In her third decade, she was diagnosed with ulcerative colitis (UC) and was treated with mesalazine, azathioprine and prednisolone. Due to recurrent exacerbations of UC, treatment was changed to infliximab, an antitumour necrosis factor-alpha (TNFalpha). Remission of UC was achieved and CED-associated pain also improved with infliximab. This is the first report showing a possible role of anti-TNFalpha in pain management in CED with unsatisfactory response to steroids.

However, such cases may be encountered in endemic areas. Here, we report a case of filariasis of breast in a 55-year-old woman who was clinically mistaken for inflammatory carcinoma of the breast. Sonomammography revealed classic signs pointing towards the diagnosis of filariasis of breast, which was confirmed with microscopic examination of fine needle aspirate. Thus, imaging played a pivotal role in correctly diagnosing and further altering the line of management. PMID- 29184009 TI - Disseminated hydatid cyst of liver and lung. AB - Hydatid cyst commonly affects liver followed by lung, but rarely affects both organs simultaneously. Here we presented a patient who presented with concurrent involvement of both lungs and liver. Patient presented with dyspnoea and generalised weakness with bilateral rounded opacities throughout the lung field of variable sizes. CT scan chest with contrast showed multiple rounded soft tissue density in both lungs and liver. Patient underwent mini thoracotomy which revealed multiple cystic lesions throughout lung. ELISA for anti-Echinococcus antibodies shows positive titres. Due to extensive involvement, patient was started on medical treatment albendazole. The patient showed significant improvement both clinically and radiographically on treatment. Thus long-term medical treatment helps in such cases where surgery is not possible. PMID- 29184010 TI - Delayed massive haemothorax 10 days following percutaneous nephrolithotomy. AB - A 56-year-old man presented with massive right haemothorax 10 days following percutaneous nephrolithotomy (PCNL) for complex, large-bulk, right renal stones. Antiplatelet medication started following coronary stenting 7 months ago was stopped 5 days prior and resumed 2 days following surgery. Stones were cleared through two tracts, one supracostal, with placement of ureteral stent but no nephrostomy. He was discharged the next day with an unremarkable chest X-ray. He developed cough and fever after 1 week. Three days later he presented with acute dyspnoea, blood pressure of 100/60 mm Hg, pulse of 120/min and haemoglobin of 9.0 g/dL. Chest X-ray and CT scan showed a large right haemothorax. Two-litre haemothorax was drained by intercostal drainage with prompt recovery. Haemothorax is a rare complication following PCNL usually after supracostal access. Most occur at or immediately following surgery. Infection and early resumption of antiplatelet medication might have contributed to his presentation with delayed secondary haemorrhage from a pleural injury.

PMID- 29184014 TI - Recipient-Biased Competition for an Intracellularly Generated Cross-Fed Nutrient Is Required for Coexistence of Microbial Mutualists. AB - Many mutualistic microbial relationships are based on nutrient cross-feeding. Traditionally, cross-feeding is viewed as being unidirectional, from the producer to the recipient. This is likely true when a producer's waste, such as a fermentation product, has value only for a recipient. However, in some cases the cross-fed nutrient holds value for both the producer and the recipient. In such cases, there is potential for nutrient reacquisition by producer cells in a population, leading to competition against recipients. Here, we investigated the consequences of interpartner competition for cross-fed nutrients on mutualism dynamics by using an anaerobic coculture pairing fermentative Escherichia coli and phototrophic Rhodopseudomonas palustris In this coculture, E. coli excretes waste organic acids that provide a carbon source for R. palustris In return, R. palustris cross-feeds E. coli ammonium (NH4+), a compound that both species value. To explore the potential for interpartner competition, we first used a kinetic model to simulate cocultures with varied affinities for NH4+ in each species. The model predicted that interpartner competition for NH4+ could profoundly impact population dynamics. We then experimentally tested the predictions by culturing mutants lacking NH4+ transporters in both NH4+ competition assays and mutualistic cocultures. Both theoretical and experimental results indicated that the recipient must have a competitive advantage in acquiring cross-fed NH4+ to sustain the mutualism. This recipient-biased competitive advantage is predicted to be crucial, particularly when the communally valuable nutrient is generated intracellularly. Thus, the very metabolites that form the basis for mutualistic cross-feeding can also be subject to competition between mutualistic partners.IMPORTANCE Mutualistic relationships, particularly those based on nutrient cross-feeding, promote stability of diverse ecosystems and drive global biogeochemical cycles. Cross-fed nutrients within these systems can be either waste products valued by only one partner or nutrients valued by both partners. Here, we explored how interpartner competition for a communally valuable cross-fed nutrient impacts mutualism dynamics. We discovered that mutualism stability necessitates that the recipient have a competitive advantage against the producer in obtaining the cross-fed nutrient, provided that the nutrient is generated intracellularly. We propose that the requirement for recipient-biased competition is a general rule for mutualistic coexistence based on the transfer of intracellularly generated, communally valuable resources. PMID- 29184015 TI - Molecular Basis of Bacterial Longevity. AB - It is well known that many bacteria can survive in a growth-arrested state for long periods of time, on the order of months or even years, without forming dormant structures like spores or cysts. How is such longevity possible? What is the molecular basis of such longevity? Here we used the Gram-negative phototrophic alphaproteobacterium Rhodopseudomonas palustris to identify molecular determinants of bacterial longevity. R. palustris maintained viability for over a month after growth arrest due to nutrient depletion when it was provided with light as a source of energy. In transposon sequencing (Tn-seq) experiments, we identified 117 genes that were required for long-term viability of nongrowing R. palustris cells. Genes in this longevity gene set are annotated to play roles in a number of cellular processes, including DNA repair, tRNA modification, and the fidelity of protein synthesis. These genes are critically important only when cells are not growing. Three genes annotated to affect translation or posttranslational modifications were validated as bona fide longevity genes by mutagenesis and complementation experiments. These genes and others in the longevity gene set are broadly conserved in bacteria. This raises the possibility that it will be possible to define a core set of longevity genes common to many bacterial species.IMPORTANCE Bacteria in nature and during infections often exist in a nongrowing quiescent state. However, it has been difficult to define experimentally the molecular characteristics of this crucial element of the bacterial life cycle because bacteria that are not growing tend to die under laboratory conditions. Here we present and validate the phototrophic bacterium Rhodopseudomonas palustris as a model system for identification of genes required for the longevity of nongrowing bacteria. Growth-arrested R. palustris maintained almost full viability for weeks using light as an energy source. Such cells were subjected to large-scale mutagenesis to identify genes required for this striking longevity trait. The results define conserved determinants of survival under nongrowing conditions and create a foundation for more extensive studies to elucidate general molecular mechanisms of bacterial longevity.

PMID- 29184017 TI - Vaccination with Recombinant Cryptococcus Proteins in Glucan Particles Protects Mice against Cryptococcosis in a Manner Dependent upon Mouse Strain and Cryptococcal Species. AB - Development of a vaccine to protect against cryptococcosis is a priority given the enormous global burden of disease in at-risk individuals. Using glucan particles (GPs) as a delivery system, we previously demonstrated that mice vaccinated with crude Cryptococcus-derived alkaline extracts were protected against lethal challenge with Cryptococcus neoformans and Cryptococcus gattii The goal of the present study was to identify protective protein antigens that could be used in a subunit vaccine. Using biased and unbiased approaches, six candidate antigens (Cda1, Cda2, Cda3, Fpd1, MP88, and Sod1) were selected, recombinantly expressed in Escherichia coli, purified, and loaded into GPs. Three mouse strains (C57BL/6, BALB/c, and DR4) were then vaccinated with the antigen-laden GPs, following which they received a pulmonary challenge with virulent C. neoformans and C. gattii strains. Four candidate vaccines (GP-Cda1, GP-Cda2, GP-Cda3, and GP Sod1) afforded a significant survival advantage in at least one mouse model; some vaccine combinations provided added protection over that seen with either antigen alone. Vaccine-mediated protection against C. neoformans did not necessarily predict protection against C. gattii Vaccinated mice developed pulmonary inflammatory responses that effectively contained the infection; many surviving mice developed sterilizing immunity. Predicted T helper cell epitopes differed between mouse strains and in the degree to which they matched epitopes predicted in humans. Thus, we have discovered cryptococcal proteins that make promising candidate vaccine antigens. Protection varied depending on the mouse strain and cryptococcal species, suggesting that a successful human subunit vaccine will need to contain multiple antigens, including ones that are species specific.IMPORTANCE The encapsulated fungi Cryptococcus neoformans and Cryptococcus gattii are responsible for nearly 200,000 deaths annually, mostly in immunocompromised individuals. An effective vaccine could substantially reduce the burden of cryptococcosis. However, a major gap in cryptococcal vaccine development has been the discovery of protective antigens to use in vaccines. Here, six cryptococcal proteins with potential as vaccine antigens were expressed recombinantly and purified. Mice were then vaccinated with glucan particle preparations containing each antigen. Of the six candidate vaccines, four protected mice from a lethal cryptococcal challenge. However, the degree of protection varied as a function of mouse strain and cryptococcal species. These preclinical studies identify cryptococcal proteins that could serve as candidate vaccine antigens and provide a proof of principle regarding the feasibility of protein antigen-based vaccines to protect against cryptococcosis. PMID- 29184019 TI - Gut Symbiont Bacteroides fragilis Secretes a Eukaryotic-Like Ubiquitin Protein That Mediates Intraspecies Antagonism. AB - Human gut Bacteroides species produce different types of toxins that antagonize closely related members of the gut microbiota. Some are toxic effectors delivered by type VI secretion systems, and others are non-contact-dependent secreted antimicrobial proteins. Many strains of Bacteroides fragilis secrete antimicrobial molecules, but only one of these toxins has been described to date (Bacteroidales secreted antimicrobial protein 1 [BSAP-1]). In this study, we describe a novel secreted protein produced by B. fragilis strain 638R that mediated intraspecies antagonism. Using transposon mutagenesis and deletion mutation, we identified a gene encoding a eukaryotic-like ubiquitin protein (BfUbb) necessary for toxin activity against a subset of B. fragilis strains. The addition of ubb into a heterologous background strain conferred toxic activity on that strain. We found this gene to be one of the most highly expressed in the B. fragilis genome. The mature protein is 84% similar to human ubiquitin but has an N-terminal signal peptidase I (SpI) signal sequence and is secreted extracellularly. We found that the mature 76-amino-acid synthetic protein has very potent activity, confirming that BfUbb mediates the activity. Analyses of human gut metagenomic data sets revealed that ubb is present in 12% of the metagenomes that have evidence of B. fragilis As 638R produces both BSAP-1 and BfUbb, we performed a comprehensive analysis of the toxin activity of BSAP-1 and BfUbb against a set of 40 B. fragilis strains, revealing that 75% of B. fragilis strains are targeted by one or the other of these two secreted proteins of strain 638R.IMPORTANCE We are just beginning to understand some of the important interactions that occur between microbes of the human gut microbiota that dictate the composition and abundance of its constituent members. The ability of one member to produce molecules that directly kill a coresident member has been shown among minor gut species and is just starting to be studied in the abundant Bacteroides species. Here, we show that some strains of Bacteroides fragilis have acquired a gene encoding a secreted eukaryotic-like ubiquitin protein with potent inhibitory activity against other B. fragilis stains. This is the first bacterially encoded ubiquitin-like molecule shown to function like a bacterial toxin. This molecule is an example of a gut symbiont acquiring and adapting a eukaryotic molecule likely to increase its competitiveness in the mammalian gut. Understanding antagonistic factors produced by abundant gut symbionts is an important prerequisite to properly engineer strains to colonize the gut for health benefits. PMID- 29184018 TI - Ancient Regulatory Role of Lysine Acetylation in Central Metabolism. AB - Lysine acetylation is a common protein post-translational modification in bacteria and eukaryotes. Unlike phosphorylation, whose functional role in signaling has been established, it is unclear what regulatory mechanism acetylation plays and whether it is conserved across evolution. By performing a proteomic analysis of 48 phylogenetically distant bacteria, we discovered conserved acetylation sites on catalytically essential lysine residues that are invariant throughout evolution. Lysine acetylation removes the residue's charge and changes the shape of the pocket required for substrate or cofactor binding. Two-thirds of glycolytic and tricarboxylic acid (TCA) cycle enzymes are acetylated at these critical sites. Our data suggest that acetylation may play a direct role in metabolic regulation by switching off enzyme activity. We propose that protein acetylation is an ancient and widespread mechanism of protein activity regulation.IMPORTANCE Post-translational modifications can regulate the activity and localization of proteins inside the cell. Similar to phosphorylation, lysine acetylation is present in both eukaryotes and prokaryotes and modifies hundreds to thousands of proteins in cells. However, how lysine acetylation regulates protein function and whether such a mechanism is evolutionarily conserved is still poorly understood. Here, we investigated evolutionary and functional aspects of lysine acetylation by searching for acetylated lysines in a comprehensive proteomic data set from 48 phylogenetically distant bacteria. We found that lysine acetylation occurs in evolutionarily conserved lysine residues in catalytic sites of enzymes involved in central carbon metabolism. Moreover, this modification inhibits enzymatic activity. Our observations suggest that lysine acetylation is an evolutionarily conserved mechanism of controlling central metabolic activity by directly blocking enzyme active sites. PMID- 29184020 TI - Bacteriophage Distributions and Temporal Variability in the Ocean's Interior. AB - Bacteriophages are numerically the most abundant DNA-containing entities in the oligotrophic ocean, yet how specific phage populations vary over time and space remains to be fully explored. Here, we conducted a metagenomic time-series survey of double-stranded DNA phages throughout the water column in the North Pacific Subtropical Gyre, encompassing 1.5 years from depths of 25 to 1,000 m. Viral gene sequences were identified in assembled metagenomic samples, yielding an estimated 172,385 different viral gene families. Viral marker gene distributions suggested that lysogeny was more prevalent at mesopelagic depths than in surface waters, consistent with prior prophage induction studies using mitomycin C. A total of 129 ALOHA viral genomes and genome fragments from 20 to 108 kbp were selected for further study, which represented the most abundant phages in the water column. Phage genotypes displayed discrete population structures. Most phages persisted throughout the time-series and displayed a strong depth structure that mirrored the stratified depth distributions of co-occurring bacterial taxa in the water column. Mesopelagic phages were distinct from surface water phages with respect to diversity, gene content, putative life histories, and temporal persistence, reflecting depth-dependent differences in host genomic architectures and phage reproductive strategies. The spatiotemporal distributions of the most abundant open-ocean bacteriophages that we report here provide new insight into viral temporal persistence, life history, and virus-host-environment interactions throughout the open-ocean water column.IMPORTANCE The North Pacific Subtropical Gyre represents one of the largest biomes on the planet, where microbial communities are central mediators of ecosystem dynamics and global biogeochemical cycles. Critical members of these communities are the viruses of marine bacteria, which can alter microbial metabolism and significantly influence their survival and productivity. To better understand these viral assemblages, we conducted genomic analyses of planktonic viruses over a seasonal cycle to ocean depths of 1,000 m. We identified 172,385 different viral gene families and 129 unique virus genotypes in this open-ocean setting. The spatiotemporal distributions of the most abundant open-ocean viruses that we report here provide new insights into viral temporal variability, life history, and virus-host-environment interactions throughout the water column. PMID- 29184021 TI - Forward Genetics Approach Reveals Host Genotype-Dependent Importance of Accessory Chromosomes in the Fungal Wheat Pathogen Zymoseptoria tritici. AB - The fungal wheat pathogen Zymoseptoria tritici possesses a large complement of accessory chromosomes showing presence/absence polymorphism among isolates. These chromosomes encode hundreds of genes; however, their functional role and why the chromosomes have been maintained over long evolutionary times are so far not known. In this study, we addressed the functional relevance of eight accessory chromosomes in reference isolate IPO323. We induced chromosome losses by inhibiting the beta-tubulin assembly during mitosis using carbendazim and generated several independent isogenic strains, each lacking one of the accessory chromosomes. We confirmed chromosome losses by electrophoretic karyotyping and whole-genome sequencing. To assess the importance of the individual chromosomes during host infection, we performed in planta assays comparing disease development results in wild-type and chromosome mutant strains. Loss of the accessory chromosomes 14, 16, 18, 19, and 21 resulted in increased virulence on wheat cultivar Runal but not on cultivars Obelisk, Titlis, and Riband. Moreover, some accessory chromosomes affected the switch from biotrophy to necrotrophy as strains lacking accessory chromosomes 14, 18, 19, and 21 showed a significantly earlier onset of necrosis than the wild type on the Runal cultivar. In general, we observed that the timing of the lifestyle switch affects the fitness of Z. tritici Taking the results together, this study was the first to use a forward genetics approach to demonstrate a cultivar-dependent functional relevance of the accessory chromosomes of Z. tritici during host infection.IMPORTANCEZymoseptoria tritici is a prominent fungal pathogen of wheat of worldwide distribution. This fungus shows a remarkable genome organization, with a large number of chromosomes that are present in only some isolates and therefore considered to be "accessory" chromosomes. To date, the function of these accessory chromosomes in Z. tritici has been unknown, although their maintenance in the species over evolutionary times suggests a functional relevance. Here we deleted whole accessory chromosomes to test the effect of these chromosomes on host specificity and virulence of the fungus. We show for the first time that some accessory chromosomes of Z. tritici affect the fitness of the fungus during host infection in a cultivar-dependent manner. These results show that the accessory chromosomes encode host-specific virulence determinants having a negative effect on fitness. Understanding the population dynamic of the accessory chromosomes and the molecular interaction of pathogen and plant traits is crucial to improve wheat breeding strategies. PMID- 29184022 TI - Interventions on Metabolism: Making Antibiotic-Susceptible Bacteria. AB - Antibiotics act on bacterial metabolism, and antibiotic resistance involves changes in this metabolism. Interventions on metabolism with drugs might therefore modify drug susceptibility and drug resistance. In their recent article, Martin Vestergaard et al. (mBio 8:e01114-17, 2017, https://doi.org/10.1128/mBio.01114-17) illustrate the possibility of converting intrinsically resistant bacteria into susceptible ones. They reported that inhibition of a central metabolic enzyme, ATP synthase, allows otherwise ineffective polymyxin antibiotics to act on Staphylococcus aureus The study of the intrinsic resistome of bacterial pathogens has shown that several metabolic genes, including multigene transcriptional regulators, contribute to antibiotic resistance. In some cases, these genes only marginally increase antibiotic resistance, but reduced levels of susceptibility might be critical in the evolution or resistance under low antibiotic concentrations or in the clinical response of highly resistant bacteria. Drug interventions on bacterial metabolism might constitute a critical adjuvant therapy in combination with antibiotics to ensure susceptibility of pathogens with intrinsic or acquired antimicrobial resistance. PMID- 29184023 TI - Effects of Mutations on Replicative Fitness and Major Histocompatibility Complex Class I Binding Affinity Are Among the Determinants Underlying Cytotoxic-T Lymphocyte Escape of HIV-1 Gag Epitopes. AB - Certain "protective" major histocompatibility complex class I (MHC-I) alleles, such as B*57 and B*27, are associated with long-term control of HIV-1 in vivo mediated by the CD8+ cytotoxic-T-lymphocyte (CTL) response. However, the mechanism of such superior protection is not fully understood. Here we combined high-throughput fitness profiling of mutations in HIV-1 Gag, in silico prediction of MHC-peptide binding affinity, and analysis of intraperson virus evolution to systematically compare differences with respect to CTL escape mutations between epitopes targeted by protective MHC-I alleles and those targeted by nonprotective MHC-I alleles. We observed that the effects of mutations on both viral replication and MHC-I binding affinity are among the determinants of CTL escape. Mutations in Gag epitopes presented by protective MHC-I alleles are associated with significantly higher fitness cost and lower reductions in binding affinity with respect to MHC-I. A linear regression model accounting for the effect of mutations on both viral replicative capacity and MHC-I binding can explain the protective efficacy of MHC-I alleles. Finally, we found a consistent pattern in the evolution of Gag epitopes in long-term nonprogressors versus progressors. Overall, our results suggest that certain protective MHC-I alleles allow superior control of HIV-1 by targeting epitopes where mutations typically incur high fitness costs and small reductions in MHC-I binding affinity.IMPORTANCE Understanding the mechanism of viral control achieved in long-term nonprogressors with protective HLA alleles provides insights for developing functional cure of HIV infection. Through the characterization of CTL escape mutations in infected persons, previous researchers hypothesized that protective alleles target epitopes where escape mutations significantly reduce viral replicative capacity. However, these studies were usually limited to a few mutations observed in vivo Here we utilized our recently developed high-throughput fitness profiling method to quantitatively measure the fitness of mutations across the entirety of HIV-1 Gag. The data enabled us to integrate the results with in silico prediction of MHC-peptide binding affinity and analysis of intraperson virus evolution to systematically determine the differences in CTL escape mutations between epitopes targeted by protective HLA alleles and those targeted by nonprotective HLA alleles. We observed that the effects of Gag epitope mutations on HIV replicative fitness and MHC-I binding affinity are among the major determinants of CTL escape. PMID- 29184024 TI - Identification of Fitness Determinants during Energy-Limited Growth Arrest in Pseudomonas aeruginosa. AB - Microbial growth arrest can be triggered by diverse factors, one of which is energy limitation due to scarcity of electron donors or acceptors. Genes that govern fitness during energy-limited growth arrest and the extent to which they overlap between different types of energy limitation are poorly defined. In this study, we exploited the fact that Pseudomonas aeruginosa can remain viable over several weeks when limited for organic carbon (pyruvate) as an electron donor or oxygen as an electron acceptor. ATP values were reduced under both types of limitation, yet more severely in the absence of oxygen. Using transposon insertion sequencing (Tn-seq), we identified fitness determinants in these two energy-limited states. Multiple genes encoding general functions like transcriptional regulation and energy generation were required for fitness during carbon or oxygen limitation, yet many specific genes, and thus specific activities, differed in their relevance between these states. For instance, the global regulator RpoS was required during both types of energy limitation, while other global regulators such as DksA and LasR were required only during carbon or oxygen limitation, respectively. Similarly, certain ribosomal and tRNA modifications were specifically required during oxygen limitation. We validated fitness defects during energy limitation using independently generated mutants of genes detected in our screen. Mutants in distinct functional categories exhibited different fitness dynamics: regulatory genes generally manifested a phenotype early, whereas genes involved in cell wall metabolism were required later. Together, these results provide a new window into how P. aeruginosa survives growth arrest.IMPORTANCE Growth-arrested bacteria are ubiquitous in nature and disease yet understudied at the molecular level. For example, growth-arrested cells constitute a major subpopulation of mature biofilms, serving as an antibiotic-tolerant reservoir in chronic infections. Identification of the genes required for survival of growth arrest (encompassing entry, maintenance, and exit) is an important first step toward understanding the physiology of bacteria in this state. Using Tn-seq, we identified and validated genes required for fitness of Pseudomonas aeruginosa when energy limited for organic carbon or oxygen, which represent two common causes of growth arrest for P. aeruginosa in diverse habitats. This unbiased, genome-wide survey is the first to reveal essential activities for a pathogen experiencing different types of energy limitation, finding both shared and divergent activities that are relevant at different survival stages. Future efforts can now be directed toward understanding how the biomolecules responsible for these activities contribute to fitness under these conditions.

AB - Long-term exposure to trace levels of arsenic (As) in shallow groundwater used for drinking and irrigation puts millions of people at risk of chronic disease. Although microbial processes are implicated in mobilizing arsenic from aquifer sediments into groundwater, the precise mechanism remains ambiguous. The goal of this work was to target, for the first time, a comprehensive suite of state-of the-art molecular techniques in order to better constrain the relationship between indigenous microbial communities and the iron and arsenic mineral phases present in sediments at two well-characterized arsenic-impacted aquifers in Bangladesh. At both sites, arsenate [As(V)] was the major species of As present in sediments at depths with low aqueous As concentrations, while most sediment As was arsenite [As(III)] at depths with elevated aqueous As concentrations. This is consistent with a role for the microbial As(V) reduction in mobilizing arsenic. 16S rRNA gene analysis indicates that the arsenic-rich sediments were colonized by diverse bacterial communities implicated in both dissimilatory Fe(III) and As(V) reduction, while the correlation analyses involved phylogenetic groups not normally associated with As mobilization. Findings suggest that direct As redox transformations are central to arsenic fate and transport and that there is a residual reactive pool of both As(V) and Fe(III) in deeper sediments that could be released by microbial respiration in response to hydrologic perturbation, such as increased groundwater pumping that introduces reactive organic carbon to depth.IMPORTANCE The consumption of arsenic in waters collected from tube wells threatens the lives of millions worldwide and is particularly acute in the floodplains and deltas of southern Asia. The cause of arsenic mobilization from natural sediments within these aquifers to groundwater is complex, with recent studies suggesting that sediment-dwelling microorganisms may be the cause. In the absence of oxygen at depth, specialist bacteria are thought able to use metals within the sediments to support their metabolism. Via these processes, arsenic contaminated iron minerals are transformed, resulting in the release of arsenic into the aquifer waters. Focusing on a field site in Bangladesh, a comprehensive, multidisciplinary study using state-of-the-art geological and microbiological techniques has helped better understand the microbes that are present naturally in a high-arsenic aquifer and how they may transform the chemistry of the sediment to potentially lethal effect.

AB - Phosphatidylinositol 3-P (PI3P) is a signaling molecule that controls a variety of processes in endosomal, autophagic, and vacuolar/lysosomal trafficking in yeasts and mammals. Vacuolar protein sorting 34 (Vps34) is a conserved PI3K present in multiple complexes with specific functions and regulation. In yeast, the PI3K complex II consists of Vps34p, Vps15p, Vps30p/Atg6p, and Vps38p, and is essential for vacuolar protein sorting. Here, we describe the Arabidopsis (Arabidopsis thaliana) homolog of yeast Vps38p and human UV radiation resistance associated gene protein. Arabidopsis VPS38 interacts with VPS30/ATG6 both in yeast and in planta. Although the level of PI3P in Arabidopsis vps38 mutants is similar to that in wild type, vps38 cells contain enlarged multivesicular endosomes and fewer organelles enriched in PI3P than the wild type. The vps38 mutants are defective in the trafficking of vacuolar cargo and its receptor VACUOLAR SORTING RECEPTOR2;1. The mutants also exhibit abnormal cytoplasmic distributions of endocytic cargo, such as auxin efflux carriers PINFORMED1 (PIN1) and PIN2. Constitutive autophagy is normal in the mutants but starvation-induced autophagy was slightly inhibited. We conclude that Arabidopsis VPS38 is dispensable for autophagy but essential for efficient targeting of biosynthetic and endocytic cargo to the vacuole. PMID- 29184028 TI - Identification of a New Host Factor Required for Antiviral RNAi and Amplification of Viral siRNAs. AB - Small interfering RNAs (siRNAs) are processed from virus-specific dsRNA to direct antiviral RNA interference (RNAi) in diverse eukaryotic hosts. We have recently performed a sensitized genetic screen in Arabidopsis (Arabidopsis thaliana) and identified two related phospholipid flippases required for antiviral RNAi and the amplification of virus-derived siRNAs by plant RNA-dependent RNA polymerase1 (RDR1) and RDR6. Here we report the identification and cloning of ANTIVIRAL RNAI DEFECTIVE2 (AVI2) from the same genetic screen. AVI2 encodes a multispan transmembrane protein broadly conserved in plants and animals with two homologous human proteins known as magnesium transporters. We show that avi2 mutant plants display no developmental defects and develop severe disease symptoms after infection with a mutant Cucumber mosaic virus (CMV) defective in RNAi suppression. AVI2 is induced by CMV infection, particularly in veins, and is required for antiviral RNAi and RDR6-dependent biogenesis of viral siRNAs. AVI2 is also necessary for Dicer-like2-mediated amplification of 22-nucleotide viral siRNAs induced in dcl4 mutant plants by infection, but dispensable for RDR6 dependent biogenesis of endogenous transacting siRNAs. Further genetic studies illustrate that AVI2 plays a partially redundant role with AVI2H, the most closely related member in the AVI2 gene family, in RDR1-dependent biogenesis of viral siRNAs and the endogenous virus-activated siRNAs (vasi-RNAs). Interestingly, we discovered a specific genetic interaction of AVI2 with AVI1 flippase that is critical for plant development. We propose that AVI1 and AVI2 participate in the virus-induced formation of the RDR1/RDR6-specific, membrane bound RNA synthesis compartment, essential for the biogenesis of highly abundant viral siRNAs and vasi-RNAs. PMID- 29184030 TI - Arabidopsis ATXR2 deposits H3K36me3 at the promoters of LBD genes to facilitate cellular dedifferentiation. AB - Cellular dedifferentiation, the transition of differentiated somatic cells to pluripotent stem cells, ensures developmental plasticity and contributes to wound healing in plants. Wounding induces cells to form a mass of unorganized pluripotent cells called callus at the wound site. Explanted cells can also form callus tissues in vitro. Reversible cellular differentiation-dedifferentiation processes in higher eukaryotes are controlled mainly by chromatin modifications. We demonstrate that ARABIDOPSIS TRITHORAX-RELATED 2 (ATXR2), a histone lysine methyltransferase that promotes the accumulation of histone H3 proteins that are trimethylated on lysine 36 (H3K36me3) during callus formation, promotes early stages of cellular dedifferentiation through activation of LATERAL ORGAN BOUNDARIES DOMAIN (LBD) genes. The LBD genes of Arabidopsis thaliana are activated during cellular dedifferentiation to enhance the formation of callus. Leaf explants from Arabidopsis atxr2 mutants exhibited a reduced ability to form callus and a substantial reduction in LBD gene expression. ATXR2 bound to the promoters of LBD genes and was required for the deposition of H3K36me3 at these promoters. ATXR2 was recruited to LBD promoters by the transcription factors AUXIN RESPONSE FACTOR 7 (ARF7) and ARF19. Leaf explants from arf7-1arf19-2 double mutants were defective in callus formation and showed reduced H3K36me3 accumulation at LBD promoters. Genetic analysis provided further support that ARF7 and ARF19 were required for the ability of ATXR2 to promote the expression of LBD genes. These observations indicate that the ATXR2-ARF-LBD axis is key for the epigenetic regulation of callus formation in Arabidopsis. PMID- 29184032 TI - Opening the Orai1 gates. AB - How the store-operated channel Orai1 opens and the number of gates that control channel opening and conductance remain unclear. In this issue of Science Signaling, Frischauf et al report on the importance of the basic pore region in addition to the hydrophobic gate in channel gating and identify a site in transmembrane domain 2 (TM2) that controls pore opening. PMID- 29184029 TI - Update: Plant Cortical Microtubule Arrays. PMID- 29184031 TI - Transmembrane helix connectivity in Orai1 controls two gates for calcium dependent transcription. AB - The channel Orai1 requires Ca2+ store depletion in the endoplasmic reticulum and an interaction with the Ca2+ sensor STIM1 to mediate Ca2+ signaling. Alterations in Orai1-mediated Ca2+ influx have been linked to several pathological conditions including immunodeficiency, tubular myopathy, and cancer. We screened large-scale cancer genomics data sets for dysfunctional Orai1 mutants. Five of the identified Orai1 mutations resulted in constitutively active gating and transcriptional activation. Our analysis showed that certain Orai1 mutations were clustered in the transmembrane 2 helix surrounding the pore, which is a trigger site for Orai1 channel gating. Analysis of the constitutively open Orai1 mutant channels revealed two fundamental gates that enabled Ca2+ influx: Arginine side chains were displaced so they no longer blocked the pore, and a chain of water molecules formed in the hydrophobic pore region. Together, these results enabled us to identify a cluster of Orai1 mutations that trigger Ca2+ permeation associated with gene transcription and provide a gating mechanism for Orai1. PMID- 29184034 TI - MEK inhibitor trametinib does not prevent the growth of anaplastic lymphoma kinase (ALK)-addicted neuroblastomas. AB - Activation of the RAS-RAF-MEK-ERK signaling pathway is implicated in driving the initiation and progression of multiple cancers. Several inhibitors targeting the RAS-MAPK pathway are clinically approved as single- or polyagent therapies for patients with specific types of cancer. One example is the MEK inhibitor trametinib, which is included as a rational polytherapy strategy for treating EML4-ALK-positive, EGFR-activated, or KRAS-mutant lung cancers and neuroblastomas that also contain activating mutations in the RAS-MAPK pathway. In addition, in neuroblastoma, a heterogeneous disease, relapse cases display an increased rate of mutations in ALK, NRAS, and NF1, leading to increased activation of RAS-MAPK signaling. Co-targeting ALK and the RAS-MAPK pathway is an attractive option, because monotherapies have not yet produced effective results in ALK-addicted neuroblastoma patients. We evaluated the response of neuroblastoma cell lines to MEK-ERK pathway inhibition by trametinib. In contrast to RAS-MAPK pathway-mutated neuroblastoma cell lines, ALK-addicted neuroblastoma cells treated with trametinib showed increased activation (inferred by phosphorylation) of the kinases AKT and ERK5. This feedback response was mediated by the mammalian target of rapamycin complex 2-associated protein SIN1, resulting in increased survival and proliferation that depended on AKT signaling. In xenografts in mice, trametinib inhibited the growth of EML4-ALK-positive non-small cell lung cancer and RAS-mutant neuroblastoma but not ALK-addicted neuroblastoma. Thus, our results advise against the seemingly rational option of using MEK inhibitors to treat ALK-addicted neuroblastoma.

PMID- 29184033 TI - Networks of enzymatically oxidized membrane lipids support calcium-dependent coagulation factor binding to maintain hemostasis. AB - Blood coagulation functions as part of the innate immune system by preventing bacterial invasion, and it is critical to stopping blood loss (hemostasis). Coagulation involves the external membrane surface of activated platelets and leukocytes. Using lipidomic, genetic, biochemical, and mathematical modeling approaches, we found that enzymatically oxidized phospholipids (eoxPLs) generated by the activity of leukocyte or platelet lipoxygenases (LOXs) were required for normal hemostasis and promoted coagulation factor activities in a Ca2+- and phosphatidylserine (PS)-dependent manner. In wild-type mice, hydroxyeicosatetraenoic acid-phospholipids (HETE-PLs) enhanced coagulation and restored normal hemostasis in clotting-deficient animals genetically lacking p12 LOX or 12/15-LOX activity. Murine platelets generated 22 eoxPL species, all of which were missing in the absence of p12-LOX. Humans with the thrombotic disorder antiphospholipid syndrome (APS) had statistically significantly increased HETE PLs in platelets and leukocytes, as well as greater HETE-PL immunoreactivity, than healthy controls. HETE-PLs enhanced membrane binding of the serum protein beta2GP1 (beta2-glycoprotein 1), an event considered central to the autoimmune reactivity responsible for APS symptoms. Correlation network analysis of 47 platelet eoxPL species in platelets from APS and control subjects identified their enzymatic origin and revealed a complex network of regulation, with the abundance of 31 p12-LOX-derived eoxPL molecules substantially increased in APS. In summary, circulating blood cells generate networks of eoxPL molecules, including HETE-PLs, which change membrane properties to enhance blood coagulation and contribute to the excessive clotting and immunoreactivity of patients with APS. PMID- 29184035 TI - Practice Variation in Acute Bronchiolitis: A Pediatric Emergency Research Networks Study. AB - BACKGROUND AND OBJECTIVES: Studies characterizing hospitalizations in bronchiolitis did not identify patients receiving evidence-based supportive therapies (EBSTs). We aimed to evaluate intersite and internetwork variation in receipt of >=1 EBSTs during the hospital management of infants diagnosed with bronchiolitis in 38 emergency departments of pediatric emergency research networks in Canada, the United States, Australia, New Zealand, the United Kingdom, Ireland, Spain, and Portugal. We hypothesized that there would be significant variation, adjusted for patient characteristics. METHODS: Retrospective cohort study of previously healthy infants aged <12 months with bronchiolitis. Our primary outcome was that hospitalization occurred with EBST (ie, parenteral fluids, oxygen, or airway support). RESULTS: Out of 3725 participants, 1466 (39%) were hospitalized, and 1023 out of 1466 participants (69.8%) received EBST. The use of EBST varied by site (P < .001; range 6%-99%, median 23%), but not by network (P = .2). Significant multivariable predictors and their odds ratios (ORs) were as follows: age (0.9), oxygen saturation (1.3), apnea (3.4), dehydration (3.2), nasal flaring and/or grunting (2.4), poor feeding (2.1), chest retractions (1.9), and respiratory rate (1.2). The use of pharmacotherapy and radiography varied by network and site (P < .001), with respective intersite ranges 2% to 79% and 1.6% to 81%. Compared with Australia and New Zealand, the multivariable OR for the use of pharmacotherapy in Spain and Portugal was 22.7 (95% confidence interval [CI]: 4.5-111), use in Canada was 11.5 (95% CI: 3.7-36), use in the United States was 6.8 (95% CI: 2.3-19.8), and use in the United Kingdom was 1.4 (95% CI: 0.4-4.2). Compared with United Kingdom, OR for radiography use in the United States was 4.9 (95% CI 2.0-12.2), use in Canada was 4.9 (95% CI 1.9-12.6), use in Spain and Portugal was 2.4 (95% CI 0.6-9.8), and use in Australia and New Zealand was 1.8 (95% CI 0.7-4.7). CONCLUSIONS: More than 30% of infants hospitalized with bronchiolitis received no EBST. The hospital site was a source of variation in all study outcomes, and the network also predicted the use of pharmacotherapy and radiography.

PMID- 29184044 TI - Intra-arterial oxidative stress correlates negatively with cognitive function and positively with postoperative ischemic lesions in carotid artery stenosis stenting. AB - BACKGROUND AND PURPOSE: Carotid plaque contains biologically active substances released into the blood during carotid artery stenting (CAS). The main purpose of this prospective study was to analyse sequential changes in oxidative stress during CAS and their relationship to clinical factors. METHODS: Twenty-two consecutive CAS procedures were performed between May 2014 and April 2016. Arterial blood was collected four times: (1) after the sheath insertion without edaravone; (2) pre-angioplasty with edaravone from the carotid artery; (3) after post-stenting angioplasty from an occluded carotid artery; and (4) before sheath removal. Derivatives of reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) were measured photometrically. The relationship between d-ROMs or BAP and preoperatively investigated biochemical parameters, cognitive function, and number of diffusion-weighted image (DWI) high spot lesions was analysed using one-way ANOVA and the Tukey-Kramer HSD test. RESULTS: The d-ROM values for CAS were 355+/-58.8 Carratelli Units at sheath insertion, 315+/-57.2 after edaravone infusion, 328+/-56.8 after post-stenting angioplasty, and 315+/-53.0 just before sheath removal. The d-ROM values were reduced significantly after edaravone infusion (P<0.05). The BAP at sheath insertion was reduced significantly according to age (P<0.05). The d-ROMs at sheath insertion correlated negatively with the dementia scale and positively with the post-CAS DWI high spots (1.00+/-1.07; P<0.05). Other biochemical parameters did not correlate with the d-ROM values or BAP. CONCLUSION: Oxidative stress is correlated negatively with cognitive function and positively with postoperative ischemic lesions. Antioxidant potential decreases with ageing. PMID- 29184045 TI - Cerebral arteriovenous malformation draining vein stenosis is associated with atherosclerotic risk factors. AB - OBJECTIVE: The pathogenesis of venous outflow stenosis associated with cerebral arteriovenous malformation (AVM) draining veins is poorly understood. We sought to determine the relationship between venous stenosis and atherosclerotic risk factors. MATERIALS AND METHODS: All patients with an AVM seen at our institution between 1990 and 2016 were retrospectively reviewed. Patients <18 years of age were excluded. Patients were classified into two groups based on the presence or absence of venous stenosis. Patient charts were reviewed for the following atherosclerotic risk factors: age >50 years, sex, race, hypertension, type 2 diabetes mellitus, hyperlipidemia, coronary artery disease, chronic kidney disease stage III, and cigarette smoking. The relationship between venous stenosis and atherosclerotic risk factors was assessed using univariate and multivariate analyses. RESULTS: 278 patients were included (mean age 41 years, 55% men). Venous stenosis was present in 87 patients (31% of the cohort). The presence of venous stenosis was significantly associated with age >50 years (P=0.05), hypertension (P=0.05), diabetes (P=0.02), and hyperlipidemia (P=0.001). Multivariate analysis showed that hyperlipidemia (P=0.05) was predictive of draining vein stenosis. CONCLUSIONS: Venous stenosis is associated with several atherosclerotic risk factors, suggesting that cerebral AVM venous outflow stenosis occurs by a degenerative process. Additional studies can show whether these modifiable risk factors may be targeted to prevent draining vein stenosis and AVM rupture. PMID- 29184046 TI - Decoding resistant hypertension signalling pathways. AB - Resistant hypertension (RH) is a clinical condition in which the hypertensive patient has become resistant to drug therapy and is often associated with increased cardiovascular morbidity and mortality. Several signalling pathways have been studied and related to the development and progression of RH: modulation of sympathetic activity by leptin and aldosterone, primary aldosteronism, arterial stiffness, endothelial dysfunction and variations in the renin-angiotensin-aldosterone system (RAAS). miRNAs comprise a family of small non-coding RNAs that participate in the regulation of gene expression at post transcriptional level. miRNAs are involved in the development of both cardiovascular damage and hypertension. Little is known of the molecular mechanisms that lead to development and progression of this condition. This review aims to cover the potential roles of miRNAs in the mechanisms associated with the development and consequences of RH, and explore the current state of the art of diagnostic and therapeutic tools based on miRNA approaches. PMID- 29184047 TI - The Impact of Using Non-Birth Sex on the Interpretation of Spirometry Data in Subjects With Air-Flow Obstruction. AB - BACKGROUND: Sex is an important determinant of lung capacity and function. This study examined the impact of using non-birth sex on the interpretation of spirometry data in transgender subjects with air-flow obstruction. METHODS: This study was a retrospective analysis of anonymous spirometry data. Eighty adult male and 80 adult female subjects were chosen from the database via random sampling. FVC, FEV1, and FEV1/FVC were collected and analyzed. Differences in percent of predicted, Z scores, classification of disease severity, and the incidence of a value migrating above or below the lower limit of normal between sex assignments were examined. RESULTS: For born male subjects, percent of predicted for FVC and FEV1 were significantly higher when the female sex was used: 100.5% versus 118.5% and 78% versus 91.5%, respectively (P < .001). FEV1/FVC Z score was -2.53 for male sex and -2.65 for female sex (P = .004). The presence of obstruction was not affected by sex assignment. Use of non-birth sex moved some FVC and FEV1 data above the lower limit of normal and improved severity classification in others. For born female subjects, percent of predicted for FVC and FEV1 were significantly lower when the male sex was used: 102% versus 87.5% and 81.5% versus 70.5%, respectively (P < .001). FEV1/FVC Z score was -2.17 for female sex and -2.12 for male sex (P < .001). Six born female subjects had their FEV1/FVC normalized when male sex was used. Use of non-birth sex moved some FVC and FEV1 data below the lower limit of normal and worsened severity classification in others. In total, using the non-birth sex affected spirometry interpretation in 45% of born male subjects and 70% of born female subjects. CONCLUSIONS: In transgender subjects with air-flow obstruction, using non-birth sex to calculate predicted spirometry values may have a significant impact on test interpretation and place these patients at risk for misdiagnosis and inappropriate treatment. PMID- 29184048 TI - Utilizing Respiratory Therapists to Reduce Costs of Care. AB - INTRODUCTION: Changes to the reimbursement of respiratory care services over the past 26 years make it imperative that respiratory therapists (RTs) demonstrate cost savings to establish their value. Therefore, this systematic review evaluated the cost-related impacts from utilizing RTs to deliver care when compared to other care providers. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to guide the search process. The study addressed articles across all age groups and care settings that compared the cost of care provided by RTs to a comparison group. Studies were excluded if they were not written in English, described care provided outside of the United States, did not provide quantitative data, or lacked a comparison group. RESULTS: A total of 4,120 articles emerged from the search process, of which 60 qualified for a full text review. Cost savings were evaluated for the 28 articles included in this review, noting the study design, the specific respiratory care practice, use of protocols, clinical setting, and age group. The most frequently studied topic was mechanical ventilation, which along with disease management represented by the most randomized, controlled trials for the study design. The clinical practice area notably absent was home care. CONCLUSIONS: Although cost comparisons across studies could not be made due to the inconsistent manner in which data were reported, evidence demonstrated that care provided by RTs yielded both direct and indirect cost reductions, which were achieved through protocol utilization, specialized expertise, and autonomous decision making. The care provided was consistent with care provided by other disciplines. It is critical for the respiratory care profession to highlight key clinical practice areas for future research, to establish uniform reporting measures for outcomes, and to foster the development of future respiratory care researchers to affirm the value that respiratory therapists add to patient care. PMID- 29184049 TI - Does Diaphragmatic Electrical Activity in Preterm Infants Predict Extubation Success? AB - BACKGROUND: Despite many advances in respiratory care and mechanical ventilation, neonatologists lack an objective tool to aid in decision making for timely extubation. Electrical activity of the diaphragm (EAdi), a measure of neural respiratory drive and inspiratory load, may be a useful predictor of extubation success in preterm neonates. The objective of this work was to investigate whether peak EAdi could distinguish successful versus failed extubation in mechanically ventilated preterm infants. METHODS: We examined peak EAdi as a predictor of extubation outcome in a convenience sample of 21 preterm infants with respiratory distress syndrome requiring mechanical ventilation. Infants were ventilated with a VN500 ventilator using volume guarantee mode and extubated per unit protocol. Peak EAdi was continuously measured with an EAdi catheter in the esophagus to obtain data at 1-min intervals for 24 h before extubation. The primary outcome was extubation success, defined as not requiring re-intubation for at least 72 h. RESULTS: Twenty one premature infants with respiratory distress syndrome included in the study had a mean +/- SD) gestational age of 28 +/- 2.6 weeks and mean birthweight of 1,208 +/- 611 g. The first extubation attempt occurred at a median age of 1 d (interquartile range 1-2 d). One third of the infants failed the first extubation attempt. Infants with failed extubations were significantly smaller (mean +/- SD birthweight 788 +/- 266 g versus 1,417 +/ 632 g) and of lower gestational age (mean +/- SD 26 +/- 1.9 weeks versus 29 +/- 2.6 weeks) compared with those with successful extubation. Mean peak EAdi before extubation did not differ between the 2 groups. CONCLUSIONS: This small study suggests that the pre-extubation peak EAdi does not predict extubation success.

AB - BACKGROUND A Bochdalek hernia (BH) is a rare congenital condition consisting of a posterolateral defect in the diaphragm. A para-esophageal hernia (PEH) is a rare variant of hiatus hernia. BH and PEH may present with gastric volvulus or incarceration, requiring emergency treatment. Minimally invasive surgery is the preferred treatment, particularly for elderly patients and patients with comorbidities. The occurrence of BH with concomitant PEH is a very rare event. We describe a case of an octogenarian patient with BH and concomitant PEH treated laparoscopically. CASE REPORT An 81-year-old male patient, without significant comorbidities, presented with a two-month history of severe chest pain and vomiting after eating. Cardiological investigations ruled out cardiac ischemia, infarction, or other cardiovascular abnormalities. Chest and abdominal computed tomography (CT) imaging demonstrated a large diaphragmatic hernia, with the entire stomach in the left thorax. Laboratory results showed mild anemia and a low iron level. The patient underwent simultaneous laparoscopic repair of a BH and a PEH with mesh reinforcement without antireflux fundoplication. The patient's postoperative recovery was uneventful. CONCLUSIONS We have presented a rare case of BH with concomitant PEH in an octogenarian that was successfully treated with laparoscopic surgery. Although these two forms of hernia are a very rare association, this case report illustrates that the surgical approach should be individualized in each patient's case to ensure a successful surgical outcome. In this case, the decision was made to suture the diaphragmatic crura and reinforce the diaphragm repair with mesh, rather than by fundoplication. PMID- 29184051 TI - Clinical Efficacy of Anterior Partial Corpectomy and Titanium Mesh Fusion and Internal Fixation for Treatment of Old Fracture Dislocation of the Lower Cervical Spine. AB - BACKGROUND The aim of this study was to analyze the clinical features and to evaluate the efficacy of anterior partial corpectomy and titanium mesh fusion and internal fixation of old fracture dislocation of the lower cervical spine. MATERIAL AND METHODS We retrospectively analyzed the clinical data of 52 patients with old lower cervical fracture and dislocation treated with anterior partial corpectomy and titanium mesh fusion fixation between January 2008 and December 2013, with a mean follow-up period of 4.1 years. There were 35 males and 17 females. Patient radiological data and clinical parameters were recorded and compared before and after the operations. RESULTS The average follow-up was 4.1 years. Intervertebral height and physiological curvature were well-reconstructed for all cases. No loosening or rupturing of titanium plate or screw occurred. The neurological function of the patients with incomplete spinal cord injury was significantly improved, and the function of the nerve roots at the injury level was also improved in patients with complete spinal cord injury. Bone fusion was completed within 6 months to 1 year after surgery. CONCLUSIONS Completed decompression, sequence and physiological curvature of the cervical vertebra, immediate and long-term anterior cervical column support, and nerve function restoration can be achieved by using anterior partial corpectomy and titanium mesh fusion and internal fixation to treat old fracture dislocation of the lower cervical spine. For cases with locked facet joints or posterior structures invading the vertebral canal, the combined anterior and posterior approaches should be performed, when necessary, to achieve better results. PMID- 29184053 TI - A Co3O4-CDots-C3N4 three component electrocatalyst design concept for efficient and tunable CO2 reduction to syngas. AB - Syngas, a CO and H2 mixture mostly generated from non-renewable fossil fuels, is an essential feedstock for production of liquid fuels. Electrochemical reduction of CO2 and H+/H2O is an alternative renewable route to produce syngas. Here we introduce the concept of coupling a hydrogen evolution reaction (HER) catalyst with a CDots/C3N4 composite (a CO2 reduction catalyst) to achieve a cheap, stable, selective and efficient route for tunable syngas production. Co3O4, MoS2, Au and Pt serve as the HER component. The Co3O4-CDots-C3N4 electrocatalyst is found to be the most efficient among the combinations studied. The H2/CO ratio of the produced syngas is tunable from 0.07:1 to 4:1 by controlling the potential. This catalyst is highly stable for syngas generation (over 100 h) with no other products besides CO and H2. Insight into the mechanisms balancing between CO2 reduction and H2 evolution when applying the HER-CDots-C3N4 catalyst concept is provided. PMID- 29184052 TI - Notch transactivates Rheb to maintain the multipotency of TSC-null cells. AB - Differentiation abnormalities are a hallmark of tuberous sclerosis complex (TSC) manifestations; however, the genesis of these abnormalities remains unclear. Here we report on mechanisms controlling the multi-lineage, early neuronal progenitor and neural stem-like cell characteristics of lymphangioleiomyomatosis (LAM) and angiomyolipoma cells. These mechanisms include the activation of a previously unreported Rheb-Notch-Rheb regulatory loop, in which the cyclic binding of Notch1 to the Notch-responsive elements (NREs) on the Rheb promoter is a key event. This binding induces the transactivation of Rheb. The identified NRE2 and NRE3 on the Rheb promoter are important to Notch-dependent promoter activity. Notch cooperates with Rheb to block cell differentiation via similar mechanisms in mouse models of TSC. Cell-specific loss of Tsc1 within nestin-expressing cells in adult mice leads to the formation of kidney cysts, renal intraepithelial neoplasia, and invasive papillary renal carcinoma. PMID- 29184054 TI - Meta-analysis of the interaction between serotonin transporter promoter variant, stress, and posttraumatic stress disorder. AB - Exposure to stress predicts the occurrence of posttraumatic stress disorder (PTSD) in individuals harboring the serotonin transporter promoter variant 5 HTTLPR. We carried out a meta-analysis of studies investigating the interaction between 5-HTTLPR, stress, and PTSD to clarify the interrelatedness of these factors. We reviewed all relevant studies published in English before May 2016. The Liptak-Stouffer z-score method for meta-analysis was applied to combined data. The z score was separately calculated for the stressful life events, childhood adversity, bi- and triallelic loci, and cross-sectional and longitudinal studies subgroups. A total of 14 studies with 15,883 subjects met our inclusion criteria. We found strong evidence that the presence of 5-HTTLPR influenced the relationship between stress and PTSD (P = 0.00003), with the strongest effects observed in the cross-sectional and longitudinal groups (P = 0.01 and 2.0 * 10-6, respectively). Stressful life events and childhood adversity separately interacted with 5-HTTLPR in PTSD (P = 2.0 * 10-8 and 0.003, respectively). When the studies were stratified by locus classification, the evidence was stronger for the triallelic (P = 4.0 * 10-8) than for the biallelic (P = 0.054) locus subgroup. There was strong evidence that 5-HTTLPR influences the relationship between stress and PTSD. PMID- 29184055 TI - Giant barocaloric effects over a wide temperature range in superionic conductor AgI. AB - Current interest in barocaloric effects has been stimulated by the discovery that these pressure-driven thermal changes can be giant near ferroic phase transitions in materials that display magnetic or electrical order. Here we demonstrate giant inverse barocaloric effects in the solid electrolyte AgI, near its superionic phase transition at ~420 K. Over a wide range of temperatures, hydrostatic pressure changes of 2.5 kbar yield large and reversible barocaloric effects, resulting in large values of refrigerant capacity. Moreover, the peak values of isothermal entropy change (60 J K-1 kg-1 or 0.34 J K-1 cm-3) and adiabatic temperature changes (18 K), which we identify for a starting temperature of 390 K, exceed all values previously recorded for barocaloric materials. Our work should therefore inspire the study of barocaloric effects in a wide range of solid electrolytes, as well as the parallel development of cooling devices. PMID- 29184056 TI - Functional mapping and annotation of genetic associations with FUMA. AB - A main challenge in genome-wide association studies (GWAS) is to pinpoint possible causal variants. Results from GWAS typically do not directly translate into causal variants because the majority of hits are in non-coding or intergenic regions, and the presence of linkage disequilibrium leads to effects being statistically spread out across multiple variants. Post-GWAS annotation facilitates the selection of most likely causal variant(s). Multiple resources are available for post-GWAS annotation, yet these can be time consuming and do not provide integrated visual aids for data interpretation. We, therefore, develop FUMA: an integrative web-based platform using information from multiple biological resources to facilitate functional annotation of GWAS results, gene prioritization and interactive visualization. FUMA accommodates positional, expression quantitative trait loci (eQTL) and chromatin interaction mappings, and provides gene-based, pathway and tissue enrichment results. FUMA results directly aid in generating hypotheses that are testable in functional experiments aimed at proving causal relations. PMID- 29184057 TI - The effects of PI3K-mediated signalling on glioblastoma cell behaviour. AB - The PI3K/Akt/mTOR signalling network is activated in almost 90% of all glioblastoma, the most common primary brain tumour, which is almost invariably lethal within 15 months of diagnosis. Despite intensive research, modulation of this signalling cascade has so far yielded little therapeutic benefit, suggesting that the role of the PI3K network as a pro-survival factor in glioblastoma and therefore a potential target in combination therapy should be re-evaluated. Therefore, we used two distinct pharmacological inhibitors that block signalling at different points of the cascade, namely, GDC-0941 (Pictilisib), a direct inhibitor of the near apical PI3K, and Rapamycin which blocks the side arm of the network that is regulated by mTOR complex 1. While both substances, at concentrations where they inhibit their primary target, have similar effects on proliferation and sensitisation for temozolomide-induced apoptosis, GDC-0941 appears to have a stronger effect on cellular motility than Rapamycin. In vivo GDC-0941 effectively retards growth of orthotopic transplanted human tumours in murine brains and significantly prolongs mouse survival. However, when looking at genetically identical cell populations that are in alternative states of differentiation, i.e. stem cell-like cells and their differentiated progeny, a more complex picture regarding the PI3K/Akt/mTOR pathway emerges. The pathway is differently regulated in the alternative cell populations and, while it contributes to the increased chemo-resistance of stem cell-like cells compared to differentiated cells, it only contributes to the motility of the latter. Our findings are the first to suggest that within a glioblastoma tumour the PI3K network can have distinct, cell-specific functions. These have to be carefully considered when incorporating inhibition of PI3K-mediated signals into complex combination therapies. PMID- 29184058 TI - Doxycycline induces apoptosis via ER stress selectively to cells with a cancer stem cell-like properties: importance of stem cell plasticity. AB - Tumor heterogeneity can be traced back to a small subset of cancer stem cells (CSCs), which can be derived from a single stem cell and show chemoresistance. Recent studies showed that CSCs are sensitive to mitochondrial targeting antibiotics such as doxycycline. However, little is known about how cancer cells undergo sphere formation and how antibiotics inhibit CSC proliferation. Here we show that under sphere-forming assay conditions, prostate cancer cells acquired CSC-like properties: promoted mitochondrial respiratory chain activity, expression of characteristic CSC markers and resistance to anticancer agents. Furthermore, those CSC-like properties could reversibly change depending on the culture conditions, suggesting some kinds of CSCs have plasticity in tumor microenvironments. The sphere-forming cells (i.e. cancer stem-like cells) showed increased contact between mitochondria and mitochondrial associated-endoplasmic reticulum (ER) membranes (MAM). Mitochondrial targeting doxycycline induced activating transcription factor 4 (ATF4) mediated expression of ER stress response and led to p53-upregulated modulator of apoptosis (PUMA)-dependent apoptosis only in the cancer stem-like cells. We also found that doxycycline effectively suppressed the sphere formation in vitro and blocked CD44v9 expressing tumor growth in vivo. In summary, these data provide new molecular findings that monolayer cancer cells acquire CSC-like properties in a reversible manner. These findings provide important insights into CSC biology and a potential new treatment of targeting mitochondria dependency. PMID- 29184060 TI - Predictive feedback to V1 dynamically updates with sensory input. AB - Predictive coding theories propose that the brain creates internal models of the environment to predict upcoming sensory input. Hierarchical predictive coding models of vision postulate that higher visual areas generate predictions of sensory inputs and feed them back to early visual cortex. In V1, sensory inputs that do not match the predictions lead to amplified brain activation, but does this amplification process dynamically update to new retinotopic locations with eye-movements? We investigated the effect of eye-movements in predictive feedback using functional brain imaging and eye-tracking whilst presenting an apparent motion illusion. Apparent motion induces an internal model of motion, during which sensory predictions of the illusory motion feed back to V1. We observed attenuated BOLD responses to predicted stimuli at the new post-saccadic location in V1. Therefore, pre-saccadic predictions update their retinotopic location in time for post-saccadic input, validating dynamic predictive coding theories in V1. PMID- 29184059 TI - Cardiopatch platform enables maturation and scale-up of human pluripotent stem cell-derived engineered heart tissues. AB - Despite increased use of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) for drug development and disease modeling studies, methods to generate large, functional heart tissues for human therapy are lacking. Here we present a "Cardiopatch" platform for 3D culture and maturation of hiPSC-CMs that after 5 weeks of differentiation show robust electromechanical coupling, consistent H-zones, I-bands, and evidence for T-tubules and M-bands. Cardiopatch maturation markers and functional output increase during culture, approaching values of adult myocardium. Cardiopatches can be scaled up to clinically relevant dimensions, while preserving spatially uniform properties with high conduction velocities and contractile stresses. Within window chambers in nude mice, cardiopatches undergo vascularization by host vessels and continue to fire Ca2+ transients. When implanted onto rat hearts, cardiopatches robustly engraft, maintain pre-implantation electrical function, and do not increase the incidence of arrhythmias. These studies provide enabling technology for future use of hiPSC-CM tissues in human heart repair. PMID- 29184061 TI - Metal-hydrogen systems with an exceptionally large and tunable thermodynamic destabilization. AB - Hydrogen is a key element in the energy transition. Hydrogen-metal systems have been studied for various energy-related applications, e.g., for their use in reversible hydrogen storage, catalysis, hydrogen sensing, and rechargeable batteries. These applications depend strongly on the thermodynamics of the metal hydrogen system. Therefore, tailoring the thermodynamics of metal-hydrogen interactions is crucial for tuning the properties of metal hydrides. Here we present a case of large metal hydride destabilization by elastic strain. The addition of small amounts of zirconium to yttrium leads to a compression of the yttrium lattice, which is maintained during (de)hydrogenation cycles. As a result, the equilibrium hydrogen pressure of YH2 <-> YH3 can be rationally and precisely tuned up to five orders of magnitude at room temperature. This allows us to realize a hydrogen sensor which indicates the ambient hydrogen pressure over four orders of magnitude by an eye-visible color change. PMID- 29184062 TI - Molecular architecture of potassium chloride co-transporter KCC2. AB - KCC2 is a neuron specific K+-Cl- co-transporter that controls neuronal chloride homeostasis, and is critically involved in many neurological diseases including brain trauma, epilepsies, autism and schizophrenia. Despite significant accumulating data on the biology and electrophysiological properties of KCC2, structure-function relationships remain poorly understood. Here we used calixarene detergent to solubilize and purify wild-type non-aggregated and homogenous KCC2. Specific binding of inhibitor compound VU0463271 was demonstrated using surface plasmon resonance (SPR). Mass spectrometry revealed glycosylations and phosphorylations as expected from functional KCC2. We show by electron microscopy (EM) that KCC2 exists as monomers and dimers in solution. Monomers are organized into "head" and "core" domains connected by a flexible "linker". Dimers are asymmetrical and display a bent "S-shape" architecture made of four distinct domains and a flexible dimerization interface. Chemical crosslinking in reducing conditions shows that disulfide bridges are involved in KCC2 dimerization. Moreover, we show that adding a tag to the C-terminus is detrimental to KCC2 function. We postulate that the conserved KCC2 C-ter may be at the interface of dimerization. Taken together, our findings highlight the flexible multi-domain structure of KCC2 with variable anchoring points at the dimerization interface and an important C-ter extremity providing the first in depth functional architecture of KCC2. PMID- 29184063 TI - Phloem-limited reoviruses universally induce sieve element hyperplasia and more flexible gateways, providing more channels for their movement in plants. AB - Virion distribution and ultrastructural changes induced by the infection of maize or rice with four different reoviruses were examined. Rice black streaked dwarf virus (RBSDV, genus Fijivirus), Rice ragged stunt virus (RRSV, genus Oryzavirus), and Rice gall dwarf virus (RGDV, genus Phytoreovirus) were all phloem-limited and caused cellular hyperplasia in the phloem resulting in tumors or vein swelling and modifying the cellular arrangement of sieve elements (SEs). In contrast, virions of Rice dwarf virus (RDV, genus Phytoreovirus) were observed in both phloem and mesophyll and the virus did not cause hyperplasia of SEs. The three phloem-limited reoviruses (but not RDV) all induced more flexible gateways at the SE-SE interfaces, especially the non-sieve plate interfaces. These flexible gateways were also observed for the first time at the cellular interfaces between SE and phloem parenchyma (PP). In plants infected with any of the reoviruses, virus-like particles could be seen within the flexible gateways, suggesting that these gateways may serve as channels for the movement of plant reoviruses with their large virions between SEs or between SEs and PP. SE hyperplasia and the increase in flexible gateways may be a universal strategy for the movement of phloem-limited reoviruses. PMID- 29184064 TI - Low-threshold optically pumped lasing in highly strained germanium nanowires. AB - The integration of efficient, miniaturized group IV lasers into CMOS architecture holds the key to the realization of fully functional photonic-integrated circuits. Despite several years of progress, however, all group IV lasers reported to date exhibit impractically high thresholds owing to their unfavourable bandstructures. Highly strained germanium with its fundamentally altered bandstructure has emerged as a potential low-threshold gain medium, but there has yet to be a successful demonstration of lasing from this seemingly promising material system. Here we demonstrate a low-threshold, compact group IV laser that employs a germanium nanowire under a 1.6% uniaxial tensile strain as the gain medium. The amplified material gain in strained germanium can sufficiently overcome optical losses at 83 K, thus allowing the observation of multimode lasing with an optical pumping threshold density of ~3.0 kW cm-2. Our demonstration opens new possibilities for group IV lasers for photonic-integrated circuits. PMID- 29184066 TI - The sensitivity of donor - acceptor charge transfer to molecular geometry in DAN NDI based supramolecular flower-like self-assemblies. AB - A charge-transfer (CT) complex self-assembled from an electron acceptor (NDI-EA: naphthalene diimide with appended diamine) and an electron donor (DAN: phosphonic acid-appended dialkoxynapthalene) in aqueous medium. The aromatic core of the NDI and the structure of DAN1 were designed to optimize the dispersive interactions (pi-pi and van der Waals interactions) in the DAN1-NDI-EA self-assembly, while the amino groups of NDI also interact with the phosphonic acid of DAN1 via electrostatic forces. This arrangement prevented crystallization and favored the directional growth of 3D flower nanostructures. This molecular geometry that is necessary for charge transfer to occur was further evidenced by using a mismatching DAN2 structure. The flower-shaped assembly was visualized by scanning electron and transmission electron microscopy. The formation of the CT complex was determined by UV-vis and cyclic voltammetry and the photoinduced electron transfer to produce the radical ion pair was examined by femtosecond laser transient absorption spectroscopic measurements. PMID- 29184065 TI - Zero-field edge plasmons in a magnetic topological insulator. AB - Incorporating ferromagnetic dopants into three-dimensional topological insulator thin films has recently led to the realisation of the quantum anomalous Hall effect. These materials are of great interest since they may support electrical currents that flow without resistance, even at zero magnetic field. To date, the quantum anomalous Hall effect has been investigated using low-frequency transport measurements. However, transport results can be difficult to interpret due to the presence of parallel conductive paths, or because additional non-chiral edge channels may exist. Here we move beyond transport measurements by probing the microwave response of a magnetised disk of Cr-(Bi,Sb)2Te3. We identify features associated with chiral edge plasmons, a signature that robust edge channels are intrinsic to this material system. Our results provide a measure of the velocity of edge excitations without contacting the sample, and pave the way for an on chip circuit element of practical importance: the zero-field microwave circulator. PMID- 29184067 TI - Identification of a neural crest stem cell niche by Spatial Genomic Analysis. AB - The neural crest is an embryonic population of multipotent stem cells that form numerous defining features of vertebrates. Due to lack of reliable techniques to perform transcriptional profiling in intact tissues, it remains controversial whether the neural crest is a heterogeneous or homogeneous population. By coupling multiplex single molecule fluorescence in situ hybridization with machine learning algorithm based cell segmentation, we examine expression of 35 genes at single cell resolution in vivo. Unbiased hierarchical clustering reveals five spatially distinct subpopulations within the chick dorsal neural tube. Here we identify a neural crest stem cell niche that centers around the dorsal midline with high expression of neural crest genes, pluripotency factors, and lineage markers. Interestingly, neural and neural crest stem cells express distinct pluripotency signatures. This Spatial Genomic Analysis toolkit provides a straightforward approach to study quantitative multiplex gene expression in numerous biological systems, while offering insights into gene regulatory networks via synexpression analysis. PMID- 29184068 TI - Heterologous expression reveals the biosynthesis of the antibiotic pleuromutilin and generates bioactive semi-synthetic derivatives. AB - The rise in antibiotic resistance is a major threat for human health. Basidiomycete fungi represent an untapped source of underexploited antimicrobials, with pleuromutilin-a diterpene produced by Clitopilus passeckerianus-being the only antibiotic from these fungi leading to commercial derivatives. Here we report genetic characterisation of the steps involved in pleuromutilin biosynthesis, through rational heterologous expression in Aspergillus oryzae coupled with isolation and detailed structural elucidation of the pathway intermediates by spectroscopic methods and comparison with synthetic standards. A. oryzae was further established as a platform for bio-conversion of chemically modified analogues of pleuromutilin intermediates, and was employed to generate a semi-synthetic pleuromutilin derivative with enhanced antibiotic activity. These studies pave the way for future characterisation of biosynthetic pathways of other basidiomycete natural products in ascomycete heterologous hosts, and open up new possibilities of further chemical modification for the growing class of potent pleuromutilin antibiotics. PMID- 29184069 TI - Phosphorylated exogenous alpha-synuclein fibrils exacerbate pathology and induce neuronal dysfunction in mice. AB - Approximately 90% of alpha-synuclein (alpha-Synuclein) deposited in Lewy bodies is phosphorylated at serine 129 suggesting that the accumulation of phosphorylated alpha-Synuclein is critical in the pathogenesis of Parkinson's disease. However, in vivo experiments addressing the role of phosphorylated alpha Synuclein in the progression of Parkinson's disease have produced equivocal data. To clarify a role of Ser129 phosphorylation of alpha-Synuclein in pathology progression we performed stereotaxic injections targeting the mouse striatum with three fibrilar alpha-Synuclein types: wt-fibrils, phosphorylated S129 fibrils and, phosphorylation incompetent, S129A fibrils. Brain inoculation of all three fibrilar types caused seeding of the endogenous alpha-Synuclein. However, phosphorylated fibrils triggered the formation of more alpha-Synuclein inclusions in the Substantia Nigra pars compacta (SNpc), exacerbated pathology in the cortex and caused dopaminergic neuronal loss and fine motor impairment as early as 60 days post injection. Phosphorylated fibril injections also induced early changes in the innate immune response including alterations in macrophage recruitment and IL-10 release. Our study further shows that S129 phosphorylation facilitated alpha-Synuclein fibril uptake by neurons. Our results highlight the role of phosphorylated fibrilar alpha-Synuclein in pathology progression in vivo and suggest that targeting phosphorylated alpha-Synuclein assemblies might be important for delaying inclusion formation. PMID- 29184070 TI - Improved outcome for AML patients over the years 2000-2014. AB - Few recent studies from registries have reported an improvement in overall survival of younger patients with acute myeloid leukemia (AML). However, reasons for this improvement are not defined. We analyzed the therapeutic course and outcome of 976 patients treated by intensive chemotherapy between 2000 and 2014. The number of patients receiving allogeneic stem cell transplantation in first or second response significantly increased over time whereas autologous transplantation was progressively abandoned. In the 513 younger patients, there were no differences in first complete response, induction failure, incidence of relapse, or non-relapse mortality over time. The period of time was significantly associated with a better overall survival especially in 2010-2014. The 2010-2014 period effect was still significant in multivariate analysis and was independent of allogeneic stem cell transplantation. In the 463 older patients, there was a significant interaction between the period and leukocytosis in multivariate analysis meaning that the 2010-2014 period had only an impact in patients with white blood cell count >50 giga/L for response and overall survival. Progresses have been made in each phase of the therapeutic course of younger AML patients resulting in survival improvement. In older patients, the outcome of hyperleukocytic patients has significantly improved in 2010-2014. PMID- 29184071 TI - Preventive Trichuris suis ova (TSO) treatment protects immunocompetent rabbits from DSS colitis but may be detrimental under conditions of immunosuppression. AB - Trichuris suis ova (TSO) have been tested for therapeutic application in inflammatory bowel diseases (IBD) yet understanding of the underlying mechanisms and safety in an immunocompromised host is limited due to lack of a suitable animal model. We used a recently established rabbit model of dextran sodium sulphate (DSS) induced colitis to study the efficacy, mechanisms and safety of TSO therapy in immunocompetent and immunosuppressed animals. TSO treatment prevented the DSS induced weight loss, delayed the onset of DSS induced symptoms by 2 days and significantly reduced the disease activity (DAI). TSO treatment protected caecal histology and prevented the colitis-associated loss in faecal microbiota diversity. Mainly the transcriptome of lamina propria mononuclear cells (LPMC) was affected by TSO treatment, showing dampened innate and adaptive inflammatory responses. The protective effect of TSO was lost in immunosuppressed rabbits, where TSO exacerbated colitis. Our data show that preventive TSO treatment ameliorates colitis severity in immunocompetent rabbits, modulates LPMC immune responses and reduces faecal dysbiosis. In contrast, the same TSO treatment exacerbates colitis in immunosuppressed animals. Our data provide further evidence for a therapeutic effect of TSO in IBD, yet caution is required with regard to TSO treatment in immunosuppressed patients. PMID- 29184072 TI - Adrenomedullin protects Leydig cells against lipopolysaccharide-induced oxidative stress and inflammatory reaction via MAPK/NF-kappaB signalling pathways. AB - This study aimed to explore the possible benefits of adrenomedullin (ADM) in preventing oxidative stress and inflammation by using an in vitro primary culture model of rat Leydig cells exposed to lipopolysaccharide (LPS). Cell proliferation was detected through CCK-8 and BrdU incorporation assays. ROS were determined with a DCFDA kit, and cytokine concentrations were measured with ELISA assay kits. Protein production was examined by immunohistochemical staining and Western blot, and gene expression was observed through RT-qPCR. Results revealed that ADM significantly reduced LPS-induced cytotoxicity, and pretreatment with ADM significantly suppressed ROS overproduction and decreased 4-HNE and 8-OHdG expression levels and concentrations. ADM pretreatment also significantly attenuated the overactivation of enzymatic antioxidants, namely, superoxide dismutase, catalase, thioredoxin reductase, glutathione peroxidase, glutathione reductase and glutathione-S-transferase. ADM supplementation reversed the significantly increased gene expression levels and concentrations of TNF-alpha, IL-1beta, TGF-beta1, MCP-1 and MIF. ADM pretreatment significantly inhibited the gene expression and protein production of TLR-2 and 4. Furthermore, ADM pretreatment markedly reduced the phosphorylation of JNK, ERK 1/2 and p38, phosphorylation and degradation of IkappaBalpha and nuclear translocation of p65. Our findings demonstrated that ADM protects Leydig cells from LPS-induced oxidative stress and inflammation, which might be associated with MAPK/NF-kappaB signalling pathways. PMID- 29184073 TI - Simple spatial scaling rules behind complex cities. AB - Although most of wealth and innovation have been the result of human interaction and cooperation, we are not yet able to quantitatively predict the spatial distributions of three main elements of cities: population, roads, and socioeconomic interactions. By a simple model mainly based on spatial attraction and matching growth mechanisms, we reveal that the spatial scaling rules of these three elements are in a consistent framework, which allows us to use any single observation to infer the others. All numerical and theoretical results are consistent with empirical data from ten representative cities. In addition, our model can also provide a general explanation of the origins of the universal super- and sub-linear aggregate scaling laws and accurately predict kilometre level socioeconomic activity. Our work opens a new avenue for uncovering the evolution of cities in terms of the interplay among urban elements, and it has a broad range of applications. PMID- 29184074 TI - Scaling relationships and theory for vibrational frequencies of adsorbates on transition metal surfaces. AB - Adsorbate vibrational excitations are an important fingerprint of molecule/surface interactions, affecting temperature contributions to the free energy and impacting reaction rate and equilibrium constants. Furthermore, vibrational spectra aid in identifying species and adsorption sites present in experimental studies. Despite their importance, knowledge of how adsorbate frequencies scale across materials is lacking. Here, by combining previously reported experimental data and our own density-functional theory calculations, we reveal linear correlations between vibrational frequencies of adsorbates on transition metal surfaces. Through effective-medium theory, linear muffin-tin orbital theory, and the d-band model, we rationalize the squares of the frequencies to be fundamentally linear in their scaling across transition metal surfaces. We identify the adsorbate-binding energy as a descriptor for certain molecular vibrations and rigorously relate errors in frequencies to errors in adsorption energies. We also discuss the impact of scaling on surface thermochemistry and adsorbate coverage. PMID- 29184075 TI - Subdiffusion via dynamical localization induced by thermal equilibrium fluctuations. AB - We reveal the mechanism of subdiffusion which emerges in a straightforward, one dimensional classical nonequilibrium dynamics of a Brownian ratchet driven by both a time-periodic force and Gaussian white noise. In a tailored parameter set for which the deterministic counterpart is in a non-chaotic regime, subdiffusion is a long-living transient whose lifetime can be many, many orders of magnitude larger than characteristic time scales of the setup thus being amenable to experimental observations. As a reason for this subdiffusive behaviour in the coordinate space we identify thermal noise induced dynamical localization in the velocity (momentum) space. This novel idea is distinct from existing knowledge and has never been reported for any classical or quantum system. It suggests reconsideration of generally accepted opinion that subdiffusion is due to broad distributions or strong correlations which reflect disorder, trapping, viscoelasticity of the medium or geometrical constraints. PMID- 29184076 TI - Deciphering how Cpl-7 cell wall-binding repeats recognize the bacterial peptidoglycan. AB - Endolysins, the cell wall lytic enzymes encoded by bacteriophages to release the phage progeny, are among the top alternatives to fight against multiresistant pathogenic bacteria; one of the current biggest challenges to global health. Their narrow range of susceptible bacteria relies, primarily, on targeting specific cell-wall receptors through specialized modules. The cell wall-binding domain of Cpl-7 endolysin, made of three CW_7 repeats, accounts for its extended range of substrates. Using as model system the cell wall-binding domain of Cpl-7, here we describe the molecular basis for the bacterial cell wall recognition by the CW_7 motif, which is widely represented in sequences of cell wall hydrolases. We report the crystal and solution structure of the full-length domain, identify N-acetyl-D-glucosaminyl-(beta1,4)-N-acetylmuramyl-L-alanyl-D-isoglutamine (GMDP) as the peptidoglycan (PG) target recognized by the CW_7 motifs, and characterize feasible GMDP-CW_7 contacts. Our data suggest that Cpl-7 cell wall-binding domain might simultaneously bind to three PG chains, and also highlight the potential use of CW_7-containing lysins as novel anti-infectives. PMID- 29184077 TI - The structural, magnetic and optical properties of TMn@(ZnO)42 (TM = Fe, Co and Ni) hetero-nanostructure. AB - The magnetic transition-metal (TM) @ oxide nanoparticles have been of great interest due to their wide range of applications, from medical sensors in magnetic resonance imaging to photo-catalysis. Although several studies on small clusters of TM@oxide have been reported, the understanding of the physical electronic properties of TMn@(ZnO)42 is far from sufficient. In this work, the electronic, magnetic and optical properties of TMn@(ZnO)42 (TM = Fe, Co and Ni) hetero-nanostructure are investigated using the density functional theory (DFT). It has been found that the core-shell nanostructure Fe13@(ZnO)42, Co15@(ZnO)42 and Ni15@(ZnO)42 are the most stable structures. Moreover, it is also predicted that the variation of the magnetic moment and magnetism of Fe, Co and Ni in TMn@ZnO42 hetero-nanostructure mainly stems from effective hybridization between core TM-3d orbitals and shell O-2p orbitals, and a magnetic moment inversion for Fe15@(ZnO)42 is investigated. Finally, optical properties studied by calculations show a red shift phenomenon in the absorption spectrum compared with the case of (ZnO)48. PMID- 29184078 TI - Function of capric acid in cyclophosphamide-induced intestinal inflammation, oxidative stress, and barrier function in pigs. AB - The small intestine is not only critical for nutrient absorption, but also serves as an important immune organ. Medium-chain fatty acids have nutritional and metabolic effects and support the integrity of the intestinal epithelium. However, their roles in intestinal immunity in pigs are not fully understood. We investigated the effects of a medium-chain fatty acid, capric acid, on intestinal oxidative stress, inflammation, and barrier function in porcine epithelial cells and miniature pigs after treatment with the immune suppressant cyclophosphamide. Capric acid alleviated inflammatory cytokine production (TNF-alpha and IL-6) and related gene expression (NF-kappaB, TNF-alpha, IFN-gamma), alleviated oxidative stress (GSSG/GSH ratio, H2O2, and malondialdehyde), and increased oxidative stress-related gene expression (SOD1 and GCLC) in cyclophosphamide-treated IPEC J2 cells. The permeability of FD-4 and expression of ZO-1 and OCLN in cyclophosphamide-treated IPEC-J2 cells were reduced by capric acid. Dietary capric acid reduced TNF-alpha, IL-6, and MDA levels and increased SOD, GPx, and the expression of genes related to pro-inflammatory, oxidative stress, and intestinal barrier functions in cyclophosphamide-treated miniature pigs. These results revealed that capric acid has protective effects against cyclophosphamide induced small intestinal dysfunction in pigs. PMID- 29184079 TI - Virus-host protein-protein interactions of mycobacteriophage Giles. AB - Mycobacteriophage are viruses that infect mycobacteria. More than 1,400 mycobacteriophage genomes have been sequenced, coding for over one hundred thousand proteins of unknown functions. Here we investigate mycobacteriophage Giles-host protein-protein interactions (PPIs) using yeast two-hybrid screening (Y2H). A total of 25 reproducible PPIs were found for a selected set of 10 Giles proteins, including a putative virion assembly protein (gp17), the phage integrase (gp29), the endolysin (gp31), the phage repressor (gp47), and six proteins of unknown function (gp34, gp35, gp54, gp56, gp64, and gp65). We note that overexpression of the proteins is toxic to M. smegmatis, although whether this toxicity and the associated changes in cellular morphology are related to the putative interactions revealed in the Y2H screen is unclear. PMID- 29184080 TI - Factors affecting pitch discrimination performance in a cohort of extensively phenotyped healthy volunteers. AB - Despite efforts to characterize the different aspects of musical abilities in humans, many elements of this complex area remain unknown. Musical abilities are known to be associated with factors like intelligence, training, and sex, but a comprehensive evaluation of the simultaneous impact of multiple factors has not yet been performed. Here, we assessed 918 healthy volunteers for pitch discrimination abilities-their ability to tell two tones close in pitch apart. We identified the minimal threshold that the participants could detect, and we found that better performance was associated with higher intelligence, East Asian ancestry, male sex, younger age, formal music training-especially before age 6 and English as the native language. All these factors remained significant when controlling for the others, with general intelligence, musical training, and male sex having the biggest impacts. We also performed a small GWAS and gene-based collapsing analysis, identifying no significant associations. Future genetic studies of musical abilities should involve large sample sizes and an unbiased genome-wide approach, with the factors highlighted here included as important covariates. PMID- 29184081 TI - Allosteric inhibitor remotely modulates the conformation of the orthestric pockets in mutant IDH2/R140Q. AB - Neomorphic mutation R140Q in the metabolic enzyme isocitrate dehydrogenase 2 (IDH2) is found to be a driver mutation in cancers. Recent studies revealed that allosteric inhibitors could selectively inhibit IDH2/R140Q and induce differentiation of TF-1 erythroleukemia and primary human AML cells. However, the allosteric inhibition mechanism is not very clear. Here, we report the results from computational studies that AGI-6780 binds tightly with the divalent cation binding helices at the homodimer interface and prevents the transition of IDH2/R140Q homodimer to a closed conformation that is required for catalysis, resulting in the decrease of the binding free energy of NADPHs. If the allosteric inhibitor is removed, the original open catalytic center of IDH2/R140Q will gradually reorganize to a quasi-closed conformation and the enzymatic activity might recover. Unlike IDH2/R140Q, AGI-6780 locks one monomer of the wild-type IDH2 in an inactive open conformation and the other in a half-closed conformation, which can be used to explain the selectivity of AGI-6780. Our results suggest that conformational changes are the primary contributors to the inhibitory potency of the allosteric inhibitor. Our study will also facilitate the understanding of the inhibitory and selective mechanisms of AG-221 (a promising allosteric inhibitor that has been approved by FDA) for mutant IDH2. PMID- 29184082 TI - Identification of a histone family gene signature for predicting the prognosis of cervical cancer patients. AB - Heterogeneity in terms of tumor characteristics, prognosis, and survival among cancer patients is an unsolved issue. Here, we systematically analyzed the aberrant expression patterns of cervical cancer using RNA-Seq data from The Cancer Genome Atlas (TCGA). We incorporated gene profiling, molecular signatures, functional and pathway information with gene set enrichment and protein-protein interaction (PPI) network analysis, to identify sub-networks of genes. Those identified genes relating to DNA replication and DNA repair-mediated signaling pathways associated with systemic lupus erythematosus (SLE). Next, we combined cross-validated prognostic scores to build an integrated prognostic model for survival prediction. The combined approach revealed that the DNA repair-mediated including the functional interaction module of 18 histone genes (Histone cluster 1 H2A, B and H4), were significantly correlated with the survival rate. Furthermore, five of these histone genes were highly expressed in three cervical cancer cohorts from the Oncomine database. Comparison of high and low histone variant-expressing human cervical cancer cell lines revealed different responses to DNA damage, suggesting protective functions of histone genes against DNA damage. Collectively, we provide evidence that two SLE-associated gene sets (HIST1H2BD and HIST1H2BJ; and HIST1H2BD, HIST1H2BJ, HIST1H2BH, HIST1H2AM and HIST1H4K) can be used as prognostic factors for survival prediction among cervical cancer patients. PMID- 29184083 TI - The power of monitoring: optimizing survey designs to detect occupancy changes in a rare amphibian population. AB - Biodiversity conservation requires reliable species assessments and rigorously designed surveys. However, determining the survey effort required to reliably detect population change can be challenging for rare, cryptic and elusive species. We used a tropical bromeliad-dwelling frog as a model system to explore a cost-effective sampling design that optimizes the chances of detecting a population decline. Relatively few sampling visits were needed to estimate occupancy and detectability with good precision, and to detect a 30% change in occupancy with 80% power. Detectability was influenced by observer expertise, which therefore also had an effect on the sampling design - less experienced observers require more sampling visits to detect the species. Even when the sampling design provides precise parameter estimates, only moderate to large changes in occupancy will be detected with reliable power. Detecting a population change of 15% or less requires a large number of sites to be surveyed, which might be unachievable for range-restricted species occurring at relatively few sites. Unless there is high initial occupancy, rare and cryptic species will be particularly challenging when it comes to detecting small population changes. This may be a particular issue for long-term monitoring of amphibians which often display low detectability and wide natural fluctuations. PMID- 29184084 TI - The flexibility and dynamics of the tubules in the endoplasmic reticulum. AB - The endoplasmic reticulum (ER) is a single organelle in eukaryotic cells that extends throughout the cell and is involved in a large number of cellular functions. Using a combination of fixed and live cells (human MRC5 lung cells) in diffraction limited and super-resolved fluorescence microscopy (STORM) experiments, we determined that the average persistence length of the ER tubules was 3.03 +/- 0.24 MUm. Removing the branched network junctions from the analysis caused a slight increase in the average persistence length to 4.71 +/- 0.14 MUm, and provides the tubule's persistence length with a moderate length scale dependence. The average radius of the tubules was 44.1 +/- 3.2 nm. The bending rigidity of the ER tubule membranes was found to be 10.9 +/- 1.2 kT (17.0 +/- 1.3 kT without branch points). We investigated the dynamic behaviour of ER tubules in live cells, and found that the ER tubules behaved like semi-flexible fibres under tension. The majority of the ER tubules experienced equilibrium transverse fluctuations under tension, whereas a minority number of them had active super diffusive motions driven by motor proteins. Cells thus actively modulate the dynamics of the ER in a well-defined manner, which is expected in turn to impact on its many functions. PMID- 29184085 TI - Diverse Changes of Circulating Fibroblast Growth Factor 21 Levels in Hepatitis B Virus-Related Diseases. AB - Fibroblast growth factor 21 (FGF21), a stress-induced hormone in the liver, has been shown the protective functions in pathological conditions. The study investigated the association of circulating FGF21 with hepatitis B virus (HBV) infection and its related diseases. Serum FGF21 levels were measured in 33 acute hepatitis B (AHB), 75 chronic hepatitis B (CHB) and 66 CHB patients with advanced liver diseases including liver cirrhosis, acute-on-chronic liver failure (ALCF) and hepatocellular carcinoma (HCC) together with 200 age- and BMI-matched healthy controls. FGF21 levels were significantly increased in AHB patients and rapidly returned to normal levels after treatment. FGF21 levels reflected the degree of liver injury caused by AHB. However, serum FGF21 levels were decreased in CHB patients especially in those who developed cirrhosis and were associated with hepatic protein synthesis capacity. Serum FGF21 in CHB patients were increased with the occurrence of ACLF. Notably, in CHB patients who developed HCC, serum FGF21 exhibited a dramatic increase, which may provide important information on monitoring tumorigenesis in CHB patients. In conclusion, we revealed the diverse changes of circulating FGF21 in HBV-related diseases. FGF21 may be a useful biomarker in monitoring the tumorigenesis in patients with CHB. PMID- 29184086 TI - Characteristic of entire corneal topography and tomography for the detection of sub-clinical keratoconus with Zernike polynomials using Pentacam. AB - The study aimed to characterize the entire corneal topography and tomography for the detection of sub-clinical keratoconus (KC) with a Zernike application method. Normal subjects (n = 147; 147 eyes), sub-clinical KC patients (n = 77; 77 eyes), and KC patients (n = 139; 139 eyes) were imaged with the Pentacam HR system. The entire corneal data of pachymetry and elevation of both the anterior and posterior surfaces were exported from the Pentacam HR software. Zernike polynomials fitting was used to quantify the 3D distribution of the corneal thickness and surface elevation. The root mean square (RMS) values for each order and the total high-order irregularity were calculated. Multimeric discriminant functions combined with individual indices were built using linear step discriminant analysis. Receiver operating characteristic curves determined the diagnostic accuracy (area under the curve, AUC). The 3rd-order RMS of the posterior surface (AUC: 0.928) obtained the highest discriminating capability in sub-clinical KC eyes. The multimeric function, which consisted of the Zernike fitting indices of corneal posterior elevation, showed the highest discriminant ability (AUC: 0.951). Indices generated from the elevation of posterior surface and thickness measurements over the entire cornea using the Zernike method based on the Pentacam HR system were able to identify very early KC. PMID- 29184087 TI - A half-site multimeric enzyme achieves its cooperativity without conformational changes. AB - Cooperativity is a feature many multimeric proteins use to control activity. Here we show that the bacterial heptose isomerase GmhA displays homotropic positive and negative cooperativity among its four protomers. Most similar proteins achieve this through conformational changes: GmhA instead employs a delicate network of hydrogen bonds, and couples pairs of active sites controlled by a unique water channel. This network apparently raises the Lewis acidity of the catalytic zinc, thus increasing the activity at one active site at the cost of preventing substrate from adopting a reactive conformation at the paired negatively cooperative site - a "half-site" behavior. Our study establishes the principle that multimeric enzymes can exploit this cooperativity without conformational changes to maximize their catalytic power and control. More broadly, this subtlety by which enzymes regulate functions could be used to explore new inhibitor design strategies. PMID- 29184088 TI - Comparison of two-year outcomes after photodynamic therapy with ranibizumab or aflibercept for polypoidal choroidal vasculopathy. AB - Photodynamic therapy (PDT) combined with intravitreal anti-vascular endothelial growth factor (VEGF) agents is currently the first-line treatment for polypoidal choroidal vasculopathy (PCV), along with anti-VEGF monotherapy. In this study, 100 eyes with treatment-naive PCV were initially treated with PDT combined with intravitreal ranibizumab (IVR; n = 57) or aflibercept (IVA; n = 43). We compared two-year outcomes between these two groups and investigated factors associated with visual improvement and retreatment over 24 months. Best-corrected visual acuity (BCVA) was significantly improved in both groups (P < 0.001) at 24 months. Multiple regression analysis revealed that visual improvement at 24 months was associated with female (P = 0.030), worse baseline BCVA (P = 3.0 * 10-6), smaller greatest linear dimension (GLD; P = 2.0 * 10-4), and treatment with IVA rather than IVR (P = 0.016). Multiple logistic regression analysis revealed that absence of retreatment was associated with younger age (P = 2.2 * 10-4), female (P = 1.2 * 10-3), and the non-risk variants of ARMS2 A69S (P = 6.0 * 10-4). Although there were no significant differences in the retreatment rate between the two groups, PDT/IVA may be superior to PDT/IVR in terms of visual improvement at 24 months. PMID- 29184089 TI - Topological States Characterized by Mirror Winding Numbers in Graphene with Bond Modulation. AB - Localized electrons appear at the zigzag-shaped edge of graphene due to quantum interference. Here we propose a way for harnessing the edge electronic states to make them mobile, by incorporating a topological view point. The manipulation required is to introduce a pattern of strong-weak bonds between neighboring carbon atoms, and to put side by side two graphene sheets with strong-weak alternation conjugating to each other. The electrons with up and down pseudospins propagate in opposite directions at the interface, similar to the prominent quantum spin Hall effect. The system is characterized by a topological index, the mirror winding number, with its root lying in the Su-Schrieffer-Heeger model for polymer. Taking this point of view, one is rewarded by several ways for decorating graphene edge which result in similar mobile electronic states with topological protection. This work demonstrates that celebrated nanotechnology can be used to derive topological states. PMID- 29184090 TI - Thyroid hormones derivatives reduce proliferation and induce cell death and DNA damage in ovarian cancer. AB - Ovarian cancer is a highly aggressive disease and novel treatments are required. Thyroid hormones binding to alphavbeta3 integrin produced growth-promoting activities in ovarian cancer and we hypothesized that natural thyroid hormone derivatives may antagonize these actions. The effect of three antagonists, tetraiodoacetic acid (tetrac), triiodothyroacetic acid (triac) and 3 iodothyronamine (T1AM), on cell proliferation, cell death and DNA damage was studied in two ovarian cancer cell lines (OVCAR3 and A2780), normal hamster ovary control cells (CHOK1) and alphavbeta3-deficient or transfected HEK293 cells. A differential inhibition of cell proliferation was observed in ovarian cancer cells compared to CHOK1. In OVCAR3, an induction of cell cycle regulators was further shown. Apoptosis was confirmed (annexin-PI, SubG1/cell-cycle, apoptotic genes, caspase-3 and poly ADP ribose polymerase-1 (PARP-1) cleavage) and was reversed by a pan-caspase inhibitor. Induction in apoptosis inducing factor (AIF) was observed, suggesting a parallel caspase-independent mechanism. Integrin involvement in triac/T1AM apoptotic action was shown in alphavbeta3-transfected HEK293 cells. Lastly, in ovarian cancer models, key proteins that coordinate recognition of DNA damage, ataxia-telangiectasia mutated (ATM) and PARP-1, were induced. To conclude, the cytotoxic potential of thyroid hormone derivatives, tetrac, triac and T1AM, in ovarian cancer may provide a much-needed novel therapeutic approach. PMID- 29184091 TI - 2D/3D Microanalysis by Energy Dispersive X-ray Absorption Spectroscopy Tomography. AB - X-ray spectroscopic techniques have proven to be particularly useful in elucidating the molecular and electronic structural information of chemically heterogeneous and complex micro- and nano-structured materials. However, spatially resolved chemical characterization at the micrometre scale remains a challenge. Here, we report the novel hyperspectral technique of micro Energy Dispersive X-ray Absorption Spectroscopy (MUED-XAS) tomography which can resolve in both 2D and 3D the spatial distribution of chemical species through the reconstruction of XANES spectra. To document the capability of the technique in resolving chemical species, we first analyse a sample containing 2-30 MUm grains of various ferrous- and ferric-iron containing minerals, including hypersthene, magnetite and hematite, distributed in a light matrix of a resin. We accurately obtain the XANES spectra at the Fe K-edge of these four standards, with spatial resolution of 3 MUm. Subsequently, a sample of ~1.9 billion-year-old microfossil from the Gunflint Formation in Canada is investigated, and for the first time ever, we are able to locally identify the oxidation state of iron compounds encrusting the 5 to 10 MUm microfossils. Our results highlight the potential for attaining new insights into Precambrian ecosystems and the composition of Earth's earliest life forms. PMID- 29184092 TI - Simple eco-friendly synthesis of the surfactant free SnS nanocrystal toward the photoelectrochemical cell application. AB - A simple, low cost, non-toxic and eco-friendly pathway for synthesizing efficient sunlight-driven tin sulfide photocatalyst was studied. SnS nanocrystals were prepared by using mechanical method. The bulk SnS was obtained by evaporation of SnS nanocrystal solution. The synthesized samples were characterized by using XRD, SEM, TEM, UV-vis, and Raman analyses. Well crystallized SnS nanocrystals were verified and the electrochemical characterization was also performed under visible light irradiation. The SnS nanocrystals have shown remarkable photocurrent density of 7.6 mA cm-2 under 100 mW cm-2 which is about 10 times larger than that of the bulk SnS under notably stable operation conditions. Furthermore, the SnS nanocrystals presented higher stability than the bulk form. The IPCE(Incident photon to current conversion efficiency) of 9.3% at 420 nm was obtained for SnS nanocrystal photoanode which is strikingly higher than that of bulk SnS, 0.78%. This work suggests that the enhancement of reacting area by using SnS nanocrystal absorbers could give rise to the improvement of photoelectrochemical cell efficiency. PMID- 29184093 TI - Intrapartum antibiotics for GBS prophylaxis alter colonization patterns in the early infant gut microbiome of low risk infants. AB - Early life microbial colonization and succession is critically important to healthy development with impacts on metabolic and immunologic processes throughout life. A longitudinal prospective cohort was recruited from midwifery practices to include infants born at full term gestation to women with uncomplicated pregnancies. Here we compare bacterial community succession in infants born vaginally, with no exposure to antibiotics (n = 53), with infants who were exposed to intrapartum antibiotic prophylaxis (IAP) for Group B Streptococcus (GBS; n = 14), and infants born by C-section (n = 7). Molecular profiles of the 16 S rRNA genes indicate that there is a delay in the expansion of Bifidobacterium, which was the dominate infant gut colonizer, over the first 12 weeks and a persistence of Escherichia when IAP for GBS exposure is present during vaginal labour. Longer duration of IAP exposure increased the magnitude of the effect on Bifidobacterium populations, suggesting a longer delay in microbial community maturation. As with prior studies, we found altered gut colonisation following C-section that included a notable lack of Bacteroidetes. This study found that exposure of infants to IAP for GBS during vaginal birth affected aspects of gut microbial ecology that, although dramatic at early time points, disappeared by 12 weeks of age in most infants. PMID- 29184094 TI - Dynamics of Intact MexAB-OprM Efflux Pump: Focusing on the MexA-OprM Interface. AB - Antibiotic efflux is one of the most critical mechanisms leading to bacterial multidrug resistance. Antibiotics are effluxed out of the bacterial cell by a tripartite efflux pump, a complex machinery comprised of outer membrane, periplasmic adaptor, and inner membrane protein components. Understanding the mechanism of efflux pump assembly and its dynamics could facilitate discovery of novel approaches to counteract antibiotic resistance in bacteria. We built here an intact atomistic model of the Pseudomonas aeruginosa MexAB-OprM pump in a Gram negative membrane model that contained both inner and outer membranes separated by a periplasmic space. All-atom molecular dynamics (MD) simulations confirm that the fully assembled pump is stable in the microsecond timescale. Using a combination of all-atom and coarse-grained MD simulations and sequence covariation analysis, we characterized the interface between MexA and OprM in the context of the entire efflux pump. These analyses suggest a plausible mechanism by which OprM is activated via opening of its periplasmic aperture through a concerted interaction with MexA. PMID- 29184095 TI - Exteroceptive expectations modulate interoceptive processing: repetition suppression effects for visual and heartbeat evoked potentials. AB - Interoception refers to the signaling of internal bodily commands. Here, we explore repetition suppression of intero- and exteroceptive neural markers to test whether the perception and predictability of exteroceptive stimulus material affects their expression. Participants completed a repetition suppression paradigm in which angry or neutral facial expressions repeated or alternated. Participants received either an implicit (experiment 1) or explicit (experiment 2) cue enabling the formation of expectations regarding the upcoming facial expression. We measured the heartbeat-evoked potential (HEP) indexing cardiac processing and visual evoked potentials (VEP) in response to viewing the second (repeated or alternated) face. Repeating angry facial expressions produced repetition suppression of both HEP and VEP amplitude while repeating neutral expressions led to repetition enhancement of HEP amplitude. This effect was magnified when participants were explicitly aware of predictive cues. Furthermore, repetition suppression of HEP amplitude correlated with neural attenuation of VEP activity. Results highlight repetition effects for interoceptive as well as exteroceptive neural markers and support top-down, expectation-based accounts of the phenomenon. Furthermore, results demonstrate that the perception of exteroceptive stimulus information has an effect on the processing of interoceptive signals and suggest a direct neural connection between the processing of external and internal sensory information. PMID- 29184096 TI - Development of corticostriatal connectivity constrains goal-directed behavior during adolescence. AB - When pursuing high-value goals, mature individuals typically titrate cognitive performance according to environmental demands. However, it remains unclear whether adolescents similarly integrate value-based goals to selectively enhance goal-directed behavior. We used a value-contingent cognitive control task during fMRI to assess how stakes-the value of a prospective outcome-modulate flexible goal-directed behavior and underlying neurocognitive processes. Here we demonstrate that while adults enhance performance during high stakes, adolescents perform similarly during low and high stakes conditions. The developmental emergence of value-contingent performance is mediated by connectivity between the striatum and prefrontal cortex; this connectivity selectively increases during high stakes and with age. These findings suggest that adolescents may not benefit from high stakes to the same degree adults do-a behavioral profile that may be constrained by ongoing maturation of corticostriatal connectivity. We propose that late development of corticostriatal connectivity sets the stage for optimal goal-directed behavior. PMID- 29184097 TI - Csl2, a novel chimeric bacteriophage lysin to fight infections caused by Streptococcus suis, an emerging zoonotic pathogen. AB - Streptococcus suis is a Gram-positive bacterium that infects humans and various animals, causing human mortality rates ranging from 5 to 20%, as well as important losses for the swine industry. In addition, there is no effective vaccine for S. suis and isolates with increasing antibiotic multiresistance are emerging worldwide. Facing this situation, wild type or engineered bacteriophage lysins constitute a promising alternative to conventional antibiotics. In this study, we have constructed a new chimeric lysin, Csl2, by fusing the catalytic domain of Cpl-7 lysozyme to the CW_7 repeats of LySMP lysin from an S. suis phage. Csl2 efficiently kills different S. suis strains and shows noticeable activity against a few streptococci of the mitis group. Specifically, 15 ug/ml Csl2 killed 4.3 logs of S. suis serotype 2 S735 strain in 60 min, in a buffer containing 150 mM NaCl and 10 mM CaCl2, at pH 6.0. We have set up a protocol to form a good biofilm with the non-encapsulated S. suis mutant strain BD101, and the use of 30 ug/ml Csl2 was enough for dispersing such biofilms and reducing 1-2 logs the number of planktonic bacteria. In vitro results have been validated in an adult zebrafish model of infection. PMID- 29184098 TI - Counter-intuitive influence of Himalayan river morphodynamics on Indus Civilisation urban settlements. AB - Urbanism in the Bronze-age Indus Civilisation (~4.6-3.9 thousand years before the present, ka) has been linked to water resources provided by large Himalayan river systems, although the largest concentrations of urban-scale Indus settlements are located far from extant Himalayan rivers. Here we analyse the sedimentary architecture, chronology and provenance of a major palaeochannel associated with many of these settlements. We show that the palaeochannel is a former course of the Sutlej River, the third largest of the present-day Himalayan rivers. Using optically stimulated luminescence dating of sand grains, we demonstrate that flow of the Sutlej in this course terminated considerably earlier than Indus occupation, with diversion to its present course complete shortly after ~8 ka. Indus urban settlements thus developed along an abandoned river valley rather than an active Himalayan river. Confinement of the Sutlej to its present incised course after ~8 ka likely reduced its propensity to re-route frequently thus enabling long-term stability for Indus settlements sited along the relict palaeochannel. PMID- 29184099 TI - Accurate quantification of homologous recombination in zebrafish: brca2 deficiency as a paradigm. AB - Homologous Recombination (HR) repair is essential for repairing DNA double strand breaks (DSB) in dividing cells and preventing tumorigenesis. BRCA2 plays an important role in HR by recruiting the DNA recombinase RAD51 to the DSB. Despite being a popular model organism in genetic and cancer research, knowledge on the conservation of the HR pathway and function of zebrafish Brca2 is limited. To evaluate this, we developed a Rad51 foci assay in zebrafish embryos. We identified the zebrafish embryonic intestinal tissue as an ideal target for Rad51 immunostaining. After inducing DSB through irradiation, Rad51 foci were present in irradiated embryos but not in unirradiated controls. We present a method for accurate quantification of HR. Both morpholino-induced knockdown and knockout of Brca2 lead to almost complete absence of Rad51 foci in irradiated embryos. These findings indicate conserved function of Brca2 in zebrafish. Interestingly, a statistically significant decrease in Rad51 foci was observed in Brca2 heterozygous carriers compared to wild types, indicative of haploinsufficiency, a hypothesised cause of some tumours in patients with a germline BRCA2 mutation. In conclusion, we demonstrated the suitability of zebrafish as an excellent in vivo model system for studying the HR pathway and its functionality. PMID- 29184100 TI - AKT-mTOR signaling modulates the dynamics of IRE1 RNAse activity by regulating ER mitochondria contacts. AB - Inositol Requiring Enzyme-1 (IRE1) is the most conserved transducer of the Unfolded Protein Response (UPR), a surveillance mechanism that ensures homeostasis of the endoplasmic reticulum (ER) in eukaryotes. IRE1 activation orchestrates adaptive responses, including lipid anabolism, metabolic reprogramming, increases in protein folding competency, and ER expansion/remodeling. However, we still know surprisingly little regarding the principles by which this ER transducer is deactivated upon ER stress clearance. Here we show that Protein Kinase B-mechanistic Target of Rapamycin (PKB/AKT-mTOR) signaling controls the dynamics of IRE1 deactivation by regulating ER mitochondria physical contacts and the autophosphorylation state of IRE1. AKT mTOR-mediated attenuation of IRE1 activity is important for ER remodelling dynamics and cell survival in the face of recursive, transient ER stress. Our observations suggest that IRE1 attenuation is an integral component of anabolic programmes regulated by AKT-mTOR. We suggest that AKT-mTOR activity is part of a 'timing mechanism' to deactivate IRE1 immediately following engagement of the UPR, in order to limit prolonged IRE1 RNAse activity that could lead to damaging inflammation or apoptosis. PMID- 29184101 TI - A meta-proteomics approach to study the interspecies interactions affecting microbial biofilm development in a model community. AB - Microbial biofilms are omnipresent in nature and relevant to a broad spectrum of industries ranging from bioremediation and food production to biomedical applications. To date little is understood about how multi-species biofilm communities develop and function on a molecular level, due to the complexity of these biological systems. Here we apply a meta-proteomics approach to investigate the mechanisms influencing biofilm formation in a model consortium of four bacterial soil isolates; Stenotrophomonas rhizophila, Xanthomonas retroflexus, Microbacterium oxydans and Paenibacillus amylolyticus. Protein abundances in community and single species biofilms were compared to describe occurring inter species interactions and the resulting changes in active metabolic pathways. To obtain full taxonomic resolution between closely related species and empower correct protein quantification, we developed a novel pipeline for generating reduced reference proteomes for spectral database searches. Meta-proteomics profiling indicated that community development is dependent on cooperative interactions between community members facilitating cross-feeding on specific amino acids. Opposite regulation patterns of fermentation and nitrogen pathways in Paenibacillus amylolyticus and Xanthomonas retroflexus may, however, indicate that competition for limited resources also affects community development. Overall our results demonstrate the multitude of pathways involved in biofilm formation in mixed communities. PMID- 29184102 TI - Pressure-induced magnetic moment abnormal increase in Mn2FeAl and non-continuing decrease in Fe2MnAl via first principles. AB - The magnetism of Fe2MnAl and Mn2FeAl compounds are studied by first principles. Evolutions of magnetic moment of Fe2MnAl display distinct variation trends under pressure, showing three different slopes at different pressure intervals, 0~100 GPa, 100~250 GPa, 250-400 GPa, respectively, and the moment collapses finally at 450 GPa. The magnetic moment of Mn2FeAl shows an increasing tendency below 40 GPa and decreases subsequently with pressure, and collapses ultimately at about 175 GPa. Such non-continuing decrease of Fe2MnAl originates from the unusual charge transfer of Fe and Mn and bond populations rearrangement of Fe-Fe and Mn-Fe, whereas the distinct moment evolution of Mn2FeAl is attributed to the complicated distributions of bond populations. The half-metallicity of the compounds can be maintained at low pressure, below about 100 GPa in Fe2MnAl and 50 GPa in Mn2FeAl. The magnetic moment collapse process didn't induce volume and bond length anomalies in the two compounds, the unique anomaly is the elastic softening behaviour in elastic constant c 44 and shear (G) and Young's (E) moduli of Fe2MnAl at 270 GPa, where the second moment collapse occurs. PMID- 29184103 TI - Inconsistency in the Crown-to-Root Ratios of Single-Rooted Premolars Measured by 2D and 3D Examinations. AB - Micro-computed tomography (micro-CT) was applied to elucidate the relationship between the three-dimensional (3D) root surface area (RSA) and two-dimensional (2D) crown-to-root ratio (CRR) of extracted teeth to classify the periodontitis and assign a periodontal/prosthetic prognosis. A total of 31 maxillary and 35 mandibular single-rooted human premolars were examined. The amount of periodontal support on the basis of 3D RSA and 2D root length (RL) at CRRs of 1:1, 5:4, 3:2, and 2:1 were analyzed. Both maxillary and mandibular premolars demonstrated a nonsignificant RSA percentage at the evaluated CRRs. The coronal 21%-22% 2D RL and the 26%-28% 3D RSA bone loss apical to the cemento-enamel junction corresponded to a CRR of 1:1, relating to mild-moderate periodontitis. The coronal 30%-31% 2D RL and the 41%-42% 3D RSA bone loss corresponded to a CRR of 5:4, correlating to severe periodontitis. More severe clinical attachment loss (CAL) was observed in the 3D RSA measurement than in the 2D RL measurement at the evaluated CRRs. The amount of CAL at the CRR of 1:1 was inadequate to assess the severity of periodontitis on the basis of the 2D RL and 3D RSA measurements. PMID- 29184104 TI - Dynamic modulation of the perceptual load on microsaccades during a selective spatial attention task. AB - Selective spatial attention enhances task performance at restricted regions within the visual field. The magnitude of this effect depends on the level of attentional load, which determines the efficiency of distractor rejection. Mechanisms of attentional load include perceptual selection and/or cognitive control involving working memory. Recent studies have provided evidence that microsaccades are influenced by spatial attention. Therefore, microsaccade activities may be exploited to help understand the dynamic control of selective attention under different load levels. However, previous reports in humans on the effect of attentional load on microsaccades are inconsistent, and it is not clear to what extent these results and the dynamic changes of microsaccade activities are similar in monkeys. We trained monkeys to perform a color detection task in which the perceptual load was manipulated by task difficulty with limited involvement of working memory. Our results indicate that during the task with high perceptual load, the rate and amplitude of microsaccades immediately before the target color change were significantly suppressed. We also found that the occurrence of microsaccades before the monkeys' detection response deteriorated their performance, especially in the hard task. We propose that the activity of microsaccades might be an efficacious indicator of the perceptual load. PMID- 29184105 TI - Estimating the incubation period of hand, foot and mouth disease for children in different age groups. AB - Hand, foot and mouth disease (HFMD) is a childhood disease causing large outbreaks frequently in Asia and occasionally in Europe and the US. The incubation period of HFMD was typically described as about 3-7 days but empirical evidence is lacking. In this study, we estimated the incubation period of HFMD from school outbreaks in Hong Kong, utilizing information on symptom onset and sick absence dates of students diagnosed with HFMD. A total of 99 HFMD cases from 12 schools were selected for analysis. We fitted parametric models accounting for interval censoring. Based on the best-fitted distributions, the estimated median incubation periods were 4.4 (95% CI 3.8-5.1) days, 4.7 (95% CI 4.5-5.1) days and 5.7 (95% CI 4.6-7.0) days for children in kindergartens, primary schools and secondary schools respectively. From the fitted distribution, the estimated incubation periods can be longer than 10 days for 8.8% and 23.2% of the HFMD cases in kindergarten and secondary schools respectively. Our results show that the incubation period of HFMD for secondary schools students can be longer than the ranges commonly described. An extended period of enhanced personal hygiene practice and disinfection of the environment may be needed to control outbreaks. PMID- 29184106 TI - Burkholderia cepacia lipase immobilized on heterofunctional magnetic nanoparticles and its application in biodiesel synthesis. AB - Biodiesel production using immobilized lipase as a biocatalyst is a promising process. The performance of immobilized lipase is mainly determined by supporting materials and immobilization method. To avoid the shortcomings of adsorption and covalent bonding methods, in this study, we developed a novel heterofunctional carrier of being strengthened anion exchange and weakened covalent binding to avoid activity loss and improve operational stability of the immobilized lipase. 2,3-epoxypropyltrimethylammonium chloride with epoxy and quaternary ammonium group and glutaraldehyde were grafted onto aminated magnetic nanoparticles (AMNPs) to generate a new matrix, named GEAMNP. Then Burkholderia cepacia lipase (BCL) was immobilized on GEAMNP via anion exchange and covalent bonding. The transesterification between soybean oil and methanol was used to test the activities. Activity recovery of the immobilized BCL was up to 147.4% and the corresponding transesterification activity was 1.5-fold than that of BCL powder. The immobilized lipase was further used for biodiesel production to confirm its feasibility. The fatty acid methyl esters conversion yield could reach 96.8% in the first 12 h. Furthermore, the immobilized lipase, BCL-GEAMNP showed markedly improved operational stability, better reusability and higher esters than BCL GAMNP, where MNPs were only modified with (3-aminopropyl) triethoxysilane and glutaraldehyde. PMID- 29184107 TI - In-situ high-resolution visualization of laser-induced periodic nanostructures driven by optical feedback. AB - Optical feedback is often evoked in laser-induced periodic nanostructures. Visualizing the coupling between surfaces and light requires highly-resolved imaging methods. We propose in-situ structured-illumination-microscopy to observe ultrafast-laser-induced nanostructures during fabrication on metallic glass surfaces. This resolves the pulse-to-pulse development of periodic structures on a single irradiation site and indicates the optical feedback on surface topographies. Firstly, the quasi-constancy of the ripples pattern and the reinforcement of the surface relief with the same spatial positioning indicates a phase-locking mechanism that stabilizes and amplifies the ordered corrugation. Secondly, on sites with uncorrelated initial corrugation, we observe ripple patterns spatially in-phase. These feedback aspects rely on the electromagnetic interplay between the laser pulse and the surface relief, stabilizing the pattern in period and position. They are critically dependent on the space-time coherence of the exciting pulse. This suggests a modulation of energy according to the topography of the surface with a pattern phase imposed by the driving pulse. A scattering and interference model for ripple formation on surfaces supports the experimental observations. This relies on self-phase-stabilized far-field interaction between surface scattered wavelets and the incoming pulse front. PMID- 29184109 TI - Activation of Erk in ileal epithelial cells engaged in ischemic-injury repair. AB - Intestinal epithelial cells function as a barrier to protect our body from various agents; therefore, any damage to these cells must be immediately repaired. Several in vivo and vitro studies have shown the involvement of Erk (extracellular signal-regulated kinase) in the regeneration process; however, the spatial regulation of Erk related to tissue morphology has not been well documented. Using two-photon microscopy and mice carrying a Forster resonance energy transfer-based biosensor, we here monitored the Erk activity in the ileal epithelial cells of living mice. Forty-eight h after ischemia-induced injury, epithelial cells were observed as a monolayer covering the injured area. The Erk activity in these cells was higher than that in the epithelial cells at the surrounding crypts, and treatment with an epidermal growth factor receptor inhibitor cancelled the higher Erk activity. The resealing epithelial cells were not in the G2/M phase of the cell cycle, and Yap (Yes-associated protein) was localized to the nucleus. Immunostaining of intestinal ulcers from patients revealed ERK phosphorylation and nucleus localization of YAP without Ki-67 staining in the resealing epithelial cells. These findings led us to propose that the YAP-EGFR-ERK axis is involved in migration, but not in proliferation, of the resealing epithelial cells.

AB - A new type of proton acceleration stemming from large-scale gradients, low density targets, irradiated by an intense near-infrared laser is observed. The produced protons are characterized by high-energies (with a broad spectrum), are emitted in a very directional manner, and the process is associated to relaxed laser (no need for high-contrast) and target (no need for ultra-thin or expensive targets) constraints. As such, this process appears quite effective compared to the standard and commonly used Target Normal Sheath Acceleration technique (TNSA), or more exploratory mechanisms like Radiation Pressure Acceleration (RPA). The data are underpinned by 3D numerical simulations which suggest that in these conditions a Low Density Collisionless Shock Acceleration (LDCSA) mechanism is at play, which combines an initial Collisionless Shock Acceleration (CSA) to a boost procured by a TNSA-like sheath field in the downward density ramp of the target, leading to an overall broad spectrum. Experiments performed at a laser intensity of 1020 W/cm2 show that LDCSA can accelerate, from ~1% critical density, mm-scale targets, up to 5 * 109 protons/MeV/sr/J with energies up to 45(+/-5) MeV in a collimated (~6 degrees half-angle) manner.

AB - Among different therapeutic applications of Ultrasound (US), transient membrane sonoporation (SP) - a temporary, non-lethal porosity, mechanically induced in cell membranes through US exposure - represents a compelling opportunity towards an efficient and safe drug delivery. Nevertheless, progresses in this field have been limited by an insufficient understanding of the potential cytotoxic effects of US related to the failure of the cellular repair and to the possible activation of inflammatory pathway. In this framework we studied the in vitro effects of very low-intensity US on a human keratinocyte cell line, which represents an ideal model system of skin protective barrier cells which are the first to be involved during medical US treatments. Bioeffects linked to US application at 1 MHz varying the exposure parameters were investigated by fluorescence microscopy and fluorescence activated cell sorting. Our results indicate that keratinocytes undergoing low US doses can uptake drug model molecules with size and efficiency which depend on exposure parameters. According to sub-cavitation SP models, we have identified the range of doses triggering transient membrane SP, actually with negligible biological damage. By increasing US doses we observed a reduced cells viability and an inflammatory gene overexpression enlightening novel healthy relevant strategies.

AB - Invasive pulmonary aspergillosis results in 450,000 deaths per year and complicates cancer chemotherapy, transplantations and the treatment of other immunosuppressed patients. Using a rat model of experimental aspergillosis, the fungal siderophores ferricrocin and triacetylfusarinine C were identified as markers of aspergillosis and quantified in urine, serum and lung tissues. Biomarkers were analyzed by matrix-assisted laser desorption ionization (MALDI) and electrospray ionization mass spectrometry using a 12T SolariX Fourier transform ion cyclotron resonance (FTICR) mass spectrometer. The limits of detection of the ferri-forms of triacetylfusarinine C and ferricrocin in the rat serum were 0.28 and 0.36 ng/mL, respectively. In the rat urine the respective limits of detection achieved 0.02 and 0.03 ng/mL. In the sera of infected animals, triacetylfusarinine C was not detected but ferricrocin concentration fluctuated in the 3-32 ng/mL range. Notably, the mean concentrations of triacetylfusarinine C and ferricrocin in the rat urine were 0.37 and 0.63 MUg/mL, respectively. The MALDI FTICR mass spectrometry imaging illustrated the actual microbial ferricrocin distribution in the lung tissues and resolved the false positive results obtained by the light microscopy and histological staining. Ferricrocin and triacetylfusarinine C detection in urine represents an innovative non-invasive indication of Aspergillus infection in a host. PMID- 29184112 TI - Ecto-ADP-ribosyltransferase ARTC2.1 functionally modulates FcgammaR1 and FcgammaR2B on murine microglia. AB - Mammalian ecto-ADP-ribosyltransferases (ecto-ARTs or also ARTCs) catalyze the ADP ribosylation of cell surface proteins using extracellular nicotinamide adenine dinucleotide (NAD+) as substrate. By this post-translational protein modification, ecto-ARTs modulate the function of various target proteins. A functional role of ARTC2 has been demonstrated for peripheral immune cells such as T cells and macrophages. Yet, little is known about the role of ecto-ARTs in the central nervous system and on microglia. Here, we identified ARTC2.1 as the major ecto-ART expressed on murine microglia. ARTC2.1 expression was strongly upregulated on microglia upon co-stimulation with LPS and an ERK1/2 inhibitor or upon IFNbeta stimulation. We identified several target proteins modified by ARTC2.1 on microglia with a recently developed mass spectrometry approach, including two receptors for immunoglobulin G (IgG), FcgammaR1 and FcgammaR2B. Both proteins were verified as targets of ARTC2.1 in vitro using a radiolabeling assay with 32P-NAD+ as substrate. Moreover, ADP-ribosylation of both targets strongly inhibited their capacity to bind IgG. In concordance, ARTC2.1 induction in WT microglia and subsequent cell surface ADP-ribosylation significantly reduced the phagocytosis of IgG-coated latex beads, which was unimpaired in NAD+/DTT treated microglia from ARTC2.1-/- mice. Hence, induction of ARTC2.1 expression under inflammatory conditions, and subsequent ADP-ribosylation of cell surface target proteins could represent a hitherto unnoticed mechanism to regulate the immune response of murine microglia. PMID- 29184113 TI - A flexible plasma-treated silver-nanowire electrode for organic light-emitting devices. AB - Silver nanowires (AgNWs) are a promising candidate to replace indium tin oxide (ITO) as transparent electrode material. However, the loose contact at the junction of the AgNWs and residual surfactant polyvinylpyrrolidone (PVP) increase the sheet resistance of the AgNWs. In this paper, an argon (Ar) plasma treatment method is applied to pristine AgNWs to remove the PVP layer and enhance the contact between AgNWs. By adjusting the processing time, we obtained AgNWs with a sheet resistance of 7.2Omega/? and a transmittance of 78% at 550 nm. To reduce the surface roughness of the AgNWs, a peel-off process was used to transfer the AgNWs to a flexible NOA63 substrate. Then, an OLED was fabricated with the plasma treated AgNWs electrode as anode. The highest brightness (27000 cd/m2) and current efficiency (11.8 cd/A) was achieved with a 30 nm thick light emitting layer of tris-(8-hydroxyquinoline) aluminum doped with 1% 10-(2-benzothiazolyl) 2,3,6,7-tetrahydro-1,1,7,7-tetramethyl-1H,5 H,11H-(1)-benzopyropyrano(6,7-8 I,j)quinolizin-11-one. Compared to thermal annealing, the plasma-treated AgNW film has a lower sheet resistance, a shorter processing time, and a better hole injection. Our results indicate that plasma treatment is an effective and efficient method to enhance the conductivity of AgNW films, and the plasma treated AgNW electrode is suitable to manufacture flexible organic optoelectronic devices. PMID- 29184114 TI - Label-free nanoscale optical metrology on myelinated axons in vivo. AB - In the mammalian nervous system, myelin provides electrical insulation for the neural circuit by forming a highly organized, multilayered thin film around the axon fibers. Here, we investigate the spectral reflectance from this subcellular nanostructure and devise a new label-free technique based on a spectroscopic analysis of reflected light, enabling nanoscale imaging of myelinated axons in their natural living state. Using this technique, we demonstrate three dimensional mapping of the axon diameter and sensing of dynamic changes in the substructure of myelin at nanoscale. We further reveal the prevalence of axon bulging in the brain cortex in vivo after mild compressive trauma. Our novel tool opens new avenues of investigation by creating unprecedented access to the nanostructural dynamics of live myelinated axons in health and disease. PMID- 29184115 TI - Scene grammar shapes the way we interact with objects, strengthens memories, and speeds search. AB - Predictions of environmental rules (here referred to as "scene grammar") can come in different forms: seeing a toilet in a living room would violate semantic predictions, while finding a toilet brush next to the toothpaste would violate syntactic predictions. The existence of such predictions has usually been investigated by showing observers images containing such grammatical violations. Conversely, the generative process of creating an environment according to one's scene grammar and its effects on behavior and memory has received little attention. In a virtual reality paradigm, we either instructed participants to arrange objects according to their scene grammar or against it. Subsequently, participants' memory for the arrangements was probed using a surprise recall (Exp1), or repeated search (Exp2) task. As a result, participants' construction behavior showed strategic use of larger, static objects to anchor the location of smaller objects which are generally the goals of everyday actions. Further analysis of this scene construction data revealed possible commonalities between the rules governing word usage in language and object usage in naturalistic environments. Taken together, we revealed some of the building blocks of scene grammar necessary for efficient behavior, which differentially influence how we interact with objects and what we remember about scenes. PMID- 29184117 TI - Context-Dependent Effect of Reverberation on Material Perception from Impact Sound. AB - Our hearing is usually robust against reverberation. This study asked how such robustness to daily sound is realized, and what kinds of acoustic cues contribute to the robustness. We focused on the perception of materials based on impact sounds, which is a common daily experience, and for which the responsible acoustic features have already been identified in the absence of reverberation. In our experiment, we instructed the participants to identify materials from impact sounds with and without reverberation. The imposition of reverberation did not alter the average responses across participants to perceived materials. However, an analysis of each participant revealed the significant effect of reverberation with response patterns varying among participants. The effect depended on the context of the stimulus presentation, namely it was smaller for a constant reverberation than when the reverberation varied presentation by presentation. The context modified the relative contribution of the spectral features of the sounds to material identification, while no consistent change across participants was observed as regards the temporal features. Although the detailed results varied greatly among the participants, these results suggest that a mechanism exists in the auditory system that compensates for reverberation based on adaptation to the spectral features of reverberant sound. PMID- 29184116 TI - Proteomic and microRNA Transcriptome Analysis revealed the microRNA-SmyD1 network regulation in Skeletal Muscle Fibers performance of Chinese perch. AB - Fish myotomes are comprised of anatomically segregated fast and slow muscle fibers that possess different metabolic and contractile properties. Although the expression profile properties in fast and slow muscle fibers had been investigated at the mRNA levels, a comprehensive analysis at proteomic and microRNA transcriptomic levels is limited. In the present study, we first systematically compared the proteomic and microRNA transcriptome of the slow and fast muscles of Chinese perch (Siniperca chuatsi). Total of 2102 proteins were identified in muscle tissues. Among them, 99 proteins were differentially up regulated and 400 were down-regulated in the fast muscle compared with slow muscle. MiRNA microarrays revealed that 199 miRNAs identified in the two types of muscle fibers. Compared with the fast muscle, the 32 miRNAs was up-regulated and 27 down-regulated in the slow muscle. Specifically, expression of miR-103 and miR 144 was negatively correlated with SmyD1a and SmyD1b expression in fast and slow muscles, respectively. The luciferase reporter assay further verified that the miR-103 and miR-144 directly regulated the SmyD1a and SmyD1b expression by targeting their 3'-UTR. The constructed miRNA-SmyD1 interaction network might play an important role in controlling the development and performance of different muscle fiber types in Chinese perch. PMID- 29184118 TI - CO2 Mitigation Potential of Plug-in Hybrid Electric Vehicles larger than expected. AB - The actual contribution of plug-in hybrid and battery electric vehicles (PHEV and BEV) to greenhouse gas mitigation depends on their real-world usage. Often BEV are seen as superior as they drive only electrically and do not have any direct emissions during driving. However, empirical evidence on which vehicle electrifies more mileage with a given battery capacity is lacking. Here, we present the first systematic overview of empirical findings on actual PHEV and BEV usage for the US and Germany. Contrary to common belief, PHEV with about 60 km of real-world range currently electrify as many annual vehicles kilometres as BEV with a much smaller battery. Accordingly, PHEV recharged from renewable electricity can highly contribute to green house gas mitigation in car transport. Including the higher CO2eq emissions during the production phase of BEV compared to PHEV, PHEV show today higher CO2eq savings then BEVs compared to conventional vehicles. However, for significant CO2eq improvements of PHEV and particularly of BEVs the decarbonisation of the electricity system should go on. PMID- 29184119 TI - Rare earth element geochemistry characteristics of seawater and porewater from deep sea in western Pacific. AB - Deep-sea sediments contain high concentrations of rare earth element (REE) which have been regarded as a huge potential resource. Understanding the marine REE cycle is important to reveal the mechanism of REE enrichment. In order to determine the geochemistry characteristics and migration processes of REE, seawater, porewater and sediment samples were systematically collected from the western Pacific for REE analysis. The results show a relatively flat REE pattern and the HREE (Heavy REE) enrichment in surface and deep seawater respectively. The HREE enrichment distribution patterns, low concentrations of Mn and Fe and negative Ce anomaly occur in the porewater, and high Mn/Al ratios and low U concentrations were observed in sediment, indicating oxic condition. LREE (Light REE) and MREE (Middle REE) enrichment in upper layer and depletion of MREE in deeper layer were shown in porewater profile. This study suggests that porewater flux in the western Pacific basin is a minor source of REEs to seawater, and abundant REEs are enriched in sediments, which is mainly caused by the extensive oxic condition, low sedimentation rate and strong adsorption capacity of sediments. Hence, the removal of REEs of porewater may result in widespread REE rich sediments in the western Pacific basin. PMID- 29184120 TI - Halistanol sulfates I and J, new SIRT1-3 inhibitory steroid sulfates from a marine sponge of the genus Halichondria. AB - Two new analogs of halistanol sulfate (1) were isolated from a marine sponge Halichondria sp. collected at Hachijo-jima Island. Structures of these new halistanol sulfates I (2) and J (3) were elucidated by spectral analyses. Compounds 1-3 showed inhibitory activity against SIRT 1-3 with IC50 ranges of 45.9-67.9, 18.9-21.1 and 21.8-37.5 MUM, respectively. X-ray crystallography of the halistanol sulfate (1) and SIRT3 complex clearly indicates that 1 binds to the exosite of SIRT3 that we have discovered in this study. PMID- 29184121 TI - Isolation and structure elucidation of lipopeptide antibiotic taromycin B from the activated taromycin biosynthetic gene cluster. AB - In the ongoing effort to unlock the chemical potential of marine bacteria, genetic engineering of biosynthetic gene clusters (BGCs) is increasingly used to awake or improve expression of biosynthetic genes that may lead to discovery of novel bioactive natural products. Previously, we reported the successful capture, engineering and heterologous expression of an orphan BGC from the marine actinomycete Saccharomonospora sp. CNQ-490, which resulted in the isolation of the novel lipopeptide antibiotic taromycin A. Herein we report the isolation and structure elucidation of taromycin B, the second most abundant product of the taromycin biosynthetic series, and show that taromycins A and B exhibit complex chromatographic properties indicative of interconverting conformations. Taromycins A and B display potent activity against methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecium clinical isolates, suggestive that the taromycin molecular scaffold is a promising starting point for further derivatization to produce compounds with promising antibiotic characteristics. PMID- 29184122 TI - Bacterial alterations in salivary microbiota and their association in oral cancer. AB - Oral squamous cell carcinoma (OSCC) is the most common malignant neoplasm of the oral cavity and the fourth leading malignancy and cause of cancer-related death in the male population of Taiwan. Most cases are detected at advanced stages, resulting in poor prognosis. Therefore, improved detection of early oral health disorders is indispensable. The involvement of oral bacteria in inflammation and their association with OSCC progression provide a feasible target for diagnosis. Due to the nature of oral neoplasms, the diagnosis of epithelial precursor lesions is relatively easy compared with that of other types of cancer. However, the transition from an epithelial precursor lesion to cancer is slow and requires further and continuous follow-up. In this study, we investigated microbiota differences between normal individuals, epithelial precursor lesion patients, and cancer patients with different lifestyle habits, such as betel chewing and smoking, using next-generation sequencing. Overall, the oral microbiome compositions of five genera, Bacillus, Enterococcus, Parvimonas, Peptostreptococcus, and Slackia, revealed significant differences between epithelial precursor lesion and cancer patients and correlated with their classification into two clusters. These composition changes might have the potential to constitute a biomarker to help in monitoring the oral carcinogenesis transition from epithelial precursor lesion to cancer. PMID- 29184123 TI - Dynamic domain arrangement of CheA-CheY complex regulates bacterial thermotaxis, as revealed by NMR. AB - Bacteria utilize thermotaxis signal transduction proteins, including CheA, and CheY, to switch the direction of the cell movement. However, the thermally responsive machinery enabling warm-seeking behavior has not been identified. Here we examined the effects of temperature on the structure and dynamics of the full length CheA and CheY complex, by NMR. Our studies revealed that the CheA-CheY complex exists in equilibrium between multiple states, including one state that is preferable for the autophosphorylation of CheA, and another state that is preferable for the phosphotransfer from CheA to CheY. With increasing temperature, the equilibrium shifts toward the latter state. The temperature dependent population shift of the dynamic domain arrangement of the CheA-CheY complex induced changes in the concentrations of phosphorylated CheY that are comparable to those induced by chemical attractants or repellents. Therefore, the dynamic domain arrangement of the CheA-CheY complex functions as the primary thermally responsive machinery in warm-seeking behavior. PMID- 29184124 TI - Percolation channels: a universal idea to describe the atomic structure and dynamics of glasses and melts. AB - Understanding the links between chemical composition, nano-structure and the dynamic properties of silicate melts and glasses is fundamental to both Earth and Materials Sciences. Central to this is whether the distribution of mobile metallic ions is random or not. In silicate systems, such as window glass, it is well-established that the short-range structure is not random but metal ions cluster, forming percolation channels through a partly broken network of corner sharing SiO4 tetrahedra. In alumino-silicate glasses and melts, extensively used in industry and representing most of the Earth magmas, metal ions compensate the electrical charge deficit of AlO4- tetrahedra, but until now clustering has not been confirmed. Here we report how major changes in melt viscosity, together with glass Raman and Nuclear Magnetic Resonance measurements and Molecular Dynamics simulations, demonstrate that metal ions nano-segregate into percolation channels, making this a universal phenomenon of oxide glasses and melts. Furthermore, we can explain how, in both single and mixed alkali compositions, metal ion clustering and percolation radically affect melt mobility, central to understanding industrial and geological processes. PMID- 29184125 TI - Stiffness-dependent motility and proliferation uncoupled by deletion of CD44. AB - Information in the microenvironment guides complex cellular decisions such as whether or not to proliferate and migrate. The effects of soluble extracellular signals on these cellular functions are fairly well understood, but relatively little is known about how the extracellular matrix (ECM), and particularly the mechanical information in the ECM, guides these cellular decisions. Here, we show that CD44, a major receptor for the glycosaminoglycan ECM component hyaluronan, coordinates the motility and proliferative responses to ECM stiffening. We analyzed these cellular responses on fibronectin-coated polyacrylamide hydrogels prepared at a physiologic range of ECM stiffness and found that stiffening of the ECM leads to both cell cycling and cell motility in serum-stimulated primary mouse dermal fibroblasts. Remarkably, deletion of CD44 impaired stiffness stimulated motility of the primary cells without affecting other hallmark cellular responses to ECM stiffening including cell spread area, stress fiber formation, focal adhesion maturation, and intracellular stiffening. Even stiffness-mediated cell proliferation was unaffected by deletion of CD44. Our results reveal a novel effect of CD44, which is imposed downstream of ECM mechanosensing and determines if cells couple or uncouple their proliferative and motility responses to ECM stiffness. PMID- 29184128 TI - Circularly-polarized, semitransparent and double-sided holograms based on helical photonic structures. AB - Recent advances in nanofabrication techniques are opening new frontiers in holographic devices, with the capability to integrate various optical functions in a single device. However, while most efficient holograms are achieved in reflection-mode configurations, they are in general opaque because of the reflective substrate that must be used, and therefore, have limited applicability. Here, we present a semi-transparent, reflective computer-generated hologram that is circularly-polarization dependent, and reconstructs different wavefronts when viewed from different sides. The integrated functionality is realized using a single thin-film of liquid crystal with a self-organized helical structure that Bragg reflects circularly-polarized light over a certain band of wavelengths. Asymmetry depending on the viewing side is achieved by exploiting the limited penetration depth of light in the helical structure as well as the nature of liquid crystals to conform to different orientational patterns imprinted on the two substrates sandwiching the material. Also, because the operation wavelength is determined by the reflection band position, pseudo-color holograms can be made by simply stacking layers with different designs. The unique characteristics of this hologram may find applications in polarization encoded security holograms and see-through holographic signage where different information need to be displayed depending on the viewing direction. PMID- 29184127 TI - Deficiency of a brain-specific chemokine-like molecule, SAM3, induces cardinal phenotypes of autism spectrum disorders in mice. AB - Chemokines are small secreted signaling proteins produced by a broad range of cells, including immune cells. Several studies have recently suggested potential roles of chemokines and their receptors in the pathophysiology of autism spectrum disorders (ASDs). SAM3 is a novel brain-specific chemokine-like molecule with an unknown physiological function. We explored the relevance of chemokines in the development of ASD in mice, with a focus on SAM3. We generated Sam3 gene knockout (KO) mice and characterized their behavioral phenotypes, with a focus on those relevant to ASD. Sam3-deficient mice displayed all three core phenotypes of ASD: impaired responses to social novelty, defects in social communication, and increased repetitive behavior. In addition, they showed increased anxiety. Interestingly, gender differences were identified for several behaviors: only male Sam3 KO mice exhibited increased anxiety and increased repetitive behaviors. Sam3 KO mice did not exhibit changes in other behaviors, including locomotor activities, fear learning and memory, and object recognition memory. These findings indicate that a deficiency of SAM3, a novel brain-specific chemokine like molecule, may lead to the pathogenesis of ASDs and suggest the possibility that SAM3, a soluble factor, could be a novel therapeutic target for ASD treatment. PMID- 29184126 TI - Genetic and pharmacological inhibition of microRNA-92a maintains podocyte cell cycle quiescence and limits crescentic glomerulonephritis. AB - Crescentic rapidly progressive glomerulonephritis (RPGN) represents the most aggressive form of acquired glomerular disease. While most therapeutic approaches involve potentially toxic immunosuppressive strategies, the pathophysiology remains incompletely understood. Podocytes are glomerular epithelial cells that are normally growth-arrested because of the expression of cyclin-dependent kinase (CDK) inhibitors. An exception is in RPGN where podocytes undergo a deregulation of their differentiated phenotype and proliferate. Here we demonstrate that microRNA-92a (miR-92a) is enriched in podocytes of patients and mice with RPGN. The CDK inhibitor p57Kip2 is a major target of miR-92a that constitutively safeguards podocyte cell cycle quiescence. Podocyte-specific deletion of miR-92a in mice de-repressed the expression of p57Kip2 and prevented glomerular injury in RPGN. Administration of an anti-miR-92a after disease initiation prevented albuminuria and kidney failure, indicating miR-92a inhibition as a potential therapeutic strategy for RPGN. We demonstrate that miRNA induction in epithelial cells can break glomerular tolerance to immune injury. PMID- 29184129 TI - Fracture toughness and structural evolution in the TiAlN system upon annealing. AB - Hard coatings used to protect engineering components from external loads and harsh environments should ideally be strong and tough. Here we study the fracture toughness, K IC, of Ti1-xAlxN upon annealing by employing micro-fracture experiments on freestanding films. We found that K IC increases by about 11% when annealing the samples at 900 degrees C, because the decomposition of the supersaturated matrix leads to the formation of nanometer-sized domains, precipitation of hexagonal-structured B4 AlN (with their significantly larger specific volume), formation of stacking faults, and nano-twins. In contrast, for TiN, where no decomposition processes and formation of nanometer-sized domains can be initiated by an annealing treatment, the fracture toughness K IC remains roughly constant when annealed above the film deposition temperature. As the increase in K IC found for Ti1-xAlxN upon annealing is within statistical errors, we carried out complementary cube corner nanoindentation experiments, which clearly show reduced (or even impeded) crack formation for annealed Ti1-xAlxN as compared with their as-deposited counterpart. The ability of Ti1-xAlxN to maintain and even increase the fracture toughness up to high temperatures in combination with the concomitant age hardening effects and excellent oxidation resistance contributes to the success of this type of coatings. PMID- 29184130 TI - In-vivo longitudinal imaging of microvascular changes in irradiated oral mucosa of radiotherapy cancer patients using optical coherence tomography. AB - Mucositis is the limiting toxicity of radio(chemo)therapy of head and neck cancer. Diagnostics, prophylaxis and correction of this condition demand new accurate and objective approaches. Here we report on an in vivo longitudinal monitoring of the oral mucosa dynamics in 25 patients during the course of radiotherapy of oropharyngeal and nasopharyngeal cancer using multifunctional optical coherence tomography (OCT). A spectral domain OCT system with a specially designed oral imaging probe was used. Microvasculature visualization was based on temporal speckle variations of the full complex signal evaluated by high-pass filtering of 3D data along the slow scan axis. Angiographic image quantification demonstrated an increase of the vascular density and total length of capillary like-vessels before visual signs or clinical symptoms of mucositis occur. Especially significant microvascular changes compared to their initial levels occurred when grade two and three mucositis developed. Further, microvascular reaction was seen to be dose-level dependent. OCT monitoring in radiotherapy offers a non-invasive, convenient, label-free quantifiable structural and functional volumetric imaging method suitable for longitudinal human patient studies, furnishing fundamental radiobiological insights and potentially providing useful feedback data to enable adaptive radiotherapy (ART). PMID- 29184131 TI - Anti-cancer capacity of plasma-treated PBS: effect of chemical composition on cancer cell cytotoxicity. AB - We evaluate the anti-cancer capacity of plasma-treated PBS (pPBS), by measuring the concentrations of NO2- and H2O2 in pPBS, treated with a plasma jet, for different values of gas flow rate, gap and plasma treatment time, as well as the effect of pPBS on cancer cell cytotoxicity, for three different glioblastoma cancer cell lines, at exactly the same plasma treatment conditions. Our experiments reveal that pPBS is cytotoxic for all conditions investigated. A small variation in gap between plasma jet and liquid surface (10 mm vs 15 mm) significantly affects the chemical composition of pPBS and its anti-cancer capacity, attributed to the occurrence of discharges onto the liquid. By correlating the effect of gap, gas flow rate and plasma treatment time on the chemical composition and anti-cancer capacity of pPBS, we may conclude that H2O2 is a more important species for the anti-cancer capacity of pPBS than NO2-. We also used a 0D model, developed for plasma-liquid interactions, to elucidate the most important mechanisms for the generation of H2O2 and NO2-. Finally, we found that pPBS might be more suitable for practical applications in a clinical setting than (commonly used) plasma-activated media (PAM), because of its higher stability. PMID- 29184132 TI - Circulating complement component 4d (C4d) correlates with tumor volume, chemotherapeutic response and survival in patients with malignant pleural mesothelioma. AB - Only limited information is available on the role of complement activation in malignant pleural mesothelioma (MPM). Thus, we investigated the circulating and tissue levels of the complement component 4d (C4d) in MPM. Plasma samples from 55 MPM patients, 21 healthy volunteers (HV) and 14 patients with non-malignant pleural diseases (NMPD) were measured by ELISA for C4d levels. Tissue specimens from 32 patients were analyzed by C4d immunohistochemistry. Tumor volumetry was measured in 20 patients. We found no C4d labeling on tumor cells, but on ectopic lymphoid structures within the tumor stroma. Plasma C4d levels did not significantly differ between MPM, HV or NMPD. Late-stage MPM patients had higher plasma C4d levels compared to early-stage (p = 0.079). High circulating C4d was associated with a higher tumor volume (p = 0.047). Plasma C4d levels following induction chemotherapy were significantly higher in patients with stable/progressive disease compared to those with partial/major response (p = 0.005). Strikingly, patients with low C4d levels at diagnosis had a significantly better overall survival, confirmed in a multivariate cox regression model (hazard ratio 0.263, p = 0.01). Our findings suggest that circulating plasma C4d is a promising new prognostic biomarker in patients with MPM and, moreover, helps to select patients for surgery following induction chemotherapy. PMID- 29184133 TI - The Neurogenic Bladder Symptom Score (NBSS): a secondary assessment of its validity, reliability among people with a spinal cord injury. AB - STUDY DESIGN: Prospective cross-sectional study. OBJECTIVES: Validate the Neurogenic Bladder Symptom Score (NBSS) for people with spinal cord injury (SCI). SETTING: United States (recruitment from community/tertiary neurourology clinics). METHODS: We used data from a prospective observational study of people with a SCI who enrolled during December 2015-September 2016. Participants completed the NBSS and other measurement tools (SF-12 and SCI-QOL Bladder Management Complications tool). Data were used to determine the internal consistency (Cronbach's alpha), validity (hypothesis testing), and test-re-test reliability (using an intraclass correlation coefficient). RESULTS: 609 people with a SCI had complete data. The median NBSS total score was 22 (IQR 15-30), and median quality of life was "mixed". The Cronbach's alpha of the total and the incontinence, storage/voiding, and consequences domains was 0.85, 0.93, 0.76, and 0.49 respectively. All item to domain correlations were >=0.3, aside from 3/7 of the items from the consequences domain. Appropriate correlations between the NBSS domains and external variables and other questionnaires were observed, such as a moderate correlation between the SCI-QOL Bladder Management complications tool and the NBSS total score. For the reliability assessment, 174 people had 3 month followup data and did not have a significant change to their urologic health. The intraclass correlation coefficients were >0.75 for all subdomains and the overall score. CONCLUSIONS: The NBSS demonstrated good validity and reliability in a large cohort of people with a SCI, and is a suitable tool to assess neurogenic bladder symptoms.

PMID- 29184135 TI - Impact of visceral fat on surgical complications and long-term survival of patients with gastric cancer after radical gastrectomy. AB - BACKGROUND/OBJECTIVES: The aim of this study was to examine the impact of visceral fat on surgical complications and long-term survival for patients undergoing radical gastrectomy. SUBJECTS/METHODS: From 2009 to 2013, 859 patients who underwent curative resection for gastric cancer were enrolled from a prospectively maintained database. Visceral fat area (VFA) was assessed by preoperative CT scans. Patients were divided into two groups by VFA. Perioperative variables and postoperative outcomes were compared between the high VFA group and low VFA group. Univariable and multivariable analysis were performed to investigate independent risk factors of postoperative complications and survival. RESULTS: Some 859 patients were included in the study, 308 of whom were classified as high VFA. High VFA was correlated with advance age (P = 0.020), higher albumin levels (P = 0.001), hemoglobin levels (P < 0.05), ASA grade (P = 0.043) and Charlson Comorbidity Index (P = 0.004). Relative to patients with low VFA, those with high VFA had longer surgical durations (P = 0.004), higher rate of postoperative complications (P = 0.004), and longer hospital stays (P = 0.004). High VFA was identified as the only determinant for surgical complications by logistic regression analysis (OR, 2.236, 95% CI, 1.537 3.254; P < 0.001). Cox proportional hazards regression revealed no correlation between VFA and overall survival (OS) or disease-free survival (DFS). CONCLUSIONS: Increased VFA independently predicts surgical complications in patients after gastrectomy. However, VFA is not a prognostic biomarker of OS or DFS in patients with gastric cancer.

AB - Poxviruses are large DNA viruses with varying zoonotic potential, and are recognised in a broad range of wildlife. Although poxviruses have been detected in kangaroos, their genetic relationships to poxviruses in other animals and humans is not well understood. Here, we present a novel genome sequence of a marsupial poxvirus, the Eastern grey kangaroopox virus (EKPV-NSW), isolated from a wild eastern grey kangaroo. In the present study, histopathologically confirmed epidermal pox lesions were used to recover the full-length viral genome and perform electron microscopic analysis, with both immature virions and intracellular mature virions detected. Subsequent analysis of the EKPV-NSW genome demonstrated the highest degree of sequence similarity with EKPV-SC strain (91.51%), followed by WKPV-WA (87.93%), and MOCV1 (44.05%). The novel EKPV-NSW complete genome encompasses most of the chordopoxviruses protein coding genes (138) that are required for genome replication and expression, with only three essential protein coding genes being absent. The novel EKPV-NSW is missing 28 predicted genes compared to the recently isolated EKPV-SC, and carries 21 additional unique genes, encoding unknown proteins. Phylogenetic and recombination analyses showed EKPV-NSW to be the distinct available candidate genome of chordopoxviruses.

AB - Shape control of noble metal (NM) nanocrystals (NCs) is of great importance for improving their electrocatalytic performance. In this report, branched Pd@Rh core@shell NCs that have right square prism-like arms with preferential exposure of Rh {100} facets (denoted as b-Pd@Rh-NCs thereafter) are synthesized and utilized as an electrocatalyst for the hydrazine electrooxidation (HEO) in acidic and alkaline electrolytes. The b-Pd@Rh-NCs are obtained by the heteroepitaxial growth of Rh on the pre-formed branched Pd NCs (denoted as b-Pd-NCs thereafter) core in the presence of poly(vinyl pyrrolidone) (PVP) and bromide ions. A comparative analysis of the voltammetric data for the HEO shows a higher activity on the b-Pd@Rh-NCs exposed with Rh {100} faces than on Rh black, the b-Pd-NCs, and Pd black in acid and alkaline solutions, indicating a structure sensitivity of the reaction. Analysis of the products from the b-Pd@Rh-NCs catalysed HEO reveals a very high hydrazine fuel efficiency, as determined by on-line differential electrochemical mass spectrometry (DEMS).

AB - Ash emitted during explosive volcanic eruptions may disperse over vast areas of the globe posing a threat to human health and infrastructures and causing significant disruption to air traffic. In Antarctica, at least five volcanoes have reported historic activity. However, no attention has been paid to the potential socio-economic and environmental consequences of an ash-forming eruption occurring at high southern latitudes. This work shows how ash from Antarctic volcanoes may pose a higher threat than previously believed. As a case study, we evaluate the potential impacts of ash for a given eruption scenario from Deception Island, one of the most active volcanoes in Antarctica. Numerical simulations using the novel MMB-MONARCH-ASH model demonstrate that volcanic ash emitted from Antarctic volcanoes could potentially encircle the globe, leading to significant consequences for global aviation safety. Results obtained recall the need for performing proper hazard assessment on Antarctic volcanoes, and are crucial for understanding the patterns of ash distribution at high southern latitudes with strong implications for tephrostratigraphy, which is pivotal to synchronize palaeoclimatic records. PMID- 29184138 TI - Centromere evolution and CpG methylation during vertebrate speciation. AB - Centromeres and large-scale structural variants evolve and contribute to genome diversity during vertebrate speciation. Here, we perform de novo long-read genome assembly of three inbred medaka strains that are derived from geographically isolated subpopulations and undergo speciation. Using single-molecule real-time (SMRT) sequencing, we obtain three chromosome-mapped genomes of length ~734, ~678, and ~744Mbp with a resource of twenty-two centromeric regions of length 20 345kbp. Centromeres are positionally conserved among the three strains and even between four pairs of chromosomes that were duplicated by the teleost-specific whole-genome duplication 320-350 million years ago. The centromeres do not all evolve at a similar pace; rather, centromeric monomers in non-acrocentric chromosomes evolve significantly faster than those in acrocentric chromosomes. Using methylation sensitive SMRT reads, we uncover centromeres are mostly hypermethylated but have hypomethylated sub-regions that acquire unique sequence compositions independently. These findings reveal the potential of non acrocentric centromere evolution to contribute to speciation. PMID- 29184139 TI - Hourglass Dirac chain metal in rhenium dioxide. AB - Nonsymmorphic symmetries, which involve fractional lattice translations, can generate exotic types of fermionic excitations in crystalline materials. Here we propose a topological phase arising from nonsymmorphic symmetries-the hourglass Dirac chain metal, and predict its realization in the rhenium dioxide. We show that ReO2 features hourglass-type dispersion in the bulk electronic structure dictated by its nonsymmorphic space group. Due to time reversal and inversion symmetries, each band has an additional two-fold degeneracy, making the neck crossing-point of the hourglass four-fold degenerate. Remarkably, close to the Fermi level, the neck crossing-point traces out a Dirac chain-a chain of connected four-fold-degenerate Dirac loops-in the momentum space. The symmetry protection, the transformation under symmetry-breaking, and the associated topological surface states of the Dirac chain are revealed. Our results open the door to an unknown class of topological matters, and provide a platform to explore their intriguing physics. PMID- 29184141 TI - Development and growth of organs in living whole embryo and larval grafts in zebrafish. AB - Age-related systemic environments influence neurogenesis and organ regeneration of heterochronic parabiotic partners; however, the difficulty of manipulating small embryos prevents the effects of aged systemic environments on primitive organs at the developmental stage from being analysed. Here, we describe a novel transplantation system to support whole living embryos/larvae as grafts in immunodeficient zebrafish by the intrusion of host blood vessels into the grafts, allowing bodies similar to those of heterochronic parabiosis to be generated by subcutaneous grafting. Although grafted embryos/larvae formed most organs, not all organogenesis was supported equally; although the brain, eyes and the intestine usually developed, the liver, testes and heart developed insufficiently or even occasionally disappeared. Removal of host germ cells stimulated testis development in grafted embryos. These results indicate that primitive testes are susceptible to the systemic environments that originated from the germ cells of aged hosts and imply that the primitive liver and heart are similar. Upon applying this method to embryonic lethal mutants, various types of organs, including testes that developed in germ-cell-removed recipients, and viable offspring were obtained from the mutants. This unique transplantation system will lead to new insights into the age-related systemic environments that are crucial for organogenesis in vertebrates. PMID- 29184140 TI - Induced cortical tension restores functional junctions in adhesion-defective carcinoma cells. AB - Normal epithelial cells are stably connected to each other via the apical junctional complex (AJC). AJCs, however, tend to be disrupted during tumor progression, and this process is implicated in cancer dissemination. Here, using colon carcinoma cells that fail to form AJCs, we investigated molecular defects behind this failure through a search for chemical compounds that could restore AJCs, and found that microtubule-polymerization inhibitors (MTIs) were effective. MTIs activated GEF-H1/RhoA signaling, causing actomyosin contraction at the apical cortex. This contraction transmitted force to the cadherin-catenin complex, resulting in a mechanosensitive recruitment of vinculin to cell junctions. This process, in turn, recruited PDZ-RhoGEF to the junctions, leading to the RhoA/ROCK/LIM kinase/cofilin-dependent stabilization of the junctions. RhoGAP depletion mimicked these MTI-mediated processes. Cells that normally organize AJCs did not show such MTI/RhoA sensitivity. Thus, advanced carcinoma cells require elevated RhoA activity for establishing robust junctions, which triggers tension-sensitive reorganization of actin/adhesion regulators.

PMID- 29184142 TI - A simulation model of neuroprogenitor proliferation dynamics predicts age-related loss of hippocampal neurogenesis but not astrogenesis. AB - Adult hippocampal neuroprogenitors give rise to both neurons and astrocytes. As neuroprogenitors are lost with increased age, neurogenesis concomitantly decreases. However, the dynamics of neuron and astrocyte generation throughout adulthood has not been systematically examined. Here, we analyzed the hippocampal niche both longitudinally (from 2 h to 30d of cell life) and transversally (from 1 m to 12 m of age) and generated a Marsaglia polar random simulation model to predict newborn cell dynamics. The sharp decrease in newborn neuron production throughout adulthood was largely predicted by the number of proliferating neuroprogenitors at each age. In contrast, newborn astrocyte decay was slower and associated with their increased yield in mature mice. As a result, the niche shifted from neurogenic to neuro/astrogenic with increased age. Our data provide a simple "end-point" model to understand the hippocampal niche changes across adulthood and suggest yet unexplored functions of newborn astrocytes for the aging hippocampal circuitry. PMID- 29184144 TI - Sex differences in peripheral not central immune responses to pain-inducing injury. AB - Women suffer chronic pain more frequently than men. It is not clear whether this is due to differences in higher level cognitive processes or basic nociceptive responses. In this study we used a mouse model of neuropathic pain to dissociate these factors. We performed RNA-seq on purified peripheral afferent neurons, but found no striking differences in gene expression between male and female mice, neither before nor after nerve injury. Similarly, spinal cord immune responses between the sexes appeared to be indistinguishable when studied by flow cytometry or qRT-PCR. Differences emerged only upon studying peripheral immune cell infiltration into the dorsal root ganglion, suggesting that adaptive immune responses in neuropathic pain could be sexually dimorphic.

PMID- 29184146 TI - 2,3,4',5-tetrahydroxystilbene-2-O-beta-D-glucoside exacerbates acetaminophen induced hepatotoxicity by inducing hepatic expression of CYP2E1, CYP3A4 and CYP1A2. AB - Hepatotoxicity induced by medicinal herb Polygonum multiflorum Thunb. attracts wide attention in the world recently. 2,3,4',5-tetrahydroxystilbene-2-O-beta-D glucoside (TSG) is a main active compound in Polygonum multiflorum Thunb. This study aims to observe TSG-provided the aggravation on acetaminophen (APAP) induced hepatotoxicity in mice by inducing hepatic expression of cytochrome P450 (CYP450) enzymes. Serum alanine/aspartate aminotransferase (ALT/AST) analysis and liver histological evaluation showed that TSG (200, 400, 800 mg/kg) exacerbated the hepatotoxicity induced by sub-toxic dose of APAP (200 mg/kg) in mice, but TSG alone had no hepatotoxicity. TSG aggravated hepatic reduced glutathione (GSH) depletion and APAP-cysteine adducts (APAP-CYS) formation induced by APAP in mice. TSG increased the expression of CYP2E1, CYP3A4 and CYP1A2 both in mice and in human normal liver L-02 hepatocytes. TSG also enhanced liver catalytic activity of CYP2E1, CYP3A4 and CYP1A2 in mice. TSG induced the nuclear translocation of aryl hydrocarbon receptor (AHR) and pregnane X receptor (PXR), and TSG-provided the aggravation on APAP-induced hepatotoxicity in mice was reversed by PXR or AHR inhibitors. In summary, our results demonstrate that TSG enhances hepatic expression of CYP3A4, CYP2E1 and CYP1A2, and thus exacerbates the hepatotoxicity induced by APAP in mice. PXR and AHR both play some important roles in this process. PMID- 29184147 TI - The origin of prostate gland-secreted IgA and IgG. AB - The prostate secretes immunoglobulin (Ig) A (IgA) and IgG; however, how immunoglobulins reach the secretion, where the plasma cells are located, whether immunoglobulins are antigen-specific and where activation of the adaptive response occurs are still unknown. Immune cells, including CD45RA+ cells, were scattered in the stroma and not organized mucosae-associated lymphoid-tissue. IgA (but not IgG) immunostaining identified stromal plasma cells and epithelial cells in non-immunized rats. Injected tetramethylrhodamine-IgA transcytosed the epithelium along with polymeric immunoglobulin receptor. Oral immunization with ovalbumin/mesopourous SBA-15 silica adjuvant resulted in more stromal CD45RA+/IgA+ cells, increased content of ovalbumin-specific IgA and IgG, and the appearance of intraepithelial CD45RA+/IgG+ cells. An increased number of dendritic cells that cooperate in other sites with transient immunocompetent lymphocytes, and the higher levels of interleukin-1beta, interferon-gamma and transforming growth factor-beta, explain the levels of specific antibodies. Nasal immunization produced similar results except for the increase in dendritic cells. This immunomodulatory strategy seems useful to boost immunity against genitourinary infections and, perhaps, cancer. PMID- 29184148 TI - Evaluation of radionuclides and decay simulation in a terrestrial environment for health risk assessment. AB - This study is to assess the natural radioactivity level in soil samples in communities bordering the Tano Basin in Ghana. The radioactivity concentration of 238U, 232Th and 40K have been determined using gamma-ray spectrometry, moreover, the absorbed dose rates and annual effective dose were calculated. MATLAB R2013 script was written to simulate the decay of the radionuclides 238U, 232Th and 40K using their respective half-lives. This is to determine the future impact of natural radionuclides and estimate future anthropogenic inputs. The level 238U, 232Th, and 40K ranged from (1.60 to 21.3), (2.78 to 32.2) and (111 to 528) with average values of be 8.65 Bqkg-1, 12.5 Bqkg-1 and 214 Bqkg-1 respectively in soil. The activity concentrations were lower than United Nations Scientific Committee on the Effects of Atomic Radiation guidelines for 238U, 232Th and 40K. The absorbed dose rates and annual effective dose were found to be in range of 7.79 to 37.8 nGy h-1 and 9.56E + 00 to 4.64E + 01 uSvy-1 respectively. The overall annual effective dose was lower than the allowable limit of 1mSvy-1 set by International Commission on Radiological Protection. Hex, Hin and excess lifetime cancer risk (ELCR) were calculated and found to be within internationally recommended values.

AB - Applications for high resolution 3D profiles, so-called grayscale lithography, exist in diverse fields such as optics, nanofluidics and tribology. All of them require the fabrication of patterns with reliable absolute patterning depth independent of the substrate location and target materials. Here we present a complete patterning and pattern-transfer solution based on thermal scanning probe lithography (t-SPL) and dry etching. We demonstrate the fabrication of 3D profiles in silicon and silicon oxide with nanometer scale accuracy of absolute depth levels. An accuracy of less than 1nm standard deviation in t-SPL is achieved by providing an accurate physical model of the writing process to a model-based implementation of a closed-loop lithography process. For transfering the pattern to a target substrate we optimized the etch process and demonstrate linear amplification of grayscale patterns into silicon and silicon oxide with amplification ratios of ~6 and ~1, respectively. The performance of the entire process is demonstrated by manufacturing photonic molecules of desired interaction strength. Excellent agreement of fabricated and simulated structures has been achieved. PMID- 29184151 TI - Association between antibodies against group B Streptococcus surface proteins and recto-vaginal colonisation during pregnancy. AB - Group B Streptococcus (GBS) recto-vaginal colonisation in pregnant women is the major risk factor for early-onset invasive GBS disease in their newborns. We aimed to determine the association between serum antibody levels against 11 GBS surface proteins and recto-vaginal acquisition of GBS colonisation during pregnancy. Sera collected from pregnant women at 20-25 weeks and >=37 weeks of gestation age were measured for IgG titres against GBS surface proteins using a multiplex immunoassay. Women were evaluated for recto-vaginal colonisation every 4-5 weeks. We observed that the likelihood of becoming colonised with GBS during pregnancy was lower in women with IgG titres >=200 U/mL against gbs0233 (adjusted OR = 0.47 [95% CI: 0.25-0.89], p = 0.021) and >=85 U/mL for gbs1539 (adjusted OR = 0.44 [95% CI: 0.24-0.82], p = 0.01) when comparing between women who acquired GBS colonisation and those that remained free of GBS colonisation throughout pregnancy. IgG titres (U/mL) specific to BibA and Sip were higher in pregnant women colonised with GBS (380.19 and 223.87, respectively) compared to women with negative GBS cultures (234.42 and 186.21, respectively; p < 0.01) at >=37 weeks gestation. Antibodies induced by gbs0233 and gbs1539 were associated with a reduced likelihood of recto-vaginal GBS acquisition during pregnancy and warrant further investigation as vaccine targets. PMID- 29184152 TI - Pressure driven spin transition in siderite and magnesiosiderite single crystals. AB - Iron-bearing carbonates are candidate phases for carbon storage in the deep Earth and may play an important role for the Earth's carbon cycle. To elucidate the properties of carbonates at conditions of the deep Earth, we investigated the pressure driven magnetic high spin to low spin transition of synthetic siderite FeCO3 and magnesiosiderite (Mg0.74Fe0.26)CO3 single crystals for pressures up to 57 GPa using diamond anvil cells and x-ray Raman scattering spectroscopy to directly probe the iron 3d electron configuration. An extremely sharp transition for siderite single crystal occurs at a notably low pressure of 40.4 +/- 0.1 GPa with a transition width of 0.7 GPa when using the very soft pressure medium helium. In contrast, we observe a broadening of the transition width to 4.4 GPa for siderite with a surprising additional shift of the transition pressure to 44.3 +/- 0.4 GPa when argon is used as pressure medium. The difference is assigned to larger pressure gradients in case of argon. For magnesiosiderite loaded with argon, the transition occurs at 44.8 +/- 0.8 GPa showing similar width as siderite. Hence, no compositional effect on the spin transition pressure is observed. The spectra measured within the spin crossover regime indicate coexistence of regions of pure high- and low-spin configuration within the single crystal.

PMID- 29184154 TI - A leptospiral AAA+ chaperone-Ntn peptidase complex, HslUV, contributes to the intracellular survival of Leptospira interrogans in hosts and the transmission of leptospirosis. AB - Leptospirosis caused by Leptospira is a zoonotic disease of global importance but it is considered as an emerging or re-emerging infectious disease in many areas in the world. Until now, the mechanisms about pathogenesis and transmission of Leptospira remains poorly understood. As eukaryotic and prokaryotic proteins can be denatured in adverse environments and chaperone-protease/peptidase complexes degrade these harmful proteins, we speculate that infection may also cause leptospiral protein denaturation, and the HslU and HslV proteins of L. interrogans may compose a complex to degrade denatured proteins that enhances leptospiral survival in hosts. Here we show that leptospiral HslUV is an ATP dependent chaperone-peptidase complex containing ATPase associated with various cellular activity (AAA+) and N-terminal nucleophile (Ntn) hydrolase superfamily domains, respectively, which hydrolyzed casein and chymotrypsin-like substrates, and this hydrolysis was blocked by threonine protease inhibitors. The infection of J774A.1 macrophages caused the increase of leptospiral denatured protein aggresomes, but more aggresomes accumulated in hslUV gene-deleted mutant. The abundant denatured leptospiral proteins are involved in ribosomal structure, flagellar assembly, two-component signaling systems and transmembrane transport. Compared to the wild-type strain, infection of cells in vitro with the mutant resulted in a higher number of dead leptospires, less leptospiral colony-forming units and lower growth ability, but also displayed a lower half lethal dose, attenuated histopathological injury and decreased leptospiral loading in lungs, liver, kidneys, peripheral blood and urine in hamsters. Therefore, our findings confirmed that HslUV AAA+ chaperone-Ntn peptidase complex of L. interrogans contributes to leptospiral survival in hosts and transmission of leptospirosis. PMID- 29184155 TI - Isolation and molecular characterization of prevalent Fowl adenovirus strains in southwestern China during 2015-2016 for the development of a control strategy. AB - Fowl adenovirus (FAdV) has caused significant losses in chicken flocks throughout China in recent years. However, the current understanding of the genetic and pathogenic characteristics of the FAdV epidemic in southwestern China remains poorly understood. In this study, a total of 22 strains were isolated from liver samples of diseased chickens from farms in southwestern China. Phylogenetic analysis based on the hexon loop-1 gene showed that the 22 isolates were clustered into four distinct serotypes: FAdV serotype 4 (FAdV-4) (86.4%, 19/22), FAdV-2 (4.5%, 1/22), FAdV-8a (4.5%, 1/22), and FAdV-8b (4.5%, 1/22). FAdV-4 was the predominant serotype in southwestern China. Pathogenicity testing showed that the FAdV-4 serotype strain CH/GZXF/1602 and FAdV-8a strain CH/CQBS/1504 were pathogenic to chickens, with mortality rates reaching as high as 80% and 20%, respectively. The primary clinical feature observed following infection with strain CH/GZXF/1602 (FAdV-4) was hepatitis-hydropericardium syndrome, and that of strain CH/CQBS/1504 (FAdV-8a) was inclusion body hepatitis. Conversely, the FAdV 2 serotype strain CH/GZXF/1511 and FAdV-8b serotype strain CH/CQBS/1512 was not observed to be pathogenic in chickens. Then, CH/GZXF/1602 (FAdV-4) was selected for the preparation of an inactivated oil-emulsion vaccine. Immune studies on Partridge Shank broilers showed that a single dose immunization at 17 days of age could not only protect against homologous challenge with virulent FAdV-4 but also provided protection against clinical disease following challenge with the heterologous FAdV-8b virulent strain until 70 days of age. The characterization of newly prevalent FAdV strains provides a valuable reference for the development of an efficacious control strategy.

AB - Influenza H9N2 subtype viruses and their reassortants (such as H7N9) are posing increasing threats to birds and humans in China. During 2009-2013, multiple novel subtype viruses with H9N2 original genes emerged in China. Yet, the genetic evolution of H9N2 viruses in various host organisms in China has not been systematically investigated since 2009. In the present study, we performed large scale sequence analysis of H9N2 viral genomes from public databases, representing the spectrum of viruses isolated from birds, mammals and humans in China from 1994 to 2013, and updated the clade classification for each segment. We identified 117 distinct genotypes in 730 H9N2 viruses. We analyzed the sequences of all eight segments in each virus and found three important time points: the years 2000, 2006 and 2010. In the periods divided by these years, genotypic diversity, geographic distribution and host range changed considerably. Genotypic diversity fluctuated greatly in 2000 and 2006. Since 2010, a single genotype became predominant in poultry throughout China, and the eastern coastal region became the newly identified epidemic center. Throughout their 20-year prevalence in China, H9N2 influenza viruses have emerged and adapted from aquatic birds to chickens. The minor avian species and wild birds exacerbated H9N2 genotypes by providing diversified genes, and chickens were the most prevalent vector in which the viruses evolved and expanded their prevalence. It is the necessity for surveillance and disease control on live-bird markets, poultry farms and wild bird habitats in China. PMID- 29184158 TI - Meteorological factors affect the epidemiology of hemorrhagic fever with renal syndrome via altering the breeding and hantavirus-carrying states of rodents and mites: a 9 years' longitudinal study. AB - The incidence of hemorrhagic fever with renal syndrome (HFRS) in Qingdao, China was three times higher than that of the average national level. Here we characterized the epidemiology, ecological determinants and pathogen evolution of HFRS in Qingdao during 2007-2015. In this longitudinal study, a total of 1846 HFRS patients and 41 HFRS-related deaths were reported. HFRS in Qingdao peaked once a year in the fourth quarter. We built a time series generalized additive model, and found that meteorological factors in the previous quarter could accurately predict HFRS occurrence. To explore how meteorological factors influenced the epidemic of HFRS, we analyzed the relationship between meteorological factors and hantavirus-carrying states of the hosts (including rodents and shrews). Comprehensive analysis showed humidity was correlated to high host densities in the third quarter and high hantavirus-carrying rates of animal hosts in the third to fourth quarters, which might contribute to HFRS peak in the fourth quarter. We further compared the L segments of hantaviruses from HFRS patients, animal hosts and ectoparasites. Phylogenetic analysis showed that hantaviruses in gamasid and trombiculid mites were the same as those from the hosts. This indicated mites also contributed to the transmission of hantavirus. Furthermore, Hantaan virus from HFRS patients, hosts and mites in Qingdao formed a distinct phylogenetic cluster. A new clade of Seoul virus was also identified in the hosts. Overall, meteorological factors increase HFRS incidence possibly via facilitating hosts' reproduction and consequent mite-mediated hantavirus transmission. New hantavirus subtypes evolved in Qingdao represent new challenges of fighting against HFRS. PMID- 29184159 TI - Cell-free protein synthesis from non-growing, stressed Escherichia coli. AB - Cell-free protein synthesis is a versatile protein production system. Performance of the protein synthesis depends on highly active cytoplasmic extracts. Extracts from E. coli are believed to work best; they are routinely obtained from exponential growing cells, aiming to capture the most active translation system. Here, we report an active cell-free protein synthesis system derived from cells harvested at non-growth, stressed conditions. We found a downshift of ribosomes and proteins. However, a characterization revealed that the stoichiometry of ribosomes and key translation factors was conserved, pointing to a fully intact translation system. This was emphasized by synthesis rates, which were comparable to those of systems obtained from fast-growing cells. Our approach is less laborious than traditional extract preparation methods and multiplies the yield of extract per cultivation. This simplified growth protocol has the potential to attract new entrants to cell-free protein synthesis and to broaden the pool of applications. In this respect, a translation system originating from heat stressed, non-growing E. coli enabled an extension of endogenous transcription units. This was demonstrated by the sigma factor depending activation of parallel transcription. Our cell-free expression platform adds to the existing versatility of cell-free translation systems and presents a tool for cell-free biology. PMID- 29184160 TI - Fabrication-Method-Dependent Excited State Dynamics in CH3NH3PbI3 Perovskite Films. AB - Understanding the excited-state dynamics in perovskite photovoltaics is necessary for progress in these materials, but changes in dynamics depending on the fabrication processes used for perovskite photoactive layers remain poorly characterised. Here we report a comparative study on femtosecond transient absorption (TA) in CH3NH3PbI3 perovskite films fabricated by various solution processing methods. The grain sizes and the number of voids between grains on each film varied according to the film synthesis method. At the low excitation fluence of 0.37 MUJ cm-2, fast signal drops in TA dyanmics within 1.5 ps were observed in all perovskite films, but the signal drop magnitudes differed becuase of the variations in charge migration to trap states and band gap renormalisation. For high excitation fluences, the buil-up time of the TA signal was increased by the activated hot-phonon bottleneck, while the signal decay rate was accelerated by fluence-dependent high-order charge recombination. These fluence-dependent dynamics changed for different perovskite fabrication methords, indicating that the dynamics were affected by morphological features such as grain sizes and defects. PMID- 29184161 TI - Multiple-stressor effects in an apex predator: combined influence of pollutants and sea ice decline on lipid metabolism in polar bears. AB - There is growing evidence from experimental and human epidemiological studies that many pollutants can disrupt lipid metabolism. In Arctic wildlife, the occurrence of such compounds could have serious consequences for seasonal feeders. We set out to study whether organohalogenated compounds (OHCs) could cause disruption of energy metabolism in female polar bears (Ursus maritimus) from Svalbard, Norway (n = 112). We analyzed biomarkers of energy metabolism including the abundance profiles of nine lipid-related genes, fatty acid (FA) synthesis and elongation indices in adipose tissue, and concentrations of lipid related variables in plasma (cholesterol, high-density lipoprotein, triglycerides). Furthermore, the plasma metabolome and lipidome were characterized by low molecular weight metabolites and lipid fingerprinting, respectively. Polychlorinated biphenyls, chlordanes, brominated diphenyl ethers and perfluoroalkyl substances were significantly related to biomarkers involved in lipid accumulation, FA metabolism, insulin utilization, and cholesterol homeostasis. Moreover, the effects of pollutants were measurable at the metabolome and lipidome levels. Our results indicate that several OHCs affect lipid biosynthesis and catabolism in female polar bears. Furthermore, these effects were more pronounced when combined with reduced sea ice extent and thickness, suggesting that climate-driven sea ice decline and OHCs have synergistic negative effects on polar bears.

Dacarbazine nanoparticle and its cream were evaluated for morphology, drug load capacity, efficiency of nanoencapsulation and size of particle and zeta potential, Transmission Electron Microscopy (TEM), determination of pH, spreadability and viscosity, in vitro drug release capacity and its cytotoxic potential. The particle size of DZNP and DZNC was 16.3 +/- 8.1 nm and 16.9 +/- 7.8 nm respectively. pH value and spreadability of nanoparticle cream were found to be 6.7 +/- 0.14 g cm/sec and 55.23 +/- 3.13 g cm/sec respectively. Nanoencapsulation efficiency and Drug loading capacity were 67.4 +/- 3.5% and 6.73 mg/10 mg respectively. IC50 of dacarbazine nanoparticle was 0.19 mg/ml while it was 0.63 mg/ml for nanoparticle cream. It can be concluded that DZNP and its cream can be effectively used as a topical formulation for the treatment of melanoma.

AB - To determine the growth inhibition capability of all-trans retinoic acid (ATRA) with cytokine-induced killer cells (CIKs), we evaluated their effects, alone and in combination, on human lung carcinoma A549 cells. CIKs treated with ATRA significantly inhibited cell growth. Additionally, CIK with ATRA synergistically inhibited migration and invasiveness, colony formation of A549 and NCI-H520 cells. Furthermore, analysis of apoptosis markers Bcl-2, Bax, Survivin and cleaved Caspase-3 showed that Bcl-2 and Survivin mRNA levels significantly decreased, and that Bax mRNA significantly increased, in the CIK + ATRA-treated cells, with corresponding effects on their respective proteins. The involved mechanisms may be associated with upregulated expression of MHC class I-Related Chain (MICA) and interleukin (IL)-2. These results suggest that administration of combined CIK and ATRA is a potentially novel treatment for lung carcinoma. PMID- 29184164 TI - Correlates of compliance with recommended levels of physical activity in children. AB - The purpose of this study was to describe children's daily compliance with moderate-to-vigorous physical activity (MVPA) recommendations across a week in different parts of the world, and to identify individual- and school-level correlates that may explain differences in daily MVPA compliance. The sample included 6553 children aged 9-11 years from 12 countries, and multilevel statistical analyses were used, including both child- and school-level variables. Most children did not comply with the MVPA guidelines on a daily basis: Chinese children complied the least, whereas Finnish, Australian, Colombian, UK, and Kenyan children complied the most. Boys (rate ratio [RR] = 1.47) and children with higher unhealthy diet scores (RR = 1.08) complied more, but overweight/obese children (RR = 0.81), earlier maturing children (RR = 0.93), and those who spent more time in screen activities (RR = 0.98) and sleeping (RR = 0.96) had the lowest compliance. At the school level, children with access to playground or sport equipment (RR = 0.88, for both) tended to comply less, whereas those with access to a gymnasium outside the school hours complied more with the MVPA guidelines (RR = 1.14). Significant between-country differences in children's daily MVPA compliance were observed, reflecting not only site characteristics, but also the importance of individual traits and local school contexts. PMID- 29184165 TI - ATP1A3 mutations can cause progressive auditory neuropathy: a new gene of auditory synaptopathy. AB - The etiologies and prevalence of sporadic, postlingual-onset, progressive auditory neuropathy spectrum disorder (ANSD) have rarely been documented. Thus, we aimed to evaluate the prevalence and molecular etiologies of these cases. Three out of 106 sporadic progressive hearing losses turned out to manifest ANSD. Through whole exome sequencing and subsequent bioinformatics analysis, two out of the three were found to share a de novo variant, p.E818K of ATP1A3, which had been reported to cause exclusively CAPOS (cerebellar ataxia, areflexia, pes cavus, optic atrophy, and sensorineural hearing loss) syndrome. However, hearing loss induced by CAPOS has never been characterized to date. Interestingly, the first proband did not manifest any features of CAPOS, except subclinical areflexia; however, the phenotypes of second proband was compatible with that of CAPOS, making this the first reported CAPOS allele in Koreans. This ANSD phenotype was compatible with known expression of ATP1A3 mainly in the synapse between afferent nerve and inner hair cells. Based on this, cochlear implantation (CI) was performed in the first proband, leading to remarkable benefits. Collectively, the de novo ATP1A3 variant can cause postlingual-onset auditory synaptopathy, making this gene a significant contributor to sporadic progressive ANSD and a biomarker ensuring favorable short-term CI outcomes. PMID- 29184166 TI - Quantitative, in situ analysis of mRNAs and proteins with subcellular resolution. AB - We describe here a method, termed immunoFISH, for simultaneous in situ analysis of the composition and distribution of proteins and individual RNA transcripts in single cells. Individual RNA molecules are labeled by hybridization and target proteins are concurrently stained using immunofluorescence. Multicolor fluorescence images are acquired and analyzed to determine the abundance, composition, and distribution of hybridized probes and immunofluorescence. We assessed the ability of immunoFISH to simultaneous quantify protein and transcript levels and distribution in cultured HER2 positive breast cancer cells and human breast tumor samples. We demonstrated the utility of this assay in several applications including demonstration of the existence of a layer of normal myoepithelial KRT14 expressing cells that separate HER2+ cancer cells from the stromal and immune microenvironment in HER2+ invasive breast cancer. Our studies show that immunoFISH provides quantitative information about the spatial heterogeneity in transcriptional and proteomic features that exist between and within cells. PMID- 29184167 TI - Effect of nebivolol or atenolol vs. placebo on cardiovascular health in subjects with borderline blood pressure: the EVIDENCE study. AB - Pharmacotherapy to protect the arteries may be appropriate for individuals with high-normal blood pressure who are at risk for future cardiovascular disease (CVD). Nebivolol (NEB) in contrast to atenolol (ATE) may have a beneficial effect on endothelial function and may be more effective than ATE in preventing CVD. Sixty subjects with preHTN or borderline BP and abnormal small artery elasticity (SAE) underwent evaluation with 10 tests, including large and small artery elasticity, resting and treadmill exercise BP, carotid intimal-media thickness, retinal vascular photography, micro-albuminuria, electrocardiography, echocardiography, and plasma B-type natriuretic peptide level. Each test scored as normal (0), borderline (1), or abnormal (2), and the total disease score (DS) was calculated by adding the test scores. Subjects were randomized double-blind to placebo (PLAC, n = 22), NEB 5/10 mg/day (n = 20), or ATE 25/50 mg/day (n = 18) once daily for 9 months. After 9 months, in the group receiving NEB the mean (standard deviation) DS decreased from baseline 4.3 (2.6) to 2.8 (2.4) (P < 0.007), with ATE from 5.4 (2.5) to 3.5 (1.9) (P = 0.0006), and with PLAC from 5.2 (3.0) to 4.5 (2.6) (P = 0.18). SAE increased in the NEB group from 6.0 (2.2) to 8.4 (3.4) ml/mmHg * 100 (P = 0.0001), whereas there was no significant change in the ATE and PLAC groups. Thus, nebivolol improves small artery function more than atenolol in asymptomatic subjects with preHTN or borderline BP, despite their similar BP-lowering effect. PMID- 29184168 TI - Mucopolysaccharidosis at play? PMID- 29184169 TI - NMNAT1 variants cause cone and cone-rod dystrophy. AB - Cone and cone-rod dystrophies (CD and CRD, respectively) are degenerative retinal diseases that predominantly affect the cone photoreceptors. The underlying disease gene is not known in approximately 75% of autosomal recessive cases. Variants in NMNAT1 cause a severe, early-onset retinal dystrophy called Leber congenital amaurosis (LCA). We report two patients where clinical phenotyping indicated diagnoses of CD and CRD, respectively. NMNAT1 variants were identified, with Case 1 showing an extremely rare homozygous variant c.[271G > A] p.(Glu91Lys) and Case 2 compound heterozygous variants c.[53 A > G];[769G > A] p.(Asn18Ser);(Glu257Lys). The detailed variant analysis, in combination with the observation of an associated macular atrophy phenotype, indicated that these variants were disease-causing. This report demonstrates that the variants in NMNAT1 may cause CD or CRD associated with macular atrophy. Genetic investigations of the patients with CD or CRD should include NMNAT1 in the genes examined. PMID- 29184170 TI - 19p13 microduplications encompassing NFIX are responsible for intellectual disability, short stature and small head circumference. AB - Syndromes caused by copy number variations are described as reciprocal when they result from deletions or duplications of the same chromosomal region. When comparing the phenotypes of these syndromes, various clinical features could be described as reversed, probably due to the opposite effect of these imbalances on the expression of genes located at this locus. The NFIX gene codes for a transcription factor implicated in neurogenesis and chondrocyte differentiation. Microdeletions and loss of function variants of NFIX are responsible for Sotos syndrome-2 (also described as Malan syndrome), a syndromic form of intellectual disability associated with overgrowth and macrocephaly. Here, we report a cohort of nine patients harboring microduplications encompassing NFIX. These patients exhibit variable intellectual disability, short stature and small head circumference, which can be described as a reversed Sotos syndrome-2 phenotype. Strikingly, such a reversed phenotype has already been described in patients harboring microduplications encompassing NSD1, the gene whose deletions and loss of-function variants are responsible for classical Sotos syndrome. Even though the type/contre-type concept has been criticized, this model seems to give a plausible explanation for the pathogenicity of 19p13 microduplications, and the common phenotype observed in our cohort. PMID- 29184171 TI - Points to consider for laboratories reporting results from diagnostic genomic sequencing. AB - Although NGS technologies are well-embedded in the clinical setting for identification of genetic causes of disease, guidelines issued by professional bodies are inconsistent regarding some aspects of reporting results. Most recommendations do not give detailed guidance about whether variants of uncertain significance (VUS) should be reported by laboratory personnel to clinicians, and give conflicting messages regarding whether unsolicited findings (UF) should be reported. There are also differences both in their recommendations regarding whether actively searching for secondary findings (SF) is appropriate, and in the extent to which they address the duty (or lack thereof) to reanalyse variants when new information arises. An interdisciplinary working group considered the current guidelines, their own experiences, and data from a recent qualitative study to develop a set of points to consider for laboratories reporting results from diagnostic NGS. These points to consider fall under six categories: (i) Testing approaches and technologies used, (ii) Approaches for VUS; (iii) Approaches for reporting UF, (iv) Approaches regarding SF; (v) Reanalysis of data & re-contact; and vi) Minors. While it is unclear whether uniformity in reporting across all laboratories is desirable, we hope these points to consider will be useful to diagnostic laboratories as they develop their processes for making decisions about reporting VUS and UF from NGS in the diagnostic context.

PMID- 29184182 TI - A quantitative method for microstructural analysis of myelinated axons in the injured rodent brain. AB - MRI studies (e.g. using diffusion tensor imaging) revealed that injury to white matter tracts, as observed in for instance perinatal white matter injury and multiple sclerosis, leads to compromised microstructure of myelinated axonal tracts. Alterations in white matter microstructure are also present in a wide range of neurological disorders including autism-spectrum disorders, schizophrenia and ADHD. Whereas currently myelin quantity measures are often used in translational animal models of white matter disease, it can be an important valuable addition to study the microstructural organization of myelination patterns in greater detail. Here, we describe methods to extensively study the microstructure of cortical myelination by immunostaining for myelin. To validate these methods, we carefully analyzed the organization of myelinated axons running from the external capsule towards the outer layers of the cortex in three rodent models of neonatal brain injury and in an adult stroke model, that have all been associated with myelination impairments. This unique, relatively easy and sensitive methodology can be applied to study subtle differences in myelination patterns in animal models in which aberrations in myelination integrity are suspected. Importantly, the described methods can be applied to determine efficacy of novel experimental treatments on microstructural organization of cortical myelination.

AB - Optogenetics and chemogenetics comprise a wide variety of applications in which genetically encoded actuators and indicators are used to modulate and monitor activity with high cellular specificity. Over the past 10 years, development of these genetically encoded tools has contributed tremendously to our understanding of integrated physiology. In concert with the continued refinement of probes, strategies to target transgene expression to specific cell types have also made much progress in the past 20 years. In addition, the successful implementation of optogenetic and chemogenetic techniques thrives thanks to ongoing advances in live imaging microscopy and optical technology. Although innovation of optogenetic and chemogenetic methods has been primarily driven by researchers studying the central nervous system, these techniques also hold great promise to boost research in neurogastroenterology. In this Review, we describe the different classes of tools that are currently available and give an overview of the strategies to target them to specific cell types in the gut wall. We discuss the possibilities and limitations of optogenetic and chemogenetic technology in the gut and provide an overview of their current use, with a focus on the enteric nervous system. Furthermore, we suggest some experiments that can advance our understanding of how the intrinsic and extrinsic neural networks of the gut control gastrointestinal function.

PMID- 29184185 TI - Cellular senescence in gastrointestinal diseases: from pathogenesis to therapeutics. AB - Senescence is a durable cell cycle arrest that can be induced in response to various stress factors, such as telomere erosion, DNA damage or the aberrant activation of oncogenes. In addition to its well-established role as a stress response programme, research has revealed important physiological roles of senescence in nondisease settings, such as embryonic development, wound healing, tissue repair and ageing. Senescent cells secrete various cytokines, chemokines, matrix remodelling proteases and growth factors, a phenotype collectively referred to as the senescence-associated secretory phenotype. These factors evoke immune responses that, depending on the pathophysiological context, can either prevent or even fuel disease and tumorigenesis. Remarkably, even the gut microbiota can influence senescence in various organs. In this Review, we provide an introduction to cellular senescence, addressed particularly to gastroenterologists and hepatologists, and discuss the implications of senescence for the pathogenesis of malignant and nonmalignant gastrointestinal and hepatobiliary diseases. We conclude with an outlook on how modulation of cellular senescence might be used for therapeutic purposes. PMID- 29184189 TI - Ultra-short pulse propagation model for multi-core fibers based on local modes. AB - Multi-core fibers (MCFs) have sparked a new paradigm in optical communications and open new possibilities and applications in experimental physics and other fields of science, such as biological and medical imaging. In many of these cases, ultra-short pulse propagation is revealed as a key factor that enables us to exploit the full potential of this technology. Unfortunately, the propagation of such pulses in real MCFs has not yet been modelled considering polarization effects or typical random medium perturbations, which usually give rise to both longitudinal and temporal birefringent effects. Using the concept of local modes, we develop here an accurate ultra-short pulse propagation model that rigorously accounts for these phenomena in single-mode MCFs. Based on this theory, we demonstrate analytically and numerically the intermodal dispersion between different LP01 polarized core modes induced by these random perturbations when propagating femtosecond pulses in the linear and nonlinear fiber regimes. The ever-decreasing core-to-core distance significantly enhances the intermodal dispersion induced by these birefringent effects, which can become the major physical impairment in the single-mode regime. To demonstrate the power of our model, we give explicit strategies to reduce the impact of this optical impairment by increasing the MCF perturbations. PMID- 29184188 TI - A Novel Communication Value Task Demonstrates Evidence of Response Bias in Cases with Presbyacusis. AB - Decision-making about the expected value of an experience or behavior can explain hearing health behaviors in older adults with hearing loss. Forty-four middle aged to older adults (68.45 +/- 7.73 years) performed a task in which they were asked to decide whether information from a surgeon or an administrative assistant would be important to their health in hypothetical communication scenarios across visual signal-to-noise ratios (SNR). Participants also could choose to view the briefly presented sentences multiple times. The number of these effortful attempts to read the stimuli served as a measure of demand for information to make a health importance decision. Participants with poorer high frequency hearing more frequently decided that information was important to their health compared to participants with better high frequency hearing. This appeared to reflect a response bias because participants with high frequency hearing loss demonstrated shorter response latencies when they rated the sentences as important to their health. However, elevated high frequency hearing thresholds did not predict demand for information to make a health importance decision. The results highlight the utility of a performance-based measure to characterize effort and expected value from performing tasks in older adults with hearing loss. PMID- 29184191 TI - A micro-Raman study of exfoliated few-layered n-type Bi2 Te2.7Se0.3. AB - Previously we showed that the thermoelectric (TE) performance of bulk n-type Bi2Te2.7Se0.3 can be enhanced by subjecting it to a combined process of chemical or mechanical exfoliation (C/ME) followed by a rapid densification and restacking of the exfoliated layers via the spark-plasma-sintering technique (SPS). Here, we present a systematic micro-Raman study of two-dimensional flakes of n-type Bi2Te2.7Se0.3 produced by the C/ME process, as a function of the flake thickness. We found Raman evidence for flakes with: (i) integer number of quintuples which exhibited a strong electron-phonon coupling, and (ii) non-integer number of quintuples, or sub-quintuples which exhibited the forbidden IR active mode due to symmetry lowering. Detailed atomic force microscopy was used to confirm the number of quintuples in all flakes examined in this study. The restacking and densification of these flakes by SPS promoted the formation of charged grain boundaries, which led to the enhanced TE properties via the energy filtering process. PMID- 29184190 TI - Bacterial endosymbionts influence host sexuality and reveal reproductive genes of early divergent fungi. AB - Many heritable mutualisms, in which beneficial symbionts are transmitted vertically between host generations, originate as antagonisms with parasite dispersal constrained by the host. Only after the parasite gains control over its transmission is the symbiosis expected to transition from antagonism to mutualism. Here, we explore this prediction in the mutualism between the fungus Rhizopus microsporus (Rm, Mucoromycotina) and a beta-proteobacterium Burkholderia, which controls host asexual reproduction. We show that reproductive addiction of Rm to endobacteria extends to mating, and is mediated by the symbiont gaining transcriptional control of the fungal ras2 gene, which encodes a GTPase central to fungal reproductive development. We also discover candidate G protein-coupled receptors for the perception of trisporic acids, mating pheromones unique to Mucoromycotina. Our results demonstrate that regulating host asexual proliferation and modifying its sexual reproduction are sufficient for the symbiont's control of its own transmission, needed for antagonism-to mutualism transition in heritable symbioses. These properties establish the Rm Burkholderia symbiosis as a powerful system for identifying reproductive genes in Mucoromycotina. PMID- 29184192 TI - Robust generation of entangled state via ground-state antiblockade of Rydberg atoms. AB - We propose a mechanism of ground-state antiblockade of Rydberg atoms, which is then exploited to prepare two-atom entangled state via three different kinds of pulses. First we use the pulses in the form of sin2 and cos2 functions and obtain a maximally entangled state at an accurate interaction time. Then the method of stimulated Raman adiabatic passage (STIRAP) is adopted for the entanglement generation, which is immune to the fluctuations of revelent parameters but requires a long time. Finally we capitalize the advantages of the former two methods and employ shortcuts to adiabatic passage (STAP) to generate the maximal entanglement. The strictly numerical simulation reveals that the current scheme is robust against spontaneous emission of atoms due to the virtual excitation of Rydberg states, and all of the above methods favor a high fidelity with the present experimental technology. PMID- 29184193 TI - Proof of concept for a passive sampler for monitoring of gaseous elemental mercury in artisanal gold mining. AB - Mercury emissions from artisanal gold mining operations occurring in roughly 80 developing countries are a major workplace health hazard for millions of people as well as the largest contributor to global mercury pollution. There are no portable, cheap, and rapid methods able to inform workers or health practitioners of mercury exposure on site in remote locations. In this work, a proof of concept for a miniaturized mercury sampler, prepared by the direct reduction of gold into the porous nanostructures of Vycor glass (PVG), is introduced. Mercury retention on the PVG/Au sampler induces significant color changes, due to the formation of Au-Hg amalgam that affects the surface plasmon resonance characteristics of the material. The color change can potentially be quantified by the analysis of pictures obtained with a cell phone camera rapidly and onsite. Laboratory experiments showed the viability of using PVG/Au as passive sampler for monitoring of Hg degrees . PVG/Au samplers were then deployed in an artisanal and small-scale gold mining (ASGM) operations in Burkina Faso and it was able to indicate personal mercury exposures. The amount of mercury quantified in the samplers for all miners was higher than the current personal exposure limit set by the US Occupational Safety & Health Administration (OSHA). PMID- 29184194 TI - Interventions for management of post-stroke depression: A Bayesian network meta analysis of 23 randomized controlled trials. AB - Post-stroke depression (PSD) is an important complication of stroke, leading to increased disability and mortality. Given that there is no consensus on which treatment is optimal for PSD, we aimed to evaluate the relative efficacies of available pharmacological and non-pharmacological interventions. We conducted a network meta-analysis to incorporate evidence from relevant trials and provide direct and indirect comparisons. We searched PubMed, Cochrane Library Central Register of Controlled Trials, and Embase until November 1, 2016 for randomized controlled trials involving different pharmacological and non-pharmacological PSD treatment interventions. The primary outcome was reduction in the Hamilton depression scale (HAMD) score. This study is registered with PROSPERO (number, CRD42016049049). Of a total of 1,152 studies, 23 randomized trials comprising 1,542 participants were included. Nine PSD treatment interventions were considered. Noradrenaline reuptake inhibitor (NRI) was associated with the highest reduction in the HAMD score, followed by tricyclic antidepressant (TCA), psychotherapy plus antidepressant, and selective serotonin reuptake inhibitor (SSRI). This study indicated that NRIs, SSRIs, and TCAs are associated with a considerable higher HAMD score reduction compared with the control treatment. rTMS is a beneficial therapeutic approach for managing PSD to obtain good response to treatments compared with the control treatment.

AB - The prefrontal cortex maintains working memory information in the presence of distracting stimuli. It has long been thought that sustained activity in individual neurons or groups of neurons was responsible for maintaining information in the form of a persistent, stable code. Here we show that, upon the presentation of a distractor, information in the lateral prefrontal cortex was reorganized into a different pattern of activity to create a morphed stable code without losing information. In contrast, the code in the frontal eye fields persisted across different delay periods but exhibited substantial instability and information loss after the presentation of a distractor. We found that neurons with mixed-selective responses were necessary and sufficient for the morphing of code and that these neurons were more abundant in the lateral prefrontal cortex than the frontal eye fields. This suggests that mixed selectivity provides populations with code-morphing capability, a property that may underlie cognitive flexibility. PMID- 29184195 TI - Chromatin dependencies in cancer and inflammation. AB - Multiple cell-signalling pathways converge on chromatin to induce gene expression programmes. The inducible transcriptional programmes that are established as a result of inflammatory or oncogenic signals are controlled by shared chromatin regulators. Therapeutic targeting of such chromatin dependencies has proved effective for controlling tumorigenesis and for preventing immunopathologies that are driven by overt inflammation. In this Review, we discuss how chromatin dependencies are established to regulate the expression of key oncogenes and inflammation-promoting genes and how a better mechanistic understanding of such chromatin dependencies can be leveraged to improve the magnitude, timing, duration and selectivity of cell responses with the aim of minimizing unwanted cellular and systemic effects. Recently, exciting progress has been made in cancer immunotherapy and in the development of drugs that target chromatin regulators. We discuss recent advances in clinical trials and the challenge of combining immune-cell-based therapies and epigenetic therapies to improve human health. PMID- 29184198 TI - Activation of planarian TRPA1 by reactive oxygen species reveals a conserved mechanism for animal nociception. AB - All animals must detect noxious stimuli to initiate protective behavior, but the evolutionary origin of nociceptive systems is not well understood. Here we show that noxious heat and irritant chemicals elicit robust escape behaviors in the planarian Schmidtea mediterranea and that the conserved ion channel TRPA1 is required for these responses. TRPA1-mutant Drosophila flies are also defective in noxious-heat responses. We find that either planarian or human TRPA1 can restore noxious-heat avoidance to TRPA1-mutant Drosophila, although neither is directly activated by heat. Instead, our data suggest that TRPA1 activation is mediated by H2O2 and reactive oxygen species, early markers of tissue damage rapidly produced as a result of heat exposure. Together, our data reveal a core function for TRPA1 in noxious heat transduction, demonstrate its conservation from planarians to humans, and imply that animal nociceptive systems may share a common ancestry, tracing back to a progenitor that lived more than 500 million years ago. PMID- 29184199 TI - Thalamic inhibition regulates critical-period plasticity in visual cortex and thalamus. AB - During critical periods of development, experience shapes cortical circuits, resulting in the acquisition of functions used throughout life. The classic example of critical-period plasticity is ocular dominance (OD) plasticity, which optimizes binocular vision but can reduce the responsiveness of the primary visual cortex (V1) to an eye providing low-grade visual input. The onset of the critical period of OD plasticity involves the maturation of inhibitory synapses within V1, specifically those containing the GABAA receptor alpha1 subunit. Here we show that thalamic relay neurons in mouse dorsolateral geniculate nucleus (dLGN) also undergo OD plasticity. This process depends on thalamic alpha1 containing synapses and is required for consolidation of the OD shift in V1 during long-term deprivation. Our findings demonstrate that thalamic inhibitory circuits play a central role in the regulation of the critical period. This has far-reaching consequences for the interpretation of studies investigating the molecular and cellular mechanisms regulating critical periods of brain development. PMID- 29184200 TI - Altered cerebellar connectivity in autism and cerebellar-mediated rescue of autism-related behaviors in mice. AB - Cerebellar abnormalities, particularly in Right Crus I (RCrusI), are consistently reported in autism spectrum disorders (ASD). Although RCrusI is functionally connected with ASD-implicated circuits, the contribution of RCrusI dysfunction to ASD remains unclear. Here neuromodulation of RCrusI in neurotypical humans resulted in altered functional connectivity with the inferior parietal lobule, and children with ASD showed atypical functional connectivity in this circuit. Atypical RCrusI-inferior parietal lobule structural connectivity was also evident in the Purkinje neuron (PN) TscI ASD mouse model. Additionally, chemogenetically mediated inhibition of RCrusI PN activity in mice was sufficient to generate ASD related social, repetitive, and restricted behaviors, while stimulation of RCrusI PNs rescued social impairment in the PN TscI ASD mouse model. Together, these studies reveal important roles for RCrusI in ASD-related behaviors. Further, the rescue of social behaviors in an ASD mouse model suggests that investigation of the therapeutic potential of cerebellar neuromodulation in ASD may be warranted. PMID- 29184201 TI - Elucidating the underlying components of food valuation in the human orbitofrontal cortex. AB - The valuation of food is a fundamental component of our decision-making. Yet little is known about how value signals for food and other rewards are constructed by the brain. Using a food-based decision task in human participants, we found that subjective values can be predicted from beliefs about constituent nutritive attributes of food: protein, fat, carbohydrates and vitamin content. Multivariate analyses of functional MRI data demonstrated that, while food value is represented in patterns of neural activity in both medial and lateral parts of the orbitofrontal cortex (OFC), only the lateral OFC represents the elemental nutritive attributes. Effective connectivity analyses further indicate that information about the nutritive attributes represented in the lateral OFC is integrated within the medial OFC to compute an overall value. These findings provide a mechanistic account for the construction of food value from its constituent nutrients. PMID- 29184202 TI - The central amygdala controls learning in the lateral amygdala. AB - Experience-driven synaptic plasticity in the lateral amygdala is thought to underlie the formation of associations between sensory stimuli and an ensuing threat. However, how the central amygdala participates in such a learning process remains unclear. Here we show that PKC-delta-expressing central amygdala neurons are essential for the synaptic plasticity underlying learning in the lateral amygdala, as they convey information about the unconditioned stimulus to lateral amygdala neurons during fear conditioning. PMID- 29184203 TI - Arid1b haploinsufficiency disrupts cortical interneuron development and mouse behavior. AB - Haploinsufficiency of the AT-rich interactive domain 1B (ARID1B) gene causes autism spectrum disorder and intellectual disability; however, the neurobiological basis for this is unknown. Here we generated Arid1b-knockout mice and examined heterozygotes to model human patients. Arid1b-heterozygous mice showed a decreased number of cortical GABAergic interneurons and reduced proliferation of interneuron progenitors in the ganglionic eminence. Arid1b haploinsufficiency also led to an imbalance between excitatory and inhibitory synapses in the cerebral cortex. Furthermore, we found that Arid1b haploinsufficiency suppressed histone H3 lysine 9 acetylation (H3K9ac) overall and particularly reduced H3K9ac of the Pvalb promoter, resulting in decreased transcription. Arid1b-heterozygous mice exhibited abnormal cognitive and social behaviors, which were rescued by treatment with a positive allosteric GABAA receptor modulator. Our results demonstrate a critical role for Arid1b in interneuron development and behavior and provide insight into the pathogenesis of autism spectrum disorder and intellectual disability.

AB - Spontaneous fluctuations in hemodynamic signals in the absence of a task or overt stimulation are used to infer neural activity. We tested this coupling by simultaneously measuring neural activity and changes in cerebral blood volume (CBV) in the somatosensory cortex of awake, head-fixed mice during periods of true rest and during whisker stimulation and volitional whisking. We found that neurovascular coupling was similar across states and that large, spontaneous CBV changes in the absence of sensory input were driven by volitional whisker and body movements. Hemodynamic signals during periods of rest were weakly correlated with neural activity. Spontaneous fluctuations in CBV and vessel diameter persisted when local neural spiking and glutamatergic input were blocked, as well as during blockade of noradrenergic receptors, suggesting a non-neuronal origin for spontaneous CBV fluctuations. Spontaneous hemodynamic signals reflect a combination of behavior, local neural activity, and putatively non-neural processes. PMID- 29184206 TI - A multiregional proteomic survey of the postnatal human brain. AB - Detailed observations of transcriptional, translational and post-translational events in the human brain are essential to improving our understanding of its development, function and vulnerability to disease. Here, we exploited label-free quantitative tandem mass-spectrometry to create an in-depth proteomic survey of regions of the postnatal human brain, ranging in age from early infancy to adulthood. Integration of protein data with existing matched whole-transcriptome sequencing (RNA-seq) from the BrainSpan project revealed varied patterns of protein-RNA relationships, with generally increased magnitudes of protein abundance differences between brain regions compared to RNA. Many of the differences amplified in protein data were reflective of cytoarchitectural and functional variation between brain regions. Comparing structurally similar cortical regions revealed significant differences in the abundances of receptor associated and resident plasma membrane proteins that were not readily observed in the RNA expression data. PMID- 29184207 TI - Lateral geniculate neurons projecting to primary visual cortex show ocular dominance plasticity in adult mice. AB - Experience-dependent plasticity in the mature visual system is widely considered to be cortical. Using chronic two-photon Ca2+ imaging of thalamic afferents in layer 1 of binocular visual cortex, we provide evidence against this tenet: the respective dorsal lateral geniculate nucleus (dLGN) cells showed pronounced ocular dominance (OD) shifts after monocular deprivation in adult mice. Most (86%), but not all, of dLGN cell boutons were monocular during normal visual experience. Following deprivation, initially deprived-eye-dominated boutons reduced or lost their visual responsiveness to that eye and frequently became responsive to the non-deprived eye. This cannot be explained by eye-specific cortical changes propagating to dLGN via cortico-thalamic feedback because the shift in dLGN responses was largely resistant to cortical inactivation using the GABAA receptor agonist muscimol. Our data suggest that OD shifts observed in the binocular visual cortex of adult mice may at least partially reflect plasticity of eye-specific inputs onto dLGN neurons. PMID- 29184208 TI - Temporally precise single-cell-resolution optogenetics. AB - Optogenetic control of individual neurons with high temporal precision within intact mammalian brain circuitry would enable powerful explorations of how neural circuits operate. Two-photon computer-generated holography enables precise sculpting of light and could in principle enable simultaneous illumination of many neurons in a network, with the requisite temporal precision to simulate accurate neural codes. We designed a high-efficacy soma-targeted opsin, finding that fusing the N-terminal 150 residues of kainate receptor subunit 2 (KA2) to the recently discovered high-photocurrent channelrhodopsin CoChR restricted expression of this opsin primarily to the cell body of mammalian cortical neurons. In combination with two-photon holographic stimulation, we found that this somatic CoChR (soCoChR) enabled photostimulation of individual cells in mouse cortical brain slices with single-cell resolution and <1-ms temporal precision. We used soCoChR to perform connectivity mapping on intact cortical circuits. PMID- 29184210 TI - Thalamic functions in distributed cognitive control. AB - Cognition can be conceptualized as a set of algorithmic control functions whose real-time deployment determines how an organism stores and uses information to guide thought and action. A subset of these functions is required for goal directed selection and amplification of sensory signals-broadly referred to as attention-and for its flexible control and its interaction with processes such as working memory and decision making. While the contribution of recurrent cortical microcircuits to cognition has been extensively studied, the role of the thalamus is just beginning to be elucidated. Here we highlight recent studies across rodents and primates showing how thalamus contributes to attentional control. In addition to high-fidelity information relay to or between cortical regions, thalamic circuits shift and sustain functional interactions within and across cortical areas. This thalamic process enables rapid coordination of spatially segregated cortical computations, thereby constructing task-relevant functional networks. Because such function may be critical for cognitive flexibility, clarifying its mechanisms will likely expand our basic understanding of cognitive control and its perturbation in disease. PMID- 29184209 TI - A craniofacial-specific monosynaptic circuit enables heightened affective pain. AB - Humans often rank craniofacial pain as more severe than body pain. Evidence suggests that a stimulus of the same intensity induces stronger pain in the face than in the body. However, the underlying neural circuitry for the differential processing of facial versus bodily pain remains unknown. Interestingly, the lateral parabrachial nucleus (PBL), a critical node in the affective pain circuit, is activated more strongly by noxious stimulation of the face than of the hindpaw. Using a novel activity-dependent technology called CANE developed in our laboratory, we identified and selectively labeled noxious-stimulus-activated PBL neurons and performed comprehensive anatomical input-output mapping. Surprisingly, we uncovered a hitherto uncharacterized monosynaptic connection between cranial sensory neurons and the PBL-nociceptive neurons. Optogenetic activation of this monosynaptic craniofacial-to-PBL projection induced robust escape and avoidance behaviors and stress calls, whereas optogenetic silencing specifically reduced facial nociception. The monosynaptic circuit revealed here provides a neural substrate for heightened craniofacial affective pain.

PMID- 29184212 TI - Oxytocin-receptor-expressing neurons in the parabrachial nucleus regulate fluid intake. AB - Brain regions that regulate fluid satiation are not well characterized, yet are essential for understanding fluid homeostasis. We found that oxytocin-receptor expressing neurons in the parabrachial nucleus of mice (OxtrPBN neurons) are key regulators of fluid satiation. Chemogenetic activation of OxtrPBN neurons robustly suppressed noncaloric fluid intake, but did not decrease food intake after fasting or salt intake following salt depletion; inactivation increased saline intake after dehydration and hypertonic saline injection. Under physiological conditions, OxtrPBN neurons were activated by fluid satiation and hypertonic saline injection. OxtrPBN neurons were directly innervated by oxytocin neurons in the paraventricular hypothalamus (OxtPVH neurons), which mildly attenuated fluid intake. Activation of neurons in the nucleus of the solitary tract substantially suppressed fluid intake and activated OxtrPBN neurons. Our results suggest that OxtrPBN neurons act as a key node in the fluid satiation neurocircuitry, which acts to decrease water and/or saline intake to prevent or attenuate hypervolemia and hypernatremia.

AB - Aiming at improved specificity, nanoparticle assisted polymerase chain reaction (PCR) has been widely studied and shown to improve PCR. However, the reliability and mechanism of this method are still controversial. Here, we demonstrated that 1 MUg/mL of graphene oxide (GO) effectively enhances the specificity of the error prone multi-round PCR. Mismatched primers were designed as interference to produce nonspecific products when the same amounts of matched and mismatched primers were added into semi-multiplex PCR. It was found that GO can enhance specificity by suppressing the amplification of mismatched primers. We monitored the primer-template-polymerase-GO interactions involved in the PCR using a capillary electrophoresis/laser-induced fluorescence polarization (CE-LIFP) assay. The results showed that the addition of GO promoted the formation of a matched primer-template complex, but suppressed the formation of a mismatched primer-template complex during PCR, suggesting that interactions between the primers and GO play an essential role. Furthermore, we successfully amplified the FOXL2 gene from PEGFP-N1 vectors using GO to eliminate the nonspecific products in PCR. Taken together, these results suggest that the GO can be used as an efficient additive for improving the conventional PCR system. PMID- 29184215 TI - Social stress induces neurovascular pathology promoting depression. AB - Studies suggest that heightened peripheral inflammation contributes to the pathogenesis of major depressive disorder. We investigated the effect of chronic social defeat stress, a mouse model of depression, on blood-brain barrier (BBB) permeability and infiltration of peripheral immune signals. We found reduced expression of the endothelial cell tight junction protein claudin-5 (Cldn5) and abnormal blood vessel morphology in nucleus accumbens (NAc) of stress-susceptible but not resilient mice. CLDN5 expression was also decreased in NAc of depressed patients. Cldn5 downregulation was sufficient to induce depression-like behaviors following subthreshold social stress whereas chronic antidepressant treatment rescued Cldn5 loss and promoted resilience. Reduced BBB integrity in NAc of stress-susceptible or mice injected with adeno-associated virus expressing shRNA against Cldn5 caused infiltration of the peripheral cytokine interleukin-6 (IL-6) into brain parenchyma and subsequent expression of depression-like behaviors. These findings suggest that chronic social stress alters BBB integrity through loss of tight junction protein Cldn5, promoting peripheral IL-6 passage across the BBB and depression. PMID- 29184217 TI - Increased sensibility to acute acoustic and blast trauma among patients with acoustic neuroma. AB - The article shows 2 cases of unusual presentation of acute acoustic trauma and blast injury due to occupational exposure. In the case of both patients the range of impaired frequencies in pure tone audiograms was atypical for this kind of causative factor. Both patients had symmetrical hearing before the accident (which was confirmed by provided results of hearing controls during their employment). A history of noise/blast exposure, the onset of symptoms directly after harmful exposure, symmetrical hearing before the trauma documented with audiograms, directed initial diagnosis towards acoustic/blast trauma, however, of atypical course. Acute acoustic and blast trauma and coexisting acoustic neuroma (AN) contributed to, and mutually modified, the course of sudden hearing loss. In the literature there are some reports pointing to a higher sensitivity to acoustic trauma in the case of patients with AN and, on the other hand, indicating noise as one of the causative factors in AN.

AB - BACKGROUND: The aim of the paper is to present the Polish adaptation of the Humor Climate Questionnaire (HCQ), designed to measure humor as organizational climate feature. MATERIAL AND METHODS: The authors employed back-translation and independent judges method to choose the best version of the translated items. The psychometric properties of HCQ were estimated on the basis of 2 samples: the basic group of employees (N = 217) and the group of employees who had completed the survey twice (N = 55). RESULTS: The results of statistical analyses proved that HCQ is a reliable tool. Explorative Factor Analysis supported the 4-factor structure of the original method's theoretical model. The validity of the subscales is high, Cronbach's alpha varied from 0.8 to 0.9. The directions and values of intercorrelations between subscales were similar to those of the English version. The Humor Climate Questionnaire is a relatively time-stable tool (r = 0.44-0.74). CONCLUSIONS: Polish adaptation is reliable and applicable for cross-sectional studies. The obtained results are comparable to the characteristics of the original version. However, the results of factor analysis show that the data do not fully fit the theoretical model.

AB - Quality and biochemical changes of 'Hindi-Besennara' mangoes in response to chitosan, gallic acid (GA) and chitosan gallate (CG) postharvest dipping were studied during 2 weeks of storage at 20 +/- 2 degrees C and 60-70% RH. Both GA and CG lowered decay and weight loss during storage. Chitosan and GA at high level and CG at both level maintained higher membrane stability index of peel than control. Fruits treated only CG and GA at high level and chitosan at both levels retained higher acidity and vitamin C but lower pH and total soluble solids (TSS) than control. All treatments resulted with fruits with higher flesh firmness and lower TSS/acid ratio than untreated fruits. GA at both rates gave lower total phenols after 1 week of storage than control. Both levels of GA and low level of chitosan resulted with fruits with higher antioxidant capacity (lower IC50 values) after 1 week of storage than control. All treatments decreased alpha-amylase activity of fruit peel compared to control. CG and GA at high level and chitosan at low level increased peroxidase activity compared to control. It was concluded that CG and GA dipping delayed ripening and maintained quality of 'Hindi-Besennara' mangoes during 2 weeks of shelf life. PMID- 29184220 TI - Optimizing extraction conditions of crude fiber, phenolic compounds, flavonoids and antioxidant activity of date seed powder. AB - The objective of this study was to optimize the extraction conditions of crude fiber, phenolic compounds, flavonoids, and antioxidant activity from date seeds powder, using Response Surface Methodology. A central composite design with four independent variables; concentration of ethanol (X1 = 25, 50 and 75% v/v), solvent: sample ratio (X2 = 40:1, 50:1 and 60:1 v/w), temperature (X3 = 45, 55 and 65 degrees C), and extraction time (X4 = 1, 2 and 3 h) and a three level face centered cube design were used. A total of twenty nine experimental runs with five replicates at the central point were used to study the response variables using two extraction cycles. Maximum phenolic compound content (71.6 mg GAE/100 g) was extracted using 50% ethanol solution with 40:1 solvent: sample ratio for 1 h at 55 degrees C. While the maximum antioxidant activity (55.02 umol Fe(II)/g) was obtained using similar ethanol concentration and solvent: sample ratio except at lower temperature (45 degrees C) for 2 h. On other hand, the maximum flavonoids content (455.77 mg CEQ/100 g) was reached by using 50% concentration, 50:1 solvent: sample ratio at 65 degrees C for 3 h. In contrast, the content of fiber was not affected by the different extraction conditions. Results indicate that using combination of extracted conditions, have a great potential for extracting all depending compounds except crude fiber. PMID- 29184221 TI - Amino acid composition, antioxidant and functional properties of protein hydrolysates from Cucurbitaceae seeds. AB - In this study, the effect of enzymatic hydrolysis of globulin fraction of C. moschata (CMH), C. lanatus (CLH) and L. siceraria (LSH) on antioxidant capacity, functional properties, structural and micro-structural properties, as well as amino acid compositions were evaluated. All the hydrolysates exhibited significant antioxidant properties. The essential amino acids content in LSH (92.7 mg/g) was higher than CMH (79.9 mg/g) and CLH (70.5 mg/g). Water absorption capacity (5 g/g), heat stability (89%), emulsifying activity index (98.3 m2/g) and emulsifying stability index (45.1 min) were statistically more significant for LSH as compared to CMH and CLH. In addition, LSH had significantly higher FS and FC at pH 3-9. Among all hydrolysates, LSH showed highest solubility (87.3%) as compared to other hydrolysates. The results suggested that enzymatic hydrolysis improve the antioxidant and functional properties. Thus, the globulin hydrolysates might be served as an innovative source with promising nutritive values, good antioxidant and functional properties. Moreover, these could be used in food and pharmaceutical industries for the development of novel functional foods. PMID- 29184222 TI - Naturally occurring folates in selected traditionally prepared foods in Southern India. AB - A wide range of Indian foods (cereals, pulses, vegetables and milk based preparations) were analysed for five folate vitamers naturally present in the foods (n = 44). A liquid chromatography-mass spectrometry (LC-MS/MS) method using reversed phase chromatography and tandem mass spectrometry, coupled via positive mode electrospray ionization was used for the detection and quantification of the vitamers. The optimized LC-MS/MS method was capable of analysing the five most commonly-occurring folates (folic acid, 5-methyl tetrahydrofolic acid, tetrahydrofolic acid, 10-formyl folic acid and 5-formyl tetrahydrofolic acid) in 20 min. Quantification of folates was performed using 13C labelled internal standards. 5-methyl tetrahydrofolate was predominant in cereals, pulses and vegetable preparations. Fermented cereal preparations, beverages (coffee and tea) and green leafy vegetables were the main sources contributing to 5-formyl THF. Folic acid was identified in home-made yoghurt. All the values obtained in the present study using LC-MS/MS were compared to the total folate analysed using the microbiological assay in 2010 to generate data on the same foods. Findings suggest that the data obtained using both techniques showed agreement in the values (total folate calculated by adding the individual vitamers in the case of the LC-MS/MS values) particularly when foods were predominant in 5 methyl tetrahydrofolate. PMID- 29184223 TI - Properties of spray-dried fish oil with different carbohydrates as carriers. AB - This study evaluated the application of cashew gum, Arabic gum and starch on physical and thermal properties, and fatty acid profiles of spray-dried fish oil. A completely randomized design was used to evaluate the influence of the type of material on the properties of the microparticles. Hygroscopicity and solubility was higher for particles produced using cashew gum and reached 15 g/100 g and 85 g/100 g, respectively. Analyzing the thermogravimetric curves, it was found that cashew gum bulk showed two steps of degradation. For the microcapsules containing encapsulated fish oil in cashew gum, an extra degradation step at 471 degrees C was found. It was possible to verify the occurrence of diffused and wide peaks in the X-ray diffractograms for all three carbohydrate polymers. The particles produced presented spherical shape with cavities. The fatty acid profile for the fish oil changed only when using modified starch as wall material, where a significant loss of omega-3 fatty acids was observed. The particles produced with cashew gum had physical properties similar to those when applying materials commonly used and this biopolymer has the potential for application as a carrier in spray drying processes . PMID- 29184224 TI - Performance, carcass traits, meat quality and amino acid profile of different Japanese quails strains. AB - Poultry production is considered one of the prospective opportunities to accomplish sustainable and quick production of superior protein to challenge the growing mandate for animal protein. Therefore, this study was aimed to explore the difference on growth performance, carcass traits, meat quality and amino acid profile of different Japanese quails strains. A total of 480 quail chicks of four different plumage colors (120 of each white, golden, gray and brown) were collected after hatching. At 6 week of age, birds were stunned and decapitated to determine the physical meat quality, thiobarbituric acid reactive substances and amino acid profile. White quails had the highest weight of slaughter, carcass, dressing, carcass yield, liver, gizzard, heart and spleen (197.27 g, 169.27 g, 91%, 82%, 6.63 g, 6.53 g, 2.27 g and 0.40 g, respectively). Also, they had the highest PhU, lightness, yellowness and water holding capacity with the lowest level of redness, cooking losses and thiobarbituric acid in pectoral (6.28, 46.40, 12,46, 22.17, 9.20, 19.21 and 0.44, respectively) and thigh muscles (6.37, 42.30, 11.51, 26.01, 10.12 and 0.93, respectively). Moreover, they possessed the highest level of all essential (11.68 and 10.16 g/100 g protein in pectoral and thigh muscles, respectively) and non essential amino acids (13.27 and 12.54 g/100 g protein in pectoral and thigh muscles, respectively). Therefore, the current study revealed that white quails had the heaviest body weight with the best carcass traits and meat quality. PMID- 29184225 TI - Thermodynamic and kinetics study of phenolics degradation and color of yacon (Smallanthus sonchifolius) microparticles under accelerated storage conditions. AB - This study aimed to investigate the kinetics and thermodynamic of the phenolics degradation and the kinetics of degradation of the total color difference of yacon juice microcapsules produced by spray drying using Gum Arabic and polydextrose as wall materials. The degradation of the microcapsule was evaluated by accelerated tests under controlled conditions at 35 and 45 degrees C, and relative humidity of 75 and 90%, for 35 days. Degradation of phenolics followed the first order model and the degradation constant was in the range of 0.0124 0.0209 days-1. The microparticles with gum Arabic were more stable than those with polydextrose for all conditions studied, with longer half-lives. Both wall materials showed similar thermodynamic characteristics, indicating similar mechanism of degradation of phenolics. With respect to the color parameters, the first order model adjusted to data of the total color difference, and no significant differences were observed for the conditions studied. PMID- 29184226 TI - Antioxidant activity and protective effect of bee bread (honey and pollen) in aluminum-induced anemia, elevation of inflammatory makers and hepato-renal toxicity. AB - Aluminum toxicity might be related to oxidative stress, and the antioxidant activity and protective effect of bee bread, which contains pollen, honey and bees' enzymes, on aluminum induced blood and hepato-renal toxicity was investigated in rats. Chemical analysis and antioxidant capacity of bee bread were conducted. The animal experiment in rats included; group 1: received distilled water (10 ml/kg b.wt), group 2: received aluminum chloride (662.2 mg/kg b.wt), group 3: received aluminum chloride (662.2 mg/kg b.wt) and ethanolic extract of the bee bread (500 mg/kg b.wt), and group 4: received aluminum chloride (662.2 mg/kg b.wt) and ethanolic extract of the bee bread (750 mg/kg b.wt). Doses were given once daily via a gavage. C-reactive protein, transaminases, urea, creatinine, creatinine clearance, sodium and potassium and urine sodium and potassium were determined on day 28 of the experiment. Bee bread contained protein, fat, fiber, ash, carbohydrate, phenol and flavonoids and it exhibited antioxidant activity. Aluminum caused a significant elevation of blood urea, transaminase, C-reactive protein and monocyte count and significantly decreased hemoglobin. These changes were significantly ameliorated by the use of bee bread. Bee bread has an antioxidant property, and exhibited a protective effect on aluminum induced blood and hepato-renal toxicity and elevation of inflammatory markers C-reactive protein, leukocyte and monocyte counts. PMID- 29184227 TI - Construction of a lateral flow strip for detection of soymilk in milk. AB - A lateral flow based detection method for ascertaining the presence of soymilk in whole bovine milk has been described. The method uses commercially available rabbit anti-soy protein antibodies conjugated to gold nanoparticles (AuNPs) wherein soymilk protein in adulterated milk and soymilk protein at test line competes for limited antibodies. At control line, anti-rabbit immunoglobulin was immobilized for ensuring flow properties of antibody-conjugated AuNPs. Absence or diminished intensity of band at test line indicates presence of soymilk in milk. The soymilk detection limit was 1.75% (v/v) in whole bovine milk and results are available in 5 min. Constructed lateral flow device can be used for on-spot examination of soymilk in milk. PMID- 29184228 TI - Development of sweet and sour chicken meat spread based on sensory attributes: process optimization using response surface methodology. AB - Now a day's meat and meat products are not only generating convenience trends; they have been recognized as core of meat industry. Meat spread is a convenience cooked spreadable product prepared with meat and non-meat additives. Response surface methodology was used to investigate the effects of three different levels of honey (10, 15, 20 g), vinegar (2.0, 6.0, 10.0 ml) and tomato powder (0.5, 1.0, 1.5 g) on response variables viz. color/appearance, flavor, spreadability, texture, after taste, adhesiveability, overall acceptability, while standardizing the process of development of sweet and sour chicken meat spread box-behnken experimental design was used in which 17 different runs with 5 trials of three similar centre point. A second order polynomial was fitted to all the response variables and surface plots as well as equations were conducted. All the processing variables significantly affected the response variables either linearly or quadratically whereas the "Lack of Fit" was non-significant relative to the pure error. For optimization, target values were set in the form of ranges of all the processing and response variables. While applying multiple regression analysis, a total of 43 workable solutions was found, out of which the product with 14.28% honey, 5.38% vinegar and 1.39% tomato powder was selected. The responses for color/appearance, flavor, spreadability, texture, after taste, adhesiveability, overall acceptability, were predicted at 7.11, 6.72, 7.00, 6.99, 6.61, 6.94 and 6.79 respectively, with a desirability value of 1. PMID- 29184229 TI - Effect of soaking and germination on physicochemical and functional attributes of horsegram flour. AB - Horsegram is an underutilized pulse, traditionally used for treating various disorders like kidney stones, diabetes and joint pain. The present study was undertaken to optimize the soaking and germination conditions, to decrease the anti-nutritional factors and at the same time maintaining the nutritional properties of horsegram. Horsegram seeds were soaked for 6, 12 and 18 h followed by germination for 0, 24 and 48 h under different illumination conditions i.e., light and dark respectively. The soaked and germinated samples were dried in laboratory drier at 55 degrees C until constant moisture was achieved and was further analyzed for various quality attributes. Almost all the physicochemical and functional characteristics were significantly affected by both soaking and germination, whereas, germination done in light and dark conditions, exerted significant effect on the ascorbic acid content, total protein, total phenols, antioxidant activity and tannin content only. Based on the quality attributes, it was found that treatment having 18 h soaking and 48 h germination in the presence of light was the best where maximum decrease in the anti-nutritional factors was observed. Moreover, there was an increase in ascorbic acid, total protein content and a decrease in the anti-nutritional factors such as oxalate and tannin content. Thus, it is concluded that 18 h soaking and 48 h germination in the presence of light can be considered as the optimum conditions to increase the nutritional content of horsegram flour, which can further be utilized for the preparation of different value-added food products. PMID- 29184230 TI - Authentication of Romanian honeys based on physicochemical properties, texture and chemometric. AB - The purpose of this study was to investigate the physico-chemical properties (free acidity, pH, aw, ash content, moisture content, color (L*, a*, b*, hue angle, chroma and yellow index), fructose, glucose and sucrose content) and textural parameters (viscosity, hardness, adhesion, springiness, cohesiveness, chewiness and gumminess) of 50 samples of honey of different botanical origin (acacia, polyfloral, honeydew, sunflower and tilia). In order to achieve the authentication of the honey samples analyzed, their data have been subjected to linear discriminant analysis (LDA) and principal component analysis (PCA).The PCA and LDA have proved the possibility of honey authentication using the physico chemical and textural properties. LDA classified correctly 92.0% of the honeys based on their botanical origin, using the cross validation. In the LDA projection, the textural parameters (chewiness, hardness, cohesiveness, springiness) dominated the two functions. PMID- 29184231 TI - Transitions in mesocarp colour of mango fruits kept under variable temperatures. AB - The impact of variable temperatures on mesocarp colour development and physico chemical changes of mango fruits cv. Langra during ripening has been investigated. Physiological mature mango fruits were kept in temperature regulated chambers (20 and 25 degrees C) and at room temperature (29.8-33.6 degrees C). Progress in development of mesocarp colour, beta-carotene, sensory quality (SQ) and total soluble solids (TSS) content of fruits were analysed periodically from 48 to 168 h of ripening period. The progress of ripening period was accompanied by an overall increase in colorimetric value redness (a*), yellowness (b*), chroma or saturation (C*), a reduction in lightness (L*) and hue angle (h0) values. Colour development was found to be more in fruits ripened at higher temperatures than the fruits at lower temperature. beta-carotene content of pulp improved with ripening of fruits up to 120 h of ripening period. Fruits ripened at 25 degrees C recorded maximum sensory quality score. Pearson's correlation matrix studies revealed that fruit mesocarp colour a*, b*, C* values were directly correlated with beta-carotene, SQ and TSS with progress of ripening period. PMID- 29184232 TI - Antioxidant, functional properties and amino acid composition of pepsin-derived protein hydrolysates from whole tilapia waste as influenced by pre-processing ice storage. AB - In recent years, hygienic handling of fishery waste is demanded owing to the fact that the fishery waste is an ideal raw material for the preparation of bioactive compounds. In the present study, the effect of pre-processing storage (at 4 +/- 2 degrees C) of whole tilapia waste (WTW) on the properties of its protein hydrolysate derived using pepsin was evaluated. Fish protein hydrolysates (FPH) were prepared from 0, 24 and 48 h old ice stored WTW and designated as FPH-0, FPH 1, and FPH-2, respectively. Total amino acids, total essential amino acids and total hydrophobic amino acids of FPH samples increased with the storage period of raw material (WTW). Antioxidant activities such as DPPH (2, 2 diphynyl-1 picrylhydrazyl) free radical scavenging activity and ferric reducing power of FPH samples were dose dependent. FPH-0 had better antioxidant properties including linoleic acid peroxidation inhibition activity than FPH-1 and FPH-2. The DNA nicking assay revealed the protective effect of FPH preparations against Fenton's reaction mediated oxidative damage. FPH-2 had better emulsifying properties and foaming stability whereas the FPH-0 had relatively good foaming capacity. SDS PAGE indicated the presence of peptides ranging from 116 to < 14.4 kDa in FPH-0 and less than 18 kDa in FPH-1 and FPH-2. The present study, clearly demonstrated that whole tilapia waste can effectively be converted to FPH and could be a potential ingredient in functional food and as a rich source of high-quality protein in animal feed formulations. PMID- 29184234 TI - The effect of gamma irradiation on the properties of cucumber. AB - In this study, the effect of gamma irradiation on the shelf life and properties of cucumber was investigated. These properties include weight reduction, fruit density, juice, tissue firmness, total soluble solids (TSS), total titratable acidity, chlorophyll and vitamin C, pH, marketability, flavor, frostbite and fungal effects. For this purpose, cucumbers were irradiated with dose of 2, 2.5 and 3 kGy. The exposure time was calculated by MCNP4C; the Monte Carlo particle transport code. Three types of fungi (white-Sclerotinia sclerotiorum, gray Botrytis cinerea and olive-Cladosporium cucumerinum), were used to infect some samples. The chlorophyll and vitamin C preservation abilities were increased to about 3 and 1.4 times, respectively with irradiation treatment. Also, the shelf life was increased about 1 week, while chilling injuries is decreased. Samples' resistance to the fungal growth was evident and the process of fungal growth on the irradiated samples was delayed up to 1 week. The best properties were obtained at the irradiation dose of 2 kGy since it had less effect on flavor, TSS and tissue firmness.

The seeds contain a high percentage of protein (37.48%). However, little is known about the bioactive properties of these proteins and peptides, especially those generated by enzymatic hydrolysis. The objective of this study was to evaluate the biofunctional properties of total hydrolysates (TH) and peptide fractions from protein isolates of moringa seeds. Isoelectric protein isolates were prepared and TH were obtained by digestion with trypsin, chymotrypsin and pepsin-trypsin for 2.5 and 5 h. TH were fractioned by ultrafiltration (UF) with a 10 kDa membrane to generate the peptide fractions. In all treatments, the antioxidant capacity was significantly higher in peptide fractions > 10 kDa with 5 h of hydrolysis. The results showed that the fraction > 10 kDa of pepsin-trypsin digested for 5 h presented a better Angiotensin Converting Enzyme inhibition (ACE-I) activity with an IC50 of 0.224 MUg/MUl. Also, antidiabetic activity was enhanced in pepsin-trypsin treatment with 5 h of hydrolysis showing an IC50 of 0.123 MUg/MUl. Finally, this study showed that hydrolysates of moringa seed proteins had excellent in vitro nutraceutical potential.

AB - Nowadays, fingerprinting of food became one of the most perspective analytical tools to resolve a problem of food quality and authentication, especially in difficult cases like differentiation of fruit varieties. In this work, plum brandies distillated by the same technology from 25 plum cultivars were distinguished by comprehensive two-dimensional gas chromatographic analysis and sensory evaluation. The number of identified compounds in studied samples varied between 91 and 195 depending on the plum variety. Enriched volatile organic compounds (VOC) profile was identified for the samples received from "Chrudimer", "Cacak Fruitful" and "Hanita" plum varieties, whereas in the case of "Gabrovska", "Presenta", Elena" and "President" plum varieties, the VOC profile was significantly reduced. From qualitative point of view, the particular plum brandies showed differences in the presence of unsaturated fusel alcohols (e.g. 3 methyl-3-buten-1-ol, trans-3-hexenol), unsaturated aldehydes (2-butenal, 2 nonenal), monoterpene derivatives (e.g. linalool acetate, geraniol acetate) and lactones, which were mainly detected at the trace level.

AB - Prebiotic biomolecule, namely, inulin was extracted from Indian millets, namely, jowar (Sorghum vulgare), bajra (Pennisetum glaucum) and ragi (Eleusine coracana). Through qualitative assessment using Fourier Transform Infrared spectroscopy, the presence of functional groups of inulin in the above mentioned Indian millets were verified. The values of degree of polymerization of inulin derived from jowar, bajra and ragi were determined to be 27, 39 and 23 respectively. A comparative analysis of growth of Lactobacillus casei was carried out in presence of both lactose and inulin extracted from three millets and the commercial one. It was observed that the bajra inulin and lactose combination exhibited the best bacterial growth. The prebiotic effectiveness of different varieties of inulin was calculated to be in the following order: bajra > jowar > ragi > commercial inulin. Therefore the results on bajra inulin were highlighted in this article. Inulin yield from bajra was optimized as a function of temperature, HCl concentration and heating period. The maximum inulin yield (0.4727 g/g bajra) was obtained at temperature 70 degrees C, HCl concentration of 0.8 M and heating period of 60 min. The prebiotic activity score of bajra inulin (= 3.2) was measured to be much higher than commercial inulin (= 1.0). Growth dynamics of Lactobacillus casei on lactose, bajra inulin and mixture of lactose and bajra inulin were found to be of Monod type, Haldane type and Multi-substrate-summative type respectively. The techno-economic analysis based on the production cost of inulin from raw bajra seeds suggested that it was much cheaper than commercial inulin.

AB - This work was designed to obtain the valuable compounds with antioxidant, anti proliferative and anti-inflammatory activities from Astragalus chinensis. Ethyl acetate fraction obtained from A. chinensis L.f. had significant antioxidant, anti-proliferative and anti-inflammatory activities. Subsequently, five single compounds were separated and purified, which were identified as formononetin (1), rhamnocitrin (2), calycosin (3), beta-daucosterol (4), rhamnocitrin-3-O-beta-d glucoside (5). The results displayed that formononetin and rhamnocitrin exhibited significant cytotoxicity actions against tumor cell lines. Calycosin exerted the strongest anti-inflammatory effect of inhibition effects on NO production in macrophages.

AB - This study aimed to evaluate the effect of natural antioxidants in pork liver pate manufactured with the combination of pork backfat, fish oil and olive oil. Phenolic composition of beer residue extract (BRE), chestnut leaves extract (CLE) and peanut skin extract (PSE) were identified and quantified. Four batches of pork liver pate were produced: control, BRE, CLE and PSE. Pork liver pate was evaluated for proximate composition, pH, instrumental colour, free fatty acid content, lipid-derived volatile compounds and lipid oxidation. The major compounds of BRE were benzoic acid and catechin (1.79 and 1.51 mg/L, respectively), in CLE were ellagic and gallic acid (10.26 and 2.70 mg/100 g fresh weight) and in PSE was catechin (20.66 mg/100 g dry weight). Proximate composition was similar for all batches. The pH values were not influenced by any natural antioxidant. Colour parameters were affected by storage time but slight differences were observed among batches. Lipid stability (TBARS and lipid-derived volatile compounds) was not remarkably affected by addition of natural extracts. PMID- 29184239 TI - Effect of heating on oxidation stability and fatty acid composition of microwave roasted groundnut seed oil. AB - The oxidative stability and fatty acid composition of groundnut seed oil (GSO) exposed to microwaves were evaluated during heating at 170 degrees C. During heating, the oxidative indices such as free fatty acid, peroxide value, p anisidine value, TOTOX, thiobarbituric acid value, specific extinctions, and color value were increased. The increments were found to be higher in unroasted seed oils compared to roasted ones indicating lower release of lipid oxidation products in roasted GSO. After 9 h heating, the relative content of polyunsaturated fatty acid (PUFA) decreased to 89.53% and that of saturated fatty acid (SFA) increased to 117.46% in unroasted sample. The relative content of PUFA decreased to 92.05% and that of SFA increased to 105.76% in 7.5 min roasted sample after 9 h of heating. However, the roasting process slowed down the oxidative deterioration of PUFA. With increased heating times, an appreciable loss was more apparent in the triacylglycerol species OLL and OOL in unroasted samples compared to roasted ones. In FTIR, the peak intensities in unroasted samples were markedly changed in comparison with roasted samples during heating. The roasting of groundnut seed prior to the oil extraction reduced the oxidative degradation of oil samples; thereby increasing heat stability. PMID- 29184240 TI - Essential oils as antibacterial agents against food-borne pathogens: Are they really as useful as they are claimed to be? AB - Most studies evaluating the use of essential oils (EO) as antibacterial agents focus mainly on minimal inhibitory concentrations (MIC) rather than minimal bactericidal concentrations (MBC). In this work, we compared MICs and MBCs of EO from condiment plants commonly used in Mediterranean Europe, namely Origanum vulgare, Salvia lavandulaefolia, Salvia officinalis, Salvia sclarea and Rosmarinus officinalis, aiming to evaluate their application as disinfecting agents in minimally processed produce. Outbreaks-related pathogens such as Listeria monocytogenes, Pseudomonas aeruginosa and Yarrowia lipolytica were used. Results showed that all EO were able to reduce bacterial growth in all bacterial strains tested, particularly O. vulgare. However, fewer EO exhibited bactericidal activities, and were only effective against one or two bacterial strains, hence eliminating the possibility to use them as broad range disinfectants. Furthermore, the necessary concentrations were too high for food application. Hence, our work suggests the need to evaluate MBC rather than MIC and questions EO usefulness in controlling undesired microorganisms. Overall, and despite the large volume of data published on EO, results obtained were not very encouraging for a realistic application on produce and question the viability of EOs as disinfecting agents in food. PMID- 29184241 TI - Effect of different operating conditions in cloud point assisted extraction of thymol from Ajwain (Trachyspermum Ammi L.) seeds and recovery using solvent. AB - Cloud point assisted extraction of thymol from water extract of Ajwain (Trachyspermum Ammi L.) seeds has been reported. Effects of different operating conditions, i.e., concentration of surfactant, heating time and temperature in extraction efficiency were investigated. It was observed that maximum extraction efficiency of thymol was achieved with 30% (v/v) of SPAN 80 surfactant, 45 min of heating at 65 degrees C. Recovery of thymol from the surfactant complex was optimal at 1:3 coacervate phase to solvent (acetone) volume ratio. A semi empirical correlation was proposed at the optimum time to predict the concentration of surfactant and temperature required for a desired yield. PMID- 29184242 TI - Antioxidant capacity and identification of bioactive compounds of Myrtus communis L. extract obtained by ultrasound-assisted extraction. AB - Ultrasound-assisted extraction was used to investigate the polyphenolic compounds, particularly anthocyanins, present in myrtle alcoholic extracts. This type of extract is typical in the making of liqueurs obtained from herbs or plants, especially medicinal plants. The leaf extracts were found to contain flavonoids from the quercetin and myricetin families. Besides these, the berry extracts also showed the presence of anthocyanins, hydrolysable tannins and quinic acid. The antioxidant capacity was studied using the ORAC and TEAC methods and the polyphenol content was measured using the Folin-Ciocalteu method. The results showed that the values produced by the ORAC and TEAC methods were in agreement and that the antioxidant capacity correlated with the polyphenol content. The results showed that the leaf extracts exhibited higher antioxidant capacity than the berry extracts. The extraction method was easily implementable, and proved to be a swift method for obtaining bioactive compounds from vegetable matrices. PMID- 29184243 TI - Starch digestibility and glycemic index of Paranthas supplemented with Citrus maxima (Burm.) Merr. fruit segments. AB - The present investigation was undertaken to develop paranthas suiting diabetic population with added health benefits. Paranthas were prepared using fresh and dry segments of pomelo. The increase in the concentration of segments decreased the texture value from 1080 to 1022 g force (fresh segments) and 1005 to 870 g force (dry segments). Naringin along with other bioactive compounds were retained to a greater extent in Paranthas containing dry pomelo fruit segments. Paranthas prepared using 20% (fresh) and 5% (dry) were sensorily acceptable. The pomelo incorporated paranthas had higher levels of resistance starch fractions (12.94%) with low predicted glycemic index (49.89%) compared to control Paranthas at 5.54 and 58.64% respectively. The fortified paranthas with an considerable content of bioactive compounds and low glycemic index indicate the possibility of using it as a dietary supplement. Thus utilization of pomelo fortification helps in improving the nutritional and functional property of paranthas suiting diabetes as well as general population. PMID- 29184244 TI - Assessment of inhibitory factors on bioaccessibility of iron and zinc in pearl millet (Pennisetum glaucum (L.) R. Br.) cultivars. AB - The variations in iron and zinc bioaccessibility as influenced by inhibitory factors in 13 pearl millet cultivars were evaluated. The results indicated that iron and zinc contents ranged between 5.59-13.41 and 2.11-5.19 mg/100 g. Polyphenols, flavonoids and phytic acid were highest in GHB744 (781 mg/100 g), HHB223 (116 mg/100 g) and HHB226 (1.080 g/100 g) respectively. Insoluble fiber content range from 9.36 to 12.89 g/100 g. Iron and zinc bioaccessibility was the highest in local Anantapur (17.95%) and GHB744 (15.19%) cultivar with low phytic acid. HHB226 exhibited high beta-carotene and phytase activity. In this study, the cultivars with high iron and zinc content also possessed high inhibitory factors which affected bioaccessibility. However, the bioaccessibility of iron did not seem to depend on the phytic acid: iron ratio alone. Further, a trend was observed in cultivars with low iron: zinc ratio had increased iron bioaccessibility. On the contrary, phytic acid: zinc ratio appears to play a significant role in zinc bioaccessibility. Certain cultivars with high iron content also had high phytase activity and beta-carotene content which could be exploited for further technological treatments to enhance the bioaccessibility of iron and zinc. PMID- 29184245 TI - beta-Lactoglobulin microparticles obtained by high intensity ultrasound as a potential delivery system for bioactive peptide concentrate. AB - This work attempted to assess the effect of high intensity ultrasound (HIUS) upon development of bio-based delivery systems, from beta-lactoglobulin (beta-Lg) gelled microparticles, for encapsulation of a bioactive peptide concentrate (PepC). Solutions of 150 g L-1 of commercial beta-Lg and 30 g L-1 PepC, at various pH values (3.0, 4.0 and 5.5), were accordingly subjected to gelation for 30 min using a dry bath kept at 80 degrees C. The gelled systems were then exposed to HIUS at 0-4 degrees C, and the effect of processing time (2.5-20.0 min) was ascertained. Laser light scattering and confocal microscopy were used to characterize the particle size distribution, prior to and immediately after HIUS treatment. Gels obtained at pH 5.5 and 4.0 were harder than those obtained at pH 3.0. Ultrasound treatment of gels produced an important reduction in particle mean diameter as sonication time elapsed. Confocal microscopy indicated that application of HIUS led to almost round and monodispersed particles, at both pH 5.5 and 4.0. The peptide encapsulation efficiency was assessed by chromatography and accompanied by assay for bioactivity, after precipitation of the encapsulated material and analysis of the soluble peptides therein. PMID- 29184246 TI - Effect of desiccant system on thin layer drying kinetics of corn. AB - Drying is one of the most important post-harvest processes for reducing the moisture content of agricultural products and improving their performance has obvious benefits. Most dryers are convective type in which hot air is used for reduction of product moisture content. Effect of adding a desiccant unit to a re circulating convective dryer on thin layer drying kinetics of corn kernels is reported here. The influence of the desiccant unit, drying temperature and flow rate on drying time, moisture diffusivity coefficient and reactivation energy were investigated. The experiments were conducted at air temperatures of 50, 60 and 70 degrees C and flow rates of 1, 1.4 and 1.8 kg/min with and without the desiccant unit. Results showed that the use of the desiccant wheel decreased drying time by 9.75% and increased drying rate by 7.85%. Application of a Logarithmic model for fitting the data, while being simple, resulted in good statistical indexes (R2 and RMSE). Moisture diffusivity coefficient was obtained to be in the 3.47258 * 10-11 to 8.18826 * 10-11 m2/s range, while activation energy varied between 14.2931 and 17.6770 kJ/mol on the average. Therefore, utilization of the desiccant unit accelerates moisture extraction from corn samples. PMID- 29184247 TI - Effect of packaging types and storage conditions on quality aspects of dried Thunbergia laurifolia leaves and degradation kinetics of bioactive compounds. AB - Thunbergia laurifolia leaves were dried by freeze drying (FD) and microwave heat pump dehumidified air drying (MHPD). The dried leaves were stored in polypropylene (PP) or aluminum laminated pouches (ALP) at 15, 25 or 35 degrees C and 60% RH. The samples were held for 180 days to observe changes in moisture content, color, total phenolics, antioxidant activity, catechin and caffeic acid. In general, samples in PP had a greater increase in moisture. Total phenolics content and ferric-reducing antioxidant power values increased for 120 days, then decreased thereafter. After 180 days, both FD and MHPD samples packaged in ALP and stored at 15 degrees C had the greatest total phenolics, antioxidant activity and bioactive compounds amongst the storage conditions. The first-order equation best described degradation behavior of catechin and caffeic acid for both drying technologies investigated. PMID- 29184248 TI - Differential accumulation of beta-carotene and tissue specific expression of phytoene synthase (MaPsy) gene in banana (Musa sp) cultivars. AB - An experiment was conducted with twelve major Indian banana cultivars to investigate the molecular relationship between the differential accumulation of beta-carotene in peel and pulp of the banana fruit and carotenoid biosynthetic pathway genes. The high performance liquid chromatography showed that all banana cultivars accumulated two-three fold more beta-carotene in non-edible portion of the banana fruit. However, Nendran, a famous orange fleshed cultivar of South India, had high beta-carotene content (1362 ug/100 g) in edible pulp. The gene encoding Musa accuminata phytoene synthase (MaPsy) was successfully amplified using a pair of degenerate primers designed from Oncidium orchid. The deduced amino acid sequences shared a high level of identity to phytoene synthase gene from other plants. Gene expression analysis confirmed the presence of two isoforms (MaPsy1 and MaPsy2) of MaPsy gene in banana fruits. Presence of two isoforms of MaPsy gene in peel and one in pulp confirmed the differential accumulation of beta-carotene in banana fruits. However, Nendran accumulated more beta-carotene in edible pulp due to presence of both the isoforms of MaPsy gene. Thus, carotenoid accumulation is a tissue specific process strongly dependent on differential expression pattern of two isoforms of MaPsy gene in banana. PMID- 29184249 TI - Spray drying egg using either maltodextrin or nopal mucilage as stabilizer agents. AB - In this work, a comparative study between spray drying (SD) of fresh egg by either maltodextrin (MD) or nopal-mucilage (MN) as stabilizing vectors was made. The powders obtained were characterized for drying performance, moisture content, chemical proximate analysis, thermal analysis (TGA), chemical composition (FTIR), microscopy (SEM) and rheology (viscoelasticity and steady state simple shear viscosity). Infrared analysis showed that MN has the effect of a thickening agent rather than an encapsulating one. Results indicated that SD egg with MN produced a high thermal and mechanical stable product and rendered the highest drying performance, producing a more uniform and defined sphere-shaped morphology in comparison to egg SD either alone and with MD. PMID- 29184250 TI - Pecan walnut (Carya illinoinensis (Wangenh.) K. Koch) oil quality and phenolic compounds as affected by microwave and conventional roasting. AB - In this study, the effects of conventional and microwave roasting on phenolic compounds, free acidity, peroxide value, fatty acid composition and tocopherol content of pecan walnut kernel and oil was investigated. The oil content of pecan kernels was 73.78% for microwave oven roasted at 720 W and 73.56% for conventional oven roasted at 110 degrees C. The highest free fatty acid content (0.50%) and the lowest peroxide value (2.48 meq O2/kg) were observed during microwave roasting at 720 W. The fatty acid profiles and tocopherol contents of pecan kernel oils did not show significant differences compared to raw samples. Roasting process in microwave oven at 720 W caused the reduction of some phenolic compounds, while the content of gallic acid exhibited a significant increase. PMID- 29184251 TI - Changes in nutritional and physico-chemical properties of pearl millet (Pennisetum glaucum) Ex-Borno variety flour as a result of malting. AB - The effect of malting periods on the nutritional composition and physico-chemical properties of flour from pearl millet (Ex-Borno) variety was evaluated. Grains were steeped at 25 degrees C for 24 h and germinated for different durations (12, 24, 36, 48, 60, 72, 84 and 96 h) before kilning at 55 degrees C for 18 h. The kilned seeds were devegetated, milled, sieved and analysed for their proximate composition, amino acid composition, total phenolic content, functional and pasting properties. The carbohydrate, fat and total phenolic contents of the pearl millet flour samples decreased while protein content increased with increased malting periods. Leucine was the dominant amino acid in the flour and 48 h-malted flour had the highest total amino acid (6.72). Peak viscosity significantly decreased as the malting period increased. Solubility index, pasting temperature and phenolic content of the flours ranged from 5.13 to 17.24%, 69.05 to 89.5 degrees C and 130.20 to 169.90 mg/100 g, respectively. Malting offers a means of improving the nutritional profile of Ex-Borno pearl millet flour with an increased protein and fibre and reduced fat content. Malting also enhanced the functional and pasting properties of the flour. PMID- 29184252 TI - Development and characterization of couscous-like product using bulgur flour as by-product. AB - Couscous is produced traditionally by agglomeration of Triticum durum semolina with water. The aims of this study were: to produce couscous-like product by substitution of semolina with bulgur by-product (undersize bulgur); to find optimum quantity of bulgur flour and processing conditions. In order to determine the optimum processing parameters and recipes; 0, 25 and 50% of bulgur containing couscous-like samples were prepared. The color, yield, sensory properties, total phenol and flavonoid contents, bulk density, protein and ash content, texture properties were determined. Two different types of dryer e.g. packed bed and microwave were used. Optimum parameters were predicted as 50% of bulgur flour for packed bed (60 degrees C) and microwave (180 W) drying with 50% (w/w) of water according to yields, color (L*, a*, b*) values and sensory properties (color, odor, general appearance). For packed bed drying at 60 degrees C yields were 54.28 +/- 3.78, 47.70 +/- 1.73 and 52.57 +/- 7.04% for 0, 25 and 50% bulgur flour containing samples, respectively. Lightness (L*) values of couscous-like samples were decreased with increasing the quantity of bulgur flour after both drying processes. Results of sensory analysis revealed that couscous-like bulgur were more preferable for consumers. PMID- 29184253 TI - Malt sprout, an underused beer by-product with promising potential for the growth and dehydration of lactobacilli strains. AB - Malt sprout (MS), a by-product of the malt industry obtained by removing rootlets and sprouts from the seed of germinated barley (Hordeum vulgare L.), was used as culture, dehydration and storage medium of three strains of lactobacilli: Lactobacillus salivarius CM-CIDCA 1231B and CM-CIDCA 1232Y and Lactobacillus plantarum CIDCA 83114. The three strains were grown in MS and MS supplemented with 20% w/v fructo-oligosaccharides (MS FOS). Bacterial growth was determined by registering the decrease of pH and by plate counting. Comparable results with those of microorganisms grown in MRS (controls) were observed in terms of lag times, DeltapH and acidification rates. Furthermore, during fermentation, a significant increase of DP6 (FOS with degree of polymerization 6) was observed at expenses of inulin and DP7, probably indicating their hydrolysis. A concomitant decrease of DP3, sucrose and monosaccharides was also observed, as result of their bacterial consumption during growth. The presence of FOS in the fermented media protected microorganisms during freeze-drying and storage, as no decrease of culturability was observed after 60 days at 4 degrees C (> 108 CFU/mL). Using MS appears as an innovative strategy for the production of lactobacilli at large scale, supporting their use for the elaboration of functional foods containing prebiotics and probiotics. PMID- 29184254 TI - Characterization of probiotic potential of Bacillus species isolated from a traditional brine pickle. AB - Fermented foods are known for their potential as main source of probiotics. The present study aimed at investigating the probiotic properties of bacteria isolated from fermented mango pickle. Non-hemolytic fermenting microbiota isolated from mango pickle was screened in vitro for their basic probiotic properties such as acid tolerance, bile salt, lysozyme and salt tolerance. They were also tested for their beneficial characters like cholesterol removal, bacterial adhesion to hydrocarbons, auto-aggregation, antimicrobial activity, beta-galactosidase activity, exopolysaccharide production and adhesion to HT-29 cell line. Outputs of these parameters were subjected to principal component analysis (PCA) and these results were interpreted to select prospective bacterial isolates that can be used as potential probiotics. Out of eight isolates, PUFSTP35 (Bacillus licheniformis), PUFSTP38 (Bacillus amyloliquefaciens) and PUFSTP39 (Bacillus subtilis) showed similar trend to Weissella cibaria (MTCC 9814) that was used as a reference strain for profiling probiotic properties. B. licheniformis PUFSTP35 from fermented mango pickle appear to be the most potential candidate for use as a beneficial probiotic.

AB - This is a first kind of study on genotype diversity of starches of Moth Bean an underutilized pulse of India. Physicochemical properties like amylose content (7.8-21.4%), swelling power (11-13.5 g/g), solubility (5.9-9.0%) of starches were observed to differ significantly among the six moth bean starches. Swelling power of all the moth bean starches was observed to increase in the temperature range of 55-95 degrees C. Scanning electron microscopy indicated polyhedral, irregular shape of granule. X-ray diffraction studies indicated a 'C' type crystalline structure and the starches differed significantly in relative crystallinity (17 34%) which affected significantly retro gradation tendencies of the starches. Peak viscosity of starches varied significantly and ranged between 4580 and 5087 cP. Resistant starch content of starches also varied significantly among the cultivars and ranged between 57.3 and 75.6%.

AB - Blue purple maize grain loses a great amount of anthocyanins during the nixtamalization processing. The impact of the process factors on anthocyanins losses has not been studied in detail. The objectives of this work were to: (1) determine the step of the nixtamalization procedure where the greatest anthocyanin loss occurs and (2) study the effect of cooking time, alkali concentration, and sample size on anthocyanin losses (AL), and on the color of masa and tortilla from blue purple maize grain. Two cooking times were assayed (25 and 35 min), three alkali concentrations (0.5, 0.7, and 1.0% w/w), and two maize grain sample sizes (100 and 1000 g). Alkali concentration determines the time required to solubilize the maize grain pericarp, higher concentrations resulted in shorter maize grain pericarp solubilization times and this variable was related with AL. The greatest AL occurred during the grain cooking step, but an additional loss took place during the steeping of cooked grain. For the cooking time of 25 min, AL were of 38.3% during the cooking step, and 21.3% during the steeping of cooked grain. The cooking time had no effect (p > 0.05) on AL in masa and tortilla whereas alkali concentration and sample size significantly affected it. The greater the concentration and size, the higher the AL. The color of masa and tortilla were affected by cooking time and alkali concentration. Increasing alkali concentration during the nixtamalization procedure, reduced the brightness and chroma of masa and tortilla and made these products seem darker and dull. PMID- 29184257 TI - Optimization and characterization of high pressure homogenization produced chemically modified starch nanoparticles. AB - Chemically modified starch (RS4) nanoparticles were synthesized through homogenization and water-in-oil mini-emulsion cross-linking. Homogenization was optimized with regard to z-average diameter by using a three-factor-three-level Box-Behnken design. Homogenization pressure (X1), oil/water ratio (X2), and surfactant (X3) were selected as independent variables, whereas z-average diameter was considered as a dependent variable. The following optimum preparation conditions were obtained to achieve the minimum average size of these nanoparticles: 50 MPa homogenization pressure, 10:1 oil/water ratio, and 2 g surfactant amount, when the predicted z-average diameter was 303.6 nm. The physicochemical properties of these nanoparticles were also determined. Dynamic light scattering experiments revealed that RS4 nanoparticles measuring a PdI of 0.380 and an average size of approximately 300 nm, which was very close to the predicted z-average diameter (303.6 nm). The absolute value of zeta potential of RS4 nanoparticles (39.7 mV) was higher than RS4 (32.4 mV), with strengthened swelling power. X-ray diffraction results revealed that homogenization induced a disruption in crystalline structure of RS4 nanoparticles led to amorphous or low crystallinity. Results of stability analysis showed that RS4 nanosuspensions (particle size) had good stability at 30 degrees C over 24 h.

AB - In this work, an attempt is made to study the effect of mass on convective heat transfer coefficient (CHTC) for open sun drying (OSD) of groundnut (Arachis hypogaea L.). Experiments were conducted during the month of May, 2016 in the climatic condition of Rohtak, India (28 degrees 54'0"N 76 degrees 34'0"E). Groundnut samples of 130 and 198 g were dried under OSD condition till almost no variation in its mass was recorded. Hourly data of the mass evaporated, groundnut temperature, relative humidity and ambient temperature were recorded. The experimental data obtained were used to determine the constants 'C' and 'n' in the Nusselt number expression using linear regression method. CHTC increased with the increase in mass of groundnuts. The experimental errors in terms of percent uncertainty were found to vary from 44.29 to 48.77%.

AB - Hydatid disease (HD) is caused by Echinococcus granulosus and is endemic in many parts of the world. This parasitic tapeworm can produce cysts in almost every organ of the body, with the liver and lung being the most frequently targeted organs. Peritoneum, omentum, and mesentery are among these unusual locations, which can cause diagnostic challenge and treatment delay. This review provides information on the reported cases of the peritoneal, omental, and mesenteric hydatid cyst in the world during the last 20 years. During the last 20 years, there have been 49 published cases of hydatid cysts in the peritoneum, mesentery, and omentum. Among the reported cases in the English literature, the most common presenting symptom has been chronic abdominal pain and the method of primary diagnosis has been ELISA and ultrasonography. The best treatment modalities have been surgical excision, with and without adjuvant therapy, with albendazole and scolicidal agents. The published follow-up studies showed a low recurrence rate.

AB - Background: Pain alleviation and improvement of functional status are the main objectives in the treatment of osteoarthritis. Artemisia absinthium (AA) was used traditionally in reducing pain and inflammation. The aim of the present study was to compare the effects of topical formulations of AA and piroxicam gel (PG) among patients with knee osteoarthritis. Methods: In total, 90 outpatients aged 30-70 years with the diagnosis of primary osteoarthritis in at least one knee were enrolled in a randomized double-blind clinical trial. The patients referred to the Rheumatology Clinic at Shahid Beheshti Hospital in Hamadan province during 2012-2013. The patients were randomly assigned into three groups, 30 patients per group, and respectively received AA ointment (AAO) 3%, AA liniment (AAL) 3%, and PG; three times daily (TID) for 4 weeks. The patients were visited at baseline, week 4, and week 6. The effectiveness criteria were pain severity which was assessed with a 10-point visual analog scale (VAS), the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) for total pain score (WTPS), total physical function score (WTPFS), and total stiffness score (WTSS). Repeated measure ANOVA, paired t test and post hoc were used to compare variables. Statistical analysis was performed using the SPSS software, version 13.0 (SPSS Inc., Chicago, Illinois). Results: All groups had similar patient demographics. The administration of PG significantly improved all tested criteria with no recurrence after discontinuing the treatment protocol. AAO alleviated all tested factors except for WTSS. Alleviation was comparable to PG. AAL only reduced pain factors (VAS, WTPS) in week 4 with recurrence in week 6. Conclusion: Administration of Artemisia ointment may have beneficial effects in the treatment of osteoarthritis. Trial Registration Number: IRCT201202123109N3. PMID- 29184261 TI - Adherence to the CONSORT Statement in the Reporting of Randomized Controlled Trials on Pharmacological Interventions Published in Iranian Medical Journals. AB - Background: Among manuscripts submitted to biomedical journals, randomized controlled trials (RCTs) form the backbone of evidence-based medicine. Hence, their protocol should be designed rigorously and their results should be reported clearly. To improve the quality of RCT reporting, researchers developed the CONSORT Statement in 1996 and updated it in 2010. This study was designed to assess the quality of RCT reporting vis-a-vis adherence to CONSORT among articles published in Iranian medical journals (English, Persian, CONSORT-endorsing, and non-CONSORT-endorsing). Methods: In this cross-sectional study, all RCTs published in all Iranian medical journals from September 2012 to September 2013 were retrieved to evaluate their adherence to CONSORT. The journals' instructions for authors were also reviewed to find out whether or not they endorsed CONSORT. The CONSORT 2010 Checklist was used. Microsoft Excel 2007 was applied to analyze the data, and MedCalc was employed to compare the groups. Results: Totally, 492 pharmacological RCTs that met our inclusion criteria were identified. Twenty-five items were reported in fewer than 50% of the articles. The differences between the articles published in Persian and English language journals were statistically significant in 17 items. The differences between the articles published in the CONSORT-endorsing and non-CONSORT-endorsing journals were significant in 8 items. Conclusion: Our findings showed very weak adherence to CONSORT. Authors, reviewers, and editors should be trained to use standards expressed by the CONSORT Group in reporting RCTs. PMID- 29184262 TI - Cerebral Ischemia-Reperfusion Injuries in Vanadyl-Treated Diabetic Rats. AB - Background: Ischemic stroke recovery is poor in diabetic mellitus (DM). Vanadium compounds (vanadium) relieve DM signs, but their influences on cerebral ischemia/reperfusion injury (I/RI) are inconclusive. Herein, the intensity of I/RI was inspected in vanadium-treated DM rats. Methods: Rats made diabetic with a single intravenous dose of streptozocin (39 mg/kg). Normal and DM rats used water or vanadyl solution for 45 days. Under isoflurane anesthesia, right middle cerebral artery occlusion was performed for 60 minutes and 12 hours reperfusion. Ischemic rats were divided into untreated-control normal (ICN) and diabetic (ICD), vanadium-treated normal (IVTN) and diabetic (IVTD) groups (n=14 each). After neurological deficit score (NDS) test, the rats were sacrificed and their brain removed and stained with triphenyltetrazolium chloride (TTC) to measure cerebral infarct volume (CIV, mm3) or Evans blue extravasation (EBE, MUg/g wet tissue). Data analysis was performed using one-way ANOVA and Tukey's test (SPSS software, version 21.0) and P values <0.05 were considered statistically significant. Results: Blood glucose (BG, mg/dL) was similar in ICN and IVTN, elevated in IVTD and ICD (245+/-6 vs. 344+/-2, P<0.001). The increased CIV in ICN and IVTN was similar (48+/-2 and 34+/-5), very high in ICD but lower in IVTD (249+/-37 vs. 110+/-16, P<0.001). EBE was absent in non-lesioned hemispheres, similarly increased in lesioned hemispheres of ICN and IVTN (14+/-1 and 13+/-1). EBE in IVTD was significantly lower than ICD (21+/-2 vs. 33+/-5, P=0.01). Conclusion: I/RI was moderate in normoglycemia and did not change with vanadium. Hyperglycemia robustly intensified I/RI. Vanadium ameliorated hyperglycemia and reduced I/RI. Nonetheless, more investigations are required to link the mechanisms of vanadium on DM and stroke injuries. PMID- 29184263 TI - Antidiabetic and Antidyslipidemic Activities of the Aqueous Extract of Cochlospermum planchonii Leaves in Streptozotocin-Induced Diabetic Rats. AB - Background: Diabetes mellitus is considered one of the 5 principal causes of death in the world and is recognized as a global public health issue because of its multifactorial facets affecting essential biochemical processes in the body. This study investigated the antidiabetic and antidyslipidemic activities of the aqueous extract of Cochlospermum planchonii (C. planchonii) leaves in streptozotocin (STZ)-induced diabetic rats. Methods: Thirty adult female rats (Rattus norvegicus) weighing 153+/-3.41g were randomized into 6 groups of 5 animals each. STZ-induced diabetic rats were orally administered 50, 100, and 200 mg/kg body weight of the extract, respectively, once a day, and their blood glucose levels as well as variations of diabetes-associated biomarkers including alpha amylase, glucose-6-phosphate dehydrogenase (G6PDH), and lipid profile by the extract were monitored for 21 days. The results were expressed as means+/ SEMs and compared with repeated measures using SPSS, Data Editor, version 16.0. Results: The aqueous extract of C. planchonii leaves significantly reduced the blood glucose level in a dose-dependent manner, with the highest dose producing a 74.52% reduction after 21 days of administration, which compared significantly (P<0.01) with the control and metformin-treated groups. Similarly, STZ-induced diabetic mediated alterations in the serum lipids were significantly (P<0.01) restored by the extract. In addition, the aqueous extract of C. planchonii leaves significantly attenuated the decrease in the activity of G6PDH and the increase in the activity of alpha-AMY in the liver of the STZ-induced diabetic rats. Conclusions: Overall, the aqueous extract of C. planchonii leaves could be used to manage diabetes and other related complications. PMID- 29184264 TI - Effects of Subacute Administration of Co-Trimoxazole and Folic Acid on Ovarian Tissue in Adult Female Rats. AB - Background: Previous studies have reported the antifertility activities of sulfonamides. This study was designed to evaluate the effects of co-trimoxazole and its co-administration with folic acid on ovarian tissue in female rats. Methods: A total of 54 rats were randomly divided into 9 groups (n=6). Group I served as the control and group II (vehicle) received saline. Other groups, III to IX, received co-trimoxazole (30, 60, and 120 mg/kg; i.p.), folic acid (1 mg/kg; i.p.) or their combination for 14 days, respectively. The oocytes were obtained from each group at the end of the 14th days and scored for maturational status as germinal vesicle (GV), metaphase I (MI), or metaphase II (MII). The number of primordial follicle (PrF), primary follicle (PF), and secondary follicle in formalin-fixed ovaries were counted under light microscopy. The data were analyzed by one-way ANOVA followed by post-hoc Dunnet test using SPSS statistical software (version 17.0). Results were considered statistically significant at P<0.05. Results: Co-trimoxazole (60 and 120 mg/kg) treatment for 14 days caused a significant decrease in the number of GV (P=0.02, P<0.001), MI and MII (P=0.03, P<0.001), a significant increase in structural abnormalities, including PrF, PF and secondary follicle (P<0.001) as well as congestion, inflammation and necrosis of ovarian tissue compared to the vehicle group. Folic acid co-administration with co-trimoxazole reversed partially all these parameters compared to the co-trimoxazole group (P<0.001). Conclusion: The data showed the adverse effects of co-trimoxazole on the ovarian maturational status and tissue structure which was reversed partially by folic acid co-administration in rats. PMID- 29184265 TI - Long-term Low-Intensity Endurance Exercise along with Blood-Flow Restriction Improves Muscle Mass and Neuromuscular Junction Compartments in Old Rats. AB - Background: During the aging process, muscle atrophy and neuromuscular junction remodeling are inevitable. The present study aimed to clarify whether low intensity aerobic exercise along with limb blood-flow restriction (BFR) could improve aging-induced muscle atrophy and nicotinic acetylcholine receptors (nAChRs) at the neuromuscular junction. Methods: Forty-eight male Wistar rats, aged 23-24 months, were randomly divided into control, sham (Sh: subjected to surgery without BFR), BFR (subjected to BFR), exercise (Ex: subjected to 10 weeks of low-intensity exercise), Sh+Ex, and BFR+Ex groups. Forty-eight hours after the last training session, the animals were sacrificed and their soleus and extensor digitorum longus (EDL) muscles were removed. The hypertrophy index was calculated, and molecular parameters were measured using western blotting. Statistical analysis was done with ANOVA using SPSS (version 20), with a P<0.05 as the level of significance. Results: The control and Sh groups showed weight gain (P=0.001), whereas the Ex, Sh+Ex, and BFR+Ex groups had significant weight loss (P<0.001). The hypertrophy index of the soleus was significantly higher in the BFR+Ex group than in the control, Sh, and BFR groups (P<0.001). BFR+Ex induced significant hypertrophic effects on the EDL (P<0.001 vs. the control, Sh, Ex, and Sh+Ex groups, and P=0.006 vs. the BFR group). BFR+Ex also increased nAChRs in the soleus (P=0.02 vs. the control and Sh groups) and the EDL (P=0.008 vs. the control and Sh groups). Conclusion: BFR plus mild exercise is a safe method with potential beneficial effects in protecting and augmenting muscle mass and nAChR clustering at the neuromuscular junction in old rats. PMID- 29184266 TI - Effects of Saponin from Trigonella Foenum-Graecum Seeds on Dyslipidemia. AB - Background: Saponins identified from fenugreek (Trigonella foenum-graecum) seeds are reported effective on dyslipidemia. However, the definite mechanism is still not elucidated systematically. In this study, we evaluate the effects of saponin extract on cholesterol absorption, metabolism, synthesis, and reverse cholesterol transport in vivo. Methods: Saponin extract was prepared according to a craft established in our previous study. After the establishment of dyslipidemia model, 40 male Sprague-Dawley rats were divided into five groups, namely the control group (normal diet plus normal saline), HFD group (high fat diet plus normal saline), Lipitor group (high fat diet plus Lipitor (2 mg/kg)), and L, M, and H saponin groups (high fat diet plus saponin in dosages of 6, 12, and 24 mg/kg, respectively). Rats were sacrificed at the end of the 9th week after treatment. Biochemical characteristics of rats were tested, histopathological sections of liver tissue were observed, and the protein and mRNA expression of related factors of cholesterol in the intestine and liver were determined. One-way ANOVA test (SPSS software version 11.5, Chicago, IL, USA) was used to determine statistically significant differences between the HFD and other groups. Results: In saponin groups, the serum lipid, bile acid efflux, anti-peroxide activities, and lipid area of liver tissue improved. Cholesterol 7alpha-hydroxylase and scavenger receptor class B type I elevated in the liver. 3-hydroxy-3 methylglutaryl coenzyme A reductase levels were suppressed in both the serum and liver. However, significant cholesterol efflux was not found and Niemann-Pick C1 Like 1 levels elevated in the intestine. Conclusion: The mechanisms of saponin in Fenugreek effect on ameliorating dyslipidemia are probably related to accelerated cholesterol metabolism, inhibited cholesterol synthesis, and facilitated reverse cholesterol transport, but not cholesterol absorption. PMID- 29184267 TI - Deltamethrin-Induced Hepatotoxicity and Virgin Olive Oil Consumption: An Experimental Study. AB - Background: Deltamethrin (DM) is a synthetic pyrethroid insecticide which can lead to pathological effects in mammals through oxidative stress. On the other hand, virgin olive oil (VOO) is a rich source of phenolic compounds with antioxidants. The aim of the present study was to determine the protective effects of VOO against DM-induced hepatotoxicity. Methods: Thirty-six mice were randomly separated into 4 groups: vehicle group, VOO group, DM group, and DM plus VOO group. Immunohistochemistry of PARP, COX-2, and caspase-3 with the biochemical analysis of malondialdehyde and total antioxidant capacity levels were performed in the liver samples 5 weeks after gavaging. Statistical analysis was performed using SPSS, version 15. The data were compared between the groups using the Tukey multiple comparison tests and the analysis of the variance. A P value <0.05 was considered significant. Results: The malondialdehyde level in the liver was increased in the DM group (71.18+/-0.01), whereas it was significantly (P=0.001) decreased after VOO administration in the DM plus VOO group (39.59+/ 2.43). While the total antioxidant capacity level in the liver was decreased in the DM group (3.05+/-0.05), it was significantly increased (P=0.03) after VOO administration in the DM plus VOO group (3.95+/-0.04). A greater expression of caspase-3 (P=0.008), COX-2 (P =0.004), and PARP (P 0.006) could be detected in the DM group, while it was significantly (P=0.009) attenuated in the DM plus VOO group. Also, the degeneration of hepatocytes, which was detected in the DM group, was attenuated after VOO consumption. Conclusions: VOO exerted protective effects against DM-induced hepatotoxicity, which might be associated with its anti apoptotic, anti-inflammatory, and antioxidative properties. PMID- 29184268 TI - Impacts of Bone Marrow Stem Cells on Caspase-3 Levels after Spinal Cord Injury in Mice. AB - Spinal cord injury (SCI) is a drastic disability that leads to spinal cord impairment. This study sought to determine the effects of bone marrow stem cells (BMSCs) on caspase-3 levels after acute SCI in mice. Forty-two mice were randomly divided into 3 groups: control (2 subcategories), subjected to no intervention; sham (3 subcategories), subjected to acute SCI; and experimental (2 subcategories), subjected to SCI and cell transplantation. In the experimental group, 2*105 BMSCs were injected intravenously 1 day after SCI. The mesenchymal property of the cells was assessed. The animals in the 3 groups were sacrificed 1, 21, and 35 days after the induction of injury and caspase-3 levels were evaluated using a caspase-3 assay kit. The obtained values were analyzed with ANOVA and Tukey tests using GraphPad and SPSS. Based on the assessments, the transplanted cells were spindle-shaped and were negative for the hematopoietic markers of CD34 and CD45 and positive for the expression of the mesenchymal marker of CD90 and osteogenic induction. The caspase-3 levels showed a significant increase in the sham and experimental groups in comparison to the control group. One day after SCI, the caspase-3 level was significantly higher in the sham group (1.157+/-0.117) than in the other groups (P<0.000). Twenty-one days after SCI, the caspase-3 level was significantly lower in the experimental group than in the sham group (0.4+/-0.095 vs. 0.793+/-0.076; P?0.000). Thirty five days following SCI, the caspase-3 level was lower in the experimental group than in the sham group (0.223+/-0.027 vs. 0.643+/-0.058; P?0.000). We conclude that BMSC transplantation was able to downregulate the caspase-3 level after acute SCI, underscoring the role of caspase-3 as a marker for the assessment of treatment efficacy in acute SCI. PMID- 29184269 TI - Different Presentation of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery in Adults: Case Reports. AB - Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac malformation. We report three cases of ALCAPA who survived to adulthood. The first case was a 51-year-old woman who complained of typical chest pain that was diagnosed with ALCAPA using cardiac catheterization and coronary computed tomographic angiography (CTA). The second case was a 30 year-old woman with a history of surgery for atrial septal defect at 10 years old who presented with progressive exertional dyspnea. Cardiac catheterization confirmed the diagnosis of ALCAPA. The third case was a 19-year-old man who was brought to our clinic due to aborted sudden cardiac death on the previous day. Cardiac catheterization and coronary CTA confirmed the diagnosis. They underwent the closure of orifice of the anomalous left coronary artery and grafting the left anterior descending artery concomitantly with mitral valve repair. All patients were followed up during a mean of 8.7 months and they were asymptomatic. PMID- 29184270 TI - Recurrent Psammomatoid Juvenile Ossifying Fibroma with Aneurysmal Bone Cyst: An Unusual Case Presentation. AB - Juvenile ossifying fibroma (JOF) is a rare, benign, locally aggressive entity of the extragnathic craniofacial bones with a high tendency towards recurrence. Two distinctive microscopic patterns of juvenile ossifying fibroma have been described: a trabecular juvenile ossifying fibroma (TrJOF) and a psammomatoid juvenile ossifying fibroma (PJOF). Psammomatoid variant is predominantly a craniofacial lesion and occurs rarely in the jaws. The pathognomonic histopathologic feature is the presence of spherical ossicles, which are similar to psammoma bodies. Aneurysmal bone cyst exists as a secondary lesion arising from another osseous condition such as fibrous dysplasia, ossifying fibroma and giant cell granuloma. Very few cases of juvenile psammomatoid ossifying fibroma in association with the secondary aneurysmal bone cyst formation have been reported in the literature. Treatment consists of complete surgical removal; the incomplete excision has been associated with a high local recurrence rate. The authors report a case of recurrence of psammomatoid juvenile ossifying fibroma with aneurysmal bone cyst in an 8-year-old boy emphasizing the point that concomitant occurrence of these locally aggressive lesions requires adequate surgical removal and long-term follow-up. PMID- 29184271 TI - A Case of Cushing's Syndrome in Pregnancy. AB - Cushing's syndrome (CS) occurs rarely during pregnancy. CS can be caused by prolonged abnormal exposure to excess glucocorticoids leading to special and significant signs and symptoms. It is often difficult to diagnose pathological hypercortisolism in pregnant women since some symptoms of the disease might be due to a complicated pregnancy, including preeclampsia or gestational diabetes. In this study, we report the case of a 29-year-old female who referred to our institution with hypertension, weakness, steria, and truncal obesity. Physical examination revealed cushingoid characteristic. She was also found to be 27 weeks pregnant. CS was diagnosed on the basis of abnormal serum cortisol and adrenocorticotropin hormone (ACTH) levels, as well as radiologic findings. She eventually gave birth to a preterm infant via vaginal delivery. A right adrenal adenoma was diagnosed and was subsequently treated with surgical resection. The patient's condition remained stable after the surgery. PMID- 29184272 TI - Approach to Chronic Secondary Headache: A Case Report on Unusual Drug Side Effects. AB - In this article, we present the case of a 12-year-old female child who complained of bilateral temporal and frontal headache for 2 to 3 months with nausea and vomiting. Physical examination revealed right-sided sixth cranial nerve palsy and papilledema in ophthalmoscopy. To find the cause of increased intracranial pressure, the patient underwent brain imaging and brain MRI showed no abnormality. Ultimately, lumbar puncture (LP) was performed and cerebrospinal fluid (CSF) pressure was 280 mmH2O with normal chemistry. We considered pseudotumor cerebri as the first diagnosis. LP was carried out three times and 30cc of CSF was tapped each time. Finally, patient's headache and papilledema improved and physical examination after 6 months showed no sign of raised intracranial pressure (rICP). The most prominent point in her past medical history was the use of growth hormone (GH) for 2 years. No sign of symptom relapse has been seen after 6 months of drug discontinuation. We must consider the hazard of growth hormone as a potential cause of increased intracranial pressure. When the use of GH is justified, the follow-up must include an ophthalmoscopy examination in each session. PMID- 29184273 TI - Elderly-customized hatha yoga effects on the vascular inflammation factors of elderly women. AB - [Purpose] The aim of this study was to examine the effects of the application of elderly-customized hatha yoga on the vascular inflammation factors of elderly women. [Subjects and Methods] This research was conducted with 14 elderly women, between 70 and 80 years old, divided into an elderly-customized hatha yoga group (n=7) and a control group (n=7). The application group participated in a hatha yoga program designed to be elderly-friendly for 10 weeks. At the end of the program, the vascular inflammation factors were measured, including the albumin, white blood cell count, fibrinogen, high sensitivity C-reactive protein (hs-CRP), and erythrocyte sedimentation rate (ESR). [Results] In the hatha yoga group, the albumin increased significantly after the application, when compared to the level before the application, while the fibrinogen, hs-CRP, and ESR decreased significantly. In the control group, the vascular inflammation factor levels before and after the application period were not significantly different. [Conclusion] Based on the results of this study, the application of elderly customized hatha yoga created positive changes in the vascular inflammation factors of elderly women. PMID- 29184274 TI - The relationship between physical capacity and fear avoidance beliefs in patients with chronic low back pain. AB - [Purpose] The aim of this study was to investigate the relationship between physical capacity and fear avoidance beliefs in patients with chronic low back pain. [Subjects and Methods] This cross sectional study included 131 male university students with chronic low back pain. All the patients completed a fear avoidance beliefs questionnaire. Each participant performed a physical capacity test, which included hand grip force, leg strength, abdominal muscle endurance, flexibility, and cardiopulmonary endurance testing. [Results] Negative correlation was observed between physical capacity (leg strength, abdominal muscle endurance) and fear avoidance beliefs regarding work. Physical capacity (hand grip force, leg strength, cardiopulmonary endurance) showed a negative correlation with fear avoidance beliefs about physical activity. Abdominal muscle endurance and cardiopulmonary endurance were predictors of fear avoidance beliefs. [Conclusion] Physical capacity showed a negative correlation with fear avoidance beliefs in patients with chronic low back pain. The results of this study suggest that physical capacity is an important factor for predicting fear avoidance beliefs in patients with chronic low back pain. PMID- 29184275 TI - Effects of lower extremity injuries on aerobic exercise capacity, anaerobic power, and knee isokinetic muscular function in high school soccer players. AB - [Purpose] The study investigated the effects of lower extremity injuries on aerobic exercise capacity, anaerobic power, and knee isokinetic muscular function in high school soccer players. [Subjects and Methods] The study assessed U High School soccer players (n=40) in S area, South Korea, divided into 2 groups: a lower extremity injury group (n=16) comprising those with knee and ankle injuries and a control group (n=24) without injury. Aerobic exercise capacity, anaerobic power, and knee isokinetic muscular function were compared and analyzed. [Results] Regarding the aerobic exercise capacity test, significant differences were observed in maximal oxygen uptake and anaerobic threshold between both groups. For the anaerobic power test, no significant difference was observed in peak power and average power between the groups; however, a significant difference in fatigue index was noted. Regarding the knee isokinetic muscular test, no significant difference was noted in knee flexion, extension, and flexion/extension ratio between both groups. [Conclusion] Lower extremity injury was associated with reduced aerobic exercise capacity and a higher fatigue index with respect to anaerobic exercise capacity. Therefore, it seems necessary to establish post-injury training programs that improve aerobic and anaerobic exercise capacity for soccer players who experience lower extremity injury. PMID- 29184276 TI - Comparison of the effects of visual feedback training and unstable surface training on static and dynamic balance in patients with stroke. AB - [Purpose] This study compared the effects of visual feedback training and unstable surface training on the static and dynamic balance of stroke patients. [Subjects and Methods] The study enrolled 20 stroke patients and randomly assigned them to visual feedback training and unstable surface training groups. Both groups performed 30 minutes of conventional exercise therapy twice a week for 4 weeks. In addition, the subjects in the visual feedback training group completed a visual feedback training regimen and the subjects in the unstable surface training group completed training on an unstable surface (30-minute session three times a week for 4 weeks in both groups). Static and dynamic balance parameters were recorded immediately before and after the 4 weeks of training. For data analysis, the paired and independent t-test was used to compare the two groups. [Results] In the visual feedback training group, the sway line at the postural sway of the center of pressure and trace length decreased significantly after training. In both groups, the sway range at the limits of stability in the anteroposterior and mediolateral directions increased significantly after training. [Conclusion] Visual feedback training was better at improving static and dynamic balance than unstable surface training in stroke patients. PMID- 29184277 TI - Effect of axial shoulder external rotation exercise in side-lying using visual feedback on shoulder external rotators. AB - [Purpose] This study aimed to determine effectiveness of axial side-lying wiper exercise using the visual feedback with a laser pointer on infraspinatus and posterior deltoid muscles. [Subjects and Methods] The subjects were 22 healthy adults (18 males, 4 females) in their 20s who consented to participate in the present study. Surface Electromyography was used to measure the infraspinatus and posterior deltoid muscle activity before and after an intervention. The intervention consisted of performing side-lying wiper exercise with a 1-kg dumbbell and a ruled paper for 30 minutes. [Results] The infraspinatus illustrated significantly increased muscle activity after intervention. The posterior deltoid also showed increased activity after intervention but it was not significant. [Conclusion] Axial side-lying wiper exercise using the visual feedback has the therapeutic effectiveness for the selective infraspinatus muscle strengthening. Therefore it can be useful to provide shoulder movements with stability. PMID- 29184278 TI - Reliability of the test of gross motor development second edition (TGMD-2) for Kindergarten children in Myanmar. AB - [Purpose] The purpose of this study was to investigate reliability of the test of gross motor development second edition (TGMD-2) for Kindergarten children in Myanmar. [Subjects and Methods] Fifty healthy Kindergarten children (23 males, 27 females) whose parents/guardians had given written consent were participated. The subjects were explained and demonstrated all 12 gross motor skills of TGMD-2 before the assessment. Each subject individually performed two trials for each gross motor skill and the performance was video recorded. Three raters separately watched the video recordings and rated for inter-rater reliability. The second assessment was done one month later with 25 out of 50 subjects for test-rest reliability. The video recordings of 12 subjects were randomly selected from the first 50 recordings for intra-rater reliability six weeks after the first assessment. The agreement on the locomotor and object control raw scores and the gross motor quotient (GMQ) were calculated. [Results] The findings of all the reliability coefficients for the locomotor and object control raw scores and the GMQ were interpreted as good and excellent reliability. [Conclusion] The results represented that TGMD-2 is a highly reliable and appropriate assessment tool for assessing gross motor skill development of Kindergarten children in Myanmar. PMID- 29184279 TI - Relationship between gross motor function and the function, activity and participation components of the International Classification of Functioning in children with spastic cerebral palsy. AB - [Purpose] This study aimed to evaluate the relationship between gross motor function, measured using the Gross Motor Function Measure (GMFM), Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), and Functional Independence Measure for Children (WeeFIM), and Function, and Activity and Participation components of the International Classification of Functioning, Disability, and Health-Child and Youth Check List (ICF-CY) in children with spastic cerebral palsy (CP). [Subjects and Methods] Seventy-seven children with spastic CP participated in the study. The GMFM, GMFCS, MACS, and WeeFIM were administered in their entirety to patients without orthoses or mobility aids. The ICF-CY was used to evaluate the degree of disability and health. [Results] The score of the ICF component of Activity and Participation had a significantly strong correlation with the scores of GMFM, GMFCS, MACS, WeeFIM, and ICF component of Function. [Conclusion] When establishing a treatment plan for children with spastic CP, the children's physical abilities, and their limitation in activity, performance, and participation, which would be measured using the ICF-CY, should be taken into consideration. PMID- 29184280 TI - Change in hand dexterity and habitual gait speed reflects cognitive decline over time in healthy older adults: a longitudinal study. AB - [Purpose] There is a relationship between physical and cognitive functions; therefore, impairment of physical function would mean cognitive decline. This study aimed to investigate the association between change in physical and cognitive functions. [Subjects and Methods] Participants were 169 healthy community-dwelling older adults who attend the survey after three years from baseline (mean age, 72.4 +/- 4.8 years). Grip strength, one-leg standing balance, five-times-sit-to-stand test, timed up and go, 5-m habitual walk, and a peg moving task were used to evaluate physical performance. Five cognitive function tests were used to assess attention, memory, visuospatial function, verbal fluency, and reasoning. Cognitive function was defined as the cumulative score of these tests. [Results] At baseline, five-times-sit-to-stand test, timed up and go, and hand dexterity were independently associated with cognitive function. In longitudinal analyses, changes in habitual walking speed and hand dexterity were significantly associated with change in cognitive function. [Conclusion] Deterioration of specific physical function, such as hand dexterity and walking ability, may be associated with progression of cognitive decline. Decreasing extent of daily functions, such as hand dexterity and walking ability, can be useful indices to grasp changes in cognitive function. PMID- 29184281 TI - High-intensity laser therapy versus pulsed electromagnetic field in the treatment of primary dysmenorrhea. AB - [Purpose] To determine the efficacy of high intensity laser therapy (HILT) versus pulsed electromagnetic field (PEMF) in the treatment of primary dysmenorrhea. [Subjects and Methods] This was a randomized clinical trial that included 52 girls diagnosed with primary dysmenorrhea and who were assigned randomly into two groups of equal numbers. The treatment was three sessions every cycle for three consecutive cycles where group (A) included those participants treated with HILT 15 min/session and group (B) those who were treated with PEMF 30 min/session. All patients were evaluated before starting the treatment as well as after the end of treatment by present pain intensity scale and the prostaglandin level in blood and pain relief scale at the end of treatment for both groups. [Results] The results showed a significant decrease in the severity of pain, statistically significant decrease in prostaglandin level in blood, and a statistically significant pain alleviation in both groups. With comparison between both groups there was a statistically significant decrease in the severity of pain, significant decrease in the blood levels of PGF2alpha, in group (A) than group (B). [Conclusion] Both HILT and PEMF are effective in the treatment of primary dysmenorrhea with HILT being superior to PEMF.

AB - [Purpose] The purpose of this study was to determine the effect on local fat deposition and body weight of wearing a near-infrared light belt around the abdomen. [Subjects and Methods] Twenty-eight obese female subjects participated in this experiment. For measurement of body composition, an impedance-style body fat analyzer was used. The experimental group performed treadmill walking 3 times per week for 12 weeks while wearing an activated near-infrared belt around the abdomen. The near-infrared belt was composed of light-emitting diodes having wavelengths of 630 nm, 830 nm, 880 nm, and 956 nm. [Results] The analysis of abdominal circumference indicated that the abdominal circumference of the experimental group was reduced in post-test measurements compared to pre-test. [Conclusion] This investigation showed significant reductions in abdominal circumference, abdominal fat percentage, fat mass, and body-mass index for the experimental compared to the control group, suggesting that changes in body composition can be enhanced when near-infrared radiation is applied to the abdomen during walking. PMID- 29184284 TI - The effects of short-term lumbar stability cross taping on muscle strength of trunk extension and lumbar pain level in patients with chronic back. AB - [Purpose] The purpose of this study was to investigate the effects of short-term lumbar stability cross taping program on muscle strength of trunk extension and lumbar pain level in patients with chronic back pain. [Subjects and Methods] The present study divided 14 patients with chronic back pain into the stability cross taping group (SCTG; n=7) and the control group (CONG; n=7). Lumbar cross taping was applied to SCTG for 7 days, but the taping was not applied to CONG. After 7 days of the lumbar stability cross taping application to SCTG, lumbar muscle function and lumbar pain levels were measured using a Medx lumbar extension machine (Medx, USA) and a visual analogue scale (VAS) for the subjects in both SCTG and CONG. [Results] For SCTG, all the elements in lumbar muscle function and were significantly improved and lumbar pain level was also significantly reduced after the application of the 7-day lumbar stability cross taping. However, CONG did not show any statistically significant changes. [Conclusion] The results of the present study showed that the lumbar stability cross taping is an effective rehabilitation to improve lumbar muscle function and reduce lumbar pain level in patients with chronic back pain. PMID- 29184285 TI - Knee position sense: does the time interval at the target angle affect position accuracy? AB - [Purpose] This study examined whether the interval at the target angle during knee joint position sense (JPS) affected reposition accuracy, and evaluated the consequence of this factor on test-retest reliability. [Subjects and Methods] Twenty healthy subjects participated in this study. Reposition ability was measured after the knee was placed at a target angle (ranging from 40 degrees to 60 degrees ) for intervals of 3, 6, 9, and 12 seconds, in randomized order. Two trials were performed for each condition. The measurement was repeated after a week. The absolute error (AE) of each trial and average AE under each condition within the two measures were used for data analysis. [Results] No significant difference was found in comparing the AE or the average AE during all trials and between the two measures. Fair-to-good reliability was found for the AE results of all trials under the conditions of 3, 6, and 12 seconds. Poor reliability was found with time interval of 9 seconds. [Conclusion] The length of time needed to memorize the target angle during knee JPS test might affect test reliability. Practitioners can use this information when collecting JPS data. PMID- 29184286 TI - Test-retest reliability of linear and nonlinear measures of postural stability during visual deprivation in healthy subjects. AB - [Purpose] The purpose of this study is to evaluate the reliability of linear and nonlinear measures of the center of pressure (COP) during visual deprivation. [Subjects and Methods] Fifteen young adults participated in this study. COP signals were recorded in two conditions: eyes open and eyes closed. Three trials were performed in each condition with a rest period of approximately 1 min. The intraclass correlation coefficients (ICCs) and standard error of measurement (SEM) were calculated. [Results] The investigation of ICC and SEM between trials showed that the Lyapunov exponent (ICC: 0.76-0.96, SEM: 0.03) and total mean velocity (ICC: 0.71-0.95, SEM: 0.05) were more reliable and repeatable than range and area (95% confidence ellipse), while area had the least reliability (ICC: 0.49-0.77, SEM: 0.56). [Conclusion] The Lyapunov exponent can be considered an appropriate postural control index, and the evaluation of postural stability should be done by considering linear and nonlinear tools. PMID- 29184287 TI - Gross motor skill development of 5-year-old Kindergarten children in Myanmar. AB - [Purpose] The purpose of this study was to examine the gross motor skill development of 5-year-old Kindergarten children in Myanmar. [Subjects and Methods] Total 472 healthy Kindergarten children (237 males, 235 females) of 2016 2017 academic year from four schools in urban area and four schools in rural area of Myanmar were recruited. The gross motor skill development of all subjects was assessed with the test of gross motor development second edition (TGMD-2). All subjects performed two trials for each gross motor skill and the performance was video recorded and scored. The assessment procedures were done according to the standardized guidelines of TGMD-2. [Results] The majority of subjects had average level of gross motor skill rank. The significant differences were found on the run and gallop of locomotor skills and the most of object control skills except the catch between males and females. The significant differences were also found between subjects from urban and rural areas. [Conclusion] Gross motor skill development of 5-year-old Kindergarten children in Myanmar had gender-based and region-based differences on both locomotor and object control skills. This study added a valuable information to the establishment of a normative reference of Kindergarten aged children for future studies. PMID- 29184288 TI - A new model of skeletal muscle atrophy induced by immobilization using a hook-and loop fastener in mice. AB - [Purpose] To study muscle atrophy, the muscle atrophy model mice have been used frequently. In particular, cast immobilization is the most common method to induce muscle atrophy. However, it is time consuming and often causes adverse events including skin injury, edema, and necrosis. The present study, we developed a hook-and-loop fastener (Velcro) immobilization method as a new, simple, and less invasive approach to induce muscle atrophy. [Subjects and Methods] Mice were bandaged in the knee joint extension and ankle plantar extension position. Muscle atrophy was induced by either winding a cast or Velcro around the limb. [Results] According to weight and fiber size, Velcro immobilization induced equivalent muscle atrophy to cast immobilization. Velcro immobilization reduced significantly the time for the procedure and the frequency of adverse events. [Conclusion] Velcro immobilization can induce muscle atrophy comparable to cast immobilization, but in a shorter time and with less complications. Velcro immobilization may contribute to the study of disuse muscle atrophy in clinical practice of physical therapy using a mouse model. PMID- 29184289 TI - Proprioceptive change impairs balance control in older patients with low back pain. AB - [Purpose] This study aims to determine the specific proprioceptive control strategy used during postural balance in older patients with low back pain (LBP) and non-LBP (NLBP) and to assess whether this strategy is related to proprioceptive decline and LBP. [Subjects and Methods] Pressure displacement center was determined in 47 older persons with LBP and 64 older persons with NLBP during upright stance on a balance board without vision. Gastrocnemius (GS) and lumbar multifidus muscle (LM) vibratory stimulations of 60 and 240-Hz, respectively, were applied to evaluate the relative contributions of different proprioceptive signals (relative proprioceptive weighting ratio, RPW) used in postural control. Age, height, weight, back muscle strength, L1/2 and L4/5 lumbar multifidus cross section area ratio, skeletal muscle mass index, sagittal vertical axis, and Roland-Morris disability questionnaire (RDQ) were evaluated. [Results] Compared with older patients with NLBP, those with LBP showed a lower RPW 240-Hz, lower L4/5 lumbar multifidus cross-sectional area ratio, and a significantly higher age and RDQ. Logistic regression analysis showed that RPW 240-Hz and age were independently associated with LBP, after controlling for confounding factors. [Conclusion] Older patients with LBP decreased their reliance on GS (RPW 240-Hz) proprioceptive signals during balance control. PMID- 29184290 TI - Kinematic analysis of head, trunk, and pelvic motion during mirror therapy for stroke patients. AB - [Purpose] The purpose of this study was to investigate mirror therapy (MT) condition by analyzing kinematic parameters according to mirror size and angle. [Subjects and Methods] Three hemiparesis stroke patients and five healthy adults participated in this cross-sectional study. Kinematic parameters during the MT were collected over a total of 5 trials for each subject (3 mirror angles * 3 mirror sizes). Center of pressure (COP) excursion data was collected by force plate, and other kinematic parameters by infra-red cameras. [Results] The larger the size and smaller the angle, the overall dependent variables decreased in all participants. Particularly, when virtual reality reflection equipment (VRRE) was used, the value of the flexion and the lateral tilt was the closest to the midline compared to all other independent variables. Moreover, it showed tendency of moving towards the affected side. Based on the results, MT for stroke patients has a disadvantage of shifting weight and leaning towards the unaffected side during therapy. [Conclusion] Therefore, it seems to be more effective in terms of clinics to apply VRRE to make up for the weak parts and provide more elaborate visual feedback. PMID- 29184291 TI - The effects of task-oriented training on hand dexterity and strength in children with spastic hemiplegic cerebral palsy: a preliminary study. AB - [Purpose] The purpose of this study was to investigate the effects of task oriented training (TOT) on hand dexterity and strength in children with spastic hemiplegic cerebral palsy. [Subjects and Methods] Twelve children with spastic hemiplegic cerebral palsy were randomly assigned to either the TOT group (n=6) or the control group (n=6). In both groups, conventional occupational therapy was performed 40-min/day, 2 times a week, for 4 weeks. In the TOT group, TOT was additionally performed for 20 min, and the control group received usual care. The box and block test (BBT) was performed to assess hand dexterity. Hand strength was also assessed using hand dynamometer. [Results] After intervention, the TOT group showed a significant improvement of hand dexterity. In the control group, BBT and grip strength were not significantly improved after intervention. [Conclusion] In clinical settings, we suggest that TOT may be used as an intervention to improve hand dexterity in children with spastic hemiplegic cerebral palsy. PMID- 29184292 TI - Cardiopulmonary rehabilitation program impact on prognostic markers in selected patients with resting and exercise-induced ventilatory inefficiency: a clinical trial. AB - [Purpose] Ventilatory limitation is a common problem in patients with chronic heart failure and pulmonary hypertension. Excess ventilation may arise from augmented ventilatory drive, over activity of chemoreceptors and muscle ergoreceptors, or premature onset of lactic acidosis. Exertional dyspnea can cause limitations in the activities of daily living and as a result, reduced quality of life for these patients. The aim of the present study was to evaluate the effect of cardiopulmonary rehabilitation program on ventilatory efficiency for these patients. [Subjects and Methods] Twenty five patients with chronic heart failure and twenty five patients with pulmonary hypertension and only forty of them completed the study. The training program consisted of interval aerobic training program, based on the results of cardiopulmonary exercise testing. Training period was about five months. Outcomes were ventilatory equivalent for CO2, (VE/VCO2 at anaerobic threshold), VO2 at anaerobic threshold, VO2 max and peak work load. Echocardiography parameters were also measured; right ventricular systolic pressure for patients with pulmonary hypertension and ejection fraction for patients with chronic heart failure. [Results] Both groups showed an improvement in ventilation during exercise in favor of patients with pulmonary hypertension. VE/VCO2 decreased by 6.65 in pulmonary hypertension and by 2.9 in chronic heart failure. Right ventricular systolic pressure decreased by 12.05 mmHg in pulmonary hypertension and ejection fraction increased by 17.74% in chronic heart failure. [Conclusion] Physical therapy cardiopulmonary rehabilitation should be considered in managing patients with ventilatory limitation such as pulmonary hypertension and chronic heart failure.

[Conclusion] This study confirmed that JOE can be used to reduce aspiration in patients with dysphagia after stroke. PMID- 29184296 TI - Effects of mental practice combined with electromyogram-triggered electrical stimulation for upper extremity function in stroke patients. AB - [Purpose] To investigate the effect of mental practice combined with electromyogram-triggered electrical stimulation (MP-EMG ES) on the upper extremity of stroke patients. [Subjects and Methods] Participants were randomly assigned to experimental group or control group. The experimental group received MP-EMG ES plus conventional rehabilitation therapy for 5 days per week for 4 weeks. The control group received only conventional rehabilitation therapy. Outcome measure included the Fugl-Meyer Assessment (FMA) and Motor Activity Log (MAL). [Results] Experimental group showed more improved in the FMA, MAL-AOU, MAL QOM compared with the control group.

PMID- 29184297 TI - The relationship between non-affected forelimb exercise and recovery after focal cerebral ischemia in acute phase. AB - [Purpose] In the present study, we hypothesized that exercise of the nonaffected forelimb in the early poststroke phase would stimulate the intact hemisphere, thereby influencing the hemisphere of the infarcted side and improving the performance of the hemiplegic limb. [Subjects and Methods] Adult male Sprague Dawley rats (8-10 weeks of age, weighing 250-300 g, n=12) were used and randomly divided into 3 groups: nonaffected forelimb exercise for 3 days and treadmill exercise 7 days after ischemia (ETF, n=6), resting for 3 days and treadmill exercise 7 days after ischemia (ETN, n=6), and after ischemia 10 days resting group. To validate nerve growth factor (NGF), western blot analysis was performed. The results were analyzed using SPSS for Windows version 18.0. and expressed as mean +/- standard deviation (SD). [Results] Early treadmill exercise increased the expression of NGF protein level in both ETE and ETN groups. Comparing between the nonaffected forelimb exercise and infarct hemisphere in NGF protein expression, the ETE group showed higher increase of NGF protein level in right hemisphere than ETN group, but there was no statistical significance. [Conclusion] The early treadmill exercise increased NGF protein expression levels in both hemispheres and the nonaffected forelimb exercise in the early poststroke recovery phase could enhance neuronal recovery after focal ischemia in rat models. PMID- 29184298 TI - Changes in rounded shoulder posture and forward head posture according to exercise methods. AB - [Purpose] This study aimed to determine the effect of forward head posture improving exercises on rounded shoulder posture when employing the self-stretch exercise, the McKenzie exercise, and the Kendall exercise as intervention methods based on previous studies that reported negative effects of unbalanced posture and musculoskeletal problems on forward head posture and rounded shoulder posture. [Subjects and Methods] The selected 28 subjects were randomly assigned into the McKenzie exercise group (n=9), the self-stretch exercise group (n=10), and the Kendall exercise group (n=9). To compare the forward head posture, the craniovertebral angle was used. To measure the rounded shoulder posture, the scapular index was used. [Results] There were significant differences in the craniovertebral angle and scapular index within the groups and no significant differences between the groups. [Conclusion] The result of this study showed that all interventions increased the craniovertebral angle and the scapular index, which revealed that the applied exercises had a positive effect on forward head posture and rounded shoulder posture. PMID- 29184299 TI - Differences in maximal strength and endurance of the tongue according to region in healthy adults. AB - [Purpose] The purpose of this study was to identify differences in maximal strength and endurance of the tongue among healthy adults. [Subjects and Methods] A total of 60 healthy volunteers (30 men; 30 women; age range, 20-26 years) were recruited and evaluated for maximal strength and endurance of the anterior and posterior regions of the tongue using the Iowa Oral Performance Instrument. [Results] Tongue strength in the anterior region was greater than that in the posterior region. In contrast, tongue endurance in the posterior region was greater than that in the anterior region. [Conclusion] In conclusion, these results confirm that the anterior region of the tongue exhibits greater strength, whereas the posterior region exhibits greater endurance. PMID- 29184300 TI - Influence of pilates training on the quality of life of chronic stroke patients. AB - [Purpose] This study was to observe the influence of Pilates training on the quality of life in chronic stoke patients. [Subjects and Methods] Forty chronic stroke patients participated in this study. They were divided into same number of experimental group (EG) and control group (CG). EG participated in a 60-min Pilates training program, twice a week for 12 weeks, while the CG did not participate in any exercise-related activities for the duration and participating in general occupational therapy without any exercise-related activities. Then the MMSE-K was performed before and after Pilates training to observe the influence of Pilates training on the quality of life in chronic stroke patients. [Results] Statistically significant improvement in the physical, social, and psychological domains was found in EG after the training. No statistically significant difference was found in all three quality of life domains for the CG. EG experienced a statistically significant improvement in all quality of life domains compared with that of CG. [Conclusion] Therefore, participation in Pilates training was found to effectively improve the quality of life in stroke patients. Pilates training involves low and intermediate intensity resistance and repetition that match the patient's physical ability and can be a remedial exercise program that can improve physical ability and influence quality of life. PMID- 29184301 TI - Effects of cervical stretching and cranio-cervical flexion exercises on cervical muscle characteristics and posture of patients with cervicogenic headache. AB - [Purpose] The present study aimed to conduct a comparative analysis of changes in mechanical characteristics of cervical muscles and cervical posture in patients with cervicogenic headache following exercise program intervention in order to present effective treatment methods for such patients. [Subjects and Methods] A total of 30 patients with cervicogenic headache were recruited and 15 patients were allocated to cervical stretching exercise group and 15 to cervical stretching exercise and cranio-cervical flexion exercise group. After 3 weeks of exercise intervention, craniovertebral angle and tone (Hz) and stiffness (N/m) of the suboccipital and upper trapezius muscles were measured. [Results] After the exercise program intervention, a greater amount of change in tone of suboccipital and upper trapezius muscles was found in the experimental group, as compared to the control group, but the difference was not statistically significant. Greater amount of change in muscle stiffness and craniovertebral angle was found in the experimental group, as compared to the control group. [Conclusion] Findings of the present study showed that cranio-cervical exercise was an effective form of exercise for changing muscle characteristics and posture in patients with cervicogenic headache. Such findings will be helpful in providing effective treatments for patients with cervicogenic headache.

AB - [Purpose] The purpose of this study was to quantitatively analyze changes in muscle tone and stiffness in the posterior cervical region of individuals in a static prone position in a sling or on a plinth. [Subjects and Methods] Twenty four men in their 20s were divided into a sling group and a plinth group, and their changes in muscle tone and stiffness over time in the upper cervical region, lower cervical region, and upper trapezius muscles during a static prone position were measured. [Results] The sling group showed increases in the mean values of muscle tone and stiffness in the upper cervical region immediately after the suspension. In addition, this group exhibited statistically significant declines in the muscle tone and stiffness of the upper cervical region and a statistically significant decline in the muscle tone of the upper trapezius region. [Conclusion] The findings of this study suggest that for the treatment of the posterior upper cervical region after sling suspension in a static prone position, the time required to reduce the muscle tone and stiffness of this region should be taken into account. PMID- 29184303 TI - The influence of the vibration form roller exercise on the pains in the muscles around the hip joint and the joint performance. AB - [Purpose] The purpose of this study is to examine the influence of the vibration form-roller exercise on the pain in the hip joint and the joint performances. [Subjects and Methods] 30 adult patients were randomly sampled and divided into form-roller group (15) and the vibration form-roller group (15). The two groups were exposed to an exercise regimen of 3 sessions per week, over 4 weeks. Each session was composed of warming-up (5M), main exercises (20M), and five minutes of cool-down (5M).

PMID- 29184304 TI - Easy assessment tool for motor imagery ability in elementary scool students. AB - [Purpose] The final purpose of the present study was to propose easy and quick mental rotation task. Since subjects can easily understand mental rotation task that they have to do, the task is considered to be available in particular children. However, existing mental rotation task using specific software asked subjects more than ten trials per one pictured stimulus, meaning that relatively long time is required to accurately measure. Thus, children have difficulty to keep their attention during the existing task and to demonstrate their ability accurately. To address the purpose of the present study, the performance of mental rotation task using paper was investigated whether the performance has similar characteristics to an existing mental rotation task using specific software, in order to verify the usability of the task using paper. [Subjects and Methods] Sixty-three elementary school participants were asked to determine whether a rotating hand picture was left or right as quickly as possible and indicate it by writing a diagonal line on the paper. The total time required judgment of 16 pictures and the number of judgment errors were counted. [Results] The number of judgment errors increased with an increasing stimulus rotation angle. Also, the mental rotation time improved with age. [Conclusion] These results suggest that the performance of mental rotation using paper has the same characteristics as the existing method using specific software. Therefore, the mental rotation using paper would be practical method for subjects having difficulty to keep attention relatively long time, such as elementary school children. PMID- 29184305 TI - The effect of knee flexion angles and ground conditions on the muscle activation of the lower extremity in the squat position. AB - [Purpose] The purpose of this study is to research the most effective knee flexion angle and ground condition in the squat position. [Subjects and Methods] The subjects of this study were 15 female college students who were able to perform squat movements and who had never previously experienced surgery, orthopedic disease, or musculoskeletal impairment. This study was conducted to examine changes of muscle activation of low-extremity muscles at different knee flexion angles of 70 degrees , 90 degrees , and 100 degrees . Balance Pad (Aero Step, TOGU, Germany) was used as unstable ground. Surface electromyogram (4D-MT & EMD-11, Relive, Korea) was used for measuring muscle activation. Measured muscles were vastus medialis, biceps femoris, tibialis anterior, and gastrocnemius. Muscle activation was determined by the root mean square (RMS). [Results] There was a difference in muscle activation of the vastus medialis and tibialis anterior according to the change of the knee flexion angle with the stable ground. However, there was no difference in muscle activation of the lower extremity muscles according to the change of the knee flexion angle with the unstable ground. [Conclusion] These results suggest that changes in the angle of the knee flexion with the stable ground affect the muscle activation of the vastus medialis and tibialis anterior. It was found that as the joint angle increases, muscle activation also increases. However, ground condition does not affect muscle activation. PMID- 29184306 TI - No significant correlation between the intensity of static stretching and subject's perception of pain. AB - [Purpose] The purpose of this study was to determine whether the intensity of static stretching measured quantitatively is related to subjects' perception of pain. [Subjects and Methods] Sixty-eight participants were recruited. Static stretching was performed once for 30 seconds while maintaining the knee at 0 degrees flexion and was continued to the point where pain was recognized. The intensity of stretching exerted by the practitioner was quantitatively measured by using a handheld dynamometer (HHD). A subject's pain scaled on one's perception was measured by using the visual analog scale (VAS). [Results] No significant correlation was found between the intensity of stretching and the VAS score representing the subject's pain scaled on one's perception. In this study, the most frequent VAS score was 7, and the mean VAS score was 5.57 +/- 1.77. The stretching intensity measured by using a HHD ranged from 28.4 to 133.0 N (mean, 72.04 +/- 22.37 N). [Conclusion] This study showed that the intensity of stretching quantitatively measured by using HHD did not correlate with the degree of pain reported by the subjects. Therefore, subjective responses cannot guarantee a consistent application of intensity. PMID- 29184307 TI - Does transcutaneous electrical nerve stimulation (TENS) simultaneously combined with local heat and cold applications enhance pain relief compared with TENS alone in patients with knee osteoarthritis? AB - [Purpose] The purpose of this study was to investigate whether transcutaneous electrical nerve stimulation simultaneously combined with local heat and cold applications enhances pain relief compared with transcutaneous electrical nerve stimulation alone in patients with knee osteoarthritis. [Subjects and Methods] Fourty-five patients with knee osteoarthritis participated in this study. They were randomly assigned to the following three interventions: transcutaneous electrical nerve stimulation simultaneously combined with local heat using a hot pack; combined with local cold using a cold pack; and transcutaneous electrical nerve stimulation alone. In each intervention, the knee pain level during walking and standing up from a chair, as well as dynamic balance and gait ability were evaluated immediately before and after a single intervention using the visual analogue scale and the timed up & go test, respectively. [Results] A significant improvement in dynamic balance and gait ability was only observed immediately after transcutaneous electrical nerve stimulation simultaneously combined with local heat application, although the degree of pain relief during standing and walking were comparable among the three interventions. [Conclusion] These results suggest that transcutaneous electrical nerve stimulation simultaneously combined with local heat application can immediately improve not only knee pain during standing and walking but also dynamic balance and gait ability in patients with knee osteoarthritis. PMID- 29184308 TI - Intrarater reliability of measuring the patella position by ultrasonography in weight-bearing condition. AB - [Purpose] The aim of this study was to determine the intrarater reliability of using ultrasonography as a measurement tool to assess the patella position in a weight-bearing condition. [Subjects and Methods] Ten healthy adults participated in this study. Ultrasonography was used to assess the patella position during step down with the loading knee in flexion (0 degrees and 20 degrees ). The distance between the patella and lateral condyle was measured to represent the patella position on the condylar groove. Two measurements were obtained on the first day and the day after 1 week by the same investigator. [Results] Excellent intrarater reliability, ranging from 0.83 to 0.93, was shown in both conditions. Standard errors of the measurements were 0.5 mm in the straight knee and 0.7 mm in the knee flexion at 20 degrees . Minimal differences in knee flexion at 0 degrees and knee flexion at 20 degrees were 1.5 mm and 1.9 mm, respectively. [Conclusion] Ultrasonography is a reliable assessment tool for evaluating the positional changes of the patella in weight-bearing activities, and it can be easily used by practitioners in the clinical setting.

AB - Background: Health-care providers must be at the forefront of tobacco cessation to ensure a downward shift in tobacco use. Medical schools constitute an important site for education and cessation efforts. Health-care professionals play a substantial role in influencing patients' lifestyle choices including tobacco cessation. Objectives: To examine the association between the duration of stay in the medical colleges and the smoking behavior among the medical students in Karnataka, India. Materials and Methods: One government and four private medical colleges were selected using stratified random sampling technique for this cross-sectional study. Sample size was 3288 medical students. A pretested self-administered questionnaire was used to collect data. SPSS version 12.0 was used for data analysis. The statistical methods used were frequencies, proportions, and Chi-square test. Results: Mean age of the study participants was 20.68 +/- 2.05 years for males and 20.20 +/- 1.91 years for females. Number of smokers among medical students after joining medical college increased 2.7 times. The duration of stay in the medical colleges was positively associated with the smoking behavior (P < 0.0001) among medical students, and the increase in the number of smokers reached up to 259.6% during internship. Conclusion: Smoking among medical students increases along with their stay in medical college. PMID- 29184317 TI - Building Evidence for Coverage of Fully Vaccinated Children of 12-23 Months of Age across Districts of North India, 2015. AB - Context: Unprecedented low coverage (63%) of fully vaccinated (FV) children in the recent round of national survey district level household (HH) and facility survey 4 (DLHS-4) propelled health system of Himachal Pradesh for an independent rapid assessment of FV coverage. Aim: The aim of the study was to assess the FV coverage among 12-23-month old children in the state. Settings and Design: A community-based survey with an interviewer-administered questionnaire was carried out in all 12 districts of Himachal Pradesh from September 2015 to January 2016. Subject and Methods: WHO 30 * 7 cluster technique was used. Statistical Analysis Used: Chi-square and unpaired Student's t-test along with 95% confidence intervals. Results: A total of 2492 children across 35,551 HHs (2.4% of state share) were surveyed with FV coverage of 98.1% (95% confidence interval [CI]: 97.5-98.6) and 86% (95% CI: 84.6-87.3) based on history and card, respectively. Conclusions: The reported FV coverage in the current study was observed too high in the state as reported in earlier round of the national surveys (except DLHS 4). PMID- 29184318 TI - Linkages between Hypertension and Coronary Heart Disease in India: Evidence from India Human Development Survey-2 (2011-2012). AB - Background: Cardiovascular diseases (CVDs) are the leading causes of death globally (nearly 17.5 million deaths/year). Hypertension and coronary heart disease (CHD) are two of the most important CVDs. There is a dearth of studies at a large scale in India to ascertain the factors as well as social differentials in the prevalence of heart disease associated with hypertension. This paper attempts to bridge the gap in the relevant area. Methodology: Secondary analysis of the data obtained from India Human Development Survey (IHDS), conducted in two rounds in 2004-2005 and 2011-2012, was done (n = 147,201). Bivariate and logistic regression analyses have been used. Results: In India, the prevalence for CHD is 1.1% for 2011-2012. Findings showed that persons with hypertension are 11 times (odds ratio [OR] = 11.58, P < 0.01) more likely to be affected by CHD among adults (15 and above years) as compared to nonhypertensive adults. When the odds are adjusted for socioeconomic and demographic variables, hypertensives are found to be 5 times more likely (OR = 5.096, P < 0.01) to be having CHD as compared to nonhypertensives. Conclusions: The unadjusted odds of suffering from CHD when hypertension is a predictor are much higher than when the odds are adjusted for socioeconomic and demographic variables. Along with hypertension, age, education, and place of residence have also been found to be important determinants of CHD. PMID- 29184319 TI - A Comparative Study of Depression and Associated Risk Factors among Elderly Inmates of Old Age Homes and Community of Rajkot: A Gujarati Version of the Geriatric Depression Scale-Short Form (GDS-G). AB - Background: The prevalence of depression among elderly people varies across different setups such as old age homes (OAHs), community, and medical clinics. Aims: The aim of this study was to compare the epidemiological factors pertaining to depression among elderly residents of OAHs and community, using a new Gujarati version of the Geriatric Depression Scale-Short Form (GDS-G). Settings and Design: A cross-sectional, epidemiological study conducted in an urban setup of Western India. Materials and Methods: All the eligible 88 elderly residents of all the six OAHs and 180 elderly residents from the same city were administered a pretested semistructured questionnaire having the GDS-G form. Statistical Analysis: Descriptive statistics, odds ratio, Spearman's rank correlation test. Results: The elderly of OAHs were more depressed compared to those of community (odds ratio = 1.84; 95% confidence interval = 1.09-3.06). Older age, females, weaker family ties, economic maladies, poorer self-perception of health status, presence of chronic ailments, absence of recreational activity, lack of prayers, impaired sleep, history of addiction emerged as the predictors of depression in both the setups. More health complaints and a later self-perception of visit to a doctor were found among the depressed than the nondepressed in both the setups. Conclusions: Depressive symptoms were quite high among the elderly in both the setups. Special attention should be given toward health checkups of depressed persons in the OAH and improvement of family ties among depressed persons of the community. PMID- 29184320 TI - Neck Circumference: Independent Predictor for Overweight and Obesity in Adult Population. AB - Background: Neck circumference (NC) measurement, an index of upper body fat (BF) distribution, seems promising as a community-based screening measure for overweight and obesity in want of evidence on its validity as a screener. Objective: The objective of this study was to determine the validity of NC as a screener for overweight and obesity in adults in community settings against BF percentage (BF%). Materials and Methods: This cross-sectional community-based study involved data collection on a predesigned, pretested, and semi-structured schedule that included the sociodemographic characteristics and anthropometric measurements of respondents. Results: NC correlated positively with body weight, waist circumference, and hip circumference. NC was found to have good discriminatory power with cutoff values of 36.55 cm for males and 34.05 cm for females, with maximum sensitivity and specificity to predict overweight and obesity in comparison to direct BF% estimation on receiver operating characteristic analysis. Conclusion: NC has a fair validity as a community-based screener for overweight and obese individuals in the study context. Further studies may be carried out to explore the generalizability of this observation. PMID- 29184321 TI - Rapid Response to Syphilis Outbreak among Female Sex Workers. AB - Background: Outbreak of syphilis, i.e., 16 cases of rapid plasma reagin (RPR) reactive cases of syphilis was reported in Community Based Organization (CBO) Sahyog of Surat, India, from April to August 2014. The aim of the study was to find risk factors and take immediate actions to prevent spread. Materials and Methods: Outbreak investigation of 16 Female Sex Workers of CBO Sahyog in Surat who were found Rapid Plasma Reagin (RPR) and Treponema Pallidum Hemagglutination Assay (TPHA) positive from April to August 2014; was carried out. Clinico epidemiological and laboratory-based evidence for different sexually transmitted infections (STIs) conducted at Government Medical College, New Civil Hospital, Surat. Root cause analysis (RCA) of index case was carried out. Results: Desk review for the past 3 years data of STI revealed total STI cases as 88 (2011), 95 (2012), and 130 (2013), of which 4, 2, and 2 found RPR reactive, respectively. Data from April to August 2014 revealed 16 RPR reactive cases and confirmed by TPHA. On examination, one had ulcerative cervical lesion, rest did not have any symptoms of syphilis. Eleven had vaginal/cervical discharge, 11 had lower abdominal pain. A total of 11 had unprotected sex, 7 encountered condom tear in the past 6 months, and 5 reported sexual violence. Seven had sexual activity under influence of alcohol. Laboratory investigation revealed two as HIV positive. RPR reactivity reported highest (9 out of 16) from same area of hotspot. RCA of probable index case revealed factors responsible as violence and nonuse of condoms. Conclusions: Outbreak investigation revealed one probable index case. All 16 treated with injection Penidure. Violence or condom tear is responsible for the spread. Crisis management team should be strengthened. PMID- 29184322 TI - Situational Analysis of Sickle Cell Disease in Gujarat, India. AB - Background: Sickle cell disease (SCD) is a major public health concern in tribal community not only in Gujarat but also globally. Gujarat, a western state of India, has 89.12 lakh tribal populations and is expected to have at least 9,00,000 sickle cell trait and 70,000 SCD patients. The aim of the present review is to document the prevalence of SCD in various communities and various screening methods adapted. Methodology: An in-depth literature review was carried out using available search engines such as Cochrane Library, PubMed, Scopus etc. and published articles, and government reports/policy documents with reference to SCD were gathered. Results: A total of 17 original research articles and 2 policy/program documents are included in this review. The review suggests a prevalence of 0.6%-35% studies conducted among medical students, tribal schoolchildren, and tribal adolescents, with diverse screening methodologies. Conclusion: A diverse prevalence is observed in this review. Various screening methods such as dithionite turbidity test/hemoglobin/high-performance liquid chromatography methods were used to estimate the prevalence, citing the need for standardization. It was also found that not only tribal population, but also nontribal population have the risk of getting SCD that needs to be further investigated properly. Qualitative studies with SCD patients are required to understand the quality of life and morbidity pattern. PMID- 29184323 TI - Stress and Stressors among Medical Undergraduate Students: A Cross-sectional Study in a Private Medical College in Tamil Nadu. AB - Background: Medical education is perceived as being stressful, and a high level of stress may have a negative effect on cognitive functioning and learning of students in a medical school. Objectives: To (a) assess the perceived stress among medical undergraduate students, (b) identify the sources of stress, and (c) find an association of perceived stress with sociodemographic characteristics and various stressors. Materials and Methods: A cross-sectional study was conducted among medical undergraduate students in a private medical college in Tamil Nadu. A total of 750 medical students from 1st year to final year were invited to participate in the study. Self-administered questionnaire was used to collect data regarding sociodemographic profile, perceived stress using perceived stress scale-14 and academic, psychosocial and environmental stressors. Descriptive statistics was used to describe the sociodemographic characteristics, sources of stress and perceived stress. Logistic regression analyses were carried out to assess determinants of stress. Results: The overall response rate was 93.33% (700 out of 750 students). The mean perceived stress score was 25.64 +/- 5.44. Higher age-group, year of studying bachelor of medicine and bachelor of surgery, vastness of academic curriculum, fear of poor performance in examination, lack of recreation, loneliness, family problem, and accommodation away from home were important determinants of perceived stress. Conclusions: The perceived stress was higher among higher age group and final year medical students. Academic, psychosocial, and environmental stressors are associated with perceived stress. Reframing the academic curriculum and examination patterns, incorporating recreational and sports activities, and establishment of counseling cells in the institution is needed. PMID- 29184324 TI - Status of Iodine Nutrition among Pregnant Women Attending Antenatal Clinic of a Secondary Care Hospital: A Cross-sectional Study from Northern India. AB - Background: Daily requirement of iodine increases during pregnancy making pregnant women a high-risk group for iodine deficiency disorders. The limited available literature shows that even in iodine sufficient population, pregnant women are iodine deficient. Objective: The objective of this study is to assess the current iodine nutrition status among pregnant women in Ballabgarh, district Faridabad, Haryana. Materials and Methods: Pregnant women were recruited from antenatal clinic (ANC) of subdistrict hospital (SDH), Ballabgarh, Haryana. Consecutive sampling strategy was followed to recruit pregnant women, and women of all trimesters were included in the study. Urinary iodine estimation was done using simple microplate method, and salt iodine was estimated using iodometric titration. The study was approved by Institute Ethics Committee, All India Institute of Medical Sciences (AIIMS), New Delhi. Results: Out of the total 1031 pregnant women, 90.9% were using adequately iodized salt. Median (interquartile range [IQR]) salt consumption by the pregnant women was 8.3 (6.7, 11.1) g/day. Median (IQR) urinary iodine concentration (UIC) for the pregnant women was 260 (199, 323) MUg/L. Only 13.5% of pregnant women had insufficient iodine intake (UIC <150 MUg/L). There was no significant difference in median UIC values by household salt iodine content and across three trimesters of pregnancy. Conclusion: Iodine nutrition status of the pregnant women attending ANC clinic of SDH Ballabgarh was adequate with attainment of universal salt iodization goal of >90% adequately iodized salt coverage in the study population. PMID- 29184325 TI - A Longitudinal Study to Assess the Role of Sanitary Inspections in Improving the Hygiene and Food Safety of Eating Establishments in a Tertiary Care Hospital of North India. AB - Introduction: Food safety inspections serve two purposes; determine compliance with the law and gather evidence for enforcement if there is noncompliance. The present study was conducted to assess the role of regular inspections on food safety in hospital premises. Methodology: This was an intervention based before and after study. A tool was prepared based on the Food Safety and Standards Regulations (FSSR) (in India) 2011. This included major, critical, and highly critical domains. Each item in the tool scored between 1 and 3 (poor, satisfactory, and good). Based on this, each eating establishment (EE) was given a score on conformance to FSSR 2011. Monthly inspection was made over a year and corrective actions were suggested. Results: The minimum preintervention score was (41.28%), and maximum was (77.25%). There was no significant association between type of meal services and score EE (P > 0.05). Higher proportion of EEs within the hospital building had a satisfactory and good score as compared to EEs outside the hospital building but within hospital premises (P < 0.05). Postintervention, there was a significant change (increase) in the scores of EEs. There was a significant increase in mean scores of EEs under major domains namely maintenance, layout of equipment, monitoring an detection, and elimination of food sources to the pests. Under critical and highly critical domains personal cleanliness, training, and self-inspection by food business operators improved significantly. Conclusion: Regular inspections can improve the food safety standards in EEs. PMID- 29184326 TI - Mapping Neonatal Mortality in India: A Closer Look. AB - Introduction: Fifty-three percent of Indian under-5 deaths occur during the neonatal age group. Recognizing that there is a lack of illustrated district level data on neonatal mortality in India, we mapped this to visually highlight districts where neonatal health issues require the most attention. Methods: District-level estimates of 596 Indian districts were used to generate maps and to illustrate neonatal mortality rates (NMRs), absolute numbers of neonatal deaths; the best and worst performing districts (positive and negative deviants) in each Indian state; the neonatal female/male death ratio; and district lag in NMR reductions. Results: The NMR ranged from 4.3 (Kannur, Kerala) to 65.1 (Datia, Madhya Pradesh), with the mean NMR being 29.8. Almost two-thirds of the districts (n = 380, 63.7%) had NMRs between 20 and 40. The top third of neonatal deaths could be accounted for by just 71 districts of a total of 596. Conclusion: There is an urgent need for up-to-date data on district-level neonatal mortality in India.

AB - Background: Pretreatment loss to follow-up (PTLFU) is used as performance indicator of Revised National Tuberculosis Control Programme (RNTCP) of India. Objective: To document the PTLFU, identify additional indicators and examine documentation of all the diagnosed sputum positive pulmonary tuberculosis (PTB) patients under RNTCP. Methodology: Tuberculosis (TB) laboratory, referral for treatment registers, and referral forms were perused for information on sputum positive PTB patients diagnosed from January to June 2014, in 3 TB Units in Chennai. Results: PTLFU was 24% (572 out of 2361). However, in pursuance with the principle of ensuring that all diagnosed patients must be started on treatment following referral, it was inflated to 44% (1046 out of 2361). Conclusion: The existing PTLFU indicator does not reflect the proportion of treatment initiation of all diagnosed smear-positive PTB patients. We propose additional indicators for monitoring referral and treatment initiation of all diagnosed sputum positive PTB patients.

PMID- 29184334 TI - Efficacy and Safety of Tacrolimus in Myasthenia Gravis: A Systematic Review and Meta-analysis. AB - Aims: This study was designed to determine whether treatments with tacrolimus would provide benefit for patients with myasthenia gravis (MG). Materials and Methods: The databases of Medline, EMBASE, the Cochrane Library, and four Chinese databases were searched for eligible studies. Weighted mean differences and standardized mean differences (SMD) with corresponding 95% confidence intervals (CIs) were used to summarize the primary outcome, namely, steroid-sparing effect of tacrolimus in maintaining minimal manifestations, and the secondary outcome, namely, the effect of tacrolimus in reducing the severity of MG, respectively. Results: After systematic retrieval, 13 researches with two randomized controlled trials (RCTs) and 11 prospective open-label single-arm clinical trials were included in the study. For the primary outcome of two RCTs, one RCT which was followed up for 1 year showed a positive effect and the other RCT which was associated with treatment duration of 28 weeks showed a negative result. For the secondary outcome, meta-analyses of other 11 trials showed a benefit effect, overall. For the quantitative MG (QMG) score, there were significant differences with high heterogeneity (SMD: 2.93; 95% CI: 1.14-4.73; I2 = 86%). In contrast, for MG activities of daily living (MGADL) score, it was reduced by tacrolimus with significant SMD and less heterogeneity (SMD: 0.59; 95% CI: 0.33-0.85; I2 = 7%). Adverse effects were mentioned as mild. Discussion: The opposite results of two RCTs showed that tacrolimus with enough treatment duration might have positive steroid-sparing effect. The most possible cause of heterogeneity in the outcome of QMG score between trials was the baseline severity of MG. Conclusion: The above finding suggests that there might be a potential beneficial role with no serious side effects of tacrolimus, and additional better RCTs including larger sample sizes and long-term study are needed to confirm or refute the results. PMID- 29184335 TI - Johann Bernhard Aloys von Gudden and the Mad King of Bavaria. AB - Bernhard von Gudden was a psychiatrist in Prussia and he was summoned in March 1886 to examine King Ludwig II for his apparently insane activities like, profligate spending and erratic behaviour. A team of four estimable psychiatrists pronounced that he was not capable ruling. Consequently, he was dethroned and kept in a castle under supervision of von Gudden. Gudden championed the idea of 'no restraint' and advocated free movement of insane persons and one evening in June, he accompanied the King during an evening stroll to a lake. A few hours later, the corpus of both of them were recovered under mysterious circumstances. Autopsy suggested that the King was drowned but no post-mortem examination was performed on von Gudden. There are plenty of controversies regarding their death like, murder, accidental death or even natural death from cardiac arrest following immersion in cold water, but no incontrovertible conclusion could be arrived at, even after scrupulous analysis by historians and even the diagnosis of insanity of the King has been doubted. Some even suggested that the opinion of psychiatrists were sought as a pretense in order to depose the King. PMID- 29184336 TI - Speech Signal Analysis and Pattern Recognition in Diagnosis of Dysarthria. AB - Background: Dysarthria refers to a group of disorders resulting from disturbances in muscular control over the speech mechanism due to damage of central or peripheral nervous system. There is wide subjective variability in assessment of dysarthria between different clinicians. In our study, we tried to identify a pattern among types of dysarthria by acoustic analysis and to prevent intersubject variability. Objectives: (1) Pattern recognition among types of dysarthria with software tool and to compare with normal subjects. (2) To assess the severity of dysarthria with software tool. Materials and Methods: Speech of seventy subjects were recorded, both normal subjects and the dysarthric patients who attended the outpatient department/admitted in AIMS. Speech waveforms were analyzed using Praat and MATHLAB toolkit. The pitch contour, formant variation, and speech duration of the extracted graphs were analyzed. Results: Study population included 25 normal subjects and 45 dysarthric patients. Dysarthric subjects included 24 patients with extrapyramidal dysarthria, 14 cases of spastic dysarthria, and 7 cases of ataxic dysarthria. Analysis of pitch of the study population showed a specific pattern in each type. F0 jitter was found in spastic dysarthria, pitch break with ataxic dysarthria, and pitch monotonicity with extrapyramidal dysarthria. By pattern recognition, we identified 19 cases in which one or more recognized patterns coexisted. There was a significant correlation between the severity of dysarthria and formant range. Conclusions: Specific patterns were identified for types of dysarthria so that this software tool will help clinicians to identify the types of dysarthria in a better way and could prevent intersubject variability. We also assessed the severity of dysarthria by formant range. Mixed dysarthria can be more common than clinically expected. PMID- 29184338 TI - Rapid Clinical Score for the Diagnosis of Tuberculous Meningitis: A Retrospective Cohort Study. AB - Objective: The aim of our study was to retrospectively validate a previously described rapid clinical score (RCS) in distinguishing tuberculous meningitis (TBM) from viral meningitis (VM) in people who are at increased risk of tuberculosis, as well as from cryptococcal meningitis (CM) in HIV-infected patients. Methods: We performed a retrospective study of patients admitted with a diagnosis of aseptic meningitis between January 2012 and December 2015, to a referral hospital for infectious diseases. The variables included in RCS were duration of symptoms before admission, neurological stage, cerebrospinal fluid (CSF) to blood glucose ratio, and CSF protein. We included in this retrospective study 31 patients with definite or probable TBM including 14 HIV-infected patients, 62 HIV-noninfected patients with VM, and 18 HIV-infected patients with CM. Results: The sensitivity of RCS to distinguish TBM from VM was 96.7%, with a specificity of 81.1% and the area under the receiver operating characteristic (ROC) curve was 0.949 (0.90-0.99). When all four criteria from the RCS were present, the specificity increased at 100%. In HIV-infected patients, the sensitivity and specificity of RCS in differentiating TBM from CM were 86.6% and 27.7%, respectively, and the area under the ROC curve was 0.669 (0.48-0.85). Conclusion: This easy-to-use RCS was found to be helpful in differentiating TBM from VM, with a better sensitivity than molecular amplification techniques and a relatively good specificity. However, the RCS was not useful to differentiate between TBM and CM in HIV-infected patients. PMID- 29184337 TI - Optical Coherence Tomography and Subclinical Optical Neuritis in Longitudinally Extensive Transverse Myelitis. AB - Objective: The aim is to compare the retinal nerve fiber layer (RNFL) thickness of longitudinally extensive transverse myelitis (LETM) eyes without previous optic neuritis with that of healthy control subjects. Methods: Over 20 LETM eyes and 20 normal control eyes were included in the study and subjected to optical coherence tomography to evaluate and compare the RNFL thickness. Result: Significant RNFL thinning was observed at 8 o'clock position in LETM eyes as compared to the control eyes (P = 0.038). No significant differences were seen in other RNFL measurements. Conclusion: Even in the absence of previous optic neuritis LETM can lead to subclinical axonal damage leading to focal RNFL thinning. PMID- 29184339 TI - Bone Health in Patients with Epilepsy: A Community-based Pilot Nested Case control Study. AB - Background: Antiepileptic drugs (AEDs) adversely affect bone health and there are reports describing association of alternations of bone and mineral metabolism in epileptic patients. Objectives: This study was undertaken to evaluate the bone profile (bone mineral parameters and bone mineral density [BMD]) of patients with epilepsy and compare them to their age-, gender-, and socioeconomic status matched healthy controls in a community. Materials and Methods: This was a nested case-control study conducted in fifty individuals, which included 25 cases (age above 18 years and on AEDs for at least 3 years) for which 25 controls were selected from the same community. Bone mineral parameters (serum calcium, proteins, phosphorous, alkaline phosphate, parathyroid hormone, and Vitamin D) and BMD were measured. Results: There was significant hypocalcemia (P = 0.003), hypoproteinemia (P = 0.014), hyperparathyroidism (P = 0.048), and increased levels of serum alkaline phosphatase (P = 0.019) in cases as compared to controls. The difference was insignificant in the serum levels of Vitamin D and phosphorous among both the groups. Vitamin D was significantly low in female patients as compared to males (P = 0.043). There was no significant difference in BMD at the lumbar spine and femur neck among both the groups. Mean duration of epilepsy was longest in patients with osteoporosis (23.6 years), and increasing duration of epilepsy was associated with reduction in age- and sex-corrected total BMD mean Z-score anteroposterior spine. There was negative correlation between cumulative drug load and T-score of patients with epilepsy. Conclusion: Patients on long-term AED treatment have altered bone profile as evident from biochemical parameters and reduced BMD. There is a need for more extensive research and that too on a larger sample size. PMID- 29184340 TI - Treatment-related Fluctuations in Guillain Barre Syndrome and the Conundrum of Additional Cycles of Plasmapheresis. AB - Introduction: In Guillain Barre syndrome (GBS), worsening of weakness or disability after initial period of recovery or stabilization is described as treatment-related fluctuations (TRF). Aim: This study aims to describe the clinical characteristics and outcome of six patients with GBS and TRF. Patients and Methods: Six patients with GBS fulfilling NINCDS criteria, evaluated at a tertiary care university hospital during 2008-2017, were diagnosed to have TRF. They form the basis of this report. Results: All patients were men and their mean age was 40 years. At presentation, mean duration of illness was 15 days; the illness had plateaued in three and progressive in other three patients. Two of the four patients had variant GBS. Initially, five patients were treated with large volume plasmapheresis (LVPP) and one patient with methyl prednisolone. At 17-28 days after disease onset, three patients developed new neurologic deficits (bilateral facial paresis in two; paralytic ileus in one). Other three patients with worsening of limb weakness (medical research council sum score of >5) and disability (Hughes disability grade by >=1) fulfilled Kleyweg's criteria for TRF. All the six patients were treated with the completion of five cycles or additional cycles of LVPP. Conclusion: Awareness about TRF is essential for correct diagnosis and management of patients with GBS. PMID- 29184341 TI - Atherosclerotic Carotid Plaques: Multimodality Imaging with Contrast-enhanced Ultrasound, Computed Tomography, and Magnetic Resonance Imaging. AB - Introduction: The imaging of carotid plaques has undergone a paradigm shift increasing importance being given to plaque characterization. Patients with "vulnerable" plaques are more prone to develop future neurovascular events. Purpose: The purpose of this study is to analyze the role of multimodality imaging techniques in the assessment of carotid atherosclerotic plaques. Materials and Methods: Twenty-six patients were prospectively enrolled in the study. Patients underwent multidetector computed tomography (CT) angiography, ultrasound, contrast-enhanced ultrasound, and high-resolution magnetic resonance imaging (MRI) of the carotid arteries with special emphasis on the carotid bifurcation. Results: The mean age of patients was 65.41 years. Twenty-one were males. Plaque neovascularization was seen in 10 of the 18 plaques studied (55.56%). Based on the predominant components of the plaque, plaques were characterized as lipid (3), lipid with recent hemorrhage (1), fibrous (7), fibrofatty (4), fibrofatty with some hemorrhagic components (3), and recent hemorrhage (2). Conclusions: Together, contrast-enhanced ultrasound, CT, and MRI provide complete information about the plaque characteristics. PMID- 29184342 TI - Risk Factors, Vascular Lesion Distribution, Outcome and Recurrence of Strokes Due to Intracranial Atherosclerosis: One Year Data from Hyderabad Stroke Registry. AB - Background: Intracranial atherosclerotic stenosis (ICAS) is a common cause of ischemic stroke in Asian countries and probably in India. Aim: The aim of this study was to describe the risk factors, distribution of vascular lesions, recurrence and outcome of stroke due to ICAS. Methodology: A total of 100 consecutive patients of ischemic stroke due to ICAS were enrolled prospectively from January 1, 2015, to December 31, 2015, and followed for 1 year for treatment compliance and recurrence. The details about demographics, risk factors, and vascular lesions were noted. Results: There were 68 males and 32 females. Hypertension (HTN), diabetes, alcohol, smoking, hyperlipidemia, and hyperhomocysteinemia was present in 82%, 52%, 34%, 33%, 28%, and 23%, respectively. The number of arteries involved were middle cerebral artery, 53 (37.3%); posterior cerebral artery, 24 (16.9%); internal cerebral artery, 21 (14.8%); vertebral artery, 18 (12.7%); basilar artery, 6 (4.2%); and anterior cerebral artery, 6 (4.2%). Seventeen (17%) patients had a recurrent stroke during 1 year follow-up. The presence of uncontrolled HTN and diabetes mellitus after discharge were significantly associated with stroke recurrence (P < 0.05). The use of dual antiplatelet agents and statins was found to have a significant effect in the prevention of recurrent stroke (P < 0.05). Severe stroke at presentation and presence of hemiparesis were the predictors for unfavorable outcome at 3 months (P < 0.05). Conclusion: Risk factors, distribution of vascular lesions and high recurrence of stroke due to ICAS in this study is similar to that reported from other Asian countries. Aggressive medical management and risk factor control remains the best strategy for preventing recurrence. PMID- 29184343 TI - Quality Indicators of Intravenous Thrombolysis from North India. AB - Background: Data on intravenous (IV) thrombolysis using tissue plasminogen activator (tPA) are limited from low- and middle-income countries. We aimed to assess the quality indicators of IV thrombolysis in our stroke unit. Methods: All stroke patients admitted in our hospital from October 2008 to April 2017 were included in this study. Data were collected prospectively by trained research staff in a detailed case record form. Outcome was assessed using modified Rankin Scale (mRS, 0-1 good outcome). Results: Of the total 4720 stroke patients seen, 944 (20%) came within window period (<4.5 h). Of these, 214 (4.5%) were eligible for thrombolysis and 170 (3.6%) were thrombolysed, relatives of 23 (23/214, 10.7%) patients denied consent, and 21 (9.8%) patients could not afford tPA. The mean age of thrombolysed patients was 58.4 (range 19-95) years. Median NIHSS at admission was 12 (interquartile range 2-24). Average onset-to-door (O-D) time was 76.8 (5-219) min, door-to-examination (D-E) time was 17.8 (5-105) min, door-to-CT (D-CT) time was 48 (1-205) min, and door-to-needle (D-N) time was 90 (20-285) min. At 6 months, 110 (64.7%) patients were contactable and 82 (74.5%) patients had good outcome (mRS 0-1). Conclusion: Thrombolysis rate has steadily increased at the center without undue adverse effects even in the elderly. D-E and D-CT times have reduced, but O-D and D-N times need further improvement. More patients could be thrombolysed if the cost of tPA is reduced and the consent process is waived. PMID- 29184344 TI - Nocardia Farcinica Brain Abscess in an Immunocompetent Old Patient: A Case Report and Review of Literature. AB - By definition, a brain abscess is an intraparenchymal collection of pus. Nocardia shows to have a special tropism for the neural tissue. Solitary abscess represents the most common manifestation in the central nervous system, accounting for 1%-2% of all cerebral abscesses. In this report, we present a case of primary multiple brain abscesses due to Nocardia farcinica in an immune competent patient. Early diagnosis and surgical intervention is significant for the patient. PMID- 29184345 TI - Vagus Nerve Stimulation Modulates Complexity of Heart Rate Variability Differently during Sleep and Wakefulness. AB - Progressive loss of heart rate variability (HRV) and complexity are associated with increased risk of mortality in patients with cardiovascular disease and are a candidate marker for patients at risk of sudden cardiac death. HRV is influenced by the cardiac autonomic nervous system (ANS), although it is unclear which arm of the ANS (sympathetic or parasympathetic) needs to be perturbed to increase the complexity of HRV. In this case-control study, we have analyzed the relation between modulation of vagus nerve stimulation (VNS) and changes in complexity of HRV as a function of states of vigilance. We hypothesize that VNS - being a preferential activator of the parasympathetic system - will decrease the heart rate (HR) and increase the complexity of HRV maximum during sleep. The electrocardiogram (EKG) obtained from a 37-year-old, right-handed male with known intractable partial epilepsy and left therapeutic VNS was analyzed during wakefulness and sleep with VNS ON and OFF states. Age-matched control EKG was obtained from five participants (three with intractable epilepsy and two without epilepsy) that had no VNS implant. The study demonstrated the following: (1) VNS increased the complexity of HRV during sleep and decreased it during wakefulness. (2) An increase in parasympathetic tone is associated with increased complexity of HRV even in the presence of decreased HR. These results need to be replicated in a larger cohort before developing patterned stimulation using VNS to stabilize cardiac dysautonomia and prevent fatal arrhythmias. PMID- 29184346 TI - Cutaneous Adverse Drug Reactions to Lamotrigine and Human Leukocyte Antigen Typing in North Indian Patients: A Case Series. AB - Cutaneous adverse drug reaction (cADR) has limited epidemiological data in India. The older antiepileptic drugs, i.e., carbamazepine, phenytoin, valproic acid, phenobarbitone, etc., induce severe cADRs that have a strong associated with human leukocyte antigen (HLA)-related genetic risk factors. There is also evidence of association of certain HLA alleles with lamotrigine (LTG)-induced cADRs, but this has not been reported in the Indian population. Here, we report case series of three patients with LTG-induced "Stevens-Johnson syndrome (SJS)." Their HLA-B typing was also performed which showed the presence of HLA-B*15:02 in one case with SJS. PMID- 29184347 TI - Anti Myelin Oligodendrocyte Glycoprotein associated Immunoglobulin G (AntiMOG IgG)-associated Neuromyelitis Optica Spectrum Disorder with Persistent Disease Activity and Residual Cognitive Impairment. AB - Antibodies targeting myelin oligodendrocyte glycoprotein (MOG) have been recently reported in association with idiopathic inflammatory central nervous system disorders. Initially believed to be a benign disorder, anti MOG-IgG was noted to cause steroid responsive recurrent optic neuritis and isolated longitudinally extensive myelitis. However, there is growing evidence that the disease may be predominantly relapsing, often producing severe visual loss and involving regions other than the spinal cord and optic nerve. We report an adolescent male with an aggressive disease course previously undescribed in anti MOG-IgG-associated disease that left him with residual cognitive dysfunction.

PMID- 29184350 TI - Female Caregivers and Stroke Severity Determines Caregiver Stress in Stroke Patients. AB - Background: Stroke is among the major causes of short- and long-term disability. This study aimed to understand the caregivers (CGs) stress in stroke survivors. Materials and Methods: A 22-item questionnaire was administered to 201 CGs of stroke survivors. The variables tested were physical and mental health, social support, financial, and personal problems. CGs were divided into Group A (Barthel index [BI] <75) and B (BI >75) according to patient's BI, according to gender (male and female CG) and relation; spouses (wife, husband), daughters, sons, daughter-in-law, grandchildren, and rest (father, mother, brother, sister, and in laws). Data were analyzed using SPSS software version-21. Data were analyzed to determine which variables of the patient effects the CG stress. Results: Majority of the CGs (74.62%) were females. 65% of CGs graded their burden as moderate to severe. 81% of CGs had left their work for caregiving. More than half of the CGs felt sleep disturbance and physical strain. Psychological instability and financial burdens were reported in 3/4th of CGs. Group A CGs faced more sleep, financial, health, and social life disturbance. Patient's bladder and bowel problems, shoulder pain, patients noncooperative attitude for medication administration, and physiotherapy were more upsetting for Group A CGs. Female CGs were subjected to more sleep disturbance, physical and psychological stress, faced more difficulty regarding the patient's bladder, bowel, personal hygiene needs, and physiotherapy. Female CGs felt less motivated in caregiving than male CGs. Wives and daughters-in-law experienced more burden. Time spent and burden perceived was more by female CGs (chi2 = 15.199, P = 0.002) than males (chi2 = 11.931, P = 0.018); wives and daughters than other relations (chi2 = 32.184, P = 0.000), (chi2 = 35.162, P = 0.019). Conclusion: Our study showed that caregiving burden was predominantly shouldered by females CGs. CGs faced physical, psychological, and socioeconomic burden. The burden was more evident in female CGs and in patients with severe stroke. PMID- 29184351 TI - Clinico-Electrophysiological and Genetic Overlaps and Magnetic Resonance Imaging Findings in Charcot-Marie- Tooth Disease: A Pilot Study from Western India. AB - Background: Charcot-Marie-Tooth (CMT) disease is clinically and genetically heterogeneous. There are no published series describing clinical, electrophysiological, and genetic information on CMT from the Indian subcontinent. Magnetic resonance imaging (MRI) neurography technique provides useful information about the plexus and roots and can be employed in patients with CMT. Settings and Design: A prospective, observational study carried out at a tertiary care hospital in Western India. Subjects and Methods: CMT patients fulfilling the UK Genetic Testing Network criteria were included. They underwent clinical, electrophysiological, radiological, and multigene panel testing. Results: Totally 22 patients (19 males, 3 females; 18 sporadic and 4 familial cases) were studied. Pes cavus (19), hammer toes (16), and scoliosis was seen in 1 patient. Electrophysiology revealed motor predominant neuropathy with 15 demyelinating (10 uniform and 5 multifocal) and 7 axonal patterns. Thickened lumbosacral plexuses on MRI neurography were evident in 6/10 studied patients, all 6 having demyelinating neuropathy. Genetic analysis identified PMP22, GJB1, SH3TC2, HSPB1, SPTLC2, MPZ, AARS, and NEFH gene mutations. Conclusions: This small series documents the pattern of CMT neuropathies as seen in Western India. Clinico-electrophysiological and genetic diagnosis showed general concordance some overlaps and reiterated advantages of gene panel testing in this heterogeneous group of neuropathies. MRI neurography was useful as an additional investigation to detect nerve enlargement in patients with demyelinating neuropathies.

AB - Aim: This study was performed to identify the non-cerebral Taenia multiceps cyst through molecular phylogeny of the 12S rRNA gene. Materials and Methods: Eight cyst samples were collected from 385 examined slaughtered goats during October 2015-September 2016 from three slaughterhouses in Chittagong City Corporation. Cysts were removed from the thigh muscle, and scolices were collected for light microscopic examination and molecular identification. The DNA was extracted and analyzed by polymerase chain reaction using 12S rRNA gene primers. Cyst samples were also preserved in 10% buffered formalin for histopathological study. Results: T. multiceps non-cerebral cyst is 2.1% prevalent in goat in this area. Under light microscopic examination, scolex was found with four suckers and a rostellum with the double crown of 32 hooks and hooklets. Molecularly, all the samples were amplified with 12S rRNA gene fragments yielded 270 base pair amplicon. Zenker's necrosis with focal to diffuse infiltration of lymphocytes and eosinophil was also found around the cyst wall in histopathological examination. Conclusion: Although the non-cerebral form of the cysts produced by T. multiceps is genetically identical with the cerebral cyst, previously published data indicated that cerebral T. multiceps cyst is predominant in other parts of the world as well as in Bangladesh. This study showed that non-cerebral cyst is also prevalent in this country which is very important for public health concern. This study depicts an idea of non-cerebral form of zoonotic T. multiceps cyst which will be helpful in taenia cyst control and prevention. PMID- 29184360 TI - Serological investigation of some important RNA viruses affecting sheep and goats in Giza and Beni-Suef governorates in Egypt. AB - Aim: The aim of this study was to investigate the seroprevalence of antibodies against foot and mouth disease (FMD), Peste des Petits ruminants (PPR), and bluetongue (BT) in sheep and goats within Giza and Beni-Suef governorates at the second half of 2016. Materials and Methods: A total of 300 animals (sheep and goats) randomly selected from small stocks with no history of previous vaccination against FMD virus (FMDV), PPR, or BT viruses (BTV) and examined with competitive enzyme-linked immunosorbent assay for detection of FMD-non-structural protein, PPR, and BT antibodies. Results: Seroprevalence analysis revealed that antibodies against FMDV were 40.8% and 37.1% at Giza governorate, while at Beni Suef governorate, the percent was 36.7% and 50% in sheep and goat, respectively. Antibodies against PPR were 63.8% in sheep and 45.7% in goats at Giza governorate, whereas the results for Beni-Suef governorate were 71.7% in sheep and 45% in goats. Antibodies against BT were 45% and 37% in sheep and goats, respectively, in Giza governorate, whereas the results for Beni-Suef governorate were 80% and 55% in sheep and goats, respectively. The average of BTV antibody prevalence was significantly higher in sheep (45% and 80%) than in goats (37% and 55%) in Giza and Beni-Suef, respectively. Statistical analysis for the three viruses showed the high relation between the two governorates in case of sheep (r=0.85) and in case of goats (r=0.87). In general, a strong positive correlation was observed between the governorates (r=0.93). Conclusion: Giza and Beni-Suef governorates are endemic with FMDV, PPR, and BTV. Regional plan for characterization and combating FMD, PPR, and BT is recommended to help in the achievement of the most suitable combination of the vaccine regimen. PMID- 29184361 TI - Phenotypic and genotypic characterization of antimicrobial susceptibility of avian pathogenic Escherichia coli isolated from broiler chickens. AB - Aim: Avian pathogenic Escherichia coli (APEC) is pathogenic strains of E. coli that are responsible for one of the most common bacterial diseases affecting poultry worldwide. This study was designed to determine the occurrence, antibiotic resistance profile, and antibiotic resistance genes of E. coli isolated from diseased and freshly dead broilers. Materials and Methods: In that context, a total of 200 broilers samples were examined by standard microbiological techniques for isolation of E. coli, and tested for their antimicrobial susceptibility against 15 antimicrobial agents using disc diffusion method. In addition, E. coli isolates were screened by multiplex polymerase chain reaction for detection of a number of resistance genes including aadA1 gene encodes streptomycin/neomycin, tetA encodes resistance to tetracycline, sul1 encodes sulfonamides, and beta-lactamase encoding genes (blaTEM and blaSHV). Results: A total of 73 (36.5%) isolates were biochemically identified as E. coli strains. O78, O2, and O1 are the most prevalent serotypes detected. E. coli displayed a high resistance against penicillin (100%), followed by cefepime (95.8%) and a low resistance to norfloxacin (36.9%), and chloramphenicol (30%). Depending on the results of PCR, sul1 gene was the most predominant antibiotic resistant gene (87%) followed by blaTEM (78%), tetA genes (60%), and aadA (54%). However, blaSHV had the lowest prevalence (23%). Conclusion: The obtained results demonstrated the importance of studies on APEC and antibiotic resistance genes in our region which associated with intensive poultry industry, aiming to acquire preventive measures to minimize losses due to APEC and associated multidrug resistance and resistance genes that of high significance to the rational use of antibiotics in clinical and public health. PMID- 29184362 TI - Analysis of spatial dynamic of epizootic process of bluetongue and its risk factors. AB - Aim: The study was undertaken to find out the spatial dynamic occurrence and patterns of the global spread of bluetongue (BT) disease for the period from 1996 to 2016, as well as the assessment of the risk of occurrence and its spread in 2017-2018. Materials and Methods: Outbreaks (serum samples were collected from clinically healthy as well as suspected animals in infected points) were confirmed and reported officially by veterinary departments which represent different geographical regions in the world to World Organization for Animal Health. These reports explained that ELISA and polymerase chain reaction were used to identify the BT disease, taking in the account number of infected, dead animals, and focus of BT infection in all susceptible animals from 1996 to 2016. Once conventional statistical population was defined (an observational study), we had classified data as well as possible to answer to our aim, using descriptive statistics methods, including the test of the relationship between different epizootiological indicators. Results: The spatial dynamic study of BT's occurrence and its spread in the world over the two past decades was presented by different epizootic indicators. The given analysis includes assessment and measurement of risk factors. It was built too, regression models, and allowed to put different forecasts on the different epizootic indicators in the years 2017 2018 by the extrapolation method. We had also determined that, in 2017, BT continues to spread with the total expectancy of 3.4 focus of infection (number of diseased animals in a single unfavorable point) and mortality of about 26 %; these rates tend to decrease in 2018. At abused points by BT, up to 78.4% of animals are mixed (more than one type) and in 21.6% - uniform. By this way, the relative risk of the incidence of appearance-abused points in mixed households has 3.64, which might be considered higher for the BT dissemination. Moreover, between the enzootic index and other epizootiological indicators had revealed an inverse correlation, i.e., to an increase in the level of enzootic index among the cattle population would be formed population less sensitive to BT. Cluster analysis was done, which had demonstrated the zoning of risk levels in the world and the occurrence of the disease intensity in the period 1996-2016 years. Then, assess connection degree of the dynamic of BT tension with geographical and socioeconomic conditions background 0.66 and 0.68, respectively. Conclusion: It is important to define a variety of BT risk factors and assess their influence on BT occurrence. However, the most important is to define the overlapping coinfluence between them that cause serious losses. To have an out of BT territory needs to make an emphasis of co-influence of risk factors on this zone. Was predicted a continue hits of disease in the next year with weight moderation through one year. Far from statists, to assess the given forecast may have a serious variety, taken in account problems of actual climate change in the world. PMID- 29184363 TI - Effect of antioxidants supplementation on the quality of Beetal buck semen stored at 4 degrees C. AB - Aim: An experiment was designed to evaluate the role of Vitamin E and glutathione in improving the seminal parameters during hypothermic storage of liquid semen at 4 degrees C for 72 h. Materials and Methods: Thirty-six semen ejaculates were collected by artificial vagina from 6 bucks (Beetal) during the normal reproduction season (September to November) at weekly interval. The samples were centrifuged, and the seminal plasma was removed. The sperm pellet was diluted with Tris-based extender and divided into three groups. Group T1: Control samples without antioxidants, Group T2: Samples supplemented with tocopherol at 3 mM, and Group T3: Samples supplemented with glutathione at 1 mM. The samples were evaluated for progressive motility, percent liveability, percent abnormal spermatozoa, and acrosome integrity after liquid preservation for 0, 24, 48, and 72 h. The level of lipid peroxidation and antioxidant enzymes, namely, glutathione peroxidase (GPx) and superoxide dismutase (SOD) were estimated after liquid preservation for 0 and 72 h. Results: It was observed that, after storage of semen at 4 degrees C up to 72 h, the progressive sperm motility, percent liveability, percent abnormal spermatozoa, and percent intact acrosomes were significantly (p<0.05) higher in group T2 and T3 samples as compared to control. However, the level of lipid peroxidation in T2 and T3 groups was significantly (p<0.05) lower after 72 h of incubation at 4 degrees C. Similarly, GPx and SOD values were significantly (p<0.05) increased in T2 and T3 groups after 72 h of storage at 4 degrees C. Conclusion: Thus, it can be concluded that Vitamin E and glutathione supplementation at 3 mM and 1 mM, respectively, while preserving the semen samples at 4 degrees C helped in maintaining the seminal parameters up to 72 h and protected the spermatozoa from oxidative damage. PMID- 29184364 TI - Seroprevalence of Fasciolagigantica infection in bovines using cysteine proteinase dot enzyme-linked immunosorbent assay. AB - Aim: The objective of the present study was to know the seroprevalence status of Fasciola gigantica infection in cattle and buffaloes using cysteine proteinase (CP) antigen in dot enzyme-linked immunosorbent assay (ELISA) format under field conditions. Materials and Methods: As per the standard protocol, the sera were collected from the blood of 112 cattle and 38 buffaloes of coastal areas of Navsari district, South Gujarat, India. The indirect ELISA was performed on the strip of nitrocellulose paper blotted with 1 ul of CP antigen, to detect F. gigantica seropositive animals. Results: The native CP of F. gigantica revealed a single visible band on 10% sodium dodecyl sulfate-polyacrylamide gel electrophoresis. There was no any noted cross-reaction between the selected antigen and sera of Gastrothylax crumenifer-infected animals in ELISA. Out of 150 screened bovines, the sera of 47 (31.33%) were found to be reactive in dot-ELISA, with a prevalence rate of 31.25% and 31.58% in cattle and buffaloes, respectively. The seropositive bovines with heavy, moderate, and light level of infection were 44.68%, 34.04%, and 21.28%, respectively (p<0.05 between heavy and light; p>0.05 between moderate and heavy or light). The share of F. gigantica seropositive and negative animals was 31% and 69%, respectively. The optical density at 450 nm of pooled sera of seropositive bovines with heavy, moderate, and light reactivity in plate-ELISA was significantly higher with field or reference -negative sera. Conclusion: The CP-based dot-ELISA can be useful for field veterinarians for quick and timely isolation of the animals requiring urgent flukicide therapy. PMID- 29184365 TI - Public health concerns of highly pathogenic avian influenza H5N1 endemicity in Africa. AB - Highly pathogenic avian influenza virus (HPAIV) H5N1 was first officially reported in Africa in 2006; thereafter this virus has spread rapidly from Nigeria to 11 other African countries. This study was aimed at utilizing data from confirmed laboratory reports to carry out a qualitative evaluation of the factors responsible for HPAI H5N1 persistence in Africa and the public health implications; and to suggest appropriate control measures. Relevant publications were sought from data banks and repositories of FAO, OIE, WHO, and Google scholars. Substantiated data on HPAI H5N1 outbreaks in poultry in Africa and in humans across the world were mined. HPAI H5N1 affects poultry and human populations, with Egypt having highest human cases (346) globally. Nigeria had a reinfection from 2014 to 2015, with outbreaks in Cote d'Ivoire, Ghana, Niger, Nigeria, and Burkina Faso throughout 2016 unabated. The persistence of this virus in Africa is attributed to the survivability of HPAIV, ability to evolve other subtypes through genetic reassortment, poor biosecurity compliance at the live bird markets and poultry farms, husbandry methods and multispecies livestock farming, poultry vaccinations, and continuous shedding of HPAIV, transboundary transmission of HPAIV through poultry trades; and transcontinental migratory birds. There is, therefore, the need for African nations to realistically reassess their status, through regular surveillance and be transparent with HPAI H5N1 outbreak data. Also, it is important to have an understanding of HPAIV migration dynamics which will be helpful in epidemiological modeling, disease prevention, control and eradication measures. PMID- 29184366 TI - Polymerase chain reaction detection of genes responsible for multiple antibiotic resistance Staphylococcus aureus isolated from food of animal origin in Egypt. AB - Aim: The aim of our study was polymerase chain reaction (PCR) detection of the genes responsible for the multiple antibiotic resistance S. aureus isolated from food of animal origin in Egypt. Materials and Methods: A total of 125 samples were randomly collected from milk, meat, and their products from Giza and Beni Suef Governorates markets. The S. aureus isolates were subjected to antimicrobial sensitivity tests using four antibacterial disks (Oxoid), and then the polymerase chain reaction (PCR) was performed for detection of antibiotic resistance genes. Results: Out of 125 samples, 19 S. aureus isolates were detected. All detected isolates were multiple drug resistance (MDR). The penicillin-, erythromycin-, kanamycin-, and tetracycline-resistant isolates were examined by PCR for resistance genes blaZ, (msrA, ermB, and ermC), aac(6')aph (2"), and tetK. The isolates harbored these resistance genes with percentage of 100% (100%, 0%, and 100%), 62.5%, and 100%, respectively. Conclusion: Contaminated foods of animal origin may represent a source of MDR S. aureus that can be a major threat to public health. PMID- 29184367 TI - Protective efficacy of combined trivalent inactivated ISA 71 oil adjuvant vaccine against avian influenza virus subtypes (H9N2 and H5N1) and Newcastle disease virus. AB - Aim: The objective of the present study was to prepare a trivalent inactivated vaccine of Newcastle disease virus (NDV), H5N1, and H9N2 viruses. Materials and Methods: Three monovalent and a trivalent vaccines were prepared by emulsifying inactivated NDV (LaSota strain), reassortant H5N1, and H9N2 viruses with Montanide ISA 71 oil adjuvant. Parameters used for evaluation of the efficacy of the prepared vaccines in specific pathogen-free chickens were cellular immunity assays (blastogenesis, interferon gamma, interleukin 1 [IL1], and IL6), humoral immunity by hemagglutination inhibition, protection percentage, and shedding. Results: A single immunization with trivalent vaccine-enhanced cell-mediated immunity as well as humoral immune response with 90% protection against challenges with highly pathogenic avian influenza (HPAI) H5N1 and low pathogenic (LP) avian influenza H9N2 viruses with 100% protection after challenge with NDV. Conclusion: Development and evaluation of the trivalent vaccine in the study reported the success in preparation of a potent and efficacious trivalent vaccine which is a promising approach for controlling HPAI H5N1, LP H9N2, and ND viral infections. PMID- 29184368 TI - West African donkey's liveweight estimation using body measurements. AB - Aim: The objective of this study was to determine a formula for estimating the liveweight in West African donkeys. Materials and Methods: Liveweight and a total of 6 body measurements were carried out on 1352 donkeys from Burkina Faso, Mali, Niger, and Senegal. The correlations between liveweight and body measurements were determined, and the most correlated body measurements with liveweight were used to establish regression lines. Results: The average weight of a West African donkey was 126.0+/-17.1 kg, with an average height at the withers of 99.5+/-3.67 cm; its body length was 104.4+/-6.53 cm, and a heart girth (HG) of 104.4+/-6.53 cm. After analyzing the various regression lines and correlations, it was found that the HG could better estimate the liveweight of West African donkeys by simple linear regression method. Indeed, the liveweight (LW) showed a better correlation with the HG (R2=0.81). The following formulas (Equations 1 and 2) could be used to estimate the LW of West Africa donkeys.Equation 1: Estimated LW (kg) = 2.55 * HG (cm) - 153.49. Conclusion: The above formulas could be used to manufacture weighing tape to be utilized by veterinary clinicians and farmers to estimate donkey's weight in the view of medication and adjustment of load. PMID- 29184369 TI - Clinicopathological alterations in naturally occurring Babesia gibsoni infection in dogs of Middle-South Gujarat, India. AB - Aim: The present research work was undertaken to describe various clinical signs and hematobiochemical alterations in dogs affected with Babesia gibsoni. Materials and Methods: Blood smears from a total of 79 suspected dogs of Anand region as well as Surat region of Gujarat state (India) were screened for detection of intraerythrocytic piroplasm of small form of Babesia. Diagnosis was made on the basis of clinical signs and demonstration of B. gibsoni organism in Giemsa-stained thin blood smears. The clinical signs were recorded at the time of presentation, and blood samples were subjected to estimation of hematobiochemical parameters by auto hematology analyzers at College of Veterinary Science and Animal Husbandry, Anand. Statistical analysis, interpretation, and comparison of hematobiochemical changes with scientific literature were carried out to understand the pathophysiology of the disease. Results: Out of 79 dogs, 16 were positive for naturally occurring babesiosis based on the presence of intraerythrocytic piroplasm of small form of Babesia in blood smears. The clinical cases were manifested by wide variety of non-specific clinical signs. The hematological evaluation revealed that the mean values of hemoglobin and total erythrocyte counts in dogs with babesiosis decreased significantly (p<0.01) in comparison to healthy dogs. Among differential leukocyte count, mean values of neutrophils and eosinophils increased while lymphocytes decreased (p<0.01) in dogs with babesiosis in comparison to healthy dogs. Serum biochemistry revealed increase (p<0.01) value of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, and globulin as well as decrease in albumin levels (p<0.05) in dogs with babesiosis as compared to healthy dogs. Conclusion: B. gibsoni is having multisystemic effects with atypical hematobiochemical changes in dog are discussed here, which would aid new insights in diagnosis of disease. PMID- 29184371 TI - Epidemiology of bovine fascioliasis in the Nile Delta region of Egypt: Its prevalence, evaluation of risk factors, and its economic significance. AB - Aim: This study focuses on the risk factors associated with the prevalence of Fasciola affecting cattle population in three provinces belonging to the Nile Delta of Egypt and to estimate the economic losses as a result of fascioliasis. Materials and Methods: From January 2015 to end of December 2015, records of 21 farms (4976 cattle) were analyzed to screen the prevalence of fascioliasis among cattle farms, to identify its associated risk factors and its economic impacts on Nile Delta region of Egypt. Results: The overall prevalence of fascioliasis in the Nile Delta region of Egypt was 9.77%. The prevalence of fascioliasis was found to be statistically significantly associated with age, sex, breed, and type of farms. The highest prevalence was observed in <2 age group (10.91%), and the lowest was >3 age groups (8.35%). In terms of body condition scores, cattle with medium and poor conditions were associated with fascioliasis more than those with good body condition. Besides, cattle raised in organic farms were associated with lower risk of fascioliasis than those in conventional farms. The prevalence of fascioliasis was noted more prominent in districts with moderate temperatures and with relative humidity (>60%). The annual overall costs for fascioliasis were estimated to be 221.2 USD/cow due to the significant reduction in body weight, reduction in milk production, and the treatment costs for fascioliasis. Conclusion: The results provided could be helpful for improving the control and preventive strategies. PMID- 29184370 TI - Occurrence of virulent and antibiotic-resistant Shiga toxin-producing Escherichia coli in some food products and human stool in Egypt. AB - Aim: Shiga toxin-producing Escherichia coli (STEC) represent a severe public health issue worldwide, causing life-threatening diseases in the human gastrointestinal tract. This study aimed to determine the occurrence of virulent and antibiotic-resistant STEC in retail meat and milk products and human stool samples and to characterize the genes encoding for virulence and antibiotic resistance among the identified STEC isolates. Materials and Methods: A total of 260 food samples were randomly collected from retail markets in different localities of El Giza Governorate, Egypt. 50 stool specimens were obtained from children that had diarrhea at Embaba Fever Hospital. All collected samples were initially subjected to bacteriological examination and serotyping, and then subsequently, the isolates were exposed to polymerase chain reaction application and sequencing for the identification of the virulence-related genes. Finally, the virulent STEC isolates were tested for antibiotic susceptibility. Results: Serotyping of the 76 biochemically identified isolates showed that 18 were STEC with a predominance of non-O157 (16) while 2 O157:K-serotype was detected only in one food and one human isolate. Molecular identification of the virulence genes illustrated that the minced meat showed the highest prevalence of STEC (8%) as compared to the other food products. In the humans, the O157 was the only serotype that expresses the Shiga toxin-associated gene (eaeA). Antibiotic susceptibility test displayed that 13 of the 17 food and human isolates (76.47%) were resistant to cephalothin (KF30). 9 of the 13 cephalothin-resistant isolates harbor the beta lactamase (blaTEM )-resistant gene. All isolates were sensitive to chloramphenicol, ciprofloxacin, amikacin, and gentamicin. DNA sequencing and phylogenetic analysis of the stx2-positive minced meat isolate revealed a high genetic relatedness with beef minced meat from the USA and Australia. Conclusion: This study showed the predominance of non-O157 among the identified isolates. Minced meat showed the highest prevalence of STEC as compared to the other food products, and this work illustrates the necessity to consider the food products as a potential source of the non-O157 STEC serotypes. DNA sequencing and phylogenetic analysis revealed a high genetic relatedness with beef minced meat from the USA and Australia. This highlights the high probability of worldwide spread of such serotypes, signifying the importance of the one world concept. PMID- 29184372 TI - Factors influencing growth hormone levels of Bali cattle in Bali, Nusa Penida, and Sumbawa Islands, Indonesia. AB - Aim: Bali cattle (Bos javanicus) are an Indonesian's native cattle breed that distributed in Asia to Australia. The scientific literature on these cattle is scarce. The growth hormone (GH) of Bali cattle is investigated from three separated islands, namely, Bali, Nusa Penida, and Sumbawa. Materials and Methods: Forty plasma samples were collected from each island, and the GH was measured using a commercial enzyme-linked immunosorbent assay kit. The data were analyzed based on the origin, sex, and cattle raising practices. Results: We found that the GH level (bovine GH [BGH]) of animal kept in stall 1.72+/-0.70 ug/ml was higher than free-grazing animal 1.27+/-0.81 ug/ml. The GH level was lower in female (1.22+/-0.62 ug/ml) compared to male animals (1.77+/-0.83 ug/ml). Conclusion: We conclude that the level of BGH in Bali cattle was low and statistically equal from all origins. The different level was related to sex and management practices. Further validation is needed through observing the growth rate following BGH administration and discovering the inbreeding coefficient of the animal in Indonesia. PMID- 29184373 TI - Occurrence, treatment protocols, and outcomes of colic in horses within Nairobi County, Kenya. AB - Aim: The aim of this study was to determine the treatments and their outcomes in horses with colic in Nairobi County, Kenya. Materials and Methods: This is a retrospective study to determine the occurrence, treatments, pain management, and outcomes of colic in horses in Nairobi County. Association between pain management protocols and the outcomes of colic with regard to recovery or death was also determined. Data collected from four equine practitioners were organized manually and given numerical codes as appropriate to facilitate entry into the computer. The coded data were entered into Microsoft Excel 2010 and exported to StatPlus pro 5.9.8 statistical package for analysis. Simple association tests were done between various factors and occurrence of colic. Results: The incidence of colic for the 11 years was 3.1%, which constituted 68.0% spasmodic colic, 27.8% impaction colic, and 4.2% displacement colic. Flunixin meglumine as a nonsteroidal anti-inflammatory drug (NSAID) was used as the only pain management treatment in 85.3% of the cases, flunixin meglumine and butorphanol as NSAID OPIOD combination in 6.4% of the cases, while buscopan as an antispasmodic was recorded in 5.9% of the cases mainly in spasmodic colic. Univariate analysis revealed simple association between various factors and the type of colic a horse was having. There was an association between the type of colic and the decision making on the pain management protocol to use, whether single analgesic protocol (chi2=22.5, p<0.001) or use of analgesic combinations (chi2=18.3, p<0.001). The type of colic strongly influenced the decision for performing nasogastric intubation (chi2=265, p<0.001), but performing nasogastric intubation was weakly (chi2=4.9, p=0.03) associated with horse recovery from colic. Type of colic also strongly influenced the need for the use of metabolic stimulants, particularly vitamin B-complex (chi2=99.3, p<0.001). Recovery or death of the horse from colic was strongly associated with the type of colic (chi2=250, p<0.001). The possibility of recurrence of colic was weakly (chi2=4.6, p=0.04) determined by the type of colic, a horse had. Multivariate logistic regression revealed that the main cause of death was intestinal displacement and the majority of the horses with intestinal displacement died (beta-estimate 2.7, odds ratio=0.07, p=0.007) compared to horses that had impaction colic. Conclusion: The incidence of colic is 3.1%, and the most common type of colic is spasmodic followed by impaction. The most common pain management protocol for colic is NSAIDs, mainly flunixin meglumine, followed by flunixin-butorphanol combination. Surgery for horses with colic in Nairobi County is not commonly done due to impeding poor prognoses. The horse owners tend to prefer euthanasia for such cases. PMID- 29184374 TI - Molecular characterization of Escherichia coli recovered from traditional milk products in Kashan, Iran. AB - Aim: Shiga toxigenic Escherichia coli (STEC) strains as emerging groups of foodborne pathogens are responsible for most foodborne illnesses. The aim of this study was to determine the antibiotic resistance pattern in STEC isolated from traditional milk products and their molecular characterization. Materials and Methods: A total of 116 samples were randomly purchased from local markets in Kashan, Iran, and evaluated for the occurrence of STEC by culturing and molecular methods. The antibiotic resistance of obtained isolates was determined by Kirby Bauer method. Furthermore, isolates were assayed for the presence of Shiga toxins (stx1 and stx2) and intimin gene (eae). Results: The incidence of E. coli in 60 ice cream, 30 yoghurt, and 26 cheese samples was 8.33%, 10%, and 11.54%, respectively. The findings showed that 11 out of 11 (100%) E. coli had both stx1 and stx2 while eae gene was not found in E. coli isolated of traditional milk products. For E. coli strains carrying stx1 and stx2, highest antibiotic sensitive levels were related to trimethoprim/sulfamethoxazole, norfloxacin, chloramphenicol, and ciprofloxacin, respectively. Conclusion: The results showed relationship between the presence of virulence factors and antimicrobial resistance. These results can be used for further studies on STEC as an emerging foodborne pathogen. PMID- 29184375 TI - Biochemical analysis of some serum trace elements in donkeys and horses in Eastern region of Kingdom of Saudi Arabia. AB - Aim: Little is known about the serum levels of trace elements in donkeys and horses in Saudi Arabia. This study aimed to investigate the levels of some trace elements in these two species in the eastern region of Saudi Arabia and to compare the obtained results with the reference values. Materials and Methods: Seventeen Arabian horses and twenty eight Hassawi donkeys were randomly selected for this study. All of the studied healthy animals were kept under a uniform feeding protocol without any minerals supplementations. Atomic absorption spectrometer is used to estimate the serum concentrations of selenium (Se), manganese (Mn), chromium (Cr), copper (Cu), iron (Fe), and zinc (Zn) in the analyzed samples. Results: Significant differences between horses and donkeys were observed in three of the studied elements (Se, Mn, and Cr). Statistically significant differences were found in serum Se and Cr between male and female horses. The male donkey showed higher Mn, Cu, and Zn levels than female animals. Conclusion: The obtained results of trace element levels in serum of Hassawi donkeys and Arabian horses in Saudi Arabia are considered as the first values to be published for these breeds. When compared to other animals, the measured amounts of Se, Mn, Cr, Cu, Fe, and Zn in the serum of horses and donkey are often differed, possibly because of the varying living or feeding conditions. Moreover, there were some differences in some of the trace elements concentrations related to animal's gender and species (horses and donkeys), which will be considered in the interpretation of the laboratory data. PMID- 29184376 TI - Bovine origin Staphylococcus aureus: A new zoonotic agent? AB - Aim: The study aimed to assess the nature of animal origin Staphylococcus aureus strains. The study has zoonotic importance and aimed to compare virulence between two different hosts, i.e., bovine and ovine origin. Materials and Methods: Conventional polymerase chain reaction-based methods used for the characterization of S. aureus strains and chick embryo model employed for the assessment of virulence capacity of strains. All statistical tests carried on R program, version 3.0.4. Results: After initial screening and molecular characterization of the prevalence of S. aureus found to be 42.62% in bovine origin samples and 28.35% among ovine origin samples. Meanwhile, the methicillin resistant S. aureus prevalence is found to be meager in both the hosts. Among the samples, only 6.8% isolates tested positive for methicillin resistance. The biofilm formation quantified and the variation compared among the host. A Welch two-sample t-test found to be statistically significant, t=2.3179, df=28.103, and p=0.02795. Chicken embryo model found effective to test the pathogenicity of the strains. Conclusion: The study helped to conclude healthy bovines can act as S. aureus reservoirs. Bovine origin S. aureus strains are more virulent than ovine origin strains. Bovine origin strains have high probability to become zoonotic pathogen. Further, gene knock out studies may be conducted to conclude zoonocity of the bovine origin strains. PMID- 29184377 TI - Virulence and extended-spectrum beta-lactamase encoding genes in Escherichia coli recovered from chicken meat intended for hospitalized human consumption. AB - Aim: This study describes the prevalence of Escherichia coli in frozen chicken meat intended for human consumption with emphasis on their virulence determinants through detection of the virulence genes and recognition of the extended-spectrum beta-lactamase (ESBL) encoding genes (blaOXA and blaTEM genes). Materials and Methods: A total of 120 frozen chicken meat samples were investigated for isolation of E. coli. All isolates were subjected to biochemical and serological tests. Eight serotypes isolated from samples were analyzed for the presence of various virulence genes (stx1, stx2, and eae A genes) using multiplex polymerase chain reaction (PCR) technique. Moreover, the strains were evaluated for the ESBL encoding genes (blaTEM and blaOXA). Results: Overall, 11.66% (14/120) chicken meat samples carried E. coli according to cultural and biochemical properties. The most predominant serotypes were O78 and O128: H2 (21.5%, each), followed by O121: H7 and O44: H18. Molecular method detected that 2 strains (25%) harbored stx1, 3 strains (37.5%) stx2, and 3 strains (37.5%) both stx1 and stx2, while 1 (12.5%) strain carried eae A gene. Particularly, only O26 serotype had all tested virulence genes (stx1, stx2, and eae A). The results revealed that all examined 8 serotypes were Shiga toxin-producing E. coli (STEC). The ESBL encoding genes (blaTEM and blaOXA) of STEC were detected in 4 (50%) isolates by multiplex PCR. The overall incidence of blaTEM and blaOXA genes was 3 (37.5%) and 2 (25%) isolates. Conclusion: The present study indicates the prevalence of virulent and ESBL-producing E. coli in frozen chicken meat intended for hospitalized human consumption due to poor hygienic measures and irregular use of antibiotics. Therefore, the basic instructions regarding good hygienic measures should be adapted to limit public health hazard. PMID- 29184378 TI - Survivin expression in canine spontaneous cutaneous and subcutaneous tumors and its prognostic importance. AB - Aim: The present study was carried out to know the expression level of survivin, an inhibitor of apoptosis protein with an objective to determine its prognostic importance in cutaneous and subcutaneous tissue tumors of dogs. Materials and Methods: Forty cases of canine cutaneous and subcutaneous tissue tumors on histopathological examination revealed various round cell, epithelial, and mesenchymal cell tumors. Survivin gene expression was detected in all tumors tested by TaqMan real-time polymerase chain reaction assay by comparative cycle threshold method. Results: The mean survivin gene expression value of benign tumors was 0.94+/-0.63 folds and that of malignant tumors was 18.87+/-5.30 folds. Postsurgical follow up of 30 malignant tumor cases revealed death in 8, recurrence in 7, and neoplastic free alive status in 15 dogs with mean survivin fold difference values of 48.49+/-12.39, 14.63+/-6.37, and 5.034+/-2.27, respectively. The mean survivin gene expression value was significantly higher in malignant (30 cases, 18.87+/-5.30) compared to benign tumors (10 cases, 0.94+/ 0.63), and it varied between various postsurgical follow-up groups (p<0.05). Survival analysis, using survivin gene expression median cutoff value of 3.74 in 30 malignant tumors, was performed to predict probable survival period in malignant cutaneous and subcutaneous tumors of dogs. Conclusions: Results of the present study indicated that the expression of survivin in canine cutaneous and subcutaneous tumors has prognostic value, and survivin expression greater than median cutoff value of 3.74 has a poor prognosis.

AB - The Argentinean Flag Sign is a complication that occurs during capsulorhexis construction, in which the capsulorhexis extends to the periphery due to lens intumescence. Phaco capsulotomy is a technique in which the phacoemulsification tip is used to simultaneously create the initial tear in the anterior capsule and remove a portion of the intumescent lens, thereby debulking and relieving pressure from the lens and capsule, and preventing the Argentinean Flag Sign. A detailed description of the phaco capsulotomy technique is provided, including applications and potential complications. PMID- 29184383 TI - Prevalence and factors associated with childhood visual impairment in Ethiopia. AB - Background: Visual impairment is a significant loss of vision. It has an impact on the prosperity of different countries. It has been difficult to plan preventive measures against visual impairment due to the scarcity of data about the extent of the problem. Objectives: The study was aimed at assessing the prevalence and identifying factors associated with visual impairment among school age children in Ethiopia. Materials and methods: A cross-sectional study design was used in four randomly selected schools found in Addis Ababa from May 15 to June 14, 2016. A total of 804 school-age students were selected using the simple random sampling method. Bivariable logistic regression and multivariable logistic regression were conducted. A p-value <0.05 was taken as a significant association. Results: A total of 718 students participated in the study, obtaining a response rate of 89.3%. In all, 7.24% of school-age children were visually impaired, of whom 3.9% had low vision and 3.34% had severe visual impairment. Factors associated with visual impairment were being female (adjusted odds ratio [AOR], 2.28; 95% confidence interval [CI], 1.06-3.50), being in the age group of 10-13 years (AOR, 2.94; 95% CI, 1.36-6.22), being in the age group of 14-18 years (AOR, 4.06; 95% CI, 2.17-11.95), being a private school student (AOR, 2.61; 95% CI, 1.81-4.41), watching television for 2-4 hours/day (AOR, 3.56; 95% CI, 1.37-7.34), watching television at <1 m (AOR, 7.65; 95% CI, 2.59-34.61), watching television at 1-2 m (AOR, 6.89; 95% CI, 1.74-25.27), mobile exposure for 2-4 hours/day (AOR, 2.61; 95% CI, 1.35-4.58), mobile exposure for >4 hours/day (AOR, 3.05; 95% CI, 1.41-9.18), medical visit while experiencing symptoms (AOR, 11.32; 95% CI, 1.80-82.25) and no medical visit experience (AOR, 3.84; 95% CI, 0.46-31.76). Conclusion: The majority of the visually impaired school-age children had low vision. Sex, age, school type, television exposure duration, the distance of television exposure, mobile exposure and medical visit were factors associated with visual impairment. Increasing community awareness about early detection of visual impairment and providing affordable eye health service may decrease the prevalence of visual impairment. PMID- 29184384 TI - Treatment of refractory uveitic macular edema: results of a first and second implant of long-acting intravitreal dexamethasone. AB - Purpose: The purpose of this study was to report the functional and anatomical outcomes of a prospective study resulting from repeated dexamethasone intravitreal implants in patients with uveitic refractory macular edema. Methods: Twelve eyes of 9 patients with intermediate and posterior noninfectious inflammatory uveitis complicated with refractory macular edema were regularly reviewed after a dexamethasone intravitreal implant. Patients were examined at baseline, 30, 90, 135, and 180 days with best-corrected visual acuity (BCVA), complete slit-lamp examination, intraocular pressure (IOP), optical coherence tomography, and fluorescein angiography. After 6 months of follow-up, eyes were reassessed to receive a second implant. Results: BCVA significantly improved when comparing the baseline values after the first and second implant (16.2 and 25.8 letters, respectively, 9.6 letters improvements, p<0.05). BCVA was better after the second implant compared to the first one throughout the follow-up, but without statistical significance. Mean central macular thickness (CMT) was 446.3+/-129.9 MUm at baseline and was significantly reduced until day 135 (p<0.05). CMT reductions after the second injection showed a similar pattern, though differences were not statistically significant. Cataract progression was observed in 4 of 8 phakic eyes (50%) after the first implant, and in 2 of 3 phakic eyes following the second implant, with 1 eye requiring cataract surgery. One eye developed an IOP >30 mmHg 30 days after the second implant, treated topically. Conclusion: Repeated dexamethasone intravitreal implants in uveitic patients with refractory macular edema can be used effectively in a clinical setting with an acceptable safety profile. PMID- 29184385 TI - Aflibercept treatment for neovascular AMD beyond the first year: consensus recommendations by a UK expert roundtable panel, 2017 update. AB - National recommendations on continued administration of aflibercept solution for injection after the first year of treatment for neovascular age-related macular degeneration (nAMD) have been developed by an expert panel of UK retina specialists, based on clinician experience and treatment outcomes seen in year 2. The 2017 update reiterates that the treatment goal is to maintain or improve the macular structural and functional gains achieved in year 1 while attempting to reduce or minimize the treatment burden, recognizing the need for ongoing treatment. At the end of year 1 (ie, the decision visit at month 11), two treatment options should be considered: do not extend the treatment interval and maintain fixed 8-weekly dosing, or extend the treatment interval using a treat and-extend regimen up to a maximum 12 weeks. Criteria for considering not extending the treatment interval are persistent macular fluid with stable vision, recurrent fluid, decrease in vision in the presence of fluid, macular hemorrhage, new choroidal neovascularization or any other sign(s) of exudative disease activity considered vision threatening in the opinion of the treating clinician. Treatment extension is recommended for eyes with a dry macula (ie, without macular fluid) and stable vision. Under both options, the treatment interval may be shortened if visual and/or anatomic outcomes deteriorate. Monitoring without treatment may be considered for eyes with a fluid-free macula for a minimum duration of 48 weeks. A patient completing one full year of monitoring without requiring injections may be considered for discharge from clinic. The treatment algorithm incorporates return to fixed 8-weekly dosing for disease reactivation during treatment extension and reinstatement of treatment for disease recurrence following discontinuation or discharge. For bilateral nAMD, either the eye requiring the more intensive treatment or the eye with the better vision, guided by local clinical practice, should determine the retreatment schedule overall. PMID- 29184386 TI - Novel grid combined with peripheral distortion correction for ultra-widefield image grading of age-related macular degeneration. AB - Purpose: Eyes with age-related macular degeneration (AMD) often harbor pathological changes in the retinal periphery and perimacular region. These extramacular changes have not been well classified, but may be phenotypically and functionally relevant. The purpose of this study was to demonstrate a novel grid to systematically study peripheral retinal abnormalities in AMD using geometric distortion-corrected ultra-widefield (UWF) imaging. Methods: This is a cross sectional observational case series. Consecutive patients with AMD without any other coexisting vitreoretinal disease and control patients over age 50 without AMD or any other vitreoretinal disease were imaged using Optos 200 Tx. Captured 200 degrees UWF images were corrected for peripheral geometric distortion using Optos transformation software. A newly developed grid to study perimacular and peripheral abnormalities in AMD was then projected onto the images. Results: Peripheral and perimacular changes such as drusen, retinal pigment epithelium changes and atrophy were found in patients with AMD. The presented grid in conjunction with geometric distortion-corrected UWF images allowed for systematic study of these peripheral changes in AMD. Conclusion: We present a novel grid to study peripheral and posterior pole changes in AMD. The grid is unique in that it adds a perimacular zone, which may be important in characterizing certain phenotypes in AMD. Our UWF images were corrected for geometric peripheral distortion to accurately reflect the anatomical dimensions of the retina. This grid offers a reliable and reproducible foundation for the exploration of peripheral retinal pathology associated with AMD. PMID- 29184387 TI - Lacrimal drainage anomalies in congenital rubella syndrome. AB - Purpose: The objective of this study was to ascertain the lacrimal drainage anomalies in a cohort of patients suffering from congenital rubella syndrome (CRS). Methods: This was a retrospective case series performed in patients with CRS presenting with associated lacrimal drainage anomalies (LDA) over 6 years from 2011 to 2016. All the patients were confirmed as having CRS after clinical and laboratory testing. Data collected include demographics; associated lacrimal, ocular, and systemic anomalies; interventions performed for lacrimal anomalies; and their anatomical and functional outcomes. Results: Eighty five patients were diagnosed as having CRS during the study period, and of these 23 eyes of 12 patients with associated LDA were included in the study. The prevalence of LDA was 14% in CRS. The mean age at presentation was 15.5 weeks, and all except one had bilateral presentation. Seventeen eyes were diagnosed with simple congenital nasolacrimal duct obstruction (CNLDO) and the remaining six eyes had complex CNLDO with buried probes. Additional lacrimal anomalies noted in the six complex CNLDO cases included punctal agenesis (n=3), atonic sac (n=3), incomplete punctal canalization (n=2), and single canalicular wall hypoplasia (n=1). At a mean follow-up of 12.54 months, anatomical and functional success were noted in 91.3% (21/23 eyes). Conclusion: Simple CNLDO was the most common of the LDA in CRS. Buried probe was universal among the cases with complex CNLDO. All CRS patients should be screened for lacrimal anomalies to initiate appropriate interventions for successful outcomes. PMID- 29184388 TI - Anxiety in patients undergoing cataract surgery: a pre- and postoperative comparison. AB - Purpose: Reducing surgery-related patient anxiety without under-emphasizing surgical risk is challenging for even the most experienced surgeon. The purpose of this study is to identify specific anxieties faced by patients in hopes of better informing the preoperative surgeon-patient dialogue. Setting: Comprehensive and specialty ophthalmology clinics at the University of California, San Francisco. Design: A prospective, survey-based study in which a pre- and postoperative questionnaire was administered to patients undergoing routine phacoemulsification. The surgeon was masked to patient enrollment and questionnaire responses. Materials and methods: A 36-item questionnaire on patient anxiety was developed from existing literature, building on the validated Surgical Fear Questionnaire. Patients were eligible if they were aged >18 years and willing to participate. Patients were excluded if having more than phacoemulsification alone or if unable to respond in English, and were retroactively excluded if there were complications during surgery. The primary outcome was self-reported anxiety on an 11-point Likert scale. Results: Sixty-one patients were included for analysis. Preoperatively, patients reported greatest anxiety around the operation itself and becoming blind. Reflecting postoperatively, patients reported the greatest anxiety for the operation itself. Statistically significant decreases were greatest for anxiety about the operation failing (p<0.001) and becoming blind (p<0.001). No decrease was observed for the operation itself (p=0.1). Conclusion: More effort must be made to specifically discuss the steps of the operation itself and the expected visual outcomes to alleviate patient anxiety. The authors hope these data can provide insight for surgeons into patient anxiety surrounding cataract surgery and help strengthen the patient-physician relationship.

PMID- 29184389 TI - Baracle(r) vs Baraclude(r) for 48 weeks in patients with treatment-naive chronic hepatitis B: a comparison of efficacy and safety. AB - Background and objective: Entecavir (ETV) is a standard of care for chronic hepatitis B (CHB). In a bioequivalence study, ETV from Dong-A ST (Baracle(r)) was found to have a pharmacokinetic profile equivalent to ETV from Bristol-Myers Squibb (BMS) (Baraclude(r)). The present study was conducted to evaluate the antiviral activity and safety of ETV from Dong-A ST in comparison to ETV from BMS in patients with CHB. Methods: In this multicenter, double-blind, active controlled, stratified-randomized, parallel group, comparative trial, 118 treatment-naive patients with CHB were randomly assigned to receive either 0.5 mg of ETV from Dong-A ST or ETV from BMS once daily for 48 weeks. The primary efficacy endpoint was virologic improvement (a mean reduction from baseline in serum HBV DNA levels) at 24 weeks. Secondary efficacy endpoints included a mean reduction in serum HBV DNA levels at 48 weeks, proportion of patients with undetectable levels of serum HBV DNA, rates of hepatitis B e antigen (HBeAg) loss and seroconversion, rates of HBsAg loss and seroconversion, and rates of normalization of alanine aminotransferase (ALT) levels. Results: From baseline to week 24, HBV DNA levels (log10) decreased by 4.81 and 4.63 with ETV from Dong-A ST and with ETV from BMS, respectively. The upper limit of two-sided 95% confidence intervals (CI) (equivalent to one-sided 97.5% CIs) for the difference between the treatment groups was 0.208, which was below the noninferiority margin of 1, thus supporting the noninferiority of ETV from Dong-A ST in comparison to ETV from BMS. No statistically significant differences were noted between the treatment groups in all secondary and tertiary efficacy endpoints. Safety profiles were also similar between the two groups. Conclusion: In patients with previously untreated HBeAg-positive or negative HBV infection, the efficacy of ETV from Dong-A ST was noninferior to that of ETV from BMS, and there were no significant differences in efficacy or safety between two groups.

In the last few years, peptide drugs have become attractive agents in cancer therapy. HM-3, mainly with antiangiogenic effect, and AP25, with an additional antiproliferative effect, are two peptides designed in our laboratory targeting alphavbeta3 and alpha5beta1 integrins, respectively. The low molecular weight of the two peptides renders their recombinant expression very difficult, and the complicated structure of AP25 makes its chemical synthesis restricted, which presents a big challenge for its development. Methods: Bifunctional peptides designed by the ligation of HM-3 and AP25, using linkers with different flexibility, were prepared using recombinant DNA technology in Escherichia coli. The fusion peptides were expressed in a modified auto-induction medium based on a mixture of glucose, glycerol, and lactose as carbon substrates and NH4+ as nitrogen source without any amino acid or other elements. Subsequently, the antiangiogenic, antiproliferative, and cell adhesion assays were conducted to evaluate the bioactivity of the two fusion peptides. Results: The peptides were successfully expressed in a soluble form without any induction, which allows the culture to reach higher cell density before protein expression occurs. Human umbilical vein endothelial cell migration assay and chick embryo chorioallantoic membrane assay showed, at low doses, a significantly increased antiangiogenic effect (>75%) of the purified products compared with the single molecules. Meanwhile, MTT assay confirmed their enhanced antitumor activity against gastric cancer cell line MGC 803; however, no significant effect was observed on hepatoma HepG2 cells and no cytotoxicity on normal human lens epithelial cell SRA01/04 and human epithelial esophageal cells. Conclusion: Bifunctional molecules with antiangiogenic and antiproliferative effects were obtained by using this technique, which presents an alternative for small peptide production, instead of the conventional chemical method. The increased molecular weight facilitates the peptide expression with a simultaneous improvement in their stability and biological activity.

AB - Toll-like receptors (TLRs) may be involved in diabetic nephropathy (DN). Paeoniflorin (PF) is an effective Chinese traditional medicine with anti inflammatory and immunoregulatory effects that may inhibit the TLR2 signaling pathway. In this study, we investigated the effects of PF on the kidneys of mice with streptozotocin-induced type 1 diabetes mellitus using TLR2 knockout mice (TLR2-/-) and wild-type littermates (C57BL/6J-WT). After 12 weeks of intraperitoneal injection of PF at doses of 25, 50, and 100 mg/kg once a day, diabetic mice had significantly reduced albuminuria and attenuated renal histopathology. These changes were associated with substantially alleviated macrophage infiltration and decreased expression of TLR2 signaling pathway biomarkers. These data support a role of TLR2 in promoting inflammation and indicate that the effect of PF is associated with the inhibition of the TLR2 pathway in the kidneys of diabetic mice. PF thus shows therapeutic potential for the prevention and treatment of DN. PMID- 29184393 TI - Recovery in patients with major depressive disorder (MDD): results of a 6-month, multinational, observational study. AB - Not all individuals treated for major depressive disorder (MDD) achieve recovery. This observational study examined the recovery rates in MDD patients and the patient characteristics associated with achieving recovery in a naturalistic clinical setting. Recovery was defined as having both clinical and functional remission. Data for this post hoc analysis were taken from a 24-week prospective, observational study that involved 1,549 MDD patients. Clinical remission was assessed using the 16-item Quick Inventory of Depressive Symptomatology Self Report and functional remission through the Sheehan Disability Scale and no days of reduced productivity in the previous week. Generalized estimating equation regression models were used to examine the baseline factors associated with recovery during follow-up. Clinical and functional remission was achieved in 70.6% and 56.1% of the MDD patients, respectively. MDD patients who achieved recovery (52.1%) were significantly less likely to have impaired levels of functioning, concurrent medical or psychiatric conditions, low levels of education, or nonadherence to therapy at follow-up. The level of functioning during the index episode seems to be a better predictor of recovery than symptom severity. Therefore, the level of functioning should be considered while determining recovery from depression. PMID- 29184394 TI - Highly specific reasons for nonadherence to antiretroviral therapy: results from the German adherence study. AB - Background: Reasons for and frequency of nonadherence to antiretroviral therapy (ART) may have changed due to pharmacological improvements. In addition, the importance of known non-pharmacologic reasons for nonadherence is unclear. Methods: We performed a cross-sectional, noninterventional, multicenter study to identify current reasons for nonadherence. Patients were categorized by physicians into the following adherence groups: good, unstable, or poor adherence. Co-variables of interest included age, sex, time since HIV diagnosis, ART duration, current ART regimen, HIV transmission route, comorbidity, HIV-1 RNA viral load (VL), and CD4 cell count. Patients self-reported the number of missed doses and provided their specific reasons for nonadherent behavior. Statistical analyses were performed using Fisher's extended exact test, Kruskal-Wallis test, and logistic regression models. Results: Our study assessed 215 participants with good (n=162), unstable (n=36), and poor adherence (n=17). Compared to patients with good adherence, patients with unstable and poor adherence reported more often to have missed at least one dose during the last week (good 11% vs unstable 47% vs poor 63%, p<0.001). Physicians' adherence assessment was concordant with patients' self-reports of missed doses during the last week (no vs one or more) in 81% cases. Similarly, we found a strong association of physicians' assessment with viral suppression. Logistic regression analysis showed that "reduced adherence" - defined as unstable or poor - was significantly associated with patients <30 years old, intravenous drug use, history of acquired immune deficiency syndrome (AIDS), and psychiatric disorders (p<0.05). Univariate analyses showed that specific reasons, such as questioning the efficacy/dosing of ART, HIV stigma, interactive toxicity beliefs regarding alcohol and/or party drugs, and dissatisfaction with regimen complexity, correlated with unstable or poor adherence (p<0.05). Conclusion: Identification of factors associated with poor adherence helps in identifying patients with a higher risk for nonadherence. Reasons for nonadherence should be directly addressed in every patient, because they are common and constitute possible adherence intervention points. PMID- 29184396 TI - Excessive anterior cervical muscle tone affects hyoid bone kinetics during swallowing in adults. AB - Purpose: This study aimed to determine whether excessive neck muscle tone affects hyoid bone kinetics during swallowing using videofluorography (VF) in an unnatural posture in adults. Subjects and methods: Subjects were 28 adults (12 men, 16 women; mean age, 39.75+/-9.50 years) who were suspected to have some symptom of swallowing disorders but did not have swallowing dysfunctional from the result of videofluorography. We first established the participant's posture a reclining wheelchair that was adjusted to a 30-degree angle with the headrest (without excessive neck muscle tone) or without headrest (with excessive neck muscle tone), used an electromyogram above the mylohyoid muscle to represent the suprahyoid muscles and above the sternohyoid muscle to represent the infrahyoid muscles to confirm neck muscle tone, and then conducted VF of swallowing measurements. Videofluorographic images were obtained when 5 mL of 50% (w/v) barium sulfate was being swallowed, and hyoid bone coordinate (the resting position and the elevated position), extent of horizontal and vertical hyoid bone elevation, as well as duration and velocity of hyoid bone elevation were evaluated (x-axis and y-axis coordinates for the resting position of hyoid bone are referred to as Xr and Yr, respectively; those for the elevated hyoid bone position induced during swallowing are referred to as Xs and Ys, respectively). Results: In the resting position of the hyoid bone, the Yr coordinates in those with excessive neck muscle tone were significantly lower than in those without excessive neck muscle tone. Vertical hyoid bone elevation and hyoid bone elevation velocity were significantly higher with excessive neck muscle tone than without excessive neck muscle tone, whereas horizontal elevation showed no significant differences. Conclusion: Our findings suggest that the generation of neck muscle tone due to inappropriate posture may encourage hyoid depression and increase the extent of hyoid bone elevation, thereby increasing the risk of aspiration. PMID- 29184397 TI - Do older drivers with bilateral cataract self-regulate their driving while waiting for first eye cataract surgery? AB - Objectives: To analyze the association between visual impairment and driver self regulation among a cohort of older drivers waiting for first eye cataract surgery. Methods: Ninety-six drivers with bilateral cataract aged 55+ years were assessed before first eye cataract surgery. Data collection consisted of a researcher-administered questionnaire, objective visual measures (visual acuity, contrast sensitivity and stereopsis), a visual attention test (the useful field of view test) and a cognitive test (the Mini-Mental State Examination). Driver self-regulation practices were collected using the Driving Habits Questionnaire and were also measured with an in-vehicle monitoring device. Characteristics of self-regulators and non-self-regulators were compared and a logistic regression model was used to examine the association between 3 objective visual measures and driver self-regulation status. Results: After controlling for potential confounding factors, only binocular contrast sensitivity (p=0.01), age (p=0.03) and gender (p=0.03) were significantly associated with driver self-regulation status. The odds of participants with better contrast sensitivity scores (better vision) self-regulating their driving in at least 1 driving situation decreased (odds ratio [OR]: 0.01, 95% CI: 0.00-0.28) while those of increasing age reported an increased odds of self-regulating their driving (OR: 1.08, 95% CI: 1.01-1.15). The odds of males self-regulating their driving was decreased compared with females (OR: 0.28, 95% CI: 0.09-0.86). Conclusions: Worse binocular contrast sensitivity scores, increasing age and being female were significantly associated with driver self-regulation. The study highlighted that while self-regulation was common among cataract patients, a proportion of those with poor vision did not self-regulate. Further research should determine how cataract patients could benefit from self-regulation strategies while waiting for cataract surgery. PMID- 29184395 TI - Does eating less make you live longer and better? An update on calorie restriction. AB - The complexity of aging is hard to be captured. However, apart from its tissue specific features, a structural and functional progressive decline of the whole organism that leads to death, often preceded by a phase of chronic morbidity, characterizes the common process of aging. Therefore, the research goal of scientists in the field moved from the search for strategies able to extend longevity to those ensuring healthy aging associated with a longer lifespan referred to as "healthspan". The aging process is plastic and can be tuned by multiple mechanisms including dietary and genetic interventions. To date, the most robust approach, efficient in warding off the cellular markers of aging, is calorie restriction (CR). Here, after a preliminary presentation of the major debate originated by CR, we concisely overviewed the recent results of CR treatment on humans. We also provided an update on the molecular mechanisms involved by CR and the effects on some of the age-associated cellular markers. We finally reviewed a number of tested CR mimetics and concluded with an evaluation of future applications of such dietary approach. PMID- 29184398 TI - The role of pain in pulmonary rehabilitation: a qualitative study. AB - Introduction: One third of individuals with chronic obstructive pulmonary disease (COPD) report pain. To help inform a COPD-specific pain intervention, we explored the views of health care providers (HCPs) and individuals with COPD on pain during pulmonary rehabilitation (PR). Methods: This is a qualitative study using inductive thematic analysis. Eighteen HCPs familiar with PR and 19 patients enrolled in PR participated in semi-structured interviews. Demographic data were recorded, and the patients completed the Brief Pain Inventory (Short Form). Results: 1) Interaction between pain and COPD: pain is a common experience in COPD, heightened by breathlessness and anxiety. 2) Pain interfering with PR: a) Communicating pain: HCPs rarely ask about pain and patients are reluctant to report it for fear of being removed from PR. b) PR is a short-term aggravator but long-term reliever: although pain limits exercise, concentration, and program adherence, PR may reduce pain by increasing muscle strength and improving coping. c) Advice and strategies for pain: some attention is given to pain management but this is often counterproductive, encouraging patients to cease exercise. 3) An intervention to manage pain: HCPs were enthusiastic about delivering a pain intervention within their knowledge and time constraints. Early group education was preferred. Conclusion: A pain intervention seems warranted in PR and may improve adherence and therefore clinical benefit. A pain intervention could be provided as part of PR education with HCP training. PMID- 29184399 TI - Application of a lipid-coated hollow calcium phosphate nanoparticle in synergistic co-delivery of doxorubicin and paclitaxel for the treatment of human lung cancer A549 cells. AB - In this study, we developed a lipid-coated hollow calcium phosphate (LCP) nanoparticle for the combined application of two chemotherapeutic drugs to human lung cancer A549 cells. Hydrophilic doxorubicin (DOX) was incorporated into the hollow structure of hollow calcium phosphate (HCP), and a lipid bilayer containing hydrophobic paclitaxel (PTX) was subsequently coated on the surface of HCP. The study on combinational effects demonstrated that the combination of DOX and PTX at a mass ratio of 12:1 showed a synergistic effect against A549 cells. The particle size, zeta potential, and encapsulation efficiency were measured to obtain optimal values: particle size was 335.0 3.2 nm, zeta potential -41.1 mV, and encapsulation efficiency 80.40%+/-2.24%. An in vitro release study indicated that LCP produced a sustained drug release. A549 cells had a better uptake of LCP with good biocompatibility. Furthermore, in vitro cytotoxicity experiment, apoptosis analysis, in vivo anti-tumor efficacy and protein expression analysis of Bax, Bcl-2, and Caspase-3 demonstrated that the co-delivery system based on LCP had significant synergistic anti-tumor activity. All conclusions suggested that LCP is a promising platform for co-delivery of multiple anti-tumor drugs. PMID- 29184400 TI - Drug delivery to solid tumors: the predictive value of the multicellular tumor spheroid model for nanomedicine screening. AB - The increasing number of publications on the subject shows that nanomedicine is an attractive field for investigations aiming to considerably improve anticancer chemotherapy. Based on selective tumor targeting while sparing healthy tissue, carrier-mediated drug delivery has been expected to provide significant benefits to patients. However, despite reduced systemic toxicity, most nanodrugs approved for clinical use have been less effective than previously anticipated. The gap between experimental results and clinical outcomes demonstrates the necessity to perform comprehensive drug screening by using powerful preclinical models. In this context, in vitro three-dimensional models can provide key information on drug behavior inside the tumor tissue. The multicellular tumor spheroid (MCTS) model closely mimics a small avascular tumor with the presence of proliferative cells surrounding quiescent cells and a necrotic core. Oxygen, pH and nutrient gradients are similar to those of solid tumor. Furthermore, extracellular matrix (ECM) components and stromal cells can be embedded in the most sophisticated spheroid design. All these elements together with the physicochemical properties of nanoparticles (NPs) play a key role in drug transport, and therefore, the MCTS model is appropriate to assess the ability of NP to penetrate the tumor tissue. This review presents recent developments in MCTS models for a better comprehension of the interactions between NPs and tumor components that affect tumor drug delivery. MCTS is particularly suitable for the high-throughput screening of new nanodrugs. PMID- 29184401 TI - Placenta-derived exosomes: potential biomarkers of preeclampsia. AB - Preeclampsia remains a leading cause of maternal and fetal mortality, due to ineffective treatment and diagnostic strategies, compounded by the lack of clarity on the etiology of the disorder. Although several clinical and biological markers of preeclampsia have been evaluated, they have proven to be ineffective in providing a definitive diagnosis during the various stages of the disorder. Exosomes have emerged as ideal biomarkers of pathological states, such as cancer, and have more recently gained interest in pregnancy-related complications, due to their role in cellular communication in normal and complicated pregnancies. This occurs as a result of the specific placenta-derived exosomal molecular cargo, which may be involved in normal pregnancy-associated immunological events, such as the maintenance of maternal-fetal tolerance. This review provides perspectives on placenta-derived exosomes as possible biomarkers for the diagnosis/prognosis of preeclampsia. Using keywords, online databases were searched to identify relevant publications to review the potential use of placenta-derived exosomes as biomarkers of preeclampsia. PMID- 29184402 TI - Cooperation of IRAK1/4 inhibitor and ABT-737 in nanoparticles for synergistic therapy of T cell acute lymphoblastic leukemia. AB - T cell acute lymphoblastic leukemia (T-ALL) is caused by clonal expansion of variant T cell progenitors and is considered as a high risk leukemia. Contemporary single chemotherapy has a limited effect due to dynamic and versatile properties of T-ALL. Here IRAK1/4 inhibitor and ABT-737 were co encapsulated into polyethylene glycol modified poly (lactic-co-glycolic acid) nanoparticles (IRAK/ABT-NP) to enhance synergistic therapy of T-ALL. The formulation was optimized to achieve high drug loading using Box-Behnken design and response surface methodology. The optimal parameter comprised 2.98% polymer in acetonitrile, a ratio of oil phase to water phase of 1:8.33, and 2.12% emulsifier concentration. High drug loading and uniform spherical shape was achieved. In vitro release study showed sustained release of IRAK1/4 inhibitor for 72 hours as well as sustained release of ABT-737 for more than 120 hours. Uptake efficiency of IRAK/ABT-NP and induced apoptotic T-ALL fraction by IRAK/ABT NP were much higher than the IRAK1/4 and ABT-737 combined solution. IC50 of IRAK/ABT-NP was two-fold lower than free drug combination in Jurkat cells. Additionally, we conducted in vivo experiments in which IRAK/ABT-NP exhibited greater cytotoxicity toward T-ALL cells, the capacity to significantly restore white blood cell number in peripheral blood, and improved survival time of T-ALL mouse model compared to the IRAK1/4 and ABT-737 combined solution. PMID- 29184403 TI - Confocal laser scanning microscopy to estimate nanoparticles' human skin penetration in vitro. AB - Objective: With rapid development of nanotechnology, there is increasing interest in nanoparticle (NP) application and its safety and efficacy on human skin. In this study, we utilized confocal laser scanning microscopy to estimate NP skin penetration. Methods: Three different-sized polystyrene NPs marked with red fluorescence were applied to human skin, and Calcium Green 5N was used as a counterstain. Dimethyl sulfoxide (DMSO) and ethanol were used as alternative vehicles for NPs. Tape stripping was utilized as a barrier-damaged skin model. Skin biopsies dosed with NPs were incubated at 4 degrees C or 37 degrees C for 24 hours and imaged using confocal laser scanning microscopy. Results: NPs were localized in the stratum corneum (SC) and hair follicles without penetrating the epidermis/dermis. Barrier alteration with tape stripping and change in incubation temperature did not induce deeper penetration. DMSO enhanced NP SC penetration but ethanol did not. Conclusion: Except with DMSO vehicle, these hydrolyzed polystyrene NPs did not penetrate intact or barrier-damaged human "viable" epidermis. For further clinical relevance, in vivo human skin studies and more sensitive analytic chemical methodology are suggested. PMID- 29184404 TI - Autophagic flux induced by graphene oxide has a neuroprotective effect against human prion protein fragments. AB - Graphene oxide (GO) is a nanomaterial with newly developing biological applications. Autophagy is an intracellular degradation system that has been associated with the progression of neurodegenerative disorders. Although induction of autophagic flux by GO has been reported, the underlying signaling pathway in neurodegenerative disorders and how this is involved in neuroprotection remain obscure. We show that GO itself activates autophagic flux in neuronal cells and confers a neuroprotective effect against prion protein (PrP) (106-126)-mediated neurotoxicity. GO can be detected in SK-N-SH neuronal cells, where it triggers autophagic flux signaling. GO-induced autophagic flux prevented PrP (106-126)-induced neurotoxicity in SK-N-SH cells. Moreover, inactivation of autophagic flux blocked GO-induced neuroprotection against prion mediated mitochondrial neurotoxicity. This is the first study to demonstrate that GO regulates autophagic flux in neuronal cells, and that activation of autophagic flux signals, induced by GO, plays a neuroprotective role against prion-mediated mitochondrial neurotoxicity. These results suggest that the nanomaterial GO may be used to activate autophagic flux and could be used in neuroprotective strategies for treatment of neurodegenerative disorders, including prion diseases. PMID- 29184405 TI - Absence of lung fibrosis after a single pulmonary delivery of lipid nanocapsules in rats. AB - Lipid nanocapsules (LNCs) are potential drug carriers for pulmonary delivery since they can be nebulized without any structural or functional changes, and the aerosols produced are highly compatible with pulmonary drug delivery in human beings. The alveolar surface tension, in vitro cytotoxicity, biodistribution and pulmonary toxicity in rats of a single endotracheal spray of LNCs or paclitaxel loaded LNCs were studied. In vitro cytotoxicity of LNCs after a spray remained unchanged. Biodistribution study showed a homogeneous repartition in the lungs in rats with an improvement in lung retention of the radiolabeled tracer loaded in LNCs compared to the absence of LNCs with a lung half-time of 8.8+/-0.7 hours. Bronchoalveolar fluid analysis revealed transient 7-day alveolar inflammation, reaching a maximum between days 2 and 4, characterized by a peak of granulocytes at day 1 followed by a peak of lymphocytes at day 3. Alveolar protein levels were increased at days 3 and 7. Acute inflammation was increased with paclitaxel loaded LNCs in comparison with blank LNCs but dropped out at day 7. No histological pulmonary lesion was observed at day 60. LNCs lowered surface tension to a greater degree than Curosurf(r) in a physicochemical model of the pulmonary alveolus. A single pulmonary delivery of LNCs induces a short-term alveolar inflammation with no residual lesions in rats at day 60. These data permit to start the study of LNCs in surfactant replacement therapy. PMID- 29184406 TI - Effect of A-317491 delivered by glycolipid-like polymer micelles on endometriosis pain. AB - Endometriosis is a common gynecological disease with a lack of effective clinical treatment. Current therapy often results in endometriosis pain recurrence and serious side effects. P2X3 receptor, an adenosine triphosphate (ATP)-gated ion channel, might be implicated in endometriosis pain. In this study, chitosan oligosaccharide-g-stearic acid (CSOSA) polymer micelles-coated nanostructured lipid carriers (NLCs) were developed as a novel delivery system for A-317491, a selective P2X3 receptor antagonist for endometriosis pain therapy. A-317491 loaded NLC (NLC/A-317491) could be coated by CSOSA micelles to form CSOSA/NLC/A 317491 nanoparticles. Pheochromocytoma PC12 cells, which highly expressed P2X3 receptors, were used as a cell model, and the CSOSA/NLC/A-317491 partly blocked the Ca2+ influx induced by ATP stimulation. In nude mouse and rat endometriotic models, CSOSA/NLC could accumulate into endometriotic lesions after vein injection. In endometriotic rats, CSOSA/NLC/A-317491 reversed mechanical and heat hyperalgesia with long-term efficacy, which might be attributed to the massive CSOSA/NLC/A-317491 distribution in the endometriotic lesions. In conclusion, A 317491 delivered by CSOSA/NLC nanoparticles attenuated endometriosis pain in rats, and CSOSA/NLC/A-317491 could be used as an effective treatment strategy for P2X3-targeted therapy in endometriosis pain. PMID- 29184407 TI - Photodynamic therapy by conjugation of cell-penetrating peptide with fluorochrome. AB - Photodynamic therapy (PDT) is a promising alternative therapy that could be used as an adjunct to chemotherapy and surgery for cancer, and works by destroying tissue with visible light in the presence of a photosensitizer (PS) and oxygen. The PS should restrict tissue destruction only to the tumor and be activated by light of a specific wavelength; both of these properties are required. Arginine rich peptides, such as cell-penetrating peptides, have membrane-translocating and nuclear-localizing activities, which have led to their application in various drug delivery modalities. Protamine (Pro) is an arginine-rich peptide with membrane-translocating and nuclear-localizing properties. The reaction of an N hydroxysuccinimide (NHS) ester of rhodamine (Rho) and clinical Pro was carried out in this study to yield RhoPro, and a demonstration of its phototoxicity, wherein clinical Pro improved the effect of PDT, was performed. The reaction between Pro and the NHS ester of Rho is a solution-phase reaction that results in the complete modification of the Pro peptides, which feature a single reactive amine at the N-terminal proline and a single carboxyl group at the C-terminal arginine. This study aimed to identify a new type of PS for PDT by in vitro and in vivo experiments and to assess the antitumor effects of PDT, using the Pro conjugated PS, on a cancer cell line. Photodynamic cell death studies showed that the RhoPro produced has more efficient photodynamic activities than Rho alone, causing rapid light-induced cell death. The attachment of clinical Pro to Rho, yielding RhoPro, confers the membrane-internalizing activity of its arginine-rich content on the fluorochrome Rho and can induce rapid photodynamic cell death, presumably owing to light-induced cell membrane rupture. PDT using RhoPro for HT 29 cells was very effective and these findings suggest that RhoPro is a suitable candidate as a PS for solid tumors. PMID- 29184408 TI - Size-controlled fabrication of zein nano/microparticles by modified anti-solvent precipitation with/without sodium caseinate. AB - Zein-based nano/microparticles have been demonstrated to be promising carrier systems for both the food industry and biomedical applications. However, the fabrication of size-controlled zein particles has been a challenging issue. In this study, a modified anti-solvent precipitation method was developed, and the effects of various factors, such as mixing method, solvent/anti-solvent ratio, temperature, zein concentrations and the presence of sodium caseinate (SC) on properties of zein particles were investigated. Evidence is presented that, among the previously mentioned factors, the mixing method, especially mixing rate, could be used as an effective parameter to control the size of zein particles without changing other parameters. Moreover, through fine-tuning the mixing rate together with zein concentration, particles with sizes ranging from nanometers to micrometers and low polydispersity index values could be easily obtained. Based on the size-controlled fabrication method, SC-coated zein nanoparticles could also be obtained in a size-controlled manner by incubation of the coating material with the already-formed zein particles. The resultant nanoparticles showed better performance in both drug loading and controlled release, compared with zein/SC hybrid nanoparticles fabricated by adding aqueous ethanol solution to SC solution. The possible mechanisms of the nanoprecipitation process and self assembly formation of these nanoparticles are discussed. PMID- 29184409 TI - Nanomaterials for alternative antibacterial therapy. AB - Despite an array of cogent antibiotics, bacterial infections, notably those produced by nosocomial pathogens, still remain a leading factor of morbidity and mortality around the globe. They target the severely ill, hospitalized and immunocompromised patients with incapacitated immune system, who are prone to infections. The choice of antimicrobial therapy is largely empirical and not devoid of toxicity, hypersensitivity, teratogenicity and/or mutagenicity. The emergence of multidrug-resistant bacteria further intensifies the clinical predicament as it directly impacts public health due to diminished potency of current antibiotics. In addition, there is an escalating concern with respect to biofilm-associated infections that are refractory to the presently available antimicrobial armory, leaving almost no therapeutic option. Hence, there is a dire need to develop alternate antibacterial agents. The past decade has witnessed a substantial upsurge in the global use of nanomedicines as innovative tools for combating the high rates of antimicrobial resistance. Antibacterial activity of metal and metal oxide nanoparticles (NPs) has been extensively reported. The microbes are eliminated either by microbicidal effects of the NPs, such as release of free metal ions culminating in cell membrane damage, DNA interactions or free radical generation, or by microbiostatic effects coupled with killing potentiated by the host's immune system. This review encompasses the magnitude of multidrug resistance in nosocomial infections, bacterial evasion of the host immune system, mechanisms used by bacteria to develop drug resistance and the use of nanomaterials based on metals to overcome these challenges. The diverse annihilative effects of conventional and biogenic metal NPs for antibacterial activity are also discussed. The use of polymer-based nanomaterials and nanocomposites, alone or functionalized with ligands, antibodies or antibiotics, as alternative antimicrobial agents for treating severe bacterial infections is also discussed. Combinatorial therapy with metallic NPs, as adjunct to the existing antibiotics, may aid to restrain the mounting menace of bacterial resistance and nosocomial threat. PMID- 29184411 TI - Depression, anxiety, stress, and their associated factors among Jimma University staff, Jimma, Southwest Ethiopia, 2016: a cross-sectional study. AB - Background: Worldwide, approximately 450 million people suffer from mental disorders. Of these, approximately 150 million are affected with depression. Depression, anxiety, and stress have an impact on productivity, motivation to work, sleep behavior of the individual, and outcome of different chronic diseases. However, till date, there are no studies which evaluated mental health problems among university staff in Ethiopia. Therefore, in this study, we aimed to assess the prevalence of depression, anxiety, stress, and their associated factors among Jimma University staff. Methods: An institution-based cross sectional study was conducted among 354 staff of Jimma University from March 24 to April 24, 2016. Stratified simple random sampling technique was used. Pretested interviewer-administered Depression, Anxiety and Stress Scale (DASS-21) questionnaire was used to collect the data. Data were analyzed using SPSS Version 20.0 software. Results: The prevalence of depression, anxiety, and stress in this study was found to be approximately 22.9%, 19.2%, and 28.2%, respectively. Being female (adjusted odds ratio [AOR] =2.43, 95% confidence interval [CI] =1.22 4.77), no job satisfaction (AOR =10.59, 95% CI =4.88-22.98), presence of conflict with colleagues (AOR =2.33, 95% CI =1.21-4.49), and khat chewing (AOR =4.99, 95% CI =2.57-9.69) were associated with depression. Presence of conflict with colleagues (AOR =2.46, 95% CI =1.25-4.85), no job satisfaction (AOR =7.12, 95% CI =3.29-15.45), and khat chewing (AOR =2.94, 95% CI =1.52-5.66) were associated with anxiety. Being widowed (AOR =7.46, 95% CI =1.11-50.15), female (AOR =2.72, 95% CI =1.40-5.28), no job satisfaction (AOR =6.69, 95% CI =3.46-12.97), khat chewing (AOR =2.78, 95% CI =1.49-5.21), and presence of conflict with colleagues (AOR =2.93, 95% CI =1.57-5.46) were associated with stress. Conclusion: The burden of depression, anxiety, and stress among Jimma University staff was found to be high. Being female, widowed, or khat chewer or having a history of conflict with colleagues and no job satisfaction were predictors of depression, anxiety, and stress. Therefore, it is recommended to design preventive strategies to reduce the risk of these problems and to minimize the disease burden. PMID- 29184410 TI - Anti-MRSA malleable liposomes carrying chloramphenicol for ameliorating hair follicle targeting. AB - Pathogens usually invade hair follicles when skin infection occurs. The accumulated bacteria in follicles are difficult to eradicate. The present study aimed to assess the cutaneous and follicular delivery of chloramphenicol (Cm) loaded liposomes and the antibacterial activity of these liposomes against methicillin-resistant Staphylococcus aureus (MRSA). Skin permeation was conducted by in vitro Franz diffusion cell. The anti-MRSA potential was checked using minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), a well diffusion test, and intracellular MRSA killing. The classic, dimyristoylphosphatidylcholine (DMPC), and deoxycholic acid (DA) liposomes had a vesicle size of 98, 132, and 239 nm, respectively. The incorporation of DMPC or DA into the liposomes increased the bilayer fluidity. The malleable vesicles containing DMPC and DA showed increased follicular Cm uptake over the control solution by 1.5- and 2-fold, respectively. The MIC and MBC of DA liposomes loaded with Cm were 62.5 and 62.5-125 MUg/mL, comparable to free Cm. An inhibition zone about 2-fold higher was achieved by DA liposomes as compared to the free control at a Cm dose of 0.5 mg/mL. DA liposomes also augmented antibacterial activity on keratinocyte-infected MRSA. The deformable liposomes had good biocompatibility against keratinocytes and neutrophils (viability >80%). In vivo administration demonstrated that DA liposomes caused negligible toxicity on the skin, based on physiological examination and histology. These data suggest the potential application of malleable liposomes for follicular targeting and the treatment of MRSA-infected dermatologic conditions. PMID- 29184412 TI - A 6-year study of complicated urinary tract infections in southern China: prevalence, antibiotic resistance, clinical and economic outcomes. AB - Urinary tract infections (UTIs) are common nosocomial infections. This study evaluated the prevalence, pathogens, antibiotic resistances, clinical outcomes, and hospitalization costs associated with complicated UTIs in southern China, and risk factors delaying patient discharge. We retrospectively reviewed electronic medical records of 4,284 (61.4% women) complicated UTI-related hospitalizations from 2008 to 2013. Average patient age was 61.1 years and median hospital stay was 11 days. Pathogens were isolated from 1,071 urine and 148 blood specimens. Gram-negative bacteria were the most frequent and included Escherichia coli (48.2%), Klebsiella pneumoniae (9.5%), Pseudomonas aeruginosa (4.9%), and Proteus mirabilis (4.6%), while Enterococcus spp. (14.4%) was the most common Gram positive bacteria causing UTIs. Both E. coli and K. pneumoniae showed high resistance rates (>45%) to wide-spectrum penicillins, cephalosporins, aztreonam, and ciprofloxacin. Resistances to beta-lactamase inhibitor/beta-lactam antibiotic combination were relatively lower. Imipenem, meropenem, and amikacin had the greatest activity against E.coli and K. pneumoniae. Recurrent infection was a risk factor for mortality. Age, sex, previous surgery, diabetes, and renal insufficiency were significant risk factors for delayed discharge (P<0.01). Response to initial treatment was associated with a lower cost. Initial empiric use of antibiotics least associated with resistance may reduce costs and medical resource usage. PMID- 29184413 TI - Near-fatal asthma responsive to mepolizumab after failure of omalizumab and bronchial thermoplasty. AB - Severe asthma affects between 5% and 10% of patients with asthma worldwide and requires best standard therapies at maximal doses, but there is a subgroup of patients refractory to all treatments. We share a case report of a 53-year-old woman with a history of severe allergic asthma that progressively worsened over the years despite the best therapy. She had been hospitalized 35 times, including nine admissions to the respiratory intensive care unit due to severe exacerbations. To rule out other possible diagnoses, several investigations were performed, such as computed tomography scan of the chest and neck, fiberoptic laryngoscopy, antineutrophil cytoplasmic antibodies, and complete blood cell count. The patient was first treated with omalizumab, which was completely ineffective, and then with bronchial thermoplasty (BT), again without clinical benefit. The situation remained critical for about 3 months during the last hospitalization, but in February 2017, the Italian Medicines Agency approved the treatment of severe refractory eosinophilic asthma with mepolizumab (Nucala(r)). Given a blood eosinophil count of 300 cells/MUL, our patient was started on 100 mg mepolizumab treatment. After the second administration, symptoms improved progressively, with a reduction in the number and severity of exacerbations, so the patient could finally be discharged from hospital. At follow-up, it was possible to reduce and then suspend oral corticosteroids by continuing only with inhaled corticosteroids/long-acting beta-agonists and montelukast. No further asthmatic exacerbations occurred; symptom control and quality of life improved significantly. To our knowledge, this is the first case of a patient unresponsive to omalizumab and BT but with excellent clinical response to mepolizumab. She is also the first patient to be treated with an anti-IL5 agent in Italy in a real life clinical setting. The availability of new effective biological agents will allow many patients to resume as normal a life as possible, with a positive outcome also from a social and economic point of view.

PMID- 29184415 TI - Reversible preoperative renal dysfunction does not add to the risk of postoperative acute kidney injury after cardiac valve surgery. AB - Objective: To evaluate the impact of the renal dysfunction (RD) type and change of postoperative cardiac function on the risk of developing acute kidney injury (AKI) in patients who underwent cardiac valve surgery. Method: Reversible renal dysfunction (RRD) was defined as preoperative RD in patients who had not been initially diagnosed with chronic kidney disease (CKD). Cardiac function improvement (CFI) was defined as postoperative left ventricular ejection function - preoperative left ventricular ejection function (DeltaEF) >0%, and cardiac function not improved (CFNI) as DeltaEF <=0%. Results: Of the 4,805 (94%) cardiac valve surgery patients, 301 (6%) were RD cases. The AKI incidence in the RRD group (n=252) was significantly lower than in the CKD group (n=49) (36.5% vs 63.3%, P=0.018). The AKI and renal replacement therapy incidences in the CFI group (n=174) were significantly lower than in the CFNI group (n=127) (33.9% vs 50.4%, P=0.004; 6.3% vs 13.4%, P=0.037). After adjustment for age, gender, and other confounding factors, CKD and CKD + CFNI were identified as independent risk factors for AKI in all patients after cardiac valve surgery. Multivariate logistic regression analysis showed that the risk factors for postoperative AKI in preoperative RD patients were age, gender (male), hypertension, diabetes, chronic heart failure, cardiopulmonary bypass time (every 1 min added), and intraoperative hypotension, while CFI after surgery could reduce the risk. Conclusion: For cardiac valve surgery patients, preoperative CKD was an independent risk factor for postoperative AKI, but RRD did not add to the risk. Improved postoperative cardiac function can significantly reduce the risk of postoperative AKI. PMID- 29184417 TI - Primary site surgery for metastatic adrenocortical carcinoma improves survival outcomes: an analysis of a population-based database. AB - Objective: To define the survival effect of surgery of primary adrenal malignant lesions in metastatic adrenocortical carcinoma (ACC) patients. Patients and methods: We used the Surveillance, Epidemiology and End Results (SEER) database (1973-2014) to identify metastatic ACC patients (stage IV by using European Network for the Study of Adrenal Tumors stage classification). Correlated variables, including age, sex, race, tumor laterality, treatment modality, lymph node dissection, surgery of metastatic site, tumor size, and tumor stage, were extracted. Univariate and multivariate Cox regression analyses were used to define the efficacy of surgery on survival outcomes, including overall survival and cancer-specific survival of ACC. Results: There were 290 metastatic ACC patients identified from the database. The overall median survival time was 7 (95% CI, 6-8) months. Among these patients, 118 patients received primary site surgery and 172 patients did not. In both univariate and multivariate analyses, primary site surgery significantly improved both overall (hazard ratio 0.413, 95% CI, 0.299-0.571, P<0.01) and cancer-specific survival (hazard ratio 0.408, 95% CI, 0.290-0.574, P<0.01) for metastatic ACC patients. Conclusion: Our study suggests that primary site surgery in metastatic ACC patients significantly improved overall and cancer-specific survival. Further multicenter prospective studies are still needed to validate these outcomes. PMID- 29184416 TI - Variations in patient safety climate and perceived quality of collaboration between professions in out-of-hours care. AB - Purpose: To get an overview of health care workers perceptions of patient safety climates and the quality of collaboration in Slovenian out-of-hours health care (OOHC) between professional groups. Materials and methods: This was a cross sectional study carried out in all (60) Slovenian OOHC clinics; 37 (61.7%) agreed to participate with 438 employees. The questionnaire consisted of the Slovenian version of the Safety Attitudes Questionnaire - Ambulatory Version (SAQ-AV). Results: The study sample consisted of 175 (70.0%) physicians, nurse practitioners, and practice nurses. Practice nurses reported the highest patient safety climate scores in all dimensions. Total mean (standard deviation) SAQ-AV score was 60.9+/-15.2. Scores for quality of collaboration between different professional groups were high. The highest mean scores were reported by nurse practitioners on collaboration with practice nurses (4.4+/-0.6). The lowest mean scores were reported by practice nurses on collaboration with nurse practitioners (3.8+/-0.9). Conclusion: Due to large variations in Slovenian OOHC clinics with regard to how health care workers from different professional backgrounds perceive safety culture, more attention should be devoted to improving the team collaboration in OOHC. A clearer description of professional team roles should be provided. PMID- 29184418 TI - FGF2 promotes metastasis of uveal melanoma cells via store-operated calcium entry. AB - Uveal melanoma (UM), the most common primary intraocular malignancy in adults, is highly metastatic and associated with dismal prognosis. Fibroblast growth factor 2 (FGF2) has been shown to induce cell proliferation and angiogenesis of melanoma and other malignancies. However, the expression of FGF2 in UM and its effects on melanoma cell migration are not well known. In this study, we found FGF2 expression was related to UM histological subtype and presence of metastasis. In vitro experiments showed that FGF2 treatment caused increased horizontal and vertical migration and F-actin cytoskeleton assembly as well as decreased adhesive activity of MUM2B cells, together with increased intracellular calcium concentration and expression of ORAI1 and STIM1 - two key regulatory proteins of store-operated calcium entry (SOCE). The mouse xenograft model showed that MUM2B cells with FGF2 stimulation grew into larger tumor masses and were prone to metastasis. In addition, the SOCE inhibitor 2-aminoethoxydiphenyl borate (2-APB) reversed all of these effects of FGF2. Finally, human UM samples and mouse xenograft model samples were used to confirm the correlation of FGF2 with ORAI1 and STIM1 expression. Taken together, our study suggests that FGF2 promotes metastasis of UM via SOCE. PMID- 29184419 TI - Interleukin-6 upregulates SOX18 expression in osteosarcoma. AB - Aim: SOX18 is a potential oncogene in osteosarcoma via controlling osteosarcoma cell proliferation and metastasis. Interleukin-6 (IL-6), a major activator of Janus kinase 2 (JAK2)/signal transducers and activators of transcription 3 (STAT3) signaling, plays an important role in the growth of carcinoma cells. The present study aims to investigate the correlation between IL-6 and SOX18 in osteosarcoma. Materials and methods: Protein expression and mRNA expression were determined by Western blot and real-time polymerase chain reaction (PCR) analysis, respectively. Cell proliferation and apoptosis were identified by Cell Counting Kit-8 assay and flow cytometry analysis, respectively. Results: We found that SOX18, IL-6 and p-STAT3 were elevated in osteosarcoma compared with bone cyst tissues. A positive correlation between the mRNA levels of IL-6 and SOX18 was observed in osteosarcoma tissues. IL-6 stimulation dose dependently induced the mRNA and protein levels of SOX18 in U-2OS and MG63 cells. Furthermore, IL-6 significantly rescued the inhibitory and induction effects of SOX18 knockdown on osteosarcoma cell proliferation and apoptosis, respectively. The changes in cell proliferation (PCNA) and apoptosis-related proteins (Bcl-2, Bax and Cleaved Caspase 3) were in line with the results of cell proliferation and apoptosis assays. Conclusion: Our data suggest that IL-6 is a possible upstream regulator for SOX18 in osteosarcoma. PMID- 29184420 TI - Amatuximab and novel agents targeting mesothelin for solid tumors. AB - Mesothelin (MSLN) is considered a promising target for cancer therapy. Originally extracted in 1992 after the immunization of mice with a human ovarian cancer (OC) cell line and cloned in 1996, MSLN seems to be involved in cell adhesion and metastasis. MSLN is prevalent in mesothelia tissues but is expressed in several human cancers, such as OC, pancreatic cancer, mesothelioma, and lung cancer. Amatuximab (MORAb-009) is a mouse-human chimeric monoclonal antibody with a selective affinity for MSLN. The principal mechanism of action comprises inhibition of binding of MSLN with the antigen CA125/MUC16. The highest phase of development is actually a Phase II trial (MORAb-009-201, Europe). In this review, we describe the mechanism of action of amatuximab and other MSLN-targeting novel drugs, along with a discussion about the expected efficacy, safety, and toxicity of this promising group of agents and implications for future research and clinical practice. PMID- 29184421 TI - LncRNA expression and implication in osteosarcoma: a systematic review and meta analysis. AB - Purpose: Osteosarcoma is the most prevalent primary bone tumor in children, adolescents, and older adults, typically presenting with poor survival outcomes. In recent years, ample evidence has shown that many long noncoding RNAs (lncRNAs) have been aberrantly expressed in osteosarcoma, demonstrating their potential to serve as prognostic markers. In this study, we performed a meta-analysis on four lncRNAs (TUG1, UCA1, BCAR4, and HULC) to systematically evaluate their prognostic value in osteosarcoma. Materials and methods: The eligible articles were systematically searched in PubMed, Web of Science, Embase, and Elsevier ScienceDirect (up to September 22, 2017), and one meta-analysis concerning the association between lncRNA expression and the overall survival (OS) of osteosarcoma patients was performed. Survival outcomes were analyzed by OS. Subgroup analyses were performed. Results: A total of 1,361 patients with osteosarcoma and 12 lncRNAs from 16 articles were included in the study. Of the listed lncRNAs, the high expression of 10 lncRNAs indicated worse survival outcomes, while only two lncRNAs were shown to positively affect patients' OS. Conclusion: This meta-analysis indicated that the abnormally expressed lncRNAs might significantly affect the survival of osteosarcoma patients. Combined use of these lncRNAs may serve as potential novel biomarkers for the indication of clinical outcomes of osteosarcoma patients as well as the selection of adjuvant chemotherapy strategies for clinical treatment of this disease. PMID- 29184424 TI - Erratum: Drug treatment of type 2 diabetes mellitus in patients for whom metformin is contraindicated [Corrigendum]. AB - [This corrects the article on p. 15 in vol. 7, PMID: 24465132.]. PMID- 29184422 TI - Prevalence of hepatitis C virus-resistant association substitutions to direct acting antiviral agents in treatment-naive hepatitis C genotype 1b-infected patients in western China. AB - Background: Direct-acting antivirals (DAAs) against hepatitis C virus (HCV) are potent and highly efficacious. However, resistance-associated substitutions (RASs) relevant to DAAs can impair treatment effectiveness even at baseline. Moreover, the prevalence of baseline RASs in HCV genotype 1b-infected patients in western China is still unclear. Materials and methods: Direct sequencing of the HCV NS3, NS5A, and NS5B regions was performed in baseline serum samples of 70 DAAs treatment-naive HCV 1b-infected patients in western China. The sequences were analyzed with MEGA version 5.05 software. Evolutionary patterns of RASs and amino-acid covariance patterns in the NS3, NS5A, and NS5B genes were analyzed by MEGA and Cytoscape (version 3.2.1), respectively. Results: The presence of at least one RAS in the NS3 region (C16S, T54S, Q80R/L, A87T, R117H, S122G, V132I, V170I) was observed in 85.48% (53 of 62) of patients, RASs in the NS5A region (L28M, R30Q, Q54H, P58S/T, Q62H/R, Y93H) were observed in 42.42% (28 of 66) of patients, and RASs in the NS5B region (N142S, A300T, C316N, A338V, S365A, L392I, M414L, I424V, A442T, V499A, S556G) were observed in 100% (44 of 44) of patients. Evolutionary patterns of RASs and amino-acid covariance patterns for the NS3, NS5A, and NS5B genes are reported. Conclusion: The prevalence of RASs relevant to DAAs detected in the NS3, NS5A, and NS5B regions of HCV 1b from DAA treatment naive patients is high. Therefore, more attention should be paid to RASs associated with DAAs in the upcoming DAA-treatment era in China. PMID- 29184423 TI - Propofol or benzodiazepines for short- and long-term sedation in intensive care units? An economic evaluation based on meta-analytic results. AB - Purpose: This evaluation compares propofol and benzodiazepine sedation for mechanically ventilated patients in intensive care units (ICUs) in order to identify the potential economic benefits from different payers' perspectives. Methods: The patient-level simulation model incorporated efficacy estimates from a structured meta-analysis and ICU-related costs from Italy, Germany, France, UK, and the USA. Efficacy outcomes were ICU length of stay (LOS), mechanical ventilation duration, and weaning time. We calculated ICU costs from mechanical ventilation duration and ICU LOS based on national average ICU costs with and without mechanical ventilation. Three scenarios were investigated: 1) long-term sedation >24 hours based on results from randomized controlled trials (RCTs); 2) long-term sedation based on RCT plus non-RCT results; and 3) short-term sedation <24 hours based on RCT results. We tested the model's robustness for input uncertainties by deterministic (DSA) and probabilistic sensitivity analyses (PSA). Results: In the base case, mean savings with propofol versus benzodiazepines in long-term sedation ranged from ?406 (95% confidence interval [CI]: 646 to 164) in Italy to 1,632 ? (95% CI: 2,362 to 880) in the USA. Inclusion of non-RCT data corroborated these results. Savings in short-term sedation ranged from ?148 (95% CI: 291 to 2) in Italy to ?502 (95% CI: 936 to 57) in the USA. Parameters related to ICU and mechanical ventilation had a stronger influence in the DSA than drug-related parameters. In PSA, propofol reduced costs and ICU LOS compared to benzodiazepines in 94%-100% of simulations. The largest savings may be possible in the UK and the USA due to higher ICU costs. Conclusion: Current ICU sedation guidelines recommend propofol rather than midazolam for mechanically ventilated patients. This evaluation endorses the recommendation as it may lead to better outcomes and savings for health care systems, especially in countries with higher ICU-related costs. PMID- 29184425 TI - Obesity and morbid obesity associated with higher odds of hypoalbuminemia in adults without liver disease or renal failure. AB - Background and objective: Studies are needed in order to inform recommendations for interpreting albumin levels among obese individuals without known medical conditions associated with hypoalbuminemia. The objective of this study was to examine the association of obese and morbidly obese status with hypoalbuminemia, while adjusting for age, sex, diabetes, prediabetes, diabetic nephropathy, and nephrotic syndrome. Patients and methods: Retrospective data collection from adult patients presenting to the outpatient Endocrinology and Metabolism Clinic was performed between January 2015 and December 2015. An initial sample of 180 patients was selected. After excluding patients who were younger than 18 years, who had known cases of liver disease or renal failure, or who had missing data, a final sample of 122 subjects was identified. Serum albumin and objectively measured weight and height data were retrieved from hospital records. A board certified endocrinologist reviewed patient records to identify the presence of renal and diabetic conditions. Descriptive statistics were used to examine sample characteristics. Multiple logistic regression analysis was used to examine the association of obesity and morbid obesity with hypoalbuminemia (serum albumin < 34 g/L) while adjusting for age, sex, diabetes, prediabetes, diabetic nephropathy, and nephrotic syndrome. Results: Approximately 43% of the sample were categorized as obese and 13% were categorized as morbidly obese. The mean serum albumin level was 38.00 g/L (standard deviation [SD] = 4.26) among subjects who were neither overweight nor obese, 38.35 g/L (SD = 0.48) among overweight subjects, 34.57 g/L (SD = 4.71) among obese subjects, and 33.81 g/L (SD = 3.71) among morbidly obese subjects. Adjusting for age, sex, diabetes, prediabetes, nephrotic syndrome, and diabetic nephropathy, obese subjects had significantly higher odds of hypoalbuminemia (odds ratio [OR]: 4.10, 95% confidence interval [CI]: 1.50-11.27, P-value = 0.006), as did morbidly obese subjects (OR: 6.94, 95% CI: 1.91-25.23, P-value = 0.003). Conclusion: The findings suggest that obesity and morbid obesity can be considered as independent predictors of hypoalbuminemia. The findings can be used to inform future studies aiming to better understand the association of obesity and morbid obesity with hypoalbuminemia and to help inform guidelines for clinicians on how to correctly interpret and utilize serum albumin data for obese individuals. PMID- 29184426 TI - Recommendations for volume augmentation and rejuvenation of the face and hands with the new generation polycaprolactone-based collagen stimulator (Ellanse(r)). AB - Background: The range of fillers currently available for soft-tissue augmentation is constantly expanding. The latest advances in filler technology include collagen biostimulators that exert their esthetic effect by promoting neocollagenesis. One such product is the next-generation collagen biostimulator (Ellanse(r)) that demonstrates properties as yet unseen in soft-tissue fillers. It is composed of polycaprolactone (PCL) microspheres in an aqueous carboxymethylcellulose gel carrier. Given its specific characteristics and the number of areas that can be treated with this innovative product, experts' recommendations were deemed necessary and are therefore presented in this paper with a specific focus on the indications, treatment areas and procedures as well as injection techniques. Methods: A multinational, multidisciplinary group of plastic surgeons and dermatologists convened to develop recommendations with a worldwide perspective. This publication provides information on the specific characteristics of the product and focuses on the recommendations on the injection techniques. Results: Recommendations on injection techniques are provided for the upper face, mid-face and lower face and zone by zone for each of these areas, as well as hands. Based on the particular anatomy of each area, the focus is on the techniques and devices of injection and the volume and depth of injection. The information is tabulated, and photos are presented for illustration. Conclusion: These recommendations provide a guideline for physicians who wish to perform safe and efficacious treatment with the PCL collagen stimulator for face and rejuvenation with volume augmentation. PMID- 29184427 TI - Pemphigoid gestationis: current perspectives. AB - Many skin diseases can occur in pregnant women. However, a few pruritic dermatological conditions are unique to pregnancy, including pemphigoid gestationis (PG). As PG is associated with severe morbidity for pregnant women and carries fetal risks, it is important for the clinician to quickly recognize this disease and refer it for dermatological evaluation and treatment. Herein, we review the pathogenesis, clinical characteristics, and management of PG. PMID- 29184429 TI - Topical application of ST266 reduces UV-induced skin damage. AB - Ultraviolet radiation (UVR) has a significant impact on human skin and is the major environmental factor for skin cancer formation. It is also believed that 80% of the signs of skin aging are attributed to UVR. UVR induces inflammatory changes in the skin via the increase in oxidative stress, DNA damage vascular permeability, and fluctuation in a myriad of cytokines. Acutely, UVR causes skin inflammation and DNA damage, which manifest as sunburn (erythema). ST266 is the secretome of proprietary amnion-derived cells that have been shown to reduce inflammation and accelerate healing of various wounds by promoting migration of keratinocytes and fibroblasts in preclinical animal studies. We hypothesized that ST266 has anti-inflammatory effects that can be used to reduce ultraviolet (UV) erythema and markers of inflammation. In this study, we examined the in vivo effects of ST266 on post UV-irradiated skin by measuring erythema, level of cyclobutane pyrimidine dimer (CPD), and expression level of xeroderma pigmentosum, complementation group A (XPA). We demonstrated that ST266 has the potential to reduce the acute effects of UV-induced skin damage when applied immediately after the initial exposure. In addition, ST266 is shown to reduce erythema, increase XPA DNA repair protein, and decrease damaged DNA. PMID- 29184428 TI - Management of refractory pityriasis rubra pilaris: challenges and solutions. AB - Pityriasis rubra pilaris (PRP) is a rare chronic inflammatory papulosquamous skin disease. Its clinical presentation and evolution is very variable. The most frequent clinical features are follicular papules, progressing to yellow-orange erythroderma with round small areas of normal skin and the well-demarcated palmoplantar keratoderma. Actually, six different types of PRP have been described based on clinical characteristics, age of onset, and prognosis. The pathogenesis is still unknown, and treatment can be challenging. Available treatments are mainly based on case reports or case series of clinical experience because no controlled randomized trials have never been performed because of the rarity of the condition. Traditional systemic treatment consists in retinoids, which are actually considered as first-line therapy, but refractory cases that do not respond or relapse after drug interruption do exist. In recent years, numerous reports have demonstrated the efficacy of new agents such as biological drugs. This article is an overview on available therapeutic options, in particular for refractory forms of PRP. PMID- 29184430 TI - Evaluation of a fecal immunochemistry test prior to colonoscopy for outpatients with various indications. AB - Background: Stool tests can predict advanced neoplasms prior to colonoscopy. Results of immunochemical stool tests to predict findings at colonoscopy for various indications are less often reported. We compared pre-colonoscopy stool tests with findings in patients undergoing colonoscopy for different indications. Patients and methods: Charts of patients undergoing elective or semi-urgent colonoscopy were reviewed. Comparison of adenoma detection rates and pathological findings was made between prescreened and non-prescreened, and between stool positive and stool-negative cases. Demographics, quality of colonoscopy, and pathological findings were recorded. Odds ratios (ORs) and 95% confidence intervals (CIs) were assessed. Statistical significance was accepted at p<=0.05. Results: Charts of 325 patients were reviewed. Among them, stool tests were done on 144 patients: 114 were negative and 30 were positive. Findings were similar in the pretest and non-pretest groups. Detection of advanced adenomas per patient was higher in the stool-positive group compared to the stool-negative group (23.4% vs 3.5%, p=0.0016, OR =7.6 [95% CI: 2-29.3]). Five advanced adenomas (without high-grade dysplasia or adenocarcinoma) and several cases of multiple adenomas were missed in the negative group. Sensitivity and specificity for advanced polyps was 63.6% and 82.7%, respectively. The negative predictive value was 96.5%. Male gender was independently predictive of any adenoma. Conclusion: The stool immunochemical test best predicted advanced neoplasms and had a high negative predictive value in this small cohort. Whether this test can be applied to determine the need for colonoscopy in groups other than average risk would require more studies. PMID- 29184431 TI - Update on the clinical utility of an RNA interference-based treatment: focus on Patisiran. AB - RNA interference (RNAi) is a naturally existing endogenous mechanism for post transcriptional gene regulation, nowadays commonly utilized for functional characterization of genes and development of potential treatment strategies for diseases. RNAi-based studies for therapy, after being examined for over a decade, are finally in the pipeline for developing a potential treatment for the mutated transthyretin (TTR) gene, which gives rise to a dysfunctional TTR protein. This dysfunctional protein causes TTR amyloidosis (ATTR), an inherited, progressively incapacitating, and often fatal genetic disorder. TTR is a protein produced in the liver, and functions as a carrier for retinol-binding protein and also thyroxine. This protein facilitates the transport of vitamin A around the human body. A mutation or misprint in the code of this protein results in an abnormal folding of the protein. Therefore, not only does the transportation of the vitamin A become disabled, but also there will be formation of clusters called amyloid deposits, which attack the heart and the nerves causing some patients to be unconditionally bound to bed. ATTR is a hereditary autosomal dominant disease with a 50% chance of inheritance by offspring, even with just one of the parents having a single defective allele of this gene. Alnylam Pharmaceuticals worked on the concept of RNAi therapy for years, which led to the introduction of lipid nanoparticles encircling small interfering RNAs. The drug showed extremely positive results since the first trial, and a great percentage of defective protein reduction. This drug was later named Patisiran. PMID- 29184432 TI - Role of magnetic resonance planimetry and magnetic resonance parkinsonism index in discriminating Parkinson's disease and progressive supranuclear palsy: a retrospective study based on 1.5 and 3 T MRI. AB - Objective: The objective of the study was to assess magnetic resonance (MR) planimetric measurements and MR parkinsonism index (MRPI) in differentiating progressive supranuclear palsy (PSP) from Parkinson's disease (PD) using 1.5 and 3 T MRI scanner. Subjects and methods: After ethical approval was obtained, analysis of 34 consecutive patients with PSP, 34 patients with PD and 34 healthy controls (HCs) was performed. HCs were age-matched adults without any history of neurodegenerative disease or movement disorders. Retrospective data from the past 10 years (from January 2006 to December 2015) were obtained from the Hospital Information Management System, and informed consent was obtained from all participants. The measurements of pons area-midbrain area ratio (P/M) and MCP width-superior cerebellar peduncle (SCP) width ratio (MCP/SCP) were used, and MRPI was calculated by the formula ([P/M]*[MCP/SCP]). Results: Midbrain area and SCP width in patients with PSP (19 males, 15 females; mean age =66.7 years) were significantly (P<0.001) smaller than in patients with PD (20 males, 14 females; mean age =66.7 years) and control participants (17 males, 17 females; mean age =66.1 years). P/M and MCP/SCP were significantly higher in patients with PSP than in patients with PD and control participants. All measurements showed some overlap of values between patients with PSP and patients from PD group and control participants. MRPI value was significantly higher in patients with PSP (mean 21.00) than in patients with PD (mean 9.50; P<0.001) and control participants (mean 9.6; P<0.001), without any overlap of values among groups. No correlation was found between the duration of disease, PSP rating scale, PSP staging system and MRPI in this study. No patient with PSP received a misdiagnosis when the index was used (sensitivity and specificity, 100%). Conclusion: MRPI should be made an essential part of all MRI brain reporting whenever differentiation between PD and PSP is sought for. PMID- 29184433 TI - Diagnosis and treatment of irritable bowel syndrome with predominant constipation in the primary-care setting: focus on linaclotide. AB - Irritable bowel syndrome (IBS) is a complex functional gastrointestinal disorder that is exceedingly common in clinical practice. IBS with predominant constipation (IBS-C) is a subtype of IBS that accounts for more than a third of the IBS diagnosed. Diagnosis of IBS requires a careful personalized approach, a comprehensive clinical history, limited but relevant investigations, and continued follow-up. Major IBS societies and guidelines recommend offering a positive diagnosis of IBS based on presenting symptomatology. Abdominal pain that may or may not be relieved by defecation is the cardinal symptom of IBS; distension and bloating are other common symptoms. Careful attention should be paid to alarm symptoms before a diagnosis of IBS is made. Pharmacotherapy with linaclotide is recommended for moderate-severe IBS-C, based on high-quality evidence from randomized controlled trials. Diarrhea is the major side effect of linaclotide, and limited cost-effectiveness data currently exist. PMID- 29184434 TI - Manifestation of non-ST elevation myocardial infarction due to hyperthyroidism in an anomalous right coronary artery. AB - Introduction: Anomalous origin of the right coronary artery (RCA) from the left coronary cusp of the aorta is a moderately rare but potentially life-threatening incident. Myocardial infarction (MI) and sudden cardiac death have been described with this anomaly, especially in those who engage in excessive exercise. However, this case study shows this incidence in association with hyperthyroidism. Case description: A previously healthy 51-year-old female with history of hypothyroidism presented with acute onset chest pain for 1 day. Patient's electrocardiogram was normal, however, she had elevated troponins and given her typical chest pain, she was diagnosed with acute coronary syndrome (ACS). The patient had been on levothyroxine and was found to have a subnormal thyroid stimulating hormone level suggesting hyperthyroidism. Echocardiogram was normal. Coronary angiogram showed an anomalous RCA arising from the left coronary cusp of the sinus of Valsalva and no evidence of atherosclerosis. A coronary computed tomography angiogram was done confirming this finding and showed a slit-like deformity of the coronary ostium with at least 50% luminal stenosis. The patient was referred to a cardiothoracic surgeon for potential coronary artery bypass graft. Discussion: This case illustrates a rare presentation of ACS due to hyperthyroidism in an anomalous RCA. MI is a rare manifestation of hyperthyroidism, but in combination with an anatomical defect, it can potentiate adverse outcomes. The mechanisms by which thyroid hormones influence cardiovascular hemodynamics are by causing a hyperdynamic circulatory state, increasing myocardial oxygen demand, and increasing the risk of coronary vasospasm. The combination of anatomic and metabolic defects is what likely precipitated this patient's outcome. PMID- 29184435 TI - Prevalence and association of vitamin D deficiency and mortality in patients with severe sepsis. AB - Background: Vitamin D is a steroid prohormone that regulates body calcium and phosphate metabolism. Recent studies have shown an association between low vitamin D status and high mortality in patients admitted to intensive care units. To date, there are limited data available specifically about severely septic patients in medical units. Objectives: To determine the prevalence of vitamin D deficiency in severely septic patients and its clinical outcomes, including mortality rate. Methods: A prospective observational study was conducted to investigate the prevalence of vitamin D deficiency and its association with 30 day mortality in patients with severe sepsis. Patients admitted to medical wards at our hospital between November 2014 and March 2015 were included in the study. A 25-hydroxyvitamin D level <20 ng/mL was defined as vitamin D deficiency, and <12 ng/mL as severe deficiency. For an association analysis, the patients were grouped into deficient versus not deficient and severely deficient versus not severely deficient. Results: One hundred and ten eligible patients were enrolled. A total of 83 patients (75%) had vitamin D deficiency and 42 (38%) had severe deficiency. Despite an insignificant higher 30-day hospital mortality rate in vitamin D deficient versus non-deficient groups (16% vs 4%, p=0.18), the differences were significant between the severely deficient versus non-severe groups (23% vs 4%, p=0.02). The odds ratio of the 30-day mortality rate was 4.83 (95% confidence interval [CI], 0.60-38.77, p=0.14) for vitamin D deficiency and 7.69 (95% CI, 2.00-29.55, p=0.003) for severe deficiency. Conclusion: The prevalence of vitamin D deficiency was very high in three-quarters of patients with severe sepsis. A significant higher mortality rate was observed, particularly in patients with severe vitamin D deficiency. PMID- 29184436 TI - Continuous wound infusion with chloroprocaine in a pig model of surgical lesion: drug absorption and effects on inflammatory response. AB - Continuous wound infusion (CWI) may protect from inflammation, hyperalgesia and persistent pain. Current local anesthetics display suboptimal pharmacokinetic profile during CWI; chloroprocaine (CP) has ideal characteristics, but has never been tested for CWI. We performed an animal study to investigate the pharmacokinetic profile and anti-inflammatory effect of CP during CWI. A total of 14 piglets received an infusion catheter after pararectal laparotomy and were randomly allocated to one of three groups: 5 mL/h infusion of saline (group A), CP 1.5% (group B) and CP 0.5% (group C). Blood sampling was performed to assess absorption and systemic inflammation at 0, 3, 6, 12, 24, 48, 72, 96, 102 and 108 hours. The wound and contralateral healthy abdominal wall were sampled for histological analyses. Absorption of CP from the site of infusion, evaluated as the plasmatic concentrations of CP and its metabolite, 4-amino-2-chlorobenzoic acid (CABA), showed a peak during the first 6 hours, but both CP and its metabolite rapidly disappeared after stopping CP infusion. Local inflammation was reduced in groups B and C (CP-treated p < 0.001), in a CP dose-dependent fashion. While CP inhibited in a dose-dependent manner pig mononuclear cells (MNCs) in vitro proliferation to a polyclonal activator, no effect on systemic cytokines' concentrations or on ex vivo monocytes' responsiveness was observed, suggesting the lack of systemic effects, in line with the very short half-life of CP in plasma. CP showed a very good profile for use in CWI, with dose-dependent local anti-inflammatory effects, limited absorption and rapid clearance from the bloodstream upon discontinuation. No cytotoxicity or side effects were observed. CP, therefore, may represent an optimal choice for clinical CWI, adaptable to each patient's need, and protective on wound inflammatory response (and hyperalgesia) after surgery. PMID- 29184437 TI - Antiallodynic and antihyperalgesic activities of zerumbone via the suppression of IL-1beta, IL-6, and TNF-alpha in a mouse model of neuropathic pain. AB - Background: Neuropathic pain is a debilitating condition that severely affects the quality of life for those with this pain condition, and treatment for pain relief is greatly sought-after. Zerumbone (Zer), a sesquiterpene compound isolated from the rhizomes of a Southeast Asian ginger plant, Zingiber zerumbet (L.) Roscoe ex Smith. (Zingiberaceae), showed antinociceptive and antiinflammatory properties when previously tested on models of nociception and inflammation. Objective: This study investigated the effects of prophylactic administration of zerumbone on allodynia and hyperalgesia in a mouse model of chronic constriction injury (CCI)-induced neuropathic pain. Methods: Intraperitoneal administration of Zer (5-50 mg/kg) from day 1 post-surgery was carried out to identify the onset and progression of the pain condition. Responses toward mechanical and cold allodynia, and mechanical and thermal hyperalgesia were assessed on days 3, 5, 7, 9, 11, and 14 post-surgery. Blood plasma and spinal cord levels of interleukin (IL)-1beta, IL-6, tumor necrosis factor-alpha, and IL-10 were screened using enzyme-linked immunosorbent assay on day 15. Results: Zer (10 and 50 mg/kg) attenuated pain symptoms on all days of behavioral testing without any signs of sedation in the rotarod test. ED50 values for mechanical allodynia, cold allodynia, thermal hyperalgesia, and mechanical hyperalgesia were 9.25, 9.507, 8.289, and 9.801 mg/kg, respectively. Blood plasma and spinal levels of IL-1beta, IL-6, and tumor necrosis factor-alpha but not IL 10 were significantly (p<0.05) suppressed by zer treatment. Discussion and conclusion: Zer exhibits its antiallodynic and antihyperalgesic properties via reduced sensitization at nociceptor neurons possibly through the suppression of inflammatory mediators. Zer may prove to be a novel and beneficial alternative for the management of neuropathic pain. PMID- 29184438 TI - Efficacy of local dexmedetomidine add-on for spermatic cord block anesthesia in patients undergoing intrascrotal surgeries: randomized controlled multicenter clinical trial. AB - Study objective: The objective of this study was to evaluate the effect of adding dexmedetomidine (DEX) to bupivacaine on the quality of spermatic cord block anesthesia and postoperative analgesia. Design: This is a randomized, double blind study. Setting: This study was performed in an educational and research hospital. Patients: One hundred twenty adult males were scheduled for intrascrotal surgeries. Interventions: Patients were divided into two groups: group B received 10 mL of bupivacaine 0.25% for spermatic cord block and intravenous 50 ug of DEX and group BD received 10 mL of bupivacaine 0.25% added to 50 ug of DEX (9.5 mL bupivacaine 0. 25% + 0.5 mL [50 ug] DEX) for spermatic cord block, and for masking purposes, the patients received isotonic saline intravenously. Measurements: Time to first analgesic request, analgesic consumption, and visual analog scale (VAS) pain score in the first 24 hours postoperatively were assessed. Main results: Time to first rescue analgesic was significantly delayed in group BD in comparison with group B, median (interquartile) range, 7 (6-12) hours versus 6 (5-7) hours, (p=0.000), the mean cumulative morphine consumption (mg) in the first postoperative 24 hours was significantly lower in group BD compared with group B, 8.13+/-4.45 versus 12.7+/ 3.79, with a mean difference (95% CI) of -4.57 (-6.06 to -3.07) (p=0.000); also, there was a significant reduction of VAS pain score in group BD in comparison with group B at all measured time points, VAS 2 hours (1.28+/-0.9 vs 1.92+/-0.8), VAS 6 hours (2.62+/-1.5 vs 3.93+/-1.2), VAS 12 hours (2.40+/-1.1 vs 3.57+/-0.65), VAS 24 hours (1.90+/-0.68 vs 2.53+/-0.62) (p=0.000). Conclusion: The addition of 50 ug of DEX to bupivacaine 0.25% in spermatic cord block for intrascrotal surgeries resulted in delay of first analgesic supplementation, reduction of postoperative analgesic consumption as well as improvement of the success rate of the block. PMID- 29184439 TI - Ultrasound-guided rectus sheath block, caudal analgesia, or surgical site infiltration for pediatric umbilical herniorrhaphy: a prospective, double blinded, randomized comparison of three regional anesthetic techniques. AB - Background: Umbilical hernia repair is a common pediatric surgical procedure. While opioid analgesics are a feasible option and have long been a mainstay in the pharmacological intervention for pain, the effort to improve care and limit opioid-related adverse effects has led to the use of alternative techniques, including regional anesthesia. The current study prospectively compares the analgesic efficacy of three techniques, including caudal epidural blockade, peripheral nerve blockade, and local wound infiltration, in a double-blinded study. Patients and methods: A total of 39 patients undergoing umbilical hernia repair were randomized to receive a caudal epidural block (CDL), ultrasound guided bilateral rectus sheath blocks (RSB), or surgical site infiltration (SSI) with local anesthetic. Intraoperative anesthetic care was standardized, and treatment groups were otherwise blinded from the intraoperative anesthesiology team and recovery nurses. Postoperatively, the efficacy was evaluated using Hannallah pain scores, Aldrete recovery scores, the need for intravenous fentanyl, and the time to discharge. Results: Each cohort was similar in terms of age, weight, premedication dosing, length of case, intraoperative and postoperative fentanyl requirements, and time to tracheal extubation. Among the three cohorts, there were no significant differences noted in terms of pain scores or time to recovery. Conclusion: All the three techniques provided effective analgesia following umbilical hernia repair. Our findings offer effective and safe analgesic options as alternatives to the neuraxial (caudal) approach. PMID- 29184440 TI - Administration of epidural labor analgesia is not associated with a decreased risk of postpartum depression in an urban Canadian population of mothers: a secondary analysis of prospective cohort data. AB - Background: Postpartum depression (PPD) is a common complication of pregnancy, affecting approximately 13% of mothers internationally. Previous research has examined whether epidural analgesia used for pain control during labor and birth is associated with a lower risk of PPD, but reports conflicting results and may have suffered from methodological shortcomings. Our study aimed to prospectively assess whether epidural analgesia is associated with a lower risk of PPD (at either 6 weeks or 6 months postpartum) after attempting to adequately adjust for selection bias and confounding variables. Methods: We conducted a secondary analysis of a prospective cohort of urban Canadian mothers who were recruited at birth in Calgary, Canada, in 2010, for a primary study on predictors of PPD. Mothers with full-term, singleton infants who did not require neonatal intensive care unit admission of >24 hours were included, and filled out questionnaires at birth, 6 weeks and 6 months postpartum including demographics, birth data, maternal and infant physical health, lifestyle, breastfeeding and maternal mental health. Descriptive statistics were calculated for participant characteristics and to identify potential confounder variables. Multivariable logistic regression analysis was conducted to assess whether epidural analgesia is associated with PPD after controlling for available confounding variables. Results: Our study included 206 mothers who had vaginal deliveries and were free of depression at delivery. We found an incidence of PPD of 13.3% (n=27) and no statistically significant association between epidural use and PPD, regardless of adjustment for potential confounding variables (unadjusted odds ratio [OR] 0.86, 95% confidence interval [CI] 0.69-1.22; adjusted OR (for body mass index 1.04, 95% CI 0.40-2.77). Conclusion: We did not observe a significant association between epidural use and PPD. While the CIs are wide, we do not believe that this masks a clinically relevant association, and as such, the risks and benefits of epidural analgesia communicated to women during labor and delivery should not be modified. PMID- 29184441 TI - Potential role of radiation therapy in augmenting the activity of immunotherapy for gynecologic cancers. AB - Immune checkpoint inhibitors have become an area of intense interest in oncology and are actively being studied in a variety of cancer types with a wide range of success. In vitro data suggest mechanisms by which radiation can activate the immune system, and ongoing studies are exploring the potential interaction of checkpoint inhibitors with radiotherapy in both preclinical and clinical settings. Gynecologic malignancies are a heterogeneous group of tumors with varying prognoses, intrinsic immunogenicity, and potential for response to immune based therapies. In this review, we focus on the rationale for immunotherapy and opportunities for augmentation by photon radiotherapy in cancers of the cervix, endometrium, and ovary. PMID- 29184442 TI - Exome and transcriptome sequencing identifies loss of PDLIM2 in metastatic colorectal cancers. AB - Background: Understanding the genomic determinants associated with metastasis in colorectal cancers (CRCs) provides crucial clues for improving patient care. Patients and methods: In this study, we performed whole-exome sequencing as well as RNA sequencing analyses on five pairs of primary and liver metastasized samples from CRC patients together with blood/normal control samples for each pair. Results: We identified genomic deletions in the region of 8p21-23 (q value <0.01) from analysis of recurrent regions with copy number variations in both primary and matched metastatic lesions. Consistent with this result, we found significantly decreased expression levels of all 12 genes (ADAMDEC1, C8orf80, CLDN23, EPHX2, GFRA2, NEFL, NEFM, PDLIM2, PTK2B, SCARA5, SLC18A1 and STMN4) located within this region (adjusted P<0.01). Notably, the mRNA levels of PDLIM2, a key regulator of well-known cancer-associated genes including the proto oncogene c-MYC, an early response gene IER3, and regulators of apoptosis such as BCL2, FAS, and FASLG, were highly downregulated in tumors compared to normal tissues. Conclusion: Taken together, our findings uncovered various genomic alterations potentially leading to metastasis in CRC and provide important insights into the development of potential therapeutic targets for preventing metastatic progression of CRC. PMID- 29184443 TI - Training surgeons in shared decision-making with cancer patients aged 65 years and older: a pilot study. AB - Objective: Treatment decision-making in older patients with colorectal (CRC) or pancreatic cancer (PC) needs improvement. We introduced the EASYcare in Geriatric Onco-surgery (EASY-GO) intervention to optimize the shared decision-making (SDM) process among these patients. Methods: The EASY-GO intervention comprised a working method with geriatric assessment and SDM training for surgeons. A non equivalent control group design was used. Newly diagnosed CRC/PC patients aged >=65 years were included. Primary patient-reported experiences were the quality of SDM (SDM-Q-9, range 0-100), involvement in decision-making (Visual Analog Scale for Involvement in the decision-making process [range 0-10]), satisfaction about decision-making (Visual Analog Scale for Satisfaction concerning the decision-making process [range 0-10]), and decisional regret (Decisional Regret Scale [DRS], range 0-100). Only for DRS, lower scores are better. Results: A total of 71.4% of the involved consultants and 42.9% of the involved residents participated in the EASY-GO training. Only 4 trained surgeons consulted patients both before (n=19) and after (n=19) training and were consequently included in the analyses. All patient-reported experience measures showed a consistent but non-significant change in the direction of improved decision-making after training. According to surgeons, decisions were significantly more often made together with the patient after training (before, 38.9% vs after, 73.7%, p=0.04). Sub-analyses per diagnosis showed that patient experiences among older PC patients consistent and clinically relevant changed in the direction of improved decision-making after training (SDM-Q-9 +13.4 [95% CI -7.9; 34.6], VAS-I +0.27 [95% CI -1.1; 1.6], VAS-S +0.88 [95% CI -0.5; 2.2], DRS -10.3 [95% CI -27.8; 7.1]). Conclusion: This pilot study strengthens the practical potential of the intervention's concept among older surgical cancer patients. PMID- 29184445 TI - The relation of CUN-BAE index and BMI with body fat, cardiovascular events and diabetes during a 6-year follow-up: the Hordaland Health Study. AB - Objective: We compared Clinica Universidad de Navarra-Body Adiposity Estimator (CUN-BAE) and body mass index (BMI) as correlates of body fat percent (BF%) and the association with future risk of cardiovascular disease (CVD) and type 2 diabetes in a Caucasian population. Methods: We used data from 6796 individuals (born 1925-27 and 1950-52) from the Hordaland Health Study, a prospective cohort study in Norway. The study was conducted in 1992-1993 and 1997-1999. Cross sectional analyses were conducted with data from 1997/99, including BF% measured by dual-energy X-ray absorptiometry. Longitudinal analyses included BMI and CUN BAE calculated in 1992/93, and self-reported information on CVD events and diabetes in 1997/99. Results: The correlation between CUN-BAE and BF% (r=0.88) was stronger than between BMI and BF% (r=0.56). In sex-stratified analyses, CUN BAE and BMI correlated similarly with BF% in men (r=0.77 and r=0.76, respectively) and women (r=0.82 and r=0.81, respectively). In longitudinal analyses, the odds ratio (per 1 SD increase) of CVD and type 2 diabetes was higher for BMI (ORCVD =1.23 [95% CI: 1.11-1.36]; ORdiabetes =2.11 [1.82-2.45]) than for CUN-BAE (ORCVD =1.15 [1.04-1.27]; ORdiabetes =2.06 [1.72-2.47]) in the total population. In sex-stratified analyses, CUN-BAE showed higher CVD and diabetes risk than BMI: in men BMI ORCVD =1.22 (1.04-1.44), ORdiabetes =2.13 (1.64-2.83); CUN-BAE ORCVD =1.93 (1.54-2.43), ORdiabetes =4.33 (2.80-6.71); and in women BMI ORCVD =1.22 (1.07-1.39), ORdiabetes =2.11 (1.76-2.53); CUN-BAE ORCVD =2.06 (1.69-2.51), ORdiabetes =5.45 (3.87-7.67). Conclusion: CUN-BAE is more strongly associated with future risk of type 2 diabetes and CVD compared with BMI in analysis stratified by sex. As a measure of adiposity in men and women separately, CUN-BAE has no advantage over BMI, except when the value of estimated BF% itself is of interest. PMID- 29184444 TI - Development and validation of a panel of five proteins as blood biomarkers for early detection of colorectal cancer. AB - Objective: Reliable noninvasive biomarkers for early detection of colorectal cancer (CRC) are highly desirable for efficient population-based screening with high adherence rates. We aimed to discover and validate blood-based protein markers for the early detection of CRC. Patients and methods: A two-stage design with a discovery and a validation set was used. In the discovery phase, plasma levels of 92 protein markers and serum levels of TP53 autoantibody were measured in 226 clinically recruited CRC patients and 118 controls who were free of colorectal neoplasms at screening colonoscopy. An algorithm predicting the presence of CRC was derived by Lasso regression and validated in a validation set consisting of all available 41 patients with CRC and a representative sample of 106 participants with advanced adenomas and 107 controls free of neoplasm from a large screening colonoscopy cohort (N=6018). Receiver operating characteristic (ROC) analyses were conducted to evaluate the diagnostic performance of individual biomarkers and biomarker combinations. Results: An algorithm based on growth differentiation factor 15 (GDF-15), amphiregulin (AREG), Fas antigen ligand (FasL), Fms-related tyrosine kinase 3 ligand (Flt3L) and TP53 autoantibody was constructed. In the validation set, the areas under the curves of this five marker algorithm were 0.82 (95% CI, 0.74-0.90) for detecting CRC and 0.60 (95% CI, 0.52-0.69) for detecting advanced adenomas. At cutoffs yielding 90% specificity, the sensitivities (95% CI) for detecting CRC and advanced adenomas were 56.4% (38.4%-71.8%) and 22.0% (13.4%-35.4%), respectively. The five-marker panel showed similar diagnostic efficacy for the detection of early- and late stage CRC. Conclusion: The identified most promising biomarkers could contribute to the development of powerful blood-based tests for CRC screening in the future. PMID- 29184446 TI - Birth weight, sex, and celiac disease: a nationwide twin study. AB - Objective: Earlier research suggests that birth weight may be associated with celiac disease (CD), but the direction of association has been unclear potentially due to confounding effect from genetic and intrafamilial factors. Through within-twin analyses, we aimed to minimize confounding effects such as twins that share genetic and early environmental exposures. Materials and methods: Using the Swedish Twin Registry, we examined the birth weight of 146,830 twins according to the CD status. CD was defined as having villous atrophy according to a small intestinal biopsy reports. Results: The prevalence of diagnosed CD was 0.5% (n=669), and we included 407 discordant pairs of CD-non-CD twins. Comparing the 669 CD patients with non-CD twins, the association between birth weight and future CD was not statistically significant (odds ratio [OR] per 1000 g increase in birth weight: 1.16; 95% confidence interval [CI]=0.97-1.38). In males, the association was positive and statistically significant (OR=1.50; 95% CI=1.11-2.02). However, the association was not significant in within-pair analyses for both dizygotic and monozygotic twins and for both sexes. Conclusion: This population-based study found that in male twins, higher birth weight was associated with higher risk of CD. However, when comparing discordant twin pairs in within-twin pair analyses, there was no statistically significant association between birth weight, intrauterine growth, and future risk of CD. PMID- 29184447 TI - Aseptic-avascular osteonecrosis: local "silent inflammation" in the jawbone and RANTES/CCL5 overexpression. AB - Of the definitions listed in the International Statistical Classification of Diseases and Related Health Problems, tenth revision (ICD-10), two disease descriptions can be found together: "idiopathic aseptic bone necrosis" and "avascular bone necrosis." The relevant literature on both the conditions abbreviates both as "aseptic ischemic osteonecrosis in the jawbone" (AIOJ). To shed light on the clinical details of this condition, osteolytic jawbone samples of 24 patients with different systemic immunological diseases were examined using four steps: presurgical dental X-ray, postsurgical histology, polymerase chain reaction DNA analysis (PCR DNA) of bacteria, and RANTES/CCL5 (R/C) expression. These four steps showed that neither X-ray nor histology delivered unambiguous results with respect to inflammatory processes; furthermore, the PCR results did not show evidence of any microbial load within the jaw samples. However, there is a striking, coherent overexpression of chemokine R/C in the AIOJ samples. This study proved the aseptic existence of "silent inflammation" within the jawbone. The ICD-10 (AIOJ) definition, which is hard to interpret, can now be substantiated with clinical evidence, while the cytokine expressions described in this report can explain the systemic immunological effects observed within the group of examined patients. PMID- 29184448 TI - Older adults and high-risk medication administration in the emergency department. AB - Background: Older adults are susceptible to adverse effects from opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), and benzodiazepines (BZDs). We investigated factors associated with the administration of elevated doses of these medications of interest to older adults (>=65 years old) in the emergency department (ED). Patients and methods: ED records were queried for the administration of medications of interest to older adults at two academic medical center EDs over a 6-month period. Frequency of recommended versus elevated ("High doses" were defined as doses that ranged between 1.5 and 3 times higher than the recommended starting doses; "very high doses" were defined as higher than high doses) starting doses of medications, as determined by geriatric pharmacy/medicine guidelines and expert consensus, was compared by age groups (65 69, 70-74, 75-79, 80-84, and >=85 years), gender, and hospital. Results: There were 17896 visits representing 11374 unique patients >65 years of age (55.3% men, 44.7% women). A total of 3394 doses of medications of interest including 1678 high doses and 684 very high doses were administered to 1364 different patients. Administration of elevated doses of medications was more common than that of recommended doses. Focusing on opioids and BZDs, the 65-69-year age group was much more likely to receive very high doses (1481 and 412 doses, respectively) than the >=85-year age groups (relative risk [RR] 5.52, 95% CI 2.56-11.90), mainly reflecting elevated opioid dosing (RR 8.28, 95% CI 3.69-18.57). Men were more likely than women to receive very high doses (RR 1.47, 95% CI 1.26-1.72), primarily due to BZDs (RR 2.12, 95% CI 2.07-2.16). Conclusion: Administration of elevated doses of opioids and BZDs in the older population occurs frequently in the ED, especially to the 65-69-year age group and men. Further attention to potentially unsafe dosing of high-risk medications to older adults in the ED is warranted. PMID- 29184450 TI - Coexisting multiple myeloma, lymphoma, and non-small cell lung cancer: a case report and review of the literature. AB - Multiple myeloma is a plasma cell dyscrasia characterized by neoplastic proliferation of plasma cells, producing a monoclonal immunoglobulin. Small lymphocytic lymphoma (SLL) is a neoplasm consisting of monoclonal B-cell lymphocyte proliferation. We present an extremely rare case of coexisting multiple myeloma, SLL, and squamous cell carcinoma of the lung in a 74-year-old female patient. She initially presented with a midline mass with pain in the lumbar area. Debulking surgery was performed, and pathology showed plasmacytoma. Further evaluation revealed coexistent IgG kappa myeloma. Imaging revealed extensive abdominal lymphadenopathy, and mesenteric lymph node biopsy confirmed the presence of SLL. The patient was also found to have a mass in the left lower lobe of the lung; biopsy showed squamous cell carcinoma. This patient was treated with lenalidomide and dexamethasone for multiple myeloma, and stereotactic body radiotherapy for limited stage lung cancer. Due to the more indolent course of SLL, watchful waiting was applied. PMID- 29184451 TI - Population pharmacokinetics of pomalidomide in patients with relapsed or refractory multiple myeloma with various degrees of impaired renal function. AB - Pomalidomide is an immunomodulatory drug for treatment of relapsed or refractory multiple myeloma (rrMM) in patients who often have comorbid renal conditions. To assess the impact of renal impairment on pomalidomide exposure, a population pharmacokinetics (PPK) model of pomalidomide in rrMM patients with various degrees of impaired renal function was developed. Intensive and sparse pomalidomide concentration data collected from two clinical studies in rrMM patients with normal renal function, moderately impaired renal function, severely impaired renal function not requiring dialysis, and with severely impaired renal function requiring dialysis were pooled over the dose range of 2 to 4 mg, to assess specifically the influence of the impaired renal function as a categorical variable and a continuous variable on pomalidomide clearance and plasma exposure. In addition, pomalidomide concentration data collected on dialysis days from both the withdrawal (arterial) side and from the returning (venous) side of the dialyzer, from rrMM patients with severely impaired renal function requiring dialysis, were used to assess the extent to which dialysis contributes to the removal of pomalidomide from blood circulation. PPK analyses demonstrated that moderate to severe renal impairment not requiring dialysis has no influence on pomalidomide clearance or plasma exposure, as compared to those patients with normal renal function, while pomalidomide exposure increased approximately 35% in patients with severe renal impairment requiring dialysis on nondialysis days. In addition, dialysis increased total body pomalidomide clearance from 5 L/h to 12 L/h, indicating that dialysis will significantly remove pomalidomide from the blood circulation. Thus, pomalidomide should be administered post-dialysis on the days of dialysis. PMID- 29184449 TI - Diabetes, metabolic syndrome and dyslipidemia in people living with HIV in Africa: re-emerging challenges not to be forgotten. AB - Background: The current challenge in managing people living with human immunodeficiency virus (PLWHIV) includes the identification and monitoring for comorbid health risks associated with HIV and its treatment and longer survival. Dyslipidemia, diabetes mellitus and metabolic syndrome are increasingly seen in PLWHIV. Objective: In this narrative review, we aimed to summarize the current knowledge about diabetes, dyslipidemia and metabolic syndrome in PLWHIV in Africa and also to discuss the challenges that patients as well as health authorities in Africa may face. Methods: PubMed and Google scholar published-English literatures concerning earlier mentioned entities regardless of time limit were critically reviewed. Results: The prevalence of metabolic disorders in HIV population in Africa was estimated to range from 2.1% to 26.5% for diabetes and 20.2% to 43.5% for pre-diabetes, 13% to 58% for metabolic syndrome and 13% to 70% for dyslipidemia. Conclusion: The management of metabolic disorders and cardiovascular disease risks related to HIV is complex especially in Africa due to healthcare resources, but our experience suggests that metabolic clinic is beneficial to patients and staff and should be an important part of HIV services especially as the older HIV population is increasing. In this context, cardiovascular risk assessment of HIV-infected patients will become an important component of care in developing countries in Africa and strategies are needed to deal with progressive increase in the epidemic of type 2 diabetes, dyslipidemia and metabolic syndrome. PMID- 29184452 TI - Violence toward health workers in Bahrain Defense Force Royal Medical Services' emergency department. AB - Background: Employees working in emergency departments (EDs) in hospital settings are disproportionately affected by workplace violence as compared to those working in other departments. Such violence results in minor or major injury to these workers. In other cases, it leads to physical disability, reduced job performance, and eventually a nonconducive working environment for these workers. Materials and methods: A cross-sectional exploratory questionnaire was used to collect data used for the examination of the incidents of violence in the workplace. This study was carried out at the ED of the Bahrain Defense Force (BDF) Hospital. Participants for the study were drawn from nurses, support staff, and emergency physicians. Both male and female workers were surveyed. Results: The study included responses from 100 staff in the ED of the BDF Hospital in Bahrain (doctors, nurses, and support personnel). The most experienced type of violence in the workers in the past 12 months in this study was verbal abuse, which was experienced by 78% of the participants, which was followed by physical abuse (11%) and then sexual abuse (3%). Many cases of violence against ED workers occurred during night shifts (53%), while physical abuse was reported to occur during all the shifts; 40% of the staff in the ED of the hospital were not aware of the policies against workplace violence, and 26% of the staff considered leaving their jobs at the hospital. Conclusion: This study reported multiple findings on the number of workplace violence incidents, as well as the characteristics and factors associated with violence exposure in ED staff in Bahrain. The results clearly demonstrate the importance of addressing the issue of workplace violence in EDs in Bahrain and can be used to demonstrate the strong need for interventions.

AB - Objective: Patients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) are at increased risk of cardiovascular disease (CVD). As sedentary behavior and lack of physical activity are known cardiovascular risk factors, we compared habitual activity between SLE patients, RA patients, and healthy control participants. Patients and methods: For this cross-sectional study, RA and SLE patients were recruited from rheumatology clinics at an academic medical center from April 2013 to December 2014. Healthy control participants were recruited through local advertising during the same time period. Habitual activity was measured using a triaxial accelerometer worn during waking hours for 7 consecutive days. Minutes per day of sedentary, light, and moderate-vigorous physical activity (MVPA) were recorded and compared between SLE, RA, and healthy participants using ANOVA. Results: There were 59 participants included in the analysis: 20 SLE patients, 19 RA patients, and 20 healthy controls. Disease activity was quiescent in both the SLE and RA groups. All three groups demonstrated high sedentary behavior (mean +/- SD sedentary time for all participants: 10.1+/-1.3 hours/day; 76.4% total wear time). There were no significant differences between SLE, RA, and healthy participants in time spent in sedentary behavior (p=0.80) or light activity (p=0.17). Total MVPA (mean +/- SD, minutes/day) was significantly lower in SLE (34.5+/-22.7; p<0.001) and RA (41.5+/-21.3; p=0.005) patients compared to controls (64.9+/-22.4). Conclusion: SLE and RA patients demonstrate suboptimal MVPA despite well-controlled disease. Given their increased CVD risk, effective interventions are required to improve habitual physical activity levels in both populations. PMID- 29184454 TI - Sleep quality and circadian rhythm disruption in the intensive care unit: a review. AB - Sleep and circadian rhythm are reported to be severely abnormal in critically ill patients. Disturbed sleep can lead to the development of delirium and, as a result, can be associated with prolonged stay in the intensive care unit (ICU) and increased mortality. The standard criterion method of sleep assessment, polysomnography (PSG), is complicated in critically ill patients due to the practical challenges and interpretation difficulties. Several PSG sleep studies in the ICU reported the absence of normal sleep characteristics in many critically ill patients, making the standard method of sleep scoring insufficient in this patient group. Watson et al proposed a modified classification for sleep scoring in critically ill patients. This classification has not yet been validated. Sleep disturbance in the ICU is a multifactorial problem. The ICU environment, mechanical ventilation, medication, as well as the critical illness itself have been reported as important sleep disturbing factors. Secretion of sleep hormone, melatonin, expressing circadian rhythmicity was found abolished or phase delayed in critically ill patients. Various interventions have been tested in several studies aiming to improve sleep quality and circadian rhythm in the ICU. The results of these studies were inconclusive due to using the sleep assessment methods other than PSG or the absence of a reliable sleep scoring tool for the analysis of the PSG findings in this patient population. Development of a valid sleep scoring classification is essential for further sleep research in critically ill patients.

AB - The measurement of patient-reported outcome measures (PROMs) following head and neck cancer (HNC) has the capacity to substantially enhance the care of patients and their care-givers following the diagnosis and treatment of HNC. Literature concerning PROMs has increased exponentially in the past 2 decades, producing a vast array of data upon which the multidisciplinary team can reflect. For this review, "Handle On QOL" has been used as a source of references to illustrate the points raised. PROMs are contextualized by considering the clinically-distinct key stages that cancer patients endure: diagnosis, treatment, acute toxicity, early recovery, late effects, recurrence, and palliation. The PROMs are considered in six main categories: 1) those addressing cornucopia of issues not specific to cancer; 2) those addressing issues common to all cancers; 3) questionnaires with items specific to HNC; 4) questionnaires that focus on a particular aspect of head and neck function; 5) those measuring psychological concerns, such as depression, anxiety, or self-esteem; and 6) item prompt lists. Potential benefits of PROMs in clinical practice are discussed, as are barriers to use. The way forward in integrating PROMs into routine HNC care is discussed with an emphasis on information technology. PMID- 29184456 TI - Validating the Patient Experience with Treatment and Self-Management (PETS), a patient-reported measure of treatment burden, in people with diabetes. AB - Aims: To validate a comprehensive general measure of treatment burden, the Patient Experience with Treatment and Self-Management (PETS), in people with diabetes. Methods: We conducted a secondary analysis of a cross-sectional survey study with 120 people diagnosed with type 1 or type 2 diabetes and at least one additional chronic illness. Surveys included established patient-reported outcome measures and a 48-item version of the PETS, a new measure comprised of multi-item scales assessing the burden of chronic illness treatment and self-care as it relates to nine domains: medical information, medications, medical appointments, monitoring health, interpersonal challenges, health care expenses, difficulty with health care services, role activity limitations, and physical/mental exhaustion from self-management. Internal reliability of PETS scales was determined using Cronbach's alpha. Construct validity was determined through correlation of PETS scores with established measures (measures of chronic condition distress, medication satisfaction, self-efficacy, and global well being), and known-groups validity through comparisons of PETS scores across clinically distinct groups. In an exploratory test of predictive validity, step wise regressions were used to determine which PETS scales were most associated with outcomes of chronic condition distress, overall physical and mental health, and medication adherence. Results: Respondents were 37-88 years old, 59% female, 29% non-white, and 67% college-educated. PETS scales showed good reliability (Cronbach's alphas >=0.74). Higher PETS scale scores (greater treatment burden) were correlated with more chronic condition distress, less medication convenience, lower self-efficacy, and worse general physical and mental health. Participants less (versus more) adherent to medications and those with more (versus fewer) health care financial difficulties had higher mean PETS scores. Medication burden was the scale that was most consistently associated with well being and patient-reported adherence. Conclusion: The PETS is a reliable and valid measure for assessing perceived treatment burden in people coping with diabetes.

AB - A review of the European Union (EU) regulations concerning blood, tissues, and cells of human origin is under way in the EU. From the ethical point of view, the non-remuneration of donations and the ban on deriving gain from human biological materials are of particular significance. While the basic ethical principles involved in the procurement, preservation, and use of these materials are the same, their practical application should be adapted to the specific context of each material. In the case of donation and use of blood, in particular, the issue of legitimate reimbursements to donors and for transfusion centers has to be managed in accordance with the principle of non-commercialization. There is also a need for strict rules to avoid possible commercial spillover effects from blood derived products. The author proposes ethical criteria regarding reimbursements to donors, costs associated with processing, and the development (and possible marketing) of products. PMID- 29184460 TI - Understanding of evaluation capacity building in practice: a case study of a national medical education organization. AB - Introduction: Evaluation capacity building (ECB) is a topic of great interest to many organizations as they face increasing demands for accountability and evidence-based practices. ECB is about building the knowledge, skills, and attitudes of organizational members, the sustainability of rigorous evaluative practices, and providing the resources and motivations to engage in ongoing evaluative work. There exists a solid foundation of theoretical research on ECB, however, understanding what ECB looks like in practice is relatively thin. Our purpose was to investigate what ECB looks like firsthand within a national medical educational organization. Methods: The context for this study was the Acute Critical Events Simulation (ACES) organization in Canada, which has successfully evolved into a national educational program, driven by physicians. We conducted an exploratory qualitative study to better understand and describe ECB in practice. In doing so, interviews were conducted with program leaders and instructors so as to gain a richer understanding of evaluative processes and practices. Results: A total of 21 individuals participated in the semistructured interviews. Themes from our qualitative data analysis included the following: evaluation knowledge, skills, and attitudes, use of evaluation findings, shared evaluation beliefs and commitment, evaluation frameworks and processes, and resources dedicated to evaluation. Conclusion: The national ACES organization was a useful case study to explore ECB in practice. The ECB literature provided a solid foundation to understand the purpose and nuances of ECB. This study added to the paucity of studies focused on examining ECB in practice. The most important lesson learned was that the organization must have leadership who are intrinsically motivated to employ and use evaluation data to drive ongoing improvements within the organization. Leaders who are intrinsically motivated will employ risk taking when evaluation practices and processes may be somewhat unfamiliar. Creating and maintaining a culture of data use and ongoing inquiry have enabled national ACES to achieve a sustainable evaluation practice. PMID- 29184459 TI - Simulation in bronchoscopy: current and future perspectives. AB - Objective: To provide an overview of current literature that informs how to approach simulation practice of bronchoscopy and discuss how findings from other simulation research can help inform the use of simulation in bronchoscopy training. Summary: We conducted a literature search on simulation training of bronchoscopy and divided relevant studies in three categories: 1) structuring simulation training in bronchoscopy, 2) assessment of competence in bronchoscopy training, and 3) development of cheap alternatives for bronchoscopy simulation. Conclusion: Bronchoscopy simulation is effective, and the training should be structured as distributed practice with mastery learning criteria (ie, training until a certain level of competence is achieved). Dyad practice (training in pairs) is possible and may increase utility of available simulators. Trainee performance should be assessed with assessment tools with established validity. Three-dimensional printing is a promising new technology opening possibilities for developing cheap simulators with innovative features.

AB - Systemic juvenile idiopathic arthritis (SJIA) is a disease marked with arthritis and several features of systemic inflammation including fevers, rashes, hepatosplenomegaly, lymphadenopathy, and serositis. The presentation can be variable and arthritis can be a later feature. Macrophage activation syndrome can be a life-threatening complication of this illness and requires early recognition and prompt therapy. Advancements in understanding the biology of SJIA have led to the development of cytokine-targeted therapies, mainly interleukin-1 (IL-1) and IL-6 inhibitors that have significantly improved outcomes. In this review, we provide an update on the advances in the understanding of SJIA biology and also the therapeutic options. PMID- 29184462 TI - Rodrigo Oliva Perez, MD, PhD.

AB - Modern rectal cancer management is dependent on preoperative staging, and radiological assessment is a crucial part of this process. Imaging must provide sufficient information to guide preoperative decision-making that is reliable and reproducible. Different methods have been used for local staging; however, magnetic resonance imaging (MRI) has shown to be the most reliable tool for this purpose. MRI offers prognostic information about the patients and guides the decision between neoadjuvant treatment and total mesorectal excision alone. Also, not only the initial staging but also restaging by MRI can provide significant information regarding tumor response that is essential when considering alternative approaches. PMID- 29184467 TI - The Perfect Total Mesorectal Excision Obviates the Need for Anything Else in the Management of Most Rectal Cancers. AB - This article discusses the local control of primary rectal cancer and its locoregional spread in the light of modern advances. In recent years, the use of neoadjuvant chemoradiation has spread widely. However, its true benefit is not always balanced with its morbidities. Often total mesorectal excision (TME) is the best option. We will discuss the indications for immediate surgery for chemoradiation in advance and the importance of a delay in the management plan. To understand this selection, it is mandatory to know the true extent of tissue at risk for tumor dissemination and spread. Considering that TME may be enough for many patients and that most local recurrences are failures of surgical technique we introduce a new concept of total mesorectal irradiation. This exploits the new reality that precise, focused neoadjuvant therapy can offer a better response with fewer complications. Together these important changes in cancer board (multidisciplinary team) planning can also offer selected patients complete control of their cancer with no need for surgery. PMID- 29184466 TI - Local Excision and Endoscopic Resections for Early Rectal Cancer. AB - Radical surgery is considered as the standard treatment for rectal cancer. Transanal local excision has been considered an interesting alternative for the management of selected patients with rectal cancers for many decades. Different approaches had been considered for local excision, from endoscopic submucosal dissection to resections using platforms, such as transanal endoscopic microsurgery or transanal minimally invasive surgery. Identifying the ideal candidate for this approach is crucial, as a local failure after local excision is associated with poor outcomes, even for an initial early rectal tumor. In this article, the diagnostic tools and criteria to select patients for local excision, the different modalities used, and the outcomes are discussed. PMID- 29184468 TI - Is There Any Reason Not to Perform Standard Laparoscopic Total Mesorectal Excision? AB - The curative treatment of locally advanced rectal cancer is currently based on chemoradiotherapy and total mesorectal excision (TME). Laparoscopy has developed considerably because of obvious clinical benefits such as reduced pain and shorter hospital stay. Recently, several prospective randomized clinical trials with long-term follow-up have showed that laparoscopy is noninferior to laparotomy with the same oncologic outcomes in terms of survival and local control rate. However, laparoscopic TME remains a challenging procedure requiring a high level of expertise and a long learning curve to ensure an adequate and safe resection. The only relative contraindication of laparoscopic rectal surgery is T4 rectal cancer extended beyond the plane of TME. In this situation, it is reasonable to consider an open resection to avoid an uncomplete resection. In obese and elderly patients, laparoscopic TME also provides the same benefits as in nonobese and younger patients but may be more difficult to achieve. This review summarizes current knowledge on the place of laparoscopic TME in the treatment of rectal cancer. PMID- 29184469 TI - Transanal Total Mesorectal Excision: Why, When, and How. AB - Transanal total mesorectal excision (taTME) has evolved over the past decade fueled by advances in minimally invasive surgery. The technique aims to overcome the constraints posed by a narrow rigid pelvis and poor TME visualization that are encountered during "top-down" rectal surgery. A more accurate pelvic dissection should subsequently result in safer oncological resections and better preservation of pelvic autonomic nerves. taTME is an advanced complex technique that requires dedicated training and experience in TME surgery. Initial results from small cohorts are promising and confirmation by randomized controlled trials is eagerly awaited. PMID- 29184470 TI - Is There Any Reason to Still Consider Lateral Lymph Node Dissection in Rectal Cancer? Rationale and Technique. AB - Nodal dissemination in locally advanced rectal cancer occurs mainly in two directions: upward and lateral. Lateral node involvement has been demonstrated; however, lateral lymph node dissection (LLND) is not routinely performed in Western countries and the focus is more on neoadjuvant treatment regimens. The main reasons for this are the high morbidity associated with the operation and the uncertain oncological benefit. There is, however, recent evidence that in selected cases, neoadjuvant treatment combined with total mesorectal excision only might not be sufficient. In this article, the historical developments in the East and the West, the current evidence regarding lateral nodal disease, and the surgical steps in the LLND are discussed. PMID- 29184471 TI - Abdominoperineal Excision: Technical Challenges in Optimal Surgical and Oncological Outcomes after Abdominoperineal Excision for Rectal Cancer. AB - Treatment results in rectal cancer have improved significantly during the recent two decades, but local control and survival after abdominoperineal excision (APE) have not improved to the same degree as that seen after anterior resection (AR). The reason for this is an increased risk of inadvertent bowel perforations and tumor involved margins after APE as compared with AR. The conventional synchronous combined APE has not been a standardized procedure and consequently oncological outcomes have varied considerably between different institutions and in different reports. With the new concept of APE, based on well-defined anatomical structures, the procedure can be categorized as intersphincteric APE, extralevator APE, and ischioanal APE. This article discusses the technical aspects and results from this approach. PMID- 29184472 TI - Intersphincteric Resection Pushing the Envelope for Sphincter Preservation. AB - During the last 15 years, a significant evolution has emerged in the surgical treatment of rectal cancer and restoration of bowel continuity has been one of the main goals. For many years the treatment of distal rectal cancer would necessarily require an abdominoperineal resection and end colostomy. The surgical procedure of intersphincteric resection has been proposed to offer sphincter preservation in patients with low rectal cancer and has been legitimized if executed according to adequate oncologic criteria. This article will discuss the best indications, technical aspects, functional, and oncological outcomes of intersphicteric resection in the management of rectal cancer. PMID- 29184473 TI - Neoadjuvant Treatment Strategies: Advanced Radiation Alternatives. AB - Long-course chemoradiation therapy (CRT) has been the standard approach for locally advanced rectal tumors. Neoadjuvant CRT is associated to improved local disease control, with less toxicity when compared with adjuvant CRT, as well as the chance for pathologic complete response. The CRT regimens have improved over the past years. This article will examine selected controversies, including novel chemoradiation regimens, duration of radiation (short vs. long course), and radiation techniques such as intensity-modulated radiation therapy (IMRT). PMID- 29184474 TI - Neoadjuvant Strategies: Locally Advanced Rectal Cancer. AB - Colorectal cancer is one of the major leading causes of death in both men and women. The successful management of colon or rectal cancer demands a multidisciplinary approach. In the last few years, significant improvement has been noticed in the management of localized rectal cancer to reduce local recurrence and obtain complete pathological response following appropriate surgical steps, if necessary. Implementation of neoadjuvant therapy not only enhances disease control, it may also ensure sphincter preserving procedures or organ-preserving options. This article principally concentrates on the current neoadjuvant treatment for locally advanced rectal cancer and the prognostic outcomes of such therapy, including a discussion on the historical perspective. PMID- 29184475 TI - Management of the Complete Clinical Response. AB - Organ preservation is considered in the management of selected patients with rectal cancer. Complete clinical response observed after neoadjuvant chemoradiation for rectal cancer is one of these cases. Patients who present complete clinical response are candidates to the watch-and-wait approach, when radical surgery is not immediately performed and is offered only to patients in the event of a local relapse. These patients are included in a strict follow-up, and up of 70% of them will never be operated during the follow-up. This strategy is associated with similar oncological outcomes as patients operated on, and the advantage of avoiding the morbidity associated to the radical operation. In this article we will discuss in detail the best candidates for this approach, the protocol itself, and the long-term outcomes. PMID- 29184476 TI - Organ-Preserving Strategies for the Management of Near-Complete Responses in Rectal Cancer after Neoadjuvant Chemoradiation. AB - In recent years, organ preservation has been considered a feasible alternative to total mesorectal excision for patients with locally advanced rectal cancer with a clinical complete response to neoadjuvant therapy. However, the degree of tumor response to neoadjuvant therapy is variable. A fraction of the patients who did not achieve a complete response had grossly visible tumors. These patients, with clearly incomplete clinical response, need a total mesorectal excision. In addition, some patients with a significant tumor response still have some abnormalities in the bowel wall, such as superficial ulceration or tissue nodularity, which, while not conclusive for the presence of a tumor, are indicative of the possibility of a residual tumor in the bowel wall or in mesorectal lymph nodes. The management of patients with a so-called near-complete clinical response to neoadjuvant therapy is controversial. In this article, we will review the clinical and radiological criteria that define a clinical response to neoadjuvant therapy, possible treatment strategies, and follow-up protocols. We will also discuss patient and tumor characteristics that in our opinion can be useful in selecting the most appropriate treatment alternative. Although organ preservation and quality of life are important, the primary goal of treatment for these patients should be local tumor control and long-term survival. PMID- 29184477 TI - Molecular Biology: Are We Getting Any Closer to Providing Clinically Useful Information? AB - Advances in molecular biology and biomarker research have significantly impacted our understanding and treatment of multiple solid malignancies. In rectal cancer, where neoadjuvant chemoradiation is widely used for locally advanced disease, most efforts have focused on the identification of predictors of response in an attempt to appropriately select patients for multimodality therapy. A variety of biomarkers have been studied, including genetic mutations, chromosomal copy number alterations, and single as well as multigene expression patterns. Also, as transanal resection of rectal tumors requires accurate preoperative detection of lymph node metastasis, the identification of biomarkers of regional nodal involvement has been another important field of active research. While preliminary results have been promising, lack of external validation means has a limited translation to clinical use. This review summarizes recent developments in rectal cancer biomarker research, highlighting the challenges associated with their adoption, and evaluating their potential for clinical use. PMID- 29184479 TI - Visual Sensory Signals Dominate Tactile Cues during Docked Feeding in Hummingbirds. AB - Animals living in and interacting with natural environments must monitor and respond to changing conditions and unpredictable situations. Using information from multiple sensory systems allows them to modify their behavior in response to their dynamic environment but also creates the challenge of integrating different, and potentially contradictory, sources of information for behavior control. Understanding how multiple information streams are integrated to produce flexible and reliable behavior is key to understanding how behavior is controlled in natural settings. Natural settings are rarely still, which challenges animals that require precise body position control, like hummingbirds, which hover while feeding from flowers. Tactile feedback, available only once the hummingbird is docked at the flower, could provide additional information to help maintain its position at the flower. To investigate the role of tactile information for hovering control during feeding, we first asked whether hummingbirds physically interact with a feeder once docked. We quantified physical interactions between docked hummingbirds and a feeder placed in front of a stationary background pattern. Force sensors on the feeder measured a complex time course of loading that reflects the wingbeat frequency and bill movement of feeding hummingbirds, and suggests that they sometimes push against the feeder with their bill. Next, we asked whether the measured tactile interactions were used by feeding hummingbirds to maintain position relative to the feeder. We created two experimental scenarios-one in which the feeder was stationary and the visual background moved and the other where the feeder moved laterally in front of a white background. When the visual background pattern moved, docked hummingbirds pushed significantly harder in the direction of horizontal visual motion. When the feeder moved, and the background was stationary, hummingbirds generated aerodynamic force in the opposite direction of the feeder motion. These results suggest that docked hummingbirds are using visual information about the environment to maintain body position and orientation, and not actively tracking the motion of the feeder. The absence of flower tracking behavior in hummingbirds contrasts with the behavior of hawkmoths, and provides evidence that they rely primarily on the visual background rather than flower-based cues while feeding. PMID- 29184480 TI - Low Cost Electrode Assembly for EEG Recordings in Mice. AB - Wireless electroencephalography (EEG) of small animal subjects typically utilizes miniaturized EEG devices which require a robust recording and electrode assembly that remains in place while also being well-tolerated by the animal so as not to impair the ability of the animal to perform normal living activities or experimental tasks. We developed simple and fast electrode assembly and method of electrode implantation using electrode wires and wire-wrap technology that provides both higher survival and success rates in obtaining recordings from the electrodes than methods using screws as electrodes. The new wire method results in a 51% improvement in the number of electrodes that successfully record EEG signal. Also, the electrode assembly remains affixed and provides EEG signal for at least a month after implantation. Screws often serve as recording electrodes, which require either drilling holes into the skull to insert screws or affixing screws to the surface of the skull with adhesive. Drilling holes large enough to insert screws can be invasive and damaging to brain tissue, using adhesives may interfere with conductance and result in a poor signal, and soldering screws to wire leads results in fragile connections. The methods presented in this article provide a robust implant that is minimally invasive and has a significantly higher success rate of electrode implantation. In addition, the implant remains affixed and produces good recordings for over a month, while using economical, easily obtained materials and skills readily available in most animal research laboratories. PMID- 29184481 TI - Cynefin as Reference Framework to Facilitate Insight and Decision-Making in Complex Contexts of Biomedical Research. AB - The Cynefin scheme is a concept of knowledge management, originally devised to support decision making in management, but more generally applicable to situations, in which complexity challenges the quality of insight, prediction, and decision. Despite the fact that life itself, and especially the brain and its diseases, are complex to the extent that complexity could be considered their cardinal feature, complex problems in biomedicine are often treated as if they were actually not more than the complicated sum of solvable sub-problems. Because of the emergent properties of complex contexts this is not correct. With a set of clear criteria Cynefin helps to set apart complex problems from "simple/obvious," "complicated," "chaotic," and "disordered" contexts in order to avoid misinterpreting the relevant causality structures. The distinction comes with the insight, which specific kind of knowledge is possible in each of these categories and what are the consequences for resulting decisions and actions. From student's theses over the publication and grant writing process to research politics, misinterpretation of complexity can have problematic or even dangerous consequences, especially in clinical contexts. Conceptualization of problems within a straightforward reference language like Cynefin improves clarity and stringency within projects and facilitates communication and decision-making about them. PMID- 29184478 TI - Visual Prosthesis: Interfacing Stimulating Electrodes with Retinal Neurons to Restore Vision. AB - The bypassing of degenerated photoreceptors using retinal neurostimulators is helping the blind to recover functional vision. Researchers are investigating new ways to improve visual percepts elicited by these means as the vision produced by these early devices remain rudimentary. However, several factors are hampering the progression of bionic technologies: the charge injection limits of metallic electrodes, the mechanical mismatch between excitable tissue and the stimulating elements, neural and electric crosstalk, the physical size of the implanted devices, and the inability to selectively activate different types of retinal neurons. Electrochemical and mechanical limitations are being addressed by the application of electromaterials such as conducting polymers, carbon nanotubes and nanocrystalline diamonds, among other biomaterials, to electrical neuromodulation. In addition, the use of synthetic hydrogels and cell-laden biomaterials is promising better interfaces, as it opens a door to establishing synaptic connections between the electrode material and the excitable cells. Finally, new electrostimulation approaches relying on the use of high-frequency stimulation and field overlapping techniques are being developed to better replicate the neural code of the retina. All these elements combined will bring bionic vision beyond its present state and into the realm of a viable, mainstream therapy for vision loss. PMID- 29184482 TI - Identification of Candidate Allosteric Modulators of the M1 Muscarinic Acetylcholine Receptor Which May Improve Vagus Nerve Stimulation in Chronic Tinnitus. AB - Chronic tinnitus is characterized by neuroplastic changes of the auditory cortex. A promising method for therapy of chronic tinnitus is vagus nerve stimulation (VNS) combined with auditory stimulation. The principle of VNS is reversal of pathological neuroplastic changes of the auditory cortex toward physiological neural activity and synchronicity. The VNS mechanism of action in chronic tinnitus patients is prevailingly through the muscarinic neuromodulation of the auditory cortex by the activation of nc. basalis Meynerti. The aim of this study is to propose potential pharmaceutics which may improve the neuromodulatory effects of VNS. The working hypothesis is that M1 receptors have a dominant role in the neural plasticity of the auditory cortex. We propose that allosteric agonists of the muscarinic receptor type 1 (M1) receptor could improve specificity and selectivity of the neuromodulatory effect of VNS on the auditory cortex of chronic tinnitus patients even in the circumstances of lower acetylcholine brain concentration. This intervention would also reinforce the re learning process of tinnitus (sub)networks by acting on cholinergic memory and learning mechanisms. We performed in silico screening of drug space using the EIIP/AQVN filter and selected 50 drugs as candidates for allosteric modulators of muscarinic receptors. Further filtering of these compounds by means of 3D QSAR and docking revealed 3 approved drugs-bromazepam, estazolam and flumazenil as the most promising candidates for combined chronic tinnitus therapy. These drugs should be further evaluated by biological tests and clinical trials. PMID- 29184483 TI - H3K9ac and HDAC2 Activity Are Involved in the Expression of Monocarboxylate Transporter 1 in Oligodendrocyte. AB - Recently, it is reported that monocarboxylate transporter 1 (MCT1) plays crucial role in oligodendrocyte differentiation and myelination. We found that MCT1 is strongly expressed in oligodendrocyte but weakly expressed in oligodendrocyte precursors (OPCs), and the underlying mechanisms remain elusive. Histone deacetylases (HDACs) activity is required for induction of oligodendrocyte differentiation and maturation. We asked whether HDACs are involved in the regulation of MCT1 expression. This work revealed that the acetylation level of histone H3K9 (H3K9ac) was much higher in mct1 gene (Slc16a1) promoter in OPCs than that in oligodendrocyte. H3K9ac regulates MCT1 expression was confirmed by HDAC acetyltransferase inhibitors trichostatin A and curcumin. Of note, there was a negative correlation between H3K9ac and MCT1 expression in oligodendrocyte. Further, we found that the levels of HDAC1, 2, and 3 protein in oligodendrocyte were obviously higher than those in OPCs. However, specific knockdown of HDAC2 but not HDAC1 and HDAC3 significantly decreased the expression of MCT1 in oligodendrocyte. Conversely, overexpression of HDAC2 remarkably enhanced the expression of MCT1. The results imply that HDAC2 is involved in H3K9ac modification which regulates the expression of MCT1 during the development of oligodendrocyte. PMID- 29184485 TI - Globular Adiponectin Limits Microglia Pro-Inflammatory Phenotype through an AdipoR1/NF-kappaB Signaling Pathway. AB - We recently reported that increased levels of Adiponectin (ApN) in the brain led to microglia phenotype and activation state regulation, thus reducing both global brain inflammation and depressive-like behaviors in mice. Apart from this, little is known on ApN molecular effects on microglia, although these cells are crucial in both physiological and pathological processes. Here we fill this gap by studying the effects and targets of ApN toward neuroinflammation. Our findings suggest that ApN deficiency in mice leads to a higher sensitivity of mice to neuroinflammation that is due to enhanced microglia responsiveness to a pro inflammatory challenge. Moreover, we show that globular ApN (gApN) exerts direct in vivo anti-inflammatory actions on microglia by reducing IL-1beta, IL-6, and TNFalpha synthesis. In vitro, gApN anti-inflammatory properties are confirmed in brain-sorted microglia, primary cultured and microglia cell line (BV2), but are not observed on astrocytes. Our results also show that gApN blocks LPS-induced nitrosative and oxidative stress in microglia. Finally, we demonstrate for the first time that these anti-inflammatory and anti-oxidant actions of gApN on microglia are mediated through an AdipoR1/NF-kappaB signaling pathway.

AB - The dentate gyrus (DG) is a unique structure of the hippocampus that is distinguished by ongoing neurogenesis throughout the lifetime of an organism. The development of the DG, which begins during late gestation and continues during the postnatal period, comprises the structural formation of the DG as well as the establishment of the adult neurogenic niche in the subgranular zone (SGZ). We investigated the time course of postnatal maturation of the DG in male C57BL/6J mice and male Sprague-Dawley rats based on the distribution patterns of the immature neuronal marker doublecortin (DCX) and a marker for mature neurons, calbindin (CB). Our findings demonstrate that the postnatal DG is marked by a substantial maturation with a high number of DCX-positive granule cells (GCs) during the first two postnatal weeks followed by a progression toward more mature patterns and increasing numbers of CB-positive GCs within the subsequent 2 weeks. The most substantial shift in maturation of the GC population took place between P7 and P14 in both mice and rats, when young, immature DCX-positive GCs became confined to the innermost part of the GC layer (GCL), indicative of the formation of the SGZ. These results suggest that the first month of postnatal development represents an important transition phase during which DG neurogenesis and the maturation course of the GC population becomes analogous to the process of adult neurogenesis. Therefore, the postnatal DG could serve as an attractive model for studying a growing and functionally maturing neural network. Direct comparisons between mice and rats revealed that the transition from immature DCX-positive to mature CB-positive GCs occurs more rapidly in the rat by approximately 4-6 days. The remarkable species difference in the speed of maturation on the GC population level may have important implications for developmental and neurogenesis research in different rodent species and strains. PMID- 29184484 TI - Ketone-Based Metabolic Therapy: Is Increased NAD+ a Primary Mechanism? AB - The ketogenic diet's (KD) anticonvulsant effects have been well-documented for nearly a century, including in randomized controlled trials. Some patients become seizure-free and some remain so after diet cessation. Many recent studies have explored its expanded therapeutic potential in diverse neurological disorders, yet no mechanism(s) of action have been established. The diet's high fat, low carbohydrate composition reduces glucose utilization and promotes the production of ketone bodies. Ketone bodies are a more efficient energy source than glucose and improve mitochondrial function and biogenesis. Cellular energy production depends on the metabolic coenzyme nicotinamide adenine dinucleotide (NAD), a marker for mitochondrial and cellular health. Furthermore, NAD activates downstream signaling pathways (such as the sirtuin enzymes) associated with major benefits such as longevity and reduced inflammation; thus, increasing NAD is a coveted therapeutic endpoint. Based on differential NAD+ utilization during glucose- vs. ketone body-based acetyl-CoA generation for entry into the tricarboxylic cycle, we propose that a KD will increase the NAD+/NADH ratio. When rats were fed ad libitum KD, significant increases in hippocampal NAD+/NADH ratio and blood ketone bodies were detected already at 2 days and remained elevated at 3 weeks, indicating an early and persistent metabolic shift. Based on diverse published literature and these initial data we suggest that increased NAD during ketolytic metabolism may be a primary mechanism behind the beneficial effects of this metabolic therapy in a variety of brain disorders and in promoting health and longevity. PMID- 29184487 TI - The Role of Celestial Compass Information in Cataglyphis Ants during Learning Walks and for Neuroplasticity in the Central Complex and Mushroom Bodies. AB - Central place foragers are faced with the challenge to learn the position of their nest entrance in its surroundings, in order to find their way back home every time they go out to search for food. To acquire navigational information at the beginning of their foraging career, Cataglyphis noda performs learning walks during the transition from interior worker to forager. These small loops around the nest entrance are repeatedly interrupted by strikingly accurate back turns during which the ants stop and precisely gaze back to the nest entrance presumably to learn the landmark panorama of the nest surroundings. However, as at this point the complete navigational toolkit is not yet available, the ants are in need of a reference system for the compass component of the path integrator to align their nest entrance-directed gazes. In order to find this directional reference system, we systematically manipulated the skylight information received by ants during learning walks in their natural habitat, as it has been previously suggested that the celestial compass, as part of the path integrator, might provide such a reference system. High-speed video analyses of distinct learning walk elements revealed that even exclusion from the skylight polarization pattern, UV-light spectrum and the position of the sun did not alter the accuracy of the look back to the nest behavior. We therefore conclude that C. noda uses a different reference system to initially align their gaze directions. However, a comparison of neuroanatomical changes in the central complex and the mushroom bodies before and after learning walks revealed that exposure to UV light together with a naturally changing polarization pattern was essential to induce neuroplasticity in these high-order sensory integration centers of the ant brain. This suggests a crucial role of celestial information, in particular a changing polarization pattern, in initially calibrating the celestial compass system. PMID- 29184488 TI - Brain Maturation, Cognition and Voice Pattern in a Gender Dysphoria Case under Pubertal Suppression. AB - Introduction: Gender dysphoria (GD) (DMS-5) is a condition marked by increasing psychological suffering that accompanies the incongruence between one's experienced or expressed gender and one's assigned gender. Manifestation of GD can be seen early on during childhood and adolescence. During this period, the development of undesirable sexual characteristics marks an acute suffering of being opposite to the sex of birth. Pubertal suppression with gonadotropin releasing hormone analogs (GnRHa) has been proposed for these individuals as a reversible treatment for postponing the pubertal development and attenuating psychological suffering. Recently, increased interest has been observed on the impact of this treatment on brain maturation, cognition and psychological performance. Objectives: The aim of this clinical report is to review the effects of puberty suppression on the brain white matter (WM) during adolescence. WM Fractional anisotropy, voice and cognitive functions were assessed before and during the treatment. MRI scans were acquired before, and after 22 and 28 months of hormonal suppression. Methods: We performed a longitudinal evaluation of a pubertal transgender girl undergoing hormonal treatment with GnRH analog. Three longitudinal magnetic resonance imaging (MRI) scans were performed for diffusion tensor imaging (DTI), regarding Fractional Anisotropy (FA) for regions of interest analysis. In parallel, voice samples for acoustic analysis as well as executive functioning with the Wechsler Intelligence Scale (WISC-IV) were performed. Results: During the follow-up, white matter fractional anisotropy did not increase, compared to normal male puberty effects on the brain. After 22 months of pubertal suppression, operational memory dropped 9 points and remained stable after 28 months of follow-up. The fundamental frequency of voice varied during the first year; however, it remained in the female range. Conclusion: Brain white matter fractional anisotropy remained unchanged in the GD girl during pubertal suppression with GnRHa for 28 months, which may be related to the reduced serum testosterone levels and/or to the patient's baseline low average cognitive performance.Global performance on the Weschler scale was slightly lower during pubertal suppression compared to baseline, predominantly due to a reduction in operational memory. Either a baseline of low average cognition or the hormonal status could play a role in cognitive performance during pubertal suppression. The voice pattern during the follow-up seemed to reflect testosterone levels under suppression by GnRHa treatment. PMID- 29184489 TI - Commentary: The Code for Facial Identity in the Primate Brain. PMID- 29184490 TI - Attractiveness Modulates Neural Processing of Infant Faces Differently in Males and Females. AB - Consistent attention and proper processing of infant faces by adults are essential for infant survival. Previous behavioral studies showed gender differences in processing infant cues (e.g., crying, laughing or facial attractiveness) and more importantly, the efforts invested in nurturing offspring. The underlying neural mechanisms of processing unknown infant faces provide hints for understanding behavioral differences. This functional magnetic resonance imaging (fMRI) study recruited 32 unmarried adult (16 females and 16 males) participants to view unfamiliar infant faces and rate the attractiveness. Adult faces were also included. Behaviorally, despite that females and males showed no differences in attractiveness ratings of infant faces, a positive correlation was found between female's (but not male's) subjective liking for infants and attractiveness ratings of the infant faces. Functionally, brain activations to infant faces were modulated by attractiveness differently in males and females. Specifically, in female participants, activities in the ventromedial prefrontal cortex (vmPFC) and striatum/Nucleus Accumbens (NAcc) were positively modulated by infant facial attractiveness, and the modulation coefficients of these two regions were positively correlated. In male participants, infant facial attractiveness negatively modulated the activity in the dorsomedial prefrontal cortex (dmPFC). Our findings reveal that different neural mechanisms are involved in the processing of infant faces, which might lead to observed behavioral differences between males and females towards the baby. PMID- 29184491 TI - Computational and Experimental Approaches to Visual Aesthetics. AB - Aesthetics has been the subject of long-standing debates by philosophers and psychologists alike. In psychology, it is generally agreed that aesthetic experience results from an interaction between perception, cognition, and emotion. By experimental means, this triad has been studied in the field of experimental aesthetics, which aims to gain a better understanding of how aesthetic experience relates to fundamental principles of human visual perception and brain processes. Recently, researchers in computer vision have also gained interest in the topic, giving rise to the field of computational aesthetics. With computing hardware and methodology developing at a high pace, the modeling of perceptually relevant aspect of aesthetic stimuli has a huge potential. In this review, we present an overview of recent developments in computational aesthetics and how they relate to experimental studies. In the first part, we cover topics such as the prediction of ratings, style and artist identification as well as computational methods in art history, such as the detection of influences among artists or forgeries. We also describe currently used computational algorithms, such as classifiers and deep neural networks. In the second part, we summarize results from the field of experimental aesthetics and cover several isolated image properties that are believed to have a effect on the aesthetic appeal of visual stimuli. Their relation to each other and to findings from computational aesthetics are discussed. Moreover, we compare the strategies in the two fields of research and suggest that both fields would greatly profit from a joined research effort. We hope to encourage researchers from both disciplines to work more closely together in order to understand visual aesthetics from an integrated point of view. PMID- 29184492 TI - Functional Brain Imaging Synthesis Based on Image Decomposition and Kernel Modeling: Application to Neurodegenerative Diseases. AB - The rise of neuroimaging in research and clinical practice, together with the development of new machine learning techniques has strongly encouraged the Computer Aided Diagnosis (CAD) of different diseases and disorders. However, these algorithms are often tested in proprietary datasets to which the access is limited and, therefore, a direct comparison between CAD procedures is not possible. Furthermore, the sample size is often small for developing accurate machine learning methods. Multi-center initiatives are currently a very useful, although limited, tool in the recruitment of large populations and standardization of CAD evaluation. Conversely, we propose a brain image synthesis procedure intended to generate a new image set that share characteristics with an original one. Our system focuses on nuclear imaging modalities such as PET or SPECT brain images. We analyze the dataset by applying PCA to the original dataset, and then model the distribution of samples in the projected eigenbrain space using a Probability Density Function (PDF) estimator. Once the model has been built, we can generate new coordinates on the eigenbrain space belonging to the same class, which can be then projected back to the image space. The system has been evaluated on different functional neuroimaging datasets assessing the: resemblance of the synthetic images with the original ones, the differences between them, their generalization ability and the independence of the synthetic dataset with respect to the original. The synthetic images maintain the differences between groups found at the original dataset, with no significant differences when comparing them to real-world samples. Furthermore, they featured a similar performance and generalization capability to that of the original dataset. These results prove that these images are suitable for standardizing the evaluation of CAD pipelines, and providing data augmentation in machine learning systems -e.g. in deep learning-, or even to train future professionals at medical school. PMID- 29184493 TI - Step-to-Step Ankle Inversion/Eversion Torque Modulation Can Reduce Effort Associated with Balance. AB - Below-knee amputation is associated with higher energy expenditure during walking, partially due to difficulty maintaining balance. We previously found that once-per-step push-off work control can reduce balance-related effort, both in simulation and in experiments with human participants. Simulations also suggested that changing ankle inversion/eversion torque on each step, in response to changes in body state, could assist with balance. In this study, we investigated the effects of ankle inversion/eversion torque modulation on balance related effort among amputees (N = 5) using a multi-actuated ankle-foot prosthesis emulator. In stabilizing conditions, changes in ankle inversion/eversion torque were applied so as to counteract deviations in side-to side center-of-mass acceleration at the moment of intact-limb toe off; higher acceleration toward the prosthetic limb resulted in a corrective ankle inversion torque during the ensuing stance phase. Destabilizing controllers had the opposite effect, and a zero gain controller made no changes to the nominal inversion/eversion torque. To separate the balance-related effects of step-to step control from the potential effects of changes in average mechanics, average ankle inversion/eversion torque and prosthesis work were held constant across conditions. High-gain stabilizing control lowered metabolic cost by 13% compared to the zero gain controller (p = 0.05). We then investigated individual responses to subject-specific stabilizing controllers following an enforced exploration period. Four of five participants experienced reduced metabolic rate compared to the zero gain controller (-15, -14, -11, -6, and +4%) an average reduction of 9% (p = 0.05). Average prosthesis mechanics were unchanged across all conditions, suggesting that improvements in energy economy might have come from changes in step-to-step corrections related to balance. Step-to-step modulation of inversion/eversion torque could be used in new, active ankle-foot prostheses to reduce walking effort associated with maintaining balance. PMID- 29184495 TI - Polygalae Radix Extract Prevents Axonal Degeneration and Memory Deficits in a Transgenic Mouse Model of Alzheimer's Disease. AB - Memory impairments in Alzheimer's disease (AD) occur due to degenerated axons and disrupted neural networks. Since only limited recovery is possible after the destruction of neural networks, preventing axonal degeneration during the early stages of disease progression is necessary to prevent AD. Polygalae Radix (roots of Polygala tenuifolia; PR) is a traditional herbal medicine used for sedation and amnesia. In this study, we aimed to clarify and analyze the preventive effects of PR against memory deficits in a transgenic AD mouse model, 5XFAD. 5XFAD mice demonstrated memory deficits at the age of 5 months. Thus, the water extract of Polygalae Radix (PR extract) was orally administered to 4-month-old 5XFAD mice that did not show signs of memory impairment. After consecutive administrations for 56 days, the PR extract prevented cognitive deficit and axon degeneration associated with the accumulation of amyloid beta (Abeta) plaques in the perirhinal cortex of the 5XFAD mice. PR extract did not influence the formation of Abeta plaques in the brain of the 5XFAD mice. In cultured neurons, the PR extract prevented axonal growth cone collapse and axonal atrophy induced by Abeta. Additionally, it prevented Abeta-induced endocytosis at the growth cone of cultured neurons. Our previous study reported that endocytosis inhibition was enough to prevent Abeta-induced growth cone collapse, axonal degeneration, and memory impairments. Therefore, the PR extract possibly prevented axonal degeneration and memory impairment by inhibiting endocytosis. PR is the first preventive drug candidate for AD that inhibits endocytosis in neurons. PMID- 29184494 TI - Aging Effect on Audiovisual Integrative Processing in Spatial Discrimination Task. AB - Multisensory integration is an essential process that people employ daily, from conversing in social gatherings to navigating the nearby environment. The aim of this study was to investigate the impact of aging on modulating multisensory integrative processes using event-related potential (ERP), and the validity of the study was improved by including "noise" in the contrast conditions. Older and younger participants were involved in perceiving visual and/or auditory stimuli that contained spatial information. The participants responded by indicating the spatial direction (far vs. near and left vs. right) conveyed in the stimuli using different wrist movements. electroencephalograms (EEGs) were captured in each task trial, along with the accuracy and reaction time of the participants' motor responses. Older participants showed a greater extent of behavioral improvements in the multisensory (as opposed to unisensory) condition compared to their younger counterparts. Older participants were found to have fronto-centrally distributed super-additive P2, which was not the case for the younger participants. The P2 amplitude difference between the multisensory condition and the sum of the unisensory conditions was found to correlate significantly with performance on spatial discrimination. The results indicated that the age-related effect modulated the integrative process in the perceptual and feedback stages, particularly the evaluation of auditory stimuli. Audiovisual (AV) integration may also serve a functional role during spatial-discrimination processes to compensate for the compromised attention function caused by aging. PMID- 29184496 TI - Andrographolide Protects against Aortic Banding-Induced Experimental Cardiac Hypertrophy by Inhibiting MAPKs Signaling. AB - Despite therapeutic advances, heart failure-related mortality rates remain high. Therefore, understanding the pathophysiological mechanisms involved in the remodeling process is crucial for the development of new therapeutic strategies. Andrographolide (Andr), a botanical compound, has potent cardio-protective effects due to its ability to inhibit mitogen-activated protein kinases (MAPKs). Andr has also been shown to inhibit inflammation and apoptosis, which are factors related to cardiac hypertrophy. Our aim was to evaluate the effects of Andr on cardiac hypertrophy and MAPKs activation. Thus, mice were subjected to aortic banding (AB) with/without Andr administration (25 mg/kg/day, orally). Cardiac function was accessed by echocardiography and hemodynamic parameters. Our results showed that Andr administration for 7 weeks decreased cardiac dysfunction and attenuated cardiac hypertrophy and fibrosis in AB mice. Andr treatment induced a strong reduction in the transcription of both hypertrophy (ANP, BNP, and beta MHC) and fibrosis related genes (collagen I, collagen III, CTGF, and TGFbeta). In addition, cardiomyocytes treated with Andr showed a reduced hypertrophic response to angiotensin II. Andr significantly inhibited MAPKs activation in both mouse hearts and cardiomyocytes. Treatment with a combination of MAPKs activators abolished the protective effects of Andr in cardiomyocytes. Furthermore, we found that Andr also inhibited the activation of cardiac fibroblasts via the MAPKs pathway, which was confirmed by the application of MAPKs inhibitors. In conclusion, Andr was found to confer a protective effect against experimental cardiac hypertrophy in mice, suggesting its potential as a novel therapeutic drug for pathological cardiac hypertrophy. PMID- 29184497 TI - Novel Two-Step Classifier for Torsades de Pointes Risk Stratification from Direct Features. AB - While pre-clinical Torsades de Pointes (TdP) risk classifiers had initially been based on drug-induced block of hERG potassium channels, it is now well established that improved risk prediction can be achieved by considering block of non-hERG ion channels. The current multi-channel TdP classifiers can be categorized into two classes. First, the classifiers that take as input the values of drug-induced block of ion channels (direct features). Second, the classifiers that are built on features extracted from output of the drug-induced multi-channel blockage simulations in the in-silico models (derived features). The classifiers built on derived features have thus far not consistently provided increased prediction accuracies, and hence casts doubt on the value of such approaches given the cost of including biophysical detail. Here, we propose a new two-step method for TdP risk classification, referred to as Multi-Channel Blockage at Early After Depolarization (MCB@EAD). In the first step, we classified the compound that produced insufficient hERG block as non torsadogenic. In the second step, the role of non-hERG channels to modulate TdP risk are considered by constructing classifiers based on direct or derived features at critical hERG block concentrations that generates EADs in the computational cardiac cell models. MCB@EAD provides comparable or superior TdP risk classification of the drugs from the direct features in tests against published methods. TdP risk for the drugs highly correlated to the propensity to generate EADs in the model. However, the derived features of the biophysical models did not improve the predictive capability for TdP risk assessment. PMID- 29184498 TI - Development of the Digital Arthritis Index, a Novel Metric to Measure Disease Parameters in a Rat Model of Rheumatoid Arthritis. AB - Despite a broad spectrum of anti-arthritic drugs currently on the market, there is a constant demand to develop improved therapeutic agents. Efficient compound screening and rapid evaluation of treatment efficacy in animal models of rheumatoid arthritis (RA) can accelerate the development of clinical candidates. Compound screening by evaluation of disease phenotypes in animal models facilitates preclinical research by enhancing understanding of human pathophysiology; however, there is still a continuous need to improve methods for evaluating disease. Current clinical assessment methods are challenged by the subjective nature of scoring-based methods, time-consuming longitudinal experiments, and the requirement for better functional readouts with relevance to human disease. To address these needs, we developed a low-touch, digital platform for phenotyping preclinical rodent models of disease. As a proof-of-concept, we utilized the rat collagen-induced arthritis (CIA) model of RA and developed the Digital Arthritis Index (DAI), an objective and automated behavioral metric that does not require human-animal interaction during the measurement and calculation of disease parameters. The DAI detected the development of arthritis similar to standard in vivo methods, including ankle joint measurements and arthritis scores, as well as demonstrated a positive correlation to ankle joint histopathology. The DAI also determined responses to multiple standard-of-care (SOC) treatments and nine repurposed compounds predicted by the SMarTRTM Engine to have varying degrees of impact on RA. The disease profiles generated by the DAI complemented those generated by standard methods. The DAI is a highly reproducible and automated approach that can be used in-conjunction with standard methods for detecting RA disease progression and conducting phenotypic drug screens. PMID- 29184499 TI - Aliskiren Improves Ischemia- and Oxygen Glucose Deprivation-Induced Cardiac Injury through Activation of Autophagy and AMP-Activated Protein Kinase. AB - Aliskiren is a direct renin inhibitor that has been effective in anti hypertension. We investigated whether aliskiren could improve the ischemia induced cardiac injury and whether the autophagy was involved in this effect. A myocardial infarction (MI) model was created by the ligation of the left anterior coronary artery in C57J/BL6 mice. They were treated for 1, 3, 7, and 14 days with vehicle or aliskiren (25 mg/kg/day via subcutaneous injection). In vivo, the MI mice exhibited worse cardiac function by echocardiographic assessment and showed larger myocardial scarring by light microscopy, whereas aliskiren treatment reversed these effects, which were also associated with the changes in caspase-3 and Bcl-2 expression as well as in the number of apoptotic cells. Aliskiren increased autophagy, as demonstrated by LC3B-II expression and transmission electron microscopy. Furthermore, H9c2 cardiomyocytes were employed as an in vitro model to examine the effects of aliskiren on apoptosis and autophagy under oxygen glucose deprivation (OGD)-induced injury. Aliskiren significantly increased cell viability in a dose-dependent manner. The beneficial effects of aliskiren were associated with decreased apoptosis and mitochondrial membrane potential as well as increased autophagy via increased autophagosome formation. We also found that aliskiren-induced cardiomyocyte survival occurred via AMP activated protein kinase (AMPK)-dependent autophagy. Taken together, these results indicated that aliskiren increased cardiomyocyte survival through increased autophagosomal formation and decreased apoptosis and necrosis via modulating AMPK expression. AMPK-dependent autophagy may represent a novel mechanism for aliskiren in ischemic cardiac disease therapy. PMID- 29184500 TI - CaMKII Requirement for in Vivo Insular Cortex LTP Maintenance and CTA Memory Persistence. AB - Calcium-calmodulin/dependent protein kinase II (CaMKII) plays an essential role in LTP induction, but since it has the capacity to remain persistently activated even after the decay of external stimuli it has been proposed that it can also be necessary for LTP maintenance and therefore for memory persistence. It has been shown that basolateral amygdaloid nucleus (Bla) stimulation induces long-term potentiation (LTP) in the insular cortex (IC), a neocortical region implicated in the acquisition and retention of conditioned taste aversion (CTA). Our previous studies have demonstrated that induction of LTP in the Bla-IC pathway before CTA training increased the retention of this task. Although it is known that IC-LTP induction and CTA consolidation share similar molecular mechanisms, little is known about the molecular actors that underlie their maintenance. The purpose of the present study was to evaluate the role of CaMKII in the maintenance of in vivo Bla-IC LTP as well as in the persistence of CTA long-term memory (LTM). Our results show that acute microinfusion of myr-CaMKIINtide, a selective inhibitor of CaMKII, in the IC of adult rats during the late-phase of in vivo Bla-IC LTP blocked its maintenance. Moreover, the intracortical inhibition of CaMKII 24 h after CTA acquisition impairs CTA-LTM persistence. Together these results indicate that CaMKII is a central key component for the maintenance of neocortical synaptic plasticity as well as for persistence of CTA-LTM. PMID- 29184501 TI - Identification of a New Potent Inhibitor Targeting KRAS in Non-small Cell Lung Cancer Cells. AB - KRAS (v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog) is an oncogenic driver with mutations in 30% of non-small cell lung cancer (NSCLC). However, there is no effective clinical drug even though it has been identified as an oncogene for 30 years. In this study, we identified a small molecule inhibitor compound 0375-0604 targeting KRAS by using molecular docking based virtual screening approach. Compound 0375-0604 had a good binding affinity to KRAS in vitro and exhibited cytotoxicity in oncogenic KRAS expressing NSCLC cell lines. Further mechanism study showed that compound 0375-0604 can block the formation of the complex of guanosine triphosphate (GTP) and KRAS in vitro. In addition, compound 0375-0604 inhibited KRAS downstream signaling pathway RAF/MEK/ERK and RAF/PI3K/AKT. Finally, we also found that this compound can inhibit the cell growth through G2/M cell cycle arrest and induce apoptosis on the NSCLC cell lines harboring KRAS mutation. Therefore, compound 0375-0604 may be considered as a potential KRAS inhibitor for treatment of NSCLC carrying KRAS oncogene.

AB - The histamine receptors (HRs) are traditional G protein-coupled receptors of extensive therapeutic interest. Recently, H3R and H4R subtypes have been targeted in drug discovery projects for inflammation, asthma, pain, cancer, Parkinson's, and Alzheimer's diseases, which includes searches for dual acting H3R/H4R ligands. In the present work, nine 1-[(2,3-dihydro-1-benzofuran-2 yl)methyl]piperazine (LINS01 series) molecules were synthesized and evaluated as H3R and H4R ligands. Our data show that the N-allyl-substituted compound LINS01004 bears the highest affinity for H3R (pKi 6.40), while the chlorinated compound LINS01007 has moderate affinity for H4R (pKi 6.06). In addition, BRET assays to assess the functional activity of Gi1 coupling indicate that all compounds have no intrinsic activity and act as antagonists of these receptors. Drug-likeness assessment indicated these molecules are promising leads for further improvements. In vivo evaluation of compounds LINS01005 and LINS01007 in a mouse model of asthma showed a better anti-inflammatory activity of LINS01007 (3 g/kg) than the previously tested compound LINS01005. This is the first report with functional data of these compounds in HRs, and our results also show the potential of their applications as anti-inflammatory. PMID- 29184505 TI - Heart Rate Fragmentation: A Symbolic Dynamical Approach. AB - Background: We recently introduced the concept of heart rate fragmentation along with a set of metrics for its quantification. The term was coined to refer to an increase in the percentage of changes in heart rate acceleration sign, a dynamical marker of a type of anomalous variability. The effort was motivated by the observation that fragmentation, which is consistent with the breakdown of the neuroautonomic-electrophysiologic control system of the sino-atrial node, could confound traditional short-term analysis of heart rate variability. Objective: The objectives of this study were to: (1) introduce a symbolic dynamical approach to the problem of quantifying heart rate fragmentation; (2) evaluate how the distribution of the different dynamical patterns ("words") varied with the participants' age in a group of healthy subjects and patients with coronary artery disease (CAD); and (3) quantify the differences in the fragmentation patterns between the two sample populations. Methods: The symbolic dynamical method employed here was based on a ternary map of the increment NN interval time series and on the analysis of the relative frequency of symbolic sequences (words) with a pre-defined set of features. We analyzed annotated, open-access Holter databases of healthy subjects and patients with CAD, provided by the University of Rochester Telemetric and Holter ECG Warehouse (THEW). Results: The degree of fragmentation was significantly higher in older individuals than in their younger counterparts. However, the fragmentation patterns were different in the two sample populations. In healthy subjects, older age was significantly associated with a higher percentage of transitions from acceleration/deceleration to zero acceleration and vice versa (termed "soft" inflection points). In patients with CAD, older age was also significantly associated with higher percentages of frank reversals in heart rate acceleration (transitions from acceleration to deceleration and vice versa, termed "hard" inflection points). Compared to healthy subjects, patients with CAD had significantly higher percentages of soft and hard inflection points, an increased percentage of words with a high degree of fragmentation and a decreased percentage of words with a lower degree of fragmentation. Conclusion: The symbolic dynamical method employed here was useful to probe the newly recognized property of heart rate fragmentation. The findings from these cross-sectional studies confirm that CAD and older age are associated with higher levels of heart rate fragmentation. Furthermore, fragmentation with healthy aging appears to be phenotypically different from fragmentation in the context of CAD. PMID- 29184504 TI - The Anti-allergic Cromones: Past, Present, and Future. AB - The anti-allergic cromones were originally synthesized in the 1960s by Fisons Plc, and the first drug to emerge from this program, disodium cromoglycate was subsequently marketed for the treatment of asthma and other allergic conditions. Whilst early studies demonstrated that the ability of the cromones to prevent allergic reactions was due to their 'mast cell stabilizing' properties, the exact pharmacological mechanism by which this occurred, remained a mystery. Here, we briefly review the history of these drugs, recount some aspects of their pharmacology, and discuss two new explanations for their unique actions. We further suggest how these findings could be used to predict further uses for the cromones. PMID- 29184506 TI - Recent Advances in the Cellular and Molecular Mechanisms of Hypothalamic Neuronal Glucose Detection. AB - The hypothalamus have been recognized for decades as one of the major brain centers for the control of energy homeostasis. This area contains specialized neurons able to detect changes in nutrients level. Among them, glucose-sensing neurons use glucose as a signaling molecule in addition to its fueling role. In this review we will describe the different sub-populations of glucose-sensing neurons present in the hypothalamus and highlight their nature in terms of neurotransmitter/neuropeptide expression. This review will particularly discuss whether pro-opiomelanocortin (POMC) neurons from the arcuate nucleus are directly glucose-sensing. In addition, recent observations in glucose-sensing suggest a subtle system with different mechanisms involved in the detection of changes in glucose level and their involvement in specific physiological functions. Several data point out the critical role of reactive oxygen species (ROS) and mitochondria dynamics in the detection of increased glucose. This review will also highlight that ATP-dependent potassium (KATP) channels are not the only channels mediating glucose-sensing and discuss the new role of transient receptor potential canonical channels (TRPC). We will discuss the recent advances in the determination of glucose-sensing machinery and propose potential line of research needed to further understand the regulation of brain glucose detection. PMID- 29184507 TI - Kir2.1-Nav1.5 Channel Complexes Are Differently Regulated than Kir2.1 and Nav1.5 Channels Alone. AB - Cardiac Kir2.1 and Nav1.5 channels generate the inward rectifier K+ (IK1) and the Na+ (INa) currents, respectively. There is a mutual interplay between the ventricular INa and IK1 densities, because Nav1.5 and Kir2.1 channels exhibit positive reciprocal modulation. Here we compared some of the biological properties of Nav1.5 and Kir2.1 channels when they are expressed together or separately to get further insights regarding their putative interaction. First we demonstrated by proximity ligation assays (PLAs) that in the membrane of ventricular myocytes Nav1.5 and Kir2.1 proteins are in close proximity to each other (<40 nm apart). Furthermore, intracellular dialysis with anti-Nav1.5 and anti-Kir2.1 antibodies suggested that these channels form complexes. Patch-clamp experiments in heterologous transfection systems demonstrated that the inhibition of the Ca2+/calmodulin-dependent protein kinase II (CaMKII) decreased the INa and the IK1 generated by Nav1.5 and Kir2.1 channels when they were coexpressed, but not the IK1 generated by Kir2.1 channels alone, suggesting that complexes, but not Kir2.1 channels, are a substrate of CaMKII. Furthermore, inhibition of CaMKII precluded the interaction between Nav1.5 and Kir2.1 channels. Inhibition of 14-3 3 proteins did not modify the INa and IK1 densities generated by each channel separately, whereas it decreased the INa and IK1 generated when they were coexpressed. However, inhibition of 14-3-3 proteins did not abolish the Nav1.5 Kir2.1 interaction. Inhibition of dynamin-dependent endocytosis reduced the internalization of Kir2.1 but not of Nav1.5 or Kir2.1-Nav1.5 complexes. Inhibition of cytoskeleton-dependent vesicular trafficking via the dynein/dynactin motor increased the IK1, but reduced the INa, thus suggesting that the dynein/dynactin motor is preferentially involved in the backward and forward traffic of Kir2.1 and Nav1.5, respectively. Conversely, the dynein/dynactin motor participated in the forward movement of Kir2.1-Nav1.5 complexes. Ubiquitination by Nedd4-2 ubiquitin-protein ligase promoted the Nav1.5 degradation by the proteasome, but not that of Kir2.1 channels. Importantly, the Kir2.1-Nav1.5 complexes were degraded following this route as demonstrated by the overexpression of Nedd4-2 and the inhibition of the proteasome with MG132. These results suggested that Kir2.1 and Nav1.5 channels closely interact with each other leading to the formation of a pool of complexed channels whose biology is similar to that of the Nav1.5 channels.

AB - The aim of this study was to compare the cardiometabolic demands of running on a curved non-motorized treadmill (cNMT) with overground (OVR) and motorized treadmill (MOT) running. Fourteen trained male (n = 7) and female (n = 7) runners ([Formula: see text] 56.6 +/- 4.0 mL.kg-1.min-1) participated in the study. Each experimental session consisted of 5 * 6-min bouts of running at progressively higher speeds, separated by 6-min rest (females 9-15 km.h-1; males 10.5-16.5 km.h 1). Oxygen consumption ([Formula: see text]) and heart rate (HR) during the last 2 min of each bout were measured using a portable metabolic cart. Running at a set speed on the cNMT required a higher percentage of [Formula: see text] than OVR (mean +/- 90% CI, 22 +/- 6%; ES +/- 90% CI, 1.87 +/- 0.15) and MOT (16 +/- 6%; ES 1.50 +/- 0.15) running. Similarly, HR during the cNMT was higher compared to OVR (25 +/- 9 beats.min-1, ES 1.23 +/- 0.14) and MOT (22 +/- 9 beats.min-1, ES 1.35 +/- 0.13) trials. The decline in running economy observed during the cNMT trial was negatively related to body mass (R2 0.493, P = 0.01), indicating lighter runners were required to work at a higher relative intensity to overcome treadmill belt resistance. These data demonstrate the higher cardiometabolic demand associated with running at a given speed on the cNMT. It is critical these differences are taken into account when prescribing training intensities on the cNMT or translating data from the laboratory to an athletic setting.

AB - Inhibition of poly(ADP-ribose) polymerase (PARP) may protect against coronary artery disease (CAD) in animal models, and rs1136410, a non-synonymous single nucleotide polymorphism (SNP) in PARP-1, has a potential impact on PARP activities in vitro. This two-stage case-control study, involving 2803 CAD patients and 2840 controls, aimed to investigate the associations of PARP-1 rs1136410 with CAD development, lipid levels, PARP activities, 8-hydroxy-2' dexyguanosine (8-OHdG), and interleukin (IL)-6 levels in a Chinese Han population. Assuming a recessive model, the variant genotype GG of SNP rs1136410 showed a significantly inverse association with CAD risk (adjusted odds ratio (OR) = 0.73, P < 0.001), left main coronary artery (LMCA) lesions (P = 0.003), vessel scores (P = 0.003), and modified Gensini scores (P < 0.001). There were significant correlations of SNP rs1136410 with higher levels of total cholesterol (TC) and lower levels of high-density lipoprotein cholesterol (HDL-c). In gene environment interaction analyses, participants with the variant genotype GG, but without smoking habit, type 2 diabetes mellitus, and hyperlipidemia, conferred an 84% (P < 0.001) decreased risk of CAD. The genotype-phenotype correlation analyses further supported the functional roles of SNP rs1136410 in decreasing PARP activities and 8-OHdG levels. Taken together, our data suggest that SNP rs1136410 may confer protection against CAD through modulation of PARP activities and gene-environment interactions in a Chinese Han population. PMID- 29184510 TI - Neuronal and Glial Clocks Underlying Structural Remodeling of Pacemaker Neurons in Drosophila. AB - A number of years ago we reported that ventral Lateral Neurons (LNvs), which are essential in the control of rest-activity cycles in Drosophila, undergo circadian remodeling of their axonal projections. This structural plasticity gives rise to changes in the degree of connectivity, which could provide a means of transmitting time of day information. Thus far, work from different laboratories has shown that circadian remodeling of adult projections relies on activity dependent and -independent mechanisms. In terms of clock- dependent mechanisms, several neuronal types undergoing circadian remodeling hinted to a differential effect of clock genes; while per mutants exhibited poorly developed axonal terminals giving rise to low complexity arbors, tim mutants displayed a characteristic hyper branching phenotype, suggesting these genes could be playing additional roles to those ascribed to core clock function. To shed light onto this possibility we altered clock gene levels through RNAi- mediated downregulation and expression of a dominant negative form exclusively in the adult LNvs. These experiments confirmed that the LNv clock is necessary to drive the remodeling process. We next explored the contribution of glia to the structural plasticity of the small LNvs through acute disruption of their internal clock. Interestingly, impaired glial clocks also abolished circadian structural remodeling, without affecting other clock-controlled outputs. Taken together our data shows that both neuronal and glial clocks are recruited to define the architecture of the LNv projections along the day, thus enabling a precise reconfiguration of the circadian network. PMID- 29184511 TI - Dose-Response Relationship of Neuromuscular Training for Injury Prevention in Youth Athletes: A Meta-Analysis. AB - Background: Youth athletes with intensive sports participation are at an increased risk of sustaining injuries. Neuromuscular training programs reduce sports-related injury risk in this population, however, the dose-response relationship is largely unknown. Thus, the aim of this meta-analysis was to identify the optimal frequency, volume, duration, and period of neuromuscular training to prevent injuries in youth athletes. Methods: Computerized database searches (PubMed, Scopus, SPORTDiscus, The Cochrane Library, PEDro) were conducted in January 2017, with search terms related to youth sports, neuromuscular training, and injury prevention. Eligible trials (i) evaluated a neuromuscular training program; (ii) included youth athletes of 21 years or younger; (iii) had an analytical design (RCTs, quasi-experimental, cohort studies); (iv) contained original data; (v) and provided injury data. Two reviewers independently extracted data and assessed quality of eligible studies. Injury rate ratios (IRRs) for lower extremity injuries were pooled meta analytically, and moderator analyses examined the effect of training frequency, duration, volume, and period. Results: Data from 16 trials yielded an overall risk reduction of 42% with neuromuscular training (IRR = 0.58, 95%CI 0.47-0.72). Training frequencies of two (IRR = 0.50; 95%CI 0.29-0.86) or three times (IRR = 0.40; 95%CI 0.31-0.53) per week revealed the largest risk reduction, and a weekly training volume of more than 30 min tended to be more effective compared to lower volumes. Programs with 10-15 min (IRR = 0.55; 95%CI 0.42-0.72) session duration produced effects comparable to those with longer session duration (IRR = 0.60; 95%CI 0.46-0.76). Interventions lasting more than 6 months were not superior to shorter programs. Conclusion: This meta-analysis revealed that NMT performed in short bouts of 10-15 min, two to three times per week, with a weekly training volume of 30-60 min had the largest preventive effect for lower extremity injuries in youth athletes. These effects can be achieved within 20-60 sessions and training periods of <6 months. The present results are derived from a relatively small number of studies with heterogeneous methodological quality and should be treated with caution. The study was a priori registered at PROSPERO (CRD42016053473). PMID- 29184513 TI - Hoxa2 Inhibits Bone Morphogenetic Protein Signaling during Osteogenic Differentiation of the Palatal Mesenchyme. AB - Cleft palate is one of the most common congenital birth defects worldwide. The homeobox (Hox) family of genes are key regulators of embryogenesis, with Hoxa2 having a direct role in secondary palate development. Hoxa2-/- mice exhibit cleft palate; however, the cellular and molecular mechanisms leading to cleft palate in Hoxa2-/- mice is largely unknown. Addressing this issue, we found that Hoxa2 regulates spatial and temporal programs of osteogenic differentiation in the developing palate by inhibiting bone morphogenetic protein (BMP) signaling dependent osteoblast markers. Expression of osteoblast markers, including Runx2, Sp7, and AlpI were increased in Hoxa2-/- palatal shelves at embryonic day (E) 13.5 and E15.5. Hoxa2-/- mouse embryonic palatal mesenchyme (MEPM) cells exhibited increased bone matrix deposition and mineralization in vitro. Moreover, loss of Hoxa2 resulted in increased osteoprogenitor cell proliferation and osteogenic commitment during early stages of palate development at E13.5. Consistent with upregulation of osteoblast markers, Hoxa2-/- palatal shelves displayed higher expression of canonical BMP signaling in vivo. Blocking BMP signaling in Hoxa2-/- primary MEPM cells using dorsomorphin restored cell proliferation and osteogenic differentiation to wild-type levels. Collectively, these data demonstrate for the first time that Hoxa2 may regulate palate development by inhibiting osteogenic differentiation of palatal mesenchyme via modulating BMP signaling. PMID- 29184512 TI - Strategies Developed to Induce, Direct, and Potentiate Bone Healing. AB - Bone exhibits a great ability for endogenous self-healing. Nevertheless, impaired bone regeneration and healing is on the rise due to population aging, increasing incidence of bone trauma and the clinical need for the development of alternative options to autologous bone grafts. Current strategies, including several biomolecules, cellular therapies, biomaterials, and different permutations of these, are now developed to facilitate the vascularization and the engraftment of the constructs, to recreate ultimately a bone tissue with the same properties and characteristics of the native bone. In this review, we browse the existing strategies that are currently developed, using biomolecules, cells and biomaterials, to induce, direct and potentiate bone healing after injury and further discuss the biological processes associated with this repair.

Our case reports on the topology-related effect of lesions on different brain networks involved in the phenomenology of the patient's psychotic symptoms. PMID- 29184515 TI - The Influence of Empathy and Morality of Violent Video Game Characters on Gamers' Aggression. AB - According to the General Aggression Model, situational factors (such as the game characters) and personal factors both affect a gamer's acquisition of aggressive behavior. Previous studies have found not only that the surface features of game characters, such as appearance and clothing, but also that their inherent characteristics, such as morality and identity, can influence a gamer's attitude and behavior. Research has also shown that empathy, as a personal factor, can protect gamers from the impact of media violence. However, past research has focused primarily on single factors affecting the player rather than more comprehensive investigations. This study investigates the influence of the game character's moral features and levels of empathy on the gamer's aggression. The participants were 120 Chinese university students (61 females and 59 males) with ages ranging from 17 to 27 years. Participants first completed a series of questionnaires: a user experience questionnaire, a video game questionnaire, the Buss-Perry Aggression Questionnaire, and a modified version of the Interpersonal Reactivity Index. All participants then had 5 min of practice playing a violent video game. They were then divided into three groups: a high empathy group, a low empathy group, and a no empathy group. After the practice, participants in the high and low empathy groups read empathy materials relating to the game characters; participants in the no empathy group began formal gameplay. All participants played the game for 20 min. Finally, participants were required to complete the Scale of Hostility Status questionnaire, the Implicit Aggression Test, and the Competitive Reaction Time Test. The results show that empathy and the morality of game characters both influence aggression, but empathy affected aggression differently in the participants playing justified roles (i.e., killing others for a moral reason in the game) compared to those playing unjustified roles (i.e., killing others for immoral reasons in the game). In the high empathy condition, the implicit aggression of justified players was significantly higher than those playing unjustified roles. However, high empathy does not always play a protective role, and its effect is restricted by the features of the game characters. PMID- 29184516 TI - Chasing the Rainbow: The Non-conscious Nature of Being. AB - Despite the compelling subjective experience of executive self-control, we argue that "consciousness" contains no top-down control processes and that "consciousness" involves no executive, causal, or controlling relationship with any of the familiar psychological processes conventionally attributed to it. In our view, psychological processing and psychological products are not under the control of consciousness. In particular, we argue that all "contents of consciousness" are generated by and within non-conscious brain systems in the form of a continuous self-referential personal narrative that is not directed or influenced in any way by the "experience of consciousness." This continuously updated personal narrative arises from selective "internal broadcasting" of outputs from non-conscious executive systems that have access to all forms of cognitive processing, sensory information, and motor control. The personal narrative provides information for storage in autobiographical memory and is underpinned by constructs of self and agency, also created in non-conscious systems. The experience of consciousness is a passive accompaniment to the non conscious processes of internal broadcasting and the creation of the personal narrative. In this sense, personal awareness is analogous to the rainbow which accompanies physical processes in the atmosphere but exerts no influence over them. Though it is an end-product created by non-conscious executive systems, the personal narrative serves the powerful evolutionary function of enabling individuals to communicate (externally broadcast) the contents of internal broadcasting. This in turn allows recipients to generate potentially adaptive strategies, such as predicting the behavior of others and underlies the development of social and cultural structures, that promote species survival. Consequently, it is the capacity to communicate to others the contents of the personal narrative that confers an evolutionary advantage-not the experience of consciousness (personal awareness) itself. PMID- 29184517 TI - Positive Healthy Organizations: Promoting Well-Being, Meaningfulness, and Sustainability in Organizations. AB - This contribution deals with the concept of healthy organizations and starts with a definition of healthy organizations and healthy business. In healthy organizations, culture, climate, and practices create an environment conducive to employee health and safety as well as organizational effectiveness (Lowe, 2010). A healthy organization thus leads to a healthy and successful business (De Smet et al., 2007; Grawitch and Ballard, 2016), underlining the strong link between organizational profitability and workers' well-being. Starting from a positive perspective focused on success and excellence, the contribution describes how positive organizational health psychology evolved from occupational health psychology to positive occupational health psychology stressing the importance of a primary preventive approach. The focus is not on deficiency and failure but on a positive organizational attitude that proposes interventions at different levels: individual, group, organization, and inter-organization. Healthy organizations need to find the right balance between their particular situation, sector, and culture, highlighting the importance of well-being and sustainability. This contribution discusses also the sustainability of work-life projects and the meaning of work in healthy organizations, stressing the importance of recognizing, respecting, and using the meaning of work as a key for growth and success. Finally, the contribution discusses new research and intervention opportunities for healthy organizations. PMID- 29184519 TI - Folk-Psychological Interpretation of Human vs. Humanoid Robot Behavior: Exploring the Intentional Stance toward Robots. AB - People rely on shared folk-psychological theories when judging behavior. These theories guide people's social interactions and therefore need to be taken into consideration in the design of robots and other autonomous systems expected to interact socially with people. It is, however, not yet clear to what degree the mechanisms that underlie people's judgments of robot behavior overlap or differ from the case of human or animal behavior. To explore this issue, participants (N = 90) were exposed to images and verbal descriptions of eight different behaviors exhibited either by a person or a humanoid robot. Participants were asked to rate the intentionality, controllability and desirability of the behaviors, and to judge the plausibility of seven different types of explanations derived from a recently proposed psychological model of lay causal explanation of human behavior. Results indicate: substantially similar judgments of human and robot behavior, both in terms of (1a) ascriptions of intentionality/controllability/desirability and in terms of (1b) plausibility judgments of behavior explanations; (2a) high level of agreement in judgments of robot behavior - (2b) slightly lower but still largely similar to agreement over human behaviors; (3) systematic differences in judgments concerning the plausibility of goals and dispositions as explanations of human vs. humanoid behavior. Taken together, these results suggest that people's intentional stance toward the robot was in this case very similar to their stance toward the human. PMID- 29184518 TI - Proposal Allocation Ratio as a Moderator of Interpersonal Responsibility Effects on Hostile Decision-Making in the Ultimatum Game. AB - Interpersonal responsibility is an indigenous Chinese personality construct, which is regarded to have positive social functions. Two studies were designed to explore the relationship among interpersonal responsibility, proposal allocation ratio, and responders' hostile decisions in an ultimatum game. Study 1 was a scenario study using a hypothetical ultimatum game with a valid sample of 551 high school students. Study 2 was an experimental study which recruited 54 undergraduate students to play the incentivized ultimatum game online. The results of the two studies showed a significantly negative correlation between interpersonal responsibility and responders' rejection responses only when the proposal allocation ratio was 3:7. In addition, in Study 2, interpersonal responsibility had negative effects on responders' rejection responses under the offer of 3:7, even after controlling for the Big Five personality traits. Taken together, proposal allocation ratio might moderate the effects of interpersonal responsibility on hostile decision-making in the ultimatum game. The social function of interpersonal responsibility might be beyond the Big Five. PMID- 29184520 TI - Proposed Diagnostic Criteria for Misophonia: A Multisensory Conditioned Aversive Reflex Disorder.

PMID- 29184523 TI - Eysenck's Theory of Personality and the Role of Background Music in Cognitive Task Performance: A Mini-Review of Conflicting Findings and a New Perspective. AB - The question of whether background music is able to enhance cognitive task performance is of interest to scholars, educators, and stakeholders in business alike. Studies have shown that background music can have beneficial, detrimental or no effects on cognitive task performance. Extraversion-and its postulated underlying cause, cortical arousal-is regarded as an important factor influencing the outcome of such studies. According to Eysenck's theory of personality, extraverts' cortical arousal at rest is lower compared to that of introverts. Scholars have thus hypothesized that extraverts should benefit from background music in cognitive tasks, whereas introverts' performance should decline with music in the background. Reviewing studies that have considered extraversion as a mediator of the effect of background music on cognitive task performance, it is demonstrated that there is as much evidence in favor as there is against Eysenck's theory of personality. Further, revisiting Eysenck's concept of cortical arousal-which has traditionally been assessed by activity in the EEG alpha band-and reviewing literature on the link between extraversion and cortical arousal, it is revealed that there is conflicting evidence. Due to Eysenck's focus on alpha power, scholars have largely neglected higher frequency bands in the EEG signal as indicators of cortical arousal. Based on recent findings, it is suggested that beta power might not only be an indicator of alertness and attention but also a predictor of cognitive task performance. In conclusion, it is proposed that focused music listening prior to cognitive tasks might be a more efficient way to boost performance than listening to background music during cognitive tasks. PMID- 29184522 TI - Reconstructing Tone Sequences from Functional Magnetic Resonance Imaging Blood Oxygen Level Dependent Responses within Human Primary Auditory Cortex. AB - Here we show that, using functional magnetic resonance imaging (fMRI) blood oxygen level dependent (BOLD) responses in human primary auditory cortex, it is possible to reconstruct the sequence of tones that a person has been listening to over time. First, we characterized the tonotopic organization of each subject's auditory cortex by measuring auditory responses to randomized pure tone stimuli and modeling the frequency tuning of each fMRI voxel as a Gaussian in log frequency space. Then, we tested our model by examining its ability to work in reverse. Auditory responses were re-collected in the same subjects, except this time they listened to sequences of frequencies taken from simple songs (e.g., "Somewhere Over the Rainbow"). By finding the frequency that minimized the difference between the model's prediction of BOLD responses and actual BOLD responses, we were able to reconstruct tone sequences, with mean frequency estimation errors of half an octave or less, and little evidence of systematic biases. PMID- 29184524 TI - A Qualitative Approach on Motives and Aspects of Risks in Freeriding. AB - Recent research has shown that there are multiple motives for participation in high-risk sport; however these results have come from studies that consider a number of different sports. Therefore, the aim of the present study was to better understand the motives and risk-related aspects of freeriding, using a qualitative approach. Semi-structured interviews were conducted with 40 professional and semi-professional freeride skiers and snowboarders. All freeriders were highly experienced, of different age (19-44 years; 27.5 +/- 4.5 years), gender (female = 13), and profession (professional athletes = 11). Analyses were done using MAXQDA software following a code theme approach. Mixed methods analyses using chi2-tests were computed for age (<25 years >=) and gender (female/male) on motives and risk factors. Five emerging themes were found, namely Challenge (n = 36), Friends (n = 31), Nature (n = 27), Balance (n = 26), and Freedom (n = 26). A sixth theme Habit (n = 13) was allocated as a subtheme due to minor responses. With regard to risk management, participants decided upon a risk calculation strategy which included multiple factors (e.g., planning, conditions, current situation, knowledge, and experience). Trusting in one's own abilities, avoiding negative fear and having trusted partners were among the risk factors. Deliberately seeking out dangerous situations was not a motive. chi2 tests revealed no gender or age differences regarding aspects of risk (range of p scores: p = 0.17-1.00) or motives (p = 0.16-1.00). Freeriding was shown to provide positive effects through participation. Some important factors seem to be motivational drivers for freeriders: challenging oneself, experiencing nature, contributing to deep friendships, freeriding as a counterbalance to everyday life and escape from restrictions. Contrary to prior research reports on sensation seeking, experienced freeriders do not search the risk; they seem to minimize it based on knowledge and experience. Analyses of the present data did not show any gender or age differences, which may suggest that experience plays a more important role in high-risk sports than age or gender. Future research should qualitatively investigate further terrain based activities and implement motives and risk-related factors in quantitative research. PMID- 29184525 TI - Decomposing a Chunk into Its Elements and Reorganizing Them As a New Chunk: The Two Different Sub-processes Underlying Insightful Chunk Decomposition. AB - Familiar chunks can be processed highly efficiently, and this automatic process can prohibit the problem solver from developing novel and original ways to creatively solve difficult problems. For this reason, the role of the reverse process, chunk decomposition (CD), the process by which familiar patterns are broken down into their component elements in order to be regrouped in another meaningful manner, has been generally recognized as part of the creative process. However, previous studies on this issue have mainly focused on the decomposition process of CD (the D-process), while the reorganization process of CD has been greatly neglected or has not been distinctively identified in previous work. In this paper, we argue that the R-process could be equally as important as the D process for CD. Even if a problem solver manages to decompose a familiar chunk into its elements, he or she still may not solve the problem if these elements are not successfully organized in a new and meaningful manner. To investigate whether the cognitive mechanism of the R-process is different from that of the D process, we designed an experiment for detecting the effects of chunk tightness, which is regarded as the key factor in CD and which can be experimentally manipulated by the radical-level (loose) and stroke-level (tight) Chinese character CD tasks in the D-process, the R-process, and the more purified organization task (the O-process task) that does not involve the decomposition process. Our results showed that the stroke-level (tight) task was more difficult than the radical-level (loose) task for the D-process. However, for the R process, the stroke- and radical-level tasks showed no differences in performance. Moreover, for the more purified reorganization task, the O-process task, the radical-level organization and reorganization could be even more difficult than the stroke-level organization and reorganization. This result demonstrated that the cognitive processes underlying chunk decomposition and reorganization are fundamentally different. Therefore, more general concepts such as chunk restructuring that could include both D- and R-processes might be more suitable in accounting for this type of creative insight. PMID- 29184527 TI - Severity of Autism Symptoms and Degree of Attentional Difficulties Predicts Emotional and Behavioral Problems in Children with High-Functioning Autism; a Two Year Follow-up Study. AB - Children with autism often struggle with emotional and behavioral problems (EBP). This study investigated whether level of autism symptoms, attention problems or verbal IQ at baseline can predict EBP 2 years later in children with High Functioning Autism (HFA). Thirty-four participants with HFA and 45 typically developing children (TD) (ages 9-16) were assessed with parent ratings of EBP, autism symptoms, attention problems, and a test of verbal IQ. The amount of autism symptoms and degree of attention problems at baseline significantly predicted EBP at follow-up, whereas verbal IQ did not. The findings from this study emphasize the importance of assessing and understanding the consequences of autism symptoms and attention problems when treating EBP in children with HFA. Furthermore, interventions aimed at improving ASD symptoms may positively affect the prevalence of EBP in children with HFA. PMID- 29184526 TI - Loneliness, Resilience, Mental Health, and Quality of Life in Old Age: A Structural Equation Model. AB - Objectives: In the scientific literature on aging, a recent core issue has been the role of individuals' internal and external resources, which are considered intrinsically connected, in contributing synergistically to physical and psychological quality of life (QoL). The current study investigates the way in which psychological factors-such as, loneliness, resilience, and mental states, in terms of depression and anxiety symptoms-affect the perceived QoL among elderly individuals. Method: Data from 290 elderly Italian participants were used to study the mediation effects of both mental health and resilience to elucidate the relationship between loneliness and psychophysical QoL. Results: The best model we obtained supports the mediation effect of both resilience and mental health between loneliness and mental and physical QoL. These results highlight that loneliness influences mental and physical QoL via two pathways, with the impact of loneliness mediated by mental health and resilience dimensions. Conclusions: The findings suggest the importance of the support that elderly people receive from social relationships. In terms of clinical interventions, the reduction of loneliness could be an important factor in primary prevention or the recovery process. A way to reduce levels of mental distress could be represented by the increasing of resilience and self-efficacy and reduction of loneliness dissatisfaction. A high degree of resiliency contributes to increasing perceived life quality at the physical and psychological levels, and at the same time, reducing anxiety and depressive symptoms. PMID- 29184528 TI - Psychometric Properties of the German Version of the Health Regulatory Focus Scale. AB - The Health Regulatory Focus Scale (HRFS) is a short scale which measures an individual's prevention and promotion focus in a health-specific context. The main objective of this study was to examine the psychometric properties of the newly translated German version of the HRFS. Reliability and item characteristics were found to be satisfactory. Validity of both subscales toward other psychological constructs including behavioral approach and avoidance, core self evaluations, optimism, pessimism, neuroticism, as well as several measures of physical and mental health was shown. In addition, invariance of the measure across age and gender groups was shown. Exploratory as well as confirmatory factor analyses clearly indicated a two-factorial structure with a moderate correlation between the two latent constructs. Differences in health promotion and prevention focus between socio-demographic groups are discussed. The HRFS is found to be a valid and reliable instrument for the assessment of regulatory focus in health-related environments. PMID- 29184529 TI - The Changing Role of Health Care Professionals in Nursing Homes: A Systematic Literature Review of a Decade of Change. AB - Although the role of health care professionals is known to have changed over the last years, few formal efforts have been made to examine this change through means of a scientific review. Therefore, the goal of this paper was to investigate the changing role of health care professionals in nursing homes, as well as the conditions that make this change possible. A systematic review of health care literature published in the last decade (2007-2017) was utilized to address these goals. Our findings suggest that although health care in nursing homes is shifting from task-oriented care to relation-oriented care (e.g., through an increased focus on patient dignity), various obstacles (e.g., negative self-image, work pressure, and a lack of developmental opportunities), needs (e.g., shared values, personal development, personal empowerment, team development, and demonstrating expertise), and competences (e.g., communication skills, attentiveness, negotiation skills, flexibility, teamwork, expertise, and coaching and leadership skills) still need to be addressed in order to successfully facilitate this change. As such, this paper provides various implications for health care research, health care institutions, practitioners, HR professionals and managers, and occupational health research. PMID- 29184530 TI - The Video Head Impulse Test to Assess the Efficacy of Vestibular Implants in Humans. AB - The purpose of this study was to evaluate whether it is possible to restore the high-frequency angular vestibulo-ocular reflex (aVOR) in patients suffering from a severe bilateral vestibulopathy (BV) and implanted with a vestibular implant prototype. Three patients (S1-3) participated in the study. They received a prototype vestibular implant with one to three electrode branches implanted in the proximity of the ampullary branches of the vestibular nerve. Five electrodes were available for electrical stimulation: one implanted in proximity of the left posterior ampullary nerve in S1, one in the left lateral and another one in the superior ampullary nerves in S2, and one in the right lateral and another one in the superior ampullary nerves in S3. The high-frequency aVOR was assessed using the video head impulse test (EyeSeeCam; EyeSeeTec, Munich, Germany), while motion modulated electrical stimulation was delivered via one of the implanted vestibular electrodes at a time. aVOR gains were compared to control measurements obtained in the same patients when the device was not activated. In three out of the five tested electrodes the aVOR gain increased monotonically with increased stimulation strength when head impulses were delivered in the plane of the implanted canal. In these cases, gains ranging from 0.4 to values above 1 were measured. A "reversed" aVOR could also be generated when inversed stimulation paradigms were used. In most cases, the gain for excitatory head impulses was superior to that recorded for inhibitory head impulses, consistent with unilateral vestibular stimulation. Improvements of aVOR gain were generally accompanied by a concomitant decrease of corrective saccades, providing additional evidence of an effective aVOR. High inter-electrode and inter-subject variability were observed. These results, together with previous research, demonstrate that it is possible to restore the aVOR in a broad frequency range using motion-modulated electrical stimulation of the vestibular afferents. This provides additional encouraging evidence of the possibility of achieving a useful rehabilitation alternative for patients with BV in the near future. PMID- 29184531 TI - Stent-Assisted Coiling of Ruptured and Incidental Aneurysms of the Intracranial Circulation Using Moderately Flow-Redirecting, Braided Leo Stents-Initial Experience in 39 Patients. AB - Background: Flow diversion (FD)-a young technique using stents with highly increased surface coverage-was introduced to treat complex aneurysms without intra-aneurysmal material placement and has amended the spectrum of endovascular techniques such as stent-assisted coil occlusion considerably. However, ischemic complications, a common side effect in FD, occur more frequently compared with the conventional endovascular approaches and certainly limit the indication of this technique. Our study aimed to investigate the feasibility and efficacy of stent-assisted coiling using low profile self-expandable stents, which exhibit only moderate flow-redirecting properties and therefore represent a combination of hemodynamic endovascular and occlusive endosaccular therapy. Materials and methods: 39 Patients were included in our retrospective study. Occlusion rates were assessed 6 months after the procedure in a total of 27 cases using the Raymond scale. Results: Complete occlusion (Raymond I) was achieved in 24/27 aneurysms. Small neck remnants (Raymond II) were evident in 3/27 aneurysms. There were no cases with sac remnant or complete persistence of aneurysmal filling (Raymond III and IV). Conclusion: Our study demonstrates interventional treatment of intracranial aneurysms using flow-redirecting stent-assisted coiling to be technically feasible and highly effective in aneurysmal occlusion. We believe that this approach is outstanding in the prevention of long-term aneurysmal reperfusion and exhibits a more acceptable risk profile than highly efficient FD techniques. PMID- 29184532 TI - Early New Ischemic Lesions Located Outside the Initially Affected Vascular Territory Appear More Often in Stroke Patients with Elevated Glycated Hemoglobin (HbA1c). AB - Background: Early new ischemic lesions are common in patients with an acute ischemic stroke. These new ischemic lesions may represent the natural course of the initial stroke or de novo events. Objective: We hypothesized that early new ischemic lesions located outside the initially affected vascular territory would point at de novo events. Therefore, we differentiated new ischemic lesions located outside the initially affected vascular territory from those occurring only inside the initially affected vascular territory to identify risk factors that are associated with de novo events. Methods: Stroke patients underwent three magnetic resonance imaging examinations (at 3-T): on admission, on the next day and 4-7 days after symptom onset (clinicaltrials.gov: NCT00715533). Diffusion weighted imaging (DWI) lesions were delineated, coregistered, and then analyzed for new hyperintensities on follow-up examinations by raters blinded to clinical details. Patients were classified as having "new distant lesions" if new DWI lesions appeared outside or both outside and inside the initially affected vascular territory or "new local lesions" if they were only inside. Results: 115 patients with early new DWI lesions constitute the study population. Sixteen patients (14%) had new distant lesions and 99 patients (86%) had new local lesions. In comparison between patients with new distant and new local lesions, patients with new distant lesions had significantly more often elevated glycated hemoglobin (HbA1c >= 6.5%; p = 0.022). Conclusion: Our data indicate that patients with elevated HbA1c have an increased risk for new, de novo ischemic lesions in the acute phase after an ischemic stroke. PMID- 29184533 TI - Correlations between Motor Symptoms across Different Motor Tasks, Quantified via Random Forest Feature Classification in Parkinson's Disease. AB - Background: Objective assessments of Parkinson's disease (PD) patients' motor state using motion capture techniques are still rarely used in clinical practice, even though they may improve clinical management. One major obstacle relates to the large dimensionality of motor abnormalities in PD. We aimed to extract global motor performance measures covering different everyday motor tasks, as a function of a clinical intervention, i.e., deep brain stimulation (DBS) of the subthalamic nucleus. Methods: We followed a data-driven, machine-learning approach and propose performance measures that employ Random Forests with probability distributions. We applied this method to 14 PD patients with DBS switched-off or on, and 26 healthy control subjects performing the Timed Up and Go Test (TUG), the Functional Reach Test (FRT), a hand coordination task, walking 10-m straight, and a 90 degrees curve. Results: For each motor task, a Random Forest identified a specific set of metrics that optimally separated PD off DBS from healthy subjects. We noted the highest accuracy (94.6%) for standing up. This corresponded to a sensitivity of 91.5% to detect a PD patient off DBS, and a specificity of 97.2% representing the rate of correctly identified healthy subjects. We then calculated performance measures based on these sets of metrics and applied those results to characterize symptom severity in different motor tasks. Task-specific symptom severity measures correlated significantly with each other and with the Unified Parkinson's Disease Rating Scale (UPDRS, part III, correlation of r2 = 0.79). Agreement rates between different measures ranged from 79.8 to 89.3%. Conclusion: The close correlation of PD patients' various motor abnormalities quantified by different, task-specific severity measures suggests that these abnormalities are only facets of the underlying one-dimensional severity of motor deficits. The identification and characterization of this underlying motor deficit may help to optimize therapeutic interventions, e.g., to "automatically" adapt DBS settings in PD patients. PMID- 29184534 TI - Pronounced Structural and Functional Damage in Early Adult Pediatric-Onset Multiple Sclerosis with No or Minimal Clinical Disability. AB - Pediatric-onset multiple sclerosis (POMS) may represent a model of vulnerability to damage occurring during a period of active maturation of the human brain. Whereas adaptive mechanisms seem to take place in the POMS brain in the short medium term, natural history studies have shown that these patients reach irreversible disability, despite slower progression, at a significantly younger age than adult-onset MS (AOMS) patients. We tested for the first time whether significant brain alterations already occurred in POMS patients in their early adulthood and with no or minimal disability (n = 15) in comparison with age- and disability-matched AOMS patients (n = 14) and to normal controls (NC, n = 20). We used a multimodal MRI approach by modeling, using FSL, voxelwise measures of microstructural integrity of white matter tracts and gray matter volumes with those of intra- and internetwork functional connectivity (FC) (analysis of variance, p <= 0.01, corrected for multiple comparisons across space). POMS patients showed, when compared with both NC and AOMS patients, altered measures of diffusion tensor imaging (reduced fractional anisotropy and/or increased diffusivities) and higher probability of lesion occurrence in a clinically eloquent region for physical disability such as the posterior corona radiata. In addition, POMS patients showed, compared with the other two groups, reduced long range FC, assessed from resting functional MRI, between default mode network and secondary visual network, whose interaction subserves important cognitive functions such as spatial attention and visual learning. Overall, this pattern of structural damage and brain connectivity disruption in early adult POMS patients with no or minimal clinical disability might explain their unfavorable clinical outcome in the long term. PMID- 29184535 TI - Sex Differences in the Regulation of Offensive Aggression and Dominance by Arginine-Vasopressin. AB - Arginine-vasopressin (AVP) plays a critical role in the regulation of offensive aggression and social status in mammals. AVP is found in an extensive neural network in the brain. Here, we discuss the role of AVP in the regulation of aggression in the limbic system with an emphasis on the critical role of hypothalamic AVP in the control of aggression. In males, activation of AVP V1a receptors (V1aRs) in the hypothalamus stimulates offensive aggression, while in females activation of V1aRs inhibits aggression. Serotonin (5-HT) also acts within the hypothalamus to modulate the effects of AVP on aggression in a sex dependent manner. Activation of 5-HT1a receptors (5-HT1aRs) inhibits aggression in males and stimulates aggression in females. There are also striking sex differences in the mechanisms underlying the acquisition of dominance. In males, the acquisition of dominance is associated with the activation of AVP-containing neurons in the hypothalamus. By contrast, in females, the acquisition of dominance is associated with the activation of 5-HT-containing neurons in the dorsal raphe. AVP and 5-HT also play critical roles in the regulation of a form of social communication that is important for the maintenance of dominance relationships. In both male and female hamsters, AVP acts via V1aRs in the hypothalamus, as well as in other limbic structures, to communicate social status through the stimulation of a form of scent marking called flank marking. 5-HT acts on 5-HT1aRs as well as other 5-HT receptors within the hypothalamus to inhibit flank marking induced by AVP in both males and females. Interestingly, while AVP and 5-HT influence the expression of aggression in opposite ways in males and females, there are no sex differences in the effects of AVP and 5-HT on the expression of social communication. Given the profound sex differences in the incidence of many psychiatric disorders and the increasing evidence for a relationship between aggressiveness/dominance and the susceptibility to these disorders, understanding the neural regulation of aggression and social status will have significant import for translational studies. PMID- 29184537 TI - Probiotics Ingestion Does Not Directly Affect Thyroid Hormonal Parameters in Hypothyroid Patients on Levothyroxine Treatment. AB - Purpose: The relationship between probiotics and levothyroxine (LT4) requirement has not yet been investigated. The aim of this study was to assess whether a mixture of highly charged Lactobacilli and Bifidobacteria (VSL#3(r)) is able to influence LT4 metabolism acting on the gut microbiota. Methods: A prospective, randomized, single-blind, controlled, investigator-started clinical trial was carried out. Patients with primary hypothyroidism were randomly assigned to the study (VSL#3(r) + LT4) and the control group (LT4). A 2-month treatment phase was followed by 2 months of follow-up. Clinical examination, blood tests for thyroid function and for peripheral tissue markers of thyroid hormones (PTM) were performed monthly. LT4 dose adjustments were performed when necessary. Results: Thirty-nine patients were enrolled in the study group and 41 in the control group. No difference in thyroid function [thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), and free thyroxine (fT4)] and PTM was found between groups and among visits. FT3/fT4 ratio was directly correlated to TSH at each visit in both groups, with the exception of the first evaluation of probiotics treated subjects (rho = 0.287, p = 0.076). LT4 daily dose adjustments occurred more frequently in the control than in the study group (p = 0.007), despite no differences in the mean LT4 daily dose. In particular, LT4 doses were increased six times in the control group and decreased four times in the study group. Conclusion: VSL#3(r) does not directly alter thyroid functional compensation. A probiotics-mediated influence on thyroid hormones homeostasis is suggested since probiotics supplementation could be able to prevent serum hormonal fluctuations.

AB - Context: Myotonic dystrophies (DM) are dominantly inherited muscle disorders characterized by myotonia, muscle weakness, and wasting. The reasons for sarcopenia in DMs are uncleared and multiple factors are involved. Irisin, a positive hormone regulator of muscle growth and bone, may play a role. Objectives: To investigate (1) circulating irisin in a series of DM1 and DM2 male patients compared with healthy controls and (2) the relationships between irisin and anthropometric, metabolic and hormonal parameters. Design and study participants: This is a cross-sectional study. Fasting blood samples for glucometabolic, gonadic, bone markers, and irisin were collected from 28 ambulatory DM1, 10 DM2, and 23 age-matched healthy male subjects. Body composition and bone mineralization [bone mineral density (BMD)] were measured by DEXA. Echocardiographic assessment and visceral adiposity, namely, liver and epicardial fat, were investigated by ultrasound. Irisin released from cultured myotubes derived from 3 DM1, 3 DM2, and 3 healthy donors was assayed. Results: Plasma irisin levels were definitely lower in both DM1 and DM2 patients than in controls with no difference between DM1 and DM2. Irisin released from DM1 and DM2 myotubes was similar to that released from myotubes of the non-DM donors, though diabetic DM2 myotubes released more irisin than DM1 myotubes. There was no correlation between irisin and muscle strength or lean mass in both DM1 and DM2 patients. In DM1 patients, plasma irisin levels correlated negatively with oxygen consumption and positively with insulin resistance, while in DM2 patients plasma irisin levels positively correlated with fat mass at arms and legs levels. No correlation with visceral fat, left ventricular mass, and gonadal hormones could be detected. In both DM1 and DM2 patients, legs BMD parameters positively correlated with plasma irisin levels. Conclusion: Plasma irisin is reduced in both DM1 and DM2 male patients likely reflecting muscle mass reduction. Moreover, insulin resistance may contribute to modulation of plasma irisin in DM1 patients. The irisin-mediated cross talk muscle-adipose tissue-bone may be active also in the male myotonic dystrophies' model. PMID- 29184539 TI - Effects on Subclinical Heart Failure in Type 2 Diabetic Subjects on Liraglutide Treatment vs. Glimepiride Both in Combination with Metformin: A Randomized Open Parallel-Group Study. AB - Objective: We aimed to investigate the effect of liraglutide treatment on heart function in type 2 diabetes (T2D) patients with subclinical heart failure. Methods: Randomized open parallel-group trial. 62 T2D patients (45 male) with subclinical heart failure were randomized to either once daily liraglutide 1.8 mg, or glimepiride 4 mg, both add on to metformin 1 g twice a day. Mitral annular systolic (s') and early diastolic (e') velocities were measured at rest and during bicycle ergometer exercise, using tissue Doppler echocardiography. The primary endpoint was 18-week treatment changes in longitudinal functional reserve index (LFRIdiastolic/systolic). Results: Clinical characteristics between groups (liraglutide = 33 vs. glimepiride = 29) were well matched. At baseline left ventricle ejection fraction (53.7 vs. 53.6%) and global longitudinal strain ( 15.3 vs. -16.5%) did not differ between groups. There were no significant differences in mitral flow velocities between groups. For the primary endpoint, there was no treatment change [95% confidence interval] for: LFRIdiastolic (-0.18 vs. -0.53 [-0.28, 2.59; p = 0.19]), or LFRIsystolic (-0.10 vs. -0.18 [-1.0, 1.7; p = 0.54]); for the secondary endpoints, there was a significant treatment change in respect of body weight (-3.7 vs. -0.2 kg [-5.5, -1.4; p = 0.001]), waist circumference (-3.1 vs. -0.8 cm [-4.2, -0.4; p = 0.019]), and heart rate (HR) (6.3 vs. -2.3 bpm [-3.0, 14.2; p = 0.003]), with no such treatment change in hemoglobin A1c levels (-11.0 vs. -9.2 mmol/mol [-7.0, 2.6; p = 0.37]), between groups. Conclusion: 18-week treatment of liraglutide compared with glimepiride did not improve LFRIdiastolic/systolic, but however increased HR. There was a significant treatment change in body weight reduction in favor for liraglutide treatment. PMID- 29184540 TI - Ecogenomics and Taxonomy of Cyanobacteria Phylum. AB - Cyanobacteria are major contributors to global biogeochemical cycles. The genetic diversity among Cyanobacteria enables them to thrive across many habitats, although only a few studies have analyzed the association of phylogenomic clades to specific environmental niches. In this study, we adopted an ecogenomics strategy with the aim to delineate ecological niche preferences of Cyanobacteria and integrate them to the genomic taxonomy of these bacteria. First, an appropriate phylogenomic framework was established using a set of genomic taxonomy signatures (including a tree based on conserved gene sequences, genome to-genome distance, and average amino acid identity) to analyse ninety-nine publicly available cyanobacterial genomes. Next, the relative abundances of these genomes were determined throughout diverse global marine and freshwater ecosystems, using metagenomic data sets. The whole-genome-based taxonomy of the ninety-nine genomes allowed us to identify 57 (of which 28 are new genera) and 87 (of which 32 are new species) different cyanobacterial genera and species, respectively. The ecogenomic analysis allowed the distinction of three major ecological groups of Cyanobacteria (named as i. Low Temperature; ii. Low Temperature Copiotroph; and iii. High Temperature Oligotroph) that were coherently linked to the genomic taxonomy. This work establishes a new taxonomic framework for Cyanobacteria in the light of genomic taxonomy and ecogenomic approaches. PMID- 29184536 TI - Insulin Resistance: Any Role in the Changing Epidemiology of Thyroid Cancer? AB - In the past few decades, the incidence of thyroid cancer (TC), namely of its papillary hystotype (PTC), has shown a steady increase worldwide, which has been attributed at least in part to the increasing diagnosis of early stage tumors. However, some evidence suggests that environmental and lifestyle factors can also play a role. Among the potential risk factors involved in the changing epidemiology of TC, particular attention has been drawn to insulin-resistance and related metabolic disorders, such as obesity, type 2 diabetes, and metabolic syndrome, which have been also rapidly increasing worldwide due to widespread dietary and lifestyle changes. In accordance with this possibility, various epidemiological studies have indeed gathered substantial evidence that insulin resistance-related metabolic disorders might be associated with an increased TC risk either through hyperinsulinemia or by affecting other TC risk factors including iodine deficiency, elevated thyroid stimulating hormone, estrogen dependent signaling, chronic autoimmune thyroiditis, and others. This review summarizes the current literature evaluating the relationship between metabolic disorders characterized by insulin resistance and the risk for TC as well as the possible underlying mechanisms. The potential implications of such association in TC prevention and therapy are discussed. PMID- 29184542 TI - Lysogenic Conversion of the Phytopathogen Ralstonia solanacearum by the P2virus phiRSY1. AB - A P2-like phage phiRSY1 infecting the phytopathogen Ralstonia solanacearum was isolated and characterized. The 40-kb genome of phiRSY1 showed high sequence similarity to the Ralstonia phage phiRSA1 and the GMI1000 prophage phiRSX. The major genomic differences between these phages were the different orientation of the int gene and the gene content close to the cosL. phiRSY1 and phiRSX use a 15 base 3' portion of the serine tRNA(GGA) gene as attB, while phiRSA1 uses a 45 base 3' portion of the arginine tRNA(CCG) gene. The different orientation of int in the genomes means that the gene arrangements in the prophage states are reversed in phiRSY1 and phiRSA1. Several putative gene products of phiRSY1 may affect the bacterium's fitness. phiRSY1 contains an open reading frame (ORF) that seems to encode a protein similar to Vgr in the type VI secretion system of various bacterial species. phiRSY1 lysogens showed phenotypic changes including enhanced twitching motility, large colony formation, and easy aggregation of cells, suggesting involvement of this ORF in the changes. In view of these phage gene arrangements, we surveyed prophages in the genomes of various R. solanacearum strains and found that the P2-like phages of R. solanacearum (14 phages) consist of two major groups: the phiRSY1-type and the phiRSA1-type. The relationships and evolution of these P2-like phages inferred from our data are discussed in detail. PMID- 29184543 TI - Modulation of Microtubule Dynamics Affects Brucella abortus Intracellular Survival, Pathogen-Containing Vacuole Maturation, and Pro-inflammatory Cytokine Production in Infected Macrophages. AB - The microtubule (MT) cytoskeleton regulates several cellular processes related to the immune system. For instance, an intricate intracellular transport mediated by MTs is responsible for the proper localization of vesicular receptors of innate immunity and its adaptor proteins. In the present study, we used nocodazole to induce MTs depolymerization and paclitaxel or recombinant (r) TIR (Toll/interleukin-1 receptor) domain containing protein (TcpB) to induce MT stabilization in bone marrow-derived macrophages infected with Brucella abortus. Following treatment of the cells, we evaluated their effects on pathogen intracellular replication and survival, and in pro-inflammatory cytokine production. First, we observed that intracellular trafficking and maturation of Brucella-containing vesicles (BCVs) is affected by partial destabilization or stabilization of the MTs network. A typical marker of early BCVs, LAMP-1, is retained in late BCVs even 24 h after infection in the presence of low doses of nocodazole or paclitaxel and in the presence of different amounts of rTcpB. Second, microscopy and colony forming unit analysis revealed that bacterial load was increased in infected macrophages treated with lower doses of nocodazole or paclitaxel and with rTcpB compared to untreated cells. Third, innate immune responses were also affected by disturbing MT dynamics. MT depolymerization by nocodazole reduced IL-12 production in infected macrophages. Conversely, rTcpB treated cells augmented IL-12 and IL-1beta secretion in infected cells. In summary, these findings demonstrate that modulation of MTs affects several crucial steps of B. abortus pathogenesis, including BCV maturation, intracellular survival and IL-12 secretion in infected macrophages. PMID- 29184544 TI - Modeling Effects of Temperature, Soil, Moisture, Nutrition and Variety As Determinants of Severity of Pythium Damping-Off and Root Disease in Subterranean Clover. AB - Subterranean clover (Trifolium subterraneum) is a critical pasture legume in Mediterranean regions of southern Australia and elsewhere, including Mediterranean-type climatic regions in Africa, Asia, Australia, Europe, North America, and South America. Pythium damping-off and root disease caused by Pythium irregulare is a significant threat to subterranean clover in Australia and a study was conducted to define how environmental factors (viz. temperature, soil type, moisture and nutrition) as well as variety, influence the extent of damping-off and root disease as well as subterranean clover productivity under challenge by this pathogen. Relationships were statistically modeled using linear and generalized linear models and boosted regression trees. Modeling found complex relationships between explanatory variables and the extent of Pythium damping-off and root rot. Linear modeling identified high-level (4 or 5-way) significant interactions for each dependent variable (dry shoot and root weight, emergence, tap and lateral root disease index). Furthermore, all explanatory variables (temperature, soil, moisture, nutrition, variety) were found significant as part of some interaction within these models. A significant five way interaction between all explanatory variables was found for both dry shoot and root dry weights, and a four way interaction between temperature, soil, moisture, and nutrition was found for both tap and lateral root disease index. A second approach to modeling using boosted regression trees provided support for and helped clarify the complex nature of the relationships found in linear models. All explanatory variables showed at least 5% relative influence on each of the five dependent variables. All models indicated differences due to soil type, with the sand-based soil having either higher weights, greater emergence, or lower disease indices; while lowest weights and less emergence, as well as higher disease indices, were found for loam soil and low temperature. There was more severe tap and lateral root rot disease in higher moisture situations. PMID- 29184541 TI - Antagonistic Microbial Interactions: Contributions and Potential Applications for Controlling Pathogens in the Aquatic Systems. AB - Despite the active and intense treatment of wastewater, pathogenic microorganisms and viruses are frequently introduced into the aquatic environment. For most human pathogens, however, this is a rather hostile place, where starvation, continuous inactivation, and decay generally occur, rather than successful reproduction. Nevertheless, a great diversity of the pathogenic microorganisms can be detected, in particular, in the surface waters receiving wastewater. Pathogen survival depends majorly on abiotic factors such as irradiation, changes in water ionic strength, temperature, and redox state. In addition, inactivation is enhanced by the biotic interactions in the environment. Although knowledge of the antagonistic biotic interactions has been available since a long time, certain underlying processes and mechanisms still remain unclear. Others are well appreciated and increasingly are applied to the present research. Our review compiles and discusses the presently known biotic interactions between autochthonous microbes and pathogens introduced into the aquatic environment, including protozoan grazing, virus-induced bacterial cell lysis, antimicrobial substances, and predatory bacteria. An overview is provided on the present knowledge, as well as on the obvious research gaps. Individual processes that appear promising for future applications in the aquatic environment are presented and discussed. PMID- 29184545 TI - Comparison of the Effects of Phenylhydrazine Hydrochloride and Dicyandiamide on Ammonia-Oxidizing Bacteria and Archaea in Andosols. AB - Dicyandiamide, a routinely used commercial nitrification inhibitor (NI), inhibits ammonia oxidation catalyzed by ammonia monooxygenase (AMO). Phenylhydrazine hydrochloride has shown considerable potential for the development of next generation NIs targeting hydroxylamine dehydrogenase (HAO). The effects of the AMO inhibitor and the HAO inhibitor on ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) present in agricultural soils have not been compared thus far. In the present study, the effects of the two inhibitors on soil nitrification and the abundance of AOA and AOB as well as their community structure were investigated in a soil microcosm using quantitative polymerase chain reaction and pyrosequencing. The net nitrification rates and the growth of AOA and AOB in this soil microcosm were inhibited by both NIs. Both NIs had limited effect on the community structure of AOB and no effect on that of AOA in this soil microcosm. The effects of phenylhydrazine hydrochloride were similar to those of dicyandiamide. These results indicated that organohydrazine-based NIs have potential for the development of next-generation NIs targeting HAO in the future. PMID- 29184546 TI - Amplicon-Metagenomic Analysis of Fungi from Antarctic Terrestrial Habitats. AB - In cold environments such as polar regions, microorganisms play important ecological roles, and most of our knowledge about them comes from studies of cultivable microorganisms. Metagenomic technologies are powerful tools that can give a more comprehensive assessment of microbial communities, and the amplification of rDNA followed by next-generation sequencing has given good results in studies aimed particularly at environmental microorganisms. Culture independent studies of microbiota in terrestrial habitats of Antarctica, which is considered the driest, coldest climate on Earth, are increasing and indicate that micro-diversity is much higher than previously thought. In this work, the microbial diversity of terrestrial habitats including eight islands of the South Shetland Archipelago, two islands on the Antarctic Peninsula and Union Glacier, was studied by amplicon-metagenome analysis. Molecular analysis of the studied localities clustered together the islands of the South Shetland Archipelago, except Greenwich Island, and separated them from the Litchfield and Lagotellerie islands and Union Glacier, which is in agreement with the latitudinal difference among them. Among fungi, 87 genera and 123 species were found, of which species belonging to 37 fungal genera not previously cultivated from Antarctica were detected. Phylogenetic analysis, including the closest BLAST-hit sequences, clustered fungi in 11 classes being the most represented Lecanoromycetes and Eurotiomycetes. PMID- 29184547 TI - Zinc Limitation Induces a Hyper-Adherent Goliath Phenotype in Candida albicans. AB - Pathogenic microorganisms often face acute micronutrient limitation during infection due to the action of host-mediated nutritional immunity. The human fungal pathogen Candida albicans is polymorphic and its morphological plasticity is one of its most widely recognized pathogenicity attributes. Here we investigated the effect of zinc, iron, manganese, and copper limitation on C. albicans morphology. Restriction of zinc specifically resulted in the formation of enlarged, spherical yeasts, a phenotype which we term Goliath cells. This cellular response to zinc restriction was conserved in C. albicans, C. dubliniensis and C. tropicalis, but not in C. parapsilosis, C. lusitaniae or Debaryomyces hansenii, suggesting that it may have emerged in the last common ancestor of these related pathogenic species. Cell wall analysis revealed proportionally more chitin exposure on the Goliath cell surface. Importantly, these cells were hyper-adherent, suggesting a possible role in pathogenicity. Interestingly, the zincophore-encoding gene PRA1 was expressed by Goliath cells in zinc limited media and lack of Pra1 inhibited both cellular enlargement and adhesion. Goliath cells represent a further layer of Candida phenotypic plasticity. PMID- 29184548 TI - Fused IgY Fc and Polysaccharide Adjuvant Enhanced the Immune Effect of the Recombinant VP2 and VP5 Subunits-A Prospect for Improvement of Infectious Bursal Disease Virus Subunit Vaccine. AB - Infectious bursal disease virus (IBDV) is a highly contagious pathogen that causes damage in lymphoid organs and remains a threat to the poultry industry worldwide. Currently, subunit vaccines based on VP2 antigen expressed in prokaryotic systems are widely used in clinical settings. However, the immunogenicity of VP2 vaccines is limited because of their inherent defect that the structure of the antigen expressed in Escherichia coli (E. coli) may be different from its natural conformation. In this study, we fused VP2 and VP5 protective antigen genes and linked the chicken IgY Fc gene onto it. The eukaryotic expression plasmid carrying the fusion gene was transformed into Pichia pastoris (P. pastoris) to express the recombinant VP2-VP5-Fc protein. The recombinant protein was used as immunogen for evaluating immune response, and the recombinant VP2-Fc and VP2 proteins expressed in P. pastoris and the commercial VP2 subunit vaccines were used as controls. Moreover, Taishan Pinus massoniana pollen polysaccharide (TPPPS), an immunomodulator found by our laboratory, was used as adjuvant to investigate its immune modulatory effects on immunogens. Chickens were divided into six groups and inoculated with VP2-VP5-Fc+TPPPS, VP2 VP5-Fc, VP2-Fc, VP2 vaccine, commercial VP2 subunit vaccine, and phosphate buffered saline (PBS). The recombinant VP2 subunit vaccine expressed in P. pastoris exhibited higher immunogenicity than the commercial VP2 subunit vaccine. The VP2-Fc protein showed a better effect than the VP2 protein, and the VP2-VP5 Fc subunit further improved the immune effects. In addition, TPPPS was proved to be a good immunopotentiator for the VP2-VP5-Fc subunit vaccine. Hence, the recombinant VP2-VP5-Fc subunit combined with TPPPS adjuvant exhibits potential as efficient IBDV vaccine to prevent infectious bursal disease. PMID- 29184549 TI - The Immunology of Wild Rodents: Current Status and Future Prospects. AB - Wild animals' immune responses contribute to their evolutionary fitness. These responses are moulded by selection to be appropriate to the actual antigenic environment in which the animals live, but without imposing an excessive energetic demand which compromises other component of fitness. But, exactly what these responses are, and how they compare with those of laboratory animals, has been little studied. Here, we review the very small number of published studies of immune responses of wild rodents, finding general agreement that their humoral (antibody) responses are highly elevated when compared with those of laboratory animals, and that wild rodents' cellular immune system reveals extensive antigenic exposure. In contrast, proliferative and cytokine responses of ex vivo stimulated immune cells of wild rodents are typically depressed compared with those of laboratory animals. Collectively, these responses are appropriate to wild animals' lives, because the elevated responses reflect the cumulative exposure to infection, while the depressed proliferative and cytokine responses are indicative of effective immune homeostasis that minimizes immunopathology. A more comprehensive understanding of the immune ecology of wild animals requires (i) understanding the antigenic load to which wild animals are exposed, and identification of any key antigens that mould the immune repertoire, (ii) identifying immunoregulatory processes of wild animals and the events that induce them, and (iii) understanding the actual resource state of wild animals, and the immunological consequences that flow from this. Together, by extending studies of wild rodents, particularly addressing these questions (while drawing on our immunological understanding of laboratory animals), we will be better able to understand how rodents' immune responses contribute to their fitness in the wild. PMID- 29184551 TI - Interleukin-4 Supports the Suppressive Immune Responses Elicited by Regulatory T Cells. AB - Interleukin-4 (IL-4) has been considered as one of the tolerogenic cytokines in many autoimmune animal models and clinical settings. Despite its role in antagonizing pathogenic Th1 responses, little is known about whether IL-4 possesses functions that affect regulatory T cells (Tregs). Tregs are specialized cells responsible for the maintenance of peripheral tolerance through their immune modulatory capabilities. Interestingly, it has been suggested that IL-4 supplement at a high concentration protects responder T cells (Tresps) from Treg mediated immune suppression. In addition, such supplement also impedes TGF-beta induced Treg differentiation in vitro. However, these phenomena may contradict the tolerogenic role of IL-4, and the effects of IL-4 on Tregs are therefore needed to be further elucidated. In this study, we utilized IL-4 knockout (KO) mice to validate the role of IL-4 on Treg-mediated immune suppression. Although IL-4 KO and control animals harbor similar frequencies of Tregs, Tregs from IL-4 KO mice weakly suppressed autologous Tresp activation. In addition, IL-4 deprivation impaired the ability of Tregs to modulate immune response, whereas IL 4 supplementation reinforced IL-4 KO Tregs in their function in suppressing Tresps. Finally, the presence of IL-4 was associated with increased cell survival and granzyme expression of Tregs. These results suggest the essential role of IL 4 in supporting Treg-mediated immune suppression, which may benefit the development of therapeutic strategies for autoimmune diseases. PMID- 29184553 TI - Tumor Necrosis Factor-Alpha Targeting Can Protect against Arthritis with Low Sensitization to Infection. AB - Tumor necrosis factor-alpha (TNF-alpha) blockade is an effective treatment for rheumatoid arthritis (RA) and other inflammatory diseases, but in patients, it is associated with reduced resistance to the infectious agents Mycobacterium tuberculosis and Listeria monocytogenes, among others. Our goal was to model infection and arthritis in mice and to compare etanercept, a currently used anti TNF-alpha inhibitor, to an anti-TNF-alpha vaccine. We developed a murine surrogate of the TNF-alpha kinoid and produced an anti-murine TNF-alpha vaccine (TNFKi) composed of keyhole limpet hemocyanin conjugated to TNF-alpha, which resulted in anti-TNF-alpha antibody production in mice. We also used etanercept (a soluble receptor of TNF commonly used to treat RA) as a control of TNF neutralization. In a mouse model of collagen-induced arthritis, TNFKi protected against inflammation similar to etanercept. In a mouse model of acute L. monocytogenes infection, all TNFKi-treated mice showed cleared bacterial infection and survived, whereas etanercept-treated mice showed large liver granulomas and quickly died. Moreover, TNFKi mice infected with the virulent H37Rv M. tuberculosis showed resistance to infection, in contrast with etanercept treated mice or controls. Depending on the TNF-alpha blockade strategy, treating arthritis with a TNF-alpha inhibitor could result in a different profile of infection suceptibility. Our TNFKi vaccine allowed for a better remaining host defense than did etanercept.

AB - Natural killer (NK) cells are effector lymphocytes of the innate immune system that are able to mount a multifaceted antiviral response within hours following infection. This is achieved through an array of cell surface receptors surveilling host cells for alterations in human leukocyte antigen class I (HLA-I) expression and other ligands as signs of viral infection, malignant transformation, and cellular stress. This interaction between HLA-I ligands and NK-cell receptor is not only important for recognition of diseased cells but also mediates tuning of NK-cell-effector functions. HIV-1 alters the expression of HLA I ligands on infected cells, rendering them susceptible to NK cell-mediated killing. However, over the past years, various HIV-1 evasion strategies have been discovered to target NK-cell-receptor ligands and allow the virus to escape from NK cell-mediated immunity. While studies have been mainly focusing on the role of polymorphic HLA-A, -B, and -C molecules, less is known about how HIV-1 affects the more conserved, non-classical HLA-I molecules HLA-E, -G, and -F. In this review, we will focus on the recent progress in understanding the role of non classical HLA-I ligands in NK cell-mediated recognition of HIV-1-infected cells. PMID- 29184554 TI - IL-17 and TNF-alpha Are Key Mediators of Moraxella catarrhalis Triggered Exacerbation of Allergic Airway Inflammation. AB - Alterations of the airway microbiome are often associated with pulmonary diseases. For example, detection of the bacterial pathogen Moraxella catarrhalis in the upper airways is linked with an increased risk to develop or exacerbate asthma. However, the mechanisms by which M. catarrhalis augments allergic airway inflammation (AAI) remain unclear. We here characterized the cellular and soluble mediators of M. catarrhalis triggered excacerbation of AAI in wt and IL-17 deficient as well as in animals treated with TNF-alpha and IL-6 neutralizing antibodies. We compared the type of inflammatory response in M. catarrhalis infected, house dust mite (HDM)-allergic and animals infected with M. catarrhalis at different time points of HDM sensitization. We found that airway infection of mice with M. catarrhalis triggers a strong inflammatory response with massive neutrophilic infiltrates, high amounts of IL-6 and TNF-alpha and moderate levels of CD4+ T-cell-derived IFN-gamma and IL-17. If bacterial infection occurred during HDM allergen sensitization, the allergic airway response was exacerbated, particularly by the expansion of Th17 cells and increased TNF-alpha levels. Neutralization of IL-17 or TNF-alpha but not IL-6 resulted in accelerated clearance of M. catarrhalis and effectively prevented infection-induced exacerbation of AAI. Taken together, our data demonstrate an essential role for TNF-alpha and IL-17 in infection-triggered exacerbation of AAI. PMID- 29184552 TI - Multifaceted Effects of Extracellular Adenosine Triphosphate and Adenosine in the Tumor-Host Interaction and Therapeutic Perspectives. AB - Cancer is still one of the world's most pressing health-care challenges, leading to a high number of deaths worldwide. Immunotherapy is a new developing therapy that boosts patient's immune system to fight cancer by modifying tumor-immune cells interaction in the tumor microenvironment (TME). Extracellular adenosine triphosphate (eATP) and adenosine (Ado) are signaling molecules released in the TME that act as modulators of both immune and tumor cell responses. Extracellular adenosine triphosphate and Ado activate purinergic type 2 (P2) and type 1 (P1) receptors, respectively, triggering the so-called purinergic signaling. The concentration of eATP and Ado within the TME is tightly controlled by several cell-surface ectonucleotidases, such as CD39 and CD73, the major ecto-enzymes expressed in cancer cells, immune cells, stromal cells, and vasculature, being CD73 also expressed on tumor-associated fibroblasts. Once accumulated in the TME, eATP boosts antitumor immune response, while Ado attenuates or suppresses immunity against the tumor. In addition, both molecules can mediate growth stimulation or inhibition of the tumor, depending on the specific receptor activated. Therefore, purinergic signaling is able to modulate both tumor and immune cells behavior and, consequently, the tumor-host interaction and disease progression. In this review, we discuss the role of purinergic signaling in the host-tumor interaction detailing the multifaceted effects of eATP and Ado in the inflammatory TME. Moreover, we present recent findings into the application of purinergic-targeting therapy as a potential novel option to boost antitumor immune responses in cancer. PMID- 29184555 TI - Innate Immunity to Respiratory Infection in Early Life. AB - Early life is a period of particular susceptibility to respiratory infections and symptoms are frequently more severe in infants than in adults. The neonatal immune system is generally held to be deficient in most compartments; responses to innate stimuli are weak, antigen-presenting cells have poor immunostimulatory activity and adaptive lymphocyte responses are limited, leading to poor immune memory and ineffective vaccine responses. For mucosal surfaces such as the lung, which is continuously exposed to airborne antigen and to potential pathogenic invasion, the ability to discriminate between harmless and potentially dangerous antigens is essential, to prevent inflammation that could lead to loss of gaseous exchange and damage to the developing lung tissue. We have only recently begun to define the differences in respiratory immunity in early life and its environmental and developmental influences. The innate immune system may be of relatively greater importance than the adaptive immune system in the neonatal and infant period than later in life, as it does not require specific antigenic experience. A better understanding of what constitutes protective innate immunity in the respiratory tract in this age group and the factors that influence its development should allow us to predict why certain infants are vulnerable to severe respiratory infections, design treatments to accelerate the development of protective immunity, and design age specific adjuvants to better boost immunity to infection in the lung. PMID- 29184556 TI - GATA3 Regulates the Development and Functions of Innate Lymphoid Cell Subsets at Multiple Stages. AB - Innate lymphoid cells (ILCs) are regarded as the innate counterpart of effector CD4 T helper (Th) cells. Just as Th cells, ILCs are classified into distinct subsets based on their functions that are delivered mainly through effector cytokine production. Both ILCs and Th cells play critical roles in various protective immune responses and inflammatory diseases. Similar to Th cell differentiation, the development of ILC subsets depends on several master transcription factors, among which GATA3 is critical for the development and maintenance of type 2 ILCs (ILC2s). However, GATA3 is expressed by all ILC subsets and ILC progenitors, albeit at different levels. In a striking parallel with GATA3 function in T cell development and differentiation, GATA3 also has multiple functions in different ILCs at various stages. In this review, I will discuss how quantitative and dynamic expression of GATA3 regulates the development and functions of ILC subsets. PMID- 29184557 TI - Combined Genomic and Genetic Data Integration of Major Agronomical Traits in Bread Wheat (Triticum aestivum L.). AB - The high resolution integration of bread wheat genetic and genomic resources accumulated during the last decades offers the opportunity to unveil candidate genes driving major agronomical traits to an unprecedented scale. We combined 27 public quantitative genetic studies and four genetic maps to deliver an exhaustive consensus map consisting of 140,315 molecular markers hosting 221, 73, and 82 Quantitative Trait Loci (QTL) for respectively yield, baking quality, and grain protein content (GPC) related traits. Projection of the consensus genetic map and associated QTLs onto the wheat syntenome made of 99,386 genes ordered on the 21 chromosomes delivered a complete and non-redundant repertoire of 18, 8, 6 metaQTLs for respectively yield, baking quality and GPC, altogether associated to 15,772 genes (delivering 28,630 SNP-based makers) including 37 major candidates. Overall, this study illustrates a translational research approach in transferring information gained from grass relatives to dissect the genomic regions hosting major loci governing key agronomical traits in bread wheat, their flanking markers and associated candidate genes to be now considered as a key resource for breeding programs. PMID- 29184558 TI - Application of Genome Wide Association and Genomic Prediction for Improvement of Cacao Productivity and Resistance to Black and Frosty Pod Diseases. AB - Chocolate is a highly valued and palatable confectionery product. Chocolate is primarily made from the processed seeds of the tree species Theobroma cacao. Cacao cultivation is highly relevant for small-holder farmers throughout the tropics, yet its productivity remains limited by low yields and widespread pathogens. A panel of 148 improved cacao clones was assembled based on productivity and disease resistance, and phenotypic single-tree replicated clonal evaluation was performed for 8 years. Using high-density markers, the diversity of clones was expressed relative to 10 known ancestral cacao populations, and significant effects of ancestry were observed in productivity and disease resistance. Genome-wide association (GWA) was performed, and six markers were significantly associated with frosty pod disease resistance. In addition, genomic selection was performed, and consistent with the observed extensive linkage disequilibrium, high predictive ability was observed at low marker densities for all traits. Finally, quantitative trait locus mapping and differential expression analysis of two cultivars with contrasting disease phenotypes were performed to identify genes underlying frosty pod disease resistance, identifying a significant quantitative trait locus and 35 differentially expressed genes using two independent differential expression analyses. These results indicate that in breeding populations of heterozygous and recently admixed individuals, mapping approaches can be used for low complexity traits like pod color cacao, or in other species single gene disease resistance, however genomic selection for quantitative traits remains highly effective relative to mapping. Our results can help guide the breeding process for sustainable improved cacao productivity. PMID- 29184559 TI - State of the Art: trxG Factor Regulation of Post-embryonic Plant Development. AB - Multicellular organisms rely on the precise and consistent regulation of gene expression to direct their development in tissue- and cell-type specific patterns. This regulatory activity involves arrays of DNA-binding transcription factors and epigenetic factors that modify chromatin structure. Among the chromatin modifiers, trithorax (trxG) and Polycomb (PcG) group proteins play important roles in orchestrating the stable activation and repression of gene expression, respectively. These proteins have generally antagonistic functions in maintaining cell and tissue homeostasis as well as in mediating widespread transcriptional reprogramming during developmental transitions. Plants utilize multiple trxG factors to regulate gene transcription as they modulate their development in response to both endogenous and environmental cues. Here, I will discuss the roles of trxG factors and their associated proteins in post-embryonic plant development. PMID- 29184560 TI - Volatile Metabolomic Composition of Vitex Species: Chemodiversity Insights and Acaricidal Activity. AB - The Vitex genus (Lamiaceae) produces a plethora of metabolites that include ecdysteroids and terpenoids, some of which have demonstrated insect repellent properties. The volatile composition of several members of this genus has not been chemically defined, as many taxa are endemic to remote ecosystems. In this study, leaves were collected from the northeast of Brazil from Vitex capitata, V. megapotamica, V. gardneriana, and V. rufescens plants and examined for their chemical profile via GC-MS/FID of essential oil extracts. The analyses showed a diversity of terpenoids. Of particular note were seven-member ring sesquiterpenes which were present in great abundance; a dendrogram showed clades separating by the production of bicyclogermacrene, aromadendrane and 5,10-cycloaromadendrane sesquiterpenoids for the four species. Comparison of volatile metabolite profiles to 13 other Vitex species showed strong similarities in the production of some monoterpenes, but varied by their production of larger terpenes, especially those with gem-dimethylcyclopropyl subunits on seven-member ring compounds. From this work, we suggest that the sesquiterpene skeleton with seven member rings is a good chemosystematic biomarker candidate for the Vitex genus. Separation using this biomarker was then validated using Inter-Simple Sequence Repeat profiling. Lastly, experiments examining the toxicity of these four oils against the coconut mite Aceria guerreronis showed that only the oil of V. gardneriana had strong acaricidal activity, with an LC50 of 0.85 mg/mL, thus demonstrating its potential for use as a natural pesticide. PMID- 29184561 TI - Characterization of a Thermo-Inducible Chlorophyll-Deficient Mutant in Barley. AB - Leaf color is an important trait for not only controlling crop yield but also monitoring plant status under temperature stress. In this study, a thermo inducible chlorophyll-deficient mutant, named V-V-Y, was identified from a gamma radiated population of the barley variety Vlamingh. The leaves of the mutant were green under normal growing temperature but turned yellowish under high temperature in the glasshouse experiment. The ratio of chlorophyll a and chlorophyll b in the mutant declined much faster in the first 7-9 days under heat treatment. The leaves of V-V-Y turned yellowish but took longer to senesce under heat stress in the field experiment. Genetic analysis indicated that a single nuclear gene controlled the mutant trait. The mutant gene (vvy) was mapped to the long arm of chromosome 4H between SNP markers 1_0269 and 1_1531 with a genetic distance of 2.2 cM and a physical interval of 9.85 Mb. A QTL for grain yield was mapped to the same interval and explained 10.4% of the yield variation with a LOD score of 4. This QTL is coincident with the vvy gene interval that is responsible for the thermo-inducible chlorophyll-deficient trait. Fine mapping, based on the barley reference genome sequence, further narrowed the vvy gene to a physical interval of 0.428 Mb with 11 annotated genes. This is the first report of fine mapping a thermo-inducible chlorophyll-deficient gene in barley. PMID- 29184563 TI - The Kinase ERULUS Controls Pollen Tube Targeting and Growth in Arabidopsis thaliana. AB - In this paper, we describe the role of the receptor-like kinase ERULUS (ERU) in PT growth of Arabidopsis thaliana. In silico analysis and transcriptional reporter lines revealed that ERU is only expressed in pollen and root hairs (RHs), making it a tip growth-specific kinase. Deviations from Mendelian inheritance were observed in the offspring of self-pollinated heterozygous eru plants. We found that in vivo eru PT targeting was disturbed, providing a possible explanation for the observed decrease in eru fertilization competitiveness. Extracellular calcium perception and intracellular calcium dynamics lie at the basis of in vivo pollen tube (PT) tip growth and guidance. In vitro, ERU loss-of-function lines displayed no obvious PT phenotype, unless grown on low extracellular calcium ([Ca2+]ext) medium. When grown at 12 the normal [Ca2+]ext, eru PTs grew 37% slower relative to WT PTs. Visualization of cytoplasmic [Ca2+]cyt oscillations using the Yellow Cameleon 3.6 (YC3.6) calcium sensor showed that, unlike in WT PTs, eru apical [Ca2+]cyt oscillations occur at a lower frequency when grown at lower [Ca2+]ext, consistent with the observed reduced growth velocity. Our results show that the tip growth-specific kinase ERULUS is involved in regulating Ca2+-dependent PT growth, and most importantly, fertilization efficiency through successful PT targeting to the ovules. PMID- 29184562 TI - De novo Transcriptome Assembly and Comparison of C3, C3-C4, and C4 Species of Tribe Salsoleae (Chenopodiaceae). AB - C4 photosynthesis is a carbon-concentrating mechanism that evolved independently more than 60 times in a wide range of angiosperm lineages. Among other alterations, the evolution of C4 from ancestral C3 photosynthesis requires changes in the expression of a vast number of genes. Differential gene expression analyses between closely related C3 and C4 species have significantly increased our understanding of C4 functioning and evolution. In Chenopodiaceae, a family that is rich in C4 origins and photosynthetic types, the anatomy, physiology and phylogeny of C4, C2, and C3 species of Salsoleae has been studied in great detail, which facilitated the choice of six samples of five representative species with different photosynthetic types for transcriptome comparisons. mRNA from assimilating organs of each species was sequenced in triplicates, and sequence reads were de novo assembled. These novel genetic resources were then analyzed to provide a better understanding of differential gene expression between C3, C2 and C4 species. All three analyzed C4 species belong to the NADP ME type as most genes encoding core enzymes of this C4 cycle are highly expressed. The abundance of photorespiratory transcripts is decreased compared to the C3 and C2 species. Like in other C4 lineages of Caryophyllales, our results suggest that PEPC1 is the C4-specific isoform in Salsoleae. Two recently identified transporters from the PHT4 protein family may not only be related to the C4 syndrome, but also active in C2 photosynthesis in Salsoleae. In the two populations of the C2 species S. divaricata transcript abundance of several C4 genes are slightly increased, however, a C4 cycle is not detectable in the carbon isotope values. Most of the core enzymes of photorespiration are highly increased in the C2 species compared to both C3 and C4 species, confirming a successful establishment of the C2 photosynthetic pathway. Furthermore, a function of PEP-CK in C2 photosynthesis appears likely, since PEP-CK gene expression is not only increased in S. divaricata but also in C2 species of other groups. PMID- 29184564 TI - The Molybdenum Cofactor Biosynthesis Network: In vivo Protein-Protein Interactions of an Actin Associated Multi-Protein Complex. AB - Survival of plants and nearly all organisms depends on the pterin based molybdenum cofactor (Moco) as well as its effective biosynthesis and insertion into apo-enzymes. To this end, both the central Moco biosynthesis enzymes are characterized and the conserved four-step reaction pathway for Moco biosynthesis is well-understood. However, protection mechanisms to prevent degradation during biosynthesis as well as transfer of the highly oxygen sensitive Moco and its intermediates are not fully enlightened. The formation of protein complexes involving transient protein-protein interactions is an efficient strategy for protected metabolic channelling of sensitive molecules. In this review, Moco biosynthesis and allocation network is presented and discussed. This network was intensively studied based on two in vivo interaction methods: bimolecular fluorescence complementation (BiFC) and split-luciferase. Whereas BiFC allows localisation of interacting partners, split-luciferase assay determines interaction strengths in vivo. Results demonstrate (i) interaction of Cnx2 and Cnx3 within the mitochondria and (ii) assembly of a biosynthesis complex including the cytosolic enzymes Cnx5, Cnx6, Cnx7, and Cnx1, which enables a protected transfer of intermediates. The whole complex is associated with actin filaments via Cnx1 as anchor protein. After biosynthesis, Moco needs to be handed over to the specific apo-enzymes. A potential pathway was discovered. Molybdenum containing enzymes of the sulphite oxidase family interact directly with Cnx1. In contrast, the xanthine oxidoreductase family acquires Moco indirectly via a Moco binding protein (MoBP2) and Moco sulphurase ABA3. In summary, the uncovered interaction matrix enables an efficient transfer for intermediate and product protection via micro-compartmentation. PMID- 29184565 TI - A Novel QTL for Powdery Mildew Resistance in Nordic Spring Barley (Hordeum vulgare L. ssp. vulgare) Revealed by Genome-Wide Association Study. AB - The powdery mildew fungus, Blumeria graminis f. sp. hordei is a worldwide threat to barley (Hordeum vulgare L. ssp. vulgare) production. One way to control the disease is by the development and deployment of resistant cultivars. A genome wide association study was performed in a Nordic spring barley panel consisting of 169 genotypes, to identify marker-trait associations significant for powdery mildew. Powdery mildew was scored during three years (2012-2014) in four different locations within the Nordic region. There were strong correlations between data from all locations and years. In total four QTLs were identified, one located on chromosome 4H in the same region as the previously identified mlo locus and three on chromosome 6H. Out of these three QTLs identified on chromosome 6H, two are in the same region as previously reported QTLs for powdery mildew resistance, whereas one QTL appears to be novel. The top NCBI BLASTn hit of the SNP markers within the novel QTL predicted the responsible gene to be the 26S proteasome regulatory subunit, RPN1, which is required for innate immunity and powdery mildew-induced cell death in Arabidopsis. The results from this study have revealed SNP marker candidates that can be exploited for use in marker assisted selection and stacking of genes for powdery mildew resistance in barley. PMID- 29184566 TI - Selection Signatures in the First Exon of Paralogous Receptor Kinase Genes from the Sym2 Region of the Pisum sativum L. Genome. AB - During the initial step of the symbiosis between legumes (Fabaceae) and nitrogen fixing bacteria (rhizobia), the bacterial signal molecule known as the Nod factor (nodulation factor) is recognized by plant LysM motif-containing receptor-like kinases (LysM-RLKs). The fifth chromosome of barrel medic (Medicago truncatula Gaertn.) contains a cluster of paralogous LysM-RLK genes, one of which is known to participate in symbiosis. In the syntenic region of the pea (Pisum sativum L.) genome, three genes have been identified: PsK1 and PsSym37, two symbiosis-related LysM-RLK genes with known sequences, and the unsequenced PsSym2 gene which presumably encodes a LysM-RLK and is associated with increased selectivity to certain Nod factors. In this work, we identified a new gene encoding a LysM-RLK, designated as PsLykX, within the Sym2 genomic region. We sequenced the first exons (corresponding to the protein receptor domain) of PsSym37, PsK1, and PsLykX from a large set of pea genotypes of diverse origin. The nucleotide diversity of these fragments was estimated and groups of haplotypes for each gene were revealed. Footprints of selection pressure were detected via comparative analyses of SNP distribution across the first exons of these genes and their homologs MtLYK2, MtLYK3, and MtLYK4 from M. truncatula retrieved from the Medicago Hapmap project. Despite the remarkable similarity among all the studied genes, they exhibited contrasting selection signatures, possibly pointing to diversification of their functions. Signatures of balancing selection were found in LysM1 encoding parts of PsSym37 and PsK1, suggesting that the diversity of these parts may be important for pea LysM-RLKs. The first exons of PsSym37 and PsK1 displayed signatures of purifying selection, as well as MtLYK2 of M. truncatula. Evidence of positive selection affecting primarily LysM domains was found in all three investigated M. truncatula genes, as well as in the pea gene PsLykX. The data suggested that PsLykX is a promising candidate for PsSym2, which has remained elusive for more than 30 years. PMID- 29184567 TI - Ecological Factors Affecting Infection Risk and Population Genetic Diversity of a Novel Potyvirus in Its Native Wild Ecosystem. AB - Increasing evidence indicates that there is ample diversity of plant virus species in wild ecosystems. The vast majority of this diversity, however, remains uncharacterized. Moreover, in these ecosystems the factors affecting plant virus infection risk and population genetic diversity, two traits intrinsically linked to virus emergence, are largely unknown. Along 3 years, we have analyzed the prevalence and diversity of plant virus species from the genus Potyvirus in evergreen oak forests of the Iberian Peninsula, the main wild ecosystem in this geographic region and in the entire Mediterranean basin. During this period, we have also measured plant species diversity, host density, plant biomass, temperature, relative humidity, and rainfall. Results indicated that potyviruses were always present in evergreen oak forests, with a novel virus species explaining the largest fraction of potyvirus-infected plants. We determined the genomic sequence of this novel virus and we explored its host range in natural and greenhouse conditions. Natural host range was limited to the perennial plant mountain rue (Ruta montana), commonly found in evergreen oak forests of the Iberian Peninsula. In this host, the virus was highly prevalent and was therefore provisionally named mediterranean ruda virus (MeRV). Focusing in this natural host-virus interaction, we analyzed the ecological factors affecting MeRV infection risk and population genetic diversity in its native wild ecosystem. The main predictor of virus infection risk was the host density. MeRV prevalence was the major factor determining genetic diversity and selection pressures in the virus populations. This observation supports theoretical predictions assigning these two traits a key role in parasite epidemiology and evolution. Thus, our analyses contribute both to characterize viral diversity and to understand the ecological determinants of virus population dynamics in wild ecosystems. PMID- 29184568 TI - Metabolic Origins and Transport of Vitamin E Biosynthetic Precursors. AB - Tocochromanols are organic compounds mostly produced by photosynthetic organisms that exhibit vitamin E activity in animals. They result from the condensation of homogentisate with four different polyprenyl side chains derived all from geranylgeranyl pyrophosphate. The core tocochromanol biosynthesis has been investigated in several photosynthetic organisms and is now well-characterized. In contrast, our current knowledge of the biosynthesis and transport of tocochromanol biosynthetic precursors is much more limited. While tocochromanol synthesis occurs in plastids, converging genetic data in Arabidopsis and soybean demonstrate that the synthesis of the polar precursor homogentisate is located in the cytoplasm. These data implies that tocochromanol synthesis involves several plastidic membrane transporter(s) that remain to be identified. In addition, the metabolic origin of the lipophilic isoprenoid precursor is not fully elucidated. While some genetic data exclusively attribute the synthesis of the prenyl component of tocochromanols to the plastidic methyl erythritol phosphate pathway, multiple lines of evidence provided by feeding experiments and metabolic engineering studies indicate that it might partially originate from the cytoplasmic mevalonate pathway. Although this question is still open, these data demonstrate the existence of membrane transporter(s) capable of importing cytosolic polyprenyl pyrophosphate such as farnesyl pyrophosphate into plastids. Since the availability of both homogentisate and polyprenyl pyrophosphates are currently accepted as major mechanisms controlling the type and amount of tocochromanols produced in plant tissues, we summarized our current knowledge and research gaps concerning the biosynthesis, metabolic origins and transport of tocochromanol biosynthetic precursors in plant cells. PMID- 29184570 TI - Opium, an important risk factor for deep vein thrombosis patients. PMID- 29184569 TI - The Seed Repair Response during Germination: Disclosing Correlations between DNA Repair, Antioxidant Response, and Chromatin Remodeling in Medicago truncatula. AB - This work provides novel insights into the effects caused by the histone deacetylase inhibitor trichostatin A (TSA) during Medicago truncatula seed germination, with emphasis on the seed repair response. Seeds treated with H2O and TSA (10 and 20 MUM) were collected during imbibition (8 h) and at the radicle protrusion phase. Biometric data showed delayed germination and impaired seedling growth in TSA-treated samples. Comet assay, performed on radicles at the protrusion phase and 4-days old M. truncatula seedlings, revealed accumulation of DNA strand breaks upon exposure to TSA. Activation of DNA repair toward TSA mediated genotoxic damage was evidenced by the up-regulation of MtOGG1(8 OXOGUANINE GLYCOSYLASE/LYASE) gene involved in the removal of oxidative DNA lesions, MtLIGIV(LIGASE IV) gene, a key determinant of seed quality, required for the rejoining of DNA double strand breaks and TDP(TYROSYL-DNA PHOSPHODIESTERASE) genes encoding the multipurpose DNA repair enzymes tyrosyl-DNA phosphodiesterases. Since radical scavenging can prevent DNA damage, the specific antioxidant activity (SAA) was measured by DPPH (1,1-diphenyl-2-picrylhydrazyl) and Folin-Ciocalteu reagent assays. Fluctuations of SAA were observed in TSA treated seeds/seedlings concomitant with the up-regulation of antioxidant genes MtSOD(SUPEROXIDE DISMUTASE, MtAPX(ASCORBATE PEROXIDASE) and MtMT2(TYPE 2 METALLOTHIONEIN). Chromatin remodeling, required to facilitate the access of DNA repair enzymes at the damaged sites, is also part of the multifaceted seed repair response. To address this aspect, still poorly explored in plants, the MtTRRAP(TRANSFORMATION/TRANSACTIVATION DOMAIN-ASSOCIATED PROTEIN) gene was analyzed. TRRAP is a transcriptional adaptor, so far characterized only in human cells where it is needed for the recruitment of histone acetyltransferase complexes to chromatin during DNA repair. The MtTRRAP gene and the predicted interacting partners MtHAM2 (HISTONE ACETYLTRANSFERASE OF THE MYST FAMILY) and MtADA2A (TRANSCRIPTIONAL ADAPTOR) showed tissue- and dose-dependent fluctuations in transcript levels. PCA (Principal Component Analysis) and correlation analyses suggest for a new putative link between DNA repair and chromatin remodeling that involves MtOGG1 and MtTRRAP genes, in the context of seed germination. Interesting correlations also connect DNA repair and chromatin remodeling with antioxidant players and proliferation markers. PMID- 29184571 TI - Myocardial bridge over the left anterior descending coronary artery: A case report and review of the literature. AB - Myocardial bridging (MB) is considered as a topic of high interest since its occurrence in different studies is statistically significant, and the clinical manifestations of this phenomenon are complicated with cardiovascular diseases. Whether the MB participates in heart diseases and has a decisive effect to life threatening situations is still under research, and many studies have been conducted to clarify the abovementioned question. A case report with a MB on the left anterior descending coronary artery is presented in the current study, and a review of the literature is provided as well. Cardiologists as well thoracic surgeons and radiologists should bear in their mind the potential presence of such variant during interpretation of angiographies and multidetector-computed tomography. PMID- 29184572 TI - Compliance with continuous positive airway pressure in Persian patients with obstructive sleep apnea. AB - Background: Obstructive sleep apnea (OSA) is defined by recurrent apnea and hypopnea during sleep. The main treatment of OSA is continuous positive airway pressure (CPAP). Adherence to CPAP is challenging and depends on multiple factors. This study was designed to evaluate the compliance with CPAP in patients with OSA. Materials and Methods: This was a prospective observational study including 106 patients with confirmed OSA by a standard polysomnography. We recorded CPAP usage hours after 7 and 90 days by a smart card. We compared the adherence of the patients with respect to body mass index (BMI), gender, smoking status, living area, and education level. Results: Patients in the 18-45 years' age group had higher compliance in mean (standard deviation) daily use of CPAP (0.93 [0.40] h) compared to the other age groups (P < 0.001). Patients with BMI >35 had better compliance (1.13 [0.44]) than the other patients (P < 0.001). Furthermore, nonsmokers and highly educated patients had better compliance compared to the others (P < 0.001). Conclusion: Age, BMI, education, and smoking are important factors in adherence to CPAP in patients with OSA. PMID- 29184573 TI - Comparing of Cox model and parametric models in analysis of effective factors on event time of neuropathy in patients with type 2 diabetes. AB - Background: Cox proportional hazard model is the most common method for analyzing the effects of several variables on survival time. However, under certain circumstances, parametric models give more precise estimates to analyze survival data than Cox. The purpose of this study was to investigate the comparative performance of Cox and parametric models in a survival analysis of factors affecting the event time of neuropathy in patients with type 2 diabetes. Materials and Methods: This study included 371 patients with type 2 diabetes without neuropathy who were registered at Fereydunshahr diabetes clinic. Subjects were followed up for the development of neuropathy between 2006 to March 2016. To investigate the factors influencing the event time of neuropathy, significant variables in univariate model (P < 0.20) were entered into the multivariate Cox and parametric models (P < 0.05). In addition, Akaike information criterion (AIC) and area under ROC curves were used to evaluate the relative goodness of fitted model and the efficiency of each procedure, respectively. Statistical computing was performed using R software version 3.2.3 (UNIX platforms, Windows and MacOS). Results: Using Kaplan-Meier, survival time of neuropathy was computed 76.6 +/- 5 months after initial diagnosis of diabetes. After multivariate analysis of Cox and parametric models, ethnicity, high-density lipoprotein and family history of diabetes were identified as predictors of event time of neuropathy (P < 0.05). Conclusion: According to AIC, "log-normal" model with the lowest Akaike's was the best-fitted model among Cox and parametric models. According to the results of comparison of survival receiver operating characteristics curves, log-normal model was considered as the most efficient and fitted model. PMID- 29184574 TI - Evaluation of response to hepatitis B vaccine in Iranian 6-18-year-old students. AB - Background: Hepatitis B is a dangerous disease with high morbidity and mortality rates all around the world. Vaccination is the most important way to its prevention and control. This cross-sectional study was carried out to study the levels of immunogenicity to hepatitis B vaccine in students. Materials and Methods: Six hundred and forty-four students aged 6-18 years including 316 girls and 328 boys were selected from the Chaharmahal Va Bakhtiari province. Selected students had been received three doses of recombinant vaccine (0, 1, and 6 months). Blood samples were taken and the titers of hepatitis B surface antigen were studied. Results: From a total of 644 students, 396 (61.5%) had a titer lesser than 10 mIu/ml and 248 (38.5%) had a titer higher than 10 mIu/ml. Therefore, the level of respond to vaccine with 95% confidence was 38.5% (34.7% 42.4%). Levels of respond to vaccine were related to age, body mass index (BMI), and educational level and were not related to sex and habit of students. Conclusion: Reverse significant relation was seen between the respond to vaccine and age and BMI in a way which the titers of antibody were lower in students with higher age and BMI. PMID- 29184575 TI - Acquired tumor resistance to antiangiogenic therapy: Mechanisms at a glance. AB - Angiogenesis is critical for oxygen and nutrient delivery to proliferating tumor cells. Therefore, as angiogenesis is required and vital for the tumor growth and metastasis. Antiangiogenic therapy is considered to be beneficial for tumor growth prevention due to starvation of tumor of oxygen and nutrients, but in some cases, the benefits are not permanent. Tyrosine kinase inhibitors and many other agents often target angiogenesis through inhibition of the vascular endothelial growth factor (VEGF) pathway. Although preclinical studies showed satisfactory outcomes in tumor growth inhibition, antiangiogenic therapy in the clinical setting may not be effective. The resistance observed in several tumor types through alternative angiogenic "escape" pathways contributes to restoration of tumor growth and may induce progression, enhancement of invasion, and metastasis. Therefore, activation of major compensatory angiogenic pathways, sustaining tumor angiogenesis during VEGF blockade contributing to the recurrence of tumor growth overcome antiangiogenic strategies. In this review, we summarize the novel mechanisms involved in evasive resistance to antiangiogenic therapies and represent different cancer types which have the ability to adapt to VEGF inhibition achieving resistance to antiangiogenic therapy through these adaptive mechanisms.

PMID- 29184576 TI - The relationship between food insecurity with cardiovascular risk markers and metabolic syndrome components in patients with diabetes: A population-based study from Kerman coronary artery disease risk study. AB - Background: We sought the prevalence of food insecurity and whether cardiovascular risk markers and metabolic syndrome components are significantly different in categories of food insecurity in patients with type 2 diabetes. Materials and Methods: In this cross-sectional study, 520 patients with type 2 diabetes from the Kerman coronary artery disease risk study aged between 23 and 87 years (60.8 +/- 11.4) who selected by one-stage cluster sampling were assigned into four groups of "food secure" and "mild," "moderate," and "severe" food insecure. Household food insecurity was assessed by a 9-item household food insecurity access scale questionnaire. Results: The prevalence of food security and mild, moderate, and severe food insecurity in patients with diabetes was 24.4%, 33.1%, 28.9%, and 13.6%, respectively. There was a significant difference among the food-secure/insecure sex groups (P = 0.001). The prevalence of food insecurity and risk factors such as total cholesterol, high low-density lipoprotein cholesterol, and visceral obesity in mild food-insecure females was significantly higher than males (P < 0.001, 0.001, and 0.001, respectively). The fasting blood sugar significantly increased (P = 0.020) in diabetic females with food security than the other female groups. Diastolic blood pressure significantly increased (P = 0.028) in diabetic females with severe food insecurity than the other female groups. The glycosylated hemoglobin significantly increased (P = 0.013) in diabetic males with severe food insecurity than the other male groups. Food insecurity odds ratio in females was 1.74 (95% confidence interval [CI]: 1.10-2.70), 2.39 (95% CI: 1.48-3.88), and 2.73 (95% CI: 1.49-5.01) times higher than in males for mild, moderate, and severe food insecurity, respectively. Conclusion: Food insecurity may deteriorate some cardiometabolic biomarkers in type 2 diabetes. Improving food security in patients with diabetes may help reduce cardiovascular disease. PMID- 29184578 TI - The Effect of Emotional Intelligence Training on Self-efficacy in Women with Multiple Sclerosis. AB - Background: Multiple sclerosis (MS), a chronic disease of the central nervous system (CNS), causing progressive nerve damage, has disabling symptoms, and undermines self-efficacy beliefs. Due to the importance of self-efficacy modified in adaptation and coping with stress, this study was conducted with the aim to investigate the effect of emotional intelligence training on self-efficacy in women with MS. Materials and Methods: This randomized clinical trial was conducted on 70 women referring to the Multiple Sclerosis Clinic of Kashani Hospital, Isfahan, Iran. The participants were randomly assigned to two groups through minimization method. In the experimental group, emotional intelligence training was performed within 8 weeks, once a week for 90 minutes, in groups of 8 9 individuals. Data were collected using the Multiple Sclerosis Self-efficacy Scale (MSSS) before, immediately after, and 3 months after the intervention in both groups. Data were analyzed using independent t-test and repeated measures ANOVA in SPSS. Results: The results of independent t-test showed no significant difference between the groups in terms of mean self-efficacy scores before the intervention (p > 0.05). However, there was a significant difference between the groups in this regard immediately after and 3 months after the intervention (p < 0.05). Repeated measures ANOVA showed a significant difference in the mean score of self-efficacy and its components between the groups at different times (p < 0.05). Conclusions: It seems that emotional intelligence training is effective on the improvement of self-efficacy of women with MS. Hence, this method can be recommended as an effective and affordable technique. PMID- 29184579 TI - The Impact of Peer Support Program on Adherence to the Treatment Regimen in Patients with Hypertension: A Randomized Clinical Trial Study.

Increase in scores of control group immediately after and 1 month after peer support program was higher (p < 0.001) compared to before the intervention. Conclusions: This study showed that peer support programs had a positive impact on adherence to the treatment regimen in patients suffering from hypertension. PMID- 29184580 TI - The Impact of an Interactive Computer Game on the Quality of Life of Children Undergoing Chemotherapy. AB - Background: Quality of life (QOL) of children with cancer reduces right from the diagnosis of disease and the start of treatment. Computer games in medicine are utilized to interact with patients and to improve their health-related behaviors. This study aimed to investigate the effect of an interactive computer game on the QOL of children undergoing chemotherapy. Materials and Methods: In this clinical trial, 64 children with cancer aged between 8 and12 years were selected through convenience sampling and randomly assigned to experimental or control group. The experimental group played a computer game for 3 hours a week for 4 consecutive weeks and the control group only received routine care. The data collection tool was the Pediatric Quality of Life Inventory (PedsQL) 3.0 Cancer Module Child self report designed for children aged between 8 to 12 years. Data were analyzed using descriptive and inferential statistics in SPSS software. Results: Before intervention, there was no significant difference between the two groups in terms of mean total QOL score (p = 0.87). However, immediately after the intervention (p = 0.02) and 1 month after the intervention (p < 0.001), the overall mean QOL score was significantly higher in the intervention group than the control group. Conclusions: Based on the findings, computer games seem to be effective as a tool in influencing health-related behavior and improving the QOL of children undergoing chemotherapy. Therefore, according to the findings of this study, computer games can be used to improve the QOL of children undergoing chemotherapy. PMID- 29184581 TI - Comparison of the Effect of Topical Application of Rosemary and Menthol for Musculoskeletal Pain in Hemodialysis Patients. AB - Background: Pain is the most common problem experienced by hemodialysis patients, especially musculoskeletal pain in lower extremities, which is usually not completely treated and adversely affects their quality of life. The present study was conducted with the aim to determine and compare the effects of topical application of menthol and rosemary for musculoskeletal pain in hemodialysis patients. Materials and Methods: The present single-blind clinical trial recruited 105 eligible patients undergoing hemodialysis in selected hospitals affiliated to Isfahan University of Medical Sciences; patients were selected by convenient sampling. Participants' severity of pain was determined prior to intervention. They were then randomly divided into rosemary, menthol, and placebo groups. All three groups applied medication on the site of pain on their legs three times a day for three days and recorded the severity of pain four hours after morning and afternoon applications. The statistical analysis of data was performed using SPSS 18. Results: The mean score of severity of pain before the intervention was not significantly different among the three groups (p = 0.83), but it became significantly different after intervention (p = 0.001). Significant differences were observed in mean severity of pain before and after intervention in rosemary and menthol groups (p < 0.001), but not in the placebo group (p = 0.21). Conclusions: Topical application of menthol and rosemary can alleviate severity and frequency of recurrence of musculoskeletal pain in hemodialysis patients; however, according to the results of the study, none had precedence over the other. PMID- 29184582 TI - Challenges of Nurses' Empowerment in the Management of Patient Aggression: A Qualitative Study. AB - Background: Patients' aggression in the mental care setting is a global health problem with major psychological, physical, and economic consequences; nurse empowerment to manage this aggressive behavior is an important step in psychiatric nursing. The aim of this study was to explore psychiatric nurses' experiences of the challenges of empowerment in the management of patients' aggression. Materials and Methods: This qualitative study was performed among 20 nurses working in a major referral psychiatric center in Iran during 2014-2016. The purposive sampling method was used for selecting the participants. Data were collected through semi-structured interviews, observations, and filed notes. Inductive content analysis was used for data analysis. Results: Three categories and ten subcategories were identified: inefficient organizational policy (limited human resources, mandatory shifts, shortage of protective equipment, lack of motivational sparks); insufficient job growth (failure to implement training programs, insufficient effort for job competence, lack of clinical guidelines); and deficiencies in the organizational culture (inadequate autonomy and authority, lack of the culture of prevention, culture of fault and blame after an incident). Conclusions: Psychiatric nurses were not satisfied with organizational empowering conditions for the management of patients' aggression and reported low levels of access to learning opportunity, receiving support and essential resources that led to unnecessary use of containment measures. Managers must make every effort to create organizational context that make it possible to empower nurses for optimal practice. PMID- 29184583 TI - A Qualitative Study on Negative Emotions Triggered by Breastfeeding; Describing the Phenomenon of Breastfeeding/Nursing Aversion and Agitation in Breastfeeding Mothers. AB - Background: Breastfeeding aversion and agitation (BAA) while breastfeeding is anecdotally known to occur in some women who breastfeed while pregnant or those who tandem feed a newborn and a toddler. However, it is a little-researched area and the paucity of published literature around BAA reveals a significant gap in the literature. Materials and Methods: This study presents the findings and responses of 694 women who filled in an anonymous survey questionnaire that collected data on their basic demographics and their experiences with breastfeeding. It uses thematic and inductive content analysis, with qualitative interpretive description to present the findings. Results: The findings of this study shed light on an experienced phenomenon of aversion and agitation whilst breastfeeding, which varies in form, severity, and duration. It is characterised by feelings of anger or rage, a skin crawling sensation and an urge to remove the suckling infant, but can also be feelings of agitation and irritability whilst the infant is latched. A number of mothers who experience aversion still continue to breastfeed, but have feelings of guilt and shame while also experiencing confusion around those feelings. Conclusions: BAA is a phenomenon that occurs in some women who breastfeed, whereby breastfeeding triggers negative emotions. The reason women experience it is not clearly known. Research is needed to understand its cause, triggers, and strategies to minimise the experience in breastfeeding mothers. PMID- 29184584 TI - Evaluating the Effective Factors for Reporting Medical Errors among Midwives Working at Teaching Hospitals Affiliated to Isfahan University of Medical Sciences. AB - Background: Recently, evaluation and accreditation system of hospitals has had a special emphasis on reporting malpractices and sharing errors or lessons learnt from errors, but still due to lack of promotion of systematic approach for solving problems from the same system, this issue has remained unattended. This study was conducted to determine the effective factors for reporting medical errors among midwives. Materials and Methods: This project was a descriptive cross-sectional observational study. Data gathering tools were a standard checklist and two researcher-made questionnaires. Sampling for this study was conducted from all the midwives who worked at teaching hospitals affiliated to Isfahan University of Medical Sciences through census method (convenient) and lasted for 3 months. Data were analyzed using descriptive and inferential statistics through SPSS 16. Results: Results showed that 79.1% of the staff reported errors and the highest rate of errors was in the process of patients' tests. In this study, the mean score of midwives' knowledge about the errors was 79.1 and the mean score of their attitude toward reporting errors was 70.4. There was a direct relation between the score of errors' knowledge and attitude in the midwifery staff and reporting errors. Conclusions: Based on the results of this study about the appropriate knowledge and attitude of midwifery staff regarding errors and action toward reporting them, it is recommended to strengthen the system when it comes to errors and hospitals risks. PMID- 29184585 TI - Do Psychosocial Factors Predict Readmission among Diabetic Elderly Patients? AB - Background: Despite advances in diabetes treatment, the rate of readmission is still relatively high among these patients, especially in older population. Various factors may predict readmission in these patients; hence, the aim of this study was to assess the role of psychosocial factors in predicting readmission among diabetic elderly hospitalized in selected hospitals of Isfahan. Materials and Methods: In this cross-sectional study conducted from January to September 2016, 150 diabetic elderly hospitalized in selected hospitals affiliated with Isfahan University of medical sciences were chosen using a convenient sampling method. The initial information was collected by a three-part questionnaire consisting of (a) demographic characteristics, (b) 21-item depression, anxiety, and stress scale (DASS-21), and (c) multidimensional scale of perceived social support (MSPSS). Further information about readmission was gathered 3 months after completing the questionnaires through a phone call follow-up. Descriptive and inferential statistics (discriminant function analysis test) were used to analyze the data. Results: During 3 months after discharge, 44% of hospitalized diabetic elderly were readmitted. Analytical model predicted the readmission status of 109 individuals (of total 150 persons) in the studied units (success rate of 72.2%). Among predicting factors, depression and social support had the most and the least important roles in predicting readmission rate, respectively. Conclusions: Interventions to improve mental status (i.e., decreasing levels of depression, anxiety, and stress) and develop social support are suggested to reduce the risk of readmission among diabetic elderly patients. Nevertheless, future studies are needed to verify the value of such interventions. PMID- 29184586 TI - Study of the Impact of Educational Behavioral Interventions on Fatigue in Mothers in the Postpartum Period in the Groups of Face-to-Face and Electronic Training. AB - Background: Maternal fatigue in the postpartum period include factors that affect the quality of life and health of both the mother and newborn. This study aimed to investigate two educational approaches regarding mother's fatigue in the postpartum period. Materials and Methods: This experimental study was performed among 110 pregnant mothers during their postpartum care using random sampling. The participants were divided in three groups, namely, face-to-face, e-learning, and control groups. Interventions included individual meetings between the researcher and mothers in the face-to-face group and giving educational compact disc to the e-learning department to improve maternal fatigue. Personal information and fertility data was obtained (before training); the maternal fatigue questionnaire Fatigue Severity Scale (FSS) was completed before and after any type of (face-to-face, e-learning, and control) education. Obtained data were analyzed using one-way analysis of variance (ANOVA) and repeated-measures ANOVA. Results: Results showed that both face-to-face and e-learning methods had similar maternal fatigue scores. The average change on the maternal fatigue score in the second treatment was (p = 0.02) and the third treatment was (p < 0.001)among three groups that was indicative of significant statistical differences. Similarly, there was no statistically significant difference in the average maternal fatigue score between the two groups before the intervention and in the second and third groups after the intervention. Therefore, over time, the training was unaffected. Conclusions: The findings of this study indicate that both face-to-face and e-learning methods are effective to reduce maternal postpartum fatigue. PMID- 29184587 TI - Assessment of the Relationship between Spiritual and Social Health and the Self Care Ability of Elderly People Referred to Community Health Centers. AB - Background: Promotion of self-care ability among older people is an essential means to help maintain and improve their health. However, the role of spiritual and social health has not yet been considered in detail in the context of self care ability among elderly. The aim of this study was to assess the relationship between spiritual and social health and self-care ability of older people referred to community health centers in Isfahan. Materials and Methods: In this cross-sectional correlation study, 200 people, aged 60 years and older, referred to healthcare centers in 2016 were recruited through convenience sampling method. Data were collected by four-part tool comprising of: (a) demographics, (b) Ellison and Palotzin's spiritual well-being scale, (c) Kees's "social health" scale, and (d) self-care ability scale for the elderly by Soderhamn's; data were analyzed by descriptive and inferential (independent t-test, analysis of variance - ANOVA, Pearson's coefficient tests, and multiple regression analysis) statistics by SPSS16 software. Results: Findings showed that the entered predictor variables were accounted for 41% of total variance (R2 ) of the two self-care ability in the model (p < 0.001, F3, 199 = 46.02). Two out of the three predictor variables including religious well-being and social health, significantly predicted the self-care ability of older people. Conclusions: The results of this study emphasized on the relationship between spiritual and social health of the elderly people and their ability to self-care. Therefore, it would be recommended to keep the focus of the service resources towards improving social and spiritual health to improve self-care ability in elderly people. PMID- 29184588 TI - Clinical Outcomes of High-Risk Infant Follow-Up Program in a Tertiary Care Centre. AB - Background: High-risk infant follow-up (HRIF) program is necessary for early detection, timely intervention, and promotion of health outcomes in vulnerable infants, ethically. The present study was carried out to assess the clinical outcomes of the HRIF Program in Alzahra hospital as a tertiary care centre, in Iran. Materials and Methods: In this cohort study, 5840 neonates were born at Alzahra hospital, from June 1, 2011 to 30th February 2012. Among those who were admitted to neonatal intensive care unit (NICU), 253 infants were recruited by census according to HRIs criteria. After doing necessary measurements and family education, information was recorded in HRI health certificate and then entered in the access database for analysis. Results: From 253 eligible HRIs registered, 241 (95%) infants attended the follow-up clinic after discharge. A total of180 cases were recalled for further visits, 110 of which attended the clinic. Anthropometric indices had an increasing trend in the first 6 months of life. There was no significant relation between ages and stages questionnaire (ASQ) results and infant birth weight, height, and head circumference. The ratios of intraventricular hemorrhage (IVH) and retinopathy of prematurity (ROP) were 8.7% and 3.1%, respectively. The incidence of congenital hypothyroidism was 2:341 in HRIs. Conclusions: Although some outcomes, such as ROP, improved in our study compared to similar studies, the findings indicate an impairment of the current follow-up processes and highlight the necessity to modify the current HRIF program. Ethically, we insist on integrating HRIF program in child health services to promote early childhood development. PMID- 29184589 TI - Comparing the Effect of Echinacea and Chlorhexidine Mouthwash on the Microbial Flora of Intubated Patients Admitted to the Intensive Care Unit. AB - Background: Providing intubated patients admitted to the intensive care units with oral healthcare is one of the main tasks of nurses in order to prevent Ventilator-Associated Pneumonia (VAP). This study aimed at comparing the effects of two mouthwash solutions (echinacea and chlorhexidine) on the oral microbial flora of patients hospitalized in the intensive care units. Materials and Methods: In this clinical trial, 70 patients aged between18 and 65 years undergoing tracheal intubation through the mouth in three hospitals in Arak, were selected using simple random sampling and were randomly divided into two groups: the intervention group and the control group. The oral health checklist was used to collect the data (before and after the intervention). The samples were obtained from the orally intubated patients and were then cultured in selective media. Afterwards, the aerobic microbial growth was investigated in all culture media. The data were analyzed using SPSS software. Results: The microbial flora in the echinacea group significantly decreased after the intervention (p < 0.0001) and it was also the case withmicrobial flora of the patients in the chlorhexidine group (p < 0.001). After 4 days, the oral microbial flora of the patients in the intervention group was lower than that of the patients in the control group (p < 0.001). Conclusions: The results showed that the echinacea solution was more effective in decreasing the oral microbial flora of patients in the intensive care unit. Given the benefits of the components of the herb Echinacea, it can be suggested as a viable alternative to chlorhexidine. PMID- 29184590 TI - The Impact of an Educational Program Regarding Total Parenteral Nutrition on Infection Indicators in Neonates Admitted to the Neonatal Intensive Care Unit. AB - Background: One of the basic care measures for preterm infants is providing nutrition through total parenteral nutrition (TPN) and one of the most important complications of it is infection. Because prevention of nosocomial infections is an important issue for neonate's safety, this study aimed to determine the effects of a continuing medical education (CME) course on TPN for neonatal intensive care unit (NICU) nurses on indicators of infection in newborns. Materials and Methods: This quasi-experimental study was conducted on 127 neonates who fulfilled the inclusion criteria. They were selected through simple convenience sampling method at two stages of before and after the CME program. The inclusion criteria were prescription of TPN by the physician and lack of clinical evidences for infection in newborns before the beginning of TPN. Death of the infant during each stage of the study was considered as the exclusion criteria. The data gathering tool was a data record sheet including clinical signs of infection in the infants and their demographic characteristics. Data were analyzed using Chi-square test, Fisher's exact test, and student's t-test in SPSS software. Results: The results showed the frequency of clinical markers for infection in newborns at the pre-intervention stage (n = 41; 65.10%) was significantly less than at the post-intervention stage (n = 30; 46.90%) (p = 0.04). Conclusions: Nursing educational programs on TPN reduce infection rates among neonates in NICUs. PMID- 29184591 TI - Iranian Pediatric Nurse's Experience: The Facilitators of the Learning of Ethical Practices. AB - Background: Ethical care is a core value in nursing. Pediatric nurses are in direct and continuous contact with children and their parents. They manage their lives and health. As part of the pediatric nurses' daily work, ethical issues play an important role in making decisions, are important to make decisions, and this capability is only achieved by ethical practice. This study aimed to explore the factors facilitating the learning of ethical practice among Iranian pediatric nurses. Materials and Methods: This study is a conventional qualitative content analysis based on the Graneheim and Lundman method. It was conducted through semi structured interviews with two focus groups, incorporating 28 nurses working in pediatric wards. Unstructured observation and field notes were other methods of data collection. Purposive sampling continued until data saturation was ensured. All interviews were tape recorded and transcribed in verbatim. Results: Three main categories and 12 subcategories emerged from this study. The facilitating factors include (1) individual competencies (knowledge, experience, emotional intelligence, and loving children), (2) ethical imprinting (responsibility, reflection, empathy, and ethical beliefs), and (3) an environment that nurtures moral values (organizational, spiritual, family, and cultural environments) as facilitating factors. Conclusions: The promotion of nurses' competencies, ethical virtues, and imprinting, as well as improvement of the quality of nursing care must be the top priority of the health team. Undoubtedly, the success of the health care system is not possible without ensuring that pediatric nurses learn ethical practices.

PMID- 29184593 TI - Cognitive impairment in COPD: should cognitive evaluation be part of respiratory assessment? AB - : Cognitive impairment is highly prevalent in patients with COPD and demonstrates multiple detrimental effects on many aspects of patient state and therapeutic outcomes. It is attributed to several overlapping pathophysiological factors, with the most common being the low level of oxygen saturation due to respiratory insufficiency. Despite the impact of cognitive impairment on clinical outcomes, the screening for coexisting cognitive deficits which may interfere with the successful progress of respiratory treatment is yet neglected. There is a special consideration that cognitive deficits should be taken into account when developing respiratory therapy plans. Cognitively impaired patients are likely to require more support and have need of an individualised respiratory care plan which can also be beneficial for their cognitive deficits. Pulmonary rehabilitation as a multidisciplinary approach could be prioritised for COPD patients with cognitive impairment. Educational aims: To illustrate the common signs of cognitive impairment and define potential associations between lung and cognitive dysfunction.To illustrate the potential influence of cognitive deficits on the optimal progress of respiratory therapy.To illustrate the importance of cognitive evaluation as part of a comprehensive clinical assessment for patients suspected of suffering cognitive impairment.

PMID- 29184596 TI - The use of tracheal sounds for the diagnosis of sleep apnoea. AB - : Tracheal sounds have been the subject of many research studies. In this review, we describe the state of the art, original work relevant to upper airways obstruction during sleep, and ongoing research concerning the methods used when analysing tracheal sounds. Tracheal sound sensors are a simple and noninvasive means of measurement and are more reliable than other breathing sensors. Developments in acoustic processing techniques and enhancements in tracheal sound signals over the past decade have led to improvements in the accuracy and clinical relevance of diagnoses based on this technology. Past and current research suggests that they may have a significant role in the diagnosis of obstructive sleep apnoea. Key points: Tracheal sounds are currently a topic of significant interest but are not yet used in most routine sleep study systems.Measured at the suprasternal notch, tracheal sounds can provide reliable information on breathing sounds, snoring sounds and respiratory efforts.Tracheal sounds may be used as a noninvasive method of studying abnormalities of the upper airways during wakefulness. Educational aims: To understand the principles of tracheal sound measurement and analysis.To highlight the importance of tracheal sounds for the diagnosis of sleep apnoea-hypopnoea syndrome.To present the most relevant clinical studies that have validated the use of tracheal sound sensors and to make future clinical validation studies possible. PMID- 29184597 TI - The impact and cost-effectiveness of the Amref Health Africa-Smile Train Cleft Lip and Palate Surgical Repair Programme in Eastern and Central Africa. AB - Introduction: Cleft lip with or without cleft palate (CLP) is a congenital malformation that causes significant morbidity in low and middle income countries. Amref Health Africa has partnered with Smile Train to provide CLP surgeries since 2006. Methods: We analyzed anonymized data of 37,274 CLP patients from the Smile Train database operated on in eastern and central Africa between 2006 and 2014. Cases were analyzed by age, gender, country and surgery type. The impact of cleft surgery was determined by measuring averted Disability-Adjusted Life Years (DALYs) and delayed averted DALYs. We used mean Smile Train costs to calculate cost-effectiveness. We calculated economic benefit using the human capital approach and Value of Statistical Life (VSL) methods. Results: The median age at time of primary surgery was 5.4 years. A total of 207,879 DALYs were averted at a total estimated cost of US$13 million. Mean averted DALYs per patient were 5.6, and mean cost per averted DALY was $62.8. Total delayed burden of disease from late age at surgery was 36,352 DALYs. Surgical correction resulted in $292 million in economic gain using the human capital approach and $2.4 billion using VSL methods. Conclusion: Cleft surgery is a cost-effective intervention to reduce disability and increase economic productivity in eastern and central Africa. Dedicated programs that provide essential CLP surgery can produce substantial clinical and economic benefits. PMID- 29184598 TI - [Exophytic tumor of the scalp]. AB - Proliferating trichilemmal tumor (PTT), still referred to as proliferative trichilemmal cyst (TC), is an uncommon malignant adnexal tumor originating from the cells of the outer root sheath of the hair follicle or, more often, from a trichilemmal cyst, following multiple trauma and/or recurrent inflammation. We report the case of a 64-year old female patient, with no particular previous history, presenting with tumor of the scalp gradually evolving over 18 months. Clinical examination showed a painless, firm, adhering ulcero-budding tumor mass measuring 12 cm along its longer axis at the level of the vertex. The patient had clinically negative lymph nodes. Histological examination showed malpighian cell proliferation arranged in clumps and coalescing lobules with focal areas of abrupt trichilemmal keratinization, with very marked atypies cyto-nuclear and an infiltrated fibrous stroma, suggesting proliferating trichilemmal tumor. Staging evaluation showed no metastase. The patient underwent wide surgical resection followed by in depth removal of extra tissue, without recurrence at 3-months' follow-up. PMID- 29184599 TI - [Lipoma of the deep lobe of the parotid gland]. AB - Lipomas of the parotid gland are benign tumors developing from the fatty tissue in the gland. They are rare, accounting for 0.6-4.4% of all benign tumors. Those located in the deep lobe of the gland are uncommon. Clinically, they are very difficult to diagnose. CT scan and especially MRI can support the diagnosis. Surgery is the treatment of choice but its modalities remain controversial. We report the case of a 52-year old female patient, with no particular past medical history, presenting with asymptomatic left preauricular mass evolving over 1 year and gradually increasing in volume. Clinical examination showed painless elastic swelling, measuring 2 * 1.5 * 1 cm, extending from the ear lobule to the left mandibular angle. Stensen duct wasn't obstructed and saliva was clear. The patient showed no facial paralysis. CT scan showed perfectly delimited unilobular hypodense homogeneous mass in the deep lobe of the parotid gland. No suspected cervical lymphadenopathy was detected. MRI confirmed the presence of homogeneous, lipomatous intraparotid tissue process. After superficial parotidectomy and translocation of the branches of the facial nerve, a yellowish mass appeared under the buccal and mandibular branches of the facial nerve. The patient underwent complete resection up to the left parapharyngeal space. The postoperative course was uneventful. Anatomo-pathological examination confirmed the diagnosis of lipoma of the deep lobe of the parotid gland.

It is a constitutional deficit of humoral immunity characterized by recurrent bacterial infections and by increased frequency of tumors, autoimmune or granulomatous diseases. Gastrointestinal manifestations are very variable and sometimes reveal common variable immune deficiency. We report the case of a 31-year old patient with a history of childhood recurrent respiratory infections complicated by bronchiectasis and with a 3-year history of recurrent glairy diarrhea. Etiological balance was in favor of CVID with autoimmune manifestation (vitiligo). Patient's treatment was based on monthly immunoglobulin (Ig) infusions with favorable outcome at 2-year follow-up. PMID- 29184601 TI - Obesity as a form of malnutrition: over-nutrition on the Uganda "malnutrition" agenda. AB - : The objectives were to highlight the burden of overweight and obesity as an additional area of importance for the malnutrition agenda in Uganda and to provide evidence-based considerations for stakeholders involved. INTRODUCTION: Mirroring other Low- and Middle-Income Countries (LMICs), Uganda is experiencing a "double burden" of over-nutrition related issues - both obesity and overweight, and related non-communicable diseases (NCDs) alongside the under-nutrition that has long plagued the country. Despite the commonplace assumption that under nutrition is the predominant form of malnutrition in Uganda, we explore recent literature that in fact, challenges this notion. While food insecurity has contributed to the under-nutrition problem, a lack of dietary diversity also has a demonstrated role in increasing over-nutrition. We cannot afford to ignore over nutrition concomitant with stunting and wasting in the country. Increase in the burden of this less acknowledged form of malnutrition in Uganda is critical to investigate, and yet poorly understood. A move towards increased regionally targeted over-nutrition research, funding, government prioritization and advocacy is needed.

AB - Bladder exstrophy is a malformation characterized by subumbilical anterior abdominal wall and anterior bladder wall deishence. It affects nearly 30.000 40.000 births per year, with a higher prevalence in boys. External continent urinary diversion creates a long-term outcome. However, it is not devoid of complications. We report the case of a 30-year old female patient who had undergone cystectomy with bladder replaced with ileo-caecal segment for bladder exstrophy 13 years earlier. She was followed up for 5 years and then lost to follow up. In March 2017 she presented with painful abdominal heaviness as well as constipation evolving in a context of apyrexy and good general condition. Clinical examination showed good general health, midline laparotomy scar, continent uninvaginated urinary pouch valve. Pelvic examination was unremarkable. Hypogastric palpation showed nonpainful stony-hard mass. Urinary tract without preparation showed calcic opacity 130*110 mm as well as symphysis disjunction. Renal and pelvic ultrasound showed several hyperechogen images with posterior shadow cone occupying the pelvis, two well differentiated kidneys of normal size without ureteric hydronephrosis. CT urography showed 5 big calcium stones with an average density of 730 UH, the most voluminous of which measured 112*101 mm, in the neobladder. Renal function was normal and cytobacteriological examination of urine showed ESBL-producing E coli urinary tract infection sensitive to carbapenems. Treatment was based on suitable antibiotic therapy associated with entero-cystolithotomy involving laborious extraction of 5 big stones. Spectrophotometric examination revealed phospho-ammonium-magnesium stones. The postoperative course was uneventful, post operative urinary tract without preparation showed no stones.

PMID- 29184605 TI - The risk of ischemic optic neuropathy post phacoemulsification cataract surgery. AB - Introduction: The aim was to study the risk of non arteritic ischemic optic neuropathy after phacoemulsification cataract surgery. Methods: This study was conducted at King Hussein Medical Center during the period between January 2015 and July 2016. Patients attending ophthalmology clinic complaining of decreased vision due to lens opacity were evaluated. Patients were divided into two groups. First group included patients with no medical illness and second group included patients with diabetes mellitus, hypertension or hyperlipidemia. The two groups were further divided into two subgroups. First subgroup included patients who had phacoemulsification surgery and second subgroup did not have surgery. All patients were followed up for 6 months. They were assessed by neuro ophthalmologist looking for ischemic optic neuropathy. Results: A total number of 568 patients were enrolled. Group 1A included patients with no medical illness who underwent surgery and group 1B did not undergo surgery. The number of patients in these two subgroups was 119 and 103 respectively. Number of patients in group 2A (medical illness and surgery) was 188 and number of patients in group 2B (medical illness and no surgery) was 130. The incidence of ischemic optic neuropathy was 4.3 % in group 2A, 4.2 % in group 1A, 0.8% in group 2B, and 0% in group 1B. Conclusion: Phacoemulsification is a risk factor for non arteritic ischemic optic neuropathy independent of the presence of medical risk factors. Suggested mechanisms would be local anaesthesia, intraocular pressure fluctuation and local intraocular inflammation. PMID- 29184606 TI - Knowledge, attitude and practice of hygiene and sanitation in a Burundian refugee camp: implications for control of a Salmonella typhi outbreak. AB - Introduction: A Salmonella typhi outbreak was reported in a Burundian refugee camp in Rwanda in October 2015. Transmission persisted despite increased hygiene promotion activities and hand-washing facilities instituted to prevent and control the outbreak. A knowledge, attitude and practice (KAP) study was carried out to assess the effectiveness of ongoing typhoid fever preventive interventions. Methods: A cross-sectional survey was conducted in Mahama Refugee Camp of Kirehe District, Rwanda from January to February 2016. Data were obtained through administration of a structured KAP questionnaire. Descriptive, bivariate and multivariate analysis was performed using STATA software. Results: A total of 671 respondents comprising 264 (39.3%) males and 407 (60.7%) females were enrolled in the study. A comparison of hand washing practices before and after institution of prevention and control measures showed a 37% increase in the proportion of respondents who washed their hands before eating and after using the toilet (p < 0.001). About 52.8% of participants reported having heard about typhoid fever, however 25.9% had received health education. Only 34.6% and 38.6% of the respondents respectively knew how typhoid fever spreads and is prevented. Most respondents (98.2%) used pit latrines for disposal of feces. Long duration of stay in the camp, age over 35 years and being unemployed were statistically associated with poor hand washing practices. Conclusion: The findings of this study underline the need for bolstering up health education and hygiene promotion activities in Mahama and other refugee camp settings.

AB - Macular coloboma is a congenital condition characterized by failure of closure of the fetal intraocular fissure which may have a hereditary origin. Clinically, it is characterized by decreased visual acuity with macular excavated lesion characterized by missing or rudimentary retinal tissue and scleral ectasia. Macular OCT strongly supports the diagnosis and electrophysiology examination, if requested, is altered. Differential diagnosis includes pathologies causing atrophic and excavated macular lesion, in particular congenital toxoplasmosis. PMID- 29184610 TI - Colonoscopy procedural volume increases adenoma and polyp detection rates in gastroenterologytrainees. AB - AIM: To investigate changes in polyp detection throughout fellowship training, and estimate colonoscopy volume required to achieve the adenoma detection rate (ADRs) and polyp detection rate (PDRs) of attending gastroenterologists. METHODS: We reviewed colonoscopies from July 1, 2009 to June 30, 2014. Fellows' procedural logs were used to retrieve colonoscopy procedural volumes, and these were treated as the time variable. Findings from screening colonoscopies were used to calculate colonoscopy outcomes for each fellow for the prior 50 colonoscopies at each time point. ADR and PDR were plotted against colonoscopy procedural volumes to produce individual longitudinal graphs. Repeated measures linear mixed effects models were used to study the change of ADR and PDR with increasing procedural volume. RESULTS: During the study period, 12 fellows completed full three years of training and were included in the analysis. The average ADR and PDR were, respectively, 31.5% and 41.9% for all fellows, and 28.9% and 38.2% for attendings alone. There was a statistically significant increase in ADR with increasing procedural volume (1.8%/100 colonoscopies, P = 0.002). Similarly, PDR increased 2.8%/100 colonoscopies (P = 0.0001), while there was no significant change in advanced ADR (0.04%/100 colonoscopies, P = 0.92). The ADR increase was limited to the right side of the colon, while the PDR increased in both the right and left colon. The adenoma per colon and polyp per colon also increased throughout training. Fellows reached the attendings' ADR and PDR after 265 and 292 colonoscopies, respectively. CONCLUSION: We found that the ADR and PDR increase with increasing colonoscopy volume throughout fellowship. Our findings support recent recommendations of >= 275 colonoscopies for colonoscopy credentialing. PMID- 29184609 TI - Liver atrophy after percutaneous transhepatic portal embolization occurs in two histological phases: Hepatocellular atrophy followed by apoptosis. AB - AIM: To clarify the histological changes associated with liver atrophy after percutaneous transhepatic portal embolization (PTPE) in pigs and humans. METHODS: As a preliminary study, we performed pathological examinations of liver specimens from five pigs that had undergone PTPE in a time-dependent model of liver atrophy. In specimens from embolized lobes (EMB) and nonembolized lobes (controls), we measured the portal vein to central vein distance (PV-CV), the area and number of hepatocytes per lobule, and apoptotic activity using the terminal deoxynucleotidyl transferase dUTP nick-end labeling assay. Immunohistochemical reactivities were evaluated for light chain 3 (LC3) and lysosomal-associated membrane protein 2 (LAMP2) as autophagy markers and for glutamine synthetase and cytochrome P450 2E1 (CYP2E1) as metabolic zonation markers. Samples from ten human livers taken 20-36 d after PTPE were similarly examined. RESULTS: PV-CVs and lobule areas did not differ between EMB and controls at day 0, but were lower in EMB than in controls at weeks 2, 4, and 6 (P <= 0.001). Hepatocyte numbers were not significantly reduced in EMB at day 0 and week 2 but were reduced at weeks 4 and 6 (P <= 0.05). Apoptotic activity was higher in EMB than in controls at day 0 and week 4. LC3 and LAMP2 staining peaked in EMB at week 2, with no significant difference between EMB and controls at weeks 4 and 6. Glutamine synthetase and CYP2E1 zonation in EMB at weeks 2, 4, and 6 were narrower than those in controls. Human results were consistent with those of porcine specimens. CONCLUSION: The mechanism of liver atrophy after PTPE has two histological phases: Hepatocellular atrophy is likely caused by autophagy in the first 2 wk and apoptosis thereafter. PMID- 29184608 TI - Role of pregnane X-receptor in regulating bacterial translocation in chronic liver diseases. AB - Bacterial translocation (BT) has been impeccably implicated as a driving factor in the pathogenesis of a spectrum of chronic liver diseases (CLD). Scientific evidence accumulated over the last four decades has implied that the disease pathologies in CLD and BT are connected as a loop in the gut-liver axis and exacerbate each other. Pregnane X receptor (PXR) is a ligand-activated transcription factor and nuclear receptor that is expressed ubiquitously along the gut-liver-axis. PXR has been intricately associated with the regulation of various mechanisms attributed in causing BT. The importance of PXR as the mechanistic linker molecule in the gut-liver axis and its role in regulating bacterial interactions with the host in CLD has not been explored. PubMed was used to perform an extensive literature search using the keywords PXR and bacterial translocation, PXR and chronic liver disease including cirrhosis. In an adequate expression state, PXR acts as a sensor for bile acid dysregulation and bacterial derived metabolites, and in response shapes the immune profile beneficial to the host. Activation of PXR could be therapeutic in CLD as it counter-regulates endotoxin mediated inflammation and maintains the integrity of intestinal epithelium. This review mainly focuses PXR function and its regulation in BT in the context of chronic liver diseases. PMID- 29184612 TI - Efficacy of Prucalopride in bowel cleansing before colonoscopy: Results of a pilot study. AB - Colonoscopy is a crucial diagnostic instrument for colorectal cancer screening and an adequate bowel preparation is definitely decisive for the success of the procedure. Especially in elderly patients, bowel cleansing is considered a big issue, because it is often poorly tolerated for many reasons (like inability to swallow large volume of liquids or unlikable taste); this can cause a suboptimal preparation that may lead to miss a neoplastic lesion. There is relatively little data about how to improve preparation tolerability. The purpose of our pilot study was to analyze the effect of prucalopride (Resolor(r)), a highly selective serotonin 5HT4 receptor agonist used for chronic constipation for its ability to stimulate gastrointestinal peristalsis, undertaken the day before colonoscopy, followed by half volume of polyethylene glycol solution. We found that this can be a good and safe method to achieve an adequate and better-tolerated colon cleansing. PMID- 29184611 TI - Safety of gastrointestinal endoscopy with conscious sedation in obstructive sleep apnea. AB - AIM: To perform a systematic review and meta-analysis to assess the safety of conscious sedation in patients with obstructive sleep apnea (OSA). METHODS: A comprehensive electronic search of MEDLINE and EMBASE was performed from inception until March 1, 2015. In an effort to include unpublished data, abstracts from prior gastroenterological society meetings as well as other reference sources were interrogated. After study selection, two authors utilizing a standardized data extraction form collected the data independently. Any disagreements between authors were resolved by consensus among four authors. The methodological quality was assessed using the Newcastle Ottawa tool for observational studies. The primary variables of interest included incidence of hypoxia, hypotension, tachycardia, and bradycardia. Continuous data were summarized as odds ratio (OR) and 95%CI and pooled using generic inverse variance under the random-effects model. Heterogeneity between pooled studies was assessed using the I2 statistic. RESULTS: Initial search of MEDLINE and EMBASE identified 357 citations. A search of meeting abstracts did not yield any relevant citations. After systematic review and exclusion consensus meetings, seven studies met the a priori determined inclusion criteria. The overall methodological quality of included studies ranged from moderate to low. No significant differences between OSA patients and controls were identified among any of the study variables: Incidence of hypoxia (7 studies, 3005 patients; OR = 1.11; 95%CI: 0.73-1.11; P = 0.47; I2 = 0%), incidence of hypotension (4 studies, 2125 patients; OR = 1.10; 95%CI: 0.75-1.60; P = 0.63; I2 = 0%), incidence of tachycardia (3 studies, 2030 patients; OR = 0.94; 95%CI: 0.53-1.65; P = 0.28; I2 = 21%), and incidence of bradycardia (3 studies, 2030 patients; OR = 0.88; 95%CI: 0.63-1.22; P = 0.59; I2 = 0%). CONCLUSION: OSA is not a significant risk factor for cardiopulmonary complications in patients undergoing endoscopic procedures with conscious sedation. PMID- 29184613 TI - Gender Differences among Patients with Acute Coronary Syndrome in the Middle East. AB - Background: There is controversy regarding the relationship between gender and acute coronary syndrome (ACS). Objective: To study the impact of gender on presentation, management, and mortality among patients with ACS in the Middle East. Methodology: From January 2012 to January 2013, 4057 patients with ACS were enrolled from four Arabian Gulf countries (Kuwait, Oman, United Arab Emirates, and Qatar), representing more than 85% of the general hospitals in each of the participating countries. Results: Compared to men, women were older and had more comorbidities. They also had atypical presentation of ACS such as atypical chest pain and heart failure. The prevalence of non-ST-segment elevation myocardial infarction (49 vs. 46%; P < 0.001) and unstable angina (34 vs. 24%; P < 0.001) was higher among women as compared to men. In addition, women were less likely to receive evidence-based medications such as aspirin, clopidogrel, beta-blocker, and angiotensin-converting enzyme inhibitors on admission and on discharge. During hospital stay, women suffered more heart failure (15 vs. 12%; P = 0.008) and were more likely to receive blood transfusion (6 vs. 3%; P < 0.001). Women had higher 1-year mortality (14 vs. 11%; P < 0.001), the apparent difference that disappeared after adjusting for age and other comorbidities. Conclusion: Although there were differences between men and women in presentation, management, and in hospital outcomes, gender was shown to be a nonsignificant contributor to mortality after adjusting for confounders. PMID- 29184614 TI - Idiopathic Fascicular Left Ventricular Tachycardia.

PMID- 29184616 TI - Hybrid Completion of Aortic Repair after Type A Aortic Dissection in a Patient with Marfan's Syndrome. AB - Medicine and engineering are in collaboration to assist in the tackling of daunting surgical techniques which are associated with high rates of morbidity and mortality, in exchange for minimally invasive approaches with lower procedural risk. Endovascular procedures in general have already reduced the risk of surgery by limiting the extent of open surgery and often replacing it with purely percutaneous or hybrid procedures. Here, we describe a patient who had complex staged surgery with open repair of a proximal portion of a type A aortic dissection followed by a staged endovascular reconstruction of the arch and descending aorta by means of a fenestrated stent-graft to secure the left subclavian artery and the posterior cerebral circulation. PMID- 29184615 TI - Mobitz Type II Atrioventricular Block following Tramadol and Fentanyl in a Patient with Acute Coronary Syndrome and Systolic Heart Failure. AB - Serotonin syndrome is a potentially fatal condition allied with increased serotonergic activity in the central nervous system. There are published data reporting serotonin syndrome induced by either tramadol or fentanyl in combination with selective serotonin reuptake inhibitors in adult patients; however, there are no reports of serotonin syndrome resulting from the combination of tramadol and fentanyl. We report a case of a 52-year-old woman who was admitted to cardiology service and who developed Mobitz Type II atrioventricular (AV) block after administration of oral tramadol and intravenous fentanyl. PMID- 29184617 TI - Acute Atrial Fibrillation Complicating Organophosphorus Poisoning. AB - Organophosphorus (OP) pesticide poisoning is a major clinical and public health problem in a developing country like India. Cardiac injury is a strong predictor of death in these patients. Cardiac complications usually described include cardiac arrest, pulmonary edema, and arrhythmia. Rarely, myocardial infarction has also been reported. The possible mechanisms for myocardial injury include sympathetic/parasympathetic overactivity, hypoxemia, acidosis, dyselectrolytemia, and direct cardiotoxicity. We describe herein one case of OP poisoning, recently admitted in our emergency department and which was complicated by acute onset atrial fibrillation which reverted to sinus rhythm following detoxification of OP compound. PMID- 29184618 TI - Off-pump Coronary Artery Bypass Surgery in a Patient with Dextrocardia and Situs Inversus: Anesthetic, Surgical Consideration and Role of Transesophageal Echocardiography. AB - Coronary artery bypass surgery (CABG) in dextrocardia with situs inversus patients is reported less in literature. Due to abnormal looping and associated other congenital anomalies, anesthetic implications and surgical difficulties become challenging in these patients. Transesophageal echocardiography examination (TEE) needs multiplane angle adjustments compared to normal heart to obtain the images. Here, we describe a 53-year-old female patient having dextrocardia with situs inversus who underwent CABG and discuss the perioperative management and multiplane adjustments during TEE examination.

AB - Extracellular vesicles (EVs) are membrane particles secreted from cells into all body fluids. Several EV populations exist differing in size and cellular origin. Using differential centrifugation EVs pelleting at 14,000 g ("microvesicles" (MV)) and 100,000 g ("exosomes") are distinguishable by protein markers. Neutral sphingomyelinase (nSMase) inhibition has been shown to inhibit exosome release from cells and has since been used to study their functional implications. How nSMases (also known as SMPD2 and SMPD3) affect the basal secretion of MVs is unclear. Here we investigated how SMPD2/3 impact both EV populations. SMPD2/3 inhibition by GW4869 or RNAi decreases secretion of exosomes, but also increases secretion of MVs from the plasma membrane. Both populations differ significantly in metabolite composition and Wnt proteins are specifically loaded onto MVs under these conditions. Taken together, our data reveal a novel regulatory function of SMPD2/3 in vesicle budding from the plasma membrane and clearly suggest that - despite the different vesicle biogenesis - the routes of vesicular export are adaptable. PMID- 29184624 TI - Is your article EV-TRACKed? AB - The EV-TRACK knowledgebase is developed to cope with the need for transparency and rigour to increase reproducibility and facilitate standardization of extracellular vesicle (EV) research. The knowledgebase includes a checklist for authors and editors intended to improve the transparency of methodological aspects of EV experiments, allows queries and meta-analysis of EV experiments and keeps track of the current state of the art. Widespread implementation by the EV research community is key to its success. PMID- 29184625 TI - Confounding factors in vesicle uptake studies using fluorescent lipophilic membrane dyes. AB - Small extracellular vesicles (sEVs) such as exosomes are nanocarriers of proteins, RNAs and DNAs. Isolation of pure sEV populations remains challenging, with reports of protein and lipoprotein contaminants in the isolates. Cellular uptake - a cornerstone for understanding exosome and sEV function - is frequently examined using lipophilic dyes such as PKH67 or CellMask to label the vesicles. In this study, we investigated whether contaminants can confound the outcomes from sEV and exosomes uptake experiments. sEVs were isolated from blood plasma of fasted or non-fasted rats as well as from serum-supplemented or serum-free conditioned cell culture medium using size-exclusion chromatography (SEC). Eluent fractions were characterized using nanoparticle tracking, protein and triglyceride assays and immunoassays. SEC fractions were labelled with different lipophilic dyes and cellular uptake was quantified using endothelial cells or primary cardiomyocytes. We report co-isolation of sEVs with apolipoprotein B containing lipoproteins. Cellular dye transfer did not correspond to sEV content of the SEC fractions, but was severely affected by lipoprotein and protein content. Overnight fasting of rats decreased lipoprotein content and also decreased dye transfer, while late, sEV-poor/protein-rich fractions demonstrated even greater dye transfer. The potential for dye transfer to occur in the complete absence of sEVs was clearly shown by experiments using staining of sEV depleted serum or pure protein sample. In conclusion, proteins and lipoproteins can make a substantial contribution to transfer of lipophilic dyes to recipient cells. Considering the likelihood of contamination of sEV and exosome isolates, lipophilic dye staining experiments should be carefully controlled, and conclusions interpreted with caution.

PMID- 29184627 TI - Medical sequencing of de novo ectodermal dysplasia in identical twins and evaluation of the potential eligibility for recombinant EDA therapy. AB - The purpose of this study was to test two 8-year-old identical twins with ectodermal dysplasia (ED) and their unaffected parents for the presence of mutations in the EDA gene with the hypothesis that they might be carrying a de novo mutation in EDA and potentially eligible for recombinant EDA therapy. DNA was extracted using saliva samples obtained from the identical twin girls and both parents. PCR products of Ectodyplasin A (EDA), Ectodysplasin Receptor (EDAR), Ectodysplasin Receptor Associated Death Domain (EDARADD), and Connexin-30 (GJB6) were sequenced by the Sanger method and the results analyzed using a reference sequence. Exons and exon-intron boundaries of EDA, EDAR, EDARADD, and GJB6 were sequenced in both parents and the affected identical twin pair. No mutations were detected in EDA or GJB6. Genetic variants located in the intron of EDAR were found but determined to be non-contributory to the twins' ED. A microsatellite polymorphism was detected in all four subjects in exon 4 of the EDARADD gene but determined not to be causal to the ED. There was a silent mutation detected in exon 6 of the EDARADD gene of both the daughters and their unaffected mother but also unlikely to be the cause of ED. These results suggest that ED of the subjects is caused by a de novo mutation in a gene not studied here. It is likely these subjects and their future offspring would not benefit from the development of recombinant EDA replacement therapy. PMID- 29184628 TI - Comparison of in vitro properties of periodontal ligament stem cells derived from permanent and deciduous teeth. AB - Background. Stem cells have contributed to the development of tissue-engineered based regenerative periodontal therapies. In order to find the best stem cell sources for such therapies, the biologic properties of stem cells isolated from periodontal ligaments (PDL) of deciduous (DePDLSC) and permanent (PePDLSC) teeth were comparatively evaluated. Methods. PDL stem cells were isolated from six sound fully erupted premolars and six deciduous canines of healthy subjects. In vitro biologic characteristics such as colony formation, viability, stem cell marker identification and osteogenic differentiation (using alkaline phosphatase analysis and Alizarin red staining) were comparatively assessed using one-way ANOVA and post hoc Tukey tests using SPSS 13.0. Results. Stem cell populations isolated from both groups were CD105+ and CD90+ and CD45-. No statistically significant differences were found in stem cell markers, colony formation and viability. Both groups were capable of osteogenic differentiation. However, alkaline phosphatase activity test showed a statistically significant difference, with PePDLSC exhibiting higher alkaline phosphatase activity (P=0.000). No statistically significant difference was seen in quantitative alizarine red staining (P=0.559). Conclusion. Mesenchymal stem cells of PDL could successfully be isolated from permanent and deciduous teeth. A minor difference was observed in the osteogenic properties of the two cell types, which might affect their future clinical applications. PMID- 29184629 TI - Stress distribution pattern of screw-retained restorations with segmented vs. non segmented abutments: A finite element analysis. AB - Background. Screw-retained restorations are favored in some clinical situations such as limited inter-occlusal spaces. This study was designed to compare stresses developed in the peri-implant bone in two different types of screw retained restorations (segmented vs. non-segmented abutment) using a finite element model. Methods. An implant, 4.1 mm in diameter and 10 mm in length, was placed in the first molar site of a mandibular model with 1 mm of cortical bone on the buccal and lingual sides. Segmented and non-segmented screw abutments with their crowns were placed on the simulated implant in each model. After loading (100 N, axial and 45 degrees non-axial), von Mises stress was recorded using ANSYS software, version 12.0.1. Results. The maximum stresses in the non segmented abutment screw were less than those of segmented abutment (87 vs. 100, and 375 vs. 430 MPa under axial and non-axial loading, respectively). The maximum stresses in the peri-implant bone for the model with segmented abutment were less than those of non-segmented ones (21 vs. 24 MPa, and 31 vs. 126 MPa under vertical and angular loading, respectively). In addition, the micro-strain of peri-implant bone for the segmented abutment restoration was less than that of non-segmented abutment. Conclusion. Under axial and non-axial loadings, non segmented abutment showed less stress concentration in the screw, while there was less stress and strain in the peri-implant bone in the segmented abutment. PMID- 29184630 TI - Effect of flap design and duration of surgery on acute postoperative symptoms and signs after extraction of lower third molars: A randomized prospective study. AB - Background. Different surgical variables are assumed to play a role in postoperative course after lower third molar extraction. The aim of study was to assess whether flap design and duration of surgery can influence acute postoperative symptoms and signs after lower third molar extraction. Methods. Twenty-five patients scheduled for lower third molar extraction were included in this study and randomly assigned to two groups in terms of flap design: group A (envelope flap) and group B (triangular flap). Swelling and trismus were assessed before and after surgery on days 0, 2 and 7. Pain was assessed for seven days after surgery. Maximum postoperative pain was chosen as the main outcome variable. ANOVA was used to assess differences between the groups regarding maximum postoperative pain, trismus and swelling at 2- and 7-day intervals. Pearson's correlation coefficient was used to assess correlation between duration of surgery and postoperative symptoms and signs. Results. No significant difference was found between the two flap designs for any postoperative symptoms and signs. The duration of surgery was found to be correlated with both trismus (r = -0.44, P = 0.04) and swelling (r = 0.59, P = 0.004) as assessed 2 days after surgery. No associations were found between duration of surgery and maximum postoperative pain and trismus and swelling at 7-day interval. Conclusion. Within the limits of the present study, the duration of surgery, and not the flap design, affected the acute postoperative symptoms and signs after lower third molar extraction. PMID- 29184631 TI - Comparison of the accuracy of conventional and digital radiography in root canal working length determination: An invitro study. AB - Background. Digital radiography has widespread use in endodontics. Determining a correct working length is vital for a proper endodontic therapy. The aim of this study was to compare the accuracy of conventional and digital radiographic techniques for root canal working length determination. Methods. After determining the real working lengths of 50 permanent maxillary central incisors (gold standard), the conventional (E- and F-speed films) and digital (CCD, PSP) images were obtained using the parallel technique. The mean registered working length of each modality was compared with the other and with the gold standard using one-way ANOVA at P<0.05. Results. No significant difference was found between the recorded working length values using the conventional and digital radiographic techniques (P=0.828). Conclusion. Within the limitations of this study, it was concluded that there was no difference between the measurement accuracy of CCD, PSP and conventional imaging techniques in root canal working length determination. PMID- 29184632 TI - Deep neck infection after third molar extraction: A case report. AB - Deep neck infections are associated with high morbidity rates in dentistry. Early diagnosis and intervention play an essential part in decreasing morbidity rates. The present study aims to report a case of odontogenic deep neck infection after third molar extraction. A 51-year-old male patient underwent extraction of the mandibular right third molar. Seven days later, the patient developed symptoms and signs of progressive infection. Laboratorial and radiologic examinations in association with clinical investigations confirmed deep neck infection. Extraoral drainage was performed under orotracheal intubation. Postoperative laboratory tests and clinical examinations revealed signs of complete remission within a follow-up period of 10 days. Considering the invasive nature of pathogens related to deep neck infections, it is possible to infer that a combination of accurate diagnosis and early intervention plays an essential role in the field of maxillofacial surgery and pathology.

AB - Background. This study was undertaken to assess the pathological and spatial associations between periapical and periodontal diseases of the maxillary first molars and thickening of maxillary sinus mucosa with cone-beam computed tomography. Methods. A total of 132 CBCT images of subjects 20-60 years of age were evaluated retrospectively. The patients' sex and age and demographic and pathologic findings of the maxillary sinus in the first molar area were recorded, graded and analyzed. Results. Approximately 59% of patients were male and 41% were female, with no significant difference in the thickness of schneiderian membrane between males and females. Based on the periapical index scoring, the highest frequency was detected in group 1. Based on the results of ANOVA, there were no significant differences in the frequencies of endodontic-periodontal lesions and an increase in schneiderian membrane thickness. There were significant relationships between periapical and periodontal infections (P<0.001) and schneiderian membrane thickness. Furthermore, a significant relationship was detected between the thickness of the schneiderian membrane and the distance between the sinus floor and the root apices (P=0.38). Conclusion. A retrospective inspection of CBCT imaging revealed that periapical lesions and periodontal infections in the posterior area of the maxilla were associated with thickening of the schneiderian membrane. In addition, there was a significant relationship between the location of maxillary posterior teeth, i.e. the thickness of bone from the root apex to the maxillary sinus floor, and schneiderian membrane thickness.

AB - Background. This in vitro study aimed to compare the antibacterial effect of different concentrations of sodium hypochlorite on elimination of Enterococcus faecalis from root canal systems of primary teeth with or without a passive sonic irrigation system (EndoActivator). Methods. The root canals of 120 extracted single-rooted primary incisors were prepared using the crown-down technique. The teeth were autoclaved and inoculated with E. faecalis. The infected samples were then randomly divided into 6 experimental groups of 15 and positive and negative control groups as follows: group 1: 0.5% sodium hypochlorite solution; group 2: 2.5% sodium hypochlorite solution; group 3: 5% sodium hypochlorite solution; group 4: 0.5% sodium hypochlorite solution + sonic activation; group 5: 2.5% sodium hypochlorite solution + sonic activation; and group 6: 5% sodium hypochlorite solution + sonic activation. Microbiological samples were collected before and after disinfection procedures and the colony-forming units were counted. Statistical analyses were performed using the two-way ANOVA and post hoc Duncan's tests in cases of significant difference. Results. There were no significant differences between the groups in any of the variables (concentration of antiseptic or use of sonic irrigation system). Conclusion. Use of passive sonic irrigation systems in endodontic treatment of single-rooted primary teeth is of no benefit compared to regular needle irrigation. The results of this study also recommends use of lower concentrations of sodium hypochlorite solution (0.5%) for irrigation of the root canal system rather than higher concentrations given approximately equal efficacy. PMID- 29184635 TI - Effect of denture cleansing agents on tensile and shear bond strengths of soft liners to acrylic denture base. AB - Background. The aim of the present study was to evaluate the effect of Corega and 2.5% sodium hypochlorite cleansing agents on the shear and tensile bond strengths of GC soft liner to denture base. Methods. A total of 144 samples (72 samples for tensile and 72 for shear bond strength evaluations) were prepared. The samples in each group were subdivided into three subgroups in terms of the cleansing agent used (2.5% sodium hypochlorite, Corega and distilled water [control group]). All the samples were stored in distilled water, during which each sample was immersed for 15 minutes daily in sodium hypochlorite or Corega solutions. After 20 days the tensile and shear bond strengths were determined using a universal testing machine. In addition, a stereomicroscope was used to evaluate fracture modes. Data were analyzed with one-way ANOVA, using SPSS 16. Results. The results of post hoc Tukey tests showed significant differences in the mean tensile and shear bond strength values between the sodium hypochlorite group with Corega and control groups (P=0.001 for comparison of tensile bond strengths between the sodium hypochlorite and control groups, and P<0.001 for the comparison of tensile bond strengths between the sodium hypochlorite and Corega groups and the shear bond strengths between the sodium hypochlorite and Corega groups, and sodium hypochlorite and control groups).The majority of failures were cohesive in the control and Corega groups and cohesive/adhesive in the sodium hypochlorite group. Conclusion. Immersion of soft liners in Corega will result in longevity of soft liners compared to immersion in sodium hypochlorite solution and sodium hypochlorite solution significantly decreased the tensile and shear bond strengths compared to the control and Corega groups. PMID- 29184636 TI - Efficacy of radiographic density values of the first and second cervical vertebrae recorded by CBCT technique to identify patients with osteoporosis and osteopenia. AB - Background. Osteoporosis is a systemic skeletal disease characterized by a decrease in bone strength with an increase in the risk of fractures. This study aimed at evaluating the ability to predict osteoporosis and osteopenia based on radiographic density values obtained from CBCT imaging technique. Methods. CBCT images of 108 patients were prepared by using NewTom VGI (QR, Verona, Italy). Then the patients were assigned to osteoporosis, osteopenia and healthy group, using the T-score derived from the DEXA technique. Finally, RD of the lateral mass of C1 on the left and right sides and body and dens of the C2 were measured. RD values were compared between the three groups by one-way ANOVA, followed by an appropriate post hoc test. Results. The results of the comparisons of RD values at the first and second cervical vertebrae in the three groups showed that all the values had statistically significant differences (P<0.05). The most precise diagnosis of osteoporosis was related to the RD values of the body of C2 and left lateral mass of C1 that was equal to 99% and their cut-off points were 375 and 386, respectively. Conclusion. Based on the findings of this study, it is possible to predict the osteoporosis status of the patient through the RD related to the body of C2 and the left lateral mass of C1 more accurately than the other areas. PMID- 29184637 TI - Preliminary study of a novel dental hand instrument for restorative procedures. AB - Background. There is no clear consensus on operative hand instrumentation. In general, there is one hand instrument that completes one task. Consequently, numerous instruments are required for the placement, shaping and carving of a restoration. This reduces clinical efficiency, increases cost and may generate frustration. Methods. A novel dental hand instrument has been developed. The instrument (GTI) can complete several tasks. The instrument was assessed in a laboratory setting with amalgam, composite and glass-ionomer restorations on dentoform teeth. Results. Results indicated that class II amalgam and composite restorations were significantly faster than conventional instrumentation (P<0.05). Differences in restoration quality were not statistically significant. Cost was significantly reduced as the GTI could perform the task of 9 conventional instruments. Conclusion. The GTI is an industry-translated, novel medical device that offers the clinician an alternative to standard instrumentation. Further investigations are required with increased samples sizes, clinical assessment and expanded utility. PMID- 29184638 TI - Promoting the Quality of Health Research-based News: Introduction of a Tool. AB - Introduction: While disseminating health research findings to the public, it is very important to present appropriate and accurate information to give the target audience a correct understanding of the subject matter. The objective of this study was to design and psychometrically evaluate a checklist for health journalists to help them prepare news of appropriate accuracy and authenticity. Methods: The study consisted of two phases, checklist design and psychometrics. Literature review and expert opinion were used to extract the items of the checklist in the first phase. In the second phase, to assess content and face validity, the judgment of 38 persons (epidemiologists with a tool production history, editors-in-chief, and health journalists) was used to check the items' understandability, nonambiguity, relevancy, and clarity. Reliability was assessed by the test-retest method using intra-cluster correlation (ICC) indices in the two phases. Cronbach's alpha was used to assess internal validity of the checklist. Results: Based on the participants' opinions, the items were reduced from 20 to 14 in number. The items were categorized into the following three domains: (a) items assessing the source of news and its validity, (b) items addressing the presentation of complete and accurate information on research findings, and (c) items which if adhered to lead to the target audiences' better understanding. The checklist was approved for content and face validity. The reliability of the checklist was assessed in the last stage; the ICC was 1 for 12 items and above 0.8 for the other two. Internal consistency (Cronbach's alpha) was 0.98. Discussion and Conclusions: The resultant indices of the study indicate that the checklist has appropriate validity and reliability. Hence, it can be used by health journalists to develop health research-based news. PMID- 29184639 TI - Social Determinants of Health and Attempt to Change Unhealthy Lifestyle: A Population-based Study. AB - Background: A healthy lifestyle is important because of its long-term benefits; however, there is a paucity of information concerning health choices among Iranians. We evaluated personal health behaviors, attempts to change unhealthy behaviors, and factors affecting attempts at change. Methods: The design of this cross-sectional study was to assemble a representative cadre of >18-year-old adults in Shiraz, Iran, using a multistage cluster sampling technique. Validated questionnaires collected participant's demographic information, such as weight, height, cigarette smoking history, physical activity, and attempts at lifestyle changes during the previous year. To determine predictors of attempts to change unhealthy lifestyle and to identify confounders, we applied single and multivariable logistic regression methods, respectively. A confidence interval of 95% was calculated for each odds ratio. Results: The prevalence of attempts to change unhealthy lifestyle was 42%, 64.8%, and 27.8%, respectively, for losing weight, being more physically active, and smoking cessation. Unemployment, low levels of education, and decreased socioeconomic status have important roles in attempts to change lifestyle conditions. Low socioeconomic status was a risk factor for quitting smoking. Occupation (unemployed/homemaker) and low level of education were two significant factors for being more physically active. Conclusions: The prevalence of inadequate physical activity and being overweight or obese was considerable in Shiraz, Iran. Attempts to change unhealthy lifestyle were less than ideal. Social determinants of health factors including unemployment and low levels of education and socioeconomic status play important roles in attempts to change current lifestyles. PMID- 29184640 TI - Investigation of Five Common Mutations on Phenylalanine Hydroxylase Gene of Phenylketonuria Patients from Two Provinces in North of Iran. AB - Background: There are more than 500 different mutations on phenylalanine hydroxylase (PAH) gene that is responsible for phenylketonuria (PKU) diseases and the spectrum of these mutations is varied in different populations. The main clinical manifestation of untreated patients is severe mental retardation. The PAH gene, that is 90 kb long, is consisted of 13 exons and 12 introns. The aim of the present study was to identify the frequency of five common mutations on PAH gene among patients with PKU in Mazandaran and Golestan provinces including c.1066-11G>A, p. R261Q, p. R252W, p. R261X, and c.1200 + 1G>C. Methods: Forty unrelated PKU patients, that 22 of them, were from Mazandaran and 18 of them from Golestan provinces were enrolled in the study. Genomic DNA was extracted from leukocytes using Qiagen DNA extraction kit and polymerase chain reaction - restriction fragment length polymorphism method was applied to detect five common mutations. Results: Three out of the 5 investigate mutations were identified among the patients. The c.1066-11G>A mutation has the highest frequency (27.5%) among the patients and the frequency of p. R261Q and p. R261X mutations were 3.75 and 1.25%, respectively. In Golestan province, only c.1066-11G>A mutation was observed in investigated alleles. Conclusions: The high frequency of c.1066-11G>A mutation in Golestan province may be related to genetic drift, founder effect, and consanguinity.

PMID- 29184641 TI - Modeling The Underlying Tobacco Smoking Predictors Among 1st Year University Students In Iran. AB - Background: There are scant studies on the prevalence and determinants of tobacco smoking among 1st year university students in Iran. We aim to determine the prevalence of substance abuse and identify factors related with tobacco smoking in 1st year students of Qazvin University of Medical Sciences (QUMS). Methods: A self-administered questionnaire was used to collect information on sociodemographic, cigarette smoking, hookah smoking, and related risk factors among 521 1st year students in QUMS between January and February 2014. We used logistic regression to determine factors associated with substance abuse among students. Results: The descriptive statistics indicated that the prevalence of lifetime cigarette and hookah smoking was 8.6% (confidence interval [CI] 95%: 6.5 11.4) and 35.5% (CI 95%: 31.5-39.7), respectively. After adjustment for other factors, being male, the presence of any smoker in the family and having smoker friends were factors associated with cigarette and hookah smoking among students. Our findings also revealed the co-occurrence of risk-taking behaviors among students. Conclusions: Our study showed considerably low prevalence of tobacco smoking among 1st year students. Longitudinal studies are necessary to approve the observed results of this study and thus allow for a certain generalization of the observations. PMID- 29184643 TI - Development of Caries Risk Assessment Tool for Iranian Preschoolers: A Primary Validation Study. AB - Background: The aim of the present study was to develop a dental caries risk assessment tool for Iranian preschoolers. Methods: In a validation and cross sectional study, a random sample of 150 preschool children was involved. This study was conducted in three phases: questionnaire design (expert panel and peer evaluation), questionnaire testing (pilot evaluation and field testing), and validation study. The initial assessments include interview, dental examination, and laboratory investigations. Validity and reliability indices, content validity index (CVI), content validity ratio (CVR), impact score, and test-retest and Cronbach's alpha were measured. Decayed, missing, filled teeth (dmft) scores were calculated according to the WHO guidelines. Results: The Iranian version of caries risk assessment (CRA) questionnaire contained 17 items. Cronbach's alpha coefficient (0.86) indicated a suitable internal consistency. The mean scores for the CVI and the CVR were 0.87 and 0.78, respectively. The prevalence rate of dental caries in the study group was 69.3%, and the mean dmft was 4.57 (range 0 19). Conclusions: The Persian version of CRA questionnaire was adapted to the Iranian population. The findings demonstrated overall acceptable validity and also reliability in the application of test-retest. The results of the present study provide initial evidence that the designed CRA form could be a useful tool for CRA in the Iranian preschoolers.

AB - Background: Classic phenylketonuria (PKU) is a metabolic disorder. The purpose of this study was to assess epidemiological factors of PKU phenotypes in a neonatal screening program for Mazandaran, Iran. Methods: In this descriptive retrospective study from 2007 to 2015, neonates PKU level was conducted by phenylalanine level based on a biochemical technique by ELISA and then by confirmatory methods high performance liquid chromatography. Results: Of the 407,244 screened newborns (48.7% girls and 51.3% boys), 14 girls and 13 boys were diagnosed definitely from 465 suspicious cases of PKU. The incidence of PKU was 0.66 in 10,000, which was noted in different severity (severe PKU - 1:67,874, mild PKU - 1:45,249, and HPA - 1:33,937). In addition, we did not detect any cases of nonclassic PKU. Conclusions: Although the consanguineous marriage pattern is a major cause of hyperphenylalaninemia (HPA) particularly in Iranian, there was no significant difference between groups in this study. Now, screening should be executed for all of the family that they have the familial history of PKU in Iran. According to varies actual of prevalence and incidence rate of PKU reported a real patient and taking PKU with mild PKU and HPA, it is recommended, the will provide the PKU reports based on the severity of the disease. PMID- 29184646 TI - Are Gender Differences in Health-related Quality of Life Attributable to Sociodemographic Characteristics and Chronic Disease Conditions in Elderly People? AB - Background: The objective of this study was to determine the gender differences in health-related quality of life (HRQoL) and to indicate to what extent this difference can be explained by differential in demographic and chronic disease conditions in Iranian elderly people. Methods: This analysis was carried out on cross-sectional data of QoL assessment among 750 elderly individuals aged 60-90 years who were dwelling in urban population of Babol, the North of Iran. The multiple linear regression model was used to estimate the association between gender and HRQoL after controlling sociodemographic characteristics and chronic disease conditions. Results: Women had significantly lower score in HRQoL in all subscales compared with men after adjusting several confounding factors (P = 0.001). The unadjusted mean difference in overall HRQoL scores was -11.2 (95% confidence interval [CI]: -13.8, -8.6) points, but it was reduced to -6.5 (95% CI: -9.0, -3.9) points between gender after adjusting by age, educational level, living status, physical activity, smoking, abdominal obesity, diabetes, and hypertension. Conclusions: Adjusting for sociodemographic and chronic disease conditions reduced the effect size of poorer HRQoL for women compared with men but did not remove the sex differences. The poorer scores of HRQoL in Iranian women needs further physical, psychological, and social supports in elderly. PMID- 29184647 TI - Medicinal Plants, Effective Plant Compounds (Compositions) and their Effects on Stomach Cancer. AB - Medicinal plants have special importance around the world. Further, they have been noticed for nutrition and illness treatment such as preparation of anticancer new drugs. Therefore, a wide range of studies have been done on different plants, and their anticancer effects have been investigated. Nowadays, cancer is the most important factor of death rate in the developed and developing countries. Among them, stomach cancer is one of the most common malignancies around the world. At present, it is recognized as the fourth common cancer and the second factor of death rate due to cancer. So far, there has been wide range of effort for cancer treatment; however, in most cases, the response to the treatment has been very weak and often accompanied improper subsidiary effects. The present problems as a consequence of chemical treatment and radiotherapy and many subsidiary problems created due to their use for patients, and also, the resistance to the current treatment has motivated researchers to apply new medicines with more effect and less toxicity. The secondary metabolisms existent in the plants have an important role in the treatment of several diseases such as cancer. This study was conducted to investigate and collect scientific results for stomach cancer and to clarify the role of medicinal plants and secondary plant compounds on its treatment. PMID- 29184648 TI - Estimating the prevalence of Positive Tuberculin Skin Test Reactions in General Population and High-risk Groups: A Meta-analysis. AB - Results of tuberculin skin test (TST) surveys among different populations have been reported in many studies as a method for detecting primary Mycobacterium tuberculosis infection. Combining these results provides reliable estimates of primary latent tuberculosis (TB) infection for health policymakers. This study aims to estimate the prevalence of latent TB infection in general and high-risk populations in Iran. National and international databanks were searched using specific keywords. After restricting the search strategy, duplicates exclusion, reviewing titles, abstracts and full texts, and quality assessment, eligible papers were selected. The heterogeneity between the results was assessed according to Cochrane and I-squared indices. The prevalence of positive TST reactions was estimated using fixed and random effect models. Totally, 33 papers were entered into the meta-analysis reporting the TST results in 12693 people aged over 18. The prevalence (95% confidence intervals) of positive TST reactions in all groups, general population, health staff, medical students, household close contacts, patients with TB, immunocompromised patients, HIV/AIDS patients, and those with risky behaviors was 26.2% (19.6-32.8), 25.4% (4.8-46.1), 38.9% (27.4-50.9), 13.4% (9.9-16.7), 35.9% (16.4-55.5), 13.7% (8.4-18.9), 29.4% (21.2 37.7), and 14.6% (3.9-25.3), respectively. Our study showed great varieties of positive TST results among different Iranian subpopulations. Furthermore, the prevalence of latent TB infection among health professionals and family members of TB patients was considerably different from that of the other subgroup. Since TB control programs such as active case finding are routinely conducted among household close contacts and HIV/AIDS cases, other high-risk groups including health-care workers and immunocompromised patients should be taken into consideration in these preventive programs.

AB - High dimensional mass and flow cytometry (HDCyto) experiments have become a method of choice for high throughput interrogation and characterization of cell populations.Here, we present an R-based pipeline for differential analyses of HDCyto data, largely based on Bioconductor packages. We computationally define cell populations using FlowSOM clustering, and facilitate an optional but reproducible strategy for manual merging of algorithm-generated clusters. Our workflow offers different analysis paths, including association of cell type abundance with a phenotype or changes in signaling markers within specific subpopulations, or differential analyses of aggregated signals. Importantly, the differential analyses we show are based on regression frameworks where the HDCyto data is the response; thus, we are able to model arbitrary experimental designs, such as those with batch effects, paired designs and so on. In particular, we apply generalized linear mixed models to analyses of cell population abundance or cell-population-specific analyses of signaling markers, allowing overdispersion in cell count or aggregated signals across samples to be appropriately modeled. To support the formal statistical analyses, we encourage exploratory data analysis at every step, including quality control (e.g. multi-dimensional scaling plots), reporting of clustering results (dimensionality reduction, heatmaps with dendrograms) and differential analyses (e.g. plots of aggregated signals). PMID- 29123644 TI - RNAi targeting Caenorhabditis elegans alpha-arrestins has little effect on lifespan. AB - Background: alpha-arrestins are a family of proteins that are implicated in multiple biological processes, including metabolism and receptor desensitization. Methods: Here, we sought to examine the roles of alpha-arrestins in the longevity of Caenorhabditis elegans through an RNA interference screen. Results: We found that knocking down each of 24 out of total 29 C. elegans alpha-arrestins had little effect on lifespan. Thus, individual C. elegans alpha-arrestins may have minor effects on longevity. Conclusions: This study will provide useful information for future research on the functional role of alpha-arrestins in aging and longevity.

PMID- 29152223 TI - Stage 1 Registered Report: Effect of deficient phagocytosis on neuronal survival and neurological outcome after temporary middle cerebral artery occlusion (tMCAo). AB - Stroke is a major cause of death and disability worldwide. In addition to neuronal death resulting directly from energy depletion due to lack of blood supply, inflammation and microglial activation following ischemic brain injury has been increasingly recognized to be a key contributor to the pathophysiology of cerebrovascular disease. However, our understanding of the cross talk between the ischemic brain and the immune system is limited. Recently, we demonstrated that following focal ischemia, death of mature viable neurons can be executed through phagocytosis by microglial cells or recruited macrophages, i.e. through phagoptosis. It was shown that inhibition of phagocytic signaling pathways following endothelin-1 induced focal cerebral ischemia leads to increased neuronal survival and neurological recovery. This suggests that inhibition of specific phagocytic pathways may prevent neuronal death during cerebral ischemia. To further explore this potential therapeutic target, we propose to assess the role of phagocytosis in an established model of temporary (45min) middle cerebral artery occlusion (tMCAo), and to evaluate neuronal survival and neurological recovery in mice with deficient phagocytosis. The primary outcome of this study will be forelimb function assessed with the staircase test. Secondary outcomes constitute Rotarod performance, stroke volume (quantified on MR imaging or brain sections, respectively), diffusion tensor imaging (DTI) connectome mapping, and histological analyses to measure neuronal and microglial densities, and phagocytic activity. Male mice aged 10-12 weeks will be used for experiments. PMID- 29184654 TI - On the need for multi-scale geometric modelling of the mitral heart valve. PMID- 29184655 TI - Editorial: Challenges for the usability of AR and VR for clinical neurosurgical procedures. AB - There are a number of challenges that must be faced when trying to develop AR and VR-based Neurosurgical simulators, Surgical Navigation Platforms, and "Smart OR" systems. Trying to simulate an operating room environment and surgical tasks in Augmented and Virtual Reality is a challenge many are attempting to solve, in order to train surgeons or help them operate. What are some of the needs of the surgeon, and what are the challenges encountered (human computer interface, perception, workflow, etc). We discuss these tradeoffs and conclude with critical remarks. PMID- 29184656 TI - Multimodal connectivity based eloquence score computation and visualisation for computer-aided neurosurgical path planning. AB - Non-invasive assessment of cognitive importance has been a major challenge for planning of neurosurgical procedures. In the past decade, in vivo brain imaging modalities have been considered for estimating the 'eloquence' of brain areas. In order to estimate the impact of damage caused by an access path towards a target region inside of the skull, multi-modal metrics are introduced in this paper. Accordingly, this estimated damage is obtained by combining multi-modal metrics. In other words, this damage is an aggregate of intervened grey matter volume and axonal fibre numbers, weighted by their importance within the assigned anatomical and functional networks. To validate these metrics, an exhaustive search algorithm is implemented for characterising the solution space and visually representing connectional cost associated with a path initiated from underlying points. In this presentation, brain networks are built from resting state functional magnetic resonance imaging (fMRI) and deterministic tractography. their results demonstrate that the proposed approach is capable of refining traditional heuristics, such as choosing the minimal distance from the lesion, by supplementing connectional importance of the resected tissue. This provides complementary information to help the surgeon in avoiding important functional hubs and their anatomical linkages; which are derived from neuroimaging modalities and incorporated to the related anatomical landmarks. PMID- 29184657 TI - Hand-eye calibration using a target registration error model. AB - Surgical cameras are prevalent in modern operating theatres and are often used as a surrogate for direct vision. Visualisation techniques (e.g. image fusion) made possible by tracking the camera require accurate hand-eye calibration between the camera and the tracking system. The authors introduce the concept of 'guided hand eye calibration', where calibration measurements are facilitated by a target registration error (TRE) model. They formulate hand-eye calibration as a registration problem between homologous point-line pairs. For each measurement, the position of a monochromatic ball-tip stylus (a point) and its projection onto the image (a line) is recorded, and the TRE of the resulting calibration is predicted using a TRE model. The TRE model is then used to guide the placement of the calibration tool, so that the subsequent measurement minimises the predicted TRE. Assessing TRE after each measurement produces accurate calibration using a minimal number of measurements. As a proof of principle, they evaluated guided calibration using a webcam and an endoscopic camera. Their endoscopic camera results suggest that millimetre TRE is achievable when at least 15 measurements are acquired with the tracker sensor ~80 cm away on the laparoscope handle for a target ~20 cm away from the camera. PMID- 29184658 TI - Real-time geometry-aware augmented reality in minimally invasive surgery. AB - The potential of augmented reality (AR) technology to assist minimally invasive surgery (MIS) lies in its computational performance and accuracy in dealing with challenging MIS scenes. Even with the latest hardware and software technologies, achieving both real-time and accurate augmented information overlay in MIS is still a formidable task. In this Letter, the authors present a novel real-time AR framework for MIS that achieves interactive geometric aware AR in endoscopic surgery with stereo views. The authors' framework tracks the movement of the endoscopic camera and simultaneously reconstructs a dense geometric mesh of the MIS scene. The movement of the camera is predicted by minimising the re projection error to achieve a fast tracking performance, while the three dimensional mesh is incrementally built by a dense zero mean normalised cross correlation stereo-matching method to improve the accuracy of the surface reconstruction. The proposed system does not require any prior template or pre operative scan and can infer the geometric information intra-operatively in real time. With the geometric information available, the proposed AR framework is able to interactively add annotations, localisation of tumours and vessels, and measurement labelling with greater precision and accuracy compared with the state of-the-art approaches. PMID- 29184660 TI - Robust head CT image registration pipeline for craniosynostosis skull correction surgery. AB - Craniosynostosis is a congenital malformation of the infant skull typically treated via corrective surgery. To accurately quantify the extent of deformation and identify the optimal correction strategy, the patient-specific skull model extracted from a pre-surgical computed tomography (CT) image needs to be registered to an atlas of head CT images representative of normal subjects. Here, the authors present a robust multi-stage, multi-resolution registration pipeline to map a patient-specific CT image to the atlas space of normal CT images. The proposed registration pipeline first performs an initial optimisation at very low resolution to yield a good initial alignment that is subsequently refined at high resolution. They demonstrate the robustness of the proposed method by evaluating its performance on 560 head CT images of 320 normal subjects and 240 craniosynostosis patients and show a success rate of 92.8 and 94.2%, respectively. Their method achieved a mean surface-to-surface distance between the patient and template skull of <2.5 mm in the targeted skull region across both the normal subjects and patients. PMID- 29184659 TI - Multi-modal imaging, model-based tracking, and mixed reality visualisation for orthopaedic surgery. AB - Orthopaedic surgeons are still following the decades old workflow of using dozens of two-dimensional fluoroscopic images to drill through complex 3D structures, e.g. pelvis. This Letter presents a mixed reality support system, which incorporates multi-modal data fusion and model-based surgical tool tracking for creating a mixed reality environment supporting screw placement in orthopaedic surgery. A red-green-blue-depth camera is rigidly attached to a mobile C-arm and is calibrated to the cone-beam computed tomography (CBCT) imaging space via iterative closest point algorithm. This allows real-time automatic fusion of reconstructed surface and/or 3D point clouds and synthetic fluoroscopic images obtained through CBCT imaging. An adapted 3D model-based tracking algorithm with automatic tool segmentation allows for tracking of the surgical tools occluded by hand. This proposed interactive 3D mixed reality environment provides an intuitive understanding of the surgical site and supports surgeons in quickly localising the entry point and orienting the surgical tool during screw placement. The authors validate the augmentation by measuring target registration error and also evaluate the tracking accuracy in the presence of partial occlusion. PMID- 29184661 TI - Application of an RGBD augmented C-arm for minimally invasive scoliosis surgery assistance. AB - Minimally invasive surgeries (MISs) are gaining popularity as alternatives to conventional open surgeries. In thoracoscopic scoliosis MIS, fluoroscopy is used to guide pedicle screw placement and to visualise the effect of the intervention on the spine curvature. However, cosmetic external appearance is the most important concern for patients, while correction of the spine and achieving coronal and sagittal trunk balance are the top priorities for surgeons. The authors present the feasibility study of the first intra-operative assistive system for scoliosis surgery composed of a single RGBD camera affixed on a C-arm which allows visualising in real time the surgery effects on the patient trunk surface in the transverse plane. They perform three feasibility experiments from simulated data based on scoliotic patients to live acquisition from non-scoliotic mannequin and person, all showing that the proposed system accuracy is comparable with scoliotic surface reconstruction state of art. PMID- 29184662 TI - Towards X-ray free endovascular interventions - using HoloLens for on-line holographic visualisation. AB - A major challenge during endovascular interventions is visualising the position and orientation of the catheter being inserted. This is typically achieved by intermittent X-ray imaging. Since the radiation exposure to the surgeon is considerable, it is desirable to reduce X-ray exposure to the bare minimum needed. Additionally, transferring two-dimensional (2D) X-ray images to 3D locations is challenging. The authors present the development of a real-time navigation framework, which allows a 3D holographic view of the vascular system without any need of radiation. They extract the patient's surface and vascular tree from pre-operative computed tomography data and register it to the patient using a magnetic tracking system. The system was evaluated on an anthropomorphic full-body phantom by experienced clinicians using a four-point questionnaire. The average score of the system (maximum of 20) was found to be 17.5. The authors' approach shows great potential to improve the workflow for endovascular procedures, by simultaneously reducing X-ray exposure. It will also improve the learning curve and help novices to more quickly master the required skills. PMID- 29184663 TI - Quantifying attention shifts in augmented reality image-guided neurosurgery. AB - Image-guided surgery (IGS) has allowed for more minimally invasive procedures, leading to better patient outcomes, reduced risk of infection, less pain, shorter hospital stays and faster recoveries. One drawback that has emerged with IGS is that the surgeon must shift their attention from the patient to the monitor for guidance. Yet both cognitive and motor tasks are negatively affected with attention shifts. Augmented reality (AR), which merges the realworld surgical scene with preoperative virtual patient images and plans, has been proposed as a solution to this drawback. In this work, we studied the impact of two different types of AR IGS set-ups (mobile AR and desktop AR) and traditional navigation on attention shifts for the specific task of craniotomy planning. We found a significant difference in terms of the time taken to perform the task and attention shifts between traditional navigation, but no significant difference between the different AR set-ups. With mobile AR, however, users felt that the system was easier to use and that their performance was better. These results suggest that regardless of where the AR visualisation is shown to the surgeon, AR may reduce attention shifts, leading to more streamlined and focused procedures. PMID- 29184664 TI - Estimation of surgical tool-tip tracking error distribution in coordinate reference frame involving pivot calibration uncertainty. AB - Accurate understanding of surgical tool-tip tracking error is important for decision making in image-guided surgery. In this Letter, the authors present a novel method to estimate/model surgical tool-tip tracking error in which they take pivot calibration uncertainty into consideration. First, a new type of error that is referred to as total target registration error (TTRE) is formally defined in a single-rigid registration. Target localisation error (TLE) in two spaces to be registered is considered in proposed TTRE formulation. With first-order approximation in fiducial localisation error (FLE) or TLE magnitude, TTRE statistics (mean, covariance matrix and root-mean-square (RMS)) are then derived. Second, surgical tool-tip tracking error in optical tracking system (OTS) frame is formulated using TTRE when pivot calibration uncertainty is considered. Finally, TTRE statistics of tool-tip in OTS frame are then propagated relative to a coordinate reference frame (CRF) rigid-body. Monte Carlo simulations are conducted to validate the proposed error model. The percentage passing statistical tests that there is no difference between simulated and theoretical mean and covariance matrix of tool-tip tracking error in CRF space is more than 90% in all test cases. The RMS percentage difference between simulated and theoretical tool-tip tracking error in CRF space is within 5% in all test cases. PMID- 29184665 TI - Distance sonification in image-guided neurosurgery. AB - Image-guided neurosurgery, or neuronavigation, has been used to visualise the location of a surgical probe by mapping the probe location to pre-operative models of a patient's anatomy. One common limitation of this approach is that it requires the surgeon to divert their attention away from the patient and towards the neuronavigation system. In order to improve this type of application, the authors designed a system that sonifies (i.e. provides audible feedback of) distance information between a surgical probe and the location of the anatomy of interest. A user study (n = 15) was completed to determine the utility of sonified distance information within an existing neuronavigation platform (Intraoperative Brain Imaging System (IBIS) Neuronav). The authors' results were consistent with the idea that combining auditory distance cues with existing visual information from image-guided surgery systems may result in greater accuracy when locating specified points on a pre-operative scan, thereby potentially reducing the extent of the required surgical openings, as well as potentially increasing the precision of individual surgical tasks. Further, the authors' results were also consistent with the hypothesis that combining auditory and visual information reduces the perceived difficulty in locating a target location within a three-dimensional volume. PMID- 29184667 TI - Design and evaluation of an augmented reality simulator using leap motion. AB - Advances in virtual and augmented reality (AR) are having an impact on the medical field in areas such as surgical simulation. Improvements to surgical simulation will provide students and residents with additional training and evaluation methods. This is particularly important for procedures such as the endoscopic third ventriculostomy (ETV), which residents perform regularly. Simulators such as NeuroTouch, have been designed to aid in training associated with this procedure. The authors have designed an affordable and easily accessible ETV simulator, and compare it with the existing NeuroTouch for its usability and training effectiveness. This simulator was developed using Unity, Vuforia and the leap motion (LM) for an AR environment. The participants, 16 novices and two expert neurosurgeons, were asked to complete 40 targeting tasks. Participants used the NeuroTouch tool or a virtual hand controlled by the LM to select the position and orientation for these tasks. The length of time to complete each task was recorded and the trajectory log files were used to calculate performance. The resulting data from the novices' and experts' speed and accuracy are compared, and they discuss the objective performance of training in terms of the speed and accuracy of targeting accuracy for each system. PMID- 29184666 TI - Intra-operative ultrasound-based augmented reality guidance for laparoscopic surgery. AB - In laparoscopic surgery, the surgeon must operate with a limited field of view and reduced depth perception. This makes spatial understanding of critical structures difficult, such as an endophytic tumour in a partial nephrectomy. Such tumours yield a high complication rate of 47%, and excising them increases the risk of cutting into the kidney's collecting system. To overcome these challenges, an augmented reality guidance system is proposed. Using intra operative ultrasound, a single navigation aid, and surgical instrument tracking, four augmentations of guidance information are provided during tumour excision. Qualitative and quantitative system benefits are measured in simulated robot assisted partial nephrectomies. Robot-to-camera calibration achieved a total registration error of 1.0 +/- 0.4 mm while the total system error is 2.5 +/- 0.5 mm. The system significantly reduced healthy tissue excised from an average (+/ standard deviation) of 30.6 +/- 5.5 to 17.5 +/- 2.4 cm3 (p < 0.05) and reduced the depth from the tumor underside to cut from an average (+/-standard deviation) of 10.2 +/- 4.1 to 3.3 +/- 2.3 mm (p < 0.05). Further evaluation is required in vivo, but the system has promising potential to reduce the amount of healthy parenchymal tissue excised. PMID- 29184668 TI - Can surgical simulation be used to train detection and classification of neural networks? AB - Computer-assisted interventions (CAI) aim to increase the effectiveness, precision and repeatability of procedures to improve surgical outcomes. The presence and motion of surgical tools is a key information input for CAI surgical phase recognition algorithms. Vision-based tool detection and recognition approaches are an attractive solution and can be designed to take advantage of the powerful deep learning paradigm that is rapidly advancing image recognition and classification. The challenge for such algorithms is the availability and quality of labelled data used for training. In this Letter, surgical simulation is used to train tool detection and segmentation based on deep convolutional neural networks and generative adversarial networks. The authors experiment with two network architectures for image segmentation in tool classes commonly encountered during cataract surgery. A commercially-available simulator is used to create a simulated cataract dataset for training models prior to performing transfer learning on real surgical data. To the best of authors' knowledge, this is the first attempt to train deep learning models for surgical instrument detection on simulated data while demonstrating promising results to generalise on real data. Results indicate that simulated data does have some potential for training advanced classification methods for CAI systems. PMID- 29184670 TI - The era of a "liquid biopsy" may be on the horizon in non-small cell lung cancer. PMID- 29184669 TI - Repeat dose NRPT (nicotinamide riboside and pterostilbene) increases NAD+ levels in humans safely and sustainably: a randomized, double-blind, placebo-controlled study. AB - NRPT is a combination of nicotinamide riboside (NR), a nicotinamide adenine dinucleotide (NAD+) precursor vitamin found in milk, and pterostilbene (PT), a polyphenol found in blueberries. Here, we report this first-in-humans clinical trial designed to assess the safety and efficacy of a repeat dose of NRPT (commercially known as Basis). NRPT was evaluated in a randomized, double-blind, and placebo-controlled study in a population of 120 healthy adults between the ages of 60 and 80 years. The study consisted of three treatment arms: placebo, recommended dose of NRPT (NRPT 1X), and double dose of NRPT (NRPT 2X). All subjects took their blinded supplement daily for eight weeks. Analysis of NAD+ in whole blood demonstrated that NRPT significantly increases the concentration of NAD+ in a dose-dependent manner. NAD+ levels increased by approximately 40% in the NRPT 1X group and approximately 90% in the NRPT 2X group after 4 weeks as compared to placebo and baseline. Furthermore, this significant increase in NAD+ levels was sustained throughout the entire 8-week trial. NAD+ levels did not increase for the placebo group during the trial. No serious adverse events were reported in this study. This study shows that a repeat dose of NRPT is a safe and effective way to increase NAD+ levels sustainably. PMID- 29184671 TI - Urine test for EGFR analysis in patients with non-small cell lung cancer. AB - Precision medicine approaches in oncology are reliant on the accurate genomic characterization of tumors. While tissue remains the mainstay specimen for molecular testing, tumor biopsies are riddled with challenges and limitations due to their invasive and site-specific nature. Tumor inaccessibility and intratumoral heterogeneity, in particular, represent significant obstacles to the identification of actionable genetic alterations and hence effective mono- and combination therapy strategies. Proof-of-concept studies indicate that circulating tumor DNA (ctDNA) released from multiple tumor regions and anatomical locations is more reflective of intra- and intertumoral heterogeneity. Non invasive liquid biopsy approaches that allow for the analysis of ctDNA are thus being increasingly implemented in routine patient care for the detection and monitoring of cancer-associated mutations. Indeed, the use of plasma testing to screen for epidermal growth factor receptor (EGFR) T790M mutant positive non small cell lung cancer (NSCLC) patients eligible for treatment with third generation EGFR inhibitors was recently approved by the U.S. Food and Drug Administration and is incorporated into the most recent version of the National Comprehensive Cancer Center guidelines as an alternative to tissue biopsy. Urine represents another liquid biopsy specimen that is distinguished by its ease of collection, option for home collection, and lack of temporal and volumetric collection restrictions. Importantly, there is an accumulating body of evidence supporting the clinical validity of urinary EGFR mutant testing for the identification and stratification of patients likely to benefit from EGFR directed therapies and as a means to assess patient response, the presence of residual disease, and emergence of resistant tumor cell populations. PMID- 29184673 TI - Critical issues in the clinical application of liquid biopsy in non-small cell lung cancer. AB - Current therapeutic options for non-small cell lung cancer (NSCLC) patients are chemotherapy and targeted therapy directed mainly against epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) rearrangements. Targeted therapy relies on the availability of tumor biopsies for molecular profiling at diagnosis and to longitudinally monitor treatment response and resistance development. Unfortunately, tumor biopsy might be invasive, recover poor material of suboptimal quality, and cause sample bias due to tumor heterogeneity. Many studies have illustrated the potential of liquid biopsy as minimal invasive approach to respond to the urgent need for real time monitoring, stratification, and personalized optimized treatment in NSCLC patients. In principle, the liquid biopsy could provide the genetic landscape of primary and metastatic cancerous lesions, detecting "druggable" genomic alterations or associated with treatment resistance. Moreover, it would guarantee the prognostic/predictive biomarkers evaluation in patients for whom biopsies are inaccessible or difficult to repeat. At this regard, the prognostic value of circulating tumor cells (CTCs) in NSCLC patients has been largely investigated, but still their clinical utility as tumor biomarker is hampered by the lack of a consensus on the criteria necessary and sufficient to define them and on the standard operating procedures (SOPs) for their assessment. This review will summarize current developments on liquid biopsy in NSCLC, addressing the technology issues that contribute to the poor ability to track CTCs in the blood of NSCLC patients, thus limiting their extensive use in the clinical practice, and analyzing the solutions adopted to overcome such limits, on the road towards the clinical validation. PMID- 29184672 TI - New insights in non-small-cell lung cancer: circulating tumor cells and cell-free DNA. AB - Lung cancer is the second most frequent tumor and the leading cause of death by cancer in both men and women. Increasing knowledge about the cancer genome and tumor environment has led to a new setting in which morphological and molecular characterization is needed to treat patients in the most personalized way in order to achieve better outcomes. Since tumor products can be detected in body fluids, the liquid biopsy, particularly, peripheral blood, has emerged as a new source for lung cancer biomarker's analysis. A variety of tumor components can be used for this purpose. Among them, circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) should be especially considered. Different detection methods for both CTCs and ctDNA have been and are being developed to improve the sensitivity and specificity of these tests. This would lead to better characterization and would solve some clinical doubts at different disease evolution times, e.g., intratumoral or temporal heterogeneity, difficulty in the obtaining a tumor sample, etc., and would also avoid the side effects of very expensive and complicated tumor obtaining interventions. CTCs and ctDNA are useful in different lung cancer settings. Their value has been shown for the early diagnosis, prognosis, prediction of treatment efficacy, monitoring responses and early detection of lung cancer relapse. CTCs have still not been validated for use in clinical settings in non-small-cell lung cancer (NSCLC), while ctDNA has been approved by the Food and Drug Administration (FDA) and European Medical Association (EMA), and the main clinical guidelines used for detect different epidermal growth factor receptor (EGFR) mutations and the monitoring and treatment choice of mutated patients with tyrosine kinase inhibitors (TKIs). This review, describes how ctDNA seem to be winning the race against CTCs from the laboratory bench to clinical practice due to easier obtaining methods, manipulation and its implementation into clinical practice. PMID- 29184674 TI - Molecular characterization and prognostic significance of circulating tumor cells in patients with non-small cell lung cancer. AB - Circulating tumor cells (CTCs) are rare epithelial cells that can be found in the peripheral blood of cancer patients. A growing body of evidence indicates that CTCs may play a role in non-small cell lung cancer (NSCLC) for diagnosis, therapy monitoring and prognostic purposes. CTCs evaluation could be particularly relevant in this clinical setting, considering that physicians often have difficulty in obtaining an adequate tumor tissue and that patients are not always suitable to receive a re-biopsy. In the current review, we will focus on the molecular characterization and prognostic significance of CTCs in NSCLC patients. PMID- 29184676 TI - Exosomes as diagnostic and predictive biomarkers in lung cancer. AB - The concept of exosomes has evolved from be considered garbage bags to the demonstration that exosomes could play very interesting roles and functions, from biomarkers detection to the potential of work as drug delivery systems. It has been widely proved that exosomes can contain key molecules important for the tumour development. The current review summarizes the latest investigations developed in the field of predictive exosomal biomarkers. The microRNAs (miRNAs) are the more known molecules due to their amount inside the exosomes and the sensitivity of the techniques available for their study. However, exosomal proteins, RNA and DNA are becoming an interesting and more feasible field of study due to the improvement in the techniques available for their analysis. In the future years, it is hoped that exosomes will become an established member of the liquid biopsies in the clinical practice due to their diagnostic and prognostic properties. PMID- 29184675 TI - Possible application of circulating free tumor DNA in non-small cell lung cancer patients. AB - Liquid biopsies have been heralded as a game changer in cancer management. Blood tests offer a minimally invasive, safe and sensitive complementary (or even alternative) approach for tissue biopsies. With lung cancer being the second most commonly diagnosed cancer and the leading cause of cancer deaths worldwide, due to the limitations of tissue sampling, liquid biopsies must urgently materialize in the clinic. In this short review, we will present the current applications of cell-free DNA (cfDNA) in lung cancer management, emphasizing on our own experience and previous work. We will also shortly comment on the challenges and need for a coordinated collaboration combining disciplines and sectors (from academia to health economies) in order to accelerate liquid biopsy development in lung cancer and other cancers. PMID- 29184677 TI - Cell free DNA analysis by SiRe(r) next generation sequencing panel in non small cell lung cancer patients: focus on basal setting. AB - Background: Non small cell lung cancer (NSCLC) is diagnosed in most cases on small tissue samples, such as cytological preparations and histological biopsies; these limited tissue specimens may be not always sufficient for testing epidermal growth factor receptor (EGFR) mutations and other relevant predictive biomarkers. Cell-free DNA (cfDNA) can be used as a surrogate for EGFR mutational testing, whenever tissue is unavailable. However, the detection of gene mutations on cfDNA is challenging; in fact, the extremely low concentration of circulating tumor DNA requires the implementation of highly sensitive and validated next generation techniques. Methods: Thus, we have recently validated a novel next generation sequencing (NGS) assay, employing the SiRe(r) gene panel to detect on cfDNA mutations of EGFR and KRAS, NRAS, BRAF, cKIT and PDGFR genes. In this current study, we report on a series of NSCLC patients, without available tissue for EGFR testing, who prospectively underwent SiRe(r) NGS analysis. Results: The results confirm the high clinical performance, in terms of success rate and mutation detection, of NGS based analysis of cfDNA. Conclusions: SiRe(r) NGS panel represent an effective diagnostic tool in cfDNA analysis setting. PMID- 29184678 TI - Liquid biopsy for monitoring anaplastic lymphoma kinase inhibitors in non-small cell lung cancer: two cases compared. AB - Three to seven percent of non-small cell lung cancer (NSCLC) patients show anaplastic lymphoma kinase (ALK)-translocation and could be treated with ALK inhibitors. However, under crizotinib, a first-generation ALK-inhibitor, patients develop drug resistance after a median of 12 months. To overcome crizotinib resistance, several next-generation ALK inhibitors have been developed. In NSCLC, liquid biopsy allowed important improvements in the detection of the epidermal growth factor receptor (EGFR) mutation. The ability of liquid biopsy to detect oncogenic gene/protein fusions is a newly investigated field, and is not routinely applied yet. We here present two NSCLC patients, both rearranged for echinoderm microtubule associated-protein like 4-anaplastic lymphoma kinase (EML4 ALK) and treated accordingly, who differed in the clinical outcome. We analyzed the predictive value of the liquid biopsy components, namely epithelial cellular adhesion molecule (EpCAM)+ circulating tumor cells (CTCs), EpCAM low/neg CTCs, EML4-ALK rearranged CTCs, and cell-free mRNA (cfmRNA), during ALK-inhibitors treatment. This analysis showed a potential association between the liquid biopsy biomarkers, patients' outcome and response to treatment, thus suggesting their combined use in the clinical practice, as proposed here. This approach would allow longitudinal monitoring and consequent identification of putative drug resistance mechanisms, in the light of improving high-risk patient management. PMID- 29184679 TI - Outcomes of adjuvant radiotherapy and lymph node resection in elderly patients with pancreatic cancer treated with surgery and chemotherapy. AB - Background: We sought to determine the effects of post-operative radiation therapy (PORT) and lymph node resection (LNR) on survival in patients >=70 years with pancreatic cancer treated with surgery and chemotherapy. Methods: An analysis of patients >=70 years with surgically resected pancreatic cancer who received chemotherapy from the SEER database between 2004-2008 was performed to determine association of PORT and LNR on survival. Results: We identified 961 patients who met inclusion criteria. There was a trend towards increased survival associated with PORT in all patients (P=0.052) and N1 patients (P=0.060) but no benefit in N0 patients (P=0.161). There was no difference in OS based on number of lymph nodes removed in all (P=0.741), N0 (P=0.588), and N1 (P=0.070) patients. MVA for all patients revealed that higher T stage, N1, and high grade tumors were prognostic for increased mortality, while there was decreased mortality with PORT and mild benefit with increased lymph nodes resected (P=0.084). Conclusions: PORT demonstrated no benefit in survival of pancreatic cancer patients >=70 who are resected and treated with adjuvant chemotherapy. Future investigation will need to address age as a stratification factor for pancreatic cancer in the adjuvant setting. PMID- 29184680 TI - Stereotactic body radiotherapy for locally-advanced unresectable pancreatic cancer-patterns of care and overall survival. AB - Background: Unresectable pancreatic cancer remains a challenging disease to treat. Stereotactic body radiotherapy (SBRT) allows for a higher biologically equivalent dose in an abbreviated course more convenient for patients and the integration of systemic therapy. We sought to investigate utilization trends and survival outcomes for patients treated with pancreatic SBRT versus conventionally fractionated radiotherapy (CFRT). Methods: We engaged the National Cancer Database (NCDB) from 1998-2012 and identified locally-advanced unresectable patients with histologically confirmed, non-metastatic, pancreatic adenocarcinoma who received radiotherapy. Patients who received CFRT (1.5-4.0 Gy per fraction to a dose of >=45 Gy, n=11,879) were compared to those who received SBRT (6-15 Gy per fraction to a dose of >=20 Gy, n=474). Results: Median follow-up was 11.0 months (18.4 months for survivors). SBRT utilization increased from 0.2% to 7.4% from 1998 to 2012 (P<0.05). On multivariable analysis, factors predictive for preferential utilization of SBRT over CFRT were later year of diagnosis, age >=75 years, increased facility volume, and no chemotherapy in the initial treatment plan. Unadjusted median survival was 11.2 months for CFRT vs. 12.6 months for SBRT (P=0.002). Results were consistent in the propensity matched model. Variables predictive for improved survival on multivariable analysis were diagnosis after 2010, younger age, lower comorbidity score, tumor size <3 cm, nodal stage zero, and receipt of chemotherapy (P<0.05). Conclusions: SBRT utilization has increased significantly and is associated with a small absolute improvement in overall survival (OS) compared to CFRT. The decreased treatment time, without apparent compromise in survival, makes SBRT an attractive option for patients with unresectable pancreatic cancer warranting further research. PMID- 29184681 TI - Prognostic impact of carbohydrate antigen 19-9 level at diagnosis in resected stage I-III pancreatic adenocarcinoma: a U.S. population study. AB - Background: Pancreatic adenocarcinoma is a highly aggressive cancer, with surgical resection and systemic therapy offering the only hope for long-term survival. Carbohydrate antigen 19-9 (CA 19-9) has been used as a prognostic marker after resection; however, the relationship between survival and pre treatment CA 19-9 level remains unclear. This study evaluates pre-treatment serum CA 19-9 level as a predictor for long-term survival. Methods: The U.S. National Cancer Data Base [2004-2012] was reviewed for patients with clinical stages I-III resected pancreatic adenocarcinoma with recorded pre-treatment CA 19-9 levels (U/mL). Kaplan Meier and Weibull survival analyses were performed. Results: Four thousand seven hundred and one patients were included: 12.6% received neoadjuvant therapy (NAT), 27.4% underwent surgery, and 60.1% underwent surgery and adjuvant therapy. Amongst those who underwent initial surgery, there was no association between CA 19-9 levels <=800 (<=100, 101-300, 301-500, 501-800) with survival (stage I P=0.7592, stage II P=0.5088, stage III P=0.9037). Levels >800 were associated with significantly worse survival in all stages (P<=0.0001, all). Amongst those who received NAT, levels >800 were associated with worse survival in early (stage I P=0.0001), but not advanced stage disease (stage II P=0.1891, stage III P=0.9316). In multivariable analyses, levels >800 demonstrated a 3.29 greater hazard of mortality with respect to patients with levels <=100 (P<0.0001). Conclusions: Pre-treatment CA 19-9 levels >800 appear to be associated with advanced disease, and are negatively associated with long-term survival. However, levels <=800 had no significant association with survival. Although this study suggests an association, further study is needed to evaluate whether patients with CA 19-9 levels >800 benefit from NAT. PMID- 29184682 TI - Survival differences among patients with hepatocellular carcinoma based on the stage of disease and therapy received: pre and post sorafenib era. AB - Background: The incidence of hepatocellular carcinoma (HCC) is increasing. Development of newer therapeutic modalities has changed the paradigm of HCC treatment in recent years. So, the aim of our study is to analyze the impact of these treatment modalities into the survival of HCC patients, based on the stage of HCC in real life practice. Methods: We analyzed the data from the SEER database: Incidence - SEER 18 Regs Research Data + Hurricane Katrina Impacted Louisiana Cases, Nov 2015 Sub (1973-2013 varying). Relative survival rates (RSRs) and hazard ratios (HRs) were measured for patients diagnosed with HCC between 2001 and 2013. Rates were compared between pre sorafenib [2001-2007] and post sorafenib [2008-2013] eras. Results: A total of 50,088 patients (21,435 in pre sorafenib era and 28,653 in the post-sorafenib era) were included with HCC from SEER database. The median relative survival for the entire population was 14 months with 5-year RSR of 21.20%; 11 months for those diagnosed in 2001-2007 with 5-year RSR 19.30% and 17 months for those diagnosed in 2008-2013 with 5-year RSR 22.40% (P<0.01). This survival improvement was largely limited to HCC patients with single nodule (5-year RSR; 35.1% vs. 37.00% for pre and post sorafenib era respectively; P value <0.01) and multiple nodules without vascular invasion (5 year RSR; 19.90% vs. 22.60% for pre and post sorafenib era respectively; P value <0.01). RSR remained extremely poor with no significant improvement for advanced stage HCC who had vascular invasion (P=0.37) or distant metastasis (P=0.10), respectively for pre and post sorafenib era in each category. Survival improved since 2008, for HCC patients who received either no surgical intervention (P<0.01) or received tumor-directed therapy (P<0.01), however, it remained significantly poor compared to the patients who received lobectomy or hepatectomy and transplant. Approximately 70% of patients from our study population did not receive any HCC directed surgical intervention and among this, more than 40% of patients were with single nodule in the liver. Conclusions: Survival in patients with HCC has improved since 2008, which is limited to early stage HCC. Survival of advanced stage HCC patients is extremely poor and has not shown any significant improvement since the approval of sorafenib, emphasizing the need for better therapeutic options. Not receiving any surgical intervention is associated with significantly poor prognosis. Large numbers of early stage HCC patients were not able to receive surgical interventions. This can impose a significant financial burden, as these patients would progress on to the advanced stage, where treatment options are very limited and not as cost-effective. This emphasizes the need for further research to identify various barriers and the possible need for healthcare policy changes. PMID- 29184683 TI - Selective internal radiation therapy using yttrium-90 resin microspheres in patients with unresectable hepatocellular carcinoma: a retrospective study. AB - Background: Selective internal radiation therapy (SIRT) with yttrium-90 resin (Y 90 resin) microspheres has been used as a locoregional therapy for patients with unresectable hepatocellular carcinoma (HCC). We examined patient and disease characteristics that might affect survival after Y-90 resin, as well as treatment tolerability. Methods: Data from patients with unresectable HCC treated with Y-90 resin at a single institution were reviewed retrospectively. Survival was assessed with Kaplan-Meier curves and log-rank tests. Response was evaluated with the response evaluation criteria in solid tumors (RECIST) criteria. Adverse events (AEs) were noted, and laboratory values were graded with CTCAE v3.0. Results: Data from 111 patients were analyzed. AEs occurred in 23 patients at 1 week after treatment and in 46 at 3 months. At 6 months, 13 patients had a complete response and 13 had a partial response. Factors associated with longer overall survival (OS) included early-stage disease [27.8 months for patients with Barcelona-Clinic Liver Cancer (BCLC) A vs. 9.2 months for BCLC C]; treatment with other locoregional therapies (69.0 vs. 11.4 months); and lack of bilobar disease (23.5 vs. 9.4 months), portal vein thrombosis (16.2 vs. 8.6 months), ascites (16.6 vs. 10.3 months), and treatment with sorafenib (17.2 vs. 10.3 months). In six patients, Y-90 resin was used as a bridge to liver transplantation, which greatly improved survival (69.0 vs. 12.1 months). Conclusions: Several characteristics may prove useful for selecting patients likely to respond well to Y-90 resin. These results should be confirmed in prospective studies. PMID- 29184684 TI - Impact of sarcopenia on outcomes of locally advanced esophageal cancer patients treated with neoadjuvant chemoradiation followed by surgery. AB - Background: Sarcopenia is an independent predictor of clinical outcomes in multiple gastrointestinal cancers. Total psoas area (TPA), as measured on a single cross-sectional CT image at the L4 vertebral body level, has been correlated with sarcopenia. We sought to evaluate whether TPA was predictive of acute grade >=3 toxicity, pathologic response, and overall survival in patients with locally advanced esophageal cancer receiving tri-modality therapy. Methods: An institutional database of esophageal cancer patients treated with neoadjuvant chemoradiation followed by surgery was queried. Of 77 patients treated from 2008 to 2012 with intensity modulated radiation therapy (IMRT) and image guided radiation therapy (IGRT), 56 patients were eligible based on having CT imaging that included the L4 vertebral body. The L4 vertebra was identified on axial CT and the psoas muscle was manually contoured bilaterally to determine the skeletal muscle index. Sarcopenia was defined by the presence of the psoas area less than the median of the cohort. Acute toxicity was defined as within 3 months of radiotherapy based on Common Terminology Criteria for Adverse Events. ROC curve, logistic regression, and Kaplan Meier estimates were used when appropriate. Results: Sarcopenia was associated with increased acute grade >=3 toxicity from chemoradiation by ROC analysis using a cut off of 841.5 mm2/m2 (P=0.003, AUC 0.709, sensitivity 60.9%, specificity 78.8%) and logistic regression (P=0.002). Patients with TPA <841.5 mm2/m2 were 5.78 times more likely to develop grade 3 or higher toxicity (P=0.004). Sarcopenia did not predict a difference in overall survival (P=0.217) and was not significant for pathologic complete response or favorable pathologic response (TRG 0/1). Conclusions: In our cohort of patients, sarcopenia was associated with a significant increase in acute grade >=3 toxicity with chemoradiation, suggesting a potential role for neoadjuvant patient selection strategies. There was no difference in pathologic response or overall survival. PMID- 29184685 TI - Adjuvant chemotherapy and outcomes in esophageal carcinoma. AB - Background: Standard treatment for locally advanced esophageal cancer is neoadjuvant chemoradiation followed by surgery. The role of postoperative chemotherapy is unclear. We sought to determine the indications, patterns, and outcomes for adjuvant chemotherapy in esophageal carcinoma. Methods: This single institution retrospective review included patients with esophageal cancer who received neoadjuvant chemoradiation and surgery at Moffitt. We identified patients in this cohort who additionally received adjuvant chemotherapy. Medical records were reviewed for demographic/clinical information. Survival was estimated using the Kaplan-Meier method and compared by log-rank. Case-control analysis was performed using a 2:1 nearest neighbor propensity score matching algorithm, which included 92 without adjuvant chemotherapy and 46 with adjuvant chemotherapy. Results: We identified 382 patients, 46 of whom received adjuvant chemotherapy. Patients who received adjuvant chemotherapy were younger (60.2 vs. 63.8 years; P=0.047), more likely to have adenocarcinoma (91% vs. 85%; P=0.034), had more advanced ypT and ypN classifications (P<0.001), less response to neoadjuvant therapy (P<0.001), and more margin positivity (15% vs. 4%; P=0.007). With propensity score matching analysis, no variables were significantly different between the two matched groups. Median follow-up times for the entire cohort and for case-control analysis were 2.9 and 2.4 years, respectively. There were no significant differences in overall or recurrence-free survival (RFS) between groups in either analysis. Conclusions: The role of adjuvant chemotherapy following neoadjuvant chemoradiation and surgery in esophageal cancer is unclear. We found no significant difference in survival based on adjuvant chemotherapy. Future prospective studies should further investigate potential survival benefits and morbidity. PMID- 29184687 TI - CT-based assessment of visceral adiposity and outcomes for esophageal adenocarcinoma. AB - Background: Various methods of quantifying and correlating obesity to outcomes for patients with esophageal adenocarcinoma (EA) have been evaluated. Published data suggest that quantification of adiposity may be more accurate than body mass index (BMI) as a prognostic factor. We report our analysis of adiposity as a prognostic factor in a series of patients with EA. Methods: This single institution retrospective review included patients with EA who underwent esophagectomy from 1994-2008. Patients with BMI <20 were excluded. Using the preoperative CT scan, the visceral (VFA), subcutaneous (SFA), and total abdominal fat (TFA) areas were calculated. Each was contoured on a Siemens Leonardo workstation at the level of the iliac crest (L4/5). The Hounsfield threshold was 30 to -130. Outcomes were analyzed using Kaplan-Meier method and log-rank analysis. Multivariate analysis (MVA) was performed using the Cox proportion hazard regression model. Results: We identified 126 patients for the analysis. There were no statistically significant differences in overall survival or disease-free survival between groups above and below the medians for TFA, SFA, or VFA/SFA ratio. However, an increase in VFA was significantly associated with worsened OS and DFS when we further classified patients into quartiles. Patients with VFA >=182 cm2 had larger tumor size (P=0.016), fewer involved lymph nodes (P=0.047), longer operating times (P=0.032), and were more likely to be males (P=0.042). Conclusions: Published data have demonstrated an association between treatment outcomes and degree of adiposity; our study found a correlation between VFA and OS and DFS in patients with EA. Median TFA, SFA, and VFA/SFA were not prognostic on MVA. While VFA >182 cm2 was associated with larger tumors, there were also fewer lymph nodes harvested in this group. PMID- 29184686 TI - Survival benefit of neoadjuvant versus adjuvant radiotherapy in lymph node positive esophageal cancer: a population based analysis. AB - Background: The impact of radiotherapy on the survival of patients with locally advanced esophageal cancer (EC) is presently insufficiently explored. Thus, using data from the Surveillance, Epidemiology, and End Results (SEER) Registry, this study aimed to compare the survival rates of patients with lymph node (LN) positive EC who received curative resection and were treated by neoadjuvant and adjuvant radiotherapy (RT), respectively. Methods: Retrospectively collected data from the SEER database using all 18 SEER registries on patients that underwent esophagectomy for EC was evaluated. All patients with LN positive pathology who received either neoadjuvant or adjuvant RT and curative intent esophagectomy from 2004 to 2007 were included. A comparison of 5-year relative survival outcome among groups categorized by sex, race, age, histology, and tumor size was performed. Results: A total of 933 patients were evaluated; 636 (69%) and 297 (31%) received RT in neoadjuvant and adjuvant setting respectively. Their overall 5-year relative survival rates were 32.8% (95% CI: 28.7-36.9) and 26.5% (95% CI: 21-32.3) (P=0.058). Patients in the neoadjuvant RT group who underwent curative resection for squamous cell carcinoma (SCC) of EC had an improved 5-year relative survival rate of 43.4% (95% CI: 32.5-53.8) compared to 26.5% (95% CI: 15.4-38.9) measured for the adjuvant RT group (P=0.03). The results further revealed a significant increase in the 5-year relative survival rates for stage T3 and Tx when RT was given in neoadjuvant setting compared to adjuvant RT group (T3 28.5% vs. 20.2%, P=0.011; Tx 46.3% vs. 8.9%, P=0.021). When the patients were grouped according to race, sex or age, or based on the timing of radiation relative to surgery, in the other histological or T stage groups, there were no statistically significant differences in the 5-year survival rates. Conclusions: Compared to adjuvant radiotherapy, neoadjuvant radiotherapy results in a better 5-year relative survival in patients with squamous cell neoplasms and/or T3, Tx stage disease. PMID- 29184688 TI - Age and factors associated with access and time to post-operative adjuvant chemotherapy in colon cancer: a French epidemiological study. AB - Background: Studies have shown the negative prognostic impact of increased time between colectomy and postoperative adjuvant chemotherapy (AC) in colon cancer (CC). Our aim was to investigate the role of age and non-organizational factors on access and time to AC. Methods: All adult patients undergoing surgery for stage II or III CC in the "Region Centre-Val de Loire" in 2013, were selected. Time to AC and socio-demographic factors were collected. Logistic regression modeling was used to identify factors associated with access to AC, and a multivariate analysis performed to identify factors associated with time to AC. Results: Among 404 stage II or III patients who underwent colectomy, 182 (45%; sex ratio 1.5; mean age 67.6 years; range 32-90) received AC. AC patients were younger than those without AC (67.6 vs. 77.9 years) and the difference was even greater for stage III patients (69.0 vs. 82.4). The median time to AC was 48 days, exceeding 42 days in 60% of cases. Living alone, postoperative morbidities, and emergency colectomy were independently associated with increased time to AC. Age and other factors were not associated with delayed AC. Conclusions: Emergency colectomy, postoperative morbidities, and living alone are associated with increased time to AC. Organizational measures to reduce the time to AC are therefore unlikely to have an impact. In contrast, age is not associated with increased time to AC, but to access to AC. Reasons for omitting AC in older patients requires further study. PMID- 29184689 TI - Low-tie IMA and selective D3 lymph node sampling in laparoscopic rectal resection for carcinoma rectum: comparison of surgical and oncological outcomes with the open technique. AB - Background: Level of proximal lymphovascular ligation remains controversial in carcinoma rectum. High-tie inferior mesenteric artery (IMA) claims better lymph node clearance; low-tie IMA minimizes autonomic nerve injury (ANI) and ensures vascularity to anastomosis. Objective of this study is to compare postsurgical complications and oncological clearance in laparoscopic rectal resection (LRR) and open rectal resection (ORR) for carcinoma rectum, with low-tie IMA and selective D3 lymphadenectomy. Methods: Retrospective analysis was done comparing LRR and ORR done with low-tie IMA for carcinoma rectum/rectosigmoid for significant differences (P<0.05) regarding postsurgical complications and histopathology parameters. Results: A total of 118 patients; 48 in LRR group and 70 in ORR group were studied. They were comparable in age, site of lesion and clinical TNM (cTNM) stage. Comorbidities and symptoms requiring upfront surgery were more among ORR. 75% LRR and 55.3% ORR had neoadjuvant chemoradiation (NACRT). Duration of surgery was longer in LRR. Clavien-Dindo grade >3 was similar in two groups. Histopathology characteristics were also comparable; including specimen length, lymph node yield, length of distal margin and pathologic TNM (pTNM) stage. Selective D3 lymphadenectomy was done in 37.5% LRR and 37.14% ORR. And 4.16% in LRR and 4.28% in ORR were had positive IMA root lymph nodes. Conclusions: The post-surgical complications and oncological clearance of LRR done with low-tie IMA and selective D3 lymphadenectomy were found equivalent to ORR. Low-tie IMA without routine splenic flexure mobilisation had no technical issues regarding the anastomosis. PMID- 29184691 TI - Long-term oncologic outcomes of stent as a bridge to surgery versus emergency surgery in malignant left side colonic obstructions: a meta-analysis. AB - Background: The placement of a metallic stent as a bridge to surgery (SBTS) could represents an option for the treatment of left-sided malignant colonic obstruction in centres with adequate skills. Several meta-analyses demonstrated better short-term outcomes after SBTS when compared with emergency surgery (ES); however, some studies reported a higher local recurrence rate. The aim of the present review is to investigate the long-term outcomes of stent bridge to surgery as compared to ES. Methods: A systematic review was performed to retrieve studies comparing long-term oncologic outcomes of SBTS and ES. Local and overall recurrence rate, overall and disease-free survival were retrieved and results were expressed as risk ratios. Results: Seventeen studies and a total of 1,333 patients were included in the analysis. No significant differences were reported in recurrence rate [risk ratio (RR) =1.11; 95% confidence interval (95% CI): 0.84 1.47, P=0.47], 3-year mortality (RR =0.90; 95% CI: 0.73-1.12, P=0.34) and 5-year mortality (RR =1.00; 95% CI: 0.82-1.22, P=0.99). There were no differences among randomized and observational studies. Conclusions: SBTS has similar long-term oncologic outcomes to ES and in centres with appropriate skill should be considered the best treatment option for left-sided malignant colonic obstructions. PMID- 29184690 TI - Correlation of tumor mutational burden and treatment outcomes in patients with colorectal cancer. AB - Background: The Cancer Genome Atlas (TCGA) showed that 16% of colorectal cancers (CRCs) display DNA repair mechanisms and high tumor mutational burden (TMB). Although, there is accumulating evidence of greater benefit of immunotherapy in tumors with high-TMB, its impact on response to chemotherapy is unknown. Methods: In this retrospective cohort study, we investigated the impact of TMB on progression-free survival (PFS) of CRC patients treated at tertiary care oncology clinics who had their tumors profiled by next-generation sequencing (NGS). Low TMB (TMB-L) and intermediate/high TMB (TMB-I/H) were defined as <=5 mutations per base (MB) or >=6 MB, respectively. Results: Seventy-four CRC patients (61 colon and 13 rectal cancers) were identified from the database. In the TMB-L cohort, irinotecan-based chemotherapy treated patients had improved PFS compared to oxaliplatin-based chemotherapy treated patients (11.9 vs. 6.5 months, P<0.001). No difference in PFS was observed between the two treatment cohorts in TMB-I/H group. There was also no difference in time to recurrence in the TMB-L and TMB I/H arms in patients treated with oxaliplatin-based therapy in perioperative setting. Conclusions: TMB-L may be a predictive biomarker in a subset of CRC patients treated with chemotherapy but these results need to confirmed in larger studies. PMID- 29184692 TI - Advanced duodenal neoplasia and carcinoma in familial adenomatous polyposis: outcomes of surgical management. AB - Background: In addition to the presence of neoplasia in the colon and rectum, patients with familial adenomatous polyposis (FAP) may develop numerous polyps and carcinoma within the upper gastrointestinal tract. Methods: The aim of the present paper was to review the incidence advanced duodenal polyposis or cancer and their surgical outcomes. A retrospective review of patients' records from our department was performed. Information was retrieved from a prospective collected data, including clinical (gender, age, family history), endoscopic [association with colorectal cancer (CRC), polyposis severity, age at diagnosis] and surgical management (age, time from the index surgery, type of procedure, morbidity). Duodenal adenomatosis at the time of surgery was classified according to Spigelman stages. Results: In a group of 145 FAP patients, 8 (5.5%) had been surgically treated for duodenal advanced neoplasia [3] or cancer [5]. There were included 2 women and 6 men whose first endoscopic examination and diagnosis of advanced neoplasia/cancer was made at median ages of 47.3 [28-63] and 51.8 years, respectively. Duodenal carcinomas occurred later (55.8 years) when compared to advanced adenomatosis (45.3 years). Three patients were diagnosed due to symptoms, while the others were detected under endoscopic surveillance. Age interval between FAP treatment and duodenal neoplasia diagnosis was 15.3 years [0 47]. All but one patient underwent duodenopancreatectomy (DP). Two from the 7 patients undergoing DP died, one from pulmonary embolism 30 days after surgery and the other from recurrent T4N0 duodenal tumor. Thus, major operative morbidity and mortality were 12.5%. Conclusions: In this single-center Brazilian series of FAP patients: (I) advanced duodenal neoplasia or cancer requiring surgery occurred in 5.5% of patients; (II) when reaching the fifth decade of life, patients should be carefully evaluated to diagnose and treat early lesions; (III) in spite of the technical complexity of DP, operative morbidity is acceptable in experienced hands; and (IV) continuous surveillance is necessary during follow up. PMID- 29184693 TI - Predictors of intermediate-term survival with destination locoregional therapy of hepatocellular cancer in patients either ineligible or unwilling for liver transplantation. AB - Intra-arterial or percutaneous locoregional therapies (LRT) are often employed to maintain potential liver transplant (LT) recipients with hepatocellular carcinoma (HCC) within T2/Milan criteria. Predictors of survival when LRT is used as destination therapy in those who are either ineligible or unwilling for LT remain poorly defined. We evaluated predictors of 3-year survival with destination LRT in a population of cirrhotic patients diagnosed with HCC, presenting within T2 criteria, and either ineligible or unwilling for LT. The cohort surviving 3 years had a significantly lower model for end-stage liver disease (MELD) score at HCC diagnosis (9.7 vs. 11.4, P=0.037) and MELD following initial locoregional therapy (10.7 vs. 13.3, P=0.008) compared to those not surviving three years despite similar demographic, tumor, and treatment variables. LRT as destination therapy results in modest intermediate term survival, with liver function at presentation and immediately following initiation of LRT predicting intermediate survival with this approach. PMID- 29184694 TI - Survivorship after treatment of pancreatic cancer: insights via an Internet-based survivorship care plan tool. AB - Pancreatic cancer survivors face a unique set of challenges in survivorship, yet structured survivorship care planning is lacking in practice. Survivorship care plans (SCPs) are an essential part of quality cancer care and can facilitate the transition following active treatment; the use of SCPs in pancreatic cancer survivors, however, has not been explored. With a convenience sample of 117 pancreatic cancer survivors and proxies who used an Internet-based SCP tool, we examined treatment details, patient-reported outcomes, and survivorship practices. Thirty-one percent of survivors were 2 years or greater from diagnosis with a median current age of 62 years. Most patients had received multimodality therapy (67%): 68%, 86%, and 43% reported surgical intervention, intravenous chemotherapy, and radiation therapy for their pancreatic cancer, respectively. Survivors commonly reported fatigue, cognitive change, neuropathy, pancreatic insufficiency, and chronic radiation dermatitis related to treatment. Most survivors are managed (47%) or co-managed (35%) by an oncology specialist; however, this percentage decreases over time with consequent increase in management by primary care providers alone. Only 5% had previously been offered an SCP. Of the 24 users who responded to a follow-up satisfaction survey, 83% indicated they would share the SCP with their healthcare team although half of respondents felt it should include more information. In all, our results demonstrate that there is a population of pancreatic cancer survivors who exist and seek survivorship support although structured survivorship care planning is lacking in practice. SCPs have a potentially valuable role for these survivors via communication of treatment-related effects and coordination across multidisciplinary healthcare teams. Further development and evaluation of SCPs is needed for this underserved survivor population. PMID- 29184695 TI - Demographic and clinical factors associated with suicide in gastric cancer in the United States. AB - While increased suicidal tendencies among cancer patients have been well documented, there has been no specific examination of suicide and gastric cancer. The purpose of this study is to characterize suicide incidence among patients diagnosed with gastric cancer from 1973 to 2013 and identify variables associated with higher suicide rates. Patients with gastric cancer were identified in the Surveillance, Epidemiology, and End Results (SEER) database of the National Cancer Institute. The study included clinical and demographic data from 1973 to 2013. Standardized mortality ratios (SMRs) and 95% confidence intervals (95% CIs) were calculated. Comparisons with the general US population were based on mortality data collected by the Centers for Disease Control and Prevention's National Center for Injury Prevention and Control using the Web-based Injury Statistics Query and Reporting System. Multivariable logistic regression models generated odds ratios (ORs) to assess factors associated with increased suicide in gastric malignancy. There were 210 suicides for patients with gastric cancer (SMR, 3.21; 95% CI: 2.80-3.67). Female gender (SMR 8.54), White race (SMR 4.08), age <=39 years (SMR 3.06), and age 70-79 years (SMR 2.90), were found to be significant for an increased incidence of suicide compared with the general population. There was not a statistically significant relationship between suicide and marital status, income, mode of radiation therapy, and the role of surgical intervention. Approximately 77% of deaths by suicide occurred within the first year following diagnosis. Female gender, White race, age <=39 years, and age 70-79 years are factors associated with increased risk of suicide in patients with gastric cancer. These results, coupled with further studies and analyses, will be used to formulate a comprehensive suicide risk factor scoring system for screening all cancer patients. PMID- 29184696 TI - Adaptive radiation dose escalation in rectal adenocarcinoma: a review. AB - Total mesorectal excision (TME) after neoadjuvant chemoradiotherapy (CRT) has offered superior control for patients with locally advanced rectal cancer, but can carry a quality of life cost. Fortunately, some patients achieve a complete response after CRT alone without the added morbidity caused by surgery. Efforts to increase fidelity of radiation treatment planning and delivery may allow for escalated doses of radiotherapy (RT) with limited off-target toxicity and elicit more pathological complete responses (pCR) to CRT thereby sparing more rectal cancer patients from surgery. In this review, methods of delivering escalated RT boost above 45-50.4 Gy are discussed including: 3D conformal, intensity-modulated radiotherapy (IMRT), and brachytherapy. Newly developed adaptive boost strategies and imaging modalities used in RT planning and response evaluation such as magnetic resonance imaging (MRI) and positron emission tomography (PET) are also discussed. PMID- 29184697 TI - Clinical presentation, diagnosis, classification and management of peritoneal mesothelioma: a review. AB - Peritoneal mesothelioma (PM) is an uncommon but a serious, and often, fatal primary peritoneal tumour, with increasing incidence worldwide. Conventional systemic chemotherapy, generally based on experience with pleural mesothelioma, usually has disappointing results considering PM as a terminal condition. Patients usually present with non-specific symptoms of abdominal distension and pain making the diagnosis challenging. As PM is confined to the abdomen for all, or much, of its clinical course, a multimodality treatment combining cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has emerged as a new standard of care, and has been reported to achieve promising survival outcomes and local disease control in selected patients with PM. This review updates the presentation, diagnosis, classification and treatment strategies for PM. PMID- 29184699 TI - Pancreatic non-functioning neuroendocrine tumor: a new entity genetically related to Lynch syndrome. AB - Some pancreatic neuroendocrine tumors (P-NETs) are associated with hereditary syndromes. An association between Lynch syndrome (LS) and P-NETs has been suggested, however it has not been confirmed to date. We describe the first case associating LS and P-NETs. Here we report a 65-year-old woman who in the past 20 years presented two colorectal carcinomas (CRC) endometrial carcinoma (EC), infiltrating ductal breast carcinoma, small intestine adenocarcinoma, two non functioning P-NETs and sebomatricoma. With the exception of one P-NET, all these conditions were associated with LS, as confirmed by immunohistochemistry (IHC) and polymerase chain reaction (PCR). LS is caused by a mutation of a mismatch repair (MMR) gene which leads to a loss of expression of its protein. CRC is the most common tumor, followed by EC. Pancreatic tumors have also been associated with LS. Diagnosis of LS is based on clinical criteria (Amsterdam II and Bethesda) and genetic study (MMR gene mutation). The association between LS and our patient's tumors was confirmed by IHC (loss of expression of proteins MLH1 and its dimer PMS2) and the detection of microsatellite instability (MSI) using PCR. PMID- 29184698 TI - Case report: primary acinar cell carcinoma of the liver treated with multimodality therapy. AB - We describe a case of primary acinar cell carcinoma (ACC) originating in the liver in a 54-year-old female, diagnosed following persistent abnormal elevated liver function. Imaging revealed two masses, one dominant lesion in the right hepatic lobe and another in segment IVA. A right hepatectomy was performed to remove the larger lesion, while the mass in segment IVA was unresectable due to its proximity to the left hepatic vein. Immunohistochemical staining showed positivity for trypsin and chymotrypsin. Postoperatively the patient underwent hepatic arterial embolization of the other unresectable lesion followed by FOLFOX chemotherapy. At 20 months from diagnosis the patient is currently under observation with a decreasing necrotic mass and no other disease evident. Based on histology, immunohistochemistry and radiological findings a diagnosis of primary ACC of the liver was made. Genomic assessment of somatic mutations within the patient's tumor was also performed through next generation sequencing and findings were consistent with an acinar malignancy. This case highlights a rare tumor subtype treated with a combination of therapeutic modalities through a multidisciplinary approach. PMID- 29184700 TI - The burden of congenital rubella syndrome in the Philippines: results from a retrospective assessment. AB - Introduction: In line with the regional aim of eliminating rubella and congenital rubella syndrome (CRS), phased introduction of rubella-containing vaccines (RCV) in the Philippines' routine immunization programme began in 2010. We estimated the burden of CRS in the country before widespread nationwide programmatic RCV use. Methods: We performed a retrospective chart review in four tertiary hospitals. Children born between 1 January 2009 and 31 December 2014 and identified as possible CRS cases based on the presence of one or more potential manifestations of CRS documented in hospital or clinic charts were reviewed. Cases that met the clinical case definition of CRS were classified as either confirmed (with laboratory confirmation) or probable (without laboratory confirmation). Cases that did not fulfil the criteria for either confirmed or probable CRS were excluded from the analysis. Results: We identified 18 confirmed and 201 probable cases in this review. Depending on the hospital, the estimated incidence of CRS ranged from 30 to 233 cases per 100 000 live births. The estimated national burden of CRS was 20 to 31 cases per 100 000 annually. Discussion: This is the first attempt to assess the national CRS burden using in country hospital data in the Philippines. Prospective surveillance for CRS and further strengthening of the ongoing measles-rubella surveillance are necessary to establish accurate estimates of the burden of CRS and the impact of programmatic RCV use in the future. PMID- 29184701 TI - Paneth cells in intestinal physiology and pathophysiology. AB - Small intestinal mucosa is characterised by villus forming connective tissues with highly specialised surface lining epithelial cells essentially contributing to the establishment of the intestinal border. In order to perform these diverse functions, spatially distinct compartments of epithelial differentiation are found along the crypt-villus axis, including Paneth cells as a highly specialised cell type. Paneth cells locate in crypts and assist undifferentiated columnar cells, called crypt base columnar cells, and rapidly amplifying cells in the regeneration of absorptive and secretory cell types. There is some evidence that Paneth cells are involved in the configuration and function of the stem cell zone as well as intestinal morphogenesis and crypt fission. However, the flow of Paneth cells to crypt bottoms requires strong Wnt signalling guided by EphB3 and partially antagonised by Notch. In addition, mature Paneth cells are essential for the production and secretion of antimicrobial peptides including alpha defensins/cryptdins. These antimicrobials are physiologically involved in shaping the composition of the microbiome. The autophagy related 16-like 1 (ATG16L1) is a genetic risk factor and is involved in the exocytosis pathway of Paneth cells as well as a linker molecule to PPAR signalling and lipid metabolism. There is evidence that injuries of Paneth cells are involved in the etiopathogenesis of different intestinal diseases. The review provides an overview of the key points of Paneth cell activities in intestinal physiology and pathophysiology. PMID- 29184702 TI - Pharmacological inhibition of diacylglycerol acyltransferase-1 and insights into postprandial gut peptide secretion. AB - AIM: To examine the role that enzyme Acyl-CoA:diacylglycerol acyltransferase-1 (DGAT1) plays in postprandial gut peptide secretion and signaling. METHODS: The standard experimental paradigm utilized to evaluate the incretin response was a lipid challenge. Following a lipid challenge, plasma was collected via cardiac puncture at each time point from a cohort of 5-8 mice per group from baseline at time zero to 10 h. Incretin hormones [glucagon like peptide-1 (GLP-1), peptide tyrosine-tyrosine (PYY) and glucose dependent insulinotropic polypeptide (GIP)] were then quantitated. The impact of pharmacological inhibition of DGAT1 on the incretin effect was evaluated in WT mice. Additionally, a comparison of loss of DGAT1 function either by genetic ablation or pharmacological inhibition. To further elucidate the pathways and mechanisms involved in the incretin response to DGAT1 inhibition, other interventions [inhibitors of dipeptidyl peptidase-IV (sitagliptin), pancreatic lipase (Orlistat), GPR119 knockout mice] were evaluated. RESULTS: DGAT1 deficient mice and wildtype C57/BL6J mice were lipid challenged and levels of both active and total GLP-1 in the plasma were increased. This response was further augmented with DGAT1 inhibitor PF-04620110 treated wildtype mice. Furthermore, PF-04620110 was able to dose responsively increase GLP-1 and PYY, but blunt GIP at all doses of PF-04620110 during lipid challenge. Combination treatment of PF-04620110 and Sitagliptin in wildtype mice during a lipid challenge synergistically enhanced postprandial levels of active GLP-1. In contrast, in a combination study with Orlistat, the ability of PF 04620110 to elicit an enhanced incretin response was abrogated. To further explore this observation, GPR119 knockout mice were evaluated. In response to a lipid challenge, GPR119 knockout mice exhibited no increase in active or total GLP-1 and PYY. However, PF-04620110 was able to increase total GLP-1 and PYY in GPR119 knockout mice as compared to vehicle treated wildtype mice. CONCLUSION: Collectively, these data provide some insight into the mechanism by which inhibition of DGAT1 enhances intestinal hormone release. PMID- 29184703 TI - Effects of commercially produced almond by-products on chemotherapy-induced mucositis in rats. AB - AIM: To determine if almond extracts reduce the severity of chemotherapy-induced mucositis as determined through biochemical, histological and behavioural markers. METHODS: Intestinal mucositis is a debilitating condition characterized by inflammation and ulceration of the gastrointestinal mucosa experienced by cancer patients undergoing chemotherapy. Certain bioactive plant products have shown promise in accelerating mucosal repair and alleviating clinical symptoms. This study evaluated almond extracts for their potential to reduce the severity of chemotherapy-induced mucositis in Dark Agouti rats. Female Dark Agouti rats were gavaged (days 3-11) with either PBS, almond hull or almond blanched water extract at two doses, and were injected intraperitoneally with 5-fluorouracil (5 FU-150 mg/kg) or saline on day 9 to induce mucositis. Burrowing behavior, histological parameters and myeloperoxidase activity were assessed. RESULTS: Bodyweight was significantly reduced in rats that received 5-FU compared to saline-treated controls (P < 0.05). Rats administered 5-FU significantly increased jejunal and ileal MPO levels (1048%; P < 0.001 and 409%; P < 0.001), compared to healthy controls. Almond hull extract caused a pro-inflammatory response in rats with mucositis as evidenced by increased myeloperoxidase activity in the jejunum when compared to 5-FU alone (rise 50%, 1088 +/- 96 U/g vs 723 +/- 135 U/g, P = 0.02). Other extract-related effects on inflammatory activity were minimal. 5-FU significantly increased histological severity score compared to healthy controls confirming the presence of mucositis (median of 9.75 vs 0; P < 0.001). The extracts had no ameliorating effect on histological severity score in the jejunum or ileum. Burrowing behavior was significantly reduced in all chemotherapy-treated groups (P = 0.001). The extracts failed to normalize burrowing activity to baseline levels. CONCLUSION: Almond extracts at these dosages offer little beneficial effect on mucositis severity. Burrowing provides a novel measure of affective state in studies of chemotherapy-induced mucositis. PMID- 29184704 TI - Surgical nuances of circumferential lumbar spondylectomy: A case report and short literature review. AB - Background: Chordomas are uncommon malignant bone tumors that are often minimally symptomatic for several years. By the time they are diagnosed, these lesions are typically large, involve major neural, bony, and vascular structures, and are no longer readily resectable. This leads to a high recurrence rate. Case Description: In this case report, we present a 67-year-old male with nonmechanical axial back pain, neurogenic claudication, and a large mass centered at the L3 level on magnetic resonance imaging consistent with a locally invasive chordoma. The patient underwent surgical resection that required a complete lumbar spondylectomy utilizing a three-stage approach, leading to incomplete tumor excision. The patient's residual postoperative symptoms included paresthesias/numbness in the right anterior thigh and a partial (4/5) right-sided foot drop. At the time of discharge, there were plans for future proton beam therapy. Conclusions: Because of their relative resistance to chemotherapeutic agents, the optimal surgical management of chordomas is gross total en-bloc excision. Unfortunately, this is rarely feasible. PMID- 29184705 TI - Phrenic nerve decompression for the management of unilateral diaphragmatic paralysis - preoperative evaluation and operative technique. AB - Background: Unilateral diaphragmatic paralysis (UDP) can be a very disabling, typically causing shortness of breath and reduced exercise tolerance. We present a case of a surgical decompression of the phrenic nerve of a patient who presented with UDP, which occurred following cervical spine surgery. Methods: The workup for the etiology of UDP demonstrated paradoxical movement on "sniff test" and notably impaired pulmonary function tests. Seven months following the onset of the UDP, he underwent a surgical decompression of the phrenic nerve at the level of the anterior scalene. Results: He noted rapid symptomatic improvement following surgery and reversal of the above noted objective findings was documented. At his 4-year follow-up, he had complete resolution of his clinical symptoms. Repeated physiologic testing of his respiratory function had shown a complete reversal of his UDP. Conclusions: Anatomical compression of the phrenic nerve by redundant neck vasculature should be considered in the differential diagnosis of UDP. Here we demonstrated the techniques in workup and surgical management, with both subjective and objective evidence of success. PMID- 29184706 TI - Cervical intramedullary spinal cord lipoma. AB - Background: Intramedullary, nondysraphic, spinal cord lipomas are rare and account for less than 1% of all spinal cord lesions. Symptoms typically consist of a progressive myelopathy associated with increasing degrees of paralysis (e.g., quadriparesis/plegia, paraparesis/plegia). Case Description: A 39-year-old male, without a history of spinal dysraphism, presented with a progressive spastic quadriparesis. This was attributed to magnetic resonance-documented large intramedullary cervical lipoma. Following partial intramedullary surgical debulking of the lesion, the patient neurologically improved. Conclusion: Partial debulking of a cervical intramedullary lipoma in a patient who originally presented with a severe quadriparesis resulted in significant neurological improvement. Notably, utilization of intraoperative ultrasonography, CO2 laser, and both motor evoked and somatosensory evoked potentials can be helpful during the removal of such lipomas. PMID- 29184707 TI - Hydrocephalus as a rare compilation of vertebrobasilar dolichoectasia: A case report and review of the literature. AB - Background: Vertebrobasilar dolichoectasia (VBD) is a rare disease characterized by significant expansion, elongation, and tortuosity of the vertebrobasilar arteries. Hydrocephalus is a rare compilation of VBD. Case Description: In this study, we report a 68-year-old male presenting with headache, progressive decreased visual acuity, memory loss, imbalance while walking, and episodes of urinary incontinency. The patient was diagnosed with dolichoectasia of basilar artery causing compression of the third ventricular outflow and thus, presenting with hydrocephalus documented with brain computed tomography scan and brain magnetic resonance imaging. The patient underwent surgical operation and ventriculoperitoneal shunt placement. Conclusion: In the case of hydrocephalus or normal pressure hydrocephalous, VBD should be considered as a differential diagnosis. PMID- 29184708 TI - Solitary Aggregatibacter aphrophilus tectal abscess in an immunocompetent patient. AB - Background: A solitary abscess involving the tectum, specifically by Aggregatibacter aphrophilus, is an extremely rare condition with no known reported cases to date. Case Description: Here, we present a case of isolated solitary midbrain tectum abscess in an immunocompetent 28-year-old male who was empirically diagnosed as a primary tectal tumor at an outside hospital where he also underwent placement of a ventriculoperitoneal shunt (VPS) for obstructive hydrocephalus. Eight weeks later he was readmitted with a VPS infection. He was transferred to our institution where the VPS was removed and he was started on broad-spectrum antibiotics. Cerebrospinal fluid (CSF) culture revealed A. aphrophilus. All other workup was negative for infectious etiologies. The tectal lesion completely resolved after 15 weeks of intravenous ceftriaxone without surgical aspiration. Conclusion: We suggest that an empiric diagnosis of tectal glioma should be made with caution for a ring-enhancing mass. CSF should be routinely cultured at the time of operative diversion if abscess is a possibility. PMID- 29184709 TI - Gamma knife radiosurgery for cerebellopontine angle epidermoid tumors. AB - Background: Intracranial epidermoid tumors are commonly found in the cerebellopontine angle where they usually present with either trigeminal neuralgia or hemifacial spasm. Radiosurgery for these tumors has rarely been reported. The purpose of this study is to assess the safety and clinical outcome of the treatment of cerebellopontine epidermoid tumors with gamma knife radiosurgery. Methods: This is a retrospective study involving 12 patients harboring cerebellopontine angle epidermoid tumors who underwent 15 sessions of gamma knife radiosurgery. Trigeminal pain was present in 8 patients and hemifacial spasm in 3 patients. All cases with trigeminal pain were receiving medication and still uncontrolled. One patient with hemifacial spasm was medically controlled before gamma knife and the other two were not. Two patients had undergone surgical resection prior to gamma knife treatment. The median prescription dose was 11 Gy (10-11 Gy). The tumor volumes ranged from 3.7 to 23.9 cc (median 10.5 cc). Results: The median radiological follow up was 2 years (1-5 years). All tumors were controlled and one tumor shrank. The median clinical follow-up was 5 years. The trigeminal pain improved or disappeared in 5 patients, and of these, 4 cases stopped their medication and one decreased it. The hemifacial spasm resolved in 2 patients who were able to stop their medication. Facial palsy developed in 1 patient and improved with conservative treatment. Transient diplopia was also reported in 2 cases. Conclusion: Gamma knife radiosurgery provides good clinical control for cerebellopontine angle epidermoid tumors. PMID- 29184711 TI - Adult sacrococcygeal teratoma with coccygectomy: A case report with a review of the literature. AB - Background: Saccrococcygeal teratomas (SCT) are derived from embryonic germ cell layers. They frequently present at the base of the coccyx within the pelvis. While these tumors are common in children, they are exceedingly rare in adults. In adults, a majority of these tumors are intrapelvic and associated with a low risk of malignant transformation. Therefore, this contributes to a good prognosis following resection of mostly benign lesions. Case Description: An adult female with chronic pelvic pain presented with a sacral teratoma. She failed conservative treatment and underwent a coccygectomy with an en-bloc excision of the tumor. Microscopic histological analysis showed no evidence of immature or malignant elements, confirming the diagnosis of a mature, benign, cystic SCT. Conclusions: Mature SCTs in adults are rare malignant lesions. In this case, the patient was cured following primary surgical excision requiring en-bloc coccygectomy. PMID- 29184710 TI - Retrospective study of 229 surgically treated patients with brain metastases: Prognostic factors, outcome and comparison of recursive partitioning analysis and diagnosis-specific graded prognostic assessment. AB - Background: Metastases are the most frequent tumors in the brain. Most often used scoring systems to predict the outcome are the RPA (Recursive Partitioning Analysis) classification and the DS-GPA (Diagnosis-Specific Graded Prognostic Assessment) score. The goal of our study was to determine prognostic factors which influence outcome in patients who undergo surgery for brain metastases and to compare different outcome scores. Methods: Two hundred and twenty-nine patients who underwent surgery for brain metastases in our institution between January 2005 and December 2014 were included in the study. Patient data were evaluated retrospectively. Results: The mean survival time was 19.2 months (median survival time, MST: 8 months), for patients with a single metastasis (n = 149) 17.6 months (MST: 8 months), and for patients with multiple metastases (n = 80) 17.9 months (MST: 6 months). Significant influence on MST had age <65 years (9 vs. 5 months, P = 0.002), female sex (10 vs. 6 months, P < 0.001), RPA Class I and II (11 vs. 4 months, P < 0.001), Karnofsky score >70% (11 vs. 4 months, P < 0.001), and postoperative radiotherapy (8 vs. 5 months, P < 0.002). To evaluate the diagnostic power of DS-GPA and RPA score in respect of survival, two Cox regressions were modeled, where the RPA classification showed a better predictive power. Conclusion: Favorable factors for prolonged survival were KPS >70%, RPA Class I and II, age <65 years, female sex, a DS-GPA Score of 2.5-3 and 3.5-4, and adjuvant radiotherapy. The RPA Classification was more accurate in predicting the outcome than the DS-GPA score. PMID- 29184712 TI - Asymmetric neuromodulation of motor circuits in Parkinson's disease: The role of subthalamic deep brain stimulation. AB - Whereas hemispheric dominance is well-established for appendicular motor control in humans, the evidence for dominance in axial motor control is still scarce. In Parkinson's disease (PD), unilateral (UL) onset of appendicular motor symptoms corresponds with asymmetric neurodegeneration predominantly affecting contralateral nigrostriatal circuits. Disease progression yields bilateral and axial motor symptoms but the initial appendicular asymmetry usually persists. Furthermore, there is evidence for hemispheric dominance for axial motor dysfunction in some of these patients. Dopaminergic medications improve appendicular symptoms but can also produce motor complications over time. Once these complications develop, bilateral (BL) deep brain stimulation (DBS) of the subthalamic nuclei (STN) can significantly improve appendicular symptoms while reducing medication doses and motor complications. Conversely, axial motor symptoms remain a significant source of disability, morbidity, and mortality for patients with PD. These axial symptoms do not necessarily improve with dopaminergic therapy, might not respond, and could even worsen after BL-DBS. In contrast to medications, DBS provides the opportunity to modify stimulation parameters for each cerebral hemisphere. Identical, BL-DBS of motor circuits with hemispheric dominance in PD might produce overstimulation on one side and/or understimulation on the other side, which could contribute to motor dysfunction. Several studies based on asymmetry of appendicular motor symptoms already support an initial UL rather than BL approach to DBS in some patients. The response of axial motor symptoms to UL versus BL-DBS remains unclear. Nonetheless, UL-DBS, staged BL-DBS, or asymmetric programming of BL-DBS could also be considered in patients with PD. PMID- 29184714 TI - Clinical significance of thickened sphenoid sinus mucosa in Rathke's cleft cyst. AB - Background: To determine the clinical significance of thickening of the sphenoid sinus mucosa (TSSM) in Rathke's cleft cyst (RCC). Methods: We retrospectively reviewed patients with pituitary lesions. A total of 99 patients, who underwent surgery of pituitary lesions between 2008 and 2015, were analyzed to evaluate the clinical significance of TSSM using magnetic resonance imaging. The patients with TSSM were evaluated for their characteristics. Results: Of the 99 operations, 15 patients with paranasal sinusitis, direct invasion to the sellar floor, and/or a history of transsphenoidal surgery were excluded. There were 51 pituitary adenomas (PAs), 18 RCCs, and 15 other tumors. TSSM was observed in 6 patients (7.1%). Pathologies included 3 RCCs (16.7%), 1 PA (2.0%), and 2 other lesions. Three RCCs were especially analyzed. The pituitary dysfunction was found in all 3 patients with TSSM, whereas that was noted in 2 of 15 patients (13.3%) without TSSM. The sensitivity was 60%, specificity was 86.7%, and the positive predictive value was 100%. There was no significant difference in the age, thickness of TSSM, symptoms, and squamous metaplasia between patients with and without TSSM. Conclusions: TSSM occurs more frequently in RCCs than in PAs. TSSM can potentially suggest hypopituitarism in RCCs. The surgical and/or endocrinological interventions are required for preventing further endocrine deterioration. PMID- 29184713 TI - Posterior atlantoaxial fusion using a C2 transverse foramen-penetrating screw: A technical note. AB - Background: Although recent development of screw instrumentation techniques for rigid fixation of the atlantoaxial joint has increased surgical options, patients in whom screws of any type cannot be safely placed are sometimes encountered. We present a unique surgical technique for C1-2 transarticular screw placement utilizing a novel trajectory. Methods: A 35-year-old male with a history of Down's syndrome and cognitive dysfunction with hyperkinesis spontaneously developed rapid onset of tetraparesis and gait disturbance. Radiographs of the cervical spine revealed atlantoaxial subluxation (AAS) that could not be reduced. Computed tomography (CT) of the head showed multiple subacute cerebral infarctions in the territory of the right vertebral artery (VA). Three dimensional CT angiography of the craniovertebral junction additionally confirmed right VA occlusion at the C2/3 level, a left C2 origin of the posterior inferior cerebellar artery, and hypoplasia of the bilateral C2 pedicles/C2 lamina. Because traditional screw-placement was not feasible, we performed a unique atlantoaxial fusion utilizing a C2 transverse foramen-penetrating screw with iliac bone grafting performed under neuronavigation. Results: The postoperative course was uneventful, and the patient regained the ability to ambulate, returning to his previous level of function. The CT of the cervical spine 12 months postoperatively showed rigid bony C1-C2 fusion, without recurrence of stroke. Conclusion: We introduced a novel C1-C2 transarticular screw-placement technique in which the trajectory went through the ipsilateral VA foramen due to already extent VA occlusion. PMID- 29184715 TI - Unusual case of hemangioblastoma of the cerebellopontine angle. AB - Background: Hemangioblastomas are the most common primary tumor of the posterior fossa. There are few cases of hemangioblastoma of the cerebellopontine angle (CPA). When present in this location, hemangioblastoma presents a diagnostic challenge as its imaging findings closely resemble those of vestibular schwannoma (VS), which is much more common in the CPA. Case Description: We report the case of a 42-year-old man presenting with vertigo and diplopia found to have a CPA tumor with imaging resembling VS. He underwent retrosigmoidal resection of his tumor, which was found to be a hemangioblastoma. Conclusion: Hemangioblastoma, though rare in the CPA, should be considered in the differential diagnosis of CPA tumors. PMID- 29184716 TI - Refractory intracranial hypertension in traumatic brain injury: Proposal for a novel score to assess the safety of lumbar cerebrospinal fluid drainage. AB - Background: Cerebrospinal fluid (CSF) drainage via ventricular puncture is an established therapy of elevated intracranial pressure (ICP). In contrast, lumbar CSF removal is believed to be contraindicated with intracranial hypertension. Methods: We investigated the safety and efficacy of lumbar CSF drainage to decrease refractory elevated ICP in a small cohort of patients with traumatic brain injury (TBI). A score (0-8 points) was used to assess computed tomography (CT) images for signs of herniation and for patency of the basal cisterns. All patients received lumbar CSF drainage either as a continuous drainage or as a single lumbar puncture (LP). Type and method of CSF drainage, mean ICP 24 h prior and after CSF removal, and adverse events were documented. Outcome was assessed after 3 months (with dichotomized Glasgow outcome scale). Results: Eight patients were evaluated retrospectively. n = 5 suffered a moderate, n = 2 a severe TBI (one Glasgow coma score not documented). The CT score was >=5 in all patients prior to LP and decreased after puncture without clinical consequences in two patients. The amount of CSF removal did not correlate with score changes (P = 0.45). CSF drainage led to a significant reduction of mean ICP (from 22.3 to 13.9 mmHg, P = 0.002). Continuous drainage was more effective than a single LP. Three of eight patients reached a favorable outcome. Conclusions: Lumbar CSF removal for the treatment of intracranial hypertension is effective and safe, provided the basal cisterns are discernible, equivalent to >=5 points in the proposed new score. The score needs further validation. PMID- 29184717 TI - Intraventricular hemorrhage possibly extending from an infratentorial subdural hematoma via a perforated suprapineal recessus in a full-term neonate. AB - Background: Although intraventricular hemorrhage (IVH) is very rarely reported in full-term neonates, it may occur in children with perinatal trauma, asphyxia, and coagulation disorders, and may originate in the choroid plexus and residual subependymal germinal matrix layer. Case Description: We present the case of a full-term baby with IVH. She had no perinatal problems or coagulation disorders. Sagittal views of neuroimages demonstrated that the IVH possibly extended from a subdural hemorrhage (SDH) in the infratentorial area via a perforated suprapineal recessus. This was barely visible on a conventional axial view of a computed tomographic scan. Conclusion: When the etiopathogenesis of IVH in a full-term baby with an uncomplicated delivery cannot be clearly defined, multi-directional and multi-modal neuroimaging may be useful. PMID- 29184718 TI - Three consecutive neurotomies in one patient for the treatment of spastic hemiplegia: Spinal, median, and foot toes common flexor. AB - Background: Neurotomies were one of the first procedures performed in the field of functional neurosurgery. Microstimulators and microscopes facilitate the performance of neurotomies to treat focal spasticity. This report shows how three different consecutive neurotomies were performed in one patient with chronic left upper/lower extremity spasticity. Case Description: A 65-year-old male with intractable epilepsy underwent a right temporal lobectomy for seizure control. Postoperatively, he developed left upper/lower extremity spasticity attributed to a postoperative right internal capsule infarct. The severe spasticity persisted despite the administration of conventional drugs, rehabilitation efforts, and botulinic toxin injections. Three sequential selective neurotomies (e.g., spinal, median, and foot common flexor nerves) were next performed. Postoperatively, the neurotomies resulted in significant symptomatic long-term improvement, 6 years after spinal neurotomy, 7 years after median neurotomy, and 9 years after common flexor neurotomy. Spasticity scores diminished from 4 to 0 points on the Ashworth scale and from 4 to 0 points on the Held-Tardieu scale for each muscular region. Conclusion: Multiple regional neurotomies were effective in the management of left-sided postoperative spasticity in a patient who underwent a temporal lobectomy for seizure control with a resultant postoperative right internal capsule infarct. PMID- 29184719 TI - Diabetes and morbid obesity are associated with higher reoperation rates following microvascular decompression surgery: An ACS-NSQIP analysis. AB - Background: Microvascular decompression (MVD) is the preferred treatment for refractory trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia. Despite its high rate of success, MVD carries risk of complications. In this study, we examine outcomes following MVD and identify risk factors associated with adverse outcomes. Methods: A review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was performed with CPT code 61458 queried between 2007 and 2014. Demographics, preoperative comorbidities, and 30-day outcomes were analyzed. Univariate and multivariate regression analyses were performed to identify predictors of reoperation and adverse events. Results: Five hundred and six craniotomies were studied. Nineteen (5.5%) instances of 30-day readmission were reported, with 14 (2.8%) patients returning to the operating room. No instances of death or hemorrhage requiring operation were reported. Morbid obesity (body mass index >40) (P = 0.030) and diabetes (P = 0.017) were associated with risk of reoperation. Age, operative time, and indication for surgery were not associated with significant differences in adverse events. Conclusions: MVD is a common and effective procedure with a relatively safe profile and low 30-day risk of reoperation. Advanced age is not associated with worse outcomes. Obesity and diabetes, however, are associated with increased risk of reoperation and may warrant additional precautions. PMID- 29184721 TI - Facial Contouring Surgery-Malarplasty. AB - Supplemental Digital Content is available in the text. PMID- 29184720 TI - Risk factors for wound complications following spine surgery. AB - Background: Wound complications, including surgical site infections (SSIs) and wound dehiscence, are among the most common complications following spine surgery often leading to readmission. The authors sought to identify preoperative characteristics predictive of wound complications after spine surgery. Methods: The American College of Surgeons National Surgical Quality Improvement Program database for years 2012-2014 was reviewed for patients undergoing spine surgery, defined by the Current Procedural Terminology codes. Forty-four preoperative and surgical characteristics were analyzed for associations with wound complications. Results: Of the 99,152 patients included in this study, 2.2% experienced at least one wound complication (superficial SSI: 0.9%, deep SSI: 0.8%, organ space SSI: 0.4%, and dehiscence: 0.3%). Multivariate binary logistic regression testing found 10 preoperative characteristics associated with wound complications: body mass index >=30, smoker, female, chronic steroid use, hematocrit <38%, infected wound, inpatient status, emergency case, and operation time >3 hours. A risk score for each patient was created from the number of characteristics present. Receiver operating characteristic curves of the unweighted and weighted risk scores generated areas under the curve of 0.701 (95% CI: 0.690-0.713) and 0.715 (95% CI: 0.704-0.726), respectively. Patients with unweighted risk scores >7 were 25-fold more likely to develop a wound complication compared to patients with scores of 0. In addition, mortality rate, reoperation rate, and total length of stay each increased nearly 10-fold with increasing risk score. Conclusion: This study introduces a novel risk score for the development of wound dehiscence and SSIs in patients undergoing spine surgery, using new risk factors identified here.

PMID- 29184723 TI - Patient-Reported Outcomes following Split-Face Injection of 2 Volumizing Fillers in the Upper Cheeks. AB - Background: Patient-reported outcomes are important measures when assessing the efficacy of aesthetic procedures. Objective: To compare outcomes between 2 volumizing hyaluronic acid fillers. Materials and Methods: Subjects with moderate to-severe volume loss in the cheeks were randomized in a split-face design to malar enhancement with Cohesive Polydensified Matrix 26 mg/ml HA (CPM-26) and Vycross 20 mg/ml HA (VYC-20). The same injection technique and injection volume were applied for both sides of the face. Anesthetics, overcorrection, and touch ups were not permitted. Blinded subjects assessed aesthetic improvements using the Global Aesthetic Improvement Scale and treatment satisfaction by confirming their willingness to repeat treatment or recommend it to friends. Follow-up was 18 months. Results: A total of 45 subjects received a single 2 mL injection of CPM-26 on one side and VYC-20 on the contralateral side of the face. The proportion of subjects reporting improvement on the Global Aesthetic Improvement Scale compared with baseline for CPM-26 and VYC-20 was 97.7% and 88.6%, respectively, at 3 months, 73.8% and 71.1% at 12 months, and 61.0% and 56.7% at 18 months. Treatment satisfaction was high, with the majority of subjects stating that they would repeat treatment and recommend it to friends, but at each time point, a higher proportion of subjects was more satisfied with the CPM-26-treated side of the face. Conclusions: In this first direct comparison of CPM-26 and VYC 20, the majority of subjects were satisfied with both treatments throughout the study. Patient-reported outcome measures identified a trend in favor of CPM-26. PMID- 29184724 TI - An Algorithmic Approach to Operative Management of Complex Pediatric Dog Bites: 3 Year Review of a Level I Regional Referral Pediatric Trauma Hospital. AB - Background: Incidence of dog bites continues to rise among the pediatric population and serves as a public health threat for the well-being of children. Plastic surgeons are at the forefront of initial management and eventual outcome of these devastating injuries. This study set out to determine the nature of dog bite injuries treated over a 3-year period at a large level 1 pediatric trauma center. Methods: A retrospective review of emergency room records of all pediatric patients (age, 0-18 years old) who sustained dog bites between January 2012 and December 2014 were gathered. All details about age of patient, location and severity of dog bites, type of dog breed, antibiotics given, and emergency versus operative treatment were recorded and analyzed. Results: One hundred eight patients aged 5 months to 18 years old were treated in the emergency department after suffering dog bite injuries during the study period. The highest incidence of dog bites occurred in preschool children. The mean age for patients who required operative repair was lower than the mean age for patients who underwent primary closure in the emergency department. The location of injury was most commonly isolated to the head/neck region. Of the 56 cases that had an identified dog breed, pit bulls accounted for 48.2% of the dog bites, and 47.8% of pit bull bites required intervention in the operating room. Conclusion: Children with large dog bite injuries require more immediate care in a level 1 pediatric trauma hospitals in order to optimize their hospitalization course and eventual outcome.

PMID- 29184727 TI - Preliminary Study of PGA Fabric for Seromas at Latissimus Dorsi Flap Donor Sites. AB - Background: Seroma formation is a major complication following latissimus dorsi (LD) flap transfer for breast reconstruction. We implanted a nonwoven polyglycolic acid (PGA) fabric-a biodegradable polymer-in the LD flap donor site and examined its effect on postoperative seroma formation and resolution in a comparative study on 38 patients undergoing primary 1-stage breast reconstruction by LD flap. Method: A PGA treatment group had a PGA fabric placed in the donor wound (PGA group, n = 20), whereas a second group was treated with standard donor site closure (control group, n = 18). The incidence of seromas was comparable between the groups. Result: There was a significant reduction in aspiration volume by needle aspiration after drain removal (P < 0.05) and in the time until seroma resolution (P < 0.01) in the PGA group compared with the control group. Conclusion: These results indicate that application of PGA at the LD donor site is useful in controlling postoperative seromas. PMID- 29184728 TI - DIEP Flap Breast Reconstruction in Patients with Breast Ptosis: 2-Stage Reconstruction Using 3-Dimensional Surface Imaging and a Printed Mold. AB - Background: Autologous breast reconstruction can be performed for breasts with ptosis to a certain extent, but if patients desire to correct ptosis, mastopexy of the contralateral breast is indicated. However, accurate prediction of post mastopexy breast shape is difficult to make, and symmetrical breast reconstruction requires certain experience. We have previously reported the use of three-dimensional (3D) imaging and printing technologies in deep inferior epigastric artery perforator (DIEP) flap breast reconstruction. In the present study, these technologies were applied to the reconstruction of breasts with ptosis. Methods: Eight breast cancer patients with ptotic breasts underwent two stage unilateral DIEP flap breast reconstruction. In the initial surgery, tissue expander (TE) placement and contralateral mastopexy are performed simultaneously. Four to six months later, 3D bilateral breast imaging is performed after confirming that the shape of the contralateral breast (post-mastopexy) is somewhat stabilized, and a 3D-printed breast mold is created based on the mirror image of the shape of the contralateral breast acquired using analytical software. Then, DIEP flap surgery is performed, where the breast mold is used to determine the required flap volume and to shape the breast mound. Results: All flaps were engrafted without any major perioperative complications during both the initial and DIEP flap surgeries. Objective assessment of cosmetic outcome revealed that good breast symmetry was achieved in all cases. Conclusions: The method described here may allow even inexperienced surgeons to achieve reconstruction of symmetrical, non-ptotic breasts with ease and in a short time. While the requirement of two surgeries is a potential disadvantage, our method will be particularly useful in cases involving TEs, i.e., delayed reconstruction or immediate reconstruction involving significant skin resection. PMID- 29184729 TI - Combined Tongue Flap and Deepithelialized Advancement Flap for Thick Lower Lip Reconstruction. AB - We repaired a long horizontal defect in the lower lip caused by the resection of squamous cell carcinoma by reconstructing the white lip with a V-Y advancement flap and vermilion with a tongue flap. During this procedure, we deepithelialized the V-Y flap, lifted the upper margin of the flap and sutured it to the remaining upper margin of the lip, and then covered it with the tongue flap, resulting in the successful reconstruction of a thick lip. There were no postoperative complications in articulation or swallowing. This novel procedure is a simple method to aesthetically and functionally reconstruct a thick lower lip. PMID- 29184730 TI - Outcomes Comparison for Microsurgical Breast Reconstruction in Specialty Surgery Hospitals Versus Tertiary Care Facilities. AB - Background: Postoperative monitoring is crucial in the care of free flap breast reconstruction patients. Tertiary care facilities (TCFs) provide postoperative monitoring in an ICU after surgery. Specialty surgery hospitals (SSHs) do not have ICUs, but these facilities perform free flap breast reconstruction as well. Are outcomes comparable between the 2 facilities in terms of flap reexploration times and overall success? Methods: Retrospective study including 163 SSH and 157 TCF patients. Primary predictor was facility in which the procedure was performed. Secondary predictors included operative, demographic, and comorbidity data. Primary outcomes were flap take back rate and flap failures. Secondary outcomes were total time from adverse event noticed in the flap to returning to the operating room (OR) and total time from decision made to return to the OR to returning to the OR (decision made). Tertiary outcomes were length of stay, operative times, and blood loss. Results: Patients at the TCF were generally less healthy than SSH patients. Salvage rates and failure rates were similar between the 2 institutions. Adverse event noticed and decision made times did not differ between the 2 facilities. Overall flap success rate was 98.22% at SSH and 98.81% at TCF. No primary or secondary predictors had a significant correlation with increased odds for flap failure. Conclusion: SSHs can offer similar outcomes in free flap breast reconstruction with just as effective clinical response times to endangered flaps as found in a TCF. However, surgery at an SSH may best be reserved for healthier patients. PMID- 29184731 TI - Tracheocutaneous Fistula Closure with Turnover Flap and Polydioxanone Plate. AB - An alternative surgical treatment is proposed for closure of tracheocutaneous fistulas. The authors present a new technique for reconstruction of persistent tracheocutaneous fistula resultant from temporary tracheostomy. The single-stage closure under local anesthesia involves a fistulous tract turnover flap with a perforated 0.15 mm polydioxanone plate between the flap and the subcutaneous closure. This article presents 3 cases of persistent tracheocutaneous fistula treated by this method. At follow-up examination after follow-up, no recurrent fistula formation had occurred, and no respiratory deformity was present. PMID- 29184732 TI - Depressive Symptoms among Plastic Surgery Residents. AB - Background: A literature review did not reveal any study investigating the prevalence of depression among plastic surgery residents. Methods: We conducted a cross-sectional mail survey and included all Saudi Plastic Surgery residents in our local program in Saudi Arabia. The Beck Depression Inventory II was used. Results: The inventory showed that mild, moderate, and severe depressive symptoms were prevalent in 20.6%, 38.2%, and 11.8%, respectively. Junior residents were more prone to depression. Conclusions: The high prevalence rate of depression among plastic surgery residents is alarming, and further studies are warranted. The problem has received no attention in the plastic surgery literature.

AB - Background: Surgical delay remains a common method for improving flap survival. However, the optimal surgical technique has not been determined. In this article, we compare flap perfusion, viable surface area, and flap contraction of 2 surgical delay techniques. Methods: Male Sprague-Dawley rats were divided into 3 groups. In the incisional surgical delay group (n = 9), a 9 * 3 cm dorsal flap was incised on 3 sides without undermining, leaving a cranial pedicle. In the bipedicle surgical delay group (BSD, n = 9), a 9 * 3 cm dorsal flap was incised laterally and undermined, leaving cranial and caudal pedicles. Control group (n = 16) animals did not undergo a delay procedure. Ten days following surgical delay, all flaps for all groups were raised, leaving a cranial pedicle. A silicone sheet separated the flap and the wound bed. On postoperative day (POD) 7, viable surface area was determined clinically. Contraction compared to POD 0 was measured with ImageJ software. Perfusion was measured with Laser Doppler Imaging. The Kruskal-Wallis with Dunn's multiple comparisons test was performed for group comparisons. Results: BSD preserved significantly more viable surface area on POD 7 (13.7 +/- 4.5 cm2) than Control (8.7 +/- 1.8 cm2; P = 0.01). BSD also showed significantly less contraction (21.0% +/- 13.5%) than Control (45.9% +/- 19.7%; P = 0.0045). BSD and incisional surgical delay showed significantly increased perfusion compared with Control on POD 0 (P = 0.02 and 0.049, respectively), which persisted on POD 3. This trend resolved by POD 7. Conclusion: BSD showed improved early perfusion, increased viable surface area, and reduced contraction compared to control, suggesting that BSD is the superior flap design for preclinical modeling. PMID- 29184735 TI - Association of High-Volume Surgeons Working in High-Volume Hospitals with Cost of Free Flap Surgeries. AB - Background: We examined the associations of surgeon and hospital volume with total cost, length of stay (LOS), and cost per day for free tissue transfer (FTT) surgeries. Evidence demonstrates a higher likelihood of success for FTT in higher volume hospitals. Little, however, is known about volume-outcome associations for surgical costs and LOS. We hypothesized that higher provider volume is associated with lower cost and shorter LOS. Methods: Using Taiwan's national data (2001 2012), we conducted a retrospective cohort study of all adults 18-64 years of age who underwent FTT during the study period. We used hierarchical regression modeling for our analyses. Our 3 outcome variables were total cost of FTT surgery, LOS in hospital, and cost per day. Results: Except for functional muscle flap, in which LOS was 12 days shorter in high-volume compared with low-volume hospitals (P = 0.017), no association between hospital volume and LOS was found. Contrary to our hypothesis, our results for all FTT cases demonstrate positive associations of medium-volume hospitals (OR = 1.31; CI, 1.11-1.55) and high volume surgeons (OR = 1.16; CI,1.03-1.32) with total cost and cost per day, respectively. The interactions of hospital volume and surgeon volume show that in medium- and high-volume hospitals, surgeons with the highest volume had the lowest predicted cost per day among hospitals in that category; but all differences in cost were small. Conclusions: There were no substantial variations based on different hospital or surgeon volume in LOS, total cost, or cost per day for FTT operations performed in Taiwan. PMID- 29184736 TI - The Reconstruction of the Donor Site of DP Flap Using Thoracodorsal Artery Perforator Flap. AB - We performed a new procedure for reconstruction of donor site of a deltopectoral (DP) flap. A 58-year-old man presented with a wide subcutaneous abscess, which was caused by acute mandibular osteomyelitis due to dental caries. On admission, the patient received a neck incision for drainage. However, necrosis of the neck skin was observed after drainage. The patient had an 8 * 10 cm skin and soft tissue defect, which we covered with a DP flap (15 * 7 cm). The DP flap donor site was reconstructed using a 16 * 8 cm pedicled thoracodorsal artery perforator (TDAP) flap. There was no flap necrosis, abscess formation, or scar contracture of the DP region. Debulking of the TDAP flap was not required. The pedicled TDAP flap is useful for the reconstruction of the donor site of DP flap. In this report, we describe our operative procedure. PMID- 29184737 TI - The Idea of Beauty and Its Biases: Critical Notes on the Aesthetics of Plastic Surgery. AB - Two biases affect the idea of beauty often embodied in aesthetic surgery. The first one is that the living body is the sum of different parts; the second one claims that beauty results from the sum of beautiful elements. Taken together, these 2 biases explain most of the aesthetic surgery procedures, in which a localized improvement is supposed to impact on the whole body image. In this article, I put into question these 2 problematic assumptions, showing that Western and Eastern aesthetics, on one side, and philosophical reflections, on the other side, support a different conception of beauty. In particular, an alternative idea that opens to authenticity and imperfection and focuses on the living body rather than on the mere anatomical surface is proposed here as a more adequate concept of beauty for aesthetic surgery. PMID- 29184738 TI - Nasal Duplication Combined with Cleft Lip and Palate: Surgical Correction and Long-Term Follow-Up. AB - Background: Diprosopus dirrhinus, or nasal duplication, is a rare entity of partial craniofacial duplication. Methods: The case we present is the first report of diprosopus dirrhinus associated with complete cleft lip and palate. The baby was born in Cambodia at full term by normal vaginal delivery with no significant perinatal and family history. Physical examination revealed significant facial deformity due to the duplicated nose and the left complete cleft lip/palate on the right subset. Results: There were 4 nostrils; both medial apertures including the cleft site were found to be 10-15 mm deep cul-de-sac structures without communication to the nasopharynx. The upper third of the face was notable for hypertelorism with a duplication of the soft-tissue nasion and glabella. Between the 2 nasal dorsums, there was a small cutaneous depression with a lacrimal fistula in the midline. Surgical treatment included the first stage of primary lip and nose repair and the second stage of palatoplasty. Conclusions: The patient was followed up at the age of 10 years showing satisfactory results for both aesthetic and functional aspects. Further management in the future will be required for the hypertelorism and nasal deformity. PMID- 29184739 TI - Review of 494 Consecutive Breast Augmentation Patients: System to Improve Patient Outcomes and Satisfaction. AB - Background: Breast augmentation continues to be one of the most common surgical procedures performed by plastic surgeons. As implant options expand, controlling the numerous variables required for a successful result will prove increasingly challenging. The purpose of this study was to outline specific steps that can be taken during the patient consultation and during surgery to decrease complications and improve overall patient satisfaction and patient outcomes. Methods: A retrospective review of 494 consecutive patients who underwent primary augmentation mammaplasty performed by a single surgeon was undertaken. Surgical outcomes were recorded and compared with previously published results. Patient satisfaction was measured using the BREAST-Q Augmentation Module. Results: Patients were followed for an average of 6 months (range, 0-45 months). Of the 494 patients, 1.3% developed capsular contracture. Other complications included 0.6% asymmetry, 0.4% malposition, 0.2% hematoma, and 0.2% rippling. The median BREAST Q score for the patient's overall satisfaction with outcome was 86%. The median BREAST Q score for patient's satisfaction with the plastic surgeon, medical team, and office staff was 100% in each case. The median score for psychological well-being, physical well-being, and sexual well-being was 100%, 90%, and 88%, respectively. Conclusions: The system outlined in this study showed very low rates of complications and high scores for patient satisfaction. Following a system like this will become increasingly important as breast augmentation continues to become more popular, implant options continue to expand, and social media continues to be used by patients to share surgical experiences. PMID- 29184740 TI - Can Friedberg's Triad Solve Persistent Anesthesia Problems? Over-Medication, Pain Management, Postoperative Nausea and Vomiting. AB - Friedberg's Triad is (1) measure the brain; (2) preempt the pain; (3) emetic drugs abstain. Persistent anesthesia problems include over- and under-medication, postoperative pain management, and postoperative nausea and vomiting. Inspired by Vinnik's diazepam-ketamine paradigm, Friedberg's propofol ketamine paradigm was first published in 1993. The 1997 addition of the bispectral (BIS) index brain monitor made the propofol ketamine paradigm numerically reproducible. The 1998 addition of the frontalis electromyogram (EMG) as a secondary trend to the BIS transformed the time-delayed BIS monitor into a real-time, extremely useful device. Before BIS monitoring, anesthesiologists only had heart rate (HR) and blood pressure (BP) changes to guide depth of anesthesia. Not surprisingly, the American Society of Anesthesiologists' Awareness study showed no HR or BP changes in half of the patients experiencing awareness with recall. HR and BP changes may only reflect brain stem signs while consciousness and pain are processed at higher, cortical brain levels. BIS/electromyogram measurement can accurately reflect propofol effect on the cerebral cortex in real time. Although propofol requirements can vary as much as a hundred-fold, titrating propofol to 60 < BIS < 75 with baseline electromyogram assures every patient will be anesthetized to the same degree and allows more scientific analysis of outcomes. Numerous publications are cited to support the author's 25-year clinical experience. Over that period, no office-based, cosmetic surgery patients were admitted to the hospital for unmanageable pain or postoperative nausea and vomiting. Friedberg's Triad appears to solve persistent anesthesia problems. PMID- 29184741 TI - Psychometric Validation of the BODY-Q in Danish Patients Undergoing Weight Loss and Body Contouring Surgery. AB - Background: A well-developed patient-reported outcome instrument is needed for use in Danish bariatric and body contouring patients. The BODY-Q is designed to measure changes in important patient outcomes over the entire patient journey, from obesity to post-body contouring surgery. The current study aims to psychometrically validate the BODY-Q for use in Danish patients. Methods: The process consisted of 3 stages: translation and linguistic validation, field-test, and data analysis. The translation was performed in accordance with the International Society for Pharmacoeconomics and Outcomes Research and World Health Organization guidelines, and field-test data were collected in 4 departments in 2 different hospitals. Field-test data were analyzed using Rasch Measurement Theory. Results: A total of 495 patients completed the Danish BODY-Q field-test 1-4 times, leading to a total of 681 assessments with an overall response rate at 76%. Cronbach alpha values were >= 0.90, and person separation index values were in general high. The Rasch Measurement Theory analysis provided broad support for the reliability and validity of the Danish version of the BODY Q scales. Item fit was outside the criteria for 34 of 138 items, and of these, 21 had a significant chi-square P value after Bonferroni adjustment. Most items (128 of 138) had ordered thresholds, indicating that response options worked as intended. Conclusion: The Danish version of the BODY-Q is a reliable and valid patient-reported outcome instrument for use in Danish bariatric and body contouring patients. PMID- 29184742 TI - A Breast Reconstruction Using a Breast Prosthesis and Capsular Flap for a Lymphocele Patient. AB - We encountered a very rare condition where the patient had a lymphocele under the skin envelope of the breast following mastectomy during the course of breast reconstruction with a tissue expander. The incidence rate of axillary lymphoceles is reported as 2.2-50% in breast cancer patients, but there have been no reports mentioning lymphoceles under the breast skin during the course of breast reconstruction with a prosthesis. The patient had a lymphocele in the lower lateral part of the breast following mastectomy and had multiple cellulitis-like inflammations. These inflammations were treated with conservative therapy such as administration of antibiotics, resting, and cooling. After 6 months of the initial surgery, the patient underwent complete resection of the lymphocele, preventative elimination of a possible lymphatic leakage, and breast reconstruction using a prosthesis combined with a capsular flap. The capsular flap is a transposition flap that uses capsular tissue around the expander to cover adjacent thinned skin. There were no postoperative complications such as breast skin necrosis, exposure of the prosthesis, or recurrence of the lymphocele and cellulitis. The patient had a successful breast reconstruction even though a lymphocele of the breast was observed. Even though a patient may have a lymphocele in the breast following mastectomy, with careful resection of the lymphocele, complete elimination of possible lymphatic leakage, and by performing the capsular flap technique, complete breast reconstruction with a breast prosthesis may be successful. PMID- 29184743 TI - Infectious Complications following Breast Reconstruction Using Tissue Expanders in Patients with Atopic Dermatitis. AB - Infectious complications represent one of the most prominent factors contributing to tissue expander (TE) loss in breast reconstruction procedures. Several patient characteristics that increase the risk for surgical-site infection or TE infection have been reported, but no study has focused on the relationship between atopic dermatitis (AD) and TE infection or surgical-site infection. Recently, we investigated 203 cases of breast reconstruction surgeries performed using TEs and noted that all 3 patients who had AD developed infectious complications that ultimately led to TE removal. Considering its pathophysiology, it is likely that patients with AD relatively easily develop infectious complications due to barrier dysfunction, abnormalities in innate immune responses, or colony formation by Staphylococcus aureus. Particular caution should be exercised for breast reconstruction using man-made materials in cases complicated by AD. PMID- 29184744 TI - Multidirectional Cranial Distraction Osteogenesis with Simplified Modifications for Treating Sagittal Synostosis. AB - Background: Multidirectional cranial distraction osteogenesis (MCDO) is a procedure of ours developed earlier for treating craniosynostosis. However, the numerous bone flaps led to prolonged operative time and occasional bone detachment from dura. We have since simplified the osteotomy design. In treating sagittal synostosis, required bone flaps have been reduced to 11 (from ~20). Methods: In a 2-year period (2014-2015), 5 boys with sagittal synostosis underwent MCDO using our simplified and fixed-form osteotomy. Mean age at surgery was 9.4 months (range, 8-11 months). Pre- and postoperative cranial morphology was assessed by cephalic index and by mid-sagittal vector analysis. Results: Improved cranial shape was confirmed by 3-dimensional CT scans and by mid sagittal vector index. Mean preoperative cephalic index (68.7) progressively increased to means of 78.5 immediately after distraction device removal, 75.2 at postoperative month 6, and 75.1 at 1 year postoperatively. There were no major complications, although transient cerebrospinal fluid leakage and loosening of anchor pins occurred in 1 patient. Conclusions: Simplified MCDO has a number of advantages over conventional distraction procedures such as discretionary reshaping/expansion of cranium and predictable osteogenesis and is a valid treatment option for patients with sagittal synostosis.

PMID- 29184747 TI - Intravenous Access in Infants Undergoing Bilateral Sural Nerve Grafts for Primary Brachial Plexus Exploration. AB - Background: Intravenous access (IVA) in infants undergoing primary brachial plexus exploration may be difficult. Both lower limbs are prepared and draped for sural nerve graft harvesting. The injured upper limb is also prepared and draped and is not available for IVA. In difficult IVA from the remaining upper limb, we have been using one of the feet for IVA. The infection rate and problems of intravenous infusions in this setting have never been studied in the literature. This study documents the infection rate and problems of intravenous infusions in these infants when a foot (within the sterile field) is used for IVA. Methods: This is a retrospective study of 63 consecutive infants undergoing primary brachial plexus exploration, and in whom IVA was obtained from one of the feet. Infection rate and problems of intravenous infusions were recorded. Results: No surgical wound infection and no infection of the IVA site were noted. There were no instances of accidental dislodgement of the intravenous cannula and no instances of extravasation. Conclusion: The use of one of the feet (within the sterile filed) for IVA is safe and acceptable in infants undergoing primary brachial plexus exploration and bilateral sural nerve grafting. PMID- 29184746 TI - Strategies for Reducing Fatal Complications in Liposuction. AB - Background: Liposuction has become one of the most common cosmetic surgical procedures, and severe complications secondary to this procedure have also increased significantly. That is why we carry out a research work to know the most frequent severe complications reported in the scientific literature to indicate criteria for prevention. Methods: English-language scientific publications about liposuction and its complications were analyzed using the PubMed.gov, from the beginning of PubMed's history through June 10, 2017. Five terms were used to define liposuction and its complications: "liposuction," "liposuction AND complications," liposuction AND major complications," "liposuction AND complications AND death," and "liposuction AND death." The quantities of results for the 5 phrases were analyzed, along with their contents. Results: One thousand sixty-three results were obtained from 1973 through June 10, 2017 for the phrase "Liposuction and Complications" in humans; for "Liposuction and Major Complications," 153 articles were found; for "Liposuction and Deaths," 89 articles were found; and 42 articles were obtained with the terms "Liposuction and Major Complications and Deaths." After final depuration, all those that were not specific to severe liposuction complications were eliminated, leaving a total of 39 articles that were included in our study. Five problems proved to be the most serious complications when performing liposuction: Thromboembolic disease, fat embolism, pulmonary edema, lidocaine intoxication, and intraabdominal visceral lesion. Conclusions: The 5 most important complications that can cause death in liposuction are easily preventable using simple measures and proper safety protocols that are described in this work. PMID- 29184748 TI - Filling the Spectrum Expander with Air-A New Alternative. AB - The Spectrum adjustable saline implant is optimal for prepectoral breast reconstruction as it can be placed virtually empty and thus flat, applying no pressure on the overlying skin flap. However, when saline is added, it tends to pool at the bottom of the implant resulting in its uneven surface and rippling. Air filling results in the uniform distribution within the implant shell and smooth even implant surface, which facilitates acellular dermal matrix adhesion. Pressure to the skin flap is averted, patients are more comfortable, and rippling is not seen. PMID- 29184749 TI - Pedicle-to-Perforator Bypass Using Supermicrosurgical Technique for Deep Inferior Epigastric Artery Perforator Flap Salvage. PMID- 29184750 TI - Long-Term Patency of Twisted Vascular Pedicles in Perforator-Based Propeller Flaps. AB - Background: Propeller flaps require torsion of the vascular pedicle of up to 180 degrees. Contrary to free flaps, where the relevance of an intact vascular pedicle has been documented, little is known regarding twisted pedicles of propeller flaps. As secondary surgeries requiring undermining of the flap are common in the extremities, knowledge regarding the necessity to protect the pedicle is relevant. The aim of this study was a long-term evaluation of the patency of vascular pedicle of propeller flaps. Methods: In a retrospective clinical study, 22 patients who underwent soft-tissue reconstruction with a propeller flap were evaluated after 43 months. A Doppler probe was used to locate and evaluate the patency of the vascular pedicle of the flap. Results: The flaps were used in the lower extremity in 19 cases, on the trunk in 3 cases. All flaps had healed. In all patients, an intact vascular pedicle could be found. Flap size, source vessel, or infection could therefore not be linked to an increased risk of pedicle loss. Conclusions: The vascular pedicle of propeller flaps remains patent in the long term. This allows reelevation and undermining of the flap. We therefore recommend protecting the pedicle in all secondary cases to prevent later flap loss. PMID- 29184751 TI - A New Modified Method of Correcting Cryptotia with a Subcutaneous Pedicled Flap. AB - We developed a surgical technique to correct cryptotia using a subcutaneous pedicled flap raised from the retroauricular region. A skin paddle over the caudal part of the auricular sulcus is designed and transferred to the skin defect of the upper posterior surface of the auricle. This procedure has been performed on 17 ears in 14 patients with cryptotia since 1992. There were no postoperative complications, such as necrosis of the flaps or deformities, and cryptotia did not recur in any patient. A satisfactory auricular contour with a sufficiently deep auriculotemporal sulcus was preserved in all cases. The intraoperative procedure to correct cryptotia and outcomes obtained are presented herein and compared with other procedures. PMID- 29184752 TI - Anatomical Analysis of Cutaneous Perforator Distribution in the Forearm. AB - Background: Few reports describe the distribution of cutaneous perforators from the radial and ulnar arteries in the forearm. This study aimed to map the location of the cutaneous perforators that arise directly from the radial and ulnar arteries in cadavers. Methods: Twenty-nine human cadaveric forearms were dissected. All radial and ulnar arteries cutaneous perforators were analyzed for total number and distribution. To define the distribution of each cutaneous perforator, the forearm was divided into 10 sections, with the sections labeled as 10%, 20%, 30%, and so on, beginning at the wrist. Results: From the radial artery, there were a total of 262 skin perforators with an average of 9.03 +/- 2.28 (mean +/- SD) per limb, whereas the total was 159 from the ulnar artery, with an average of 5.48 +/- 1.49 per limb. Additionally, 128 (49%) radial artery cutaneous perforators and 75 (47%) from the ulnar artery were concentrated in the 0-30% section of the forearm. Both the radial and ulnar arteries had many cutaneous perforators in the forearm section labeled 70%, with 32 of 262 (12%) cutaneous perforators of the radial artery and 27 of 159 (17%) cutaneous perforators of the ulnar artery located here. Conclusions: There were more cutaneous perforators from the radial artery than from the ulnar artery, and both were concentrated in the distal one-third of the forearm and in the forearm section labeled 70%. This information could be helpful when harvesting forearm flaps. PMID- 29184753 TI - Tissue Augmentation with Allograft Adipose Matrix For the Diabetic Foot in Remission. AB - Background: Repetitive stress on the neuropathic plantar foot is the primary cause of diabetic foot ulcers. After healing, recurrence is common. Modulating plantar pressure has been associated with extension of ulcer free days. Therefore, the goal of this study was to determine the effects of an injectable allograft adipose matrix in providing a protective padding and reducing the pressure in the plantar foot. Methods: After healing his recurrent ulcer using total contact casting, a 71-year-old man with a 9-year history of recurrent diabetic foot ulcers was treated with injection of allograft adipose matrix, procured from donated human tissue. This was delivered under postulcerative callus on the weight-bearing surface of the distal end of the first ray resection. As is standard in our clinic for tissue augmentation procedures, our patient underwent serial plantar pressure mapping using an in-shoe pressure monitoring system. Results: There was a 76.8% decrease in the mean peak pressure due to the fat matrix injected into the second metatarsal region and a 70.1% decrease in mean peak pressure for the first ray resection at the site of the postulcerative callus. By 2 months postoperatively, there was no evidence of residual callus. This extended out to the end of clinical follow-up at 4 months. Conclusion: The results from this preliminary experience suggest that allograft adipose matrix delivered to the high risk diabetic foot may have promise in reducing tissue stress over pre- and postulcerative lesions. This may ultimately assist the clinician in extending ulcer-free days for patients in diabetic foot remission.

PMID- 29184755 TI - Dissemination of high-level mupirocin-resistant CC22-MRSA-IV in Saxony. AB - Mupirocin is used for eradicating methicillin-resistant S. aureus (MRSA) in nasal colonization. A plasmid-borne gene, mupA, is associated with high-level mupirocin resistance. Despite the fact that, among all MRSA from a tertiary care center in the German state of Saxony, the prevalence of mupA, encoding high-level mupirocin resistance, was approximately 1% over a 15-year period from 2000-2015, a sharp increase to nearly 20% was observed in 2016/2017. DNA microarray profiling revealed that this was due to the dissemination of a variant of CC22-MRSA-IV ("Barnim Epidemic Strain" or "UK-EMRSA-15"), which, in addition to mecA, harbors mupA, aacA-aphD, qacA, and - in most isolates - erm(C). In order to prevent therapy failures and a further spread of this strain, the use of mupirocin should be more stringently controlled as well as guided by susceptibility testing. In addition, MRSA decolonization regimens that rely on other substances, such as betaisodona, polyhexanide or octenidine, should be considered. PMID- 29184757 TI - Biomechanical assessment of new surgical method instead of kyphoplasty to improve the mechanical behavior of the vertebra: Micro finite element study. AB - AIM: To reduce post treatments of kyphoplasty, as a common treatment for osteoporotic vertebrae. METHODS: This study suggests a new method for treating vertebrae by setting the hexagonal porous structure instead of the rigid bone cement mass in the kyphoplasty (KP). The KP procedure was performed on the fresh ovine vertebra of the level L1. Micro finite element modeling was performed based on micro computed tomography of ovine trabecular cube. The hexagonal porous structure was set on one cube instead of the bone cement mass. For the implant designing, two geometrical parameters were considered: Spacing diameter and thickness. RESULTS: The results of micro finite element analyses indicated the improvement in the mechanical behavior of the vertebra treated by the hexagonal porous structures, as compared to those treated by vertebroplasty (VP) and KP under static loading. The improvement in the mechanical behavior of the vertebra, was observed as 54% decrease in the amount of maximum Von Misses stress (improvement of stress distribution), in trabecular cube with embedded hexagonal structure, as compared to VP and KP. This is comparable to the results of the experimental study already performed; it was shown that the improvement of mechanical behavior of the vertebra was observed as: 83% increase in the range of displacements before getting to the ultimate strength (increasing the toughness) after setting hexagonal pearls inside vertebrae. Both the material and geometry of implant influenced the amount of Von Mises stress in the structure. CONCLUSION: The new proposed method can be offered as a substitute for the KP. The implant geometry had a more obvious effect on the amount of Von Mises stress, as compared to the implant material. PMID- 29184756 TI - Balance control during gait initiation: State-of-the-art and research perspectives. AB - It is well known that balance control is affected by aging, neurological and orthopedic conditions. Poor balance control during gait and postural maintenance are associated with disability, falls and increased mortality. Gait initiation - the transient period between the quiet standing posture and steady state walking is a functional task that is classically used in the literature to investigate how the central nervous system (CNS) controls balance during a whole-body movement involving change in the base of support dimensions and center of mass progression. Understanding how the CNS in able-bodied subjects exerts this control during such a challenging task is a pre-requisite to identifying motor disorders in populations with specific impairments of the postural system. It may also provide clinicians with objective measures to assess the efficiency of rehabilitation programs and better target interventions according to individual impairments. The present review thus proposes a state-of-the-art analysis on: (1) the balance control mechanisms in play during gait initiation in able bodied subjects and in the case of some frail populations; and (2) the biomechanical parameters used in the literature to quantify dynamic stability during gait initiation. Balance control mechanisms reviewed in this article included anticipatory postural adjustments, stance leg stiffness, foot placement, lateral ankle strategy, swing foot strike pattern and vertical center of mass braking. Based on this review, the following viewpoints were put forward: (1) dynamic stability during gait initiation may share a principle of homeostatic regulation similar to most physiological variables, where separate mechanisms need to be coordinated to ensure stabilization of vital variables, and consequently; and (2) rehabilitation interventions which focus on separate or isolated components of posture, balance, or gait may limit the effectiveness of current clinical practices. PMID- 29184758 TI - Atlantoaxial rotatory displacement in children. AB - AIM: To correlate the Pang and Lee class with the clinical course in a consecutive series of patients presenting with painful torticollis. METHODS: Forty-seven dynamic rotational computed tomography (CT) scans in 35 patients were classified into one of the five types defined by Pang and Li, including types I (atlantoaxial rotatopry fixation), II ("pathologic stickiness" without crossover of C1 on C2), III ("pathologic stickiness" with crossover of C1 on C2), IV (normal or muscular torticollis), and V (diagnostic grey zone). The Pang and Li class was then compared with the radiologist's report, which was graded abnormal, diagnosis of rotatory subluxation or fixation, or non-diagnostic. Medical records were reviewed and the clinical course was compared among the five sub-types. RESULTS: We reviewed 47 CT scans in 35 patients, and the majority were performed without sedation. The average age was 7.7 years (4-14 years old) and associated conditions included minor trauma (20%), surgical procedures around the head and neck (29%), and Grisels syndrome (20%). Twenty-six percent of our studies fell within the pathologic spectrum (5% type 1 or rotatory fixation, 21% types 2 and 3 or rotatory subluxation), while 45% were classified as muscular torticollis (45%) and 28% fell within the diagnostic grey zone. Seven radiologists interpreted these studies, and their interpretation was discordant in 45% of cases. Clinical resolution occurred in 27 of 29 cases for which follow-up was available. One of two patients with fixed rotatory subluxation required a C1-C2 arthrodesis. CONCLUSION: The Pang and Li classification characterizes a spectrum of abnormalities in rotation to facilitate communication, although the indications for dynamic CT scan should be further defined. PMID- 29184759 TI - Hypothenar fat pad flap vs conventional open release in primary carpal tunnel syndrome: A randomized controlled trial. AB - AIM: To compared outcomes between the hypothenar fat pad flap (HTFPF) and conventional open carpal tunnel release (COR) in primary carpal tunnel syndrome (CTS). METHODS: Forty-five patients (49 hands) were enrolled into the study from January 2014 to March 2016, 8 patients were excluded. Randomization was conducted in 37 patients (41 hands) by computer generated (Block of four randomization) into COR and HTFPF group. Nerve conduction study (NCS) included distal sensory latency (DSL), distal motor latency (DML), sensory amplitude (S-amp), motor amplitude (M-amp) and sensory nerve conduction velocity (SCV) were examined at 6 and 12 wk after CTR. Levine score, grip and pinch strength, pain [visual analog scale (VAS)], 2-point discrimination (2-PD), Semmes-Weinstein monofilament test (SWM), Phalen test and Tinel's sign were evaluated in order to compare treatment outcomes. RESULTS: The COR group, 19 patients (20 hands) mean age 50.4 years. The HTFPF group, 20 patients (21 hands) mean age 53.3 years. Finally 33 patients (36 hands) were analysed, 5 patients were loss follow-up, 17 hands in COR and 19 hands in HTFPF group. NCS revealed significant difference of DSL in HTFPF group at 6 wk (P < 0.05) compared with the COR group. S-amp was significant improved postoperatively in both groups (P < 0.05) but not significant difference between two groups. No significant difference of DML, M-amp and SCV postoperatively in both groups and between two groups. Levine score, pain (VAS), grip and pinch strength, 2-PD, SWM, Phalen test and Tinel's sign were improved postoperatively in both groups, but there was no significant difference between two groups. CONCLUSION: There is no advantage outcome in primary CTS for having additional HTFPF procedure in CTR. COR is still the standard treatment. Nevertheless, improvement of DSL and S-amp could be observed at 6 wk postoperatively. PMID- 29184760 TI - Rhabdomyolysis with different etiologies in childhood. AB - AIM: To investigate different etiologies and management of the rhabdomyolysis in children. METHODS: Eight pediatric rhabdomyolysis cases who applied to the Dokuz Eylul University Faculty of Medicine Department of Pediatric Nephrology with different etiologies between January 2004 and January 2012 were evaluated in terms of age, gender, admission symptoms, physical examination findings, factors provoking rhabdomyolysis, number of rhabdomyolysis attacks, laboratory results, family history and the final diagnosis received after the treatment. RESULTS: Average diagnosis ages of eight cases were 129 (24-192) +/- 75.5 mo and five of them were girls. All of them had applied with the complaint of muscle pain, calf pain, and dark color urination. Infection (pneumonia) and excessive physical activity were the most important provocative factors and excessive licorice consumption was observed in one case. In 5 cases, acute kidney injury was determined and two cases needed hemodialysis. As a result of the further examinations; the cases had received diagnoses of rhabdomyolysis associated with mycoplasma pneumoniae, sepsis associated rhabdomyolysis, licorice-induced hypokalemic rhabdomyolysis, carnitine palmitoyltransferase II deficiency, very long-chain acyl-CoA dehydrogenase deficiency, congenital muscular dystrophy and idiopathic paroxysmal rhabdomyolysis (Meyer-Betz syndrome). CONCLUSION: It is important to distinguish the sporadic and recurrent rhabdomyolysis cases from each other. Recurrent rhabdomyolysis cases should follow up more regardful and attentive. PMID- 29184761 TI - Estimating extraction fraction and blood flow by combining first-pass myocardial perfusion and T1 mapping results. AB - Background: Quantifying myocardial perfusion is complicated by the complexity of pharmacokinetic model being used and the reliability of perfusion parameter estimates. More complex modeling provides more information about the underlying physiology, but too many parameters in complex models introduce a new problem of reliable estimation. To overcome the problem of multiple parameters, we have developed a technique that combines knowledge from two different cardiac magnetic resonance (MR) imaging techniques: dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and T1 mapping. Using extracellular volume (ECV) estimates from T1 mapping may allow more robust model parameter estimates. Methods: Simulations and human scans were performed. The myocardial perfusion scans used an ungated saturation recovery prepared TurboFLASH pulse sequence. Four short-axis (SA) slices were acquired after a single saturation pulse with a saturation recovery time of ~25 ms before the first slice. Gadoteridol was injected and ~240 frames were acquired over a minute with shallow breathing and no electrocardiograph (ECG) gating. This was followed 20+/-5 minutes later by an injection of regadenoson to induce hyperemia. The data were acquired using an under-sampled golden angle radial acquisition. Modified look-locker inversion recovery (MOLLI) T1 mapping was performed in 3 slices pre- and post-contrast. The pre- and post contrast T1 maps were used for ECV estimation. Quantification of perfusion was done using a 4-parameter model with additional information about ECV supplied during model fitting. Phase contrast scans of the coronary sinus (CS) were acquired at rest and immediately after the stress perfusion acquisition to estimate global flow. Results: Without ECV information, the 5-parameter model fails to converge to a unique solution and often gives incorrect estimates for the perfusion parameters. The myocardial blood flow (MBF) estimates during rest and stress were 0.9+/-0.1 and 2.3+/-0.6 mL/min/g, respectively. The extraction fraction estimates were 0.49+/-0.04 and 0.34+/-0.05 during rest and stress, respectively. Conclusions: These results show that it is possible to successfully fit a dynamic perfusion model with an extraction fraction parameter by using information from T1 mapping scans. This hybrid approach is especially important when the 5-parameter model alone fails to converge on a unique solution. This work is a good example of exploiting information overlaps between various cardiac MR imaging techniques.

Conclusions: The analysis is easy-to-use and accessible for routine implementation of DCE-MRI into clinical practice. PMID- 29184763 TI - Usefulness of enhancement-perfusion mismatch in differentiation of CNS lymphomas from other enhancing malignant tumors of the brain. AB - Background: Surgical planning and treatment options for primary or secondary central nervous system lymphomas (PCNSL or SCNSL) are different from other enhancing malignant lesions such as glioblastoma multiforme (GBM), anaplastic gliomas and metastases; so, it is critical to distinguish them preoperatively. We hypothesized that enhancement-perfusion (E-P) mismatch on dynamic susceptibility weighted magnetic resonance (DSC-MR) perfusion imaging which corresponds to low mean relative cerebral blood volume (mean rCBV) in an enhancing portion of the tumor should allow differentiation of CNS lymphomas from other enhancing malignant lesions. Methods: We retrospectively reviewed pre-treatment MRI exams, including DSC-MR perfusion images of 15 lymphoma patients. As a control group, pre-treatment DSC-MR perfusion images of biopsy proven 18 GBMs (group II), 13 metastases (group III), and 10 anaplastic enhancing gliomas (group IV) patients were also reviewed. Region of interests (ROIs) were placed around the most enhancing part of tumor on contrast-enhanced T1WI axial images and images were transferred onto co-registered DSC perfusion maps to obtain CBV in all 4 groups. The mean and maximum relative CBV values were obtained. Statistical analysis was performed on SPSS software and significance of the results between the groups was done with Mann-Whitney test, whereas optimal thresholds for tumor differentiation were done by receiver operating characteristic (ROC) analysis. Results: The enhancing component of CNS lymphomas were found to have significantly lower mean rCBV compared to enhancing component of GBM (1.2 versus 4.3; P<0.001), metastasis (1.2 versus 2.7; P<0.001), and anaplastic enhancing gliomas (1.2 versus 2.4; P<0.001). Maximum rCBV of enhancing component of lymphoma were significantly lower than GBM (3.1 versus 6.5; P<0.001) and metastasis (3.1 versus 4.9; P<0.013), and not significantly lower than anaplastic enhancing gliomas (3.9 versus 4.2; P<0.08). On the basis of ROC analysis, mean rCBV provided the best threshold [area under the curve (AUC) =0.92] and had better accuracy in differentiating malignant lesions. Conclusions: E-P mismatch in DSC perfusion MR, i.e., low mean rCBV in an enhancing portion of the tumor is strongly suggestive of lymphoma and should allow differentiation of CNS lymphoma from other enhancing malignant lesions. PMID- 29184764 TI - Dual energy CT angiography in peripheral arterial stents: optimal scanning protocols with regard to image quality and radiation dose. AB - Background: To determine the optimal scanning protocols of dual energy computed tomography angiography (DECTA) in terms of radiation dose and image quality assessment at different keV levels, and compare it with conventional computed tomography angiography (CTA) in patients treated with peripheral arterial stents. Methods: Twenty-nine patients with previous stent placement in peripheral arteries were evaluated with DECTA. Images were reconstructed with virtual monochromatic spectral imaging (VMS) at 65, 68, 70 and 72 keV and adaptive statistical iterative reconstruction (ASIR) at 50% compared with CTA. Image quality comprising image noise, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were assessed, and radiation dose was compared. Effects of different type of peripheral arterial stents on image quality were also evaluated. Fifty six uniquely identified stents that were located in common iliac arteries (CIA), external iliac arteries (EIA) and superficial femoral arteries (SFA) were evaluated. Results: Within subjects, the results showed that DECTA images (VMS) had less noise than the CTA images for CIA, EIA and SFA stents, with the lowest noise at 72 keV. Also, the VMS images had greater SNR than the CTA images for the EIA stents (P<0.05); and the VMS images had greater CNR than the CTA images for CIA, EIA, and SFA stents (P<0.001). Also, on CT attenuation, VMS continued to outperform CTA, but to a lesser extent. Between subjects, average VMS noise varied significantly with the type of the stent used (P=0.025) for CIA stents. Radiation dose was highly significant between DECTA and conventional CTA scans (6.98 vs. 7.40 mSv, P=0.047). Conclusions: We conclude that an optimal scanning protocol consisting of 72 keV and 50% ASIR leads to better image quality for DECTA in peripheral arterial stenting when compared to conventional CTA. PMID- 29184765 TI - The novel targets of DL-3-n-butylphthalide predicted by similarity ensemble approach in combination with molecular docking study. AB - Background: DL-3-n-butylphthalide (NBP) is a drug for treating acute ischemic stroke, and may play a neuroprotective role by acting on multiple active targets. The aim of this study was to predict the target proteins of NBP in mammalian cells. Methods: The similarity ensemble approach search tool (SEArch), one of the commonly used public bioinformatics tools for target prediction, was employed in the experiment. The molecular docking of NBP to target proteins was performed by using the three-dimensional (3-D) crystal structure, substrate free. The software AutoDock Vina was used for all dockings. The binding targets of NBP were illustrated as 3-D and 2-D diagrams. Results: Firstly, the results showed that NBP bounded to the same binding site on NAD(P)H quinone oxidoreductases (NQO1) as the substrate FAD, leading to competitive inhibition for the catalytic site with 7.2 kcal/mol. This might break the 3-D structure of NQO1 and bring about P53 degradation, resulting in a decrease of p53-mediated apoptosis in ischemic brain cells. Secondly, NBP might exert its therapeutic effect on acute ischemic stroke via modulating indoleamine 2,3-dioxygenase (IDO) bioactivity after associating with it. NBP could alleviate the depression following ischemic stroke by inhibiting IDO. Thirdly, NBP might modulate the function of NADH-ubiquinone oxidoreductase by competitively embedding itself into this complex, further affecting mitochondrial respiration in cerebrovascular diseases as an anti oxidant agent. Conclusions: Three potential target proteins of NBP were identified, which may provide a novel aspect for better understanding the protective effects of NBP on the nervous system at the molecular level. PMID- 29184767 TI - Preliminary results of vibro-acoustography evaluation of bone surface and bone fracture. AB - Background: Vibro-acoustography (VA) uses two co-focused ultrasound beams with slightly different frequencies. The beams interact and generate a low-frequency focus to excite an object. Methods: A two-element confocal ultrasound transducer with central frequency at 3.2 MHz was used to generate the low-frequency excitation (30 kHz) and the response of the bone to that excitation was acquired by a dedicated hydrophone. The face of the confocal transducer was positioned parallel to the surface of the bone at a focal length of 7 cm. The hydrophone was fixed to the side of the transducer, out of the path of the ultrasonic beam. Results: The resulting image clearly showed the bone fracture with resolution of 0.25 mm and high contrast with well-defined borders. Conclusions: In this paper, we present preliminary results of VA imaging of bone surface and of bone fracture using an experimental set-up. Our results encourage future studies using VA to evaluate bone fractures. PMID- 29184766 TI - An investigation of correlation between left coronary bifurcation angle and hemodynamic changes in coronary stenosis by coronary computed tomography angiography-derived computational fluid dynamics. AB - Background: To investigate the correlation between left coronary bifurcation angle and coronary stenosis as assessed by coronary computed tomography angiography (CCTA)-generated computational fluid dynamics (CFD) analysis when compared to the CCTA analysis of coronary lumen stenosis and plaque lesion length with invasive coronary angiography (ICA) as the reference method. Methods: Thirty patients (22 males, mean age: 59+/-6.9 years) with calcified plaques at the left coronary artery were included in the study with all patients undergoing CCTA and ICA examinations. CFD simulation was performed to analyze hemodynamic changes to the left coronary artery models in terms of wall shear stress, wall pressure and flow velocity, with findings correlated to the coronary stenosis and degree of bifurcation angle. Calcified plaque length was measured in the left coronary artery with diagnostic value compared to that from coronary lumen and bifurcation angle assessments. Results: Of 26 significant stenosis at left anterior descending (LAD) and 13 at left circumflex (LCx) on CCTA, only 14 and 5 of them were confirmed to be >50% stenosis at LAD and LCx respectively on ICA, resulting in sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 100%, 52%, 49% and 100%. The mean plaque length was measured 5.3+/-3.6 and 4.4+/-1.9 mm at LAD and LCx, respectively, with diagnostic sensitivity, specificity, PPV and NPV being 92.8%, 46.7%, 61.9% and 87.5% for extensively calcified plaques. The mean bifurcation angle was measured 83.9+/ 13.6o and 83.8+/-13.3o on CCTA and ICA, respectively, with no significant difference (P=0.98). The corresponding sensitivity, specificity, PPV and NPV were 100%, 78.6%, 84.2% and 100% based on bifurcation angle measurement on CCTA, 100%, 73.3%, 78.9% and 100% based on bifurcation angle measurements on ICA, respectively. Wall shear stress was noted to increase in the LAD and LCx models with significant stenosis and wider angulation (>80o), but demonstrated little or no change in most of the coronary models with no significant stenosis and narrower angulation (<80o). Conclusions: This study further clarifies the relationship between left coronary bifurcation angle and significant stenosis, with angulation measurement serving as a more accurate approach than coronary lumen assessment or plaque lesion length for determining significant coronary stenosis. Left coronary bifurcation angle is suggested to be incorporated into coronary artery disease (CAD) assessment when diagnosing significant CAD. PMID- 29184768 TI - Identifying osteoporotic vertebral endplate and cortex fractures. AB - Osteoporosis is the most common metabolic bone disease, and vertebral fractures (VFs) are the most common osteoporotic fracture. A single atraumatic VF may lead to the diagnosis of osteoporosis. Prevalent VFs increase the risk of future vertebral and non-vertebral osteoporotic fracture independent of bone mineral density (BMD). The accurate and clear reporting of VF is essential to ensure patients with osteoporosis receive appropriate treatment. Radiologist has a vital role in the diagnosis of this disease. Several morphometrical and radiological methods for detecting osteoporotic VF have been proposed, but there is no consensus regarding the definition of osteoporotic VF. A vertebra may fracture yet not ever result in measurable changes in radiographic height or area. To overcome these difficulties, algorithm-based qualitative approach (ABQ) was developed with a focus on the identification of change in the vertebral endplate. Evidence of endplate fracture (rather than variation in vertebral shape) is the primary indicator of osteoporotic fracture according to ABQ criteria. Other changes that may mimic osteoporotic fractures should be systemically excluded. It is also possible that vertebral cortex fracture may not initially occur in endplate. Particularly, vertebral cortex fracture can occur in anterior vertebral cortex without gross vertebral deformity (VD), or fractures deform the anterior vertebral cortex without endplate disruption. This article aims to serve as a teaching material for physicians or researchers to identify vertebral endplate/cortex fracture (ECF). Emphasis is particularly dedicated to identifying ECF which may not be associated apparent vertebral body collapse. We believe a combined approach based on standardized radiologic evaluation by experts and morphometry measurement is the most appropriate approach to detect and classify VFs. PMID- 29184769 TI - Diffuse glioblastoma resembling acute hemorrhagic leukoencephalitis. AB - We report the case of a young man with sudden onset of diplopia after an upper respiratory tract infection. Based on the first radiological findings acute hemorrhagic leukoencephalitis, a variant of acute disseminated encephalomyelitis, was suspected and treatment with high dose intravenous dexamethasone was started but it was stopped for intolerance. The patient clinically worsened, developing gait instability, ataxia and ophthalmoplegia; brain MRI performed 20 days later showed severe progression of the disease with subependymal dissemination. After brain biopsy of the right temporal lesion the histological diagnosis was glioblastoma. These findings suggest that MRI features of acute hemorrhagic leukoencephalitis may dissimulate the diagnosis of diffuse glioma/glioblastoma. This case underscores the importance of considering diffuse glioma in the differential diagnosis of atypical signs and symptoms of acute hemorrhagic leukoencephalitis and underlines the relevant role of integrating neuroradiologic findings with neuropathology. PMID- 29184770 TI - Dentinogenic ghost cell tumor-a rare case report with review of literature. AB - Dentinogenic ghost cell tumors (DGCT) are very rare tumors considered as solid variants of calcifying epithelial odontogenic cysts (CEOC). They are locally invasive neoplasms and their main characteristic features are ameloblastoma like odontogenic epithelial proliferation, an aberrant keratinization in the form of ghost cells and dysplastic dentin. DGCT occur as two forms intraosseous (central) and extra osseous (peripheral), of which more aggressive intraosseous variety requires careful monitoring and aggressive local resection to prevent recurrence. This paper discusses a case of a 14-year-old male patient with a complaint of swelling in his right mandibular premolar molar region since 4 months and missing permanent right mandibular canine and first premolar was also observed. The lesion was diagnosed with radiological, cytological and histopathological investigations which revealed it to be rarest entity.

PMID- 29184774 TI - Updates on the epidemiology and risk factors for penile cancer. AB - Penile cancer is a rare neoplasm representing less than 1% of all malignancies in the USA and Europe but is a significant public health hazard in the developing world. Male neonatal circumcision has been associated with a dramatic decrease in penile cancer rates with countries such as Israel, where circumcision is widely performed, having the lowest incidence in the world at <0.1% of malignancies. Many risk factors have been identified for penile cancer including phimosis, lack of circumcision, obesity, lichen sclerosis, chronic inflammation, smoking, UVA phototherapy, socioeconomic status, human papillomavirus (HPV) infection and immune compromised states. The relationship between these factors and invasive disease varies and continues to be investigated. Our objective was to present a contemporary overview of the epidemiology and risk factors for invasive penile cancer. PMID- 29184776 TI - Topical Therapy for non-invasive penile cancer (Tis)-updated results and toxicity. AB - Penile cancer is a rare malignancy estimated to affect 26,000 men globally each year. The association with penile cancer, in particular non-invasive disease, and human papilloma virus (HPV) is well known. Ninety-five percent of cases of penile cancer are squamous cell carcinoma (SCC), which are staged using the TNM staging system. Terminology describing the histological appearance of non-invasive penile cancer has changed with all cases grouped under the umbrella term of penile intraepithelial neoplasia (PeIN); either undifferentiated or differentiated. This replaces previous terms such as carcinoma in situ (CIS) and eponymous names such as Bowen's disease. This change is recognised by the World Health Organisation (WHO). The topical treatments most commonly used for PeIN are 5-fluorouracil (5 FU) and imiquimod (IQ). Other treatments such as photodynamic therapy (PDT) are used but to a lesser degree. The evidence for all of these treatments is heterogenous with no randomised data available. Overall up to 57% complete response has been reported with a low number of serious adverse events. In this article, we aim to review the available evidence for the topical treatment of non invasive penile cancer specifically regarding its efficacy and toxicity. PMID- 29184775 TI - Relationship between human papillomavirus and penile cancer-implications for prevention and treatment. AB - Penile cancer is a rare disease in the United States, but rates are increasing, causing concern. Several risk factors have been associated with the disease, including human papillomavirus (HPV) infection. Knowledge of HPV pathogenesis has led to the development of a vaccine, which has proven instrumental in reducing the incidence of female HPV-related cancers, but results in men have yet to be elucidated. Fortunately, rates of vaccination are up-trending in both males and females in the past several years. In addition, targeted therapies are the focus of several ongoing research efforts. Some of these therapeutics are currently in use, while several are in trials. With continued patient education and research, both treatment and prevention of HPV-related pre-malignant lesions and penile cancer will likely diminish. PMID- 29184778 TI - Technical considerations to minimize complications of inguinal lymph node dissection. AB - Penile cancer is a rare malignancy with a high propensity for regional dissemination. Current guidelines recommend inguinal lymphadenectomy in patients with penile cancer for palpable inguinal lymph nodes or in certain cases of nonpalpable inguinal lymph nodes. For many years, this procedure was performed with a traditional open approach and carried significant morbidity due to severe lymphedema, flap necrosis, wound infections, and seroma formation. The evolution of inguinal lymphadenectomy surgery for patients with penile cancer to a more minimally invasive approach has greatly reduced the morbidity of the procedure. Complications of inguinal lymphadenectomy can be minimized with modifications in surgical approach with the use of endoscopic, robotic, and various reconstructive methods. This review focuses on various intraoperative techniques to reduce morbidity in inguinal lymphadenectomies for penile cancer. PMID- 29184777 TI - Penile sparing surgical approaches for primary penile tumors: preserving function and appearance. AB - Penile cancer is a rare and potentially disfiguring disease. There are multiple treatment options for primary penile lesions. Penile sparing approaches offer an attractive option as they can provide several quality of life benefits without detrimental oncologic outcomes. With appropriate diagnostic evaluation and staging, penile sparing techniques provide proper cancer control with improved cosmetic and functional results. Regardless of the chosen treatment modality, a commitment to close follow-up remains a critical component of all treatment considerations. The goal of this review is to provide an overview of the multiple treatment strategies for primary penile tumors with a focus on penile sparing surgical approaches. PMID- 29184779 TI - Robotic inguinal lymphadenectomy for penile cancer: the why, how, and what. AB - Squamous cell carcinoma of the penis (SCC-P) demonstrates a reliable pattern of spread to the lymph nodes of the groin. High grade and higher stage (pT1b or greater) SCC-P demonstrate a higher propensity for metastasis to the inguinal lymph nodes. Further, lymphadenopathy progresses in a predictable fashion, from superficial inguinal lymph nodes to deep inguinal lymph nodes to pelvic lymph nodes, with limited survival noted for those patients with progression to pelvic lymph nodes. Fortunately, inguinal lymphadenectomy can provide cure and improvement in RFS for SCC-P. Unfortunately open inguinal lymphadenectomy is associated with significant morbidity. Perhaps owing to this morbidity, inguinal lymphadenectomy is underperformed in the US. In other words, urologists only offer inguinal lymphadenectomy for high risk SCC-P in only a minority of cases and even when performed, lymph node yield is often unsatisfactory (less than 8 nodes per groin). Recently, a laparoendoscopic inguinal lymphadenectomy has been developed as a new approach to offer potentially curative lymph node resection while minimizing morbidity. The robotic platform has since been adapted for this approach and several reports demonstrate significant improvements in morbidity while maintaining oncologic equivalency. This review highlights the rationale for inguinal lymphadenectomy, inguinal lymph node anatomy, and technical considerations and outcomes of laparoscopic and robotic inguinal lymphadenectomy. PMID- 29184780 TI - The role of PET/CT imaging in penile cancer. AB - Positron emission tomography (PET) imaging with 18F-fluorodeoxyglucose (FDG) combined with computed tomography (CT) provides functional imaging combined with anatomic information, improving diagnostic accuracy and confidence. Although virtually all primary penile tumors are FDG-avid, PET/CT is not recommended for primary tumor staging as it has limited spatial resolution and is hampered by urinary FDG excretion. The accuracy of PET/CT for lymph node staging seems to improve with the pretest likelihood of metastatic nodes. In groins with normal physical examination, sensitivity is only 57%. In groins with palpably enlarged lymph nodes, sensitivity of PET/CT reaches 96%. For pelvic lymph nodes and distant metastases, PET/CT is more accurate if inguinal metastases are present. However, these results are based on a very limited number of studies. Overall, the role of PET/CT imaging in penile cancer remains ambiguous, especially in inguinal lymph nodes. During staging and follow-up, it may be particularly useful in detecting pelvic lymph node metastases and occult distant metastases prior to systemic chemotherapy and/or extensive surgery, improving selection of patients that are most likely to benefit from such therapies. PMID- 29184781 TI - Clinical scenarios for neoadjuvant chemotherapy of squamous penile cancer that is clinically node positive. AB - Squamous penile cancer may be localized to the phallus, metastatic to regional lymph nodes, or metastatic to distant lymph nodes or other organs. In the clinical situation of regional lymph node metastasis, a multimodality approach can have a big impact on outcomes. In particular, use of systemic chemotherapy as a neoadjuvant treatment is discussed, with several examples illustrating instances of regression and of resistance, and contrasting with adjuvant timing for use of chemotherapy. Radiation with coordinated combined chemotherapy is another complementary, locally directed approach that can be considered for men with squamous penile cancer with regional lymph node spread. The randomized trial InPACT (International Penile Cancer Adjuvant Chemotherapy Trial, NCT02305654) will enroll some of the squamous penile cancer patients with clinically node positive disease. PMID- 29184782 TI - Beyond chemotherapy for advanced disease-the role of EGFR and PD-1 inhibitors. AB - Penile squamous cell carcinoma (SCC) is a rare malignancy with limited treatment options when the tumor is unresectable and/or chemorefractory. Triplet systemic chemotherapy regimens including taxane and cisplatin are recommended, but the response duration can be short and the treatment-related toxicity high. Only a small proportion of patients survive 1 year or longer with the current standard treatment paradigm. Beyond chemotherapy, the use of novel targeted agents, either alone or in combination with traditional chemotherapeutic agents, has appeared to have promising efficacy in patients with platinum-refractory penile cancer. The frequent overexpression of PD-L1 in advanced penile SCC indicates the potential efficacy of PD-1 inhibitors. Upcoming clinical trials using the immune check point inhibitors may provide exciting landscape and change the paradigm for patients in the future. PMID- 29184783 TI - Contemporary role of radiotherapy in the management of penile cancer. AB - Penile cancer is a rare clinical entity that contributes to significant patient morbidity and mortality. Human papilloma virus (HPV) plays an important role in the carcinogenesis of penile squamous cell carcinoma (SCC), is associated with improved clinical outcomes, and is predictive for response to treatment with chemotherapy and radiotherapy. Historically, treatment consisted of radical surgery with partial or total penectomy. While effective for local control, surgical resection can impart significant physical, psychological and sexual dysfunction for afflicted men. Organ preservation strategies offer significant quality of life advantages over standard surgery and can be utilized without compromising oncological control. As an alternative or adjunct to surgical resection, radiation therapy can be used for organ preservation strategies successfully in up to 70% of patients. A variety of treatment techniques can be employed depending on the location and burden of disease. Limited disease can be amenable to treatment with interstitial brachytherapy, surface mold plesiotherapy or external beam radiotherapy. For locally advanced presentations, or for patients not amenable to surgical resection, excellent clinical outcomes can be achieved using a combination of chemotherapy and radiation therapy. Here, we discuss the management of penile SCC using modern radiation therapy treatment techniques, the expected clinical outcomes for organ preservation, as well as the management of side-effects and toxicities. While large randomized trials are being developed, the management of penile cancer is informed from the management of other of other anogenital malignancies, which we also review. PMID- 29184784 TI - Surveillance strategies in the management of penile cancer. AB - Penile cancer is a rare disease and can be associated with a high risk of recurrence in regional lymph nodes and distant sites. Surveillance strategies geared towards early detection and treatment are recommended given the significant morbidity and mortality associated with recurrences. Although physical examination is the single most important surveillance strategy, imaging is an important adjunct in high-risk disease and certain clinical scenarios. PMID- 29184785 TI - Psychosocial impact of penile carcinoma. AB - Penile carcinoma is a rare malignancy with a potential for local invasion and regional/distant extension. Penile cancer can be cured in over 80% of cases if diagnosed early. However, local treatment, although potentially lifesaving, can be mutilating and devastating for the patient's psychological well-being. In patients with long-term survival after penile cancer, sexual dysfunction, voiding problems and cosmetic penile appearance may adversely affect the patient's quality of life. Although there is little data in the literature about psychosocial impact of penile carcinoma, organ-preserving treatment seems to allow for better quality of life and sexual function and should be offered to all patients whenever feasible. PMID- 29184786 TI - Phosphodiesterase type 5 inhibitors usage and prostate cancer: a match-paired analysis. AB - Background: To treat erectile dysfunction (ED), phosphodiesterase type 5 inhibitors (PDE5i) are commonly used. However, to date, only a few studies exist evaluate a possible effect on the incidence of prostate cancer. One such study completed by the authors' institution suggested men who use PDE5i for ED may have a lower incidence of prostate cancer. This study was meant to address some of the shortcomings of the former study and further characterize the link between prostate cancer and PDE5i use. Methods: A retrospective, match-paired analysis was undertaken: 5,717 patients were identified between 2000 and 2011; a 1:2 match pair analysis ultimately identified 394 cases with cancer and 788 controls without cancer. Pairs were matched based on age, ethnicity, and PSA value. Results: No correlation existed between PDE5i use and prostate cancer [OR 1.02, 95% confidence interval (CI): 0.78-1.35, P=0.8842] or diabetes mellitus and prostate cancer (OR 1.12, 95% CI: 0.84-1.48, P=0.4499). A statistically significant correlation was demonstrated with PSA and prostate cancer (OR 1.48, 95% CI: 1.38-1.58, P<0.0001). Conclusions: The data suggest that there is essentially no association with PDE5i use and prostate cancer. PMID- 29184787 TI - Correlation of self-reported urologic symptoms with systemic health conditions in minority men. AB - Background: To investigate the correlation between presence and severity of urologic symptoms and self-reported systemic health conditions in minority men. Methods: Questionnaires were distributed at a Men's Minority Health Fair. Urologic symptoms were assessed with the International Prostate Symptom Score (IPSS), Sexual Health Inventory for Men (SHIM) and NIH Chronic Prostatitis Symptom Score (CPSI). Each was graded as absent/mild [0], moderate [1] or severe [2] by standard criteria for each and totaled for a urologic score (US). Other questions included age, height/weight and queried heart disease, diabetes, anxiety/stress, sleep apnea and neurologic disease. A systemic score (SS) graded each plus obesity for 6 domains (0-2 for each). Results: A total of 52 men completed the surveys with a mean age of 58.8 (range, 37-76) years. By symptom score criteria, 17 (33%) had 1 urologic condition, 19 (37%) had 2 and 5 (10%) had all 3. Mean total US was 1.9 (range, 0-6) and mean SS was 2.9 (range, 0-10). There was a strong correlation between US and SS (Spearman Rho =0.73, P<0.0001). The hierarchy of systemic condition impact on US was cardiovascular > anxiety > obesity > diabetes > sleep apnea > neurologic. By multivariable analysis, after adjusting for age, each systemic component strongly correlated with the US. The multivariable model with age plus all of the systemic scores predicted US more accurately than with any one of its components alone. Conclusions: Self-reported systemic health conditions correlate strongly with presence and severity of urologic symptoms in minority men. PMID- 29184788 TI - Racial variations in response to intralesional collagenase clostridium histolyticum in men with Peyronie's disease. AB - Background: An examination of potential racial variations between Caucasian American (CA) and African American (AA) men in the efficacy and safety of collagenase clostridium histolyticum (CCH) in the treatment of Peyronie's disease (PD). Methods: We retrospectively reviewed the records for all patients treated with CCH for PD between 04/2014 and 05/2017. Patients were divided into two groups based on their self-reported race. The primary outcomes of interest were final change in curvature after CCH treatment regardless of number of CCH cycles received, and frequency of treatment-related adverse events (TRAEs). Results: A total of 159 patients were included in the study, of which 146 (91.8%) were CA while 13 (8.2%) were AA. Mean duration of PD was 28.3 months for CA patients and 16.8 months for CA patients (P=0.436). There was no significant difference in final change in curvature CA and AA patients (15.9 degrees vs. 13.1 degrees respectively, P=0.445). There was no statistically significant difference in frequency of TRAEs between CA patients (17, 12%) and AA patients (0, 0%) (P=0.208). Conclusions: Although racial variations in efficacy and safety of CCH in patients with PD have not been addressed in the literature, preliminary results from our study suggest that CCH therapy may be equally efficacious and safe in both CA and AA men. There was no statistically significant difference in final change in curvature, International Index of Erectile Function (IIEF) scores, penile length, or TRAEs after CCH treatment between CA and AA patients. PMID- 29184789 TI - Effect of collagenase Clostridium histolyticum on penile vascular and morphological parameters in patients with Peyronie's disease. AB - Background: To examine the changes in penile vascular parameters after the administration of collagenase Clostridium histolyticum (CCH) in patients with Peyronie's disease (PD). Methods: We retrospectively reviewed the records for all patients treated with CCH for PD between 04/2014 and 05/2017 who underwent penile duplex Doppler ultrasound (PDDU) after pharmacologically induced erection both before and after four cycles of CCH treatment. The primary outcomes measured were changes in peak systolic velocity (PSV), end diastolic velocity (EDV), and resistive index (RI) after CCH treatment. Paired t-tests, chi-squared tests, and correlation coefficients were performed between functional and vascular parameters before and after four rounds of CCH to determine statistical significance (P<0.05). Results: A total of 51 patients were included in the study. After four cycles of CCH therapy, there was no statistically significant change in PSV, EDV, RI, or International Index of Erectile Function score when compared to baseline. Similarly, there was no correlation between vascular parameters and change in curvature. There was a statistically significant change in penile curvature (60+/-16.9 to 40.8+/-14.9, P<0.001) and erect penile circumference (11.6+/-1.0 to 11.9+/-1.0 cm, P<0.05) after treatment. Conclusions: In spite of a significant change in penile curvature, this change did not correlate with changing penile vascular or morphological parameters. Overall, CCH therapy seems to have a negligible impact on penile vasculature, furthering evidence of its favorable safety profile. PMID- 29184790 TI - Factors associated with acutely elevated serum creatinine following radical tumour nephrectomy: the Correlates of Kidney Dysfunction-Tumour Nephrectomy Database study. AB - Background: To identify factors associated with acutely elevated serum creatinine (SCr) within 7 days of radical tumour nephrectomy. Methods: The study population consisted of 130 consecutive patients managed for renal tumours. The primary outcome was acute kidney injury (AKI) (defined as SCr increase >=50% above baseline), assessed using multivariable logistic regression analysis. The secondary outcome was SCr percentage increase, assessed using multivariable linear regression analysis. Results: Following nephrectomy, the mean percentage increase in SCr in the first week was 55%+/-29%, and 77 (59%) patients experienced AKI. Independent predictors of AKI post-nephrectomy were male gender [adjusted odds ratio (OR): 2.67; 95% confidence interval (95% CI): 1.01, 6.93], urine albumin-creatinine ratio (OR: 0.66; 95% CI: 0.47, 0.91), preoperative estimated glomerular filtration rate (eGFR) (OR: 1.03; 95% CI: 1.00, 1.05), laparoscopic nephrectomy (OR: 3.02; 95% CI: 1.00, 9.12), and non-clear cell renal cell carcinoma (RCC) (OR: 2.93; 95% CI: 1.04, 8.29). Independent predictors of a SCr increase were male gender (beta: 12.0; 95% CI: 2.69, 21.3), urine albumin creatinine ratio (beta: -3.36; 95% CI: -6.55, -0.16), preoperative eGFR (beta: 0.38; 95% CI: 0.10, 0.66), laparoscopic nephrectomy (beta: 12.7; 95% CI: 1.05, 24.3) and obesity (beta: 9.94, 95% CI: 0.61, 19.3). Conclusions: Male gender, albuminuria, eGFR and laparoscopic nephrectomy independently associated with acutely elevated serum creatinine following radical tumour nephrectomy. PMID- 29184791 TI - Comprehensive pelvic floor physical therapy program for men with idiopathic chronic pelvic pain syndrome: a prospective study. AB - Background: Male chronic pelvic pain syndrome (CPPS) is a heterogeneous constellation of symptoms that causes significant impairment and is often challenging to treat. In this prospective study, we evaluated men with CPPS who underwent comprehensive pelvic floor physical therapy (PFPT) program. We used the previously validated Genitourinary Pain Index (GUPI) to measure outcomes. Methods: We included 14 men who underwent physical therapy for idiopathic CPPS from October 2015 to October 2016. Men with clearly identifiable causes of pelvic pain, such as previous surgery, chronic infection, trauma, prostatitis and epididymitis were excluded. Treatment included: (I) manual therapy (internal and external) of pelvic floor and abdominal musculature to facilitate relaxation of muscles; (II) therapeutic exercises to promote range of motion, improve mobility/flexibility and strengthen weak muscles; (III) biofeedback to facilitate strengthening and relaxation of pelvic floor musculature; (IV) neuromodulation for pelvic floor muscle relaxation and pain relief. GUPI questionnaires were collected at initial evaluation and after the 10th visit. Higher scores reflect worse symptoms. Previous validation of the GUPI calculated a reduction of 7 points to robustly predict being a treatment responder (sensitivity 100%, specificity 76%) and a change in 4 points to predict modest response. Data are presented as medians (ranges). Results: A total of 10 patients completed 10 visits, and the remaining four patients completed between 5 and 9 visits. The median National Institute of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) score at initial evaluation was 30.8 [16-39] and decreased to 22.2 [7-37] at the tenth visit. Five of the 10 patients (50%) in the study had a reduction of greater than 7 points indicating a robust treatment response, and two (20%) had a change of greater than 4 indicating moderate response. Three patients (30%) did not have any meaningful change in NIH-CPSI and the remaining four are in the process of completing 10 sessions. Duration of therapy appears to predict treatment response. Longer duration has better response. Conclusions: Male CPPS is difficult to treat and often requires a multimodal approach. Based on the results of our pilot study, pelvic floor rehabilitation may be an effective treatment option for select patients. A larger study with a control group is needed to validate the routine use of pelvic floor rehabilitation in men with CPPS and predict characteristics of men who would respond to therapy. PMID- 29184792 TI - Significance of positive semen culture in relation to male infertility and the assisted reproductive technology process. AB - There are currently no WHO guidelines on the indications for semen culture; however, semen cultures are performed in the evaluation of male infertility and the assisted reproductive technology (ART) process. The relevance and significance of positive semen cultures is widely debated in the literature, with no current consensus on the usefulness of this test in relation to male infertility. We review the pathogenic mechanisms of potentially pathogenic bacteria, general bacteria, urethral flora, and skin flora on sperm parameters. We also present, possible routes of semen contamination, measures to reduce contamination, and the clinical significance of culture contamination. First, it is critical to distinguish round cells in semen as leukocytes from immature germ cells. Second, it is critical to distinguish leukocytospermia from infected semen in order to guide management. PMID- 29184793 TI - Management of the small renal mass. AB - The increasing use of cross-sectional imaging has led to an increase in the diagnosis of incidental small renal masses (SRMs). About 20% of such masses are benign, while a significant proportion of malignant SRMs demonstrate slow growth kinetics and non-aggressive histologic features. Given these characteristics, lesions that were traditionally treated surgically are increasingly managed with less aggressive approaches. Further contributing to the evolving management paradigm is accumulating evidence supporting the safety of active surveillance and the efficacy of percutaneous renal mass biopsy in guiding management decisions. This review first discusses the epidemiology and diagnostic work-up of SRMs. The available management options are then examined, with emphasis placed on the clinical factors considered in selecting an appropriate approach. The existing evidence and long-term outcomes of each strategy are discussed. Finally, an overview of the current paradigm for the management of a patient with a SRM is provided. The goal is to provide physicians with the necessary understanding to appropriately manage this increasingly common condition. PMID- 29184795 TI - Amniotic therapeutic biomaterials in urology: current and future applications. AB - To examine the rationale and applications of amniotic tissue augmentation in urological surgery. Published literature in English-language was reviewed for basic science and clinical use of amniotic or amnion-chorionic tissue in genitourinary tissues. Basic science and animal studies support the likely benefit of clinical applications of amnion-derived tissues in a variety of urologic interventions. The broad number of properties found in amniotic membrane, coupled with its immunologically privileged status presents a number of future applications in the urological surgical realm. These applications are in their clinical infancy and suggest that further studies are warranted to investigate the use of these products in a systematic fashion. PMID- 29184794 TI - Should we expand the indications for varicocele treatment? AB - Current guidelines suggest that treatment of varicocele should be considered in patients with clinically palpable disease and abnormal semen parameters. However, the clinicians are often challenged with the decision whether to treat varicocele in patients with testicular pain or low testosterone levels. Moreover, varicocele is highly associated with DNA fragmentation due to the oxidative stress and it has been demonstrated that surgical repair of varicocele ameliorates oxidative stress markers and consequently the sperm DNA integrity. These new markers could have an adjunctive role to standard semen parameters especially when normal semen analysis is found in adult men with conventional methods. This review presents a contemporary overview of the rationale for varicocele treatment, as well as of the relationship between varicocele and other novel parameters such as DNA fragmentation index and reactive oxygen species. We will also discuss data from several recent series demonstrating that surgical treatment and especially microsurgical approach could resolve testicular pain, increase testosterone levels and fertility rate both in patients with non-obstructive azoospermia as well as in normozoospermia men. The correlation with progressive testicular failure will be also examined. We hope that this overview will provide clinicians with an evidence-based approach to managing these unanswered and conflicting topics. PMID- 29184796 TI - Oncofertility in sarcoma patients. AB - Treatment for sarcoma can significantly decrease fertility, both due to the irradiation of gonads, and the impact of chemotherapy on gametogenesis. Infertility in cancer survivors causes significant regret and decreased quality of life in their adulthood. As this cancer mainly affects children and young adults, fertility preservation is an essential part of survivorship care, however it remains one of the least implemented services in adolescent and young adult cancer patients. Success of fertility preservation is highly dependent on the referral prior to oncologic treatment. Early patient counseling with possible consult with oncofertility specialists should be offered to every oncologic patient in reproductive age or younger. There are several options available and in continuous evolution for fertility preservation. Cryopreservation of sperm and oocytes constitutes nowadays the standard of care, and should be offered to all patients. Other methods currently under development will potentially bring in the future reliable options for fertility preservation in a wider range of patients, such as those in pre-pubertal age at the time of diagnosis, or with an insufficient sperm count for semen banking. These include testicular sperm extraction (TESE), autologous ovarian tissue transplant, and in vitro maturation of gametes. Novel therapies such as molecular-targeted agents offer a safer toxicity profile regarding fertility, but further research is required to evaluate their impact on the long term, both alone and in combination therapies. Difficulties to access fertility preservation and its costs remain a significant impediment for many patients in need. Warranting access to all sarcoma patients should be a priority in all healthcare professionals involved in their care. PMID- 29184798 TI - Successful management of cavernosal artery pseudoaneurysm using microcoil embolization. AB - Erectile dysfunction (ED) is a common condition among men and has several causes. Among men under the age of 40, pelvic or perineal trauma is the most common cause of ED. Pelvic or perineal trauma often results in arterial injury as the likely mechanism of ED. We present the case of a 14-year-old male diagnosed with a pseudoaneurysm causing arteriogenic ED secondary to blunt force trauma to the perineum. We successfully managed arteriogenic ED with superselective embolization using microcoils. We also conclude through a review of the literature that microcoil and Gelfoam yield similar outcomes. We believe that it is important for urologists to be familiar with the various treatment techniques used by interventional radiologists in order to properly manage post-traumatic arteriogenic ED. PMID- 29184799 TI - Liposarcoma in the spermatic cord presenting as an inguinal swelling. AB - Liposarcoma in the spermatic cord is a rare condition with an incidence of 1 per 2.5 million. The condition can present as paratesticular pain and a quick diagnosis is important in order to ensure proper treatment and to improve the prognosis. We describe a case of a 69-year-old man who suffered from long-lasting swelling in the inguinal area and experienced increasing pain through a period of 2 weeks. Due to increasing pain and fast growing swelling, an exploration of the inguinal area was performed and peroperatively a tumour in the spermatic cord was found. Subsequent histological examination revealed a de-differentiated liposarcoma. PMID- 29184797 TI - Etiologic classification, evaluation, and management of hematospermia. AB - Hematospermia is defined by the presence of blood in the semen typically occurring in men younger than 40 years of age. Symptoms can occur due to a multitude of reasons, but are usually benign and self-limiting, requiring no additional treatment or evaluation. Despite this, the condition often impairs quality of life due to associated anxiety and must be taken seriously by the patient and the physician, particularly if recurrent, refractory, and painful. The etiology of hematospermia can be classified into inflammatory, infectious, lithiasis, cystic, obstructive, tumoral, vascular, traumatic, iatrogenic, and systemic origin. Alternatively, it can also be divided into subcategories based on anatomical origins such as prostate, bladder, spermatic cord, seminal vesicles, or epididymis. A complete history and physician examination, laboratory testing, and a variety of invasive and non-invasive imaging and instrumentation modalities can help to identify and treat the underlying pathology promptly.

PMID- 29184805 TI - Growth perturbations from stimulant medications and inhaled corticosteroids. AB - Stimulant medications for the treatment of attention deficit hyperactivity disorder (ADHD) and inhaled corticosteroids (ICS) for the treatment of asthma are two classes of medications that are commonly prescribed in pediatrics. Among other adverse effects of these medications, growth attenuation has long been a focus of investigation. With stimulants, growth deficits of 1-1.4 cm/year have been observed in the short term, mainly in the first 2 years of treatment, in a dose-dependent manner. Long-term studies on stimulants have reported divergent effects on growth, with many studies showing no clinically significant height deficits by adulthood. The study that followed the largest cohort of children on stimulants, however, reported an overall adult height deficit of 1.29 cm in subjects who had received stimulant medications, with mean adult height deficit of 4.7 cm among those taking the medication consistently. With ICS use, mild growth suppression is seen in the short term (particularly in the first year of therapy) with growth rates reduced by 0.4-1.5 cm/year. Available current evidence indicates that the impact of ICS use on adult height is not clinically significant, with effects limited to 1.2 cm or less. There is significant individual variability in growth suppression with ICS use, with the specific pharmacologic agent, formulation, dose exposure, age, puberty, medication adherence, and timing of administration being important modifying factors. Based on currently available evidence, the therapeutic benefits of ICS for management of asthma and stimulant medications for management of ADHD outweigh the potential risk for growth suppression. Strategies to minimize growth attenuation and other potential adverse effects of these medications include using the lowest efficacious dose, frequent assessments and dose titration. Particular vigilance is essential with concomitant use of multiple medications that can attenuate growth and to evaluate for potential adrenal insufficiency from ICS use. PMID- 29184806 TI - Polycystic ovary syndrome in adolescence: diagnostic and therapeutic strategies. AB - Controversy continues about the underlying etiopathogenesis, diagnostic criteria, and recommendations for polycystic ovary syndrome (PCOS) in adolescents. Recent literature has recognized these deficiencies and evidence based expert recommendations have become more available. The purpose of this chapter is to offer primary care providers a practical understanding and approach to the diagnosis and treatment of PCOS in adolescents. Although the presence of polycystic ovary morphology (PCOM) is included as a key diagnostic criterion of PCOS in adults, it is currently not recommended for the diagnosis in adolescents. As such, the diagnosis of PCOS in adolescents currently hinges on evidence of ovulatory dysfunction and androgen excess. Recommended evidence of ovulatory dysfunction includes: consecutive menstrual intervals >90 days even in the first year after menstrual onset; menstrual intervals persistently <21 or >45 days 2 or more years after menarche; and lack of menses by 15 years or 2-3 years after breast budding. Recommended evidence of androgen excess include: moderate to severe hirsutism; persistent acne unresponsive to topical therapy; and persistent elevation of serum total and/or free testosterone level. Importantly, a definitive diagnosis of PCOS is not needed to initiate treatment. Treatment may decrease risk of future comorbidity even in the absence of a definitive diagnosis. Deferring diagnosis, while providing symptom treatment and regular/ frequent follow-up of symptomology, is a recommended option. The treatment options for PCOS should be individualized to the presentation, needs, and preferences of each patient. Goals of treatment are to improve quality of life and long-term health outcomes. Lifestyle modifications remain first-line management of overweight and obese adolescents with PCOS. Combined oral contraceptives (COC) are first line pharmacotherapy for management of menstrual irregularity and acne, and metformin is superior to COCs for weight reduction and improved dysglycemia. COCs and metformin have similar effects on hirsutism, but often need to be paired with other treatment modalities to achieve further improvement of cutaneous symptoms. Clinicians should be cognizant that PCOS is associated with significant metabolic and psychological comorbidity and screen for these issues appropriately. PMID- 29184807 TI - Zoledronic acid in pediatric metabolic bone disorders. AB - Zoledronic acid (ZA), a highly potent intravenous bisphosphonate (BP), has been increasingly used in children with primary and secondary osteoporosis due to its convenience of shorter infusion time and less frequent dosing compared to pamidronate. Many studies have also demonstrated beneficial effects of ZA in other conditions such as hypercalcemia of malignancy, fibrous dysplasia (FD), chemotherapy-related osteonecrosis (ON) and metastatic bone disease. This review summarizes pharmacologic properties, mechanism of action, dosing regimen, and therapeutic outcomes of ZA in a variety of metabolic bone disorders in children. Several potential novel uses of ZA are also discussed. Safety concerns and adverse effects are also highlighted. PMID- 29184808 TI - Recovery of steroid induced adrenal insufficiency. AB - Secondary adrenal insufficiency can result from insufficient stimulation of the adrenal glands due to inadequate secretion or synthesis of adrenocorticotropic hormone (ACTH). This can be caused by hypopituitarism, central nervous system injury (tumors, radiation, and surgery) or long-term glucocorticoid therapy. Glucocorticoids were introduced in the 1950s, and have been used for their anti inflammatory and other pharmacological effects, and also as replacement therapy for adrenal insufficiency. However, chronic glucocorticoid use may lead to suppression of the hypothalamic pituitary adrenal axis through negative feedback. This may lead to secondary adrenal insufficiency. Typically, the hypothalamic pituitary adrenal axis recovers after cessation of glucocorticoids, but the timing of recovery can be variable and can take anywhere from 6-12 months. Understanding the effect of exogenous glucocorticoids on the hypothalamic pituitary adrenal axis, recovery of the axis, and tests used to assess the recovery, are crucial to avoid prescribing unnecessary steroid replacement or missing a critical diagnosis with detrimental consequences. PMID- 29184809 TI - Review of Prader-Willi syndrome: the endocrine approach. AB - Prader-Willi syndrome (PWS) is a complex genetic disorder with implications on the endocrine and neurologic systems, metabolism, and behavior. Early in life, PWS is characterized by hypotonia and failure to thrive, followed by obesity and hyperphagia. Patients with PWS develop hypothalamic dysfunction which may lead growth hormone deficiency (GHD), hypogonadism, hypothyroidism, adrenal insufficiency, and poor bone mineral density (BMD). In addition to hypothalamic dysfunction, individuals with PWS have increased risk for obesity which may be complicated by metabolic syndrome and type 2 diabetes mellitus (T2DM). In this paper, we will review the current literature pertaining to the endocrine concerns of PWS and current recommendations for screening and management of these conditions. PMID- 29184810 TI - Ophthalmic manifestations of endocrine disorders-endocrinology and the eye. AB - Disorders of the endocrine system usually manifest in a multi-organ fashion. More specifically, many endocrinopathies become apparent in the eye first through a variety of distinct pathophysiologic disturbances. The eye provides physicians with valuable clues for the recognition and management of numerous systemic diseases, including many disorders of the endocrine pathway. Recognizing ophthalmic manifestations of endocrine disorders is critical not only for rapid diagnosis and treatment, but also to prevent significant morbidity and mortality. In this review, we discuss relevant ophthalmic findings associated with key disorders of the pancreas, thyroid gland, and hypothalamic-pituitary axis, as well as with multiple hereditary endocrine syndromes. We have chosen to focus on diabetes mellitus (DM), Graves' ophthalmopathy, pituitary tumors, and some less common disorders that underscore the unique relationship between the eye and the endocrine system. PMID- 29184811 TI - Dermatologic manifestations of endocrine disorders. AB - The skin serves as a window for clinicians to understand, diagnose, and monitor endocrine disease. Dermatologic manifestations of endocrinopathies contribute significantly to an individual's health and quality of life. In this review, we outline various disorders of the hypothalamic-pituitary axis, thyroid gland, pancreas, adrenal gland, and androgen axis as well as hereditary endocrine syndromes. In acromegaly, glycosaminoglycan deposition contributes to a thickening of skin and soft tissue, which manifests as coarsening and enlargement of facial and acral structures. Stimulation of the thyrotropin receptor in hyperthyroidism results in mesenchymal tissue proliferation and consequent pretibial myxedema; other associated cutaneous features include onycholysis, and hyperhidrosis. Individuals with hypothyroidism exhibit cold, dry skin and brittle hair as well as a jaundice-like appearance due to carotene excess. The cutaneous features of diabetes mellitus (DM), mediated to a large extent by hyperglycemia and hyperinsulinemia, include necrobiosis lipoidica diabeticorum (NLD), diabetic dermopathy, and acanthosis nigricans. Pediatric patients with Cushing's syndrome almost invariably present with truncal obesity and growth retardation; disruption of collagen formation and the catabolic effects of hypercortisolism result in skin atrophy and purple abdominal striae. In patients with Addison's disease, generalized hyperpigmentation, secondary to elevated levels of melanocyte stimulating hormone (MSH), is most prominent in sun-exposed areas. Due to hyperandrogenism, individuals with polycystic ovarian syndrome (PCOS) often exhibit hirsutism, acne vulgaris, and androgenetic alopecia. In multiple endocrine neoplasia (MEN) syndromes, specific gene mutations may lead to angiofibromas, lichen amyloidosis, and ganglioneuromas. Disruptions of immune regulation result in autoimmune polyglandular syndromes (APS) and associated clinical features including chronic mucocutaneous candidiasis, vitiligo, and alopecia areata. This paper highlights the underlying pathophysiology, dermatologic manifestations, and treatment of the aforementioned endocrine disorders. PMID- 29184812 TI - Fertility counseling and preservation: considerations for the pediatric endocrinologist. AB - Infertility is a distressing consequence of numerous pediatric medical conditions and treatments. The field of pediatric fertility preservation has expanded rapidly over the past decade, and clinical guidelines emphasize the importance of discussing infertility risk and fertility preservation options with patients and families in a timely manner. Understanding the various mechanisms and presentations of fertility issues across diagnoses is imperative to provide counseling to patients and families, and identify individuals who may benefit from fertility preservation. The goals of this manuscript are to outline current fertility preservation options in pediatrics, review populations at-risk for infertility that are seen in pediatric endocrinology, and discuss other important issues related to fertility preservation including ethical considerations. PMID- 29184813 TI - Disorders/differences of sex development (DSDs) for primary care: the approach to the infant with ambiguous genitalia. AB - The initial management of the neonate with ambiguous genitalia can be a very stressful and anxious time for families, as well as for the general practitioner or neonatologist. A timely approach must be sensitive and attend to the psychosocial needs of the family. In addition, it must also effectively address the diagnostic dilemma that is frequently seen in the care of patients with disorders of sex development (DSDs). One great challenge is assigning a sex of rearing, which must take into account a variety of factors including the clinical, biochemical and radiologic clues as to the etiology of the atypical genitalia (AG). However, other important aspects cannot be overlooked, and these include parental and cultural views, as well as the future outlook in terms of surgery and fertility potential. Achieving optimal outcomes requires open and transparent dialogue with the family and caregivers, and should harness the resources of a multidisciplinary team. The multiple facets of this approach are outlined in this review. PMID- 29184814 TI - Hypoglycemia in the preterm neonate: etiopathogenesis, diagnosis, management and long-term outcomes. AB - Glucose, like oxygen, is of fundamental importance for any living being and it is the major energy source for the fetus and the neonate during gestation. The placenta ensures a steady supply of glucose to the fetus, while birth marks a sudden change in substrate delivery and a major change in metabolism. Hypoglycemia is one of the most common pathologies encountered in the neonatal intensive care unit and affects a wide range of neonates. Preterm, small for gestational age (GA) and intra-uterine growth restricted neonates are especially vulnerable due to their lack of metabolic reserves and associated co-morbidities. Nearly 30-60% of these high-risk infants are hypoglycemic and require immediate intervention. Preterm neonates are uniquely predisposed to developing hypoglycemia and its associated complications due to their limited glycogen and fat stores, inability to generate new glucose using gluconeogenesis pathways, have higher metabolic demands due to a relatively larger brain size, and are unable to mount a counter-regulatory response to hypoglycemia. In this review we will discuss the epidemiology; pathophysiology; clinical presentation; management and neurodevelopmental outcomes in affected infants and summarize evidence to develop a rational and scientific approach to this common problem. PMID- 29184815 TI - Transient hypothyroidism in the newborn: to treat or not to treat. AB - Transient congenital hypothyroidism (CH) refers to a temporary deficiency of thyroid hormone identified after birth, with low thyroxine (T4) and elevated thyrotropin (TSH), which later recovers to improved thyroxine production, typically in first few months of infancy. Approximately 17% to 40% of children diagnosed with CH by newborn screening (NBS) programs were later determined to have transient hypothyroidism. Causes of transient CH are prematurity, iodine deficiency, maternal thyrotropin receptor blocking antibodies, maternal intake of anti-thyroid drugs, maternal or neonatal iodine exposure, loss of function mutations and hepatic hemangiomas. The classic clinical symptoms and signs of CH are usually absent immediately after birth in vast majority of infants due to temporary protection from maternal thyroxine. NBS has been largely successful in preventing intellectual disability by early detection of CH by performing thyroid function tests in infants with abnormal screening results. In this review we present the evidence for decision making regarding treatment vs. withholding treatment in infants with transient CH and present a rational approach to identifying transient CH based on American Academy of Pediatrics (AAP) recommendation. PMID- 29184816 TI - Type 1 diabetes: where are we in 2017? AB - Type 1 diabetes mellitus is a chronic state of insulin deficiency which results from destruction of beta cells by the immune system. The long term microvascular and macrovascular complications can be devastating. Since the discovery of insulin almost 100 years ago new medical therapies have improved the long-term survival for people with type 1 diabetes. Each year we come closer to discovering a cure but much work still needs to be done to eliminate this disease. PMID- 29184817 TI - Role of a registered dietitian in pediatric type 1 and type 2 diabetes. AB - Type 1 and type 2 diabetes are complex, chronic diseases that are best managed by a multidisciplinary care team. Type 1 diabetes is most commonly diagnosed in the pediatric population, although the prevalence of type 2 diabetes in youth is increasing rapidly. A registered dietitian (RD) is a critical member of the diabetes team who provides focused nutrition education from diagnosis and throughout routine follow-up care. Specifically in the pediatric population, the RD also assesses growth and development, as well as eating behaviors, food choices and meal patterns. Based on a review of research, ongoing support from an RD improves glycemic control and delays onset of diabetes complications. In addition, dietitian-led nutrition education helps better manage lipid levels and aids in weight management. A sample model describing RD involvement in a pediatric diabetes care team is discussed in further detail. PMID- 29184818 TI - Transition of care for patients with type 1 diabetes mellitus from pediatric to adult health care systems. AB - Planning for the transition from pediatric to adult healthcare is broadly understood to be beneficial to the quality of care of patients with chronic illness. Due to the level of self-care that is necessary in the maintenance of most chronic diseases, it is important that pediatric settings can offer support during a time when adolescents are beginning to take more responsibility in all areas of their lives. Lack of supportive resources for adolescents with chronic conditions often results in both decreased access to care and impaired health and function likely leading to increased medical costs later. Additionally, fundamental differences in health care delivery exist between pediatric and adult care settings. There is limited empiric data and information on best practices in transition care. In this article we address the importance of bridging pediatric and adult care settings and highlight the challenges and successes of the implementation of the young adult transition clinic program for patients with type 1 diabetes at our facility. We provide recommendations for further research and program implementation with the transition population. PMID- 29184819 TI - Psychosocial aspects of diabetes management: dilemma of diabetes distress. AB - Diabetes mellitus (DM) is a debilitating chronic illness with complex pathophysiological, psychological, and quality of life (QoL) implications creating a constant state of turbulence. Some of these interconnections are apparent to healthcare providers and are easily addressed in a routine diabetic clinical care. However, a large number of these hidden factors that interplay with each other and impact on the physical outcomes of DM goes unnoticed by health care providers. This is a frustrating and lonely predicament for DM patients making it very difficult for them to manage their illness well. At times these patients are mislabeled as "difficult patients". In other cases they are considered to have and unnecessarily treated for psychiatric illness like depression, other mood or anxiety spectrum disorders which they may not need. In recent years clinical researcher are making strides in understanding the emotional distress a DM patient may feel and the factors contributing or perpetuating diabetes distress. This article focuses on understanding the diabetes distress and how it impacts our patients, how to screen, assess, treat and eventually prevent it from happening. The paper also attempt to bring out the major differences between diabetes distress and common psychiatric comorbidities of DM including but not limiting to major depressive disorder and other depression spectrum disorders. PMID- 29184820 TI - Metabolic syndrome in children and adolescents. AB - Prevalence of metabolic syndrome in children and adolescents is increasing, in parallel with the increasing trends in obesity rates. Varying definitions of this syndrome have hindered the development of a consensus for the diagnostic criteria in the pediatric population. While pathogenesis of metabolic syndrome is not completely understood, insulin resistance and subsequent inflammation are thought to be among its main mechanistic underpinnings. Overweight and obesity are cardinal features, along with abnormal glucose metabolism, dyslipidemia, and hypertension. Other disorders associated with metabolic syndrome include fatty liver, polycystic ovarian syndrome (PCOS), and pro-inflammatory states. Prevention and management of this condition can be accomplished with lifestyle modifications, behavioral interventions, pharmacological and surgical interventions as needed. PMID- 29184821 TI - Approach to hypoglycemia in infants and children. AB - Hypoglycemia is a heterogeneous disorder with many different possible etiologies, including hyperinsulinism, glycogen storage disorders, fatty acid disorders, hormonal deficiencies, and metabolic defects, among others. This condition affects newborns to adolescents, with various approaches to diagnosis and management.

AB - Aim: The aim of the study was to compare the clinical and microbiological efficacy of Group I-delmopinol dentifrice, Group II-chlorhexidine, and Group III triclosan-containing regularly used control dentifrice on plaque formation and gingivitis. Materials and Methods: A total of 45 healthy volunteer students fulfilling the inclusion criteria are recruited for this randomized control parallel study. All the individuals were randomly assigned into 3 groups depending on the dentifrice prescribed. After the selection of individuals, thorough scaling and polishing were performed for all the individuals, and in a 4 days' washout period, they were refrained from regular oral hygiene maintenance and 0.9% NaCl (normal saline) rinse was prescribed to obtain plaque regrowth. Microbiological morphotypes were assessed using darkfield microscope. Statistical Analysis: The data were analyzed using the SPSS-software 19.00 program. The intragroup comparison of clinical parameters was done using Kruskal-Wallis ANOVA test, and intergroup comparison was done by Mann-Whitney U-test. The intragroup comparison of clinical parameters including modified staining index, the supragingival microbiota such as cocci, bacilli, and spirochetes scores was done at various study intervals using one-way ANOVA, and intergroup comparison was done using Tukey's multiple post hoc test. Results: The results showed that statistically significant correlation between Group II and Group III at 15 and 30 days and between Group I and Group II at 30 days with cocci and bacilli but not spirochetes. Conclusion: Group II showed better plaque and gingivitis reduction compared to other active groups. To validate the results of the present study, further long-term studies with larger sample size and evaluation using known and proven study designs on gingivitis patients are needed. PMID- 29184823 TI - A prospective randomized controlled study: Theophylline on oxidative stress and steroid sensitivity in chronic obstructive pulmonary disease patients. AB - Objective: Oxidative stress is involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). Corticosteroid fails to suppress inflammation and oxidative stress due to steroid resistance. Theophylline has an effect on histone deacetylase (HDAC) activity and improves steroid sensitivity in COPD. Given changes in oxidative stress associated with diminished corticosteroid effects, a clinical study in which antioxidants and free radicals are estimated can suggest a correlation between antioxidants, theophylline, and corticosteroid sensitivity. Materials and Methods: A randomized controlled study was conducted in 60 participants divided into 4 groups: Group I (controls) - 15 normal healthy volunteers, Group II - COPD patients who received theophylline 300 mg + salbutamol 8 mg, Group III - patients who inhaled budesonide 400 MUg + salbutamol 8 mg, and Group IV - theophylline 300 mg + inhaled budesonide 400 MUg + salbutamol 8 mg 12 weeks. Blood samples were collected at the time of diagnosis and at 4-week interval for 3 months from all the groups and antioxidant parameters, spirometric % forced expiratory volume in 1 s (FEV1) were measured. Results: The mean difference between groups was analyzed using one-way ANOVA. There was a significant increase in antioxidant enzymes such as catalase, glutathione (GSH) serum transferase, (P < 0.05), reduced GSH, and superoxide dismutase (P < 0.01) and a significant decrease in lipid peroxidation (P < 0.01) at 12 weeks of the study period. Postbronchodilator FEV1 values have also shown a significant increase at 12 weeks (P < 0.01). Conclusion: Theophylline increases the expression and activity of HDAC and improves steroid sensitivity thereby decreases oxidative stress. Hence, novel therapeutic strategy is therefore the reversal of this corticosteroid resistance by increasing the expression and activity of HDAC achieved using corticosteroids along with theophylline. PMID- 29184824 TI - Smartphone usage and increased risk of mobile phone addiction: A concurrent study. AB - Objective: This study aimed to study the mobile phone addiction behavior and awareness on electromagnetic radiation (EMR) among a sample of Malaysian population.

The study instrument comprised eight segments, namely, informed consent form, demographic details, habituation, mobile phone fact and EMR details, mobile phone awareness education, psychomotor (anxious behavior) analysis, and health issues. Frequency of the data was calculated and summarized in the results. Results: Totally, 409 respondents participated in the study. The mean age of the study participants was 22.88 (standard error = 0.24) years. Most of the study participants developed dependency with smartphone usage and had awareness (level 6) on EMR. No significant changes were found on mobile phone addiction behavior between the participants having accommodation on home and hostel. Conclusion: The study participants were aware about mobile phone/radiation hazards and many of them were extremely dependent on smartphones. One-fourth of the study population were found having feeling of wrist and hand pain because of smartphone use which may lead to further physiological and physiological complication. PMID- 29184825 TI - A comparative evaluation of diclofenac sodium transdermal patch, oral diclofenac sodium with intramuscular injections of diclofenac sodium in patients suffering from oral pain: A randomized control trial. AB - Background: Newer drug delivery systems such as transdermal patches using pain relieving or modifying agents emerged as a mainstream treatment protocol for management of pain on the outpatient basis. The administration of diclofenac 100 mg in the transdermal patch in the patients having dental pain due to periapical/periodontal infections was evaluated. Materials and Methods: Ninety patients of either gender, between 18 and 80 years were divided into 3 groups (Group A - oral medication, Group B - transdermal patch, Group C - intramuscular group). Patients at the Dental Department with pain from periapical/periodontal pathologies were explained about the procedure of analgesia. With written consent, 100 mg diclofenac sodium transdermal patches were prescribed to patients who opted their use in pain control for 2 consecutive days. A visual analog scale was provided for all patients assessing the pain intensity during the study. Results: Significant difference in the mean percentage reduction in visual analog scale (VAS) score among the three groups at day 1 and 2 (P < 0.001). Post hoc test showed that intramuscular (IM) and oral groups had significantly higher mean VAS score than patch group. Conclusion: Diclofenac administered through oral and IM routes showed significant improvement in pain relief when compared to the transdermal route. However, diclofenac transdermal patches have shown significant improvement in VAS score between the baseline and consecutive days and can be used in mild pain with lower adverse events. PMID- 29184826 TI - Isolation and identification of probiotic Lactobacillus from local dairy and evaluating their antagonistic effect on pathogens. AB - Objective: Probiotics such as lactobacilli prevent the development of a wide range of human and animal's pathogens. The aim of this study was evaluation of antagonistic effect of isolated lactobacilli from local dairy products against three standard strains of Staphylococcus aureus, Bacillus subtilis, and Pseudomonas aeruginosa. Materials and Methods: Twenty samples of local dairy products including cow milk, buffalo milk, cheese, and yogurt were collected from different areas of Ahwaz city. Antimicrobial disc diffusion method was applied on S. aureus (ATCC-6538), B. subtilis (ATCC-12711), and P. aeruginosa (ATCC-27853). Antimicrobial effects of isolates were evaluated by disc diffusion test on Mueller-Hinton agar medium plated with three pathogens. Results: Obtained results showed that only three strains of isolated lactobacilli of local dairy samples had inhibitory effects on understudy pathogens including Lactobacillus alimentarius, Lactobacillus sake, and Lactobacillus collinoides. All three isolates showed moderate activity (inhibition zone <15 mm) except of L. collinoides and L. alimentarius that had relatively strong activity (inhibition zone >=15 mm) against P. aeruginosa and B. subtilis, respectively. Conclusion: These bacteria can be raised for the production of various kinds of food, pharmaceutical products, and functional foods. PMID- 29184827 TI - Development of a binary carrier system consisting polyethylene glycol 4000 - ethyl cellulose for ibuprofen solid dispersion. AB - Background and Objective: One of the established strategies to improve solubility and dissolution rate of poorly water-soluble drugs is solid dispersion (SD). Polyethylene glycol (PEG) is used as common carrier despite its stability problem which may be overcome by the addition of hydrophobic polymer. The present research aimed to develop an SD formulation with ibuprofen, a poor water-soluble BCS Class II drug as active pharmaceutical ingredient (API) and PEG 4000-ethyl cellulose (EC) as binary carrier. Methods: Melt mixing SD method was employed using a ratio of API: binary carrier (1:3.5 w/w) (SDPE). Another SD was prepared using only PEG (SDP) as a carrier for comparative study. The developed formulation was evaluated using optical microscopy, scanning electron microscopy (SEM), determination of moisture content, differential scanning calorimetry (DSC), in vitro dissolution test, attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR) and flow properties. Results: SEM and DSC indicated the conversion of crystalline ibuprofen to fine partly amorphous solid dispersion, which was responsible for the increase in dissolution rate of SD than a physical mixture. The release characteristics within 1 h from the higher to the lower value were the SDPE> SDP> physical mixture. Flow property evaluation using the angle of repose showed no difference between SD and PM. However, by Carr index and Hausner ratio, the flow properties of SDPE was excellent. Conclusion: The SD formulation with the PEG 4000-EC carrier can be effective to enhance in vitro dissolution of ibuprofen immediate release dosage form. PMID- 29184828 TI - Radioprotective effect of hesperidin on reducing oxidative stress in the lens tissue of rats. AB - Introduction: Oxidative stress is a common factor in cataract. Considering the antioxidant properties of hesperidin as a flavanone glycoside from the flavonoid family with radioprotective effect, this study aimed to determine the protective effect of this flavanone glycoside on reducing oxidative stress in the eye lens tissue of mature rats caused by gamma irradiation. Materials and Methods: A total of 48 adult rats were randomly divided into six groups, namely, control, Dimethyl sulfoxide (DMSO), hesperidin, radiation, radiation + DMSO, and radiation + hesperidin. 15 Gy irradiation was carried out using Cobalt-60 teletherapy instrument with a source-to-surface distance of 80 cm at a dose rate of 98.5 cGy/min. 2 days following irradiation, we removed the rats' lenses and analyzed them to determine the effects of hesperidin. Results: The comparison of control and intervention groups after irradiation showed that malondialdehyde (MDA) level in the lens tissue was significantly higher in the irradiation groups than the control group. Furthermore, a significant difference between radiation and radiation + hesperidin groups were observed. The level of glutathione (GSH) in the lens tissue was significantly lower in the irradiation groups compared to the control group. Nonetheless, significant elevation of GSH in the radiation + hesperidin group compared to radiation group was seen. Conclusions: Radiation exposure reduced GSH and enhanced MDA levels in the lens tissue. However, GSH and MDA levels were modulated after hesperidin consumption. These results show the antioxidative properties of hesperidin in the lens and demonstrated that radiation complications such as cataract can be reduced by hesperidin through reducing oxidative stress. PMID- 29184829 TI - Platelets and Their Pathways in Dentistry: Systematic Review. AB - Advancing research in medicine and technology has benefitted the mankind immensely with its contribution toward an improved life quality and increased life expectancy. The inability of a human body to autoregenerate has resulted in an increased demand for newer and healthier tissues and organs. Therefore, the restoration of naturally replicated tissue components has become a subject of interest for the scientific community lately. There was felt an intense quest for promoting strategies that could restore tissue regeneration and fuel the field of regenerative medicine. It was then the role of platelets was accounted for its wound healing and regenerative effects. Consequently, the use of platelet concentrates to improve wound healing, and bone formation was explored, which was considered to be possible because platelets contain high quantities of growth factors which would be able to stimulate cell proliferation, matrix remodeling, and angiogenesis, thereby establishing a new era of research with the successful application of innovative medical therapies focused on healing damaged tissues or regenerate the affected organs. PMID- 29184830 TI - Orofacial Bacterial Infectious Diseases: An Update. AB - Objectives: Most of the oral infections with odontogenic origin are very common and can be treated by tooth extraction, endodontic therapy, or surgical treatment. Other infectious lesions are the manifestations of systemic diseases such as tuberculosis and syphilis. Skin and underlying subcutaneous tissue, fascia, or muscle is also involved with infectious diseases which range from superficial epidermal infections to very serious necrotizing fasciitis. Materials and Methods: An extensive literature in PubMed, Google Scholar, and Scopus search was performed from 1980 to 2017. All related articles were analyzed. Results: Most oral infections have odontogenic origin. Skin and the underlying subcutaneous tissue, fascia, or muscles are also involved with infectious diseases which range from superficial epidermal infections to very serious necrotizing fasciitis. Conclusions: These facts prove that the interaction between the oral cavity, face skin, and the other organs can risk the people's life. The establishment of a correct diagnosis and recognition of clinical findings are the crucial steps to support and improve professional orofacial health status. PMID- 29184831 TI - A Cone Beam Computed Tomography of the Root Canal Morphology of Maxillary Anterior Teeth in an Institutional-Based Study in Chennai Urban Population: An In vitro Study. AB - Aim: This study aims to investigate the root canal anatomy of human extracted permanent maxillary anterior teeth in patients reporting to our dental institution in Chennai using cone beam computed tomography (CBCT). Materials and Methods: A total of 285 maxillary anterior teeth comprising of 100 central incisors, 85 lateral incisors, and 100 canines extracted from various patients reporting to our institution were studied. The number of roots and number of canals were assessed; following which, the root canal anatomy of each tooth was evaluated for the canal pattern using CBCT. The collected data were analyzed using IBM. SPSS statistics software 23.0 version. Results: All the teeth examined were observed to be single rooted. All maxillary central incisors displayed Type I (100%) pattern whereas maxillary laterals and canines displayed canal variations. In maxillary laterals, Type I pattern (98%) was most prevalent followed by Type II (2%) configuration. Maxillary canines revealed a predominant Type I (96%) canal pattern followed by Type II (3%) and Type III (1%). Conclusion: A varied root canal anatomy was observed in maxillary anterior teeth among Chennai urban population in this institutional-based study. The most frequent canal pattern reported in the maxillary anterior dentition was Type I. Type II was observed in both maxillary lateral incisors and maxillary canines whereas Type III canal configuration was reported only in maxillary canines. PMID- 29184832 TI - Cross-cultural Adaptation and Psychometric Properties of the Indonesia Version of the Scale of Oral Health Outcomes for 5-Year-Old Children. AB - Objective: Oral health-related quality of life (OHRQoL) questionnaires have been administered to children older than 6 years. Currently, the scale of oral health outcomes for 5-year-old children (SOHO-5) has been used to determine the OHRQoL through self-reports and parental proxy reports of children aged <6 years. This study was conducted to estimate the psychometric reliability and validity after adapting the SOHO-5 to the Indonesian language. Materials and Methods: The cross cultural adaptation was tested in children aged 5 years old and their parents. The reliability and validity of the questionnaire were measured among 161 kindergarten children in Jakarta, along with a clinical examination for dental caries. Results: Cronbach's alpha coefficients for internal consistency were 0.89 and 0.86 for child's self-reports and parental reports, respectively. The test retest reliability results were excellent based on repeated administrations in 27 children; the intraclass correlation coefficients were 0.81 and 0.94 for the parental reports and child's self-reports, respectively. No corrected item-total correlation value was lower than 0.30, allowing all items in the instrument to be included for data analyses. The construct validity of the child's self-reports showed that the Indonesian SOHO-5 total score was significantly associated only with the presence of dental caries (P < 0.001). The construct validity of the parental reports described that the SOHO-5 total score was significantly associated with proxy-rated oral health, the child's perceived dental treatment and satisfaction with the child's oral health (P < 0.001). Conclusions: This study showed the Indonesian version of SOHO-5 is a reliable and valid OHRQoL measure for 5-year-old Indonesian children. PMID- 29184833 TI - Comparison of Coronal Leakage in Tooth Preparation with Two Single File Systems and Three Obturation Techniques. AB - Aims and Objectives: Root canal preparation and obturation are of great importance in endodontics. Its purpose is to eliminate pulpal and periradicular disease. The aim of this study was to compare coronal bacterial microleakage in prepared root canals using Neoniti A1 and Reciproc files that obturated with lateral compaction, single cone gutta-percha, and hybrid (tapered cone/lateral compaction) methods. Materials and Methods: In this ex vivo study, a total of 110 single-rooted mandibular first premolars were choose and randomly divided into two study groups A and B (each 45) that one group was prepared with Reciproc and another with Neoniti A1 and negative and positive control groups (each 10). Each group divided into three subgroups of 15 each and obturated using a single cone, lateral compaction, and hybrid (tapered cone/lateral compaction) techniques. For evaluation of coronal leakage, "two-chamber setup" was used. The solution of enterococcus faecalis culture was injected in the upper chamber and incubated. If the bacteria pass through the canal and obturation materials, the lower chamber becomes turbid. TSB medium in the lower chamber (apex) were investigated every day in terms of occurrence of turbidity, and the duration of occurrence of leakage was recorded. The data were analyzed using Chi-square test. Results: Data analysis showed that in each group the difference in percentages between subgroups was statistically significant (P = 0.003). So that the highest and the lowest amount of leakage in both groups were related to lateral compaction and hybrid techniques, respectively. Conclusion: Under the conditions of this study, independent of the instrument used for canal preparation, hybrid method and then single-cone technique, however, were more effective in the prevention of coronal leakage than lateral condensation technique. PMID- 29184834 TI - Knowledge, Attitude, and Practice of Upper-middle Class toward the Importance of a Pediatric Dentist. AB - Aims and Objectives: This study was carried out to assess the knowledge, attitude, and practice of upper middle class toward the importance of a pediatric dentist in the city of Amritsar, Punjab. Materials and Methods: A cross-sectional study was carried out among the parents of children belonging to upper middle class in the city of Amritsar. This proposed study was assessed by the Institutional Ethical Committee (531/IDSR/2016) and their clearance was attained. A total of 950 parents were selected using a convenient sampling technique, and a self-made questionnaire was presented to them. Responses from the parents were evaluated in terms of numbers and percentages and were statistically analyzed using SPSS for Windows release 14.0 (SPSS Inc., Chicago, IL, USA). Differences at the 5% level were accepted as being statistically significant. Results: The results of the study show limited knowledge about a pediatric dentist among the well-educated, well-placed, and economically sound citizens of Amritsar city. Consequently, the attitude and practices among this socioeconomic group are unconstructive and unprepared, respectively. Conclusion: Although the importance of taking a child to a pediatrician is a common practice among the upper and upper-middle classes of the society, it is clear that they do not give the same importance to a pediatric dentist, who is the pediatrician of dentistry. PMID- 29184836 TI - A Comparative Evaluation of Effect of Reinforced Autopolymerizing Resin on the Flexural Strength of Repaired Heat-polymerized Denture Base Resin before and after Thermocycling. AB - Aims and Objective: Denture fractures are a common problem in clinical practice. Despite the use of different reinforcement materials (metal wires, metal plates, and various types of fibers) for denture repairs, recurrent fractures are still common. The purpose of this study was to compare the maximum flexural loads of the heat-polymerized denture base resin when repaired with autopolymerizing resin reinforced with relatively smaller diameter metal wires and glass fibers, before and after thermocycling. Materials and Methods: Heat polymerized rectangular specimens were fabricated and repaired with autopolymerized resin and different reinforcement materials. Stainless steel wires, coaxial wires, beta-titanium wires, and glass fibers were used as reinforcement materials. Metal wires were sandblasted before placing in the center of the specimen along with autopolymerizing resin. Control specimens were repaired without any reinforcements. Intact heat- and self-cure specimens were also prepared for comparison. Half of the specimens of each group were subjected to thermocycle stressing (5 degrees C and 55 degrees C, 30 s dwell time) for 2000 cycles. All the specimens, nonthermocycled as well as thermocycled, were then tested for flexural strength by using 3 point flexural test in Lloyd's Universal testing machine at 5 mm/min crosshead speed. The maximum flexural loads (N) for each specimen were recorded. The readings, thus obtained, were subjected to statistical analysis using two-way ANOVA and Tukey's multiple comparison test. Results: The metal wire reinforcements increased the flexural strength of repaired specimens, whereas, glass fiber reinforcement produced slightly lower flexural strength when compared to those of control specimens, i.e., repair without any reinforcement. The highest flexural strength was demonstrated by specimens repaired with coaxial wire reinforcements (50.01 and 43.77 N before and after thermocycling, respectively). The increase in flexural strength with the use of stainless steel wire (45.12 and 41.56 N) and beta-titanium wire reinforcements (45.54 and 42.61N) was insignificant. Conclusions: Coaxial wire reinforcement produced significantly higher flexural loads than control. Increase in strength with stainless steel wire and beta-titanium wire was insignificant, whereas glass fiber reinforcement reduced the strength. PMID- 29184835 TI - Perceived Stress among French Dental Students and Their Opinion about Education Curriculum and Pedagogy. AB - Objectives: The purpose of this study was to identify the major sources of perceived stress and their relation to a student satisfaction questionnaire about the curriculum and the pedagogy among French dental students. Materials and Methods: All dental students (n = 178) from years 4 to 6 at the University of Montpellier (France) participated in this exploratory survey. In spring 2016, a 3 part questionnaire was distributed during clinical sessions: the first part asked about sociodemographic and living conditions, the second part aimed to assess the students' perceived stress (Dental Environmental Stress questionnaire), and the third part was a satisfaction questionnaire exploring the clinical organization and the teaching methodologies (Student Course Experience Questionnaire). A Spearman's correlation test and a principal component analysis were used to assess the relation between the variables of the questionnaire. Results: The response rate was 99.4%. The most stressful items were "the number of tasks to be performed during clinical practice," "the waiting time before opinion from teachers," and "the administrative part and computer problems." Fifty-four percent of the students claimed to be satisfied with their studies, showing a score of seven or higher. There was a negative correlation between the level of student satisfaction and the level of perceived stress. Conclusion: Although most of the students were globally satisfied with their curriculum, this study highlighted dysfunctions in the clinical education with a level of stress correlated with the student's dissatisfaction. Most of all, students found that examinations were too stressful and that the clinical requested task quotas were overestimated. PMID- 29184837 TI - Effectiveness of an Oral Health Education Program for Obstetrician/Gynecologist Residents at Tufts Medical Center. AB - Aim and Objectives: To assess Tufts Medical Center obstetrician/gynecologist (OB/GYN) residents' knowledge, beliefs, and previous training in oral health and to assess the effect of an oral health educational seminar on their knowledge and beliefs. Materials and Methods: A preseminar questionnaire was distributed to the residents. The same questionnaire was distributed immediately after the seminar and 3 months later. SPSS Version 21 was used for the data analysis. Results: Convenience sample of 25 residents were included in the study. The mean (standard deviation) age of participants was 29.08 (2.47) years. Only 1 (4%) participant reported receiving >8 h previous training in oral health and 7 (28%) reported receiving <1 h of training. The nonparametric Friedman test showed a statistically significant difference between administrations in terms of total score on knowledge-based questions (P < 0.001) and some of the belief-based questions. The post hoc Wilcoxon signed-rank test with Bonferroni correction showed statistically significant improvement in the knowledge-based questions between pre- and post-seminar questionnaire (P = 0.002) and between preseminar and 3-month follow-up (P = 0.003). Conclusions: OB/GYN residents at Tufts Medical Center received limited training in oral health. Their knowledge improved significantly following the oral health educational seminar. Similar training modules can be brought to other OB/GYN residencies and OB/GYNs in an effort to enhance the symbiotic relationship between medical and dental professionals. PMID- 29184838 TI - Magnifying the Senescence: Impact of Oral Health on Quality of Life and Daily Performance in Geriatrics: A Cross-Sectional Study. AB - Objective: The objective of the study is to study the behavior of the GOHAI as well as the OIDPs as potent measures in oral health related to quality of life in senior citizens. Materials and Methods: An outreach program-based cross-sectional study conducted in Modinagar, Uttar Pradesh, India. A total of 340 study participants aged >60 years were selected from outreach program which were held between January 2017 and April 2017 based on inclusion and exclusion criterion. The dental health status and its influence on the self-perceived value of life was assessed using GOHAI and OIDP index among the participants. The data were estimated using Statistical Package for the Social Sciences version 21.0 (SPSS Inc., Chicago, IL, USA). Chi-square analysis and Pearson correlation were used to test the significance of the independent variables and the distinct the overall oral impact scores in groups with different dental status. Results: OIDP shows that most of the patients are suffering from eating food (57.74) and speaking clearly (45.96). GOHAI shows that most of the geriatric population with a lowest mean score of 2.12 and 2.13 were difficulty in chewing food and sorrowful with the condition of mouth and teeth. Similarly, a lower number of population of 3.68 had difficulty in swallowing food. Conclusion: The prevalence of OIDPs in this geriatric population was high. Oral impact mainly effect their quality or value of life leading to difficulty in eating and verbal communication. PMID- 29184840 TI - Personalized medicine: An era of dosage form development. PMID- 29184839 TI - Correlation of Perceived Self-Rated Oral Health Status with Various Dental Health and Awareness Factors. AB - Aims and Objectives: Self-rated oral health is the key element that has a greater effect on quality of life and found to be authentic and logical to consider this as an indicator for overall oral health status. The aim was to investigate and identify the impact of various social and clinical factors on the perceived self rated oral health status (PSR-OHS). Materials and Methods: A self-administered questionnaire was distributed 600 patients seeking information for age, gender, nationality, educational level, and their last dental visit followed by 15 questions related to social factors (patient self-rated oral health, patient dentist communication, literacy level of the patient, and dental neglect) followed by estimating the clinical oral health status (decayed, missing, and filled teeth [DMFT] scores as per WHO norms). Results: The results were estimated by a single five-point-response-scale question dichotomized into poor and good self-rated oral health. The average mean age for participation in the study is 32.5 years and found to be highly significant (P < 0.01) with inverse relation indicating that younger patients give better PSR-OHS. There were no significant differences in PSR-OHS among other demographic factors. Patients visiting the dentist recently found to be confident about their PSR-OHS and are statistically significant. Pearson correlating scores of social factors and the DMFT scores most concerned in the present study have a significant relation with self-rated oral health status. Conclusions: PSR-OHS is governed by various dental health and awareness factors. It can be used as an important tool by a clinician to assess the clinical examination results which helps to achieve more effective time and patient management. PMID- 29184841 TI - Evaluation of the anesthetic effect of nasal mucosa with tetracaine 0.5% on hemodynamic changes and postoperative pain of septoplasty: A randomized controlled trial. AB - The nasal septum repair surgery is the dangerous operations that any stimulation of this area causes a large change in the rhythm of the heartbeat and blood pressure. This study aimed to determine the effects of tetracaine 0.5% on changes in heartbeat and heart rhythm, hemodynamic changes during surgery, intraoperative bleeding, and pain after septoplasty surgery. The irregular double-blind clinical trial registry of clinical trials Iran with the code number (IRCT: 20150526625N8) in the first half of 2013 on 86 patients in Kashani hospital of Shahrekord. Having selected and matched the patients were divided into two groups. Case group was dropped tetracaine 0.5% in each of the nasal cavity 15 min before the beginning of the operation. The control group was dropped distilled water 15 min preoperation in each of the nasal cavity. The surgery lasted about 30-60 min. Clinical symptoms were evaluated after anesthetic induction as well as pain using the visual analog scale after the operation, in the recovery room. The collected data were analyzed using SPSS version software 17 through independent t-test, Chi square, and repeated measures variance analysis. Postoperative pain intensity in the experimental group compared to the control group was significantly lower than the control group (P < 0.05); however, blood pressure and heart rate during anesthesia, there was no difference between groups (P > 0.05). Based on the findings, intake of tetracaine drop 0.5% has no impact on some hemodynamic changes during septoplasty operation. However, compared with the control group, pain was significantly reduced. PMID- 29184842 TI - The status of Iranian hospital pharmacies according to age-friendly pharmacies criteria. AB - Due to the increasing elderly population and the subsequent increase in their need for medication and more referrals to the pharmacy, this study was conducted to investigate the Iranian hospital pharmacies in terms of age-friendliness criteria. This was a cross-sectional study conducted in 2017. The study population included 3 metropolitan hospital pharmacies selected through clustered sampling, and all their 67 pharmacies were included by census. Data collection tool was a reliable researcher-made checklist (t = 0.85, alpha = 0.9) Data analysis was performed using Kruskal-Wallis test and Mann-Whitney test through SPSS version 24. The results in these three cities showed that only two pharmacies were in a high level of age-friendly. The relationship between type of pharmacy and the final score of age-friendly situation in these cities showed no significant relationship. There was no significant relationship among the average of the final score of the age-friendly situation in three studied cities. Due to the increasing elderly population and the aging society, readiness of Iranian hospital pharmacies to provide services to the elderly will be one of the most challenging issues in the long term. With proper legislation and policies on health-care systems, especially pharmacies, physical and psychological problems in elderly can be reduced in the future. Furthermore, with advancing toward age friendly pharmacies, the community can be empower and become ready encountering elderly problems. PMID- 29184843 TI - The performance implications of pharmacy information system at the university teaching hospitals of Shiraz, Iran: Cluster approach. AB - Pharmacy information system (PIS) is becoming vital in assisting pharmacists to do their responsibilities. The aim of this study was to identify the current PIS implications in teaching hospitals affiliated with Shiraz University of Medical Science. This cross-sectional study was conducted in teaching hospitals affiliated with Shiraz University of Medical Science over the year 2016. Data were collected by observing the PIS as well as interviewing its users based on the researcher-made checklist. The checklist was prepared based on reviewing the Persian and English literature and its content validity was approved by the experts. To determine the reliability of the checklist, inter-rater reliability was used. Data were analyzed using SPSS16, and hospitals were clustered using SK means method. In this study, the least conformity to the standards was shown in smart clinical features (4.54%), pharmaceutical companies' relationship (32.6%), and optimization of drug therapy (34.6%). In contrast, the highest conformity to the standards was shown in reporting capabilities (77.3%) and entry information and input (70.4%). Medication stock checking and optimization of drug therapy were effective features that have made a distinction between hospitals and lead to 95% variance between clusters. Based on the results, the current PIS design pays less attention to clinical features. Besides, clinical information for pharmacists and outside organization relationship were not provided by the current system. Thus, emphasis should be placed on the implementation of corrective actions to eliminate the current system's deficiencies. PMID- 29184844 TI - Effect of different doses of oxytocin on cardiac electrophysiology and arrhythmias induced by ischemia. AB - The onset of acute myocardial ischemia (MI) is accompanied by a rapid increase in electrical instability and often fatal ventricular arrhythmias. This study investigated that whether oxytocin (OT) can modulate ischemia-induced arrhythmias and considered relationships between the severity of arrhythmia and the electrocardiogram parameters during ischemia. OT (0.0001-1 MUg) was administrated intraperitoneally 30 min before ischemia. To examine receptor involved, a selective OT-receptor antagonist, atosiban (ATO), was infused 10 min before OT. OT caused a significant and biphasic dose-dependent reduction in ectopic heart activity and arrhythmia score. OT doses that reduced ventricular arrhythmia elicited significant increase in QT interval. OT attenuated the electrophysiological changes associated with MI and there was significant direct relationship between QRS duration and arrhythmia score. ATO treatment reduced beneficial effects of OT on arrhythmogenesis. Nevertheless, ATO failed to alter OT effects on premature ventricular contractions. We assume that the ability of OT to modulate the electrical activity of the heart may play an important role in the antiarrhythmic actions of OT. PMID- 29184845 TI - The effect of adding ferrous sulfate to methylphenidate on attention deficit/hyperactivity disorder in children. AB - Attention deficit/hyperactivity disorder (ADHD) is one of the most common psychiatric disorders in children with several complications. This study was conducted to investigate the effect of adding ferrous sulfate to methylphenidate in decreasing ADHD symptoms. This study was a double-blind, randomized clinical trial. In this study, 42 nonanemic children with ADHD and serum ferritin below 30 mg/ml were enrolled according to convenience sampling and randomly assigned to two groups of 21 each, cases and controls. The two groups were matched for age and sex. The case group was administered with ferrous sulfate 5 mg/kg in addition to methylphenidate up to 1 mg/kg and the control group with methylphenidate alone. The scores on child symptoms inventory-4 (CSI-4) were recorded at baseline and after 2 months of treatment. Data were analyzed by t-test, Pearson's correlation coefficient, and repeated measures ANOVA in SPSS 16. The scores on CSI-4 decreased significantly at month 2 in both groups (P < 0.001). The scores on attention deficit and hyperactivity subscales of the CSI-4 were significantly lower in the case group than the control group (P < 0.05). The total score on CSI 4 decreased more markedly in the case group (P < 0.04). Use of ferrous sulfate plus methylphenidate can be effective in reducing ADHD symptoms in nonanemic children with low serum ferritin.

This study was conducted to evaluate the cytotoxic activity of ethanolic extract of Acacia catechu bark (ACB) against human squamous cell carcinoma cell line-25 (SCC-25). Cytotoxic effect of ACB extract was determined by 3-(4,5-dimethylthiazol-2-yl) 2,5-diphenyltetrazolium Bromide assay. A. catechu extract was treated SCC-25 cells with 25 and 50 MUg/mL for 24 h. Apoptosis markers such as caspases-8 and 9, bcl-2, bax, and cytochrome c (Cyt-c) were done by RT-PCR. Morphological changes of ACB treated cells were evaluated using acridine orange/ethidium bromide (AO/EB) dual staining. Nuclear morphology and DNA fragmentation were evaluated using propidium iodide (PI) staining. Further, cell cycle analysis was performed using flow cytometry. A. catechu treatment caused cytotoxicity in SCC-25 cells with an IC50 of 52.09 MUg/mL. Apoptotic marker gene expressions were significantly increased on ACB treatment. Staining with AO/EB and PI shows membrane blebbing and nuclear membrane distortion, respectively, and it confirms the apoptosis induction in SCC-25 cells. These results suggest that ACB extract can be used as a modulating agent in oral squamous cell carcinoma. PMID- 29184847 TI - Novel biorelevant dissolution medium as a prognostic tool for polysaccharide based colon-targeted drug delivery system. AB - To overcome the limitations of the conventionally used methods for evaluation of orally administered colon-targeted delivery systems, a novel dissolution method using probiotics has been recently reported. In the present study, universal suitability of this medium composed of five different probiotics is established. Different delivery systems - mini tablets, liquisolid compacts, and microspheres coated with different polysaccharides - were prepared and subjected to sequential dissolution testing in medium with and without microbiota. The results obtained from fluid thioglycollate medium (FTM)-based probiotic medium for all the polysaccharide-based formulations showed statistically similar dissolution profile to that in the rat and goat cecal content media. Hence, it can be concluded that the developed FTM-based probiotic medium, once established, may eliminate the need for further animal sacrifice in the dissolution testing of polysaccharide-based colon-targeted delivery system. PMID- 29184848 TI - One- vs. Three-Fraction Pancreatic Stereotactic Body Radiation Therapy for Pancreatic Carcinoma: Single Institution Retrospective Review. AB - Background/introduction: Early reports of stereotactic body radiation therapy (SBRT) for pancreatic ductal adenocarcinoma (PDAC) used single fraction, but eventually shifted to multifraction regimens. We conducted a single institution review of our patients treated with single- or multifraction SBRT to determine whether any outcome differences existed. Methods and materials: Patients treated with SBRT in any setting for PDAC at our facility were included, from 2004 to 2014. Overall survival (OS), local control (LC), regional control (RC), distant metastasis (DM), and late grade 3 or greater radiation toxicities from the time of SBRT were calculated using Kaplan-Meier estimation to either the date of last follow-up/death or local/regional/distant failure. Results: We identified 289 patients (291 lesions) with pathologically confirmed PDAC. Median age was 69 (range, 33-90) years. Median gross tumor volume was 12.3 (8.6-21.3) cm3 and planning target volume 17.9 (12-27) cm3. Single fraction was used in 90 (30.9%) and multifraction in 201 (69.1%) lesions. At a median follow-up of 17.3 months (IQR 10.1-29.3 months), the median survival for the entire cohort 17.8 months with a 2-year OS of 35.3%. Univariate analysis showed multifraction schemes to have a higher 2-year OS 30.5% vs. 37.5% (p = 0.019), it did not hold significance on MVA. Multifractionation schemes were found to have a higher LC on MVA (HR = 0.53, 95% CI, 0.33-0.85, p = 0.009). At 2 years, late grade 3+ toxicity was 2.5%. Post-SBRT CA19-9 was found on MVA to be a prognostic factor for OS (HR = 1.01, 95% CI, 1.01-1.01, p = 0.009), RC (HR = 1.01, 95% CI 1.01-1.01, p = 0.02), and DM (HR = 1.01, 95% CI, 1.01-1.01, p = 0.001). Conclusion: Our single institution retrospective review is the largest to date comparing single and multifraction SBRT and the first to show multifraction regimen SBRT to have a higher LC than single fractionation. Additionally, we show low rates of severe late toxicity with SBRT. PMID- 29184849 TI - Giving Drugs a Second Chance: Overcoming Regulatory and Financial Hurdles in Repurposing Approved Drugs As Cancer Therapeutics. AB - The repositioning or "repurposing" of existing therapies for alternative disease indications is an attractive approach that can save significant investments of time and money during drug development. For cancer indications, the primary goal of repurposed therapies is on efficacy, with less restriction on safety due to the immediate need to treat this patient population. This report provides a high level overview of how drug developers pursuing repurposed assets have previously navigated funding efforts, regulatory affairs, and intellectual property laws to commercialize these "new" medicines in oncology. This article provides insight into funding programs (e.g., government grants and philanthropic organizations) that academic and corporate initiatives can leverage to repurpose drugs for cancer. In addition, we highlight previous examples where secondary uses of existing, Food and Drug Administration- or European Medicines Agency-approved therapies have been predicted in silico and successfully validated in vitro and/or in vivo (i.e., animal models and human clinical trials) for certain oncology indications. Finally, we describe the strategies that the pharmaceutical industry has previously employed to navigate regulatory considerations and successfully commercialize their drug products. These factors must be carefully considered when repurposing existing drugs for cancer to best benefit patients and drug developers alike. PMID- 29184850 TI - Internalization of the Active Subunit of the Aggregatibacter actinomycetemcomitans Cytolethal Distending Toxin Is Dependent upon Cellugyrin (Synaptogyrin 2), a Host Cell Non-Neuronal Paralog of the Synaptic Vesicle Protein, Synaptogyrin 1. AB - The Aggregatibacter actinomycetemcomitans cytolethal distending toxin (Cdt) is a heterotrimeric AB2 toxin capable of inducing lymphocytes, and other cell types, to undergo cell cycle arrest and apoptosis. Exposure to Cdt results in binding to the cell surface followed by internalization and translocation of the active subunit, CdtB, to intracellular compartments. These events are dependent upon toxin binding to cholesterol in the context of lipid rich membrane microdomains often referred to as lipid rafts. We now demonstrate that, in addition to binding to the plasma membrane of lymphocytes, another early and critical event initiated by Cdt is the translocation of the host cell protein, cellugyrin (synaptogyrin-2) to the same cholesterol-rich microdomains. Furthermore, we demonstrate that cellugyrin is an intracellular binding partner for CdtB as demonstrated by immunoprecipitation. Using CRISPR/cas9 gene editing we established a Jurkat cell line deficient in cellugyrin expression (JurkatCg-); these cells were capable of binding Cdt, but unable to internalize CdtB. Furthermore, JurkatCg- cells were not susceptible to Cdt-induced toxicity; these cells failed to exhibit blockade of the PI-3K signaling pathway, cell cycle arrest or cell death. We propose that cellugyrin plays a critical role in the internalization and translocation of CdtB to critical intracellular target sites. These studies provide critical new insight into the mechanism by which Cdt, and in particular, CdtB is able to induce toxicity. PMID- 29184851 TI - Bid-Induced Release of AIF/EndoG from Mitochondria Causes Apoptosis of Macrophages during Infection with Leptospira interrogans. AB - Leptospirosis is a global zoonotic infectious disease caused by pathogenic Leptospira species. Leptospire-induced macrophage apoptosis through the Fas/FasL caspase-8/3 pathway plays an important role in the survival and proliferation of the pathogen in hosts. Although, the release of mitochondrial apoptosis-inducing factor (AIF) and endonuclease G (EndoG) in leptospire-infected macrophages has been described, the mechanisms linking caspase and mitochondrion-related host cell apoptosis has not been determined. Here, we demonstrated that leptospire infection induced apoptosis through mitochondrial damages in macrophages. Apoptosis was caused by the mitochondrial release and nuclear translocation of AIF and/or EndoG, leading to nuclear DNA fragmentation. However, the mitochondrion-related CytC-caspase-9/3 pathway was not activated. Next, we found that the release and translocation of AIF and/or EndoG was preceded by the activation of the BH3-interacting domain death agonist (Bid). Furthermore, our data demonstrated that caspase-8 was activated during the infection and caused the activation of Bid. Meanwhile, high reactive oxygen species (ROS) trigged by the infection caused the dephosphorylation of Akt, which also activated Bid. In conclusion, Bid-mediated mitochondrial release of AIF and/or EndoG followed by nuclear translocation is a major mechanism of leptospire- induced apoptosis in macrophages, and this process is modulated by both caspase-8 and ROS-Akt signal pathways. PMID- 29184852 TI - A New Determinant of Candida glabrata Virulence: The Acetate Exporter CgDtr1. AB - Persistence and virulence of Candida glabrata infections are multifactorial phenomena, whose understanding is crucial to design more suitable therapeutic strategies. In this study, the putative multidrug transporter CgDtr1, encoded by ORF CAGL0M06281g, is identified as a determinant of C. glabrata virulence in the infection model Galleria mellonella. CgDTR1 deletion is shown to decrease the ability to kill G. mellonella larvae by decreasing C. glabrata ability to proliferate in G. mellonella hemolymph, and to tolerate the action of hemocytes. The possible role of CgDtr1 in the resistance to several stress factors that underlie death induced by phagocytosis was assessed. CgDTR1 was found to confer resistance to oxidative and acetic acid stress. Consistently, CgDtr1 was found to be a plasma membrane acetic acid exporter, relieving the stress induced upon C. glabrata cells within hemocytes, and thus enabling increased proliferation and virulence against G. mellonella larvae. PMID- 29184853 TI - Porphyromonas gingivalis-Derived Lipopolysaccharide Combines Hypoxia to Induce Caspase-1 Activation in Periodontitis. AB - Periodontitis is defined as inflammation affecting the supporting tissue of teeth. Periodontal pathogens initiate the disease and induce inflammatory host response. Hypoxia may accelerate the process by producing pro-inflammatory factors. The aim of this study is to investigate the effect of Porphyromonas gingivalis (P. gingivalis) lipopolysaccharides (LPS) and Escherichia coli (E. coli) LPS in inducing caspase-1 activation in normoxic or hypoxic phases. The results showed that healthy gingiva was in a normoxic phase (HIF-1alpha negative). However, hypoxia appeared in periodontitis, in which NLRP3, cleaved caspase-1, interleukin 1 beta (IL-1beta) and caspase-1-induced cell death was enhanced in periodontitis specimens. The in vitro experiment showed that P. gingivalis LPS slightly decreased the level of NLRP3 and IL-1beta in gingival fibroblasts under normoxia. Surprisingly, hypoxia reversed the effects of P. gingivalis LPS, highly promoted caspase-1 activation and IL-1beta maturation. E. coli LPS, a kind of pathogen-associated molecular pattern (PAMP) was chosen to simulate the effect of Gram-negative microbiota. Different from P. gingivalis LPS, E. coli LPS enhanced IL-1beta maturation both in normoxia and hypoxia. Moreover, E. coli LPS turned normoxia into hypoxia phase in experimental periodontitis model, which may subsequently propel the inflammatory effect of P. gingivalis LPS. It was concluded that E. coli LPS induced a hypoxic phase, which is a combing pathological factor of P. gingivalis LPS in caspase-1 activating and IL-1beta maturation in periodontal inflammation. PMID- 29184855 TI - Dealing with complex overactive bladder syndrome patient profiles with focus on fesoterodine: in or out of the EAU guidelines? AB - Overactive bladder (OAB) syndrome is a common, complex, and challenging condition. To assist the management of these patients, the European Association of Urology (EAU) updates its guidelines annually. This review reports the presentations from the symposium titled "Dealing with complex OAB patient profiles: in or out of the EAU guidelines?" held at the 32nd EAU Annual Congress in March 2017 in London. The symposium focused on three groups of OAB patients: women who may also suffer pelvic organ prolapse, stress urinary incontinence, the genitourinary syndrome of menopause (GSM); patients at risk of cognitive impairment; and elderly patients. The aim of the symposium was to determine how the 2017 EAU guidelines can best assist physicians, as well as to assess the benefits of fesoterodine in these patients. The EAU guidelines recommend antimuscarinic agents (grade A) for the medical treatment of OAB. In women, OAB is correlated with GSM, both of which are underdiagnosed and undertreated. Fesoterodine decreases OAB symptoms and the associated limitation of physical activity. A combination of fesoterodine and vaginal estrogens is appropriate for OAB associated with GSM. In patients at risk of cognitive impairment, prescribers should pay particular attention to the choice of medication. Fesoterodine is a Pgp substrate with limited ability to cross the blood-brain barrier, which may explain the lack of negative effects on the central nervous system observed in clinical trials of this agent. OAB should not be regarded as a normal consequence of aging. Fesoterodine has been extensively investigated in the elderly, and is the only anticholinergic drug licensed for OAB in this population, rated B (beneficial) according to the Fit for the Aged classification for lower-urinary tract symptoms. The EAU guidelines are a valuable resource for physicians managing patients with OAB, and the pharmacological properties of fesoterodine offer credible clinical advantages in these three patient groups. PMID- 29184854 TI - Oncolytic virus delivery: from nano-pharmacodynamics to enhanced oncolytic effect. AB - With the advancement of a growing number of oncolytic viruses (OVs) to clinical development, drug delivery is becoming an important barrier to overcome for optimal therapeutic benefits. Host immunity, tumor microenvironment and abnormal vascularity contribute to inefficient vector delivery. A number of novel approaches for enhanced OV delivery are under evaluation, including use of nanoparticles, immunomodulatory agents and complex viral-particle ligands along with manipulations of the tumor microenvironment. This field of OV delivery has quickly evolved to bioengineering of complex nanoparticles that could be deposited within the tumor using minimal invasive image-guided delivery. Some of the strategies include ultrasound (US)-mediated cavitation-enhanced extravasation, magnetic viral complexes delivery, image-guided infusions with focused US and targeting photodynamic virotherapy. In addition, strategies that modulate tumor microenvironment to decrease extracellular matrix deposition and increase viral propagation are being used to improve tumor penetration by OVs. Some involve modification of the viral genome to enhance their tumoral penetration potential. Here, we highlight the barriers to oncolytic viral delivery, and discuss the challenges to improving it and the perspectives of establishing new modes of active delivery to achieve enhanced oncolytic effects. PMID- 29184856 TI - Optimal therapy for patients with hepatocellular carcinoma and resistance or intolerance to sorafenib: challenges and solutions. AB - The only US Food and Drug Administration (FDA)-approved first-line systemic therapy for hepatocellular carcinoma (HCC) is sorafenib; however, resistance or intolerance to sorafenib is unfortunately common. In this review, we briefly describe systemic therapies that can be considered for patients with HCC who show resistance or intolerance to sorafenib. For all patients with HCC who need systemic therapy, we strongly advocate for participation in clinical trials. Cytotoxic chemotherapy plays a minor role in the treatment of advanced HCC, with some data supporting the use of FOLFOX (infusional fluorouracil, leucovorin, and oxaliplatin) and GEMOX (gemcitabine-oxaliplatin). Multi-target kinase inhibitors such as lenvantinib and regorafenib have recently met their primary endpoints as first- and second-line therapy, respectively, with regorafenib now representing the only FDA-approved drug for second-line treatment of HCC. Other targeted therapies remain under investigation, but results so far have not significantly changed clinical practice. Immunotherapy is an interesting area of research in the treatment of HCC with preclinical and early clinical data demonstrating exciting results; thus numerous investigational studies are currently focusing on immunotherapy in the treatment of HCC. While systemic treatment options in HCC remain a challenge for providers, in this review, we summarize the current literature and highlight areas of progress with respect to the treatment of patients with HCC and resistance or intolerance to sorafenib. PMID- 29184857 TI - Vacuum extraction vaginal delivery: current trend and safety. AB - Operative vaginal birth retains an important role in current obstetric practice. However, there is an increasing trend in the rate of cesarean section in Korea. Surgical delivery is more advantageous than cesarean section, but the rate of operative vaginal delivery is decreasing for various reasons. Furthermore, there is no unified technique for vacuum extraction delivery. In this context, this review was performed to provide details of the necessary conditions, techniques, benefits, and risks of operative vaginal delivery. Future research should focus on overcoming the limitations of operative vaginal delivery. PMID- 29184858 TI - What is fetal programming?: a lifetime health is under the control of in utero health. AB - The "Barker hypothesis" postulates that a number of organ structures and associated functions undergo programming during embryonic and fetal life, which determines the set point of physiological and metabolic responses that carry into adulthood. Hence, any stimulus or insult at a critical period of embryonic and fetal development can result in developmental adaptations that produce permanent structural, physiological and metabolic changes, thereby predisposing an individual to cardiovascular, metabolic and endocrine disease in adult life. This article will provide evidence linking these diseases to fetal undernutrition and an overview of previous studies in this area as well as current advances in understanding the mechanism and the role of the placenta in fetal programming. PMID- 29184859 TI - Risk factors for massive postpartum bleeding in pregnancies in which incomplete placenta previa are located on the posterior uterine wall. AB - Objective: To identify factors associated with massive postpartum bleeding in pregnancies complicated by incomplete placenta previa located on the posterior uterine wall. Methods: A retrospective case-control study was performed. We identified 210 healthy singleton pregnancies with incomplete placenta previa located on the posterior uterine wall, who underwent elective or emergency cesarean section after 24 weeks of gestation between January 2006 and April 2016. The cases with intraoperative blood loss (>=2,000 mL) or transfusion of packed red blood cells (>=4) or uterine artery embolization or hysterectomy were defined as massive bleeding. Results: Twenty-three women experienced postpartum profuse bleeding (11.0%). After multivariable analysis, 4 variables were associated with massive postpartum hemorrhage (PPH): experience of 2 or more prior uterine curettage (adjusted odds ratio [aOR], 4.47; 95% confidence interval [CI], 1.29 to 15.48; P=0.018), short cervical length before delivery (<2.0 cm) (aOR, 7.13; 95% CI, 1.01 to 50.25; P=0.049), fetal non-cephalic presentation (aOR, 12.48; 95% CI, 1.29 to 121.24; P=0.030), and uteroplacental hypervascularity (aOR, 6.23; 95% CI, 2.30 to 8.83; P=0.001). Conclusion: This is the first study of cases with incomplete placenta previa located on the posterior uterine wall, which were complicated by massive PPH. Our findings might be helpful to guide obstetric management and provide useful information for prediction of massive PPH in pregnancies with incomplete placenta previa located on the posterior uterine wall. PMID- 29184860 TI - Safety of umbilical cord milking in very preterm neonates: a randomized controlled study. AB - Objective: To investigate the safety of umbilical cord milking on both the mother and neonate among very preterm deliveries of less than 33 weeks of gestation. Methods: Pregnant women who were expected to deliver at between 24 0/7 and 32 6/7 weeks of gestation were randomized to either the umbilical cord milking or immediate cord clamping group. Maternal and neonatal data associated with delivery, in addition to neonatal morbidity and mortality data, were collected and analyzed. Results: Of the 66 preterm deliveries included in the study, 34 were randomized into the milking and 32 into the clamping group. Differences between maternal pre- and post-partum hemoglobin levels were 1.35 g/dL in the milking and 1.58 g/dL in the clamping group (P=0.451). Neonatal Apgar scores at both 1 and 5 minutes, initial blood gas analysis results, body temperature at admission, need for early intubation, and maximum bilirubin levels were all similar between the 2 groups. However, neonatal hemoglobin levels at birth (15.79 vs. 14.69 g/dL; P<0.05) and at 24 hours of age (14.83 vs. 13.29 g/dL; P<0.05) were significantly higher in the milking group. Neonates in the clamping group required more blood transfusion (1.78 vs. 0.93; P=0.049), and a higher percentage of neonates in the clamping group required inotropic drugs (63% vs. 29%; P=0.007). The mortality rate was significantly lower in the milking group (6% vs. 28%; P=0.015). Conclusion: Umbilical cord milking can be a safe and beneficial procedure for both the mother and the neonate in deliveries of less than 33 weeks of gestation. PMID- 29184861 TI - Efficacy and safety of venous thromboembolism prophylaxis with fondaparinux in women at risk after cesarean section. AB - Objectives: Cesarean section is associated with an increased risk for venous thromboembolism (VTE). The safety and efficacy of primary prophylaxis of fondaparinux, a synthetic sulfated pentasaccharide heparin analog, in women at risk after cesarean section is uncertain. Methods: This was a retrospective study of 295 cases of pregnant women presenting to a tertiary referral center of Nara, Japan, to evaluate the usefulness of thromboprophylaxis with fondaparinux after cesarean delivery between 2011 and 2012. Patients were initially received unfractionated heparin (once 5,000 IU subcutaneously, twice a day), starting 6 hours after cesarean section for 24 hours, and then treated with fondaparinux (once 2.5 mg daily, subcutaneously) for 5 days. The primary efficacy end-point was an improvement in the incidence of symptomatic VTE or fatal post-cesarean pulmonary thromboembolism. The primary safety end-point was major bleeding during treatment. Results: There were neither any episodes of symptomatic VTE cases nor maternal deaths. A total of 10 patients had a bleeding event. Major bleeding complication was observed in 2 (0.68%) of 295 patients receiving fondaparinux. Non-major bleeding into critical sites was observed in 8 patients, often at surgical sites, and recovery was not delayed. Conclusion: This study demonstrates the safety and efficacy of fondaparinux in women at high risk of VTE after cesarean section. Large phase trials comparing clinical outcomes with fondaparinux across a wide spectrum of patients are needed to confirm these observations. PMID- 29184863 TI - A retrospective comparison of outcome in IB2 and IIA cervical cancer patients treated with primary concurrent chemoradiation versus radical hysterectomy with or without tailored adjuvant therapy. AB - Objective: The aim of our study is to compare the overall survival (OS), progression-free survival (PFS), and treatment-related morbidities between primary concurrent chemoradiation therapy (CCRT) vs. radical hysterectomy (RH) with or without tailored adjuvant therapy in patients with stages IB2 and IIA cervical cancer. Methods: This was a retrospective study of 113 patients with IB2 or IIA cervical cancer treated with either primary CCRT (n=49) or RH (n=64) with or without tailored adjuvant therapy between 2002 and 2011 at Keimyung University Dongsan Medical Center. Patients in RH group was divided into those undergoing surgery alone (n=26) and those undergoing surgery with adjuvant therapy (n=38). Results: The median follow up period was 66 months. The 5-year OS by treatment modality was 88.7% for the 64 patients in the RH group and 72.8% for 49 patients in the CCRT group (P=0.044). The 5-year PFS was 82.3% and 65.6% after RH group and CCRT group (P=0.048), respectively. Grade 3-4 complication was less frequent after RH alone (7.7%) than RH with adjuvant therapy (34.2%) or CCRT group (28.6%) (P=0.047). Conclusion: The RH group seems to be superior to the CCRT group in oncologic outcomes. However, considering the selection bias including tumor size, lymph node meta, and parametrial invasion in pretreatment magnetic resonance imaging, both treatment modalities are reasonable and feasible in cervical cancer IB2 and IIA. It is important to choose the appropriate treatment modality considering the age and general condition of the patient. Randomized controlled study is needed to confirm the result of our study and determine the optimal treatment. PMID- 29184862 TI - The clinical significance of D-dimer concentrations in patients with gestational hypertensive disorders according to the severity. AB - Objective: Pregnancy is a major risk factor of thromboembolism, and the patients with preeclampsia (PE) are known to have higher risk of thromboembolic complications than normal pregnant women. D-dimer is a well-established laboratory marker for the screening of venous thromboembolism (VTE), but the concentrations of d-dimer tend to increase physiologically in pregnant women throughout the gestational age. We performed this study to evaluate the clinical significance of d-dimer concentrations in patients with gestational hypertensive disorders (GHD) according to the severity. Methods: Retrospective cohort study was performed in one institution. Singleton pregnant women with GHD were enrolled, and their antepartum concentrations of d-dimer were measured as a part of routine evaluation for patients suspected with PE. Patients with multiple gestations, rheumatic diseases, autoimmune diseases, or suspected VTE were excluded. A categorization of severity about PE was based on the general criteria. Results: In 73.3% of study population, their d-dimer concentrations exceeded the normal range (>0.55 mg/L). A significantly greater proportion of pregnant women had excessive concentrations of d-dimer in the severe GHD than in the non-severe GHD (89.8% vs. 53.7%; P<0.01). Patients with severe GHD had significantly higher median concentrations of d-dimer than those with non-severe GHD (median [range], 2.00 mg/L [0.11 to 7.49] vs. 0.71 mg/L [0.09 to 5.39]; P<0.01) although their earlier gestational ages of sampling. Conclusion: Maternal concentrations of d-dimer were significantly elevated in patients with severe features than those without severe features among those with GHD. Some pregnant women with GHD can have markedly elevated concentrations of d-dimer without any evidence of current VTE. PMID- 29184864 TI - Prognostic value of preoperative lymphocyte-monocyte ratio in elderly patients with advanced epithelial ovarian cancer. AB - Objective: To investigate the prognostic significance of preoperative lymphocyte monocyte ratio (LMR) in elderly patients with advanced epithelial ovarian cancer (EOC) receiving primary cytoreductive surgery and adjuvant platinum-based chemotherapy. Methods: A total of 42 elderly patients (>=65 years) diagnosed with EOC who are receiving primary cytoreductive surgery and adjuvant platinum-based chemotherapy from 2009 to 2012 was included. LMR was calculated from complete blood cell count sampled before operation. Receiver operating characteristic (ROC) curves were used to calculate optimal cut-off values for LMR. Prognostic significance with respect to overall survival (OS) and progression-free survival (PFS) were determined using log-rank test and Cox regression analysis. Results: The optimized LMR cut-off value determined by ROC curve analysis was 3.63 for PFS and OS. The high LMR group (LMR >=3.63) was found to be significantly more associated with optimal debulking (P=0.045) and platinum response (P=0.018) than the low LMR group. In addition, Kaplan-Meier analysis revealed the LMR-high group was significantly more associated with high PFS and OS rates (P=0.023 and P=0.033, respectively), and univariate analysis revealed that a high LMR, histology type, and optimal debulking and platinum responses were significantly associated with prolonged PFS and OS. However, subsequent Cox multivariate analysis showed only optimal debulking and platinum response were independent prognostic factors of PFS or OS. Conclusion: This study suggests that LMR might be associated with treatment and survival outcomes in elderly patients with EOC receiving standard oncology treatment. PMID- 29184865 TI - Etiological evaluation of repeated biochemical pregnancy in infertile couples who have undergone in vitro fertilization. AB - Objective: This study aims to investigate whether there are any notable etiologies for repeated biochemical pregnancy (RBP) and, if so, to compare those etiologies associated with repeated spontaneous abortion in infertile couples who have undergone in vitro fertilization (IVF). Methods: Forty-four infertile couples who underwent IVF and experienced RBP were included in this study. RBP was defined as more than 2 early pregnancy losses that occurred before the detection of a gestational sac, with ectopic pregnancies specifically excluded by serial serum beta human chorionic gonadotropin evaluation. Forty-three infertile couples who underwent IVF and experienced recurrent spontaneous abortion (RSA) were included as a control group. Karyotype analysis, anatomic evaluation of uterus, endocrine and immunological evaluation were performed. In addition, the number of pregnant women confirmed by 12 weeks' gestation was compared between groups. Results: Immunological factors (RSA: 20.9% vs. RBP: 29.5%, P=0.361), diminished ovarian reserve (RSA: 10.9% vs. RBP: 17%, P=0.552), and parental chromosomal abnormalities (RSA: 18.6% vs. RBP: 9.1%, P=0.218) were not different between groups. Additionally, the incidence of uterine factors (RSA: 11.6% vs. RBP: 4.6%, P=0.206), unknown cause (RSA: 48.8% vs. RBP: 54.5%, P=0.161), and the pregnancy outcome identified until 12 weeks' gestation (RSA: 46.5% vs. RBP: 38.6%, P=0.520) did not differ between groups. Conclusion: In the present study, the causes of RBP after IVF were similar to those of RSA. Accordingly, we suggest that efforts should be made to define the etiology of RBP, particularly for infertile couples, and that possible management strategies should be offered. PMID- 29184866 TI - Therapeutic outcomes of methotrexate injection in unruptured interstitial pregnancy. AB - Objective: To examine the therapeutic outcomes of methotrexate (MTX) in the treatment of unruptured interstitial pregnancy. Methods: We reviewed the medical records of patients who were diagnosed with interstitial pregnancy and received MTX as first-line treatment between January 2003 and July 2014 at CHA Gangnam Medical Center. The treatment success rates and subsequent pregnancy outcomes were examined. Results: Ninety-seven patients were diagnosed with interstitial pregnancy between January 2003 and July 2014. Of them, 38 initially received MTX treatment. The diagnosis was made at a median of 6+3 weeks (5+0 to 11+3 weeks). Thirty patients received a systemic MTX injection, while the other 8 received a local MTX injection. Systemic treatment composed of an 8-day alternating MTX regimen, single-dose regimen, or high-dose regimen (100 mg/m2 + 200 mg/m2 intravenously over 12 hours). The local injection consisted of a direct MTX injection into the gestational sac with or without systemic MTX injection. Twenty one patients (55.3%) were successfully treated with MTX. However, MTX therapy failed in 17 patients (44.7%), who required surgery. Mode of MTX treatment was the only predictive variable of MTX treatment success (P=0.039). Treatment success was seen in 7 of 8 patients (87.5%) in the local MTX group vs. 14 of 30 patients (46.7%) in the systemic MTX group. After treatment, 13 patients attempted a successive pregnancy; of them, 10 patients had a confirmed clinical pregnancy and healthy live birth. Conclusion: Combined MTX treatment including a local injection might be an initial approach to the treatment of interstitial pregnancy. PMID- 29184867 TI - Comorbidity of gynecological and non-gynecological diseases with adenomyosis and endometriosis. AB - Objective: Adenomyosis and endometriosis are relatively common gynecological diseases that exhibit many common features. This study identified gynecological and non-gynecological diseases that exhibited comorbidity with adenomyosis and endometriosis in Korean women. Methods: We used Health Insurance Review and Assessment data from 2009 to 2011 and searched for adenomyosis and endometriosis (coded as N80.1 and D25 in International Classification of Disease, 10th revision [ICD-10], respectively). We selected records from patients who had independent disease occurrences in each year, and comorbidities were estimated using Fisher's exact test. We computed each year's similarities and combined 3 years' results using Fisher's P-value summation method. Results: A total of 61,516 patients' data were collected during the study period. The prevalence of adenomyosis and endometriosis were similar each year: 12.4% and 9.3% in 2009, 12.5% and 9.4% in 2010 and 13.3% and 9.1% in 2011, respectively. Meta-analysis revealed that 31 ICD 10 codes were significantly related with adenomyosis, and 44 ICD-10 codes were related with endometriosis. Gynecological diseases, such as leiomyoma and benign ovarian tumor, were significantly related to adenomyosis and endometriosis. Non gynecological diseases, such as anemia and hypercholesterolemia, were also related to adenomyosis and endometriosis. Conclusion: We must monitor for the presence of gynecological and non-gynecological diseases with co-morbidities during evaluations and follow-up of patients with adenomyosis or endometriosis. PMID- 29184868 TI - Long-term recurrence-free survival of a patient with advanced pure primary ovarian squamous cell carcinoma treated with dose-dense paclitaxel combined with carboplatin. AB - We describe an extremely rare case of advanced pure primary ovarian squamous cell carcinoma (SCC), treated by adjuvant chemotherapy with dose-dense paclitaxel combined with carboplatin (dd-TC) plus the combination chemotherapy with irinotecan and cisplatin (CPT-P), with long-term recurrence-free survival. A 71 year-old woman complaining of lower abdominal pain was referred to our hospital and a 7-cm-diameter solid tumor was identified. She was diagnosed with a left ovarian tumor that was highly suspicious for malignancy based on ultrasonography, magnetic resonance imaging, and contrast-enhanced computed tomography. Bilateral salpingo-oophorectomy, low-anterior colon resection, and colostomy were performed. Intra- and post-operative histopathological diagnosis revealed International Federation of Gynecology and Obstetrics stage IIIc well differentiated pure ovarian SCC. As adjuvant chemotherapy, 2 courses of dd-TC were administered, followed by 3 courses of CPT-P; the patient then underwent 4 additional courses of dd-TC. Both regimens were effective and there has been no recurrence or metastasis thus far in the 5 years since the operation. PMID- 29184869 TI - Skin metastases in ovarian clear cell adenocarcinoma: a case report and a review of the literature. AB - Epithelial ovarian carcinoma is a high mortality neoplasm in gynecologic malignancy. It usually can metastasize to distant organs such as pleura, liver, lung, and lymph nodes. However, the skin metastases are not common and related to very poor prognosis. Here we report a 54-year-old patient with ovarian clear cell carcinoma with skin metastases on the anterior chest at 11 months after initial diagnosis. Although she received palliative chemotherapy, she expired due to disease progression 2 months later after the diagnosis of skin metastases. PMID- 29184870 TI - A retroperitoneal dedifferentiated liposarcoma mimicking an ovarian tumor. AB - A 74-year-old postmenopausal woman visited our gynecology clinic complaining of a palpable abdominal mass. Physical and radiological evaluation indicated that the mass exhibited features of a left ovarian neoplasm showing heterogeneous enhancement. Surgical resection was performed to confirm this suspicion. During surgery, a mass was observed only in the left ovary with no invasive growth, but adhesions to the surrounding peritoneum were seen. Given the patient's age, large mass size, and accompanying uterine myoma and right ovarian cyst, total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. The final pathologic diagnosis was dedifferentiated liposarcoma. The liposarcoma was suspected to originate from retroperitoneal adipose tissue rather than the ovary. Radiotherapy was planned if a gross lesion indicating recurrence followed 6 months later. This case required a considerable multi-disciplinary approach for diagnosis and treatment because of its ambiguous clinical and radiological findings. PMID- 29184871 TI - Peptide YY producing strumal carcinoid tumor of the ovary in a postmenopausal woman: a rare cause of chronic constipation. AB - Strumal carcinoid tumor of the ovary is a rare subtype of ovarian carcinoid tumors; it is characterized by an intimate mixture of thyroid and carcinoid tissues. We present a case of a 64-year-old woman who presented with the chief complaint of persistent, severe constipation for over 5 years; she was later found to have an ovarian strumal carcinoid tumor. Computed tomography showed a well-defined solid mass measuring 6.4 cm at the right adnexa. The patient underwent right salpingo-oophorectomy and was histopathologically diagnosed as having a strumal carcinoid tumor. Immunohistochemical examination showed immunoreactivity for peptide YY (PYY), which exerts an inhibitory effect on the peristaltic actions of the distal intestine. After surgery, the patient's constipation resolved rapidly, suggesting a correlation between PYY producing ovarian carcinoid tumor and constipation. This is the first case report of PYY producing primary strumal carcinoid tumor of the ovary associated with persistent, severe constipation from Korea. PMID- 29184873 TI - Two cases of hymenal scars occurred by child rape. AB - Children who have been raped some years back may have hymenal scars. However, medical professionals are not accustomed in assessing these scars because of the lack of experience in performing physical examinations of the external genitalia of children who suffered from rape some years back. Moreover, the importance of physical examination of the victim's external genitalia is sometimes overlooked. Two cases of rape victims with hymenal scars who visited Daegu Child Sexual Abuse Response Center several years after their first sexual abuse along with a literature review are presented here. PMID- 29184872 TI - Laparoscopic total extraperitoneal hernia repair of fallopian tube indirect inguinal hernia in reproductive aged woman: a case report. AB - An indirect inguinal hernia containing the fallopian tube alone is extremely rare in reproductive-aged women without any genital tract anomalies. Despite this rarity, early diagnosis and adequate management is important to prevent strangulation and recurrence. We present a case of an indirect inguinal hernia containing only the fallopian tube in the hernia sac, which was successfully reduced by using a laparoscopic total extraperitoneal approach and repaired with a polypropylene mesh. PMID- 29184874 TI - Persistent low-level elevation of serum human chorionic gonadotropin after termination of pregnancy: a rare case of peritoneal trophoblastic implant. AB - Peritoneal trophoblastic implant can occur after treatment of ectopic pregnancy. Similarly, after termination of intrauterine pregnancy, trophoblastic implants are rare but can be a complication of perforation during dilatation and curettage. We report an extremely rare case of trophoblastic implant on the myometrium, ovarian surface, and peritoneal wall 4 months after uncomplicated dilatation and curettage. To the best of our knowledge, this is the first case of peritoneal trophoblastic implant following dilatation and curettage without uterine perforation. Knowledge of this case is useful for the management of patients with persistent low-level elevation of serum human chorionic gonadotropin after termination of pregnancy. PMID- 29184875 TI - Assessing cosmetic results after conventional thyroidectomy using the EASY-EYE_C: a double-blind randomized controlled trial. AB - Purpose: The incidence of thyroid cancer is relatively high, especially in young women, and postoperative scarring after thyroidectomy is an important problem for both patients and clinicians. Currently, there is no available product that can be used for wound protection during thyroid surgery. We used the EASY-EYE_C, a new silicone-based wound protector. Methods: We conducted a double-blind randomized controlled trial to assess the efficacy of the EASY-EYE_C with surgical scars. We studied 66 patients who underwent conventional total thyroidectomy or hemithyroidectomy performed by a single surgeon from August 2015 to June 2016. At 6-week follow-up, a single blinded physician observed the wounds to make clinical assessments using the Patient and Observer Scar Assessment Scale (POSAS), the Vancouver Scar Scale (VSS), and a modified Stony Brook Scar Evaluation Scale (SBSES). Results: There were no significant differences by sex, age, type of surgery, body mass index, length of wound, incision site (from sternal notch), or thyroid weight, but the duration of operation was significantly shorter in the experimental group (E group). The e-group also had better POSAS scores than the control group (C group), with means of 43.2 (standard deviation [SD], +/-15.9) versus 68.3 (SD, +/-21.5), respectively (P < 0.05). The modified SBSES and VSS scores were similar to those from the POSAS. Conclusion: In this study, all scores for evaluating outcomes were higher in the E group than in the C group. In addition, the operation time was significantly shorter in the E group. Therefore, the EASY-EYE_C may be useful for improving the cosmetic outcomes of conventional thyroid surgery. PMID- 29184876 TI - Feasibility of sentinel lymph node dissection using Tc-99m phytate in papillary thyroid carcinoma. AB - Purpose: Various methods of sentinel lymph node (SLN) biopsy in thyroid cancer have been introduced. Tc-99m phytate as a radiotracer has been successfully utilized for SLN biopsy in breast, cervix, and endometrial cancer. We assessed the feasibility of SLN dissection using Tc-99m phytate in papillary thyroid carcinoma (PTC). Methods: Seventeen patients with PTC were prospectively enrolled. Ultrasound-guided peritumoral injection of 55.5 MBq Tc-99m phytate in 0.25-mL normal saline was performed. Preoperative single-photon emission-computed tomography (SPECT) and intraoperative gamma-probe were used for SLN detection during operation. Results: Identification rate of SLNs was 70.6% (12 of 17) with SPECT, and 88.2% (15 of 17) with gamma-probe. Combined SPECT and gamma-probe had identification rates of 88.2% (15 of 17). Identification rates of SLNs in central LN compartments were 82.4% (14 of 17) and 41.2% (7 of 17) in lateral LN compartments. Overall sensitivity, specificity, positive predictive value, and negative predictive value of the results of SLN biopsy were 91.6%, 100%, 88.4%, and 100%, respectively. Eight patients (47.1%) had metastasis in SLNs; all patients had SLN metastasis in the central compartment and 2 patients had SLN metastasis in both the central and lateral compartments. Conclusion: Combined SPECT and gamma-probe could detect SLNs with an 88.2% identification rate in PTC. SLN biopsy using Tc-99m phytate is technically feasible. Further investigation is warranted for clinical application of Tc-99m phytate in PTC. PMID- 29184877 TI - Effect of end-to-side inverted mattress pancreaticojejunostomy following central pancreatectomy on the prevention of pancreatic fistula. AB - Purpose: Central pancreatectomy (CP) may be indicated for the treatment of benign or low-grade malignant tumor in the neck and proximal body of the pancreas. Pancreatic fistula is one of the most common complications after CP. In this study, we suggested an inverted mattress pancreaticojejunostomy (IM-PJ) technique to decrease the risk of pancreatic fistula. Methods: Between 2010 and 2015, CP was performed with IM-PJ for 10 consecutive patients with a benign or low-grade malignant tumor in the neck and proximal body of the pancreas. All clinical and pathological data were analyzed retrospectively. Results: Median age was 56.4 years (range, 17-75 years). Median surgery duration was 286 minutes (range, 205 410 minutes). In all cases, the distal stump was reconstructed using the IM-PJ method. Median duration of hospital stay was 23.8 days (range, 9-53 days). No patient mortality occurred. Pancreatic fistula developed in 9 cases (90%); however, all fistulas were grade A and resolved without surgical or radiological intervention. Nine patients remain well with no recurrence or new endocrine or exocrine dysfunction. Conclusion: Our results demonstrate that the outcomes of CP with IM-PJ are reasonable for prevention of pancreatic fistula following CP. PMID- 29184878 TI - Prognostic factors after curative resection hepatocellular carcinoma and the surgeon's role. AB - Purpose: Patient, surgical, and tumor factors affect the outcome after surgical resection for hepatocellular carcinoma (HCC). The surgical factors are only modifiable by the surgeon. We reviewed our experience with curative resection for HCC in terms of surgical factors. Methods: After analyses of the prospectively collected clinical data of 256 consecutive patients undergoing surgical resection for HCC, prognostic factors for disease-free survival (DFS) and overall survival (OS) were identified; all patients were stratified by tumor diameters > or <5 cm and their outcomes were compared. Results: Multivariate analyses showed that microvascular invasion, estimated blood loss, blood transfusion, and the number of tumors were independent adverse prognostic factors for DFS, whereas microvascular invasion, serum alpha fetoprotein, and tumor diameter were independent adverse prognostic factors for OS. Blood transfusion had borderline significance (P = 0.076). After stratification by tumor diameter, blood transfusion was only associated with poor DFS and OS in patients with tumor diameters > 5 cm. Conclusion: Tumor recurrence after liver resection for HCC depends on tumor status, bleeding, and transfusions, which subsequently lead to poor patient survival. Surgeons can help improve the prognosis of patients by minimizing blood loss and transfusion, particularly in patients with larger tumors. PMID- 29184879 TI - Three-year result of efficacy for type 2 diabetes mellitus control between laparoscopic duodenojejunal bypass compared with laparoscopic Roux-en-Y gastric bypass. AB - Purpose: The mechanism by which bariatric surgery facilitates diabetic control is still unknown. Duodenojejunal bypass supports the foregut theory; however, its efficacy when used alone is not yet established. Methods: During the period from January 2008 to December 2009, patients who underwent laparoscopic duodenojejunal bypass (LDJB) or laparoscopic Roux-en-Y gastric bypass (LRYGB) for type 2 diabetes mellitus (T2DM) with or without morbid obesity were included. Patients who had a follow-up for less than 3 years were excluded. Patient baseline characteristics, change of body weight, body mass index (BMI), glycosylated hemoglobin (HbA1c), and diabetic treatments were analyzed. Results: In total, 8 LDJB and 20 LRYGB patients were analyzed. The LDJB group had more number of male patients than the LRYGB group (LDJB 75% vs. LRYGB 30%, P = 0.030). Baseline BMI in the LRYGB group was higher than in the LDJB group (LDJB 27.0 +/- 2.5 vs. LRYGB 32.6 +/- 3.4, P < 0.001). Age, DM duration, baseline HbA1c, and C-peptide levels were similar. Longer operation time was needed to perform LDJB (LDJB 367.5 +/- 120.2 vs. LRYGB 232.9 +/- 41.1, P < 0.001), but no differences were observed in the hospital stay and complication rate between the 2 groups. At the third year of follow-up, the T2DM remission rate was observed in 40% of patients in the LRYGB group and 12.5% of patients in the LDJB group. Conclusion: LDJB is not an effective method for controlling T2DM compared with LRYGB. Foregut theory may not be the main mechanism of diabetic control during bariatric surgery. PMID- 29184880 TI - Histopathologic risk factors for lymph node metastasis in patients with T1 colorectal cancer. AB - Purpose: Evaluating the risk of lymph node metastasis (LNM) is critical for determining subsequent treatments following endoscopic resection of T1 colorectal cancer (CRC). This study analyzed histopathologic risk factors for LNM in patients with T1 CRC. Methods: This study involved 745 patients with T1 CRC who underwent endoscopic (n = 97) or surgical (n = 648) resection between January 2001 and December 2015 at the National Cancer Center, Korea. LNM in endoscopically resected patients, which could not be evaluated directly, was estimated indirectly based on follow-up results and histopathologic reports of salvage surgery. The relationships of depth of submucosal invasion, histologic grade, budding, vascular invasion, and background adenoma with LNM were evaluated statistically. Results: Of the 745 patients, 91 (12.2%) were found to be positive for LNM. Univariate and multivariate analyses identified deep submucosal invasion (P = 0.010), histologic high grade (P < 0.001), budding (P = 0.034), and vascular invasion (P < 0.001) as risk factors for LNM. Among the patients with one, two, three, and four risk factors, 6.0%, 18.7%, 36.4%, and 100%, respectively, were positive for LNM. Conclusion: Deep submucosal invasion, histologic high grade, budding, and vascular invasion are risk factors for LNM in patients with T1 colorectal cancer. If any of these risk factors are present, additional surgery following endoscopic resection should be determined after considering the potential risk of LNM and each patient's situation. PMID- 29184882 TI - Cutaneous metastasis: a rare phenomenon of colorectal cancer. AB - Cutaneous metastases from colorectal cancer are extremely rare and generally appear several years after diagnosis or resection of the primary tumor. Although this phenomenon is uncommon, it is very important and often indicates a poor prognosis. We present a case of a 76-year-old female patient with multiple cutaneous metastatic nodules on the back, just 1 month after resection of rectal cancer. Unfortunately, the patient gave up the follow-up treatment due to her age and poor physical condition; she died 3 months later. In view of its rarity of occurrence and lack of experience in treatment, we reviewed the literature and report as follows. PMID- 29184881 TI - Which patients with intestinal obstruction need surgery? The delta neutrophil index as an early predictive marker. AB - Purpose: Predicting the need for surgical intervention among patients with intestinal obstruction is challenging. The delta neutrophil index (DNI) has been suggested as a useful marker of immature granulocytes, which indicate an infection or sepsis. In this study, we evaluated the impact of the DNI as an early predictor of operation among patients with intestinal obstruction. Methods: A total of 171 patients who were diagnosed with postoperative intestinal obstruction were enrolled in this study. Medical records, including data for the initial CRP level, WBC count, and DNI were reviewed. Receiver operating characteristic (ROC) curves were generated to clarify the optimal DNI cutoff values for predicting an operation. Results: Among the 171 patients, 38 (22.2%) needed surgical intervention. The areas under the initial CRP, WBC, and DNI ROC curves were 0.460, 0.449, and 0.543, respectively. The optimal cutoff value for predicting further surgical intervention according to the initial DNI level was 4.3%. The accuracy of the cutoff value was 74.9%, the sensitivity was 23.7%, and the specificity was 89.5% (positive predictive value, 23.7%; negative predictive value, 89.5%). In the multivariate analysis, initial DNI levels >= 4.3% were significantly associated with surgical intervention (odd ratio, 3.092; 95% confidence interval, 1.072-8.918; P = 0.037). Conclusion: The initial DNI level in patients with intestinal obstruction may be a useful predictor for determining the need for surgical intervention. PMID- 29184883 TI - Small bowel obstruction caused by cryptorchidism in an adult. AB - Small bowel obstruction (SBO) is a common complication after abdominal surgery, and can occur due to many reasons. However, cryptorchidism can cause SBO in patients with no history of abdominal surgery. We report the case of a 67-year old man with SBO caused by adhesions between an undescended testis and the terminal ileum. PMID- 29184884 TI - Single port laparoscopic repair of sigmoid colon perforation during colonoscopy. AB - Colonic perforation during colonoscopy is a rare but lethal complication. Recently, it is usually managed with laparoscopic approach. Here we present our experience of single incision laparoscopic repair for sigmoid colon perforation during colonoscopy. A 57-year-old male patient presented with an acute sigmoid colon perforation event during diagnostic colonoscopy. Emergency operation was performed with transumbilical single incision laparoscopic exploration. The perforated site of sigmoid colon was primarily repaired with the curved endoscopic linear stapler. The patient was discharged after 5 days uneventfully. Single port laparoscopic repair is a safe and feasible method for the management of acute colonoscopic perforation during diagnostic colonoscopy. PMID- 29184885 TI - Sudden Infant Death Syndrome, Infection, Prone Sleep Position, and Vagal Neuroimmunology. AB - Recent findings suggest that infection (and sepsis) stand alone as the only plausible mechanism of causation of sudden infant death syndrome (SIDS) and accordingly achieves congruence with all clinicopathological and epidemiological findings. This review examines the role of infection in the pathogenesis of SIDS in the context of the major risk factor of prone sleep position. The study explores how sleep position could interact with the immune system and inflammatory response via vagal neural connections, which could play key roles in gut and immune homeostasis. A plausible and congruent clinicopathological and epidemiological paradigm is suggested. PMID- 29184886 TI - Expression Profiling of Ribosomal Protein Gene Family in Dehydration Stress Responses and Characterization of Transgenic Rice Plants Overexpressing RPL23A for Water-Use Efficiency and Tolerance to Drought and Salt Stresses. AB - Our previous findings on the screening of a large-pool of activation tagged rice plants grown under limited water conditions revealed the activation of Ribosomal Protein Large (RPL) subunit genes, RPL6 and RPL23A in two mutants that exhibited high water-use efficiency (WUE) with the genes getting activated by the integrated 4x enhancers (Moin et al., 2016a). In continuation of these findings, we have comprehensively characterized the Ribosomal Protein (RP) gene family including both small (RPS) and large (RPL) subunits, which have been identified to be encoded by at least 70 representative genes; RP-genes exist as multiple expressed copies with high nucleotide and amino acid sequence similarity. The differential expression of all the representative genes in rice was performed under limited water and drought conditions at progressive time intervals in the present study. More than 50% of the RP genes were upregulated in both shoot and root tissues. Some of them exhibited an overlap in upregulation under both the treatments indicating that they might have a common role in inducing tolerance under limited water and drought conditions. Among the genes that became significantly upregulated in both the tissues and under both the treatments are RPL6, 7, 23A, 24, and 31 and RPS4, 10 and 18a. To further validate the role of RP genes in WUE and inducing tolerance to other stresses, we have raised transgenic plants overexpressing RPL23A in rice. The high expression lines of RPL23A exhibited low Delta13C, increased quantum efficiency along with suitable growth and yield parameters with respect to negative control under the conditions of limited water availability. The constitutive expression of RPL23A was also associated with transcriptional upregulation of many other RPL and RPS genes. The seedlings of RPL23A high expression lines also showed a significant increase in fresh weight, root length, proline and chlorophyll contents under simulated drought and salt stresses. Taken together, our findings provide a secure basis for the RPL gene family expression as a potential resource for exploring abiotic stress tolerant properties in rice. PMID- 29184887 TI - Weak Molecular Interactions in Clathrin-Mediated Endocytosis. AB - Clathrin-mediated endocytosis is a process by which specific molecules are internalized from the cell periphery for delivery to early endosomes. The key stages in this step-wise process, from the starting point of cargo recognition, to the later stage of assembly of the clathrin coat, are dependent on weak interactions between a large network of proteins. This review discusses the structural and functional data that have improved our knowledge and understanding of the main weak molecular interactions implicated in clathrin-mediated endocytosis, with a particular focus on the two key proteins: AP2 and clathrin. PMID- 29184889 TI - The conceptualization of a Just-In-Time Adaptive Intervention (JITAI) for the reduction of sedentary behavior in older adults. AB - Low physical activity and high sedentary behavior in older adults can be addressed with interventions that are delivered through modern technology. Just In-Time Adaptive Interventions (JITAIs) are an emerging technology-driven behavior-change intervention type and capitalize on data that is collected via mobile sensing technology (e.g., smartphones) to trigger appropriate support in real-life. In this paper we integrated behavior change and aging theory and research as well as knowledge around older adult's technology use to conceptualize a JITAI targeting the reduction of sedentary behavior in older adults. The JITAIs ultimate goal is to encourage older adults to take regular activity breaks from prolonged sitting. As a proximal outcome, we suggest the number of daily activity breaks from sitting. Support provided to interrupt sitting time can be based on tailoring variables: (I) the current accumulated sitting time; (II) the location of the individual; (III) the time of the day; (IV) the frequency of daily support prompts; and (V) the response to previous support prompts. Data on these variables can be collected using sensors that are commonly inbuilt into smartphones (e.g., accelerometer, GPS). Support prompts might be best delivered via traditional text messages as older adults are usually familiar and comfortable with this function. The content of the prompts should encourage breaks from prolonged sitting by highlighting immediate benefits of sitting time interruptions. Additionally, light physical activities that could be done during the breaks should also be presented (e.g., walking into the kitchen to prepare a cup of tea). Although the conceptualized JITAI can be developed and implemented to test its efficacy, more work is required to identify ways to collect, aggregate, organize and immediately use dense data on the proposed and other potentially important tailoring variables. Machine learning and other computational modelling techniques commonly used by computer scientists and engineers appear promising. With this, to develop powerful JITAIs and to actualize the full potential of modern sensing technologies transdisciplinary approaches are required. PMID- 29184890 TI - Digital health is a cultural transformation of traditional healthcare. AB - Under the term "digital health", advanced medical technologies, disruptive innovations and digital communication have gradually become inseparable from providing best practice healthcare. While the cost of treating chronic conditions is increasing and doctor shortages are imminent worldwide, the needed transformation in the structure of healthcare and medicine fails to catch up with the rapid progress of the medical technology industry. This transition is slowed down by strict regulations; the reluctance of stakeholders in healthcare to change; and ignoring the importance of cultural changes and the human factor in an increasingly technological world. With access and adoption of technology getting higher, the risk of patients primarily turning to an accessible, but unregulated technological solution for their health problem is likely to increase. In this paper, we discuss how the old paradigm of the paternalistic model of medicine is transforming into an equal level partnership between patients and professionals and how it is aided and augmented by disruptive technologies. We attempt to define what digital health means and how it affects the status quo of care and also the study design in implementing technological innovations into the practice of medicine. PMID- 29184891 TI - The role of mHealth intervention on maternal and child health service delivery: findings from a randomized controlled field trial in rural Ethiopia. AB - Background: The provision of consistent and quality maternal and child health (MCH) services is a challenge for Ethiopia where most of the population lives in the rural setup. Health service delivery is constrained mainly by shortage of health professionals, meager resources, limited awareness among the society and bureaucratic procedures. Low health service utilization of antenatal care (ANC), delivery services, and postnatal care (PNC) are believed to contribute for high maternal and child mortality rates. Innovative approach like mHealth based technological intervention believed to alleviate such challenges in countries like ours. However, currently, there are few evidences that demonstrate the impact of mHealth technology applications on the level of service utilization. Therefore, the objective our study is to assess the role of mobile phone equipped with short message service (SMS) based data-exchange software linking community health workers to Health Centers in rural Ethiopia affect selected MCH outcomes. Methods: A community-based randomized control trial (RCT) was conducted in three woredas of Guraghe zone (Ezha, partial &Abeshge full intervention, Sodo Control). Mobile phones equipped with FrontlineSMS based, locally developed application was distributed to all health extension workers (HEWs) to both intervention woredas who filled maternal, child and stock related forms and submitted to the central server which in turn sends reminder about the scheduled date of ANC visit, expected date of delivery, PNC, immunization schedule and vaccine and contraceptive stock status. Moreover, in Abeshge, the voluntary health workers (vCHW) and HEW supervisors in both intervention woreda were given a phone to facilitate communication with the HEW. No mobile was offered to the control woreda.Pre [2012] and post [2013] intervention community based survey on mothers who have under 5 and under 1 year old child was done to assess the effect of the mobile intervention on selected MCH process indicators. Structured and pretested questionnaire was used to collect data and SPSS v16 statistical software was used for analysis. Results: Three thousand two hundred and forty mothers, 1,080 from each, were surveyed in the three woredas. The study revealed that the proportion of mothers receiving more than four ANC visits increased significantly in both intervention woredas. Besides, the rate of ANC delivered by HEWs improved in Ezha woreda (T1) (19.01% to 28.27%), proportions of deliveries attended by skilled health workers increased and home delivery decreased in all woredas; most pronounced increases in referrals from health post to health center by HEWs, reported in Ezha and Abeshge. The intervention also led to a significant reduction in stock-outs of preferred contraceptive products in Ezha (T1) from 16.96% to 8.24% but no change was observed in both contraceptive prevalence and immunization rates in the control and the other intervention woreda. Conclusions: The study confirmed the positive contribution of SMS based mobile phone intervention in most of the selected MCH service indicators, like improvement in the percent of recommended number of ANC visit, percentage of delivery attended by health workers and facilitating the work processes of the health workers in rural Ethiopia. PMID- 29184892 TI - BLOODR: blood donor and requester mobile application. AB - Background: With rapid increase in the usage of social networks sites across the world, there is also a steady increase in blood donation requests as being noticed in the number of posts on these sites such as Facebook and twitter seeking blood donors. Finding blood donor is a challenging issue in almost every country. There are some blood donor finder applications in the market such as Blood app by Red Cross and Blood Donor Finder application by Neologix. However, more reliable applications that meet the needs of users are prompted. Methods: Several software technologies including languages and framework are used to develop our blood-donor web application known as BLOODR application. These technologies comprise Ruby programming language (simply known as Ruby) along with JavaScript and PostgreSQL for database are used. Ruby on Rails (simply known as Rails) is an open source Web framework that makes it possible to quickly and easily create data-based web applications. Results: We show screenshots for the BLOODR application for different types of users including requester, donor, and administrator. Various features of the application are described and their needs of use are analyzed. If a patient needs a blood at a clinic, blood donors in vicinity can be contacted through using a clinic management service provided in this application. Registered donors will get notification for the blood requests only if their blood group is compatible with the requested blood type and in the same city/region. Then matching blood donors can go to the requesting clinic and donate. Conclusions: BLOODR application provides a reliable platform to connect local blood donors with patients. BLOODR creates a communication channel through authenticated clinics whenever a patient needs blood donation. It is a useful tool to find compatible blood donors who can receive blood request posts in their local area. Clinics can use this web application to maintain the blood donation activity. Future improvement of the BLOODR is explained. PMID- 29184888 TI - Targeting DNA Replication and Repair for the Development of Novel Therapeutics against Tuberculosis. AB - Mycobacterium tuberculosis is the etiological agent of tuberculosis (TB), an infectious disease which results in approximately 10 million incident cases and 1.4 million deaths globally each year, making it the leading cause of mortality from infection. An effective frontline combination chemotherapy exists for TB; however, this regimen requires the administration of four drugs in a 2 month long intensive phase followed by a continuation phase of a further 4 months with two of the original drugs, and is only effective for the treatment of drug-sensitive TB. The emergence and global spread of multidrug-resistant (MDR) as well as extensively drug-resistant (XDR) strains of M. tuberculosis, and the complications posed by co-infection with the human immunodeficiency virus (HIV) and other co-morbidities such as diabetes, have prompted urgent efforts to develop shorter regimens comprising new compounds with novel mechanisms of action. This demands that researchers re-visit cellular pathways and functions that are essential to M. tuberculosis survival and replication in the host but which are inadequately represented amongst the targets of current anti mycobacterial agents. Here, we consider the DNA replication and repair machinery as a source of new targets for anti-TB drug development. Like most bacteria, M. tuberculosis encodes a complex array of proteins which ensure faithful and accurate replication and repair of the chromosomal DNA. Many of these are essential; so, too, are enzymes in the ancillary pathways of nucleotide biosynthesis, salvage, and re-cycling, suggesting the potential to inhibit replication and repair functions at multiple stages. To this end, we provide an update on the state of chemotherapeutic inhibition of DNA synthesis and related pathways in M. tuberculosis. Given the established links between genotoxicity and mutagenesis, we also consider the potential implications of targeting DNA metabolic pathways implicated in the development of drug resistance in M. tuberculosis, an organism which is unusual in relying exclusively on de novo mutations and chromosomal rearrangements for evolution, including the acquisition of drug resistance. In that context, we conclude by discussing the feasibility of targeting mutagenic pathways in an ancillary, "anti-evolution" strategy aimed at protecting existing and future TB drugs. PMID- 29184893 TI - Global mHealth policy arena: status check and future directions. AB - In this review, we examine an important piece of the mHealth puzzle that has received scant attention-health policy. The question is whether health policy ultimately will serve to unite nations in advancing global mHealth or, as Mars and Scott suggested in 2010, keep nations isolated and ultimately making their policy decisions in "eHealth silos". Such a non-collaborative approach seriously hampers the potential for using mobile health technologies to deliver health care across borders, assuring individuals access to affordable, convenient, and quality healthcare in underserved regions. From a global perspective, mHealth policy review is difficult as some important policies may be subsumed in comprehensive planning and strategy documents. Political, environmental, economic, organizational, and technology disparities across nations represent a significant impediment to developing mHealth products and services that can be deployed globally. To date, there is modest evidence that such challenges are being addressed. Even though payers can encourage adoption of mHealth with financial incentives for use, it appears that payment or reimbursement tends to be a roadblock for almost all nations, whether they are emerging or developed. If payment for mHealth services is not guaranteed, business models will not be sustainable and providers will have fewer opportunities for scalability. Furthermore, because mHealth policies typically are subject to some type of government scrutiny and oversight, many product developers and entrepreneurs may turn elsewhere for their investments. Global resource scarcity also challenges optimal mHealth deployment, and governments seek to ensure improved population health outcomes as return on their mHealth investments. Unfortunately, such justification is difficult as evaluation methods simply have not kept pace with mHealth technology capability. Requisite measurement tools are sorely lacking when it comes to evaluating efficacy of mHealth interventions, due in part to insufficient research to inform development of needed measurement tools. Because most robust mHealth research trials have been conducted in the developed world with its impressive technology infrastructure and not in developing nations where the health needs are greatest, evaluation of mobile technology intervention from a global perspective tends to be insufficient to inform policy decisions. PMID- 29184894 TI - Effect of mHealth on modifying behavioural risk-factors of non-communicable diseases in an adult, rural population in Delhi, India. AB - Background: The rising trend of non-communicable diseases (NCDs) has led to a "dual burden" in low and middle-income (LAMI) countries like India which are still battling with high prevalence of communicable diseases. The incorporation of a target specially dedicated to NCDs within the goal 3 of the newly adopted Sustainable Development Goals indicates the importance the world now accords to prevention and control of these diseases. Mobile phone technology is increasingly viewed as a promising communication channel that can be utilized for primary prevention of NCDs by promoting behaviour change and risk factor modification. Methods: A "Before and After" Intervention study was conducted on 400 subjects, over a period of one year, in Barwala village, Delhi, India. An mHealth intervention package consisting of weekly text messages and monthly telephone calls addressing lifestyle modification for risk factors of NCDs was given to the intervention group, compared to no intervention package in control group. Results: After Intervention Phase, significant reduction was seen in behavioural risk factors (unhealthy diet and insufficient physical activity) in the intervention group compared to control group. Body mass index (BMI), systolic blood pressure and fasting blood sugar level also showed significant difference in the intervention group as compared to controls. Conclusions: Our study has demonstrated the usefulness of mHealth for health promotion and lifestyle modification at community level in a LAMI country. With the growing burden of NCDs in the community, such cost effective and innovative measures will be needed that can easily reach the masses. PMID- 29184895 TI - Impact of an iDevice application on student learning in an occupational therapy kinesiology course. AB - Background: As technology continues to evolve, and information is increasingly accessed through smartphones and tablets, it is essential for university faculty to reassess teaching methodologies. This study explored how use of an iDevice application (app) by participants enrolled in an entry-level occupational therapy kinesiology course affected student learning in the course. This iDevice app was developed through a collaboration between the lead author and the Department of Technology Enhanced Learning and Innovation at Augusta University. Methods: The iDevice app was released to the public via the Apple(r) App Store at the midpoint of the kinesiology course. All students were invited to use the app. Focus groups were conducted with 19 students recruited from the first year cohort of occupational therapy graduate students. These focus groups were conducted at the end of the semester once grades had been submitted. Results: Thematic analysis of focus group transcripts revealed three themes reflecting how participants perceived app use impacting their learning. Participants report the app facilitated learning through provision of visual content, serving as a reliable source of information, and generally supporting the learning process. The Kinesiology Pro Consult App provided on demand learning, allowing students to be more autonomous with their learning and take advantage of opportunities to learn anywhere and anytime. Finally, participants reported the app allowed them to be more efficient in their learning, possibly allowing more time for other courses. Conclusions: Mobile device apps that support student learning in specific content areas may provide positive benefits to student learning both in the specific course related to the app but also in other courses as a result of increased efficiency in learning. PMID- 29184896 TI - Formative evaluation on cultural tailoring breathing awareness meditation smartphone apps to reduce stress and blood pressure. AB - Background: Chronic stress is an independent risk factor for essential hypertension (EH), cardiovascular disease (CVD), and is sometimes confronted by mal-adaptive coping behaviors (e.g., stress eating, excessive alcohol consumption, etc.). Pre-essential hypertension (preEH) is the leading predictor of future EH status. Breathing awareness meditation (BAM) can result in clinically beneficial blood pressure (BP) reductions, though face-to-face sessions presents barriers to reach those in need. The purpose of this study was to identify if a culturally tailored approach is needed in the design and preferences between groups of preEH African American and White adults toward using a smartphone BAM app, the Tension Tamer (TT) app. Methods: TT includes audio delivered BAM instructions, real-time heart rate, feedback graphs and motivational reinforcement text messaging. Questionnaires and two focus groups each of African American and White adults, [n=34, mean age =43.1 years, (SD 13.8 years), 44.1% African American] were conducted to understand stress, EH knowledge, app usage along with feedback from a hands-on demonstration of TT. Grounded theory using NVivo 10 was used to develop themes and combined with the questionnaires in the analysis. Results: No racial differences were found in the analysis including app use scenarios, preferences, knowledge, technology use or the attitudes and acceptance toward mobile health (mHealth) programs. Reported stress was high for African Americans [PSS-4: mean 6.87 (SD 3.3) versus mean 4.56 (SD 2.6); P=0.03]. Four main themes were found: (I) stress was pervasive; (II) coping strategies were both positive and negative; (III) BAM training was easy to incorporated; and (IV) tracking stress responses was useful. Responses suggest that additional personalization of app interfaces may drive ownership and adherence to protocols. Measures and reports of heart rate monitoring while in session were favorably viewed with low issues with confidentiality or trust issues on collected session data. Conclusions: Results suggest that a culturally tailored approach may be unnecessary in the design of BAM apps. Further investigation is warranted for other racial groups, age ranges, and disease conditions. PMID- 29184897 TI - Deep learning for cardiac computer-aided diagnosis: benefits, issues & solutions. AB - Cardiovascular diseases are one of the top causes of deaths worldwide. In developing nations and rural areas, difficulties with diagnosis and treatment are made worse due to the deficiency of healthcare facilities. A viable solution to this issue is telemedicine, which involves delivering health care and sharing medical knowledge at a distance. Additionally, mHealth, the utilization of mobile devices for medical care, has also proven to be a feasible choice. The integration of telemedicine, mHealth and computer-aided diagnosis systems with the fields of machine and deep learning has enabled the creation of effective services that are adaptable to a multitude of scenarios. The objective of this review is to provide an overview of heart disease diagnosis and management, especially within the context of rural healthcare, as well as discuss the benefits, issues and solutions of implementing deep learning algorithms to improve the efficacy of relevant medical applications. PMID- 29184898 TI - Potential benefits of using ecological momentary assessment to study high-risk polydrug use. AB - Background: While studies have documented both the feasibility and acceptability of using ecological momentary assessment (EMA) to study drug use, there is little empirical research assessing participants' perceptions of utilizing this technology-driven approach. Methods: Participants were English-speaking persons >=18 years old who reported injection drug use and sequential (e.g., alcohol followed by opioid use) or simultaneous (i.e., injecting heroin and cocaine in one shot) polydrug use within 30 days recruited in San Diego, CA and Philadelphia, PA. Participants (N=36) completed two cell phone-based EMA simulations assessing mood, drug use, HIV risk behaviors, and daily activities, followed by semi-structured interviews that probed for potential benefits of participation over time. Qualitative analysis involved an iterative process of reviewing texts from the interviews to create a coding framework, which was then applied to all transcripts to identify themes. Results: Findings suggest participants may derive indirect benefits from participation in EMA studies including: improved self-worth from helping others; experiencing increased social support through utilization of the study-provided mobile device for non-research purposes; and most importantly, increased self-reflection, which could lead to therapeutic and intervention-like effects such as decreased substance use or reduced HIV risk. Conclusions: Participants identified a variety of potential benefits from participating in a study that utilizes EMA. This research suggests that benefits are highly salient for individuals involved in studies of polydrug use. PMID- 29184900 TI - Onto the bull's eye. AB - People set goals to improve their overall health and well-being. Unfortunately, people often lose motivation to achieve their goals because they fail to set proper goals. Goalify is a free mobile app with paid features that can help people set, achieve and maintain goals. It follows Locke and Latham strategies for successful goal setting. To gain greater control over their lives, we recommend readers to use a theory-based mobile app to set, log and achieve their goals.

PMID- 29184901 TI - Evaluating and improving recruitment and retention in an mHealth clinical trial: an example of iterating methods during a trial. AB - Background: Recruitment and retention strategy investigations in mHealth clinical trials are rare. Technology presents an opportunity to intensely and remotely evaluate recruitment, use of mobile apps, and retention, leading to new insights for continuous improvement of mHealth trials. The objective of this paper is to present a case study in which a trial evaluated and changed strategies during a clinical trial to improve recruitment, adherence to study protocols, and retention in the mHealth trial. Methods: In Fall 2015, the NUYou trial enrolled 150 college freshmen in an mHealth protocol. Three months after study initiation, NUYou struggled to meet recruitment goals and maintain anticipated usage levels of the study smartphone application. Two sets of data were collected to improve recruitment and retention: a survey about recruitment was sent to the target population and surveys regarding usability of the app was sent to the study sample. Survey results informed improvements in recruitment strategies, the study retention protocol, and the smartphone application. Results: Survey results revealed several insights including misunderstanding components of the trial by potential participants, low perceived usefulness of the app, and little recall or impact of the incentive structure. After implementation of user-centered improvements, the second cohort of NUYou recruitment in the fall of 2016 produced an equal sample size in 4 weeks less time. Winter quarter of 2016 compared to 2017 demonstrated an improvement in retention via app use and completion of weekly in-app surveys. Conclusions: Recruitment and retention in clinical trials continues to be a critical challenge and mHealth trials may present both unique challenges and opportunities. To our knowledge, this is the first study to describe a systematic evaluation followed by changes and further evaluation to recruitment, use of the mHealth application, adherence to study protocol, and retention during an mHealth clinical trial. Future work should adopt and explicitly study these processes to optimize both enrollment and retention in these types of trials to preserve validity and reliability of research results. PMID- 29184903 TI - International roadmap for artificial gravity research. AB - In this paper, we summarize the current and future research activities that will determine the requirements for implementing artificial gravity (AG) to mitigate the effects of long duration exposure to microgravity on board exploration class space vehicles. NASA and its international partners have developed an AG roadmap that contains a common set of goals, objectives, and milestones. This roadmap includes both ground-based and space-based projects, and involves human subjects as well as animal and cell models. It provides a framework that facilitates opportunities for collaboration using the full range of AG facilities that are available worldwide, and a forum for space physiologists, crew surgeons, astronauts, vehicle designers, and mission planners to review, evaluate, and discuss the issues of incorporating AG technologies into the vehicle design.

PMID- 29184905 TI - Frequency of In-Home Internet Use Among Prekidney and Postkidney Transplant Patients-Facilitators and Barriers to Use and Trends Over Time. AB - Background: As health-related communications become digitized, strategies to increase adoption of these Web-based platforms are needed. The purpose of this study was to assess facilitators and barriers to in-home Internet use among prekidney and postkidney transplant patients. Methods: A single center, cross sectional survey of 240 consecutive patients of all levels of technological proficiency who presented to an urban transplant center in the United States. The Patient Information and Technology Assessment consists of 6 demographic questions, 3 disease-related questions, and 8 technology-related questions. Results: Much of the sample was African American, male with a mean age of 51 years, and median income of $53 800/year. Logistic regression analysis was undertaken, and after adjusting for covariates, we found Smartphone ownership (odds ratio [OR], 4.94; 95% confidence interval [CI], 2.32-10.52), a higher number of Internet users in the home (OR, 2.00; 95% CI, 1.11-3.62), and having college education and beyond (OR, 4.88; 95% CI, 2.03-11.74) increased the likelihood of being a frequent Internet user. African American or Hispanic/Latino patients were less likely to be frequent Internet users compared with white patients (OR, 0.26 and 0.24, respectively, compared with whites, all P < 0.05). As the total number of people in the household increased, frequent Internet use decreased (OR, 0.52; 95% CI, 0.29-0.92). As age increased, reports of frequent Internet use decreased. Conclusions: Lower rates of Internet use among African Americans and Hispanic/Latinos in urban areas in the United States remains a problem despite a significant increase in access to the Internet and Smartphone ownership. The finding that Internet use increases as the number of Internet users in the household increases indicates that leveraging the patient's social support network and/or the development of patient information champion programs may aid with patient's adoption of health technology and patient engagement in self-care. PMID- 29184902 TI - Vertebrate food products as a potential source of prion-like alpha-synuclein. AB - The aberrant aggregation of the protein alpha-synuclein is thought to be involved in Parkinson's disease (PD). However, the factors that lead to initiation and propagation of alpha-synuclein aggregation are not clearly understood. Recently, the hypothesis that alpha-synuclein aggregation spreads via a prion-like mechanism originating in the gut has gained much scientific attention. If alpha synuclein spreads via a prion-like mechanism, then an important question becomes, what are the origins of this prion-like species? Here we review the possibility that alpha-synuclein aggregation could be seeded via the ingestion of a prion like alpha-synuclein species contained within food products originating from vertebrates. To do this, we highlight current evidence for the gut-to-brain hypothesis of PD, and put this in context of available routes of alpha-synuclein prion infectivity via the gastrointestinal (GI) tract. We then discuss meat as a ready exogenous source of alpha-synuclein and how certain risk factors, including inflammation, may allow for dietary alpha-synuclein to pass from the GI lumen into the host to induce pathology. Lastly, we review epidemiological evidence that dietary factors may be involved in PD. Overall, research to date has yet to directly test the contribution of dietary alpha-synuclein to the mechanism of initiation and progression of the disease. However, numerous experimental findings, including the potent seeding and spreading behavior of alpha-synuclein fibrils, seem to support, at least in part, the feasibility of an infection with a prion alpha-synuclein particle via the GI tract. Further studies are required to determine whether dietary alpha-synuclein contributes to seeding pathology in the gut. PMID- 29184906 TI - Parvovirus B19 in the Context of Hematopoietic Stem Cell Transplantation: Evaluating Cell Donors and Recipients. AB - Background: Parvovirus B19 (B19V) is a common human pathogen, member of the family Parvoviridae. Typically, B19V has been found to infect erythroid progenitors and cause hematological disorders, such as anemia and aplastic crisis. However, the persistence of genomic deoxyribonucleic acid (DNA) has been demonstrated in tonsils, liver, skin, brain, synovial, and testicular tissues as well as bone marrow, for both symptomatic and asymptomatic subjects. Although the molecular and cellular mechanisms of persistence remain undefined, it raises questions about potential virus transmissibility and its effects in the context of allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. Methods: With this aim, we retrospectively screened allogeneic stem cell donors from 173 patients admitted for allo-HSCT from January 2008 to May 2013 using a seminested polymerase chain reaction approach. Results: We found 8 positive donor samples, yielding a 4.6% of parvovirus prevalence (95% confidence interval, 2.36 8.85). Pre- and post-HSCT samples (n = 51) from the 8 recipients of the positive donors were also investigated, and 1 case exhibited B19V DNA in the post-HSCT follow-up (D + 60). Direct DNA sequencing was performed to determine the genotype of isolates and classification, performed by phylogenetic reconstruction, showed a predominance of genotype 1a, whereas the rare genotype 3b was detected in 2 additional patients. By molecular cloning, different B19V 1a substrains polymorphisms were evidenced in the single case in which donor and its recipient were B19V+. Conclusions: Our results suggest that HSCT allografts are not a main source for B19V transmission, pointing to potential events of reinfection or endogenous viral reactivation. PMID- 29184907 TI - Comparative Assessment of Anti-HLA Antibodies Using Two Commercially Available Luminex-Based Assays. AB - Background: Allospecific anti-HLA antibodies (Abs) are associated with rejection of solid organ grafts. The 2 main kits to detect anti-HLA Ab in patient serum are commercialized by Immucor and One Lambda/ThermoFisher. We sought to compare the performance of both platforms. Methods: Background-adjusted mean fluorescence intensity (MFI) values were used from both platforms to compare sera collected from 125 pretransplant and posttransplant heart and lung transplant recipients. Results: Most HLA class I (94.5%) and HLA class II (89%) Abs with moderate to high MFI titer (>=4000) were detected by both assays. A modest correlation was observed between MFI values obtained from the 2 assays for both class I (r = 0.3, r2 = 0.09, P < 0.0001) and class II Ab (r = 0.707, r2 = 0.5, P < 0.0001). Both assays detected anti-class I and II Ab that the other did not; however, no specific HLA allele was detected preferentially by either of the 2 assays. For a limited number of discrepant sera, dilution resulted in comparable reactivity profiles between the 2 platforms. Conclusions: Immucor and One Lambda/ThermoFisher assays have a similar, albeit nonidentical, ability to detect anti-HLA Ab. Although the correlation between the assays was present, significant variances exist, some of which can be explained by a dilution-sensitive "prozone" effect. PMID- 29184908 TI - Hypothesis: Potential Utility of Serum and Urine Uromodulin Measurement in Kidney Transplant Recipients? AB - Seventy years after its discovery, studies of the myriad properties, and potential disease associations of uromodulin are now burgeoning. Although normative ranges for serum/plasma uromodulin concentrations were established over 30 years ago, their external validation occurred only in very recent, larger studies. As tubular function indices, serum and urinary uromodulin may be more sensitive indicators of kidney graft dysfunction undetected by glomerular filtration markers, or proteinuria. Moreover, 2 sizable, just published longitudinal reports revealed that lower serum uromodulin levels were associated with cardiovascular disease (CVD) outcomes, total mortality, and infectious disease deaths, in patients with known or suspected coronary heart disease. Preliminary longitudinal studies have reported that reduced levels of plasma or serum uromodulin were linked to progression to end-stage renal disease in chronic kidney disease patients, and graft failure in kidney transplant recipients (KTRs). Conflicting data on the associations, or lack thereof, between lower urinary uromodulin concentrations and accelerated loss of renal function, or renal failure, in nontransplant chronic kidney disease patients, are perhaps due, in part, to analytical limitations in determining urine uromodulin. Potential longitudinal associations between serum and urinary uromodulin concentrations, and CVD outcomes, graft failure, and all-cause mortality, await validation in large, diverse cohorts of chronic KTRs. Taking advantage of an efficient case cohort design scheme, we demonstrate how the completed FAVORIT clinical trial cohort might be ideally suited to evaluate these associations. Using available case-cohort sample data, statistical power simulations are provided to detect relative risk estimates of 1.50 for CVD (n = 309 events), 1.56 for graft failure (n = 223 events) or 1.50 for death from any cause (n = 320 events), comparing values below the median, to values equal to or above the median for serum uromodulin values. Edifying data such as these would advance our understanding of the hypothetical utility of uromodulin measurement in KTRs considerably. PMID- 29184909 TI - Gut Permeability and Glucose Absorption Are Affected at Early Stages of Graft Rejection in a Small Bowel Transplant Rat Model. AB - Background: Intestinal transplantation (ITx) faces many challenges due to the complexity of surgery and to the multiple immunological reactions that lead to the necessity of rigorous follow-up for early detection of acute cellular rejection (ACR). Our aim was to determine the kinetics of ACR using an experimental ITx model, with emphasis in the characterization of the process using different approaches, including the use of functional assays of absorptive and barrier function. Methods: ITx in rats conducting serial sampling was performed. Clinical monitoring, graft histology, proinflammatory gene expression, and nitrosative stress determination were performed. Also, glucose absorption, barrier function using ovalbumin translocation, and contractile function were analyzed. Results: The model used reproduced the different stages of ACR. Allogeneic ITx recipients showed signs of rejection from postoperative day (POD) 5, with increasing severity until 12 POD. Histological evaluation showed mild rejection in early sampling and severe rejection at late stages, with alterations in all graft layers. IL-6, CXCL 10, IFNg, and nitrite plasmas levels showed behavior coincident with histopathology. Remarkably, allogeneic grafts showed a marked alteration of glucose absorptive capacity from POD 5 that was sustained until endpoint. Coincidently, barrier function alteration was evidenced by luminal ovalbumin translocation to serum. Contractile function was progressively impaired along ACR. Conclusions: Glucose absorption and barrier function are altered at early stages of ACR when histological alterations or gene expression changes were much subtle. This observation may provide simple evaluation tools that could be eventually translated to the clinics to contribute to early ACR diagnosis. PMID- 29184910 TI - Adapting the Surgical Apgar Score for Perioperative Outcome Prediction in Liver Transplantation: A Retrospective Study. AB - Background: The surgical Apgar score (SAS) is a 10-point scale using the lowest heart rate, lowest mean arterial pressure, and estimated blood loss (EBL) during surgery to predict postoperative outcomes. The SAS has not yet been validated in liver transplantation patients, because typical blood loss usually exceeds the highest EBL category. Our primary aim was to develop a modified SAS for liver transplant (SAS-LT) by replacing the EBL parameter with volume of red cells transfused. We hypothesized that the SAS-LT would predict death or severe complication within 30 days of transplant with similar accuracy to current scoring systems. Methods: A retrospective cohort of consecutive liver transplantations from July 2007 to November 2013 was used to develop the SAS-LT. The predictive ability of SAS-LT for early postoperative outcomes was compared with Model for End-stage Liver Disease, Sequential Organ Failure Assessment, and Acute Physiology and Chronic Health Evaluation III scores using multivariable logistic regression and receiver operating characteristic analysis. Results: Of 628 transplants, death or serious perioperative morbidity occurred in 105 (16.7%). The SAS-LT (receiver operating characteristic area under the curve [AUC], 0.57) had similar predictive ability to Acute Physiology and Chronic Health Evaluation III, model for end-stage liver disease, and Sequential Organ Failure Assessment scores (0.57, 0.56, and 0.61, respectively).Seventy-nine (12.6%) patients were discharged from the ICU in 24 hours or less. These patients' SAS-LT scores were significantly higher than those with a longer stay (7.0 vs 6.2, P < 0.01). The AUC on multivariable modeling remained predictive of early ICU discharge (AUC, 0.67). Conclusions: The SAS-LT utilized simple intraoperative metrics to predict early morbidity and mortality after liver transplant with similar accuracy to other scoring systems at an earlier postoperative time point. PMID- 29184911 TI - Kidney Transplant Recipients With Primary Membranous Glomerulonephritis Have a Higher Risk of Acute Rejection Compared With Other Primary Glomerulonephritides. AB - Background: Despite being the leading cause of graft failure, there is a lack of published data about the rates of rejection in kidney transplant patients with glomerulonephritis as the cause of end-stage renal disease. Methods: We examined all consecutive adult (>18 years) renal transplant recipients with biopsy-proven native renal glomerular disease who underwent kidney transplant between 1994 and 2013. Glomerulonephritis groups included were IgA nephropathy (IgAN) (N = 306), focal segmental glomerulosclerosis (FSGS) (N = 298), membranous nephropathy (MN) (N = 81), and lupus nephritis (LN) (N = 177). Results: In the total cohort of 862 patients, 363 patients had an episode of acute rejection during the follow-up period of 19 years (incidence rate of 7.2% per year). Forty-five of 81 patients with MN had an episode of acute rejection during the follow-up period. Patients with MN had significantly higher incidence of acute rejection (12.1 per 100 person years, P < 0.05) in comparison to IgAN (7.2 per 100 person years), FSGS (7.4 per 100 person years), and LN (7.9 per 100 person years). Patients with MN had 1.9 times higher risk of developing acute rejection after transplant in comparison to IgAN (P < 0.005). In patients with MN, 33 of 45 (73.3%) rejection events were acute cellular rejection, 8 (17.8%) of 45 were acute antibody mediated rejection and 6 of 45 (13.3%) were combined cellular and antibody mediated acute rejection. Despite higher rates of acute rejection, 10-year allograft survival was similar in all subgroups. Conclusions: Patients with MN have higher incidence of acute rejection after kidney transplant but have similar 10-year allograft survival in comparison to the other glomerular diseases like IgAN, FSGS, and LN. PMID- 29184912 TI - Liver Transplantation From Donors With a History of Malignancy: A Single-Center Experience. AB - Background: The demand for transplantable organs exceeds donor organ supply. Transplantation of organs from donors with a history of malignancy remains controversial and the transmission of cancer in liver transplant recipients has not been sufficiently examined. Methods: From 2002 until 2017, 83 livers from donors with a history of malignancy were transplanted at the University Hospital Essen, Germany. Donor and recipient data, type of malignancy, tumor-free interval at organ procurement, and follow-up data were analyzed. Results: Nine different tumor sites (central nervous system [n = 27], genitourinary [n = 24], breast [n = 10], skin [n = 8], colorectal [n = 5], lung [n = 3], hemato-oncological [n = 3], thyroid [n = 2], and larynx [n = 1]) were detected in 83 donors. The majority (58%) of donors had tumor-free intervals of less than 5 years versus 19% of 6 to 10 years versus 23% over 10 years. The risk of tumor transmission from donors was assessed as low in 44 (53%), intermediate in 28 (34%), and high in 11 (13%) cases. During median follow-up of 19.9 (0-155) months, none of the recipients developed donor-transmitted malignancy. Conclusions: Liver transplantation with organs from donors with a medical history of malignancy is feasible, and the risk of donor-transmitted malignancy appears to be low in this single-center analysis. A careful selection of donors remains mandatory and can expand the donor pool. PMID- 29184914 TI - Genomic links between blast exposure, brain injury, and Alzheimer disease.

AB - In aggressive cases, endometriosis can perturb the urogenital tract, in particular the ureter, which can potentially result in ureteral compression or stenosis. Even though this is rare, consequences are dramatic, such as hydronephrosis or organ failure. The present standard intervention comprises the resection of affected tissues and endometriosis foci combined with adjuvant hormonal therapy. When the ureter does not recover, ureteral reimplantation is required.

Materials and Methods This retrospective study examined 202 patients who during a 2-year period from 2011 and 2012 underwent surgical treatment for chronic subdural hematoma (CSDH). Information on patient age, sex, alcohol consumption, anticoagulant/antiplatelet treatment, history of head trauma, Glasgow coma scale (GCS), neurological symptoms, laterality of CSDH, and surgical technique was retrieved from patient charts. Results Overall, 27 out of 202 patients had a recurrence of CSDH and re evacuation of the hematoma was performed. In all patients recurrence of neurological symptoms preceded the planned postoperative control brain CT 4 to 6 weeks after primary surgery. Conclusion Routinely postoperative control brain CT scan 4 to 6 weeks after the evacuation of a CSDH has no clinical value.

AB - Rectal hemorrhage should be evaluated within a wide spectrum ranging from benign diseases to a malignant process. Especially, the melanomas of rectum are detected at an advanced stage when diagnosed since the present symptoms of rectal melanomas are similar. The question of what will be the surgical approach with MR, CT, and PET-CT imaging methods performed after histopathological diagnosis still conserves its topicality. PET-CT is a good imaging method for determination of distant metastasis and lymphatic involvement. In the present case, a patient with early-stage rectal melanoma was treated with APR. No relapse/metastasis was detected during the 18-month follow-up. The aggressive course of the disease and its low response rates to medical treatments may cause the surgical approaches to be more extensive. PMID- 29184919 TI - Why pregnenolone and progesterone, two structurally similar steroids, exhibit remarkably different cocrystallization with aromatic molecules. AB - Selective binding of steroid molecules is of paramount importance for designing drugs that can target the biological pathways of only individual steroids. From this perspective, it is remarkable that progesterone (PRO) and pregnenolone (PRE), two structurally similar steroids, demonstrate a dramatically different propensity to interact with aromatic molecules. It has been recently reported that, in solid-state cocrystallization, PRO forms cocrystals with a wide variety of aromatic systems whereas PRE cocrystallizes only with a few. In this work, a simple yet effective computational procedure was developed to explain the fundamental origins of this surprising phenomenon. This procedure enables a direct comparison of the strength of intermolecular binding in the structurally similar cocrystals of PRO and PRE by generating experimentally inaccessible meta stable cocrystals of PRE that closely resemble those observed for PRO. Direct comparative analysis shows that interactions between the alpha-face of the steroid and the pi-electrons of aromatic molecules, the focus of previous studies, are not sufficiently different to explain the cocrystallization behavior of PRO and PRE. Instead, the observed difference is attributed to the different stabilities of the cocrystals relative to their pure components: organic and steroid crystals. It is calculated that the cocrystallization process is thermodynamically favorable in the case of PRO and unfavorable in the case of PRE. Furthermore, strong hydrogen bonds in the pure PRE crystal appear to be the major factor that makes the cocrystallization of PRE energetically unfavorable for a wide range of aromatic molecules. The fundamental analysis performed in this work has important practical implications for designing new steroid containing crystals, selective biomolecular steroid receptors, and steroid specific drugs. It suggests that a strategy for the selective binding of steroids should focus primarily on tuning the strength of hydrogen bonding.

AB - Background: Malaria mosquitoes form mating swarms around sunset, often at the same locations for months or years. Unfortunately, studies of Anopheles swarms are rare in East Africa, the last recorded field observations in Tanzania having been in 1983. Methods: Mosquito swarms were surveyed by trained volunteers between August-2016 and June-2017 in Ulanga district, Tanzania. Identified Anopheles swarms were sampled using sweep nets, and collected mosquitoes killed by refrigeration then identified by sex and taxa. Sub-samples were further identified by PCR, and spermatheca of females examined for mating status. Mosquito ages were estimated by observing female ovarian tracheoles and rotation of male genitalia. GPS locations, types of swarm markers, start/end times of swarming, heights above ground, mosquito counts/swarm, and copulation events were recorded. Results: A total of 216 Anopheles swarms were identified, characterized and mapped, from which 7,142 Anopheles gambiae s.l and 13 Anopheles funestus were sampled. The An. gambiae s.l were 99.6% males and 0.4% females, while the An. funestus were all males. Of all An. gambiae s.l analyzed by PCR, 86.7% were An. arabiensis, while 13.3% returned non-amplified DNA. Mean height (+/-SD) of swarms was 2.74+/-0.64m, and median duration was 20 (IQR; 15-25) minutes. Confirmed swarm markers included rice fields (25.5%), burned grounds (17.2%), banana trees (13%), brick piles (8.8%), garbage heaps (7.9%) and ant-hills (7.4%). Visual estimates of swarm sizes by the volunteers was strongly correlated to actual sizes by sweep nets (R=0.94; P=<0.001). All females examined were nulliparous and 95.6% [N=6787] of males had rotated genitalia, indicating sexual maturity. Conclusions: This is the first report of Anopheles swarms in Tanzania in more than three decades. The study demonstrates that the swarms can be identified and characterized by trained community-based volunteers, and highlights potential new interventions, for example targeted aerosol spraying of the swarms to improve malaria control.

AB - The development of sensing systems for the measurement of small molecules is an active area of research. A sensor based approach for the measurement of metabolites can potentially provide the simplicity and portability required for widespread use. Rapid detection and quantitation of small-molecule metabolites can potentially emerge as an effective way to link the metabolite profile to the disease state. Surface plasmon resonance (SPR) combined with molecular recognition elements to deliver high specificity is a sensing platform that has been widely applied for a large range of biomolecules. However, direct detection of small molecules with SPR challenges the refractive index based detection mechanism. The work described here combines a periplasmic binding protein for recognition with target modified gold nanoparticles (AuNPs) in a competitive assay format for folic acid (FA) detection. Specifically, a SPR imaging substrate containing immobilized folate binding protein (FBP) is used to measure the adsorption of FA conjugated AuNPs. The immobilization of the FBP and the binding of the FA conjugated AuNPs are characterized and optimized. It is shown that free FA in solution can be quantitatively measured by competition for the surface binding sites with the functionalized AuNPs. We demonstrate that the dynamic range can be lowered from micromolar to nanomolar by simply decreasing the concentration of FA conjugated AuNPs, thus lowering the limit of detection to 2.9 nM. This type of competitive assay can be applied to a range of small molecules, which paves the way for future multiplexed analysis of metabolites using SPR. PMID- 29184921 TI - The effects of glycine, TMAO and osmolyte mixtures on the pressure dependent enzymatic activity of alpha-chymotrypsin. AB - High pressure is an important feature of certain natural environments, such as the deep sea where pressures up to about 1000 bar are encountered. Further, pressure effects on biosystems are of increasing interest for biotechnological applications, such as baroenzymology. We studied the effect of two different natural osmolyte mixtures, with major components being glycine and trimethylamine N-oxide (TMAO), on the activity of alpha-chymotrypsin, using high-pressure stopped-flow methodology in combination with fast UV/Vis detection. We show that pressure is not only able to drastically enhance the catalytic activity and efficiency of the enzyme, but also that glycine has a significant and diverse effect on the enzymatic activity and volumetric properties of the reaction compared to TMAO. The results might not only help to understand the modulation of enzymatic reactions by natural osmolytes, but also elucidate ways to optimize enzymatic processes in biotechnological applications.

AB - A morphology transformation of hybrid liposomes was shown to occur from spherical vesicles to tubular micelles when increasing the ratio of the metal complex lipid present. Phase transition temperatures increased while viscosities decreased, indicating that the hybrids exhibit stronger interaction between heads but weaker interaction between alkyl chains than occurs in pristine liposomes. PMID- 29184923 TI - Controlling N2O formation during regeneration of NOx storage and reduction catalysts: from impact of platinum-group metal type to rational utilization. AB - Herein, we report an effective strategy for minimization of N2O emissions based on elucidating the impact of the type of platinum-group metals (PGMs = Pt, Pd, or Rh) on by-product formation during regeneration of PGM-BaO/Al2O3 catalysts. The significant differences in N2O or NH3 formation were thoroughly investigated from the perspective of an in situ reaction. Kinetic analysis of NO reduction by CO shows different turnover frequency and apparent activation energy values over these catalysts. The results reveal that the apparent kinetics is dependent on the type of platinum-group metal chosen. In situ DRIFTS data indicate that the unique adsorption behaviors of reactants via which they access each PGM essentially determine their individual reaction kinetics. The preferential adsorption of NO or CO molecules on the PGM surface controls the dominant intermediate (NOad/Nad, COad, or NCOad) species, which is a major factor responsible for various yields of N2O and NH3 during the rich period. Finally, a feasible strategy has been proposed via optimizing catalyst formulation to effectively control the N2O emissions.

AB - DNA templates containing 5-hydroxymethyluracil or 5-hydroxymethylcytosine were used in an in vitro transcription assay with RNA polymerase from Escherichia coli. A strong enhancement of transcription was observed from DNA containing the Pveg promoter whereas a decrease was observed from DNA containing the rrnB P1 promoter, suggesting that they may act as epigenetic marks.

PMID- 29184926 TI - State-to-state mode specificity in H + DOH(nuOH = 1) -> HD + OH(nu2 = 0) reaction: vibrational non-adiabaticity or local-mode excitation? AB - It is well established that chemical reactions often involve only a small number of atoms near the reaction site, and the remainder of the reactant molecules are mostly spectators. It is thus of great importance to understand the role played by the active as well as spectator modes in chemical dynamics. In this work, we examine in great detail the influence of reactant modes on the reactivity and product state distribution, using a four-atom prototypical reaction as the example. State-of-the-art full-dimensional state-to-state quantum dynamics reveal a startling observation in which the DOH(nuOH = 1) molecule reacts with a H atom to produce a vibrationless OH product. This is surprising because OH is considered as a spectator in this reaction and its internal energy should be sequestered throughout the reaction. By careful analysis within the local-mode regime, we demonstrate that the surprising reactivity is not due to vibrational non-adiabaticity during the reaction. Rather, it can be attributed to a small OD excited local-mode component in the reactant wavefunction. The quantum state resolved dissection of this prototype reaction helps to advance our understanding of larger reactive systems.

The Zn-Ln clusters exhibit interesting nano-square-like structures. Their visible and NIR luminescence properties were investigated. PMID- 29184928 TI - C-S bond induced ultrafine SnS2 dot/porous g-C3N4 sheet 0D/2D heterojunction: synthesis and photocatalytic mechanism investigation. AB - The construction of novel heterojunctions is precisely deemed to be an effective strategy to facilitate photo-generated carrier separation and boost charge utilization efficiency, leading to much enhanced photocatalytic activities. Herein, in situ of growing ultrafine SnS2 nanoparticles on a porous g-C3N4 sheet (SnS2/g-C3N4) 0D/2D heterojunction was achieved via a low-temperature solvothermal process. Combined with various characterization techniques, it is revealed that SnS2 dots with a diameter of 3 nm distribute evenly on the surface of the g-C3N4 substrate with strong C-S bonds. The photocatalytic activities are evaluated by the degradation of Rhodamine B (RhB) under visible light irradiation, showing a much enhanced photodegradation efficiency of 96.8% over 105 min irradiation and an enhanced reaction rate constant (k = 3.3% min-1, 8.25 and 8.05 times that of pure g-C3N4 and SnS2). The improved photocatalytic activities could be ascribed to the efficient electron-hole separation of porous g-C3N4, which is caused by the ultrafine SnS2 dots linked with the g-C3N4 substrate through C-S bonds. Therefore, the recombination efficiency is decreased. In addition, reactive active species trapping experiments prove that the superoxide radical (O2-) and holes (h+) are the main active species in this photocatalytic system. The photodegradation mechanism of the SnS2/g-C3N4 heterojunction is analyzed and demonstrated in detail. PMID- 29184929 TI - Embedding liquid lasers within or around aqueous microfluidic droplets. AB - In this paper, we demonstrate the incorporation of dye-based liquid lasers within or around flowing aqueous microfluidic droplets. In particular, we use dye solutions in benzyl alcohol, and either disperse an ensemble of small (~20 MUm) lasing droplets within large (~500 MUm) aqueous droplets flowing in a simple glass capillary-based microfluidic device, or 'wrap' a thin (~10 MUm) lasing benzyl alcohol shell around larger (~560 MUm) microfluidic aqueous droplets. We experimentally and theoretically characterize the lasing behavior in both cases, which is supported by whispering-gallery mode (WGM) optical resonances at the droplet interfaces. We showcase a simple application of our method, which highlights the advantages of having embedded, spatially segregated laser sources within a droplet containing a model analyte solution. With this method, each microfluidic droplet now functions not only as an isolated experiment flask, but is also capable of on drop sensing that exploits WGM-based lasing, thus expanding the possibilities for online monitoring of biophysical/biochemical processes and sensitive detection of biomolecules in droplet-based microfluidics. PMID- 29184930 TI - Bimetallic Ru(ii) and Os(ii) complexes based on a pyrene-bisimidazole spacer: synthesis, photophysics, electrochemistry and multisignalling DNA binding studies in the near infrared region. AB - We report in this paper the synthesis, characterization, photophysical and electrochemical properties, and detailed DNA binding affinities of two homobimetallic Ru(ii) and Os(ii) complexes derived from a new bridging ligand consisting of two pyridyl-imidazole coordinating units rigidly coupled with a central pyrene moiety. The structure of the diruthenium complex was confirmed by X-ray crystallography. Both complexes exhibit luminescence at room temperature from their 3MLCT states, with lifetimes of tau1 = 12.6 ns and tau2 = 48.8 ns for the Ru(ii) complex (1) and tau1 = 23.7 ns for the Os(ii) complex (2). For 2, the luminescence maximum stretches to the NIR region, which is suitable for potential biological applications. Both complexes exhibit two successive one-electron reversible metal-centered oxidations in the positive potential window. Computational studies employing DFT and TD-DFT methods were also performed to assign the experimentally observed optical spectral bands in the complexes. The binding affinities of the complexes towards DNA were thoroughly investigated through a variety of techniques, viz. absorption, luminescence, excited state lifetime, circular dichroism, thermal denaturation, viscosity measurement, and relative DNA binding studies using ethidium bromide. Finally, molecular docking studies were also carried out to visualize the modes of interaction between the complexes and DNA.

AB - A double-functionalized polymer monolithic column was fabricated within the confines of a stainless-steel column (50 mm * 4.6 mm i.d.) via a facile method using iron porphyrin, ionic liquid (1-allyl-3-methylimidazolium chloride) and 1,10-decanediol dimethacrylate as tri-monomers; ethylene dimethacrylate as a crosslinker; polyethylene glycol 400 and N,N-dimethylformamide as co-porogens; benzoyl peroxide and N,N-dimethyl aniline as the redox initiation system. Results obtained from scanning electron microscopy, nitrogen adsorption-desorption, and mercury intrusion porosimetry confirmed the uniform pore structure and the pore size distribution of macro-pores. The home-made monolith was further characterized by elemental analysis to investigate the elemental composition of Fe supplied by iron porphyrin, confirming the synthetic process. The resulting optimized monolithic column was used as the stationary phase in high performance liquid chromatography for separating proteins, such as mixture of standard proteins, egg white, and human plasma, exhibiting good selectivity and high performance. It is worth noting that the home-made double-functionalized polymer monolithic column shows excellent selectivity for fractionation separation of human plasma proteins, and it is a promising separation tool for complex bio samples in proteomic research.

AB - The conveniently obtained water-soluble small-molecule L1-5 were selective for RNA with remarkable "off-on" two-photon fluorescence responses in vitro and in vivo, showing that L1-5 can surprisingly stain mitochondria or nucleoli individually with orange fluorescence under different focal lengths. Compounds L6 8 were prepared, for comparison, to further explore the mechanism of the binding of L1-5 with RNA, which revealed that the synergistic effect of the amino group and the pyridinium cation played a significant role in distinct cell imaging.

Additionally, the results of DFT calculations suggested contributions from an ambiphilic resonance structure, similar to the corresponding aluminum and gallium derivatives. PMID- 29184934 TI - Extracellular vesicles, exosomes and shedding vesicles in regenerative medicine - a new paradigm for tissue repair. AB - Tissue regeneration by stem cells is driven by the paracrine activity of shedding vesicles and exosomes, which deliver specific cargoes to the recipient cells. Proteins, RNA, cytokines and subsequent gene expression, orchestrate the regeneration process by improving the microenvironment to promote cell survival, controlling inflammation, repairing injury and enhancing the healing process. The action of microRNA is widely accepted as an essential driver of the regenerative process through its impact on multiple downstream biological pathways, and its ability to regulate the host immune response. Here, we present an overview of the recent potential uses of exosomes for regenerative medicine and tissue engineering. We also highlight the differences in composition between shedding vesicles and exosomes that depend on the various types of stem cells from which they are derived. The conditions that affect the production of exosomes in different cell types are deliberated. This review also presents the current status of candidate exosomal microRNAs for potential therapeutic use in regenerative medicine, and in applications involving widely studied organs and tissues such as heart, lung, cartilage and bone. PMID- 29184935 TI - In situ synthesis of Bi nanoflakes on Ni foam for sodium-ion batteries. AB - We report a facile method to in situ synthesize Bi nanoflakes on Ni foam (Bi/Ni) via a replacement reaction, which can directly work as an anode for sodium-ion batteries (SIBs) without further treatment. The integrated nanoflake structure of the Bi/Ni effectively accommodates the dramatic volume changes of Bi during cycling, and favors both electron and Na+ transport through the electrode. This ensures high cycling performance and good rate capability. The sodiation/desodiation of Bi is revealed to be composed of two successive steps: Bi <-> NaBi and NaBi <-> Na3Bi. This facile strategy will encourage more investigations into the design and synthesis of integrated electrodes for high performance SIBs. PMID- 29184936 TI - The shape of the electronic circular dichroism spectrum of (2,6 dimethylphenyl)(phenyl)methanol: interplay between conformational equilibria and vibronic effects. AB - Comparison between chiroptical spectra and theoretical predictions is the method of choice for the assignment of the absolute configuration of chiral compounds in solution. Here we report the case of an apparently simple biarylcarbinol, whose electronic circular dichroism (ECD) in the 1Lb region exhibits a peculiar alternation of negative and positive bands. Adopting Density Functional Theory, and describing solvent effects with implicit methods, we found three stable conformers in ethanol, each of them with two close lying states corresponding to similar local 1Lb excitations on the two phenyls. We computed the corresponding vibronic ECD spectra in harmonic approximation, including Duschinsky mixings as well as both Franck Condon (FC) and Herzberg Teller (HT) effects. Exploiting a recently developed mixed quantum/classical method, we further investigated the contribution of the vibronic spectra of out-of-equilibrium structures along the interconversion path connecting the different conformers. In this way, we achieved a reasonable agreement with experiment and attributed the alternating signs of the bands to the existence of different conformers. The remaining discrepancies with experiment indicate that specific solute-solvent interactions modulate the relative conformers' stabilities, calling for new methods able to combine Molecular Dynamics explorations and vibronic calculations. Moreover, the poor performance of HT approaches and the existence of two closely-lying states suggest the necessity of an improved fully-nonadiabatic vibronic approach. These findings demonstrate that even for such a simple system as the biarylcarbinol investigated here, a full reproduction of the fine details of the ECD spectrum requires the development of new improved methods. PMID- 29184937 TI - Decreased domain size of p-DTS(FBTTh2)2/P(NDI2OD-T2) blend films due to their different solution aggregation behavior at different temperatures. AB - Nanoscale interpenetrating networks play a key role in determining the optoelectrical properties of functional blends. However, phase separated large domain sizes could probably be observed in pristine films composed of two crystalline components. For example, p-DTS(FBTTh2)2/P(NDI2OD-T2) 3/2 blend films with interpenetrating networks are obtained, however, large domain sizes are found when they are prepared from a 20 degrees C solution due to the simultaneous process of crystallization and phase separation during solvent evaporation. In this paper, we proposed to reduce the domain size of p DTS(FBTTh2)2/P(NDI2OD-T2) blend films using their different solution aggregation behaviors at different temperatures. The aggregation of p-DTS(FBTTh2)2 molecules in chlorobenzene (CB) was insensitive to the solution temperature. However, the in situ absorption spectra of the neat P(NDI2OD-T2) solution from 80 degrees C to room temperature indicated that P(NDI2OD-T2) aggregation increased with decreasing temperature due to intrachain interactions. Therefore, in order to reduce the domain size, we employed a hot solution to prepare the blend films. During the solidification process, the majority of p-DTS(FBTTh2)2 molecules were confined in the P(NDI2OD-T2) networks prior to occurrence of severe p DTS(FBTTh2)2 aggregation. Thus, the domain size of the p-DTS(FBTTh2)2 phase became smaller than that of the pristine films, leading to a decrease in the corresponding photoluminescence intensity of the blend films. In addition, the crystallinity of the blend films improved after thermal annealing, which resulted from the ordered alignment of p-DTS(FBTTh2)2 molecules facilitated by their enhanced diffusion ability. Based on the various morphologies, a possible phase diagram of the p-DTS(FBTTh2)2/P(NDI2OD-T2) blend system was depicted, which could be a guide to directly control the morphology of blend films. PMID- 29184939 TI - Consumption of plant food supplements in the Netherlands. AB - The use of food supplements containing herbs or other botanical ingredients (plant food supplements, PFS) is on the rise. In some cases, PFS can contain compounds that are toxic and may pose a health risk. To assess the potential health risks, information on the consumption of PFS is required, however, this was lacking for the Netherlands. In the current study, the consumption of PFS was investigated for several subgroups in the Dutch population, including children. Data from the Dutch National Food Consumption Surveys were used to get a first impression on the consumption of PFS. To obtain more detailed information, a specific PFS consumption survey was performed using online questionnaires. First, a screening survey was performed among a representative sample of 75 100 adults and children of the Dutch population, followed by a main survey among 739 selected PFS users in eight different age and gender subgroups. The prevalence of PFS users in the Dutch population was approximately 10% for men, 17% for women and 13% for children. A wide variety of PFS was used, with around 600 different PFS reported, containing 345 different botanicals. The most frequently used botanicals were echinacea (Echinacea purpurea), ginkgo (Ginkgo biloba), cranberry (Vaccinium macrocarpon), ginseng (Panax ginseng) and algae (such as species belonging to the genus Spirulina or Chlorella). Because PFS are widely used in the Dutch population, it is important to evaluate the potential risks associated with PFS consumption in the Netherlands, including potential herb-drug interactions. The data collected in this study are of great value to assess these risks. PMID- 29184938 TI - Minocycline hydrochloride loaded on titanium by graphene oxide: an excellent antibacterial platform with the synergistic effect of contact-killing and release killing. AB - Titanium and its alloys have been widely used in orthopedic and dental implants because of their excellent properties. However, implant failures still occur due to implant-associated bacterial infections. Therefore, proper surface modification of titanium and its alloys is necessary. In this work, commercial pure titanium plates were modified with graphene oxide (GO) which was used to load minocycline hydrochloride. Gram-positive Staphylococcus aureus (S. aureus) and Streptococcus mutans (S. mutans) and Gram-negative Escherichia coli (E. coli) were used to investigate the antibacterial activity of the samples. Human gingival fibroblast (HGF) cells were applied to assess the cytocompatibility of the various samples. To investigate cell adhesion and cell surface coverage in the presence of bacteria, the coculture of HGF cells and S. aureus was performed. The results indicated that the GO-modified titanium surface could inhibit the growth of the bacteria which had direct contact with GO, while it could not affect the bacteria without direct contact of GO. Minocycline hydrochloride on the GO-modified titanium surface (M@GO-Ti) showed a slow release behavior and exhibited excellent antibacterial activity with the synergistic effect of contact killing and release-killing by GO and minocycline hydrochloride, respectively. In the coculture process with the presence of S. aureus, HGF cells on M@GO-Ti demonstrated the best cell viability and cell surface coverage among all the samples.

AB - Two new coordination polymers, Cu(Hbsal)2(4,4'-bpy)2 (1) and Cu(bsal)(4,4' bpy).DMF (2), have been synthesized from 5-bromosalicylic acid (H2bsal) and the auxiliary ligand 4,4'-bipyridine (4,4'-bpy) through a slow diffusion method. Compound 1 is composed of parallel 1D linear chains, whereas compound 2 represents a non-interpenetrated 3D sod net which is constructed from left and right-handed helical chains alternately separated by 4,4'-bpy. The most interesting finding is that compound 1 can be irreversibly transformed into 2 in a crystal-to-crystal manner in the case that compound 1 is immersed in the DMF solvent. Particularly, the 1D-to-3D crystal-to-crystal structural transformation also incurs a drastic change in the magnetic properties of 1 and 2.

AB - Mononuclear complexes of stoichiometry [Ln(H3L)(H2O)(NO3)](NO3)2 (Ln = Tb, 1; Dy, 2, Er, 3), which crystallise with different solvates, and the heterotrinuclear compound [Zn2Dy(L)(NO3)3(OH)] (4) can be obtained with the same H3L compartmental ligand. The single X-ray crystal structure of the mononuclear complexes shows a LnO9 core with a muffin-like disposition while the geometry of the DyO9 core in 4 seems to be closer to spherical capped square antiprism. The analysis of the magnetic properties of all the complexes demonstrates that the mononuclear lanthanide compounds do not show slow relaxation of the magnetization, even when the samples are diluted with a diamagnetic matrix and subjected to a dc applied field of 1000 Oe. Nevertheless, the heterotrinuclear dysprosium complex 4.3H2O is a field-induced single ion magnet, with an estimated Ueff barrier of 59 K. The luminescence characterisation of all the metal complexes in methanol solution at 298 K also shows a notable increase in the fluorescence emission of the heterotrinuclear complex with respect to the mononuclear ones, in such a way that 4 can be defined as a fluorescent single ion magnet. PMID- 29184945 TI - Carbon adsorption on doped cementite surfaces for effective catalytic growth of diamond-like carbon: a first-principles study. AB - We studied the adsorption of carbon on (100), (010) and (001) surfaces of alloyed cementite (Fe2MC with M = Cr, Mn, Mo, Ni and V), in comparison with that of cementite (Fe3C), to predict the catalytic effect of the element-doped cementite on diamond-like carbon (DLC) growth through first-principles analysis. The adsorption of carbon on the alloyed cementite surface is related to its surface stability. The more stable a surface, the weaker its adsorption capability. Mn, Mo, Cr or V alloyed cementite have a higher adsorption energy than unalloyed cementite. A correlation has also been found between the adsorption and the transferred charge based on Bader charge analysis. Among all the types of doped cementite under study, Fe2NiC possesses the strongest catalytic activity for DLC growth based on the formation energy of diamond carbon. Doping cementite with the appropriate elements provides a promising means to improve the catalytic activity of Fe3C for effective DLC growth.

Various types of substrates are suitable for the reaction, including those with low reactivity, e.g. benzophenone. Among others, the protocol tolerates bromo-, cyano-, benzyloxy-, pyrimidyl and styryl moieties. PMID- 29184947 TI - A general strategy for the synthesis of indoloquinolizine alkaloids via a cyanide catalyzed imino-Stetter reaction. AB - A new strategy applicable to the synthesis of indoloquinolizine natural products has been developed. A cyanide-catalyzed intramolecular imino-Stetter reaction of aldimines, derived from 2-aminocinnamic acid derivatives and 2 pyridinecarboxaldehydes, provided indole-3-acetic acid derivatives bearing a pyridyl ring at the 2-position. Reduction of the carboxylic acid moiety to an alcohol followed by activation of the resulting alcohol with Tf2O or TsCl generated indoloquinolizinium salts, which were utilized as precursors for indoloquinolizine natural products. The advantage of this protocol was successfully demonstrated in the total syntheses of arborescidine A and nauclefidine.

AB - In recent years, great attention has been dedicated to the development of heterogeneous base catalysts providing a green and sustainable process in benign aqueous media. Herein, the ionic liquid modified layered double hydroxide (LDH) based catalysts of LDH-IL-Cn (n = 4, 8, 12) were prepared by adopting an exfoliation/assembly strategy, in which the ionic liquids (ILs) were covalently anchored onto the surface of LDH layers. The resulting LDH-IL-Cn were characterized by FT-IR, solid-state 13C NMR, 29Si CP/MAS NMR, 27Al-MAS NMR, XRD, TG-DTA, BET, XPS, SEM, CO2-TPD, contact angle experiments, etc. The catalytic performance of LDH-IL-C12 for the Knoevenagel condensation of a variety of aldehydes with ethyl cyanoacetate/malononitrile in H2O at room temperature showed excellent yields and selectivities. Moreover, the base catalyst of LDH-IL-C12 can be easily recycled and reused for at least 5 times without the decrease of its catalytic efficiency. The scaled-up experiments revealed that the catalyst retained its efficiency and robustness.

AB - A comprehensive first-principles study of the electronic properties of twisted 2D transition metal dichalcogenide (TMDC) heterobilayers MX2/MoS2 (M = Mo, Cr, W; X = S, Se) with different rotation angles has been performed. The van der Waals (vdW) interaction is found to have an important effect on the electronic structure of two-dimensional (2D) TMDC heterobilayers. Compared to non-twisted heterobilayers, the interlayer distance of twisted heterobilayers increases appreciably, thereby changing the vdW interaction of the heterobilayers as well as the electronic structure of the MX2/MoS2 systems. As a result, for CrSe2/MoS2 and MoSe2/MoS2 systems, the indirect bandgap (Gamma-K) exhibits a notable enlargement (about 0.1 eV), leading to the indirect-to-direct gap transition. At twisting angles between 13.2 degrees and 46.8 degrees , the interlayer distance is nearly constant for the mismatched lattices over the entire sample, resulting in nearly the same electronic structure. Even after considering the spin-orbit coupling (SOC) effect, the indirect-to-direct transition is still predicted to occur in the WS2/MoS2 heterobilayer due to the large spin-orbit splitting. PMID- 29184950 TI - Gold nanoparticle-based nano-probe for the colorimetric sensing of Cr3+ and Cr2O72- by the coordination strategy. AB - In this work, an N-T/gold nanoparticle system was assembled for the convenient and colorimetric identification of Cr based on its coordination chemistry with the thymine derivative (N-T). In addition to the visible colorimetric changes for the qualitative Cr identification, the A630 nm/520 nm values changed linearly with Cr concentration over a range of 0.5-2.5 MUM and the detection limits reached 0.03 MUM and 0.07 MUM for Cr3+ and Cr2O72-, respectively, both of which satisfied the Cr water quality standards of the U.S. EPA, WHO and China. Furthermore, a more convenient method was developed for quantitative determination of Cr concentrations in practical samples based on the Eyedropper function in Microsoft's PowerPoint software, wherein the RGB (red, green and blue) value of the sample could be easily screened in the colorimetric card for a more accurate result with good recovery, avoiding complicated instrumentation. PMID- 29184951 TI - Rattler-induced aging dynamics in jammed granular systems. AB - Granular materials jam when developing a network of contact forces able to resist the applied stresses. Through numerical simulations of the dynamics of the jamming process, we show that the jamming transition does not occur when the kinetic energy vanishes. Rather, as the system jams, the kinetic energy becomes dominated by rattler particles, which scatter within their cages. The relaxation of the kinetic energy in the jammed configuration exhibits a double power-law decay, which we interpret in terms of the interplay between backbone and rattler particles. PMID- 29184952 TI - Interfacial assembly and hydrolysis for synthesizing a TiO2/metal-organic framework composite. AB - Herein we propose an interfacial assembly and hydrolysis route for fabricating TiO2/UiO-67 composites. The UiO-67 assembles at the water-oil interface serving as a stabilizer of the emulsion. TiO2 nanoparticles are loaded on UiO-67 by hydrolysis of the precursor TBT (tetra-n-butyl titanate) at the water-oil interface. By such a strategy, hollow capsules structured by UiO-67 and decorated by ultra-small TiO2 nanoparticles were produced. The newly-constructed composite combines the CO2 adsorption properties of UiO-67 and the photocatalytic activity of TiO2, showing high activity for the photocatalytic reduction of CO2 to formic acid. Such a composite with a novel structure provides a promising route for the preparation of new compound materials. PMID- 29184953 TI - A one pot three-component reaction for the preparation of dihydroquinolines with two different ketones and aromatic amines. AB - A three component reaction with two different ketones and aromatic amines was firstly investigated. The difference in reactivity between ordinary ketones and ketone esters allowed for the production of 1,2-DHQs efficiently. The possible Skraup reaction with 2 equiv. of the same ketones was prohibited due to the fast formation of imines.

AB - Methyltransferases are powerful tools for site-specific transfer of non-natural functional groups from synthetic analogs of their cosubstrate S-adenosyl-l methionine (AdoMet). We present a new class of AdoMet analogs containing photo caging (PC) groups in their side chain, enzymatic transfer of PC groups by a promiscuous DNA MTase as well as light-triggered removal from the target DNA. This strategy provides a new avenue to reversibly modulate the functionality of DNA at MTase target sites. PMID- 29184955 TI - (+)- and (-)-Ascomlactone A: a pair of novel dimeric polyketides from a mangrove endophytic fungus Ascomycota sp. SK2YWS-L. AB - A pair of novel enantiomeric polyketide dimers, (+)- and (-)-ascomlactone A (1a and 1b), were obtained from a mangrove endophytic fungus Ascomycota sp. SK2YWS-L. The structures were elucidated based on spectroscopic methods, and the absolute configurations were determined by X-ray diffraction and electronic circular dichroism (ECD) calculations. Ascomlactone A possessed an unprecedented polymerization system, which constructed an unusual nine-membered lactone ring between the monomers. A possible biogenetic pathway was proposed. Both 1a and 1b exhibited significant inhibitory effects against alpha-glucosidase with IC50 values of 63.7 and 27.9 MUM, respectively. A further docking study provided an inside perspective of the action in alpha-glucosidase. PMID- 29184956 TI - Influence of imide-substituents on the H-type aggregates of perylene diimides bearing cetyloxy side-chains at bay positions. AB - A series of perylene-3,4:9,10-tetracarboxylic acid diimides (PDIs, namely TYR PDI, AEP-PDI, CET-PDI, ANP-PDI and KOD-PDI), comprising long linear cetyloxy side chains functionalized at the 1,7-bay positions and the different substituents (i.e., hydrophobic/hydrophilic segments) symmetrically linked at the two imide positions of the perylene core were synthesized to investigate the influence of imide-substituent patterns on the aggregation behaviours of PDIs. The photophysical properties of these PDIs were studied by UV-Vis absorption, fluorescence and time-resolved photoluminescence spectroscopy. The differences in the photophysical properties of the PDIs indicate (i) blue-shifted and broadening absorption properties in both solution and thin-films, (ii) red-shifted and broadening fluorescence behavior at their emission maximum in solution, however, blue-shifted fluorescence behavior in thin-films, and (iii) obviously longer fluorescence life-times corresponding to the existence of rotationally displaced H-type aggregates. The formation of short-range ordered rod-like microstructures through face-to-face alignment of columnar rectangular H-type PDI aggregates was rationalized by scanning electron microscopy. The X-ray diffraction study revealed that the formation of well-defined columnar rectangular (Colrp) H-type PDI aggregates indicated a nearly constant intracolumnar stacking distance of ~3.9 A for all PDIs. All of these findings were consistent with the formation of hydrophobic/hydrophilic interactions between the imide-substituents in addition to the strong hydrophobic pi-pi stacking interactions between the conjugated perylene cores, which were enforced in the H-type PDI aggregates that spontaneously self-organized into Colrp structures. PMID- 29184957 TI - Liposomal internal viscosity affects the fate of membrane deformation induced by hypertonic treatment. AB - Artificial lipid membranes have been utilized to understand the physical mechanisms of the deformation patterns of live cells. However, typical artificial membrane systems contain only dilute components compared to those in the cytoplasm of live cells. By using giant unilamellar liposomes containing dense protein solutions similar to those in live cells, we here reveal that viscosity derived from internal crowding affects the deformation patterns of lipid membranes. After hypertonic treatment, liposome deformation patterns transitioned from budding to tubing when the initial internal macromolecular concentrations were increased. Remarkably, instead of observing different transition concentrations between two species of macromolecules, the viscosity at the transition concentration was found to be similar. Further analyses clearly demonstrated that the internal viscosity affects the deformation patterns of lipid membranes induced by hypertonic treatment. These results indicate that the viscosity of the cytoplasm is a key factor in determining cell deformation, and suggest the association of a process involving dynamic instability, such as a viscous fingering phenomenon, during the determination of deformation patterns by hypertonic treatment. PMID- 29184958 TI - Hydration peculiarities of graphene oxides with multiple oxidation degrees. AB - Hydration properties of graphene oxide (GO) are essential for most of its potential applications. In this work, we employ atomistic molecular dynamics simulations to investigate seven GO compositions with different levels of oxygenation. Two atomic charge models for GO are compared: (1, a simplified model) sp2 carbons are purely Lennard-Jones sites; (2, a CHELPG model) sp2 carbon charges are consistent with the CHELPG scheme. Structural properties were found to depend insignificantly on the charge model, whereas thermodynamics appeared very sensitive. In particular, the simplified model provides systematically stronger GO/water coupling, as compared to the more accurate model. For all GO compositions, hydration free energies are in the range of -5 to -45 kJ mol-1 indicating that hydration is thermodynamically favourable even for modest oxidation degrees, thus differing drastically from the cases of pristine graphene and graphite. In general, it has been observed that as R increases the high oxidation degree obstructs the formation of new hydrogen bonds, which considerably affects their hydration properties. Although both the used charge models are qualitatively equivalent, the energy and number of hydrogen bonds have been shown to be sensitive to the charge set employed. In particular, the comparison shows that the simplified model tends to overestimate the GO/water interaction energy. The results and discussion presented herein provide a physical background for modern applications of GO, e.g. in electrodes of supercapacitors and inhibitors in processes involving biological molecules.

AB - This paper reports a multi-throughput multi-organ-on-a-chip system formed on a pneumatic pressure-driven medium circulation platform with a microplate-sized format as a novel type of microphysiological system. The pneumatic pressure driven platform enabled parallelized multi-organ experiments (i.e. simultaneous operation of multiple multi-organ culture units) and pipette-friendly liquid handling for various conventional cell culture experiments, including cell seeding, medium change, live/dead staining, cell growth analysis, gene expression analysis of collected cells, and liquid chromatography-mass spectrometry analysis of chemical compounds in the culture medium. An eight-throughput two-organ system and a four-throughput four-organ system were constructed on a common platform, with different microfluidic plates. The two-organ system, composed of liver and cancer models, was used to demonstrate the effect of an anticancer prodrug, capecitabine (CAP), whose metabolite 5-fluorouracil (5-FU) after metabolism by HepaRG hepatic cells inhibited the proliferation of HCT-116 cancer cells. The four-organ system, composed of intestine, liver, cancer, and connective tissue models, was used to demonstrate evaluation of the effects of 5-FU and two prodrugs of 5-FU (CAP and tegafur) on multiple organ models, including cancer and connective tissue. PMID- 29184960 TI - Damage-free and rapid transfer of CVD-grown two-dimensional transition metal dichalcogenides by dissolving sacrificial water-soluble layers. AB - As one of the most important family members of two-dimensional (2D) materials, the growth and damage-free transfer of transition metal dichalcogenides (TMDs) play crucial roles in their future applications. Here, we report a damage-free and highly efficient approach to transfer single and few-layer 2D TMDs to arbitrary substrates by dissolving a sacrificial water-soluble layer, which is formed underneath 2D TMD flakes simultaneously during the growth process. It is demonstrated, for monolayer MoS2, that no quality degradation is found after the transfer by performing transmission electron microscopy, Raman spectroscopy, photoluminescence and electrical transport studies. The field effect mobility of the post-transfer MoS2 flakes was found to be improved by 2-3 orders compared with that of the as-grown ones. This approach was also demonstrated to be applicable to other TMDs, other halide salts as precursors, or other growth substrates, indicating its universality for other 2D materials. Our work may pave the way for material synthesis of future integrated electronic and optoelectronic devices based on 2D TMD materials. PMID- 29184961 TI - Highly sensitive detection of hesperidin using AuNPs/rGO modified glassy carbon electrode. AB - The highly sensitive and selective electrochemical sensor of hesperidin based on gold nanoparticles (AuNPs) and reduced graphene oxide (rGO) modified glassy carbon electrode (GCE) is reported. The AuNPs and rGO were uniformly introduced on the surface of the GCE via electrodeposition without any reducing agents and have been characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDX), X-ray photoelectron spectroscopy (XPS), FT-IR, and electrochemical methods. The AuNPs/rGO not only promoted the accumulation of hesperidin onto the GCE surface for quantitative analysis but also accelerated the electron transfer between hesperidin and the electrode substrates. Under the optimal conditions, hesperidin was determined quantitatively at the AuNPs/rGO/GCE using amperometric i-t curve. The results showed that the current obtained on detection of hesperidin exhibited a linear correlation with its concentration in the range of 5.0 * 10-8 mol L-1-8.0 * 10-6 mol L-1 with a detection limit of 8.2 * 10-9 mol L-1 (S/N = 3). In addition, good specificity, repeatability, reproducibility, and long-term storage stability were achieved for the modified electrode, which could be used for the detection of hesperidin in the traditional Chinese medicine, Pericarpium Citri Reticulatae. PMID- 29184962 TI - One dimensional building blocks for molecular separation: laminated graphitic nanoribbons. AB - Herein, a new carbon-based graphitic membrane composed of laminated graphitic nanoribbons with a nanometer-scale width and micrometer-scale length, the graphitic nanoribbon membrane, is reported. Compared to the existing graphitic membranes, such as those composed of graphene oxide and carbon nanotubes, the developed membrane exhibits several unique characteristics in pressure-driven systems. First, the short diffusion length through its interlayer and the free volume of its stacked nanoribbons result in high solvent flux regardless of solvent polarity (water: 25-250 L m-2 h-1 bar-1; toluene: ~975 L m-2 h-1 bar-1; hexane: ~240 L m-2 h-1 bar-1). The flux value for water is one order of magnitude higher, while that for nonpolar organic solvents is two to three orders of magnitude greater than the corresponding flux values obtained through commercially available nanofiltration membranes. Second, the membrane exhibits good separation performance, particularly with organic dye molecules (~100%) and trivalent ions (~60%), maintaining high solvent flux during extended filtration. Finally, the membrane exhibits high stability in various fluids, e.g., 1 M HCl solution, 1 M NaOH solution, toluene, ethanol, and water, as well as under hydraulic pressures of up to 50 bar. Electron microscopy observation and simulation results suggest that such distinctive features of the membrane are related to the entangled thin multilayers of the graphitic nanoribbons, which possibly originate from the high aspect ratio and narrow width of the nanoribbons. PMID- 29184963 TI - Slow or fast viral load decay as a predictor of residual viremia level in HIV infected patients undergoing successful first-line cART. AB - Persistent residual viremia (RV) has been demonstrated in 70-90% of patients under successful cART. We analyzed the RV trend during the first year following cART-induced virological suppression (VS; HIVRNA <50 copies/ml) to identify predictors of achievement and maintenance of ultra-deep RV suppression (URVS; HIV RNA <5 copies/ml) in 60 naive patients. These patients were aligned at the time of reaching VS and were longitudinally tested with an ultrasensitive HIV-RNA assay. The influence of demographics, primary/chronic infection, pre-therapy HIV RNA and CD4, cART regimen and time to reach VS on RV trends was evaluated. During the first year following VS, median RV levels steadily decreased. RV dropped below 5 copies/ml at least once in each patient, but URVS was maintained in 45% of patients. RV rebounded to levels fluctuating around 5-10 copies/ml while in the remaining 55% of patients. Predictors of early achievement and maintenance of stable URVS were fast (<12 weeks) VS achievement after the start of therapy, better pre-treatment viro-immunological conditions (lower viremia and higher CD4 before cART), and treatment initiation during primary infection. These findings emphasize the importance of an early onset of potent antiretroviral regimens. RV trends should be further studied in detail in the following years of cART. PMID- 29184964 TI - Development of an EliSPOT assay for HSV-1 and clinical validation in lung transplant patients. AB - Cellular immunity plays a major role in the control of HSV-1 infection/reactivation with a potential impact on the clinical-therapeutic management of immunocompromised patients, such as transplant recipients. Herein, we quantitatively evaluated T-cell response directed at HSV-1 by a newly developed IFN-gamma EliSPOT assay in 53 patients (including 45 lung transplant recipients and eight subjects in waiting list). Overall, 62.2% of transplant patients and 62.5% of subjects on the waiting list showed a response to HSV-1 with no significant difference in the level of virus-specific cellular immunity. Response tended to be lower in the first three months posttransplantation with a progressive recovery of pretransplantation status by the second year and in the presence of HSV-1 DNA positivity in bronchoalveolar lavage. As expected, no response was found in seronegative patients. No significant difference in the level of response according to IgM and IgG status was found. Further studies are required to define the role of HSV-1 specific immune response for the clinical therapeutic management of lung transplant patients and in other clinical settings and to define cut-off levels discriminating between absence/low and strong response to be related to the risk of viral infection/reactivation. PMID- 29184965 TI - Is self-reported time spent sedentary and in physical activity differentially biased by age, gender, body mass index, and low-back pain? AB - Objectives This study aimed to determine the extent to which age, gender, body mass index (BMI) and low-back pain (LBP) influence bias in self-reported sedentary behavior and moderate-to-vigorous physical activity (MVPA) among blue collar workers. Methods For 2-4 consecutive working days, 147 workers wore an Actigraph accelerometer on the thigh. Proportional time spent sedentary and in MVPA was determined using the Acti4 software. The same variables were also self reported in a questionnaire. The difference between self-reported and accelerometer-based sedentary time and MVPA was calculated and linearly regressed against age, gender, BMI, and self-reported LBP intensity as main effects, as well as interaction terms combining each of these factors with objectively measured exposure. Results Workers objectively spent 64% of their time sedentary and 9% in MVPA. On average, self-reports underestimated sedentary time by 1.5% and overestimated MVPA by 5.5%. Workers with mild/no LBP appeared to have the same size of self-report bias in MVPA regardless of how much MVPA they actually had, while workers with high LBP overestimated MVPA to an increasing extent with increasing exposure [interaction: B=0.29, 95% confidence interval (CI) 0.05 0.53]. Age was positively associated with self-report bias in sedentary time (B=0.31, 95% CI 0.09-0.54) regardless of actual sedentary time. Conclusions LBP and age, but not BMI and gender, introduced differential bias in self-reported information on sedentary behavior and MVPA among blue-collar workers. This result suggests that bias correction in future studies based on self-reports of sedentary time and MVPA should account for LBP and age. PMID- 29184966 TI - Recommendations to improve the EU non-technical summaries of animal experiments. AB - Under the new Directive 2010/63/EC, member states have to publish non-technical summaries (NTS) of the projects involving animals that they authorise. These summaries must include information on the objectives of the project including the predicted harm and benefits and the number and types of animals to be used. Summaries should also demonstrate compliance with the 3Rs. The intention was that NTS would help increase the transparency of animal research in the EU. In this article, we review the status of the publication of NTS across member states and give some general observations on publication speed, identification, accessibility and quality. We also review in more detail the quality of reporting in a selection of NTS from Germany and the UK. We consistently found that NTS from Germany and the UK were deficient in their description of what is being done to the animals and what they might experience as a result. Using examples taken from specific NTS we highlight what we view to be good and bad examples to assist member states and researchers in producing better NTS in the future. The NTS can also be an important tool in sharing of best practice in the 3Rs and the avoidance of duplicative animal testing. For this to happen however, member states need to publish timely, ensure that NTS are accurate and, ideally, there needs to be some centralisation of the NTS.

PMID- 29184968 TI - Hippocratic method for reduction of chronic locked anterior shoulder dislocations. AB - PURPOSE: Old shoulder dislocations are usually treated by a variety of surgical approaches. Closed reduction of chronic unreduced dislocation is less widely reported. This study was to evaluate the outcome of reduction of old anterior shoulder dislocations using the Hippocratic method. METHODS: Between January 2008 and July 2016, patients with unilateral old shoulder dislocations included 10 women and three men with an average age of 60.00 +/- 2.83 years. Eight dislocations involved the right shoulder and five the left shoulder. The average delay between dislocation and treatment was 4.46 +/- 0.97 weeks (ranging from 3 weeks to 6 weeks). One case also had a greater tuberosity fracture. No patients had distal nerve or artery dysfunction. The patients were all healthy prior to dislocation, i.e., no diabetes, hypertension, or heart disease, etc. Dislocations were diagnosed according to anteroposterior shoulder X-rays. Shoulder function was assessed using the Constant-Murley score. All manual reductions were conducted under general anesthesia using the Hippocratic method. RESULTS: All shoulder dislocations were successfully reduced with the Hippocratic method. The mean time of closed reduction was 31.46 +/- 7.60 min and the mean hospitalization time was 2.77 +/- 1.09 days. No neurovascular injury or humerus fractures were noted during hospitalization. The Constant-Murley scores before reduction and after reduction were 34.31 +/- 7.25 and 60.92 +/- 8.95, respectively. These scores were significantly higher after reduction compared with before reduction (P < 0.01). No recurrent dislocation was observed in any patients during the follow-up period. CONCLUSION: The closed reduction of old anterior shoulder dislocations using the Hippocratic method is not unfeasible and should be attempted in selected patients. PMID- 29184969 TI - Out-of-pocket health expenditures in patients with bipolar disorder, anxiety, schizophrenia and other psychotic disorders: findings from a study in a psychiatry outpatient clinic in Turkey. AB - PURPOSE: The aim of this study is to explore the amount of OOP health expenditures and their determinants in patients with bipolar disorder, anxiety, schizophrenia and other psychotic disorders in a psychiatry outpatient clinic of Turkey. METHODS: The study group was 191 patients who attended to the Psychiatry Outpatient Clinic in June 2014. All patients were previously diagnosed with either 'bipolar disorder', 'anxiety disorder' or 'schizophrenia and other psychotic disorders'. The dependent variable was OOP expenditures for prescription, medical tests and examinations. Independent variables were age, gender, education, occupation, existence of social and/or private health insurance, equivalent household income and the financial resources. Student's t test, Mann-Whitney U test, ANOVA and logistic regression methods were applied with SPSS 15.0 for analysis. RESULTS: OOP expenditures per admission were higher in patients with schizophrenia and other psychotic disorders ($8.4) than those with anxiety disorders ($4.8) (p = 0.02). OOP expenditures were higher in patients paying with debit ($9.8) than paying with monthly income ($6.2) (p = 0.04). OOP expenditures were higher in patients without social health insurance ($45.8) than others ($4.8) (p = 0.003). There was not a difference in OOP expenditures with respect to equivalent household income level, occupational class or education level of the patients (respectively p: 0.90, p: 0.09, p: 0.52). CONCLUSIONS: Patients who were diagnosed with 'schizophrenia and other psychotic disorders' were disadvantaged in paying significantly higher amounts for their treatment. A substantial group of these patients compulsorily payed with debit. Considering this financial burden, diagnosis of the patient should be prioritized in health insurance coverage.

AB - Early studies of transcriptional regulation focused on individual gene promoters defined specific transcription factors as central agents of genetic control. However, recent genome-wide data propelled a different view by linking spatially organized gene expression patterns to chromosomal dynamics. Therefore, the major problem in contemporary molecular genetics concerned with transcriptional gene regulation is to establish a unifying model that reconciles these two views. This problem, situated at the interface of polymer physics and network theory, requires development of an integrative methodology. In this review, we discuss recent achievements in classical model organism E. coli and provide some novel insights gained from studies of a bacterial plant pathogen, D. dadantii. We consider DNA topology and the basal transcription machinery as key actors of regulation, in which activation of functionally relevant genes is coupled to and coordinated with the establishment of extended chromosomal domains of coherent transcription. We argue that the spatial organization of genome plays a fundamental role in its own regulation. PMID- 29184973 TI - Variability of T1-weighted signal intensity of pericallosal lipomas in the fetus. AB - BACKGROUND: Pericallosal lipomas are often associated with corpus callosum dysgenesis. The diagnosis of lipoma, suggested on ultrasonography, relies on the classic T1 hyperintensity on magnetic resonance imaging (MRI). However, this feature may be absent prenatally. OBJECTIVE: Our objective was to study the changes of T1 intensity in fetal lipomas with comparison to postnatal/postmortem data and to assess the factors influencing the signal variations of pericallosal lipomas on prenatal MRI. MATERIALS AND METHODS: Patients with callosum dysgenesis and interhemispheric hyperechogenicity suggestive of a pericallosal lipoma with available postnatal or postmortem data were included. Gestational age, lipoma size and pattern, corpus callosum size and changes in fetal fat T1 intensity were recorded. Comparison with postmortem neuropathology was available for one fetus. RESULTS: Eleven patients with callosum dysgenesis and pericallosal lipomas (seven curvilinear and four tubulonodular) were included. All MRI scans were performed in the third trimester. Curvilinear lipomas were thinner and six cases were associated with prenatal T1 iso-intensity. Typical T1 hyperintensity appeared on postnatal MRI only. All tubulonodular lipomas were much larger and showed prenatal T1 hyperintensity. In two patients, the lipoma increased in size on postnatal MRI. CONCLUSION: The type and size of a lipoma influence T1 prenatal intensity. Absence of T1 intensity was observed in curvilinear lipomas only. Curvilinear lipomas are much thinner. Changes in T1 intensity may also be related to fat maturation within the lipoma and, subsequently, to gestational age. In the case of callosum dysgenesis, absence of prenatal T1 pericallosal hyperintensity should not exclude the diagnosis of pericallosal lipoma.

AB - Targeting of the protein degradation pathway, in particular, the ubiquitin proteasome system, has emerged as an attractive novel cancer chemotherapeutic modality. Although proteasome inhibitors have been most successfully applied in the treatment of hematological malignancies, they also received continuing interest for the treatment of solid tumors. In this review, we summarize the current positioning of proteasome inhibitors in the treatment of common solid malignancies (e.g., lung, colon, pancreas, breast, and head and neck cancer), addressing topics of their mechanism(s) of action, predictive factors and molecular mechanisms of resistance. PMID- 29184974 TI - Virus-induced apoptosis and phosphorylation form of metacaspase in the marine coccolithophorid Emiliania huxleyi. AB - Lytic viral infection and programmed cell death (PCD) are thought to represent two distinct death mechanisms in phytoplankton, unicellular photoautotrophs that drift with ocean currents. PCD (apoptosis) is mainly brought about by the activation of caspases, a protease family with unique substrate selectivity. Here, we demonstrated that virus infection induced apoptosis of marine coccolithophorid Emiliania huxleyi BOF92 involving activation of metacaspase. E. huxleyi cells exhibited cell death process akin to that of apoptosis when exposed to virus infection. We observed typical hallmarks of apoptosis including cell shrinkage, associated nuclear morphological changes and DNA fragmentation. Immunoblotting revealed that antibody against human active-caspase-3 shared epitopes with a protein of ~ 23 kDa; whose pattern of expression correlated with the onset of cell death. Moreover, analysis on two-dimensional gel electrophoresis revealed that two spots of active caspase-3 co-migrated with the different isoelectric points. Phosphatase treatment of cytosolic extracts containing active caspases-3 showed a mobility shift, suggesting that phosphorylated form of this enzyme might be present in the extracts. Computational prediction of phosphorylation sites based on the amino acid sequence of E. huxleyi metacaspase showed multiple phosphorylated sites for serine, threonine and tyrosine residues. This is the first report showing that phosphorylation modification of metacaspase in E. huxleyi might be required for certain biochemical and morphological changes during virus induced apoptosis.

AB - A novel Gram-staining positive, moderately halophilic, endospore-forming, motile, rod-shaped and strictly aerobic strain, designated YIM 93565T, was isolated from a salt lake in Xinjiang province of China and subjected to a polyphasic taxonomic study. Strain YIM 93565T grew in the range of pH 6.0-9.0 (optimum pH 7.0), 10-45 degrees C (optimum 35-40 degrees C) and at salinities of 2-24% (w/v) NaCl (optimum 7-10%). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YIM 93565T clustered with members of the genera Gracilibacillus and form a clade with Gracilibacillus bigeumensis KCTC 13130T (95.6% similarity) and Gracilibacillus halophilus DSM 17856T (94.9%), which was well separated from others. The DNA G + C content of this novel strain was 36.8 mol%. The major fatty acids were anteiso-C15:0, iso-C15:0, C16:0 and anteiso-C17:0 and its polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, one unidentified glycolipid and two unidentified phospholipids. The predominant menaquinone was MK 7. The cell-wall peptidoglycan was based on meso-diaminopimelic acid. Based on the results of phylogenetic, physiological and chemotaxonomic comparative analyses, the isolate is assigned to a novel species of the genus Gracilibacillus, for which the name Gracilibacillus eburneus sp. nov. is proposed, with the type strain YIM 93565T (= DSM 23710T = CCTCC AB 2013249T).

AB - Little is known of how soil archaeal community composition and diversity differ between local variants of tropical rainforests. We hypothesized that (1) as with plants, animals, fungi, and bacteria, the soil archaeal community would differ between different variants of tropical forest; (2) that spatially rarer forest variants would have a less diverse archaeal community than common ones; (3) that a history of forest disturbance would decrease archaeal alpha- and beta diversity; and (4) that archaeal distributions within the forest would be governed more by deterministic than stochastic factors. We sampled soil across several different forest types within Brunei, Northwest Borneo. Soil DNA was extracted, and the 16S rRNA gene of archaea was sequenced using Illumina MiSeq. We found that (1) as hypothesized, there are distinct archaeal communities for each forest type, and community composition significantly correlates with soil parameters including pH, organic matter, and available phosphorous. (2) As hypothesized, the "rare" white sand forest variants kerangas and inland heath had lower archaeal diversity. A nestedness analysis showed that archaeal community in inland heath and kerangas was mainly a less diverse subset of that in dipterocarp forests. However, primary dipterocarp forest had the lowest beta-diversity among the other tropical forest types. (3) Also, as predicted, forest disturbance resulted in lower archaeal alpha-diversity-but increased beta-diversity in contrast with our predictions. (4) Contrary to our predictions, the BetaNTI of the various primary forest types indicated community assembly was mainly stochastic. The possible effects of these habitat and disturbance-related effects on N cycling should be investigated.

PMID- 29184978 TI - Chronic infection and infected non-union of the long bones in paediatric patients: preliminary results of bone versus beta-tricalcium phosphate grafting after induced membrane formation. AB - PURPOSE: Chronic infection (CO) and infected non-union of the long bones are relatively rare conditions in paediatric patients. Large bone defects secondary to these conditions can be managed with the induced membrane technique. The technique requires grafting of the bone void, although it is not yet established what bone substitute is the best option. The aim of this work was to evaluate the outcome and efficacy of treatment in children with CO and infected non-union of the long bones using the induced membrane technique and bone (BG) versus beta tricalcium phosphate (BTP) grafting. METHODS: Eight skeletally immature patients with CO and infected non-union of the long bones were treated surgically between 2010 and 2017 by a combination of resection of necrotic infected bone, debridement of surrounding soft tissue, osteosynthesis using a stable internal fixation when needed, and application of antibiotic-laden cement (ALC) spacer inducing new membrane before final bone reconstruction with bone substitutes: BTP in five cases, BG (allograft and/or autologous graft) in three cases. A second surgical step, once inflammatory markers had normalized, consisted of ALC spacer removal, application of BG or BTP graft and concomitant stable osteosynthesis, if needed, if this had not been done during the first surgical stage. All the patients underwent clinical, laboratory and imaging evaluation before and after surgery. Antibiotics were adjusted according to culture and sensitivity. RESULTS: Mean patient age at time of diagnosis was 13 +/- four years (range, 4-16) and all had at least a 12-month follow-up (range 12-60). Estimated time for induced membrane formation was significantly shorter in patients treated with BTP compared with BG: 3+/-1 vs. 10+/-2 (p = 0.02). This result was confirmed by multivariate analysis (p = 0.044) taking into account adjustment for age of patients and time after initial surgery. Time of final union was about 5.5 +/- 4.1 months (range 2-66). At the last follow-up visit, bone had healed and all the patients had resumed daily living and sports activities. CONCLUSION: The induced membrane technique with BG or BTP graft can achieve bone healing in large bone defects secondary to CO and infected non-union in children and adolescents. The choice of bone substitute is important. Our preliminary results show graft integration and bone healing can be expected sooner if BTP is used as bone void filler. PMID- 29184979 TI - Right Ventricular Longitudinal Shortening Before and After Stage I Surgical Palliation Correlates with Outcomes. AB - Quantification of right ventricular function is difficult, but important, in patients with single ventricles. Tissue motion annular displacement (TMAD) is an echocardiographic tool that measures displacement of the tricuspid valve relative to the apex. We evaluated TMAD, lateral annular displacement (LAD), and fractional area change (FAC) for correlation with outcomes. We measured TMAD, LAD, FAC, and other variables that may affect prognosis in patients with single right ventricle physiology pre- and post-Stage I palliation and correlated them with outcomes up to the Glenn procedure. Intra- and inter-observer variability for TMAD measurements were 2.7% (1.2-3.5%) and 6.1% (3.3-8.1%), respectively. Sixty-six subjects met the inclusion criteria. Pre-Stage I TMAD was 13.7% (SD 3.9%). TMAD had a linear relationship with FAC (r2 = 0.76). There was a correlation between TMAD and hospital stay (p = 0.044) and ECMO/arrest (p = 0.024). LAD correlated with ECMO/arrest (p = 0.045) and mortality/transplant (p = 0.049). FAC correlated with in-hospital mortality (p = 0.028). Post-Stage I TMAD was 11.8% (SD 3.7%). TMAD, LAD, and FAC all correlated with in-hospital mortality and mortality/transplant. In multivariate models, TMAD was independently predictive of weight for age Z score pre-Glenn. TMAD, FAC, and LAD correlate with clinically significant outcomes after the first-stage palliation. TMAD correlated with more outcomes than FAC and was the only measure that was independently predictive of any outcome. TMAD is a reproducible measure of RV function in this population. TMAD has prognostic value before and after first-stage palliation and may outperform more traditional measures. PMID- 29184980 TI - Blockage of the NLRP3 inflammasome by MCC950 improves anti-tumor immune responses in head and neck squamous cell carcinoma. AB - The NLRP3 inflammasome is a critical innate immune pathway responsible for producing active interleukin (IL)-1beta, which is associated with tumor development and immunity. However, the mechanisms regulating the inflammatory microenvironment, tumorigenesis and tumor immunity are unclear. Herein, we show that the NLRP3 inflammasome was over-expressed in human HNSCC tissues and that the IL-1beta concentration was increased in the peripheral blood of HNSCC patients. Additionally, elevated NLRP3 inflammasome levels were detected in tumor tissues of Tgfbr1/Pten 2cKO HNSCC mice, and elevated IL-1beta levels were detected in the peripheral blood serum, spleen, draining lymph nodes and tumor tissues. Blocking NLRP3 inflammasome activation using MCC950 remarkably reduced IL-1beta production in an HNSCC mouse model and reduced the numbers of myeloid derived suppressor cells (MDSCs), regulatory T cells (Tregs) and tumor-associated macrophages (TAMs). Moreover, inhibiting NLRP3 inflammasome activation increased the numbers of CD4+ and CD8+ T cells in HNSCC mice. Notably, the numbers of exhausted PD-1+ and Tim3+ T cells were significantly reduced. A human HNSCC tissue microarray showed that NLRP3 inflammasome expression was correlated with the expression of CD8 and CD4, the Treg marker Foxp3, the MDSC markers CD11b and CD33, and the TAM markers CD68 and CD163, PD-1 and Tim3. Overall, our results demonstrate that the NLRP3 inflammasome/IL-1beta pathway promotes tumorigenesis in HNSCC and inactivation of this pathway delays tumor growth, accompanied by decreased immunosuppressive cell accumulation and an increased number of effector T cells. Thus, inhibition of the tumor microenvironment through the NLRP3 inflammasome/IL-1beta pathway may provide a novel approach for HNSCC therapy. PMID- 29184981 TI - The TET enzymes. AB - During the past decade, we have learnt that the most common DNA modification, 5 methylcytosine (5mC), playing crucial roles in development and disease, is not stable but can be actively reversed to its unmodified form via enzymatic catalysis involving the TET enzymes. These ground-breaking discoveries have been achieved thanks to technological advances in the detection of the oxidized forms of 5mC and to the boldness of individual scientists. The TET enzymes require molecular oxygen for their catalysis, making them important targets for hypoxia research. They also require special cofactors which enable additional levels of regulation. Moreover, mutations and other genetic alterations in TETs are found, especially in myeloid malignances. This review focuses on the kinetic and inhibitory properties of the TET enzymes and the role of TETs in cellular differentiation and transformation and in cancer.

AB - BACKGROUND: If compression bandaging is not performed in a professional manner, the objectives of the therapy may not be achieved and side effects or complications may result. OBJECTIVES: This cross-sectional observational survey examines the handling of the treatment options: short-stretch bandages with padding, multicomponent compression systems, and adaptive compression bandages. PARTICIPANTS AND METHODS: During several training sessions on the topic of compression therapy, 137 participants performed compression bandagings on each other. In this regard, they were asked to achieve a predetermined pressure range (short-stretch bandages: 50-60 mm Hg, multicomponent compression systems: 40-50 mm Hg, adaptive compression bandage: 35-45 mm Hg). To evaluate the efficiency, the time used for application, the achieved pressure value, and the comfort were determined. RESULTS: Of the 302 bandagings (n = 137 participants), 28.4% lay within the given target pressure value range. This included 11.2% of performed short-stretch bandages, 35.2% of multicomponent compression systems, and 85.0% of adaptive compression bandages. Significant differences in the mean deviations are found between the treatment options. The bandage was described as being comfortable by 37.7% of users of short-stretch bandages with padding, by 65.0% of those wearing a multicomponent compression system, and by 94.6% of participants with an adaptive compression bandage. CONCLUSIONS: In practice, short-stretch bandages are still the most frequently used care option for the creation of a phlebological compression bandage. In this survey, they proved to be unsafe, time consuming, and uncomfortable in relation to other treatment options. Multicomponent compression systems and adaptive compression bandages are treatment options that may be a contemporary alternative which also bares more comfort for the patient. PMID- 29184984 TI - [Charcot foot masked by erysipelas and peripheral arterial disease]. AB - Charcot foot is also known as Charcot disease or Charcot arthropathy. The associated aseptic destruction of the bones and joints of the foot results due to peripheral neuropathy accompanied by impaired pain perception, impaired vasomotricity with increased vasodilation, and an unequal weight distribution. Because it is frequently diagnosed late and, thus, incorrectly treated, serious complications often result. An 86-year-old man in poor health was diagnosed with erysipelas of the right foot. The foot was glossy and edematously swollen, showing necrosis of the distal phalanx of the third toe. The patient experienced pain after a walking distance of approximately 20 m. In addition to erysipelas, confirmed neuropathic arthropathy and radiological indicators for Charcot foot established peripheral artery disease (PAD) as a third diagnosis. Despite multiple systemic antibiotic therapies, there was a progressive disease pattern marked by increasing inflammation parameters with an increasing decline of the patient's overall health. The patient suffered severe deterioration in spite of vascular surgical measures, ultimately leading to his death. In the present case, the indicators and respective confirmation of the three overlapping diagnoses erysipelas, Charcot foot and PAD are elaborated. PMID- 29184982 TI - D2A sequence of the urokinase receptor induces cell growth through alphavbeta3 integrin and EGFR. AB - The urokinase receptor (uPAR) stimulates cell proliferation by forming a macromolecular complex with alphavbeta3 integrin and the epidermal growth factor receptor (EGFR, ErbB1 or HER1) that we name the uPAR proliferasome. uPAR transactivates EGFR, which in turn mediates uPAR-initiated mitogenic signal to the cell. EGFR activation and EGFR-dependent cell growth are blocked in the absence of uPAR expression or when uPAR activity is inhibited by antibodies against either uPAR or EGFR. The mitogenic sequence of uPAR corresponds to the D2A motif present in domain 2. NMR analysis revealed that D2A synthetic peptide has a particular three-dimensional structure, which is atypical for short peptides. D2A peptide is as effective as EGF in promoting EGFR phosphorylation and cell proliferation that were inhibited by AG1478, a specific inhibitor of the tyrosine kinase activity of EGFR. Both D2A and EGF failed to induce proliferation of NR6-EGFR-K721A cells expressing a kinase-defective mutant of EGFR. Moreover, D2A peptide and EGF phosphorylate ERK demonstrating the involvement of the MAP kinase signalling pathway. Altogether, this study reveals the importance of sequence D2A of uPAR, and the interdependence of uPAR and EGFR. PMID- 29184985 TI - [Quality of self-applied compression bandages in patients with chronic venous ulcers : Results of a prospective clinical study]. AB - BACKGROUND: For effective compression therapy in patients with venous leg ulcers, sufficient pressure is essential. In everyday life, it is often the patients themselves who apply the compression bandages. Many of these patients have restriction in their movement and had been rarely trained adequately. Hence, there was the question of how efficient are the autonomously applied compression bandages of those patients. PATIENTS AND METHODS: In all, 100 consecutive patients with venous leg ulcer were asked to apply compression bandages on their own leg. We documented both the achieved compression and formal criteria of correct performance. RESULTS: A total of 59 women and 41 men with an average age of 70.3 years were included in the study. Overall 43 patients were not able to apply a compression bandage because of physical limitations. The measured pressure values in the remaining 57 patients ranged between 6 and 93 mm Hg (mean 28.3 mm Hg). Eleven patients reached the prescribed effective compression pressure. Of these, formal errors were found in 6 patients, so that only 5 patients had correctly applied the compression bandages. CONCLUSION: Our data show that most patients with venous leg ulcers are not able to apply effective compression therapy with short-stretch bandages to themselves. Multilayer systems, adaptive compression bandages, and ulcer stocking systems today are possibly easier and more effective therapy options. Alternatively short-stretch bandages could be applied by trained persons but only under the control with pressure measuring probes. PMID- 29184986 TI - ? PMID- 29184987 TI - Ventilation during extracorporeal support : Why and how. AB - The main target of extracorporeal support is to achieve viable gas exchange, while minimizing the risk of ventilator-induced lung injury, achieved through a decreased mechanical ventilation load on the natural lung. However, during veno venous extracorporeal membrane oxygenation (ECMO), mechanical ventilation is still necessary in order to prevent lung collapse and/or if extracorporeal blood flow is not sufficient to guarantee adequate gas exchange. In this review, we will summarize the physiology of extracorporeal support and the rationale for continuing mechanical ventilation in this context. Furthermore, we will review the current clinical practice among ECMO centers and their suggestions regarding mechanical ventilator settings. While optimal ventilatory settings are still a matter of debate, the use of a strategy combining low tidal volume and limited inspiratory pressures is accepted worldwide. On the contrary, the choice of applied positive end-expiratory pressure (PEEP) varies between the total rest strategy and open lung strategy. Finally, the use of assisted or spontaneous ventilation will be discussed. PMID- 29184988 TI - Expression and characterization of a recombinant porcinized antibody against the E2 protein of classical swine fever virus. AB - Classical swine fever virus (CSFV) is the causative agent of classical swine fever (CSF), a highly contagious and economically important disease of pigs. The envelope glycoprotein E2 of CSFV is the major antigen that induces neutralizing antibodies and confers protection against CSFV infections. Previously, we developed a murine monoclonal antibody (MAb), HQ06, against the E2 protein of CSFV. To produce the antibody conveniently and stably, the genes coding for the variable regions of the heavy and light chains of HQ06 and constant region genes from the swine antibody were fused and cloned into lentiviral expression vectors to express a recombinant porcinized MAb (rHQ06Sw) in mammalian cells. rHQ06Sw was able to react with the E2 protein or the CSFV virions specifically in different assays. Notably, rHQ06Sw could neutralize CSFV infection in a dose-dependent manner. Taken together, the functional porcinized MAb rHQ06Sw was generated, which can be used to develop novel diagnostic assays or to investigate the structure and functions of the E2 protein. PMID- 29184989 TI - Enhanced avermectin production by Streptomyces avermitilis ATCC 31267 using high throughput screening aided by fluorescence-activated cell sorting. AB - Avermectins, produced by Streptomyces avermitilis, are important antiparasitic agents. The use of traditional microbial breeding methods for this organism has been limited by the low-throughput shake flask-based screening process. The unique growth cycle of actinomycetes makes the establishment of a reliable high throughput screening (HTS) process difficult. To enhance the efficiency of screening strains with high yields of avermectin, a HTS process aided by fluorescence-activated cell sorting (FACS) was established. Four different spore solutions were investigated for maintaining a relatively high viability of spores. Propidium iodide (PI) and fluorescein diacetate (FDA) were used to discriminate between dead and live spores using the FACS system. Spores stained with 7-MUg/mL PI and 15-MUg/mL FDA at 4 degrees C in the dark for 30 min resulted in optimum sorting. Spores were treated by atmospheric and room temperature plasma (ARTP). Single live spores were sorted and sprayed into 96 well microtiter plates containing 50 MUL of solid agar culture medium. Solid liquid combinatorial microculture was used for high-throughput avermectin culture. A high-titer avermectin producer (G9) was obtained from 5760 mutants after mutagenesis and HTS. Compared with the original strain, the titer was improved by 18.9% on flask culture and 20.6% on fermenter, respectively. The HTS process established in this study could easily be transferred to other similar target products produced by actinomycetes. PMID- 29184990 TI - Microbial biosensors for analytical applications. PMID- 29184991 TI - Universal fluorometric aptasensor platform based on water-soluble conjugated polymers/graphene oxide. AB - We designed a universal and sensitive fluorometric aptasensor that uses a fluorescence resonance energy transfer (FRET) mechanism. In the aptasensor, water soluble conjugated poly(9,9-bis(6'-N,N,N-trimethylammonium)hexyl)fluorine phenylene (PFP) is used as the energy donor and a carboxyfluorescein (FAM) labeled aptamer is used as the energy acceptor. Graphene oxide (GO) used as a quencher can specifically adsorb the aptamer, leading to quenching of the FAM fluorescence. In the presence of targets, the aptamer can change its conformation to prevent adsorption by GO. Strong FRET was thus obtained owing to the electrostatic interactions between PFP and the aptamer. In contrast, in the absence of targets, the FRET was weak because of GO specifically adsorbing the aptamer and quenching the fluorescence. Bisphenol A (a pollutant molecule) and dopamine (a biomolecule) were used as models to successfully validate the feasibility, universality, and high selectivity and sensitivity of this aptasensor. This method can detect BPA at environmentally relevant concentrations (less than 1 ng/mL) with a limit of detection of 0.005 ng/mL. A low limit of detection (1.0 nmol/L) was also obtained for dopamine. In addition, this aptasensor is applicable in real samples and in diluted human plasma and human serum. Good recovery rates from 95% to 105% and from 95% to 107% were obtained for bisphenol A and dopamine, respectively. Furthermore, adenosine detection was successfully achieved by the same mechanism, proving the universality. It is expected that the aptasensor could be applied in detecting other contaminants, biomolecules, and heavy metal ions by a change in only the aptamer sequence. Graphical abstract A universal and sensitive fluorometric aptasensor was developed for the detection of small molecules that uses a fluorescence resonance energy transfer (FRET) mechanism.

AB - A rapid, simple, and sensitive fluorescent immunochromatographic strip test (ICST) based on quantum dots (QDs) has been developed to detect 1-aminohydantoin (AHD), a major metabolite of nitrofurantoin in animal tissues. To achieve this, QD-labeled antibody conjugates, which consist of CdSe/ZnS QDs and monoclonal antibodies, were prepared by an activated ester method. Under optimal conditions, with the nitrophenyl derivative of AHD as the target, the ICST had a linear range from 0.1 to 100 ng/mL, with a correlation coefficient of 0.9656 and a 50% inhibitory concentration of 4.51 ng/mL. The limit of detection was 0.14 ng/g, which was below the minimum required performance limit of 1 MUg/kg for AHD established by the European Commission. The recoveries for AHD ranged from 81.5% to 108.2%, with coefficients of variation below 13%, based on intraday and interday analysis. Furthermore, for AHD in real samples, the ICST showed high reliability and high correlation with liquid chromatography-tandem mass spectrometry (correlation coefficient of 0.9916). To the best of our knowledge, this is the first report of a novel and sensitive method based on a fluorescent ICST to detect AHD below the minimum required performance limit. The ICST demonstrated high reliability, and could be ideally suited for rapid, simple, and on-site screening of AHD contamination in animal tissues.

AB - Phospholipids (PLs) represent a class of metabolites of interest for evaluating the relationship between diet and the development of several metabolic diseases. Given that PLs are rich in unsaturated fatty acids, they can be oxidized. Because of their structure and reactivity, oxidized phospholipids (PLs-Ox) are increasingly recognized as markers of oxidative stress and of various diseases associated with inflammation. Therefore, there is a growing interest in studying PLs-Ox in lipidomics. Because of their limited commercial availability, very little information is currently available in databases to identify these molecules. The aim of this study is to acquire new knowledge about PLs-Ox in order to propose an analytical strategy for their analyses. For this purpose, a synthesis method of PLs-Ox, in auto-oxidation, has been developed and applied on phosphatidylcholine and phosphatidylethanolamine molecular species with various chain lengths, degree, and position of unsaturations. An analysis method based on mass (MS) and tandem mass spectrometry coupled to electrospray ionization was then developed and enabled the identification of a great diversity of long- and short-chain oxidation products. Formation kinetics of oxidation products was evaluated. Results showed that the formation of oxidized compounds was largely influenced by the degree of unsaturation on fatty acid chains. Oxidation time promotes the formation of some biologically important oxidation products. Coupling the MS method with liquid chromatography in flow injection analysis mode enabled the development of a full analytical strategy. Structural analysis of PLs Ox allowed the enrichment of databases with important information to identify these molecules in biological matrices. PMID- 29184994 TI - Synthetic biology for microbial heavy metal biosensors. AB - Using recombinant DNA technology, various whole-cell biosensors have been developed for detection of environmental pollutants, including heavy metal ions. Whole-cell biosensors have several advantages: easy and inexpensive cultivation, multiple assays, and no requirement of any special techniques for analysis. In the era of synthetic biology, cutting-edge DNA sequencing and gene synthesis technologies have accelerated the development of cell-based biosensors. Here, we summarize current technological advances in whole-cell heavy metal biosensors, including the synthetic biological components (bioparts), sensing and reporter modules, genetic circuits, and chassis cells. We discuss several opportunities for improvement of synthetic cell-based biosensors. First, new functional modules must be discovered in genome databases, and this knowledge must be used to upgrade specific bioparts through molecular engineering. Second, modules must be assembled into functional biosystems in chassis cells. Third, heterogeneity of individual cells in the microbial population must be eliminated. In the perspectives, the development of whole-cell biosensors is also discussed in the aspects of cultivation methods and synthetic cells.

AB - Protein diffusion in living cells might differ significantly from that measured in vitro. Little is known about the effect of globular protein size on rotational diffusion in cells because each protein has distinct surface properties, which result in different interactions with cellular components. To overcome this problem, the B1 domain of protein G (GB1) and several concatemers of the protein were labeled with 5-fluorotryptophan and studied by 19F NMR in Escherichia coli cells, Xenopus laevis oocytes, and in aqueous solutions crowded with glycerol, or Ficoll70TM and lysozyme. Relaxation data show that the size dependence of protein rotation in cells is due to weak interactions of the target protein with cellular components, but the effect of these interactions decreases as protein size increases. The results provide valuable information for interpreting protein diffusion data acquired in living cells. Graphical abstract Size matters. The protein rotational mobility in living cells was assessed by 19F NMR. The size dependence effect may arise from weak interactions between protein and cytoplasmic components.

AB - Polymeric ionic liquids (PILs) with 1-vinyl-3-ethylimidazolium cations and two different anions of Br- and PF6- were assembled onto the surface of graphene (G) nanosheets. The derived two composites, i.e., PIL(Br)-G and PIL(PF6)-G, were further efficiently immobilized onto the surface of silica nanoparticles via self assembly technique. The obtained two PIL-G/SiO2 nanocomposites exhibited diverse adsorption performances toward proteins through adjusting the anions of PILs. Electrostatic attractions between proteins and the nanocomposites dominated protein adsorption, while the presence of PF6- anions weakened electrostatic interactions and deteriorated the selective adsorption of target protein, i.e., bovine serum albumin (BSA) in this case. Specifically, PIL(Br)-G/SiO2 nanocomposite displayed high selectivity toward BSA and a high adsorption efficiency of ca. 98% was achieved for 100 mg L-1 BSA in a Britton-Robinson (B-R) buffer at pH 5. HPLC analysis demonstrated the selectivity of PIL(Br)-G/SiO2 nanocomposite toward BSA in the presence of abundant hemoglobin and cytochrome c. The practical applicability was verified by performing selective isolation of human serum albumin (HSA) from human whole blood.

AB - A series of beta-cyclodextrin derivatives were designed and synthesized. The derivatives were investigated as functional monomers in molecularly imprinted polymeric solid-phase microextraction (MIP-SPME) fiber coatings. The coatings, with a layer thickness of 250 MUm, were immobilized onto stainless steel using a capillary tube as a mold. This study employed a simple, easy, and reproducible method to prepare uniform coatings for polychlorophenols extraction. The combination of molecular inclusion effects and the molecular imprinting sites was expected to enhance the molecular recognition ability for polychlorophenols. Compared with non-imprinted polymer coatings and MIP coatings with methacrylic acid as the functional monomer, the beta-cyclodextrin MIP-SPME coatings exhibited significantly higher extraction amounts and excellent selectivity to the template of triclosan. The MIP-SPME coatings exhibited a favorable synergistic extraction capacity resulting from the beta-cyclodextrin cavity and molecularly imprinted binding sites. The method of beta-cyclodextrin MIP-SPME coupled with high performance liquid chromatography (HPLC) for triclosan and polychlorophenols analysis in real water samples was developed. The limit of quantification was 1 MUg/L for the three polychlorophenols. The recovery for three analytes ranged from 83.71% to 109.98%, with the relative standard deviation (RSD) of 2.83% to 12.19%. The beta-cyclodextrin MIP-SPME fiber coatings could be used for at least 100 cycles. Graphical Abstract Synergistic effects in beta-cyclodextrin MIP-SPME.

AB - In contrast to biochemical reactions, which are often carried out under automatic control and maintained overnight, the automation of chemical analysis is usually neglected. Samples are either analyzed in a rudimentary fashion using in situ techniques, or aliquots are withdrawn and stored to facilitate more precise offline measurements, which can result in sampling and storage errors. Therefore, in this study, we implemented automated reaction control, sampling, and analysis. As an example, the activities of xylanases on xylotetraose and soluble xylan were examined using high-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD). The reaction was performed in HPLC vials inside a temperature-controlled DionexTM AS-AP autosampler. It was started automatically when the autosampler pipetted substrate and enzyme solution into the reaction vial. Afterwards, samples from the reaction vial were injected repeatedly for 60 min onto a CarboPacTM PA100 column for analysis. Due to the rapidity of the reaction, the analytical method and the gradient elution of 200 mM sodium hydroxide solution and 100 mM sodium hydroxide with 500 mM sodium acetate were adapted to allow for an overall separation time of 13 min and a detection limit of 0.35-1.83 mg/L (depending on the xylooligomer). This analytical method was applied to measure the soluble short-chain products (xylose, xylobiose, xylotriose, xylotetraose, xylopentaose, and longer xylooligomers) that arise during enzymatic hydrolysis. Based on that, the activities of three endoxylanases (EX) were determined as 294 U/mg for EX from Aspergillus niger, 1.69 U/mg for EX from Bacillus stearothermophilus, and 0.36 U/mg for EX from Bacillus subtilis.

AB - Mass spectrometry (MS) imaging is a useful tool for direct and simultaneous visualization of specific molecules. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is used to evaluate the abundance of molecules in tissues using sample homogenates. To date, however, LC-MS/MS has not been utilized as an imaging tool because spatial information is lost during sample preparation. Here we report a new approach for LC-MS/MS imaging using a thermal film-based laser microdissection (LMD) technique. To isolate tissue spots, our LMD system uses a 808-nm near infrared laser, the diameter of which can be freely changed from 2.7 to 500 MUm; for imaging purposes in this study, the diameter was fixed at 40 MUm, allowing acquisition of LC-MS/MS images at a 40-MUm resolution. The isolated spots are arranged on a thermal film at 4.5-mm intervals, corresponding to the well spacing on a 384-well plate. Each tissue spot is handled on the film in such a manner as to maintain its spatial information, allowing it to be extracted separately in its individual well. Using analytical LC-MS/MS in combination with the spatial information of each sample, we can reconstruct LC-MS/MS images. With this imaging technique, we successfully obtained the distributions of pilocarpine, glutamate, gamma-aminobutyric acid, acetylcholine, and choline in a cross-section of mouse hippocampus. The protocol we established in this study is applicable to revealing the neurochemistry of pilocarpine model of epilepsy. Our system has a wide range of uses in fields such as biology, pharmacology, pathology, and neuroscience. Graphical abstract Schematic Indication of LMD-LC MS/MS imaging. PMID- 29185003 TI - Ultrasound measurements of Achilles tendon length using skin markings are more reliable than extended-field-of-view imaging. AB - PURPOSE: Elongation of the Achilles tendon has been associated with poorer function in patients treated for ruptures. This has led to the development of various ultrasound-based measurements, and the purpose of the present study was to compare the reliability of three ultrasound-based measuring procedures. METHODS: Twenty healthy individuals (40 tendons) were assessed by two testers at two occasions, 12 weeks apart. The tendon length was measured from the calcaneal insertion to the mid-sagittal muscle tendon junction (MTJ) using skin markings or extended-field-of-view (EFOV) imaging, or from the calcaneal insertion to the distal medial MTJ using skin markings. Test-retest and inter-tester reliability as well as side-to-side length differences were assessed for all three procedures. RESULTS: Test-retest intraclass correlation coefficients (ICCs) for measurements from the mid-sagittal MTJ using EFOV imaging and skin markings, and from the distal medial MTJ using skin markings were 0.83, 0.90 and 0.96 for tester 1 and 0.87, 0.91 and 0.96 for tester 2, respectively. The corresponding inter-tester ICCs were 0.85, 0.91 and 0.96. Side-to-side lengths were significantly different for measurements from the mid-sagittal MTJ and the distal medial MTJ using skin markings, with mean differences of 0.3 and 0.4 cm, respectively. CONCLUSIONS: Test-retest and inter-tester ICCs were excellent for all three measuring procedures, however, the use of skin markings provided consistently better agreement and reliability compared to EFOV images. The best agreement and highest ICCs were achieved for measurements from the distal medial MTJ, but side-to-side length differences warrant caution when contralateral measurements are used to evaluate tendon elongation. LEVEL OF EVIDENCE: III. PMID- 29185004 TI - Poor knee function after ACL reconstruction is associated with attenuated landing force and knee flexion moment during running. AB - PURPOSE: Poor knee function after anterior cruciate ligament reconstruction (ACLR) may increase the risk of future knee symptoms and knee osteoarthritis via abnormal knee joint loading patterns, particularly during high-impact activity. This study aimed to assess the relationship between poor self-reported or clinically measured knee function and knee moments/vertical ground reaction force (vGRF) in individuals following ACLR. METHODS: 61 participants (mean 16.5 +/- 3 months following ACLR, 23 women) completed a patient-reported knee function questionnaire and three hop tests (% of uninvolved limb). Participants were divided into satisfactory and poor knee function groups (poor < 85% patient reported knee function and/or < 85% hop test symmetry). The knee biomechanics of both groups were assessed with three-dimensional motion analysis during the stance phase of overland running at self-selected speeds, and the association between knee function and knee moments was assessed using analysis of covariance with running speed as a covariate. RESULTS: Participants with poor knee function (n = 30) ran with significantly smaller peak knee flexion moments (moderate effect size 0.7, p = 0.03) and significantly smaller peak vGRFs (large effect size 1.0, p = 0.002) compared to those with satisfactory knee function (n = 31). No significant differences were observed for knee adduction and knee external rotation moments or knee kinematics. CONCLUSION: Individuals following ACLR with poor self-reported knee function and/or hop test performance demonstrate knee moments during running that may be associated with lower knee joint contact forces. These findings provide greater understanding of the relationship between knee biomechanics during running and clinical assessments of knee function. LEVEL OF EVIDENCE: III. Cross-sectional study. PMID- 29185006 TI - Endoscopic shelf acetabuloplasty can improve clinical outcomes and achieve return to sports-related activity in active patients with hip dysplasia. AB - PURPOSE: To investigate clinical outcomes and return to sports-related activity following endoscopic shelf acetabuloplasty combined with labral repair in the treatment of the active patients with developmental dysplasia of the hip (DDH). METHODS: Between 2011 and 2013, 32 patients (36 hips; 11 males and 21 females; 11 right 17 left 4 bilateral; median age 28.5, range 12-51 years), who underwent endoscopic shelf acetabuloplasty combined with labral repair and met the inclusion criteria were enrolled in this study. There was a minimum follow-up of 2 years (average 32.3 +/- 3 months, range 24-48 months). Patient-reported outcome (PRO) scores including the modified Harris Hip Score (MHHS) and Non-Arthritis Hip Score (NAHS) were obtained preoperatively and at final follow-up for the assessment of surgical outcomes. RESULTS: The mean MHHS significantly improved from 68.4 +/- 14.3 (range 23.1-95.7) preoperatively to 94.5 +/- 8.5 (range 66 100) at final follow-up (p = 0.001). Similarly, the NAHS also significantly improved from 51.3 +/- 11.9 (range 23-76) preoperatively to 73.0 +/- 7.4 (range 44-80) at final follow-up (p = 0.001). The mean LCE angle significantly increased postoperatively but partially decreased at final follow-up (mean preoperative versus postoperative versus final follow-up: 16.0 range 5-24, versus 40.1 range 27-58, versus 30.1 range 20-41. p = 0.001, respectively). There were 3 patients who returned to a higher activity level, 20 patients who returned to the same activity level, and 6 patients who returned to a lower activity level. The mean period from surgery to return to play was 9.0 +/- 3.5 months (range 5-18). CONCLUSION: Endoscopic shelf acetabuloplasty provides promising clinical outcomes and return to sports-related activity for active patients with DDH. LEVEL OF EVIDENCE: Level IV. PMID- 29185005 TI - Larger range of motion and increased return to activity, but higher revision rates following unicompartmental versus total knee arthroplasty in patients under 65: a systematic review. AB - PURPOSE: Due to the lack of comparative studies, a systematic review was conducted to determine revision rates of unicompartmental and total knee arthroplasty (UKA and TKA), and compare functional outcomes, range of motion and activity scores in patients less than 65 years of age. METHODS: A literature search was performed using PubMed, Embase, and Cochrane systems since 2000. 27 UKA and 33 TKA studies were identified and included. Annual revision rate (ARR), functional outcomes, and return to activity were assessed for both types of arthroplasty using independent t tests. RESULTS: Four level I studies, 12 level II, 16 level III, and 29 level IV were included, which reported on outcomes in 2224 UKAs and 4737 TKAs. UKA studies reported 183 revisions, yielding an ARR of 1.00 and extrapolated 10-year survivorship of 90.0%. TKA studies reported 324 TKA revisions, resulting in an ARR of 0.53 and extrapolated 10-year survivorship of 94.7%. Functional outcomes scores following UKA and TKA were equivalent, however, following UKA larger ROM (125 degrees versus 114 degrees , p = 0.004) and higher UCLA scores were observed compared to TKA (6.9 versus 6.0, n.s.). CONCLUSION: These results show that good-to-excellent outcomes can be achieved following UKA and TKA in patients less than 65 years of age. A higher ARR was noted following UKA compared to TKA. However, improved functional outcomes, ROM and return to activity were found after UKA than TKA in this young population. Comparative studies are needed to confirm these findings and assess factors contributing to failure at the younger patient population. Outcomes of UKA and TKA in patients younger than 65 years are both satisfying, and therefore, both procedures are not contraindicated at younger age. UKA has several important advantages over TKA in this young and frequently more active population. LEVEL OF EVIDENCE: IV. PMID- 29185007 TI - Awareness and Adoption of Soil and Water Conservation Technologies in a Developing Country: A Case of Nabajuzi Watershed in Central Uganda. AB - Soil and water conservation technologies have been widely available in most parts of Uganda. However, not only has the adoption rate been low but also many farmers seem not to be aware of these technologies. This study aims at identifying the factors that influence awareness and adoption of soil and water conservation technologies in Nabajuzi watershed in central Uganda. A bivariate probit model was used to examine farmers' awareness and adoption of soil and water conservation technologies in the watershed. We use data collected from the interview of 400 households located in the watershed to understand the factors affecting the awareness and adoption of these technologies in the study area. Findings indicate that the likelihood of being aware and adopting the technologies are explained by the age of household head, being a tenant, and number of years of access to farmland. To increase awareness and adoption of technologies in Uganda, policymakers may expedite the process of land titling as farmers may feel secure about landholding and thus adopt these technologies to increase profitability and productivity in the long run. Incentive payments to farmers residing in the vulnerable region to adopt these considered technologies may help to alleviate soil deterioration problems in the affected area. PMID- 29185008 TI - Satellite Images Combined with Field Data Reveal Negative Changes in the Distribution of Babassu Palms after Clearing off Amazonian Forests. AB - When the Amazonian rain forest is cut to create pasture, some of the original vegetal species survive clearing, even expressing their ability to invade agro systems. It is true of the babassu palm, which can be considered, paradoxically, a natural resource by the "Interstate Movement of Babassu Fruit Breaker Women" or as native weed by land owners-farmers. To manage potential conflict of land uses, we study here the current density of this palm tree in different habitats, based on a combination of field data and remote sensing data. Firstly, we checked that the field survey methodology (i.e., counting free-trunk palm trees over 20 cm in circumference) provides density values compatible with those stemming from satellite images interpretation. We can see then that, a PA-Benfica Brazilian territory revealed an average density of the babassu lower in pastures (2.86 ind/ha) than in the dense forest (4.72 ind/ha) from which they originate and than in fallow land (4.31 ind/ha). We analyze in detail density data repartition in three habitats and we discuss results from the literature on the density of this palm tree versus its resilience at different developmental stages after forest clearing, depending on anthropogenic-or not-factors, including solar radiation, fire, weeding, clear cutting, burying fruit, and competition with forage grass. All these results can be exploited for the design of future management plans for the babassu palm and we think that the linked methodology and interdisciplinary approach can be extended to others palms and trees species in similar problematic issues. PMID- 29185009 TI - 42nd Annual Meeting - Vancouver, Canada, June 20 - 24, 2017. PMID- 29185010 TI - Preliminary results on response assessment using 68Ga-HBED-CC-PSMA PET/CT in patients with metastatic prostate cancer undergoing docetaxel chemotherapy. AB - PURPOSE: To investigate the value of 68Ga-HBED-CC PSMA (68Ga-PSMA) PET/CT for response assessment in metastatic castration-sensitive and castration-resistant prostate cancer (mCSPC and mCRPC) during docetaxel chemotherapy. METHODS: 68Ga PSMA PET/CT was performed in seven mCSPC patients before and after six cycles of upfront docetaxel chemotherapy and in 16 mCRPC patients before and after three cycles of palliative docetaxel chemotherapy. Radiographic treatment response was evaluated separately on the 68Ga-PSMA PET and CT datasets. Changes in 68Ga-PSMA uptake (SUVmean) were assessed on a per-patient and a per-lesion basis using the PERCIST scoring system with slight modification. Treatment response was defined as absence of any PSMA uptake in all target lesions on posttreatment PET (complete response, CR) or a decrease in summed SUVmean of >=30% (partial response, PR). The appearance of a new PET-positive lesion or an increase in summed SUVmean of >=30% (progressive disease, PD) indicated nonresponse. A moderate change in summed SUVmean (between -30% and +30%) without a change in the number of target lesions was defined as stable disease (SD). For treatment response assessment on CT, RECIST1.1 criteria were used. Radiographic responses on 68Ga-PSMA PET [RR(PET)] and on CT [RR(CT)] were compared and correlated with biochemical response (BR). A decrease in serum PSA level of >=50% was defined as biochemical PR. RESULTS: Biochemical PR was found in six of seven patients with mCSPC (86%, 95% confidence interval 42% to 99.6%). The concordance rate was higher between BR and RR(PET) than between BR and RR(CT) (6/7 vs. 3/6 patients. 68Ga-PSMA PET and CT were concordant in only three patients (50%, 12% to 88%). In mCRPC patients, biochemical PR was found in six of 16 patients (38%, 15% to 65%). Outcome prediction was concordant between BR and RR(PET) in nine of 16 patients (56%), and between BR and RR(CT) in only four of 12 patients (33%) with target lesions on CT. 68Ga-PSMA PET and CT results corresponded in seven of 12 patients (58%, 28% to 85%). CONCLUSION: Our preliminary results suggest that 68Ga-PSMA PET might be a promising method for treatment response assessment in mCSPC and mCRPC. The data indicate that for different metastatic sites, the performance of 68Ga PSMA PET in response assessment might be superior to that of the conventional CT approach and could help differentiate between progressive disease and treatment response. Because of the limited number of patients, the differences revealed in our study were not statistically significant. Thus larger and prospective studies are clearly needed and warranted to confirm the value of 68Ga-PSMA PET as an imaging biomarker for response assessment. PMID- 29185011 TI - Plasma concentrations of 8-hydroxy-2'-deoxyguanosine and risk of kidney disease and death in individuals with type 1 diabetes. AB - AIMS/HYPOTHESIS: Oxidative stress is involved in the pathogenesis of diabetic kidney disease. We evaluated the association between 8-hydroxy-2'-deoxyguanosine (8-OHdG), a marker of DNA oxidative damage, and end-stage renal disease (ESRD) or death in individuals with type 1 diabetes. METHODS: Plasma 8-OHdG concentrations were measured at baseline in participants with type 1 diabetes from GENEDIAB (n = 348) and GENESIS (n = 571) cohorts. A follow-up was conducted in 205 and 499 participants for a mean +/- SD duration of 8.9 +/- 2.3 years and 5.2 +/- 1.9 years, respectively. We tested associations between 8-OHdG concentrations and urinary albumin concentration (UAC) or eGFR at baseline, and the risk of ESRD or all-cause mortality during follow-up. Analyses were performed in pooled cohorts. RESULTS: The highest UAC (geometric mean [95% CI]) was observed in the third 8 OHdG tertile (tertile 1, 9 [6, 13] mg/l; tertile 2, 10 [7, 16] mg/l; tertile 3, 16 [10, 25] mg/l; p = 0.36 for tertile 1 vs tertile 2 and p = 0.003 for tertile 3 vs tertile 1) after adjustment for potential confounding covariates. The lowest eGFR (mean [95% CI]) was observed in the third tertile (tertile 1, 87 [82, 93] ml min-1 1.73 m-2; tertile 2, 88 [82, 94] ml min-1 1.73 m-2; tertile 3, 74 [68, 80] ml min-1 1.73 m-2; p = 0.61 for tertile 1 vs tertile 2; p < 0.001 for tertile 3 vs tertile 1). ESRD and death occurred in 48 and 64 individuals, respectively. The HR for ESRD, but not death, was higher in the third tertile than in the first (tertile 2 vs tertile 1, 1.45 [0.45, 5.04], p = 0.54; tertile 3 vs tertile 1, 3.05 [1.16, 9.60], p = 0.02) after multiple adjustments. CONCLUSIONS/INTERPRETATION: Higher plasma concentrations of 8-OHdG were independently associated with increased risk of kidney disease in individuals with type 1 diabetes, suggesting that this marker can be used to evaluate the progression of diabetic kidney disease. PMID- 29185013 TI - Assessment of arterially hyper-enhancing liver lesions using virtual monoenergetic images from spectral detector CT: phantom and patient experience. AB - PURPOSE: To investigate a benefit from virtual monoenergetic reconstructions (VMIs) for assessment of arterially hyper-enhancing liver lesions in phantom and patients and to compare hybrid-iterative and spectral image reconstructions of conventional images (CI-IR and CI-SR). METHODS: All imaging was performed on a SDCT (Philips Healthcare, Best, The Netherlands). Images of a non-anthropomorphic phantom with a lesion-mimicking insert (containing iodine in water solution) and arterial-phase images from contrast-enhanced patient examinations were evaluated. VMIs (40-200 keV, 10 keV increment), CI-IR, and CI-SR were reconstructed using different strengths of image denoising. ROIs were placed in lesions, liver/matrix, muscle; signal-to-noise, contrast-to-noise, and lesion-to-liver ratios (SNR, CNR, and LLR) were calculated. Qualitatively, 40, 70, and 110 keV and CI images were assessed by two radiologists on five-point Likert scales regarding overall image quality, lesion assessment, and noise. RESULTS: In phantoms, SNR was increased threefold by VMI40keV compared with CI-IR/SR (5.8 +/- 1.1 vs. 18.8 +/- 2.2, p <= 0.001), while no difference was found between CI-IR and CI-SR (p = 1). Denoising was capable of noise reduction by 40%. In total, 20 patients exhibiting 51 liver lesions were assessed. Attenuation was the highest in VMI40keV, while image noise was comparable to CI-IR resulting in a threefold increase of CNR/LLR (CI-IR 1.3 +/- 0.8/4.4 +/- 2.0, VMI40keV: 3.8 +/- 2.7/14.2 +/ 7.5, p <= 0.001). Subjective lesion delineation was the best in VMI40keV image (p <= 0.01), which also provided the lowest perceptible noise and the best overall image quality. CONCLUSIONS: VMIs improve assessment of arterially hyper enhancing liver lesions since they increase lesion contrast while maintaining low image noise throughout the entire keV spectrum. These data suggest that to consider VMI screening after arterially hyper-enhancing liver lesions. PMID- 29185014 TI - Characterizing indeterminate liver lesions in patients with localized pancreatic cancer at the time of diagnosis. AB - BACKGROUND: In patients with newly diagnosed pancreatic cancer, the classification of indeterminate liver lesions is an unanswered clinical dilemma as misclassification of these lesions can impact the assignment of clinical stage and subsequent treatment planning. Our objective was to design a standardized classification system to more accurately define the risk of malignancy in indeterminate liver lesions. METHODS: In this retrospective study, patients with localized, non-metastatic pancreatic cancer were identified and pre-treatment computed tomography (CT) scans were evaluated for the presence or absence of liver lesions. Liver lesions were defined as definitely benign (1) or indeterminate (2). Indeterminate lesions were further sub-classified as either indeterminate probably benign (2B) or indeterminate possibly malignant (2M). The index liver lesion was evaluated on follow-up imaging for stability or unequivocal disease progression. RESULTS: From 2008 to 2015, 304 patients with localized, non-metastatic pancreatic cancer were identified and 125 (41%) patients had liver lesions. Of the 125 patients, the liver lesions in 35 (28%) were classified as definitely benign and in 90 (72%) patients they were classified as indeterminate. The 90 patients with indeterminate lesions included 80 (89%) classified as indeterminate probably benign (2B) and 10 (11%) classified as indeterminate possibly malignant (2M). After a median follow-up of 56 weeks, no patient with a definitely benign lesion had metastatic disease progression of the index lesion. Of the 90 patients with indeterminate liver lesions, the index lesion progressed to unequivocal liver metastasis in 8 (9%) patients; 5 (6%) of the 80 lesions classified as indeterminate probably benign (2B), and 3 (30%) of the ten lesions classified as indeterminate possibly malignant (2M). The sensitivity of the classification system was 38% and the specificity was 91%. The positive predictive value was 30% and the negative predictive value was 94%. CONCLUSIONS: A significant proportion of patients with localized pancreatic cancer will have liver lesions identified at the time of diagnosis and most of these lesions will have indeterminate characteristics. A classification system which further stratifies indeterminate liver lesions by malignant potential can assist clinicians in determining optimal treatment plan and is associated with a high negative predictive value. PMID- 29185015 TI - Esophageal abnormalities in gastroesophageal reflux disease. AB - Fluoroscopic esophagography is a widely available, safe, and inexpensive test for detecting gastroesophageal reflux disease. In this article, we review the technique for performing a high-quality esophagram, including upright, double contrast views of the esophagus and cardia with high-density barium; prone, single-contrast views of the esophagus with low-density barium; and evaluation of gastroesophageal reflux. We then discuss the radiographic findings associated with gastroesophageal reflux disease, including esophageal dysmotility, reflux esophagitis, peptic strictures, and Barrett's esophagus. Finally, we consider the differential diagnosis for the various radiographic findings associated with this condition. When carefully performed and interpreted, the esophagram is a useful test for evaluating gastroesophageal reflux disease and its complications. PMID- 29185016 TI - The radiological myometrial appearance after cesarean section: is it associated with postpartum complications and subsequent delivery outcome? AB - PURPOSE: To evaluate whether the characteristics of the radiological uterine myometrial discontinuity (RMD) is associated with maternal-neonatal outcomes and post-cesarean section (CS) complications. A secondary aim was to describe the evolution of the CT uterine surgical incision and the related outcome of a subsequent trial of labor after cesarean (TOLAC). METHODS: Single center retrospective cohort study of CT scans was performed within 6 weeks from cesarean delivery. Demographic characteristics of patients were recorded (age, intrapartum fever, CS data, and hospital stay length). Abdominopelvic CT scans were performed using a multidetector CT (16 or 256 slice) with intravenous contrast material. CT analysis was performed by two radiologists in consensus. The RMD seen as low attenuation gap in expected incision site was assessed for: visualization, thickness, and presence of gas. Logistic regression analysis was fitted to assess the relationship of the delivery-CT time interval with the presence of RMD and gas. RESULTS: Of a total of 75,791 births during the study period there were 8775 CS (11.6%). The study group consisted of 101 CTs in 84 woman after CS. RMD defined in 73 (72.2%) of all CT exams; the mean RMD thickness was 7 mm +/- 3.9, "RMD gas" observed in 15 (17.9%) of CT exams. RMD thickness or gas presence were strongly associated with a CS-1st CT exam time interval of less than 7 days, OR 5.8 [CI 1.5-22.6], p = 0.010, but not with maternal, delivery, or neonatal characteristics. A subsequent successful vaginal birth was achieved in 75% of the patients with no uterine rupture, regardless of the RMD gas presence. CONCLUSION: RMD gas visualization on CT is not associated with febrile morbidity, cesarean characteristics, and subsequent TOLAC results. RMD gas is a normal post-operative finding and should not lead to changes in the postpartum delivery complication management or recommendations for the future mode of delivery. PMID- 29185012 TI - Systems biology of the IMIDIA biobank from organ donors and pancreatectomised patients defines a novel transcriptomic signature of islets from individuals with type 2 diabetes. AB - AIMS/HYPOTHESIS: Pancreatic islet beta cell failure causes type 2 diabetes in humans. To identify transcriptomic changes in type 2 diabetic islets, the Innovative Medicines Initiative for Diabetes: Improving beta-cell function and identification of diagnostic biomarkers for treatment monitoring in Diabetes (IMIDIA) consortium ( www.imidia.org ) established a comprehensive, unique multicentre biobank of human islets and pancreas tissues from organ donors and metabolically phenotyped pancreatectomised patients (PPP). METHODS: Affymetrix microarrays were used to assess the islet transcriptome of islets isolated either by enzymatic digestion from 103 organ donors (OD), including 84 non-diabetic and 19 type 2 diabetic individuals, or by laser capture microdissection (LCM) from surgical specimens of 103 PPP, including 32 non-diabetic, 36 with type 2 diabetes, 15 with impaired glucose tolerance (IGT) and 20 with recent-onset diabetes (<1 year), conceivably secondary to the pancreatic disorder leading to surgery (type 3c diabetes). Bioinformatics tools were used to (1) compare the islet transcriptome of type 2 diabetic vs non-diabetic OD and PPP as well as vs IGT and type 3c diabetes within the PPP group; and (2) identify transcription factors driving gene co-expression modules correlated with insulin secretion ex vivo and glucose tolerance in vivo. Selected genes of interest were validated for their expression and function in beta cells. RESULTS: Comparative transcriptomic analysis identified 19 genes differentially expressed (false discovery rate <=0.05, fold change >=1.5) in type 2 diabetic vs non-diabetic islets from OD and PPP. Nine out of these 19 dysregulated genes were not previously reported to be dysregulated in type 2 diabetic islets. Signature genes included TMEM37, which inhibited Ca2+-influx and insulin secretion in beta cells, and ARG2 and PPP1R1A, which promoted insulin secretion. Systems biology approaches identified HNF1A, PDX1 and REST as drivers of gene co-expression modules correlated with impaired insulin secretion or glucose tolerance, and 14 out of 19 differentially expressed type 2 diabetic islet signature genes were enriched in these modules. None of these signature genes was significantly dysregulated in islets of PPP with impaired glucose tolerance or type 3c diabetes. CONCLUSIONS/INTERPRETATION: These studies enabled the stringent definition of a novel transcriptomic signature of type 2 diabetic islets, regardless of islet source and isolation procedure. Lack of this signature in islets from PPP with IGT or type 3c diabetes indicates differences possibly due to peculiarities of these hyperglycaemic conditions and/or a role for duration and severity of hyperglycaemia. Alternatively, these transcriptomic changes capture, but may not precede, beta cell failure. PMID- 29185017 TI - Incidence of Post-ablation Syndrome Following Image-Guided Percutaneous Cryoablation of Renal Cell Carcinoma: A Prospective Study. AB - PURPOSE: To prospectively evaluate the incidence of post-ablation syndrome (fever and flu-like symptoms) and impact on the quality of life in the first 10 days following percutaneous image-guided cryoablation for renal cell carcinoma (RCC). MATERIALS AND METHODS: A prospective study of all cryoablation procedures with biopsy proven RCC was conducted with institutional review board approval between 08/2012 and 04/2016. Sixty-four patients (43 males and 21 females) underwent cryoablation. Mean age was 68 (range 24-86). A telephone questionnaire survey was conducted on days 1, 3, 5, 7 and 10 following cryoablation, and complications were recorded. Data collected included temperature, degree of flu-like symptoms, severity of pain, percentage of pain relief with analgesics, interference with general activity and with work (graded on a 0-10 Numeric Intensity Scale). RESULTS: Following cryoablation, six patients (9%) out of 64 developed post ablation syndrome. Thirty-three patients (52%) developed flu-like symptoms only, which completely resolved by day 10 in 25 patients (39%). One patient had pyrexia only, which was self- limiting by day 10. Twenty-four patients (38%) were asymptomatic. Pain (mean score = 2.1) and interference on general activities (mean score = 1.8) and work (mean score = 2) following cryoablation peaked on day 3 and improved subsequently. Forty-six patients (72%) had 90-100% pain relief by day 10. No major complications were observed. CONCLUSION: The full spectrum of post-ablation syndrome following cryoablation occurs in approximately 9% of patients; however, 61% of patients experience flu-like symptoms in the first 10 days, which are self-limiting. PMID- 29185018 TI - Evaluation of Resources Necessary for Provision of Trauma Care in Botswana: An Initiative for a Local System. AB - BACKGROUND: Developing countries face the highest incidence of trauma, and on the other hand, they do not have resources for mitigating the scourge of these injuries. The World Health Organization through the Essential Trauma Care (ETC) project provides recommendations for improving management of the injured and building up of systems that are effective in low-middle-income countries (LMICs). This study uses ETC project recommendations and other trauma-care guidelines to evaluate the current status of the resources and organizational structures necessary for optimal trauma care in Botswana; an African country with relatively good health facilities network, subsidized public hospital care and a functioning Motor Vehicle Accident fund covering road traffic collision victims. METHOD: A cross-sectional descriptive design employed convenience sampling for recruiting high-volume trauma hospitals and selecting candidates. A questionnaire, checklist, and physical verification of resources were utilized to evaluate resources, staff knowledge, and organization-of-care and hospital capabilities. Results are provided in plain descriptive language to demonstrate the findings. RESULTS: Necessary consumables, good infrastructure, adequate numbers of personnel and rehabilitation services were identified all meeting or exceeding ETC recommendations. Deficiencies were noted in staff knowledge of initial trauma care, district hospital capability to provide essential surgery, and the organization of trauma care. CONCLUSION: The good level of resources available in Botswana may be used to improve trauma care: To further this process, more empowering of high-volume trauma hospitals by adopting trauma-care recommendations and inclusive trauma-system approaches are desirable. The use of successful examples on enhanced surgical skills and capabilities, effective trauma-care resource management, and leadership should be encouraged.

PMID- 29185020 TI - The Positive Lymph Node Number and Postoperative N-Staging Used to Estimate Survival in Patients with Differentiated Thyroid Cancer: Results from the Surveillance, Epidemiology, and End Results Dataset (1988-2008). AB - BACKGROUND: Lymph node metastasis is important when evaluating the prognosis of patients with differentiated thyroid cancer (DTC). However, the current N-staging system cannot fully reflect the clinical significance of cervical lymph node metastasis in DTC. In this study, we employed Surveillance, Epidemiology, and End Results (SEER)-registered DTC cases with lymph node metastasis to determine whether the positive lymph node number (PLNN) could be used to improve stratification of patients in terms of survival. METHODS: We used the SEER dataset to identify all DTC patients with at least one positive cervical lymph node who were examined between 1988 and 2008. Multivariable modeling was used to compare cancer-specific survival (CSS) and overall survival (OS) and to calculate different PLNN cutoff points. RESULTS: In total, 14,359 pN + DTC patients identified in the SEER were included. In multivariate Cox regression analysis, the PLNN was significantly associated with both CSS and OS, whereas neither the lymph node ratio (LNR) nor the (numbers of) lymph nodes examined (LNE) were so associated. The highest C-index value (0.933) and the lowest AIC value (9362.687) obtained indicated that the PLNN better predicted the CSS of DTC than did the LNR or LNE. As the p values for both CSS and OS were minimized, and as the PLNN performed best when cases were grouped, PLNN cutoff points of 10 and 3/10 efficiently stratified DTC patients into two and three levels, respectively. Based on the 3/10 trichotomy, the benefits of radioactive iodine (RAI) treatment were evaluated for each group. Such treatment afforded about a 10% survival benefit in patients with more than 10 lymph node metastases. CONCLUSIONS: Compared with the LNR and LNE under different statistical models, PLNN was superior in terms of DTC staging. A cutoff point of 3/10 was optimal for stratifying patients according to prognosis and was of clinical significance in terms of RAI treatment selection. PMID- 29185022 TI - Change and dispersion of QT interval during treatment with quetiapine extended release versus aripiprazole in children and adolescents with first-episode psychosis: results from the TEA trial. AB - OBJECTIVE: The aim of this study was to compare the effect of quetiapine extended release (ER) versus aripiprazole on corrected QT interval (QTc) and QT dispersion (QTd) in youths with first-episode psychosis. METHODS: Youths 12-17 years were randomized to quetiapine ER (daily dose range = 50 to 800 mg) or aripiprazole (daily dose range = 2.5 to 30 mg) in a 12-week double-blinded trial and examined at weeks 0, 4, and 12. Primary outcome was QTc change using Hodges formula (QTcH); secondary outcomes included QTcH > 450 ms, QTcH > 500 ms, QTcH change > 60 ms, QTd, and heart rate (HR). RESULTS: Among 113 randomized youths, follow-up ECG was available for 93 patients (82.3%) (age = 15.8 +/- 1.3 years, males = 34.4%, schizophrenia = 67.7%). Quetiapine ER treatment (n = 47) was associated with a significant increase in QTcH of + 6.8 +/- 20.2 ms (p = 0.025), while the change from baseline in patients receiving aripiprazole (n = 46) was non significant (- 3.4 +/- 18.9 ms, p = 0.225). One patient in the quetiapine ER group had a QTcH change of + 62.3 ms. Age, sex, smoking, body mass index, and concomitant medication were not significantly associated with QTcH change, but higher baseline potassium was correlated to higher QTcH change in the quetiapine ER group. The HR increased significantly with quetiapine ER (+ 11.0 +/- 14.2 bpm, p < 0.001) but not with aripiprazole (- 0.8 +/- 12.0 bpm, p = 0.643). QTd did not significantly change with quetiapine ER or aripiprazole. CONCLUSION: QTcH and HR increased significantly with quetiapine ER, although changes were small and likely not clinically significant in otherwise healthy patients. QTcH and HR were unchanged with aripiprazole. No significant change in QTd was seen. ClinicalTrials.gov: NCT01119014, EudraCT: 2009-016715-38. PMID- 29185021 TI - Surgical Training and Standardised Management Guidelines Improved the 30-Day Complication Rate After Abdominoplasty for Massive Weight Loss. AB - BACKGROUND: An increasing number of patients need reconstructive surgery after massive weight loss. The hypothesis was that surgical experience together with standardised management guidelines significantly decreases early complication rates after abdominoplasty for massive weight loss. The primary aim was to assess the 30-day complication rate after abdominoplasty following increased surgical training and experience. The secondary aim was to assess whether optimised management guidelines have an impact on the complication rate and patient safety. METHODS: The outcome of 69 consecutive abdominoplasties operated by surgeons in 2011 (Group A) and 70 consecutive patients operated by plastic surgeons in 2010 2012 (Group B) was compared. Another Group of 70 consecutive patients operated by surgeons in 2013-2014 (Group C) was assessed since standardised guidelines for pre- and post-operative treatments and refinement of surgical technique had been introduced. The same surgeons participated in operations of Groups A and C. chi 2 test and Fisher's exact test were applied to dichotomous data. Logistic regression test and ANOVA were used. RESULTS: Group C had more comorbidities and was significantly older. 48 patients in Group A (70%), 31 in Group B (44%) and 13 patients in Group C (19%) had early complications. A significantly decreased rate of complications occurred with improved guidelines and surgical training and experience. (A vs. C p < 0.001 and A vs. B p = 0.008). CONCLUSIONS: Our results indicate that the rate of early complications after abdominoplasty for massive weight loss can be significantly reduced with improved surgical experience and standardised management guidelines.

AB - RATIONALE: The beneficial effects of moderate alcohol may differ in aging men versus women. OBJECTIVES: Cognitive and functional decline and neuropathology were investigated in a cohort of aging men and women with diverse alcohol histories. METHODS: Non-demented (Clinical Dementia Rating (CDR) of <= 0.5 and a Mini-Mental State Examination (MMSE) score of > 24), autonomously living participants were tracked in longitudinal aging studies to examine self-report and objective tests of rates of decline in a cohort (n = 486) of octogenarians. Neurofibrillary tangles (NFTs; Braak stage) and neuritic plaques (NPs) were staged at autopsy in a subset of participants (n = 149) using current standard neuropathologic diagnostic criteria. RESULTS: Moderate drinking men had an attenuated rate of decline compared to rare/never drinkers and women on the MMSE and CDR sum of boxes. In contrast, moderate drinking women had a reduced rate of decline only in the Logical Memory Delayed Recall Test (LMDR) compared to rare/never drinkers and men. Moderate alcohol consumption was associated with a reduction in the incidence of advanced (stages 5-6) Braak NFT stage in men (p < 0.05), with no effect in women. CONCLUSIONS: In this cohort, men experienced a broader range of beneficial effects associated with alcohol. Alcohol's effects may differ in men and women in important ways that suggest a narrower beneficial window. PMID- 29185024 TI - Sirt1 overexpression suppresses fluoride-induced p53 acetylation to alleviate fluoride toxicity in ameloblasts responsible for enamel formation. AB - Low-dose fluoride is an effective caries prophylactic, but high-dose fluoride is an environmental health hazard that causes skeletal and dental fluorosis. Treatments to prevent fluorosis and the molecular pathways responsive to fluoride exposure remain to be elucidated. Previously we showed that fluoride activates SIRT1 as an adaptive response to protect cells. Here, we demonstrate that fluoride induced p53 acetylation (Ac-p53) [Lys379], which is a SIRT1 deacetylation target, in ameloblast-derived LS8 cells in vitro and in enamel organ in vivo. Here we assessed SIRT1 function on fluoride-induced Ac-p53 formation using CRISPR/Cas9-mediated Sirt1 knockout (LS8Sirt/KO) cells or CRISPR/dCas9/SAM-mediated Sirt1 overexpressing (LS8Sirt1/over) cells. NaF (5 mM) induced Ac-p53 formation and increased cell cycle arrest via Cdkn1a/p21 expression in Wild-type (WT) cells. However, fluoride-induced Ac-p53 was suppressed by the SIRT1 activator resveratrol (50 uM). Without fluoride, Ac-p53 persisted in LS8Sirt/KO cells, whereas it decreased in LS8Sirt1/over. Fluoride induced Ac-p53 formation was also suppressed in LS8Sirt1/over cells. Compared to WT cells, fluoride-induced Cdkn1a/p21 expression was elevated in LS8Sirt/KO and these cells were more susceptible to fluoride-induced growth inhibition. In contrast, LS8Sirt1/over cells were significantly more resistant. In addition, fluoride-induced cytochrome-c release and caspase-3 activation were suppressed in LS8Sirt1/over cells. Fluoride induced expression of the DNA double strand break marker gammaH2AX in WT cells and this was augmented in LS8Sirt1/KO cells, but was attenuated in LS8Sirt1/over cells. Our results suggest that SIRT1 deacetylates Ac p53 to mitigate fluoride-induced cell growth inhibition, mitochondrial damage, DNA damage and apoptosis. This is the first report implicating Ac-p53 in fluoride toxicity. PMID- 29185025 TI - Highlight report: gene dose response in N-acetylation capacity. PMID- 29185026 TI - Ballistic impacts on an anatomically correct synthetic skull with a surrogate skin/soft tissue layer. AB - The aim of this work was to further develop a synthetic model of ballistic head injury by the addition of skin and soft tissue layers to an anatomically correct polyurethane skull filled with gelatine 10% by mass. Six head models were impacted with 7.62 x 39 mm full metal jacket mild steel core (FMJ MSC) bullets with a mean velocity of 652 m/s. The impact events were filmed with high-speed cameras. The models were imaged pre- and post-impact using computed tomography. The models were assessed post impact by two experienced Home Office pathologists and the images assessed by an experienced military radiologist. The findings were scored against real injuries. The entry wounds, exit wounds and fracture patterns were scored positively, but the synthetic skin and soft tissue layer was felt to be too extendable. Further work is ongoing to address this. PMID- 29185027 TI - Identification of genes associated with susceptibility to Mycobacterium avium ssp. paratuberculosis (Map) tissue infection in Holstein cattle using gene set enrichment analysis-SNP. AB - Multiple genome-wide association analyses have investigated susceptibility to bovine paratuberculosis, but few loci have been identified across independent cattle populations. A SNP-based gene set enrichment analysis (GSEA-SNP) allows expanded identification of genes with moderate effects on a trait through the enrichment of gene sets instead of identifying only few loci with large effects. Therefore, the objective of this study was to identify genes that were moderately associated with Mycobacterium avium ssp. paratuberculosis (Map) tissue infection using GSEA-SNP in Holstein cattle from the Pacific Northwest (PNW; n = 205) and from the PNW and Northeast (PNW+NE; n = 245) which were previously genotyped with the Illumina BovineSNP50 BeadChip. The GSEA-SNP utilized 4389 gene sets from five databases. For each annotated gene in the UMD3.1 assembly (n = 19,723), the most significant SNP within each gene and its surrounding region (10 kb up- and downstream) was selected as a proxy for that gene. Any gene set with a normalized enrichment score > 2.5 was considered enriched. Thirteen gene sets (8 PNW GSEA SNP; 5 PNW+NE) were enriched in these analyses and all have functions that relate to nuclear factor kappa beta. Nuclear factor kappa beta is critical to gut immune responses, implicated in host immune responses to other mycobacterial diseases, and has established roles in inflammation as well as cancer. Gene sets and genes moderately associated with Map infection could be used in genomic selection to allow producers to select for less susceptible cattle, lower the prevalence of the disease, and reduce economic losses. PMID- 29185029 TI - European status on temporal bone training: a questionnaire study. AB - PURPOSE: In otorhinolaryngology training, introduction to temporal bone surgery through hands-on practice on cadaveric human temporal bones is the gold-standard training method before commencing supervised surgery. During the recent decades, the availability of such specimens and the necessary laboratory facilities for training seems to be decreasing. Alternatives to traditional training can consist of drilling artificial models made of plaster or plastic but also virtual reality (VR) simulation. Nevertheless, the integration and availability of these alternatives into specialist training programs remain unknown. METHODS: We conducted a questionnaire study mapping current status on temporal bone training and included responses from 113 departments from 23 countries throughout Europe. RESULTS: In general, temporal bone training during residency in ORL is organized as in-house training, or as participation in national or international temporal bone courses or some combination hereof. There are considerable differences in the availability of training facilities for temporal bone surgery and the number of drillings each ORL trainee can perform. Cadaveric dissection is still the most commonly used training modality. CONCLUSIONS: VR simulation and artificial models are reported to be used at many leading training departments already. Decreasing availability of cadavers, lower costs of VR simulation and artificial models, in addition to established evidence for a positive effect on the trainees' competency, were reported as the main reasons. Most remaining departments expect to implement VR simulation and artificial models for temporal bone training into their residency programs in the near future. PMID- 29185028 TI - Significant association of the cytokine variants with head and neck cancer risk: evidence from meta-analysis. AB - AIM: To evaluate the possible relevance of the IL-18-137 G>C (rs187238), IL-18 607 C>A (rs1946518) and IL-4-590 C>T (rs2243250) polymorphisms to the genetic susceptibility of head and neck cancer. METHODS: Data were retrieved from PubMed, EMBASE, Web of Science and CNKI databases, and the results were independently analysed by two reviewers using Stata 14.0 software. RESULTS: After searching for and assessing the literature, a total of thirteen studies involving 2,959 patients newly diagnosed as head and neck cancer and 3,622 controls from healthy donors were analysed. The results suggested that a strong relationship between patients and healthy controls was observed in the IL-18-137 G>C polymorphism in consistence with the result (CC vs. GG + GC: OR = 1.63, P = 0.004; CC vs. GG: OR = 1.82, P = 0.001). When stratified by cancer type, ethnicity and the source of control samples, significant and elevated risks were obtained in the genetic susceptibility to Asian patients with NPC in all genetic models and in those studies using the PCR-RFLP test method. In addition, comparable results were obtained for the IL-18-607 C>A polymorphism, especially for Asian patients with NPC. CONCLUSIONS: It should be a potential association between IL-18 variants and nasopharyngeal carcinoma. Furthermore, IL-18 gene variants might be considered as a critical role in predicting the occurrence of nasopharyngeal carcinoma in Asian population. However, the IL-4-590 C>T polymorphism does not influence the development of head and neck cancer. PMID- 29185030 TI - First detection and molecular identification of Entamoeba bovis from Japanese cattle. AB - Thus far, Entamoeba species have been classified based on morphology such as the number of nuclei in mature cysts and their hosts. Using recently developed molecular tools, ruminant Entamoeba spp. are currently classified into four species/genotypes: E. bovis and Entamoeba ribosomal lineages (RL) 1, 2, and 4. However, the distribution or pathogenicity of ruminant Entamoeba has not been well documented. In the present study, we examined a total of 25 fecal and seven environmental samples collected from six farms in Japan from 2016 to 2017 by the floatation method and PCR and sequencing analyses. Consequently, we detected Entamoeba cysts in 18 of 25 cattle samples and four of the seven environmental samples, including soil and drinking water, by microscopic examinations. In sequential examinations, Entamoeba-positive cattle were found to shed cysts without any clinical symptoms for more than 8 months. By PCR for molecular identification, isolates in ten cattle and one soil sample were successfully sequenced and formed a cluster of E. bovis, which was separated from those of other Entamoeba species/genotypes such as RL1-4 in phylogenetic analysis. To our knowledge, this is the first report about E. bovis in Japan, and our results may implicate that E. bovis is not pathogenic. PMID- 29185031 TI - Amplifying and broadening the cytotoxic profile of quercetin in cancer cell lines through bioconjugation. AB - Quercetin is a flavonoid presenting cytotoxicity against different cancer cell lines. We hypothesized that its core could serve as a scaffold for generating more potent compounds. A quercetin-alanine bioconjugate was synthesized, its cellular internalization was monitored through confocal microscopy and its cytotoxic activity was explored against ten different cell lines. The bioconjugate consistently illustrated enhanced cytotoxic activity with respect to the parent compound. A threefold enhancement in its cytotoxicity was revealed for HeLa, A549, MCF-7 and LNCaP cells. In silico studies suggested that quercetin alanine possesses enhanced binding affinity to human estrogen receptor alpha corroborating to its activity to MCF-7, overexpressing this receptor. Spectrofluorimetric, calorimetric and in silico studies revealed that quercetin alanine binds primarily to Sudlow site I of serum albumin mainly through hydrogen bonding. Through this array of experiments we discovered that the specific compound bears a more refined pharmaceutical profile in contrast to quercetin in terms of cytotoxicity, while at the same time preserves its affinity to serum albumin. Natural products could thus offer a potent scaffold to develop bioconjugates with amplified therapeutic window.

AB - A historical overview of peptide chemistry from T. Curtius to E. Fischer to M. Bergmann and L. Zervas is first presented. Next, the fundamentals of peptide synthesis with a focus on solid phase peptide synthesis by R. B. Merrifield are described. Immobilization strategies to attach the first amino acid to the resin, coupling strategies in stepwise peptide chain elongation, and approaches to synthesize difficult peptide sequences are also shown. A brief comparison between tert-butyloxycarbonyl (Boc)/benzyl (Bzl) strategy and 9-fluorenylmethoxycarbonyl (Fmoc)/tert-butyl (t -Bu) strategy utilized in solid phase peptide synthesis is given with an emphasis on the latter. Finally, the review focuses on the discovery and development of peptide ligation and the latest advances in this field including native amide bond formation strategies, these include the native chemical ligation, alpha-ketoacid-hydroxylamine ligation, and serine/threonine ligation which are the most commonly used chemoselective ligation methods that provide amide bond at the ligation site. This review provides an overview of the literature concerning the most important advances in the chemical synthesis of proteins and peptides covering the period from 1882 to 2017. PMID- 29185033 TI - Transcriptomic and proteomic feature of salt stress-regulated network in Jerusalem artichoke (Helianthus tuberosus L.) root based on de novo assembly sequencing analysis. AB - MAIN CONCLUSION: Ribosome activation and sugar metabolic process mainly act on the regulation of salt tolerance in the bioenergy crop Helianthus tuberosus L. as dissected by integrated transcriptomic and proteomic analyses. Helianthus tuberosus L. is an important halophyte plant that can survive in saline-alkali soil. It is vitally necessary to build an available genomic resource to investigate the molecular mechanisms underlying salt tolerance in H. tuberosus. De novo assembly and annotation of transcriptomes were built for H. tuberosus using a HiSeq 4000 platform. 293,823 transcripts were identified and annotated into 190,567 unigenes. In addition, iTRAQ-labeled quantitative proteomics was carried out to detect global protein profiling as a response to salt stress. Comparative omics analysis showed that 5432 genes and 43 proteins were differentially expressed in H. tuberosus under salt stress, which were enriched in the following processes: carbohydrate metabolism, ribosome activation and translation, oxidation-reduction and ion binding. The reprogramming of transcript and protein works suggested that the induced activity of ribosome and sugar signaling may endue H. tuberosus with salt tolerance. With high-quality sequencing and annotation, the obtained transcriptomics and proteomics provide a robust genomic resource for dissecting the regulatory molecular mechanism of H. tuberosus in response to salt stress. PMID- 29185034 TI - Molecular docking simulation on the interactions of laccase from Trametes versicolor with nonylphenol and octylphenol isomers. AB - The biodegradation of nonylphenol (NP) and octylphenol (OP) isomers by laccase has attracted increasing concerns. However, the interaction mechanism between these isomers and laccase remains unclear, especially for fungal laccase. In this work, molecular docking was employed to study this issue. The results indicated that the structural characteristic of alkyl chain (position and branching degree) affected the interactions between Trametes versicolor (T. versicolor) laccase and isomers. The binding affinity between them was closely related to the position and branching degree of alkyl chain in isomers. The binding affinities between linear isomers and T. versicolor laccase were para-position < meta-position < ortho-position. For selected branched 4-NP, the isomers with bulky alpha substituent in alkyl chain had higher binding affinities. In addition, hydrophobic contacts between T. versicolor laccase and NP or OP isomers were necessary, while H-bonds were optional. The isomers with similar structure may have more common residues involved in hydrophobic contacts. The H-bonds of selected NPs and OPs were all connected with phenolic hydroxyl. These findings provide an insight into detailed interaction mechanism between T. versicolor laccase and isomers of NP and OP. It is helpful to broaden the knowledge of degradation technology of NPs and OPs and provide theoretical basis on biological remediation of these contaminants. PMID- 29185035 TI - Relationship Between Frequency of Spontaneous Swallowing and Salivary Substance P Level in Patients with Acute Stroke. AB - The frequency of spontaneous swallowing is useful for screening of dysphagia in acute stroke. Low levels of substance P (SP) in saliva attenuate the swallowing reflex. The aim of this study was to determine the relationship between the frequency of spontaneous swallowing and salivary SP levels. In 40 subjects, saliva was collected within 72 h after stroke onset and salivary SP levels were measured using ELISA kit at a later date. The frequency of spontaneous swallowing was measured over 1 h using a microphone placed on the neck. Pneumonia was diagnosed by the presence of pyrexia and at least two respiratory problems of four categories (sputum, cough or breathing pattern, breath sound, and gas change). The presence of detectable levels of SP in the saliva was confirmed in 17 patients (high SP group), whereas the level was below the detection limit of the ELISA kit in 23 patients (low SP group). The frequency of spontaneous swallowing was significantly lower in low SP group (16.1 +/- 11.6 per hour) than in the high SP group (30.4 +/- 20.4, p = 0.016). As the result of multiple regression analysis, salivary SP levels were correlated with frequency of spontaneous swallowing independently of age, NIHSS, and GCS. The incidence of pneumonia was significantly higher in the low than high SP group (p < 0.001). In conclusion, the frequency of spontaneous swallowing was decreased in acute stroke patients with low salivary SP levels. Salivary SP levels can be potentially a useful biomarker of risk of stroke-associated pneumonia in the acute stage. PMID- 29185046 TI - Functional outcomes after removal of hardware in patellar fracture: are we helping our patients? AB - PURPOSE: Functional outcomes after Open Reduction Internal Fixation (ORIF) of the patella are variable. Common complications of patella ORIF include persistent anterior knee pain, limited range of motion and symptomatic hardware. The purpose of this study was to evaluate if removal of hardware is beneficial to symptomatic patients after patellar fracture fixation. METHODS: Patients who presented to our institution between December 2006 and November 2014 with patella fractures treated with ORIF were eligible for inclusion. Patella ORIF was performed using (1) K-wires (KW) with a tension band construct or (2) Cannulated Screws (CS) with a tension band construct. Radiological analyses included (1) AO classification and (2) measurements of prominent hardware length. Patient medical charts were reviewed for demographic and intraoperative data as well as peri/postoperative complications. All patients completed the SF-12 score, visual analog scale, Kujala score, Lysholm score and questionaries' regarding return to previous activity levels. RESULTS: Forty-seven patients met the inclusion criteria. The average time from fracture fixation to removal of hardware was 15.8 (SD +/- 14.9) months. The mean follow-up was 43.1 (SD +/- 27.1) months. Patella fixation was accomplished using tension band constructs with KW in 28 patients (59.5%) or with CS in 19 patients (40.5%). Patient reported quality of life and pain outcomes improved significantly after removal of hardware (p = 0.001, and p = 0.002 respectively). Functional outcome scores (Kujala and Lysholm) did not improve significantly after hardware removal in the KW or CS groups. Significantly more patients in the KW group returned to pre-injury activity (p = 0.005). CONCLUSIONS: Hardware removal after patella ORIF significantly improves patient reported pain and quality of life outcomes but not functional outcomes. Patients should be counseled regarding the expected outcome of hardware removal following patella ORIF and diabetic patients should be given special consideration before undergoing this procedure. PMID- 29185047 TI - PID temperature controller in pig nursery: spatial characterization of thermal environment. AB - The use of enhanced technologies of temperature control can improve the thermal conditions in environments of livestock facilities. The objective of this study was to evaluate the spatial distribution of the thermal environment variables in a pig nursery with a heating system with two temperature control technologies based on the geostatistical analysis. The following systems were evaluated: overhead electrical resistance with Proportional, Integral, and Derivative (PID) controller and overhead electrical resistance with a thermostat. We evaluated the climatic variables: dry bulb temperature (Tbs), air relative humidity (RH), temperature and humidity index (THI), and enthalpy in the winter, at 7:00, 12:00, and 18:00 h. The spatial distribution of these variables was mapped by kriging. The results showed that the resistance heating system with PID controllers improved the thermal comfort conditions in the pig nursery in the coldest hours, maintaining the spatial distribution of the air temperature more homogeneous in the pen. During the hottest weather, neither system provided comfort. PMID- 29185045 TI - Preoperative chronic kidney disease is predictive of oncological outcome of radical cystectomy for bladder cancer. AB - PURPOSE: To evaluate the impact of preoperative chronic kidney disease (CKD) on oncological outcomes after radical cystectomy (RC) for bladder cancer. METHODS: We reviewed the medical records of patients with urothelial bladder carcinoma who underwent RC with curative intent at seven hospitals between 1990 and 2013. After excluding patients with a history of upper urinary tract urothelial cancer or neoadjuvant chemotherapy, we analyzed 594 cases for the study. Preoperative estimated glomerular filtration rate (eGFR) was calculated using the three variable Japanese equation for GFR estimation from serum creatinine level and age. Patients were divided into four groups of different CKD stages based on eGFR values (mL/min/1.73 m2), i.e., >= 60 (CKD stages G1-2), 45-60 (G3a), 30-45 (G3b), and < 30 (G4-5). Survival was estimated using the Kaplan-Meier method. Univariate and multivariate Cox proportional hazards regression analyses addressed survivals after RC. RESULTS: Median age of patients was 67 years. Patients were classified into CKD stages: G1-2 (n = 388; 65.3%), G3a (n = 122; 20.5%), G3b (n = 51; 8.6%), and G4-5 (n = 33; 5.6%). During a median follow-up of 4.0 years, 200 and 164 patients showed cancer progression and died of bladder cancer, with the 5-year progression-free survival (PFS) and cancer-specific survival (CSS) of 64.9 and 70.2%, respectively. On multivariate analyses, CKD stages of G3b or greater, advanced pT stage, lymph node metastasis, and positive lymphovascular invasion were independent poor prognostic factors for PFS and CSS. CONCLUSIONS: We demonstrated that the advanced preoperative CKD stage was significantly associated with poor oncological outcomes of the bladder cancer after RC. PMID- 29185048 TI - Impaired left ventricular diastolic function is related to the formation of left ventricular apical thrombus in patients with acute anterior myocardial infarction. AB - Left ventricular (LV) apical thrombus is a clinically important complication which can cause systemic embolization in patients with anterior acute myocardial infarction (AMI). Systolic dysfunction has been a risk factor for developing LV apical thrombus in AMI patients. However, the role of diastolic dysfunction in the development of LV apical thrombus in these patients is still unknown. We performed this study to evaluate whether diastolic dysfunction can influence the development of LV apical thrombus in anterior AMI patients. We retrospectively analyzed all consecutive anterior AMI patients with available echocardiographic images within 1 month from January 2005 to April 2016. After gathering clinical characteristics from their medical records, systolic and diastolic functions were analyzed from digitally stored echocardiographic images. We included a total of 1045 patients (748 males, mean age 64 +/- 12 years) with anterior AMI, and 494 (47%) were diagnosed as STEMI. The incidence of LV apical thrombus was 3.3% (34/1045). The LV apical thrombus group had larger LV diastolic dimension, larger LV diastolic and systolic volumes, and lower LVEF than the no LV thrombus group. The LV apical thrombus group showed higher mitral E velocity over mitral annular E' velocity ratio, an indicator of LV end-diastolic pressure (P < 0.001). In the LV apical thrombus group, the incidence of grade 2 diastolic dysfunction (32 vs 12%, P = 0.001) and grade 3 diastolic dysfunction (26 vs 2%, P < 0.001) were significantly higher than in the no LV apical thrombus group. The presence of more than grade 2 diastolic dysfunction, LVEF and presence of LV apical aneurysm were statistically significant factors associated with LV apical thrombus after the multivariate analysis. In conclusion, along with LV systolic dysfunction and LV apical aneurysm, LV diastolic dysfunction was also related with the presence of LV apical thrombus in patients with anterior AMI. PMID- 29185049 TI - A Radial Pillar Device (RAPID) for continuous and high-throughput separation of multi-sized particles. AB - Pillar-based microfluidic sorting devices are preferred for isolation of rare cells due to their simple designs and passive operation. Dead-end pillar filters can efficiently capture large rare cells, such as, circulating tumor cells (CTCs), nucleated red blood cells (NRBCs), CD4 cells in HIV patients, etc., but they get clogged easily. Cross flow filters are preferred for smaller rare particles (e.g. separating bacteria from blood), but they need additional buffer inlets and a large device footprint for efficient operation. We have designed a new microparticle separation device i.e. Ra dial Pi llar D evice (RAPID) that combines the advantages of dead-end and cross flow filters. RAPID can simultaneously isolate both large and small rare particles from a mixed population, while functioning for several hours without clogging. We have achieved simultaneous separation of 10 MU m and 2 MU m polystyrene particles from a mixture of 2 MU m, 7 MU m and 10 MU m particles. RAPID achieved average separation purity and recovery in excess of ~90%. The throughput of our device (~3ml/min) is 10 and 100 times higher compared to cross flow and dead-end filters respectively, thereby justifying the name RAPID. PMID- 29185050 TI - Practically applicable nerve ultrasound models for the diagnosis of axonal and demyelinating hereditary motor and sensory neuropathies (HMSN). AB - PURPOSE: To develop specific diagnostic ultrasound (US) models for hereditary motor and sensory neuropathies (HMSN) in patients with primarily demyelinating or axonal polyneuropathies (PNP) according to standard nerve conduction studies (NCS) criteria. METHODS: Single-centre, examiner-blinded cross-sectional study in acquired PNP (consecutive recruitment strategy) and HMSN patients (convenience sample). Allocation into demyelinating or axonal phenotype via easily applicable NCS criteria. Assessment of single measurements by receiver-operating curve (ROC) analysis, development of diagnostic models based on the best measurement values in ROC. RESULTS: Of 85 enrolled subjects, 53 (62%) had HMSN and 32 (38%) acquired PNPs, and 60 subjects (71%) had demyelinating and 25 (29%) axonal PNP. ROC area under the curve of means of the z-transformed 5 best measurement values was 0.87 for demyelinating and 0.99 for axonal HMSN. Diagnostic models showed high accuracy for both demyelinating (84% sensitivity, 86% specificity) and axonal HMSN (100% sensitivity and specificity). As a measure of variability of morphologic changes, standard deviations of z-transformed measurements were compared for acquired PNP and HMSN. In contrast to previous reports of more homogenous nerve enlargements in HMSN, standard deviations were higher in HMSN than in acquired PNP. Additionally, the performance of previously published models for the diagnosis of HMSN in demyelinating PNP was compared. Previously published models showed lower sensitivities (50-58%), but comparable specificities (91-100%) when applied to NCS-criteria defined demyelinating PNP group. CONCLUSION: Diagnostic ultrasound models for HMSN in patients with demyelinating or axonal neuropathies show high accuracy and can contribute to differential diagnosis in clinical routine. PMID- 29185051 TI - Holography microscopy as an artifact-free alternative to phase-contrast. AB - Artifact-free microscopic images represent a key requirement of multi-parametric image analysis in modern biomedical research. Holography microscopy (HM) is one of the quantitative phase imaging techniques, which has been finding new applications in life science, especially in morphological screening, cell migration, and cancer research. Rather than the classical imaging of absorbing (typically stained) specimens by bright-field microscopy, the information about the light-wave's phase shifts induced by the biological sample is employed for final image reconstruction. In this comparative study, we investigated the usability and the reported advantage of the holography imaging. The claimed halo free imaging was analyzed compared to the widely used Zernike phase-contrast microscopy. The intensity and phase cross-membrane profiles at the periphery of the cell were quantified. The intensity profile for cells in the phase-contrast images suffers from the significant increase in intensity values around the cell border. On the contrary, no distorted profile is present outside the cell membrane in holography images. The gradual increase in phase shift values is present in the internal part of the cell body projection in holography image. This increase may be related to the increase in the cell internal material according to the dry mass theory. Our experimental data proved the halo-free nature of the holography imaging, which is an important prerequisite of the correct thresholding and cell segmentation, nowadays frequently required in high content screening and other image-based analysis. Consequently, HM is a method of choice whenever the image analysis relies on the accurate data on cell boundaries. PMID- 29185054 TI - Vacuum extraction in low birth weight (< 2500 g) neonates. AB - PURPOSE: To evaluate the impact of vacuum extraction on birth injuries among low birth weight neonate (2000-2499 g). METHODS: Retrospective cohort study of women with singleton pregnancies > 34 weeks, birth weight of 2000-3500 g, undergoing vacuum extraction, between 2007 and 2014. Outcomes were compared between neonates who weighed 2000-2499 g and 2500-3500 g. RESULTS: Out of 62,102 deliveries, 5064 (8.2%) met the inclusion criteria, of which 269 (5.3%) neonates were included in the 2000-2499 g group. In this group, gestational age at delivery was lower, the rate of preeclampsia without and with severe features was higher, the rate of induction of labor was higher as was the rate of intermediate/abnormal fetal heart rate tracings as an indication for vacuum extraction (46.2% vs. 28.0%, P < 0.001). No difference was found with regards to birth injuries (2.6% vs. 3.5%, P = 0.44). The rate of composite adverse outcomes other than birth injuries was higher in the 2000-2499 g group (13.0% vs. 9.1%, P = 0.03). Each additional 250 g in birth weight had an increased OR of 1.36 for birth injuries. CONCLUSION: Vacuum extraction of neonates weighing 2000-2499 g seems to be as safe as vacuum extractions of neonates weighing 2500-3500 g in term of birth injuries. PMID- 29185052 TI - Functional status mediates the association between peripheral neuropathy and health-related quality of life in individuals with diabetes. AB - AIMS: To examine differences in health-related quality of life (HRQoL) between patients with and without diabetic peripheral neuropathy (DPN), and whether these differences can be explained by functional deficits. METHODS: This was a cross sectional study of 160 patients with type 2 diabetes mellitus, 80 with DPN and 80 without. Assessments included HRQoL (health utility score derived from EQ-5D-5L), functional status measurements [muscle strength, timed up and go (TUG), five times sit-to-stand (FTSTS), functional reach, body sway velocity] and self reported balance confidence [Activities-specific Balance Confidence (ABC) scale]. RESULTS: Mean utility scores were 0.67 +/- 0.14 and 0.77 +/- 0.16 in patients with and without DPN, respectively (p < 0.001). Patients with DPN had lower great toe extensor strength (6.4 +/- 1.8 vs 7.6 +/- 2.8 lbs, p = 0.001), greater body sway velocity (2.40 +/- 1.31 vs 1.90 +/- 0.52 mm/s, p = 0.002), slower TUG (12.1 +/- 4.6 vs 10.1 +/- 2.3 s, p < 0.001) and FTSTS (15.8 +/- 5.8 vs 13.9 +/- 5.4 s, p = 0.03) scores, and lower ABC score (73.4 +/- 21.3 vs 82.6 +/- 16.9, p = 0.003), compared to those without DPN. On stepwise multiple regression, DPN status, FTSTS, body sway velocity, BMI, diabetes duration, pain, and gender explained 38% of HRQoL variance. Addition of ABC score into the model explained 45% of variance. Results from structural equation modelling showed that DPN had direct effects on HRQoL and indirect effects through FTSTS, body sway velocity, and ABC score, with chi 2 = 8.075 (p = 0.044), root mean square error of approximation = 0.103 (lower bound 0.015, upper bound 0.191), Comparative Fit Index = 0.966, Tucker-Lewis Index = 0.887, and Standardized Root Mean Square Residual = 0.053. CONCLUSIONS: Patients with DPN have worse HRQoL compared to patients without DPN, partly mediated by functional status parameters. Effective interventions targeting functional status may be beneficial in improving HRQoL in these patients. PMID- 29185055 TI - BioGlue(r) induced granuloma causing symptomatic spinal cord compression: a late complication. AB - BioGlue(r) is an inert, bioadhesive surgical substance commonly used in spinal surgery to aid dural closure. The authors describe two cases in which the use of BioGlue(r) caused a local reaction culminating in the formation of a granuloma that caused cord compression several years after surgery in one case in which a second operation was required to relieve cord compression and remove the foreign material. In the other case spontaneous resolution occurred. To our knowledge these are the first reports of delayed spinal cord compression secondary to BioGlue(r)-induced granuloma. We recommend judicious use of this substance. PMID- 29185056 TI - Intramedullary holocord abscess secondary to infected dermoid cyst. AB - In the literature, less than ten cases of holocord intramedullary abscess in children have been described. A 15-month-old girl presented with flaccid paraplegia and dermal sinus in the sacral region. MRI highlighted an infected lumbar dermoid cyst. The child underwent surgery to remove the cyst and purulent collection. Five days after surgery, she developed upper limbs paresis. An MRI showed a holocord abscess. A catheter was inserted through a cervical myelotomy into the abscess for drainage with a good postoperative recovery. A rapid management, even for extended or recurrent intramedullary abscess, can prevent potential severe neurological dysfunctions. PMID- 29185057 TI - Implications of a paediatrician-psychologist tandem for sickle cell disease care and impact on cognitive functioning. AB - : Sickle cell disease (SCD), a life-threatening chronic disease, necessitates a paediatric treatment plan that considers the influence of psychological, family and intercultural factors. At the Louis-Mourier Hospital (APHP) in Colombes, France, we introduced an original paediatric-psychological partnership where a clinical psychologist accompanies the paediatrician at programmed consultations. We evaluated children and their parents treated in Colombes and in two other paediatric units using standardized culture-free tools and clinical interviews to evaluate the psychological repercussions of SCD. We first present a global view of the different ways that SCD affects both children and their families. We then discuss findings from a study evaluating the overall efficacy of an integrated psycho-medical treatment model as compared to the usual medical care model. Children in the integrated care model improved their cognitive functioning assessed using the Rey-Osterrieth complex figure test compared to treatment as usual. CONCLUSION: Findings suggest that the concept of a "partnership practice" can improve children's ability to grapple with SCD and is a promising approach for long-term care of SCD. What is Known: * Painful crises of sickle cell disease are unpredictable and appear in early childhood * Stress as well as the complex psychological and intercultural issues associated with SCD may aggravate the children's symptoms * Standard pediatric care and research deal primarily with medical issues What is New: * Evidence-based research examining the psychological repercussions of SCD in pediatric treatment as well as the parental distress * First study using standardized culture-free tools * Cognitive functioning improves under an innovative "partnership" model. PMID- 29185058 TI - Content-based image retrieval for Lung Nodule Classification Using Texture Features and Learned Distance Metric. AB - Similarity measurement of lung nodules is a critical component in content-based image retrieval (CBIR), which can be useful in differentiating between benign and malignant lung nodules on computer tomography (CT). This paper proposes a new two step CBIR scheme (TSCBIR) for computer-aided diagnosis of lung nodules. Two similarity metrics, semantic relevance and visual similarity, are introduced to measure the similarity of different nodules. The first step is to search for K most similar reference ROIs for each queried ROI with the semantic relevance metric. The second step is to weight each retrieved ROI based on its visual similarity to the queried ROI. The probability is computed to predict the likelihood of the queried ROI depicting a malignant lesion. In order to verify the feasibility of the proposed algorithm, a lung nodule dataset including 366 nodule regions of interest (ROIs) is assembled from LIDC-IDRI lung images on CT scans. Three groups of texture features are implemented to represent a nodule ROI. Our experimental results on the assembled lung nodule dataset show good performance improvement over existing popular classifiers. PMID- 29185061 TI - Electronic structures of elements according to ionization energies. AB - The electronic structures of elements in the periodic table were analyzed using available experimental ionization energies. Two new parameters were defined to carry out the study. The first parameter-apparent nuclear charge (ANC)-quantified the overall charge of the nucleus and inner electrons observed by an outer electron during the ionization process. This parameter was utilized to define a second parameter, which presented the shielding ability of an electron against the nuclear charge. This second parameter-electron shielding effect (ESE) provided an insight into the electronic structure of atoms. This article avoids any sort of approximation, interpolation or extrapolation. First experimental ionization energies were used to obtain the two aforementioned parameters. The second parameter (ESE) was then graphed against the electron number of each element, and was used to read the corresponding electronic structure. The ESE showed spikes/peaks at the end of each electronic shell, providing insight into when an electronic shell closes and a new one starts. The electronic structures of elements in the periodic table were mapped using this methodology. These graphs did not show complete agreement with the previously known "Aufbau" filling rule. A new filling rule was suggested based on the present observations. Finally, a new way to organize elements in the periodic table is suggested. Two earlier topics of effective nuclear charge, and shielding factor were also briefly discussed and compared numerically to demonstrate the capability of the new approach. PMID- 29185060 TI - The CompTox Chemistry Dashboard: a community data resource for environmental chemistry. AB - Despite an abundance of online databases providing access to chemical data, there is increasing demand for high-quality, structure-curated, open data to meet the various needs of the environmental sciences and computational toxicology communities. The U.S. Environmental Protection Agency's (EPA) web-based CompTox Chemistry Dashboard is addressing these needs by integrating diverse types of relevant domain data through a cheminformatics layer, built upon a database of curated substances linked to chemical structures. These data include physicochemical, environmental fate and transport, exposure, usage, in vivo toxicity, and in vitro bioassay data, surfaced through an integration hub with link-outs to additional EPA data and public domain online resources. Batch searching allows for direct chemical identifier (ID) mapping and downloading of multiple data streams in several different formats. This facilitates fast access to available structure, property, toxicity, and bioassay data for collections of chemicals (hundreds to thousands at a time). Advanced search capabilities are available to support, for example, non-targeted analysis and identification of chemicals using mass spectrometry. The contents of the chemistry database, presently containing ~ 760,000 substances, are available as public domain data for download. The chemistry content underpinning the Dashboard has been aggregated over the past 15 years by both manual and auto-curation techniques within EPA's DSSTox project. DSSTox chemical content is subject to strict quality controls to enforce consistency among chemical substance-structure identifiers, as well as list curation review to ensure accurate linkages of DSSTox substances to chemical lists and associated data. The Dashboard, publicly launched in April 2016, has expanded considerably in content and user traffic over the past year. It is continuously evolving with the growth of DSSTox into high-interest or data rich domains of interest to EPA, such as chemicals on the Toxic Substances Control Act listing, while providing the user community with a flexible and dynamic web-based platform for integration, processing, visualization and delivery of data and resources. The Dashboard provides support for a broad array of research and regulatory programs across the worldwide community of toxicologists and environmental scientists. PMID- 29185059 TI - Aerobic but not Resistance Exercise Can Induce Inflammatory Pathways via Toll Like 2 and 4: a Systematic Review. AB - BACKGROUND: Only a few studies have addressed the relationship between toll-like receptors 2 and 4 (TLR2 and TLR4) and the production of local and systemic cytokines in response to physical exercise, and they have produced conflicting results. We aimed to determine whether acute and chronic exercise outcomes are associated with changes in TLR2 and TLR4 expression and signaling and if so, the mechanisms that connect them. METHODS: PubMed database were consulted. This systematic review selected 39 articles, 26 involving humans and 13 based on rodents. RESULTS: In acute resistance exercise studies, 75% reported a decrease in TLR4 or TLR2 expression and 25% did not find differences. For chronic resistance exercise studies, 67% reported a reduction of expression and 33% did not find differences. Studies of both types reported reductions in pro inflammatory cytokines. In acute aerobic exercise studies, 40% revealed a decline in the expression of the receptors, 7% reported no significant difference, 40% showed an increase, and 13% did not evaluate their expression. Fifty-eight percent of studies of chronic aerobic exercise revealed a reduction in expression, 17% did not find a difference, and 25% reported increases; they also suggested that the expression of the receptors might be correlated with that of inflammatory cytokines. In studies on combined exercise, 50% reported a decline in receptors expression and 50% did not find a difference. CONCLUSIONS: The majority of the articles (54%) link different types of exercise to a decline in TLR4 and TLR2 expression. However, aerobic exercise may induce inflammations through its influence on these receptor pathways. Higher levels of inflammation were seen in acute sessions (40%) than regular sessions (25%).

PMID- 29185064 TI - The effect of hair removal after surgery for sacrococcygeal pilonidal sinus disease: a systematic review of the literature. AB - BACKGROUND: It has been suggested that removal of body hair in the sacrococcygeal area prevents recurrence after surgery for sacrococcygeal pilonidal sinus disease (SPSD). The aim of this study was to review the literature regarding the effect of hair depilation on the recurrence rate in patients surgically treated for SPSD. METHODS: A systematic search was performed in PubMed, EMBASE, and The Cochrane Library by using synonyms for SPSD. Title, abstract, and full text were screened by two independent reviewers. Data were systematically collected from all included studies by using a standardized data extraction form. RESULTS: The search and selection yielded 14 studies, involving 963 patients. The study design of the included studies was: retrospective cohort (n = 7), prospective cohort (n = 3), randomized controlled trial (n = 2), and case-control (n = 2).The mean length of follow-up was 37.0 (standard error of the mean: 35.0) months. The recurrence rate was 9.3% (34 out of 366 patients) in patients who had laser hair removal, 23.4% (36 out of 154 patients) in those who had razor shaving/cream depilation, and 19.7% (85 out of 431 patients) in those who had no hair removal after surgery for SPSD. CONCLUSIONS: This systematic review showed a lower recurrence rate after laser hair removal compared to no hair removal and razor/cream depilation. Due to the small sample size and limited methodological quality of the included studies, a high-quality randomized controlled trial is required. PMID- 29185062 TI - Early Recognition and Treatment Heralds Optimal Outcomes: the Benefits of Combined Rheumatology-Dermatology Clinics and Integrative Care of Psoriasis and Psoriatic Arthritis Patients. AB - PURPOSE OF REVIEW: Diagnosis and treatment of psoriatic arthritis (PsA) can be challenging and require a multidisciplinary approach. This review provides an overview of combined dermatology-rheumatology clinics. RECENT FINDINGS: Combined dermatology-rheumatology clinics have emerged to optimize integrated care for patients with psoriasis and PsA. There are over 20 such clinics across the USA. These clinics facilitate multidisciplinary care for patients with psoriasis and PsA and have been found to improve outcomes and enhance both patient and physician satisfaction and knowledge. Challenges presented by these clinics include appropriate scheduling for both dermatologists and rheumatologists and proving the benefits of the clinics to obtain institutional support. Combined dermatology-rheumatology clinics are a novel model of care for patients with psoriasis and PsA. They improve outcomes, patient and physician satisfaction, and efficiency. As more of these clinics are established, we must further understand their impact on outcomes and care processes. PMID- 29185065 TI - Consensus queries in ligand-based virtual screening experiments. AB - BACKGROUND: In ligand-based virtual screening experiments, a known active ligand is used in similarity searches to find putative active compounds for the same protein target. When there are several known active molecules, screening using all of them is more powerful than screening using a single ligand. A consensus query can be created by either screening serially with different ligands before merging the obtained similarity scores, or by combining the molecular descriptors (i.e. chemical fingerprints) of those ligands. RESULTS: We report on the discriminative power and speed of several consensus methods, on two datasets only made of experimentally verified molecules. The two datasets contain a total of 19 protein targets, 3776 known active and ~ 2 * 106 inactive molecules. Three chemical fingerprints are investigated: MACCS 166 bits, ECFP4 2048 bits and an unfolded version of MOLPRINT2D. Four different consensus policies and five consensus sizes were benchmarked. CONCLUSIONS: The best consensus method is to rank candidate molecules using the maximum score obtained by each candidate molecule versus all known actives. When the number of actives used is small, the same screening performance can be approached by a consensus fingerprint. However, if the computational exploration of the chemical space is limited by speed (i.e. throughput), a consensus fingerprint allows to outperform this consensus of scores. PMID- 29185066 TI - Electronic structure and bonding of the dinuclear metal M2(CO)10 decacarbonyls: applications of natural orbitals for chemical valence. AB - The nature of the chemical metal-metal bond in M2(CO)10 (M = Mn, Re, Tc) dinuclear decacarbonyls complexes was investigated for the first time using the natural orbital chemical valence (NOCV) approach combined with the extended transition state (ETS) for energy decomposition analysis (EDA). The optimized geometries carried out at different levels of theory BP86, BLYP, BLYPD and BP86D, showed that the latter method, i.e., BP86D, led to the best agreement with X-ray experimental measurements. The BP86D/TZP results revealed that the computed covalent contribution to the metal-metal bond are 60.5%, 54.1% and 52.0% for Mn Mn, Re-Re and Tc-Tc, respectively. The computed total interaction energies resulting from attractive terms (DeltaE orb and DeltaE eles), correspond well to experimental predictions, based on bond lengths and energy interaction analysis for the studied complexes. PMID- 29185068 TI - Armed for destruction: formation, function and trafficking of neutrophil granules. AB - Neutrophils respond nearly instantly to infection, rapidly deploying a potent enzymatic and chemical arsenal immediately upon entering an infected site. This capacity for rapid and potent responses is endowed by stores of antimicrobial proteins contained in readily mobilizable granules. These granules contain the proteins necessary to mediate the recruitment, chemotaxis, antimicrobial function and NET formation of neutrophils. Four granule types exist, and are sequentially deployed as neutrophils enter infected sites. Secretory vesicles are released first, enabling recruitment of neutrophils out of the blood. Next, specific and gelatinase granules are released to enable neutrophil migration and begin the formation of an antimicrobial environment. Finally, azurophilic granules release potent antimicrobial proteins at the site of infection and into phagosomes. The step-wise mobilization of these granules is regulated by calcium signaling, while specific trafficking regulators and membrane fusion complexes ensure the delivery of granules to the correct subcellular site. In this review, we describe neutrophil granules from their formation through to their deployment at the site of infection, focusing on recent developments in our understanding of the signaling pathways and vesicular trafficking mechanisms which mediate neutrophil degranulation. PMID- 29185067 TI - Phantom validation of quantitative Y-90 PET/CT-based dosimetry in liver radioembolization. AB - BACKGROUND: PET/CT has recently been shown to be a viable alternative to traditional post-infusion imaging methods providing good quality images of 90Y laden microspheres after selective internal radiation therapy (SIRT). In the present paper, first we assessed the quantitative accuracy of 90Y-PET using an anthropomorphic phantom provided with lungs, liver, spine, and a cylindrical homemade lesion located into the hepatic compartment. Then, we explored the accuracy of different computational approaches on dose calculation, including (I) direct Monte Carlo radiation transport using Raydose, (II) Kernel convolution using Philips Stratos, (III) local deposition algorithm, (IV) Monte Carlo technique (MCNP) considering a uniform activity distribution, and (V) MIRD (Medical Internal Radiation Dose) analytical approach. Finally, calculated absorbed doses were compared with those obtained performing measurements with LiF:Mg,Cu,P TLD chips in a liquid environment. RESULTS: Our results indicate that despite 90Y-PET being likely to provide high-resolution images, the 90Y low branch ratio, along with other image-degrading factors, may produce non-uniform activity maps, even in the presence of uniform activity. A systematic underestimation of the recovered activity, both for the tumor insert and for the liver background, was found. This is particularly true if no partial volume correction is applied through recovery coefficients. All dose algorithms performed well, the worst case scenario providing an agreement between absorbed dose evaluations within 20%. Average absorbed doses determined with the local deposition method are in excellent agreement with those obtained using the MIRD and the kernel-convolution dose calculation approach. Finally, absorbed dose assessed with MC codes are in good agreement with those obtained using TLD in liquid solution, thus confirming the soundness of both calculation approaches. This is especially true for Raydose, which provided an absorbed dose value within 3% of the measured dose, well within the stated uncertainties. CONCLUSIONS: Patient-specific dosimetry is possible even in a scenario with low true coincidences and high random fraction, as in 90Y-PET imaging, granted that accurate absolute PET calibration is performed and acquisition times are sufficiently long. Despite Monte Carlo calculations seeming to outperform all dose estimation algorithms, our data provide a strong argument for encouraging the use of the local deposition algorithm for routine 90Y dosimetry based on PET/CT imaging, due to its simplicity of implementation. PMID- 29185069 TI - Connexin 43 and ATP-sensitive potassium channels crosstalk: a missing link in hypoxia/ischemia stress. AB - Connexin 43 (Cx43) is a gap junction protein expressed in various tissues and organs of vertebrates. Besides functioning as a gap junction, Cx43 also regulates diverse cellular processes like cell growth and differentiation, cell migration, cell survival, etc. Cx43 is critical for normal cardiac functioning and is therefore abundantly expressed in cardiomyocytes. On the other hand, ATP sensitive potassium (KATP) channels are metabolic sensors converting metabolic changes into electrical activity. These channels are important in maintaining the neurotransmitter release, smooth muscle relaxation, cardiac action potential repolarization, normal physiology of cellular repolarization, insulin secretion and immune function. Cx43 and KATP channels are part of the same signaling pathway, regulating cell survival during stress conditions and ischemia/hypoxia preconditioning. However, the underlying molecular mechanism for their combined role in ischemia/hypoxia preconditioning is largely unknown. The current review focuses on understanding the molecular mechanism responsible for the coordinated role of Cx43 and KATP channel protein in protecting cardiomyocytes against ischemia/hypoxia stress. PMID- 29185071 TI - Review: adult neurogenesis contributes to hippocampal plasticity. AB - Adult hippocampal neurogenesis is the process by which new functional neurons are added to the adult dentate gyrus of the hippocampus. Animal studies have shown that the degree of adult hippocampal neurogenesis is regulated by local environmental cues as well as neural network activities. Furthermore, accumulating evidence has suggested that adult hippocampal neurogenesis plays prominent roles in hippocampus-dependent brain functions. In this review, we summarize the mechanisms underlying the regulation of adult hippocampal neurogenesis at various developmental stages and propose how adult-born neurons contribute to structural and functional hippocampal plasticity. PMID- 29185070 TI - Single-cell analysis of diversity in human stem cell-derived neurons. AB - Neural stem and progenitor cells produce one of the most remarkable organs in nature, the human brain. Among neural stem cell progeny, post-mitotic neurons are likewise remarkably diverse. Single-cell transcriptomic approaches are now cataloging a long-sought-after molecular taxonomy of neuronal diversity in the brain. Contemporary single-cell omic classifications of neuronal diversity build from electrophysiological approaches that for decades have measured and cataloged diverse biophysical properties of single neurons. With the widespread application of human pluripotent stem cell-based models of neurogenesis to investigate disease pathology and to develop new drugs, a high-resolution understanding of neuronal diversity in vivo is essential to benchmark the state of in vitro models of human neurological disease. PMID- 29185072 TI - In vivo models of alpha-synuclein transmission and propagation. AB - The abnormal accumulation of alpha-synuclein aggregates in neurons, nerve fibers, or glial cells is the hallmark of a group of neurodegenerative diseases known collectively as alpha-synucleinopathies. Clinical, neuropathological, and experimental evidence strongly suggests that alpha-synuclein plays a role not only as a trigger of pathological processes at disease inception, but also as a mediator of pathological spreading during disease progression. Specific properties of alpha-synuclein, such as its ability to pass from one neuron to another, its tendency to aggregate, and its potential to generate self propagating species, have been described and elucidated in animal models and may contribute to the relentless exacerbation of Parkinson's disease pathology in patients. Animal models used for studying alpha-synuclein accumulation, aggregation, and propagation are mostly based on three approaches: (1) intra parenchymal inoculations of exogenous alpha-synuclein (e.g., synthetic alpha synuclein fibrils), (2) transgenic mice, and (3) animals (mice or rats) in which alpha-synuclein overexpression is induced by viral vector injections. Whereas pathological alpha-synuclein changes are consistently observed in these models, important differences are also found. In particular, pronounced pathology in transgenic mice and viral vector-injected animals does not appear to involve self propagating alpha-synuclein species. A critical discussion of these models reveals their strengths and limitations and provides the basis for recommendations concerning their use for future investigations. PMID- 29185074 TI - Evaluating the longevity of surgically extracted Xenopus laevis oocytes for the study of nematode ligand-gated ion channels. AB - Xenopus laevis oocytes have been extensively used as a heterologous expression system for the study of ion channels. While used successfully worldwide as tool for expressing and characterizing ion channels from a wide range of species, the limited longevity of oocytes once removed from the animal can pose significant challenges. In this study, we evaluate a simple and useful method that extends the longevity of Xenopus oocytes after removal from the animal and quantitatively assessed the reliability of the electrophysiological date obtained. The receptor used for this study was the UNC-49 receptor originally isolated from the sheep parasite, Haemonchus contortus. Overall, we found that immediate storage of the ovary in supplemented ND96 storage buffer at 4 degrees C could extend their use for up to 17 days with almost 80% providing reliable electrophysiological data. This means that a single extraction can provide at least 3 weeks of experiments. In addition, we examined 24-day-old oocytes (week 4) extracted from a single frog and also obtained reliable data using the same approach. However, 50% of these oocytes were usable for full dose-response experiments. Overall, we did find that this method has the potential to significantly extend the use of single oocyte extractions for two-electrode voltage clamp electrophysiology. PMID- 29185073 TI - Computational systems biology approaches for Parkinson's disease. AB - Parkinson's disease (PD) is a prime example of a complex and heterogeneous disorder, characterized by multifaceted and varied motor- and non-motor symptoms and different possible interplays of genetic and environmental risk factors. While investigations of individual PD-causing mutations and risk factors in isolation are providing important insights to improve our understanding of the molecular mechanisms behind PD, there is a growing consensus that a more complete understanding of these mechanisms will require an integrative modeling of multifactorial disease-associated perturbations in molecular networks. Identifying and interpreting the combinatorial effects of multiple PD-associated molecular changes may pave the way towards an earlier and reliable diagnosis and more effective therapeutic interventions. This review provides an overview of computational systems biology approaches developed in recent years to study multifactorial molecular alterations in complex disorders, with a focus on PD research applications. Strengths and weaknesses of different cellular pathway and network analyses, and multivariate machine learning techniques for investigating PD-related omics data are discussed, and strategies proposed to exploit the synergies of multiple biological knowledge and data sources. A final outlook provides an overview of specific challenges and possible next steps for translating systems biology findings in PD to new omics-based diagnostic tools and targeted, drug-based therapeutic approaches. PMID- 29185075 TI - Techniques for the collection, transportation, and isolation of orchid endophytes from afar: a case study from Madagascar. AB - BACKGROUND: Tropical orchids need more study with respect to their mycorrhizal associations. For researchers in distant countries who aspire to study these orchids augmenting their conservation, the great distances involved, coupled with limited funds, pose formidable challenges. These challenges are sometimes exacerbated by political unrest, delays in securing permits, unexpected hardships, and the risk that the biological samples collected (e.g., roots harboring mycorrhizal fungi) will not survive long-distance transport. RESULTS: We describe a protocol for the collection and transport of root samples from Madagascar orchids to labs in the United Kingdom (Kew) and the United States (Illinois) where Rhizoctonia-like fungi were subsequently isolated. Three separate trips were made spanning 4 years (2012-2015), with emphasis on the collection of roots from epiphytic, lithophytic, and terrestrial orchids inhabiting the Itremo Massif of the Central Highlands. Collectively, the trips to Madagascar resulted in the isolation of all major groups of Rhizoctonia-like fungi (Ceratobasidium, Tulasnella, Sebacina) from all three orchid growth forms (terrestrials, epiphytes and lithophytes). Sampling of terrestrial and epiphytes during the rainy season (January) yielded best results. CONCLUSIONS: Our study demonstrates that peloton-forming fungi in root samples can retain viability up to 3 weeks after collection.

AB - Individuals with chronic tic disorders (CTDs) frequently describe aversive subjective sensory sensations that precede their tics. The first aim of the present study was to explore the psychometric properties of a standardized self report measure to assess premonitory urges in CTDs, The Premonitory Urge for Tics Scale (PUTS), by replicating the analyses of Woods et al. (J Dev Behav Pediatr 26:397-403, 2005) using a sample twice the size of theirs. The second aim was to conduct an exploratory factor analysis of the PUTS. Eighty-four youth with CTDs, recruited from a pediatric OCD and tic specialty clinic, completed the PUTS while their caregivers completed The Parent Tic Questionnaire (PTQ) and a demographic measure. Consistent with (Woods et al. J Dev Behav Pediatr 26:397-403, 2005), the PUTS was found to be internally consistent (alpha = 0.82) and significantly correlated with overall tic severity as measured by the PTQ (r = 0.24, p < 0.05) as well as the PTQ number (r = 0.34, p < 0.01) and intensity (r = 0.24, p < 0.05) subscales. A factor-analysis of the PUTS revealed a two-factor solution with one factor capturing the quality of premonitory sensations while the other factor assessed the overall intensity of the urges. These results support the use of the PUTS in reliably measuring premonitory urges, particularly in children over the age of 10 years. Additionally, these findings highlight that urges are uniformly reported across gender and age and are more closely associated with number of tics than the frequency or intensity of tics. PMID- 29185078 TI - Evaluation of autonomic functions of patients with multiple system atrophy and Parkinson's disease by head-up tilt test. AB - The aim of this study was to evaluate the autonomic neural function in Parkinson's disease (PD) and multiple system atrophy (MSA) with head-up tilt test and spectral analysis of cardiovascular parameters. This study included 15 patients with MSA, 15 patients with PD, and 29 healthy control (HC) subjects. High frequency power of the RR interval (RR-HF), the ratio of low frequency power of RR interval to RR-HF (RR-LF/HF) and LF power of systolic BP were used to evaluate parasympathetic, cardiac sympathetic and vasomotor sympathetic functions, respectively. Both patients with PD and MSA showed orthostatic hypotension and lower parasympathetic function (RR-HF) at tilt position as compared to HC subjects. Cardiac sympathetic function (RR-LF/HF) was significantly high in patients with PD than MSA at supine position. RR-LF/HF tended to increase in MSA and HC, but decreased in PD by tilting. Consequently, the change of the ratio due to tilting (DeltaRR-LF/HF) was significantly lower in patients with PD than in HC subjects. Further analysis showed that compared to mild stage of PD, RR-LF/HF at the supine position was significantly higher in advanced stage. By tilting, it was increased in mild stage and decreased in the advanced stage of PD, causing DeltaRR-LF/HF to decrease significantly in the advanced stage. Thus, we demonstrated that spectral analysis of cardiovascular parameters is useful to identify sympathetic and parasympathetic disorders in MSA and PD. High cardiac sympathetic function at the supine position, and its reduction by tilting might be a characteristic feature of PD, especially in the advanced stage. PMID- 29185079 TI - Gender Moderates the Association of Depressive Symptoms to Sexual Risk Behavior Among HIV-Positive African-American Outpatients. AB - Previous research has reported an association between depressive symptoms and sexual risk behavior. The purpose of this study was to explore whether gender moderates this association in a sample of HIV-positive African-Americans. Participants (N = 93) self-reported depressive symptoms (Center for Epidemiological Studies-Depression Scale; CES-D), and sexual risk behavior for the past 4 months. Analyses revealed that the depressive symptoms-by-gender interaction was associated with condomless sex and substance use proximal to sex. When analyses were stratified by gender, depressive symptoms were associated with condomless sex and frequency of substance use only for women. We conclude that depressive symptoms may be a more powerful sexual risk factor among women relative to men. PMID- 29185080 TI - Manganese and cobalt recovery by surface display of metal binding peptide on various loops of OmpC in Escherichia coli. AB - In a cell-surface display (CSD) system, successful display of a protein or peptide is highly dependent on the anchoring motif and the position of the display in that anchoring motif. In this study, a recombinant bacterial CSD system for manganese (Mn) and cobalt (Co) recovery was developed by employing OmpC as an anchoring motif on three different external loops. A portion of Cap43 protein (TRSRSHTSEG)3 was employed as a manganese and cobalt binding peptide (MCBP), which was fused with OmpC at three different external loops. The fusions were made at the loop 2 [fusion protein-2 (FP2)], loop 6 (FP6), and loop 8 (FP8) of OmpC, respectively. The efficacy of the three recombinant strains in the recovery of Mn and Co was evaluated by varying the concentration of the respective metal. Molecular modeling studies showed that the short trimeric repeats of peptide probably form a secondary structure with OmpC, thereby giving rise to a difference in metal recovery among the three recombinant strains. Among the three recombinant strains, FP6 showed increased metal recovery with both Mn and Co, at 1235.14 (1 mM) and 379.68 (0.2 mM) umol/g dry cell weight (DCW), respectively. PMID- 29185081 TI - Effect of temperature on diapause termination and post-diapause development in Eotetranychus smithi (Acari: Tetranychidae). AB - Previous studies on the spider mite Eotetranychus smithi Pritchard & Baker have shown that diapause in eggs is induced by low temperature alone and that females developed at <= 17.5 degrees C laid diapause eggs, regardless of the photoperiod. In this study, diapause eggs were kept at 5 degrees C and a photoperiod of 16L:8D for 0-120 days and then maintained at 25 degrees C to know the effect of chilling on diapause termination. Diapause eggs mostly hatched when they were maintained at 25 degrees C after chilling for 30-90 days at 5 degrees C, which suggests that diapause termination is favored by low temperatures. To clarify the hatching conditions after diapause termination, diapause eggs kept at 5 degrees C for 45 days were subsequently maintained at various constant temperatures (from 15 to 25 degrees C) under a long-day photoperiod (16L:8D). The hatchability at all temperatures tested was high (> 90%) and did not significantly differ among the high temperatures. Duration of embryonic development was shorter with increasing warming temperature after chilling. The lower thermal threshold (t) and thermal constant (k) for post-diapause egg development were 10.5 degrees C and 76.9 degree-days, respectively. Females, which developed from diapause eggs that were chilled at 5 degrees C for 45 days and then maintained at 15 degrees C, laid only non-diapause eggs, which indicates that they were prevented from re-entering diapause even under diapause inducing conditions (15 degrees C). Thus, temperature is the main factor to control diapause termination and post-diapause development, which has also been found for other spider mites that enter diapause at the egg stage. PMID- 29185082 TI - Multi-energy spectral CT: adding value in emergency body imaging. AB - Most vendors offer scanners capable of dual- or multi-energy computed tomography (CT) imaging. Advantages of multi-energy CT scanning include superior tissue characterization, detection of subtle iodine uptake differences, and opportunities to reduce contrast dose. However, utilization of this technology in the emergency department (ED) remains low. The purpose of this pictorial essay is to illustrate the value of multi-energy CT scanning in emergency body imaging. PMID- 29185083 TI - Linear ubiquitin chain induces apoptosis and inhibits tumor growth. AB - Ubiquitination of proliferating cell nuclear antigen (PCNA) plays an important role in DNA damage response. Ectopic expression of PCNA fused at either terminus with ubiquitin (Ub) lacking two C-terminal glycine residues induces translesion DNA synthesis which resembles synthesis mediated by PCNA monoubiquitination. PCNA fused with Ub containing the C-terminal Gly residues at the C-terminus can be further polyubiquitinated in a Gly-dependent manner, which inhibits cell proliferation and induces ATR-dependent replication checkpoint. In this study, we surprisingly found that PCNA fused to a head-to-tail linear Ub chain induces apoptosis in a Ub chain length-dependent manner. Further investigation revealed that the apoptotic effect is actually induced by the linear Ub chain independently from PCNA, as the Ub chain fused to GFP or an epitope tag still efficiently induces apoptosis. It is revealed that the artificial linear Ub chain differs from endogenously encoded linear Ub chains in that its Ubs contain a Ub G76S substitution, making the Ub chain resistant to cleavage by deubiquitination enzymes. We demonstrated in this study that ectopic expression of the artificial Ub chain alone in cultured human cancer cells is sufficient to inhibit tumor growth in a xenograft mouse model, making the linear Ub chain a putative anti cancer agent. PMID- 29185084 TI - A triazole-conjugated benzoxazone induces reactive oxygen species and promotes autophagic apoptosis in human lung cancer cells. AB - Numerous approaches suggested that compounds with conjugated triazole moieties or benzoxazone pharmacores are effective to antagonize proliferation of human tumors. The current study reported that a synthetic triazole-conjugated benzoxazone, 4-((5-benzyl-1H-1,2,3-triazol-3-yl)-methyl)-7-methoxy-2H benzo[b][1,4]-oxazin-3(4H)-one (BTO), inhibited growth rates of human non-small cell lung cancer cells. The cytotoxicity can be enhanced with increasing drug concentrations. More evidence supported that the induced reactive oxygen species lead to ultimate apoptotic cell death by recruiting autophagy. The mechanistic pathway as elucidated involved tumor suppressor p53 activation and LC3-1 conversion followed by PARP and procaspase-3 cleavage. Autophagy inhibition reverted apoptotic death and restored cell viabilities. BTO suppressed the development of A549 cell xenograft tumors by activating autophagy and apoptosis simultaneously. As an efficient tumor growth inhibitor with relatively small molecular weight, BTO is a viable addition to the existing list of lung cancer treatment. PMID- 29185085 TI - Addressing comorbidities in psoriatic disease. AB - Psoriasis and PsA are associated with comorbidities including cardiovascular disease, obesity, metabolic syndrome and depression. The purpose of this study was to examine if patients recognize that they are being monitored for comorbidities associated with their condition, and to determine which physicians are managing these comorbidities. Patients with psoriasis without arthritis (PsC) and patients with PsA were recruited from the University of Toronto Psoriasis Cohort and Psoriatic Arthritis Clinic, respectively. A comorbidity questionnaire was developed through a literature review and patients completed the questionnaire at clinic visits or over the telephone. PsA patient responses were compared with information recorded by physicians at clinic visits. A total of 268 patients (103 PsC and 164 PsA) were included. Patients indicated having their blood pressure (96.3%), weight (94.4%), blood sugar (75%) and cholesterol (79.5%) levels checked, with PsA patients indicating being checked more frequently than PsC patients. PsA patients were most uncertain about whether their blood sugar and cholesterol levels were checked by physicians. The highest correlation between patient responses and physician records occurred for medications for diabetes, depression and hypercholesterolemia. Patients indicated their family physician were most responsible in monitoring the comorbidities. Overall, patients documented being moderately well screened for most comorbidities and were most unsure about having their blood sugar and cholesterol levels monitored. Patient education and records should be improved at clinic visits, as there are discrepancies between patient responses and physician records regarding the presence and treatment of comorbidities. PMID- 29185086 TI - Interstitial lung disease in South Africans with systemic sclerosis. AB - To investigate the frequency, severity and predictors of interstitial lung disease (ILD) in a cohort of South Africans with systemic sclerosis (SSc). Retrospective record review of SSc patients attending a tertiary Connective Tissue Diseases Clinic. Patients with ILD, defined by a combination of clinical findings, imaging, and lung function tests were compared to patients without ILD in terms of demographics, clinical features and autoantibodies. The majority (86.8%) of the 151 patients included were of Black ethnicity, 40% had ILD, of whom 39% had moderate-severe lung disease. Univariate predictors of ILD included: disease duration (OR 1.08, 95% CI 1.01-1.15); cough (OR 2.93, 95% CI 1.37-6.29); dyspnoea (OR 2.44, 95% CI 1.23-4.87); bibasal crackles (OR 7.58, 95% CI 3.31 17.37); diffuse cutaneous SSc (dcSSc) (OR 4.55, 95% CI 2.10-9.86) and a speckled anti-nuclear antibody (ANA) pattern (OR 2.47, 95% CI 1.25-4.90). Conversely, limited cutaneous disease (OR 0.22, 95% CI 0.09-0.50) and anti-centromere antibody (ACA) (OR 0.12, 95% CI 0.02-0.97) were protective. Independent predictors of ILD on multivariate analysis were bibasal crackles (OR 9.43, 95% CI 3.25-27.39), disease duration (OR 1.19, 95% CI 1.09-1.30) and speckled ANA (OR 2.95, 95% CI 1.22-7.15). Almost all (86.4%) patients received immunosuppressive treatment and the leading cause of death was related to ILD itself (44.4%). In this cohort of predominantly Black South Africans, SSc ILD was common and carried a poor prognosis. ILD occurred mainly, but not exclusively, in patients with dcSSc, especially those with a speckled ANA pattern. Conversely, the presence of ACA was protective against ILD.

PMID- 29185087 TI - Assistive devices: an effective strategy in non-pharmacological treatment for hand osteoarthritis-randomized clinical trial. AB - : This study aims to evaluate the use of assistive devices as a strategy in non pharmacological treatment for hand osteoarthritis (HOA). This is a randomized, prospective, parallel, assessor-blinded clinical trial, in which patients with a diagnosis of HOA were randomly allocated to an intervention group (IG), where they received assistive devices for daily life activities, or to a control group (CG), where they received a guideline leaflet with information on joint protection and disease features. The primary outcomes considered were occupational performance, measured by the Canadian Occupational Performance Measure (COPM), and hand function was evaluated through the Score for the Assessment and Quantification of Chronic Rheumatoid Affections of the Hands (SACRAH). The secondary outcomes were pain, measured by the visual analog scale (VAS), and quality of life, measured by the World Health Organization Quality of Life Instrument, Short Form (WHOQOL-BREF). We compared both outcomes before and after interventions and outcomes between groups. Participants from the two groups were assessed at the time of inclusion in the study, 30, and 90 days after initial evaluation. Out of the 39 patients included, 19 were allocated to the IG and 20 to the CG. Only two patients from the CG did not complete the follow-up period. The patients' hand function and occupational performance improved after intervention (30 days-SACRAH-p < 0.05; COPM-p < 0.05; VAS-p < 0.05). When comparing results between the groups, there was a statistical difference in COPM (performance-p < 0.001; and satisfaction-p < 0.001), in the first reevaluation carried out. The use of assistive devices has proved to be an effective alternative in non-pharmacological treatment for HOA. CLINICAL TRIAL REGISTRATION: NCT02667145. PMID- 29185089 TI - Pharmacoeconomic evaluation of micafungin versus caspofungin as definitive therapy for candidaemia and invasive candidiasis (IC) in Turkey. AB - Micafungin was shown to be as efficacious as caspofungin in treating patients with candidaemia and invasive candidiasis (IC). However, it remains unknown if micafungin or caspofungin is a cost-effective definitive therapy for candidaemia and IC in Turkey. The present study aimed to determine the economic impact of using micafungin versus caspofungin for treatment of candidaemia and IC in the Turkish setting. A decision analytic model was constructed and was populated with data (i.e. transition probabilities, duration of initial antifungal treatment, reasons for treatment failure, percentage of patients who stepped down to oral fluconazole, and duration on oral fluconazole) obtained from a published randomised clinical trial. Cost inputs were derived from the latest Turkish resources while data that were not readily available in the literature were estimated by expert panels. One-way sensitivity analyses, threshold analyses, scenario analyses and probabilistic sensitivity analyses were conducted. Caspofungin (?2693) incurred a lower total cost than micafungin (?4422), with a net cost saving of ?1729 per treated patient. Drug acquisition cost was the main cost driver for both study arms. The model outcome was robust over wide variations (of +/-100.0% from the base case value) for all input parameters except for micafungin drug cost and the duration of initial treatment with micafungin. Caspofungin appears to be a cost-saving option in treating candidaemia and IC from the Turkish hospital perspective. PMID- 29185090 TI - Meat consumption and pancreatic cancer risk among men and women in the Cancer Prevention Study-II Nutrition Cohort. AB - PURPOSE: Prospective cohort studies suggest that red and processed meat consumption is associated with increased risk of pancreatic cancer among men, but not women. However, evidence is limited, and less evidence exists for other types of meat. METHODS: Cox proportional hazards regression was used to estimate multivariable-adjusted hazard ratios (HR) for the association of meat consumption, by type, with pancreatic cancer risk among 138,266 men and women in the Cancer Prevention Study-II Nutrition Cohort. Diet was assessed at baseline in 1992, and 10 years earlier, at enrollment into the parent CPS-II mortality cohort. 1,156 pancreatic cancers were verified through 2013. RESULTS: Red meat, processed meat, and fish intake at baseline were not associated with pancreatic cancer risk. However, for long-term red and processed meat consumption (highest quartiles in 1982 and 1992, vs. lowest quartiles), risk appeared different in men [hazard ratio (HR) 1.32, 95% confidence interval (CI) 0.90, 1.95] and women (HR 0.72, 95% CI 0.47, 1.10, p heterogeneity by sex = 0.05). Poultry consumption in 1992 was associated with increased pancreatic cancer risk (HR 1.27, 95% CI 1.04, 1.55, p trend = 0.01, top vs. bottom quintile). CONCLUSIONS: The associations of meat consumption with pancreatic cancer risk remain unclear and further research, particularly of long-term intake, is warranted. PMID- 29185091 TI - Induction of apoptosis in breast cancer cells in vitro by Fas ligand reverse signaling. AB - PURPOSE: The Fas-antigen is a cell surface receptor that transduces apoptotic signals into cells. The purpose of this study was to evaluate FasL expression in breast cancer and to elucidate the role of its signaling in different breast cancer cell lines. METHODS: T47D and MCF7 cells were used and cultured in Dulbecco's modified Eagle's medium. FasL translocation to the membrane was achieved by culturing the cells in the presence of human interferon-gamma (IFNgamma). Translocation was detected by immunofluorescence. The ability of a Fas:Fc fusion protein to trigger apoptosis in these cells was investigated by cell death detection ELISA. After incubation with IFNgamma for 4 h and 18 h, apoptosis was assessed in response to treatment with Fas:Fc. RESULTS: Immunofluorescence revealed that the used cell lines were positive for FasL which was increased and changed to more membrane-bound FasL expression after IFNgamma stimulation. After stimulation with 50 IU/ml IFNgamma, Fas:Fc significantly increased MCF7 apoptosis (1.39 +/- 0.06-fold, p = 0.0004) after 18 h. After stimulation with 100 IU/ml, Fas:Fc significantly increased apoptosis both after 4 h (1.49 +/- 0.15-fold, p = 0.018) and 18 h (1.30 +/- 0.06-fold, p = 0.013). In T47D cells this effect was seen after 4 h of stimulation with 50 IU/ml and addition of Fas:Fc (1.6 +/- 0.08-fold, p = 0.03). CONCLUSION: Membrane-bound FasL expression could be induced by IFNgamma in a breast cancer cell model. More importantly, in the presence of IFNgamma the Fas:Fc fusion protein was able to transmit pro-apoptotic signals to T47D and MCF7 cells, significantly inducing apoptosis. The current findings support further in vivo studies regarding FasL activation as a potential target for therapeutic intervention in breast cancer. PMID- 29185093 TI - Sexuality Within Female Same-Gender Couples: Definitions of Sex, Sexual Frequency Norms, and Factors Associated with Sexual Satisfaction. AB - Despite a growing number of female same-gender (FSG) relationships, couples-based research and interventions have focused primarily on mixed-gender couples. Consequently, research has applied a heteronormative lens to understanding some relationship factors, including sexuality. The current study sought to provide descriptive data regarding frequency and conceptualizations of sex across partners in FSG relationships, as well as to analyze how relationship factors are associated with sexual satisfaction in this population. Participants (N = 206) were 103 adult FSG couples who had been together for at least 2 months. Individuals provided self-report data on how they conceptualized sex, and actor partner models were utilized to assess relationship factors associated with sexual satisfaction. Findings indicated that women in FSG relationships hold broad definitions of sex, with the majority of behaviors conceptualized as sex, including acts that involved partnered genital touching. In dyadic actor-partner models, sexual satisfaction was predicted by several factors including sexual frequency, emotional intimacy, and sexual intimacy. Unexpectedly, higher desired sexual frequency was associated with lower sexual satisfaction; however, this finding only emerged after controlling for actual sexual frequency, suggesting that discrepancies between desired and actual sex frequency may be important for FSG couples. Implications for clinical practice with FSG couples are explored, including a strength-based focus on broad conceptualizations of sex within this population and targeting relationship factors associated with sexual satisfaction. PMID- 29185092 TI - Analysis of TSC1 mutation spectrum in mucosal melanoma. AB - PURPOSE: Mucosal melanoma is a relatively rare subtype of melanoma for which no clearly established therapeutic strategy exists. The genes of the mTOR signalling pathway have drawn great attention as key targets for cancer treatment, including melanoma. In this study, we aimed to investigate the mutation status of the upstream mTOR regulator TSC1 and evaluated its correlation with the clinicopathological features of mucosal melanoma. METHODS: We collected 91 mucosal melanoma samples for detecting TSC1 mutations. All the coding exons of TSC1 were amplified by PCR and subjected to Sanger sequencing. Expression level of TSC1 encoding protein (hamartin) was detected by immunohistochemistry. The activation of mTOR pathway was determined by evaluating the phosphorylation status of S6RP and 4E-BP1. RESULTS: The overall mutation frequency of TSC1 was found to be 17.6% (16/91 patients). TSC1 mutations were more inclined to occur in advanced mucosal melanoma (stages III and IV). In the 16 patients with TSC1 mutations, 14 different mutations were detected, affecting 11 different exons. TSC1 mutations were correlated with upregulation of S6RP phosphorylation but were unrelated to 4E-BP1 phosphorylation or hamartin expression. Mucosal melanoma patients with TSC1 mutations had a worse outcome than patients without TSC1 mutations (24.0 versus 34.0 months, P = 0.007). CONCLUSIONS: Our findings suggest that TSC1 mutations are frequent in mucosal melanoma. TSC1 mutations can activate the mTOR pathway through phospho-S6RP and might be a poor prognostic predictor of mucosal melanoma. Our data implicate the potential significance of TSC1 mutations for effective and specific drug therapy for mucosal melanoma. PMID- 29185094 TI - A Theory-Based Exploration of Condomless Anal Intercourse Intention Among Young Men Who Have Sex with Men of Different Sexual Roles in Taiwan. AB - In recent years, men who have sex with men (MSM) have accounted for over 80% of all new HIV cases in Taiwan. More than 70% of new cases have occurred in those aged 15-34 years. Condomless anal intercourse (CAI) has been identified as the main route of HIV transmission among MSM. To systematically examine CAI intention and associated factors among young MSM in Taiwan, an anonymous online survey based on the Theory of Planned Behavior (TPB) was conducted. Data from 694 MSM aged 15-39 years were included in the analysis. This study found that, overall, all five TPB factors (i.e., attitudes toward positive and negative outcomes regarding CAI, perceived support for CAI from important others, and perceived behavioral control of CAI under facilitating and constraining conditions) were significantly associated with CAI intention. When data were stratified by sexual role (i.e., receptive, versatile, and insertive), the associations between TPB factors and CAI intention varied. Of the five TPB factors, positive attitudes toward positive outcomes regarding CAI were most strongly associated with high CAI intention (AOR 5.68 for all young MSM; AOR 3.80-15.93, depending on sexual role). Findings from this study could inform the development of theory-driven HIV prevention programs as well as future research and practice. These results also highlight the importance of tailoring HIV prevention initiatives for young MSM of different sexual roles to optimize the program effectiveness.

AB - Hereditary breast and ovarian cancer (HBOC) syndrome represents 5-10% of all breast cancers. In Japan, the HBOC syndrome is frequently diagnosed in patients with breast cancer. Therefore, a treatment strategy combining a plan for existing breast cancer and for reduction of future breast and ovarian cancer risk is necessary. Breast cancer risk-reducing management involves three options surveillance, chemoprevention, and risk-reducing mastectomy (RRM). RRM can prevent >90% of new breast cancers. Ovarian cancer risk management options are more limited, and risk-reduction salpingo-oophorectomy is the only option since there is no proven effective early detection method available. The local recurrence rate following breast-conserving surgery in BRCA1/2 mutation associated breast cancer is not significantly higher than that in sporadic breast cancer. Furthermore, there is no difference in prognosis between surgical methods. Clinicians should inform patients that there are no data on long-term monitoring and fully discuss risks of re-developing breast cancer with patients when choosing the surgical method. In HBOC, BRCA1/2 mutations lead to failure of double-strand DNA break repair, with poly ADP-ribose polymerase (PARP) playing an important role in single-strand DNA nick repair. Use of PARP inhibitors in HBOC prevents DNA repair (synthetic lethality) leading to cell death. This review summarizes management of the HBOC syndrome based on recent evidence.

PMID- 29185099 TI - Real-life clinical data for dexamethasone and ranibizumab in the treatment of branch or central retinal vein occlusion over a period of six months. AB - PURPOSE: To evaluate the therapeutic outcome for dexamethasone implant (DEX) or intravitreal ranibizumab (IVR) injections over 6 months in patients with macular edema due to branch or central retinal vein occlusion (BRVO, CRVO), in a real life setting. METHODS: A total of 107 patients with BRVO or CRVO were included into this retrospective single-center observational study. Patients were treated with monotherapy consisting of DEX or three monthly IVR injections following a pro re nata regimen (PRN). Best-corrected visual acuity (BCVA), central retinal thickness (CRT) and intraocular pressure (IOP) were compared between the two therapy groups after 1, 3 and 6 months. RESULTS: BRVO patients treated with DEX achieved a statistically significant gain in BCVA measured in logMAR after 1 month (mean gain, 95% CI: 0.21, 0.08-0.34, p = 0.001), 3 months (0.16, 0.03-0.28, p = 0.012) and 6 months (0.19, 0.07-0.32, p = 0.002), whereas patients treated with IVR showed a statistically significant BCVA gain in month 3 (mean improvement, 95% CI: 0.13, 0.01-0.26, p = 0.039) and month 6 (0.16, 0.03-0.29, p = 0.018). BCVA in CRVO patients with DEX worsened slightly at month 6 (mean worsening, 95% CI: -0.08, -0.24 to 0.08, p = 0.305), while IVR treated-patients achieved a statistically significant BCVA gain at 3 months (mean improvement, 95% CI: 0.14, 0.02-0.25, p = 0.021). Both therapies were accompanied by statistically significant CRT reductions of 150 to 200 MUm (median). Adverse events reported were predictable and limited. CONCLUSIONS: In a clinical setting, comparable improvement in BCVA and CRT were observed after DEX and IVR injections for treatment of BRVO. CRVO patients showed greater benefit with IVR. PMID- 29185100 TI - Spatial distribution of CD115+ and CD11b+ cells and their temporal activation during oxygen-induced retinopathy in mice. AB - PURPOSE: The model of oxygen-induced retinopathy (OIR) is widely used to analyze pathomechanisms in retinal neovascularization. Previous studies have shown that macrophages (MP) play a key role in vessel formation in OIR, the influence of microglia (MG) having been discussed. The aim of our study was to analyze the spatial and temporal distribution and activation of MP/MG expressing CD115 and CD11b during the process of neovascularization in OIR. METHODS: We used MacGreen mice expressing the green fluorescence protein (GFP) under the promoter for CD115. CD115+ cells were investigated in vivo by scanning laser ophthalmoscopy at postnatal days (P) 17 and 21 in MacGreen mice with OIR (75% oxygen from P7 to P12), and were compared to MacGreen room-air controls. In addition MP/MG were examined ex vivo using immunohistochemistry for CD11b+ detection on retinal flatmounts at P14, P17, and P21 of wild type mice with OIR. RESULTS: In-vivo imaging revealed the highest density of activated MP/MG in tuft areas at P17 of MacGreen mice with OIR. Tufts and regions with a high density of CD115+ cells were detected close to veins, rather to arteries. In peripheral, fully vascularized areas, the distribution of CD115+ cells in MacGreen mice with OIR was similar to MacGreen room-air controls. Correspondingly, immunohistochemical analyses of retinal flatmounts from wild type mice with OIR induction revealed that the number of CD11b+ cells significantly varies between vascular, avascular, and tuft areas as well as between the retinal layers. Activated CD11b+ cells were almost exclusively found in avascular areas and tufts of wild type mice with OIR induction; here, the proportion of activated cells related to the total number of CD11b+ cells remained stable over the course of time. CONCLUSIONS: Using two different approaches to monitor MP/MG cells, our findings demonstrated that MP/MG concentrate within pathologically vascularized areas during OIR. We were able to clarify that reactive changes of CD11b+ cell distribution to OIR primarily occur in the deep retinal layers. Furthermore, we found the highest proportion of activated CD11b+ cells in regions with pathologic neovascularization processes. Our findings support previous reports about activated MP/MG guiding revascularization in avascular areas and playing a key role in the formation and regression of neovascular tufts. PMID- 29185102 TI - Systematic Layout Planning of a Radiology Reporting Area to Optimize Radiologists' Performance. AB - Optimizing radiologists' performance is a major priority for managers of health services/systems, since the radiologists' reporting activity imposes a severe constraint on radiology productivity. Despite that, methods to optimize radiologists' reporting workplace layout are scarce in the literature. This study was performed in the Radiology Division (RD) of an 850-bed University-based general hospital. The analysis of the reporting workplace layout was carried out using the systematic layout planning (SLP) method, in association with cluster analysis as a complementary tool in early stages of SLP. Radiologists, architects, and hospital managers were the stakeholders consulted for the completion of different stages of the layout planning process. A step-by-step description of the proposed methodology to plan an RD reporting layout is presented. Clusters of radiologists were defined using types of exams reported and their frequency of occurrence as clustering variables. Sectors with high degree of interaction were placed in proximity in the new RD layout, with separation of noisy and quiet areas. Four reporting cells were positioned in the quiet area, grouping radiologists by subspecialty, as follows: cluster 1-abdomen; cluster 2-musculoskeletal; cluster 3-neurological, vascular and head & neck; cluster 4-thoracic and cardiac. The creation of reporting cells has the potential to limit unplanned interruptions and enhance the exchange of knowledge and information within cells, joining radiologists with the same expertise. That should lead to improvements in productivity, allowing managers to more easily monitor radiologists' performance. PMID- 29185103 TI - Unraveling the Interaction of Aspirin, Ticagrelor, and Rosuvastatin on the Progression of Atherosclerosis and Inflammation in Diabetic Mice. AB - PURPOSE: We explored the effects of rosuvastatin, aspirin, ticagrelor, and clopidogrel, alone or in combinations on the progression of atherosclerosis and inflammasome activation in diabetic mice. Statins and ticagrelor increase the production of 15-epi-lipoxin A4 via cyclooxygenase-2. Aspirin alone increases 15 epi-lipoxin A4, but when combined with statins, cyclooxygenase-2 is completely blocked. METHODS: ApoE-/-/db+/db+ double-knockout mice received rosuvastatin (5 mg/kg/day), aspirin (25 mg/kg/day), ticagrelor (300 mg/kg/day), clopidogrel (75 mg/kg/day), or their combination for 14 weeks. Serum 15-epi-lipoxin A4 levels and aortic wall cholesterol content, IL-1beta, IL-6, and TNF-alpha levels, and plaque area were assessed. RESULTS: Aspirin, ticagrelor, and rosuvastatin increased 15 epi-lipoxin A4 levels. The combination of rosuvastatin + ticagrelor provided an additive effect. Aspirin attenuated the effect of both ticagrelor and rosuvastatin. Aspirin, ticagrelor, and rosuvastatin reduced the area of the atherosclerotic plaque. The combination of ticagrelor + rosuvastatin provided additive effects. There was a negative interaction when aspirin was combined with ticagrelor or rosuvastatin. Aspirin, ticagrelor, and rosuvastatin decreased serum IL-1beta and IL-6 levels. There was no interaction between aspirin and ticagrelor or aspirin and rosuvastatin, whereas combining rosuvastatin and ticagrelor provided an additive effect. Aspirin, ticagrelor, and rosuvastatin all decreased TNF-alpha levels. Aspirin attenuated the effect of both ticagrelor and rosuvastatin, and there was no additive effect of combining ticagrelor + rosuvastatin. CONCLUSIONS: We found an intricate interaction between aspirin, ticagrelor, and rosuvastatin, as aspirin reduced both ticagrelor and rosuvastatin ability to ameliorate inflammation and atherosclerosis. In contrast, we found additive effects when ticagrelor and rosuvastatin were combined. PMID- 29185101 TI - Association between traditional clinical high-risk features and gene expression profile classification in uveal melanoma. AB - PURPOSE: To evaluate the association between traditional clinical high-risk features of uveal melanoma patients and gene expression profile (GEP). METHODS: This was a retrospective, single-center, case series of patients with uveal melanoma. Eighty-three patients met inclusion criteria for the study. Patients were examined for the following clinical risk factors: drusen/retinal pigment epithelium (RPE) changes, vascularity on B-scan, internal reflectivity on A-scan, subretinal fluid (SRF), orange pigment, apical tumor height/thickness, and largest basal dimensions (LBD). A novel point system was created to grade the high-risk clinical features of each tumor. Further analyses were performed to assess the degree of association between GEP and each individual risk factor, total clinical risk score, vascularity, internal reflectivity, American Joint Committee on Cancer (AJCC) tumor stage classification, apical tumor height/thickness, and LBD. RESULTS: Of the 83 total patients, 41 were classified as GEP class 1A, 17 as class 1B, and 25 as class 2. The presence of orange pigment, SRF, low internal reflectivity and vascularity on ultrasound, and apical tumor height/thickness >= 2 mm were not statistically significantly associated with GEP class. Lack of drusen/RPE changes demonstrated a trend toward statistical association with GEP class 2 compared to class 1A/1B. LBD and advancing AJCC stage was statistically associated with higher GEP class. CONCLUSIONS: In this cohort, AJCC stage classification and LBD were the only clinical features statistically associated with GEP class. Clinicians should use caution when inferring the growth potential of melanocytic lesions solely from traditional funduscopic and ultrasonographic risk factors without GEP data. PMID- 29185104 TI - 5alpha-Reductase isozymes and aromatase mRNA levels in plucked hair from young women with female pattern hair loss. AB - Female pattern hair loss (FPHL) is an important hair disorder, especially when young women are affected. However, pharmacological treatments are not successful in all women. Androgens, especially dihydrotestosterone (DHT), may play a role in FPHL, but many women with this disorder have normal serum androgen levels. It therefore appears that hair follicle levels of DHT depend on in situ testosterone (T) metabolism. Because T can be converted to DHT or estradiol (E2) by 5alpha reductase (5alpha-R) and aromatase, respectively, these enzymes would determine DHT and E2 concentrations and their ratio. We propose and apply a low-invasive, sensitive and precise method for the absolute quantification of mRNA levels of aromatase and 5alpha-R isozymes (type 1, type 2 and type 3) in plucked hair from young women with FPHL. Normoandrogenic women with FPHL and controls were studied. Plucked hair samples were obtained by trichogram from vertex scalp and mRNA levels quantified by real-time RT-PCR. We revealed for the first time the presence of 5alpha-R3 mRNA in human hair. Interestingly, one, two, or even three 5alpha-R isozymes were increased in some women with FPHL but not in others, which may explain the lack of response to 5alpha-R inhibitors in some FPHL cases. Aromatase mRNA levels were significantly lower in women with FPHL than in controls. It may therefore produce a reduction in oestrogen levels and an increase in the androgen/oestrogen ratio in hair. The proposed low-invasive technique offers a molecular aetiologic diagnosis of FPHL for the selection of more appropriate pharmacological treatments with early predicted effectiveness. PMID- 29185106 TI - Efficacy of carvedilol versus propranolol versus variceal band ligation for primary prevention of variceal bleeding. AB - BACKGROUND AND AIMS: Band ligation and propranolol are the current therapies for primary prevention of variceal bleeding. Carvedilol is a rising nonselective beta blocker used for reducing portal pressure with favorable outcome. The aim of this study to assess the efficacy of carvedilol, propranolol, and band ligation for primary prevention of variceal bleeding based on the effect of each regimen on progression of Child score and portal hypertensive gastropathy after 1 year. METHODS: The study included 264 cirrhotic patients with medium/large-sized varices who were candidates for primary prophylaxis of variceal bleeding. Patients were randomly divided into three groups: group I: band ligation; group II: propranolol; group III: carvedilol. RESULTS: Group I showed higher success rate of 75 %, followed by group III with 70.2 % and group II with 65.2 %. Risk of bleeding was comparable between the three groups, with group II carrying the highest rate of complications (34.7 %) followed by group III (14.2 %) and finally group I (5.7 %). After 1 year of follow-up, Child score did not improve in any of the studied groups, while portal hypertensive gastropathy significantly increased in group I but decreased in groups II and III. CONCLUSIONS: Band ligation is the best treatment option for primary prevention of variceal bleeding with minimal complications. Carvedilol is a good pharmaceutical alternative medicine to propranolol with lesser side-effects. Progress of liver disease as represented by Child score is not affected by any of the primary variceal prophylactic regimens, although medical treatment reduces portal hypertensive gastropathy. Choice of treatment depends on patient will, compliance with treatment, and endoscopist competence. PMID- 29185105 TI - Barriers and facilitators of exercise experienced by cancer survivors: a mixed methods systematic review. AB - PURPOSE: Exercise has been shown to improve the health and well-being of people who have survived cancer. Yet, less than 40% of cancer survivors in Australia meet the recommended 150 min of moderate-intensity physical activity per week. Our objective was to systematically review the literature regarding barriers, facilitators and preferences for exercise for survivors of cancer. METHOD: MEDLINE, EMBASE, CINAHL, PsycINFO and Scopus were searched for qualitative and quantitative articles addressing barriers, facilitators and preferences for exercise in cancer survivors. Quality assessment was performed by two independent reviewers using the Mixed Methods Appraisal Tool. Thomas and Harden's method of thematic synthesis was used to amalgamate qualitative data while descriptive statistics were used to collate quantitative data. RESULTS: Nineteen studies were included (9 qualitative and 10 quantitative). Persisting treatment-related side effects was the most commonly reported barrier to initiating or maintaining exercise, followed by lack of time and fatigue. The most common facilitators of exercise were gaining a feeling of control over their health as well as managing emotions and mental well-being, while the preferred method of exercise was walking. We also identified a lack of useful information provided to survivors regarding exercise. CONCLUSION: Treatment-related side effects, lack of time and fatigue were key barriers to exercise for survivors of varied cancer types. Insufficient patient education may contribute to the belief that exercise is not helpful when experiencing side effects of treatment, including fatigue. Identifying barriers and facilitators leads to improved support and education from health professionals which is required to provide safe and effective exercise recommendations for survivors. PMID- 29185107 TI - Organization of auditory areas in the superior temporal gyrus of marmoset monkeys revealed by real-time optical imaging. AB - The prevailing model of the primate auditory cortex proposes a core-belt-parabelt structure. The model proposes three auditory areas in the lateral belt region; however, it may contain more, as this region has been mapped only at a limited spatial resolution. To explore this possibility, we examined the auditory areas in the lateral belt region of the marmoset using a high-resolution optical imaging technique. Based on responses to pure tones, we identified multiple areas in the superior temporal gyrus. The three areas in the core region, the primary area (A1), the rostral area (R), and the rostrotemporal area, were readily identified from their frequency gradients and positions immediately ventral to the lateral sulcus. Three belt areas were identified with frequency gradients and relative positions to A1 and R that were in agreement with previous studies: the caudolateral area, the middle lateral area, and the anterolateral area (AL). Situated between R and AL, however, we identified two additional areas. The first was located caudoventral to R with a frequency gradient in the ventrocaudal direction, which we named the medial anterolateral (MAL) area. The second was a small area with no obvious tonotopy (NT), positioned between the MAL and AL areas. Both the MAL and NT areas responded to a wide range of frequencies (at least 2-24 kHz). Our results suggest that the belt region caudoventral to R is more complex than previously proposed, and we thus call for a refinement of the current primate auditory cortex model. PMID- 29185108 TI - Neuronal density and proportion of interneurons in the associative, sensorimotor and limbic human striatum. AB - The striatum (caudate nucleus, putamen and nucleus accumbens) is the main input structure of the basal ganglia. It receives cortical projections from the vast majority of the cortex, as well as from other subcortical structures such as the thalamus and amygdala. Its role in planning, preparation and execution of voluntary movements is known to be fine-tuned by the interaction between projection neurons and interneurons. Since the 1990s, it has been accepted that the proportion of interneurons increases phylogenetically, being about 5% in rodents and 26% in humans. However, these data have not been confirmed with unbiased techniques, such as stereology. In the present report, we have divided the human striatum into functional territories (associative, sensorimotor and limbic) and we have quantified the numerical density of all striatal neurons (using Nissl staining) in each area. Taking into account our past research on the estimation of striatal interneurons, we have calculated the proportion of interneurons in each territory. This value was on average 17.1% for the whole striatum, although interneurons were more abundant in the associative (21.9%) than in the sensorimotor (12.8%) and limbic (11.1%) aspects. Therefore, we demonstrate with unbiased stereology that the overall proportion of striatal interneurons is slightly lower than that reported in previous studies, and that it varies in the functional territories of this structure. PMID- 29185109 TI - Higher similarity in beta topography between tasks than subjects. AB - We have recently provided evidence for highly idiosyncratic topographic distributions of beta oscillations (as well as slow potentials) across individuals. More recently, by emphasizing the analysis of similarity instead of differences across tasks, we concluded that differences between an attention task and quiet resting may be negligible or at least unsystematic across subjects. Due to the possibility that individual differences could be due to noise in a wide sense or some inherent instability of beta activity, we designed a replication study to explicitly test whether pairs of individuals matched for head size and shape would still present less similar beta topography than each individual between sessions or tasks. We used independent component analysis (ICA) for an exhaustive decomposition of beta activity in a visual attention task and in quiet resting, recorded by 256-channel EEG in 20 subjects, on two separate days. We evaluated whether each ICA component obtained in one task and in one given individual could be explained by a linear regression model based on the topographic patterns of the complementary task (correlation between one component with a linear combination of components from complementary conditions), of the same task in a second session and of a matched individual. Results again showed a high topographic similarity between conditions, as previously seen between reasoning and simple visual attention beta correlates. From an overall number of 16 components representing brain activity obtained for the tasks (out of 60 originally computed where the remaining were considered noise), over 92% could satisfactorily be explained by the complementary task. Although the similarity between sessions was significantly smaller than between tasks on each day, the similarity between sessions was statistically higher than that between subjects in a highly significant way. We discuss the possible biases of group spatial averaging and the emphasis on differences as opposed to similarities, and noise in a wide sense, as the main causes of hardly replicable findings on task-related forms of activity and the inconclusive state of a universal functional mapping of cortical association areas. PMID- 29185110 TI - Concurrent validity of photogrammetric and inclinometric techniques based on assessment of anteroposterior spinal curvatures. AB - PURPOSE: The purpose of the study was to investigate correlations between parameters of anteroposterior spinal curvatures in the sagittal plane, measured with the use of photogrammetric technique and inclinometer in healthy elderly women. METHODS: Randomized study involved 50 females, ranging from 50 to 70 years of age (mean 62.26 +/- 6.94); mean body mass index (BMI) 27.69 +/- 4.79. The examined parameters included angle of inclination in lumbosacral spine (ALFA), thoracolumbar transition (BETA), upper thoracic segment (GAMMA), angle of lumbar lordosis (LLA) and thoracic kyphosis (TKA). Results obtained with gravitational inclinometer were compared with those identified with photogrammetry method. Statistical analyses were performed with Mann-Whitney U test, regression analysis and Bland-Altman analysis. RESULTS: In Mann-Whitney U test, with correction due to continuity, no statistically significant differences for any variable were found. Regression analysis was significant only for the variable of BETA angle. Bland-Altman coefficient for the respective angles was: ALFA 2.0%, BETA 4%, GAMMA 0%, LLA 2% and TKA 0%. CONCLUSIONS: The results acquired with gravitational inclinometer and with photogrammetric technique are comparable, as the parameters of anteroposterior spinal curvatures acquired with these two methods are found to be compatible in the case of measurements of lumbar lordosis and thoracic kyphosis. PMID- 29185111 TI - Factors influencing spinal sagittal balance, bone mineral density, and Oswestry Disability Index outcome measures in patients with rheumatoid arthritis. AB - PURPOSE: To identify the factors influencing spinal sagittal alignment, bone mineral density (BMD), and Oswestry Disability Index (ODI) outcome measures in patients with rheumatoid arthritis (RA). METHODS: We enrolled 272 RA patients to identify the factors influencing sagittal vertical axis (SVA). Out of this, 220 had evaluation of bone mineral density (BMD) and vertebral deformity (VD) on the sagittal plane; 183 completed the ODI questionnaire. We collected data regarding RA-associated clinical parameters and standing lateral X-ray images via an ODI questionnaire from April to December 2012 at a single center. Patients with a history of spinal surgery or any missing clinical data were excluded. Clinical parameters included age, sex, body mass index, RA disease duration, disease activity score 28 erythrocyte sedimentation rate (DAS28-ESR), serum anti-cyclic citrullinated peptide antibody, serum rheumatoid factor, serum matrix metalloproteinase-3, BMD and treatment type at survey, such as methotrexate (MTX), biological disease-modifying anti-rheumatic drugs, and glucocorticoids. We measured radiological parameters including pelvic incidence (PI), lumbar lordosis (LL), and SVA. We statistically identified the factors influencing SVA, BMD, VD, and ODI using multivariate regression analysis. RESULTS: Multivariate regression analysis showed that larger SVA correlated with older age, higher DAS28-ESR, MTX nonuse, and glucocorticoid use. Lower BMD was associated with female, older age, higher DAS28-ESR, and MTX nonuse. VD was associated with older age, longer disease duration, lower BMD, and glucocorticoid use. Worse ODI correlated with older age, larger PI-LL mismatch or larger SVA, higher DAS28-ESR, and glucocorticoid use. CONCLUSIONS: In managing low back pain and spinal sagittal alignment in RA patients, RA-related clinical factors and the treatment type should be taken into consideration. PMID- 29185112 TI - Prospective multi-centric evaluation of upper cervical and infra-cervical sagittal compensatory alignment in patients with adult cervical deformity. AB - PURPOSE: Reciprocal mechanisms for standing alignment have been described in thoraco-lumbar deformity but have not been studied in patients with primary cervical deformity (CD). The purpose of this study is to report upper- and infra cervical sagittal compensatory mechanisms in patients with CD and evaluate their changes post-operatively. METHODS: Global spinal alignment was studied in a prospective database of operative CD patients. Inclusion criteria were any of the following: cervical kyphosis (CK) > 10 degrees , cervical scoliosis > 10 degrees , cSVA (C2-C7 Sagittal vertical axis) > 4 cm or CBVA (Chin Brow Vertical Angle) > 25 degrees . For this study, patients who had previous fusion outside C2 to T4 segments were excluded. Patients were sub-classified by increasing severity of cervical kyphosis [CL (cervical lordosis): < 0 degrees , CK-low 0 degrees -10 degrees , CK-high > 10 degrees ] and cSVA (cSVA-low 0-4 cm, cSVA-mid 4-6 cm, cSVA high > 6 cm) and were compared for pre- and 3-month post-operative regional and global sagittal alignment to determine compensatory recruitment. RESULTS: 75 CD patients (mean age 61.3 years, 56% women) were included. Patients with progressively larger CK had a progressive increase in C0-C2 (CL = 34 degrees , CK low = 37 degrees , CK-high = 44 degrees , p = 0.004), C2Slope and T1Slope-CL (p < 0.05). As the cSVA increased, there was progressive increase in C2Slope, T1Slope and TS-CL (p < 0.05) and patients compensated through increasing C0-C2 (cSVA-low = 33 degrees , cSVA-mid = 40 degrees , cSVA-high = 43 degrees , p = 0.007) and pelvic tilt (cSVA-low = 14.9 degrees , cSVA-mid = 24.1 degrees , cSVA-high = 24.9 degrees , p = 0.02). At 3 months post-op, with significant improvement in cervical alignment, there was relaxation of C0-C2 (39 degrees -35 degrees , p = 0.01) which positively correlated with magnitude of deformity correction. CONCLUSIONS: Patients with cervical malalignment compensate with upper cervical hyper-lordosis, presumably for the maintenance of horizontal gaze. As cSVA increases, patients also tend to exhibit increased pelvic retroversion. Following surgical treatment, there was relaxation of upper cervical compensation. PMID- 29185113 TI - Cross Validation of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI/GPSS) on a Sample of Ontario High School Students. AB - This paper reports on the cross validation of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI/GPSS). The CAGI/GPSS was included in a large school based drug use and health survey conducted in 2015. Data from students in grades 9-12 (ages 13-20 years) derived from the (N = 3369 students). The CAGI/GPSS produced an alpha of 0.789. A principle component analysis revealed two eigenvalues greater than one. An oblique rotation revealed these components to represent consequences and over involvement. The CAGI/GPSS indicated that 1% of the students fell into the "red" category indicating a severe problem and an additional 3.3% scored in the "yellow" category indicating low to moderate problems. The CAGI/GPSS was shown to be significantly correlated with gambling frequency (r = 0.36), largest expenditure (r = 0.37), sex (more likely to be male) (r = -0.19), lower school marks (r = -0.07), hazardous drinking, (r = 0.16), problem video game play (r = 0.16), as well as substance abuse. The CAGI/GPSS was cross validated using a shorted version of the short SOGS, r = 0.48. In addition the CAGI/GPSS and short SOGS produced very similar patterns of correlations results. The results support the validity and reliability of the CAGI/GPSS as a measure of gambling problems among adolescents. PMID- 29185114 TI - Growth morphology of CL-20/HMX cocrystal explosive: insights from solvent behavior under different temperatures. AB - A 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20) /1,3,5,7 tetranitro-1,3,5,7-tetrazacyclooctane (HMX)-isopropanol (IPA) interfacial model was constructed to investigate the effect of temperature on cocrystal morphology. A constant volume and temperature molecular dynamics (NVT-MD) simulation was performed on the interfacial model at various temperatures (295-355 K, 20 K intervals). The surface electrostatic potential (ESP) of the CL-20/HMX cocrystal structure and IPA molecule were studied by the B3LYP method at 6-311++G (d, p) level. The surface energies, polarities, adsorption energy, mass density distribution, radial distribution function (RDF), mean square displacement (MSD) and relative changes of attachment energy were analyzed. The results show that polarities of (1 0 0) and (0 1 1) cocrystal surfaces may be more negative and affected by IPA solvent. The adsorption energy per area indicates that growth of the (1 0-2) face in IPA conditions may be more limited, while the (1 0 0) face tends to grow more freely. MSD and diffusion coefficient (D) analyses demonstrated that IPA molecules gather more easily on the cocrystal surface at lower temperatures, and hence have a larger effect on the growth of cocrystal faces. RDF analysis shows that, with the increasing of temperature, the strength of hydrogen bond interactions between cocrystal and solvent becomes stronger, being highest at 335 K for the (1 0 0) and (0 1 1) interfacial models. Results of relative changes of modified attachment energy show that (1 0 0) and (0 1 1) faces tends to be larger than other faces. Moreover, the predicted morphologies at 295 and 355 K are consistent with experimental values, proving that the CL 20/HMX-IPA interfacial model is a reasonable one for this study. Graphical Abstract Construction of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12 hexaazaisowurtzitane (CL-20) /1,3,5,7-tetranitro-1,3,5,7-tetrazacyclooctane (HMX) isopropanol (IPA) interfacial model, analysis, and morphology prediction of cocrystal. PMID- 29185115 TI - The synergistic effect of nsP2-L618, nsP3-R117, and E2-K187 on the large plaque phenotype of chikungunya virus. AB - Chikungunya virus (CHIKV), a mosquito-borne Alphavirus, is the etiological agent of chikungunya fever. CHIKV re-emerged from 2004 onwards, and subsequently caused major outbreaks in many parts of the world including the Indian Ocean islands, Asia, and the Americas. In this study, a large plaque variant of CHIKV isolated from patient in Thailand was subjected to repeated cycles of plaque-purification in Vero cells. The resulting virus produced homogenous large plaques and showed a more pathogenic phenotype than the parental wild-type CHIKV. Whole genome analysis of the large plaque virus in comparison to parental isolate revealed a number of mutations, leading to the following amino acid changes: nsP2 (P618->L), nsP3 (G117->R), and E2 (N187->K). Eight recombinant CHIKVs were constructed to determine which amino acids mediated the large plaque phenotype. The results showed the recombinant virus which contains all three mutations, rCHK-L, produced significantly larger plaques than the other recombinant viruses (p < 0.01). Moreover, the plaque size of the other recombinant virus tended to be smaller if they contained only one or two of the large plaque associated mutations in the viral genome. In conclusion, the combination of all three residues (nsP2-L618, nsP3-R117, and E2-K187) is required to produce the large plaque phenotype of CHIKV. PMID- 29185116 TI - Standard, transepithelial and iontophoresis corneal cross-linking: clinical analysis of three surgical techniques. AB - BACKGROUND: To evaluate the clinical results of standard, transepithelial (TE) and iontophoresis (I) corneal cross-linking (CXL), in patients with progressive keratoconus. METHODS: Thirty eyes of 30 patients with progressive keratoconus treated by CXL (10 by standard-CXL, 10 by TE-CXL and 10 by I-TE-CXL) with 12 months of follow-up. Pre- and postoperative ophthalmologic testing were: uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refractive examination (spherical error, spherical equivalent), corneal topography (corneal astigmatism, simulated maximum, minimum and average keratometry), aberrometry (coma and spherical aberration), pachymetry and endothelial cell density. RESULTS: In all groups, UDVA and CDVA improved significantly after treatment. Furthermore, a significant improvement in spherical error, spherical equivalent, topographic and aberrometric outcomes was observed in 3 groups at 1 year posttreatment. No significant variations were recorded in corneal thickness and endothelial cellular density. CONCLUSION: Our results showed efficacy, clinical and refractive stability after standard-CXL, TE CXL and iontophoresis-CXL. PMID- 29185117 TI - Algoriphagus formosus sp. nov., isolated from coastal sediment. AB - A Gram-stain negative, facultative anaerobic, non-motile, strongly orange pigmented and rod-shaped bacterium, designated XAY3209T, was isolated from a marine sediment sample collected from the coast of Weihai, China. Strain XAY3209T was found to grow optimally at 30 degrees C, at pH 7.0 and in the presence of 2.0% (w/v) NaCl. Its genomic DNA G+C content was 41.9 mol%. On the basis of 16S rRNA gene sequence similarity, the novel isolate belongs to the family Cyclobacteriaceae and is related to the genus Algoriphagus. It shares 98.1% 16S rRNA sequence identity with Algoriphagus marincola, its close phylogenetic relative, but did not show similarities more than 97% with other members of the genus Algoriphagus with validly published names. It contained menaquinone-7 (MK 7) as the sole respiratory quinone, iso-C15:0, iso-C17:1 omega9c and Summed feature 3 (C16:1 omega7c and/or iso-C15:0 2-OH) as the major fatty acids. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid, one unidentified phospholipid and five unidentified lipids. Results of physiological experiments, biochemical tests and genome average nucleotide identity value (with A. marincola MCCC 1F01203T) indicate that strain XAY3209T is genetically and phenotypically distinct from the species of the genus Algoriphagus with validly published names. Strain XAY3209T therefore represents a novel species, for which the name Algoriphagus formosus sp. nov. is proposed. The type strain is XAY3209T (= KCTC 52842T = MCCC 1H00189T). PMID- 29185119 TI - PRMT5 determines the sensitivity to chemotherapeutics by governing stemness in breast cancer. AB - PURPOSE: Acquired resistance to chemotherapeutic agents in breast cancer is a major clinical challenge. Recent studies have shown that the emergence of cancer stem cells contributes to the development of drug resistance, and the protein arginine methyltransferase 5 (PRMT5) was crucial for the maintenance of stemness. However, the roles of PRMT5 in breast cancer cell stemness and the development of cancer drug resistance have not been clarified. In this study, we investigated the effect of PRMT5 on the sensitivity to doxorubicin and cell stemness in breast cancer. METHODS: PRMT5 expression was assessed in a panel of breast cancer cell lines (MDA-MB-231, MCF7, T-47D, BT-474, Au-565) and normal mammal epithelial cells (MCF10A). For knockdown of PRMT5 expression, two pairs of shRNAs as well as a control shRNA were utilized. Meanwhile, the wild-type PRMT5 and its catalytically dead counterpart (R368A) were stably overexpressed in MDA-MB-231 and MCF7 cells. The sensitivity to doxorubicin was determined by MTT assays, TUNEL assays, and Western blot analyses. To evaluate the degree of cell stemness, CD24/CD44-sorting and mammosphere formation experiments were performed. RESULTS: We demonstrated that PRMT5 regulates OCT4/A, KLF4, and C-MYC in breast cancer to govern stemness and affects the doxorubicin resistance of breast cancer. CONCLUSION: Our study suggests that PRMT5 may play an important role in the doxorubicin resistance of breast cancer. PMID- 29185118 TI - Comparative effectiveness of incorporating a hypothetical DCIS prognostic marker into breast cancer screening. AB - PURPOSE: Due to limitations in the ability to identify non-progressive disease, ductal carcinoma in situ (DCIS) is usually managed similarly to localized invasive breast cancer. We used simulation modeling to evaluate the potential impact of a hypothetical test that identifies non-progressive DCIS. METHODS: A discrete-event model simulated a cohort of U.S. women undergoing digital screening mammography. All women diagnosed with DCIS underwent the hypothetical DCIS prognostic test. Women with test results indicating progressive DCIS received standard breast cancer treatment and a decrement to quality of life corresponding to the treatment. If the DCIS test indicated non-progressive DCIS, no treatment was received and women continued routine annual surveillance mammography. A range of test performance characteristics and prevalence of non progressive disease were simulated. Analysis compared discounted quality-adjusted life years (QALYs) and costs for test scenarios to base-case scenarios without the test. RESULTS: Compared to the base case, a perfect prognostic test resulted in a 40% decrease in treatment costs, from $13,321 to $8005 USD per DCIS case. A perfect test produced 0.04 additional QALYs (16 days) for women diagnosed with DCIS, added to the base case of 5.88 QALYs per DCIS case. The results were sensitive to the performance characteristics of the prognostic test, the proportion of DCIS cases that were non-progressive in the model, and the frequency of mammography screening in the population. CONCLUSION: A prognostic test that identifies non-progressive DCIS would substantially reduce treatment costs but result in only modest improvements in quality of life when averaged over all DCIS cases.

AB - PURPOSE: Germline mutations in BRCA1 and BRCA2 confer a significant increase in risk for cancer, and determining pathogenicity of a BRCA variant can guide the clinical management of the disease. About 1/3 of BRCA1 variants reported in the public databases have uncertain clinical significance due to lack of conclusive evidence. This study aims to characterize a novel BRCA1 deletion affecting the + 4 splice donor site identified in an individual with early-onset breast cancer. METHODS: The effect of BRCA1 c.5332+4delA variant on RNA splicing was evaluated by amplifying regions of BRCA1 from cDNA derived from the patient. The proportion of abnormal transcript in the total transcripts was quantified. Loss of heterozygosity (LOH) in tumor tissue was investigated using Sanger sequencing and fragment analysis. RESULTS: BRCA1 c.5332+4delA caused skipping of exon 21 in patient-derived samples. Semi-quantitative analysis indicated that this aberrant RT-PCR product accounts for about 40% of the total transcript levels. Loss of heterozygosity (LOH) was observed in patient's tumor tissue. CONCLUSIONS: Our results indicate that the BRCA1 c.5332+4delA variant contributes to cancer predisposition through disruption of normal mRNA splicing. We classify this variant as likely pathogenic.

AB - Spin-polarized first-principles total-energy calculations have been performed to investigate the possible chain reaction of acetylene molecules mediated by hydrogen abstraction on hydrogenated hexagonal boron nitride monolayers. Calculations have been done within the periodic density functional theory (DFT), employing the PBE exchange correlation potential, with van der Waals corrections (vdW-DF). Reactions at two different sites have been considered: hydrogen vacancies on top of boron and on top of nitrogen atoms. As previously calculated, at the intermediate state of the reaction, when the acetylene molecule is attached to the surface, the adsorption energy is of the order of -0.82 eV and 0.20 eV (measured with respect to the energy of the non interacting molecule substrate system) for adsorption on top of boron and nitrogen atoms, respectively. After the hydrogen abstraction takes place, the system gains additional energy, resulting in adsorption energies of -1.52 eV and -1.30 eV, respectively. These results suggest that the chain reaction is energetically favorable. The calculated minimum energy path (MEP) for hydrogen abstraction shows very small energy barriers of the order of 5 meV and 22 meV for the reaction on top of boron and nitrogen atoms, respectively. Finally, the density of states (DOS) evolution study helps to understand the chain reaction mechanism. Graphical abstract Acetylene chain reaction on hydrogenated boron nitride monolayers.

AB - Lung squamous cell carcinoma (LUSC) causes approximately 400 000 deaths each year worldwide. The occurrence of LUSC is attributed to exposure to cigarette smoke, which induces the development of numerous genomic abnormalities. However, few studies have investigated the genomic variations that occur only in normal tissues that have been similarly exposed to tobacco smoke as tumor tissues. In this study, we sequenced the whole genomes of three normal lung tissue samples and their paired adjacent squamous cell carcinomas.We then called genomic variations specific to the normal lung tissues through filtering the genomic sequence of the normal lung tissues against that of the paired tumors, the reference human genome, the dbSNP138 common germline variants, and the variations derived from sequencing artifacts. To expand these observations, the whole exome sequences of 478 counterpart normal controls (CNCs) and paired LUSCs of The Cancer Genome Atlas (TCGA) dataset were analyzed. Sixteen genomic variations were called in the three normal lung tissues. These variations were confirmed by Sanger capillary sequencing. A mean of 0.5661 exonic variations/Mb and 7.7887 altered genes per sample were identified in the CNC genome sequences of TCGA. In these CNCs, C:G->T:A transitions, which are the genomic signatures of tobacco carcinogen N-methyl-N-nitro-N-nitrosoguanidine, were the predominant nucleotide changes. Twenty five genes in CNCs had a variation rate that exceeded 2%, including ARSD (18.62%), MUC4 (8.79%), and RBMX (7.11%). CNC variations in CTAGE5 and USP17L7 were associated with the poor prognosis of patients with LUSC. Our results uncovered previously unreported genomic variations in CNCs, rather than LUSCs, that may be involved in the development of LUSC. PMID- 29185123 TI - Is Timing of Enrollment Associated with Birth Outcomes? Findings from a Healthy Start Program in Kansas. AB - Objective The Sedgwick County Healthy Babies Healthy Start (HBHS) program provides community-based services (including care coordination, interconception care and home visiting) aimed at reducing racial/ethnic disparities in poor birth outcomes. The purpose of this study is to assess the effectiveness of the Sedgwick County HBHS program by comparing the birth outcomes of program participants who enrolled prenatally and those who did not participate while pregnant. Methods In this retrospective cohort study, we used data drawn from the Sedgwick County HBHS program. The sample included 280 clients who were enrolled in the Sedgwick County HBHS program between September 2014 and December 2015. We performed logistic regression analyses to assess the associations between enrollee type (prenatal enrollee vs. interconceptional enrollee) and birth outcomes (low birth weight, preterm birth). Results The majority of the sample consisted of racial/ethnic minority women (32.1% non-Hispanic black, 31.8% Hispanic). After adjusting for covariates, women who enrolled in the Sedgwick County HBHS program prenatally were less likely than women who were not enrolled during pregnancy to have a preterm birth (OR 0.19, [CI 08, 0.43]) and deliver a low birth weight infant (OR 0.31, [CI 0.10, 0.97]). Conclusions for Practice Women, particularly minority women, who participate in the HBHS program experienced better birth outcomes than women who did not participate in the program during pregnancy. However, findings also suggest that interconceptional enrollees may stand to benefit from continued participation in the program. PMID- 29185124 TI - The role of DNA sequence in nucleosome breathing. AB - Roughly 3/4 of human genomes are sequestered by nucleosomes, DNA spools with a protein core, dictating a broad range of biological processes, ranging from gene regulation, recombination, and replication, to chromosome condensation. Nucleosomes are dynamical structures and temporarily expose wrapped DNA through spontaneous unspooling from either end, a process called site exposure or nucleosome breathing. Here we ask how this process is influenced by the mechanical properties of the wrapped DNA, which is known to depend on the underlying base pair sequence. Using a coarse-grained nucleosome model we calculate the accessibility profiles for site exposure. We find that the process is very sensitive to sequence effects, so that evolution could potentially tune the accessibility of nucleosomal DNA and would only need a small number of mutations to do so. PMID- 29185125 TI - Measuring childhood cancer late effects: evidence of a healthy survivor effect. AB - INTRODUCTION: Given considerable focus on health outcomes among childhood cancer survivors, we aimed to explore whether survivor bias is apparent during long-term follow-up of childhood cancer survivors. METHODS: We identified all 1-year survivors of cancer diagnosed before 20 years of age in Denmark, Finland, Iceland, and Sweden. From the general population, we randomly sampled a comparison cohort. Study individuals were followed for hospitalizations for diseases of the gastroenterological tract, endocrine system, cardiovascular system, or urinary tract from the start of the cancer registries to 2010. We estimated cumulative incidence with death as competing risk and used threshold regression to compare the hazards of the diseases of interest at ages 20, 40, 60, and 75 years. RESULTS: Our study included 27,007 one-year survivors of childhood cancer and 165,620 individuals from the general population. The cumulative incidence of all four outcomes was higher for childhood cancer survivors during early adulthood, but for three outcomes, the cumulative incidence was higher for the general population after age 55 years. The hazard ratios (HRs) decreased for all outcomes with increasing age, and for two of the outcomes, the hazards were higher for the general population at older ages (endocrine diseases: age-specific HRs = 3.0, 1.4, 1.0, 0.87; Cardiovascular diseases: age-specific HRs = 4.1, 1.4, 0.97, 0.84). CONCLUSIONS: Our findings provide empirical evidence that survivor bias attenuates measures of association when comparing survivors with the general population. The design and analysis of studies among childhood cancer survivors, particularly as this population attains older ages, should account for survivor bias to avoid misinterpreting estimates of disease burden. PMID- 29185126 TI - Long-term outcome of congenital nephrotic syndrome after kidney transplantation in Japan. AB - BACKGROUND: Congenital nephrotic syndrome is difficult to manage, particularly the Finnish type (CNF), with patients experiencing severe edema, sepsis and thrombosis before kidney transplantation. Further, nephrosis and thrombosis remain problematic after transplantation. METHODS: Of 22 CNF patients managed at our hospital, 14 who underwent kidney transplantation were retrospectively studied. CNF was diagnosed according to standard criteria. RESULTS: The study population consisted of 3 males and 11 females. Mean gestation period was 36 +/- 1.4 weeks and mean birth weight was 2442 +/- 454 g (mean placenta to body weight ratio: 0.4). All patients started dialysis at 2.4 +/- 1.3 years and underwent kidney transplantation at 5.2 +/- 2.0 years. The kidneys were donated by the parents (n = 13), and cadaver (n = 2), including overlap. Mean follow-up period after transplantation was 14.3 +/- 8.9 years, and mean age at last observation was 19.5 +/- 8.5 years. Two patients had recurrent proteinuria after kidney transplantation; one underwent retransplantation following graft failure and eventually required dialysis, while the second had complete remission after intensive immunosuppressive therapy. There were no cases of thrombosis or serious infections. Mean eGFR at the time of last observation was 57.3 +/- 16.5 ml/min/1.73 m2, while mean height SD score was - 2.1 +/- 0.9 at the time of transplantation and - 1.5 +/- 1.5 at last observation. CONCLUSIONS: Long-term outcome in these 14 CNF patients showed satisfactory graft survival, improved height SD score, and favorable development. Although recurrent proteinuria after transplant was not predictive, it was associated with graft survival rate. PMID- 29185127 TI - Patient knowledge and adherence to maintenance hemodialysis: an International comparison study. AB - BACKGROUND: Non-adherence to hemodialysis (HD) is associated with increased morbidity and mortality. In this cross-sectional study, we compared correlates and rates of non-adherence between the US and Japan to determine if differences in patient knowledge about HD might account for international variation in adherence. METHODS: We evaluated 100 US and 116 Japanese patients on maintenance HD. Patient knowledge was scored based on the identification of their vascular access, dry weight, cause of kidney disease, and >= 3 phosphorus- and potassium rich foods. Patients were considered non-adherent if they missed > 3% of HD sessions in 3 months. RESULTS: 23% of the US and none of the Japanese patients were non-adherent. Using logistic regression, we found that in the US non adherence was more common in black patients [Odds ratio (OR) 3.98; 95% confidence interval (CI) 1.42-11.22], while high school graduates (OR 0.20; 95% CI 0.05 0.81) and those on the transplant waiting list (OR 0.25; 95% CI 0.083-0.72) were less likely to miss their treatments. There was no significant association between knowledge and non-adherence in the US. However, Japanese patients had significantly higher levels of HD knowledge than US patients after adjusting for age (p < 0.001). CONCLUSION: Age-adjusted HD knowledge was higher and non adherence rates were lower in Japan vs. the US. However, because of the unexpected finding of 100% adherence in Japan, we were unable to formally test whether knowledge was significantly associated with adherence across both countries. Further research is needed to understand the reasons behind the higher non-adherence rates in the US. PMID- 29185128 TI - Triphenylphosphine-based functional porous polymer as an efficient heterogeneous catalyst for the synthesis of cyclic carbonates from CO2. AB - A novel triphenylphosphine-based porous polymer (TPDB) with a high Brunauer Emmett-Teller (BET) surface area was synthesized through Friedel-Crafts alkylation of triphenylphosphine and alpha-dibromo-p-xylene. Then, the functional hydroxyl groups were successfully grafted onto the polymer framework by post modification of TPDB with 3-bromo-1-propanol (BP) and triethanolamine (TEA). The resulting sample TPDB-BP-TEA was characterized by various techniques such as FT IR, TG, SEM, EDS mapping, ICP-MS, and N2 adsorption-desorption. This new polymer was tested as the catalyst in the solvent-free cycloaddition reaction of CO2 with epoxides, which exhibited excellent performance, with high yield, selectivity, and stable recyclability for several catalytic cycles. The comparison experiment results demonstrate that the bromide ions and hydroxyl groups, as well as high surface area, are key factors in improving the catalytic activity of this new catalyst. PMID- 29185129 TI - Nostoc calcicola extract improved the antioxidative response of soybean to cowpea aphid. AB - BACKGROUND: Soybean (Glycine max (L.) Merr. cv. "Nam Dan") is one of the most valuable crops in agricultural production in Nghe An province (Vietnam). Our previous study revealed that extract of the cyanobacterium strain Nostoc calcicola HN9 expressed positive effect on growth and development, and raised soybean productivity (Tran et al. in Proceeding of Vietnam national conference of research on biology, Da Nang, 2016). We hypothesized that N. calcicola HN9 would improve the defense responses of G. max cv. "Nam Dan" to cowpea aphid (Aphis craccivora Koch)-a serious pest of leguminous crops. RESULTS: Infestation of A. craccivora caused oxidative stress in leaves of G. max cv. "Nam Dan". A strong generation of endogenous reactive oxygen species (ROS) such as superoxide anion radical (O 2.- ) and hydrogen peroxide (H2O2) resulted in the cellular damages in the aphid-infested leaves through high levels of injury percentage and lipid peroxidation. To protect from aphid attack themselves, soybean plants triggered the antioxidant defense systems, in which, enzymatic antioxidants such as superoxide dismutase (SOD, 1.15.1.1), catalase (CAT, 1.11.1.6) and GPx (EC 1.11.1.9) were strongly accumulated to reduce the toxic effects of ROS. Components of N. calcicola HN9 extract might strengthen the defensive capability of G. max cv. "Nam Dan" to cowpea aphid infestation via establishing the chemical constraints on oxidative stress. Under effect of cyanobacteria extract, generation of O 2.- and H2O2 was strictly limited, activities of SOD, CAT and GPx were remarkably accumulated in the aphid-infested leaves leading to a significant reduction of oxidative damages. CONCLUSIONS: Nostoc calcicola HN9 extract probably not only controlled the generation and effects of O 2.- and H2O2 but also augmented the accumulated activity of SOD, CAT and GPx in soybean leaves that allowed them to control oxidative stress, contributed to increase the resistance of G. max cv. "Nam Dan" to A. craccivora. The improvement of cyanobacteria extract on the antioxidative response of soybean "Nam Dan" to cowpea aphid can be a novel aspect to contribute to current knowledge regarding the soybean-aphid interaction. PMID- 29185130 TI - Increased lipid and protein oxidation and lowered anti-oxidant defenses in systemic lupus erythematosus are associated with severity of illness, autoimmunity, increased adhesion molecules, and Th1 and Th17 immune shift. AB - This study investigated nitro-oxidative stress in patients with systemic lupus erythematosus (SLE) in association with disease activity, immune-inflammatory biomarkers, and adhesion molecules. Two-hundred-four patients with SLE and 256 healthy volunteers were enrolled in this case-control study, which measured nitro oxidative stress biomarkers, including lipid peroxides (LOOH), advanced oxidation protein products (AOPPs), nitric oxide metabolites (NOx), sulfhydryl (-SH) groups, products of deoxyribonucleic acid (DNA)/ribonucleic acid (RNA) oxidative degradation, and total radical-trapping anti-oxidant parameter (TRAP). Also measured were anti-nuclear antibodies (ANAs), antibodies against double-stranded DNA (dsDNA), plasma levels of diverse cytokines, C-reactive protein, and adhesion molecules. LOOH (p < 0.001) and AOPP (p < 0.001) were significantly higher, while TRAP was significantly lower (p < 0.001) in SLE patients than in controls. AOPP and LOOH were significantly and positively associated with SLE disease activity index (SLEDAI) scores, anti-nuclear antibodies, and antibodies against double stranded DNA (anti-dsDNA) levels, while TRAP was significantly and inversely correlated with SLEDAI, ANA, and dsDNA antibody levels. There were significant positive associations between AOPP and LOOH and immune-inflammatory markers, indicating T helper (Th)-17 and Th1 bias and Th1 + Th17/Th2 ratio (p = 0.002 and p = 0.001, respectively). AOPP and LOOH (positively) and TRAP (inversely) were associated with adhesion molecule expression. A model predicting SLE was computed showing that, using LOOH, AOPP, NOx, adhesion molecules, and body mass index, 94.2% of the patients were correctly classified with a specificity of 91.5%. Increased nitro-oxidative stress takes part in the (auto)immune pathophysiology of SLE and modulates severity of illness and adhesion molecule expression.

AB - We report a simple method for electrospinning polymers onto flexible, insulating substrates by controlling the wettability of the substrate surface. Water molecules were adsorbed onto the surface of a hydrophilic polymer substrate by increasing the local humidity around the substrate. The adsorbed water was used as the ground electrode for electrospinning. The electrospun fibers were deposited only onto hydrophilic areas of the substrate, allowing for patterning through wettability control. Direct writing of polymer fiber was also possible through near-field electrospinning onto a hydrophilic surface. PMID- 29185131 TI - Nimbolide attenuate the lipid accumulation, oxidative stress and antioxidant in primary hepatocytes. AB - Nimbolide is a bioactive compound found in Azadirachta indica. This work was devised to investigate the potential effects of nimbolide on intracellular lipid deposition and its associated redox modulation in primary hepatocytes (Heps). Lipid accumulation was induced in Heps by supplementing 1 mM oleic acid for 24 h which was marked by significant accumulation of lipids. The results demonstrated that nimbolide can decrease intracellular cholesterol, free fatty acids and triglycerides. Nimbolide may also improve hepatocytes function through its antioxidant effects by inhibiting oxidative DNA damage and lipid peroxidation by curtailing the reactive oxygen species levels. Further it also restore the mitochondrial potential, improving the endogenous antioxidant levels such as GSH and antioxidant enzyme activities. Nimbolide increased (P < 0.05) liver X receptor-alpha (LXRalpha), peroxisome proliferator-activated receptor-gamma (PPARgamma) and sterol regulatory element-binding protein-1c (SREBP1c) gene expression in Heps. The biological significance of nimbolide may involve hypolipidemic effect, lipid peroxidation inhibition, DNA damage inhibition, ROS inhibition, restoring mitochondrial function, increases in GSH and SOD & CAT activities, and direct regulation of LXRalpha, PPARgamma and SREBP1c gene expression. Nimbolide may be used as effective lipid lowering compound and lipid deposition-induced Heps changes. PMID- 29185133 TI - A resistance exercise program improves functional capacity of patients with psoriatic arthritis: a randomized controlled trial. AB - The objective of this study is to assess the effectiveness of resistance training in patients with psoriatic arthritis (PsA). The study is a randomized controlled trial with 41 patients aged between 18 and 65 years with diagnosis of psoriatic arthritis (PsA). The patients were randomized into the following: intervention group (IG) and control group (CG). The IG underwent resistance exercise twice a week, for 12 weeks. The CG remained with the conventional drug therapy. The outcome measurements were the following: BASFI and HAQ-S for functional capacity, one maximum repetition test (1RM) for muscle strength, SF-36 questionnaire for general quality of life, and BASDAI and DAS-28 for disease activity. The evaluations were done by a blinded evaluator at baseline (T0) after 6 (T6) and 12 weeks (T12). At baseline, the groups were homogeneous regarding clinical and demographic characteristics. The IG significantly improved functional capacity measured by HAQ-S and disease activity measured by BASDAI, compared to CG, at week 12. Regarding quality of life, the IG improved the domains "pain" and "general health status" compared to CG (p < 0.05). There was improvement in muscular strength in almost all exercises in IG, except in the exercise for biceps. However, there were statistical differences between groups only on exercise "leg extension" in IG compared to CG. Resistance training is effective in improving functional capacity, disease activity, and quality of life of patients with psoriatic arthritis. The clinical improvements were not coupled to significant changes in muscular strength. PMID- 29185134 TI - When is the best moment to apply photobiomodulation therapy (PBMT) when associated to a treadmill endurance-training program? A randomized, triple blinded, placebo-controlled clinical trial. AB - Photobiomodulation therapy (PBMT) employing low-level laser therapy (LLLT) and/or light emitting diode therapy (LEDT) has emerged as an electrophysical intervention that could be associated with aerobic training to enhance beneficial effects of aerobic exercise. However, the best moment to perform irradiation with PBMT in aerobic training has not been elucidated. The aim of this study was to assess the effects of PBMT applied before and/or after each training session and to evaluate outcomes of the endurance-training program associated with PBMT. Seventy-seven healthy volunteers completed the treadmill-training protocol performed for 12 weeks, with 3 sessions per week. PBMT was performed before and/or after each training session (17 sites on each lower limb, using a cluster of 12 diodes: 4 * 905 nm super-pulsed laser diodes, 4 * 875 nm infrared LEDs, and 4 * 640 nm red LEDs, dose of 30 J per site). Volunteers were randomized in four groups according to the treatment they would receive before and after each training session: PBMT before + PBMT after, PBMT before + placebo after, placebo before + PBMT after, and placebo before + placebo after. Assessments were performed before the start of the protocol and after 4, 8, and 12 weeks of training. Primary outcome was time until exhaustion; secondary outcome measures were oxygen uptake and body fat. PBMT applied before and after aerobic exercise training sessions (PBMT before + PBMT after group) significantly increased (p < 0.05) the percentage of change of time until exhaustion and oxygen uptake compared to the group treated with placebo before and after aerobic exercise training sessions (placebo before + placebo after group) at 4th, 8th, and 12th week. PBMT applied before and after aerobic exercise training sessions (PBMT before + PBMT after group) also significantly improved (p < 0.05) the percentage of change of body fat compared to the group treated with placebo before and after aerobic exercise training sessions (placebo before + placebo after group) at 8th and 12th week. PBMT applied before and after sessions of aerobic training during 12 weeks can increase the time-to-exhaustion and oxygen uptake and also decrease the body fat in healthy volunteers when compared to placebo irradiation before and after exercise sessions. Our outcomes show that PBMT applied before and after endurance-training exercise sessions lead to improvement of endurance three times faster than exercise only. PMID- 29185135 TI - Disease-modifying treatments modulate myeloid cells in multiple sclerosis patients. AB - The role of myeloid cells in the pathogenesis of MS is determined by the polarization they acquire after activation, and mediated by release of extracellular vesicles (MVs). We assessed the effects of treatments for MS on activation and polarization of myeloid cells. MVs levels and markers of polarization of myeloid cells have been assessed at baseline and up to 6 months after the start of a MS treatment. Patients had higher levels of MVs than controls, and these increased significantly over 6 months under natalizumab. Interferon beta-1a significantly decreased M1 pro-inflammatory marker IL1beta and upregulated Trem2, a receptor important for debris clearance; both interferon beta-1a and fingolimod decreased pro-inflammatory marker IL6. Current treatments for MS significantly modulate myeloid cells activity. PMID- 29185137 TI - Chlorophyll fluorescence as a tool for nutrient status identification in rapeseed plants. AB - In natural conditions, plants growth and development depends on environmental conditions, including the availability of micro- and macroelements in the soil. Nutrient status should thus be examined not by establishing the effects of single nutrient deficiencies on the physiological state of the plant but by combinations of them. Differences in the nutrient content significantly affect the photochemical process of photosynthesis therefore playing a crucial role in plants growth and development. In this work, an attempt was made to find a connection between element content in (i) different soils, (ii) plant leaves, grown on these soils and (iii) changes in selected chlorophyll a fluorescence parameters, in order to find a method for early detection of plant stress resulting from the combination of nutrient status in natural conditions. To achieve this goal, a mathematical procedure was used which combines principal component analysis (a tool for the reduction of data complexity), hierarchical k means (a classification method) and a machine-learning method-super-organising maps. Differences in the mineral content of soil and plant leaves resulted in functional changes in the photosynthetic machinery that can be measured by chlorophyll a fluorescent signals. Five groups of patterns in the chlorophyll fluorescent parameters were established: the 'no deficiency', Fe-specific deficiency, slight, moderate and strong deficiency. Unfavourable development in groups with nutrient deficiency of any kind was reflected by a strong increase in F o and DeltaV/Deltat 0 and decline in phi Po, phi Eo delta Ro and phi Ro. The strong deficiency group showed the suboptimal development of the photosynthetic machinery, which affects both PSII and PSI. The nutrient-deficient groups also differed in antenna complex organisation. Thus, our work suggests that the chlorophyll fluorescent method combined with machine-learning methods can be highly informative and in some cases, it can replace much more expensive and time consuming procedures such as chemometric analyses.

The Barbados Blackbelly, a very interesting genetic resource, particularly well adapted to a harsh home environment in the humid tropics of the Caribbean. This review concerns this breed. It comprises aspects related to the breed history and standards and most importantly its reproductive and productive performances and gastrointestinal parasite tolerance in the Caribbean, North America and Central America and their introduction and use in crossbred trials in other regions of the tropics. PMID- 29185139 TI - Body weight change of Abergelle breed and Abergelle crossbred goats fed hay supplemented with different level of concentrate mixture. AB - The experiment was conducted at Sekota District using 36 intact yearling males of pure Abergelle breed and Abergelle crossbred goats (50%) with a mean live weight of 18.92 +/- 0.72 kg (mean +/- SE). The objective of the experiment was to evaluate the effect of different levels of concentrate mixture supplementation on feed intake, live weight gain, and economic gain of the breeds. Goats were blocked based on initial body weight and were randomly assigned to the dietary treatments. The experimental design was a 2 * 3 factorial in RCBD (randomized complete block design). The treatments included ad libitum feeding of local grass hay and supplementation with three levels (184, 368, and 552 g/day) of concentrate mixture. The experiment consisted of 90 days of feeding. Daily, total dry matter and CP (crude protein) intakes were affected by diet and genotype (P < 0.01). Significant decrease (P < 0.001) in hay intake was observed as the level of the supplement increased. Besides, substitution rate increased with increasing levels of supplementation. Average daily body weight gains were significantly impacted only by diet. Animals fed on 184 significantly lower weights, while nonsignificant difference was observed in live weight gain between 368 and 552 supplemented group. Supplementation of 368 concentrate mix significantly improved (P < 0.05) feed intake, daily weight gain, and feed conversion efficiency. Supplementation of 368 g/day had showed significantly higher net return for both goat breeds. However, the Abergelle breed was significantly better in net profit and sensitivity than the crossbreed. Both genotypes performed better with the diet containing 368 g/day than that with 184 and 552 g/day of concentrate supplementation. PMID- 29185136 TI - Molecular simulations of cellular processes. AB - It is, nowadays, possible to simulate biological processes in conditions that mimic the different cellular compartments. Several groups have performed these calculations using molecular models that vary in performance and accuracy. In many cases, the atomistic degrees of freedom have been eliminated, sacrificing both structural complexity and chemical specificity to be able to explore slow processes. In this review, we will discuss the insights gained from computer simulations on macromolecule diffusion, nuclear body formation, and processes involving the genetic material inside cell-mimicking spaces. We will also discuss the challenges to generate new models suitable for the simulations of biological processes on a cell scale and for cell-cycle-long times, including non equilibrium events such as the co-translational folding, misfolding, and aggregation of proteins. A prominent role will be played by the wise choice of the structural simplifications and, simultaneously, of a relatively complex energetic description. These challenging tasks will rely on the integration of experimental and computational methods, achieved through the application of efficient algorithms. Graphical abstract.

AB - Tsetse-related trypanosomosis threatens integrated crop-livestock production system in Ethiopia. Metekel zone is among the tsetse-infested areas in Ethiopia. Community-based tsetse fly and trypanosomosis control using targets was conducted from June 2011 to May 2012 in the zone. In coordination with the control project, a questionnaire survey was administered to assess the economic importance of the tsetse fly and trypanosomosis control conducted in the Zone. On average, there were 3 livestock deaths/household before control and this was decreased to 0.07 after control. This death was contributed from all possible livestock diseases. A household loss 4380 (95% CI = 4223.98-4541.79) EB (1 US$ = 17.9 EB) only due to the deaths of his/her livestock was reduced to 90.78 (95% CI = 89.15-92.42) EB after control. Morbidity of oxen in the study areas was significantly decreased by 70.7%. As a result, the monetary loss to rent for healthy draught oxen was decreased by 96.4%. When a household with one cattle harvest 10.9 quintals (1090 kg), his neighbor's household with ten cattle maximize his/her yield to about 50.5 quintals (5050 kg) of crops indicating that trypanosomosis has great economic impact in crop-livestock production system. As the community-based tsetse fly control approach is simple, cost effective, and appropriate for riverine tsetse species, we conclude that farmers can minimize the negative impact of tsetse flies and trypanosomosis in the tsetse-infested areas of African countries. PMID- 29185141 TI - Tip-cell behavior is regulated by transcription factor FoxO1 under hypoxic conditions in developing mouse retinas. AB - Forkhead box protein O1 (FoxO1) is a transcription factor and a critical regulator of angiogenesis. Various environmental stimuli, including growth factors, nutrients, shear stress, oxidative stress and hypoxia, affect FoxO1 subcellular localization and strongly influence its transcriptional activity; however, FoxO1-localization patterns in endothelial cells (ECs) during development have not been clarified in vivo. Here, we reported that FoxO1 expression was observed in three layers of angiogenic vessels in developing mouse retinas and that among these layers, the front layer showed high levels of FoxO1 expression in the nuclei of most tip ECs. Because tip ECs migrate toward the avascular hypoxic area, we focused on hypoxia as a major stimulus regulating FoxO1 subcellular localization in tip cells. In cultured ECs, FoxO1 accumulated into the nucleus under hypoxic conditions, with hypoxia also inducing expression of tip-cell-specific genes, including endothelial-specific molecule 1 (ESM1), which was suppressed by FoxO1 knockdown. Additionally, in murine models, EC specific FoxO1 deletion resulted in reduced ESM1 expression and suppressed tip cell migration during angiogenesis. These findings indicated roles for FoxO1 in tip-cell migration and that its transcriptional activity is regulated by hypoxia.

AB - Many medical centers are faced with a major challenge in making an accurate diagnosis of heparin-induced thrombocytopenia (HIT) and ensuring appropriate changes in management strategy in line with guideline recommendations. We report the initial and long-term impact and challenges of institution-wide changes in the diagnosis and management of HIT in the inpatient setting at an academic medical center. We established a HIT Task Force, consisting of a multidisciplinary team of non-malignant hematologists, nursing, pharmacist, pathology, blood bank and clinical lab informatics. Changes were implemented from 2011 to 2012. In 2013, testing for PF4 and SRA decreased by 37.5 and 85%, respectively. 100% of positive PF4 received an automatic hematology consult to guide management, leading to a 78% reduction in the use of direct thrombin inhibitors. Annual audits in the subsequent years demonstrated increasing testing for HIT due to changes in the electronic ordering system. Through continuous monitoring, these shortfalls were detected and intervene early on with continued success. The implementation of a centralized hospital-wide protocol via a multidisciplinary task force that coordinates testing and treatment of patients suspected of having HIT led to a substantial reduction in PF4 and SRA testing, as well as use of DTIs, resulting in a safe and cost-effective approach for the diagnosis and treatment of HIT. Our study highlights the important of continuous monitoring to maintain the improvements made. Despite our initial success, annual re-auditing allowed for early detection of challenges, which then allowed appropriate early intervention. PMID- 29185143 TI - Association between short- and medium-term air pollution exposure and risk of mortality after intravenous thrombolysis for stroke. AB - The exposure to air pollutants may increase both incidence and mortality of stroke. We aimed to investigate the association of short- and medium-term exposure to particulate matter (PM) and nitrogen dioxide (NO2) with the outcome of intravenous thrombolysis (IVT) for stroke. We conducted a retrospective analysis based on data prospectively collected from 944 consecutive IVT-treated stroke patients. The main outcome measure was 3-month mortality. The secondary outcome measures were causes of neurological deterioration (>= 1 NIHSS point from baseline or death < 7 days), including intracerebral hemorrhage, cerebral edema (CED), and persistence or new appearance of hyperdense cerebral artery sign. In the adjusted model, higher PM2.5 and PM10 values in the last 3 days and 4 weeks before stroke were independently associated with higher mortality rate [hazard ratio (HR) 1.014, 95% confidence intervals (CI) 1.005-1.024, p = 0.003; HR 1.079, 95% CI 1.055-1.103, p = 0.001; HR 1.019, 95% CI 1.005-1.032, p = 0.008; and HR 1.015, 95% CI 1.004-1.027, p = 0.007; respectively]. Higher PM2.5 and PM10 values in the last 4 weeks were associated with higher CED rate [odd ratio (OR) 1.023, 95% CI 1.007-1.040, p = 0.006; and OR 1.017, 95% CI 1.003-1.032, p = 0.021; respectively]. No significant association between PM or NO2 and other causes of neurological deterioration was observed. Higher exposure to PM in the last 3 days and 4 weeks before stroke may be independently associated with 3-month mortality after IVT. Higher exposure to PM in the last 4 weeks before stroke may also be independently associated with CED after IVT. PMID- 29185144 TI - Bond strength of adhesive systems to sound and demineralized dentin treated with bioactive glass ceramic suspension. AB - OBJECTIVE: The objective of this study was to evaluate the effect of a Biosilicate(r), associated with dentin adhesive system, on microtensile bond strength (MUTBS) to sound and demineralized dentin. MATERIALS AND METHODS: Eighty sound-extracted molars had their middle occlusal dentin exposed. In forty teeth, dentin was artificially demineralized (pH cycling). Sound and demineralized dentin teeth were separated into four groups (n = 10), according to the substrate treatment before restoration: Group 1-total-etching adhesive Adper TM Single bond 2 (ASB) + Biosilicate(r), Group 2-ASB (without Biosilicate(r)), Group 3-AdheSE self-etching adhesive system (AdSE) + Biosilicate(r), and Group 4-AdSE (without Biosilicate(r)). Each tooth was restored with a hybrid composite and stored in water at 37 degrees C for 6 months. After water aging, teeth were cut in sticks (~ 1 mm2 cross-sectional area) and all samples were submitted to MUTBS test. The fracture modes of the samples were analyzed by stereomicroscopy. The representatively fractured samples were observed by scanning electron microscopy. Representative samples of each group were analyzed on energy dispersive X-ray spectrometry (EDX). The MUTBS and Ca-P ratio values were analyzed by 2-way ANOVA, Bonferroni, and Tukey test, respectively, p < .05. RESULTS: ASB + Biosilicate(r) presented the highest MUTBS values (p < .05), and lowest MUTBS values (p < .05) were found in AdSE Group. There was no statistical difference (p < .05) on MUTBS when substrates were compared, except for Group 2. The fracture pattern analysis showed prevalence of adhesive fractures in all groups. CONCLUSION: Biosilicate(r) enhanced bond strength of self-etching and etch-and-rinse adhesives to sound and demineralized dentin. CLINICAL RELEVANCE: Bioactive glass ceramic suspension could be recommended to be used to improve the dentin bond strengths of the total etching and self-etching adhesives after acid-etching and priming. PMID- 29185145 TI - Development of a novel bioactive glass for air-abrasion to selectively remove orthodontic adhesives. AB - OBJECTIVES: To develop a novel, bioactive glass for removing residual orthodontic adhesive via air-abrasion, following bracket debonding, and to evaluate its effectiveness against a proprietary bioactive glass 45S5(SylcTM)-air-abrasion, and a slow-speed tungsten carbide (TC) bur. MATERIALS AND METHODS: Three glasses were prepared and their bioactivity was proved. One novel glass (QMAT3) was selected due to its appropriate hardness, lower than that of enamel/45S5(SylcTM). Sixty extracted human premolars were randomly assigned to adhesive removal using: (a) QMAT3-air-abrasion, (b) 45S5(SylcTM)-air-abrasion, and (c) TC bur, which were further subdivided (n = 10) based on the adhesive used (Transbond XTTM or Fuji Ortho LCTM). Enamel roughness was assessed using scanning electron microscopy (SEM) and non-contact profilometry before bracket bonding, after removing residual adhesive following bracket debonding and after polishing. RESULTS: QMAT3 formed apatite faster (6 h) than 45S5(SylcTM) (24 h) in Tris solution. QMAT3-air abrasion gave the lowest enamel roughness (Ra) after removing the adhesives. SEM images showed a pitted, roughened enamel surface in the TC bur group and to a lesser extent with 45S5(SylcTM), while a virtually smooth surface without any damage was observed in the QMAT3-air-abrasion group. The time taken for adhesive removal with QMAT3 was comparable to 45S5(SylcTM) but was twice as long with the TC bur. CONCLUSIONS: QMAT3-air-abrasion is a promising technique for selective removal of adhesives without inducing tangible enamel damage. CLINICAL RELEVANCE: A novel bioactive glass has been developed as an alternative to the use of TC burs for orthodontic adhesive removal. PMID- 29185146 TI - Lack of association between ENAM gene polymorphism and dental caries in primary and permanent teeth in Czech children. AB - OBJECTIVES: The enamelin gene (ENAM) polymorphism (rs12640848) was recently associated with dental caries in primary teeth in Polish children. The aims of the present study were to prove this association in primary dentition and to find a possible effect of this variant on caries development in permanent dentition in Czech children. MATERIALS AND METHODS: This study comprised 905 Czech children. Totally, 187 children aged 2-6 years with primary dentition [78 healthy subjects (with decayed/missing/filled teeth, dmft = 0) and 109 patients with early childhood caries (ECC; dmft >= 1)] were included in this case-control study. In addition, 177 subjects aged 13-15 years without caries (DMFT = 0) and 541 children with dental caries (DMFT >= 1) in permanent dentition were selected from the ELSPAC study. Genotype determination of the ENAM polymorphism (rs12640848) was based on the TaqMan method. RESULTS: No significant differences in the allele or genotype frequencies between the caries-free children and those affected by dental caries were observed in both primary and permanent dentitions. CONCLUSIONS: Lack of association between the ENAM polymorphism (rs12640848) and dental caries in Czech children was detected. CLINICAL RELEVANCE: Although ENAM is considered as a candidate gene for dental caries, the presence of the ENAM variant (rs12640848) cannot be used as a risk factor of this multifactorial disease in the Czech population. PMID- 29185147 TI - Predicting pituitary stalk position by in vivo visualization of the hypothalamo hypophyseal tract in craniopharyngioma using diffusion tensor imaging tractography. AB - The pituitary stalk (PS) is crucial to endocrine function and water-electrolyte equilibrium. Preservation of the PS during craniopharyngioma (CP) surgery is critical; however, in a pathological state, it is difficult to identify. The hypothalamo-hypophyseal tract (HHT) connects the hypothalamus and the posterior pituitary gland and projects through the PS. Thus, visualization of the HHT can help locate the PS. Preoperative visualization of the neural fasciculus has been widely achieved using diffusion tensor imaging (DTI) tractography. Therefore, this study evaluated the use of DTI tractography to identify and characterize the human HHT. We used DTI tractography to track the HHT in 10 patients with CP and compared the location of the tract with the intraoperative view of the PS in these patients. We successfully tracked the HHT in nine patients, indicating that delineating and quantifying the tracked HHT using this method is feasible. In addition, we found that the tract was consistent with the intraoperative view of the PS in seven out of eight patients (87.50%). Finally, we found that the mean number of tracts was 7.11 +/- 12.28, the mean fractional anisotropy (FA) was 0.11 +/- 0.04, and the mean tract length was 24.22 +/- 9.39 mm. Taken together, our results demonstrate that the HHT can be visualized and characterized with DTI even in a clinical application, which may aid in preoperative identification of the PS. Characterization of the tracked HHT with this technique could also be used to advance our understanding of the HHT. PMID- 29185149 TI - Laparoscopic Treatment of Median Arcuate Ligament Syndrome: Analysis of Long-Term Outcomes and Predictive Factors. AB - BACKGROUND: Laparoscopic arcuate ligament release has been demonstrated a valid therapeutic option for arcuate ligament syndrome. Nevertheless, long-term follow up and predictive factors have not been described for this treatment. METHODS: Clinical and surgical data and short- and long-term outcomes together with the impact of the degree of stenosis of the celiac trunk were analyzed in 13 consecutive patients who underwent laparoscopic arcuate ligament release between 2001 and 2013. RESULTS: Thirteen patients (12 F/1 M) underwent surgery. The median age was 32 years old, and their mean body mass index was 20.7 (range 14.7 25). The 13 patients presented with intense postprandial abdominal pain. Ten cases were associated with weight loss. The median duration of symptoms was 24 months (range 2-240). Three patients presented symptoms associated with superior mesenteric artery syndrome. Median operative time was 120 min (range 90-240), and there were no conversions to open surgery. Median hospital stay was 3 days (range 2-14). Over a median follow-up of 117 months (range 45-185), nine patients had excellent results although two required endovascular procedures at 70 and 24 months after surgery. Four patients (30.7%) experienced poor outcomes. When we analyzed the impact of the degree of occlusion of the celiac trunk, we observed that in patients with severe occlusion (> 70%), better results were obtained, with complete resolution of symptoms in 71% of cases. CONCLUSION: Laparoscopic arcuate ligament release constitutes an excellent treatment for arcuate ligament syndrome. The degree of occlusion of the celiac trunk may be a factor predictive of long-term outcomes. PMID- 29185148 TI - Therapeutic prospects of microRNAs in cancer treatment through nanotechnology. AB - MicroRNAs (miRNAs) represent a new class of diagnostic and prognostic biomarker as well as new therapeutic targets in cancer therapy. miRNAs are gaining significant interest due to extensive advancements in knowledge since their discovery and, more recently, their translational application as therapeutic moieties and targets in the management of disease. miRNAs used in the treatment of cancer would position them as a new class of emerging therapeutic agents. Indeed, numerous candidate miRNAs have been identified as having therapeutic application in the treatment of cancer, but there is still much to learn about how to transform these into effective, patient-compliant, and targeted drug delivery systems. In this mini review, we discuss the utility and potential of nanotechnology in miRNA formulation and delivery with particular emphasis on cancer, including their role in conferring multidrug resistance and metastatic capacity. This review benefits both the formulation and biological scientists in understanding and exploring the new vistas of miRNA delivery using nanotechnology in the cancer clinically. PMID- 29185150 TI - Key Ingredients-Target Groups, Methods and Messages, and Evaluation-of Local Level, Public Interventions to Counter Stigma and Discrimination: A Lived Experience Informed Selective Narrative Literature Review. AB - A proliferation of recent literature provides substantial direction as to the key ingredients-target groups, messages and methods, and evaluation-of local-level, public interventions to counter stigma and discrimination. This paper provides a selective narrative review of that literature from the perspective or standpoint of anti-stigma experts with lived experience of mental distress, the key findings of which have been synthesised and presented in diagrammatic overviews (infographics). These are intended to guide providers in planning, delivering and evaluating lived experience-directed local-level, public interventions to counter stigma and discrimination in accord with current best practice. PMID- 29185151 TI - The Use of Access Groups for Engagement in Community Mental Health Post Hospitalization. AB - This paper describes a novel approach to engaging psychiatric patients in care after discharge from inpatient or ER treatment. The Access Group model provides rapid, flexible, high-volume intake for up to 20 patient referrals per day. Patients are scheduled for intake by referring hospital clinicians using an online scheduling software and can be seen within 1-3 days of hospital discharge. Access allows flexibility, easy rescheduling, and limited wait time. At intake, patients and family members participate in a structured group intake procedure from which they are scheduled for follow-up psychiatry, therapy, and social work appointments. Same-day appointments are available for urgent needs. Initial evidence suggests that the Access Group model is effective at providing rapid access to and engagement in care, and is acceptable to patients. Generalizability and funding approaches for the model are discussed. PMID- 29185152 TI - Mental Health in China: Stigma, Family Obligations, and the Potential of Peer Support. AB - Some people with mental illness in China do not receive treatment. We explored how stigma and familial obligation influenced accessibility of social support for patients with depression in China and the potential acceptability of peer support programs. Semi-structured qualitative interviews were conducted with five psychiatrists and 16 patients receiving care for depression from a large psychiatric hospital in Jining, Shandong Province of China. Patients with mental illness reported barriers that prevented them from (a) receiving treatment and (b) relying on informal social support from family members, including stigma, somatization, and community norms. Circumventing these barriers, peer support (i.e., support from others with depression) was viewed by patients as an acceptable means of exchanging information and relying on others for support. Formative research on peer support programs to examine programming and activities may help reduce the burden of unmet mental health care needs in China. PMID- 29185153 TI - A Doctor is in the House: Stakeholder Focus Groups About Expanded Scope of Practice of Community Psychiatrists. AB - We sought to understand stakeholder perspectives on barriers to metabolic screening for people with severe mental illness. We additionally assessed the feasibility of expanding psychiatrists' scope of practice to include treatment of cardiometabolic abnormalities. We conducted four focus groups among patients with severe mental illness, community psychiatrists, primary care providers, and public health administrators. Focus group transcripts were thematically analyzed. Three domains emerged: challenges with patient navigation of the complex health care system, problem list prioritization difficulties, and concern that treatment of cardiometabolic abnormalities were beyond the scope of practice of psychiatrists. Stakeholders agreed that navigating the health care system was challenging for this population and led to undertreatment of cardiometabolic risk factors. Expansion of psychiatrists' scope of practice within community mental health appears acceptable to patients and may be a mechanism to improve cardiometabolic care among people with severe mental illness. PMID- 29185154 TI - Counseling on Access to Lethal Means (CALM): An Evaluation of a Suicide Prevention Means Restriction Training Program for Mental Health Providers. AB - This paper evaluates the effectiveness of the Counseling on Access to Lethal Means (CALM) suicide prevention program. CALM trains mental health providers how to counsel suicidal individuals and those who support them on mean restriction during times of crisis. Pre/post/3-month follow-up assessments measured knowledge of lethal means, confidence and comfort in discussing means restriction (self efficacy), and future intentions to counsel clients on means restriction. Change in the number of clients receiving lethal means counseling was also assessed. All constructs increased significantly at posttest. Confidence and counseling intentions were sustained at follow-up and significantly more clients received means counseling in the 3 months following the CALM training. Knowledge and comfort levels decreased at follow-up but not to pre-training levels. CALM is effective at increasing mental health professionals' comfort, knowledge, and frequency of talking about means restriction with clients. an effective means restriction training program. A template to assess clients for suicidality and lethal means access and booster sessions are recommended to further sustain effects. PMID- 29185155 TI - Successful treatment of follicular lymphoma with second-generation tyrosine kinase inhibitors administered for coexisting chronic myeloid leukemia. AB - Tyrosine kinase inhibitors (TKIs) are standard therapy for chronic myeloid leukemia (CML). However, the effects of these agents on mature B cell lymphoma are not well known. We describe a 50-year-old man who was diagnosed with CML in the chronic phase and treated with imatinib. After 3 years of imatinib therapy that achieved a complete cytogenetic response of CML, he developed Philadelphia negative follicular lymphoma (FL). Rituximab monotherapy induced a partial response of FL, and he subsequently achieved a major molecular response (MMR) of CML. Three years later, however, the MMR was lost, followed by the progression of FL. Imatinib was switched to nilotinib for the treatment of CML, while we chose watchful waiting for FL. He achieved MMR again under treatment with nilotinib for 8 months including one month of substitutional use of dasatinib due to adverse events, but thereafter nilotinib was switched to bosutinib due to hyperbilirubinemia. With the administration of second-generation TKIs (2G-TKIs) for a total of 18 months, he achieved a complete response to FL without antilymphoma treatment. This is the first report to suggest that 2G-TKIs may have direct or indirect effects on FL.

AB - Pulmonary alveolar proteinosis (PAP) is a rare disorder that is characterized by the excessive accumulation of surfactant-like materials in the alveoli, leading to hypoxemic respiratory failure. We describe two Japanese infants with PAP associated with hypogammaglobulinemia and monocytopenia. These patients may have underlying primary immunodeficiency (PID) and were successfully treated with allogeneic hematopoietic stem cell transplantation (HSCT). This report indicates that allogeneic HSCT may provide a curative treatment for PAP associated with PID.

PMID- 29185158 TI - Delivery of expression constructs of secreted frizzled-related protein 4 and its domains by chitosan-dextran sulfate nanoparticles enhances their expression and anti-cancer effects. AB - In malignant mesothelioma (MM) cells, secreted frizzled-related protein 4 (SFRP4) expression is downregulated by promoter methylation. In this study, we evaluated the effect of encapsulated chitosan-dextran (CS-DS) nanoparticle formulations of SFRP4 and its cysteine-rich domain (CRD) and netrin-like domain (NLD) as means of SFRP4-GFP protein delivery and their effects in JU77 and ONE58 MM cell lines. CS DS formulations of SFRP4, CRD, and NLD nanoparticles were prepared by a complex coacervation technique, and particle size ranged from 300 nm for empty particles to 337 nm for particles containing the proteins. Measurement of the zeta potential showed that all preparations were around 25 mV or above, suggesting stable formulation and good affinity for the DNA molecules. The CS-DS nanoparticle formulation maintained high integrity and entrapment efficiency. Gene delivery of SFRP4 and its domains showed enhanced biological effects in both JU77 and ONE58 cell lines when compared to the non-liposomal FUGENE(r) HD transfection reagent. In comparison to the CRD nanoparticles, both the SFRP4 and NLD nanoparticles significantly reduced the viability of MM cells, with the NLD showing the greatest effect. The CS-DS nanoparticle effects were observed at an earlier time point and with lower DNA concentrations. Morphological changes in MM cells were characterized by the formation of membrane-associated vesicles and green fluorescent protein expression specific to SFRP4 and the NLD. The findings from our proof-of-concept study provide a stepping stone for further investigations using in vivo models. PMID- 29185159 TI - The effect of estradiol, testosterone, and human chorionic gonadotropin on the proliferation of Schwann cells with NF1 +/- or NF1 -/- genotype derived from human cutaneous neurofibromas. AB - Dermal neurofibromas are the hallmarks of neurofibromatosis type 1 (NF1). Neurofibromas harbor Schwann cells with two different genotypes: Schwann cells which carry the germline mutation and a healthy NF1 allele (NF1 +/-), and a subpopulation of Schwann cells which harbor the so-called second hit leading to inactivation of both NF1 alleles (NF1 -/-). The second hit in the NF1 gene of Schwann cells is considered to be the initial step in the development of neurofibromas. Dermal neurofibromas typically start to grow in puberty, and their number and size increase during pregnancy, indicating hormone responsiveness. This is the first study to address the effect of human chorionic gonadotropin (hCG) on the proliferation of human NF1 +/- and NF1 -/- Schwann cells in vitro. In addition, the effects of estradiol and testosterone were also investigated. The results showed that NF1 -/- Schwann cells were more sensitive to estradiol, testosterone, and human chorionic gonadotropin than NF1 +/- cells. Specifically, the proliferation of NF1 -/- Schwann cells was increased by up to 99, 110, and 170% compared to vehicle control when treated with estradiol, testosterone, and hCG, respectively. Interestingly, no effect of estradiol, testosterone, or hCG on the proliferation of the cells with NF1 +/- genotype was observed. To conclude, the somatic second hit in the NF1 gene sensitizes Schwann cells to sex hormones resulting in a highly increased proliferation. Our results highlight the significance of sex hormones in the regulation of neurofibroma growth. PMID- 29185160 TI - Exogenous growth factors enhance the expression of cola1, cola3, and Elastin in fibroblasts via activating MAPK signaling pathway. AB - Exogenous growth factors could accelerate the process of wound healing. However, the underlying mechanisms have not been clearly clarified. The aim of the present study was to investigate the effect of epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF) on the expression of type I collagen (cola1), type III collagen (cola3), and Elastin in fibroblasts, which are widely expressed in fibroblasts and promote the function of fibroblasts. We measured the levels of cola1 and cola3 in human fibroblast cells cultured in medium containing EGF or bFGF at concentrations ranging from 0.1 to 1000 MUg/L by Western blotting and RT PCR assays, and found that EGF or bFGF enhanced the expression of cola1 and cola3 in a concentration-dependent manner. We further discovered that after stimulation with EGF or bFGF in human fibroblast cells, mitogen-activated protein kinases (MAPK) family members were generally activated, whose expression trend was consistent with that of cola1, cola3, and Elastin. In summary, in this study, we uncovered that exogenous growth factors enhance the expression of cola1, cola3, and Elastin, which is probably regulated via activating MAPK signaling pathway. PMID- 29185161 TI - Exercise therapy and autonomic function in heart failure patients: a systematic review and meta-analysis. AB - A large body of evidence exists indicating that autonomic imbalance is characteristic of heart failure, with several parameters of autonomic function associated with adverse clinical outcomes. The aim of this systematic review and meta-analysis was to investigate the effects of exercise training on parameters of autonomic function in patients with heart failure and where possible quantify the size of the effect. We conducted database searches (PubMed, EMBASE and Cochrane Trials Register to 31 March 2017) for exercise-based rehabilitation trials in heart failure; using search terms, exercise training, autonomic function, heart rate recovery, heart rate variability and muscle sympathetic nerve activity. Pooled data indicated a statistically significant increase in heart rate recovery at 1 min (HRR1) in exercise compared to control groups, mean difference 5.90 bpm (95%CI 5.12, 6.69; p < 0.00001). Pooled data also indicated that exercise training improved the short-term heart rate variability (HRV) parameters of root mean square of successive differences between normal heart beats (RMSSD (ms)) [mean difference 10.44 (95%CI 0.60, 20.28, p = 0.04)] and high frequency normalised units (HFnu) [mean difference 7.72 (95%CI 3.32, 12.12, p = 0.0006), which are predominantly reflective of parasympathetic activity. Analyses also indicated a statistically significant decrease in muscle sympathetic nerve activity (MSNA) bursts/minute (mean difference - 11.09 (95%CI - 16.18, - 6.00; p < 0.0001) and MSNA bursts/100 heart beats (mean difference - 15.44 (95%CI - 20.95, -9.92; p < 0.00001) in exercise groups compared to controls. With improvements in HRR, HRV and MSNA, exercise training appears to facilitate an improvement in parasympathetic tone and reduction in sympathetic activity. PMID- 29185162 TI - The effect of Medicaid payer status on patient outcomes following repair of massive rotator cuff tears. AB - BACKGROUND: The influence of socioeconomic status and insurance type has not been studied extensively for RCR, particularly not in the high risk massive RCT population. The purpose of this study is to identify relationships between Medicaid payer status and patient outcomes following massive RCR. METHODS: A retrospective review of shoulder surgery database identified 29 patients undergoing massive rotator cuff repair. Patients were stratified based on insurance type into two cohorts, Medicaid (14 patients) and non-Medicaid (15 patients). Missed routine follow-up appointments and comorbidities were recorded and compared between groups. Group comparisons were made for pre- and postoperative patient-reported and functional outcomes. Outcome scores included American Shoulder and Elbow Shoulder Score (ASES), the Penn Shoulder Score, and the Subjective Shoulder Value (SSV). A p value of < 0.05 was considered significant for all statistical analyses. RESULTS: Medicaid patients were on average 7.1 years younger than non-Medicaid patients (49.8 vs. 56.9 years, respectively), and remaining demographics were comparable between groups. Preoperative patient-reported outcomes were only significantly different for ASES and ASES pain (p = 0.010, 0.037). There was excellent average improvement for Medicaid patients but no significant differences compared to non-Medicaid patients for ASES (p = 0.630), PENN scores (p = 0.395), and SSV (p = 0.198). Medicaid patients also had a higher number of missed and canceled appointments (28%) compared to non-Medicaid patients (18%). CONCLUSION: Medicaid coverage will expand to millions of uninsured Americans under current healthcare reform. Medicaid patients with massive RCT appear to significantly improve with surgical treatment. PMID- 29185163 TI - Cardiopulmonary bypass for pediatric cardiac surgery. AB - The management of cardiopulmonary bypass for pediatric cardiac surgery is more challenging than that in adults due to the smaller size, immaturity, and complexity of the anatomy in children. Despite major improvements in cardiopulmonary bypass, there remain many subjects of debate. This review article discusses the physiology of cardiopulmonary bypass for pediatric and congenital heart surgery, including topics related to hemodilution, hypothermia, acid-base strategies, inflammatory response, and myocardial protection. PMID- 29185164 TI - Extracellular chromone derivatives in cell cultures of Pimpinella anisum. Influence of elicitation with methyl jasmonate and 2beta-methyl cyclodextrins. AB - OBJECTIVES: To explore the potentiality of undifferentiated Pimpinella anisum L. cell cultures for the production of secondary metabolites by means of elicitation. RESULTS: Two chromone compounds were secreted to the medium of undifferentiated cultures of P. anisum: 4-methoxyfuro[3,2-g]chromen-7-one, known as bergapten, which is constitutive to anise, and 5-hydroxy-7-methoxy-2 methylchromen-4-one, the rare chromone eugenin, not yet described in P. anisum. Caffeoyl quinic acid species were also identified in the biomass. Elicitation with methyl jasmonate enhanced chromone accumulation in the medium and stimulated phenolic acid metabolism in the biomass (11 mg caffeoyl quinic acids g-1 DW cells). The application of 2,6-dimethyl-beta-cyclodextrins to cultures led to an intense accumulation of chromones, with nearly 10 mg l-1 bergapten and 150 mg l-1 eugenin being accumulated extracellularly after optimal elicitation conditions. CONCLUSIONS: The significant amounts of eugenin obtained in the anise cultures and the stability of production over long periods of time can be of interest for its biotechnological production and for future studies on biosynthesis regulation. PMID- 29185165 TI - Immune parameters associated with mortality in the elderly are context-dependent: lessons from Sweden, Holland and Belgium. AB - The pioneering Swedish OCTO/NONA-Immune longitudinal studies led by Anders Wikby in Jonkoping in the 1990s established a cluster of simple baseline immune parameters associated with excess mortality in 85 year-old non-institutionalized individuals over 2, 4 and 6-year follow-up. We dubbed this cluster the "Immune Risk Profile" (IRP) consisting of poor proliferative responses of peripheral blood mononuclear cells to T cell mitogens, accumulations of CD8+ CD28- T-cells resulting in an inverted CD4:8 ratio, decreased amounts of B-cells, and seropositivity for Cytomegalovirus (CMV). The concept of the IRP has since been applied by others to many different populations in different circumstances and at different ages, but in general without specifically establishing whether the same risk factors were relevant in the tested subjects. However, our own later studies showed that risk factors in aged populations from The Netherlands and Belgium were markedly different, indicating that the IRP cannot simply be transferred between populations. Moreover, there was a striking sex difference in the Belgian study, which was the only one large enough to include sufficient numbers of old men. The reasons for these marked differences between populations which one might have assumed a priori to be quite similar to one another are not clear, and many candidates can be speculated upon, but the important lesson is that there is a marked context-dependency of immune biomarkers of ageing, suggesting that IRPs cannot be assumed to be identical in different populations. PMID- 29185166 TI - Echinacoside, a phenylethanoid glycoside from Cistanche deserticola, extends lifespan of Caenorhabditis elegans and protects from Abeta-induced toxicity. AB - Cistanche deserticola has been found to exert protection against aging and age related diseases, but mechanisms underlying its longevity effects remain largely unclear. Here, the multicellular model organism Caenorhabditis elegans was employed to identify lifespan extending and protective effects against beta amyloid (Abeta) induced toxicity by echinacoside (ECH), a phenylethanoid glycoside isolated from C. deserticola. Our results showed that ECH extends the mean lifespan of worms and increases their survival under oxidative stress. Levels of intracellular reactive oxygen species and fat accumulation were also significantly suppressed by ECH. Moreover, ECH-mediated lifespan extension was found to be dependent on mev-1, eat-2, daf-2, and daf-16, but not sir-2.1 or hsf 1 genes. Furthermore, ECH triggered DAF-16 nuclear localization and upregulated two of its downstream targets, sod-3 and hsp-16.2. In addition, ECH significantly improved the survival of CL4176 worms in response to proteotoxic stress induced by Abeta protein aggregation. Collectively, these findings suggested that reactive oxygen species scavenging, dietary restriction, and insulin/insulin-like growth factor signaling pathways could be partly involved in ECH-mediated lifespan extension. Thus, ECH may target multiple longevity mechanisms to extend lifespan and have a potency to prevent Alzheimer's disease progression.

AB - Association of congenital cytomegalovirus (CMV) infection with autism spectral disorder (ASD) has been suggested since 1980s. Despite the observed association, its role as a risk factor for ASD remains to be defined. In the present review, we systematically evaluated the available evidence associating congenital CMV infection with ASD using PubMed, Web of Science, Cochrane Library, and Embase databases. Any studies on children with CMV infection and ASD were evaluated for eligibility and three observational studies were included in meta-analysis. Although a high prevalence of congenital CMV infection in ASD cases (OR 11.31, 95% CI 3.07-41.66) was indicated, too few events (0-2 events) in all included studies imposed serious limitations. There is urgent need for further studies to clarify this issue.

PMID- 29185169 TI - How predictive are sex and empathizing-systemizing cognitive style for entry into the academic areas of social or physical sciences? AB - Based on the Empathizing-Systemizing (E-S) theory, it was hypothesized that the underrepresentation of female students in the physical sciences and the underrepresentation of males in the social sciences relates to differences in E-S cognitive style between the sexes. This hypothesis was tested in 115 physical science students and 155 social science students from a university in the Netherlands. The students completed visuospatial tests and the systemizing quotient-revised (SQ-R) as measures for systemizing, and a Cartoon Prediction test and the empathy quotient (EQ) as measures for empathizing. Independent of sex, the physical science students scored significantly lower than social science students on EQ (with large effect size) and 'brain type' that represents the standardized difference score between EQ and SQ-R (with large effect size). Physical science students, furthermore, scored significantly higher on the Cartoon Prediction task and one of the visuospatial tasks; however, these effects were only small of size. Unlike the scores on the SQ-R and the performance tests, the 'brain type' score of the EQ and SQ-R questionnaires was a good predictor of entry into social or physical sciences. Interestingly, the typical sex differences in more empathizing and less systemizing in females compared to males were only small for EQ and 'brain type', and absent for the SQ-R and the performance tests. This study only partially confirms the E-S theory, because typical sex differences were only minor in this selective sample and only the self-report measures predicted academic area in the absence of a role for sex.

PMID- 29185170 TI - Influence of time-of-day on joint Navon effect. AB - The shared attention theory suggests that people devote greater cognitive resources to those features co-attended simultaneously with others, determining better performance in several types of tasks. When co-actors performed a go/no-go Navon task attending different features of target letters, the performance was impaired, reflecting a joint Navon effect (the representation of a co-actor's attentional focus made it more difficult to select and apply one's own focus of attention), probably due to asynchronous co-attention with a decrease in cognitive resources involved. Researches in chronobiology and chronopsychology demonstrated that not only selective attention (involved in a Navon task), but also cognitive resources have a daily fluctuations, mainly paralleling the circadian rhythm of body temperature (i.e. increasing values from the morning to evening with a subsequent decline in the night). The study was conducted to assess whether the presence of joint attention, as measured by the joint Navon effect, was influenced by the time-of-day. Sixteen pairs of participants sitting next to each other were required to respond to the identity letters in a go/no-go Navon task twice: in the morning (09:00-10:00) and early afternoon (13:00-14:00). The results showed a joint Navon effect in the morning session only, suggesting that joint attention was affected by the time-of-day effect on cognitive resources.

AB - BACKGROUND: The homeless population in the United States is aging. Aging associated comorbidities are associated with increased symptoms. OBJECTIVE: To describe the prevalence of symptoms among older homeless-experienced adults, analyze factors associated with moderate-high physical symptom burden, and identify symptom clusters. DESIGN: Cross-sectional analysis within longitudinal cohort study. PARTICIPANTS: Using population-based sampling from shelters, meal programs, encampments, and a recycling center in Oakland, CA, we recruited homeless adults aged >= 50 for a longitudinal cohort. This study includes participants who participated in the 18-month follow-up visit. MAIN MEASURES: We assessed physical symptoms using the Patient Health Questionnaire-15 (PHQ-15); psychological symptoms using the Center for Epidemiologic Studies Depression Scale (CES-D), Primary Care PTSD Screen (PC-PTSD), and psychiatric section of the Addiction Severity Index (ASI); loneliness using the Three-Item Loneliness Scale; and regret using a six-item regret scale. KEY RESULTS: Two hundred eighty-three participants (75.6% men and 82.3% African-Americans) completed symptoms interviews. Over a third (34.0%) had moderate-high physical symptom burden. The most prevalent physical symptoms were joint pain, fatigue, back pain, and sleep trouble. Over half (57.6%) had psychological symptoms; 39.6% exhibited loneliness and 26.5% had high regret. In a multivariate model, being a woman (AOR 2.54, 95% CI 1.28-5.03), childhood abuse (AOR 1.88, 95% CI 1.00-3.50), cannabis use (AOR 2.59, 95% CI 1.38-4.89), multimorbidity (AOR 2.50, 95% CI 1.36-4.58), anxiety (AOR 4.30, 95% CI 2.24-8.26), hallucinations (AOR 3.77, 95% CI 1.36-10.43), and loneliness (AOR 2.32, 95% CI 1.26-4.28) were associated with moderate-high physical symptom burden. We identified four symptom clusters: minimal overall (n = 129), moderate overall (n = 68), high physical and high psychological (n = 67), and high physical and low psychological (n = 17). CONCLUSIONS: Older homeless experienced adults exhibit a high prevalence of symptoms across multiple dimensions. To reduce suffering, clinicians should recognize the interaction between symptoms and address multiple symptom dimensions. PMID- 29185176 TI - Communication Quality Predicts Psychological Well-Being and Satisfaction in Family Surrogates of Hospitalized Older Adults: An Observational Study. AB - BACKGROUND: Many hospitalized older adults require family surrogates to make decisions, but surrogates may perceive that the quality of medical decisions is low and may have poor psychological outcomes after the patient's hospitalization. OBJECTIVE: To determine the relationship between communication quality and high quality medical decisions, psychological well-being, and satisfaction for surrogates of hospitalized older adults. DESIGN: Observational study at three hospitals in a Midwest metropolitan area. PARTICIPANTS: Hospitalized older adults (65+ years) admitted to medicine and medical intensive care units who were unable to make medical decisions, and their family surrogates. Among 799 eligible dyads, 364 (45.6%) completed the study. MAIN MEASURES: Communication was assessed during hospitalization using the information and emotional support subscales of the Family Inpatient Communication Survey. Decision quality was assessed with the Decisional Conflict Scale. Outcomes assessed at baseline and 4-6 weeks post discharge included anxiety (Generalized Anxiety Disorder-7), depression (Patient Health Questionnaire-9), post-traumatic stress (Impact of Event Scale-Revised), and satisfaction (Hospital Consumer Assessment of Healthcare Providers and Systems). KEY RESULTS: The mean patient age was 81.9 years (SD 8.32); 62% were women, and 28% African American. Among surrogates, 67% were adult children. Six to eight weeks post-discharge, 22.6% of surrogates reported anxiety (11.3% moderate-severe anxiety); 29% reported depression, (14.0% moderate-severe), and 14.6% had high levels of post-traumatic stress. Emotional support was associated with lower odds of anxiety (adjusted odds ratio [AOR] = 0.65, 95% CI 0.50, 0.85) and depression (AOR = 0.80, 95% CI 0.65, 0.99) at follow-up. In multivariable linear regression, emotional support was associated with lower post-traumatic stress (beta = -0.30, p = 0.003) and higher decision quality (beta = -0.44, p < 0.0001). Information was associated with higher post-traumatic stress (beta = 0.23, p = 0.022) but also higher satisfaction (beta = 0.61, p < 0.001). CONCLUSIONS: Emotional support of hospital surrogates is consistently associated with better psychological outcomes and decision quality, suggesting an opportunity to improve decision making and well-being. PMID- 29185177 TI - An investigation of survivorship clinic attendance among childhood cancer survivors living in a five-state rural region. AB - PURPOSE: Cancer survivorship clinics manage cancer-related health complications and are available primarily in urban areas. We examine how demographic, clinical, and geographic-based characteristics are associated with attendance at the only pediatric survivorship clinic in a largely rural, multistate region. METHODS: One thousand eight hundred sixteen cancer survivors were diagnosed at age <= 25 from 1986 to 2005 while living in the region. Cox models incorporating death as a competing risk and generalized estimating equations calculated hazards ratios (HR) for characteristics measured at the clinic's opening. Subjects were followed from the clinic opening their first visit, death, emigration from the catchment area, or December 31, 2014. RESULTS: Five percent of survivors visited the clinic. Attendance is positively associated with a leukemia or lymphoma diagnosis (HR = 3.32, 95% confidence interval [CI] = 1.72-6.78 vs CNS tumors), previous relapse (HR = 1.78, 95% CI = 1.00-3.19), and residing >100 mi from the clinic (HR = 2.05, 95% CI 1.03-4.10). Survivors aged >= 31 years at clinic opening (HR = 0.19, 95% CI = 0.07-0.54) are less likely to attend than younger survivors. Residence between 16 and 100 mi had an inverse association with attendance, although not significant. CONCLUSION: Survivorship clinics are not widely attended by survivors in this catchment region. Efforts should be made to recruit survivors aged >= 31 and diagnosed with CNS tumors. Distance has a complex association with attendance, which could be attributed to the limited availability of preventative services in regions > 100 mi from the clinic. IMPLICATIONS FOR CANCER SURVIVORS: Survivors living in this catchment region may not be receiving care necessary to prevent severe late effects.

AB - Previous studies have investigated the cardiovascular activity of Gynura procumbens Merr. single-solvent extracts. The objective of this study was to evaluate the in vitro vasorelaxant properties and the underlying pharmacological mechanisms of serial extracts and fractions of Gynura procumbens (GP). The leaves of GP were serially extracted with petroleum ether, chloroform, methanol and water using the maceration method. Suspended aortic ring preparations were pre contracted with phenylephrine (PE 1 uM), followed by cumulative addition of GP extracts (0.25-3 mg/mL). The petroleum ether extract (GPPE) was the most potent among the four extracts. Pre-incubation of endothelium-intact aorta with atropine (1 uM), indomethacin (10 uM), methylene blue (10 uM), propranolol (1 uM) and potassium channel blockers such as TEA (1 uM), glibenclamide (10 uM), 4 aminopyridine (1 uM) and barium chloride (10 mM) had no effect on GPPE-induced vasorelaxation. The vasorelaxant effect of GPPE was partly diminished by pretreatment of aortic rings preparations with L-NAME (10 uM) and even more so in endothelium-denuded aortic rings, indicating a minimal involvement of endothelium dependent pathway in GPPE-induced vasorelaxation. The calcium-induced vasocontractions were antagonized significantly and concentration-dependently by GPPE in calcium free and high potassium medium. These results illustrate that Ca2+ antagonizing actions of GPPE in rat isolated aorta are comparable to that of verapamil and may be mainly responsible for its vasodilation effect. The antioxidant activity of GPPE supports its vasorelaxant effect by attenuating the production of deleterious free radicals and reactive oxygen species in the vasculature. PMID- 29185179 TI - Enniatin B and ochratoxin A in the blood serum of workers from the waste management setting. AB - The waste management occupational environment is recognized by the simultaneous presence of several substances and biologic agents. Therefore, workers are exposed simultaneously to multiple contaminants. Occupational exposure to aflatoxin B1 in one Portuguese waste sorting plant was already reported. However, besides this mycotoxin, data regarding fungal contamination showed that exposure to other mycotoxins could be expected. A study was developed to analyze if exposure to other mycotoxins besides aflatoxin B1 was occurring in the workers from the waste sorting plant previously assessed and to discuss how these findings need to be considered in the risk assessment process. In addition to aflatoxin B1 detected previously by ELISA, two additional mycotoxins and one mycotoxin degradation product were detected and quantified by a multi-mycotoxin HPLC-MS/MS approach: Enniatin B and ochratoxin A as well as 2'R-ochratoxin A. Besides the confirmation of co-exposure to several mycotoxins, results probably indicate different exposure routes for the mycotoxins reported. PMID- 29185181 TI - Efficacy and safety of transcatheter aortic valve implantation with Edwards SAPIEN 3 and XT in smaller Asian anatomy. AB - We aimed to compare the efficacy and safety of transcatheter aortic valve implantation (TAVI) using Edwards SAPIEN 3 (S3) valve and SAPIEN XT) in smaller anatomy. The new generation S3 TAVI device has been used worldwide; however, its efficacy and safety in smaller Asian anatomy remain unknown. Between February 2014 and March 2017, 166 consecutive patients (S3, 54; XT, 112) were treated with balloon-expandable TAVI in a single center and their outcomes were analyzed. Median patient age was 85 (range: 81-88) years and mean body surface area was 1.41 +/- 0.15 m2. A 23-mm size valve was used in S3 and XT groups (70 vs. 62%, p = 0.224). The transfemoral approach was more frequently used in the S3 than in the XT group (96 vs. 72%, p < 0.001). Although, the minimal luminal diameter of the femoral artery was smaller in the S3 group (5.9 vs. 6.4 mm, p = 0.001), the rates of major (2 vs. 11%, p = 0.226) and minor (11 vs. 5%, p = 0.107) vascular complications did not increase. The frequency of paravalvular leaks (PVL) >= 2 was significantly reduced in the S3 group (11 vs. 61%, p < 0.001); however, pre- (24 vs. 91%, p < 0.001) and post- (4 vs. 19%, p < 0.001) dilatations were less frequently performed. Pacemaker implantation incidence did not increase (4 vs. 5%, p = 1.0) and peak velocity of the transcatheter heart valve was significantly higher in the S3 group (2.3 vs. 2.2 m/s, p = 0.046). Device success was high (89 vs. 93%, p = 0.387) while the 30-day all-cause mortality was low (2 vs. 1%, p = 0.583) in both groups. TAVI with the S3 device was safe and effective, with low incidence of vascular complications and reduced PVL, in smaller body-sized Asians. PMID- 29185180 TI - Subtype Specification of Cerebral Cortical Neurons in Their Immature Stages. AB - The diversification of neuronal subtypes during corticogenesis is fundamental to the establishment of the complex cortical structure. Although subtype specification has been assumed to occur in neural progenitor cells, increasing evidence has begun to reveal the plasticity of subtype determination in immature neurons. Here, we summarize recent findings regarding the regulation of subtype specification during later periods of neuronal differentiation, such as the post mitotic and post-migratory stages. We also discuss thalamocortical axons as an extra-cortical cue that provides information on the subtype determination of immature cortical neurons.

AB - PURPOSE: Acoustic trauma is more prevalent in military settings, especially among individuals with combat-related military occupational specialties. Gunfire, improvised explosive devices, and mortar explosions are a few examples that may cause hearing degradation and tinnitus. It is possible that the same events that are associated with auditory problems can cause traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD). METHOD: This paper reviews the distinct and overlapping symptoms of tinnitus, TBI, and PTSD, and how these disorders interact to synergistically promote negative outcomes. RESULTS: Tinnitus may serve as a significant contributor to symptoms of TBI and PTSD. Therefore, tinnitus subtypes could be identified as physiologically or psychologically based, or both. CONCLUSIONS: Additional research is warranted to determine the common and unique symptoms and associated neurological pathways of tinnitus, TBI, and PTSD. Brief treatment recommendations are provided, including a multidisciplinary approach for the physical and psychological distress associated with tinnitus. PMID- 29185184 TI - Changes in contractile and metabolic parameters of skeletal muscle as rats age from 3 to 12 months. AB - Laboratory rats are considered mature at 3 months despite that musculoskeletal growth is still occurring. Changes in muscle physiological and biochemical characteristics during development from 3 months, however, are not well understood. Whole muscles and single skinned fibres from fast-twitch extensor digitorum longus (EDL) and predominantly slow-twitch soleus (SOL) muscles were examined from male Sprague-Dawley rats (3, 6, 9, 12 months). Ca2+ sensitivity of contractile apparatus decreased with age in both fast- (~ 0.04 pCa units) and slow-twitch (~ 0.07 pCa units) muscle fibres, and specific force increased (by ~ 50% and ~ 25%, respectively). Myosin heavy chain composition of EDL and SOL muscles altered to a small extent with age (decrease in MHCIIa proportion after 3 months). Glycogen content increased with age (~ 80% in EDL and 25% in SOL) and GLUT4 protein density decreased (~ 35 and 20%, respectively), whereas the glycogen-related enzymes were little changed. GAPDH protein content was relatively constant in both muscle types, but COXIV protein decreased ~ 40% in SOL muscle. Calsequestrin (CSQ) and SERCA densities remained relatively constant with age, whereas there was a progressive ~ 2-3 fold increase in CSQ-like proteins, though their role and importance remain unclear. There was also ~ 40% decrease in the density of the Na+, K+-ATPase (NKA) alpha1 subunit in EDL and the alpha2 subunit in SOL. These findings emphasise there are substantial changes in skeletal muscle function and the density of key proteins during early to mid adulthood in rats, which need to be considered in the design and interpretation of experiments. PMID- 29185185 TI - The Long-Term Effects of the Adjustable Gastric Band on Esophageal Motility in Patients Who Present for Band Removal. AB - BACKGROUND: During the past decade, laparoscopic adjustable gastric banding (LAGB) was one of the most popular surgical procedures in treating morbid obesity. Long-term effects, specifically on esophageal motility, of LAGB have not been well described in the literature despite the high prevalence of reoperations and post-operative dysphagia. We aimed to characterize esophageal dysmotility after long-term follow-up using data of high-resolution esophageal manometry (HRM) performed in patients who presented for LAGB removal. The research was conducted in Academic Hospital Center in the USA. METHODS: Research was conducted with approval from the institution's Institutional Review Board. We included 25 consecutive patients who were requesting removal of the band or revisional bariatric surgery. All patients underwent HRM between 2011 and 2015. RESULTS: A Fisher's exact test two-sided p value 0.41 shows no statistically significant difference in proportions of normal motility or impaired motility between asymptomatic and symptomatic patients. CONCLUSIONS: Patients with a history of LABG can have esophageal dysmotility whether they are symptomatic or asymptomatic. Based on existing literature, we recommend pre-operative manometry in these patients requesting revisional surgery.

AB - Various azo compounds (Modified dyes) have been synthesised by chemical modification of areca nut extract (epicatechin), a plant-based Polyphenolic compound to get semi-synthetic dyes. Three different primary amines namely p- nitro aniline, p-anisidine and aniline, were diazotized to form their corresponding diazonium salts which were further coupled with an areca nut extract. Preliminary characterization of the areca nut extract and the resultant azo compounds (Modified dyes) was carried out in terms of melting point, solubility tests, thin layer chromatography, UV-Visible and FTIR spectroscopy. These modified dyes were further applied on polyester and nylon fabrics and % dye exhaustion was evaluated. Dyed fabrics were further tested for their fastness properties such as wash fastness, rubbing fastness, light fastness and sublimation fastness. The results of the fastness tests indicate that, all the three modified dyes have good dyeability for polyester and nylon fabrics. The dyed fabrics were also tested for ultraviolet protection factor which showed very good ultraviolet protection. PMID- 29185187 TI - Extracellular Vesicle Biology in Alzheimer's Disease and Related Tauopathy. AB - Extracellular vesicles (EVs) are physiological vesicles secreted from most eukaryotes and contain cargos of their cell of origin. EVs, and particularly a subset of EV known as exosomes, are emerging as key mediators of cell to cell communication and waste management for cells both during normal organismal function and in disease. In this review, we investigate the rapidly growing field of exosome biology, their biogenesis, cargo loading, and uptake by other cells. We particularly consider the role of exosomes in Alzheimer's disease, both as a pathogenic agent and as a disease biomarker. We also explore the emerging role of exosomes in chronic traumatic encephalopathy. Finally, we highlight open questions in these fields and the possible use of exosomes as therapeutic targets and agents.

AB - MicroRNAs (miRs) are potential therapeutic targets in glioblastoma multiforme (GBM), but the difficulties associated with their delivery to tumor target cells have hampered their widespread use. Mesenchymal stem cells (MSCs) can migrate to the sites of cancers, including GBM and exert anti-tumor effects. In this study, it is shown that Wharton's jelly-MSCs (WJ-MSCs) have the ability to deliver exogenous miRs to GBM cells and the functional impact of this delivery is characterized. It is found that the labeled miR-124, as an example for miR of interest, can be successfully delivered with WJ-MSCs to U87 GBM cells via dependent or exosome-independent processes. It is demonstrated that the delivered exogenous miR-124 significantly decreases the luciferase activity of the target gene CDK6. In addition, the delivered miR-124 enhances the chemosensitivity of GBM cells to temozolomide and decreases the migration of GBM cells. These results suggest that the use of exogenous miRNA delivery with the derived exosomes from WJ-MSCs may provide a novel approach for miRNA replacement therapy in GBM cancers. PMID- 29185192 TI - A Functional Aryl Hydrocarbon Receptor Genetic Variant, Alone and in Combination with Parental Exposure, is a Risk Factor for Congenital Heart Disease. AB - Recent experimental studies showed that ablation of the aryl hydrocarbon receptor (AhR) as well as its activation by exogenous ligands disrupt the molecular networks involved in heart formation and function, leading to congenital heart disease (CHD). However, no evidence is available about the role of AhR in humans. We assessed the prevalence of a functional AhR genetic variant (p.Arg554Lys) in CHD patients as well as its joint effects with parental exposure. A total of 128 CHD patients (76 males; age 6.2 +/- 6.7 years) and 274 controls (160 males; age at birth) were genotyped for the AhR polymorphism by using the TaqMan(r) Drug Metabolism Genotyping assay. Both case and control parents completed a structured questionnaire on demographic, lifestyle and preconception exposures. Genotype (p = 0.001) and allele (p < 0.0001) distributions of AhR p.Arg554Lys differed significantly between patients and controls. A significant elevated CHD risk was found under dominant (OR = 2.9, 95% CI 1.9-4.6, p < 0.0001) and additive genetic models (OR = 6.2, 95% CI 2-19, p = 0.001). There was a significant interaction between 554-Lys allele and paternal smoking exposure (ORsmoking = 1.6, 95% CI = 0.9-2.9; ORallele = 2.6, 95% CI = 1.3-5; ORinteraction = 4.9, 95% CI = 2.4-9.9, p interaction < 0.0001). Additionally, 554-Lys allele exacerbated the effect of maternal periconceptional exposure (ORexposure = 1.6, 95% CI = 0.8-3; ORallele = 2.6, 95% CI = 1.5-4.5; ORinteraction = 5.7; 95% CI = 2.6-12, p interaction < 0.0001). Our findings showed that the AhR p.Arg554Lys polymorphism, alone and in combination with parental exposures, is associated with the CHD risk, highlighting the significant role of AhR in the cardiovascular development. PMID- 29185193 TI - Physical exercise promotes memory capability by enhancing hippocampal mitochondrial functions and inhibiting apoptosis in obesity-induced insulin resistance by high fat diet. AB - A high-fat diet induces obesity in mice, leading to insulin resistance, decreased mitochondrial function, and increased apoptosis in the hippocampus, which eventually result in memory loss. The present study investigated the effect of physical exercise on memory, hippocampal mitochondrial function, and apoptosis in mice with in insulin resistance caused by obesity due to high-fat diet. Mice were randomly divided into four groups: control (CON), control and exercise (CON + EX), high fat diet (HFD), and high fat diet and exercise (HFD + EX). After receiving a high-fat (60%) diet for 20 weeks to induce obesity, the animals were subjected to an exercise routine 6 times per week, for 12 weeks. The exercise duration and intensity gradually increased over 4-week intervals. Hippocampal memory was examined using the step-down avoidance task. Mitochondrial function and apoptosis were also examined in the hippocampus and dentate gyrus. We found that obesity owing to a high-fat diet induced insulin resistance and caused a decrease in memory function. Insulin resistance also caused a decrease in mitochondrial function in the hippocampus by reducing Ca2+ retention and O2, respiration, increasing the levels of H2O2, and Cyp-D, and mPTP opening. In addition, apoptosis in the hippocampus increased owing to decreased expression of Bcl-2 and increased expression of Bax, cytochrome c, and caspase-3 and TUNEL positive cells. In contrast, physical exercise led to reduced insulin resistance, improved mitochondrial function, and reduced apoptosis in the hippocampus. The results suggest that physiological stimulations such as exercise improve hippocampal function and suppress apoptosis, potentially preventing the memory loss associated with obesity-induced insulin resistance.

PMID- 29185197 TI - A Non-Peptidic S100A9 Specific Ligand for Optical Imaging of Phagocyte Activity In Vivo. AB - PURPOSE: Non-invasive assessment of inflammatory activity in the course of various diseases is a largely unmet clinical challenge. An early feature of inflammation is local secretion of the alarmin S100A8/A9 by activated phagocytes. We here evaluate a novel S100A9-targeted small molecule tracer Cy5.5-CES271 for in vivo optical imaging of inflammatory activity in exemplary disease models. PROCEDURES: Dynamics of Cy5.5-CES271 was characterized in a model of irritant contact dermatitis by sequential fluorescence reflectance imaging (FRI) up to 24 h postinjection (p.i.). Specificity of Cy5.5-CES271 binding to S100A9 in vivo was examined by blocking studies and by employing S100A9-/- mice. Finally, S100A9 secretion in acute lung inflammation was assessed by Cy5.5-CES271 and FRI of explanted lungs. RESULTS: In ear inflammation, we were able to non-invasively follow the time course of S100A9 expression using Cy5.5-CES271 and FRI over 24 h p.i. (peak activity at 3 h p.i.). Specificity of imaging could be shown by a significant signal reduction after predosing and using S100A9-/- mice. In acute lung injury, local and systemic S100A8/A9 levels increased over time and correlated significantly with FRI signal levels in explanted lungs. CONCLUSIONS: Cy5.5-CES271 shows significant accumulation in models of inflammatory diseases and specific binding to S100A9 in vivo. This study, for the first time, demonstrates the potential of a small molecule non-peptidic tracer enabling imaging of S100A9 as a marker of local phagocyte activity in inflammatory scenarios suggesting this compound class for translational attempts. PMID- 29185198 TI - Metastatic renal cell carcinoma to the small bowel: three cases of GI bleeding and a literature review. AB - Approximately 25-30% of patients with renal cell carcinoma (RCC) have metastatic disease at the time of diagnosis, where the most common sites of metastasis are the lung (50-60% of patients with metastatic disease), bones (30-40%), liver (30 40%), and brain (5%). Although RCC metastasis to the small intestine is thought to be exceedingly rare, with predominantly isolated case reports and a few case series in the literature, we present below three additional cases at our institution of metastatic RCC to the small bowel presenting as GI bleeding. A literature review demonstrates that the number of published case reports has been increasing in recent years. We hypothesize that in the era of targeted chemotherapy and VEGF inhibitors to treat RCC that patients are living longer and have more time for their primary tumors to metastasize to the small bowel and become symptomatic, causing metastatic RCC to the small bowel to be less rare than previously thought.

AB - INTRODUCTION: Predictors for the effect of sodium glucose co-transporter 2 (SGLT2) inhibitors at lowering hemoglobin A1c (HbA1c) levels in type 2 diabetes mellitus patients remain unclear. We therefore aimed to elucidate these predictors in type 2 diabetes patients after 3 months of SGLT2 treatment. METHODS: A total of 302 consecutive type 2 diabetes patients who had been treated with SGLT2 inhibitors as monotherapy or add-on therapy to existing antidiabetic treatments were enrolled retrospectively. After excluding 27 patients whose HbA1c levels could not be evaluated 3 months after treatment, the glucose-lowering effects of SGLT2 inhibitors were assessed in 275 patients by measuring HbA1c levels before and 3 months after treatment. The predictors for changes in HbA1c levels after 3 months of treatment were evaluated. RESULTS: SGLT2 inhibitor treatment for 3 months decreased HbA1c levels from 7.8 +/- 1.2% to 7.4 +/- 1.0% (p < 0.0001). A multiple regression analysis showed that the independent determinants for SGLT2 inhibitor treatment effect included decreased HbA1c levels after 1 month of treatment, high baseline HbA1c levels, and a high estimated glomerular filtration rate (eGFR). CONCLUSION: We show that type 2 diabetes patients who received the greatest glucose-lowering effect with SGLT2 inhibitor treatment were those with preserved renal function (high baseline eGFR) and high baseline HbA1c levels. Moreover, SGLT2 inhibitor treatment efficacy could be predicted by the patients' initial response to treatment. PMID- 29185200 TI - The MTHFR polymorphism affect the susceptibility of HCC and the prognosis of HCC liver transplantation. AB - BACKGROUND: Methylenetetrahyfrofolate reductase (MTHFR) is the key enzyme for one carbon and folate metabolism. Previous studies have drawn different conclusions about the relationship between the mutation of MTHFR and hepatocellular carcinoma (HCC) occurrence. MTHFR polymorphisms' influence on liver transplantation for HCC recurrence has yet not been reported. Aim of this study was to clarify the impact of MTHFR polymorphism on hepatocarcinogenesis and the prognosis of liver transplant recipient with HCC. METHODS: This study enrolled 244 HCC patients and 487 healthy individuals in Chinese Han population to analyze the influence of MTHFR polymorphism on HCC susceptibility first. Furthermore, this research choose another 100 donors' and 104 recipients' specimens to detect the association between polymorphism of MTHFR and post-transplant HCC recurrence. RESULT: rs1801131 polymorphism A to C was associated with the occurrence of HCC in Chinese Han population (p < 0.05), especially in age exceeding 50 years (p < 0.01). No association was observed with rs1801133 polymorphism and HCC occurrence. The mean tumor-free survival for recipients with donor liver graft rs1801133 C to T variants was shorter than CC type (12.63 +/- 3.84 vs 22.43 +/- 4.74 months, p < 0.05). Multivariate analysis revealed that Donor rs1801133 and Hangzhou criteria were two independent prognostic factors for tumor-free survival (p < 0.05). Neither donor rs1801131 polymorphism nor recipients' MTHFR polymorphisms was associated with HCC recurrence. CONCLUSION: This study demonstrated that MTHFR polymorphism was associated with HCC occurrence and post transplant HCC recurrence. rs1801131 mutation A to C is a valuable molecular biomarker for predicting HCC occurrence in Chinese Han population. Donor MTHFR rs1801133 C to T polymorphism could present as a promising prognostic biomarkers for HCC recurrence in liver transplant recipients. PMID- 29185201 TI - Are training and transfer effects of working memory updating training modulated by achievement motivation? AB - Previous studies examining effects of working memory (WM) updating training revealed mixed results. One factor that might modulate training gains, and possibly also transfer of those gains to non-trained cognitive tasks, is achievement motivation. In the present Studies 1 and 2, students with either a high (HAM) or low (LAM) achievement motivation completed a 14-day visuospatial WM updating training program. In Study 2, the students also performed a set of tasks measuring other executive functions and fluid intelligence prior to and after training. In both studies, the HAM students displayed a larger training gain than the LAM students. Study 2 revealed that after training, both groups showed better performance on the near-transfer but not far-transfer tasks. Importantly, the differential training gain was not associated with better post-training performance for the HAM compared to the LAM students on any of the transfer tasks. These results are taken to support a modulatory role of achievement motivation on WM training benefits, but not on transfer of those benefits to other tasks. Possible reasons for the general improvement on the near-transfer tasks and the absence of a modulatory role of achievement motivation on transfer task performance are discussed. PMID- 29185202 TI - Tumor-infiltrating lymphocytes affect the efficacy of trastuzumab-based treatment in human epidermal growth factor receptor 2-positive breast cancer. AB - BACKGROUND: Immune responses play an important role in interrupting the progression of cancer cells. Tumor-infiltrating lymphocytes (TILs) are basic components of the immune system. In triple negative breast cancer, increased number of TILs is associated with excellent prognosis and response of chemotherapy. Here, we investigated whether TILs affect the efficacy of trastuzumab-based treatment in human epidermal growth factor receptor 2 (HER2) positive breast cancer. METHODS: The study included 97 patients with stage I-III HER2-positive breast cancer. All patients were preoperatively treated with an anthracycline-based combination regimen, followed by taxane with trastuzumab from 2009 to 2013. Pathological complete response (pCR) was defined as the disappearance of invasive cancer cells regardless of the presence of in situ components. TILs were evaluated using pre-therapeutic needle biopsy specimens. We assessed the percentage of the breast stroma with TILs over the total intratumoral stroma and classified the specimens in three grades: TILs1+ < 30%, TILs2+ 30-50%, and TILs3+ > 50%. RESULTS: Overall, 80.4% of the specimens were TILs1+, 15.5% were TILs2+ and 4.1% were TILs3+. The pCR rate was 44.9% (35/78) in the TILs1+ cases, 80.0% (12/15) in the TILs2+ cases and 75.0% (3/4) in the TILs3+ cases. TILs were significantly associated with pCR (P = 0.0228). Multivariate analysis using TILs, hormone receptor (HR), nuclear grade (NG) and age indicated that TILs (OR 4.32, 95% CI 1.04-23.33, P = 0.0436) and HR (OR 8.76, 95% CI 3.30 25.44, P < 0.0001) were independent predictors for pCR. CONCLUSION: TILs are associated with the efficacy of trastuzumab-based treatment in HER2-positive breast cancer. PMID- 29185203 TI - Genetic Diversity Among Genogroup II Noroviruses and Progressive Emergence of GII.17 in Wastewaters in Italy (2011-2016) Revealed by Next-Generation and Sanger Sequencing. AB - Noroviruses (NoV) are a major cause of gastroenteritis worldwide. Recently, a novel variant of NoV GII.17 (GII.P17_GII.17 NoV), termed Kawasaki 2014, has been increasingly reported in NoV outbreaks in Asia, and has also been described in Europe and North America. In this study, sewage samples were investigated to study the occurrence and genetic diversity of NoV genogroup II (GII) along a 6 year period. Moreover, the spread of GII.17 strains (first appearance and occurrence along time) was specifically assessed. A total of 122 sewage samples collected from 2011 to 2016 from four wastewater treatment plants in Rome (Italy) were initially tested using real-time RT-(q)PCR for GII NoV. Positive samples were subsequently subjected to genotypic characterization by RT-nested PCRs using broad-range primes targeting the region C of the capsid gene of GII NoV, and specific primers targeting the same region of GII.17 NoV. In total, eight different genotypes were detected with the broad-range assay: GII.1 (n = 6), GII.2 (n = 8), GII.3 (n = 3), GII.4 (n = 13), GII.6 (n = 3), GII.7 (n = 2), GII.13 (n = 2), and GII.17 (n = 3), with the latter two genotypes detected only in 2016. Specific amplification of GII.17 NoV was successful in 14 out of 110 positive samples, spanned over the years 2013-2016. The amplicons of the broad range PCR, pooled per year, were further analyzed by next-generation sequencing (NGS) for a deeper analysis of the genotypes circulating in the study period. NGS confirmed the circulation of GII.17 NoV since 2013 and detected, beyond the eight genotypes identified by Sanger sequencing, three additional genotypes regarded as globally uncommon: GII.5, GII.16, and GII.21. This study provides evidence that GII.17 NoV Kawasaki has been circulating in the Italian population before its appearance and identification in clinical cases, and has become a major genotype in 2016. Our results confirm the usefulness of wastewater surveillance coupled with NGS to study the molecular epidemiology of NoV and to monitor the emergence of NoV strains. PMID- 29185204 TI - Impact of chronic obstructive pulmonary disease and frailty on long-term outcomes and quality of life after transcatheter aortic valve implantation. AB - BACKGROUND: Association between chronic obstructive pulmonary disease (COPD) and long-term mortality as well as the quality of life (QoL) in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) is still unclear. AIM: We sought to evaluate the impact of COPD on mortality and QoL of patients with AS undergoing TAVI. METHODS: A total of 148 consecutive patients who underwent TAVI were enrolled and stratified by history of COPD. RESULTS: Of 148 patients enrolled, 19 (12.8%) patients had a history of COPD. Patients with COPD were high-risk patients with higher prevalence of incomplete revascularization and frailty features. At follow-up of 15.8 months, all-cause mortality in patients with COPD was over four times higher than in patients without COPD [17.8% vs. 52.6%; p = 0.002-age/gender-adjusted OR (95% CI) 4.73 (1.69-13.24)]. On the other hand, in Cox regression model, the only independent predictors of all-cause death at long-term follow-up were: incomplete coronary revascularization [HR (95% CI) 5.45 (2.38-12.52); p = 0.001], estimated glomerular filtration rate [per 1 ml/min/1.73 m2 increase: 0.96 (0.94-0.98); p = 0.001], and previous stroke/transient ischemic attack [2.86 (1.17-7.00); p = 0.021]. Also, the difference in mortality between patients with and without COPD was not significant after adjustment for the most of frailty indices. Importantly, groups were comparable in terms of QoL at baseline and 12 months. CONCLUSION: COPD may pose an important factor affecting long-term outcomes of patients with severe AS undergoing TAVI. However, its effects might be partially related to coexisting comorbidities and frailty. PMID- 29185205 TI - I and Us: A Longitudinal Study on the Interplay of Personal and Social Identity in Adolescence. AB - The development of personal and social identity is crucial in adolescence. On the one hand, adolescents face the task of forming and consolidating their personal identity in multiple domains, with educational and interpersonal domains particularly salient. On the other hand, they enlarge their social horizon and increasingly define themselves as members of multiple peer groups, such as groups of classmates and friends met outside school. There is however a lack of integrative research on the interplay among and between personal and social identity processes. Hence the purpose of this study was threefold. First, we examined how personal identity processes in the educational and interpersonal domains are associated longitudinally. Second, we investigated to what extent social identifications with classmates and with the group of friends are associated over time. Third, with an original approach we examined the longitudinal interplay between personal and social identity processes, to connect theoretical contributions that have so far proceeded largely in parallel. Participants were 304 adolescents (61.84% female, M age = 17.49) involved in a three-wave longitudinal study. We found that (a) the ways in which adolescents develop their identity in the educational and interpersonal domains become more closely intertwined over time; (b) identifications with classmates and with the group of friends are interconnected; and (c) personal and social identity processes are associated both concurrently and longitudinally, with most cross lagged effects showing that social identifications influence personal identity formation and consolidation in the interpersonal identity domain. Theoretical implications are discussed. PMID- 29185206 TI - Reciprocal Associations between Educational Identity and Vocational Identity in Adolescence: A Three-wave Longitudinal Investigation. AB - Education and vocation are core identity domains in adolescence. School is a normative social context in this developmental time frame and the formation of an educational identity is embedded in the goals that youth pursue in school. One of the main goals of education is to prepare young people for their future careers. Hence, educational identity should support the formation of vocational identity during adolescence. Considering the limited evidence on the longitudinal links between these two domain-specific identities, we conducted a three-wave investigation, testing the moderating role of age group, gender, and type of school. Participants (N = 1030; 59.3% female) were adolescents (M age = 16.72 years, SD age = 1.23, age range 14-19 years) who completed self-report measures of educational and vocational identity three times during an academic year. We underscored reciprocal associations between educational identity and vocational identity. The results indicate that strong educational commitments supported the formation of strong vocational commitments across time. Adolescents who were involved in the in-depth exploration of their educational choices also reported more vocational exploration during the school year. In turn, vocational identity processes also supported educational identity formation, especially the reconsideration of educational commitments. In terms of moderators, we underscored that vocational commitment making and vocational flexibility bolstered educational commitment only in early-to-middle adolescents. Educational in-depth exploration fostered the identification with vocational commitments only in girls. Educational reconsideration of commitment promoted vocational self doubt only in adolescents attending work-bound high-schools. Implications for research and practice are discussed. PMID- 29185207 TI - Prosocial Behavior in Adolescence: Gender Differences in Development and Links with Empathy. AB - Although adolescents' prosocial behavior is related to various positive outcomes, longitudinal research on its development and predictors is still sparse. This 6 wave longitudinal study investigated the development of prosocial behavior across adolescence, and examined longitudinal associations with perspective taking and empathic concern. Participants were 497 adolescents (M age t1 = 13.03 years, 43% girls) who reported on their prosocial behaviors, empathic concern, and perspective taking. The results revealed marked gender differences in the development of prosocial behavior. For boys, levels of prosocial behavior were stable until age 14, followed by an increase until age 17, and a slight decrease thereafter. For girls, prosocial behavior increased until age 16 years and then slightly decreased. Regarding longitudinal associations, empathic concern was consistently related to subsequent prosocial behavior. However, perspective taking was only indirectly related to prosocial behavior, via its effect on empathic concern. Tests of the direction of effects showed support for the notion that earlier prosocial behavior predicts subsequent empathy-related traits, but only for girls. The findings support cognitive-developmental and moral socialization theories of prosocial development and the primary role of moral emotions in predicting prosocial behaviors. Our findings inform strategies to foster prosocial behaviors by emphasizing moral emotions rather than moral cognitions during adolescence. PMID- 29185209 TI - Value of the Oxford classification of IgA nephropathy in children with Henoch Schonlein purpura nephritis. AB - BACKGROUND: The widely used International Study of Kidney Disease in Children (ISKDC) classification for Henoch-Schonlein purpura nephritis (HSPN) does not completely correlate with the clinical presentation and long-term prognosis of this disease. Primary IgA nephropathy (IgAN) and HSPN share common features; thus, the Oxford classification of IgAN might be useful in predicting the long term outcomes of HSPN. However, its value has not been confirmed in children with HSPN. METHODS: We selected children with HSPN diagnosed between 2003 and 2015, and reclassified their renal biopsies according to the Oxford classification scoring system. The primary outcome was impaired renal function, and remission of proteinuria and clinical remission were secondary outcomes. RESULTS: We included 104 patients (58 males, 46 females) with a median age of 10 (4-17) years. Mesangial hypercellularity (M1) was strongly associated with proteinuria, and tubular atrophy/interstitial fibrosis (T1&2) and C2 (with crescents in > 25% of glomeruli) were associated with reduced estimated glomerular filtration rate (eGFR) at the time of biopsy. Patients with M1, endocapillary proliferation (E1), segmental glomerulosclerosis (S1), and crescents (C1&2) were more likely to have been treated with high-dose methylprednisolone. At univariate time-dependent analyses, S1 was strongly associated with the primary outcome (p = 0.025), whereas T1&2 was significantly negatively associated with proteinuria remission (p = 0.035) and clinical remission (p = 0.038). CONCLUSIONS: Our findings suggest that the Oxford classification is valid for children with HSPN. S and T lesions, which are ignored in the ISKDC classification, can be used to assess renal outcomes of HSPN, and such assessments are not affected by currently available treatments. The value of M, E and C lesions in predicting response to therapy and renal outcome warrants further study. PMID- 29185208 TI - Neighborhood or School? Influences on Alcohol Consumption and Heavy Episodic Drinking Among Urban Adolescents. AB - Little is known about the relative influences of neighborhood and school on the alcohol socialization process. Survey data from the Young in Oslo Study (N = 10,038, mean age 17.1 years, 52% girls) were used to investigate the details of such influences, using cross-classified multilevel models. School and neighborhood contexts were equally important for ordinary alcohol use; however, neighborhood influences were mainly explained by individual and family factors, whereas peer-based sociocultural processes played a key role in explaining school effects. Neither context had much impact on heavy episodic drinking. The study suggests that "privileged" youth may be at risk of high alcohol consumption. Parental influences and peer-based sociocultural aspects of the school milieu should be considered in prevention efforts. PMID- 29185210 TI - Acute kidney injury based on the KDIGO criteria among ST elevation myocardial infarction patients treated by primary percutaneous intervention. AB - BACKGROUND: Acute kidney injury (AKI) following acute ST elevation myocardial infarction (STEMI) is associated with adverse outcomes. The recently proposed KDIGO criteria suggested modifications to the consensus classification system for AKI, namely lowering the threshold of increase in absolute serum creatinine and extending the time frame for AKI detection to 7 days. We evaluated the incidence, risk factors, and long-term mortality associated with AKI as classified by the KDIGO definition in a large single center cohort of consecutive STEMI patients. METHODS: We retrospectively studied 2122 consecutive STEMI patients undergoing primary percutaneous coronary intervention (PCI). Recruited patients were admitted between January 2008 and May 2016 to the cardiac intensive care unit with the diagnosis of acute STEMI. We compared the utilization of the KDIGO and consensus criteria for the diagnosis of AKI and its relation to long term mortality. RESULTS: The KDIGO criteria allowed the identification of more patients as having AKI (10.6 vs. 5.6%, p < 0.001) compared to the consensus criteria. Even mild elevation of serum creatinine (>= 0.3 mg/dL) was associated with a marked increase in all-cause mortality (HR 4.7, 95% CI 3.1-6.43, p < 0.001). Patients with AKI whose renal function resolved prior to hospital discharge still had significantly higher mortality compared to patients with no AKI (23 vs. 8%, HR 3.1, 95% CI 2.09-4.90, p < 0.001). CONCLUSION: KDIGO criteria is more sensitive than the consensus criteria in defining AKI in STEMI patients and identifying populations at risk for long term adverse outcomes. PMID- 29185211 TI - Plasma EBV microRNAs in paediatric renal transplant recipients. AB - BACKGROUND: Epstein-Barr virus (EBV) was the first human virus identified to express microRNA (miRNA). To date, 44 mature miRNAs are encoded for within the EBV genome. EBV miRNAs have not been profiled in paediatric renal transplant recipients. In this study, we investigated circulating EBV miRNA profiles as novel biomarkers in paediatric renal transplant patients. METHODS: Forty-two microRNAs encoded within 2 EBV open reading frames (BART and BHRF) were examined in renal transplant recipients who resolved EBV infection (REI) or maintained chronic high viral loads (CHL), and in non-transplant patients with acute infectious mononucleosis (IM). RESULTS: Plasma EBV-miR-BART2-5p was present in higher numbers of IM (7/8) and CHL (7/10) compared to REI (7/12) patients. A trend was observed between the numbers of plasma EBV miRNAs expressed and EBV viral load (p < 0.07). Several EBV-miRs including BART7-3p, 15, 9-3p, 11-3p, 1-3p and 3-3p were detected in IM and CHL patients only. The lytic EBV-miRs, BHRF1-2 3p and 1-1, indicating active viral replication, were detected in IM patients only. One CHL patient developed post-transplant lymphoproliferative disease (PTLD) after several years and analysis of 10 samples over a 30-month period showed an average 24-fold higher change in plasma EBV-miR-BART2-5p compared to the CHL group and 110-fold higher change compared to the REI group. CONCLUSIONS: Our results suggest that EBV-miR-BART2-5p, which targets the stress-induced immune ligand MICB to escape recognition and elimination by NK cells, may have a role in sustaining high EBV viral loads in CHL paediatric kidney transplant recipients. PMID- 29185212 TI - A semiparametric additive rate model for a modulated renewal process. AB - Recurrent event data from a long single realization are widely encountered in point process applications. Modeling and analyzing such data are different from those for independent and identical short sequences, and the development of statistical methods requires careful consideration of the underlying dependence structure of the long single sequence. In this paper, we propose a semiparametric additive rate model for a modulated renewal process, and develop an estimating equation approach for the model parameters. The asymptotic properties of the resulting estimators are established by applying the limit theory for stationary mixing sequences. A block-based bootstrap procedure is presented for the variance estimation. Simulation studies are conducted to assess the finite-sample performance of the proposed estimators. An application to a data set from a cardiovascular mortality study is provided. PMID- 29185213 TI - Carotid artery ligation induced intimal thickening and proliferation is unaffected by ageing. AB - Following interventions to treat atherosclerosis, such as coronary artery bypass graft surgery, restenosis occurs in approximately 40% of patients. Identification of proteins regulating intimal thickening could represent targets to prevent restenosis. Our group previously demonstrated that in a murine model of vascular occlusion, Wnt4 protein expression and beta-catenin signalling was upregulated which promoted vascular smooth muscle cell (VSMC) proliferation and intimal thickening. In this study, the effect of age on VSMC proliferation, intimal hyperplasia and Wnt4 expression was investigated. In vitro proliferation of VSMCs isolated from young (2 month) or old (18-20 month) C57BL6/J mice was assessed by immunocytochemistry for EdU incorporation. As previously reported, 400 ng/mL recombinant Wnt4 protein increased proliferation of VSMCs from young mice. However, this response was absent in VSMCs from old mice. As our group previously reported reduced intimal hyperplasia in Wnt4+/- mice compared to wildtype controls, we hypothesised that impaired Wnt4 signalling with age may result in reduced neointimal formation. To investigate this, carotid artery ligation was performed in young and old mice and neointimal area was assessed 21 days later. Surprisingly, neointimal area and percentage lumen occlusion were not significantly affected by age. Furthermore, neointimal cell density and proliferation were also unchanged. These data suggest that although Wnt4-mediated proliferation was impaired with age in primary VSMCs, carotid artery ligation induced neointimal formation and proliferation were unchanged in old mice. These results imply that Wnt4-mediated proliferation is unaffected by age in vivo, suggesting that therapeutic Wnt4 inhibition could inhibit restenosis in patients of all ages. PMID- 29185214 TI - The significance of preexisting medical conditions, alcohol/drug use and suicidal behavior for drivers in fatal motor vehicle crashes: a retrospective autopsy study. AB - Driver fatalities in motor vehicle collisions (MVCs) encompass accidents, suicides, and natural deaths when driving. The objective of this study was to determine the significance of pathology and other autopsy findings for drivers in fatal MVCs. Forensic autopsy records of driver fatalities in southeast Norway between 2000 and 2014 were studied retrospectively. Data from individual police and collision investigation reports were also collected and analyzed. In 406 driver fatalities, the male/female ratio was 340/66; 9% died from natural causes, 9% were suicides, 65% were culpable accidental deaths, 14% were nonculpable deaths, and 3% were undetermined deaths. Head injuries and thoracic injuries were the most common causes of death. A seatbelt had been worn in 50% of the fatalities, and its prevalence did not differ between accidental deaths and suicides. Blood levels of alcohol and/or drugs that indicated impairment at the time of the collision were found in 40% (105/262) of all culpable accidental deaths but in 50% (64/127) of drivers aged up to 35 years. Pathology (most often cardiovascular disease) suggestive of sudden incapacitation before the collision was present in 24% (62/264) of drivers who were culpable in the accident and in 70% (46/66) of culpable drivers older than 55 years. A substantial proportion of drivers are killed in accidental collisions that may have occurred as a result of either alcohol/drug impairment or preexisting disease. Suicides and natural deaths both constitute significant proportions of MVC fatalities and may be misclassified unless a full inquest including an autopsy is performed. PMID- 29185215 TI - Nickle(II) ions exacerbate bleomycin-induced pulmonary inflammation and fibrosis by activating the ROS/Akt signaling pathway. AB - Nickle (Ni) is a heavy metal found in particulate matter. We previously reported that Ni ions are strongly associated with high apoptosis rates and high expression of IL-1beta in human bronchial epithelial cells following exposure to PM2.5; however, the effects of Ni ions on pulmonary fibrosis have not been fully elucidated. In the current study, we evaluated whether Ni ions can exacerbate bleomycin (BLM)-induced pulmonary fibrosis in a mouse model and illustrated the potential mechanism. Ni ions inhibited cell proliferation and induced apoptosis in A549 and MRC-5 cells. BLM-induced lung injury and fibrosis in mice were significantly enhanced by nickel treatment, and these findings were also supported by inflammatory cell accumulation in bronchoalveolar lavage fluid and elevated levels of pro-inflammatory cytokines in lung tissues. Ni ions also increased extracellular matrix protein levels, including those of type I collagen and MMP9 in mouse lung tissues and cell lines. Moreover, Ni ions promoted the phosphorylation of AKT in this mouse model. The effect of increased collagen levels and MMP9 expression was inhibited by blocking the AKT phosphorylation. Together, these findings suggest AKT activation as a critical contributor to this Ni-exacerbated pulmonary fibrotic process. PMID- 29185216 TI - Heterogeneous activation of peroxymonosulfate by hierarchical CuBi2O4 to generate reactive oxygen species for refractory organic compounds degradation: morphology and surface chemistry derived reaction and its mechanism. AB - Activation of peroxymonosulfate (PMS) by a novel hierarchical CuBi2O4 generated reactive oxygen radical for degradation refractory organic compounds in aqueous solution, which would be controlled by the morphology and surface chemistry of solid catalyst. It's found that the activation ability of CuBi2O4 toward PMS was highly dependent on the morphology and surface hydroxyl group, as using rhodamine B (RhB) as the model compound. The spherical CuBi2O4, which possessed higher density of surface hydroxyl group, exhibited better catalytic activity in RhB degradation than scattered cluster CuBi2O4, and as-prepared CuBi2O4 could efficiently activated PMS to degrade RhB within a wide pH range as an absolute heterogeneous process. The emerging organic chemicals, including bisphenol A, 1H benzotriazole, and carbamazepine, could also be effectively removed in this novel CuBi2O4/PMS. Furthermore, activation mechanism of PMS by as-prepared CuBi2O4 was proposed, the existence of surface hydroxyl group bonded with Cu(II), and inward electron transfer cycling reaction between Cu(II)/Cu(I) facilitated the effective activation of PMS to generate SO4.- and .OH. In addition, the intermediates of RhB formed in this process were identified by silylation derivatation-GC-MS and LC-high-resolution MS/MS, and degradation pathway was proposed.

AB - Livestock and poultry breeding industry is one of the main economic pillars of northeastern China. However, the amount of pollutants produced is much higher than that in other parts of China. Through a questionnaire survey, indoor experiment, and outdoor experiment, it was found that the resource utilization rate of livestock and poultry manure in the northeastern region is low, with the pollution of livestock and poultry breeding mainly including air and water pollution. The alarm level of cultivated land and manure is II. While the livestock and poultry breeding is relatively concentrated area, its level is higher than grade II. Based on the pollution status of small farms, biogas can be produced through fermentation, along with the preparation of organic fertilizer, to completely utilize the manure and straw, while obtaining higher economic value, and effectively controlling the pollution from livestock and poultry breeding.

In nature, pesticide remainders are subjected to the chemical, physical, and biochemical degradation process, but because of its elevated stability and some cases water solubility, the pesticide residues persist in the ecosystem. The removal of pesticides has been performed through several techniques classified under biological, chemical, physical, and physicochemical process of remediation from different types of matrices, such as water and soil. This review provides a description of older and newer techniques and materials developed to remove specific pesticides according to previous classification, which range from bioremediation with microorganisms, clay, activated carbon, and polymer materials to chemical treatment based on oxidation processes. Some types of pesticides that have been removed successfully to large and small scale include, organophosphorus, carbamates, organochlorines, chlorophenols, and synthetic pyrethroids, among others. The most important characteristics, advantages, and disadvantages of techniques and materials for removing pesticides are described in this work.

AB - Water pollution caused by the discharge of hazardous textile effluents is a serious environmental problem worldwide. In order to assess the pollution level of the textile effluents, various physico-chemical parameters were analyzed in the textile wastewater and agricultural soil irrigated with the wastewater (contaminated soil) using atomic absorption spectrophotometer and gas chromatography-mass spectrometry (GC-MS) analysis that demonstrated the presence of several toxic heavy metals (Ni, Cu, Cr, Pb, Cd, and Zn) and a large number of organic compounds. Further, in order to get a comprehensive idea about the toxicity exerted by the textile effluent, mung bean seed germination test was performed that indicated the reduction in percent seed germination and radicle plumule growth. The culturable microbial populations were also enumerated and found to be significantly lower in the wastewater and contaminated soil than the ground water irrigated soil, thus indicating the biotic homogenization of indigenous microflora. Therefore, the study was aimed to develop a cost effective and ecofriendly method of textile waste treatment using native soil bacterium, identified as Arthrobacter soli BS5 by 16S rDNA sequencing that showed remarkable ability to degrade a textile dye reactive black 5 with maximum degradation of 98% at 37 degrees C and pH in the range of 5-9 after 120 h of incubation. PMID- 29185222 TI - Health risk evaluation of heavy metals in green land soils from urban parks in Urumqi, northwest China. AB - Here, we sampled, tested, and analyzed heavy metals in soil obtained from green land in urban parks of Urumqi. Analysis included soil nutrient contents, particle size distribution, and health risks of heavy metal contaminants. Results showed that (1) organic matter and rapidly available phosphorus contents of all samples ranged from 6.07-58.34 and 6.52-116.15 mg/kg, with average values of 31.26 and 36.24 mg/kg, respectively; (2) silt (particle size 20-200 MUm) comprised most of the particle distribution, accounting for 46.56-87.38% of the total, and the remaining particles were clay particles (0-20 MUm) and sand (200-2000 MUm); (3) calculations of HQing, HQinh, and HQderm for eight heavy metals in three exposure patterns revealed values less than 1 for children and adults, indicating a level of carcinogenic risk for these heavy metals; and (4) calculating the carcinogenic risks of nickel, chromium, and cadmium through breathing pathway indicating no potential carcinogenic risk for any of the three. This research showed high soil nutrient content, providing fertile ground for plant growth in the green land of these urban parks. However, measures such as using sprinklers and increased green vegetation areas have been proposed to improve soil texture. This research can serve as a reference point for soil environmental protection efforts as well as future plant growth in urban Urumqi parks. PMID- 29185223 TI - Role of nature reserves in giant panda protection. AB - Giant panda (Ailuropoda melanoleuca) is a flagship species in nature conservation of the world; to protect this species, 67 nature reserves have been established in China. To evaluate the protection effect of giant panda nature reserves, we analyzed the variation of giant panda number and habitat area of 23 giant panda nature reserves of Sichuan province based on the national survey data released by State Forestry Administration and Sichuan Forestry Department. Results showed that from the third national survey to the fourth, giant panda number and habitat area of 23 giant panda nature reserves of Sichuan province failed to realize the significant increase. Furthermore, we found that the total population growth rate of 23 nature reserves in the last 12 years was lower than those of the province total of Sichuan and the national total of China, and the total habitat area of the 23 nature reserves was decreasing in the last 12 years, but the province total and national total were all increasing. We propose that giant panda protection should pay more attention to how to improve the protective effects of nature reserves.

AB - The renewable energy sources are considered the vital factor to promote global green business. The environmental cost of doing business is the pre-requisite to analyze sustainable policies that facilitate the eco-minded entrepreneurs to produce healthier goods. This study examines the impact of renewable energy sources (i.e., hydro energy, biofuel energy, and wind energy) on the environmental cost of doing business in a panel of BRICS (Brazil, Russian Federation, India, China, and South Africa) countries, for the period of 1995 2015. The study employed principal component analysis to construct an "integrated environmental index" by using three alternative and plausible factors including carbon dioxide emissions, fossil fuel energy consumption, and chemicals used in the manufacturing process. The environmental index is used as an interactive term with the three cost of doing business indicators including business disclosure index, the cost of business start-up procedures, and logistics performance index to form environmental cost of doing business (ECDB) indicators. The results of three-stage least squares (3SLS) estimator show that foreign direct investment (FDI) inflows supported the green business while trade openness deteriorates the environment, which partially validates the "pollution haven hypotheses (PHH)" in a panel of countries. There is no evidence for environmental Kuznets curve (EKC) hypothesis; however, there is a monotonic decreasing relationship between per capita income and ECDB indicators. The hydro energy supports the sustainable business environment, while biofuel consumption deteriorates the environmental impact on the cost of business start-up procedures. Finally, wind energy subsequently affected the ECDB indicators in a panel of BRICS countries. The overall results conclude that growth factors and energy sources both have a considerable impact on the cost of doing business; therefore, there is a momentous need to formulate sustainable policy vista to magnetize green business across countries. PMID- 29185225 TI - Imperative roles of halotolerant plant growth-promoting rhizobacteria and kinetin in improving salt tolerance and growth of black gram (Phaseolus mungo). AB - The salinity stress causes a major threat for plant growth, yield, and biomass production. The present study was designed to assess the effect of exogenously applied kinetin and halotolerant plant growth-promoting rhizobacteria (H-PGPR) on alleviation of salt stress in black gram (Phaseolus mungo). A total of 15 rhizobacterial isolates obtained from a salt-affected area were analyzed for their capability to improve growth of P. mungo plants growing in greenhouse conditions. Out of the tested rhizobacteria, the two bacterial isolates which exhibited maximum growth potential were screened and their growth-promoting attributes were evaluated. The role of screened H-PGPR and/or kinetin (8 and 10 MUM) was evaluated in P. mungo plants irrigated with three levels of brackish water (S1 = 3, S2 = 5, and S3 = 7 dSm-1) under field condition. Salt stress reduced transpiration rate, stomatal conductance, salt tolerance index, growth, leaf area, photosynthetic pigments, leaf relative water content (LRWC), biomass production, and seed yield in subjected plants. Conversely, the salinized plants treated with kinetin and/or H-PGPR exhibited improved levels of chlorophyll contents, LRWC, root growth, shoot growth, biomass production, and seed yield. The H-PGPR and/or kinetin supplementation also reduced electrolyte leakage in salt-stressed plants. Overall, the present findings will be of great value to recognize the mechanism of salt stress alleviation in P. mungo plants under the influence of H-PGPR and/or kinetin. PMID- 29185226 TI - Assessment of three plant-based biodiesels using a Daphnia magna bioassay. AB - Biodiesel is an alternative fuel that is gradually replacing petroleum-based diesel use. Although biodiesel is considered friendlier to the environment, the potential toxic effects of biodiesel to aquatic organisms are still uncertain due to the wide range of feedstocks used to generate the fuel. The aquatic cladoceran Daphnia magna (D. magna) has been commonly used as a lethal and/or sub-lethal toxicological model organism in ecological risk assessments for contaminated water environments. In this work, we evaluated whether significant differences exist in the sensitivity of freshwater aquatic life to different biodiesels. The acute toxicity of three plant-based biodiesels was investigated using D. magna over a 96-h period. In addition, diesel fuel was tested as a reference. Increased immobility was observed as time progressed following exposure. Testing revealed of the four fuel products, diesel proved most toxic to D. magna, with half maximal effective concentration (EC50) values of 4.7 MUg/mL (24 h) and 3.4 MUg/mL (72 h). Among the biodiesels, safflower methyl biodiesel was most toxic, with EC50 values of 1026 MUg/mL (24 h) and 71 MUg/mL (48 h). Our data indicate that although not all biodiesels were toxic, the short-term exposure of D. magna to sub-lethal concentrations of biodiesels affects their mobility and thus decreases their reproductive potential. Overall, this research provides insights into the sub-lethal effects of biodiesels on an aquatic organism. PMID- 29185227 TI - Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the management of pseudomyxoma peritonei: A single-center experience. AB - BACKGROUND AND AIMS: Pseudomyxoma peritonei (PMP) results from perforated appendiceal tumors. It is usually diagnosed preoperatively by imaging. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), although aggressive long procedure with high complications rate, was considered the optimal treatment. This study is aiming to study the role of CRS and HIPEC in the management of PMP and assess the outcome. METHODS: This is a retrospective study which was conducted at King Faisal Hospital and Research Center, a tertiary care hospital during the period from November 2008 to June 2016. Approval of the Research Advisory Council was obtained. Forty-one procedures of CRS and HIPEC were performed in 38 patients. Using the open abdomen technique, CRS was performed using standard peritonectomy procedures and visceral resections directed toward the complete elimination of tumors from abdominopelvic cavity. HIPEC was performed using mitomycin C in a dose of 30 mg/m2 and allowed to circulate in abdominopelvic cavity for 90 min at 41.0 to 42.2 degrees C. RESULTS: Forty-one procedures were performed in 38 patients. Three procedures were done as repeat CRS and HIPEC. No perioperative mortality. Cystoscopy and bilateral ureteric stents in 35 procedures (85.5%). Hospital stay (range 9-85 days) average is 21 days. Follow up period is 1-84 months, and median follow up is 54 months. Five-year survival rate is 92%. Median 5-year disease-free survival rate is 60%. Two patients died during the follow up period by septic shock and one patient died from disease progression. CONCLUSION: CRS and HIPEC is well tolerated and feasible management for PMP. PMID- 29185228 TI - Deceased donor liver transplant: Experience from a public sector hospital in India. AB - BACKGROUND: Deceased donor liver transplant (DDLT) is an uncommon procedure in India. We present our experience of DDLT from a public sector teaching hospital. METHODS: A retrospective analysis of all DDLT was performed from April 2012 till September 2016. Demographics, intraoperative, donor factors, morbidity, and outcome were analyzed. RESULTS: During the study period, 305 liver transplants were performed, of which 36 were DDLT (adult 32, pediatric 4; 35 grafts; 1 split). The median age was 42.5 (1-62) years; 78% were men. The median donor age was 28 (1-77) years; 72.2% were men. About 45% of organs were procured from outside of Delhi and 67% of all grafts used were marginal. Three of 38 liver grafts (7.8%) were rejected due to gross steatosis. Commonest indication was cryptogenic cirrhosis (19.4%). The median model for end-stage liver disease sodium and pediatric end-stage liver disease scores were 23.5 (9-40) and 14.5 (9 22), respectively. Median warm and cold ischemia times were 40 (23-56) and 396 (111-750) min, respectively. Major morbidity of grade III and above occurred in 63.8%. In hospital (90 days), mortality was 16.7% and there were two late deaths because of chronic rejection and biliary sepsis. The overall survival was 77.8% at median follow up of 8.6 (1-54) months. CONCLUSIONS: DDLT can be performed with increasing frequency and safety in a public sector hospital. The perioperative and long-term outcomes are acceptable despite the fact that most organs were extended criteria grafts. PMID- 29185229 TI - Overexpression of insulin receptor substrate-4 is correlated with clinical staging in colorectal cancer patients. AB - Insulin receptor substrate-4 (IRS-4), a poorly studied member of the IRS family, may play an important role in colorectal cancer (CRC) tumourigenesis. The aim of this pilot study was to elucidate the potential role of IRS-4 in colorectal carcinogenesis by evaluating IRS-4 expression in different types of colorectal tumours (n = 20) and comparing its expression to normal mucosa (n = 20). Tissue samples were collected from 18 patients with CRC and 2 with precancerous lesions (tubulovillous adenomas), all of whom were undergoing potentially curative surgery. IRS-4 expression was evaluated using immunohistochemical staining and compared to clinicopathological features. In normal colonic crypts, the subcellular localization of IRS-4 varied from the crypt base compartment to the surface epithelium. Nuclear IRS-4 staining decreased while non-nuclear IRS-4 increased as cells approached the top of the crypt. In the patients studied, colorectal tumours showed a significant (p < 0.001) increase of IRS-4 expression compared with adjacent normal tissue. Furthermore, nuclear IRS-4 intensity of CRC patients was significantly (p < 0.0001) higher in colonic tumoural tissue than in paired normal specimens. Tumour expression of IRS-4 in CRC patients was positively associated with T (p < 0.0001) and N (p < 0.05), of TNM (tumour and nodes and metastasis) staging system. Taken together, these results suggest that increase of IRS-4 expression may be involved to some extent in colorectal cancer.

AB - OBJECTIVES: To determine the prevalence and genotype distribution of rotaviruses in children presenting to authors' hospital in Middle Black Sea region of Turkey. The results may supply important information about vaccine studies in Turkey. METHODS: Rotavirus antigen was detected by latex agglutination test and rotavirus RNA was detected by RT-PCR test. On the other hand, rotavirus positive samples were genotyped by semi-nested multiplex polymerase chain reaction. RESULTS: The highest rate of rotavirus positivity (46.9%) was observed among children in the 13 to 24 mo age group. All the positive-strains were in G1-4, G8-9, P [4], P [8], and P [9] genotypes. The most common G and P combination in present study was G9P[8] (n = 24, 28.9%). CONCLUSIONS: The present results indicated that the most prevalent genotypes were G1, G9, P8, G9P[8] and G1P[8] in authors' region. Rotavirus vaccines used in this region must include mainly these genotypes. PMID- 29185231 TI - Translating Asthma: Dissecting the Role of Metabolomics, Genomics and Personalized Medicine. AB - The management of asthma has largely stagnated over the last 25 years, but we are at the dawning of a new age wherein -omics technology can help us manage the disease objectively and rationally. Even in this new scientific age, getting the basics of asthma management right remains essential. The new technologies which can be applied to multiple biological samples include genomics (study of the genome), transcriptomics (gene transcription), lipidomics, proteomics and metabolomics (lipids, proteins and metabolites, respectively) and breathomics, using exhaled breath as a source of biomarkers, which is of particular interest in view of its non-invasive nature in pediatrics. Important applications will include the diagnosis of airways disease, including its components; the pathways driving airway pathology; monitoring the response to treatment; and measuring future risk (asthma attacks, poor lung growth trajectory). With the advent of a wide range of novel biologicals to treat asthma, -omics technology to personalize therapy will be especially important. The U-BIOPRED (Europe) and SARP (USA) groups have been most active in this field, especially using bronchoscopically obtained samples to perform cluster analyses to define new asthma endotypes. However, stability over time and consistency between investigators is imperfect. This is perhaps unsurprising; results of biomarker studies in asthma will be a composite of the underlying disease, the (variable) effects of adverse drivers such as allergen exposure and pollution, the effects of treatment, and the effects of adherence or otherwise to treatment. Ultimately, the aim should be an exhaled breath based tool with a rapid result that can be used as a routine in the clinic. However, at the moment, there are as yet no clinical applications in children of -omics technology. PMID- 29185232 TI - Impaired taste sensation in type 2 diabetic patients without chronic complications: a case-control study. AB - PURPOSE: Few and contradictory data suggest changes in taste perception in type 2 diabetes (T2DM), potentially altering food choices. We, therefore, analyzed taste recognition thresholds in T2DM patients with good metabolic control and free of conditions potentially impacting on taste, compared with age-, body mass index-, and sex-matched normoglycemic controls. METHODS: An ascending-concentration method was used, employing sucrose (sweet), sodium chloride (salty), citric acid (sour), and quinine hydrochloride (bitter), diluted in increasing concentration solutions. The recognition threshold was the lowest concentration of correct taste identification. RESULTS: The recognition thresholds for the four tastes were higher in T2DM patients. In a multiple regression model, T2DM [beta = 0.95; 95% CI 0.32-1.58; p = 0.004 (salty); beta = 0.61; 0.19-1.03; p = 0.006 (sweet); beta = 0.78; 0.15-1.40; p = 0.016 (sour); beta = 0.74; 0.22-1.25; p = 0.006 (bitter)] and waist circumference [beta = 0.05; 0.01-0.08; p = 0.012 (salty); beta = 0.03; 0.01-0.05; p = 0.020 (sweet); beta = 0.04; 0.01-0.08; p = 0.020 (sour); beta = 0.04; 0.01-0.07; p = 0.007 (bitter)] were associated with the recognition thresholds. Age was associated with salty (beta = 0.06; 0.01-0.12; p = 0.027) and BMI with sweet thresholds (beta = 0.06; 0.01-0.11; p = 0.019). CONCLUSIONS: Taste recognition thresholds were higher in uncomplicated T2DM, and central obesity was significantly associated with this impairment. Hypogeusia may be an early sign of diabetic neuropathy and be implicated in the poor compliance of these patients to dietary recommendations. PMID- 29185233 TI - Estimating Prevalence and Healthcare Utilization for Treatment-Resistant Depression in Japan: A Retrospective Claims Database Study. AB - BACKGROUND: Major depressive disorders (MDDs) including treatment-resistant depression (TRD) are common disabling conditions, but data on their epidemiology in Japan are limited. This study investigated the incidence, epidemiology, and direct medical costs of TRD and pharmaceutically-treated depression (PTD) in Japan to increase our health economic understanding of this phenotype of MDD. METHODS: A retrospective cohort study from a private health insurance claims database estimated the 1-year incidence of PTD and TRD and described the health services used and direct medical costs associated with these conditions. RESULTS: In the year from 1 April 2012 through 31 March 2013, we identified 1143 incident PTD cases among 98,552 eligible subjects, i.e. 11.59 cases/1000 patient-years. Of the PTD patients, 51.4% were women. Within the 1-year observation interval 137 patients failed more than two antidepressive treatment approaches and thus developed TRD. Though co-morbid conditions and age were similar among PTD and TRD patients, medical costs per patient (patient-year) during their treatment intervals were 1.01 million JPY (0. 540 million JPY) in the TRD population and 0.643 JPY million JPY (0.645 million JPY) in the PTD population who did not convert into TRD. CONCLUSIONS: This study describes the PTD and TRD patient populations in a large claims database in Japan and highlights an unmet medical need for the treatment of TRD to provide better preventative measures and interventions for the treatment of depression. PMID- 29185234 TI - Newly Isolated Lactobacilli strains from Algerian Human Vaginal Microbiota: Lactobacillus fermentum Strains Relevant Probiotic's Candidates. AB - Lactobacilli strains are considered as a preventive means for treatment of vaginal infections or post-antibiotic treatment to repopulate the vaginal mucosa. This study aimed at establishing the vaginal lactobacillus profile of Algerian women with different vaginal diseases. Afterwards, lactobacilli isolated from swabs were in vitro characterized for their probiotic hallmarks. This prospective study allowed isolation of 44 Lactobacillus strains and 160 potentially pathogens, among which are Escherichia coli (50 isolates), Staphylococcus sp. (38 isolates), Enterococcus sp. (16 isolates), and Candida sp. (56 isolates). All Lactobacilli strains were characterized for their antagonism, adhesion to polystyrene, and resistance to acidity and bile. Consequently, six Lactobacillus strains (Lb. fermentum 5LB4, 5LB10, 5LB12, Lb. plantarum 5LB2, 5LB11, and Lactobacillus sp. 4LB9) were moderately or weakly adherent, and 35 potentially pathogens exhibited weak to strong adhesion to polystyrene. Antagonism was recorded for 36 Lactobacillus strains towards E. coli 6E2, S. aureus 7S3, Enterococcus sp. 5EN8, and Candida albicans C1 used as indicator organisms. Finally, Lb. fermentum 9LB6, 4LB16, and 10LB1 and Lb. plantarum 9LB4 were remarkable for their inhibitory activity, absence of hemolytic potential, and for their resistance to acidity (pH 1.5) and bile (0.5%) harsh conditions.

PMID- 29185236 TI - An Automated System Combining Safety Signal Detection and Prioritization from Healthcare Databases: A Pilot Study. AB - INTRODUCTION: Signal detection from healthcare databases is possible, but is not yet used for routine surveillance of drug safety. One challenge is to develop methods for selecting signals that should be assessed with priority. AIM: The aim of this study was to develop an automated system combining safety signal detection and prioritization from healthcare databases and applicable to drugs used in chronic diseases. METHODS: Patients present in the French EGB healthcare database for at least 1 year between 2005 and 2015 were considered. Noninsulin glucose-lowering drugs (NIGLDs) were selected as a case study, and hospitalization data were used to select important medical events (IME). Signal detection was performed quarterly from 2008 to 2015 using sequence symmetry analysis. NIGLD/IME associations were screened if one or more exposed case was identified in the quarter, and three or more exposed cases were identified in the population at the date of screening. Detected signals were prioritized using the Longitudinal-SNIP (L-SNIP) algorithm based on strength (S), novelty (N), and potential impact of signal (I), and pattern of drug use (P). Signals scored in the top 10% were identified as of high priority. A reference set was built based on NIGLD summaries of product characteristics (SPCs) to compute the performance of the developed system. RESULTS: A total of 815 associations were screened and 241 (29.6%) were detected as signals; among these, 58 (24.1%) were prioritized. The performance for signal detection was sensitivity = 47%; specificity = 80%; positive predictive value (PPV) 33%; negative predictive value = 82%. The use of the L-SNIP algorithm increased the early identification of positive controls, restricted to those mentioned in the SPCs after 2008: PPV = 100% versus PPV = 14% with its non-use. The system revealed a strong new signal with dipeptidylpeptidase-4 inhibitors and venous thromboembolism. CONCLUSION: The developed system seems promising for the routine use of healthcare data for safety surveillance of drugs used in chronic diseases. PMID- 29185237 TI - Using Human 'Experiments of Nature' to Predict Drug Safety Issues: An Example with PCSK9 Inhibitors. AB - INTRODUCTION: When a new drug enters the market, its full array of side effects remains to be defined. Current surveillance approaches targeting these effects remain largely reactive. There is a need for development of methods to predict specific safety events that should be sought for a given new drug during development and postmarketing activities. OBJECTIVE: We present here a safety signal identification approach applied to a new set of drug entities, inhibitors of the serine protease proprotein convertase subtilisin/kexin type 9 (PCSK9). METHODS: Using phenome-wide association study (PheWAS) methods, we analyzed available genotype and clinical data from 29,722 patients, leveraging the known effects of changes in PCSK9 to identify novel phenotypes in which this protein and its inhibitors may have impact. RESULTS: PheWAS revealed a significantly reduced risk of hypercholesterolemia (odds ratio [OR] 0.68, p = 7.6 * 10-4) in association with a known loss-of-function variant in PCSK9, R46L. Similarly, laboratory data indicated significantly reduced beta mean low-density lipoprotein cholesterol (- 14.47 mg/dL, p = 2.58 * 10-23) in individuals carrying the R46L variant. The R46L variant was also associated with an increased risk of spina bifida (OR 5.90, p = 2.7 * 10-4), suggesting that further investigation of potential connections between inhibition of PCSK9 and neural tube defects may be warranted. CONCLUSION: This novel methodology provides an opportunity to put in place new mechanisms to assess the safety and long-term tolerability of PCSK9 inhibitors specifically, and other new agents in general, as they move into human testing and expanded clinical use. PMID- 29185238 TI - Agreement Among Different Scales for Causality Assessment in Drug-Induced Liver Injury. AB - BACKGROUND AND OBJECTIVE: The causality assessment of drug-induced liver injury (DILI) remains a challenge and eagerly awaits the development of reliable hepatotoxicity biomarkers. None of the different available algorithms used for the causality assessment of DILI has been universally accepted as the gold standard. This study was conducted to examine the agreement among different causality assessment scales in reporting DILI. METHODS: The World Health Organization-Uppsala Monitoring Center (WHO-UMC), Naranjo, Roussel Uclaf Causality Assessment Method (RUCAM), Maria & Victorino (M & V) and Digestive Disease Week-Japan (DDW-J) assessment scales were used to compare the causalities in all the reported cases of DILI in our adverse drug reaction (ADR) monitoring centre from January 2014 to June 2017. The probability of the causality assessment was classified as 'definite', 'probable', 'possible' and 'unlikely'. The agreement obtained among the causality assessments was analysed using the weighted kappa (kappa w) test. RESULTS: A total of 33 cases of DILI were included in our analyses. Anti-tubercular therapy (ATT) and methotrexate were the drugs that most commonly caused DILI. The overall agreement among the different scales was poor. The best agreement was found between RUCAM and DDW-J scales (kappa w: 0.685). CONCLUSION: There were discrepancies among the different causality scales in assessing DILI. This might be due to the different definitions of causality criteria and subjective variability during assessment. A personalised assessment scale incorporating the latest information on specific risk factors and evidence based criteria for DILI is warranted.

PMID- 29185240 TI - Insufficient recruitment and premature discontinuation of clinical trials in Switzerland: qualitative study with trialists and other stakeholders. AB - AIMS OF THE STUDY: Premature discontinuation occurs in about 25% of randomised clinical trials in Switzerland; it mainly affects investigator-initiated trials and is mostly due to problems with recruitment of patients. The aim of this study was to qualitatively investigate reasons for trial discontinuation due to poor patient recruitment and suggestions to address those reasons in the Swiss context. METHODS: We conducted semi-structured interviews with trialists whose trials were discontinued because of recruitment problems, other experienced trialists, and stakeholders in clinical research in Switzerland. Interviews were audio-recorded, transcribed verbatim, and anonymised. We analysed the transcripts using deductive coding and built up themes that were continuously discussed within the research team. RESULTS: Of 65 invited Swiss trialists and stakeholders, 39 (60%) agreed to be interviewed and contributed to this analysis. We identified four main themes of reasons for poor recruitment: (1) Switzerland has a decentralised healthcare system with many small hospitals and few patients per hospital, many research regulations, no standardisation of medical records across hospitals, and a heterogeneous ethics assessment of study protocols. There is little collaboration of different stakeholders in clinical research and a lack of prioritisation of projects. (2) Limited human and financial resources, especially in the academic setting, compromise research questions and size of clinical trials. When funding is used up this typically triggers discontinuation of already delayed clinical trials. (3) Investigators face underdeveloped research networks and a limited collaborative attitude among clinical researchers. They typically embark on clinical studies with a great deal of optimism but insufficient preparation. (4) Swiss patients have universal health coverage and many treatment options. Negative media coverage of clinical research and a lack of accessible information for patients about ongoing clinical studies frequently make participation in clinical trials less attractive. More interactive structures and collaboration across stakeholders were mentioned as potential solutions to tackle the problems. CONCLUSIONS: Recruitment of participants into clinical trials in Switzerland is challenging because of various, often interlinked factors related to the Swiss health system, available funding, investigators, and patients. Common goals and concerted efforts by involved stakeholders appear necessary to achieve improvement. PMID- 29185241 TI - Quality indicators of colorectal cancer care in southern Switzerland: results from a population-based study. AB - AIM OF THE STUDY: Assessing the quality of cancer care (QoCC) has become increasingly relevant to providers, regulators and purchasers of healthcare worldwide. The aim of this study was to assess adherence to validated quality indicators (QIs) for colorectal cancer (CRC) in a population-based setting, and to compare results with the available literature. METHODS: All colorectal cancers diagnosed between 1 January 2011 and 31 December 2012 were identified from the files of the population-based Ticino Cancer Registry, southern Switzerland. We computed 12 core QIs, approved by use of the validated Delphi methodology and for which all the necessary medical documentation was available or only minor data collection was still needed to complete the analysis: three for diagnosis, two for pathology and seven for treatment (surgery, oncology and radiotherapy). Each QI was analysed as proportion (%) with 95% confidence interval, following the approach "available case analysis". RESULTS: A total of 474 colorectal cancers were identified: 86.9% patients were diagnosed after they reported symptoms, 90.2% had preoperative colonoscopy, 8.7% underwent emergency surgery, 97.2% had a surgical resection with tumour-free margins, and for 86.6% at least 12 lymph nodes were examined. The overall 30-day postoperative mortality was 3.6% and 66.7% of locally advanced rectal cancers benefited of neoadjuvant radiotherapy +/ chemotherapy. CONCLUSIONS: Our study showed the feasibility of assessing QoCC using Cancer Registry population-based data. Results according to the clinical domain of pathology, surgery, oncology and radio-oncology in southern Switzerland are generally positive and encouraging, sometimes more favourable in comparison with other international studies, except the very low proportion of patients with a diagnosis based on opportunistic screening (8.6%). Considering the lack in the literature of population-based studies, further national and international reports are urgently needed for comparative analysis as well as standardisation of QI definition is absolutely necessary for inter-regional comparative goals.

AB - Scientific advances and innovative targeted drugs, especially biologics, have revolutionised the treatment of many diseases. In oncology in particular, previously acute or lethal conditions have come to be considered chronic as new treatments have led to longer life expectancies and a lower rate of years lived with disability. These advances, however, come with rising costs in a resource constrained environment. To achieve cost containment, reimbursement for in-vitro diagnostics (IVDs) is increasingly coming under pressure because they are perceived as a cost factor rather than as a tool to reduce expenditure in the long term. In this conceptual paper, we propose four possible interventions from an industry perspective that may contribute to increase effectiveness of IVD use to counteract increasing healthcare expenditures. These are: (1) fostering prevention, screening, early diagnosis and therapy; promoting (2) comprehensive and (3) stratified disease management; and (4) using targeted treatment alongside companion diagnostics. We conclude that the implementation of policies that promote a fee-for-outcome model rather than fee-for-service reimbursement can support sustainable healthcare. PMID- 29185243 TI - Risk of adverse outcome in patients referred by emergency medical services in Switzerland. AB - AIMS OF THE STUDY: Comparison of outcomes between different emergency medical services (EMS) is difficult and lacking in Switzerland. Therefore, knowledge about the inherent risks of EMS-referred patients is important. Targeted interventions may benefit these patients by optimising resource allocation. We therefore aimed to study outcomes in EMS-referred patients presenting to a Swiss emergency department (ED). METHODS: Prospective observational study in all patients presenting to the ED of Basel University Hospital. Mode of referral was recorded (EMS or other). Univariate and multivariate linear, Poisson and logistic regression models were used. Crude and age/gender adjusted associations between mode of referral and outcomes were calculated. Outcomes were shown for admission, length of stay (LOS), in-hospital, and 1-year mortality. RESULTS: Of 5634 patients presenting in the inclusion period, 4703 were screened, 4544 were included and 4287 were followed up for 365 days. Associations between EMS referral and several adverse outcomes were found and expressed as odds ratios (ORs) and geometric mean ratios (GMRs): hospital admission (OR 3.8, 95% CI 3.2 4.5; p <0.001), intensive care unit (ICU) admission (OR 4.2, 95% CI 3.2-5.5, p <0.001), ED-LOS (GMR 1.2, 95% CI 1.1-1.2; p <0.001), in-hospital mortality (OR 6.4, 95% CI 2.9-15.6; p <0.001) and 1-year mortality (OR 2.3, 95% CI 1.7-3.0; p <0.001). CONCLUSION: Patients referred by EMS have higher odds of admission to hospital and ICU, a longer ED LOS, and higher short- and long-term mortalities than the general ED population. PMID- 29185244 TI - Monobodies as possible next-generation protein therapeutics - a perspective. AB - Over the past two decades, hundreds of new somatic mutations have been identified in tumours, and a few dozen novel cancer therapeutics that selectively target these mutated oncoproteins have entered clinical practice. This development has resulted in clinical breakthroughs for a few tumour types, but more commonly patients' overall survival has not improved because of the development of drug resistance. Furthermore, only a very limited number of oncoproteins, largely protein kinases, are successfully targeted, whereas most non-kinase oncoproteins inside cancer cells remain untargeted. Engineered small protein inhibitors offer great promise in targeting a larger variety of oncoproteins with better efficacy and higher selectivity. In this article, I focus on a promising class of synthetic binding proteins, termed monobodies, that we have shown to inhibit previously untargetable protein-protein interactions in different oncoproteins. I will discuss the great promise alongside the technical challenges inherent in converting monobodies from potent pre-clinical target validation tools to next generation protein-based therapeutics.

PMID- 29185246 TI - Is there a role for procalcitonin in differentiating uncomplicated and complicated diverticulitis in order to reduce antibiotic therapy? A prospective diagnostic cohort study. AB - AIMS OF THE STUDY: While studies show that antibiotic treatment for uncomplicated diverticulitis seems to have no benefit, most experts advocate antimicrobial therapy for complicated diverticulitis. However, even for uncomplicated diverticulitis, most clinicians are very reluctant to withhold antibiotics. Biomarkers could help to guide antibiotic therapy as this approach has been shown to be effective for acute respiratory infections. In this diagnostic cohort study we evaluated whether procalcitonin could be a biomarker to distinguish complicated from uncomplicated cases of diverticulitis. METHODS: Complicated diverticulitis was defined as having abscess formation or perforation diagnosed by abdominal computed tomography (CT) scan. In all patients with suspected diverticulitis, procalcitonin values were measured at admission and on day 2. These values were blinded for clinicians, and treatment was carried out according to the physician's judgement. Two groups (complicated vs uncomplicated diverticulitis) were defined. Patients who had received antibiotic treatment before admission were excluded. Difference in procalcitonin values was calculated for both groups using the Mann-Whitney test. Receiver operating characteristics (ROC) were calculated to determine cut-off values for procalcitonin according to the gold standard (abdominal CT scans). RESULTS: 115 patients were included for analysis. 35 patients (30%) suffered from complicated diverticulitis. The median procalcitonin value for uncomplicated diverticulitis was significantly lower compared to complicated diverticulitis (median 0.05, interquartile range [IQR] 0.05-0.06 ng/l vs median 0.13, IQR 0.05-0.23 ng/l; p <0.0001). In the ROC analysis, the sensitivity and specificity were 81% and 91% when the highest procalcitonin value (days 1 and 2) was considered, with a cut-off value of 0.1 ng/l. CONCLUSION: Procalcitonin was able to differentiate with a high sensitivity and specificity between complicated and uncomplicated cases of diverticulitis when combined with abdominal CT scans. As most clinicians still treat uncomplicated diverticulitis with antibiotics, procalcitonin could be an interesting parameter for guiding therapy and decreasing antibiotic usage. This should be further evaluated in randomised trials. PMID- 29185247 TI - Technical comment on: Gawinecka et al. Acute aortic dissection: pathogenesis, risk factors and diagnosis.

PMID- 29185249 TI - Temporal trends of postpartum haemorrhage in Switzerland: a 22-year retrospective population-based cohort study. AB - AIM: Postpartum haemorrhage (PPH) is one of the leading causes of maternal morbidity and mortality. Studies have reported an increase in incidence of postpartum haemorrhage in recent years. Our goal was to investigate changes in the incidence of postpartum haemorrhage (PPH) and its risk factors in Switzerland from 1993 to 2014. METHODS: This population-based retrospective cohort study used data from the national Swiss Hospital in-patient database for obstetric and gynaecological hospital admissions - "Arbeitsgemeinschaft Schweizer Frauenkliniken" (ASF Statistik). All patients with deliveries between January 1993 and December 2014 were included. We used the database codes to identify patients with PPH, maternal factors, pregnancy-related and delivery-related factors. Significant changes in temporal trends were determined using Mantel Haenszel test for trend. Multivariable logistic regression analyses were conducted to assess PPH and risk factors. RESULTS: Births complicated by PPH in Switzerland increased from 2.5% in 1993 to 4.5% in 2014 (p <0.001), paralleled by an increase in uterine atony. Failure to progress during the second stage of labour (odds ratio [OR] 1.5, 95% confidence interval [CI] 1.5-1.6), oxytocin augmentation (OR 1.2, 95% CI 1.2-1.3), vacuum extraction (OR 1.1, 95% CI 1.1 1.2), and especially abnormally invasive placenta (OR 10.4, 95% CI 9.5-11.5) and placenta praevia (OR 4.9, 95% CI 432-5.6) were factors with the highest risk for postpartum haemorrhage. CONCLUSIONS: Postpartum haemorrhage is a relatively common and potentially dangerous obstetric complication with increasing incidence over the last two decades in Switzerland. Its increase over time has been paralleled by an increase in uterine atony. PMID- 29185250 TI - Management of hepatitis C in decentralised versus centralised drug substitution programmes and minimally invasive point-of-care tests to close gaps in the HCV cascade. AB - BACKGROUND: In Switzerland, intravenous drug use accounts for the majority of hepatitis C virus (HCV) infections. Early HCV treatment prevents further transmissions and reduces morbidity and mortality due to decompensated liver cirrhosis and hepatocellular carcinoma. Nevertheless, patients in drug substitution programmes are often insufficiently screened and treated. AIM: The aim was to compare the current state of HCV management in centralised and decentralised drug substitution programmes of the canton Aargau. Objectives were human immunodeficiency virus (HIV) and HCV prevalence, compliance with guidelines and gaps in the HCV cascade, as well as feasibility/acceptance/validity of HIV/HCV rapid tests on finger-prick blood and noninvasive liver fibrosis assessment with Fibroscan(r). METHODS: For the cross-sectional study, in June 2013, questionnaires and free rapid tests for HIV (Determine(r)) and HCV (OraQuick(r)) that used capillary blood (finger-stick) were sent to 161 physicians providing drug substitution treatment for 631 patients. Free liver fibrosis assessment with Fibroscan(r) by a member of the study team was offered to all patients. Additionally, patients were directly recruited by the study team in the heroin substitution programme and several addiction clinics visited every 4-6 months, as well as in the Infectious Diseases Outpatient Clinic (questionnaire, rapid tests and Fibroscan(r) in the same session). RESULTS: Between July 2013 and July 2015, 205 (32.5%) of the 631 patients receiving opioid substitution in the canton Aargau were enrolled, 192 (93.7%) with HIV/HCV rapid tests and 167 (81.5%) with Fibroscan(r). Acceptance of Fibroscan(r) was higher when offered in the same session (94.1 vs 69.2%). Overall, 77.8% had ever used intravenous drugs. HCV seroprevalence was 53.7% (109/203), HCV RNA prevalence 27.8%. Overall, 7.4% (15/202) were HIV infected, all of whom were HCV co-infected and under antiretroviral treatment. Of the 205 patients included, 104 (50.7%) were recruited in a decentralised setting (family practice / pharmacy) and 101 (49.3%) in a centralised setting (heroin programme, addiction clinic, Infectious Diseases Outpatient Clinic). Compliance with guidelines (regular HIV/HCV screening, workup of HCV-positive patients, availability of HAV/HBV serology) was consistently lower in the decentralised setting, characterised by a higher proportion of females, longer median time in the programme, lower percentage of daily attendance, ever-use of intravenous drugs and HIV and HCV infections. We identified several gaps in the HCV cascade: 23.9% (49/205) had never been HCV screened; 18.9% (18/95) of the HCV positive patients had no HCV RNA test. Of the 61 patients developing chronic HCV infection, 19.7% (12) were not HCV genotyped, 52.5% (32) had no liver fibrosis assessment (liver biopsy) and 54.1% (33) never received treatment; 25.0% (7/28) did not achieve a sustained virological response with interferon-based treatment. The 192 HCV rapid tests showed a sensitivity of 90.4% (94/104; 95% confidence interval 84.7-96.1%) and a specificity of 100% (88/88), and provided 14 new HCV diagnoses. Eight of ten patients with a false negative HCV rapid test were HCV RNA negative (2 unknown). Among the 88.6% (39/44) currently HCV RNA-positive individuals with valid Fibroscan(r) results, 24 (61.5%) had a liver stiffness <7.5 kPa. Both HIV co-infection and alcohol overconsumption doubled the risk of severe fibrosis/cirrhosis in HCV positive patients. CONCLUSION: In contrast to HIV, HCV transmission among intravenous drug users is still ongoing. The management of hepatitis C in drug substitution patients needs improvement, especially in family practices. Minimally invasive "point-of-care" diagnostics such as the HCV antibody rapid test using capillary blood and mobile Fibroscan(r) can close some of the gaps in the HCV cascade. HCV RNA determination in capillary blood is still an unmet need. A "one-stop strategy" might improve linkage to care. Restricting the new, highly efficient (90-100% sustained virological response for all genotypes) direct-acting antivirals to patients with at least stage F2 fibrosis withholds treatment from two thirds of the chronically infected and prevents us from reaching the WHO goal of 80% treatment uptake necessary to eliminate hepatitis C by 2030. PMID- 29185251 TI - Ultrasound indications for maternal STORCH testing in pregnancy. AB - AIMS OF THE STUDY: Fetal abnormalities found on ultrasonography lead to a variety of diagnostic procedures, including a panel of serologies to detect possible maternal STORCH infections encompassing syphilis, Toxoplasma gondii, rubella, cytomegalovirus, herpes simplex, and others (human immunodeficiency virus, hepatitis B and C, parvovirus B19, enterovirus, varicella zoster, and Leptospira interrogans). The value of indiscriminate testing for infections upon the detection of fetal ultrasound abnormalities has been questioned. The aim of this study was to review the ultrasonographic abnormalities leading to maternal STORCH panels at the obstetrics department of a university hospital. METHODS: Laboratory results of all maternal STORCH tests requested after the detection of ultrasonographic abnormalities during a 5-year period (2008-2012) were analysed. The main ultrasound findings possibly caused by congenital infection were noted, and the outcomes of confirmed maternal and fetal infections were studied. RESULTS: In our study period, 392 maternal STORCH tests were performed because of fetal ultrasound abnormalities. The most common findings leading to STORCH testing were intrauterine growth restriction (30.4%) including microcephaly (1.5%), polyhydramnios (14.8%), and intrauterine fetal demise (13.3%). Maternal STORCH infections were found in 3.4% of growth-restricted fetuses, 5.2% of polyhydramnios, and 1.9% of intrauterine fetal demise. The leading aetiologies were cytomegalovirus and parvovirus B19. All seven congenital infections displayed multiple ultrasonographic abnormalities. CONCLUSION: Ultrasonographic findings associated with fetal infection are neither sensitive nor specific. Testing for STORCH infections should take into account exposure history, clinical signs and symptoms, obstetric history, and fetal ultrasound findings, but with special attention paid to cytomegalovirus and parvovirus B19. PMID- 29185252 TI - Multidrug resistant (or antimicrobial-resistant) pathogens - alternatives to new antibiotics? AB - For the last few decades, multidrug resistance has become an increasing concern for both Gram-positive and Gram-negative bacteria. The number of new molecules has dramatically decreased and antibiotic resistance is now a priority in the international community. Facing this new threat, a large number of new as well as "old" solutions are now being discussed in the medical community to propose an alternative to antibiotic treatments. A first option is to potentiate the effect of existing molecules through combinations to circumvent the individual molecule resistance. The second option is to neutralise either the infectious agent itself or its by-products using specific antibodies. A third option is to use the pathogen signaling mechanism and inhibit the production of virulence factor through quorum sensing inhibition. A fourth pathway would be to interact with the patient's microbiota using either probiotics or faecal transplantation to modulate the innate immune response and improve response to the infectious challenge, but also to act directly against colonisation by resistant bacteria by replacing the flora with susceptible strains. The last option is to target the bacteria using phage therapy. Phages are natural viruses that specifically infect target bacteria independently of any antibiotic-susceptibility profile. In this review, we will discuss each of these options and provide the scientific rationale and the available clinical data. In the majority of cases, these treatments represent an interesting approach but not the ultimate solution to multiresistance. Well-performed clinical trials are still missing and the major priority remains to promote good use and appropriate stewardship of antibiotics to decrease resistance. PMID- 29185253 TI - Cost-effectiveness of sacubitril/valsartan in chronic heart-failure patients with reduced ejection fraction. AB - AIMS: We aimed to assess the cost effectiveness of sacubitril/valsartan compared to angiotensin-converting enzyme inhibitors (ACEIs) for the treatment of individuals with chronic heart failure and reduced-ejection fraction (HFrEF) from the perspective of the Swiss health care system. METHODS: The cost-effectiveness analysis was implemented as a lifelong regression-based cohort model. We compared sacubitril/valsartan with enalapril in chronic heart failure patients with HFrEF and New York-Heart Association Functional Classification II-IV symptoms. Regression models based on the randomised clinical phase III PARADIGM-HF trials were used to predict events (all-cause mortality, hospitalisations, adverse events and quality of life) for each treatment strategy modelled over the lifetime horizon, with adjustments for patient characteristics. Unit costs were obtained from Swiss public sources for the year 2014, and costs and effects were discounted by 3%. The main outcome of interest was the incremental cost effectiveness ratio (ICER), expressed as cost per quality-adjusted life years (QALYs) gained. Deterministic sensitivity analysis (DSA) and scenario and probabilistic sensitivity analysis (PSA) were performed. RESULTS: In the base case analysis, the sacubitril/valsartan strategy showed a decrease in the number of hospitalisations (6.0% per year absolute reduction) and lifetime hospital costs by 8.0% (discounted) when compared with enalapril. Sacubitril/valsartan was predicted to improve overall and quality-adjusted survival by 0.50 years and 0.42 QALYs, respectively. Additional net-total costs were CHF 10 926. This led to an ICER of CHF 25 684. In PSA, the probability of sacubitril/valsartan being cost effective at thresholds of CHF 50 000 was 99.0%. CONCLUSION: The treatment of HFrEF patients with sacubitril/valsartan versus enalapril is cost effective, if a willingness-to-pay threshold of CHF 50 000 per QALY gained ratio is assumed.

PMID- 29185255 TI - Informal caregiving, work-privacy conflict and burnout among health professionals in Switzerland - a cross-sectional study. AB - INTRODUCTION: Health professionals were found to have an elevated burnout risk compared to the general population. Some studies also reported more emotional exhaustion - a component of burnout - for health professionals with informal caregiving responsibilities for children (double-duty child caregivers) or adults (double-duty adult caregivers) or a combination of both (triple-duty caregivers) compared to health professionals without informal caregiving roles (formal caregivers). However, the potential mediating effect of the work-privacy conflict in this relationship as well as differences between occupational groups have not yet been studied in healthcare settings. AIM: To assess the impact of informal caregiving on burnout risk among health professionals and whether this relationship is mediated by work-privacy conflict or differs between occupational groups. METHODS: Data were collected through an employee survey in six hospitals from German-speaking Switzerland in 2015/2016. Mediation analyses were performed using linear mixed models with fixed effects for caregiving situation and work privacy conflict as well as random effects for hospitals. RESULTS: Triple-duty caregivers were found to have a significantly higher burnout risk compared to formal caregivers only. Work-privacy conflict did not mediate this relationship, except among the "other health professionals" group. CONCLUSION: Additional and large-scale studies focusing on the combination of formal and informal caregiving roles are needed to better understand its effect on burnout among healthcare professionals and to evaluate the role of work-privacy conflict.

PMID- 29185257 TI - Optimal mesenchymal stem cell delivery routes to enhance neurogenesis for the treatment of Alzheimer's disease: optimal MSCs delivery routes for the treatment of AD. AB - Alzheimer's disease (AD) is a common cause of dementia. Alzheimer's disease (AD) is characterized by progressive loss of memory in addition to cortical atrophy. Despite decades of research and therapeutic trials in AD, an effective treatment is yet to be developed. Mesenchymal stem cells (MSCs) have emerged as promising tools for the treatment of AD, and clinical trials have been completed or are in progress. MSCs secrete various cytotropic factors that may exert beneficial effects in AD. The route of administration is an important factor to enhance MSC based treatment effects for AD. Among various routes, the intracerebroventricular route may possess several advantages such as the activation of neurogenesis, compared to other routes for AD treatments. In this review, we will focus on recent pre-clinical and clinical advances in MSC-based treatment of AD, specifically in relation to enhancement of endogenous neurogenesis. PMID- 29185258 TI - Corticosteroids for chronic inflammatory demyelinating polyradiculoneuropathy. AB - BACKGROUND: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a progressive or relapsing and remitting paralysing illness, probably due to an autoimmune response, which should benefit from corticosteroid treatment. Non randomised studies suggest that corticosteroids are beneficial. Two commonly used corticosteroids are prednisone and prednisolone. Both are usually given as oral tablets. Prednisone is converted into prednisolone in the liver so that the effect of the two drugs is usually the same. Another corticosteroid, dexamethasone, is more potent and is used in smaller doses. The review was first published in 2001 and last updated in 2015; we undertook this update to identify any new evidence. OBJECTIVES: To assess the effects of corticosteroid treatment for CIDP compared to placebo or no treatment, and to compare the effects of different corticosteroid regimens. SEARCH METHODS: On 8 November 2016, we searched the Cochrane Neuromuscular Specialised Register, Cochrane Central Register of Controlled Trials, MEDLINE, and Embase for randomised trials of corticosteroids for CIDP. We searched clinical trials registries for ongoing trials. SELECTION CRITERIA: We included randomised controlled trials (RCTs) or quasi-RCTs of treatment with any corticosteroid or adrenocorticotrophic hormone for CIDP, diagnosed by an internationally accepted definition. DATA COLLECTION AND ANALYSIS: Two authors extracted data from included studies and assessed the risk of bias independently. The intended primary outcome was change in disability, with change in impairment after 12 weeks and side effects as secondary outcomes. We assessed strength of evidence using the GRADE approach. MAIN RESULTS: One non-blinded RCT comparing prednisone with no treatment in 35 eligible participants did not measure the primary outcome for this systematic review. The trial had a high risk of bias. Neuropathy Impairment Scale scores after 12 weeks improved in 12 of 19 participants randomised to prednisone, compared with five of 16 participants randomised to no treatment (risk ratio (RR) for improvement 2.02 (95% confidence interval (CI) 0.90 to 4.52; very low-quality evidence). The trial did not report side effects in detail, but one prednisone treated participant died.A double-blind RCT comparing daily standard-dose oral prednisolone with monthly high-dose oral dexamethasone in 40 participants reported none of the prespecified outcomes for this review. The trial had a low risk of bias, but the quality of evidence was limited as it came from a single small study. There was little or no difference in number of participants who achieved remission (RR 1.11; 95% CI 0.50 to 2.45 in favour of monthly dexamethasone; moderate-quality evidence), or change in disability or impairment after one year (low-quality evidence). Change of grip strength or Medical Research Council (MRC) scores demonstrated little or no difference between groups (moderate-quality to low-quality evidence). Eight of 16 people in the prednisolone group and seven of 24 people in the dexamethasone group deteriorated. Side effects were similar with each regimen, except that sleeplessness was less common with monthly dexamethasone (low-quality evidence) as was moon facies (moon-shaped appearance of the face) (moderate-quality evidence).Experience from large non-randomised studies suggests that corticosteroids are beneficial, but long-term use causes serious side effects. AUTHORS' CONCLUSIONS: We are very uncertain about the effects of oral prednisone compared with no treatment, because the quality of evidence from the only RCT that exists is very low. Nevertheless, corticosteroids are commonly used in practice, supported by very low-quality evidence from observational studies. We also know from observational studies that corticosteroids carry the long-term risk of serious side effects. The efficacy of high-dose monthly oral dexamethasone is probably little different from that of daily standard-dose oral prednisolone. Most side effects occurred with similar frequencies in both groups, but with high-dose monthly oral dexamethasone moon facies is probably less common and sleeplessness may be less common than with oral prednisolone. We need further research to identify factors that predict response. PMID- 29185260 TI - Robotic single site radical hysterectomy plus pelvic lymphadenectomy in gynecological cancers. AB - OBJECTIVE: To evaluate the feasibility and the safety of robotic single-site radical hysterectomy (RSSRH) plus pelvic lymphadenectomy (PL) in endometrial or cervical cancer. METHODS: Patients with endometrial cancer (EC) International Federation of Gynecology and Obstetrics (FIGO) stage II, early cervical cancer (ECC) FIGO stage IB1 or locally advanced cervical cancer (LACC) FIGO stage IB2 IIB with clinical response >=50% after neo-adjuvant chemotherapy (NACT) were enrolled in a prospective cohort trial. All cases were performed using the da Vinci Si Surgical Single Site System(r). RESULTS: Between April 2014 and November 2016, twenty patients were included in our pilot study. Three and 17 patients underwent type B1 or C1 RSSRH plus PL, respectively. The median age of patients was 46 years (range, 36-68 years) and the median body mass index was 23.5 kg/m2 (range, 19.1-36.3 kg/m2). The median total operative time was 190 minutes (range, 90-310 minutes). The median blood loss was 75 mL (range, 20-700 mL) and the median number of pelvic lymph nodes removed was 16 (range, 5-27). No laparoscopic/laparotomic conversions were reported and the median time to discharge was 6 days (range, 4-16 days). No intra-operative complications occurred while 4 (20%) post-operative complications were reported: one pelvic abscess, one lymphorrea, one bowel perforation, and one vaginal dehiscence. CONCLUSION: RSSRH plus PL is technically feasible in patients affected by gynecological cancer. PMID- 29185259 TI - Role of lymphadenectomy in intermediate-risk endometrial cancer: a matched-pair study. AB - OBJECTIVE: To assess the impact of lymph node dissection (LND) on morbidity, survival, and cost for intermediate-risk endometrial cancers (IREC). METHODS: A multicenter retrospective cohort of 720 women with IREC (endometrioid histology with myometrial invasion <50% and grade 3; or myometrial invasion >=50% and grades 1-2; or cervical involvement and grades 1-2) was carried out. All patients underwent hysterectomy and bilateral salpingo-oophorectomy. A matched pair analysis identified 178 pairs (178 with LND and 178 without it) equal in age, body mass index, co-morbidities, American Society of Anesthesiologist score, myometrial invasion, and surgical approach. Demographic data, pathology results, perioperative morbidity, and survival were abstracted from medical records. Disease-free survival (DFS) and overall survival (OS) was analyzed using Kaplan Meier curves and multivariate Cox regression analysis. Cost analysis was carried out between both groups. RESULTS: Both study groups were homogeneous in demographic data and pathologic results. The mean follow-up in patients free of disease was 61.7 months (range, 12.0-275.5). DFS (hazard ratio [HR]=1.34; 95% confidence interval [CI]=0.79-2.28) and OS (HR=0.72; 95% CI=0.42-1.23) were similar in both groups, independently of nodes count. In LND group, positive nodes were found in 10 cases (5.6%). Operating time and late postoperative complications were higher in LND group (p<0.05). Infection rate was significantly higher in no-LND group (p=0.035). There were no statistical differences between both groups regarding operative morbidity and hospital stay. The global cost was similar for both groups. CONCLUSION: Systematic LND in IREC has no benefit on survival, although it does not show an increase in perioperative morbidity or global cost. PMID- 29185261 TI - Pazopanib monotherapy in the treatment of pretreated, metastatic uterine sarcoma: a single-center retrospective study. AB - OBJECTIVE: In the treatment of metastatic soft tissue sarcoma (STS), pazopanib is considered a standard treatment after failure of chemotherapy. We retrospectively investigated outcomes of pazopanib in patients with metastatic uterine STS. METHODS: A retrospective study was performed on 35 consecutive patients with uterine STS treated with oral pazopanib 800 mg daily as salvage therapy for metastatic disease between September 2013 and December 2015. Endpoints included response rate, survival, and safety. RESULTS: Among 35 patients, 27 (77%) had a histologic diagnosis of leiomyosarcoma (LMS) and the median age was 57 years (range, 36-70). Median number of metastatic sites was one (range, 1-5) with lung as the most frequently involved site. Pazopanib was generally well-tolerated: the major hematologic toxicity was grade 1/2 anemia (14%). Among the non-hematologic toxicities, grade 1/2 stomatitis was most commonly observed (22%), followed by fatigue and hypertension. Objective response and stable disease were observed in 10 (29%) and 11 (31%) patients, respectively. However, most cases of clinical response were observed in patients with LMS: 33% for LMS, 20% for undifferentiated pleomorphic sarcoma, and 0% for endometrial stromal sarcoma. Median progression-free and overall survivals were 5.8 months (95% confidence interval [CI]=3.6-8.1) and 20.0 months (95% CI=11.6-28.4), respectively. CONCLUSION: In this "real-world" retrospective study, salvage therapy with pazopanib demonstrated clinically relevant efficacy and tolerability in unselected patients with uterine STS. Although it is encouraging that outcomes for Korean patients with uterine STS were similar to those reported in the phase III trial, the clinical benefit was limited to LMS. PMID- 29185262 TI - Mutational analysis of KRAS and its clinical implications in cervical cancer patients. AB - OBJECTIVE: The predictive and prognostic role of KRAS mutations in cervical cancer remains inconclusive. The aim of this study was to explore the clinicopathological and prognostic relevance of KRAS mutations in invasive cervical cancers (ICC). METHODS: Reverse transcription polymerase chain reaction (PCR) and Sanger sequencing were employed to detect KRAS mutations in 876 ICC patients. Quantitative real-time PCR was used to detect human papillomavirus (HPV) 16 and HPV 18. RESULTS: Non-synonymous mutations of KRAS were identified in 30 (3.4%) patients. These mutations were more common in non-squamous cell carcinoma than in squamous cell carcinoma (SCC) (8.2% vs. 2.2%, respectively, p<0.001) and were associated with HPV 18 infection (p=0.003). The prevalence of mutations was highest (18.2%) in the uncommon histological subtypes followed by adenocarcinoma (AC, 7.3%) and adenosquamous carcinoma (ASC, 5.8%). During the median follow-up of 55 months, compared to patients with wild-type KRAS, a greater percentage of patients with mutant KRAS relapsed (20.0% vs. 42.9%, respectively, p=0.007). The 3-year relapse-free survival was poorer in patients with mutant KRAS than in patients without KRAS mutations (57.1% vs. 81.9%, respectively, p=0.001). Furthermore, the multivariate analysis showed that the presence of a KRAS mutation was an independent predictor for disease recurrence (hazard ratio [HR]=2.064; 95% confidence interval [CI]=1.125-3.787; p=0.019). CONCLUSION: KRAS mutations were predominant in non-SCCs of the cervix and were associated with HPV 18 infection. A combination of KRAS mutation detection and HPV genotyping would be useful in identifying patient with poor prognosis for further interventions. PMID- 29185263 TI - Oncologic outcomes of adjuvant chemotherapy alone after radical surgery for stage IB-IIA cervical cancer patients. AB - OBJECTIVE: To evaluate the oncologic outcomes of adjuvant chemotherapy (CT) alone after radical surgery. METHODS: We retrospectively reviewed the medical records of patients who underwent type C radical hysterectomy and pelvic lymphadenectomy with or without paraaortic lymphadenectomy for stage IB-IIA cervical cancer from March 2006 to December 2014 at 2 academic medical centers in Korea. Adjuvant CT alone for patients who met the Sedlis criteria or had lymph node (LN) involvement. Chemotherapeutic regimens consisted of either platinum alone or platinum-based combination. RESULTS: A total of 101 consecutive patients were included in the analysis. The median age was 46.0 years (range, 23-73). Seventy four patients (73.3%) were clinically staged as IB1; 23 and 4 patients as IB2 and IIA, respectively. The median number of retrieved pelvic and paraaortic LNs (PALNs) were 55.0 (range, 16-101) and 10.0 (range, 2-30), respectively. LN involvement was observed in 25 patients (24.8%). After the median follow-up of 65 months, 14 patients (13.9%) developed disease recurrence. In all patients, the estimated 3-year disease-free survival (DFS) rate and 5-year overall survival (OS) rate were 90.7% and 90.6%, respectively. In patients who met the Sedlis criteria, the 3-year DFS and 5-year OS rates were 94.6% and 90.6%, respectively. Patients with LN metastasis showed a 3-year DFS rate of 79.4% and a 5-year OS rate of 90.6%. CONCLUSION: Adjuvant CT alone could be reasonable option for patients with surgical-pathologic risk factors after radical surgery in stage IB IIA cervical cancer. PMID- 29185264 TI - Clinical outcomes and risk of recurrence among patients with vaginal intraepithelial neoplasia: a comprehensive analysis of 576 cases. AB - OBJECTIVE: To evaluate the clinical outcomes of vaginal intraepithelial neoplasia (VAIN) and to assess the risk of recurrence and progression to invasive vaginal carcinoma. METHODS: A retrospective review of the clinicopathologic data and clinical outcomes was performed on patients who were diagnosed with VAIN at a single center between January 2000 and July 2016. Demographics, treatments, and clinical outcomes were abstracted from medical records. RESULTS: A total of 576 patients with VAIN1-3 were included in the study analysis. The distribution of VAIN1-3 was as follows: VAIN1 31.1%, VAIN2 45.3%, and VAIN3/carcinoma in situ (CIS) 23.6%. In VAIN1 patients, observation was performed in 29.1% of the cases and 48.8% obtained regression. In VAIN2+ patients, management included observation (3.5%), topical management (6.5%), laser ablation (75.3%), excision (14.1%), and radiotherapy (0.5%) with the following rates of recurrence/progression: 46.2%, 62.5%, 26.4%, 32.7%, and 0%, respectively. Four patients among VAIN3/CIS patients (3.2%) developed invasive vaginal cancer during the follow-up period with a median time to cancer diagnosis of 21.4 months (range, 5.0-44.8 months). On multivariate analysis, high-risk human papillomavirus (HPV) positivity and treatment method were found to be independent risk factors for recurrence and progression (p=0.003 and p=0.001). CONCLUSION: Patients with VAIN are at high-risk of recurrence, but the risk of progression to vaginal cancer is relatively low. Laser or excision provides higher regression rate than topical agent or observation, and high-risk HPV positivity is a risk factor for recurrence. Whatever the treatment method is used, however, the high rate of recurrence warrants long-term follow-up surveillance. PMID- 29185265 TI - Epidemiology of gynecologic cancers in China. AB - Cancer has become a major disease burden across the globe. It was estimated that 4.29 million new incident cases and 2.81 million death cases of cancer would occur in 2015 in China, with the age-standardized incidence rate (ASIR) of 201.1 per 100,000 and age-standardized mortality rate (ASMR) of 126.9 per 100,000, respectively. For females, 2 of the top 10 most common types of cancer would be gynecologic cancers, with breast cancer being the most prevalent (268.6 thousand new incident cases) and cervical cancer being the 7th most common cancer (98.9 thousand new incident cases). The incidence and mortality of gynecologic cancers have been constantly increasing in China over last 2 decades, which become a major health concern for women. Survival rates of gynecologic cancers are generally not satisfactory and decrease along with advancing stage, though national data on survival are still not available. It is of great importance to overview on the epidemiology of gynecologic cancers, which may provide scientific clues for strategy-making of prevention and control, and eventually lowering the incidence and mortality rate as well as improving the survival rate in the future. PMID- 29185266 TI - Are vaginal swabs comparable to cervical smears for human papillomavirus DNA testing? AB - OBJECTIVE: Human papillomavirus (HPV) testing is widely incorporated into cervical cancer screening strategies. Current screening requires pelvic examination for cervical sampling, which may compromise participation. The acceptance could be raised by introducing testing on vaginal swabs. We explored the interchangeability of vaginal swabs and cervical smears for HPV testing, by means of a prospective study conducted in female sex workers (FSWs). Besides, we report on the occurrence of 32 different HPV genotypes in FSW with low-grade squamous intraepithelial lesion (LSIL) or high-grade squamous intraepithelial lesion (HSIL). METHODS: Paired physician-collected vaginal swabs and cervical smears from 303 FSW were tested for HPV using the Abbott RealTime High-Risk HPV assay. Cervical cytology was examined on cervical smears. In case of HSIL/LSIL cytological classification (n=52), both samples were genotyped using INNO-LiPa HPV Genotyping Extra II. RESULTS: The overall prevalence of high-risk (HR)-HPV was 51%. In FSW with HSIL/LSIL cervical cytology, the sensitivity and specificity of vaginal samples for the detection of HR-HPV was 100% and 70% and for probable HR-HPV 100% and 91%. The mean number of genotypes identified in vaginal samples (mean=3.5; 95% confidence interval [CI]=2.8-4.2) was significantly higher than in cervical smear samples (mean=2.6; 95% CI=2.1-3.0) (p=0.001). The most frequently encountered HR-HPV genotypes were HPV16, 31, 51, and 52. CONCLUSION: As our study shows that vaginal swabs are equivalent to cervical smears for the detection of (probable) HR-HPV, vaginal swabs can be used for HPV testing in cervical cancer screening strategies. Given the acceptance of vaginal sampling, this finding offers an opportunity to boost screening coverage. PMID- 29185267 TI - Baseline risk of recurrence in stage I-II endometrial carcinoma. AB - OBJECTIVE: Though there are no evidences that postoperative therapy improves overall survival (OS) in stage I-II endometrial carcinoma, many women receive postoperative radiation or chemotherapy. This study aimed to investigate the baseline risk of recurrence after complete resection without any adjuvant therapies and to suppose the validity of postoperative therapy for stage I-II endometrial carcinoma. METHODS: Charts for patients with stage I-II endometrial carcinoma who underwent operation without postoperative therapy between January 2005 and December 2011 were retrospectively reviewed and the baseline risk of recurrence and prognosis were assessed. Risk classifications were performed according to European Society for Medical Oncology (ESMO) clinical practice guidelines and Japanese guideline written by Japan Society of Gynecologic Oncology Group. RESULTS: Among 374 patients who underwent complete resection, 311 were evaluable. Five-year recurrence rates by ESMO and Japanese were 2.6% and 3.1% in low-risk, 9.2% and 6.6% in intermediate-risk and 13.5% and 13.8% in high risk group (p=0.003 and 0.015, respectively). High-risk group had worse OS compared with low- and intermediate-risk groups (5-year OS, low: 97.9% and 97.6%, intermediate: 97.9% and 98.8%, and high: 89.5% and 87.5%; p=0.003 and 0.008, respectively). Independent predictive factors of recurrence were age over 60 years, type 2 (estrogen-independent) and peritoneal cytology. CONCLUSION: ESMO and Japanese risk classification similarly stratify the baseline risk of recurrence. Patients with stage I-II endometrial carcinoma, especially low- and intermediate-risk diseases, have low recurrence rate and favorable OS, and the benefit of postoperative therapy might be small. PMID- 29185268 TI - Quality and quantity metrics of pelvic lymph node metastasis and risk of para aortic lymph node metastasis in stage IB-IIB cervical cancer. PMID- 29185269 TI - Risk stratification models for para-aortic lymph node metastasis and recurrence in stage IB-IIB cervical cancer. AB - OBJECTIVE: To examine the surgical-pathological predictors of para-aortic lymph node (PAN) metastasis at radical hysterectomy, and for PAN recurrence among women who did not undergo PAN dissection at radical hysterectomy. METHODS: This is a retrospective analysis of a nation-wide cohort study of surgically-treated stage IB-IIB cervical cancer (n=5,620). Multivariate models were used to identify independent surgical-pathological predictors for PAN metastasis/recurrence. RESULTS: There were 120 (2.1%) cases of PAN metastasis at surgery with parametrial involvement (adjusted odds ratio [aOR]=1.65), deep stromal invasion (aOR=2.61), ovarian metastasis (aOR=3.10), and pelvic nodal metastasis (single node aOR=5.39 and multiple-node aOR=33.5, respectively) being independent risk factors (all, p<0.05). Without any risk factors, the incidence of PAN metastasis was 0.9%, while women exhibiting certain risk factor patterns (>20% of the study population) had PAN metastasis incidences of >=4%. Among 4,663 clinically PAN negative cases at surgery, PAN recurrence was seen in 195 (4.2%) cases that was significantly higher than histologically PAN-negative cases (2.5%, p=0.046). In clinically PAN-negative cases, parametrial involvement (adjusted hazard ratio [aHR]=1.67), lympho-vascular space invasion (aHR=1.95), ovarian metastasis (aHR=2.60), and pelvic lymph node metastasis (single-node aHR=2.49 and multiple node aHR=8.11, respectively) were independently associated with increased risk of PAN recurrence (all, p<0.05). Without any risk factors, 5-year PAN recurrence risk was 0.8%; however, women demonstrating certain risk factor patterns (>15% of the clinically PAN-negative population) had 5-year PAN recurrence risks being >=8%. CONCLUSION: Surgical-pathological risk factors proposed in this study will be useful to identify women with increased risk of PAN metastasis/recurrence. PMID- 29185270 TI - Impact of lymph node ratio on survival in stage III ovarian high-grade serous cancer: a Turkish Gynecologic Oncology Group study. AB - OBJECTIVE: The purpose of this study was to investigate the prognostic value of lymph node ratio (LNR) in patients with stage III ovarian high-grade serous carcinoma (HGSC). METHODS: A multicenter, retrospective department database review was performed to identify patients with ovarian HGSC at 6 gynecologic oncology centers in Turkey. A total of 229 node-positive women with stage III ovarian HGSC who had undergone maximal or optimal cytoreductive surgery plus systematic lymphadenectomy followed by paclitaxel plus carboplatin combination chemotherapy were included. LNR, defined as the percentage of positive lymph nodes (LNs) to total nodes recovered, was stratified into 3 groups: LNR1 (<10%), LNR2 (10%<=LNR<50%), and LNR3 (>=50%). Kaplan-Meier method was used to generate survival data. Factors predictive of outcome were analyzed using Cox proportional hazards models. RESULTS: Thirty-one women (13.6%) were classified as stage IIIA1, 15 (6.6%) as stage IIIB, and 183 (79.9%) as stage IIIC. The median age at diagnosis was 56 (range, 18-87), and the median duration of follow-up was 36 months (range, 1-120 months). For the entire cohort, the 5-year overall survival (OS) was 52.8%. An increased LNR was associated with a decrease in 5-year OS from 65.1% for LNR1, 42.5% for LNR2, and 25.6% for LNR3, respectively (p<0.001). In multivariate analysis, women with LNR>=0.50 were 2.7 times more likely to die of their tumors (hazard ratio [HR]=2.7; 95% confidence interval [CI]=1.42-5.18; p<0.001). CONCLUSION: LNR seems to be an independent prognostic factor for decreased OS in stage III ovarian HGSC patients. PMID- 29185271 TI - Prognostic significance of normal-sized ovary in advanced serous epithelial ovarian cancer. AB - OBJECTIVE: We compared survival outcomes of advanced serous type epithelial ovarian cancer (EOC) patients with normal-sized ovaries and enlarged-ovarian tumors by propensity score matching analysis. METHODS: The medical records of EOC patients treated at Samsung Medical Center between 2002 and 2015 were reviewed retrospectively. We investigated EOC patients with high grade serous type histology and International Federation of Gynecology and Obstetrics (FIGO) stage IIIB, IIIC, or IV who underwent primary debulking surgery (PDS) and adjuvant chemotherapy to identify patients with normal-sized ovaries. Propensity score matching was performed to compare patients with normal-sized ovaries to patients with enlarged-ovarian tumors (ratio, 1:3) according to age, FIGO stage, initial cancer antigen (CA)-125 level, and residual disease status after PDS. RESULTS: Of the 419 EOC patients, 48 patients had normal-sized ovary. Patients with enlarged ovarian tumor were younger (54.0+/-10.3 vs. 58.4+/-9.2 years, p=0.005) than those with normal-sized ovary, and there was a statistically significant difference in residual disease status between the 2 groups. In total cohort with a median follow-up period of 43 months (range, 3-164 months), inferior overall survival (OS) was shown in the normal-sized ovary group (median OS, 71.2 vs. 41.4 months; p=0.003). After propensity score matching, the group with normal-sized ovary showed inferior OS compared to the group with enlarged-ovarian tumor (median OS, 72.1 vs. 41.4 months; p=0.031). In multivariate analysis for OS, normal-sized ovary remained a significant factor. CONCLUSION: Normal-sized ovary was associated with poor OS compared with the common presentation of enlarged ovaries in EOC, independent of CA-125 level or residual disease.

PMID- 29185272 TI - Prevalence of human papillomavirus genotypes and precancerous cervical lesions in a screening population in the Republic of Korea, 2014-2016. AB - OBJECTIVE: Knowledge regarding the prevalence and distribution of human papillomavirus (HPV) genotyping in healthy women is important in establishing strategies for cervical cancer screening and HPV vaccination. METHODS: A total of 18,170 women who visited a Korean Medical Institute for health check-ups were recruited retrospectively; they underwent HPV genotyping and conventional cervical cytology. An HPV DNA test was performed using the AnyplexTM II HPV 28 detection system (Seegene) or HPV Liquid Bead Microarray (Osang Healthcare). The distribution of HPV genotypes was assessed according to cervical cytology and age. RESULTS: HPV was detected in 3,037 (16.71%) of the 18,170 women enrolled, and 2,268 (12.48%) were positive for high-risk (HR) HPV. In total, HPV 53 (9.69% of all detected HPV viruses) was the most common type; HPV 58 (7.90%) and 52 (7.81%) were also common. HPV 54 (6.99%) was common in low-risk subjects. Overall and in the normal cytology group, the most common HPV genotype was HPV 53, whereas HPV 58 was more common in women who had atypical squamous cells of undetermined significance or low-grade squamous intraepithelial neoplasia cervical cytology. In addition, HPV 16 was the most common type in cases with high-grade squamous intraepithelial neoplasia (HSIL)/atypical squamous cells cannot exclude HSIL. Among women with normal cytology, 76 of 231 (32.9%) women under 24 years of age were positive for HR HPV, whereas 84 of 852 (9.9%) women aged 55-59 years were positive. CONCLUSION: HPV 53 was the most prevalent genotype in healthy women. Distribution of HPV genotypes varied with cervical cytology and age. Our study provides important baseline data for the recently implemented national HPV vaccination program. PMID- 29185276 TI - Harnessing Imaging to Improve Diagnosis and Treatment of Rheumatic Diseases. PMID- 29185274 TI - Survival benefit of patients with early-stage ovarian carcinoma treated with paclitaxel chemotherapeutic regimens. AB - OBJECTIVE: Adjuvant chemotherapy was introduced in patients with early-stage ovarian cancer (OC). The benefit of standard chemotherapeutic regimens including taxane has not been established. METHODS: Patients with early-stage OC from the National Health Insurance Research database of Taiwan who received platinum plus cyclophosphamide (CP) or platinum plus paclitaxel (PT) for 3-6 cycles were recruited, and the disease-free survival (DFS) and overall survival (OS) were determined. RESULTS: A total of 1,510 early-stage OC patients, including 841 who received CP regimen and 699 who received PT regimen, were included. The 2 groups had a similar estimated probability of 5-year DFS (PT vs. CP, 79.0% vs. 77.6%; p=0.410) and OS (84.6% vs. 84.3%; p=0.691). Patients >50 years of age who received the CP regimen had a lower 5-year DFS than the patients <=50 years of age who received the CP (p<0.001) or PT regimens (p=0.001). Additionally, patients >50 years of age who received the CP regimen had a worse 5-year OS compared with the other 3 groups (p=0.019) (p=0.179 for patients >50 years of age in the PT group; p=0.002 for patients <=50 years of age in the CP group; and p=0.061 for patients <=50 years of age in the PT group). Patients with the CP or PT regimen for 3-5 cycles had a similar 5-year DFS and OS compared to 6 cycles (p>0.050). CONCLUSION: Chemotherapeutic regimens with taxane could be recommended for early-stage OC patients >50 years of age. PMID- 29185277 TI - MRI Findings of the Sacroiliac Joints in Patients with Low Back Pain: Alternative Diagnosis to Inflammatory Sacroiliitis. AB - BACKGROUND: Magnetic resonance imaging (MRI) is the most sensitive imaging modality for the detection of sacroiliitis. Diagnosing sacroiliitis on MRI is not always straightforward and can be challenging in some cases. OBJECTIVES: To evaluate the prevalence of alternative diagnoses suggested by MRI and characterize the MR appearance of the most common ones. METHODS: Consecutive MRI examinations of the sacroiliac joints (SIJ) performed between 2005 and 2012 were retrospectively evaluated for the presence of structural and active sacroiliitis findings according to the Assessment of SpondyloArthritis International Society guidelines. Alternative diagnoses, including degenerative changes, diffuse idiopathic skeletal hyperostosis (DISH), Osteitis condensans ilii (OCI), septic sacroiliitis/discitis, stress reaction as well as anatomic variants, were registered. RESULTS: We evaluated 281 MRI examinations, 116 males, 165 females, average age 44 +/- 15 years. Sacroiliitis was found in 71 examinations (25%) and alternative diagnoses were suggested in 87 (31%) (OCI 8.9%, anatomic variants 5.3%, septic sacroiliitis 5.3%, degenerative findings 4.3%, diffuse idiopathic skeletal hyperostosis [DISH] 1.5%, stress reaction 0.7%, tumor 0.3%). A normal examination was found in the remaining 123 examinations. Patients with alternative diagnoses were older than those with sacroiliitis (62 vs. 47 years of age, respectively, P > 0.05). Alternative pathologies in the SIJ were significantly more common in females (66) than males (21), P < 0.05. CONCLUSIONS: A substantial proportion of patients with suspected sacroiliitis had normal SIJ while the rest were more commonly diagnosed with other pathologies. A referral by an experienced rheumatologist may improve the sensitivity and specificity of this important examination. PMID- 29185275 TI - The feasibility of detecting endometrial and ovarian cancer using DNA methylation biomarkers in cervical scrapings. AB - OBJECTIVE: We hypothesized that DNA methylation of development-related genes may occur in endometrial cancer (EC)/ovarian cancer (OC) and may be detected in cervical scrapings. METHODS: We tested methylation status by quantitative methylation-specific polymerase chain reaction for 14 genes in DNA pools of endometrial and OC tissues. Tissues of EC/normal endometrium, OC/normal ovary, were verified in training set using cervical scrapings of 10 EC/10 OC patients and 10 controls, and further validated in the testing set using independent cervical scrapings in 30 EC/30 OC patients and 30 controls. We generated cutoff values of methylation index (M-index) from cervical scrapings to distinguish between cancer patients and control. Sensitivity/specificity of DNA methylation biomarkers in detecting EC and OC was calculated. RESULTS: Of 14 genes, 4 (PTGDR, HS3ST2, POU4F3, MAGI2) showed hypermethylation in EC and OC tissues, and were verified in training set. POU4F3 and MAGI2 exhibited hypermethylation in training set were validated in independent cases. The mean M-index of POU4F3 is 78.28 in EC and 20.36 in OC, which are higher than that in controls (6.59; p<0.001 and p=0.100, respectively), and that of MAGI2 is 246.0 in EC and 12.2 in OC, which is significantly higher that than in controls (2.85; p<0.001 and p=0.480, respectively). Sensitivity and specificity of POU4F3/MAGI2 were 83%-90% and 69% 75% for detection of EC, and 61% and 62%-69% for the detection of OC. CONCLUSION: The findings demonstrate the potential of EC/OC detection through testing for DNA methylation in cervical scrapings. PMID- 29185278 TI - Styloid Process Elongation on Cervical Spine Computed Tomography is Associated with the Enthesopathy-Related Diseases of Ankylosing Spondylitis and Diffuse Idiopathic Skeletal Hyperostosis. AB - BACKGROUND: Enthesopathy may lead to calcification of the stylohyoid ligament and can cause elongation of the styloid process (SP). OBJECTIVES: To evaluate whether SP elongation is associated with two common enthesitis-related diseases: ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH). METHODS: Cervical spine computed tomography (CT) examinations of patients with DISH (n=64, Resnick criteria), AS (n=24, New York criteria) and a controls (no radiological signs of DISH or AS, n=54) were retrospectively evaluated. The DISH group was further divided into patients with and without cervical DISH. The length of right and left SP was measured independently by two readers on coronal and sagittal curved reformats. The average right and left styloid length and average length per person were compared among the groups. RESULTS: Demographic characteristics were similar between the DISH and control groups (average age 68.2 +/- 15.7, 69.2 +/- 12.7 years, male:female ratio 48:16 and 35:19, respectively, P > 0.05), whereas age was significantly lower (average age: 53 +/- 15 years, P < 0.0001) in the AS group, which was also composed mainly of men. The AS and DISH groups had significantly longer SP compared to controls (AS 37.9 +/- 9.6 mm, DISH 34.4 +/- 9 mm, control 30.3 +/- 10.1 mm, P < 0.05). There was no correlation between age and SP length. Inter-reader reliability of SP measurements was excellent in all groups (ICC = 0.998, P < 0.0001). CONCLUSIONS: SP elongation is associated with both AS and DISH substantiating the enthesopathy related pathophysiology of this finding. PMID- 29185279 TI - Metal-on-Metal Hip Replacement: MRI Signal Intensities of Different Body Tissues and Their Relations to Blood Metal Ion Levels. AB - BACKGROUND: Metal-on-metal total hip prostheses (MoM-THR) have been shown to produce hypersensitivity reactions and fluid collection (pseudotumor) by the hip as well as high blood metal ions levels (BMILs). OBJECTIVES: To evaluate the magnetic resonance imaging (MRI) signal-to-noise ratio (S/N) in selected body tissues around the hip of patients who underwent MoM hip replacement and to correlate to BMILs. METHODS: Sixty-one MRI hip examinations in 54 post-MoM-THR patients (18 males, 36 females, mean age 65 years) were retrospectively evaluated independently by two readers. The mean S/N ratio in a region of interest was calculated for periprosthetic pseudotumor collection (PPC), the bladder, fat, and muscle on axial T1w, FSE-T2w, and short tau inversion recovery (STIR) sequences on the same location. BMILs were retrieved from patient files. RESULTS: PPC was detected in 32 patients (52%) with an average volume of 82.48 mm3. BMIL did not correlate with the presence of PPCs but positively correlated with the PPC's volume. A trend for positive correlation was found between BMILs and S/N levels of STIR images for muscle and bladder as well as for PPC and cobalt levels. A trend for correlation was also seen between BMIL with PPC's T1 w S/N. CONCLUSIONS: Alteration of MRI S/N for different hip tissues showed a tendency for correlation with BMILs, possibly suggesting that metal deposition occurs in the PPC as well as in the surrounding tissues and bladder. PMID- 29185280 TI - The PET-CT Radiological Appearance of Facial Cosmetic Injections: A Pitfall in the Evaluation of the Oncological Patient. AB - BACKGROUND: Facial rejuvenation using different dermal and sub-dermal injectable compounds is a popular cosmetic procedure which may pose a diagnostic dilemma to the radiologist. OBJECTIVES: To describe the appearance of cosmetic facial fillers on PET-CT. METHODS: All PET-CT exams performed between January 2015 and May 2017 in which findings suggestive of prior facial filler procedures was evident and where anamnestic confirmation with the patient was possible were reviewed. RESULTS: We describe five females who had undergone facial filler procedures leading to calcifications around the mouth and nasolabial triangle. CONCLUSIONS: Familiarity with the appearance of such cosmetic procedures on PET CT is of paramount importance in order to avoid misinterpretation of the findings leading to unnecessary apprehension and work-up. PMID- 29185281 TI - Ankylosing Spondylitis and Neck Pain: MRI Evidence for Joint and Entheses Inflammation at the Craniocervial Junction. AB - BACKGROUND: Magnetic resonance imaging (MRI), which has recently become the leading imaging modality in the study of ankylosing spondylitis (AS), has not been evaluated in the assessment of disease-specific changes at the craniocervical junction (CCJ) in patients with AS. OBJECTIVES: To describe the spectrum of active inflammatory lesions at the CCJ using MRI in a cohort of patients with AS and neck pain. METHODS: The study included 18 patients with AS presenting with neck pain and a control group of 9 fibromyalgia patients matched for age and levels of neck pain. All patients underwent a focused rheumatologic examination, X-ray of the cervical spine, and a 3T MRI study, which included STIR, CUBE T2, FSE and FSE FAT SAT sequences before and after administration of gadolinium. RESULTS: The median age of AS patients was 43 years with a median disease duration of 7 years. Fifteen of 18 patients were under biologic treatment. Seven of 18 AS patients had evidence of cervical syndesmophytes on X ray films. Active inflammatory lesions of atlanto-occipital joints and apical and alar ligaments were detected in MRIs in 2 out of the 18 patients with AS and in none of the patients with fibromyalgia. Both AS patients with active inflammation of CCJ detected on MRI received treatment with biological agents prior to and during the study. CONCLUSIONS: Active inflammation of both entheses and joints of the CCJ can be demonstrated by MRI in patients with AS. PMID- 29185282 TI - The Lived Experience of Parkinson's Disease: A Content Analysis of Parkinson's Patients' Blogs. AB - BACKGROUND: Blogs have become a major venue of information sharing and emotional release for people worldwide. Illness blogs are a specific type of blog in which patients describe their experience with illness and coping with disease. Illness blog research has been conducted on several disorders; however, blogs by Parkinson's disease (PD) patients have been neglected. OBJECTIVES: To categorize the characteristics of PD patients from blogs and explore whether we can learn about the medical issues with which they are most concerned, as conveyed through their blog posts. METHODS: Using located PD patients' blogs, we analyzed the contents of 78 blogs, and employed thematic analysis of eight arbitrarily selected blogs. RESULTS: The majority of blog authors in our sample (N=78) were from the United States (42%). The number of blogs written by male and female authors was fairly similar: 49% and 44%, respectively, while gender was unknown for 7%. Blogs were written by both early- and late-onset PD patients. The thematic analysis revealed five major themes: diagnosis, symptoms, treatment, coping mechanisms, and information. CONCLUSIONS: Thematic analysis of blogs by PD patients provided considerable information and insight regarding the experience of these patients, which is significant to other patients and their families, as well as to medical professionals. Further qualitative studies of larger blog samples utilizing data mining techniques are needed to further explore the subjective experiences of patients. PMID- 29185283 TI - Surgical Treatment of Neuroblastoma. AB - BACKGROUND: Neuroblastoma is the most common non-central nervous system (CNS) solid malignant tumor in children. The surgical treatment of high-risk neuroblastoma presents a challenge, and the benefits of aggressive surgical resection have been called into question. OBJECTIVES: To examine our experience with surgical resection of neuroblastoma. METHODS: We report on a retrospective chart review of our preliminary surgical experience in 25 patients with neuroblastoma who underwent surgery performed by a single surgeon at two institutions over a 3 year period. Demographic data, including stage of tumor and risk stratification, were recorded. Primary outcome was total gross resection. Patients were followed for 3 years after surgery. RESULTS: We found that 80% of the patients, including those with high-risk neuroblastoma tumors, had total gross resection of their tumor with minimal operative morbidity and no mortality; 88% had greater than 90% resection of their tumor. Overall, 3 year survival was 84% (21/25). CONCLUSIONS: Resection of neuroblastoma, even large, high-risk, bilateral tumors, was possible when performed by surgical teams with considerable experience. PMID- 29185284 TI - Re-Examining Distal Resection in Colon Cancer. AB - BACKGROUND: In colon cancer, data regarding proximal and distal metastasis to lymph nodes remains scarce. OBJECTIVES: To evaluate lymph node distribution along the longitudinal axis of the colon as related to a tumor to re-examine the common practice of 5 cm proximal and 2 cm distal resection margins. METHODS: We studied 106 patients (53 males and 53 females, mean age 67.9 +/- 10 years) who had undergone left hemicolectomy or sigmoidectomy. Colonic cancer specimens were divided into five zones proximally and distally to the tumor. For each zone, overall lymph node evaluation and ratio was performed. RESULTS: The mean number of retrieved lymph nodes per patient was 24.3 +/- 12, with 54.9% of the nodes concentrated in zone I, 22.1% in zone II, 9.5% in zone III, 10.3% in zone IV, and 3% in zone V. While most positive nodes were found in zone I, significant numbers were also detected in both directions proximally and distally to the tumor. CONCLUSIONS: It seems that longer colonic segments proximally, and especially distally, should be considered for resection to significantly reduce the chances of finding involved lymph node. PMID- 29185286 TI - Lessons Learned from Imaging on Enthesitis in Psoriatic Arthritis. AB - BACKGROUND: Enthesitis is a term that refers to inflammation at tendon, ligament, or joint capsule insertions. The entheses are increasinlgly considered to be the primary site of joint inflammation in the spondyloarthropathies including psoriatic arthritis (PsA). Great advances have occurred in the understanding of enthesopathy, which has resulted in a better understanding of the etiopathogenesis of PsA. Enthesitis is difficult to assess on both clinical examination and on imaging because of the overlap in features between mechanical, degenerative, and inflammatory pathologies. Ultrasonography frequently detects entheseal abnormalities in patients with psoriasis, despite the absence of clinical symptoms of arthropathy and the longitudinal value of such lesions for PsA prediction remains unknown. The role of magnetic resonance imaging (MRI) in the assessment and monitoring of enthesitis is not fully agreed on but it is clearly superior for the assessment of spinal polyenthesitis and for diffuse peri enthseal osteitis that can occur anywhere in the skeleton. Nuclear medicine, including conventional positron-emission tomography (PET) and high-resolution PET scan (hrPET), is more of a research tool for enthesitis and can, for example, help distinguish between PsA and osteoarthritis. Entheseal abnormalities are common in osteoarthritis, which creates diagnostic difficulty from PsA. Entheseal changes, especially on imaging, may also occur in rheumatoid arthritis (RA) and likely reflect the extension of the inflammatory process from the adjacent synovium. The nail is anatomically anchored to the skeleton via a mini-enthesis network. An association between ultrasonography determined distal interphalageal joint (DIP) extensor tendon enthesopathy and clinical nail disease was found, which highlights the pivotal role of the enthesis in this PsA risk factor. This review summarizes the relevant insights and implication of imaging for enthesitis, primarily in PsA but also in other arthropathies.

AB - BACKGROUND: Axial spondyloarthritis (axSpA) covers the stage of non-radiographic axial spondyloarthritis (nr-axSpA) and classic ankylosing spondylitis. The pathognomonic findings of axSpA are mainly inflammatory and osteoproliferative changes in the sacroiliac joints (SIJ) and the spine. Various imaging techniques are being used in daily practice for assessment of disease-specific changes, such as periarticular bone marrow edema, erosions, sclerosis, fat metaplasia and ankylosis in the SIJ or spondylitis, spondylodiscitis, facet joint involvement, or syndesmophytes in the spine of patients with axSpA. Conventional radiographs are still considered the gold standard for assessment of structural changes, while the method of for detection of inflammatory changes is magnetic resonance imaging (MRI). A result for an MRI in the SIJ is considered positive for axSpA when more than one lesion is present on one MRI slice, If there is one lesion only, this should be present on at least two consecutive slices. For the spine, inflammatory lesions should preferably be located in the corner of the vertebral bodies, while occurrence of spondylitis in three or more vertebral corners is considered highly suggestive of axSpA. This review gives a detailed overview about the benefits and limitations of all available imaging techniques in patients with axSpA, explains the usage of imaging techniques in the context of diagnosis and differential diagnosis of the disease, and reports on the potential future trends in the area of imaging of the axial skeleton in patients who are suspicious for this diagnosis.

AB - AIM: The aim of this study was to evaluate the quality and value of web-based information on advance directives. Internet-based information on advance directives was selected because, if it is inaccurate or difficult to understand, patients risk making decisions about their care that may not be followed in practice. METHOD: Two validated health information evaluation tools, the Suitability Assessment of Materials and DISCERN, and a focus group were used to assess credibility, user orientation and effectiveness. FINDINGS: Only one of the 34 internet-based information items on advance directives reviewed fulfilled the study criteria and 30% of the sites were classed as unreadable. In terms of learning and informing, 79% of the sites were considered unsuitable. CONCLUSION: Using health literacy tools to evaluate internet-based health information highlights that often it is not at a functional literacy level and neither informs nor empowers users to make independent and valid healthcare decisions. PMID- 29185292 TI - Long ranging swept-source optical coherence tomography-based angiography outperforms its spectral-domain counterpart in imaging human skin microcirculations. AB - There is an increasing demand for imaging tools in clinical dermatology that can perform in vivo wide-field morphological and functional examination from surface to deep tissue regions at various skin sites of the human body. The conventional spectral-domain optical coherence tomography-based angiography (SD-OCTA) system is difficult to meet these requirements due to its fundamental limitations of the sensitivity roll-off, imaging range as well as imaging speed. To mitigate these issues, we demonstrate a swept-source OCTA (SS-OCTA) system by employing a swept source based on a vertical cavity surface-emitting laser. A series of comparisons between SS-OCTA and SD-OCTA are conducted. Benefiting from the high system sensitivity, long imaging range, and superior roll-off performance, the SS-OCTA system is demonstrated with better performance in imaging human skin than the SD OCTA system. We show that the SS-OCTA permits remarkable deep visualization of both structure and vasculature (up to ~2 mm penetration) with wide field of view capability (up to 18*18 mm2), enabling a more comprehensive assessment of the morphological features as well as functional blood vessel networks from the superficial epidermal to deep dermal layers. It is expected that the advantages of the SS-OCTA system will provide a ground for clinical translation, benefiting the existing dermatological practice.

As well as the professional issues encountered by supervisors in relation to the benefits, the challenges of providing supervision and the action required to make safeguarding supervision a part of the organisational culture are also explored. PMID- 29185295 TI - Complications and survival of megaprostheses after resection of bone metastases. AB - Treatment of bone metastases is often palliative, aiming at pain control and stabilization or prevention of pathological fractures. However, a complete resection with healing purposes can be performed in selected cases. The aim of our work was to evaluate the survival of megaprostheses used for reconstruction after bone metastases. Between January 2001 and March 2015, we implanted 169 Megasystem-C(r) (Waldemar LINK(r) GmbH & Co. KG, Hamburg, Germany) after bone metastasis resection. Patients, 95 females and 74 males, were operated at an average age of 61 (12-87) years for proximal femoral resection in 135 (79.9%) cases, distal femur in 24 (14.2%), proximal tibia in 6 (3.6%), total femur in 3 (1.8%) and intercalary femur in 1 (0.6%). Mostly, breast cancer metastases (30.8%), kidney (17.8%) and lung (14.2%) were treated. At an average follow-up of 21 (1-150) months, we found a 99.4% overall limb salvage and a 96.1% overall survival rate at 1 year, 92.8% at 2 years, and 86.8% at 5 and 10 years. We found 9 (5.3%) mobilization cases of the proximal femoral implant, 3 needed surgical reduction; 2 (1.2%) cases of aseptic loosening of the prosthetic stem; 2 (1.2%) periprotetic infection cases, one requiring a 2-stage revision. Few literature studies have evaluated the survival of megaprosthetic implant in the treatment of bone metastases. Our data show how in this specific context the rate of complications is significantly lower than expected in general orthopedic orthopedic surgery. The use of modular prostheses is a valid reconstructive strategy after bone metastasis resection in selected patients. The rate of short term complications is exceptionally low; further studies will have to confirm this in the longer term. PMID- 29185296 TI - Evaluation of accuracy of bone cuts and implant positioning in total knee arthroplasty using patient specific instrumentation. AB - In the last years new surgical techniques are developing to improve prosthesis positioning, increasing clinical and functional results and reducing invasiveness. In this scenario patient-specific instrumentations have been introduced in order to enhance surgical accuracy and ease of implantation. The purpose of this study was to assess the compliance of the pre-operative planning data with bone resections measured intraoperatively and to evaluate prosthesis positioning in patients undergoing total knee arthroplasty (TKA) using an MRI based pin-guides instrumentation. Thirty consecutive patients (20 women and 10 men) undergoing 30 total knee replacements (20 right- and 10 left-sided knees) were included in this study. The same cemented cruciate ligament sacrificing prosthesis (NexGen LPS, Zimmer, Warsaw, Indiana, USA) was implanted in all patients by a single surgeon using Patient-Specific Instruments (PSI, Zimmer, Warsaw, Indiana, USA). Femoral and tibial bone resections were measured using a manual caliper intra-operatively and compared with the corresponding pre operative values. Each patient underwent A CT examination following surgery in order to investigate individual component positioning. None of the cases was converted from PSI technique to conventional TKA and adequate femoral and tibial bone cuts were performed without the need for intraoperative adjustments. Two outliers were detected among the intra-operative bone cuts measurements. In all patients the size of femoral and tibial prosthetic components, hypothesized at preoperative planning, was confirmed intra-operatively. Two outliers were detected among post-operative CT measurements as for components positioning. PSI system can assist in obtaining good component positioning with reduction of outliers. Despite the small number of patients, our data demonstrate the validity of this patient-specific pin-guides system in TKA and may support repeatable improvements in surgical accuracy. Level of evidence: IV. PMID- 29185297 TI - Comparison between different cell sources and culture strategies for tendon tissue engineering. AB - The aim of this study was to evaluate the effect of an in vitro mechanical stimulation by the use of a bioreactor on an engineered tendon for 7 and 14 days and to analyze the effect of the use of different cell sources: tenocytes, dermal fibroblasts or Adipose-Derived Stem Cells (ASCs), isolated from pig tissues. Histology showed a re-organization of the neo-tissue derived from the three cell populations along the direction of the stimulus. At T7, cells morphology was preserved while an increased cellular suffering at T14 was observed for all cell populations. Tenocytes exhibited higher survival than other cells. A stable immunopositivity for collagen type 1 or 3 at both time points was also observed. In conclusion, dermal fibroblasts and ASCs represent an interesting alternative and in vitro culture with mechanical stimuli may enhance the maturation of a tendon-like tissue. PMID- 29185299 TI - Chemotherapy Agents and Dentistry. PMID- 29185298 TI - The analysis of different scaffolds and the benefit of fibrin glue for tendon tissue engineering at different culture times. AB - This study evaluated a tendon substitute model. Tenocytes were isolated from pig Achilles tendon, seeded onto scaffolds (Opocrin 2%, Typeone 3% and Symatese 2%) and studied by histology, immunofluorescence for collagen type 1 and 3 and biochemical analysis to assess cellularity. The permeability of these compounds was evaluated in the presence or absence of fibrin glue. Opocrin 2% was the best choice for cellular distribution within the scaffolds, which were then cultured for T0, T4, T7 and T10 days. Fibrin glue has been strongly supportive for the survival of cells with a significant increase in DNA content at T10 (P<0.05). Moreover, the synthetic activity of fibrin-free scaffolds was always negative. Lastly, a progressive increase in collagen 1 and 3 with fibrin-glue was observed. However, static culture is not sufficient to support long-term cellular activities and at T10 there is still a lack of organized matrix similar to the native tissue.

AB - Main surgical approaches to the hip have been modified during last decades, in an effort to reduce invasiveness of the surgical procedure and allow a faster rehabilitation. Direct anterior approach is the only approach, which does not require muscle detachment, thus theoretically leading to reduced post-operative pain and allows earlier recovery. The aim of this study was to report a comparison between patients operated with direct anterior approach and postero lateral approach in terms of immediate post-operative and in-hospital records. Pain, operative time, intra- and post-operative complications, blood loss, hospitalization, motor component of the Functional Independence Measure (M-FIM), timed up and go (TUG) test were measured between the two groups and compared. Direct anterior approach showed better results in M-FIM, TUG, hospitalization and blood loss, without any significant difference for intra- and post-operative complications between the 2 groups. This study shows that early post-operative recovery is influenced by the chosen approach. Direct anterior approach showed better outcomes when compared to postero-lateral approach, limited to hospitalization, blood loss, and functional scores. Further comparisons are needed to evaluate direct anterior approach to maintain advantages over postero lateral approach on longer follow-up period. PMID- 29185308 TI - The Occlusion Myth.

PMID- 29185333 TI - In Situ Self-Assembly-Generated 3D Hierarchical Co3O4 Micro/Nanomaterial Series: Selective Synthesis, Morphological Control, and Energy Applications. AB - A simple in situ self-assembly selective synthetic strategy for one-step controllable formation of various three-dimensional (3D) hierarchical Co3O4 micro/nanomaterials with peculiar morphologies, uniform size, and high quality is successfully developed. The morphological control and related impact factors are investigated and clarified in detail. The results further clarify the corresponding mechanisms on the reaction process, product generation, and calcining process as well as the formation of specific morphologies. Furthermore, the superior catalytic properties of these materials are confirmed by two typical Co-based energy applications on the decomposition of an important solid rocket propellant, ammonium perchlorate (AP), and dye-sensitized solar cells (DSSCs). The addition of Co3O4 materials to AP obviously decreases the decomposition temperatures by about 118-140 degrees C and increases the exothermic heat to a great extent. As the substituted counter electrodes of DSSCs, the 3D hierarchical Co3O4 materials exhibit attractive photovoltaic performances. These findings provide a facile and effective way for designing new types of 3D hierarchical materials toward high catalytic activity for energy devices. PMID- 29185334 TI - Selective Charging Behavior in an Ionic Mixture Electrolyte-Supercapacitor System for Higher Energy and Power. AB - Ion-ion interactions in supercapacitor (SC) electrolytes are considered to have significant influence over the charging process and therefore the overall performance of the SC system. Current strategies used to weaken ionic interactions can enhance the power of SCs, but consequently, the energy density will decrease due to the increased distance between adjacent electrolyte ions at the electrode surface. Herein, we report on the simultaneous enhancement of the power and energy densities of a SC using an ionic mixture electrolyte with different types of ionic interactions. Two types of cations with stronger ionic interactions can be packed in a denser arrangement in mesopores to increase the capacitance, whereas only cations with weaker ionic interactions are allowed to enter micropores without sacrificing the power density. This unique selective charging behavior in different confined porous structure was investigated by solid-state nuclear magnetic resonance experiments and further confirmed theoretically by both density functional theory and molecular dynamics simulations. Our results offer a distinct insight into pairing ionic mixture electrolytes with materials with confined porous characteristics and further propose that it is possible to control the charging process resulting in comprehensive enhancements in SC performance. PMID- 29185335 TI - On the Control of Chromophore Orientation, Supramolecular Structure, and Thermodynamic Stability of an Amphiphilic Pyridyl-Thiazol upon Lateral Compression and Spacer Length Variation. AB - The supramolecular structure essentially determines the properties of organic thin films. Therefore, it is of utmost importance to understand the influence of molecular structure modifications on supramolecular structure formation. In this article, we demonstrate how to tune molecular orientations of amphiphilic 4 hydroxy thiazole derivatives by means of the Langmuir-Blodgett (LB) technique and how this depends on the length of an alkylic spacer between the thiazole chromophore and the polar anchor group. Therefore, we characterize their corresponding supramolecular structures, thermodynamic, absorption, and fluorescence properties. Particularly, the polarization-dependence of the fluorescence is analyzed to deduce molecular orientations and their possible changes after annealing, i.e., to characterize the thermodynamic stability of the individual solid state phases. Because the investigated thiazoles are amphiphilic, the different solid state phases can be formed and be controlled by means of the Langmuir-Blodgett (LB) technique. This technique also allows to deduce atomistic supramolecular structure motives of the individual solid phases and to characterize their thermodynamic stabilities. Utilizing the LB technique, we demonstrate that subtle molecular changes, like the variation in spacer length, can yield entirely different solid state phases with distinct supramolecular structures and properties. PMID- 29185336 TI - Fluoropolymer-Based Flexible Neural Prosthetic Electrodes for Reliable Neural Interfacing. AB - We covalently bound fluoropolymer (FP) films by plasma treatment followed by thermal pressing at temperatures below their melting point and fabricated an adhesion-metal-free flexible gold electrode array entirely encapsulated by the FP film, excepting the active electrode openings. The fabricated device was chemically resistant and was modified to have a lower impedance and efficient charge injection capability. The fabricated device was evaluated in vivo in rats and was confirmed to record the epidural epileptiform activity induced by chemical administration. The chemically inert nature of FPs and the gold electrode is expected to facilitate reliable neural interfacing without abiotic issues. Plasma treatment-induced covalent binding of FP films can also be utilized in a variety of applications requiring durability, such as implantable biosensors and sensor platforms operating under chemically harsh environments, including humid conditions. PMID- 29185337 TI - Gold Nanorods Stabilized by Biocompatible and Multifunctional Zwitterionic Copolymer for Synergistic Cancer Therapy. AB - A zwitterionic copolymer between methacryloyloxyethyl phosphorylcholine (MPC) and methacrylic acid (MA), PMAMPC is introduced as a potential versatile polymeric stabilizer for gold nanorods (AuNRs). The MA units in the copolymer serve as built-in feature for multiple functionalization, namely introducing additional thiol groups as active sites for binding with the AuNRs and conjugating with doxorubicin (DOX), an anticancer drug via acid-labile hydrazone linkage. The MPC units, on the other hand, provide biocompatibility and antifouling characteristics. The chemically modified PMAMPC can act as an effective stabilizer for AuNRs yielding PMAMPC-DOX-AuNRs with a fairly uniform size and shape with good colloidal stability. In vitro cytotoxicity suggested that PMAMPC can not only improve the AuNRs biocompatibility, but also decrease DOX toxicity to a certain extent. The PMAMPC-DOX-AuNRs were efficiently internalized inside cancer cells and localized in lysosomes, where DOX was presumably acid-triggered released as monitored by confocal laser scanning microscopic analysis and flow cytometry. Furthermore, the combined photothermal-chemo treatment of cancer cells using PMAMPC-DOX-AuNRs exhibited a higher therapeutic efficacy than either single treatment alone. These results suggested that the PMAMPC-DOX-AuNRs could potentially be applied in pH-triggered drug delivery for synergistic cancer therapy. PMID- 29185338 TI - Universal Multifunctional Nanoplatform Based on Target-Induced in Situ Promoting Au Seeds Growth to Quench Fluorescence of Upconversion Nanoparticles. AB - Construction of a new multifunctional chemo/biosensing platform for small biomolecules and tumor markers is of great importance in analytical chemistry. Herein, a novel universal multifunctional nanoplatform for biomolecules and enzyme activity detection was proposed based on fluorescence resonance energy transfer (FRET) between upconversion nanoparticles (UCNPs) and target-inducing enlarged gold nanoparticles (AuNPs). The reductive molecule such as H2O2 can act as the reductant to reduce HAuCl4, which will make the Au seeds grow. The enlarged AuNPs can effectively quench the fluorescence of UCNPs owing to the good spectral overlap between the absorption band of the AuNPs and the emission band of the UCNPs. Utilizing the FRET between the UCNPs and enlarged AuNPs, good linear relationship between the fluorescence of UCNPs and the concentration of H2O2 can be found. Based on this strategy, H2O2 related molecules such as l lactate, glucose, and uric acid can also be quantified. On the basis of UCNPs and PVP/HAuCl4, a general strategy for other reductants such as ascorbic acid (AA), dopamine (DA), or enzyme activity can be established. Therefore, the universal multifunctional nanoplatform based on UCNPs and the target-inducing in situ enlarged Au NPs will show its potential as a simple method for the detection of some life related reductive molecules, enzyme substrates, as well as enzyme activity. PMID- 29185339 TI - Ultrabright Fluorescent Silica Nanoparticles Embedded with Conjugated Oligomers and Their Application in Latent Fingerprint Detection. AB - Fluorescent micro- and nanosized particles have a broad range of applications in biology, medicine, and engineering. For these uses, the materials should have high emission efficiency and good photostability. However, many organic fluorophores suffer from aggregation-induced quenching effects and photobleaching. Here, we used a simple method based on covalently blending a fluorescent conjugated oligomer with silica nanoparticles to achieve emission quantum yields as high as 97%. The resulting system also showed excellent stability under continuous light illumination, in a range of pH values and temperatures, and in common solvents. This fluorescent material showed outstanding properties, including highly efficient blue emission, low cost, low toxicity, and easy synthesis. Furthermore, its effectiveness for latent fingerprint detection was demonstrated as a proof of concept on various substrates. The obtained emissive fingerprint powder gave good optical/fluorescent images with high contrast and resolution between the ridges and spaces. PMID- 29185340 TI - Effect of Fermentation pH on Protein Bioaccessibility of Soymilk Curd with Added Tea Polyphenols As Assessed by in Vitro Gastrointestinal Digestion. AB - The aim of this study was to compare the effect of fermentation pH on protein bioaccessibility of four soymilk curds enriched with tea polyphenols (TP). The curds were generated by fermentation with Weissella hellenica D1501 and the fermentation terminated at different pH values, namely at pH 5.7, 5.4, 5.1, and 4.8 (SMTP-5.7, SMTP-5.4, SMTP-5.1, SMTP-4.8). Particle-size distribution, soluble protein content, gel electrophoresis, and peptides content were monitored at oral, gastric, and intestinal levels. Results showed that SMTP-4.8 was the matrix most resistant to protein digestion in the gastric phase according to the soluble protein content. Similar particle size distribution and protein degradation patterns were observed for these curds in gastric and intestinal phase. However, there was a significant difference (P < 0.05) in the content of small peptides (<10 kDa) at the end of intestinal digestion among the four curds. Overall, terminating fermentation at pH 5.4-5.7 of soymilk curds enriched with TP is recommended. PMID- 29185341 TI - High-Performance Field Emission from a Carbonized Cork. AB - To broaden the range of application of electron beams, low-power field emitters are needed that are miniature and light. Here, we introduce carbonized cork as a material for field emitters. The light natural cork becomes a graphitic honeycomb upon carbonization, with the honeycomb cell walls 100-200 nm thick and the aspect ratio larger than 100, providing an ideal structure for the field electron emission. Compared to nanocarbon field emitters, the cork emitter produces a high current density and long-term stability with a low turn-on field. The nature of the cork material makes it quite simple to fabricate the emitter. Furthermore, any desired shape of the emitter tailored for the final application can easily be prepared for point, line, or planar emission. PMID- 29185342 TI - Comparative Proteomics of Enterotoxigenic Escherichia coli Reveals Differences in Surface Protein Production and Similarities in Metabolism. AB - Enterotoxigenic Escherichia coli (ETEC) infections are an important cause of diarrhea among young children living in low- and middle-income countries and visiting travelers. The development of effective vaccines is complicated by substantial genomic diversity that exists among ETEC isolates. To investigate how ETEC genomic variation is reflected at expressed proteome level, we applied label free quantitative proteomics to seven human ETEC strains representing five epidemiologically important lineages. We further determined the proteome profile of the nonpathogenic E. coli B strain BL21(DE3) to discriminate features specific for ETEC. The analysis yielded a data set of 2893 proteins, of which 1729 were present in all strains. Each ETEC strain produced on average 27 plasmid- or chromosomally-encoded proteins with known or putative connections to virulence, and a number of strain-specific proteins associated with the biosynthesis of surface antigens. Statistical comparison of protein levels between the ETEC strains and BL21(DE3) revealed several proteins with considerably increased levels only in BL21(DE3) including enzymes of arginine biosynthesis and metabolism of melibiose, galactitol, and gluconate. ETEC strains displayed consistently increased levels of proteins that were functional in iron acquisition, maltose metabolism, and acid resistance. The latter results suggest that specific metabolic functions might be shared among ETEC isolates. PMID- 29185343 TI - Pyrroloquinoline Quinone, a Redox-Active o-Quinone, Stimulates Mitochondrial Biogenesis by Activating the SIRT1/PGC-1alpha Signaling Pathway. AB - Pyrroloquinoline quinone (PQQ), a redox-active o-quinone found in various foods and mammalian tissues, has received an increasing amount of attention because of a number of health benefits that can be attributed to its ability to enhance mitochondrial biogenesis. However, its underlying molecular mechanism remains incompletely understood. We have now established that the exposure of mouse NIH/3T3 fibroblasts to a physiologically relevant concentration of PQQ significantly stimulates mitochondrial biogenesis. The exposure of NIH/3T3 cells to 10-100 nM PQQ for 48 h resulted in increased levels of Mitotracker staining, mitochondrial DNA content, and mitochondrially encoded cytochrome c oxidase subunit 1 (MTCO1) protein. Moreover, we observed that PQQ treatment induces deacetylation of the peroxisome proliferator-activated receptor-gamma-coactivator 1alpha (PGC-1alpha) and facilitates its nuclear translocation and target gene expression but does not affect its protein levels, implying increased activity of the NAD+-dependent protein deacetylase sirtuin 1 (SIRT1). Indeed, treatment with a SIRT1 selective inhibitor, EX-527, hampered the ability of PQQ to stimulate PGC 1alpha-mediated mitochondrial biogenesis. We also found that the PQQ treatment caused a concentration-dependent increase in the cellular NAD+ levels, but not the total NAD+ and NADH levels. Our results suggest that PQQ-inducible mitochondrial biogenesis can be attributed to activation of the SIRT1/PGC-1alpha signaling pathway by enhancing cellular NAD+ formation. PMID- 29185344 TI - Highly Efficient Deep-UV Light-Emitting Diodes Using AlN-Based Deep-UV Transparent Glass Electrodes. AB - Many studies have set out to develop electrodes that are both highly conductive and transparent across a wide spectral region, from visible to deep UV (DUV). However, few solutions have been proposed because these two properties are mutually exclusive. In this paper, an AlN-based glass electrode film with a conducting filament formed by the application of an ac pulse is proposed as a solution, which exhibits a high transmittance in the DUV region (over 95.6% at 280 nm) and a low contact resistance with a p-Al0.4Ga0.6N layer (rhoc = 3.2 * 10 2 Omega.cm2). The Ohmic conduction mechanism at the interface between the AlN film and the p-Al0.4Ga0.6N layers is fully examined using various analytical tools. This AlN film is finally applied to a 280 nm top-emitting light-emitting diode, to verify the validity of the method, which exhibits very stable operations with a forward voltage of 7.7 V at 20 mA, a light output power of 7.49 mW at 100 mA, and, most importantly, a record high external quantum efficiency of 2.8% after packaging. PMID- 29185345 TI - Evaluating LINE-1 methylation in cleft lip tissues and its association with early pregnancy exposures. AB - AIM: To pilot investigation of methylation of long interspersed nucleotide element-1 in lip tissues from infants with nonsyndromic cleft lip, and its association with maternal periconceptional exposures. METHODS: The lateral and medial sides of the cleft lips of 23 affected infants were analyzed for long interspersed nucleotide element-1 methylation by bisulfite conversion and pyrosequencing. RESULTS: The medial side showed 1.8% higher methylation compared with the lateral side; p = 0.031, particularly in male infants (2.7% difference; p = 0.011) or when the mothers did not take folic acid during periconceptional period (2.4% difference; p = 0.011). These results were not statistically significant when Bonferroni adjustment was used. CONCLUSION: The observed differences in DNA methylation, although nonsignificant after correction for multiple comparisons, suggest that differential regulation of the two sides may impact lip fusion and warrant larger-scale replication.

AB - Sigma-1 (sigma1) receptor has been identified as a chaperone protein that interacts with other proteins, such as N-methyl-D-aspartate (NMDA) and opioid receptors, modulating their activity. sigma1 receptor antagonists have been developed to obtain useful compounds for the treatment of psychoses, pain, drug abuse and cancer. Some interesting compounds such as E-5842 (5) and MS-377 (24), haloperidol and piperazine derivatives, respectively, were endowed with high affinity for sigma1 receptors (Ki sigma1 = 4 and 73 nM; Ki sigma2 = 220 and 6900, respectively). They were developed for the treatment of psychotic disorders and 5 also underwent Phase II clinical trials suggesting interesting potential therapeutic applications. Here, sigma1 receptor antagonists have been grouped based on chemical structure and reviewed according to structure-activity relationship and potential therapeutic role.

PMID- 29185347 TI - Hyperglycaemia and the SOAR stroke score in predicting mortality. AB - BACKGROUND: We assessed the association between admission blood glucose levels and acute stroke mortality and examined whether there was any incremental value of adding glucose status to the validated acute stroke mortality predictor - the SOAR (stroke subtype, Oxford Community Stroke Project classification, age, and pre-stroke modified Rankin) score. METHODS: Data from Norfolk and Norwich University Hospital stroke and Transient Ischaemic Attack register (2003-2013) and Anglia Stroke Clinical Network Evaluation Study (2009-2012) were analysed. Multivariable logistic regression analysis assessed the association between admission blood glucose levels with inpatient and 7-day mortality. The prognostic ability of the SOAR score was then compared with the SOAR with glucose score. RESULTS: A total of 5575 acute stroke patients (ischaemic stroke: 89.2%) with mean age (standard deviation) of 76.97 ( +/- 11.88 ) years were included. Both borderline hyperglycaemia (7.9-11.0 mmol/L) and hyperglycaemia (>11.0 mmol/L) when compared to normoglycaemia (4.0-7.8 mmol/L) were associated with both 7-day and inpatient mortality after controlling for sex, age, Oxford Community Stroke Project classification and pre-stroke modified Rankin score. Both the SOAR stroke score and SOAR-G score were good predictors of inpatient stroke mortality [area under the curve: 0.82 (95% confidence interval: 0.81-0.84) and 0.83 (95% confidence interval: 0.81-0.84)], respectively. These scores were also good at predicting outcomes in both patients with and without diabetes. CONCLUSION: High blood glucose levels at admission were associated with worse acute stroke mortality outcomes. The constituents of the SOAR stroke score were good at predicting mortality after stroke. PMID- 29185349 TI - Adipose tissue macrophage polarization in cardiovascular disease. PMID- 29185350 TI - Arthroscopic Resection of Dorsal Wrist Ganglion: Results and Rate of Recurrence Over a Minimum Follow-up of 4 Years. AB - BACKGROUND: Dorsal wrist ganglia are the most common soft tissue tumor type of the upper limb. Surgical resection, open or arthroscopic, is one of the most frequent procedures performed by hand surgeons. This study sought to perform an objective evaluation of the outcomes of arthroscopic resection of dorsal wrist ganglia and their recurrence rates over 4 years. Patients treated with arthroscopic resection were expected to have favorable outcomes and low complication rates after 4 years of follow-up. METHODS: We evaluated 34 cases of dorsal wrist ganglia in patients who underwent arthroscopic resection. The patients were evaluated using the Quick-Disabilities of the Arm, Shoulder and Hand (QuickDASH) outcome measure, visual analog scale (VAS) for pain, range of motion of the wrist, palmar grip strength, rates of recurrence, and complications. RESULTS: During the postoperative period, the QuickDASH score averaged 2.3 points, the mean residual pain by VAS was 0.54, full range of wrist movement was recovered by all patients, and the mean palmar grip strength was 29.4 kgf; there was 1 case with recurrence. There were no severe postoperative complications throughout the follow-up period. CONCLUSIONS: The outcomes, recurrence, and complications rates after 4 years of follow-up presented in this study support the use of arthroscopy as a treatment for dorsal wrist ganglion. PMID- 29185351 TI - Irreducible Galeazzi Fracture-Dislocations. AB - BACKGROUND: Fractures of the radial shaft with disruption of the distal radial ulnar joint (DRUJ) or Galeazzi fractures are treated with reduction of the radius followed by stability assessment of the DRUJ. In rare instances, the reduction of the DRUJ is blocked by interposed structures requiring open reduction of this joint. The purpose of this study is to review all cases of irreducible Galeazzi fracture-dislocations reported in the literature to offer guidelines in the diagnosis and management of this rare injury. METHODS: A search of the MEDLINE database, OVID database, and PubMed database was employed using the terms "Galeazzi" and "fracture." Of the 124 articles the search produced, a total of 12 articles and 17 cases of irreducible Galeazzi fracture-dislocations were found. RESULTS: The age range was 16 to 64 years (mean = 25 years). A high-energy mechanism of injury was the root cause in all cases. More than half of the irreducible DRUJ dislocations were not identified intraoperatively. In a dorsally dislocated DRUJ, a block to reduction in most cases (92.3%) was secondary to entrapment of one or more extensor tendons including the extensor carpi ulnaris, extensor digiti minimi, and extensor digitorum communis, with the remaining cases blocked by fracture fragments. Irreducible volar dislocations due to entrapment of the ulnar head occurred in 17.6% of cases with no tendon entrapment noted. CONCLUSIONS: In the presence of a Galeazzi fracture, a reduced/stable DRUJ needs to be critically assessed as more than half of irreducible DRUJs in a Galeazzi fracture-dislocation were missed either pre- or intraoperatively. PMID- 29185352 TI - Psychological distress and unmet mental health needs among urban taxi drivers: A cross-sectional survey. AB - OBJECTIVES: The taxi industry relies on a male-dominated, predominately immigrant workforce who face multiple risk factors for poor mental health including shift work, low pay and threats of violence. Despite these risk factors, no previous study has documented the prevalence of psychological distress in the taxi industry. We investigated psychological distress among urban taxi drivers and explored the factors associated with high levels of distress. METHOD: A total of 380 taxi drivers were surveyed at the Melbourne Airport holding yard between September 2016 and March 2017. Psychological distress was measured using the K10. Logistic regression models were used to estimate the association between high levels of psychological distress and migration, work patterns, potentially traumatic events, health care use and social connectedness. RESULTS: A third (33%) of drivers had very high (K10 ? 30) levels of distress and 28% had high (K10 = 22-29) levels of distress. Trauma was significantly associated with high levels of psychological distress, and rates of trauma were much higher among drivers than among the Australian population. Despite high levels of distress, drivers were no more likely than other Australian men to visit a health professional. CONCLUSION: Urban taxi drivers are at very high risk for mental health problems, yet the mental health needs of this largely immigrant workforce has gone largely unnoticed. Interventions tailored to the unique characteristics of the job and the demographic composition of the workforce are urgently needed. PMID- 29185353 TI - Facile synthesis of some pyrazoline-based compounds with promising anti inflammatory activity. AB - AIM: Search for new anti-inflammatory agents with higher efficacy and lower toxicity is an urgent demand in drug discovery era. METHODOLOGY: Different pyrazoline derivatives 4a,b, 5a,b, 6a-h and 7a-f were prepared from the condensation reactions of 1,5-bis(5-methylfuran/thiophen-2-yl)penta-1,4-dien-3 ones 3a,b with different hydrazine derivatives. All compounds were screened for their anti-inflammatory activity using the carrageenan-induced paw edema method in rats and TNF-alpha inhibition assay. RESULTS: Many compounds revealed promising anti-inflammatory activity relative to indomethacin especially compounds 4a, 5a, 5b, 6b, 6d, 6f and 7b. They were safe to the gastric mucosa and did not cause toxicity up to tenfolds the anti-inflammatory dose, in addition, all compounds inhibited TNF-alpha with IC50 values of 1.7-100 nM. PMID- 29185354 TI - Validation and Psychometric Properties of the German Version of the Delirium Motor Subtype Scale (DMSS). AB - OBJECTIVE: Delirium has been characterized into its subtypes-hypoactive, hyperactive, mixed, or no motor subtype-along with the use of the Delirium Motor Symptom Scale (DMSS). The German version of this scale (DMSS-G), however, has not yet been validated. METHOD: We determined internal consistency, reliability, and validity of the DMSS-G in the surgical intensive care unit, using DSM-IV-TR criteria and the Delirium Rating Scale-Revised-98. RESULTS: In total, 289 patients were included, and out of these, 122 were delirious. The DMSS-G showed excellent internal consistency (Cronbach's alpha = 0.92) and interrater reliability (Fleiss kappa = 0.83). Additionally, the overall concurrent validity was substantial (Cramer's V = 0.69); within subtypes, hyperactive, hypoactive, or mixed, the concurrent validity remained at least substantial (Cohen's kappa = 0.73-0.82) and the sensitivity ranged from 60% to 97%. In contrast, in those with no motor subtype, we found the concurrent validity (Cohen's kappa = 0.31) and sensitivity to be low (22%). Overall, specificity for all individual subtypes was high (82% to 100%). The DMSS was very sensitive in both rating hyperactive and hypoactive motor symptoms of delirium. CONCLUSION: The DMSS-G is a highly reliable and valid instrument for detecting motor symptoms in delirium, which provides an accurate instrument to classify the motor subtypes of delirium. PMID- 29185355 TI - The Effect of Human Adipose Tissue-Derived Mesenchymal Stem Cells in Rat's Subglottic Stenosis Model. AB - OBJECTIVE: Subglottic stenosis remains a clinical challenge. The aim of this study was to evaluate the effect of human adipose tissue-derived mesenchymal stem cells (hAMSCs) in rat model of subglottic stenosis. SUBJECTS AND METHODS: Ninety six 13-week-old male rats were enrolled in this study. They were divided into 3 groups as normal control (NC) group, a subglottic injury and media injection (SM) group, and a subglottic injury and media-stem cell injection (SMSC) group. The hAMSCs were immediately injected into subglottis after injury. Histologic characteristics of subglottis; the mRNA expressions of interleukin-1beta, cyclooxygenase-2, tumor growth factor-beta and basic fibroblast growth factor; and hAMSCs' survival were evaluated. RESULTS: The hAMSCs survived in the subglottis of the rat until 10 days after implantation. The NC and SMSC groups had a significantly wider subglottic lumen and thinner lamina propria than the SM group at 56 days after injury. Collagen intensity of subglottis was significantly higher in the SM group than in the NC and SMSC groups at 28 days after injury. Gene expression didn't show significant difference between the SM group and the SMSC group. CONCLUSIONS: The hAMSCs injection was found to be helpful for preventing subglottic stenosis in a rat model. PMID- 29185356 TI - A profile of social, separation and generalized anxiety disorders in an Australian nationally representative sample of children and adolescents: Prevalence, comorbidity and correlates. AB - OBJECTIVE: To examine (1) the 12-month prevalence of social anxiety disorder (SOC), separation anxiety disorder (SEP) and generalized anxiety disorder (GAD) in a large, nationally representative sample of Australian youth; (2) patterns of comorbidity between these disorders; (3) demographic and socio-environmental correlates and (4) the psychosocial impact and service use associated with each condition. METHOD: Data are from the 2013/2014 Australian national, face-to-face household Young Minds Matter survey of mental health and wellbeing. Informants were parents or carers reporting on 6310, 4- to 17-year-olds (55% of eligible households). The presence of each of the three anxiety disorders was determined based on the Diagnostic Interview Schedule for Children-Version IV. RESULTS: In the past 12 months, 6.6% of youth had experienced at least one of SOC, SEP or GAD, with rates of 2.3% for SOC, 4.3% for SEP and 2.3% for GAD. Rates did not differ by gender but were significantly higher for SOC and GAD and lower for SEP in 12- to 17-year-olds than 4- to 11-year-olds. Comorbidity between these disorders was high, although lower for SEP. Having SOC, SEP or GAD was associated with not living with both biological parents, having a parent with a mental health problem, elevated negative family events, low carer employment and peer victimization. The association with family risk factors was greater for SEP than for SOC and GAD. Although the majority of anxious youth had received professional help, this was less likely in the younger cohort. CONCLUSION: Social, separation and generalized anxiety disorders in young people are relatively common and impairing, with a high level of comorbidity. There are both commonalities and differences in socio-environmental correlates. The majority of anxious youth received some form of professional assistance, although the rate was lower among children compared to adolescents. PMID- 29185357 TI - When Old Habits Train a New Generation: Findings From a National Survey of Internal Medicine Program Directors on Procedural Training. AB - Resident physicians routinely perform bedside procedures that pose substantial risk to patients. However, no standard programmatic approach to supervision and procedural competency assessment among residents currently exists. The authors performed a national survey of internal medicine (IM) program directors to examine procedural assessment and supervision practices of IM residency programs. Procedures chosen were those commonly performed by medicine residents at the bedside. Of the 368 IM programs, 226 (61%) completed the survey. Programs reported the predominant method of training as 171 (74%) apprenticeship and 106 (46%) as module based. The majority of programs used direct observation to attest to competence, with 55% to 62% relying on credentialed residents. Most programs also relied on a minimum number of procedures to determine competence (64%-88%), 72% of which reported 5 procedures (a lapsed historical standard). This national survey demonstrates that procedural assessment practices for IM residents are insufficiently robust and may put patients at undue risk. PMID- 29185358 TI - Simplified Summative Temporal Bone Dissection Scale Demonstrates Equivalence to Existing Measures. AB - INTRODUCTION: Emphasis on patient safety has created the need for quality assessment of fundamental surgical skills. Existing temporal bone rating scales are laborious, subject to evaluator fatigue, and contain inconsistencies when conferring points. To address these deficiencies, a novel binary assessment tool was designed and validated against a well-established rating scale. METHODS: Residents completed a mastoidectomy with posterior tympanotomy on identical 3D printed temporal bone models. Four neurotologists evaluated each specimen using a validated scale (Welling) and a newly developed "CanadaWest" scale, with scoring repeated after a 4-week interval. RESULTS: Nineteen participants were clustered into junior, intermediate, and senior cohorts. An ANOVA found significant differences between performance of the junior-intermediate and junior-senior cohorts for both Welling and CanadaWest scales ( P < .05). Neither scale found a significant difference between intermediate-senior resident performance ( P > .05). Cohen's kappa found strong intrarater reliability (0.711) with a high degree of interrater reliability of (0.858) for the CanadaWest scale, similar to scores on the Welling scale of (0.713) and (0.917), respectively. CONCLUSION: The CanadaWest scale was facile and delineated performance by experience level with strong intrarater reliability. Comparable to the validated Welling Scale, it distinguished junior from senior trainees but was challenged in differentiating intermediate and senior trainee performance.

AB - Stroke is a disease of the leading causes of mortality and disability across the world, but the benefits of drugs curative effects look less compelling, intracellular calcium overload is considered to be a key pathologic factor for ischemic stroke. Gualou Guizhi decoction (GLGZD), a classical Chinese medicine compound prescription, it has been used to human clinical therapy of sequela of cerebral ischemia stroke for 10 years. This work investigated the GLGZD improved prescription against intracellular calcium overload could decreased the concentration of [Ca2+]i in cortex and striatum neurone of MCAO rats. GLGZD contains Trichosanthin and various small molecular that they are the potential active ingredients directed against NR2A, NR2B, FKBP12 and Calnodulin target proteins/enzyme have been screened by computer simulation. "Multicomponent systems" is capable to create pharmacological superposition effects. The Chinese medicine compound prescriptions could be considered as promising sources of candidates for discovery new agents. PMID- 29185360 TI - Role of metformin on base excision repair pathway in p53 wild-type H2009 and HepG2 cancer cells. AB - The antidiabetic agent metformin was shown to further possess chemopreventive and chemotherapeutic effects against cancer. Despite the advances, the underlying molecular mechanisms involved in decreasing tumor formation are still unclear. The understanding of the participation of oxidative stress in the action mechanism of metformin and its related effects on p53 and on DNA base excision repair (BER) system can help us to get closer to solve metformin puzzle in cancer. We investigated the effects of metformin in HepG2 and H2009 cells, verifying cytotoxicity, oxidative stress, antioxidant status, and DNA BER system. Our results showed metformin induced oxidative stress and reduced antioxidant capacity. Also, metformin treatment with hydrogen peroxide (H2O2) enhanced these effects. Although DNA BER enzyme activities were not changed accordantly together by metformin as a single agent or in combination with H2O2, activated p53 was decreased with increased oxidative stress in H2009 cells. Our study on the relationship between metformin/reactive oxygen species and DNA BER system in cancer cells would be helpful to understand the anticancer effects of metformin through cellular signal transduction pathways. These findings can be a model of the changes on oxidative stress that reflects p53's regulatory role on DNA repair systems in cancer for the future studies. PMID- 29185361 TI - Melatonin concentration in follicular fluid is correlated with antral follicle count (AFC) and in vitro fertilization (IVF) outcomes in women undergoing assisted reproductive technology (ART) procedures. AB - The aim of the present study was to evaluate the possible relationship between melatonin levels in the follicular fluid (FF) and in vitro fertilization (IVF) outcomes in women undergoing assisted reproductive treatment. Sixty-three females (20 to 40 years old) scheduled for IVF were divided into three groups based on their antral follicle count (AFC). We determined FF melatonin concentrations in group A (AFC?6, n = 21), group B (7?AFC?14, n = 22), group C (AFC?15, n = 20) on oocyte retrieval day. Patients in group C had significantly higher melatonin levels as compared to patients in groups A and B (p < .001). Melatonin levels of the patients were significantly positively correlated with antral follicle count (AFC, p < .001), serum anti-Mullerian hormone(AMH) levels (p =.001), serum estradiol (E2) levels on human chorionic gonadotropin (HCG) administration day (p = .001), total follicle-stimulating hormone (FSH) dose (p = .002), starting FSH dose (p = .035), number of retrieved oocytes (p < .001), total fertilized oocytes (p < .001), normally fertilized oocytes (p < .001), cleaved oocytes (p < .001), number of high-quality day 3 embryos (p = .004), blastocysts obtained (p = .007) and total embryos obtained (day3 embryos + day5/6 blastocysts) (p = .005). The levels were significantly negatively correlated with age (p < .001), basal serum FSH levels (p = .003), serum FSH (p = .001) and serum luteinizing hormone (LH) levels (p = .003) on HCG administration day. This is the first demonstration of a significant positive correlation of melatonin concentrations with AFC in patients undergoing IVF. We propose that FF melatonin levels may influence the IVF outcomes. PMID- 29185362 TI - Living with incurable cancer: what are the rehabilitation needs in a palliative setting? AB - BACKGROUND: Increasing numbers of people are living with incurable cancers. Symptoms, side effects, and treatment burdens impact on physical functioning, yet little is known about the impact on people's lives and how best to provide rehabilitation. MATERIALS AND METHODS: A qualitative study employing a phenomenological approach explored the lived experience of incurable cancer. A purposive sample of six people participated in semi-structured interviews. The data were analysed thematically at a semantic level to identify the functional difficulties experienced by people living with incurable cancer, the meanings of those difficulties, and participants perceived rehabilitation needs. RESULTS: People living with incurable cancer described cancer-related issues spanning all five domains of the International Classification of Functioning, Disability and Health (ICF). Although highly valued amongst study participants, rehabilitation services were difficult to access, poorly utilised, and referrals were sporadic and consequential; indicative of poor awareness of rehabilitation for people with incurable cancer amongst potential referrers. DISCUSSION: Participants valued a change in terminology away from "palliative" towards more positive language in line with enhanced supportive care movements. Validated tools such as the Palliative Care Therapy Outcome Measure, which align with the ICF, would allow rehabilitation professionals to demonstrate maintenance or improvement in participation and wellbeing. Implications for Rehabilitation Incurable cancer leads to a fluctuating multifactorial disability. People living with incurable cancer can benefit from rehabilitation input throughout their illness. Offering flexible and varied rehabilitation options for people living with incurable cancer will increase physical and emotional well-being, function, and coping. Allied health professionals should take and create opportunities to promote rehabilitation for people living with incurable cancer and their services to other potentially referring healthcare professionals to increase understanding of benefits and utilisation of available services for people living with incurable cancer. PMID- 29185363 TI - Do Hispanic Girls Develop Eating Disorders? A Critical Review of the Literature. AB - INTRODUCTION: Eating disorders have become increasingly prevalent in North America. Anorexia nervosa, bulimia nervosa, and binge eating disorder were previously thought to solely affect Caucasian women. However, contemporary research has studied the occurrence of this phenomenon in ethnic minority women, such as Latinas. METHODS: This article presents a critical review of 12 quantitative, prospective psychological research studies from the past 17 years. RESULTS: The authors in the reviewed literature identified bodily dissatisfaction, environmental influences, and acculturation as significant risk factors in the development of eating disorders in Hispanic girls and women. CONCLUSION: The methodology and empirical findings from these studies are discussed, and suggestions for future research and culturally sensitive clinical treatment are considered. PMID- 29185364 TI - The effect of oxidative stress on the progression of Hashimoto's thyroiditis. AB - OBJECTIVE: We aimed to investigate the effects of oxidative stress in the pathogenesis and progression of Hashimoto's thyroiditis (HT). METHODS: Forty euthyroid and 40 subclinical hypothyroid patients older than 18 years and not yet had received treatment were enrolled in the study. RESULTS: In the 9 months follow-up, 14 of the HT patients developed overt hypothyroidism. The mean total oxidant status (TOS) and oxidative stress index (OSI) were higher in patients who developed overt hypothyroidism than those who did not (p < .001). And no significant difference was found between the two groups in terms of paraoxanase-1 and arylesterase (p > .05). Multivariable Cox regression model showed thyroid stimulating hormone level (HR = 1.348, p < .001), free-thyroxine level (HR = 0.481, p = .017) and OSI ratio (HR = 2.349, p < .001) to be independent predictors of development of overt hypothyroidism. OSI level, being over 2.96 with 92.9% sensitivity and 62.5% specificity, predicts the risk of hypothyroidism. CONCLUSION: Oxidative stress may be an effective risk factor in the development of overt hypothyroidism in HT. PMID- 29185365 TI - Synthesis and antitumor activity of novel 2, 3-didithiocarbamate substituted naphthoquinones as inhibitors of pyruvate kinase M2 isoform. AB - The M2 isoform of pyruvate kinase (PKM2) is a potential antitumor therapeutic target. In this study, we designed and synthesised a series of 2, 3 didithiocarbamate substituted naphthoquinones as PKM2 inhibitors based on the lead compound 3k that we previously reported. Among them, compound 3f (IC50 = 1.05 +/- 0.17 uM) and 3h (IC50 = 0.96 +/- 0.18 uM) exhibited potent inhibition of PKM2, and their inhibitory activities are superior to compound 3k (IC50 = 2.95 +/ 0.53 uM) and the known PKM2 inhibitor shikonin (IC50 = 8.82 +/- 2.62 uM). In addition, we evaluated in vitro antiproliferative effects of target compounds using MTS assay. Most target compounds exhibited dose-dependent cytotoxicity with IC50 values in nanomolar concentrations against HCT116, MCF7, Hela, H1299 and B16 cells. These small molecule PKM2 inhibitors not only provide candidate compounds for cancer therapy, but also offer a tool to probe the biological effects of PKM2 inhibition on cancer cells. PMID- 29185366 TI - The Dutch version of the self-report Child Activity and Limitations Interview in adolescents with chronic pain. AB - PURPOSE: To assess the factor structure, related constructs and internal consistency of the Child Activity Limitation Interview 21-Child version for use in Dutch-language countries. METHODS: Cross-sectional validation study: After forward and back translation of the Dutch version of the Child Activity Limitation Interview 21-Child adolescents (11-21 years old) with chronic musculoskeletal pain completed an assessment. The assessment contained the Dutch Child Activity Limitation Interview, and questionnaires about demographics, pain intensity, functional disability, anxiety and depression. Internal consistency and construct validity were evaluated through exploratory factor analysis (principal axis factoring with oblique rotation) and hypotheses testing using pain intensity, activity limitations, anxiety and depression as comparative constructs. RESULTS: Seventy-four adolescents completed the assessment. Exploratory factor analysis resulted in a two-factor structure, explaining 50% of the variance. Internal consistency was good (Cronbach's alpha = 0.91 total scale, alpha = 0.90 Factor 1, alpha = 0.80 Factor 2). All nine hypotheses were confirmed. CONCLUSION: The Dutch version can be used to assess pain-related disability in Dutch-speaking adolescents comparable to the study sample. Scores on both subscales provide insight into the severity of the pain-related disability in both daily routine and more physically vigorous activities. Implications for Rehabilitation Chronic pain is a disabling disorder which not only impacts physically but restricts quality of life. This study provides clinicians a questionnaire to measure pain-related disability and quantify the impact of pain on the daily living of adolescents. The advantage of the Dutch version of the Child Activity and Limitations Interview over other measurements is that it can distinguish limitations in daily activities from more physically vigorous activities. PMID- 29185367 TI - Aiming to Deceive: Examining the Role of the Quiet Eye During Deceptive Aiming Actions. AB - In three experiments, we explored the use of deceptive gaze in soccer penalty takers using eye-tracking equipment. In Experiment 1, players competed against a goalkeeper while taking unconstrained shots. Results indicated that when players used deception (looking to the opposite side to which they shot), they extended the duration of their final aiming (quiet eye) fixation and maintained shooting accuracy. In Experiment 2, with no goalkeeper present, players still used extended quiet-eye durations when using a deceptive strategy, but this time, their accuracy suffered. In Experiment 3, we manipulated the goalkeeper's location while controlling for the use of peripheral vision and memory of goal size. Results indicated that increased quiet-eye durations were required when using deceptive aiming, and that accuracy was influenced by the position of the goalkeeper. We conclude that during deceptive aiming, soccer players maintain accuracy by covertly processing information related to the goalkeeper's location. PMID- 29185368 TI - The Digest. PMID- 29185369 TI - Cellular effects of thirdhand tobacco smoke from smokers' homes. AB - After the cigarette is extinguished, many toxic compounds remain in the environment and accumulate in the air or on surfaces. This exposure is termed thirdhand smoke (THS) and its risks are poorly known. The aim of the study was to evaluate the cellular effects of THS from smokers' homes. Papers were placed in nine smoker's home and three nonsmoker's homes. An area equivalent to the paper size was cleaned with a cotton wipe. A549, Hep-2 and 3T3 cells were exposed to THS for 24 h and cellular functions were assessed by MTT, neutral red (NR) reuptake and trypan blue exclusion assays. High levels of nicotine were found in samples from smokers' homes. Cellular proliferation was similar in almost all samples after THS exposure. Few changes in the cellular functions were observed, mainly higher mitochondrial activity, in paper samples. We are able to detect markers of THS collected from smokers' homes, but a clear evidence of cellular toxicity cannot be demonstrated by the present assays. This is the first study to evaluate the cellular effects of THS samples collected from smokers' homes. PMID- 29185370 TI - Effect of nicotine on placental ischemia-induced complement activation and hypertension in the rat. AB - Preeclampsia is a pregnancy-specific condition manifested by new-onset maternal hypertension with systemic inflammation, including increased innate immune system complement activation. While exact pathophysiology is unknown, evidence suggests that inadequate spiral artery invasion and resulting utero-placental insufficiency is the initiating event. Cigarette smoking during pregnancy decreases the risk of preeclampsia. Nicotine, a major component of cigarettes, stimulates the efferent cholinergic anti-inflammatory pathway through peripherally expressed nicotinic acetylcholine receptors (nAChR) and is known to attenuate ischemia-reperfusion injury in kidney and liver. Prior studies indicated that complement activation was critical for placental ischemia-induced hypertension in a rat model. Thus, it was hypothesized here that nicotine was responsible for the protective effect of cigarette smoking in preeclampsia and would attenuate placental ischemia-induced systemic complement activation and hypertension. The Reduced Utero-placental Perfusion Pressure (RUPP) model in the pregnant rat was employed to induce placental ischemia, resulting in complement activation, fetal resorptions, and hypertension. On gestation day (GD)14, nicotine (1 mg/kg) or saline was administered via subcutaneous injection prior to RUPP surgery and daily through GD18. On GD19, placental ischemia significantly increased mean arterial pressure (MAP) in saline injected animals. However, the placental ischemia-induced increase in blood pressure was not evident in nicotine treated animals and nicotine treatment significantly increased MAP variability. Circulating C3a was measured as an indicator of complement activation and increased C3a in RUPP compared to Sham persisted with nicotine treatment, as did fetal resorptions. These data suggested to us that nicotine may contribute to the decreased risk of preeclampsia with cigarette smoking, but this protective effect was confounded by additional effects of nicotine on the cardiovascular system. PMID- 29185371 TI - Recent advances in longitudinal structural neuroimaging of younger-onset dementias. PMID- 29185372 TI - Recent advances in the microbiological diagnosis of bloodstream infections. AB - Rapid identification (ID) and antimicrobial susceptibility testing (AST) of the causative agent(s) of bloodstream infections (BSIs) are essential for the prompt administration of an effective antimicrobial therapy, which can result in clinical and financial benefits. Immediately after blood sampling, empirical antimicrobial therapy, chosen on clinical and epidemiological data, is administered. When ID and AST results are available, the clinician decides whether to continue or streamline the antimicrobial therapy, based on the results of the in vitro antimicrobial susceptibility profile of the pathogen. The aim of the present study is to review and discuss the experimental data, advantages, and drawbacks of recently developed technological advances of culture-based and molecular methods for the diagnosis of BSI (including mass spectrometry, magnetic resonance, PCR-based methods, direct inoculation methods, and peptide nucleic acid fluorescence in situ hybridization), the understanding of which could provide new perspectives to improve and fasten the diagnosis and treatment of septic patients. Although blood culture remains the gold standard to diagnose BSIs, newly developed methods can significantly shorten the turnaround time of reliable microbial ID and AST, thus substantially improving the diagnostic yield.

AB - OBJECTIVE: The aim of the study is to investigate the feasibility of a family based mindfulness intervention in improving children with inattention and hyperactivity symptoms. METHOD: A total of 100 children aged 5 to 7 years with ADHD symptoms and their parents were randomly assigned to a family-based mindfulness intervention ( n = 50) or a wait-list control group ( n = 50). RESULTS: Families from intervention group had greater improvements in children's ADHD symptoms, with medium effect sizes of -0.60 for inattention and -0.59 for hyperactivity; overall behaviors; and parenting stress and well-being than those in wait-list control group. CONCLUSION: The positive results on the child primary outcome measures have provided initial evidence of the family-based mindfulness intervention as a treatment option to ADHD. The reduction of parental stress and increase in psychological well-being has demonstrated the value of mindfulness in enhancing parent's self-management. PMID- 29185376 TI - Effect of the additional first ray osteotomy on hindfoot alignment after calcaneal osteotomy for the correction of mild-to-moderate adult type pes plano valgus. AB - PURPOSE: To determine the effect of the additional first ray osteotomy on hindfoot alignment for the correction of pes plano-valgus. METHODS: Data obtained from 37 consecutive patients recruited from 2006 to 2014 who underwent medial displacement calcaneal osteotomy (MDCO) alone (group H) or MDCO followed by medial cuneiform opening wedge osteotomy (MCOWO) (group HF) with a minimum 1-year follow-up were reviewed retrospectively. The mean follow-up periods were 34 and 32 months. RESULTS: Degree of decrease of Talonavicular coverage angle (TNCA) via surgery or postoperative TNCA on standing foot AP radiographs were not significantly different between group H and HF ( p = 0.287). The calcaneal pitch angle and medial cuneiform height on the standing foot lateral radiographs was significantly increased after operation in group HF ( p = 0.01), there was a significant difference with group H as well ( p = 0.033). In group HF, the Meary's angle was significantly decreased after operation, a significant difference compared to group H ( p = 0.009). Hindfoot alignment angle on the hindfoot alignment view was decreased after operation in both groups but was not significantly different between both groups ( p = 0.410). Hindfoot alignment ratio was also increased after the operation in both groups, but was not different between two groups ( p = 0.783). CONCLUSION: The additional first ray osteotomy using MCOWO had no correctional power for hindfoot correction, although it caused improvement in some radiographic parameters. PMID- 29185377 TI - The painter from Sinaloa: artistic analysis of a case of spatial agnosia and neglect of visual shapes. AB - Paintings produced spontaneously by patients with neurological lesions represent a fascinating opportunity to analyze some aspects of the underlying disease and involved brain mechanisms. Many cases of artists who have suffered spatial neglect following a neurological disease have been reported in the literature. However, only a few studies evaluating the different subtypes of graphic neglect and aspects related to the construction of perspective (three dimensionality) in works of art have been published. In the present article, we present the case of an artist who, after resection of a central neurocytoma that affected the right thalamo-parietal connections, suffered an impairment of the ability to create perspective in his paintings and involuntary omission of only shapes in the left side of his paintings, although colors and contours were preserved. PMID- 29185378 TI - Matching Microsimulation Risk Factor Correlations to Cross-sectional Data: The Shortest Distance Method. AB - BACKGROUND: Microsimulation models often compute the distribution of a simulated cohort's risk factors and medical outcomes over time using repeated waves of cross-sectional data. We sought to develop a strategy to simulate how risk factor values remain correlated over time within individuals, and compare it to available alternative methods. METHODS: We developed a method using shortest distance matching for modeling changes in risk factors in individuals over time, which preserves both the cohort distribution of each risk factor as well as the cross-sectional correlation between risk factors observed in repeated cross sectional data. We compared the performance of the method with rank stability and regression methods, using both synthetic data and data from the Framingham Offspring Heart Study (FOHS) to simulate a cohort's atherosclerotic cardiovascular disease (ASCVD) risk. RESULTS: The correlation between risk factors was better preserved using the shortest distance method than with rank stability or regression (root mean squared difference = 0.077 with shortest distance, v. 0.126 with rank stability and 0.146 with regression in FOHS, and 0.052, 0.426 and 0.352, respectively, in the synthetic data). The shortest distance method generated population ASCVD risk estimate distributions indistinguishable from the true distribution in over 99.8% of cases (Kolmogorov Smirnov, P > 0.05), outperforming some existing regression methods, which produced ASCVD distributions statistically distinguishable from the true one at the 5% level around 15% of the time. LIMITATIONS: None of the methods considered could predict individual longitudinal trends without error. The shortest-distance method was not statistically inferior to rank stability or regression methods for predicting individual risk factor values over time in the FOHS. CONCLUSIONS: A shortest distance method may assist in preserving risk factor correlations in microsimulations informed by cross-sectional data. PMID- 29185379 TI - Surgical dislocation of the hip without trochanteric osteotomy. AB - BACKGROUND: Surgical dislocation of the hip remains an important alternative in hip preservation surgery, especially when a dynamic access to the hip is needed and arthroscopy is not a suitable option. We describe a novel technique for operative dislocation of the hip without trochanteric osteotomy and the clinical results of our patients. METHODS: Surgical dislocation of the hip without trochanteric osteotomy was done through a modified lateral approach in all of the cases. A review of demographic, clinical, and radiological data was done in all of the patients operated with this technique between 2010 and 2015. Complications, walking aids, weight-bearing status, and modified Harris Hip Score (mHHS) were also recorded. RESULTS: Six surgical dislocations of the hip were carried out. Indications were tumor resection in five and bulletectomy in one hip. There were two women (four hips) and two men. Mean age was 19 +/- 3.8 years. Median follow-up was 2.5 years (range 2-4.5 years). Median mHHS was 92 (90-96). There were no intraoperative nor postoperative complications. CONCLUSIONS: Surgical dislocation of the hip without trochanteric osteotomy through a modified lateral approach appears to be a safe, simpler, and effective alternative. PMID- 29185381 TI - Long-term spatial clustering in free recall. AB - We explored the influence of space on the organisation of items in long-term memory. In two experiments, we asked our participants to explore a virtual environment and memorise discrete items presented at specific locations. Memory for those items was later on tested in immediate (T1) and 24 hours delayed (T2) free recall tests, in which subjects were asked to recall as many items as possible in any order. In experiment 2, we further examined the contribution of active and passive navigation in recollection dynamics. Results across experiments revealed a significant tendency for participants to consecutively recall items that were encountered in proximate locations during learning. Moreover, the degree of spatial organisation and the total number of items recalled were positively correlated in the immediate and the delayed tests. Results from experiment 2 indicated that the spatial clustering of items was independent of navigation types. Our results highlight the long-term stability of spatial clustering effects and their correlation with recall performance, complementing previous results collected in immediate or briefly delayed tests. PMID- 29185380 TI - 'We don't even have Wi-Fi': a descriptive study exploring current use and availability of communication technologies in residential aged care. AB - BACKGROUND: There has been significant growth in communication technologies. However, it is unknown to what extent RACFs accommodate such technologies. AIM: To explore the use and availability of communication technologies for use by residents within RACFs in Queensland, Australia. METHODS: A descriptive, structured telephone survey. Every 10th alphabetically listed facility from a total sample of n = 462 were telephoned and staff were invited to complete the survey. RESULTS: Forty-one out of a total of 93 RACFs completed the survey. The telephone was by far the primary form of communication used by residents to communicate with family and friends (n = 40; 97.6%). Conversely, the use of web connection communication software (Skype or similar) was uncommon. CONCLUSION: The use and availability of communication technologies is limited within RACFs, highlighting a significant lag in the uptake within the sector. PMID- 29185383 TI - Prediction of height increment using preoperative radiological parameters following selective thoracic fusion with alternate-level pedicle screw construct in Lenke 1 and 2 adolescent idiopathic scoliosis patients. AB - PURPOSE: This study aims to derive a formula to predict post-operative height increment in Lenke 1 and Lenke 2 adolescent idiopathic scoliosis (AIS) patients using preoperative radiological parameters. METHODS: This study involved 70 consecutive Lenke 1 and 2 AIS patients who underwent scoliosis correction with alternate-level pedicle screw instrumentation. Preoperative parameters that were measured included main thoracic (MT) Cobb angle, proximal thoracic (PT) Cobb angle, lumbar Cobb angle as well as thoracic kyphosis. Side-bending flexibility (SBF) and fulcrum-bending flexibility (FBF) were derived from the measurements. Preoperative height and post-operative height increment was measured by an independent observer using a standardized method. RESULTS: MT Cobb angle and FB Cobb angle were significant predictors ( p < 0.001) of height increment from multiple linear regression analysis ( R = 0.784, R2 = 0.615). PT Cobb angle, lumbar, SB Cobb angle, preoperative height and number of fused segment were not significant predictors for the height increment based on the multivariable analysis. Increase in post-operative height could be calculated by the formula: Increase in height (cm) = (0.09 * preoperative MT Cobb angle) - (0.04 x FB Cobb angle) - 0.5. CONCLUSION: The proposed formula of increase in height (cm) = (0.09 * preoperative MT Cobb angle) - (0.04 * FB Cobb angle) - 0.5 could predict post operative height gain to within 5 mm accuracy in 51% of patients, within 10 mm in 70% and within 15 mm in 86% of patients. PMID- 29185382 TI - In Vitro antileishmania activity of sesquiterpene-rich essential oils from Nectandra species. AB - CONTEXT: New antileishmanias are needed because of toxicity, high cost and resistance problems associated with available drugs. Nectandra (Lauraceae) produces several classes of compounds but its essential oil has not previously been reported to have antileishmania activity. OBJECTIVE: We evaluated the cytotoxicity and antileishmania activity of essential oils from Nectandra amazonum Nees, N. gardneri Meisn., N. hihua (Ruiz & Pav.) Rohwer and N. megapotamica (Spreng.) Mez. MATERIALS AND METHODS: Nectandra oils were extracted from stem bark/leaves by hydrodistillation and compounds were identified by GC MS. Oils were tested against Leishmania infantum and L. amazonensis intracellular amastigotes and nitric oxide production was evaluated. Cytotoxicity was achieved on NIH/3T3 and J774.A1 cells for the selectivity index (SI). RESULTS AND DISCUSSION: Nectandra gardneri was active against L. infantum and L. amazonensis (IC50 = 2.7 +/- 1.3/2.1 +/- 1.06 MUg/mL) and contained 85.4% sesquiterpenes, of which 58.2% was intermediol. Besides low cytotoxicity (SI >11.3), N. gardneri induced a significant increase in NO production by L. infantum-infected macrophages. Nectandra hihua had the best activity on L. infantum amastigotes (IC50 = 0.2 +/- 1.1 MUg/mL). This oil was 89.0% sesquiterpenes, with 28.1% bicyclogermacrene. The two specimens of N. megapotamica had different activities on amastigotes. The one richer in sesquiterpenes (49.9%) was active against both species (IC50 = 12.5 +/- 1.4/21.3 +/- 1.2) and had phenylpropanoid E-asarone as the main compound (42.4%). Nectandra amazonum showed moderate activity on both the species (IC50 = 31.9 +/- 2.0/22.1 +/- 1.3 MUg/mL) and low selectivity (0.9 < SI >2.6), probably due to the major presence of beta-caryophyllene (28.5%). CONCLUSIONS: Our data identify compounds that can now be isolated and used for the development of new antileishmanias. PMID- 29185384 TI - Treatment of displaced flexion-type pediatric supracondylar humeral fractures in the prone position. AB - PURPOSE: This study is to report a new method to reduce and fix the displaced flexion-type pediatric supracondylar fracture in the prone position. METHODS: Ten children with displaced flexion-type supracondylar humeral fractures treated between 2007 and 2013 were reviewed. There were three girls and seven boys, with a mean age of 9.5 years. The fracture was reduced by gentle traction of the forearm and gradual extension of the elbow in the prone position. Two or three crossed Kirschner wires (K-wires) were inserted percutaneously to secure the fracture reduction. Radiographic evaluation included the Baumann's angle and the lateral humerocapitellar angle. Clinical outcomes were assessed using the Flynn's criteria. RESULTS: Eight children had closed reduction and percutaneous K-wire fixation. The other two children required open reduction through a posterior triceps splitting approach. The mean Baumann's angle was 70.2 degrees immediately after K-wires fixation and 69.5 degrees after 3 months later. The mean lateral humerocapitellar angle was 38 degrees immediately after K-wires fixation and 35.5 degrees after 3 months later. The clinical outcome was excellent in nine children and poor in one child by the Flynn's criteria. CONCLUSION: Reduction of displaced flexion-type pediatric supracondylar humeral fractures by traction and gradual extension in the prone position is an effective and safe method. When reduction is still impossible or nerve incarceration is suspected, open reduction and release of the trapped nerve through a posterior triceps splitting approach are simply accessible.

PMID- 29185388 TI - alpha-Lipoic acid, functional fatty acid, as a novel therapeutic alternative for central nervous system diseases: A review. AB - OBJECTIVES: alpha-lipoic acid (ALA) is a natural antioxidant which acts as a cofactor of bioenergetic mitochondrial enzymes. Along with its mitochondrial action, ALA and its reduced form have many biological functions resulting in a wide variety of actions such as anti-inflammation and antioxidant protection, scavenging reactive oxygen species, regenerating other antioxidant agents, such as vitamins C and E, and cytosolic glutathione, chelating the transitional metal ions (e.g. iron and copper), and modulating the signal transduction of nuclear factor. METHODS: By selecting papers from PubMed, Science Direct, EBSCO, and databases, this review discusses the biochemical properties of LA, its mechanism of action, pharmacokinetics, and its possible therapeutic role in central nervous system diseases, such as Alzheimer's disease, Parkinson's disease, Multiple sclerosis, stroke, and spinal cord injury. RESULTS: ALA as an antioxidant and anti-inflammation agent has therapeutical effects on central nervous system diseases, especially multiple sclerosis and PD. DISCUSSION: ALA can be considered as a potentially useful treatment in central nervous disorders. PMID- 29185389 TI - N-acetyl-L-tryptophan, a substance-P receptor antagonist attenuates aluminum induced spatial memory deficit in rats. AB - Neuroinflammation plays an important role in the pathophysiology of Alzheimer's disease. Neurokinin substance P is a key mediator which modulates neuroinflammation through neurokinin receptor. Involvement of substance P in Alzheimer's disease is still plausible and various controversies exist in this hypothesis. Preventing the deleterious effects of substance P using N-acetyl-L tryptophan, a substance P antagonist could be a promising therapeutic strategy. This study was aimed to evaluate the effect of N-acetyl-L-tryptophan on aluminum induced spatial memory alterations in rats. Memory impairment was induced using aluminum chloride (AlCl3) at a dose of 10 mg/kg for 42 d. After induction of dementia, rats were exposed to 30 and 50 mg/kg of N-acetyl-L-tryptophan for 28 d. Spatial memory alterations were measured using Morris water maze. Acetylcholinesterase activity and antioxidant enzyme glutathione level were assessed in hippocampus, frontal cortex and striatum. The higher dose of N-acetyl L-tryptophan (50 mg/kg) significantly improved the aluminum induced memory alterations. N-acetyl-L-tryptophan exposure resulted in significant increase in acetylcholinesterase activity and glutathione level in hippocampus. The neuroprotective effect of N-acetyl-L-tryptophan could be due to its ability to block substance P mediated neuroinflammation, reduction in oxidative stress and anti-apoptotic properties. To conclude, N-acetyl-L-tryptophan may be considered as a novel neuroprotective therapy in Alzheimer's disease. PMID- 29185391 TI - Current status of immunotherapy for sarcomas. AB - Although the development of anticancer drugs has improved the outcomes of bone and soft tissue sarcomas, the clinical outcome of patients with relapsed sarcomas remains unsatisfactory due to therapeutic toxicities and resistance to anticancer drugs. Therefore, novel therapeutic modalities are needed to improve the outcome of patients with bone and soft tissue sarcomas. Dendritic cells present tumor antigens and stimulate immune responses, and immune cells, such as cytotoxic T lymphocytes, kill tumor cells by recognizing tumor antigens. However, immune suppressive conditions by immune regulator PD-1, CTLA-4 and regulatory T cells help tumor growth and progression. In this report, current immunotherapies including cellular immunotherapy and checkpoint inhibitors are introduced, and the advantages and disadvantages of the treatments are discussed. PMID- 29185392 TI - Immunotherapy in head and neck cancer: evidence and perspectives. AB - Head and neck squamous cell carcinomas evade immune response through multiple immunologic resistance mechanisms. Two of the most commonly involved checkpoint inhibitory mechanisms are CTLA-4 and PD-1/PD-L1, which act at earlier and later stages of immune response to tumors. Pembrolizumab and nivolumab are PD-1 antibodies that interrupt the immunosuppressive pathway of inhibitory checkpoints, which are used by tumor cells to prevent immune reaction. Both recently gained US FDA approval for the treatment of patients with recurrent or metastatic head and neck cancer with disease progression during or following platinum containing chemotherapy. No conclusions can be drawn on the role of PD L1 in identifying patients responding to immunotherapy, given that similar studies lead to contrasting results. It will be crucial to identify predictive markers of immunotherapy response, and to evaluate them prospectively. A better understanding of the complex network between tumor, immune system and other oncologic treatments will help us to develop more efficient multimodality treatments. PMID- 29185390 TI - Modulation of antitumor immunity with histone deacetylase inhibitors. AB - Histone deacetylase inhibitors possess a broad array of antitumor activities; however, their net impact on the evolving antitumor immune response is highly dependent on the inhibitors used and the histone deacetylases they target. Herein, we sequentially focus on each stage of the antitumor immune response - from dendritic cell activation and migration, antigen uptake and presentation, T cell activation and differentiation and the enactment of antitumor effector functions within the tumor microenvironment. In particular, we will discuss how various inhibitors have different effects depending on cellular activation, experimental design and specific histone deacetylases being targeted - and how these changes impact the outcome of an antitumor immune response. At last, we consider the impact these inhibitors may have on T-cell exhaustion and implications for combination with other immunomodulating therapies. PMID- 29185393 TI - Chimeric switch receptor: switching for improved adoptive T-cell therapy against cancers. AB - Adoptive T-lymphocyte transfer-based immunotherapy for cancers has seen huge leaps with both CARs and engineered TCRs. Despite this, issues relating to safety and efficacy persist. To address this, chimeric switch receptors have been created to reverse the outcomes of their original signaling pathways in order to confer immune cells with the ability to overcome the immunosuppressive tumor microenvironment and to allow them to have greater in vivo persistence. Activating switch receptors exploit the inhibitory molecules expressed by cancer cells to further stimulate the tumor antigen-specific T lymphocytes. On the other hand, inhibitory switch receptors inhibit the effects of tumor-reactive T lymphocytes on unintended targets. This paper reviews the switch receptors reported thus far, and lists out potential improvements and future works.

PMID- 29185395 TI - PD-L1 expression in tumor metastasis is different between uveal melanoma and cutaneous melanoma. AB - AIM: To compare PD-L1 expression between metastatic uveal melanoma (MUM) and metastatic cutaneous melanoma (MCM). MATERIALS & METHODS: A total of 295 MCM and 78 MUM specimens were analyzed for tumor cell PD-L1 expression. Additionally, 91 MCM and 45 MUM specimens were analyzed for PD-1 expression on tumor-infiltrating lymphocytes. RESULTS: A total of 77/295 (26.1%) MCM specimens expressed PD-L1 as compared to 4/78 (5.1%) MUM specimens (p < 0.0001). PD-1 expression on tumor infiltrating lymphocytes was greater in MCM (73.6%; 67/91) than in MUM (51.1%; 23/45), respectively (p = 0.009). CONCLUSION: Significant differences exist in PD L1 expression between MCM and MUM. The lower PD-L1 expression in MUM may provide a rationale for failure of PD-1 inhibitor therapy and suggests that immune evasion in this disease may occur via alternative mechanisms.

PMID- 29185398 TI - Diaphragmatic Excursion: Does it Predict Successful Weaning from Mechanical Ventilation? AB - OBJECTIVE: To measure the diaphragmatic excursion and its outcome on weaning from mechanical ventilation. STUDY DESIGN: Cross-sectional comparative study. PLACE AND DURATION OF STUDY: Medical Intensive Care Unit (ICU), Military Hospital (MH), Rawalpindi, Pakistan, from January to December 2014. METHODOLOGY: Diaphragmatic excursion (DE) in cm was measured through ultrasound by marking liver and spleen displacement in patients who fulfilled the criteria of removal from ventilatory support. The patients were followed up for 48 hours and classified according to the outcome as successful weaning and weaning failure. RESULTS: Out of 100 cases, 76 patients had a successful weaning while 24 had a failed weaning outcome. At a diaphragmatic excursion of 1.2 cm and more, out of 67 cases, 60 had a successful weaning (89.55%) while 7 cases (10.45%) had a weaning failure. At an excursion of less than 1.2 cm, 17 out of 33 cases (51.5%) had successful weaning while 16 (48.48%) had weaning failure. At this cut off point (1.2 cm), the sensitivity and specificity for successful weaning were 78.95% and 70.83%, respectively. The positive and negative likelihood ratio (LR) for these values being 2.70 and 0.29, respectively. The positive predictive value was 82.35% and negative predictive value 60.00%. CONCLUSION: Ultrasonographic measurement of diaphragmatic excursion is a good method for predicting weaning outcome from mechanical ventilation. PMID- 29185399 TI - Negative Predictive Value of Ultrasound in Predicting Tumor-Free Margins in Specimen Sonography. AB - OBJECTIVE: To evaluate the success of ultrasound in post-excision specimen visualization, and negative predictive value of ultrasound for estimation of tumor-free margins using histopathology as the gold standard. STUDY DESIGN: Cross sectional analytical study. PLACE AND DURATION OF STUDY: The Aga Khan University Hospital, Karachi, Pakistan, from May 2010 till January 2013. METHODOLOGY: Sonography of all breast nodules was done before and after exicision by two female radiologists with at least five years clinical experience. All surgeries were performed by the same referring breast surgeons. All nodules were non palpable and had histopathology as well as specimen sonography performed at AKUH. Subjects were excluded, if histopathology was not available, post-procedure sonogram not done or done in another hospital and nodules that were not seen on ultrasound. After needle localization in 47 patients using ultrasound and in 7 patients using mammogram was done, sonogram was conducted in all 54 lesions. These were then assessed by ultrasound for detection of lesion and tumor-free margins in malignant lesion. Post-excision ultrasound was performed for the evaluation of lesion whether visualized or absent with localizing needle in situ, lesion dimensions, depth measurement between the superior margin of the lesion and its edge. RESULTS: All 54 lesions were present on post-exicison scan, out of which 28 were documented as malignant and 26 as benign. Ultrasound declared all specimens as tumor-free. On histopathology, two lesions were documented as having tumor-positive margins and were proven to be invasive lobular carcinoma. Therefore, the negative predictive value of the specimen sonography for margin detection was 26/28 (92.8%). CONCLUSION: Ultrasound of the excised breast tumor specimen is a simple and reliable technique for confirmation of the tumor-free margins in non-palpable breast lesions. PMID- 29185400 TI - Safety of Trans-Nasal Percutaneous Endoscopic Gastrostomy Placement. AB - OBJECTIVE: To evaluate the safety of trans-nasal percutaneous endoscopic gastrostomy (TPEG) placement for nutrition in patients where oral approach is not possible. STUDY DESIGN: Case-series. PLACE AND DURATION OF STUDY: April 2010 to April 2016 in the Department of Gastroenterology at Liaquat National Hospital, Karachi. METHODOLOGY: Patients underwent trans-nasal PEG placement and were included in this study. Inclusion criteria were either gender of any age and patients referred for PEG tube placement in whom oral PEG tube insertion was not possible. Ultrathin gastroscope (outer diameter of 5.9 mm) was passed through a nostril after assessment and lubrication, the pull technique was used for tube placement. Primary outcome variable of study was the safety of the procedure. The secondary outcome variables were procedure related complications during and 72 hours after the procedure. RESULTS: TPEG placement was successful in all 46 cases. Thirty-one (67.4%) were males. The mean age was 56.63 +/-12.62 years. Dysphagia was the main indication in all cases. Head and neck cancer was the most common indication present in 38 (82.6%) patients. In 36 (78.2%) cases, the procedure was performed under local anesthesia. PEG site infection occurred in one (2.1%) patient. CONCLUSION: TPEG is a safe procedure in patients with oro pharyngeal obstruction, and it should be considered as an alternative approach. PMID- 29185401 TI - Improvement in Therapeutic Ability of Wharton's Jelly Derived Mesenchymal Stem Cells with Vitamin E in Breast Cancer. AB - OBJECTIVE: To assess the role of Vitamin E to improve the survival of Wharton's jelly derived mesenchymal stem cells (WJMSCs) in breast cancer conditions. STUDY DESIGN: An experimental study. PLACE AND DURATION OF STUDY: Centre for Research in Molecular Medicine, University of Lahore, from November 2016 to March 2017. METHODOLOGY: WJMSCs were obtained from umbilical cord tissue with enzyme digestion method. Isolated cells were characterized for CD90 and CD45 by immunocytochemistry. Pretreatment and conjugation therapies of vitamin E in 50mM and 100mM concentration were used on WJMSCs and breast cancer plasma was provided to mimic the cancer conditions, while WJMSCs provided with normal plasma were considered control. Cells' viability, proliferation and death were evaluated by crystal violet staining, MTT assay and LDH assay, respectively. Oxidative stress was observed by activity of anti-oxidant enzymes (GSH, catalase, SOD) and reactive oxygen species (MDA). RESULTS: The isolated cells expressed mesenchymal stem cells marker CD90 and lacked hematopoietic marker CD45. Vitamin E improved the viability and proliferation of WJMSCs in normal plasma, in conjugation with breast cancer plasma and in pretreatment groups but conjugation group showed even better results with concentration of 100mM as compared to the pretreatment group and opposite was observed for LDH assay for cells death analysis. Vitamin E also reduced the oxidative stress in 100mM more pronounced in conjugation group as compared to pretreatment group while left no harmful effects on WJMSCs in normal plasma. CONCLUSION: Vitamin E conjugation with breast cancer conditions significantly improved growth of WJMSCs. Thus vitamin E treated WJMSCs are better therapeutic options for breast cancer. PMID- 29185402 TI - Hearing Status after Radical Mastoidectomy without Tympanoplasty. AB - OBJECTIVE: To find out the impairment of hearing associated with radical mastoidectomy by measuring the quantitative difference in the functional hearing level before and after radical mastoidectomy operation without tympanoplasty. STUDY DESIGN: Cross-sectional comparative study. PLACE AND DURATION OF STUDY: Department of Otorhinolaryngology and Head Neck Surgery, Bahawal Victoria Hospital, Bahawalpur and PNS Shifa Hospital, Karachi, from November 2009 to January 2013. METHODOLOGY: Eighty-five patients, diagnosed clinically as chronic suppurative otitis media with extensive cholesteatoma having history of ear discharge and hearing impairment for more than 6 weeks duration and requiring radical mastoidectomy for treatment, were included in this study. Pure tone audiogram was done before and after radical mastoidectomy. Hearing impairment was compared in each patient before and after the operation. RESULTS: Among the 85 patients, 54 (63.5%) were males and 31 (36.5%) were females, with the age ranged between 18 to 63 years, mean age being 42.31 4.8 years. The mean increase in hearing loss after radical mastoidectomy in air conduction was 7.19 dB, bone conduction was 4.16 dB, and air-bone gap was 3.75 dB (0.001). The ear became dry and safe in 82 patients (96.5%) out of a total of 85, and only 3 patients required revision surgery at a second stage. CONCLUSION: Radical mastoidectomy has a least negligible effect on hearing status and one should not limit this technique due to the concern of aggravated hearing in patients with extensive cholesteatoma at the cost of dry and safe ears, which should be of prime importance. PMID- 29185403 TI - Effect of Femtosecond Laser-Assisted Cataract Surgery (FLACS) on Endothelial Cell Count. AB - OBJECTIVE: To compare the change in endothelial cell count after femtosecond laser-assisted cataract surgery (FLACS) versus conventional phacoemulsification. STUDY DESIGN: Randomized controlled clinical trial. PLACE AND DURATION OF STUDY: Armed Forces Institute of Ophthalmology, Rawalpindi, Pakistan from January 2016 to August 2017. METHODOLOGY: Patients with senile cataract and age ranging from 40 to 80 years were included in the study. Patients with any other cause of endothelial cell loss, history of trauma, documented diabetes millitis, hypertention and glaucoma were excluded. Preoperative detailed ocular examination, including both anterior and posterior examination, was carried out. Patients were distributed into two groups. Group GP were planned for conventional phacoemulsification, while group GF underwent FLACS. All the surgeries were performed under local anesthesia by same ophthalmic surgeon. Specular microscope (Topcon specular microscope sp-3000p) was utilized to measure the endothelial cell count (ECC) before and 4 weeks after the surgery. RESULTS: Fifty eyes (25 in each group) of 48 patients underwent cataract surgery by phacoemulsification or FLACS. Twenty-five (52.08%) out of the total were females while 23 (47.91%) were males. Median age of the participants in phacoemulsification group was 55 years (IQR 20.50), while in FLACS group it was 54 years (IQR 8). The median change in endothelial cell count was 228 (IQR 532) in Phaco group, while 23 (IQR 35) in FLACS group. (p<0.05 Mann Whitney U-test). CONCLUSION: FLACS is a safe and effective modality for cataract treatment and it induces significantly less endothelial cell loss than conventional phacoemulsification. PMID- 29185404 TI - High Burden of Subclinical Lead Toxicity after Phase Out of Lead from Petroleum in Pakistan. AB - OBJECTIVE: To evaluate the frequency of subclinical lead toxicity. STUDY DESIGN: Cross-sectional study. PLACE AND DURATION OF STUDY: Department of Pathology and Laboratory Medicine, The Aga Khan University Hospital, Karachi, from January 2011 to December 2014. METHODOLOGY: Analysis of laboratory data for blood lead levels (BLL) was performed. Lead was tested by atomic absorption spectrometer. For all subjects, only initial test results were included while the results of repeated testing were excluded. Exemption was sought from institutional ethical review committee. BLL of 2-10 ug/dl and 10-70 ug/dl in children and adults, respectively were taken as subclinical lead toxicity. RESULTS: Amongst the total number of subjects tested (n=524), 26.5% (n=139) were children (<16 years) while rest were adults. Overall median BLLs was 6.4 ug/dl (20.9-3.1). The median BLL was 4 ug/dl (6.7-2.6) in children and 8.3 ug/dl (27.9-3.4) in adults, respectively. The BLL increased with age; higher levels were observed in age range 21-30 years of subjects [median lead level 16.9 ug/dl (36.1-4)] and lower level [4.2 ug/dl (6.8 2.6)] in children with <10 years of age. Only 16% (n=22) children had desirable lead levels while most had either subclinical (76%, n=106) or toxic lead levels (8%, n=11). In adults, (55%, n=212) subjects had desired lead levels, and 40% (n=154) and 4.99% (n=19) had subclinical and toxic lead levels. CONCLUSION: Presence of subclinical lead poisoning even after phasing out of lead petroleum in Pakistanis is alarming, especially in children. A national population-based study to determine the lead status and targeted intervention to identify potential sources is need of the time.

AB - OBJECTIVE: To evaluate the action of 2% lidocaine on the culture results of bronchial fluid in patients suspected of having lower respiratory tract infections. STUDY DESIGN: Cross-sectional analytical study. PLACE AND DURATION OF STUDY: Shahid Sadoughi Hospital, Yazd, Iran, from November 2014 to November 2015. METHODOLOGY: Patients suspected of lower respiratory tract infections referred to bronchoscopy unit of the Hospital were included. Those with incomplete questionnaire and bronchoscopy contraindication were excluded. Bronchial fluid was aspirated before and after local application of 2% lidocaine and cultured, according to the suspected clinical diagnosis. Finally, statistical analysis was performed using SPSS software, version 17.0. For statistical comparisons, McNemar's test was used. Level of significance was kept at p <0.05. RESULTS: The mean age of the study population was 51.83 +/-15.93 with a range of 25 - 80 years. Out of 130 patients, 60 patients had positive culture results. Nineteen (31.7%) cases had positive culture for tuberculosis and 41 (63.3%) cases had positive results for other bacteria before intervention that did not change after using 2% lidocaine (p=1). In 70 (53.84%) cases, results were negative before and after use of 2% lidocaine. CONCLUSION: No significant difference was found between culture results before and after the use of lidocaine. Therefore, lidocaine can be used during bronchoscopy to increase patient tolerance. PMID- 29185406 TI - Anaesthetic Management of Supratentorial Tumor Craniotomy Using Awake-Throughout Approach. AB - The authors are reporting an anaesthetic management of patient presenting with left parietal lobe space occupying lesion and scheduled for Awake-craniotomy. Awake-throughout approach using scalp block was planned. Among techniques reported for keeping patient awake during the surgery, this one is really underutilized. The successful conduct requires thorough preoperative assessment and psychological preparation. We used powerpoint presentation as a preoperative teaching tool. The anatomical landmark technique was used to institute scalp block, where individual nerves were targeted bilaterally. Patient remained stable throughout and participated actively in intraoperative neurological monitoring. Postoperative period showed remarkable recovery, better pain control, and shorter length of stay in hospital. PMID- 29185407 TI - Duodenal Perforation due to Ingested Partial Denture. AB - Ingestion of foreign bodies including dentures can be a cause of morbidity and mortality. We report a case of poor-fit denture in an elderly male with pulmonary and musculoskeletal comorbidities, who presented as an acute abdomen. The pin attached to the denture caused perforation of first part of duodenum. The only positive finding prior to surgery was a radiopaque density in the abdominal radiograph of the patient and air under the diaphragm. It is important for all the surgeons dealing with acute care patients to be aware of different designs and constructions of dentures. PMID- 29185408 TI - High Altitude Retinopathy Presenting as Central Retinal Vein Occlusion in a Soldier. AB - A 33-year soldier, deployed at an altitude of 3,350 meters for two years, developed unilateral Central Retinal Vein Occlusion (CRVO) in the left eye. He had no risk factor for thrombosis and all thrombophilia screenings were negative. The patient was managed with intravitreal injections of anti-VEGF (Bevacizumab) every four weeks. He showed gradual improvement in the visual acuity over the next 3 months. Best corrected visual acuity (BCVA) after three months was 6/7.5; whereas, initially it was limited to hand movements only. This case illustrates that prolonged exposure to high altitude is a risk factor for CRVO, too. Frequent eye examination, including fundus, should be carried out among people living at such altitudes. PMID- 29185409 TI - Transient Methemoglobinemia in three Neonates due to Maternal Pudendal Anesthesia. AB - Methemoglobin (MetHb) is a form of hemoglobin which contains iron in ferric state. The delivery of oxygen to tissues is impaired and cellular hypoxia develops with an increase in MetHb levels. Methemoglobinemia is a rare but potentially lethal complication of local anesthetics. In this clinical brief, three cases of transient neonatal methemoglobinemia, caused by maternal pudendal anesthesia with prilocaine, are reported. PMID- 29185410 TI - Parvovirus B19: A Rare Cause of Post-renal Transplant Anemia. AB - Parvovirus B19 infection should be contemplated as one of the differential diagnoses of persistent anemia in transplanted patients. There must be high index of suspicion of Parvovirus B19, when post-transplant patients present with refractory and severe anemia with reticulocytopenia and all the other common causes of anemia such as blood loss, adverse effects of immunosuppressant agents and graft dysfunction has been ruled out. In suspected patients, diagnosis is confirmed by serological tests (IgM and IgG), PCR from blood and/or bone marrow and by bone marrow biopsy finding of pure red cell aplasia. Intravenous immunoglobulin (IVIG) is the treatment of choice and highly rewarding. Here we are reporting two cases of post-transplant Parvovirusinfection, one in an adult lady and second in an adult man who underwent live renal transplantation recently. PMID- 29185411 TI - Predicament in Detection and Reporting of Extended Spectrum Beta Lactamase Production in Routine Antibiotic Susceptibility Testing. AB - This descriptive and cross-sectional study was planned to determine the dilemma of inadvertent detection of extended spectrum beta lactamase (ESBL) production in Enterobacteriaceaewhen using inhibition zone size of antibiotic disks of Cefotaxime or Aztreonam in routine antibiotic susceptibility testing as recommended by Clinical Laboratory Standards Institute (CLSI). Screening and double disk tests were adopted as per CLSI. Escherichia coli ATCC 25922 was used as control strain. Among total specimens of 5346, there were 348 isolates of Escherichia coli(n=235), Klebsiella pneumonia (n=92), Klebsiella oxytoca(n=3) or Proteus mirabilus(n=18). The screening method recommended by CLSI significantly falsely detected ESBL production in 79 (32.3%) isolates (p<0.0001). ESBL detection is important as its frequency is high and treatment of the infection varies with the presence and absence of ESBL. To avoid false reporting, proper phenotypic detection of ESBL confirmatory method-like double-disk synergy test, should be used routinely.

PMID- 29185419 TI - Activation of Discs large by aPKC aligns the mitotic spindle to the polarity axis during asymmetric cell division. AB - Asymmetric division generates cellular diversity by producing daughter cells with different fates. In animals, the mitotic spindle aligns with Par complex polarized fate determinants, ensuring that fate determinant cortical domains are bisected by the cleavage furrow. Here, we investigate the mechanisms that couple spindle orientation to polarity during asymmetric cell division of Drosophila neuroblasts. We find that the tumor suppressor Discs large (Dlg) links the Par complex component atypical Protein Kinase C (aPKC) to the essential spindle orientation factor GukHolder (GukH). Dlg is autoinhibited by an intramolecular interaction between its SH3 and GK domains, preventing Dlg interaction with GukH at cortical sites lacking aPKC. When co-localized with aPKC, Dlg is phosphorylated in its SH3 domain which disrupts autoinhibition and allows GukH recruitment by the GK domain. Our work establishes a molecular connection between the polarity and spindle orientation machineries during asymmetric cell division.

PMID- 29185435 TI - Terahertz spectral unmixing based method for identifying gastric cancer. AB - At present, many researchers are exploring biological tissue inspection using terahertz time-domain spectroscopy (THz-TDS) techniques. In this study, based on a modified hard modeling factor analysis method, terahertz spectral unmixing was applied to investigate the relationships between the absorption spectra in THz TDS and certain biomarkers of gastric cancer in order to systematically identify gastric cancer. A probability distribution and box plot were used to extract the distinctive peaks that indicate carcinogenesis, and the corresponding weight distributions were used to discriminate the tissue types. The results of this work indicate that terahertz techniques have the potential to detect different levels of cancer, including benign tumors and polyps. PMID- 29185436 TI - Objective image characterization of a spectral CT scanner with dual-layer detector. AB - This work evaluated the performance of a detector-based spectral CT system by obtaining objective reference data, evaluating attenuation response of iodine and accuracy of iodine quantification, and comparing conventional CT and virtual monoenergetic images in three common phantoms. Scanning was performed using the hospital's clinical adult body protocol. Modulation transfer function (MTF) was calculated for a tungsten wire and visual line pair targets were evaluated. Image noise power spectrum (NPS) and pixel standard deviation were calculated. MTF for monoenergetic images agreed with conventional images within 0.05 lp cm-1. NPS curves indicated that noise texture of 70 keV monoenergetic images is similar to conventional images. Standard deviation measurements showed monoenergetic images have lower noise except at 40 keV. Mean CT number and CNR agreed with conventional images at 75 keV. Measured iodine concentration agreed with true concentration within 6% for inserts at the center of the phantom. Performance of monoenergetic images at detector based spectral CT is the same as, or better than, that of conventional images. Spectral acquisition and reconstruction with a detector based platform represents the physical behaviour of iodine as expected and accurately quantifies the material concentration. PMID- 29185437 TI - Hierarchy and scaling behavior of multi-rank domain patterns in ferroelectric K0.9Na0.1NbO3 strained films. AB - The formation process of a ferroelectric multi-rank domain pattern in the thickness range of 7-52 nm is investigated for monoclinic K0.9Na0.1NbO3 strained epitaxial films on (110) NdScO3 substrates. Although the elastic strain energy density is degenerated for two pseudocubic orientations, a distinctive hierarchy of domain evolution is observed with exclusive in-plane a1a2 domains for very thin films and the retarded onset of a ferroelectric MC phase at larger film thickness. This is accompanied by a thickness dependent transformation from stripe domains to a herringbone pattern and, eventually, for the thickest film, to a checkerboard-like structure. These transformations in the domain arrangement and width are correlated to energetic aspects as depolarization field and anisotropic strain relaxation in the film. While for the MC domains plastic strain relaxation is throughout observed, the a1a2 domains show a two-step strain relaxation mechanism starting with an in-plane elastic shearing, which is followed by plastic lattice relaxation. Our results highlight a pathway for engineering and patterning of periodic ferroelectric domain structures. PMID- 29185438 TI - Emerging optical properties from the combination of simple optical effects. AB - Structural color arises from the patterning of geometric features or refractive indices of the constituent materials on the length-scale of visible light. Many different organisms have developed structurally colored materials as a means of creating multifunctional structures or displaying colors for which pigments are unavailable. By studying such organisms, scientists have developed artificial structurally colored materials that take advantage of the hierarchical geometries, frequently employed for structural coloration in nature. These geometries can be combined with absorbers-a strategy also found in many natural organisms-to reduce the effects of fabrication imperfections. Furthermore, artificial structures can incorporate materials that are not available to nature in the form of plasmonic nanoparticles or metal layers-leading to a host of novel color effects. Here, we explore recent research involving the combination of different geometries and materials to enhance the structural color effect or to create entirely new effects, which cannot be observed otherwise. PMID- 29185439 TI - A survey on the pattern of dermoscopy use among dermatologists in India. AB - INTRODUCTION AND BACKGROUND: Dermoscopy is being increasingly used for improving dermatological diagnosis. Use of dermoscopy in the early recognition of skin malignancies, especially melanoma, is well established. Of late, its use in general clinical dermatology is growing with the recognition of new and specific patterns in conditions such as hair disorders, inflammatory disorders, and infections/infestations. This cross-sectional survey aims to assess the common patterns of dermoscopy use by Indian dermatologists. METHODS: This was across sectional survey. An online questionnaire was used to collect data. The questionnaire focused on the frequency of dermoscopy use by Indian dermatologists, reasons for using it or not, and the training they had received on dermoscopy. RESULTS: Of the total 150 valid responses, eighty two (54.7%) participants reported that they were using dermoscopy routinely in their clinical practice. Lack of familiarity and lack of proper training were the important reasons cited for not using dermoscopy regularly. Among the dermatologists using dermoscopy, consensus on effectiveness was highest for hair disorders. CONCLUSIONS: Dermoscopy use by dermatologists in India is mainly in the context of inflammatory dermatosis and hair disorders rather than skin tumors. Lack of familiarity with the technique appears to be main factor limiting the use of dermoscopy in India. LIMITATIONS: Small sample size is the major limitation of this study. It is possible that a large number of dermatologists who do not use dermoscopy might not have responded to the survey, there by affecting the results and their interpretation. PMID- 29185440 TI - Risk of venous thromboembolism in patients with bullous pemphigoid: A systematic review and meta-analysis. AB - BACKGROUND AND OBJECTIVES: Increased risk of venous thromboembolism is observed in several autoimmune inflammatory disorders. However, data on bullous pemphigoid, one of the most common autoimmune blistering disorders, is limited. This systematic review and meta-analysis was conducted to summarize all available evidence. METHODS: Two investigators independently searched published studies indexed in MEDLINE and EMBASE from inception to July 2016 using the terms for bullous pemphigoid and venous thromboembolism. The inclusion criteria were as follows: (1) cohort or case-control study evaluated the association between bullous pemphigoid and risk of venous thromboembolism, (2) effect estimates were provided as odds ratios, relative risk, hazard ratio, standardized incidence ratio with 95% confidence intervals, and (3) subjects without bullous pemphigoid were used as comparators for cohort studies, while subjects without venous thromboembolism were used as comparators for case-control studies. Point estimates and 95% confidence intervals were extracted from each study and were pooled together using the random-effect model, generic inverse variance method of DerSimonian and Laird. Cochran's Q test and the I2 statistic were used to evaluate the statistical heterogeneity. RESULTS: Two retrospective cohort studies, one prospective cohort study, and one case-control study met the eligibility criteria and were included in the meta-analysis. The pooled odds ratio was 2.69 (95% confidence interval, 1.79-4.05). Statistical heterogeneity was high with I2 of 77%. LIMITATION: Limited accuracy of diagnosis of primary studies and high between-study heterogeneity. CONCLUSION: This meta-analysis demonstrated that patients with bullous pemphigoid have a significantly increased risk of venous thromboembolism. PMID- 29185441 TI - Intracellular localization of nanoparticle dimers by chirality reversal. AB - The intra- and extracellular positioning of plasmonic nanoparticles (NPs) can dramatically alter their curative/diagnostic abilities and medical outcomes. However, the inability of common spectroscopic identifiers to register the events of transmembrane transport denies their intracellular vs. extracellular localization even for cell cultures. Here we show that the chiroptical activity of DNA-bridged NP dimers allows one to follow the process of internalization of the particles by the mammalian cells and to distinguish their extra- vs intra cellular localizations by real-time spectroscopy in ensemble. Circular dichroism peaks in the visible range change from negative to positive during transmembrane transport. The chirality reversal is associated with a spontaneous twisting motion around the DNA bridge caused by the large change in electrostatic repulsion between NPs when the dimers move from interstitial fluid to cytosol. This finding opens the door for spectroscopic targeting of plasmonic nanodrugs and quantitative assessment of nanoscale interactions. The efficacy of dichroic targeting of chiral nanostructures for biomedical applications is exemplified here as photodynamic therapy of malignancies. The efficacy of cervical cancer cell elimination was drastically increased when circular polarization of incident photons matched to the preferential absorption of dimers localized inside the cancer cells, which is associated with the increased generation of reactive oxygen species and their preferential intracellular localization. PMID- 29185442 TI - Synergistic gene expression during the acute phase response is characterized by transcription factor assisted loading. AB - The cytokines interleukin 1beta and 6 (IL-1beta, IL-6) mediate the acute phase response (APR). In liver, they regulate the secretion of acute phase proteins. Using RNA-seq in primary hepatocytes, we show that these cytokines regulate transcription in a bifurcated manner, leading to both synergistic and antagonistic gene expression. By mapping changes in enhancer landscape and transcription factor occupancy (using ChIP-seq), we show that synergistic gene induction is achieved by assisted loading of STAT3 on chromatin by NF-kappaB. With IL-6 treatment alone, STAT3 does not efficiently bind 20% of its coordinated binding sites. In the presence of IL-1beta, NF-kappaB is activated, binds a subset of enhancers and primes their activity, as evidenced by increasing H3K27ac. This facilitates STAT3 binding and synergistic gene expression. Our findings reveal an enhancer-specific crosstalk whereby NF-kappaB enables STAT3 binding at some enhancers while perturbing it at others. This model reconciles seemingly contradictory reports of NF-kappaB-STAT3 crosstalk. PMID- 29185443 TI - A Feline HFpEF Model with Pulmonary Hypertension and Compromised Pulmonary Function. AB - Heart Failure with preserved Ejection Fraction (HFpEF) represents a major public health problem. The causative mechanisms are multifactorial and there are no effective treatments for HFpEF, partially attributable to the lack of well established HFpEF animal models. We established a feline HFpEF model induced by slow-progressive pressure overload. Male domestic short hair cats (n = 20), underwent either sham procedures (n = 8) or aortic constriction (n = 12) with a customized pre-shaped band. Pulmonary function, gas exchange, and invasive hemodynamics were measured at 4-months post-banding. In banded cats, echocardiography at 4-months revealed concentric left ventricular (LV) hypertrophy, left atrial (LA) enlargement and dysfunction, and LV diastolic dysfunction with preserved systolic function, which subsequently led to elevated LV end-diastolic pressures and pulmonary hypertension. Furthermore, LV diastolic dysfunction was associated with increased LV fibrosis, cardiomyocyte hypertrophy, elevated NT-proBNP plasma levels, fluid and protein loss in pulmonary interstitium, impaired lung expansion, and alveolar-capillary membrane thickening. We report for the first time in HFpEF perivascular fluid cuff formation around extra-alveolar vessels with decreased respiratory compliance. Ultimately, these cardiopulmonary abnormalities resulted in impaired oxygenation. Our findings support the idea that this model can be used for testing novel therapeutic strategies to treat the ever growing HFpEF population.

PMID- 29185444 TI - Directing intracellular supramolecular assembly with N-heteroaromatic quaterthiophene analogues. AB - Self-assembly in situ, where synthetic molecules are programmed to organize in a specific and complex environment i.e., within living cells, can be a unique strategy to influence cellular functions. Here we present a small series of rationally designed oligothiophene analogues that specifically target, locate and dynamically self-report their supramolecular behavior within the confinement of a cell. Through the recognition of the terminal alkyl substituent and the amphiphilic pyridine motif, we show that the cell provides different complementary pathways for self-assembly that can be traced easily with fluorescence microscopy as their molecular organization emits in distinct fluorescent bands. Importantly, the control and induction of both forms are achieved by time, temperature and the use of the intracellular transport inhibitor, bafilomycin A1. We showcase the importance of both intrinsic (cell) and extrinsic (stimulus) factors for self-organization and the potential of such a platform toward developing synthetic functional components within living cells. PMID- 29185446 TI - Penultimate deglacial warming across the Mediterranean Sea revealed by clumped isotopes in foraminifera. AB - The variability of seawater temperature through time is a critical measure of climate change, yet its reconstruction remains problematic in many regions. Mg/Ca and oxygen isotope (delta 18OC) measurements in foraminiferal carbonate shells can be combined to reconstruct seawater temperature and delta 18O (delta 18OSW). The latter is a measure of changes in local hydrology (e.g., precipitation/evaporation, freshwater inputs) and global ice volume. But diagenetic processes may affect foraminiferal Mg/Ca. This restricts its potential in many places, including the Mediterranean Sea, a strategic region for deciphering global climate and sea-level changes. High alkalinity/salinity conditions especially bias Mg/Ca temperatures in the eastern Mediterranean (eMed). Here we advance the understanding of both western Mediterranean (wMed) and eMed hydrographic variability through the penultimate glacial termination (TII) and last interglacial, by applying the clumped isotope (Delta 47) paleothermometer to planktic foraminifera with a novel data-processing approach. Results suggest that North Atlantic cooling during Heinrich stadial 11 (HS11) affected surface-water temperatures much more in the wMed (during winter/spring) than in the eMed (during summer). The method's paired Delta 47 and delta 18OC data also portray delta 18OSW. These records reveal a clear HS11 freshwater signal, which attenuated toward the eMed, and also that last interglacial surface warming in the eMed was strongly amplified by water-column stratification during the deposition of the organic-rich (sapropel) interval known as S5. PMID- 29185447 TI - Identification and characterization of genes involving the early step of Juvenile Hormone pathway in Helicoverpa armigera. AB - Juvenile hormones (JHs) are crucial regulators for multiple physiological processes in insects. In the current study, 10 genes in mevalonate pathway involved in JH biosynthesis were identified from Helicoverpa armigera. Tissue specific expression analysis showed that six genes were highly expressed in the head which contained the JH biosynthetic gland (corpora allata). Temporal expression pattern showed that 10 of 12 genes were highly transcribed in the late 2nd-instar when the in vivo JH titer reached the peak, indicating a tight correlation between JH titer and the transcription of JH synthetic pathway genes. Moreover, ingestion of methoprene, a JH analogue, significantly suppressed the transcription of nine JH biosynthetic genes and caused a feedback upregulation of the JH degradation enzyme. Particularly, the Acetoacetyl CoA thiolase (HaAce) and Farnesyl diphosphate synthase gene 4 (HaFpps4) showed high transcript abundance, and their temporal expressions keep pace with JH fluctuations. Further study by RNAi showed that knockdown of HaFpps4 caused the decrease of JH titer, led to a negative effect on the transcript levels of other genes in JH pathway, and resulted in molting disturbance in larvae. Altogether, these results contribute to our understanding of JH biosynthesis in H. armigera and provide target genes for pest control based on JH-dependent regulation. PMID- 29185448 TI - Generation of gene-edited rats by delivery of CRISPR/Cas9 protein and donor DNA into intact zygotes using electroporation. AB - The generation of gene-edited animals using the CRISPRs/Cas9 system is based on microinjection into zygotes which is inefficient, time consuming and demands high technical skills. We report the optimization of an electroporation method for intact rat zygotes using sgRNAs and Cas9 protein in combination or not with ssODNs (~100 nt). This resulted in high frequency of knockouts, between 15 and 50% of analyzed animals. Importantly, using ssODNs as donor template resulted in precise knock-in mutations in 25-100% of analyzed animals, comparable to microinjection. Electroporation of long ssDNA or dsDNA donors successfully used in microinjection in the past did not allow generation of genome-edited animals despite dsDNA visualization within zygotes. Thus, simultaneous electroporation of a large number of intact rat zygotes is a rapid, simple, and efficient method for the generation of a variety of genome-edited rats.

AB - Switching magnetization in a perpendicular magnetic tunnel junction (pMTJ) via voltage controlled magnetic anisotropy (VCMA) has shown the potential to markedly reduce switching energy. However, the requirement of an external magnetic field poses a critical bottleneck for its practical applications. In this work, we propose an elliptical-shaped pMTJ to eliminate the requirement of providing an external field by an additional circuit. We demonstrate that a 10 nm thick in plane magnetized bias layer (BL) separated by a metallic spacer of 3 nm from the free layer (FL) can be engineered within the MTJ stack to provide the 50 mT bias magnetic field for switching. By conducting macrospin simulation, we find that a fast switching in 0.38 ns with energy consumption as low as 0.3 fJ at a voltage of 1.6 V can be achieved. Furthermore, we study the phase diagram of switching probability, showing that a pulse duration margin of 0.15 ns is obtained and low voltage operation (~1 V) is favored. Finally, the MTJ scalability is considered, and it is found that scaling down may not be appealing in terms of both the energy consumption and the switching time for precession based VCMA switching. PMID- 29185450 TI - Evaluation of BMMSCs-EPCs sheets for repairing alveolar bone defects in ovariectomized rats. AB - The aim of this paper is to investigate the effect that bone marrow mesenchymal stem cells (BMMSCs) - endothelial progenitor cells (EPCs), BMMSCs and EPCs sheets have on repairing maxillary alveolar defects in ovariectomized (OVX) rats. In this study, after identification using multi-lineage differentiation and flow cytometry, BMMSCs and EPCs were isolated from female rats. The BMMSCs-EPCs, BMMSCs and EPCs sheets were detected by hematoxylin-eosin (H&E) staining, alkaline phosphatase (ALP) staining and qRT-PCR. Defects were created in maxillary alveoli and repaired with BMMSCs-EPCs, BMMSCs and EPCs sheets in OVX rats. The repair effects were determined by histological staining and micro-CT analysis at 2, 4 and 8 weeks after implantation. We aim to clarify whether BMMSCs EPCs sheets are more effective in repairing alveolar bone defects than are BMMSCs and EPCs sheets in OVX rats. The results show that the osteogenic potential and the effect of bone repair are greater in the BMMSCs-EPCs sheet group and that this group has a higher ability to repair alveolar bone defects in OVX rats. These results suggest that BMMSCs-EPCs sheets have potential in clinical applications for treating humans with osteoporosis. PMID- 29185451 TI - Greenhouse gases emissions in rivers of the Tibetan Plateau. AB - Greenhouse gases (GHGs) emissions from streams are important to regional biogeochemical budgets. This study is one of the first to incorporate stream GHGs (CO2, CH4 and N2O) concentrations and emissions in rivers of the Tibetan Plateau. With one-time sampling from 32 sites in rivers of the plateau, we found that most of the rivers were supersaturated with CO2, CH4 and N2O during the study period. Medians of partial pressures of CO2 (pCO2), pCH4 and pN2O were presented 864 MUatm, 6.3 MUatm, and 0.25 MUatm respectively. Based on a scaling model of the flux of gas, the calculated fluxes of CO2, CH4 and N2O (3,452 mg-C m2 d-1, 26.7 mg-C m2 d-1 and 0.18 mg-N m2 d-1, respectively) in rivers of the Tibetan Plateau were found comparable with most other rivers in the world; and it was revealed that the evasion rates of CO2 and CH4 in tributaries of the rivers of the plateau were higher than those in the mainstream despite its high altitude. Furthermore, concentrations of GHGs in the studied rivers were related to dissolved carbon and nitrogen, indicating that riverine dissolved components could be used to scale GHGs envision in rivers of the Tibetan Plateau. PMID- 29185452 TI - DHHC5-mediated palmitoylation of S1P receptor subtype 1 determines G-protein coupling. AB - Sphingosine 1-phosphate (S1P) is a pleiotropic lipid mediator involved in the regulation of immune cell trafficking and vascular permeability acting mainly through G-protein-coupled S1P receptors (S1PRs). However, mechanism underlying how S1PRs are coupled with G-proteins remains unknown. Here we have uncovered that palmitoylation of a prototypical subtype S1P1R is prerequisite for subsequent inhibitory G-protein (Gi) coupling. We have identified DHHC5 as an enzyme for palmitoylation of S1P1R. Under basal conditions, S1P1R was functionally associated with DHHC5 in the plasma membranes (PM) and was fully palmitoylated, enabling Gi coupling. Upon stimulation, the receptor underwent internalisation leaving DHHC5 in PM, resulting in depalmitoylation of S1P1R. We also revealed that while physiological agonist S1P-induced endocytosed S1P1R readily recycled back to PM, pharmacological FTY720-P-induced endocytosed S1P1R positive vesicles became associated with DHHC5 in the later phase, persistently transmitting Gi signals there. This indicates that FTY720-P switches off the S1P signal in PM, while switching on its signal continuously inside the cells. We propose that DHHC5-mediated palmitoylation of S1P1R determines Gi coupling and its signalling in a spatio/temporal manner.

AB - Graphitic carbons' unique attributes have attracted worldwide interest towards their development and application. Carbon pyrolysis is a widespread method for synthesizing carbon materials. However, our understanding of the factors that cause differences in graphitization of various pyrolyzed carbon precursors is inadequate. We demonstrate how electro-mechanical aspects of the synthesis process influence molecular alignment in a polymer precursor to enhance its graphitization. Electrohydrodynamic forces are applied via electrospinning to unwind and orient the molecular chains of a non-graphitizing carbon precursor, polyacrylonitrile. Subsequently, exerting mechanical stresses further enhances the molecular alignment of the polymer chains during the formative crosslinking phase. The stabilized polymer precursor is then pyrolyzed at 1000 degrees C and characterized to evaluate its graphitization. The final carbon exhibits a uniformly graphitized structure, abundant in edge planes, which translates into its electrochemical kinetics. The results highlight the significance of physical synthesis conditions in defining the structure and properties of pyrolytic carbons.

AB - YAP is a downstream nuclear transcription factor of Hippo pathway which plays an essential role in development, cell growth, organ size and homeostasis. It was previously identified that elevation of YAP in genomics of genetic engineered mouse (GEM) model of prostate cancer is associated with Pten/Trp53 inactivation and ARF elevation hypothesizing the essential crosstalk of AKT/mTOR/YAP with ARF in prostate cancer. However, the detailed function and trafficking of YAP in cancer cells remains unclear. Using GEM microarray model, we found ARF dysregulates Hippo and Wnt pathways. In particular, ARF knockdown reduced non nuclear localization of YAP which led to an increase in F-actin. Mechanistically, ARF knockdown suppressed protein turnover of beta-catenin/YAP, and therefore enhanced the activity of AKT and phosphorylation of YAP. Moreover, we found tea derived carbon dots can interact with ARF in nucleus that may further lead to the non-nuclear localization of YAP. Thus, we reported a novel crosstalk of ARF/beta catenin dysregulated YAP in Hippo pathway and a new approach to stimulate ARF mediated signaling to inhibit nuclear YAP using nanomaterials implicating an innovative avenue for treatment of cancer. PMID- 29185455 TI - Antiphospholipid antibodies increase the levels of mitochondrial DNA in placental extracellular vesicles: Alarmin-g for preeclampsia. AB - The pathogenesis of preeclampsia remains unclear but placental factors are known to play a crucial role causing maternal endothelial cell dysfunction. One potential factor is placental micro- and nano- vesicles. Antiphospholipid antibodies (aPL) increase the risk of preeclampsia ten-fold, in part by damaging the mitochondria in the syncytiotrophoblast. Since mitochondrial DNA (mtDNA) is a danger- associated molecular pattern (DAMP/alarmin) that may activate endothelial cells, the aims of the current study were to investigate whether aPL affect the number of placental vesicles extruded, their mtDNA content and their ability to activate endothelial cells. Exposure of first trimester human placental explants to aPL affected neither the number nor size of extruded micro- and nano- vesicles (n = 5), however their levels of mtDNA were increased (n = 6). These vesicles significantly activated endothelial cells (n = 5), which was prevented by blocking toll-like receptor 9 (TLR-9), a receptor for extracellular DNA. Thus, aPL may increase the risk of preeclampsia in part by increasing the amount of mtDNA associated with placental vesicles. That mitochondrial DNA is recognised as a DAMP by TLR-9 to cause endothelial cell activation, raises the possibility that placental vesicles or TLR-9 might be a target for pharmaceutical intervention to reduce the consequences of aPL in pregnancy. PMID- 29185456 TI - Tabby graphene: Dimensional magnetic crossover in fluorinated graphite. AB - Tabby is a pattern of short irregular stripes, usually related to domestic cats. We have produced Tabby patterns on graphene by attaching fluorine atoms running as monoatomic chains in crystallographic directions. Separated by non-fluorinated sp 2 carbon ribbons, sp 3-hybridized carbon atoms bonded to zigzag fluorine chains produce sp 2-sp 3 interfaces and spin-polarized edge states localized on both sides of the chains. We have compared two kinds of fluorinated graphite samples C2F x , with x near to 1 and x substantially below 1. The magnetic susceptibility of C2F x (x < 1) shows a broad maximum and a thermally activated spin gap behaviour that can be understood in a two-leg spin ladder model with ferromagnetic legs and antiferromagnetic rungs; the spin gap constitutes about 450 K. Besides, stable room-temperature ferromagnetism is observed in C2F x (x < 1) samples: the crossover to a three-dimensional magnetic behaviour is due to the onset of interlayer interactions. Similarly prepared C2F x (x ~ 1) samples demonstrate features of two-dimensional magnetism without signs of high temperature magnetic ordering, but with transition to a superparamagnetic state below 40 K instead. The magnetism of the Tabby graphene is stable until 520 K, which is the temperature of the structural reconstruction of fluorinated graphite. PMID- 29185457 TI - A first assessment of Fraxinus excelsior (common ash) susceptibility to Hymenoscyphus fraxineus (ash dieback) throughout the British Isles. AB - Ash dieback (ADB), caused by Hymenoscyphus fraxineus, has severely damaged a large proportion of ash trees (Fraxinus excelsior) in continental Europe. We have little damage data for the British Isles where the disease was found only five years ago in the Southeast, and is still spreading. A large-scale screening trial to evaluate ADB damage to provenances of F. excelsior sourced from throughout the British Isles was planted in 2013 in the southeast of England. In 2016, we scored trees by their level of ADB damage observed in field at the two worst affected (based on assessments in 2015) of the 14 sites. Significant differences were found in average ADB damage among planting sites and seed source provenances. Trees from certain provenances in Scotland were the least damaged by ADB, whereas trees from Wales and Southeast England were the most badly damaged in both trial sites. Thus the levels of ADB damage currently seen in ash populations in Southeast England may not be an accurate predictor of the damage expected in future throughout the British Isles. Given all provenances contained some healthy trees, a breeding programme to produce genetically variable native ash tree populations with lower ADB susceptibility may be feasible. PMID- 29185458 TI - Reactive molecular dynamic simulations on the gas separation performance of porous graphene membrane. AB - The separation of gases molecules with similar diameter and shape is an important area of research. For example, the major challenge to set up sweeping carbon dioxide capture and storage (CCS) in power plants is the energy requisite to separate the CO2 from flue gas. Porous graphene has been proposed as superior material for highly selective membranes for gas separation. Here we design some models of porous graphene with different sizes and shape as well as employ double layers porous graphene for efficient CO2/H2 separation. The selectivity and permeability of gas molecules through various nanopores were investigated by using the reactive molecular dynamics simulation which considers the bond forming/breaking mechanism for all atoms. Furthermore, it uses a geometry dependent charge calculation scheme that accounts appropriately for polarization effect which can play an important role in interacting systems. It was found that H-modified porous graphene membrane with pore diameter (short side) of about 3.75 A has excellent selectivity for CO2/H2 separation. The mechanism of gas penetration through the sub-nanometer pore was presented for the first time. The accuracy of MD simulation results validated by valuable DFT method. The present findings show that reactive MD simulation can propose an economical means of separating gases mixture. PMID- 29185459 TI - Analysis and correction of errors in nanoscale particle tracking using the Single pixel interior filling function (SPIFF) algorithm. AB - Particle tracking, which is an essential tool in many fields of scientific research, uses algorithms that retrieve the centroid of tracked particles with sub-pixel accuracy. However, images in which the particles occupy a small number of pixels on the detector, are in close proximity to other particles or suffer from background noise, show a systematic error in which the particle sub-pixel positions are biased towards the center of the pixel. This "pixel locking" effect greatly reduces particle tracking accuracy. In this report, we demonstrate the severity of these errors by tracking experimental (and simulated) imaging data of optically trapped silver nanoparticles and single fluorescent proteins. We show that errors in interparticle separation, angle and mean square displacement are significantly reduced by applying the corrective Single-Pixel Interior Filling Function (SPIFF) algorithm. Our work demonstrates the potential ubiquity of such errors and the general applicability of SPIFF correction to many experimental fields. PMID- 29185460 TI - Reprogramming to pluripotency does not require transition through a primitive streak-like state. AB - Pluripotency can be induced in vitro from adult somatic mammalian cells by enforced expression of defined transcription factors regulating and initiating the pluripotency network. Despite the substantial advances over the last decade to improve the efficiency of direct reprogramming, exact mechanisms underlying the conversion into the pluripotent stem cell state are still vaguely understood. Several studies suggested that induced pluripotency follows reversed embryonic development. For somatic cells of mesodermal and endodermal origin that would require the transition through a Primitive streak-like state, which would necessarily require an Eomesodermin (Eomes) expressing intermediate. We analyzed reprogramming in human and mouse cells of mesodermal as well as ectodermal origin by thorough marker gene analyses in combination with genetic reporters, conditional loss of function and stable fate-labeling for the broad primitive streak marker Eomes. We unambiguously demonstrate that induced pluripotency is not dependent on a transient primitive streak-like stage and thus does not represent reversal of mesendodermal development in vivo. PMID- 29185461 TI - Data driven inference for the repulsive exponent of the Lennard-Jones potential in molecular dynamics simulations. AB - The Lennard-Jones (LJ) potential is a cornerstone of Molecular Dynamics (MD) simulations and among the most widely used computational kernels in science. The LJ potential models atomistic attraction and repulsion with century old prescribed parameters (q = 6, p = 12, respectively), originally related by a factor of two for simplicity of calculations. We propose the inference of the repulsion exponent through Hierarchical Bayesian uncertainty quantification We use experimental data of the radial distribution function and dimer interaction energies from quantum mechanics simulations. We find that the repulsion exponent p ~ 6.5 provides an excellent fit for the experimental data of liquid argon, for a range of thermodynamic conditions, as well as for saturated argon vapour. Calibration using the quantum simulation data did not provide a good fit in these cases. However, values p ~ 12.7 obtained by dimer quantum simulations are preferred for the argon gas while lower values are promoted by experimental data. These results show that the proposed LJ 6-p potential applies to a wider range of thermodynamic conditions, than the classical LJ 6-12 potential. We suggest that calibration of the repulsive exponent in the LJ potential widens the range of applicability and accuracy of MD simulations. PMID- 29185462 TI - Histopathological, immunohistochemical, and ultrastructural evidence of spontaneous Senecavirus A-induced lesions at the choroid plexus of newborn piglets. AB - Epidemic Transient Neonatal Losses (ETNL) is a disease of piglets caused by Senecavirus A (SVA) in which the method of dissemination and associated lesions are not well-defined. This study investigated the possible SVA-induced lesions by examining spontaneous infections in newborn piglets. Histopathology revealed ballooning degeneration of transitional epithelium, nonsuppurative meningoencephalitis, plexus choroiditis, and atrophic enteritis. RT-PCR identified SVA in all tissues evaluated and sequencing confirmed these results. Positive immunoreactivity to SVA was observed in endothelial and epithelial tissues of all organs evaluated. Semithin analysis revealed vacuolization of apical enterocytes of the small intestine, balloon degeneration and necrosis of endothelial cells of the choroid plexus (CP) and nonsuppurative choroid plexitis. Ultrathin evaluation demonstrated hydropic degeneration of apical enterocytes, degeneration and necrosis of endothelium of CP fenestrated capillaries, degeneration of ependymocytes associated with intralesional viral particles. It is proposed that SVA initially infects apical enterocytes of newborn piglets and probably enters the circulatory system with entry to the brain via the CP, by first producing an initial inflammatory reaction, with subsequent encephalitic dissemination. Consequently, SVA probably uses an enteric-neurological method of dissemination. PMID- 29185463 TI - IL-27, but not IL-35, inhibits neuroinflammation through modulating GM-CSF expression. AB - IL-27 and IL-35 are heterodimeric cytokines, members of the IL-12 family and considered to have immunomodulatory properties. Their role during neuroinflammation had been investigated using mutant mice devoid of either one of their subunits or lacking components of their receptors, yielding conflicting results. We sought to understand the therapeutic potential of IL-27 and IL-35 delivered by gene therapy in neuroinflammation. We constructed lentiviral vectors expressing IL-27 and IL-35 from a single polypeptide chain, and we validated in vitro their biological activity. We injected IL-27 and IL-35-expressing lentiviral vectors into the cerebrospinal fluid (CSF) of mice affected by experimental neuroinflammation (EAE), and performed clinical, neuropathological and immunological analyses. Both cytokines interfere with neuroinflammation, but only IL-27 significantly modulates disease development, both clinically and neuropathologically. IL-27 protects from autoimmune inflammation by inhibiting granulocyte macrophages colony-stimulating factor (GM-CSF) expression in CD4+ T cells and by inducing program death-ligand 1 (PD-L1) expression in both CNS resident and CNS-infiltrating myeloid cells. We demonstrate here that IL-27 holds therapeutic potential during neuroinflammation and that IL-27 inhibits GM-CSF and induces pd-l1 mRNA in vivo. PMID- 29185464 TI - Ripening-induced chemical modifications of papaya pectin inhibit cancer cell proliferation. AB - Papaya (Carica papaya L.) is a fleshy fruit with a rapid pulp softening during ripening. Ripening events are accompanied by gradual depolymerization of pectic polysaccharides, including homogalacturonans, rhamnogalacturonans, arabinogalactans, and their modified forms. During intermediate phases of papaya ripening, partial depolymerization of pectin to small size with decreased branching had enhanced pectin anti-cancer properties. These properties were lost with continued decomposition at later phases of ripening. Pectin extracted from intermediate phases of papaya ripening markedly decreased cell viability, induced necroptosis, and delayed culture wound closing in three types of immortalized cancer cell lines. The possible explanation for these observations is that papaya pectins extracted from the third day after harvesting have disrupted interaction between cancer cells and the extracellular matrix proteins, enhancing cell detachment and promoting apoptosis/necroptosis. The anticancer activity of papaya pectin is dependent on the presence and the branch of arabinogalactan type II (AGII) structure. These are first reports of AGII in papaya pulp and the first reports of an in vitro biological activity of papaya pectins that were modified by natural action of ripening-induced pectinolytic enzymes. Identification of the specific pectin branching structures presents a biological route to enhancing anti-cancer properties in papaya and other climacteric fruits. PMID- 29185465 TI - Probing spatial heterogeneity in silicon thin films by Raman spectroscopy. AB - Raman spectroscopy is a powerful technique for revealing spatial heterogeneity in solid-state structures but heretofore has not been able to measure spectra from multiple positions on a sample within a short time. Here, we report a novel Raman spectroscopy approach to study the spatial heterogeneity in thermally annealed amorphous silicon (a-Si) thin films. Raman spectroscopy employs both a galvano mirror and a two-dimensional charge-coupled device detector system, which can measure spectra at 200 nm intervals at every position along a sample in a short time. We analyzed thermally annealed a-Si thin films with different film thicknesses. The experimental results suggest a correlation between the distribution of the average nanocrystal size over different spatial regions and the thickness of the thermally annealed a-Si thin film. The ability to evaluate the average size of the Si nanocrystals through rapid data acquisition is expected to lead to research into new applications of nanocrystals. PMID- 29185466 TI - Macropis fulvipes Venom component Macropin Exerts its Antibacterial and Anti Biofilm Properties by Damaging the Plasma Membranes of Drug Resistant Bacteria. AB - The abuse of antibiotics for disease treatment has led to the emergence of multidrug resistant bacteria. Antimicrobial peptides, found naturally in various organisms, have received increasing interest as alternatives to conventional antibiotics because of their broad spectrum antimicrobial activity and low cytotoxicity. In a previous report, Macropin, isolated from bee venom, exhibited antimicrobial activity against both gram-positive and negative bacteria. In the present study, Macropin was synthesized and its antibacterial and anti-biofilm activities were tested against bacterial strains, including gram-positive and negative bacteria, and drug resistant bacteria. Moreover, Macropin did not exhibit hemolytic activity and cytotoxicity to keratinocytes, whereas Melittin, as a positive control, showed very high toxicity. Circular dichroism assays showed that Macropin has an alpha-helical structure in membrane mimic environments. Macropin binds to peptidoglycan and lipopolysaccharide and kills the bacteria by disrupting their membranes. Moreover, the fractional inhibitory concentration index indicated that Macropin has additive and partially synergistic effects with conventional antibiotics against drug resistant bacteria. Thus, our study suggested that Macropin has potential for use of an antimicrobial agent for infectious bacteria, including drug resistant bacteria. PMID- 29185467 TI - Phylogeography reveals a potential cryptic invasion in the Southern Hemisphere of Ceratophyllum demersum, New Zealand's worst invasive macrophyte. AB - Ceratophyllum demersum (common hornwort) is presently considered the worst invasive submerged aquatic macrophyte in New Zealand. We explored the global phylogeographic pattern of the species, based on chloroplast and nuclear DNA, in order to identify the origin of the invasive populations in New Zealand and to clarify if there were multiple introductions. The phylogeographic study identified geographically differentiated gene pools in North America, tropical Asia, Australia, and South Africa, likely native to these regions, and a recent dispersal event of a Eurasian-related haplotype to North America, New Zealand, Australia, and South Africa. At least two different invasive genotypes of this Eurasian-related haplotype have been found in New Zealand. One genotype is closely related to genotypes in Australia and South Africa, while we could not trace the closest relatives of the other genotype within our C. demersum sample set. Contrasting spectra of genetic distances in New Zealand and in a region within the native range (Denmark), suggest that the invasive population was founded by vegetative reproduction, seen as low genetic distances among genotypes. We also discovered the introduction of the same Eurasian-related haplotype in Australia and South Africa and that a cryptic invasion may be occurring in these continents. PMID- 29185468 TI - Consistency and flexibility in solving spatial tasks: different horses show different cognitive styles. AB - Individual animals vary in their behaviour and reactions to novel situations. These differences may extend to differences in cognition among individuals. We tested twenty-six horses for their ability to detour around symmetric and asymmetric obstacles. All of the animals were able to get around the barrier to reach a food target, but varied in their approach. Some horses moved slowly but were more accurate in choosing the shortest way. Other horses acted quickly, consistently detoured in the same direction, and did not reliably choose the shortest way. The remaining horses shifted from a faster, directionally consistent response with the symmetric barrier, to a slower but more accurate response with the asymmetric barrier. The asymmetric barrier induced a reduction in heart rate variability, suggesting that this is a more demanding task. The different approaches used to solve the asymmetric task may reflect distinct cognitive styles in horses, which vary among individuals, and could be linked to different personality traits. Understanding equine behaviour and cognition can inform horse welfare and management. PMID- 29185469 TI - Transformation of Organostannanes Based on Photocleavage of C-Sn Bond via Single Electron Transfer Process. AB - In this work, we developed a new method for the transformation of organostannanes via radical process. In this reaction, highly reactive carbon radical species can be efficiently generated through HBr-catalyzed photocleavage of C-Sn bond via single electron transfer process. Under aerobic conditions, the in situ formed primary/secondary alkyl radicals can be further highly selectively oxidized into carboxylic acids/ketones, respectively. PMID- 29185470 TI - All-dielectric polarization-independent optical angular filter. AB - We report on an all-dielectric, polarization-independent angular filter with one dimension (1D) photonic crystal (PC) composed of semiconductor compatible Si/SiO2 pairs. The near-symmetric directional band gap of p- and s-polarized components and Fabry-Perot (F-P) resonances are utilized to realize efficient polarization independent angular filtering for normal incidence. The proposed angular filter is designed and experimentally demonstrated in a large area (5 cm * 5 cm) with multilayer sputtering depositions. Experimental measurements show that a divergence angle of the polarization-independently transmitted beam through the angular filtering sample at 1550 nm is 2.2 degrees only and the transmission is as high as 0.8 at normal incidence. The proposed and demonstrated angular filter suggests an effective way to design and implement semiconductor compatible, all dielectric and polarization-independent angular filters in a fashion of simple structure and easy-fabrication, which is expected to have great applications in lighting, beam manipulation, optical coupling and optical communications. PMID- 29185471 TI - Capsize of polarization in dilute photonic crystals. AB - We investigate, experimentally and theoretically, polarization rotation effects in dilute photonic crystals with transverse permittivity inhomogeneity perpendicular to the traveling direction of waves. A capsize, namely a drastic change of polarization to the perpendicular direction is observed in a one dimensional photonic crystal in the frequency range 10 / 140 GHz. To gain more insights into the rotational mechanism, we have developed a theoretical model of dilute photonic crystal, based on Maxwell's equations with a spatially dependent two dimensional inhomogeneous dielectric permittivity. We show that the polarization's rotation can be explained by an optical splitting parameter appearing naturally in Maxwell's equations for magnetic or electric fields components. This parameter is an optical analogous of Rashba like spin-orbit interaction parameter present in quantum waves, introduces a correction to the band structure of the two-dimensional Bloch states, creates the dynamical phase shift between the waves propagating in the orthogonal directions and finally leads to capsizing of the initial polarization. Excellent agreement between theory and experiment is found. PMID- 29185472 TI - Computational and NMR spectroscopy insights into the conformation of cyclic di nucleotides. AB - Cyclic di-nucleotides (CDNs) are second messengers in bacteria and metazoan that are as such controlling important biological processes. Here the conformational space of CDNs was explored systematically by a combination of extensive conformational search and DFT calculations as well as NMR methods. We found that CDNs adopt pre-organized conformations in solution in which the ribose conformations are North type and glycosidic bond conformations are anti type. The overall flexibility of CDNs as well as the backbone torsion angles depend on the cyclization of the phosphodiester bond. Compared to di-nucleotides, CDNs display high rigidity in the macrocyclic moieties. Structural comparison studies demonstrate that the pre-organized conformations of CDNs highly resemble the biologically active conformations. These findings provide information for the design of small molecules to modulate CDNs signalling pathways in bacteria or as vaccine adjuvants. The rigidity of the backbone of CDNs enables the design of high order structures such as molecular cages based on CDNs analogues. PMID- 29185473 TI - The Systemic Response to Topical Aldara Treatment is Mediated Through Direct TLR7 Stimulation as Imiquimod Enters the Circulation. AB - Topical application of Aldara cream, containing the Toll-like receptor 7/8 agonist Imiquimod, is a widely used mouse model for investigating the pathogenesis of psoriasis. We have previously used this model to study the effects of peripheral inflammation on the brain, and reported a brain-specific response characterised by increased transcription, infiltration of immune cells and anhedonic-like behavior. Here, we perform a more robust characterisation of the systemic response to Aldara application and find a potent but transient response in the periphery, followed by a prolonged response in the brain. Mass spectrometry analysis of plasma and brain samples identified significant levels of Imiquimod in both compartments at molar concentrations likely to evoke a biological response. Indeed, the association of Imiquimod with the brain correlated with increased Iba1 and GFAP staining, indicative of microglia and astrocyte reactivity. These results highlight the potency of this model and raise the question of how useful it is for interpreting the systemic response in psoriasis-like skin inflammation. In addition, the potential impact on the brain should be considered with regards to human use and may explain why fatigue, headaches and nervousness have been reported as side effects following prolonged Aldara use. PMID- 29185474 TI - Exploration of Hand Grasp Patterns Elicitable Through Non-Invasive Proximal Nerve Stimulation. AB - Various neurological conditions, such as stroke or spinal cord injury, result in an impaired control of the hand. One method of restoring this impairment is through functional electrical stimulation (FES). However, traditional FES techniques often lead to quick fatigue and unnatural ballistic movements. In this study, we sought to explore the capabilities of a non-invasive proximal nerve stimulation technique in eliciting various hand grasp patterns. The ulnar and median nerves proximal to the elbow joint were activated transcutanously using a programmable stimulator, and the resultant finger flexion joint angles were recorded using a motion capture system. The individual finger motions averaged across the three joints were analyzed using a cluster analysis, in order to classify the different hand grasp patterns. With low current intensity (<5 mA and 100 us pulse width) stimulation, our results show that all of our subjects demonstrated a variety of consistent hand grasp patterns including single finger movement and coordinated multi-finger movements. This study provides initial evidence on the feasibility of a proximal nerve stimulation technique in controlling a variety of finger movements and grasp patterns. Our approach could also be developed into a rehabilitative/assistive tool that can result in flexible movements of the fingers. PMID- 29185475 TI - Transcriptome Analysis of Two Species of Jute in Response to Polyethylene Glycol (PEG)- induced Drought Stress. AB - Drought stress results in significant crop yield losses. Comparative transcriptome analysis between tolerant and sensitive species can provide insights into drought tolerance mechanisms in jute. We present a comprehensive study on drought tolerance in two jute species-a drought tolerant species (Corchorus olitorius L., GF) and a drought sensitive species (Corchorus capsularis L., YY). In total, 45,831 non-redundant unigenes with average sequence length of 1421 bp were identified. Higher numbers of differentially expressed genes (DEGs) were discovered in YY (794) than in GF (39), implying that YY was relatively more vulnerable or hyper-responsive to drought stress at the molecular level; the two main pathways, phenylpropanoid biosynthesis and peroxisome pathway, significantly involved in scavenging of reactive oxygen species (ROS) and 14 unigenes in the two pathways presented a significant differential expression in response to increase of superoxide. Our classification analysis showed that 1769 transcription factors can be grouped into 81 families and 948 protein kinases (PKs) into 122 families. In YY, we identified 34 TF DEGs from and 23 PK DEGs, including 19 receptor-like kinases (RLKs). Most of these RLKs were downregulated during drought stress, implying their role as negative regulators of the drought tolerance mechanism in jute. PMID- 29185476 TI - Fine platinum nanoparticles supported on a porous ceramic membrane as efficient catalysts for the removal of benzene. AB - It would be desirable to remove volatile organic compounds (VOCs) while we eliminate the dusts using silicon carbide (SiC)-based porous ceramics from the hot gases. Aiming at functionalizing SiC-based porous ceramics with catalytic capability, we herein report a facile strategy to integrate high efficient catalysts into the porous SiC substrates for the VOC removal. We demonstrate an aqueous salt method for uniformly distributing fine platinum (Pt) particles on the alumina (Al2O3) layers, which are pre-coated on the SiC substrates as supports for VOC catalysts. We confirm that at a Pt mass loading as low as 0.176% and a weight hourly space velocity of 6000 mL g-1 h-1, the as-prepared Pt/SiC@Al2O3 catalysts can convert 90% benzene at a temperature of ca. 215 degrees C. The results suggest a promising way to design ceramics-based bi functional materials for simultaneously eliminating dusts and harmful VOCs from various hot gases.

AB - A method is proposed for efficient laser modification of fused silica and sapphire by means of a burst of femtosecond pulses having time separation in the range 10-3000 ps. Modification enhancement with the pulse separation increase in the burst was observed on the tens picoseconds scale. It is proposed that accumulated transient tensile strain in the excitation region plays a crucial role in modification by a sub-nanosecond burst. PMID- 29185478 TI - Charge-state Resolved Infrared Multiple Photon Dissociation (IRMPD) Spectroscopy of Ubiquitin Ions in the Gas Phase. AB - In this study, we obtained for the first time the direct infrared multiple photon dissociation (IRMPD) spectra of ubiquitin ions in the range 2700-3750 cm-1. Ubiquitin ions with different charge states showed absorption in the two regions of 2940-3000 cm-1 and 3280-3400 cm-1. The increase of the charge state of ubiquitin ions broadened the absorption peak on the high-frequency side in the second region, indicating some hydrogen bonds were weakened due to Coulomb interaction. It is also found that the relative intensity of the absorption peak in the first region compared to the absorption peak in the second region increased with increasing charge state, making the IRMPD spectra charge-state resolved. Although it is usually reasonable to suggest the origin of the absorption in the range 2940-3000 cm-1 as the C-H bond stretching modes, the results show significantly reduced absorption after the deuteration of all labile hydrogen atoms. A possible explanation for this is that the coupling coefficients between the C-H vibrational mode and other selective modes decreased greatly after the deuteration, reducing the rate of energy redistribution and probability of consecutive IR absorption. PMID- 29185479 TI - Characterising Pre-pubertal Resistance to Death from Endotoxemia. AB - Sepsis is a common and deadly syndrome in which a dysregulated host response to infection causes organ failure and death. The current lack of treatment options suggests that a new approach to studying sepsis is needed. Pre-pubertal children show a relative resistance to death from severe infections and sepsis. To explore this phenomenon experimentally, we used an endotoxemia model of sepsis in mice. Following intra-peritoneal injection of endotoxin, pre-pubertal mice showed greater survival than post-pubertal mice (76.3% vs. 28.6%), despite exhibiting a similar degree of inflammation after two hours. Age-associated differences in the inflammatory response only became evident at twenty hours, when post-pubertal mice showed prolonged elevation of serum cytokines and differential recruitment of peritoneal immune cells. Mechanistically, prevention of puberty by hormonal blockade or acceleration of puberty by oestrogen treatment led to increased or decreased survival from endotoxemia, respectively. Additionally, the adoptive transfer of pre-pubertal peritoneal cells improved the survival of post-pubertal recipient mice, while post-pubertal peritoneal cells or vehicle did not. These data establish a model for studying childhood resistance to mortality from endotoxemia, demonstrate that oestrogen is responsible for an increased susceptibility to mortality after puberty, and identify peritoneal cells as mediators of pre-pubertal resistance. PMID- 29185480 TI - Initial Cross-Over Test of A Positive Allosteric Modulator of Alpha-7 Nicotinic Receptors to Aid Cessation in Smokers With Or Without Schizophrenia. AB - Preclinical research shows that compounds acting at alpha7 nicotinic receptors (nAChRs) can reduce nicotine self-administration, suggesting that a positive allosteric modulator (PAM) of alpha7 receptors, JNJ-39393406, may aid smoking cessation. Moreover, individuals with schizophrenia, who have very high rates of smoking, have reduced expression of alpha7 nAChRs and may particularly benefit from this compound. In two parallel studies using a within-subject cross-over design, 36 healthy smokers (Study 1) and 62 smokers with schizophrenia (Study 2), both groups high in quit interest, attempted to initiate quitting temporarily during each of two 3-week phases. Treatments were the alpha7 nicotinic receptor PAM JNJ-39393406 (100 mg b.i.d.) or placebo (double-blind, counter-balanced). In each phase, all smoked ad lib with no drug on week 1 or during dose run-up on week 2, and then tried to quit every day during week 3. Abstinence (confirmed by CO <5 p.p.m.) and smoking reduction (CO <8), as well as cigarettes/day (in Study 1), were assessed daily (Monday-Friday) each quit week and compared between conditions. Secondary outcomes included abstinence symptoms (withdrawal and craving) and cognitive test responding (N-back; continuous performance task). In both studies, compared with placebo, active JNJ-39393406 did not increase the number of abstinent days nor reduce total smoking exposure. We also found no significant improvements in craving, withdrawal, or cognitive function. With this dose and study duration, our findings do not support further testing of this alpha7 nAChR PAM compound for possible efficacy in smoking cessation, in smokers with or without schizophrenia. PMID- 29185481 TI - Methamphetamine Induces Dopamine Release in the Nucleus Accumbens Through a Sigma Receptor-Mediated Pathway. AB - Methamphetamine (METH) is a drug with a high addictive potential that is widely abused across the world. Although it is known that METH dysregulates both dopamine transmission and dopamine reuptake, the specific mechanism of action remains obscure. One promising target of METH is the sigma receptor, a chaperone protein located on the membrane of the endoplasmic reticulum. Using fast-scan cyclic voltammetry, we show that METH-enhancement of evoked dopamine release and basal efflux is dependent on sigma receptor activation. METH-induced activation of sigma receptors results in oxidation of a cysteine residue on VMAT2, which decreases transporter function. Unilateral injections of the sigma receptor antagonist BD-1063 prior to METH administration increased dopamine-related ipsilateral circling behavior, indicating the involvement of sigma receptors. These findings suggest that interactions between METH and the sigma receptor lead to oxidative species (most likely superoxide) that in turn oxidize VMAT2. Altogether, these findings show that the sigma receptor has a key role in METH dysregulation of dopamine release and dopamine-related behaviors.

The role of prostaglandin transporter OATP2A1/SLCO2A1 in colon cancer tumorogenesis is unknown. We evaluated mice of various Slco2a1 genotypes in a murine model of colon cancer, the adenomatous polyposis (APC) mutant (Apc ?716/+) model. Median lifespan was significantly extended from 19 weeks in Slco2a1 +/+/Apc Delta716/+ mice to 25 weeks in Slco2a1 -/-/Apc Delta716/+ mice. Survival was directly related to a reduction in the number of large polyps in the Slco2a1 -/- /Apc ?716/+ compared to the Slco2a1 +/+/Apc Delta716/+ or Slco2a1 +/-/Apc Delta716/+mice. The large polyps from the Slco2a1 /- /Apc ?716/+ mice had significant reductions in microvascular density, consistent with the high expression of Slco2a1 in the tumour-associated vascular endothelial cells. Chemical suppression of OATP2A1 function significantly reduced tube formation and wound-healing activity of PGE2 in human vascular endothelial cells (HUVECs) although the amount of extracellular PGE2 was not affected by an OATP2A1 inhibitor. Further an in vivo model of angiogenesis, showed a significant reduction of haemoglobin content (54.2%) in sponges implanted into Slco2a1 -/-, compared to wildtype mice. These studies indicate that OATP2A1 is likely to promote tumorogenesis by PGE2 uptake into the endothelial cells, suggesting that blockade of OATP2A1 is an additional pharmacologic strategy to improve colon cancer outcomes. PMID- 29185483 TI - Impact of Mismatch Angle on Electronic Transport Across Grain Boundaries and Interfaces in 2D Materials. AB - We study the impact of grain boundaries (GB) and misorientation angles between grains on electronic transport in 2-dimensional materials. Here we have developed a numerical model based on the first-principles electronic bandstructure calculations in conjunction with a method which computes electron transmission coefficients from simultaneous conservation of energy and momentum at the interface to essentially evaluate GB/interface resistance in a Landauer formalism. We find that the resistance across graphene GBs vary over a wide range depending on misorientation angles and type of GBs, starting from 53 Omega MUm for low-mismatch angles in twin (symmetric) GBs to about 1020 Omega MUm for 21 degrees mismatch in tilt (asymmetric) GBs. On the other hand, misorientation angles have weak influence on the resistance across MoS2 GBs, ranging from about 130 Omega MUm for low mismatch angles to about 6000 Omega MUm for 21 degrees . The interface resistance across graphene-MoS2 heterojunctions also exhibits a strong dependence on misorientation angles with resistance values ranging from about 100 Omega MUm for low-mismatch angles in Class-I (symmetric) interfaces to 1015 Omega MUm for 14 degrees mismatch in Class-II (asymmetric) interfaces. Overall, symmetric homo/heterojunctions exhibit a weak dependence on misorientation angles, while in MoS2 both symmetric and asymmetric GBs show a gradual dependence on mismatch angles.

AB - The crystal grain size of CH3NH3PbI3 (MAPbI3) organic-inorganic hybrid perovskite (OHP) film was controllable in the range from ~60 nm to ~600 nm by non-solvents inter-diffusion controlled crystallization process in dripping crystallization method for the formation of perovskite film. The MAPbI3 OHP non-volatile resistive random access memory with ~60 nm crystal grain size exhibited >0.1 TB/in2 storage capacity, >600 cycles endurance, >104 s data retention time, ~0.7 V set, and ~-0.61 V re-set bias voltage. PMID- 29185485 TI - Strong localization of oxidized Co3+ state in cobalt-hexacyanoferrate. AB - Secondary batteries are important energy storage devices for a mobile equipment, an electric car, and a large-scale energy storage. Nevertheless, variation of the local electronic state of the battery materials in the charge (or oxidization) process are still unclear. Here, we investigated the local electronic state of cobalt-hexacyanoferrate (Na x Co[Fe(CN)6]0.9), by means of resonant inelastic X ray scattering (RIXS) with high energy resolution (~100 meV). The L-edge RIXS is one of the most powerful spectroscopic technique with element- and valence selectivity. We found that the local electronic state around Co2+ in the partially-charged Na1.1Co2+0.5Co3+0.5[Fe2+(CN)6]0.9 film (x = 1.1) is the same as that of the discharged Na1.6Co2+[Fe2+(CN)6]0.9 film (x = 1.6) within the energy resolution, indicating that the local electronic state around Co2+ is invariant against the partial oxidization. In addition, the local electronic state around the oxidized Co3+ is essentially the same as that of the fully-charged film Co3+[Fe2+(CN)6]0.3[Fe3+(CN)6]0.6 (x = 0.0) film. Such a strong localization of the oxidized Co3+ state is advantageous for the reversibility of the redox process, since the localization reduces extra reaction within the materials and resultant deterioration. PMID- 29185486 TI - Metabolomics profiling reveals different patterns in an animal model of asphyxial and dysrhythmic cardiac arrest. AB - Cardiac arrest (CA) is not a uniform condition and its pathophysiology strongly depends on its cause. In this work we have used a metabolomics approach to study the dynamic metabolic changes occurring in the plasma samples of a swine model following two different causes of CA, namely asphyxia (ACA) and ventricular fibrillation (VFCA). Plasma samples were collected at baseline and every minute during the experimental phases. In order to identify the metabolomics profiles characterizing the two pathological entities, all samples were analysed by 1H NMR spectroscopy and LC-MS/MS spectrometry.The metabolomics fingerprints of ACA and VFCA significantly differed during the peri-arrest period and the resuscitation phase. Major alterations were observed in plasma concentrations of metabolites related to tricarboxylic acid (TCA) cycle, urea cycle, and anaplerotic replenishing of TCA. ACA animals showed significant metabolic disturbances during the asphyxial and CA phases, while for VFCA animals this phenomenon resulted shifted at the resuscitation phase. Interestingly, starting from the asphyxial phase, the ACA animals were stratified in two groups based on their metabolomics profiles that resulted to be correlated with the clinical outcome. Succinate overproduction was observed in the animals with the worse outcome, suggesting a potential prognostic role for this metabolite. PMID- 29185487 TI - Cross-reactivity of antibodies against interferon beta in multiple sclerosis patients and interference of the JAK-STAT signaling pathway. AB - Interferon beta (IFNbeta) therapy has immunogenic properties and induces the development of neutralizing antibodies (NAbs). From the extensive literature focused in the development of NAbs in multiple sclerosis (MS) patients, their ability to cross-react has been deficiently evaluated, despite having important consequences in the clinical practice. Here, the relation between the cross reactivity and the NAbs titers has been evaluated in MS patients, by inhibition of the antiviral activity of IFNbeta by bioassay and through the interference with the activation of the IFNbeta pathway (JAK-STAT), by phosphoflow. Thus, patients with intermediate-high titers of NAbs, determined by bioassay, had a 79 fold increased risk of cross-reactivity compared to patients with low titers. The cross-reactivity is also demonstrated because NAbs positive sera were able to decrease significantly the activation of pSTAT1 achieved by other different IFNbeta molecules in the cells patients. Besides, a linear relationship between the STAT1 phosphorylation and NAbs titers was found. The study demonstrates that cross-reactivity increases with the titer of antibodies, which has important implications in clinical practice when switching the treatment. The direct relationship between the NAbs titer and the activation of STAT1 suggest that its determination could be an indirect method to identify the presence of NAbs. PMID- 29185488 TI - MicroRNA regulation of Transthyretin in trophoblast differentiation and Intra Uterine Growth Restriction. AB - Placental trophoblast cells produce various cytokines, transporters vital to normal embryogenesis. Transthyretin (TTR) aids trans-placental passage of maternal thyroxin (TH) to fetal circulation. Inadequate TH delivery leads to developmental abnormality. Regulation of TTR biosynthesis in placenta is critical for normal embryo development. We showed here that TTR transcripts were expressed more in fetal placenta. Using bioinformatic analysis and confirmation with dual luciferase reporter assays, we found that miR-200a-3p and miR-141-3p inhibited TTR expression by directly binding to the 3'UTR of TTR, which is reversed by mutation in the microRNA binding site. Differentiation of human trophoblast BeWo cells was associated with decreased TTR transcript and protein levels with concomitant increase in the levels of both microRNAs. Interestingly, ectopic overexpression of the microRNA mimics abrogated thyroxin uptake by BeWo cells, which was reversed by the corresponding inhibitors. Furthermore, in a rat model of intra-uterine growth restriction (IUGR), TTR expression decreased significantly in placenta with reciprocal rise in miR-141-3p but not 200a-3p. In human IUGR placenta, TTR transcript and protein levels were significantly lower associated with high expression of miR-141-3p but not 200a-3p. These data provides new insight into physiological role of miR-141-3p in regulating TTR during trophoblast differentiation and IUGR. PMID- 29185489 TI - Risk of mortality during and after the 2011 Great East Japan Earthquake and Tsunami among older coastal residents. AB - The Japan Gerontological Evaluation Study is a nationwide cohort study of individuals aged 65 years and older established in July 2010. Seven months later, one of the study field sites was directly in the line of the 2011 Great East Japan Earthquake and Tsunami. Despite the 1-hour warning interval between the earthquake and tsunami, many coastal residents lost their lives. We analyzed the risk of all-cause mortality on the day of the disaster as well as in the 38-month interval after the disaster. Among 860 participants, 33 (3.8%) died directly because of the tsunami and an additional 95 people died during the 38-month follow-up period. Individuals with depressive symptoms had elevated risk of mortality on the day of the disaster (odds ratio = 3.90 [95% CI: 1.13, 13.47]). More socially connected people also suffered increased risk of mortality, although these estimates were not statistically significant. In contrast, after the disaster, frequent social interactions reverted back to predicting improved survival (hazard ratio = 0.46 (95% CI: 0.26, 0.82)). Depressive symptoms and stronger social connectedness were associated with increased risk of mortality on the day of the disaster. After the disaster, social interactions were linked to improved survival. PMID- 29185491 TI - Observability of Complex Systems: Finding the Gap. AB - For a reconstruction of state and parameter values in a dynamic system model, first the question whether these values can be uniquely determined from the data must be answered. This structural model property is known as observability or, in case of parameter calibration only, identifiability. Testing a given model for observability is a well studied problem in the systems and control sciences. However, it is increasingly difficult, if not impossible, to address this property for large size models that, nowadays, are frequently used. We demonstrate the application of a recently developed algorithm that overcomes this problem and is remarkably efficient. As an illustration we show how an observability analysis for a Chinese Hamster Ovary Cell model (34 states, 117 parameters), a JAKSTAT signalling model (31 states, 51 parameters), and a MAP Kinase model (100 states, 88 parameters) can be established in a very short time. PMID- 29185490 TI - Aberrant brain response after auditory deviance in PTSD compared to trauma controls: An EEG study. AB - Part of the symptomatology of post-traumatic stress disorder (PTSD) are alterations in arousal and reactivity which could be related to a maladaptive increase in the automated sensory change detection system of the brain. In the current EEG study we investigated whether the brain's response to a simple auditory sensory change was altered in patients with PTSD relative to trauma exposed matched controls who did not develop the disorder. Thirteen male PTSD patients and trauma-exposed controls matched for age and educational level were presented with regular auditory pure tones (1000 Hz, 200 ms duration), with 11% of the tones deviating in both duration (50 ms) and frequency (1200 Hz) while watching a silent movie. Relative to the controls, patients who had developed PTSD showed enhanced mismatch negativity (MMN), increased theta power (5-7 Hz), and stronger suppression of upper alpha activity (13-15 Hz) after deviant vs. standard tones. Behaviourally, the alpha suppression in PTSD correlated with decreased spatial working memory performance suggesting it might reflect enhanced stimulus-feature representations in auditory memory. These results taken together suggest that PTSD patients and trauma-exposed controls can be distinguished by enhanced involuntary attention to changes in sensory patterns. PMID- 29185492 TI - Interaction profiling of RNA-binding ubiquitin ligases reveals a link between posttranscriptional regulation and the ubiquitin system. AB - RNA-binding ubiquitin ligases (RBULs) have the potential to link RNA-mediated mechanisms to protein ubiquitylation. Despite this, the cellular functions, substrates and interaction partners of most RBULs remain poorly characterized. Affinity purification (AP) combined with quantitative mass spectrometry (MS) based proteomics is a powerful approach for analyzing protein functions. Mapping the physiological interaction partners of RNA-binding proteins has been hampered by their intrinsic properties, in particular the existence of low-complexity regions, which are prone to engage in non-physiological interactions. Here, we used an adapted AP approach to identify the interaction partners of human RBULs harboring different RNA-binding domains. To increase the likelihood of recovering physiological interactions, we combined control and bait-expressing cells prior to lysis. In this setup, only stable interactions that were originally present in the cell will be identified. We exploit gene function similarity between the bait proteins and their interactors to benchmark our approach in its ability to recover physiological interactions. We reveal that RBULs engage in stable interactions with RNA-binding proteins involved in different steps of RNA metabolism as well as with components of the ubiquitin conjugation machinery and ubiquitin-binding proteins. Our results thus demonstrate their capacity to link posttranscriptional regulation with the ubiquitin system. PMID- 29185493 TI - On-chip integrated vertically aligned carbon nanotube based super- and pseudocapacitors. AB - On-chip energy storage and management will have transformative impacts in developing advanced electronic platforms with built-in energy needs for operation of integrated circuits driving a microprocessor. Though success in growing stand alone energy storage elements such as electrochemical capacitors (super and pseusocapacitors) on a variety of substrates is a promising step towards this direction. In this work, on-chip energy storage is demonstrated using architectures of highly aligned vertical carbon nanotubes (CNTs) acting as supercapacitors, capable of providing large device capacitances. The efficiency of these structures is further increased by incorporating electrochemically active nanoparticles such as MnOx to form pseudocapacitive architectures thus enhancing device capacitance areal specific capacitance of 37 mF/cm2. The demonstrated on-chip integration is up and down-scalable, compatible with standard CMOS processes, and offers lightweight energy storage what is vital for portable and autonomous device operation with numerous advantages as compared to electronics built from discrete components. PMID- 29185494 TI - Performance enhancement of a brain-computer interface using high-density multi distance NIRS. AB - This study investigated the effectiveness of using a high-density multi-distance source-detector (SD) separations in near-infrared spectroscopy (NIRS), for enhancing the performance of a functional NIRS (fNIRS)-based brain-computer interface (BCI). The NIRS system that was used for the experiment was capable of measuring signals from four SD separations: 15, 21.2, 30, and 33.5 mm, and this allowed the measurement of hemodynamic response alterations at various depths. Fifteen participants were asked to perform mental arithmetic and word chain tasks, to induce task-related hemodynamic response variations, or they were asked to stay relaxed to acquire a baseline signal. To evaluate the degree of BCI performance enhancement by high-density channel configuration, the classification accuracy obtained using a typical low-density lattice SD arrangement, was compared to that obtained using the high-density SD arrangement, while maintaining the SD separation at 30 mm. The analysis results demonstrated that the use of a high-density channel configuration did not result in a noticeable enhancement of classification accuracy. However, the combination of hemodynamic variations, measured by two multi-distance SD separations, resulted in the significant enhancement of overall classification accuracy. The results of this study indicated that the use of high-density multi-distance SD separations can likely provide a new method for enhancing the performance of an fNIRS-BCI. PMID- 29185495 TI - Impact of customary fluoride rinsing solutions on the pellicle's protective properties and bioadhesion in situ. AB - This study investigated the impact of customary fluoride based mouthrinses on the ultrastructure and the functional properties of the in situ pellicle, considering the prevention of erosion (8 volunteers) and initial biofilm formation (12 volunteers). Bovine enamel slabs were carried intraorally. After 1 min of pellicle formation, the subjects rinsed with elmex Kariesschutz (A), Dontodent Med Care (B), meridol (C) or elmex Zahnschmelzschutz Professional (D) for 1 min. In situ pellicle formation was continued up to 30 min/8 h before processing the slabs in vitro. Erosion was simulated by incubating the specimens in HCl (pH 3.0, 2.3, 2.0) for 120 s, measuring the kinetics of calcium/phosphate release photometrically; representative samples were evaluated by TEM and EDX. Bacterial adhesion was visualized fluorescence microscopically (DAPI/BacLight). Native enamel slabs or physiological pellicle samples served as controls. All investigated mouthrinses enhanced the erosion preventive pellicle effect in dependence of the pH-value. A significant decrease of Ca/P release at all pH values was achieved after rinsing with D; TEM/EDX confirmed ultrastructural pellicle modifications. All mouthrinses tendentially reduced bacterial adherence, however not significantly. The mouthrinse containing NaF/AmF/SnCl2 (D) offers an effective oral hygiene supplement to prevent caries and erosion. PMID- 29185497 TI - High throughput deep sequencing reveals the important roles of microRNAs during sweetpotato storage at chilling temperature. AB - Sweetpotato (Impomoea batatas L.) is a globally important economic food crop with a potential of becoming a bioenergy and pharmaceutical crop. Thus, studying the molecular mechanism of tuberous root development and storage is very important. However, not too much progress has been made in this field. In this study, we employed the next generation high-throughput deep sequencing technology to sequence all small RNAs and degradome of sweetpotato for systematically investigating sweetpotato response to chilling stress during storage. A total of 190 known microRNAs (miRNAs) and 191 novel miRNAs were identified, and 428 transcripts were targeted by 184 identified miRNAs. More importantly, we identified 26 miRNAs differentially expressed between chilling stress and control conditions. The expression of these miRNAs and their targets was also confirmed by qRT-PCR. Integrated analysis of small RNAs and degradome sequencing reveals that miRNA-mediated SA signaling, ABA-dependent, and ROS response pathways are involved in sweetpotato root response to chilling stress during storage. PMID- 29185496 TI - The effect of primary total knee arthroplasty on the incidence of falls and balance-related functions in patients with osteoarthritis. AB - Knee osteoarthritis (OA) is an established risk factor for falls and balance impairment. This study investigated the incidence of falls, balance-related outcomes and risk factors for falls before and after primary total knee arthroplasty (TKA). Three hundred seventy-six OA patients scheduled to undergo TKA were included. Falls data within the preoperative, first postoperative and second postoperative years were collected, balance-related functions were assessed using the Assessment of Quality of Life (AQoL), WOMAC, Falls Efficacy Scale International (FES-I), Activities-specific Balance Confidence (ABC), knee extension strength, Berg Balance Scale (BBS) and Timed Up and Go (TUG) before surgery and 1 and 2 years after surgery. Compared with preoperative values, the incidence of falls significantly decreased (14.89%, 6.23% and 3.14% within the preoperative, first postoperative and second postoperative years, respectively) and the AQoL, WOMAC, FES-I, ABC, knee extension strength, BBS and TUG significantly improved after TKA. Logistic regression analysis revealed that Kellgren-Lawrence grade >= 3 of the contralateral knee was an independent risk factor for falls before and after TKA. Conclusively, primary TKA is associated with a reduced incidence of falls and improved balance-related functions, and the contralateral knee should be considered in the design of fall-prevention strategies in patients with OA. PMID- 29185498 TI - Activating electrochemical catalytic activity of bio-palladium by hybridizing with carbon nanotube as "e- Bridge". AB - Nano metal catalysts produced by bacteria has received increasing attention owing to its environmental friendly synthesis route. However, the formed metal nanoparticles are associated with poorly conductive cells and challenged to be electrochemically applied. In this study, Palladium (Pd) nanoparticles were synthesized by Shewanella oneidensis MR-1. We demonstrated the limitation of palladized cells (Pd-cells) serving as electro-catalysts can be relieved by hybridizing with the conductive carbon nanotubes (Pd-cells-CNTs hybrid). Compared to the Pd-cells, the electrochemical active surface area of Pd in Pd-cells-CNTs10 (the ratio of Pd/CNTs is 1/10 w/w) were dramatically increased by 68 times to 20.44 m2.g-1. A considerable enhancement of electrocatalytic activity was further confirmed for Pd-cells-CNTs10 as indicated by a 5-fold increase of steady state current density for nitrobenzene reduction at -0.55 V vs Ag/AgCl. These results indicate that the biogenetic palladium could has been an efficient electro catalyst but just limited due to lacking an electron transport path (e - Bridge). This finding may also be helpful to guide the way to electrochemically use other biogenetic metal nano-materials. PMID- 29185499 TI - The spectral, spatial and contrast sensitivity of human polarization pattern perception. AB - It is generally believed that humans perceive linear polarized light following its conversion into a luminance signal by diattenuating macular structures. Measures of polarization sensitivity may therefore allow a targeted assessment of macular function. Our aim here was to quantify psychophysical characteristics of human polarization perception using grating and optotype stimuli defined solely by their state of linear polarization. We show: (i) sensitivity to polarization patterns follows the spectral sensitivity of macular pigment; (ii) the change in sensitivity across the central field follows macular pigment density; (iii) polarization patterns are identifiable across a range of contrasts and scales, and can be resolved with an acuity of 15.4 cycles/degree (0.29 logMAR); and (iv) the human eye can discriminate between areas of linear polarization differing in electric field vector orientation by as little as 4.4 degrees . These findings, which support the macular diattenuator model of polarization sensitivity, are unique for vertebrates and approach those of some invertebrates with a well developed polarization sense. We conclude that this sensory modality extends beyond Haidinger's brushes to the recognition of quantifiable spatial polarization-modulated patterns. Furthermore, the macular origin and sensitivity of human polarization pattern perception makes it potentially suitable for the detection and quantification of macular dysfunction. PMID- 29185500 TI - A novel method for calculating the dynamic capillary force and correcting the pressure error in micro-tube experiment. AB - Micro-tube experiment has been implemented to understand the mechanisms of governing microcosmic fluid percolation and is extensively used in both fields of micro electromechanical engineering and petroleum engineering. The measured pressure difference across the microtube is not equal to the actual pressure difference across the microtube. Taking into account the additional pressure losses between the outlet of the micro tube and the outlet of the entire setup, we propose a new method for predicting the dynamic capillary pressure using the Level-set method. We first demonstrate it is a reliable method for describing microscopic flow by comparing the micro-model flow-test results against the predicted results using the Level-set method. In the proposed approach, Level-set method is applied to predict the pressure distribution along the microtube when the fluids flow along the microtube at a given flow rate; the microtube used in the calculation has the same size as the one used in the experiment. From the simulation results, the pressure difference across a curved interface (i.e., dynamic capillary pressure) can be directly obtained. We also show that dynamic capillary force should be properly evaluated in the micro-tube experiment in order to obtain the actual pressure difference across the microtube. PMID- 29185501 TI - Random Combinatorial Gradient Metasurface for Broadband, Wide-Angle and Polarization-Independent Diffusion Scattering. AB - This paper proposes an easy, efficient strategy for designing broadband, wide angle and polarization-independent diffusion metasurface for radar cross section (RCS) reduction. A dual-resonance unit cell, composed of a cross wire and cross loop (CWCL), is employed to enhance the phase bandwidth covering the 2pi range. Both oblique-gradient and horizontal-gradient phase supercells are designed for illustration. The numerical results agree well with the theoretical ones. To significantly reduce backward scattering, the random combinatorial gradient metasurface (RCGM) is subsequently constructed by collecting eight supercells with randomly distributed gradient directions. The proposed metasurface features an enhanced specular RCS reduction performance and less design complexity compared to other candidates. Both simulated and measured results show that the proposed RCGM can significantly suppress RCS and exhibits broadband, wide-angle and polarization independence features. PMID- 29185502 TI - Selective uptake and sensing of nitrate in poly(3,4-ethylenedioxythiophene). AB - Nitrogen (N) as a nutrient, in the form of nitrate (NO3-), is essential for plant growth. Chemical fertilizers are used to increase crop yields, but overuse can lead to forms of environmental pollution necessitating methods to detect and monitor the level of NO3- in-situ in agricultural soils. Herein we report for the first time the NO3- selectivity of the inherently conducting polymer poly (3,4 ethylenedioxythiophene) (PEDOT). This selectivity occurs when PEDOT thin films are exposed to an aqueous environment containing not only NO3-, but a mixture of other ions present in concentrations (ppm) typical of real agricultural soil. The PEDOT sensitivity to absorb NO3- from solution is determined to be <1 ppm. PMID- 29185503 TI - Publisher correction: Young inversion with multiple linked QTLs under selection in a hybrid zone.

This has now been corrected in all versions of the Article. PMID- 29185504 TI - Adaptive evolution by spontaneous domain fusion and protein relocalization. AB - Knowledge of adaptive processes encompasses understanding the emergence of new genes. Computational analyses of genomes suggest that new genes can arise by domain swapping; however, empirical evidence has been lacking. Here we describe a set of nine independent deletion mutations that arose during selection experiments with the bacterium Pseudomonas fluorescens in which the membrane spanning domain of a fatty acid desaturase became translationally fused to a cytosolic di-guanylate cyclase, generating an adaptive 'wrinkly spreader' phenotype. Detailed genetic analysis of one gene fusion shows that the mutant phenotype is caused by relocalization of the di-guanylate cyclase domain to the cell membrane. The relative ease by which this new gene arose, along with its functional and regulatory effects, provides a glimpse of mutational events and their consequences that are likely to have a role in the evolution of new genes. PMID- 29185505 TI - Worldwide patterns of human epigenetic variation. AB - DNA methylation is an epigenetic modification, influenced by both genetic and environmental variation, that plays a key role in transcriptional regulation and many organismal phenotypes. Although patterns of DNA methylation have been shown to differ between human populations, it remains to be determined how epigenetic diversity relates to the patterns of genetic and gene expression variation at a global scale. Here we measured DNA methylation at 485,000 CpG sites in five diverse human populations, and analysed these data together with genome-wide genotype and gene expression data. We found that population-specific DNA methylation mirrors genetic variation, and has greater local genetic control than mRNA levels. We estimated the rate of epigenetic divergence between populations, which indicates far greater evolutionary stability of DNA methylation in humans than has been observed in plants. This study provides a deeper understanding of worldwide patterns of human epigenetic diversity, as well as initial estimates of the rate of epigenetic divergence in recent human evolution. PMID- 29185506 TI - Host-specific infestation in early Cambrian worms. AB - Symbiotic relationships are widespread in terrestrial and aquatic animals today, but evidence of symbiosis in the fossil record between soft-bodied bilaterians where the symbiont is intimately associated with the integument of the host is extremely rare. The radiation of metazoan life apparent in the Ediacaran (~635 541 million years ago) and Cambrian (~541-488 million years ago) periods is increasingly accepted to represent ecological diversification resulting from earlier key genetic developmental events and other innovations that occurred in the late Tonian and Cryogenian periods (~850-635 million years ago). The Cambrian has representative animals in each major ecospace category, the early Cambrian in particular having witnessed the earliest known complex animal communities and trophic structures, including symbiotic relationships. Here we report on newly discovered Cricocosmia and Mafangscolex worms that are hosts to aggregates of a new species of tiny worm in the lower Cambrian (Series 2, Stage 3) Chengjiang Lagerstatte of Yunnan Province, southwest China. The worm associations suggest the earliest known record of aggregate infestation of the integument of a soft bodied bilaterian, host specificity and host shift. PMID- 29185507 TI - Chromosomal inversion differences correlate with range overlap in passerine birds. AB - Chromosomal inversions evolve frequently but the reasons for this remain unclear. We used cytological descriptions of 411 species of passerine birds to identify large pericentric inversion differences between species, based on the position of the centromere. Within 81 small clades comprising 284 of the species, we found 319 differences on the 9 largest autosomes combined, 56 on the Z chromosome, and 55 on the W chromosome. We also identified inversions present within 32 species. Using a new fossil-calibrated phylogeny, we examined the phylogenetic, demographic and genomic context in which these inversions have evolved. The number of inversion differences between closely related species is consistently predicted by whether the ranges of species overlap, even when time is controlled for as far as is possible. Fixation rates vary across the autosomes, but inversions are more likely to be fixed on the Z chromosome than the average autosome. Variable mutagenic input alone (estimated by chromosome size, map length, GC content or repeat density) cannot explain the differences between chromosomes in the number of inversions fixed. Together, these results support a model in which inversions increase because of their effects on recombination suppression in the face of hybridization. Other factors associated with hybridization may also contribute, including the possibility that inversions contain incompatibility alleles, making taxa less likely to collapse following secondary contact. PMID- 29185508 TI - Direct and cascading impacts of tropical land-use change on multi-trophic biodiversity. AB - The conversion of tropical rainforest to agricultural systems such as oil palm alters biodiversity across a large range of interacting taxa and trophic levels. Yet, it remains unclear how direct and cascading effects of land-use change simultaneously drive ecological shifts. Combining data from a multi-taxon research initiative in Sumatra, Indonesia, we show that direct and cascading land use effects alter biomass and species richness of taxa across trophic levels ranging from microorganisms to birds. Tropical land use resulted in increases in biomass and species richness via bottom-up cascading effects, but reductions via direct effects. When considering direct and cascading effects together, land use was found to reduce biomass and species richness, with increasing magnitude at higher trophic levels. Our analyses disentangle the multifaceted effects of land use change on tropical ecosystems, revealing that biotic interactions on broad taxonomic scales influence the ecological outcome of anthropogenic perturbations to natural ecosystems. PMID- 29185509 TI - Genomic insights into the ancient spread of Lyme disease across North America. AB - Lyme disease is the most prevalent vector-borne disease in North America and continues to spread. The disease was first clinically described in the 1970s in Lyme, Connecticut, but the origins and history of spread of the Lyme disease bacteria, Borrelia burgdorferi sensu stricto (s.s.), are unknown. To explore the evolutionary history of B. burgdorferi in North America, we collected ticks from across the USA and southern Canada from 1984 to 2013 and sequenced the, to our knowledge, largest collection of 146 B. burgdorferi s.s. genomes. Here, we show that B. burgdorferi s.s. has a complex evolutionary history with previously undocumented levels of migration. Diversity is ancient and geographically widespread, well pre-dating the Lyme disease epidemic of the past ~40 years, as well as the Last Glacial Maximum ~20,000 years ago. This means the recent emergence of human Lyme disease probably reflects ecological change-climate change and land use changes over the past century-rather than evolutionary change of the bacterium.

AB - Seasonal cycles of primary production (phenology) critically influence biogeochemical cycles, ecosystem structure and climate. In the oceans, primary production is dominated by microbial phytoplankton that drift with currents, and show rapid turnover and chaotic dynamics, factors that have hindered understanding of their phenology. We used all available observations of upper ocean phytoplankton concentration (1995-2015) to describe global patterns of phytoplankton phenology, the environmental factors that structure them, and their relationships to terrestrial patterns. Phytoplankton phenologies varied strongly by latitude and productivity regime: those in high-production regimes were governed by insolation, whereas those in low-production regimes were constrained by vertical mixing. In eight of ten ocean regions, our findings contradict the hypothesis that phytoplankton phenologies are coherent at basin scales. Lastly, the spatial organization of phenological patterns in the oceans was broadly similar to those on land, suggesting an overarching effect of insolation on the phenology of primary producers globally. PMID- 29185512 TI - Female cuckoo calls misdirect host defences towards the wrong enemy. AB - Prey are sensitive to even subtle cues of predation risk, which provides the evolutionary potential for parasites to exploit host risk perception. Brood parasitic common cuckoos (Cuculus canorus) lay their eggs in the nests of host species and their secretive laying behaviour enables them to evade host defences. Therefore, it seems paradoxical that female cuckoos often give a conspicuous 'chuckle' call after parasitizing a host's clutch. Here, we show that this hawk like chuckle call increases the success of parasitism by diverting host parents' attention away from the clutch and towards their own safety. In our field experiments, reed warbler (Acrocephalus scirpaceus) hosts paid no more attention to the 'cuck-oo' call of the male common cuckoo than the call of a harmless dove. However, the chuckle call of the female cuckoo had the same effect as the call of a predatory hawk in distracting the warblers' attention and reducing rejection of a foreign egg. Our results show that the female cuckoo enhances her success by manipulating a fundamental trade-off in host defences between clutch and self protection. PMID- 29185513 TI - Crafty cuckoo calls. PMID- 29185514 TI - Community-wide integration of floral colour and scent in a Mediterranean scrubland. AB - Angiosperm flowers have evolved a dazzling palette of colours and a rich bouquet of scents, principally serving to attract pollinators. Despite recent progress in the ecology of pollination, the sensory floral traits that are important for communication with pollinators (for example, colour and scent) have not been assessed in an unbiased, integrative sense within a community context. Nonetheless, floral sensory stimuli are known key factors that mediate flower visitation, thus affecting community dynamics. Here we show that flowers of the phrygana, a natural Mediterranean scrubland, display integrated patterns of scent composition and colour (as perceived by pollinators). Surprisingly, the data reveal predictive relationships between patterns of volatile composition and flower reflectance spectra. The presence of nectar is related to visual cues and the qualitative composition of floral aromas. Our results reveal a coordinated phenotypic integration consistent with the sensory abilities and perceptual biases of bees, suggesting potential facilitative effects for pollination and highlighting the fundamental importance of bees in Mediterranean-type ecosystems. We offer our unbiased approach as a starting point for more extensive, global investigations of the diversity of floral sensory phenotypes and its role in the community ecology of plant-pollinator interactions. PMID- 29185515 TI - Intermediate degrees of synergistic pleiotropy drive adaptive evolution in ecological time. AB - Rapid phenotypic evolution of quantitative traits can occur within years, but its underlying genetic architecture remains uncharacterized. Here we test the theoretical prediction that genes with intermediate pleiotropy drive adaptive evolution in nature. Through a resurrection experiment, we grew Arabidopsis thaliana accessions collected across an 8-year period in six micro-habitats representative of that local population. We then used genome-wide association mapping to identify the single-nucleotide polymorphisms (SNPs) associated with evolved and unevolved traits in each micro-habitat. Finally, we performed a selection scan by testing for temporal differentiation in these SNPs. Phenotypic evolution was consistent across micro-habitats, but its associated genetic bases were largely distinct. Adaptive evolutionary change was most strongly driven by a small number of quantitative trait loci (QTLs) with intermediate degrees of pleiotropy; this pleiotropy was synergistic with the per-trait effect size of the SNPs, increasing with the degree of pleiotropy. In addition, weak selection was detected for frequent micro-habitat-specific QTLs that shape single traits. In this population, A. thaliana probably responded to local warming and increased competition, in part mediated by central regulators of flowering time. This genetic architecture, which includes both synergistic pleiotropic QTLs and distinct QTLs within particular micro-habitats, enables rapid phenotypic evolution while still maintaining genetic variation in wild populations. PMID- 29185516 TI - A Devonian tetrapod-like fish reveals substantial parallelism in stem tetrapod evolution. AB - The fossils assigned to the tetrapod stem group document the evolution of terrestrial vertebrates from lobe-finned fishes. During the past 18 years the phylogenetic structure of this stem group has remained remarkably stable, even when accommodating new discoveries such as the earliest known stem tetrapod Tungsenia and the elpistostegid (fish-tetrapod intermediate) Tiktaalik. Here we present a large lobe-finned fish from the Late Devonian period of China that disrupts this stability. It combines characteristics of rhizodont fishes (supposedly a basal branch in the stem group, distant from tetrapods) with derived elpistostegid-like and tetrapod-like characters. This melange of characters may reflect either detailed convergence between rhizodonts and elpistostegids plus tetrapods, under a phylogenetic scenario deduced from Bayesian inference analysis, or a previously unrecognized close relationship between these groups, as supported by maximum parsimony analysis. In either case, the overall result reveals a substantial increase in homoplasy in the tetrapod stem group. It also suggests that ecological diversity and biogeographical provinciality in the tetrapod stem group have been underestimated. PMID- 29185517 TI - Author Correction: ISS observations offer insights into plant function. AB - In the version of this Comment previously published, in Box 1, the spacing of the GEDI footprints should have read 60 m along the track, not 25 m. Also the second affiliation for Susan Ustin was incorrect, she is only associated with the University of California, Davis. These errors have now been corrected. PMID- 29185518 TI - Deep faunistic turnovers preceded the rise of dinosaurs in southwestern Pangaea. AB - The Triassic period documents the origin and diversification of modern amniote lineages and the Late Triassic fossil record of South America has been crucial to shed light on these early evolutionary histories. However, the faunistic changes that led to the establishment of Late Triassic ecosystems are largely ignored because of the global scarcity of fossils from assemblages a few million years older. Here we contribute to fill this gap with the description of a new tetrapod assemblage from the lowermost levels of the Chanares Formation (uppermost Middle lower Late Triassic epochs) of Argentina, which is older than the other vertebrate assemblages of the same basin. The new assemblage is composed of therapsids, rhynchosaurids and archosaurs, and clearly differs from that of the immediately overlying and well-known historical Chanares vertebrate assemblage. The new tetrapod association is part of a phase of relatively rapidly changing vertebrate assemblage compositions, in a time span shorter than 6 million years, before the diversification of dinosaurs and other common Late Triassic tetrapods in southwestern Pangaea. PMID- 29185519 TI - The skull roof tracks the brain during the evolution and development of reptiles including birds. AB - Major transformations in brain size and proportions, such as the enlargement of the brain during the evolution of birds, are accompanied by profound modifications to the skull roof. However, the hypothesis of concerted evolution of shape between brain and skull roof over major phylogenetic transitions, and in particular of an ontogenetic relationship between specific regions of the brain and the skull roof, has never been formally tested. We performed 3D morphometric analyses to examine the deep history of brain and skull-roof morphology in Reptilia, focusing on changes during the well-documented transition from early reptiles through archosauromorphs, including nonavian dinosaurs, to birds. Non avialan taxa cluster tightly together in morphospace, whereas Archaeopteryx and crown birds occupy a separate region. There is a one-to-one correspondence between the forebrain and frontal bone and the midbrain and parietal bone. Furthermore, the position of the forebrain-midbrain boundary correlates significantly with the position of the frontoparietal suture across the phylogenetic breadth of Reptilia and during the ontogeny of individual taxa. Conservation of position and identity in the skull roof is apparent, and there is no support for previous hypotheses that the avian parietal is a transformed postparietal. The correlation and apparent developmental link between regions of the brain and bony skull elements are likely to be ancestral to Tetrapoda and may be fundamental to all of Osteichthyes, coeval with the origin of the dermatocranium. PMID- 29185520 TI - Gut-like ectodermal tissue in a sea anemone challenges germ layer homology. AB - Cnidarians (for example, sea anemones and jellyfish) develop from an outer ectodermal and inner endodermal germ layer, whereas bilaterians (for example, vertebrates and flies) additionally have a mesodermal layer as intermediate germ layer. Currently, cnidarian endoderm (that is, 'mesendoderm') is considered homologous to both bilaterian endoderm and mesoderm. Here we test this hypothesis by studying the fate of germ layers, the localization of gut cell types, and the expression of numerous 'endodermal' and 'mesodermal' transcription factor orthologues in the anthozoan sea anemone Nematostella vectensis. Surprisingly, we find that the developing pharyngeal ectoderm and its derivatives display a transcription-factor expression profile (foxA, hhex, islet, soxB1, hlxB9, tbx2/3, nkx6 and nkx2.2) and cell-type combination (exocrine and insulinergic) reminiscent of the developing bilaterian midgut, and, in particular, vertebrate pancreatic tissue. Endodermal derivatives, instead, display cell functions and transcription-factor profiles similar to bilaterian mesoderm derivatives (for example, somatic gonad and heart). Thus, our data supports an alternative model of germ layer homologies, where cnidarian pharyngeal ectoderm corresponds to bilaterian endoderm, and the cnidarian endoderm is homologous to bilaterian mesoderm. PMID- 29185521 TI - Ichnological evidence for meiofaunal bilaterians from the terminal Ediacaran and earliest Cambrian of Brazil. AB - The evolutionary events during the Ediacaran-Cambrian transition (~541 Myr ago) are unparalleled in Earth history. The fossil record suggests that most extant animal phyla appeared in a geologically brief interval, with the oldest unequivocal bilaterian body fossils found in the Early Cambrian. Molecular clocks and biomarkers provide independent estimates for the timing of animal origins, and both suggest a cryptic Neoproterozoic history for Metazoa that extends considerably beyond the Cambrian fossil record. We report an assemblage of ichnofossils from Ediacaran-Cambrian siltstones in Brazil, alongside U-Pb radioisotopic dates that constrain the age of the oldest specimens to 555-542 Myr. X-ray microtomography reveals three-dimensionally preserved traces ranging from 50 to 600 MUm in diameter, indicative of small-bodied, meiofaunal tracemakers. Burrow morphologies suggest they were created by a nematoid-like organism that used undulating locomotion to move through the sediment. This assemblage demonstrates animal-sediment interactions in the latest Ediacaran period, and provides the oldest known fossil evidence for meiofaunal bilaterians. Our discovery highlights meiofaunal ichnofossils as a hitherto unexplored window for tracking animal evolution in deep time, and reveals that both meiofaunal and macrofaunal bilaterians began to explore infaunal niches during the late Ediacaran.

AB - Since its inception, archaeology has traditionally focused exclusively on humans and our direct ancestors. However, recent years have seen archaeological techniques applied to material evidence left behind by non-human animals. Here, we review advances made by the most prominent field investigating past non-human tool use: primate archaeology. This field combines survey of wild primate activity areas with ethological observations, excavations and analyses that allow the reconstruction of past primate behaviour. Because the order Primates includes humans, new insights into the behavioural evolution of apes and monkeys also can be used to better interrogate the record of early tool use in our own, hominin, lineage. This work has recently doubled the set of primate lineages with an excavated archaeological record, adding Old World macaques and New World capuchin monkeys to chimpanzees and humans, and it has shown that tool selection and transport, and discrete site formation, are universal among wild stone-tool-using primates. It has also revealed that wild capuchins regularly break stone tools in a way that can make them difficult to distinguish from simple early hominin tools. Ultimately, this research opens up opportunities for the development of a broader animal archaeology, marking the end of archaeology's anthropocentric era. PMID- 29185528 TI - The coexistence problem revisited. PMID- 29185529 TI - Shifting from a fertilization-dominated to a warming-dominated period. AB - Carbon dioxide and nitrogen fertilization effects on ecosystem carbon sequestration may slow down in the future because of emerging nutrient constraints, climate change reducing the effect of fertilization, and expanding land use change and land management and disturbances. Further, record high temperatures and droughts are leading to negative impacts on carbon sinks. We suggest that, together, these two phenomena might drive a shift from a period dominated by the positive effects of fertilization to a period characterized by the saturation of the positive effects of fertilization on carbon sinks and the rise of negative impacts of climate change. We discuss the evidence and processes that are likely to be leading to this shift. PMID- 29185530 TI - How do you treat epilepsy in pregnancy?

This article provides a framework for neurologists to implement a note release policy in their practice. PMID- 29185533 TI - Depression in epilepsy, migraine, and multiple sclerosis: Epidemiology and how to screen for it. AB - Purpose of review: To provide an overview of the epidemiology of depression in chronic neurologic conditions that can affect individuals throughout the lifespan (epilepsy, migraine, multiple sclerosis [MS]) and examine depression screening tools for adults with these conditions. Recent findings: Depression is common in neurologic conditions and can be associated with lower quality of life, higher health resource utilization, and poor adherence to treatment. It affects around 20%-30% of those with epilepsy, migraine, and MS, and evidence for a bidirectional association exists for each of these conditions. Depression screening tools generally perform well in neurologic conditions, but are not without limitations. Summary: Depression is a major contributor to poor outcomes in epilepsy, migraine, and MS. Although psychiatric resources are scarce globally, this is no reason to ignore depression in neurologic conditions. Depression screening tools are available in neurology and should be considered in clinical practice. PMID- 29185534 TI - Mild brain injury and anticoagulants: Less is enough. AB - Background: Despite the higher theoretical risk of traumatic intracranial hemorrhage (ICH) in anticoagulated patients with mild head injury, the value of sequential head CT scans to identify bleeding remains controversial. This study evaluated the utility of 2 sequential CT scans at a 48-hour interval (CT1 and CT2) in patients with mild head trauma (Glasgow Coma Scale 13-15) taking oral anticoagulants. Methods: We retrospectively evaluated the clinical records of all patients on chronic anticoagulation treatment admitted to the emergency department for mild head injury. Results: A total of 344 patients were included, and 337 (97.9%) had a negative CT1. CT2 was performed on 284 of the 337 patients with a negative CT1 and was positive in 4 patients (1.4%), but none of the patients developed concomitant neurologic worsening or required neurosurgery. Conclusions: Systematic routine use of a second CT scan in mild head trauma in patients taking anticoagulants is expensive and clinically unnecessary. PMID- 29185536 TI - Swallow-induced syncope in 5 patients: Electrophysiologic evaluation during swallowing. AB - Background: We sought to characterize a cohort of participants with swallow induced syncope (SIS) with clinical and electrophysiologic evaluations. Methods: Using electrocardiographic monitoring and neurophysiologic methods of swallowing, we evaluated a cohort of 5 patients with SIS, 4 of whom had longitudinal follow up. Results: We determined electrophysiologically that the duration between the onset of swallow and a bradyarrhythmia or asystole is extremely short (2-3 seconds) in SIS. Most participants with SIS do not have a neurologic or esophageal disorder. SIS can occur with different food types, in sitting or standing position, and has varying frequency in different participants. Permanent pacemaker placement is a curative measure in SIS. Conclusions: Our findings suggest that SIS is elicited by reflex afferent pathways originating in the oropharynx, rather than an esophageal origin, as previously proposed. Our longitudinally followed cohort with detailed clinical and electrophysiologic characterization should aid the clinician in the diagnosis and treatment of this potentially life-threatening condition.

AB - Purpose of review: To summarize behavioral interventions for the treatment of primary tic disorders. Recent findings: Although tics were attributed to a disordered weak volition, the shift towards neurobiological models of tic disorders also transformed nonpharmacologic treatment practices. Current international guidelines recommend habit reversal training, comprehensive behavioral intervention, and exposure and response prevention as first-line therapies for tics. Appropriate patient selection, including age and presence of comorbidities, are salient clinical features that merit consideration. Evidence for further behavioral interventions is also presented. Summary: Currently recommended behavioral interventions view tics as habitual responses that may be further strengthened through negative reinforcement. Although availability and costs related to these interventions may limit their effect, Internet-based and telehealth approaches may facilitate wide accessibility. Novel nonpharmacologic treatments that take different approaches, such as autonomic modulation or attention-based interventions, may also hold therapeutic promise. PMID- 29185539 TI - Progressive ataxia and palatal tremor. PMID- 29185540 TI - Functional movement disorders: Five new things. AB - Purpose of review: Functional movement disorders (FMD) are commonly seen in neurologic practice, but are associated with poor outcomes. Recent years have seen a resurgence of interest in this area, with new developments in pathophysiologic understanding and therapeutic management. Recent findings: Individuals with FMD are a psychologically heterogeneous group, with many individuals having no detectable psychopathology on symptom screening measures, and possibly significant etiologically relevant life events only revealed through in-depth interviews. A randomized trial of specialist intensive physical rehabilitation compared to community-based neurophysiotherapy in FMD has demonstrated moderate to large effect sizes for both physical and social functioning outcomes. Experimental evidence suggests an impairment in the neural systems conferring a sense of agency over movement in individuals with FMD, and may explain why movements that appear voluntary are not experienced as such. Summary: The prognosis of individuals with FMD may be improved with greater access to appropriately organized care and treatment.

AB - Purpose of review: In April 2016, the Food and Drug Administration (FDA) approved a first-in-class atypical antipsychotic medication called pimavanserin for the treatment of Parkinson disease psychosis (PDP). We aim to inform readers about its indications, effectiveness, and safety profile. Recent findings: Pimavanserin acts as an inverse agonist at serotonin 5-HT2A receptors and has negligible effects on other receptors, thereby avoiding the D2 receptor antagonism that can potentially worsen motor symptoms. Its FDA approval was based primarily on the results of a single randomized, placebo-controlled phase 3 trial. Summary: While pimavanserin appears to be a safe, effective, and well-tolerated therapeutic option for PDP, additional clinical trials and open-label extension studies are needed to determine the long-term safety and efficacy of this promising therapy. In the meantime, prescribers need to be aware of the possible adverse effects of pimavanserin including QT interval prolongation and a potential to cause a paradoxical worsening of symptoms.

PMID- 29185546 TI - Timed up and go test at tap test and shunt surgery in idiopathic normal pressure hydrocephalus. AB - Background: The 3-meter Timed Up and Go test (TUG) is a reliable quantitative test for assessment of gait and balance. We aimed to establish an optimal threshold of TUG at the tap test for predicting outcomes 12 months after shunt surgery in patients with idiopathic normal pressure hydrocephalus (iNPH). Methods: The TUG was measured in a total of 151 patients with possible iNPH before and after a tap test and 12 months after shunt surgery. Among them, 81 patients underwent ventriculoperitoneal shunt implantation (SINPHONI) and 70 underwent lumboperitoneal shunt implantation (SINPHONI-2). The areas under the curve (AUCs), sensitivities, and specificities for predicting shunt effectiveness were assessed. Results: The simple differences of time on TUG at the tap test were significantly more accurate for predicting shunt effectiveness than percent improvement of time. The highest AUC for the synchronized moving cutoff point of TUG time was 0.81 (sensitivity 81.0%; specificity 81.6%) at the threshold of 5 seconds in the SINPHONI-2. For predicting improvements of >=10 seconds 12 months after lumboperitoneal shunt implantation, the AUC was 0.90, and the sensitivity and specificity at the threshold of 5.6 seconds were 83.3% and 81.0%. Only for patients with a <5-second improvement at the tap test, ventriculoperitoneal shunt implantation conveyed significantly better improvements in TUG time 12 months after surgery than lumboperitoneal shunt implantation. Conclusions: An improvement of 5 seconds was a useful threshold of TUG time at the tap test for predicting a >=10-second improvement 12 months after shunt surgery, rather than the percent improvement of TUG time. PMID- 29185545 TI - Movement disorders and chronic psychosis: Five new things. AB - Purpose of review: To discuss selected peer-reviewed research articles published between 2014 and 2016 and highlight 5 clinically relevant messages related to hyperkinetic and hypokinetic movement disorders in patients with chronic psychosis. Recent findings: A recent population-based study complemented data from clinical trials in showing increased risk of developing extrapyramidal symptoms with antipsychotic use. A community service-based longitudinal study showed that dopamine transporter imaging could help identify subgroups of patients with parkinsonism associated with antipsychotics with a progressive course, potentially manageable with l-dopa. Data from recent noteworthy clinical trials showed that a new VMAT-2 inhibitor and, for pharmacologically refractory tardive dyskinesia, deep brain stimulation of the globus pallidus internus are promising interventions. Finally, a population-based study has confirmed that hyperkinesias (encompassing chorea, dystonia, and stereotypies) may be early predictors of psychosis even in childhood and adolescence. Summary: Movement disorders associated with new-generation antipsychotics, including widely used agents (e.g., aripiprazole), are not rare occurrences. Better monitoring is needed to assess their true effect on patients' quality of life and functioning and to prevent underascertainment.

AB - Purpose of review: Biosensors capable of measuring physiologic and kinetic parameters associated with disability are being applied to the study of people with multiple sclerosis (MS). We review the use of biosensors in people with MS with an emphasis on measuring/monitoring disability and understanding knowledge gaps between biosensor data and clinical care. Recent findings: Accelerometers are available to the public and may be able to help the clinician understand a patient's degree of disability. Further studies with wearable biosensors capable of measuring other physiologic features, such as vital signs, are needed and are likely to contribute to our understanding of MS. Summary: Wearable biosensors can improve our understanding of disability, response to treatment, and natural history of MS. PMID- 29185553 TI - Neurologists should endorse active transportation for their patients. AB - It has been well-established that social determinants prevent far more deaths than medical care. Both behavior and social circumstance are closely linked to transportation. The connection between health and transportation is both direct (pedestrian injury, for example) and indirect (commuting access to work leading to employer-based health insurance, for example). Thus, transportation policy and health policy are interrelated. Neurologists should join community partnerships to promote safe and healthy transportation options for all people but especially for their patients. PMID- 29185554 TI - Pure lemniscal sensory stroke. PMID- 29185555 TI - Perspectives on marijuana use and effectiveness: A survey of NARCOMS participants. AB - Background: Interest in and use of marijuana by persons with multiple sclerosis (MS) has increased. While potential benefits have been reported, so have concerns about potential risks. Few large studies have been conducted about the perceptions and current usage of marijuana and medical cannabinoids in persons with MS. Methods: Participants in the North American Research Committee on Multiple Sclerosis (NARCOMS) registry were surveyed in 2014 regarding legality and history of marijuana usage, both before and after diagnosis with MS. Results: A total of 5,481 participants responded, with 78.2% female, 90% relapsing disease at onset, and a current mean age of 55.5 (10.2) years. Sixty-four percent had tried marijuana prior to their MS diagnosis, 47% have considered using for their MS, 26% have used for their MS, 20% have spoken with their physician about use, and 16% are currently using marijuana. Ninety-one percent think marijuana should be legal in some form. Men, those with higher disability, current and past nicotine smokers, and younger age were associated with a higher likelihood of current use. Conclusions: The majority of responders favor legalization and report high interest in the use of marijuana for treatment of MS symptoms, but may be reluctant to discuss this with health care providers. Health care providers should systematically inquire about use of marijuana. PMID- 29185556 TI - Online tools for individuals with depression and neurologic conditions: A scoping review. AB - Background: Patients with neurologic conditions commonly have depression. Online tools have the potential to improve outcomes in these patients in an efficient and accessible manner. We aimed to identify evidence-informed online tools for patients with comorbid neurologic conditions and depression. Methods: A scoping review of online tools (free, publicly available, and not requiring a facilitator) for patients with depression and epilepsy, Parkinson disease (PD), multiple sclerosis (MS), traumatic brain injury (TBI), or migraine was conducted. MEDLINE, EMBASE, PsycINFO, Cochrane Database of Systematic Reviews, and Cochrane CENTRAL Register of Controlled Trials were searched from database inception to January 2017 for all 5 neurologic conditions. Gray literature using Google and Google Scholar as well as app stores for both Android and Apple devices were searched. Self-management or self-efficacy online tools were not included unless they were specifically targeted at depression and one of the neurologic conditions and met the other eligibility criteria. Results: Only 4 online tools were identified. Of these 4 tools, 2 were web-based self-management programs for patients with migraine or MS and depression. The other 2 were mobile apps for patients with PD or TBI and depression. No online tools were found for epilepsy. Conclusions: There are limited depression tools for people with neurologic conditions that are evidence-informed, publicly available, and free. Future research should focus on the development of high-quality, evidence-based online tools targeted at neurologic patients. PMID- 29185558 TI - Analytical solution of the PELDOR inverse problem using the integral Mellin transform. AB - We describe a new model-free approach to solve the inverse problem in pulsed double electron-electron resonance (PELDOR, also known as DEER) spectroscopy and obtain the distance distribution function between two radicals from time-domain PELDOR data. The approach is based on analytical solutions of the Fredholm integral equations of the first kind using integral Mellin transforms to provide the distance distribution function directly. The approach appears to confine the noise in the computed distance distribution to short distances and does not introduce systematic distortions. Thus, the proposed analysis method can be a useful supplement to current methods to determine complicated distance distributions. PMID- 29185557 TI - Frequency, determinants, and effects of early seizures after thrombolysis for acute ischemic stroke: The ENCHANTED trial. AB - Background: Seizures after ischemic stroke have not been well-studied. We aim to determine the frequency, determinants, and significance of early seizures after thrombolysis for acute ischemic stroke. Methods: Data are from the Enhanced Control of Hypertension and Thrombolysis Stroke Study (ENCHANTED), an international, multicenter, randomized controlled trial where patients with acute ischemic stroke were randomized to low-dose (0.6 mg/kg) or standard-dose (0.9 mg/kg) IV alteplase. The protocol prespecified prospective data collection on in hospital seizures over 7 days postrandomization. Logistic regression models were used to determine variables associated with seizures and their significance on poor outcomes of death or disability (modified Rankin scale scores 3-6), symptomatic intracerebral hemorrhage (sICH), and European Quality of Life 5 Dimensions questionnaire [EQ-5D] over 90 days. Results: Data were available for 3,139 acute ischemic stroke participants, of whom 42 (1.3%) had seizures at a median 22.7 hours after the onset of symptoms. Baseline variables associated with seizures were male sex (odds ratio [OR] 2.19, 95% confidence interval [CI] 1.07 4.50), severe neurologic impairment (NIH Stroke Scale score >=10; OR 2.16, 95% CI 1.06-4.40), and fever (OR 4.55, 95% CI 2.37-8.71). Seizures independently predicted poor recovery: death or major disability (OR 2.88, 95% CI 1.28-6.47), unfavorable ordinal shift of mRS scores (OR 1.94, 95% CI 1.10-3.39), and lower than median EQ-5D health utility index score (OR 3.50, 95% CI 1.37-8.91). There was no association of seizures with sICH in adjusted analysis. Conclusions: In thrombolysis-treated patients with acute ischemic stroke, seizures are uncommon, occur early, and predict poor recovery. Clinicaltrialsgov identifier: NCT01422616. PMID- 29185559 TI - Quantitative evaluation of analyte transport on microfluidic paper-based analytical devices (MUPADs). AB - The transport efficiency during capillary flow-driven sample transport on microfluidic paper-based analytical devices (MUPADs) made from filter paper has been investigated for a selection of model analytes (Ni2+, Zn2+, Cu2+, PO43-, bovine serum albumin, sulforhodamine B, amaranth) representing metal cations, complex anions, proteins and anionic molecules. For the first time, the transport of the analytical target compounds rather than the sample liquid, has been quantitatively evaluated by means of colorimetry and absorption spectrometry based methods. The experiments have revealed that small paperfluidic channel dimensions, additional user operation steps (e.g. control of sample volume, sample dilution, washing step) as well as the introduction of sample liquid wicking areas allow to increase analyte transport efficiency. It is also shown that the interaction of analytes with the negatively charged cellulosic paper substrate surface is strongly influenced by the physico-chemical properties of the model analyte and can in some cases (Cu2+) result in nearly complete analyte depletion during sample transport. The quantitative information gained through these experiments is expected to contribute to the development of more sensitive MUPADs.

AB - Herein, few-layered titanate nanosheets with a large lateral size and surface functionalization were synthesized via the exfoliation of precursor layered composites in an organic medium. The combination of layered compounds, intercalated guests, and dispersion media has the potential for the synthesis of nanosheets with controlled lateral sizes, thicknesses, and surface chemistry through exfoliation. PMID- 29185563 TI - Adsorption and diffusion of hydrogen and oxygen in FCC-Co: a first-principles study. AB - Hydrogen and oxygen play an important role in the hydrogen embrittlement and oxidation of novel Co-based alloys with gamma/gamma' microstructure. In this study, the adsorption of hydrogen and oxygen atoms on the FCC-Co(111) surface and their diffusion behavior from the surface into the sub-layers and bulk have been investigated by means of first-principles calculations. It is observed that hydrogen and oxygen atoms prefer to adsorb on the fcc and hcp (threefold hollow) sites, respectively. The hydrogen atom can penetrate into the first and second sub-layers energetically, while it is not feasible for the oxygen atom as diffusion from the surface into the first sub-layer is more difficult. It is found that the calculated diffusion coefficients of hydrogen are in good agreement with the available experimental data. Finally, we briefly discuss the changes in total magnetic moment along the Oct-Tet-Oct diffusion path and the associated electronic structures. The present work is helpful to provide comprehensive guidance for the development and applications of novel Co-based alloys.

AB - The receptor tyrosine kinase Mer (MERTK) is a promising drug target in cancer, where it can influence the metastasis-promoting signaling of both tumor cells and immune cells alike; however, no small molecule probes currently exist to selectively image Mer. In this work, we design and synthesize a selective near infrared fluorescent molecular probe of Mer (MERi-SiR). Confocal microscopy of metastases in mice reveals predominant probe accumulation in Mer-expressing tumor associated macrophages. PMID- 29185564 TI - Identifying the structure of 4-chlorophenyl isocyanide adsorbed on Au(111) and Pt(111) surfaces by first-principles simulations of Raman spectra. AB - Surface Raman spectroscopy has become one of the most powerful analytical tools for interfacial structures. However, theoretical modeling for the Raman spectra of molecular adsorbate on metallic surfaces is a long-standing challenge because accurate descriptions of the electronic structure for both the metallic substrates and adsorbates are required. Here we present a quasi-analytical method for high-precision surface Raman spectra at the first principle level. Using this method, we correlate both geometrical and electronic structures of a single 4 chlorophenyl isocyanide (CPI) molecule adsorbed on a Au(111) or Pt(111) surface with its Raman spectra. The "finger-print" frequency shift of the CN stretching mode reveals the in situ configuration of CPI is vertical adsorption on the top site of the Au(111) surface, but a bent configuration when it adsorbs on the hollow site of the Pt(111) surface. Electronic structure calculations reveal that a pi-back donation mechanism often causes a red shift to the Raman response of CN stretching mode. In contrast, sigma donation as well as a wall effect introduces a blue shift to the CN stretching mode. A clear relationship for the dependence of Raman spectra on the surface electronic and geometrical information is built up, which largely benefits the understanding of chemical and physical changes during the adsorption. Our results highlight that high-precision theoretical simulations are essential for identifying in situ geometrical and electronic surface structures. PMID- 29185566 TI - Fluctuation enhancement of ion diffusivity in liquids. AB - The diffusivity of ions in liquid solutions is known either to decrease with an increase in the ion size or to have a single maximum depending on the ion size. This article presents evidence for the appearance of multiple maxima and thus multiple ion sizes with enhanced diffusivity. This is caused by destabilization of the ion solvation shell and only happens at the ion radii that correspond to changes of the ion coordination number, which happen with an increase in the ion size. Solvation shell fluctuations are activated which leads to additional ion motion with rearrangement of the shell. A theoretical model of this effect is derived and is shown to be in good agreement with molecular dynamics and experimental data. This result rewrites a long standing picture of ion transport as a function of ion size and introduces a new possibility in the search for highly conductive systems.

PMID- 29185571 TI - Capsaicin inhibits the metastasis of human papillary thyroid carcinoma BCPAP cells through the modulation of the TRPV1 channel. AB - Capsaicin (CAP), a potent transient receptor potential vanilloid type 1 (TRPV1) agonist, is a major ingredient of red pepper. Recently, capsaicin has attracted increasing attention owing to its multiple biological activities. However, the anticancer effects of capsaicin against various types of cancers, especially on thyroid carcinoma, have not been completely elucidated. TRPV1, which can be activated by capsaicin, plays a key role in many biological and physiological processes. In the present study, the anticancer properties of capsaicin against papillary thyroid cancer BCPAP cells were investigated. Our results indicated that TRPV1 and TRPV6 were universally expressed in different types of thyroid cell lines. Capsaicin could inhibit multiple steps of metastasis without affecting the viability of BCPAP cells. The activation of TRPV1 by capsaicin (25 100 MUM) significantly suppressed the migration and invasion of BCPAP cells as well as their adhesion. The protein levels of Snail1 and Twist1, two critical EMT transcription factors (EMT-TFs), dramatically decreased in a dose-dependent manner after capsaicin treatment, accompanied by the up-regulation of downstream protein E-cadherin. Subsequently, the activation of TRPV1 by capsaicin also caused significant inhibition of the expression of MMP-2 and MMP-9. Moreover, the inhibitory effects of capsaicin on the metastasis of BCPAP cells were abrogated by the pre-treatment of a specific TRPV1 antagonist (capsazepin). Our results suggest that the activation of TRPV1 by capsaicin is associated with the metastatic inhibition of papillary thyroid cancer BCPAP cells, indicating that targeting of TRPV1 functions remains a feasible strategy for cancer treatment. PMID- 29185572 TI - Thermoelectric properties and thermal stability of layered chalcogenides, TlScQ2, Q = Se, Te. AB - A few thallium based layered chalcogenides of alpha-NaFeO2 structure-type are known for their excellent thermoelectric properties and interesting topological insulator nature. TlScQ2 belongs to this structural category. In the present work, we have studied the electronic structure, electrical and thermal transport properties and thermal stability of the title compounds within the temperature range 2-600 K. Density functional theory (DFT) predicts a metallic nature for TlScTe2 and a semiconducting nature for TlScSe2. DFT calculations also show significant lowering of energies of frontier bands upon inclusion of spin-orbit coupling contribution in the calculation. The electronic structure also shows the simultaneous occurrence of holes and electron pockets for the telluride. Experiments reveal that the telluride shows a semi-metallic behaviour whereas the selenide is a semiconductor. The thermoelectric properties for both the materials were also investigated. Both these materials possess very low thermal conductivity which is an attractive feature for thermoelectrics. However, they lack thermal stability and decompose upon warming above room temperature, as evidenced from high temperature powder X-ray diffraction and thermal analysis. PMID- 29185573 TI - A light-driven modulation of electric conductance through the adsorption of azobenzene onto silicon-doped- and pyridine-like N3-vacancy graphene. AB - The ability to modulate the conductance of an electronic device under light irradiation is crucial to the practical applications of nanoscale electronics. Density functional theory calculations predict that the conductance of the photo responsive graphene-based nanocomposites can be tuned through the noncovalent adsorption of an azobenzene (AB) derivative onto pristine, Si-doped, and pyridine like N3-vacancy graphene. AB@graphene systems were found to exhibit a visible light response within the low-frequency region, rendering the trans-to-cis isomerizations of these nanocomposites under the irradiation of solar light. The excellent solar light absorption performances of these hybrids can then be used to modulate the conductance of both N3-vacancy- and Si-doped-graphene AB hybrids effectively through the reversible change of the effective conjugate length of the AB molecule in the photoisomerization. In addition, the solar thermal energy up to 1.53 eV per AB molecule can be stored in the designed nanocomposites with the doped graphene. These findings provide clues for making multifunctional materials with potential applications as both optically controlled nanoelectronics and solar energy storage devices.

AB - A series of ferrocenyl and ruthenocenyl conjugates with colchicine bearing a 1,2,3-triazole moiety were synthesized and their anticancer properties were evaluated. We found that the most potent metallocenyl derivatives Rc4 and Rc5 are 6-7 times more cytotoxic toward HepG2 cells, while Fc4 and Fc5 are two times more cytotoxic toward HCT116 cells as colchicine. We also found that compounds Fc4, Fc5, Rc1 and Rc3-Rc5 are able to induce apoptosis, while compound Fc2 arrests mitosis. PMID- 29185575 TI - Osteoinductive superparamagnetic Fe nanocrystal/calcium phosphate heterostructured microspheres. AB - Functional magnetic and biocompatible particles are of great interest because of their potential use in various bioapplications such as hyperthermia for cancer treatment, magnetic resonance imaging (MRI) contrast agents and drug delivery. Herein, we introduce a facile method for synthesizing magnetic Fe nanocrystal/Fe substituted calcium phosphate (Fe/FeCaP) heterostructured microspheres using a two-step procedure: (1) one-pot hydrothermal synthesis to prepare uniform-sized FeCaP microspheres and (2) post-reduction annealing at 600 degrees C for Fe extraction from FeCaP. This approach results in the fabrication of Fe/FeCaP heterostructured microspheres that exhibit superparamagnetism with a saturation magnetization of 10.77 emu g-1. The Fe/FeCaP particles annealed at 600 degrees C show a much higher magnetic moment compared with the non-annealed FeCaP particles. Moreover, T2-weighted MRI phantom images reveal that the Fe/FeCaP heterostructured microspheres possess higher relaxivity than paramagnetic FeCaP, demonstrating their potential as superior and biocompatible MRI contrast agents. Moreover, the enhancement in osteoconductivity for Fe/FeCaP microspheres without any evidence of cytotoxicity was verified. Our results demonstrate the great potential of multi-functional Fe/FeCaP microspheres for use as biocompatible bone regeneration agents as well as MRI contrast agents. PMID- 29185576 TI - In situ/operando characterization techniques for rechargeable lithium-sulfur batteries: a review. AB - Rechargeable lithium-sulfur (Li-S) batteries have recently attracted global research interest due to their high theoretical specific capacity and energy density. To improve the performance and cycling stability of Li-S batteries, a clear understanding of the electrochemical reaction process and the degradation mechanisms of the sulfur redox chemistry are extremely important. In the past few decades, various advanced in situ/operando characterization tools have emerged, which have facilitated the understanding of the degradation mechanisms and the further development of high-performance Li-S batteries. In this review, we have summarized recent significant advances in in situ/operando characterization techniques for Li-S batteries. In particular, because of the existence of the soluble polysulfide species during the charge/discharge process, many creative ideas have been introduced into in situ/operando characterization of the electrochemical process in Li-S batteries. PMID- 29185577 TI - Comparative investigation of sensing behaviors between gap and lattice plasmon modes in a metallic nanoring array. AB - Plasmonic nanostructures have become the most promising candidates for biosensing applications because of their miniature sizes, ease of integration, and high throughput detection. Both propagating and localized surface plasmon modes in the nanostructures have been used for sensing and biomolecular detection. However, to maximize the biosensing potential of nanostructures, the choice of an optimized sensing detection strategy among two plasmon modes depends on the relationship between the biomolecule sizes and field decay length of plasmon modes. Here, we propose and investigate plasmonic coupling on a single-crystalline gold film, wherein there are two distinct optical modes, a gap mode (localized surface plasmon) originating from the parallel coupling of a nanoring and a surface lattice mode (propagating surface plasmon) originating from the anti-parallel coupling of a nanoring in an array. The sensing performances of the above two modes are thoroughly investigated and compared by considering two aspects, i.e., bulk and surface sensitivities. It is demonstrated that there is a reciprocal relationship between bulk and surface sensitivities for two modes, which also illustrates that the surface sensitivity is indispensable to fully describe the sensing performance of nanostructures. Furthermore, due to their different decay lengths, the gap and surface lattice modes on a single optical substrate can achieve simultaneous detection of target analytes with various sizes. Therefore, we can provide a high performance sensing platform based on a metallic nanoring array for a broad range of biomolecules with various sizes. PMID- 29185578 TI - A spin crossover (SCO) active graphene-iron(ii) complex hybrid material. AB - The advancement of molecular electronics and spintronics requires novel hybrid materials with synergistic magnetic and electrical properties. The non-covalent functionalization of highly conductive graphene with magnetically bistable spin crossover (SCO) complexes may yield such a multifunctional material. In this regard, a graphene-Fe(ii) SCO complex hybrid (Gr-SCO) has been prepared by non covalently anchoring a pyrene decorated SCO complex with solution phase pre exfoliated few-layer graphene sheets. SQUID magnetometry revealed the preservation of SCO in the Gr-SCO hybrid material exhibiting more gradual spin state switching characteristics than in the bulk molecular complex. This persistence of SCO of a molecular Fe(ii) complex upon anchoring on the graphene surface has consequences towards the realization of SCO based applications: in (i) reversible spin state dependent band gap tuning of graphene with an SCO complex analogous to chemical doping of graphene, and (ii) to probe the spin state dependence of electrical conductivity modulation by wiring the anchoring group (pyrene) tethered SCO complex between chemically robust few-layer graphene electrodes. PMID- 29185579 TI - Subnanometer structure and function from ion beams through complex fluidics to fluorescent particles. AB - The vertical dimensions of complex nanostructures determine the functions of diverse nanotechnologies. In this paper, we investigate the unknown limits of such structure-function relationships at subnanometer scales. We begin with a quantitative evaluation of measurement uncertainty from atomic force microscopy, which propagates through our investigation from ion beam fabrication to fluorescent particle characterization. We use a focused beam of gallium ions to subtractively pattern silicon surfaces, and silicon nitride and silicon dioxide films. Our study of material responses quantifies the atomic limits of forming complex topographies with subnanometer resolution of vertical features over a wide range of vertical and lateral dimensions. Our results demonstrate the underutilized capability of this standard system for rapid prototyping of subnanometer structures in hard materials. We directly apply this unprecedented dimensional control to fabricate nanofluidic devices for the analytical separation of colloidal nanoparticles by size exclusion. Optical microscopy of single nanoparticles within such reference materials establishes a subnanometer limit of the fluidic manipulation of particulate matter and enables critical dimension particle tracking with subnanometer accuracy. After calibrating for optical interference within our multifunctional devices, which also enables device metrology and integrated spectroscopy, we reveal an unexpected relationship between nanoparticle size and emission intensity for common fluorescent probes. Emission intensity increases supervolumetrically with nanoparticle diameter and then decreases as nanoparticles with different diameters photobleach to similar values of terminal intensity. We propose a simple model to empirically interpret these surprising results. Our investigation enables new control and study of structure-function relationships at subnanometer scales. PMID- 29185584 TI - Monomer diffusion into static and evolving polymer networks during frontal photopolymerisation. AB - Frontal photopolymerisation (FPP) is a directional solidification process that converts monomer-rich liquid into crosslinked polymer solid by light exposure and finds applications ranging from lithography to 3D printing. Inherent to this process is the creation of an evolving polymer network that is exposed to a monomer bath. A combined theoretical and experimental investigation is performed to determine the conditions under which monomer from this bath can diffuse into the propagating polymer network and cause it to swell. First, the growth and swelling processes are decoupled by immersing pre-made polymer networks into monomer baths held at various temperatures. The experimental measurements of the network thickness are found to be in good agreement with theoretical predictions obtained from a nonlinear poroelastic model. FPP propagation experiments are then carried out under conditions that lead to swelling. Unexpectedly, for a fixed exposure time, swelling is found to increase with incident light intensity. The experimental data is well described by a novel FPP model accounting for mass transport and the mechanical response of the polymer network, providing key insights into how monomer diffusion affects the conversion profile of the polymer solid and the stresses that are generated during its growth. The predictive capability of the model will enable the fabrication of gradient materials with tuned mechanical properties and controlled stress development. PMID- 29185588 TI - Fasting: a major limitation for resistance exercise training effects in rodents. AB - Protocols that mimic resistance exercise training (RET) in rodents present several limitations, one of them being the electrical stimulus, which is beyond the physiological context observed in humans. Recently, our group developed a conditioning system device that does not use electric shock to stimulate rats, but includes fasting periods before each RET session. The current study was designed to test whether cumulative fasting periods have some influence on skeletal muscle mass and function. Three sets of male Wistar rats were used in the current study. The first set of rats was submitted to a RET protocol without food restriction. However, rats were not able to perform exercise properly. The second and third sets were then randomly assigned into three experimental groups: 1) untrained control rats, 2) untrained rats submitted to fasting periods, and 3) rats submitted to RET including fasting periods before each RET session. While the second set of rats performed a short RET protocol (i.e., an adaptation protocol for 3 weeks), the third set of rats performed a longer RET protocol including overload (i.e., 8 weeks). After the short-term protocol, cumulative fasting periods promoted loss of weight (P<0.001). After the longer RET protocol, no difference was observed for body mass, extensor digitorum longus (EDL) morphology or skeletal muscle function (P>0.05 for all). Despite no effects on EDL mass, soleus muscle displayed significant atrophy in the fasting experimental groups (P<0.01). Altogether, these data indicate that fasting is a major limitation for RET in rats. PMID- 29185589 TI - Bevacizumab and gefitinib enhanced whole-brain radiation therapy for brain metastases due to non-small-cell lung cancer. AB - Non-small-cell lung cancer (NSCLC) patients who experience brain metastases are usually associated with poor prognostic outcomes. This retrospective study proposed to assess whether bevacizumab or gefitinib can be used to improve the effectiveness of whole brain radiotherapy (WBRT) in managing patients with brain metastases. A total of 218 NSCLC patients with multiple brain metastases were retrospectively included in this study and were randomly allocated to bevacizumab gefitinib-WBRT group (n=76), gefitinib-WBRT group (n=77) and WBRT group (n=75). Then, tumor responses were evaluated every 2 months based on Response Evaluation Criteria in Solid Tumors version 1.0. Karnofsky performance status and neurologic examination were documented every 6 months after the treatment. Compared to the standard WBRT, bevacizumab and gefitinib could significantly enhance response rate (RR) and disease control rate (DCR) of WBRT (P<0.001). At the same time, RR and DCR of patients who received bevacizumab-gefitinib-WBRT were higher than those who received gefitinib-WBRT. The overall survival (OS) rates and progression-free survival (PFS) rates also differed significantly among the bevacizumab-gefitinib-WBRT (48.6 and 29.8%), gefitinib-WBRT (36.7 and 29.6%) and WBRT (9.8 and 14.6%) groups (P<0.05). Although bevacizumab-gefitinib-WBRT was slightly more toxic than gefitinib-WBRT, the toxicity was tolerable. As suggested by prolonged PFS and OS status, bevacizumab substantially improved the overall efficacy of WBRT in the management of patients with NSCLC. PMID- 29185590 TI - Short-term effects of stored homologous red blood cell transfusion on cardiorespiratory function and inflammation: an experimental study in a hypovolemia model. AB - The pathophysiological mechanisms associated with the effects of red blood cell (RBC) transfusion on cardiopulmonary function and inflammation are unclear. We developed an experimental model of homologous 14-days stored RBC transfusion in hypovolemic swine to evaluate the short-term effects of transfusion on cardiopulmonary system and inflammation. Sixteen healthy male anesthetized swine (68+/-3.3 kg) were submitted to controlled hemorrhage (25% of blood volume). Two units of non-filtered RBC from each animal were stored under blood bank conditions for 14 days. After 30 min of hypovolemia, the control group (n=8) received an infusion of lactated Ringer's solution (three times the removed volume). The transfusion group (n=8) received two units of homologous 14-days stored RBC and lactated Ringer's solution in a volume that was three times the difference between blood removed and blood transfusion infused. Both groups were followed up for 6 h after resuscitation with collection of hemodynamic and respiratory data. Cytokines and RNA expression were measured in plasma and lung tissue. Stored RBC transfusion significantly increased mixed oxygen venous saturation and arterial oxygen content. Transfusion was not associated with alterations on pulmonary function. Pulmonary concentrations of cytokines were not different between groups. Gene expression for lung cytokines demonstrated a 2 fold increase in mRNA level for inducible nitric oxide synthase and a 0.5-fold decrease in mRNA content for IL-21 in the transfused group. Thus, stored homologous RBC transfusion in a hypovolemia model improved cardiovascular parameters but did not induce significant effects on microcirculation, pulmonary inflammation and respiratory function up to 6 h after transfusion. PMID- 29185591 TI - Safety and efficacy of regional citrate anticoagulation in continuous blood purification treatment of patients with multiple organ dysfunction syndrome. AB - The aim of this study was to discuss the safety and efficacy of regional citrate anticoagulation (RCA) on continuous blood purification (CBP) during the treatment of multiple organ dysfunction syndrome (MODS). Thirty-five patients with MODS were divided into two groups: the local citrate anticoagulation (RCA) group, and the heparin-free blood purification (hfBP) group. The MODS severity was assessed according to Marshall's MODS score criteria. Blood coagulation indicators, blood pressure, filter lifespan, filter replacement frequency, anticoagulation indicators, and main metabolic and electrolyte indicators were analyzed and compared between RCA and hfBP groups. RCA resulted in lower blood pressure than hfBP. The filter efficacy in RCA treatment was longer than in the hfBP group. The blood clearance of creatine, blood urea nitrogen and uric acid was better in the RCA group. RCA also led to higher pH than hfBP. Neither treatment resulted in severe bleeding events. In addition, MODS score was positively correlated with prothrombin time and activated partial thromboplastin time but negatively correlated with platelet concentration. RCA is a safer and more effective method in CBP treatment; however, it could also lead to low blood pressure and blood alkalosis. PMID- 29185592 TI - Decellularization of placentas: establishing a protocol. AB - Biological biomaterials for tissue engineering purposes can be produced through tissue and/or organ decellularization. The remaining extracellular matrix (ECM) must be acellular and preserve its proteins and physical features. Placentas are organs of great interest because they are discarded after birth and present large amounts of ECM. Protocols for decellularization are tissue-specific and have not been established for canine placentas yet. This study aimed at analyzing a favorable method for decellularization of maternal and fetal portions of canine placentas. Canine placentas were subjected to ten preliminary tests to analyze the efficacy of parameters such as the type of detergents, freezing temperatures and perfusion. Two protocols were chosen for further analyses using histology, scanning electron microscopy, immunofluorescence and DNA quantification. Sodium dodecyl sulfate (SDS) was the most effective detergent for cell removal. Freezing placentas before decellularization required longer periods of incubation in different detergents. Both perfusion and immersion methods were capable of removing cells. Placentas decellularized using Protocol I (1% SDS, 5 mM EDTA, 50 mM TRIS, and 0.5% antibiotic) preserved the ECM structure better, but Protocol I was less efficient to remove cells and DNA content from the ECM than Protocol II (1% SDS, 5 mM EDTA, 0.05% trypsin, and 0.5% antibiotic). PMID- 29185593 TI - Behavioral cross-sensitization between testosterone and fenproporex in adolescent and adult rats. AB - The abuse of psychoactive drugs is considered a global health problem. During the last years, a relevant number of studies have investigated the relationship between anabolic-androgenic steroids (AAS) and other psychoactive drugs. AAS, such as testosterone, can cause a dependence syndrome that shares many features with the classical dependence to psychoactive substances. Pre-clinical evidence shows that there are interactions between testosterone and psychoactive drugs, such as cocaine. However, few studies have been performed to investigate the effect of repeated testosterone treatment on behavioral effects of amphetamine derivatives, such as fenproporex. The purpose of the present study was to investigate the effects of repeated testosterone administration on fenproporex induced locomotor activity in adolescent and adult rats. Adolescent male Wistar rats were injected with testosterone (10 mg/kg sc for 10 days). After 3 days, animals received an acute injection of fenproporex (3.0 mg/kg ip) and the locomotor activity was recorded during 40 min. Thirty days later, the same animals received the same treatment with testosterone followed by a fenproporex challenge injection as described above. Our results demonstrated that repeated testosterone induced behavioral sensitization to fenproporex in adolescent but not in adult rats. These findings suggest that repeated AAS treatment might increase the dependence vulnerability to amphetamine and its derivatives in adolescent rats. PMID- 29185594 TI - Simple protocol for population (Sanger) sequencing for Zika virus genomic regions. AB - BACKGROUND: A number of Zika virus (ZIKV) sequences were obtained using Next generation sequencing (NGS), a methodology widely applied in genetic diversity studies and virome discovery. However Sanger method is still a robust, affordable, rapid and specific tool to obtain valuable sequences. OBJECTIVE: The aim of this study was to develop a simple and robust Sanger sequencing protocol targeting ZIKV relevant genetic regions, as envelope protein and nonstructural protein 5 (NS5). In addition, phylogenetic analysis of the ZIKV strains obtained using the present protocol and their comparison with previously published NGS sequences were also carried out. METHODS: Six Vero cells isolates from serum and one urine sample were available to develop the procedure. Primer sets were designed in order to conduct a nested RT-PCR and a Sanger sequencing protocols. Bayesian analysis was used to infer phylogenetic relationships. FINDINGS: Seven complete ZIKV envelope protein (1,571 kb) and six partial NS5 (0,798 Kb) were obtained using the protocol, with no amplification of NS5 gene from urine sample. Two NS5 sequences presented ambiguities at positions 495 and 196. Nucleotide analysis of a Sanger sequence and consensus sequence of previously NGS study revealed 100% identity. ZIKV strains described here clustered within the Asian lineage. MAIN CONCLUSIONS: The present study provided a simple and low-cost Sanger protocol to sequence relevant genes of the ZIKV genome. The identity of Sanger generated sequences with published consensus NGS support the use of Sanger method for ZIKV population studies. The regions evaluated were able to provide robust phylogenetic signals and may be used to conduct molecular epidemiological studies and monitor viral evolution. PMID- 29185595 TI - First evidence of Zika virus venereal transmission in Aedes aegypti mosquitoes. AB - BACKGROUND: Aedes aegypti is considered the main Zika virus (ZIKV) vector, and is thought to be responsible for the 2015-2016 outbreak in Brazil. Zika positive Ae. aegypti males collected in the field suggest that vertical and/or venereal transmission of ZIKV may occur. OBJECTIVES: In this study, we aimed to demonstrate that venereal transmission of ZIKV by Ae. aegypti can occur under laboratory conditions. METHODS: Ae. aegypti collected in the city of Manaus, confirmed as negative for Zika, Dengue and Chikungunya virus by reverse transcription real-time polymerase chain reaction (RT-qPCR) (AaM3V- strain), were reared under laboratory conditions and used for the experiments. The ZIKV used in this study was isolated from a patient presenting with symptoms; ZIKV was confirmed by RT-qPCR. Experiment 1: virgin male mosquitoes of AaM3V- strain were intrathoracically inoculated with a ZIKV suspension; four days after injection, they were transferred to a cage containing virgin females of AaM3V- strain and left to copulate for five days. Experiment 2: virgin female mosquitoes of AaM3V- strain were orally infected with a ZIKV suspension by blood feeding membrane assay; nine days after blood feeding, they were placed in cages with Ae. aegypti AaM3V- virgin males and left to copulate for four days. After copulation, all mosquitoes were individually evaluated for viral infection by RT-qPCR. FINDINGS: The mean infection rate in Experiment 1 and Experiment 2 was 45% and 35%, respectively. In both experiments, cycle threshold values ranged from 13 to 35, indicating the presence of viral genomes. MAIN CONCLUSION: Ae. aegypti males intrathoracically inoculated with a ZIKV suspension are infected and can transmit the virus to uninfected females by mating. Moreover, Ae. aegypti females orally infected with a ZIKV suspension can transmit the virus to uninfected males by copulation. This study shows that ZIKV infection of Ae. aegypti mosquitoes occurs not only during blood feeding, but also during copulation. PMID- 29185596 TI - Single shot of 17D vaccine may not confer life-long protection against yellow fever. AB - The yellow fever (YF) vaccine has been used since the 1930s to prevent YF, which is a severe infectious disease caused by the yellow fever virus (YFV), and mainly transmitted by Culicidae mosquitoes from the genera Aedes and Haemagogus . Until 2013, the World Health Organization (WHO) recommended the administration of a vaccine dose every ten years. A new recommendation of a single vaccine dose to confer life-long protection against YFV infection has since been established. Recent evidence published elsewhere suggests that at least a second dose is needed to fully protect against YF disease. Here, we discuss the feasibility of administering multiple doses, the necessity for a new and modern vaccine, and recommend that the WHO conveys a meeting to discuss YFV vaccination strategies for people living in or travelling to endemic areas.

AB - OBJECTIVE: Analyze the evidence available in Brazilian theses on the elements of the socio-critical paradigm in the construction of knowledge and practices of nursing care. METHOD: An integrative literature review was carried out in the Theses Database of the Coordination for the Improvement of Higher Education Personnel and the Brazilian Digital Library of Theses and Dissertations. RESULTS: Of a total of 320 theses, only 19 had elements of the socio-critical paradigm in their construction, among which the use of participatory investigations stand out (especially action-research), which present interaction between the researcher and the participants, the use of data collection techniques such as focus groups and culture circles, and theoretical frameworks for analyzing the phenomena in their complexity. CONCLUSION: The support of the sociocritical paradigm attributes to nursing the character of a practical science and service to the community, being committed to social transformation by empowering people. PMID- 29185599 TI - Alcohol use and health behavior among nursing professionals. AB - OBJECTIVE: To evaluate the problematic use of alcohol and health behavior among the nursing staff of a general hospital. METHOD: Cross-sectional study conducted at a general hospital. A questionnaire with socio-demographic information, the alcohol and substance use screening test, and a questionnaire on health behavior were applied. RESULTS: A total of 416 professionals participated in the study. In the final model of logistical regression, male professionals (OR 4.3), singles (OR 3.7), those that professed to having other religions (OR 3.8), worked as nursing technician (OR 2.3), did not consume low doses of alcoholic beverages per day (OR 2.0), used tobacco (OR 8.9), avoided consuming beverages with caffeine (OR 1.9) and avoided noisy environments (OR 2.0) showed higher chances of consuming alcohol at a problematic level. CONCLUSION: Among nursing professionals, the use of alcohol and not engaging in health behavior are strongly associated. These findings have implications for the implementation of strategies for the promotion of health and the prevention of alcohol use in work relationships. PMID- 29185600 TI - Indications of comprehensiveness in the pedagogical relationship: a design to be constructed in nursing education. AB - OBJECTIVE: To analyze how the indications of comprehensiveness translate into the teaching-learning process in a nursing undergraduate course. METHOD: Qualitative case study carried out with professors of a Nursing Undergraduate Course. Data collection occurred through documentary analysis, non-participant observation and individual interviews. Data analysis was guided from an analytical matrix following the steps of the operative proposal. RESULTS: Eight professors participated in the study. Some indications of comprehensiveness such as dialogue, listening, mutual respect, bonding and welcoming are present in the daily life of some professors. The indications of comprehensiveness are applied by some professors in the pedagogical relationship. The results refer to the Comprehensiveness of teaching-learning in a single and double loop model, and in this the professor and the student assume an open posture for new possibilities in the teaching-learning process. CONCLUSION: Comprehensiveness, as it is recognized as a pedagogical principle, allows the disruption of a professor centered teaching and advances in collective learning, enabling the professor and student to create their own design anchored in a reflective process about their practices and the reality found in the health services. PMID- 29185601 TI - Adherence to central venous catheter insertion bundle in neonatal and pediatric units. AB - OBJECTIVE: To describe the observed behavior of professionals in two neonatal and pediatric intensive care units regarding the use of central venous catheter insertion bundle, and the clinical and birth profile of neonates and children who received the devices. METHOD: A quantitative descriptive exploratory study was conducted in two intensive care units of a public hospital in Belo Horizonte with neonates and children, between February and September 2016. RESULTS: The sample consisted of 59 observed implants of central venous catheter. Most patients were male preterm infants, of cesarean delivery and proper weight according to the gestational age. Among all procedures observed, only three followed all recommendations for the central venous catheter insertion bundle. Incorrect techniques were observed while performing surgical antisepsis and inadequate use of chlorhexidine, an antiseptic. CONCLUSION: The findings highlight the importance of more investment in continuous training of the team on the prevention of bloodstream infection caused by central venous catheter to reduce the number of adverse events related to intravenous therapy. PMID- 29185602 TI - The first study of molecular prevalence and species characterization of Cryptosporidium in free-range chicken (Gallus gallus domesticus) from Brazil. AB - Rearing free-range chicken is based on grazing feeding patterns, and these animals could be potential environmental contaminants of Cryptosporidium oocysts for humans and other animals. Therefore, the present study aimed to evaluate the molecular prevalence of Cryptosporidium spp. in free-range chickens from Brazil. A total of 351 fecal samples from chickens were examined from 20 farms. For detection of Cryptosporidium spp., 18S rRNA gene fragments were amplified using a nested PCR reaction. Positive samples were sent for sequencing. The overall prevalence of Cryptosporidium was 25.6% (95% CI = 21.2% - 30.6%). Sequencing of the amplified fragments allowed for the identification of three species: C. meleagridis in 57 (62.6%), C. baileyi in 15 (16.4%), C. parvum in 3 (3.2%) samples, and a new Cryptosporidium genotype (C. genotype BrPR1) in 3 (3.2%) samples. Cryptosporidium genotype BrPR1 has not yet been classified as a species, and its host spectrum is not known. Cryptosporidium, including zoonotic species, exists at a high prevalence in free-range chickens within the region studied. PMID- 29185603 TI - Influence of biofilm formation on the mechanical properties of enamel after treatment with CPP-ACP creme. AB - The study aimed to investigate the effects of bacterial biofilms on changes in the surface microhardness of enamel treated with casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) with and without fluoride. Human enamel blocks with incipient caries-like lesions were divided into four groups of 13: G1: Saliva (Control); G2: fluoride dentifrice (CrestTM, 1100 ppm as NaF); G3: CPP-ACP (MI Paste; RecaldentTM); and G4: CPP-ACPF (MI Paste Plus; RecaldentTM 900 ppm as NaF). The specimens were soaked in demineralizing solution for 6 h and remineralized in artificial saliva for 18 h alternately for 10 days. The dentifrice was prepared with deionized water in a 1 : 3 ratio (w/w) or applied undiluted in the case of the CPP-ACP group. The surface microhardness (SMH) was evaluated at baseline, after artificial caries, after pH cycling and treatment with dentifrices, and after incubation in media with Streptococcus mutans for biofilm formation. The biofilms were exposed once a day to 2% sucrose and the biofilm viability was measured by MTT reduction. The percentage of change in surface microhardness (%SMHC) was calculated for each block. The data were analyzed by nonparametric test comparisons (alpha = 0.05). The %SMHC values observed in G2 were different from those of G1, G3, and G4 (p < 0.05). After biofilm formation, %SMHC was positive in G2 and G4 when compared to G1 and G3, but resistance to demineralization after biofilm formation was similar in all groups. In conclusion, the presence of biofilms did not influence the treatment outcomes of anticaries products. PMID- 29185604 TI - Glycemic control and adipokines after periodontal therapy in patients with Type 2 diabetes and chronic periodontitis. AB - The mechanism by which chronic periodontitis (CP) affects type 2 diabetes (T2DM) remains unclear. Therefore, the aim of this study is to evaluate the effects of periodontal therapy (PT) on the glycemic control and adipokines of patients with T2DM and CP with the purpose of elucidating the possible mechanisms by which CP influences T2DM. Forty-four patients with T2DM and CP were randomly divided into two groups according to whether they underwent PT. Periodontal status, blood glucose, and the levels of serum tumor necrosis factor alpha (TNF-alpha), interleukin-6 (IL-6), adiponectin (APN), and fibroblast growth factor-21 (FGF-21) were measured at baseline and after 3 months. The results revealed that the probing depth (PD) and attachment loss (AL) were significantly improved, the serum levels of TNF-alpha and IL-6 were significantly decreased, and APN and FGF 21 exhibited substantial increases in the intervention group after 3 months (p < 0.05), whereas no significant changes were observed in the control group. The glycated hemoglobin (HbA1c) levels in both groups decreased significantly after 3 months compared with baseline (p < 0.05), but the intervention group exhibited a significantly greater change (p < 0.05). In conclusion, PT may relieve periodontal inflammation, which causes a reduction of insulin-antagonizing adipokines and an increase in insulin-sensitizing adipokines, thereby eliciting an improvement in glycemic control. PMID- 29185605 TI - The use of tools to support oral lesion description in oral medicine referrals. AB - Poor description of oral lesions jeopardize the prioritization of appointments in Oral Medicine. The present study investigated whether the use of support tools changes the quality of descriptions focusing on health care prioritization. Two oral lesions (A and B) were described by 64 dental students and 48 dentists using three methods: (a) without support tools (free); (b) using the oral examination form from the Specialties Manual in Oral Health/Brazilian Ministry of Health (SMOH form); and (c) using the OralDESC guideline. The descriptions were compared with a gold standard and percentage of agreement was analyzed by the Kruskal Wallis and Dunn's tests (p<0.05). Descriptions with the OralDESC presented higher information quality. Considering items essential for prioritization, the OralDESC demonstrated better performance for lesion A; for lesion B, free descriptions and descriptions using the OralDESC were of higher quality than those using SMOH form. Therefore, the OralDESC offered greater support for the description of oral lesions for health care prioritization in Oral Medicine. PMID- 29185606 TI - The implications of different lateral wall thicknesses on surgical access to the maxillary sinus. AB - The objective of this study was to measure the topographic thickness of the lateral wall of the maxillary sinus in selected Asian populations. Measurements were made on the lateral walls of maxillary sinuses recorded using CBCT in a convenient sample of patients attending an Asian teaching hospital. The points of measurement were the intersections between the axes along the apices of the canine, first premolar, and second premolar and along the mesiobuccal and distobuccal apices of the first and second molars and horizontal planes 10 mm, 20 mm, 30 mm and 40 mm beneath the orbital floor. The CBCT images of 109 patients were reviewed. The mean age of the patients was 33.0 (SD 14.8) years. Almost three quarters (71.8%) of the patients were male. The mean bone thickness decreased beginning at the 10-mm level and continuing to 40 mm below the orbital floor. Few canine regions showed encroachment of the maxillary sinus. The thickness of the buccal wall gradually increased from the canine region (where sinus encroachment of the canine region was present) to the first molar region, after which it decreased to the thickness observed at the canine region. The buccal wall of the maxillary sinus became thicker anteroposteriorly, except in the region of the second molar, and thinner superoinferiorly. These changes will affect the approach used to osteotomize the lateral sinus wall for oral surgery and for the sinus lift procedure.

PMID- 29185608 TI - Basil, tea tree and clove essential oils as analgesics and anaesthetics in Amphiprion clarkii (Bennett, 1830). AB - In this study were evaluated the anaesthesia and analgesic effects of clove Eugenia caryophyllata, tea tree Melaleuca alternifolia and basil Ocimum basilicum essential oils (EO) during handling of yellowtail clownfish Amphiprion clarkii. Juveniles (3.70 +/- 0.75 cm and 1.03 +/- 0.50 g; mean +/- standard deviation) were submitted to concentrations of 40, 50, 60, 70 and 80 ul L-1 of clove, 150, 200, 250, 300 and 350 ul L-1 of basil and 200, 300, 400, 500 and 600 ul L-1 of tea tree oils (n=10/concentration), previously defined in pilot tests. Individually and only once, fish from each treatment were placed in a glass recipient containing 1 L of seawater at a temperature of 25 degrees C, salinity of 35 g L-1 and the specific concentration of diluted EO (stock solution). Control (only seawater) and blank (seawater and ethanol at the highest concentration used to dilute the oils) treatments were also conducted. After reaching the stage of surgical anaesthesia, fish were submitted to biometry and a sensibility test. After that, they were transferred to clean seawater for anaesthesia recovery. The times of induction needed to reach each anaesthesia stage and anaesthesia recovery were recorded. Animals were observed for 72 hours after the procedures. All the EO provoked anaesthesia and analgesic effects in A. clarkii, but basil oil is not recommended because it caused involuntary muscle contractions and mortality in 100% and 12% of fish, respectively. The lower concentrations that promote suitable induction and recovery times are 50 ul L-1 of clove oil and 500 ul L-1 of tea tree oil. However, due to its complementary high analgesic efficiency, clove oil is recommended as the ideal anaesthetic for A. clarkii. PMID- 29185609 TI - Soil macrofauna density and diversity across a chronosequence of tropical forest restoration in Southeastern Brazil. AB - Edaphic macrofauna must be better studied if we want to take advantage of their full potential for the restoration of tropical ecosystems. We investigated changes in edaphic macrofauna density and diversity along a secondary succession chronosequence in the Atlantic Forest. Our results show some clear patterns of change in soil macrofauna along the chronosequence. Density did not increase along secondary succession, but was correlated with canopy cover. Diversity was characterized by high dominance of social insects and evenness among other groups. We conclude soil macrofauna has a high capacity to recolonize young forests and that its recovery is considerably fast compared to other ecosystem transformations. PMID- 29185610 TI - Reproductive dynamics of Lycengraulis grossidens (Clupeiformes: Engraulidae) and Platanichthys platana (Clupeiformes: Clupeidae) in a subtropical coastal lagoon. AB - We evaluated the reproductive dynamics of two fish species, Lycengraulis grossidens and Platanichthys platana, in a subtropical freshwater coastal lagoon (Peri Lagoon) in Brazil. Samples were collected from nine sites every two months from June 2008 to April 2012. Different fishing methods were used to capture larvae, juveniles, and adults. Limnological variables were obtained using multiparameter probe. More females than males were collected of both fish species and the chi-square test (chi2) was used to confirm that the sex ratio was female biased. Large numbers of maturing and mature fishes were observed in almost every sampling month. The gonadosomatic index (GSI) of L. grossidens was the highest in August, October, and December for females and in October for males, and no significant difference was found across years. The GSI of P. platana showed no significant difference across months for either sex; however, significant differences were recorded in year three (June 2010-April 2011) and year four (June 2011-April 2012) for females and in year three (June 2010-April 2011) for males. For both species, GSI was negatively correlated with temperature and water level. L. grossidens larvae were more abundant in October 2010, showing a positive correlation with water transparency, whereas P. platana larvae were more abundant in June 2011, showing a positive correlation with water transparency and negative correlation with temperature and precipitation. Both species were represented by different stages, including larvae, which confirm that these species reproduce in Peri Lagoon. Reproduction was more pronounced in autumn and winter; however, reproductive activity was evident throughout the sampling period. In conclusion, our results show that abiotic factors strongly influence the temporal pattern of reproductive activity and larval assemblages of both L. grossidens and P. platana in Peri Lagoon, Brazil.

PMID- 29185612 TI - Intestinal parasites in cancer patients in the South of Brazil. AB - Intestinal parasitic infections in immunocompromised patients can lead to serious complications when not diagnosed and treated early. This study aimed to investigate the frequency of intestinal parasites in cancer patients undergoing chemotherapy in the South of Brazil. Three fecal samples collected from each patient (73 individuals) were processed by Ritchie and Faust techniques and submitted to specific staining methods for intestinal protozoa. A 61.6% parasite and/or commensal positivity was found. Helminths identified were Ascaris lumbricoides (33.3%), Taenia spp. (6.6%), Strongyloides stercoralis (4.4%) and Trichuris trichiura (2.2%). Among protozoans, Giardia lamblia (26.6%), Cryptosporidium spp. (13.3%) and Cystoisospora belli (4.4%) were identified. The presence of Entamoeba coli, Endolimax nana and Entamoeba hartmanni was also recorded. The results obtained warn of the importance of fecal parasitological diagnosis and the use of specific staining methods for the detection of intestinal parasites in cancer patients. These exams should be regularly requested at the patient's first clinic visit, given the high prevalence found in this study and the possible severity of such conditions for these individuals. PMID- 29185613 TI - Waist Circumference is Associated with Blood Pressure in Children with Normal Body Mass Index: A Cross-Sectional Analysis of 3,417 School Children. AB - BACKGROUND: The prevalence of childhood obesity and associated conditions, such as hypertension, has become a major problem of public health. Although waist circumference (WC) is a marker of cardiovascular risk in adults, it is unclear whether this index is associated with cardiovascular risk factors in children. OBJECTIVE: Our aim was to evaluate the association between increased WC and elevated blood pressure (BP) in children with normal body mass index (BMI) ranges. METHODS: Cross-sectional evaluation of students between 6 and 11 years with normal BMI. WC was categorized by quartile for each age group. Normal BP was defined as values < 90th percentile, and levels above this range were considered elevated. Values of p < 0.05 were considered statistically significant. RESULTS: Of the 5,037 children initially assessed, 404 (8%) were excluded for being underweight and 1,216 (24.1%) were excluded for being overweight or obese. A final sample of 3,417 children was evaluated. The prevalence of elevated BP was 10.7%. In children with WC in the lowest quartile, the prevalence of elevated BP was 8.1%. This prevalence increased in upper quartiles: 10.6% in the second, 12.4% in third and 12.1% in the upper quartile. So, in this group, being in the highest WC quartile was associated with a 57% higher likelihood to present elevated BP when compared to those in the lowest quartile (Q4 vs Q1; OR 1.57 - 95%CI 1.14 - 2.17). CONCLUSION: In children aged 6 to 11 years, increased waist circumference is associated with elevated BP even when BMI is normal. PMID- 29185614 TI - Permanent Pacing After Transcatheter Aortic Valve Implantation: Incidence, Predictors and Evolution of Left Ventricular Function. AB - BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a well-established procedure; however, atrioventricular block requiring permanent pacemaker implantation (PPI) is a common complication. OBJECTIVES: To determine the incidence, predictors and clinical outcomes of PPI after TAVI, focusing on how PPI affects left ventricular ejection fraction (LVEF) after TAVI. METHODS: The Brazilian Multicenter TAVI Registry included 819 patients submitted to TAVI due to severe aortic stenosis from 22 centers from January/2008 to January/2015. After exclusions, the predictors of PPI were assessed in 670 patients by use of multivariate regression. Analysis of the ROC curve was used to measure the ability of the predictors; p < 0.05 was the significance level adopted. RESULTS: Within 30 days from TAVI, 135 patients (20.1%) required PPI. Those patients were older (82.5 vs. 81.1 years; p = 0.047) and mainly of the male sex (59.3% vs 45%; p = 0.003). Hospital length of stay was longer in patients submitted to PPI (mean = 15.7 +/- 25.7 vs. 11.8 +/- 22.9 days; p < 0.001), but PPI affected neither all cause death (26.7% vs. 25.6%; p = 0.80) nor cardiovascular death (14.1% vs. 14.8%; p = 0.84). By use of multivariate analysis, the previous presence of right bundle-branch block (RBBB) (OR, 6.19; 3.56-10.75; p <= 0.001), the use of CoreValve(r) prosthesis (OR, 3.16; 1.74-5.72; p <= 0.001) and baseline transaortic gradient > 50 mm Hg (OR, 1.86; 1.08-3.2; p = 0.025) were predictors of PPI. The estimated risk of PPI ranged from 4%, when none of those predictors was present, to 63%, in the presence of all of them. The model showed good ability to predict the need for PPI: 0.69 (95%CI: 0.64 - 0.74) in the ROC curve. The substudy of 287 echocardiograms during the 1-year follow-up showed worse LVEF course in patients submitted to PPI (p = 0.01). CONCLUSION: BRD previo, gradiente aortico medio > 50 mmHg e CoreValve(r) sao preditores independentes de implante de MPD pos-TAVI. Ocorreu implante de MPD em aproximadamente 20% dos casos de TAVI, o que prolongou a internacao hospitalar, mas nao afetou a mortalidade. O implante de MPD afetou negativamente a FEVE pos-TAVI. PMID- 29185615 TI - Predictors of Total Mortality and Echocardiographic Response for Cardiac Resynchronization Therapy: A Cohort Study. AB - BACKGROUND: Clinical studies demonstrate that up to 40% of patients do not respond to cardiac resynchronization therapy (CRT), thus, appropriate patient selection is critical to the success of CRT in heart failure. OBJECTIVE: Evaluation of mortality predictors and response to CRT in the Brazilian scenario. METHODS: Retrospective cohort study including patients submitted to CRT in a tertiary hospital in southern Brazil from 2008 to 2014. Survival was assessed through a database of the State Department of Health (RS). Predictors of echocardiographic response were evaluated using Poisson regression. Survival analysis was performed by Cox regression and Kaplan Meyer curves. A two-tailed p value less than 0.05 was considered statistically significant. RESULTS: A total of 170 patients with an average follow-up of 1011 +/- 632 days were included. The total mortality was 30%. The independent predictors of mortality were age (hazard ratio [HR] of 1.05, p = 0.027), previous acute myocardial infarction (AMI) (HR of 2.17, p = 0.049) and chronic obstructive pulmonary disease (COPD) (HR of 3.13, p = 0.015). The percentage of biventricular stimulation at 6 months was identified as protective factor of mortality ([HR] 0.97, p = 0.048). The independent predictors associated with the echocardiographic response were absence of mitral insufficiency, presence of left bundle branch block and percentage of biventricular stimulation. CONCLUSION: Mortality in patients submitted to CRT in a tertiary hospital was independently associated with age, presence of COPD and previous AMI. The percentage of biventricular pacing evaluated 6 months after resynchronizer implantation was independently associated with improved survival and echocardiographic response. PMID- 29185616 TI - Incremental Prognostic Value of Conventional Echocardiography in Patients with Acutely Decompensated Heart Failure. AB - BACKGROUND: Acutely decompensated heart failure (ADHF) presents high morbidity and mortality in spite of therapeutic advance. Identifying factors of worst prognosis is important to improve assistance during the hospital phase and follow up after discharge. The use of echocardiography for diagnosis and therapeutic guidance has been of great utility in clinical practice. However, it is not clear if it could also be useful for risk determination and classification in patients with ADHF and if it is capable of adding prognostic value to a clinical score (OPTIMIZE-HF). OBJECTIVE: To identify the echocardiographic variables with independent prognostic value and to test their incremental value to a clinical score. METHODS: Prospective cohort of patients consecutively admitted between January 2013 and January 2015, with diagnosis of acutely decompensated heart failure, followed up to 60 days after discharge. Inclusion criteria were raised plasma level of NT-proBNP (> 450 pg/ml for patients under 50 years of age or NT proBNP > 900 pg/ml for patients over 50 years of age) and at least one of the signs and symptoms: dyspnea at rest, low cardiac output or signs of right-sided HF. The primary outcome was the composite of death and readmission for decompensated heart failure within 60 days. RESULTS: Study participants included 110 individuals with average age of 68 +/- 16 years, 55% male. The most frequent causes of decompensation (51%) were transgression of the diet and irregular use of medication. Reduced ejection fraction (<40%) was present in 47% of cases, and the NT-proBNP median was 3947 (IIQ = 2370 to 7000). In multivariate analysis, out of the 16 echocardiographic variables studied, only pulmonary artery systolic pressure remained as an independent predictor, but it did not significantly increment the C-statistic of the OPTMIZE-HF score. CONCLUSION: The addition of echocardiographic variables to the OPTIMIZE-HF score, with the exception of left ventricular ejection fraction, did not improve its prognostic accuracy concerning cardiovascular events (death or readmission) within 60 days.

AB - The best approach of multivessel coronary artery disease in the context of acute myocardial infarction with ST segment elevation and primary percutaneous coronary intervention is one of the main reasons for controversy in cardiology. Although the main global guidelines do not recommend routine complete revascularization in these patients, recent randomized clinical trials have demonstrated benefit of this approach in reducing cardiovascular outcomes. For this reason, an adequate review of this evidence is essential in order to establish scientifically based strategy and achieve better outcomes for these patients who present with acute myocardial infarction. This review aims to present objectively the most recent evidence available on this topic. PMID- 29185619 TI - IN TIME: PUBLONS SEEKS TO ATTRACT REVIEWERS AND IMPROVE PEER REVIEW. PMID- 29185620 TI - USE OF SCORE AND CEREBROSPINAL FLUID LACTATE DOSAGE IN DIFFERENTIAL DIAGNOSIS OF BACTERIAL AND ASEPTIC MENINGITIS. AB - OBJECTIVE: To evaluate Bacterial Meningitis Score (BMS) on its own and in association with Cerebrospinal Fluid (CSF) lactate dosage in order to distinguish bacterial from aseptic meningitis. METHODS: Children diagnosed with meningitis at a tertiary hospital between January/2011 and December/2014 were selected. All data were obtained upon admission. BMS was applied and included: CSF Gram staining (2 points); CSF neutrophil count >=1,000 cells/mm3 (1 point); CSF protein >=80 mg/dL (1 point); peripheral blood neutrophil count >=10,000 cells/mm3 (1 point) and seizures upon/before arrival (1 point). Cutoff value for CSF lactate was >=30 mg/dL. Sensitivity, specificity and negative predictive value of several BMS cutoffs and BMS associated with high CSF lactate were evaluated for prediction of bacterial meningitis. RESULTS: Among 439 eligible patients, 94 did not have all data available to complete the score, and 345 patients were included: 7 in bacterial meningitis group and 338 in aseptic meningitis group. As predictive factors of bacterial meningitis, BMS >=1 had 100% sensitivity (95%CI 47.3-100), 64.2% specificity (58.8-100) and 100% negative predictive value (97.5-100); BMS >=2 or BMS >=1 associated with high CSF lactate also showed 100% sensitivity (47.3-100); but 98.5% specificity (96.6-99.5) and 100% negative predictive value (98.3-100). CONCLUSIONS: 2 point BMS in association with CSF lactate dosage had the same sensitivity and negative predictive value, with increased specificity for diagnosis of bacterial meningitis when compared with 1-point BMS. PMID- 29185621 TI - THERAPEUTIC APPROACH AND ITS RELATIONSHIP WITH SOCIAL AND ECONOMIC CHARACTERISTICS OF USERS OF CENTERS FOR PSYCHOSOCIAL CARE FOR CHILDREN AND ADOLESCENTS. AB - OBJECTIVE: To analyze the therapeutic approach and its relationship with the economic and social characteristics and the care of children in Centers for Psychosocial Attention. METHODS: Descriptive study with a sample of 294 children monitored in two Centers for Psychosocial Attention to Children and Adolescents in Fortaleza, Ceara, Northeast Brazil. The study was conducted from February to December, 2012. Participants were accompanied by their parents or caregivers. Data were collected in a structured questionnaire containing social, economic and care variables. The bivariate analysis used the chi2 test to test the association between variables. RESULTS: In this study, 292 children aged 3-12 were selected, following the order of attendance at the service, most of them male (74.3%) and belonging to social classes D and E (89.3%). The most frequent diagnosis referred to by the caregivers was mental disorders. Three different therapeutic approaches were identified: pharmacological approach (44.5%); non-pharmacological approach (11.6%); association of both techniques (43.8%). For all therapeutic approaches, there was association with the variable living situation (p=0.021), as well as with the variables, "improving" with the treatment (p=0.002) and "problems" with the treatment (p=0,004). CONCLUSIONS: It was possible to highlight that the associated therapeutic approach (pharmacological and non-pharmacological treatment) provides more benefits to children. Therefore, associating the medicines to the psychotherapeutic practices may be recommended as a strategy in the mental health policy directed to children and adolescents. PMID- 29185622 TI - MILK CONSUMPTION IN INFANTS UNDER ONE YEAR OF AGE AND VARIABLES ASSOCIATED WITH NON-MATERNAL MILK CONSUMPTION. AB - OBJECTIVE: To verify the type of milk consumed by children under one year of age and identify variables associated with non-maternal milk consumption (formula or cow milk). METHODS: Cross-sectional study developed during the 2012 National Vaccination Campaign against Poliomyelitis. The companions of 935 children under one year of age answered a structured questionnaire on the child's diet in the last 24 hours. The estimates are presented by points, with 95%CI. F-statistics were used to check for differences in the proportion of the types of milk consumption according to the children's age range (<6 months and 6-11 months) and the association between non-maternal milk consumption and the study variables. RESULTS: The consumption of maternal milk and child formula was higher for children under six months of age - corresponding to 82.8% (95%CI 78.5-86.3) and 70.4% (95%CI 61.4-78.0), respectively -, whereas the consumption of cow milk was higher among children between 6 and 11 months of age - 74.2% (95%CI 66.5-80.6) -, with differences in the consumption proportions (p<0.0001). The variables associated with higher cow milk consumption were lower maternal education (p<0.0001), the fact that the mother does not have a paid occupation (p=0.0015), child doctor's appointment in the public health network (p<0.0001) and participation in the Child's Milk Program (p<0.0001). CONCLUSIONS: The infants received cow's milk early (before the first year of life), especially children from families with lower socioeconomic levels and children who took part in a specific social program for milk distribuition. PMID- 29185623 TI - QUALITY OF LIFE AND HEALTH SELF-PERCEPTION IN CHILDREN WITH POOR SCHOOL PERFORMANCE. AB - OBJECTIVE: To examine the association between quality of life and health self perception of children with poor school performance, considering sociodemographic factors. METHODS: An analytical, observational, cross-sectional study was conducted with 99 children aged 7 to 12 years receiving specialized educational assistance. Parents and legal guardians answered questions concerning the sociodemographic profile. For an assessment of the quality of life and proposed domains (autonomy, functioning, leisure, and family), the children completed the Autoquestionnarie Qualite de Vie Enfant Image (AUQEI) and answered a question concerning their self-perceived health. Data were analyzed using multiple linear regression, considering a 5% significance level. RESULTS: Among the evaluated children, 69 (69.7%) male participants with mean age of 8.7+/-1.5, 27% self assessed their health status as poor/very poor, and 36.4% of the children reported having impaired quality of life. As for the domains assessed by AUQEI, there was statistical significance in the associations between family with age, autonomy with economic classification, and leisure and functioning with self perceived health. CONCLUSIONS: The quality of life of children with academic underachievement is associated with their health self-perception and sociodemographic characteristics. PMID- 29185624 TI - THE EFFECT OF ADAPTED SPORTS IN QUALITY OF LIFE AND BIOPSYCHOSOCIAL PROFILE OF CHILDREN AND ADOLESCENTS WITH CEREBRAL PALSY. AB - OBJECTIVE: The participation in sports and recreational activities promotes inclusion and the quality of life (QOL) for people with some type of disability. This study aims to evaluate and describe the effect of adapted sports (AS) on the QOL and biopsychosocial profile of children/adolescents with cerebral palsy (CP). METHODS: Forty-seven children/adolescents with CP were evaluated and referred to AS (soccer and swimming). The QOL was evaluated by the Pediatric Outcome Data Collection Instrument (PODCI) and the biopsychosocial profile by the Behavior Checklist for Children/Adolescents (CBCL). These instruments considered the influence of gender, age, race, social income, education and topography of spasticity. RESULTS: Seventeen children/adolescents who practiced AS were re evaluated after one year. There was significant improvement in the dimensions of transfers and mobility (p=0.009), upper extremity function (p=0.021) and global function (p=0.004) of IARRP. There was significant improvement considering the attention disorder syndrome (p=0.026), and the attention deficit hyperactivity disorders (p=0.008) in the Diagnostic and Statistical Manual of Mental Disorders (DSM)-oriented analysis (CBCL). Children/adolescents with diplegia obtained greater benefit than those with hemiplegia in relation to the comfort and pain (p=0.02) and global dimension (p=0.027) (PODCI). The boys had higher scores in total competence (p=0.048); the extremely poor group obtained higher levels in the breaking rules syndrome (p=0.008). CONCLUSIONS: The AS had a positive effect on the QOL and biopsychosocial profile of children/adolescents with CP in this sample, especially considering the global and upper extremity function, capacity for transfers and mobility, and benefits in the problems related to difficulties in attention. PMID- 29185625 TI - UNUSUAL WARFARIN DOSE TO ACHIEVE THERAPEUTIC INR IN A 4-MONTH OLD CHILD: NON GENETICS RISK FACTORS ARE STILL A CHALLENGE. AB - OBJECTIVE: To report a case of a 4-month old girl that required 0.7 mg/kg/day (5 mg) of warfarin and discuss relevant risk factors for requiring higher doses. CASE DESCRIPTION: In November 2015, a 5 kg female infant (36-week preterm) was admitted to the hospital due to status epilepticus and fever. Diazepam, phenytoin and ceftriaxone were prescribed. Cerebrospinal fluid contained 7 leukocytes, 150 mg/dL proteins, 1 mg/dL glucose and gram positive cocci were observed. Cranial tomography suggested hypodense signs in the cerebellum, right temporal lobe and left basal nuclei, which was consistent with pneumococcal meningitis-induced infectious vasculitis. She required low molecular weight heparin and warfarin for post-encephalitis thrombosis. About 10 days were required to achieve therapeutic INR, and warfarin was adjusted five times since the initial prescription. COMMENTS: The risk factors for higher warfarin doses were age and enteral tube feeding. Phenobarbital and prednisone might also have contributed with one of the highest warfarin dose ever reported. Despite current importance given to genetics testing, clinicians should attempt to identify common contributing factors for prolonged non-therapeutic INR, to minimize the risk of coagulation, and to reduce costs of hospital stay and laboratory exams. PMID- 29185626 TI - Do resources buffer the prospective association of psychosocial work stress with depression? Longitudinal evidence from ageing workers. AB - Objectives There is now convincing evidence that psychosocial work stressors are linked to depression. Few studies, however, have tested if individual resources can buffer the longitudinal effects of psychosocial work stressors on depressive symptoms. This study investigates how two types of resources (internal and external resources) affect the association between psychosocial work stressors and depressive symptoms. Methods Data were obtained from the US Health and Retirement Study, with baseline information on psychosocial work stressors [job strain and effort-reward imbalance (ERI)] and on internal ("high mastery" and "low constraints") and external resources ("private social support") among initially healthy workers. This information was linked to elevated depressive symptoms two years later. The sample includes 5473 observations and we report relative risks (RR) and effect modification on the additive and multiplicative scale. Results Psychosocial stressors and low resources (internal and external) were both independently related to depressive symptoms. Individuals with both, psychosocial stressors and low resources, had the highest risk of developing elevated depressive symptoms (eg, RR ERI-LowMastery3.32, 95% CI 2.49-4.42; RR JobStrain-LowMastery2.89, 95% CI 2.18-3.84). Yet, based on interaction analyses, only social support from friends buffered the association between work stressors and depressive symptoms. Conclusions Our findings have demonstrated that psychosocial stressors at work are related to mental health, and that in most cases this relationship holds true both for people with high and with low resources. Therefore, there is no clear indication that internal or external resources buffer the association between psychosocial work stressors and depressive symptoms. PMID- 29185628 TI - ? PMID- 29185627 TI - Strategies for enhancing the implementation of school-based policies or practices targeting risk factors for chronic disease. AB - BACKGROUND: A number of school-based policies or practices have been found to be effective in improving child diet and physical activity, and preventing excessive weight gain, tobacco or harmful alcohol use. Schools, however, frequently fail to implement such evidence-based interventions. OBJECTIVES: The primary aims of the review are to examine the effectiveness of strategies aiming to improve the implementation of school-based policies, programs or practices to address child diet, physical activity, obesity, tobacco or alcohol use.Secondary objectives of the review are to: Examine the effectiveness of implementation strategies on health behaviour (e.g. fruit and vegetable consumption) and anthropometric outcomes (e.g. BMI, weight); describe the impact of such strategies on the knowledge, skills or attitudes of school staff involved in implementing health promoting policies, programs or practices; describe the cost or cost effectiveness of such strategies; and describe any unintended adverse effects of strategies on schools, school staff or children. SEARCH METHODS: All electronic databases were searched on 16 July 2017 for studies published up to 31 August 2016. We searched the following electronic databases: Cochrane Library including the Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; MEDLINE In Process & Other Non-Indexed Citations; Embase Classic and Embase; PsycINFO; Education Resource Information Center (ERIC); Cumulative Index to Nursing and Allied Health Literature (CINAHL); Dissertations and Theses; and SCOPUS. We screened reference lists of all included trials for citations of other potentially relevant trials. We handsearched all publications between 2011 and 2016 in two specialty journals (Implementation Science and Journal of Translational Behavioral Medicine) and conducted searches of the WHO International Clinical Trials Registry Platform (ICTRP) (http://apps.who.int/trialsearch/) as well as the US National Institutes of Health registry (https://clinicaltrials.gov). We consulted with experts in the field to identify other relevant research. SELECTION CRITERIA: 'Implementation' was defined as the use of strategies to adopt and integrate evidence-based health interventions and to change practice patterns within specific settings. We included any trial (randomised or non-randomised) conducted at any scale, with a parallel control group that compared a strategy to implement policies or practices to address diet, physical activity, overweight or obesity, tobacco or alcohol use by school staff to 'no intervention', 'usual' practice or a different implementation strategy. DATA COLLECTION AND ANALYSIS: Citation screening, data extraction and assessment of risk of bias was performed by review authors in pairs. Disagreements between review authors were resolved via consensus, or if required, by a third author. Considerable trial heterogeneity precluded meta analysis. We narratively synthesised trial findings by describing the effect size of the primary outcome measure for policy or practice implementation (or the median of such measures where a single primary outcome was not stated). MAIN RESULTS: We included 27 trials, 18 of which were conducted in the USA. Nineteen studies employed randomised controlled trial (RCT) designs. Fifteen trials tested strategies to implement healthy eating policies, practice or programs; six trials tested strategies targeting physical activity policies or practices; and three trials targeted tobacco policies or practices. Three trials targeted a combination of risk factors. None of the included trials sought to increase the implementation of interventions to delay initiation or reduce the consumption of alcohol. All trials examined multi-strategic implementation strategies and no two trials examined the same combinations of implementation strategies. The most common implementation strategies included educational materials, educational outreach and educational meetings. For all outcomes, the overall quality of evidence was very low and the risk of bias was high for the majority of trials for detection and performance bias.Among 13 trials reporting dichotomous implementation outcomes-the proportion of schools or school staff (e.g. classes) implementing a targeted policy or practice-the median unadjusted (improvement) effect sizes ranged from 8.5% to 66.6%. Of seven trials reporting the percentage of a practice, program or policy that had been implemented, the median unadjusted effect (improvement), relative to the control ranged from -8% to 43%. The effect, relative to control, reported in two trials assessing the impact of implementation strategies on the time per week teachers spent delivering targeted policies or practices ranged from 26.6 to 54.9 minutes per week. Among trials reporting other continuous implementation outcomes, findings were mixed. Four trials were conducted of strategies that sought to achieve implementation 'at scale', that is, across samples of at least 50 schools, of which improvements in implementation were reported in three trials.The impact of interventions on student health behaviour or weight status were mixed. Three of the eight trials with physical activity outcomes reported no significant improvements. Two trials reported reductions in tobacco use among intervention relative to control. Seven of nine trials reported no between-group differences on student overweight, obesity or adiposity. Positive improvements in child dietary intake were generally reported among trials reporting these outcomes. Three trials assessed the impact of implementation strategies on the attitudes of school staff and found mixed effects. Two trials specified in the study methods an assessment of potential unintended adverse effects, of which, they reported none. One trial reported implementation support did not significantly increase school revenue or expenses and another, conducted a formal economic evaluation, reporting the intervention to be cost-effective. Trial heterogeneity, and the lack of consistent terminology describing implementation strategies, were important limitations of the review. AUTHORS' CONCLUSIONS: Given the very low quality of the available evidence, it is uncertain whether the strategies tested improve implementation of the targeted school-based policies or practices, student health behaviours, or the knowledge or attitudes of school staff. It is also uncertain if strategies to improve implementation are cost-effective or if they result in unintended adverse consequences. Further research is required to guide efforts to facilitate the translation of evidence into practice in this setting.

Recently, the endovesical administration of a combined regimen using a cytostatic agent and microwave induced hyperthermia appears to be highly efficient and possibly superior to intravesical chemotherapy alone for none invasive bladder cancer.

AB - The NHS in the UK is under increasing pressure as a result of financial and recruitment issues, as well as an ageing population. Nursing has continued to adapt to this challenging time. Over the past few years, the advanced nurse practitioner (ANP) role has been implemented widely in primary and secondary care. However, the ANP role has lacked consistency in scope of practice, training and regulation. This article summarises the development of the ANP role in the UK and internationally, and issues relating to regulation. Globally, ANPs are regulated by one of three different bodies: nationally by central government or a professional body, or locally by employers. In the UK, the role is regulated by local procedures, relying on employers to make decisions about the scope and preparation for practice. Some of the challenges in the UK in relation to ANP regulation are discussed, including variations in scope, organisational constraints and lack of support. These challenges are exacerbated by a lack of role clarity, thereby indicating there is a need to improve regulation of ANPs. The Royal College of Nursing has responded to these challenges by introducing 'credentialing', a system for recording qualifications, skills and experience, but the uptake of this process is yet to be evaluated. Therefore, employers and ANPs should be aware of their collective responsibility for ensuring appropriate role regulation.

AB - Patients who deteriorate without recognition or timely interventions are at risk of critical care admission and increased morbidity or mortality. This article outlines the systematic ABCDE (airway, breathing, circulation, disability, exposure) approach to patient assessment, which enables healthcare practitioners to identify and respond to life-threatening conditions in order of priority. The patient's vital signs should be measured as part of the ABCDE assessment and recorded using a track and trigger tool to enhance recognition of physiological abnormalities that signal deterioration. To optimise communication and escalation of deteriorating patients, healthcare practitioners should report ABCDE assessment findings using a structured communication tool.

AB - Fuel treatment implementation in dry forest types throughout the western UnitedStates is likely to increase in pace and scale in response to increasing incidence of large wildfires.While it is clear that properly implemented fuel treatments are effective at reducing hazardousfire potential, there are ancillary ecological effects that can impact forest resilience eitherpositively or negatively depending on the specific elements examined, as well as treatment type,timing, and intensity. In this study, we use overstory tree growth responses, measured sevenyears after the most common fuel treatments, to estimate forest health. Across the five speciesanalyzed, observed mortality and future vulnerability were consistently low in the mechanical-only treatment. Fire-only was similar to the control for all species except Douglas-fir, whilemechanical plus-fire had high observed mortality and future vulnerability for white fir and sugarpine. Given that overstory trees largely dictate the function of forests and services they provide(e.g., wildlife habitat, carbon sequestration, soil stability) these results have implications forunderstanding longer-term impacts of common fuel treatments on forest resilience. PMID- 29185660 TI - Are biological communities in naturally unproductive streams resistant to additional anthropogenic stressors? AB - Studies on the interactive responses to multiple simultaneously acting stressors have focused on individual or population-level responses in laboratory microcosms, while field-based studies on community-level responses are rare. We examined the influence of a natural (non-anthropogenic acidity) vs. human-induced stress (land drainage) and their interaction on species richness and spatial turnover (beta diversity) of stream diatom, bryophyte, and benthic invertebrate communities. Our four stream categories were: circumneutral reference, circumneutral impacted, naturally acidic, and naturally acidic impacted streams. We expected the most sensitive species to be present only in the circumneutral reference streams. Therefore, species richness should be highest in these streams and lowest in the naturally acidic streams additionally stressed by forest drainage. Alternatively, communities in acidic streams may consist of the most tolerant taxa that are unaffected by further stressors, species richness in these streams remaining unaffected by drainage. We also expected spatial turnover to be highest in the circumneutral near-pristine streams and lowest in the drainage impacted acidic streams. In all three taxonomic groups, alpha diversity was lower in the naturally acidic than in circumneutral streams. The additional impact of the anthropogenic stress on species richness varied between groups, having no effect on diatoms, antagonistic effect on bryophytes, and additive effect on invertebrates. We also found differences in how each stressor modified beta diversity of each taxonomic group. For diatoms, beta diversity showed an overall tendency to decrease with increasing stress level, while bryophyte beta diversity responded mainly to forest drainage. Benthic invertebrate beta diversity did not differ between treatments. Our results suggest that non-additive effects among stressors need special attention to improve the understanding and management of multifactor responses in streams. Our results also argue for the primacy of a multi-taxon approach to environmental impact detection, and for the inclusion of a wide array of ecological responses, particularly community turnover, in bioassessment programs to detect responses that may go unnoticed by conventional richness-based measures. PMID- 29185661 TI - Is U.S. climatic diversity well represented within the existing federal protection network? AB - Establishing protection networks to ensure that biodiversity and associated ecosystem services persist under changing environments is a major challenge for conservation planning. The potential consequences of altered climates for the structure and function of ecosystems necessitates new and complementary approaches be incorporated into traditional conservation plans. The conterminous United States of America (CONUS) has an extensive system of protected areas managed by federal agencies, but a comprehensive assessment of how this network represents CONUS climate is lacking. We present a quantitative classification of the climate space that is independent from the geographic locations to evaluate the climatic representation of the existing protected area network. We use this classification to evaluate the coverage of each agency's jurisdiction and to identify current conservation deficits. Our findings reveal that the existing network poorly represents CONUS climatic diversity. Although rare climates are generally well represented by the network, the most common climates are particularly underrepresented. Overall, 83% of the area of the CONUS corresponds to climates underrepresented by the network. The addition of some currently unprotected federal lands to the network would enhance the coverage of CONUS climates. However, to fully palliate current conservation deficits, large-scale private-land conservation initiatives will be critical. PMID- 29185662 TI - Dry forest resilience varies under simulated climate-management scenarios in a central Oregon, USA landscape. AB - Determining appropriate actions to create or maintain landscapes resilient to climate change is challenging because of uncertainty associated with potential effects of climate change and their interactions with land management. We used a set of climate-informed state-and-transition models to explore the effects of management and natural disturbances on vegetation composition and structure under different future climates. Models were run for dry forests of central Oregon under a fire suppression scenario (i.e., no management other than the continued suppression of wildfires) and an active management scenario characterized by light to moderate thinning from below and some prescribed fire, planting, and salvage logging. Without climate change, area in dry province forest types remained constant. With climate change, dry mixed-conifer forests increased in area (by an average of 21-26% by 2100), and moist mixed-conifer forests decreased in area (by an average of 36-60% by 2100), under both management scenarios. Average area in dry mixed-conifer forests varied little by management scenario, but potential decreases in the moist mixed-conifer forest were lower with active management. With changing climate in the dry province of central Oregon, our results suggest the likelihood of sustaining current levels of dense, moist mixed conifer forests with large-diameter, old trees is low (less than a 10% chance) irrespective of management scenario; an opposite trend was observed under no climate change simulations. However, results also suggest active management within the dry and moist mixed-conifer forests that creates less dense forest conditions can increase the persistence of larger-diameter, older trees across the landscape. Owing to projected increases in wildfire, our results also suggest future distributions of tree structures will differ from the present. Overall, our projections indicate proactive management can increase forest resilience and sustain some societal values, particularly in drier forest types. However, opportunities to create more disturbance-adapted systems are finite, all values likely cannot be sustained at current levels, and levels of resilience success will likely vary by dry province forest type. Land managers planning for a future without climate change may be assuming a future that is unlikely to exist. PMID- 29185663 TI - Effects of climate and nutrient load on the water quality of shallow lakes assessed through ensemble runs by PCLake. AB - Complex ecological models are used to predict the consequences of anticipated future changes in climate and nutrient loading for lake water quality. These models may, however, suffer from nonuniqueness in that various sets of model parameter values may yield equally satisfactory representations of the system being modeled, but when applied in future scenarios these sets of values may divert considerably in their simulated outcomes. Compilation of an ensemble of model runs allows us to account for simulation variability arising from model parameter estimates. Thus, we propose a new approach for aquatic ecological models creating a more robust prediction of future water quality. We used our ensemble approach in an application of the widely used PCLake model for Danish shallow Lake Arreskov, which during the past two decades has demonstrated frequent shifts between turbid and clear water states. Despite marked variability, the span of our ensemble runs encapsulated 70-90% of the observed variation in lake water quality. The model exercise demonstrates that future warming and increased nutrient loading lead to lower probability of a clear water, vegetation-rich state and greater likelihood of cyanobacteria dominance. In a 6.0 degrees C warming scenario, for instance, the current nutrient loading of nitrogen and phosphorus must be reduced by about 75% to maintain the present ecological state of Lake Arreskov, but even in a near-future 2.0 degrees C warming scenario, a higher probability of a turbid, cyanobacteria-dominated state is predicted. As managers may wish to determine the probability of achieving a certain ecological state, our proposed ensemble approach facilitates new ways of communicating future stressor impacts. PMID- 29185665 TI - Groundwater availability mediates the ecosystem effects of an invasion of Prosopis pallida. AB - Groundwater levels in arid environments are dropping worldwide due to human extraction, and precipitation events are predicted to become rarer and more intense in many arid areas with global climate change. These changes will likely alter both primary productivity and plant-soil nutrient cycles. To better understand the nature of such alterations, we examined effects of groundwater availability on plant-soil nitrogen (N) cycling in areas invaded by the N-fixing phreatophyte, Prosopis pallida, on the dry leeward coast of Hawai'i Island. Our aims were to quantify effects of groundwater availability to P. pallida on rates of litterfall N inputs and accretion in soils and to quantify effects of groundwater availability on N mineralization and leaching rates of inorganic N under natural rainfall conditions and simulated rain events. Stem water delta18O values indicate that P. pallida trees in lowland plots accessed shallow groundwater, while in upland plots they relied solely on rainfall. During drought periods, P. pallida at upland plots experienced water stress, evidenced by lower stem water potentials, higher water-use efficiency, and lower predawn photosynthetic performance than at lowland plots. Prosopis pallida basal area was 5.3 times greater at lowland plots, and these plots exhibited 17 times higher carbon (C), 24 times higher N, and 35 times higher phosphorus (P) additions via litterfall, indicating that productivity of this phreatophyte was decoupled from rainfall where groundwater was present. Total N mass in soils was 4.7 times greater where groundwater was accessible, supporting the case that groundwater access increased N2 fixation at a stand level. In contrast, N mineralization and leaching losses from soils, though substantially greater in lowland relative to upland areas, were strongly controlled by rainfall. Results provide clear examples of how invasive species with particular functional attributes (i.e., N fixing phreatophytes) exploit otherwise inaccessible resources to dramatically alter the functioning of the systems they invade and how anthropogenic changes to hydrological processes can also alter ecosystem-level impacts of biological invasions. Results also illustrate a mechanism by which regional groundwater drawdown may reduce soil nutrient accretion and availability in arid regions. PMID- 29185664 TI - Agrochemicals indirectly increase survival of E. coli O157:H7 and indicator bacteria by reducing ecosystem services. AB - Storm water and agricultural runoff frequently contain agrochemicals, fecal indicator bacteria (FIB), and zoonotic pathogens. Entry of such contaminants into aquatic ecosystems may affect ecology and human health. This study tested the hypothesis that the herbicide atrazine and the fungicide chlorothalonil indirectly affect the survival of FIB (Escherichia coli and Enterococcus faecalis) and a pathogen (E. coli O157:H7) by altering densities of protozoan predators or by altering competition from autochthonous bacteria. Streptomycin resistant E. coli, En. faecalis, and E. coli O157:H7 were added to microcosms composed of Florida river water containing natural protozoan and bacterial populations. FIB, pathogen, and protozoan densities were monitored over six days. Known metabolic inhibitors, cycloheximide and streptomycin, were used to inhibit autochthonous protozoa or bacteria, respectively. The inhibitors made it possible to isolate the effects of predation or competition on survival of allochthonous bacteria, and each treatment increased the survival of FIB and pathogens. Chlorothalonil's effect was similar to that of cycloheximide, significantly reducing protozoan densities and elevating densities of FIB and pathogens relative to the control. Atrazine treatment did not affect protozoan densities, but, through an effect on competition, resulted in significantly greater densities of En. faecalis and E. coli O157:H7. Hence, by reducing predaceous protozoa and bacterial competitors that facilitate purifying water bodies of FIBs and human pathogens, chlorothalonil and atrazine indirectly diminished an ecosystem service of fresh water. PMID- 29185666 TI - Limitations of extrapolating toxic effects on reproduction to the population level. AB - For the ecological risk assessment of toxic chemicals, standardized tests on individuals are often used as proxies for population-level effects. Here, we address the utility of one commonly used metric, reproductive output, as a proxy for population-level effects. Because reproduction integrates the outcome of many interacting processes (e.g., feeding, growth, allocation of energy to reproduction), the observed toxic effects in a reproduction test could be due to stress on one of many processes. Although this makes reproduction a robust endpoint for detecting stress, it may mask important population-level consequences if the different physiological processes stress affects are associated with different feedback mechanisms at the population level. We therefore evaluated how an observed reduction in reproduction found in a standard reproduction test translates to effects at the population level if it is caused by hypothetical toxicants affecting different physiological processes (physiological modes of action; PMoA). For this we used two consumer-resource models: the Yodzis-Innes (YI) model, which is mathematically tractable, but requires strong assumptions of energetic equivalence among individuals as they progress through ontogeny, and an individual-based implementation of dynamic energy budget theory (DEB-IBM), which relaxes these assumptions at the expense of tractability. We identified two important feedback mechanisms controlling the link between individual- and population-level stress in the YI model. These mechanisms turned out to also be important for interpreting some of the individual-based model results; for two PMoAs, they determined the population response to stress in both models. In contrast, others stress types involved more complex feedbacks, because they asymmetrically stressed the production efficiency of reproduction and somatic growth. The feedbacks associated with different PMoAs drastically altered the link between individual- and population-level effects. For example, hypothetical stressors with different PMoAs that had equal effects on reproduction had effects ranging from a negligible decline in biomass to population extinction. Thus, reproduction tests alone are of little use for extrapolating toxicity to the population level, but we showed that the ecological relevance of standard tests could easily be improved if growth is measured along with reproduction. PMID- 29185667 TI - Aboveground biomass mapping of African forest mosaics using canopy texture analysis: toward a regional approach. AB - In the context of the reduction of greenhouse gas emissions caused by deforestation and forest degradation (the REDD+ program), optical very high resolution (VHR) satellite images provide an opportunity to characterize forest canopy structure and to quantify aboveground biomass (AGB) at less expense than methods based on airborne remote sensing data. Among the methods for processing these VHR images, Fourier textural ordination (FOTO) presents a good method to detect forest canopy structural heterogeneity and therefore to predict AGB variations. Notably, the method does not saturate at intermediate AGB values as do pixelwise processing of available space borne optical and radar signals. However, a regional-scale application requires overcoming two difficulties: (1) instrumental effects due to variations in sun-scene-sensor geometry or sensor specific responses that preclude the use of wide arrays of images acquired under heterogeneous conditions and (2) forest structural diversity including monodominant or open canopy forests, which are of particular importance in Central Africa. In this study, we demonstrate the feasibility of a rigorous regional study of canopy texture by harmonizing FOTO indices of images acquired from two different sensors (Geoeye-1 and QuickBird-2) and different sun-scene sensor geometries and by calibrating a piecewise biomass inversion model using 26 inventory plots (1 ha) sampled across very heterogeneous forest types. A good agreement was found between observed and predicted AGB (residual standard error [RSE] = 15%; R2 = 0.85; P < 0.001) across a wide range of AGB levels from 26 Mg/ha to 460 Mg/ha, and was confirmed by cross validation. A high-resolution biomass map (100-m pixels) was produced for a 400-km2 area, and predictions obtained from both imagery sources were consistent with each other (r = 0.86; slope = 1.03; intercept = 12.01 Mg/ha). These results highlight the horizontal structure of forest canopy as a powerful descriptor of the entire forest stand structure and heterogeneity. In particular, we show that quantitative metrics resulting from such textural analysis offer new opportunities to characterize the spatial and temporal variation of the structure of dense forests and may complement the toolbox used by tropical forest ecologists, managers or REDD+ national monitoring, reporting and verification bodies. PMID- 29185668 TI - Long-term monitoring reveals differing impacts of elephants on elements of a canopy shrub community. AB - The conservation management of southern Africa's elephants focuses on identifying and mitigating the extent and intensity of impacts on biological diversity. However, variation in the intensity of elephant effects between elements of biodiversity is seldom explored, which limits our ability to interpret the scale of the impacts. Our study quantifies >50 years of impacts in the succulent thickets of the Addo Elephant National Park, South Africa, contrasting hypotheses for the resilience of the canopy shrubs (a key functional guild) to elephants with those that argue the opposite. We also assess the impacts between elements of the community, ranging from community composition and structure to the structure of individual canopy species. We show the vulnerability of the canopy shrubs to transformation as the accumulated influences of elephants alter community composition and structure. The pattern of transformation is similar to that caused by domestic herbivores, which leads us to predict that elephants will eventually bring about landscape-level degradation and a significant loss of biodiversity. While we expected the canopy species to show similar declining trends in structure, providing insight into the response of the community as a whole, we demonstrate an uneven distribution of impacts between constituent elements; most of the canopy dominants exhibited little change, resisting removal. This implies that these canopy dominants might not be useful indicators of community change in thickets, a pattern that is likely repeated among the canopy trees of savanna systems. Our findings suggest that predicting elephant impacts, and finding solutions to the so-called "elephant problem," require a broader and more integrated understanding of the mechanisms driving the changes between elements of biodiversity at various spatial and temporal scales. PMID- 29185669 TI - Habitat- and rainfall-dependent biodiversity responses to cattle removal in an arid woodland-grassland environment. AB - Biodiversity conservation in rangeland environments is often addressed by removing livestock, but inconsistent responses by biota mean that the efficacy of this form of management is hotly debated. Reasons for this inconsistency include the usually short duration and small spatial scale of manipulations compared to the area of grazing properties, as well as divergent responses amongst biota. In low-productivity arid environments, the pulse-reserve dynamic also complicates the outcome of manipulations. Here, we tested and extended these ideas in a heterogeneous desert environment in central Australia that consists of small patches of open woodland (gidgee) in a grassland (spinifex) matrix. Taking advantage of a controlled property-scale removal of cattle, and a rain event that stimulated productivity, we first quantified differences in the vegetation and small vertebrates of these two habitats, and then tracked the diversity, composition, and abundance of these biota for 6-19 months post-rain. We predicted that the two habitats would differ in the structure, composition, and reproductive output of their constituent plant species. We predicted also that the effects of cattle removal would interact with these habitat differences, with the abundance, richness, and diversity of small mammals and reptiles differing across habitats and grazing treatments. As anticipated, plant species composition in woodland was distinct from that in grassland and varied over time. The effects of cattle removal were habitat specific: Plant composition responded to de stocking in woodland, but not in grassland; flowers were more abundant, and palatable plant cover also was greater following cessation of grazing pressure. The responses of small mammals but not reptiles showed some accord with our predictions, varying over time but inconsistently with treatment, and perhaps reflected high variability in capture success. We conclude that the timing and length of sampling are important when evaluating the responses of biota to livestock removal, as is the inclusion of all key habitats in the sampling regime. PMID- 29185670 TI - Selective-logging and oil palm: multitaxon impacts, biodiversity indicators, and trade-offs for conservation planning. AB - Strong global demand for tropical timber and agricultural products has driven large-scale logging and subsequent conversion of tropical forests. Given that the majority of tropical landscapes have been or will likely be logged, the protection of biodiversity within tropical forests thus depends on whether species can persist in these economically exploited lands, and if species cannot persist, whether we can protect enough primary forest from logging and conversion. However, our knowledge of the impact of logging and conversion on biodiversity is limited to a few taxa, often sampled in different locations with complex land-use histories, hampering attempts to plan cost-effective conservation strategies and to draw conclusions across taxa. Spanning a land-use gradient of primary forest, once- and twice-logged forests, and oil palm plantations, we used traditional sampling and DNA metabarcoding to compile an extensive data set in Sabah, Malaysian Borneo for nine vertebrate and invertebrate taxa to quantify the biological impacts of logging and oil palm, develop cost-effective methods of protecting biodiversity, and examine whether there is congruence in response among taxa. Logged forests retained high species richness, including, on average, 70% of species found in primary forest. In contrast, conversion to oil palm dramatically reduces species richness, with significantly fewer primary-forest species than found on logged forest transects for seven taxa. Using a systematic conservation planning analysis, we show that efficient protection of primary-forest species is achieved with land portfolios that include a large proportion of logged-forest plots. Protecting logged forests is thus a cost-effective method of protecting an ecologically and taxonomically diverse range of species, particularly when conservation budgets are limited. Six indicator groups (birds, leaf-litter ants, beetles, aerial hymenopterans, flies, and true bugs) proved to be consistently good predictors of the response of the other taxa to logging and oil palm. Our results confidently establish the high conservation value of logged forests and the low value of oil palm. Cross-taxon congruence in responses to disturbance also suggests that the practice of focusing on key indicator taxa yields important information of general biodiversity in studies of logging and oil palm.

Emergency clinicians must recognize the symptomatology of GAS pharyngitis and use appropriate means of diagnosis and treatment to promote good antibiotic stewardship. This issue reviews the signs and symptoms of GAS pharyngitis, as well as associated complications, and provides recommendations for appropriate treatment that focuses on reducing the severity and duration of symptoms, reducing the incidence of nonsuppurative complications, and reducing transmission. PMID- 29185671 TI - Managing dislocations of the hip, knee, and ankle in the emergency department AB - Dislocation of the major joints of the lower extremities--hip, knee, and ankle- can occur due to motor-vehicle crashes, falls, and sports injuries. Hip dislocations are the most common, and they require emergent management to prevent avascular necrosis of the femoral head. Knee dislocations are uncommon but potentially dangerous injuries that can result in amputation due to the potential for missed secondary injury, especially if they are reduced spontaneously. Isolated ankle dislocations are relatively rare, as most ankle dislocations involve an associated fracture. This review presents an algorithmic approach to management that ensures that pain relief, imaging, reduction, vascular monitoring, and emergent orthopedic consultation are carried out in a timely fashion. PMID- 29185673 TI - Sentinel lymph node mapping in endometrial cancer: a systematic review and meta analysis. AB - INTRODUCTION: Appropriate extent of lymphadenectomy in clinically, early stage endometrial cancer remains controversial but sentinel lymph node (SLN) mapping has emerged as an alternative staging strategy, until the advent of molecular prognostic markers. We sought to perform a systematic review of the literature to determine pooled estimates for SLN detection rate and diagnostic accuracy, while exploring impact of the SLN on adjuvant therapy and oncologic outcomes. EVIDENCE ACQUISITION: We performed a systematic search utilizing Medline, EMBASE, and Web of Science electronic databases for all studies published in the English language until October 31, 2017. Studies were included for review and potential aggregate analyses if they contained at least 30 endometrial cancer patients with undergoing SLN mapping and reported on detection rates (overall, bilateral or para-aortic) or diagnostic accuracy (sensitivity and negative predictive value [NPV]). Pooled estimates were calculated via meta-analyses utilizing a random effects model. Studies reporting on the impact of SLN on adjuvant therapy, as well as studies comparing SLN mapping to completion lymphadenectomy were qualitatively reviewed and analyzed as well. EVIDENCE SYNTHESIS: We identified 48 eligible studies, which included 5348 patients for review and inclusion in the meta-analysis for SLN detection or diagnostic accuracy. The pooled SLN detection rates were were 87% (95% CI: 84-89%, 44 studies) for overall detection, 61% (95% CI: 56-66%, 36 studies) for bilateral detection, and 6% (95% CI: 3-9%, 31 studies) for para-aortic detection. Indocyanine green use improved overall (94%, 95% CI: 92-96%, 19 studies) SLN detection rates compared to blue tracer (86%, 95% CI: 83-89%, 31 studies) or technetium-99 (86%, 95% CI: 83-89%, 25 studies). This trend was similarly seen in terms of bilateral detection rates (74% vs. 59% vs. 57%, respectively). There was no difference in para-aortic SLN detection rate between each tracer. The pooled estimates for diagnostic accuracy for 34 studies were 94% (95% CI: 91-96%) for sensitivity and 100% (95% CI: 99 - 100%) for NPV. Diagnostic accuracy of SLN mapping was not negatively affected in patients with high-grade endometrial histology. Patients with SLN mapping are more likely to receive adjuvant therapy and do not have inferior survival or recurrence outcomes compared to those undergoing completion lymphadenectomy. CONCLUSIONS: SLN mapping is a feasible and accurate alternative to stage patients with endometrial cancer. Utilizing indocyanine green results in the highest SLN detection rates. Future studies should prospectively examine the impact of SLN mapping on progression free and overall survival. PMID- 29185674 TI - Effectiveness of Extracorporeal Shock Wave Therapy and kinesio taping in calcific tendinopathy of the shoulder: a randomized controlled trial. AB - BACKGROUND: Extracorporeal Shock Wave Therapy (ESWT) is effective in the treatment of calcific tendinopathy of the rotator cuff, eliciting an analgesic/anti-inflammatory action and promoting tissue regeneration. Kinesio taping (KT), another recently-introduced rehabilitative tool, exerts an analgesic and biomechanical action on joints and muscles. ESWT and KT may have a synergic effect when used in combination, but the effectiveness of the association has not been established. AIM: The aim of this study was to test if the association of KT with ESWT is superior to ESWT alone in the treatment of rotator cuff calcific tendinopathy. DESIGN: Randomized controlled trial. SETTING: Rehabilitation Institute outpatients. POPULATION: Forty-two patients with rotator cuff calcific tendinopathy were randomly assigned to the experimental group (ESWT+KT, N.=21) or control (ESWT, N.=21). METHODS: In the experimental group, patients underwent three sessions (once a week for 3 weeks) of ESWT with KT applied at the end of each session. Controls underwent three sessions of ESWT only. All patients were assessed before treatment (T0) and at 1 (T1), 4 (T2) and 12 weeks (T3) after the end of treatment with the following outcome measures: a visual analogue scale (VAS), the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, Subjective Shoulder Rating Questionnaire (SSRQ), and Oxford Shoulder Score (OSS). RESULTS: Both groups showed significant improvement in all outcome measures, but the time course differed between the two groups. At T1 vs. T0, the improvement was significantly better in ESWT+KT than ESWT on VAS (P=0.007), DASH (P<0.0001) and SSRQ (P=0.0001). Successive improvements at T2 vs. T1 and T3 vs. T2 did not differ significantly between the groups. At the end of follow-up, ESWT+KT still showed significantly greater improvement than ESWT on VAS (P=0.02) and SSRQ (P=0.038). CONCLUSIONS: KT associated with ESWT seems to improve the recovery in rotator cuff calcific tendinopathy with a faster therapeutic response compared to ESWT only. CLINICAL REHABILITATION IMPACT: Our results suggest the effectiveness of using KT as adjuvant therapy to ESWT in rotator cuff calcific tendinopathy, through enhancing the short-term analgesic action and the medium- to long-term biological-regenerative effects. PMID- 29185675 TI - Muscle stretching exercises and resistance training in fibromyalgia: which is better? A three-arm randomized controlled trial. AB - BACKGROUND: Exercise therapy is an effective component of fibromyalgia (FM) treatment. However, it is important to know the effects and specificities of the different types of exercise: muscle stretching and resistance training. AIM: To verify and compare the effectiveness of muscle stretching exercise and resistance training for symptoms and quality of life in FM patients. DESIGN: Randomized controlled trial. SETTING: Physical therapy service, FM outpatient clinic. POPULATION: Forty-four women with FM (79 screened). METHODS: Patients were randomly allocated into a stretching group (N.=14), resistance group (N.=16), and control group (N.=14). Pain was assessed using the visual analog scale, pain threshold using a Fischer dolorimeter, FM symptoms using the Fibromyalgia Impact Questionnaire (FIQ), and quality of life using the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). The three intervention groups continued with usual medical treatment. In addition, the stretching and resistance groups performed two different exercise programs twice a week for 12 weeks. RESULTS: After treatment, the stretching group showed the highest SF-36 physical functioning score (P=0.01) and the lowest bodily pain score (P=0.01). The resistance group had the lowest FIQ depression score (P=0.02). The control group had the highest score for FIQ morning tiredness and stiffness, and the lowest score for SF-36 vitality. In clinical analyses, the stretching group had significant improvement in quality of life for all SF-36 domains, and the resistance group had significant improvement in FM symptoms and in quality of life for SF-36 domains of physical functioning, vitality, social function, emotional role, and mental health. CONCLUSIONS: Muscle stretching exercise was the most effective modality in improving quality of life, especially with regard to physical functioning and pain, and resistance training was the most effective modality in reducing depression. CLINICAL REHABILITATION IMPACT: The trial included a control group and two intervention groups, both of which received exercise programs created specifically for patients with FM. In clinical practice, we suggest including both modalities in an exercise therapy program for FM.

AB - INTRODUCTION: Cerebral palsy is a group of movement and posture development disorders. 90% of this population has gait impairment, often due to the presence of spasticity. A number of studies emphasize the importance of combined physical therapy with botulinum toxin A treatment. However, no consensus can be reached concerning the content of the physiotherapy program after treatment with botulinum toxin A. The purpose of the present study was to investigate, through a systematic review of the literature, the effects of physiotherapeutic intervention on gait after botulinum toxin application in children with cerebral palsy. EVIDENCE ACQUISITION: PubMed, Scielo, Cochrane Library, OTseeker, and PEDro databases were searched for randomized trial published between January 2000 and January 2017. EVIDENCE SYNTHESIS: Sixty-eight articles were identified, four of which met the eligibility criteria and were selected for the present systematic review. A table was created showing the main characteristics of the studies (groups, inclusion criteria, dosage, injection site, physiotherapeutic intervention, evaluation and outcomes). CONCLUSIONS: This study offers a view on the increase in the therapeutic effectiveness of botulinum toxin A on the lower limbs when used in conjunction with a physiotherapeutic intervention, with improvements in mobility, gait pattern, range of motion and spasticity, which are maintained after the end of the physical therapy protocol. The use of botulinum toxin A on the lower limbs when used in conjunction with a physiotherapeutic intervention, can improve muscle tone, allowing a combined treatment and intended to provide improvement of motor ability and functional skills, and potentially, delay the need for surgery.

AB - Glycolipids play a central role in a variety of important biological processes in all living organisms. PatA is a membrane acyltransferase involved in the biosynthesis of phosphatidyl-myo-inositol mannosides (PIMs), key structural elements, and virulence factors of Mycobacterium tuberculosis. PatA catalyzes the transfer of a palmitoyl moiety from palmitoyl-CoA to the 6-position of the mannose ring linked to the 2-position of inositol in PIM1/PIM2. We report here the crystal structure of PatA in the presence of 6-O-palmitoyl-alpha-d mannopyranoside, unraveling the acceptor binding mechanism. The acceptor mannose ring localizes in a cavity at the end of a surface-exposed long groove where the active site is located, whereas the palmitate moiety accommodates into a hydrophobic pocket deeply buried in the alpha/beta core of the protein. Both fatty acyl chains of the PIM2 acceptor are essential for the reaction to take place, highlighting their critical role in the generation of a competent active site. By the use of combined structural and quantum-mechanics/molecular-mechanics (QM/MM) metadynamics, we unravel the catalytic mechanism of PatA at the atomic electronic level. Our study provides a detailed structural rationale for a stepwise reaction, with the generation of a tetrahedral transition state for the rate-determining step. Finally, the crystal structure of PatA in the presence of beta-d-mannopyranose and palmitate suggests an inhibitory mechanism for the enzyme, providing exciting possibilities for inhibitor design and the discovery of chemotherapeutic agents against this major human pathogen. PMID- 29185695 TI - Nanosized Difunctional Photo Responsive Magnetic Imprinting Polymer for Electrochemically Monitored Light-Driven Paracetamol Extraction. AB - Herein, a novel photoresponsive magnetic electrochemical imprinting sensor for the selective extraction of paracetamol from biological samples was designed. In particular, nanosized photoresponsive molecular imprinted polymers were prepared on the surface of magnetic Fe3O4 nanoparticles through living radical polymerization of azobenzene. The introduction of a magnetic-controlled glassy carbon electrode makes the immobilization and removal of nanosized photoresponsive molecular imprinted polymers on the magnetic-controlled glassy carbon electrode surface facilely operational. With the photoresponsive property, the sensor undergoes reversible release and uptake of paracetamol upon alternative irradiation at 365 and 440 nm basing on a configurational change of azobenzene monomer in the photoresponsive molecular imprinted polymers receptor sites. Simultaneously, these processes are monitored by the photoresponsive changes of electrochemical signal from paracetamol. Two linear ranges from 0.001 to 0.7 mmol L-1 (R2 = 0.96) and 0.7 to 7 mmol L-1 (R2 = 0.95) for paracetamol determination were obtained with a quantification limit of 0.000 86 mmol L-1 and a detection limit of 0.000 43 mmol L-1. The recoveries of paracetamol in the urine as determined by photoresponsive molecular imprinted polymers extraction were varied between 87.5% and 93.3%. As a consequence, combining photocontrolled selective extraction, interfacial stability from magnetic adsorption, and specifically electrochemical response, the photoresponsive molecular imprinted polymers sensor shows significant advantages for simultaneous separation, enrichment, and detection of trace paracetamol in biological samples. PMID- 29185696 TI - Mode of Action and Heterologous Expression of the Natural Product Antibiotic Vancoresmycin. AB - Antibiotics that interfere with the bacterial cytoplasmic membrane have long-term potential for the treatment of infectious diseases as this mode of action is anticipated to result in low resistance frequency. Vancoresmycin is an understudied natural product antibiotic consisting of a terminal tetramic acid moiety fused to a linear, highly oxygenated, stereochemically complex polyketide chain. Vancoresmycin shows minimum inhibitory concentrations (MICs) from 0.125 to 2 MUg/mL against a range of clinically relevant, antibiotic-resistant Gram positive bacteria. Through a comprehensive mode-of-action study, utilizing Bacillus subtilis reporter strains, DiSC3(5) depolarization assays, and fluorescence microscopy, we have shown that vancoresmycin selectively targets the cytoplasmic membrane of Gram-positive bacteria via a non-pore-forming, concentration-dependent depolarization mechanism. Whole genome sequencing of the producing strain allowed identification of the 141 kbp gene cluster encoding for vancoresmycin biosynthesis and a preliminary model for its biosynthesis. The size and complex structure of vancoresmycin could confound attempts to generate synthetic analogues. To overcome this problem and facilitate future studies, we identified, cloned, and expressed the 141 kbp biosynthetic gene cluster in Streptomyces coelicolor M1152. Elucidation of the mode-of-action of vancoresmycin, together with the heterologous expression system, will greatly facilitate further studies of this and related molecules. PMID- 29185697 TI - Donor-Acceptor-Type S,N-Heteroacene-Based Hole-Transporting Materials for Efficient Perovskite Solar Cells. AB - Two new donor-acceptor (D-A)-substituted S,N-heteroacene-based molecules were developed and investigated as hole-transporting material (HTM) for perovskite solar cells (PSCs). Optical and electrochemical characterization brought out that the energy levels of both HTMs are suitable for their use in PSCs. Consequently, a power-conversion efficiency of 17.7% and 16.1% was achieved from PSCs involving the HTM-1 and HTM-2, respectively. The optoelectronic properties in terms of series resistance, conductivity, and charge carrier recombination were further examined to unfold the potential of these new HTMs. Time-resolved photoluminescence spectroscopy brought out that the hole injection from the valence band of perovskite into HTMs follows the trend, which is in accordance with the position of the highest occupied molecular orbital. Overall, our findings underline the potential of S,N-heteroacene co-oligomers as promising HTM candidates for PSCs. PMID- 29185698 TI - Suppressing Shuttle Effect Using Janus Cation Exchange Membrane for High Performance Lithium-Sulfur Battery Separator. AB - Suppressing the shuttle effect of polysulfide ions to obtain high durability and good electrochemical performance is of great concern in the field of lithium sulfur batteries. To address this issue, a Janus membrane consisting of an ultrathin dense layer and a robust microporous layer is fabricated using cation exchange resin. Different from the composite membranes made from polyolefin membranes, the multiple layers of the Janus membrane in this study are synchronously generated by one step, getting rid of the additional complex coating processes. Excellent overall performance is obtained by the cooperation of multiple factors. The excellent ionic selectivity of cation exchange resin renders a great suppression of the shuttle effect, endowing the lithium-sulfur battery with high Coulombic efficiency of 92.0-99.0% (LiNO3-free electrolyte). The ultrathin property of a dense layer renders a low ionic resistance, resulting in 60% higher discharge capacity over the entire C-rates (versus the control sample with Celgard 2400 membrane). The robust macroporous layer supports the ultrathin layer to achieve a free-standing property, ensuring the usability of the Janus membrane. PMID- 29185699 TI - Mesoporous Iron Oxide Synthesized Using Poly(styrene-b-acrylic acid-b-ethylene glycol) Block Copolymer Micelles as Templates for Colorimetric and Electrochemical Detection of Glucose. AB - Herein, we report the soft-templated preparation of mesoporous iron oxide using an asymmetric poly(styrene-b-acrylic acid-b-ethylene glycol) (PS-b-PAA-b-PEG) triblock copolymer. This polymer forms a micelle consisting of a PS core, a PAA shell, and a PEG corona in aqueous solutions, which can serve as a soft template. The mesoporous iron oxide obtained at an optimized calcination temperature of 400 degrees C exhibited an average pore diameter of 39 nm, with large specific surface area and pore volume of 86.9 m2 g-1 and 0.218 cm3 g-1, respectively. The as-prepared mesoporous iron oxide materials showed intrinsic peroxidase-like activities toward the catalytic oxidation of 3,3',5,5'-tertamethylbenzidine (TMB) in the presence of hydrogen peroxide (H2O2). This mimetic feature was further exploited to develop a simple colorimetric (naked-eye) and electrochemical assay for the detection of glucose. Both our colorimetric (naked-eye and UV-vis) and electrochemical assays estimated the glucose concentration to be in the linear range from 1.0 MUM to 100 MUM with a detection limit of 1.0 MUM. We envisage that our integrated detection platform for H2O2 and glucose will find a wide range of applications in developing various biosensors in the field of personalized medicine, food-safety detection, environmental-pollution control, and agro biotechnology.

PMID- 29185701 TI - Strategy for the Improvement of the Mechanical Properties of Cellulose Nanofiber Reinforced High-Density Polyethylene Nanocomposites Using Diblock Copolymer Dispersants. AB - Cellulose nanofibers (CNFs) hold great potential as sustainable reinforcement fillers with excellent mechanical, thermal, and chemical properties. However, in polyolefin nanocomposite materials, the rational control of dispersion and the improvement of interfacial strength remain challenging. Herein we propose the tuning of the interface between CNF and high-density polyethylene by the design of polymer dispersants on the basis of surface free energy and the glass transition temperature. The former is related to the wettability against the polymer matrix and is therefore critical to the dispersion of CNF whereas the latter is related to the interfacial strength between CNF and HDPE. As a result of this investigation, we discovered a suitable dispersant for CNFs, poly(dicyclopentenyloxyethyl methacrylate)-block-poly(2-hydroxyethyl methacrylate), which played a pivotal role in achieving both a uniform dispersion of CNF and greatly improved mechanical properties, including a 4-fold increase of the Young's modulus over that of neat HDPE with 10 wt % CNF loading. PMID- 29185702 TI - Tailoring Fluorescence Brightness and Switching of Nanoparticles through Dye Organization in the Polymer Matrix. AB - Fluorescent nanoparticles (NPs) help to increase spatial and temporal resolution in bioimaging. Advanced microscopy techniques require very bright NPs that exhibit either stable emission for single-particle tracking or complete on/off switching (blinking) for super-resolution imaging. Here, ultrabright dye-loaded polymer NPs with controlled switching properties are developed. To this aim, the salt of a dye (rhodamine B octadecyl ester) with a hydrophobic counterion (fluorinated tetraphenylborate) is encapsulated at very high concentrations up to 30 wt % in NPs made of poly(lactic-co-glycolic acid) (PLGA), poly(methyl methacrylate) (PMMA), and polycaprolactone (PCL) through nanoprecipitation. The obtained 35 nm NPs are nearly 100 times brighter than quantum dots. The nature of the polymer is found to define the collective behavior of the encapsulated dyes so that NPs containing thousands of dyes exhibit either whole particle blinking, for PLGA, or stable emission, for PMMA and PCL. Fluorescence anisotropy measurements together with small-angle X-ray scattering experiments suggest that in less hydrophobic PLGA, dyes tend to cluster, whereas in more hydrophobic PMMA and PCL, dyes are dispersed within the matrix, thus altering the switching behavior of NPs. Experiments using a perylene diimide derivative show a similar effect of the polymer nature. The resulting fluorescent NPs are suitable for a wide range of imaging applications from tracking to super-resolution imaging. The findings on the organization of the load innside NPs will have impact on the development of materials for applications ranging from photovoltaics to drug delivery. PMID- 29185703 TI - Homospermidine Lipids: A Compound Class Specifically Formed during Fruiting Body Formation of Myxococcus xanthus DK1622. AB - The fascinating ability of myxobacteria to form multicellular spore filled fruiting bodies under starvation conditions was widely studied as a model for cooperative microbial behavior. The potential of a life cycle induced change of secondary metabolism, as a means to discover novel natural products, remains largely underexplored. We therefore studied the model organism Myxococcus xanthus DK1622 under submersed and solid cultivation conditions to find putatively life cycle related compounds by applying statistical analysis on analytical data. Utilizing the advantageous characteristics of LC-MS, LC-MS/MS, and MALDI-MSI allowed the identification of compounds unambiguously associated with myxobacterial fruiting bodies. Our screening effort resulted in the purification and structure elucidation of a novel compound, the homospermidine lipid, from cultures that had undergone the fruiting process. A combination of molecular networking and targeted LC-MS/MS in conjunction with our in-house metabolomics database subsequently revealed alternative producers of the respective compound as well as a number of compounds belonging to the same structural class. Three further members of this compound class were isolated from an alternative producer and structurally elucidated by NMR. Insights into the biosynthesis of this novel compound class was gained by feeding of isotopically labeled substrates and in silico analysis. PMID- 29185704 TI - Functional Design of Highly Robust and Flexible Thin-Film Encapsulation Composed of Quasi-Perfect Sublayers for Transparent, Flexible Displays. AB - In this study, a structurally and materially designed thin-film encapsulation is proposed to guarantee the reliability of transparent, flexible displays by significantly improving their barrier properties, mechanical stability, and environmental reliability, all of which are essential for organic light-emitting diode (OLED) encapsulation. We fabricated a bioinspired, nacre-like ZnO/Al2O3/MgO laminate structure (ZAM) using atomic layer deposition for the microcrack toughening effect. The ZAM film was formed with intentional voids and defects through the formation of a quasi-perfect sublayer, rather than the simple fabrication of nanolaminate structures. The 240 nm thick ZAM-based multibarrier (ZAM-TFE) with a compressively strained organic layer demonstrated an optical transmittance of 91.35% in the visible range, an extremely low water vapor transmission rate of 2.06 * 10-6 g/m2/day, a mechanical stability enduring a strain close to 1%, and a residual stress close to 0, showing significant improvement of key TFE properties in comparison to an Al2O3-based multibarrier. In addition, ZAM-TFE demonstrated superior environmental resistance without degradation of barrier properties in a severe environment of 85 degrees C and 90% relative humidity (RH). Thus, our structurally and materially designed ZAM film has been well optimized in terms of its applicability as a gas diffusion barrier as well as in terms of its mechanical and environmental reliability. Finally, we confirmed the feasibility of the ZAM-TFE through application in OLEDs. The low-temperature ZAM-TFE technology showed great potential to provide a highly robust and flexible TFE of TFOLEDs. PMID- 29185705 TI - Ultrathin Polydiacetylene-Based Synergetic Composites with Plasmon-Enhanced Photoelectric Properties. AB - Fabricating plasmon-enhanced organic nanomaterials with technologically relevant supporting architectures on planar solids remains a challenging task in the chemistry of thin films and interfaces. In this work, we report a bottom-up assembly of ultrathin layered composites of conductive polymers with photophysical properties enhanced by gold nanoparticles. The polydiacetylene component was formed by photopolymerization of a catanionic mixture of pentacosadiynoic surfactants on a surface of citrate-stabilized gold hydrosol monitored by a fiber optic spectrometer. Microscopic examination of the 3 nm thick solid-immobilized film showed that gold nanoparticles (AuNPs) do not aggregate within the monolayer upon polymerization. This polydiacetylene/AuNPs monolayer was coupled with 60 nm thick polyaniline-based layer deposited atop. The resulting polymer composite with an integrated 4-stripe electric cell showed nonadditive electric behavior due to the formation of electron-hole pairs with increased charge carrier mobility at the interface between the polymer layers. Under visible light irradiation of the composite film, a plasmonic effect of the gold nanoparticles was observed at the onset of photoconductivity, although neither polydiacetylene nor the polyaniline component alone are photoconductive polymers. The results indicate that our bottom-up strategy can be expanded to design other plasmon-enhanced ultrathin polymer composites with potential applications in optoelectronics and photovoltaics.

AB - Graphene-based wearable e-textiles are considered to be promising due to their advantages over traditional metal-based technology. However, the manufacturing process is complex and currently not suitable for industrial scale application. Here we report a simple, scalable, and cost-effective method of producing graphene-based wearable e-textiles through the chemical reduction of graphene oxide (GO) to make stable reduced graphene oxide (rGO) dispersion which can then be applied to the textile fabric using a simple pad-dry technique. This application method allows the potential manufacture of conductive graphene e textiles at commercial production rates of ~150 m/min. The graphene e-textile materials produced are durable and washable with acceptable softness/hand feel. The rGO coating enhanced the tensile strength of cotton fabric and also the flexibility due to the increase in strain% at maximum load. We demonstrate the potential application of these graphene e-textiles for wearable electronics with activity monitoring sensor. This could potentially lead to a multifunctional single graphene e-textile garment that can act both as sensors and flexible heating elements powered by the energy stored in graphene textile supercapacitors. PMID- 29185707 TI - Atomic-Scale Choreography of Vapor-Liquid-Solid Nanowire Growth. AB - Functional materials and devices require nanoscale control of morphology, crystal structure, and composition. Vapor-liquid-solid (VLS) crystal growth and its related growth modes enable the synthesis of 1D nanostructures, commonly called "nanowires", where the necessary nanoscale heterogeneity can be encoded axially. During the VLS process, a seed particle collects atoms and directs the nucleation of crystalline material. Modulating the delivery of growth species or conditions permits compositional and/or structural encoding. A range of materials and devices (e.g., for electronics, photonics, thermal transport, and bioprobes) have been produced by VLS growth, but plenty of challenges remain: many desirable structures cannot currently be made, and even for those structures that can be made, the parameter window-in terms of, e.g., temperatures and pressures-is often narrow. Moreover, we are quite far from ab initio determination of which growth conditions should be used or even if a desired structure is fundamentally achievable within the VLS framework. To fully understand the challenges and promises of VLS growth, the governing physicochemical processes must be explored and understood at the atomic scale. This final level of detail is being unraveled with the help of in situ characterization techniques. The picture that is emerging is of a highly dynamical process with several deeply interconnected and highly fundamental components that are difficult to detect with postgrowth ex situ interrogation. For example, recent in situ microscopy and spectroscopy studies have shown that the growth front can undergo cyclical reshaping involving dissolution as well as crystallization and that the state of the nanowire surface, which changes with growth conditions as a result of a competition between adsorption and desorption of passivating species, plays a crucial role in determining the transport to/from and the stability of the seed particle. The available in situ observations currently constitute a somewhat disparate list, but if they can be connected to each other and to the outstanding challenges, they promise meaningful advances in our understanding of VLS growth. In this Account, we review the state of the art regarding the atomic-scale thermodynamic and kinetic phenomena that control VLS growth. Rather than cataloging all of the outstanding contributions to the field, we give priority to in situ observations that have revealed unexpected effects as well as those that hint at incongruities in our current knowledge. As such, our discussion should be viewed as an opportunity to gain deeper understanding and control of the fundamental processes at play, which will be crucial in future scale-up efforts and expansion to completely new materials systems and application areas.

AB - Rett syndrome (RTT) is a unique neurodevelopmental disorder that primarily affects females resulting in severe cognitive and physical disabilities. Despite the commendable collective efforts of the research community to better understand the genetics and underlying biology of RTT, there is still no cure. However, in the past 50 years, since the first report of RTT, steady progress has been made in the accumulation of clinical and molecular information resulting in the identification of a number of genes associated with RTT and associated phenotypes, improved diagnostic criteria, natural history studies, curation of a number of databases capturing genotypic and phenotypic data, a number of promising clinical trials and exciting novel therapeutic options which are currently being tested in laboratory and clinical settings. This Review focuses on the current knowledge of the clinical aspects of RTT, with particular attention being paid to clinical trials and the comorbidities of the disorder as well as the genetic etiology and the recognition of new diseases genes. PMID- 29185708 TI - The Autophagy-Related Beclin-1 Protein Requires the Coiled-Coil and BARA Domains To Form a Homodimer with Submicromolar Affinity. AB - Beclin-1 (BECN1) is an essential component of macroautophagy. This process is a highly conserved survival mechanism that recycles damaged cellular components or pathogens by encasing them in a bilayer vesicle that fuses with a lysosome to allow degradation of the vesicular contents. Mutations or altered expression profiles of BECN1 have been linked to various cancers and neurodegenerative diseases. Viruses, including HIV and herpes simplex virus 1 (HSV-1), are also known to specifically target BECN1 as a means of evading host defense mechanisms. Autophagy is regulated by the interaction between BECN1 and Bcl-2, a pro-survival protein in the apoptotic pathway that stabilizes the BECN1 homodimer. Disruption of the homodimer by phosphorylation or competitive binding promotes autophagy through an unknown mechanism. We report here the first recombinant synthesis (3-5 mg/L in an Escherichia coli culture) and characterization of full-length, human BECN1. Our analysis reveals that full-length BECN1 exists as a soluble homodimer (KD ~ 0.45 MUM) that interacts with Bcl-2 (KD = 4.3 +/- 1.2 MUM) and binds to lipid membranes. Dimerization is proposed to be mediated by a coiled-coil region of BECN1. A construct lacking the C-terminal BARA domain but including the coiled coil region exhibits a homodimer KD 3.5-fold weaker than that of full-length BECN1, indicating that both the BARA domain and the coiled-coil region of BECN1 contribute to dimer formation. Using site-directed mutagenesis, we show that residues at the C-terminus of the coiled-coil region previously shown to interact with the BARA domain play a key role in dimerization and mutations weaken the interface by ~5-fold. PMID- 29185710 TI - Quantum Dots of 1T Phase Transitional Metal Dichalcogenides Generated via Electrochemical Li Intercalation. AB - We prepare group VI transitional metal dichalcogenides (TMDs, or MX2) from the 1T phase with quantum-sized and monolayer features via a quasi-full electrochemical process. The resulting two-dimensional (2D) MX2 (M = W, Mo; X = S, Se) quantum dots (QDs) are ca. 3.0-5.4 nm in size with a high 1T phase fraction of ca. 92% 97%. We attribute this to the high Li content intercalated in the 1T-MX2 lattice (mole ratio of Li:M is over 2:1), which is achieved by an increased lithiation driving force and a reduced electrochemical lithiation rate (0.001 A/g). The high Li content not only promotes the 2H -> 1T phase transition but also generates significant inner stress that facilitates lattice breaking for MX2 crystals. Because of their high proportion of metallic 1T phase and sufficient active sites induced by the small lateral size, the 2D 1T-MoS2 QDs show excellent hydrogen evolution reactivity (with a typical eta10 of 92 mV, Tafel slope of 44 mV/dec, and J0 of 4.16 * 10-4 A/cm2). This electrochemical route toward 2D QDs might help boost the development of 2D materials in energy-related areas.

AB - Rhomboids are intramembrane serine proteases and belong to the group of structurally and biochemically most comprehensively characterized membrane proteins. They are highly conserved and ubiquitously distributed in all kingdoms of life and function in a wide range of biological processes, including epidermal growth factor signaling, mitochondrial dynamics, and apoptosis. Importantly, rhomboids have been associated with multiple diseases, including Parkinson's disease, type 2 diabetes, and malaria. However, despite a thorough understanding of many structural and functional aspects of rhomboids, potent and selective inhibitors of these intramembrane proteases are still not available. In this study, we describe the computer-based rational design, chemical synthesis, and biological evaluation of novel N-methylene saccharin-based rhomboid protease inhibitors. Saccharin inhibitors displayed inhibitory potency in the submicromolar range, effectiveness against rhomboids both in vitro and in live Escherichia coli cells, and substantially improved selectivity against human serine hydrolases compared to those of previously known rhomboid inhibitors. Consequently, N-methylene saccharins are promising new templates for the development of rhomboid inhibitors, providing novel tools for probing rhomboid functions in physiology and disease.

PMID- 29185715 TI - Quantitative Framework for Stochastic Nanopore Sensors Using Multiple Channels. AB - Membrane protein channels employed as stochastic sensors offer large signal-to noise ratios and high specificity in single molecule binding measurements. Stochastic events in a single ion channel system can be measured using current time traces, which are straightforward to analyze. Signals arising from measurement using multiple ion channels are more complicated to interpret. We show that multiple independent ion channels offer improved detection sensitivity compared to single channel measurements and that increased signal complexity can be accounted for using binding event frequency. More specifically, the leading edge of binding events follows a Poisson point process, which means signals from multiple channels can be superimposed and the association times (between each binding event leading edge), allow for sensitive and quantitative measurements. We expand our calibration to high ligand concentrations and high numbers of ion channels to demonstrate that there is an upper limit of quantification, defined by the time resolution of the measurement. The upper limit is a combination of the instrumental time resolution and the dissociation time of a ligand and protein which limits the number of detectable events. This upper limit also allows us to predict, in general, the measurement requirements needed to observe any process as a Poisson point process. The nanopore-based sensing analysis has wide implications for stochastic sensing platforms that operate using multiple simultaneous superimposable signals. PMID- 29185716 TI - Pollutants in Plastics within the North Pacific Subtropical Gyre. AB - Here we report concentrations of pollutants in floating plastics from the North Pacific accumulation zone (NPAC). We compared chemical concentrations in plastics of different types and sizes, assessed ocean plastic potential risks using sediment quality criteria, and discussed the implications of our findings for bioaccumulation. Our results suggest that at least a fraction of the NPAC plastics is not in equilibrium with the surrounding seawater. For instance, "hard plastic" samples had significantly higher PBDE concentrations than "nets and ropes" samples, and 29% of them had PBDE composition similar to a widely used flame-retardant mixture. Our findings indicate that NPAC plastics may pose a chemical risk to organisms as 84% of the samples had at least one chemical exceeding sediment threshold effect levels. Furthermore, our surface trawls collected more plastic than biomass (180 times on average), indicating that some NPAC organisms feeding upon floating particles may have plastic as a major component of their diets. If gradients for pollutant transfer from NPAC plastic to predators exist (as indicated by our fugacity ratio calculations), plastics may play a role in transferring chemicals to certain marine organisms.

PMID- 29185717 TI - High Pressure Size Exclusion Chromatography (HPSEC) Determination of Dissolved Organic Matter Molecular Weight Revisited: Accounting for Changes in Stationary Phases, Analytical Standards, and Isolation Methods. AB - We reassessed the molecular weight of dissolved organic matter (DOM) determined by high pressure size exclusion chromatography (HPSEC) using measurements made with different columns and various generations of polystyrenesulfonate (PSS) molecular weight standards. Molecular weight measurements made with a newer generation HPSEC column and PSS standards from more recent lots are roughly 200 to 400 Da lower than initial measurements made in the early 1990s. These updated numbers match DOM molecular weights measured by colligative methods and fall within a range of values calculated from hydroxyl radical kinetics. These changes suggest improved accuracy of HPSEC molecular weight measurements that we attribute to improved accuracy of PSS standards and changes in the column packing. We also isolated DOM from wetlands in the Prairie Pothole Region (PPR) using XAD-8, a cation exchange resin, and PPL, a styrene-divinylbenzene media, and observed little difference in molecular weight and specific UV absorbance at 280 nm (SUVA280) between the two solid phase extraction resins, suggesting they capture similar DOM moieties. PPR DOM also showed lower SUVA280 at similar weights compared to DOM isolates from a global range of environments, which we attribute to oxidized sulfur in PPR DOM that would increase molecular weight without affecting SUVA280. PMID- 29185719 TI - A Novel Domain Assembly Routine for Creating Full-Length Models of Membrane Proteins from Known Domain Structures. AB - Membrane proteins composed of soluble and membrane domains are often studied one domain at a time. However, to understand the biological function of entire protein systems and their interactions with each other and drugs, knowledge of full-length structures or models is required. Although few computational methods exist that could potentially be used to model full-length constructs of membrane proteins, none of these methods are perfectly suited for the problem at hand. Existing methods require an interface or knowledge of the relative orientations of the domains or are not designed for domain assembly, and none of them are developed for membrane proteins. Here we describe the first domain assembly protocol specifically designed for membrane proteins that assembles intra- and extracellular soluble domains and the transmembrane domain into models of the full-length membrane protein. Our protocol does not require an interface between the domains and samples possible domain orientations based on backbone dihedrals in the flexible linker regions, created via fragment insertion, while keeping the transmembrane domain fixed in the membrane. For five examples tested, our method mp_domain_assembly, implemented in RosettaMP, samples domain orientations close to the known structure and is best used in conjunction with experimental data to reduce the conformational search space.

AB - Single crystals of BiFe0.9Co0.1O3 and BiFe0.892Mn0.008Co0.1O3, room temperature ferroelectric ferromagnets, were successfully grown by a flux method at a high pressure of 3 GPa. Remanent magnetization measurements along 18 crystallographic directions revealed the existence of a magnetic easy plane perpendicular to the electric polarization. Reorientation of the magnetic easy plane occurred in connection with 71 degrees ferroelectric switching by applying an electric field. This is the first demonstration of an electric field affecting the local magnetic moment of Co-substituted BiFeO3. PMID- 29185721 TI - Deviations from the Most Spherical Deltahedra in Rhenatricarbaboranes Having 2n + 2 Wadean Skeletal Electrons. AB - Density functional theory studies on the rhenatricarbaboranes C3Bn-4Hn-1Re(CO)3 (n = 7-12) show that the lowest energy polyhedra for n-vertex metallaboranes having 2n + 2 skeletal electrons and sufficiently dissimilar vertex atoms can deviate from the most spherical closo deltahedra predicted by application of the Wade-Mingos rules. Furthermore, the lowest energy structures of these rhenatricarbaboranes are found to avoid C-C edges and have carbon atoms located at degree 4 rather than degree 5 vertices. The lowest energy structures for the 7 vertex C3B3H6Re(CO)3 system all have a central C3B3Re closo deltahedron, namely the pentagonal bipyramid with the rhenium atom at a degree 5 axial vertex and all three carbon atoms at degree 4 equatorial vertices. However, the lowest energy structure for the 8-vertex C3B4H7Re(CO)3 is not the most spherical closo 8-vertex deltahedron, namely the bisdisphenoid, but instead a central C3B4Re hexagonal bipyramid with mutually nonadjacent degree 4 vertices for the carbon atoms. Similarly, the lowest energy 10-vertex C3B6H9Re(CO)3 structures are derived from isocloso deltahedra having three degree 4 vertices for all three carbon atoms rather than from the most spherical 10-vertex closo deltahedron, namely the bicapped square antiprism with only two degree 4 vertices. However, for the 9 vertex C3B5H8Re(CO)3 system, the most spherical closo deltahedron, namely the tricapped trigonal prism, has three mutually nonadjacent degree 4 vertices, which is ideal for the three carbon atoms and thus is the preferred deltahedron. The preferred deltahedron for the 11-vertex C3B7H10Re(CO)3 remains the most spherical closo deltahedron despite having only two degree 4 vertices for the carbon atoms. Furthermore, the six lowest energy 12-vertex C3B8H11Re(CO)3 structures are all based on the regular icosahedron generally favored in polyhedral borane chemistry despite its complete lack of degree 4 vertices for the carbon atoms.

AB - Iminopyridine modified by TEMPO nitroxide was utilized for the synthesis of an octahedral bis(o-semiquinonato)cobalt complex. Variable-temperature magnetic susceptibility measurements detect a valence tautomeric transformation in the temperature range 200-300 K. A reproducible hysteresis loop of about 40 K width is observed on the magnetic moment temperature dependence in the transition region. Differential scanning calorimetry measurements confirm different temperatures of phase transitions accompanying a valence-tautomeric transformation upon heating and cooling. Attempts to study the structural changes associated with the valence-tautomeric transformation by single-crystal X-ray diffraction failed because of the crystal destruction taking place upon cooling from 220 K. The powder X-ray diffraction pattern indicated an essential change of the unit cell upon cooling from 240 K. PMID- 29185723 TI - Phase Transitions of Thermoelectric TAGS-85. AB - The alloys (GeTe)x(AgSbTe2)100-x, commonly known as TAGS-x, are among the best performing p-type thermoelectric materials for the composition range 80 <= x <= 90 and in the temperature range 200-500 degrees C. They adopt a rhombohedrally distorted rocksalt structure at room temperature and are reported to undergo a reversible phase transition to a cubic structure at ~250 degrees C. However, we show that, for the optimal x = 85 composition (TAGS-85), both the structural and thermoelectric properties are highly sensitive to the initial synthesis method employed. Single-phase rhombohedral samples exhibit the best thermoelectric properties but can only be obtained after an annealing step at 600 degrees C during initial cooling from the melt. Under faster cooling conditions, the samples obtained are inhomogeneous, containing multiple rhombohedral phases with a range of lattice parameters and exhibiting inferior thermoelectric properties. We also find that when the room-temperature rhombohedral phase is heated, an intermediate trigonal structure containing ordered cation vacancy layers is formed at ~200 degrees C, driven by the spontaneous precipitation of argyrodite type Ag8GeTe6 which alters the stoichiometry of the TAGS-85 matrix. The rhombohedral and trigonal phases of TAGS-85 coexist up to 380 degrees C, above which a single cubic phase is obtained and the Ag8GeTe6 precipitates redissolve into the matrix. On subsequent cooling a mixture of rhombohedral, trigonal, and Ag8GeTe6 phases is again obtained. Initially single-phase samples exhibit thermoelectric power factors of up to 0.0035 W m-1 K-2 at 500 degrees C, a value that is maintained on subsequent thermal cycling and which represents the highest power factor yet reported for undoped TAGS-85. Therefore, control over the structural homogeneity of TAGS-85 as demonstrated here is essential in order to optimize the thermoelectric performance.

AB - Parabens, phthalates, and perfluorinated compounds are pollutant compounds used in cosmetics, plastics, and fire-fighting foams. All three compounds have been studied over several years for toxicity mechanism; however, a clear view of their ability to bind to DNA has not been supplied empirically. In this work, a simulation study is done to reveal the interaction of three of these pollutants, bis(2-ethylhexyl)-phthalate (DEHP), butylparaben (BPRB), and the protonated form of perfluorooctanesulfonic acid (PFOS(H)), with DNA. The results show that the DEHP, PFOS(H), and BPRB bind with a probability of 1/5 to DNA, with respective bonding energies -23.96 kJ/mol (PFOS(H)), -94.92 kJ/mol (BPRB), and -216.52 kJ/mol (DEHP). The positive control, benzo[a]pyrene diol epoxide (BAP), which is known for its notorious DNA intercalation, binds at a rate of 3/5 simulations, with bonding energies of -6544.52, -7034.66, and -7578.67 kJ/mol. The results are compared to empirical studies and conclusively show that all these pollutants can interfere with transcription and DNA related mechanisms by forming noncovalent interactions with DNA. The results show also that these pollutants are unlikely to undergo strong noncovalent intercalation to DNA, such as BAP, and do not possess the frontier orbital profiles to undergo adduct formation. After many years of research and several unanswered questions on the action of these pollutants on DNA, a calculation on their properties hence to the DNA confirms that there is a low probability for these to undergo a strong intercalation with DNA. Literature shows however that the pollutants are strongly interfering with the protein machinery and receptors on the cell surface and are therefore still priority pollutants for ecotoxicity research.

AB - Two novel heterobimetallic complexes, a trigonal-bipyramidal and a cubic one, have been synthesized and characterized using the same C3-symmetric metalloligand, prepared by a simple subcomponent self-assembly strategy. Adopting the molecular library approach, we chose a mononuclear, preorganized iron(II) complex as the metalloligand capable of self-assembly into a trigonal-bipyramidal or a cubic aggregate upon coordination to cis-protected C2-symmetric palladium(II) or unprotected tetravalent palladium(II) ions, respectively. The trigonal-bipyramidal complex was characterized by NMR and UV-vis spectroscopy, electrospray ionization mass spectrometry (ESI-MS), and single-crystal X-ray diffraction. The cubic structure was characterized by NMR and UV-vis spectroscopy and ESI-MS.

AB - The [2,3]-sigmatropic rearrangement of allylic sulfoxides to allylic sulfenates is a reversible process, generally shifted toward the sulfoxide. In the presence of thiophiles, the sulfenate is trapped, and allylic alcohols are obtained under mild conditions. In most cases, a good transfer of stereochemical information through an ordered transition state is obtained. Furthermore, the ease of coupling this process with other versatile, stereocontrolled reactions has enhanced the usefulness of this protocol. This review aims to provide a comprehensive survey of this rearrangement and its application in the synthesis of natural and bioactive products. PMID- 29185727 TI - Hyperfine Effects in Ligand NMR: Paramagnetic Ru(III) Complexes with 3 Substituted Pyridines. AB - NMR spectroscopy is an indispensable tool in characterizing molecular systems, including transition-metal complexes. However, paramagnetic transition-metal complexes such as those with ruthenium in the +3 oxidation state are troublemakers because their unpaired electrons induce a fast nuclear spin relaxation that significantly broadens their NMR resonances. We recently demonstrated that the electronic and spin structures of paramagnetic Ru(III) systems can be characterized in unprecedented details by combining experimental NMR results with relativistic density-functional theory ( Novotny et al. J. Am. Chem. Soc. 2016 , 138 , 8432 ). In this study we focus on paramagnetic analogs of NAMI with the general structure [3-R-pyH]+trans-[RuIIICl4(DMSO)(3-R-py)]-, where 3-R-py stands for a 3-substituted pyridine. The experimental NMR data are interpreted in terms of the contributions of hyperfine (HF) NMR shielding and the distribution of spin density calculated using relativistic DFT. The DFT computational methodology is evaluated, and the effects of substituents, environment, and relativity on the hyperfine shielding are discussed. Particular attention is paid to the analysis of the fundamental Fermi-contact (FC), spin dipole (SD), and paramagnetic spin-orbit (PSO) terms that contribute to the hyperfine 1H and 13C NMR shifts of the individual atoms in the pyridine ligands and the spin-polarization effects in the ligand system that are linked to the character of the metal-ligand bond. The individual HF shielding terms are systematically discussed as they relate to the traditional, but somewhat mixed, contact and pseudocontact NMR contributions used extensively by experimental spectroscopists in biomolecular NMR and the development of PARACEST magnetic resonance contrast agents. PMID- 29185728 TI - Two-Dimensional Lead Halide Perovskites Templated by a Conjugated Asymmetric Diammonium. AB - We report novel two-dimensional lead halide perovskite structures templated by a unique conjugated aromatic dication, N,N-dimethylphenylene-p-diammonium (DPDA). The asymmetrically substituted primary and tertiary ammoniums in DPDA facilitate the formation of two-dimensional network (2DN) perovskite structures incorporating a conjugated dication between the PbX42- (X = Br, I) layers. These 2DN structures of (DPDA)PbI4 and (DPDA)PbBr4 were characterized by single-crystal X-ray diffraction, showing uniquely low distortions in the Pb-X-Pb bond angle for 2D perovskites. The Pb-I-Pb bond angle is very close to ideal (180 degrees ) for a 2DN lead iodide perovskite, which can be attributed to the ability of the rigid diammonium DPDA to insert into the PbX62- octahedral pockets. Optical characterization of (DPDA)PbI4 shows an excitonic absorption peak at 2.29 eV (541 nm), which is red-shifted in comparison to similar 2DN lead iodide structures. Temperature-dependent photoluminescence of both compounds reveals both a self trapped exciton and free exciton emission feature. The reduced exciton absorption energy and emission properties are attributed to the dication-induced structural order of the inorganic PbX42- layers. DFT calculation results suggest mixing of the conjugated organic orbital component in the valence band of these 2DN perovskites. These results demonstrate a rational new strategy to incorporate conjugated organic dications into hybrid perovskites and will spur spectroscopic investigations of these compounds as well as optoelectronic applications.

AB - The synthesis, composition, and catalytic properties of a new family of hexanuclear Cu(II)-based phenylsilsesquioxanes are described here. Structural studies of 17 synthesized compounds revealed the general principle underlying their molecular topology: viz., a central metal oxide layer consisting of two Cu3 trimers is coordinated by two cyclic [PhSiO1.5]5 siloxanolate ligands to form a skewed sandwich architecture with the composition [(PhSiO1.5)10(CuO)6]2+. In addition to this O ligation by the siloxanolate rings, two opposite copper ions are additionally coordinated by the nitrogen atoms of corresponding N ligand(s), such as 2,2'-bipyridine (compounds 1-9), 1,10-phenanthroline (compounds 10-13), mixed 1,10-phenanthroline/2,2'-bipyridine (compound 14), or bathophenanthroline (compounds 15-17). Finally, the charge balance is maintained by two HO- (compounds 1-7, 10-13, and 15-17), two H3CO- (compound 8), or two CH3COO- (compounds 9 and 14) anions. Complexes 1 and 10 exhibited a high activity in the oxidative amidation oxidation of alcohols. Compounds 1, 10, and 15 are very efficient homogeneous catalysts in the oxidation of alkanes and alcohols with peroxides. PMID- 29185730 TI - Understanding Poly(vinyl alcohol)-Mediated Ice Recrystallization Inhibition through Ice Adsorption Measurement and pH Effects. AB - The development of improved cryopreservative materials is necessary to enable complete recovery of living cells and tissue after frozen storage. Remarkably, poly(vinyl alcohol) (PVA) displays some of the same cryoprotective properties as many antifreeze proteins found in cold tolerant organisms. In particular, PVA is very effective at halting the Ostwald ripening of ice, a process that mechanically damages cells and tissue. Despite the large practical importance of such a property, the mechanism by which PVA interacts with ice is poorly understood, hindering the development of improved cryoprotective materials. Herein, we quantitatively evaluated ice growth kinetics in the presence of PVA at different pH conditions and in the presence of a range of neutral salts. We demonstrated that pH, but not salt identity, alters the ability of PVA to halt ice grain coarsening. These observations are consistent with hydrogen-bonding playing a crucial role in PVA-mediated ice recrystallization inhibition. The evolution of the size distribution of ice crystals with annealing was consistent with incomplete surface coverage of ice with PVA. Binding assay measurements of dissolved fluorescently labeled PVA in an ice slurry showed that PVA interacts with ice through weak adsorption (<9%) to the ice crystal surface, which stands in contrast to fluorescently tagged type III antifreeze peptide, which binds strongly (ca. 64%) under the same conditions. PMID- 29185731 TI - Silicone Wristband Passive Samplers Yield Highly Individualized Pesticide Residue Exposure Profiles. AB - Monitoring human exposure to pesticides and pesticide residues (PRs) remains crucial for informing public health policies, despite strict regulation of plant protection product and biocide use. We used 72 low-cost silicone wristbands as noninvasive passive samplers to assess cumulative 5-day exposure of 30 individuals to polar PRs. Ethyl acetate extraction and LC-MS/MS analysis were used for the identification of PRs. Thirty-one PRs were detected of which 15 PRs (48%) were detected only in worn wristbands, not in environmental controls. The PRs included 16 fungicides (52%), 8 insecticides (26%), 2 herbicides (6%), 3 pesticide derivatives (10%), 1 insect repellent (3%), and 1 pesticide synergist (3%). Five detected pesticides were not approved for plant protection use in the EU. Smoking and dietary habits that favor vegetable consumption were associated with higher numbers and higher cumulative concentrations of PRs in wristbands. Wristbands featured unique PR combinations. Our results suggest both environment and diet contributed to PR exposure in our study group. Silicone wristbands could serve as sensitive passive samplers to screen population-wide cumulative dietary and environmental exposure to authorized, unauthorized and banned pesticides. PMID- 29185732 TI - Efficient Energy Transfer from Near-Infrared Emitting Gold Nanoparticles to Pendant Ytterbium(III). AB - Here, we demonstrate efficient energy transfer from near-infrared-emitting ortho mercaptobenzoic acid-capped gold nanoparticles (AuNPs) to pendant ytterbium(III) cations. These functional materials combine the high molar absorptivity (1.21 * 106 M-1 cm-1) and broad excitation features (throughout the UV and visible regions) of AuNPs with the narrow emissive properties of lanthanides. Interaction between the AuNP ligand shell and ytterbium is determined using both nuclear magnetic resonance and electron microscopy measurements. In order to identify the mechanism of this energy transfer process, the distance of the ytterbium(III) from the surface of the AuNPs is systematically modulated by changing the size of the ligand appended to the AuNP. By studying the energy transfer efficiency from the various AuNP conjugates to pendant ytterbium(III) cations, a Dexter-type energy transfer mechanism is suggested, which is an important consideration for applications ranging from catalysis to energy harvesting. Taken together, these experiments lay a foundation for the incorporation of emissive AuNPs in energy transfer systems.

The key steps involve the highly cis-selective bis-addition of 4 bromo-4'-lithiobiphenyl to the quinones to produce a five-ring unit containing cyclohexa-1,4-diene-3,6-diol moiety, the platinum-mediated dimerization of the five-ring unit, and the H2SnCl4-mediated reductive aromatization of cyclohexadienediol. The tetraalkoxy substituents increased the solubility of [10]CPP in common organic solvents. The carrier-transport properties of thin films of [10]CPP and its derivatives were measured for the first time and indicated that [10]CPP derivatives could rival phenyl-C61-butyric acid methyl ester, which is used widely as an n-type active layer in bulk heterojunction photovoltaics.

AB - Nine organophosphate esters (OPEs) were investigated in air samples collected over the Bohai and Yellow Seas (East Asia) during a research cruise between June 28 and July 13, 2016. These same OPEs were quantified at a research site (North Huangcheng Island, NHI) in the middle of the Bohai Strait from May 16, 2015, to March 21, 2016. The median total OPE (SigmaOPE) concentration over the Bohai and Yellow Seas was 280 pg/m3. Tris(1-chloro-2-propyl) (TCPP) was the most abundant OPE, followed by tris(2-chloroethyl) phosphate (TCEP), tri-iso-butyl phosphate (TiBP), and tri-n-butyl phosphate (TnBP). Particle-bound OPEs accounted for 51 +/ 21% of the total OPEs. On NHI, the median SigmaOPE concentration was 210 pg/m3, and the average particle-bound fraction was 82 +/- 17%. For samples collected on NHI, significant negative linear correlations were found between the gaseous OPEs and 1/T (T: temperature (K)) (except TDCP, TPeP, and TCP). Among the 79 investigated samples, significant correlations between the measured OPE gas/particle partitioning coefficients (Kp,m) and subcooled liquid pressure (PL?) (p < 0.05) were found for only 14 samples, suggesting that OPEs have low potential to achieve equilibrium or ascribe to the artificial sampling. The annual dry deposition input of OPEs into the Bohai and Yellow Seas is estimated to be 12 tons/year.

AB - A series of six new cyclometalated iridium(III) complexes [Ir(ppy)2(N?N)][PF6] (ppy = 2-phenylpyridine) is reported herein. Proligands bis(pyridin-2-yl)sulfane (1a), 2,2'-sulfinyldipyridine (1b), 2,2'-sulfonyldipyridine (1c), bis(4 methylpyridin-2-yl)sulfane (2a), 2,2'-sulfinylbis(4-methylpyridine) (2b), and 2,2'-sulfonylbis(4-methylpyridine) (2c) were synthesized, characterized, and employed as the N?N ancillary ligand. Changing the oxidation state of the sulfur atom serves as a switch to alter the emissive state from that of mainly 3LC character (blue-green emission) to one of 3MLCT/3LLCT character (yellow emission). Sulfide and sulfoxide complexes Ir(1a), Ir(1b), Ir(2a), and Ir(2b) show identical, vibrationally structured emission profiles with maxima at 478, 510, 548 nm in CH2Cl2 solutions resulting from a 3LC state. In contrast, sulfone complexes Ir(1c) and Ir(2c) show broad, red-shifted 3CT emission (552 and 537 nm, respectively).

AB - Saccharomyces cerevisiae is used for edible purposes, such as human food or as an animal feed supplement. Fatty acids are also beneficial as feed supplements, but S. cerevisiae produces small amounts of fatty acids. In this study, we enhanced fatty acid production of S. cerevisiae by overexpressing acetyl-CoA carboxylase, thioesterase, and malic enzyme associated with fatty acid metabolism. The enhanced strain pAMT showed 2.4-fold higher fatty acids than the wild-type strain. To further increase the fatty acids, various nitrogen sources were analyzed and calcium nitrate was selected as an optimal nitrogen source for fatty acid production. By concentration optimization, 672 mg/L of fatty acids was produced, which was 4.7-fold higher than wild-type strain. These results complement the low level fatty acid production and make it possible to obtain the benefits of fatty acids as an animal feed supplement while, simultaneously, maintaining the advantages of S. cerevisiae.

AB - Intrinsically disordered proteins are characterized by their large manifold of thermally accessible conformations and their related statistical weights, making them an interesting target of simulation studies. To assess the development of a computational framework for modeling this distinct class of proteins, this work examines temperature-based replica-exchange simulations to generate a conformational ensemble of a 28-residue peptide from the Ebola virus protein VP35. Starting from a prefolded helix-beta-turn-helix topology observed in a crystallographic assembly, the simulation strategy tested is the recently refined CHARMM36m force field combined with a generalized Born solvent model. A comparison of two replica-exchange methods is provided, where one is a traditional approach with a fixed set of temperatures and the other is an adaptive scheme in which the thermal windows are allowed to move in temperature space. The assessment is further extended to include a comparison with equivalent CHARMM22 simulation data sets. The analysis finds CHARMM36m to shift the minimum in the potential of mean force (PMF) to a lower fractional helicity compared with CHARMM22, while the latter showed greater conformational plasticity along the helix-forming reaction coordinate. Among the simulation models, only the adaptive tempering method with CHARMM36m found an ensemble of conformational heterogeneity consisting of transitions between alpha-helix-beta-hairpin folds and unstructured states that produced a PMF of fractional fold propensity in qualitative agreement with circular dichroism experiments reporting a disordered peptide.

AB - Four new oxazole-containing diterpenoids, salvianans A-D (1-4), along with three known diterpenoids (5-7), were isolated from Salvia miltiorrhiza cell cultures. The structures of the new compounds were elucidated using spectroscopic methods and single-crystal X-ray diffraction. The evaluation for their anti-HIV-1 activities revealed that 2 and 3 displayed inhibitory activities with IC50 values of 0.03 and 1.2 MUM, respectively. The time of addition (TOA) assay and long terminal repeat (LTR) luciferase reporter assay results indicated that compound 2 was an HIV-1 transcription inhibitor and might be a lead compound of antiviral agents acting on HIV-1 transcription.

AB - The judicial placement of main group elements in conjugated structures is emerging as a key route to novel functional hybrid materials. We demonstrate here that the formation of B-N Lewis pairs at the periphery of anthracene leads to buckling of the backbone while also dramatically lowering the LUMO energy. The resulting BN-substituted contorted polycyclic aromatic hydrocarbons show large bathochromic shifts in the absorption and emission relative to all-carbon analogs. In the presence of light, they rapidly react with O2 without the need for an external photosensitizer, resulting in selective and reversible formation of the corresponding endoperoxides.

AB - Theories for the effective polarizability of a small particle in a medium are presented using different levels of approximation: we consider the virtual cavity, real cavity, and the hard-sphere models as well as a continuous interpolation of the latter two. We present the respective hard-sphere and cavity radii as obtained from density-functional simulations as well as the resulting effective polarizabilities at discrete Matsubara frequencies. This enables us to account for macroscopic media in van der Waals interactions between molecules in water and their Casimir-Polder interaction with an interface. PMID- 29185740 TI - Single-Molecule Fluorescence Reveals Commonalities and Distinctions among Natural and in Vitro-Selected RNA Tertiary Motifs in a Multistep Folding Pathway. AB - Decades of study of the RNA folding problem have revealed that diverse and complex structured RNAs are built from a common set of recurring structural motifs, leading to the perspective that a generalizable model of RNA folding may be developed from understanding of the folding properties of individual structural motifs. We used single-molecule fluorescence to dissect the kinetic and thermodynamic properties of a set of variants of a common tertiary structural motif, the tetraloop/tetraloop-receptor (TL/TLR). Our results revealed a multistep TL/TLR folding pathway in which preorganization of the ubiquitous AA platform submotif precedes the formation of the docking transition state and tertiary A-minor hydrogen bond interactions form after the docking transition state. Differences in ion dependences between TL/TLR variants indicated the occurrence of sequence-dependent conformational rearrangements prior to and after the formation of the docking transition state. Nevertheless, varying the junction connecting the TL/TLR produced a common kinetic and ionic effect for all variants, suggesting that the global conformational search and compaction electrostatics are energetically independent from the formation of the tertiary motif contacts. We also found that in vitro-selected variants, despite their similar stability at high Mg2+ concentrations, are considerably less stable than natural variants under near-physiological ionic conditions, and the occurrence of the TL/TLR sequence variants in Nature correlates with their thermodynamic stability in isolation. Overall, our findings are consistent with modular but complex energetic properties of RNA structural motifs and will aid in the eventual quantitative description of RNA folding from its secondary and tertiary structural elements.

AB - Complex Fe(bpyB)3 (1, bpyB = 5,5'-bis(dimesitylboranyl)-2,2'-bipyridine) and its reduced species [(18-c-6)K(THF)2].[Fe(bpyB)3] (2) were synthesized. Their solid state and electronic structures were investigated by single crystal X-ray crystallography, electron paramagnetic resonance and UV-vis spectroscopy, and SQUID measurements. In 1 two bpyB radical anions are fused by a diamagnetic FeII ion, whereas in 2 all three bpyB ligands are in the radical state. Complex 1 possesses an open-shell singlet ground state with a singlet-triplet gap of 0.18 kcal mol-1 and 2 features an open-shell doublet ground state with a doublet quartet gap of 1.4 kcal mol-1, as determined by SQUID measurements. The unpaired electrons in 1 and 2 mainly delocalize over the boron atoms and the bipyrdine moieties with negligible spin density at the iron center. Complex 2 represents the first isolable example of boron-based triradicals.

AB - Following isolation of the polyhydroxy compound, ostreol B, from cultivated cells of the toxic dinoflagellate Ostreopsis cf. ovata collected in South Korea, 1D and 2D NMR spectroscopy were employed to determine the planar chemical structure of this compound, which contained a tetrahydropyran ring, two terminal double bonds, and 21 hydroxyl groups. The absolute configurations of all stereogenic carbon centers in ostreol B were then determined through a combination of the J-based configuration analysis, rotating frame Overhauser effect correlations, and the modified Mosher method following cleavage of the 1,2-diol bonds. Ostreol B was also found to exhibit moderate cytotoxicity in HepG2, Neuro-2a and HCT-116 cells.

AB - The discovery of ionic current rectification (ICR) phenomena in synthetic nanofluidic systems elicits broad interest from interdisciplinary fields of chemistry, physics, materials science, and nanotechnology; and thus, boosts their applications in, for example, chemical sensing, fluidic pumping, and energy related aspects. So far, it is generally accepted that the ICR effect stems from the broken symmetry either in the nanofluidic structures, or in the environmental conditions. Although this empirical regularity is supported by numerous experimental and theoretical results, great challenge still remains to precisely figure out the correlation between the asymmetric ion transport properties and the degree of symmetry breaking. An appropriate and quantified measure is therefore highly demanded. Herein, taking DNA-stuffed nanopores as a model system, we systematically investigate the evolution of dynamic ICR in between two symmetric states. The fully stuffed and fully opened nanopores are symmetric; therefore, they exhibit linear ion transport behaviors. Once the stuffed DNA superstructures are asymmetrically removed from one end of the nanopore via aptamer-target interaction, the nanofluidic system becomes asymmetric and starts to rectify ionic current. The peak of ICR is found right before the breakthrough of the stuffed DNA forest. After that, the nanofluidic system gradually retrieves symmetry, and becomes non-rectified. Theoretical results by both the coarse grained Poisson-Nernst-Planck model and the 1D statistic model excellently support the experimental observations, and further establish a quantified correlation between the ICR effect and the degree of asymmetry for different molecular filling configurations. Based on the ICR properties, we develop a proof of-concept demonstration for sensing ATP, termed the ATP balance. These findings help to clarify the origin of ICR, and show implications to other asymmetric transport phenomena for future innovative nanofluidic devices and materials.

AB - To increase the functionality and broaden the potential application of neokestose, neokestose laurate was biosynthesized using Candida antarctica lipase B as biocatalyst, for which a mixture of 20% DMSO in 2-methyl-2-butanol (v/v) was chosen as the reaction medium. The optimum conditions for biosynthesis were as follows: a molar ratio of vinyl laurate to neokestose of 12, a temperature of 50 degrees C, molecular sieves of 100 g/L, and enzyme loading of 10 g/L. Under the optimal conditions, the conversion rate was achieved over 80%. The synthesized chemical 6'-O-lauroylneokestose confirmed by nuclear magnetic resonance (NMR) exhibited good emulsification with critical micelle concentration (CMC) of 352 MUM and broad antibacterial activity against Gram-positive bacteria such as Staphylococcus aureus, Listeria monocytogenes, Streptococcus mutans, Bacillus subtilis, and Bacillus cereus. Conclusively, 6'-O-lauroylneokestose was evidenced to be a dual-functional agent with emulsification and antibacterial activity, showing promising application potential in the food industry.

AB - Three series of biarylpyrazole imidazole and triazoles are described, which vary in the linker between the biaryl pyrazole and imidazole/triazole group. The imidazole and triazole series with the short -CH2- linker displayed promising antimycobacterial activity, with the imidazole-CH2- series (7) showing low MIC values (6.25-25 MUg/mL), which was also influenced by lipophilicity. Extending the linker to -C(O)NH(CH2)2- resulted in a loss of antimycobacterial activity. The binding affinity of the compounds with CYP121A1 was determined by UV-visible optical titrations with KD values of 2.63, 35.6, and 290 MUM, respectively, for the tightest binding compounds 7e, 8b, and 13d from their respective series. Both binding affinity assays and docking studies of the CYP121A1 inhibitors suggest type II indirect binding through interstitial water molecules, with key binding residues Thr77, Val78, Val82, Val83, Met86, Ser237, Gln385, and Arg386, comparable with the binding interactions observed with fluconazole and the natural substrate dicyclotyrosine.

PMID- 29185748 TI - 4-Aminoquinoline Antimalarials Containing a Benzylmethylpyridylmethylamine Group Are Active against Drug Resistant Plasmodium falciparum and Exhibit Oral Activity in Mice. AB - Emergence of drug resistant Plasmodium falciparum including artemisinin-tolerant parasites highlights the need for new antimalarials. We have previously shown that dibemequines, 4-amino-7-chloroquinolines with dibenzylmethylamine (dibemethin) side chains, are efficacious. In this study, analogues in which the terminal phenyl group of the dibemethin was replaced with a 2-pyridyl group and in which the 4-amino-7-chloroquinoline was either maintained or replaced with a 4 aminoquinoline-7-carbonitrile were synthesized in an effort to improve druglikeness. These compounds exhibited significantly improved solubility and decreased lipophilicity and were potent against chloroquine-sensitive (NF54) and resistant (Dd2 and 7G8) P. falciparum strains with 5/6 having IC50 < 100 nM against the NF54 strain. All inhibited both beta-hematin (synthetic hemozoin) formation and hemozoin formation in the parasite. Parasitemia was reduced by over 90% in P. berghei infected mice in 3/6 derivatives following oral dosing at 4 * 30 mg/kg, with microsomal metabolic stability data suggesting that this could be attributed to highly active metabolites. PMID- 29185749 TI - Energy Transfer to the Hydrogen Bond in the (H2O)2 + H2O Collision. AB - Trajectory procedures are used to study the collision between the vibrationally excited H2O and the ground-state (H2O)2 with particular reference to energy transfer to the hydrogen bond through the inter- and intramolecular pathways. In nearly 98% of the trajectories, energy transfer processes occur on a subpicosecond scale (<=0.7 ps). The H2O transfers approximately three-quarters of its excitation energy to the OH stretches of the dimer. The first step of the intramolecular pathway in the dimer involves a near-resonant first overtone transition from the OH stretch to the bending mode. The energy transfer probability in the presence of the 1:2 resonance is 0.61 at 300 K. The bending mode then redistributes its energy to low-frequency intermolecular vibrations in a series of small excitation steps, with the pathway which results in the hydrogen-bonding modes gaining most of the available energy. The hydrogen bonding in ~50% of the trajectories ruptures on vibrational excitation, leaving one quantum in the bend of the monomer fragment. In a small fraction of trajectories, the duration of collision is longer than 1 ps, during which the dimer and H2O form a short-lived complex through a secondary hydrogen bond, which undergoes large amplitude oscillations. PMID- 29185750 TI - Carbon Dots-Plasmonics Coupling Enables Energy Transfer and Provides Unique Chemical Signatures. AB - Plasmonic nanostructures and carbon dots (C-dots) are fascinating optical materials, utilized in imaging, sensing, and color generation. Interaction between plasmonic materials and C-dots may lead to new hybrid materials with controllable optical properties. Herein, we demonstrate for the first time coupling between plasmonic modes and C-dots deposited upon a plasmonic silver hole array. The coupling leads to a remarkable visual attenuation and shifts of the plasmonic wavelengths (i.e., color tuning). In particular, the C-dots-plasmon couplings and pertinent color transformations depend both upon the C-dots' fluorescence emission wavelengths and functional residues displayed upon the C dots' surface. This optical modulation corresponds to energy level alignment and consequent energy transfer between the C-dots and the plasmonic silver hole array. Notably, the energy coupling observed in the C-dot-plasmonic hybrid system allows distinguishing between C-dots species exhibiting similar optical properties, albeit displaying different functional residues.

PMID- 29185752 TI - Hydrogenation Facilitates Proton Transfer through Two-Dimensional Honeycomb Crystals. AB - Recent experiments have triggered a debate about the ability of protons to transfer easily through individual layers of graphene and hexagonal boron nitride (h-BN). However, state-of-the-art computer calculations have shown that the barriers to proton penetration can, at >3 eV, be excessively high. Despite considerable interest the origin of this apparent anomaly between experiment and simulation remains unclear. We offer a new perspective on this debate and show on the basis of first-principles calculations that the barrier for proton penetration is significantly reduced, to <1 eV, upon hydrogenation, even in the absence of pinholes in the lattice. Although hydrogenation has not been offered as an explanation before, analysis reveals that the barrier is reduced because hydrogenation destabilizes the initial state (a deep-lying chemisorption state) and expands the honeycomb lattice through which the protons penetrate. This study offers a rationalization of the fast proton transfer observed in experiments and highlights the ability of proton transport through single-layer materials in hydrogen-rich solutions. PMID- 29185753 TI - Density Functional Computations and Molecular Dynamics Simulations of the Triethylammonium Triflate Protic Ionic Liquid. AB - Systematic molecular dynamics simulations based on an empirical force field have been carried out for samples of triethylammonium trifluoromethanesulfonate (triethylammonium triflate, [TEA][Tf]), covering a wide temperature range 200 K <= T <= 400 K and analyzing a broad set of properties, from self-diffusion and electrical conductivity to rotational relaxation and hydrogen-bond dynamics. The study is motivated by recent quasi-elastic neutron scattering and differential scanning calorimetry measurements on the same system, revealing two successive first order transitions at T ~ 230 and 310 K (on heating), as well as an intriguing and partly unexplained variety of subdiffusive motions of the acidic proton. Simulations show a weakly discontinuous transition at T = 310 K and highlight an anomaly at T = 260 K in the rotational relaxation of ions that we identify with the simulation analogue of the experimental transition at T = 230 K. Thus, simulations help identifying the nature of the experimental transitions, confirming that the highest temperature one corresponds to melting, while the one taking place at lower T is a transition from the crystal, stable at T <= 260 K, to a plastic phase (260 <= T <= 310 K), in which molecules are able to rotate without diffusing. Rotations, in particular, account for the subdiffusive motion seen at intermediate T both in the experiments and in the simulation. The structure, distribution, and strength of hydrogen bonds are investigated by molecular dynamics and by density functional computations. Clustering of ions of the same sign and the effect of contamination by water at 1% wgt concentration are discussed as well.

AB - We use steady-state and ultrafast nonlinear spectroscopies in combination with density functional theory calculations to explain light emission below the optical gap energy (Eo) of crystalline samples of 5,12-diphenyl tetracene (DPT). In particular, the properties of vibrational coherences imprinted on a probe pulse transmitted through a DPT single crystal indicate discrete electronic transitions below Eo of this organic semiconductor. Analysis of coherence spectra leads us to propose structural defect states give rise to these discrete transitions and subgap light emission. We use the polarization dependence of vibrational coherence spectra to tentatively assign these defects in our DPT samples. Our results provide fundamental insights into the properties of midgap states in organic materials important for their application in next-generation photonics and optoelectronics technologies. PMID- 29185755 TI - VDAC1 and SERCA3 Mediate Progesterone-Triggered Ca2+ Signaling in Breast Cancer Cells. AB - Progesterone is a biphasic hormone whose confounding role in breast cancer cells involves an initial proliferative surge, followed by sustained growth arrest. Recently we reported that progesterone induces a time- and concentration dependent release of reactive oxygen species and thus regulates the antiproliferative activity in the breast cancer cell line. Furthermore, the expression of p27, a crucial cell cycle control protein, was regulated by binding of progesterone on progesterone receptor B, thus leading to antiproliferative signaling via multiple signaling pathways including p53, PTEN, and antioxidant systems. Here, we performed an LC-MS/MS analysis of three different breast cancer cell lines. Bioinformatics data analysis and functional classification of proteins revealed a role of progesterone in calcium signaling in MCF-7 cells, and the major differentially expressed calcium regulators were S100A11, S100A10, calreticulin, VDAC1, SERCA3, and SERCA1. Later on we confirmed it by a cell-line based system having a calcium cameleon sensor targeted at endoplasmic reticulum and found moderate calcium efflux from endoplasmic reticulum upon progesterone treatment. Real-time PCR, Western blot, and TMRM staining confirmed the role of calcium signaling regulators VDAC1 and SERCA3 in progesterone response. Taking together all of these results with our previous studies, we suggest that progesterone, by regulating important proteins involved in calcium signaling and transport, can modulate cell proliferation and cell death. Furthermore, our research may open new avenues for the hypothesis that surgery conducted during the luteal phase of the menstrual cycle might facilitate improved patient survival. PMID- 29185756 TI - Supramolecular Polymerization of N,N',N",N'''-tetra-(Tetradecyl)-1,3,6,8 pyrenetetracarboxamide: A Computational Study. AB - The role of molecular dipole orientations and intermolecular interactions in a derivative of pyrene on its supramolecular self-assembly in solution has been investigated using quantum chemical and force field based computational approaches. Five possible dipole configurations of the molecule have been examined, among which the one in which adjacent dipole vectors are antiparallel to each other is determined to be the ground state, on electrostatic grounds. Self-assembly of this molecule under realistic conditions has been studied using MD simulations. Dipolar relaxation in its liquid crystalline (LC) phase has been investigated and contrasted against that in the well-established benzene-1,3,5 tricarboxamide (BTA) family. The dihedral barrier related to the amide dipole flip is larger in the pyrene system than in BTA which explains the differences in their dipolar relaxation behaviors. The mechanism underlying polarization switching upon the application of an external electric field in the LC phase is investigated. Unlike in BTA, this switching is not associated with a reversal of the helical sense of the hydrogen bonded chains, due to differences in molecular symmetry. The observations enable general conclusions on the relationship between electric field induced chiral enhancement and symmetry to be drawn. PMID- 29185757 TI - Quantum Redirection of Antenna Absorption to Photosynthetic Reaction Centers. AB - The early steps of photosynthesis involve the photoexcitation of reaction centers (RCs) and light-harvesting (LH) units. Here, we show that the historically overlooked excitonic delocalization across RC and LH pigments results in a redistribution of absorption amplitudes that benefits the absorption cross section of the optical bands associated with the RC of several species. While we prove that this redistribution is robust to the microscopic details of the dephasing between these units in the purple bacterium Rhodospirillum rubrum, we are able to show that the redistribution witnesses a more fragile, but persistent, coherent population dynamics which directs excitations from the LH toward the RC units under incoherent illumination and physiological conditions. Even though the redirection does not seem to affect importantly the overall efficiency in photosynthesis, stochastic optimization allows us to delineate clear guidelines and develop simple analytic expressions in order to amplify the coherent redirection in artificial nanostructures. PMID- 29185758 TI - pH-Dependent Singlet O2 Oxidation Kinetics of Guanine and 9-Methylguanine: An Online Mass Spectrometry and Spectroscopy Study Combined with Theoretical Exploration. AB - We report a kinetic and mechanistic study on the title reactions, in which 1O2 was generated by the reaction of H2O2 with Cl2 and bubbled into an aqueous solution of guanine and 9-methylguanine (9MG) at different pH values. Oxidation kinetics and product branching ratios were measured using online electrospray ionization mass spectrometry coupled with absorption and emission spectrophotometry, and product structures were determined by collision-induced dissociation (CID) tandem mass spectrometry. Experiments revealed strong pH dependence of the reactions. The oxidation of guanine is noticeable only in basic solution, while the oxidation of 9MG is weak in acidic solution, increases in neutral solution, and becomes intensive in basic solution. 5-Guanidinohydantoin (Gh) and spiroiminodihydantoin (Sp) were detected as the major oxidation products of guanine and 9MG, and Sp became dominant in basic solution. A reaction intermediate was captured in mass spectra, and assigned to gem-diol on the basis of CID measurements. This intermediate served as the precursor for the formation of Gh. After taking into account solution compositions at each pH, first-order oxidation rate constants were extracted for individual species: that is, 3.2-3.6 * 107 M-1 s-1 for deprotonated guanine, and 1.2 * 106 and 4.6-4.9 * 107 M-1 s-1 for neutral and deprotonated 9MG, respectively. Guided by approximately spin projected density-functional-theory-calculated reaction potential energy surfaces, the kinetics for the initial 1O2 addition to guanine and 9MG was evaluated using transition state theory (TST). The comparison between TST modeling and experiment confirms that 1O2 addition is rate-limiting for oxidation, which forms endoperoxide and peroxide intermediates as determined in previous measurements of the same systems in the gas phase.

PMID- 29185760 TI - Heterogeneous Kinetics in the Functionalization of Single Plasmonic Nanoparticles. AB - The functionalization of gold nanoparticles with DNA has been studied extensively in solution; however, these ensemble measurements do not reveal particle-to particle differences. Here we study the functionalization of gold nanorods with thiolated single-stranded DNA (ssDNA) at the single-particle level. We exploit the sensitivity of the plasmon resonance to the local refractive index to study the functionalization in real time using single-particle spectroscopy. We find particle-to-particle variations of the plasmon shift that are attributed to the particle size distribution and variations in ssDNA coverage. We find that the ssDNA coverage varies by ~10% from particle to particle, beyond the expected variation due to Poisson statistics. Surprisingly, we find binding rates that differ from particle to particle by an order of magnitude, even though the buffer conditions are identical. We ascribe this heterogeneity to a distribution of activation energies caused by particle-to-particle variations in effective surface charge. These results yield insight into the kinetics of biofunctionalization at the single particle level and highlight that significant kinetic heterogeneity has to be taken into account in applications of functional particles. The presented methodology is easily extended to any nanoparticle coating and can be used to optimize functionalization protocols.

PMID- 29185763 TI - Enhanced Electron Mobility in Nonplanar Tensile Strained Si Epitaxially Grown on SixGe1-x Nanowires. AB - We report the growth and characterization of epitaxial, coherently strained SixGe1-x-Si core-shell nanowire heterostructure through vapor-liquid-solid growth mechanism for the SixGe1-x core, followed by an in situ ultrahigh-vacuum chemical vapor deposition for the Si shell. Raman spectra acquired from individual nanowire reveal the Si-Si, Si-Ge, and Ge-Ge modes of the SixGe1-x core and the Si Si mode of the shell. Because of the compressive (tensile) strain induced by lattice mismatch, the core (shell) Raman modes are blue (red) shifted compared to those of unstrained bare SixGe1-x (Si) nanowires, in good agreement with values calculated using continuum elasticity model coupled with lattice dynamic theory. A large tensile strain of up to 2.3% is achieved in the Si shell, which is expected to provide quantum confinement for electrons due to a positive core-to shell conduction band offset. We demonstrate n-type metal-oxide-semiconductor field-effect transistors using SixGe1-x-Si core-shell nanowires as channel and observe a 40% enhancement of the average electron mobility compared to control devices using Si nanowires due to an increased electron mobility in the tensile strained Si shell.

AB - Although they are currently unregulated, atmospheric ultrafine particles (<100 nm) pose health risks because of, e.g., their capability to penetrate deep into the respiratory system. Ultrafine particles, often minor contributors to atmospheric particulate mass, typically dominate aerosol particle number concentrations. We simulated the response of particle number concentrations over Europe to recent estimates of future emission reductions of aerosol particles and their precursors. We used the chemical transport model PMCAMx-UF, with novel updates including state-of-the-art descriptions of ammonia and dimethylamine new particle formation (NPF) pathways and the condensation of organic compounds onto particles. These processes had notable impacts on atmospheric particle number concentrations. All three emission scenarios (current legislation, optimized emissions, and maximum technically feasible reductions) resulted in substantial (10-50%) decreases in median particle number concentrations over Europe. Consistent reductions were predicted in Central Europe, while Northern Europe exhibited smaller reductions or even increased concentrations. Motivated by the improved NPF descriptions for ammonia and methylamines, we placed special focus on the potential to improve air quality by reducing agricultural emissions, which are a major source of these species. Agricultural emission controls showed promise in reducing ultrafine particle number concentrations, although the change is nonlinear with particle size.

AB - Nanoarchitecture of bismuth vanadate (BiVO4) photoanodes for effectively increasing light harvesting efficiency and simultaneously achieving high charge separation efficiency is the key to approaching their theoretic performance of solar-driven water splitting. Here, we developed hierarchical BiVO4 nanoporous sphere arrays, which are composed of small nanoparticles and sufficient voids for offering high capability of charge separation. Significantly, multiple light scattering in the sphere arrays and voids along with the large effective thickness of the BiVO4 photoanode induce efficient light harvesting. In addition, attributed to ultrathin two-dimensional Bi2WO6 nanosheets as the precursor, the synergy of various enhancement strategies including WO3/BiVO4 nanojunction formation, W-doping, and oxygen vacancy creation can be directly incorporated into such a unique hierarchical architecture during the one-step synthesis of BiVO4 without complex pre- or post-treatment. The as-obtained photoanode exhibits a water splitting photocurrent of 5.5 mA cm-2 at 1.23 V versus RHE under 1-sun illumination, among the best values reported up-to-date in the field. PMID- 29185765 TI - Designing Diameter-Modulated Heterostructure Nanowires of PbTe/Te by Controlled Dewetting. AB - Heterostructures consisting of semiconductors with controlled morphology and interfaces find applications in many fields. A range of axial, radial, and diameter-modulated nanostructures have been synthesized primarily using vapor phase methods. Here, we present a simple wet chemical routine to synthesize heterostructures of PbTe/Te using Te nanowires as templates. A morphology evolution study for the formation of these heterostructures has been performed. On the basis of these control experiments, a pathway for the formation of these nanostructures is proposed. Reduction of a Pb precursor to Pb on Te nanowire templates followed by interdiffusion of Pb/Te leads to the formation of a thin shell of PbTe on the Te wires. Controlled dewetting of the thin shell leads to the formation of cube-shaped PbTe that is periodically arranged on the Te wires. Using control experiments, we show that different reactions parameters like rate of addition of the reducing agent, concentration of Pb precursor and thickness of initial Te nanowire play a critical role in controlling the spacing between the PbTe cubes on the Te wires. Using simple surface energy arguments, we propose a mechanism for the formation of the hybrid. The principles presented are general and can be exploited for the synthesis of other nanoscale heterostructures.

AB - Molecular iodine catalyzes a cyclization of N-aryl-2-alkynylanilines, which proceeds through the iodocyclization of 2-alkynylanilines followed by the protodeiodination of the iodocyclized intermediates at room temperature. Furthermore, the molecular iodine catalysis can be applied to the cascade cyclization of 2-(enynyl)aniline and to the tandem cyclization-addition reaction of 2-alkynylanilines with alpha,beta-enones.

PMID- 29185768 TI - Focused Genome Mining of Structurally Related Sesterterpenes: Enzymatic Formation of Enantiomeric and Diastereomeric Products. AB - Heterologous expression of four clade-A bifunctional terpene synthases (BFTSs), giving di/sesterterpenes with unique polycyclic carbon skeletons such as sesterfisherol, enabled the isolation of the sesterterpenes Bm1, Bm2, Bm3, and Pb1. Their structures suggested that formation of the products occurs via various diastereomeric carbocation intermediates, allowing the proposal that clade-A BFTSs catalyze three-step cyclizations using several stereofacial combinations of allylic cation-olefin pairs in the corresponding intermediates to generate various stereoisomers. PMID- 29185769 TI - Drug Repurposing Approach Identifies a Synergistic Drug Combination of an Antifungal Agent and an Experimental Organometallic Drug for Melanoma Treatment. AB - By screening a drug library comprising FDA approved compounds, we discovered a potent interaction between the antifungal agent haloprogin and the experimental organometallic drug RAPTA-T, to synergistically induce cancer cell killing. The combination of these two small molecules, even at low doses, elicited an improved therapeutic response on tumor growth over either agent alone or the current treatment used in the clinic in the highly aggressive syngeneic B16F10 melanoma tumor model, where classical cytotoxic chemotherapeutic agents show little efficacy. The combination with the repurposed chemodrug haloprogin provides the basis for a new powerful treatment option for cutaneous melanoma. Importantly, because synergistic induction of tumor cell death is achieved with low individual drug doses, and cellular targets for RAPTA-T are different from those of classical chemotherapeutic drugs, a therapeutic strategy based on this approach could avoid toxicities and potentially resistance mechanisms, and could even inhibit metastatic progression. PMID- 29185770 TI - Producing Atomically Abrupt Axial Heterojunctions in Silicon-Germanium Nanowires by Thermal Oxidation. AB - Compositional abruptness of the interfaces is one of the important factors to determine the performance of Group IV semiconductor heterojunction (Si/Ge or Si/SiGe) nanowire devices. However, forming abrupt interfaces in the nanowires using the common vapor-liquid-solid (VLS) method is restricted because large solubility of Si and Ge in the Au eutectic liquid catalyst makes gradual composition change at the heterojunction after switching the gas phase components. According to the VLS growth mechanism, another possible approach to form an abrupt interface is making a change of the semiconductor concentration in the eutectic liquid before precipitation of the second phase. Here we show that the composition in AuSiGe eutectic liquid on SiGe nanowires of low Ge concentration (<=6%) can be altered by thermal oxidation at 700 degrees C. During the oxidation process, only Si is oxidized on the surface of the eutectic liquid, and the Ge/Si ratio in the eutectic liquid is increased. The subsequently precipitated SiGe step at the liquid/solid interface has a higher Ge concentration (~20%), and a compositionally abrupt interface is produced in the nanowires. The growth mechanism of the heterojunction includes diffusion of Si and Ge atoms on nanowire surface into the AuSiGe eutectic liquid and step nucleation at the liquid/nanowire interface. PMID- 29185771 TI - Centimeter-Long Single-Crystalline Si Nanowires. AB - The elongation of free-standing one-dimensional (1D) functional nanostructures into lengths above the millimeter range has brought new practical applications as they combine the remarkable properties of nanostructured materials with macroscopic lengths. However, it remains a big challenge to prepare 1D silicon nanostructures, one of the most important 1D nanostructures, with lengths above the millimeter range. Here we report the unprecedented preparation of ultralong single-crystalline Si nanowires with length up to 2 cm, which can function as the smallest active material to facilitate the miniaturization of macroscopic devices. These ultralong Si nanowires with augmented flexibility are of emerging interest for flexible electronics. We also demonstrate the first single-nanowire based wearable joint motion sensor with superior performance to reported systems, which just represents one example of novel devices that can be built from these nanowires. The preparation of ultralong Si nanowires will stimulate the fabrication and miniaturization of electric, optical, medical, and mechanical devices to impact the semiconductor industry and our daily life in the near future. PMID- 29185772 TI - Six Stages of Microdroplet Detachment from Microscale Fibers. AB - The detachment of droplets from cylindrical fibers is of fundamental importance for both scientific research and engineering applications. Due to the challenges to determine dynamic contact angles on the fiber surface, the process of the droplet detachment from a fiber is not well understood. In this paper, a multibody dissipative particle dynamics (MDPD) method, a particle-based mesh-free method that can automatically capture the dynamic contact angles through direct modeling of liquid-solid particle interactions, was applied to study the detachment process of a liquid microdroplet from a cylindrical solid fiber pulled by an atomic force microscopy (AFM) tip under a constant velocity. After the validation of the numerical results through comparison with experiments in a benchmark case, the same numerical tool was applied to analyze the droplet detachment mechanisms. Based on the slope of the time history curve for the displacement of the droplet mass center, the detachment process can be divided into six stages. The change of slope in each stage can be explained from the change of surface energy. The results can greatly advance the fundamental understanding of the detachment process of microdroplets from cylindrical fibers.

AB - Homoisoflavonoids were formed in DMSO exclusively, and flavones were formed in t AmOH when salicylaldehyde and alkynoic acids reacted with [Ru(p-cymene)Cl2]2 and CsOAc. They were formed through C-H activation of salicylaldehyde and decarboxylative coupling of alkynoic acid. This reaction system showed good yields, broad substrate scope, and good functional group tolerance. It was found that chalcone was an intermediate in the formation of both homoisoflavonoid and flavone.

AB - An efficient silver-catalyzed [2 + 1] cyclopropanation of sterically hindered internal alkenes with diazo compounds in which room-temperature-decomposable N nosylhydrazones are used as diazo surrogates is reported. The unexpected unique catalytic activity of silver was ascribed to its dual role as a Lewis acid activating alkene substrates and as a transition metal forming silver carbenoids. A wide range of internal alkenes, including challenging diarylethenes, were suitable for this protocol, thereby affording a variety of cyclopropanes with high efficiency in a stereoselective manner under mild conditions.

PMID- 29185776 TI - Direct Room Temperature Welding and Chemical Protection of Silver Nanowire Thin Films for High Performance Transparent Conductors. AB - Silver nanowire (Ag-NW) thin films have emerged as a promising next-generation transparent electrode. However, the current Ag-NW thin films are often plagued by high NW-NW contact resistance and poor long-term stability, which can be largely attributed to the ill-defined polyvinylpyrrolidone (PVP) surface ligands and nonideal Ag-PVP-Ag contact at NW-NW junctions. Herein, we report a room temperature direct welding and chemical protection strategy to greatly improve the conductivity and stability of the Ag-NW thin films. Specifically, we use a sodium borohydride (NaBH4) treatment process to thoroughly remove the PVP ligands and produce a clean Ag-Ag interface that allows direct welding of NW-NW junctions at room temperature, thus greatly improving the conductivity of the Ag-NW films, outperforming those obtained by thermal or plasmonic thermal treatment. We further show that, by decorating the as-formed Ag-NW thin film with a dense, hydrophobic dodecanethiol layer, the stability of the Ag-NW film can be greatly improved by 150-times compared with that of PVP-wrapped ones. Our studies demonstrate that a proper surface ligand design can effectively improve the conductivity and stability of Ag-NW thin films, marking an important step toward their applications in electronic and optoelectronic devices. PMID- 29185777 TI - Systematic Testing of Belief-Propagation Estimates for Absolute Free Energies in Atomistic Peptides and Proteins. AB - Motivated by the extremely high computing costs associated with estimates of free energies for biological systems using molecular simulations, we further the exploration of existing "belief propagation" (BP) algorithms for fixed-backbone peptide and protein systems. The precalculation of pairwise interactions among discretized libraries of side-chain conformations, along with representation of protein side chains as nodes in a graphical model, enables direct application of the BP approach, which requires only ~1 s of single-processor run time after the precalculation stage. We use a "loopy BP" algorithm, which can be seen as an approximate generalization of the transfer-matrix approach to highly connected (i.e., loopy) graphs, and it has previously been applied to protein calculations. We examine the application of loopy BP to several peptides as well as the binding site of the T4 lysozyme L99A mutant. The present study reports on (i) the comparison of the approximate BP results with estimates from unbiased estimators based on the Amber99SB force field; (ii) investigation of the effects of varying library size on BP predictions; and (iii) a theoretical discussion of the discretization effects that can arise in BP calculations. The data suggest that, despite their approximate nature, BP free-energy estimates are highly accurate indeed, they never fall outside confidence intervals from unbiased estimators for the systems where independent results could be obtained. Furthermore, we find that libraries of sufficiently fine discretization (which diminish library-size sensitivity) can be obtained with standard computing resources in most cases. Altogether, the extremely low computing times and accurate results suggest the BP approach warrants further study. PMID- 29185778 TI - Extent of Surface Force Additivity on Chemically Heterogeneous Substrates at Varied Orientations. AB - Surface interactions between chemically mixed surfaces, as well as those among dissolved biomolecules, comprise distinct contributions from polar and hydrophobic moieties. These contributions are often context dependent. Approximate compliance to the Cassie additivity equation for the wetting free energies on mixed surfaces in water is, however, indicative of similarly additive forces between individual surface elements, suggesting a quadratic interpolation model for total force from the forces between pure surfaces. We use molecular dynamics/umbrella sampling simulations of parallel and nonparallel mixed surfaces with demonstrable Cassie-like behavior to verify how well the total surface force between the heterogeneous, molecularly rough surfaces can be approximated as a combination of forces among the homogeneous ones. When accounting for dissimilar distances of approach between functional groups of different types, our results for graphene surfaces with mixed methyl and nitrile coating show such a superposition to provide a reasonable first order approximation of interactions between the platelets. Deviations from additivity are more prominent in parallel plate configurations, at high content of hydrophobic groups, and small separations. The inclusion of water polarizability does not visibly alter the observed behavior regardless of platelet orientations. The outcome of this study determines the necessary molecular conditions for observing force additivity that emphasize the context dependence of hydrophobic interaction in the presence of polar groups. This notion provides guidelines for the syntheses of new, chemically heterogeneous materials with tailored function-oriented properties in aqueous media. PMID- 29185780 TI - Effects of Saffron on Cognition, Anxiety, and Depression in Patients Undergoing Coronary Artery Bypass Grafting: A Randomized Double-Blind Placebo-Controlled Trial. AB - OBJECTIVES: Cognitive decline, depression, and anxiety are among the major concerns in patients undergoing coronary artery bypass grafting (CABG). Crocus sativus L. (saffron) seems to be a promising candidate for treatment of these conditions. DESIGN: In this 12-week, randomized, double-blind, placebo-controlled clinical trial, men and women with on-pump CABG, who had Wechsler Memory Scale (WMS) score >70 and age <70 years, received either saffron capsules (15 mg/twice daily) or placebo. Patients were excluded if they had history of treatment with saffron or acetylcholinesterase inhibitors, comorbid neuropsychiatric disorders, serious medical conditions other than cardiovascular diseases, and hypersensitivity to herbal compounds. The primary outcome was defined as the difference in mean total score changes for WMS-Revised from the baseline to week 12 between the saffron and placebo groups. Secondary outcomes included difference in mean score changes from baseline to endpoint between the two treatment groups for Mini Mental Status Examination and subscales of Hospital Anxiety and Depression Scale ( www.irct.ir ; IRCT201408071556N63). RESULTS: No significant difference was detected in primary or secondary outcomes between the saffron and placebo groups. Also, no significant time * treatment interaction effect was found for any of the scales. CONCLUSIONS: The results of this trial do not support the hypothesis of potential benefits of saffron in treatment of CABG related neuropsychiatric conditions. PMID- 29185779 TI - Quasi-Two-Dimensional Phase Transition of Methane Adsorbed in Cylindrical Silica Mesopores. AB - Using Monte Carlo and molecular dynamics simulations, we examine the adsorption of methane in cylindrical silica mesopores in an effort to understand a possible phase transition of adsorbed methane in MCM-41 and SBA-15 silica that was previously identified by an unexpected increase in the adsorbed fluid density following capillary condensation, as measured by small-angle neutron scattering (SANS) [Chiang, W-S., et al., Langmuir 2016, 32, 8849]. Our initial simulation results identify a roughly 10 % increase in the density of the liquidlike adsorbed phase for either an isotherm with increasing pressure or an isobar with decreasing temperature and that this densification is associated with a local maximum in the isosteric enthalpy of adsorption. Subsequent analysis of the simulated fluid, via computation of bond-orientational order parameters of specific annular layers of the adsorbed fluid, showed that the layers undergo an ordering transition from a disordered, amorphous state to one with two dimensional hexagonal structure. Furthermore, this two-dimensional restructuring of the fluid occurs at the same thermodynamic state points as the aforementioned densification and local maximum in the isosteric enthalpy of adsorption. We thus conclude that the densification of the fluid is the result of structural reorganization, which is signaled by the maximum in the isosteric enthalpy. Owing to the qualitative similarity of the structural transitions in the simulated and experimental methane fluids, we propose this hexagonal reorganization as a plausible explanation of the densification observed in SANS measurements. Lastly, we speculate how this structural transition may impact the transport properties of the adsorbed fluid. PMID- 29185781 TI - Osteochondral Allograft Transplantation of the Knee in Patients Aged 40 Years and Older. AB - BACKGROUND: Treatment of large chondral defects of the knee among patients aged >=40 years remains a difficult clinical challenge owing to preexisting joint degeneration and the lack of treatment options short of arthroplasty. PURPOSE: To characterize the survivorship, predictors of failure, and clinical outcomes of osteochondral allograft transplantation (OCA) of the knee among patients aged >=40 years. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Prospectively collected data were reviewed for 54 consecutive patients aged >=40 years who were treated with OCA. Preoperative levels of osteoarthritis (according to Kellgren-Lawrence classification) and meniscal volume and quality were graded from review of radiographs and magnetic resonance imaging. Complications, reoperations, and patient responses to validated outcome measures were reviewed. A minimum follow-up of 2 years was required for analysis. Failure was defined by any removal or revision of the allograft or conversion to arthroplasty. RESULTS: Among 51 patients (mean age, 48 years; range, 40-63 years; 65% male), a total of 52 knees had symptomatic focal cartilage lesions (up to 2 affected areas) that were classified as Outerbridge grade 4 at the time of OCA and did not involve substantial bone loss requiring shell allografts or additional bone grafting. Mean duration of follow-up was 3.6 years (range, 2-11 years). After OCA, 21 knees (40%) underwent reoperation, including 14 failures (27%) consisting of revision OCA (n = 1), unicompartmental knee arthroplasty (n = 5), and total knee arthroplasty (n = 8). Mean time to failure was 33 months, and 2- and 4-year survivorship rates were 88% and 73%, respectively. Male sex (hazard ratio = 4.18, 95% CI = 1.12-27.13) and a higher number of previous ipsilateral knee operations (hazard ratio = 1.70 per increase in 1 surgical procedure, 95% CI = 1.03-2.83) were predictors of failure. A higher Kellgren-Lawrence osteoarthritis grade on preoperative radiographs was associated with higher failure rates in the Kaplan Meier analysis but not the multivariate model. At final follow-up, clinically significant improvements were noted in the pain (mean score, 47.8 to 67.6) and physical functioning (56.8 to 79.1) subscales of the Short Form-36, as well as the International Knee Documentation Committee subjective form (45.0 to 63.6), Knee Outcome Survey-Activities of Daily Living (64.5 to 80.1), and overall condition statement (4.5 to 6.8) ( P < .001). No significant changes were noted for the Marx Activity Rating Scale (5.1 to 3.9, P = .789). CONCLUSION: A higher failure rate was found in this series of patients aged >=40 years who were treated with OCA as compared with other studies of younger populations. However, for select older patients, OCA can be a good midterm treatment option for cartilage defects of the knee. PMID- 29185783 TI - Comparison of recidivism rates for a teenage trauma prevention program after the addition of high-fidelity patient simulation. AB - OBJECTIVES: We evaluated the benefits of adding high-fidelity simulation to a teenage trauma prevention program to decrease recidivism rates and encourage teens to discuss actionable steps toward safe driving. METHODS: A simulated pediatric trauma scenario was integrated into an established trauma prevention program. Participants were recruited because they were court-ordered to attend this program after misdemeanor convictions for moving violations. The teenage participants viewed this simulation from the emergency medical services (EMS) handoff to complete trauma care. Participants completed a postsimulation knowledge assessment and care evaluation, which included narrative data about the experience. Qualitative analysis of color-coded responses identified common themes and experiences in participants' answers. Court records were reviewed 6 years after course completion to determine short- and long-term recidivism rates, which were then compared to our program's historical rate. RESULTS: One hundred twenty-four students aged 16-20 years participated over a 2-year study period. Narrative responses included general reflection, impressions, and thoughts about what they might change as a result of the course. Participants reported that they would decrease speed (30%), wear seat belts (15%), decrease cell phone use (11%), and increase caution (28%). The recidivism rate was 55% within 6 years. At 6 months it was 8.4%, at 1 year it was 20%, and it increased approximately 5-8% per year after the first year. Compared with our programs, for historical 6-month and 2-year recidivism rates, no significant difference was seen with or without simulation. CONCLUSIONS: Adding simulation is well received by participants and leads to positive reflections regarding changes in risk-taking behaviors but resulted in no changes to the high recidivism rates This may be due to the often ineffectiveness of fear appeals. PMID- 29185782 TI - Reemergence of Blended Tube Feeding and Parent's Reported Experiences in Their Tube Fed Children. AB - OBJECTIVE: Healthcare providers (HCPs) report increased interest in blenderized tube feeding (BTF) as an alternative to commercial formula (CF) feeding particularly in families of tube fed children. The objective of this study was to explore parents' reported experiences of CF and BTF in their children. DESIGN: Prospective descriptive study utilizing a convenience sample. SETTING/SUBJECTS: Parents (n = 433) of tube fed children in an online tube feeding support group completed an electronic survey to compare experiences of CF and BTF in their tube fed children. RESULTS: The sample was evenly represented by parents using CF (50.5%) and BTF (49.5%). Reasons parents chose BTF included desire to provide whole foods (20.2%), decrease symptoms of tube feeding intolerance (19.7%), provide family meals (12.2%), increase oral intake (10.8%), address allergies (5.3%), or because they did not like formula (19.7%). Parents reported fewer symptoms of tube feeding intolerance on BTF and their children more frequently met growth goals compared to formula feeding. Only half (49.3%) of parents using BTF referred to HCPs for recipes and feeding oversight. The primary reasons parents did not use BTF included lack of knowledge (50.9%) or time constraints (20.0%). CONCLUSIONS: A significant number of parents in this sample successfully provide full or partial BTF to their children but only half rely on HCPs for guidance. There is wide variability in BTF preparation and delivery. Parents who use or have interest in BTF need knowledgeable and supportive HCPs for guidance and follow-up due to the unique nutritional needs of this patient population. HCPs need to be prepared to screen families of tube fed children who are using BTF or are interested in this feeding alternative to CF. Healthcare facilities need to evaluate their enteral feeding policies to accommodate patients on BTF. PMID- 29185784 TI - miR-21 Inhibitors Modulate Biological Functions of Gastric Cancer Cells via PTEN/PI3K/mTOR Pathway. AB - Gastric cancer is one of the most common malignancy in the world. microRNAs (miRNAs) are naturally occurring noncoding RNA that control gene expression by targeting messenger RNA (mRNA) for post-transcriptional repression or cleavage. This study focused on a specific miRNA, miR-21, which was overexpressed in gastric cancer and examined the effects of miR-21 inhibitor on biological functions of gastric cancer cells and its possible mechanism. Gastric cancer cells MKN74 were treated with miR-21 inhibitor, negative control, and blank control. Cell proliferation, colony formation, migration, and invasion were assessed. Real-time PCR and western blot were applied to examine the expression of phosphatase and tens in homolog deleted on chromosome ten (PTEN)/PI3K/mTOR pathway molecules. miR-21 inhibitor markedly suppressed proliferation, migration, invasion, and colony formation of gastric cancer cells. Anti-miR-21 treatment also reduced the expression ratio of B cell lymphoma 2 (Bcl-2)/Bax. Furthermore, miR-21 inhibition was associated with increased expression of PTEN, which in turn decreased the ratios of S235/236, S240/244, and p-AK/AKT in gastric cancer cells. Inhibiting miR-21 modulates biological functions of gastric cancer cells via PTEN/PI3K/mTOR pathway and miR-21 inhibitor may provide a novel therapeutic strategy for gastric cancer. PMID- 29185785 TI - Functional outcomes of motor vehicle crash thoracic injuries in pediatric and adult occupants. AB - OBJECTIVE: Characterization of the severity of injury should account for both mortality and disability. The objective of this study was to develop a disability metric for thoracic injuries in motor vehicle crashes (MVCs) and compare the functional outcomes between the pediatric and adult populations. METHODS: Disability risk (DR) was quantified using Functional Independence Measure (FIM) scores within the National Trauma Data Bank for the most frequently occurring Abbreviated Injury Scale (AIS) 2-5 thoracic injuries. Occupants with thoracic injury were classified as disabled or not disabled based on the FIM scale, and comparisons were made between the following age groups: pediatric, adult, middle aged, and older occupants (ages 7-18, 19-45, 46-65, and 66+, respectively). For each age group, DR was calculated by dividing the number of patients who were disabled and sustained a given injury by the number of patients who sustained a given injury. To account for the effect of higher severity co-injuries, a maximum AIS adjusted DR (DRMAIS) was also calculated for each injury. DR and DRMAIS could range from 0 to 100% disability risk. RESULTS: The mean DRMAIS for MVC thoracic injuries was 20% for pediatric occupants, 22% for adults, 29% for middle-aged adults, and 43% for older adults. Older adults possessed higher DRMAIS values for diaphragm laceration/rupture, heart laceration, hemo/pneumothorax, lung contusion/laceration, and rib and sternum fracture compared to the other age groups. The pediatric population possessed a higher DRMAIS value for flail chest compared to the other age groups. CONCLUSION: Older adults had significantly greater overall disability than each of the other age groups for thoracic injuries. The developed disability metrics are important in quantifying the significant burden of injuries and loss of quality life years. Such metrics can be used to better characterize severity of injury and further the understanding of age-related differences in injury outcomes, which can influence future age specific modifications to AIS. PMID- 29185786 TI - Desvenlafaxine Versus Placebo in the Treatment of Children and Adolescents with Major Depressive Disorder. AB - OBJECTIVE: To evaluate the short-term efficacy and safety of desvenlafaxine versus placebo in the treatment of children and adolescents with major depressive disorder (MDD). METHODS: Outpatient children (7-11 years) and adolescents (12-17 years) who met DSM-IV-TR criteria for MDD and had screening and baseline Children's Depression Rating Scale-Revised (CDRS-R) total scores >40 were randomly assigned to 8 weeks of treatment with placebo, low exposure desvenlafaxine (20, 30, or 35 mg/day based on baseline weight), or higher exposure desvenlafaxine (25, 35, or 50 mg/day based on baseline weight). The primary efficacy endpoint was change from baseline in CDRS-R total score at week 8, analyzed using a mixed-effects model for repeated measures. Secondary efficacy assessments included Clinical Global Impressions-Severity and Clinical Global Impressions-Improvement scales. Safety assessments included adverse events and the Columbia-Suicide Severity Rating Scale. RESULTS: The safety population included 363 patients (children, n = 109; adolescents, n = 254). No statistical separation from placebo was observed for either desvenlafaxine group for CDRS-R total score or for any secondary efficacy endpoint. At week 8, adjusted mean (standard error) changes from baseline in CDRS-R total score for the desvenlafaxine low exposure, desvenlafaxine high exposure, and placebo groups were -23.7 (1.1), -24.4 (1.1), and -22.9 (1.1), respectively. The incidence of adverse events was similar among groups. CONCLUSION: Low and high exposure desvenlafaxine groups did not demonstrate efficacy for the treatment of MDD in children and adolescents in this double-blind, placebo-controlled trial. Desvenlafaxine (20-50 mg/day) was generally safe and well tolerated with no new safety signals identified in pediatric patients with MDD in this study.

AB - BACKGROUND: Sedentary lifestyle is growing among children and adolescents that may contribute to problems such as overweight and obesity. Consequently, interventions to improve weight loss in this population are necessary. The aim of this current review was to evaluate the effectiveness of game-based interventions to reduce body mass index (BMI) among children who were overweight or obese. METHODS: All randomized controlled trials with a game-based approach for lowering weight in obese/overweight youths aged 5-18 years old were identified from January 2005 to June 2017 across PubMed, Web of Science, Embase, Scopus, and ScienceDirect. Two independent reviewers completed data extraction sheets on information such as sample size, country of origin, age of participants, type of interventions, and BMI change from pre- to posttest. A consensus on collected data was obtained, and a final list of studies meeting inclusion and exclusion criteria was arrived at. Data were analyzed using Comprehensive Meta-analysis software, and effect size was measured by standardized mean difference (SMD) and Hedges' g measure. Heterogeneity and publication bias were also examined using I2 index and funnel plot. RESULTS: A total of 388 articles were identified from electronic and manuals' searches. After deletion of duplicated articles, 138 articles remained that were then screened in terms of relevance. Of those, 41 articles were examined to determine eligibility. Finally, 10 articles met inclusion/exclusion criteria and were entered into the quantitative meta analysis. Results indicated a small but significant effect size in terms of BMI reduction [SMD, -0.234; standard error (SE), 0.069] among included studies. The average BMI z-score reduction was -0.181 (SE, 0.071). Trials which used other types of interventions along with active game-based approaches achieved greater effect sizes than single game-based interventions. There was a significant difference between studies based on their country of origin, BMI value, and intervention type. Those conducted in United States, those including participants with BMI >=30, and studies with multicomponent intervention reported a higher reduction of BMI than others. However, no significant difference in BMI was found in terms of variables such as age, sample size, type of participant (overweight/obese), intervention duration, or participant gender. No publication bias was identified, and studies were homogenous (I2 = 22.5%). CONCLUSIONS: Interventions that involve active gaming may produce small effects in terms of improving BMI among children who are overweight/obese. Therefore, we recommend that supplemental interventions be used to enhance the effectiveness of game based interventions. PMID- 29185788 TI - Risk factors for motorcycle loss-of-control crashes. AB - OBJECTIVE: The present article identifies and assesses the effect of critical factors on the risk of motorcycle loss-of-control (LOC) crashes. METHOD: Data come from a French project on road crashes, which include all fatal road crashes and a random sample of 1/20th of nonfatal crashes in France in 2011, based on police reports. A case-control study was carried out on a sample of 903 crashes for 444 LOC motorcycle riders (case) and 470 non-LOC and nonresponsible motorcycle riders (control). The sample was weighted due to the randomization of nonfatal crashes. Missing values were imputed using multiple imputation. RESULTS: Road alignment and surface conditions, human factors, and motorcycle type played important roles in motorcycle LOC crashes. Riding in a curve was associated with a 3-fold greater risk of losing control of motorcycle than riding in a straight line. Poor road adhesion significantly increased the risk of losing control; the risk increased more than 20-fold when deteriorated road adhesion was encountered unexpectedly, due to loose gravel, ice, oil, bumps, road marking, metal plates, etc. For motorcyclists, riding with a positive blood alcohol concentration (over or equal to the legal limit of 0.5 g/L) was very dangerous, often resulting in losing control. The risk of LOC crash varied for different types of motorcycle: Riders of roadsters and sports bikes were more likely to have an LOC crash greater than that of riders of basic or touring motorcycles. In addition, LOC risk increased with speed; a model using the square of the traveling speed showed better fit than one using speed itself. CONCLUSION: The LOC crash factors related to riders, vehicles, and road infrastructure identified here were expected but were rarely identified and taken simultaneously into account in previous studies. They could be targeted by countermeasures to improve motorcyclist safety.

AB - To investigate the therapeutic mechanisms underlying prostaglandin E1 (PGE1) and angiotensin-converting enzyme inhibitor (ACEI) on reducing urinary protein in diabetic kidney disease (DKD). DKD rats were established and randomly divided into four groups: PGE1 (10 MUg/kg/day) (P group), ACEI (10 mg/kg/day) (A group), combination of PGE1 with ACEI treatment (P + A group), and saline treatment group (DKD group). Untreated rats were used as normal control (N group). Urinary albumin, endothelin-1 (ET-1), angiotensin II (AngII), TUNEL assay, Masson's trichrome staining, and immunohistochemistry staining for CD68 were evaluated in all groups. Ten days after treatment, urinary albumin was significantly decreased in the P and P + A groups (p < 0.01 vs. the DKD group). At the end of 8 weeks, the albumin was still significantly reduced in the P + A group (p < 0.05 vs. the A group). ET-1 and AngII were also significantly decreased in three treatment groups (p < 0.01 vs. the DKD group), especially in the P + A group. Few cells underwent apoptosis in glomerular regions in DKD rats, while amounts of apoptotic cells were seen in tubules regions. Further, apoptosis and the areas of fibrosis in tubulointerstitial were both decreased most in the P + A group compared with the DKD group. Apoptosis of renal tubular epithelial cells may participate in the development and progression of DKD in rats. Combination of PGE1 with AGEI remarkably protects renal function compared with PGE1 or ACEI monotherapy. The potential therapeutic mechanisms of PGE1 and AGEI might be via multiple targets and, at least in part, through inhibiting the apoptosis of renal tubular epithelial cells. PMID- 29185790 TI - Sox9 Functions as a Master Regulator of Antler Growth by Controlling Multiple Cell Lineages. AB - Deer antlers are amazing natural appendages that grow faster than any other known mammalian bone. Antler growth occurs at the tip and is initially cartilage, which is later replaced by bone tissue. However, little is known regarding the precise role of cooperation between cell lineages and functional genes in regulating antler growth, and molecular mechanisms responsible for rapid growth remain elusive. In this study, we use an RNA-Seq approach to elucidate the full spectrum of cell lineages, functional genes, and their cooperative interactions during antler growth. We identify Sox9 as a pivotal transcription factor during chondrogenesis and skeletal development expressed in the chondrocyte lineage from the multipotent mesenchymal precursor stage through most subsequent cell differentiation stages with a particularly strong activity in proliferating and prehypertrophic chondrocytes. Furthermore, we analyze the miRNA expression patterns at initial growth stage and rapid growth stage and identify several miRNAs that involve in regulating antler chondrogenesis and rapid growth. Among these miRNAs, miR-140 plays pivotal role during antler growth by targeting Sox9 and vice versa. PMID- 29185791 TI - Recovery of Anthocyanins Using Membrane Technologies: A Review. AB - Anthocyanins are naturally occurring polyphenolic compounds and give many flowers, fruits and vegetable their orange, red, purple and blue colors. Besides their color attributes, anthocyanins have received much attention in recent years due to the growing evidence of their antioxidant capacity and health benefits on humans. However, these compounds usually occur in low concentrations in mixtures of complex matrices, and therefore large-scale harvesting is needed to obtain sufficient amounts for their practical usage. Effective fractionation or separation technologies are therefore essential for the screening and production of these bioactive compounds. In this context, membrane technologies have become popular due to their operational simplicity, the capacity to achieve good simultaneous separation/pre-concentration and matrix reduction with lower temperature and lower operating cost in comparison to other sample preparation methods. Membrane fractionation is based on the molecular or particle sizes (pressure-driven processes), on their charge (electrically driven processes) or are dependent on both size and charge. Other non-pressure-driven membrane processes (osmotic pressure and vapor pressure-driven) have been developed in recent years and employed as alternatives for the separation or fractionation of bioactive compounds at ambient conditions without product deterioration. These technologies are applied either individually or in combination as an integrated membrane system to meet the different requirements for the separation of bioactive compounds. The first section of this review examines the basic principles of membrane processes, including the different types of membranes, their structure, morphology and geometry. The most frequently used techniques are also discussed. Last, the specific application of these technologies for the separation, purification and concentration of phenolic compounds, with special emphasis on anthocyanins, are also provided. PMID- 29185792 TI - MetReS, an Efficient Database for Genomic Applications. AB - MetReS (Metabolic Reconstruction Server) is a genomic database that is shared between two software applications that address important biological problems. Biblio-MetReS is a data-mining tool that enables the reconstruction of molecular networks based on automated text-mining analysis of published scientific literature. Homol-MetReS allows functional (re)annotation of proteomes, to properly identify both the individual proteins involved in the processes of interest and their function. The main goal of this work was to identify the areas where the performance of the MetReS database performance could be improved and to test whether this improvement would scale to larger datasets and more complex types of analysis. The study was started with a relational database, MySQL, which is the current database server used by the applications. We also tested the performance of an alternative data-handling framework, Apache Hadoop. Hadoop is currently used for large-scale data processing. We found that this data handling framework is likely to greatly improve the efficiency of the MetReS applications as the dataset and the processing needs increase by several orders of magnitude, as expected to happen in the near future. PMID- 29185793 TI - Viability Assessment of Cryptosporidium parvum Oocysts by Vital Dyes: Dry Mounts Overestimate the Number of "Ghost" Oocysts. AB - Viability assessment of Cryptosporidium parvum oocysts is crucial for evaluation of the public health significance of this important zoonotic protozoon. Viability is commonly assessed in wet mounts after acid pretreatment and staining with fluorogenic vital dyes. However, in some studies, oocyst viability is evaluated in dry mounts after staining in suspension. Here, we evaluate the effect of acid pretreatment in nine replicate samples and compare the assessment of oocyst viability after evaluation in wet and dry mounts, respectively. Although acid pretreatment had no significant effect on the viability scores, data obtained by scoring oocysts in dry mounts resulted in ~25% underestimation of the proportion of viable oocyst (82.5% +/- 0.9% [wet mount +acid], 57.7% +/- 2.3% [dry mount, / acid], 76.0% +/- 1.7% [wet mount, / acid]), while the proportions of nonviable oocysts (DAPI+/PI+) were comparable for wet and dry mounts (9.7% +/- 0.4% [wet mount +acid], 12.1 +/- 1.5% [dry mount, / acid], 15.5% +/- 1.1% [wet mount, / acid]). PMID- 29185794 TI - The effect of correct cross-chest clip use on injury outcomes in young children during motor vehicle crashes. AB - OBJECTIVE: Traffic crashes have high mortality and morbidity for young children. Though many specialized child restraint systems improve injury outcomes, no large scale studies have investigated the cross-chest clip's role during a crash, despite concerns in some jurisdictions about the potential for neck contact injuries from the clips. This study aimed to investigate the relationship between cross-chest clip use and injury outcomes in children between 0 and 4 years of age. METHODS: Child passengers between 0 and 4 years of age were selected from the NASS-CDS data sets (2003-2014). Multiple regression analysis was used to model injury outcomes while controlling for age, crash severity, crash direction, and restraint type. The primary outcomes were overall Abbreviated Injury Score (AIS) 2+ injury, and the presence of any neck injury. RESULTS: Across all children aged 0-4 years, correct chest clip use was associated with decreased Abbreviated Injury Scale (AIS) 2+ injury (odds ratio [OR] = 0.44, 95% confidence interval [CI], 0.21-0.91) and was not associated with neck injury. However, outcomes varied by age. In children <12 months old, chest clip use was associated with decreased AIS 2+ injury (OR = 0.09, 95% CI, 0.02-0.44). Neck injury (n = 7, all AIS 1) for this age group only occurred with correct cross-chest clip use. For 1- to 4-year-old children, cross-chest clip use had no association with AIS 2+ injury, and correct use significantly decreased the odds of neck injury (OR = 0.49; 95% CI, 0.27-0.87) compared to an incorrectly used or absent cross-chest clip. No serious injuries were directly caused by the chest clips. CONCLUSIONS: Correct cross-chest clip use appeared to reduce injury in crashes, and there was no evidence of serious clip-induced injury in children in 5-point harness restraints. PMID- 29185795 TI - Curcumin against advanced glycation end products (AGEs) and AGEs-induced detrimental agents. AB - OBJECTIVES: This study was aimed to review and collate effects of curcumin on generation of advanced glycation end products (AGEs) and AGEs induced detrimental agents. METHODS: Pubmed, Googlescholar, ScienceDirect, and Scopus databases were searched. Searching was not limited to specific publication period. Only English language original articles (in vitro, experimental and human) which had examined the effect of curcumin on AGEs formation and AGEs induced apoptosis, oxidative stress or inflammatory responses were included. To review effect of curcumin on AGEs formation, search terms were as following: ''curcumin" (title) and AGEs or pentosidine or methylglyoxal or carboxymethyllysine or glucosylation (title/abstract). Totally 104 articles were searched which 19 were selected for review. To review effect of curcumin on AGEs induced harmful agents, key words were as following: "curcumin" (title) and AGEs (title/abstract) and apoptosis or oxidative stress or DNA damage or cell injury or inflammatory or cell death or cell proliferation (title/abstract). Totally 126 articles were searched which 18 were found appropriate for review. RESULTS: Regarding curcumin and AGEs formation, ten eligible articles (1 human trial, 5 animal models and 4 in vitro) and with regarding curcumin and AGEs-induced complications, 17 articles (5 on apoptosis, 9 on oxidative stress, and 3 on inflammatory responses) were selected. Except one, all studies indicated that curcumin is able to prevent AGEs formation and AGEs-induced disturbances with different potential mechanisms. CONCLUSION: Curcumin can inhibit AGEs formation and AGEs-induced disturbances. More RCT researches are suggested to evaluate beneficial effect of curcumin regarding AGEs in different age-related chronic diseases, with specific attention to AGEs memberships. PMID- 29185796 TI - Two-Dimensional Gas Chromatography Coupled With Mass Spectrometry in Food Analysis. AB - The development of instrumental analytical techniques provided the opportunity for in-depth characterization of many food matrices. In particular, the use of gas chromatography coupled with mass spectrometry gives impressive results in terms of quality and authenticity testing, conducting food freshness evaluations and contamination assessments. A new variant of gas chromatography, namely two dimensional gas chromatography (GC * GC), and various versions of mass spectrometry have been developed since last 15 years, and they still remain at the time of their renaissance. The present critical review is focused on the use of GC * GC coupled with mass spectrometry for qualitative and quantitative reasons in food analysis. It is explained how powerful analytical tool is above mentioned technical solution. Special attention is devoted to the issues related to the development of this technique during last years in terms of key construction elements, such as modulators and MS detectors. Finally, the critical discussion on many various aspects including advantages and more important disadvantages, caused probable moderate interest of this solution, in food analytics is concerned. PMID- 29185797 TI - U1 snDNA chromosomal mapping in ten spittlebug species (Cercopidade, Auchenorrhyncha, Hemiptera). AB - Spittlebugs, which belong to the family Cercopidae (Auchenorrhyncha, Hemiptera), form a large group of xylem-feeding insects that are best known for causing damage to plantations and pasture grasses. The holocentric chromosomes of these insects remain poorly studied in regards to the organization of different classes of repetitive DNA. To improve chromosomal maps based on repetitive DNAs and to better understand the chromosomal organization and evolutionary dynamics of multigene families in spittlebugs, we physically mapped the U1 snRNA gene with fluorescence in situ hybridization (FISH) in 10 species of Cercopidae belonging to three different genera. All the U1 snDNA clusters were autosomal and located in interstitial position. In seven species, they were restricted to one autosome per haploid genome, while three species of the genus Mahanarva showed two clusters in two different autosomes. Although it was not possible to precisely define the ancestral location of this gene, it was possible to observe the presence of at least one cluster located in a small bivalent in all karyotypes. The karyotype stability observed in Cercopidae is also observed in respect to the distribution of U1 snDNA. Our data are discussed in light of possible mechanisms for U1 snDNA conservation and compared with the available data from other species. PMID- 29185798 TI - Reproduction and monogamy in captive flock of greater flamingos (Phoenicopterus Roseus). AB - Due to the great number of greater flamingos in captivity and their long life span, studying their behavior and welfare might be useful to improve the husbandry and breeding of this species in zoos. This study aimed to investigate factors affecting the breeding activity of captive greater flamingos (Phoenicopterus roseus) from 2012 to 2016. To estimate reproductive success, the number of pairs, eggs laid, and hatchlings were recorded. In addition, information on age, egg-laying history of the partners, and pair composition was collected. An increase in the number of pairs, eggs, and hatchlings was reported over the years. For each breeding season, there were pairs who laid more than once, especially in 2014 and 2015. Approximately 50% of pairs were monogamous between consecutive years; however, the percentage dropped gradually when comparing nonconsecutive years. Senescence and previous experience seemed to affect the reproductive success of the study flamingos. In conclusion, different factors can influence the reproduction of greater flamingos in zoos. All these factors are related to nonhuman animal welfare and need to be considered in developing and improving management practices. PMID- 29185799 TI - Social inequality in phase II cardiac rehabilitation attendance: The impact of potential mediators. AB - BACKGROUND: Cardiac rehabilitation participation is an essential component of the contemporary management of coronary heart disease. However, patients with low socioeconomic position are less likely to attend the rehabilitation programme. AIM: We aimed to explore the effect of potential mediators between socioeconomic position defined by educational attainment and cardiac rehabilitation attendance. METHODS: Prospective observational study of patients with acute coronary syndrome ( N=302). Logistic regression and mediation analysis was conducted to explore mechanisms of non-attendance. RESULTS: Thirty per cent attended full cardiac rehabilitation. Patients with low educational attainment, comorbidities, long commute to cardiac rehabilitation centre, and lone dwelling were less likely to attend full cardiac rehabilitation, whereas patients with high anxiety and depression score were more likely to attend full cardiac rehabilitation. Patients with low educational attainment had lower self-efficacy and longer commute compared with patients with high educational attainment. The potential mediators included in the study, however, did not have a significant mediation effect. CONCLUSION: Our study demonstrated a variety of mechanisms contributing to cardiac rehabilitation non-attendance. Further, the study demonstrated that non attendance was especially related to the cardiac rehabilitation elements involving lifestyle modifications. However, the mechanisms explaining social inequality in full cardiac rehabilitation are still not fully understood. PMID- 29185800 TI - Eight Novel Mutations of the ADAR1 Gene in Chinese Patients with Dyschromatosis Symmetrica Hereditaria. AB - AIMS: To identify potential novel gene mutations in Chinese patients with dyschromatosis symmetrica hereditaria (DSH). METHODS: We enrolled 8 Chinese patients with familial DSH, 5 Chinese patients with sporadic DSH, and 100 randomly selected healthy individuals in this study. The genome of each participant was extracted from peripheral blood samples. Sanger sequencing of the ADAR1 gene was performed after polymerase chain reaction amplifications. Comparisons between the DNA sequences of the affected individuals and the NCBI database were performed. RESULTS: We detected eight novel heterozygous mutations and five previously reported mutations in the ADAR1 gene in our patients. The novel mutations include c.1934 + 3A>G, c.2749A>G, c.2311insA, c.3233G>A, c.3019 + 1G>T, c.2894C>A, c.1202_1205del, and c.2280C>A. These detected novel mutations are predicted to induce two frame-shift mutations, one nonsense mutation, three missense mutations, and two splice-site mutations. CONCLUSIONS: The findings of this study expand our knowledge of the range of ADAR1 gene mutations in DSH and will contribute to identifying correlations between the various DSH phenotypes and genotypes. Furthermore, they may provide insight into the underlying pathogenic mechanism. PMID- 29185801 TI - The Pre-Exposure Prophylaxis-Stigma Paradox: Learning from Canada's First Wave of PrEP Users. AB - With the emergence of daily oral tenofovir disoproxil fumarate and emtricitabine based pre-exposure prophylaxis (PrEP) use in Canada, questions have emerged concerning the impacts of this HIV prevention tool on gay men's social and sexual lives. We conducted small focus groups and individual qualitative interviews with 16 gay men in Toronto who were part of the 'first wave' of Canadian PrEP users. Participants were on PrEP for at least one year as part of a demonstration project (November 2014-June 2016). These participants accessed PrEP before regulatory approval by Health Canada in February 2016. The mean age of participants was 37.6 years (SD 11.02); 94% completed secondary education, and 69% were white. Sex-stigma emerged as a complex theme in men's accounts of PrEP use across three overlapping domains: (1) PrEP-related stigma, including discussions of concealment and stigma from friends, family, and sexual partners, (2) PrEP as a perceived tool for combating HIV-related stigma, where some men said that they no longer discussed HIV status with sexual partners, and (3) PrEP as illuminating structural stigma, where it was attributed to unmasking stigma related to sex and sexuality. For some participants, PrEP has allowed for liberating sex and a self-described return to normalcy-normal, exciting, pleasurable sex that was no longer reliant on condom use. Paradoxically, some men said that PrEP use both led them to experience stigmatizing reactions within their social and sexual networks, while also helping to remove stigma, shame, and fear related to HIV, sexuality, and sex with gay men living with HIV. PMID- 29185802 TI - Effects of Cupping Therapy in Amateur and Professional Athletes: Systematic Review of Randomized Controlled Trials. AB - OBJECTIVE: Despite the recent re-emergence of the process of cupping by athletes, supporting evidence for its efficacy and safety remains scarce. This systematic review aims to summarize the evidence of clinical trials on cupping for athletes. METHODS: SCOPUS, Cochrane Library, PubMed, AMED, and CNKI databases were searched from their inception to December 10, 2016. Randomized controlled trials on cupping therapy with no restriction regarding the technique, or cointerventions, were included, if they measured the effects of cupping compared with any other intervention on health and performance outcomes in professionals, semi professionals, and leisure athletes. Data extraction and risk of bias assessment using the Cochrane Risk of Bias Tool were conducted independently by two pairs of reviewers. RESULTS: Eleven trials with n = 498 participants from China, the United States, Greece, Iran, and the United Arab Emirates were included, reporting effects on different populations, including soccer, football, and handball players, swimmers, gymnasts, and track and field athletes of both amateur and professional nature. Cupping was applied between 1 and 20 times, in daily or weekly intervals, alone or in combination with, for example, acupuncture. Outcomes varied greatly from symptom intensity, recovery measures, functional measures, serum markers, and experimental outcomes. Cupping was reported as beneficial for perceptions of pain and disability, increased range of motion, and reductions in creatine kinase when compared to mostly untreated control groups. The majority of trials had an unclear or high risk of bias. None of the studies reported safety. CONCLUSIONS: No explicit recommendation for or against the use of cupping for athletes can be made. More studies are necessary for conclusive judgment on the efficacy and safety of cupping in athletes.

AB - The brain undergoes functional dynamic changes at all times. Investigating functional dynamics has been recently verified to be helpful for detecting psychological conditions and powerful for analyzing disease-related abnormalities of the brain. This article aims to detect functional dynamics. Specifically, we focus on how to effectively distinguish corresponding functional connectivity and change points from functional magnetic resonance imaging (fMRI) data. By combining Bayesian connectivity change point model (BCCPM), a modified genetic algorithm (GA) is presented to optimize the evolutionary procedure toward the most probable distributions of real change points in fMRI. We randomly initialize different binary indicator vectors to represent different distributions of change points. Each indicator vector represents an individual in GA, and together they form an initial population. Then we calculate Bayesian posterior probability and use it as the fitness of each individual. Finally, we evolve individuals of current generation toward the next higher fitness generation by a series of modified genetic operators. After several evolutionary procedures, individuals in the final generation may have outstanding fitness and the one with highest fitness can represent the most likely change point distribution in the corresponding fMRI data. Furthermore, the most probable change point distribution could be resolved. We test the optimized method for BCCPM on several synthesized data sets, and the experimental results verify that the proposed model produces higher accuracy results with lower time consumption. Also, we apply the new model to real block-designed task-based fMRI data set and excellent results are obtained. PMID- 29185807 TI - ICON-MIC: Implementing a CPU/MIC Collaboration Parallel Framework for ICON on Tianhe-2 Supercomputer. AB - Electron tomography (ET) is an important technique for studying the three dimensional structures of the biological ultrastructure. Recently, ET has reached sub-nanometer resolution for investigating the native and conformational dynamics of macromolecular complexes by combining with the sub-tomogram averaging approach. Due to the limited sampling angles, ET reconstruction typically suffers from the "missing wedge" problem. Using a validation procedure, iterative compressed-sensing optimized nonuniform fast Fourier transform (NUFFT) reconstruction (ICON) demonstrates its power in restoring validated missing information for a low-signal-to-noise ratio biological ET dataset. However, the huge computational demand has become a bottleneck for the application of ICON. In this work, we implemented a parallel acceleration technology ICON-many integrated core (MIC) on Xeon Phi cards to address the huge computational demand of ICON. During this step, we parallelize the element-wise matrix operations and use the efficient summation of a matrix to reduce the cost of matrix computation. We also developed parallel versions of NUFFT on MIC to achieve a high acceleration of ICON by using more efficient fast Fourier transform (FFT) calculation. We then proposed a hybrid task allocation strategy (two-level load balancing) to improve the overall performance of ICON-MIC by making full use of the idle resources on Tianhe-2 supercomputer. Experimental results using two different datasets show that ICON-MIC has high accuracy in biological specimens under different noise levels and a significant acceleration, up to 13.3 * , compared with the CPU version. Further, ICON-MIC has good scalability efficiency and overall performance on Tianhe-2 supercomputer. PMID- 29185806 TI - Workplace Breastfeeding Support Varies by Employment Type: The Service Workplace Disadvantage. AB - BACKGROUND: The majority of women are returning to work full-time after childbirth, and support within their place of employment may influence intention and duration for breastfeeding, but more research is needed. Therefore, the purpose of this study was to explore the influence of employment type on breastfeeding duration upon return to work by examining informal (i.e., verbal encouragement) and direct (i.e., lactation space, flexible time) factors of support. METHODS: This was a retrospective survey of women's returning-to-work experiences while breastfeeding. Survey contents included respondent demographics as well as questions surrounding perceptions of employer support, work environment, and goal/satisfaction regarding breastfeeding. Data were analyzed via crosstabs and chi-square goodness of fit tests. RESULTS: A total of 1,002 women completed the survey. Significant differences were seen across different employment types. Women within the professional/management industry were most likely to receive informal and direct support for breastfeeding upon return to work. Women within the service industry and production/transportation industry reported receiving the lowest levels of informal and direct support. CONCLUSION: Workplace support varies by employment type and women in the service and production/transportation industry appear to be at a disadvantage compared with other employment types. There is a need for more breastfeeding support programs to be developed that target specific workplace characteristics. PMID- 29185808 TI - Lipid-modifying activity of curcuminoids: A systematic review and meta-analysis of randomized controlled trials. AB - OBJECTIVE: The aim of this systematic review and meta-analysis was to determine and clarify the impact of curcuminoids on serum lipid levels. METHODS: Randomized controlled trials (RCTs) investigating the effects of curcuminoids on plasma lipids were searched in PubMed-Medline, Scopus, Web of Science databases (from inception to April 3rd, 2017). A random-effects model and generic inverse variance method were used for quantitative data synthesis. Sensitivity analysis was conducted using the leave-one-out method. A weighted random-effects meta regression was performed to evaluate the impact of potential confounders on lipid concentrations. RESULTS: A meta-analysis of 20 RCTs with 1427 participants suggested a significant decrease in plasma concentrations of triglycerides (WMD: 21.36 mg/dL, 95% CI: -32.18, -10.53, p < 0.001), and an elevation in plasma HDL-C levels (WMD: 1.42 mg/dL, 95% CI: 0.03, 2.81, p = 0.046), while plasma levels of LDL-C (WMD: -5.82 mg/dL, 95% CI: -15.80, 4.16, p = 0.253) and total cholesterol (WMD: -9.57 mg/dL, 95% CI: -20.89, 1.75, p = 0.098) were not altered. The effects of curcuminoids on lipids were not found to be dependent on the duration of supplementation. CONCLUSION: This meta-analysis has shown that curcuminoid therapy significantly reduces plasma triglycerides and increases HDL-C levels. PMID- 29185809 TI - Spatial memory recovery in Alzheimer's rat model by electromagnetic field exposure. AB - INTRODUCTION: Although studies have shown a potential association between extremely low frequency electromagnetic fields (ELF-EMFs) exposure and Alzheimer's disease (AD), few studies have been conducted to investigate the effects of weak magnetic fields on brain functions such as cognitive functions in animal models. Therefore, this study aimed to investigate the effect of ELF-EMF exposure (50 Hz, 10 mT) on spatial learning and memory changes in AD rats. METHODS: Amyloid-beta (Abeta) 1-42 was injected into lateral ventricle to establish an AD rat model. The rats were divided into six groups: Group I (control); Group II (surgical sham); Group III (AD) Alzheimer's rat model; Group IV (MF) rats exposed to ELF-MF for 14 consecutive days; Group V (Abeta injection+M) rats exposed to magnetic field for 14 consecutive days from day 0 to 14 days after the Abeta peptide injection; Group VI (AD+M) rats exposed to magnetic field for 14 consecutive days after 2 weeks of Abeta peptide injection from 14th to 28th day . Morris water maze investigations were performed. RESULTS: AD rats showed a significant impairment in learning and memory compared to control rats. The results showed that ELF-MF improved the learning and memory impairments in Abeta injection+M and AD+M groups. CONCLUSION: Our results showed that application of ELF-MF not only has improving effect on different cognitive disorder signs of AD animals, but also disrupts the processes of AD rat model formation. PMID- 29185810 TI - Investigation Into the Optimal Number of Intercostal Nerve Transfers for Musculocutaneous Nerve Reinnervation: A Systematic Review. AB - BACKGROUND: The purpose of this study was to systematically review outcomes following intercostal nerve (ICN) transfer for restoration of elbow flexion, with a focus on identifying the optimal number of nerve transfers. METHODS: A systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines to identify studies describing ICN transfers to the musculocutaneous nerve (MCN) for traumatic brachial plexus injuries in patients 16 years or older. Demographics were recorded, including age, time to operation, and level of brachial plexus injury. Muscle strength was scored based upon the British Medical Research Council scale. RESULTS: Twelve studies met inclusion criteria for a total of 196 patients. Either 2 (n = 113), 3 (n = 69), or 4 (n = 11) ICNs were transferred to the MCN in each patient. The groups were similar with regard to patient demographics. Elbow flexion >=M3 was achieved in 71.3% (95% confidence interval [CI], 61.1%-79.7%) of patients with 2 ICNs, 67.7% (95% CI, 55.3%-78.0%) of patients with 3 ICNs, and 77.0% (95% CI, 44.9%-93.2%) of patients with 4 ICNs ( P = .79). Elbow flexion >=M4 was achieved in 51.1% (95% CI, 37.4%-64.6%) of patients with 2 ICNs, 42.1% (95% CI, 29.5%-55.9%) of patients with 3 ICNs, and 48.4% (95% CI, 19.2%-78.8%) of patients with 4 ICNs ( P = .66). CONCLUSIONS: Previous reports have described 2.5 times increased morbidity with each additional ICN harvest. Based on the equivalent strength of elbow flexion irrespective of the number of nerves transferred, 2 ICNs are recommended to the MCN to avoid further donor-site morbidity.

AB - Illegal harvesting and trade are major forces behind population declines of wild slow lorises (genus Nycticebus). The impacts of the wildlife trade on individual slow lorises have not been as well described. In this article, we describe quantitatively the consequences of the wildlife trade for 77 greater slow lorises, N. coucang, who were confiscated en masse and brought to Cikananga Wildlife Center in Indonesia. Medical records indicated that in total, 28.6% of the slow lorises died within the first 6 months, mostly due to traumatic injury, and all the infants died. The greatest sources of morbidity were external wounds (33.1% of 166 total medical events) and dental problems (19.3%). Of the surviving individuals, 25.4% displayed abnormal behavior. Behavioral observations indicated that healthy adults (n = 3) spent 48.2% of their active period performing stereotypies. These data illustrate the physical and behavioral impacts of the illegal wildlife trade on the welfare of slow lorises. We suggest that sharing these individual stories may help generate empathy and educate the public about the impacts of the exotic companion-animal (pet) trade on nonhuman animal welfare. PMID- 29185813 TI - The Trapezium Dislocation: Case Presentation, Review of the Literature, Radiographic Analysis, Proposed Classification, and Treatment. AB - BACKGROUND: Trapezium dislocations are rare injuries. METHODS: A PubMed search of the term "trapezium dislocation" was conducted. Publications reporting a complete trapezium dislocation were included in the review. RESULTS: The PubMed search resulted in 168 results. Fourteen publications reporting on 16 complete trapezium dislocations met inclusion criteria. A case of delayed diagnosis of a trapezium dislocation is presented. The literature is reviewed for pertinent clinically relevant information with respect to trapezium dislocations. A systematic method for radiographic analysis of trapezium dislocations and classification are described, and a treatment algorithm is presented. CONCLUSIONS: Trapezium dislocations are infrequent injuries with few cases reported in the literature. Given the rarity of this injury, diagnosis and appropriate treatment may be delayed due to difficulty in recognition. Using the described method of radiographic analysis, delayed diagnosis may be avoided with implementation of timely treatment. PMID- 29185812 TI - Brand and generic use of inhalation medication and frequency of switching in children and adults: A population-based cohort study. AB - BACKGROUND: The expiration of patents of brand inhalation medications and the ongoing pressure on healthcare budgets resulted in a growing market for generics. AIM: To study the use of brand and generic inhalation medication and the frequency of switching between brand and generic and between devices. In addition, we investigated whether switching affected adherence. METHODS: From dispensing data from the Dutch PHARMO Database Network a cohort aged >= 5 years, using >= 1 year of inhalation medication between 2003 and 2012 was selected. Switching was defined as changing from brand to generic or vice versa. In addition, we studied change in aerosol delivery device type (e.g., DPI, pMDI, and nebulizers). Adherence was calculated using the medication possession ratio (MPR). RESULTS: The total cohort comprised 70,053 patients with 1,604,488 dispensations. Per calendar year, 5% switched between brand and generic inhalation medication and 5% switched between devices. Median MPRs over the first 12 months ranged between 33 and 55%. Median MPR over the total period was lower after switch from brand to generic and vice versa for formoterol (44.5 vs. 42.1 and 63.5 vs. 53.8) and beclomethasone (93.8 vs. 59.8 and 81.3 vs. 55.9). CONCLUSION: Per year, switching between brand and generic inhalation medication was limited to 5% of the patients, switching between device types was observed in 5% as well. Adherence to both generic and brand inhalation medication was low. Effect of switching on adherence was contradictory; depending on time period, medication and type, and direction of switching. Further research on reasons for switching and potential impact on clinical outcomes is warranted. PMID- 29185814 TI - Pupil Dilation May Affect Retinal Vessel Caliber Measures. AB - PURPOSE: To assess the effect of pupil dilation on measures of retinal vessel caliber. DESIGN: Observational study with self-comparisons Methods: Retinal photographs were taken for both eyes of 25 subjects before and after pupil dilation. Three photographic graders, masked to pupil dilation status, measured the same set of images using a computer-assisted, semi-automatic method. We compared means (standard deviations) of retinal arteriolar caliber equivalent (CRAE) and retinal venular caliber equivalent (CRVE) of the same eyes between pre and post-dilation images. We assessed concordance correlation coefficients (CC), Bland Altman limits-of-agreements, and used linear mixed models to assess CRAE and CRVE measures associated with pupil dilation (influencing image quality), graders (observers) and right-left eye variation. RESULTS: We found high CCs for CRAE (0.82-0.94) and CRVE (0.87-0.94) between pre- and post-dilation images of the same eyes across the graders. Bland Altman plots showed that mean differences ranged from 0.55-3.42MUm for CRAE and 1.56-2.29MUm for CRVE. After adjusting for right-left eye random variation, a significant fixed effect of dilation was evident in mean CRAE in two of the three graders. There was no significant fixed effect of dilation in mean CRVE across all graders. In models including data of both eyes' measures from pre- and post-dilation images by three graders, the fixed effect for dilation status contributed significantly to CRAE and CRVE variances whereas random effects for graders and dilation status contributed minimally. CONCLUSIONS: Contrary to our hypothesis, we found a systematic effect of pupil dilation on retinal vessel caliber measures. PMID- 29185815 TI - 2016 Annual Report of the American Association of Poison Control Centers' National Poison Data System (NPDS): 34th Annual Report. AB - INTRODUCTION: This is the 34th Annual Report of the American Association of Poison Control Centers' (AAPCC) National Poison Data System (NPDS). As of 1 January 2016, 55 of the nation's poison centers (PCs) uploaded case data automatically to NPDS. The upload interval was 9.50 [7.33, 14.6] (median [25%, 75%]) min, facilitating a near real-time national exposure and information database and surveillance system. METHODS: We analyzed the case data tabulating specific indices from NPDS. The methodology was similar to that of previous years. Where changes were introduced, the differences are identified. Cases with medical outcomes of death were evaluated by a team of medical and clinical toxicologist reviewers using an ordinal scale of 1-6 to assess the Relative Contribution to Fatality (RCF) of the exposure. RESULTS: In 2016, 2,710,042 closed encounters were logged by NPDS: 2,159,032 human exposures, 54,019 animal exposures, 490,215 information cases, 6687 human confirmed non-exposures, and 89 animal confirmed non-exposures. US PCs also made 2,718,022 follow-up calls in 2016. Total encounters showed a 2.94% decline from 2015, while health care facility (HCF) human exposure cases increased by 3.63% from 2015. All information calls decreased by 12.5% but HCF information calls increased 0.454%, and while medication identification requests (Drug ID) decreased 29.6%, human exposure cases were essentially flat, decreasing by 0.431%. Human exposures with less serious outcomes have decreased 2.59% per year since 2008 while those with more serious outcomes (moderate, major or death) have increased by 4.39% per year since 2000. The top five substance classes most frequently involved in all human exposures were analgesics (11.2%), household cleaning substances (7.54%), cosmetics/personal care products (7.20%), sedatives/hypnotics/antipsychotics (5.84%), and antidepressants (4.74%). As a class, sedative/hypnotics/antipsychotics exposures increased most rapidly, by 10.7% per year (2088 cases/year), over the last 15 years for cases showing more serious outcomes. The top five most common exposures in children age 5 years or less were cosmetics/personal care products (13.3%), household cleaning substances (11.1%), analgesics (9.21%), foreign bodies/toys/miscellaneous (6.48%), and topical preparations (5.07%). Drug identification requests comprised 28.1% of all information calls. NPDS documented 1977 human exposures resulting in death; 1492 (75.5%) of these were judged as related (RCF of 1 - undoubtedly responsible, 2 - probably responsible, or 3 - contributory). CONCLUSIONS: These data support the continued value of PC expertise and need for specialized medical toxicology information to manage more serious exposures, despite a decrease in cases involving less serious exposures. Unintentional and intentional exposures continue to be a significant cause of morbidity and mortality in the US. The near real-time, always current status of NPDS represents a national public health resource for collecting and monitoring US exposure cases and information calls. The continuing mission of NPDS is to provide a nationwide infrastructure for surveillance for all types of exposures (e.g. foreign body, infectious, venomous, chemical agent, or commercial product), and the identification and tracking of significant public health events. NPDS is a model system for the real-time surveillance of national and global public health. PMID- 29185817 TI - Does Religious Attendance Moderate the Connection between Pornography Consumption and Attitudes toward Women? AB - Feminist theory and religious doctrines alike often suggest that pornography alters the attitudes of those who consume it, particularly with respect to how consumers view women. Many would assume that pornography would universally encourage sexism and female objectification, but recent evidence has linked pornography use with more gender egalitarian views. Using data from a large scale, nationally representative survey, we argue that cognitive dissonance among pornography consumers could alter egalitarian attitudes. We found that those who reported consuming pornography had more egalitarian attitudes than those who did not, but this difference was stronger among those who attended religious services more regularly-those who would be likely to experience dissonance when consuming pornography. This pattern was consistent across the three egalitarian attitudes we examined: attitudes toward women in power, women in the workplace, and abortion. Our results suggest that pornography might foster progressive attitudes among those most likely to hold conservative beliefs. PMID- 29185816 TI - Measurements of Retinal Nerve Fiber Thickness and Ganglion Cell Complex in Neurofibromatosis Type 1, with and Without Optic Pathway Gliomas: A Case Series. AB - PURPOSE: The aim of this study was to investigate differences in retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) thicknesses in neurofibromatosis 1 (NF1) cases, with and without optic pathway gliomas (OPGs). MATERIALS AND METHODS: In total, 33 eyes of 33 subjects were evaluated in this prospective observational case series. Twenty-one patients with a diagnosis of NF1 were enrolled. Patients with NF1 and OPGs were included in Group 1 (n = 9), and patients with NF1 without OPGs were included in Group 2 (n = 12). The control group (Group 3) was comprised of 12 age- and sex-matched subjects with no history of ophthalmic or systemic diseases. All of the subjects underwent complete ophthalmic examinations, including best-corrected visual acuity (BCVA), slit lamp microscopy, and indirect ophthalmoscopy. Additionally, optical coherence tomography (OCT) measurements were obtained. RESULTS: There were no statistically significant between-group differences in age and sex (p = 0.227 and 0.986, respectively). The average RNFL thickness in Group 1 (NF1 patients with OPGs) was significantly lower than in Groups 2 and 3 (86.6 +/- 22.5, 107.4 +/- 6.65, and 108.4 +/- 5.05 um, respectively; p = 0.001). Furthermore, the average GCC thickness in Group 1 was significantly lower than in Groups 2 and 3 (78.6 +/- 16.3, 94.8 +/- 3.55, and 94.9 +/- 3.82 um, respectively; p < 0.001). CONCLUSIONS: Both RNFL and GCC thicknesses were significantly lower in NF1 patients with OPGs. The use of OCT to quantify damage to the visual pathway may enable earlier detection of OPGs in NF1 patients. PMID- 29185818 TI - Teaming With a Synthetic Teammate: Insights into Human-Autonomy Teaming. AB - Objective Three different team configurations are compared with the goal of better understanding human-autonomy teaming (HAT). Background Although an extensive literature on human-automation interaction exists, much less is known about HAT in which humans and autonomous agents interact as coordinated units. Further research must be conducted to better understand how all-human teams compare to HAT. Methods In an unmanned aerial system (UAS) context, a comparison was made among three types of three-member teams: (1) synthetic teams in which the pilot role is assigned to a synthetic teammate, (2) control teams in which the pilot was an inexperienced human, and (3) experimenter teams in which an experimenter served as an experienced pilot. Ten of each type of team participated. Measures of team performance, target processing efficiency, team situation awareness, and team verbal behaviors were analyzed. Results Synthetic teams performed as well at the mission level as control (all human) teams but processed targets less efficiently. Experimenter teams performed better across all other measures compared to control and synthetic teams. Conclusion Though there is potential for a synthetic agent to function as a full-fledged teammate, further advances in autonomy are needed to improve team-level dynamics in HAT teams. Application This research contributes to our understanding of how to make autonomy a good team player. PMID- 29185819 TI - Reversal of Glanzmann thrombasthenia platelet phenotype after imatinib treatment in a pediatric chronic myeloid leukemia patient. AB - Chronic Myelogenous Leukemia (CML) is a myeloproliferative neoplasm characterized by proliferation of Philadelphia positive clonal pluripotent hematopoietic cells. Bleeding is a rare presentation of CML that can occur due to platelet dysfunction. Both pre-treatment and post-treatment platelet function abnormalities in CML have been described in the literature. We describe a rare case of childhood CML who presented with mucocutateous bleeding manifestations. On laboratory workup, a Glanzmann Thrombasthenia (GT) like platelet phenotype was demonstrated along with confirmation of diagnosis of CML in chronic phase. The acquired nature of platelet function defect was confirmed by demonstrating recovery of platelet antigens glycoprotein IIb/IIIa after achieving complete hematological response with Imatinib. Due to presenting complaint of bleeding diathesis and absence of hepatosplenomegaly, the case was undiagnosed for CML until the patient reported to us. Careful evaluation of complete blood counts, peripheral blood picture and detailed laboratory workup was the window to proper diagnosis and treatment in this case. PMID- 29185820 TI - Delusional misidentification in Parkinson's disease: report of two cases and a review. AB - Syndromes of delusional misidentification consist of disordered familiarity and have been reported in diverse diagnoses, including Parkinson's disease. Although the most common delusional misidentification is Capgras syndrome, in which the sufferer believes a familiar person has been replaced by an identical imposter, other forms have been also described. The pathogenesis of delusions of misidentification appears to require dysfunction of or connection to a left cerebral cortical area involved in recognition of familiarity, and also right frontal cortex serving belief evaluation. Two cases of Parkinson's disease with an unusual delusional misidentification, intermetamorphosis, are presented, along with their improvement with pimavanserin, a novel atypical antipsychotic medication. PMID- 29185821 TI - Neurocognitive and neurodevelopmental impact of prenatal methamphetamine exposure: A comparison study of prenatally exposed children with nonexposed ADHD peers. AB - Prenatal methamphetamine exposure has become an increasingly pervasive concern, especially in rural-based populations and populations of lower socioeconomic status. While research has begun to highlight the effects of prenatal methamphetamine exposure, the long-term impact of this exposure remains an under investigated topic. This study attempts to investigate the neurocognitive and neurodevelopmental effects of prenatal methamphetamine exposure by comparing the index and full-scale IQ scores on the WISC-IV between a sample of clinically referred children prenatally exposed to methamphetamine (N = 80) and a sample of clinically referred nonexposed children diagnosed with ADHD (N = 44). Children prenatally exposed to methamphetamine showed significantly lower scores on all WISC-IV domains when compared to peers with ADHD. When taking into account polysubstance exposure to alcohol, these differences remained statistically significant, with the exception of the Processing Speed Index (PSI); children reported to have been prenatally exposed to methamphetamine and to alcohol (PME) remained below ADHD peers on all other WISC-IV index scores. Within the prenatally exposed sample, regression analyses indicated that age was a significant negative predictor of PSI scores. Overall findings suggest that prenatal methamphetamine exposure is associated with a notable cognitive impact independent of polysubstance exposure to alcohol, and that the impact of this exposure on processing speed skills may become more pronounced with age. PMID- 29185822 TI - Safety and efficacy of ipragliflozin in Japanese patients with type 2 diabetes in real-world clinical practice: interim results of the STELLA-LONG TERM post marketing surveillance study. AB - BACKGROUND: Data regarding the efficacy and safety of sodium-glucose cotransporter 2 inhibitors in the real-world setting in Japan are limited. The STELLA-LONG TERM study is an ongoing 3-year post-marketing surveillance study of ipragliflozin in type 2 diabetes (T2D) patients. Here, we report the interim results (including 3-, 12-, and 24-month data). RESEARCH DESIGN AND METHODS: All Japanese patients with T2D who were first prescribed ipragliflozin between 17 July 2014 and 16 October 2015 at participating centers in Japan were registered in STELLA-LONG TERM. RESULTS: At 3, 12, and 24 months, the safety analysis set comprised 11,053, 5475, and 138 patients, respectively; the efficacy analysis set comprised 8757 patients. Ipragliflozin treatment resulted in statistically significant improvements versus baseline in hemoglobin A1c, fasting plasma glucose concentration, body weight, blood pressure, heart rate, and serum concentrations of low-density lipoprotein cholesterol and triglycerides. The adverse drug reaction incidence rate was 10.71%, the most common reactions being renal and urinary disorders (5.06%), infections and infestations (1.24%), and skin and subcutaneous tissue disorders (1.14%). CONCLUSIONS: Ipragliflozin was well tolerated and effective in Japanese patients with T2D; no new safety issues were identified. PMID- 29185823 TI - Texas Mexican American adult normative studies: Normative data for the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). AB - The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is an assessment of neuropsychological functioning commonly used in clinical and research settings. To our knowledge, normative data for the RBANS is not available for Hispanic, Mexican Americans, which the current study sought to establish. Data from 136 Hispanic, Mexican Americans from Project FRONTIER were analyzed. Approximately half of the sample was administered testing in Spanish. Normative tables were created for English and Spanish speaking Mexican Americans. Generated RBANS normative references are provided for unadjusted raw scores as well as output adjusted by education level. PMID- 29185824 TI - Comparison Between High-Pressure Processing and Chemical Extraction: Astaxanthin Yield From Six Species of Shrimp Carapace. AB - Astaxanthin is one of the main carotenoid pigments. It has beneficial effects on the immune system of the human body due to its powerful antioxidant properties. The application of this bioactive compound can be found to be significant in the food, pharmaceutical, and cosmetics industries. The aim of this research was to investigate astaxanthin yield from six species of Malaysian shrimp carapace. Six types of shrimp species-Parapenaeopsis sculptili, Metapenaeus lysianassa, Macrobrachium rosenbergii, Metapenaeopsis hardwickii, Penaeus merguiensis, and Penaeus monodon-were used to investigate total carotenoid content and astaxanthin yield. The investigation was carried out using chemical extraction and high pressure processing (HPP) methods at 210 MPa, for a period of 10 min with a solvent mixture of acetone and methanol (7:3, v/v). HPP was proven to have a significant impact in increasing the total carotenoid content and astaxanthin yield. The highest total carotenoid content and astaxanthin yield is shown to be contained in the Penaeus monodon species. Total carotenoid was increased from 46.95 ug/ml using chemical extraction to 68.26 ug/ml using HPP; yield of astaxanthin was increased from 29.44 ug/gdw using chemical extraction to 59.9744 ug/gdw using HPP. Therefore, comparison between the HPP and chemical extraction methods showed that HPP is more advantageous with higher astaxanthin yield, higher quality, and shorter extraction time. PMID- 29185825 TI - Effect of Probiotic Supplementation on CD4 Cell Count in HIV-Infected Patients: A Systematic Review and Meta-analysis. AB - Progressive decline in CD4 cell counts is associated with human immunodeficiency virus (HIV) disease progression. Loss of CD4 cells might contribute to gut microbiota alteration and bacterial translocation. Probiotics, by inducing epithelial healing, may promote the restoration of the intestinal CD4+ T-cell population. The aim of this meta-analysis was to systematically review all randomized controlled trials (RCTs) of probiotic/prebiotic/synbiotic supplementation on CD4 cell counts in HIV-infected patients. A systematic search of RCTs was conducted through PubMed, Scopus, and Google Scholar databases up to August 2015. Effect sizes of eligible studies were pooled using random-effects models (the DerSimonian-Laird estimator). Eleven studies with 14 treatment arms met the inclusion criteria. Pooled analysis showed no significant reduction in CD4 counts (-7.5 mg/l, p = .7) in intervention-treated individuals. Subgroup analysis on potential influencing factors highlighted sex, country of origin, study duration, and the type of intervention as having significant effects on CD4 cell counts. As a whole, the results of this meta-analysis suggested that supplementation with probiotic may not change CD4 counts. However, a significant increase in CD4 counts was seen in females and following synbiotics as opposed to treatment with pro- or prebiotics alone. PMID- 29185826 TI - Series: Practical guidance to qualitative research. Part 2: Context, research questions and designs. AB - In the course of our supervisory work over the years, we have noticed that qualitative research tends to evoke a lot of questions and worries, so-called frequently asked questions (FAQs). This series of four articles intends to provide novice researchers with practical guidance for conducting high-quality qualitative research in primary care. By 'novice' we mean Master's students and junior researchers, as well as experienced quantitative researchers who are engaging in qualitative research for the first time. This series addresses their questions and provides researchers, readers, reviewers and editors with references to criteria and tools for judging the quality of qualitative research papers. This second article addresses FAQs about context, research questions and designs. Qualitative research takes into account the natural contexts in which individuals or groups function to provide an in-depth understanding of real-world problems. The research questions are generally broad and open to unexpected findings. The choice of a qualitative design primarily depends on the nature of the research problem, the research question(s) and the scientific knowledge one seeks. Ethnography, phenomenology and grounded theory are considered to represent the 'big three' qualitative approaches. Theory guides the researcher through the research process by providing a 'lens' to look at the phenomenon under study. Since qualitative researchers and the participants of their studies interact in a social process, researchers influence the research process. The first article described the key features of qualitative research, the third article will focus on sampling, data collection and analysis, while the last article focuses on trustworthiness and publishing. PMID- 29185827 TI - Eugenics, medicine and psychiatry in Peru. AB - Eugenics was defined by Galton as 'the science which deals with all influences that improve the inborn qualities of a race'. In Peru, eugenics was related to social medicine and mental hygiene, in accordance with the neo-Lamarckian orientation, that predominated in Latin America. Peruvian eugenists assumed the mission of fighting hereditary and infectious diseases, malnutrition, alcoholism, drug addiction, prostitution, criminality and everything that threatened the future of the 'Peruvian race'. There were some enthusiastic advocates of 'hard' eugenic measures, such as forced sterilization and eugenic abortion, but these were never officially implemented in Peru (except for the compulsory sterilization campaign during the 1995-2000 period). Eugenics dominated scientific discourse during the first half of the twentieth century, but eugenic discourse did not disappear completely until the 1970s. PMID- 29185828 TI - Increased prevalence of depression and anxiety among subjects with metabolic syndrome and known type 2 diabetes mellitus - a population-based study. AB - OBJECTIVES: The metabolic syndrome (MetS) is a cluster of cardiovascular risk factors associated with high cardiovascular morbidity and mortality. The MetS and its elements have been linked to anxiety and depressive disorders. The aim of the current cross-sectional study was to assess the prevalence of depression and anxiety, measured by the Zung Self-Rating Scale in subjects with and without the metabolic syndrome and diabetes. METHODS: A total of 2111 adults were included, 1155 female, age 47.6 (13.7) and 956 male, age 45.2 (13.5). All participants filled questionnaires covering current and past disorders and medication, smoking and family history. Zung self-rating depression and anxiety scales were completed. Body weight, height and waist circumference were measured, BMI was calculated, serum glucose and lipids were measured. RESULTS: Depression (SDSi) and anxiety scores (SASi) were higher in the females and increased with age (p < 0.001). SDSi was higher in the females and males with metabolic syndrome (MetS) (50.9 +/- 9.8 vs. 45.9 +/- 8.9, p < 0.001 and 42.7 +/- 9.2 vs. 40.5 +/- 7.9 p < 0.001, respectively). SASi was higher in the MetS subjects (females 50.59 +/- 11.35 vs. 45.97 +/- 10.58, p < 0.001; males 40.48 +/- 10.1 vs. 38.04 +/- 8.42, p < 0.001). Both SDSi and SASi were higher in the subjects with known diabetes than in those with normal glucose tolerance (Mann-Whitney both p < 0,001). Positive depressive scores were more prevalent in subjects with MetS than those without (females 54% vs. 31.6%, p < 0.001; males 22.7% vs. 12.3%, p < 0.001). Depression and anxiety were more prevalent in the subjects with known diabetes than in those with normal glucose tolerance but not in the newly-diagnosed diabetes. The OR for depressiveness was 2.0 (1.3; 2.6) in subjects with MetS and 4.2 (2.3; 7.8) in those with known diabetes. CONCLUSIONS: In conclusion, depressiveness and anxiety were associated positively with age and female gender and were more prevalent among subjects with MetS and known diabetes mellitus. PMID- 29185829 TI - A multi-hospital analysis of predictors of oral anticoagulation prescriptions for patients with actionable atrial fibrillation who attend the emergency department. AB - Atrial fibrillation (AF) is the most common arrhythmia and is associated with an increase in the risk of ischemic stroke. The risk of stroke can be significantly decreased by oral anticoagulation (OAC). Our objective was to characterize the filling of OAC prescriptions for patients with actionable AF (new or existing AF with an indication for OAC but not prescribed) and determine the prevalence and predictors of guideline-appropriate therapy at 30 days. This is a multi-hospital, retrospective cohort study of patients who visited the Emergency Department (ED) and had a discharge diagnosis of AF. Patient records were examined to identify demographics, risk factors, and prescription data. Predictors of filling a prescription at 30 days were analyzed. 788 patients with AF were reviewed. 257 patients had actionable AF. Forty one percent (104) had newly diagnosed AF. The mean CHADS2 score was 2 +/- 1. At 30 days after discharge, 25.7% of patients filled a prescription for OAC therapy. Large numbers of patients attending the ED have actionable AF, but rates of guideline-directed OAC at thirty days are low. Only a prescription written by the ED physician (OR 9.89) and documentation of stroke risk stratification in the patients' chart (OR 4.09) were associated with the primary outcome. PMID- 29185830 TI - Median Nerve Injury After Removal of Subdermal Implantable Contraceptive. AB - BACKGROUND: Subdermal implantable contraceptives are highly effective, approved in over 60 countries, and used by millions of women. Due to simple insertion and removal protocols, these procedures are often performed in the outpatient clinic setting, and procedural complications are rare. However, given the location of the implant in the medial antebrachial interval, there is a risk of neurovascular injury, especially with malpositioned or deeply placed implants. METHODS: We present a case of proximal median nerve injury leading to severe neuropathy after attempted removal of a subdermal implantable contraceptive requiring neurolysis and tendon transfers. RESULTS: At 6 months post surgery, the patient regained flexion of the index interphalangeal joints and protective sensation in the thumb and index fingers. CONCLUSIONS: Subdermal implant retrieval can lead to nerve injury, despite the relative simplicity of the procedure. If difficulty is encountered, imaging or open retrieval should be considered. Improvement in function can be gained through operative interventions including neurolysis and tendon transfers in the setting of severe neuropathy.

PMID- 29185832 TI - Regulation of Reactionary Dentine Formation. AB - During the treatment of dental caries that has not penetrated the tooth pulp, maintenance of as much unaffected dentine as possible is a major goal during the physical removal of decayed mineral. Damage to dentine leads to release of fossilized factors (transforming growth factor-beta [TGF-beta] and bone morphogenic protein [BMP]) in the dentine that are believed to stimulate odontoblasts to secrete new "tertiary" dentine (reactionary dentine). This is formed on the pulpal surface of existing dentine and rethickens the dentine. We have previously shown that activation of Wnt/beta-catenin signaling is pivotal for tooth repair in exposed pulp injury, and the pathway can be activated by small-molecule GSK-3 antagonists, resulting in enhanced reparative dentine formation. Here, we use a nonexposed pulp injury model to investigate the mechanisms of reactionary dentine formation in vivo, using small molecules to modulate the Wnt/beta-catenin, TGF-beta, and BMP pathways. We found that a local increase of Wnt activation at the injury site enhances reactionary dentine secretion. In addition, inhibition of TGF-beta, BMP, or Wnt pathways does not impede reactionary dentine formation, although inhibition of TGF-beta and/or BMP signaling does result in more disorganized, nontubular reactionary dentine. This suggests that Wnt/beta-catenin signaling plays no major role in the formation of reactionary dentine, but in common with reparative dentine formation, exogenous elevation of Wnt/beta-catenin signaling can enhance tertiary dentine formation. Release of latent TGF-beta or BMPs from dentine is not required for the deposition of mineral to form reactionary dentine but does play a role in its organization. PMID- 29185833 TI - Disruption of Hif-1alpha enhances cytotoxic effects of metformin in murine squamous cell carcinoma. AB - PURPOSE: In the present study, we investigated whether the disruption of the Hif 1alpha gene affects the sensitivity of SCC VII cells to metformin and also if metformin functions as a radiosensitizer using murine squamous cell carcinoma (SCC VII) cells. MATERIALS AND METHODS: Cultured SCC VII and SCC VII Hif-1alpha deficient cells were incubated with metformin under glucose-free and/or hypoxia mimetic conditions and cell viabilities were measured. Tumor-bearing mice were continuously given 5-bromo-2'-deoxyuridine (BrdU) to label all proliferating cells. Tumor-bearing mice were then subjected to gamma-ray irradiation after the metformin treatment. Immediately after irradiation, cells were isolated from some tumors and incubated with a cytokinesis blocker. The responses of quiescent and total (= proliferating + quiescent) cell populations were assessed based on the frequency of micronuclei using immunofluorescence staining for BrdU. RESULTS: The disruption of Hif-1alpha increased the sensitivity of SCC VII cells to metformin in glucose-free medium. Metformin-induced decreases in the percentage of dead cells in the presence of CoCl2 were partially reduced when Hif-1alpha was disrupted. In vivo, metformin increased the radiosensitivity of SCC VII Hif 1alpha-deficient cells. CONCLUSION: The combination of disruption of Hif-1alpha and metformin effectively enhanced the radiosensitivity of SCC VII cells.

AB - PURPOSE: Ionizing radiation has been associated with adverse effects on the immune system. Currently, there are no effective treatment options to ameliorate these effects. The aim of the present study was to investigate the protective effects of resveratrol against radiation-induced long-term immunosuppression in mice. MATERIALS AND METHODS: Mice were exposed to total body irradiation and treated with resveratrol or vehicle. Several immune parameters were measured, including thymus and spleen weights, T-lymphocyte and B-lymphocyte count in peripheral blood, concanavalin A and lipopolysaccharide induced lymphocyte proliferation. To explore the mechanism, we investigated intracellular ROS level of lymphocytes and mice plasma cytokine levels. RESULTS: Treatment with resveratrol ameliorated TBI-induced atrophy of the thymus and spleen, reduction of lymphocyte count and decline of lymphocyte proliferation. TBI exhibited significantly reduced level of IL-2, IL-4, IL-7 and IFN-gamma compared with the control mice and treatment with resveratrol attenuated the reduction. CONCLUSION: The results of the present study suggest that treatment with resveratrol could ameliorate irradiation induced long-term immune malfunction at least partly via modulation of plasma cytokine. PMID- 29185835 TI - Biometric Differences between Unilateral Chronic Primary Angle Closure Glaucoma and Fellow Non-Glaucomatous Eyes. AB - PURPOSE: To compare biometric differences between eyes with unilateral chronic primary angle-closure glaucoma (PACG) and fellow non-glaucomatous eyes in the same patient. METHODS: Clinical data and imaging records of 17 patients with unilateral PACG were retrospectively reviewed. The fellow eyes with primary angle closure (PAC) or primary angle-closure suspected (PACS) were grouped in Group 1. The PACG eyes were set as Group 2. The biometric parameters of both eyes were measured by IOL-Master, anterior segment optical coherence tomography (AS-OCT), and swept source OCT. RESULTS: The iris area in Group 1 was significantly thicker than that in Group 2 (1.590 +/- 0.267 versus 1.365 +/- 0.352, P = 0.016). Choroidal thickness in the macular region was thicker in Group 1 than in Group 2, with statistical significance at inner temporal grid (282.7 +/- 121.1 versus 191.6 +/- 90.3, P = 0.036), central field (297.4 +/- 130.6 versus 200.1 +/- 96.3, P = 0.029), inner nasal grid (283.1 +/- 128.3 versus 194.8 +/- 91.8, P = 0.040), and average value (265.3 +/- 105.6 versus 191.1 +/- 87.0, P = 0.049). Group 1 also had thicker peripapillary choroidal thickness at 1 o'clock (141.4 +/- 68.4 versus 101.8 +/- 39.0, P = 0.025) and 12 o'clock (141.5 +/- 82.3 versus 104.5 +/- 44.6, P = 0.037) compared to Group 2. The multivariate logistic regression analyses showed that only intraocular pressure was independently associated with PACG and explained 58.3% variance of PACG. CONCLUSIONS: In unilateral PACG, there was significant inter-eye difference in anterior and posterior segment parameters. Longitudinal comparisons are required to further understand the differences in pathology of angle closures. PMID- 29185837 TI - Effects of Negative Affect, Urge to Smoke, and Working Memory Performance (n back) on Nicotine Dependence. AB - BACKGROUND: Three key domains including negative emotionality, incentive salience, and executive function form the core functional elements of addictive behaviors. Variables related to these broader domains have been studied extensively in relation to one another; however, no studies to date, have examined models including variables from all three domains, in relation to nicotine dependence. METHOD: Smokers (N = 117), 65.8% female, 78% white, mean age of 44.4 (SD = 10.8), enrolled in a smoking cessation program completed measures of negative affect (a component of negative emotionality), urge to smoke (incentive salience), and working memory (WM; a core executive function), during a baseline assessment period prior to initiating treatment. RESULTS: Negative affect was associated with greater urge to smoke, and this elevated urge to smoke was associated with higher levels of nicotine dependence. Further, a significant moderated mediation indicated that WM moderated the relationship between increased urge to smoke and nicotine dependence. For those with low to average WM, urge to smoke was significantly related to nicotine dependence; however, for those with higher WM (+1 SD), urge to smoke stemming from negative affect was not associated with nicotine dependence. CONCLUSIONS: To our knowledge, this is the first reported relationship between negative affect, urge to smoke, WM, and nicotine dependence. Although preliminary, results indicate that WM may moderate the relationship between urge to smoke associated with negative affect and nicotine dependence. Treatments targeting WM may be particularly useful for individuals with average to low WM who experience urge to smoke related to negative affect. PMID- 29185838 TI - Cataract Surgery Complications in Uveitis Patients: A Review Article. AB - Uveitis is a leading causes of blindness worldwide, and the development of cataracts is common due to both the presence of intraocular inflammation and the most commonly employed treatment with corticosteroids. The management of these cataracts can be very challenging and often requires additional procedures that can compromise surgical results. The underlying disease affects a relatively young population at higher risk of complications. Preoperative control of inflammation/quiescent disease for at least three months is generally accepted as the minimum amount of time prior to surgical intervention. Phacoemulsification with intraocular lens is the preferred method for surgery, with some studies showing improvement in visual acuity in over 90% of patients. The most common postoperative complications include macular edema, posterior capsule opacification, recurrent or persistent inflammation, glaucoma, epiretinal membrane and IOL deposits, or dislocation. Despite the potential complications, cataract surgery in uveitis patients is considered a safe and successful procedure. PMID- 29185836 TI - Exome-chip meta-analysis identifies association between variation in ANKRD26 and platelet aggregation. AB - Previous genome-wide association studies (GWAS) have identified several variants associated with platelet function phenotypes; however, the proportion of variance explained by the identified variants is mostly small. Rare coding variants, particularly those with high potential for impact on protein structure/function, may have substantial impact on phenotype but are difficult to detect by GWAS. The main purpose of this study was to identify low frequency or rare variants associated with platelet function using genotype data from the Illumina HumanExome Bead Chip. Three family-based cohorts of European ancestry, including ~4,000 total subjects, comprised the discovery cohort and two independent cohorts, one of European and one of African American ancestry, were used for replication. Optical aggregometry in platelet-rich plasma was performed in all the discovery cohorts in response to adenosine diphosphate (ADP), epinephrine, and collagen. Meta-analyses were performed using both gene-based and single nucleotide variant association methods. The gene-based meta-analysis identified a significant association (P = 7.13 * 10-7) between rare genetic variants in ANKRD26 and ADP-induced platelet aggregation. One of the ANKRD26 SNVs - rs191015656, encoding a threonine to isoleucine substitution predicted to alter protein structure/function, was replicated in Europeans. Aggregation increases of ~20-50% were observed in heterozygotes in all cohorts. Novel genetic signals in ABCG1 and HCP5 were also associated with platelet aggregation to ADP in meta analyses, although only results for HCP5 could be replicated. The SNV in HCP5 intersects epigenetic signatures in CD41+ megakaryocytes suggesting a new functional role in platelet biology for HCP5. This is the first study to use gene based association methods from SNV array genotypes to identify rare variants related to platelet function. The molecular mechanisms and pathophysiological relevance for the identified genetic associations requires further study.

PMID- 29185840 TI - Single-Dose Levonorgestrel Emergency Contraception and Silent Barriers to Its Access: Is It Really Just One Step? AB - BACKGROUND: Single-dose levonorgestrel has been legally available over the counter in the United States without age restriction since 2013. The objective of this study was to discover if there are barriers to access and to determine if such barriers vary based on the gender of the person making the purchase. MATERIALS AND METHODS: A male and female caller contacted 146 Richmond, Virginia pharmacies listed on the Plan B One Step(r) website. Ultimately, these callers interviewed 90 pharmacies via phone and used a rehearsed standardized script to ask eight questions regarding emergency contraception (EC) in relation to availability, age restrictions, parental consent, counseling requirements, and a male's ability to purchase the product. The statistical data were analyzed using Fisher's exact test. RESULTS: Pharmacy employees provided incorrect information to both men and women regarding age restrictions for purchasing Plan B One Step 51% of the time. However, only seven of the pharmacy employees counseled that males were unable to purchase the medication. Both callers received correct information regarding parental consent and in-store counseling at the time of purchase. Pharmacy technicians provided the majority of information, and the male caller was more likely to be transferred to another person when requesting the medication (9 vs. 0 transfers for the male and female callers, respectively). CONCLUSION: Given the inconsistent data provided to the public regarding the purchase of EC, clinicians are obligated to convey accurate up-to-date information to patients about emergency contraceptive products as part of their counseling and should not assume that consumers receive accurate information when inquiring about over-the-counter EC. PMID- 29185841 TI - Inhibitory Effect of Amitriptyline on the Impulse Activity of Cold Thermoreceptor Terminals of Intact and Tear-Deficient Guinea Pig Corneas. AB - PURPOSE: Chronic dryness of the ocular surface evokes sensitization of corneal cold-sensitive neurons through an increase of sodium currents and a decrease of potassium currents, leading to the unpleasant dryness and pain sensations typical of dry eye disease. Here, we explored the effects of amitriptyline, a voltage gated Na+ channel blocker used for the treatment of depression and chronic pain, on nerve terminal impulse (NTI) activity of cold-sensitive nerve terminals recorded in intact and tear-deficient guinea pig corneas. METHODS: Main lachrymal gland was surgically removed in anesthetized guinea pigs to induce chronic tear deficiency. Four to 6 weeks afterward, animals were sacrificed and both corneas placed in a perfusion chamber superfused at 34 degrees C. Thermal stimuli were induced by changing the solution temperature from 34 degrees C to 20 degrees C (cooling ramp) and from 34 degrees C to 50 degrees C (heating ramp). Spontaneous and stimulus-evoked NTIs of cold-sensitive nerve terminals were recorded before, during, and after perfusion with solutions containing amitriptyline at different concentrations (3-30 MUM). RESULTS: Perfusion with amitriptyline inhibited irreversibly and in a concentration-dependent manner the spontaneous NTI activity of cold thermoreceptors of intact corneas. This effect was less evident in tear deficient corneas. In addition, amitriptyline (10 MUM) attenuated the maximal response to cooling ramps without changing cold threshold in intact but not in tear-deficient corneas. Only cold thermoreceptors with low cooling threshold values were sensitive to amitriptyline. CONCLUSION: Amitriptyline effectively reduces the activity of cold thermoreceptors, although its efficacy is different in intact and tear-deficient corneas, which might be due to the changes induced by ocular dryness in the expression of the various voltage-gated Na+ channels responsible of the action potential generation and propagation. PMID- 29185842 TI - Characterizing a Hidden Group of At-Risk Drinkers: Epidemiological Profiles of Alcohol-Use Disorder Diagnostic Orphans. AB - BACKGROUND: Drinkers who report some symptoms of alcohol-use disorder (AUD) but fail to meet full criteria are "diagnostic orphans." To improve risk-reduction efforts, we sought to develop better epidemiologic profiles of this underrecognized subgroup. METHODS: This study estimated the population prevalence and described AUD symptoms of diagnostic orphans using the 2012-2013 National Epidemiological Survey of Alcohol and Related Conditions-III. Multivariate logistic regression was used to model odds of being a diagnostic orphan or meeting mild, moderate, and severe AUD criteria versus no AUD symptoms. Models were adjusted for the complex survey design using sampling weights and survey procedures (e.g., proc surveylogistic). RESULTS: Among drinkers, 14% of men and 11% of women were classified as diagnostic orphans. The most common symptoms were drinking more or for longer periods than intended, wanting or trying unsuccessfully to quit or cut back, and drinking in ways that increased risk of injury. We noted broad similarities between diagnostic orphans and mild/moderate AUD groups. There were no differences in odds of diagnostic orphans status by race/ethnicity; however, female gender was associated with lower odds of diagnostic orphan status and all levels of AUD. Individual history of AUD, family history of problem drinking, concurrent smoking, and concurrent marijuana use were associated with greater odds of problem drinking, with stronger associations as AUD severity increased. CONCLUSIONS: Diagnostic orphans remain a sizeable and overlooked population of problem drinkers. Clarifying the array of symptoms and cooccurring disorders can improve screening and facilitate alcohol risk-reduction intervention efforts. PMID- 29185843 TI - Morphological and chromosomal abnormalities in gamma radiation-induced mutagenized faba bean genotypes. AB - PURPOSE: This study was conducted to evaluate and compare the influence of gamma radiations on morphological and chromosomal abnormalities in twenty mutagenized faba bean populations, representing first and second generations (M1 and M2) of five faba bean genotypes. MATERIALS AND METHODS: Five faba bean genotypes were exposed at two doses of gamma radiations (25 and 50 Gy). For determining the types of chromosomal aberrations caused by the gamma radiation, mitotic and meiotic cells were isolated from root tips and pollen mother cells, respectively. RESULTS: The M1 generations of the five genotypes varied for sensitivity to gamma radiations, for seedling emergence. The genotype Skah 2 was more sensitive than other genotypes, the order of sensitivity of other genotypes was Misr 3 > ILB 4347 > Hassawi 2 > Hassawi 3. However, seedling emergence of the M2 generations was not as much reduced as that of the M1 generations. Ten different chlorophyll deficient mutants were identified among the M2 generations. Gamma radiations also caused the development of abnormal leaflets, flowers and pollen grains. The most common types of chromosome aberrations in the mitotic cells were stickiness, laggard, and chromosome breaks, whereas the most common types in the meiotic cells were stickiness and disturbed polarity. CONCLUSION: The gamma radiation decreased the seedling emergence and induced a wide range of morphological and chromosomal abnormalities in faba bean. PMID- 29185844 TI - Postoperative Complications of Scleral Buckling. AB - Scleral buckling has an important role in the repair of certain categories of rhegmatogenous retinal detachments. These include detachments in young phakic patients, detachments associated with dialysis, and also in conjuction with vitrectomy in patients who have sustained trauma or have developed proliferative vitreoretinopathy. However, it can be associated with significant postoperative complications. The most important ones are refractive change, intrusion or extrusion, infection, globe ischemia, and choroidal detachments, amongst others. Careful planning, appropriate patient selection, and good intraoperative technique can reduce the rate of these complications. PMID- 29185845 TI - A Qualitative Study on the Effects of Psychoactive Substance use upon Artistic Creativity. AB - BACKGROUND: Psychoactive substance use has often been claimed to help generate and facilitate the artistic creative process. AIMS: This study explored the role of artists' substance use in their creative processes and their efforts to balance between enhancement and relaxation. METHODS: Semistructured interviews concerning the artistic creative process and the role of psychoactive substance use were recorded with 72 artists and analyzed using content analysis. The participants were classified according to their substance use in three groups (Cannabis Group, Alcohol Group, and Control Group). RESULTS: Results show that both alcohol and cannabis were used to facilitate creativity and the emotional states that are necessary for the artistic creative process. Participants in the Control group reported that listening to music might function as a mind-altering tool. It was also found that for some artists, substance use is not only characteristic to creation, but it is also part of their everyday lives. CONCLUSION: Artists are aware of the balancing phenomenon during the artistic creative process. Whether psychoactive substance(s) or other environmental stimuli (such as music) are used to reach the required effect appears to depend upon the individual. PMID- 29185846 TI - Adverse Childhood Experiences (ACEs) and Alcohol Abuse among South Carolina Adults. AB - BACKGROUND: Adverse childhood experiences (ACEs) have been associated with negative adult health outcomes, including alcohol misuse. The impact of ACEs on alcohol use may vary by gender, with ACEs impacting women more than men in coping with adulthood stressors. OBJECTIVES: The objective of this study is to examine the gender-specific relationships between ACEs and self-reported binge drinking and heavy drinking in adulthood among South Carolina residents. METHODS: This study analyzed a sample of 8492 respondents who completed the 2014 or 2015 South Carolina Behavioral Risk Factor Surveillance System (BRFSS) survey. Logistic regression was used to examine the impact of types and the number of ACEs on binge drinking and heaving drinking in adulthood. RESULTS: Thirty-seven percent of men and 22.8% of women survey respondents reported binge drinking and 12.2% of men and 4.1% of women reported heavy drinking. Almost all categories of ACE were associated with increased odds of reporting binge and heavy drinking; household mental illness had the greatest odds for men (aOR 1.31, 95% CI 1.30-1.33) and emotional abuse had the greatest odds for women (aOR 1.42, 95% CI 1.40-1.43). Men and women with four or more ACEs had greater odds of reporting binge and heavy drinking compared to their counterparts. Conclusions/Importance: Given the potential for negative outcomes associated with alcohol misuse and transmission of risky alcohol-related behaviors from parent to child, strategies that utilize a multigenerational approach could have a large impact on population health. PMID- 29185847 TI - Screening for Psychological Conditions in Infertile Women: Provider Perspectives. AB - PURPOSE: To determine if reproductive specialists are screening new patients for depression or anxiety, explore possible reasons why providers are not screening, and assess physician's views about the impact of mental health disorders on fertility. MATERIALS AND METHODS: Cross-sectional exploratory study in which 86 practicing reproductive physicians filled out a 20-question survey regarding mental health screening and perception of psychological disorders on reproduction. RESULTS: The majority of infertility providers believe psychological conditions negatively impact pregnancy success (75%); however, most providers are not formally screening patients for depression or anxiety (28%). Providers who did not screen for depression were more likely to be uncomfortable assessing patients for mental health disorders and to work in a private practice setting. CONCLUSIONS: This study finds that most infertility specialist respondents believe that mental health conditions negatively impact reproductive outcomes; however, few of these providers are screening for psychological disorders in infertile women. Reasons why providers are not screening infertility patients for psychological disorders include lack of time and unfamiliarity with recommendations for treatment of mental health conditions. Implementing a rapid screen for anxiety and depression and providing easily assessable succinct educational updates to fertility providers on current treatment options for mental health disorders may allow affected patients to be treated sooner, and ultimately, may improve fertility outcomes. PMID- 29185849 TI - RAS ubiquitylation modulates effector interactions. AB - RAS proteins function as molecular switches that regulate cellular growth by cycling between active GTP- and inactive GDP bound states. While RAS activity is modulated by factors (guanine nucleotide exchange and GTPase activating proteins) that control levels of active Ras-GTP, RAS proteins also undergo a number of post translational modifications that regulate their function. One such modification is ubiquitylation. Monoubiquitylation of KRAS at lysine 147 (mUbRAS) enhances Ras activation and promotes signaling through the RAF and Phosphoinositide 3-Kinase (PI3K) signaling pathways. We have previously shown that mUbRAS leads to activation of RAS through a defect in GTPase activating protein (GAP) mediated downregulation, similar to the action of most oncogenic mutations. Consistent with these findings, we now show that mUbRASimpairsRAS binding to the p120 GAP catalytic domain. Mutations in activated G12V RAS that prevent ubiquitylaton at 147 show a decrease in tumorigenesis, suggesting that in addition to activating KRAS, monoubiquitylation at this site may promote downstream signaling and transformation. To investigate whether mUbRAS alters RAS effector interactions, we chemically ubiquitylated KRAS at residue 147 and characterized binding of mUbRAS to RAS binding domains (RBDs) from three distinct downstream effectors that play key roles in RAS-mediated transformation. Results from these studies show a decrease in binding of mUbRAS (7-10-fold) relative to the CRAF RAS Binding Domain (RBD), the catalytic subunit of Phosphoinositide 3-Kinase catalytic gamma (PI3Kcgamma) and RALGDS RBD. Intriguingly, we find that mUbRAS shows greatly enhanced (> 40-fold) binding to the CRAF RBD when bound to GDP. These findings, taken together, suggest that mUbRASmay promoteactivation of RAS through a GAP defect, and facilitate RAF association and MAPK signaling in a nucleotide independent manner. PMID- 29185850 TI - Polymorphic Microsatellite Markers for Solen grandis and Their Cross-Species Amplification in Three Other Species. AB - The grand jackknife clam Solen grandis is a commercially important mollusk species, but has been suffering from severe population decline due to over exploitation and habitat destruction in China. To promote a conservation program for this species, it is necessary to evaluate its genetic diversity and population genetics. In this study, 10 novel polymorphic microsatellite makers were developed and characterized from the S. grandis through high throughput sequencing. The number of alleles at each locus ranged from 10 to 34 with an average of 20.8 alleles per locus. The observed and expected heterozygosities varied from 0.433 to 1.000 and from 0.696 to 0.976, with an average of 0.793 and 0.884, respectively. The polymorphism information content (PIC) value ranged from 0.633 (Sg43838) to 0.958 (Sg3754), with an average of 0.858. The cross-species amplification transferability of 10 loci to three closely related species ranged from 4.17 to 62.5%. These microsatellite loci will be useful for further investigation of population structure and conversation genetics of this species. PMID- 29185848 TI - Monoclonal antibodies targeting the disintegrin-like domain of ADAMDEC1 modulates the proteolytic activity and enables quantification of ADAMDEC1 protein in human plasma. AB - Decysin-1 (ADAMDEC1) is an orphan ADAM-like metalloprotease with unknown biological function and a short domain structure. ADAMDEC1 mRNA has previously been demonstrated primarily in macrophages and mature dendritic cells. Here, we generated monoclonal antibodies (mAbs) against the mature ADAMDEC1 protein, as well as mAbs specific for the ADAMDEC1 pro-form, enabling further investigations of the metalloprotease. The generated mAbs bind ADAMDEC1 with varying affinity and represent at least six different epitope bins. Binding of mAbs to one epitope bin in the C-terminal disintegrin-like domain efficiently reduces the proteolytic activity of ADAMDEC1. A unique mAb, also recognizing the disintegrin-like domain, stimulates the caseinolytic activity of ADAMDEC1 while having no significant effect on the proteolysis of carboxymethylated transferrin. Using two different mAbs binding the disintegrin-like domain, we developed a robust, quantitative sandwich ELISA and demonstrate secretion of mature ADAMDEC1 protein by primary human macrophages. Surprisingly, we also found ADAMDEC1 present in human plasma with an approximate concentration of 0.5 nM. The presence of ADAMDEC1 both in human plasma and in macrophage cell culture supernatant were biochemically validated using immunoprecipitation and Western blot analysis demonstrating that ADAMDEC1 is secreted in a mature form. PMID- 29185851 TI - The Preference for Social Affiliation Renders Fish Willing to Accept Lower O2 Levels. AB - Animals are bombarded with information about their environment and must select and interpret the relevant cues to make behavioral adjustments critical to survival. How animals integrate and balance the many signals they receive about their environment is rarely assessed. We investigated how signals from the social and physical environment interact to influence environmental preferences in the endemic Tanganyikan cichlid Neolamprologus pulcher. Specifically, we explored how fish respond to the physiological challenge of declining O2 levels in light of embedded social preferences using a modified shuttle box apparatus to test O2 preferences. In the presence of a conspecific, the average (preferred) partial pressure of oxygen (Po2) and minimum Po2 experienced were significantly lower ([Formula: see text] and [Formula: see text] kPa, respectively) than in trials without a conspecific ([Formula: see text] and [Formula: see text] kPa, respectively). Fish with conspecifics also spent more time in the low Po2 zone of the shuttle box and moved between the high and low Po2 zones less frequently. Hence, O2 preferences were modified, and fish willingly remained in an area of continuously declining O2 availability to associate with a conspecific. The O2 preferences of an individual during social trials correlated with its excess postexercise O2 consumption following an exhaustive chase but not with its aerobic scope, routine O2 consumption rate, or body mass. These results suggest that some aspects of respiratory and metabolic physiology (such as the propensity to use anaerobic metabolism) but not others (such as O2 transport capacity) underpin some variation in social behavior under environmental stress. PMID- 29185852 TI - Lethal Fascioliasis in Capybaras ( Hydrochoerus hydrochaeris) in Brazil. AB - The liver fluke Fasciola hepatica (Trematoda: Fasciolidae) causes fascioliasis, which affects mostly domestic ruminants and humans worldwide. This parasite has an Old World origin and was introduced into the New World by European colonizers. Capybara ( Hydrochoerus hydrochaeris) is the largest living rodent species, with adults weighing over 60 kg. We report a fascioliasis outbreak caused by F. hepatica that reduced a capybara group from 21 to 2 animals within a 9-mo period. Animal infection and associated lesions were confirmed by postmortem examinations that revealed extensive liver damage associated with the presence of large number of adult and immature forms of F. hepatica. Both macroscopic and microscopic alterations in the liver were compatible with acute fascioliasis, which is characterized by a large parasite burden in the liver. Taxonomic identification of flukes collected from capybara livers were confirmed by molecular methods, which generated a mitochondrial NADH dehydrogenase I (NDI) gene partial sequence that was 100% identical to a F. hepatica NDI sequence from the United Kingdom. This is the first report of deleterious effects caused by F. hepatica in capybaras, highlighting the potential harm caused by this exotic parasite in the capybara. PMID- 29185853 TI - Synthesis, characterization and biological evaluation of C5'-N cyclopropylcarboxamido-C6-amino-C2-alkynylated purine nucleoside analogues. AB - In an effort to develop potent antibacterial and anticancer agents, a series of C5'-N-cyclopropylcarboxamido-C6-amino-C2-alkynylated purine nucleoside analogues 11a-g were synthesized through a Sonogashira cross-coupling reaction. The nine step synthesis is easy to perform, and employs commercially available reagents. 2 Iodo-5'-N-cyclopropylcarboxamidoadenosine (9) was used as the starting intermediate for the synthesis of title derivatives 11a-g. Synthetic intermediates (2-9) and final products (11a-g) were appropriately characterized by IR, 1H NMR, 13C NMR and mass spectroscopy. The synthesized purine nucleoside analogues (11a-g) were evaluated for their in vitro antibacterial activity against two gram-positive and two gram-negative bacteria. They were then tested for cytotoxicity against MDA-MB-231 and Caco-2 cancer cell lines to determine their anti-cancer activity. Among the tested compounds, compounds 11c and 11g showed most potent antibacterial activity against S.aureus and P.aeruginosa bacterial strains. Compounds 11b and 11e displayed considerable IC50s of 7.9 and 6.8 ug/mL, respectively, vs MDA-MB-231 cell lines of 7.5 and 8.3 ug/mL, respectively, against the Caco-2 cell lines. PMID- 29185854 TI - Molecular Epidemiology of Methicillin-Resistant Staphylococcus aureus in Cystic Fibrosis Patients from Argentina. AB - Methicillin-resistant Staphylococcus aureus (MRSA) colonization in cystic fibrosis (CF) patients is an increasing problem in many countries. In our Respiratory Center at the Hospital de Ninos "Dr. Ricardo Gutierrez", Buenos Aires, Argentina, the prevalence has climbed from 23% in 1995 up to 32% in 2011. Our objective was to analyze the diversity of MRSA isolates recovered from respiratory samples of CF patients attending our center, characterizing their phenotypes and clonal distribution. Therefore, a prospective study was conducted on all CF patients attending the pediatric Respiratory Center between June 2012 and May 2013 to collect MRSA isolates. Antibiotic susceptibility testing, multilocus sequence typing, pulsed-field gel electrophoresis, spa typing, and agr genotyping were performed on collected isolates. The prevalence of MRSA during this period was 34.2%, and 71.9% of the patients were infected with isolates that carried SCCmec IV. High resistance rates were detected for gentamicin, erythromycin, clindamycin, ciprofloxacin, and rifampicin. Strains related to the community-associated MRSA clones, ST5-IV and ST30-IV, were the most frequently recovered. Remarkably, even though most of the isolates were related to these clones, the rate of multi-resistance shown in CF patients was higher than that reported for the same lineages recovered from other infections in our country. PMID- 29185855 TI - Production of a germline-humanized cetuximab scFv and evaluation of its activity in recognizing EGFR- overexpressing cancer cells. AB - The aim of this study was to produce a humanized single chain antibody (scFv) as a potential improved product design to target EGFR (Epidermal Growth Factor Receptor) overexpressing cancer cells. To this end, CDR loops of cetuximab (an FDA-approved anti-EGFR antibody) were grafted on framework regions derived from type 3 (VH3 and VL3 kappa) human germline sequences to obtain recombinant VH and VL domainslinked together with a flexible linker [(Gly4Ser)3] to form a scFv. Codon optimized synthetic gene encoding the scFv (with NH2-VH-linker-VL-COOH orientation) was expressed in E. coli OrigamiTM 2(DE3) cells and the resultant scFv purified by using Ni-NTA affinity chromatography. The scFv, called cet.Hum scFv, was evaluated in ELISA and immunoblot to determine whether it can recognize EGFR. The scFv was able to recognize EGFR over-expressing cancer cells (A-431) but failed to detect cancer cells with low levels of EGFR (MCF-7 cells). Although the affinity of the scFv forA-431 cells was 9 fold lower than that of cetuximab, it was strong enough to recognize these cells.

AB - Two new nickel(II) and copper(II) complexes of 2-(Furan-2-yl)-1H-Imidazo[4,5 f][1,10]Phenanthroline (FIP) and 2-(thiophen-2-yl)-1H-imidazo[4,5 f][1,10]phenanthroline (TIP), imidazophen derivatives were synthesized. The structures of the compounds were determined by UV-visible and FT-IR spectroscopic methods and elemental analysis. The biological activities of Ni and Cu complexes, as anticancer agents, were tested against chronic myelogenous leukemia cell line, K562, at micromolar concentration. The MTT studies showed Cc50 values are 21 and 160 uM for Cu and Ni(II) complexes, respectively; suggesting that Ni (II) complex has Cc50 almost seven times of that obtained for cisplatin. Biological activity of the Ni(II) and Cu(II) complexes were also assayed against selective microorganisms by disc diffusion method. These results showed that the Cu(II) complex is antifungal agent but Ni(II) complex has antibacterial activity.

AB - Antimicrobial resistance was tested in Escherichia coli isolated from feces (n = 660) of red deer, roe deer, fallow deer, European bison, and wild boar shot in regional forests in Poland during two winter hunting seasons. Indicator E. coli (n = 542) was resistant against 11 of 14 tested compounds, mostly sulfamethoxazole, streptomycin, ampicillin, trimethoprim, and tetracycline (1.3 6.6% range). No significant differences were observed between boar and ruminant isolates. Most of deer and bison isolates showed no resistance. Selective screening of wildlife samples revealed 1.7% prevalence of cephalosporin-resistant E. coli found mostly in wild boars. They produced extended-spectrum beta lactamases (blaCTX-M-1, blaCTX-M-15) and plasmid-mediated AmpC-type cephalosporinase (blaCMY-2). The majority of the isolates originated from boars shot in a narrow time frame and space; therefore, common antimicrobial selection pressure in the environment was assumed. Three E. coli isolates carried plasmid mediated quinolone resistance genes (qnrS1/S3). No transferable colistin resistance mechanisms were found in two resistant E. coli. Transferability of resistance was proved in a single pAmpC-positive isolate carrying IncI1-alpha 95 kb plasmid. No cephalosporin-resistant E. coli harbored pathogenicity markers; therefore, they might be considered a vector of resistance determinants, but not a pathogen themselves. PMID- 29185859 TI - Burden of Rifampicin- and Methicillin-Resistant Staphylococcus aureus in Italy. AB - Rifampicin is one of the major drugs used on its own and also in combination to treat numerous infections sustained by methicillin-resistant Staphylococcus aureus (MRSA). In Italy, rifampicin resistance (RIF-R) is increasing in multidrug resistant-MRSA isolates (16.4%), with respect to Europe (5.7%). In our study, the relationship between clones, rpoB mutations, and susceptibility profiles in 50 RIF-R MRSA isolated from hospitalized patients was evaluated. Antimicrobial susceptibility testing was performed by the broth microdilution method. Isolates were typed by MLST/SCCmec/spa-typing. The rpoB gene was analyzed by PCR and sequence analysis. RIF-R isolates were 60% heterogeneous vancomycin-intermediate S. aureus (hVISA) and 22% daptomycin nonsusceptible and belonged to the major MRSA clones: ST228-SCCmec I (44%), ST8-SCCmec IV (18%), ST239-SCCmec III (16%), ST5-SCCmec II (14%), and ST22-SCCmec IVh (4%). Thirteen diverse RpoB amino acid substitutions were identified. Half of the strains harbored the H481N substitution, conferring low-level resistance. Different single mutations at the equivalent locus (H481D; H481Y) or in other loci, and multiple mutations conferred high-level resistance. In conclusion, this study investigated the nature of RIF-R in Italy among RIF-R-MRSA strains, finding a prevalence of ST228, strongly associated with reduced susceptibility to glycopeptides (hVISA). The spread of RIF-R strains in clinical settings represents a serious threat, due to their complex resistance nature even to new anti-Gram-positive drugs, making these infections particularly difficult to treat.

AB - Mouse mammary tumor virus (MMTV) is considered to be responsible for breast tumor development in mice. In several instances sequences homologous to the genome of this virus have been reported in human breast cancer samples. Here we aimed to evaluate MMTV involvement in human breast cancer development. DNA was extracted from 118 formalin fixed and paraffin embedded malignant (n = 59) and benign (n = 59) breast lesions. Using two sets of outer and inner MMTV-like envelope specific primers, in a nested PCR setup, MMTV genome was detected in 19 samples out of 59 (%32.2) cases of breast carcinomas, while in non-malignant breast tissue samples, only 3 samples out of 59 (%5) were positive. The difference was statistically highly significant (p < 0.001). Alignment of PCR amplified sequences with BR6, GR and C3H mouse mammary tumor virus strains emerged to be around 99% identical which is indicative of tumor tissue infection by an exogenous mouse MMTV genome. PMID- 29185861 TI - Of rings and spines: The multiple facets of Citron proteins in neural development. AB - The Citron protein was originally identified for its capability to specifically bind the active form of RhoA small GTPase, leading to the simplistic hypothesis that it may work as a RhoA downstream effector in actin remodeling. More than two decades later, a much more complex picture has emerged. In particular, it has become clear that in animals, and especially in mammals, the functions of the Citron gene (CIT) are intimately linked to many aspects of central nervous system (CNS) development and function, although the gene is broadly expressed. More specifically, CIT encodes two main isoforms, Citron-kinase (CIT-K) and Citron-N (CIT-N), characterized by complementary expression pattern and different functions. Moreover, in many of their activities, CIT proteins act more as upstream regulators than as downstream effectors of RhoA. Finally it has been found that, besides working through actin, CIT proteins have many crucial functional interactions with the microtubule cytoskeleton and may directly affect genome stability. In this review, we will summarize these advances and illustrate their actual or potential relevance for CNS diseases, including microcephaly and psychiatric disorders. PMID- 29185862 TI - The Effects of 2'-O-Methoxyethyl Oligonucleotides on Renal Function in Humans. AB - Systemically administered 2'-O-methoxyethyl (2'MOE) antisense oligonucleotides (ASOs) accumulate in the kidney and metabolites are cleared in urine. The effects of eleven 2'MOE ASOs on renal function were assessed in 2,435 patients from 32 phase 2 and phase 3 trials. The principle analysis was on data from 28 randomized placebo-controlled trials. Mean levels of renal parameters remained within normal ranges over time across dose groups. Patient-level meta-analyses demonstrated a significant difference between placebo-treated and 2'MOE ASO-treated patients at doses >175 mg/week in the percentage and absolute change from baseline for serum creatinine and estimated glomerular filtration rate. However, these changes were not clinically significant or progressive. No dose-related effects were observed in the incidence of abnormal renal test results in the total population of patients, or subpopulation of diabetic patients or patients with renal dysfunction at baseline. The incidence of acute kidney injury [serum creatinine >=0.3 mg/dL (26.5 MUM) increases from baseline or >=1.5 * baseline] in 2'MOE ASO treated patients (2.4%) was not statistically different from placebo (1.7%, P = 0.411). In conclusion, in this database, encompassing 32 clinical trials and 11 different 2'MOE ASOs, we found no evidence of clinically significant renal dysfunction up to 52 weeks of randomized-controlled treatment. PMID- 29185863 TI - Comparison of the diastereoisomeric excess of uridine, inosine and adenosine cyanohydrins determined by HPLC-DAD and 1H NMR. AB - The separation of the diastereoisomers of the nucleoside derivatives of uridine, inosine and adenosine was performed by HPLC using chiral and no chiral columns, it was observed with the no chiral columns the resolution was good enough to determine diastereoisomeric excess. These methods were compared with 1H NMR, and no significant differences were observed between the three techniques. Diastereoisomeric uridine (3a), inosine (3b) and adenosine (4c) cyanohydrins were resolved by 1H nuclear magnetic resonance (1H NMR), chiral normal phase-high performance liquid chromatography-diode array detector (NP-HPLC-DAD) and reversed phase (RP-HPLC-DAD); these methods allowed the assesment of the percent diastereoisomeric excess (% de) of the nucleosidic cyanohydrins of 3a (4, 6 and 4), 3b (10, 8 and 6) and 4c (4, 4 and 4). To the best of our knowledge, there are no reports using analytical techniques for the separation of the epimers of 3a, 3b and 4c.

AB - Lesch-Nyhan disease (LND) is a rare X-linked inherited neurogenetic disorder of purine metabolism in which the enzyme, hypoxanthine-guanine phosphoribosyltransferase (HGprt) is defective. The authors report a novel point mutation that led to HGprt-related neurological dysfunction (HND) in a family in which there was a missense mutation in exon 6 of the coding region of the HPRT1 gene: g.34938G>T, c.403G>T, p.D135Y. Molecular diagnosis is consistent with the genetic heterogeneity of the HPRT1 gene responsible for HGprt deficiency. It allows fast, accurate carrier detection and genetic counseling.

This is called a conditional survival distribution. In this paper, we show that one-sample estimation, two-sample comparison and regression analysis of conditional survival distributions can be conducted using the regular methods for unconditional survival distributions that are provided by the standard statistical software, such as SAS and SPSS. We conduct extensive simulations to evaluate the finite sample property of these conditional survival analysis methods. We illustrate these methods with real clinical data. PMID- 29185866 TI - Eye-Movement Evidence for Object-Based Attention in Chinese Reading. AB - Is attention allocated to only one word or to multiple words at any given time during reading? The experiments reported here addressed this question using a novel paradigm inspired by classic findings on object-based attention. In Experiment 1, participants ( N = 18) made lexical decisions about one of two spatially colocated Chinese words or nonwords. Our main finding was that only the attended word's frequency influenced response times and accuracy. In Experiment 2, participants ( N = 30) read target words embedded in two spatially colocated Chinese sentences. Our key finding here was that only target-word frequencies influenced looking times and fixation positions. These results support the hypothesis that words are attended in a strictly serial (and perhaps object based) manner during reading. The theoretical implications of this conclusion are discussed in relation to models of eye-movement control during reading and the conceptualization of words as visual objects. PMID- 29185867 TI - Change of olfactory function as a marker of inflammatory activity and disability progression in MS. AB - BACKGROUND: Impaired olfactory threshold has been reported in early inflammatory phases of MS, while impaired odor identification was associated with more widespread disability. OBJECTIVE: To prospectively assess the development of olfactory function and its correlation with relapse and disability progression. METHODS: In this prospective, 3-year longitudinal study on 151 MS patients and 30 healthy controls, three different qualities of olfactory function (threshold, discrimination, and identification) were quantified using the Sniffin' Sticks test. The influence of relapses and disability on olfactory function was analyzed at different time points and in a multivariate model. RESULTS: Discrimination and identification capability significantly worsened over 3 years, while threshold did not. Threshold was markedly impaired in patients with relapse activity within 12 months, recovered in the absence of relapse, and was associated with a 2.5 fold increased risk of relapse. Deterioration of discrimination and identification was irreversible and both strongly associated with and predictive of EDSS progression. CONCLUSION: Olfactory function changes over time in MS. Threshold impairment is transient and predicts inflammatory disease activity, while odor identification and discrimination are associated with disability progression. Olfactory dysfunction might be a useful and easily obtainable parameter to monitor patients with regard to inflammation and neurodegeneration in MS. PMID- 29185868 TI - Three case studies of nonparaneoplastic limbic encephalitis (NPLE) in young adult males: Onset, course, and recovery following rehabilitation services. AB - Limbic encephalitis (LE) is a rare neurological disorder characterized by inflammation of the brain caused by autoimmunity or infection. LE has been a difficult to define and diagnose disorder due to the insidious and nonspecific (e.g., irritability, low mood, short-term memory complaints) presentation of early symptoms, as well as inconsistent findings on neuroimaging, lumbar puncture serum analysis, and electroencephalogram. Seizures, memory problems, and psychiatric disturbance are among the earliest and most prominent clinical features. This manuscript describes three adolescent males who developed LE and became psychotic, needed inpatient care, were trialed on various psychotropic medications, and exhibited lingering cognitive and psychiatric issues, though generally had very positive recoveries and return to community activities. There was no history of psychiatric disturbance, developmental disorder, or learning difficulties in any of these three young men. Two of the three cases exhibited a long, insidious symptom onset. None of the adolescents benefitted from antipsychotic medications and did not begin to experience improvement and eventual recovery until intravenous immunoglobulin (IVIG) was added to their treatment regimen. Neuropsychological consultation and team education was helpful in each of these cases. Neuropsychological findings for each individual are presented. PMID- 29185870 TI - Retaliation or selfishness? An rTMS investigation of the role of the dorsolateral prefrontal cortex in prosocial motives. AB - Equity, fairness and cooperative behavior are crucial for everyday social interactions. Recent neuroimaging studies suggest that the dorsolateral prefrontal cortex (DLPFC) is involved in the evaluation of violations of fairness rules, though difficulties remain to determine its role in implementing retaliating or forgiving responses to unfairness. Accordingly, we applied repetitive transcranial magnetic stimulation (rTMS) to the left and right DLPFC and investigated the impact of the DLPFC on retaliation and selfishness using a sequential neuroeconomic task establishing a role reversal. That is, participants first played an Ultimatum Game (in the role of a recipient) against fair or unfair proposers, followed by a Dictator Game in the role of a proposer. Following inhibition of the right DLPFC, subjects showed an increased punishment rate regarding previously unfair opponents. Surprisingly, previously fair opponents were also treated less fairly after rTMS to the right DLPFC, but not after left or sham rTMS. Previous work suggests that the right DLPFC provides "top-down" cognitive control over prepotent emotional responses to unfairness. Our results indicate, however, that the right DLPFC may be involved in controlling selfish behavior and that its suppression leads to maximization of one's own benefit, regardless of another's fairness or unfairness in previous encounters. PMID- 29185871 TI - Psychometric and Faciometric Support for observable Facial Feminization in Gay Men. AB - Though male homosexuality appears to be evolutionarily paradoxical, phenotypic feminization has been offered as a route for three current models positing a genetic basis for male homosexuality. We tested whether facial feminization is observable in gay men in two studies. In Study 1, using two composite images of gay and of heterosexual men, naive participants (N = 308) rated the "gay" face more highly on stereotypically feminine traits and actual femininity and the "heterosexual" face more highly on stereotypically masculine traits and actual masculinity. In Study 2, faciometrics of 428 Internet images of gay (N = 219) and heterosexual men were analyzed along six sexually dimorphic ratios. The faciometrics of gay men were more feminine, both in gestalt terms and for five of the six individual traits. The studies offer objective support for a more feminized facial phenotype in gay males that is difficult to explain through cultural or behavioral cues.

AB - This study examines two aspects of the experiences that committed, unmarried same sex couples have with social network members (friends and family members). The study examines how remaining unmarried affected the couples' relationships with social network members and the discursive strategies couples use when discussing their relationship with social network members. Twenty-seven committed, unmarried U.S. same-sex couples were interviewed. Couples described two challenges in their relationships with social network members as a result of not marrying: others perceived their commitment level as lessened because they did not marry, and others supported their relationship less because they did not marry. Couples used four discursive strategies to establish and maintain their family identity when interacting with social network members. Couples' relational experiences and discursive strategies were consistent with previous descriptions of discourse dependent families. PMID- 29185869 TI - Development and Validation of a Novel Integrated Clinical-Genomic Risk Group Classification for Localized Prostate Cancer. AB - Purpose It is clinically challenging to integrate genomic-classifier results that report a numeric risk of recurrence into treatment recommendations for localized prostate cancer, which are founded in the framework of risk groups. We aimed to develop a novel clinical-genomic risk grouping system that can readily be incorporated into treatment guidelines for localized prostate cancer. Materials and Methods Two multicenter cohorts (n = 991) were used for training and validation of the clinical-genomic risk groups, and two additional cohorts (n = 5,937) were used for reclassification analyses. Competing risks analysis was used to estimate the risk of distant metastasis. Time-dependent c-indices were constructed to compare clinicopathologic risk models with the clinical-genomic risk groups. Results With a median follow-up of 8 years for patients in the training cohort, 10-year distant metastasis rates for National Comprehensive Cancer Network (NCCN) low, favorable-intermediate, unfavorable-intermediate, and high-risk were 7.3%, 9.2%, 38.0%, and 39.5%, respectively. In contrast, the three tier clinical-genomic risk groups had 10-year distant metastasis rates of 3.5%, 29.4%, and 54.6%, for low-, intermediate-, and high-risk, respectively, which were consistent in the validation cohort (0%, 25.9%, and 55.2%, respectively). C indices for the clinical-genomic risk grouping system (0.84; 95% CI, 0.61 to 0.93) were improved over NCCN (0.73; 95% CI, 0.60 to 0.86) and Cancer of the Prostate Risk Assessment (0.74; 95% CI, 0.65 to 0.84), and 30% of patients using NCCN low/intermediate/high would be reclassified by the new three-tier system and 67% of patients would be reclassified from NCCN six-tier (very-low- to very-high risk) by the new six-tier system. Conclusion A commercially available genomic classifier in combination with standard clinicopathologic variables can generate a simple-to-use clinical-genomic risk grouping that more accurately identifies patients at low, intermediate, and high risk for metastasis and can be easily incorporated into current guidelines to better risk-stratify patients. PMID- 29185874 TI - "She Finally Smiles ... for Real": Reducing Depressive Symptoms and Bolstering Resilience Through a Camp Intervention for LGBTQ Youth. AB - While summer camps are a recognized evidence-based strategy for building social and emotional skills among youth (U.S. Centers for Disease Control and Prevention [CDC], 2009), no known studies have evaluated the effects of camp programming for LGBTQ youth in the United States. This pilot study evaluates a novel program (Brave Trails) for LGBTQ youth ages 12 to 20, using a pre-post camper survey (N = 56) and a post-camp parent survey (N = 54). Results show campers experienced increases in identity affirmation and hope and a reduction in depressive symptoms. Regression analyses found changes in identity affirmation predicted reductions in depressive symptoms and increases in resilience. Additionally, campers' experience of key camp programming features predicted changes in depressive symptoms. Findings from the parent survey were consistent with camper survey results. Theoretical and practical implications are discussed. PMID- 29185873 TI - In Vivo Determination of Mitochondrial Respiration in 1-Methyl-4-Phenyl-1,2,3,6 Tetrahydropyridine-Treated Zebrafish Reveals the Efficacy of Melatonin in Restoring Mitochondrial Normalcy. AB - Although mitochondria dysfunction is related to multiple diseases, no in vivo studies are available on mitochondrial respiration in animal parkinsonian models. Our aim is to analyze in vivo mitochondrial respiration, which reflects changes in mitochondrial bioenergetics more precisely than in vitro mitochondrial preparations. These experiments can be carried out in zebrafish embryos, which were treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) from 24 to 72 hours postfertilization (hpf). A reduction in electron transfer system capacity, ATP turnover, and increased proton leak were observed at 72 hpf in MPTP treated embryos. These changes were followed by a significant oxidative stress due to inhibition in antioxidative defense and autophagy impairment. After removing MPTP from the treatment at 72 hpf, these bioenergetic deficiencies persisted up to 120 hpf. The administration of melatonin to zebrafish embryos at 72 hpf, when mitochondrial dysfunction is already present, restored the respiratory capacity and ATP production, reduced oxidative stress, and normalized autophagy after 48 h. Melatonin also counteracted mortality and embryonic malformations due to MPTP. Our results confirm for the first time the efficacy of melatonin in restoring parkinsonian phenotypes in animals. PMID- 29185876 TI - Freezing for love: enacting 'responsible' reproductive citizenship through egg freezing. AB - The promise of egg freezing for women's fertility preservation entered feminist debate in connection with medical and commercial control over, and emancipation from, biological reproduction restrictions. In this paper we explore how women negotiate and make sense of the decision to freeze their eggs. Our analysis draws on semi-structured interviews with 16 women from the Midwest and East Coast regions of the USA who froze their eggs. Rather than freezing to balance career choices and 'have it all', the women in this cohort were largely 'freezing for love' and in the hope of having their 'own healthy baby'. This finding extends existing feminist scholarship and challenges bioethical concerns about egg freezing by drawing on the voices of women who freeze their eggs. By viewing egg freezing as neither exclusively liberation nor oppression or financial exploitation, this study casts egg freezing as an enactment of 'responsible' reproductive citizenship that 'anticipates coupledom' and reinforces the genetic relatedness of offspring. PMID- 29185875 TI - Immunization of Mice by Rotavirus NSP4-VP6 Fusion Protein Elicited Stronger Responses Compared to VP6 Alone. AB - Due to the limitations and safety issues of the two currently approved live attenuated rotavirus (RV) vaccines "RotaTeq and Rotarix," studies on nonreplicating sources of RV vaccines and search for proper RV antigens are actively carried out. The adjuvant activity of NSP4 and highly immunogenic properties of RV VP6 protein prompted us to consider the construction of a NSP4112-175-VP6 fusion protein and to assess the anti-VP6 IgG, IgA, and IgG subclass responses induced by Escherichia coli-derived NSP4-VP6 fusion protein compared to that of VP6 protein with/without formulation in Montanide ISA 50V2 (M50) in BALB/c mice. Results indicated to the proper expression of the fused NSP4-VP6 and VP6 proteins in E. coli. Intraperitoneal immunization by M50 formulated NSP4-VP6 fusion protein (M5+NSP4-VP6) induced the highest titration of VP6-specific IgG and IgA responses compared to the other groups. Indeed, the presence of NSP4 resulted to the induction of stronger humoral immune responses against the fused protein compared to that elicited by administration of VP6 protein alone (with/without M50 formulation), implying the adjuvant properties of NSP4 for the fused protein. Moreover, the "M50+NSP4-VP6" formulation induced higher serum IgG2a titers than IgG1 and increased Interferon-gamma levels, despite unchanged interleukin-4 amounts compared to other groups, indicating Th1 oriented responses with a possible role of NSP4. In conclusion, this study further highlights the potentiality of NSP4-VP6 fusion protein as an efficient and cost-effective immunogen in the field of RV vaccine development. PMID- 29185878 TI - Using Problem-solving Therapy to Improve Problem-solving Orientation, Problem solving Skills and Quality of Life in Older Hemodialysis Patients. AB - OBJECTIVES: To determine the effectiveness of Problem-Solving Therapy (PST) in older hemodialysis (HD) patients by assessing changes in health-related quality of life and problem-solving skills. METHODS: 33 HD patients in an outpatient hemodialysis center without active medical and psychiatric illness were enrolled. The intervention group (n = 15) received PST from a licensed social worker for 6 weeks, whereas the control group (n = 18) received usual care treatment. RESULTS: In comparison to the control group, patients receiving PST intervention reported improved perceptions of mental health, were more likely to view their problems with a positive orientation and were more likely to use functional problem solving methods. Furthermore, this group was also more likely to view their overall health, activity limits, social activities and ability to accomplish desired tasks with a more positive mindset. CONCLUSIONS: The results demonstrate that PST may positively impact mental health components of quality of life and problem-solving coping among older HD patients. CLINICAL IMPLICATIONS: PST is an effective, efficient, and easy to implement intervention that can benefit problem solving abilities and mental health-related quality of life in older HD patients. In turn, this will help patients manage their daily living activities related to their medical condition and reduce daily stressors. PMID- 29185877 TI - Evaluation of a Direct Immunofluorescent Assay and/or Conjunctival Cytology for Detection of Canine Distemper Virus Antigen. AB - Canine distemper is a common and potentially lethal multisystemic disease caused by the Canine distemper virus (CDV). We evaluated the diagnostic performance of direct immunofluorescent assay (FA) and cytology to detect CDV antigen in conjunctival cells compared with an established polymerase chain reaction (PCR) detection assay used as a gold standard for CDV diagnosis. Samples were collected from 57 young dogs presenting with central nervous system signs compatible with distemper disease. Exfoliative epithelial cells were collected from the right and left conjunctiva of each animal using nylon-bristled cytobrushes for cytology and cotton swabs for FA and PCR. For the direct FA, samples were stained with anti CDV polyclonal antiserum conjugated to fluorescein isothiocyanate and imaged using a fluorescent microscope. Out of 57 dogs tested, 19 were PCR positive (15 positive in direct FA and 4 positive in cytology, including one that was negative by PCR), whereas 37 dogs were negative in all methods. A good agreement was observed between the FA and PCR, with a kappa-value of 0.833 (95% CI: 0.678 0.989). Meanwhile, there was poor agreement between cytology and PCR (kappa-value of 0.164; 95% CI: -0.045 to 0.373) and a fair agreement between FA and cytology (kappa-value of 0.231; 95% CI: -0.026 to 0.487). Our results indicated a poor performance of cytology for the detection of CDV antigen. In contrast, FA is a 100% specific and an adequately sensitive assay (sensitivity: 78.95%, negative likelihood ratio: 0.21, 95% CI: 0.09-0.50) for antemortem diagnosis of canine distemper. PMID- 29185879 TI - Early Conceptual Understanding of Cardinality Predicts Superior School-Entry Number-System Knowledge. AB - We demonstrate a link between preschoolers' quantitative competencies and their school-entry knowledge of the relations among numbers (number-system knowledge). The quantitative competencies of 141 children (69 boys) were assessed at the beginning of preschool and throughout the next 2 years of preschool, as was their mathematics and reading achievement at the end of kindergarten and their number system knowledge at the beginning of first grade. A combination of Bayes analyses and standard regressions revealed that the age at which the children had the conceptual insight that number words represent specific quantities (cardinal value) was strongly related to their later number-system knowledge and was more consistently related to broader mathematics than to reading achievement, controlling for intelligence, executive function, and parental education levels. The key implication is that it is not simply knowledge of cardinal value but the age of acquisition of this principle that is central to later mathematical development and school readiness.

AB - This work aimed to investigate the effectiveness of ozone in degradation of polyoxymethylene (POM) effluent in a rotating packed bed (RPB) (O3-RPB system). The degradation efficiency was evaluated in terms of chemical oxygen demand (COD), 5-day biological oxygen demand (BOD5) and BOD5/COD under various operating conditions. Pilot experiments comprising the O3-RPB unit coupled with a biological contact oxidation unit were also carried out. The COD removal rates in the pilot process increased markedly to about 70-85% compared to about 40% in the original treatment process, which is the tertiary aerobic treatment in the plant, confirming that the O3-RPB system is very efficient in improving the biodegradability of the POM effluent. PMID- 29185886 TI - Fish Oil Suppresses Body Fat Accumulation in Zebrafish. AB - Zebrafish is an often used model of vertebrate lipid metabolism. In this article, we examined the effects of diets rich in fish oil, a dietary fat that has been shown to have antiobesity effects in mammals, or lard on body fat accumulation in zebrafish. Adult female zebrafish were fed a high-fat diet containing 20% (w/w) fish oil or lard for 4 weeks. Fish in the fish oil diet group had less body fat accumulation compared with those in the lard diet group. In the intestine, expression of genes for the alpha (hadhaa) and beta (hadhb) subunits of the beta oxidation enzyme hydroxyacyl-Coenzyme A dehydrogenase/3-ketoacyl-Coenzyme A thiolase/enoyl-Coenzyme A hydratase was significantly increased in the fish oil diet group compared with the lard diet group (p < 0.05). In the liver, expression of the gene for fatty acid synthase (fasn) was significantly decreased in the fish oil diet group compared with the lard diet group (p < 0.05). These results suggest that the mechanisms underlying the antiobesity effect of fish oil are similar in zebrafish and mammals.

AB - Conduct disorder (CD) symptoms cooccur at high rates with illicit drug use in juvenile justice involved youth, which results in poorer outcomes; however, research has not identified where best to intervene in this relationship, limiting the identification of modifiable risk factors to reduce negative effects of CD symptoms. Two mediation models were examined to investigate the potential for CD symptoms to influence a reciprocal relationship between illicit drug use and positive drug attitudes, controlling for age, gender, and race. Data were examined for 245 juvenile justice involved youth (mean age = 15.46, SD = 1.30, range 12-18, 64.9% Black, 80.4% male) who completed court-ordered psychological assessments. Findings indicate: (1) Positive attitudes toward illicit drug use significantly mediated the relationship between CD symptoms and illicit drug use (beta = 0.16, CI 0.09-0.27; test for indirect effect z = 4.17, p < .001) and (2) illicit drug use significantly mediated the relationship between CD symptoms and positive attitudes toward illicit drug use (beta = 0.20, CI 0.12-0.32; test for indirect effect z = 4.87, p < .001). Overall, the present study suggests that CD symptoms impart risk for illicit drug use both indirectly, through more positive attitudes toward illicit drug use, and directly, which further strengthens positive attitudes toward illicit drug use.

AB - Diagnostic imaging technology is becoming more advanced and widely available to veterinary patients with the growing popularity of veterinary-specific computed tomography (CT) and magnetic resonance imaging (MRI). Veterinary students must, therefore, be familiar with these technologies and understand the importance of sound anatomic knowledge for interpretation of the resultant images. Anatomy teaching relies heavily on visual perception of structures and their function. In addition, visual spatial ability (VSA) positively correlates with anatomy test scores. We sought to assess the impact of including more diagnostic imaging, particularly CT/MRI, in the teaching of veterinary anatomy on the students' perceived level of usefulness and ease of understanding content. Finally, we investigated survey answers' relationship to the students' inherent baseline VSA, measured by a standard Mental Rotations Test. Students viewed diagnostic imaging as a useful inclusion that provided clear links to clinical relevance, thus improving the students' perceived benefits in its use. Use of CT and MRI images was not viewed as more beneficial, more relevant, or more useful than the use of radiographs. Furthermore, students felt that the usefulness of CT/MRI inclusion was mitigated by the lack of prior formal instruction on the basics of CT/MRI image generation and interpretation. To be of significantly greater use, addition of learning resources labeling relevant anatomy in tomographical images would improve utility of this novel teaching resource. The present study failed to find any correlation between student perceptions of diagnostic imaging in anatomy teaching and their VSA.

AB - Three milestone educational planning initiatives engaged the veterinary medical profession in the United States and Canada between 1987 and 2011, namely the Pew National Veterinary Education Program, the Foresight Project, and the North American Veterinary Medical Education Consortium. In a quantitative study, we investigated the impact of these initiatives on veterinary medical education through a survey of academic leaders (deans, previous deans, and associate deans for academics from veterinary medical schools that are members of the Association of American Veterinary Medical Colleges) to assess their perspectives on the initiatives and eight recommendations that were common to all three initiatives. Two of the recommendations have in effect been implemented: enable students to elect in-depth instruction and experience within a practice theme or discipline area (tracking), and increase the number of graduating veterinarians. For three of the recommendations, awareness of the issues has increased but substantial progress has not been made: promote diversity in the veterinary profession, develop a plan to reduce student debt, and develop a North American strategic plan. Lastly, three recommendations have not been accomplished: emphasize use of information more than fact recall, share educational resources to enable a cost effective education, and standardize core admissions requirements. The educational planning initiatives did provide collaborative opportunities to discuss and determine what needs to change within veterinary medical education. Future initiatives should explore how to avoid and overcome obstacles to successful implementation.

AB - To optimize bovine pregnancy diagnosis (PD) training, factors influencing student performance were investigated. The objective was to determine whether training method, gender, background (farm, urban, or mixed), previous experience in bovine PD, and current career interest influenced the accuracy of bovine PD by trans rectal palpation (TRP). Fourth-year (of a 6-year program) veterinary students (n=138) received one PD training session in groups using either simulator training on Breed'n Betsy (BB) or training on live cows (C). Students completed a questionnaire on gender, background, and career interest. Students' PD accuracy (pregnancy status and stage) was determined after training when each student palpated six cows with known pregnancy status. Students' accuracy in determining pregnancy status was measured as sensitivity and specificity (the ability to correctly identify the presence and absence of pregnancy respectively). Factors that influenced overall accuracy with a higher student sensitivity of bovine PD by TRP were training method, farming background, an interest in a mixed animal career, and stage of gestation. Gender of students and previous experience in bovine PD did not have an influence. Training on BB simulators was associated with lower student sensitivity for pregnancy detection in cows <6 months pregnant. Student sensitivity for pregnancy detection in cows >6 months pregnant was similar for training on BB simulators and live cows. No evaluated factors were significantly associated with specificity of PD. Teaching efforts focusing on specificity of PD and repeated simulator-based training in conjunction with live cow exposure are recommended.

AB - INTRODUCTION: Pharmacological treatment of insomnia in patients with addictions has been hardly investigated and there are few researches about it in an inpatient detoxification. The aim of this study was to describe the outcomes of the pharmacological treatment of insomnia in SUD patients admitted to a detoxification unit in Spain, with a focus on the primary substance of abuse and co-occurring mental disorders. METHODS: A quasi-experimental study was conducted in 481 addicted in patients, who were admitted for substances detoxification in Vall d'Hebron University Hospital, Barcelona, Spain, from 2010 to 2015. The patients underwent systematic evaluation of axes I and II psychiatric disorders (SCID-I, SCID-II, and CAADID). Insomnia was evaluated using a night time sleep log. Substance-dependent patients, who had insomnia during hospital detoxification, received a psychotropic medication with hypnotic effect, keeping the regular clinical practice without randomization. RESULTS: At discharge, insomnia was considered to have been alleviated in 63.8% (n = 204) of patients while 36.2% (n = 116) of patients remained with insomnia disturbances. Comparing hypnotic treatments it was observed that mirtazapine and clotiapine were the treatment that corrected the insomnia more frequently. DISCUSSION: Since insomnia is not corrected in all patients, it should be further investigated in medications with hypnotic purpose. Based on the results of this work, randomized clinical trials might be proposed. PMID- 29185896 TI - Impact of Expert Commentary and Student Reflection on Veterinary Clinical Decision-Making Skills in an Innovative Electronic-Learning Case-Based Platform. AB - One challenge in veterinary education is bridging the divide between the nature of classroom examples (well-defined problem solving) and real world situations (ill-defined problem solving). Solving the latter often relies on experiential knowledge, which is difficult to impart to inexperienced students. A multidisciplinary team including veterinary specialists and learning scientists developed an interactive, e-learning case-based module in which students made critical decisions at five specific points (Decision Points [DPs]). After committing to each decision (Original Answers), students reflected on the thought processes of experts making similar decisions, and were allowed to revise their decisions (Revised Answers); both sets of answers were scored. In Phase I, performance of students trained using the module (E-Learning Group) and by lecture (Traditional Group) was compared on the course final examination. There was no difference in performance between the groups, suggesting that the e learning module was as effective as traditional lecture for content delivery. In Phase II, differences between Original Answers and Revised Answers were evaluated for a larger group of students, all of whom used the module as the sole method of instruction. There was a significant improvement in scores between Original and Revised Answers for four out of five DPs (DP1, p =.004; DP2, p =.04; DP4, p <.001; DP5, p <.001). The authors conclude that the ability to rehearse clinical decision making through this tool, without direct individual feedback from an instructor, may facilitate students' transition from problem solving in a well structured classroom setting to an ill-structured clinical setting. PMID- 29185898 TI - Both enantiomers of 6'-Isoneplanocin. AB - Both enantiomers of the isomer of neplanocin where the C-4' hydroxymethyl has been displaced to the 6'-position (that is, 6'-isoneplanocin) have been prepared in 5 steps from known, protected iodocyclopentenones. Both products were evaluated against a number of DNA and RNA viruses and found to be inactive. This observation is suggested to be due to the displacement of the C-4' hydroxymethyl of neplanocin (in the D-like form) away from the lysine425 of S adenosylhomocysteine hydrolase, which is important for inhibition by neplanocin and, in turn, its antiviral activity. PMID- 29185899 TI - Vaccination coverage and factors associated with adherence to the vaccination schedule in young children of a rural area in Burkina Faso. AB - BACKGROUND: Vaccination is an important tool for reducing infectious disease morbidity and mortality. In the past, less than 80% of children 12-23 months of age were fully immunized in Burkina Faso. OBJECTIVES: To describe coverage and assess factors associated with adherence to the vaccination schedule in rural area Burkina Faso. METHODS: The study population was extracted from the Nouna Health and Demographic surveillance system cohort. Data from four rounds of interviews conducted between November 2012 and June 2014 were considered. This study included 4016 children aged 12-23 months. We assessed the effects of several background factors, including sex, factors reflecting access to health care (residence, place of birth), and maternal factors (age, education, marital status), on being fully immunized defined as having received Bacillus Calmette Guerin (BCG), three doses of diphtheria-tetanus-pertussis and oral polio vaccine, and measles vaccine by 12 months of age. The associations were studied using binomial regression to derive prevalence ratios (PRs) in univariate and multivariate regression models. RESULTS: The full vaccination coverage increased significantly over time (72% in 2012, 79% in 2013, and 81% in 2014, p = 0.003), and the coverage was significantly lower in urban than in rural areas (PR 0.84; 0.80-0.89). Vaccination coverage was neither influenced by sex nor influenced by place of birth or by maternal factors. CONCLUSION: The study documented a further improvement in full vaccination coverage in Burkina Faso in recent years and better vaccination coverage in rural than in urban areas. The organization of healthcare systems with systematic outreach activities in the rural areas may explain the difference between rural and urban areas.

AB - In this study, an attempt has been made to study the interaction of a Zn(II) complex containing an antibiotic drug, ciprofloxacin, with calf thymus DNA using spectroscopic methods. It was found that Zn(II) complex could bind with DNA via intercalation mode as evidenced by: hyperchromism in UV-Vis spectrum; these spectral characteristics suggest that the Zn(II) complex interacts with DNA most likely through a mode that involves a stacking interaction between the aromatic chromophore and the base pairs of DNA. DNA binding constant (Kb = 1.4 * 104 M-1) from spectrophotometric studies of the interaction of Zn(II) complex with DNA is comparable to those of some DNA intercalative polypyridyl Ru(II) complexes 1.0 4.8 * 104 M-1. CD study showed stabilization of the right-handed B form of DNA in the presence of Zn(II) complex as observed for the classical intercalator methylene blue. Thermodynamic parameters (DeltaH < 0 and DeltaS < 0) indicated that hydrogen bond and Van der Waals play main roles in this binding prose. Competitive fluorimetric studies with methylene blue (MB) dye have shown that Zn(II) complex exhibits the ability of this complex to displace with DNA-MB, indicating that it binds to DNA in strong competition with MB for the intercalation. PMID- 29185901 TI - Identification of Distant Metastatic Disease in Uterine Cervical and Endometrial Cancers with FDG PET/CT: Analysis from the ACRIN 6671/GOG 0233 Multicenter Trial. AB - Purpose To assess the accuracy of staging positron emission tomography (PET)/computed tomography (CT) in detecting distant metastasis in patients with local-regionally advanced cervical and high-risk endometrial cancer in the clinical trial by the American College of Radiology Imaging Network (ACRIN) and the Gynecology Oncology Group (GOG) (ACRIN 6671/GOG 0233) and to compare central and institutional reader performance. Materials and Methods In this prospective multicenter trial, PET/CT and clinical data were reviewed for patients enrolled in ACRIN 6671/GOG 0233. Two central readers, blinded to site read and reference standard, reviewed PET/CT images for distant metastasis. Central review was then compared with institutional point-of-care interpretation. Reference standard was pathologic and imaging follow-up. Test performance for central and site reviews of PET/CT images was calculated and receiver operating characteristic analysis was performed. Generalized estimating equations and nonparametric bootstrap procedure for clustered data were used to assess statistical significance. Results There were 153 patients with cervical cancer and 203 patients with endometrial cancer enrolled at 28 sites. Overall prevalence of distant metastasis was 13.7% (21 of 153) for cervical cancer and 11.8% (24 of 203) for endometrial cancer. Central reader PET/CT interpretation demonstrated sensitivity, specificity, positive predictive value (PPV), and negative predictive value of 54.8%, 97.7%, 79.3%, and 93.1% for cervical cancer metastasis versus 64.6%, 98.6%, 86.1%, and 95.4% for endometrial cancer, respectively. By comparison, local institutional review demonstrated sensitivity, specificity, PPV, and negative predictive value of 47.6%, 93.9%, 55.6%, and 91.9% for cervical cancer metastasis and 66.7%, 93.9%, 59.3%, and 95.5% for endometrial cancer, respectively. For central readers, the specificity and PPV of PET/CT detection of cervical and endometrial cancer metastases were all significantly higher compared with that of local institutional review (P < .05). Central reader area under the receiver operating characteristic curve (AUC) values were 0.78 and 0.89 for cervical and endometrial cancer, respectively; these were not significantly different from local institutional AUC values (0.75 and 0.84, respectively; P > .05 for both). Conclusion FDG PET/CT demonstrates high specificity and PPV for detecting distant metastasis in cervical and endometrial cancer and should be included in the staging evaluation. Blinded central review of imaging provides improved specificity and PPV for the detection of metastases and should be considered for future oncologic imaging clinical trials. (c) RSNA, 2017.

AB - The landscape of American health care is changing under the weight of new knowledge that health care workers-physicians, nurses, and so on-are abusing the drugs that they use within health care. In this article, the author uses ethnographic data (including his own work in American pharmacies over the past two decades) to contextualize how health care's drug abuse epidemic is racially coded to ignore the fact that White Americans are the primary drug abusers-what he calls "redpilling." In pointing out the racial contexts of health care's drug abuse, the author asks whether our national "war on drugs" ought to be recast to see how White racial privilege-the privilege of White Americans to comfortably perform certain actions (and get away with them if they are illegal or morally wrong)-mandates that we move the lens of drug policy from ghettos and ethnic communities to American health care where we have been historically positioned to not identify White American health care workers who work while high.

AB - Purpose To determine the accuracy of dual-energy computed tomographic (CT) quantitation in a phantom system comparing fast kilovolt peak-switching, dual source, split-filter, sequential-scanning, and dual-layer detector systems. Materials and Methods A large elliptical phantom containing iodine (2, 5, and 15 mg/mL), simulated contrast material-enhanced blood, and soft-tissue inserts with known elemental compositions was scanned three to five times with seven dual energy CT systems and a total of 10 kilovolt peak settings. Monochromatic images (50, 70, and 140 keV) and iodine concentration images were created. Mean iodine concentration and monochromatic attenuation for each insert and reconstruction energy level were recorded. Measurement bias was assessed by using the sum of the mean signed errors measured across relevant inserts for each monochromatic energy level and iodine concentration. Iodine and monochromatic errors were assessed by using the root sum of the squared error of all measurements. Results At least one acquisition paradigm per scanner had iodine biases (range, -2.6 to 1.5 mg/mL) with significant differences from zero. There were no significant differences in iodine error (range, 0.44-1.70 mg/mL) among the top five acquisition paradigms (one fast kilovolt peak switching, three dual source, and one sequential scanning). Monochromatic bias was smallest for 70 keV (-12.7 to 15.8 HU) and largest for 50 keV (-80.6 to 35.2 HU). There were no significant differences in monochromatic error (range, 11.4-52.0 HU) among the top three acquisition paradigms (one dual source and two fast kilovolt peak switching). The lowest accuracy for both measures was with a split-filter system. Conclusion Iodine and monochromatic accuracy varies among systems, but dual-source and fast kilovolt switching generally provided the most accurate results in a large phantom.

AB - Cryptosporidium is a parasitic protozoon with a wide range of vertebrate hosts. Cryptosporidiosis has been reported from numerous countries, including Iran. Molecular identification can be applied to characterize Cryptosporidium, of which there are over 30 species and 50 genotypes. Herein, we report the genetic diversity of Cryptosporidium spp. in Iranian dogs for the first time based on 18S ribosomal RNA gene sequencing. One hundred forty fecal samples of herd dogs were collected from Isfahan, central Iran. The samples were concentrated using sucrose flotation and subjected to Kinyoun staining. DNA extraction of positive samples was performed, and molecular diagnosis was carried out using highly specific seminested PCR for the characterization of Cryptosporidium species. Finally, sequencing and DNA analysis were performed to identify Cryptosporidium species. A total of 2.14% of herd dogs were positive for cryptosporidiosis in both microscopy and molecular methods. In all cases, the causative agent was identified as Cryptosporidium parvum. Dogs associated with positive samples had been in close relationship with livestock. Cryptosporidiosis in the herd dogs in Isfahan could be due to their close contact with animals, particularly cattle and sheep. Given that dogs with cryptosporidiosis lack clinical symptoms, they are a potential source of zoonotic transmission of this disease as they are companion animals for humans. Dogs with cryptosporidiosis are a potential source of the zoonotic transmission of this disease.

AB - Pichia pastoris is considered as one of the prominent host extensively used as a platform for heterologous protein production. In the present study, the growth inhibition kinetics of recombinant P. pastoris expressing human interferon gamma was studied under different initial substrate concentrations of gluconate (10-100 g L-1) and methanol (2-50 g L-1) in modified FM22 medium. The highest specific growth rate of 0.0206 and 0.019 hr-1 was observed at 60 g L-1 of gluconate and 10 g L-1 of methanol, respectively. Various three- and four-parametric Monod-variant models were chosen to analyze the inhibition kinetics. The model parameters as well as goodness of fit were estimated using nonlinear regression analysis. The three-parameter Haldane model was found to be best fit for both gluconate (R2 = 0.95) and methanol substrate (R2 = 0.96). The parameter sensitivity analysis revealed that umax, Ki, and Ks are the most sensitive parameters for both methanol and gluconate. Different substrate inhibition models were fitted to the growth kinetic data and the additive form of double Webb model was found to be the best to explain the growth kinetics of recombinant P. pastoris.

AB - In the cell, nearly 40% of the volume is occupied by macromolecular crowding agents and smaller osmolytes accumulate in response to environmental stresses. Of particular interest is the influence of osmolytes on the transition of the right handed B-DNA to the left-handed Z-DNA. Due to the correlation between Z-DNA formation potential and regions of active transcription, Z-DNA is believed to serve a vital role in the transcription process, and changes in osmolyte concentration may influence transcription as a part of the stress response. We utilized circular dichroism spectroscopy to monitor changes in conformation of DNA duplexes containing a full-turn of Z-DNA in the presence and absence of PEG 200. We used PEG 200 as a model neutral cosolute. Sodium ion titrations revealed that PEG 200 influenced the folding of Z-DNA compared to dilute solution conditions by decreasing the free energy of folding, increasing folding cooperativity, and decreasing the in vitro [Na+] and Deltan required for folding for all sequences tested, even those that included 40% CA steps instead of the classic CG repeats. Moreover, the presence of 40% PEG 200 induced the Z-form conformation in sequences that would not fully adopt the Z-form structure even in 5 M NaCl. These results suggest that osmolytes may play a significant role in supporting the transient formation of Z-DNA in vivo, and that sequences containing a significant amounts of CA instead of CG repeats may more favorably adopt the Z-conformation as a part of binding and regulatory processes than had been previously considered. PMID- 29185910 TI - A Critical Analysis and Applied Intersectionality Framework with Intercultural Queer Couples. AB - Intercultural queer couples are growing at an extensive rate in the United States, exemplifying diversity across multiple dimensions (e.g., race, ethnicity, sexuality, affectional identity, gender identity) while experiencing multiple converging forms of oppression (e.g., racism, heterosexism, genderism). Given the dearth of conceptual and empirical literature that unifies both dimensions related to intercultural and queer, applied practices and research contend with a unilateral approach focusing exclusively on either intercultural or queer couples. Intersectionality theory has revolutionized critical scholarship to determine overlapping forms of oppression, decenter hegemonic structures of power relations and social contexts, and enact a social justice agenda. This article addresses the following aims: (1) an overview of the gaps eliciting unilateral approaches to intercultural queer couples; (2) an illustration of intersectionality's theoretical underpinnings as a critical approach; and (3) applications for insights in practices and research with intercultural queer couples.

AB - OBJECTIVES: Health and social care services are increasingly reliant on informal caregivers to provide long-term support to stroke survivors. However, caregiving is associated with elevated levels of depression and anxiety in the caregiver that may also negatively impact stroke survivor recovery. This qualitative study aims to understand the specific difficulties experienced by caregivers experiencing elevated symptoms of anxiety and depression. METHODS: Nineteen semi structured interviews were conducted with caregivers experiencing elevated levels of depression and anxiety, with a thematic analysis approach adopted for analysis. RESULTS: Analysis revealed three main themes: Difficulties adapting to the caring role; Uncertainty; and Lack of support. CONCLUSIONS: Caregivers experienced significant difficulties adapting to changes and losses associated with becoming a caregiver, such as giving up roles and goals of importance and value. Such difficulties persisted into the long-term and were coupled with feelings of hopelessness and worry. Difficulties were further exacerbated by social isolation, lack of information and poor long-term health and social care support. CLINICAL IMPLICATIONS: A greater understanding of difficulties experienced by depressed and anxious caregivers may inform the development of psychological support targeting difficulties unique to the caring role. Improving caregiver mental health may also result in health benefits for stroke survivors themselves.

AB - Within the past decade, microbiologists have moved from detecting single antibiotic resistance genes (ARGs) to detecting all known resistance genes within a sample due to advances in next generation sequencing. This has provided a wealth of data on the variation and relative abundances of ARGs present in a total bacterial population. However, to use these data in terms of therapy or risk to patients, they must be analyzed in the context of the background microbiome. Using a quantitative PCR ARG chip and 16S rRNA amplicon sequencing, we have sought to identify the ARGs and bacteria present in a fecal sample of a healthy adult using genomic tools. Of the 42 ARGs detected, 12 fitted into the ResCon1 category of ARGs: cfxA, cphA, bacA, sul3, aadE, blaTEM, aphA1, aphA3, aph(2')-Id, aacA/aphd, catA1, and vanC. Therefore, we describe these 12 genes as the core resistome of this person's fecal microbiome and the remaining 30 ARGs as descriptors of the microbial population within the fecal microbiome. The dominant phyla and genera agree with those previously detected in the greatest abundances in fecal samples of healthy humans. The majority of the ARGs detected were associated with the presence of specific bacterial taxa, which were confirmed using microbiome analysis. We acknowledge the limitations of the data in the context of the limited sample set. However, the principle of combining qPCR and microbiome analysis was shown to be helpful to identify the association of the ARGs with specific taxa. PMID- 29185916 TI - Drug-Drug Interactions in Cocaine-users and their Clinical Implications. AB - BACKGROUND: Drug-Drug Interactions (DDIs) represent a common problem in clinical practice during drug treatments. DDIs can both induce the development of adverse drug reactions or reduce the clinical efficacy of each drug. OBJECTIVES: The main objective of this review was to analyze the pharmacokinetic and pharmacodynamic DDIs in cocaine consumers, focusing the interest on their clinical implications. METHODS: The PubMed, Embase and Cochrane library databases were searched for articles published until January 10, 2017. Secondary search included articles cited in reference lists identified by the primary search. Papers were deemed eligible if they included any form of words: "adverse drug reaction", "drug interactions", "poly-therapy", "cocaine", "systemic diseases". RESULTS: In this review, the nodal points treated concern: i) cocaine biochemical metabolism described for both, inactive benzoylecgonine and ecgonine methyl esters and norcocaine active metabolites. We provided evidences of concepts deriving from rat/mice experimental studies speculating a translation approach to human in order to treat cocaine overdose. ii) Drug-drug interactions, which come out from clinical evidences as the case of CYP450 family enzyme inhibitors or inductors modulating cocaine toxicity. Particularly, we highlighted the lack of knowledge concerning cocaine and CYP3A4 inhibitors (such as ketoconazole, nefazodone, erythromycin, and clarithromycin). We recorded the worst association of cocaine and beta-blockers by direct and indirect action, particularly at postsynaptic levels on dopamine and norepinephrine reuptake, sympathetic activation and increase of heart rate, blood pressure and cardiovascular toxicity. Cocaine also induces increase in serotonin synaptic activity leading to the development of a serotoninergic syndrome when used with drugs that affect serotonin pathway. Genetic (i.e. glutathione peroxidase-1 deficiency) and epigenetic factors (i.e. microRNAs) may be involved in drug-drug interactions in cocaine-users are also being introduced. CONCLUSION: DDIs represent an important potential complication in cocaine users in clinical setting. The knowledge of DDIs can also be used to select treatments for patients, thus optimizing clinical response and minimizing toxicity. PMID- 29185919 TI - COLORFUL ENGINEERING.

PMID- 29185920 TI - A TB40/E-derived human cytomegalovirus genome with an intact US-gene region and a self-excisable BAC cassette for immunological research. AB - For immunological research on the human cytomegalovirus (HCMV), a virus that combines the broad cell tropism of clinical isolates, efficient replication in cell culture, the complete set of MHC-I modulator genes, and suitability for genetic engineering is desired. Here, we aimed to generate a genetically complete derivative of HCMV strain TB40/E as a bacterial artificial chromosome (BAC) with a self-excisable BAC cassette. The BAC cassette was inserted into the US2-US6 gene region (yielding TB40-BACKL7), relocated into the UL73/UL74 region with modifications that favor excision of the BAC cassette during replication in fibroblasts, and finally the US2-US6 region was restored, resulting in BAC clone TB40-BACKL7-SE When this BAC clone was transfected into fibroblasts at efficiencies >0.1%, replicating virus that had lost the BAC cassette appeared within 2 weeks after transfection, grew to high titers, and displayed the broad tropism of the parental virus. The degree of MHC-I down-regulation by this virus was consistent with functional restoration of US2-US6. To enable detection of infected cells by flow cytometry, an enhanced green fluorescent protein (EGFP) expression cassette was inserted downstream of US34A, yielding the fluorescent virus RV-TB40-BACKL7-SE-EGFP. PMID- 29185921 TI - Mouse Behavior Tracker: An economical method for tracking behavior in home cages. AB - Analysis of mouse behavior often requires expensive equipment and transfer of the mice to new test environments, which could trigger confounding behavior alterations. Here, we describe a system for tracking mouse behavior in home cages using a low-cost USB webcam and free software (Fiji and wrMTrck). We demonstrate the effectiveness of this method by tracking differences in distance traveled, speed, and movement tracks between wild-type mice and amyotrophic lateral sclerosis (ALS) model mice (SOD1G93A). PMID- 29185922 TI - Incorporation of unique molecular identifiers in TruSeq adapters improves the accuracy of quantitative sequencing. AB - Quantitative analysis of next-generation sequencing (NGS) data requires discriminating duplicate reads generated by PCR from identical molecules that are of unique origin. Typically, PCR duplicates are identified as sequence reads that align to the same genomic coordinates using reference-based alignment. However, identical molecules can be independently generated during library preparation. Misidentification of these molecules as PCR duplicates can introduce unforeseen biases during analyses. Here, we developed a cost-effective sequencing adapter design by modifying Illumina TruSeq adapters to incorporate a unique molecular identifier (UMI) while maintaining the capacity to undertake multiplexed, single index sequencing. Incorporation of UMIs into TruSeq adapters (TrUMIseq adapters) enables identification of bona fide PCR duplicates as identically mapped reads with identical UMIs. Using TrUMIseq adapters, we show that accurate removal of PCR duplicates results in improved accuracy of both allele frequency (AF) estimation in heterogeneous populations using DNA sequencing and gene expression quantification using RNA-Seq. PMID- 29185923 TI - ReViMS: Software tool for estimating the volumes of 3-D multicellular spheroids imaged using a light sheet fluorescence microscope. AB - Cancer 3-D spheroids are widely used to test drugs and radiotherapy treatments. These 3-D cell clusters range from tens to hundreds of micrometers in size, with shapes that typically differ from a perfect sphere. Change in spheroid volume is one of the most important parameters for evaluating treatment efficacy, and using light sheet fluorescence microscopes (LSFM), optical sections of samples in that size range can be obtained. However, there remains a lack of validated methods for quantifying the volumes of 3-D multicellular aggregates. Here, we present Reconstruction and Visualization from Multiple Sections (ReViMS), an open-source, user-friendly software for automatically segmenting z-stacks of fluorescence images and estimating the volumes of 3-D multicellular spheroids. To assess the precision and accuracy of the volume estimates obtained with ReViMS, we used several cancer spheroids imaged with LSFM. Both the precision and accuracy were >95%, demonstrating the effectiveness of ReViMS. PMID- 29185924 TI - Protocol for adhesion and immunostaining of lymphocytes and other non-adherent cells in culture. AB - Immunostaining of non-adherent cells is commonly performed after adhesion of cells onto microscope slides either using cytocentrifugation or with the help of charged coating substrates. These techniques, however, require either specialized equipment or significant preparation time. Here, we describe a method for immunofluorescent staining of lymphocytes within multi-well culture plates, where cells suspended in phosphate buffered saline (PBS) are adhered to either the plastic well bottom or glass coverslips by gravity sedimentation. This technique requires only common laboratory materials, no coating steps, and allows for densely adherent cell coverage with 1 * 106 cells. Our data show that suspension of cells in PBS, but not serum-containing growth medium, allows for adhesion to plastic or glass after 30 min of gravity sedimentation. We show that this method is applicable for immunofluorescent staining of both primary human lymphocytes and immortalized lymphoma cells, and that it preserves cell morphology. PMID- 29185928 TI - Dietary intake, nutritional status and mental wellbeing of homeless adults in Reading, UK. AB - Malnutrition has been reported in the homeless, yet the specific nutritional issues faced by each homeless community are unclear. This is in part due to nutrient intake often being compared with dietary reference values as opposed to a comparative housed population. In addition, the complex interplay between nutrient intake, reward mediated behaviour and mental illness is frequently overlooked. This study aimed to compare the dietary intake, nutritional status and mental wellbeing of homeless and housed adults. Homeless (n 75) and matched housed (n 75) adults were recruited from Reading (UK). Nutrient intake was determined using the European Prospective Investigation into Cancer and Nutrition Norfolk FFQ. The Patient Health Questionnaire: Somatic Anxiety Depressive Symptoms (PHQ-SADS) assessed for signs of mental illness. Demographic, behavioural and physiological information was collected using closed-ended questions and anthropometric measurements. Overall, dietary intake was poorer in homeless adults who reported higher intakes of salt (8.0 v. 6.4 g, P=0.017), SFA (14.6 v. 13.0 %, P=0.002) and alcohol (5.3 v. 1.9 %, P<0.001) and lower intakes of fibre (13.4 v. 16.3 g, P<0.001), vitamin C (79 v. 109 mg, P<0.001) and fruit (96 v. 260 g, P<0.001) than housed. Smoking, substance misuse and PHQ-SADS scores were also higher in the homeless (P<0.001). Within the homeless population, street homeless (n 24) had lower SFA (13.7 v.15.0 %, P=0.010), Ca (858 v. 1032 mg, P=0.027) and milk intakes (295 v. 449 g, P=0.001) than hostel residents (n 51), which may reflect the issues with food storage. This study highlights the disparity between nutritional status in homeless and housed populations and the need for dietary intervention in the homeless community.

AB - Our previous study demonstrated that supplemental psyllium fibre increased cytoprotective heat-shock protein (Hsp) 25 levels in the intestinal cells of mice. Here, we examined the effect of psyllium fibre on colonic gene and protein expression and faecal microbiota in normal and colitic mice to improve the understanding of the preventive role of the supplement. DNA microarray analysis revealed that a 10 % psyllium fibre diet administered for 5 d up-regulated eleven extracellular matrix (ECM)-associated genes, including collagens and fibronectins, in normal mice. Acute colitis was induced using dextran sodium sulphate (DSS) in mice that were administered a pre-feeding 5 to 10 % psyllium fibre diet for 5 d. Psyllium fibre partially ameliorated or resolved the DSS induced colon damage and inflammation characterised by body weight loss, colon shortening, increased levels of pro-inflammatory cytokines and decreased tight junction protein expression in the colon. Analysis of faecal microbiota using denaturing gradient gel electrophoresis of the PCR-amplified 16S rRNA gene demonstrated that psyllium fibre affected the colonic microbiota. Intestinal permeability was evaluated by growing intestinal Caco-2 cell monolayers on membrane filter supports coated with or without fibronectin and collagen. Cells grown on collagen and fibronectin coating showed higher transepithelial electrical resistance, indicating a strengthening of barrier integrity. Therefore, increased Hsp25 levels and modification of colonic ECM contribute to the observed psyllium-mediated protection against DSS-induced colitis. Furthermore, ECM modification appears to play a role in the strengthening of the colon barrier. In conclusion, psyllium fibre may be useful in the prevention of intestinal inflammatory diseases.

AB - The aim of this study was to evaluate the impact of a non-restrictive satiating diet in men displaying various degrees of satiety efficiency. In all, sixty-nine obese men aged 41.5 (sd 5.7) years were randomly assigned to a control (10-15, 55 60 and 30 % energy as protein, carbohydrate and lipid, respectively; n 34) or satiating (20-25, 45-50 and 30-35 % energy as protein, carbohydrate and lipid, respectively; n 35) diet for 16 weeks, and were classified as having a low (LSP) or high (HSP) satiety phenotype. Both diets were consumed ad libitum. Changes in body weight, BMI, percent fat mass, waist circumference, satiety responsiveness and eating behaviour traits were assessed following the intervention. Dropout rates were higher in the control diet (44.1 %) compared with the satiating diet (8.6 %). Decreases in body weight, BMI and waist circumference were significant in both groups, yet HSP individuals lost more body weight than LSP individuals (P=0.048). Decreases in % fat mass were greater in the satiating diet (LSP: -2.1 (sd 2.1) %; P<0.01 and HSP: -3.0 (sd 2.5) %; P<0.001) compared with the control diet (LSP: -1.1 (sd 2.5) % and HSP: -1.3 (sd 2.6) %) (P=0.034). Satiety responsiveness was markedly improved in the satiating diet, whereas no significant changes were observed in the control group. Changes in dietary restraint (+3.3 (sd 2.9) to +7.2 (sd 5.5)), flexible control (+0.9 (sd 1.4) to +2.3 (sd 2.7)), rigid control (+2.2 (sd 1.5) to +2.5 (sd 2.8)), disinhibition ( 2.8 (sd 3.7) to -3.2 (sd 2.6)) and susceptibility to hunger (-2.7 (sd 4.1) to 4.6 (sd 3.9)) were similar between the diets. Compared with the control diet, the satiating diet favoured adherence, decreased % fat mass and improved satiety responsiveness in both HSP and LSP individuals. PMID- 29185930 TI - Impact of sourdough fermentation on appetite and postprandial metabolic responses - a randomised cross-over trial with whole grain rye crispbread. AB - Sourdough fermentation is considered to have beneficial effects on postprandial satiety and metabolic responses, but studies demonstrating effects at physiological conditions are lacking. The aim of this acute breakfast intervention study was to determine the effect of consumption of sourdough fermented and unfermented rye crispbread on self-rated appetite, postprandial glucose and insulin response in healthy subjects. In all, twenty-four Swedish adults were included in a single-blinded, randomised cross-over trial. Three crispbreads (sourdough-fermented and unfermented whole grain rye and yeast fermented refined wheat as control) were consumed as part of a standardised breakfast. Subjective appetite score, assessed using visual analogue scale, and plasma glucose and insulin concentrations were measured at baseline and postprandially until 360 and 240 min, respectively. Structural changes and viscosity during mastication and gastric digestion were investigated using in vitro methods. Hunger and desire to eat were lower (P<0.05) based on AUC measurements after intake of sourdough-fermented rye crispbread compared with after intake of yeast-fermented refined wheat crispbread. On the basis of AUC (0 230 min), insulin response was lowest after intake of unfermented rye crispbread compared with sourdough-fermented rye and yeast-fermented refined wheat crispbread. Degradation of viscous fibres and faster bolus disintegration for the sourdough-fermented bread may partly explain the less favourable metabolic responses compared with unfermented bread. Our results showed that food processing affects the composition and structural characteristics of rye bread, which has implications for appetite and metabolic responses. PMID- 29185931 TI - Effect of aggregation form on bioavailability of zeaxanthin in humans: a randomised cross-over study. AB - Carotenoid bioavailability from plant and animal food is highly variable depending on numerous factors such as the physical deposition form of carotenoids. As the carotenoid zeaxanthin is believed to play an important role in eye and brain health, we sought to compare the human bioavailability of an H aggregated with that of a J-aggregated deposition form of zeaxanthin encapsulated into identical formulation matrices. A randomised two-way cross-over study with sixteen participants was designed to compare the post-prandial bioavailability of an H-aggregated zeaxanthin and a J-aggregated zeaxanthin dipalmitate formulation, both delivering 10 mg of free zeaxanthin. Carotenoid levels in TAG-rich lipoprotein fractions were analysed over 9.5 h after test meal consumption. Bioavailability from the J-aggregated formulation (AUC=55.9 nmol h/l) was 23 % higher than from the H-aggregated one (AUC=45.5 nmol h/l), although being only marginally significant (P=0.064). Furthermore, the same formulations were subjected to an internationally recognised in vitro digestion protocol to reveal potential strengths and weaknesses of simulated digestions. In agreement with our human study, liberation of zeaxanthin from the J-aggregated formulation into the simulated duodenal fluids was superior to that from the H-aggregated form. However, micellization rate (bioaccessibility) of the J-aggregated zeaxanthin dipalmitate was lower than that of the H-aggregated zeaxanthin, being contradictory to our in vivo results. An insufficient ester cleavage during simulated digestion was suggested to be the root cause for these observations. In brief, combining our in vitro and in vivo observations, the effect of the different aggregation forms on human bioavailability was lower than expected. PMID- 29185932 TI - Effects of partial replacement of maize in the diet with crude glycerin and/or soyabean oil on ruminal fermentation and microbial population in Nellore steers. AB - The objective of this study was to determine whether a combination of crude glycerin (CG) and soyabean oil (SO) could be used to partially replace maize in the diet of Nellore steers while maintaining optimum feed utilisation. Eight castrated Nellore steers fitted with ruminal and duodenal cannulas were used in a double 4*4 Latin square design balanced for residual effects, in a factorial arrangement (A*B), when factor A corresponded to the provision of SO, and factor B to the provision of CG. Steers feed SO and CG showed similar DM intake, DM, organic matter and neutral-detergent fibre digestibility to that of steers fed diets without oil and without glycerine (P>0.05). Both diets with CG additions reduced the acetate:propionate ratio and increased the proportion of iso butyrate, butyrate, iso-valerate and valerate (P<0.05). Steers fed diets containing SO had less total N excretion (P<0.001) and showed greater retained N expressed as % N intake (P=0.022). SO and CG diet generated a greater ruminal abundance of Prevotella, Succinivibrio, Ruminococcus, Syntrophococcus and Succiniclasticum. Archaea abundance (P=0.002) and total ciliate protozoa were less in steers fed diets containing SO (P=0.011). CG associated with lipids could be an energy source, which is a useful strategy for the partial replacement of maize in cattle diets, could result in reduced total N excretion and ruminal methanogens without affecting intake and digestibility. PMID- 29185933 TI - Severe riboflavin deficiency induces alterations in the hepatic proteome of starter Pekin ducks. AB - Suboptimal vitamin B2 status is encountered globally. Riboflavin deficiency depresses growth and results in a fatty liver. The underlying mechanisms remain to be established and an overview of molecular alterations is lacking. We investigated hepatic proteome changes induced by riboflavin deficiency to explain its effects on growth and hepatic lipid metabolism. In all, 360 1-d-old Pekin ducks were divided into three groups of 120 birds each, with twelve replicates and ten birds per replicate. For 21 d, the ducks were fed ad libitum a control diet (CAL), a riboflavin-deficient diet (RD) or were pair-fed with the control diet to the mean daily intake of the RD group (CPF). When comparing RD with CAL and CPF, growth depression, liver enlargement, liver lipid accumulation and enhanced liver SFA (C6 : 0, C12 : 0, C16 : 0, C18 : 0) were observed. In RD, thirty-two proteins were enhanced and thirty-one diminished (>1.5-fold) compared with CAL and CPF. Selected proteins were confirmed by Western blotting. The diminished proteins are mainly involved in fatty acid beta-oxidation and the mitochondrial electron transport chain (ETC), whereas the enhanced proteins are mainly involved in TAG and cholesterol biosynthesis. RD causes liver lipid accumulation and growth depression probably by impairing fatty acid beta oxidation and ETC. These findings contribute to our understanding of the mechanisms of liver lipid metabolic disorders due to RD. PMID- 29185934 TI - The relationships among iron supplement use, Hb concentration and linear growth in young children: Ethiopian Demographic and Health Survey. AB - Growth faltering and anaemia remain unacceptably high among infants and young children in Ethiopia. In this study, we investigated the relationships among Fe supplement use (ISU), Hb concentration and linear growth, hypothesising positive relationships between ISU and Hb, ISU and linear growth and Hb and linear growth. We used a nationally representative data of 2400 children aged 6-24 months from the Ethiopian Demographic and Health Survey (EDHS) 2011, conducted following a stratified, two-stage cluster sampling. We examined the links by Pearson's correlation, bivariate and multivariate linear regression analyses and reported adjusted estimates. We found that ISU was not significantly associated with either Hb (beta=1.09; 95 % CI -2.73, 5.01, P=0.567) or linear growth (beta=0.07; 95 % CI -0.06, 0.21, P=0.217). We found a positive, however, weak, correlation between Hb and linear growth (r 0.09; 95 % CI 0.06, 0.11, P<0.001). Hb predicted linear growth independent of a variety dietary and non-dietary factors (beta=0.08; 95 % CI 0.04, 0.11, P<0.001). Although not the primary focus of the study, our analysis showed that age and breast-feeding duration were independently associated with Hb; age, birth type, size at birth, sex, breast feeding duration, dietary diversity and deworming were independently associated with linear growth, indicating that Hb and linear growth are multifactorial with both nutritional and non-nutritional factors implicated. Further studies, with better design and exposure assessment, are warranted on the relation of ISU with Hb or linear growth. PMID- 29185935 TI - DHA mediates the protective effect of fish consumption on new episodes of depression among women. AB - In a longitudinal cohort study of young Australian adults, we reported that for women higher baseline levels of fish consumption were associated with reduced incidence of new depressive episodes during the 5-year follow-up. Fish are high in both n-3 fatty acids and tyrosine. In this study, we seek to determine whether n-3 fatty acids or tyrosine explain the observed association. During 2004-2006, a FFQ (nine fish items) was used to estimate weekly fish consumption among 546 women aged 26-36 years. A fasting blood sample was taken and high-throughput NMR spectroscopy was used to measure 233 metabolites, including serum n-3 fatty acids and tyrosine. During 2009-2011, new episodes of depression since baseline were identified using the lifetime version of the Composite International Diagnostic Interview. Relative risks were calculated using log-binomial regression and indirect effects estimated using the STATA binary_mediation command. Potential mediators were added to separate models, and mediation was quantified as the proportion of the total effect due to the mediator. The n-3 DHA mediated 25.3 % of the association between fish consumption and depression when fish consumption was analysed as a continuous variable and 16.6 % when dichotomised (reference group: <2 serves/week). Tyrosine did not mediate the association (<0.1 %). Components in fish other than n-3 fatty acids and tyrosine might be beneficial for women's mental health. PMID- 29185936 TI - Consumption of preserved egg, a high-lead-containing food, is strongly associated with depressive symptoms in Chinese adults. AB - Previous studies have demonstrated adverse mental health effects of Pb exposure. The purpose of this study is to investigate the relationship between consumption of preserved egg (PE), a high-Pb-containing food and depressive symptoms among adults in China. A sample of 25 213 adults (mean age 41.4 (sd 11.8) years; males, 53.9 %) in Tianjin, China, was studied in a cross-sectional analysis. Dietary intake including PE was assessed using a valid self-administered FFQ. Depressive symptoms were assessed using the Self-Rating Depression Scale (SDS). The association was estimated by OR using logistic regression models adjusted for multiple confounders. The prevalence of elevated depressive symptoms was 6.6 % (SDS>=50). Compared with the least frequent PE consumption (=4 times/week, respectively (P for trend<0.0001), indicating a clear dose-response relationship. The results suggested that higher consumption of PE was strongly associated with depressive symptoms among adults in China. These findings underscore the need to consider dietary Pb exposure as a risk factor for psychological distress. PMID- 29185938 TI - Thauera propionica sp. nov., isolated from downstream sediment sample of the river Ganges, Kanpur, India. AB - A Gram-stain-negative, non-endospore-producing, short-rod strain, KNDSS-Mac4T, was isolated from a downstream sediment sample of the river Ganges, Kanpur, India and studied by using the polyphasic taxonomic approach. 16S rRNA gene sequence analysis uncovered that the strain had similarity to species of the genus Thauera and formed a distinct phylogenetic cluster with Thauera humireducens KACC16524T. However, KNDSS-Mac4T showed closest phylogenetic affiliation to Thauera aminoaromatica DSM 14742T with 16S rRNA gene sequence similarity of 98.7 % followed by Thauera phenylacetica DSM 14743T (98.6 %), Thauera chlorobenzoica (98.2 %), T. humireducens KACC16524T (98.2 %), Thauera selenatis ATCC 55363T (98.2 %) and Thauera mechernichensis DSM 12266T (98.0 %). The digital DNA-DNA hybridization and average nucleotide identity values between strain KNDSS-Mac4T and the two most closely related taxa, T. aminoaromatica DSM 14742T and T. phenylacetica DSM 14743T, were 26.0, 26.7 and 84.0, 84.3 % respectively. Major lipids present were phosphatidylglycerol, three unknown aminophospholipids, phosphatidylmethylethanolamine, two unidentified lipids and Q-8 as the only ubiquonone. The major cellular fatty acids present were C16 : 1 omega6c/C16 : 1omega7c and C16 : 0. The DNA G+C content of strain KNDSS-Mac4T was 65.9 %. Based on data from phenotypic tests and the genotypic differences of strain KNDSS-Mac4T from its closest phylogenetic relatives, it is evident that this isolate should be regarded as a new species. It is proposed that strain KNDSS-Mac4T should be classified in the genus Thauera as a novel species, Thauerapropionica sp. nov. The type strain is KNDSS-Mac4T (=KCTC 52820T=VTCC-B-910017T). PMID- 29185937 TI - Fastidiosibacter lacustris gen. nov., sp. nov., isolated from a lake water sample, and proposal of Fastidiosibacteraceae fam. nov. within the order Thiotrichales. AB - AFrancisella-like bacterium, designated strain SYSU HZH-2T, was isolated from a water sample collected from Haizhu Lake, Guangzhou, China. The bacterium was fastidious, and required an exogenous source of l-cysteine for its growth on artificial media. Cells were Gram-stain-negative, coccobacilli, non-motile and non-spore-forming. The strain shared highest 16S rRNA gene sequence similarities with Cysteiniphilum litorale SYSU D3-2T (94.6 % identity), Fangia hongkongensis UST040201-002T (93.2 %) and Caedibacter taeniospiralis 51T (91.6 %). This strain possessed ubiquinone-8 as the respiratory quinone; diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine and phosphatidylglycerol as the known polar lipids, and anteiso-C15 : 0 and C18 : 0 as the major fatty acids (>10 % of total fatty acids). The dendrograms based on 16S rRNA gene sequence analysis showed that it formed a separate cluster along with Cysteiniphilum litorale SYSU D3-2T, Caedibactertaeiniospiralis 51T and Fangia hongkongensis UST040201-002T. Based on the 16S rRNA gene sequence identity and differences in other phenotypic characteristics, the strain is considered to represent a novel species of a novel genus, for which the name Fastidiosibacter lacustris gen. nov., sp. nov. is proposed. The type strain of the type species Fastidiosibacter lacustris is SYSU HZH-2T (=NBRC 112274T = CGMCC 1.15950T). Additionally, the new taxon along with the genera Caedibacter, Cysteiniphilum and Fangia (family unassigned) were distinctly separated from the related families Francisellaceae, Piscirickettsiaceae and Thiotrichaeae in the phylogenetic trees. Therefore, we proposed a new family Fastidiosibacteraceae fam. nov. within the order Thiotrichales to accommodate these four genera. PMID- 29185939 TI - Flavobacterium naphthae sp. nov., isolated from oil-contaminated soil. AB - During a study of petroleum hydrocarbon-degrading bacteria, a yellow-coloured, Gram-stain-negative, non-motile and rod-shaped bacterium, designated strain Brt MT, was isolated from oil-contaminated soil of Biratnagar, Morang, Nepal. Strain Brt-MT was able to grow at 15-45 degrees C, pH 5.0-9.0 and 0-1 % (w/v) NaCl concentration. The strain was characterized by multiple taxonomic approaches. Based on 16S rRNA gene sequence analysis, strain Brt-MT belonged to the genus Flavobacterium and shared highest sequence similarity with Flavobacterium cloacae wh15T (95.69 %) and Flavobacterium anatoliense MK3T (94.91 %). The only respiratory quinone was MK-6; the major polar lipid was phosphatidylethanolamine; and the predominant fatty acids were iso-C15 : 0, summed feature 9 (iso-C17 : 1omega9c and/or C16 : 010-methyl), iso-C17 : 0 3-OH and summed feature 3 (C16 : 1omega7c and/or C16 : 1omega6c). The DNA G+C content was 37.2 mol%. The morphological, physiological, chemotaxonomic and phylogenetic analyses clearly distinguished this strain from its closest phylogenetic neighbours. Thus, strain Brt-MT represents a novel species of the genus Flavobacterium, for which the name Flavobacteriumnaphthae sp. nov. is proposed. The type strain is Brt-MT (=KEMB 9005-692T=KACC 19393T=JCM 32171T). PMID- 29185940 TI - Listeria monocytogenes cells under nutrient deprivation showed reduced ability to infect the human intestinal cell line HT-29. AB - PURPOSE: This study aimed to evaluate the effect of two types of stress, cold and nutritional, on the viability and the in vitro virulence of the foodborne pathogenic bacteria Listeria monocytogenes. METHODOLOGY: Ten diverse isolates were kept in phosphate-buffered saline (PBS) at optimal (37 degrees C) or at refrigeration temperature (7 degrees C), for 1 and 7 days. The viability of the cells [log colony-forming units (c.f.u.)/ml] and their in vitro virulence, before and after storage in these conditions, were investigated. In vitro virulence (log PFA) was evaluated using the human intestinal epithelial cell line HT-29 in plaque-forming assays (PFAs).Results/Key findings. In general, when compared with the conditions at 37 degrees C, the exposure at 7 degrees C for 7 days seemed to increase the resistance of the isolates to nutritional stress. Nutritional stress per se acted significantly to decrease the in vitro virulence of the isolates. After 7 days of nutrient deprivation, whether at optimal or at refrigeration temperature, the majority of the isolates assumed a low-virulence phenotype. CONCLUSION: Our results suggest that when L. monocytogenes are in refrigerated post-processing environments that are unable to support their growth they may increase their resistance to nutritional stress and may decrease their virulence. This should be considered when performing risk assessments for refrigerated ready-to-eat (RTE) foods.

PMID- 29185941 TI - Cell-wall recycling and synthesis in Escherichia coli and Pseudomonas aeruginosa their role in the development of resistance. AB - The bacterial cell-wall that forms a protective layer over the inner membrane is called the murein sacculus - a tightly cross-linked peptidoglycan mesh unique to bacteria. Cell-wall synthesis and recycling are critical cellular processes essential for cell growth, elongation and division. Both de novo synthesis and recycling involve an array of enzymes across all cellular compartments, namely the outer membrane, periplasm, inner membrane and cytoplasm. Due to the exclusivity of peptidoglycan in the bacterial cell-wall, these players are the target of choice for many antibacterial agents. Our current understanding of cell wall biochemistry and biogenesis in Gram-negative organisms stems mostly from studies of Escherichia coli. An incomplete knowledge on these processes exists for the opportunistic Gram-negative pathogen, Pseudomonas aeruginosa. In this review, cell-wall synthesis and recycling in the various cellular compartments are compared and contrasted between E. coli and P. aeruginosa. Despite the fact that there is a remarkable similarity of these processes between the two bacterial species, crucial differences alter their resistance to beta-lactams, fluoroquinolones and aminoglycosides. One of the common mediators underlying resistance is the amp system whose mechanism of action is closely associated with the cell-wall recycling pathway. The activation of amp genes results in expression of AmpC beta-lactamase through its cognate regulator AmpR which further regulates multi-drug resistance. In addition, other cell-wall recycling enzymes also contribute to antibiotic resistance. This comprehensive summary of the information should spawn new ideas on how to effectively target cell-wall processes to combat the growing resistance to existing antibiotics.

AB - Alagille syndrome (AGS) is a highly complex, multisystem, autosomal dominant disorder that is caused by a defect in the Notch signaling pathway. This syndrome mainly affects the liver, causing significant cholestasis, which is caused by a paucity of intrahepatic bile ducts. There can be cardiac involvement, including, but not limited to, pulmonary stenosis and tetralogy of Fallot. Patients can also present with butterfly vertebra, ocular issues, and vascular events. Because this syndrome follows an autosomal dominant inheritance, it can have variable expression even in the same family line. For infants in the NICU who have a cardiac defect and persistent hyperbilirubinemia after two weeks of age, genetic testing for AGS should be considered. Early detection and diagnosis can lead to improved outcomes. In this discussion of AGS, the clinical features as well as management are discussed.

AB - PURPOSE: To identify the nursing care procedures (NCPs) performed in a NICU that disrupt the thermal environment by opening the incubator of moderately preterm neonates (mPNs) (32-34 wk gestational age) and the relationship between the frequency of these disruptions and change in weight (Deltawt). DESIGN: Survey and descriptive correlational methodology. SAMPLE: Systematically identified, published references to NCPs that opening the incubator developed an itemized list of NCPs that was used to query the electronic health records (EHRs) of 164 mPNs in the first ten days of life (DOL). MAIN OUTCOME VARIABLE: The Deltawt between birth and ten DOL. RESULTS: Of 51 NCPs identified, 26 were represented in the EHR. A mean of 614 (range 402-1,080; SD = 137) EHR-documented NCPs that opening the incubator were recorded. The frequency of NCPs was negatively correlated with the Deltawt of mPNs at ten DOL, rs (164) = -.162, p = .038.

AB - PURPOSE: To develop and content validate the Neonatal Eating Assessment Tool (NeoEAT), a parent-report measure of infant feeding. DESIGN: The NeoEAT was developed in three phases. Phase 1: Items were generated from a literature review, available assessment tools, and parents' descriptions of problematic feeding in infants.Phase 2: Professionals rated items for relevance and clarity. Content validity indices were calculated. Phase 3: Parent understanding was explored through cognitive interviews. SAMPLE: Phase 1: Descriptions of infant feeding were obtained from 12 parents of children with diagnosed feeding problems and 29 parents of infants younger than seven months. Phase 2: Nine professionals rated items. Phase 3: Sixteen parents of infants younger than seven months completed the cognitive interview. MAIN OUTCOME VARIABLE: Content validity of the NeoEAT. RESULTS: Three versions were developed: NeoEAT Breastfeeding (72 items), NeoEAT Bottle Feeding (74 items), and NeoEAT Breastfeeding and Bottle Feeding (89 items).

AB - Pneumopericardium occurs when air accumulates in the pericardial sac surrounding the heart and is one of the rarest forms of air leaks in neonates. Because of various advances in neonatal care, including gentler modes of ventilation, surfactant replacement, and antenatal steroids, the incidence of pneumopericardium has decreased. Despite the decrease in incidence of pneumopericardium, most cases arise in premature infants with a history of respiratory distress and mechanical ventilation. Evidence has shown that the incidence is inversely related to birth weight and that pneumopericardium has high mortality and morbidity rates.

AB - The incompatibility (Inc) P-7 group plasmid pCAR1 can be efficiently transferred among bacteria in artificial microcosms in the presence of divalent cations Ca2+ and Mg2+. One-on-one mating assays between Pseudomonas strains with different plasmids showed that the promotion of conjugation efficiency by divalent cations was exhibited in other plasmids, including pB10 and NAH7; however, this effect was larger in IncP-7 plasmids. The impact on pCAR1 conjugation differed according to donor-recipient pairs, and conjugation efficiency promotion was clearly detected between the donors P. resinovorans CA10dm4 and P. fluorescens Pf0-1 and the recipients P. putida KT2440 and CA10dm4. Transcriptome analyses showed that pCAR1 gene expression did not respond to cation changes, including the tra/trh genes involved in its transfer. However, the transcription of oprH genes, encoding putative outer-membrane proteins in both the donor and the recipient, were commonly upregulated under cation-limited conditions. The conjugation frequency of pCAR1 in the KT2440 oprH mutant was found not to respond to cations. This effect was partially recovered by complementation with the oprH gene, suggesting that OprH is involved in the increase of pCAR1 conjugation efficiency by divalent cations. PMID- 29185955 TI - Paraburkholderia azotifigens sp. nov., a nitrogen-fixing bacterium isolated from paddy soil. AB - A Gram-stain-negative, aerobic, non-motile and rod-shaped bacterial strain, designated NF2-5-3T, was isolated from a paddy soil in Anseong city, Republic of Korea. This bacterium was characterized to determine its taxonomic position using a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain NF2-5-3T had a close relationship with, and was related most closely to, members of the genus Paraburkholderia, namely Paraburkholderia caribensis MWAP64T (98.8 % similarity), P. sabiae Br3407T (98.8 %), P. hospita LMG 20598T (98.5 %), P. terrae NBRC 100964T (98.3 %) and P. phymatum STM815T (98.1 %). Growth of strain NF2-5-3T occurred at 15-37 degrees C, at pH 6.0-8.0 and at NaCl concentrations of 0-2 % (w/v). The major respiratory quinone was ubiquinone 8 (Q-8) and the major fatty acids were C16 : 0, summed feature 8 (comprising C18 : 1omega7c and/or C18 : 1omega6c), C17 : 0 cyclo and C16 : 0 3-OH. The polar lipid profile consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, an unidentified phospholipid, unidentified aminophospholipids, unidentified aminolipids and unidentified polar lipids. The G+C content of the genomic DNA was 64.2 mol%. DNA-DNA relatedness values between strain NF2-5-3T and its closest phylogenetic neighbours were much lower than 70 %. Strain NF2-5-3T could be differentiated phylogenetically and phenotypically from recognized species of the genus Paraburkholderia. The isolate therefore represents a novel species, for which the name Paraburkholderia azotifigens sp. nov. is proposed, with NF2-5-3T (=KACC 18968T=LMG 29961T) as the type strain. PMID- 29185956 TI - Diagnostic value of BiP or anti-BiP antibodies for rheumatoid arthritis: a meta analysis. AB - OBJECTIVES: To evaluate the diagnostic value of BiP or anti-BiP antibodies in patients with rheumatoid arthritis. METHODS: Relevant studies published on PubMed and CNKI from January 1995 to July 2016 were retrieved. Two reviewers independently evaluated studies and QUADAS tool was used to assess the quality of the included studies. A random-effects model was used to combine sensitivity, specificity, positive and negative likelihood ratios and diagnostic odds ratio. Stratified analysis was performed for exploring heterogeneity and funnel plot was examined for the possibility of publication bias. RESULTS: Nine studies met our inclusion criteria. The pooled sensitivity, specificity, LR+, LR-, DOR were 0.67 (95%CI, 0.64-0.70), 0.92 (95%CI, 0.90-0.93), 7.65(95%CI, 4.08-14.36), 0.36(95%CI, 0.33-0.39), 23.73(95%CI, 13.01-43.28), respectively. CONCLUSIONS: This meta analysis shows that BiP or anti-BiP antibodies have a moderate accuracy for the diagnosis of rheumatoid arthritis with a moderate sensitivity and high specificity. It can be an efficient supplement to the existing diagnostic method. PMID- 29185957 TI - The utility of the ACR/EULAR 2017 provisional classification criteria for granulomatosis with polyangiitis in Korean patients with antineutrophil cytoplasmic antibody-associated vasculitis. AB - OBJECTIVES: We applied the ACR/EULAR 2017 provisional classification criteria for granulomatosis with polyangiitis (GPA) to 150 Korean patients with previously diagnosed antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and investigated how many patients with AAV were reclassified as GPA. METHODS: We included patients with 30 GPA, 30 eosinophilic GPA (EGPA) and 90 microscopic polyangiitis (MPA) patients. Patients can be classified as GPA, when the sum of scores is more than 5. RESULTS: At diagnosis the mean age of 150 patients with AAV was 60.1 years old, and 101 patients (67.3%) were women. Overall, 33 of 150 patients with AAV (22.0%) were classified as GPA according to the 2017 provisional criteria for GPA. The 2017 provisional criteria for GPA dropped to 10.0% of previously diagnosed GPA patients and the major factor to drop 3 GPA patients was the deletion of 2 items of the 1990 criteria, urinary sediment and infiltrates on chest radiograph. Meanwhile, one of 30 patients with EGPA (3.3%) and 5 of 90 patients with MPA (5.6%) were newly classified as GPA based on the 2017 provisional criteria for GPA. We could also find that items of the 2017 provisional criteria to contribute to reclassifying EGPA and MPA patients as GPA were PR3-ANCA, mass-like lung lesion and nasal congestion in Korean patients with AAV. CONCLUSIONS: The use of the 2017 provisional criteria for GPA excluded 10.0% of previously classified GPA patients and newly classified 3.3% of EGPA patients and 5.6% of MPA patients as GPA in Korean patients with AAV. PMID- 29185958 TI - Are rheumatologists adhering to the concepts window of opportunity and treat-to target? Earlier and more intense disease-modifying anti-rheumatic drug treatment over time in patients with early arthritis in the PEARL study. AB - OBJECTIVES: To analyse changes over time in the treatment with disease modifying anti-rheumatic drugs and biological therapies prescribed to patients from an early arthritis register and whether these changes had an impact on their outcome. METHODS: This was a longitudinal retrospective 2-year study based on data collected in the PEARL study. The population was clustered in three groups depending on year of symptoms onset (2000-2004, 2005-2009, 2010-2014). Intensity of disease-modifying anti-rheumatic drug treatment was calculated and the percentage of patients receiving biological therapy during the first 2-year follow-up was collected. Disease activity and remission at the end of follow-up, as well as radiological progression were the outcomes analysed. Multivariable analyses were fitted to determine which variables including the three period times were associated with the outcomes. RESULTS: A significant increase in treatment intensity was observed in patients with undifferentiated arthritis, getting closer to that prescribed to patients fulfilling the 1987 RA criteria at the last period studied (2010-2014). This finding was associated with a significantly higher percentage of patients in remission and lower progression of the erosion component of the Sharp van der Heijde score. CONCLUSIONS: During the last 15 years, the treatment of patients with early arthritis in our hospital has been progressively increased and it has been associated with significantly better outcomes. PMID- 29185959 TI - Recommendations for the use of biologics and other novel drugs in the treatment of psoriatic arthritis: 2017 update from the Italian Society of Rheumatology. AB - OBJECTIVES: To update the 2011 Italian Society of Rheumatology (SIR) recommendations for the use of biologics and other novel agents in the treatment of psoriatic arthritis (PsA). METHODS: To create this new set of recommendations, the SIR "Spondyloartritis and Psoriatic Arthritis study group - A. Spadaro" went through the following steps: literature search, identification of the items of interests for each of the four previously identified clinical domains of PsA and the different treatment phases, achievement of the consensus on all topics, and generation of the recommendations. RESULTS: An update on the available evidence on all of the biologics and new small molecules tested in PsA is reported, comprising the data for each of the individual articular manifestation. Indications for therapy inclusion criteria, choice of the drug, disease assessment, response definition, therapy failure management, and disease remission management for PsA peripheral joint arthritis, enthesitis, dactylitis, and spondylitis are provided. Suggestions for the treatment of patients with PsA and concomitant extra-articular manifestations are also given. CONCLUSIONS: These evidence-based recommendations may be used for guidance in the complex and fast evolving field of the treatment of PsA.

PMID- 29185961 TI - Recommendations for the management of pulmonary fungal infections in patients with rheumatoid arthritis. AB - Often life-threatening pulmonary fungal infections (PFIs) can occur in patients with rheumatoid arthritis (RA) receiving disease-modifying anti-rheumatic drugs (DMARDs). Most of the data concerning PFIs in RA patients come from case reports and retrospective case series. Of the ve most widely described PFIs, Pneumocystis jirovecii pneumonia (PJP) has rarely been seen outside Japan, pulmonary cryptococcosis has been diagnosed in only a small number of patients worldwide, pulmonary coccidioidomycosis has almost only been observed in endemic areas, the limited number of cases of pulmonary histoplasmosis have mainly occurred in the USA, and the rare cases of invasive pulmonary aspergillosis have only been encountered in leukopenic patients. Many aspects of the prophylaxis, diagnosis and treatment of PFIs in RA patients remain to be defined, as does the role of each DMARD in increasing the risk of infection, and the possibility of resuming biological and non-biological DMARD treatment after the infection has been cured. The recommendations for the management of PFIs described in this paper are the product of a consensus procedure promoted by the Italian group for the Study and Management of Infections in Patients with Rheumatic Diseases (the ISMIR group). PMID- 29185962 TI - Renal outcome of kidney-transplantation in Korean recipients with ANCA-associated vasculitis. AB - OBJECTIVES: We investigated renal outcome of kidney-transplantation in Korean recipients with biopsy-proven renal involvement of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) in a single centre. METHODS: We reviewed the medical records of 144 Korean patients and included 3 female patients with microscopic polyangiitis (MPA) and one male patient with eosinophilic granulomatosis with polyangiitis (EGPA) in this study. We obtained clinical and laboratory data related to kidney-transplantation, analysed renal outcome of kidney-transplantation in 4 recipients with AAV and compared it with those of previous studies. RESULTS: The mean age at diagnosis was 37.8 years and that at kidney-transplantation was 40.8 years. Time-gap from AAV to ESRD ranged from 1 to 48 months and that from AAV to kidney-transplantation ranged from 2 to 95 months. All kidney-recipients with had been followed-up for two years or greater. At diagnosis, MPO-ANCA was detected in only MPA patients, while, at transplantation, MPA-ANCA was detected in 2 MPA patients and an EGPA patient. All patients have received tacrolimus and mycophenolate mofetil based on glucocorticoid after kidney-transplantation. Among 4 kidney-recipients with AAV, one MPA patient underwent renal re-biopsies three times due to renal function deterioration during the follow-up. Renal histology revealed T cell-mediated and antibody-mediated rejection rather than relapse of MPA. Neither relapse nor graft failure was observed in our study. CONCLUSIONS: Renal outcome of kidney transplantation in recipients with AAV was good and kidney-transplantation is deserved to be recommend as a safe and effective therapeutic modality to AAV patients with ESRD.

PMID- 29185963 TI - The therapeutic nuclear magnetic resonance changes the balance in intracellular calcium and reduces the interleukin-1beta induced increase of NF-kappaB activity in chondrocytes. AB - OBJECTIVES: Osteoarthritis as the main chronic joint disease is characterised by the destruction of articular cartilage. Developing new, more effective and in particular non-invasive methods to achieve pain reduction of OA patients are of exceptional interest. Clinical observations demonstrated positive effects of therapeutically applied low nuclear magnetic resonance (NMRT) for the treatment of painful disorders of the musculoskeletal system. In this study the cellular mechanism of action of NMRT was examined on chondrocytes. METHODS: Cal-78 human chondrosarcoma cells were kept under inflammatory conditions by application of IL 1beta. NMRT treated cells were tested for changes in histamine induced Ca2+ release by fura-2 calcium imaging. The effects of IL-1beta and of NMRT treatment were further tested by determining intracellular ATP concentrations and the activity of MAP-kinases and NF-kappaB. RESULTS: NMRT influenced the intracellular calcium signalling by elevating the basal [Ca2+]i. The peak calcium concentration evoked by 10 MUM histamine was increased by IL-1beta and this increase was reversed under NMRT treatment. Screening of different kinase-activities revealed an apparent increase in activity of MAPK/ERK and MAPK/JNK in NMRT stimulated cells, p38 was downregulated. The IL-1beta-induced decline in intracellular ATP and the elevated NF-kappaB activity was reversed under NMRT stimulation. CONCLUSIONS: Under inflammatory conditions, NMRT influenced cellular functions by modulating cellular calcium influx and/or calcium release. Further, NMRT induced changes in MAPK activities such as down-regulation of NF-kappaB and increasing intracellular ATP might help to stabilise chondrocytes and delay cartilage damage due to OA. PMID- 29185965 TI - Ultrasound changes in synovial abnormalities induced by treatment in juvenile idiopathic arthritis. AB - OBJECTIVES: To investigate the capacity of ultrasound (US) to detect improvement of synovial abnormalities induced by treatment in juvenile idiopathic arthritis (JIA). METHODS: Eighty-three joints (33 knees, 22 tibiotalar, 10 wrists, 9 elbows, 9 subtalar joints) of 33 patients with new-onset JIA were assessed by US at study entry and 6 months after a therapeutic intervention. Each joint was scored for grey-scale (GS) and power Doppler (PD) abnormalities according to a 4 point semiquantitative scale. Pre- and post-treatment US scores were compared and the sensitivity to change of GSUS and PDUS was estimated. Clinical response was assessed using the ACR paediatric (ACRp) response criteria. RESULTS: Seventeen patients (51.5%) underwent intra-articular corticosteroid injection (IACI) only, 15 (45.5%) were given IACI and systemic medications, and 1 (3.0%) was started with systemic therapy alone. Both GSUS and PDUS scores improved significantly (p<0.0001) from baseline to follow-up. US revealed strong sensitivity to change with standardised response mean for GSUS and PDUS of 2.44 and 1.23, respectively. At the follow-up visit, 13/20 (65.0%) joints with residual US abnormalities were judged in remission on clinical grounds. Six/21 (28.6%) patients who were ACRp90 responders did not display complete resolution of synovial abnormalities on US. CONCLUSIONS: US is a sensitive tool to assess therapeutic response in patients with JIA. Subclinical disease on US is common in joints with clinically-defined remission. An ACRp90 response may not be coupled with complete resolution of synovial abnormalities on US. Further studies are needed to establish the impact of US on therapeutic decision-making in JIA.

PMID- 29185966 TI - The prevalence and clinical effect of immunogenicity of TNF-alpha blockers in patients with axial spondyloarthritis. AB - OBJECTIVES: To evaluate the prevalence of immunogenicity of TNF-alpha blockers in axial spondyloarthritis (SpA) patients and to assess the effect of immunogenicity on drug levels and clinical response. METHPDS: Patients with axial SpA treated with either infliximab (INF), adalimumab (ADA) or etanercept (ETN) were recruited to our observational cross-sectional study. Demographic and clinical data were collected and disease activity scores were assessed. Drug trough levels and anti drug antibodies were measured in serum samples and collected before the next administration. RESULTS: Thirty-nine patients with axial SpA with a mean age of 46.3+/-12.7 (10 women) were recruited to the study (14 receiving INF, 16 ADA and 9 ETN). Patients' mean therapy duration was 50.6 months (+/-46.4) and 6 (15%) of them were using MTX concomitantly with the TNF-alpha blockers. Anti-drug antibodies were found in 6 (15%) patients (4 with INF and 2 with ADA), all of which had undetectable drug level. No anti-drug antibodies were detected in patients treated with ETN. Immunogenicity was associated with higher BASDAI (Bath Ankylosing Spondylitis Disease Index), ASDAS-CRP (Ankylosing Spondylitis Disease Activity Score) and ASDAS-ESR. CONCLUSIONS: Axial SpA patients failure to respond to TNF-alpha blockers may be at least partially related to immunogenicity. Measurement of anti-drug antibodies and drug levels in these patients may assist in determining further treatment strategies. PMID- 29185968 TI - The performance of anti-cyclic citrullinated peptide assays in diagnosing rheumatoid arthritis: a systematic review and meta-analysis. AB - OBJECTIVES: We assessed the ability of anti-cyclic citrullinated peptide (CCP) tests to diagnose rheumatoid arthritis (RA), comparing the effect of manufacturer assay type, study design (single- and two-gated) and duration of disease (early vs. established). METHODS: We searched seven databases for relevant diagnostic studies containing data on CCP tests in known or suspected RA patients. We used a bivariate model to produce summary estimates for test sensitivity, specificity, and positive and negative likelihood ratios. Summary Receiver Operating Characteristic (sROC) curves were derived to compare early versus established RA. RESULTS: 83 studies were identified and included. For individual manufacturer tests there was considerable variation in both pooled sensitivity (range 67-83%) and specificity (range 90-96%) estimates. This heterogeneity was also observed when grouping studies into two-gated and single-gated designs. Study design and disease duration impacted on sensitivity, with single-gated study designs and early RA patients resulting in lower estimates than two-gated and established disease, respectively. CONCLUSIONS: This review highlights the large number of CCP tests that are now commercially available and the considerable variation in their diagnostic performance. This variation, although partly influenced in this analysis by the study design (single-gated vs. two-gated), seems to have different levels of impact depending on the manufacturers. The Thermo Fisher Scientific EliA and Inova Diagnostics Quanta Lite (CCP2) tests showed the least between-study variation in sensitivity and specificity suggesting they have the most consistent diagnostic performance overall.

PMID- 29185969 TI - Arterial wave reflection and subclinical atherosclerosis in rheumatoid arthritis. AB - OBJECTIVES: Atherosclerotic cardiovascular disease risk is increased in rheumatoid arthritis (RA). Wave reflection occurs at arterial branching points, which are particularly prone to atherosclerosis. We explored the relationship of wave reflection with atherosclerosis in RA. METHODS: One hundred and sixty three RA patients (110 white, 31 Asian, 17 black and 5 of mixed ancestry) without cardiovascular disease participated. Arterial stiffness, wave reflection, pressure pulsatility, plaque in the extracranial carotid artery tree and the mean of the left and right common carotid arteries intima-thickness were determined. Associations were identified in multivariable regression models. RESULTS: One SD increase in reflected wave pressure (OR (95% CI) = 2.54 (1.41-4.44), p=0.001), reflection magnitude (OR (95% CI) = 1.84 (1.17-2.89), p=0.008), central pulse pressure (OR (95% CI) = 1.89 (1.12-3.22), p=0.02) and peripheral pulse pressure (OR (95% CI) = 2.09 (1.23-3.57), p=0.007) were associated with plaque. The association of wave reflection with plaque was independent of arterial stiffness and pressure pulsatility, and was present in both hypertensive and normotensive RA patients. In receiver operator characteristic curve analysis, the optimal cutoff value for reflected wave pressure in predicting plaque presence was 25 mmHg with a sensitivity, specificity, positive predictive value and negative predictive value of 45.2%, 89.3%, 78.6% and 66.2%, respectively; a reflected wave pressure of >25 mmHg was associated with plaque in univariate and adjusted analysis (p<0.0001 for both). Arterial function was not independently related to carotid intima-media thickness. CONCLUSIONS: Consideration and therapeutic targeting of wave reflection may improve cardiovascular disease prevention in RA. PMID- 29185971 TI - Biosimilars Shake Off Doubters, Go on a Roll.

PMID- 29185982 TI - Adrenergic regulation during acute hepatic infection with Entamoeba histolytica in the hamster: involvement of oxidative stress, Nrf2 and NF-KappaB. AB - Oxidative stress and transcriptional pathways of nuclear factor erythroid 2 related factor 2 (Nrf2) and nuclear factor kappa-B (NF-kappaB) are critically involved in the etiopathology of amebic liver abscess (ALA). In this work, we studied the relationship between the adrenergic nervous system and ALA in the hamster. ALA was visible at 12 h of infection. While 6-hydroxidopamine (6-OHDA) decreased infection, propranolol (beta-adrenergic blocker) treatment was associated with less extensive liver damage, and phentolamine treatment (alpha adrenergic blocker) significantly reduced ALA compared to 6-OHDA and propranolol. Serum enzymatic activities of alanine aminotransferase (ALT) and gamma-glutamyl transpeptidase (gamma-GTP) were increased at 12 h post-infection. Chemical denervation and alpha and beta-adrenergic blockers decreased ALT to normal levels, while 6-OHDA and propranolol showed a trend to decrease gamma-GTP but phentolamine significantly reduced gamma-GTP. Amebic infection increased oxidized glutathione (GSSG) and decreased both reduced glutathione (GSH) and the GSH/GSSG ratio. Propranolol and 6-OHDA showed a tendency to decrease GSSG. However, GSH, GSSG and GSH/GSSG returned to normal levels with phentolamine. Furthermore, amebic infection increased pNF-kappaB and interleukin-1beta (IL-1beta), and showed a tendency to decrease hemoxigenase-1 (HO-1), but not Nrf2. Chemical denervation showed a trend to decrease pNF-kappaB and IL-1beta, and neither Nrf2 nor HO-1 increased significantly. In addition, NF-kappaB and IL-1beta were attenuated by propranolol and phentolamine treatments, although phentolamine showed significant overexpression of Nrf2 and HO-1. This suggests that the adrenergic system may be involved in oxidative stress and in modulation of the Nrf2 and NF-kappaB pathways during ALA development. PMID- 29185985 TI - Parallel Block Sequential Closed-Form Matting With Fan-Shaped Partitions. AB - Applying alpha matting to large images is a challenging task because of its computational complexity. This paper provides a divide and conquer strategy for performing closed-form matting. The matting problem, defined for an entire image, is broken down into systems of linear equations defined for very small blocks of the image. The sizes of the small systems are small enough for us to find solutions efficiently using a direct sparse linear equation system solver. The small systems are solved following a sequential order such that the alpha matte grows from a user scribble. With the block sequential application, matting is performed on fan-shaped partitions in parallel on multiple processing cores. Experiments on large test images as well as on standard benchmark test images show that the proposed parallel block sequential matting provides high quality alpha mattes with good scalability. PMID- 29185983 TI - NuMA recruits dynein activity to microtubule minus-ends at mitosis. AB - To build the spindle at mitosis, motors exert spatially regulated forces on microtubules. We know that dynein pulls on mammalian spindle microtubule minus ends, and this localized activity at ends is predicted to allow dynein to cluster microtubules into poles. How dynein becomes enriched at minus-ends is not known. Here, we use quantitative imaging and laser ablation to show that NuMA targets dynactin to minus-ends, localizing dynein activity there. NuMA is recruited to new minus-ends independently of dynein and more quickly than dynactin; both NuMA and dynactin display specific, steady-state binding at minus-ends. NuMA localization to minus-ends involves a C-terminal region outside NuMA's canonical microtubule-binding domain and is independent of minus-end binders gamma-TuRC, CAMSAP1, and KANSL1/3. Both NuMA's minus-end-binding and dynein-dynactin-binding modules are required to rescue focused, bipolar spindle organization. Thus, NuMA may serve as a mitosis-specific minus-end cargo adaptor, targeting dynein activity to minus-ends to cluster spindle microtubules into poles. PMID- 29185986 TI - Novel Integration of Frame Rate Up Conversion and HEVC Coding Based on Rate Distortion Optimization. AB - Frame rate up conversion (FRUC) can improve the visual quality by interpolating new intermediate frames. However, high frame rate videos by FRUC are confronted with more bitrate consumption or annoying artifacts of interpolated frames. In this paper, a novel integration framework of FRUC and high efficiency video coding (HEVC) is proposed based on rate-distortion optimization, and the interpolated frames can be reconstructed at encoder side with low bitrate cost and high visual quality. First, joint motion estimation (JME) algorithm is proposed to obtain robust motion vectors, which are shared between FRUC and video coding. What's more, JME is embedded into the coding loop and employs the original motion search strategy in HEVC coding. Then, the frame interpolation is formulated as a rate-distortion optimization problem, where both the coding bitrate consumption and visual quality are taken into account. Due to the absence of original frames, the distortion model for interpolated frames is established according to the motion vector reliability and coding quantization error. Experimental results demonstrate that the proposed framework can achieve 21% ~ 42% reduction in BDBR, when compared with the traditional methods of FRUC cascaded with coding. PMID- 29185984 TI - Conserved RNA-binding specificity of polycomb repressive complex 2 is achieved by dispersed amino acid patches in EZH2. AB - Polycomb repressive complex 2 (PRC2) is a key chromatin modifier responsible for methylation of lysine 27 in histone H3. PRC2 has been shown to interact with thousands of RNA species in vivo, but understanding the physiological function of RNA binding has been hampered by the lack of separation-of-function mutants. Here, we use comprehensive mutagenesis and hydrogen deuterium exchange mass spectrometry (HDX-MS) to identify critical residues for RNA interaction in PRC2 core complexes from Homo sapiens and Chaetomium thermophilum, for which crystal structures are known. Preferential binding of G-quadruplex RNA is conserved, surprisingly using different protein elements. Key RNA-binding residues are spread out along the surface of EZH2, with other subunits including EED also contributing, and missense mutations of some of these residues have been found in cancer patients. The unusual nature of this protein-RNA interaction provides a paradigm for other epigenetic modifiers that bind RNA without canonical RNA binding motifs.

Visualizations of learned features at various layers and their deconvolutions are also presented for understanding the learning process. PMID- 29185988 TI - Saliency Detection Based on Multiscale Extrema of Local Perceptual Color Differences. AB - Visual saliency detection is a useful technique for predicting, which regions humans will tend to gaze upon in any given image. Over the last several decades, numerous algorithms for automatic saliency detection have been proposed and shown to work well on both synthetic and natural images. However, two key challenges remain largely unaddressed: 1) How to improve the relatively low predictive performance for images that contain large objects and 2) how to perform saliency detection on a wider variety of images from various categories without training. In this paper, we propose a new saliency detection algorithm that addresses these challenges. Our model first detects potentially salient regions based on multiscale extrema of local perceived color differences measured in the CIELAB color space. These extrema are highly effective for estimating the locations, sizes, and saliency levels of candidate regions. The local saliency candidates are further refined via two global extrema-based features, and then a Gaussian mixture is used to generate the final saliency map. Experimental validation on the extensive CAT2000 data set demonstrates that our proposed method either outperforms or is highly competitive with prior approaches, and can perform well across different categories and object sizes, while remaining training-free.

It has not been well investigated on how to measure depth perception quality independently under different distortion categories and degrees, especially exploit the depth perception to assist the overall quality assessment of 3D videos. In this paper, we propose a new depth perception quality metric (DPQM) and verify that it outperforms existing metrics on our published 3D video extension of High Efficiency Video Coding (3D-HEVC) video database. Furthermore, we validate its effectiveness by applying the crucial part of the DPQM to a novel blind stereoscopic video quality evaluator (BSVQE) for overall 3D video quality assessment. In the DPQM, we introduce the feature of auto-regressive prediction based disparity entropy (ARDE) measurement and the feature of energy weighted video content measurement, which are inspired by the free-energy principle and the binocular vision mechanism. In the BSVQE, the binocular summation and difference operations are integrated together with the fusion natural scene statistic measurement and the ARDE measurement to reveal the key influence from texture and disparity. Experimental results on three stereoscopic video databases demonstrate that our method outperforms state-of-the-art SVQA algorithms for both symmetrically and asymmetrically distorted stereoscopic video pairs of various distortion types.

AB - In brain computer interface (BCI) applications, the use of steady-state visually evoked potentials (SSVEPs) is common. Therefore, a visual stimulation with a constant repetition frequency is necessary. However, using a computer monitor, the set of frequencies that can be used is restricted by the refresh rate of the screen. Frequencies that are not an integer divisor of the refresh rate cannot be displayed correctly. Furthermore, the programming language the stimulation software is written in and the operating system influence the actually generated and presented frequencies. The aim of this paper is to identify the main challenges in generating SSVEP stimulation using a computer screen with and without using DirectX in Windows-based PC systems and to provide solutions for these issues.

AB - Favipiravir is a novel antiviral drug approved for influenza treatment in Japan. Little is known about favipiravir pharmacokinetics in critically ill patients. Here, we report a patient with influenza treated with favipiravir and undergoing continuous venovenous haemofiltration (CVVH) on the Intensive Care Unit of a tertiary hospital in the Netherlands. Pharmacokinetic analyses showed increased clearance and decreased plasma levels compared to healthy volunteers. CVVH has no clinically relevant contribution to total clearance. Despite susceptibility to favipiravir, the influenza virus was not cleared. A multi-disciplinary approach is needed to ensure optimal favipiravir treatment in critically ill patients. PMID- 29185992 TI - Fixed forced detection for fast SPECT Monte-Carlo simulation. AB - Monte-Carlo simulations of SPECT images are notoriously slow to converge due to the large ratio between the number of photons emitted and detected in the collimator. This work proposes a method to accelerate the simulations based on fixed forced detection (FFD) combined with an analytical response of the detector. FFD is based on a Monte-Carlo simulation but forces the detection of a photon in each detector pixel weighted by the probability of emission (or scattering) and transmission to this pixel. The method was evaluated with numerical phantoms and on patient images. We obtained differences with analog Monte Carlo lower than the statistical uncertainty. The overall computing time gain can reach up to five orders of magnitude. Source code and examples are available in the Gate V8.0 release. PMID- 29185993 TI - Detection of protease activity by fluorescent protein FRET sensors: from computer simulation to live cells. AB - Forster resonance energy transfer (FRET) sensors are widely used for the detection of protease activity in vitro and in vivo. Usually they consist of a FRET pair connected with a polypeptide linker containing a specific cleavage site for the relevant protease. Use of the fluorescent proteins as components of the FRET pair allows genetic encoding of such sensors and solves the problem of their delivery into live cells and animals. There are several ways to improve the properties of such sensors, mainly to increase FRET efficiency and therefore the dynamic range. One of the ways to achieve this is to use a non-fluorescent chromoprotein as an acceptor. Molecular dynamic simulations may assist in the construction of linker structures connecting donor and acceptor molecules. Estimation of the orientation factor kappa 2 can be obtained by methods based on quantum theory and combined quantum mechanics/molecular mechanics approaches. The linker can be structured by hydrophobic interactions, bringing it into a closed conformation that shortens the distance between donor and acceptor and, consequently, increases FRET efficiency. We analyzed the effects of different linker structures on the detection of caspase-3 activity using a non-fluorescent acceptor. Also we have constructed the Tb3+- TagRFP sensor in which a complex of the terbium ion and terbium-binding peptide is used as a donor. This allowed us to use the unique property of lanthanide ions-fluorescence lifetime up to milliseconds-to perform measurements with time delay and exclude the nanosecond order fluorescence. Using our systems as a starting point, by changing the recognition site in the linker it is possible to perform imaging of different protease activity in vitro or in vivo.

AB - OBJECTIVE: This work aims to investigate the impact of gestational age and fetal gender on fetal heart rate (FHR) tracings. APPROACH: Different linear and nonlinear parameters indicating correlation or complexity were used to study the influence of fetal age and gender on FHR tracings. The signals were recorded from 99 normal pregnant women in a singleton pregnancy at gestational ages from 28 to 40 weeks, before the onset of labor. There were 56 female fetuses and 43 male. MAIN RESULTS: Analysis of FHR shows that the means as well as measures of irregularity of FHR, such as approximate entropy and algorithmic complexity, decrease as gestation progresses. There were also indications that mutual information and multiscale entropy were lower in male fetuses in early pregnancy. SIGNIFICANCE: Fetal age and gender seem to influence FHR tracings. Taking this into consideration would improve the interpretation of FHR monitoring. PMID- 29185995 TI - Noise creates polarization artefacts. AB - The accuracy of calculations of both the degree and angle of polarization depend strongly on the noise in the measurements used. The noise in the measurements recorded by both camera based systems and spectrometers can lead to significant artefacts and incorrect conclusions about high degrees of polarization when in fact none exist. Three approaches are taken in this work: firstly, the absolute error introduced as a function of the signal to noise ratio for polarization measurements is quantified in detail. An important finding here is the reason for why several studies incorrectly suggest that black (low reflectivity) objects are highly polarized. The high degree of polarization is only an artefact of the noise in the calculation. Secondly, several simple steps to avoid such errors are suggested. Thirdly, if these points can not be followed, two methods are presented for mitigating the effects of noise: a maximum likelihood estimation method and a new denoising algorithm to best calculate the degree of polarization of natural polarization information. PMID- 29185996 TI - Electrical conductivity of In2O3 and Ga2O3 after low temperature ion irradiation; implications for instrinsic defect formation and charge neutrality level. AB - The evolution of sheet resistance of n-type In2O3 and Ga2O3 exposed to bombardment with MeV 12C and 28Si ions at 35 K is studied in situ. While the sheet resistance of Ga2O3 increased by more than 8 orders of magnitude as a result of ion irradiation, In2O3 showed a more complex defect evolution and became more conductive when irradiated at the highest doses. Heating up to room temperature reduced the sheet resistivity somewhat, but Ga2O3 remained highly resistive, while In2O3 showed a lower resistance than as deposited samples. Thermal admittance spectroscopy and deep level transient spectroscopy did not reveal new defect levels for irradiation up to 2 1012 cm2. A model where larger defect complexes preferentially produce donor like defects in In2O3 is proposed, and may reveal a microscopic view of a charge neutrality level within the conduction band, as previously proposed. PMID- 29185997 TI - Site occupancy, composition and magnetic structure dependencies of martensitic transformation in Mn2Ni1 + x Sn1-x. AB - A delicate balance between various factors such as site occupancy, composition and magnetic ordering seems to affect the stability of the martensitic phase in [Formula: see text] [Formula: see text] [Formula: see text]. Using first principles DFT calculations, we explore the impacts of each one of these factors on the martensitic stability of this system. Our results on total energies, magnetic moments and electronic structures upon changes in the composition, the magnetic configurations and the site occupancies show that the occupancies at the 4d sites in the inverse Heusler crystal structure play the most crucial role. The presence of Mn at the 4d sites originally occupied by Sn and its interaction with the Mn atoms at other sites decide the stability of the martensitic phases. This explains the discrepancy between the experiments and earlier DFT calculations regarding phase stability in [Formula: see text]NiSn. Our results qualitatively explain the trends observed experimentally with regard to martensitic phase stability and the magnetisations in Ni-excess, Sn-deficient [Formula: see text]NiSn system. PMID- 29185998 TI - Temperature dependent structural evolution in liquid Ag50Ga50 alloy. AB - The temperature dependence of atomic structural evolution in liquid Ag50Ga50 alloy has been studied using an in situ high energy x-ray diffraction (XRD) experiment combined with first-principles molecular dynamics (FPMD) simulations. The experimental data show a reversible structural crossover at the temperature of about 1050 K. Changes in both electrical resistivity and absolute thermoelectric power at about 1100 K strongly support the XRD results. Additionally, FPMD simulations reveal the abnormal temperature dependent behavior of partial coordination number and atomic diffusivity at about 1200 K, elucidating that the partition experimentally observed changes in structure and properties could be linked with the repartition between Ag and Ga atoms in the liquid at around 1050-1200 K. This finding will trigger more studies on the structural evolution of noble-polyvalent metals in particular and metallic liquids in general. PMID- 29185999 TI - Demagnetizing fields in all-optical switching. AB - A model of demagnetizing fields and micromagnetic simulations are applied to examine the evolution of a demagnetized cylinder. In addition to three expected final magnetic structures, a fourth switched state is obtained over a range of magnetic energy densities. The switched state is absent when demagnetizing fields are neglected. The connection to all-optical switching of materials with perpendicular magnetic anisotropy is discussed. PMID- 29186000 TI - Effect of Pt and Au current collector in LiMn2O4 thin film for micro-batteries. AB - The crystal orientation and morphology of sputtered LiMn2O4 thin films is strongly affected by the current collector. By substituting Pt with Au, it is possible to observe in the x-ray diffraction pattern of LiMn2O4 a change in the preferential orientation of the grains from (111) to (400). In addition, LiMn2O4 thin films deposited on Au show a higher porosity than films deposited on Pt. These structural differences cause an improvement in the electrochemical performances of the thin films deposited on Au, with up to 50% more specific charge. Aqueous cells using thin film based on LiMn2O4 sputtered on Au or Pt as the cathode electrode present a similar retention of specific charge, delivering 85% and 100%, respectively, of the initial values after 100 cycles. The critical role of the nature of the substrate used in the morphology and electrochemical behaviour observed could permit the exploration of similar effects for other lithium intercalation electrodes. PMID- 29186001 TI - Dynamic electron-ion collisions and nuclear quantum effects in quantum simulation of warm dense matter. AB - The structural, thermodynamic and transport properties of warm dense matter (WDM) are crucial to the fields of astrophysics and planet science, as well as inertial confinement fusion. WDM refers to the states of matter in a regime of temperature and density between cold condensed matter and hot ideal plasmas, where the density is from near-solid up to ten times solid density, and the temperature between 0.1 and 100 eV. In the WDM regime, matter exhibits moderately or strongly coupled, partially degenerate properties. Therefore, the methods used to deal with condensed matter and isolated atoms need to be properly validated for WDM. It is therefore a big challenge to understand WDM within a unified theoretical description with reliable accuracy. Here, we review the progress in the theoretical study of WDM with state-of-the-art simulations, i.e. quantum Langevin molecular dynamics and first principles path integral molecular dynamics. The related applications for WDM are also included. PMID- 29186002 TI - Spin Hall magnetoresistance in the non-collinear ferrimagnet GdIG close to the compensation temperature. AB - We investigate the spin Hall magnetoresistance (SMR) in a gadolinium iron garnet (GdIG)/platinum (Pt) heterostructure by angular dependent magnetoresistance measurements. The magnetic structure of the ferromagnetic insulator GdIG is non collinear near the compensation temperature, while it is collinear far from the compensation temperature. In the collinear regime, the SMR signal in GdIG is consistent with the usual [Formula: see text] relation well established in the collinear magnet yttrium iron garnet, with [Formula: see text] the angle between magnetization and spin Hall spin polarization direction. In the non-collinear regime, both an SMR signal with inverted sign and a more complex angular dependence with four maxima are observed within one sweep cycle. The number of maxima as well as the relative strength of different maxima depend strongly on temperature and field strength. Our results evidence a complex SMR behavior in the non-collinear magnetic regime that goes beyond the conventional formalism developed for collinear magnetic structures. PMID- 29186003 TI - Magnetic behavior of metastable Fe films grown on Ir(1 1 1). AB - We investigated the growth of ultra-thin Fe films on Ir(1 1 1) by means of in situ low energy electron diffraction and spin-resolved photoemission techniques. We observe a (1 * 1) diffraction pattern, characteristic of the fcc substrate, below four monolayers (ML). Then, a complex superstructure starts to develop, compatible with the formation of bcc-like Fe domains aligned with the substrate according to the Kourdjumov-Sachs orientation relationships. The analysis of the diffraction patterns reveals a progressive evolution towards a fully relaxed bcc lattice, characteristic of bulk Fe. Both photoemission (filled states) and inverse photoemission (empty states) results show characteristic features related to the contribution of the Fe layer, evolving towards those observed on the Fe (1 1 0) bcc surface. Spin resolution allows to detect a spectral polarization above 4 ML, corresponding to the formation of bcc Fe, which gradually increases indicating the formation of an in-plane magnetized ferromagnetic layer in thick films. No in-plane net magnetization is detected in thinner films, independent of the sample temperature down to 30 K. Following recent investigations on the Fe/Ir(1 1 1) system with microscopy techniques, we link this observation to the stabilization of a non collinear spin structure yielding an overall nil magnetization. PMID- 29186004 TI - Pressure dependence of Ce valence in CeRhIn5. AB - We have studied the Ce valence as a function of pressure in CeRhIn5 at 300 K and at 22 K using x-ray absorption spectroscopy in partial fluorescent yield mode. At room temperature, we found no detectable change in Ce valence greater than 0.01 up to a pressure of 5.5 GPa. At 22 K, the valence remains robust against pressure below 6GPa, in contrast to the predicted valence crossover at P=2.35 GPa. This work yields an upper limit for the change in Ce valence and suggests that the critical valence fluctuation scenario, in its current form, is unlikely. PMID- 29186005 TI - Intense blue upconversion emission and intrinsic optical bistability in Tm3+/Yb3+/Zn2+ tridoped YVO4 phosphors. AB - Tm3+/Yb3+/Zn2+:yttrium metavanadate (YVO4) phosphors prepared through chemical coprecipitation and the solid state reaction method have been structurally characterized by an x-ray diffraction (XRD) study. Photoluminescence study of the developed phosphors under ultraviolet (UV) and near infrared (NIR) excitation has been performed. The excitation spectrum of the tetragonal zircon type YVO4 phosphors corresponding to the emission at ~476 nm exhibits a broad excitation peak in the 250-350 nm region, which is due to charge distribution in the [Formula: see text] group. Under 980 nm CW diode laser excitation, enhancements of about ~3000 times and ~40 times have been observed for the blue band in the tridoped Tm3+Yb3+Zn2+:YVO4 phosphors compared to those of the Tm3+:YVO4 singly and Tm3+/Yb3+:YVO4 codoped phosphors, respectively. A downconversion (DC) emission study shows an enhancement of about ~50 times for the blue band in the tridoped phosphors compared to that of the singly doped phosphors. Optical bistability (OB) behavior of the developed phosphors has been also investigated upon 980 nm excitation. The calculated Commission Internationale de l'Eclairage (CIE) color coordinates lie in the blue region with 96.5% color purity under 980 nm excitation, having a color temperature of ~3400 K. Our observations show that the developed phosphors may be suitably used in dual mode luminescence spectroscopy, display devices, and UV LED chips. PMID- 29186006 TI - Field-tuned superconductor-insulator transitions and Hall resistance in thin polycrystalline MoN films. AB - We report on the superconductor-insulator transitions (SITs) of disordered molybdenum nitride (MoN) thin films on (1 0 0) MgO substrates as a function of the film thickness and magnetic fields. The T c of the superconducting MoN films, which exhibit a sharp superconducting transition, monotonically decreases as the normal state R sq increases with a decreasing film thickness. For several films with different thicknesses, we estimate the critical field H c and the product znu ? 0.6 of the dynamical exponent z and the correlation length exponent nu using a finite scaling analysis. The value of this product can be explained by the (2 + 1) XY model. We found that the Hall resistance DeltaR xy (H) is maximized when the magnetic field satisfies H HP(T) [Formula: see text] |1 - T/T C0| in the superconducting state and also in the normal states owning to the superconducting fluctuation corresponding to the ghost critical magnetic field. We measured the Hall conductivity deltasigma xy (H) = sigma xy (H) - [Formula: see text] and fit the Gaussian approximation theory for deltasigma xy (H) to the experimental data. Agreement between the data and the theory beyond H c suggests the survival of the Cooper pair in the insulating region of the SIT. PMID- 29186007 TI - Anatomically realistic ultrasound phantoms using gel wax with 3D printed moulds. AB - Here we describe methods for creating tissue-mimicking ultrasound phantoms based on patient anatomy using a soft material called gel wax. To recreate acoustically realistic tissue properties, two additives to gel wax were considered: paraffin wax to increase acoustic attenuation, and solid glass spheres to increase backscattering. The frequency dependence of ultrasound attenuation was well described with a power law over the measured range of 3-10 MHz. With the addition of paraffin wax in concentrations of 0 to 8 w/w%, attenuation varied from 0.72 to 2.91 dB cm-1 at 3 MHz and from 6.84 to 26.63 dB cm-1 at 10 MHz. With solid glass sphere concentrations in the range of 0.025-0.9 w/w%, acoustic backscattering consistent with a wide range of ultrasonic appearances was achieved. Native gel wax maintained its integrity during compressive deformations up to 60%; its Young's modulus was 17.4 +/- 1.4 kPa. The gel wax with additives was shaped by melting and pouring it into 3D printed moulds. Three different phantoms were constructed: a nerve and vessel phantom for peripheral nerve blocks, a heart atrium phantom, and a placental phantom for minimally-invasive fetal interventions. In the first, nerves and vessels were represented as hyperechoic and hypoechoic tubular structures, respectively, in a homogeneous background. The second phantom comprised atria derived from an MRI scan of a patient with an intervening septum and adjoining vena cavae. The third comprised the chorionic surface of a placenta with superficial fetal vessels derived from an image of a post-partum human placenta. Gel wax is a material with widely tuneable ultrasound properties and mechanical characteristics that are well suited for creating patient-specific ultrasound phantoms in several clinical disciplines. PMID- 29186008 TI - PET attenuation correction for flexible MRI surface coils in hybrid PET/MRI using a 3D depth camera. AB - PET attenuation correction for flexible MRI radio frequency surface coils in hybrid PET/MRI is still a challenging task, as position and shape of these coils conform to large inter-patient variabilities. The purpose of this feasibility study is to develop a novel method for the incorporation of attenuation information about flexible surface coils in PET reconstruction using the Microsoft Kinect V2 depth camera. The depth information is used to determine a dense point cloud of the coil's surface representing the shape of the coil. From a CT template-acquired once in advance-surface information of the coil is extracted likewise and converted into a point cloud. The two point clouds are then registered using a combination of an iterative-closest-point (ICP) method and a partially rigid registration step. Using the transformation derived through the point clouds, the CT template is warped and thereby adapted to the PET/MRI scan setup. The transformed CT template is converted into an attenuation map from Hounsfield units into linear attenuation coefficients. The resulting fitted attenuation map is then integrated into the MRI-based patient-specific DIXON based attenuation map of the actual PET/MRI scan. A reconstruction of phantom PET data acquired with the coil present in the field-of-view (FoV), but without the corresponding coil attenuation map, shows large artifacts in regions close to the coil. The overall count loss is determined to be around 13% compared to a PET scan without the coil present in the FoV. A reconstruction using the new MU-map resulted in strongly reduced artifacts as well as increased overall PET intensities with a remaining relative difference of about 1% to a PET scan without the coil in the FoV.

AB - Formation of the highly-ordered [Formula: see text]-periodicity 2D compound has been detected in the (Tl, Au)/Si(1 1 1) system as a result of Au deposition onto the Tl/Si(1 1 1) surface, its composition, structure and electronic properties have been characterized using scanning tunneling microscopy, angle-resolved photoelectron spectroscopy and density-functional-theory calculations. On the basis of these data, the structural model of the Tl-Au compound has been proposed, which adopts 12 Tl atoms and 10 Au atoms (in total, 22 atoms) per [Formula: see text] unit cell, i.e. ~1.71 ML of Tl and ~1.43 ML of Au (in total, ~3.14 ML). Qualitatively, the model can be visualized as consisting of truncated-pyramid-like Au clusters with a Tl atom on top, while the other Tl atoms form a double layer around the Au clusters. The (Tl, Au)/Si(1 1 1)[Formula: see text] compound has been found to exhibit pronounced metallic properties at least down to temperatures as low as ~25 K, which makes it a promising object for studying electrical transport phenomena in the 2D metallic systems. PMID- 29186010 TI - Unidirectional lateral nanowire formation during the epitaxial growth of GaAsBi on vicinal substrates. AB - We report on enhanced control of the growth of lateral GaAs nanowires (NWs) embedded in epitaxial (100) GaAsBi thin films enabled by the use of vicinal substrates and the growth-condition dependent role of Bi as a surfactant. Enhanced step-flow growth is achieved through the use of vicinal substrates and yields unidirectional nanowire growth. The addition of Bi during GaAsBi growth enhances Ga adatom diffusion anisotropy and modifies incorporation rates at steps in comparison to GaAs growth yielding lower density but longer NWs. The NWs grown on vicinal substrates grew unidirectionally towards the misorientation direction when Bi was present. The III/V flux ratio significantly impacts the size, shape and density of the resulting NWs. These results suggest that utilizing growth conditions which enhance step-flow growth enable enhanced control of lateral nanostructures. PMID- 29186011 TI - Using biomaterials to promote pro-regenerative glial phenotypes after nervous system injuries. AB - Trauma to either the central or peripheral nervous system (PNS) often leads to significant loss of function and disability in patients. This high rate of long term disability is due to the overall limited regenerative potential of nervous tissue, even though the PNS has more regenerative potential than the central nervous system (CNS). The supporting glial cells in the periphery, Schwann cells, are part of the reason for the improved recovery observed in the PNS. In the CNS, the glial populations, astrocytes and oligodendrocytes (OLs), do not have as much potential to promote regeneration and are at times inhibitory to neuronal growth. In particular, the inhibitory roles astrocytes play following trauma has led to a historical focus on neurons and OLs instead of astrocytes. Recently, this focus has shifted as new, regenerative astrocyte phenotypes have been described. From these observations, glial cells clearly play critical roles in native recovery pathways in both the CNS and PNS. This makes the ability to manipulate both transplanted and native glial cell phenotypes a potentially successful strategy to improve nerve injury outcomes. This review focuses on factors that cause glial cells to adopt repair phenotypes and biomaterials that manipulate and/or harness these glial phenotypes. PMID- 29186012 TI - Transparent Electrode Based on Silver Nanowires and Polyimide for Film Heater and Flexible Solar Cell. AB - Transparent, conductive, and flexible Ag nanowire (NW)-polyimide (PI) composite films were fabricated by a facile solution method. Well-dispersed Ag NWs result in percolation networks on the PI supporting layer. A series of films with transmittance values of 53-80% and sheet resistances of 2.8-16.5 Omega/sq were investigated. To further verify the practicability of the Ag NWs-PI film in optoelectronic devices, we utilized it in a film heater and a flexible solar cell. The film heater was able to generate a temperature of 58 degrees C at a driving voltage of 3.5 V within 20 s, indicating its potential application in heating devices that require low power consumption and fast response. The flexible solar cell based on the composite film with a transmittance value of 71% presented a power conversion efficiency of 3.53%. These successful applications proved that the fabricated Ag NWs-PI composite film is a good candidate for application in flexible optoelectronic devices. PMID- 29186014 TI - Comprehensive Detection of Gas Plumes from Multibeam Water Column Images with Minimisation of Noise Interferences. AB - Multibeam echosounder systems (MBES) can record backscatter strengths of gas plumes in the water column (WC) images that may be an indicator of possible occurrence of gas at certain depths. Manual or automatic detection is generally adopted in finding gas plumes, but frequently results in low efficiency and high false detection rates because of WC images that are polluted by noise. To improve the efficiency and reliability of the detection, a comprehensive detection method is proposed in this paper. In the proposed method, the characteristics of WC background noise are first analyzed and given. Then, the mean standard deviation threshold segmentations are respectively used for the denoising of time-angle and depth-angle images, an intersection operation is performed for the two segmented images to further weaken noise in the WC data, and the gas plumes in the WC data are detected from the intersection image by the morphological constraint. The proposed method was tested by conducting shallow-water and deepwater experiments. In these experiments, the detections were conducted automatically and higher correct detection rates than the traditional methods were achieved. The performance of the proposed method is analyzed and discussed. PMID- 29186013 TI - Improving the Accessibility and Efficiency of Point-of-Care Diagnostics Services in Low- and Middle-Income Countries: Lean and Agile Supply Chain Management. AB - Access to point-of-care (POC) diagnostics services is essential for ensuring rapid disease diagnosis, management, control, and surveillance. POC testing services can improve access to healthcare especially where healthcare infrastructure is weak and access to quality and timely medical care is a challenge. Improving the accessibility and efficiency of POC diagnostics services, particularly in resource-limited settings, may be a promising route to improving healthcare outcomes. In this review, the accessibility of POC testing is defined as the distance/proximity to the nearest healthcare facility for POC diagnostics service. This review provides an overview of the impact of POC diagnostics on healthcare outcomes in low- and middle-income countries (LMICs) and factors contributing to the accessibility of POC testing services in LMICs, focusing on characteristics of the supply chain management and quality systems management, characteristics of the geographical location, health infrastructure, and an enabling policy framework for POC diagnostics services. Barriers and challenges related to the accessibility of POC diagnostics in LMICs were also discussed. Bearing in mind the reported barriers and challenges as well as the disease epidemiology in LMICs, we propose a lean and agile supply chain management framework for improving the accessibility and efficiency of POC diagnostics services in these settings. PMID- 29186015 TI - Establishing Genotype-to-Phenotype Relationships in Bacteria Causing Hospital Acquired Pneumonia: A Prelude to the Application of Clinical Metagenomics. AB - Clinical metagenomics (CMg), referred to as the application of next-generation sequencing (NGS) to clinical samples, is a promising tool for the diagnosis of hospital-acquired pneumonia (HAP). Indeed, CMg allows identifying pathogens and antibiotic resistance genes (ARGs), thereby providing the information required for the optimization of the antibiotic regimen. Hence, provided that CMg would be faster than conventional culture, the probabilistic regimen used in HAP could be tailored faster, which should lead to an expected decrease of mortality and morbidity. While the inference of the antibiotic susceptibility testing from metagenomic or even genomic data is challenging, a limited number of antibiotics are used in the probabilistic regimen of HAP (namely beta-lactams, aminoglycosides, fluoroquinolones, glycopeptides and oxazolidinones). Accordingly, based on the perspective of applying CMg to the early diagnostic of HAP, we aimed at reviewing the performances of whole genomic sequencing (WGS) of the main HAP-causing bacteria (Enterobacteriaceae, Pseudomonas aeruginosa, Acinetobacter baumannii, Stenotrophomonas maltophilia and Staphylococcus aureus) for the prediction of susceptibility to the antibiotic families advocated in the probabilistic regimen of HAP. PMID- 29186016 TI - The Moderating Effects of Students' Personality Traits on Pro-Environmental Behavioral Intentions in Response to Climate Change. AB - This study developed a model that examined the relationship between undergraduate students' beliefs, norms and pro-environment behavioral intentions in the context of global climate change (GCC). The model was further evaluated to determine whether latent variables, such as sustainability value, environmental concern, social norms, perceived risk, pro-environmental attitude, as defined by the theory of planned behavior and value-belief-norm theory, significantly influenced students' intentions towards pro-environmental behavior. The research model was empirically tested using data collected form 275 undergraduate students. Empirical results found support for four interaction effects of personality traits and the related latent variables of environmental attitude, including sustainability value, social norms, environmental concern and perceived risk. The impact of undergraduate students' environmental attitudes was moderated by personality traits. The findings of this research offer policy makers and enterprises better understandings of undergraduate students' attitudes and behavioral intentions towards GCC and promote the visibility of this issue. PMID- 29186017 TI - Effect of Food Residues in Biofilm Formation on Stainless Steel and Polystyrene Surfaces by Salmonella enterica Strains Isolated from Poultry Houses. AB - Salmonella spp. is a major food-borne pathogen around the world. The ability of Salmonella to produce biofilm is one of the main obstacles in reducing the prevalence of these bacteria in the food chain. Most of Salmonella biofilm studies found in the literature used laboratory growth media. However, in the food chain, food residues are the principal source of nutrients of Salmonella. In this study, the biofilm formation, morphotype, and motility of 13 Salmonella strains belonging to three different subspecies and isolated from poultry houses was evaluated. To simulate food chain conditions, four different growth media (Tryptic Soy Broth at 1/20 dilution, milk at 1/20 dilution, tomato juice, and chicken meat juice), two different surfaces (stainless steel and polystyrene) and two temperatures (6 degrees C and 22 degrees C) were used to evaluate the biofilm formation. The morphotype, motility, and biofilm formation of Salmonella was temperature-dependent. Biofilm formation was significantly higher with 1/20 Tryptic Soy Broth in all the surfaces and temperatures tested, in comparison with the other growth media. The laboratory growth medium 1/20 Tryptic Soy Broth enhanced biofilm formation in Salmonella. This could explain the great differences in biofilm formation found between this growth medium and food residues. However, Salmonella strains were able to produce biofilm on the presence of food residues in all the conditions tested. Therefore, the Salmonella strain can use food residues to produce biofilm on common surfaces of the food chain. More studies combining more strains and food residues are necessary to fully understand the mechanism used by Salmonella to produce biofilm on the presence of these sources of nutrients.

AB - Broiler meat can become contaminated with Campylobacter of intestinal origin during processing. The present study aimed to identify the prevalence of Campylobacter in broiler flocks and meat contamination at retail shops, and determine the influence of semi-automated and wet market processing on Campylobacter contamination of neck skin samples. Samples were collected from semi-automated plants (n = 102) and wet markets (n = 25). From each batch of broilers, pooled caecal samples and neck skin samples were tested for Campylobacter. Broiler meat purchased from retail outlets (n = 37) was also tested. The prevalence of Campylobacter colonized broiler flocks was 67%. The contamination of meat at retail was 59%. Both semi-automated and wet market processing resulted to contaminate the broiler neck skins to the levels of 27.4% and 48%, respectively. When Campylobacter-free broiler flocks were processed in semi-automated facilities 15% (5/33) of neck skin samples became contaminated by the end of processing whereas 25% (2/8) became contaminated after wet market processing. Characterization of isolates revealed a higher proportion of C. coli compared to C. jejuni. Higher proportions of isolates were resistant to important antimicrobials. This study shows the importance of Campylobacter in poultry industry in Sri Lanka and the need for controlling antimicrobial resistance.

AB - Carbon nanoparticles suspension injection (CNSI) has been widely used in tumor drainage lymph node mapping, and its new applications in drug delivery, photothermal therapy, and so on have been extensively investigated. To develop new clinical applications, the toxicity of CNSI after intravenous exposure should be thoroughly investigated to ensure its safe use. Herein, we studied the bioaccumulation of CNSI in reticuloendothelial system (RES) organs and the corresponding toxicity to mice. After the intravenous injection of CNSI, no abnormal behavior of mice was observed during the 28-day observation period. The body weight increases were similar among the exposed groups and the control group. The parameters of hematology and serum biochemistry remained nearly unchanged, with very few of them showing significant changes. The low toxicity of CNSI was also reflected by the unchanged histopathological characteristics of these organs. The injection of CNSI did not induce higher apoptosis levels either. The slight oxidative stress was observed in RES organs at high dosages at day 7 post-exposure. The implication to the clinical applications and toxicological evaluations of carbon nanomaterials is discussed.

AB - The spreading of urban areas and the growth of human population worldwide raise societal and environmental concerns. To better address these concerns, the monitoring of the acoustic environment in urban as well as rural or wilderness areas is an important matter. Building on the recent development of low cost hardware acoustic sensors, we propose in this paper to consider a sensor grid approach to tackle this issue. In this kind of approach, the crucial question is the nature of the data that are transmitted from the sensors to the processing and archival servers. To this end, we propose an efficient audio coding scheme based on third octave band spectral representation that allows: (1) the estimation of standard acoustic indicators; and (2) the recognition of acoustic events at state-of-the-art performance rate. The former is useful to provide quantitative information about the acoustic environment, while the latter is useful to gather qualitative information and build perceptually motivated indicators using for example the emergence of a given sound source. The coding scheme is also demonstrated to transmit spectrally encoded data that, reverted to the time domain using state-of-the-art techniques, are not intelligible, thus protecting the privacy of citizens.

AB - The depressant beta toxin anti-neuroexcitation peptide (ANEP) from the Chinese scorpion Buthus martensii Karsch has analgesic activity by interacting with receptor site 4 of the voltage-gated sodium channels (VGSCs). Here, with molecular dynamics simulations, we examined the binding modes between ANEP and the site 4 of mice sodium channel 1.7 (mNav1.7), a subtype of VGSCs related to peripheral pain. Homology modeling, molecular mechanics, and molecular dynamics in the biomembrane environment were adopted. The results suggested that ANEP bound to the resting site 4 mainly by amino acid residues in the beta2-beta3 loop and the 'NC' domains, and the activate site 4 mainly by amino acid residues in the hydrophobic domain of N-groove and residues in the 'pharmacophore'. Effects analysis of 14 mutants in the predicted functional domains of ANEP on mouse twisting models showed that the analgesic activity of mutants L15 and E24 of the 'pharmacophore', W36, T37, W38, and T39 forming the loop between the beta2- and beta3-strands and N8, V12, C60, and K64 in the NC domain increased distinctly after these residues were substituted for Ala, respectively. The binding modes and the active sites predicted were consistent with available mutagenesis data, and which is meaningful to understand the related mechanisms of ANEP for Nav1.7.

AB - This paper presents a highly sensitive flexural plate-wave (FPW)-based microsystem for rapid detection of tetrahydrocannabinol (THC) in human urine. First, a circular-type interdigital transducer (IDT) was integrated with a circular-type silicon-grooved reflective grating structure (RGS) to reduce insertion loss. Then, with lower insertion loss (-38.758 dB), the FPW device was used to develop a novel THC biosensor, and the results reveal that this FPW-THC biosensor has low detection limit (1.5625 ng/mL) and high mass-sensitivity (126.67 cm2/g). Finally, this biosensor was integrated with field-programmable gate array (FPGA) board and discrete components for prototyping a FPW readout system, whose maximum error was 12.378 kHz to ensure that the linearity of detection up to R-square is equal to 0.9992. PMID- 29186020 TI - Applications of Alternative Nucleases in the Age of CRISPR/Cas9. AB - Breakthroughs in the development of programmable site-specific nucleases, including zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), meganucleases (MNs), and most recently, the clustered regularly interspaced short palindromic repeats (CRISPR) associated proteins (including Cas9) have greatly enabled and accelerated genome editing. By targeting double-strand breaks to user-defined locations, the rates of DNA repair events are greatly enhanced relative to un-catalyzed events at the same sites. However, the underlying biology of each genome-editing nuclease influences the targeting potential, the spectrum of off-target cleavages, the ease-of-use, and the types of recombination events at targeted double-strand breaks. No single genome-editing nuclease is optimized for all possible applications. Here, we focus on the diversity of nuclease domains available for genome editing, highlighting biochemical properties and the potential applications that are best suited to each domain. PMID- 29186024 TI - Gold Nanoparticles Used as Protein Scavengers Enhance Surface Plasmon Resonance Signal. AB - Although several researchers had reported on methodologies for surface plasmon resonance (SPR) signal amplification based on the use of nanoparticles (NPs), the majority addressed the sandwich technique and low protein concentration. In this work, a different approach for SPR signal enhancement based on the use of gold NPs was evaluated. The method was used in the detection of two lectins, peanut agglutinin (PNA) and concanavalin A (ConA). Gold NPs were functionalized with antibodies anti-PNA and anti-ConA, and these NPs were used as protein scavengers in a solution. After being incubated with solutions of PNA or ConA, the gold NPs coupled with the collected lectins were injected on the sensor containing the immobilized antibodies. The signal amplification provided by this method was compared to the signal amplification provided by the direct coupling of PNA and ConA to gold NPs. Furthermore, both methods, direct coupling and gold NPs as protein scavengers, were compared to the direct detection of PNA and ConA in solution. Compared to the analysis of free protein, the direct coupling of PNA and ConA to gold NPs resulted in a signal amplification of 10-40-fold and a 13 fold decrease of the limit of detection (LOD), whereas the use of gold NPs as protein scavengers resulted in an SPR signal 40-50-times higher and an LOD 64 times lower. PMID- 29186025 TI - Effect of CaO on NOx Reduction by Selective Non-Catalytic Reduction under Variable Gas Compositions in a Simulated Cement Precalciner Atmosphere. AB - High-concentration CaO particles and gas compositions have a significant influence on NOx reduction by selective non-catalytic reduction (SNCR) in cement precalciners. The effect of gas composition on NOx reduction by SNCR with NH3 was studied in a cement precalciner atmosphere with and without CaO at 700-1100 degrees C. It was found that CaO significantly lowers NOx reduction efficiency between 750 degrees C and 1000 degrees C, which is attributed to the catalytic oxidation of NH3 to NO. Although increasing NH3 concentration was advantageous to NOx reduction, the existence of CaO led to the opposite result at 750-900 degrees C. Adding H2O can suppress the negative effect of CaO on NOx reduction. Decreasing O2 content from 10% to 1% shifts the temperature range in which CaO has a significant effect from 750-1000 degrees C to 800-1050 degrees C. CO has a variety of influences on the CaO effect under different experimental conditions. The influences of NH3, H2O, O2, and CO on the effect of CaO can be attributed to the impacts of the gas compositions on gas-phase NH3 conversion, gas-solid catalytic NH3 oxidation, or both processes. A proposed pathway for the effect of gas compositions on NOx reduction in CaO-containing SNCR process was developed that well predicted the CaO-containing SNCR process. PMID- 29186026 TI - Antimicrobial Activity of Bee Venom and Melittin against Borrelia burgdorferi. AB - Lyme disease is a tick-borne, multi-systemic disease, caused by the bacterium Borrelia burgdorferi. Though antibiotics are used as a primary treatment, relapse often occurs after the discontinuation of antimicrobial agents. The reason for relapse remains unknown, however previous studies suggest the possible presence of antibiotic resistant Borrelia round bodies, persisters and attached biofilm forms. Thus, there is an urgent need to find antimicrobial agents suitable to eliminate all known forms of B. burgdorferi. In this study, natural antimicrobial agents such as Apis mellifera venom and a known component, melittin, were tested using SYBR Green I/PI, direct cell counting, biofilm assays combined with LIVE/DEAD and atomic force microscopy methods. The obtained results were compared to standalone and combinations of antibiotics such as Doxycycline, Cefoperazone, Daptomycin, which were recently found to be effective against Borrelia persisters. Our findings showed that both bee venom and melittin had significant effects on all the tested forms of B. burgdorferi. In contrast, the control antibiotics when used individually or even in combinations had limited effects on the attached biofilm form. These findings strongly suggest that whole bee venom or melittin could be effective antimicrobial agents for B. burgdorferi; however, further research is necessary to evaluate their effectiveness in vivo, as well as their safe and effective delivery method for their therapeutic use. PMID- 29186027 TI - A New Low-Temperature Electrochemical Hydrocarbon and NOx Sensor. AB - In this article, a new investigation on a low-temperature electrochemical hydrocarbon and NOx sensor is presented. Based on the mixed-potential-based sensing scheme, the sensor is constructed using platinum and metal oxide electrodes, along with an Yttria-Stabilized Zirconia (YSZ)/Strontium Titanate (SrTiO3) thin-film electrolyte. Unlike traditional mixed-potential sensors which operate at higher temperatures (>400 degrees C), this potentiometric sensor operates at 200 degrees C with dominant hydrocarbon (HC) and NOx response in the open-circuit and biased modes, respectively. The possible low-temperature operation of the sensor is speculated to be primarily due to the enhanced oxygen ion conductivity of the electrolyte, which may be attributed to the space charge effect, epitaxial strain, and atomic reconstruction at the interface of the YSZ/STO thin film. The response and recovery time for the NOx sensor are found to be 7 s and 8 s, respectively. The sensor exhibited stable response even after 120 days of testing, with an 11.4% decrease in HC response and a 3.3% decrease in NOx response. PMID- 29186028 TI - Responsive Proteins in Wheat Cultivars with Contrasting Nitrogen Efficiencies under the Combined Stress of High Temperature and Low Nitrogen. AB - Productivity of wheat (Triticumaestivum) is markedly affected by high temperature and nitrogen deficiency. Identifying the functional proteins produced in response to these multiple stresses acting in a coordinated manner can help in developing tolerance in the crop. In this study, two wheat cultivars with contrasting nitrogen efficiencies (N-efficient VL616 and N-inefficient UP2382) were grown in control conditions, and under a combined stress of high temperature (32 degrees C) and low nitrogen (4 mM), and their leaf proteins were analysed in order to identify the responsive proteins. Two-dimensional electrophoresis unravelled sixty-one proteins, which varied in their expression in wheat, and were homologous to known functional proteins involved in biosynthesis, carbohydrate metabolism, energy metabolism, photosynthesis, protein folding, transcription, signalling, oxidative stress, water stress, lipid metabolism, heat stress tolerance, nitrogen metabolism, and protein synthesis. When exposed to high temperature in combination with low nitrogen, wheat plants altered their protein expression as an adaptive means to maintain growth. This response varied with cultivars. Nitrogen-efficient cultivars showed a higher potential of redox homeostasis, protein stability, osmoprotection, and regulation of nitrogen levels. The identified stress-responsive proteins can pave the way for enhancing the multiple-stress tolerance in wheat and developing a better understanding of its mechanism. PMID- 29186030 TI - Buprofezin Is Metabolized by CYP353D1v2, a Cytochrome P450 Associated with Imidacloprid Resistance in Laodelphax striatellus. AB - CYP353D1v2 is a cytochrome P450 related to imidacloprid resistance in Laodelphax striatellus. This work was conducted to examine the ability of CYP353D1v2 to metabolize other insecticides. Carbon monoxide difference spectra analysis indicates that CYP353D1v2 was successfully expressed in insect cell Sf9. The catalytic activity of CYP353D1v2 relating to degrading buprofezin, chlorpyrifos, and deltamethrin was tested by measuring substrate depletion and analyzing the formation of metabolites. The results showed the nicotinamide-adenine dinucleotide phosphate (NADPH)-dependent depletion of buprofezin (eluting at 8.7 min) and parallel formation of an unknown metabolite (eluting 9.5 min). However, CYP353D1v2 is unable to metabolize deltamethrin and chlorpyrifos. The recombinant CYP353D1v2 protein efficiently catalyzed the model substrate p-nitroanisole with a maximum velocity of 9.24 nmol/min/mg of protein and a Michaelis constant of Km = 6.21 uM. In addition, imidacloprid was metabolized in vitro by the recombinant CYP353D1v2 microsomes (catalytic constant Kcat) 0.064 pmol/min/pmol P450, Km = 6.41 uM. The mass spectrum of UPLC-MS analysis shows that the metabolite was a product of buprofezin, which was buprofezin sulfone. This result provided direct evidence that L. striatellus cytochrome P450 CYP353D1v2 is capable of metabolizing imidacloprid and buprofezin. PMID- 29186029 TI - MUC1: The First Respiratory Mucin with an Anti-Inflammatory Function. AB - MUC1 is a membrane-bound mucin expressed on the apical surfaces of most mucosal epithelial cells. In normal lung epithelia, MUC1 is a binding site for Pseudomonas aeruginosa, an opportunistic human pathogen of great clinical importance. It has now been established that MUC1 also serves an anti inflammatory role in the airways that is initiated late in the course of a bacterial infection and is mediated through inhibition of Toll-like receptor (TLR) signaling. MUC1 expression was initially shown to interfere with TLR5 signaling in response to P. aeruginosa flagellin, but has since been extended to other TLRs. These new findings point to an immunomodulatory role for MUC1 during P. aeruginosa lung infection, particularly during the resolution phase of inflammation. This review briefly summarizes the recent characterization of MUC1's anti-inflammatory properties in both the respiratory tract and extrapulmonary tissues. PMID- 29186031 TI - Lipopolysaccharide Modifies Glycerol Permeability and Metabolism in 3T3-L1 Adipocytes. AB - Aquaglyceroporins-aquaporin membrane channels (AQP) that conduct glycerol and other small neutral solutes in addition to water-play major roles in obesity. In adipocytes, aquaglyceroporins mediate glycerol uptake and release across the plasma membrane, which are two key steps for triacylglycerols (TAGs) synthesis (lipogenesis) and hydrolysis (lipolysis). The aim of this study was to assess both glycerol permeability and metabolism in undifferentiated 3T3-L1 cells (UDCs) as well as in untreated (CTL-DCs) versus lipopolysaccharide (LPS-DCs)-treated differentiated 3T3-L1 adipocytes. Glycerol release, TAGs content and whole membrane glycerol permeability were significantly increased in DCs as compared to UDCs. Moreover, in DCs, LPS treatment significantly increased TAGs content and decreased glycerol permeability. In addition, a significant reduction in whole membrane glycerol permeability was observed in LPS-DCs as compared to CTL-DCs. The relative contributions of AQP3, AQP7 and AQP9 (facilitated diffusion), as well as that of the phospholipid bilayer (simple diffusion), to the whole membrane glycerol permeability, were estimated biophysically in UDCs, CTL-DCs and LPS-DCs, using selective AQP inhibitors. Further studies will be required to determine if modifications in either subcellular localization and/or activity of aquaglyceroporins could account for the data herein. Nevertheless, our findings provide novel insights in understanding the LPS-induced adipocyte hypertrophy that accompanies obesity.

AB - LCB01-0648 is a novel oxazolidinone compound that shows potent antibacterial activities against most Gram-positive cocci, including the multi-drug resistant Staphylococcusaureus. In this study, in vivo activity of LCB01-0699, a LCB01-0648 prodrug, against S.aureus was evaluated in comparison with that of Linezolid. The results of the systemic infection study demonstrated that LCB01-0699 was more potent than Linezolid against methicillin-susceptible and -resistant S. aureus strains. The in vivo efficacy of LCB01-0699 against methicillin-susceptible and resistant S. aureus strains in a skin infection model showed more potent activity than Linezolid. LCB01-0699 shows potent in vivo activity against methicillin susceptible and -resistant S. aureus strains, suggesting that LCB01-0699 would be a novel candidate for the treatment of these infectious diseases caused by S. aureus. PMID- 29186033 TI - Comparative Flight Activities and Pathogen Load of Two Stocks of Honey Bees Reared in Gamma-Irradiated Combs. AB - Gamma irradiation is known to inactivate various pathogens that negatively affect honey bee health. Bee pathogens, such as Deformed wing virus (DWV) and Nosema spp., have a deleterious impact on foraging activities and bee survival, and have been detected in combs. In this study, we assessed the effects of gamma irradiation on the flight activities, pathogen load, and survival of two honey bee stocks that were reared in irradiated and non-irradiated combs. Overall, bee genotype influenced the average number of daily flights, the total number of foraging flights, and total flight duration, in which the Russian honey bees outperformed the Italian honey bees. Exposing combs to gamma irradiation only affected the age at first flight, with worker bees that were reared in non irradiated combs foraging prematurely compared to those reared in irradiated combs. Precocious foraging may be associated with the higher levels of DWV in bees reared in non-irradiated combs and also with the lower amount of pollen stores in colonies that used non-irradiated combs. These data suggest that gamma irradiation of combs can help minimize the negative impact of DWV in honey bees. Since colonies with irradiated combs stored more pollen than those with non irradiated combs, crop pollination efficiency may be further improved when mite resistant stocks are used, since they performed more flights and had longer flight durations. PMID- 29186035 TI - Are Changes in Neighbourhood Perceptions Associated with Changes in Self-Rated Mental Health in Adults? A 13-Year Repeat Cross-Sectional Study, UK. AB - The aim of this study was to examine changes in neighbourhood perceptions on self rated mental health problems over time, and to explore demographic, geographic and socio-economic factors as determinants of increased or decreased anxiety and depression symptoms. We conducted a repeat cross-sectional study of individuals (N: 4480) living in the same areas of west central Scotland in 1997 and 2010. Individuals were asked to complete a questionnaire at both time-points, containing 14 questions relating to neighbourhood perceptions and the Hospital Anxiety and Depression Scale (HADS). A three-level linear regression model was fitted to HADS scores and changes in neighbourhood perceptions over time; controlling for a number of individual and area-level variables. Overall, area level mean HADS scores decreased from 1997 to 2010. When adjusted for individual and area-level variables, this decrease did not remain for HADS anxiety. Applying an overall 14-scale neighbourhood perception measure, worsening neighbourhood perceptions were associated with small increases in depression (0.04, 95% confidence interval (CI) 0.01 to 0.07) and anxiety (0.04, 95% CI 0.00 to 0.08) scores over time. This highlights a need for local and national policy to target areas where neighbourhood characteristics are substantially deteriorating in order to ensure the mental health of individuals does not worsen.

AB - Although a lot of research has been performed, large segmental bone defects caused by trauma, infection, bone tumors or revision surgeries still represent big challenges for trauma surgeons. New and innovative bone substitutes are needed. Three-dimensional (3D) printing is a novel procedure to create 3D porous scaffolds that can be used for bone tissue engineering. In the present study, solid discs as well as porous cage-like 3D prints made of polylactide (PLA) are coated or filled with collagen, respectively, and tested for biocompatibility and endotoxin contamination. Microscopic analyses as well as proliferation assays were performed using various cell types on PLA discs. Stromal-derived factor (SDF 1) release from cages filled with collagen was analyzed and the effect on endothelial cells tested. This study confirms the biocompatibility of PLA and demonstrates an endotoxin contamination clearly below the FDA (Food and Drug Administration) limit. Cells of various cell types (osteoblasts, osteoblast-like cells, fibroblasts and endothelial cells) grow, spread and proliferate on PLA printed discs. PLA cages loaded with SDF-1 collagen display a steady SDF-1 release, support cell growth of endothelial cells and induce neo-vessel formation. These results demonstrate the potential for PLA scaffolds printed with an inexpensive desktop printer in medical applications, for example, in bone tissue engineering. PMID- 29186037 TI - Symbiotic Sensing for Energy-Intensive Tasks in Large-Scale Mobile Sensing Applications. AB - Energy consumption is a critical performance and user experience metric when developing mobile sensing applications, especially with the significantly growing number of sensing applications in recent years. As proposed a decade ago when mobile applications were still not popular and most mobile operating systems were single-tasking, conventional sensing paradigms such as opportunistic sensing and participatory sensing do not explore the relationship among concurrent applications for energy-intensive tasks. In this paper, inspired by social relationships among living creatures in nature, we propose a symbiotic sensing paradigm that can conserve energy, while maintaining equivalent performance to existing paradigms. The key idea is that sensing applications should cooperatively perform common tasks to avoid acquiring the same resources multiple times. By doing so, this sensing paradigm executes sensing tasks with very little extra resource consumption and, consequently, extends battery life. To evaluate and compare the symbiotic sensing paradigm with the existing ones, we develop mathematical models in terms of the completion probability and estimated energy consumption. The quantitative evaluation results using various parameters obtained from real datasets indicate that symbiotic sensing performs better than opportunistic sensing and participatory sensing in large-scale sensing applications, such as road condition monitoring, air pollution monitoring, and city noise monitoring. PMID- 29186034 TI - Cellular and Oxidative Mechanisms Associated with Interleukin-6 Signaling in the Vasculature. AB - Reactive oxygen species, particularly superoxide, promote endothelial dysfunction and alterations in vascular structure. It is increasingly recognized that inflammatory cytokines, such as interleukin-6 (IL-6), contribute to endothelial dysfunction and vascular hypertrophy and fibrosis. IL-6 is increased in a number of cardiovascular diseases, including hypertension. IL-6 is also associated with a higher incidence of future cardiovascular events and all-cause mortality. Both immune and vascular cells produce IL-6 in response to a number of stimuli, such as angiotensin II. The vasculature is responsive to IL-6 produced from vascular and non-vascular sources via classical IL-6 signaling involving a membrane-bound IL-6 receptor (IL-6R) and membrane-bound gp130 via Jak/STAT as well as SHP2 dependent signaling pathways. IL-6 signaling is unique because it can also occur via a soluble IL-6 receptor (sIL-6R) which allows for IL-6 signaling in tissues that do not normally express IL-6R through a process referred to as IL-6 trans signaling. IL-6 signaling mediates a vast array of effects in the vascular wall, including endothelial activation, vascular permeability, immune cell recruitment, endothelial dysfunction, as well as vascular hypertrophy and fibrosis. Many of the effects of IL-6 on vascular function and structure are representative of loss or reductions in nitric oxide (NO) bioavailability. IL-6 has direct effects on endothelial nitric oxide synthase activity and expression as well as increasing vascular superoxide, which rapidly inactivates NO thereby limiting NO bioavailability. The goal of this review is to highlight both the cellular and oxidative mechanisms associated with IL-6-signaling in the vascular wall in general, in hypertension, and in response to angiotensin II. PMID- 29186038 TI - Molecular Screening of 43 Brazilian Families Diagnosed with Leber Congenital Amaurosis or Early-Onset Severe Retinal Dystrophy. AB - Leber congenital amaurosis (LCA) is a severe disease that leads to complete blindness in children, typically before the first year of life. Due to the clinical and genetic heterogeneity among LCA and other retinal diseases, providing patients with a molecular diagnosis is essential to assigning an accurate clinical diagnosis. Using our gene panel that targets 300 genes that are known to cause retinal disease, including 24 genes reported to cause LCA, we sequenced 43 unrelated probands with Brazilian ancestry. We identified 42 unique variants and were able to assign a molecular diagnosis to 30/43 (70%) Brazilian patients. Among these, 30 patients were initially diagnosed with LCA or a form of early-onset retinal dystrophy, 17 patients harbored mutations in LCA-associated genes, while 13 patients had mutations in genes that were reported to cause other diseases involving the retina. PMID- 29186039 TI - Health Diagnosis of Major Transportation Infrastructures in Shanghai Metropolis Using High-Resolution Persistent Scatterer Interferometry. AB - Since the Persistent Scatterer Synthetic Aperture Radar (SAR) Interferometry (PSI) technology allows the detection of ground subsidence with millimeter accuracy, it is becoming one of the most powerful and economical means for health diagnosis of major transportation infrastructures. However, structures of different types may suffer from various levels of localized subsidence due to the different structural characteristics and subsidence mechanisms. Moreover, in the complex urban scenery, some segments of these infrastructures may be sheltered by surrounding buildings in SAR images, obscuring the desirable signals. Therefore, the subsidence characteristics on different types of structures should be discussed separately and the accuracy of persistent scatterers (PSs) should be optimized. In this study, the PSI-based subsidence mapping over the entire transportation network of Shanghai (more than 10,000 km) is illustrated, achieving the city-wide monitoring specifically along the elevated roads, ground highways and underground subways. The precise geolocation and structural characteristics of infrastructures were combined to effectively guide more accurate identification and separation of PSs along the structures. The experimental results from two neighboring TerraSAR-X stacks from 2013 to 2016 were integrated by joint estimating the measurements in the overlapping area, performing large-scale subsidence mapping and were validated by leveling data, showing highly consistent in terms of subsidence velocities and time-series displacements. Spatial-temporal subsidence patterns on each type of infrastructures are strongly dependent on the operational durations and structural characteristics, as well as the variation of the foundation soil layers. PMID- 29186040 TI - Silver Nanoparticle Modified Electrode Covered by Graphene Oxide for the Enhanced Electrochemical Detection of Dopamine. AB - Several neurological disorders such as Alzheimer's disease and Parkinson's disease have become a serious impediment to aging people nowadays. One of the efficient methods used to monitor these neurological disorders is the detection of neurotransmitters such as dopamine. Metal materials, such as gold and platinum, are widely used in this electrochemical detection method; however, low sensitivity and linearity at low dopamine concentrations limit the use of these materials. To overcome these limitations, a silver nanoparticle (SNP) modified electrode covered by graphene oxide for the detection of dopamine was newly developed in this study. For the first time, the surface of an indium tin oxide (ITO) electrode was modified using SNPs and graphene oxide sequentially through the electrochemical deposition method. The developed biosensor provided electrochemical signal enhancement at low dopamine concentrations in comparison with previous biosensors. Therefore, our newly developed SNP modified electrode covered by graphene oxide can be used to monitor neurological diseases through electrochemical signal enhancement at low dopamine concentrations. PMID- 29186041 TI - Enhanced Intestinal Permeability of Bufalin by a Novel Bufalin-Peptide-Dendrimer Inclusion through Caco-2 Cell Monolayer. AB - Bufalin (BFL) has excellent physiological activities such as defending tumors, improving cardiac function, and so on. However, due to its poor water-solubility and bioavailability, the clinical application of BFL remains limited. In order to improve bioavailability of BFL, in our previous research, a novel peptide dendrimer (PD) was synthesized and applied to encapsulate BFL. In the present study, we investigate the absorption property and mechanism of BFL in free form and BFL-peptide-dendrimer inclusion (BPDI) delivery system by using the Caco-2 cell monolayer model in vitro. The apparent permeability coefficient (Papp) values of BFL in free or BPDI form were over 1.0 * 10-6 cm/s. Meanwhile, their almost equal bi-directional transport and linear transport percentage with time and concentration course indicated that BFL in both forms was absorbed mainly through passive diffusion. The most important result is that the Papp values of BFL increased about three-fold more BPDI than those of its free form, which indicated the intestinal permeability of BFL could be improved while BFL was encapsulated in BPDI form. Therefore, PD encapsulation may be a potential delivery system to increase the bioavailability of BFL. PMID- 29186043 TI - Trend in H2S Biology and Medicine Research-A Bibliometric Analysis. AB - The biological and medical importance of hydrogen sulfide (H2S) has been recognized for decades. The aim of this bibliometric study is to analyze the quantity and quality of publications in H2S biology and medicine (H2SBM) based on the databases of Web of Science and Google Scholar. A total of 5881 publications published between 1990 and 2016 were analyzed. The number of H2SBM papers published before 2004 was below 100 annually, but thereafter this number rapidly increased and peaked in 2015 with more than 7-fold increase. All publications related to H2SBM research achieved a total h-index of 136 and were cited 123,074 times. The most published disciplines in H2S biomedicine research were the cardiovascular system (8.5%), neuroscience (6.5%), and gastroenterology hepatology (4.7%). The country with the greatest number of publications in the H2SBM research field was the USA with 1765 (30.0%) publications, followed by China with 995 (16.9%) publications and Japan with 555 (9.4%) publications. The top 3 most published institutes were National University of Singapore, Peking University in China, and University of Groningen in Netherlands. Nitric Oxide Biology and Chemistry was the most exploited journal for H2SBM publications with 461 articles, followed by FASEB Journal with 200 publications and Antioxidants Redox Signaling with 116 publications. The most highly cited publications and researchers in H2SBM research were also unmasked from this bibliometric analysis. Collectively, H2SBM publications exhibit a continuous trend of increase, reflecting the increased H2SBM research intensity and diversity globally. PMID- 29186042 TI - 2-Substituted Aniline as a Simple Scaffold for LuxR-Regulated QS Modulation. AB - The ability of the 2-substituted aniline motif to serve as a scaffold for designing potential LuxR-regulated quorum sensing (QS) modulators has been investigated, using docking experiments and biological evaluation of a series of 15 specially synthesized compounds. Aniline, 2-acetyl-aniline and 2-nitroaniline were considered, as well as their N-acylated derivatives. Docking experiments showed that the 2-substituted aniline motif fits within the LuxR binding site at the place of the lactone moiety of AHL, and the biological evaluation revealed QS antagonisitic activity for several compounds, validating the hypothesis that this scaffold acts on QS. Structure activity relationships are discussed regarding interactions with the key residues of the LuxR binding site, showing significant variations in the H-bonding pattern.

AB - Given the importance of heterocycle indole derivatives, much effort has been directed toward the development of methods for functionalization of the indole nucleus at N1 and C3 sites. Moreover, the platinum-catalyzed allyation of nucleophiles was an established and efficient way, which has been applied to medicinal and organic chemistry. In our research, the platinum-catalyzed 2,3 disubstitued indoles with allylic acetates was investigated under different conditions. Herein, we established a simple, convenient, and efficient method, which afforded high yield of allylated indoles. PMID- 29186045 TI - Resveratrol-Induced Effects on Body Fat Differ Depending on Feeding Conditions. AB - Science constantly seeks to identify new molecules that could be used as dietary functional ingredients in the fight against obesity and its co-morbidities. Among them, polyphenols represent a group of molecules of increasing interest. One of the most widely studied polyphenols is resveratrol (trans-3,4',5 trihydroxystilbene), which has been proposed as an "energy restriction mimetic" because it can exert energy restriction-like effects. The aim of this review is to analyze the effects of resveratrol on obesity under different feeding conditions, such as overfeeding, normal feeding, and energy restriction, in animals and humans. The vast majority of the studies reported have addressed the administration of resveratrol to animals alongside an obesogenic diet. Under these experimental conditions usually a decreased body weight amount was found. To date, studies that focus on the effects of resveratrol under normal feeding or energy restriction conditions in animals and humans are scarcer. In these studies no changes in body fat were reported. After analyzing the results obtained under overfeeding, normal feeding, and energy restriction conditions, it can be stated that resveratrol is useful in reducing body fat accumulation, and thus preventing obesity. Nevertheless, for ethical reasons, these results have been obtained in animals. By contrast, there are no evidences showing the usefulness of this phenolic compound in reducing previously accumulated body fat. Consequently, as of yet, there is not scientific support for proposing resveratrol as a new anti obesity treatment tool.

AB - The S-containing heterocyclic compounds benzothiopyrans or thiochromones stand out as having promising biological activities due to their structural relationship with chromones (benzopyrans), which are widely known as privileged scaffolds in medicinal chemistry. In this work, we report the synthesis of 35 thiochromone derivatives and the in vitro antileishmanial and cytotoxic activities. Compounds were tested against intracellular amastigotes of Leishmania panamensis and cytotoxic activity against human monocytes (U-937 ATCC CRL 1593.2). Compounds bearing a vinyl sulfone moiety, 4h, 4i, 4j, 4k, 4l and 4m, displayed the highest antileishmanial activity, with EC50 values lower than 10 MUM and an index of selectivity over 100 for compounds 4j and 4l. When the double bond or the sulfone moiety was removed, the activity decreased. Our results show that thiochromones bearing a vinyl sulfone moiety are endowed with high antileishmanial activity and low cytotoxicity.

AB - Polymer matrix composite materials that can emit radiation in the far-infrared region of the spectrum are receiving increasing attention due to their ability to significantly influence biological processes. This study reports on the far infrared emissivity property of composite films based on far-infrared ceramic powder. X-ray fluorescence spectrometry, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray powder diffractometry were used to evaluate the physical properties of the ceramic powder. The ceramic powder was found to be rich in aluminum oxide, titanium oxide, and silicon oxide, which demonstrate high far-infrared emissivity. In addition, the micromorphology, mechanical performance, dynamic mechanical properties, and far-infrared emissivity of the composite were analyzed to evaluate their suitability for strawberry storage. The mechanical properties of the far-infrared radiation ceramic (cFIR) composite films were not significantly influenced (p >= 0.05) by the addition of the ceramic powder. However, the dynamic mechanical analysis (DMA) properties of the cFIR composite films, including a reduction in damping and shock absorption performance, were significant influenced by the addition of the ceramic powder. Moreover, the cFIR composite films showed high far-infrared emissivity, which has the capability of prolonging the storage life of strawberries. This research demonstrates that cFIR composite films are promising for future applications. PMID- 29186048 TI - Three New Malyngamides from the Marine Cyanobacterium Moorea producens. AB - Three new compounds of the malyngamide series, 6,8-di-O-acetylmalyngamide 2 (1), 6-O-acetylmalyngamide 2 (2), and N-demethyl-isomalyngamide I (3), were isolated from the marine cyanobacterium Moorea producens. Their structures were determined by spectroscopic analysis and chemical derivatization and degradation. These compounds stimulated glucose uptake in cultured L6 myotubes. In particular, 6,8 di-O-acetylmalyngamide 2 (1) showed potent activity and activated adenosine monophosphate-activated protein kinase (AMPK). PMID- 29186051 TI - First Results of Using a UVTron Flame Sensor to Detect Alpha-Induced Air Fluorescence in the UVC Wavelength Range. AB - In this work, a robust stand-off alpha detection method using the secondary effects of alpha radiation has been sought. Alpha particles ionise the surrounding atmosphere as they travel. Fluorescence photons produced as a consequence of this can be used to detect the source of the alpha emissions. This paper details experiments carried out to detect this fluorescence, with the focus on photons in the ultraviolet C (UVC) wavelength range (180-280 nm). A detector, UVTron R9533 (Hamamatsu, 325-6, Sunayama-cho, Naka-ku, Hamamatsu City, Shizuoka Pref., 430-8587, Japan), designed to detect the UVC emissions from flames for fire alarm purposes, was tested in various gas atmospheres with a 210Po alpha source to determine if this could provide an avenue for stand-off alpha detection. The results of the experiments show that this detector is capable of detecting alpha-induced air fluorescence in normal indoor lighting conditions, as the interference from daylight and artificial lighting is less influential on this detection system which operates below the UVA and UVB wavelength ranges (280 315 nm and 315-380 nm respectively). Assuming a standard 1 r 2 drop off in signal, the limit of detection in this configuration can be calculated to be approximately 240 mm, well beyond the range of alpha-particles in air, which indicates that this approach could have potential for stand-off alpha detection. The gas atmospheres tested produced an increase in the detector count, with xenon having the greatest effect with a measured 52% increase in the detector response in comparison to the detector response in an air atmosphere. This type of alpha detection system could be operated at a distance, where it would potentially provide a more cost effective, safer, and faster solution in comparison with traditional alpha detection methods to detect and characterise alpha contamination in nuclear decommissioning and security applications. PMID- 29186049 TI - What Does "the RNA World" Mean to "the Origin of Life"? AB - Corresponding to life's two distinct aspects: Darwinian evolution and self sustainment, the origin of life should also split into two issues: the origin of Darwinian evolution and the arising of self-sustainment. Because the "self sustainment" we concern about life should be the self-sustainment of a relevant system that is "defined" by its genetic information, the self-sustainment could not have arisen before the origin of Darwinian evolution, which was just marked by the emergence of genetic information. The logic behind the idea of the RNA world is not as tenable as it has been believed. That is, genetic molecules and functional molecules, even though not being the same material, could have emerged together in the beginning and launched the evolution-provided that the genetic molecules can "simply" code the functional molecules. However, due to these or those reasons, alternative scenarios are generally much less convincing than the RNA world. In particular, when considering the accumulating experimental evidence that is supporting a de novo origin of the RNA world, it seems now quite reasonable to believe that such a world may have just stood at the very beginning of life on the Earth. Therewith, we acquire a concrete scenario for our attempts to appreciate those fundamental issues that are involved in the origin of life. In the light of those possible scenes included in this scenario, Darwinian evolution may have originated at the molecular level, realized upon a functional RNA. When two or more functional RNAs emerged, for their efficient cooperation, there should have been a selective pressure for the emergence of protocells. But it was not until the appearance of the "unitary-protocell", which had all of its RNA genes linked into a chromosome, that Darwinian evolution made its full step towards the cellular level-no longer severely constrained by the low-grade evolution at the molecular level. Self-sustainment did not make sense before protocells emerged. The selection pressure that was favoring the exploration of more and more fundamental raw materials resulted in an evolutionary tendency of life to become more and more self-sustained. New functions for the entities to adapt to environments, including those that are involved in the self-sustainment per se, would bring new burdens to the self-sustainment-the advantage of these functions must overweigh the corresponding disadvantage. PMID- 29186050 TI - HPLC-PDA-MS/MS Characterization of Bioactive Secondary Metabolites from Turraea fischeri Bark Extract and Its Antioxidant and Hepatoprotective Activities In Vivo. AB - Turraea fischeri is an East African traditional herb, which is widely used in traditional medicine. In this study, we profiled the secondary metabolites in the methanol extract of T. fischeri bark using HPLC-PDA-ESI-MS/MS, and 20 compounds were tentatively identified. Several isomers of the flavonolignan cinchonain-I and bis-dihydroxyphenylpropanoid-substituted catechin hexosides dominated the extract. Robust in vitro and in vivo antioxidant properties were observed in 1,1 diphenyl-2-picrylhydrazyl radical scavenging assay (DPPH) and ferric reducing antioxidant power (FRAP) assay, and in the model organism Caenorhabditis elegans. Additionally, the extract exhibited promising hepatoprotective activities in D galactosamine (D-GaIN) treated rats. A significant reduction in the elevated levels of aspartate aminotransferase (AST), total bilirubin, gamma glutamyltransferase (GGT), and malondialdehyde (MDA) and increase of glutathione (GSH) was observed in rats treated with the bark extract in addition to D galactosamine when compared with rats treated with D-galactosamine alone. In conclusion, T. fischeri is apromising candidate for health-promoting and for pharmaceutical applications. PMID- 29186052 TI - Cancer Classification Based on Support Vector Machine Optimized by Particle Swarm Optimization and Artificial Bee Colony. AB - Intelligent optimization algorithms have advantages in dealing with complex nonlinear problems accompanied by good flexibility and adaptability. In this paper, the FCBF (Fast Correlation-Based Feature selection) method is used to filter irrelevant and redundant features in order to improve the quality of cancer classification. Then, we perform classification based on SVM (Support Vector Machine) optimized by PSO (Particle Swarm Optimization) combined with ABC (Artificial Bee Colony) approaches, which is represented as PA-SVM. The proposed PA-SVM method is applied to nine cancer datasets, including five datasets of outcome prediction and a protein dataset of ovarian cancer. By comparison with other classification methods, the results demonstrate the effectiveness and the robustness of the proposed PA-SVM method in handling various types of data for cancer classification. PMID- 29186053 TI - GelSight: High-Resolution Robot Tactile Sensors for Estimating Geometry and Force. AB - Tactile sensing is an important perception mode for robots, but the existing tactile technologies have multiple limitations. What kind of tactile information robots need, and how to use the information, remain open questions. We believe a soft sensor surface and high-resolution sensing of geometry should be important components of a competent tactile sensor. In this paper, we discuss the development of a vision-based optical tactile sensor, GelSight. Unlike the traditional tactile sensors which measure contact force, GelSight basically measures geometry, with very high spatial resolution. The sensor has a contact surface of soft elastomer, and it directly measures its deformation, both vertical and lateral, which corresponds to the exact object shape and the tension on the contact surface. The contact force, and slip can be inferred from the sensor's deformation as well. Particularly, we focus on the hardware and software that support GelSight's application on robot hands. This paper reviews the development of GelSight, with the emphasis in the sensing principle and sensor design. We introduce the design of the sensor's optical system, the algorithm for shape, force and slip measurement, and the hardware designs and fabrication of different sensor versions. We also show the experimental evaluation on the GelSight's performance on geometry and force measurement. With the high resolution measurement of shape and contact force, the sensor has successfully assisted multiple robotic tasks, including material perception or recognition and in-hand localization for robot manipulation. PMID- 29186054 TI - Implementing a Psychotherapy Service for Medically Unexplained Symptoms in a Primary Care Setting. AB - Medically unexplained symptoms (MUS) are known to be costly, complex to manage and inadequately addressed in primary care settings. In many cases, there are unresolved psychological and emotional processes underlying these symptoms, leaving traditional medical approaches insufficient. This paper details the implementation of an evidence-based, emotion-focused psychotherapy service for MUS across two family medicine clinics. The theory and evidence-base for using Intensive Short-Term Dynamic Psychotherapy (ISTDP) with MUS is presented along with the key service components of assessment, treatment, education and research. Preliminary outcome indicators showed diverse benefits. Patients reported significantly decreased somatic symptoms in the Patient Health Questionnaire-15 (d = 0.4). A statistically significant (23%) decrease in family physicians' visits was found in the 6 months after attending the MUS service compared to the 6 months prior. Both patients and primary care clinicians reported a high degree of satisfaction with the service. Whilst further research is needed, these findings suggest that a direct psychology service maintained within the family practice clinic may assist patient and clinician function while reducing healthcare utilization. Challenges and further service developments are discussed, including the potential benefits of re-branding the service to become a 'Primary Care Psychological Consultation and Treatment Service'. PMID- 29186055 TI - Methods for Involving Older People in Health Research-A Review of the Literature. AB - Demographic change has increased the need for research on healthcare for older people. Recently there has been a growing awareness that research might benefit from actively involving patients and the public in study design and conduct. Besides empowering patients and democratizing research, involvement enhances the quality of research and the development of equitable healthcare solutions. Little is known about how to involve older people. This review aims to support scientists intending to involve older people in health research by systematically identifying and describing studies involving older people and analyzing associated facilitators and challenges. Old people were operationalized as people living with old-age-related conditions. We conducted a systematic search in PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Cochrane library for the period 2007 to July 2017 and also manually searched reference lists of the nine retrieved articles and other relevant sources. While involvement of older people in research is feasible, specific challenges related to this group need be taken into account. Strategies to enhance effective involvement comprise a thoughtful choice of location, use of visualization and accessible communication, building good relationships and flexible approaches. Further research is needed on the involvement of people in care homes or with vision, hearing or mobility limitations. PMID- 29186057 TI - Development of Spectral Disease Indices for 'Flavescence Doree' Grapevine Disease Identification. AB - Spectral measurements are employed in many precision agriculture applications, due to their ability to monitor the vegetation's health state. Spectral vegetation indices are one of the main techniques currently used in remote sensing activities, since they are related to biophysical and biochemical crop variables. Moreover, they have been evaluated in some studies as potentially beneficial for detecting or differentiating crop diseases. Flavescence Doree (FD) is an infectious, incurable disease of the grapevine that can produce severe yield losses and, hence, compromise the stability of the vineyards. The aim of this study was to develop specific spectral disease indices (SDIs) for the detection of FD disease in grapevines. Spectral signatures of healthy and diseased grapevine leaves were measured with a non-imaging spectro-radiometer at two infection severity levels. The most discriminating wavelengths were selected by a genetic algorithm (GA) feature selection tool, the Spectral Disease Indices (SDIs) are designed by exhaustively testing all possible combinations of wavelengths chosen. The best weighted combination of a single wavelength and a normalized difference is chosen to create the index. The SDIs are tested for their ability to differentiate healthy from diseased vine leaves and they are compared to some common set of Spectral Vegetation Indices (SVIs). It was demonstrated that using vegetation indices was, in general, better than using complete spectral data and that SDIs specifically designed for FD performed better than traditional SVIs in most of cases. The precision of the classification is higher than 90%. This study demonstrates that SDIs have the potential to improve disease detection, identification and monitoring in precision agriculture applications. PMID- 29186056 TI - Comparison of the Binding of Reversible Inhibitors to Human Butyrylcholinesterase and Acetylcholinesterase: A Crystallographic, Kinetic and Calorimetric Study. AB - Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) hydrolyze the neurotransmitter acetylcholine and, thereby, function as coregulators of cholinergic neurotransmission. Although closely related, these enzymes display very different substrate specificities that only partially overlap. This disparity is largely due to differences in the number of aromatic residues lining the active site gorge, which leads to large differences in the shape of the gorge and potentially to distinct interactions with an individual ligand. Considerable structural information is available for the binding of a wide diversity of ligands to AChE. In contrast, structural data on the binding of reversible ligands to BChE are lacking. In a recent effort, an inhibitor competition approach was used to probe the overlap of ligand binding sites in BChE. Here, we extend this study by solving the crystal structures of human BChE in complex with five reversible ligands, namely, decamethonium, thioflavin T, propidium, huprine, and ethopropazine. We compare these structures to equivalent AChE complexes when available in the protein data bank and supplement this comparison with kinetic data and observations from isothermal titration calorimetry. This new information now allows us to define the binding mode of various ligand families and will be of importance in designing specific reversible ligands of BChE that behave as inhibitors or reactivators. PMID- 29186058 TI - A Real-Time Robust Method to Detect BeiDou GEO/IGSO Orbital Maneuvers. AB - The frequent maneuvering of BeiDou Geostationary Orbit (GEO) and Inclined Geosynchronous Orbit (IGSO) satellites affects the availability of real-time orbit, and decreases the accuracy and performance of positioning, navigation and time (PNT) services. BeiDou satellite maneuver information cannot be obtained by common users. BeiDou broadcast ephemeris is the only indicator of the health status of satellites, which are broadcast on an hourly basis, easily leading to ineffective observations. Sometimes, identification errors of satellite abnormity also appear in the broadcast ephemeris. This study presents a real-time robust detection method for a satellite orbital maneuver with high frequency and high reliability. By using the broadcast ephemeris and pseudo-range observations, the time discrimination factor and the satellite identification factor were defined and used for the real-time detection of start time and the pseudo-random noise code (PRN) of satellites was used for orbital maneuvers. Data from a Multi-GNSS Experiment (MGEX) was collected and analyzed. The results show that the start time and the PRN of the satellite orbital maneuver could be detected accurately in real time. In addition, abnormal start times and satellite abnormities caused by non-maneuver factors also could be detected using the proposed method. The new method not only improves the utilization of observations for users with the data effective for about 92 min, but also promotes the reliability of real-time PNT services. PMID- 29186059 TI - Effect of Gamma-Oryzanol as Therapeutic Agent to Prevent Cardiorenal Metabolic Syndrome in Animals Submitted to High Sugar-Fat Diet. AB - BACKGROUND: The high consumption of fat and sugar contributes to the development of obesity and co-morbidities, such as diabetes, and cardiovascular and kidney diseases. Different strategies have been used to prevent these diseases associated with obesity, such as changes in eating habits and/or the addition of dietary components with anti-inflammatory and anti-oxidant properties, such as gamma-oryzanol (gammaOz) present mainly in bran layers and rice germ. METHODS: Animals were randomly divided into four experimental groups and fed ad libitum for 20 weeks with control diet (C, n = 8), control diet + gammaOz (C + gammaOz, n = 8), high-sugar and high-fat diet (HSF, n = 8), and high-sugar and high-fat diet + gammaOz (HSF + gammaOz, n = 8). HSF groups also received water + sucrose (25%). The dose of gammaOz was added to diets to reach 0.5% of final concentration (w/w). Evaluation in animals included food and caloric intake, body weight, plasma glucose, insulin, triglycerides, uric acid, HOMA-IR, glomerular filtration rate, protein/creatinine ratio, systolic blood pressure, and Doppler echocardiographic. RESULTS: Animals that consumed the HSF diet had weight gain compared to group C, increased insulin, HOMA, glucose and triglycerides, there were also atrial and ventricular structural alterations, deterioration of systolic and diastolic function, decreased glomerular filtration rate, and proteinuria. Gamma-oryzanol is significantly protective against effects on body weight, hypertriglyceridemia, renal damage, and against structural and functional alteration of the heart. CONCLUSION: Gamma-oryzanol shows potential as a therapeutic to prevent Cardiorenal Metabolic Syndrome. PMID- 29186060 TI - Depth-Based Detection of Standing-Pigs in Moving Noise Environments. AB - In a surveillance camera environment, the detection of standing-pigs in real-time is an important issue towards the final goal of 24-h tracking of individual pigs. In this study, we focus on depth-based detection of standing-pigs with "moving noises", which appear every night in a commercial pig farm, but have not been reported yet. We first apply a spatiotemporal interpolation technique to remove the moving noises occurring in the depth images. Then, we detect the standing pigs by utilizing the undefined depth values around them. Our experimental results show that this method is effective for detecting standing-pigs at night, in terms of both cost-effectiveness (using a low-cost Kinect depth sensor) and accuracy (i.e., 94.47%), even with severe moving noises occluding up to half of an input depth image. Furthermore, without any time-consuming technique, the proposed method can be executed in real-time. PMID- 29186061 TI - Identification of Alpha and Beta Coronavirus in Wildlife Species in France: Bats, Rodents, Rabbits, and Hedgehogs. AB - Coronaviruses are closely monitored in the context of emerging diseases and, as illustrated with Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) and Middle East Respiratory Syndrome-coronavirus (MERS-CoV), are known to cross the species barrier and eventually to move from wildlife to humans. Knowledge of the diversity of coronaviruses in wildlife is therefore essential to better understand and prevent emergence events. This study explored the presence of coronaviruses in four wild mammal orders in France: Bats, rodents, lagomorphs, and hedgehogs. Betacoronavirus and Alphacoronavirus genera were identified. The results obtained suggest the circulation of potentially evolving virus strains, with the potential to cross the species barrier. PMID- 29186063 TI - Structural Masquerade of Plesiomonas shigelloides Strain CNCTC 78/89 O-Antigen High-Resolution Magic Angle Spinning NMR Reveals the Modified d-galactan I of Klebsiella pneumoniae. AB - The high-resolution magic angle spinning nuclear magnetic resonance spectroscopy (HR-MAS NMR) analysis of Plesiomonas shigelloides 78/89 lipopolysaccharide directly on bacteria revealed the characteristic structural features of the O acetylated polysaccharide in the NMR spectra. The O-antigen profiles were unique, yet the pattern of signals in the, spectra along with their 1H,13C chemical shift values, resembled these of d-galactan I of Klebsiella pneumoniae. The isolated O specific polysaccharide (O-PS) of P. shigelloides strain CNCTC 78/89 was investigated by 1H and 13C NMR spectroscopy, mass spectrometry and chemical methods. The analyses demonstrated that the P. shigelloides 78/89 O-PS is composed of ->3)-alpha-d-Galp-(1->3)-beta-d-Galf2OAc-(1-> disaccharide repeating units. The O-acetylation was incomplete and resulted in a microheterogeneity of the O-antigen. This O-acetylation generates additional antigenic determinants within the O-antigen, forms a new chemotype, and contributes to the epitopes recognized by the O-serotype specific antibodies. The serological cross reactivities further confirmed the inter-specific structural similarity of these O-antigens. PMID- 29186065 TI - Binge Alcohol Exposure Transiently Changes the Endocannabinoid System: A Potential Target to Prevent Alcohol-Induced Neurodegeneration. AB - Excessive alcohol consumption leads to neurodegeneration, which contributes to cognitive decline that is associated with alcohol use disorders (AUDs). The endocannabinoid system has been implicated in the development of AUDs, but little is known about how the neurotoxic effects of alcohol impact the endocannabinoid system. Therefore, the current study investigated the effects of neurotoxic, binge-like alcohol exposure on components of the endocannabinoid system and related N-acylethanolamines (NAEs), and then evaluated the efficacy of fatty acid amide hydrolase (FAAH) inhibition on attenuating alcohol-induced neurodegeneration. Male rats were administered alcohol according to a binge model, which resulted in a transient decrease in [3H]-CP-55,940 binding in the entorhinal cortex and hippocampus following two days, but not four days, of treatment. Furthermore, binge alcohol treatment did not change the tissue content of the three NAEs quantified, including the endocannabinoid and anandamide. In a separate study, the FAAH inhibitor, URB597 was administered to rats during alcohol treatment and neuroprotection was assessed by FluoroJade B (FJB) staining. The administration of URB597 during binge treatment did not significantly reduce FJB+ cells in the entorhinal cortex or hippocampus, however, a follow up "target engagement" study found that NAE augmentation by URB597 was impaired in alcohol intoxicated rats. Thus, potential alcohol induced alterations in URB597 pharmacodynamics may have contributed to the lack of neuroprotection by FAAH inhibition. PMID- 29186064 TI - Airway Mucus and Asthma: The Role of MUC5AC and MUC5B. AB - Asthma is characterized by mucus abnormalities. Airway epithelial hyperplasia and metaplasia result in changes in stored and secreted mucin and the production of a pathologic mucus gel. Mucus transport is impaired, culminating in mucus plugging and airway obstruction-a major cause of morbidity in asthma. The polymeric mucins MUC5AC and MUC5B are integral components of airway mucus. MUC5AC and MUC5B gene expression is altered in asthma, and recent work sheds light on their contribution to asthma pathogenesis. Herein, we review our current understanding of the role of MUC5AC and MUC5B in mucus dysfunction in asthma. PMID- 29186066 TI - An Advanced Hybrid Technique of DCS and JSRC for Telemonitoring of Multi-Sensor Gait Pattern. AB - The jointly quantitative analysis of multi-sensor gait data for the best gait classification performance has been a challenging endeavor in wireless body area networks (WBANs)-based gait telemonitoring applications. In this study, based on the joint sparsity of data, we proposed an advanced hybrid technique of distributed compressed sensing (DCS) and joint sparse representation classification (JSRC) for multi-sensor gait classification. Firstly, the DCS technique is utilized to simultaneously compress multi-sensor gait data for capturing spatio-temporal correlation information about gait while the energy efficiency of the sensors is available. Then, the jointly compressed gait data are directly used to develop a novel neighboring sample-based JSRC model by defining the sparse representation coefficients-inducing criterion (SRCC), in order to yield the best classification performance as well as a lower computational time cost. The multi-sensor gait data were selected from an open wearable action recognition database (WARD) to validate the feasibility of our proposed method. The results showed that when the comparison ratio and the number of neighboring samples are selected as 70% and 40%, respectively, the best accuracy (95%) can be reached while the lowest computational time spends only 60 ms. Moreover, the best accuracy and the computational time can increase by 5% and decrease by 40 ms, respectively, when compared with the traditional JSRC techniques. Our proposed hybrid technique can take advantage of the joint sparsity of data for jointly processing multi-sensor gait data, which greatly contributes to the best gait-classification performance. This has great potential for energy-efficient telemonitoring of multi-sensor gait. PMID- 29186067 TI - Immunohistochemical Characterization of Connexin43 Expression in a Mouse Model of Diabetic Retinopathy and in Human Donor Retinas. AB - Diabetic retinopathy (DR) develops due to hyperglycemia and inflammation-induced vascular disruptions in the retina with connexin43 expression patterns in the disease still debated. Here, the effects of hyperglycemia and inflammation on connexin43 expression in vitro in a mouse model of DR and in human donor tissues were evaluated. Primary human retinal microvascular endothelial cells (hRMECs) were exposed to high glucose (HG; 25 mM) or pro-inflammatory cytokines IL-1beta and TNF-alpha (10 ng/mL each) or both before assessing connexin43 expression. Additionally, connexin43, glial fibrillary acidic protein (GFAP), and plasmalemma vesicular associated protein (PLVAP) were labeled in wild-type (C57BL/6), Akita (diabetic), and Akimba (DR) mouse retinas. Finally, connexin43 and GFAP expression in donor retinas with confirmed DR was compared to age-matched controls. Co-application of HG and cytokines increased connexin43 expression in hRMECs in line with results seen in mice, with no significant difference in connexin43 or GFAP expression in Akita but higher expression in Akimba compared to wild-type mice. On PLVAP-positive vessels, connexin43 was higher in Akimba but unchanged in Akita compared to wild-type mice. Connexin43 expression appeared higher in donor retinas with confirmed DR compared to age-matched controls, similar to the distribution seen in Akimba mice and correlating with the in vitro results. Although connexin43 expression seems reduced in diabetes, hyperglycemia and inflammation present in the pathology of DR seem to increase connexin43 expression, suggesting a causal role of connexin43 channels in the disease progression. PMID- 29186068 TI - Study of Structure and Permeability Relationship of Flavonoids in Caco-2 Cells. AB - Flavonoids exhibit a broad range of biological activities. However, poor absorption of some flavonoids is a major limitation for use of flavonoids as nutraceuticals. To investigate the structure requirements for flavonoids intestinal absorption, transepithelial transport and cellular accumulation (CA) of 30 flavonoids were determined using the Caco-2 cell monolayer. The bilateral permeation of five types of flavonoids followed the order: flavanones >= isoflavones > flavones >= chalcones > flavonols. The concentration of flavonoids accumulated in cells did not correlate with cell penetration since the correlation coefficient between the apparent permeability coefficient (Papp) and their corresponding CA was poor (R2 < 0.3). Most flavonoids exhibited a ratio of 0.8-1.5 for Papp A to B/Papp B to A, suggesting passive diffusion pathways. However, luteolin, morin and taxifolin may involve the efflux mechanisms. The quantitative structure-permeability relationship (QSPR) study demonstrated that the intestinal absorption of flavonoids can be related to atomic charges on carbon 3' (QC3'), molecule surface area (SlogP_V3), balance between the center of mass and position of hydrophobic region (vsurf_ID1) and solvation energy of flavonoids (E_sol). These results provide useful information for initially screening of flavonoids with high intestinal absorption. PMID- 29186070 TI - Psychology of the Embrace: How Body Rhythms Communicate the Need to Indulge or Separate. AB - In the context of embodiment research, there has been a growing interest in phenomena of interpersonal resonance. Given that haptic communication is particularly under-researched, we focused on the phenomenon of embracing. When we embrace a dear friend to say good-bye at the end of a great evening, we typically first employ smooth and yielding movements with round transitions between muscular tensing and relaxing (smooth, indulging rhythms), and when the embrace is getting too long, we start to use slight patting (sharp, fighting rhythms with sharp transitions) on the back or the shoulders of the partner in order to indicate that we now want to end the embrace. On the ground of interpersonal resonance, most persons (per-sonare, latin = to sound through) understand these implicit nonverbal signals, expressed in haptic tension-flow changes, and will react accordingly. To experimentally test the hypothesis that smooth, indulgent rhythms signal the wish to continue, and sharp, fighting rhythms signal the wish to separate from an embrace, we randomly assigned 64 participants, all students at the University of Heidelberg, to two differently sequenced embrace conditions: (a) with the fighting rhythm at the end of the sequence of two indulgent rhythms (Sequence A: smooth-smooth-sharp); and (b) with the fighting rhythm between two indulgent rhythms (Sequence B: smooth-sharp-smooth). Participants were embraced for 30 s by a female confe-derate with their eyes blindfolded to focus on haptic and kinesthetic cues without being distracted by visual cues. They were instructed to let go of a handkerchief that they held between the fingers of their dominant hand during the embrace, when they felt that the embracer signaled the wish to finish the embrace. Participants significantly more often dropped the handkerchief in the phase of the fighting rhythm, no matter in which location it occurred in the embrace sequence. We assume that we learn such rhythmic behaviors and their meaning from the beginning of life in the communication with caregivers and meaningful others. Some are universal and some are quite idiosyncratic. Infants seem to be highly sensitive to the dynamic nuances presented to them, demonstrating a high capacity for embodied resonance and a high behavioral plasticity. Such adaptive mechanisms are assumed to lay the foundations of family culture (including the degree to which nonverbal cues are attended to, the communication of taboos, etc.) and larger culture, and may also play an important role in interpersonal attraction and aesthetic experience. PMID- 29186062 TI - Viral Oncology: Molecular Biology and Pathogenesis. AB - Oncoviruses are implicated in approximately 12% of all human cancers. A large number of the world's population harbors at least one of these oncoviruses, but only a small proportion of these individuals go on to develop cancer. The interplay between host and viral factors is a complex process that works together to create a microenvironment conducive to oncogenesis. In this review, the molecular biology and oncogenic pathways of established human oncoviruses will be discussed. Currently, there are seven recognized human oncoviruses, which include Epstein-Barr Virus (EBV), Human Papillomavirus (HPV), Hepatitis B and C viruses (HBV and HCV), Human T-cell lymphotropic virus-1 (HTLV-1), Human Herpesvirus-8 (HHV-8), and Merkel Cell Polyomavirus (MCPyV). Available and emerging therapies for these oncoviruses will be mentioned.

AB - Background: Mining activities always emit metal(loid)s into the surrounding environment, where their accumulation in the soil may pose risks and hazards to humans and ecosystems. Objective: This paper aims to determine of the type, source, chemical form, fate and transport, and accurate risk assessment of 17 metal(loid) contaminants including As, Cd, Cu, Ni, Pb, Zn, Cr, Ag, B, Bi, Co, Mo, Sb, Ti, V, W and Sn in the soils collected from an abandoned tungsten mining area, and to guide the implementing of appropriate remediation strategies. Methods: Contamination factors (CFs) and integrated pollution indexes (IPIs) and enrichment factors (EFs) were used to assess their ecological risk and the sources were identified by using multivariate statistics analysis, spatial distribution investigation and correlation matrix. Results: The IPI and EF values indicated the soils in the mine site and the closest downstream one were extremely disturbed by metal(loid)s such as As, Bi, W, B, Cu, Pb and Sn, which were emitted from the mining wastes and acid drainages and delivered by the runoff and human activities. Arsenic contamination was detected in nine sites with the highest CF values at 24.70 next to the mining site. The Cd contamination scattered in the paddy soils around the resident areas with higher fraction of bioavailable forms, primarily associated with intense application of phosphorus fertilizer. The lithogenic elements V, Ti, Ag, Ni, Sb, Mo exhibit low contamination in all sampling points and their distribution were depended on the soil texture and pedogenesis process. Conclusions: The long term historical mining activities have caused severe As contamination and higher enrichment of the other elements of orebody in the local soils. The appropriate remediation treatment approach should be proposed to reduce the bioavailability of Cd in the paddy soils and to immobilize As to reclaim the soils around the mining site. Furthermore, alternative fertilizing way and irrigating water sources are urgencies to reduce the input of Cd and As into the local soils effectively.

AB - Polo-like kinase 1 (PLK1) plays major roles in cell cycle control and DNA damage response. Therefore, PLK1 has been investigated as a target for cancer therapy. Volasertib is the second-in class dihydropteridinone derivate that is a specific PLK1 inhibitor. In this study, we examined that combining PLK1 inhibitor with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) would have an additive and synergistic effect on induction of apoptosis in cancer cells. We found that volasertib alone and TRAIL alone had no effect on apoptosis, but the combined treatment of volasertib and TRAIL markedly induced apoptosis in Caki (renal carcinoma), A498 (renal carcinoma) and A549 (lung carcinoma) cells, but not in normal cells (human skin fibroblast cells and mesangial cells). Combined treatment induced accumulation of sub-G1 phase, DNA fragmentation, cleavage of poly (ADP-ribose) polymerase (PARP) and activation of caspase 3 activity in Caki cells. Interestingly, combined treatment induced downregulation of cellular-FLICE inhibitory protein (c-FLIP) expression and ectopic expression of c-FLIP markedly blocked combined treatment-induced apoptosis. Therefore, this study demonstrates that volasertib may sensitize TRAIL-induced apoptosis in Caki cells via downregulation of c-FLIP. PMID- 29186072 TI - A Dependable Localization Algorithm for Survivable Belt-Type Sensor Networks. AB - As the key element, sensor networks are widely investigated by the Internet of Things (IoT) community. When massive numbers of devices are well connected, malicious attackers may deliberately propagate fake position information to confuse the ordinary users and lower the network survivability in belt-type situation. However, most existing positioning solutions only focus on the algorithm accuracy and do not consider any security aspects. In this paper, we propose a comprehensive scheme for node localization protection, which aims to improve the energy-efficient, reliability and accuracy. To handle the unbalanced resource consumption, a node deployment mechanism is presented to satisfy the energy balancing strategy in resource-constrained scenarios. According to cooperation localization theory and network connection property, the parameter estimation model is established. To achieve reliable estimations and eliminate large errors, an improved localization algorithm is created based on modified average hop distances. In order to further improve the algorithms, the node positioning accuracy is enhanced by using the steepest descent method. The experimental simulations illustrate the performance of new scheme can meet the previous targets. The results also demonstrate that it improves the belt-type sensor networks' survivability, in terms of anti-interference, network energy saving, etc. PMID- 29186073 TI - Evaluation of Inulin Replacing Chitosan in a Polyurethane/Polysaccharide Material for Pb2+ Removal. AB - Downstream waste from industry and other industrial processes could increase concentration of heavy metals in water. These pollutants are commonly removed by adsorption because it is an effective and economical method. Previously, we reported adsorption capacity of a chitosan/polyurethane/titanium dioxide (TiO2) composite for three ions in a dynamic wastewater system. There, increasing the chitosan concentration in composite increased the cation removal as well; however, for ratios higher than 50% of chitosan/TiO2, the manufacturing cost increased significantly. In this work, we address the manufacturing cost problem by proposing a new formulation of the composite. Our hypothesis is that inulin could replace chitosan in the composite formulation, either wholly or in part. In this exploratory research, three blends were prepared with a polyurethane matrix using inulin or/and chitosan. Adsorption was evaluated using a colorimetric method and the Langmuir and Freundlich models. Fourier-transform infrared spectroscopy (FTIR) spectra, scanning electron microscopy (SEM) micrographs, differential scanning calorimetry and thermogravimetric analysis curves were obtained to characterize blends. Results indicate that blends are suitable for toxic materials removal (specifically lead II, Pb2+). Material characterization indicates that polysaccharides were distributed in polyurethane's external part, thus improving adsorption. Thermal degradation of materials was found above 200 degrees C. Comparing the blends data, inulin could replace chitosan in part and thereby improve the cost efficiency and scalability of the production process of the polyurethane based-adsorbent. Further research with different inulin/chitosan ratios in the adsorbent and experiments with a dynamic system are justified. PMID- 29186075 TI - An Adaptive S-Method to Analyze Micro-Doppler Signals for Human Activity Classification. AB - In this paper, we propose the multiwindow Adaptive S-method (AS-method) distribution approach used in the time-frequency analysis for radar signals. Based on the results of orthogonal Hermite functions that have good time frequency resolution, we vary the length of window to suppress the oscillating component caused by cross-terms. This method can bring a better compromise in the auto-terms concentration and cross-terms suppressing, which contributes to the multi-component signal separation. Finally, the effective micro signal is extracted by threshold segmentation and envelope extraction. To verify the proposed method, six states of motion are separated by a classifier of a support vector machine (SVM) trained to the extracted features. The trained SVM can detect a human subject with an accuracy of 95.4% for two cases without interference. PMID- 29186074 TI - The Eukaryotic Elongation Factor 1 Alpha (eEF1alpha) from the Parasite Leishmania infantum Is Modified with the Immunomodulatory Substituent Phosphorylcholine (PC). AB - Proteins and glycolipids have been found to be decorated with phosphorylcholine (PC) both in protozoa and nematodes that parasitize humans and animals. PC epitopes can provoke various effects on immune cells leading to an immunomodulation of the host's immune system that allows long-term persistence of the parasites. So far, only a limited number of PC-modified proteins, mainly from nematodes, have been identified. Infections caused by Leishmania spp. (e.g., L. infantum in southern Europe) affect about 12 million people worldwide and are characterized by a wide spectrum of clinical forms in humans, ranging from cutaneous to fatal visceral leishmaniasis. To establish and maintain the infection, these protozoa are dependent on the secretion of effector molecules into the host for modulating their immune system. In this project, we analyzed the PC modification of L. infantum promastigotes by 2D-gel based proteomics. Western blot analysis with the PC-specific antibody TEPC-15 revealed one PC substituted protein in this organism, identified as eEF1alpha. We could demonstrate that the binding of eEF1alpha to one of its downstream effectors is dependent on its PC-modification. In this study we provide evidence that in this parasite the modification of eEF1alpha with PC may be essential for its function as an important virulence factor. PMID- 29186076 TI - The Role of Anti-Thymocyte Globulin or Alemtuzumab-Based Serotherapy in the Prophylaxis and Management of Graft-Versus-Host Disease. AB - Allogeneic hematopoietic stem cell transplant is an established treatment modality for hematologic and non-hematologic diseases. However, it is associated with acute and long-term sequelae which can translate into mortality. Graft versus-host disease (GVHD) remains a glaring obstacle, especially with the advent of reduced-intensity conditioning. Serotherapy capitalizes on antibodies which target T cells and other immune cells to mitigate this effect. This article focuses on the utility of two such agents: anti-thymocyte globulin (ATG) and alemtuzumab. ATG has demonstrated benefit in prophylaxis against GVHD, especially in the chronic presentation. However, there is limited impact of ATG on overall survival and it has little utility in the treatment context. There may be an initial improvement, particularly in skin manifestations, but no substantial benefit has been elicited. Alemtuzumab has shown benefit in both prophylaxis and treatment of GVHD, but at the consequence of a more profound immunosuppressive phase, mandating aggressive viral prophylaxis. There remains heterogeneity in the doses and regimens of the agents, with no standardized protocol in place. Furthermore, it seems that once steroid-refractory GVHD has been established, there is little that can be offered to offset the ultimately dismal outcome. Here we present a systematic overview of ATG- or alemtuzumab-based serotherapy in the prophylaxis and management of GVHD. PMID- 29186078 TI - Biological Properties of Low-Toxicity PLGA and PLGA/PHB Fibrous Nanocomposite Implants for Osseous Tissue Regeneration. Part I: Evaluation of Potential Biotoxicity. AB - In response to the demand for new implant materials characterized by high biocompatibility and bioresorption, two prototypes of fibrous nanocomposite implants for osseous tissue regeneration made of a newly developed blend of poly(l-lactide-co-glycolide) (PLGA) and syntheticpoly([R,S]-3-hydroxybutyrate), PLGA/PHB, have been developed and fabricated. Afibre-forming copolymer of glycolide and l-lactide (PLGA) was obtained by a unique method of synthesis carried out in blocksusing Zr(AcAc)4 as an initiator. The prototypes of the implants are composed of three layers of PLGA or PLGA/PHB, nonwoven fabrics with a pore structure designed to provide the best conditions for the cell proliferation. The bioactivity of the proposed implants has been imparted by introducing a hydroxyapatite material and IGF1, a growth factor. The developed prototypes of implants have been subjected to a set of in vitro and in vivobiocompatibility tests: in vitro cytotoxic effect, in vitro genotoxicity and systemic toxicity. Rabbitsshowed no signs of negative reactionafter implantation of the experimental implant prototypes. PMID- 29186079 TI - Assessment of Embedded Conjugated Polymer Sensor Arrays for Potential Load Transmission Measurement in Orthopaedic Implants. AB - Load transfer through orthopaedic joint implants is poorly understood. The longer term outcomes of these implants are just starting to be studied, making it imperative to monitor contact loads across the entire joint implant interface to elucidate the force transmission and distribution mechanisms exhibited by these implants in service. This study proposes and demonstrates the design, implementation, and characterization of a 3D-printed smart polymer sensor array using conductive polyaniline (PANI) structures embedded within a polymeric parent phase. The piezoresistive characteristics of PANI were investigated to characterize the sensing behaviour inherent to these embedded pressure sensor arrays, including the experimental determination of the stable response of PANI to continuous loading, stability throughout the course of loading and unloading cycles, and finally sensor repeatability and linearity in response to incremental loading cycles. This specially developed multi-material additive manufacturing process for PANI is shown be an attractive approach for the fabrication of implant components having embedded smart-polymer sensors, which could ultimately be employed for the measurement and analysis of joint loads in orthopaedic implants for in vitro testing. PMID- 29186080 TI - E2mC: Improving Emergency Management Service Practice through Social Media and Crowdsourcing Analysis in Near Real Time. AB - In the first hours of a disaster, up-to-date information about the area of interest is crucial for effective disaster management. However, due to the delay induced by collecting and analysing satellite imagery, disaster management systems like the Copernicus Emergency Management Service (EMS) are currently not able to provide information products until up to 48-72 h after a disaster event has occurred. While satellite imagery is still a valuable source for disaster management, information products can be improved through complementing them with user-generated data like social media posts or crowdsourced data. The advantage of these new kinds of data is that they are continuously produced in a timely fashion because users actively participate throughout an event and share related information. The research project Evolution of Emergency Copernicus services (E2mC) aims to integrate these novel data into a new EMS service component called Witness, which is presented in this paper. Like this, the timeliness and accuracy of geospatial information products provided to civil protection authorities can be improved through leveraging user-generated data. This paper sketches the developed system architecture, describes applicable scenarios and presents several preliminary case studies, providing evidence that the scientific and operational goals have been achieved. PMID- 29186081 TI - Properties-Adjustable Alumina-Zirconia Nanolaminate Dielectric Fabricated by Spin Coating. AB - In this paper, an alumina-zirconia (Al2O3-ZrO2) nanolaminate dielectric was fabricated by spin-coating and the performance was investigated. It was found that the properties of the dielectric can be adjusted by changing the content of Al2O3/ZrO2 in nanolaminates: when the content of Al2O3 was higher than 50%, the properties of nanolaminates, such as the optical energy gap, dielectric strength (Vds), capacitance density, and relative permittivity were relatively stable, while the change of these properties became larger when the content of Al2O3 was less than 50%. With the content of ZrO2 varying from 50% to 100%, the variation of these properties was up to 0.482 eV, 2.12 MV/cm, 135.35 nF/cm2, and 11.64, respectively. Furthermore, it was demonstrated that the dielectric strength of nanolaminates were influenced significantly by the number (n) of bilayers. Every increment of one Al2O3-ZrO2 bilayer will enhance the dielectric strength by around 0.39 MV/cm (Vds ~ 0.86 + 0.39n). This could be contributed to the amorphous alumina which interrupted the grain boundaries of zirconia. PMID- 29186082 TI - Shingrix--an adjuvanted, recombinant herpes zoster vaccine.

AB - Telomeres are repetitive tandem DNA sequences that cap chromosomal ends protecting genomic DNA from enzymatic degradation. Telomeres progressively shorten with cellular replication and are therefore assumed to correlate with biological and chronological age. An expanding body of evidence suggests (i) a predictable inverse association between telomere length, aging and age-related diseases and (ii) a positive association between physical activity and telomere length. Both hypotheses have garnered tremendous research attention and broad consensus; however, the evidence for each proposition is inconsistent and equivocal at best. Telomere length does not meet the basic criteria for an aging biomarker and at least 50% of key studies fail to find associations with physical activity. In this review, we address the evidence in support and refutation of the putative associations between telomere length, aging and physical activity. We finish with a brief review of plausible mechanisms and potential future research directions. PMID- 29186087 TI - Three more immune checkpoint inhibitors for advanced bladder cancer.

PMID- 29186089 TI - Correlation Between Methylenetetrahydrofolate Reductase (MTHFR) C677T Polymorphisms and Pemetrexed Chemotherapy Efficacy/Toxicity in Non-Squamous Non Small Cell Lung Cancer. AB - BACKGROUND In the present study, we aimed to retrospectively analyze the correlation between toxicity of pemetrexed (PEM) chemotherapy and methylenetetrahydrofolate reductase (MTHFR) C677T polymorphisms in patients with advanced non-squamous non-small cell lung cancer (non-sq NSCLC). MATERIAL AND METHODS We used polymerase chain reaction, gene scanning, and restriction fragment length polymorphism to analyze MTHFR C677T in 51 patients with advanced non-sq NSCLC. The patients received chemotherapies with single-agent PEM (monotherapy group) or with PEM combined with cisplatin (joint group). The correlation between MTHFR C677T polymorphisms and chemotherapy efficacy/toxicity was also assessed. RESULTS There were 40 patients in the monotherapy group and 11 patients in the joint group. Among the 40 patients received single-agent PEM chemotherapy, those with the CT/TT genotype had higher incidence of leukopenia, neutropenia, nausea, and fatigue compared to patients with the with wild-type genotype CC (all P<0.05). However, polymorphisms of MTHFR C677T were not significantly associated with other adverse events and clinical outcomes. CONCLUSIONS Compared with genotype CC (the wild type), patients with the CT/TT genotype had higher incidence of leukopenia, neutropenia, nausea, and fatigue. Therefore, the MTHFR C677T polymorphism could be a predictive factor for leukopenia, neutropenia, nausea, and fatigue toxicities in non-sq NSCLC patients treated with single-agent PEM. PMID- 29186090 TI - [Comparative analysis of the effectiveness of various techniques of endoscopic prostate enucleation in a single center]. AB - AIM: To compare electro- and laser enucleation (thulium, holmium) of prostate hyperplasia. MATERIAL AND METHODS: 693 prostate hyperplasia patients were enrolled. 489 patients underwent holmium enucleation (HoLEP), 51 - monopolar enucleation, 153 - thulium enucleation (ThuLEP). Prostate volume was 91.7 (50 250) cm3. There were no significant differences in preoperative variables between both groups (I-PSS, QoL, Qmax, residual urine volume) (p>0.05). RESULTS: Mean time of HoLEP was 97.0+/-42.2 min, monopolar enucleation - 112.9+/-36.3 min, ThuLEP duration was significantly less (77.4+/-36.3 min, p<0.01). An efficacy of all methods was confirmed in 6 months after surgery by significant (p<0.01) improvement of functional parameters (I-PSS, QoL, Qmax, residual urine volume). CONCLUSION: High efficiency of thulium and holmium enucleation allows to consider them as 'gold standard' of prostate hyperplasia management. Despite higher incidence of complications an efficacy of monopolar enucleation is comparable to that in laser techniques. PMID- 29186091 TI - [Managerial and methodological aspects of emergency surgery for malignant colonic obstruction]. AB - AIM: To determine the most feasible treatment strategy for malignant colonic obstruction. MATERIAL AND METHODS: There were 427 patients with malignant colonic obstruction who were hospitalized for emergency indications. 30 of them were treated with medical therapy; 286 - underwent acute resection; 43 - stoma construction; 68 - stents deployment. 64 out of 427 patients underwent elective restorative/radical surgery and radio- or chemotherapy in 1-8 months. 3-year Kaplan-Meier survival was assessed. RESULTS: Complications occurred in 58% after acute resection and in 32.6% and 8.8% after stoma and stent deployment, respectively. Postoperative mortality was significantly lower after palliative surgery (stent or stoma) compared with acute resection: 2.9%, 18.6%, 29.37%, respectively. 3-year survival was higher after elective resections compared with emergency resection group: 0,81 i 0,68 respectively. CONCLUSION: Bridging strategy (stoma/stents) may be a valid alternative in some patients with malignant colonic obstruction due to significantly reduced postoperative mortality. Acute surgery for malignant colonic obstruction should only be carried out by appropriately trained surgeons at multi-field hospital. PMID- 29186093 TI - [Rehbein procedure for secondary megacolon in children]. AB - AIM: To evaluate the results of Rehbein procedure with extraperitoneal colorectal anastomosis combined with complex conservative treatment in children with secondary megacolon due to chronic constipation. MATERIAL AND METHODS: We carried out surgical interventions in 78 children aged 7-12 years with chronic colostasis resistant to conservative treatment. All patients underwent clinical, laboratory and instrumental examination. All patients were divided into 3 groups depending on type of surgery: group I - colon resection followed by intraperitoneal colorectal anastomosis (28 patients), group II - open Rehbein procedure (29 patients), group III - laparoscopic Rehbein procedure (21 patients). RESULTS: Absence of dyspeptic disorders and enterocolitis in remote postoperative period in patients receiving comprehensive treatment enhanced with new additions is the cause of improved outcomes. Type of surgery should be individualized in view of anatomical colon changes and secondary pathological conditions. Some pathological symptoms observed at preoperative period may be recurrent in long-term postoperative period due to wrong selection of surgery. The risk of recurrent chronic constipation is high after colon resection followed by intraperitoneal colorectal anastomosis. CONCLUSION: Rehbein procedure may be preferred for management of secondary megarectum and megasigma. Laparoscopic technique reduces surgical trauma and requires less postoperative analgesia. PMID- 29186092 TI - [Emergency endoscopic surgery of colon cancer]. AB - AIM: To assess the role of endoscopic technologies in treatment of complicated forms of colorectal cancer. MATERIAL AND METHODS: Our trial included patients after endoscopic intervention (n=18) and open surgery (n=11). RESULTS: Mean time of surgery in this group was 158.8+/-10.7 minutes. In elective surgery group this value was 161.3 minutes (p>0.05). Mean blood loss was not great (near 122.5+/ 17.9 ml). Overall and postoperative hospital-stay was 23.1+/-2.4 and 8.6+/-0.5 days, respectively. There were no intraoperative and postoperative complications. CONCLUSION: Endoscopic interventions may be performed for colon cancer for emergency indications including patients with severe complications. PMID- 29186094 TI - [Pectoral-retroauricular approach for endoscopic parathyroidectomy (experimental study)]. AB - AIM: To develop and investigate in the experiment the method of endoscopic parathyroidectomy in order to prevent intraoperative 'conflict of the instruments' and to reduce surgical trauma via extracervical approach. MATERIAL AND METHODS: The results of 10 experimental endoscopic parathyroidectomies with original pectoral-retroauricular approach were analyzed. RESULTS: Mean time of surgery was 77.8+/-10.2 minutes (65-97), mean time of surgical exposure - 50.3+/ 6.7 minutes (41-59). Visualization and identification of parathyroid glands were achieved in 100% of cases. Recurrent laryngeal nerve was preserved in 100% of cases. CONCLUSION: Original endoscopic pectoral-retroauricular approach for parathyroidectomy is methodologically and technically justified and can be recommended for clinical application. PMID- 29186095 TI - [Intraoperative fluid therapy during esophagectomy followed by repair]. AB - AIM: To optimize fluid therapy in transhiatal eshophagectomy by using of goal oriented infusion therapy based on stroke volume variation. MATERIAL AND METHODS: Our trial enrolled 30 patients who underwent transhiatal esophagectomy followed by repair for the period 2011-2014. Patients were divided into 2 groups. The first group (LT) included 16 patients with liberal fluid therapy. The second group (GDT) consisted of 14 patients in whom goal-oriented fluid therapy was performed. Goal-oriented fluid therapy was implemented via stroke volume variation (SVV). RESULTS: Infusion rate was 6.7 ml/kg/h and 11.5 ml/kg/h in the main and control groups, respectively. Morbidity rate was 28.6% (n=4) and 62.5% (n=10) in the main and control groups respectively. Clavien-Dindo IV complications were lung atelectasis (n=2, 14%), pneumonia (n=1, 7%). Hydrothorax required puncture was noted in 1 (7%) case. Acute respiratory failure as complication IVa was in 1 (9%) patient. In the control group complications were registered in 10 (62.5%) patients. Complications I-II degree included lung atelectasis (n=4, 25%), cervical anastomosis failure (n=1, 6%); complications IVa were observed in 8 cases (50%). It was significant respiratory failure with reduced PO2/FiO2<300. Patients of the main group required less time for postoperative mechanical ventilation (120 [90-300] vs. 315 [215-810] min (p=0.02) and ICU-stay (0.83 [0.7-0.8] vs. 1.75 [1.25-2.75] (p=0.0022).

AB - BackgroundTo characterize the influence of microbial invasion of the amniotic cavity (MIAC) and/or intra-amniotic inflammation (IAI) on the intensity of the fetal inflammatory response and the association between the presence of the fetal inflammatory response syndrome (FIRS) and short-term neonatal morbidity in the preterm prelabor rupture of membranes (PPROM) between the gestational ages of 34 and 37 weeks.MethodsOne hundred and fifty-nine women were included in the study. The umbilical cord blood interleukin (IL)-6 concentrations were determined using enzyme-linked immunosorbent assay kits. FIRS was defined based on the umbilical cord blood IL-6 concentration and the presence of funisitis and/or chorionic plate vasculitis.ResultsWomen with both MIAC and IAI had the highest median umbilical cord blood IL-6 concentrations and highest rates of FIRS. Women with FIRS had the higher rates of early-onset sepsis and intraventricular hemorrhage grades I and II when FIRS was characterized based on the umbilical cord blood IL 6 concentrations and the histopathological findings.ConclusionThe presence of both MIAC and IAI was associated with a higher fetal inflammatory response and a higher rate of FIRS. Different aspects of short-term neonatal morbidity were related to FIRS when defined by umbilical cord blood IL-6 concentrations and the histopathology of the placenta. PMID- 29186108 TI - IL-15 supports the generation of protective lung-resident memory CD4 T cells. AB - Tissue-resident memory T cells (TRM) provide optimal defense at the sites of infection, but signals regulating their development are unclear, especially for CD4 T cells. Here we identify two distinct pathways that lead to the generation of CD4 TRM in the lungs following influenza infection. The TRM are transcriptionally distinct from conventional memory CD4 T cells and share a gene signature with CD8 TRM. The CD4 TRM are superior cytokine producers compared with conventional memory cells, can protect otherwise naive mice against a lethal influenza challenge, and display functional specialization by inducing enhanced inflammatory responses from dendritic cells compared with conventional memory cells. Finally, we demonstrate than an interleukin (IL)-2-dependent and a novel IL-2-independent but IL-15-dependent pathway support the generation of cohorts of lung TRM. PMID- 29186107 TI - Mucocutaneous IL-17 immunity in mice and humans: host defense vs. excessive inflammation. AB - Interleukin (IL)-17A is a pro-inflammatory cytokine in mice and humans. It is recognized as a key factor for the protection of mice against various pathogens, but it also underlies pathogenic inflammatory responses in numerous mouse models. The inborn errors of IL-17A- and IL-17F-mediated immunity identified in humans in the last decade have revealed that IL-17A and IL-17F are key players in mucocutaneous immunity to Candida albicans, and, to a lesser extent, Staphylococcus aureus. By contrast, there is currently no genetic evidence for a causal link between excess of IL-17 and autoimmunity, autoinflammation, or allergy in humans. We discuss here the physiological and pathological roles of mouse and human IL-17A and IL-17F in host defense and excessive inflammation. We highlight recent advances in our understanding of the consequences of deficient or excessive IL-17 immunity at various mucocutaneous sites, including the oral cavity, skin, intestine, lungs, and vagina. PMID- 29186109 TI - Absence of specific alternatively spliced exon of CD44 in macrophages prevents colitis. AB - CD44 is a transmembrane molecule appearing in numerous isoforms generated by insertions of alternatively spliced variant exons (CD44v) and having various binding partners. CD44v7 on T cells was proposed to promote colitis by preventing T-cell apoptosis. Here we demonstrate that Cd44v7-deficient T cells - like Cd44 wild-type (Cd44WT) T cells - provoked disease in two different colitis models: the model induced by CD4+CD45RBhigh T-cell transfer into Rag2-deficient mice and a new model based on ovalbumin (OVA)-specific T-cell transfer into Rag sufficient, OVA-challenged mice. In contrast, CD44v7 absence on macrophages in recipient mice prevented colitis. Prevention was associated with the downregulation of signal transducer and activator of transcription 3 (STAT3) activating and Foxp3-counteracting interleukin-6 (IL-6), lower numbers of phospho STAT3-containing lymphocytes, and higher Foxp3+ T-cell counts in the colon. Consequently, the protected colons showed lower IL-12, IL-1beta expression, and decreased interferon-gamma levels. Importantly, stimulation of T cells by Cd44v7 deficient macrophages induced upregulation of Foxp3 in vitro, while cotransfer of Cd44WT macrophages into Cd44v7-deficient mice reduced Foxp3+ T-cell counts and caused colitis. Accordingly, the CD44v7 ligand osteopontin, whose levels were elevated in Crohn's disease, specifically induced IL-6 in human monocytes, a cytokine also increased in these patients. We suggest macrophage-specific targeting of the CD44v7 pathway as a novel therapeutic option for Crohn's disease.

AB - High-energy cosmic-ray electrons and positrons (CREs), which lose energy quickly during their propagation, provide a probe of Galactic high-energy processes and may enable the observation of phenomena such as dark-matter particle annihilation or decay. The CRE spectrum has been measured directly up to approximately 2 teraelectronvolts in previous balloon- or space-borne experiments, and indirectly up to approximately 5 teraelectronvolts using ground-based Cherenkov gamma-ray telescope arrays. Evidence for a spectral break in the teraelectronvolt energy range has been provided by indirect measurements, although the results were qualified by sizeable systematic uncertainties. Here we report a direct measurement of CREs in the energy range 25 gigaelectronvolts to 4.6 teraelectronvolts by the Dark Matter Particle Explorer (DAMPE) with unprecedentedly high energy resolution and low background. The largest part of the spectrum can be well fitted by a 'smoothly broken power-law' model rather than a single power-law model. The direct detection of a spectral break at about 0.9 teraelectronvolts confirms the evidence found by previous indirect measurements, clarifies the behaviour of the CRE spectrum at energies above 1 teraelectronvolt and sheds light on the physical origin of the sub teraelectronvolt CREs.

RNA polymerase (Pol) III is the essential, evolutionarily conserved enzyme that generates short, non-coding RNAs, including tRNAs and 5S rRNA. The historical focus on transcription of protein-coding genes has left the roles of Pol III in organismal physiology relatively unexplored. Target of rapamycin kinase complex 1 (TORC1) regulates Pol III activity, and is also an important determinant of longevity. This raises the possibility that Pol III is involved in ageing. Here we show that Pol III limits lifespan downstream of TORC1. We find that a reduction in Pol III extends chronological lifespan in yeast and organismal lifespan in worms and flies. Inhibiting the activity of Pol III in the gut of adult worms or flies is sufficient to extend lifespan; in flies, longevity can be achieved by Pol III inhibition specifically in intestinal stem cells. The longevity phenotype is associated with amelioration of age related gut pathology and functional decline, dampened protein synthesis and increased tolerance of proteostatic stress. Pol III acts on lifespan downstream of TORC1, and limiting Pol III activity in the adult gut achieves the full longevity benefit of systemic TORC1 inhibition. Hence, Pol III is a pivotal mediator of this key nutrient-signalling network for longevity; the growth promoting anabolic activity of Pol III mediates the acceleration of ageing by TORC1. The evolutionary conservation of Pol III affirms its potential as a therapeutic target. PMID- 29186114 TI - Corrigendum: Groundwater depletion embedded in international food trade.

AB - The sustainability of malaria control in Africa is threatened by the rise of insecticide resistance in Anopheles mosquitoes, which transmit the disease. To gain a deeper understanding of how mosquito populations are evolving, here we sequenced the genomes of 765 specimens of Anopheles gambiae and Anopheles coluzzii sampled from 15 locations across Africa, and identified over 50 million single nucleotide polymorphisms within the accessible genome. These data revealed complex population structure and patterns of gene flow, with evidence of ancient expansions, recent bottlenecks, and local variation in effective population size. Strong signals of recent selection were observed in insecticide-resistance genes, with several sweeps spreading over large geographical distances and between species. The design of new tools for mosquito control using gene-drive systems will need to take account of high levels of genetic diversity in natural mosquito populations. PMID- 29186113 TI - Inactivation of DNA repair triggers neoantigen generation and impairs tumour growth. AB - Molecular alterations in genes involved in DNA mismatch repair (MMR) promote cancer initiation and foster tumour progression. Cancers deficient in MMR frequently show favourable prognosis and indolent progression. The functional basis of the clinical outcome of patients with tumours that are deficient in MMR is not clear. Here we genetically inactivate MutL homologue 1 (MLH1) in colorectal, breast and pancreatic mouse cancer cells. The growth of MMR-deficient cells was comparable to their proficient counterparts in vitro and on transplantation in immunocompromised mice. By contrast, MMR-deficient cancer cells grew poorly when transplanted in syngeneic mice. The inactivation of MMR increased the mutational burden and led to dynamic mutational profiles, which resulted in the persistent renewal of neoantigens in vitro and in vivo, whereas MMR-proficient cells exhibited stable mutational load and neoantigen profiles over time. Immune surveillance improved when cancer cells, in which MLH1 had been inactivated, accumulated neoantigens for several generations. When restricted to a clonal population, the dynamic generation of neoantigens driven by MMR further increased immune surveillance. Inactivation of MMR, driven by acquired resistance to the clinical agent temozolomide, increased mutational load, promoted continuous renewal of neoantigens in human colorectal cancers and triggered immune surveillance in mouse models. These results suggest that targeting DNA repair processes can increase the burden of neoantigens in tumour cells; this has the potential to be exploited in therapeutic approaches. PMID- 29186115 TI - A transfer-RNA-derived small RNA regulates ribosome biogenesis. AB - Transfer-RNA-derived small RNAs (tsRNAs; also called tRNA-derived fragments) are an abundant class of small non-coding RNAs whose biological roles are not well understood. Here we show that inhibition of a specific tsRNA, LeuCAG3'tsRNA, induces apoptosis in rapidly dividing cells in vitro and in a patient-derived orthotopic hepatocellular carcinoma model in mice. This tsRNA binds at least two ribosomal protein mRNAs (RPS28 and RPS15) to enhance their translation. A decrease in translation of RPS28 mRNA blocks pre-18S ribosomal RNA processing, resulting in a reduction in the number of 40S ribosomal subunits. These data establish a post-transcriptional mechanism that can fine-tune gene expression during different physiological states and provide a potential new target for treating cancer. PMID- 29186116 TI - Immune evasion of Plasmodium falciparum by RIFIN via inhibitory receptors. AB - Malaria is among the most serious infectious diseases affecting humans, accounting for approximately half a million deaths each year. Plasmodium falciparum causes most life-threatening cases of malaria. Acquired immunity to malaria is inefficient, even after repeated exposure to P. falciparum, but the immune regulatory mechanisms used by P. falciparum remain largely unknown. Here we show that P. falciparum uses immune inhibitory receptors to achieve immune evasion. RIFIN proteins are products of a polymorphic multigene family comprising approximately 150-200 genes per parasite genome that are expressed on the surface of infected erythrocytes. We found that a subset of RIFINs binds to either leucocyte immunoglobulin-like receptor B1 (LILRB1) or leucocyte-associated immunoglobulin-like receptor 1 (LAIR1). LILRB1-binding RIFINs inhibit activation of LILRB1-expressing B cells and natural killer (NK) cells. Furthermore, P. falciparum-infected erythrocytes isolated from patients with severe malaria were more likely to interact with LILRB1 than erythrocytes from patients with non severe malaria, although an extended study with larger sample sizes is required to confirm this finding. Our results suggest that P. falciparum has acquired multiple RIFINs to evade the host immune system by targeting immune inhibitory receptors.

PMID- 29186117 TI - Maternal age generates phenotypic variation in Caenorhabditis elegans. AB - Genetically identical individuals that grow in the same environment often show substantial phenotypic variation within populations of organisms as diverse as bacteria, nematodes, rodents and humans. With some exceptions, the causes are poorly understood. Here we show that isogenic Caenorhabditis elegans nematodes vary in their size at hatching, speed of development, growth rate, starvation resistance, fecundity, and also in the rate of development of their germline relative to that of somatic tissues. We show that the primary cause of this variation is the age of an individual's mother, with the progeny of young mothers exhibiting several phenotypic impairments. We identify age-dependent changes in the maternal provisioning of the lipoprotein complex vitellogenin to embryos as the molecular mechanism that underlies the variation in multiple traits throughout the life of an animal. The production of sub-optimal progeny by young mothers may reflect a trade-off between the competing fitness traits of a short generation time and the survival and fecundity of the progeny.

PMID- 29186119 TI - Genetically programmed chiral organoborane synthesis. AB - Recent advances in enzyme engineering and design have expanded nature's catalytic repertoire to functions that are new to biology. However, only a subset of these engineered enzymes can function in living systems. Finding enzymatic pathways that form chemical bonds that are not found in biology is particularly difficult in the cellular environment, as this depends on the discovery not only of new enzyme activities, but also of reagents that are both sufficiently reactive for the desired transformation and stable in vivo. Here we report the discovery, evolution and generalization of a fully genetically encoded platform for producing chiral organoboranes in bacteria. Escherichia coli cells harbouring wild-type cytochrome c from Rhodothermus marinus (Rma cyt c) were found to form carbon-boron bonds in the presence of borane-Lewis base complexes, through carbene insertion into boron-hydrogen bonds. Directed evolution of Rma cyt c in the bacterial catalyst provided access to 16 novel chiral organoboranes. The catalyst is suitable for gram-scale biosynthesis, providing up to 15,300 turnovers, a turnover frequency of 6,100 h-1, a 99:1 enantiomeric ratio and 100% chemoselectivity. The enantiopreference of the biocatalyst could also be tuned to provide either enantiomer of the organoborane products. Evolved in the context of whole-cell catalysts, the proteins were more active in the whole-cell system than in purified forms. This study establishes a DNA-encoded and readily engineered bacterial platform for borylation; engineering can be accomplished at a pace that rivals the development of chemical synthetic methods, with the ability to achieve turnovers that are two orders of magnitude (over 400-fold) greater than those of known chiral catalysts for the same class of transformation. This tunable method for manipulating boron in cells could expand the scope of boron chemistry in living systems. PMID- 29186120 TI - Pluripotent state transitions coordinate morphogenesis in mouse and human embryos. AB - The foundations of mammalian development lie in a cluster of embryonic epiblast stem cells. In response to extracellular matrix signalling, these cells undergo epithelialization and create an apical surface in contact with a cavity, a fundamental event for all subsequent development. Concomitantly, epiblast cells transit through distinct pluripotent states, before lineage commitment at gastrulation. These pluripotent states have been characterized at the molecular level, but their biological importance remains unclear. Here we show that exit from an unrestricted naive pluripotent state is required for epiblast epithelialization and generation of the pro-amniotic cavity in mouse embryos. Embryonic stem cells locked in the naive state are able to initiate polarization but fail to undergo lumenogenesis. Mechanistically, exit from naive pluripotency activates an Oct4-governed transcriptional program that results in expression of glycosylated sialomucin proteins and the vesicle tethering and fusion events of lumenogenesis. Similarly, exit of epiblasts from naive pluripotency in cultured human post-implantation embryos triggers amniotic cavity formation and developmental progression. Our results add tissue-level architecture as a new criterion for the characterization of different pluripotent states, and show the relevance of transitions between these states during development of the mammalian embryo.

PMID- 29186124 TI - Reconciling taxon senescence with the Red Queen's hypothesis. AB - In the fossil record, taxa exhibit a regular pattern of waxing and waning of occupancy, range or diversity between their origin and extinction. This pattern appears to contradict the law of constant extinction, which states that the probability of extinction in a given taxon is independent of that taxon's age. It is nevertheless well established for species, genera and higher taxa of terrestrial mammals, marine invertebrates, marine microorganisms, and recent Hawaiian clades of animals and plants. Here we show that the apparent contradiction between a stochastically constant extinction rate and the seemingly deterministic waxing and waning pattern of taxa disappears when we consider their peak of expansion rather than their final extinction. To a first approximation, we find that biotic drivers of evolution pertain mainly to the peak of taxon expansion, whereas abiotic drivers mainly apply to taxon extinction. The Red Queen's hypothesis, which emphasizes biotic interactions, was originally proposed as an explanation of the law of constant extinction. Much effort has since been devoted to determining how this hypothesis, emphasizing competition for resources, relates to the effects of environmental change. One proposed resolution is that biotic and abiotic processes operate at different scales. By focusing attention on taxon expansion rather than survival, we resolve an apparent contradiction between the seemingly deterministic waxing and waning patterns over time and the randomness of extinction that the Red Queen's hypothesis implies.

AB - N6-methyladenosine (m6A) is an abundant internal RNA modification in both coding and non-coding RNAs that is catalysed by the METTL3-METTL14 methyltransferase complex. However, the specific role of these enzymes in cancer is still largely unknown. Here we define a pathway that is specific for METTL3 and is implicated in the maintenance of a leukaemic state. We identify METTL3 as an essential gene for growth of acute myeloid leukaemia cells in two distinct genetic screens. Downregulation of METTL3 results in cell cycle arrest, differentiation of leukaemic cells and failure to establish leukaemia in immunodeficient mice. We show that METTL3, independently of METTL14, associates with chromatin and localizes to the transcriptional start sites of active genes. The vast majority of these genes have the CAATT-box binding protein CEBPZ present at the transcriptional start site, and this is required for recruitment of METTL3 to chromatin. Promoter-bound METTL3 induces m6A modification within the coding region of the associated mRNA transcript, and enhances its translation by relieving ribosome stalling. We show that genes regulated by METTL3 in this way are necessary for acute myeloid leukaemia. Together, these data define METTL3 as a regulator of a chromatin-based pathway that is necessary for maintenance of the leukaemic state and identify this enzyme as a potential therapeutic target for acute myeloid leukaemia.

AB - The CRISPR-Cas9 system enables global screens of gene function with high sensitivity and specificity, but off-target effects have been reported for CRISPR guide RNAs targeting genes that are amplified at high copy number.

PMID- 29186132 TI - Dynamical compensation and structural identifiability of biological models: Analysis, implications, and reconciliation. AB - The concept of dynamical compensation has been recently introduced to describe the ability of a biological system to keep its output dynamics unchanged in the face of varying parameters. However, the original definition of dynamical compensation amounts to lack of structural identifiability. This is relevant if model parameters need to be estimated, as is often the case in biological modelling. Care should we taken when using an unidentifiable model to extract biological insight: the estimated values of structurally unidentifiable parameters are meaningless, and model predictions about unmeasured state variables can be wrong. Taking this into account, we explore alternative definitions of dynamical compensation that do not necessarily imply structural unidentifiability. Accordingly, we show different ways in which a model can be made identifiable while exhibiting dynamical compensation. Our analyses enable the use of the new concept of dynamical compensation in the context of parameter identification, and reconcile it with the desirable property of structural identifiability. PMID- 29186131 TI - Low-dose proton radiation effects in a transgenic mouse model of Alzheimer's disease - Implications for space travel. AB - Space radiation represents a significant health risk for astronauts. Ground-based animal studies indicate that space radiation affects neuronal functions such as excitability, synaptic transmission, and plasticity, and it may accelerate the onset of Alzheimer's disease (AD). Although protons represent the main constituent in the space radiation spectrum, their effects on AD-related pathology have not been tested. We irradiated 3 month-old APP/PSEN1 transgenic (TG) and wild type (WT) mice with protons (150 MeV; 0.1-1.0 Gy; whole body) and evaluated functional and biochemical hallmarks of AD. We performed behavioral tests in the water maze (WM) before irradiation and in the WM and Barnes maze at 3 and 6 months post-irradiation to evaluate spatial learning and memory. We also performed electrophysiological recordings in vitro in hippocampal slices prepared 6 and 9 months post-irradiation to evaluate excitatory synaptic transmission and plasticity. Next, we evaluated amyloid beta (Abeta) deposition in the contralateral hippocampus and adjacent cortex using immunohistochemistry. In cortical homogenates, we analyzed the levels of the presynaptic marker synaptophysin by Western blotting and measured pro-inflammatory cytokine levels (TNFalpha, IL-1beta, IL-6, CXCL10 and CCL2) by bead-based multiplex assay. TG mice performed significantly worse than WT mice in the WM. Irradiation of TG mice did not affect their behavioral performance, but reduced the amplitudes of population spikes and inhibited paired-pulse facilitation in CA1 neurons. These electrophysiological alterations in the TG mice were qualitatively different from those observed in WT mice, in which irradiation increased excitability and synaptic efficacy. Irradiation increased Abeta deposition in the cortex of TG mice without affecting cytokine levels and increased synaptophysin expression in WT mice (but not in the TG mice). Although irradiation with protons increased Abeta deposition, the complex functional and biochemical results indicate that irradiation effects are not synergistic to AD pathology. PMID- 29186133 TI - Mutational analysis of ITPR1 in a Taiwanese cohort with cerebellar ataxias. AB - BACKGROUND: The inositol 1,4,5-triphosphate (IP3) receptor type 1 gene (ITPR1) encodes the IP3 receptor type 1 (IP3R1), which modulates intracellular calcium homeostasis and signaling. Mutations in ITPR1 have been implicated in inherited cerebellar ataxias. The aim of this study was to investigate the role of ITPR1 mutations, including both large segmental deletion and single nucleotide mutations, in a Han Chinese cohort with inherited cerebellar ataxias in Taiwan. METHODOLOGY AND PRINCIPAL FINDINGS: Ninety-three unrelated individuals with molecularly unassigned spinocerebellar ataxia selected from 585 pedigrees with autosomal dominant cerebellar ataxias, were recruited into the study with elaborate clinical evaluations. The quantitative PCR technique was used to survey large segmental deletion of ITPR1 and a targeted sequencing approach was applied to sequence all of the 61 exons and the flanking regions of ITPR1. A novel ITPR1 mutation, c.7721T>C (p.V2574A), was identified in a family with dominantly inherited cerebellar ataxia. The proband has an adult-onset non-progressive pure cerebellar ataxia and her daughter is afflicted with a childhood onset cerebellar ataxia with intellectual sub-normalities. CONCLUSION: ITPR1 mutation is an uncommon cause of inherited cerebellar ataxia, accounting for 0.2% (1/585) of patients with dominantly inherited cerebellar ataxias in Taiwan. This study broadens the mutational spectrum of ITPR1 and also emphasizes the importance of considering ITPR1 mutations as a potential cause of inherited cerebellar ataxias. PMID- 29186134 TI - An accurate and adaptable photogrammetric approach for estimating the mass and body condition of pinnipeds using an unmanned aerial system. AB - Measurements of body size and mass are fundamental to pinniped population management and research. Manual measurements tend to be accurate but are invasive and logistically challenging to obtain. Ground-based photogrammetric techniques are less invasive, but inherent limitations make them impractical for many field applications. The recent proliferation of unmanned aerial systems (UAS) in wildlife monitoring has provided a promising new platform for the photogrammetry of free-ranging pinnipeds. Leopard seals (Hydrurga leptonyx) are an apex predator in coastal Antarctica whose body condition could be a valuable indicator of ecosystem health. We aerially surveyed leopard seals of known body size and mass to test the precision and accuracy of photogrammetry from a small UAS. Flights were conducted in January and February of 2013 and 2014 and 50 photogrammetric samples were obtained from 15 unrestrained seals. UAS-derived measurements of standard length were accurate to within 2.01 +/- 1.06%, and paired comparisons with ground measurements were statistically indistinguishable. An allometric linear mixed effects model predicted leopard seal mass within 19.40 kg (4.4% error for a 440 kg seal). Photogrammetric measurements from a single, vertical image obtained using UAS provide a noninvasive approach for estimating the mass and body condition of pinnipeds that may be widely applicable. PMID- 29186136 TI - Development of a shear force measurement dummy for seat comfort. AB - Seat comfort is one of the main factors that consumers consider when purchasing a car. In this study, we develop a dummy with a shear-force sensor to evaluate seat comfort. The sensor has dimensions of 25 mm * 25 mm * 26 mm and is made of S45C. Electroless nickel plating is employed to coat its surface in order to prevent corrosion and oxidation. The proposed sensor is validated using a qualified load cell and shows high accuracy and precision (measurement range: -30-30 N; sensitivity: 0.1 N; linear relationship: R = 0.999; transverse sensitivity: <1%). The dummy is manufactured in compliance with the SAE standards (SAE J826) and incorporates shear sensors into its design. We measure the shear force under four driving conditions and at five different speeds using a sedan; results showed that the shear force increases with speed under all driving conditions. In the case of acceleration and deceleration, shear force significantly changes in the lower body of the dummy. During right and left turns, it significantly changes in the upper body of the dummy. PMID- 29186135 TI - Regulation of actions and habits by ventral hippocampal trkB and adolescent corticosteroid exposure. AB - In humans and rodents, stress promotes habit-based behaviors that can interfere with action-outcome decision-making. Further, developmental stressor exposure confers long-term habit biases across rodent-primate species. Despite these homologies, mechanisms remain unclear. We first report that exposure to the primary glucocorticoid corticosterone (CORT) in adolescent mice recapitulates multiple neurobehavioral consequences of stressor exposure, including long lasting biases towards habit-based responding in a food-reinforced operant conditioning task. In both adolescents and adults, CORT also caused a shift in the balance between full-length tyrosine kinase receptor B (trkB) and a truncated form of this neurotrophin receptor, favoring the inactive form throughout multiple corticolimbic brain regions. In adolescents, phosphorylation of the trkB substrate extracellular signal-regulated kinase 42/44 (ERK42/44) in the ventral hippocampus was also diminished, a long-term effect that persisted for at least 12 wk. Administration of the trkB agonist 7,8-dihydroxyflavone (7,8-DHF) during adolescence at doses that stimulated ERK42/44 corrected long-lasting corticosterone-induced behavioral abnormalities. Meanwhile, viral-mediated overexpression of truncated trkB in the ventral hippocampus reduced local ERK42/44 phosphorylation and was sufficient to induce habit-based and depression like behaviors. Together, our findings indicate that ventral hippocampal trkB is essential to goal-directed action selection, countering habit-based behavior otherwise facilitated by developmental stress hormone exposure. They also reveal an early-life sensitive period during which trkB-ERK42/44 tone determines long term behavioral outcomes. PMID- 29186137 TI - Evaluation of the implementation fidelity of the seasonal malaria chemoprevention intervention in Kaya health district, Burkina Faso. AB - BACKGROUND: Burkina Faso implemented the seasonal malaria chemoprevention (SMC) in 2014 in seven pilot health districts, following the new recommendation by the WHO in 2012 for the prevention of the disease in children under five years old, for areas of highly seasonal malaria transmission.The objective of this study was to assess the implementation fidelity of the seasonal malaria chemoprevention strategy in one of the districts, Kaya Health District. METHODOLOGY: We conducted a case study, with a quantitative and qualitative mixed methods. Data were collected after two campaigns of implementation of the intervention, in 2014 and 2015, through a review of specific documents of SMC intervention, and individual interview with key informants (n = 21) involved at various levels in the implementation of the strategy and a household survey with the parents (n = 284) of eligible children for the SMC strategy in 2015 in the Kaya health district. The analysis framework focused on the fidelity of the intervention's content, its coverage, and its schedule, as well as the potential moderating factors, using the model proposed by Hasson, originally from Carroll. RESULTS: All components of the intervention were implemented. Villages and sectors were covered at 100%. In terms of intervention doses received, less than one-third of eligible children (32.3%) received the recommended four doses in 2015. Implementation of the strategy faced some difficulties due to insufficient training of community distributors, inadequate supply of inputs and insufficient financial resources for remuneration, advocacy and supervision, but also because of the contextual constraints due to the rainy season. Moreover, an interaction between the different moderating factors, influencing the degree of implementation of the strategy was noted. CONCLUSION: Taking into account the moderating factors of the implementation is necessary for achieving the highest possible degree of implementation fidelity and then, reach the expected beneficial effects. PMID- 29186138 TI - Biodiversity conservation values of fragmented communally reserved forests, managed by indigenous people, in a human-modified landscape in Borneo. AB - This study explored the conservation values of communally reserved forests (CRFs), which local indigenous communities deliberately preserve within their area of shifting cultivation. In the current landscape of rural Borneo, CRFs are the only option for conservation because other forested areas have already been logged or transformed into plantations. By analyzing their alpha and beta diversity, we investigated how these forests can contribute to restore regional biodiversity. Although CRFs were fragmented and some had been disturbed in the past, their tree species diversity was high and equivalent to that of primary forests. The species composition of intact forests and forests disturbed in the past did not differ clearly, which indicates that past logging was not intensive. All CRFs contained unique and endangered species, which are on the IUCN Red List, Sarawak protected plants, or both. On the other hand, the forest size structure differed between disturbed and intact CRFs, with the disturbed CRFs consisting of relatively smaller trees. Although the beta diversity among CRFs was also high, we found a high contribution of species replacement (turnover), but not of richness difference, in the total beta diversity. This suggests that all CRFs have a conservation value for restoring the overall regional biodiversity. Therefore, for maintaining the regional species diversity and endangered species, it would be suitable to design a conservation target into all CRFs. PMID- 29186140 TI - Phylogeography of the termite Macrotermes gilvus and insight into ancient dispersal corridors in Pleistocene Southeast Asia. AB - Dispersal of soil-dwelling organisms via the repeatedly exposed Sunda shelf through much of the Pleistocene in Southeast Asia has not been studied extensively, especially for invertebrates. Here we investigated the phylogeography of an endemic termite species, Macrotermes gilvus (Hagen), to elucidate the spatiotemporal dynamics of dispersal routes of terrestrial fauna in Pleistocene Southeast Asia. We sampled 213 termite colonies from 66 localities throughout the region. Independently inherited microsatellites and mtDNA markers were used to infer the phylogeographic framework of M. gilvus. Discrete phylogeographic analysis and molecular dating based on fossil calibration were used to infer the dynamics of M. gilvus dispersal in time and space across Southeast Asia. We found that the termite dispersal events were consistently dated within the Pleistocene time frame. The dispersal pattern was multidirectional, radiating eastwards and southwards out of Indochina, which was identified as the origin for dispersal events. We found no direct dispersal events between Sumatra and Borneo despite the presence of a terrestrial connection between them during the Pleistocene. Instead, central Java served as an important link allowing termite colonies to be established in Borneo and Sumatra. Our findings support the hypothesis of a north-south dispersal corridor in Southeast Asia and suggest the presence of alternative dispersal routes across Sundaland during the Pleistocene. For the first time, we also propose that a west east dispersal through over-water rafting likely occurred across the Pleistocene South China Sea. We found at least two independent entry routes for terrestrial species to infiltrate Sumatra and Borneo at different times. PMID- 29186139 TI - Identification and characterization of novel cecropins from the Oxysternon conspicillatum neotropic dung beetle. AB - Dung beetles are exposed to a complex microbiological ecosystem during their life cycle. Characterization of novel host-defense peptides (HDP) is essential to understanding the host innate immune response in insects. It constitutes a promising alternative to look for new therapeutic agents against pathogenic microbes. We identified four new HDP, Oxysterlins 1, 2, 3, and 4 from the transcriptome of the Oxysternon conspicillatum dung beetle. These HDP display a highly conserved signal peptide and a mature peptide, characterized by an overall positive charge (cationic) (pI: 10.23-11.49), a hydrophobic ratio (PhiH: 35-41), and amphipathicity. Oxysterlins 1, 2, and 3 have a linear alpha-helix structure, whilst Oxysterlin 4 has a mixture of both alpha-helix and beta-sheet structures without disulfide bonds through bioinformatics prediction and circular dichroism. Oxysterlins are part of the cecropin family group in an exclusive clade related to beetle cecropins. They have predominant antimicrobial activity against Gram negative bacteria, including multidrug resistant strains (3.12-50 MUg/mL) measured by plate microdilution. Their kinetics, in a time-killing curve showed concentration-dependent bactericidal activity. Furthermore, these HDP have low toxicity against human erythrocytes (62.5-500 MUg/mL) and Vero cells (250-500 MUg/mL).

AB - Publication metadata help deliver rich analyses of scholarly communication. However, research concepts and ideas are more effectively expressed through unstructured fields such as full texts. Thus, the goals of this paper are to employ a full-text enabled method to extract terms relevant to disciplinary vocabularies, and through them, to understand the relationships between disciplines. This paper uses an efficient, domain-independent term extraction method to extract disciplinary vocabularies from a large multidisciplinary corpus of PLoS ONE publications. It finds a power-law pattern in the frequency distributions of terms present in each discipline, indicating a semantic richness potentially sufficient for further study and advanced analysis. The salient relationships amongst these vocabularies become apparent in application of a principal component analysis. For example, Mathematics and Computer and Information Sciences were found to have similar vocabulary use patterns along with Engineering and Physics; while Chemistry and the Social Sciences were found to exhibit contrasting vocabulary use patterns along with the Earth Sciences and Chemistry. These results have implications to studies of scholarly communication as scholars attempt to identify the epistemological cultures of disciplines, and as a full text-based methodology could lead to machine learning applications in the automated classification of scholarly work according to disciplinary vocabularies. PMID- 29186142 TI - Breastfeeding and maternal cardiovascular risk factors and outcomes: A systematic review. AB - BACKGROUND: There is growing evidence that breastfeeding has short- and long-term cardiovascular health benefits for mothers. The objectives of this systematic review were to examine the association between breastfeeding and maternal cardiovascular risk factors and outcomes that have not previously been synthesized systematically, including metabolic syndrome, hypertension and cardiovascular disease. METHODS AND FINDINGS: This systematic review meets PRISMA guidelines. The MEDLINE, EMBASE and CINAHL databases were systematically searched for relevant publications of any study design from the earliest publication date to March 2016. The reference lists from selected articles were reviewed, and forward and backward referencing were conducted. The methodological quality of reviewed articles was appraised using validated checklists. Twenty-one studies meeting the inclusion criteria examined the association between self-reported breastfeeding and one or more of the following outcomes: metabolic syndrome/metabolic risk factors (n = 10), inflammatory markers/adipokines (n = 2), hypertension (n = 7), subclinical cardiovascular disease (n = 2), prevalence/incidence of cardiovascular disease (n = 3) and cardiovascular disease mortality (n = 2). Overall, 19 studies (10 cross-sectional/retrospective, 9 prospective) reported significant protective effects of breastfeeding, nine studies (3 cross-sectional/retrospective, 5 prospective, 1 cluster randomized controlled trial) reported non-significant findings and none reported detrimental effects of breastfeeding. In most studies reporting significant associations, breastfeeding remained associated with both short- and long-term maternal cardiovascular health risk factors/outcomes, even after covariate adjustment. Findings from several studies suggested that the effects of breastfeeding may diminish with age and a dose-response association between breastfeeding and several metabolic risk factors. However, further longitudinal studies, including studies that measure exclusive breastfeeding, are needed to confirm these findings. CONCLUSIONS: The evidence from this review suggests that breastfeeding is associated with cardiovascular health benefits. However, results should be interpreted with caution as the evidence gathered for each individual outcome was limited by the small number of observational studies. Additional prospective studies are needed. PROSPERO REGISTRATION NUMBER: CRD42016047766.

AB - Many dinoflagellate microalgae of the genus Symbiodinium form successful symbioses with a large group of metazoans and selected protists. Yet knowledge of growth kinetics of these endosymbionts and their ecological and evolutionary implications is limited. We used a Bayesian biphasic generalized logistic model to estimate key parameters of the growth of five strains of cultured Symbiodinium, S. microadriaticum (cp-type A194; strain 04-503), S. microadriaticum (cp-type A194; strain CassKB8), S. minutum (cp-type B184; strain Mf 1.05b.01.SCI.01), S. psygmophilum (cp-type B224; strain Mf 11.05b.01) and S. trenchii (cp-type D206; strain Mf 2.2b), grown in four different combinations of temperature and light. Growth kinetics varied among Symbiodinium strains and across treatments. Biphasic growth was especially evident for S. minutum and S. psygmophilum across all treatments. Monophasic growth was more common when final asymptotic densities were relatively low (~ 200 million cells ml-1). All species tended to grow faster and / or reached a higher asymptote at 26 degrees C than at 18 degrees C. The fastest growth was exhibited by S. minutum, with an approximate four-fold increase in estimated cell density after 60 days. The strongest effect of light was seen in S. trenchii, in which increasing light levels resulted in a decrease in initial growth rate, and an increase in asymptotic density, time when growth rate was at its maximum, final growth rate, and maximum growth rate. Results suggest that Symbiodinium species have different photokinetic and thermal optima, which may affect their growth-related nutritional physiology and allow them to modify their response to environmental changes. PMID- 29186144 TI - Time trends in antibiotic consumption in the elderly: Ten-year follow-up of the Spanish National Health Survey and the European Health Interview Survey for Spain (2003-2014). AB - BACKGROUND: The purposes of this study were: firstly, to estimate time trends in the prevalence of prescription antibiotic consumption between 2003 and 2014; secondly, to identify the factors associated with the probability of consuming antibiotics during this period in elderly persons in Spain. METHODS: We analyzed data collected from the Spanish National Health Survey in 2003 (n = 21,650), 2006 (n = 29,478), and 2012 (n = 20,007) and from the European Health Interview Survey for Spain in 2009 (n = 22,188) and 2014 (n = 22,842). Antibiotic consumption was the dependent variable. We also analyzed sociodemographic features, self perceived health status, lifestyle habits, comorbid diseases, and disabilities using logistic regression models. RESULTS: The prevalence of antibiotic consumption increased from 2003 to 2014 in both sexes. The variables that predicted antibiotic consumption (men; women) were secondary education (OR 1.38; OR 1.31), visits to a general practitioner (OR 2.05; OR 2.15), hospitalization (OR 1.91; OR 1.83), therapy with > 4 non-antibiotic drugs (OR 3.36; OR 5.84), instrumental activities of daily living (OR 1.50; OR 1.24), and activities of daily living (OR 1.39; OR 1.35). In contrast, age > 85 years was associated with low antibiotic consumption in both men (OR 0.81) and women (OR 0.88). CONCLUSIONS: The prevalence of antibiotic prescription has increased in Spain in the last decade. Our study identified several factors that appear to affect antibiotic consumption in elderly persons, with potential implications for healthcare providers. PMID- 29186145 TI - Respective impact of implementation of prevention strategies, colonization with multiresistant bacteria and antimicrobial use on the risk of early- and late onset VAP: An analysis of the OUTCOMEREA network. AB - RATIONALE: The impact of prevention strategies and risk factors for early-onset (EOP) versus late-onset (LOP) ventilator-associated pneumonia (VAP) are still debated. OBJECTIVES: To evaluate, in a multicenter cohort, the risk factors for EOP and LOP, as the evolution of prevention strategies. METHODS: 7,784 patients with mechanical ventilation (MV) for at least 48 hours were selected into the multicenter prospective OUTCOMEREA database (1997-2016). VAP occurring between the 3rd and 6th day of MV defined EOP, while those occurring after defined LOPs. We used a Fine and Gray subdistribution model to take the successful extubation into account as a competing event. MEASUREMENTS AND MAIN RESULTS: Overall, 1,234 included patients developed VAP (EOP: 445 (36%); LOP: 789 (64%)). Male gender was a risk factor for both EOP and LOP. Factors specifically associated with EOP were admission for respiratory distress, previous colonization with multidrug resistant Pseudomonas aeruginosa, chest tube and enteral feeding within the first 2 days of MV. Antimicrobials administrated within the first 2 days of MV were all protective of EOP. ICU admission for COPD exacerbation or pneumonia were early risk factors for LOP, while imidazole and vancomycin use within the first 2 days of MV were protective factors. Late risk factors (between the 3rd and the 6th day of MV) were the intra-hospital transport, PAO2-FIO2<200 mmHg, vasopressor use, and known colonization with methicillin-resistant Staphylococcus aureus. Among the antimicrobials administered between the 3rd and the 6th day, fluoroquinolones were the solely protective one.Contrarily to LOP, the risk of EOP decreased across the study time periods, concomitantly with an increase in the compliance with bundle of prevention measures. CONCLUSION: VAP risk factors are mostly different according to the pneumonia time of onset, which should lead to differentiated prevention strategies. PMID- 29186147 TI - Testing the Sensory Drive Hypothesis: Geographic variation in echolocation frequencies of Geoffroy's horseshoe bat (Rhinolophidae: Rhinolophus clivosus). AB - Geographic variation in sensory traits is usually influenced by adaptive processes because these traits are involved in crucial life-history aspects including orientation, communication, lineage recognition and mate choice. Studying this variation can therefore provide insights into lineage diversification. According to the Sensory Drive Hypothesis, lineage diversification may be driven by adaptation of sensory systems to local environments. It predicts that acoustic signals vary in association with local climatic conditions so that atmospheric attenuation is minimized and transmission of the signals maximized. To test this prediction, we investigated the influence of climatic factors (specifically relative humidity and temperature) on geographic variation in the resting frequencies of the echolocation pulses of Geoffroy's horseshoe bat, Rhinolophus clivosus. If the evolution of phenotypic variation in this lineage tracks climate variation, human induced climate change may lead to decreases in detection volumes and a reduction in foraging efficiency. A complex non-linear interaction between relative humidity and temperature affects atmospheric attenuation of sound and principal components composed of these correlated variables were, therefore, used in a linear mixed effects model to assess their contribution to observed variation in resting frequencies. A principal component composed predominantly of mean annual temperature (factor loading of -0.8455) significantly explained a proportion of the variation in resting frequency across sites (P < 0.05). Specifically, at higher relative humidity (around 60%) prevalent across the distribution of R. clivosus, increasing temperature had a strong negative effect on resting frequency. Climatic factors thus strongly influence acoustic signal divergence in this lineage, supporting the prediction of the Sensory Drive Hypothesis. The predicted future increase in temperature due to climate change is likely to decrease the detection volume in echolocating bats and adversely impact their foraging efficiency. PMID- 29186146 TI - Auditory and cognitive performance in elderly musicians and nonmusicians. AB - Musicians represent a model for examining brain and behavioral plasticity in terms of cognitive and auditory profile, but few studies have investigated whether elderly musicians have better auditory and cognitive abilities than nonmusicians. The aim of the present study was to examine whether being a professional musician attenuates the normal age-related changes in hearing and cognition. Elderly musicians still active in their profession were compared with nonmusicians on auditory performance (absolute threshold, frequency intensity, duration and spectral shape discrimination, gap and sinusoidal amplitude modulation detection), and on simple (short-term memory) and more complex and higher-order (working memory [WM] and visuospatial abilities) cognitive tasks. The sample consisted of adults at least 65 years of age. The results showed that older musicians had similar absolute thresholds but better supra-threshold discrimination abilities than nonmusicians in four of the six auditory tasks administered. They also had a better WM performance, and stronger visuospatial abilities than nonmusicians. No differences were found between the two groups' short-term memory. Frequency discrimination and gap detection for the auditory measures, and WM complex span tasks and one of the visuospatial tasks for the cognitive ones proved to be very good classifiers of the musicians. These findings suggest that life-long music training may be associated with enhanced auditory and cognitive performance, including complex cognitive skills, in advanced age. However, whether this music training represents a protective factor or not needs further investigation. PMID- 29186148 TI - A case-control collapsing analysis identifies epilepsy genes implicated in trio sequencing studies focused on de novo mutations. AB - Trio exome sequencing has been successful in identifying genes with de novo mutations (DNMs) causing epileptic encephalopathy (EE) and other neurodevelopmental disorders. Here, we evaluate how well a case-control collapsing analysis recovers genes causing dominant forms of EE originally implicated by DNM analysis. We performed a genome-wide search for an enrichment of "qualifying variants" in protein-coding genes in 488 unrelated cases compared to 12,151 unrelated controls. These "qualifying variants" were selected to be extremely rare variants predicted to functionally impact the protein to enrich for likely pathogenic variants. Despite modest sample size, three known EE genes (KCNT1, SCN2A, and STXBP1) achieved genome-wide significance (p<2.68*10-6). In addition, six of the 10 most significantly associated genes are known EE genes, and the majority of the known EE genes (17 out of 25) originally implicated in trio sequencing are nominally significant (p<0.05), a proportion significantly higher than the expected (Fisher's exact p = 2.33*10-17). Our results indicate that a case-control collapsing analysis can identify several of the EE genes originally implicated in trio sequencing studies, and clearly show that additional genes would be implicated with larger sample sizes. The case-control analysis not only makes discovery easier and more economical in early onset disorders, particularly when large cohorts are available, but also supports the use of this approach to identify genes in diseases that present later in life when parents are not readily available. PMID- 29186149 TI - The alkalophilic fungus Sodiomyces alkalinus hosts beta- and gammapartitiviruses together with a new fusarivirus. AB - Mixed infection by three dsRNA viruses, a novel betapartitivirus, a gammapartitivirus, and a novel fusarivirus, has been identified in four isolates of the obligate alkalophilic fungus Sodiomyces alkalinus. The first, Sodiomyces alkalinus partitivirus 1 (SaPV1), is placed within the genus Betapartitivirus and is related to Ustilaginoidea virens partitivirus 2. The taxonomic position of the second virus is less clear as it shares high (85%) amino acid sequence identity but significantly low (77%) nucleotide sequence identity of the capsid protein with Colletotrichum truncatum partitivirus 1. The third, the novel Sodiomyces alkalinus fusarivirus 1 (SaFV1), is related to Fusarium poae fusarivirus 1. All the viruses show efficient vertical transmission through asexual and sexual spores. These novel coexisting viruses do not evoke apparent phenotypic alteration to their fungal host. This is the first description of a viral infection in an alkalophilic fungus. PMID- 29186150 TI - In vitro enteroid-derived three-dimensional tissue model of human small intestinal epithelium with innate immune responses. AB - There is a need for functional in vitro 3D human intestine systems that can bridge the gap between conventional cell culture studies and human trials. The successful engineering in vitro of human intestinal tissues relies on the use of the appropriate cell sources, biomimetic scaffolds, and 3D culture conditions to support vital organ functions. We previously established a compartmentalized scaffold consisting of a hollow space within a porous bulk matrix, in which a functional and physiologically relevant intestinal epithelium system was generated using intestinal cell lines. In this study, we adopt the 3D scaffold system for the cultivation of stem cell-derived human small intestinal enteriods (HIEs) to engineer an in vitro 3D model of a nonstransformed human small intestinal epithelium. Characterization of tissue properties revealed a mature HIE-derived epithelium displaying four major terminally differentiated epithelial cell types (enterocytes, Goblet cells, Paneth cells, enteroendocrine cells), with tight junction formation, microvilli polarization, digestive enzyme secretion, and low oxygen tension in the lumen. Moreover, the tissue model demonstrates significant antibacterial responses to E. coli infection, as evidenced by the significant upregulation of genes involved in the innate immune response. Importantly, many of these genes are activated in human patients with inflammatory bowel disease (IBD), implicating the potential application of the 3D stem-cell derived epithelium for the in vitro study of host-microbe-pathogen interplay and IBD pathogenesis. PMID- 29186151 TI - Difference between ejection times measured at two different peripheral locations as a novel marker of vascular stiffness. AB - Pulse wave velocity (PWV) has been recommended as an arterial damage assessment tool and a surrogate of arterial stiffness. However, the current technology does not allow to measure PWV both continuously and in real-time. We reported previously that peripherally measured ejection time (ET) overestimates ET measured centrally. This difference in ET is associated with the inherent vascular properties of the vessel. In the current study we examined ETs derived from plethysmography simultaneously at different peripheral locations and examined the influence of the underlying arterial properties on ET prolongation by changing the subject's position. We calculated the ET difference between two peripheral locations (DeltaET) and its corresponding PWV for the same heartbeat. The DeltaET increased with a corresponding decrease in PWV. The difference between DeltaET in the supine and standing (which we call ET index) was higher in young subjects with low mean arterial pressure and low PWV. These results suggest that the difference in ET between two peripheral locations in the supine vs standing positions represents the underlying vascular properties. We propose DeltaET in the supine position as a potential novel real-time continuous and non invasive parameter of vascular properties, and the ET index as a potential non invasive parameter of vascular reactivity. PMID- 29186153 TI - The peer review gap: A longitudinal case study of gendered publishing and occupational patterns in a female-rich discipline, Western North America (1974 2016). AB - Researchers have repeatedly demonstrated that women continue to be underrepresented in publication output in the sciences. This is true even in female-rich fields such as archaeology. Since most gender-related publication studies rely on data from peer-reviewed journals, it would be instructive, though challenging, to also track publication output in non-refereed and professional or industry venues, which tend to be more accessible to those working in extra academic settings. This comparison is important in fields such as archaeology in which the vast majority (approximately 90%) of practitioners in the USA work for private sector cultural resource management firms and federal and state agencies. To understand the dynamics of who publishes where, we compiled a new dataset tracking over 40 years of peer-reviewed versus non-peer-reviewed publications that publish articles on the archaeology of California (an American Indian cultural area including southwest Oregon, most of the state of California, and Baja Mexico) and the Great Basin culture area (spanning eight western USA states). Historic gender differences in the publishing output of authors identified as men versus those identified as women were revealed by articles published between 1974 and 2016 in two refereed journals, the Journal of California Anthropology/ Journal of California and Great Basin Anthropology and California Archaeology, and in one un-refereed venue, the Society for California Archaeology Proceedings. Although multiple independent measures indicate that women are contributing and active members of the discipline, publishing records yield more variable results. Specifically, while women have historic and increasingly robust levels of participation in the non-peer-reviewed Proceedings, they remain vastly underrepresented in the two peer-reviewed journals, which are widely regarded as more prestigious and influential. We argue that this "peer review gap" is influenced by variation in the costs (largely time investment) and benefits of publication for people working in different professional roles (e.g., agency professionals, private/cultural resource management firm personnel, tenure track faculty, adjunct faculty, etc.). We also argue that these cost and benefit variations may ultimately influence the decisions of people of all genders and backgrounds, but, because of the current structure of our discipline-including the fact that women and minorities lag in positions where costly peer-reviewed publication is a rewarded and supported activity-overwhelmingly affect these groups. We recognize that non-refereed publications such as Proceedings provide an important means of bridging the peer review gap and give voice to individuals from diverse backgrounds and perspectives. PMID- 29186154 TI - External validation of a collar-mounted triaxial accelerometer for second-by second monitoring of eight behavioural states in dogs. AB - Early detection of disease by an animal owner may motivate them to seek early veterinary advice. Presentation before a more advanced clinical manifestation is evident could lead to more effective treatment and thus benefit the animal's health and welfare. Accelerometers are able to detect changes in specific activities or behaviours, thus indicating early signs of possible adverse health events. The objective of this validation study was to determine whether the detection of eight behavioural states: walk, trot, canter/gallop, sleep, static/inactive, eat, drink, and headshake, by an accelerometer device was sufficiently accurate to be useful in a clinical setting. This fully independent external validation estimated the accuracy of a specific triaxial, collar-mounted accelerometer on a second-by second basis in 51 healthy dogs of different breeds, aged between 6 months and 13 years, weighing >10 kg. The overall diagnostic effectiveness was estimated as: % record correctly classified of > 95% in walk, trot, canter/gallop, eat, drink and headshake and >90% in sleep and static/inactive. The positive predictive values ranged from 93-100%, while the negative predictive values ranged from 96-100%, with exception of static/inactive (86%).This was probably because dogs were placed in unfamiliar kennels where they did not exhibit their typical resting behaviour. The device is worn on a collar, making its use feasible for anyone wanting to monitor their dog's behaviour. The high accuracy in detecting various kinds of behaviour appears promising in assessing canine health and welfare states. PMID- 29186152 TI - High-throughput full-length single-cell mRNA-seq of rare cells. AB - Single-cell characterization techniques, such as mRNA-seq, have been applied to a diverse range of applications in cancer biology, yielding great insight into mechanisms leading to therapy resistance and tumor clonality. While single-cell techniques can yield a wealth of information, a common bottleneck is the lack of throughput, with many current processing methods being limited to the analysis of small volumes of single cell suspensions with cell densities on the order of 107 per mL. In this work, we present a high-throughput full-length mRNA-seq protocol incorporating a magnetic sifter and magnetic nanoparticle-antibody conjugates for rare cell enrichment, and Smart-seq2 chemistry for sequencing. We evaluate the efficiency and quality of this protocol with a simulated circulating tumor cell system, whereby non-small-cell lung cancer cell lines (NCI-H1650 and NCI-H1975) are spiked into whole blood, before being enriched for single-cell mRNA-seq by EpCAM-functionalized magnetic nanoparticles and the magnetic sifter. We obtain high efficiency (> 90%) capture and release of these simulated rare cells via the magnetic sifter, with reproducible transcriptome data. In addition, while mRNA seq data is typically only used for gene expression analysis of transcriptomic data, we demonstrate the use of full-length mRNA-seq chemistries like Smart-seq2 to facilitate variant analysis of expressed genes. This enables the use of mRNA seq data for differentiating cells in a heterogeneous population by both their phenotypic and variant profile. In a simulated heterogeneous mixture of circulating tumor cells in whole blood, we utilize this high-throughput protocol to differentiate these heterogeneous cells by both their phenotype (lung cancer versus white blood cells), and mutational profile (H1650 versus H1975 cells), in a single sequencing run. This high-throughput method can help facilitate single cell analysis of rare cell populations, such as circulating tumor or endothelial cells, with demonstrably high-quality transcriptomic data. PMID- 29186155 TI - Using iterative learning to improve understanding during the informed consent process in a South African psychiatric genomics study. AB - Obtaining informed consent is a great challenge in global health research. There is a need for tools that can screen for and improve potential research participants' understanding of the research study at the time of recruitment. Limited empirical research has been conducted in low and middle income countries, evaluating informed consent processes in genomics research. We sought to investigate the quality of informed consent obtained in a South African psychiatric genomics study. A Xhosa language version of the University of California, San Diego Brief Assessment of Capacity to Consent Questionnaire (UBACC) was used to screen for capacity to consent and improve understanding through iterative learning in a sample of 528 Xhosa people with schizophrenia and 528 controls. We address two questions: firstly, whether research participants' understanding of the research study improved through iterative learning; and secondly, what were predictors for better understanding of the research study at the initial screening? During screening 290 (55%) cases and 172 (33%) controls scored below the 14.5 cut-off for acceptable understanding of the research study elements, however after iterative learning only 38 (7%) cases and 13 (2.5%) controls continued to score below this cut-off. Significant variables associated with increased understanding of the consent included the psychiatric nurse recruiter conducting the consent screening, higher participant level of education, and being a control. The UBACC proved an effective tool to improve understanding of research study elements during consent, for both cases and controls. The tool holds utility for complex studies such as those involving genomics, where iterative learning can be used to make significant improvements in understanding of research study elements. The UBACC may be particularly important in groups with severe mental illness and lower education levels. Study recruiters play a significant role in managing the quality of the informed consent process. PMID- 29186156 TI - A common mechanism by which type 2A von Willebrand disease mutations enhance ADAMTS13 proteolysis revealed with a von Willebrand factor A2 domain FRET construct. AB - Rheological forces in the blood trigger the unfolding of von Willebrand factor (VWF) and its A2 domain, exposing the scissile bond for proteolysis by ADAMTS13. Under quiescent conditions, the scissile bond is hidden by the folded structure due to the stabilisation provided by the structural specialisations of the VWF A2 domain, a vicinal disulphide bond, a calcium binding site and a N1574-glycan.The reduced circulating high MW multimers of VWF in patients with type 2A von Willebrand disease (VWD) may be associated with mutations within the VWF A2 domain and this is attributed to enhanced ADAMTS13 proteolysis. We investigated 11 VWF A2 domain variants identified in patients with type 2A VWD. In recombinant full-length VWF, enhanced ADAMTS13 proteolysis was detected for all of the expressed variants in the presence of urea-induced denaturation. A subset of the FLVWF variants displayed enhanced proteolysis in the absence of urea. The mechanism of enhancement was investigated using a novel VWF A2 domain FRET construct. In the absence of induced unfolding, 7/8 of the expressed mutants exhibited a disrupted domain fold, causing spatial separation of the N- and C- termini. Three of the type 2A mutants were not secreted when studied within the VWF A2 domain FRET construct. Urea denaturation revealed for all 8 secreted mutants reduced unfolding cooperativity and stability of the VWF A2 domain. As folding stability was progressively disrupted, proteolysis by ADAMTS13 increased. Due to the range of folding stabilities and wide distribution of VWF A2 domain mutations studied, we conclude that these mutations disrupt regulated folding of the VWF A2 domain. They enhance unfolding by inducing separation of N- and C termini, thereby promoting a more open conformation that reveals its binding sites for ADAMTS13 and the scissile bond. PMID- 29186158 TI - Determinants and effects of medical students' core self-evaluation tendencies on clinical competence and workplace well-being in clerkship. AB - Core self-evaluation (CSE) is a personality trait that involves a person's evaluation of his or her own worth, competence, and capability. The objective of this study was to determine whether medical students' CSEs exert beneficial effects on their adaptation to their clerkship in terms of their clinical competence and workplace well-being and whether their preclinical academic performance can be a trait-relevant situation that enhances their CSE expression. In total, 127 medical students from 2 cohorts were included as participants in this study. We analyzed complete measures of personal background, objective and subjective preclinical academic performance (course evaluation grades and self reported efficacy), CSE tendencies, and clinical competence (as objective structured clinical examination scores) and workplace well-being (as compassion satisfaction and burnout) during their 2-year clerkship. Mixed linear models for repeated measures and multiple regressions were employed. Participants' CSE tendencies had positive effects on their workplace compassion satisfaction and burnout but not on their clinical competence during their clerkship. Additionally, using the objective and subjective preclinical academic performance of the medical students as indicators, we observed that neither could be trait relevant situations to enhance their CSE expression. CSE personality tendencies might be key to medical students' ability to noncognitively adapt to clinical training during their clerkships. These tendencies should be identified earlier so that mentors can provide prompt care and support to mentees (medical students) during clerkships. PMID- 29186157 TI - Finite element simulation and clinical follow-up of lumbar spine biomechanics with dynamic fixations. AB - Arthrodesis is a recommended treatment in advanced stages of degenerative disc disease. Despite dynamic fixations were designed to prevent abnormal motions with better physiological load transmission, improving lumbar pain and reducing stress on adjacent segments, contradictory results have been obtained. This study was designed to compare differences in the biomechanical behaviour between the healthy lumbar spine and the spine with DYNESYS and DIAM fixation, respectively, at L4-L5 level. Behaviour under flexion, extension, lateral bending and axial rotation are compared using healthy lumbar spine as reference. Three 3D finite element models of lumbar spine (healthy, DYNESYS and DIAM implemented, respectively) were developed, together a clinical follow-up of 58 patients operated on for degenerative disc disease. DYNESYS produced higher variations of motion with a maximum value for lateral bending, decreasing intradiscal pressure and facet joint forces at instrumented level, whereas screw insertion zones concentrated stress. DIAM increased movement during flexion, decreased it in another three movements, and produced stress concentration at the apophyses at instrumented level. Dynamic systems, used as single systems without vertebral fusion, could be a good alternative to degenerative disc disease for grade II and grade III of Pfirrmann. PMID- 29186159 TI - Predictors of seasonal influenza vaccination among older adults in Thailand. AB - BACKGROUND: In advance of a large influenza vaccine effectiveness (VE) cohort study among older adults in Thailand, we conducted a population-based, cross sectional survey to measure vaccine coverage and identify factors associated with influenza vaccination among older Thai adults that could bias measures of vaccine effectiveness. METHOD: We selected adults >=65 years using a two-stage, stratified, cluster sampling design. Functional status was assessed using the 10 point Vulnerable Elders Survey (VES); scores >=3 indicated vulnerability. Questions about attitudes towards vaccination were based on the Health Belief Model. The distance between participants' households and the nearest vaccination clinic was calculated. Vaccination status was determined using national influenza vaccination registry. Prevalence ratios (PR) and 95% confidence intervals (CIs) were calculated using log-binomial multivariable models accounting for the sampling design. RESULT: We enrolled 581 participants, of whom 60% were female, median age was 72 years, 41% had at least one chronic underlying illness, 24% met the criteria for vulnerable, and 23% did not leave the house on a daily basis. Influenza vaccination rate was 34%. In multivariable models, no variable related to functional status was associated with vaccination. The strongest predictors of vaccination were distance to the nearest vaccination center (PR 3.0, 95% CI 1.7 5.1 for participants in the closest quartile compared to the furthest), and high levels of a perception of benefits of influenza vaccination (PR 2.8, 95% CI 1.4 5.6) and cues to action (PR 2.7, 95% CI 1.5-5.1). CONCLUSION: Distance to vaccination clinics should be considered in analyses of influenza VE studies in Thailand. Strategies that emphasize benefits of vaccination and encourage physicians to recommend annual influenza vaccination could improve influenza vaccine uptake among older Thai adults. Outreach to more distant and less mobile older adults may also be required to improve influenza vaccination coverage. PMID- 29186160 TI - Community detection in dynamic networks via adaptive label propagation. AB - An adaptive label propagation algorithm (ALPA) is proposed to detect and monitor communities in dynamic networks. Unlike the traditional methods by re-computing the whole community decomposition after each modification of the network, ALPA takes into account the information of historical communities and updates its solution according to the network modifications via a local label propagation process, which generally affects only a small portion of the network. This makes it respond to network changes at low computational cost. The effectiveness of ALPA has been tested on both synthetic and real-world networks, which shows that it can successfully identify and track dynamic communities. Moreover, ALPA could detect communities with high quality and accuracy compared to other methods. Therefore, being low-complexity and parameter-free, ALPA is a scalable and promising solution for some real-world applications of community detection in dynamic networks. PMID- 29186161 TI - Enhancing reproducibility in scientific computing: Metrics and registry for Singularity containers. AB - Here we present Singularity Hub, a framework to build and deploy Singularity containers for mobility of compute, and the singularity-python software with novel metrics for assessing reproducibility of such containers. Singularity containers make it possible for scientists and developers to package reproducible software, and Singularity Hub adds automation to this workflow by building, capturing metadata for, visualizing, and serving containers programmatically. Our novel metrics, based on custom filters of content hashes of container contents, allow for comparison of an entire container, including operating system, custom software, and metadata. First we will review Singularity Hub's primary use cases and how the infrastructure has been designed to support modern, common workflows. Next, we conduct three analyses to demonstrate build consistency, reproducibility metric and performance and interpretability, and potential for discovery. This is the first effort to demonstrate a rigorous assessment of measurable similarity between containers and operating systems. We provide these capabilities within Singularity Hub, as well as the source software singularity-python that provides the underlying functionality. Singularity Hub is available at https://singularity hub.org, and we are excited to provide it as an openly available platform for building, and deploying scientific containers. PMID- 29186162 TI - Pore-forming activity of new conjugate antibiotics based on amphotericin B. AB - A series of amides of the antifungal antibiotic amphotericin B (AmB) and its conjugates with benzoxaboroles was tested to determine whether they form pores in lipid bilayers and to compare their channel characteristics. The tested derivatives produced pores of larger amplitude and shorter lifetime than those of the parent antibiotic. The pore conductance was related to changes in the partial charge of the hydrogens of the hydroxyl groups in the lactone ring that determined the anion coordination in the channel. Neutralization of one of the polar group charges in the AmB head during chemical modification produced a pronounced effect by diminishing the dwell time of the polyene channel compared to modification of both groups. In this study, compounds that had a modification of one carboxyl or amino group were less effective in initializing phase separation in POPC-membranes compared to derivatives that had modifications of both polar groups as well as the parent antibiotic. The effects were attributed to the restriction of the aggregation process by electrical repulsion between charged derivatives in contrast to neutral compounds. The significant correlation between the ability of derivatives to increase the permeability of model membranes-causing the appearance of single channels in lipid bilayers or inducing calcein leakage from unilamellar vesicles-and the minimal inhibitory concentration indicated that the antifungal effect of the conjugates was due to pore formation in the membranes of target cells.

AB - INTRODUCTION: The use of generic medicines is a cost-effective policy, often dictated by fiscal restraints. To our knowledge, no fully validated tool exploring the students' knowledge and attitudes towards generic medicines exists. The aim of our study was to develop and validate a questionnaire exploring the knowledge and attitudes of M.Sc. in Health Care Management students and recent alumni's towards generic drugs in Greece. MATERIALS AND METHODS: The development of the questionnaire was a result of literature review and pilot-testing of its preliminary versions to researchers and students. The final version of the questionnaire contains 18 items measuring the respondents' knowledge and attitude towards generic medicines on a 5-point Likert scale. Given the ordinal nature of the data, ordinal alpha and polychoric correlations were computed. The sample was randomly split into two halves. Exploratory factor analysis, performed in the first sample, was used for the creation of multi-item scales. Confirmatory factor analysis and Generalized Linear Latent and Mixed Model analysis (GLLAMM) with the use of the rating scale model were used in the second sample to assess goodness of fit. An assessment of internal consistency reliability, test-retest reliability, and construct validity was also performed. RESULTS: Among 1402 persons contacted, 986 persons completed our questionnaire (response rate = 70.3%). Overall Cronbach's alpha was 0.871. The conjoint use of exploratory and confirmatory factor analysis resulted in a six-scale model, which seemed to fit the data well. Five of the six scales, namely trust, drug quality, state audit, fiscal impact and drug substitution were found to be valid and reliable, while the knowledge scale suffered only from low inter-scale correlations and a ceiling effect. However, the subsequent confirmatory factor and GLLAMM analyses indicated a good fit of the model to the data. CONCLUSIONS: The ATTOGEN instrument proved to be a reliable and valid tool, suitable for assessing students' knowledge and attitudes towards generic medicines.

AB - BACKGROUND: Many patients with cancer or other systemic illnesses can experience malnutrition. One way to mitigate malnutrition is by insertion of a percutaneous endoscopic gastrostomy feeding tube (PEG tube). The goal of this retrospective matched cohort study is to evaluate if PEG tube placement improved nutritional status and overall survival (OS) in advanced gastroesophageal (GE) cancer patients who are undergoing anti-neoplastic therapy. METHODS: GE cancer patients who were treated and evaluated by a nutritionist and had at least 2 nutritionist follow-up visits were identified. Patients with PEG tube were matched to patients that did not undergo PEG placement (non-PEG). Clinical characteristics, GE symptoms reported at nutrition follow-up visits, and OS were recorded. RESULTS: 20 PEG and 18 non-PEG cases met criteria for further analyses. After correction for multiple testing, there were no OS differences between PEG and non-PEG, treatment naive and previously treated. However, PEG esophageal carcinoma has statistically significant inferior OS compared with non-PEG esophageal carcinoma. PEG placement did not significantly reduce the proportion of patients with weight loss between the initial nutrition assessment and 12-week follow-up. CONCLUSIONS: In this small study, PEG placement had inferior OS outcome for GE esophageal carcinoma, no improvement in OS for other evaluated groups, and did not reduce weight loss between baseline and 12-week follow-up. Unless there is prospective randomized trial that can show superiority of PEG placement in this population, PEG placement in this group cannot be endorsed.

AB - This research investigates the influence of place of residence and diabetic patient's socioeconomic position on their use of health services in a universal health care system. This retrospective cross-sectional population-based study is based on the joint use of the Health Insurance information systems, an ecological indicator of social deprivation and an indicator of potential spatial accessibility of healthcare provision in the Midi-Pyrenees region. Using French healthcare insurance population-based data on reimbursement of out-of-hospital care during the year 2012, we study the use of health services among patients aged 50 and over (n = 90,136).We built logistic regression models linking health services use to socioeconomic position by geographic area, adjusted for age, gender, healthcare provision, information regarding patients precariousness, and long-term condition, used as proxy for the state of health. After adjustment for healthcare provision, the lower population density in the geographical area of concern, the lower the access to specialised care, independent of the patients' SEP. General practitioner attendance was higher among the patients with the lowest SEP without being clearly influenced by their living place. We found no clear influence of either patients' SEP or their living place on their access to biological follow-up. This study is an attempt to account for the geographical context and to go further in studying the social determinants of health among diabetes patients.

AB - Research on distributed task planning model for multi-autonomous underwater vehicle (MAUV). A scroll time domain quantum artificial bee colony (STDQABC) optimization algorithm is proposed to solve the multi-AUV optimal task planning scheme. In the uncertain marine environment, the rolling time domain control technique is used to realize a numerical optimization in a narrowed time range. Rolling time domain control is one of the better task planning techniques, which can greatly reduce the computational workload and realize the tradeoff between AUV dynamics, environment and cost. Finally, a simulation experiment was performed to evaluate the distributed task planning performance of the scroll time domain quantum bee colony optimization algorithm. The simulation results demonstrate that the STDQABC algorithm converges faster than the QABC and ABC algorithms in terms of both iterations and running time. The STDQABC algorithm can effectively improve MAUV distributed tasking planning performance, complete the task goal and get the approximate optimal solution. PMID- 29186167 TI - Deployment-based lifetime optimization for linear wireless sensor networks considering both retransmission and discrete power control. AB - A sophisticated method for node deployment can efficiently reduce the energy consumption of a Wireless Sensor Network (WSN) and prolong the corresponding network lifetime. Pioneers have proposed many node deployment based lifetime optimization methods for WSNs, however, the retransmission mechanism and the discrete power control strategy, which are widely used in practice and have large effect on the network energy consumption, are often neglected and assumed as a continuous one, respectively, in the previous studies. In this paper, both retransmission and discrete power control are considered together, and a more realistic energy-consumption-based network lifetime model for linear WSNs is provided. Using this model, we then propose a generic deployment-based optimization model that maximizes network lifetime under coverage, connectivity and transmission rate success constraints. The more accurate lifetime evaluation conduces to a longer optimal network lifetime in the realistic situation. To illustrate the effectiveness of our method, both one-tiered and two-tiered uniformly and non-uniformly distributed linear WSNs are optimized in our case studies, and the comparisons between our optimal results and those based on relatively inaccurate lifetime evaluation show the advantage of our method when investigating WSN lifetime optimization problems. PMID- 29186168 TI - Quantitative evaluation of age-related decline in control of preprogramed movement. AB - In this paper, we examined the age-related changes in control of preprogramed movement, with emphasis on its accuracy. Forty-nine healthy subjects participated in this study, and were divided into three groups depending on their ages: the young group (20-39 years) (n = 16), the middle-age group (40-59 years) (n = 16), and the elderly group (60-79 years) (n = 17). We asked the subjects to perform step-tracking movements of the wrist joint with a manipulandum, and recorded the movements. We evaluated the accuracy of control of preprogramed movement in the three groups in terms of the primary submovement, which was identified as the first segment of the step-tracking movement based on the bell-shaped velocity profile, and calculated the distance between the end position of the primary submovement and the target (i.e. error). The error in the young group was found to be significantly smaller than that in the middle-age and elderly groups, i.e., the error was larger for the higher age groups. These results suggest that young subjects have better control of preprogramed movement than middle-age or elderly subjects. Finally, we examined the temporal property of the primary submovement and its age-related changes. The duration of the primary submovement tended to be longer for the aged groups, although significance was reached only for the elderly group. In particular, the ratio of the duration of the primary submovement to total movement time tended to be lower for the aged groups, suggesting that the proportion of additional movements that are required to compensate for the incomplete control in the preprogramed movement, which are under feedback control, was higher for the aged groups. Consequently, our results indicate that the distance between the end point of the primary submovement and the target center (i.e. error) in the step-tracking movement is a useful parameter to evaluate the age-related changes in control of preprogramed movement. PMID- 29186169 TI - Epidemiology of severe mental illness in Hunan province in central China during 2014-2015: A multistage cross-sectional study. AB - OBJECTIVE: Severe mental illness (SMI) represents major social and public health problem in China, especially in low- or middle-income regions. We aim to assess the prevalence and distribution of SMI in Hunan province in central China. METHODS: Multistage stratified random sampling methods were used to select qualified subjects in 123 districts and counties in Hunan province. 89465 individuals were randomly identified, and 72999 (81.6%) completed the supplemental 12-Item General Health Questionnaire (GHQ-12) and Cue questionnaire of psychiatric abnormal behaviors. 6082 suspected individuals having high or moderate risk, or psychiatric cues, were administered the Structured Clinical Interview for DSM-IV Axis I disorders (SCID-I) by psychiatrists. RESULTS: 720 respondents were definitely diagnosed as SMI. The 1-month and lifetime prevalence was 9.350/00 and 10.100/00, respectively. The most frequent SMI was schizophrenia, followed by bipolar disorder, intellectual disability, epileptic mental disorder, paranoid psychosis and schizoaffective disorders, with 1-month prevalence ranging from 0.110/00 to 6.500/00 and lifetime prevalence ranging from 0.240/00 to 6.860/00. Multivariate logistic regression analysis revealed that lower education, farmer occupation, retirees or jobless/unemployed, unmarried or divorced and age of 30-64 years old were major factors that associated with the increased risk of SMI. In addition, only 33.3% of 528 patients who completed questionnaire sought help in psychiatric institutions, and up to 51.7% of 720 patients were not referred to the SMI management system in Hunan province. CONCLUSIONS: These findings provided a large-scale prevalence data of SMI in a provincial sample of China. The psychiatric disorders brought economical and psychological burden for family and society, which may shed light on the significance of scaling up province-wide mental health service and strengthening the SMI management. PMID- 29186171 TI - Analyzing cross-college course enrollments via contextual graph mining. AB - The ability to predict what courses a student may enroll in the coming semester plays a pivotal role in the allocation of learning resources, which is a hot topic in the domain of educational data mining. In this study, we propose an innovative approach to characterize students' cross-college course enrollments by leveraging a novel contextual graph. Specifically, different kinds of variables, such as students, courses, colleges and diplomas, as well as various types of variable relations, are utilized to depict the context of each variable, and then a representation learning algorithm node2vec is applied to extracting sophisticated graph-based features for the enrollment analysis. In this manner, the relations between any pair of variables can be measured quantitatively, which enables the variable type to transform from nominal to ratio. These graph-based features are examined by the random forest algorithm, and experiments on 24,663 students, 1,674 courses and 417,590 enrollment records demonstrate that the contextual graph can successfully improve analyzing the cross-college course enrollments, where three of the graph-based features have significantly stronger impacts on prediction accuracy than the others. Besides, the empirical results also indicate that the student's course preference is the most important factor in predicting future course enrollments, which is consistent to the previous studies that acknowledge the course interest is a key point for course recommendations. PMID- 29186170 TI - Evaluating the versatility of EEG models generated from motor imagery tasks: An exploratory investigation on upper-limb elbow-centered motor imagery tasks. AB - Electroencephalography (EEG) has recently been considered for use in rehabilitation of people with motor deficits. EEG data from the motor imagery of different body movements have been used, for instance, as an EEG-based control method to send commands to rehabilitation devices that assist people to perform a variety of different motor tasks. However, it is both time and effort consuming to go through data collection and model training for every rehabilitation task. In this paper, we investigate the possibility of using an EEG model from one type of motor imagery (e.g.: elbow extension and flexion) to classify EEG from other types of motor imagery activities (e.g.: open a drawer). In order to study the problem, we focused on the elbow joint. Specifically, nine kinesthetic motor imagery tasks involving the elbow were investigated in twelve healthy individuals who participated in the study. While results reported that models from goal oriented motor imagery tasks had higher accuracy than models from the simple joint tasks in intra-task testing (e.g., model from elbow extension and flexion task was tested on EEG data collected from elbow extension and flexion task), models from simple joint tasks had higher accuracies than the others in inter task testing (e.g., model from elbow extension and flexion task tested on EEG data collected from drawer opening task). Simple single joint motor imagery tasks could, therefore, be considered for training models to potentially reduce the number of repetitive data acquisitions and model training in rehabilitation applications. PMID- 29186172 TI - Geometric calibration of a stationary digital breast tomosynthesis system based on distributed carbon nanotube X-ray source arrays. AB - Stationary digital breast tomosynthesis (sDBT) with distributed X-ray sources based on carbon nanotube (CNT) field emission cathodes has been recently proposed as an approach that can prevent motion blur produced by traditional DBT systems. In this paper, we simulate a geometric calibration method based on a proposed multi-source CNT X-ray sDBT system. This method is a projection matrix-based approach with seven geometric parameters, all of which can be obtained from only one projection datum of the phantom. To our knowledge, this study reports the first application of this approach in a CNT-based multi-beam X-ray sDBT system. The simulation results showed that the extracted geometric parameters from the calculated projection matrix are extremely close to the input values and that the proposed method is effective and reliable for a square sDBT system. In addition, a traditional cone-beam computed tomography (CT) system was also simulated, and the uncalibrated and calibrated geometric parameters were used in image reconstruction based on the filtered back-projection (FBP) method. The results indicated that the images reconstructed with calibrated geometric parameters have fewer artifacts and are closer to the reference image. All the simulation tests showed that this geometric calibration method is optimized for sDBT systems but can also be applied to other application-specific CT imaging systems. PMID- 29186173 TI - Reference-shaping adaptive control by using gradient descent optimizers. AB - This study presents a model reference adaptive control scheme based on reference shaping approach. The proposed adaptive control structure includes two optimizer processes that perform gradient descent optimization. The first process is the control optimizer that generates appropriate control signal for tracking of the controlled system output to a reference model output. The second process is the adaptation optimizer that performs for estimation of a time-varying adaptation gain, and it contributes to improvement of control signal generation. Numerical update equations derived for adaptation gain and control signal perform gradient descent optimization in order to decrease the model mismatch errors. To reduce noise sensitivity of the system, a dead zone rule is applied to the adaptation process. Simulation examples show the performance of the proposed Reference Shaping Adaptive Control (RSAC) method for several test scenarios. An experimental study demonstrates application of method for rotor control. PMID- 29186174 TI - Parallel arrangements of positive feedback loops limit cell-to-cell variability in differentiation. AB - Cellular differentiations are often regulated by bistable switches resulting from specific arrangements of multiple positive feedback loops (PFL) fused to one another. Although bistability generates digital responses at the cellular level, stochasticity in chemical reactions causes population heterogeneity in terms of its differentiated states. We hypothesized that the specific arrangements of PFLs may have evolved to minimize the cellular heterogeneity in differentiation. In order to test this we investigated variability in cellular differentiation controlled either by parallel or serial arrangements of multiple PFLs having similar average properties under extrinsic and intrinsic noises. We find that motifs with PFLs fused in parallel to one another around a central regulator are less susceptible to noise as compared to the motifs with PFLs arranged serially. Our calculations suggest that the increased resistance to noise in parallel motifs originate from the less sensitivity of bifurcation points to the extrinsic noise. Whereas estimation of mean residence times indicate that stable branches of bifurcations are robust to intrinsic noise in parallel motifs as compared to serial motifs. Model conclusions are consistent both in AND- and OR-gate input signal configurations and also with two different modeling strategies. Our investigations provide some insight into recent findings that differentiation of preadipocyte to mature adipocyte is controlled by network of parallel PFLs.

AB - Although the importance of vocabulary training in English speaking countries is well recognized and has been extensively studied, the same is not true for Spanish-few evidence based vocabulary studies for Spanish-speaking children have been reported. Here, two rich oral vocabulary training programs (definition and context), based on literature about vocabulary instruction for English-speaking children, were developed and applied in a sample of 100 Spanish elementary school third-graders recruited from areas of predominantly low socio-economic status (SES). Compared to an alternative read-aloud method which served as the control, both explicit methods were more effective in teaching word meanings when assessed immediately after the intervention. Nevertheless, five months later, only the definition group continued to demonstrate significant vocabulary knowledge gains. The definition method was more effective in specifically teaching children word meanings and, more broadly, in helping children organize and express knowledge of words. We recommend the explicit and rich vocabulary instruction as a means to fostering vocabulary knowledge in low SES children. PMID- 29186176 TI - Analysis of DNA topology of EBV minichromosomes in HEK 293 cells. AB - Simian Virus 40 (SV40) and Epstein-Barr Virus (EBV) are frequently used as model systems to study DNA replication. Their genomes are both circular duplex DNAs organized in a single replicon where replication initiates at a precise site upon binding of a specific protein: the large tumor (T) antigen for SV40 and the Epstein-Barr Nuclear Antigen 1 (EBNA-1) for EBV. Despite the abundant information available on the genetics and biochemistry of the replication process in these systems, little is known about the changes in DNA topology that take place as molecules are transfected into eukaryotic cells, assembled into chromatin and bind initiator proteins to start replication. Here we used high-resolution two dimensional agarose gel electrophoresis to demonstrate that in Human Embryonic Kidney (HEK) 293 cells, minichromosomes of almost the same mass carrying either the SV40 or the EBV replication origin showed similar topological features. The patterns were very similar regardless of the initiator proteins. We also showed that in a hybrid minichromosome, pEco3'Delta, that initiates replication from the SV40 origin, the presence of EBNA-1 and its putative binding to the EBV "family of repeats" induces no significant topological change. These observations challenge the idea that binding of EBNA-1 to oriP could induce negative supercoiling and favor a model suggesting that it binds to oriP in a two-step process where only the second step causes structural changes in a transient cell cycle specific manner. PMID- 29186177 TI - Intensive Care Syndrome: Promoting Independence and Return to Employment (InS:PIRE). Early evaluation of a complex intervention. AB - BACKGROUND: Many patients suffer significant physical, social and psychological problems in the months and years following critical care discharge. At present, there is minimal evidence of any effective interventions to support this patient group following hospital discharge. The aim of this project was to understand the impact of a complex intervention for ICU survivors. METHODS: Quality improvement project conducted between September 2014 and June 2016, enrolling 49 selected patients from one ICU in Scotland. To evaluate the impact of this programme outcomes were compared to an existing cohort of patients from the same ICU from 2008-2009. Patients attended a five week peer supported rehabilitation programme. This multidisciplinary programme included pharmacy, physiotherapy, nursing, medical, and psychology input. The primary outcome in this evaluation was the EQ 5D, a validated measure of health-related quality of life. The minimally clinically important difference (MCID) in the EQ-5D is 0.08. We also measured change in self-efficacy over the programme duration. Based on previous research, this study utilised a 2.4 (6%) point change in self-efficacy scores as a MCID. RESULTS: 40 patients (82%) completed follow-up surveys at 12 months. After regression adjustment for those factors known to impact recovery from critical care, there was a 0.07-0.16 point improvement in quality of life for those patients who took part in the intervention compared to historical controls from the same institution, depending on specific regression strategy used. Self efficacy scores increased by 2.5 points (6.25%) over the duration of the five week programme (p = 0.003), and was sustained at one year post intervention. In the year following ICU, 15 InS:PIRE patients returned to employment or volunteering roles (88%) compared with 11 (46%) in the historical control group (p = 0.15). CONCLUSIONS AND RELEVANCE: This historical control study suggests that a complex intervention may improve quality of life and self-efficacy in survivors of ICU. A larger, multi-centre study is needed to investigate this intervention further. PMID- 29186178 TI - Masticatory jaw movement of Exaeretodon argentinus (Therapsida: Cynodontia) inferred from its dental microwear. AB - Dental microwear of four postcanine teeth of Exaeretodon argentinus was analyzed using both two dimensional (2D) and three dimensional (3D) methods to infer their masticatory jaw movements. Results of both methods were congruent, showing that linear microwear features (scratches) were well aligned and mostly directed to the antero-posterior direction in all four teeth examined. These findings support the palinal masticatory jaw movement, which was inferred in previous studies based on the observation of gross morphology of wear facets. In contrast, the lack of detection of lateral scratches confirmed the absence of the lateral jaw movement that was also proposed by a previous study. Considering previous microwear studies on cynodonts, palinal jaw movements observed in Exaeretodon evolved within cynognathian cynodonts from the fully orthal jaw movement of its basal member. Although there are currently only three studies of dental microwear of non-mammalian cynodonts including the present study, microwear analysis is a useful tool for the reconstruction of masticatory jaw movement and its future application to various cynodonts will shed light on the evolutionary process of jaw movement towards the mammalian condition in more detail. PMID- 29186179 TI - Nonword repetition in adults who stutter: The effects of stimuli stress and auditory-orthographic cues. AB - PURPOSE: Adults who stutter (AWS) are less accurate in their immediate repetition of novel phonological sequences compared to adults who do not stutter (AWNS). The present study examined whether manipulation of the following two aspects of traditional nonword repetition tasks unmask distinct weaknesses in phonological working memory in AWS: (1) presentation of stimuli with less-frequent stress patterns, and (2) removal of auditory-orthographic cues immediately prior to response. METHOD: Fifty-two participants (26 AWS, 26 AWNS) produced 12 bisyllabic nonwords in the presence of corresponding auditory-orthographic cues (i.e., immediate repetition task), and the absence of auditory-orthographic cues (i.e., short-term recall task). Half of each cohort (13 AWS, 13 AWNS) were exposed to the stimuli with high-frequency trochaic stress, and half (13 AWS, 13 AWNS) were exposed to identical stimuli with lower-frequency iambic stress. RESULTS: No differences in immediate repetition accuracy for trochaic or iambic nonwords were observed for either group. However, AWS were less accurate when recalling iambic nonwords than trochaic nonwords in the absence of auditory-orthographic cues. CONCLUSIONS: Manipulation of two factors which may minimize phonological demand during standard nonword repetition tasks increased the number of errors in AWS compared to AWNS. These findings suggest greater vulnerability in phonological working memory in AWS, even when producing nonwords as short as two syllables. PMID- 29186180 TI - Clonogenic, myogenic progenitors expressing MCAM/CD146 are incorporated as adventitial reticular cells in the microvascular compartment of human post-natal skeletal muscle. AB - Recent observation identifies subendothelial (mural) cells expressing MCAM, a specific system of clonogenic, self-renewing, osteoprogenitors (a.k.a, "mesenchymal stem cells") in the microvascular compartment of post-natal human bone marrow (BM). In this study, we used MCAM/CD146, as a marker to localize, isolate and assay subendothelial clonogenic cells from the microvasculature of postnatal human skeletal muscle. We show here that these cells share with their BM counterpart, anatomic position (subendothelial/adventitial) and ex vivo clonogenicity (CFU-Fs). When assayed under the stringent conditions, these cells display a high spontaneous myogenic potential (independent of co-culture with myoblasts or of in vivo fusion with local myoblasts), which is otherwise only attained in cultures of satellite cells. These muscle-derived mural cells activated a myogenic program in culture. Cultured CD146+ cells expressed the myogenic factors (Pax7, Pax3 and Myf5), NCAM/CD56, desmin as well as proteins characteristic of more advanced myogenic differentiation, such as myosin heavy chain. In vivo, these cells spontaneously generate myotubes and myofibrils. These data identify the anatomy and phenotype of a novel class of committed myogenic progenitor in human post-natal skeletal muscle of subendothelial cells associated with the abluminal surface of microvascular compartment distinct from satellite cells. PMID- 29186181 TI - Development of a homogenous high-throughput assay for inositol hexakisphosphate kinase 1 activity. AB - Inositol pyrophosphates have been implicated in a wide range of cellular processes. Inositol hexakisphosphate kinase 1 catalyzes the pyrophosphorylation of inositol hexakisphosphate into inositol 5-diphospho-1,2,3,4,6 pentakisphosphate which is important in numerous areas of cell physiology such as DNA repair and glucose homeostasis. Furthermore, inositol 5-diphospho-1,2,3,4,6 pentakisphosphate is implicated in the pathology of diabetes and other human diseases. As such there is a demonstrated need in the field for a robust chemical probe to better understand the role of inositol hexakisphosphate kinase 1 and inositol pyrophosphate in physiology and disease. To aid in this effort we developed a homogenous coupled bioluminescence assay for measuring inositol hexakisphosphate kinase 1 activity in a 384-well format (Z' = 0.62+/-0.05). Using this assay we were able to confirm the activity of a known inositol hexakisphosphate kinase 1 inhibitor N2-(m-trifluorobenzyl), N6-(p nitrobenzyl)purine. We also screened the Sigma library of pharmacologically active compounds at 10MUM concentration and found 24 hits. Two of the most potent compounds were found to have an IC50 less than 5MUM. The use of this high throughput assay will accelerate the field towards the discovery of a potent inositol hexakisphosphate kinase 1 inhibitor. PMID- 29186182 TI - Identification of a novel linear B-cell epitope in nonstructural protein 11 of porcine reproductive and respiratory syndrome virus that are conserved in both genotypes. AB - Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most economically important pathogens, that hinder the development of global pork industry. Its nonstructural protein 11 (nsp11), with the nidoviral uridylate specific endoribonuclease (NendoU) domain, is essential for PRRSV genome replication and it also contributes to host innate immunity suppression. However, the immunogenicity and immune structure of PRRSV nsp11 have not been well investigated yet. In this study, a monoclonal antibody (mAb), designated 3F9, that against nsp11 was generated. Subsequently, a series of partially overlapped fragments, covered the nsp1140-223aa, were expressed to test the reactivity with mAb 3F9, and the 111DCREY115 was found to be the core unit of the B-cell epitope recognized by mAb 3F9. Further investigation indicated that both genotype 1 and genotype 2 PRRSV can be recognized by mAb 3F9, due to the 111DCREY115 is conserved in both genotype virus. Meanwhile, this epitope, localized at the surface of nsp11 in 3D structure, is confirmed to be able to induce humoral immune response in PRRSV infected pigs. These findings do not only provide an mAb tool to further investigate the function of nsp11, they also indicate the diagnostic potential for this epitope. PMID- 29186183 TI - A tool for simulating collision probabilities of animals with marine renewable energy devices. AB - The mathematical problem of establishing a collision probability distribution is often not trivial. The shape and motion of the animal as well as of the the device must be evaluated in a four-dimensional space (3D motion over time). Earlier work on wind and tidal turbines was limited to a simplified two dimensional representation, which cannot be applied to many new structures. We present a numerical algorithm to obtain such probability distributions using transient, three-dimensional numerical simulations. The method is demonstrated using a sub-surface tidal kite as an example. Necessary pre- and post-processing of the data created by the model is explained, numerical details and potential issues and limitations in the application of resulting probability distributions are highlighted. PMID- 29186184 TI - Considerations on Visible Light Communication security by applying the Risk Matrix methodology for risk assessment. AB - Visible Light Communications (VLC) is a cutting edge technology for data communication that is being considered to be implemented in a wide range of applications such as Inter-vehicle communication or Local Area Network (LAN) communication. As a novel technology, some aspects of the implementation of VLC have not been deeply considered or tested. Among these aspects, security and its implementation may become an obstacle for VLCs broad usage. In this article, we have used the well-known Risk Matrix methodology to determine the relative risk that several common attacks have in a VLC network. Four examples: a War Driving, a Queensland alike Denial of Service, a Preshared Key Cracking, and an Evil Twin attack, illustrate the utilization of the methodology over a VLC implementation. The used attacks also covered the different areas delimited by the attack taxonomy used in this work. By defining and determining which attacks present a greater risk, the results of this work provide a lead into which areas should be invested to increase the safety of VLC networks. PMID- 29186185 TI - Cost-effectiveness of different strategies for diagnosis of uncomplicated urinary tract infections in women presenting in primary care. AB - BACKGROUND: Uncomplicated Urinary Tract Infections (UTIs) are common in primary care resulting in substantial costs. Since antimicrobial resistance against antibiotics for UTIs is rising, accurate diagnosis is needed in settings with low rates of multidrug-resistant bacteria. OBJECTIVE: To compare the cost effectiveness of different strategies to diagnose UTIs in women who contacted their general practitioner (GP) with painful and/or frequent micturition between 2006 and 2008 in and around Amsterdam, The Netherlands. METHODS: This is a model based cost-effectiveness analysis using data from 196 women who underwent four tests: history, urine stick, sediment, dipslide, and the gold standard, a urine culture. Decision trees were constructed reflecting 15 diagnostic strategies comprising different parallel and sequential combinations of the four tests. Using the decision trees, for each strategy the costs and the proportion of women with a correct positive or negative diagnosis were estimated. Probabilistic sensitivity analysis was used to estimate uncertainty surrounding costs and effects. Uncertainty was presented using cost-effectiveness planes and acceptability curves. RESULTS: Most sequential testing strategies resulted in higher proportions of correctly classified women and lower costs than parallel testing strategies. For different willingness to pay thresholds, the most cost effective strategies were: 1) performing a dipstick after a positive history for thresholds below ?10 per additional correctly classified patient, 2) performing both a history and dipstick for thresholds between ?10 and ?17 per additional correctly classified patient, 3) performing a dipstick if history was negative, followed by a sediment if the dipstick was negative for thresholds between ?17 and ?118 per additional correctly classified patient, 4) performing a dipstick if history was negative, followed by a dipslide if the dipstick was negative for thresholds above ?118 per additional correctly classified patient. CONCLUSION: Depending on decision makers' willingness to pay for one additional correctly classified woman, the strategy consisting of performing a history and dipstick simultaneously (ceiling ratios between ?10 and ?17) or performing a sediment if history and subsequent dipstick are negative (ceiling ratios between ?17 and ?118) are the most cost-effective strategies to diagnose a UTI.

PMID- 29186186 TI - Application of non-invasive low strength pulsed electric field to EGCG treatment synergistically enhanced the inhibition effect on PANC-1 cells. AB - Traditional therapies for pancreatic cancer are usually expensive and likely to cause side effects, and most patients have the risk of recurrence and suffering pain. Here, we investigated combination treatment of epigallocatechin-3-gallate (EGCG) and non-invasive low strength pulsed electric field (PEF) on the human pancreatic cell line PANC-1. Cells were cultured in various concentrations of EGCG and exposed to trains of PEF. The results showed that the low strength PEF alone or single treatment with low concentration of EGCG did not obviously affect the cell proliferation and migration in PANC-1. However, the EGCG-induced inhibitions of cell viability and migration ability in PANC-1 were dramatically enhanced by the further exposure of low strength PEF (60 V/cm). In particular, the same combination treatment caused less inhibition of cell viability in non malignant HEK293 cells. We also found the combination treatment significantly decreased the ratio of Bcl-2/Bax protein and increased caspase activity in PANC-1 cells, resulting in the promotion of apoptotic responses, evidenced by chromatin condensation. The findings of the present study reveal the synergistic reactions in the combination treatment may severely disturb mitochondria, enhance the intrinsic pathway transduction, and effectively induce apoptosis; moreover, the migration and invasion of PANC-1 cancer cells were also significantly suppressed. Since normal cells are less sensitive to this combination treatment, and the non invasive PEF could be modified to focus on a specific location, this treatment may serve as a promising method for anti-cancer therapy.

AB - Previous studies have shown modulation of corticospinal output of the agonist muscle when a known-movement is prepared but withheld until a response signal appearance, reflecting motor preparation processes. However, modulation in the antagonist muscles has not been described, despite the fact that reaching movements require precise coordination between the activation of agonist and antagonist muscles. In this study, participants performed an instructed-delay reaction time (RT) task, with randomized elbow flexion and extension movements. The aim was to assess the time course modulation of corticospinal output in two antagonist muscles, by simultaneously quantified the amplitude of motor evoked potentials (MEPs) in biceps brachii and triceps brachii, and the amplitude and direction of elbow movements evoked by transcranial magnetic stimulation (TMS). Depending on the prepared movement direction, a specific modulation of corticospinal output was observed, MEPs and TMS-evoked movements amplitude being relatively greater for extension compared to flexion. At the end of motor preparation, a decrease in MEPs amplitude was observed for both biceps brachii and triceps brachii, regardless of the prepared movement direction. In contrast, the probability of evoking movement in the flexion direction and the amplitude of TMS-evoked movement decreased at the end of preparation for flexion, but not for extension. Together, these results confirm the existence of inhibitory processes at the end of the motor preparation, probably to avoid a premature motor response. Moreover, they provide evidence of differences in the corticospinal control of elbow flexor and extensor muscles with patterns of modulation that are not necessarily reciprocal during motor preparation.

AB - Introduction of and invasion by alien plant pathogens represents the main cause of emerging infectious diseases affecting domesticated and wild plant species worldwide. The trade in living plants is the most common pathway of introduction. Many of the alien tree pathogens recently introduced into Europe were not previously included on any quarantine lists. To help determine the potential risk of pest introduction through trading of ornamental plants, a sentinel nursery was established in Beijing, China in 2008. The sentinel nursery planting included four of the most common ornamental woody species shipped to Europe including Ilex cornuta var. fortunae, Zelkova schneideriana, Fraxinus chinensis and Buxus microphylla. Symptoms developing on these species within the sentinel nursery were detected in 2013 and consisted of necrotic spots on leaves, canker and stem necrosis, shoot blight and shoot necrosis. Fungi associated with the trees and their symptoms included Alternaria alternata detected from all hosts; Diaporthe liquidambaris and Diaporthe capsici from bark and leaf necrosis of Zelkova schneideriana; Botryosphaeria dothidea and Nothophoma quercina from stem cankers on Fraxinus chinensis and leaf necrosis on Ilex cornuta; and Pseudonectria foliicola from leaf necrosis on Buxus microphylla. Next generation sequencing analysis from asymptomatic tissues detected eighteen OTU's at species level among which some taxa had not been previously recorded in Europe. These results clearly demonstrate that looking at trees of internationally traded species in the region of origin can reveal the presence of potentially harmful organisms of major forestry, landscape or crop trees. Results of this study also provide an indication as to how some disease agents can be introduced using pathways other than the co-generic hosts. Hence, sentinel nurseries represent one potential mechanism to address the current lack of knowledge about pests in the countries from where live plants are shipped and the threats they represent to native flora and crops in importing countries. PMID- 29186188 TI - Effect of age on chronic inflammation and responsiveness to bacterial and viral challenges. AB - To identify reliable biomarkers of age-related changes in chronic inflammation and responsiveness to bacterial and viral challenges, we evaluated endogenous and ex vivo stimulated levels of 18 inflammatory markers, using whole blood collected in EDTA and sodium heparin tubes from 41 healthy volunteers, i.e., 11 men + 10 women aged 20-35 and 10 men + 10 women aged 50-77. These studies revealed significant differences in the levels of inflammatory markers when blood was collected in EDTA versus sodium heparin and age related differences in these biomarkers were confirmed with blood collected in EDTA from 120 healthy volunteers in 3 age categories, ie, 20 men + 20 women, aged 20-35, 36-49 and 50 77. Studies with unstimulated blood samples, to measure levels of chronic inflammation, revealed a significant increase with age in IL-12p70, CRP and PGE2, consistent with the concept of "inflammaging", and a decrease in G-CSF in both men and women. Interestingly, in response to E. coli stimulation, PGE2 levels were markedly reduced in the 50-77 year old cohort while they were increased following Herpes Simplex virus-1 (HSV-1) stimulation, along with IL-8. In addition, unlike E. coli, HSV-1 potently stimulated IFNalpha production, but levels were dramatically reduced in the older cohort, consistent with a reduced ability to generate an anti-viral response. We also found platelets and CD8+ T cells were reduced with age while CD4+ T cells were significantly increased, resulting in a substantially higher CD4/CD8 ratio in the older cohort. Surprisingly, however, we found that the older cohort exhibited more T cell proliferation and IFNgamma production in response to anti-CD3+anti-CD28 stimulation. Importantly, there was considerable person-to-person variation in these inflammatory markers in all age groups, making possible comparisons between a person's "inflammage" and chronological age. These assays should help to identify individuals at high risk of autoimmune disorders and cancer. PMID- 29186192 TI - Development of a GAL4-VP16/UAS trans-activation system for tissue specific expression in Medicago truncatula. AB - Promoters with tissue-specific activity are very useful to address cell autonomous and non cell autonomous functions of candidate genes. Although this strategy is widely used in Arabidopsis thaliana, its use to study tissue-specific regulation of root symbiotic interactions in legumes has only started recently. Moreover, using tissue specific promoter activity to drive a GAL4-VP16 chimeric transcription factor that can bind short upstream activation sequences (UAS) is an efficient way to target and enhance the expression of any gene of interest. Here, we developed a collection of promoters with different root cell layers specific activities in Medicago truncatula and tested their abilities to drive the expression of a chimeric GAL4-VP16 transcription factor in a trans-activation UAS: beta-Glucuronidase (GUS) reporter gene system. By developing a binary vector devoted to modular Golden Gate cloning together with a collection of adapted tissue specific promoters and coding sequences we could test the activity of four of these promoters in trans-activation GAL4/UAS systems and compare them to "classical" promoter GUS fusions. Roots showing high levels of tissue specific expression of the GUS activity could be obtained with this trans-activation system. We therefore provide the legume community with new tools for efficient modular Golden Gate cloning, tissue specific expression and a trans-activation system. This study provides the ground work for future development of stable transgenic lines in Medicago truncatula. PMID- 29186191 TI - Lipopolysaccharide structure impacts the entry kinetics of bacterial outer membrane vesicles into host cells. AB - Outer membrane vesicles are nano-sized microvesicles shed from the outer membrane of Gram-negative bacteria and play important roles in immune priming and disease pathogenesis. However, our current mechanistic understanding of vesicle-host cell interactions is limited by a lack of methods to study the rapid kinetics of vesicle entry and cargo delivery to host cells. Here, we describe a highly sensitive method to study the kinetics of vesicle entry into host cells in real time using a genetically encoded, vesicle-targeted probe. We found that the route of vesicular uptake, and thus entry kinetics and efficiency, are shaped by bacterial cell wall composition. The presence of lipopolysaccharide O antigen enables vesicles to bypass clathrin-mediated endocytosis, which enhances both their entry rate and efficiency into host cells. Collectively, our findings highlight the composition of the bacterial cell wall as a major determinant of secretion-independent delivery of virulence factors during Gram-negative infections. PMID- 29186193 TI - RIG-I-like receptor activation by dengue virus drives follicular T helper cell formation and antibody production. AB - Follicular T helper cells (TFH) are fundamental in orchestrating effective antibody-mediated responses critical for immunity against viral infections and effective vaccines. However, it is unclear how virus infection leads to TFH induction. We here show that dengue virus (DENV) infection of human dendritic cells (DCs) drives TFH formation via crosstalk of RIG-I-like receptor (RLR) RIG-I and MDA5 with type I Interferon (IFN) signaling. DENV infection leads to RLR dependent IKKepsilon activation, which phosphorylates IFNalpha/beta receptor induced STAT1 to drive IL-27 production via the transcriptional complex ISGF3. Inhibiting RLR activation as well as neutralizing antibodies against IL-27 prevented TFH formation. DENV-induced CXCR5+PD-1+Bcl-6+ TFH cells secreted IL-21 and activated B cells to produce IgM and IgG. Notably, RLR activation by synthetic ligands also induced IL-27 secretion and TFH polarization. These results identify an innate mechanism by which antibodies develop during viral disease and identify RLR ligands as potent adjuvants for TFH-promoting vaccination strategies. PMID- 29186195 TI - Assemblies of amyloid-beta30-36 hexamer and its G33V/L34T mutants by replica exchange molecular dynamics simulation. AB - The aggregation of amyloid-beta peptides is associated with the pathogenesis of Alzheimer's disease, in which the 30-36 fragments play an important part as a fiber-forming hydrophobic region. The fibrillar structure of Abeta30-36 has been detected by means of X-ray diffraction, but its oligomeric structural determination, biophysical characterization, and pathological mechanism remain elusive. In this study, we have investigated the structures of Abeta30-36 hexamer as well as its G33V and L34T mutants in explicit water environment using replica exchange molecular dynamics (REMD) simulations. Our results show that the wild type (WT) Abeta30-36 hexamer has a preference to form beta-barrel and bilayer beta-sheet conformations, while the G33V or L34T mutation disrupts the beta barrel structures: the G33V mutant is homogenized to adopt beta-sheet-rich bilayers, and the structures of L34T mutant on the contrary get more diverse. The hydrophobic interaction plays a critical role in the formation and stability of oligomeric assemblies among all the three systems. In addition, the substitution of G33 by V reduces the beta-sheet content in the most populated conformations of Abeta30-36 oligomers through a steric effect. The L34T mutation disturbs the interpeptide hydrogen bonding network, and results in the increased coil content and morphological diversity. Our REMD runs provide structural details of WT and G33V/L34T mutant Abeta30-36 oligomers, and molecular insight into the aggregation mechanism, which will be helpful for designing novel inhibitors or amyloid-based materials. PMID- 29186194 TI - Human T-cell leukemia virus type 1 infects multiple lineage hematopoietic cells in vivo. AB - Human T-cell leukemia virus type 1 (HTLV-1) infects mainly CD4+CCR4+ effector/memory T cells in vivo. However, it remains unknown whether HTLV-1 preferentially infects these T cells or this virus converts infected precursor cells to specialized T cells. Expression of viral genes in vivo is critical to study viral replication and proliferation of infected cells. Therefore, we first analyzed viral gene expression in non-human primates naturally infected with simian T-cell leukemia virus type 1 (STLV-1), whose virological attributes closely resemble those of HTLV-1. Although the tax transcript was detected only in certain tissues, Tax expression was much higher in the bone marrow, indicating the possibility of de novo infection. Furthermore, Tax expression of non-T cells was suspected in bone marrow. These data suggest that HTLV-1 infects hematopoietic cells in the bone marrow. To explore the possibility that HTLV-1 infects hematopoietic stem cells (HSCs), we analyzed integration sites of HTLV-1 provirus in various lineages of hematopoietic cells in patients with HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) and a HTLV-1 carrier using the high-throughput sequencing method. Identical integration sites were detected in neutrophils, monocytes, B cells, CD8+ T cells and CD4+ T cells, indicating that HTLV-1 infects HSCs in vivo. We also detected Tax protein in myeloperoxidase positive neutrophils. Furthermore, dendritic cells differentiated from HTLV-1 infected monocytes caused de novo infection to T cells, indicating that infected monocytes are implicated in viral spreading in vivo. Certain integration sites were re-detected in neutrophils from HAM/TSP patients at different time points, indicating that infected HSCs persist and differentiate in vivo. This study demonstrates that HTLV-1 infects HSCs, and infected stem cells differentiate into diverse cell lineages. These data indicate that infection of HSCs can contribute to the persistence and spread of HTLV-1 in vivo. PMID- 29186196 TI - The integration of probabilistic information during sensorimotor estimation is unimpaired in children with Cerebral Palsy. AB - BACKGROUND: It is important to understand the motor deficits of children with Cerebral Palsy (CP). Our understanding of this motor disorder can be enriched by computational models of motor control. One crucial stage in generating movement involves combining uncertain information from different sources, and deficits in this process could contribute to reduced motor function in children with CP. Healthy adults can integrate previously-learned information (prior) with incoming sensory information (likelihood) in a close-to-optimal way when estimating object location, consistent with the use of Bayesian statistics. However, there are few studies investigating how children with CP perform sensorimotor integration. We compare sensorimotor estimation in children with CP and age-matched controls using a model-based analysis to understand the process. METHODS AND FINDINGS: We examined Bayesian sensorimotor integration in children with CP, aged between 5 and 12 years old, with Gross Motor Function Classification System (GMFCS) levels 1-3 and compared their estimation behavior with age-matched typically-developing (TD) children. We used a simple sensorimotor estimation task which requires participants to combine probabilistic information from different sources: a likelihood distribution (current sensory information) with a prior distribution (learned target information). In order to examine sensorimotor integration, we quantified how participants weighed statistical information from the two sources (prior and likelihood) and compared this to the statistical optimal weighting. We found that the weighing of statistical information in children with CP was as statistically efficient as that of TD children. CONCLUSIONS: We conclude that Bayesian sensorimotor integration is not impaired in children with CP and therefore, does not contribute to their motor deficits. Future research has the potential to enrich our understanding of motor disorders by investigating the stages of motor processing set out by computational models. Therapeutic interventions should exploit the ability of children with CP to use statistical information. PMID- 29186197 TI - Fingolimod suppresses neuronal autophagy through the mTOR/p70S6K pathway and alleviates ischemic brain damage in mice. AB - The bioactive, signaling lipid, sphingosine-1-phosphate (S1P), and its analog, fingolimod (FTY720), have previously shown neuroprotective effects against ischemic brain injury. However, the underlying mechanisms have not yet been fully clarified. The roles of autophagy in ischemic stroke are being increasingly recognized. In the present study, we sought to determine whether the S1P pathway is involved in neuronal autophagy and investigate its possible mechanisms following stroke. Interestingly, we found that FTY720 significantly attenuates infarct volumes and reduces neuronal apoptosis on days 1 and 3 post stroke, accompanied by amelioration of functional deficits. Additionally, FTY720 was found to decrease the induction of autophagosome proteins, microtubule-associated protein 1 light chain 3(LC3-II) and Beclin1, following ischemic stroke in a dose dependent manner. Meanwhile, protein levels of the mammalian target of rapamycin (mTOR) and the 70-kDa ribosomal protein, S6 kinase1 (p70S6K), were also up regulated in FTY720-treated animals, and the nonspecific SphK inhibitor, N,N dimethylsphingosine (DMS), was found to cause a reverse effect. Our results indicate that modulation of the S1P signaling pathway by FTY720 could effectively decrease neuronal autophagy through the mTOR/p70S6K pathway and attenuate ischemic brain injury in mice. PMID- 29186198 TI - Safety and efficacy of ferric citrate in patients with nondialysis-dependent chronic kidney disease. AB - Two randomized, placebo-controlled trials conducted in patients with nondialysis dependent (NDD) chronic kidney disease (CKD), iron deficiency anemia, and normal or elevated serum phosphorus demonstrated that ferric citrate (FC) significantly increased hemoglobin and decreased serum phosphate concentrations. Pooling these trial results could provide a more robust evaluation of the safety and efficacy of FC in this population. We pooled results of a phase 2 (n = 149) and 3 trial (n = 233) of patients randomized and treated for up to 12 and 16 weeks, respectively. The starting dose in both trials was three 1-g (elemental iron 210 mg) tablets/day with food, up to 12 tablets/day. Doses were titrated in the phase 2 and 3 trials to lower serum phosphate concentrations to a target range (0.97 1.13 mmol/L) and to achieve a >=10-g/L hemoglobin increase, respectively. Safety was assessed in all patients who received >=1 dose of FC (n = 190) and placebo (n = 188). Treatment-emergent adverse events (AEs) were reported in 143 of 190 (75.3%) FC-treated and 116 of 188 (61.7%) placebo-treated patients; gastrointestinal AEs were the most frequent (94 [49.5%] vs. 52 [27.7%], respectively). Specific events reported in >5% of patients (FC vs. placebo, respectively) included discolored feces (41 [21.6%] vs. 0 [0.0%]), diarrhea (39 [20.5%] vs. 23 [12.2%]), constipation (35 [18.4%] vs. 19 [10.1%]), and nausea (18 [9.5%] vs. 8 [4.3%]). Twenty FC-treated (10.5%) and 21 placebo-treated patients (11.2%) experienced a serious AE. Two patients (1.1%) died in each group. A pooled efficacy assessment demonstrated a consistent hemoglobin rise and modest serum phosphate decline, with few excursions below the normal range. When used for treatment of patients with NDD-CKD, FC contributes to gastrointestinal AEs at higher rates than placebo, while simultaneously correcting two of the principal metabolic manifestations of CKD (iron deficiency anemia and relative hyperphosphatemia). PMID- 29186199 TI - Genetic diversity and population structure of Prunus mira (Koehne) from the Tibet plateau in China and recommended conservation strategies. AB - Prunus mira Koehne, an important economic fruit crop with high breeding and medicinal values, and an ancestral species of many cultivated peach species, has recently been declared an endangered species. However, basic information about genetic diversity, population structure, and morphological variation is still limited for this species. In this study, we sampled 420 P. mira individuals from 21 wild populations in the Tibet plateau to conduct a comprehensive analysis of genetic and morphological characteristics. The results of molecular analyses based on simple sequence repeat (SSR) markers indicated moderate genetic diversity and inbreeding (A = 3.8, Ae = 2.5, He = 0.52, Ho = 0.44, I = 0.95, FIS = 0.17) within P. mira populations. STRUCTURE, GENELAND, and phylogenetic analyses assigned the 21 populations to three genetic clusters that were moderately correlated with geographic altitudes, and this may have resulted from significantly different climatic and environmental factors at different altitudinal ranges. Significant isolation-by-distance was detected across the entire distribution of P. mira populations, but geographic altitude might have more significant effects on genetic structure than geographic distance in partial small-scale areas. Furthermore, clear genetic structure, high genetic differentiation, and restricted gene flow were detected between pairwise populations from different geographic groups, indicating that geographic barriers and genetic drift have significant effects on P. mira populations. Analyses of molecular variance based on the SSR markers indicated high variation (83.7% and 81.7%), whereas morphological analyses revealed low variation (1.30%-36.17%) within the populations. Large and heavy fruits were better adapted than light fruits and nutlets to poor climate and environmental conditions at high altitudes. Based on the results of molecular and morphological analyses, we classified the area into three conservation units and proposed several conservation strategies for wild P. mira populations in the Tibet plateau. PMID- 29186200 TI - Sea-level rise and archaeological site destruction: An example from the southeastern United States using DINAA (Digital Index of North American Archaeology). AB - The impact of changing climate on terrestrial and underwater archaeological sites, historic buildings, and cultural landscapes can be examined through quantitatively-based analyses encompassing large data samples and broad geographic and temporal scales. The Digital Index of North American Archaeology (DINAA) is a multi-institutional collaboration that allows researchers online access to linked heritage data from multiple sources and data sets. The effects of sea-level rise and concomitant human population relocation is examined using a sample from nine states encompassing much of the Gulf and Atlantic coasts of the southeastern United States. A 1 m rise in sea-level will result in the loss of over >13,000 recorded historic and prehistoric archaeological sites, as well as over 1000 locations currently eligible for inclusion on the National Register of Historic Places (NRHP), encompassing archaeological sites, standing structures, and other cultural properties. These numbers increase substantially with each additional 1 m rise in sea level, with >32,000 archaeological sites and >2400 NRHP properties lost should a 5 m rise occur. Many more unrecorded archaeological and historic sites will also be lost as large areas of the landscape are flooded. The displacement of millions of people due to rising seas will cause additional impacts where these populations resettle. Sea level rise will thus result in the loss of much of the record of human habitation of the coastal margin in the Southeast within the next one to two centuries, and the numbers indicate the magnitude of the impact on the archaeological record globally. Construction of large linked data sets is essential to developing procedures for sampling, triage, and mitigation of these impacts. PMID- 29186201 TI - Prognostic markers for survival in patients with oligodendroglial tumors; a single-institution review of 214 cases. AB - BACKGROUND: In the 2016 WHO classification, the diagnosis of oligodendroglioma has been restricted to IDH mutated, 1p19q codeleted tumors (IDHmut-codel). IDHmut oligoastrocytoma is now classified either as oligodendroglioma or astrocytoma based on presence of 1p19q codeletion. There is growing evidence that this molecular classification more closely reflects patient outcome. Due to the strong association between IDHmut-codel with oligodendroglial morphology, the additional impact of these markers on prognostic accuracy is largely unknown. Our aim was to assess the prognostic impact of IDHmut-codel in an unselected cohort of morphologically classified oligodendroglial tumors. METHODS: We performed a retrospective chart review of oligodendroglial tumors (WHO grade II and III) operated since 1983. A total of 214 tumors were included, and molecular information was available for 96 tumors. The prognostic impact of IDHmut-codel together with clinical parameters was analyzed by multivariate Cox regression. RESULTS: IDHmut-codel was registered in 64 tumors while for 150 tumors the molecular profile was negative for IDHmut-codel, unknown or incomplete. Comparison between the two groups showed that patients with IDHmut-codel tumors were younger (42 vs. 48 years), had more frequent frontal tumor location (48 vs. 33%) and presented more often with seizures (72 vs. 51%) and no signs of neurological impairment (14 vs. 30%) than patients harboring tumors with unknown or incomplete molecular profile. Multivariate survival analysis identified young age (HR 1.78 >= 40 years), the absence of neurological deficits or personality changes (HR 0.57), frontal tumor location (HR 0.64) and the presence of IDHmut codel (HR 0.50) as independent predictors for longer survival, whereas tumor grade was not. CONCLUSION: In this unselected single-institution cohort, the presence of IDHmut-codel was associated with more beneficial clinical parameters and was identified as an independent prognostic factor. We conclude that the classical oligodendroglioma genotype provides additional prognostic data beyond clinical characteristics, morphology and tumor grade. PMID- 29186202 TI - Enhanced cell proliferation and osteogenic differentiation in electrospun PLGA/hydroxyapatite nanofibre scaffolds incorporated with graphene oxide. AB - One of the goals of bone tissue engineering is to mimic native ECM in architecture and function, creating scaffolds with excellent biocompatibility, osteoinductive ability and mechanical properties. The aim of this study was to fabricate nanofibrous matrices by electrospinning a blend of poly (L-lactic-co glycolic acid) (PLGA), hydroxyapatite (HA), and grapheme oxide (GO) as a favourable platform for bone tissue engineering. The morphology, biocompatibility, mechanical properties, and biological activity of all nanofibrous matrices were compared. The data indicate that the hydrophilicity and protein adsorption rate of the fabricated matrices were significantly increased by blending with a small amount of HA and GO. Furthermore, GO significantly boosted the tensile strength of the nanofibrous matrices, and the PLGA/GO/HA nanofibrous matrices can serve as mechanically stable scaffolds for cell growth. For further test in vitro, MC3T3-E1 cells were cultured on the PLGA/HA/GO nanofbrous matrices to observe various cellular activities and cell mineralization. The results indicated that the PLGA/GO/HA nanofibrous matrices significantly enhanced adhesion, and proliferation in MCET3-E1 cells and functionally promoted alkaline phosphatase (ALP) activity, the osteogenesis related gene expression and mineral deposition. Therefore, the PLGA/HA/GO composite nanofibres are excellent and versatile scaffolds for applications in bone tissue regeneration. PMID- 29186204 TI - Mocetinostat combined with gemcitabine for the treatment of leiomyosarcoma: Preclinical correlates. AB - Leiomyosarcoma (LMS) is a malignant soft tissue sarcoma (STS) with a dismal prognosis following metastatic disease. Chemotherapeutic intervention has demonstrated to have modest clinical efficacy with no curative potential in LMS patients. Previously, we demonstrated pan-HDAC inhibition to have a superior effect in various complex karyotypic sarcomas. In this study, our goal is to evaluate the therapeutic efficacy of mocetinostat alone and in combination with gemcitabine in LMS. Human leiomyosarcoma (LMS) cell lines were used for in vitro and in vivo studies. Compounds tested included the class I HDAC inhibitor, mocetinostat, and nucleoside analog, gemcitabine. MTS and clonogenic assays were used to evaluate the effect of mocetinostat on LMS cell growth. Cleaved caspase 3/7 analysis was used to determine the effects of mocetinostat on apoptosis. Compusyn software was used to determine in vitro synergy studies for the combination of mocetinostat plus gemcitabine. A LMS xenograft model in SCID mice was used to test the impact of mocetinostat alone, gemcitabine alone and the combination of mocetinostat plus gemcitabine. Mocetinostat abrogated LMS cell growth and clonogenic potential, and enhanced apoptosis in LMS cell lines. The combination of mocetinostat plus gemcitabine exhibited a synergistic effect in LMS cells in vitro. Similarly, mocetinostat combined with gemcitabine resulted in superior anti-LMS effects in vivo. Mocetinostat reduced the expression of gemcitabine-resistance markers RRM1, RRM2, and increased the expression of gemcitabine-sensitivity marker, hENT1, in LMS cells. LMS are aggressive, metastatic tumors with poor prognosis where effective therapeutic interventions are wanting. Our studies demonstrate the potential utility of mocetinostat combined with gemcitabine for the treatment of LMS. PMID- 29186205 TI - Narcolepsy susceptibility gene CCR3 modulates sleep-wake patterns in mice. AB - Narcolepsy is caused by the loss of hypocretin (Hcrt) neurons and is associated with multiple genetic and environmental factors. Although abnormalities in immunity are suggested to be involved in the etiology of narcolepsy, no decisive mechanism has been established. We previously reported chemokine (C-C motif) receptor 3 (CCR3) as a novel susceptibility gene for narcolepsy. To understand the role of CCR3 in the development of narcolepsy, we investigated sleep-wake patterns of Ccr3 knockout (KO) mice. Ccr3 KO mice exhibited fragmented sleep patterns in the light phase, whereas the overall sleep structure in the dark phase did not differ between Ccr3 KO mice and wild-type (WT) littermates. Intraperitoneal injection of lipopolysaccharide (LPS) promoted wakefulness and suppressed both REM and NREM sleep in the light phase in both Ccr3 KO and WT mice. Conversely, LPS suppressed wakefulness and promoted NREM sleep in the dark phase in both genotypes. After LPS administration, the proportion of time spent in wakefulness was higher, and the proportion of time spent in NREM sleep was lower in Ccr3 KO compared to WT mice only in the light phase. LPS-induced changes in sleep patterns were larger in Ccr3 KO compared to WT mice. Furthermore, we quantified the number of Hcrt neurons and found that Ccr3 KO mice had fewer Hcrt neurons in the lateral hypothalamus compared to WT mice. We found abnormalities in sleep patterns in the resting phase and in the number of Hcrt neurons in Ccr3 KO mice. These observations suggest a role for CCR3 in sleep-wake regulation in narcolepsy patients. PMID- 29186203 TI - Chl1 DNA helicase and Scc2 function in chromosome condensation through cohesin deposition. AB - Chl1 DNA helicase promotes sister chromatid cohesion and associates with both the cohesion establishment acetyltransferase Eco1/Ctf7 and the DNA polymerase processivity factor PCNA that supports Eco1/Ctf7 function. Mutation in CHL1 results in precocious sister chromatid separation and cell aneuploidy, defects that arise through reduced levels of chromatin-bound cohesins which normally tether together sister chromatids (trans tethering). Mutation of Chl1 family members (BACH1/BRIP/FANCJ and DDX11/ChlR1) also exhibit genotoxic sensitivities, consistent with a role for Chl1 in trans tethering which is required for efficient DNA repair. Chl1 promotes the recruitment of Scc2 to DNA which is required for cohesin deposition onto DNA. There is limited evidence, however, that Scc2 also directs the deposition onto DNA of condensins which promote tethering in cis (intramolecular DNA links). Here, we test the ability of Chl1 to promote cis tethering and the role of both Chl1 and Scc2 to promote condensin recruitment to DNA. The results reveal that chl1 mutant cells exhibit significant condensation defects both within the rDNA locus and genome-wide. Importantly, chl1 mutant cell condensation defects do not result from reduced chromatin binding of condensin, but instead through reduced chromatin binding of cohesin. We tested scc2-4 mutant cells and similarly found no evidence of reduced condensin recruitment to chromatin. Consistent with a role for Scc2 specifically in cohesin deposition, scc2-4 mutant cell condensation defects are irreversible. We thus term Chl1 a novel regulator of both chromatin condensation and sister chromatid cohesion through cohesin-based mechanisms. These results reveal an exciting interface between DNA structure and the highly conserved cohesin complex.

AB - Helicobacter pylori is a genetically diverse bacterial species that colonizes the stomach in about half of the human population. Most persons colonized by H. pylori remain asymptomatic, but the presence of this organism is a risk factor for gastric cancer. Multiple populations and subpopulations of H. pylori with distinct geographic distributions are recognized. Genetic differences among these populations might be a factor underlying geographic variation in gastric cancer incidence. Relatively little is known about the genomic features of African H. pylori strains compared to other populations of strains. In this study, we first analyzed the genomes of H. pylori strains from seven globally distributed populations or subpopulations and identified encoded proteins that exhibited the highest levels of sequence divergence. These included secreted proteins, an LPS glycosyltransferase, fucosyltransferases, proteins involved in molybdopterin biosynthesis, and Clp protease adaptor (ClpS). Among proteins encoded by the cag pathogenicity island, CagA and CagQ exhibited the highest levels of sequence diversity. We then identified proteins in strains of Western African origin (classified as hspWAfrica by MLST analysis) with sequences that were highly divergent compared to those in other populations of strains. These included ATP dependent Clp protease, ClpS, and proteins of unknown function. Three of the divergent proteins sequences identified in West African strains were characterized by distinct insertions or deletions up to 8 amino acids in length. These polymorphisms in rapidly evolving proteins represent robust genetic signatures for H. pylori strains of West African origin.

AB - Screening for metabolic-related health problems can enhance animal welfare, so the purpose of this study was to conduct the first metabolic health assessment of zoo elephants and use epidemiological methods to determine how factors in the captive environment were associated with metabolic hormone concentrations. In addition, we examined relationships between metabolic status and several fitness parameters: foot health, musculoskeletal health, reproductive cyclicity, and body condition. Two blood samples were collected 2 weeks apart from 87 Asian (Elephas maximus) and 105 African (Loxodonta africana) elephants managed by zoos accredited by the Association of Zoos and Aquariums for analysis of serum leptin, insulin, glucose and the glucose-to-insulin ratio (G:I). In females, mean (+/- SD) leptin concentrations and the G:I were lower (P<0.05) in Asian (3.93 +/- 2.21 ng/ml and 110 +/- 86 units) compared to African (4.37 +/- 2.89 ng/ml and 208 +/- 133 units) elephants, respectively. For males, mean leptin and the G:I were 4.99 +/- 3.61 ng/ml and 253 +/- 181 units for Asian, and 3.72 +/- 2.00 ng/ml and 326 +/- 231 units for African elephants, respectively, with no differences between species (P>0.05). As mean leptin concentration increased there was an increase in the odds of a female being non-cycling (P = 0.0083). The G:I was associated inversely with body condition (P = 0.0002); as the G:I increased there was a decreased risk of BCS = 4 or 5 as compared to the ideal, or BCS = 3. Neither leptin nor G:I were predictive of foot or musculoskeletal health scores. Factors related to walking and feeding practices were most influential in predicting metabolic status, whereas social and housing factors showed smaller, but significant effects. The metabolic health benefits of walking were detected if the time spent in staff-directed walking was 7 hours or more per week. The most protective feeding practices included implementing a random rather than predictable feeding schedule and limiting the number of methods presentation methods. Results indicate that leptin levels and G:I can be used as predictors of both ovarian cycle function and body condition, and are affected by zoo management in elephants. PMID- 29186210 TI - When Reducing Low-Value Care in Hospital Medicine Saves Money, Who Benefits ? AB - One emerging policy solution for deterring low-value care is to financially penalize physicians who prescribe it. However, physicians' willingness to support such policies may depend on whether they perceive that benefits accrue to patients or to insurers and hospitals. We surveyed physicians practicing hospital medicine to evaluate the association between policy support and physician beliefs about who benefits from the money saved through reducing low-value services in hospital medicine. Overall, physicians believed that more of any money saved would go to profits and leadership salaries for insurance companies and hospitals and/or health systems rather than to patients. These beliefs were associated with policy support: 66% of those supporting physician penalties were more likely to believe that benefits accrue to patients or physicians, compared to 39% of those not supporting policies (P < .001). Our findings are consistent with a sense of healthcare justice, in which physicians are less likely to support penalties imposed on themselves if the resulting benefits accrue to corporate or organizational interests. Effective physician penalties will likely need to address the belief that insurers and provider organizations stand to gain more than patients when low-value care services are reduced. PMID- 29186209 TI - Penalizing Physicians for Low-Value Care in Hospital Medicine: A Randomized Survey. AB - Low-value services-those for which there is little to no benefit, little benefit relative to cost, or outsized potential harm compared with benefit-persist widely despite professional consensus, guidelines, and national campaigns to reduce them. As policy makers consider financially penalizing physicians to deter low value services, physician support for such penalties remains unknown. We conducted a randomized survey experiment among physicians to evaluate how the framing of harms from low-value care-in terms of those to patients, healthcare institutions, or society-influenced physician support of financial penalties for low-value care services. Policy support rate was 39.6% overall and highest when the harms of low-value care were framed as costs to society (48.4%). Compared with respondents receiving the "patient harm" version, those receiving the "societal harm" version (adjusted odds ratio [OR] 2.83; 95% confidence interval [CI], 1.20-6.69), but not the "institutional harm" framing (adjusted OR 1.53; 95% CI, 0.66-3.53), were more likely to report policy support. Our results suggest that emphasizing the impact of these harms may increase acceptability of financial penalties among physicians and contribute to the larger effort to decrease low-value care in hospital settings. PMID- 29186208 TI - Cytotoxic effect of albumin coated copper nanoparticle on human breast cancer cells of MDA-MB 231. AB - PURPOSE: The aim of this study was to design a new nanocomposite that would have high cytotoxicity against invasive breast cancer cells and minimum side effects on normal cells. METHODS: An albumin nano-carrier for delivery of CuNPs was developed. The ACuNPs formation was characterized by TEM, DLS and UV-Vis, fluorescence and circular dichroism spectroscopy. The cytotoxic efficacy of the ACuNPs against human breast cancer cells (MDA-MB 231) and normal cells (MCF-10A) was compared using a standard MTT assay. The mechanism of cell death induced by ACuNPs was considered by inverted and fluorescent microscopy, flow cytometry and gel electrophoresis. The effects of compounds on ROS generations in MDA-MB 231 cells were also studied. RESULTS: It was found that the resulted ACuNPs with a diameter of 62.7 nm and zeta potential of about -10.76 mV, are suitable for extravasation into tumor cells. In ACuNPs, the 90% of the secondary structure and almost all the tertiary structure of albumin remained intact. Comparing to CuNPs, ACuNPs could significantly suppress the viability of cancer cells while they were less toxic on normal cells. Compared with the untreated cells, the MDA-MB 231 cell line showed higher levels of ROS production after treatment with ACuNPs. The increase in ROS production after 24 hours indicated that ACuNPs induce apoptosis. CONCLUSIONS: The ACuNPs characteristics such as intact structure of albumin, high toxicity against cancer cells comparing to normal cells and apoptosis induction as the mechanism of cell death, revealed that this nanocomposite is a good candidate to be used as a chemotherapeutic agent against invasive breast cancer cells.

AB - BACKGROUND: OBJECTIVE: DESIGN, SETTING, PATIENTS: INTERVENTION: MEASUREMENTS: CONCLUSIONS: PMID- 29186212 TI - Hospitalist Perspective of Interactions with Medicine Subspecialty Consult Services. AB - BACKGROUND: Medicine subspecialty consultation is becoming increasingly important in inpatient medicine. OBJECTIVE: We conducted a survey study in which we examined hospitalist practices and attitudes regarding medicine subspecialty consultation. DESIGN AND SETTING: The survey instrument was developed by the authors based on prior literature and administered online anonymously to hospitalists at 4 academic medical centers in the United States. MEASUREMENTS: The survey evaluated 4 domains: (1) current consultation practices, (2) preferences regarding consultation, (3) barriers to and facilitating factors of effective consultation, and (4) a comparison between hospitalist-fellow and hospitalist-subspecialty attending interactions. RESULTS: One hundred twenty-two of 261 hospitalists (46.7%) responded. The majority of hospitalists interacted with fellows during consultation. Of those, 90.9% reported that in-person communication occurred during less than half of consultations, and 64.4% perceived pushback at least "sometimes " in their consult interactions. Participants viewed consultation as an important learning experience, preferred direct communication with the consulting service, and were interested in more teaching during consultation. The survey identified a number of barriers to and facilitating factors of an effective hospitalist-consultant interaction, which impacted both hospitalist learning and patient care. Hospitalists reported more positive experiences when interacting with subspecialty attendings compared to fellows with regard to multiple aspects of the consultation. CONCLUSION: The hospitalist-consultant interaction is viewed as important for both hospitalist learning and patient care. Multiple barriers and facilitating factors impact the interaction, many of which are amenable to intervention. PMID- 29186213 TI - Returns to Emergency Department, Observation, or Inpatient Care Within 30 Days After Hospitalization in 4 States, 2009 and 2010 Versus 2013 and 2014. AB - BACKGROUND: Nationally, readmissions have declined for acute myocardial infarction (AMI) and heart failure (HF) and risen slightly for pneumonia, but less is known about returns to the hospital for observation stays and emergency department (ED) visits. OBJECTIVE: To describe trends in rates of 30-day, all cause, unplanned returns to the hospital, including returns for observation stays and ED visits. DESIGN: By using Healthcare Cost and Utilization Project data, we compared 210,007 index hospitalizations in 2009 and 2010 with 212,833 matched hospitalizations in 2013 and 2014. SETTING: Two hundred and one hospitals in Georgia, Nebraska, South Carolina, and Tennessee. PATIENTS: Adults with private insurance, Medicaid, or no insurance and seniors with Medicare who were hospitalized for AMI, HF, and pneumonia. MEASUREMENTS: Thirty-day hospital return rates for inpatient, observation, and ED visits. RESULTS: Return rates remained stable among adults with private insurance (15.1% vs 15.3%; P = 0.45) and declined modestly among seniors with Medicare (25.3% vs 25.0%; P = 0.04). Increases in observation and ED visits coincided with declines in readmissions (8.9% vs 8.2% for private insurance and 18.3% vs 16.9% for Medicare, both P <= 0.001). Return rates rose among patients with Medicaid (31.0% vs 32.1%; P = 0.04) and the uninsured (18.8% vs 20.1%; P = 0.004). Readmissions remained stable (18.7% for Medicaid and 9.5% for uninsured patients, both P > 0.75) while observation and ED visits increased. CONCLUSIONS: Total returns to the hospital are stable or rising, likely because of growth in observation and ED visits. Hospitalists' efforts to improve the quality and value of hospital care should consider observation and ED care.

PMID- 29186215 TI - Revisiting monosaccharide analysis - quantitation of a comprehensive set of monosaccharides using dynamic multiple reaction monitoring. AB - A rapid method for the quantitation of sixteen neutral and acidic monosaccharides, from both animal and plant sources was developed using ultra high performance liquid chromatography triple quadrupole mass spectrometry (UHPLC/QqQ-MS) in dynamic multiple reaction monitoring (dMRM) mode. Monosaccharides including three pentoses (ribose, xylose, arabinose), two deoxyhexoses (rhamnose, fucose), five hexoses (fructose, mannose, allose, glucose, galactose), two hexuronic acids (glucuronic acid, galacturonic acid), and two N-acetyl-hexosamines (GlcNAc, GalNAc), were derivatized with 1-phenyl-3 methyl-5-pyrazolone (PMP), while underivatized sialic acids, Neu5Ac and Neu5Gc, were simultaneously analyzed with a 10-minute run. With the optimized UHPLC conditions, baseline separations of the isomers were achieved. The sensitivity and calibration ranges of this method were determined. The limits of detection were between femtomoles and attomoles with linear ranges spanning four to six orders of magnitude and coefficients of variation (CVs) <=7.2%. Spiking experiments performed on a pooled fecal sample demonstrated the high accuracy of this method even when applied to samples with complicated matrices. The validated method was applied to fecal samples from an infant transitioning from breast milk to weaning foods. Major milk monosaccharides including galactose, fucose, glucose, GlcNAc, and Neu5Ac were found to be the most abundant components in the feces of milk-fed infants. PMP-derivatives of nine other monosaccharides including apiose, lyxose, altrose, talose, gulose, glucosamine, galactosamine, mannosamine, and N-acetylmannosamine (ManNAc) were also tested and could be added to the quantitation method depending on the need. The speed and sensitivity of the method makes it readily adaptable to rapid throughput analysis of monosaccharides in biological samples.

PMID- 29186219 TI - Fullerenes - how 25 years of charge transfer chemistry have shaped our understanding of (interfacial) interactions. AB - In this review article, we highlight over 25 years of fullerene research in charge transfer chemistry. The major thrust of this work is to illustrate interfacial interactions between fullerenes and porphyrins in electron donor acceptor conjugates as well as self-assembled associates and co-crystallites all the way to organic photovoltaics. Hereby, the analysis of the fundamental proceses, namely, energy transfer, charge shift, charge separation as well as charge recombination stand at the forefront. Our examples, illustrate on how fine tuning the structure leads to substantial alteration of interfacial interactions. PMID- 29186220 TI - Self-assembly of water-soluble silver nanoclusters: superstructure formation and morphological evolution. AB - Supramolecular self-assembly, based on non-covalent interactions, has been employed as an efficient approach to obtain various functional materials from nanometer-sized building blocks, in particular, [Ag6(mna)6]6-, mna = mercaptonicotinate (Ag6-NC). A challenging issue is how to modulate the self assembly process through regulating the relationship between building blocks and solvents. Herein, we report the controlled self-assembly of hexanuclear silver nanoclusters into robust multilayer vesicles in different solvents, DMSO, CH3CN, EG and MeOH. Their unique luminescence enables them to be bifunctional probes to sense Fe3+ and dl-dithiothreitol (DTT). By protonating the Ag6-NC to Ag6-H-NC using hydrochloric acid (HCl), the multilayer vesicles survive in aprotic solvents, DMSO and CH3CN, but are transformed to nanowires in protic solvents, water, EG and MeOH. Our results demonstrated that the solvent-bridged H-bond plays a key role in the evolution of the morphologies from vesicles to nanowires. Moreover, the nanowires could further hierarchically self-assemble in water into hydrogels with high water content (99.5%), and with remarkable mechanical strength and self-healing properties. This study introduces a robust cluster based building block in a supramolecular self-assembly system and reveals the significance of aprotic and protic solvents for the modulation of the morphologies of cluster-based aggregates.

AB - We explored the use of irreversible electroporation (IRE) and high-frequency irreversible electroporation (H-FIRE) to induce cell death of tumor-initiating cells using a mouse ovarian surface epithelial (MOSE) cancer model. Tumor initiating cells (TICs) can be successfully destroyed using pulsed electric field parameters common to irreversible electroporation protocols. Additionally, high frequency pulses seem to induce cell death of TICs at significantly lower electric fields suggesting H-FIRE can be used to selectively target TICs and malignant late-stage cells while sparing the non-malignant cells in the surrounding tissue. We evaluate the relationship between threshold for cell death from H-FIRE pulses and the capacitance of cells as well as other properties that may play a role on the differences in the response to conventional IRE versus H FIRE treatment protocols.

AB - Doping metal nanoclusters with a second type of metal is a powerful method for tuning the physicochemical properties of nanoclusters at the atomic level and it also provides opportunities for a fundamental understanding of alloying rules as well as new applications. Herein, we have devised a new, one-phase strategy for achieving heavy Ag-doping in Au25(SR)18 nanoclusters. This strategy overcomes the light doping of silver by previous methods. X-ray crystallography together with ESI-MS determined the composition of the product to be [AgxAu25-x(SC6H11)18]- with x ~ 21. Cryogenic optical spectroscopy (80-300 K) revealed fine features in optical absorption peaks. Interestingly, the heavy doping of silver does not significantly change the electron-phonon coupling strength and the surface phonon frequency. DFT simulations reproduced the experimentally observed trend of electronic structure evolution with Ag doping. We further investigated the electrocatalytic performance of such heavily Ag-doped nanoclusters for oxygen reduction in alkaline solutions. The mass activity of ligand-off [AgxAu25 x(SC6H11)18]- nanoclusters (217.4 A g-1metal) was determined to be higher than that of ligand-on nanoclusters (29.6 A g-1metal) at a potential of -0.3 V (vs. Ag/AgCl). The rotating disk electrode (RDE) studies revealed the tunable kinetic features of the nanoclusters by ligand removal. PMID- 29186225 TI - Enhanced broadband photoresponse of a self-powered photodetector based on vertically grown SnS layers via the pyro-phototronic effect. AB - Here, we demonstrate the broadband photoresponse from ultraviolet (365 nm) to near-infrared (850 nm) wavelengths from a photodetector based on vertically grown SnS layers. Particularly, the photoinduced current density of the device increased from 100 to 470 MUA cm-2 with a wavelength of 760 nm and an intensity of 7 mW cm-2 by utilizing the pyro-phototronic potential. In addition, the photodetector demonstrated ultrafast response rates of ~12 MUs for the rise and ~55 MUs for the decay times over the studied range. Moreover, a good photoresponsivity of 13 mA W-1 and a high photodetectivity of 3 * 1014 Jones at a wavelength of 760 nm with an intensity of 7 mW cm-2 were measured, representing enhancements of 340% and 3960%, respectively, with the pyroelectric potential. This excellent broadband performance was attributed to the photon-induced pyroelectric effect in the vertically grown SnS layers, which also modulated the optoelectronic processes. This novel approach will open a new avenue to design a broadband ultrafast device for advanced optoelectronics. PMID- 29186226 TI - Organic semiconductor crystals. AB - Organic semiconductors have attracted a lot of attention since the discovery of highly doped conductive polymers, due to the potential application in field effect transistors (OFETs), light-emitting diodes (OLEDs) and photovoltaic cells (OPVs). Single crystals of organic semiconductors are particularly intriguing because they are free of grain boundaries and have long-range periodic order as well as minimal traps and defects. Hence, organic semiconductor crystals provide a powerful tool for revealing the intrinsic properties, examining the structure property relationships, demonstrating the important factors for high performance devices and uncovering fundamental physics in organic semiconductors. This review provides a comprehensive overview of the molecular packing, morphology and charge transport features of organic semiconductor crystals, the control of crystallization for achieving high quality crystals and the device physics in the three main applications. We hope that this comprehensive summary can give a clear picture of the state-of-art status and guide future work in this area. PMID- 29186227 TI - "Snorkelling" vs. "diving" in mixed micelles probed by means of a molecular bathymeter. AB - A photoactive bathymeter based on a carboxylic acid moiety covalently linked to a signalling methoxynaphthalene (MNP) fluorophore has been designed to prove the concept of "snorkelling" vs. "diving" in mixed micelles (MM). The carboxylic acid "floats" on the MM surface, while the MNP unit sinks deep in MM. The rate constants of MNP fluorescence quenching by iodide, which remains basically in water, consistently decrease with increasing spacer length, revealing different regions. This is associated with the distance MNP should "dive" in MM to achieve protection from aqueous reactants. Unequivocal proof of the exergonic photoinduced electron transfer was obtained from the UV-visible spectral signature of I3- upon steady-state photolysis. The applicability of the bathymeter was examined upon testing a family of MNP derivatives. The obtained results were validated by comparison with different lipophilicity tests: (i) a modified version of the Kow partition coefficient and (ii) the retention factor on thin layer chromatography. This concept could potentially be extended to test drugs or pharmacophores exhibiting any photoactive moiety.

AB - Herein, tungsten-coated nano-boron carbide (W-WB4-WCx/B4C) particles were prepared by heating a mixture of B4C and W powder using a spark plasma coating (SPC) method. During the discharge treatment process, metal W in the mixture is activated and reacts with B4C to form WCx, WB4, and graphite nanoribbons. The oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) performance of W-WB4-WCx/B4C is tested in an alkaline solution, and the results show that the W-WB4-WCx/B4C composite electrocatalyst exhibits a low overpotential of 0.36 V at 10 mA cm-2 for the OER, a small overpotential of -0.19 V (j = 10 mA cm-2) for the HER, as well as good stability. The significantly enhanced electrocatalytic performance of the W-WB4-WCx/B4C composites is attributed to their unique structure, in which WCx and WB4 not only improve the catalytic activity for the OER and HER, but also effectively anchor the W coating on the substrate.

AB - Halogen-halogen interactions are a particularly interesting class of halogen bonds that are known to be essential design elements in crystal engineering. In solution, it is likely that halogen-halogen interactions also play a role, but the weakness of this interaction makes it difficult to characterize or even simply detect. We have designed a supramolecular balance that allows detecting BrBr interactions between CBr3 groups in solution and close to room temperature. The sensitivity and versatility of the chosen platform have allowed accumulating consistent data. In halogenoalkane solvents, we propose estimates for the free energy of these weak halogen bond interactions. In toluene solutions, we show that the interactions between Br atoms and the solvent aromatic groups dominate over the BrBr interactions.

AB - We analyze the environment-induced fluctuation of pigment excitation energies in the Fenna-Matthews-Olson (FMO) complex from various perspectives, by employing an interpolation-based all-atom potential energy model for describing realistic pigment vibrations. We conduct molecular dynamics simulations on a 100 ns timescale, which is an extent that can enclose the effect of static disorder, and demonstrate its timescale separation from fast dynamic disorder. We extract the spectral densities of the complex by considering both the site and the exciton bases. We show that exciton delocalization reduces the effective environmental fluctuation and rationalize this aspect based on a model of fluctuating molecular aggregates. We also obtained the spectral density of the lowest exciton state under low temperature conditions and show that it reasonably well reproduces the experimental result. Finally, by additionally performing non-equilibrium excited state trajectory simulations, we show that the system lies well within the linear response regime after photo-absorption and that the pigments do not visit anharmonic regions of the potential surface to a significant extent. This indicates that methodologies based on harmonic bath models are indeed reasonable approaches for describing the excited state dynamics of the FMO complex. PMID- 29186229 TI - HyRes: a coarse-grained model for multi-scale enhanced sampling of disordered protein conformations. AB - Efficient coarse-grained (CG) models can be coupled with atomistic force fields to accelerate the sampling of atomistic energy landscapes in the multi-scale enhanced sampling (MSES) framework. This approach may be particularly suitable for generating atomistic conformational ensembles of intrinsically disordered proteins (IDPs). While MSES is relatively robust to inherent CG artifacts, achieving optimal sampling efficiency requires CG modeling to generate the local and long-range fluctuations that are largely consistent with those at the atomistic level. Here, we describe a new hybrid resolution CG model (HyRes) for MSES simulations of disordered protein states, which is specifically designed to provide semi-quantitative secondary structure propensities together with a qualitative description of long-range nonspecific interactions. The HyRes model contains an atomistic description of the backbone with intermediate resolution side chains. The secondary structure propensities are tuned by adjusting the backbone hydrogen-bonding strength and the phi/psi torsion profile. The sizes and covalent geometries of the side chains are parameterized to reproduce distributions derived from atomistic simulations. Lennard-Jones parameters for sidechain beads are assigned to reproduce statistical potentials derived from the protein structural database, and then globally parameterized with nonspecific electrostatic interactions to reproduce the free energy profiles of pair wise interactions and the key conformational properties of model peptides. Application of HyRes to MSES simulations of small IDPs suggests that it is capable of driving faster structural transitions at the atomistic level and increasing the convergence rate compared to the Calpha-only Go-like models previously utilized. With further optimization, we believe that the new CG model could greatly improve the efficiency of MSES simulations of the larger and more complex IDPs frequently involved in cellular signalling and regulation. PMID- 29186232 TI - Why do the Togni reagent and some of its derivatives exist in the high-energy hypervalent iodine form? New insight into the origins of their kinetic stability. AB - In a recent study published in ChemComm, H. F. Schaefer and coworkers showed that the Togni trifluoromethyltation reagent and some of its derivatives appear in a high-energy hypervalent form. The (kinetic) stability of these reagents is granted by the five-membered ring of their benziodoxole-based scaffold, which prevents isomerization to the (inactive) acyclic ether form. Whereas the thermodynamic stability of these reagents can be predicted on the basis of the trans influence of the electrophilic substituent, no such descriptor was found for their kinetic stability. In this study, we explore an array of Togni-type reagents, and show that the barrier to isomerization can be predicted based on the bond length between the iodine atom and the electrophilic substituent. For compounds, where this correlation does not hold, we have a reliable indication that the structure of the transition state is at variance with those in the series. PMID- 29186233 TI - A new strategy to address the challenges of nanoparticles in practical water treatment: mesoporous nanocomposite beads via flash freezing. AB - Various engineering nanoparticles (NPs) exhibit high reactivity and great potential for water decontamination. Encapsulation of NPs into millimeter-sized polymer hosts is a very promising strategy to address their inherent bottlenecks for scale-up water treatment such as aggregation, difficult operation and potential risks when released into water. However, the inevitable host pore blockage accompanying NP loadings significantly compromise their decontamination reactivity. Herein, a newly developed flash freezing method was utilized to embed alpha-Fe2O3 NPs (3 nm, 7 nm and 18 * 90 nm) inside millimetric polystyrene to prepare mesoporous nanocomposites Fe2O3@PS. All the as-obtained Fe2O3@PS nanocomposites feature high mesoporosity, well-dispersed NPs and highly accessible sites. The amount of Fe-OH species, i.e., the active sites for As(v) sequestration, of the embedded 3 nm-Fe2O3 is dramatically increased 3.6 times over the bare NPs, resulting in higher adsorption capacity and affinity. The 3 nm Fe2O3@PS is capable of producing clean water 2000-fold greater in mass successively in column adsorption, with As(v) reducing from 176 MUg L-1 initially to <1 MUg L-1. Also, Fe2O3@PS can be readily regenerated for cyclic use with negligible NPs leaking into water. This study provides an elaborate strategy to address the trade-off between easy operation and decontamination reactivity of NPs for water treatment.

AB - The kinetics of the reaction of CH2OO with ozone has been studied by monitoring CH2OO using time-resolved infrared (IR) absorption spectroscopy, which utilized the fast chirped IR pulse train from a quantum cascade laser [J. Chem. Phys., 2017, 146, 244302]. CH2OO was prepared by photolyzing a gas mixture of CH2I2/O2/O3 at 352 nm; the photolysis wavelength was chosen to minimize the photodissociation of O3. The measured rate coefficient at 298 K and 30 Torr is (6.7 +/- 0.5) * 10-14 cm3 s-1, independent of pressure from 30 to 100 Torr. The result indicates that previous ab initio calculations either underestimated or overestimated this reaction rate by one order of magnitude or more. The result also implies that, the reaction of the Criegee intermediate with ozone may play a role in laboratory studies of ozonolysis of alkenes. However, this reaction would not compete with other CH2OO sinks in the atmosphere. PMID- 29186235 TI - Coating ZnO nanoparticle films with DNA nanolayers for enhancing the electron extracting properties and performance of polymer solar cells. AB - Here we present for the first time polymer solar cells that incorporate biological material that show state of the art efficiencies in excess of 8%. The performance of inverted polymer solar cells was improved significantly after deposition of ZnO nanoparticles (ZnO-NPs) together with a thin deoxyribonucleic acid nanolayer and used as an electron extraction layer (EEL). The ZnO-NPs/DNA double layer improved the rectifying ratio, shunt resistance of the cells as well as lowering the work function of the electron-collecting contact. Importantly, the ZnO-NPs/DNA bilayer enhanced the power conversion efficiency of cells considerably compared to cells with EELs made of only DNA (improvement of 56% in relative terms) or only ZnO-NPs (improvement of 19% in relative terms) reaching a best power conversion efficiency of 8.5%. The ZnO-NPs/DNA double layer cells also outperformed ones made with one of the most efficient previous synthetic composite EELs (i.e. ZnO/PEIE(poly(ethyleneimine)-ethoxylated)). Since all fabrication procedures were carried out at low (<150 degrees C) or room temperature, we have applied the findings to flexible substrates as well as on glass obtaining a high PCE of 7.2%. The solar cells with the biological/metal oxide composite EELs also delivered an improvement in the stability (~20% in relative term) compared to that with ZnO-NPs only. All these findings show that natural materials, in this case DNA, the premium biological material, can be incorporated in organic semiconductor devices in tandem with inorganic devices delivering uncompromising levels of performance as well as significant improvements. PMID- 29186236 TI - Quasi physisorptive two dimensional tungsten oxide nanosheets with extraordinary sensitivity and selectivity to NO2. AB - Attributing to their distinct thickness and surface dependent physicochemical properties, two dimensional (2D) nanostructures have become an area of increasing interest for interfacial interactions. Effectively, properties such as high surface-to-volume ratio, modulated surface activities and increased control of oxygen vacancies make these types of materials particularly suitable for gas sensing applications. This work reports a facile wet-chemical synthesis of 2D tungsten oxide nanosheets by sonication of tungsten particles in an acidic environment and thermal annealing thereafter. The resultant product of large nanosheets with intrinsic substoichiometric properties is shown to be highly sensitive and selective to nitrogen dioxide (NO2) gas, which is a major pollutant. The strong synergy between polar NO2 molecules and tungsten oxide surface and also abundance of active surface sites on the nanosheets for molecule interactions contribute to the exceptionally sensitive and selective response. An extraordinary response factor of ~30 is demonstrated to ultralow 40 parts per billion (ppb) NO2 at a relatively low operating temperature of 150 degrees C, within the physisorption temperature band for tungsten oxide. Selectivity to NO2 is demonstrated and the theory behind it is discussed. The structural, morphological and compositional characteristics of the synthesised and annealed materials are extensively characterised and electronic band structures are proposed. The demonstrated 2D tungsten oxide based sensing device holds the greatest promise for producing future commercial low-cost, sensitive and selective NO2 gas sensors.

AB - In order to obtain an optimal therapeutic effect with minimal systemic toxicity, a redox-responsive mesoporous silica nanoparticle (MSN)-based platform modified with protoporphyrin IX (PpIX)-multifunctional peptides was synthesized as an intelligent theranostic agent carrier. This redox-responsive nanoplatform could release the theranostic agent under a glutathione stimulus, produce fluorescence recovery for tumor-specific fluorescence imaging and provide tumor-enhanced photodynamic therapy. PMID- 29186238 TI - Electrochemical aspects of photocatalysis: Au@FeS2 nanocomposite for removal of industrial pollutant. AB - A wide range of endeavors have been dedicated to building up an impetus in the field of catalysis to enhance the removal of toxic contaminants from water. This study characterizes an efficient photocatalyst for water treatment technique. Herein, the synthesis of a photocatalyst Au@FeS2 for the degradation of textile dye NOVACRON Red Huntsman (NRH) has been demonstrated. Photocatalysis under visible light with varying concentrations of catalyst have been explored along with the degradation kinetics to determine the synergistic impact on degradation technique. The Au@FeS2 exhibits excellent photocatalytic activity and good reusability under visible light irradiation. The efficiency of Au@FeS2 (1 g L-1) in the degradation of the textile dye NRH (1 mg L-1) is found to be 96.02% in just 60 minutes, which is considerably higher than that of FeS2 (1 g L-1) (95.63% in 120 minutes). The electrochemical performance also supports the enhanced photocatalytic activity of Au@FeS2. The photocatalytic and electrochemical activity of Au@FeS2 offers an innovative platform for environmental remediation applications. PMID- 29186239 TI - Cutaneous mucormycosis. AB - Cutaneous mucormycosis is an emerging fungal infection caused by opportunistic fungi of the phylum Glomeromycota. It is frequent in poorly controlled diabetic patients and individuals with immunosuppression. It is usually acquired by direct inoculation through trauma. The clinical presentation is nonspecific, but an indurated plaque that rapidly evolves to necrosis is a common finding. Diagnosis should be confirmed by demonstration of the etiological agent and new molecular diagnostic tools have recently been described. It is an invasive life-threatening disease and in order to improve survival, a prompt diagnosis and multidisciplinary management should be provided. The treatment of choice is amphotericin B, but new azoles, such as posaconazole and isavuconazole, must be considered. PMID- 29186240 TI - Evaluation of treatment response to autologous transplantation of noncultured melanocyte/keratinocyte cell suspension in patients with stable vitiligo. AB - BACKGROUND: Vitiligo is a chronic disease characterized by the appearance of achromic macules caused by melanocyte destruction. Surgical treatments with melanocyte transplantation can be used for stable vitiligo cases. OBJECTIVES: To evaluate treatment response to the autologous transplantation of noncultured epidermal cell suspension in patients with stable vitiligo. METHODS: Case series study in patients with stable vitiligo submitted to noncultured epidermal cell suspension transplantation and evaluated at least once, between 3 and 6 months after the procedure, to observe repigmentation and possible adverse effects. The maximum follow-up period for some patients was 24 months. RESULTS: Of the 20 patients who underwent 24 procedures, 25% showed an excellent rate of repigmentation, 50% good repigmentation, 15% regular, and 10% poor response. The best results were observed in face and neck lesions, while the worst in extremity lesions (88% and 33% of satisfactory responses, respectively). Patients with segmental vitiligo had a better response (84%) compared to non-segmental ones (63%). As side effects were observed hyperpigmentation of the treated area and the appearance of Koebner phenomenon in the donor area. STUDY LIMITATIONS: Some limitations of the study included the small number of patients, a subjective evaluation, and the lack of long-term follow-up on the results. CONCLUSION: Noncultured epidermal cell suspension transplantation is efficient and well tolerated for stable vitiligo treatment, especially for segmental vitiligo on the face and neck. PMID- 29186241 TI - Clinical features of von Zumbusch type of generalized pustular psoriasis in children: a retrospective study of 26 patients in southwestern China. AB - BACKGROUND: Von Zumbusch type of generalized pustular psoriasis is a rare variant of psoriasis in children. It can occur in patients with or without psoriasis vulgaris. OBJECTIVE: The aim of the study was to discuss the precipitating factors, clinical manifestations, laboratory data and therapy of von Zumbusch type of generalized pustular psoriasis in children from southwestern China and to improve the diagnosis and treatment level. METHODS: A retrospective analysis was conducted for inpatients aged 14 years old or less with von Zumbusch type of generalized pustular psoriasis in our department from 2005 to 2014. RESULTS: A total of 26 patients were included, of whom four (15.38%) had previous history of psoriasis vulgaris and one (3.85%) had previous history of psoriasis arthropathica. Mean onset age was 6.90 years. Gender distribution was equivalent. Incidence of the disease in summer and autumn was higher than that in winter and spring. Nineteen (73.08%) cases were triggered by infection, two (7.69%) cases were caused by sudden discontinuation of systemic use of corticosteroid. Twenty four (92.31%) cases had concomitant fever. The initial lesion manifested as non follicular sterile pustules on erythema. Sixteen patients responded well to acitretin, 11 to Tripterygium wilfordii Hook F (TwHF), two to cyclosporine, and one to methotrexate. STUDY LIMITATIONS: This study is a retrospective one and the number of cases is small. CONCLUSION: Von Zumbusch type of generalized pustular psoriasis is a rare disease in children, infection is the most common precipitating factor, acitretin is the first-line therapy, traditional Chinese medicine TwHF also can be used. PMID- 29186242 TI - Study of serum levels and skin expression of S100B protein in psoriasis. AB - BACKGROUND: S100B protein was reported to be elevated in psoriatic patients' serum, with no previous evaluation of its skin expression, in contrast to the extensively studied S100 protein. OBJECTIVE: To evaluate the serum level and skin expression of S100B in psoriasis to assess its possible involvement in its pathogenesis. METHODS: Serum level of S100B protein was estimated in 40 psoriatic patients of different clinical varieties and 10 healthy controls. S100B protein expression was assessed immunohistochemically in lesional and non-lesional skin of patients and in normal skin of controls. Relation to disease severity was also evaluated. RESULTS: Serum level of S100B protein was significantly higher in psoriatic patients (0.15+/-0.03 ug/l) than in controls (0.03+/-0.007 ug/l) (P value <0.001) with no significant correlation with PASI score. On comparing grades of S100B protein skin expression in lesional and non-lesional skin biopsies, a statistically significant difference was found (P=0.046) with higher percentage of strong S100B skin expression (60%) in non-lesional than in lesional (42%) skin. All the control biopsies showed negative expression. STUDY LIMITATIONS: Relatively small sample size with a limited range of low PASI scores. CONCLUSION: This study points to a potential link between psoriasis and S100B protein with higher serum and skin expression in patients than in controls. PMID- 29186243 TI - Familial progressive hyper- and hypopigmentation: a report on a Chinese family and evidence for genetic heterogeneity. AB - BACKGROUND: Familial progressive hyper- and hypopigmentation (FPHH) is a rare genodermatosis that is characterized by diffuse hyper- and hypopigmented spots on the skin and mucous membranes. It is caused by a pathogenic mutation of the KITLG gene. OBJECTIVES: To investigate the clinical features and mutation of the KITLG gene in a Chinese family with FPHH. METHODS: Histopathological and immunohistochemical analysis of lesions from the proband was performed. The KITLG gene was screened for the presence of mutations. RESULTS: A Chinese family containing 14 individuals with FPHH was described, and the proband was a 5-year old girl showing diffuse hyper- and hypopigmented lesions on her extremities and trunk. Histopathological and immunohistochemical staining for S100 and HMB45 of skin biopsy specimens from the hyperpigmented areas showed a striking increase in melanin throughout the epidermis, especially in the basal cell layer, and staining of hypopigmented area specimens displayed lower levels of melanin in the epidermis. Mutation analysis of the KITLG gene was performed, but no mutation was found. STUDY LIMITATIONS: The new pathogenic gene was not found. CONCLUSION: A family with FPHH was described. Analysis revealed that its members did not have any mutations of the KITLG gene, which provided evidence for genetic heterogeneity of this genodermatosis. PMID- 29186244 TI - Limitation of activity and restriction of social participation in relation to age range, gender, and education in people with leprosy. AB - BACKGROUND: In Brazil, 38,000 new cases of leprosy are discovered each year, making it a public health problem. OBJECTIVE: To identify whether or not there is an association between activity limitations and the restriction of social participation with some demographic data (age range, gender, and education) of the patients in a Basic Health Unit (BHU), diagnosed with leprosy. METHODS: The SALSA scale was used to assess activity limitations, whereas the Participation scale was used to assess the restriction of social participation. RESULTS: The assessments were conducted with 31 BHU patients diagnosed with leprosy. Males were the most affected by leprosy, the multibacillary was the most prevalent, and education proved to be an important factor when related to the disease injuries among the evaluated individuals. Regarding activity limitations and the restriction of social participation, the percentage of individuals without limitations and without restrictions was greater in both scales. STUDY LIMITATIONS: The main limitation is the small study sample. CONCLUSION: It can be concluded that, for the studied sample, no association was observed between the activity limitations, evaluated by the Salsa scale, nor the restriction of social participation, evaluated by the Participation Scale, with the analyzed demographic data. PMID- 29186245 TI - Dermoscopic patterns of melanocytic nevi in children and adolescents: a cross sectional study. AB - BACKGROUND: Childhood is a dynamic period regarding nevogenesis. Dermoscopy is a noninvasive technique, recommended for the evaluation of pigmented cutaneous lesions. OBJECTIVES: The purpose of this study was to describe the structures and dermoscopic patterns of melanocytic nevi observed in children and adolescents. METHODS: Dermoscopy with photographic documentation was used for nevi located on the face, trunk, and extremities of 38 patients aged from one to 16 years examined at the Pediatric Dermatology Outpatient Clinic of the Federal University of Sao Paulo. RESULTS: The study included 201 skin lesions that were diagnosed as nevi during clinic examination. Upon evaluation of the global dermoscopic pattern of the lesions, the most frequently observed nevi were reticular (39.0%), followed by homogeneous (23.9%) and globular nevi (16.4%). During evaluation of the dermoscopic structures, according to the body site, the pigment network was the most observed in the extremities. STUDY LIMITATIONS: A limitation to be considered is that the inclusion of small or new lesions may hinder the differentiation between dots and globules. CONCLUSIONS: In our study, the most observed pattern was reticular. There was a difference in the predominance of structures dependent on the anatomical location. PMID- 29186246 TI - Severe cutaneous adverse drug reactions of Chinese inpatients: a meta-analysis. AB - BACKGROUND: The rate of severe cutaneous adverse drug reactions is low, and these reactions can result in death or disability. An evidence-based epidemiological study of severe cutaneous adverse drug reactions in China has not been reported. OBJECTIVE: The aim of this study was to analyze epidemiology and characteristics of severe cutaneous adverse drug reactions of Chinese inpatients during the recent 15 years with meta-analysis. METHODS: We retrospectively reviewed Chinese literature reporting severe cutaneous adverse drug reactions and collecting data from 2000 to 2015, which were in accordance with our inclusion criteria. All included data were analyzed with the Launch Open Meta-Analyst software. RESULTS: Twenty-five articles involving 928 cases with severe cutaneous adverse drug reactions were included. Men to women ratio was 1.14:1. Twenty-one per cent of the patients had drug allergy history. Antibiotics (26.0%), sedative hypnotics and anticonvulsants (21.6%), and antipyretic analgesics (17.1%) were the most common causative drugs. The most frequent clinical subtype was Stevens-Johnson syndrome (50.1%), followed by toxic epidermal necrolysis (25.4%), exfoliative dermatitis (21.0%) and drug-induced hypersensitivity syndrome (1.6%). In addition to skin rashes, patients with severe cutaneous adverse drug reactions suffered mostly from fever (73%), and blood routine abnormality (66.7%). STUDY LIMITATIONS: This meta-analysis is limited by its retrospective design and by its methodological variation. CONCLUSION: The most common causative drugs were antibiotics and sedative hypnotics and anticonvulsants. Stevens-Johnson syndrome was the most frequent clinical subtype of severe cutaneous adverse drug reactions. In addition to skin rashes, patients with severe cutaneous adverse drug reactions suffered mostly from fever, mucosal lesion, and hematologic abnormalities. PMID- 29186247 TI - A new optical intra-tissue fiber irradiation ALA-PDT in the treatment of acne vulgaris in rabbit model: improved safety and tolerability. AB - BACKGROUND: Photodynamic therapy with topical aminolevulinic acid (ALA-PDT) has been suggested to be effective in treatment of acne vulgaris. However, adverse events occur during and after treatment. OBJECTIVES: To compare the efficacy and tolerability of optical intra-tissue fiber irradiation (OFI) ALA-PDT versus traditional ALA-PDT in treatment of acne vulgaris in rabbit models. METHODS: Twenty-five rabbits of clean grade were used. Twenty rabbits were randomly selected to establish acne model and the other five were used as control. Rabbits in model group (40 ears) were further divided into four groups (10 ears/group): I, OFI-ALA-PDT with the head of optical fiber inserted into the target lesion (intra-tissue); II, traditional ALA-PDT group; III, OFI group; IV, blank control group without any treatment. Uncomfortable symptoms, adverse events, and effectiveness rates were recorded on post-treatment day 14, 30, and 45. RESULTS: On post-treatment day 14, the effectiveness rate in OFI-ALA-PDT group was obviously higher than that of the other three groups (P<0.05). However, no improved effects were observed in OFI-ALA-PDT group on day 30 and 45. During the period of treatment, the frequencies of uncomfortable symptoms in ALA-PDT group were obviously higher than those in the other three groups (P<0.05). The adverse event rate in OFI-ALA-PDT group was obviously lower than that of the ALA-PDT group (P<0.05). STUDY LIMITATIONS: The unblindness of the study and temporary animal models of acne induced may hamper the assessment and monitoring of the results, and future studies are still needed to clarify it further. CONCLUSION: The OFI-ALA-PDT group (intra-tissue irradiation) showed no improved efficacy on treating rabbit ear acne but had higher safety and better tolerability. PMID- 29186248 TI - Antioxidants in dermatology. AB - The skin cells continuously produce, through cellular respiration, metabolic processes or under external aggressions, highly reactive molecules oxidation products, generally called free radicals. These molecules are immediately neutralized by enzymatic and non-enzymatic systems in a physiological and dynamic balance. In situations where this balance is broken, various cellular structures, such as the cell membrane, nuclear or mitochondrial DNA may suffer structural modifications, triggering or worsening skin diseases. several substances with alleged antioxidant effects has been offered for topical or oral use, but little is known about their safety, possible associations and especially their mechanism of action. The management of topical and oral antioxidants can help dermatologist to intervene in the oxidative processes safely and effectively, since they know the mechanisms, limitations and potential risks of using these molecules as well as the potential benefits of available associations. PMID- 29186249 TI - Tretinoin peel: a critical view. AB - The tretinoin peel, also known as retinoic acid peel, is a superficial peeling often performed in dermatological clinics in Brazil. The first study on this was published in 2001, by Cuce et al., as a treatment option for melasma. Since then, other studies have reported its applicability with reasonable methodology, although without a consistent scientific background and consensus. Topical tretinoin is used for the treatment of various dermatoses such as acne, melasma, scars, skin aging and non-melanoma skin cancer. The identification of retinoids cellular receptors was reported in 1987, but a direct cause-effect relation has not been established. This article reviews studies evaluating the use of topical tretinoin as agent for superficial chemical peel. Most of them have shown benefits in the treatment of melasma and skin aging. A better quality methodology in the study design, considering indication and intervention is indispensable regarding concentration, vehicle and treatment regimen (interval and number of applications). Additionally, more controlled and randomized studies comparing the treatment with tretinoin cream versus its use as a peeling agent, mainly for melasma and photoaging, are necessary. PMID- 29186250 TI - An overview about oxidation in clinical practice of skin aging. AB - Free radicals are unstable chemical species, highly reactive, being formed by cellular entities of different tissues. Increased production of these species without proper effective action of endogenous and exogenous antioxidant systems, generates a condition of oxidative stress, potentially provider of skin disorders that extend from functional impairments (skin cancer, dermatitis, chronic and acute inflammatory processes) even aesthetic character, with the destruction of structural proteins and cellular changes with the appearance of stains, marks and lines of expressions and other signs inherent to the intrinsic and extrinsic skin aging process. The antioxidants are chemical substances commonly used in clinical practice for topical application and may contribute in the fight against the radical species responsible for many skin damage. This paper summarized the main evidence of the benefits brought by the topical application of antioxidants in the skin, considering the amplitude of the indicative performance of antioxidant activity by in vitro and ex-vivo tests as well as in vivo tests. It is recognized that a breadth of product performance tests should be explored to truly identify the effectiveness of antioxidant products for an anti-aging effect. PMID- 29186251 TI - Histopathological diagnosis of small melanocytic lesions suspicious for malignant melanoma. AB - The concern about malignant skin neoplasms leads to the excision of smaller lesions. This study on small melanocytic lesions aims to evaluate the range of possible histopathological diagnoses, describe histopathological aspects, and assess the usefulness of serial histological sections. We performed a cross sectional descriptive histopathological study examining 76 pigmented skin lesions up to 6 mm in diameter. Histopathological diagnoses included atypical melanocytic nevi (n=38), common melanocytic nevi (n=18), atypical lentiginous melanocytic hyperplasia with architectural features of atypical melanocytic nevi (n=7), lentigo simplex (n=2), and malignant melanoma (n=1). Ten cases were non diagnostic. Cytological atypia was not an exclusive finding of atypical lesions. Examination of serial sections did not change histopathological impression. Early detection of malignant melanoma is important, but clinical and dermoscopy exams may be leading to the resection of a great number of benign lesions. Strict attention to histopathological criteria results in a large number of non diagnostic cases. PMID- 29186252 TI - Pigmented Kamino bodies: a little-known histological finding. Prevalence in 19 cases of Reed nevus. AB - The present study aimed to determine the prevalence of Kamino bodies in Reed nevus, since most studies to date show conflicting data on this issue. This was a retrospective observational study, in which the histopathology of 19 Reed nevus lesions were reviewed. The slides were stained by hematoxylin and eosin and periodic acid-Schiff, with a special focus placed on the identification of Kamino bodies. Some clinical data were also collected. The median patient age was 12 years (range of 2 to 58). The women to men ratio was 5:4. Lesions were located on different parts of the body. Kamino bodies were found in eleven lesions (57.89%). five showed pigmented Kamino bodies (26.31%), four non-pigmented Kamino bodies (21,05%), and 2 (10.52%) had both. Kamino bodies, pigmented or not, are a common histological finding in Reed nevus and may well represent a good marker to differentiate these from malignant melanomas. PMID- 29186253 TI - Crusted scabies due to indiscriminate use of glucocorticoid therapy in infant. AB - Crusted or Norwegian scabies is a parasitic infectious disease caused by Sarcoptes scabiei var. hominis that mainly affects immunocompromised individuals and those with neurological patients. We report a case of crusted scabies in a 4 month-old infant who had been treated erroneously for atopic dermatitis with high doses of corticosteroids. This initial misdiagnosis associated with the abusive use of corticosteroid facilitated the evolution of scabies to crusted scabies and its main complications of secondary infection and sepsis. PMID- 29186254 TI - Merkel cell carcinoma in an immunosuppressed patient. AB - Merkel cell carcinoma is an uncommon neuroendocrine carcinoma with a rising incidence and an aggressive behavior. It predominantly occurs in older patients, with onset occurring at a mean age of 75-80 years. Recognized risk factors are ultraviolet sunlight exposure, immunosuppression, and, more recently, Merkel cell polyomavirus. We report a case of Merkel cell carcinoma in a young HIV positive patient with Merkel Cell polyomavirus detected in the tumor. PMID- 29186255 TI - Lepromatous leprosy simulating rheumatoid arthritis - Report of a neglected disease. AB - Brazil has the second largest number of leprosy cases in the world; nevertheless, late diagnosis is common. We report the case of a male patient with pain and numbness in both hands and feet for six years with positive rheumatoid factor and anticardiolipin under rheumatoid arthritis treatment for five years. Examination revealed diffuse cutaneous infiltration and leonine facies, characteristic features of lepromatous leprosy. Autoantibodies such as rheumatoid factor and anticardiolipin are markers of rheumatic autoimmune diseases, but their presence is also described in leprosy. We report the present case in order to alert health professionals to remember leprosy, even in areas where the disease is considered eliminated as a public health problem, avoiding misinterpretations of serologic findings and misdiagnosis. PMID- 29186256 TI - Angiolymphoid hyperplasia with eosinophilia versus Kimura's disease: a case report and a clinical and histopathological comparison. AB - Angiolymphoid hyperplasia with eosinophilia is a rare and benign vascular tumor whose etiology remains uncertain. It clinically presents itself by angiomatous papules or nodules located on the head and neck. Many controversies in the literature are found in relation to angiolymphoid hyperplasia with eosinophilia and Kimura's disease - its main differential diagnosis - due to their clinical and histopathological similarities. However, currently, most studies agree that they are distinct diseases. The present case illustrates a characteristic description of angiolymphoid hyperplasia with eosinophilia and also highlights the main differences with Kimura's disease. PMID- 29186258 TI - Vulvar melanoma: relevant aspects in therapeutic management. AB - Cancer of the vulva accounts for at least 1% of malignant neoplasms among women. Although rare, vulvar melanoma is the second most common histological type of vulvar cancer, representing 7-10% of all malignant vulvar neoplasms. Initial symptoms are non-specific and complete excision of the lesion is indicated in cases with suspected diagnosis. Prognosis of patients with these neoplasms is poor and remains unchanged despite the treatment approach. Hemivulvectomy with lymph node dissection is the current procedure of choice, associated or not with adjuvant therapies. We report two cases of patients presenting with late diagnosed vulvar melanoma and the relevant aspects in their therapeutic management. PMID- 29186257 TI - Lymphangioma secondary to irradiation after mastectomy. AB - Lymphangioma is a rare benign disease of the lymphatic vessels. Typically, they are primary conditions but may be acquired secondarily, such as those caused by irradiation during radiotherapy for the treatment of breast cancer. The local lymphatic obstruction provoked by irradiation causes the appearance of asymptomatic hyaline vesicles on the irradiated skin. The present report describes a 78-year-old female patient, who initially presented hyaline vesicles that progressed into multiple papules with serous exudation of a yellowish and odorless secretion on the area of chronic radiodermitis in right breast. Despite the rarity of the case, we emphasize the importance of knowledge regarding dermatological disease for early diagnosis and proper medical conduct. PMID- 29186259 TI - Pneumocystis jirovecii pneumonia induced by low-dose methotrexate in a patient with chronic urticaria. AB - Methotrexate has immunosuppressive effects and is administered for refractory chronic urticaria. We present a case of Pneumocystis jirovecii pneumonia in a patient with refractory chronic urticaria managed by low-dose weekly methotrexate treatment (total cumulative dose 195mg). Our study highlights the importance of providing prompt diagnosis and treatment of Pneumocystis jirovecii pneumonia in patients with chronic urticaria under methotrexate therapy. PMID- 29186260 TI - Acute generalized exanthematous pustulosis induced by hydroxychloroquine: a case with atypical clinical presentation. AB - Acute generalized exanthematous pustulosis is a rare drug-induced eruption that is characterized by acute, nonfollicular sterile pustules on an erythematous and edematous base. The most frequently implicated drugs are beta-lactam antibiotics. Hydroxychloroquine has been widely used to treat dermatologic and rheumatologic diseases and has been reported as a rare cause of acute generalized exanthematous pustulosis. A 42-year-old female presented with pustular lesions on the skin surface with erythema, facial edema, and occasional atypical target-like lesions after 21 days of treatment with 200mg/day hydroxychloroquine for rheumatoid arthritis, diagnosed one month previously. We report a case with acute generalized exanthematous pustulosis induced by hydroxychloroquine and treated with dapsone and systemic corticosteroid. PMID- 29186262 TI - Solitary ulcerated plaque on the face - an unusual presentation of cutaneous plasmacytosis? AB - Cutaneous and systemic plasmacytosis is a rare disorder characterized by cutaneous polyclonal plasma cell infiltration frequently associated with polyclonal hypergammaglobulinemia and lymphadenopathy. We report a case of a 67 year-old woman with an inflammatory ulcerated plaque in the left masseter region. A skin biopsy showed dense perivascular infiltrate of mature plasma cells in the dermis without atypia and immunoglobulin light chain restriction. After physical examination and further investigation, we ruled out systemic disease. Our patient was successfully treated only with hydrocortisone cream application. Few cases of isolated benign primary cutaneous plasmacytosis have been described, particularly in children. After excluding the diagnosis of a reactive process to an infection, which is unlikely in this case, we suspected of a rare manifestation of primary cutaneous plasmacytosis in adults with distinct presentation and clinical course. PMID- 29186261 TI - Cutaneous sarcoidosis and secondary open-angle glaucoma in a patient: case report and literature review. AB - The current report presents the case of a 41-year-old male patient with a two month history of asthenopia and plaques in the frontotemporal region. Computed tomography revealed bilateral hilar and mediastinal lymphadenopathy. Ophthalmological examination showed elevated intraocular pressure. Skin biopsy demonstrated aa dermal inflammatory infiltrate composed mainly of epithelioid cells and a few multinucleated giant cells, but no obvious lymphocytes. Findings of thorough physical examinations and auxiliary examinations suggested the presence of cutaneous sarcoidosis and secondary open-angle glaucoma. Treatment consisted mainly of oral methylprednisolone. Skin lesions, bilateral hilar, and mediastinal lymphadenopathy resolved completely. Cutaneous sarcoidosis is often accompanied by extracutaneous organ involvement. Dermatologists must be aware of the disease's extracutaneous manifestations to ensure accurate diagnosis for further treatments. PMID- 29186263 TI - White piedra, black piedra, tinea versicolor, and tinea nigra: contribution to the diagnosis of superficial mycosis. AB - Superficial mycoses are fungal infections restricted to the stratum corneum and to the hair shafts, with no penetration in the epidermis; they are: white piedra, black piedra, tinea versicolor, and tinea nigra. This study presents images of mycological tests performed in the laboratory, as well as exams performed at the authors office, in order to improve the dermatologist's knowledge about the diagnosis of these dermatoses, which are common in many countries. PMID- 29186264 TI - Do you know this syndrome? Clouston syndrome. AB - Ectodermal dysplasias are conditions that present primary defects in two or more tissues of ectodermal origin and can be classified as hypohidrotic and hidrotic. Hidrotic ectodermal dysplasia or Clouston syndrome is an autosomal dominant genodermatosis and appears as a triad of clinical findings: palmoplantar keratoderma, nail dystrophy, and hypotrichosis. The hair is sparse and brittle. The nails become thickened and dystrophic, which is an essential characteristic of the syndrome. The diagnosis is made based on clinical findings. This study reports a case of a patient who began with changes in hair, nails and palmoplantar keratoderma in early childhood. PMID- 29186265 TI - Case for diagnosis. Patch granuloma annulare. AB - A 59-year-old woman reported a 20-day history of slightly scaly erythematous infiltrated patches on her palms and soles with a histopathological result which was consistent with interstitial-pattern granuloma annulare, clinically classified as patch granuloma annulare. This is a rare clinical variant of granuloma annulare, with an unknown incidence and characteristic clinical and histopathological features. The patient evolved with a complete remission of the lesions after biopsy and the use of high-potency topical corticosteroid. PMID- 29186266 TI - Allergy to hypoallergenic nail polish: does this exist? AB - The main allergen responsible for contact dermatitis to nail polish is tosylamide formaldehyde resin. The so-called hypoallergenic nail polishes are suposedly free of agents that commonly trigger reactions. The commercially available products and their compositions were studied. It was observed that most brands present at least one component capable of triggering the disease; therefore, allergic reaction may occur even when hypoallergenic polishes are used. There should be a proper investigation of the specific allergen through a patch test, because more than one component can cause an allergy, and we need to check the exact composition of each product. PMID- 29186267 TI - Incidence of skin diseases diagnosed in a public institution: comparison between 2003 and 2014. AB - Epidemiology of diseases is influenced by population socio-demographic circumstances. Therefore it can be modified along the time. There are no studies exploring epidemiological transition in dermatology. This study investigated the incidence of dermatoses in new patients from a Brazilian country town public service in 2003 and 2014. There was a significant increase in the incidence of sexually transmitted diseases, leprosy, melasma, pruritus and hidradenitis suppurativa. However, a prominent reduction in scheduling of appointments for surgeries of benign lesions, drug reactions, urticaria and superficial mycoses was detected. The identification of epidemiological trends guides the dimensioning of health system and professional qualification policies. PMID- 29186268 TI - Quality of life in men diagnosed with anogenital warts. AB - Anogenital warts are a worldwide public health problem. They consist of epithelial proliferations caused by HPV, whose transmission occurs mainly through sexual intercourse. In this study, we evaluated their impact on the quality of life of adult males. We interviewed 88 men in an outpatient clinic for sexually transmitted diseases at a Brazilian public institution, using the DLQI-BRA questionnaire. Most patients (81%) presented mild or no impairment of quality of life. The main dimensions affected were sex life, symptoms, and embarrassment. The low impact on quality of life may well justify the delay in seeking medical treatment, favoring the spread of the disease. PMID- 29186269 TI - Aryl hydrocarbon receptor overexpression in miniaturized follicles in female pattern hair loss. AB - The etiopathogenesis of female pattern hair loss is still poorly understood. In addition to genetic and hormonal elements, environmental factors could be involved. The aryl hydrocarbon receptor is expressed in keratinocytes and can be activated by environmental pollutants leading to alterations in the cell cycle, inflammation, and apoptosis. Here we demonstrate the overexpression of nuclear aryl hydrocarbon receptors in miniaturized hair follicles in female pattern hair loss.

PMID- 29186278 TI - Dependence Levels as Interim Clinical Milestones Along the Continuum of Alzheimer's Disease: 18-Month Results from the GERAS Observational Study. AB - BACKGROUND: While functional loss forms part of the current diagnostic criteria used to identify dementia due to Alzheimer's disease, the gradual and progressive nature of the disease makes it difficult to recognize clinically relevant signposts that could be helpful in making treatment and management decisions. Having previously observed a significant relationship between stages of functional dependence (the level of assistance patients require consequent to Alzheimer's disease deficits, derived from the Alzheimer's Disease Cooperative Study - Activities of Daily Living Scale) and cognitive severity, we investigated whether measures of functional dependence could be utilized to identify clinical milestones of Alzheimer's disease progression. OBJECTIVES: To describe the patterns of change in dependence over the course of 18 months in groups stratified according to cognitive Alzheimer's disease dementia severity (determined using the Mini-Mental State Examination score) and to identify characteristics associated with patients showing worsening dependence (progressors) versus those showing no change or improvement (non-progressors). DESIGN: Analysis of longitudinal data from the GERAS study. SETTING: GERAS is an 18-month prospective, multicenter, naturalistic, observational cohort study reflecting the routine care of patients with Alzheimer's disease in France, Germany, and the United Kingdom. PARTICIPANTS: 1495 community-living patients, aged >=55 years, diagnosed with probable Alzheimer's disease dementia, and their caregivers. MEASUREMENTS: Dependence levels, cognitive function, behavioral symptoms, caregiver burden, and cost were assessed at baseline and at 18 months. RESULTS: Of 971 patients having both baseline and 18-month data, 42% (408) were progressors and 563 (58%) were non-progressors. This general pattern held for all three levels of baseline Alzheimer's disease dementia severity - mild (Mini Mental State Examination score 21-26), moderate (15-20) or moderately severe/severe (<15) - with 40-45% of each group identified as progressors and 55 60% as non-progressors. No baseline differences were seen between progressors and non-progressors in cognitive scores or behavioral symptoms, although progressors had significantly shorter times since diagnosis and showed milder functional impairment. Baseline factors predictive of increasing dependence over 18 months included more severe cognitive impairment, living with others, and having multiple caregivers. A higher level of initial dependence was associated with less risk of dependence progression. Total societal costs of care also increased with greater dependence. CONCLUSIONS: In this large cohort, 42% of Alzheimer's disease dementia patients at all levels of cognitive severity became more dependent within 18 months of observation while 58% did not progress. Dependence levels may be considered as meaningful interim clinical milestones that reflect Alzheimer's disease-related functional deficits, although a time frame that extends beyond 18 months may be necessary to observe changes if used in clinical trials or other longitudinal studies. Recognition of predictors of greater dependence offers opportunities for intervention. PMID- 29186279 TI - Albumin, Hemoglobin, and the Trajectory of Cognitive Function in Community Dwelling Older Japanese: A 13-Year Longitudinal Study. AB - BACKGROUND: Cognitive function can substantially decline over a long period, and understanding the trajectory of cognitive function is important. However, little is known about the linkage between nutritional biomarkers and long-term cognitive change. OBJECTIVES: We analyzed 13-year longitudinal data for older Japanese to examine the associations of serum albumin and hemoglobin levels with the trajectory of cognitive function. DESIGN: Longitudinal study. SETTING: Community based. PARTICIPANTS: A total of 1,744 community-dwelling adults aged 65 years or older who participated in annual health examinations in Kusatsu town, Gunma Prefecture, Japan, from 2002-2014. MEASUREMENTS: Cognitive function was assessed annually by the Mini-Mental State Examination (MMSE). Albumin and hemoglobin levels at baseline (the year when a respondent first participated in the health examination) were divided into quartiles. Hierarchical linear modeling was used to analyze intrapersonal and interpersonal differences in cognitive function. RESULTS: Participants' MMSE scores decreased at an accelerated rate over the 13 year period. Participants with the lowest baseline albumin level (below the first quartile line) showed a greater accelerated decline in MMSE scores over time, compared with those with the highest level (above the third quartile line). Moreover, MMSE scores in participants with a lower hemoglobin level and lower MMSE score at baseline tended to decline faster over time at an accelerated rate. CONCLUSIONS: These findings yield new insights about the complex and diverse roles of these nutritional biomarkers on the trajectory of cognitive function in old age. PMID- 29186280 TI - FACEHBI: A Prospective Study of Risk Factors, Biomarkers and Cognition in a Cohort of Individuals with Subjective Cognitive Decline. Study Rationale and Research Protocols. AB - BACKGROUND: Long-term longitudinal studies with multimodal biomarkers are needed to delve into the knowledge of preclinical AD. Subjective cognitive decline has been proposed as a risk factor for the development of cognitive impairment. Thus, including individuals with SCD in observational studies may be a cost-effective strategy to increase the prevalence of preclinical AD in the sample. OBJECTIVES: To describe the rationale, research protocols and baseline characteristics of participants in the Fundacio ACE Healthy Brain Initiative (FACEHBI). DESIGN: FACEHBI is a clinical trial (EudraCT: 2014-000798-38) embedded within a long-term observational study of individuals with SCD. SETTING: Participants have been recruited at the memory clinic of Fundacio ACE (Barcelona) from two different sources: patients referred by a general practitioner and individuals from an Open House Initiative. PARTICIPANTS: 200 individuals diagnosed with SCD with a strictly normal performance in a comprehensive neuropsychological battery. MEASUREMENTS: Individuals will undergo an extensive neuropsychological protocol, risk factor assessment and a set of multimodal biomarkers including florbetaben PET, structural and functional MRI, diffusion tensor imaging, determination of amyloid species in plasma and neurophthalmologic assessment with optical coherence tomography. RESULTS: Two hundred individuals have been recruited in 15 months. Mean age was 65.9 years; mean MMSE was 29.2 with a mean of 14.8 years of education. CONCLUSIONS: FACEHBI is a long-term study of cognition, biomarkers and lifestyle that has been designed upon an innovative symptom-based approach using SCD as target population. It will shed light on the pathophysiology of preclinical AD and the role of SCD as a risk marker for the development of cognitive impairment. PMID- 29186281 TI - EU/US/CTAD Task Force: Lessons Learned from Recent and Current Alzheimer's Prevention Trials. AB - At a meeting of the EU/US/Clinical Trials in Alzheimer's Disease (CTAD) Task Force in December 2016, an international group of investigators from industry, academia, and regulatory agencies reviewed lessons learned from ongoing and planned prevention trials, which will help guide future clinical trials of AD treatments, particularly in the pre-clinical space. The Task Force discussed challenges that need to be addressed across all aspects of clinical trials, calling for innovation in recruitment and retention, infrastructure development, and the selection of outcome measures. While cognitive change provides a marker of disease progression across the disease continuum, there remains a need to identify the optimal assessment tools that provide clinically meaningful endpoints. Patient- and informant-reported assessments of cognition and function may be useful but present additional challenges. Imaging and other biomarkers are also essential to maximize the efficiency of and the information learned from clinical trials. PMID- 29186282 TI - Ethical Issues in the Development of Readiness Cohorts in Alzheimer's Disease Research. AB - There is growing interest in the development of novel approaches to secondary prevention trials in Alzheimer's disease to facilitate screening and recruitment of research participants and to reduce the time and costs associated with clinical trials. Several international research collaborations are setting up research infrastructures that link existing research cohorts, studies or patient registries to establish 'trial-ready' or 'readiness' cohorts. From these cohorts, individuals are recruited into clinical trial platforms. In setting up such research infrastructures, researchers must make ethically challenging design decisions in at least three areas: re-contacting participants in existing research studies, obtaining informed consent for participation in a readiness cohort, and disclosure of Alzheimer's disease-related biomarkers. These ethical considerations have been examined by a dedicated workgroup within the European Prevention of Alzheimer's Dementia (EPAD) project, a trans-European longitudinal cohort and adaptive proof-of-concept clinical trial platform. This paper offers recommendations for the ethical management of re-contact, informed consent and risk disclosure which may be of value to other research collaborations in the process of developing readiness cohorts for prevention trials in Alzheimer's disease and other disease areas. PMID- 29186283 TI - Intracellular trafficking of transforming growth factor beta receptors. AB - Transforming growth factor beta (TGFbeta) family members signal via heterotetrameric complexes of type I (TbetaRI) and type II (TbetaRII) dual specificity kinase receptors. The availability of the receptors on the cell surface is controlled by several mechanisms. Newly synthesized TbetaRI and TbetaRII are delivered from the Golgi apparatus to the cell surface via separate routes. On the cell surface, TGFbeta receptors are distributed between different microdomains of the plasma membrane and can be internalized via clathrin- and caveolae-mediated endocytic mechanisms. Although receptor endocytosis is not essential for TGFbeta signaling, localization of the activated receptor complexes on the early endosomes promotes TGFbeta-induced Smad activation. Caveolae mediated endocytosis, which is widely regarded as a mechanism that facilitates the degradation of TGFbeta receptors, has been shown to be required for TGFbeta signaling via non-Smad pathways. The importance of proper control of TGFbeta receptor intracellular trafficking is emphasized by clinical data, as mislocalization of receptors has been described in connection with several human diseases. Thus, control of intracellular trafficking of the TGFbeta receptors together with the regulation of their expression, posttranslational modifications and down-regulation, ensure proper regulation of TGFbeta signaling. PMID- 29186284 TI - CALQ: compression of quality values of aligned sequencing data. AB - Motivation: Recent advancements in high-throughput sequencing technology have led to a rapid growth of genomic data. Several lossless compression schemes have been proposed for the coding of such data present in the form of raw FASTQ files and aligned SAM/BAM files. However, due to their high entropy, losslessly compressed quality values account for about 80% of the size of compressed files. For the quality values, we present a novel lossy compression scheme named CALQ. By controlling the coarseness of quality value quantization with a statistical genotyping model, we minimize the impact of the introduced distortion on downstream analyses. Results: We analyze the performance of several lossy compressors for quality values in terms of trade-off between the achieved compressed size (in bits per quality value) and the Precision and Recall achieved after running a variant calling pipeline over sequencing data of the well-known NA12878 individual. By compressing and reconstructing quality values with CALQ, we observe a better average variant calling performance than with the original data while achieving a size reduction of about one order of magnitude with respect to the state-of-the-art lossless compressors. Furthermore, we show that CALQ performs as good as or better than the state-of-the-art lossy compressors in terms of variant calling Recall and Precision for most of the analyzed datasets.

AB - Maternal obesity induces pregnancy complications and disturbs fetal development, but the specific mechanisms underlying these outcomes are unclear. Circadian rhythms are implicated in metabolic complications associated with obesity, and maternal metabolic adaptations to pregnancy. Accordingly, obesity-induced circadian dysfunction may drive adverse outcomes in obese pregnancy. This study investigated whether maternal obesity alters the rhythmic expression of clock genes and associated nuclear receptors across maternal, fetal, and placental tissues. Wistar rats were maintained on a cafeteria (CAF) diet prior to and throughout gestation to induce maternal obesity. Maternal and fetal liver and placental labyrinth zone (LZ) were collected at four-hourly time points across days 15-16 and 21-22 of gestation (term = 23 days). Gene expression was analyzed by RT-qPCR. Expression of the accessory clock gene Nr1d1 was rhythmic in the maternal and fetal liver and LZ of chow-fed controls, but in each case CAF feeding reduced peak Nr1d1 expression. Obesity resulted in a phase advance (approx. 1.5 h) in the rhythms of several clock genes and Ppar-delta in maternal liver. Aside from Nr1d1, expression of clock genes was mostly arrhythmic in LZ and fetal liver, and was unaffected by the CAF diet. In conclusion, maternal obesity suppressed Nr1d1 expression across maternal, fetal, and placental compartments and phase-advanced the rhythms of maternal hepatic clock genes. Given the key role of Nr1d1 in regulating metabolic, vascular, and inflammatory processes, our data suggest that disruptions to rhythmic Nr1d1 expression in utero may contribute to programmed health complications in offspring of obese pregnancies. PMID- 29186287 TI - Utility of the Personality Assessment Inventory in detecting feigned Attention Deficit/Hyperactivity Disorder (ADHD): The Feigned Adult ADHD index. AB - Objective: The high potential for secondary gain among college students presenting for Attention-Deficit/Hyperactivity Disorder (ADHD) evaluations highlights the need for psychometrically sound embedded validity indicators. The purpose of this study was to develop new validity indicators specific to feigned ADHD for the Personality Assessment Inventory (PAI) and compare them to preexisting imbedded PAI validity measures. Method: PAI scales that were theoretically related to feigned ADHD were evaluated. A binomial (ADHD simulators, n = 138, and genuine ADHD, n = 142) logistic regression was conducted with selected PAI scales and subscales. Classification rates were compared between the new and existing validity scales. A similar approach was used for item-level data in a second study in a subgroup of the original sample. Results: The derived PAI scale-based logistic regression had a sensitivity of 54% and specificity of 92%. This algorithm accurately identified 97% of healthy controls as not feigning ADHD and correctly identified 98% of a no diagnosis group and 75% of a mood/anxiety disorders group. Classification accuracy of the new index was superior to the majority of existing PAI validity scales across groups. An item level PAI algorithm had a sensitivity of 85% and specificity of 97% for identifying feigned ADHD. Conclusions: New validity measures were compared to existing PAI validity indicators and performed better than many of them in this study. The algorithms developed in this study of ADHD simulators and genuine ADHD cases have adequate sensitivity and good specificity and appear to function differently than other PAI symptom validity scales. PMID- 29186288 TI - Reproducible and flexible simulation experiments with ML-Rules and SESSL. AB - Summary: The modeling language ML-Rules allows specifying and simulating complex systems biology models at multiple levels of organization. The development of such simulation models involves a wide variety of simulation experiments and the replicability of generated simulation results requires suitable means for documenting simulation experiments. Embedded domain-specific languages, such as SESSL, cater both requirements. With SESSL, the user can integrate diverse simulation experimentation methods and third-party software components into an executable, readable simulation experiment specification. A newly developed SESSL binding for ML-Rules exploits these features of SESSL, opening up new possibilities for executing and documenting simulation experiments with ML-Rules models.

PMID- 29186291 TI - Sex Differences in the Behavioral Desensitization of Water Intake Observed After Repeated Central Injections of Angiotensin II. AB - Previous in vivo and in vitro studies demonstrate that the angiotensin type 1 receptor rapidly desensitizes after exposure to angiotensin II (AngII). Behaviorally, this likely underlies the reduced drinking observed after acute repeated central injections of AngII. To date, this phenomenon has been studied exclusively in male subjects. Because there are sex differences in the dipsogenic potency of AngII, we hypothesized that sex differences also exist in desensitization caused by AngII. As expected, when male rats were pretreated with AngII, they drank less water after a test injection of AngII than did rats pretreated with vehicle. Intact cycling female rats, however, drank similar amounts of water after AngII regardless of the pretreatment. To probe the mechanism underlying this sex difference, we tested the role of gonadal hormones in adult and developing rats. Gonadectomy in adults did not produce a male-like propensity for desensitization of water intake in female rats, nor did it produce a female-like response in male rats. To test if neonatal brain masculinization generated a male-like responsiveness, female pups were treated at birth with vehicle, testosterone propionate (TP), or dihydrotestosterone (DHT). When tested as adults, TP-treated female rats showed a male-like desensitization after repeated AngII that was not found in vehicle- or DHT-treated rats. Together, these data reveal a striking sex difference in the behavioral response to elevated AngII that is mediated by organizational effects of gonadal hormones and provide an example of one of the many ways that sex influences the renin angiotensin-aldosterone system. PMID- 29186293 TI - Early histone H4 acetylation during chromatin remodeling in equine spermatogenesis. AB - Chromatin remodeling during spermatogenesis culminates in the exchange of nucleosomes for transition proteins and protamines as an important part of spermatid development to give rise to healthy sperm. Comparative immunofluorescence analyses of equine and murine testis histological sections were used to characterize nucleoprotein exchange in the stallion. Histone H4 hyperacetylation is considered a key event of histone removal during the nucleoprotein transition to a protamine-based sperm chromatin structure. In the stallion, but not the mouse, H4 was already highly acetylated in lysine residues K5, K8, and K12 in round spermatids almost immediately after meiotic division. Time courses of transition protein 1 (TP1), protamine 1, H2A histone family member Z (H2AFZ), and testis-specific histone H2B variant (TH2B) expression in stallion spermatogenesis were similar to the mouse where protamine 1 and TP1 were only expressed in elongating spermatids much later in spermatid development. The additional acetylation of H4 in K16 position (H4K16ac) was detected during a brief phase of spermatid elongation in both species, concomitant with the phosphorylation of the noncanonical histone variant H2AFX resulting from DNA strand break-mediated DNA relaxation. The results suggest that H4K16 acetylation, which is dependent on DNA damage signaling, may be more important for nucleosome replacement in spermiogenesis than indicated by data obtained in rodents and highlight the value of the stallion as an alternative animal model for investigating human spermatogenesis. A revised classification system of the equine spermatogenic cycle for simplified comparison with the mouse is proposed to this end. PMID- 29186292 TI - SATORI: a system for ontology-guided visual exploration of biomedical data repositories. AB - Motivation: The ever-increasing number of biomedical datasets provides tremendous opportunities for re-use but current data repositories provide limited means of exploration apart from text-based search. Ontological metadata annotations provide context by semantically relating datasets. Visualizing this rich network of relationships can improve the explorability of large data repositories and help researchers find datasets of interest. Results: We developed SATORI-an integrative search and visual exploration interface for the exploration of biomedical data repositories. The design is informed by a requirements analysis through a series of semi-structured interviews. We evaluated the implementation of SATORI in a field study on a real-world data collection. SATORI enables researchers to seamlessly search, browse and semantically query data repositories via two visualizations that are highly interconnected with a powerful search interface.

PMID- 29186294 TI - Classifying next-generation sequencing data using a zero-inflated Poisson model. AB - Motivation: With the development of high-throughput techniques, RNA-sequencing (RNA-seq) is becoming increasingly popular as an alternative for gene expression analysis, such as RNAs profiling and classification. Identifying which type of diseases a new patient belongs to with RNA-seq data has been recognized as a vital problem in medical research. As RNA-seq data are discrete, statistical methods developed for classifying microarray data cannot be readily applied for RNA-seq data classification. Witten proposed a Poisson linear discriminant analysis (PLDA) to classify the RNA-seq data in 2011. Note, however, that the count datasets are frequently characterized by excess zeros in real RNA-seq or microRNA sequence data (i.e. when the sequence depth is not enough or small RNAs with the length of 18-30 nucleotides). Therefore, it is desired to develop a new model to analyze RNA-seq data with an excess of zeros. Results: In this paper, we propose a Zero-Inflated Poisson Logistic Discriminant Analysis (ZIPLDA) for RNA seq data with an excess of zeros. The new method assumes that the data are from a mixture of two distributions: one is a point mass at zero, and the other follows a Poisson distribution. We then consider a logistic relation between the probability of observing zeros and the mean of the genes and the sequencing depth in the model. Simulation studies show that the proposed method performs better than, or at least as well as, the existing methods in a wide range of settings. Two real datasets including a breast cancer RNA-seq dataset and a microRNA-seq dataset are also analyzed, and they coincide with the simulation results that our proposed method outperforms the existing competitors.

PMID- 29186295 TI - Systematic analysis and prediction of type IV secreted effector proteins by machine learning approaches. AB - In the course of infecting their hosts, pathogenic bacteria secrete numerous effectors, namely, bacterial proteins that pervert host cell biology. Many Gram negative bacteria, including context-dependent human pathogens, use a type IV secretion system (T4SS) to translocate effectors directly into the cytosol of host cells. Various type IV secreted effectors (T4SEs) have been experimentally validated to play crucial roles in virulence by manipulating host cell gene expression and other processes. Consequently, the identification of novel effector proteins is an important step in increasing our understanding of host pathogen interactions and bacterial pathogenesis. Here, we train and compare six machine learning models, namely, Naive Bayes (NB), K-nearest neighbor (KNN), logistic regression (LR), random forest (RF), support vector machines (SVMs) and multilayer perceptron (MLP), for the identification of T4SEs using 10 types of selected features and 5-fold cross-validation. Our study shows that: (1) including different but complementary features generally enhance the predictive performance of T4SEs; (2) ensemble models, obtained by integrating individual single-feature models, exhibit a significantly improved predictive performance and (3) the 'majority voting strategy' led to a more stable and accurate classification performance when applied to predicting an ensemble learning model with distinct single features. We further developed a new method to effectively predict T4SEs, Bastion4 (Bacterial secretion effector predictor for T4SS), and we show our ensemble classifier clearly outperforms two recent prediction tools. In summary, we developed a state-of-the-art T4SE predictor by conducting a comprehensive performance evaluation of different machine learning algorithms along with a detailed analysis of single- and multi-feature selections. PMID- 29186296 TI - Adjuvant therapy in renal cell carcinoma: does higher risk for recurrence improve the chance for success? AB - The success of targeted therapies, including inhibitors of the vascular endothelial growth factor pathway or the mammalian target of rapamycin, in the treatment of metastatic renal cell carcinoma led to interest in testing their efficacy in the adjuvant setting. Results from the first trials are now available, with other studies due to report imminently. This review provides an overview of adjuvant targeted therapy in renal cell carcinoma, including interpretation of currently available conflicting data and future direction of research. We discuss the key differences between the completed targeted therapy adjuvant trials, and highlight the importance of accurately identifying patients who are likely to benefit from adjuvant treatment. We also consider reasons why blinded independent radiology review and treatment dose may prove critical for adjuvant treatment success. The implications of using disease-free survival as a surrogate end point for overall survival from the patient perspective and measurement of health benefit have recently been brought into focus and are discussed. Finally, we discuss how the ongoing adjuvant trials with targeted therapies and checkpoint inhibitors may improve our understanding and ability to prevent tumor recurrence after nephrectomy in the future. PMID- 29186298 TI - SimulaTE: simulating complex landscapes of transposable elements of populations. AB - Motivation: Estimating the abundance of transposable elements (TEs) in populations (or tissues) promises to answer many open research questions. However, progress is hampered by the lack of concordance between different approaches for TE identification and thus potentially unreliable results. Results: To address this problem, we developed SimulaTE a tool that generates TE landscapes for populations using a newly developed domain specific language (DSL). The simple syntax of our DSL allows for easily building even complex TE landscapes that have, for example, nested, truncated and highly diverged TE insertions. Reads may be simulated for the populations using different sequencing technologies (PacBio, Illumina paired-ends) and strategies (sequencing individuals and pooled populations). The comparison between the expected (i.e. simulated) and the observed results will guide researchers in finding the most suitable approach for a particular research question.

PMID- 29186299 TI - Within-plant variation in seed size and inflorescence fecundity is associated with epigenetic mosaicism in the shrub Lavandula latifolia (Lamiaceae). AB - Background and Aims: Sub-individual variation in traits of homologous structures has multiple ecological consequences for individuals and populations. Assessing the evolutionary significance of such effects requires an improved knowledge of the mechanisms underlying within-plant phenotypic heterogeneity. The hypothesis that continuous within-plant variation in some phenotypic traits can be associated with epigenetic mosaicism was examined. Methods: Fifteen individuals of the long-lived, evergreen Mediterranean shrub Lavandula latifolia were studied. Five widely spaced 'modules', each consisting of a single inflorescence plus all its subtending basal leaves, were collected from each shrub. Genomic DNA was extracted from leaf samples and genome-wide cytosine methylation determined by reversed phase high-performance liquid chromatography (HPLC) with spectrofluorimetric detection. The number and mean mass of seeds produced were determined for each inflorescence. An assessment was made of whether (1) leaves from different modules in the same plant differed significantly in global DNA cytosine methylation, and (2) mosaicism in cytosine methylation contributed to explain variation across modules in number and size of seeds. Key Results: Leaves from different modules in the same plant differed in global DNA cytosine methylation. The magnitude of epigenetic mosaicism was substantial, as the variance in DNA methylation among modules of the same shrub was greater than the variance between individuals. Number and mean mass of seeds produced by individual inflorescences varied within plants and were quadratically related to cytosine methylation of subtending leaves, with an optimum at an intermediate methylation level (approx. 25 %). Conclusions: The results support a causal link between global cytosine methylation of leaves in a module and the size and numbers of seeds produced by the associated inflorescence. It is proposed that variation in global DNA methylation within L. latifolia shrubs may result from the concerted action of plant sectoriality and differential exposure of different plant parts to some environmental factor(s) with a capacity to induce durable epigenetic changes.

AB - Resistant hypertension (RH) is a multifactorial disease associated with several target organ damage, such as microalbuminuria, left ventricular hypertrophy, and arterial stiffness. These subjects have high cardiovascular complications, especially when associated with diabetes condition. Sodium glucose cotransporter 2 (SGLT-2) inhibitors represent a new class of oral antidiabetic drugs that have shown positive effects in diabetics and even hypertensives subjects. Several studies demonstrated positive outcomes related to blood pressure levels, body weight, and glycemic control. Also found a reduction on microalbuminuria, cardiac and arterial remodeling process, and decrease in hospitalization care due heart failure. Despite these positive effects, the outcomes found for stroke were conflicted and tend neutral effect. Based on this, we sought to assess the pleiotropic effects of SGLT-2 inhibitors and the possible impact in RH subjects. In order to analyze the prospects of SGLT-2 inhibitors as a possible medication to complement the therapy manage of this high-risk class of patients. PMID- 29186297 TI - Noncoding RNAs in Cardiovascular Disease: Pathological Relevance and Emerging Role as Biomarkers and Therapeutics. AB - Noncoding RNAs (ncRNA) include a diverse range of functional RNA species microRNAs (miRNAs) and long noncoding RNAs (lncRNAs) being most studied in pathophysiology. Cardiovascular morbidity is associated with differential expression of myriad miRNAs; miR-21, miR-155, miR-126, miR-146a/b, miR-143/145, miR-223, and miR-221 are the top 9 most reported miRNAs in hypertension and atherosclerotic disease. A single miRNA may have hundreds of messenger RNA targets, which makes a full appreciation of the physiologic ramifications of such broad-ranging effects a challenge. miR-21 is the most prominent ncRNA associated with hypertension and atherosclerotic disease due to its role as a "mechano-miR", responding to arterial shear stresses. "Immuno-miRs", such as miR-155 and miR 223, affect cardiovascular disease (CVD) via regulation of hematopoietic cell differentiation, chemotaxis, and activation in response to many pro-atherogenic stimuli. "Myo-miRs", such as miR-1 and miR-133, affect cardiac muscle plasticity and remodeling in response to mechanical overload. This in-depth review analyzes observational and experimental reports of ncRNAs in CVD, including future applications of ncRNA-based strategies in diagnosis, prediction (e.g., survival and response to small molecule therapy), and biologic therapy.

AB - Mental illness is increasingly recognized as both a significant cost to society and a significant area of opportunity for biological breakthrough. As -omics and imaging technologies enable researchers to probe molecular and physiological underpinnings of multiple diseases, opportunities arise to explore the biological basis for behavioral health and disease. From individual investigators to large international consortia, researchers have generated rich data sets in the area of mental health, including genomic, transcriptomic, metabolomic, proteomic, clinical and imaging resources. General data repositories such as the Gene Expression Omnibus (GEO) and Database of Genotypes and Phenotypes (dbGaP) and mental health (MH)-specific initiatives, such as the Psychiatric Genomics Consortium, MH Research Network and PsychENCODE represent a wealth of information yet to be gleaned. At the same time, novel approaches to integrate and analyze data sets are enabling important discoveries in the area of mental and behavioral health. This review will discuss and catalog into an organizing framework the increasingly diverse set of MH data resources available, using schizophrenia as a focus area, and will describe novel and integrative approaches to molecular biomarker discovery that make use of mental health data. PMID- 29186304 TI - Construction of a hierarchical gene regulatory network centered around a transcription factor. AB - We have modified a multitude of transcription factors (TFs) in numerous plant species and some animal species, and obtained transgenic lines that exhibit phenotypic alterations. Whenever we observe phenotypic changes in a TF's transgenic lines, we are always eager to identify its target genes, collaborative regulators and even upstream high hierarchical regulators. This issue can be addressed by establishing a multilayered hierarchical gene regulatory network (ML hGRN) centered around a given TF. In this article, a practical approach for constructing an ML-hGRN centered on a TF using a combined approach of top-down and bottom-up network construction methods is described. Strategies for constructing ML-hGRNs are vitally important, as these networks provide key information to advance our understanding of how biological processes are regulated. PMID- 29186303 TI - Lack of Association Between Maternal or Neonatal Vitamin D Status and Risk of Childhood Type 1 Diabetes: A Scandinavian Case-Cohort Study. AB - Studies on vitamin D status during pregnancy and risk of type 1 diabetes mellitus (T1D) lack consistency and are limited by small sample sizes or single measures of 25-hydroxyvitamin D (25(OH)D). We investigated whether average maternal 25(OH)D plasma concentrations during pregnancy are associated with risk of childhood T1D. In a case-cohort design, we identified 459 children with T1D and a random sample (n = 1,561) from the Danish National Birth Cohort (n = 97,127) and Norwegian Mother and Child Cohort Study (n = 113,053). Participants were born between 1996 and 2009. The primary exposure was the estimated average 25(OH)D concentration, based on serial samples from the first trimester until delivery and on umbilical cord plasma. We estimated hazard ratios using weighted Cox regression adjusting for multiple confounders. The adjusted hazard ratio for T1D per 10-nmol/L increase in the estimated average 25(OH)D concentration was 1.00 (95% confidence interval: 0.90, 1.10). Results were consistent in both cohorts, in multiple sensitivity analyses, and when we analyzed mid-pregnancy or cord blood separately. In conclusion, our large study demonstrated that normal variation in maternal or neonatal 25(OH)D is unlikely to have a clinically important effect on risk of childhood T1D. PMID- 29186305 TI - Systems Bioinformatics: increasing precision of computational diagnostics and therapeutics through network-based approaches. AB - Systems Bioinformatics is a relatively new approach, which lies in the intersection of systems biology and classical bioinformatics. It focuses on integrating information across different levels using a bottom-up approach as in systems biology with a data-driven top-down approach as in bioinformatics. The advent of omics technologies has provided the stepping-stone for the emergence of Systems Bioinformatics. These technologies provide a spectrum of information ranging from genomics, transcriptomics and proteomics to epigenomics, pharmacogenomics, metagenomics and metabolomics. Systems Bioinformatics is the framework in which systems approaches are applied to such data, setting the level of resolution as well as the boundary of the system of interest and studying the emerging properties of the system as a whole rather than the sum of the properties derived from the system's individual components. A key approach in Systems Bioinformatics is the construction of multiple networks representing each level of the omics spectrum and their integration in a layered network that exchanges information within and between layers. Here, we provide evidence on how Systems Bioinformatics enhances computational therapeutics and diagnostics, hence paving the way to precision medicine. The aim of this review is to familiarize the reader with the emerging field of Systems Bioinformatics and to provide a comprehensive overview of its current state-of-the-art methods and technologies. Moreover, we provide examples of success stories and case studies that utilize such methods and tools to significantly advance research in the fields of systems biology and systems medicine. PMID- 29186301 TI - Toenail Manganese: A Sensitive and Specific Biomarker of Exposure to Manganese in Career Welders. AB - Manganese (Mn) is an essential trace metal. It is also a component of welding fume. Chronic inhalation of manganese from welding fume has been associated with decreased neurological function. Currently, there is not a universally recognized biomarker for Mn exposure; however, hair and toenails have shown promise. In a cohort of 45 male welders and 35 age-matched factory control subjects, we assessed the sensitivity and specificity of toenail Mn to distinguish occupationally exposed subjects from unexposed controls. Further we examined the exposure time window that best correlates with the proposed biomarker, and investigated if non-occupational exposure factors impacted toenail Mn concentrations. Toenail clippings were analyzed for Mn using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Exposure to respirable Mn-containing particles (<4 um) was estimated using an exposure model that combines personal air monitoring, work history information, and dietary intake to estimate an individual's exposure to Mn from inhalation of welding fume. We assessed the group differences in toenail concentrations using a Student's t-test between welders and control subjects and performed a receiver operating characteristic (ROC) curve analysis to identify a threshold in toenail concentration that has the highest sensitivity and specificity in distinguishing welders from control subjects. Additionally, we performed mixed-model regressions to investigate the association between different exposure windows and toenail Mn concentrations. We observed that toenail Mn concentrations were significantly elevated among welders compared to control subjects (6.87 +/- 2.56 versus 2.70 +/- 1.70 ug g-1; P < 0.001). Our results show that using a toenail Mn concentration of 4.14 ug g-1 as cutoff allows for discriminating between controls and welders with 91% specificity and 94% sensitivity [area under curve (AUC) = 0.98]. Additionally, we found that a threshold of 4.66 ug g-1 toenail Mn concentration enables a 90% sensitive and 90% specific discrimination (AUC = 0.96) between subjects with average exposure above or below the American Conference of Governmental Industrial Hygienist (ACGIH) Threshold Limit Value (TLV) of 0.02 mg m-3 during the exposure window of 7-12 months prior to the nail being clipped. Investigating which exposure window was best reflected by toenail Mn reproduced the result from another study of toenail Mn being significantly (P < 0.001) associated with exposure 7-12 months prior to the nail being clipped. Lastly, we found that dietary intake, body mass index, age, smoking status, and ethnicity had no significant effect on toenail Mn concentrations. Our results suggest that toenail Mn is a sensitive, specific, and easy-to-acquire biomarker of Mn exposure, which is feasible to be used in an industrial welder population.

PMID- 29186307 TI - Ultrastructure and development of non-contiguous stomatal clusters and helicocytic patterning in Begonia. AB - Background and Aims: Helicocytic stomata are characterized by an inward spiral of mesogenous cells surrounding a central stomatal pore. They represent a relatively rare feature that occurs in some drought-tolerant angiosperm species. In some Begonia species with thick leaves, the stomata are not only helicocytic but also clustered into groups that are spaced apart by at least one cell. This paper presents a detailed ontogenetic study of this characteristic non-contiguous stomatal patterning in a developmental and phylogenetic context. Methods: Light microscopy and both scanning and transmission electron microscopy were used to examine stomatal development in several species of Begonia. Published reports of stomatal development in Begonia and other angiosperms were reviewed to provide a comprehensive discussion of the evolution of stomatal patterning. Key Results: Helicocytic stomata develop from meristemoids that undergo a series of oriented asymmetric divisions to produce a spiral of mesogene stomatal lineage ground cells (SLGCs) surrounding a stoma. A clear developmental similarity between anisocytic and helicocytic stomata is positively correlated with the number of iterations of amplifying divisions that result in SLGCs. Stomatal clusters develop from asymmetric divisions in neighbouring SLGCs. Within each cluster, non contiguous spacing of meristemoids is maintained by asymmetric divisions oriented away from each developing meristemoid. Conclusions: Formation of non-contiguous stomatal clusters in Begonia relies on two primary developmental factors in the epidermis: an inwardly spiralling series of amplifying divisions that result in helicocytic stomata, and the development of a variable number of meristemoids from neighbouring SLGCs within each cluster. Optimization of these features on an angiosperm phylogeny indicates that the occurrence of amplifying divisions could be pre-adaptive for these factors. Both factors have been thoroughly studied in terms of developmental genetics in Arabidopsis, suggesting gene orthologues that could be implicated in Begonia stomatal patterning.

PMID- 29186308 TI - Predicting Forearm Physical Exposures During Computer Work Using Self-Reports, Software-Recorded Computer Usage Patterns, and Anthropometric and Workstation Measurements. AB - Objectives: Alternative techniques to assess physical exposures, such as prediction models, could facilitate more efficient epidemiological assessments in future large cohort studies examining physical exposures in relation to work related musculoskeletal symptoms. The aim of this study was to evaluate two types of models that predict arm-wrist-hand physical exposures (i.e. muscle activity, wrist postures and kinematics, and keyboard and mouse forces) during computer use, which only differed with respect to the candidate predicting variables; (i) a full set of predicting variables, including self-reported factors, software recorded computer usage patterns, and worksite measurements of anthropometrics and workstation set-up (full models); and (ii) a practical set of predicting variables, only including the self-reported factors and software-recorded computer usage patterns, that are relatively easy to assess (practical models). Methods: Prediction models were build using data from a field study among 117 office workers who were symptom-free at the time of measurement. Arm-wrist-hand physical exposures were measured for approximately two hours while workers performed their own computer work. Each worker's anthropometry and workstation set-up were measured by an experimenter, computer usage patterns were recorded using software and self-reported factors (including individual factors, job characteristics, computer work behaviours, psychosocial factors, workstation set up characteristics, and leisure-time activities) were collected by an online questionnaire. We determined the predictive quality of the models in terms of R2 and root mean squared (RMS) values and exposure classification agreement to low-, medium-, and high-exposure categories (in the practical model only). Results: The full models had R2 values that ranged from 0.16 to 0.80, whereas for the practical models values ranged from 0.05 to 0.43. Interquartile ranges were not that different for the two models, indicating that only for some physical exposures the full models performed better. Relative RMS errors ranged between 5% and 19% for the full models, and between 10% and 19% for the practical model. When the predicted physical exposures were classified into low, medium, and high, classification agreement ranged from 26% to 71%. Conclusion: The full prediction models, based on self-reported factors, software-recorded computer usage patterns, and additional measurements of anthropometrics and workstation set-up, show a better predictive quality as compared to the practical models based on self-reported factors and recorded computer usage patterns only. However, predictive quality varied largely across different arm-wrist-hand exposure parameters. Future exploration of the relation between predicted physical exposure and symptoms is therefore only recommended for physical exposures that can be reasonably well predicted.

PMID- 29186311 TI - Unequal Exposure or Unequal Vulnerability? Contributions of Neighborhood Conditions and Cardiovascular Risk Factors to Socioeconomic Inequality in Incident Cardiovascular Disease in the Multi-Ethnic Study of Atherosclerosis. AB - Risk factors can drive socioeconomic inequalities in cardiovascular disease (CVD) through differential exposure and differential vulnerability. In this paper, we show how econometric decomposition directly enables simultaneous, policy-oriented assessment of these 2 mechanisms. We specifically estimate contributions of neighborhood environment and proximal risk factors to socioeconomic inequality in CVD incidence via these mechanisms. We followed 5,608 participants in the Multi Ethnic Study of Atherosclerosis (2000-2012) to their first CVD event (median length of follow-up, 12.2 years). We used a summary measure of baseline socioeconomic position (SEP). Covariates included baseline demographics, neighborhood characteristics, and psychosocial, behavioral, and biomedical risk factors. Using Poisson models, we decomposed the difference (inequality) in incidence rates between low- and high-SEP groups into contributions of 1) differences in covariate means (differential exposure) and 2) differences in CVD risk associated with covariates (differential vulnerability). Notwithstanding large uncertainty in neighborhood estimates, our analysis suggested that differential exposure to poorer neighborhood socioeconomic conditions, adverse social environment, diabetes, and hypertension accounted for most of the inequality. Psychosocial and behavioral contributions were negligible. Further, neighborhood SEP, female sex, and white race were more strongly associated with CVD among low-SEP (vs. high-SEP) participants. These differentials in vulnerability also accounted for nontrivial portions of the inequality and could have important implications for intervention. PMID- 29186313 TI - The Latent Structure and Test-Retest Stability of Connected Language Measures in the Wisconsin Registry for Alzheimer's Prevention (WRAP). AB - Introduction: While it is well known that discourse-related language functions are impaired in the dementia phase of Alzheimer's Disease (AD), the presymptomatic temporal course of discourse dysfunction are not known earlier in the course of AD. To conduct discourse-related studies in this phase of AD, validated psychometric instruments are needed. This study investigates the latent structure, validity, and test-retest stability of discourse measures in a late middle-aged normative group who are relatively free from sporadic AD risk factors. Methods: Using a normative sample of 399 participants (mean age = 61), exploratory factor analyses (EFA) and confirmatory factor analyses (CFA) were conducted on 18 measures of connected language derived from picture descriptions. Factor invariance across sex and family history and longitudinal test-retest stability measures were calculated. Results: The EFA revealed a four-factor solution, consisting of semantic, syntax, fluency, and lexical constructs. The CFA model substantiated the structure, and factors were invariant across sex and parental history of AD status. Test-retest stability measures were within acceptable ranges. Conclusions: Results confirm a factor structure that is invariant across sex and parental AD history. The factor structure could be useful in similar cohorts designed to detect early language decline in investigations of preclinical or clinical AD or as outcome measures in clinical prevention trials. PMID- 29186314 TI - Reproducibility of Retinal Microvascular Traits Decoded by the Singapore I Vessel Assessment Software Across the Human Age Range. AB - BACKGROUND: Retinal microvascular traits predict adverse health outcomes. The Singapore I Vessel Assessment (SIVA) software improved automated postprocessing of retinal photographs. In addition to microvessel caliber, it generates measures of arteriolar and venular geometry. Few studies addressed the reproducibility of SIVA measurements across a wide age range. METHODS: In the current study, 2 blinded graders read images obtained by nonmydriatic retinal photography twice in 20 11-year-old children, born prematurely (n = 10) or at term (n = 10) and in 60 adults (age range, 18.9-86.1 years). RESULTS: Former preterm compared with term children had lower microvessel diameter and disorganized vessel geometry with no differences in intraobserver and interobserver variability. Among adults, microvessel caliber decreased with age and blood pressure and arteriolar geometry was inversely correlated with female sex and age. Intraobserver differences estimated by the Bland-Altman method did not reach significance for any measurement. Across measurements, median reproducibility (RM) expressed as percent of the average trait value was 8.8% in children (median intraclass correlation coefficient [ICC], 0.94) and 8.0% (0.97) in adults. Likewise, interobserver differences did not reach significance with RM (ICC) of 10.6% (0.85) in children and 10.4% (0.93) in adults. Reproducibility was best for microvessel caliber (intraobserver/interobserver RM, 4.7%/6.0%; ICC, 0.98/0.96), worst for venular geometry (17.0%/18.8%; 0.93/0.84), and intermediate for arteriolar geometry (10.9%/14.9%; 0.95/0.86). CONCLUSIONS: SIVA produces repeatable measures of the retinal microvasculature in former preterm and term children and in adults, thereby proving its usability from childhood to old age. PMID- 29186315 TI - Resources and tools for the high-throughput, multi-omic study of intestinal microbiota. AB - The human gut microbiome impacts several aspects of human health and disease, including digestion, drug metabolism and the propensity to develop various inflammatory, autoimmune and metabolic diseases. Many of the molecular processes that play a role in the activity and dynamics of the microbiota go beyond species and genic composition and thus, their understanding requires advanced bioinformatics support. This article aims to provide an up-to-date view of the resources and software tools that are being developed and used in human gut microbiome research, in particular data integration and systems-level analysis efforts. These efforts demonstrate the power of standardized and reproducible computational workflows for integrating and analysing varied omics data and gaining deeper insights into microbe community structure and function as well as host-microbe interactions. PMID- 29186316 TI - A review of databases predicting the effects of SNPs in miRNA genes or miRNA binding sites. AB - Modern precision medicine comprises the knowledge and understanding of individual differences in the genomic sequence of patients to provide tailor-made treatments. Regularly, such variants are considered in coding regions only, and their effects are predicted based on their impact on the amino acid sequence of expressed proteins. However, assessing the effects of variants in noncoding elements, in particular microRNAs (miRNAs) and their binding sites, is important as well, as a single miRNA can influence the expression patterns of many genes at the same time. To analyze the effects of variants in miRNAs and their target sites, several databases storing variant impact predictions have been published. In this review, we will compare the core functionalities and features of these databases and discuss the importance of up-to-date data resources in the context of web applications. Finally, we will outline some recommendations for future developments in the field. PMID- 29186317 TI - Computational profiling of the gut-brain axis: microflora dysbiosis insights to neurological disorders. AB - Almost 2500 years after Hippocrates' observations on health and its direct association to the gastrointestinal tract, a paradigm shift has recently occurred, making the gut and its symbionts (bacteria, fungi, archaea and viruses) a point of convergence for studies. It is nowadays well established that the gut microflora's compositional diversity regulates via its genes (the microbiome) the host's health and provides preliminary insights into disease progression and regulation. The microbiome's involvement is evident in immunological and physiological studies that link changes in its biodiversity to its contributions to the host's phenotype but also in neurological investigations, substantiating the aptly named gut-brain axis. The definitive mechanisms of this last bidirectional interaction will be our main focus because it presents researchers with a new conundrum. In this review, we prospect current literature for computational analysis methodologies that accommodate the need for better understanding of the microbiome-gut-brain interactions and neurological disorder onset and progression, through cross-disciplinary systems biology applications. We will present bioinformatics tools used in exploring these synergies that help build and interpret microbial 16S ribosomal RNA data sets, produced by shotgun and high-throughput sequencing of healthy and neurological disorder samples stored in biological databases. These approaches provide alternative means for researchers to form hypotheses to their inquests faster, cheaper and swith precision. The goal of these studies relies on the integration of combined metagenomics and metabolomics assessments. An accurate characterization of the microbiome and its functionality can support new diagnostic, prognostic and therapeutic strategies for neurological disorders, customized for each individual host.

PMID- 29186319 TI - OV21/PETROC: a randomized Gynecologic Cancer Intergroup phase II study of intraperitoneal versus intravenous chemotherapy following neoadjuvant chemotherapy and optimal debulking surgery in epithelial ovarian cancer. AB - Background: The purpose of this multistage, adaptively, designed randomized phase II study was to evaluate the role of intraperitoneal (i.p.) chemotherapy following neoadjuvant chemotherapy (NACT) and optimal debulking surgery in women with epithelial ovarian cancer (EOC). Patients and methods: We carried out a multicenter, two-stage, phase II trial. Eligible patients with stage IIB-IVA EOC treated with platinum-based intravenous (i.v.) NACT followed by optimal (<1 cm) debulking surgery were randomized to one of the three treatment arms: (i) i.v. carboplatin/paclitaxel, (ii) i.p. cisplatin plus i.v./i.p. paclitaxel, or (iii) i.p. carboplatin plus i.v./i.p. paclitaxel. The primary end point was 9-month progressive disease rate (PD9). Secondary end points included progression-free survival (PFS), overall survival (OS), toxicity, and quality of life (QOL). Results: Between 2009 and 2015, 275 patients were randomized; i.p. cisplatin containing arm did not progress beyond the first stage of the study after failing to meet the pre-set superiority rule. The final analysis compared i.v. carboplatin/paclitaxel (n = 101) with i.p. carboplatin, i.v./i.p. paclitaxel (n = 102). The intention to treat PD9 was lower in the i.p. carboplatin arm compared with the i.v. carboplatin arm: 24.5% (95% CI 16.2% to 32.9%) versus 38.6% (95% CI 29.1% to 48.1%) P = 0.065. The study was underpowered to detect differences in PFS: HR PFS 0.82 (95% CI 0.57-1.17); P = 0.27 and OS HR 0.80 (95% CI 0.47-1.35) P = 0.40. The i.p. carboplatin-based regimen was well tolerated with no reduction in QOL or increase in toxicity compared with i.v. administration alone. Conclusion: In women with stage IIIC or IVA EOC treated with NACT and optimal debulking surgery, i.p. carboplatin-based chemotherapy is well tolerated and associated with an improved PD9 compared with i.v. carboplatin-based chemotherapy.

AB - Motivation: The standard protocol for detecting variation in DNA is to map millions of short sequence reads to a known reference and find loci that differ. While this approach works well, it cannot be applied where the sample contains dense variants or is too distant from known references. De novo assembly or hybrid methods can recover genomic variation, but the cost of computation is often much higher. We developed a novel k-mer algorithm and software implementation, Kestrel, capable of characterizing densely packed SNPs and large indels without mapping, assembly or de Bruijn graphs. Results: When applied to mosaic penicillin binding protein (PBP) genes in Streptococcus pneumoniae, we found near perfect concordance with assembled contigs at a fraction of the CPU time. Multilocus sequence typing (MLST) with this approach was able to bypass de novo assemblies. Kestrel has a very low false-positive rate when applied to the whole genome, and while Kestrel identified many variants missed by other methods, limitations of a purely k-mer based approach affect overall sensitivity.

PMID- 29186320 TI - Declining Hepatitis C Virus (HCV) Incidence in Dutch Human Immunodeficiency Virus Positive Men Who Have Sex With Men After Unrestricted Access to HCV Therapy. AB - Background: Direct-acting antivirals (DAAa) cure hepatitis C virus (HCV) infections in 95% of infected patients. Modeling studies predict that universal HCV treatment will lead to a decrease in the incidence of new infections but real life data are lacking. The incidence of HCV among Dutch human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) has been high for >10 years. In 2015 DAAs became available to all Dutch HCV patients and resulted in a rapid treatment uptake in HIV-positive MSM. We assessed whether this uptake was followed by a decrease in the incidence of HCV infections. Methods: Two prospective studies of treatment for acute HCV infection enrolled patients in 17 Dutch HIV centers, having 76% of the total HIV-positive MSM population in care in the Netherlands. Patients were recruited in 2014 and 2016, the years before and after unrestricted DAA availability. We compared the HCV incidence in both years. Results: The incidence of acute HCV infection decreased from 93 infections during 8290 person-years of follow-up (PYFU) in 2014 (11.2/1000 PYFU; 95% confidence interval [CI], 9.1-13.7) to 49 during 8961 PYFU in 2016 (5.5/1000 PYFU; 4.1-7.2). The incidence rate ratio of 2016 compared with 2014 was 0.49 (95% CI, .35-.69). Simultaneously, a significant increase in the percentage positive syphilis (+2.2%) and gonorrhea (+2.8%) tests in HIV-positive MSM was observed at sexual health clinics across the Netherlands and contradicts a decrease in risk behavior as an alternative explanation. Conclusions: Unrestricted DAA availability in the Netherlands was followed by a 51% decrease in acute HCV infections among HIV positive MSM.

AB - Summary: To unlock the full potential of genome data and to enhance data interoperability and reusability of genome annotations we have developed SAPP, a Semantic Annotation Platform with Provenance. SAPP is designed as an infrastructure supporting FAIR de novo computational genomics but can also be used to process and analyze existing genome annotations. SAPP automatically predicts, tracks and stores structural and functional annotations and associated dataset- and element-wise provenance in a Linked Data format, thereby enabling information mining and retrieval with Semantic Web technologies. This greatly reduces the administrative burden of handling multiple analysis tools and versions thereof and facilitates multi-level large scale comparative analysis.

PMID- 29186323 TI - An attention-based BiLSTM-CRF approach to document-level chemical named entity recognition. AB - Motivation: In biomedical research, chemical is an important class of entities, and chemical named entity recognition (NER) is an important task in the field of biomedical information extraction. However, most popular chemical NER methods are based on traditional machine learning and their performances are heavily dependent on the feature engineering. Moreover, these methods are sentence-level ones which have the tagging inconsistency problem. Results: In this paper, we propose a neural network approach, i.e. attention-based bidirectional Long Short Term Memory with a conditional random field layer (Att-BiLSTM-CRF), to document level chemical NER. The approach leverages document-level global information obtained by attention mechanism to enforce tagging consistency across multiple instances of the same token in a document. It achieves better performances with little feature engineering than other state-of-the-art methods on the BioCreative IV chemical compound and drug name recognition (CHEMDNER) corpus and the BioCreative V chemical-disease relation (CDR) task corpus (the F-scores of 91.14 and 92.57%, respectively).

PMID- 29186324 TI - Robust inference of population structure from next-generation sequencing data with systematic differences in sequencing. AB - Motivation: Inferring population structure is important for both population genetics and genetic epidemiology. Principal components analysis (PCA) has been effective in ascertaining population structure with array genotype data but can be difficult to use with sequencing data, especially when low depth leads to uncertainty in called genotypes. Because PCA is sensitive to differences in variability, PCA using sequencing data can result in components that correspond to differences in sequencing quality (read depth and error rate), rather than differences in population structure. We demonstrate that even existing methods for PCA specifically designed for sequencing data can still yield biased conclusions when used with data having sequencing properties that are systematically different across different groups of samples (i.e. sequencing groups). This situation can arise in population genetics when combining sequencing data from different studies, or in genetic epidemiology when using historical controls such as samples from the 1000 Genomes Project. Results: To allow inference on population structure using PCA in these situations, we provide an approach that is based on using sequencing reads directly without calling genotypes. Our approach is to adjust the data from different sequencing groups to have the same read depth and error rate so that PCA does not generate spurious components representing sequencing quality. To accomplish this, we have developed a subsampling procedure to match the depth distributions in different sequencing groups, and a read-flipping procedure to match the error rates. We average over subsamples and read flips to minimize loss of information. We demonstrate the utility of our approach using two datasets from 1000 Genomes, and further evaluate it using simulation studies.

PMID- 29186325 TI - glactools: a command-line toolset for the management of genotype likelihoods and allele counts. AB - Motivation: Research projects involving population genomics routinely need to store genotyping information, population allele counts, combine files from different samples, query the data and export it to various formats. This is often done using bespoke in-house scripts, which cannot be easily adapted to new projects and seldom constitute reproducible workflows. Results: We introduce glactools, a set of command-line utilities that can import data from genotypes or population-wide allele counts into an intermediate representation, compute various operations on it and export the data to several file formats used by population genetics software. This intermediate format can take two forms, one to store per-individual genotype likelihoods and a second for allele counts from one or more individuals. glactools allows users to perform operations such as intersecting datasets, merging individuals into populations, creating subsets, perform queries (e.g. return sites where a given population does not share an allele with a second one) and compute summary statistics to answer biologically relevant questions. Availability and implementation: glactools is freely available for use under the GPL. It requires a C ++ compiler and the htslib library.

PMID- 29186327 TI - Efficiently counting all orbits of graphlets of any order in a graph using autogenerated equations. AB - Motivation: Graphlets are a useful tool to determine a graph's small-scale structure. Finding them is exponentially hard with respect to the number of nodes in each graphlet. Therefore, equations can be used to reduce the size of graphlets that need to be enumerated to calculate the number of each graphlet touching each node. Hocevar and Demsar first introduced such equations, which were derived manually, and an algorithm that uses them, but only graphlets with four or five nodes can be counted this way. Results: We present a new algorithm for orbit counting, which is applicable to graphlets of any order. This algorithm uses a tree structure to simplify finding orbits, and stabilizers and symmetry breaking constraints to ensure correctness. This method gives a significant speedup compared to a brute force counting method and can count orbits beyond the capacity of other available tools. Availability and implementation: An implementation of the algorithm can be found at https://github.com/biointec/jesse. Contact: pieter.audenaert@ugent.be. PMID- 29186328 TI - Meta-analytic principal component analysis in integrative omics application. AB - Motivation: With the prevalent usage of microarray and massively parallel sequencing, numerous high-throughput omics datasets have become available in the public domain. Integrating abundant information among omics datasets is critical to elucidate biological mechanisms. Due to the high-dimensional nature of the data, methods such as principal component analysis (PCA) have been widely applied, aiming at effective dimension reduction and exploratory visualization. Results: In this article, we combine multiple omics datasets of identical or similar biological hypothesis and introduce two variations of meta-analytic framework of PCA, namely MetaPCA. Regularization is further incorporated to facilitate sparse feature selection in MetaPCA. We apply MetaPCA and sparse MetaPCA to simulations, three transcriptomic meta-analysis studies in yeast cell cycle, prostate cancer, mouse metabolism and a TCGA pan-cancer methylation study. The result shows improved accuracy, robustness and exploratory visualization of the proposed framework. Availability and implementation: An R package MetaPCA is available online.

PMID- 29186329 TI - ASElux: an ultra-fast and accurate allelic reads counter. AB - Motivation: Mapping bias causes preferential alignment to the reference allele, forming a major obstacle in allele-specific expression (ASE) analysis. The existing methods, such as simulation and SNP-aware alignment, are either inaccurate or relatively slow. To fast and accurately count allelic reads for ASE analysis, we developed a novel approach, ASElux, which utilizes the personal SNP information and counts allelic reads directly from unmapped RNA-sequence (RNA seq) data. ASElux significantly reduces runtime by disregarding reads outside single nucleotide polymorphisms (SNPs) during the alignment. Results: When compared to other tools on simulated and experimental data, ASElux achieves a higher accuracy on ASE estimation than non-SNP-aware aligners and requires a much shorter time than the benchmark SNP-aware aligner, GSNAP with just a slight loss in performance. ASElux can process 40 million read-pairs from an RNA-sequence (RNA-seq) sample and count allelic reads within 10 min, which is comparable to directly counting the allelic reads from alignments based on other tools. Furthermore, processing an RNA-seq sample using ASElux in conjunction with a general aligner, such as STAR, is more accurate and still ~4* faster than STAR + WASP, and ~33* faster than the lead SNP-aware aligner, GSNAP, making ASElux ideal for ASE analysis of large-scale transcriptomic studies. We applied ASElux to 273 lung RNA-seq samples from GTEx and identified a splice-QTL rs11078928 in lung which explains the mechanism underlying an asthma GWAS SNP rs11078927. Thus, our analysis demonstrated ASE as a highly powerful complementary tool to cis expression quantitative trait locus (eQTL) analysis.

PMID- 29186330 TI - Utilization of a clinical microbiology service at a Cambodian paediatric hospital and its impact on appropriate antimicrobial prescribing. AB - Background: Antimicrobial resistance threatens human health worldwide. Antimicrobial misuse is a major driver of resistance. Promoting appropriate antimicrobial use requires an understanding of how clinical microbiology services are utilized, particularly in resource-limited settings. Objectives: To assess the appropriateness of antimicrobial prescribing and the factors affecting utilization of the established clinical microbiology service (CMS). The CMS comprises the microbiology laboratory, clinical microbiologists (infection doctors) and antimicrobial treatment guidelines. Methods: This mixed-methods study was conducted at a non-governmental Cambodian paediatric hospital. Empirical and post-culture antimicrobial prescriptions were reviewed from medical records. The random sample included 10 outpatients per week in 2016 (retrospective) and 20 inpatients per week for 4 weeks in the medical, neonatal and intensive care wards (prospective). Post-culture prescriptions were assessed in patients with positive blood and cerebrospinal fluid cultures from 1 January 2014 to 31 December 2016. Focus group discussions and semi-structured interviews with clinicians explored barriers and facilitators to use of the CMS. Results: Only 31% of outpatients were prescribed empirical antimicrobials. Post-culture prescriptions (394/443, 89%) were more likely to be appropriate than empirical prescriptions (447/535, 84%), based on treatment guidelines, microbiology advice and antimicrobial susceptibility test results (P = 0.015). Being comprehensive, accessible and trusted enabled CMS utilization. Clinical microbiologists provided a crucial human interface between the CMS and physicians. The main barriers were a strong clinical hierarchy and occasional communication difficulties. Conclusions: Antimicrobial prescribing in this hospital was largely appropriate. A culturally appropriate human interface linking the laboratory and physicians is essential in providing effective microbiology services and ensuring appropriate antimicrobial prescribing in resource-limited settings.

AB - Motivation: During the past decade, big data have become a major tool in scientific endeavors. Although statistical methods and algorithms are well-suited for analyzing and summarizing enormous amounts of data, the results do not allow for a visual inspection of the entire data. Current scientific software, including R packages and Python libraries such as ggplot2, matplotlib and plot.ly, do not support interactive visualizations of datasets exceeding 100 000 data points on the web. Other solutions enable the web-based visualization of big data only through data reduction or statistical representations. However, recent hardware developments, especially advancements in graphical processing units, allow for the rendering of millions of data points on a wide range of consumer hardware such as laptops, tablets and mobile phones. Similar to the challenges and opportunities brought to virtually every scientific field by big data, both the visualization of and interaction with copious amounts of data are both demanding and hold great promise. Results: Here we present FUn, a framework consisting of a client (Faerun) and server (Underdark) module, facilitating the creation of web-based, interactive 3D visualizations of large datasets, enabling record level visual inspection. We also introduce a reference implementation providing access to SureChEMBL, a database containing patent information on more than 17 million chemical compounds.

PMID- 29186331 TI - DDR: efficient computational method to predict drug-target interactions using graph mining and machine learning approaches. AB - Motivation: Finding computationally drug-target interactions (DTIs) is a convenient strategy to identify new DTIs at low cost with reasonable accuracy. However, the current DTI prediction methods suffer the high false positive prediction rate. Results: We developed DDR, a novel method that improves the DTI prediction accuracy. DDR is based on the use of a heterogeneous graph that contains known DTIs with multiple similarities between drugs and multiple similarities between target proteins. DDR applies non-linear similarity fusion method to combine different similarities. Before fusion, DDR performs a pre processing step where a subset of similarities is selected in a heuristic process to obtain an optimized combination of similarities. Then, DDR applies a random forest model using different graph-based features extracted from the DTI heterogeneous graph. Using 5-repeats of 10-fold cross-validation, three testing setups, and the weighted average of area under the precision-recall curve (AUPR) scores, we show that DDR significantly reduces the AUPR score error relative to the next best start-of-the-art method for predicting DTIs by 34% when the drugs are new, by 23% when targets are new and by 34% when the drugs and the targets are known but not all DTIs between them are not known. Using independent sources of evidence, we verify as correct 22 out of the top 25 DDR novel predictions. This suggests that DDR can be used as an efficient method to identify correct DTIs.

PMID- 29186334 TI - Phenotypic stability and plasticity in GMP-derived cells as determined by their underlying regulatory network. AB - Motivation: Blood cell formation has been recognized as a suitable system to study celular differentiation mainly because of its experimental accessibility, and because it shows characteristics such as hierarchical and gradual bifurcated patterns of commitment, which are present in several developmental processes. Although hematopoiesis has been extensively studied and there is a wealth of molecular and cellular data about it, it is not clear how the underlying molecular regulatory networks define or restrict cellular differentiation processes. Here, we infer the molecular regulatory network that controls the differentiation of a blood cell subpopulation derived from the granulocyte monocyte precursor (GMP), comprising monocytes, neutrophils, eosinophils, basophils and mast cells. Results: We integrate published qualitative experimental data into a model to describe temporal expression patterns observed in GMP-derived cells. The model is implemented as a Boolean network, and its dynamical behavior is studied. Steady states of the network can be clearly identified with the expression profiles of monocytes, mast cells, neutrophils, basophils, and eosinophils, under wild-type and mutant backgrounds.

AB - : RNA-protein interactions occur in many biological processes. To understand the mechanism of these interactions one needs to know three-dimensional (3D) structures of RNA-protein complexes. 3dRPC is an algorithm for prediction of 3D RNA-protein complex structures and consists of a docking algorithm RPDOCK and a scoring function 3dRPC-Score. RPDOCK is used to sample possible complex conformations of an RNA and a protein by calculating the geometric and electrostatic complementarities and stacking interactions at the RNA-protein interface according to the features of atom packing of the interface. 3dRPC-Score is a knowledge-based potential that uses the conformations of nucleotide-amino acid pairs as statistical variables and that is used to choose the near-native complex-conformations obtained from the docking method above. Recently, we built a web server for 3dRPC. The users can easily use 3dRPC without installing it locally. RNA and protein structures in PDB (Protein Data Bank) format are the only needed input files. It can also incorporate the information of interface residues or residue-pairs obtained from experiments or theoretical predictions to improve the prediction.

PMID- 29186335 TI - The OncoPPi Portal: an integrative resource to explore and prioritize protein protein interactions for cancer target discovery. AB - Motivation: As cancer genomics initiatives move toward comprehensive identification of genetic alterations in cancer, attention is now turning to understanding how interactions among these genes lead to the acquisition of tumor hallmarks. Emerging pharmacological and clinical data suggest a highly promising role of cancer-specific protein-protein interactions (PPIs) as druggable cancer targets. However, large-scale experimental identification of cancer-related PPIs remains challenging, and currently available resources to explore oncogenic PPI networks are limited. Results: Recently, we have developed a PPI high-throughput screening platform to detect PPIs between cancer-associated proteins in the context of cancer cells. Here, we present the OncoPPi Portal, an interactive web resource that allows investigators to access, manipulate and interpret a high quality cancer-focused network of PPIs experimentally detected in cancer cell lines. To facilitate prioritization of PPIs for further biological studies, this resource combines network connectivity analysis, mutual exclusivity analysis of genomic alterations, cellular co-localization of interacting proteins and domain domain interactions. Estimates of PPI essentiality allow users to evaluate the functional impact of PPI disruption on cancer cell proliferation. Furthermore, connecting the OncoPPi network with the approved drugs and compounds in clinical trials enables discovery of new tumor dependencies to inform strategies to interrogate undruggable targets like tumor suppressors. The OncoPPi Portal serves as a resource for the cancer research community to facilitate discovery of cancer targets and therapeutic development.

AB - Summary: Studying the controllability of biomolecular networks can result in profound knowledge about molecular biological systems. However, there is no comprehensive and easy-to-use platform for analyzing controllability of biomolecular networks although various algorithms for analyzing complex network controllability have been proposed recently. In this application note, we develop the CytoCtrlAnalyser which is a Cytoscape app to provide a comprehensive platform for analyzing controllability of biomolecular networks. Nine algorithms have been integrated in CytoCtrlAnalyser. With network topologies and customized control settings imported into CytoCtrlAnalyser, users can identify the steering nodes which should be actuated by input control signals for achieving different control objectives as well as investigate the importance of nodes from different perspectives in the controllability of networks.

AB - Summary: Following the type II CRISPR-Cas9 system, type V CRISPR-Cpf1 endonucleases have been found to be applicable for genome editing in various organisms in vivo. However, there are as yet no web-based tools capable of optimally selecting guide RNAs (gRNAs) among all possible genome-wide target sites. Here, we present Cpf1-Database, a genome-wide gRNA library design tool for LbCpf1 and AsCpf1, which have DNA recognition sequences of 5'-TTTN-3' at the 5' ends of target sites. Cpf1-Database provides a sophisticated but simple way to design gRNAs for AsCpf1 nucleases on the genome scale.

PMID- 29186340 TI - Semi-supervised network inference using simulated gene expression dynamics. AB - Motivation: Inferring the structure of gene regulatory networks from high throughput datasets remains an important and unsolved problem. Current methods are hampered by problems such as noise, low sample size, and incomplete characterizations of regulatory dynamics, leading to networks with missing and anomalous links. Integration of prior network information (e.g. from pathway databases) has the potential to improve reconstructions. Results: We developed a semi-supervised network reconstruction algorithm that enables the synthesis of information from partially known networks with time course gene expression data. We adapted partial least square-variable importance in projection (VIP) for time course data and used reference networks to simulate expression data from which null distributions of VIP scores are generated and used to estimate edge probabilities for input expression data. By using simulated dynamics to generate reference distributions, this approach incorporates previously known regulatory relationships and links the network to the dynamics to form a semi-supervised approach that discovers novel and anomalous connections. We applied this approach to data from a sleep deprivation study with KEGG pathways treated as prior networks, as well as to synthetic data from several DREAM challenges, and find that it is able to recover many of the true edges and identify errors in these networks, suggesting its ability to derive posterior networks that accurately reflect gene expression dynamics.

PMID- 29186342 TI - Linking Metabolic Disease With the PGC-1alpha Gly482Ser Polymorphism. AB - Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1alpha) is a highly conserved transcriptional coactivator enriched in metabolically active tissues including liver, adipose, pancreas, and muscle. It plays a role in regulating whole body energy metabolism and its deregulation has been implicated in type 2 diabetes (T2D). A single nucleotide variant of the PPARGC1A gene (rs8192678) is associated with T2D susceptibility, relative risk of obesity and insulin resistance, and lower indices of beta cell function. This common polymorphism is within a highly conserved region of the bioactive protein and leads to a single amino acid substitution (glycine 482 to serine). Its prevalence and effects on metabolic parameters appear to vary depending on factors including ethnicity and sex, suggesting important interactions between genetics and cultural/environmental factors and associated disease risk. Interestingly, carriers of the serine allele respond better to some T2D interventions, illustrating the importance of understanding functional impacts of genetic variance on PGC-1alpha when targeting this pathway for personalized medicine. This review summarizes a growing body of literature surrounding possible links between the PGC-1alpha Gly482Ser single nucleotide polymorphism and diabetes, with focus on key clinical findings, affected metabolic systems, potential molecular mechanisms, and the influence of geographical or ethnic background on associated risk. PMID- 29186344 TI - MOCASSIN-prot: a multi-objective clustering approach for protein similarity networks. AB - Motivation: Proteins often include multiple conserved domains. Various evolutionary events including duplication and loss of domains, domain shuffling, as well as sequence divergence contribute to generating complexities in protein structures, and consequently, in their functions. The evolutionary history of proteins is hence best modeled through networks that incorporate information both from the sequence divergence and the domain content. Here, a game-theoretic approach proposed for protein network construction is adapted into the framework of multi-objective optimization, and extended to incorporate clustering refinement procedure. Results: The new method, MOCASSIN-prot, was applied to cluster multi-domain proteins from ten genomes. The performance of MOCASSIN-prot was compared against two protein clustering methods, Markov clustering (TRIBE MCL) and spectral clustering (SCPS). We showed that compared to these two methods, MOCASSIN-prot, which uses both domain composition and quantitative sequence similarity information, generates fewer false positives. It achieves more functionally coherent protein clusters and better differentiates protein families.

PMID- 29186343 TI - Relative contributions of neutral and non-neutral processes to clinal variation in calyx lobe length in the series Sakawanum (Asarum: Aristolochiaceae). AB - Background and Aims: Clines, the gradual variation in measurable traits along a geographical axis, play a major role in evolution and can contribute to our understanding of the relative roles of selective and neutral process in trait variation. Using genetic and morphological analyses, the relative contributions of neutral and non-neutral processes were explored to infer the evolutionary history of species of the series Sakawanum (genus Asarum), which shows significant clinal variation in calyx lobe length. Methods: A total of 27 populations covering the natural geographical distribution of the series Sakawanum were sampled. Six nuclear microsatellite markers were used to investigate genetic structure and genetic diversity. The lengths of calyx lobes of multiple populations were measured to quantify their geographical and taxonomic differentiation. To detect the potential impact of selective pressure, morphological differentiation was compared with genetic differentiation (QCT-FST comparison). Key Results: Average calyx lobe length of A. minamitanianum was 124.11 mm, while that of A. costatum was 13.80 mm. Though gradually changing along the geographical axis within series, calyx lobe lengths were significantly differentiated among the taxa. Genetic differentiation between taxa was low (FST = 0.099), but a significant geographical structure along the morphological cline was detected. Except for one taxon pair, pairwise QCT values were significantly higher than the neutral genetic measures of FST and G'ST. Conclusions: Divergent selection may have driven the calyx lobe length variation in series Sakawanum taxa, although the underlying mechanism is still not clear. The low genetic differentiation indicates recent divergence and/or gene flows between geographically close taxa. These neutral processes would also affect the clinal variation in calyx lobe lengths. Overall, this study implies the roles of population history and divergent selection in shaping the current cline of a flower trait in the series Sakawanum. PMID- 29186345 TI - Organizational Principles of Abstract Words in the Human Brain. AB - words constitute nearly half of the human lexicon and are critically associated with human abstract thoughts, yet little is known about how they are represented in the brain. We tested the neural basis of 2 classical cognitive notions of abstract meaning representation: by linguistic contexts and by semantic features. We collected fMRI BOLD responses for 360 abstract words and built theoretical representational models from state-of-the-art corpus-based natural language processing models and behavioral ratings of semantic features. Representational similarity analyses revealed that both linguistic contextual and semantic feature similarity affected the representation of abstract concepts, but in distinct neural levels. The corpus-based similarity was coded in the high-level linguistic processing system, whereas semantic feature information was reflected in distributed brain regions and in the principal component space derived from whole brain activation patterns. These findings highlight the multidimensional organization and the neural dissociation between linguistic contextual and featural aspects of abstract concepts. PMID- 29186346 TI - Pharmacokinetic Assessments of Liquiritin, Protocatechuic Aldehyde and Rosmarinic Acid in Rat Plasma by UPLC-MS-MS After Administration of ZibuPiyin Recipe. AB - The three analytes of the Traditional Chinese Medicine ZibuPiyin Recipe (ZBPYR), namely, liquiritin, protocatechuic aldehyde and rosmarinic acid, may synergistically play an important role in regulating memory and learning. However, the pharmacokinetic behaviors of these compounds after their co administration remain unclear. To this end, a selective and sensitive ultra performance liquid chromatography-tandem mass spectrometry method was developed and validated in rat plasma for the study of these three major bioactive ingredients in ZBPYR. The analytes in the plasma samples were separated on a Shiseido Capcell core C18 column using bendrofluazide as an internal standard, with a gradient mobile phase system of acetonitrile-water containing 0.1% formic acid. Electrospray ionization in the negative-ion mode and multiple reaction monitoring were used to identify and quantify the three analytes. All of the calibration curves showed good linearity (r > 0.992) over the concentration range, with a lower limit of quantification of 5 ng/mL. The precision of the analytical method was evaluated by intra- and inter-day assays, and the percentage of relative standard deviation (SD) was within 15%. Satisfactory extraction efficiency (between 83.4 and 99.4%) and matrix effects (76.4-107.4) were obtained by liquid-liquid extraction. The pharmacokinetic results showed that the three bioactive ingredients were rapidly absorbed and had a short terminal half-life in rats after oral administration of ZibuPiyin recipe. This UPLC-MS-MS study method used in this study may be useful for assessing the pharmacokinetic characteristics of various compounds, which would be helpful in determining their clinical potential. PMID- 29186347 TI - Severe Respiratory Illness Associated With Rhinovirus During the Enterovirus D68 Outbreak in the United States, August 2014-November 2014. AB - Background: In 2014, a nationwide outbreak of severe respiratory illness occurred in the United States, primarily associated with enterovirus D68 (EV-D68). A proportion of illness was associated with rhinoviruses (RVs) and other enteroviruses (EVs), which we aimed to characterize further. Methods: Respiratory specimens from pediatric and adult patients with respiratory illness were submitted to the Centers for Disease Control and Prevention during August 2014 November 2014. While initial laboratory testing focused on identification of EV D68, the negative specimens were typed by molecular sequencing to identify additional EV and RV types. Testing for other pathogens was not conducted. We compared available clinical and epidemiologic characteristics among patients with EV-D68 and RV species A-C identified. Results: Among 2629 typed specimens, 1012 were EV-D68 (39%) and 81 (3.1%) represented 24 other EV types; 968 were RVs (37%) covering 114 types and grouped into 3 human RV species (RV-A, 446; RV-B, 133; RV C, 389); and 568 (22%) had no RV or EV detected. EV-D68 was more frequently identified in patients who presented earlier in the investigation period. Among patients with EV-D68, RV-A, RV-B, or RV-C, the age distributions markedly differed. Clinical syndromes and intensive care unit admissions by age were largely similar. Conclusions: RVs were commonly associated with severe respiratory illness during a nationwide outbreak of EV-D68, and most clinical. Characteristics were similar between groups. A better understanding of the epidemiology of RVs and EVs is needed to help inform development and use of diagnostic tests, therapeutics, and preventive measures. PMID- 29186348 TI - Spiking Suppression Precedes Cued Attentional Enhancement of Neural Responses in Primary Visual Cortex. AB - Attending to a visual stimulus increases its detectability, even if gaze is directed elsewhere. This covert attentional selection is known to enhance spiking across many brain areas, including the primary visual cortex (V1). Here we investigate the temporal dynamics of attention-related spiking changes in V1 of macaques performing a task that separates attentional selection from the onset of visual stimulation. We found that preceding attentional enhancement there was a sharp, transient decline in spiking following presentation of an attention guiding cue. This disruption of V1 spiking was not observed in a task-naive subject that passively observed the same stimulus sequence, suggesting that sensory activation is insufficient to cause suppression. Following this suppression, attended stimuli evoked more spiking than unattended stimuli, matching previous reports of attention-related activity in V1. Laminar analyses revealed a distinct pattern of activation in feedback-associated layers during both the cue-induced suppression and subsequent attentional enhancement. These findings suggest that top-down modulation of V1 spiking can be bidirectional and result in either suppression or enhancement of spiking responses.

PMID- 29186350 TI - Macrophage enzyme and reduced inflammation drive brain correction of mucopolysaccharidosis IIIB by stem cell gene therapy. AB - Mucopolysaccharidosis IIIB is a paediatric lysosomal storage disease caused by deficiency of the enzyme alpha-N-acetylglucosaminidase (NAGLU), involved in the degradation of the glycosaminoglycan heparan sulphate. Absence of NAGLU leads to accumulation of partially degraded heparan sulphate within lysosomes and the extracellular matrix, giving rise to severe CNS degeneration with progressive cognitive impairment and behavioural problems. There are no therapies. Haematopoietic stem cell transplant shows great efficacy in the related disease mucopolysaccharidosis I, where donor-derived monocytes can transmigrate into the brain following bone marrow engraftment, secrete the missing enzyme and cross correct neighbouring cells. However, little neurological correction is achieved in patients with mucopolysaccharidosis IIIB. We have therefore developed an ex vivo haematopoietic stem cell gene therapy approach in a mouse model of mucopolysaccharidosis IIIB, using a high-titre lentiviral vector and the myeloid specific CD11b promoter, driving the expression of NAGLU (LV.NAGLU). To understand the mechanism of correction we also compared this with a poorly secreted version of NAGLU containing a C-terminal fusion to IGFII (LV.NAGLU IGFII). Mucopolysaccharidosis IIIB haematopoietic stem cells were transduced with vector, transplanted into myeloablated mucopolysaccharidosis IIIB mice and compared at 8 months of age with mice receiving a wild-type transplant. As the disease is characterized by increased inflammation, we also tested the anti inflammatory steroidal agent prednisolone alone, or in combination with LV.NAGLU, to understand the importance of inflammation on behaviour. NAGLU enzyme was substantially increased in the brain of LV.NAGLU and LV.NAGLU-IGFII-treated mice, with little expression in wild-type bone marrow transplanted mice. LV.NAGLU treatment led to behavioural correction, normalization of heparan sulphate and sulphation patterning, reduced inflammatory cytokine expression and correction of astrocytosis, microgliosis and lysosomal compartment size throughout the brain. The addition of prednisolone improved inflammatory aspects further. Substantial correction of lysosomal storage in neurons and astrocytes was also achieved in LV.NAGLU-IGFII-treated mice, despite limited enzyme secretion from engrafted macrophages in the brain. Interestingly both wild-type bone marrow transplant and prednisolone treatment alone corrected behaviour, despite having little effect on brain neuropathology. This was attributed to a decrease in peripheral inflammatory cytokines. Here we show significant neurological disease correction is achieved using haematopoietic stem cell gene therapy, suggesting this therapy alone or in combination with anti-inflammatories may improve neurological function in patients.

PMID- 29186352 TI - ATM Is Required for the Prolactin-Induced HSP90-Mediated Increase in Cellular Viability and Clonogenic Growth After DNA Damage. AB - Prolactin (PRL) acts as a survival factor for breast cancer cells, but the PRL signaling pathway and the mechanism are unknown. Previously, we identified the master chaperone, heat shock protein 90 (HSP90) alpha, as a prolactin-Janus kinase 2 (JAK2)-signal transducer and activator of transcription 5 (STAT5) target gene involved in survival, and here we investigated the role of HSP90 in the mechanism of PRL-induced viability in response to DNA damage. The ataxia telangiectasia mutated kinase (ATM) protein plays a critical role in the cellular response to double-strand DNA damage. We observed that PRL increased viability of breast cancer cells treated with doxorubicin or etoposide. The increase in cellular resistance is specific to the PRL receptor, because the PRL receptor antagonist, Delta1-9-G129R-hPRL, prevented the increase in viability. Two different HSP90 inhibitors, 17-allylamino-17-demethoxygeldanamycin and BIIB021, reduced the PRL-mediated increase in cell viability of doxorubicin-treated cells and led to a decrease in JAK2, ATM, and phosphorylated ATM protein levels. Inhibitors of JAK2 (G6) and ATM (KU55933) abolished the PRL-mediated increase in cell viability of DNA-damaged cells, supporting the involvement of each, as well as the crosstalk of ATM with the PRL pathway in the context of DNA damage. Drug synergism was detected between the ATM inhibitor (KU55933) and doxorubicin and between the HSP90 inhibitor (BIIB021) and doxorubicin. Short interfering RNA directed against ATM prevented the PRL-mediated increase in cell survival in two dimensional cell culture, three-dimensional collagen gel cultures, and clonogenic cell survival, after doxorubicin treatment. Our results indicate that ATM contributes to the PRL-JAK2-STAT5-HSP90 pathway in mediating cellular resistance to DNA-damaging agents.

PMID- 29186353 TI - Prevalence and clinical association of gene mutations through multiplex mutation testing in patients with NSCLC: results from the ETOP Lungscape Project. AB - Background: Reported prevalence of driver gene mutations in non-small-cell lung cancer (NSCLC) is highly variable and clinical correlations are emerging. Using NSCLC biomaterial and clinical data from the European Thoracic Oncology Platform Lungscape iBiobank, we explore the epidemiology of mutations and association to clinicopathologic features and patient outcome (relapse-free survival, time-to relapse, overall survival). Methods: Clinically annotated, resected stage I-III NSCLC FFPE tissue was assessed for gene mutation using a microfluidics-based multiplex PCR platform. Mutant-allele detection sensitivity is >1% for most of the ~150 (13 genes) mutations covered in the multiplex test. Results: Multiplex testing has been carried out in 2063 (76.2%) of the 2709 Lungscape cases (median follow-up 4.8 years). FFPE samples mostly date from 2005 to 2008, yet recently extracted DNA quality and quantity was generally good. Average DNA yield/case was 2.63 ug; 38 cases (1.4%) failed QC and were excluded from study; 95.1% of included cases allowed the complete panel of mutations to be tested. Most common were KRAS, MET, EGFR and PIK3CA mutations with overall prevalence of 23.0%, 6.8%, 5.4% and 4.9%, respectively. KRAS and EGFR mutations were significantly more frequent in adenocarcinomas: PIK3CA in squamous cell carcinomas. MET mutation prevalence did not differ between histology groups. EGFR mutations were found predominantly in never smokers; KRAS in current/former smokers. For all the above mutations, there was no difference in outcome between mutated and non-mutated cases. Conclusion: Archival FFPE NSCLC material is adequate for multiplex mutation analysis. In this large, predominantly European, clinically annotated stage I-III NSCLC cohort, none of the mutations characterized showed prognostic significance. PMID- 29186355 TI - Global proteomics profiling improves drug sensitivity prediction: results from a multi-omics, pan-cancer modeling approach. AB - Motivation: Proteomics profiling is increasingly being used for molecular stratification of cancer patients and cell-line panels. However, systematic assessment of the predictive power of large-scale proteomic technologies across various drug classes and cancer types is currently lacking. To that end, we carried out the first pan-cancer, multi-omics comparative analysis of the relative performance of two proteomic technologies, targeted reverse phase protein array (RPPA) and global mass spectrometry (MS), in terms of their accuracy for predicting the sensitivity of cancer cells to both cytotoxic chemotherapeutics and molecularly targeted anticancer compounds. Results: Our results in two cell-line panels demonstrate how MS profiling improves drug response predictions beyond that of the RPPA or the other omics profiles when used alone. However, frequent missing MS data values complicate its use in predictive modeling and required additional filtering, such as focusing on completely measured or known oncoproteins, to obtain maximal predictive performance. Rather strikingly, the two proteomics profiles provided complementary predictive signal both for the cytotoxic and targeted compounds. Further, information about the cellular-abundance of primary target proteins was found critical for predicting the response of targeted compounds, although the non-target features also contributed significantly to the predictive power. The clinical relevance of the selected protein markers was confirmed in cancer patient data. These results provide novel insights into the relative performance and optimal use of the widely applied proteomic technologies, MS and RPPA, which should prove useful in translational applications, such as defining the best combination of omics technologies and marker panels for understanding and predicting drug sensitivities in cancer patients.

PMID- 29186356 TI - Altered caudate connectivity is associated with executive dysfunction after traumatic brain injury. AB - Traumatic brain injury often produces executive dysfunction. This characteristic cognitive impairment often causes long-term problems with behaviour and personality. Frontal lobe injuries are associated with executive dysfunction, but it is unclear how these injuries relate to corticostriatal interactions that are known to play an important role in behavioural control. We hypothesized that executive dysfunction after traumatic brain injury would be associated with abnormal corticostriatal interactions, a question that has not previously been investigated. We used structural and functional MRI measures of connectivity to investigate this. Corticostriatal functional connectivity in healthy individuals was initially defined using a data-driven approach. A constrained independent component analysis approach was applied in 100 healthy adult dataset from the Human Connectome Project. Diffusion tractography was also performed to generate white matter tracts. The output of this analysis was used to compare corticostriatal functional connectivity and structural integrity between groups of 42 patients with traumatic brain injury and 21 age-matched controls. Subdivisions of the caudate and putamen had distinct patterns of functional connectivity. Traumatic brain injury patients showed disruption to functional connectivity between the caudate and a distributed set of cortical regions, including the anterior cingulate cortex. Cognitive impairments in the patients were mainly seen in processing speed and executive function, as well as increased levels of apathy and fatigue. Abnormalities of caudate functional connectivity correlated with these cognitive impairments, with reductions in right caudate connectivity associated with increased executive dysfunction, information processing speed and memory impairment. Structural connectivity, measured using diffusion tensor imaging between the caudate and anterior cingulate cortex was impaired and this also correlated with measures of executive dysfunction. We show for the first time that altered subcortical connectivity is associated with large scale network disruption in traumatic brain injury and that this disruption is related to the cognitive impairments seen in these patients. PMID- 29186357 TI - Outcome of ankle arthrodesis and ankle prosthesis: a review of the current status. AB - Introduction: In advanced stages of ankle osteoarthritis (OA), ankle arthrodesis (AA) or total ankle arthroplasty (TAR) may be necessary. Our purpose is to compare AA and total ankle replacement for the surgical management of end stage ankle OA. Sources of data: We conducted a literature search of PubMed, Medline, CINAHL, Cochrane, Embase and Google Scholar databases using the terms 'ankle' in combination with 'OA', 'arthrodesis', 'arthroplasty', 'joint fusion', 'joint replacement'. Studies where treatment was exclusively total ankle replacement or AA were excluded. Treatment characteristics and outcome parameters (overall postoperative outcome and complication rate) were reviewed. Areas of agreement: When counseling patients who are considering their options with regard to ankle arthritis treatment, surgeons should determine on an individual basis which procedure is more suitable. Areas of controversy: TAR has become an accepted treatment for end-stage OA, but revision rates for TAR are significant higher than for AA (odds ratio 2.28 95% confidence interval [CI], 1.63-3.19; P < 0.0001). Growing points: The results of TAA are gradually improving, but the procedure cannot yet be recommended for the routine management of ankle OA. Areas timely for developing research: Although there is some evidence to support TAR to conserve ankle motion and offer improved function and decreased pain with high satisfaction rates, revision rates for TAR are significantly higher than revision rates for AA. Proper patient selection should be better addressed in future studies for successful treatment of end-stage ankle OA. Level of evidence: Systematic review, level III.

AB - A comparative study of Diptera communities associated with pig carcasses was carried out in urban and natural settings in tropical mountain habitats of Southern Mexico. Schoenly-type traps were used to set out pig carcasses during 68 d of sampling effort. In total, 1,703 adult Diptera specimens were collected in both localities combined, and recording a total of 30 (morpho) species and 19 families. Compared to natural habitats, a significantly greater diversity in urban habitats, as well as a faster decomposition process of carcasses, was detected. Significant differences were also detected for the composition and structure of Dipteran communities between urban and natural sites. Dominant species of Calliphoridae for natural and urban habitats were represented by Compsomyiops spp. and Cochliomyia macellaria (Fabricius; Diptera: Calliphoridae), respectively. The properties of indicator species for urban and natural sites are discussed. Twenty Dipteran species were significantly associated to different decomposition stages. Such affinity would allow for estimating the post-mortem interval (PMI) in comparable situations. PMID- 29186359 TI - In the Piriform Cortex, the Primary Impetus for Information Encoding through Synaptic Plasticity Is Provided by Descending Rather than Ascending Olfactory Inputs. AB - Information encoding by means of persistent changes in synaptic strength supports long-term information storage and memory in structures such as the hippocampus. In the piriform cortex (PC), that engages in the processing of associative memory, only short-term synaptic plasticity has been described to date, both in vitro and in anesthetized rodents in vivo. Whether the PC maintains changes in synaptic strength for longer periods of time is unknown: Such a property would indicate that it can serve as a repository for long-term memories. Here, we report that in freely behaving animals, frequency-dependent synaptic plasticity does not occur in the anterior PC (aPC) following patterned stimulation of the olfactory bulb (OB). Naris closure changed action potential properties of aPC neurons and enabled expression of long-term potentiation (LTP) by OB stimulation, indicating that an intrinsic ability to express synaptic plasticity is present. Odor discrimination and categorization in the aPC is supported by descending inputs from the orbitofrontal cortex (OFC). Here, OFC stimulation resulted in LTP (>4 h), suggesting that this structure plays an important role in promoting information encoding through synaptic plasticity in the aPC. These persistent changes in synaptic strength are likely to comprise a means through which long term memories are encoded and/or retained in the PC. PMID- 29186360 TI - Longitudinal Functional Brain Mapping in Supernormals. AB - Prevention of age-related cognitive decline is an increasingly important topic. Recently, increased attention is being directed at understanding biological models of successful cognitive aging. Here, we examined resting-state brain regional low-frequency oscillations using functional magnetic resonance imaging in 19 older adults with excellent cognitive abilities (Supernormals), 28 older adults with normative cognition, 57 older adults with amnestic mild cognitive impairment, and 26 with Alzheimer's disease. We identified a "Supernormal map", a set of regions whose oscillations were resistant to the aging-associated neurodegenerative process, including the right fusiform gyrus, right middle frontal gyrus, right anterior cingulate cortex, left middle temporal gyrus, left precentral gyrus, and left orbitofrontal cortex. The map was unique to the Supernormals, differentiated this group from cognitive average-ager comparisons, and predicted a 1-year change in global cognition (indexed by the Montreal Cognitive Assessment scores, adjusted R2 = 0.68). The map was also correlated to Alzheimer's pathophysiological features (beta-amyloid/pTau ratio, adjusted R2 = 0.66) in participants with and without cognitive impairment. These findings in phenotypically successful cognitive agers suggest a divergent pattern of brain regions that may either reflect inherent neural integrity that contributes to Supernormals' cognitive success, or alternatively indicate adaptive reorganization to the demands of aging.

AB - Squamous cell carcinoma (SCC) of the skin is a keratinocyte malignancy characterized by tumors presenting on sun-exposed areas with surgery being the mainstay treatment. Despite advances in targeted therapy in other skin cancers, such as basal cell carcinoma and melanoma, there have been no such advances in the treatment of SCC. This is partly due to an incomplete knowledge of the pathogenesis of SCC. We have recently identified a protein kinase C-associated kinase (PKK) as a potential tumor suppressor in SCC. We now describe a novel conditional PKK knockout mouse model, which demonstrates that PKK deficiency promotes SCC formation during chemically induced tumorigenesis. Our results further support that PKK functions as a tumor suppressor in skin keratinocytes and is important in the pathogenesis of SCC of the skin. We further define the interactions of keratinocyte PKK with TP63 and NF-kappaB signaling, highlighting the importance of this protein as a tumor suppressor in SCC development. PMID- 29186363 TI - Transformation of Visual Representations Across Ventral Stream Body-selective Patches. AB - Although the neural processing of visual images of bodies is critical for survival, it is much less well understood than face processing. Functional imaging studies demonstrated body selective regions in primate inferior temporal cortex. To advance our understanding of how the visual brain represents bodies, we compared the representation of animate and inanimate objects in two such body patches with fMRI-guided single unit recordings in rhesus monkeys. We found that the middle Superior Temporal Sulcus body patch (MSB) distinguishes to a greater extent bodies from non-bodies than the anterior Superior Temporal Sulcus body patch (ASB). Importantly, ASB carried more viewpoint-tolerant information about body posture and body identity than MSB, while MSB showed greater orientation selectivity. Combined with previous work on faces, this suggests that an increase in view-tolerant representations, coupled with a refined individuation, along the visual hierarchy is a general property of information processing within the inferior temporal cortex. PMID- 29186364 TI - Efficacy and Safety of Oseltamivir in Children: Systematic Review and Individual Patient Data Meta-analysis of Randomized Controlled Trials. AB - Background: Oseltamivir has been used to treat children with influenza for nearly 2 decades, with treatment currently approved for infants aged >=2 weeks. However, efficacy and safety remain controversial. Newer randomized, placebo-controlled trials (RCTs), not included in previous meta-analyses, can add to the evidence base. Methods: We conducted a systematic review to identify RCTs of oseltamivir therapy in children. We obtained individual patient data and examined protocol defined outcomes. We then conducted a 2-stage, random-effects meta-analysis to determine the efficacy of treatment in reducing the duration of illness, estimated using differences in restricted mean survival time (RMST) by treatment group. We also examined complications and safety. Results: We identified 5 trials that included 2561 patients in the intention-to-treat (ITT) and 1598 in the intention-to-treat infected (ITTI) populations. Overall, oseltamivir treatment significantly reduced the duration of illness in the ITTI population (RMST difference, -17.6 hours; 95% confidence interval [CI], -34.7 to -0.62 hours). In trials that enrolled patients without asthma, the difference was larger (-29.9 hours; 95% CI, -53.9 to -5.8 hours). Risk of otitis media was 34% lower in the ITTI population. Vomiting was the only adverse event with a significantly higher risk in the treatment group. Conclusions: Despite substantial heterogeneity in pediatric trials, we found that treatment with oseltamivir significantly reduced the duration of illness in those with influenza and lowered the risk of developing otitis media. Alternative endpoints may be required to evaluate the efficacy of oseltamivir in pediatric patients with asthma. PMID- 29186366 TI - Human endometrial stromal cell decidualization requires transcriptional reprogramming by PLZF. AB - Infertility and early embryo miscarriage is linked to inadequate endometrial decidualization. Although transcriptional reprogramming is known to drive decidualization in response to progesterone, the key signaling effectors that directly mediate this hormone response are not fully known. This knowledge gap is clinically significant because identifying the early signals that directly mediate progesterone-driven decidualization will address some of the current limitations in diagnosing and therapeutically treating patients at most risk for early pregnancy loss. We recently revealed that the promyelocytic leukemia zinc finger (PLZF) is a direct target of the progesterone receptor and is essential for decidualization of human endometrial stromal cells (hESCs). The purpose of this current work was to identify the genome-wide transcriptional program that is controlled by PLZF during hESC decidualization using an established in vitro hESC culture model, siRNA-mediated knockdown methods, and RNA-sequencing technology followed by bioinformatic analysis and validation. We discovered that PLZF is critical in the regulation of genes that are involved in cellular processes that are essential for the archetypal morphological and functional changes that occur when hESCs transform into epithelioid decidual cells such as proliferation and cell motility. We predict that the transcriptome datasets identified in this study will not only contribute to a broader understanding of PLZF-dependent endometrial decidualization at the molecular level but may advance the development of more effective molecular diagnostics and therapeutics for the clinical management of female infertility and subfertility that is based on a dysfunctional endometrium. PMID- 29186367 TI - Vascular peroxidase 1 mediates hypoxia-induced pulmonary artery smooth muscle cell proliferation, apoptosis resistance and migration. AB - Aims: Reactive oxygen species (ROS) play essential roles in the pulmonary vascular remodelling associated with hypoxia-induced pulmonary hypertension (PH). Vascular peroxidase 1 (VPO1) is a newly identified haeme-containing peroxidase that accelerates oxidative stress development in the vasculature. This study aimed to determine the potential role of VPO1 in hypoxia-induced PH-related vascular remodelling. Methods and results: The vascular morphology and VPO1 expression were assessed in the pulmonary arteries of Sprague-Dawley (SD) rats. Nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 4 (NOX4) and VPO1 expression and HOCl production were significantly increased in hypoxic rats, which also exhibited obvious vascular remodelling. Furthermore, a hypoxia-induced PH model was generated by exposing primary rat pulmonary artery smooth muscle cells (PASMCs) to hypoxic conditions (3% O2, 48 h), which significantly increased the expression of NOX4 and VPO1 and the production of HOCl. These hypoxic changes were accompanied by enhanced proliferation, apoptosis resistance, and migration. In PASMCs, hypoxia-induced changes, including effects on the expression of cell cycle regulators (cyclin B1 and cyclin D1), apoptosis-related proteins (bax, bcl 2, and cleaved caspase-3), migration promoters (matrix metalloproteinases 2 and 9), and NF-kappaB expression, as well as the production of HOCl, were all inhibited by silencing VPO1 with small interfering RNAs. Moreover, treatment with HOCl under hypoxic conditions upregulated NF-kappaB expression and enhanced proliferation, apoptosis resistance, and migration in PASMCs, whereas BAY 11-7082 (an inhibitor of NF-kappaB) significantly inhibited these effects. Conclusion: Collectively, these results demonstrate that VPO1 promotes hypoxia-induced proliferation, apoptosis resistance, and migration in PASMCs via the NOX4/VPO1/HOCl/NF-kappaB signalling pathway.

AB - Hypomyelinating leukodystrophies are a heterogeneous group of disorders with a clinical presentation that often includes early-onset nystagmus, ataxia and spasticity and a wide range of severity. Using next-generation sequencing techniques and GeneMatcher, we identified four unrelated patients with brain hypomyelination, all with the same recurrent dominant mutation, c.754G>A p.(Asp252Asn), in TMEM106B. The mutation was confirmed as de novo in three of the cases, and the mildly affected father of the fourth affected individual was confirmed as mosaic for this variant. The protein encoded by TMEM106B is poorly characterized but is reported to have a role in regulation of lysosomal trafficking. Polymorphisms in TMEM106B are thought to modify disease onset in frontotemporal dementia, but its relation to myelination is not understood. Clinical presentation in three of the four patients is remarkably benign compared to other hypomyelinating disorders, with congenital nystagmus and mild motor delay. These findings add TMEM106B to the growing list of genes causing hypomyelinating disorders and emphasize the essential role lysosomes play in myelination. PMID- 29186365 TI - High Treatment Uptake in Human Immunodeficiency Virus/Hepatitis C Virus Coinfected Patients After Unrestricted Access to Direct-Acting Antivirals in the Netherlands. AB - Background: The Netherlands has provided unrestricted access to direct-acting antivirals (DAAs) since November 2015. We analyzed the nationwide hepatitis C virus (HCV) treatment uptake among patients coinfected with human immunodeficiency virus (HIV) and HCV. Methods: Data were obtained from the ATHENA HIV observational cohort in which >98% of HIV-infected patients ever registered since 1998 are included. Patients were included if they ever had 1 positive HCV RNA result, did not have spontaneous clearance, and were known to still be in care. Treatment uptake and outcome were assessed. When patients were treated more than once, data were included from only the most recent treatment episode. Data were updated until February 2017. In addition, each treatment center was queried in April 2017 for a data update on DAA treatment and achieved sustained virological response. Results: Of 23574 HIV-infected patients ever linked to care, 1471 HCV-coinfected patients (69% men who have sex with men, 15% persons who [formerly] injected drugs, and 15% with another HIV transmission route) fulfilled the inclusion criteria. Of these, 87% (1284 of 1471) had ever initiated HCV treatment between 2000 and 2017, 76% (1124 of 1471) had their HCV infection cured; DAA treatment results were pending in 6% (92 of 1471). Among men who have sex with men, 83% (844 of 1022) had their HCV infection cured, and DAA treatment results were pending in 6% (66 of 1022). Overall, 187 patients had never initiated treatment, DAAs had failed in 14, and a pegylated interferon-alfa-based regimen had failed in 54. Conclusions: Fifteen months after unrestricted DAA availability the majority of HIV/HCV-coinfected patients in the Netherlands have their HCV infection cured (76%) or are awaiting DAA treatment results (6%). This rapid treatment scale-up may contribute to future HCV elimination among these patients. PMID- 29186372 TI - Irritable Bowel-like Symptoms in Ulcerative Colitis are as Common in Patients in Deep Remission as in Inflammation: Results From a Population-based Study [the IBSEN Study]. AB - Background and Aims: An increased prevalence of irritable bowel syndrome [IBS] like symptoms has been reported in patients with ulcerative colitis [UC]. Whether ongoing inflammation increases the prevalence of such symptoms is unknown. The aims of this study were to determine the prevalence of IBS-like symptoms in a population-based cohort of UC patients 20 years after diagnosis, and to assess the possible association between such symptoms and ongoing inflammation. Methods: Patients diagnosed with UC between 1990 and 1994, in a geographically well defined area, were included in a prospective follow-up study, and IBS symptoms according to Rome III criteria were recorded 20 years after diagnosis. The patients underwent colonoscopy with biopsies and/or the level of faecal calprotectin was analysed. Results: A total of 260 patients answered the Rome III questionnaire. The overall prevalence of IBS-like symptoms was 27%. In patients who had no signs of inflammation in colonic biopsies [n = 96] [deep remission], the prevalence was 29%. No difference in prevalence of IBS-like symptoms was found between patients with ongoing inflammation and patients in deep remission. Conclusions: IBS-like symptoms in UC patients are frequent after 20 years of disease. Deep remission did not change the frequency of IBS-like symptoms. PMID- 29186370 TI - Comparative Genomics of Pathogenic and Nonpathogenic Beetle-Vectored Fungi in the Genus Geosmithia. AB - Geosmithia morbida is an emerging fungal pathogen which serves as a model for examining the evolutionary processes behind pathogenicity because it is one of two known pathogens within a genus of mostly saprophytic, beetle-associated, fungi. This pathogen causes thousand cankers disease in black walnut trees and is vectored into the host via the walnut twig beetle. Geosmithia morbida was first detected in western United States and currently threatens the timber industry concentrated in eastern United States. We sequenced the genomes of G. morbida in a previous study and two nonpathogenic Geosmithia species in this work and compared these species to other fungal pathogens and nonpathogens to identify genes under positive selection in G. morbida that may be associated with pathogenicity. Geosmithia morbida possesses one of the smallest genomes among the fungal species observed in this study, and one of the smallest fungal pathogen genomes to date. The enzymatic profile in this pathogen is very similar to its nonpathogenic relatives. Our findings indicate that genome reduction or retention of a smaller genome may be an important adaptative force during the evolution of a specialized lifestyle in fungal species that occupy a specificniche, such as beetle vectored tree pathogens. We also present potential genes under selection in G. morbida that could be important for adaptation to a pathogenic lifestyle. PMID- 29186374 TI - Interview with Professor Valter Longo. PMID- 29186373 TI - CCR2 expression on circulating monocytes is associated with arterial wall inflammation assessed by 18F-FDG PET/CT in patients at risk for cardiovascular disease. AB - Aims: Circulating monocytes infiltrate the plaque and differentiate into macrophages, contributing to an inflammatory environment which is associated with higher risk of cardiovascular events. Although the pivotal role of circulating monocytes in plaque inflammation has been firmly established, the search continues to identify specific monocyte subsets that may be especially atherogenic. Therefore, we evaluated the relation between monocyte phenotype, particularly surface receptor expression, and arterial wall inflammation in patients at increased cardiovascular risk. Methods and results: We performed a multivariate linear regression analysis in 79 patients at increased cardiovascular risk who had both an 18F-fluorodeoxyglucose positron emission tomography/computed tomography to assess arterial wall inflammation and extensive monocyte characterization (using flow cytometry). We found that CCR2, a monocyte chemokine receptor essential for transmigration, significantly correlates with arterial wall inflammation. This relationship was independent of traditional cardiovascular risk factors and statin use (beta = 0.429, P = 0.015). We found no relation between arterial wall inflammation and monocyte count or monocyte subsets, namely CD14+CD16-, CD14+CD16+, CD14+CD16 ++, CCR5+, CD18+, CD11b+, or CD11c+ monocytes. Conclusion: Monocyte CCR2 expression is associated with arterial wall inflammation in patients at increased cardiovascular risk. Our data warrant further studies to assess if inhibition of CCR2 may attenuate atherosclerotic plaque inflammation. PMID- 29186375 TI - Unilateral pulmonary oedema after minimally invasive mitral valve surgery: a single-centre experience. AB - OBJECTIVES: Unilateral pulmonary oedema (UPE) is a rare but potentially life threatening complication that has been described after minimally invasive mitral valve surgery (MICS). Over the last 8 years, we have witnessed, in our institution, several cases of severe UPE requiring immediate postoperative extracorporeal life support after MICS. Reviewing the available literature, data regarding this complication after MICS are rare. Consequently, we decided to retrospectively analyse patients scheduled for MICS in our institution. METHODS: After approval by our institutional review board, 256 MICS patients were analysed. As a primary end-point, we defined a newly developed UPE, radiographically evident within the first 24 h postoperatively. Secondary end points were length of stay in the intensive care unit, length of stay in the hospital and in-hospital mortality. Chest radiographs were analysed by an independent consultant of radiology. RESULTS: Fifty-one (19.9%) patients showed increased right-sided pulmonary vascular congestion in the 1st postoperative chest radiography performed in the intensive care unit. Five (1.95%) patients immediately required extracorporeal life support after admission to the intensive care unit. Cardiopulmonary bypass time was significantly longer in the UPE group [UPE vs non-UPE 213 (49) vs 196 (43) min; P = 0.013]. More patients with UPE showed a preoperative increase of C-reactive protein >0.4265 mg/dl (P = 0.05). Logistic regression analysis identified a preoperative increase in C-reactive protein >0.4265 mg/dl as well as a prolonged cardiopulmonary bypass time (odds ratio 1.009, 95% confidence level 1.002-1.016; P = 0.014) independent risk factors, significantly associated with the development of UPE (odds ratio 2.583, 95% confidence interval 1.275-5.233; P = 0.008), a prolonged cardiopulmonary bypass time (odds ratio 1.009, 95% confidence interval 1.002-1.016; P = 0.014). The presence of pulmonary hypertension (odds ratio 0.273, 95% confidence interval 0.08-0.84; P = 0.02) seemed to be a protective factor regarding the genesis of UPE. CONCLUSIONS: In accordance with the rarely available literature regarding UPE after MICS, our analysis led us to hypothesize the possibility of an inflammatory disposition for UPE. The role of pulmonary hypertension remains unclear in our patient population. Clinical Trials Number: NCT02655094. PMID- 29186376 TI - Evaluation of Semiochemical-Baited Traps for Monitoring the Pea Leaf Weevil, Sitona lineatus (Coleoptera: Curculionidae) in Field Pea Crops. AB - The pea leaf weevil (PLW), Sitona lineatus L., is a pest of field pea (Pisum sativum L.) and faba bean (Vicia faba L.) that recently invaded the Canadian Prairie Provinces. Although most damage is done by larvae that feed on root nodules, adults are easier to monitor than larvae. Both male and female weevils respond to a male-produced aggregation pheromone and to volatiles released by host plants. The current study tests the attractiveness of synthetic aggregation pheromone, 4-methyl-3,5-heptanedione, and host plant volatiles linalool, (Z)-3 hexenol, and (Z)-3-hexenyl acetate to PLWs in spring when weevils are reproductively active and in fall when weevils seek overwintering sites. Different combinations of semiochemical lures at various doses, released from a variety of devices were tested in pitfall traps. Semiochemical-baited traps captured both male and female weevils in both seasons but the sex ratio varied with season. Weevils did not respond in a dose-dependent manner to pheromone, as all pheromone lures were equally attractive. Pheromone release rate was determined by the release device and not the pheromone dose in the lure. The addition of plant volatiles sometimes increased weevil captures but plant volatiles alone were not attractive to PLW adults. An additional study tested the effect of trap type on weevil capture. Of the 12 different trap types tested, pheromone-baited pitfall traps were most successful in attracting and retaining weevils. Bycatch of other Sitona species was limited to a few specimens of the sweet clover weevil, Sitona cylindricollis Fahraeus.

AB - Summary: Analysis pipelines are an essential part of bioinformatics research, and ad hoc pipelines are frequently created by researchers for prototyping and proof of-concept purposes. However, most existing pipeline management system or workflow engines are too complex for rapid prototyping or learning the pipeline concept. A lightweight, user-friendly and flexible solution is thus desirable. In this study, we developed a new pipeline construction and maintenance tool, PipelineDog. This is a web-based integrated development environment with a modern web graphical user interface. It offers cross-platform compatibility, project management capabilities, code formatting and error checking functions and an online repository. It uses an easy-to-read/write script system that encourages code reuse. With the online repository, it also encourages sharing of pipelines, which enhances analysis reproducibility and accountability. For most users, PipelineDog requires no software installation. Overall, this web application provides a way to rapidly create and easily manage pipelines. Availability and implementation: PipelineDog web app is freely available at http://web.pipeline.dog.

PMID- 29186377 TI - Oxytocin-Oxytocin Receptor Systems Facilitate Social Defeat Posture in Male Mice. AB - Social stress has deteriorating effects on various psychiatric diseases. In animal models, exposure to socially dominant conspecifics (i.e., social defeat stress) evokes a species-specific defeat posture via unknown mechanisms. Oxytocin neurons have been shown to be activated by stressful stimuli and to have prosocial and anxiolytic actions. The roles of oxytocin during social defeat stress remain unclear. Expression of c-Fos, a marker of neuronal activation, in oxytocin neurons and in oxytocin receptor-expressing neurons was investigated in mice. The projection of oxytocin neurons was examined with an anterograde viral tracer, which induces selective expression of membrane-targeted palmitoylated green fluorescent protein in oxytocin neurons. Defensive behaviors during double exposure to social defeat stress in oxytocin receptor-deficient mice were analyzed. After social defeat stress, expression of c-Fos protein was increased in oxytocin neurons of the bed nucleus of the stria terminalis, supraoptic nucleus, and paraventricular hypothalamic nucleus. Expression of c-Fos protein was also increased in oxytocin receptor-expressing neurons of brain regions, including the ventrolateral part of the ventromedial hypothalamus and ventrolateral periaqueductal gray. Projecting fibers from paraventricular hypothalamic oxytocin neurons were found in the ventrolateral part of the ventromedial hypothalamus and in the ventrolateral periaqueductal gray. Oxytocin receptor-deficient mice showed reduced defeat posture during the second social defeat stress. These findings suggest that social defeat stress activates oxytocin-oxytocin receptor systems, and the findings are consistent with the view that activation of the oxytocin receptor in brain regions, including the ventrolateral part of the ventromedial hypothalamus and the ventrolateral periaqueductal gray, facilitates social defeat posture. PMID- 29186379 TI - Development of a high-density linkage map and chromosome segment substitution lines for Japanese soybean cultivar Enrei. AB - Using progeny of a cross between Japanese soybean Enrei and Chinese soybean Peking, we developed a high-density linkage map and chromosomal segment substitution lines (CSSLs). The map consists of 2,177 markers with polymorphism information for 32 accessions and provides a detailed genetic framework for these markers. The marker order on the linkage map revealed close agreement with that on the chromosome-scale assembly, Wm82.a2.v1. The differences, especially on Chr. 5 and Chr. 11, in the present map provides information to identify regions in the genome assembly where additional information is required to resolve marker order and assign remaining scaffolds. To cover the entire soybean genome, we used 999 BC3F2 backcross plants and selected 103 CSSLs carrying chromosomal segments from Peking in the genetic background of Enrei. Using these low-genetic-complexity resources, we dissected variation in traits related to flowering, maturity and yield into approximately 50 reproducible quantitative trait loci (QTLs) and evaluated QTLs with small genetic effects as single genetic factors in a uniform genetic background. CSSLs developed in this study may be good starting material for removing the unfavourable characteristics of Peking during pre-breeding and for isolation of genes conferring disease and stress resistance that have not yet been characterized. PMID- 29186380 TI - Impact of T-cell-mediated immune response on xenogeneic heart valve transplantation: short-term success and mid-term failure. AB - OBJECTIVES: Allogeneic frozen cryopreserved heart valves (allografts or homografts) are commonly used in clinical practice. A major obstacle for their application is the limited availability in particular for paediatrics. Allogeneic large animal studies revealed that alternative ice-free cryopreservation (IFC) results in better matrix preservation and reduced immunogenicity. The objective of this study was to evaluate xenogeneic (porcine) compared with allogeneic (ovine) IFC heart valves in a large animal study. METHODS: IFC xenografts and allografts were transplanted in 12 juvenile merino sheep for 1-12 weeks. Immunohistochemistry, ex vivo computed tomography scans and transforming growth factor-beta release profiles were analysed to evaluate postimplantation immunopathology. In addition, near-infrared multiphoton imaging and Raman spectroscopy were employed to evaluate matrix integrity of the leaflets. RESULTS: Acellular leaflets were observed in both groups 1 week after implantation. Allogeneic leaflets remained acellular throughout the entire study. In contrast, xenogeneic valves were infiltrated with abundant T-cells and severely thickened over time. No collagen or elastin changes could be detected in either group using multiphoton imaging. Raman spectroscopy with principal component analysis focusing on matrix-specific peaks confirmed no significant differences for explanted allografts. However, xenografts demonstrated clear matrix changes, enabling detection of distinct inflammatory-driven changes but without variations in the level of transforming growth factor-beta. CONCLUSIONS: Despite short-term success, mid-term failure of xenogeneic IFC grafts due to a T-cell-mediated extracellular matrix-triggered immune response was shown.

PMID- 29186382 TI - A modified technique for orthotopic heart transplantation to minimize warm ischaemic time. AB - Prolonged allograft ischaemic time in heart transplantation adversely impacts the performance of the donor heart in the immediate postoperative period and ultimately results in decreased post-transplant survival. Therefore, optimal surgical technique for heart transplantation should aim to minimize allograft ischaemic time. Here, we report a case of successful orthotopic heart transplantation using a modified technique to reduce allograft ischaemic time and warm ischaemic time. PMID- 29186383 TI - Effects of Low Temperature on Spider Mite Control by Intermittent Ultraviolet-B Irradiation for Practical Use in Greenhouse Strawberries. AB - The application of ultraviolet-B (UVB) radiation to control spider mites is challenging as a key technology for integrated pest management (IPM) in greenhouse strawberries in Japan. To address this, concurrent use of phytoseiid mites and reduced UVB irradiance is desirable to ensure control effects in areas shaded from UVB radiation and to minimize the sunscald in winter, respectively. We designed experiments reproducing the UVB dose on the lower leaf surfaces in strawberry and evaluated the effects of intermittent UVB irradiation at midnight for practical application in the greenhouse and low temperature on the survival of the spider mite Tetranychus urticae Koch (Acari: Tetranychidae) and damage to the phytoseiid mite Neoseiulus californicus (McGregor) (Acari: Phytoseiidae). The midnight intermittent UVB irradiation effectively suppressed egg hatching and development of larvae of T. urticae, and the control effect was reinforced at 20 degrees C (no eggs hatched at 0.13 kJ m-2 d-1) rather than, at 25 degrees C (70.8% eggs hatched). In contrast, the hatchability of N. californicus eggs was unaffected by intermittent UVB irradiation at 0.27 kJ m-2 d-1 at 25 degrees C and 20 degrees C. However, residual effects of UVB irradiation to N. californicus eggs on survival of hatched larvae were seen, so that reducing the UVB dose is also advantageous for this phytoseiid mite. N. californicus showed a photoreactivation capacity, whereas their UVB tolerance was improved by prey species, suggesting the possibility of the improvement of phytoseiid mites by diet. The reduction of UVB dose and concurrent use of phytoseiid mites increase reliability of the UVB method in IPM strategies in strawberry greenhouse. PMID- 29186384 TI - PlanNET: homology-based predicted interactome for multiple planarian transcriptomes. AB - Motivation: Planarians are emerging as a model organism to study regeneration in animals. However, the little available data of protein-protein interactions hinders the advances in understanding the mechanisms underlying its regenerating capabilities. Results: We have developed a protocol to predict protein-protein interactions using sequence homology data and a reference Human interactome. This methodology was applied on 11 Schmidtea mediterranea transcriptomic sequence datasets. Then, using Neo4j as our database manager, we developed PlanNET, a web application to explore the multiplicity of networks and the associated sequence annotations. By mapping RNA-seq expression experiments onto the predicted networks, and allowing a transcript-centric exploration of the planarian interactome, we provide researchers with a useful tool to analyse possible pathways and to design new experiments, as well as a reproducible methodology to predict, store, and explore protein interaction networks for non-model organisms.

AB - Motivation: The traditional view of cancer evolution states that a cancer genome accumulates a sequential ordering of mutations over a long period of time. However, in recent years it has been suggested that a cancer genome may instead undergo a one-time catastrophic event, such as chromothripsis, where a large number of mutations instead occur simultaneously. A number of potential signatures of chromothripsis have been proposed. In this work we provide a rigorous formulation and analysis of the "ability to walk the derivative chromosome" signature originally proposed by Korbel and Campbell (2013). In particular, we show that this signature, as originally envisioned, may not always be present in a chromothripsis genome and we provide a precise quantification of under what circumstances it would be present. We also propose a variation on this signature, the H/T alternating fraction, which allows us to overcome some of the limitations of the original signature. Results: We apply our measure to both simulated data and a previously analyzed real cancer dataset and find that the H/T alternating fraction may provide useful signal for distinguishing genomes having acquired mutations simultaneously from those acquired in a sequential fashion. Availability: An implementation of the H/T alternating fraction is available at https://bitbucket.org/oesperlab/ht-altfrac. Contact: loesper@carleton.edu.

PMID- 29186386 TI - Gene Expression Pattern in Response to Cholecalciferol Supplementation Highlights Cubilin as a Major Protein of 25(OH)D Uptake in Adipocytes and Male Mice White Adipose Tissue. AB - It is well established that the active form of vitamin D (i.e., 1,25 dihydroxyvitamin D [1,25(OH)2D]) regulates the expression of genes involved in its own metabolism and transport in the kidney and possibly in the liver. However, little is known about the transcriptional impact of cholecalciferol supplementation on white adipose tissue (WAT) and adipocytes, which are a major site of vitamin D and 25-hydroxyvitamin D [25(OH)D] storage in the organism. To fill this gap, we investigated the impact of cholecalciferol supplementation in WAT via a panel of genes coding for enzymes and proteins involved in vitamin D metabolism and uptake. Mice supplemented with cholecalciferol (15,000 IU/kg of body weight per day) for 4 days showed decreased messenger RNA (mRNA) levels of proteins involved in cholecalciferol metabolism (Cyp24a1, Cyp27a1) and decreased cubilin mRNA levels in WAT. These data were partly confirmed in 3T3-L1 adipocytes incubated with 1,25(OH)2D. The downregulation of cubilin mRNA observed in WAT and in 3T3-L1 was confirmed at the protein level in WAT and at the mRNA level in human primary adipocytes. Vitamin D receptor (VDR) agonist (EB1089) and RNA interference approaches demonstrated that VDR was involved in this regulation. Furthermore, chemical inhibitor and RNA inference analysis demonstrated that cubilin was involved in 25(OH)D uptake by adipocytes. This study established an overall snapshot of the genes regulated by cholecalciferol in mouse WAT and cell autonomously in adipocytes. We highlighted that the regulation of cubilin expression was mediated by a VDR-dependent mechanism, and we demonstrated that cubilin was involved in 25(OH)D uptake by adipocytes. PMID- 29186387 TI - Resveratrol Intake During Pregnancy and Lactation Modulates the Early Metabolic Effects of Maternal Nutrition Differently in Male and Female Offspring. AB - Poor maternal nutrition can have detrimental long-term consequences on energy homeostasis in the offspring. Resveratrol exerts antioxidant and antiobesity actions, but its impact during development remains largely unknown. We hypothesized that resveratrol intake during pregnancy and lactation could improve the effects of poor maternal nutrition on offspring metabolism. Wistar rats received a low-fat diet (LFD; 10.2% kcal from fat) or high-fat diet (HFD; 61.6% kcal from fat), with half of each group receiving resveratrol in their drinking water (50 mg/L) during pregnancy and lactation. Body weight (BW) of dams was measured at treatment onset and weaning [postnatal day (PND) 21] and of pups at birth and PND21, at which time dams and pups were euthanized. Although HFD dams consumed more energy, their BW at the end of lactation was unaffected. Mean litter size was not modified by maternal diet or resveratrol. At birth, male offspring from HFD and resveratrol (HFD + R) dams weighed less than those from LFD and resveratrol (LFD + R) dams. On PND21, pups of both sexes from HFD dams weighed more, had more visceral adipose tissue (VAT) and subcutaneous adipose tissue (SCAT), and had higher serum leptin levels than those from LFD dams. Resveratrol reduced BW, leptin, VAT, and SCAT, with females being more affected, but increased glycemia. Neuropeptide levels were unaffected by resveratrol. In conclusion, resveratrol intake during pregnancy and lactation decreased BW and adipose tissue content in offspring of dams on an HFD but did not affect offspring from LFD-fed dams, suggesting that the potential protective effects of resveratrol during gestation/lactation are diet dependent. PMID- 29186389 TI - The effect of colchicine administration on postoperative pleural effusion following lung resection: a randomized blinded placebo-controlled feasibility pilot study. AB - OBJECTIVES: This substudy of the colchicine for prevention of perioperative atrial fibrillation (COP-AF) pilot trial seeks to assess the effect of colchicine administration on the volume of postoperative pleural drainage, duration of chest tube in situ and length of stay following lung resection. METHODS: Between April 2014 and April 2015, 100 patients undergoing lung resection at 2 tertiary care centres participated in a pilot blinded randomized trial comparing perioperative twice daily 0.6 mg of colchicine orally (n = 49) or placebo (n = 51) twice daily for 10 days. The primary outcome was total pleural drainage volume, which was recorded in 8-h intervals for the first 2 postoperative days per standardized protocol. RESULTS: Only 1 patient did not complete the trial. The mean volume of pleural drainage at 40-h mark postoperation was significantly less in the colchicine group (550.9 ml) compared with the placebo group (741.3 ml, P = 0.039). Compared with the placebo group, the colchicine group showed significantly less mean pleural drainage on postoperative Day 2 (583.8 vs 763.3 ml, P = 0.039) and beyond. There were no differences in mean time to chest tube removal (6.8 days for the colchicine group vs 5.9 days for the placebo group, P = 0.585) and mean hospital length of stay (7.4 vs 6.9 days, P = 0.641). CONCLUSIONS: Oral colchicine is potentially effective in diminishing the amount of pleural drainage following lung resection and can be considered in patients at high risk of large postoperative pleural effusion. A full-scale, prospective placebo-controlled randomized trial is needed to assess the clinical significance of perioperative colchicine administration following oncological lung resection. PMID- 29186388 TI - Walking, Gross Motor Development, and Brain Functional Connectivity in Infants and Toddlers. AB - Infant gross motor development is vital to adaptive function and predictive of both cognitive outcomes and neurodevelopmental disorders. However, little is known about neural systems underlying the emergence of walking and general gross motor abilities. Using resting state fcMRI, we identified functional brain networks associated with walking and gross motor scores in a mixed cross sectional and longitudinal cohort of infants at high and low risk for autism spectrum disorder, who represent a dimensionally distributed range of motor function. At age 12 months, functional connectivity of motor and default mode networks was correlated with walking, whereas dorsal attention and posterior cingulo-opercular networks were implicated at age 24 months. Analyses of general gross motor function also revealed involvement of motor and default mode networks at 12 and 24 months, with dorsal attention, cingulo-opercular, frontoparietal, and subcortical networks additionally implicated at 24 months. These findings suggest that changes in network-level brain-behavior relationships underlie the emergence and consolidation of walking and gross motor abilities in the toddler period. This initial description of network substrates of early gross motor development may inform hypotheses regarding neural systems contributing to typical and atypical motor outcomes, as well as neurodevelopmental disorders associated with motor dysfunction. PMID- 29186391 TI - Longitudinal Trends in the Prevalence of Detectable HIV Viremia: Population-Based Evidence From Rural KwaZulu-Natal, South Africa. AB - Background: The prevalence of detectable viremia has previously been used to infer the potential for ongoing human immunodeficiency virus (HIV) transmission. To date, no study has evaluated the longitudinal change in the prevalence of detectable viremia within the HIV-positive community (PDV+) and the entire population (PDVP) using data from a sub-Saharan African setting. Methods: In 2011, 2013, and 2014, we obtained 6752 HIV-positive and 15415 HIV-negative test results from a population-based surveillance system in the KwaZulu-Natal province of South Africa. We quantified the PDV+ as the proportion of the 6752 HIV positive results with a viral load >1550 copies/mL and the PDVP as the proportion of the 6752 HIV-positive and 15415 HIV-negative results with a viral load >1550 copies/mL. Results: Between 2011 and 2014, the PDV+ decreased by 16.5 percentage points (pp) for women (from 71.8% to 55.3%) and 10.6 pp for men (from 77.8% to 67.2%). However, a steady rise in the overall HIV prevalence, from 26.7% to 32.4%, offset the declines in the PDV+ for both sexes. For women, the PDVP decreased by only 2.1 pp, from 21.3% to 19.2%, but for men, the PDVP actually increased by 1.6 pp, from 14.6% to 16.2%, over the survey period. Conclusions: The PDV+, which is currently being tracked under the UNAIDS 90-90-90 targets, may not be an accurate indicator of the potential for ongoing HIV transmission. There is a critical need for countries to monitor and report the prevalence of detectable viremia among all adults, irrespective of HIV status. PMID- 29186392 TI - Hawthorne effect reporting in orthodontic randomized controlled trials: truth or myth? Blessing or curse? AB - Objective: To investigate in 10 orthodontic journals how many randomized controlled trials (RCTs) considered the Hawthorne effect, and if considered, to determine whether it was related to the patients or the therapists involved in the trial and, finally, to discuss the Hawthorne effect in an educational way. Materials and methods: A search was performed on the Medline database, via PubMed, for publication type 'randomized controlled trial' published for each journal between 1 August 2007 and 31 July 2017. The American Journal of Orthodontics and Dentofacial Orthopedics, Angle Orthodontist, Australian Orthodontic Journal, Dental Press Journal of Orthodontics, European Journal of Orthodontics, Journal of Orthodontics, Journal of Orofacial Orthopedics, Korean Journal of Orthodontics, Orthodontics and Craniofacial Research and Progress in Orthodontics were assessed. Two independent reviewers extracted the data and identified whether the Hawthorne effect was considered or discussed in the articles and whether the Hawthorne effect was related to the behaviour of the patients, the therapists, or both. Results: The initial search generated 502 possible trials. After applying the inclusion and exclusion criteria, 290 RCTs were included and assessed. The Hawthorne effect was considered or discussed in 10 of 290 RCTs (3.4%), and all were related to the patients' and none to the therapists' behaviour. Conclusions: The Hawthorne effect reported in orthodontic RCTs was suboptimal. The researchers' lack of knowledge about this phenomenon is evident, despite evidence that the Hawthorne effect may cause over-optimistic results or false-positive bias. PMID- 29186390 TI - Direct Activation of Angiotensin II Type 2 Receptors Enhances Muscle Microvascular Perfusion, Oxygenation, and Insulin Delivery in Male Rats. AB - Angiotensin II receptors regulate muscle microvascular recruitment and the delivery of nutrients, oxygen, and insulin to muscle. Although angiotensin type 1 receptor antagonism increases muscle microvascular perfusion and insulin action, angiotensin type 2 receptor blockade markedly restricts muscle microvascular blood volume and decreases muscle delivery of insulin. To examine the effects of direct type 2 receptor stimulation using Compound 21 (C21) on microvascular perfusion, insulin delivery and action, and tissue oxygenation in muscle, overnight-fasted adult male rats were infused with C21 systemically. C21 potently increased microvascular blood volume without altering microvascular flow velocity or blood pressure, resulting in a net increase in microvascular blood flow in muscle. This was associated with a substantial increase in muscle interstitial oxygen saturation and insulin delivery into the skeletal and cardiac muscle. These effects were neutralized by coinfusion of the type 2 receptor antagonist or nitric oxide synthase inhibitor. Superimposing C21 infusion on insulin infusion increased insulin-mediated whole body glucose disposal by 50%. C21 significantly relaxed the preconstricted distal saphenous artery ex vivo. We have concluded that direct type 2 receptor stimulation markedly increases muscle microvascular perfusion through nitric oxide biosynthesis and enhances insulin delivery and action in muscle. These findings provide a physiologic mechanistic insight into type 2 receptor modulation of insulin action and suggest that type 2 receptor agonists might have therapeutic potential in the management of diabetes and its associated complications.

PMID- 29186395 TI - Bacillus amyloliquefaciens ssp. plantarum F11 isolated from Algerian salty lake as a source of biosurfactants and bioactive lipopeptides. AB - In this study, we identified a new Bacillus strain isolated from an Algerian salty lake that produces metabolites that are active against Gram-positive and Gram-negative bacteria, as well as fungal pathogens. The draft genome sequence of the strain is presented herein. Genome sequence analysis identified the strain to be B. amyloliquefaciens subspecies plantarum F11, and showed that the strain carries the gene clusters for the production of a number of bioactive and surface active compounds. These include the lipopeptides surfactin and fengycin, antibacterial polyketides macrolactin and bacillaene, and a putative novel lanthipeptide, among others. Through an activity-guided purification method using hydrophobic interaction chromatographic techniques, we confirmed the ability of the strain to produce fengycin lipopeptides. The identities of the isolated fengycin homologs were ascertained through tandem mass spectrometry. PMID- 29186393 TI - Inappropriate doses of direct oral anticoagulants in real-world clinical practice: prevalence and associated factors. A subanalysis of the FANTASIIA Registry. AB - Aims: To describe the prevalence and associated factors of inappropriate doses of direct oral anticoagulants (DOAC) in a national registry of patients of real clinical practice. Methods and results : Five hundred and thirty outpatients with atrial fibrillation treated with DOAC were included in a prospective, national, multicentre study. The appropriateness of the doses of DOAC was defined according to the recommendations of the European Heart Rhythm Association. Mean age was 73 +/- 9 years, with a 46% of women. Two hundred and sixty-seven patients were prescribed dabigatran, 190 rivaroxaban, and 73 apixaban. A total of 172 patients (32%) did not receive the appropriate dose: 93 patients received a lower dose (18%) and 79 patients a higher dose (15%). In the comparisons among the subgroups of inappropriately low, appropriate, and inappropriately high dose, we observed significant trends to older age (69 +/- 8 years vs. 73 +/- 10 years vs. 77 +/- 6 years), more frequent female sex (37% vs. 46% vs. 59%), antiplatelet drugs (5% vs. 8% vs. 25%), rivaroxaban (14% vs. 38% vs. 53%), and apixaban use (5% vs. 15% vs. 19%), higher CHAD2DS2-VASc (3.00 +/- 1.38 vs. 3.58 +/- 1.67 vs. 4.59 +/- 1.44) and HAS-BLED scores (1.83 +/- 0.87 vs. 1.92 +/- 1.07 vs. 2.47 +/- 1.13), lower body mass index (30 +/- 6 kg/m2 vs. 29 +/- 4 kg/m2 vs. 28 +/- 4 kg/m2) and glomerular filtration rate (74 +/- 27 mL/min vs. 70 +/- 22 mL/min vs. 63 +/- 16 mL/min), and lower frequency of dabigatran use (81% vs. 47% vs. 28%) (all comparisons P <= 0.01). Conclusion: In this real-life study, 32% of patients received an inappropriate dose of DOAC. Several clinical factors can identify patients at risk of this situation. PMID- 29186396 TI - Genome sequencing of Chlamydia trachomatis serovars E and F reveals substantial genetic variation. AB - Chlamydia trachomatis (Ctr) is a bacterial pathogen that causes ocular, urogenital and lymph system infections in humans. It is highly abundant and among its serovars, E, F and D are most prevalent in sexually transmitted disease. However, the number of publicly available genome sequences of the serovars E and F, and thereby our knowledge about the molecular architecture of these serovars, is low. Here we sequenced the genomes of six E and F clinical isolates and one E lab strain, in order to study the genetic variance in these serovars. As observed before, the genomic variation inside the Ctr genomes is very low and the phylogenetic placement in comparison to publicly available genomes is as expected by ompA gene serotyping. However, we observed a large InDel carrying four to five open reading frames in one clinical E sample and in the E lab strain. We have also observed substantial variation on nucleotide and amino acid levels, especially in membrane proteins and secreted proteins. Furthermore, these two groups of proteins are also target for recombination events. One clinical F isolate was genetically heterogeneous and revealed the highest differences on nucleotide level in the pmpE gene. PMID- 29186397 TI - Images of atrial giant cell myocarditis.

PMID- 29186400 TI - Metabolites associated with risk of developing mobility disability in the Health, Aging and Body Composition Study. AB - Background: Metabolic pathways that give rise to functional decline and mobility disability in older adults are incompletely understood. Methods: To identify metabolic perturbations that may impact functional decline, non-targeted metabolomics was used to measure 350 metabolites in baseline plasma from 313 black men in the Health ABC Study (median age 74 years). Usual gait speed was measured over 20 meters. Cross-sectional relationships between gait speed and metabolites were explored with partial correlations adjusted for age, study site and smoking status. Risk of incident mobility disability (2 consecutive reports of severe difficulty walking 1/4 mile or climb 10 stairs) over 13 years of follow up was explored with cox regression models among 307 men who were initially free of mobility disability. Significance was determined at p<=0.01 and q (false discovery rate) <=0.30. Results: Two metabolites were correlated with gait speed; salicylurate (r=-0.19), and 2-hydroxyglutarate (r=-0.18). Metabolites of amino acids and amino acid degredation (indoxy sulfate; HR=1.48, 95% CI 1.09-2.03, symmetric dimethylarginine; HR=3.58, 95% CI=1.57-8.15, N-carbamoyl beta-alanine; HR=1.91, 95% CI=1.16-3.14, quinolinate; HR 2.56, 95% CI 1.65-3.96) and metabolites related to kidney function (aforementioned symmetric dimethylarginine and indoxy sulfate as well as creatinine; HR 5.91, 95% CI 2.06-16.9, inositol; HR 2.70, 95% CI 1.47-4.97) were among the 23 metabolites associated with incident mobility disability. Conclusions: This study highlights the potential role of amino acid derivatives and products and kidney function early in the development of mobility disability and suggests metabolic profiles could help identify individuals at risk of functional decline. PMID- 29186399 TI - Construction of PRDM9 allele-specific recombination maps in cattle using large scale pedigree analysis and genome-wide single sperm genomics. AB - PRDM9 contributes to hybrid sterility and species evolution. However, its role is to be confirmed in cattle, a major domesticated livestock species. We previously found an association near PRDM9 with cattle recombination features, but the causative variants are still unknown. Using millions of genotyped cattle with pedigree information, we characterized five PRDM9 alleles and generated allele specific recombination maps. By examining allele-specific recombination patterns, we observed the impact of PRDM9 on global distribution of recombination, especially in the two ends of chromosomes. We also showed strong associations between recombination hotspot regions and functional mutations within PRDM9 zinc finger domain. More importantly, we found one allele of PRDM9 to be very different from others in both protein composition and recombination landscape, indicating the causative role of this allele on the association between PRDM9 and cattle recombination. When comparing recombination maps from sperm and pedigree data, we observed similar genome-wide recombination patterns, validating the quality of pedigree-based results. Collectively, these evidence supported PRDM9 alleles as causal variants for the reported association with cattle recombination. Our study comprehensively surveyed the bovine PRDM9 alleles, generated allele-specific recombination maps, and expanded our understanding of the role of PRDM9 on genome distribution of recombination.

Insights from real world clinical practice in the DECODE CRT-D analysis. AB - Aim: Ventricular tachycardia (VT)/ventricular fibrillation (VF) occurrence after cardiac resynchronization therapy-defibrillator (CRT-D) replacement is unknown; hence, there is no practical guideline to recommend either CRT-D or CRT-pacemaker at the time of device replacement. We observed the 1-year VT/VF occurrence after CRT-D replacement in a subanalysis of the Detect Long-term Complications after ICD Replacement (DECODE) registry. Methods and results: A total of 332 consecutive patients who had undergone CRT-D replacement from 2013 to 2015 were enrolled in 36 Italian centres. The primary endpoint was the number of patients with any appropriate implantable cardioverter-defibrillator (ICD) interventions during 12-month follow-up. The secondary endpoint comprised death from any cause and appropriate ICD interventions. At replacement, 214 (64.5%) patients had a left ventricular ejection fraction <= 35% and 138 (41.6%) patients had a secondary prevention indication for ICD. Seventy (21.1%) patients had no longer indication to ICD therapy. During a median follow-up period of 406.5 (362-533) days, VT/VF requiring therapy delivery occurred in 57 (17%) patients, specifically in 7% of those who no longer had an ICD indication. On multivariate analysis, number of criteria for ICD replacement independently predicted appropriate ICD intervention during follow-up [hazard ratio (HR) = 1.62, 95% confidence interval (CI) 1.07-2.46; log-rank P = 0.02]. The combined endpoint of death from any cause or appropriate ICD therapy occurred in 76 (23%) patients. Only NYHA class remained associated with this combined endpoint (HR = 1.97, 95% CI 1.23-3.14; P = 0.005). Conclusions: The DECODE registry showed the 'real world' experience of CRT-D recipients approaching device replacement, in which 7% of patients who no longer had an indication for ICD therapy experienced appropriate ICD interventions. PMID- 29186402 TI - In vitro and in vivo activity of single and dual antimicrobial agents against KPC producing Klebsiella pneumoniae. AB - Objectives: Options for treatment of infections due to KPC-producing Klebsiella pneumoniae are limited and combination therapy is often recommended. In this report, the in vitro and in vivo activity of potential therapeutic agents and combinations was assessed against four KPC-producing K. pneumoniae isolates. Methods: Using clinically relevant concentrations, time-kill experiments and the Galleria mellonella model of infection were used to examine the activity of polymyxin B, ceftazidime/avibactam, meropenem, rifampicin and amikacin alone and in combination. Results: Two K. pneumoniae isolates were resistant to polymyxin B and had ceftazidime/avibactam MICs of 8/4 mg/L. When ceftazidime/avibactam was combined with either amikacin or meropenem, synergy was observed in vitro, and these combinations were associated with improved survival in the in vivo model. Improved survival was also observed using higher doses of ceftazidime/avibactam. The other two K. pneumoniae isolates were susceptible to polymyxin B and had lower (1/4 mg/L) MICs of ceftazidime/avibactam. For these two isolates, bactericidal activity was observed in vitro at ceftazidime/avibactam concentrations four times the MIC. At one-quarter of the MIC, synergy was observed when ceftazidime/avibactam was combined with meropenem. In the in vivo model with the two susceptible isolates, improved survival rates were observed following therapy with ceftazidime/avibactam monotherapy. For all four isolates, polymyxin B with or without rifampicin or meropenem performed poorly in the in vivo model. Conclusions: Pending clinical studies, combining ceftazidime/avibactam with another agent (e.g. a carbapenem) should be considered when treating serious infections due to these pathogens, particularly for isolates with ceftazidime/avibactam MICs near the susceptibility breakpoint. PMID- 29186403 TI - Associations Between Enteral Colonization With Gram-Negative Bacteria and Intensive Care Unit-Acquired Infections and Colonization of the Respiratory Tract. AB - Background: Enteral and respiratory tract colonization with gram-negative bacteria may lead to subsequent infections in critically ill patients. We aimed to clarify the interdependence between gut and respiratory tract colonization and their associations with intensive care unit (ICU)-acquired infections in patients receiving selective digestive tract decontamination (SDD). Methods: Colonization status of the rectum and respiratory tract was determined using twice-weekly microbiological surveillance in mechanically ventilated subjects receiving SDD between May 2011 and June 2015 in a tertiary medical-surgical ICU in the Netherlands. Acquisition of infections was monitored daily by dedicated observers. Marginal structural models were used to determine the associations between gram-negative rectal colonization and respiratory tract colonization, ICU acquired gram-negative infection, and ICU-acquired gram-negative bacteremia. Results: Among 2066 ICU admissions, 1157 (56.0%) ever had documented gram negative carriage in the rectum during ICU stay. Cumulative incidences of ICU acquired gram-negative infection and bacteremia were 6.0% (n = 124) and 2.1% (n = 44), respectively. Rectal colonization was an independent risk factor for both respiratory tract colonization (cause-specific hazard ratio [CSHR], 2.93 [95% confidence interval {CI}, 2.02-4.23]) and new gram-negative infection in the ICU (CSHR, 3.04 [95% CI, 1.99-4.65]). Both rectal and respiratory tract colonization were associated with bacteremia (CSHR, 7.37 [95% CI, 3.25-16.68] and 2.56 [95% CI, 1.09-6.03], respectively). Similar associations were observed when Enterobacteriaceae and glucose nonfermenting gram-negative bacteria were analyzed separately. Conclusions: Gram-negative rectal colonization tends to be stronger associated with subsequent ICU-acquired gram-negative infections than gram negative respiratory tract colonization. Gram-negative rectal colonization seems hardly associated with subsequent ICU-acquired gram-negative respiratory tract colonization.

AB - Wolbachia (Alphaproteobacteria, Rickettsiales) is the most common, and arguably one of the most important inherited symbionts. Molecular differentiation of Wolbachia strains is routinely performed with a set of five multilocus sequence typing (MLST) markers. However, since its inception in 2006, the performance of MLST in Wolbachia strain typing has not been assessed objectively. Here, we evaluate the properties of Wolbachia MLST markers and compare it to 252 other single copy loci present in the genome of most Wolbachia strains. Specifically, we investigated how well MLST performs at strain differentiation, at reflecting genetic diversity of strains, and as phylogenetic marker. We find that MLST loci are outperformed by other loci at all tasks they are currently employed for, and thus that they do not reflect the properties of a Wolbachia strain very well. We argue that whole genome typing approaches should be used for Wolbachia typing in the future. Alternatively, if few loci approaches are necessary, we provide a characterisation of 252 single copy loci for a number a criteria, which may assist in designing specific typing systems or phylogenetic studies.

PMID- 29186407 TI - Surgical ablation of atrial fibrillation: a systematic review and meta-analysis of randomized controlled trials. AB - Aims: The aim of this review was to assess the effect of concomitant surgical atrial fibrillation (AF) ablation on postoperative freedom from AF and patient important outcomes. Methods and results: We searched Cochrane CENTRAL, MEDLINE, and EMBASE databases from inception to May 2016 for randomized controlled trials (RCTs) evaluating surgical AF ablation using any lesion set vs. no surgical AF ablation in adults with AF undergoing cardiac surgery. We performed screening, risk-of-bias evaluation, and data collection independently and in duplicate. We evaluated risk of bias with the modified Cochrane tool, quality of evidence using GRADE framework, and pooled data with a random-effects model. Of the 23 included studies, only one was considered at low risk of bias. Surgical AF ablation was associated with more freedom from AF at 12 months [relative risk (RR) = 2.32, 95% confidence interval (CI) 1.92-2.80; P < 0.001, low quality]. However, no significant difference was seen in mortality (RR = 1.07, 95% CI 0.72-1.52; P = 0.41, moderate quality), stroke (RR = 1.19, 95% CI 0.59-2.39; P = 0.63, moderate quality), or pacemaker implantation (RR = 1.28, 95% CI 0.85-1.95; P = 0.24, high quality). Comparing biatrial and left-sided lesion sets showed no difference in mortality (P-interaction = 0.60) or stroke (P-interaction = 0.12). At 12 months, biatrial procedures led to more freedom from AF (RR = 2.80, 95% CI 2.13-3.68; P < 0.0001) when compared with left-sided ablation (RR = 2.00, 95% CI 1.68-2.39; P < 0.0001) (P-interaction = 0.04) Biatrial procedures appear to increase the risk for pacemaker (RR = 2.68, 95% CI 1.41-5.11; P = 0.002) compared with no ablation while left-sided ablation does not (RR = 1.08, 95% CI 0.67-1.74; P = 0.76) (P interaction = 0.03). Conclusion: Surgical AF ablation during cardiac surgery improves freedom from AF. However, impact on patient-important outcomes including mortality and stroke has not shown statistical significance in current RCT evidence. Biatrial compared with left-sided lesion sets showed no difference in mortality or stroke but were associated with significantly increased freedom from AF and risk for pacemaker requirement. PMID- 29186408 TI - A significant therapeutic effect of immunoglobulins administered alone, or in combination with conventional chemotherapy, in experimental pulmonary tuberculosis caused by drug-sensitive or drug-resistant strains. AB - The recommended chemotherapy for drug-sensitive tuberculosis (TB) consists of four different antibiotics administrated for 6 months. This long treatment leads to significant compliance problems and consequently to recrudescence of the disease and to the development of multidrug-resistant (MDR) strains. Thus, new alternatives are needed to shorten or simplify the treatment of TB. Antibodies have therapeutic effects in animal models of TB, so their use as adjuvants in drug-sensitive and MDR TB is an interesting alternative. To assess the effect of antibodies, BALB/c mice with active late disease 60 days after infection with drug-sensitive TB strain H37Rv were treated with intravenous immunoglobulin (IVIg), alone or in combination with conventional chemotherapy. When compared with control non-treated animals, IVIg alone produced a significantly decreased burden of pulmonary bacilli. This decrease was even greater when IVIg was used in combination with conventional chemotherapy. The combined therapy also significantly reduced tissue damage (pneumonia) when compared to infected animals treated only with antibiotics. IVIg treatment also caused decreased bacillary burdens in mice infected with an MDR strain. In vitro experiments suggested that improving phagocytosis by efficient opsonization is perhaps the principal mechanism of this beneficial therapeutic effect.

PMID- 29186410 TI - Induction of a viable but non-culturable state in Salmonella Typhimurium by thermosonication and factors affecting resuscitation. AB - The objective of this work was to analyze the effects of thermosonication (TS) on induction of a viable but non-culturable (VBNC) state in Salmonella Typhimurium and to examine incubation factors affecting subsequent resuscitation of cells. A TS treatment of 380 W at 53 degrees C for 30 min induced the VBNC state in S. Typhimurium cells in beef peptone yeast (BPY) broth, apple/carrot juice, physiological saline and phosphate buffer solution. The logarithmic and decline phases of growth were more sensitive to the TS treatment compared to stationary phase cells. Meanwhile, VBNC S. Typhimurium could be resuscitated back to culturable cells by using suitable incubation temperatures and media. Addition of Tween 20 hindered resuscitation compared to the use of BPY medium alone. The optimal growth temperature (i.e. 37 degrees C) was the most suitable temperature to resuscitate cells from the VBNC state. The VBNC incidence index decreased with the addition of sodium pyruvate during TS treatment, as it accelerated resuscitation. The results demonstrated that free radicals produced during TS processing and the growth phase of cells affected induction of the VBNC state in S. Typhimurium. Hence, the kinds and amounts of free radicals generated during TS treatment should be analyzed in the future. PMID- 29186411 TI - Late onset of pneumothorax after bronchoscopic lung volume reduction due to migration of a nitinol coil. AB - The use of Endobronchial coils are a relatively new brochoscopic technique for lung volume reduction. They appear to be safe and effective in improving quality of life, reducing morbidity and mortality related to the primary disease, while avoiding the many risks of morbidity and mortality associated with surgery. Nevertheless, some complications, such as pneumothorax, are relatively common in the periprocedural period. We describe a case of pneumothorax that occurred several days after brochoscopic technique for lung volume reduction due to direct perforation of the visceral pleura by a coil. The patient presented with a large pneumothorax associated with significant air leak, requiring surgical intervention. Exploration of the chest cavity showed a pleural tear caused by a coil. To our knowledge, this is an adverse event that has never been described before, suggesting the possible migration of the coil from the original position. PMID- 29186412 TI - Genomic characterization and comparative analysis of Leptospira interrogans serogroup Australis isolated from swine. AB - The Leptospira interrogans serogroup Australis is traditionally described as pathogenic for swine although animals usually present low serologic response and mild clinical signs. The first isolation of a Leptospira interrogans serogroup Australis strain from swine, in Brazil, was recently described. Herein we present the genomic characterization of this strain (SU5) and further comparison with the Leptospira serovars reference genomes available in the GenBank database. The SU5 strain was characterized with sequence types previously described in a serogroup Australis isolated from human and presented a new ST98 that is thus far exclusively of the Brazilian porcine L. interrogans serogroup Australis. Even though the SU5 strain presented higher similarity with the American porcine serogroup Australis strain PigK151, as expected, it also presented sequences blocks in both chromosomes which are absent in the genomes of the studied Leptospira serovars. These regions are flanked by insertion sequences and transposases genes, suggesting the existence of inter- and intra-serogroup genomic variability due to mobile elements transferring. This genomic plasticity has already been demonstrated for pathogenic Leptospira species; nevertheless, there is still a limited understanding of the relationship between genome organization and content and the divergence of Leptospira serogroups and serovars that needs to be further elucidated. PMID- 29186413 TI - Antenatal paternal adjustment and paternal attitudes after infertility treatment. AB - STUDY QUESTION: Do mode of conception [ART versus Natural (NC)] and depression have an interactive effect on antenatal paternal adjustment and paternal attitudes? SUMMARY ANSWER: Depression increased the negative effect of ART on antenatal paternal adjustment and paternal attitudes, specifically on antenatal marital relationship satisfaction. WHAT IS KNOWN ALREADY: Research on antenatal paternal adjustment and paternal attitudes after ART is scarce and has produced inconsistent results. STUDY DESIGN, SIZE, DURATION: This cross-sectional study assessed 197 primiparous men (71 ART and 126 NC) during their partner's second trimester of gestation. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants were derived from three larger longitudinal studies recruited at public Health Services in Northern Portugal. All men, for who this was their first child and had filled in a socio-demographic questionnaire, measures of depression and anxiety, and antenatal paternal adjustment and paternal attitudes were selected. MAIN RESULTS AND THE ROLE OF CHANCE: An interaction effect of mode of conception and depression was found on antenatal paternal adjustment and paternal attitudes. ART men showing high depressive symptomatology had lower antenatal marital relationship satisfaction than ART men showing low depressive symptomatology and NC men showing high or low depressive symptomatology. LIMITATIONS, REASONS FOR CAUTION: Due to the cross-sectional design of this study and the small sample size in the depression groups, the findings should be interpreted with caution. WIDER IMPLICATIONS OF THE FINDINGS: Specialized psychological support should be available for ART men screened with high depressive symptomatology as part of routine prenatal care appointments. STUDY FUNDING/COMPETING INTEREST(S): This study was conducted at Psychology Research Centre (UID/PSI/ 01662/2013), University of Minho, and at the Unidade de Investigacao em Epidemiologia Instituto de Saude Publica da Universidade do Porto (EPIUnit) (UID/DTP/04750/2013). It was supported by the Foundation for Science and Technology (Portuguese Ministry of Education and Science) through National funds and co-financed by FEDER through COMPETE2020 under the PT2020 Partnership Agreement (POCI-01-0145-FEDER-007653) and through the Operational Programme Factors of Competitiveness-COMPETE within the project 'Health, Governance and Accountability in Embryo Research: Couples' Decisions About the Fates of Embryos' (FCOMP-01-0124-FEDER-014453), the FCT Investigator contract IF/01674/2015 and PhD grants (SFRH/BD/115048/2016, SFRH/BD/75807/2011 and SFRH/BD/40146/2007).

AB - Heart failure (HF) is often accompanied by atrioventricular (AV) conduction disturbance, represented by prolongation of the PR interval on the electrocardiogram. Studies suggest that PR prolongation exists in at least 10% of HF patients, and it seems more prevalent in the presence of prolonged QRS duration. A prolonged PR interval may result in elevated left ventricular (LV) end-diastolic pressure, diastolic mitral regurgitation, and reduced LV pump function. This seems especially the case in patients with heart disease, in whom it is associated with an increased risk for atrial fibrillation, advanced AV heart block, HF, and death. These findings point towards the importance of proper AV coupling in HF patients. A few studies, strongly differing in design, suggest that restoration of AV coupling in patients with PR prolongation by pacing improves cardiac function and clinical outcomes. These observations argue for AV dromotropathy as a potential target for pacing therapy, but other studies show inconsistent results. Given its potential clinical implications, restoration of AV coupling by pacing warrants further investigation. Additional possible future research goals include assessing different techniques to measure compromised AV coupling, determine the best site(s) of ventricular pacing, and assess a potential influence of diastolic mitral regurgitation in the efficacy of such therapy. PMID- 29186414 TI - Local sympathetic denervation attenuates myocardial inflammation and improves cardiac function after myocardial infarction in mice. AB - Aims: Cardiac inflammation has been suggested to be regulated by the sympathetic nervous system (SNS). However, due to the lack of methodology to surgically eliminate the myocardial SNS in mice, neuronal control of cardiac inflammation remains ill-defined. Here, we report a procedure for local cardiac sympathetic denervation in mice and tested its effect in a mouse model of heart failure post myocardial infarction. Methods and results: Upon preparation of the carotid bifurcation, the right and the left superior cervical ganglia were localized and their pre- and postganglionic branches dissected before removal of the ganglion. Ganglionectomy led to an almost entire loss of myocardial sympathetic innervation in the left ventricular anterior wall. When applied at the time of myocardial infarction (MI), cardiac sympathetic denervation did not affect acute myocardial damage and infarct size. In contrast, cardiac sympathetic denervation significantly attenuated chronic consequences of MI, including myocardial inflammation, myocyte hypertrophy, and overall cardiac dysfunction. Conclusion: These data suggest a critical role for local sympathetic control of cardiac inflammation. Our model of myocardial sympathetic denervation in mice should prove useful to further dissect the molecular mechanisms underlying cardiac neural control. PMID- 29186416 TI - A Randomized Dose-Ranging Study of Neuropeptide Y in Patients with Posttraumatic Stress Disorder. AB - Background: Anxiety and trauma-related disorders are among the most prevalent and disabling medical conditions in the United States, and posttraumatic stress disorder in particular exacts a tremendous public health toll. We examined the tolerability and anxiolytic efficacy of neuropeptide Y administered via an intranasal route in patients with posttraumatic stress disorder. Methods: Twenty six individuals were randomized in a cross-over, single ascending dose study into 1 of 5 cohorts: 1.4 mg (n=3), 2.8 mg (n=6), 4.6 mg (n=5), 6.8 mg (n=6), and 9.6 mg (n=6). Each individual was dosed with neuropeptide Y or placebo on separate treatment days 1 week apart in random order under double-blind conditions. Assessments were conducted at baseline and following a trauma script symptom provocation procedure subsequent to dosing. Occurrence of adverse events represented the primary tolerability outcome. The difference between treatment conditions on anxiety as measured by the Beck Anxiety Inventory and the State Trait Anxiety Inventory immediately following the trauma script represented efficacy outcomes. Results: Twenty-four individuals completed both treatment days. Neuropeptide Y was well tolerated up to and including the highest dose. There was a significant interaction between treatment and dose; higher doses of neuropeptide Y were associated with a greater treatment effect, favoring neuropeptide Y over placebo on Beck Anxiety Inventory score (F1,20=4.95, P=.038). There was no significant interaction for State-Trait Anxiety Inventory score. Conclusions: Our study suggests that a single dose of neuropeptide Y is well tolerated up to 9.6 mg and may be associated with anxiolytic effects. Future studies exploring the safety and efficacy of neuropeptide Y in stress-related disorders are warranted. The reported study is registered at: http://clinicaltrials.gov (ID: NCT01533519). PMID- 29186417 TI - Examining influences on speaking up among critical care healthcare providers in the United Arab Emirates. AB - Objective: Assess perceived barriers to speaking up and to provide recommendations for reducing barriers to reporting adverse events and near misses. Design, setting, participants, intervention: A six-item survey was administered to critical care providers in 19 Intensive Care Units in Abu Dhabi as part of an organizational safety and quality improvement effort. Main outcome measures: Questions elicited perspectives about influences on reporting, perceived barriers and recommendations for conveying patient safety as an organizational priority. Qualitative thematic analyses were conducted for open ended questions. Results: A total of 1171 participants were invited to complete the survey and 639 responded (response rate = 54.6%). Compared to other stakeholders (e.g. the media, public), a larger proportion of respondents 'agreed/strongly agreed' that corporate health system leadership and the health regulatory authority encouraged and supported error reporting (83%; 75%), and had the most influence on their decisions to report (81%; 74%). 29.5% of respondents cited fear of repercussion as a barrier, and 21.3% of respondents indicated no barriers to reporting. Barriers included perceptions of a culture of blame and issues with reporting procedures. Recommendations to establish patient safety as an organizational priority included creating supportive environments to discuss errors, hiring staff to advocate for patient safety, and implementing policies to standardize clinical practices and streamline reporting procedures. Conclusions: Influences on reporting perceived by providers in the UAE were similar to those in the US and other countries. These findings highlight the roles of corporate leadership and regulators in developing non-punitive environments where reporting is a valuable and safe activity.

AB - Background: Antheraea yamamai, also known as the Japanese oak silk moth, is a wild species of silk moth. Silk produced by A. yamamai, referred to as tensan silk, shows different characteristics such as thickness, compressive elasticity, and chemical resistance compared with common silk produced from the domesticated silkworm, Bombyx mori. Its unique characteristics have led to its use in many research fields including biotechnology and medical science, and the scientific as well as economic importance of the wild silk moth continues to gradually increase. However, no genomic information for the wild silk moth, including A. yamamai, is currently available. Findings: In order to construct the A. yamamai genome, a total of 147G base pairs using Illumina and Pacbio sequencing platforms were generated, providing 210-fold coverage based on the 700-Mb estimated genome size of A. yamamai. The assembled genome of A. yamamai was 656 Mb (>2 kb) with 3675 scaffolds, and the N50 length of assembly was 739 Kb with a 34.07% GC ratio. Identified repeat elements covered 37.33% of the total genome, and the completeness of the constructed genome assembly was estimated to be 96.7% by Benchmarking Universal Single-Copy Orthologs v2 analysis. A total of 15 481 genes were identified using Evidence Modeler based on the gene prediction results obtained from 3 different methods (ab initio, RNA-seq-based, known-gene-based) and manual curation. Conclusions: Here we present the genome sequence of A. yamamai, the first genome sequence of the wild silk moth. These results provide valuable genomic information, which will help enrich our understanding of the molecular mechanisms relating to not only specific phenotypes such as wild silk itself but also the genomic evolution of Saturniidae. PMID- 29186419 TI - Management of ventricular tachycardia in the ablation era: results of the European Heart Rhythm Association Survey. AB - Patients with sustained ventricular tachycardia (VT) are at risk of sudden death. Treatment options for VT include antiarrhythmic drug therapy, insertion of an implantable cardioverter-defibrillator, and catheter ablation. Evidence on indications for VT ablation, timing, ablation strategies, and periprocedural management is sparse. The aim of this European Heart Rhythm Association (EHRA) survey was to evaluate clinical practice regarding management of VT among the European countries. An electronic questionnaire was sent to members of the EHRA Electrophysiology Research Network. Responses were received from 88 centres in 12 countries. The results have shown that management of VTs is very heterogeneous across the participating centres. Indications, periprocedural management, and ablation strategies vary substantially. This EP Wire survey has revealed that catheter ablation is the first-line therapy for the treatment of recurrent monomorphic stable VT in patients without structural heart disease as well as in patients with ischaemic cardiomyopathy and impaired left ventricular ejection fraction in the majority of centres. Furthermore, in patients with ischaemic cardiomyopathy and the first episode of monomorphic VT, most centres (62.0%) performed catheter ablation. On the contrary, in patients with non-ischaemic cardiomyopathy, amiodarone (41.4%) and catheter ablation (37.1%) are used in a very similar proportion. Ablation strategies, endpoints, and post-ablation antithrombotic management vary substantially among European centres. PMID- 29186421 TI - Expanding Hospital Human Immunodeficiency Virus Testing in the Bronx, New York and Washington, District of Columbia: Results From the HPTN 065 Study. AB - Background: Human immunodeficiency virus (HIV) testing is critical for both HIV treatment and prevention. Expanding testing in hospital settings can identify undiagnosed HIV infections. Methods: To evaluate the feasibility of universally offering HIV testing during emergency department (ED) visits and inpatient admissions, 9 hospitals in the Bronx, New York and 7 in Washington, District of Columbia (DC) undertook efforts to offer HIV testing routinely. Outcomes included the percentage of encounters with an HIV test, the change from year 1 to year 3, and the percentages of tests that were HIV-positive and new diagnoses. Results: From 1 February 2011 to 31 January 2014, HIV tests were conducted during 6.5% of 1621016 ED visits and 13.0% of 361745 inpatient admissions in Bronx hospitals and 13.8% of 729172 ED visits and 22.0% of 150655 inpatient admissions in DC. From year 1 to year 3, testing was stable in the Bronx (ED visits: 6.6% to 6.9%; inpatient admissions: 13.0% to 13.6%), but increased in DC (ED visits: 11.9% to 15.8%; inpatient admissions: 19.0% to 23.9%). In the Bronx, 0.4% (408) of ED HIV tests were positive and 0.3% (277) were new diagnoses; 1.8% (828) of inpatient tests were positive and 0.5% (244) were new diagnoses. In DC, 0.6% (618) of ED tests were positive and 0.4% (404) were new diagnoses; 4.9% (1349) of inpatient tests were positive and 0.7% (189) were new diagnoses. Conclusions: Hospitals consistently identified previously undiagnosed HIV infections, but universal offer of HIV testing proved elusive. PMID- 29186422 TI - Cohort Profile: The Korean Cancer Prevention Study-II (KCPS-II) Biobank. PMID- 29186424 TI - NALT M cells are important for immune induction for the common mucosal immune system. AB - Nasopharynx-associated lymphoid tissue (NALT) is one of the major constituents of the mucosa-associated lymphoid tissue (MALT), and has the ability to induce antigen-specific immune responses. However, the molecular mechanisms responsible for antigen uptake from the nasal cavity into the NALT remain largely unknown. Immunohistochemical analysis showed that CCL9 and CCL20 were co-localized with glycoprotein 2 (GP2) in the epithelium covering NALT, suggesting the existence of M cells in NALT. In analogy with the reduced number of Peyer's patch M cells in CCR6-deficient mice, the number of NALT M cells was drastically decreased in CCR6 deficient mice compared with the wild-type mice. Translocation of nasally administered Salmonella enterica serovar Typhimurium into NALT via NALT M cells was impaired in CCR6-deficient mice, whereas S. Typhimurium demonstrated consistent co-localization with NALT M cells in wild-type mice. When wild-type mice were nasally administered with an attenuated vaccine strain of S. Typhimurium, the mice were protected from a subsequent challenge with wild-type S. Typhimurium. Antigen-specific fecal and nasal IgA was detected after nasal immunization with the attenuated vaccine strain of S. Typhimurium only in wild type mice but not in CCR6-deficient mice. Taken together, these observations demonstrate that NALT M cells are important as a first line of defense against infection by enabling activation of the common mucosal immune system (CMIS). PMID- 29186423 TI - Improving amphibian genomic resources: a multitissue reference transcriptome of an iconic invader. AB - Background: Cane toads (Rhinella marina) are an iconic invasive species introduced to 4 continents and well utilized for studies of rapid evolution in introduced environments. Despite the long introduction history of this species, its profound ecological impacts, and its utility for demonstrating evolutionary principles, genetic information is sparse. Here we produce a de novo transcriptome spanning multiple tissues and life stages to enable investigation of the genetic basis of previously identified rapid phenotypic change over the introduced range. Findings: Using approximately 1.9 billion reads from developing tadpoles and 6 adult tissue-specific cDNA libraries, as well as a transcriptome assembly pipeline encompassing 100 separate de novo assemblies, we constructed 62 202 transcripts, of which we functionally annotated ~50%. Our transcriptome assembly exhibits 90% full-length completeness of the Benchmarking Universal Single-Copy Orthologs data set. Robust assembly metrics and comparisons with several available anuran transcriptomes and genomes indicate that our cane toad assembly is one of the most complete anuran genomic resources available. Conclusions: This comprehensive anuran transcriptome will provide a valuable resource for investigation of genes under selection during invasion in cane toads, but will also greatly expand our general knowledge of anuran genomes, which are underrepresented in the literature. The data set is publically available in NCBI and GigaDB to serve as a resource for other researchers.

AB - Background: Maize (Zea mays ssp. mays) is 1 of 3 crops, along with rice and wheat, responsible for more than one-half of all calories consumed around the world. Increasing the yield and stress tolerance of these crops is essential to meet the growing need for food. The cost and speed of plant phenotyping are currently the largest constraints on plant breeding efforts. Datasets linking new types of high-throughput phenotyping data collected from plants to the performance of the same genotypes under agronomic conditions across a wide range of environments are essential for developing new statistical approaches and computer vision-based tools. Findings: A set of maize inbreds-primarily recently off patent lines-were phenotyped using a high-throughput platform at University of Nebraska-Lincoln. These lines have been previously subjected to high-density genotyping and scored for a core set of 13 phenotypes in field trials across 13 North American states in 2 years by the Genomes 2 Fields Consortium. A total of 485 GB of image data including RGB, hyperspectral, fluorescence, and thermal infrared photos has been released. Conclusions: Correlations between image-based measurements and manual measurements demonstrated the feasibility of quantifying variation in plant architecture using image data. However, naive approaches to measuring traits such as biomass can introduce nonrandom measurement errors confounded with genotype variation. Analysis of hyperspectral image data demonstrated unique signatures from stem tissue. Integrating heritable phenotypes from high-throughput phenotyping data with field data from different environments can reveal previously unknown factors that influence yield plasticity.

PMID- 29186427 TI - Insulinlike Growth Factor-Binding Protein-1 Improves Vascular Endothelial Repair in Male Mice in the Setting of Insulin Resistance. AB - Insulin resistance is associated with impaired endothelial regeneration in response to mechanical injury. We recently demonstrated that insulinlike growth factor-binding protein-1 (IGFBP1) ameliorated insulin resistance and increased nitric oxide generation in the endothelium. In this study, we hypothesized that IGFBP1 would improve endothelial regeneration and restore endothelial reparative functions in the setting of insulin resistance. In male mice heterozygous for deletion of insulin receptors, endothelial regeneration after femoral artery wire injury was enhanced by transgenic expression of human IGFBP1 (hIGFBP1). This was not explained by altered abundance of circulating myeloid angiogenic cells. Incubation of human endothelial cells with hIGFBP1 increased integrin expression and enhanced their ability to adhere to and repopulate denuded human saphenous vein ex vivo. In vitro, induction of insulin resistance by tumor necrosis factor alpha (TNFalpha) significantly inhibited endothelial cell migration and proliferation. Coincubation with hIGFBP1 restored endothelial migratory and proliferative capacity. At the molecular level, hIGFBP1 induced phosphorylation of focal adhesion kinase, activated RhoA and modulated TNFalpha-induced actin fiber anisotropy. Collectively, the effects of hIGFBP1 on endothelial cell responses and acceleration of endothelial regeneration in mice indicate that manipulating IGFBP1 could be exploited as a putative strategy to improve endothelial repair in the setting of insulin resistance. PMID- 29186428 TI - Genome-wide meta-analysis identifies novel determinants of circulating serum progranulin. AB - Progranulin is a secreted protein with important functions in processes including immune and inflammatory response, metabolism and embryonic development. The present study aimed at identification of genetic factors determining progranulin concentrations. We conducted a genome-wide association meta-analysis for serum progranulin in three independent cohorts from Europe: Sorbs (N = 848) and KORA (N = 1628) from Germany and PPP-Botnia (N = 335) from Finland (total N = 2811). Single nucleotide polymorphisms (SNPs) associated with progranulin levels were replicated in two additional German cohorts: LIFE-Heart Study (Leipzig; N = 967) and Metabolic Syndrome Berlin Potsdam (Berlin cohort; N = 833). We measured mRNA expression of genes in peripheral blood mononuclear cells (PBMC) by micro-arrays and performed mRNA expression quantitative trait and expression-progranulin association studies to functionally substantiate identified loci. Finally, we conducted siRNA silencing experiments in vitro to validate potential candidate genes within the associated loci. Heritability of circulating progranulin levels was estimated at 31.8% and 26.1% in the Sorbs and LIFE-Heart cohort, respectively. SNPs at three loci reached study-wide significance (rs660240 in CELSR2-PSRC1-MYBPHL-SORT1, rs4747197 in CDH23-PSAP and rs5848 in GRN) explaining 19.4%/15.0% of the variance and 61%/57% of total heritability in the Sorbs/LIFE Heart Study. The strongest evidence for association was at rs660240 (P = 5.75 * 10-50), which was also associated with mRNA expression of PSRC1 in PBMC (P = 1.51 * 10-21). Psrc1 knockdown in murine preadipocytes led to a consecutive 30% reduction in progranulin secretion. In conclusion, the present meta-GWAS combined with mRNA expression identified three loci associated with progranulin and supports the role of PSRC1 in the regulation of progranulin secretion. PMID- 29186429 TI - Extracellular matrix in uterine leiomyoma pathogenesis: a potential target for future therapeutics. AB - BACKGROUND: Uterine leiomyoma (also known as fibroid or myoma) is the most common benign tumor of the uterus found in women of reproductive age. It is not usually fatal but can produce serious clinical symptoms, including excessive uterine bleeding, pelvic pain or pressure, infertility and pregnancy complications. Due to lack of effective medical treatments surgery has been a definitive choice for the management of this tumor. OBJECTIVE AND RATIONALE: Extracellular matrix (ECM) accumulation and remodeling are thought to be crucial for fibrotic diseases such as uterine leiomyoma. Indeed, ECM plays important role in forming the bulk structure of leiomyoma, and the ECM-rich rigid structure within these tumors is thought to be a cause of abnormal bleeding and pelvic pain. Therefore, a better understanding of ECM accumulation and remodeling is critical for developing new therapeutics for uterine leiomyoma. SEARCH METHODS: PubMed and Google Scholar were searched for all original and review articles/book chapters related to ECM and medical treatments of uterine leiomyoma published in English until May 2017. OUTCOMES: This review discusses the involvement of ECM in leiomyoma pathogenesis as well as current and future medical treatments that target ECM directly or indirectly. Uterine leiomyoma is characterized by elevated levels of collagens, fibronectin, laminins and proteoglycans. They can induce the mechanotransduction process, such as activation of the integrin-Rho/p38 MAPK/ERK pathway, resulting in cellular responses that are involved in pathogenesis and altered bidirectional signaling between leiomyoma cells and the ECM. ECM accumulation is affected by growth factors (TGF-beta, activin-A and PDGF), cytokines (TNF-alpha), steroid hormones (estrogen and progesterone) and microRNAs (miR-29 family, miR-200c and miR-93/106b). Among these, TGF-betas (1 and 3) and activin-A have been suggested as key players in the accumulation of excessive ECM (fibrosis) in leiomyoma. The presence of elevated levels of ECM and myofibroblasts in leiomyoma supports the fibrotic character of these tumors. Interestingly, ECM may serve as a reservoir of profibrotic growth factors and enhance their activity by increasing their stability and extending their duration of signaling. At present, several classes of compounds, including gonadotropin-releasing hormone (GnRH) agonist (leuprolide acetate), GnRH antagonist (cetrorelix acetate), selective progesterone receptor modulators (ulipristate acetate and asoprisnil), antiprogestin (mifepristone) and natural compounds like vitamin D and resveratrol have been studied as medical treatments that target ECM in uterine leiomyoma. WIDER IMPLICATIONS: Although several types of drugs (mostly antiproliferative agents) are available for leiomyoma treatment, none of them were introduced specifically as antifibrotic agents. In light of its critical role in the process of fibrosis in leiomyoma, we propose that ECM should be considered as a crucial target for future therapeutics. Thus, the introduction of drugs that are specifically antifibrotic could be a good solution to control abnormal leiomyoma growth and associated clinical symptoms. The antifibrotic compounds can be introduced based on their ability to regulate ECM components and their receptors, as well as growth factors, cytokines, steroid hormones and their corresponding receptors and intracellular signaling pathways, as well as microRNAs, involved in ECM production in leiomyoma. PMID- 29186430 TI - The effects of fungal root endophytes on plant growth are stable along gradients of abiotic habitat conditions. AB - Plant symbioses with fungal root endophytes span a continuum from mutualistic to parasitic outcomes, and are highly variable depending on the genotype of each symbiont. The abiotic context in which interactions occur also seems to influence the outcome of plant-endophyte symbioses, but we lack understanding of its relative importance. We aimed to assess if changes in abiotic variables determine the effects of fungal root endophytes on plant growth. We used in vitro co cultivation assays to test the impact of a selection of endophytic strains from diverse lineages on the growth of Arabidopsis thaliana, Microthlaspi erraticum and Hordeum vulgare along gradients of nutrient availability, light intensity or substrate pH. Most fungi showed a negative but weak effect on plant growth, whereas only a few had persistent detrimental effects across plants and conditions. Changes in abiotic factors affected plant growth but had little influence on their response to fungal inoculation. Of the factors tested, variation in nutrient availability resulted in the most variable plant-endophyte interactions, although changes were feeble and strain-specific. Our findings suggest that the effects of root endophytes on plant growth are robust to changes in the abiotic environment when these encompass the tolerance range of either symbiont. PMID- 29186432 TI - Bacterial zincophore [S,S]-ethylenediamine-N,N'-disuccinic acid is an effective inhibitor of MBLs. AB - Objectives: Carbapenemases such as MBLs are spreading among Gram-negative bacterial pathogens. Infections due to these MDR bacteria constitute a major global health challenge. Therapeutic strategies against carbapenemase-producing bacteria include beta-lactamase inhibitor combinations. [S,S]-ethylenediamine N,N'-disuccinic acid (EDDS) is a chelator and potential inhibitor of MBLs. We investigated the activity of EDDS in combination with imipenem against MBL producing bacteria in vitro as well as in vivo. Methods: The inhibitory activity of EDDS was analysed by means of a fluorescence-based assay using purified recombinant MBLs, i.e. NDM-1, VIM-1, SIM-1 and IMP-1. The in vitro activity of imipenem +/- EDDS against mutants as well as clinical isolates expressing MBLs was evaluated by broth microdilution assay. The in vivo activity of imipenem +/- EDDS was analysed in a Galleria mellonella infection model. Results: EDDS revealed potent MBL inhibitory activity against purified NDM-1, weaker activity against VIM-1 and SIM-1, and marginal activity against IMP-1. EDDS did not exhibit any intrinsic antibacterial activity, but enabled a concentration dependent potentiation of imipenem against mutants as well as clinical isolates expressing various MBLs. The in vivo model showed a significantly better survival rate for imipenem + EDDS-treated G. mellonella larvae infected with NDM-1 producing Klebsiella pneumoniae compared with monotherapy with imipenem. Conclusions: The bacterial natural zincophore EDDS is a potent MBL inhibitor and in combination with imipenem overcomes MBL-mediated carbapenem resistance in vitro and in vivo.

AB - Striacosta albicosta (Smith; Lepidoptera: Noctuidae) is a pest of corn (Zea mays L.), which has recently expanded its range into Ontario, Canada. Genetically modified corn expressing Vip3A insecticidal protein from Bacillus thuringiensis is a biotechnological option for the control of S. albicosta. To support an insect resistance management program, we conducted a study of baseline susceptibility of 10-field collected S. albicosta populations in Ontario, Canada to Vip3A before widespread commercial adoption. Neonates were exposed to artificial diet overlaid with Vip3A. The LC50 ranged from 22.7 to 53.5 ng Vip3A cm-2. The EC50 ranged from 11.4 to 30.2 ng Vip3A cm-2. There was low inter population variation in susceptibility to Vip3A, which we believe represents the natural geographical variation in response and not variation caused by previous exposure to selection pressure of the Vip3A protein. PMID- 29186431 TI - Monoamine Oxidase A Gene Methylation and Its Role in Posttraumatic Stress Disorder: First Evidence from the South Eastern Europe (SEE)-PTSD Study. AB - Background: Posttraumatic stress disorder is characterized by an overactive noradrenergic system conferring core posttraumatic stress disorder symptoms such as hyperarousal and reexperiencing. Monoamine oxidase A is one of the key enzymes mediating the turnover of noradrenaline. Here, DNA methylation of the monoamine oxidase A gene exonI/intronI region was investigated for the first time regarding its role in posttraumatic stress disorder risk and severity. Methods: Monoamine oxidase A methylation was analyzed via direct sequencing of sodium bisulfite treated DNA extracted from blood cells in a total sample of N=652 (441 male) patients with current posttraumatic stress disorder, patients with remitted posttraumatic stress disorder, and healthy probands (comparison group) recruited at 5 centers in Bosnia-Herzegovina, Croatia, and the Republic of Kosovo. Posttraumatic stress disorder severity was measured by means of the Clinician Administered Posttraumatic Stress Disorder Scale and its respective subscores representing distinct symptom clusters. Results: In the male, but not the female sample, patients with current posttraumatic stress disorder displayed hypermethylation of 3 CpGs (CpG3=43656362; CpG12=43656514; CpG13=43656553, GRCh38.p2 Assembly) as compared with remitted Posttraumatic Stress Disorder patients and healthy probands. Symptom severity (Clinician-Administered Posttraumatic Stress Disorder Scale scores) in male patients with current posttraumatic stress disorder significantly correlated with monoamine oxidase A methylation. This applied particularly to symptom clusters related to reexperiencing of trauma (cluster B) and hyperarousal (cluster D). Conclusions: The present findings suggest monoamine oxidase A gene hypermethylation, potentially resulting in enhanced noradrenergic signalling, as a disease status and severity marker of current posttraumatic stress disorder in males. If replicated, monoamine oxidase A hypermethylation might serve as a surrogate marker of a hyperadrenergic subtype of posttraumatic stress disorder guiding personalized treatment decisions on the use of antiadrenergic agents. PMID- 29186434 TI - Rapid disc diffusion antibiotic susceptibility testing for Pseudomonas aeruginosa, Acinetobacter baumannii and Enterococcus spp. AB - Background: We investigated the feasibility of rapid disc diffusion antibiotic susceptibility testing (rAST) with reading of inhibition zones after 6 and/or 8 h of incubation for Enterococcus faecalis, Enterococcus faecium, Pseudomonas aeruginosa and Acinetobacter baumannii. In addition, we evaluated discrimination of resistant populations from the WT populations at early timepoints and the requirement for clinical breakpoint adaptations for proper interpretation of rAST data. Methods: In total, 815 clinical strains [E. faecalis (n = 135), E. faecium (n = 227), P. aeruginosa (n = 295) and A. baumannii (n = 158)] were included in this study. Disc diffusion plates were streaked, incubated and imaged using the WASPLabTM automation system. WT populations and non-WT populations were defined using epidemiological cut-offs. Results and conclusions: rAST at 6 and 8 h was possible for A. baumannii and enterococci with readability of inhibition zones >90%. Overall categorical agreement of rAST at 6 h with AST at 18 h was 97.2%, 97.4% and 95.3% for E. faecalis, E. faecium and A. baumannii, respectively. With few exceptions, major categorization error rates were <1% for A. baumannii, and vancomycin-resistant E. faecium were clearly separated from the WT at 6 h. For P. aeruginosa the average readability of inhibition zones was 68.9% at 8 h and we found an overall categorical agreement of 94.8%. Adaptations of clinical breakpoints and/or introduction of technical buffer zones, preferably based on aggregated population data from various epidemiological settings, are required for proper interpretation of rAST. PMID- 29186435 TI - Vermicomposts of Different Origins Protect Tomato Plants Against the Sweetpotato Whitefly. AB - The effect of four vermicomposts, obtained from different organic sources (pistachio waste [PWV], date waste [DWV], cattle manure waste [CMV], and food waste [FWV]), as well as two chemical fertilizers (complete fertilizer [CF] and NPK fertilizer [NPK]) on some life history traits of the sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) was investigated in a series of choice and not choice experiments. In a choice experiment, adult whiteflies exhibited significantly lower preference for settling and oviposition on plants treated with vermicomposts than those in control, CF, and NPK groups (P < 0.01), with better results were observed in PWV group. In no choice experiment, adult whiteflies laid significantly fewer eggs in PWV group in comparison with control, CF, and NPK groups (P < 0.01); other treatments had intermediary values. Fertilization had a significant effect on the preadult development time of sweetpotato whitefly, with the longest development times were recorded for plants treated with PWV (24.65 d) and FWV (22.04 d), respectively. The preadult mortality of sweetpotato whitefly increased significantly following fertilization, with the greatest mortal effects were observed in PWV (54.11%) and DWV (44.68%) groups, respectively. Plants fertilized with PWV had significantly higher phenolic content (10 mg/ml) than control (BAGA; 6.08 mg/ml), while those in CMV group exhibited intermediary value (7.28 mg/ml). Altogether, results of this study reveal both antixenosis (nonpreference) and antibiosis (decreased survival and prolonged development time) resistance of tomato plants mediated by vermicomposts. Particularly, plants treated with PWV obtained the best results in terms of both growth and resistance to sweetpotato whitefly. PMID- 29186437 TI - Dr Jeremy Fauconnier talks with Prof Goran K. Hansson. PMID- 29186436 TI - Transcriptome profiling of fetal Klinefelter testis tissue reveals a possible involvement of long non-coding RNAs in gonocyte maturation. AB - In humans, the most common sex chromosomal disorder is Klinefelter syndrome (KS), caused by the presence of one or more extra X-chromosomes. KS patients display a varying adult phenotype but usually present with azoospermia due to testicular degeneration, which accelerates at puberty. The timing of the germ cell loss and whether it is caused by dysgenetic fetal development of the testes is not known. We investigated eight fetal KS testes and found a marked reduction in MAGE-A4 positive pre-spermatogonia compared with testes from 15 age-matched controls, indicating a failure of the gonocytes to differentiate into pre-spermatogonia. Transcriptome analysis by RNA-sequencing of formalin-fixed, paraffin-embedded testes originating from four fetal KS and five age-matched controls revealed 211 differentially expressed transcripts in the fetal KS testis. We found a significant enrichment of upregulated X-chromosomal transcripts and validated the expression of the pseudoautosomal region 1 (PAR1) gene, AKAP17A. Moreover, we found enrichment of long non-coding RNAs in the KS testes (e.g. LINC01569 and RP11-485F13.1). In conclusion, our data indicate that the testicular phenotype observed among adult men with KS is initiated already in fetal life by failure of the gonocyte differentiation into pre-spermatogonia, which could be due to aberrant expression of long non-coding RNAs.

PMID- 29186442 TI - Additional diagnostic value of CMR to the European Society of Cardiology (ESC) position statement criteria in a large clinical population of patients with suspected myocarditis. AB - Aims: To determine the diagnostic yield of tissue characterization by cardiovascular magnetic resonance (CMR) in a large clinical population of patients with suspected acute myocarditis (AM) and to establish its diagnostic value within the 2013 European Society of Cardiology position statement criteria (ESC-PSC) for clinically suspected myocarditis. Methods and results: In this retrospective study, CMR examinations of 303 hospitalized patients referred for work-up of suspected AM in two tertiary referral centres were analysed. CMR was performed at median 7 days (interquartile range 4-20 days) after clinical presentation and included cine imaging, T2-weighted imaging, and late gadolinium enhancement. CMR images were evaluated to assign each patient to a diagnosis. By using non-CMR criteria only, the 2013 ESC-PSC were positive for suspected myocarditis in 151 patients and negative in 30. In the remaining 122 patients, there was insufficient information available for ESC-PSC assessment, mostly due to lack of coronary angiography (CAG) before the CMR examination (n = 116, 95%). There were no in-hospital deaths. CMR provided a diagnosis in 158 patients (52%), including myocarditis in 104 (34%), myocardial infarction in 44 (15%), and other pathology in 10 patients (3%). Non-urgent CAG (>24 h after presentation) was performed before the CMR examination in 85 patients, of which 20 (24%) were done in patients with subsequently confirmed AM, which could potentially have been avoided if CMR was performed first. ESC-PSC was correct in diagnosing AM before the CMR in 50 of the 151 patients (33%) and was correct in ruling out AM in all the 30 patients (100%). However, ESC-PSC provided an incorrect diagnosis of AM in 27 of the 151 patients (18%), which was corrected by CMR through the identification of new cardiac disease that could explain the clinical syndrome. Patients with insufficient ESC-PSC information had a relatively low pre-test probability of coronary artery disease. In this group, CMR confirmed the diagnosis of AM in a relatively high percentage (44%) but still revealed myocardial infarction in 8% of them. Conclusion: Tissue characterization by CMR provided a good diagnostic yield in this large clinical population of patients with suspected AM. CMR provided incremental diagnostic value to the ESC-PSC by ruling out the diagnosis of AM on one hand and by potentially sparing AM patients from CAG on the other.

AB - Heparan sulfate (HS) is a polysaccharide fundamentally important for biologically activities. T/Tn antigens are universal carbohydrate cancer markers. Here, we report the specific imaging of these carbohydrates using a mesenchymal stem cell line and human umbilical vein endothelial cells (HUVEC). The staining specificities were demonstrated by comparing imaging of different glycans and validated by either removal of target glycans, which results in loss of signal, or installation of target glycans, which results in gain of signal. As controls, representative key glycans including O-GlcNAc, lactosaminyl glycans and hyaluronan were also imaged. HS staining revealed novel architectural features of the extracellular matrix (ECM) of HUVEC cells. Results from T/Tn antigen staining suggest that O-GalNAcylation is a rate-limiting step for O-glycan synthesis. Overall, these highly specific approaches for HS and T/Tn antigen imaging should greatly facilitate the detection and functional characterization of these biologically important glycans.

AB - : The risks associated with soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), in the North Central soybean systems has fostered the adoption of prophylactic chemical control practices, such as planting seeds treated with neonicotinoid insecticides, especially thiamethoxam. Consequently, there is a concern that increased selection pressure imposed on the arthropod-pest complex by this insecticide may lead to resistance. Therefore, in vivo bioassays were conducted to determine the susceptibility of soybean aphid to thiamethoxam among North Central U.S. POPULATIONS: Concentration-mortality data were collected using contact glass-vial and detached-leaf systemic bioassays. The results of these experiments indicate that both bioassays were reliable to detect shifts in susceptibility between different soybean aphid clones. The LC50s of field populations of soybean aphid were significantly different when mortality was recorded in contact and systemic exposure assays. Nevertheless, the magnitude of the resistance ratios was consistent in both methods. In addition, a significant increase in the LC50 and EC50 values was observed among field populations tested in detached-leaf systemic bioassays. These results represent the first extensive efforts to identify the variability in susceptibility of soybean aphid to thiamethoxam in the North Central United States Therefore, our results provide a baseline for future assessment and contribute to a better understanding of the applicability of in vivo bioassays for susceptibility monitoring and resistance detection of soybean aphid to thiamethoxam. PMID- 29186446 TI - Validation of the i-STAT(r)1 Analyzer for Postmortem Vitreous Humor Electrolytes and Glucose Analysis. AB - The analytical value of vitreous humor as a specimen in postmortem forensic toxicology has been known for some time. Numerous medical examiner laboratories outsource the analysis of this important specimen for electrolyte and glucose measurements. This can be both time-consuming and costly. The utility of the i STAT(r)1 medical device to measure electrolytes and glucose in whole blood samples has been demonstrated for over two decades in a clinical setting through single-use disposable cartridges that introduce samples to the i-STAT(r)1. Different cartridge types allow for the analysis of various analytes including sodium, potassium, chloride, creatinine, urea nitrogen and glucose. With only 100 MUL of sample, results are obtained in under 4 min. In this study, we utilized the i-STAT(r)1 using an alternative specimen matrix, postmortem vitreous humor and quantitatively determined the validity and reliability of the instrument for this purpose. Acceptable criterion was used for each test as suggested by the Scientific Working Group for Forensic Toxicology. All analytes of interest, except creatinine, demonstrated a percent error < +/-10% for both accuracy and precision studies. Drug interference and stability studies were performed with many of the analytes demonstrating a percent error < +/-20%. Throughout drug interference and stability studies, all analytes of interest were detectable except for potassium, which gave inconclusive results. Significant interference with commonly found drugs were shown for creatinine and chloride but must be evaluated carefully. Volume additions to ethanol spiked samples caused significant interference for all analytes and is considered a limitation for this method of analysis that requires additional studies. As vitreous humor continues to be used in forensic medicine to aid in diagnostic interpretation, the i STAT(r)1 has the potential to give accurate results in a timely and cost effective manner. PMID- 29186447 TI - Large-scale phylogenomic analysis resolves a backbone phylogeny in ferns. AB - Background: Ferns, originated about 360 million years ago, are the sister group of seed plants. Despite the remarkable progress in our understanding of fern phylogeny, with conflicting molecular evidence and different morphological interpretations, relationships among major fern lineages remain controversial. Results: With the aim to obtain a robust fern phylogeny, we carried out a large scale phylogenomic analysis using high-quality transcriptome sequencing data, which covered 69 fern species from 38 families and 11 orders. Both coalescent based and concatenation-based methods were applied to both nucleotide and amino acid sequences in species tree estimation. The resulting topologies are largely congruent with each other, except for the placement of Angiopteris fokiensis, Cheiropleuria bicuspis, Diplaziopsis brunoniana, Matteuccia struthiopteris, Elaphoglossum mcclurei, and Tectaria subpedata. Conclusions: Our result confirmed that Equisetales is sister to the rest of ferns, and Dennstaedtiaceae is sister to eupolypods. Moreover, our result strongly supported some relationships different from the current view of fern phylogeny, including that Marattiaceae may be sister to the monophyletic clade of Psilotaceae and Ophioglossaceae; that Gleicheniaceae and Hymenophyllaceae form a monophyletic clade sister to Dipteridaceae; and that Aspleniaceae is sister to the rest of the groups in eupolypods II. These results were interpreted with morphological traits, especially sporangia characters, and a new evolutionary route of sporangial annulus in ferns was suggested. This backbone phylogeny in ferns sets a foundation for further studies in biology and evolution in ferns, and therefore in plants.

AB - A cross-sectional study was conducted of 500 human immunodeficiency virus (HIV) infected adults frequency matched on age, sex, and community to 500 HIV uninfected individuals in the Rakai District, Uganda to evaluate seroprevalence of anti-hepatitis E virus (HEV) IgG antibodies. HEV seroprevalence was 47%, and 1 HIV-infected individual was actively infected with a genotype 3 virus. Using modified Poisson regression, male sex (prevalence ratios [PR] = 1.247; 95% confidence interval [CI], 1.071-1.450) and chronic hepatitis B virus infection (PR = 1.377; 95% CI, 1.090-1.738) were associated with HEV seroprevalence. HIV infection status (PR = 0.973; 95% CI, 0.852-1.111) was not associated with HEV seroprevalence. These data suggest there is a large burden of prior exposure to HEV in rural Uganda.

AB - Summary: Split-networks are a generalization of phylogenetic trees that have proven to be a powerful tool in phylogenetics. Various ways have been developed for computing such networks, including split-decomposition, NeighborNet, QNet and FlatNJ. Some of these approaches are implemented in the user-friendly SplitsTree software package. However, to give the user the option to adjust and extend these approaches and to facilitate their integration into analysis pipelines, there is a need for robust, open-source implementations of associated data structures and algorithms. Here, we present SPECTRE, a readily available, open-source library of data structures written in Java, that comes complete with new implementations of several pre-published algorithms and a basic interactive graphical interface for visualizing planar split networks. SPECTRE also supports the use of longer running algorithms by providing command line interfaces, which can be executed on servers or in High Performance Computing environments.

PMID- 29186449 TI - The Thyroid Hormone Inactivating Type 3 Deiodinase Is Essential for Optimal Neutrophil Function: Observations From Three Species. AB - Neutrophils are essential effector cells of the innate immune system that have recently been recognized as thyroid hormone (TH) target cells. Cellular TH bioavailability is regulated by the deiodinase enzymes, which can activate or inactivate TH. We have previously shown that the TH inactivating enzyme type 3 deiodinase (D3) is present in neutrophils. Furthermore, D3 knockout (D3KO) mice show impaired bacterial killing upon infection. We hypothesized that D3 plays a role in neutrophil function during infection by actively regulating local TH availability. We measured TH concentrations in cerebrospinal fluid (CSF) from patients with bacterial meningitis and controls. Bacterial meningitis resulted in marked changes in CSF TH levels, characterized by a strong increase of thyroxine and reverse-triiodothyronine concentrations. This altered TH profile was consistent with elevated D3 activity in infiltrating neutrophils at the site of infection. D3 knockdown in zebrafish embryos with pneumococcal meningitis resulted in increased mortality and reduced neutrophil infiltration during infection. Finally, stimulated neutrophils from female D3KO mice exhibited impaired NADPH-oxidase activity, an important component of the neutrophil bacterial killing machinery. These consistent findings across experimental models strongly support a critical role for reduced intracellular TH concentrations in neutrophil function during infection, for which the TH inactivating enzyme D3 appears essential.

AB - In this study, caged calcium alginate-caged multiwalled carbon nanotubes dispersive microsolid phase extraction was described for the first time for the extraction of polycyclic aromatic hydrocarbons (PAHs) from water samples prior to gas chromatographic analysis. Fluorene, phenanthrene and fluoranthene were selected as model compounds. The caged calcium alginate-caged multiwalled carbon nanotubes was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and thermal gravimetry analyses. The effective parameters namely desorption solvent, solvent volume, extraction time, desorption time, the mass of adsorbent and sample volume were optimized. Under the optimum extraction conditions, the developed method showed good linearity in the range of 0.5-50 ng mL-1 (R2 >= 0.996), low limits of detection and quantification (0.42-0.22 ng mL 1) (0.73-1.38 ng mL-1) respectively, good relative recoveries (71.2-104.2%) and reproducibility (RSD 1.8-12.4%, n = 3) for the studied PAHs in water sample. With high enrichment factor (1,000), short extraction time (<30 min), low amounts of adsorbent (100 mg) and low amounts of solvent (0.1 mol) have proven that the microsolid phase extraction method based on calcium alginate-caged multiwalled carbon nanotubes are environmentally friendly and convenient extraction method to use as an alternative adsorbent in the simultaneous preconcentration of PAHs from environmental water samples.

AB - Cardiovascular disease (CVD) is the primary cause of death among men and women worldwide. Nevertheless, our comprehension of how CVD progresses in women and elicits clinical outcomes is lacking, leading CVD to be under-diagnosed and under treated in women. A clear example of this differential presentation of CVD pathophysiologies in females is the strikingly higher prevalence of heart failure with preserved ejection fraction (HFpEF). Women with a history of pre-eclampsia or those who present with co-morbidities such as obesity, hypertension, and diabetes mellitus are at increased risk of developing HFpEF. Long understood to be a critical CVD risk factor, our understanding of how gender differentially affects the development of CVD has been greatly expanded by extensive genomic and transcriptomic studies. These studies uncovered a pivotal role for differential microRNA (miRNA) expression in response to systemic inflammation, where their co ordinated expression forms a post-transcriptional regulatory network that instigates microcirculation defects. Importantly, the potential sex-biased expression of the given miRNAs may explain sex-specific cardiovascular pathophysiologies in women, such as HFpEF. Sex-biased miRNAs are regulated by oestrogen (E2) in their transcription and processing or are expressed from loci on the X-chromosome due to incomplete X-chromosome inactivation. Interestingly, while E2-induced miRNAs predominantly appear to serve protective functions, it could be argued that many X-linked miRNAs have been found to challenge microvascular and myocardial integrity. Therefore, menopausal E2 deficiency, resulting in protective miRNA loss, and the augmentation of X-linked miRNA expression, may well contribute to the molecular mechanisms that underlie the female-specific cardiovascular aetiology in HFpEF.

AB - Current hair testing methods that rely solely on quantification of parent drug compounds are unable to definitively distinguish between drug use and external contamination. One possible solution to this problem is to confirm the presence of unique drug metabolites that cannot be present through contamination, such as phase II glucuronide conjugates. This work demonstrates for the first time that codeine-6-glucuronide, hydromorphone-3-glucuronide, oxymorphone-3-glucuronide, morphine-3-glucuronide and morphine-6-glucuronide are present at sufficient concentrations to be quantifiable in hair of opioid users and that their concentrations generally increase as the concentrations of the corresponding parent compounds increase. Here, we present a validated liquid chromatography tandem mass spectrometry method to quantify codeine-6-glucuronide, dihydrocodeine 6-glucuronide, hydromorphone-3-glucuronide, morphine-3-glucuronide, morphine-6 glucuronide, oxymorphone-3-glucuronide, codeine, dihydrocodeine, dihydromorphine, hydrocodone, hydromorphone, morphine, oxycodone, oxymorphone and 6-acetylmorphine in human hair. The method was used to analyze 46 human hair samples from known drug users that were confirmed positive for opioids by an independent laboratory. Glucuronide concentrations in samples positive for parent analytes ranged from ~1 to 25 pg/mg, and most samples had glucuronide concentrations in the range of ~1 to 5 pg/mg. Relative to the parent concentrations, the average concentrations of the four detected glucuronides were as follows: codeine-6-glucuronide, 2.33%; hydromorphone-3-glucuronide, 0.94%; oxymorphone-3-glucuronide, 0.77%; morphine 3 glucuronide, 0.59%; and morphine-6-glucuronide, 0.93%. PMID- 29186454 TI - External applicability of the COMPASS trial: an analysis of the reduction of atherothrombosis for continued health (REACH) registry. AB - Aims: The aims of the present study were to describe the proportion of patients eligible for the COMPASS trial within the Reduction of Atherothrombosis for Continued Health (REACH) registry, the reasons for ineligibility, and to put in perspective the characteristics and outcomes of trial-eligible patients from the REACH registry compared with those of patients enrolled in the reference aspirin arm of the COMPASS trial. Methods and results: The COMPASS selection and exclusion criteria were applied to REACH patients with either coronary artery disease (CAD) or peripheral artery disease (PAD). We used the COMPASS primary composite outcome of cardiovascular (CV) death, myocardial infarction (MI), or stroke. In REACH, 31 873 patients had CAD or PAD and detailed information allowing evaluation of eligibility. Among these, 9518 (29.9%) patients had exclusion criteria and an additional 5480 patients (17.2%) did not fulfil the inclusion criteria and thus were not eligible. The 'COMPASS-Eligible' population therefore comprised 52.9% of the evaluable REACH patients (n = 16 875). The main reasons for exclusion were high-bleeding risk (51.8%), anticoagulant use (44.8%), requirement for dual antiplatelet therapy within 1 year of an ACS or PCI with stent, (25.9%), history of ischaemic stroke <1 year (12.4%), and severe renal failure (2.2%). Eligibility was highest among patients with PAD alone (68.4%). COMPASS-Eligible patients from REACH experienced higher annualized primary outcome event rates than patients actually enrolled in the reference aspirin arm of COMPASS (4.2% vs. 2.9% per year, P < 0.001). Conclusion: COMPASS-Eligible patients represent a substantial fraction of stable CAD/PAD patients encountered in routine clinical practice in the large international REACH registry suggesting good external applicability. COMPASS-Eligible patients experienced a higher rate of the primary outcome compared with COMPASS participants in the aspirin alone treatment arm. PMID- 29186455 TI - Recommendations for Toxicological Investigation of Drug-Impaired Driving and Motor Vehicle Fatalities-2017 Update. AB - This report describes the outcomes of a process undertaken to review and update the National Safety Council's Alcohol, Drugs and Impairment Division's recommendations for the toxicological investigation of suspected alcohol and drug impaired driving cases and motor vehicle fatalities. The updates to the recommendations are made based on a survey of practices in laboratories in the USA and Canada performing testing in these cases, consideration of existing epidemiological crash and arrest data, current drug use patterns, and practical considerations of widely available technology platforms in laboratories performing this work. The final recommendations updates are derived from a consensus meeting of experts recruited from survey respondents and the membership of the National Safety Council's Alcohol, Drug and Impairment Division. The principal changes in this round of recommendations include removal of butalbital, phenobarbital, and phencyclidine from Tier I (mandatory) to Tier II (optional) due to changes in prevalence. In addition, buprenorphine, fentanyl, tramadol, and their metabolites were moved from Tier II to Tier I due to increased prevalence and concerns about their potential for causing impairment. In addition, screening and confirmatory cutoffs for the oral fluid scope were further refined. Other additions were made to the list of Tier II compounds including fentanyl analogs (e.g., acetylfentanyl, butyrylfentanyl, furanylfentanyl, etc), mitragynine, novel opioids (e.g., MT-45, U-47700), atypical antipsychotics, and novel benzodiazepines (e.g., clonazolam, flubromazolam, etc). PMID- 29186456 TI - The Anti-Human Immunodeficiency Virus Drug Tenofovir, a Reverse Transcriptase Inhibitor, Also Targets the Herpes Simplex Virus DNA Polymerase. AB - Background: Genital herpes is an important cofactor for acquisition of human immunodeficiency virus (HIV) infection, and effective prophylaxis is a helpful strategy to halt both HIV and herpes simplex virus (HSV) transmission. The antiretroviral agent tenofovir, formulated as a vaginal microbicide gel, was shown to reduce the risk of HIV and HSV type 2 (HSV-2) acquisition. Methods: HSV type 1 (HSV-1) and HSV-2 mutants were selected for resistance to tenofovir and PMEO-DAPy (6-phosphonylmethoxyethoxy-2,4-diaminopyrimidine, an acyclic nucleoside phosphonate with dual anti-HSV and anti-HIV activity) by stepwise dose escalation. Several plaque-purified viruses were characterized phenotypically (drug resistance profiling) and genotypically (sequencing of the viral DNA polymerase gene). Results: Tenofovir resistant and PMEO-DAPy-resistant viruses harbored specific amino acid substitutions associated with resistance not only to tenofovir and PMEO-DAPy but also to acyclovir and foscarnet. These amino acid changes (A719V, S724N, and L802F [HSV-1] and M789T and A724V [HSV-2]) were also found in clinical isolates recovered from patients refractory to acyclovir and/or foscarnet therapy or in laboratory-derived strains. A total of 10 (HSV-1) and 18 (HSV-2) well-characterized DNA polymerase mutants had decreased susceptibility to tenofovir and PMEO-DAPy. Conclusions: Tenofovir and PMEO-DAPy target the HSV DNA polymerase, and clinical isolates with DNA polymerase mutations emerging under acyclovir and/or foscarnet therapy showed cross-resistance to tenofovir and PMEO DAPy. PMID- 29186457 TI - Reproductive Hormone Levels Predict Changes in Frailty Status in Community Dwelling Older Men: European Male Ageing Study Prospective Data. AB - Context: Clinical sequelae of androgen deficiency share common features with frailty. Evidence supporting the role of androgens in the development of frailty is limited and conflicting. Objective: To determine associations between male reproductive hormones and prospective changes in frailty status. Design/Setting: A 4.3-year prospective cohort study of community-dwelling men participating in the European Male Ageing Study. Participants: A total of 3369 men aged 40 to 79 from eight European centers. Intervention: None. Main Outcome Measure: Frailty status was determined using frailty index (FI; n = 2278) and frailty phenotype (FP; n = 1980). Results: After adjusting for baseline frailty, age, center, and smoking, the risk of worsening FI decreased with higher testosterone (T), free T, and dihydrotestosterone (DHT) [percentage change (95% confidence interval) in FI associated with 1 standard deviation higher hormone level: -3.0 (-5.9, -1.0) for total T; -3.9 (-6.8, -2.0) for free T; and -3.9 (-6.8, -2.0) for DHT]. After further adjustment for body mass index, only free T remained a significant predictor of FI change. In fully adjusted models, higher luteinizing hormone and follicle-stimulating hormone were positively related to worsening FI only in men <60 years, and higher estradiol predicted lower likelihood of improving FP [odds ratio: 0.68 (0.52, 0.88)]. Conclusions: These prospective data support the hypothesis that higher androgen levels may protect elderly men from worsening frailty. However, the causal nature of these relationships requires further investigation. Whereas raised gonadotropins in men <60 years might be an early marker of frailty, the role of estradiol in frailty needs further clarification. PMID- 29186458 TI - Four-days-a-week antiretroviral maintenance therapy in virologically controlled HIV-1-infected adults: the ANRS 162-4D trial. AB - Background: Intermittent treatment could improve the convenience, tolerability and cost of ART, as well as patients' quality of life. We conducted a 48 week multicentre study of a 4-days-a-week antiretroviral regimen in adults with controlled HIV-1-RNA plasma viral load (VL). Methods: Eligible patients were adults with VL < 50 copies/mL for at least 1 year on triple therapy with a ritonavir-boosted PI (PI/r) or an NNRTI. The study protocol consisted of the same regimen taken on four consecutive days per week followed by a 3 day drug interruption. The primary outcome was the proportion of participants remaining in the strategy with VL < 50 copies/mL up to week 48. The study was designed to show an observed success rate of > 90%, with a power of 87% and a 5% type 1 error. The study was registered with ClinicalTrials.gov (NCT02157311) and EudraCT (2014 000146-29). Results: One hundred patients (82 men), median age 47 years (IQR 40 53), were included. They had been receiving ART for a median of 5.1 (IQR 2.9-9.3) years and had a median CD4 cell count of 665 (IQR 543-829) cells/mm3. The ongoing regimen included PI/r in 29 cases and NNRTI in 71 cases. At 48 weeks, 96% of participants (95% CI 90%-98%) had no failure while remaining on the 4-days-a-week regimen. Virological failure occurred in three participants, who all resumed daily treatment and became resuppressed. One participant stopped the strategy. No severe treatment-related events occurred. Conclusions: Antiretroviral maintenance therapy 4 days a week was effective for 48 weeks in 96% of patients, leading to potential reduction of long-term toxicities, high adherence to the antiretroviral regimen and drug cost saving. PMID- 29186459 TI - The long-term impact of a change in Effort-Reward imbalance on mental health results from the prospective MAN-GO study. AB - Background: Little is yet known on the long-term effects of stress management interventions (SMIs) in the workplace. The aim this study was to prospectively examine the effect of an improvement of psychosocial working conditions measured by the Effort-Reward (E-R) Imbalance model within 2 years following an SMI, and mental health 7 years later. Methods: The study sample consisted of 97 male industrial workers from southern Germany. Data were collected pre- and post intervention in 2006 (T1) and 2008 (T2), respectively, as well as in 2015 (T3). Change scores were computed by subtracting T1 from T3 values. The associations between E-R ratio at T1, T2 and the change score, respectively, with depression and anxiety 7 years later were estimated by means of linear regression analysis. Analyses were adjusted for baseline levels of the exposure and outcome variables, socio-demographic-, health- and work-related covariates. Results: Within-person comparisons revealed a significant reduction (i.e. improvement) in E-R ratio post intervention (-0.103, SD 0.24, P = 0.000). This improvement in the E-R ratio was significantly associated with lower anxiety (beta = 0.358, P = 0.001) and depression (beta = 0.246, P = 0.031) scores in the fully adjusted models. The association between change scores and mental health were slightly stronger than associations with absolute values at T1 and T2. Conclusions: An improvement in E R ratio following an SMI, was significantly associated with lower anxiety and depression 7 years later. These results strongly support the importance of improving psychosocial working conditions in order to protect the mental health of employees in the long-run. PMID- 29186461 TI - Advancing the evaluation of cervical cancer screening: development and application of a longitudinal adherence metric. AB - Background: Attendance to routine cancer screening at repeated intervals is essential for reducing morbidity and mortality of targeted cancers, yet currently defined quality-assurance metrics evaluate coverage within a defined period of time (e.g. 3.5 years). Methods: We developed a longitudinal adherence metric that captures attendance to cancer screening at repeated intervals, and applied the metric to population-based data from the Cancer Registry of Norway that captures two decades of organised cervical cancer screening, including all screening tests and cervical cancer diagnoses for women living in Norway at any time during years 1992-2013 and eligible for at least two screening rounds (1 round = 3.5 years, N = 1 391 812). For each woman, we calculated the proportion of eligible screening rounds with at least one registered cytology test, and categorised women into one of five longitudinal adherence categories: never-screeners, severe under screeners, moderate under-screeners, guidelines-based screeners and over screeners. For each category, we evaluated cancer outcomes such as cancer stage at diagnosis. Results: Only 46% of screen-eligible women were consistently screened at least once every 3.5 years, and the majority of these were over screened. In contrast, 29% were moderately under-screened, 17% were severely under-screened and 8% had never attended screening. Screening behaviour was associated with cancer outcomes; e.g., the proportion of cancers diagnosed at Stage I increased from 21% among never-screeners to 70% among over-screeners. Conclusion: The longitudinal adherence metric evaluates screening performance as a succession of screening episodes, reflecting both guidelines and the fundamental principles of screening, and may be a valuable addition to existing performance indicators. PMID- 29186460 TI - Understanding the relation between socioeconomic position and inflammation in post-menopausal women: education, income and occupational prestige. AB - Background: The role of occupational prestige, a direct measure of the perceived status of job and job holder, in inflammation is unknown. To contribute to understanding the pathways by which socioeconomic position (SEP) is associated with inflammation, we aimed to estimate the direct effects of education, income and occupational prestige on C-reactive protein (CRP) and to describe the relationship between these markers and CRP. Methods: The study was based on 2026 post-menopausal women enrolled in the Women's Health Initiative-Observational Study. Occupational prestige was determined by linking a text description of longest held occupation with a social status item from the Occupational Information Network. Path analysis was employed to estimate direct and mediated effects. Results: The study suggests that higher levels of education, income, and occupational prestige are associated with 8% (95% CI as percentage change -12, 4), 5% [95% CI (-8, -2) and 4% (95% CI - 7, -1)] lower levels of CRP, respectively. The inverse association between education and CRP was explained by the effect of education on income and occupational prestige. The effect of occupational prestige on CRP was independent of mediators in the model. Conclusions: The findings indicate that education may work to influence CRP primarily through increasing income and occupational prestige and provides evidence that occupational prestige captures a unique aspect of SEP. PMID- 29186462 TI - Haemorrhagic fever with renal syndrome in Montenegro, 2004-14. AB - From 2004 to 2014, 106 cases of Human haemorrhagic fever with renal syndrome were notified in Montenegro, with a peak in 2014. Most of the cases occurred in summer, in the North-east and Central Montenegro, a hilly/mountainous area, that provides suitable habitats for the main rodent carriers. Cases were mainly males (71) and exposures were often working outdoor or spending time visiting mountains and lakes. Incidence correlated with average annual temperature increase and average annual rainfalls decrease, but not with land cover. Environment and climate effects on HFRS in Montenegro need further investigation to get insight into future trends. PMID- 29186463 TI - Does public reporting influence quality, patient and provider's perspective, market share and disparities? A review. AB - Background: Public reporting (PR) of healthcare (HC) provider's quality was proposed as a public health instrument for providing transparency and accountability in HC. Our aim was to assess the impact of PR on five main domains: quality improvement; patient choice, service utilization and market share; provider's perspective; patient experience; and unintended consequences. Methods: PubMed, Scopus, ISI WOS, and EconLit databases were searched to identify studies investigating relationships between PR and five main domains, published up to April 1, 2016. Results: Sixty-two papers published between 1988 and 2015 were included. Nineteen studies investigated quality improvement, 19 studies explored the unintended consequences of PR, 10 explored the effects on market share, 10 on patients' choice, 7 evaluated the provider's perspective, 4 economic outcome, 4 service utilization, 2 purchasers' use of PR and 2 studies explored patient experiences. The effect of PR was diverse throughout the studies-mostly positive on: patient experience (100%), quality improvement (63%), patient choice, service utilization and market share (46%); mixed on provider's perspective and economic outcome (27%) and mainly negative on unintended consequences (68%). Conclusions: Our research covering different outcomes and settings reported that PR is associated with changes in HC provider's behavior and can influence market share. Unintended consequences are a concern of PR and should be taken into account when allocating HC resources. The experiences collected in this paper could give a snapshot about the impact of PR on a HC user's perception of the providers' quality of care, helping them to make empowered choices. PMID- 29186464 TI - Maternal serum bisphenol A levels and risk of pre-eclampsia: a nested case control study. AB - Background: Although recent studies have indicated the potential adverse effects of maternal bisphenol A (BPA) exposure on pregnancy such as increasing the risk of pre-eclampsia, epidemiological evidence is limited. We aimed to evaluate the relationship between maternal BPA exposure and the risk of pre-eclampsia. Methods: We conducted a nested case-control study among 173 women (74 cases of pre-eclampsia and 99 controls). BPA concentrations were measured using liquid chromatography-mass spectrometry in the maternal serum samples collected during 16-20 gestational weeks. Multivariate logistic models were used to examine the relationship between maternal serum BPA concentrations and the risk of pre eclampsia. Results: BPA was detectable (>0.1 ug/l) in 78.6% of the maternal serum samples at three levels: low (<2.24 ug/l), medium (2.24-4.44 ug/l), and high (>4.44 ug/l). BPA concentrations were significantly higher in the serum samples collected from the pre-eclampsia cases than those from controls (median: 3.40 vs. 1.50 ug/l, P < 0.01). With adjustment for maternal age, primiparous and BMI, the odds of developing pre-eclampsia were significantly elevated in subjects with high serum BPA levels compared with those with low levels (adjusted OR = 16.46, 95%CI = 5.42-49.85) regardless of subcategories of pre-eclampsia including severity and onset time. Among the pre-eclampsia subjects, the maternal serum concentration of BPA was not different between the early- and late-onset subjects (median: 3.09 vs. 3.50 ug/l, P = 0.57), but surprisingly higher in mild pre eclampsia subjects compared with severe pre-eclampsia subjects (median: 5.20 vs. 1.80 ug/l, P < 0.01). Conclusions: These results demonstrated that maternal exposure to high level of BPA could be associated with an increased risk of pre eclampsia. PMID- 29186466 TI - Suppression of Mediterranean Fruit Fly (Diptera: Tephritidae) With Trimedlure and Biolure Dispensers in Coffea arabica (Gentianales: Rubiaceae) in Hawaii. AB - To assess the potential to suppress Mediterranean fruit fly, Ceratitis capitata (Wiedemann; Diptera: Tephritidae), via mass trapping with Trimedlure (TML), we compared fly catch (as catch per trap per time period) provided by either a novel, solid, triple-lure dispenser with TML, methyl eugenol (ME), and raspberry ketone (RK) (TMR) or solid TML plugs, both without insecticides, in addition to Biolure bait stations. Work was done in a coffee plantation that had a dense C. capitata population. Three treatments were compared: 1) TMR or TML (50 traps per ha), 2) Biolure (50 traps per ha), 3) TML (25 per ha) or TMR (25 per ha) + Biolure (25 per ha), and 4) an untreated control. During coffee season, based on C. capitata captures (mean flies per trap per wk) inside plastic McPhail traps, all treatments were significantly different than the control: Biolure (9.57) = TMR (11.28) = Biolure +TMR (13.50) < Control (36.06 flies/trap/wk). During non coffee season, all treatments were significantly different than the control and TML was significantly lower than Biolure (wax matrix bait stations): TML (0.95) < Biolure (1.43) = Biolure +TML (1.77) < Control (2.81 flies/trap/wk). Surprisingly, captures were not lower in plots treated with combinations of Biolure + TMR or TML, compared to individual plots with Biolure or TML or TMR alone. Mass trapping with either TML or TMR dispensers deserves further study as a component of Integrated Pest Management programs for C. capitata in Hawaii and may have global potential for management of C. capitata. PMID- 29186467 TI - Biological functions of sulfoglycolipids and the EMARS method for identification of co-clustered molecules in the membrane microdomains. AB - Two major sulfoglycolipids, sulfatide (SO3-3Gal-ceramide) and seminolipid (SO3 3Gal-alkylacylglycerol) exist in mammals. Sulfatide is abundant in the myelin sheath and seminolipid is unique to the spermatogenic cells. The carbohydrate moiety of sulfatide and seminolipid is identical and synthesized by common enzymes: ceramide galactosyltransferase (CGT) and cerebroside sulfotransferase (CST). We have purified CST homogenously, cloned the CST gene and generated CST knockout mice. CST-null mice completely lack sulfoglycolipids all over the body. Analysis of CST-null mice has revealed that sulfatide is an essential component for the axo-glial junction at the paranode region and regulates terminal differentiation of oligodendrocytes, and that seminolipid is responsible for the formation of a functional lactate transporter assembly to take up the critical energy source for spermatocytes. We have developed a new analytical method termed EMARS to identify co-clustered molecules in the membrane microdomains in order to elucidate the functional molecules that collaborate with sulfoglycolipids. PMID- 29186468 TI - Analysis of Memory B-Cell Responses Reveals Suboptimal Dosing Schedule of a Licensed Vaccine. AB - Current guidance recommends that adolescents receive a 2-dose human papillomavirus (HPV) vaccine, whereas young adults and immunocompromised persons receive 3 doses. We examined secondary responses of vaccine-elicited memory B cells (Bmem) in naive women receiving 3 doses of the quadrivalent HPV vaccine to understand the quality of B-cell memory generated by this highly effective vaccine. Unexpectedly, we observed a lower Bmem response rate and magnitude of Bmem responses to the third dose than to a booster dose administered at month 24. Moreover, high titers of antigen-specific serum antibody at vaccination inversely correlated with Bmem responses. As the purpose of additional doses/boosters is to stimulate Bmem to rapidly boost antibody levels, these results indicate the timing of the third dose is suboptimal and lend support to a 2-dose HPV vaccine for young adults. Our findings also indicate more broadly that multidose vaccine schedules should be rationally determined on the basis of Bmem responses. PMID- 29186469 TI - GDP-L-fucose is required for boundary definition in plants. AB - The CUP-SHAPED COTYLEDON (CUC) transcription factors control plant boundary formation, thus allowing the emergence of novel growth axes. While the developmental roles of the CUC genes in different organs and across species are well characterized, upstream and downstream events that contribute to their function are still poorly understood. To identify new players in this network, we performed a suppressor screen of CUC2g-m4, a line overexpressing CUC2 that has highly serrated leaves. We identified a mutation that simplifies leaf shape and affects MURUS1 (MUR1), which is responsible for GDP-L-fucose production. Using detailed morphometric analysis, we show that GDP-L-fucose has an essential role in leaf shape acquisition by sustaining differential growth at the leaf margins. Accordingly, reduced CUC2 expression levels are observed in mur1 leaves. Furthermore, genetic analyses reveal a conserved role for GDP-L-fucose in different developmental contexts where it contributes to organ separation in the same pathway as CUC2. Taken together, our results reveal that GDP-L-fucose is necessary for proper establishment of boundary domains in various developmental contexts. PMID- 29186470 TI - Determination of Acetaminophen, Dexchlorpheniramine, Caffeine, Cotinine and Salicylic acid in 100 MUL of Whole Blood by UHPLC-MS/MS. AB - A sensitive and robust ultra-high-performance liquid chromatography-tandem mass spectrometry method has been developed and validated for the quantification of acetaminophen, dexchlorpheniramine, caffeine, cotinine and salicylic acid in postmortem blood samples from children younger than 4 years. The sample was prepared by a protein precipitation with ice-cold methanol/acetonitrile mixture (85:15, v/v). The organic phase was evaporated to dryness and the residue was dissolved in the mobile phase. Separation, with gradient elution and an acidic mobile phase, was achieved on an Acquity UPLC(r) HSS T3 column. The compounds were quantified using a multiple reaction-monitoring mode. Two transitions were monitored for each compound and one for the deuterated internal standards. The mass spectrometric detection in the positive ion mode was performed for all the compounds except salicylic acid which was detected in the negative ionization mode. The limits of quantification were as follows: acetaminophen 0.30 mg/L, dexchlorpheniramine 0.0050 mg/L, caffeine 0.099 mg/L, cotinine 0.00035 mg/L and salicylic acid 1.3 mg/L. Between-assay and within-assay precisions were <=15% (biases: -10% to 26%) and <=10%, respectively. Extraction recoveries varied from 93% to 137%. The matrix effects in blood, corrected with deuterated internal standards, were 100% +/- 10% for all compounds except dexchlorpheniramine (111%) and caffeine (138%). PMID- 29186471 TI - Reduced proximal tubular expression of protein endocytic receptors in proteinuria is associated with urinary receptor shedding. AB - Background: Filtered proteins, including albumin, are reabsorbed in the proximal tubule (PT) mediated by megalin, cubilin and the neonatal Fc receptor (FcRn). Proteinuria is an important renal biomarker linked to poor prognosis but expression of these key receptors is not well studied. Methods: Megalin expression was determined at protein and messenger RNA (mRNA) levels in kidneys from proteinuric patients, and the expression of megalin, cubilin and FcRn was examined in the kidneys of mice with protein-overload proteinuria. The presence of receptors in the urine of proteinuric and control mice was also studied. Results: In nephrotic patients, megalin expression is reduced while mRNA is increased. In proteinuric mice megalin, cubilin and the neonatal FcRn protein are all reduced in PTs. Megalin and FcRn mRNA are increased in proteinuric mice, whereas that for cubilin was reduced. In proteinuric mice increased urinary excretion of each of these endocytic receptors was observed. Conclusions: It is concluded that in proteinuria, expression of all the key protein re-absorptive receptors is significantly reduced in the PT in association with increased turnover and urinary shedding. PMID- 29186472 TI - Combination Therapy With Neuraminidase and Polymerase Inhibitors in Nude Mice Infected With Influenza Virus. AB - Background: Treatment of immunocompromised, influenza virus-infected patients with the viral neuraminidase inhibitor oseltamivir often leads to the emergence of drug-resistant variants. Combination therapy with compounds that target different steps in the viral life cycle may improve treatment outcomes and reduce the emergence of drug-resistant variants. Methods: Here, we infected immunocompromised nude mice with an influenza A virus and treated them with neuraminidase (oseltamivir, laninamivir) or viral polymerase (favipiravir) inhibitors, or combinations thereof. Results: Combination therapy for 28 days increased survival times compared with monotherapy, but the animals died after treatment was terminated. Mono- and combination therapies did not consistently reduce lung virus titers. Prolonged viral replication led to the emergence of neuraminidase inhibitor-resistant variants, although viruses remained sensitive to favipiravir. Overall, favipiravir provided greater benefit than neuraminidase inhibitors. Conclusions: Collectively, our data demonstrate that combination therapy in immunocompromised hosts increases survival times, but does not suppress the emergence of neuraminidase inhibitor-resistant variants.

AB - Macaca fascicularis aurea (Burmese long-tailed macaque) is 1 of the 10 subspecies of Macaca fascicularis. Despite having few morphological differences from other subspecies, a recent phylogeographic study showed that M. f. aurea is clearly distinct genetically from Macaca fascicularis fascicularis (common long-tailed macaque) and suggests that M. f. aurea experienced a disparate evolutionary pathway versus other subspecies. To construct a detailed evolutionary history of M. f. aurea and its relationships with other macaque species, we performed phylogenetic analyses and divergence time estimation of whole mitochondrial genomes (2 M. f. aurea, 8 M. f. fascicularis, and 16 animals of 12 macaque species) and 2871 bp of the Y chromosome (1 M. f. aurea, 2 M. f. fascicularis, and 5 animals of 5 macaque species) and haplotype network analysis of 758 bp of the Y chromosome (1 M. f. aurea, 2 M. f. fascicularis, and 21 animals of 19 macaque species). Whereas the Y chromosome of M. f. aurea clustered with those of the fascicularis species group in the phylogenetic and haplotype network analyses, its mtDNA clustered within the clade of the sinica species group. Based on this phylogenetic incongruence and the estimated divergence times, we propose that proto-M. f. aurea underwent hybridization with a population of the sinica species group between 2.5 and 0.95 MYA after divergence from the common ancestor of M. fascicularis. Hybridization and introgression might have been central in the evolution of M. f. aurea, similar to what occurred in the evolution of other macaque species and subspecies. PMID- 29186473 TI - Meta-analysis of thirty-two case-control and two ecological radon studies of lung cancer. AB - A re-analysis has been carried out of thirty-two case-control and two ecological studies concerning the influence of radon, a radioactive gas, on the risk of lung cancer. Three mathematically simplest dose-response relationships (models) were tested: constant (zero health effect), linear, and parabolic (linear-quadratic). Health effect end-points reported in the analysed studies are odds ratios or relative risk ratios, related either to morbidity or mortality. In our preliminary analysis, we show that the results of dose-response fitting are qualitatively (within uncertainties, given as error bars) the same, whichever of these health effect end-points are applied. Therefore, we deemed it reasonable to aggregate all response data into the so-called Relative Health Factor and jointly analysed such mixed data, to obtain better statistical power. In the second part of our analysis, robust Bayesian and classical methods of analysis were applied to this combined dataset. In this part of our analysis, we selected different subranges of radon concentrations. In view of substantial differences between the methodology used by the authors of case-control and ecological studies, the mathematical relationships (models) were applied mainly to the thirty-two case control studies. The degree to which the two ecological studies, analysed separately, affect the overall results when combined with the thirty-two case control studies, has also been evaluated. In all, as a result of our meta analysis of the combined cohort, we conclude that the analysed data concerning radon concentrations below ~1000 Bq/m3 (~20 mSv/year of effective dose to the whole body) do not support the thesis that radon may be a cause of any statistically significant increase in lung cancer incidence. PMID- 29186476 TI - Reversible Notch1 acetylation tunes proliferative signalling in cardiomyocytes. AB - Aims: The Notch signalling pathway regulates the balance between proliferation and differentiation in several tissues, including the heart. Our previous work has demonstrated that the proliferative potential of neonatal cardiomyocytes relies on Notch1 activity. A deep investigation on the biochemical regulation of the Notch signalling in cardiomyocytes is the focus of the current research. Methods and results: We show that the Notch1 intracellular domain is acetylated in proliferating neonatal rat cardiomyocytes and that acetylation tightly controls the amplitude and duration of Notch signalling. We found that acetylation extends the half-life of the protein, and enhanced its transcriptional activity, therefore counteracting apoptosis and sustaining cardiomyocyte proliferation. Sirt1 acted as a negative modulator of Notch1 signalling; its overexpression in cardiomyocytes reverted Notch acetylation and dampened its stability. A constitutively acetylated fusion protein between Notch1 and the acetyltransferase domain of p300 promoted cardiomyocyte proliferation, which was remarkably sustained over time. Viral vector-mediated expression of this protein enhanced heart regeneration after apical resection in neonatal mice. Conclusion: These results identify the reversible acetylation of Notch1 as a novel mechanism to modulate its signalling in the heart and tune the proliferative potential of cardiomyocytes. PMID- 29186475 TI - ProphTools: general prioritization tools for heterogeneous biological networks. AB - Background: Networks have been proven effective representations for the analysis of biological data. As such, there exist multiple methods to extract knowledge from biological networks. However, these approaches usually limit their scope to a single biological entity type of interest or they lack the flexibility to analyze user-defined data. Results: We developed ProphTools, a flexible open source command-line tool that performs prioritization on a heterogeneous network. ProphTools prioritization combines a Flow Propagation algorithm similar to a Random Walk with Restarts and a weighted propagation method. A flexible model for the representation of a heterogeneous network allows the user to define a prioritization problem involving an arbitrary number of entity types and their interconnections. Furthermore, ProphTools provides functionality to perform cross validation tests, allowing users to select the best network configuration for a given problem. ProphTools core prioritization methodology has already been proven effective in gene-disease prioritization and drug repositioning. Here we make ProphTools available to the scientific community as flexible, open-source software and perform a new proof-of-concept case study on long noncoding RNAs (lncRNAs) to disease prioritization. Conclusions: ProphTools is robust prioritization software that provides the flexibility not present in other state of-the-art network analysis approaches, enabling researchers to perform prioritization tasks on any user-defined heterogeneous network. Furthermore, the application to lncRNA-disease prioritization shows that ProphTools can reach the performance levels of ad hoc prioritization tools without losing its generality. PMID- 29186477 TI - Host Specificity in Subarctic Aphids. AB - Plants and herbivorous (or parasitic) insects form the majority of macroscopic life. The specificity of interaction between host plant and parasitic insect depends on the adaptations of both the host and the parasite. Over time, these interactions evolve and change as a result of an 'arms race' between host and parasite, and the resulting species-specific adaptations may be maintained, perpetuating these interactions across speciation events. This can lead to specialisation between species or clades. With speciation and species sorting over time, complex interactions evolve. Here, we elucidate a three-tier method to test these interactions using the aphids (Hemiptera: Aphididae) and plants of Churchill (Manitoba, Canada) as a model system. We analyzed these interactions by testing for three patterns in host specificity: monophagy, phylogenetic clustering, and cophylogeny. We defined monophagy strictly as one species feeding exclusively upon a single host plant species (an association likely driven by arms races in morphology, chemical resistance/tolerance, and visual appearance) and observed this in 7 of 22 aphid species. In all the remaining 'polyphagous' cases, there was a strong trend toward monophagy (80% of individuals were found on a single host plant species). Second, we observed two separate examples of phylogenetic clustering where groups of closely related aphid species fed upon individual plant species. Finally, we found no support for cophylogenetic relationships where both aphids and plants cospeciate to form congruent phylogenetic trees (evidence of coadaptation through an ongoing arms race). One explanation for uncovering species-specific interactions in a recently deglaciated, subarctic locality is that the species involved in the associations moved north together. Testing different levels of specificity in the most predominant species-species interactions on the planet will allow us to elucidate these patterns accurately and gives us insight into where to direct future research. PMID- 29186478 TI - Randomized controlled trials in children's heart surgery in the 21st century: a systematic review. AB - OBJECTIVES: Randomized controlled trials are the gold standard for evaluating health care interventions, yet are uncommon in children's heart surgery. We conducted a systematic review of clinical trials in paediatric cardiac surgery to evaluate the scope and quality of the current international literature. METHODS: We searched MEDLINE, CENTRAL and LILACS, and manually screened retrieved references and systematic reviews to identify all randomized controlled trials reporting the effect of any intervention on the conduct or outcomes of heart surgery in children published in any language since January 2000; secondary publications and those reporting inseparable adult data were excluded. Two reviewers independently screened studies for eligibility and extracted data; the Cochrane Risk of Bias tool was used to assess for potential biases. RESULTS: We identified 333 trials from 34 countries randomizing 23 902 children. Most were early phase (313, 94.0%), recruiting few patients (median 45, interquartile range 28-82), and only 11 (3.3%) directly evaluated a surgical intervention. One hundred and nine (32.7%) trials calculated a sample size, 52 (15.6%) reported a CONSORT diagram, 51 (15.3%) were publicly registered and 25 (7.5%) had a Data Monitoring Committee. The overall risk of bias was low in 22 (6.6%), high in 69 (20.7%) and unclear in 242 (72.7%). CONCLUSIONS: The recent literature in children's heart surgery contains few late-phase clinical trials. Most trials did not conform to the accepted standards of reporting, and the overall risk of bias was low in few studies. There is a need for high-quality, multicentre clinical trials to provide a robust evidence base for contemporary paediatric cardiac surgical practice. PMID- 29186479 TI - Febrile seizures prior to sudden cardiac death: a Danish nationwide study. AB - Aims: Febrile seizure (FS) is a common disorder affecting 2-5% of children up to 5 years of age. The aim of this study was to determine whether FS in early childhood are over-represented in young adults dying from sudden cardiac death (SCD). Methods and results: We included all deaths (n = 4595) nationwide and through review of all death certificates, we identified 245 SCD in Danes aged 1 30 years in 2000-09. Through the usage of nationwide registries, we identified all persons admitted with first FS among SCD cases (14/245; 5.7%) and in the corresponding living Danish population (71 027/2 369 785; 3.0%) and also in victims of transport accidents (26/917; 2.8%). The frequency of FS among SCD cases was significantly increased by an odds ratio of 1.96 [95% confidence interval (CI) 1.14-3.36; P = 0.021] compared with the living Danish population and with an odds ratio of 2.08 (95% CI 1.07-4.04; P = 0.046) compared with transport accident victims. SCD cases did not differ statistically in birth year (P = 0.272), age at SCD (P = 0.667) or prior medical conditions, except for epilepsy (P < 0.001), when comparing SCD with and without prior FS. The most common cause of death in autopsied SCD cases with FS was sudden arrhythmic death syndrome (5/8; 62.5%). Conclusion: In conclusion, this study demonstrates a significantly two-fold increase in the frequency of FS prior to death in young SCD cases compared with the two control groups, suggesting that FS could potentially contribute in a risk stratification model for SCD and warrant further studies. PMID- 29186480 TI - Gold nanoparticle printed coverslips to facilitate fluorescence-TEM correlative microscopy. AB - Correlative light and electron microscopy (CLEM) allows combining the advantages of fluorescence microscopy and electron microscopy for cell imaging. Rare phenomenon expressing cells can be studied by specifically tagged fluorophores with fluorescence microscopy. Subsequently, cells can be fixed and ultra structural details can be studied with transmission electron microscopy (TEM) at a higher resolution. However, precise landmarks are necessary to track the same cell throughout the CLEM process. In this technical report, we present a high contrast inkjet-printed gold nanoparticle patterns over commercial glass coverslip to facilitate cell tracking with correlative microscopy. High contrast and strong reflection from nano gold pattern can be used as a fixed landmark for cell identification with fluorescence microscopy. Nano gold printed letters over coverslips are visible in resin blocks, which can be further used to identify the cell of interest for performing sectioning of embedded cell blocks for TEM. PMID- 29186481 TI - Optimisation of trans-cinnamic acid and hydrocinnamyl alcohol production with recombinant Saccharomyces cerevisiae and identification of cinnamyl methyl ketone as a by-product. AB - Trans-cinnamic acid (tCA) and hydrocinnamyl alcohol (HcinOH) are valuable aromatic compounds with applications in the flavour, fragrance and cosmetic industry. They can be produced with recombinant yeasts from sugars via phenylalanine after expression of a phenylalanine ammonia lyase (PAL) and an aryl carboxylic acid reductase. Here, we show that in Saccharomyces cerevisiae a PAL enzyme from the bacterium Photorhabdus luminescens was superior to a previously used plant PAL enzyme for the production of tCA. Moreover, after expression of a UDP-glucose:cinnamate glucosyltransferase (FaGT2) from Fragaria x ananassa, tCA could be converted to cinnamoyl-D-glucose which is expected to be less toxic to the yeast cells. Production of tCA and HcinOH from glucose could be increased by eliminating feedback-regulated steps of aromatic amino acid biosynthesis and diminishing the decarboxylation step of the competing Ehrlich pathway. Finally, an unknown by-product resulting from further metabolisation of a carboligation product of cinnamaldehyde (cinALD) with activated acetaldehyde, mediated by pyruvate decarboxylases, could be identified as cinnamyl methyl ketone providing a new route for the biosynthesis of precursors, such as (2S,3R) 5-phenylpent-4 ene-2,3-diol, necessary for the chemical synthesis of specific biologically active drugs such as daunomycin. PMID- 29186482 TI - ALR encoding dCMP deaminase is critical for DNA damage repair, cell cycle progression and plant development in rice. AB - Deoxycytidine monophosphate deaminase (dCMP deaminase, DCD) is crucial to the production of dTTP needed for DNA replication and damage repair. However, the effect of DCD deficiency and its molecular mechanism are poorly understood in plants. Here, we isolated and characterized a rice albinic leaf and growth retardation (alr) mutant that is manifested by albinic leaves, dwarf stature and necrotic lesions. Map-based cloning and complementation revealed that ALR encodes a DCD protein. OsDCD was expressed ubiquitously in all tissues. Enzyme activity assays showed that OsDCD catalyses conversion of dCMP to dUMP, and the DeltaDCD protein in the alr mutant is a loss-of-function protein that lacks binding ability. We report that alr plants have typical DCD-mediated imbalanced dNTP pools with decreased dTTP; exogenous dTTP recovers the wild-type phenotype. A comet assay and Trypan Blue staining showed that OsDCD deficiency causes accumulation of DNA damage in the alr mutant, sometimes leading to cell apoptosis. Moreover, OsDCD deficiency triggered cell cycle checkpoints and arrested cell progression at the G1/S-phase. The expression of nuclear and plastid genome replication genes was down-regulated under decreased dTTP, and together with decreased cell proliferation and defective chloroplast development in the alr mutant this demonstrated the molecular and physiological roles of DCD mediated dNTP pool balance in plant development. PMID- 29186483 TI - Eukaryotic-like Kinase Expression in Enterohemorrhagic Escherichia coli: Potential for Enhancing Host Aggressive Inflammatory Response. AB - Enterohemorrhagic Escherichia coli (EHEC) or other attaching/effacing pathogen infections often cause host intestinal inflammation and pathology, which is thought to result in part from a host aggressive innate immune response. However, few effectors that play an important role in this pathology change have been reported. In this study, we discovered a previously unknown EHEC effector, Stk (putative serine/threonine kinase), which induces host aggressive inflammatory response during EHEC infection. Interestingly, homologous proteins of Stk are widely distributed in many pathogens. After translocating into the infected host cells, Stk efficiently phosphorylates IkappaBalpha and activates the NF-kappaB pathway. In EHEC-infected mice, Stk increases serum keratinocyte-derived cytokine (KC) levels and hyperactivates the inflammatory response of the colon, intensifying pathological injury of the colon. The virulence of Stk is based on its eukaryotic-like kinase activity. In conclusion, our data suggest that Stk is a new effector that induces the host aggressive inflammatory response during EHEC infection. PMID- 29186484 TI - Development of a resource allocation formula for substance misuse treatment services. AB - Background: Funding for substance misuse services comprises one-third of Public Health spend in England. The current allocation formula contains adjustments for actual activity, performance and need, proxied by the Standardized Mortality Ratio for under-75s (SMR < 75). Additional measures, such as deprivation, may better identify differential service need. Methods: We developed an age standardized and an age-stratified model (over-18s, under-18s), with the outcome of expected/actual cost at postal sector/Local Authority level. A third, person based model incorporated predictors of costs at the individual level. Each model incorporated both needs and supply variables, with the relative effects of their inclusion assessed. Results: Mean estimated annual cost (2013/14) per English Local Authority area was L5 032 802 (sd: 3 951 158). Costs for drug misuse treatment represented the majority (83%) of costs. Models achieved adjusted R squared values of 0.522 (age-standardized), 0.533 (age-stratified over-18s), 0.232 (age-stratified under-18s) and 0.470 (person-based). Conclusion: Improvements can be made to the existing resource allocation formulae to better reflect population need. The person-based model permits inclusion of a range of needs variables, in addition to strong predictors of cost based on the receipt of treatment in the previous year. Adoption of this revised person-based formula for substance misuse would shift resources towards more deprived areas. PMID- 29186486 TI - Long-read sequence assembly of the firefly Pyrocoelia pectoralis genome. AB - Background: Fireflies are a family of insects within the beetle order Coleoptera, or winged beetles, and they are one of the most well-known and loved insect species because of their bioluminescence. However, the firefly is in danger of extinction because of the massive destruction of its living environment. In order to improve the understanding of fireflies and protect them effectively, we sequenced the whole genome of the terrestrial firefly Pyrocoelia pectoralis. Findings: Here, we developed a highly reliable genome resource for the terrestrial firefly Pyrocoelia pectoralis (E. Oliv., 1883; Coleoptera: Lampyridae) using single molecule real time (SMRT) sequencing on the PacBio Sequel platform. In total, 57.8 Gb of long reads were generated and assembled into a 760.4-Mb genome, which is close to the estimated genome size and covered 98.7% complete and 0.7% partial insect Benchmarking Universal Single-Copy Orthologs. The k-mer analysis showed that this genome is highly heterozygous. However, our long-read assembly demonstrates continuousness with a contig N50 length of 3.04 Mb and the longest contig length of 13.69 Mb. Furthermore, 135 589 SSRs and 341 Mb of repeat sequences were detected. A total of 23 092 genes were predicted; 88.44% of genes were annotated with one or more related functions. Conclusions: We assembled a high-quality firefly genome, which will not only provide insights into the conservation and biodiversity of fireflies, but also provide a wealth of information to study the mechanisms of their sexual communication, bio-luminescence, and evolution. PMID- 29186485 TI - Indications and practical approach to non-invasive ventilation in acute heart failure. AB - In acute heart failure (AHF) syndromes significant respiratory failure (RF) is essentially seen in patients with acute cardiogenic pulmonary oedema (ACPE) or cardiogenic shock (CS). Non-invasive ventilation (NIV), the application of positive intrathoracic pressure through an interface, has shown to be useful in the treatment of moderate to severe RF in several scenarios. There are two main modalities of NIV: continuous positive airway pressure (CPAP) and pressure support ventilation (NIPSV) with positive end expiratory pressure. Appropriate equipment and experience is needed for NIPSV, whereas CPAP may be administered without a ventilator, not requiring special training. Both modalities have shown to be effective in ACPE, by a reduction of respiratory distress and the endotracheal intubation rate compared to conventional oxygen therapy, but the impact on mortality is less conclusive. Non-invasive ventilation is also indicated in patients with AHF associated to pulmonary disease and may be considered, after haemodynamic stabilization, in some patients with CS. There are no differences in the outcomes in the studies comparing both techniques, but CPAP is a simpler technique that may be preferred in low-equipped areas like the pre hospital setting, while NIPSV may be preferable in patients with significant hypercapnia. The new modality 'high-flow nasal cannula' seems promising in cases of AHF with less severe RF. The correct selection of patients and interfaces, early application of the technique, the achievement of a good synchrony between patients and the ventilator avoiding excessive leakage, close monitoring, proactive management, and in some cases mild sedation, may warrant the success of the technique. PMID- 29186487 TI - Epizoic Fauna Survey on Phyllostomid Bats (Chiroptera: Phyllostomidae) in a Shaded Coffee Plantation of Southeastern Chiapas, Mexico. AB - This is the first complete assessment of the ectoparasite fauna on phyllostomid bats in a shaded coffee plantation in Mexico. The study was carried out at Finca San Carlos, in the municipality of Tapachula, southeastern Chiapas, Mexico. The bats were captured over three consecutive nights every month, from December 2005 to November 2006, using four mist nets. We captured 192 phyllostomid bats, representing 18 species, upon which 1,971 ectoparasites, belonging to 11 families and 65 species, were found. We found that 160 of the 192 captured bats were hosts to ectoparasites, giving an infestation prevalence of 83.3%. Of the 65 ectoparasitic species, 14 were classified as monoxenous and 17 as stenoxenous. More ectoparasites were recorded in the dry season (n = 1,439) than the wet season (n = 532), and we recorded some families of ectoparasite on particular areas of the bat body. An ordination of bat species, based on their ectoparasitic species community structure, formed groups at the subfamily level or lower taxonomic categories. We suggest that the close ectoparasite-host relationships could be examined as an additional tool to elucidate the taxonomic relationships between the hosts. PMID- 29186489 TI - Challenges to tuberculosis control in Angola: the narrative of medical professionals. AB - Background: There is a tuberculosis (TB) epidemic in Angola that has been getting worse for more than a decade despite the active implementation of the DOTS strategy. The aim of this study was to directly interrogate healthcare workers involved in TB control on what they consider to be the drivers of the TB epidemic in Angola. Methods: Twenty four in-depth qualitative interviews were conducted with medical staff working in this field in the provinces of Luanda and Benguela. Results: The healthcare professionals see the migrant working poor as a particular problem for the control of TB. These migrants are constructed as 'Rural People' and are seen as non-compliant and late-presenting. This is a stigmatized and marginal group contending with the additional stigma associated with TB infection. The healthcare professionals interviewed also see the interruption of treatment and self-medication generally as a better explanation for the TB epidemic than urbanization or lack of medication. Conclusions: The local narrative is in contrast to previous explanations used elsewhere in the developing world. To be effective policy must recognize the local issues of the migrant workforce, interruption of treatment and the stigma associated with TB in Angola. PMID- 29186488 TI - A putative R3 MYB repressor is the candidate gene underlying atroviolacium, a locus for anthocyanin pigmentation in tomato fruit. AB - Anthocyanins are potential health-promoting compounds in the human diet. The atv (atroviolacium) locus, derived from the wild tomato species Solanum cheesmaniae, has been shown to enhance anthocyanin pigmentation in tomato fruit when it co exists with either the Aft (Anthocyanin fruit) or the Abg (Aubergine) locus. In the present study, the atv locus was fine-mapped to an approximately 5.0-kb interval on chromosome 7. A putative R3 MYB repressor was identified in this interval and is hereby designated as SlMYBATV. The allele of SlMYBATV underlying the atv locus harbored a 4-bp insertion in its coding region, which is predicted to result in a frame-shift and premature protein truncation. The other candidate R3 MYB and R2R3 MYB repressors of anthocyanin biosynthesis were also identified in tomato via a genome-wide search. Transcriptional analysis showed that most of the structural genes and several regulatory genes of anthocyanin biosynthesis were up-regulated in the tomato SlMYBATV mutant lines. These findings may facilitate the elucidation of the molecular mechanisms underlying anthocyanin pigmentation in tomato fruit and help in the marker-assisted selection of anthocyanin-enriched tomato cultivars. PMID- 29186490 TI - MEASUREMENTS OF RADIATION EXPOSURE OF RADIOGRAPHY STUDENTS DURING THEIR CLINICAL TRAINING USING THERMOLUMINESCENT DOSIMETRY. AB - Radiation dose monitoring for radiography students during clinical training is necessary to demonstrate the extent of radiation protection issues present, as well as to instill in them an awareness of safe practices that they will carry with them throughout their careers. The study assess the radiation dose incurred by the undergraduate during clinical training. 312 students were monitored using (thermoluminescence dosimetry) between 2009 and 2015. The results establish that the radiation dose received by the students is well below the dose recommended by national and international authorities. Findings indicate that the dose did not reach the value of 1 mSv, which indicate that current radiation protection measures are acceptable and there was no risk of overexposure, as well as reinforces the importance of nuturing a culture of radiation protection and provides evidence to students that their future as professionals will be a safe one. PMID- 29186491 TI - CLAMP - a toolkit for efficiently building customized clinical natural language processing pipelines. AB - Existing general clinical natural language processing (NLP) systems such as MetaMap and Clinical Text Analysis and Knowledge Extraction System have been successfully applied to information extraction from clinical text. However, end users often have to customize existing systems for their individual tasks, which can require substantial NLP skills. Here we present CLAMP (Clinical Language Annotation, Modeling, and Processing), a newly developed clinical NLP toolkit that provides not only state-of-the-art NLP components, but also a user-friendly graphic user interface that can help users quickly build customized NLP pipelines for their individual applications. Our evaluation shows that the CLAMP default pipeline achieved good performance on named entity recognition and concept encoding. We also demonstrate the efficiency of the CLAMP graphic user interface in building customized, high-performance NLP pipelines with 2 use cases, extracting smoking status and lab test values. CLAMP is publicly available for research use, and we believe it is a unique asset for the clinical NLP community. PMID- 29186492 TI - Mechanisms of acid-base regulation in peritoneal dialysis. AB - Background: Peritoneal dialysis (PD) contributes to restore acid-base homeostasis in patients with end-stage renal disease. The transport pathways for buffers and carbon dioxide (CO2) across the peritoneal membrane remain poorly understood. Methods: Combining well-established PD protocols, whole-body plethysmography and renal function studies in mice, we investigated molecular mechanisms of acid-base regulation in PD, including the potential role of the water channel aquaporin-1 (AQP1). Results: After instillation in peritoneal cavity, the pH of acidic dialysis solutions increased within minutes to rapidly equilibrate with blood pH, whereas the neutral pH of biocompatible solutions remained constant. Predictions from the three-pore model of peritoneal transport suggested that local production of HCO3- accounts at least in part for the changes in intraperitoneal pH observed with acidic solutions. Carbonic anhydrase (CA) isoforms were evidenced in the peritoneal membrane and their inhibition with acetazolamide significantly decreased local production of HCO3- and delayed changes in intraperitoneal pH. On the contrary, genetic deletion of AQP1 had no effect on peritoneal transport of buffers and diffusion of CO2. Besides intraperitoneal modifications, the use of acidic dialysis solutions enhanced acid excretion both at pulmonary and renal levels. Conclusions: These findings suggest that changes in intraperitoneal pH during PD are mediated by bidirectional buffer transport and by CA-mediated production of HCO3- in the membrane. The use of acidic solutions enhances acid excretion through respiratory and renal responses, which should be considered in patients with renal failure. PMID- 29186493 TI - A Molecular Survey of Rickettsias in Shelter Dogs and Distribution of Rhipicephalus sanguineus (Acari: Ixodidae) sensu lato in Southeast Turkey. AB - Canine tick-borne pathogens are the source of emerging diseases and have important zoonotic relevance. Dogs play a major role in the transmission of several zoonotic tick-borne pathogens, as reservoirs and/or sentinels. To simultaneously detect Anaplasma and Ehrlichia species, a reverse line blot assay was conducted on 219 blood samples collected from autochthonous asymptomatic shelter dogs. One hundred and three (47.0%, CI 40.3-53.9) dogs were positive for one or both rickettsial pathogens. Seventy-one (32.4%, CI 26.3-39.0) dogs were infected with Anaplasma platys and 23 (10.5%, CI 6.8-15.3) with Ehrlichia canis. Concurrent infection with A. platys and E. canis was detected in nine (4.1%, CI 1.9-7.6) dogs. Partial sequences of the 16S ribosomal RNA gene shared 100% identity with the corresponding published sequences for A. platys and E. canis. Infection with Anaplasma phagocytophilum was not detected in the examined dogs. In total, 1018 (range 1-70, mean intensity 13.1, mean abundance 4.6) Rhipicephalus sanguineus (Latreille) (Acari: Ixodidae) sensu lato ticks (45.7% nymphs, 54.3% adults) were collected from the dogs. There was no significant association between Anaplasma/Ehrlichia infection and dog sex or age, but a significant correlation was found between rickettsia infection and presence of R. sanguineus. Improved tick control strategies to reduce the risk of these pathogens spreading among dogs and humans are needed in the region. PMID- 29186494 TI - Mitral valve repair in Barlow's disease with bileaflet prolapse: the effect of annular stabilization on functional mitral valve leaflet prolapse. AB - OBJECTIVES: Barlow's disease is the most severe form of degenerative mitral valve disease, commonly characterized by bileaflet prolapse. Abnormal mitral annular dynamics is typically present and results in functional prolapse of the mitral leaflets that may be addressed with annular stabilization alone. METHODS: Between January 2001 and December 2015, 128 patients with Barlow's disease and bileaflet prolapse underwent valve repair. This included anterior mitral valve leaflet (AMVL) repair in 70 patients, whereas 58 patients were identified as having functional prolapse and underwent no specific AMVL repair. During the course of the study, the proportion of patients undergoing specific AMVL repair decreased (77% in the first and 33% in the second 64 patients). Semirigid ring annuloplasty was performed in all cases. The median clinical and echocardiographic follow-up duration was 6.5 years [interquartile range (IQR) 2.9-10.5 years; 93.9% complete] and 4.7 years (IQR 2.2-10.2 years; 94.4% complete), respectively. RESULTS: Early mortality was 1.6%. Postoperative echocardiogram demonstrated no residual mitral regurgitation in all but 1 patient (AMVL repair group). There was no significant difference in the overall survival rate at 6 years after operation between both groups. At 6 years, the freedom from recurrent >=Grade 2+ mitral regurgitation rate was 90.7% (IQR 82.9-98.5%) and 89.1% (IQR 75.8-100%) for patients with and patients with no AMVL repair, respectively (P = 0.43). Three patients required late mitral valve reintervention, all from the AMVL repair group. CONCLUSIONS: Annular stabilization can effectively resolve the functional prolapse of the AMVL. Careful discrimination between functional and true AMVL prolapse allows for a technically less challenging operation that provides excellent repair durability.

AB - We investigated sugar metabolism in leaves and fruits of two Japanese plum (Prunus salicina Lindl.) cultivars, the climacteric Santa Rosa and its bud sport mutant the non-climacteric Sweet Miriam, during development on the tree. We previously characterized differences between the two cultivars. Here, we identified key sugar metabolic pathways. Pearson coefficient correlations of metabolomics and transcriptomic data and weighted gene co-expression network analysis (WGCNA) of RNA sequencing (RNA-Seq) data allowed the identification of 11 key sugar metabolism-associated genes: sucrose synthase, sucrose phosphate synthase, cytosolic invertase, vacuolar invertase, invertase inhibitor, alpha galactosidase, beta-galactosidase, galactokinase, trehalase, galactinol synthase, and raffinose synthase. These pathways were further assessed and validated through the biochemical characterization of the gene products and with metabolite analysis. Our results demonstrated the reprogramming of sugar metabolism in both leaves and fruits in the non-climacteric plum, which displayed a shift towards increased sorbitol synthesis. Climacteric and non-climacteric fruits showed differences in their UDP-galactose metabolism towards the production of galactose and raffinose, respectively. The higher content of galactinol, myo-inositol, raffinose, and trehalose in the non-climacteric fruits could improve the ability of the fruits to cope with the oxidative processes associated with fruit ripening. Overall, our results support a relationship between sugar metabolism, ethylene, and ripening behavior.

AB - Neuronal constituents of the human anterior cingulate cortex displayed morphological changes related to the 43-kDa transactive response DNA-binding protein (TDP-43) in advanced pathological stages of sporadic amyotrophic lateral sclerosis (sALS). By using nonphosphorylation-dependent TDP-43 immunocytochemistry, it was seen that the changes in susceptible pyramidal cells of the superficial cellular layers II-IIIab differed from those in the deep layers IIIc-Vb: A complete loss of nuclear TDP-43 expression (i.e. nuclear clearing) in the small projection neurons of layers II-IIIab was consistently accompanied by the development of somatic skein-like TDP-43-immunopositive inclusions. In contrast, in the large pyramidal cells of layers IIIc-Vb and von Economo neurons of layer Vb, skein-like inclusions were lacking or, when aggregated TDP-43 was present, the aggregates presented as dash-like TDP-43 immunopositive particles in the vicinity of the cell nucleus. The cytoskeleton of projection neurons in layers II-IIIab is neurofilament-sparse in contrast to that of the large neurons in layers IIIc-Vb, which are rich in neurofilaments and also heat shock proteins that function as their molecular chaperones. The disparities between the two neuronal populations may contribute to the two differing immunocytochemical profiles reported here. Some implications of the findings for the pathogenesis and progression of TDP-43 pathology in sALS are discussed. PMID- 29186497 TI - For as Long as Necessary: Examining 30 years of MSD's Focus on Achieving Elimination of Onchocerciasis and Lymphatic Filariasis. AB - Established by MSD, also known as Merck & Co., Inc., Kenilworth, NJ USA in 1987, the Mectizan Donation Program (MDP) is the longest running disease-specific program of its kind. Initially aimed at control of onchocerciasis (river blindness), the company expanded its commitment through the MDP in 1998 to include lymphatic filariasis (LF). Both diseases are now candidates for elimination and the company is engaged in several global partnerships to help advance towards that goal. To support the steadily growing demand from country led disease elimination programs, the company has put in place several administrative and operational improvements. In addition, the company is involved 'beyond the pill', including making financial and management contributions to partners such as the END Fund and the Expanded Special Project to Eliminate NTDs (ESPEN) to support the technical needs of elimination programs. While the time bound elimination targets are challenging, clear progress is being made for both onchocerciasis and LF, with several national and subnational areas in Latin America and Africa having stopped transmission of one or both diseases. The company's donation of Mectizan and contributions of financial, management and technical resources reflect the company's long-standing commitment to pursue inventive ways to expand and enhance access to medicine. Continued support from MSD and other partners will enable countries to advance towards their elimination targets for LF and onchocerciasis. PMID- 29186499 TI - Collaborating for oral health in support of vulnerable older people: co production of oral health training in care homes. AB - Background: In recent years, the value of co-production has become embedded in the social care agenda. Care home residents are at significantly higher risk of dental diseases and often rely on the care team for support. It is therefore vital that staff are trained and confident in delivering evidence based oral care to their clients. Methods: Three London care homes co-produced a pilot oral health training programme, informed by in-depth interviews and group discussions. The initiative was evaluated using pre/post-questionnaires of carers and semi structured interviews of managers and the dental teams. Results: Two care homes were available for delivery of the programme, which resulted in training of 64% (n = 87) of care staff. The training programme involved videos and resources and was delivered flexibly with the support of an oral health educator and a dental therapist. There was an improvement in knowledge and self-reported confidence post-training; however, only 54% (n = 45) completed the post-training questionnaire. Conclusions: This study suggests that co-production of an oral care training package for care home staff, is possible and welcome, but challenging in this complex and changing environment. Further work is needed to explore the feasibility, sustainability and impact of doing so. PMID- 29186498 TI - The Medicago truncatula GRAS protein RAD1 supports arbuscular mycorrhiza symbiosis and Phytophthora palmivora susceptibility. AB - The roots of most land plants are colonized by symbiotic arbuscular mycorrhiza (AM) fungi. To facilitate this symbiosis, plant genomes encode a set of genes required for microbial perception and accommodation. However, the extent to which infection by filamentous root pathogens also relies on some of these genes remains an open question. Here, we used genome-wide association mapping to identify genes contributing to colonization of Medicago truncatula roots by the pathogenic oomycete Phytophthora palmivora. Single-nucleotide polymorphism (SNP) markers most significantly associated with plant colonization response were identified upstream of RAD1, which encodes a GRAS transcription regulator first negatively implicated in root nodule symbiosis and recently identified as a positive regulator of AM symbiosis. RAD1 transcript levels are up-regulated both in response to AM fungus and, to a lower extent, in infected tissues by P. palmivora where its expression is restricted to root cortex cells proximal to pathogen hyphae. Reverse genetics showed that reduction of RAD1 transcript levels as well as a rad1 mutant are impaired in their full colonization by AM fungi as well as by P. palmivora. Thus, the importance of RAD1 extends beyond symbiotic interactions, suggesting a general involvement in M. truncatula microbe-induced root development and interactions with unrelated beneficial and detrimental filamentous microbes. PMID- 29186500 TI - Modeling the factors associating with health-related habits among Japanese students. AB - The aim of the present study was to clarify the structural relationship between health-related habits and psychosocial factors during adolescence/early adulthood. An anonymous, self-administered questionnaire was provided to 1141 third- and fourth-year students at eight academic departments from six universities in regional Japanese cities. Surveys included items addressing participants' demographic characteristics, psychosocial factors (individual-level social capital, self-efficacy, mental health (from health-related quality of life SF-36v2), and sense of coherence (SOC)), and health-related habits. A multiple indicator analysis based on structural equation modeling was conducted to examine the structural relationship between health-related habits and these factors. Valid responses were obtained from 952 participants. The final model demonstrated a high level of goodness of fit. While the path from SOC to health-related habits was significant, those from self-efficacy to health-related habits and from mental health to health-related habits were not significant. The path coefficient from SOC to health-related habits was greater than the path coefficient from background characteristics. In the multiple population comparison that considered gender, a nearly identical model was supported for men and women. Psychosocial factors related to health-related habits were social capital, self-efficacy, mental health, and SOC. Furthermore, it was suggested that SOC functions as an intervening factor for maintaining a healthy lifestyle. It was observed that individual psychosocial factors influence health-related habits more than their background characteristics. Findings highlight that supporting the building of social relationships and social environments is essential to promote a healthy lifestyle among university students.

PMID- 29186503 TI - MINTbase v2.0: a comprehensive database for tRNA-derived fragments that includes nuclear and mitochondrial fragments from all The Cancer Genome Atlas projects. AB - MINTbase is a repository that comprises nuclear and mitochondrial tRNA-derived fragments ('tRFs') found in multiple human tissues. The original version of MINTbase comprised tRFs obtained from 768 transcriptomic datasets. We used our deterministic and exhaustive tRF mining pipeline to process all of The Cancer Genome Atlas datasets (TCGA). We identified 23 413 tRFs with abundance of >= 1.0 reads-per-million (RPM). To facilitate further studies of tRFs by the community, we just released version 2.0 of MINTbase that contains information about 26 531 distinct human tRFs from 11 719 human datasets as of October 2017. Key new elements include: the ability to filter tRFs on-the-fly by minimum abundance thresholding; the ability to filter tRFs by tissue keywords; easy access to information about a tRF's maximum abundance and the datasets that contain it; the ability to generate relative abundance plots for tRFs across cancer types and convert them into embeddable figures; MODOMICS information about modifications of the parental tRNA, etc. Version 2.0 of MINTbase contains 15x more datasets and nearly 4x more distinct tRFs than the original version, yet continues to offer fast, interactive access to its contents. Version 2.0 is available freely at http://cm.jefferson.edu/MINTbase/. PMID- 29186504 TI - No evidence of neurocognitive adverse events associated with alirocumab treatment in 3340 patients from 14 randomized Phase 2 and 3 controlled trials: a meta analysis of individual patient data. AB - Aims: Despite patient reports of neurocognitive disorders with lipid-lowering treatments (LLTs), large clinical trials have found no significant association between neurocognitive disorders and LLTs. We assessed incidence of neurocognitive treatment-emergent adverse events (TEAEs) from 14 Phase 2 and 3 trials of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor alirocumab. Methods and results: Patients (most on background maximally tolerated statin) received alirocumab 75/150 mg every 2 weeks (n = 3340; 4029 patient-years of exposure), placebo (n = 1276), or ezetimibe (n = 618). Data were pooled by the control used. Neurocognitive TEAEs were reported by 22 (0.9%) alirocumab-treated patients vs. 9 (0.7%) with placebo in placebo-controlled trials [hazard ratio (HR) 1.24, 95% confidence interval (CI) 0.57-2.68] and 10 (1.2%) with alirocumab vs. 8 (1.3%) with ezetimibe in ezetimibe-controlled trials (HR 0.81, 95% CI 0.32 2.08). Rates of neurocognitive TEAEs were similar in patients receiving alirocumab with LDL cholesterol (LDL-C) levels <25 mg/dL (<0.65 mmol/L; n = 5/839; 0.6%; 0.5/100 patient-years) vs. >=25 mg/dL (n = 26/2501; 1.0%; 0.8/100 patient-years). One patient (0.1%; ezetimibe-controlled pool) receiving alirocumab had a neurocognitive TEAE leading to discontinuation vs. two (0.2%) patients receiving placebo and three (0.4%) patients receiving ezetimibe. Neurocognitive TEAE incidence was also similar between alirocumab and controls when stratified by age. Conclusions: Neurocognitive TEAE incidences were low (<=1.2%), with no significant differences between alirocumab vs. controls up to 104 weeks. No association was found between neurocognitive TEAEs and LDL-C <25 mg/dL based on the completed Phase 2 and 3 trials examined, although long-term effects of very low LDL-C levels induced by PCSK9 inhibitors are currently unknown. PMID- 29186505 TI - Robust detection of chromosomal interactions from small numbers of cells using low-input Capture-C. AB - Chromosome conformation capture (3C) techniques are crucial to understanding tissue-specific regulation of gene expression, but current methods generally require large numbers of cells. This hampers the investigation of chromatin architecture in rare cell populations. We present a new low-input Capture-C approach that can generate high-quality 3C interaction profiles from 10 000-20 000 cells, depending on the resolution used for analysis. We also present a PCR free, sequencing-free 3C technique based on NanoString technology called C String. By comparing C-String and Capture-C interaction profiles we show that the latter are not skewed by PCR amplification. Furthermore, we demonstrate that chromatin interactions detected by Capture-C do not depend on the degree of cross linking by performing experiments with varying formaldehyde concentrations. PMID- 29186501 TI - The Amygdala as a Locus of Pathologic Misfolding in Neurodegenerative Diseases. AB - Over the course of most common neurodegenerative diseases the amygdala accumulates pathologically misfolded proteins. Misfolding of 1 protein in aged brains often is accompanied by the misfolding of other proteins, suggesting synergistic mechanisms. The multiplicity of pathogenic processes in human amygdalae has potentially important implications for the pathogenesis of Alzheimer disease, Lewy body diseases, chronic traumatic encephalopathy, primary age-related tauopathy, and hippocampal sclerosis, and for the biomarkers used to diagnose those diseases. Converging data indicate that the amygdala may represent a preferential locus for a pivotal transition from a relatively benign clinical condition to a more aggressive disease wherein multiple protein species are misfolded. Thus, understanding of amygdalar pathobiology may yield insights relevant to diagnoses and therapies; it is, however, a complex and imperfectly defined brain region. Here, we review aspects of amygdalar anatomy, connectivity, vasculature, and pathologic involvement in neurodegenerative diseases with supporting data from the University of Kentucky Alzheimer's Disease Center autopsy cohort. Immunohistochemical staining of amygdalae for Abeta, Tau, alpha synuclein, and TDP-43 highlight the often-coexisting pathologies. We suggest that the amygdala may represent an "incubator" for misfolded proteins and that it is possible that misfolded amygdalar protein species are yet to be discovered. PMID- 29186506 TI - Identification of large rearrangements in cancer genomes with barcode linked reads. AB - Large genomic rearrangements involve inversions, deletions and other structural changes that span Megabase segments of the human genome. This category of genetic aberration is the cause of many hereditary genetic disorders and contributes to pathogenesis of diseases like cancer. We developed a new algorithm called ZoomX for analysing barcode-linked sequence reads-these sequences can be traced to individual high molecular weight DNA molecules (>50 kb). To generate barcode linked sequence reads, we employ a library preparation technology (10X Genomics) that uses droplets to partition and barcode DNA molecules. Using linked read data from whole genome sequencing, we identify large genomic rearrangements, typically greater than 200kb, even when they are only present in low allelic fractions. Our algorithm uses a Poisson scan statistic to identify genomic rearrangement junctions, determine counts of junction-spanning molecules and calculate a Fisher's exact test for determining statistical significance for somatic aberrations. Utilizing a well-characterized human genome, we benchmarked this approach to accurately identify large rearrangement. Subsequently, we demonstrated that our algorithm identifies somatic rearrangements when present in lower allelic fractions as occurs in tumors. We characterized a set of complex cancer rearrangements with multiple classes of structural aberrations and with possible roles in oncogenesis. PMID- 29186507 TI - Pyridylhydroxybutyl and pyridyloxobutyl DNA phosphate adduct formation in rats treated chronically with enantiomers of the tobacco-specific nitrosamine metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol. AB - The tobacco-specific lung carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1 butanone (NNK) is metabolically converted to 4-(methylnitrosamino)-1-(3-pyridyl) 1-butanol (NNAL) in a reaction which is both stereoselective and reversible. NNAL is also a lung carcinogen, with both (R)-NNAL and (S)-NNAL inducing a high incidence of lung tumours in rats. Both NNAL and NNK undergo metabolic activation to intermediates which react with DNA to form pyridylhydroxybutyl and pyridyloxobutyl DNA adducts, respectively. DNA adduct formation by NNAL and NNK is an important step in their mechanisms of carcinogenesis. In this study, we quantified both pyridylhydroxybutyl and pyridyloxobutyl DNA phosphate adducts in the lung of rats treated with 5 ppm of (R)-NNAL or (S)-NNAL in drinking water for 10, 30, 50 and 70 weeks. In (R)-NNAL-treated rats, the pyridylhydroxybutyl and pyridyloxobutyl phosphate adducts were 4530-6920 fmol/mg DNA and 46-175 fmol/mg DNA, accounting for 45-51% and 0.3-1% of the total measured DNA phosphate and base adducts, respectively. In (S)-NNAL-treated rats, the two types of phosphate adducts were 3480-4180 fmol/mg DNA and 1180-4650 fmol/mg DNA, accounting for 30 36% and 11-38% of the total adducts, respectively. Distinct patterns of adduct formation were observed, with higher levels of NNAL-derived pyridylhydroxybutyl phosphate adducts and lower levels of NNK-derived pyridyloxobutyl phosphate adducts in the (R)-NNAL treatment group than the (S)-NNAL group. The persistence and increase over time of certain pyridylhydroxybutyl phosphate adducts over the course of the study suggest that these adducts could be useful biomarkers of chronic exposure to NNAL and NNK. The results of this study provide important new information regarding DNA damage by NNAL and NNK, and contribute to understanding mechanisms of tobacco-related carcinogenesis. PMID- 29186508 TI - Are all certified EHRs created equal? Assessing the relationship between EHR vendor and hospital meaningful use performance. AB - Objective: The federal electronic health record (EHR) certification process was intended to ensure a baseline level of system quality and the ability to support meaningful use criteria. We sought to assess whether there was variation across EHR vendors in the degree to which hospitals using products from those vendors were able to achieve high levels of performance on meaningful use criteria. Materials and Methods: We created a cross-sectional national hospital sample from the Office of the National Coordinator for Health Information Technology EHR Products Used for Meaningful Use Attestation public use file and the Centers for Medicare & Medicaid Services Medicare EHR Incentive Program Eligible Hospitals public use file. We used regression models to assess the relationship between vendor and hospital performance on 6 Stage 2 Meaningful Use criteria, controlling for hospital characteristics. We also calculated how much variation in performance is explained by vendor choice. Results: We found significant associations between specific vendor and level of hospital performance for all 6 meaningful use criteria. Epic was associated with significantly higher performance on 5 of the 6 criteria; relationships for other vendors were mixed, with some associated with significantly worse performance on multiple criteria. EHR vendor choice accounted for between 7% and 34% of performance variation across the 6 criteria. Discussion: A nontrivial proportion of variation in hospital meaningful use performance is explained by vendor choice, and certain vendors are more often associated with better meaningful use performance than others. Our results suggest that policy-makers should improve the certification process by including more "real-world" scenario testing and provider feedback or ratings to reduce this variation. Hospitals can use these results to guide interactions with vendors. Conclusion: Vendor choice accounts for a meaningful proportion of variation in hospital meaningful use performance, and specific vendors are consistently associated with higher or lower performance across criteria. PMID- 29186509 TI - Moxifloxacin target site concentrations in patients with pulmonary TB utilizing microdialysis: a clinical pharmacokinetic study. AB - Background: Moxifloxacin is a second-line anti-TB drug that is useful in the treatment of drug-resistant TB. However, little is known about its target site pharmacokinetics. Lower drug concentrations at the infection site (i.e. in severe lung lesions including cavitary lesions) may lead to development and amplification of drug resistance. Improved knowledge regarding tissue penetration of anti-TB drugs will help guide drug development and optimize drug dosing. Methods: Patients with culture-confirmed drug-resistant pulmonary TB scheduled to undergo adjunctive surgical lung resection were enrolled in Tbilisi, Georgia. Five serum samples per patient were collected at different timepoints including at the time of surgical resection (approximately at Tmax). Microdialysis was performed in the ex vivo tissue immediately after resection. Non-compartmental analysis was performed and a tissue/serum concentration ratio was calculated. Results: Among the seven patients enrolled, the median moxifloxacin dose given was 7.7 mg/kg, the median age was 25.2 years, 57% were male and the median creatinine clearance was 95.4 mL/min. Most patients (71%) had suboptimal steady state serum Cmax (total drug) concentrations. The median free moxifloxacin serum concentration at time of surgical resection was 1.23 MUg/mL (range = 0.12-1.80) and the median free lung tissue concentration was 3.37 MUg/mL (range = 0.81 5.76). The median free-tissue/free-serum concentration ratio was 3.20 (range = 0.66-28.08). Conclusions: Moxifloxacin showed excellent penetration into diseased lung tissue (including cavitary lesions) among patients with pulmonary TB. Moxifloxacin lung tissue concentrations were higher than those seen in serum. Our findings highlight the importance of moxifloxacin in the treatment of MDR-TB and potentially any patient with pulmonary TB and severe lung lesions. PMID- 29186510 TI - The European Bioinformatics Institute in 2017: data coordination and integration. AB - The European Bioinformatics Institute (EMBL-EBI) supports life-science research throughout the world by providing open data, open-source software and analytical tools, and technical infrastructure (https://www.ebi.ac.uk). We accommodate an increasingly diverse range of data types and integrate them, so that biologists in all disciplines can explore life in ever-increasing detail. We maintain over 40 data resources, many of which are run collaboratively with partners in 16 countries (https://www.ebi.ac.uk/services). Submissions continue to increase exponentially: our data storage has doubled in less than two years to 120 petabytes. Recent advances in cellular imaging and single-cell sequencing techniques are generating a vast amount of high-dimensional data, bringing to light new cell types and new perspectives on anatomy. Accordingly, one of our main focus areas is integrating high-quality information from bioimaging, biobanking and other types of molecular data. This is reflected in our deep involvement in Open Targets, stewarding of plant phenotyping standards (MIAPPE) and partnership in the Human Cell Atlas data coordination platform, as well as the 2017 launch of the Omics Discovery Index. This update gives a birds-eye view of EMBL-EBI's approach to data integration and service development as genomics begins to enter the clinic. PMID- 29186511 TI - An RNA polymerase II-associated TFIIF-like complex is indispensable for SL RNA gene transcription in Trypanosoma brucei. AB - Trypanosomes are protistan parasites that diverged early in evolution from most eukaryotes. Their streamlined genomes are packed with arrays of tandemly linked genes that are transcribed polycistronically by RNA polymerase (pol) II. Individual mRNAs are processed from pre-mRNA by spliced leader (SL) trans splicing and polyadenylation. While there is no strong evidence that general transcription factors are needed for transcription initiation at these gene arrays, a RNA pol II transcription pre-initiation complex (PIC) is formed on promoters of SLRNA genes, which encode the small nuclear SL RNA, the SL donor in trans splicing. The factors that form the PIC are extremely divergent orthologues of the small nuclear RNA-activating complex, TBP, TFIIA, TFIIB, TFIIH, TFIIE and Mediator. Here, we functionally characterized a heterodimeric complex of unannotated, nuclear proteins that interacts with RNA pol II and is essential for PIC formation, SL RNA synthesis in vivo, SLRNA transcription in vitro, and parasite viability. These functional attributes suggest that the factor represents TFIIF although the amino acid sequences are too divergent to firmly make this conclusion. This work strongly indicates that early-diverged trypanosomes have orthologues of each and every general transcription factor, requiring them for the synthesis of SL RNA. PMID- 29186513 TI - Projected impact of future climate on water-stress patterns across the Australian wheatbelt. AB - Drought frequently limits Australian wheat production, and the expected future increase in temperatures and rainfall variability will further challenge productivity. A modelling approach captured plant*environment*management interactions to simulate water-stress patterns experienced by wheat crops at representative locations across the Australian wheatbelt for 33 climate model projections, considering the 'business as usual' emission scenario RCP8.5. The results indicate that projections of future water-stress patterns are region specific. Significant variations in projected impacts were found across climate models, providing local ranges of uncertainty to consider in planning efforts. Most climate models projected an increase in the frequency of severe water-stress conditions in the Western area, the largest producing region, and fewer severe water stresses in other regions. Where found, reductions in water-stress conditions were largely due to shorter crop cycles (a result of warmer temperatures), increased water use efficiency (resulting from increased CO2 levels), and, in some cases, increased local rainfall. Overall, simulations indicate that all areas of the Australian wheatbelt will continue to experience severe water-stress conditions (43.9, 42.6, and 40.2% for 2030, 2050, and 2070 compared with 42.8% for 1990). Given projected frequencies of severe water stress and warmer conditions, efforts towards maintaining or improving yields are essential. PMID- 29186512 TI - DOFT and DOFTIP1 affect reproductive development in the orchid Dendrobium Chao Praya Smile. AB - FLOWERING LOCUS T (FT) in Arabidopsis encodes the florigen that moves from leaves to the shoot apical meristem to induce flowering, and this is partly mediated by FT-INTERACTING PROTEIN 1 (FTIP1). Although FT orthologs have been identified in some flowering plants, their endogenous roles in Orchidaceae, which is one of the largest families of flowering plants, are still largely unknown. In this study, we show that DOFT and DOFTIP1, the orchid orthologs of FT and FTIP1, respectively, play important roles in promoting flowering in the orchid Dendrobium Chao Praya Smile. Expression of DOFT and DOFTIP1 increases in whole plantlets during the transition from vegetative to reproductive development. Both transcripts are present in significant levels in reproductive organs, including inflorescence apices, stems, floral buds, and open flowers. Through successful generation of transgenic orchids, we have revealed that overexpression or down regulation of DOFT accelerates or delays flowering, respectively, while alteration of DOFT expression also greatly affects pseudobulb formation and flower development. In common with their counterparts in Arabidopsis and rice, DOFTIP1 interacts with DOFT and affects flowering time in orchids. Our results suggest that while DOFT and DOFTIP1 play evolutionarily conserved roles in promoting flowering, DOFT may have evolved with hitherto unknown functions pertaining to the regulation of storage organs and flower development in the Orchidaceae family. PMID- 29186514 TI - Permissive zones for the centromere-binding protein ParB on the Caulobacter crescentus chromosome. AB - Proper chromosome segregation is essential in all living organisms. In Caulobacter crescentus, the ParA-ParB-parS system is required for proper chromosome segregation and cell viability. The bacterial centromere-like parS DNA locus is the first to be segregated following chromosome replication. parS is bound by ParB protein, which in turn interacts with ParA to partition the ParB parS nucleoprotein complex to each daughter cell. Here, we investigated the genome-wide distribution of ParB on the Caulobacter chromosome using a combination of in vivo chromatin immunoprecipitation (ChIP-seq) and in vitro DNA affinity purification with deep sequencing (IDAP-seq). We confirmed two previously identified parS sites and discovered at least three more sites that cluster ~8 kb from the origin of replication. We showed that Caulobacter ParB nucleates at parS sites and associates non-specifically with ~10 kb flanking DNA to form a high-order nucleoprotein complex on the left chromosomal arm. Lastly, using transposon mutagenesis coupled with deep sequencing (Tn-seq), we identified a ~500 kb region surrounding the native parS cluster that is tolerable to the insertion of a second parS cluster without severely affecting cell viability. Our results demonstrate that the genomic distribution of parS sites is highly restricted and is crucial for chromosome segregation in Caulobacter. PMID- 29186517 TI - Renal replacement therapy intensity for acute kidney injury and recovery to dialysis independence: a systematic review and individual patient data meta analysis. AB - Background: There is no consensus whether higher intensity dose renal replacement therapy (RRT) compared with standard intensity RRT has survival benefit and achieves better renal recovery in acute kidney injury (AKI). Methods: In an individual patient data meta-analysis, we merged individual patient data from randomized controlled trials (RCTs) comparing high with standard intensity RRT in intensive care unit patients with severe AKI. The primary outcome was all-cause mortality. The secondary outcome was renal recovery assessed as the proportion of patients who were RRT dependent at key trial endpoints and by time to the end of RRT dependence. Results: Of the eight prospective RCTs assessing different RRT intensities, seven contributed individual patient data (n = 3682) to the analysis. Mortality was similar between the two groups at 28 days [769/1884 (40.8%) and 744/1798 (41.4%), respectively; P = 0.40] after randomization. However, more participants assigned to higher intensity therapy remained RRT dependent at the most common key study point of 28 days [e.g. 292/983 (29.7%) versus 235/943 (24.9%); relative risk 1.15 (95% confidence interval 1.00-1.33); P = 0.05]. Time to cessation of RRT through 28 days was longer in patients receiving higher intensity RRT (log-rank test P = 0.02) and when continuous renal replacement therapy was used as the initial modality of RRT (log-rank test P = 0.03). Conclusions: In severe AKI patients, higher intensity RRT does not affect mortality but appears to delay renal recovery.

PMID- 29186516 TI - Transgenic Bt Corn, Soil Insecticide, and Insecticidal Seed Treatment Effects on Corn Rootworm (Coleoptera: Chrysomelidae) Beetle Emergence, Larval Feeding Injury, and Corn Yield in North Dakota. AB - Northern, Diabrotica barberi Smith & Lawrence (Coleoptera: Chrysomelidae), and western, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), corn rootworms are economic pests of corn, Zea mays L. in North America. We measured the impacts of corn hybrids incorporated with Cry3Bb1, Cry34/35Ab1, and pyramided (Cry3Bb1 + Cry34/35Ab1) Bacillus thuringiensis Berliner (Bt) proteins, tefluthrin soil insecticide, and clothianidin insecticidal seed treatment on beetle emergence, larval feeding injury, and corn yield at five locations from 2013 to 2015 in eastern North Dakota. In most cases, emergence was significantly lower in Bt-protected corn than in non-Bt corn hybrids. Exceptions included Wyndmere, ND (2013), where D. barberi emergence from Cry34/35Ab1 plots was not different from that in the non-Bt hybrid, and Arthur, ND (2013), where D. v. virgifera emergence from Cry3Bb1 plots did not differ from that in the non-Bt hybrid. Bt hybrids generally produced increased grain yield compared with non-Bt corn where rootworm densities were high, and larval root-feeding injury was consistently lower in Bt protected plots than in non-Bt corn. The lowest overall feeding injury and emergence levels occurred in plots planted with the Cry3Bb1 + Cry34/35Ab1 hybrid. Time to 50% cumulative emergence of both species was 5-7 d later in Bt-protected than in non-Bt hybrids. Tefluthrin and clothianidin were mostly inconsequential in relation to beetle emergence and larval root injury. Our findings could suggest that some North Dakota populations could be in early stages of increased tolerance to some Bt toxins; however, Bt corn hybrids currently provide effective protection against rootworm injury in eastern North Dakota. PMID- 29186519 TI - Effects of Fatty Acid and Geraniol Repellent-Oil Mixtures Applied to Cattle on Blood Feeding and Reproductive Parameters in Field Populations of Haematobia irritans (Diptera: Muscidae). AB - California pastured cattle were treated with 250 ml of a 15% mixture of fatty acids (C8-C9-C10) or 125 ml of 2% geraniol in a mineral oil carrier to assess impacts on horn flies, Haematobia irritans (L.) (Diptera: Muscidae) over two summers. Horn flies were netted from cattle every 3-4 d for 2 wk before treatment, 2 wk during treatment (four treatments, with flies collected before each treatment), and 2 wk after treatments ceased. Blood meal weights were estimated by hemoglobin assay of excised abdomens. Other females were dissected to determine the number of active ovarioles and the stage of primary follicle development. Depending on year and herd, pretreatment males contained an average of 0.6-1.0 mg of blood, while females contained 1.7-2.7 mg. Pretreatment egg development (least developed oocytes were stage 1 and fully developed eggs were stage 5) averaged 3.7-4.3, and number of active ovarioles averaged 18.1 to 19.6/female. During treatment periods, significant reductions in blood weight were noted for females, but usually not for males, and females also often exhibited reduced mean oocyte stage and number of active ovarioles. Peaks in proportions of young nulliparous females (oocyte stages 1 or 2) were seen during some repellent application periods. This suggested older females had been killed or driven off from the local population by the treatments, and flies on cattle included more young flies that likely were recent arrivals. The repellent-oil mixture thus impacted blood feeding, reproductive fitness, and probably age structure in the field. PMID- 29186520 TI - Intrapuparial Development of Sarconesia Chlorogaster (Diptera: Calliphoridae) for Postmortem Interval Estimation (PMI). AB - Sarconesia chlorogaster (Wiedemann) (Diptera: Calliphoridae) is an endemic blow fly species of forensic importance in South America, and whose duration of pupal development is about 70% of the total immature development time. Therefore, morphological changes during this stage, if refined, may provide greater accuracy and reliability in the calculation of minimum postmortem interval. Considering the importance of this species, the main objective of this work was to identify and describe temporal intrapuparial morphological changes of S. chlorogaster. The development of S. chlorogaster reared on an artificial diet and at two constant temperatures (20 and 25oC) was monitored. Every 8 h until the end of the pupal stage, 10 pupae were killed, fixed, and had their external morphology described and photographed. Of the 29 morphological characteristics described, 13 are potentially informative for estimating the age of S. chlorogaster. In general, body shape (presence or absence of tagmatization), general coloration, visible presence of the mouth hook (portion of the mandible), thoracic appendages, change in eye color, and bristle formation are the most useful characteristics for determining specific age. The results presented here make it possible to estimate the postmortem interval of a corpse using intrapuparial morphological characters, expanding one's ability to estimate postmortem interval. PMID- 29186518 TI - Diversity-generating retroelements: natural variation, classification and evolution inferred from a large-scale genomic survey. AB - Diversity-generating retroelements (DGRs) are novel genetic elements that use reverse transcription to generate vast numbers of sequence variants in specific target genes. Here, we present a detailed comparative bioinformatic analysis that depicts the landscape of DGR sequences in nature as represented by data in GenBank. Over 350 unique DGRs are identified, which together form a curated reference set of putatively functional DGRs. We classify target genes, variable repeats and DGR cassette architectures, and identify two new accessory genes. The great variability of target genes implies roles of DGRs in many undiscovered biological processes. There is much evidence for horizontal transfers of DGRs, and we identify lineages of DGRs that appear to have specialized properties. Because GenBank contains data from only 10% of described species, the compilation may not be wholly representative of DGRs present in nature. Indeed, many DGR subtypes are present only once in the set and DGRs of the candidate phylum radiation bacteria, and Diapherotrites, Parvarchaeota, Aenigmarchaeota, Nanoarchaeota, Nanohaloarchaea archaea, are exceptionally diverse in sequence, with little information available about functions of their target genes. Nonetheless, this study provides a detailed framework for classifying and studying DGRs as they are uncovered and studied in the future. PMID- 29186515 TI - Assessment of moderate coffee consumption and risk of epithelial ovarian cancer: a Mendelian randomization study. AB - Background: Coffee consumption has been shown to be associated with various health outcomes in observational studies. However, evidence for its association with epithelial ovarian cancer (EOC) is inconsistent and it is unclear whether these associations are causal. Methods: We used single nucleotide polymorphisms associated with (i) coffee and (ii) caffeine consumption to perform Mendelian randomization (MR) on EOC risk. We conducted a two-sample MR using genetic data on 44 062 individuals of European ancestry from the Ovarian Cancer Association Consortium (OCAC), and combined instrumental variable estimates using a Wald-type ratio estimator. Results: For all EOC cases, the causal odds ratio (COR) for genetically predicted consumption of one additional cup of coffee per day was 0.92 [95% confidence interval (CI): 0.79, 1.06]. The COR was 0.90 (95% CI: 0.73, 1.10) for high-grade serous EOC. The COR for genetically predicted consumption of an additional 80 mg caffeine was 1.01 (95% CI: 0.92, 1.11) for all EOC cases and 0.90 (95% CI: 0.73, 1.10) for high-grade serous cases. Conclusions: We found no evidence indicative of a strong association between EOC risk and genetically predicted coffee or caffeine levels. However, our estimates were not statistically inconsistent with earlier observational studies and we were unable to rule out small protective associations. PMID- 29186521 TI - Oxidation of Selected Phenothiazine Drugs During Sample Preparation: Effects of Varying Extraction Conditions on the Extent of Oxidation. AB - Characterization of degradation products formed from selected phenothiazine drugs during standard solid-phase extraction (SPE) approaches is described. An analytical method for promethazine (PMZ), chlorpromazine (CPZ) and their respective N-desmethyl and sulfoxide metabolites in biological samples (bone tissue extract and blood) by ultra performance liquid chromatography-photodiode array detection, using mixed-mode SPE for basic drugs was developed. When ethyl acetate:isopropanol:ammonium hydroxide (80:17:3) was used as the elution solvent during method development, extraneous peaks were observed that were absent in the negative controls. Analysis of extracts of PMZ and CPZ individually showed extraneous peaks, including peaks with retention time and UV spectra suggesting the formation of the sulfoxide metabolites, amongst others. Analytes were then extracted individually and analyzed by ultra performance liquid chromatography quadrupole time-of-flight mass spectrometry. The results confirmed the oxidation of PMZ to its sulfoxide and N-oxide metabolites and oxidation of CPZ to its sulfoxide metabolite. Oxidation was also observed in analysis of whole blood, and thus was not specific to bone tissue extract. To determine if extraction with minimal oxidation was possible, extractions using SPE with a different elution solvent system (dichloromethane:isopropanol:ammonium hydroxide) and filtration/pass through extraction (FPTE) with and without evaporation were evaluated. The results demonstrated that the sample preparation method highly influenced the extent of oxidation. FPTE without an evaporation step was the only method that did not measurably induce analyte oxidation. PMID- 29186522 TI - Prevalence and patterns of cognitive impairment in adult hemodialysis patients: the COGNITIVE-HD study. AB - Background: Mounting evidence indicates an increased risk of cognitive impairment in adults with end-stage kidney disease on dialysis, but the extent and pattern of deficits across the spectrum of cognitive domains are uncertain. Methods: We conducted a cross-sectional study of 676 adult hemodialysis patients from 20 centers in Italy, aiming to evaluate the prevalence and patterns of cognitive impairment across five domains of learning and memory, complex attention, executive function, language and perceptual-motor function. We assessed cognitive function using a neuropsychological battery of 10 tests and calculated test and domain z-scores using population norms (age or age/education). We defined cognitive impairment as a z-score <= -1.5. Results: Participants' median age was 70.9 years (range 21.6-94.1) and 262 (38.8%) were women. Proportions of impairment on each domain were as follows: perceptual-motor function 31.5% (150/476), language 41.2% (273/662), executive function 41.7% (281/674), learning and memory 42.2% (269/638), complex attention 48.8% (329/674). Among 474 participants with data for all domains, only 28.9% (n = 137) were not impaired on any domain, with 25.9% impaired on a single domain (n = 123), 17.3% on two (n = 82), 13.9% on three (n = 66), 9.1% on four (n = 43) and 4.9% (n = 23) on all five. Across patients, patterns of impairment combinations were diverse. Conclusions: In conclusion, cognitive impairment is extremely common in hemodialysis patients, across numerous domains, and patients often experience multiple deficits simultaneously. Clinical care should be tailored to meet the needs of patients with different types of cognitive impairment and future research should focus on identifying risk factors for cognitive decline. PMID- 29186523 TI - DNA-based mutation assay GPMA (genome profiling-based mutation assay): reproducibility, parts-per-billion scale sensitivity, and introduction of a mammalian-cell-based approach. AB - Genome profiling-based mutation assay (GPMA) is, to date, the only DNA sequence based mutation assay that directly measures DNA alterations induced by mutagens. Here, the all-important congruence of mutagen assignment between DNA-based GPMA and the phenotype-based Ames test (the gold standard of mutagen assays) was confirmed qualitatively and semi-quantitatively by means of 94 chemical species (including previously examined 64). The high sensitivity (on the order of 10 ppb) and reproducibility of GPMA were also corroborated by the match between virtually independent experiments conducted in the distant past (10 years ago) and recently. Meanwhile, a standard experimental framework was established: the conditions of 100 parts per billion (ppb) concentration of a chemical and 15 generation culture of Escherichia coli. Moreover, a mammalian cell line (NIH 3T3) was shown to be suitable as a tester organism for the GPMA approach. Preliminary experimental results suggested that this approach can provide a qualitatively equivalent and quantitatively different mutagen assay results relative to the bacteria-based GPMA (renamed as bGPMA). This finding confirmed the effectiveness of the GPMA approach and indicates that mGPMA is a promising way to detect mammalian-cell mutagens. PMID- 29186524 TI - Inhibition of DNA replication by an anti-PCNA aptamer/PCNA complex. AB - Proliferating cell nuclear antigen (PCNA) is a multifunctional protein present in the nuclei of eukaryotic cells that plays an important role as a component of the DNA replication machinery, as well as DNA repair systems. PCNA was recently proposed as a potential non-oncogenic target for anti-cancer therapy. In this study, using the Systematic Evolution of Ligands by EXponential enrichment (SELEX) method, we developed a short DNA aptamer that binds human PCNA. In the presence of PCNA, the anti-PCNA aptamer inhibited the activity of human DNA polymerase delta and epsilon at nM concentrations. Moreover, PCNA protected the anti-PCNA aptamer against the exonucleolytic activity of these DNA polymerases. Investigation of the mechanism of anti-PCNA aptamer-dependent inhibition of DNA replication revealed that the aptamer did not block formation, but was a component of PCNA/DNA polymerase delta or epsilon complexes. Additionally, the anti-PCNA aptamer competed with the primer-template DNA for binding to the PCNA/DNA polymerase delta or epsilon complex. Based on the observations, a model of anti-PCNA aptamer/PCNA complex-dependent inhibition of DNA replication was proposed. PMID- 29186525 TI - Hot lungs, bitter cherry: intravascular lymphoma.

AB - In Montgomery v Lanarkshire Health Board [2015] UKSC 11 the Supreme Court redefined the standard of disclosure in informed consent to medical treatment, rejecting the application of the doctor-focused Bolam standard in favour of one focused on what was significant to patients. In Grimstone v Epsom and St Helier University Hospitals NHS Trust [2015] EWHC 3756 (QB), despite acknowledging a new standard now applied, McGowan J nevertheless used the Bolam test to determine liability for non-disclosure. This illustrates ongoing judicial deference to the medical profession and this case commentary explores that decision and its implications. PMID- 29186528 TI - Conformational dynamism for DNA interaction in the Salmonella RcsB response regulator. AB - The RcsCDB phosphorelay system controls an extremely large regulon in Enterobacteriaceae that involves processes such as biofilm formation, flagella production, synthesis of extracellular capsules and cell division. Therefore, fine-tuning of this system is essential for virulence in pathogenic microorganisms of this group. The final master effector of the RcsCDB system is the response regulator (RR) RcsB, which activates or represses multiple genes by binding to different promoter regions. This regulatory activity of RcsB can be done alone or in combination with additional transcriptional factors in phosphorylated or dephosphorylated states. The capacity of RcsB to interact with multiple promoters and partners, either dephosphorylated or phosphorylated, suggests an extremely conformational dynamism for this RR. To shed light on the activation mechanism of RcsB and its implication on promoter recognition, we solved the crystal structure of full-length RcsB from Salmonella enterica serovar Typhimurium in the presence and absence of a phosphomimetic molecule BeF3-. These two novel structures have guided an extensive site-directed mutagenesis study at the structural and functional level that confirms RcsB conformational plasticity and dynamism. Our data allowed us to propose a beta5-T switch mechanism where phosphorylation is coupled to alternative DNA binding ways and which highlights the conformational dynamism of RcsB to be so pleiotropic. PMID- 29186529 TI - Protection of the Human Gut Microbiome From Antibiotics. AB - Background: Antibiotics are life-saving drugs but severely affect the gut microbiome with short-term consequences including diarrhea and selection of antibiotic-resistant bacteria. Long-term links to allergy and obesity are also suggested. We devised a product, DAV132, and previously showed its ability to deliver a powerful adsorbent, activated charcoal, in the late ileum of human volunteers. Methods: We performed a randomized controlled trial in 28 human volunteers treated with a 5-day clinical regimen of the fluoroquinolone antibiotic moxifloxacin in 2 parallel groups, with or without DAV132 coadministration. Two control goups of 8 volunteers each receiving DAV132 alone, or a nonactive substitute, were added. Results: The coadministration of DAV132 decreased free moxifloxacin fecal concentrations by 99%, while plasmatic levels were unaffected. Shotgun quantitative metagenomics showed that the richness and composition of the intestinal microbiota were largely preserved in subjects co treated with DAV132 in addition to moxifloxacin. No adverse effect was observed. In addition, DAV132 efficiently adsorbed a wide range of clinically relevant antibiotics ex vivo. Conclusions: DAV132 was highly effective to protect the gut microbiome of moxifloxacin-treated healthy volunteers and may constitute a clinical breakthrough by preventing adverse health consequences of a wide range of antibiotic treatments.

AB - While circumventing legislative controls, synthetic piperazines are encountered as "legal" alternatives to ecstasy. Unforeseeable challenges may delay quantitative analysis of these compounds in biological fluids. Enzymatic reactions, matrix interferences and limited knowledge of analyte stability further complicate interpretation of calculated concentrations. The objective of this study was to investigate the stability of synthetic piperazines in human blood under various storage conditions over time. All samples were prepared by spiking certified reference standards (Cayman Chemical, MI, U.S.A.) of eight synthetic piperazine into certified drug-free human whole blood (UTAK Laboratories, Inc., CA, U.S.A.) independently at 1000 ng/mL as well as mixtures containing all tested piperazines in this study. Samples were stored at room temperature (~20 degrees C), 4 degrees C and -20 degrees C for 1, 3, 6, 9 and 12 months in dark sealed containers. Solid phase extraction (SPE) was performed using mixed-mode copolymeric cartridges (Clean Screen(r), UCT Inc., PA, U.S.A.). Analytes were assessed on their degrees of degradation using a Shimadzu Ultra Fast Liquid Chromatograph with SCIEX 4000 Q-Trap Electrospray Ionization Tandem Mass Spectrometer (UFLC-ESI-MS/MS) in positive ionization mode. Of the two categories, benzyl piperazines were more stable than phenyl piperazines under all storage conditions, in which 1-(4-methylbenzyl)-piperazine (MBZP) had more than 70% (769-1,047 ng/mL) remaining after 12 months. 1-(4-methoxyphenyl)-piperazine (MeOPP) was not detected under room and refrigerated temperatures after 6 months and was the least stable. Matrix interferences and drug-drug interaction were observed. Storing samples at room temperature should be avoided due to detrimental impacts on stability of piperazine compounds. For backlog situations, case samples suspected to contain synthetic piperazines should be kept frozen or refrigerated even for time periods as short as 30 days for optimal result. Phenyl piperazines stored for more than 6 months showed analyte degradation and loss of parent compounds after extended storage regardless of storage conditions. PMID- 29186531 TI - A Novel NAC-Type Transcription Factor, NAC87, from Oilseed Rape Modulates Reactive Oxygen Species Accumulation and Cell Death. AB - Reactive oxygen species (ROS) are thought to play a dual role in plants by functioning as signaling molecules and toxic by-products of aerobic metabolism. The hypersensitive response (HR) is a typical feature of immune responses in plants and also a type of programmed cell death (PCD). How these two processes are regulated in oilseed rape (Brassica napus L.) at the transcriptional level remains largely unknown. In this study, we report that an oilseed rape (Brassica napus L.) NAM-ATAF-CUC (NAC)-type transcription factor NAC87 modulates ROS and cell death accompanied by typical changes at the morphological and cellular levels. The BnaNAC87 gene was induced by multiple stress and hormone treatments and was highly expressed in senescent leaves by quantitative reverse transcription-PCR (qRT-PCR). BnaNAC87 is located in nuclei and has transcriptional activation activity. Expression of BnaNAC87 promoted significant ROS production, cell death as well as death of protoplasts, as indicated by histological staining. In addition, putative downstream target genes of NAC87 were identified through both qRT-PCR and dual luciferase reporter assays. We found that genes implicated in ROS generation (RbohB), cell death (VPE1a, ZEN1), leaf senescence (WRKY6, ZAT12) and defense (PR2, PR5 and HIN1) were significantly induced. Through an electrophoretic mobility shift assay (EMSA), we confirmed that BnaNAC87 directly binds to the NACRS-containing promoter fragments of ZEN1, ZAT12, HIN1 and PR5 genes. From these results, we conclude that oilseed rape NAC87 is a novel NAC transcription factor that acts as a positive regulator of ROS metabolism and cell death. PMID- 29186533 TI - Surgical treatment for isolated mitral valve endocarditis: a 16-year single centre experience. AB - OBJECTIVES: Despite progress in management, mitral valve endocarditis (MVE) is still a life-threatening disease. We report our experience in surgical treatment of infective isolated MVE. METHODS: A total of 140 operations in 128 patients for MVE performed between January 2000 and December 2015 were included in a retrospective study. There were 109 (78%) operations for native and 31 (22%) operations for prosthetic valve endocarditis. Preoperative and postoperative characteristics and mortality of patients were registered. Cox regression identified factors associated with mortality. Mean follow-up period was 68 months (range 1-168 months) and 100% complete. RESULTS: There were 13 deaths within 30 days after the 140 operations (9%). Severe perioperative complications occurred in 59 (42%) operations. Overall cumulative survival was 73% +/- 4 at 5 years and 62 +/- 5% at 10 years after the first operation. Age, diabetes, EuroSCORE II and perivalvular abscess were independent predictors for long-term mortality. Valve repair was performed in 76 (54%) operations and replacement in 64 (46%) operations. Thirty-day mortality for repair was 1%, and 5-year and 10-year cumulative survival was 86 +/- 4% and 77 +/- 6%, respectively. In the replacement group the 30-day mortality was 19% and cumulative survival at 5 years and 10 years was 55 +/- 7% and 41 +/- 8%, respectively. Postoperative complications occurred in 21% and 67%, respectively, after operations for repair and replacement. Ten (8%) patients had 12 reoperations for recurrent endocarditis. CONCLUSIONS: MVE requiring surgical treatment is a challenging disease with high hospital mortality after valve replacement. Mitral valve repair can be performed in suitable endocarditis patients with excellent results. Age, diabetes and EuroSCORE were independently associated with mortality in a multivariable model. PMID- 29186532 TI - Loss of offspring Peg3 reduces neonatal ultrasonic vocalizations and increases maternal anxiety in wild-type mothers. AB - Depression and anxiety are the most common mental health conditions during pregnancy and can impair the normal development of mother-infant interactions. These adversities are associated with low birth weight and increased risk of behavioural disorders in children. We recently reported reduced expression of the imprinted gene PATERNALLY EXPRESSED GENE 3 (PEG3) in placenta of human infants born to depressed mothers. Expression of Peg3 in the brain has previously been linked maternal behaviour in rodents, at least in some studies, with mutant dams neglecting their pups. However, in our human study decreased expression was in the placenta derived from the fetus. Here, we examined maternal behaviour in response to reduced expression of Peg3 in the feto-placental unit. Prenatally we found novelty reactivity was altered in wild-type females carrying litters with a null mutation in Peg3. This behavioural alteration was short-lived and there were no significant differences the transcriptomes of either the maternal hypothalamus or hippocampus at E16.5. In contrast, while maternal gross maternal care was intact postnatally, the exposed dams were significantly slower to retrieve their pups and displayed a marked increase in anxiety. We also observed a significant reduction in the isolation-induced ultrasonic vocalizations (USVs) emitted by mutant pups separated from their mothers. USVs are a form of communication known to elicit maternal care suggesting Peg3 mutant pups drive the deficit in maternal behaviour. These data support the hypothesis that reduced placental PEG3 in human pregnancies occurs as a consequence of prenatal depression but leaves scope for feto-placental Peg3 dosage, during gestation, influencing aspects of maternal behaviour. PMID- 29186534 TI - Temperature and Tissue Type Impact Development of Lucilia cuprina (Diptera: Calliphoridae) in Sri Lanka. AB - Lucilia cuprina (Wiedemann; Diptera: Calliphoridae) is a facultative ecto parasitic fly, distributed throughout the temperate and subtropical regions of the world. This blow fly species is of medical, veterinary, and forensic importance due to it being used in maggot debridement therapy (MDT), a causative agent of myiasis, and a decomposer of vertebrate carrion. The current study examined the combined effects of temperature and tissue type on the development of L. cuprina. Specimens were reared on three tissue types; swine muscle, swine liver, and bovine muscle at 20 degrees C, 25 degrees C, 27 degrees C, and 38 degrees C. The optimum condition for L. cuprina development was for immatures reared on bovine muscle (287.4 h) followed by those reared on swine muscle (288.0 h) and swine liver (288.4 h) at 27 degrees C. The minimum temperature threshold of L. cuprina was deduced to be 14 degrees C. No significant differences in larval width and length over time were determined for the tissue type. PMID- 29186535 TI - Analysis of last statements prior to execution: methods, themes and future directions. AB - Worldwide, over 1000 people were executed in 2016 and over 3000 sentenced to death. Death row prisoners have high rates of mental illness, often combined with neurological impairment. Prolonged confinement has further negative effects on psychological function. There is a growing literature examining key themes and psychological constructs in death row prisoners immediately prior to execution. To date, this literature centres largely but not exclusively on last statements from death row in Texas, owing to ease of availability. The most common themes in last statements are love, spirituality and apology or regret. The most common psychological constructs are 'identification-egression' (e.g. attachment to a lost person or ideal, such as freedom), unbearable psychological pain and rejection-aggression. This is still a relatively new area of research and new techniques, such as computerised quantitative text analysis, are likely to complement rather than replace more traditional forms of thematic and textual analysis. For the future, it is essential that studies in this field continue to specify precisely, which last statements they use, so that overlap can be identified, and that more countries are studied (if possible). It would also be useful to expand the research frame to relate the content of last statements to additional variables relating to prisoners' offences, physical health, mental health, family structure and broader circumstances. Finally, ethical issues require continued consideration in this complex, fascinating, growing field. PMID- 29186536 TI - Comparison and Mechanism of the UV-Resistant Mosquitocidal Bt Mutant LLP29-M19. AB - Bacillus thuringiensis (Bt) is one of the most widely used and studied biopesticides. However, it is vulnerable to the influence of ultraviolet (UV) radiation, causing shorter persistence under field conditions. To obtain a high active and effective Bt new product, the main objective of this study is to obtain a highly UV-resistant Bt mutant from the mosquitocidal Bt LLP29 through UV exposure. After 19 rounds of UV exposure, a Bt mutant named LLP29-M19 was obtained, showing resistance to UV radiation for up to 67 min. The mosquitocidal fatality rate of LLP29-M19 was 95%, which was slightly higher than that of LLP29 (90%). Comparative characterization showed that there were no substantial differences in morphology between LLP29-M19 and the original strain, LLP29. However, some changes were detected in physiological and biochemical characteristic reactions, including fructose, glucose, and xylose metabolism. Furthermore, although both LLP29-M19 and LLP29 showed negative zeta potentials, the surface charge of LLP29 was -28.1 mV and that of LLP29-M19 was -42.8 mV. The size distribution of LLP29-M19 was also slightly larger than that of LLP29. Fourier transform infrared analysis indicated that amide functional groups might be involved in the resistance mechanism of LLP29-M19. Quantitative analysis using inductive coupled plasma emission spectrometry showed that some elements increased greatly in LLP29-M19, such as K. All of these results will be highly valuable for better understanding the mechanism of Bt resistance. Explanations regarding the resistance mechanism of this novel Bt mutant may lead to the development of new biopesticides with high mosquitocidal activity and persistence. PMID- 29186537 TI - Fabry disease under enzyme replacement therapy-new insights in efficacy of different dosages. AB - Background: Fabry patients on reduced dose of agalsidase-beta or after switch to agalsidase-alfa show a decline in estimated glomerular filtration rate (eGFR) and an increase of the Mainz Severity Score Index. Methods: In this prospective observational study, we assessed end-organ damage and clinical symptoms in 112 patients who had received agalsidase-beta (1.0 mg/kg) for >1 year, who were (i) non-randomly assigned to continue this treatment regime (regular-dose group, n = 37); (ii) received a reduced dose of agalsidase-beta and subsequent switch to agalsidase-alfa (0.2 mg/kg) or a direct switch to 0.2 mg/kg agalsidase-alfa (switch group, n = 38); or (iii) were re-switched to agalsidase-beta after receiving agalsidase-alfa for at least 12 months (re-switch group, n = 37) with a median follow-up of 53 (38-57) months. Results: eGFR of patients in the regular dose group remained stable. Patients in the switch group showed an annual eGFR loss of - 4.6 +/- 9.1 mL/min/1.73 m2 (P < 0.05). Patients in the re-switch group also had an eGFR loss of - 2.2 +/- 4.4 mL/min/1.73 m2 after re-switch to agalsidase-beta, but to a lower degree compared with the switch group (P < 0.05). Patients in the re-switch group suffered less frequently from diarrhoea (relative risk 0.42; 95% confidence interval 0.19-0.93; P = 0.02). Lyso-Gb3 remained stable in the switch (P = 0.97) and the regular-dose (P = 0.48) groups, but decreased in the re-switch group after change of the therapy regimen (P < 0.05). Conclusions: After switch to agalsidase-alfa, Fabry patients experienced a continuous decline in eGFR, while this decline was attenuated in patients who were re-switched to agalsidase-beta. Decreasing lyso-Gb3 levels may indicate a better treatment response in the latter group. PMID- 29186538 TI - The potential for dual pathology in temporal arteritis. PMID- 29186539 TI - Reconstitution of the CstF complex unveils a regulatory role for CstF-50 in recognition of 3'-end processing signals. AB - Cleavage stimulation factor (CstF) is a highly conserved protein complex composed of three subunits that recognizes G/U-rich sequences downstream of the polyadenylation signal of eukaryotic mRNAs. While CstF has been identified over 25 years ago, the architecture and contribution of each subunit to RNA recognition have not been fully understood. In this study, we provide a structural basis for the recruitment of CstF-50 to CstF via interaction with CstF 77 and establish that the hexameric assembly of CstF creates a high affinity platform to target various G/U-rich sequences. We further demonstrate that CstF 77 boosts the affinity of the CstF-64 RRM to the RNA targets and CstF-50 fine tunes the ability of the complex to recognize G/U sequences of certain lengths and content.

AB - The pine sawyer beetle, Monochamus alternatus Hope (Coleoptera: Cerambycidae) is a serious insect pest of pine trees by vectoring the pine wood nematode, Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle (Nematoda: Aphelenchoididae). Field studies were carried out during 2013-2015 in Guangdong (China) to evaluate the effectiveness of commercial attractants, effect of trap placement for monitoring M. alternatus, and temporal patterns of trap catch. Four commercial attractants, three trap placements (0, 1.5, and 3 m above ground) and different trapping distances (50, 200, 400, 600, and 900 m) from forest edge were evaluated for monitoring M. alternatus. Traps baited with a mixture of monochamol and plant volatiles captured significantly more beetles than traps baited with monochamol alone or plant volatiles alone. Traps set up at 1.5 m above the ground captured significantly more M. alternatus than those at 0 m and 3 m height. Based on 2,687 beetles trapped from two locations in 2013 and 2014, the female:male ratio was 2.9-4.1:1. The beetles' natural dispersal distance was approximately 100 m based on traps set at different distances from edge of the forest. Continuous monitoring over 38-wk period indicates the peak of adult M. alternatus emergence was between May and June within a year. PMID- 29186541 TI - Neuroendocrine and neurophysiological effects of interleukin 6 in rheumatoid arthritis. AB - RA is a chronic, systemic, autoimmune disease characterized by inflammation and degradation of the joints, causing significant negative impact on quality of life. In addition to joint disease, symptoms and co-morbidities associated with RA-namely pain, fatigue and mood disorders-are often as debilitating as the disease itself. The pro-inflammatory cytokine IL-6 plays a critical role in RA associated pathology. However, a greater understanding of the translational effects of IL-6 outside of the immune system is needed. This review discusses our current understanding of emerging aspects of IL-6 in RA-associated pain, fatigue and mood disorders such as depression and anxiety. This review also describes the clinical effects of IL-6 inhibition on these symptoms and co-morbidities in patients with RA.

AB - The Asian tiger mosquito, Aedes albopictus (Skuse) (Diptera: Culicidae), is an invasive species and a vector of numerous human pathogens, including chikungunya, dengue, yellow fever, and Zika viruses. This mosquito had been reported from 36 geographic locations in Mexico by 2005, increasing to 101 locations by 2010 and 501 locations (spanning 16 states) by 2016. Here we modeled the occupied niche for Ae. albopictus in Mexico to characterize the environmental conditions related to its presence, and to generate updated environmental suitability maps. The predictors with the greatest contribution to characterizing the occupied niche for Ae. albopictus were NDVI and annual mean temperature. We also estimated the environmental suitability for Ae. albopictus in regions of the country where it has not been documented yet, by means of: 1) transferring its occupied niche model to these regions and 2) modeling its fundamental niche using global data. Our models will help vector control and public health institutions to identify areas where Ae. albopictus has not yet been recorded but where it may be present. We emphasize that most of Mexico has environmental conditions that potentially allow the survival of Ae. albopictus, which underscores the need for systematic mosquito monitoring in all states of the country.

AB - Single cell whole-genome sequencing (scWGS) is providing novel insights into the nature of genetic heterogeneity in normal and diseased cells. However, the whole genome amplification process required for scWGS introduces biases into the resulting sequencing that can confound downstream analysis. Here, we present a statistical method, with an accompanying package PaSD-qc (Power Spectral Density qc), that evaluates the properties and quality of single cell libraries. It uses a modified power spectral density to assess amplification uniformity, amplicon size distribution, autocovariance and inter-sample consistency as well as to identify chromosomes with aberrant read-density profiles due either to copy alterations or poor amplification. These metrics provide a standard way to compare the quality of single cell samples as well as yield information necessary to improve variant calling strategies. We demonstrate the usefulness of this tool in comparing the properties of scWGS protocols, identifying potential chromosomal copy number variation, determining chromosomal and subchromosomal regions of poor amplification, and selecting high-quality libraries from low-coverage data for deep sequencing. The software is available free and open-source at https://github.com/parklab/PaSDqc. PMID- 29186546 TI - Automated lipid-rich plaque detection with short wavelength infra-red OCT system. AB - Aims: Vulnerable coronary plaque is characterized by a large lipid core. Although commercially-available optical coherence tomography (OCT) systems use near infrared light at 1300 nm wavelength, lipid shows characteristic absorption at 1700 nm. Therefore, we developed a novel, short wavelength infra-red, spectroscopic, spectral-domain OCT. The aim of the present study is to evaluate the accuracy of short wavelength (1700 nm) infra-red optical coherence tomography (SWIR-OCT) for identification of lipid tissue within coronary plaques. Methods and results: Twenty-three coronary arteries from 10 cadavers were imaged at physiological pressure with 2.7 Fr SWIR-OCT catheter. When a blood-free image was observed, the SWIR-OCT imaging core was withdrawn at a rate of 20 mm/s using an automatic pullback device. SWIR-OCT images were acquired at 94 frames/s and digitally archived. SWIR-OCT generated grey-scale cross sectional images and colour tissue maps of all of the plaque by using a lipid analysis algorithm. After SWIR-OCT imaging, the arteries were pressure-fixed, sliced by cryostat and stained with Oil Red O, and then corresponding histology was collected in matched images. Regions of interest, selected from histology, were 117 lipidic and 34 fibrotic/calcified regions. SWIR-OCT showed high sensitivity (89%) and specificity (92%) for identifying lipid tissue within coronary plaques. The positive predictive value and negative predictive value were 97% and 74%, respectively. Conclusion: SWIR-OCT accurately identified lipid tissue in coronary autopsy specimens. This new technique may hold promise for identifying histopathological features of coronary plaque at risk for rupture. PMID- 29186547 TI - Koilonychia in iron deficiency.

AB - Background: The pathophysiology of a paradoxical systolic blood pressure (SBP) rise during hemodialysis (HD) is not yet fully understood. Recent research indicated that 10% of chronic HD patients suffer from prolonged intradialytic hypoxemia. Since hypoxemia induces a sympathetic response we entertained the hypothesis that peridialytic SBP change is associated with arterial oxygen saturation (SaO2). Methods: We retrospectively analyzed intradialytic SaO2 and peridialytic SBP change in chronic HD patients with arteriovenous vascular access. Patients were followed for 6 months. We defined persistent intradialytic hypertension (piHTN) as average peridialytic SBP increase >=10 mmHg over 6 months. Linear mixed effects (LME) models were used to explore associations between peridialytic SBP change and intradialytic SaO2 in univariate and adjusted analyses. Results: We assessed 982 patients (29 872 HD treatments; 59% males; 53% whites). Pre-dialysis SBP was 146.7 +/- 26.5 mmHg and decreased on average by 10.1 +/- 24.5 mmHg. Fifty-three (5.7%) patients had piHTN. piHTN patients had lower intradialytic SaO2, body weight and interdialytic weight gain. LME models revealed that with every percentage point lower mean SaO2, the peridialytic SBP change increased by 0.46 mmHg (P < 0.001). This finding was corroborated in multivariate analyses. Conclusion: We observed an inverse relationship between intradialytic SaO2 and the blood pressure response to HD. These findings support the notion that hypoxemia activates mechanisms that partially blunt the intradialytic blood pressure decline, possibly by sympathetic activation and endothelin-1 secretion. To further explore that hypothesis, specifically designed prospective studies are required. PMID- 29186551 TI - The Johns Hopkins Atlas of Surgical Neuropathology (iPad Application). PMID- 29186550 TI - An objective neural signature of rapid perspective taking. AB - The frequency-tagging approach has generally been confined to study low-level sensory processes and always found related activation over the occipital region. Here for the first time, we investigated with it, high-level socio-cognitive functions, i.e. the processing of what other people are looking at which is referred to as level 1 visual perspective taking (VPT). Sixteen participants were presented with visual scenes alternating at 2.5 Hz which were depicting a person and an object in a room, while recording electrophysiological brain activity. The person orientation and object position changed at every stimulus but the person in the room always faced the object, except on every fifth stimulus. We found responses in the electroencephalography (EEG) spectrum exactly at the frequency corresponding to the presentation of the scenes where the person could not see the object, i.e. 0.5 Hz. While the 2.5 Hz stimulation rate response focused on typical medial occipital sites, the specific 0.5 Hz response was found mainly over a centro-parietal region. Besides a robust group effect, these responses were significant and quantifiable for most individual participants. Overall, these observations reveal a clear measure of level 1-VPT representation, highlighting the potential of EEG frequency-tagging to capture high-level socio cognitive functions in the brain.

PMID- 29186552 TI - Regulation of the epithelial barrier by post-translational modifications of tight junction membrane proteins. AB - Body and organ surfaces in multicellular organisms are covered with a sheet of epithelial cells. The tight junction (TJ) is an adhesive structure that seals the gap between epithelial cells and functions as a selective barrier to prevent the entry of antigens and pathogenic microbes from the extracellular environment. Several transmembrane proteins that constitute the TJ (claudin, occludin, tricellulin and angulin) have been identified. As over-expression of these proteins does not enlarge TJs or enhance epithelial barrier function, it remains unclear how TJ membrane proteins are regulated to modulate the amount of TJ and the strength of the epithelial barrier. In this review, we discuss the post translational modifications of TJ membrane proteins and their physiological significance from the viewpoint of the dynamic regulation of the epithelial barrier. PMID- 29186554 TI - Preclinical validation of a targeted next generation sequencing-based comprehensive chromosome screening methodology in human blastocysts. AB - STUDY QUESTION: Can a novel targeted next generation sequencing (tNGS) platform accurately detect whole chromosome aneuploidy in a trophectoderm biopsy and provide additional information to improve testing? SUMMARY ANSWER: Karyotypes obtained by tNGS were concordant with other validated platforms and single nucleotide polymorphism genotyping information obtained can be used for improved detection and quality control. WHAT IS KNOWN ALREADY: qPCR-based whole chromosome aneuploidy screening is highly accurate in comparison to other common methods and has been shown to improve IVF success in two randomized clinical trials. With aneuploidy screening becoming standard of care in many IVF centres, there is a need to develop platforms with high throughput, low cost capabilities. STUDY DESIGN SIZE, DURATION: Twelve well-characterized cell lines were obtained from a commercial cell line repository and 31 discarded human blastocysts were obtained from 17 IVF patients who underwent comprehensive chromosome screening (CCS). PARTICIPANTS/MATERIAL, SETTING, METHODS: All samples were processed using a unique amplification strategy which directly incorporated sequencing library adapters and barcodes. Sequencing was performed on an Ion Torrent Proton. A custom bioinformatics pipeline was used to determine the karyotype for each sample. The consistency of tNGS diagnoses with either conventional karyotyping of cell lines or quantitative real-time PCR based CCS of blastocyst biopsies was evaluated. MAIN RESULTS AND THE ROLE OF CHANCE: Overall consistency per sample of tNGS based CCS in 5-cell samples from a variety of cell lines was 99.2%. In the blinded analysis of rebiopsies of aneuploid blastocysts, an overall targeted tNGS CCS consistency of 98.7% was observed per sample. These data demonstrate the ability of tNGS based CCS to provide an accurate and high throughput evaluation of aneuploidy in the human blastocyst. LARGE SCALE DATA: Not applicable. LIMITATIONS REASONS FOR CAUTION: This study is limited to whole chromosome aneuploidy, as mosaicism and segmental aneuploidy have not been investigated. WIDER IMPLICATIONS OF THE FINDINGS: These data show an accurate, high throughput method, and with the greater depth of each amplicon sequenced in comparison to commercial kits, there is greater application available for single nucleotide polymorphism based analysis for quality control. STUDY FUNDING/COMPETING INTERESTS: This study was funded through intramural research funds provided by the Foundation for Embryonic Competence. There are no competing interests. PMID- 29186555 TI - Positive Self-perceptions of Aging Promote Healthy Eating Behavior Across the Life Span via Social-Cognitive Processes. AB - Objectives: Negative self-perceptions of aging (SPA) have been shown to result in lower levels of preventive behavior, health, and longevity. This study focuses on the understudied SPA effects on healthy eating across the life span. Moreover, it aims to provide longitudinal evidence of the psychological mechanisms behind this relationship. Method: We investigated whether SPA (T1) can predict changes in eating behavior (T3) over 1 year in 1,321 participants (T1), aged 18-92 years. The explanatory role of social-cognitive processes (T1, T2) was tested via a two step mediation analysis with multigroup modeling for different age and education levels. Results: Baseline positive SPA predicted more healthy eating at T3 (b = 0.68, SE = 0.24, p = .01), controlling for baseline eating (T1), age, education, gender, BMI, and illnesses. Self-efficacy (T1) and intention to eat healthily (T2) serially mediated this effect, indirect effect: b = 0.04, p = .02, 95% CI (0.02, 0.08). SPA had stronger effects in older and less educated participants. Discussion: This study provides important insights into the mechanisms behind positive SPA fueling successful health behavior change dynamics. Fostering more positive SPA through interventions might be especially important for vulnerable groups. Addressing SPA already in younger ages might help establish health promoting life-span dynamics.

AB - Objective: This study investigates the characteristics and trends of medication errors involving analgesic medications. Design and Methods: A retrospective analysis was conducted of analgesic-related medication errors reported to the National Poison Data System (NPDS) from 2000 through 2012. Results: From 2000 through 2012, the NPDS received 533,763 reports of analgesic-related medication errors, averaging 41,059 medication errors annually. Overall, the rate of analgesic-related medication errors reported to the NPDS increased significantly by 82.6% from 2000 to 2009, followed by a 5.7% nonsignificant decrease from 2009 to 2012. Among the analgesic categories, rates of both acetaminophen-related and opioid-related medication errors reported to the NPDS increased during 2000-2009, but the opioid error rate leveled off during 2009-2012, while the acetaminophen error rate decreased by 17.9%. Analgesic-related medication errors involved nonsteroidal anti-inflammatory drugs (37.0%), acetaminophen (35.5%), and opioids (23.2%). Children five years or younger accounted for 38.8% of analgesics-related medication errors. Most (90.2%) analgesic-related medication errors were managed on-site, rather than at a health care facility; 1.6% were admitted to a hospital, and 1.5% experienced serious medical outcomes, including 145 deaths. The most common type of medication error was inadvertently taking/given the medication twice (26.6%). Conclusions: Analgesic-related medication errors are common, and although most do not result in clinical consequences, they can have serious adverse outcomes. Initiatives associated with the decrease in acetaminophen related medication errors among young children merit additional research and potential replication as a model combining government policy and multisectoral collaboration. PMID- 29186558 TI - Essential role for phytol kinase and tocopherol in tolerance to combined light and temperature stress in tomato. AB - In a changing environment, plants need to cope with the impact of rising temperatures together with high light intensity. Here, we used lipidomics in the tomato model system to identify lipophilic molecules that enhance tolerance to combined high-temperature and high-light stress. Among several hundred metabolites, the two most strongly up-regulated compounds were alpha-tocopherol and plastoquinone/plastoquinol. Both are well-known lipid antioxidants and contribute to the protection of photosystem II (PSII) against photodamage under environmental stress. To address the protective function of tocopherol, an RNAi line (vte5) with decreased expression of VTE5 and reduced levels of alpha tocopherol was selected. VTE5 encodes phytol kinase, which acts in the biosynthetic pathway of tocopherols. vte5 suffered strong photoinhibition and photobleaching when exposed to combined high-light and high-temperature stress, but neither stress alone produced a visible phenotype. As vte5 had plastoquinone levels similar to those of the wild type under combined stress, the strong phenotype could be attributed to the lack of alpha-tocopherol. These findings suggest that VTE5 protects against combined high-light and high-temperature stress and does so by supporting alpha-tocopherol production. PMID- 29186559 TI - PHYLOSCANNER: Inferring Transmission from Within- and Between-Host Pathogen Genetic Diversity. AB - A central feature of pathogen genomics is that different infectious particles (virions, bacterial cells, etc.) within an infected individual may be genetically distinct, with patterns of relatedness amongst infectious particles being the result of both within-host evolution and transmission from one host to the next. Here we present a new software tool, phyloscanner, which analyses pathogen diversity from multiple infected hosts. phyloscanner provides unprecedented resolution into the transmission process, allowing inference of the direction of transmission from sequence data alone. Multiply infected individuals are also identified, as they harbour subpopulations of infectious particles that are not connected by within-host evolution, except where recombinant types emerge. Low level contamination is flagged and removed. We illustrate phyloscanner on both viral and bacterial pathogens, namely HIV-1 sequenced on Illumina and Roche 454 platforms, HCV sequenced with the Oxford Nanopore MinION platform, and Streptococcus pneumoniae with sequences from multiple colonies per individual. phyloscanner is available from https://github.com/BDI-pathogens/phyloscanner. PMID- 29186561 TI - Identification of 5-Fluoro ADB in Human Whole Blood in Four Death Cases. AB - Four deaths that seemed to have been caused by a designer drug occurred within a 3-week period in Sendai, Japan. In each case, the decedent possessed the same sachet, labeled "Heart Shot BLACK", which contained a dried plant material with an aromatic scent. It was revealed in our analysis that the product contained a synthetic cannabinoid receptor agonist, 5-fluoro ADB (methyl 2-[1-(5 fluoropentyl)-1H-indazole-3-carboxamide]-3,3-dimethylbutanoate, also known as 5 fluoro MDMB-PINACA), which is now classified as a restricted designer drug in Japan after it caused several casualties. For standard samples, the detection of 5-fluoro ADB in whole blood in the calibration range (0.04-4 ng/mL) was successful with recoveries of 94.6-98.1%, limits of detection of 6 pg/mL, and limits of quantification of 40 pg/mL. The intraday and interday precisions were 0.9-4.8% and 1.1-6.6%, respectively. The bias was -1.1 to 2.9%. We were able to confirm that 5-fluoro ADB was present in the blood of all four decedents at a concentration of 0.11-1.92 ng/mL. From the autopsy, toxicological findings, and circumstances surrounding the cases, it was considered that inhalation of 5 fluoro ADB could have contributed to the deaths. However, the extent to which 5 fluoro ADB contributed to the deaths remains unclear due to the current lack of toxicological information on the compound. In future research, the toxicity of 5 fluoro ADB in humans and the mechanism underlying this effect need to be elucidated. PMID- 29186560 TI - The Intracellular Localization of the Vanillin Biosynthetic Machinery in Pods of Vanilla planifolia. AB - Vanillin is the most important flavor compound in the vanilla pod. Vanilla planifolia vanillin synthase (VpVAN) catalyzes the conversion of ferulic acid and ferulic acid glucoside into vanillin and vanillin glucoside, respectively. Desorption electrospray ionization mass spectrometry imaging (DESI-MSI) of vanilla pod sections demonstrates that vanillin glucoside is preferentially localized within the mesocarp and placental laminae whereas vanillin is preferentially localized within the mesocarp. VpVAN is present as the mature form (25 kDa) but, depending on the tissue and isolation procedure, small amounts of the immature unprocessed form (40 kDa) and putative oligomers (50, 75 and 100 kDa) may be observed by immunoblotting using an antibody specific to the C terminal sequence of VpVAN. The VpVAN protein is localized within chloroplasts and re-differentiated chloroplasts termed phenyloplasts, as monitored during the process of pod development. Isolated chloroplasts were shown to convert [14C]phenylalanine and [14C]cinnamic acid into [14C]vanillin glucoside, indicating that the entire vanillin de novo biosynthetic machinery converting phenylalanine to vanillin glucoside is present in the chloroplast. PMID- 29186562 TI - Adaptation of an Evidence-Based Diabetes Management Intervention for Delivery in Community Settings: Findings From a Pilot Randomized Effectiveness Trial. AB - Objective: To adapt an evidence-based intervention targeting diabetes management in adolescents with poorly controlled type 1 diabetes for use in a community setting by community health workers (CHWs) and to conduct pilot testing of the new intervention, REACH for Control (RFC). The study was conducted as a collaboration between university researchers and a federally qualified health center. Methods: In a pilot effectiveness trial, feasibility and acceptability of RFC were evaluated based on participant enrollment, treatment dose, and consumer satisfaction. RFC effects on adolescent adherence, health outcomes, and quality of life were also assessed. The trial used a parallel group design. Families were randomized to 6 months of RFC plus standard medical care (n = 26) or standard care (SC) only (n = 24). Data were collected at baseline and 7-month posttest. A mixed-methods approach was used to analyze data. Results: Qualitative analyses suggested that caregivers viewed RFC and delivery of a home-based intervention by CHWs positively. Furthermore, adolescents who received RFC had statistically significant (p = .05) and clinically meaningful improvements in hemoglobin A1c (HbA1c) (0.7%) and reported significant improvements in quality of life from baseline to follow-up (p = .001). No significant changes were found for adolescents in standard medical care. However, while dose of primary intervention session delivered was acceptable, dose of follow-up sessions used for skills practice was low. Conclusions: Results provide preliminary support for RFC's acceptability and effectiveness to improve health status and quality of life when used in community settings serving high-risk, low-income families. Additional testing in a full-scale effectiveness trial appears warranted. PMID- 29186564 TI - Erratum to: Sala L, et al.

AB - This study evaluated the oncologic outcomes and complications of cervical cancer patients in terms of CT-based image-guided brachytherapy (IGBT) parameters. Of 68 cervical cancer patients treated with definitive radiotherapy/concurrent chemoradiotherapy, most received whole-pelvis external beam RT (EBRT) of 40 Gy in 20 fractions, pelvic EBRT with central shield of 10 Gy in 5 fractions, and CT based IGBT of 18 Gy in 3 fractions prescribed to point A. Cumulative EBRT and IGBT doses were calculated as the total equivalent dose in 2 Gy fractions (EQD2). The median follow-up was 31 (3-52) months. The 2-year overall survival, local control, pelvic control, and disease-free survival rates of the 68 patients were 92%, 83%, 82% and 73%, respectively. The HR-CTV D90, length from the tandem axis to left/right margin of the HR-CTV (T-LR), and HR-CTV volume were significant IGBT parameters for predicting local/pelvic control. Patients who received an HR CTV D90 of >60 Gy, compared with <=60 Gy, had significantly better local/pelvic control. Furthermore, 70 Gy was a marginally significant HR-CTV D90 cut-off affecting local control. T-LR was an independent IGBT parameter predicting local/pelvic control on multivariate analysis. Three patients developed Grade 3 or higher treatment-related complications. The D2cm3 of organs at risk were not significant predictors of complications. Future challenges for further improving outcomes include additional interstitial needles for irregularly shaped HR-CTVs, and moderate dose escalation, especially for patients with poor tumor responses. PMID- 29186566 TI - Long-Term Perspectives of Family Quality of Life Following Music Therapy With Young Children on the Autism Spectrum: A Phenomenological Study. AB - Background: Parents of children on the autism spectrum have consistently reported feeling uncertain in their parenting role, and desire more practical advice from service providers about how to support their child in the home. There is growing recognition of the need for interventions to provide support to the family as well as fostering child development outcomes. Objective: This study explores mothers' follow-up perspectives of family-centered music therapy (FCMT) four years after participating in a 16-week home-based program, and therefore provides a unique long-term viewpoint on FCMT outcomes. Methods: Eight mothers who previously participated in FCMT sessions with their young children on the autism spectrum were interviewed to explore their perception of any long-term outcomes. Results: A descriptive phenomenological analysis revealed five global themes, including: improvement in mothers' confidence to engage their child; rare opportunities for mutual mother-child enjoyment; improved child social communication and quality of life; mothers' new understanding of the child's interests and strengths; and more opportunities for continuing the child's interest in music. Conclusions: Mothers perceived long-term benefits to social relationships within the family, leading to perceived enrichment in child and family quality of life following music therapy sessions. PMID- 29186567 TI - Dynamic m6A modification regulates local translation of mRNA in axons. AB - N6-methyladenosine (m6A) is a reversible modification in mRNA and has been shown to regulate processing, translation and decay of mRNA. However, the roles of m6A modification in neuronal development are still not known. Here, we found that the m6A eraser FTO is enriched in axons and can be locally translated. Axon-specific inhibition of FTO by rhein, or compartmentalized siRNA knockdown of Fto in axons led to increases of m6A levels. GAP-43 mRNA is modified by m6A and is a substrate of FTO in axons. Loss-of-function of this non-nuclear pool of FTO resulted in increased m6A modification and decreased local translation of axonal GAP-43 mRNA, which eventually repressed axon elongation. Mutation of a predicted m6A site in GAP-43 mRNA eliminated its m6A modification and exempted regulation of its local translation by axonal FTO. This work showed an example of dynamic internal m6A demethylation of non-nuclear localized mRNA by the demethylase FTO. Regulation of m6A modification of axonal mRNA by axonal FTO might be a general mechanism to control their local translation in neuronal development. PMID- 29186568 TI - Germline SUFU mutation carriers and medulloblastoma: clinical characteristics, cancer risk, and prognosis. AB - Background: Germline mutations of suppressor of fused homolog (SUFU) predispose to sonic hedgehog (SHH) medulloblastoma. Germline SUFU mutations have been reported in nevoid basal cell carcinoma syndrome (NBCCS), but little is known about the cancer risk and clinical spectrum. Methods: We performed a retrospective review of all patients with medulloblastoma and a germline SUFU mutation in France. Results: Twenty-two patients from 17 families were identified with medulloblastoma and a germline SUFU mutation (median age at diagnosis: 16.5 mo). Macrocrania was present in 20 patients, but only 5 met the diagnostic criteria for NBCCS. Despite treatment with surgery and chemotherapy, to avoid radiotherapy in all patients except one, the outcome was worse than expected for SHH medulloblastoma, due to the high incidence of local relapses (8/22 patients) and second malignancies (n = 6 in 4/22 patients). The 5-year progression-free survival and overall survival rates were 42% and 66%. Mutations were inherited in 79% of patients, and 34 additional SUFU mutation carriers were identified within 14 families. Medulloblastoma penetrance was incomplete, but higher than in Patched 1 (PTCH1) mutation carriers. Besides medulloblastoma, 19 other tumors were recorded among the 56 SUFU mutation carriers, including basal cell carcinoma (BCC) in 2 patients and meningioma in 3 patients. Conclusion: Germline SUFU mutations strongly predispose to medulloblastoma in the first years of life, with worse prognosis than usually observed for SHH medulloblastoma. The clinical spectrum differs between SUFU and PTCH1 mutation carriers, and BCC incidence is much lower in SUFU mutation carriers. The optimal treatment of SUFU mutation associated medulloblastoma has not been defined. PMID- 29186569 TI - Activation Inventories after Exposure to DD/DT Neutrons in Safety Analysis of Nuclear Fusion Installations. AB - Irradiations with 14 MeV fusion neutrons are planned at Joint European Torus (JET) in DT operations with the objective to validate the calculation of the activation of structural materials in functional materials expected in ITER and fusion plants. This study describes the activation and dose rate calculations performed for materials irradiated throughout the DT plasma operation during which the samples of real fusion materials are exposed to 14 MeV neutrons inside the JET vacuum vessel. Preparatory activities are in progress during the current DD operations with dosimetry foils to measure the local neutron fluence and spectrum at the sample irradiation position. The materials included those used in the manufacturing of the main in-vessel components, such as ITER-grade W, Be, CuCrZr, 316 L(N) and the functional materials used in diagnostics and heating systems. The neutron-induced activities and dose rates at shutdown were calculated by the FISPACT code, using the neutron fluxes and spectra that were provided by the preceding MCNP neutron transport calculations. PMID- 29186570 TI - Comparative efficacy of drugs for treating giardiasis: a systematic update of the literature and network meta-analysis of randomized clinical trials. AB - Background: Giardiasis is the commonest intestinal protozoal infection worldwide. The current first-choice therapy is metronidazole. Recently, other drugs with potentially higher efficacy or with fewer and milder side effects have increased in popularity, but evidence is limited by a scarcity of randomized controlled trials (RCTs) comparing the many treatment options available. Network meta analysis (NMA) is a useful tool to compare multiple treatments when there is limited or no direct evidence available. Objectives: To compare the efficacy and side effects of all available drugs for the treatment of giardiasis. Methods: We selected all RCTs included in systematic reviews and expert reviews of all treatments for giardiasis published until 2014, extended the systematic literature search until 2016, and identified new studies by scanning reference lists for relevant studies. We then conducted an NMA of all available treatments for giardiasis by comparing parasitological cure (efficacy) and side effects. Results: We identified 60 RCTs from 58 reports (46 from published systematic reviews, 8 from reference lists and 4 from the updated systematic search). Data from 6714 patients, 18 treatments and 42 treatment comparisons were available. Tinidazole was associated with higher parasitological cure than metronidazole [relative risk (RR) 1.23, 95% CI 1.12-1.35] and albendazole (RR 1.35, 95% CI 1.21 1.50). Taking into consideration clinical efficacy, side effects and amount of the evidence, tinidazole was found to be the most effective drug. Conclusions: We provide additional evidence that single-dose tinidazole is the best available treatment for giardiasis in symptomatic and asymptomatic children and adults. PMID- 29186572 TI - Hydroxycloroquine blood concentration in lupus nephritis: a determinant of disease outcome? AB - Background: Hydroxychloroquine (HCQ) is a recommended drug in systemic lupus erythematosus (SLE). It has a long terminal half-life, making it an attractive target for therapeutic drug monitoring. The aim of this study was to establish a relationship between blood HCQ concentration and lupus nephritis activity. Methods: We conducted a retrospective observational study with data collected from clinical and laboratory records. Inclusion criteria were patients followed in the lupus clinic with biopsy-proven International Society of Nephrology/Renal Pathology Society Classes III, IV or V lupus nephritis on HCQ for at least 3 months (200-400 mg daily) and with HCQ levels measured during treatment. Exclusion criteria were patients on renal replacement therapy at baseline or patients lost to follow-up. Results: In 171 patients, the HCQ level was measured in 1282 samples. The mean HCQ blood level was 0.75+/-0.54mg/L and it was bimodally distributed. An HCQ level <0.20 mg/L [232 samples (18.1%)] appeared to define a distinct group of abnormally low HCQ levels. For patients in complete or partial remission at baseline compared with those remaining in remission, patients with renal flare during follow-up had a significantly lower average HCQ level (0.59 versus 0.81 mg/L; P= 0.005). Our data suggest an HCQ target level to reduce the likelihood of renal flares >0.6 mg/L (600 ng/mL) in those patients with lupus nephritis. Conclusion: HCQ level monitoring may offer a new approach to identify non-adherent patients and support them appropriately. We propose an HCQ minimum target level of at least 0.6 mg/L to reduce the renal flare rate, but this will require a prospective study for validation. PMID- 29186571 TI - Oxygen gradients can determine epigenetic asymmetry and cellular differentiation via differential regulation of Tet activity in embryonic stem cells. AB - Graded levels of molecular oxygen (O2) exist within developing mammalian embryos and can differentially regulate cellular specification pathways. During differentiation, cells acquire distinct epigenetic landscapes, which determine their function, however the mechanisms which regulate this are poorly understood. The demethylation of 5-methylcytosine (5mC) is achieved via successive oxidation reactions catalysed by the Ten-Eleven-Translocation (Tet) enzymes, yielding the 5 hydroxymethylcytosine (5hmC) intermediate. These require O2 as a co-factor, and hence may link epigenetic processes directly to O2 gradients during development. We demonstrate that the activities of Tet enzymes display distinct patterns of [O2]-dependency, and that Tet1 activity, specifically, is subject to differential regulation within a range of O2 which is physiologically relevant in embryogenesis. Further, differentiating embryonic stem cells displayed a transient burst of 5hmC, which was both dependent upon Tet1 and inhibited by low (1%) [O2]. A GC-rich promoter region within the Tet3 locus was identified as a significant target of this 5mC-hydroxylation. Further, this region was shown to associate with Tet1, and display the histone epigenetic marks, H3K4me3 and H3K27me3, which are characteristic of a bivalent, developmentally 'poised' promoter. We conclude that Tet1 activity, determined by [O2] may play a critical role in regulating cellular differentiation and fate in embryogenesis. PMID- 29186575 TI - DNA as UV light-harvesting antenna. AB - The ordered structure of UV chromophores in DNA resembles photosynthetic light harvesting complexes in which quantum coherence effects play a major role in highly efficient directional energy transfer. The possible role of coherent excitons in energy transport in DNA remains debated. Meanwhile, energy transport properties are greatly important for understanding the mechanisms of photochemical reactions in cellular DNA and for DNA-based artificial nanostructures. Here, we studied energy transfer in DNA complexes formed with silver nanoclusters and with intercalating dye (acridine orange). Steady-state fluorescence measurements with two DNA templates (15-mer DNA duplex and calf thymus DNA) showed that excitation energy can be transferred to the clusters from 21 and 28 nucleobases, respectively. This differed from the DNA-acridine orange complex for which energy transfer took place from four neighboring bases only. Fluorescence up-conversion measurements showed that the energy transfer took place within 100 fs. The efficient energy transport in the Ag-DNA complexes suggests an excitonic mechanism for the transfer, such that the excitation is delocalized over at least four and seven stacked bases, respectively, in one strand of the duplexes stabilizing the clusters. This result demonstrates that the exciton delocalization length in some DNA structures may not be limited to just two bases. PMID- 29186573 TI - Conformational dynamics of the Hop1 HORMA domain reveal a common mechanism with the spindle checkpoint protein Mad2. AB - The HORMA domain is a highly conserved protein-protein interaction module found in eukaryotic signaling proteins including the spindle assembly checkpoint protein Mad2 and the meiotic HORMAD proteins. HORMA domain proteins interact with short 'closure motifs' in partner proteins by wrapping their C-terminal 'safety belt' region entirely around these motifs, forming topologically-closed complexes. Closure motif binding and release requires large-scale conformational changes in the HORMA domain, but such changes have only been observed in Mad2. Here, we show that Saccharomyces cerevisiae Hop1, a master regulator of meiotic recombination, possesses conformational dynamics similar to Mad2. We identify closure motifs in the Hop1 binding partner Red1 and in Hop1 itself, revealing that HORMA domain-closure motif interactions underlie both Hop1's initial recruitment to the chromosome axis and its self-assembly on the axis. We further show that Hop1 adopts two distinct folded states in solution, one corresponding to the previously-observed 'closed' conformation, and a second more extended state in which the safety belt region has disengaged from the HORMA domain core. These data reveal strong mechanistic similarities between meiotic HORMADs and Mad2, and provide a mechanistic basis for understanding both meiotic chromosome axis assembly and its remodeling by the AAA+ ATPase Pch2/TRIP13. PMID- 29186574 TI - TorsinA dysfunction causes persistent neuronal nuclear pore defects. AB - A critical challenge to deciphering the pathophysiology of neurodevelopmental disease is identifying which of the myriad abnormalities that emerge during CNS maturation persist to contribute to long-term brain dysfunction. Childhood-onset dystonia caused by a loss-of-function mutation in the AAA+ protein torsinA exemplifies this challenge. Neurons lacking torsinA develop transient nuclear envelope (NE) malformations during CNS maturation, but no NE defects are described in mature torsinA null neurons. We find that during postnatal CNS maturation torsinA null neurons develop mislocalized and dysfunctional nuclear pore complexes (NPC) that lack NUP358, normally added late in NPC biogenesis. SUN1, a torsinA-related molecule implicated in interphase NPC biogenesis, also exhibits localization abnormalities. Whereas SUN1 and associated nuclear membrane abnormalities resolve in juvenile mice, NPC defects persist into adulthood. These findings support a role for torsinA function in NPC biogenesis during neuronal maturation and implicate altered NPC function in dystonia pathophysiology.

PMID- 29186577 TI - Proposed Optimal Fluoroscopic Targets for Cooled Radiofrequency Neurotomy of the Sacral Lateral Branches to Improve Clinical Outcomes: An Anatomical Study. AB - Background: Current sacroiliac joint (SIJ) cooled radiofrequency (RF) is based on fluoroscopic anatomy of lateral branches (LBs) in three specimens. Recent studies confirm significant variation in LB positions. Objectives: To determine if common fluoroscopic needle placements for cooled SIJ RF are adequate to lesion all S1-3 LBs. If not, would different targets improve lesion accuracy? Methods: The LBs of 20 cadavers were dissected bilaterally (40 SIJs), and 26 G radiopaque wires were sutured to the LBs. With a 10-mm radius ruler centered at each foramen, standard targets were assessed, as judged by a clockface on the right, for S1 and S2 at 2:30, 4:00, and 5:30 positions and at S3 at 2:30 and 4:00. Mirror image targets were assessed on the left. Assuming an 8-mm lesion diameter, the percentage of LBs that would not be ablated for each level was determined. Imaging through the superior end plate of S1 was compared against segment specific (SS) imaging. Results: Nine point four percent of LBs would not be ablated at S1 vs 0.99% at S2 vs 35% at S3, and 60% of the 40 SIJs would be completely denervated using current targets. SS imaging did not improve results. Alternate target locations could improve the miss rate to 2.8% at S1 and 0% at S3 and would ablate all LBs in 95% of SIJs. Conclusions: Using a conservative 8-mm lesion measurement, contemporary cooled RF needle targets are inadequate to lesion all target LBs. Modifications to current targets are recommended to increase the effectiveness of the procedure. PMID- 29186579 TI - Insecticide Susceptibility Screening Against Culex and Aedes (Diptera: Culicidae) Mosquitoes From the United States. AB - Mosquitoes exposed to sublethal doses of insecticides may be selected for resistance to insecticide active ingredients (AIs). Mosquitoes are exposed to AIs through agricultural, public/private mosquito control programs, homeowners, and other sources. Hence, mosquito control programs should routinely measure the resistance/susceptibility status of mosquito populations of public health concern. The objectives here were to determine resistance status for six AIs used in adult mosquito control in the United States to assess how resistance/susceptibility differs between AI, mosquito species (states where > 1 species collected), and between years (some populations sampled for 2 yr). Field collected eggs from 21 mosquito populations of six different species or hybrid species (Aedes albopictus Skuse [Diptera: Culicidae], Aedes aegypti L. [Diptera: Culicidae], Culex nigripalpus Theobald, Culex pipiens L. [Diptera: Culicidae], Culex quinquefasciatus Say [Diptera: Culicidae], Cx. pipiens/quinquefasciatus) were obtained. Centers for Disease Control and Prevention bottle bioassays were used to assess the resistance/susceptibility status for six AIs (bifenthrin, deltamethrin, etofenprox, malathion, permethrin, and phenothrin). World Health Organization guidelines were used to classify mosquitoes as susceptible (98-100% mortality at diagnostic time [DT]), possibly resistant (80-97% mortality at DT), or resistant (<80% mortality at DT). Significant differences were observed in mosquito susceptibility/resistance between species and AIs. In states where both Aedes and Culex were collected, the odds of exhibiting resistance in Culex were 68-69 times higher than Aedes (Texas odds ratio: 69.30; 95% confidence interval: 5.86, 819.44; P = 0.001; North Carolina odds ratio: 67.99; 95% confidence interval: 15.21, 303.94; P < 0.0001). Some level of resistance was detected against all tested AIs in several mosquito populations and some varied between 2015 and 2016.

PMID- 29186582 TI - Safety of Spinal Cord Stimulation in Patients Who Routinely Use Anticoagulants. AB - Objective: We assess the safety of performing the epidural placement or revision of spinal cord stimulation (SCS) in patients whose anticoagulation has been held (termed "anticoagulant-suspended" patients) in accordance with the 2017 Neurostimulation Appropriateness Consensus Committee (NACC) guidelines. Subjects: Patients undergoing SCS were included in this institutional review board-approved study. Design: A retrospective analysis of a prospectively collected database was performed. Any adverse event occurring within 90 days after SCS lead placement/revision was included. Results: A total of 225 patients who had a total of 239 surgeries including lead placement or lead revision were included; 182 patients were not on anticoagulants, 37 patients used one anticoagulant, and six patients used two or more anticoagulants. There were 13 adverse events. Anticoagulant use as a whole had no significant relationship to operative or postoperative adverse effects (chi2(1) = 1.613, P > 0.05). No anticoagulant on its own contributed significantly to adverse events; however, a small set of surgical cases showed a significantly greater incidence of adverse events for patients on enoxaparin used in combination with other anticoagulants (P < 0.05, N = 4). Conclusions: This study is the first to demonstrate that anticoagulant suspended patients have no increased risk of perioperative hemorrhagic or thromboembolic adverse effects following SCS surgery compared with nonanticoagulated patients. The findings of this study validate the safety of neuromodulation in anticoagulation-suspended patients, concurring with the findings of previously described case studies, which anecdotally described neuromodulation outcomes in patients whose anticoagulation regimen had been temporarily held.

PMID- 29186583 TI - Transcriptomic Analysis of Kalopanax septemlobus and Characterization of KsBAS, CYP716A94 and CYP72A397 Genes Involved in Hederagenin Saponin Biosynthesis. AB - Kalopanax septemlobus, commonly named the castor aralia tree, is a highly valued woody medicinal tree belonging to the family Araliaceae. Kalopanax septemlobus contains approximately 15 triterpenoid saponins primarily constituted of hederagenin aglycones. Hederagenin is a representative precursor for hemolytic saponin in plants. In the present study, transcriptome analysis was performed to discover genes involved in hederagenin saponin biosynthesis in K. septemlobus. De novo assembly generated 82,698 unique sequences, including 17,747 contigs and 64,951 singletons, following 454 pyrosequencing. Oxidosqualene cyclases (OSCs) are enzymes that catalyze the formation of diverse triterpene skeletons from 2,3 oxidosqualene. Heterologous expression of an OSC sequence in yeast revealed that KsBAS is a beta-amyrin synthase gene. Cytochrome P450 genes (CYPs) make up a supergene family in the plant genome and play a key role in the biosynthesis of sapogenin aglycones. In total, 95 contigs and 110 singletons annotated as CYPs were obtained by sequencing the K. septemlobus transcriptome. By heterologous expression in yeast, we found that CYP716A94 was beta-amyrin 28-oxidase involved in oleanolic acid production from beta-amyrin, and CYP72A397 was oleanolic acid 23-hydroxylase involved in hederagenin production from oleanolic acid. Engineered yeast co-expressing KsBAS, CYP716A94 and CYP72A397 produced hederagenin. Kalopanax septemlobus CYP72A397 is a novel CYP enzyme that synthesizes hederagenin aglycone from oleanolic acid as a single product. In conclusion, we characterized three genes participating in sequential steps for hederagenin biosynthesis from beta-amyrin, which are likely to play a major role in hederagenin saponin biosynthesis in K. septemlobus. PMID- 29186581 TI - Type-B ARRs Control Carpel Regeneration Through Mediating AGAMOUS Expression in Arabidopsis. AB - Plants are known for their capacity to regenerate organs, such as shoot, root and floral organs. Recently, a number of studies contributed to understanding the mechanisms of shoot and root regeneration. However, the mechanisms underlying floral organ regeneration are largely unknown. In this study, we established a carpel regeneration system in which two types of carpels were induced by exogenous cytokinin. For type I, all the floral organs in the regenerated inflorescence were transformed into carpels. For type II, carpels were generated directly from callus. The transcript level of AGAMOUS (AG), the carpel identity gene, was up-regulated during carpel induction. The expression signals of AG were detected in the initiating carpel primordia and regenerating carpels, and co localized with those of two Type-B ARABIDOPSIS RESPONSE REGULATORs (ARRs), ARR1 and ARR10. Repression of either AG or type-B ARRs reduced carpel regeneration. Binding analyses showed that ARR1 and ARR10 directly bound to transcriptional regulatory regions of AG and positively regulated its expression. In addition, the expression of type-B ARRs overlapped with that of AG in the floral primordia in planta. Defects in type-B ARRs reduced the number of carpels. The results indicate that type-B ARRs control carpel regeneration through activating AG expression. Our results provide new information for understanding the mechanism of carpel formation. PMID- 29186585 TI - Fatality Following Ingestion of Tetrahydrofuranylfentanyl, U-49900 and Methoxy Phencyclidine. AB - Novel psychoactive substances (NPS), and specifically novel opioids, continue to cause adverse events, including death, within drug-using populations. As the number of opioid-related overdoses continues to increase, laboratories have identified the emergence of new fentanyl analogues and other synthetic opioid related drugs. Tetrahydrofuranylfentanyl (THFF) has been identified in Europe and the United States as an emerging novel opioid, causing death in at least 15 drug using individuals to date. THFF is structurally similar to furanylfentanyl, a previously characterized novel opioid responsible for numerous adverse events, including death. In this case report, THFF, U-49900 and methoxy-phencyclidine were identified in postmortem blood and urine specimens collected after a suspected overdose. As part of the death investigation, an unknown substance was collected from the scene and analytically confirmed as THFF and U-49900. To further assist laboratories in identifying THFF ingestion, metabolic profiling was conducted using pooled human liver microsomes. Characterized metabolites were then confirmed in the specimens collected during this investigation. In total, seven metabolites were identified for THFF, most notably THF-norfentanyl and hydroxyl-THFF. THF-norfentanyl provides utility as a biomarker because it is a unique metabolite of THFF. 4-Anilino-N-phenethylpiperidine (4-ANPP) and its metabolite, hydroxyl-4-ANPP, were identified in microsomal incubations and collected specimens, but usefulness as biomarkers is limited due to commonality between other fentanyl analogues and co-ingestion as a synthesis precursor. To our knowledge, this case report is the first to document a fatality after ingestion of THFF and U-49900 in the United States. PMID- 29186586 TI - Relationship between stomatal density, size and speed of opening in Sumatran rainforest species. AB - Recent studies have suggested that an association between size and speed of stomatal opening of stomata within taxa is likely to play a role in photosynthesis and transpiration. In this study we investigate whether this correlation applies for seedlings of 11 rainforest species from different taxa, and whether differences in stomatal and gas exchange parameters were related to initial growth under field and controlled conditions. The experiment was conducted on seedlings of nine late successional species and two early successional species, placed in full sunlight or 70% shade. We assessed density, size, length and width of guard cells, coupled with gas exchange parameters in the transition from darkness to light, recording minimum stomatal conductance during daytime darkness (gs-dark), operating maximum stomatal conductance (gs op), speed of stomatal opening and the time to reach 50% conductance (T-50%). All stomata and gas exchange parameters were different between species. Shade significantly affected size and density, and all gas exchange parameters except gs-op were different between light situations. Stomatal size correlated negatively with speed of opening and positively with T-50%, confirming that smaller stomata open faster than large stomata. The two early successional species were very different in stomatal size and density, and in response to light. Anatomic parameters and physiological traits were not related to height growth, but gs-dark, gs-op and speed of stomatal opening were associated with biomass growth in a subselection of six late successional species. PMID- 29186587 TI - Effective Online Bayesian Phylogenetics via Sequential Monte Carlo with Guided Proposals. AB - Modern infectious disease outbreak surveillance produces continuous streams of sequence data which require phylogenetic analysis as data arrives. Current software packages for Bayesian phylogenetic inference are unable to quickly incorporate new sequences as they become available, making them less useful for dynamically unfolding evolutionary stories. This limitation can be addressed by applying a class of Bayesian statistical inference algorithms called sequential Monte Carlo (SMC) to conduct online inference, wherein new data can be continuously incorporated to update the estimate of the posterior probability distribution. In this article, we describe and evaluate several different online phylogenetic sequential Monte Carlo (OPSMC) algorithms. We show that proposing new phylogenies with a density similar to the Bayesian prior suffers from poor performance, and we develop "guided" proposals that better match the proposal density to the posterior. Furthermore, we show that the simplest guided proposals can exhibit pathological behavior in some situations, leading to poor results, and that the situation can be resolved by heating the proposal density. The results demonstrate that relative to the widely used MCMC-based algorithm implemented in MrBayes, the total time required to compute a series of phylogenetic posteriors as sequences arrive can be significantly reduced by the use of OPSMC, without incurring a significant loss in accuracy.

PMID- 29186590 TI - Frequency of Multidrug-Resistant Organisms Cultured From Urine of Children Undergoing Clean Intermittent Catheterization. AB - Background: Children undergoing CIC frequently have positive urine culture results and receive many antimicrobial agents. Subsequently, this population is at high risk for infections caused by antimicrobial-resistant bacteria. Resistant pathogens, such as vancomycin-resistant Enterococcus (VRE), carbapenem-resistant Enterobacteriaceae (CRE), and organisms that produce extended-spectrum beta lactamases (ESBLs), which are third-generation cephalosporin resistant (3GCR), are of particular concern. Methods: In this retrospective study, all urine culture results and antimicrobial-susceptibility testing results were obtained between January 2008 and December 2014 from the electronic health record of children <=18 years of age who were undergoing CIC (n = 14 832). Isolates were identified as VRE, CRE, or 3GCR. Organisms of the same type that were obtained in the same year and with identical antibiotic susceptibilities from the same patient were excluded. Simple linear regression was used to determine the association between year and rates of resistance. Results: A total of 3997 positive culture results were included in this analysis. Of all Enterococcus isolates for which susceptibility results were available, 4.6% were VRE, 11.1% of all isolates that belonged to the Enterobacteriaceae family were 3GCR, and 0.4% of eligible isolates were CRE. There were significantly higher rates of resistance to third-generation cephalosporins and CRE in 2014 than in 2008 (P < .01). Simple linear regression revealed a significant association between year and rate for resistance to third-generation cephalosporins but not for CRE or VRE. The rate of increase in resistance to third-generation cephalosporins in patients who required CIC was higher than that in patients who did not need CIC. Conclusions: The rate of resistance to third-generation cephalosporins has increased significantly in the past 7 years in children undergoing CIC, which indicates that careful monitoring is warranted for continued increases in antimicrobial-resistant organisms in this unique patient population. PMID- 29186589 TI - Detergent Insoluble Proteins and Inclusion Body-Like Structures Immunoreactive for PRKDC/DNA-PK/DNA-PKcs, FTL, NNT, and AIFM1 in the Amygdala of Cognitively Impaired Elderly Persons. AB - Misfolded protein in the amygdala is a neuropathologic feature of Alzheimer disease and many other neurodegenerative disorders. We examined extracts from human amygdala (snap-frozen at autopsy) to investigate whether novel and as yet uncharacterized misfolded proteins would be detectable. Polypeptides from the detergent-insoluble, urea-soluble protein fractions of amygdala were interrogated using liquid chromatography-electrospray ionization-tandem mass spectrometry. Among the detergent-insoluble proteins identified in amygdala of demented subjects but not controls were Tau, TDP-43, Abeta, alpha-synuclein, and ApoE. Additional detergent-insoluble proteins from demented subjects in the high molecular weight portion of SDS gels included NNT, TNIK, PRKDC (DNA-PK, or DNA PKcs), ferritin light chain (FTL), AIFM1, SYT11, STX1B, EAA1, COL25A1, M4K4, CLH1, SQSTM, SYNJ1, C3, and C4. In follow-up immunohistochemical experiments, NNT, TNIK, PRKDC, AIFM1, and FTL were observed in inclusion body-like structures in cognitively impaired subjects' amygdalae. Double-label immunofluorescence revealed that FTL and phospho-PRKDC immunoreactivity colocalized partially with TDP-43 and/or Tau inclusion bodies. Western blots showed high-molecular weight "smears", particularly for NNT and PRKDC. A preliminary genetic association study indicated that rare NNT, TNIK, and PRKDC gene variants had nominally significant association with Alzheimer-type dementia risk. In summary, novel detergent insoluble proteins, with evidence of proteinaceous deposits, were found in amygdalae of elderly, cognitively impaired subjects. PMID- 29186592 TI - Beta-2 microglobulin clearance in high-flux dialysis and convective dialysis modalities: a meta-analysis of published studies. AB - Background: Recent meta-analyses suggest that higher removal of beta-2 microglobulin (beta2M) with either high-flux (HFD) dialysis or hemodiafiltration (HDF) may be associated with decreased total and cardiovascular mortality in dialysis patients. However, there are limited data about the performance of high flux dialyzers and/or convective therapies in removing beta2M. Methods: This is a random effects meta-analysis and meta-regression of data extracted from randomized controlled trials and observational studies in hemodialysis, hemofiltration and HDF regarding the efficiency of high flux dialyzers to remove beta2M. Studies were searched using ProQuest in SCOPUS, EMBASE and MEDLINE. Results: We included 69 studies from 1 January 2001 to 12 June 2017 on 1879 patients with 6771 available measurements. Average beta2M clearance was 48.75 mL/min [95% confidence interval (CI) 42.50-55.21] for conventional HF dialysis, and 87.06 mL/min (95% CI 75.08-99.03) for convective therapies (hemofiltration and HDF) with substantial heterogeneity among studies [P (Q) <= 0.001]. In multivariable meta-regression analyses, we found significantly higher beta2M clearance for polyarylethersulfone dialyzers when used for HFD and polysulfone membranes in convective therapies. However, the mass of beta2M removed into the dialysate did not depend on membrane material. Adjusted dialysate-side (-22.279, 95% CI -9.8 to -34.757, P < 0.001) beta2M clearances were significantly lower than whole blood clearances, suggesting that adsorption contributes substantially to beta2M removal. Higher Kuf, blood flow and substitution fluid rates but not dialysate flow rates were associated with statistically significant and clinically meaningful elevation in beta2M clearance from the body independent of the dialysis modality. Conclusions: Membrane composition and characteristics, modality (convective versus diffusive), blood flow rates and substitution fluid rates in HDF play a significant role in the efficient removal of beta2M from the body in both diffusive and convective dialysis. PMID- 29186593 TI - Complex Models of Sequence Evolution Require Accurate Estimators as Exemplified with the Invariable Site Plus Gamma Model. AB - The invariable site plus $?Gamma$ model (I$+?Gamma)$ is widely used to model rate heterogeneity among alignment sites in maximum likelihood and Bayesian phylogenetic analyses. The proof that the I$+$ continuous $?Gamma$ model is identifiable (model parameters can be inferred correctly given enough data) has increased the creditability of its application to phylogeny reconstruction. However, most phylogenetic software implement the I$+$ discrete $?Gamma$ model, whose identifiability is likely but unproven. How well the parameters of the I$+$ discrete $?Gamma$ model are estimated is still disputed. Especially the correlation between the fraction of invariable sites and the fractions of sites with a slow evolutionary rate is discussed as being problematic. We show that optimization heuristics as implemented in frequently used phylogenetic software (PhyML, RAxML, IQ-TREE, and MrBayes) cannot always reliably estimate the shape parameter, the proportion of invariable sites, and the tree length. Here, we propose an improved optimization heuristic that accurately estimates the three parameters. While research efforts mainly focus on tree search methods, our results signify the equal importance of verifying and developing effective estimation methods for complex models of sequence evolution. PMID- 29186594 TI - Resection of Temporal Neocortex During Multiple Hippocampal Transections for Mesial Temporal Lobe Epilepsy Does not Affect Seizure or Memory Outcome. AB - BACKGROUND: Multiple hippocampal transection (MHT) is a surgical treatment for mesial temporal lobe epilepsy associated with improved postoperative neuropsychological outcomes compared with lobectomy. OBJECTIVE: To determine whether resection of the amygdala and anterior temporal neocortex during MHT affects postoperative seizure/memory outcome. METHODS: Seventeen patients with normal magnetic resonance imaging and stereo-electroencephalogram-proven drug resistant dominant mesial temporal lobe epilepsy were treated with MHT. Nine patients underwent MHT alone (MHT-) and 8 patients underwent MHT plus removal of the amygdala and anterior 4.5 cm of temporal neocortex lateral to the fusiform gyrus (MHT+). Verbal and visual-spatial memory were assessed in all patients preoperatively and in 14 patients postoperatively using the Wechsler Memory Scale. Postoperative seizure control was assessed at 12 months for all patients. RESULTS: Overall, 11 of 17 patients (64.7%) were Engel class 1 at 1 year (6/9 MHT , 5/8 MHT+, P = .38), and 10 of 14 patients (71.4%) had no significant postoperative decline in either verbal or visual memory (6/8 MHT-, 4/6 MHT+, P = .42). Verbal memory declined in 2 of 8 MHT- and 1 of 6 MHT+ patients, and visual memory declined in 1 of 8 MHT- and 2 of 6 MHT+ patients. Two patients had improved visual memory postoperatively, both in the MHT+ group. CONCLUSION: MHT on the dominant side is associated with high rates of seizure freedom and favorable memory preservation outcomes regardless of the extent of neocortical resection. Preservation of the temporal neocortex and amygdala during MHT does not appear to decrease the risk of postoperative memory decline, nor does it alter seizure outcome. PMID- 29186595 TI - Treatment of Recurrent Intracranial Aneurysms After Neck Clipping: Novel Classification Scheme and Management Strategies. AB - BACKGROUND: Recurrent aneurysms after initial clipping have been discussed as an important issue in the surgical management of aneurysm. OBJECTIVE: To report our experience with recurrent cerebral aneurysms after neck clipping and to discuss classification and recommended management. METHODS: Aneurysm treatments from a single institution over a 20-year period were retrospectively reviewed. Twenty three recurrent aneurysms in 23 patients were managed during the study period. Recurrent aneurysms were classified using the concepts of closure line and closure plane, as follows. Type 1: neck situated in an almost different site from the previous clip. Type 2: existing closure plane and reconstructive closure plane are almost the same. Type 3: existing closure plane and reconstructive closure plane cross (type 3a); in rare cases, the existing closure line is sufficiently distant from the neck (type 3b). Type 4: no reconstructive closure line is identifiable. RESULTS: Nine patients presented with subarachnoid hemorrhage at recurrence. The mean interval to recurrence was 15.0 years. Management comprised clipping with elective subsequent old-clip removal (n = 7), clipping with preceding old-clip removal (n = 2), bypass occlusion (n = 1), coating (n = 1), combined surgery (n = 1), endovascular surgery (n = 4), and observation (n = 3). Therapeutic intervention was not indicated in 4 patients. Types 3a and 4 required more complex surgical procedures or coil embolization. Procedural complications were observed in 2 patients. CONCLUSION: A small but definite propensity toward recurrence after neck clipping exists, and most recurrent aneurysms require some form of retreatment. The novel classification scheme may provide conceptual clarity and therapeutic guidance for decision making. PMID- 29186596 TI - Long-Standing Scalp Retraction Technique Using an External Fixator for Sunken Skin Flap Syndrome. AB - BACKGROUND AND IMPORTANCE: The authors report a novel external scalp retraction technique for sunken skin flap syndrome (SSFS). CLINICAL PRESENTATION: A 48-year old male patient suffered neurological deterioration due to SSFS after decompressive craniectomy. Cranioplasty is the gold standard for therapeutic management of SSFS, but could not be performed due to intracranial wound infection. The patient underwent external fixation of a metal plate as a frame for the skull and the scalp was pulled outward to the frame by skin suture. The patient returned to daily activities at home for 3 months with this scalp traction frame, which was needed for infection control. CONCLUSION: External scalp traction is useful for the temporary relief of pressure caused by SSFS. PMID- 29186597 TI - Factors for a Good Surgical Outcome in Posterior Decompression and Dekyphotic Corrective Fusion with Instrumentation for Thoracic Ossification of the Posterior Longitudinal Ligament: Prospective Single-Center Study. AB - BACKGROUND: Surgery for thoracic ossification of the posterior longitudinal ligament (T-OPLL) is still challenging, and factors for good surgical outcomes are unknown. OBJECTIVE: To identify factors for good surgical outcomes with prospective and comparative study. METHODS: Seventy-one consecutive patients who underwent posterior decompression and instrumented fusion were divided into good or poor outcome groups based on >=50% and <50% recovery rates for the Japanese Orthopaedic Association score. Preoperative, intraoperative, and postoperative findings were compared in the 2 groups, and significant factors for a good outcome were analyzed. RESULTS: Patients with a good outcome (76%) had significantly lower nonambulatory rate and positive prone and supine position tests preoperatively; lower rates of T-OPLL, ossification of the ligamentum flavum, high-intensity area at the same level, thoracic spinal cord alignment difference, and spinal canal stenosis on preoperative magnetic resonance imaging; lower estimated blood loss; higher rates of intraoperative spinal cord floating and absence of deterioration of intraoperative neurophysiological monitoring; and lower rates of postoperative complications (P < .0005). In multivariate logistic regression analysis, negative prone and supine position test (odds ratio [OR]: 17.00), preoperative ambulatory status (OR: 6.05), absence of T-OPLL, ossification of the ligamentum flavum, high-intensity area at the same level (OR: 5.84), intraoperative spinal cord floating (OR: 4.98), and lower estimated blood loss (OR: 1.01) were significant factors for a good surgical outcome. CONCLUSION: This study demonstrated that early surgery is recommended during these positive factors. Appropriate surgical planning based on preoperative thoracic spinal cord alignment difference, as well as sufficient spinal cord decompression and reduction of complications using intraoperative ultrasonography and intraoperative neurophysiological monitoring, may improve surgical outcomes. PMID- 29186598 TI - Favorable Long-Term Functional Outcomes and Safety of Auditory Brainstem Implants in Nontumor Patients. AB - BACKGROUND: Auditory brainstem implants (ABIs) were designed to restore hearing in deaf patients with auditory tumors or those unable to receive cochlear implants. Although ABIs may help some patients, their long-term outcomes have been rarely studied. OBJECTIVE: To assess the long-term benefits and safety of ABIs in nontumor patients with sensorineural hearing loss (SNHL). METHODS: We retrospectively reviewed the histories of 15 deaf patients (8 females, 7 males; mean age, 15.5 yr; range, 1-56 yr) who received ABIs for treatment of SNHL at our hospital from July 2008 to November 2015. These included 11 children with narrow internal auditory canals and 4 deaf adults with severe cochlear ossification. In each patient, a 12-channel ABI electrode was placed in the cochlear nucleus complex via a retrosigmoid approach. Auditory performance was evaluated using the Categories of Auditory Performance (CAP) index and sound detection and word identification tests. RESULTS: One year after ABI placement, 13 of 15 patients showed adequate or significantly improved auditory function based on the CAP scores at the last follow-up. Generally, adult patients tended to show better CAP scores (3.50) than pediatric patients (2.15), but the difference was not significant (P = .058). Postoperative complications included electrode migration, cerebrospinal fluid leakage, nonauditory stimulation, and minor seizures without severe sequelae or mortality. CONCLUSION: ABIs show favorable functional outcomes and long-term safety in nontumor deaf patients with limited treatment options. Collectively, our data indicate that ABIs represent an important treatment option for SNHL. PMID- 29186599 TI - T-Connector Modification for Reducing Recurrent Distal Shunt Failure: Report of 2 Cases. AB - BACKGROUND AND IMPORTANCE: Cerebrospinal fluid shunt placement is used to treat the various causes of hydrocephalus by redirecting the cerebrospinal fluid to the body, most commonly from the ventricle to the peritoneum. Distal catheter displacement from the peritoneal cavity can occur as a complication, necessitating reoperation. CLINICAL PRESENTATION: We report 2 such cases in obese patients involving retropulsion of the distal tubing. To address this complication, we implanted a T-connector to the distal catheter construct. CONCLUSION: This study supports the use of a T-connector catheter construct to decrease and prevent the possibility of distal peritoneal catheter retropulsion in cases of elevated intra-abdominal pressure, both prophylactically and in revisions. PMID- 29186600 TI - An in Vitro Biomechanical Model of Differing Pedicle Screw Configurations for Long Construct Segmental Thoracic Fixation. AB - BACKGROUND: The optimum pattern of pedicle screw (PS) fixation during long segment thoracic fixation has not been determined. OBJECTIVE: To evaluate rod stress and construct stability with minimal, alternating, skipped, and bilateral PS constructs in the iatrogenically destabilized thoracic spine. METHODS: Eight cadaveric thoracic specimens (T3-T12) were initially tested intact to +/-5 Nm using a custom 6 degree-of-freedom spine testing apparatus in flexion-extension (FE), lateral bending (LB), and axial rotation. Specimens were instrumented with T4-T10 bilateral PS, with Ponte osteotomies to introduce instability. Rods were bent to fit the PS and then spines were tested with the minimal, alternating, skipped, and bilateral fixation patterns. Range of motion (ROM) was calculated from T4-T10 and segmentally. In addition, strain gauges fixed to the spinal rods measured rod stress under FE and LB. Results were compared using ANOVA and post hoc Holm Sidak tests. RESULTS: All fixation patterns provided significant reductions in ROM with respect to the intact spine. In all motion planes, minimal provided the least amount of rigidity, while bilateral provide the greatest; however, no statistically significant differences were detected in FE. In LB and axial rotation, skipped, alternating, and bilateral were all significantly more rigid than minimal (P < .01). Rod strains were greatest under LB and correlated with overall construct ROM, where bilateral had significantly lower strain than the other patterns (P < .05). CONCLUSION: All constructs effectively decreased thoracic ROM. There was significant improvement in stabilization and decreased rod stress when more fixation points beyond the minimal construct were included. PMID- 29186601 TI - Microsurgical Endoscope-Assisted Gravity-Aided Transfalcine Approach for Contralateral Metastatic Deep Medial Cortical Tumors. AB - BACKGROUND: Traditional approaches to deep medial cortical tumors utilize transcortical or ipislateral interhemispheric approaches, which can result in cortical damage or retraction injury. To reduce these risks, the microscopic transfalcine approach has been previously described. OBJECTIVE: To describe this approach performed with endoscopic assistance for metastatic tumor resection, demonstrating appropriate and safe tumor resection without injury to the contralateral hemisphere. METHODS: Eleven consecutive patients harboring medial, deep metastatic tumors are reported. Tumor resection was performed with endoscopic assistance with 2 surgeons. Clinical outcomes are recorded. RESULTS: All 11 patients underwent safe tumor resection. Gross total resection was achieved in 73% of patients. The application of the angled endoscope allowed for further tumor resection in 91% of patients. There were no complications in these patients. The contralateral brain did not demonstrate clinical or radiographic injury as well. CONCLUSION: This series suggests that the endoscopic transfalcine approach in the lateral position can be a safe and effective approach for resecting medial interhemispheric metastatic tumors. It allows excellent tumor visualization, eliminates the need for brain retraction, minimizes parenchymal transgression, and improves surgical ergonomics. A familiarity of endoscopy and neuroanesthesia support is helpful when utilizing this approach. PMID- 29186602 TI - Intraoperative Computed Tomography Angiography: A Novel Completion Imaging Modality for Carotid Endarterectomy. AB - BACKGROUND: Intraoperative computed tomography angiography (ICTA) is a novel completion imaging modality for carotid endarterectomy (CEA). No studies exist in the literature describing ICTA use in CEA. OBJECTIVE: To evaluate the feasibility and efficacy of ICTA as a method of immediately evaluating the technical results of CEA. METHODS: Twenty-three consecutive CEAs were performed by a single neurosurgeon over an 8-month period. Of this series, 12 utilized ICTA for completion imaging, 10 utilized duplex ultrasonography (US), and 1 utilized no intraoperative completion imaging. Electronic medical records were reviewed to assess demographics, CTA results, US results, and need for revisions. RESULTS: Patients included 13 men (62%) and 8 women (38%). All patients had symptomatic internal carotid artery stenosis. Polytetrafluoroethylene (PTFE) patch angioplasty was used in 16 cases (70%). Average operative times were comparable between cases that utilized CTA and US, 180 and 175 min, respectively. Major technical defects were identified in one of the 12 cases utilizing ICTA and none of the 10 cases utilizing intraoperative US. The technical defect was revised without subsequent neurological complication. One patient had a postoperative intracerebral hemorrhage requiring surgical evacuation. Fifteen patients were followed for up to 3 months with no postoperative stroke or transient ischemic attacks. CONCLUSION: ICTA is a potentially safe and effective completion imaging modality compared to traditional alternatives, enabling the identification of technical deficits intraoperatively. While no statistically significant difference in operative times were noted between intraoperative CTA and US use, numerous steps must be taken to maximize the efficiency of ICTA. PMID- 29186603 TI - Integrated Multimaneuver Dissection Technique of the Sylvian Fissure: Operative Nuances. AB - BACKGROUND: Several intracranial pathologies require opening the Sylvian fissure to be approached, and they are traditionally accessed through the frontal side of the superficial Sylvian veins. The integrated multimaneuver dissecting technique (IMMDT) interchanges the steps with the veins still secured for safe dissection, but the Sylvian fissure is approached from the optimal, safe side with integrated techniques. OBJECTIVE: To determine whether the 1-way dissection of the Sylvian fissure converts to the more favorable and flexible IMMDT. METHODS: The IMMDT for the Sylvian fissure was used on all our patients. The selected subjects (n = 3) had different pathologies, radiological data, and pre- and postoperative clinical data. These subjects were reviewed retrospectively. RESULTS: The 3 patients presented with different pathologies necessitating opening the Sylvian fissure. The Sylvian fissure was not simple in all cases. In all 3 cases, the Sylvian veins and their branches were saved, as confirmed by postoperative images. The patients all had good neurological outcomes, with either stable or improved modified Rankin Scale at the last follow-up. CONCLUSION: This study demonstrated that the IMMDT is a safe alternative to other ways of opening a Sylvian fissure composed of complex venous anatomy. The IMMDT aligned the fissure in multiple directions to the exposed trajectory, optimized its approach for a flexible, safe dissection, allowed the instruments to work into the Sylvian fissure, and facilitated exposure of the deep part of the fissure for the final dissection, all without scarifying any structure.

PMID- 29186606 TI - Technique of Minimally Invasive Cervical Foraminotomy. AB - BACKGROUND: Posterior cervical foraminotomy is a long utilized and commonly performed procedure, but has been supplanted in many cases by anterior procedures. With the advent of minimally invasive techniques, posterior foraminotomy may again deserve a prominent place in the treatment of cervical foraminal stenosis. OBJECTIVE: To report in detail a successfully utilized minimally invasive technique and the results in a large series of patients, by a single author. METHODS: The technique is described and illustrated in detail. A retrospective review of the use of this technique in a large series is reported. RESULTS: Precise details of the technique are described with specific attention to complication avoidance. In over 360 cases, there have been no nerve root injuries other than idiopathic C5 palsies, no wound infections, and a single durotomy that required no specific treatment. CONCLUSION: Minimally invasive posterior cervical foraminotomy is a well-tolerated and effective procedure which can be performed with minimal complications when attention to detail is maintained. PMID- 29186607 TI - Benefits and Limitations of Indocyanine Green Fluorescent Image-Guided Surgery for Spinal Intramedullary Tumors. AB - BACKGROUND: Intraoperative image guidance using near-infrared indocyanine green videoangiography (ICG-VA) has been used to provide real-time angiographic images during vascular or brain tumor surgery, and it is also being used for spine surgery. OBJECTIVE: To further investigate the benefits and limitations of ICG-VA image-guided surgery for spinal intramedullary tumors through retrospective study. METHODS: ICG-VA was used in 48 cases that were treated surgically over the past 5 yr. The pathological diagnoses of the tumors included astrocytic tumor, ependymal tumor, cavernous malformation, and hemangioblastoma. RESULTS: Localization of normal spinal arteries and veins on the dorsal surface of the spinal cord helped the surgeons determine the length or point of myelotomy. Well demarcated tumor stain was recognized in limited cases of anaplastic or highly vascularized tumors, whereas the location of cavernous malformation was recognized as an avascular area on the dorsal surface of the spinal cord. Feeding arteries and tumor stain were well differentiated from draining veins in dorsal hemangioblastomas, but not in intramedullary deep-seated or ventral tumors. The preservation of small perforating branches of the anterior spinal artery after successful resection of the tumor could be well visualized. CONCLUSION: ICG-VA can provide real-time information about vascular flow dynamics during the surgery of spinal intramedullary tumors, and it may help surgeons localize the normal circulation of the spinal cord, as well as the feeding arteries and draining veins, especially in highly vascular tumors. However, the benefits of intraoperative ICG-VA might be limited for intramedullary deep-seated or ventral tumors.

AB - Long-term, sustainable management of zebra chip disease of potato, caused by 'Candidatus Liberibacter solanacearum' (Lso) and vectored by potato psyllids (Bactericera cockerelli Sulc [Hemiptera: Triozidae]), requires development of cultivars resistant or tolerant to infection or capable of reducing spread or both. We examined the influence that five experimental breeding clones of potato had on potato psyllids and their ability to vector Lso. The ability of these potato clones to resist aphids (green peach aphids, Myzus persicae Sulzer [Hemiptera: Aphididae]) also was examined. Due to the importance of host chemistry on plant-insect interactions, levels of primary metabolites of amino acids and sugars, as well as secondary metabolites including polyphenolics, terpenoids, and alkaloids were compared between breeding clones and a commercial cultivar. Findings for compound levels then were associated with observed changes in host susceptibility to psyllids or aphids. Psyllids oviposited less on three breeding clones than Atlantic, but no significant effects of breeding clones on psyllid feeding or choice were observed. Aphid reproduction was reduced on two clones relative to Atlantic. A05379-211 had greater sugar levels and postpsyllid amino acid levels than Atlantic. Total alkaloid and phenolic levels were greater in all breeding clones than Atlantic. Total terpenoid levels were greater in PALB03016-3 and PALB03016-6 than Atlantic, which might explain, in part, the observed resistance to psyllid oviposition and aphid reproduction. Overall, these results suggest that increased levels of certain metabolites in breeding clones could affect psyllid and aphid reproduction.

PMID- 29186613 TI - Biochemical and structural characterization of a novel cooperative binding mode by Pit-1 with CATT repeats in the macrophage migration inhibitory factor promoter. AB - Overexpression of the proinflammatory cytokine macrophage migration inhibitory factor (MIF) is linked to a number of autoimmune diseases and cancer. MIF production has been correlated to the number of CATT repeats in a microsatellite region upstream of the MIF gene. We have characterized the interaction of pituitary-specific positive transcription factor 1 (Pit-1) with a portion of the MIF promoter region flanking a microsatellite polymorphism (-794 CATT5-8). Using fluorescence anisotropy, we quantified tight complex formation between Pit-1 and an oligonucleotide consisting of eight consecutive CATT repeats (8xCATT) with an apparent Kd of 35 nM. Using competition experiments we found a 23 base pair oligonucleotide with 4xCATT repeats to be the minimum DNA sequence necessary for high affinity interaction with Pit-1. The stoichiometry of the Pit-1 DNA interaction was determined to be 2:1 and binding is cooperative in nature. We subsequently structurally characterized the complex and discovered a completely novel binding mode for Pit-1 in contrast to previously described Pit-1 complex structures. The affinity of Pit-1 for the CATT target sequence was found to be highly dependent on cooperativity. This work lays the groundwork for understanding transcriptional regulation of MIF and pursuing Pit-1 as a therapeutic target to treat MIF-mediated inflammatory disorders. PMID- 29186616 TI - JUNB governs a feed-forward network of TGFbeta signaling that aggravates breast cancer invasion. AB - It is well established that transforming growth factor-beta (TGFbeta) switches its function from being a tumor suppressor to a tumor promoter during the course of tumorigenesis, which involves both cell-intrinsic and environment-mediated mechanisms. We are interested in breast cancer cells, in which SMAD mutations are rare and interactions between SMAD and other transcription factors define pro oncogenic events. Here, we have performed chromatin immunoprecipitation (ChIP) sequencing analyses which indicate that the genome-wide landscape of SMAD2/3 binding is altered after prolonged TGFbeta stimulation. De novo motif analyses of the SMAD2/3 binding regions predict enrichment of binding motifs for activator protein (AP)1 in addition to SMAD motifs. TGFbeta-induced expression of the AP1 component JUNB was required for expression of many late invasion-mediating genes, creating a feed-forward regulatory network. Moreover, we found that several components in the WNT pathway were enriched among the late TGFbeta-target genes, including the invasion-inducing WNT7 proteins. Consistently, overexpression of WNT7A or WNT7B enhanced and potentiated TGFbeta-induced breast cancer cell invasion, while inhibition of the WNT pathway reduced this process. Our study thereby helps to explain how accumulation of pro-oncogenic stimuli switches and stabilizes TGFbeta-induced cellular phenotypes of epithelial cells. PMID- 29186617 TI - POPULATION RADIATION EXPOSURE FROM DIAGNOSTIC NUCLEAR MEDICINE PROCEDURES IN TEHRAN 2011-14; TRENDS IN THE LAST 3 DECADES. AB - This study represents an update of Tehran population exposure from the diagnostic nuclear medicine procedures and the annual collective effective dose during 2011 14. The diagnostic nuclear medicine procedures data were collected from 58 out of 60 nuclear medicine centers in Tehran and were composed of the type and frequency of diagnostic examinations, radiopharmaceuticals used, administered activities, and age distribution of the patients. The annual number of examinations per 1000 population increased from 13.73 in 2011 to 22.59 in 2014 with an increase of 64.53% during 4 years. Most frequent examinations were cardiac (71.05%), bone (9.80%) and thyroid (7.26%) averaged over the 5 years. The collective effective dose increased from 807.74 person-Sv in 2011 to 1413.81 person-Sv in 2014. The effective dose per capita increased from 44.06 MUSv in 2011 to 120.91 MUSv in 2014, could be because of 70% increase of examinations, but ~3.42% increase in the population of Tehran. PMID- 29186618 TI - Semi-automatized segmentation method using image-based flow cytometry to study sperm physiology: the case of capacitation-induced tyrosine phosphorylation. AB - STUDY QUESTION: Is image-based flow cytometry a useful tool to study intracellular events in human sperm such as protein tyrosine phosphorylation or signaling processes? SUMMARY ANSWER: Image-based flow cytometry is a powerful tool to study intracellular events in a relevant number of sperm cells, which enables a robust statistical analysis providing spatial resolution in terms of the specific subcellular localization of the labeling. WHAT IS KNOWN ALREADY: Sperm capacitation is required for fertilization. During this process, spermatozoa undergo numerous physiological changes, via activation of different signaling pathways, which are not completely understood. Classical approaches for studying sperm physiology include conventional microscopy, flow cytometry and Western blotting. These techniques present disadvantages for obtaining detailed subcellular information of signaling pathways in a relevant number of cells. This work describes a new semi-automatized analysis using image-based flow cytometry which enables the study, at the subcellular and population levels, of different sperm parameters associated with signaling. The increase in protein tyrosine phosphorylation during capacitation is presented as an example. STUDY DESIGN SIZE, DURATION: Sperm cells were isolated from seminal plasma by the swim-up technique. We evaluated the intensity and distribution of protein tyrosine phosphorylation in sperm incubated in non-capacitation and capacitation supporting media for 1 and 18 h under different experimental conditions. We used an antibody against FER kinase and pharmacological inhibitors in an attempt to identify the kinases involved in protein tyrosine phosphorylation during human sperm capacitation. PARTICIPANTS/MATERIALS, SETTING, METHODS: Semen samples from normospermic donors were obtained by masturbation after 2-3 days of sexual abstinence. We used the innovative technique image-based flow cytometry and image analysis tools to segment individual images of spermatozoa. We evaluated and quantified the regions of sperm where protein tyrosine phosphorylation takes place at the subcellular level in a large number of cells. We also used immunocytochemistry and Western blot analysis. Independent experiments were performed with semen samples from seven different donors. MAIN RESULTS AND THE ROLE OF CHANCE: Using image analysis tools, we developed a completely novel semi automatic strategy useful for segmenting thousands of individual cell images obtained using image-based flow cytometry. Contrary to immunofluorescence which relies on the analysis of a limited sperm population and also on the observer, image-based flow cytometry allows for unbiased quantification and simultaneous localization of post-translational changes in an extended sperm population. Interestingly, important data can be independently analyzed by looking to the frame of interest. As an example, we evaluated the capacitation-associated increase in tyrosine phosphorylation in sperm incubated in non-capacitation and capacitation-supporting media for 1 and 18 h. As previously reported, protein tyrosine phosphorylation increases in a time-depending manner, but our method revealed that this increase occurs differentially among distinct sperm segments. FER kinase is reported to be the enzyme responsible for the increase in protein tyrosine phosphorylation in mouse sperm. Our Western blot analysis revealed for the first time the presence of this enzyme in human sperm. Using our segmentation strategy, we aimed to quantify the effect of pharmacological inhibition of FER kinase and found a marked reduction of protein tyrosine phosphorylation only in the flagellum, which corresponded to the physical localization of FER in human sperm. Our method provides an alternative strategy to study signaling markers associated with capacitation, such as protein tyrosine phosphorylation, in a fast and quantitative manner. LARGE SCALE DATA: None. LIMITATIONS REASONS FOR CAUTION: This is an in vitro study performed under controlled conditions. Chemical inhibitors are not completely specific for the intended target; the possibility of side effects cannot be discarded. WIDER IMPLICATIONS OF THE FINDINGS: Our results demonstrate that the use of image-based flow cytometry is a very powerful tool to study sperm physiology. A large number of cells can be easily analyzed and information at the subcellular level can be obtained. As the segmentation process works with bright-field images, it can be extended to study expression of other proteins of interest using different antibodies or it can be used in living sperm to study intracellular parameters that can be followed using fluorescent dyes sensitive to the parameter of interest (e.g. pH, Ca2+). Therefore, this a versatile method that can be exploited to study several aspects of sperm physiology. STUDY FUNDING AND COMPETING INTEREST(S): This work was supported DGAPA (IN203116 to C.

PMID- 29186619 TI - Multisite Machine Learning Analysis Provides a Robust Structural Imaging Signature of Schizophrenia Detectable Across Diverse Patient Populations and Within Individuals. AB - Past work on relatively small, single-site studies using regional volumetry, and more recently machine learning methods, has shown that widespread structural brain abnormalities are prominent in schizophrenia. However, to be clinically useful, structural imaging biomarkers must integrate high-dimensional data and provide reproducible results across clinical populations and on an individual person basis. Using advanced multi-variate analysis tools and pooled data from case-control imaging studies conducted at 5 sites (941 adult participants, including 440 patients with schizophrenia), a neuroanatomical signature of patients with schizophrenia was found, and its robustness and reproducibility across sites, populations, and scanners, was established for single-patient classification. Analyses were conducted at multiple scales, including regional volumes, voxelwise measures, and complex distributed patterns. Single-subject classification was tested for single-site, pooled-site, and leave-site-out generalizability. Regional and voxelwise analyses revealed a pattern of widespread reduced regional gray matter volume, particularly in the medial prefrontal, temporolimbic and peri-Sylvian cortex, along with ventricular and pallidum enlargement. Multivariate classification using pooled data achieved a cross-validated prediction accuracy of 76% (AUC = 0.84). Critically, the leave site-out validation of the detected schizophrenia signature showed accuracy/AUC range of 72-77%/0.73-0.91, suggesting a robust generalizability across sites and patient cohorts. Finally, individualized patient classifications displayed significant correlations with clinical measures of negative, but not positive, symptoms. Taken together, these results emphasize the potential for structural neuroimaging data to provide a robust and reproducible imaging signature of schizophrenia. A web-accessible portal is offered to allow the community to obtain individualized classifications of magnetic resonance imaging scans using the methods described herein.

AB - Diesel exhaust (DE) as the major source of vehicle-emitted particle matter in ambient air impairs lung function. The objectives were to assess the contribution of local (eg, the fraction of exhaled nitric oxide [FeNO] and serum Club cell secretory protein [CC16]) and systemic (eg, serum C-reaction protein [CRP] and interleukin-6 [IL-6]) inflammation to DE-induced lung function impairment using a unique cohort of diesel engine testers (DETs, n = 137) and non-DETs (n = 127), made up of current and noncurrent smokers. Urinary metabolites, FeNO, serum markers, and spirometry were assessed. A 19% reduction in CC16 and a 94% increase in CRP were identified in DETs compared with non-DETs (all p values <10-4), which were further corroborated by showing a dose-response relationship with internal dose for DE exposure (all p values <.04) and a time-course relationship with DE exposure history (all p values <.005). Mediation analysis showed that 43% of the difference in FEV1 between DETs and non-DETs can be explained by circulating CC16 and CRP (permuted p < .001). An inverse dose-dependent relationship between FeNO and internal dose for cigarette smoke was identified (p = .0003). A range of 95% lower bounds of benchmark dose of 1.0261-1.4513 MUg phenanthrols/g creatinine in urine as an internal dose was recommended for regulatory risk assessment. Local and systemic inflammation may be key processes that contribute to the subsequent development of obstructive lung disease in DE-exposed populations. PMID- 29186623 TI - Developmental origins of health and disease: current knowledge and potential mechanisms. AB - Epidemiologic and clinical research has provided a large body of evidence supporting the developmental origins of health and disease (DOHaD), but there has been a relative dearth of mechanistic studies in humans due to the complexity of working with large, longitudinal cohorts. Nonetheless, animal models of undernutrition have provided substantial evidence for the potential epigenetic, metabolic, and endocrine mechanisms behind DOHaD. Furthermore, recent research has explored the interaction between the environment and the gastrointestinal system by investigating how the gut microbial ecology may impact the capacity for nutrient processing and absorption in a manner that may limit growth. This review presents a summary of current research that supports the concept of DOHaD, as well as potential mechanisms and interactions that explain how nutrition in utero and during early childhood influences lifelong health. PMID- 29186625 TI - Lesbian Motherhood and the Artificial Insemination by Donor Scandal of 1978. AB - In January 1978, the London Evening News informed its readers of its shocking discovery that British lesbians were conceiving babies by artificial insemination by donor (AID). Assisted by a respected London gynaecologist, Dr David Sopher, the women were planning and raising children in the context of lesbian relationships, challenging conventional family models and the widespread presumption that lesbianism and motherhood were mutually exclusive identities. The debate which was sparked by the Evening News expose and taken up in Parliament, the national and local media and on the streets in the subsequent weeks, offers an insight into attitudes towards lesbian motherhood in the late 1970s. This article explores constructions of lesbian mothers and the impact on the experiences and identities of lesbian mothers themselves. The late 1970s marked the beginnings of a shift in practices of conception by British lesbians from lesbians who conceived their children in the context of previous heterosexual relationships, to women who utilized AID and other forms of donor insemination to forge new family structures, and this article analyses the stories of some of these women as they emerged from the 1978 debate. PMID- 29186626 TI - Contested Spaces: London and the 1984-5 Miners' Strike. AB - The 1984-5 British miners' strike can be understood as a defence of place as well as jobs. Such a conception encourages us to foreground the local in accounts of the strike. However, I argue in this article that the local should not be understood in an excessively bounded way. By paying attention to relationships developed between London and the coalfields during the dispute, we can see how direct personal networks of solidarity were constructed between these very different places. This article discusses the spaces in which solidarity activity for miners in London took place. I argue that political activists rooted themselves in localities by constructing permanent spaces such as centres and bookshops, which enabled the development of concrete relationships between different places. I highlight 'twinning' as a distinct spatial tactic used by supporters of the strike to bridge geographical distance and develop personal connections between London and the coalfields. I also show that elements of the state were used to both sustain this solidarity and to restrict the space available for the miners and their supporters. I argue centrally, therefore, that opposing political visions for moving beyond the post-war settlement manifested in a struggle over space in the 1980s.

AB - This meta-analysis compares the brain structures and mechanisms involved in facial and vocal emotion recognition. Neuroimaging studies contrasting emotional with neutral (face: N = 76, voice: N = 34) and explicit with implicit emotion processing (face: N = 27, voice: N = 20) were collected to shed light on stimulus and goal-driven mechanisms, respectively. Activation likelihood estimations were conducted on the full data sets for the separate modalities and on reduced, modality-matched data sets for modality comparison. Stimulus-driven emotion processing engaged large networks with significant modality differences in the superior temporal (voice-specific) and the medial temporal (face-specific) cortex. Goal-driven processing was associated with only a small cluster in the dorsomedial prefrontal cortex for voices but not faces. Neither stimulus- nor goal-driven processing showed significant modality overlap. Together, these findings suggest that stimulus-driven processes shape activity in the social brain more powerfully than goal-driven processes in both the visual and the auditory domains. Yet, whereas faces emphasize subcortical emotional and mnemonic mechanisms, voices emphasize cortical mechanisms associated with perception and effortful stimulus evaluation (e.g. via subvocalization). These differences may be due to sensory stimulus properties and highlight the need for a modality specific perspective when modeling emotion processing in the brain.

AB - Research on folk culture in twentieth-century Britain has focused on elite and transgressive political episodes, but these were not its mainstream manifestations. This article re-evaluates the place of folk culture in twentieth century Britain in the context of museums. It argues that in the modern heritage landscape folk culture was in an active dialogue with the modern democracy. This story begins with the vexed, and ultimately failed, campaign for a national English folk museum and is traced through the concurrent successes of local, regional, and Celtic 'first wave' folk museums across Britain from the 1920s to the 1960s. The educational activities of these museums are explored as emblematic of a 'conservative modernity', which gave opportunities to women but also restricted their capacity to do intellectual work. By the 1970s, a 'second wave' folk museology is identified, revealing how forms of folk culture successfully accommodated the rapid social change of the later twentieth century, particularly in deindustrializing regions. From this new, museums' perspective, folk culture appears far less marginal to twentieth-century British society. In museums folk culture interacted with mainstream concerns about education, regionalism, and commercialization. PMID- 29186628 TI - The Complex Holiday Calendar of 1902: Responses to the Coronation of Edward VII and the Growth of Edwardian Event Fatigue. AB - The coronation of Edward VII and events to mark the end of the South African War led to a series of public ceremonies and events in the United Kingdom that had a profound effect on attitudes linked to national occasions and public holidays. This article explores the circumstances surrounding the numerous local and national holidays of 1902. It considers the decision-making process linked to the declaration of a coronation double-bank holiday, which demonstrated the inadequacy of contemporary legislation. The public response to the postponement of the coronation, due to the king's contraction of appendicitis, led to a period of 'event fatigue' in response to further ceremonial events. This showcased how much the British people guarded their right to holiday time and how the coronation had become more synonymous with celebration than with royal ceremony. It also showcased the degree to which the British people had been politicized and were ready to defend what they saw as their rights, in rejection of deference and traditional authority.

AB - Aberrant rule- and reward-based processes underpin abnormalities of socio emotional behaviour in major dementias. However, these processes remain poorly characterized. Here we used music to probe rule decoding and reward valuation in patients with frontotemporal dementia (FTD) syndromes and Alzheimer's disease (AD) relative to healthy age-matched individuals. We created short melodies that were either harmonically resolved ('finished') or unresolved ('unfinished'); the task was to classify each melody as finished or unfinished (rule processing) and rate its subjective pleasantness (reward valuation). Results were adjusted for elementary pitch and executive processing; neuroanatomical correlates were assessed using voxel-based morphometry. Relative to healthy older controls, patients with behavioural variant FTD showed impairments of both musical rule decoding and reward valuation, while patients with semantic dementia showed impaired reward valuation but intact rule decoding, patients with AD showed impaired rule decoding but intact reward valuation and patients with progressive non-fluent aphasia performed comparably to healthy controls. Grey matter associations with task performance were identified in anterior temporal, medial and lateral orbitofrontal cortices, previously implicated in computing diverse biological and non-biological rules and rewards. The processing of musical rules and reward distils cognitive and neuroanatomical mechanisms relevant to complex socio-emotional dysfunction in major dementias. PMID- 29186632 TI - Integrating sequence and gene expression information predicts genome-wide DNA binding proteins and suggests a cooperative mechanism. AB - DNA-binding proteins (DBPs) perform diverse biological functions ranging from transcription to pathogen sensing. Machine learning methods can not only identify DBPs de novo but also provide insights into their DNA-recognition dynamics. However, it remains unclear whether available methods that can accurately predict DNA-binding sites in known DBPs can also identify novel DBPs. Moreover, sequence information is blind to the cellular- and disease-specific contexts of DBP activities, whereas the under-utilized knowledge from public gene expression data offers great promise. To address these issues, we have developed novel methods for predicting DBPs by integrating sequence and gene expression-derived features and applied them to explore human, mouse and Arabidopsis proteomes. While our sequence-based models outperformed the gene expression-based ones, some proteins with weaker DBP-like sequence features were correctly predicted by gene expression-based features, suggesting that these proteins acquire a tangible DBP functionality in a conducive gene expression environment. Analysis of motif enrichment among the co-expressed genes of top 100 candidates DBPs from hitherto unannotated genes provides further avenues to explore their functional associations. PMID- 29186634 TI - A Model to Integrate Health Promotion and Wellness in Physical Therapist Practice: Development and Validation. AB - Background: Globally, physical therapy professional organizations have called for physical therapists to perform lifestyle behavior management during customary care, or health-focused care, due to increasing morbidity and mortality related to noncommunicable diseases. Given the potential for health-focused care to improve health outcomes, physical therapists should integrate health promotion into their daily clinical practice. A clinical model that illustrates necessary steps to deliver health-focused care would be helpful to educate present and future physical therapists. Objective: The purpose of the study was to develop and validate the Health-Focused Physical Therapy Model (HFPTM) for physical inactivity and smoking. Methods: The authors used a mixed method approach. The preliminary model was informed by previous research and the investigators' shared experience in health promotion and physical therapy. An interdisciplinary group of health professionals provided input into the preliminary model by way of a World Cafe format. Eight physical therapists with health promotion and education expertise then engaged in a Delphi process to establish content validity. Results: World Cafe participants indicated that: (1) physical therapists are well positioned to engage in health promotion and wellness, and (2) the model facilitates interdisciplinary collaboration and consultation. Delphi process participants reached majority consensus in 1 round. The average model content validity index (CVI) was .915 for physical inactivity and .899 for smoking. Agreement concerning the model schematic was 88% for either behavior. Investigators made few editorial changes after the Delphi process. Limitations: Limitations of this study include using only 2 unhealthy lifestyle behaviors for testing, and performing the testing in a nonclinical setting. Conclusions: An interdisciplinary group of health professionals believes that physical therapists should practice health-focused care and that the HFPTM is a valid model. This model could help physical therapist educators when educating physical therapist students and clinicians to practice health-focused care. PMID- 29186633 TI - Family-centered Care Improved Neonatal Medical and Neurobehavioral Outcomes in Preterm Infants: Randomized Controlled Trial. AB - Background: Family-centered care for preterm infants in Western societies has yielded short- to medium-term benefits. However, the intervention effects have rarely been validated in Eastern societies. Objective: The aim of this study was to examine whether a family-centered intervention program (FCIP) could improve the short-term medical and neurobehavioral outcomes in preterm infants with very low birth weight (VLBW; a birth weight of <1,500 g) in Taiwan over the outcomes seen with a usual care program (UCP). Design: This was a multicenter, single blind, randomized controlled trial study. Setting: Three medical centers in northern and southern Taiwan were the locations for the study. Participants: The participants were 251 VLBW preterm infants without severe perinatal complications. Intervention: The infants were randomly assigned to receive the FCIP or the UCP during hospitalization. Measurements: Infant morbidities, feeding, growth, and neurobehavioral performance were evaluated during the neonatal period. Parental adherence to interventions was measured in the FCIP group. Results: The FCIP promoted earlier full enteral feeding (beta = -1.1 weeks; 95% CI = -1.9 to -0.2 weeks) and hospital discharge (beta = -0.6 week; 95% CI = -1.1 to -0.1 weeks), greater weight gain (beta = 3.3 g/d; 95% CI = 0.1 to 6.6 g/d), and better neurobehavioral performance than the UCP (beta = 1.2 points; 95% CI = 0.2 to 2.3 points). Furthermore, a higher degree of parental motivation in interventions, goal attainment, and comprehensiveness of home activities was significantly associated with greater effects in infants' neurobehavioral performance and weight gain (r = .20-.31; all Ps < .05). Limitations: The findings may not be generalized to preterm infants with severe perinatal diseases and parents with a low level of interest in interventions. Conclusions: Family centered care facilitated short-term medical and neurobehavioral outcomes in VLBW preterm infants in Taiwan; the effects were likely achieved through parental adherence to interventions. The designated strategies may be considered in a future launch of family-centered care in Taiwan. PMID- 29186636 TI - A New Breed of Rehabilitation Scientists. PMID- 29186635 TI - Identification of Indirect Effects in a Cognitive Patient Education (COPE) Intervention for Low Back Pain. AB - Background: Many interventions for the treatment of low back pain exist, but the mechanisms through which such treatments work are not always clear. This situation is especially true for biopsychosocial interventions that incorporate several different components and methods of delivery. Objective: The study objective was to examine the indirect effects of the Cognitive Patient Education (COPE) intervention via illness perceptions, back pain myths, and pain catastrophizing on disability outcome. Design: This study was a secondary analysis of the COPE randomized controlled trial. Methods: Mediation analysis techniques were employed to examine the indirect effects of the COPE intervention via residualized change (baseline - posttreatment) in the 3 variables hypothesized to be targeted by the COPE intervention on posttreatment disability outcome. Pain intensity at baseline, pain duration, clinician type, and a treatment-mediator interaction term were controlled for in the analysis. Results: Preliminary analyses confirmed that changes in pain catastrophizing and illness perceptions (not back pain myths) were related to both allocation to the intervention arm and posttreatment disability score. The treatment exerted statistically significant indirect effects via changes in illness perceptions and pain catastrophizing on posttreatment disability score (illness perceptions standardized indirect effect = 0.09 [95% CI = 0.03 to 0.16]; pain catastrophizing standardized indirect effect = 0.05 [95% CI = 0.01 to 0.12]). However, the inclusion of an interaction term led to the indirect effects being significantly reduced, with the effects no longer being statistically significant. Limitations: This study presents a secondary analysis of variables not identified a priori as being potentially important treatment targets; other, unmeasured factors could also be important in explaining treatment effects. Conclusions: The finding that small indirect effects of the COPE intervention via changes in illness perceptions and pain catastrophizing on posttreatment disability could be estimated indicates that these variables may be viable treatment targets for biopsychosocial interventions; however, this finding must be viewed in light of the adjusted analyses, which showed that the indirect effects were significantly reduced through the inclusion of a treatment-mediator interaction term. PMID- 29186637 TI - Factors associated with upper leg muscle strength in knee osteoarthritis: A scoping review. AB - OBJECTIVE: Muscle weakness is common and strongly related to clinical outcome in patients with knee or hip osteoarthritis. To date, there is no clear overview of the information on factors associated with muscle strength in knee and hip osteoarthritis. The aim of this paper is to provide an overview of current knowledge on factors associated with upper leg muscle strength in this population. DESIGN: The framework of a scoping review was chosen. MEDLINE database was searched systematically up to 22 April 2017. Studies that described a relationship between a factor and muscle strength in knee or hip osteoarthritis were included. RESULTS: A total of 65 studies met the inclusion criteria. In studies of knee osteoarthritis, 4 factors were consistently found to be associated with lower muscle strength. Due to the low number of studies on hip osteoarthritis no conclusions could be drawn on associations. CONCLUSION: Lower muscle quality, physical inactivity, more severe joint degeneration, and higher pain are reported to be associated with lower strength in the upper leg muscles in knee osteoarthritis. Future research into knee osteoarthritis should focus on other potential determinants of muscle strength, such as muscle quantity, muscle activation, nutrition and vitamins, and inflammation. In hip osteoarthritis, more research is needed into all potential determinants. PMID- 29186638 TI - Stent-over-sponge (SOS): a novel technique complementing endosponge therapy for foregut leaks and perforations. AB - BACKGROUND AND STUDY AIMS: Endoluminal vacuum therapy (EVT) has evolved as a promising option for endoscopic treatment of foregut wall injuries in addition to the classic closure techniques using clips or stents. To improve vacuum force and maintain esophageal passage, we combined endosponge treatment with a partially covered self-expandable metal stent (stent-over-sponge; SOS). PATIENTS AND METHODS: Twelve patients with infected upper gastrointestinal wall defects were treated with the SOS technique. RESULTS: Indications for SOS were anastomotic leakage after surgery (n = 11) and chronic foregut fistula (n = 1). SOS treatment was used as a first-line treatment in seven patients with a success rate of 71.4 % (5/7) and as a second-line treatment after failed previous EVT treatment in five patients (success rate 80 %; 4/5). Overall, SOS treatment was successful in 75 % of patients (9/12). No severe adverse events occurred. CONCLUSION : SOS is an effective method to treat severely infected foregut wall defects in patients where EVT has failed, and also as a first-line treatment. Comparative prospective studies are needed to confirm our preliminary results. PMID- 29186639 TI - Interferon-free cure of chronic Hepatitis C is associated with weight gain during long-term follow-up. AB - Background and aim The advent of direct-acting antivirals has revolutionized treatment of chronic hepatitis C with very high cure rates and excellent tolerability compared to interferon-based hepatitis C virus (HCV) treatment. However, long-term effects of interferon-free cure of HCV infection on the metabolic condition of patients have not been investigated so far. Methods We investigated weight development during and after antiviral treatment of hepatitis C. In a prospective single-center cohort study, interferon-free antiviral treatment was initiated in 284 patients. Each patient's weight was monitored 1 year before the start of treatment, at baseline (BL), end of treatment (EOT), follow-up week 24 (FU24), and follow-up week 48 (FU48). Results Weight gain after HCV cure was observed in 20 %, 33 %, and 44 % of patients at EOT, FU24, and FU48, respectively. The mean overall weight change at FU48 compared to baseline was 1.45 kg (95 % CI 0.44; 2.46, p = 0.02, compared to the pretreatment period). Multivariate regression revealed age as the only factor predicting weight change at FU48 (B - 0.107, 95 % CI, - 0.202 to - 0.011, p = 0.03), while gender, cirrhosis, diabetes mellitus, ribavirin, and body mass index had no influence. In the subgroup of patients younger than 60 years, mean weight gain at FU48 compared to baseline was 2.8 kg (95 % CI, 1.23 - 4.4). In contrast, patients 60 years and older had a mean weight change of - 0.04 kg (95 % CI, - 1.12 to 1.03, p = 0.005). Conclusions Cure of HCV by interferon-free antiviral treatment was associated with weight gain in up to 44 % of patients during long-term follow-up. Weight gain occurred predominantly in patients younger than 60 years. The precise mechanism of weight gain remains to be elucidated. PMID- 29186640 TI - [Esomeprazol-induced cutaneous lupus erythematosus]. AB - Proton pump inhibitors are among the most commonly used drugs worldwide. They are considered to be largely safe and cause little side-effects. We report a 69-year old woman who suffered from erythematous plaques 2 months after initiating therapy with esomeprazole. The diagnosis of subacute cutaneous lupus erythematosus was based on the clinical picture together with characteristic histological features of a skin biopsy specimen and the detection of anti-Ro/SSA antibodies. In particular, the temporal relationship with the onset of proton pump inhibitor therapy led to the high-level suspicion of a drug-induced pathogenesis. Strengthening the initially suspected diagnosis, the characteristic skin lesions resolved almost completely without specific therapy after discontinuation of the medication. If typical skin lesions occur in light-exposed areas in connection with the administration of PPI, the possibility of a drug induced cutaneous lupus erythematosus should always be considered. Due to the frequent recurrence rate after renewed exposure, a new therapy with PPI should be avoided. PMID- 29186641 TI - Gut microbiota and colorectal cancer: insights into pathogenesis for novel therapeutic strategies. AB - Colorectal cancer (CRC), as a leading cause of cancer-related death, is triggered by the complex interplay of host genetics and environmental factors. Mounting evidence has shed light on the association of the gut microbiota dysbiosis with CRC. In CRC experimental models, certain gut microbial strains have been shown to inhibit or attenuate immune responses, indicating that specific species among intestinal commensal bacteria may play either a pathogenic or a protective role in the development of CRC. Oral intake of probiotics/prebiotics can therefore serve as a therapeutic approach for CRC treatment. Microbiota studies in cancer, however, are still at the early stage, lack of quantitative data for clinic application. Fortunately, sequencing-based technologies are a boon to further investigation on the association of the intestinal bacterial flora and human diseases. This review considers the evidence for the role of the gut microbiota in CRC development and progression, responsiveness to immune system, and the related therapeutic applications of probiotics/prebiotics.

AB - BACKGROUND: The leadership style of the head nurses plays a crucial role in ensuring a work environment that fosters high quality nursing care. Their role involves a range of activities that constantly change, and is therefore difficult to describe. In fact, we do not have a fixed set of characteristics to define the 'ideal candidate'. AIM: To understand how staff defines the key leadership characteristics of the ideal head nurse in charge of a hospital ward. METHOD: Between April-July 2015, 27 nurses were selected from the departments of general medicine in five hospitals. Three focus groups were conducted to identify the key leadership characteristics of an ideal head nurse. RESULTS: The ideal leadership characteristics are expressed through actions of staff empowerment, management skills, and use of coping strategies. All these categories require that a leader should be strongly determined, resourceful, enthusiastic, and willing to be a leader. When balancing 'what you give and receive', the main difficulty of being a leader is to be sufficiently determined to avoid exhaustion, which leads to emotional disengagement and consequently the loss of the leadership role. CONCLUSIONS: The level of determination of a head nurse, just like any source of energy, may sway. Therefore, it is important to recognize the signs of exhaustion and identify the strategy to rekindle determination. Sharing one's vision with others and job rotation could be used as strategies to recharge a leader's levels of energy, and meet the expectations linked to the leader's role. KEY WORDS: nurse manager, leadership style, determination, job rotation, vision.

METHOD: The study follows a qualitative descriptive method. Data have been collected through focus groups (FGs). We have organized four different FGs, a specific focus group for each stakeholder (students, nurses and tutors) and a closing one with everybody. Each FG followed a qualitative content analysis method. Students had to fill in the CLES+T questionnaire to confirm qualitative data. RESULTS: Participants: 6 tutors, 7 nurses and 10 students (i.e. 6 first-year, 2 second-year and 2 third-year students). The experience has been positive. We have found four different themes, both cross-sectional and specific, in relation to positive aspects. 1. Briefing and debriefing as discussion and learning opportunities (cross-sectional); 2. Peer education potentialities (cross-sectional); 3. Global and holistic care (students); 4. Academic tutors as ward resources (cross-sectional). In relation to critical aspects, instead, we have highlighted a macro-theme, which refers to "Organizational peculiarities" and is composed of three subthemes: 1. Workload (tutors and nurses); 2. Inhomogeneity in nurses and tutors' behaviour/attitude (cross-sectional); 3. Lack of a personal relationship between students and training assistants (students). All the ameliorative proposals are related to organizational peculiarities. CONCLUSION: This study reports the first Italian experimentation of the DEU training organization model. The experience has been very positive: it has not only promoted a moment's reflection but also provided the opportunity for both the Clinical and the Academic setting to discuss and collaborate to reach the common goal, i.e. best student learning. PMID- 29186648 TI - [Is repositioning regimen effective to prevent pressure injuries? Synopsis of systematic reviews.] AB - INTRODUCTION: Repositioning regimen is an intervention recommended by guidelines and traditionally used in daily care practice but its benefit for preventing pressure injuries (PI) is not clinically proved. OBJECTIVE: To determine the effect of repositioning regimen to prevent PI. METHODS: A research on five electronic databases (The Cochrane Library, Medline, Embase, CINAHL, Web of Science) was conducted on March 23, 2017. Records returned by the search strategy were independently analyzed and those that respected inclusion criteria have been found in full text. In synopsis have been included systematic reviews of controlled clinical trials or quasi-experimental studies that compare repositioning regimen with usual care. The AMSTAR checklist has been used for quality evaluation. RESULTS: Five systematic reviews met inclusion criteria. The methodological quality of included studies have been very heterogeneous. Compared to usual cares, intervention is not associated with a statistically significant reduction of PI. DISCUSSION: A few and small available studies do not allow to ascertain a benefit from the intervention, if any. At the moment, the application of an individualized repositioning regimen seems a reasonable solution. Further researches are needed to confirm that a more frequent repositioning and a 30 degrees lateral decubitus intake help to prevent PI. It is also necessary to evaluate the economic impact, the acceptability and risks associated with the intervention. CONCLUSION: It is still unclear the role of repositioning regimen to prevent PI. PMID- 29186649 TI - [Unidimensional scales for dementia: a cross-sectional study in elderly Italian retirement houses residents]. AB - BACKGROUND: The pain in instituzionalized elderly people with cognitive impairment is common. This symptom is severely under-reported and under-treated within this population. Evaluation of pain intensity is an essential component of pain assessment. Self-report approach to pain assessment is generally regarded as the gold standard of pain measurement in people with mild and moderate cognitive decay. The literature demonstrated more different unidimensional self-report scales but the conclusions of the studies suggested often the utilization of different scales. AIM: The goal of this study was to compare three different unidimensional pain assessment scales to be used with 84 instituzionalized elderly people with an average Mini-Mental State Examination score of 18. METHOD: This was a descriptive cross-sectional study. The pain assessment was carried out by administering the three scales Faces Pain Scale (FPS), Numeric Rating Scale (NRS), Verbal Rating Scale (VRS). RESULTS: The results showed that the prevalence of pain was 60-70%. All three pain intensity scales had good reliability and validity (p=0.0001); The compilation time of Faces Pain Scale most above than the other two scales (p=0.0001). CONCLUSION: The findings of this article support the implementation of these scales in operative protocols considering the compilation time and preferences of the patients. PMID- 29186650 TI - [Survey of secondary school students 18 years old or older about knowledge on risks to the fetus related to alcohol consumption during pregnancy]. AB - INTRODUCTION: Being not perceived as risky for health, alcohol consumption is socially accepted worldwide. Nevertheless, related risks for the fetus are relevant, even for occasional use. In Italy there is a high consumption of alcohol among young people and pregnant women, and an increasing number of children born with alcohol-related disorders. AIM: To investigate the knowledge on fetal alcohol-related disorders among students over 18 years of age in a regional capital in the North of Italy. METHODS: In May, 2015, a survey with an online, validated questionnaire was conducted on N=1321 students. RESULTS: A total of N=246 valid questionnaires was obtained (18,6%). The 76,4% of students knew that drinking alcohol during pregnancy damages fetus, but only the 23,5% knew that this damages are permanent. Only the 43,5% knew that this damages are preventable; of them, the 77,6% stated that the only way to prevent them is abstention from alcohol consumption, though 30,1% answered that alcohol use is allowed without damage the fetus. Only the 17,5% answered to know Fetal Alcohol Spectrum Disorders. CONCLUSION: The study showed satisfying knowledge on general aspects, but scarce on specific ones, and a limited awareness that only complete abstinence from alcohol when pregnant can prevent irreversible damages of the fetus. This results could help to program educational interventions for teenagers, carried out by nurses, pediatric nurses and other health professionals to increase their knowledge and prevent in utero exposure. Future studies could be aimed at identifying the most effective educational methods to do so. PMID- 29186651 TI - Lived experience of patients with glaucoma glaucoma: a phenomenological study. AB - INTRODUCTION: Glaucoma is often a misdiagnosed pathology and is one of the main causes of blindness in the world population.Glaucoma frequentlycauses limitations in theactivities of daily livingand changes the patient's quality of life. AIM: The purpose of our study is to describe the life experiences of subjects in southern Italy suffering from glaucoma. METHOD: Phenomenological study RESULTS: From the analysis of interviews six main themes emerged:(1) a profound change in lifestyle, (2) casual diagnosis,(3) independent research,(4) fear of blindness,(5) fear of being a burden to family, and (6) fear of familial pathology. Two additional themes appeared: the subjects felt lucky not to have a deadly disease and were uncertain about the future. CONCLUSION: The negative aspects prevail over any positive facets. A deep understanding of these experiences can help health care professionals to deliver correct holistic support. PMID- 29186652 TI - Combination of Obestatin and Bone Marrow Mesenchymal Stem Cells Prevents Aggravation of Endocrine Pancreatic Damage in Type II Diabetic Rats. AB - One of the new promising therapies in treatment of diabetes mellitus is mesenchymal stem cells (MSCs) which have an interesting therapeutic potentiality based on their paracrine effect and transdifferentiation potentiality. Also obestatin improves the generation of functional beta cells/islet-like cell clusters in vitro, suggesting implications for cell-based replacement therapy in diabetes. So the aim of this study was to evaluate the effect of combination of both MSCs and obestatin on an experimental model of type II diabetes mellitus (T2DM). Sixty male rats were divided into; group I (control group), group II (T2DM group) induced by administration of high fat diet (HFD) and injection of streptozotocin (STZ) in low dose, group III (T2DM treated with MSCs), group IV (T2DM treated with obestatin), group V (T2DM treated with MSCs and obestatin). Fasting blood glucose, C-peptide, insulin and lipid profile were measured. HOMA IR and HOMA-beta were calculated. Pancreatic expression of insulin, glucagon like peptide -1 (GLP-1) and pancreatic duodenal homeobox 1 (Pdx1) mRNA levels were measured. In addition pancreatic histological changes, insulin and Bax were analyzed by immunohistochemical examination of islets of Langerhans. Diabetic rats showed significant increase in HOMA-IR, serum glucose and lipid profile levels with significant decrease in insulin, HOMA-beta, GLP-1 and Pdx1 levels. MSCs and obestatin caused significant improvement in all parameters with more significant improvement in combined therapy. The protective effects afforded by MSCs and obestatin may derive from improvement of the metabolic profile, antiapoptosis and by increase in pancreatic GLP-1and Pdx1 gene expression. PMID- 29186653 TI - Mesenchymal Stem Cell Differentiation into Adipocytes Is Equally Induced by Insulin and Proinsulin In Vitro. AB - Background and Objectives: In advanced beta-cell dysfunction, proinsulin is increasingly replacing insulin as major component of the secretion product. It has been speculated that proinsulin has at least the same adipogenic potency than insulin, leading to an increased tendency of lipid tissue formation in patients with late stage beta-cell dysfunction. Methods and Results: Mesenchymal stem cells obtained from liposuction material were grown in differentiation media containing insulin (0.01 MUmol), proinsulin (0.01 MUmol) or insulin+proinsulin (each 0.005 MUmol). Cell culture supernatants were taken from these experiments and an untreated control at weeks 1, 2, and 3, and were stored at -80 degrees C until analysis. Cell differentiation was microscopically supervised and adiponectin concentrations were measured as marker for differentiation into mature lipid cells. This experiment was repeated three times. No growth of lipid cells and no change in adiponectin values was observed in the negative control group (after 7/14/12 days: 3.2+/-0.5/3.3+/-0.1/4.4+/-0.5 ng/ml/12 h). A continuous differentiation into mature adipocytes (also confirmed by Red-Oil staining) and a corresponding increase in adiponectin values was observed in the experiments with insulin (3.6+/-1.9/5.1+/-1.4/13.3+/-1.5 ng/ml/12 h; p<0.05 week 1 vs. week 3) and proinsulin (3.3+/-1.2/3.5+/-0.3/12.2+/-1.2 ng/ml/12 h; p<0.05). Comparable effects were seen with the insulin/proinsulin combination. Conclusions: Proinsulin has the same adipogenic potential than insulin in vitro. Proinsulin has only 10~20% of the glucose-lowering effect of insulin. It can be speculated that the adipogenic potential of proinsulin may be a large contributor to the increased body weight problems in patients with type 2 diabetes and advanced beta-cell dysfunction. PMID- 29186654 TI - Treatment with Allogenic Mesenchymal Stromal Cells in a Murine Model of Systemic Lupus Erythematosus. AB - Objective: Pre-clinical and uncontrolled studies in patients with systemic lupus erythematosus (SLE) showed that mesenchymal stromal cells (MSCs) have a potential therapeutic role in refractory cases. The optimal therapeutic strategy in these patients remain to be elucidated. Our aim was to test the hypothesis that repeated administrations of 1*106/kg body weight of allogenic MSCs, that is a significantly lower dosage with respect to the fixed 1*106 MSC used in animal models, can be effective in improving the clinical course of a murine SLE model. Methods: Bone marrow derived MSCs were obtained from 12-week-old C57BL/6J mice. Seventy-five 8 weeks old female NZ mice were randomly assigned to receive via caudal vein the following alternative treatments: 1) single infusion of 106 MSCs/kg body weight at 18 weeks of age (NZs18) or at at 22 weeks of age (NZs22); 2) multiple monthly infusions of 106 MSCs/kg body weight starting at 18 weeks of age (NZM18) or at 22 weeks of age (NZM22); 3) saline infusions (NZc) Fifteen 8 weeks old C57BL/6J mice (Envigo, Huntingdon, UK) were used as untreated controls (C). Weekly, body weight was recorded and twenty-four hour urines were collected by metabolic cages for each animal; proteinuria was detected by dipstick analysis. At sacrifice, peripheral blood samples were collected from mice and anti-dsDNA antibodies were detected by enzyme immunoassorbent assay (ELISA) method using commercial kits. At sacrifice, kidneys were analyzed for histopathology and immunohistochemical analysis for B220, CD4, MPO, CD4+Foxp3, F40/80 infiltration was performed. Results: Proteinuria occurrence was delayed NZS and NZM mice, no differences were observed in anti-dsDNA autoantibody titer among the groups at the different time-points; at 36 weeks, no significant differences were observed in term of nephritis scores. Inflammatory cells deposition (MPO and F4/80 positive cells) in NZM was significantly higher than in NZ and NZS. An overexpression of B lymphocytes (B220) was found in NZM while T regulatory cells (CD4+ Foxp3+ cells) were reduced in both NZS and NZM with respect to NZc. Conclusions: Overall, our study failed to show a positive effect of a treatment with murine MSCs in this model and, for some aspects, even deleterious results seem to be observed. PMID- 29186655 TI - Engineering Bifunctional Antibodies with Constant Region Fusion Architectures. AB - We report a method to generate bifunctional antibodies by grafting full-length proteins into constant region loops of a full-length antibody or an antigen binding fragment (Fab). The fusion proteins retain the antigen binding activity of the parent antibody but have an additional activity associated with the protein insert. The engineered antibodies have excellent in vitro activity, physiochemical properties, and stability. Among these, a Her2 * CD3 bispecific antibody (BsAb) was constructed by inserting an anti-Her2 single-chain variable fragment (ScFv) into an anti-CD3 Fab. This bispecific antibody efficiently induces targeted cell lysis in the presence of effector cells at as low as sub picomolar concentrations in vitro. Moreover, the Her2 * CD3 BsAb shows potent in vivo antitumor activity in mouse Her22+ and Her21+ xenograft models. These results demonstrate that insertion of a full-length protein into non-CDR loops of antibodies provides a feasible approach to generate multifunctional antibodies for therapeutic applications.

AB - Aromatic chemical carcinogens can undergo enzymatic transformations to produce a range of electrophilic species that attach covalently to the C8-site of 2' deoxyguanosine (dG) to afford C8-dG adducts. The most studied C8-dG adducts are formed from arylamines and contain a N-linkage separating the dG from the C8-aryl moiety. Other carcinogenic species result in direct aryl ring attachment to the dG moiety, resulting in C-linked adducts. The resulting C-linked adducts have reduced conformational flexibility compared to the corresponding N-linked C8-dG adducts, which can alter their orientation in the DNA duplex. Described herein are structural studies of a fluorescent C-linked 4-fluorobiphenyl-dG (FBP-dG) that has been incorporated into the reiterated G3-postion of the 12-mer NarI sequence and those containing other 5'-flanking nucleobases. FBP-dG displays a strong preference for adopting a syn conformation in the fully paired NarI duplex to produce an intercalated structure that exhibits stacking interactions between the C-linked biphenyl and the flanking bases. FBP-dG is also shown to significantly stabilize the slippage mutagenic intermediate (SMI) duplex containing the lesion and 5'-flanking base within a 2-base bulge. FBP-dG exhibits fluorescence sensitivity to SMI duplex formation that can readily distinguish it from the fully paired duplex. Molecular dynamics simulations and optical spectroscopy for the NarI oligonucleotides containing the C-linked FBP-dG predict increased rigidity of the biphenyl in the syn conformation. The greater propensity to generate the promutagenic syn conformation for the C-linked FBP-dG adduct compared to the N-linked 4-aminobiphenyl-dG adduct (ABP-dG) suggests greater mutagenicity for the C-linked analogue. These results highlight the effect of the adduct linkage type on the conformational properties of adducted DNA. The turn-on emission response of FBP-dG in the SMI duplex may be a powerful tool for monitoring SMI formation in the NarI sequence upon synthesis with DNA polymerases.

AB - We present a new implementation of the template localization for the fully automated and parallizable incremental method, which excludes failures of this important step within the domain-specific basis set approach and thus ensures a higher reliability of the scheme, preserving its very high accuracy. Furthermore, we combine our method with an efficient focal-point ansatz to reach the complete basis set limit and carefully assess this approach for the first time with regard to reaction energies. For a test set of 51 reactions the incremental focal-point method with a basis set of moderate size provides a very high accuracy with respect to the complete basis set limit. That way, we are finally able to apply the scheme as a benchmark method (e.g., for density functionals) in the context of a relevant chemical topic, the intramolecular decomposition of tris-perfluoro tert-butoxyalane (43 heavy atoms, 352 electrons). PMID- 29186658 TI - Stereoselectivity of Proline/Cyclobutane Amino Acid-Containing Peptide Organocatalysts for Asymmetric Aldol Additions: A Rationale. AB - Several alpha,beta,alpha- or alpha,gamma,alpha-tripeptides, consisting of a central cyclobutane beta- or gamma-amino acid being flanked by two d- or l proline residues, have been synthesized and tested as organocatalysts in asymmetric aldol additions. High yields and enantioselectivities have been achieved with alpha,gamma,alpha-tripeptides, being superior to peptides containing a cyclobutane beta-amino acid residue. This is probably due to their high rigidity, which hinders some of the peptide catalysts to adopt the proper active conformation. This reasoning correlates with the major conformation of the peptides in the ground state, as suggested by 1H NMR and computational calculations. The configuration of the aldol products is controlled by the proline chirality, and consequently, the R/S configuration of aldol products can be tuned by the use of either commercially available d- or l-proline. The enantioselectivity in the aldol reactions is reversed if the reactions are carried out in the presence of water or other protic solvents such as methanol. Spectroscopic and theoretical investigations revealed that this effect is not the consequence of conformational changes in the catalyst but rather caused by the participation of a water molecule in the rate determining transition state, in such a way that the preferential nucleophilic attack is oriented to the opposite enantiotopic aldehyde face. PMID- 29186659 TI - Operating Mechanisms of Mesoscopic Perovskite Solar Cells through Impedance Spectroscopy and J-V Modeling. AB - The performance of perovskite solar cell (PSC) is highly sensitive to deposition conditions, the substrate, humidity, and the efficiency of solvent extraction. However, the physical mechanism involved in the observed changes of efficiency with different deposition conditions has not been elucidated yet. In this work, PSCs were fabricated by the antisolvent deposition (AD) and recently proposed air extraction antisolvent (AAD) process. Impedance analysis and J-V curve fitting were used to analyze the photogeneration, charge transportation, recombination, and leakage properties of PSCs. It can be elucidated that the improvement in morphology of perovskite film promoted by AAD method leads to increase in light absorption, reduction in recombination sites, and interstitial defects, thus enhancing the short-circuit current density, open-circuit voltage, and fill factor. This study will open up doors for further improvement of device and help in understanding its physical mechanism and its relation to the deposition methods. PMID- 29186660 TI - Nanoparticle Stability in Axial InAs-InP Nanowire Heterostructures with Atomically Sharp Interfaces. AB - The possibility to expand the range of material combinations in defect-free heterostructures is one of the main motivations for the great interest in semiconductor nanowires. However, most axial nanowire heterostructures suffer from interface compositional gradients and kink formation, as a consequence of nanoparticle-nanowire interactions during the metal-assisted growth. Understanding such interactions and how they affect the growth mode is fundamental to achieve a full control over the morphology and the properties of nanowire heterostructures for device applications. Here we demonstrate that the sole parameter affecting the growth mode (straight or kinked) of InP segments on InAs nanowire stems by the Au-assisted method is the nanoparticle composition. Indeed, straight InAs-InP nanowire heterostructures are obtained only when the In/Au ratio in the nanoparticles is low, typically smaller than 1.5. For higher In content, the InP segments tend to kink. Tailoring the In/Au ratio by the precursor fluxes at a fixed growth temperature enables us to obtain straight and radius-uniform InAs-InP nanowire heterostructures (single and double) with atomically sharp interfaces. We present a model that is capable of describing all the experimentally observed phenomena: straight growth versus kinking, the stationary nanoparticle compositions in pure InAs and InAs-InP nanowires, the crystal phase trends, and the interfacial abruptness. By taking into account different nanowire/nanoparticle interfacial configurations (forming wetting or nonwetting monolayers in vertical or tapered geometry), our generalized model provides the conditions of nanoparticle stability and abrupt heterointerfaces for a rich variety of growth scenarios. Therefore, our results provide a powerful tool for obtaining high quality InAs-InP nanowire heterostructures with well controlled properties and can be extended to other material combinations based on the group V interchange.

AB - In this study, different boronate caps were used to optimize biodistribution properties of radiotracers [99mTcCl(CDO)(CDOH)2B-R] (1, R = 3S; 2, R = 3SP; 3, R = 3MS; 4, R = 3DMS; 5, R = 3MSB; 6, R = 3MMS; 7, R = 3MSA; 8, R = 3DMSA; 9, R = 4S; 10, R = 4MS; 11, R = 4MSB). Among the 11 new 99mTc radiotracers, 2 shows the most promising characteristics of an optimal heart imaging agent. Its initial heart uptake is close to that of 99mTc-Teboroxime, but its heart retention time is significantly longer. Its heart/liver, heart/lung, and heart/muscle ratios are also better than those of 99mTc-Teboroxime. The SPECT image quality with 2 in SD rats is better than that with 99mTc-Teboroxime. The high initial heart uptake, long heart retention, and high heart/background ratios make 2 an excellent SPECT radiotracer for MPI. PMID- 29186663 TI - The Plausibility of "Bronchiolotrauma". PMID- 29186662 TI - Ultrasmall-in-Nano Approach: Enabling the Translation of Metal Nanomaterials to Clinics. AB - Currently, nanomaterials are of widespread use in daily commercial products. However, the most-promising and potentially impacting application is in the medical field. In particular, nanosized noble metals hold the promise of shifting the current medical paradigms for the detection and therapy of neoplasms thanks to the: (i) localized surface plasmon resonances (LSPRs), (ii) high electron density, and (iii) suitability for straightforward development of all-in-one nanoplatforms. Nonetheless, there is still no clinically approved noble metal nanomaterial for cancer therapy and diagnostics. The clinical translation of noble metal nanoparticles (NPs) is mainly prevented by the issue of persistence in organism after the medical action. Such persistence increases the likelihood of toxicity and the interference with common medical diagnoses. Size reduction to ultrasmall nanoparticles (USNPs) is a suitable approach to promoting metal excretion by the renal pathway. However, most of the functionalities of NPs are lost or severely altered in USNPs, jeopardizing clinical applications. A ground breaking advance to jointly combine the appealing behaviors of NPs with metal excretion relies on the ultrasmall-in-nano approach for the design of all-in-one degradable nanoplatforms composed of USNPs. Such nanoarchitectures might lead to the delivery of a novel paradigm for nanotechnology, enabling the translation of noble metal nanomaterials to clinics to treat carcinomas in a less-invasive and more-efficient manner. This Review covers the recent progresses related to this exciting approach. The most-significant nanoarchitectures designed with the ultrasmall-in-nano approach are discussed, and perspectives on these nanoarchitectures are provided.

PMID- 29186666 TI - The Moderating Effect of Urban Versus Rural Residence on the Relationship Between Type of Birth Attendant and Early Initiation of Breastfeeding in Ghana. AB - BACKGROUND: Early initiation of breastfeeding increases the likelihood of longer duration of breastfeeding. Factors associated with breastfeeding include maternal sociodemographic, behavioral and health-related characteristics, infant health characteristics, and perinatal factors. Research aim: This study aimed to determine the association between type of birth attendant and early initiation of breastfeeding among women in Ghana. METHODS: A cross-sectional study was conducted using women ( N = 3,087) who participated in the 2014 Ghana Demographic and Health Survey. The main outcome of interest was early initiation of breastfeeding, defined as provision of mother's milk to the infant within 1 hr of birth. Chi-square tests and multivariable logistic regression modeling were performed. RESULTS: Breastfeeding was initiated within 1 hr of birth by 58.3% of women. In the multivariable model, there was a significant interaction between type of birth attendant and place of residence on early initiation of breastfeeding. For rural areas, compared with women who had a nurse or midwife as their birth attendant, the multivariable odds ratios [95% confidence intervals] for early initiation of breastfeeding were lower among women whose birth attendant was a relative or other, 0.20 [0.07, 0.55], p = .002; village health volunteer or traditional health practitioner, 0.21 [0.07, 0.62], p = .005; none, 0.34 [0.12, 0.93], p = .035; community health officer, 0.42 [0.21, 0.85], p = .016; and doctor, 0.48 [0.24, 0.96], p = .037. For urban areas, no significant association was detected between type of birth attendant and early initiation of breastfeeding. CONCLUSION: Findings from the study highlight the need for focused, context-specific, early initiation of breastfeeding promotion and intervention, especially for women and their birth attendants in rural areas. PMID- 29186665 TI - Discovery and Characterization of Chemical Compounds That Inhibit the Function of Aspartyl-tRNA Synthetase from Pseudomonas aeruginosa. AB - Pseudomonas aeruginosa, an opportunistic pathogen, is highly susceptible to developing resistance to multiple antibiotics. The gene encoding aspartyl-tRNA synthetase (AspRS) from P. aeruginosa was cloned and the resulting protein characterized. AspRS was kinetically evaluated, and the KM values for aspartic acid, ATP, and tRNA were 170, 495, and 0.5 MUM, respectively. AspRS was developed into a screening platform using scintillation proximity assay (SPA) technology and used to screen 1690 chemical compounds, resulting in the identification of two inhibitory compounds, BT02A02 and BT02C05. The minimum inhibitory concentrations (MICs) were determined against nine clinically relevant bacterial strains, including efflux pump mutant and hypersensitive strains of P. aeruginosa. The compounds displayed broad-spectrum antibacterial activity and inhibited growth of the efflux and hypersensitive strains with MICs of 16 MUg/mL. Growth of wild-type strains were unaffected, indicating that efflux was likely responsible for this lack of activity. BT02A02 did not inhibit growth of human cell cultures at any concentration. However, BT02C05 did inhibit human cell cultures with a cytotoxicity concentration (CC50) of 61.6 MUg/mL. The compounds did not compete with either aspartic acid or ATP for binding AspRS, indicating that the mechanism of action of the compound occurs outside the active site of aminoacylation. PMID- 29186668 TI - Emulation of Colonic Oxygen Gradients in a Microdevice. AB - Gut-on-a-chip in vitro modeling is an emerging field, as the human gut epithelium and gut microbiome have been recently identified as novel drug targets for a wide variety of diseases. Realistic in vitro gut models require a variety of precise environmental cues, such as chemical and gas gradients, in combination with substrates like mucus that support the growth of microbial communities. This technical brief describes a microfluidic architecture capable of developing a physiologically relevant oxygen gradient that emulates the oxygen profile proximal to the epithelial inner lining of the human colon. The device generates stable and repeatable defined oxygen gradients from 0% to 4 % partial pressure O2 over a length scale of hundreds of microns, and was applied to study the effects of oxygenation on the structure of native mucus that lines the colon wall. Using simulation as a design tool for hybrid gas-liquid microfluidic devices enables on chip creation of defined, physiologically oxygen gradients. These microfluidic architectures have powerful potential applications for gut physiology, including providing optimal oxygenation conditions for the culture of mammalian epithelial cells in the gut lining, as well as creating a realistic mimic of the oxygen gradient found in the intestinal lumen for complex microbiome cultures. PMID- 29186669 TI - High-Capacity Redox Polymer Electrodes: Applications in Molecular and Cellular Processing. AB - We present methods to fabricate high-capacity redox electrodes using thick membrane or fiber casting of conjugated polymer solutions. Unlike common solution casting or printing methods used in current organic electronics, the presented techniques enable production of PEDOT:PSS electrodes with high charge capacity and the capability to operate under applied voltages greater than 100 V without electrochemical overoxidation. The electrodes are shown integrated into several electrokinetic components commonly used in automated bioprocess or bioassay workflows, including electrophoretic DNA separation and extraction, cellular electroporation/lysis, and electroosmotic pumping. Unlike current metal electrodes used in these applications, the high-capacity polymer electrodes are shown to function without electrolysis of solvent (i.e., without production of excess H+, OH-, and H2O2 by-products). In addition, each component fabricated using the electrodes is shown to have superior capabilities compared with those fabricated with common metal electrodes. These innovations in electrokinetics include a low-voltage/high-pressure electroosmotic pump, and a "flow battery" (in which electrochemical discharge is used to generate electroosmotic flow in the absence of an applied potential). The novel electrodes (and electrokinetic demonstrations) enable new applications of organic electronics within the biology, health care, and pharmaceutical fields.

AB - : Extreme weather and climate-related events affect human health by causing death, injury, and illness, as well as having large socioeconomic impacts. Climate change has caused changes in extreme event frequency, intensity, and geographic distribution, and will continue to be a driver for change in the future. Some of these events include heat waves, droughts, wildfires, dust storms, flooding rains, coastal flooding, storm surges, and hurricanes. The pathways connecting extreme events to health outcomes and economic losses can be diverse and complex. The difficulty in predicting these relationships comes from the local societal and environmental factors that affect disease burden. More information is needed about the impacts of climate change on public health and economies to effectively plan for and adapt to climate change. This paper describes some of the ways extreme events are changing and provides examples of the potential impacts on human health and infrastructure. It also identifies key research gaps to be addressed to improve the resilience of public health to extreme events in the future.

PMID- 29186673 TI - Disparate Postsynaptic Induction Mechanisms Ultimately Converge to Drive the Retrograde Enhancement of Presynaptic Efficacy. AB - Retrograde signaling systems are fundamental modes of communication synapses utilize to dynamically and adaptively modulate activity. However, the inductive mechanisms that gate retrograde communication in the postsynaptic compartment remain enigmatic. We have investigated retrograde signaling at the Drosophila neuromuscular junction, where three seemingly disparate perturbations to the postsynaptic cell trigger a similar enhancement in presynaptic neurotransmitter release. We show that the same presynaptic genetic machinery and enhancements in active zone structure are utilized by each inductive pathway. However, all three induction mechanisms differ in temporal, translational, and CamKII activity requirements to initiate retrograde signaling in the postsynaptic cell. Intriguingly, pharmacological blockade of postsynaptic glutamate receptors, and not calcium influx through these receptors, is necessary and sufficient to induce rapid retrograde homeostatic signaling through CamKII. Thus, three distinct induction mechanisms converge on the same retrograde signaling system to drive the homeostatic strengthening of presynaptic neurotransmitter release. PMID- 29186674 TI - Cellular and Molecular Anatomy of the Human Neuromuscular Junction. AB - The neuromuscular junction (NMJ) plays a fundamental role in transferring information from lower motor neuron to skeletal muscle to generate movement. It is also an experimentally accessible model synapse routinely studied in animal models to explore fundamental aspects of synaptic form and function. Here, we combined morphological techniques, super-resolution imaging, and proteomic profiling to reveal the detailed cellular and molecular architecture of the human NMJ. Human NMJs were significantly smaller, less complex, and more fragmented than mouse NMJs. In contrast to mice, human NMJs were also remarkably stable across the entire adult lifespan, showing no signs of age-related degeneration or remodeling. Super-resolution imaging and proteomic profiling revealed distinctive distribution of active zone proteins and differential expression of core synaptic proteins and molecular pathways at the human NMJ. Taken together, these findings reveal human-specific cellular and molecular features of the NMJ that distinguish them from comparable synapses in other mammalian species. PMID- 29186675 TI - Inactivation of Mechanically Activated Piezo1 Ion Channels Is Determined by the C Terminal Extracellular Domain and the Inner Pore Helix. AB - Piezo proteins form mechanically activated ion channels that are responsible for our sense of light touch, proprioception, and vascular blood flow. Upon activation by mechanical stimuli, Piezo channels rapidly inactivate in a voltage dependent manner through an unknown mechanism. Inactivation of Piezo channels is physiologically important, as it modulates overall mechanical sensitivity, gives rise to frequency filtering of repetitive mechanical stimuli, and is itself the target of numerous human disease-related channelopathies that are not well understood mechanistically. Here, we identify the globular C-terminal extracellular domain as a structure that is sufficient to confer the time course of inactivation and a single positively charged lysine residue at the adjacent inner pore helix as being required for its voltage dependence. Our results are consistent with a mechanism for inactivation that is mediated through voltage dependent conformations of the inner pore helix and allosteric coupling with the C-terminal extracellular domain. PMID- 29186677 TI - The Methyltransferase Setd8 Is Essential for Erythroblast Survival and Maturation. AB - Erythropoiesis is a highly regulated process that generates enucleate red blood cells from committed erythroid progenitors. Chromatin condensation culminating in enucleation is a defining feature of this process. Setd8 is the sole enzyme that can mono-methylate histone H4, lysine 20 and is highly expressed in erythroblasts compared to most other cell types. Erythroid Setd8 deletion results in embryonic lethality from severe anemia due to impaired erythroblast survival and proliferation. Setd8 protein levels are also uniquely regulated in erythroblasts, suggesting a cell-type-specific role for Setd8 during terminal maturation. Consistent with this hypothesis, Setd8 Delta/Delta erythroblasts have profound defects in transcriptional repression, chromatin condensation, and heterochromatin accumulation. Together, these results suggest that Setd8, used by most cells to promote mitotic chromatin condensation, is an essential aspect of the transcriptional repression and chromatin condensation that are hallmarks of terminal erythroid maturation. PMID- 29186676 TI - The Circadian Clock Regulates Adipogenesis by a Per3 Crosstalk Pathway to Klf15. AB - The generation of new adipocytes from precursor cells (adipogenesis) has implications for systemic metabolism and is a commonly used model for studying the process of cell differentiation in vitro. Previous studies from us and others suggested that the peripheral circadian clock can influence adipogenesis in vitro, but the mechanisms driving this activity and the relevance for adipogenesis in vivo are unknown. Here we reveal that mouse adipocyte precursor cells (APCs) contain a circadian clock that oscillates in vivo. We expose context specific features of the clock in APCs: expression of the canonical core clock component Per1 does not significantly oscillate, whereas the lesser-understood paralog Per3 has a prominent rhythm. We discovered that deletion of Per3 promotes adipogenesis in vivo by a clock output pathway in which PER3 and BMAL1 directly regulate Klf15 expression. These findings demonstrate that Per3 has a major role in the APC clock and regulates adipogenesis in vivo. PMID- 29186678 TI - Hyperglycemia Impairs Neutrophil Mobilization Leading to Enhanced Metastatic Seeding. AB - Preexisting diabetes is a risk factor for the development of multiple types of cancer. Additionally, diabetic patients face a poorer prognosis when diagnosed with cancer. To gain insight into the effects of hyperglycemia, a hallmark of diabetes, on tumor growth and metastatic progression, we combined mouse models of cancer and hyperglycemia. We show that while hyperglycemia attenuates primary tumor growth, it concomitantly increases metastatic seeding in a distant organ. We further show that the increase in metastatic seeding is due to impaired secretion of granulocyte colony-stimulating factor (G-CSF) and impaired neutrophil mobilization. Normalizing blood glucose levels using insulin rescues neutrophil recruitment and tumor growth and concomitantly reduces metastatic seeding. These results provide links among hyperglycemia-induced changes in neutrophil mobilization, primary tumor growth, and metastatic progression. Furthermore, our observations highlight the importance of normalizing blood glucose levels in hyperglycemic cancer patients. PMID- 29186679 TI - Functional Specialization of the Primate Frontal Lobe during Cognitive Control of Vocalizations. AB - Cognitive vocal control is indispensable for human language. Frontal lobe areas are involved in initiating purposeful vocalizations, but their functions remain elusive. We explored the respective roles of frontal lobe areas in initiating volitional vocalizations. Macaques were trained to vocalize in response to visual cues. Recordings from the ventrolateral prefrontal cortex (vlPFC), the anterior cingulate cortex (ACC), and the pre-supplementary motor area (preSMA) revealed single-neuron and population activity differences. Pre-vocal activity appeared first after the go cue in vlPFC, showing onset activity that was tightly linked to vocal reaction times. However, pre-vocal ACC onset activity was not indicative of call timing; instead, ramping activity reaching threshold values betrayed call onset. Neurons in preSMA showed weakest correlation with volitional call initiation and timing. These results suggest that vlPFC encodes the decision to produce volitional calls, whereas downstream ACC represents a motivational preparatory signal, followed by a general motor priming signal in preSMA. PMID- 29186680 TI - Astrocytic l-Lactate Signaling Facilitates Amygdala-Anterior Cingulate Cortex Synchrony and Decision Making in Rats. AB - Human brain imaging studies have revealed the anterior cingulate cortex (ACC) as a key brain region for mediating visceral-pain-cognitive interactions. Recently, we characterized impairments of long-term potentiation and spike-field coherence in the basolateral amygdala (BLA)-ACC network in association with a decision making deficit in rats with visceral hypersensitivity (VH). Now, by combining integrative neurobiological approaches, we show that ACC-reactive astrogliosis and activity-dependent impairment of lactate release occur in VH rats. Exogenous lactate supply rescues chronic-visceral-pain-caused impairments of ACC phase locking and decision making, which can be mimicked by optogenetic activation of ACC astrocytes. Large-scale electrophysiological recordings in free-moving animals during a decision-making task indicate that optogenetic astrocytic activation improves decision-making performance and engages ACC phase locking and BLA-to-ACC information flow. Collectively, these observations support the idea of an "astrocyte-neuron l-lactate shuttle" and suggest that targeting astrocytes may help with cognitive dysfunctions under chronic visceral pain. PMID- 29186682 TI - Control of Gene Expression in Senescence through Transcriptional Read-Through of Convergent Protein-Coding Genes. AB - Antisense RNAs are non-coding RNAs that can regulate their corresponding sense RNAs and are generally produced from specific promoters. We uncover here a family of antisense RNAs, named START RNAs, produced during cellular senescence by transcriptional read-through at convergent protein-coding genes. Importantly, START RNAs repress the expression of their corresponding sense RNAs. In proliferative cells, we found that the Pol II elongation rate is limited downstream of TTS at START loci, allowing transcription termination to occur before Pol II reaches the convergent genes, thus preventing antisense RNA production and interference with the expression of the convergent genes. START RNAs are repressed by H2A.Z histone variant, whose local occupancy decreases in senescence. Our results thus uncover a mechanism of gene expression regulation relying on read-through antisense transcript production at convergent genes, underlining the functional importance of chromatin regulation in the control of RNA pol II elongation rate at intergenic regions. PMID- 29186681 TI - Gamma Oscillations in Rat Hippocampal Subregions Dentate Gyrus, CA3, CA1, and Subiculum Underlie Associative Memory Encoding. AB - Neuronal oscillations in the rat hippocampus relate to both memory and locomotion, raising the question of how these cognitive and behavioral correlates interact to determine the oscillatory network state of this region. Here, rats freely locomoted while performing an object-location task designed to test hippocampus-dependent spatial associative memory. Rhythmic activity in theta, beta, slow gamma, and fast gamma frequency ranges were observed in both action potentials and local field potentials (LFPs) across four main hippocampal subregions. Several patterns of LFP oscillations corresponded to overt behavior (e.g., increased dentate gyrus-CA3 beta coherence during stationary moments and CA1-subiculum theta coherence during locomotion). In comparison, slow gamma (~40 Hz) oscillations throughout the hippocampus related most specifically to object location associative memory encoding rather than overt behavior. The results help to untangle how hippocampal oscillations relate to both memory and motion and single out slow gamma oscillations as a distinguishing correlate of spatial associative memory. PMID- 29186683 TI - TRIM48 Promotes ASK1 Activation and Cell Death through Ubiquitination-Dependent Degradation of the ASK1-Negative Regulator PRMT1. AB - Apoptosis signal-regulating kinase 1 (ASK1) is an oxidative stress-responsive kinase that is regulated by various interacting molecules and post-translational modifications. However, how these molecules and modifications cooperatively regulate ASK1 activity remains largely unknown. Here, we showed that tripartite motif 48 (TRIM48) orchestrates the regulation of oxidative stress-induced ASK1 activation. A pull-down screen identified a TRIM48-interacting partner, protein arginine methyltransferase 1 (PRMT1), which negatively regulates ASK1 activation by enhancing its interaction with thioredoxin (Trx), another ASK1-negative regulator. TRIM48 facilitates ASK1 activation by promoting K48-linked polyubiquitination and degradation of PRMT1. TRIM48 knockdown suppressed oxidative stress-induced ASK1 activation and cell death, whereas forced expression promoted cancer cell death in mouse xenograft model. These results indicate that TRIM48 facilitates oxidative stress-induced ASK1 activation and cell death through ubiquitination-dependent degradation of PRMT1. This study provides a cell death mechanism fine-tuned by the crosstalk between enzymes that engage various types of post-translational modifications. PMID- 29186685 TI - Noncanonical Pathway for Regulation of CCL2 Expression by an mTORC1-FOXK1 Axis Promotes Recruitment of Tumor-Associated Macrophages. AB - C-C chemokine ligand 2 (CCL2) plays pivotal roles in tumor formation, progression, and metastasis. Although CCL2 expression has been found to be dependent on the nuclear factor (NF)-kappaB signaling pathway, the regulation of CCL2 production in tumor cells has remained unclear. We have identified a noncanonical pathway for regulation of CCL2 production that is mediated by mammalian target of rapamycin complex 1 (mTORC1) but independent of NF-kappaB. Multiple phosphoproteomics approaches identified the transcription factor forkhead box K1 (FOXK1) as a downstream target of mTORC1. Activation of mTORC1 induces dephosphorylation of FOXK1, resulting in transactivation of the CCL2 gene. Inhibition of the mTORC1-FOXK1 axis attenuated insulin-induced CCL2 production as well as the accumulation of tumor-associated monocytes-macrophages and tumor progression in mice. Our results suggest that FOXK1 directly links mTORC1 signaling and CCL2 expression in a manner independent of NF-kappaB and that CCL2 produced by this pathway contributes to tumor progression. PMID- 29186684 TI - Pancreatic Adenocarcinoma Therapeutic Targets Revealed by Tumor-Stroma Cross-Talk Analyses in Patient-Derived Xenografts. AB - Preclinical models based on patient-derived xenografts have remarkable specificity in distinguishing transformed human tumor cells from non-transformed murine stromal cells computationally. We obtained 29 pancreatic ductal adenocarcinoma (PDAC) xenografts from either resectable or non-resectable patients (surgery and endoscopic ultrasound-guided fine-needle aspirate, respectively). Extensive multiomic profiling revealed two subtypes with distinct clinical outcomes. These subtypes uncovered specific alterations in DNA methylation and transcription as well as in signaling pathways involved in tumor stromal cross-talk. The analysis of these pathways indicates therapeutic opportunities for targeting both compartments and their interactions. In particular, we show that inhibiting NPC1L1 with Ezetimibe, a clinically available drug, might be an efficient approach for treating pancreatic cancers. These findings uncover the complex and diverse interplay between PDAC tumors and the stroma and demonstrate the pivotal role of xenografts for drug discovery and relevance to PDAC. PMID- 29186686 TI - Testosterone Attenuates Group 2 Innate Lymphoid Cell-Mediated Airway Inflammation. AB - Sex hormones regulate many autoimmune and inflammatory diseases, including asthma. As adults, asthma prevalence is 2-fold greater in women compared to men. The number of group 2 innate lymphoid cells (ILC2) is increased in patients with asthma, and we investigate how testosterone attenuates ILC2 function. In patients with moderate to severe asthma, we determine that women have an increased number of circulating ILC2 compared to men. ILC2 from adult female mice have increased IL-2-mediated ILC2 proliferation versus ILC2 from adult male mice, as well as pre pubescent females and males. Further, 5alpha-dihydrotestosterone, a hormone downstream of testosterone, decreases lung ILC2 numbers and IL-5 and IL-13 expression from ILC2. In vivo, testosterone attenuated Alternaria-extract-induced IL-5+ and IL-13+ ILC2 numbers and lung eosinophils by intrinsically decreasing lung ILC2 numbers, as well as by decreasing expression of IL-33 and thymic stromal lymphopoietin (TSLP), ILC2-stimulating cytokines. Collectively, these findings provide a foundational understanding of sexual dimorphism in ILC2 function. PMID- 29186687 TI - Perivascular Fibroblasts of the Developing Spleen Act as LTalpha1beta2-Dependent Precursors of Both T and B Zone Organizer Cells. AB - T and B cell compartmentalization is a hallmark of secondary lymphoid organs and is maintained by chemokine-expressing stromal cells. How this stromal cell network initially develops and differentiates into two distinct subsets is poorly known, especially for the splenic white pulp (WP). Here, we show that perivascular fibroblast precursors are triggered by LTalpha1beta2 signals to expand, express CCL19/21, and then differentiate into two functionally distinct fibroblast subsets responsible for B and T cell clustering and WP compartmentalization. Failure to express or sense CCL19 leads to impaired T zone development, while lack of B cells or LTalpha1beta2 leads to an earlier and stronger impairment in WP development. We therefore propose that WP development proceeds in multiple steps, with LTalpha1beta2+ B cells acting as major inducer cells driving the expansion and gradual differentiation of perivascular fibroblasts into T and B zone organizer cells. PMID- 29186689 TI - Lymphocytes Negatively Regulate NK Cell Activity via Qa-1b following Viral Infection. AB - NK cells can reduce anti-viral T cell immunity during chronic viral infections, including infection with the lymphocytic choriomeningitis virus (LCMV). However, regulating factors that maintain the equilibrium between productive T cell and NK cell immunity are poorly understood. Here, we show that a large viral load resulted in inhibition of NK cell activation, which correlated with increased expression of Qa-1b, a ligand for inhibitory NK cell receptors. Qa-1b was predominantly upregulated on B cells following LCMV infection, and this upregulation was dependent on type I interferons. Absence of Qa-1b resulted in increased NK cell-mediated regulation of anti-viral T cells following viral infection. Consequently, anti-viral T cell immunity was reduced in Qa-1b- and NKG2A-deficient mice, resulting in increased viral replication and immunopathology. NK cell depletion restored anti-viral immunity and virus control in the absence of Qa-1b. Taken together, our findings indicate that lymphocytes limit NK cell activity during viral infection in order to promote anti-viral T cell immunity. PMID- 29186688 TI - Receptor Activator of NF-kappaB Orchestrates Activation of Antiviral Memory CD8 T Cells in the Spleen Marginal Zone. AB - The spleen plays an important role in protective immunity to bloodborne pathogens. Macrophages and dendritic cells (DCs) in the spleen marginal zone capture microbial antigens to trigger adaptive immune responses. Marginal zone macrophages (MZMs) can also act as a replicative niche for intracellular pathogens, providing a platform for mounting the immune response. Here, we describe a role for RANK in the coordinated function of antigen-presenting cells in the spleen marginal zone and triggering anti-viral immunity. Targeted deletion of RANK results in the selective loss of CD169+ MZMs, which provide a niche for viral replication, while RANK signaling in DCs promotes the recruitment and activation of anti-viral memory CD8 T cells. These studies reveal a role for the RANKL/RANK signaling axis in the orchestration of protective immune responses in the spleen marginal zone that has important implications for the host response to viral infection and induction of acquired immunity. PMID- 29186690 TI - Growth of B Cell Receptor Microclusters Is Regulated by PIP2 and PIP3 Equilibrium and Dock2 Recruitment and Activation. AB - The growth of B cell receptor (BCR) microclusters upon antigen stimulation drives B cell activation. Here, we show that PI3K-mediated PIP3 production is required for the growth of BCR microclusters. This growth is likely inhibited by PTEN and dependent on its plasma membrane binding and lipid phosphatase activities. Mechanistically, we find that PIP3-dependent recruitment and activation of a guanine nucleotide exchange factor, Dock2, is required for the sustained growth of BCR microclusters through remodeling of the F-actin cytoskeleton. As a consequence, Dock2 deficiency significantly disrupts the structure of the B cell immunological synapse. Finally, we find that primary B cells from systemic lupus erythematosus (SLE) patients exhibit more prominent BCR and PI3K microclusters than B cells from healthy controls. These results demonstrate the importance of a PI3K- and PTEN-governed PIP2 and PIP3 equilibrium in regulating the activation of B cells through Dock2-controlled growth of BCR microclusters. PMID- 29186691 TI - Immunoproteasomes Control the Homeostasis of Medullary Thymic Epithelial Cells by Alleviating Proteotoxic Stress. AB - The sole nonredundant role of the thymic medulla is to induce central tolerance, a vital process that depends on promiscuous gene expression (pGE), a unique feature of medullary thymic epithelial cells (mTECs). Although pGE enhances transcription of >3,000 genes in mTECs, its impact on the regulation of protein homeostasis remains unexplored. Here, we report that, because of pGE, mature mTECs synthesize substantially more proteins than other cell types and are exquisitely sensitive to loss of immunoproteasomes (IPs). Indeed, IP deficiency causes proteotoxic stress in mTECs and leads to exhaustion of postnatal mTEC progenitors. Moreover, IP-deficient mice show accelerated thymic involution, which is characterized by a selective loss of mTECs and multiorgan autoimmune manifestations. We conclude that pGE, the quintessential feature of mTECs, is a major burden for the maintenance of proteostasis, which is alleviated by the constitutive expression of IPs in mTECs. PMID- 29186692 TI - Quiescence Exit of Tert+ Stem Cells by Wnt/beta-Catenin Is Indispensable for Intestinal Regeneration. AB - Fine control of stem cell maintenance and activation is crucial for tissue homeostasis and regeneration. However, the mechanism of quiescence exit of Tert+ intestinal stem cells (ISCs) remains unknown. Employing a Tert knockin (TertTCE/+) mouse model, we found that Tert+ cells are long-term label-retaining self-renewing cells, which are partially distinguished from the previously identified +4 ISCs. Tert+ cells become mitotic upon irradiation (IR) injury. Conditional ablation of Tert+ cells impairs IR-induced intestinal regeneration but not intestinal homeostasis. Upon IR injury, Wnt signaling is specifically activated in Tert+ cells via the ROS-HIFs-transactivated Wnt2b signaling axis. Importantly, conditional knockout of beta-catenin/Ctnnb1 in Tert+ cells undermines IR-induced quiescence exit of Tert+ cells, which subsequently impedes intestinal regeneration. Our results that Wnt-signaling-induced activation of Tert+ ISCs is indispensable for intestinal regeneration unveil the underlying mechanism for how Tert+ stem cells undergo quiescence exit upon tissue injury. PMID- 29186693 TI - Osteocyte-Intrinsic TGF-beta Signaling Regulates Bone Quality through Perilacunar/Canalicular Remodeling. AB - Poor bone quality contributes to bone fragility in diabetes, aging, and osteogenesis imperfecta. However, the mechanisms controlling bone quality are not well understood, contributing to the current lack of strategies to diagnose or treat bone quality deficits. Transforming growth factor beta (TGF-beta) signaling is a crucial mechanism known to regulate the material quality of bone, but its cellular target in this regulation is unknown. Studies showing that osteocytes directly remodel their perilacunar/canalicular matrix led us to hypothesize that TGF-beta controls bone quality through perilacunar/canalicular remodeling (PLR). Using inhibitors and mice with an osteocyte-intrinsic defect in TGF-beta signaling (TbetaRIIocy-/-), we show that TGF-beta regulates PLR in a cell intrinsic manner to control bone quality. Altogether, this study emphasizes that osteocytes are key in executing the biological control of bone quality through PLR, thereby highlighting the fundamental role of osteocyte-mediated PLR in bone homeostasis and fragility. PMID- 29186696 TI - A Highly Sensitive FRET Biosensor for AMPK Exhibits Heterogeneous AMPK Responses among Cells and Organs. AB - AMP-activated protein kinase (AMPK), a master regulator of cellular metabolism, is a potential target for type 2 diabetes. Although extensive in vitro studies have revealed the complex regulation of AMPK, much remains unknown about the regulation in vivo. We therefore developed transgenic mice expressing a highly sensitive fluorescence resonance energy transfer (FRET)-based biosensor for AMPK, called AMPKAR-EV. AMPKAR-EV allowed us to readily examine the role of LKB1, a canonical stimulator of AMPK, in drug-induced activation and inactivation of AMPK in vitro. In transgenic mice expressing AMPKAR-EV, the AMP analog AICAR activated AMPK in muscle. In contrast, the antidiabetic drug metformin activated AMPK in liver, highlighting the organ-specific action of AMPK stimulators. Moreover, we found that AMPK was activated primarily in fast-twitch muscle fibers after tetanic contraction and exercise. These observations suggest that the AMPKAR-EV mouse will pave a way to understanding the heterogeneous responses of AMPK among cell types in vivo. PMID- 29186697 TI - A High-Throughput Screen for Yeast Replicative Lifespan Identifies Lifespan Extending Compounds. AB - Progress in aging research is constrained by the time requirement of measuring lifespans. Even the most rapid model for eukaryotic aging, the replicative lifespan of Saccharomyces cerevisiae, is technically limited to only several lifespan measurements each day. Here we report a 384-well plate-based technique to measure replicative lifespan, termed High-Life. Using the High-Life technique, a single researcher can compare lifespan for more than 1,000 conditions per day. We validated the technique with long-lived mutant strains and the lifespan extending compound ibuprofen. We also applied this technique to screen a small compound library for lifespan extension. Two hits, terreic acid and mycophenolic acid, were validated on our single-cell replicator device and found to extend mean replicative lifespan by 15% and 20%, respectively. Together, we report a technique for high-throughput lifespan measurement, and we identify two lifespan extending compounds. Our technique could be used to efficiently drive early-stage discovery of pro-longevity therapeutics. PMID- 29186698 TI - Effect of atorvastatin on behavioral alterations and neuroinflammation during epileptogenesis. AB - Temporal lobe epilepsy (TLE) is the most frequent and medically refractory type of epilepsy in humans. In addition to seizures, patients with TLE suffer from behavioral alterations and cognitive deficits. Poststatus epilepticus model of TLE induced by pilocarpine in rodents has enhanced the understanding of the processes leading to epilepsy and thus, of potential targets for antiepileptogenic therapies. Clinical and experimental evidence suggests that inflammatory processes in the brain may critically contribute to epileptogenesis. Statins are inhibitors of cholesterol synthesis, and present pleiotropic effects that include antiinflammatory properties. We aimed the present study to test the hypothesis that atorvastatin prevents behavioral alterations and proinflammatory state in the early period after pilocarpine-induced status epilepticus. Male and female C57BL/6 mice were subjected to status epilepticus induced by pilocarpine and treated with atorvastatin (10 or 100mg/kg) for 14days. Atorvastatin slightly improved the performance of mice in the open-field and object recognition tests. In addition, atorvastatin dose-dependently decreased basal and status epilepticus induced levels of interleukin-1beta (IL-1beta), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), and interferon-gamma (INF-gamma) and increased interleukin-10 (IL-10) levels in the hippocampus and cerebral cortex. The antiinflammatory effects of atorvastatin were qualitatively identical in both sexes. Altogether, these findings extend the range of beneficial actions of atorvastatin and indicate that its antiinflammatory effects may be useful after an epileptogenic insult. PMID- 29186699 TI - Seizure-induced activation of the HPA axis increases seizure frequency and comorbid depression-like behaviors. AB - Our laboratory recently demonstrated that seizures activate the hypothalamic pituitary-adrenal (HPA) axis, increasing circulating levels of corticosterone (O'Toole et al., 2013). Given the well-established proconvulsant actions of corticosterone, we hypothesized that seizure-induced activation of the HPA axis may contribute to future seizure susceptibility. Further, since hypercortisolism is associated with depression, we propose that seizure-induced activation of the HPA axis may contribute to comorbid depression and epilepsy. To test this hypothesis, we generated mice lacking the GABAA receptor (GABAAR) delta subunit specifically in corticotropin-releasing hormone (CRH) neurons (Gabrd/Crh mice), which exhibit hyporeactivity of the HPA axis (Lee et al., 2014). Gabrd/Crh mice exhibit blunted seizure-induced elevations in corticosterone, establishing a useful tool to investigate the contribution of HPA axis dysfunction on epilepsy and associated comorbidities. Interestingly, Gabrd/Crh mice exhibit decreased acute seizure susceptibility following kainic acid (KA) administration. Furthermore, chronically epileptic Gabrd/Crh mice exhibit a decrease in both spontaneous seizure frequency and depression-like behaviors compared with chronically epileptic Cre-/- littermates. Seizure susceptibility and associated depression-like behaviors can be restored to wild type levels by treating Gabrd/Crh mice with exogenous corticosterone. Similarly, chemogenetic activation of CRH neurons in the paraventricular nucleus (PVN) is sufficient to increase seizure susceptibility; whereas, chemogenetic inhibition of CRH neurons in the PVN of the hypothalamus is sufficient to decrease seizure susceptibility and depression-like behaviors in chronically epileptic mice. These data suggest that seizure-induced activation of the HPA axis promotes seizure susceptibility and comorbid depression-like behaviors, suggesting that the HPA axis may be a novel target for seizure control. PMID- 29186695 TI - Amyloid Accumulation Drives Proteome-wide Alterations in Mouse Models of Alzheimer's Disease-like Pathology. AB - Amyloid beta (Abeta) peptides impair multiple cellular pathways and play a causative role in Alzheimer's disease (AD) pathology, but how the brain proteome is remodeled by this process is unknown. To identify protein networks associated with AD-like pathology, we performed global quantitative proteomic analysis in three mouse models at young and old ages. Our analysis revealed a robust increase in Apolipoprotein E (ApoE) levels in nearly all brain regions with increased Abeta levels. Taken together with prior findings on ApoE driving Abeta accumulation, this analysis points to a pathological dysregulation of the ApoE Abeta axis. We also found dysregulation of protein networks involved in excitatory synaptic transmission. Analysis of the AMPA receptor (AMPAR) complex revealed specific loss of TARPgamma-2, a key AMPAR-trafficking protein. Expression of TARPgamma-2 in hAPP transgenic mice restored AMPA currents. This proteomic database represents a resource for the identification of protein alterations responsible for AD. PMID- 29186700 TI - Quantifying the combined effects of land use and climate changes on stream flow and nutrient loads: A modelling approach in the Odense Fjord catchment (Denmark). AB - Water pollution and water scarcity are among the main environmental challenges faced by the European Union, and multiple stressors compromise the integrity of water resources and ecosystems. Particularly in lowland areas of northern Europe, high population density, flood protection and, especially, intensive agriculture, are important drivers of water quality degradation. In addition, future climate and land use changes may interact, with uncertain consequences for water resources. Modelling approaches have become essential to address water issues and to evaluate ecosystem management. In this work, three multi-stressor future storylines combining climatic and socio-economic changes, defined at European level, have been downscaled for the Odense Fjord catchment (Denmark), giving three scenarios: High-Tech agriculture (HT), Agriculture for Nature (AN) and Market-Driven agriculture (MD). The impacts of these scenarios on water discharge and inorganic and organic nutrient loads to the streams have been simulated using the Soil and Water Assessment Tool (SWAT). The results revealed that the scenario specific climate inputs were most important when simulating hydrology, increasing river discharge in the HT and MD scenarios (which followed the high emission 8.5 representative concentration pathway, RCP), while remaining stable in the AN scenario (RCP 4.5). Moreover, discharge was the main driver of changes in organic nutrients and inorganic phosphorus loads that consequently increased in a high emission scenario. Nevertheless, both land use (via inputs of fertilizer) and climate changes affected the nitrate transport. Different levels of fertilization yielded a decrease in the nitrate load in AN and an increase in MD. In HT, however, nitrate losses remained stable because the fertilization decrease was counteracted by a flow increase. Thus, our results suggest that N loads will ultimately depend on future land use and management in an interaction with climate changes, and this knowledge is of utmost importance for the achievement of European environmental policy goals. PMID- 29186701 TI - Evaluation of the hydrological flow paths in a gravel bed filter modeling a horizontal subsurface flow wetland by using a multi-tracer experiment. AB - In recent years, constructed wetland systems have become into focus as means of cost-efficient organic contaminant management. Wetland systems provide a highly reactive environment in which several removal pathways of organic chemicals may be present at the same time; however, specific elimination processes and hydraulic conditions are usually separately investigated and thus not fully understood. The flow system in a three dimensional pilot-scale horizontal subsurface constructed wetland was investigated applying a multi-tracer test combined with a mathematical model to evaluate the flow and transport processes. The results indicate the existence of a multiple flow system with two distinct flow paths through the gravel bed and a preferential flow at the bottom transporting 68% of tracer mass resulting from the inflow design of the model wetland system. There the removal of main contaminant chlorobenzene was up to 52% based on different calculation approaches. Determined retention times in the range of 22d to 32.5d the wetland has a heterogeneous flow pattern. Differences between simulated and measured tracer concentrations in the upper sediment indicate diffusion dominated processes due to stagnant water zones. The tracer study combining experimental evaluation with mathematical modeling demonstrated the complexity of flow and transport processes in the constructed wetlands which need to be taken into account during interpretation of the determining attenuation processes. PMID- 29186694 TI - Large-Scale Cognitive GWAS Meta-Analysis Reveals Tissue-Specific Neural Expression and Potential Nootropic Drug Targets. AB - Here, we present a large (n = 107,207) genome-wide association study (GWAS) of general cognitive ability ("g"), further enhanced by combining results with a large-scale GWAS of educational attainment. We identified 70 independent genomic loci associated with general cognitive ability. Results showed significant enrichment for genes causing Mendelian disorders with an intellectual disability phenotype. Competitive pathway analysis implicated the biological processes of neurogenesis and synaptic regulation, as well as the gene targets of two pharmacologic agents: cinnarizine, a T-type calcium channel blocker, and LY97241, a potassium channel inhibitor. Transcriptome-wide and epigenome-wide analysis revealed that the implicated loci were enriched for genes expressed across all brain regions (most strongly in the cerebellum). Enrichment was exclusive to genes expressed in neurons but not oligodendrocytes or astrocytes. Finally, we report genetic correlations between cognitive ability and disparate phenotypes including psychiatric disorders, several autoimmune disorders, longevity, and maternal age at first birth. PMID- 29186703 TI - Real world CO2 and NOx emissions from 149 Euro 5 and 6 diesel, gasoline and hybrid passenger cars. AB - In this study CO2 and NOx emissions from 149 Euro 5 and 6 diesel, gasoline and hybrid passenger cars were compared using a Portable Emissions Measurement System (PEMS). The models sampled accounted for 56% of all passenger cars sold in Europe in 2016. We found gasoline vehicles had CO2 emissions 13-66% higher than diesel. During urban driving, the average CO2 emission factor was 210.5 (sd. 47) gkm-1 for gasoline and 170.2 (sd. 34) gkm-1 for diesel. Half the gasoline vehicles tested were Gasoline Direct Injection (GDI). Euro 6 GDI engines <1.4l delivered ~17% CO2 reduction compared to Port Fuel Injection (PFI). Gasoline vehicles delivered an 86-96% reduction in NOx emissions compared to diesel cars. The average urban NOx emission from Euro 6 diesel vehicles 0.44 (sd. 0.44) gkm-1 was 11 times higher than for gasoline 0.04 (sd. 0.04) gkm-1. We also analysed two gasoline-electric hybrids which out-performed both gasoline and diesel for NOx and CO2. We conclude action is required to mitigate the public health risk created by excessive NOx emissions from modern diesel vehicles. Replacing diesel with gasoline would incur a substantial CO2 penalty, however greater uptake of hybrid vehicles would likely reduce both CO2 and NOx emissions. Discrimination of vehicles on the basis of Euro standard is arbitrary and incentives should promote vehicles with the lowest real-world emissions of both NOx and CO2. PMID- 29186702 TI - Bioaccumulation and risk assessment of organochlorine pesticides in fish from a global biodiversity hotspot: iSimangaliso Wetland Park, South Africa. AB - : Organochlorine pesticides (OCPs) have been used extensively in the eastern regions of South Africa for agricultural and malaria control purposes, yet few data exist on the local environmental and social impacts of these compounds. Such issues have become of increasing concern in the iSimangaliso World Heritage Site, where the continued use of OCPs may pose risks to several sensitive and protected species. This study was designed to examine the bioaccumulation of OCPs in two common fish species, Oreochromis mossambicus (Mozambique tilapia) and Clarias gariepinus (African sharptooth catfish) from iSimangaliso Wetland Park. These species are targeted by local subsistence fishermen and sustain substantial bird and crocodile populations. Our findings indicate widespread contamination of the aquatic environment, with SigmaOCP fish tissue concentrations in the range of 6907-8740ngg-1 lw and 2953-5874ngg-1 lw for C. gariepinus and O. mossambicus, respectively. HCHs (471-1570ngg-1 lw), DDTs (645-2399ngg-1 lw), drin-related residues (589-1960ngg-1 lw), chlor-related residues (455-2162ngg-1 lw) and endosulfans (457-1495ngg-1 lw) were detected in all tissue samples. Concentrations detected in the majority of samples exceeded European Commission maximum residue limits and a health risk assessment indicated potential dietary risk associated with exposure to heptachlor, heptachlor epoxide and dieldrin. This study represents the first investigation into OCP bioaccumulation in fish species from iSimangaliso Wetland Park. Our findings highlight the need for more detailed investigations into the bioaccumulation and ecotoxicological effects of these contaminants in the food web and the associated risks to local ecosystems and human health. CAPSULE: High levels of OCPs detected in two common fish species at iSimangaliso Wetland Park highlight potential human health and ecotoxicological threats to a globally important biodiversity conservation hotspot. PMID- 29186704 TI - CRF35-AD as the Main Circulating Genotype of Human Immunodeficiency Virus Type 1 Infection in Iran: A Phylogenetic and Demographic-Based Study. AB - Finding the predominant circulating subtype of human immunodeficiency virus type 1 (HIV-1) and surveying co-infection with other infectious viruses are crucial to making preventive decisions. To this end, 50 Iranian HIV-positive patients made up of 37 men and 13 women were selected. Most of the HIV-positive patients (70%) were intravenous drug users (IDUs), and 48 and 32% of patients were co-infected with HCV and HBV, respectively. The rate of simultaneous infection with HIV, HCV, and HBV was found to be 6%. The p17 region of the gag and the c2-v5 region of the env genes were sequenced and then clustered by phylogenetic analyses. CRF35-AD was specified as the predominant circulating subtype among different high-risk groups. In our survey, most of the patients in the IDU group had co-infections with HCV and HBV. Some possible reasons for the increased transmission risk of HIV in IDUs could be low levels of education, poor hygiene and housing conditions, and limited access to health services. PMID- 29186705 TI - Mesenchymal Stem Cell Treatment Prevents Post-Stroke Dysregulation of Matrix Metalloproteinases and Tissue Inhibitors of Metalloproteinases. AB - BACKGROUND/AIMS: Stem cell treatment is one of the potential treatment options for ischemic stroke. We recently demonstrated a protective effect of human umbilical cord blood-derived mesenchymal stem cells (HUCB-MSCs) in a rat model of ischemic stroke. The treatment attenuated apoptosis and prevented DNA damage. A collection of published studies, including several from our laboratory, indicated the induction and detrimental role for several matrix metalloproteinases (MMPs) in post-stroke brain injury. We hypothesized that the HUCB-MSCs treatment after focal cerebral ischemia prevents the dysregulation of MMPs and induces the expression of endogenous tissue inhibitors of metalloproteinases (TIMPs) to neutralize the elevated activity of MMPs. METHODS: To test our hypothesis, we administered HUCB-MSCs (0.25 million cells/animal and 1 million cells/animal) intravenously via tail vein to male Sprague-Dawley rats that were subjected to a transient (two-hour) right middle cerebral artery occlusion (MCAO) and one-day reperfusion. Ischemic brain tissues obtained from various groups of rats seven days after reperfusion were subjected to real-time PCR, immunoblot, and immunofluorescence analysis. RESULTS: HUCB-MSCs treatment prevented the induction of MMPs, which were upregulated in ischemia-induced rats that received no treatment. HUCB-MSCs treatment also prevented the induction of TIMPs expression. The extent of prevention of MMPs and TIMPs induction by HUCB-MSCs treatment is similar at both the doses tested. CONCLUSION: Prevention of stroke-induced MMPs upregulation after HUCB-MSCs treatment is not mediated through TIMPs upregulation.

PMID- 29186707 TI - Early Use of Mother's Own Raw Milk, Maternal Satisfaction, and Breastfeeding Continuation in Hospitalised Neonates: A Prospective Cohort Study. AB - BACKGROUND: Despite the critical importance of breast milk for preterm and sick neonates, there is no consensus regarding the use of raw mother's own milk (MOM) in neonatal units. OBJECTIVES: This study aimed to describe the use of raw MOM in hospitalised neonates before day 7 (early use), and to investigate: (i) related factors, (ii) maternal satisfaction, and (iii) the association with breastfeeding continuation. METHODS: This prospective cohort included 516 neonates intended to be breastfed in 2 French neonatal units. Neonates receiving raw MOM before day 7 were compared to those who did not. The association between early use of MOM and breastfeeding continuation at hospital discharge, and up to 6 months later, was measured by logistic regression. RESULTS: More than one-third (36.2%) of breastfed neonates did not receive any MOM during their first week, mainly due to organisational constraints and staff reluctance. Maternal satisfaction related to early raw MOM use was high (96%), and was coupled with a more frequent maternal feeling of being supported in breastfeeding (p = 0.003). There was a significant association between early use of MOM and breastfeeding continuation at discharge (OR 2.92, 95% CI 1.94-4.40, p < 0.0001), which persisted 6 months later (OR 2.70, 95% CI 1.21-6.03, p = 0.023). This association appeared independent in multivariable analyses (at discharge: aOR 2.03, 95% CI 1.27-3.25, p = 0.003; 6 months later: aOR 2.46, 95% CI 1.02-5.92, p = 0.045). CONCLUSION: While the early use of raw MOM in hospitalised neonates can be limited by multiple factors, it appears supportive for mothers, and might represent a simple opportunity to improve breastfeeding in neonatal units. PMID- 29186709 TI - Dynamic Profiling of Insulin Secretion and ATP Generation in Isolated Human and Mouse Islets Reveals Differential Glucose Sensitivity. AB - BACKGROUND/AIMS: Rodent islets are often used for basic science research but they do not always recapitulate signalling events in human islets. This study evaluated the glucose-dependent responses of human and mouse islets in terms of dynamic insulin secretion, metabolic coupling and the role of glucose transporters. METHODS: Glucose-induced insulin secretion from isolated mouse and human islets was profiled by perifusion and islet ATP levels were measured by chemoluminescence assay. Glucose transporter expression was determined by qPCR and western blotting. RESULTS: Human islets show a left-shifted glucose concentration-insulin secretion profile compared to mouse islets. These data are consistent with glucose transporter expression, with human islets expressing mainly GLUT1 and GLUT3, and GLUT2 being the predominant transporter in mouse islets. Using the GLUT1 inhibitor STF-31 we unveiled an important role for GLUT1 for differences in glucose-induced insulin secretion profiles observed between the two species. CONCLUSION: The high affinity of GLUT1/3 for glucose reflects the left-shifted glucose-induced insulin secretory response of human islets and the impairment of insulin secretion from human islets after STF-31 treatment indicates an important role for GLUT1 in human islet stimulus-secretion coupling. Our data provide further insight into key differences between insulin secretion regulation in mouse and human islets. PMID- 29186708 TI - Isogambogenic Acid Inhibits the Growth of Glioma Through Activation of the AMPK mTOR Pathway. AB - BACKGROUND/AIMS: Glioma is the most devastating cancer in the brain and has a poor prognosis in adults. Therefore, there is a critical need for novel therapeutic strategies for the management of glioma patients. Isogambogenic acid, an active compound extracted from the Chinese herb Garcinia hanburyi, induces autophagic cell death. METHODS: Cell viability was detected with MTT assays. Cell proliferation was assessed using the colony formation assay. Morphological changes associated with autophagy and apoptosis were tested by TEM and Hoechst staining, respectively. The apoptosis rate was measured by flow cytometry. Western blot, immunofluorescence and immunohistochemical analyses were used to detect protein expression. U87-derived xenografts were established for the examination of the effect of isogambogenic acid on glioma growth in vivo. RESULTS: Isogambogenic acid induced autophagic death in U87 and U251 cells, and blocking late-stage autophagy markedly enhanced the antiproliferative activities of isogambogenic acid. Moreover, we observed the activation of AMPK-mTOR signalling in isogambogenic acid-treated glioma cells. Furthermore, the activation of AMPK or the inhibition of mTOR augmented isogambogenic acid-induced autophagy. Inhibition of autophagy attenuated apoptosis in isogambogenic acid treated glioma cells. Finally, isogambogenic acid inhibited the growth of U87 glioma in vivo. CONCLUSION: Isogambogenic acid inhibits the growth of glioma via activation of the AMPK-mTOR signalling pathway, which may provide evidence for future clinical applications in glioma therapy. PMID- 29186710 TI - ADAMTS9 is Silenced by Epigenetic Disruption in Colorectal Cancer and Inhibits Cell Growth and Metastasis by Regulating Akt/p53 Signaling. AB - BACKGROUND/AIMS: ADAMTS (disintegrin-like and metalloproteinase with thrombospondin motifs) proteins are extracellular zinc metalloproteinases that play an important role in extracellular matrix assembly and degradation, connective tissue structuring, angiogenesis, and cell migration. Multiple studies suggest that ADAMTS proteins (e.g. ADAMTS9) can act as tumor suppressors. In gastric, esophageal, and nasopharyngeal carcinomas ADAMTS9 is frequently down regulated by promoter methylation. Whether ADAMTS9 can function as a tumor suppressor gene (TSG) in colorectal cancer is still unclear. METHODS: We performed immunohistochemistry, RT-PCR, and qRT-PCR, to examine the expression of ADAMTS9 in colorectal cancer cell lines and primary colorectal cancer tissues. Methylation-specific PCR was also carried out to investigate the promoter methylation status of ADAMTS9. We also explored the functions of ADAMTS9 in colorectal cancer cell lines through in vitro experiments. RESULTS: ADAMTS9 expression was down-requlated or silenced in 83.3% (5/6) of colorectal cancer cell lines, and frequently repressed in 65.6% (21/32) of colorectal cancer tissues. Down-regulation of ADAMTS9 was partially due to promoter methylation. Exogenous expression of ADAMTS9 in colorectal cancer cell lines inhibited cell proliferation and migration through the regulation of cell cycle and apoptosis. In addition, ADAMTS9 prevented the activation of Akt, and its downstream targets in colorectal cancer cell lines. CONCLUSION: Our findings suggest ADAMTS9 is a TSG in colorectal cancer.

Its diploid chromosome number is 2n = 46 with 12 meta-, 10 submeta-, 16 subtelo-, and 8 acrocentric chromosomes and a fundamental number of FN = 84. An XX/XY sex chromosome system was identified. Mapping of 18S rDNA correlated with the nucleolus organizer regions (Ag-NORs) in the short arms of the 2 X chromosomes in females and in the Y chromosome in males. C-banding revealed heterochromatin in the centromeric regions of all chromosomes, except for pair 3. Prominent sex chromosome-specific heterochromatin amplification was observed, covering the short arms of the Y chromosome almost entirely. FISH with telomeric and tropomyosin (tpm1) sequences, respectively, revealed terminal signals in all chromosomes. The analysis of extended DNA fibers confirmed the colocalization and the interspersed pattern of the telomeric and tpm1 sequences. Thus, this study highlights the remarkable evolutionary dynamism presented by the Amazonian puffer fish regarding the differentiation of a heteromorphic XY sex chromosome system and a particular sex-specific amplification of rDNA sites. This is the first record of such an association in the Tetraodontidae family. PMID- 29186713 TI - Phosphatidylcholine Causes Lipolysis and Apoptosis in Adipocytes through the Tumor Necrosis Factor Alpha-Dependent Pathway. AB - A phosphatidylcholine (PPC) formulation has been used to treat cellulite; however, its underlying mechanism of action remains unclear. In this study, we demonstrated that PPC induces lipolysis and apoptosis in adipocytes, and evaluated a possible tumor necrosis factor alpha (TNFalpha)-dependent pathway, whereby PPC exerts these effects. For in vitro study, fully differentiated 3T3-L1 cells, mouse adipocytes were treated with various concentrations of PPC and cell apoptosis and lipolysis were assayed. For in vivo experiments, mice fed on a high fat diet for 8 weeks were injected twice to abdominal subcutaneous fat tissues of either vehicle or PPC. We found that PPC induced lipolysis and apoptosis dose dependently in fully differentiated 3T3-L1 cells. In addition, PPC augmented both expression and release of TNFalpha in a dose-dependent fashion. Induction of TNFalpha by PPC was associated with the stimulation of nuclear factor kappa B (NFkappaB)-mediated transcriptional activity. Small interfering RNA (siRNA) mediated suppression of NFkappaB abrogated the effect of PPC on TNFalpha secretion. Suppression of TNFalpha with specific siRNA abrogated the effects of PPC on lipolysis and apoptosis. Through in vivo experiments, we demonstrated that PPC injection not only stimulated the local lipolysis and apoptosis, resulting in weight loss, but also induced TNFalpha mRNA expression and neutrophil infiltration. Furthermore, PPC injection prevented lipogenesis and suppressed the mRNA -expression of adipokines (such as adiponectin and leptin), due to the down sizing of adipocytes. In conclusion, we suggest that PPC induces lipolysis and apoptosis in adipocytes through TNFalpha-dependent pathways. PMID- 29186712 TI - Reproductive Hormones and Their Receptors May Affect Lung Cancer. AB - BACKGROUND/AIMS: In contrast to men, women have experienced a rapid increase in lung cancer mortality. Numerous studies have found that the sex differences in lung cancer are due to reproductive hormones. Experiments in female mice with and without ovariectomy were performed to explore the possible mechanism by which sex hormones (and their receptors) influence lung cancer. METHODS: Twenty-four female C57BL/6 mice aged 56-62 days were randomly divided into the ovariectomized group and the control group. In the ovariectomized group, the bilateral ovaries were removed via the dorsal approach, while the control group underwent a sham operation with bilateral ovarian fat resection at the same sites. After 3 weeks of recovery, Lewis lung cancer cells were transplanted into these mice by subcutaneous inoculation of a tumour cell suspension to establish the ovariectomized lung cancer model. Beginning on the 6th day after subcutaneous inoculation, mouse weight and transplanted tumour volume were measured every 3 days. After 3 weeks, all the mice were killed by cervical dislocation, and we measured the tumour weight. Mouse serum and tumour tissues were removed. Then, the serum levels of E2 (oestradiol) and T (testosterone) were detected by ELISA; the protein expression levels of AR (androgen receptor), ERalpha (oestrogen receptor alpha) and ERbeta (oestrogen receptor beta) were detected by Western Blot and IHC (immunohistochemistry); and the mRNA expression levels of AR, ERalpha and ERbeta were detected by qRT-PCR (quantitative real-time polymerase chain reaction) in the ovariectomized and control groups. RESULTS: Compared with the control group, both mouse weight and transplanted tumour volume increased rapidly in the ovariectomized group, and the transplanted tumour weight was significantly heavier in the ovariectomized group (1.83+/-0.40 and 3.13+/-0.43, P<0.05). E2 and T serum levels decreased exponentially in the ovariectomized group, while the E2/T ratio increased compared with the control group (E2: 55.88+/-11.45 and 78.21+/-9.37; T: 0.82+/-0.14 and 1.46+/-0.16; ratio: 69.62+/ 14.43+/-29.81 and 52.22+/-5.42; all P<0.05). The Western blot and IHC results indicated that AR, ERalpha and ERbeta protein expression levels were obviously higher in transplanted tumour and lung tissues from the ovariectomized group, with particular increases in ERbeta in transplanted tumour tissue and in ERalpha in lung tissue. The PCR results also showed markedly higher mRNA expression levels of AR, ERalpha and ERbeta in the ovariectomized group, and in particular, ERbeta in transplanted tumour tissue and ERalpha in lung tissue were significantly increased in the ovariectomized group. CONCLUSION: Ovariectomy decreased E2 and T serum levels and increased the E2/T ratio in mice, and this imbalance in the internal environment promoted the growth of transplanted tumours. Sex hormone disorder not only promoted transplanted tumour growth but also significantly reduced the protein and mRNA expression levels of sex hormone receptors. The metabolism of E2 and T may affect the growth, proliferation and metabolism of lung cancer cells, and the mechanism by which sex hormones and their receptors influence lung cancer is worthy of further research. PMID- 29186714 TI - Enhanced Immunological Tolerance by HLA-G1 from Neural Progenitor Cells (NPCs) Derived from Human Embryonic Stem Cells (hESCs). AB - BACKGROUND: Despite the great potential of utilizing human embryonic stem cells (hESCs)-derived cells as cell source for transplantation, these cells were often rejected during engraftment by the immune system due to adaptive immune response. METHODS: We first evaluated HLA-G expression level in both hESCs and differentiated progenitor cells. After that, we generated modified hESC lines that over-express HLA-G1 using lentiviral infection with the construct contains both HLA-G1 and GFP tag. The lentivirus was first produced by co-transfecting HLA G1 expressing lentiviral vector together with packaging vectors into packaging cell line 293T. Then the produced virus was used for the infection of selected hESC lines. We characterized the generated cell lines phenotype, including pluripotency and self-renewal abilities, as well as immune tolerance ability by mixed lymphocyte reaction (MLR) and cytotoxicity assays. RESULTS: Although the hESCs do not express high levels of HLA-G1, over-expression of HLA-G1 in hESCs still retains their stem cell characteristics as determined by retaining the expression levels of OCT4 and SOX2, two critical transcriptional factors for stem cell function. Furthermore, the HLA-G1 overexpressing hESCs retain the self renewal and pluripotency characteristics of stem cells, which can differentiate into different types of cells, including pigment cells, smooth muscle cells, epithelia-like cells, and NPCs. After differentiation, the differentiated cells including NPCs retain the high levels of HLA-G1 protein. In comparison with conventional NPCs, these HLA-G1 positive NPCs have enhanced immune tolerance ability. CONCLUSIONS: Ectopic expression of HLA-G1, a non-classical major histocompatibility complex class I (MHC I) antigen that was originally discovered involving in engraftment tolerance during pregnancy, can enhance the immunological tolerance in differentiated neural progenitor cells (NPCs). Our study shows that stably overexpressing HLA-G1 in hESCs might be a feasible strategy for enhancing the engraftment of NPCs during transplantation. PMID- 29186715 TI - Thulium Vaporesection of the Prostate and Thulium Vapoenucleation of the Prostate: A Retrospective Bicentric Matched-Paired Comparison with 24-Month Follow-Up. AB - INTRODUCTION: To evaluate the intermediate-term outcomes of thulium vapoenucleation of the prostate (ThuVEP) and thulium vaporesection of the prostate (ThuVaRP) in patients with benign prostate obstruction (BPO). MATERIALS AND METHODS: A bicentric retrospective matched-paired comparison of patients treated by ThuVEP (n = 80) or ThuVaRP (n = 80) was performed. The patients were preoperatively assessed with International Prostate Symptom Score (IPSS), quality of life (QoL), post-void residual urine (PVR), maximum urinary flow rate (Qmax), prostatespecific antigen (PSA) and re-evaluated at 12- and 24-month follow-up. RESULTS: Median prostate volume was 65 mL and not different between the groups. The immediate re-operation rate was significantly different between ThuVEP and ThuVaRP (5 vs. 0%, p <= 0.0434). IPSS, QoL, Qmax and PVR had improved significantly compared to preoperative assessment in both groups at 12- and 24 month follow-up (p <= 0.001). Median Qmax (18.2 vs. 21.0 mL/s) and PVR (29.4 vs. 0 mL) were significantly different between ThuVEP and ThuVaRP at 24-month follow up (p <= 0.001), while IPSS and QoL showed no differences between the groups. However, the PSA reduction was significantly higher after ThuVEP compared to ThuVaRP (78.93 vs. 23.39%, p <= 0.006) at 24-month follow-up. CONCLUSIONS: ThuVEP and ThuVaRP are safe and efficacious procedures for patients with BPO. Although the peri-operative re-intervention rates were lower after ThuVaRP, the low PSA reduction rate after ThuVaRP at 24-month follow-up favours the ThuVEP procedure.

Xiamen, China, December 1-3, 2017: A Selection of Abstracts. PMID- 29186716 TI - Muller Cell-Derived PEDF Mediates Neuroprotection via STAT3 Activation. AB - : Background/ Aims: This study was performed to reveal signaling pathways exploited by pigment epithelium-derived factor (PEDF) derived from retinal (glial) Muller cells to protect retinal ganglion cells (RGCs) from cell death. METHODS: The survival of RGCs was determined in the presence of conditioned culture media (MCM) from or in co-cultures with Muller cells. The significance of PEDF-induced STAT3 activation was evaluated in viability assays and using Western blotting analyses and siRNA-transfected cells. RESULTS: Secreted mediators of Muller cells increased survival of RGCs under normoxia or hypoxia to a similar degree as of PEDF- or IL-6-exposed cells. PEDF and MCM induced an increased STAT3 activation in RGCs and R28 cells, and neutralization of PEDF in MCM attenuated STAT3 activation. Inhibition of STAT3 reduced PEDF-promoted survival of RGCs. Similar to IL-6, PEDF induced STAT3 activation, acting in a dose-dependent manner via the PEDF receptor (PEDF-R) encoded by the PNPLA2 gene. Ablation of PEDF-R attenuated MCM-induced STAT3 activation and compromised the viability of PEDF exposed R28 cells. CONCLUSIONS: Muller cells are an important source of PEDF, which promotes RGC survival through STAT3 activation and, at least in part, via PEDF-R. Enhancing the secretory function of Muller cells may be useful to promote RGC survival in retinal neurodegenerative diseases. PMID- 29186718 TI - Interferon-Stimulated Genes as Enhancers of Antiviral Innate Immune Signaling. AB - The ability of a host to curb a viral infection is heavily reliant on the effectiveness of an initial antiviral innate immune response, resulting in the upregulation of interferon (IFN) and, subsequently, IFN-stimulated genes (ISGs). ISGs serve to mount an antiviral state within a host cell, and although the specific antiviral function of a number of ISGs has been characterized, the function of many of these ISGs remains to be determined. Recent research has uncovered a novel role for a handful of ISGs, some of them directly induced by IFN regulatory factor 3 in the absence of IFN itself. These ISGs, most with potent antiviral activity, are also able to augment varying arms of the innate immune response to viral infection, thereby strengthening this response. This new understanding of the role of ISGs may, in turn, help the recent advancement of novel therapeutics aiming to augment innate signaling pathways in an attempt to control viral infection and pathogenesis. PMID- 29186719 TI - Single-Incision Laparoscopic Splenectomy for an Unruptured Aneurysm of the Splenic Artery. AB - OBJECTIVE: We describe our experience of single-incision laparoscopic splenectomy (SILS) for an unruptured aneurysm of the splenic artery. CLINICAL PRESENTATION AND INTERVENTION: A 73-year-old woman was diagnosed as having a splenic aneurysm which grew from 14 to 22 mm in diameter within 2 years. Due to a contrast agent allergy, transcatheter arterial embolization could not be performed; therefore, SILS was performed with a 4-cm Z-shaped incision. The operative time and intraoperative blood loss were 132 min and 27 mL, respectively. The patient was discharged 4 days after surgery. CONCLUSION: In selected cases, SILS is a suitable and safe procedure for an unruptured aneurysm of the splenic artery. PMID- 29186720 TI - Archaeal and Bacterial Community Structure in an Anaerobic Digestion Reactor (Lagoon Type) Used for Biogas Production at a Pig Farm. AB - Biogas production from animal waste is an economically viable way to reduce environmental pollution and produce valuable products, i.e., methane and a nutrient-rich organic waste product. An anaerobic digestion reactor for biogas production from pig waste was sampled at the entrance, middle (digestion chamber), and exit of a digester, while the bacterial and archaeal community structure was studied by 16S rRNA gene metagenomics. The number of bacterial operational taxonomic units (OTU)-97% was 3-7 times larger than that of archaeal ones. Bacteria and Archaea found in feces of animals (e.g., Clostridiaceae, Lachnospiraceae, Ruminococcaceae, Methanosarcina, Methanolobus, Methanosaeta, and Methanospirillum) dominated the entrance of the digester. The digestion chamber was dominated by anaerobic sugar-fermenting OP9 bacteria and the syntrophic bacteria Candidatus Cloacamonas (Waste Water of Evry 1; WWE1). The methanogens dominant in the digestion chamber were the acetoclastic Methanosaeta and the hydrogenothrophic Methanoculleus and Methanospirillum. Similar bacterial and archaeal groups that dominated in the middle of the digestion chamber were found in the waste that left the digester. Predicted functions associated with degradation of xenobiotic compounds were significantly different between the sampling locations. The microbial community found in an anaerobic digestion reactor loaded with pig manure contained microorganisms with biochemical capacities related to the 4 phases of methane production. PMID- 29186722 TI - IL-33 Expression in Chronic Rhinosinusitis with Nasal Polyps and Its Relationship with Clinical Severity. AB - BACKGROUND: Chronic rhinosinusitis (CRS) is a heterogeneous disease characterized by epithelial inflammation and tissue eosinophilic infiltration. Interleukin-33 (IL-33) is a key inflammatory cytokine that mediates eosinophilic infiltration. OBJECTIVE: The aim of our study was to investigate the expression and role of IL 33 in eosinophilic CRS with nasal polyps (ECRSwNP) and in noneosinophilic CRS with nasal polyps (nECRSwNP), and to analyze their correlation with clinical severity. METHODS: The study enrolled 25 patients with ECRSwNP, 27 patients with nECRSwNP, and 12 control subjects, based on immunohistochemical staining. Protein and mRNA expressions of IL-33 in sinus mucosal samples were determined by immunohistochemistry and real-time polymerase chain reaction. Sino-Nasal Outcome Test-20 (SNOT-20) score, visual analog scale (VAS) score, endoscopy score, and computed tomography (CT) score were assessed preoperatively. RESULTS: IL-33 expression levels in the CRSwNP group were significantly higher than those in the control group (p < 0.01), especially in the ECRSwNP group (p < 0.05). There were no significant differences between the ECRSwNP and nECRSwNP groups with respect to SNOT-20 score, VAS score, endoscopy score, or CT score. IL-33 mRNA expression showed a positive correlation with the number of eosinophils (p < 0.05) and endoscopy score (p < 0.05) but not with VAS score and CT score. CONCLUSION: IL-33 expression plays an important role in patients with CRSwNP. No significant differences were observed between the ECRSwNP and nECRSwNP groups with respect to SNOT-20 score, VAS score, endoscopy score, or CT score. IL-33 expression was correlated with eosinophil counts and endoscopy score. PMID- 29186723 TI - Optical Coherence Tomography Angiography in Optic Nerve Drusen. AB - AIM: To determine the efficacy of optical coherence tomography angiography (OCT A) in diagnosing optic nerve head flow impairment in patients with optic nerve drusen. METHODS: Patients affected by optic-nerve head drusen (ONHD) attending the Eye Clinic of the Federico II University of Naples were enrolled in this prospective case series between October 2015 and October 2016. Each patient underwent evaluation of best corrected visual acuity (BCVA), Goldman applanation tonometry, slit-lamp biomicroscopy, fundus examination, standard visual-field testing (perimetry), spectral domain (SD)-OCT and OCT-A. RESULTS: Thirteen patients (6 females and 7 males with a mean age of 22.05 +/- 7.54 years) with ONHD (19 eyes) were enrolled. Mean BCVA was 0.16 +/- 0.21 LogMar and mean intraocular pressure was 15.68 +/- 1.66 mm Hg. The control group constituted 16 individuals (24 eyes). Both ganglion cell complex (GCC) and retinal nerve fiber layer (RNFL) parameters were lower in patients than in controls. Similarly, the flow index (U = 134, p = 0.021) and vessel density (U = 90, p = 0.001) were significantly lower in eyes affected by ONHD than in normal eyes. Visual-field parameters did not differ between the 2 groups. GCC parameters were significantly correlated with OCT-A parameters (p < 0.05). No correlation was found between RNFL and OCT-A parameters. CONCLUSIONS: Our data suggest that OCT-A could be an objective method, helpful in the analysis of flow changes in patients with ONHD. PMID- 29186721 TI - n-3 Polyunsaturated Fatty Acids and Cardiovascular Disease: Principles, Practices, Pitfalls, and Promises - A Contemporary Review. AB - Amidst voluminous literature, inconsistencies and opposing results have confused rather than clarified cardiologists' ability to assess the potential benefits of n-3 polyunsaturated fatty acids (n-3 PUFA). In perspective, there are common themes that emerge from n-3 PUFA studies, even as imperfect as they may be. The approach taken was to identify and unite these themes into a manageable, cohesive, evidence-based, yet useful synthesis. In all reviews and meta-analyses, the selection of component studies and assumptions influences outcomes. This overarching principle must be combined with the totality of the data, particularly when evidence is incompletely understood and gaps in knowledge must be bridged. Both the older literature and the most recent rigorous meta-analyses indicate that n-3 PUFA are highly pleiotropic agents with many documented positive physiological effects. Concordance among preclinical, observational, randomized clinical trials and meta-analyses is impressive. These agents have modest, statistically significant benefits which accrue over time. Given their favorable safety profile, a risk reduction of about 10% justifies their potential use in cardiovascular disease. PMID- 29186724 TI - [Establishing Prevention Reporting in Bavaria - Concept, Implementation and First Results]. AB - BACKGROUND: Bavaria is currently embarking on the endeavour of building up systematic prevention reporting. Prevention reporting is meant to support the implementation of the Bavarian Prevention Plan and the German Prevention Law and to further the ongoing development in the field of health promotion and health related prevention in Bavaria. GOALS: Prevention reporting in Bavaria aims to draw on general health reporting and complement it with specific prevention related data taking into special consideration the Bavarian Prevention Plan. Particularly, data on prevention-amenable health determinants, prevention interventions, prevention spending and on indicators related to the targets of the Bavarian Prevention Plan are meant to be included. Periodic reporting will allow ongoing monitoring and the observation of trends. The reporting system will encompass shorter publications for the general public as well as more extensive reports for an expert audience. Where possible, data will be reported not only Bavaria wide but also on a smaller regional level to support local action. IMPLEMENTATION AND FIRST RESULTS: An extensive stocktaking of prevention and health promotion activities in Bavaria in 2014/2015 as well as a survey of the partner organisations in the Bavarian Prevention Alliance in 2016 presented an overview of the prevention scene in Bavaria. A core indicator set to support the implementation of the Bavarian Prevention Plan was developed in 2016 and a first short data brochure for the public was published. A comprehensive compilation of prevention-related data and a Bavarian prevention report are planned for 2017 and 2018. CONCLUSIONS: Like health reporting, prevention reporting, as conceptualised in Bavaria, presents overview data and thus allows a monitoring of prevention. For specific planning or evaluation purposes, it needs to be supplemented by more in-depth analyses. Current challenges include the development of valid, prevention-specific indicators, the generation of an empiric database and the attempt of a coordinated approach amongst the federal states within Germany. PMID- 29186725 TI - [Screening of executive functions in patients with Parkinson's disease using the new rapid test PAL-5]. AB - Parkinson's disease (PD) is the second most prevalent chronic neurodegenerative disorder worldwide, following Alzheimer's disease. Along with the characteristic motor symptoms of the disorder, especially bradykinesia, cognitive deficits can often be found prior to the onset of the disorder. These mainly concern executive functioning. To detect cognitive deficits at an early stage, initial screening procedures are recommended. The new cognitive rapid test Paarassoziationslernen-5 ("PAL-5") has been developed to detect the most prevalent cognitive symptoms - namely executive impairments - of PD patients. It consists of a direct recall of five incompatible and newly jointed word pairs (capitals vs. countries), an intermediate formal lexical word fluency task ("FAS-Test") and a delayed recall. Thereby, the three major executive functioning processes are tested: cognitive flexibility, inhibition and memory. In the department of neurology of the University Clinic of Cologne, the PAL-5 was completed by 154 PD patients, 115 participants with cognitive deficits without a PD diagnosis and 115 controls (N = 384) between 2014 and 2016. For purposes of retest reliability determination, another 42 controls were examined from February to July 2017, with a four-month time interval between the initial and second test. Highly significant group differences have been found. PD patients and cognitive impaired participants scored significantly lower than the control group. A comparison of PD patients and cognitively impaired participants did not reveal significant group differences. Additionally, a moderate to high correlation between PAL-5 and MMST as well as PAL-5 and PANDA was found (respectively p < .001). An ROC analysis of the PAL-5 total score of PD patients with a score lower than 11 showed an AUC of .91. Therefore, a cut-off of <= 10 seems to be practicable to detect cognitive deficits - especially executive functioning deficits and memory impairments - in PD patients. It has been shown that cognitive flexibility, inhibition and memory is a short useful combination for a screening procedure of PD patients.

AB - Inner dealing with the question of death as well as death anxiety accompany human beings from the beginning, which is reflected by the different philosophical and religious positions. It is obvious that work on this issue is sparse in the field of psychiatric disorders. Due to the few literatures it can however be assumed that death anxiety plays a greater role within the changed thoughts and feelings of psychiatric patients, whose intensity we probably determine and assess in non sufficient manner yet. The terms are defined and the problematic of ego destruction in patients with schizophrenia as expression of death anxiety is specifically discussed. Furthermore, the few studies about death anxiety in psychiatric disorders, its psychodynamics and approaches of the so-called terror management theory are presented besides other aspects. The current state of literature is presented, points out the importance of this issue for our field and wants to initiate more research on this topic.

AB - Background Laser haemorrhoidoplasty (LHP) with the 1470 nm diode laser in minimally invasive surgery for advanced haemorrhoid disease has been studied with respect to clinical variables, such as pain and complications, and intraoperative characteristics such as mucopexia, number of treated knots and energy consumed per patient. The study also included patient satisfaction, symptom relevance and cost effectiveness. Patients and Methods Between November 2010 and November 2016, 497 patients (age 55 +/- 14 years) were submitted to laser haemorrhoidoplasty with a 1470 nm diode laser in the centre for minimally invasive proctology in Siegen District Hospital. All operated patients were included in the study. Perioperative clinical and technical data up to 6 weeks and follow-up data up to 6 months were analysed prospectively. Results The mean duration of operation was 14 min (+/- 5.2). A mean of 2.7 knots of 2.7 size were treated per patient. The mean postoperative pain was 2.5/10 (VAS). Long-term symptom relevance was 86%, and patient satisfaction 91%. Complications occurred in 49 patients (9.9%): bleeding 1.8%, infection 1%, urine retention 1.8%, oedema/thrombosis/prolapse 6.6%. 8.8% of patients suffered a relapse within 6 months. There were significant differences in pain on the day of the operation, and the parameters mucopexia, 3 treated segments and energy level > 500 J (p < 0.05). Complications were more common when mucopexia was performed, with 3 treated knots and energy consumed per patient > 500 J. The only significant difference was for energy level > 500 J (p < 0.05). Conclusion LHP is a safe, low pain and minimally invasive surgical procedure with long-term good patient acceptance and satisfaction and is suited for routine work. The energy applied should be reduced to a minimum. Complication rates are largely comparable with those of other minimally invasive conventional methods. Additional prospective studies must be performed, particularly in comparison to the Parks method, which gives similar functional results. With circular confluent findings, LHP cannot replace stapler hemorrhoidopexia. PMID- 29186746 TI - [Interdisciplinary Acute Medical Rehabilitation after Sepsis - A Retrospective Analysis]. AB - Background Surviving sepsis may have consequences of high impact for the patients' further life regarding functioning in mobility and activities of daily living, among other fields. Patients consecutively have a great need of rehabilitation interventions beginning with early mobilization in the Intensive Care Unit ICU. Acute medical rehabilitation is a concept of early rehabilitation still in the acute care hospital, normally beginning after a direct transferal from the ICU. Its aim is to improve the patients' functioning in mobility and activities of daily living (ADL) to enable further post-acute rehabilitation interventions. Methods In this retrospective analysis a sample of patients who received acute medical rehabilitation after surviving a sepsis or severe sepsis was followed. The study targeted the question if basic functions of mobility and ADL could be improved by acute medical rehabilitation. Furthermore, the need for aid supply was evaluated, as well as the type of discharge or transferal after acute care. Results The increase of mobility and ADL capability before and after acute medical rehabilitation was highly significant (p<0.001 each) and showed very large effect sizes (d=1.3, 1.4 respectively). Aid supply was organized for 92% of patients. A majority of patients could receive consecutive post-acute rehabilitation after re-gaining function. Discussion The data shows the enormous gain in functioning that can be reached with an acute medical rehabilitation intervention after ICU treatment of sepsis. PMID- 29186747 TI - [Volume Growth of Inpatient Treatments for Spinal Disease - Analysis of German Nationwide Hospital Discharge Data from 2005 to 2014]. AB - BACKGROUND: Marked volume growth of inpatient treatments for spinal disease has been observed since diagnosis related groups (DRG) were introduced as payment for inpatient services in Germany. This study aims to analyse this increase by population and stratified by types of treatment. MATERIAL AND METHODS: Using German nationwide hospital discharge data (DRG statistics), inpatient treatments for spinal disease with or without surgery were identified. Trends in case numbers were analysed from 2005 to 2014 with consideration of demographic changes, in order to explore which age groups and which types of treatment are affected by volume growth. RESULTS: In 2014 (2005), 289 000 (177 000) inpatient treatments with surgery and 463 000 (287 000) treatments without surgery were identified. After adjusting for demographic factors, treatments with and without surgery exhibited a relative volume growth of + 50%. This increase affected higher age groups and women, in particular. Depending on the type of treatment, very different degrees of volume growth were observed. For example, disc surgeries adjusted for demographic change increased by about + 5%, whereas spinal fusion and vertebral replacement surgeries, kypho-/vertebroplasties and decompression of the spine more than doubled. Within the non-surgically treated cases, local pain therapies of the spine increased after adjustment for demographic changes by about + 142%. The conservatively treated cases showed a demographically adjusted increase of + 22%. CONCLUSION: Apart from demographic changes, this analysis cannot resolve the underlying causes of volume growth in treatments for spinal disease. However, the stratified analysis of various subgroups may help to classify these developments in a more differentiated manner. The results may support a more targeted debate about potential over- or misallocation of inpatient services in this area. PMID- 29186748 TI - [Impact of microphone position on sound localization in cochlear implant users]. AB - OBJECTIVE: The delivery of directional cues of a hearing device microphone are highly dependent on the position of the microphones. The aim of this work was the evaluation of different microphone positions with regard to the transmission of interaural time and level differences as well as the spectral characteristics and its impact on the localization abilities. METHODS: Head-related transfer functions of 30 subjects were measured with three different omnidirectional microphones at different positions: in the pinna (ITP), behind the ear (BTE), at the entrance of the ear canal (EEC). Sound localization abilities of 12 bilateral CI users was assessed for the microphone positions ITP and BTE. RESULTS: Only the microphone positions in the ear (ITP, EEC) could sample the spectral cues of the pinna. However, the positioning of the microphone inside of the pinna did not significantly improve sound localization abilities compared to BTE microphones. For sound incidence from rear significantly less front-back confusions were achieved with the microphone inside of the pinna. CONCLUSION: The microphone position in the pinna showed only a slight improvement in sound localization compared with BTE microphones in CI users. A precondition for better sound localization abilities is the improvement of the delivery of temporal and spectral fine structure cues in CI systems. PMID- 29186749 TI - [Microvascular reconstruction of the larynx following total laryngectomy]. AB - Total laryngectomy still is a standard procedure for the treatment of advanced laryngeal or hypopharyngeal carcinoma. The unavoidable loss of voice may lead to serious impairments in quality of life. The most common technique of voice restoration is the tracheal-esophageal puncture combined with the application of a voice prosthesis. Laryngeal reconstruction with a radial forearm flap represents a possible surgical method of voice restoration. This study is a mono center retrospective analysis of patients receiving a so-called laryngoplasty after total laryngectomy between 2006 and 2015, focusing on long-term functional outcome and complications. 39 patients were included. Sufficient phonation was possible in 77 %, finger-free speaking was achieved in 62 %. Exclusion of irradiated patients revealed a rehabilitation rate of 91 %. The most common early complication was cervical hematoma in 15 %, whereas no loss of flap was assessed. Stenosis of the laryngoplasty was seen in 7 cases, mainly post-irradiation. The rate of successful voice restoration is equal in both, laryngoplasty and voice prosthesis patients. However, voice quality is better after surgical reconstruction. Complications induced by the voice prosthesis, which may be severe in some cases, were not seen in the study group. Furthermore, life-long support by an ENT specialist regarding voice prosthesis exchange is not necessary. Assuming correct choice of candidates, laryngoplasty is a sufficient method for voice restoration after laryngectomy. PMID- 29186751 TI - More on Ethics and Scholarship. PMID- 29186752 TI - A Novel Method to Improve the Anticancer Activity of Natural-Based Hydroxyapatite against the Liver Cancer Cell Line HepG2 Using Mesoporous Magnesia as a Micro Carrier. AB - Micro-carriers are the best known vehicles to transport different kinds of drugs to achieve high impact. In this study, mesoporous magnesium oxide has been harnessed as a micro-carrier to encapsulate the anticancer candidate drug natural based cubic hydroxyapatite (HAP). HAP@MgO composites with different HAP loading (0-60 wt %), were prepared by a hydrothermal treatment method using triethanol amine as a template. The characterization of the prepared composites were achieved by using XRD, Raman spectroscopy, FTIR and SEM. Characterization data confirm the formation of sphere-like structures of MgO containing HAP particles. It was observed that the size of the spheres increased with HAP loading up to 40 wt %, then collapsed. Furthermore, the anticancer property of the prepared composites was evaluated against the HepG2 liver cancer cell line. The HAP@MgO composites exhibited higher activity than neat MgO or HAP. The 20 wt % of HAP was the optimum loading to control cell proliferation by inducing apoptosis. Apoptosis was determined by typical apoptotic bodies produced by the cell membrane. PMID- 29186754 TI - Portable Electronic Nose Based on Electrochemical Sensors for Food Quality Assessment. AB - The steady increase in global consumption puts a strain on agriculture and might lead to a decrease in food quality. Currently used techniques of food analysis are often labour-intensive and time-consuming and require extensive sample preparation. For that reason, there is a demand for novel methods that could be used for rapid food quality assessment. A technique based on the use of an array of chemical sensors for holistic analysis of the sample's headspace is called electronic olfaction. In this article, a prototype of a portable, modular electronic nose intended for food analysis is described. Using the SVM method, it was possible to classify samples of poultry meat based on shelf-life with 100% accuracy, and also samples of rapeseed oil based on the degree of thermal degradation with 100% accuracy. The prototype was also used to detect adulterations of extra virgin olive oil with rapeseed oil with 82% overall accuracy. Due to the modular design, the prototype offers the advantages of solutions targeted for analysis of specific food products, at the same time retaining the flexibility of application. Furthermore, its portability allows the device to be used at different stages of the production and distribution process. PMID- 29186755 TI - Climate Modelling Shows Increased Risk to Eucalyptus sideroxylon on the Eastern Coast of Australia Compared to Eucalyptus albens. AB - Aim: To identify the extent and direction of range shift of Eucalyptus sideroxylon and E. albens in Australia by 2050 through an ensemble forecast of four species distribution models (SDMs). Each was generated using four global climate models (GCMs), under two representative concentration pathways (RCPs). Location: Australia. Methods: We used four SDMs of (i) generalized linear model, (ii) MaxEnt, (iii) random forest, and (iv) boosted regression tree to construct SDMs for species E. sideroxylon and E. albens under four GCMs including (a) MRI CGCM3, (b) MIROC5, (c) HadGEM2-AO and (d) CCSM4, under two RCPs of 4.5 and 6.0. Here, the true skill statistic (TSS) index was used to assess the accuracy of each SDM. Results: Results showed that E. albens and E. sideroxylon will lose large areas of their current suitable range by 2050 and E. sideroxylon is projected to gain in eastern and southeastern Australia. Some areas were also projected to remain suitable for each species between now and 2050. Our modelling showed that E. sideroxylon will lose suitable habitat on the western side and will not gain any on the eastern side because this region is one the most heavily populated areas in the country, and the populated areas are moving westward. The predicted decrease in E. sideroxylon's distribution suggests that land managers should monitor its population closely, and evaluate whether it meets criteria for a protected legal status. Main conclusions: Both Eucalyptus sideroxylon and E. albens will be negatively affected by climate change and it is projected that E. sideroxylon will be at greater risk of losing habitat than E. albens. PMID- 29186756 TI - Robust Vehicle Detection in Aerial Images Based on Cascaded Convolutional Neural Networks. AB - Vehicle detection in aerial images is an important and challenging task. Traditionally, many target detection models based on sliding-window fashion were developed and achieved acceptable performance, but these models are time consuming in the detection phase. Recently, with the great success of convolutional neural networks (CNNs) in computer vision, many state-of-the-art detectors have been designed based on deep CNNs. However, these CNN-based detectors are inefficient when applied in aerial image data due to the fact that the existing CNN-based models struggle with small-size object detection and precise localization. To improve the detection accuracy without decreasing speed, we propose a CNN-based detection model combining two independent convolutional neural networks, where the first network is applied to generate a set of vehicle like regions from multi-feature maps of different hierarchies and scales. Because the multi-feature maps combine the advantage of the deep and shallow convolutional layer, the first network performs well on locating the small targets in aerial image data. Then, the generated candidate regions are fed into the second network for feature extraction and decision making. Comprehensive experiments are conducted on the Vehicle Detection in Aerial Imagery (VEDAI) dataset and Munich vehicle dataset. The proposed cascaded detection model yields high performance, not only in detection accuracy but also in detection speed. PMID- 29186757 TI - Nitrogen-Doped Carbon Quantum Dots as Fluorescent Probes for Sensitive and Selective Detection of Nitrite. AB - Nitrites are the upstream precursors of the carcinogenic nitrosamines, which are widely found in the natural environment and many food products. It is important to develop a simple and sensitive sensor for detecting nitrites. In this work, a fluorescence probe based on nitrogen-doped carbon quantum dots (N-CQDs) was developed for the sensitive and selective determination of nitrites. At pH 2, the fluorescence of N-CQDs can be selectively quenched by nitrite due to the fact N nitroso compounds can be formed in the reaction of amide groups with nitrous acid, which results in fluorescence static quenching. Under optimal conditions, fluorescence intensity quenching upon addition of nitrite gives a satisfactory linear relationship covering the linear range of 0.2-20 MUM, and the limit of detection (LOD) is 40 nM. Moreover, this method has been successfully applied to the determination of nitrites in tap water, which indicates its great potential for monitoring of nitrites in environmental samples. PMID- 29186758 TI - Simultaneous Determination of Multiple Classes of Hydrophilic and Lipophilic Components in Shuang-Huang-Lian Oral Liquid Formulations by UPLC-Triple Quadrupole Linear Ion Trap Mass Spectrometry. AB - The Shuang-Huang-Lian (SHL) oral liquid is a combined herbal prescription used in the treatment of acute upper respiratory tract infection, acute bronchitis and pneumonia. Multiple constituents are considered to be responsible for the therapeutic effects of SHL. However, the quantitation of the multi-components from multiple classes is still unsatisfactory because of the high complexity of constituents in SHL. In this study, an accurate, rapid, and specific UPLC-MS/MS method was established for simultaneous quantification of 18 compounds from multiple classes in SHL oral liquid formulations. Chromatographic separation was performed on a HSS T3 (1.8 MUm, 2.1 mm * 100 mm) column, using a gradient mobile phase system of 0.1% formic acid in acetonitrile and 0.1% formic acid in water at a flow rate of 0.2 mL.min-1; the run time was 23 min. The MS was operated in negative electrospray ionization (ESI-) for analysis of 18 compounds using multiple reaction monitoring (MRM) mode. UPLC-ESI--MRM-MS/MS method showed good linear relationships (R2 > 0.999), repeatability (RSD < 3%), precisions (RSD < 3%) and recovery (84.03-101.62%). The validated method was successfully used to determine multiple classes of hydrophilic and lipophilic components in the SHL oral liquids. Finally, principal component analysis (PCA) was used to classify and differentiate SHL oral liquid samples attributed to different manufacturers of China. The proposed UPLC-ESI--MRM-MS/MS coupled with PCA has been elucidated to be a simple and reliable method for quality evaluation of SHL oral liquids. PMID- 29186759 TI - Effect of Two Different Doses of Vitamin D Supplementation on Metabolic Profiles of Insulin-Resistant Patients with Polycystic Ovary Syndrome. AB - This study was carried out to evaluate the effects of vitamin D supplementation on the metabolic profiles of insulin-resistant subjects with polycystic ovary syndrome (PCOS). This randomized double-blind, placebo-controlled trial was conducted on 90 insulin-resistant women with PCOS. Participants were randomly assigned to three groups to intake either 4000 IU of vitamin D or 1000 IU of vitamin D or placebo (n = 30 each group) daily for 12 weeks. Vitamin D supplementation (4000 IU), compared with vitamin D (1000 IU) and placebo, led to significant reductions in total testosterone (-0.2 +/- 0.2 vs. -0.1 +/- 0.6 and +0.1 +/- 0.2 ng/mL, respectively, p = 0.02), free androgen index (FAI) (-0.06 +/- 0.12 vs. -0.02 +/- 0.12 and +0.004 +/- 0.04, respectively, p = 0.04), hirsutism ( 1.1 +/- 1.1 vs. -0.8 +/- 1.2 and -0.1 +/- 0.4, respectively, p = 0.001) and high sensitivity C-reactive protein (hs-CRP) (-0.7 +/- 1.4 vs. -0.5 +/- 0.9 and +0.5 +/- 2.4 mg/L, respectively, p = 0.01). In addition, we found significant elevations in mean change of sex hormone-binding globulin (SHBG) (+19.1 +/- 23.0 vs. +4.5 +/- 11.0 and +0.7 +/- 10.4 nmol/L, respectively, p < 0.001) and total antioxidant capacity (TAC) (+130 +/- 144 vs. +33 +/- 126 and -36 +/- 104 mmol/L, respectively, p < 0.001) in the high-dose vitamin D group compared with low-dose vitamin D and placebo groups. Overall, high-dose vitamin D administration for 12 weeks to insulin-resistant women with PCOS had beneficial effects on total testosterone, SHBG, FAI, serum hs-CRP and plasma TAC levels compared with low dose vitamin D and placebo groups. PMID- 29186753 TI - Intrinsic Disorder in Proteins with Pathogenic Repeat Expansions. AB - Intrinsically disordered proteins and proteins with intrinsically disordered regions have been shown to be highly prevalent in disease. Furthermore, disease causing expansions of the regions containing tandem amino acid repeats often push repetitive proteins towards formation of irreversible aggregates. In fact, in disease-relevant proteins, the increased repeat length often positively correlates with the increased aggregation efficiency and the increased disease severity and penetrance, being negatively correlated with the age of disease onset. The major categories of repeat extensions involved in disease include poly glutamine and poly-alanine homorepeats, which are often times located in the intrinsically disordered regions, as well as repeats in non-coding regions of genes typically encoding proteins with ordered structures. Repeats in such non coding regions of genes can be expressed at the mRNA level. Although they can affect the expression levels of encoded proteins, they are not translated as parts of an affected protein and have no effect on its structure. However, in some cases, the repetitive mRNAs can be translated in a non-canonical manner, generating highly repetitive peptides of different length and amino acid composition. The repeat extension-caused aggregation of a repetitive protein may represent a pivotal step for its transformation into a proteotoxic entity that can lead to pathology. The goals of this article are to systematically analyze molecular mechanisms of the proteinopathies caused by the poly-glutamine and poly alanine homorepeat expansion, as well as by the polypeptides generated as a result of the microsatellite expansions in non-coding gene regions and to examine the related proteins. We also present results of the analysis of the prevalence and functional roles of intrinsic disorder in proteins associated with pathological repeat expansions. PMID- 29186760 TI - Effects of A 60 Hz Magnetic Field of Up to 50 milliTesla on Human Tremor and EEG: A Pilot Study. AB - Humans are surrounded by sources of daily exposure to power-frequency (60 Hz in North America) magnetic fields (MFs). Such time-varying MFs induce electric fields and currents in living structures which possibly lead to biological effects. The present pilot study examined possible extremely low frequency (ELF) MF effects on human neuromotor control in general, and physiological postural tremor and electroencephalography (EEG) in particular. Since the EEG cortical mu rhythm (8-12 Hz) from the primary motor cortex and physiological tremor are related, it was hypothesized that a 60 Hz MF exposure focused on this cortical region could acutely modulate human physiological tremor. Ten healthy volunteers (age: 23.8 +/- 4 SD) were fitted with a MRI-compatible EEG cap while exposed to 11 MF conditions (60 Hz, 0 to 50 mTrms, 5 mTrms increments). Simultaneously, physiological tremor (recorded from the contralateral index finger) and EEG (from associated motor and somatosensory brain regions) were measured. Results showed no significant main effect of MF exposure conditions on any of the analyzed physiological tremor characteristics. In terms of EEG, no significant effects of the MF were observed for C1, C3, C5 and CP1 electrodes. However, a significant main effect was found for CP3 and CP5 electrodes, both suggesting a decreased mu rhythm spectral power with increasing MF flux density. This is however not confirmed by Bonferroni corrected pairwise comparisons. Considering both EEG and tremor findings, no effect of the MF exposure on human motor control was observed. However, MF exposure had a subtle effect on the mu-rhythm amplitude in the brain region involved in tactile perception. Current findings are to be considered with caution due to the small size of this pilot work, but they provide preliminary insights to international agencies establishing guidelines regarding electromagnetic field exposure with new experimental data acquired in humans exposed to high mT-range MFs. PMID- 29186761 TI - Characterization of a Sea Buckthorn Extract and Its Effect on Free and Encapsulated Lactobacillus casei. AB - Probiotics are bacteria that can provide health benefits to consumers and are suitable to be added to a variety of foods. In this research, viability of immobilized Lactobacillus casei in alginate with or without sea buckthorn lipid extract were studied during heat treatment and with an in vitro gastrointestinal model. The characterization of the lipid extract was also done using the UV-Vis spectrometry (UV-Vis), high-performance liquid chromatography photodiode array detection method (HPLC-PDA), gas chromatography coupled with mass spectrometry (GS-MS) and Cryo scanning electron microscopy (Cryo-SEM). During heat treatment, the entrapped probiotic cells proved high viability (>6 CFU log/g), even at temperatures above 50 degrees C. The rich in monounsaturated fatty acids sea buckthorn fraction improved the in vitro digestion passage regarding the probiotic viability. The survival of the probiotic cells was 15% higher after 2 h in the acidic medium of the simulated gastric fluid in the sample where L. casei was encapsulated with the sea buckthorn extract compared with the samples where no extract was added. Thus, this approach may be effective for the future development of probiotic-supplemented foods as foods with health welfare for the consumers. PMID- 29186763 TI - PTP1B Inhibitors from the Entomogenous Fungi Isaria fumosorosea. AB - Protein tyrosine phosphatase 1B (PTP1B) is implicated as a negative regulator of insulin receptor (IR) signaling and a potential drug target for the treatment of type II diabetes and other associated metabolic syndromes. Thus, small molecule inhibitors of PTP1B can be considered as an attractive approach for the design of new therapeutic agents of type II diabetes and cancer diseases. In a continuing search for new PTP1B inhibitors, a new tetramic acid possessing a rare pyrrolidinedione skeleton named fumosorinone A (1), together with five known ones 2-6 were isolated from the entomogenous fungus Isaria fumosorosea. The structures of 2-6 were elucidated by extensive spectroscopic analysis. Fumosorinone A (1) and beauvericin (6) showed significant PTP1B inhibitory activity with IC50 value of 3.24 MUM and 0.59 MUM. PMID- 29186762 TI - Grip Strength as an Indicator of Health-Related Quality of Life in Old Age-A Pilot Study. AB - Over the last century life expectancy has increased dramatically nearly all over the world. This dramatic absolute and relative increase of the old aged people component of the population has influenced not only population structure but also has dramatic implications for the individuals and public health services. The aim of the present pilot study was to examine the impact of physical well-being assessed by hand grip strength and social factors estimated by social contact frequency on health-related quality of life among 22 men and 41 women ranging in age between 60 and 94 years. Physical well-being was estimated by hand grip strength, data concerning subjective wellbeing and health related quality of life were collected by personal interviews based on the WHOQOL-BREF questionnaires. Number of offspring and intergenerational contacts were not related significantly to health-related quality of life, while social contacts with non-relatives and hand grip strength in contrast had a significant positive impact on health related quality of life among old aged men and women. Physical well-being and in particular muscle strength-estimated by grip strength-may increase health-related quality of life and is therefore an important source for well-being during old age. Grip strength may be used as an indicator of health-related quality of life. PMID- 29186764 TI - Update on Phytochemistry and Pharmacology of Naturally Occurring Resveratrol Oligomers. AB - Resveratrol oligomers (REVs), a major class of stilbenoids, are biosynthesized by regioselective oxidative coupling of two to eight units of resveratrol monomer. Due to their unique structures and pleiotropic biological activities, natural product chemists are increasingly focusing on REVs in the last few decades. This study presents a detailed and thorough examination of REVs, including chemical structures, natural resources, and biological activities, during the period of 2010-2017. Ninety-two new REVs compounds, including 39 dimers, 23 trimers, 13 tetramers, six resveratrol monomers, six hexamers, four pentamers, and one octamer, have been reported from the families of Dipterocarpaceae, Paeoniaceae, Vitaceae, Leguminosae, Gnetaceae, Cyperaceae, Polygonaceae Gramineae, and Poaceae. Amongst these families, Dipterocarpaceae, with 50 REVs, accounts for the majority, and seven genera of Dipterocarpaceae are involved, including Vatica, Vateria, Shorea, Hopea, Neobalanocarpus, Dipterocarpus, and Dryobalanops. These REVs have shown a wide range of bioactivities. Pharmacological studies have mainly focused on potential efficacy on tumors, bacteria, Alzheimer's disease, cardiovascular diseases, and others. The information updated in this review might assist further research and development of novel REVs as potential therapeutic agents. PMID- 29186765 TI - To Group or Not to Group? Good Practice for Housing Male Laboratory Mice. AB - It is widely recommended to group-house male laboratory mice because they are 'social animals', but male mice do not naturally share territories and aggression can be a serious welfare problem. Even without aggression, not all animals within a group will be in a state of positive welfare. Rather, many male mice may be negatively affected by the stress of repeated social defeat and subordination, raising concerns about welfare and also research validity. However, individual housing may not be an appropriate solution, given the welfare implications associated with no social contact. An essential question is whether it is in the best welfare interests of male mice to be group- or singly housed. This review explores the likely impacts-positive and negative-of both housing conditions, presents results of a survey of current practice and awareness of mouse behavior, and includes recommendations for good practice and future research. We conclude that whether group- or single-housing is better (or less worse) in any situation is highly context-dependent according to several factors including strain, age, social position, life experiences, and housing and husbandry protocols. It is important to recognise this and evaluate what is preferable from animal welfare and ethical perspectives in each case. PMID- 29186767 TI - A Microwave Microfluidic Sensor Based on a Dual-Mode Resonator for Dual-Sensing Applications. AB - In this paper, we propose a novel microwave microfluidic sensor with dual-sensing capability. The sensor is based on a dual-mode resonator that consists of a folded microstrip line loaded with interdigital lines and a stub at the plane of symmetry. Due to the specific configuration, the resonator exhibits two entirely independent resonant modes, which allows simultaneous sensing of two fluids using a resonance shift method. The sensor is designed in a multilayer configuration with the proposed resonator and two separated microfluidic channels-one intertwined with the interdigital lines and the other positioned below the stub. The circuit has been fabricated using low-temperature co-fired ceramics technology and its performance was verified through the measurement of its responses for different fluids in the microfluidic channels. The results confirm the dual-sensing capability with zero mutual influence as well as good overall performance. Besides an excellent potential for dual-sensing applications, the proposed sensor is a good candidate for application in mixing fluids and cell counting. PMID- 29186766 TI - Autophagy in Measles Virus Infection. AB - Autophagy is a biological process that helps cells to recycle obsolete cellular components and which greatly contributes to maintaining cellular integrity in response to environmental stress factors. Autophagy is also among the first lines of cellular defense against invading microorganisms, including viruses. The autophagic destruction of invading pathogens, a process referred to as xenophagy, involves cytosolic autophagy receptors, such as p62/SQSTM1 (Sequestosome 1) or NDP52/CALCOCO2 (Nuclear Dot 52 KDa Protein/Calcium Binding And Coiled-Coil Domain 2), which bind to microbial components and target them towards growing autophagosomes for degradation. However, most, if not all, infectious viruses have evolved molecular tricks to escape from xenophagy. Many viruses even use autophagy, part of the autophagy pathway or some autophagy-associated proteins, to improve their infectious potential. In this regard, the measles virus, responsible for epidemic measles, has a unique interface with autophagy as the virus can induce multiple rounds of autophagy in the course of infection. These successive waves of autophagy result from distinct molecular pathways and seem associated with anti- and/or pro-measles virus consequences. In this review, we describe what the autophagy-measles virus interplay has taught us about both the biology of the virus and the mechanistic orchestration of autophagy. PMID- 29186768 TI - Monitoring the Wobbe Index of Natural Gas Using Fiber-Enhanced Raman Spectroscopy. AB - The fast and reliable analysis of the natural gas composition requires the simultaneous quantification of numerous gaseous components. To this end, fiber enhanced Raman spectroscopy is a powerful tool to detect most components in a single measurement using a single laser source. However, practical issues such as detection limit, gas exchange time and background Raman signals from the fiber material still pose obstacles to utilizing the scheme in real-world settings. This paper compares the performance of two types of hollow-core photonic crystal fiber (PCF), namely photonic bandgap PCF and kagome-style PCF, and assesses their potential for online determination of the Wobbe index. In contrast to bandgap PCF, kagome-PCF allows for reliable detection of Raman-scattered photons even below 1200 cm-1, which in turn enables fast and comprehensive assessment of the natural gas quality of arbitrary mixtures. PMID- 29186769 TI - Models in the Research Process of Psoriasis. AB - Psoriasis is an ancient, universal chronic skin disease with a significant geographical variability, with the lowest incidence rate at the equator, increasing towards the poles. Insights into the mechanisms responsible for psoriasis have generated an increasing number of druggable targets and molecular drugs. The development of relevant in vitro and in vivo models of psoriasis is now a priority and an important step towards its cure. In this review, we summarize the current cellular and animal systems suited to the study of psoriasis. We discuss the strengths and limitations of the various models and the lessons learned. We conclude that, so far, there is no one model that can meet all of the research needs. Therefore, the choice model system will depend on the questions being addressed. PMID- 29186770 TI - The Evaluation of Pro-Cognitive and Antiamnestic Properties of Berberine and Magnoflorine Isolated from Barberry Species by Centrifugal Partition Chromatography (CPC), in Relation to QSAR Modelling. AB - Civilization diseases associated with memory disorders are important health problems occurring due to a prolonged life span. The manuscript shows the results of an in vivo study targeting the emergence of two drug candidates with anti amnestic properties. The preceding quantitative structure-activity relationship (QSAR) studies provided information on the ability of berberine and magnoflorine to cross the blood-brain barrier (BBB). In the light of these findings, both compounds were purified from crude plant extracts of barberries: berberine-from Berberis siberica using a method published earlier, and magnoflorine-from Berberis cretica by centrifugal partition chromatography (solvent system: ethyl acetate:butanol:water-0.6:1.5:3 v/v/v). Both the compounds were evaluated for their memory enhancing and scopolamine inhibitory properties in an in vivo passive avoidance (PA) test on mice towards short-term and long-term memory. Cognition enhancing properties were observed at the following doses: 5 mg/kg (i.p.) for berberine and 20 mg/kg (i.p.) for magnoflorine. In addition, both the tested isoquinolines with the co-administered scopolamine were found to block long-term but not short-term memory impairment. No influence on the locomotor activity was observed for the tested doses. The results confirmed a marked central activity of magnoflorine and showed the necessity to lower the dosage of berberine. Optimized purification conditions have been elaborated for magnoflorine. PMID- 29186771 TI - Surface Acoustic Wave (SAW) for Chemical Sensing Applications of Recognition Layers. AB - Surface acoustic wave (SAW) resonators represent some of the most prominent acoustic devices for chemical sensing applications. As their frequency ranges from several hundred MHz to GHz, therefore they can record remarkably diminutive frequency shifts resulting from exceptionally small mass loadings. Their miniaturized design, high thermal stability and possibility of wireless integration make these devices highly competitive. Owing to these special characteristics, they are widely accepted as smart transducers that can be combined with a variety of recognition layers based on host-guest interactions, metal oxide coatings, carbon nanotubes, graphene sheets, functional polymers and biological receptors. As a result of this, there is a broad spectrum of SAW sensors, i.e., having sensing applications ranging from small gas molecules to large bio-analytes or even whole cell structures. This review shall cover from the fundamentals to modern design developments in SAW devices with respect to interfacial receptor coatings for exemplary sensor applications. The related problems and their possible solutions shall also be covered, with a focus on emerging trends and future opportunities for making SAW as established sensing technology.

PMID- 29186773 TI - Metabolic Perturbations in a Bacillus subtilis clpP Mutant during Glucose Starvation. AB - Proteolysis is essential for all living organisms to maintain the protein homeostasis and to adapt to changing environmental conditions. ClpP is the main protease in Bacillus subtilis, and forms complexes with different Clp ATPases. These complexes play crucial roles during heat stress, but also in sporulation or cell morphology. Especially enzymes of cell wall-, amino acid-, and nucleic acid biosynthesis are known substrates of the protease ClpP during glucose starvation. The aim of this study was to analyze the influence of a clpP mutation on the metabolism in different growth phases and to search for putative new ClpP substrates. Therefore, B. subtilis 168 cells and an isogenic ?clpP mutant were cultivated in a chemical defined medium, and the metabolome was analyzed by a combination of 1H-NMR, HPLC-MS, and GC-MS. Additionally, the cell morphology was investigated by electron microscopy. The clpP mutant showed higher levels of most glycolytic metabolites, the intermediates of the citric acid cycle, amino acids, and peptidoglycan precursors when compared to the wild-type. A strong secretion of overflow metabolites could be detected in the exo-metabolome of the clpP mutant. Furthermore, a massive increase was observed for the teichoic acid metabolite CDP-glycerol in combination with a swelling of the cell wall. Our results show a recognizable correlation between the metabolome and the corresponding proteome data of B. subtilisclpP mutant. Moreover, our results suggest an influence of ClpP on Tag proteins that are responsible for teichoic acids biosynthesis. PMID- 29186774 TI - A Method for Measurement of Nonlinearity of Laser Interferometer Based on Optical Frequency Tuning. AB - A method for measuring the nonlinearity of laser interferometer using optical frequency tuning technique is presented in this paper. The basic principle of this method is to make the fractional part of an interference fringe change by tuning the laser frequency and determining the nonlinearity of interferometer by comparing the fractional fringe change measured by the interferometer to that calculated from the laser frequency change. An experimental interferometric system with a wavelength tunable laser source is set up and the nonlinearity of the interferometer is measured. Since it does not require the precise displacement mechanism to produce the optical path difference change, this method is more convenient to use and may achieve a higher accuracy than the conventional measurement methods. The nonlinearity of the arbitrary interferometric phase can be measured by changing the laser frequency with this method. Experiments results have shown that the repeatability of nonlinearity measurement is less than 0.2 nm. This method can be applied to interferometry-based high precision dimensional measurements, such as coordinate measurement and displacement sensor calibration. PMID- 29186775 TI - Identifying the Epitope Regions of Therapeutic Antibodies Based on Structure Descriptors. AB - Therapeutic antibodies are widely used for disease detection and specific treatments. However, as an exogenous protein, these antibodies can be detected by the human immune system and elicit a response that can lead to serious illnesses. Therapeutic antibodies can be engineered through antibody humanization, which aims to maintain the specificity and biological function of the original antibodies, and reduce immunogenicity. However, the antibody drug effect is synchronously reduced as more exogenous parts are replaced by human antibodies. Hence, a major challenge in this area is to precisely detect the epitope regions in immunogenic antibodies and guide point mutations of exogenous antibodies to balance both humanization level and drug effect. In this article, the latest dataset of immunoglobulin complexes was collected from protein data bank (PDB) to discover the spatial features of immunogenic antibody. Furthermore, a series of structure descriptors were generated to characterize and distinguish epitope residues from non-immunogenic regions. Finally, a computational model was established based on structure descriptors, and results indicated that this model has the potential to precisely predict the epitope regions of therapeutic antibodies. With rapid accumulation of immunoglobulin complexes, this methodology could be used to improve and guide future antibody humanization and potential clinical applications.

AB - The detection of hydrogen sulfide (H2S) and ethanediamine, toxic gases that are emitted from industrial processes, is important for health and safety. An optical sensor, based on the absorption spectrum of tetrakis(4-nitrophenyl)porphyrin (TNPP) immobilized in a Nafion membrane (Nf) and deposited onto an optical waveguide glass slide, has been developed for the detection of these gases. Responses to analytes were compared for sensors modified with TNPP and Nf-TNPP composites. Among them, Nf-TNPP exhibited significant responses to H2S and ethanediamine. The analytical performance characteristics of the Nf-TNPP-modified sensor were investigated and the response mechanism is discussed in detail. The sensor exhibited excellent reproducibilities, reversibilities, and selectivities, with detection limits for H2S and ethanediamine of 1 and 10 ppb, respectively, and it is a promising candidate for use in industrial sensing applications.

(Rhamnaceae) is comprised of about 170 species that are mainly distributed in tropical to subtropical regions, with few in the temperate zone. Several Ziziphus fruit tree species are important energy, nutrient, and medicinal resources for human populations, particularly for those living in rural regions. To date, limited genomic information is available for this genus. Here, we assembled the complete chloroplast genomes of four best known Ziziphus species, i.e., Ziziphus jujuba, Ziziphus acidojujuba, Ziziphus mauritiana, and Ziziphus spina-christi, based on the Illumina Paired-end sequencing method. The chloroplast genomes of the four Ziziphus species are all very similar to one another, and exhibit structural, gene content, and order characteristics that are similar to other flowering plants. The entire chloroplast genome encodes 113 predicted unique genes (85 protein-coding genes, 8 rRNA, and 37 tRNA), 17 of which are duplicated in the inverted repeat regions. Rich single sequence repeats loci (217) were detected in Z. jujuba and 106 SSR loci, composed of A/T, displayed polymorphism across the four species by comparative genomic analysis. We found only four genes under positive selection between Z. jujuba and Z. acidojujuba, and two genes for Z. mauritiana vs. Z. spina-christi, respectively, while half of the 78 protein-coding genes experienced positive selection between the two groups. Phylogenetic analyses revealed that Ziziphus (Rhamnaceae) was sister to Elaeagnaceae, and the four species of Ziziphus were clustered into two groups (Z. jujuba and Z. acidojujuba, Z. mauritiana and Z. spina-christi). Our results provide genomic resources for intrageneric classifications of Ziziphus, and valuable genetic markers for investigating the population genetics and biogeography of closely related Ziziphus species.

AB - The clavine alkaloids produced by the fungi of the Aspergillaceae and Arthrodermatacea families differ from the ergot alkaloids produced by Claviceps and Neotyphodium. The clavine alkaloids lack the extensive peptide chain modifications that occur in lysergic acid derived ergot alkaloids. Both clavine and ergot alkaloids arise from the condensation of tryptophan and dimethylallylpyrophosphate by the action of the dimethylallyltryptophan synthase. The first five steps of the biosynthetic pathway that convert tryptophan and dimethylallyl-pyrophosphate (DMA-PP) in chanoclavine-1-aldehyde are common to both clavine and ergot alkaloids. The biosynthesis of ergot alkaloids has been extensively studied and is not considered in this article. We focus this review on recent advances in the gene clusters for clavine alkaloids in the species of Penicillium, Aspergillus (Neosartorya), Arthroderma and Trychophyton and the enzymes encoded by them. The final products of the clavine alkaloids pathways derive from the tetracyclic ergoline ring, which is modified by late enzymes, including a reverse type prenyltransferase, P450 monooxygenases and acetyltransferases. In Aspergillus japonicus, a alpha-ketoglutarate and Fe2+ dependent dioxygenase is involved in the cyclization of a festuclavine-like unknown type intermediate into cycloclavine. Related dioxygenases occur in the biosynthetic gene clusters of ergot alkaloids in Claviceps purpurea and also in the clavine clusters in Penicillium species. The final products of the clavine alkaloid pathway in these fungi differ from each other depending on the late biosynthetic enzymes involved. An important difference between clavine and ergot alkaloid pathways is that clavine producers lack the enzyme CloA, a P450 monooxygenase, involved in one of the steps of the conversion of chanoclavine-1 aldehyde into lysergic acid. Bioinformatic analysis of the sequenced genomes of the Aspergillaceae and Arthrodermataceae fungi showed the presence of clavine gene clusters in Arthroderma species, Penicillium roqueforti, Penicillium commune, Penicillium camemberti, Penicillium expansum, Penicillium steckii and Penicillium griseofulvum. Analysis of the gene clusters in several clavine alkaloid producers indicates that there are gene gains, gene losses and gene rearrangements. These findings may be explained by a divergent evolution of the gene clusters of ergot and clavine alkaloids from a common ancestral progenitor six genes cluster although horizontal gene transfer of some specific genes may have occurred more recently. PMID- 29186779 TI - The Effect of Red Palm Oil on Vitamin A Deficiency: A Meta-Analysis of Randomized Controlled Trials. AB - Red palm oil (RPO) has been investigated for preventing or alleviating vitamin A deficiency (VAD). Previous data has offered inconclusive and inconsistent results about the effects of RPO in patients with VAD. Our objective was to undertake a meta-analysis to assess the effects of RPO in preventing VAD in the population. After conducting a comprehensive literature search, nine randomized controlled trials (RCTs) were included. Overall, when trial results were pooled, the results indicated that RPO reduced the risk of VAD (relative risk (RR) (95% confidence interval (CI)) = 0.55 (0.37, 0.82), p = 0.003), increasedserum retinol levels in both children (p < 0.00001) and adults (p = 0.002), and increased beta-carotene levels (p = 0.01). However, RPO supplementation did not have a significant overall effect on serum alpha-carotene levels (p = 0.06), body weight (p = 0.45), and haemoglobin levels (p = 0.72). The results also showed that low level of PRO intake (<=8 g RPO) could increase serum retinol concentrations whereas PRO intake above 8 g did not lead to further increase of serum retinol concentrations. This meta-analysis demonstrated that RPO might be effective for preventing or alleviating VAD. PMID- 29186780 TI - Bullying and Cyberbullying: Their Legal Status and Use in Psychological Assessment. AB - Bullying and cyberbullying have severe psychological and legal consequences for those involved. However, it is unclear how or even if previous experience of bullying and cyberbullying is considered in mental health assessments. Furthermore, the relevance and effectiveness of current legal solutions has been debated extensively, resulting in a desire for a specific legislation. The purpose of this study is to investigate the psychological and legal components of bullying and cyberbullying. This is a qualitative research that includes interviews with five practitioner psychologists and four lawyers in the United Kingdom (UK). Thematic analysis revealed three main themes. One theme is related to the definition, characteristics, and impact of bullying and cyberbullying and the need for more discussion among the psychological and legal professions. Another theme is related to current professional procedures and the inclusion of questions about bullying and cyberbullying in psychological risk assessments. The third theme emphasised the importance of intervention through education. Two key messages were highlighted by the lawyers: ample yet problematic legislation exists, and knowledge will ensure legal success. The study recommends the necessity of performing revisions in the clinical psychological practices and assessments, and the legal policies regarding bullying and cyberbullying. In addition to improving legal success, this will reduce bullying prevalence rates, psychological distress, and psychopathology that can be comorbid or emerge as a result of this behaviour. PMID- 29186781 TI - The Heterologous Expression of the p22 RNA Silencing Suppressor of the Crinivirus Tomato Chlorosis Virus from Tobacco Rattle Virus and Potato Virus X Enhances Disease Severity but Does Not Complement Suppressor-Defective Mutant Viruses. AB - To counteract host antiviral RNA silencing, plant viruses express suppressor proteins that function as pathogenicity enhancers. The genome of the Tomato chlorosis virus (ToCV) (genus Crinivirus, family Closteroviridae) encodes an RNA silencing suppressor, the protein p22, that has been described as having one of the longest lasting local suppressor activities when assayed in Nicotiana benthamiana. Since suppression of RNA silencing and the ability to enhance disease severity are closely associated, we analyzed the effect of expressing p22 in heterologous viral contexts. Thus, we studied the effect of the expression of ToCV p22 from viral vectors Tobacco rattle virus (TRV) and Potato virus X (PVX), and from attenuated suppressor mutants in N. benthamiana plants. Our results show that although an exacerbation of disease symptoms leading to plant death was observed in the heterologous expression of ToCV p22 from both viruses, only in the case of TRV did increased viral accumulation occur. The heterologous expression of ToCV p22 could not complement suppressor-defective mutant viruses. PMID- 29186782 TI - Forging a Frailty-Ready Healthcare System to Meet Population Ageing. AB - The beginning of the 21st century has seen health systems worldwide struggling to deliver quality healthcare amidst challenges posed by ageing populations. The increasing prevalence of frailty with older age and accompanying complexities in physical, cognitive, social and psychological dimensions renders the present modus operandi of fragmented, facility-centric, doctor-based, and illness centered care delivery as clearly unsustainable. In line with the public health framework for action in the World Health Organization's World Health and Ageing Report, meeting these challenges will require a systemic reform of healthcare delivery that is integrated, patient-centric, team-based, and health-centered. These reforms can be achieved through building partnerships and relationships that engage, empower, and activate patients and their support systems. To meet the challenges of population ageing, Singapore has reorganised its public healthcare into regional healthcare systems (RHSs) aimed at improving population health and the experience of care, and reducing costs. This paper will describe initiatives within the RHS frameworks of the National Health Group (NHG) and the Alexandra Health System (AHS) to forge a frailty-ready healthcare system across the spectrum, which includes the well healthy ("living well"), the well unhealthy ("living with illness"), the unwell unhealthy ("living with frailty"), and the end-of-life (EoL) ("dying well"). For instance, the AHS has adopted a community centered population health management strategy in older housing estates such as Yishun to build a geographically-based care ecosystem to support the self management of chronic disease through projects such as "wellness kampungs" and "share-a-pot". A joint initiative by the Lien Foundation and Khoo Teck Puat Hospital aims to launch dementia-friendly communities across the island by building a network comprising community partners, businesses, and members of the public. At the National Healthcare Group, innovative projects to address the needs of the frail elderly have been developed in the areas of: (a) admission avoidance through joint initiatives with long-term care facilities, nurse-led geriatric assessment at the emergency department and geriatric assessment clinics; (b) inpatient care, such as the Framework for Inpatient care of the Frail Elderly, orthogeriatric services, and geriatric surgical services; and (c) discharge to care, involving community transitional care teams and the development of community infrastructure for post-discharge support; and an appropriate transition to EoL care. In the area of EoL care, the National Strategy for Palliative Care has been developed to build an integrated system to: provide care for frail elderly with advance illnesses, develop advance care programmes that respect patients' choices, and equip healthcare professionals to cope with the challenges of EoL care. PMID- 29186783 TI - Altered Leukocyte Sphingolipid Pathway in Breast Cancer. AB - Sphingolipid metabolism pathway is essential in membrane homeostasis, and its dysfunction has been associated with favorable tumor microenvironment, disease progression, and chemotherapy resistance. Its major components have key functions on survival and proliferation, with opposing effects. We have profiled the components of the sphingolipid pathway on leukocytes of breast cancer (BC) patients undergoing chemotherapy treatment and without, including the five sphingosine 1-phosphate (S1P) receptors, the major functional genes, and cytokines, in order to better understand the S1P signaling in the immune cells of these patients. To the best of our knowledge, this is the first characterization of the sphingolipid pathway in whole blood of BC patients. Skewed gene profiles favoring high SPHK1 expression toward S1P production during BC development was observed, which was reversed by chemotherapy treatment, and reached similar levels to those found in healthy donors. Such levels were also correlated with high levels of TNF-alpha. Our data revealed an important role of the sphingolipid pathway in immune cells in BC with skewed signaling of S1P receptors, which favored cancer development even under chemotherapy, and may probably be a trigger of cancer resistance. Thus, these molecules must be considered as a target pathway for combined BC therapeutics. PMID- 29186784 TI - Species-Specific Inactivation of Triosephosphate Isomerase from Trypanosoma brucei: Kinetic and Molecular Dynamics Studies. AB - Human African Trypanosomiasis (HAT), a disease that provokes 2184 new cases a year in Sub-Saharan Africa, is caused by Trypanosoma brucei. Current treatments are limited, highly toxic, and parasite strains resistant to them are emerging. Therefore, there is an urgency to find new drugs against HAT. In this context, T. brucei depends on glycolysis as the unique source for ATP supply; therefore, the enzyme triosephosphate isomerase (TIM) is an attractive target for drug design. In the present work, three new benzimidazole derivatives were found as TbTIM inactivators (compounds 1, 2 and 3) with an I50 value of 84, 82 and 73 uM, respectively. Kinetic analyses indicated that the three molecules were selective when tested against human TIM (HsTIM) activity. Additionally, to study their binding mode in TbTIM, we performed a 100 ns molecular dynamics simulation of TbTIM-inactivator complexes. Simulations showed that the binding of compounds disturbs the structure of the protein, affecting the conformations of important domains such as loop 6 and loop 8. In addition, the physicochemical and drug-like parameters showed by the three compounds suggest a good oral absorption. In conclusion, these molecules will serve as a guide to design more potent inactivators that could be used to obtain new drugs against HAT. PMID- 29186786 TI - A Radar-Based Smart Sensor for Unobtrusive Elderly Monitoring in Ambient Assisted Living Applications. AB - Continuous in-home monitoring of older adults living alone aims to improve their quality of life and independence, by detecting early signs of illness and functional decline or emergency conditions. To meet requirements for technology acceptance by seniors (unobtrusiveness, non-intrusiveness, and privacy preservation), this study presents and discusses a new smart sensor system for the detection of abnormalities during daily activities, based on ultra-wideband radar providing rich, not privacy-sensitive, information useful for sensing both cardiorespiratory and body movements, regardless of ambient lighting conditions and physical obstructions (through-wall sensing). The radar sensing is a very promising technology, enabling the measurement of vital signs and body movements at a distance, and thus meeting both requirements of unobtrusiveness and accuracy. In particular, impulse-radio ultra-wideband radar has attracted considerable attention in recent years thanks to many properties that make it useful for assisted living purposes. The proposed sensing system, evaluated in meaningful assisted living scenarios by involving 30 participants, exhibited the ability to detect vital signs, to discriminate among dangerous situations and activities of daily living, and to accommodate individual physical characteristics and habits. The reported results show that vital signs can be detected also while carrying out daily activities or after a fall event (post fall phase), with accuracy varying according to the level of movements, reaching up to 95% and 91% in detecting respiration and heart rates, respectively. Similarly, good results were achieved in fall detection by using the micro-motion signature and unsupervised learning, with sensitivity and specificity greater than 97% and 90%, respectively. PMID- 29186785 TI - Screening In Vitro Targets Related to Diabetes in Herbal Extracts from Peru: Identification of Active Compounds in Hypericum laricifolium Juss. by Offline High-Performance Liquid Chromatography. AB - This study investigates in vitro targets related to diabetes in 30 herbal extracts from Peru, for the first time, using alpha-glucosidase, aldose reductase (AR) inhibitory assays and 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) scavenging assays. Among the 30 herbal extracts, Hypericum laricifolium Juss. (HL) was the herb which showed more than 50% inhibition in all assays, presenting 97.2 +/- 2.0%, 56.9 +/- 5.6%, 81.9 +/- 2.5%, and 58.8 +/- 4.6% inhibition for the alpha-glucosidase, AR, DPPH, and ABTS assays, respectively. Finally, six bioactive compounds, namely, protocatechuic acid, chlorogenic acid, caffeic acid, kaempferol 3-O-glucuronide, quercetin, and kaempferol were identified in HL by offline high-performance liquid chromatography (HPLC). Quercetin exhibited the strongest inhibition in all enzyme assays and the strongest antioxidant activity. The results suggest that HL shows great potential for the complementary treatment of diabetes and its complications. PMID- 29186787 TI - Improving Pool Fencing Legislation in Queensland, Australia: Attitudes and Impact on Child Drowning Fatalities. AB - Four-sided, non-climbable pool fencing is an effective strategy for preventing children from drowning in home swimming pools. In 2009, the Queensland Government introduced legislation to improve the effectiveness of pool fencing. This study explores community attitudes towards the effectiveness of these legislative changes and examines child (<5 years) drowning deaths in pools. Data from the 2011 Queensland Computer-Assisted Telephone Interviewing (CATI) Social Survey include results from questions related to pool ownership and pool fencing legislation. Fatal child drowning cases between 1 January 2005 and 31 December 2015 were sourced from coronial data. Of the 1263 respondents, 26/100 households had a pool. A total of 58% believed tightening legislation would be effective in reducing child drowning deaths. Pool owners were more likely to doubt the effectiveness of legislation (p < 0.001) when compared to non-pool owners. Perceptions of effectiveness did not differ by presence of children under the age of five. There were 46 children who drowned in Queensland home pools (7.8/100,000 pools with children residing in the residence/annum) between 2005 and 2015. While pool owners were less likely to think that tightening the legislation would be effective, the number of children drowning in home swimming pools declined over the study period. Drowning prevention agencies have more work to do to ensure that the most vulnerable (young children in houses with swimming pools) are protected. PMID- 29186788 TI - Neurotoxic Effects of Linalool and beta-Pinene on Tribolium castaneum Herbst. AB - Effective, ethical pest control requires the use of chemicals that are highly specific, safe, and ecofriendly. Linalool and beta-pinene occur naturally as major constituents of the essential oils of many plant species distributed throughout the world, and thus meet these requirements. These monoterpenes were tested as repellents against Tribolium castaneum, using the area preference method, after four hours of exposure and the effect transcriptional of genes associated with neurotransmission. Changes in gene expression of acetylcholinesterase (Ace1), GABA-gated anion channel splice variant 3a6a (Rdl), GABA-gated ion channel (Grd), glutamate-gated chloride channel (Glucl), and histamine-gated chloride channel 2 (Hiscl2) were assessed and the interaction with proteins important for the insect using in silico methods was also studied. For linalool and beta-pinene, the repellent concentration 50 (RC50) values were 0.11 uL/cm2 and 0.03 uL/cm2, respectively. Both compounds induced overexpression of Hiscl2 gen in adult insects, and beta-pinene also promoted the overexpression of Grd and the Ace1 gene. However, beta-pinene and linalool had little potential to dock on computer-generated models for GABA-gated ion channel LCCH3, nicotinic acetylcholine receptor subunits alpha1 and alpha2, and putative octopamine/tyramine receptor proteins from T. castaneum as their respective binding affinities were marginal, and therefore the repellent action probably involved mechanisms other than direct interaction with these targets. Results indicated that beta-pinene was more potent than linalool in inducing insect repellency, and also had a greater capacity to generate changes in the expression of genes involved in neuronal transmission. PMID- 29186789 TI - Impact of Antibiotics on the Proliferation and Differentiation of Human Adipose Derived Mesenchymal Stem Cells. AB - Adipose tissue is a promising source of mesenchymal stem cells. Their potential to differentiate and regenerate other types of tissues may be affected by several factors. This may be due to in vitro cell-culture conditions, especially the supplementation with antibiotics. The aim of our study was to evaluate the effects of a penicillin-streptomycin mixture (PS), amphotericin B (AmB), a complex of AmB with copper (II) ions (AmB-Cu2+) and various combinations of these antibiotics on the proliferation and differentiation of adipose-derived stem cells in vitro. Normal human adipose-derived stem cells (ADSC, Lonza) were routinely maintained in a Dulbecco's Modified Eagle Medium (DMEM) that was either supplemented with selected antibiotics or without antibiotics. The ADSC that were used for the experiment were at the second passage. The effect of antibiotics on proliferation was analyzed using the 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyltetrazolium bromide (MTT) and sulforhodamine-B (SRB) tests. Differentiation was evaluated based on Alizarin Red staining, Oil Red O staining and determination of the expression of ADSC, osteoblast and adipocyte markers by real-time RT-qPCR. The obtained results indicate that the influence of antibiotics on adipose-derived stem cells depends on the duration of exposure and on the combination of applied compounds. We show that antibiotics alter the proliferation of cells and also promote natural osteogenesis, and adipogenesis, and that this effect is also noticeable in stimulated osteogenesis. PMID- 29186790 TI - Optimization of a Focusable and Rotatable Shear-Wave Periodic Permanent Magnet Electromagnetic Acoustic Transducers for Plates Inspection. AB - Due to the symmetry of conventional periodic-permanent-magnet electromagnetic acoustic transducers (PPM EMATs), two shear (SH) waves can be generated and propagated simultaneously in opposite directions, which makes the signal recognition and interpretation complicatedly. Thus, this work presents a new SH wave PPM EMAT design, rotating the parallel line sources to realize the wave beam focusing in a single-direction. The theoretical model of distributed line sources was deduced firstly, and the effects of some parameters, such as the inner coil width, adjacent line sources spacing and the angle between parallel line sources, on SH wave focusing and directivity were studied mainly with the help of 3D FEM. Employing the proposed PPM EMATs, some experiments are carried out to verify the reliability of FEM simulation. The results indicate that rotating the parallel line sources can strength the wave on the closing side of line sources, decreasing the inner coil width and the adjacent line sources spacing can improve the amplitude and directivity of signals excited by transducers. Compared with traditional PPM EMATs, both the capacity of unidirectional excitation and directivity of the proposed PPM EMATs are improved significantly. PMID- 29186793 TI - Connectivity and Topology Invariance in Self-Assembled and Halogen-Bonded Anionic (6,3)-Networks. AB - We report here that the halogen bond driven self-assembly of 1,3,5 trifluorotriiodobenzene with tetraethylammonium and -phosphonium bromides affords 1:1 co-crystals, wherein the mutual induced fit of the triiodobenzene derivative and the bromide anions (halogen bond donor and acceptors, respectively) elicits the potential of these two tectons to function as tritopic modules (6,3). Supramolecular anionic networks are present in the two co-crystals wherein the donor and the acceptor alternate at the vertexes of the hexagonal frames and cations are accommodated in the potential empty space encircled by the frames. The change of one component in a self-assembled multi-component co-crystal often results in a change in its supramolecular connectivity and topology. Our systems have the same supramolecular features of corresponding iodide analogues as the metric aspects seem to prevail over other aspects in controlling the self assembly process. PMID- 29186794 TI - Radioactive Cobalt(II) Removal from Aqueous Solutions Using a Reusable Nanocomposite: Kinetic, Isotherms, and Mechanistic Study. AB - A lignocellulose/montmorillonite (LMT) nanocomposite was prepared as a reusable adsorbent for cobalt(II) ions, and characterized by nitrogen (N2) adsorption/desorption isotherm, X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM), and Fourier Transform Infrared Spectroscopy (FTIR). LMT exhibited efficient adsorption of cobalt ions (Co(II)), and the adsorbed Co(II) was readily desorbed by nitric acid (HNO3). All parameters affecting the adsorption and/or desorption of Co(II), including initial Co(II) concentration, pH value, temperature, HNO3 concentration, and time, were optimized. The kinetic data analysis showed that the adsorption followed the pseudo-second-order kinetic model and fit well into the Langmuir isotherm equation. Notably, the nanocomposite can be used four times without significantly losing adsorbent capability. The Energy-Dispersive X-ray (EDX) and FTIR spectra analysis also revealed that the adsorption mechanism may be mainly a chemical adsorption dominated process. PMID- 29186792 TI - Molecular Mechanisms of GPCR Signaling: A Structural Perspective. AB - G protein-coupled receptors (GPCRs) are cell surface receptors that respond to a wide variety of stimuli, from light, odorants, hormones, and neurotransmitters to proteins and extracellular calcium. GPCRs represent the largest family of signaling proteins targeted by many clinically used drugs. Recent studies shed light on the conformational changes that accompany GPCR activation and the structural state of the receptor necessary for the interactions with the three classes of proteins that preferentially bind active GPCRs, G proteins, G protein coupled receptor kinases (GRKs), and arrestins. Importantly, structural and biophysical studies also revealed activation-related conformational changes in these three types of signal transducers. Here, we summarize what is already known and point out questions that still need to be answered. Clear understanding of the structural basis of signaling by GPCRs and their interaction partners would pave the way to designing signaling-biased proteins with scientific and therapeutic potential.

AB - Hydroboration-oxidation of 2alpha,4alpha-dimethanol-1beta,5beta-bicyclo[3.3.0]oct 6-en dibenzoate (1) gave alcohols 2 (symmetric) and 3 (unsymmetric) in ~60% yield, together with the monobenzoate diol 4a (37%), resulting from the reduction of the closer benzoate by the intermediate alkylborane. The corresponding alkene and dialdehyde gave only the triols 8 and 9 in ~1:1 ratio. By increasing the reaction time and the temperature, the isomerization of alkylboranes favours the un-symmetrical triol 9. The PDC oxidation of the alcohols gave cleanly the corresponding ketones 5 and 6 and the deprotection of the benzoate groups gave the symmetrical ketone 14, and the cyclic hemiketal 15, all in high yields. The ethylene ketals of the symmetrical ketones 11 and 13 were also obtained. The compounds 5, 6, 11, 13, 14 could be used for synthesis of new (iso)carbacyclin analogues. The structure of the compounds was established by NMR spectroscopy and confirmed by X-ray crystallography.

AB - The main focus of this paper is to investigate the multiple attribute decision making (MADM) method under intuitionistic linguistic (IL) environment, based on induced aggregation operators and analyze possibilities for its application in low carbon supplier selection. More specifically, a new aggregation operator, called intuitionistic linguistic weighted induced ordered weighted averaging (ILWIOWA), is introduced to facilitate the IL information. Some of its desired properties are explored. A further generalization of the ILWIOWA, called intuitionistic linguistic generalized weighted induced ordered weighted averaging (ILGWIOWA), operator is developed. Furthermore, by employing the proposed operators, a MADM approach based on intuitionistic linguistic information is presented. Finally, an illustrative example concerning low carbon supplier selection and comparative analyses are conducted to demonstrate the effectiveness and practicality of the proposed approach. PMID- 29186797 TI - Carbon Nanofiber Cement Sensors to Detect Strain and Damage of Concrete Specimens Under Compression. AB - Cement composites with nano-additions have been vastly studied for their functional applications, such as strain and damage sensing. The capacity of a carbon nanofiber (CNF) cement paste has already been tested. However, this study is focused on the use of CNF cement composites as sensors in regular concrete samples. Different measuring techniques and humidity conditions of CNF samples were tested to optimize the strain and damage sensing of this material. In the strain sensing tests (for compressive stresses up to 10 MPa), the response depends on the maximum stress applied. The material was more sensitive at higher loads. Furthermore, the actual load time history did not influence the electrical response, and similar curves were obtained for different test configurations. On the other hand, damage sensing tests proved the capability of CNF cement composites to measure the strain level of concrete samples, even for loads close to the material's strength. Some problems were detected in the strain transmission between sensor and concrete specimens, which will require specific calibration of each sensor one attached to the structure. PMID- 29186791 TI - How do PrPSc Prions Spread between Host Species, and within Hosts? AB - Prion diseases are sub-acute neurodegenerative diseases that affect humans and some domestic and free-ranging animals. Infectious prion agents are considered to comprise solely of abnormally folded isoforms of the cellular prion protein known as PrPSc. Pathology during prion disease is restricted to the central nervous system where it causes extensive neurodegeneration and ultimately leads to the death of the host. The first half of this review provides a thorough account of our understanding of the various ways in which PrPSc prions may spread between individuals within a population, both horizontally and vertically. Many natural prion diseases are acquired peripherally, such as by oral exposure, lesions to skin or mucous membranes, and possibly also via the nasal cavity. Following peripheral exposure, some prions accumulate to high levels within the secondary lymphoid organs as they make their journey from the site of infection to the brain, a process termed neuroinvasion. The replication of PrPSc prions within secondary lymphoid organs is important for their efficient spread to the brain. The second half of this review describes the key tissues, cells and molecules which are involved in the propagation of PrPSc prions from peripheral sites of exposure (such as the lumen of the intestine) to the brain. This section also considers how additional factors such as inflammation and aging might influence prion disease susceptibility.

PMID- 29186799 TI - Whole-Genome Re-Alignment Facilitates Development of Specific Molecular Markers for Races 1 and 4 of Xanthomonas campestris pv. campestris, the Cause of Black Rot Disease in Brassica oleracea. AB - Black rot, caused by Xanthomonas campestris pv. campestris (Xcc), is a seed borne disease of Brassicaceae. Eleven pathogenic races have been identified based on the phenotype interaction pattern of differential brassica cultivars inoculated with different strains. Race 1 and 4 are the two most frequent races found in Brassica oleracea crops. In this study, a PCR molecular diagnostic tool was developed for the identification of Xcc races 1 and 4 of this pathogen. Whole genomic sequences of races 1, 3, 4 and 9 and sequences of three other Xanthomonas pathovars/species (X. campestris pv. incanae (Xci), X. campestris pv. raphani (Xcr) and X.euvesicatoria (Xev) were aligned to identify variable regions among races. To develop specific markers for races 1 and 4, primers were developed from a region where sequences were dissimilar in other races. Sequence-characterized amplified regions (SCAR) and insertion or deletion of bases (InDel) were used to develop each specific set of primers. The specificity of the selected primers was confirmed by PCR tests using genomic DNA of seven different Xcc races, two strains of X. campestris pathovars and other species of bacteria. Bacterial samples of the races 1 and 4 isolates were collected from artificially inoculated cabbage leaves to conduct bio-PCR. Bio-PCR successfully detected the two Xcc isolates. By using our race-specific markers, a potential race 1 strain from the existing Korean Xcc collection was identified. The Xcc race 1 and 4-specific markers developed in this study are novel and can potentially be used for rapid detection of Xcc races through PCR.

AB - BACKGROUND: Despite the wealth of literature on social determinants of mental health, less is known about the intersection of these determinants. Using a nationally representative sample, this study aimed to study separate, additive, and multiplicative effects of race, gender, and SES on the risk of major depressive episode (MDE) among American adults. METHODS: National Survey of American Life (NSAL) included 3570 African Americans and 891 Whites. Race, gender, socioeconomic status (SES, household income, education, employment, and marital status) were independent variables. Twelve-month MDE was measured by the Composite International Diagnostic Interview (CIDI). A series of logistic regressions were used to analyze the data. RESULTS: In the pooled sample, race and household income, but not gender, education, employment, and marital status were associated with 12-month MDE. Gender interacted with the effects of income on MDE, suggesting that the association between household income and MDE is larger for women than men. In race by gender specific models that controlled for other SES indicators, high income was protective for White women, education was protective for African American women, and high income became a risk factor for African American men. High income did not show a risk effect for African American men in the absence of other SES indicators. CONCLUSIONS: Findings suggest that race, gender, and class interact on how SES indicators, such as education or income, become a protective or a risk factor for MDE among American Adults. When the outcome is MDE, White women benefit more from income, African American women gain from education, however, the residual effect of high income (above and beyond education, employment, and marital status) may become a risk factor for African American men. PMID- 29186801 TI - Epigenetic Basis of Cellular Senescence and Its Implications in Aging. AB - Cellular senescence is a tumor suppressive response that has become recognized as a major contributor of tissue aging. Senescent cells undergo a stable proliferative arrest that protects against neoplastic transformation, but acquire a secretory phenotype that has long-term deleterious effects. Studies are still unraveling the effector mechanisms that underlie these senescence responses with the goal to identify therapeutic interventions. Such effector mechanisms have been linked to the dramatic remodeling in the epigenetic and chromatin landscape that accompany cellular senescence. We discuss these senescence-associated epigenetic changes and their impact on the senescence phenotypes, notably the proliferative arrest and senescence associated secretory phenotype (SASP). We also explore possible epigenetic targets to suppress the deleterious effects of senescent cells that contribute towards aging. PMID- 29186802 TI - Bronchitis and Its Associated Risk Factors in First Nations Children. AB - Respiratory diseases, such as bronchitis and pneumonia, are common in First Nations children in Canada. The objectives are to determine prevalence and associated risk factors of bronchitis in children 6-17 years old residing in two reserve communities. The cross-sectional study was conducted in 2013 and children from two First Nations reserve communities participated. The outcome was ever presence/absence of bronchitis. Logistic regression analysis was conducted to examine the relationship between bronchitis and the individual and environmental factors. A total of 351 First Nations children participated in the study. The prevalence of bronchitis was 17.9%. While 86.6% had at least one parent who smoked, smoking inside home was 43.9%. Signs of mold and mildew in homes were high. Prevalence of houses with any damage caused by dampness was 42.2%, with 44.2% of homes showing signs of mold or mildew. Significant predictors of increased risk of bronchitis were: being obese; having respiratory allergies; exposed to parental cigarette smoking; and signs of mold and mildew in the home. There are several modifiable risk factors that should be considered when examining preventive interventions for bronchitis including obesity, smoking exposure, and home mold or dampness. PMID- 29186803 TI - Effects of Different Types of Front-of-Pack Labelling Information on the Healthiness of Food Purchases-A Randomised Controlled Trial. AB - BACKGROUND: Front-of-pack nutrition labelling may support healthier packaged food purchases. Australia has adopted a novel Health Star Rating (HSR) system, but the legitimacy of this choice is unknown. OBJECTIVE: To define the effects of different formats of front-of-pack labelling on the healthiness of food purchases and consumer perceptions. DESIGN: Individuals were assigned at random to access one of four different formats of nutrition labelling-HSR, multiple traffic light labels (MTL), daily intake guides (DIG), recommendations/warnings (WARN)-or control (the nutrition information panel, NIP). Participants accessed nutrition information by using a smartphone application to scan the bar-codes of packaged foods, while shopping. The primary outcome was healthiness defined by the mean transformed nutrient profile score of packaged foods that were purchased over four weeks. RESULTS: The 1578 participants, mean age 38 years, 84% female recorded purchases of 148,727 evaluable food items. The mean healthiness of the purchases in the HSR group was non-inferior to MTL, DIG, or WARN (all p < 0.001 at 2% non-inferiority margin). When compared to the NIP control, there was no difference in the mean healthiness of purchases for HSR, MTL, or DIG (all p > 0.07), but WARN resulted in healthier packaged food purchases (mean difference 0.87; 95% confidence interval 0.03 to 1.72; p = 0.04). HSR was perceived by participants as more useful than DIG, and easier to understand than MTL or DIG (all p < 0.05). Participants also reported the HSR to be easier to understand, and the HSR and MTL to be more useful, than NIP (all p < 0.03). CONCLUSIONS: These real-world data align with experimental findings and provide support for the policy choice of HSR. Recommendation/warning labels warrant further exploration, as they may be a stronger driver of healthy food purchases. PMID- 29186804 TI - Neonatal Nutrition Predicts Energy Balance in Young Adults Born Preterm at Very Low Birth Weight. AB - Epidemiological studies and animal models suggest that early postnatal nutrition and growth can influence adult health. However, few human studies have objective recordings of early nutrient intake. We studied whether nutrient intake and growth during the first 9 weeks after preterm birth with very low birth weight (VLBW, <1500 g) predict total energy intake, resting energy expenditure (REE), physical activity and food preferences in young adulthood. We collected daily nutritional intakes and weights during the initial hospital stay from hospital records for 127 unimpaired VLBW participants. At an average age 22.5 years, they completed a three-day food record and a physical activity questionnaire and underwent measurements of body composition (dual X-ray absorptiometry; n = 115 with adequate data) and REE (n = 92 with adequate data). We used linear regression and path analysis to investigate associations between neonatal nutrient intake and adult outcomes. Higher energy, protein and fat intakes during the first three weeks of life predicted lower relative (=per unit lean body mass) energy intake and relative REE in adulthood, independent of other pre- and neonatal factors. In path analysis, total effects of early nutrition and growth on relative energy intake were mostly explained by direct effects of early life nutrition. A path mediated by early growth reached statistical significance only for protein intake. There were no associations of neonatal intakes with physical activity or food preferences in adulthood. As a conclusion, higher intake of energy and nutrients during first three weeks of life of VLBW infants predicts energy balance after 20 years. This association is partly mediated through postnatal growth. PMID- 29186805 TI - Is Antimicrobial Photodynamic Therapy Effective as an Adjunct to Scaling and Root Planing in Patients with Chronic Periodontitis? A Systematic Review. AB - The aim of this systematic review was to investigate whether antimicrobial photodynamic therapy (aPDT) as either a primary mode of treatment or an adjunct to non-surgical treatment was more effective than scaling and root planing (SRP) alone in treating chronic periodontitis in terms of clinical attachment level (CAL) gain and probing depth (PD) reduction. The focused question was developed using the Patient, Intervention, Comparison, and Outcome (PICO) format, and two authors independently searched the Medline, EMBASE, Cochrane Library, Web of Science, Google Scholar, and Scopus databases for relevant studies from January 2008 to December 2016. Twenty studies included in this systematic review were randomized clinical trials (RCTs) or quasi-RCTs of aPDT compared to placebo, no intervention, or non-surgical treatment in an adult population. Basic study characteristics, photosensitizing agents and wavelengths used in aPDT, frequency of aPDT application, effect of aPDT on clinical parameters, antimicrobial effect of aPDT in chronic periodontitis, effect of immunological parameters following aPDT and patient-based outcome measures were collected from the studies. Although there was a wide range of heterogeneity in the included studied, they all indicated that aPDT has the potential to be an effective adjunct in the treatment of chronic periodontitis. Long-term, multicenter studies with larger sample sizes are needed before aPDT can be recommended as an effective treatment modality. PMID- 29186806 TI - The Silencing of Carotenoid beta-Hydroxylases by RNA Interference in Different Maize Genetic Backgrounds Increases the beta-Carotene Content of the Endosperm. AB - Maize (Zea mays L.) is a staple food in many parts of Africa, but the endosperm generally contains low levels of the pro-vitamin A carotenoid beta-carotene, leading to vitamin A deficiency disease in populations relying on cereal-based diets. However, maize endosperm does accumulate high levels of other carotenoids, including zeaxanthin, which is derived from beta-carotene via two hydroxylation reactions. Blocking these reactions could therefore improve the endosperm beta carotene content. Accordingly, we used RNA interference (RNAi) to silence the endogenous ZmBCH1 and ZmBCH2 genes, which encode two non-heme di-iron carotenoid beta-hydroxylases. The genes were silenced in a range of maize genetic backgrounds by introgressing the RNAi cassette, allowing us to determine the impact of ZmBCH1/ZmBCH2 silencing in diverse hybrids. The beta-carotene content of the endosperm increased substantially in all hybrids in which ZmBCH2 was silenced, regardless of whether or not ZmBCH1 was silenced simultaneously. However, the beta-carotene content did not change significantly in C17 hybrids (M7 * C17 and M13 * C17) compared to C17 alone, because ZmBCH2 is already expressed at negligible levels in the C17 parent. Our data indicate that ZmBCH2 is primarily responsible for the conversion of beta-carotene to zeaxanthin in maize endosperm. PMID- 29186807 TI - The POZ/BTB and AT-Hook Containing Zinc Finger 1 (PATZ1) Transcription Regulator: Physiological Functions and Disease Involvement. AB - PATZ1 is a zinc finger protein, belonging to the POZ domain Kruppel-like zinc finger (POK) family of architectural transcription factors, first discovered in 2000 by three independent groups. Since that time accumulating evidences have shown its involvement in a variety of biological processes (i.e., embryogenesis, stemness, apoptosis, senescence, proliferation, T-lymphocyte differentiation) and human diseases. Here we summarize these studies with a focus on the PATZ1 emerging and controversial role in cancer, where it acts as either a tumor suppressor or an oncogene. Finally, we give some insight on clinical perspectives using PATZ1 as a prognostic marker and therapeutic target. PMID- 29186808 TI - Controlling the Molecular Weight of Lignosulfonates by an Alkaline Oxidative Treatment at Moderate Temperatures and Atmospheric Pressure: A Size-Exclusion and Reverse-Phase Chromatography Study. AB - The molecular weights of lignosulfonates (LSs) are modified by a rather simple process involving an alkaline oxidative treatment at moderate temperatures (70-90 degrees C) and atmospheric pressure. Starting from LSs with an average molecular weight of 90,000 Da, and using such a treatment, one can prepare controlled molecular weight LSs in the range of 30,000 to 3500 Da based on the average mass molecular weight. The LS depolymerisation was monitored via reverse-phase and size-exclusion chromatography. It has been shown that the combination of O2, H2O2 and Cu as a catalyst in alkaline conditions at 80 degrees C induces a high LS depolymerisation. The depolymerisation was systemically accompanied by a vanillin production, the yields of which reached 1.4 wt % (weight percentage on LS raw basis) in such conditions. Also, the average molecular weight and vanillin concentration were correlated and depended linearly on the temperature and reaction duration. PMID- 29186809 TI - Aptamer Bioinformatics. AB - Aptamers are short nucleic acid sequences capable of specific, high-affinity molecular binding. They are isolated via SELEX (Systematic Evolution of Ligands by Exponential Enrichment), an evolutionary process that involves iterative rounds of selection and amplification before sequencing and aptamer characterization. As aptamers are genetic in nature, bioinformatic approaches have been used to improve both aptamers and their selection. This review will discuss the advancements made in several enclaves of aptamer bioinformatics, including simulation of aptamer selection, fragment-based aptamer design, patterning of libraries, identification of lead aptamers from high-throughput sequencing (HTS) data and in silico aptamer optimization. PMID- 29186810 TI - Dynamic Mechanical Properties and Microstructure of Graphene Oxide Nanosheets Reinforced Cement Composites. AB - This paper presents an experimental investigation on the effect of uniformly dispersed graphene oxide (GO) nanosheets on dynamic mechanical properties of cement based composites prepared with recycled fine aggregate (RFA). Three different amounts of GO, 0.05%, 0.10%, and 0.20% in mass of cement, were used in the experiments. The visual inspections of GO nanosheets were also carried out after ultrasonication by transmission electron microscope (TEM) atomic force microscope (AFM), and Raman to characterize the dispersion effect of graphite oxide. Dynamic mechanical analyzer test showed that the maximum increased amount of loss factor and storage modulus, energy absorption was 125%, 53%, and 200% when compared to the control sample, respectively. The flexural and compressive strengths of GO-mortar increased up to 22% to 41.3% and 16.2% to 16.4% with 0.20 wt % GO at 14 and 28 days, respectively. However the workability decreased by 7.5% to 18.8% with 0.05% and 0.2% GO addition. Microstructural analysis with environmental scanning electron microscopy (ESEM)/backscattered mode (BSEM) showed that the GO-cement composites had a much denser structure and better crystallized hydration products, meanwhile mercury intrusion porosimetry (MIP) testing and image analysis demonstrated that the incorporation of GO in the composites can help in refining capillary pore structure and reducing the air voids content. PMID- 29186811 TI - Ascorbic Acid Attenuates Senescence of Human Osteoarthritic Osteoblasts. AB - The accumulation of senescent cells is implicated in the pathology of several age related diseases. While the clearance of senescent cells has been suggested as a therapeutic target for patients with osteoarthritis (OA), cellular senescence of bone-resident osteoblasts (OB) remains poorly explored. Since oxidative stress is a well-known inducer of cellular senescence, we here investigated the effect of antioxidant supplementation on the isolation efficiency, expansion, differentiation potential, and transcriptomic profile of OB from osteoarthritic subchondral bone. Bone chips were harvested from sclerotic and non-sclerotic regions of the subchondral bone of human OA joints. The application of 0.1 mM ascorbic acid-2-phosphate (AA) significantly increased the number of outgrowing cells and their proliferation capacity. This enhanced proliferative capacity showed a negative correlation with the amount of senescent cells and was accompanied by decreased expression of reactive oxygen species (ROS) in cultured OB. Expanded cells continued to express differentiated OB markers independently of AA supplementation and demonstrated no changes in their capacity to osteogenically differentiate. Transcriptomic analyses revealed that apoptotic, cell cycle-proliferation, and catabolic pathways were the main pathways affected in the presence of AA during OB expansion. Supplementation with AA can thus help to expand subchondral bone OB in vitro while maintaining their special cellular characteristics. The clearance of such senescent OB could be envisioned as a potential therapeutic target for the treatment of OA. PMID- 29186812 TI - Biotechnological Applications of Microbial (Per)chlorate Reduction. AB - While the microbial degradation of a chloroxyanion-based herbicide was first observed nearly ninety years ago, only recently have researchers elucidated the underlying mechanisms of perchlorate and chlorate [collectively, (per)chlorate] respiration. Although the obvious application of these metabolisms lies in the bioremediation and attenuation of (per)chlorate in contaminated environments, a diversity of alternative and innovative biotechnological applications has been proposed based on the unique metabolic abilities of dissimilatory (per)chlorate reducing bacteria (DPRB). This is fueled in part by the unique ability of these organisms to generate molecular oxygen as a transient intermediate of the central pathway of (per)chlorate respiration. This ability, along with other novel aspects of the metabolism, have resulted in a wide and disparate range of potential biotechnological applications being proposed, including enzymatic perchlorate detection; gas gangrene therapy; enhanced xenobiotic bioremediation; oil reservoir bio-souring control; chemostat hygiene control; aeration enhancement in industrial bioreactors; and, biogenic oxygen production for planetary exploration. While previous reviews focus on the fundamental science of microbial (per)chlorate reduction (for example see Youngblut et al., 2016), here, we provide an overview of the emerging biotechnological applications of (per)chlorate respiration and the underlying organisms and enzymes to environmental and biotechnological industries. PMID- 29186813 TI - Chemical Profiling and Bioactivity of Body Wall Lipids from Strongylocentrotus droebachiensis. AB - The lipids from gonads and polyhydroxynaphthoquinone pigments from body walls of sea urchins are intensively studied. However, little is known about the body wall (BW) lipids. Ethanol extract (55 degrees C) contained about equal amounts of saturated (SaFA) and monounsaturated fatty acids (MUFA) representing 60% of total fatty acids, with myristic, palmitic and eicosenoic acids as major SaFAs and MUFAs, respectively. Non-methylene-interrupted dienes (13%) were composed of eicosadienoic and docosadienoic acids. Long-chain polyunsaturated fatty acids (LC PUFA) included two main components, n6 arachidonic and n3 eicosapentaenoic acids, even with equal concentrations (15 MUg/mg) and a balanced n6/n3 PUFA ratio (0.86). The UPLC-ELSD analysis showed that a great majority of the lipids (80%) in the ethanolic extract were phosphatidylcholine (60 MUg/mg) and phosphatidylethanolamine (40 MUg/mg), while the proportion of neutral lipids remained lower than 20%. In addition, alkoxyglycerol derivatives-chimyl, selachyl, and batyl alcohols-were quantified. We have assumed that the mechanism of action of body wall lipids in the present study is via the inhibition of MAPK p38, COX-1, and COX-2. Our findings open the prospective to utilize this lipid fraction as a source for the development of drugs with anti-inflammatory activity. PMID- 29186814 TI - Alternative Splicing of L-type CaV1.2 Calcium Channels: Implications in Cardiovascular Diseases. AB - L-type Cav1.2 calcium channels are the major pathway for Ca2+ influx to initiate the contraction of smooth and cardiac muscles. Alteration of Cav1.2 channel function has been implicated in multiple cardiovascular diseases, such as hypertension and cardiac hypertrophy. Alternative splicing is a post transcriptional mechanism that expands Cav1.2 channel structures to modify function, pharmacological and biophysical property such as calcium/voltage dependent inactivation (C/VDI), or to influence its post-translational modulation by interacting proteins such as Galectin-1. Alternative splicing has generated functionally diverse Cav1.2 isoforms that can be developmentally regulated in the heart, or under pathophysiological conditions such as in heart failure. More importantly, alternative splicing of certain exons of Cav1.2 has been reported to be regulated by splicing factors such as RNA-binding Fox-1 homolog 1/2 (Rbfox 1/2), polypyrimidine tract-binding protein (PTBP1) and RNA-binding motif protein 20 (RBM20). Understanding how Cav1.2 channel function is remodelled in disease will provide better information to guide the development of more targeted approaches to discover therapeutic agents for cardiovascular diseases. PMID- 29186815 TI - Characterization of the Transcriptome and Gene Expression of Tetraploid Black Locust Cuttings in Response to Etiolation. AB - Etiolation (a process of growing plants in partial or complete absence of light) promotes adventitious root formation in tetraploid black locust (Robinia pseudoacacia L.) cuttings. We investigated the mechanism underlying how etiolation treatment promotes adventitious root formation in tetraploid black locust and assessed global transcriptional changes after etiolation treatment. Solexa paired-end sequencing of complementary DNAs (cDNAs) from control (non etiolated, NE) and etiolated (E) samples resulted in 107,564 unigenes. In total, 52,590 transcripts were annotated and 474 transcripts (211 upregulated and 263 downregulated) potentially involved in etiolation were differentially regulated. These genes were associated with hormone metabolism and response, photosynthesis, signaling pathways, and starch and sucrose metabolism. In addition, we also found significant differences of phytohormone contents, activity of following enzymes i.e., peroxidase, polyphenol oxidase and indole acetic acid oxidase between NE and E tissues during some cottage periods. The genes responsive to etiolation stimulus identified in this study will provide the base for further understanding how etiolation triggers adventitious roots formation in tetraploid black locus. PMID- 29186816 TI - The Geography of the Alzheimer's Disease Mortality in Spain: Should We Focus on Industrial Pollutants Prevention? AB - Alzheimer's disease (AD) has a high worldwide prevalence but little is known about its aetiology and risk factors. Recent research suggests environmental factors might increase AD risk. We aim to describe the association between AD mortality and the presence of highly polluting industry in small areas in Spain between 1999 and 2010. We calculated AD age-adjusted Standardized Mortality Ratio (SMR), stratified by sex, grouped by industrial pollution density, compared for each small area of Spain. In the small areas with the highest mortality, the SMR among women was at least 25% greater than the national average (18% in men). The distribution of AD mortality was generally similar to that of high industrial pollution (higher mortality in the north, the Mediterranean coast and in some southern areas). The risk of AD mortality among women was 140% higher (123% among men) in areas with the highest industrial density in comparison to areas without polluting industries. This study has identified a geographical pattern of small areas with higher AD mortality risk and an ecological positive association with the density of highly polluting industry. Further research is needed on the potential impact of this type of industry pollution on AD aetiology and mortality. PMID- 29186817 TI - Toxicity Assessment of Carbon Nanomaterials in Zebrafish during Development. AB - Carbon nanomaterials (CNMs) are increasingly employed in nanomedicine as carriers for intracellular transport of drugs, imaging probes, and therapeutics agents, thanks to their unique optical and physicochemical properties. However, a better understanding about the effects of CNMs on a vertebrate model at the whole animal level is required. In this study, we compare the toxicity of oxidized carbon nano onions (oxi-CNOs), oxidized carbon nano-horns (oxi-CNHs) and graphene oxide (GO) in zebrafish (Danio rerio). We evaluate the possible effects of these nanomaterials on zebrafish development by assessing different end-points and exposure periods. PMID- 29186819 TI - Photoactive Gel for Assisted Cleaning during Olive Mill Wastewater Membrane Microfiltration. AB - A photoactive gel has been fabricated on the surface of polyethylene membranes for enhancing the fouling resistance during olive mill wastewater treatment. Light and pH responsive materials have been introduced in the membrane surface through the build up of a layer-by-layer pattern, which is formed by photocatalytic nanoparticles and ionic polyelectrolytes. The best working conditions to contrast foulants adsorption have been explored and identified. Repulsive interfacial forces and assisted transfer of foulants to catalytic sites have been envisaged as crucial factors for contrasting the decline of the flux during microfiltration. Tests in submerged configuration have been implemented for six continuous hours under irradiation at two different pH conditions. As a result, a worthy efficiency of the photoactive gel has been reached when suitable chemical microenvironments have been generated along the shell side of the membranes. No additional chemical reagents or expensive back-flushing procedures have been necessary to further clean the membranes; rather, fast and reversible pH switches have been enough to remove residues, thereby preserving the integrity of the layer-by-layer (LBL) complex onto the membrane surface. PMID- 29186818 TI - Multipurpose HTS Coagulation Analysis: Assay Development and Assessment of Coagulopathic Snake Venoms. AB - Coagulation assays currently employed are often low throughput, require specialized equipment and/or require large blood/plasma samples. This study describes the development, optimization and early application of a generic low volume and high-throughput screening (HTS) assay for coagulation activity. The assay is a time-course spectrophotometric measurement which kinetically measures the clotting profile of bovine or human plasma incubated with Ca2+ and a test compound. The HTS assay can be a valuable new tool for coagulation diagnostics in hospitals, for research in coagulation disorders, for drug discovery and for venom research. A major effect following envenomation by many venomous snakes is perturbation of blood coagulation caused by haemotoxic compounds present in the venom. These compounds, such as anticoagulants, are potential leads in drug discovery for cardiovascular diseases. The assay was implemented in an integrated analytical approach consisting of reversed-phase liquid chromatography (LC) for separation of crude venom components in combination with parallel post-column coagulation screening and mass spectrometry (MS). The approach was applied for the rapid assessment and identification of profiles of haemotoxic compounds in snake venoms. Procoagulant and anticoagulant activities were correlated with accurate masses from the parallel MS measurements, facilitating the detection of peptides showing strong anticoagulant activity. PMID- 29186820 TI - Integrative Bioinformatic Analysis of Transcriptomic Data Identifies Conserved Molecular Pathways Underlying Ionizing Radiation-Induced Bystander Effects (RIBE). AB - Ionizing radiation-induced bystander effects (RIBE) encompass a number of effects with potential for a plethora of damages in adjacent non-irradiated tissue. The cascade of molecular events is initiated in response to the exposure to ionizing radiation (IR), something that may occur during diagnostic or therapeutic medical applications. In order to better investigate these complex response mechanisms, we employed a unified framework integrating statistical microarray analysis, signal normalization, and translational bioinformatics functional analysis techniques. This approach was applied to several microarray datasets from Gene Expression Omnibus (GEO) related to RIBE. The analysis produced lists of differentially expressed genes, contrasting bystander and irradiated samples versus sham-irradiated controls. Furthermore, comparative molecular analysis through BioInfoMiner, which integrates advanced statistical enrichment and prioritization methodologies, revealed discrete biological processes, at the cellular level. For example, the negative regulation of growth, cellular response to Zn2+-Cd2+, and Wnt and NIK/NF-kappaB signaling, thus refining the description of the phenotypic landscape of RIBE. Our results provide a more solid understanding of RIBE cell-specific response patterns, especially in the case of high-LET radiations, like alpha-particles and carbon-ions. PMID- 29186821 TI - Bacterial Endophyte Colonization and Distribution within Plants. AB - The plant endosphere contains a diverse group of microbial communities. There is general consensus that these microbial communities make significant contributions to plant health. Both recently adopted genomic approaches and classical microbiology techniques continue to develop the science of plant-microbe interactions. Endophytes are microbial symbionts residing within the plant for the majority of their life cycle without any detrimental impact to the host plant. The use of these natural symbionts offers an opportunity to maximize crop productivity while reducing the environmental impacts of agriculture. Endophytes promote plant growth through nitrogen fixation, phytohormone production, nutrient acquisition, and by conferring tolerance to abiotic and biotic stresses. Colonization by endophytes is crucial for providing these benefits to the host plant. Endophytic colonization refers to the entry, growth and multiplication of endophyte populations within the host plant. Lately, plant microbiome research has gained considerable attention but the mechanism allowing plants to recruit endophytes is largely unknown. This review summarizes currently available knowledge about endophytic colonization by bacteria in various plant species, and specifically discusses the colonization of maize plants by Populus endophytes. PMID- 29186823 TI - The Subcellular Distribution of Alpha-Tocopherol in the Adult Primate Brain and Its Relationship with Membrane Arachidonic Acid and Its Oxidation Products. AB - The relationship between alpha-tocopherol, a known antioxidant, and polyunsaturated fatty acid (PUFA) oxidation, has not been directly investigated in the primate brain. This study characterized the membrane distribution of alpha tocopherol in brain regions and investigated the association between membrane alpha-tocopherol and PUFA content, as well as brain PUFA oxidation products. Nuclear, myelin, mitochondrial, and neuronal membranes were isolated using a density gradient from the prefrontal cortex (PFC), cerebellum (CER), striatum (ST), and hippocampus (HC) of adult rhesus monkeys (n = 9), fed a stock diet containing vitamin E (alpha-, gamma-tocopherol intake: ~0.7 umol/kg body weight/day, ~5 umol/kg body weight/day, respectively). alpha-tocopherol, PUFAs, and PUFA oxidation products were measured using high performance liquid chromatography (HPLC), gas chromatography (GC) and liquid chromatography-gas chromatography/mass spectrometry (LC-GC/MS) respectively. alpha-Tocopherol (ng/mg protein) was highest in nuclear membranes (p < 0.05) for all regions except HC. In PFC and ST, arachidonic acid (AA, ug/mg protein) had a similar membrane distribution to alpha-tocopherol. Total alpha-tocopherol concentrations were inversely associated with AA oxidation products (isoprostanes) (p < 0.05), but not docosahexaenoic acid oxidation products (neuroprostanes). This study reports novel data on alpha-tocopherol accumulation in primate brain regions and membranes and provides evidence that alpha-tocopherol and AA are similarly distributed in PFC and ST membranes, which may reflect a protective effect of alpha-tocopherol against AA oxidation.

AB - Herpesviral capsid assembly is initiated in the nucleoplasm of the infected cell. Size constraints require that newly formed viral nucleocapsids leave the nucleus by an evolutionarily conserved vescular transport mechanism called nuclear egress. Mature capsids released from the nucleoplasm are engaged in a membrane mediated budding process, composed of primary envelopment at the inner nuclear membrane and de-envelopment at the outer nuclear membrane. Once in the cytoplasm, the capsids receive their secondary envelope for maturation into infectious virions. Two viral proteins conserved throughout the herpesvirus family, the integral membrane protein pUL34 and the phosphoprotein pUL31, form the nuclear egress complex required for capsid transport from the infected nucleus to the cytoplasm. Formation of the nuclear egress complex results in budding of membrane vesicles revealing its function as minimal virus-encoded membrane budding and scission machinery. The recent structural analysis unraveled details of the heterodimeric nuclear egress complex and the hexagonal coat it forms at the inside of budding vesicles to drive primary envelopment. With this review, I would like to present the capsid-escort-model where pUL31 associates with capsids in nucleoplasmic replication compartments for escort to sites of primary envelopment thereby coupling capsid maturation and nuclear egress. PMID- 29186824 TI - Investigating Exchange Bias and Coercivity in Fe3O4-gamma-Fe2O3 Core-Shell Nanoparticles of Fixed Core Diameter and Variable Shell Thicknesses. AB - We have carried out extensive measurements on novel Fe3O4-gamma-Fe2O3 core-shell nanoparticles of nearly similar core diameter (8 nm) and of various shell thicknesses of 1 nm (sample S1), 3 nm (sample S2), and 5 nm (sample S3). The structure and morphology of the samples were studied using X-ray diffraction (XRD), transmission electron microscopy (TEM), and selected area electron diffraction (SAED). The direct current (DC) magnetic measurements were carried out using a superconducting quantum interference device (SQUID). Exchange bias and coercivity were investigated at several temperatures where the applied field was varied between 3 and -3 T. Several key results are obtained, such as: (a) the complete absence of exchange bias effect in sample S3; (b) the occurrence of nonconventional exchange bias effect in samples S2 and S1; (c) the sign-change of exchange bias field in sample S2; (d) the monotonic increase of coercivity with temperature above 100 K in all samples; (e) the existence of a critical temperature (100 K) at which the coercivity is minimum; (f) the surprising suppression of coercivity upon field-cooling; and (g) the observation of coercivity at all temperatures, even at 300 K. The results are discussed and attributed to the existence of spin glass clusters at the core-shell interface. PMID- 29186825 TI - Experimental Comparison of Photothermal Conversion Efficiency of Gold Nanotriangle and Nanorod in Laser Induced Thermal Therapy. AB - An experimental comparison of the photothermal conversion efficiency (PCE) for gold nanotriangles (GNTs) and nanorods (GNRs) was carried out in the present work. The discrete dipole approximation method was applied to identify the spectral characteristic of GNTs and GNRs with different aspect ratios. On this basis, the PCE of GNTs and GNRs in photothermal therapy were compared theoretically. Afterwards, an in vitro experiment was adopted to investigate the thermal effect of porcine muscle induced by laser irradiation, with and without injected GNTs and GNRs. The influences of laser total power, nanoparticle concentration, and nanoparticle type were investigated. It was found that for the commonly-used wavelengths for photothermal therapy, the PCE of GNTs is higher than that of the GNRs. Furthermore, for GNRs loaded in tissue in vitro, high laser power and high concentration of nanoparticles leads to the degeneration and even carbonization of tissue. However, for the GNTs with the same situation (laser power, nanoparticle volume concentration, and heating time), it could lead to the tissue's evaporation instead of carbonization.

AB - Unlike conventional physical and chemical methods, the biogenic synthesis of gold nanoparticles (GNPs) is considered a green and non-toxic approach to produce biocompatible GNPs that can be utilized in various biomedical applications. This can be achieved by using plant-derived phytochemicals to reduce gold salt into GNPs. Several green synthesized GNPs have been shown to have antibacterial effects, which can be applied in wound dressings to prevent wound infections. Therefore, the aim of this study is to synthesize biogenic GNPs from the South African Galenia africana and Hypoxis hemerocallidea plants extracts and evaluate their antibacterial activity, using the Alamar blue assay, against bacterial strains that are known to cause wound infections. Additionally, we investigated the toxicity of the biogenic GNPs to non-cancerous human fibroblast cells (KMST 6) using 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay. In this paper, spherical GNPs, with particle sizes ranging from 9 to 27 nm, were synthesized and fully characterized. The GNPs from H. hemerocallidea exhibited antibacterial activity against all the tested bacterial strains, whereas GNPs produced from G. africana only exhibited antibacterial activity against Pseudomonas aeruginosa. The GNPs did not show any significant toxicity towards KMST-6 cells, which may suggest that these nanoparticles can be safely applied in wound dressings. PMID- 29186827 TI - Eukaryotic Elongation Factor 2 Kinase (eEF2K) in Cancer. AB - Eukaryotic elongation factor 2 kinase (eEF2K) is a highly unusual protein kinase that negatively regulates the elongation step of protein synthesis. This step uses the vast majority of the large amount of energy and amino acids required for protein synthesis. eEF2K activity is controlled by an array of regulatory inputs, including inhibition by signalling through mammalian target of rapamycin complex 1 (mTORC1). eEF2K is activated under conditions of stress, such as energy depletion or nutrient deprivation, which can arise in poorly-vascularised tumours. In many such stress conditions, eEF2K exerts cytoprotective effects. A growing body of data indicates eEF2K aids the growth of solid tumours in vivo. Since eEF2K is not essential (in mice) under 'normal' conditions, eEF2K may be a useful target in the treatment of solid tumours. However, some reports suggest that eEF2K may actually impair tumorigenesis in some situations. Such a dual role of eEF2K in cancer would be analogous to the situation for other pathways involved in cell metabolism, such as autophagy and mTORC1. Further studies are needed to define the role of eEF2K in different tumour types and at differing stages in tumorigenesis, and to assess its utility as a therapeutic target in oncology. PMID- 29186828 TI - Drug-Target Interaction Prediction through Label Propagation with Linear Neighborhood Information. AB - Interactions between drugs and target proteins provide important information for the drug discovery. Currently, experiments identified only a small number of drug target interactions. Therefore, the development of computational methods for drug target interaction prediction is an urgent task of theoretical interest and practical significance. In this paper, we propose a label propagation method with linear neighborhood information (LPLNI) for predicting unobserved drug-target interactions. Firstly, we calculate drug-drug linear neighborhood similarity in the feature spaces, by considering how to reconstruct data points from neighbors. Then, we take similarities as the manifold of drugs, and assume the manifold unchanged in the interaction space. At last, we predict unobserved interactions between known drugs and targets by using drug-drug linear neighborhood similarity and known drug-target interactions. The experiments show that LPLNI can utilize only known drug-target interactions to make high-accuracy predictions on four benchmark datasets. Furthermore, we consider incorporating chemical structures into LPLNI models. Experimental results demonstrate that the model with integrated information (LPLNI-II) can produce improved performances, better than other state-of-the-art methods. The known drug-target interactions are an important information source for computational predictions. The usefulness of the proposed method is demonstrated by cross validation and the case study. PMID- 29186829 TI - Inhibition by Commercial Aminoglycosides of Human Connexin Hemichannels Expressed in Bacteria. AB - In addition to gap junctional channels that mediate cell-to-cell communication, connexins form hemichannels that are present at the plasma membrane. Since hemichannels are permeable to small hydrophilic compounds, including metabolites and signaling molecules, their abnormal opening can cause or contribute to cell damage in disorders such as cardiac infarct, stroke, deafness, skin diseases, and cataracts. Therefore, hemichannels are potential pharmacological targets. A few aminoglycosides, well-known broad-spectrum antibiotics, have been shown to inhibit hemichannels. Here, we tested several commercially available aminoglycosides for inhibition of human connexin hemichannels using a cell-based bacterial growth complementation assay that we developed recently. We found that kanamycin A, kanamycin B, geneticin, neomycin, and paromomycin are effective inhibitors of hemichannels formed by connexins 26, 43, and 46 (Cx26, Cx43, and Cx46). Because of the >70 years of clinical experience with aminoglycosides and the fact that several of the aminoglycosides tested here have been used in humans, they are promising starting points for the development of effective connexin hemichannel inhibitors. PMID- 29186831 TI - Integrated Management of Residential Indoor Air Quality: A Call for Stakeholders in a Changing Climate. AB - A paradigm change in the management of environmental health issues has been observed in recent years: instead of managing specific risks individually, a holistic vision of environmental problems would assure sustainable solutions. However, concrete actions that could help translate these recommendations into interventions are lacking. This review presents the relevance of using an integrated indoor air quality management approach to ensure occupant health and comfort. At the nexus of three basic concepts (reducing contaminants at the source, improving ventilation, and, when relevant, purifying the indoor air), this approach can help maintain and improve indoor air quality and limit exposure to several contaminants. Its application is particularly relevant in a climate change context since the evolving outdoor conditions have to be taken into account during building construction and renovation. The measures presented through this approach target public health players, building managers, owners, occupants, and professionals involved in building design, construction, renovation, and maintenance. The findings of this review will help the various stakeholders initiate a strategic reflection on the importance of indoor air quality and climate change issues for existing and future buildings. Several new avenues and recommendations are presented to set the path for future research activities. PMID- 29186830 TI - The Genetic Basis of Psoriasis. AB - Psoriasis is widely regarded as a multifactorial condition which is caused by the interaction between inherited susceptibility alleles and environmental triggers. In the last decade, technological advances have enabled substantial progress in the understanding of disease genetics. Genome-wide association studies have identified more than 60 disease susceptibility regions, highlighting the pathogenic involvement of genes related to Th17 cell activation. This pathway has now been targeted by a new generation of biologics that have shown great efficacy in clinical trials. At the same time, the study of rare variants of psoriasis has identified interleukin (IL)-36 cytokines as important amplifiers of Th17 signaling and promising targets for therapeutic intervention. Here, we review these exciting discoveries, which highlight the translational potential of genetic studies. PMID- 29186832 TI - The Prevalence of Vitamin A Deficiency in Chinese Children: A Systematic Review and Bayesian Meta-Analysis. AB - Vitamin A deficiency (VAD), a leading cause of preventable childhood blindness, has been recognized as an important public health problem in many developing countries. In this study, we conducted a systematic review to identify all population-based studies of VAD and marginal VAD (MVAD) in Chinese children published from 1990 onwards. Hierarchical Bayesian meta-regressions were performed to examine the effects of age, sex, setting and year on the prevalence of VAD and MVAD, separately. The estimated prevalence was applied to the Chinese pediatric population in the year 2015 to generate prevalence estimates of VAD and MVAD for defined age groups, with 95% credible intervals (CrIs). Fifty-four studies met the inclusion criteria. The prevalence of VAD and MVAD both decreased with increasing age, and rural children had a higher prevalence of VAD and MVAD than urban children. In 2015, the prevalence of VAD was 5.16% (95% CrI: 1.95 12.64) and that of MVAD was 24.29% (95% CrI: 12.69-41.27) in Chinese children aged 12 years and under. VAD remains a public health problem in China. Efforts to reduce VAD in younger children are needed, especially for those in rural areas. PMID- 29186833 TI - Terpenoids and Phenylpropanoids in Ligularia duciformis, L. kongkalingensis, L. nelumbifolia, and L. limprichtii. AB - The diversity in root chemicals and evolutionally neutral DNA regions in the complex of Ligularia duciformis, L. kongkalingensis, and L. nelumbifolia (the d/k/n complex) was studied using eight samples collected in central and northern Sichuan Province of China. Cacalol (14) and epicacalone (15), rearranged eremophilanes, were isolated from the complex for the first time. Two new phenylpropanoids were also obtained. Seven of the eight samples produced phenylpropanoids and the other produced lupeol alone. Two of the seven samples also produced furanoeremophilanes or their derivatives and one produced oplopanes. The geographical distribution of the sesquiterpene-producing populations suggests that the production of sesquiterpenes evolved independently in separate regions. L. limprichtii collected in northern Sichuan was also analyzed and its chemical composition and the sequence of internal transcribed spacers (ITSs) in the ribosomal RNA gene cluster were found to be similar to that in the d/k/n complex and L. yunnanensis, which are morphologically similar. PMID- 29186834 TI - Urinary Phthalate Concentrations in Mothers and Their Children in Ireland: Results of the DEMOCOPHES Human Biomonitoring Study. AB - Background: Phthalates are chemicals which are widespread in the environment. Although the impacts on health of such exposure are unclear, there is evidence of a possible impact on the incidence of a diverse range of diseases. Monitoring of human exposure to phthalates is therefore important. This study aimed to determine the extent of phthalate exposure among mothers and their children in both rural and urban areas in Ireland, and to identify factors associated with elevated concentrations. It formed part of the 'Demonstration of a study to Co ordinate and Perform Human Biomonitoring on a European Scale' (DEMOCOPHES) pilot biomonitoring study. Methods: the concentration of phthalate metabolites were determined from a convenience sample of 120 mother/child pairs. The median age of the children was 8 years. A questionnaire was used to collect information regarding lifestyle and environmental conditions of the children and mothers. Rigorous quality assurance within DEMOCOPHES guaranteed the accuracy and international comparability of results. Results: Phthalate metabolites were detected in all of the samples from both children and mothers. Concentrations were significantly higher in respondents from families with lower educational attainment and in those exposed to such items as polyvinyl chloride (PVC), fast food and personal care products (PCP). Conclusions: The study demonstrates that human biomonitoring for assessing exposure to phthalates can be undertaken in Ireland and that the exposure of the population is widespread. Further work will be necessary before the consequences of this exposure are understood. PMID- 29186835 TI - School Gardens: A Qualitative Study on Implementation Practices. AB - School gardens have beneficial effects on children's dietary behaviors but information on its implementation is scarce. The current study aimed to gain insight in implementation practices of school gardens and in perceptions of key members and children towards a school garden. We conducted twelve interviews involving 14 key members and five focus groups with 38 children from fifth to sixth grade (10-13 years old) in four primary schools in Ghent (Flanders, Belgium). We analyzed the interviews and focus groups in NVivo, using thematic analysis. School gardens were mainly initiated to involve children in nature, not to improve vegetable consumption. Participants were positive about having a school garden, experienced facilitating factors (e.g., adaptability of the garden, having a person responsible for the garden), but also various barriers (e.g., difficulties with startup, maintenance during summer holidays and integration in the school curriculum) and suggested some solutions (e.g., involving external organizations and parents, expanding the garden) and motivating factors for children (e.g., colorful plants, use of gloves). In order to improve implementation and to contribute to children's health, future school gardening projects should take the recommendations of key members and children into account. PMID- 29186836 TI - Autonomous Shepherding Behaviors of Multiple Target Steering Robots. AB - This paper presents a distributed coordination methodology for multi-robot systems, based on nearest-neighbor interactions. Among many interesting tasks that may be performed using swarm robots, we propose a biologically-inspired control law for a shepherding task, whereby a group of external agents drives another group of agents to a desired location. First, we generated sheep-like robots that act like a flock. We assume that each agent is capable of measuring the relative location and velocity to each of its neighbors within a limited sensing area. Then, we designed a control strategy for shepherd-like robots that have information regarding where to go and a steering ability to control the flock, according to the robots' position relative to the flock. We define several independent behavior rules; each agent calculates to what extent it will move by summarizing each rule. The flocking sheep agents detect the steering agents and try to avoid them; this tendency leads to movement of the flock. Each steering agent only needs to focus on guiding the nearest flocking agent to the desired location. Without centralized coordination, multiple steering agents produce an arc formation to control the flock effectively. In addition, we propose a new rule for collecting behavior, whereby a scattered flock or multiple flocks are consolidated. From simulation results with multiple robots, we show that each robot performs actions for the shepherding behavior, and only a few steering agents are needed to control the whole flock. The results are displayed in maps that trace the paths of the flock and steering robots. Performance is evaluated via time cost and path accuracy to demonstrate the effectiveness of this approach. PMID- 29186837 TI - Systematic Review and Meta-Analysis of Human Skin Diseases Due to Particulate Matter. AB - This study investigated the effects of particulate matter (PM) on human skin diseases by conducting a systematic review of existing literature and performing a meta-analysis. It considered articles reporting an original effect of PM on human skin. From among 918 articles identified, 13 articles were included for further consideration after manual screening of the articles resulted in the exclusion of articles that did not contain data, review articles, editorials, and also articles in languages other than English. Random-effects models and forest plots were used to estimate the effect of PM on the skin by Meta-Disc analysis. According to people's reports of exposure and negative skin effects (atopic dermatitis (AD), eczema, and skin aging, etc.) due to air pollution, the summary relative risk (odds ratio) of PM10 was determined to be 0.99 (95% confidence interval (CI) 0.89-1.11) whereas PM2.5 was determined to be 1.04 (95% CI 0.96 1.12). Simultaneously, there was a different extent of impact between PM10 and PM2.5 on atopic dermatitis (AD) for those of young age: the odds ratio of PM10 and PM2.5 were 0.96 (95% CI 0.83-1.11; I2 = 62.7%) and 1.05 (95% CI 0.95-1.16; I2 = 46%), respectively. Furthermore, the results suggest an estimated increase of disease incidence per 10 MUg/m3 PM of 1.01% (0.08-2.05) due to PM10 and 1.60% (0.45-2.82) due to PM2.5. Following the results, PM10 and PM2.5 are associated with increased risks of human skin diseases, especially AD, whose risk is higher in infants and school children. With its smaller size and a high concentration of metals, PM2.5 is more closely related to AD in younger people, compared to PM10. PMID- 29186838 TI - Role of MicroRNAs in TGF-beta Signaling Pathway-Mediated Pulmonary Fibrosis. AB - Pulmonary fibrosis is the most common form of interstitial lung disease. The transforming growth factor-beta (TGF-beta) signaling pathway is extensively involved in the development of pulmonary fibrosis by inducing cell differentiation, migration, invasion, or hyperplastic changes. Accumulating evidence indicates that microRNAs (miRNAs) are dysregulated during the initiation of pulmonary fibrosis. miRNAs are small noncoding RNAs functioning as negative regulators of gene expression at the post-transcriptional level. A number of miRNAs have been reported to regulate the TGF-beta signaling pathway and consequently affect the process of pulmonary fibrosis. A better understanding of the pro-fibrotic role of the TGF-beta signaling pathway and relevant miRNA regulation will shed light on biomedical research of pulmonary fibrosis. This review summarizes the current knowledge of miRNAs regulating the TGF-beta signaling pathway with relevance to pulmonary fibrosis. PMID- 29186839 TI - LSPR Coupling and Distribution of Interparticle Distances between Nanoparticles in Hydrogel on Optical Fiber End Face. AB - We report on a new localized surface plasmon resonance (LSPR)-based optical fiber (OF) architecture with a potential in sensor applications. The LSPR-OF system is fabricated by immobilizing gold nanoparticles (GNPs) in a hydrogel droplet polymerized on the fiber end face. This design has several advantages over earlier designs. It dramatically increase the number nanoparticles (NP) available for sensing, it offers precise control over the NP density, and the NPs are positioned in a true 3D aqueous environment. The OF-hydrogel design is also compatible with low-cost manufacturing. The LSPR-OF platform can measure volumetric changes in a stimuli-responsive hydrogel or measure binding to receptors on the NP surface. It can also be used as a two-parameter sensor by utilizing both effects. We present results from proof-of-concept experiments exploring the properties of LSPR and interparticle distances of the GNP-hydrogel OF design by characterizing the distribution of distances between NPs in the hydrogel, the refractive index of the hydrogel and the LSPR attributes of peak position, amplitude and linewidth for hydrogel deswelling controlled with pH solutions. PMID- 29186840 TI - Foodborne Norovirus State of Affairs in the EU Rapid Alert System for Food and Feed. AB - The European Union Rapid Alert System for Food and Feed (EU RASFF) database is an invaluable instrument for analyzing notifications involving norovirus in food. The aim of this work was to carry out a thorough research of the alert and border rejection notifications submitted in the RASFF database from its onset until 31 August 2017. Some conclusions of interest were: (i) Denmark, France, Italy, the Netherlands and Norway have contributed the majority of alert notifications as notifying countries, (ii) France and Serbia have been cited more often in alert notifications as countries of origin, (iii) Italy and Spain have submitted the majority of border rejection notifications, (iv) Third Countries implicated more frequently in border rejection notifications for norovirus in bivalve molluscs were Vietnam and Tunisia, whereas in fruits and vegetables were China and Serbia, (v) "risk dispersion" from norovirus-contaminated food was narrow since, in just over half of all alert notifications and all of the border rejection notifications, only up to three countries were involved, and (vi) both raw (oysters and berries) and cooked (mussels) food products can present a health risk to consumers. The information retrieved from the RASFF database on norovirus contaminated food could prove helpful in the planning of future norovirus risk analysis endeavors. PMID- 29186841 TI - Synthetic Secoisolariciresinol Diglucoside (LGM2605) Protects Human Lung in an Ex Vivo Model of Proton Radiation Damage. AB - Radiation therapy for the treatment of thoracic malignancies has improved significantly by directing of the proton beam in higher doses on the targeted tumor while normal tissues around the tumor receive much lower doses. Nevertheless, exposure of normal tissues to protons is known to pose a substantial risk in long-term survivors, as confirmed by our work in space relevant exposures of murine lungs to proton radiation. Thus, radioprotective strategies are being sought. We established that LGM2605 is a potent protector from radiation-induced lung toxicity and aimed in the current study to extend the initial findings of space-relevant, proton radiation-associated late lung damage in mice by looking at acute changes in human lung. We used an ex vivo model of organ culture where tissue slices of donor living human lung were kept in culture and exposed to proton radiation. We exposed donor human lung precision-cut lung sections (huPCLS), pretreated with LGM2605, to 4 Gy proton radiation and evaluated them 30 min and 24 h later for gene expression changes relevant to inflammation, oxidative stress, and cell cycle arrest, and determined radiation induced senescence, inflammation, and oxidative tissue damage. We identified an LGM2605-mediated reduction of proton radiation-induced cellular senescence and associated cell cycle changes, an associated proinflammatory phenotype, and associated oxidative tissue damage. This is a first report on the effects of proton radiation and of the radioprotective properties of LGM2605 on human lung. PMID- 29186843 TI - A 2.5D Map-Based Mobile Robot Localization via Cooperation of Aerial and Ground Robots. AB - Recently, there has been increasing interest in studying the task coordination of aerial and ground robots. When a robot begins navigation in an unknown area, it has no information about the surrounding environment. Accordingly, for robots to perform tasks based on location information, they need a simultaneous localization and mapping (SLAM) process that uses sensor information to draw a map of the environment, while simultaneously estimating the current location of the robot on the map. This paper aims to present a localization method based in cooperation between aerial and ground robots in an indoor environment. The proposed method allows a ground robot to reach accurate destination by using a 2.5D elevation map built by a low-cost RGB-D (Red Green and Blue-Depth) sensor and 2D Laser sensor attached onto an aerial robot. A 2.5D elevation map is formed by projecting height information of an obstacle using depth information obtained by the RGB-D sensor onto a grid map, which is generated by using the 2D Laser sensor and scan matching. Experimental results demonstrate the effectiveness of the proposed method for its accuracy in location recognition and computing speed. PMID- 29186845 TI - Banning Asbestos in New Zealand, 1936-2016, an 80-Year Long Saga. AB - The banning by the New Zealand Government of the import and export of asbestos containing products resulted from the interplay of a number of factors. At a personal level, there were the actions of the asbestos sufferers, their families and support groups. At the political level, there were the activities of progressive trade union groups representing the hazardous trades, such as labourers, construction workers and demolition workers, and at a Government level, there was a positive response to these public health pressures. The Prohibition Order 2016 concerning Imports and Exports (asbestos-containing products) was the outcome of this 80-year long saga. PMID- 29186842 TI - cfa-miR-143 Promotes Apoptosis via the p53 Pathway in Canine Influenza Virus H3N2 Infected Cells. AB - MicroRNAs regulate multiple aspects of the host response to viral infection. This study verified that the expression of cfa-miR-143 was upregulated in vivo and in vitro by canine influenza virus (CIV) H3N2 infection. To understand the role of cfa-miR-143 in CIV-infected cells, the target gene of cfa-miR-143 was identified and assessed for correlations with proteins involved in the apoptosis pathway. A dual luciferase reporter assay showed that cfa-miR-143 targets insulin-like growth factor binding protein 5 (Igfbp5). Furthermore, a miRNA agomir and antagomir of cfa-miR-143 caused the downregulation and upregulation of Igfbp5, respectively, in CIV-infected madin-darby canine kidney (MDCK) cells. This study demonstrated that cfa-miR-143 stimulated p53 and caspase3 activation and induced apoptosis via the p53 pathway in CIV H3N2-infected cells. In conclusion, CIV H3N2 induced the upregulation of cfa-miR-143, which contributes to apoptosis via indirectly activating the p53-caspase3 pathway. PMID- 29186844 TI - Upconversion Luminescence Sensitized pH-Nanoprobes. AB - Photon upconversion materials, featuring excellent photophysical properties, are promising for bio-medical research due to their low autofluorescence, non cytotoxicity, low photobleaching and high photostability. Upconversion based pH nanoprobes are attracting considerable interest due to their superiority over pH sensitive molecular indicators and metal nanoparticles. Herein, we review the advances in upconversion based pH-nanoprobes, the first time in the seven years since their discovery in 2009. With a brief discussion on the upconversion materials and upconversion processes, the progress in this field has been overviewed, along with the toxicity and biodistribution of upconversion materials for intracellular application. We strongly believe that this survey will encourage the further pursuit of intense research for designing molecular pH sensors. PMID- 29186846 TI - Dimension Reduction Aided Hyperspectral Image Classification with a Small-sized Training Dataset: Experimental Comparisons. AB - Hyperspectral images (HSI) provide rich information which may not be captured by other sensing technologies and therefore gradually find a wide range of applications. However, they also generate a large amount of irrelevant or redundant data for a specific task. This causes a number of issues including significantly increased computation time, complexity and scale of prediction models mapping the data to semantics (e.g., classification), and the need of a large amount of labelled data for training. Particularly, it is generally difficult and expensive for experts to acquire sufficient training samples in many applications. This paper addresses these issues by exploring a number of classical dimension reduction algorithms in machine learning communities for HSI classification. To reduce the size of training dataset, feature selection (e.g., mutual information, minimal redundancy maximal relevance) and feature extraction (e.g., Principal Component Analysis (PCA), Kernel PCA) are adopted to augment a baseline classification method, Support Vector Machine (SVM). The proposed algorithms are evaluated using a real HSI dataset. It is shown that PCA yields the most promising performance in reducing the number of features or spectral bands. It is observed that while significantly reducing the computational complexity, the proposed method can achieve better classification results over the classic SVM on a small training dataset, which makes it suitable for real time applications or when only limited training data are available. Furthermore, it can also achieve performances similar to the classic SVM on large datasets but with much less computing time. PMID- 29186847 TI - Economic Feasibility of Wireless Sensor Network-Based Service Provision in a Duopoly Setting with a Monopolist Operator. AB - We analyze the feasibility of providing Wireless Sensor Network-data-based services in an Internet of Things scenario from an economical point of view. The scenario has two competing service providers with their own private sensor networks, a network operator and final users. The scenario is analyzed as two games using game theory. In the first game, sensors decide to subscribe or not to the network operator to upload the collected sensing-data, based on a utility function related to the mean service time and the price charged by the operator. In the second game, users decide to subscribe or not to the sensor-data-based service of the service providers based on a Logit discrete choice model related to the quality of the data collected and the subscription price. The sinks and users subscription stages are analyzed using population games and discrete choice models, while network operator and service providers pricing stages are analyzed using optimization and Nash equilibrium concepts respectively. The model is shown feasible from an economic point of view for all the actors if there are enough interested final users and opens the possibility of developing more efficient models with different types of services. PMID- 29186848 TI - Adaptive Spatial Filter Based on Similarity Indices to Preserve the Neural Information on EEG Signals during On-Line Processing. AB - This work presents a new on-line adaptive filter, which is based on a similarity analysis between standard electrode locations, in order to reduce artifacts and common interferences throughout electroencephalography (EEG) signals, but preserving the useful information. Standard deviation and Concordance Correlation Coefficient (CCC) between target electrodes and its correspondent neighbor electrodes are analyzed on sliding windows to select those neighbors that are highly correlated. Afterwards, a model based on CCC is applied to provide higher values of weight to those correlated electrodes with lower similarity to the target electrode. The approach was applied to brain computer-interfaces (BCIs) based on Canonical Correlation Analysis (CCA) to recognize 40 targets of steady state visual evoked potential (SSVEP), providing an accuracy (ACC) of 86.44 +/- 2.81%. In addition, also using this approach, features of low frequency were selected in the pre-processing stage of another BCI to recognize gait planning. In this case, the recognition was significantly ( p < 0.01 ) improved for most of the subjects ( A C C >= 74.79 % ) , when compared with other BCIs based on Common Spatial Pattern, Filter Bank-Common Spatial Pattern, and Riemannian Geometry. PMID- 29186849 TI - New Possibilities of Substance Identification Based on THz Time Domain Spectroscopy Using a Cascade Mechanism of High Energy Level Excitation. AB - Using an experiment with thin paper layers and computer simulation, we demonstrate the principal limitations of standard Time Domain Spectroscopy (TDS) based on using a broadband THz pulse for the detection and identification of a substance placed inside a disordered structure. We demonstrate the spectrum broadening of both transmitted and reflected pulses due to the cascade mechanism of the high energy level excitation considering, for example, a three-energy level medium. The pulse spectrum in the range of high frequencies remains undisturbed in the presence of a disordered structure. To avoid false absorption frequencies detection, we apply the spectral dynamics analysis method (SDA method) together with certain integral correlation criteria (ICC). PMID- 29186850 TI - Optimal Power Allocation Strategy in a Joint Bistatic Radar and Communication System Based on Low Probability of Intercept. AB - In this paper, we investigate a low probability of intercept (LPI)-based optimal power allocation strategy for a joint bistatic radar and communication system, which is composed of a dedicated transmitter, a radar receiver, and a communication receiver. The joint system is capable of fulfilling the requirements of both radar and communications simultaneously. First, assuming that the signal-to-noise ratio (SNR) corresponding to the target surveillance path is much weaker than that corresponding to the line of sight path at radar receiver, the analytically closed-form expression for the probability of false alarm is calculated, whereas the closed-form expression for the probability of detection is not analytically tractable and is approximated due to the fact that the received signals are not zero-mean Gaussian under target presence hypothesis. Then, an LPI-based optimal power allocation strategy is presented to minimize the total transmission power for information signal and radar waveform, which is constrained by a specified information rate for the communication receiver and the desired probabilities of detection and false alarm for the radar receiver. The well-known bisection search method is employed to solve the resulting constrained optimization problem. Finally, numerical simulations are provided to reveal the effects of several system parameters on the power allocation results. It is also demonstrated that the LPI performance of the joint bistatic radar and communication system can be markedly improved by utilizing the proposed scheme. PMID- 29186851 TI - GNSS/Electronic Compass/Road Segment Information Fusion for Vehicle-to-Vehicle Collision Avoidance Application. AB - The increasing number of vehicles in modern cities brings the problem of increasing crashes. One of the applications or services of Intelligent Transportation Systems (ITS) conceived to improve safety and reduce congestion is collision avoidance. This safety critical application requires sub-meter level vehicle state estimation accuracy with very high integrity, continuity and availability, to detect an impending collision and issue a warning or intervene in the case that the warning is not heeded. Because of the challenging city environment, to date there is no approved method capable of delivering this high level of performance in vehicle state estimation. In particular, the current Global Navigation Satellite System (GNSS) based collision avoidance systems have the major limitation that the real-time accuracy of dynamic state estimation deteriorates during abrupt acceleration and deceleration situations, compromising the integrity of collision avoidance. Therefore, to provide the Required Navigation Performance (RNP) for collision avoidance, this paper proposes a novel Particle Filter (PF) based model for the integration or fusion of real-time kinematic (RTK) GNSS position solutions with electronic compass and road segment data used in conjunction with an Autoregressive (AR) motion model. The real-time vehicle state estimates are used together with distance based collision avoidance algorithms to predict potential collisions. The algorithms are tested by simulation and in the field representing a low density urban environment. The results show that the proposed algorithm meets the horizontal positioning accuracy requirement for collision avoidance and is superior to positioning accuracy of GNSS only, traditional Constant Velocity (CV) and Constant Acceleration (CA) based motion models, with a significant improvement in the prediction accuracy of potential collision.

AB - MicroRNAs (miRNAs) are small non-coding RNA molecules that post-transcriptionally regulate the translation of messenger RNAs. Given the crucial role of miRNAs in gene expression, genetic variants within miRNA-related sequences may affect miRNA function and contribute to disease risk. Osteoporosis is characterized by reduced bone mass, and bone mineral density (BMD) is a major diagnostic proxy to assess osteoporosis risk. Here, we aimed to identify miRNAs that are involved in BMD using data from recent genome-wide association studies (GWAS) on femoral neck, lumbar spine and forearm BMD. Of 242 miRNA-variants available in the GWAS data, we found rs11614913:C > T in the precursor miR-196a-2 to be significantly associated with femoral neck-BMD (p-value = 9.9 * 10-7, beta = -0.038) and lumbar spine-BMD (p-value = 3.2 * 10-11, beta = -0.061). Furthermore, our sensitivity analyses using the Rotterdam study data showed a sex-specific association of rs11614913 with BMD only in women. Subsequently, we highlighted a number of miR 196a-2 target genes, expressed in bone and associated with BMD, that may mediate the miRNA function in BMD. Collectively, our results suggest that miR-196a-2 may contribute to variations in BMD level. Further biological investigations will give more insights into the mechanisms by which miR-196a-2 control expression of BMD-related genes.

AB - Considering the great impact of a material's surface area on adsorption processes, hollow nanotube magnetic zinc oxide with a favorable surface area of 78.39 m2/g was fabricated with the assistance of microwave technology in the presence of poly vinyl alcohol (PVA) as a stabilizing agent followed by sonic precipitation of magnetite nano-particles. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) micrographs identified the nanotubes' morphology in the synthesized material with an average aspect ratio of 3. X-ray diffraction (XRD) analysis verified the combination of magnetite material with the hexagonal wurtzite structure of ZnO in the prepared material. The immobilization of magnetite nanoparticles on to ZnO was confirmed using vibrating sample magnetometry (VSM). The sorption affinity of the synthesized magnetic ZnO nanotube for phenolic compounds from aqueous solutions was examined as a function of various processing factors. The degree of acidity of the phenolic solution has great influence on the phenol sorption process on to magnetic ZnO. The calculated value of DeltaH0 designated the endothermic nature of the phenol uptake process on to the magnetic ZnO nanotubes. Mathematical modeling indicated a combination of physical and chemical adsorption mechanisms of phenolic compounds on to the fabricated magnetic ZnO nanotubes. The kinetic process correlated better with the second-order rate model compared to the first-order rate model. This result indicates the predominance of the chemical adsorption process of phenol on to magnetic ZnO nanotubes.

AB - Recently, the recycling of waste glass has become a worldwide issue in the reduction of waste and energy consumption. Waste glass can be utilized in construction materials, and understanding its effects on material properties is crucial in developing advanced materials. In this study, recycled crushed and expanded glasses are used as lightweight aggregates for concrete, and their relation to the material characteristics and properties is investigated using several approaches. Lightweight concrete specimens containing only crushed and expanded waste glass as fine aggregates are produced, and their pore and structural characteristics are examined using image-based methods, such as scanning electron microscopy (SEM), X-ray computed tomography (CT), and automated image analysis (RapidAir). The thermal properties of the materials are measured using both Hot Disk and ISOMET devices to enhance measurement accuracy. Mechanical properties are also evaluated, and the correlation between material characteristics and properties is evaluated. As a control group, a concrete specimen with natural fine sand is prepared, and its characteristics are compared with those of the specimens containing crushed and expanded waste glass aggregates. The obtained results support the usability of crushed and expanded waste glass aggregates as alternative lightweight aggregates. PMID- 29186857 TI - Techno-Economic Analysis of Biofuel Production from Macroalgae (Seaweed). AB - A techno-economic evaluation of bioenergy production from macroalgae was carried out in this study. Six different scenarios were examined for the production of different energy products and by-products. Seaweed was produced either via the longline method or the grid method. Final products of these scenarios were either ethanol from fermentation, or electricity from anaerobic digestion (AD). By products were digestate for AD, and animal feed, or electricity and digestate, for the fermentation pathway. Bioenergy breakeven selling prices were investigated according to the cost components and the feedstock supply chain, while suggestions for potential optimization of costs were provided. The lowest production level of dry seaweed to meet 0.93 ($/L) for ethanol fuel and 0.07 $/kW h for electricity was found to be 0.68 and 3.7 million tonnes (dry basis), respectively. At the moment, biofuel production from seaweed has been determined not to be economically feasible, but achieving economic production may be possible by lowering production costs and increasing the area under cultivation. PMID- 29186855 TI - Translational Aspects of Sphingolipid Metabolism in Renal Disorders. AB - Sphingolipids, long thought to be passive components of biological membranes with merely a structural role, have proved throughout the past decade to be major players in the pathogenesis of many human diseases. The study and characterization of several genetic disorders like Fabry's and Tay Sachs, where sphingolipid metabolism is disrupted, leading to a systemic array of clinical symptoms, have indeed helped elucidate and appreciate the importance of sphingolipids and their metabolites as active signaling molecules. In addition to being involved in dynamic cellular processes like apoptosis, senescence and differentiation, sphingolipids are implicated in critical physiological functions such as immune responses and pathophysiological conditions like inflammation and insulin resistance. Interestingly, the kidneys are among the most sensitive organ systems to sphingolipid alterations, rendering these molecules and the enzymes involved in their metabolism, promising therapeutic targets for numerous nephropathic complications that stand behind podocyte injury and renal failure. PMID- 29186858 TI - Differential Expression of Nitric Oxide Synthase Isoforms nNOS and iNOS in Patients with Non-Segmental Generalized Vitiligo. AB - Nitric oxide (NO) is involved in several biological processes, but its role in human melanogenesis is still not well understood. Exposure to UVA and UVB induces nitric oxide production in keratinocytes and melanocytes through the activation of constitutive nitric oxide synthase, increasing tyrosinase activity and melanin synthesis, whereas inducible nitric oxide synthase over expression might be involved in hypopigmentary disorders. The aim of this study was to evaluate whether inducible nitric oxide synthase and neuronal nitric oxide synthase expression were modified in vitiligo skin compared to healthy controls. Skin biopsies were obtained from inflammatory/lesional and white/lesional skin in 12 patients with active, non-segmental vitiligo; site-matched biopsies of normal skin from eight patients were used as controls. Nitric oxide synthase isoforms expression was evaluated by confocal laser scanning microscopy and Western Blot analysis. Inducible nitric oxide synthase expression was significantly increased in inflammatory/lesional skin compared to healthy skin; melanocytes showed a moderate neuronal nitric oxide synthase expression in white/lesional skin, demonstrating that metabolic function still goes on. The obtained data demonstrated that vitiligo lesions were characterized by modifications of nitric oxide synthase isoforms, thus confirming the hypothesis that nitric oxide imbalance is involved in vitiligo and supporting the idea that nitric oxide synthase inhibitors might be used as a possible therapeutic approach for the management of vitiligo. PMID- 29186859 TI - Peanuts, Aflatoxins and Undernutrition in Children in Sub-Saharan Africa. AB - Peanuts (Arachis hypogaea) is an important and affordable source of protein in most of Sub-Saharan Africa (SSA) and a popular commodity and raw material for peanut butter, paste and cooking oil. It is a popular ingredient for foods used at the point of weaning infants from mother's milk. It is at this critical point that childhood undernutrition occurs and the condition manifests as stunting, wasting and growth restriction and accounts for nearly half of all deaths in children under five years of age in SSA. Undernutrition is multi-factorial but weaning foods contaminated with microbiological agents (bacteria and fungi) and natural toxins have been shown to play a big part. While peanuts may provide good nutrition, they are also highly prone to contamination with mycotoxigenic fungi. The high nutritive value of peanuts makes them a perfect substrate for fungal growth and potential aflatoxin contamination. Aflatoxins are highly carcinogenic and mutagenic mycotoxins. This article reviews the nutritional value and aflatoxin contamination of peanuts, the role they play in the development of childhood malnutrition (including the different theories of aetiology) and immunological problems in children. We also discuss the control strategies that have been explored and advocacy work currently taking shape in Africa to create more awareness of aflatoxins and thus combat their occurrence with the goal of reducing exposure and enhancing trade and food safety. PMID- 29186860 TI - BCL11A mRNA Targeting by miR-210: A Possible Network Regulating gamma-Globin Gene Expression. AB - The involvement of microRNAs in the control of repressors of human gamma-globin gene transcription has been firmly demonstrated, as described for the miR-486-3p mediated down-regulation of BCL11A. On the other hand, we have reported that miR 210 is involved in erythroid differentiation and, possibly, in gamma-globin gene up-regulation. In the present study, we have identified the coding sequence of BCL11A as a possible target of miR-210. The following results sustain this hypothesis: (a) interactions between miR-210 and the miR-210 BCL11A site were demonstrated by SPR-based biomolecular interaction analysis (BIA); (b) the miR 210 site of BCL11A is conserved through molecular evolution; (c) forced expression of miR-210 leads to decrease of BCL11A-XL and increase of gamma-globin mRNA content in erythroid cells, including erythroid precursors isolated from beta-thalassemia patients. Our study suggests that the coding mRNA sequence of BCL11A can be targeted by miR-210. In addition to the theoretical point of view, these data are of interest from the applied point of view, supporting a novel strategy to inhibit BCL11A by mimicking miR-210 functions, accordingly with the concept supported by several papers and patent applications that inhibition of BCL11A is an efficient strategy for fetal hemoglobin induction in the treatment of beta-thalassemia. PMID- 29186861 TI - Mental Health of the Prison Medical Workers (PMWs) and Influencing Factors in Jiangxi, China. AB - Prison medical workers (PMWs) are critically important, but they are also vulnerable to psychological problems. Currently, there is no study on examining PMWs' mental health conditions and possible influencing factors in China. Hence, we conducted this cross-sectional survey, aiming to understand the mental health status of the PMWs and related impact factors in Jiangxi province of China. We employed the Chinese version of the Symptom Checklist-90-R (SCL-90-R) to assess the mental disorders and psychological health conditions of PMWs in Jiangxi. The t tests were used to compare the differences for the average score of SCL-90-R between the Chinese general population and targeted PMWs of this study. Multivariable logistic regression analyses were conducted to identify the main factors associated with overall detection rate of PMWs' psychological health conditions. The scores of four dimensions (somatization, obsessive-compulsive symptoms, anxiety, and paranoid ideation) were significantly higher than the Chinese national norm, and the total positive rate was 49.09% among the PMWs. Gender, marital status, age, and length of employment are identified to be the most significant predictors to affect PMWs' mental health. Positive correlations between each of the nine dimensions of the SCL-90-R have been verified. This study demonstrated for the first time that PMWs are facing mental health risk and suffering serious psychological problems with psychopathology symptoms, which has become a growing concern in China. Our current findings suggest a need for more in-depth studies on this subject going forward to validate our conclusions and also to identify more impact factors, since such studies and knowledge of PMWs' mental health and influencing factors are very limited in China. PMID- 29186856 TI - Zinc as a Gatekeeper of Immune Function. AB - After the discovery of zinc deficiency in the 1960s, it soon became clear that zinc is essential for the function of the immune system. Zinc ions are involved in regulating intracellular signaling pathways in innate and adaptive immune cells. Zinc homeostasis is largely controlled via the expression and action of zinc "importers" (ZIP 1-14), zinc "exporters" (ZnT 1-10), and zinc-binding proteins. Anti-inflammatory and anti-oxidant properties of zinc have long been documented, however, underlying mechanisms are still not entirely clear. Here, we report molecular mechanisms underlying the development of a pro-inflammatory phenotype during zinc deficiency. Furthermore, we describe links between altered zinc homeostasis and disease development. Consequently, the benefits of zinc supplementation for a malfunctioning immune system become clear. This article will focus on underlying mechanisms responsible for the regulation of cellular signaling by alterations in zinc homeostasis. Effects of fast zinc flux, intermediate "zinc waves", and late homeostatic zinc signals will be discriminated. Description of zinc homeostasis-related effects on the activation of key signaling molecules, as well as on epigenetic modifications, are included to emphasize the role of zinc as a gatekeeper of immune function. PMID- 29186862 TI - Study on the Anti-Poison Performance of Al-Y-P Master Alloy for Impurity Ca in Aluminum Alloys. AB - In this article, the anti-poison performance of novel Al-6Y-2P master alloy for impurity Ca in hypereutectic Al-Si alloys was investigated in detail. According to the microstructural analysis, it can be found that the primary Si and eutectic Si particles could be relatively modified and refined. In order to investigate the influence mechanism of Ca on the limited refinement performance of Al-6Y-2P master alloy, types of Al-xSi-2Ca-3Y-1P (x = 0, 6, 12, 18, and 30) alloys were prepared. It is observed that Ca takes the form of more stable Ca3P2 compounds by reacting with YP, and the surface of Ca3P2 particles are unsmooth, and even some have wrinkles in Al Al-2Ca-3Y-1P alloy. With the increase of Si content in Al-xSi 2Ca-3Y-1P (x = 6, 12, 18 and 30) systems, the multi-encapsulation structures, i.e., the phosphide (AlP and YP), hexagonal Al2Si2Ca, the Al3Si2Y2 or primary Si from inside to outside in order were examined.The excapsulation of YP and AlP caused by Al2Si2Ca might be the reason for the limited refinement effect of Al-6Y 2P master alloy for hypereutectic Al-18Si alloys. PMID- 29186864 TI - Brazilian Citizens: Expectations Regarding Dairy Cattle Welfare and Awareness of Contentious Practices. AB - The primary aim of this study was to explore attitudes of urban Brazilian citizens about dairy production. A secondary aim was to determine their knowledge and attitudes about four potentially contentious routine dairy cattle management practices: early cow-calf separation; zero-grazing; culling of newborn male calves; and dehorning without pain mitigation. To address the first aim 40 participants were interviewed using open-ended semi-structured questions designed to probe their views and attitudes about dairy production in Brazil, and 300 participants answered a questionnaire that included an open-ended question about the welfare of dairy cattle. Primary concerns reported by the participants centered on milk quality, which included the rejection of any chemical additives, but also animal welfare, environmental and social issues. The interviewees rarely mentioned animal welfare directly but, when probed, expressed several concerns related to this topic. In particular, participants commented on factors that they perceived to influence milk quality, such as good animal health, feeding, clean facilities, and the need to avoid or reduce the use of drugs, hormones and pesticides, the avoidance of pain, frustration and suffering, and the ability of the animals to perform natural behaviors. To address our second aim, participants were asked questions about the four routine management practices. Although they self-reported being largely unaware of these practices, the majority of the participants rejected these practices outright. These data provide insight that animal welfare may be an important issue for members of the public. Failure to consider this information may increase the risk that certain dairy production practices may not be socially sustainable once lay citizens become aware of them. PMID- 29186863 TI - Paraneoplastic Pemphigus: Insight into the Autoimmune Pathogenesis, Clinical Features and Therapy. AB - Paraneoplastic pemphigus is a rare autoimmune skin disease that is always associated with a neoplasm. Usually, oral, skin, and mucosal lesions are the earliest manifestations shown by paraneoplastic pemphigus patients. The pathogenesis of paraneoplastic pemphigus is not yet completely understood, although some immunological aspects have been recently clarified. Because of its rarity, several diagnostic criteria have been proposed. Besides, several diagnostic procedures have been used for the diagnosis, including indirect immunofluorescence, direct immunofluorescence, and ELISA. We reviewed the most recent literature, searching on PubMed "paraneoplastic pemphigus". We included also papers in French, German, and Spanish. We found 613 papers for "paraneoplastic pemphigus". Among them, 169 were review papers. Because of its varying clinical features, paraneoplastic pemphigus still represents a challenge for clinicians. Furthermore, diagnosis and management of paraneoplastic pemphigus requires close collaboration between physicians, including dermatologist, oncologist, and otorhinolaryngologist. PMID- 29186865 TI - Role of Vitamin D in Maintaining Renal Epithelial Barrier Function in Uremic Conditions. AB - As current kidney replacement therapies are not efficient enough for end-stage renal disease (ESRD) treatment, a bioartificial kidney (BAK) device, based on conditionally immortalized human proximal tubule epithelial cells (ciPTEC), could represent an attractive solution. The active transport activity of such a system was recently demonstrated. In addition, endocrine functions of the cells, such as vitamin D activation, are relevant. The organic anion transporter 1 (OAT-1) overexpressing ciPTEC line presented 1alpha-hydroxylase (CYP27B1), 24-hydroxylase (CYP24A1) and vitamin D receptor (VDR), responsible for vitamin D activation, degradation and function, respectively. The ability to produce and secrete 1alpha,25-dihydroxy-vitamin D3, was shown after incubation with the precursor, 25 hydroxy-vitamin D3. The beneficial effect of vitamin D on cell function and behavior in uremic conditions was studied in the presence of an anionic uremic toxins mixture. Vitamin D could restore cell viability, and inflammatory and oxidative status, as shown by cell metabolic activity, interleukin-6 (IL-6) levels and reactive oxygen species (ROS) production, respectively. Finally, vitamin D restored transepithelial barrier function, as evidenced by decreased inulin-FITC leakage in biofunctionalized hollow fiber membranes (HFM) carrying ciPTEC-OAT1. In conclusion, the protective effects of vitamin D in uremic conditions and proven ciPTEC-OAT1 endocrine function encourage the use of these cells for BAK application. PMID- 29186867 TI - Outlook on the Application of Metal-Liganded Bioactives for Stimuli-Responsive Release. AB - Direct metal-liganded bioactive coordination complexes are known to be sensitive to stimuli such as pH, light, ion activation, or redox cues. This results in the controlled release of the bioactive(s). Compared to other drug delivery strategies based on metal complexation, this type of coordination negates a multi step drug loading methodology and offers customized physiochemical properties through judicious choice of modulating ancillary ligands. Bioactive release depends on simple dissociative kinetics. Nonetheless, there are challenges encountered when translating the pure coordination chemistry into the biological and physiological landscape. The stability of the metal-bioactive complex in the biological milieu may be compromised, disrupting the stimuli-responsive release mechanism, with premature release of the bioactive. Research has therefore progressed to the incorporation of metal-liganded bioactives with established drug delivery strategies to overcome these limitations. This review will highlight and critically assess current research interventions in order to predict the direction that pharmaceutical scientists could pursue to arrive at tailored and effective metal-liganded bioactive carriers for stimuli-responsive drug release. PMID- 29186866 TI - TGF-beta1 in Vascular Wall Pathology: Unraveling Chronic Venous Insufficiency Pathophysiology. AB - Chronic venous insufficiency and varicose veins occur commonly in affluent countries and are a socioeconomic burden. However, there remains a relative lack of knowledge about venous pathophysiology. Various theories have been suggested, yet the molecular sequence of events is poorly understood. Transforming growth factor-beta one (TGF-beta1) is a highly complex polypeptide with multifunctional properties that has an active role during embryonic development, in adult organ physiology and in the pathophysiology of major diseases, including cancer and various autoimmune, fibrotic and cardiovascular diseases. Therefore, an emphasis on understanding its signaling pathways (and possible disruptions) will be an essential requirement for a better comprehension and management of specific diseases. This review aims at shedding more light on venous pathophysiology by describing the TGF-beta1 structure, function, activation and signaling, and providing an overview of how this growth factor and disturbances in its signaling pathway may contribute to specific pathological processes concerning the vessel wall which, in turn, may have a role in chronic venous insufficiency. PMID- 29186868 TI - Could -79 degrees C Spray-Type Cryotherapy Be an Effective Monotherapy for the Treatment of Keloid? AB - Cryotherapy has been regarded as an effective modality for the treatment of keloids, and the spray-type device is one of the novel cryotherapeutic units. However, the biological mechanisms and therapeutic effects of this technique are incompletely studied. We evaluated the clinical efficacy of our cryotherapy protocol with molecular and pathologic evidence for the treatment of keloids. We evenly split each of ten keloid lesions into a non-treated (C-) and treated (C+) area; the C+ area was subjected to two freeze-thaw cycles of spray-type cryotherapy using -79 degrees C spray-type CryoPenTM. This treatment was repeated after an interval of two weeks. The proliferation and migration abilities of the fibroblasts isolated from the dermis under the cryotherapy treated or untreated keloid tissues (at least 5 mm deep) were compared and pathologic findings of the full layer were evaluated. Molecular analysis revealed that the number of dermal fibroblasts was significantly higher in C+ group as compared with C- group. The dermal fibroblasts from C+ group showed more than two fold increase in the migration ability as compared with the fibroblasts from C- group. The expression of matrix metallopeptidase 9 was increased by more than two fold and a significant increase in transforming growth factor beta 1 expression and Smad2/3 phosphorylation level was observed in C+ group. C+ group showed more extensive lymphoplasmacytic infiltration with thicker fibrosis and occasional "proliferating core collagen" as compared with C- group. Thus, -79 degrees C spray-type cryotherapy is ineffective as a monotherapy and should be used in combination with intralesional corticosteroids or botulinum toxin A for favourable outcomes in the treatment of thick keloids. PMID- 29186869 TI - Screen-Printed Graphite Electrodes as Low-Cost Devices for Oxygen Gas Detection in Room-Temperature Ionic Liquids. AB - Screen-printed graphite electrodes (SPGEs) have been used for the first time as platforms to detect oxygen gas in room-temperature ionic liquids (RTILs). Up until now, carbon-based SPEs have shown inferior behaviour compared to platinum and gold SPEs for gas sensing with RTIL solvents. The electrochemical reduction of oxygen (O2) in a range of RTILs has therefore been explored on home-made SPGEs, and is compared to the behaviour on commercially-available carbon SPEs (C SPEs). Six common RTILs are initially employed for O2 detection using cyclic voltammetry (CV), and two RTILs ([C2mim][NTf2] and [C4mim][PF6]) chosen for further detailed analytical studies. Long-term chronoamperometry (LTCA) was also performed to test the ability of the sensor surface for real-time gas monitoring. Both CV and LTCA gave linear calibration graphs-for CV in the 10-100% vol. range, and for LTCA in the 0.1-20% vol. range-on the SPGE. The responses on the SPGE were far superior to the commercial C-SPEs; more instability in the electrochemical responses were observed on the C-SPEs, together with some breaking-up or dissolution of the electrode surface materials. This study highlights that not all screen-printed ink formulations are compatible with RTIL solvents for longer-term electrochemical experiments, and that the choice of RTIL is also important. Overall, the low-cost SPGEs appear to be promising platforms for the detection of O2, particularly in [C4mim][PF6]. PMID- 29186870 TI - Dietary Supplementation with Lactobacillus casei Alleviates Lipopolysaccharide Induced Liver Injury in a Porcine Model. AB - This study aims to determine whether Lactobacillus casei (L. casei) could relieve liver injury in piglets challenged with lipopolysaccharide (LPS). Piglets were randomly allocated into one of the three groups: control, LPS, and L. casei. The control and LPS groups were fed a corn- and soybean meal-based diet, whereas the L. casei group was fed the basal diet supplemented with 6 * 106 cfu/g L. casei. On Day 31 of the trial, piglets in the LPS and L. casei groups received intraperitoneal administration of LPS (100 ug/kg body weight), while the control group received the same volume of saline. Blood and liver samples were collected for analysis. Results showed that L. casei supplementation decreased the feed/gain ratio (p = 0.027) and diarrhea incidence (p < 0.001), and attenuated LPS-induced liver histomorphological abnormalities. Compared with the control group, LPS challenge dramatically increased glutamyl transpeptidase activity (p = 0.001) in plasma as well as the concentrations of Interleukin 6 (IL-6) (p = 0.048), Tumor necrosis factor-alpha (TNF-alpha) (p = 0.041), and Malondialdehyde (MDA) (p = 0.001) in the liver, while decreasing the hepatic SOD activity. LPS also increased (p < 0.05) the mRNA levels for IL-6, IL-8, TNF-alpha, Toll-like receptors 4 (TLR4), Nuclear factor kappaB (NF-kappaB) and Heat shock protein 70 (HSP70) in the liver. The adverse effects of LPS challenge were ameliorated by L. casei supplementation. In conclusion, dietary L. casei alleviates LPS-induced liver injury via reducing pro-inflammatory cytokines and increasing anti oxidative capacity. PMID- 29186871 TI - Plasmonic Optical Fiber-Grating Immunosensing: A Review. AB - Plasmonic immunosensors are usually made of a noble metal (in the form of a film or nanoparticles) on which bioreceptors are grafted to sense analytes based on the antibody/antigen or other affinity mechanism. Optical fiber configurations are a miniaturized counterpart to the bulky Kretschmann prism and allow easy light injection and remote operation. To excite a surface plasmon (SP), the core guided light is locally outcoupled. Unclad optical fibers were the first configurations reported to this end. Among the different architectures able to bring light in contact with the surrounding medium, a great quantity of research is today being conducted on metal-coated fiber gratings photo-imprinted in the fiber core, as they provide modal features that enable SP generation at any wavelength, especially in the telecommunication window. They are perfectly suited for use with cost-effective high-resolution interrogators, allowing both a high sensitivity and a low limit of detection to be reached in immunosensing. This paper will review recent progress made in this field with different kinds of gratings: uniform, tilted and eccentric short-period gratings as well as long period fiber gratings. Practical cases will be reported, showing that such sensors can be used in very small volumes of analytes and even possibly applied to in vivo diagnosis. PMID- 29186872 TI - Pre-Clinical Tests of an Integrated CMOS Biomolecular Sensor for Cardiac Diseases Diagnosis. AB - Coronary artery disease and its related complications pose great threats to human health. In this work, we aim to clinically evaluate a CMOS field-effect biomolecular sensor for cardiac biomarkers, cardiac-specific troponin-I (cTnI), N terminal prohormone brain natriuretic peptide (NT-proBNP), and interleukin-6 (IL 6). The CMOS biosensor is implemented via a standard commercialized 0.35 MUm CMOS process. To validate the sensing characteristics, in buffer conditions, the developed CMOS biosensor has identified the detection limits of IL-6, cTnI, and NT-proBNP as being 45 pM, 32 pM, and 32 pM, respectively. In clinical serum conditions, furthermore, the developed CMOS biosensor performs a good correlation with an enzyme-linked immuno-sorbent assay (ELISA) obtained from a hospital central laboratory. Based on this work, the CMOS field-effect biosensor poses good potential for accomplishing the needs of a point-of-care testing (POCT) system for heart disease diagnosis. PMID- 29186873 TI - Thermoluminescence as a Research Tool to Investigate Luminescence Mechanisms. AB - Thermally stimulated luminescence (TSL) is known as a technique used in radiation dosimetry and dating. However, since the luminescence is very sensitive to the defects in a solid, it can also be used in material research. In this review, it is shown how TSL can be used as a research tool to investigate luminescent characteristics and underlying luminescent mechanisms. First, some basic characteristics and a theoretical background of the phenomenon are given. Next, methods and difficulties in extracting trapping parameters are addressed. Then, the instrumentation needed to measure the luminescence, both as a function of temperature and wavelength, is described. Finally, a series of very diverse examples is given to illustrate how TSL has been used in the determination of energy levels of defects, in the research of persistent luminescence phosphors, and in phenomena like band gap engineering, tunnelling, photosynthesis, and thermal quenching. It is concluded that in the field of luminescence spectroscopy, thermally stimulated luminescence has proven to be an experimental technique with unique properties to study defects in solids. PMID- 29186874 TI - Do Cervical Cancer Patients Diagnosed with Opportunistic Screening Live Longer? An Arkhangelsk Cancer Registry Study. AB - The aim of the current study was to compare cervical cancer (SS) patients diagnosed with and without screening in terms of: (i) sociodemographic and clinical characteristics; (ii) factors associated with survival; and (iii), and levels of risk. A registry-based study was conducted using data from the Arkhangelsk Cancer Registry. It included women with newly diagnosed malignant neoplasm of the uterine cervix during the period of 1 January 2005 to 11 November 2016 (N = 1548). The Kaplan-Meier method, the log-rank test, and Cox regression were applied. Most participants who were diagnosed by screening were at stage I and died less frequently from CC than those diagnosed without screening. The latter group was also diagnosed with SS at a younger age and died younger. Younger individuals and urban residents diagnosed with stage I and II, squamous cell carcinoma had longer survival times. Cox regression modeling indicated that the hazard ratio for death among women with CC diagnosed without screening was 1.61 (unadjusted) and 1.37 (adjusted). CC diagnosed by screening, cancer stage, patient residence, histological tumor type, and age at diagnosis were independent prognostic variables of longer survival time with CC. Diagnosis of CC made within a screening program improved survival. PMID- 29186875 TI - Distribution and Inferred Evolutionary Characteristics of a Chimeric ssDNA Virus Associated with Intertidal Marine Isopods. AB - Aquatic invertebrates are common reservoirs of a rapidly expanding group of circular Rep-encoding ssDNA (CRESS-DNA) viruses. This study identified and explored the phylogenetic relationship between novel CRESS-DNA viral genotypes associated with Pacific intertidal isopods Idotea wosnesenskii, Idotea resecata, and Gnorimosphaeroma oregonensis. One genotype associated with I. wosnesenskii, IWaV278, shared sequence similarity and genomic features with Tombusviridae (ssRNA) and Circoviridae (ssDNA) genomes and was putatively assigned to the Cruciviridae clade comprising chimeric viruses. The complete genome of IWaV278 (3478 nt) was computationally completed, validated via Sanger sequencing, and exhibited sequence conservation and codon usage patterns analogous to other members of the Cruciviridae. Viral surveillance (qPCR) indicated that this virus was temporally transient (present in 2015, but not 2017), specific to I. wosnesenskii at a single collection site (Washington, DC, USA), more prevalent among male specimens, and frequently detected within exoskeletal structures. 18S rRNA sequences identified two alveolate protists associated with IWaV278-positive tissues and mechanical epibiont removal of ciliated exoskeletal structures eliminated viral detection, suggesting that the putative host of IWaV278 may be an epibiont of I. wosnesenskii. This investigation provides additional phylogenetic evidence to resolve Cruciviridae evolution and offers insight into the biogeography, specificity, and potential host of a crucivirus genotype.

Mealybugs growing on Nerium oleander have been treated using PTW after being transferred to Petri dishes, thus avoiding possible buffering effects that might occur in an in-situ study. When treating tap water with a dielectric barrier discharge for several minutes (1, 3, 5 and 10 min) a distinct acidification of the water can be determined, resulting in a pH value of 1.8 after 10 min treatment. The efficacies of the treated tap water samples were compared to the efficacies achieved using classically acidified water. The classical acidification of tap water was carried out using nitric acid and hydrochloric acid to see any possible influences of the salt of the acid in question. The application of PTW revealed high mortality rates of approx. 90% after an observation period of 24 h. PTW appears promising for the treatment of smaller plant stock and commodities as produced by small scale farmers or in greenhouses as an environmentally friendly substitute or supplement to conventional pesticides. PMID- 29186878 TI - Dynamic Obstacle Avoidance for Unmanned Underwater Vehicles Based on an Improved Velocity Obstacle Method. AB - In view of a dynamic obstacle environment with motion uncertainty, we present a dynamic collision avoidance method based on the collision risk assessment and improved velocity obstacle method. First, through the fusion optimization of forward-looking sonar data, the redundancy of the data is reduced and the position, size and velocity information of the obstacles are obtained, which can provide an accurate decision-making basis for next-step collision avoidance. Second, according to minimum meeting time and the minimum distance between the obstacle and unmanned underwater vehicle (UUV), this paper establishes the collision risk assessment model, and screens key obstacles to avoid collision. Finally, the optimization objective function is established based on the improved velocity obstacle method, and a UUV motion characteristic is used to calculate the reachable velocity sets. The optimal collision speed of UUV is searched in velocity space. The corresponding heading and speed commands are calculated, and outputted to the motion control module. The above is the complete dynamic obstacle avoidance process. The simulation results show that the proposed method can obtain a better collision avoidance effect in the dynamic environment, and has good adaptability to the unknown dynamic environment. PMID- 29186876 TI - Melatonin Improves the Quality of Inferior Bovine Oocytes and Promoted Their Subsequent IVF Embryo Development: Mechanisms and Results. AB - The inferior oocytes (IOs), which are not suitable for embryo development, occupy roughly one-third or more of the collected immature bovine oocytes. The IOs are usually discarded from the in vitro bovine embryo production process. Improving the quality of the inferior oocytes (IOs) and make them available in in vitro embryo production would have important biological, as well as commercial, value. This study was designed to investigate whether melatonin could improve the quality of IOs and make them usable in the in vitro maturation (IVM) and subsequent (in vitro fertilization) IVF embryo development. The results indicated that: the maturation rate of IOs and their subsequent IVF embryo developments were impaired compared to cumulus-oocyte complexes and melatonin treatment significantly improved the quality of IOs, as well as their IVF and embryo developments. The potential mechanisms are that: (1) melatonin reduced reactive oxygen species (ROS) and enhanced glutathione (GSH) levels in the IOs, thereby protecting them from oxidative stress; (2) melatonin improved mitochondrial normal distribution and function to increase ATP level in IOs; and (3) melatonin upregulated the expression of ATPase 6, BMP-15, GDF-9, SOD-1, Gpx-4, and Bcl-2, which are critical genes for oocyte maturation and embryo development and downregulated apoptotic gene expression of caspase-3. PMID- 29186880 TI - Relation between the Disability of the Arm, Shoulder and Hand Score and Muscle Strength in Post-Cardiac Surgery Patients. AB - Background: The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire is a valid and reliable patient-reported outcome measure. DASH can be assessed by self-reported upper extremity disability and symptoms. We aimed to examine the relationship between the physiological outcome of muscle strength and the DASH score after cardiac surgery. Methods: This cross-sectional study assessed 50 consecutive cardiac patients that were undergoing cardiac surgery. Physiological outcomes of handgrip strength and knee extensor muscle strength and the DASH score were measured at one month after cardiac surgery and were assessed. Results were analyzed using Spearman correlation coefficients. Results: The final analysis comprised 43 patients (men: 32, women: 11; age: 62.1 +/- 9.1 years; body mass index: 22.1 +/- 4.7 kg/m2; left ventricular ejection fraction: 53.5 +/- 13.7%). Respective handgrip strength, knee extensor muscle strength, and DASH score were 27.4 +/- 8.3 kgf, 1.6 +/- 0.4 Nm/kg, and 13.3 +/- 12.3, respectively. The DASH score correlated negatively with handgrip strength (r = -0.38, p = 0.01) and with knee extensor muscle strength (r = -0.32, p = 0.04). Conclusion: Physiological outcomes of both handgrip strength and knee extensor muscle strength correlated negatively with the DASH score. The DASH score appears to be a valuable tool with which to assess cardiac patients with poor physiological outcomes, particularly handgrip strength as a measure of upper extremity function, which is probably easier to follow over time than lower extremity function after patients complete cardiac rehabilitation. PMID- 29186881 TI - A Novel Strategy for Quantitative Analysis of Major Ginsenosides in Panacis Japonici Rhizoma with a Standardized Reference Fraction. AB - Panacis Japonici Rhizoma (Zhu-Jie-Shen in Chinese), the root of P. japonicus C.A. Mey., is commonly used in traditional Chinese Medicine. Saponins are the major bioactive compounds in this herb. The similarity of polarity and structure of the natural products in herb caused the difficulty of purification and resulted in the shortage and high cost of the reference compounds, which has greatly hindered efforts toward quantification in quality control. A novel strategy using a standardized reference fraction for qualification of the major saponins in Panacis Japonici Rhizoma was proposed to easily and effectively control the quality of PJR. The strategy is feasible and reliable, and the methodology of the developed approach is also validated. The standardized reference fraction was used for quantification, which might solve the shortage of the pure reference compounds in the quality control of herbal medicines. PMID- 29186879 TI - The Weak Spots in Contemporary Science (and How to Fix Them). AB - In this review, the author discusses several of the weak spots in contemporary science, including scientific misconduct, the problems of post hoc hypothesizing (HARKing), outcome switching, theoretical bloopers in formulating research questions and hypotheses, selective reading of the literature, selective citing of previous results, improper blinding and other design failures, p-hacking or researchers' tendency to analyze data in many different ways to find positive (typically significant) results, errors and biases in the reporting of results, and publication bias. The author presents some empirical results highlighting problems that lower the trustworthiness of reported results in scientific literatures, including that of animal welfare studies. Some of the underlying causes of these biases are discussed based on the notion that researchers are only human and hence are not immune to confirmation bias, hindsight bias, and minor ethical transgressions. The author discusses solutions in the form of enhanced transparency, sharing of data and materials, (post-publication) peer review, pre-registration, registered reports, improved training, reporting guidelines, replication, dealing with publication bias, alternative inferential techniques, power, and other statistical tools. PMID- 29186882 TI - Finite Element Analysis of Tunable Composite Tubes Reinforced with Auxetic Structures. AB - A tubular composite structure that is built of two materials, characterized by different Young moduli, is analysed in this paper. The Young's modulus of one of these materials can be controlled by external conditions e.g., magnetic or electric field, temperature etc. The geometry of the reinforcement is based on typical auxetic re-entrant honeycomb cellular structure. The influence of this external factor on the behaviour of the stretched tube is analysed in this paper. Also, the possibility of creating a tubular composite structure whose cross section is either shrinking or expanding, while stretching the tube is presented. PMID- 29186883 TI - Consumers in a Sustainable Food Supply Chain (COSUS): Understanding Consumer Behavior to Encourage Food Waste Reduction. AB - Consumers are directly and indirectly responsible for a significant fraction of food waste which, for a large part, could be avoided if they were willing to accept food that is suboptimal, i.e., food that deviates in sensory characteristics (odd shape, discoloration), or that has a best-before date which is approaching or has passed, but that is still perfectly fine to eat. The choice to accept or discard suboptimal food is taken either before or after purchase (hence, in the retail store or in the household). The aim of the European research project COSUS (Consumers in a sustainable food supply chain) was to increase consumer acceptance of suboptimal food, before and after purchase, by implementing targeted strategies that are based on consumer insights, and that are feasible for and acceptable by the food sector. To reach this aim, different methodological approaches were applied to analyze this issue, to experiment with different aspects, and to test the resulting interventions. Each of these approaches was undertaken by competent consortium partners from Denmark, Germany, Norway, Sweden and The Netherlands. The project finally provides validated strategies to promote the distribution and consumption of suboptimal foods, thereby improving resource efficiency in the food chain and contributing to a more sustainable food supply. PMID- 29186884 TI - Cortisol Awakening Response, Internalizing Symptoms, and Life Satisfaction in Emerging Adults. AB - The cortisol awakening response (CAR) has been associated with depression and a broader range of internalizing problems. Emerging adulthood is characterized by numerous stressful transitional life events. Furthermore, the functioning of the neurobiological stress system changes across development. These considerations underscore the importance of evaluating the physiological stress system in emerging adults in identifying the extent to which cortisol levels vary with risk and protective factors for mental health. The present study evaluated the association between internalizing symptoms and perceived life satisfaction with CAR in 32 young adults. Three saliva samples were collected to measure cortisol levels upon awakening and participants completed the Depression Anxiety Stress Scale (DASS) and Satisfaction with Life Scale (SWLS). Results show a significant positive correlation between area under the curve for CAR with internalizing symptoms (DASS total) and the DASS-depression subscale, but not with life satisfaction. Study limitations, implications, and future directions for these finding were discussed. PMID- 29186885 TI - Plastic Deformation of Pressured Metallic Glass. AB - Although pressured metallic glass (MG) has been reported in the literature; there are few studies focusing on pressure effects on the structure; dynamics and its plastic deformation. In this paper; we report on and characterize; via molecular dynamics simulation, the structure and dynamics heterogeneity of pressured MGs, and explore a causal link between local structures and plastic deformation mechanism of pressured glass. The results exhibit that the dynamical heterogeneity of metallic liquid is more pronounced at high pressure, while the MGs were less fragile after the release of external pressure, reflected by the non-Gaussian parameter (NGP). High pressure glass shows better plastic deformation; and the local strain zone distributed more uniformly than of in normal glass. Further research indicates that although the number of icosahedrons in pressured glass was much larger than that in normal glass, while the interpenetrating connections of icosahedra (ICOI) exhibited spatial correlations were rather poor; In addition, the number of 'fast' atoms indexed by the atoms' moving distance is larger than that in normal glass; leading to the sharp decreasing in number of icosahedrons during deformation. An uniform distribution of 'fast' atoms also contributed to better plastic deformation ability in the pressured glass. These findings may suggest a link between the deformation and destruction of icosahedra with short-range order. PMID- 29186888 TI - Antioxidative Categorization of Twenty Amino Acids Based on Experimental Evaluation. AB - In view of the great importance bestowed on amino acids as antioxidants in oxidation resistance, we attempted two common redox titration methods in this report, including micro-potassium permanganate titration and iodometric titration, to measure the antioxidative capacity of 20 amino acids, which are the construction units of proteins in living organisms. Based on the relative intensities of the antioxidative capacity, we further conducted a quantitative comparison and found out that the product of experimental values obtained from the two methods was proven to be a better indicator for evaluating the relative antioxidative capacity of amino acids. The experimental results were largely in accordance with structural analysis made on amino acids. On the whole, the 20 amino acids concerned could be divided into two categories according to their antioxidative capacity. Seven amino acids, including tryptophan, methionine, histidine, lysine, cysteine, arginine and tyrosine, were greater in total antioxidative capacity compared with the other 13 amino acids. PMID- 29186887 TI - IMU-Based Gait Recognition Using Convolutional Neural Networks and Multi-Sensor Fusion. AB - The wide spread usage of wearable sensors such as in smart watches has provided continuous access to valuable user generated data such as human motion that could be used to identify an individual based on his/her motion patterns such as, gait. Several methods have been suggested to extract various heuristic and high-level features from gait motion data to identify discriminative gait signatures and distinguish the target individual from others. However, the manual and hand crafted feature extraction is error prone and subjective. Furthermore, the motion data collected from inertial sensors have complex structure and the detachment between manual feature extraction module and the predictive learning models might limit the generalization capabilities. In this paper, we propose a novel approach for human gait identification using time-frequency (TF) expansion of human gait cycles in order to capture joint 2 dimensional (2D) spectral and temporal patterns of gait cycles. Then, we design a deep convolutional neural network (DCNN) learning to extract discriminative features from the 2D expanded gait cycles and jointly optimize the identification model and the spectro-temporal features in a discriminative fashion. We collect raw motion data from five inertial sensors placed at the chest, lower-back, right hand wrist, right knee, and right ankle of each human subject synchronously in order to investigate the impact of sensor location on the gait identification performance. We then present two methods for early (input level) and late (decision score level) multi-sensor fusion to improve the gait identification generalization performance. We specifically propose the minimum error score fusion (MESF) method that discriminatively learns the linear fusion weights of individual DCNN scores at the decision level by minimizing the error rate on the training data in an iterative manner. 10 subjects participated in this study and hence, the problem is a 10-class identification task. Based on our experimental results, 91% subject identification accuracy was achieved using the best individual IMU and 2DTF-DCNN. We then investigated our proposed early and late sensor fusion approaches, which improved the gait identification accuracy of the system to 93.36% and 97.06%, respectively. PMID- 29186886 TI - Protein Kinase Targets in Breast Cancer. AB - With 1.67 million new cases and 522,000 deaths in the year 2012, breast cancer is the most common type of diagnosed malignancy and the second leading cause of cancer death in women around the world. Despite the success of screening programs and the development of adjuvant therapies, a significant percentage of breast cancer patients will suffer a metastatic disease that, to this day, remains incurable and justifies the research of new therapies to improve their life expectancy. Among the new therapies that have been developed in recent years, the emergence of targeted therapies has been a milestone in the fight against cancer. Over the past decade, many studies have shown a causal role of protein kinase dysregulations or mutations in different human diseases, including cancer. Along these lines, cancer research has demonstrated a key role of many protein kinases during human tumorigenesis and cancer progression, turning these molecules into valid candidates for new targeted therapies. The subsequent discovery and introduction in 2001 of the kinase inhibitor imatinib, as a targeted treatment for chronic myelogenous leukemia, revolutionized cancer genetic pathways research, and lead to the development of multiple small-molecule kinase inhibitors against various malignancies, including breast cancer. In this review, we analyze studies published to date about novel small-molecule kinase inhibitors and evaluate if they would be useful to develop new treatment strategies for breast cancer patients. PMID- 29186889 TI - A Strategy for Identifying Quantitative Trait Genes Using Gene Expression Analysis and Causal Analysis. AB - Large numbers of quantitative trait loci (QTL) affecting complex diseases and other quantitative traits have been reported in humans and model animals. However, the genetic architecture of these traits remains elusive due to the difficulty in identifying causal quantitative trait genes (QTGs) for common QTL with relatively small phenotypic effects. A traditional strategy based on techniques such as positional cloning does not always enable identification of a single candidate gene for a QTL of interest because it is difficult to narrow down a target genomic interval of the QTL to a very small interval harboring only one gene. A combination of gene expression analysis and statistical causal analysis can greatly reduce the number of candidate genes. This integrated approach provides causal evidence that one of the candidate genes is a putative QTG for the QTL. Using this approach, I have recently succeeded in identifying a single putative QTG for resistance to obesity in mice. Here, I outline the integration approach and discuss its usefulness using my studies as an example. PMID- 29186890 TI - Investigation of Health Effects According to the Exposure of Low Concentration Arsenic Contaminated Ground Water. AB - Recent epidemiological studies have reported adverse health effects, including skin cancer, due to low concentrations of arsenic via drinking water. We conducted a study to assess whether low arsenic contaminated ground water affected health of the residents who consumed it. For precise biomonitoring results, the inorganic (trivalent arsenite (As III) and pentavalent arsenate (As V)) and organic forms (monomethylarsonate (MMA) and dimethylarsinate (DMA)) of arsenic were separately quantified by combining high-performance liquid chromatography and inductively coupled plasma mass spectroscopy from urine samples. In conclusion, urinary As III, As V, MMA, and hair arsenic concentrations were significantly higher in residents who consumed arsenic contaminated ground water than control participants who consumed tap water. But, most health screening results did not show a statistically significant difference between exposed and control subjects. We presume that the elevated arsenic concentrations may not be sufficient to cause detectable health effects. Consumption of arsenic contaminated ground water could result in elevated urinary organic and inorganic arsenic concentrations. We recommend immediate discontinuation of ground water supply in this area for the safety of the residents. PMID- 29186891 TI - Four Novel Zn (II) Coordination Polymers Based on 4'-Ferrocenyl-3,2':6',3'' Terpyridine: Engineering a Switch from 1D Helical Polymer Chain to 2D Network by Coordination Anion Modulation. AB - Four novel ZnII coordination polymers, [(ZnCl2)2(L)2]n (1), [(ZnBr2)2(L)2]n (2), and [(ZnI2)2(L)2]n (3) and {[Zn(SCN)2]1.5(L)3}n (4), have been synthesized based on 4'-ferrocenyl-3,2':6',3''-terpyridine with ZnII ions and different coordination anions under similar ambient conditions. Their structures have been confirmed using single crystal X-ray diffraction analysis, showing that complexes 1-3 are one-dimensional (1D) double-stranded metal ion helical polymer chains and complex 4 is of a two-dimensional (2D) network. The structural transformations of them from a 1D polymer chain to a 2D network under the influence of the coordination anions has been systematic investigated. Furthermore, the optical band gaps have been measured by optical diffuse reflectance spectroscopy, revealing that the ligand and the complexes should have semiconductor properties. PMID- 29186892 TI - Environmental Enrichment for Sucker and Weaner Pigs: The Effect of Enrichment Block Shape on the Behavioural Interaction by Pigs with the Blocks. AB - This experiment tested the effect of enrichment-block shape on oro-nasal contact by young pigs, and possible habituation to the blocks. Nineteen litters (197 piglets) were randomly allocated to one of three block-shape treatments: Cube, Brick, or Wedge. Oro-nasal contact with blocks was infrequent before 25 days of age. Thereafter, contact steadily increased, suggesting enrichment blocks may not need to be provided until week 4 of lactation. Brick-shaped blocks attracted more oro-nasal contact than the cube and wedge shapes (p = 0.002). Oro-nasal contact was more frequent (p < 0.001) during the first 24 h after block introduction than when blocks were four days old. From 25 to 60 days of age, oro-nasal bouts were longer (p = 0.014) during the first 30 min of exposure to a fresh block, than for the remainder of the 24 h, or on day 4 after block replacement. Therefore, habituation to blocks may have occurred by 24 h after block introduction. Brick shaped blocks may present a wider surface for oro-nasal contact, where multiple pigs could simultaneously interact with the block. We speculate that simultaneous interaction with brick-shaped blocks may be similar to a litter co-operatively massaging the sow's udder prior to suckling bouts. PMID- 29186894 TI - One-Step Carbon Coating and Polyacrylamide Functionalization of Fe3O4 Nanoparticles for Enhancing Magnetic Adsorptive-Remediation of Heavy Metals. AB - Magnetic nanoparticles are used in adsorptive removal of heavy metals from polluted wastewater. However, their poor stability in an acidic medium necessitates their protection with a coating layer. Coating magnetic nanoparticles with carbon showed proper protection but the heavy metal removal efficiency was slightly weak. However, to boost the removal efficiencies of surface functionalization, polyacrylamide was applied to carbon-coated Fe3O4 nanoparticles. In this paper, to facilitate the synthesis process, one-step carbon coating and polyacrylamide functionalization were conducted using the hydrothermal technique with the aim of enhancing the adsorptive removal capacity of Fe3O4 nanoparticles towards some heavy metals such as Cu(II), Ni(II), Co(II), and Cd(II). The results showed that the one-step process succeeded in developing a carbon coating layer and polyacrylamide functionality on Fe3O4 nanoparticles. The stability of the magnetic Fe3O4 nanoparticles as an adsorbent in an acidic medium was improved due to its resistance to the dissolution that was gained during carbon coating and surface functionalization with polyacrylamide. The adsorptive removal process was investigated in relation to various parameters such as pH, time of contact, metal ion concentrations, adsorbent dose, and temperature. The polyacrylamide functionalized Fe3O4 showed an improvement in the adsorption capacity as compared with the unfunctionalized one. The conditions for superior adsorption were obtained at pH 6; time of contact, 90 min; metal solution concentration, 200 mg/L; adsorbent dose, 0.3 g/L. The modeling of the adsorption data was found to be consistent with the pseudo-second-order kinetic model, which suggests a fast adsorption process. However, the equilibrium data modeling was consistent with both the Langmuir and Freundlich isotherms. Furthermore, the thermodynamic parameters of the adsorptive removal process, including DeltaG degrees , DeltaH degrees , and DeltaS degrees , indicated a spontaneous and endothermic sorption process. The developed adsorbent can be utilized further for industrial-based applications. PMID- 29186893 TI - Effect of Salt Reduction on Consumer Acceptance and Sensory Quality of Food. AB - Reducing salt (NaCl) intake is an important public health target. The food industry and catering services are searching for means to reduce the salt content in their products. This review focuses on options for salt reduction in foods and the sensory evaluation of salt-reduced foods. Simple salt reduction, mineral salts and flavor enhancers/modifiers (e.g., umami compounds) are common options for salt reduction. In addition, the modification of food texture and odor-taste interactions may contribute to enhanced salty taste perception. Maintaining consumer acceptance of the products is a challenge, and recent examples of the consumer perception of salt-reduced foods are presented. PMID- 29186895 TI - Effects of Adding Clostridium sp. WJ06 on Intestinal Morphology and Microbial Diversity of Growing Pigs Fed with Natural Deoxynivalenol Contaminated Wheat. AB - Deoxynivalenol (DON) is commonly detected in cereals, and is a threat to human and animal health. The effects of microbiological detoxification are now being widely studied. A total of 24 pigs (over four months) were randomly divided into three treatments. Treatment A was fed with a basal diet as the control group. Treatment B was fed with naturally DON-contaminated wheat as a negative control group. Treatment C was fed with a contaminated diet that also had Clostridium sp. WJ06, which was used as a detoxicant. Growth performance, relative organ weight, intestinal morphology, and the intestinal flora of bacteria and fungi were examined. The results showed that after consuming a DON-contaminated diet, the growth performance of the pigs decreased significantly (p < 0.05), the relative organ weight of the liver and kidney increased significantly (p < 0.05), and the integrity of the intestinal barrier was also impaired, though the toxic effects of the contaminated diets on growing pigs were relieved after adding Clostridium sp. WJ06. The data from MiSeq sequencing of the 16S ribosomal ribonucleic acid (rRNA) gene and internal transcribed spacer 1 (ITS1) gene suggested that the abundance of intestinal flora was significantly different across the three treatments. In conclusion, the application of Clostridium sp. WJ06 can reduce the toxic effects of DON and adjust the intestinal microecosystem of growing pigs. PMID- 29186896 TI - The Impact of the Brain-Derived Neurotrophic Factor Gene on Trauma and Spatial Processing. AB - The influence of genes and the environment on the development of Post-Traumatic Stress Disorder (PTSD) continues to motivate neuropsychological research, with one consistent focus being the Brain-Derived Neurotrophic Factor (BDNF) gene, given its impact on the integrity of the hippocampal memory system. Research into human navigation also considers the BDNF gene in relation to hippocampal dependent spatial processing. This speculative paper brings together trauma and spatial processing for the first time and presents exploratory research into their interactions with BDNF. We propose that quantifying the impact of BDNF on trauma and spatial processing is critical and may well explain individual differences in clinical trauma treatment outcomes and in navigation performance. Research has already shown that the BDNF gene influences PTSD severity and prevalence as well as navigation behaviour. However, more data are required to demonstrate the precise hippocampal dependent processing mechanisms behind these influences in different populations and environmental conditions. This paper provides insight from recent studies and calls for further research into the relationship between allocentric processing, trauma processing and BDNF. We argue that research into these neural mechanisms could transform PTSD clinical practice and professional support for individuals in trauma-exposing occupations such as emergency response, law enforcement and the military. PMID- 29186897 TI - Non-Coding RNAs in Pediatric Airway Diseases. AB - Non-coding RNAs (ncRNAs) are involved in the regulation of numerous biological processes and pathways and therefore have been extensively studied in human diseases. Previous reports have shown that non-coding RNAs play a crucial role in the pathogenesis and aberrant regulation of respiratory diseases. The altered expression of microRNAs (miRNAs) and long noncoding RNAs in blood and also locally in sputum or exhaled breath condensate influences lung function, immune response, and disease phenotype and may be used for the development of biomarkers specific for airway disease. In this review, we provide an overview of the recent works studying the non-coding RNAs in airway diseases, with a particular focus on chronic respiratory diseases of childhood. We have chosen the most common chronic respiratory condition-asthma- and the most severe, chronic disease of the airways cystic fibrosis. Study of the altered expression of non-coding RNAs in these diseases may be key to better understanding their pathogenesis and improving diagnosis, while also holding promise for the development of therapeutic strategies using the regulatory potential of non-coding RNAs. PMID- 29186899 TI - Obstacles to Brain Tumor Therapy: Key ABC Transporters. AB - The delivery of cancer chemotherapy to treat brain tumors remains a challenge, in part, because of the inherent biological barrier, the blood-brain barrier. While its presence and role as a protector of the normal brain parenchyma has been acknowledged for decades, it is only recently that the important transporter components, expressed in the tightly knit capillary endothelial cells, have been deciphered. These transporters are ATP-binding cassette (ABC) transporters and, so far, the major clinically important ones that functionally contribute to the blood-brain barrier are ABCG2 and ABCB1. A further limitation to cancer therapy of brain tumors or brain metastases is the blood-tumor barrier, where tumors erect a barrier of transporters that further impede drug entry. The expression and regulation of these two transporters at these barriers, as well as tumor derived alteration in expression and/or mutation, are likely obstacles to effective therapy. PMID- 29186898 TI - Thermodynamic Aspects and Reprogramming Cellular Energy Metabolism during the Fibrosis Process. AB - Fibrosis is characterized by fibroblast proliferation and fibroblast differentiation into myofibroblasts, which generate a relaxation-free contraction mechanism associated with excessive collagen synthesis in the extracellular matrix, which promotes irreversible tissue retraction evolving towards fibrosis. From a thermodynamic point of view, the mechanisms leading to fibrosis are irreversible processes that can occur through changing the entropy production rate. The thermodynamic behaviors of metabolic enzymes involved in fibrosis are modified by the dysregulation of both transforming growth factor beta (TGF-beta) signaling and the canonical WNT/beta-catenin pathway, leading to aerobic glycolysis, called the Warburg effect. Molecular signaling pathways leading to fibrosis are considered dissipative structures that exchange energy or matter with their environment far from the thermodynamic equilibrium. The myofibroblastic cells arise from exergonic processes by switching the core metabolism from oxidative phosphorylation to glycolysis, which generates energy and reprograms cellular energy metabolism to induce the process of myofibroblast differentiation. Circadian rhythms are far-from-equilibrium thermodynamic processes. They directly participate in regulating the TGF-beta and WNT/beta catenin pathways involved in energetic dysregulation and enabling fibrosis. The present review focusses on the thermodynamic implications of the reprogramming of cellular energy metabolism, leading to fibroblast differentiation into myofibroblasts through the positive interplay between TGF-beta and WNT/beta catenin pathways underlying in fibrosis. PMID- 29186901 TI - Live Fluorescent Staining Platform for Drug-Screening and Mechanism-Analysis in Zebrafish for Bone Mineralization. AB - Currently, drug screening relies on cell-based experiments or on animal models to confirm biological effects. The mammalian system is considered too time consuming, expensive and complex to perform high-throughput drug screening. There is a gap between in vitro cell-based models and the in vivo mammalian models. The zebrafish is an ideal model that could link preclinical toxicity screening with the drug development pipeline. Taking advantage of a highly conservative genomic, rapid development, large number of offspring, low cost and easy manipulation, zebrafish has been considered an excellent animal model for disease-based drug screening. In this study, zebrafish embryos were incubated with small molecular compounds that potentially affected bone mineralization in microplates. Two compounds of alendronate and dorsomorphin were used as positive and negative controls, respectively. The level of osteogenic mineralization was measured and quantified by using ImageJ software with fluorescent calcein-staining images. Among twenty-four tested compounds from the kinase inhibitor library, we identified two compounds, pentamidine and BML-267, which showed increased embryonic mineralization; while six compounds, RWJ-60475, levamisole HCL, tetramisole HCL, fenvalerate, NSC-663284, and BML-267ester, were inhibitory to bone mineralization. In addition, real time quantitative PCR (RT-qPCR) was performed to evaluate the biological pathways involved in bone metabolism at the molecular level. We confirmed that alendronate enhanced the level of bone mineralization by inhibiting osteoclast-related genes. In summary, our research established a simple method to screen potential bone metabolic drugs and to perform mechanism analysis for bone mineralization in vivo. PMID- 29186902 TI - Annotation of Peptide Structures Using SMILES and Other Chemical Codes-Practical Solutions. AB - Contemporary peptide science exploits methods and tools of bioinformatics, and cheminformatics. These approaches use different languages to describe peptide structures-amino acid sequences and chemical codes (especially SMILES), respectively. The latter may be applied, e.g., in comparative studies involving structures and properties of peptides and peptidomimetics. Progress in peptide science "in silico" may be achieved via better communication between biologists and chemists, involving the translation of peptide representation from amino acid sequence into SMILES code. Recent recommendations concerning good practice in chemical information include careful verification of data and their annotation. This publication discusses the generation of SMILES representations of peptides using existing software. Construction of peptide structures containing unnatural and modified amino acids (with special attention paid on glycosylated peptides) is also included. Special attention is paid to the detection and correction of typical errors occurring in SMILES representations of peptides and their correction using molecular editors. Brief recommendations for training of staff working on peptide annotations, are discussed as well. PMID- 29186903 TI - Bacteriological and Immunological Profiling of Meconium and Fecal Samples from Preterm Infants: A Two-Year Follow-Up Study. AB - An abnormal colonization pattern of the preterm gut may affect immune maturation and exert a long-term influence on the intestinal bacterial composition and host health. However, follow-up studies assessing the evolution of the fecal microbiota of infants that were born preterm are very scarce. In this work, the bacterial compositions of fecal samples, obtained from sixteen 2-year-old infants were evaluated using a phylogenetic microarray; subsequently, the results were compared with those obtained in a previous study from samples of meconium and feces collected from the same infants while they stayed in the neonatal intensive care unit (NICU). In parallel, the concentration of a wide range of cytokines, chemokines, growth factors and immunoglobulins were determined in meconium and fecal samples. Globally, a higher bacterial diversity and a lower interindividual variability were observed in 2-year-olds' feces, when compared to the samples obtained during their first days of life. Hospital-associated fecal bacteria, that were dominant during the NICU stay, seemed to be replaced, two years later, by genera, which are usually predominant in the healthy adult microbiome. The immune profile of the meconium and fecal samples differed, depending on the sampling time, showing different immune maturation statuses of the gut. PMID- 29186900 TI - Rodent Papillomaviruses. AB - Preclinical infection model systems are extremely valuable tools to aid in our understanding of Human Papillomavirus (HPV) biology, disease progression, prevention, and treatments. In this context, rodent papillomaviruses and their respective infection models are useful tools but remain underutilized resources in the field of papillomavirus biology. Two rodent papillomaviruses, MnPV1, which infects the Mastomys species of multimammate rats, and MmuPV1, which infects laboratory mice, are currently the most studied rodent PVs. Both of these viruses cause malignancy in the skin and can provide attractive infection models to study the lesser understood cutaneous papillomaviruses that have been frequently associated with HPV-related skin cancers. Of these, MmuPV1 is the first reported rodent papillomavirus that can naturally infect the laboratory strain of mice. MmuPV1 is an attractive model virus to study papillomavirus pathogenesis because of the ubiquitous availability of lab mice and the fact that this mouse species is genetically modifiable. In this review, we have summarized the knowledge we have gained about PV biology from the study of rodent papillomaviruses and point out the remaining gaps that can provide new research opportunities. PMID- 29186904 TI - The Roles of microRNAs in Regulating the Expression of PD-1/PD-L1 Immune Checkpoint. AB - Engagement of programmed death-ligand 1 (PD-L1) with its receptor programmed death 1 (PD-1) on T cells has been speculated to play a major role in suppressing the immune system, which helps tumor cells evade anti-tumor immunity. With the development of whole genome sequencing technologies, microRNAs have gained more attention as an important new layer of molecular regulation. Recent studies have revealed that altered expression of microRNAs play a pivotal role in immune checkpoint and various cellular processes in cancer. In this review, we focused on the latest progress about microRNAs research which involves the regulation of PD-1/PD-L1 immune checkpoint. PMID- 29186905 TI - Development of Cell-Specific Aptamers: Recent Advances and Insight into the Selection Procedures. AB - Systematic evolution of ligands by exponential enrichment (SELEX) is an established procedure for developing short single-stranded nucleic acid ligands called aptamers against a target of choice. This approach has also been used for developing aptamers specific to whole cells named Cell-SELEX. Aptamers selected by Cell-SELEX have the potential to act as cell specific therapeutics, cell specific markers or cell specific drug delivery and imaging agents. However, aptamer development is a laborious and time-consuming process which is often challenging due to the requirement of frequent optimization of various steps involved in Cell-SELEX procedures. This review provides an insight into various procedures for selection, aptamer enrichment, regeneration and aptamer-binding analysis, in addition to a very recent update on all aptamers selected by Cell SELEX procedures. PMID- 29186906 TI - Design, Synthesis and Bioactivities of Novel Isoxazole-Containing Pyrazole Oxime Derivatives. AB - In this study, in order to find novel biologically active pyrazole oxime derivatives, twenty-eight new pyrazole oxime compounds containing a substituted isoxazole ring were synthesized and evaluated for their acaricidaland insecticidal activities. Bioassays exhibited that some target compounds indicated good acaricidal and insecticidal activities against Tetranychus cinnabarinus, Aphis medicaginis, Mythimna separata, and Nilaparvata lugens. Especially, compounds 9c, 9h, 9u, and 9v showed 100.00%, 90.56%, 90.78%, and 90.62% insecticidal activities against A. medicaginis at the concentration of 20 MUg/mL, respectively, compounds 9k and 9u had 70.86% and 100.00% insecticidal activities against M. separata at 20 MUg/mL, respectively. PMID- 29186907 TI - Effect of Clinically Relevant CAD/CAM Zirconia Polishing on Gingival Fibroblast Proliferation and Focal Adhesions. AB - Mucosal seal formation around dental abutments is critical to the successful integration of dental implants into the human oral cavity. No information exists for how clinically relevant polishing procedures for computer-aided design and computer-aided manufactured (CAD/CAM) zirconia abutments affects cellular responses important to mucosal seal formation. CAD/CAM zirconia was divided into four groups for clinically relevant polishing utilizing commercial polishing heads: control, coarse, coarse plus medium, and coarse plus medium plus fine. Surfaces were analyzed with scanning electron microscopy (SEM), atomic force microscopy (AFM), and optical profilometry (OP). Subsequently, human gingival fibroblasts (HGFs) were seeded onto the zirconia surfaces. Proliferation was measured via a quantitative SEM technique and focal adhesion kinase (FAK) phosphorylation status was measured by an enzyme-linked immunosorbent assay (ELISA). Results showed an increase in proliferation on all polished surfaces as compared to the control. Phosphorylation of FAK at tyrosine 397 (Y397) was up modulated on the control surfaces. The associated cell adaptation is discussed. In all cases, FAK phosphorylation was greater at 24 h than 48 h. These results suggest that clinicians should be mindful of the effects of abutment polishing methodology, as this may have an impact on early mucosal seal formation. PMID- 29186908 TI - The Effect of a Diet Moderately High in Protein and Fiber on Insulin Sensitivity Measured Using the Dynamic Insulin Sensitivity and Secretion Test (DISST). AB - Evidence shows that weight loss improves insulin sensitivity but few studies have examined the effect of macronutrient composition independently of weight loss on direct measures of insulin sensitivity. We randomised 89 overweight or obese women to either a standard diet (StdD), that was intended to be low in fat and relatively high in carbohydrate (n = 42) or to a relatively high protein (up to 30% of energy), relatively high fibre (>30 g/day) diet (HPHFib) (n = 47) for 10 weeks. Advice regarding strict adherence to energy intake goals was not given. Insulin sensitivity and secretion was assessed by a novel method-the Dynamic Insulin Sensitivity and Secretion Test (DISST). Although there were significant improvements in body composition and most cardiometabolic risk factors on HPHFib, insulin sensitivity was reduced by 19.3% (95% CI: 31.8%, 4.5%; p = 0.013) in comparison with StdD. We conclude that the reduction in insulin sensitivity after a diet relatively high in both protein and fibre, despite cardiometabolic improvements, suggests insulin sensitivity may reflect metabolic adaptations to dietary composition for maintenance of glucose homeostasis, rather than impaired metabolism. PMID- 29186910 TI - Mn-Doped CaBi4Ti4O15/Pb(Zr,Ti)O3 Ultrasonic Transducers for Continuous Monitoring at Elevated Temperatures. AB - Continuous ultrasonic in-situ monitoring for industrial applications is difficult owing to the high operating temperatures in industrial fields. It is expected that ultrasonic transducers consisting of a CaBi4Ti4O15(CBT)/Pb(Zr,Ti)O3(PZT) sol gel composite could be one solution for ultrasonic nondestructive testing (NDT) above 500 degrees C because no couplant is required and CBT has a high Curie temperature. To verify the high temperature durability, CBT/PZT sol-gel composite films were fabricated on titanium substrates by spray coating, and the CBT/PZT samples were tested in a furnace at various temperatures. Reflected echoes with a high signal-to-noise ratio were observed up to 600 degrees C. A thermal cycle test was conducted from room temperature to 600 degrees C, and no significant deterioration was found after the second thermal cycle. To investigate the long term high-temperature durability, a CBT/PZT ultrasonic transducer was tested in the furnace at 600 degrees C for 36 h. Ultrasonic responses were recorded every 3 h, and the sensitivity and signal-to-noise ratio were stable throughout the experiment. PMID- 29186909 TI - Ketamine, a Clinically Used Anesthetic, Inhibits Vascular Smooth Muscle Cell Proliferation via PP2A-Activated PI3K/Akt/ERK Inhibition. AB - Abnormal proliferation of vascular smooth muscle cells (VSMCs) gives rise to major pathological processes involved in the development of cardiovascular diseases. The use of anti-proliferative agents for VSMCs offers potential for the treatment of vascular disorders. Intravenous anesthetics are firmly established to have direct effects on VSMCs, resulting in modulation of blood pressure. Ketamine has been used for many years in the intensive care unit (ICU) for sedation, and has recently been considered for adjunctive therapy. In the present study, we investigated the effects of ketamine on platelet-derived growth factor BB (PDGF-BB)-induced VSMC proliferation and the associated mechanism. Ketamine concentration-dependently inhibited PDGF-BB-induced VSMC proliferation without cytotoxicity, and phosphatidylinositol 3-kinase (PI3K) and extracellular signal regulated protein kinase (ERK) inhibitors, LY294002 and PD98059, respectively, have similar inhibitory effects. Ketamine was shown to attenuate PI3K, Akt, and ERK1/2 phosphorylation induced by PDGF-BB. Okadaic acid, a selective protein phosphatase 2A (PP2A) inhibitor, significantly reversed ketamine-mediated PDGF-BB induced PI3K, Akt, and ERK1/2 phosphorylation; a transfected protein phosphatse 2a (pp2a) siRNA reversed Akt and ERK1/2 phosphorylation; and 3-O-Methyl sphingomyeline (3-OME), an inhibitor of sphingomyelinase, also significantly reversed ERK1/2 phosphorylation. Moreover, ketamine alone significantly inhibited tyrosine phosphorylation and demethylation of PP2A in a concentration-dependent manner. In addition, the pp2a siRNA potently reversed the ketamine-activated catalytic subunit (PP2A-C) of PP2A. These results provide evidence of an anti proliferating effect of ketamine in VSMCs, showing activation of PP2A blocks PI3K, Akt, and ERK phosphorylation that subsequently inhibits the proliferation of VSMCs. Thus, ketamine may be considered a potential effective therapeutic agent for reducing atherosclerotic process by blocking the proliferation of VSMCs. PMID- 29186911 TI - Prostaglandin E2 in the Regulation of Water Transport in Renal Collecting Ducts. AB - The kidney plays a central role in the regulation of the body water balance. The process of targeting the water channel aquaporin-2 (AQP2) on the apical plasma membrane of the collecting duct (CD) principal cells is mainly regulated by the antidiuretic peptide hormone arginine vasopressin (AVP), which is responsible for the maintenance of water homeostasis. Recently, much attention has been focused on the local factors modulating renal water reabsorption by AQP2 in the collecting ducts, especially prostaglandin E2 (PGE2). PGE2 is a lipid mediator involved in a variety of physiological and pathophysiological processes in the kidney. The biological function of PGE2 is mainly mediated by four G-protein coupled receptors, namely EP1-4, which couple to drive separate intracellular signaling pathways. Increasing evidence demonstrates that PGE2 is essential for renal water transport regulation via multiple mechanisms. Each EP receptor plays a unique role in regulating water reabsorption in renal collecting ducts. This brief review highlights the role of PGE2 in the regulation of water reabsorption and discusses the involvement of each EP receptor subtype in renal collecting duct. A better understanding of the role of PGE2 in renal water transport process may improve disease management strategies for water balance disorders, including nephrogenic diabetes insipidus. PMID- 29186913 TI - Colorectal Cancer and Colitis Diagnosis Using Fourier Transform Infrared Spectroscopy and an Improved K-Nearest-Neighbour Classifier. AB - Combining Fourier transform infrared spectroscopy (FTIR) with endoscopy, it is expected that noninvasive, rapid detection of colorectal cancer can be performed in vivo in the future. In this study, Fourier transform infrared spectra were collected from 88 endoscopic biopsy colorectal tissue samples (41 colitis and 47 cancers). A new method, viz., entropy weight local-hyperplane k-nearest-neighbor (EWHK), which is an improved version of K-local hyperplane distance nearest neighbor (HKNN), is proposed for tissue classification. In order to avoid limiting high dimensions and small values of the nearest neighbor, the new EWHK method calculates feature weights based on information entropy. The average results of the random classification showed that the EWHK classifier for differentiating cancer from colitis samples produced a sensitivity of 81.38% and a specificity of 92.69%. PMID- 29186912 TI - Computer-Aided Drug Design Applied to Marine Drug Discovery: Meridianins as Alzheimer's Disease Therapeutic Agents. AB - Computer-aided drug discovery/design (CADD) techniques allow the identification of natural products that are capable of modulating protein functions in pathogenesis-related pathways, constituting one of the most promising lines followed in drug discovery. In this paper, we computationally evaluated and reported the inhibitory activity found in meridianins A-G, a group of marine indole alkaloids isolated from the marine tunicate Aplidium, against various protein kinases involved in Alzheimer's disease (AD), a neurodegenerative pathology characterized by the presence of neurofibrillary tangles (NFT). Balance splitting between tau kinase and phosphate activities caused tau hyperphosphorylation and, thereby, its aggregation and NTF formation. Inhibition of specific kinases involved in its phosphorylation pathway could be one of the key strategies to reverse tau hyperphosphorylation and would represent an approach to develop drugs to palliate AD symptoms. Meridianins bind to the adenosine triphosphate (ATP) binding site of certain protein kinases, acting as ATP competitive inhibitors. These compounds show very promising scaffolds to design new drugs against AD, which could act over tau protein kinases Glycogen synthetase kinase-3 Beta (GSK3beta) and Casein kinase 1 delta (CK1delta, CK1D or KC1D), and dual specificity kinases as dual specificity tyrosine phosphorylation regulated kinase 1 (DYRK1A) and cdc2-like kinases (CLK1). This work is aimed to highlight the role of CADD techniques in marine drug discovery and to provide precise information regarding the binding mode and strength of meridianins against several protein kinases that could help in the future development of anti AD drugs. PMID- 29186914 TI - The Contribution of New Areas to the Total Hirsutism Scores in Basrah Hirsute Women. AB - BACKGROUND: Hirsutism is the presence of excessive growth of terminal hair in a female in the male-like pattern. It is the most common indicator of hyperandrogenism. The primary objective of this study was to evaluate the clinical impact of new androgens sensitive skin area to total body hirsutism score. METHODS: This was cross-sectional study. Most of the patients in this study group (n = 300) were women of reproductive age group (20-39 years) with a mean age of 26.6 +/- 7.1 years. They were recruited in Faiha Specialized Diabetes, Endocrine, and Metabolism Center (FDEMC) during the period from August 2016 to the end of August 2017. All complained from hirsutism and were assessed by using modified Ferriman-Gallwey (m-FG) score system by a single examiner. Each patient underwent detailed clinical assessment in addition to transabdominal or transvaginal ultrasonography of the pelvis with endocrinological investigations. RESULTS: Comparison of the mean score at different body areas revealed that new androgens sensitive skin areas (sideburn, lower jaw/neck, buttocks/perineum) were comparable to others area of original m-FG score system or higher than at least three area used in the score. The sideburn area was observed to have the highest score among the new androgens sensitive skin areas. CONCLUSION: Evaluating the terminal hair growth in the new three androgen-sensitive skin areas (sideburn, lower jaw/neck, and buttocks/perineum) were clinically useful in assessing hirsutism score with high impact on total score. PMID- 29186915 TI - Development of a Dog-Assisted Activity Program in an Elementary Classroom. AB - Here we describe a pilot Dog-Assisted Activity program that was designed to improve wellbeing and social integration in a multi-cultural elementary classroom in which some episodes of bullying had been reported. We developed a 5-encounters protocol with the aim of introducing pet dogs into the class to stimulate understanding of different types of communication and behavior, ultimately facilitating positive relationships among peers. A preliminary evaluation was carried out in order to assess the effect of the program on teachers' perception of children's difficulties (e.g., peer relationship problems) and strengths (prosocial behaviors) by means of a brief behavioral screening tool, the Strengths and Difficulties Questionnaire (SDQ-Teacher version). Overall results indicate that, by means of the recognition of the dogs' behavior and non-verbal communication, children were able to express their emotions and to show behaviors that had not been recognized by the teachers prior to the intervention. In particular, the SDQ Total Difficulties scores suggest that the teacher had increased awareness of the students' difficulties as a result of the dog-assisted program. Overall, the presence of animals in the educational environment may provide enjoyment and hands-on educational experiences, enhanced psychological wellbeing, and increased empathy and socio-emotional development. PMID- 29186917 TI - The Design and Evaluation of an l-Dopa-Lazabemide Prodrug for the Treatment of Parkinson's Disease. AB - l-Dopa, the metabolic precursor of dopamine, is the treatment of choice for the symptomatic relief of the advanced stages of Parkinson's disease. The oral bioavailability of l-dopa, however, is only about 10% to 30%, and less than 1% of the oral dose is estimated to reach the brain unchanged. l-Dopa's physicochemical properties are responsible for its poor bioavailability, short half-life and the wide range of inter- and intrapatient variations of plasma levels. An l-dopa lazabemide prodrug is proposed to overcome the problems associated with l-dopa absorption. Lazabemide is a monoamine oxidase (MAO)-B inhibitor, a class of compounds that slows the depletion of dopamine stores in Parkinson's disease and elevates dopamine levels produced by exogenously administered l-dopa. l-Dopa was linked at the carboxylate with the primary aminyl functional group of lazabemide via an amide, a strategy which is anticipated to protect l-dopa against peripheral decarboxylation and possibly also enhance the membrane permeability of the prodrug. Selected physicochemical and biochemical properties of the prodrug were determined and included lipophilicity (logD), solubility, passive diffusion permeability, pKa, chemical and metabolic stability as well as cytotoxicity. Although oral and i.p. treatment of mice with the prodrug did not result in enhanced striatal dopamine levels, 3,4-dihydroxyphenylacetic acid (DOPAC) levels were significantly depressed compared to saline, l-dopa and carbidopa/l-dopa treatment. Based on the results, further preclinical evaluation of the l-dopa lazabemide prodrug should be undertaken with the aim of discovering prodrugs that may be advanced to the clinical stages of development. PMID- 29186916 TI - Ecology and Evolution in the RNA World Dynamics and Stability of Prebiotic Replicator Systems. AB - As of today, the most credible scientific paradigm pertaining to the origin of life on Earth is undoubtedly the RNA World scenario. It is built on the assumption that catalytically active replicators (most probably RNA-like macromolecules) may have been responsible for booting up life almost four billion years ago. The many different incarnations of nucleotide sequence (string) replicator models proposed recently are all attempts to explain on this basis how the genetic information transfer and the functional diversity of prebiotic replicator systems may have emerged, persisted and evolved into the first living cell. We have postulated three necessary conditions for an RNA World model system to be a dynamically feasible representation of prebiotic chemical evolution: (1) it must maintain and transfer a sufficient diversity of information reliably and indefinitely, (2) it must be ecologically stable and (3) it must be evolutionarily stable. In this review, we discuss the best-known prebiotic scenarios and the corresponding models of string-replicator dynamics and assess them against these criteria. We suggest that the most popular of prebiotic replicator systems, the hypercycle, is probably the worst performer in almost all of these respects, whereas a few other model concepts (parabolic replicator, open chaotic flows, stochastic corrector, metabolically coupled replicator system) are promising candidates for development into coherent models that may become experimentally accessible in the future. PMID- 29186918 TI - Depressive Symptom and Related Factors: A Cross-Sectional Study of Korean Female Workers Working at Traditional Markets. AB - BACKGROUND: Depression is one of the psychiatric diseases with a high prevalence rate, globally, and reportedly more prevalent among women than among men. Especially, women workers working at traditional markets are in depressive conditions without occupational health services. The purpose of this study is to investigate factors having a significant effect on the depressive symptoms of women workers at traditional markets in South Korea. METHODS: A cross-sectional study was used and subjects for the present study were 500 female workers in three selected representative traditional marketplaces in South Korea. RESULTS: The results of hierarchical regression analysis indicated that increased BMI (beta = 0.297, p = 0.017), poor nutritional status (beta = 0.596, p < 0.001), street vendor status (beta = 2.589, p = 0.001), job stress (beta = 0.491, p < 0.001), lower back pain (beta = 0.377, p = 0.011), lower self-efficacy (beta = 0.368, p = 0.002) and diminished family function (beta = -0.633, p = 0.001) affected workers' depressive symptoms. The explanatory power of these variables was 38.5%. CONCLUSIONS: Based on these results, future research should focus on incorporating theses significant factors into effective interventions designed to decrease depressive symptoms in this population. Moreover, this study will increase interest in occupational health nursing, particularly in relation to vulnerable social groups, and expand the scope of practice in the field. PMID- 29186919 TI - A Strategic Bargaining Game for a Spectrum Sharing Scheme in Cognitive Radio Based Heterogeneous Wireless Sensor Networks. AB - In Wireless Sensor Networks (WSNs), unlicensed users, that is, sensor nodes, have excessively exploited the unlicensed radio spectrum. Through Cognitive Radio (CR), licensed radio spectra, which are owned by licensed users, can be partly or entirely shared with unlicensed users. This paper proposes a strategic bargaining spectrum-sharing scheme, considering a CR-based heterogeneous WSN (HWSN). The sensors of HWSNs are discrepant and exist in different wireless environments, which leads to various signal-to-noise ratios (SNRs) for the same or different licensed users. Unlicensed users bargain with licensed users regarding the spectrum price. In each round of bargaining, licensed users are allowed to adaptively adjust their spectrum price to the best for maximizing their profits. . Then, each unlicensed user makes their best response and informs licensed users of "bargaining" and "warning". Through finite rounds of bargaining, this scheme can obtain a Nash bargaining solution (NBS), which makes all licensed and unlicensed users reach an agreement. The simulation results demonstrate that the proposed scheme can quickly find a NBS and all players in the game prefer to be honest. The proposed scheme outperforms existing schemes, within a certain range, in terms of fairness and trade success probability. PMID- 29186921 TI - Analysis of Sources of Large Positioning Errors in Deterministic Fingerprinting. AB - Wi-Fi fingerprinting is widely used for indoor positioning and indoor navigation due to the ubiquity of wireless networks, high proliferation of Wi-Fi-enabled mobile devices, and its reasonable positioning accuracy. The assumption is that the position can be estimated based on the received signal strength intensity from multiple wireless access points at a given point. The positioning accuracy, within a few meters, enables the use of Wi-Fi fingerprinting in many different applications. However, it has been detected that the positioning error might be very large in a few cases, which might prevent its use in applications with high accuracy positioning requirements. Hybrid methods are the new trend in indoor positioning since they benefit from multiple diverse technologies (Wi-Fi, Bluetooth, and Inertial Sensors, among many others) and, therefore, they can provide a more robust positioning accuracy. In order to have an optimal combination of technologies, it is crucial to identify when large errors occur and prevent the use of extremely bad positioning estimations in hybrid algorithms. This paper investigates why large positioning errors occur in Wi-Fi fingerprinting and how to detect them by using the received signal strength intensities. PMID- 29186920 TI - RNA Chaperone Function of a Universal Stress Protein in Arabidopsis Confers Enhanced Cold Stress Tolerance in Plants. AB - The physiological function of Arabidopsis thaliana universal stress protein (AtUSP) in plant has remained unclear. Thus, we report here the functional role of the Arabidopsis universal stress protein, AtUSP (At3g53990). To determine how AtUSP affects physiological responses towards cold stress, AtUSP overexpression (AtUSP OE) and T-DNA insertion knock-out (atusp, SALK_146059) mutant lines were used. The results indicated that AtUSP OE enhanced plant tolerance to cold stress, whereas atusp did not. AtUSP is localized in the nucleus and cytoplasm, and cold stress significantly affects RNA metabolism such as by misfolding and secondary structure changes of RNA. Therefore, we investigated the relationship of AtUSP with RNA metabolism. We found that AtUSP can bind nucleic acids, including single- and double-stranded DNA and luciferase mRNA. AtUSP also displayed strong nucleic acid-melting activity. We expressed AtUSP in RL211 Escherichia coli, which contains a hairpin-loop RNA structure upstream of chloramphenicol acetyltransferase (CAT), and observed that AtUSP exhibited anti termination activity that enabled CAT gene expression. AtUSP expression in the cold-sensitive Escherichia coli (E. coli) mutant BX04 complemented the cold sensitivity of the mutant cells. As these properties are typical characteristics of RNA chaperones, we conclude that AtUSP functions as a RNA chaperone under cold shock conditions. Thus, the enhanced tolerance of AtUSP OE lines to cold stress is mediated by the RNA chaperone function of AtUSP. PMID- 29186922 TI - An Overview of GIS-Based Modeling and Assessment of Mining-Induced Hazards: Soil, Water, and Forest. AB - In this study, current geographic information system (GIS)-based methods and their application for the modeling and assessment of mining-induced hazards were reviewed. Various types of mining-induced hazard, including soil contamination, soil erosion, water pollution, and deforestation were considered in the discussion of the strength and role of GIS as a viable problem-solving tool in relation to mining-induced hazards. The various types of mining-induced hazard were classified into two or three subtopics according to the steps involved in the reclamation procedure, or elements of the hazard of interest. Because GIS is appropriated for the handling of geospatial data in relation to mining-induced hazards, the application and feasibility of exploiting GIS-based modeling and assessment of mining-induced hazards within the mining industry could be expanded further. PMID- 29186923 TI - Adapting Local Features for Face Detection in Thermal Image. AB - A thermal camera captures the temperature distribution of a scene as a thermal image. In thermal images, facial appearances of different people under different lighting conditions are similar. This is because facial temperature distribution is generally constant and not affected by lighting condition. This similarity in face appearances is advantageous for face detection. To detect faces in thermal images, cascade classifiers with Haar-like features are generally used. However, there are few studies exploring the local features for face detection in thermal images. In this paper, we introduce two approaches relying on local features for face detection in thermal images. First, we create new feature types by extending Multi-Block LBP. We consider a margin around the reference and the generally constant distribution of facial temperature. In this way, we make the features more robust to image noise and more effective for face detection in thermal images. Second, we propose an AdaBoost-based training method to get cascade classifiers with multiple types of local features. These feature types have different advantages. In this way we enhance the description power of local features. We did a hold-out validation experiment and a field experiment. In the hold-out validation experiment, we captured a dataset from 20 participants, comprising 14 males and 6 females. For each participant, we captured 420 images with 10 variations in camera distance, 21 poses, and 2 appearances (participant with/without glasses). We compared the performance of cascade classifiers trained by different sets of the features. The experiment results showed that the proposed approaches effectively improve the performance of face detection in thermal images. In the field experiment, we compared the face detection performance in realistic scenes using thermal and RGB images, and gave discussion based on the results. PMID- 29186925 TI - Indigenous Values and Health Systems Stewardship in Circumpolar Countries. AB - Circumpolar regions, and the nations within which they reside, have recently gained international attention because of shared and pressing public policy issues such as climate change, resource development, endangered wildlife and sovereignty disputes. In a call for national and circumpolar action on shared areas of concern, the Arctic states health ministers recently met and signed a declaration that identified shared priorities for international cooperation. Among the areas for collaboration raised, the declaration highlighted the importance of enhancing intercultural understanding, promoting culturally appropriate health care delivery and strengthening circumpolar collaboration in culturally appropriate health care delivery. This paper responds to the opportunity for further study to fully understand indigenous values and contexts, and presents these as they may apply to a framework that will support international comparisons and systems improvements within circumpolar regions. We explored the value base of indigenous peoples and provide considerations on how these values might interface with national values, health systems values and value bases between indigenous nations particularly in the context of health system policy-making that is inevitably shared between indigenous communities and jurisdictional or federal governments. Through a mixed methods nominal consensus process, nine values were identified and described: humanity, cultural responsiveness, teaching, nourishment, community voice, kinship, respect, holism and empowerment. PMID- 29186924 TI - Regulation of the Tumor-Suppressor BECLIN 1 by Distinct Ubiquitination Cascades. AB - Autophagy contributes to cellular homeostasis through the degradation of various intracellular targets such as proteins, organelles and microbes. This relates autophagy to various diseases such as infections, neurodegenerative diseases and cancer. A central component of the autophagy machinery is the class III phosphatidylinositol 3-kinase (PI3K-III) complex, which generates the signaling lipid phosphatidylinositol 3-phosphate (PtdIns3P). The catalytic subunit of this complex is the lipid-kinase VPS34, which associates with the membrane-targeting factor VPS15 as well as the multivalent adaptor protein BECLIN 1. A growing list of regulatory proteins binds to BECLIN 1 and modulates the activity of the PI3K III complex. Here we discuss the regulation of BECLIN 1 by several different types of ubiquitination, resulting in distinct polyubiquitin chain linkages catalyzed by a set of E3 ligases. This contribution is part of the Special Issue "Ubiquitin System". PMID- 29186927 TI - Estimating Free and Added Sugar Intakes in New Zealand. AB - The reduction of free or added sugar intake (sugars added to food and drinks as a sweetener) is almost universally recommended to reduce the risk of obesity related diseases and dental caries. The World Health Organisation recommends intakes of free sugars of less than 10% of energy intake. However, estimating and monitoring intakes at the population level is challenging because free sugars cannot be analytically distinguished from naturally occurring sugars and most national food composition databases do not include data on free or added sugars. We developed free and added sugar estimates for the New Zealand (NZ) food composition database (FOODfiles 2010) by adapting a method developed for Australia. We reanalyzed the 24 h recall dietary data collected for 4721 adults aged 15 years and over participating in the nationally representative 2008/09 New Zealand Adult Nutrition Survey to estimate free and added sugar intakes. The median estimated intake of free and added sugars was 57 and 49 g/day respectively and 42% of adults consumed less than 10% of their energy intake from free sugars. This approach provides more direct estimates of the free and added sugar contents of New Zealand foods than previously available and will enable monitoring of adherence to free sugar intake guidelines in future.

AB - The fermentation and isolation of metabolites produced by an endophytic fungus, which was identified as Phomopsis sp. FJBR-11, based on phylogenetic analysis, led to the identification of six compounds, including dothiorelones A-C, and H, and cytosporones C and U. Among these compounds, cytosporone U exhibited potent inhibitory activity against Tobacco mosaic virus (TMV). Moreover, the crude and a purified exopolysaccharide were proved to possess strong inhibitory effects against the virus infection. PMID- 29186926 TI - Structural Diversity and Biological Activities of Fungal Cyclic Peptides, Excluding Cyclodipeptides. AB - Cyclic peptides are cyclic compounds formed mainly by the amide bonds between either proteinogenic or non-proteinogenic amino acids. This review highlights the occurrence, structures and biological activities of fungal cyclic peptides (excluding cyclodipeptides, and peptides containing ester bonds in the core ring) reported until August 2017. About 293 cyclic peptides belonging to the groups of cyclic tri-, tetra-, penta-, hexa-, hepta-, octa-, nona-, deca-, undeca-, dodeca , tetradeca-, and octadecapeptides as well as cyclic peptides containing ether bonds in the core ring have been isolated from fungi. They were mainly isolated from the genera Aspergillus, Penicillium, Fusarium, Acremonium and Amanita. Some of them were screened to have antimicrobial, antiviral, cytotoxic, phytotoxic, insecticidal, nematicidal, immunosuppressive and enzyme-inhibitory activities to show their potential applications. Some fungal cyclic peptides such as the echinocandins, pneumocandins and cyclosporin A have been developed as pharmaceuticals. PMID- 29186930 TI - Protective Effects of Liquiritigenin against Citrinin-Triggered, Oxidative-Stress Mediated Apoptosis and Disruption of Embryonic Development in Mouse Blastocysts. AB - The mycotoxin citrinin (CTN), a natural contaminant in foodstuffs and animal feeds, exerts cytotoxic and genotoxic effects on various mammalian cells and embryos. A previous investigation by our group revealed potentially hazardous effects of CTN on mouse oocyte maturation and pre- and post-implantation embryo development via the induction of apoptosis. The present study showed that CTN induces apoptosis and inhibits cell proliferation in the inner cell mass of mouse blastocysts. Notably, we observed for the first time that both these effects are suppressed by liquiritigenin (LQ). LQ is a type of flavonoid isolated from Glycyrrhiza radix with several biochemical and pharmacological activities, including antioxidant and anti-inflammatory properties. The preincubation of blastocysts with LQ clearly prevented CTN-induced disruption of pre- and post implantation embryonic development and fetal weight loss, both in vitro and in vivo. CTN-induced damage processes directly promoted reactive oxygen species (ROS) generation, loss of mitochondrial membrane potential (MMP) and activation of caspase-9 and caspase-3, which were effectively blocked by LQ. Moreover, in an animal model, intravenous injection of dams with CTN (3 mg/kg/day) triggered apoptosis of blastocysts, disruption of embryonic development from the zygote to the blastocyst stage and a decrease in fetal weight. Pre-injection with LQ (5 mg/kg/day) effectively reduced apoptosis and impaired the cytotoxic effects of CTN on development. Our in vivo findings further confirm that CTN exposure via injection has the potential to impair pre- and post-implantation development, leading to apoptosis and the suppression of sequent embryonic development, which can be effectively prevented by LQ. PMID- 29186931 TI - Mixture Toxicity of Bensulfuron-Methyl and Acetochlor to Red Swamp Crayfish (Procambarus clarkii): Behavioral, Morphological and Histological Effects. AB - The mixture of bensulfuron-methyl and acetochlor (MBA) has been widely applied as a rice herbicide in China, but the mixture toxicity of MBA to aquatic organisms is largely unknown. The current study aims to investigate the acute effects of MBA to juvenile red swamp crayfish, Procambarus clarkii. Firstly, a 96 h semi static exposure was conducted to determine the Lethal Concentration 50 (LC50) values at 24, 48, 72 and 96 h, as well as to assess the behavioral and morphological effects. A second 96 h exposure was conducted at an MBA concentration of 50% of the 96 h LC50 (72.62 mg/L) to assess the histological changes in the gill, perigastric organ, muscle, heart, stomach, and midgut. The results showed that MBA exhibited low acute toxicity with the 24, 48, 72 and 96 h LC50 values of 191.25 (179.37-215.75), 166.81 (159.49-176.55), 154.30 (148.36 160.59) and 145.24 (138.94-151.27) mg/L, respectively. MBA-exposed crayfish showed body jerk, belly arch, equilibrium loss, body and appendage sway, and lethargy; and the dead crayfish showed dark gray or grayish-white body color and separated cephalothorax and abdomen. At 72.62 mg/L, MBA exposure caused significant histopathological alterations, mainly including the cuticular and epithelial degeneration of all the gills; atrophy of tubule lumina and cellular vacuolation of the perigastric organs (61.15 +/- 9.90% of the tubules showed lesions); epithelial hyperplasia (48.40 +/- 9.00%), myocardial fibers and epithelial cell lysis (17.30 +/- 2.01%), and hemocytic infiltration of the hearts; cuticular swelling (15.82 +/- 2.98%) and vacuolate connective tissue (11.30 +/- 2.47%) of the stomachs; atrophied bladder cell and fragmented longitudinal muscles (95.23 +/- 4.77%) of the midguts; and slight myofibers fragmentation and lysis (7.37 +/- 0.53%) of the abdominal muscles. Our results indicate that MBA can cause behavioral, morphological and histopathological effects on juvenile P. clarkii at relatively high concentrations, but its acute toxicity is low compared with many other common herbicides.

AB - Calcium phosphate materials (CaPs) are similar to inorganic part of human mineralized tissues (i.e., bone, enamel, and dentin). Owing to their high biocompatibility, CaPs, mainly hydroxyapatite (HA), have been investigated for their use in various medical applications. One of the most widely used ways to improve the biological and physicochemical properties of HA is ionic substitution with trace ions. Recent developments in bioceramics have already demonstrated that introducing foreign ions is also possible in other CaPs, such as tricalcium phosphates (amorphous as well as alpha and beta crystalline forms) and brushite. The purpose of this paper is to review recent achievements in the field of non apatitic CaPs substituted with various ions. Particular attention will be focused on tricalcium phosphates (TCP) and "additives" such as magnesium, zinc, strontium, and silicate ions, all of which have been widely investigated thanks to their important biological role. This review also highlights some of the potential biomedical applications of non-apatitic substituted CaPs. PMID- 29186934 TI - Joint Decision-Making and the Coordination of a Sustainable Supply Chain in the Context of Carbon Tax Regulation and Fairness Concerns. AB - Carbon tax regulation and consumers' low-carbon preference act as incentives for firms to abate emissions. Manufacturers can improve product sustainability and retailers can strengthen the promotion of low-carbon products as part of such abatement. Current incomplete rationality also affects product sustainability and low-carbon promotion level. In this context, we consider a supply chain with a manufacturer and a retailer and investigate the impacts of the manufacturer's and the retailer's fairness concerns on their production sustainability level, low carbon promotion level and profitability. We also explore the coordination contract. The results show that the manufacturer's and the retailer's fairness concerns decrease their product sustainability and low-carbon promotion level, together with the profits of the system and the manufacturer. With regard to the retailer's fairness concern, the product sustainability level and the manufacturer's profit are lower; moreover, the low-carbon promotion level and the profits of the supply chain and the retailer are higher. A revenue-sharing contract can coordinate the supply chain perfectly; however, members' fairness concerns increase the difficulty of coordination. Finally, the numerical results reveal that carbon tax regulation can encourage the manufacturer to enhance the product sustainability level. Further, the impacts on the low-carbon promotion level and firms' profitability are related to the cost coefficients of product sustainability. PMID- 29186933 TI - Targeting Autophagy in ALK-Associated Cancers. AB - Autophagy is an evolutionarily conserved catabolic process, which is used by the cells for cytoplasmic quality control. This process is induced following different kinds of stresses e.g., metabolic, environmental, or therapeutic, and acts, in this framework, as a cell survival mechanism. However, under certain circumstances, autophagy has been associated with cell death. This duality has been extensively reported in solid and hematological cancers, and has been observed during both tumor development and cancer therapy. As autophagy plays a critical role at the crossroads between cell survival and cell death, its involvement and therapeutic modulation (either activation or inhibition) are currently intensively studied in cancer biology, to improve treatments and patient outcomes. Over the last few years, studies have demonstrated the occurrence of autophagy in different Anaplastic Lymphoma Kinase (ALK)-associated cancers, notably ALK-positive anaplastic large cell lymphoma (ALCL), non-small cell lung carcinoma (NSCLC), Neuroblastoma (NB), and Rhabdomyosarcoma (RMS). In this review, we will first briefly describe the autophagic process and how it can lead to opposite outcomes in anti-cancer therapies, and we will then focus on what is currently known regarding autophagy in ALK-associated cancers. PMID- 29186929 TI - Integrated Immunomodulatory Mechanisms through which Long-Chain n-3 Polyunsaturated Fatty Acids Attenuate Obese Adipose Tissue Dysfunction. AB - Obesity is a global health concern with rising prevalence that increases the risk of developing other chronic diseases. A causal link connecting overnutrition, the development of obesity and obesity-associated co-morbidities is visceral adipose tissue (AT) dysfunction, characterized by changes in the cellularity of various immune cell populations, altered production of inflammatory adipokines that sustain a chronic state of low-grade inflammation and, ultimately, dysregulated AT metabolic function. Therefore, dietary intervention strategies aimed to halt the progression of obese AT dysfunction through any of the aforementioned processes represent an important active area of research. In this connection, fish oil-derived dietary long-chain n-3 polyunsaturated fatty acids (PUFA) in the form of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been demonstrated to attenuate obese AT dysfunction through multiple mechanisms, ultimately affecting AT immune cellularity and function, adipokine production, and metabolic signaling pathways, all of which will be discussed herein. PMID- 29186935 TI - Adult Nutrient Intakes from Current National Dietary Surveys of European Populations. AB - The World Health Organization (WHO) encourages countries to undertake national dietary survey (NDS) but implementation and reporting is inconsistent. This paper provides an up-to-date review of adult macro and micronutrient intakes in European populations as reported by NDS. It uses WHO Recommended Nutrient Intakes (RNIs) to assess intake adequacy and highlight areas of concern. NDS information was gathered primarily by internet searches and contacting survey authors and nutrition experts. Survey characteristics and adult intakes by gender/age group were extracted for selected nutrients and weighted means calculated by region. Of the 53 WHO Europe countries, over a third (n = 19), mainly Central & Eastern European countries (CEEC), had no identifiable NDS. Energy and nutrient intakes were extracted for 21 (40%) countries but differences in age group, methodology, under-reporting and nutrient composition databases hindered inter-country comparisons. No country met more than 39% WHO RNIs in all age/gender groups; macronutrient RNI achievement was poorer than micronutrient. Overall RNI attainment was slightly worse in CEEC and lower in women and female elderly. Only 40% countries provided adult energy and nutrient intakes. The main gaps lie in CEEC, where unknown nutrient deficiencies may occur. WHO RNI attainment was universally poor for macronutrients, especially for women, the female elderly and CEEC. All countries could be encouraged to report a uniform nutrient set and sub analyses of nationally representative nutrient intakes. PMID- 29186936 TI - Endoscope-Assisted Cochlear Implantation. AB - OBJECTIVES: Our aim was to present our endoscope-assisted cochlear implantation (CI) technique, in which the middle ear landmarks were identified through the facial recess exposure by using an endoscopic view without elevating the tympanic annulus. The secondary goal was to assess whether the situation of difficult surgical exposure could be predicted by evaluating preoperative axial computed tomography (CT) examinations. METHODS: CT examinations and surgical outcomes of endoscope-assisted CI surgeries were analyzed. RESULTS: A total of 179 CI operations performed in 27 adults (15.1%) and 152 children (84.9%) were retrospectively evaluated. It was found that in 14 cases (7.8%), endoscopic examination contributed substantially in identifying the round window (RW) membrane correctly. Endoscopic identification of the RW through the posterior tympanotomy enabled us to perform a straightforward surgery in all these cases, without the need for switching to a bony cochleostomy or alternative surgical techniques. The difficulty in the surgical exposure was predicted preoperatively by examining the axial CT scans in six of the 14 cases (42.8%) for which endoscopic assistance was necessary in order to identify the RW correctly. CONCLUSION: The main benefit of endoscope-assisted CI is the improved visibility leading to a panoramic view of the RW region. The implementation of transfacial recess endoscopic examination into the conventional CI technique is helpful to avoid problems during surgical orientation. However, the difficulty in the surgical exposure of the RW cannot be reliably predicted by the subjective evaluation of preoperative CT scans and more studies are needed to obtain reliable criteria. PMID- 29186937 TI - How to use PET/CT in the evaluation of response to radiotherapy. AB - Radiotherapy is a major treatment modality for many cancers. Tumor response after radiotherapy determines the subsequent steps of the patient's management (surveillance, adjuvant or salvage treatment and palliative care). Tumor response assessed during radiotherapy offers a promising opportunity to adapt the treatment plan to reduced or increased target volume, to specifically target sub volumes with relevant biological characteristics (metabolism, hypoxia, proliferation, etc.) and to further spare the organs at risk. In addition to its role in the diagnosis and the initial staging, Positron Emission Tomography combined with a Computed Tomography (PET/CT) provides functional information and is therefore attractive to evaluate tumor response. The aim of this paper is to review the published data addressing PET/CT as an evaluation tool in irradiated tumors. Reports on PET/CT acquired at various times (during radiotherapy, after initial (chemo-) radiotherapy, after definitive radiotherapy and during posttreatment follow-up) in solid tumors (lung, head-and-neck, cervix, esophagus, prostate and rectum) were collected and reviewed. Various tracers and technical aspects are also discussed. 18F-FDG PET/CT has a well-established role in clinical routine after definitive chemo-radiotherapy for locally advanced head and-neck cancers. 18F-choline PET/CT is indicated in prostate cancer patients with biochemical failure. 18F-FDG PET/CT is optional in many other circumstances and the clinical benefits of assessing tumor response with PET/CT remain a field of very active research. The combination of PET with Magnetic Resonance Imaging (PET/MRI) may prove to be valuable in irradiated rectal and cervix cancers. Tumor response can be evaluated by PET/CT with clinical consequences in multiple situations, notably in head and neck and prostate cancers, after radiotherapy. Further clinical evaluation for most cancers is still needed, possibly in association to MRI. PMID- 29186938 TI - Occurrence and clinical characteristics of hepatocellular carcinoma in the north eastern Poland AB - : Hepatocellular carcinoma (HCC) is the fifth most common malignancy and the third leading cause of cancerrelatedmortality worldwide. Risk factors for this malignancy include liver cirrhosis, HBV or HCV infection,fatty liver disease. THE AIM OF STUDY: This study aims to assess the occurrence and clinical characteristics of HCC in theNortheastern Poland between 2011 and 2015. The number of primary lesions, their size and location within theliver were analysed. The risk factors for this cancer in studied population have been identified. The usefulnessof AFP screening and imaging studies for the diagnosis of HCC were assessed. A preliminary analysis of theefficacy of anti-tumour therapy was performed. RESULTS: Sixty-seven patients (28% female and 72% male) with diagnosed HCC were enrolled. HCC diagnosiswas established according to the criteria proposed by the International Consensus Group for Hepatocellular Neoplasia.Of the 67 patients in the study, 7 (10%) were aged 30 to 50 years and 60 patients (90%) were aged 51 years and older.During the period 2011-2015, an increase in HCC incidence was observed. In studied group the most prevalent (31%)were patients with 2 tumours localised in the 6th, 7th or 8th segments of the liver. Metastatic tumours were presentin 15% and portal vein thrombosis in 9% of patients. Risk factors assessment revealed that in 72% of patients HCCcoexisted with cirrhosis, 33% of patients were HCV-infected, 30% had HBV infection, and 15% were diagnosedwith NASH. Elevated serum AFP level was observed in 83% of patients with liver cirrhosis, and in 58% of patientswithout cirrhosis (p <0.05). Liver transplantation was the best therapeutic option. The efficacy of ablation/resection incombination with sorafenib vs. ablation/partial resection was comparable. CONCLUSION: There has been an increase in the number of HCC cases in North-eastern Poland in last fewyears. HCC is more common in men aged 50 years and older. Increased serum AFP level is a useful marker forthe diagnosis and monitoring of HCC treatment in patients with liver cirrhosis. PMID- 29186939 TI - Periapical abscess - etiology, pathogenesis and epidemiology AB - Inflammation of the pulp and periapical tissues is the main cause of tooth loss in patients worldwide, therefore endodontics is one of the most rapidly developing specialties in dentistry. Despite proper endodontic treatment, in many cases it is not possible to determine the etiology of infection or the reason for its relapse.Many research studies indicate that infections of the periapical tissues are mainly caused by strictly anaerobic bacteria. At present, more and more often the composition of the microflora within the inflammatory lesions is being evaluated with the use of molecular techniques, which showed that classical culture methods are not able to determine the etiology of infections of the periapical tissues. The results of these studies contributed to the major changes in our understanding of the microbiome composition in the endodontium. Purulent endodontic lesions are particularly important, as they may lead to many severe - even life-threatening - systemic complications. PMID- 29186940 TI - Patient's health awareness as a significant link in the process of melanoma diagnostics AB - INTRODUCTION: Melanoma malignum is a relatively rare neoplasm, among all skin neoplasms, but its relatedmortality is high. Diagnosis and removal of the lesion at an early stage are crucial for significant increase inchances of survival andis highly determined by patients' awareness in terms of melanoma risk factors. AIM: The aim of the study was to determine the level of patients' knowledge and awareness in terms of skinmelanoma, its risk factors, health promoting behaviors, as well as learning about the sources of this knowledge. MATERIAL AND METHODS: Study group included 142 patients from the Department of Dermatology at theUniversity Hospital in Krakow. Patients were divided into two groups: 88 people from the VideodermatoscopyOffice (VDO), 53 people from other offices (OO). A questionnaire including 40 questions was used as a researchtool for the studied group. It applied to data obtained from demographic data, determination of skin phototypeaccording to Fitzpatrick scale, history of possible suspicious or removed skin lesions, awareness in terms ofskin neoplasm prevention, patients' knowledge about skin melanoma, and its source. Collected data were thensubjected to statistical analysis. RESULTS: VDO patients provided more accurate answers to questions regarding melanoma, prognosis, risk factors,possible melanoma sites, and treatment. Melanoma was correctly described as a malignant neoplasm by 92% peoplefrom the VDO group, and 65% of the OO group, surgical melanoma removal as the correct method was indicated by84% vs. 68% and excessive exposure to sunlight 88.2% vs. 74%, sunbathing without use of skin sunscreen lotions92.1% vs. 84%, melanoma in the family 75% vs. 66%, use of tanning salons 80.3% vs. 66%, exposure to excessive suneffect during childhood 67.1% vs. 34%, previously removed melanoma 44.7% vs. 24%, use of tanning beds 80.3% vs.66%, high number of nevi 68.4% vs. 38% as melanoma risk factors, features of alarming nevi (multiple colors 77.3%vs. 56.6%, growth over time 75% vs. 50.9%, irregular borders 72.7% vs. 45.3%, diameter >5 mm 72.7% vs. 45.3%,asymmetrical shape 61.4% vs. 67.9%). 51.3% of patients of the VDO vs. 8% of the OO group indicated physician asthe source of knowledge and 79,1% vs. 61% of them perform regular self-examination. CONCLUSION: Crucial links in the process of melanoma diagnostics include: health awareness of patients,involvement of physicians, both dermatologists, and primary healthcare physicians, as well as appropriatelyprepared and comprehensive information and education provided by media. According to the foregoing information,physicians have to be ready not only to diagnose the problem reported by a patient, but also to take theinitiative and educate patients in terms of disease character, risk factors and motivating to perform self-examinationof the skin, as this provides the most measurable results. PMID- 29186941 TI - Is one minute enough to convince parents to vaccinate their child? AB - INTRODUCTION: A growing number of parents refuse childhood vaccination. This situation may be causedby many reasons, but surely the lack of parental knowledge is one of them. A physician, as the most reliablesource of information about vaccination, plays an important role in parental education. How can we successfullyinform parents about vaccinations, when faced with primary care visit being too short? The aim of this studywas to assess the impact of three types of information about pneumococcal vaccine on parental decision-making. MATERIAL AND METHODS: The children were enrolled based on the inclusion and exclusion criteria. Theparents received one of three types of vaccination information: simple oral, extent oral and written one. The endpointof the study was the length of time between the day parents were informed by physician and the day firstdose of vaccine was administered. RESULTS: The percentage of vaccinated children was: 12.8% for written information, 14.7% for extended and20.8% for simple one. The simple information was significantly associated with increased chances for vaccinationin the following groups: children with a birth weight <3355 g (p<0.025), born with a gestational age <40weeks (p<0.015) and in the group with lower healthcare utilization (p<0.020). The extended information wassignificantly associated with increased chances for vaccination in the group of chronically ill mothers (p<0.045). CONCLUSIONS: Physicians should provide parents with personalized immunization information. One minutemay be sufficient to convince parents to vaccinate their child, especially if healthcare utilization of family is low.Chronically ill parents should be given extended information. Discussion about vaccinations with parents shouldnot be replaced by written vaccination information. PMID- 29186942 TI - Methods of testing repellent efficiency against ticks AB - The use of repellents is the most important in the tick-bite protection. The tests of repellents efficiency shall give strict answer whether ticks are repelled effectively or not by a given agent. Methods of testing repellent efficiency can be divided in in three groups: experiments without tick host and host stimuli; studies simulating host stimuli, methods of testing repellents on animals or human volunteers. Studies on protected human volunteers are the nearest practical conditions of repellent use. However, there is sometimes a need of testing products with unknown toxicity to man; in such circumstances their efficiency should be evaluated in experiments in simulated human body conditions but without a person. PMID- 29186943 TI - Modified minimally invasive direct anterior approach through a bikini incision for total hip arthroplasty: technique and results in young female patients. AB - Direct anterior approach for THA has gained popularity over the last years. However, concerns have been raised regarding the cosmetic, related to the incision that does not respect the Langer's skin tension line and may produce hypertrophic scars. The aim of this study was to analyze the preliminary results in 22 young female patients undergoing THA through a minimally invasive direct anterior approach using a modified oblique bikini incision. Clinical evaluations showed an improvement of WOMAC, UCLA and Harris Hip Score at 5-month follow-up. The technique ensured proper implant positioning and showed advantages in terms of complications, transfusion rates, hospital length of stay and functional recovery. From the aesthetic point of view, the expected cosmetic results were obtained. Minimally invasive direct anterior approach using a modified oblique bikini incision represent a viable option for THA, combining both the advantages of a minimal invasive procedure with a better aesthetic appearance. PMID- 29186944 TI - Direct vertebral rotation and differently shaped dual rod translation technique in adolescent idiopathic scoliosis. AB - Direct vertebral rotation (DVR) is widely used to correct the axial deformity in adolescent idiopathic scoliosis (AIS). Indirect rotation techniques may help DVR in order to improve outcome. Vertebral translation technique combined with the use of two differently shaped rods resulted effective in reducing the rib hump deformity. The aim of this study is to describe the technique and evaluate the efficacy of combined DVR and vertebral translation technique on axial deformity correction. Mean follow-up was 2.7 years. Cobb angle, kyphosis angle, apical vertebrae axial rotation angle, SRS-22 questionnaire of 30 AIS patients treated with combined DVR and differently shaped dual rods translation technique were collected and compared preoperatively and postoperatively. At the last follow-up no screw pull-out, nonunion or loss of correction were recorded. The combination of DVR and differently shaped dual rods translation technique in AIS can provide good three-dimensional correction and improvement of patient's quality of life. PMID- 29186945 TI - Correlation between gamma glutamyltransferase fractions and bone quality. AB - Gamma-glutamyltransferase (GGT) has been recently identified as a bone-resorbing factor. The aim of this study was to investigate the association between plasma GGT fractions levels and bone quality. Plasma GGT fractions were analysed by gel filtration chromatography. Bone quality was established quantitatively by two micro-CT derived microarchitectural parameters: the BV/TV (mineralised bone volume/total volume), and the SMI (structure model index) that describes the rod like (low resistant) or plate-like (high-resistant) shape of bone trabeculae. We enrolled 93 patients hospitalised for elective total hip replacement (group Arthrosis, n=46) or for proximal femoral fracture (group Fracture, n=47). Patients within the first quartile of BV/TV (Q1, osteoporotic patients, n=6) showed higher levels of b-GGT fraction [median (min-max): 3.37 (1.42-6.81)] compared to patients with normal bone density (fourth quartile Q4, n=10; 1.40 (0.83-4.36); p=0.0393]. Also, according to SMI, b-GGT value was higher in the subgroup with bone fragility [Q1, n=8: 1.36 (0.43-4.36); Q4, n=8: 5.10 (1.4 7.60); p=0.0117]. In conclusion, patients characterised by fragile bone structure showed specifically higher levels of plasma b-GGT activity thus suggesting fractional GGT analysis as a possible biomarker in the diagnosis of osteoporosis. PMID- 29186946 TI - Use of autologous bone marrow cells concentrate enriched with platelet-fibrin on extensor mechanism allograft reconstruction for extensor mechanism failure following total knee arthroplasty. AB - Allografts techniques remain the best reconstructive strategy for chronic extensor mechanism lesions after total knee arthroplasty (3) but outcomes depend strictly on the host tissue-allograft junctions healing. The purpose of this study is to evaluate if modern techniques of adding autologous bone marrow cells concentrate enriched with platelet-rich fibrin, provide better healing of the allograft. We present the case of an 86 years old patient affected by patellar tendon rupture after TKA. A whole extensor mechanism allograft was performed adding a bone marrow cells concentrate enriched with platelet-rich fibrin on the host tissue-allograft junctions. Preoperatively and at each follow-up the value of Knee Society Score and radiographic consolidation signs were recorded. Radiographic controls showed clear signs of consolidation already at 1 months follow-up and a solid fusion at 3 months. This case report describes a valid method to improve healing using a tissue-construct engineered with stem cells and growth factors. PMID- 29186947 TI - One-step cartilage repair with minced chondral fragment on a composite scaffold: an in vitro human study at low oxygen tension. AB - Minced cartilage fragments are a viable cell source for one stage cartilage repair. However, the joint surface is a low oxygen tension microenvironment and little evidence is present in literature regarding the behaviour of cartilage fragments in this peculiar condition. The aim of the study is i) to verify if low oxygen tension could negatively influence chondrocyte outgrowth from cartilage fragments into a Hyaluronic-Acid(HA)/fibrin scaffold and ii) to evaluate its effects on the behaviour of migrating chondrocyte, compared to normoxic condition. A slight decrease in chondrocyte migration and proliferation was observed in low oxygen tension cultures. Conversely, an increase in the expression of SOX9, beta-catenin, HIFs, collagen-I and II (p<0.05) in migrating chondrocytes from low oxygen tension cultures was present. Thus, a long term- exposure at low oxygen tension seems to improve the chondrocytic phenotype expression of cell outgrowing from cartilage fragments onto a HA/fibrin scaffold. PMID- 29186948 TI - Bone cement implantation syndrome: a thromboelastographic study of the effect of bone cement on coagulation. AB - Bone cement implantation syndrome (BCIS) is a rare form of intraoperative pulmonary embolism (EP) that occurs during cementation. It can be explained by two main theories: the monomer mediated model and the mechanic model. Our goal is to evaluate thromboelastographic changes in patients undergoing surgery for femoral neck fractures. We recruited 32 patients with a femoral neck fracture. The average age was 81.91 years (range 62-95). The patients were divided in two different groups: cemented hip arthroplasty (CC, 13 patients) and other surgical non-cemented techniques (SC, non-cemented hip arthroplasty, osteosynthesis). The coagulation was evaluated by TEG in the early pre-operatory (time A) and post operatory (time B), both on native blood and on blood added with Heparinase. We used the t-test to compare the differences between the two groups. The coagulation index CI was modified on hypercoagulability by surgery in both groups, but without statistical significance between the two groups (p>0.05). R parameter decreases between time A and time B in the same way in both groups (p>0.05). Parameter MA had no major variations between time A and B, without statistical significance (p>0.05). From our study it is evident that although the surgery would result in a change in the layout of the TEG toward hypercoagulability, this is similar both in cemented and non-cemented surgical interventions for femoral neck fractures in elderly patients. An altered coagulation does not appear to be the cause or a factor in determining the BCIS. PMID- 29186949 TI - Part by Part: Synthetic Biology Parts Used in Solventogenic Clostridia. AB - The solventogenic Clostridia are of interest to the chemical industry because of their natural ability to produce chemicals such as butanol, acetone and ethanol from diverse feedstocks. Their use as whole cell factories presents multiple metabolic engineering targets that could lead to improved sustainability and profitability of Clostridium industrial processes. However, engineering efforts have been held back by the scarcity of genetic and synthetic biology tools. Over the past decade, genetic tools to enable transformation and chromosomal modifications have been developed, but the lack of a broad palette of synthetic biology parts remains one of the last obstacles to the rapid engineered improvement of these species for bioproduction. We have systematically reviewed existing parts that have been used in the modification of solventogenic Clostridia, revealing a narrow range of empirically chosen and nonengineered parts that are in current use. The analysis uncovers elements, such as promoters, transcriptional terminators and ribosome binding sites where increased fundamental knowledge is needed for their reliable use in different applications. Together, the review provides the most comprehensive list of parts used and also presents areas where an improved toolbox is needed for full exploitation of these industrially important bacteria. PMID- 29186950 TI - Descriptor Data Bank (DDB): A Cloud Platform for Multiperspective Modeling of Protein-Ligand Interactions. AB - Protein-ligand (PL) interactions play a key role in many life processes such as molecular recognition, molecular binding, signal transmission, and cell metabolism. Examples of interaction forces include hydrogen bonding, hydrophobic effects, steric clashes, electrostatic contacts, and van der Waals attractions. Currently, a large number of hypotheses and perspectives to model these interaction forces are scattered throughout the literature and largely forgotten. Instead, had they been assembled and utilized collectively, they would have substantially improved the accuracy of predicting binding affinity of protein ligand complexes. In this work, we present Descriptor Data Bank (DDB), a data driven platform on the cloud for facilitating multiperspective modeling of PL interactions. DDB is an open-access hub for depositing, hosting, executing, and sharing descriptor extraction tools and data for a large number of interaction modeling hypotheses. The platform also implements a machine-learning (ML) toolbox for automatic descriptor filtering and analysis and scoring function (SF) fitting and prediction. The descriptor filtering module is used to filter out irrelevant and/or noisy descriptors and to produce a compact subset from all available features. We seed DDB with 16 diverse descriptor extraction tools developed in house and collected from the literature. The tools altogether generate over 2700 descriptors that characterize (i) proteins, (ii) ligands, and (iii) protein ligand complexes. The in-house descriptors we extract are protein-specific which are based on pairwise primary and tertiary alignment of protein structures followed by clustering and trilateration. We built and used DDB's ML library to fit SFs to the in-house descriptors and those collected from the literature. We then evaluated them on several data sets that were constructed to reflect real world drug screening scenarios. We found that multiperspective SFs that were constructed using a large number of diverse DDB descriptors capturing various PL interactions in different ways outperformed their single-perspective counterparts in all evaluation scenarios, with an average improvement of more than 15%. We also found that our proposed protein-specific descriptors improve the accuracy of SFs. PMID- 29186951 TI - Exposure Assessment of Acetamide in Milk, Beef, and Coffee Using Xanthydrol Derivatization and Gas Chromatography/Mass Spectrometry. AB - Acetamide has been classified as a possible human carcinogen, but uncertainties exist about its levels in foods. This report presents evidence that thermal decomposition of N-acetylated sugars and amino acids in heated gas chromatograph injectors contributes to artifactual acetamide in milk and beef. An alternative gas chromatography/mass spectrometry protocol based on derivatization of acetamide with 9-xanthydrol was optimized and shown to be free of artifactual acetamide formation. The protocol was validated using a surrogate analyte approach based on d3-acetamide and applied to analyze 23 pasteurized whole milk, 44 raw sirloin beef, and raw milk samples from 14 different cows, and yielded levels about 10-fold lower than those obtained by direct injection without derivatization. The xanthydrol derivatization procedure detected acetamide in every food sample tested at 390 +/- 60 ppb in milk, 400 +/- 80 ppb in beef, and 39 000 +/- 9000 ppb in roasted coffee beans.

AB - In the search for new antiresistance acetohydroxyacid synthase (AHAS, EC 2.2.1.6) inhibitors to combat weed resistance associated with AHAS mutations, a series of 2-[(4,6-dimethoxy-1,3,5-triazin-2-yl)oxy]-6-(substituted phenoxy)benzoic acids 11 38 were designed and synthesized via the strategy of conformational flexibility analysis. Compounds 21, 22, 26, 33, 36, and 38 with high potency against both wild-type AtAHAS and its P197L mutant were identified as promising candidates with low resistance factors (RF, defined as the ratio between the ki values toward P197L mutant and wild-type AHAS) ranging from 0.73 to 6.32. Especially, compound 22 (RF = 0.73) was further identified as the most potent antiresistance AHAS inhibitor because of its significantly reduced resistance level compared with that of tribenuron-methyl (RF = 2650) and bispyribac (RF = 4.57). Furthermore, compounds 26, 33, 36, and 38 also displayed promising herbicidal activities against sensitive and resistant (P197L) Descurainia sophia at the dosage of 75-150 g of active ingredient (ai)/ha. Notably, compounds 33 and 38 still maintained over 60% herbicidal activity toward the resistant weed even at much lower dosages (37.5 g ai/ha). Therefore, the designed scaffold has the great potential to discover new candidate compounds for the control of weed resistance associated with AHAS mutation.

AB - Carbapenem-resistant Enterobacteriaceae have recently become an important cause of morbidity and mortality due to healthcare-associated infections. Most commonly used diagnostic methods are incompatible with fast and accurate directed therapy. We report here the direct identification of the blaOXA48 gene, which codes for the carbapenemase OXA-48, in lysate samples from Klebsiella pneumoniae. The method is PCR-free and label-free. It is based on the measurement of changes in the stiffness of DNA self-assembled monolayers anchored to microcantilevers that occur as a consequence of the hybridization. The stiffness of the DNA layer is measured through changes of the sensor resonance frequency upon hybridization and at varying relative humidity.

AB - Fabrication and comparative analysis of the gas sensing devices based on individualized single-walled carbon nanotubes of four different types (pristine, boron doped, nitrogen doped, and semiconducting ones) for detection of low concentrations of ammonia is presented. The comparison of the detection performance of different devices, in terms of resistance change under exposure to ammonia at low concentrations combined with the detailed analysis of chemical bonding of dopant atoms to nanotube walls sheds light on the interaction of NH3 with carbon nanotubes. Furthermore, chemoresistive measurements showed that the use of semiconducting nanotubes as conducting channels leads to the highest sensitivity of devices compared to the other materials. Electrical characterization and analysis of the structure of fabricated devices showed a close relation between amount and quality of the distribution of deposited nanotubes and their sensing properties. All measurements were performed at room temperature, and the power consumption of gas sensing devices was as low as 0.6 MUW. Finally, the route toward an optimal fabrication of nanotube-based sensors for the reliable, energy-efficient sub-ppm ammonia detection is proposed, which matches the pave of advent of future applications.

AB - Solid-electrolyte interphase (SEI) is the key component that enables all advanced electrochemical devices, the best representative of which is Li-ion battery (LIB). It kinetically stabilizes electrolytes at potentials far beyond their thermodynamic stability limits, so that cell reactions could proceed reversibly. Its ad hoc chemistry and formation mechanism has been a topic under intensive investigation since the first commercialization of LIB 25 years ago. Traditionally SEI can only be formed in nonaqueous electrolytes. However, recent efforts successfully transplanted this concept into aqueous media, leading to significant expansion in the electrochemical stability window of aqueous electrolytes from 1.23 V to beyond 4.0 V. This not only made it possible to construct a series of high voltage/energy density aqueous LIBs with unprecedented safety, but also brought high flexibility and even "open configurations" that have been hitherto unavailable for any LIB chemistries. While this new class of aqueous electrolytes has been successfully demonstrated to support diversified battery chemistries, the chemistry and formation mechanism of the key component, an aqueous SEI, has remained virtually unknown. In this work, combining various spectroscopic, electrochemical and computational techniques, we rigorously examined this new interphase, and comprehensively characterized its chemical composition, microstructure and stability in battery environment. A dynamic picture obtained reveals how a dense and protective interphase forms on anode surface under competitive decompositions of salt anion, dissolved ambient gases and water molecule. By establishing basic laws governing the successful formation of an aqueous SEI, the in-depth understanding presented in this work will assist the efforts in tailor-designing better interphases that enable more energetic chemistries operating farther away from equilibria in aqueous media. PMID- 29186956 TI - How viruses infiltrate the central nervous system. AB - Central nervous system is protected by the blood-brain barrier, which represents a physical, metabolic and transport barrier and is considered to be a part of a highly dynamic system termed neurovascular unit. Several pathogens, among them viruses, are able to invade the brain. Traversal of viruses across the blood brain barrier is an essential step for the invasion of the central nervous system and can occur by different mechanisms - by paracellular, transcellular and/or by "Trojan horse" pathway. Penetration of viruses to brain can lead to the blood brain barrier dysfunction, including increased permeability, pleocytosis and encephalopathy. Viruses causing the central nervous system infections include human immunodeficiency virus type 1, rhabdovirus, different flaviviruses, mouse adenovirus type 1, herpes simplex virus, influenza virus, parainfluenza virus, reovirus, lymphocytic choriomeningitis virus, arbovirus, cytomegalovirus, mumps virus, parvovirus B19, measles virus, human T-cell leukemia virus, enterovirus, morbillivirus, bunyaviruses, togaviruses and others. In this review we summarized what is known about the routes of how some viruses enter the brain and how neurons and glial cells react to infection. PMID- 29186957 TI - The human pegivirus: A new name for an "ancient" virus. Can transfusion medicine come up with something new? AB - Human pegivirus (HPgV, formerly called GB virus C/hepatitis G virus) is a poorly understood RNA virus of the Flaviviridae family. The HPgV infection is common worldwide and the virus is likely transmitted by blood products. At this time, no causal association between HPgV and human diseases has been identified. While waiting for new findings to better understand the Pegivirus genus, the aim of our narrative review is to discuss the currently available information on HPgV focusing on its prevalence in blood donors and its potential threat to transfusion safety. PMID- 29186958 TI - Tick-borne viruses. AB - Tick-borne viruses (TBVs) belong to the largest biological group known as arboviruses with unique mode of transmission by blood-feeding arthropods (ticks, mosquitoes, sand flies, biting midges, etc.) to a susceptible vertebrate host. Taxonomically, it is a heterogenous group of vertebrate viruses found in several viral families. With only one exception, African swine fever virus, all TBVs have a RNA genome. To date, at least 160 tick-borne viruses are known, some of them pose a significant threat to human and animal health worldwide. Recently, a number of established TBVs has re-emerged and spread to new geographic locations due to the influence of anthropogenic activities and few available vaccines. Moreover, new emerging tick-borne diseases are constantly being reported. Major advances in molecular biotechnologies have led to discoveries of new TBVs and further genetic characterization of unclassified viruses resulting in changes in TBVs classification created by the International Committee for the Taxonomy of Viruses. Although TBVs spend over 95% of their life cycle within tick vectors and the role of ticks as vectors has been known for over 100 years, our knowledge about TBVs and molecular processes involved in the virus-tick interactions is scarce. PMID- 29186959 TI - Molecular characterization of two sugarcane streak mosaic virus isolates from Iran with emphasis on its population structure. AB - Sugarcane streak mosaic virus (SCSMV; the genus Poacevirus, the family Potyviridae) is an economically important causal agent of sugarcane mosaic disease in Asia. In this study, for the first time, we determined the complete genomic sequences of two Iranian SCSMV isolates, IR-Khuz6 and IR-Khuz57 from sugarcane. The sequences of both isolates were 9,782 nucleotides (nt) long, excluding the 3' poly(A) tail. Both of them contained a 5'-untranslated region (UTR) of 199 nt, an open reading frame of 9,393 nt encoding a polyprotein of 3,130 amino acids (aa), and 3'-UTR of 190 nt. SCSMV-IR-Khuz6 and IR-Khuz57 genome nucleotide sequences were in 97.7% identical and shared identities of 81-92.4% with 10 other SCSMV isolates available in the GenBank. The highest identity was shared with the isolate PAK (NC_014037) from Pakistan. When separate genes were compared, most of the genes shared the highest identities with Pakistani isolate. Phylogenetic analysis of the complete genomic nucleotide and polyprotein amino acid sequences reveals that all SCSMV isolates clustered into two main groups. Both IR-Khuz6 and IR-Khuz57 clustered with isolates from Pakistan (PAK) and India (IND671) in group II but formed a separate subgroup. Population genetic analysis revealed greater between-group than within-group evolutionary divergence values, further supporting the results of the phylogenetic analysis. The results indicate that gene flow and selection pressure are important evolutionary factors shaping the genetic structure of SCSMV populations with implications for global exchange of sugarcane germplasm. PMID- 29186960 TI - Identification of novel E347Q and G362K amino acid substitutions in HN neutralization epitope and major antigenic difference in novel sub-genotype VIIj isolates. AB - Hemagglutinin-neuraminidase (HN) protein of Newcastle disease virus (NDV) plays a crucial role in induction of immune response against Newcastle disease infection. Mutation in residues 347 and 362 of HN linear antigenic site has been identified to be responsible for antigenic variations. Hence we studied antigenic difference between sub-genotype VIIj isolates and vaccine strains by the use of polyclonal serum against LaSota strain in hemagglutination inhibition test. Furthermore, epitope patterns of the isolates under study were analyzed and compared to HN sequences in GenBank. The results demonstrated that new Newcastle disease isolates (Mazandaran and Behshahr) had hemagglutination inhibition (HI) titer three and five, respectively while LaSota strain titer was eight. In addition, observation of sequences and epitope patterns revealed three unique amino acid substitutions (D144N, E347Q and G362K) in HN protein. E347Q and G362K mutations were located in neutralization antigenic site. Thus, we suggest that, these two novel amino acid substitutions in major linear epitope might be responsible for antigenic variation and decrease of HI activity. PMID- 29186961 TI - Relationship between PPP1R15A gene polymorphism (rs611251) and Epstein-Barr virus associated tumors. AB - Protein phosphatase 1, regulatory subunit 15A (PPP1R15A), also known as growth arrest and DNA damage-inducible protein GADD34, plays a vital role in promoting cell death and the unfolded protein response (UPR). In order to explore whether the SNP (rs611251) of PPP1R15A gene has a role in different types of Epstein-Barr virus (EBV) - associated tumors, we detected the PPP1R15A gene rs611251 polymorphism in 195 cases of EBV positive tumors (93 lymphomas, 48 gastric carcinomas, 54 nasopharyngeal carcinomas), 208 cases of EBV-negative tumors (136 gastric carcinoma, 19 nasopharyngeal carcinomas, 53 lymphomas) and 113 peripheral blood samples from healthy individuals. Compared with normal controls, the wild type TT and allele T of rs611251 showed higher frequency in gastric carcinoma (GCs), nasopharyngeal carcinomas (NPCs) and lymphomas. However, there was no significant difference between EBV-associated gastric (EBVaGC) and EBVnGC, EBV positive NPCs and EBV-negative NPCs, EBV-related lymphomas and EBV-negative lymphomas in rs611251 of PPP1R15A. In conclusion, the PPP1R15A rs611251 polymorphism was significantly related to three kinds of tumors. Nevertheless, EBV has no obvious effect on PPP1R15A rs611251 polymorphism of NPC, GC and lymphoma. What's more, the genotype TT and allele T could be risk factors for NPC, GC and lymphoma. Our study explores the relationship between PPP1R15A gene polymorphism (rs611251) and Epstein-Barr virus-associated tumors for the first time. PPP1R15A gene SNP (rs611251) have association with multiple tumor types, which may provide some new clues to the detection and treatment of tumors. PMID- 29186962 TI - Genomic and phylogenetic evidence that Maize rough dwarf and Rice black-streaked dwarf fijiviruses should be classified as different geographic strains of a single species. AB - Maize rough dwarf disease (MRDD) has long been known as one of the most devastating viral diseases of maize worldwide and is caused by single or complex infection by four fijiviruses: Maize rough dwarf virus (MRDV) in Europe and the Middle East, Mal de Rio Cuarto virus (MRCV) in South America, rice black-streaked dwarf virus (RBSDV), and Southern rice black-streaked dwarf virus (SRBSDV or Rice black-streaked dwarf virus 2, RBSDV-2) in East Asia. These are currently classified as four distinct species in the genus Fijivirus, family Reoviridae, but their taxonomic status has been questioned. To help resolve this, the nucleotide sequences of the ten genomic segments of an Italian isolate of MRDV have been determined, providing the first complete genomic sequence of this virus. Its genome has 29144 nucleotides and is similar in organization to those of RBSDV, SRBSDV, and MRCV. The 13 ORFs always share highest identities (81.3 97.2%) with the corresponding ORFs of RBSDV and phylogenetic analyses of the different genome segments and ORFs all confirm that MRDV clusters most closely with RBSDV and that MRCV and SRBSDV are slightly more distantly related. The results suggest that MRDV and RBSDV should be classified as different geographic strains of the same virus species and we suggest the name cereal black-streaked dwarf fijivirus (CBSDV) for consideration. PMID- 29186963 TI - Molecular epidemiology and genetic diversity of duck hepatitis A virus type 3 in Shandong province of China, 2012-2014. AB - The infections with duck hepatitis A virus type 3 (DHAV-3) become common in eastern Asia. To better understand the molecular evolution and genetic variation of DHAV-3, a total of 482 dead Cherry Valley duckling liver samples collected from Shandong province of China during 2012-2014 were tested, and the complete P1 coding sequences of 18 DHAV-3 strains were analyzed. The detection rate of DHAV-3 was 64.5% (311/482) in clinical liver samples and 73.0% (92/126) in duckling flocks. The P1 genes of the 18 DHAV-3 isolates shared 91.9%-99.0% nucleotide similarity and 95.2%-100% amino acid similarity with those of the other 26 reference strains. Based on the P1 and VP1 gene sequences, phylogenetic analysis results indicated that the genotyping of DHAV-3 strains presented a distinct geographical distribution. Except B63 strain, all Chinese strains isolated from different host species (duck or goose) at different time were classed into the CH genotype. All Korean and Vietnamese strains belonged to the KV genotype, and all the Korean strains were clustered into KV1 subgenotype, while B63 strain and the Vietnamese strains from different host species (duck or goose) were clustered into KV2 subgenotype. Ten variable amino acid residues were highly conserved within genotypes or subgenotypes in the VP0, VP3 and VP1, respectively, which were possibly the geographic molecular markers of DHAV-3. To the best of our knowledge, this is the first study about the genetic variation of the P1 gene of different DHAV-3 strains, which will be helpful for understanding of the molecular epidemiology of DHAV-3. PMID- 29186964 TI - Yeast two-hybrid and pull-down assays propose an interaction between P50 of apple chlorotic leaf spot virus and PR-10 of Malus sylvestris cv. R12740-7A. AB - Apple chlorotic leaf spot virus (ACLSV) movement protein (P50) is involved in cell-to-cell transport and influences the long-distance spread of silencing activity. Previously, we obtained 69 P50-interacting proteins from Malus sylvestris cv. R12740-7A and using bioinformatics analyzed their biological functions. In this study, we used the GAL4-based two-hybrid yeast system and His pull-down assays to confirm an interaction between PR-10 of M. sylvestris cv. R12740-7A and ACLSV P50. Our results provide a theoretical basis for further research on the biological function of PR-10 in ACLSV infection and the interacting mechanism between host and virus. PMID- 29186965 TI - Genome sequence of a distinct watermelon mosaic virus identified from ginseng (Panax ginseng) transcriptome. AB - Watermelon mosaic virus (WMV) is a member of the genus Potyvirus, which is the largest genus of plant viruses. WMV is a significant pathogen of crop plants, including Cucurbitaceae species. A WMV strain, designated as WMV-Pg, was identified in transcriptome data collected from ginseng (Panax ginseng) root. WMV Pg showed 84% nucleotide sequence identity and 91% amino acid sequence identity with its closest related virus, WMV-Fr. A phylogenetic analysis of WMV-Pg with other WMVs and soybean mosaic viruses (SMVs) indicated that WMV-Pg is a distinct subtype of the WMV/SMV group of the genus Potyvirus in the family Potyviridae. PMID- 29186966 TI - First report of bovine herpesvirus 1 isolation from bull semen samples in China. AB - Bovine herpesvirus 1 (BoHV-1) infection causes substantial economic losses to the cattle industry worldwide. So far, the isolation of BoHV-1 field virus has not been reported in China. Here, for the first time we report that two isolates of BoHV-1 designated as NJ16-1 and NJ16-2 were obtained from semen samples from breeding bulls in China. Typical cytopathic effect in MDBK cells, detection of viral protein VP16 in western blot analysis, PCR detection of BoHV-1 gB gene proved BoHV-1 infection and subsequent nucleotide sequence analysis showed a 99% identity with BoHV-1 Cooper strain. These results suggest that these isolated viruses are BoHV-1. PMID- 29186967 TI - Calcium signaling involved in bovine herpesvirus 1 replication in MDBK cells. AB - Calcium is one of the most prominent second messengers in eukaryotic cells. The involvement of calcium signaling in bovine herpesvirus 1 (BoHV-1) replication was not yet reported. In this study, we revealed that the L-type Ca2+ calcium channel blocker, Verapamil and store-operated calcium channel blocker, 2-aminoethyl diphenylborinate (2-APB) inhibited BoHV-1 replication in MDBK cells at the post entry stages, and the Na+/Ca2+ exchanger inhibitor, N-arachidonoyl glycine exchanger (NAGly) interfered with the viral entry process. NAGly also effected the phosphorylation of PLCgamma-1 at Ser1248, which corroborated our previous findings, that PLCgamma-1 is important for BoHV-1 entry. Collectively, these results suggest that diverse calcium channels are employed by BoHV-1 for efficient replication. PMID- 29186968 TI - Tracking the potyviral P1 protein in Nicotiana benthamiana plants during plum pox virus infection. AB - The P1 protein is derived from the N terminus of potyvirus-coded polyprotein. In addition to the proteolytic activity essential for its maturation, it probably participates in suppression of host defense and/or in virus replication. Clear validation of the P1 in vivo function(s), however, is not yet available. We applied an infectious cDNA clone of plum pox virus (PPV), where the P1 was N fused with a hexahistidine tag, to trace this protein in Nicotiana benthamiana plants during the PPV infection. Immunoblot analysis with the anti-his antibody showed a diffuse band corresponding to the molecular weight about 70-80 kDa (about twice larger than expected) in the root samples from early stage of infection. This signal culminated on the sixth day post inoculation, later it rapidly disappeared. Sample denaturation by boiling in SDS before centrifugal clarification was essential, indicating strong affinity of P1-his to some plant compound sedimenting with the tissue and cell debris. PMID- 29186969 TI - Neuronal and astrocytic involvement in striped dolphins (Stenella coeruleoalba) with morbilliviral encephalitis. AB - Dolphin morbillivirus (DMV), a highly pathogenic agent, may cause peculiar, "brain-only" forms of infection (BOFDI), in which viral antigen and/or genome is found exclusively in the brain from striped dolphins (Stenella coeruleoalba). These BOFDIs show morphopathological similarities with subacute sclerosing panencephalitis and old dog encephalitis (ODE) in measles virus-infected patients and in canine distemper virus-infected dogs, respectively. The brain tissue from 3 BOFDI-affected striped dolphins was investigated by means of double labelling indirect immunofluorescence (DL-IIF) and ultrastructurally, in order to characterize the DMV-targeted neuronal and non-neuronal cell populations, along with the associated submicroscopic findings. Viral colonization of calbindin immunoreactive (IR) and nitric oxide synthase-IR neurons was detected in the cerebral parenchyma from the 3 DMV-infected dolphins under study, associated with nuclear (chromatin) and cytoplasmic (mitochondrial) ultrastructural changes. Furthermore, a limited viral targeting of brain astrocytes was found in these animals, all of which exhibited a prominent astrogliosis/astrocytosis. To the best of our knowledge, those herein reported should be the first submicroscopic pathology and neuropathogenetic data about BOFDI in striped dolphins. In this respect, the marked astrogliosis/astrocytosis and the low viral colonization of brain astrocytes in the 3 DMV-infected dolphins under investigation are of interest from the comparative pathology and viral neuropathogenesis standpoints, when compared with ODE-affected dogs, in whose brain a non-cytolytic, astrocyte to-astrocyte infectious spread has been recently documented. Further studies aimed at characterizing the complex DMV-host interactions in BOFDI-affected striped dolphins are needed. PMID- 29186970 TI - First report of Hosta virus X infecting hosta plants in Ukraine. AB - In September 2011, the leaf samples of hosta cultivar 'Sum and substance' were collected from the collection of Gryshko' National Botanical Garden in Kyiv. The leaves showed dark green streaking and puckering along the leaf veins. Transmission electron microscopy revealed the presence of filamentous viral particles 13 nm in diameter and 470-580 nm in length. Reverse transcription PCR (RT-PCR) analysis confirmed the presence of Hosta virus X (HVX). The sequencing of the complete genome revealed 99% identity to HVX-37 and 97.5% identity to HVX Kr. Notably, ORF4 initiation codon presented a non-conventional start codon (UUG) like it was previously identified in HVX-37. PMID- 29186971 TI - Reactive Oxygen Species and Oncoprotein Signaling-A Dangerous Liaison. AB - SIGNIFICANCE: There is evidence to implicate reactive oxygen species (ROS) in tumorigenesis and its progression. This has been associated with the interplay between ROS and oncoproteins, resulting in enhanced cellular proliferation and survival. Recent Advances: To date, studies have investigated specific contributions of the crosstalk between ROS and signaling networks in cancer initiation and progression. These investigations have challenged the established dogma of ROS as agents of cell death by demonstrating a secondary function that fuels cell proliferation and survival. Studies have thus identified (onco)proteins (Bcl-2, STAT3/5, RAS, Rac1, and Myc) in manipulating ROS level as well as exploiting an altered redox environment to create a milieu conducive for cancer formation and progression. CRITICAL ISSUES: Despite these advances, drug resistance and its association with an altered redox metabolism continue to pose a challenge at the mechanistic and clinical levels. Therefore, identifying specific signatures, altered protein expressions, and modifications as well as protein-protein interplay/function could not only enhance our understanding of the redox networks during cancer initiation and progression but will also provide novel targets for designing specific therapeutic strategies. FUTURE DIRECTIONS: Not only a heightened realization is required to unravel various gene/protein networks associated with cancer formation and progression, particularly from the redox standpoint, but there is also a need for developing more sensitive tools for assessing cancer redox metabolism in clinical settings. This review attempts to summarize our current knowledge of the crosstalk between oncoproteins and ROS in promoting cancer cell survival and proliferation and treatment strategies employed against these oncoproteins.

AB - Chronic obstructive pulmonary disease (COPD) has been described as a systemic disease. Sarcopenia is one of the systemic effects that is related to several adverse outcomes. The objectives of this study were to estimate the prevalence of sarcopenia and to determine the factors associated with sarcopenia in COPD patients in Southeast Asia. This was a cross-sectional study of COPD patients who attended a COPD clinic from May 2015 to December 2016. Baseline characteristics were collected and dual-energy X-ray absorptiometry was used to measure skeletal muscle mass. Handgrip strength was used to assess muscle strength, and as a measurement of physical performance, the 6-min walk distance was used. One hundred and twenty-one participants were recruited. Most of them were men (92.6%). Prevalence of sarcopenia was 24% (29 cases). Independent factors associated with sarcopenia were age >= 75 years (adjusted odds ratio (AOR) 13.3, severity of COPD (AOR 19.2 and 13.4 for moderate and severe COPD), Modified Medical Research Council (MMRC) scale (AOD 1.9), and obesity (AOR 0.04). Sarcopenia affects about one-quarter of COPD patients. Age, severity of COPD, MMRC scale, and BMI status were the factors associated with sarcopenia.

PMID- 29186975 TI - Mammalian Sulfur Amino Acid Metabolism: A Nexus Between Redox Regulation, Nutrition, Epigenetics, and Detoxification. AB - SIGNIFICANCE: Transsulfuration allows conversion of methionine into cysteine using homocysteine (Hcy) as an intermediate. This pathway produces S adenosylmethionine (AdoMet), a key metabolite for cell function, and provides 50% of the cysteine needed for hepatic glutathione synthesis. The route requires the intake of essential nutrients (e.g., methionine and vitamins) and is regulated by their availability. Transsulfuration presents multiple interconnections with epigenetics, adenosine triphosphate (ATP), and glutathione synthesis, polyol and pentose phosphate pathways, and detoxification that rely mostly in the exchange of substrates or products. Major hepatic diseases, rare diseases, and sensorineural disorders, among others that concur with oxidative stress, present impaired transsulfuration. Recent Advances: In contrast to the classical view, a nuclear branch of the pathway, potentiated under oxidative stress, is emerging. Several transsulfuration proteins regulate gene expression, suggesting moonlighting activities. In addition, abnormalities in Hcy metabolism link nutrition and hearing loss. CRITICAL ISSUES: Knowledge about the crossregulation between pathways is mostly limited to the hepatic availability/removal of substrates and inhibitors. However, advances regarding protein-protein interactions involving oncogenes, identification of several post-translational modifications (PTMs), and putative moonlighting activities expand the potential impact of transsulfuration beyond methylations and Hcy. FUTURE DIRECTIONS: Increasing the knowledge on transsulfuration outside the liver, understanding the protein-protein interaction networks involving these enzymes, the functional role of their PTMs, or the mechanisms controlling their nucleocytoplasmic shuttling may provide further insights into the pathophysiological implications of this pathway, allowing design of new therapeutic interventions.

AB - OBJECTIVE: To explore the effect of exercise on cognition in depression as well as the impact of potential moderators and intervention type. METHOD: Controlled and uncontrolled interventional studies that described an exercise intervention and cognitive outcomes in participants with major depressive disorder (MDD) were included following a search of Pubmed, Ovid Medline, PsycInfo and Embase from inception to January 2017. Meta-analyses were conducted to calculate Hedges' g using a random-effects model. Meta-regression explored the relationships among age, baseline cognition, frequency and duration of exercise, and cognitive outcomes. Subgroup analyses were also conducted according to type and intensity of exercise interventions. RESULTS: Of 12 controlled studies and 3 uncontrolled studies that met inclusion criteria, 9 (642 patients) were included in the meta analysis. No significant effect of exercise was found on global cognition (Hedges' g = 0.08, P = 0.33, I2 = 0%) or on individual cognitive domains. Meta regression analyses failed to find significant relationships among participant age, baseline cognition, number of exercise sessions per wk, duration of exercise per wk, total duration of exercise during the intervention, or improvement in global cognition. Interventions combining physical with cognitive activity significantly improved global cognition ( P = 0.048), whereas low-intensity interventions were also positive ( P = 0.048). CONCLUSIONS: No impact of physical exercise was found on cognition in MDD overall. However, we found that interventions combining physical and cognitive activities had a positive impact, and that lower-intensity interventions, where adherence was improved, also impacted positively. There remains a lack of high-quality data in this population. PMID- 29186976 TI - Effectiveness of Heated Sterile Water vs ResoClear(r) for Prevention of Laparoscopic Lens Fogging in a Randomized Comparative Trial. AB - BACKGROUND: Laparoscopic surgery may be complicated by visual disturbances, including lens fogging. Several techniques have been developed to prevent laparoscopic lens fogging (LLF). We aim to compare the effectiveness of two commonly available techniques in prevention of LLF: heated sterile water in a thermos flask and ResoClear(r) impregnation wipes. MATERIALS AND METHODS: In this single-center prospective randomized study, 50 patients underwent an elective laparoscopic donor nephrectomy and were allocated to either heated sterile water or ResoClear(r) impregnation wipes as the antifogging method. The primary outcome was the number of fogging events during the first 30 minutes of the operation, whereas secondary outcomes were operating time, number of cleaning events because of other causes, cost differences, and assessment of predicting factors for fogging events. RESULTS: In 50 patients, the outcomes were analyzed. The number of fogging events was significantly lower when using heated sterile water (median = 0, interquartile range [IQR]: 0-0) compared to ResoClear(r) (median 1.0, IQR: 0.5-3.0), p < 0.001. There were no significant differences in operating time, number of cleaning events because of other causes, and costs. No predictors of fogging events were found. CONCLUSION: The use of heated sterile water leads to significantly less fogging events than the use of ResoClear(r) impregnation wipes, resulting in an improved continuity of the surgery without differences in operating time and costs. PMID- 29186977 TI - Ictal Rhythmic Alpha Sinusoidal Waves in 3 Cases of Anti-NMDAR Encephalitis. AB - Previous studies have shown that extreme delta brush and high beta/delta power ratio on electroencephalogram are suggestive of anti- N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis. Here we report 3 anti-NMDAR encephalitis patients with ictal rhythmic alpha sinusoidal waves in temporal regions, which suggested electrographic seizures in anti-NMDAR encephalitis and indicated potential for seizure occurrence in the future. Rhythmic alpha sinusoidal waves may be an electrographic feature and helpful in distinguishing anti-NMDAR encephalitis. In addition, extreme delta brush was also observed at 47-50 days after morbidity in 2 of 3 patients.

AB - Type 2 diabetes mellitus (T2DM) is a major risk factor associated with hepatocellular carcinoma (HCC). However, the association of T2DM with liver cirrhosis and therapy response in HCC patients is not clear. Hence, in this study, we have evaluated the influence of T2DM on liver cirrhosis severity of HCC and sorafenib response. HCC patients were divided in two groups: T2DM (n = 20) and non-T2DM (nT2DM; n = 50). We found significantly higher number of patients in T2DM group had decompensated liver disease with Child-Turcotte-Pugh score >= 7. Additionally, 71.4% patients were observed to be sorafenib sensitive in T2DM group which was significantly higher as compared to 30% in nT2DM group. This study has highlighted the predisposition of HCC patients with T2DM toward more severe liver disease who were found to be better respondents of sorafenib. Impact statement We have explored the association of type 2 diabetes mellitus (T2DM) on liver cirrhosis severity along with response toward sorafenib in hepatocellular carcinoma (HCC). Most HCC patients exhibit prior history of liver cirrhosis that results following long span of chronic liver disease. T2DM constitutes as an important risk factor for HCC development which is known to elevate its incidence. Further, sorafenib is the FDA approved therapy for HCC whose therapeutic outcome is not investigated in HCC patients with T2DM till date. This observation-based study has unveiled a positive association between T2DM and severity of liver cirrhosis as well as sorafenib response in HCC as examined in a clinical setting. PMID- 29186979 TI - The need for immune biomarkers for treatment prognosis and response in genitourinary malignancies. AB - Immune biomarkers encompass a wide range of blood-borne and cell-associated molecules whose detection or expression may change in response to an immune therapy. These immune therapies encompass a range of platforms including autologous cellular products, in other words, dendritic cells, prime boost DNA vaccines, chimeric antigen receptor (CAR) T cells and checkpoint inhibitors. The response to checkpoint inhibitors by a particular cancer may not be necessarily associated with a change in a particular immune biomarker; other immune biomarkers are needed to assess their association with treatment response or a change in the biology that can impact on the immunologic milieu. How these potential biomarkers can be incorporated into clinical trial design, and their role in interrogating the immunologic milieu will be discussed.

AB - AIM: To clarify the function of miR-128a on radiotherapy and chemotherapy resistance in laryngeal cancer and explore the possible mechanism. MATERIALS & METHODS: Hep-2 and AMC-HN-8 cell lines were cultured. MiR-128a was upregulated utilizing lentiviral transfection. Through radiotherapy and chemotherapy assays, the function of miR-128a on chemoradiotherapy was evaluated. The correlation of miR-128a with BMI1 was identified by performing real-time PCR. RESULTS: The hsa miR128a cell line was established. The chemotherapy assay revealed that an overexpression of miR-128a decreases the inhibition to chemotherapy. The radiotherapy assay showed that miR-128a promotes the radiotherapy sensitivity. The expression of BMI1 decreased with overexpression of miR-128a. CONCLUSION: miR 128a confers chemoradiotherapy sensitivity of laryngeal cancer cells and targeting BMI1 gene is a possible mechanism of the effect. PMID- 29186981 TI - Oxidative Stress Induces an Interactive Decline in Wnt and Nrf2 Signaling in Degenerating Retinal Pigment Epithelium. AB - AIMS: Cells have evolved a highly sophisticated web of cytoprotective systems to neutralize unwanted oxidative stress, but are challenged by unique modern day stresses such as cigarette smoking and ingestion of a high-fat diet (HFD). Age related disease, such as age-related macular degeneration (AMD), the most common cause of blindness among the elderly in Western societies, develops in part, when oxidative stress overwhelms cytoprotective systems to injure tissue. Since most studies focus on the protection by a single protective system, the aim of this study was to investigate the impact of more than one cytoprotective system against oxidative stress. RESULTS: Wingless (Wnt) and nuclear factor-erythroid 2 related factor 2 (Nrf2), two fundamental signaling systems that are vital to cell survival, decline after mice are exposed to chronic cigarette smoke and HFD, two established AMD risk factors, in a bidirectional feedback loop through phosphorylated glycogen synthase kinase 3 beta. Decreased Wnt and Nrf2 signaling leads to retinal pigment epithelial dysfunction and apoptosis, and a phenotype that is strikingly similar to geographic atrophy (GA), an advanced form of AMD with no effective treatment. INNOVATION: This study is the first to show that chronic oxidative stress from common modern day environmental exposures reduces two fundamental and vital cytoprotective networks in a bidirectional feedback loop, and their decline leads to advanced disease phenotype. CONCLUSION: Our data offer new insights into how combined modern oxidative stresses of cigarette smoking and HFD contribute to GA through an interactive decline in Wnt and Nrf2 signaling. Antioxid.

AB - BACKGROUND: Depression is a common health problem among patients with cancer. The Edmonton Symptom Assessment System (ESAS) is one of many tools that have been used to evaluate depression in these patients. Nevertheless, the diagnostic performance and the appropriate cutoff point of the ESAS for the assessment of depression in these patients have varied in the studies. PURPOSE: To determine the diagnostic accuracy and the optimal cutoff point for the ESAS for the assessment of depression in patients with cancer. DATA SOURCES: PubMed, Scopus, CINAHL, and Cochrane library databases from inception to September 18, 2016. STUDY SELECTION: Paired reviewers independently screened abstracts and full-text articles for all cross-sectional studies published in English and compared these with the ESAS in the depression (ESAS-D) subscale with reference to standard tests for the assessment of depression. DATA EXTRACTION: Two reviewers serially abstracted the data and independently assessed the risk of bias by using the Quality Assessment of Diagnostic Accuracy Studies 2. DATA SYNTHESIS: A total of 6 studies were eligible for review. Our meta-analysis showed the optimal cutoff point of the ESAS-D >= 4, with pooled sensitivity and specificity at 53% (95% confidence interval [CI]: 38%-67%) and 90% (95% CI: 82%-94%), respectively. The positive likelihood ratio and diagnostic odds ratio of the ESAS-D >= 4 were 5.2 (95% CI: 3.1-8.6) and 10 (95% CI: 5-19). There was a high degree of heterogeneity between the studies ( P value <.001, I2 = 96%). CONCLUSION: We suggest that an ESAS-D >= 4 could be used to detect possible cases of depression in patients with cancer. Registration: Our study protocol was registered with the International Prospective Register of Systematic Reviews on October 4, 2016, and was last updated on January 11, 2017 (registration number CRD42016048288). PMID- 29186982 TI - A Randomized Controlled Trial of Strategies to Improve Family Members' Preparedness for Surrogate Decision-Making. AB - OBJECTIVE: To evaluate 2 strategies for preparing family members for surrogate decision-making. DESIGN: A 2 * 2 factorial, randomized controlled trial testing whether: (1) comprehensive online advance care planning (ACP) is superior to basic ACP, and (2) having patients engage in ACP together with family members is superior to ACP done by patients alone. SETTING: Tertiary care centers in Hershey, Pennsylvania, and Boston, Massachusetts. PARTICIPANTS: Dyads of patients with advanced, severe illness (mean age 64; 46% female; 72% white) and family members who would be their surrogate decision-makers (mean age 56; 75% female; 75% white). INTERVENTIONS: Basic ACP: state-approved online advance directive plus brochure. Making Your Wishes Known (MYWK): Comprehensive ACP decision aid including education and values clarification. MEASUREMENTS: Pre-post changes in family member self-efficacy (100-point scale) and postintervention concordance between patients and family members using clinical vignettes. RESULTS: A total 285 dyads enrolled; 267 patients and 267 family members completed measures. Baseline self-efficacy in both MYWK and basic ACP groups was high (90.2 and 90.1, respectively), and increased postintervention to 92.1 for MYWK ( P = .13) and 93.3 for basic ACP ( P = .004), with no between-group difference. Baseline self efficacy in alone and together groups was also high (90.2 and 90.1, respectively), and increased to 92.6 for alone ( P = .03) and 92.8 for together ( P = .03), with no between-group difference. Overall adjusted concordance was higher in MYWK compared to basic ACP (85.2% vs 79.7%; P = .032), with no between group difference. CONCLUSION: The disconnect between confidence and performance raises questions about how to prepare family members to be surrogate decision makers. PMID- 29186985 TI - Psychometric Properties of the Perceived Wellness Culture and Environment Support Scale. AB - OBJECTIVE: This study reports on the psychometric properties of the 11-item Perceived Wellness Culture and Environment Support Scale (PWCESS) and its relationship with employee healthy lifestyle beliefs and behaviors. METHODS: Faculty and staff (N = 3959) at a large public university in the United States mid-west completed the PWCESS along with healthy lifestyle beliefs and behaviors scales. Data were randomly split into 2 halves to explore the PWCESS' validity and reliability and the second half to confirm findings. RESULTS: Principal components analysis indicated a unidimensional construct. The PWCESS was positively related to healthy lifestyle beliefs and behaviors supporting the scale's validity. Confirmatory factor analysis supported the unidimensional construct (Cronbach's alpha = .92). CONCLUSION: Strong evidence supports the validity and reliability of the PWCESS. Future use of this scale could guide workplace intervention strategies to improve organizational wellness culture and employee health outcomes. PMID- 29186984 TI - Healthy Immigrant Families: Randomized Controlled Trial of a Family-Based Nutrition and Physical Activity Intervention. AB - PURPOSE: To evaluate a healthy eating and physical activity intervention for immigrant families, derived through community-based participatory research. DESIGN: The Healthy Immigrant Families study was a randomized controlled trial with delayed intervention control group, with families as the randomization unit. SETTING: US Midwest city. PARTICIPANTS: Participants were recruited by community partners from Hispanic, Somali, and Sudanese immigrant communities. INTERVENTION: Family health promoters from participating communities delivered 6 healthy eating modules, 4 physical activity modules, and 2 modules synthesizing information in 12 home visits (60-90 minutes) within the first 6 months. Up to 12 follow-up phone calls to each participant occurred within the second 6 months. MEASURES: Primary measures were dietary quality measured with weekday 24-hour recall and reported as Healthy Eating Index score (0-100) and physical activity measured with accelerometers (14 wear days) at baseline, 6, 12, and 24 months. RESULTS: In total, 151 persons (81 adolescents and 70 adults; 44 families) were randomly assigned. At 12 months, significant improvement occurred in Healthy Eating Index scores for adults in the intervention group compared with controls (change, +8.6 vs -4.4; P < .01) and persisted at 24 months (+7.4 from baseline; P < .01). No differences were observed for adolescents and no significant differences occurred between groups for physical activity. CONCLUSION: This intervention produced sustained dietary quality improvement among adults but not among adolescents. Program outcomes are relevant to communities working to decrease cardiovascular risk among immigrant populations. PMID- 29186986 TI - Steroid-induced mental disorders in cancer patients: a systematic review. AB - Corticosteroids are a central part of many cancer treatment regimens. Neuropsychiatric toxicity has complicated their use, including an association with a spectrum of symptoms, from insomnia, cognitive impairment and mood symptoms, to severe mental disorders, including mania, psychosis and severe depression. Although steroid-induced mental disorders were first reported in medicine more than 60 years ago, there is a dearth of evidence available to date on optimal treatment and prevention to guide cancer clinicians. We completed a systematic review of the current evidence for therapeutic and prophylactic interventions of steroid-induced mental disorders in cancer. We searched Medline, Embase and PsycINFO and selected studies related to steroid-induced mental disorder. The studies found were limited to case series and case reports only. PMID- 29186987 TI - Perurethral transvesical route for oocytes retrieval: an old technique for a new indication in oncofertility. AB - : We aimed to evaluate the safety and efficiency of the peruretheral transvesical oocyte retrieval in oncofertility. We conducted a retrospective comparative study in our assisted reproductive technologies center. STUDY GROUP: 28 pubertal young women affected by malignancies, referred for fertility preservation and refusing transvaginal (TV) procedure. CONTROL GROUP: 28 infertile patients, aged less than 25 years, who have undergone in vitro fertilization with TV oocyte retrieval. The ovarian stimulation was significantly longer on the study group. There was no difference between the two groups regarding mean number of collected metaphase II oocytes. One patient of the study group had a transient dysuria. These preliminary data suggest that, in oncofertility, peruretheral transvesical oocyte retrieval is an alternative when the TV route is refused or not feasible. PMID- 29186988 TI - Interchangeability of biosimilar and biological reference product: updated regulatory positions and pre- and post-marketing evidence. AB - INTRODUCTION: Since 2006, biosimilars have been available in several countries worldwide, thus allowing for potential savings in pharmaceutical expenditure. However, there have been numerous debates about the interchangeability of biosimilars and reference products based on concerns of immunogenicity by switching between biological products, which may cause lack of effect and toxicity. Areas covered: The authors provide the reader with an overview of the different positions of regulatory authorities on the interchangeability and automatic substitution of biosimilars and reference products. Presently, the FDA allows automatic substitution without prescriber intervention if the biosimilar is interchangeable with reference products, while the European Medicines Agency delegate to each single EU member state. Expert opinion: Different approaches in defining interchangeability and automatic substitution call for harmonization to increase confidence of healthcare professionals and patients about the clinical impact of switching. Networks of electronic healthcare records and administrative databases, potentially linkable to clinical charts and registries may rapidly assess frequency and benefit-risk profile of different switching patterns in routine care at different levels, thus integrating and strengthening pre marketing evidence. PMID- 29186989 TI - Treatment of Distal Ureteral Calculi Using Extracorporeal Physical Vibrational Lithecbole Combined with Tamsulosin: A New Option to Speed Up Obstruction Relief. AB - INTRODUCTION: The obstruction of the urinary tract by calculi at the narrowest anatomical areas leads to impaired drainage and severe pain. The aim of this study was to evaluate a new technology, extracorporeal physical vibrational lithecbole (EPVL) combined with tamsulosin, as a treatment for distal ureteral calculi (DUC). MATERIALS AND METHODS: Between July 2013 and July 2014, 672 patients diagnosed with DUC were randomly divided into three groups; a group receiving EPVL plus 0.4 mg oral tamsulosin daily (PO qd) (experimental group, n = 236), a group receiving 0.4 mg tamsulosin PO qd (n = 222), and a group receiving EPVL only (n = 214) (control groups). RESULTS: There were no significant differences in general characteristics between the three groups. Stone diameters ranged from 0.32 to 1 cm. In the EPVL plus tamsulosin group, 60.1% of patients showed detectable fragment expulsion at 48 hours, and 91.1% were stone free at 7 days. Compared with the two control groups, these rates were significantly higher (EPVL group was 0% and 50.5% and medical expulsive therapy group was 0% and 50.0%, p < 0.05). The stone-free rates were similar in the three groups 2 weeks later (94.5%, 93.6%, and 93.5%; p > 0.05). Patients in the EPVL plus tamsulosin group achieved similar stone-free rates compared with the other two groups, but the speed of the stone expulsion was quicker for both sexes and all age groups (about a week; p < 0.05). CONCLUSION: This indicates that EPVL plus tamsulosin could be used as an effective, but faster treatment option for patients with DUC, alleviating the symptoms of DUC in a shorter period of time. PMID- 29186990 TI - Nanomedicine approaches for sirolimus delivery: a review of pharmaceutical properties and preclinical studies. AB - Sirolimus (rapamycin) is a mammalian target of rapamycin (mTOR) inhibitor with immunosuppressive, antiproliferative, antiangiogenic, antifungal, anti-restenosis and anti-inflammatory properties. However, its clinical application is often hampered by poor aqueous solubility, first-pass metabolism, transport by p glycoprotein efflux pump, limited oral bioavailability and nonspecific distribution in off-target sites. Recently, various formulation strategies have emerged to overcome these limitations. Among these, pharmaceutical nanotechnology with numerous advantages has great potential for sirolimus delivery. Up to now, the only nanoparticle based FDA approved formulation in the market is Rapamune(r) tablet which is composed of drug nanocrystals. This review focuses on recent studies that have been investigated various nanostructured carriers such as liposomes, micelles, polymeric nanoparticles, nanocrystals, magnetic nanoparticles, albumin nanoparticles, solid dispersion nanoparticles and niosomes for sirolimus delivery (in organ transplantation, cancer, vascular restenosis, etc.).

The structures of compounds were established on the basis of extensive spectroscopic data. PMID- 29186992 TI - Evaluation of the Southern Harm Reduction Coalition for HIV Prevention: Advocacy Accomplishments. AB - BACKGROUND: HIV/AIDS rates are higher in the Southern United States compared to other regions of the country. Reasons for disparities include poverty, health care access, and racism. People who inject drugs (PWID) account for 8% of HIV/AIDS incidence rates. Harm reduction can connect PWID to needed resources. AIDS United Southern REACH grantees developed the Southern Harm Reduction Coalition (SHRC) as a means to decrease HIV/AIDS and viral hepatitis rates, criminalization of drug users and sex workers, and drug overdose. METHOD: Investigators used an intrinsic case study design to examine the context of harm reduction in the Southern United States, successful strategies, and outcomes. Data collection included key informant interviews and coalition documents. The community coalition action theory was used to examine the data. RESULTS: The SHRC initiated regional conferences and customized trainings. Strengths-based language and utilization of diverse strengths among coalition members were used to effect change. Coalition outcomes included syringe decriminalization legislation, syringe exchange, naloxone access, naloxone funding legislation, and 911 Good Samaritan laws, along with expanded support for PWID. CONCLUSIONS: Advocacy successes can be applied to similar organizations in the Southern United States to promote harm reduction and potentially decrease HIV/AIDS burden, viral hepatitis, criminalization, and overdose. PMID- 29186993 TI - Medication use in adults with attention deficit/hyperactivity disorder in a commercially-insured population in the United States. AB - OBJECTIVE: To examine real-world prescription medication usage among commercially insured adults with attention deficit/hyperactivity disorder (ADHD) in the US. METHODS: Adults with ADHD who received >=1 ADHD medication during 2013 were identified from a large US claims database. Combination therapy was defined as an overlap of >=30 days between the index (first treatment >=30 days in 2013) and another medication(s). Patients were classified into six groups: long-acting (LA) monotherapy, short-acting (SA) monotherapy, LA + LA, SA + SA, LA + SA, and >2 therapies. Analyses compared baseline characteristics by regimen, ranked combination regimens, and estimated daily average consumption (DACON) for monotherapy users. RESULTS: Of 206,443 adults with ADHD (mean age = 32.9 years; 51.6% female), 56.9% used LA monotherapy, 30.7% SA monotherapy, and 12.5% used combination therapies (LA + SA: 10.3%; LA + LA: 1.3%; SA + SA: 0.4%; >2 therapies: 0.5%). Extended-release mixed amphetamine salts (MAS-XR, 39.2%) and lisdexamfetamine (LDX, 31.5%) were the most common LA monotherapies. Nearly all SA monotherapy patients received immediate-release mixed amphetamine salts (MAS IR; 81.7%). The top three therapies among combination categories were: (a) LA + LA: branded MAS-XR + generic MAS-XR (13.7%), LDX + generic MAS-XR (10.8%), LDX + guanfacine ER (10.7%); (b) SA + SA: generic MAS-IR + clonidine IR (33.5%), generic MAS-IR + generic MPH SA (17.9%), branded MAS-IR + generic MAS-IR (11.1%); (c) LA + SA: generic MAS-XR+/-IR (39.2%), LDX + generic MAS-IR (16.7%), LA + SA generic MPH (12.6%). Among monotherapy users, DACON was 1.2 +/- 0.6 (LA) and 2.1 +/- 0.9 (SA) tablets. CONCLUSIONS: There is significant treatment heterogeneity among US adults with ADHD. A sizable proportion of patients received monotherapies at above the recommended dosages or combination therapies, suggesting existing single-tablet regimens may not meet patients' needs.

PMID- 29186994 TI - Supersonic shear imaging for the diagnosis of liver fibrosis and portal hypertension in liver diseases: a meta-analysis. AB - BACKGROUND AND AIMS: The meta-analysis aimed to summarize the technical success rate of supersonic shear imaging (SSI) and to evaluate the diagnostic performance of liver and spleen stiffness measurement (LSM and SSM) with SSI for the detection of liver fibrosis, portal hypertension, and gastroesophageal varices in liver diseases. METHODS: PubMed, EMBASE, and Cochrane Library databases were searched. Technical success rate of SSI was pooled. Area under curve (AUC), sensitivity, and specificity with corresponding 95% confidence interval (CI) were calculated. RESULTS: Included studies regarding the diagnostic performance of SSI for liver fibrosis, portal hypertension, and esophageal varices numbered 28, 4, and 4 respectively. The pooled technical success rates of LSM and SSM were 95.3% and 75.5%, respectively. The AUC, sensitivity, and specificity of LSM/SSM for different stages of liver fibrosis were 0.85-0.94, 0.7-0.89, and 0.82-0.92, respectively. The AUC, sensitivity, and specificity of LSM were 0.84 (95%CI = 0.8 0.86), 0.79 (95%CI = 0.7-0.85), and 0.82 (95%CI = 0.72-0.88) for clinically significant portal hypertension, 0.85 (95%CI = 0.82-0.88), 0.8 (95%CI = 0.68 0.88), and 0.8 (95%CI = 0.6-0.92) for any varices, and 0.86 (95%CI = 0.83-0.89), 0.86 (95%CI = 0.76-0.92), and 0.61 (95%CI = 0.35-0.83) for high-risk varices, respectively. CONCLUSIONS: LSM with SSI had a high diagnostic accuracy for liver fibrosis, but a moderate diagnostic accuracy for portal hypertension and esophageal varices. PMID- 29186996 TI - An assessment of innovative pricing schemes for the communication of value: is price discrimination and two-part pricing a way forward? AB - INTRODUCTION: With the introduction of new expensive medicines, traditional pricing schemes based on constructs such as price per pill/vial have been challenged. Potential innovative schemes could be either financial-based or performance-based. Within financial-based schemes the use of price discrimination is an emerging option, which we explore in this assessment. Areas covered: In the short term the price per indication approach is likely to become more prevalent for high cost, high benefit new pharmaceuticals, such as those emerging in oncology (e.g. new combination immunotherapies). 'Two-Part Pricing' (2PP) is a frequently used payment method in other industries, which consists of an Entry Fee, giving the buyer the right to use the product, and a Usage Price charged every time the product is purchased. Introducing 2PP into biopharma could have cross-stakeholder benefits including broader patient access, and improvement in budget/revenue predictability. A concern however is the potential complexity of the negotiation between manufacturer and payer. Expert commentary: We believe 'price discrimination' and 2PP in particular can be relevant for some new, expensive specialist medicines. A recommended first step would be to initiate pilots to test to what degree the 2PP approach meets stakeholder objectives and is practical to implement within specialty care. PMID- 29186997 TI - Western diets are not responsible for chronic acid retention: a critical analysis of organic acid and phosphate contribution. AB - According to usual literature, the diet-dependent endogenous production of titratable acidity (TA) is contributed by sulphuric and phosphoric acids (NA) and by metabolizable acids (MAs), representing 'net-endogenous acid production' (NEAP). NEAP is mainly neutralised by diet-dependent [Formula: see text] salts of inorganic cations ([Formula: see text]), estimated in foods, faeces and urine from inorganic cation-anion difference (NB). It is claimed that urinary loss of organic acids' anions, '[Formula: see text]', induces metabolizable H+ ions' retention. Since '[Formula: see text]' is normally lost in urine as '[Formula: see text]' or '[Formula: see text]', no MA retention takes place. Therefore, in our approach, net acid production (NAP) reduces to endogenous sulphuric acidity only. Since in western diets (WDs) alkaline cations exceed inorganic anions (NB excess), acid excess from phosphorus is neutralized. Moreover, the renal reabsorption of ultra-filtered Pi takes place at [Formula: see text] ratios greater than '4/1', which means that the kidney operates as a dietary Pi dependent NB generator ([Formula: see text] or [Formula: see text]). Since, in standard WDs, H2SO4 generation is less than '[Formula: see text]' production, the sulphuric acidity escaping the intestinal [Formula: see text] absorption is neutralized by [Formula: see text] and excreted as diet-dependent [Formula: see text], without interfering in normal A/B status. Only when extreme acidifying diets are ingested, sulphuric acidity may exceed '[Formula: see text]'. In this case, the excess of sulphuric acidity production is neutralised by the intervention of urinary [Formula: see text] excretion, whose employment is normally restricted to prevent loss of ultra-filtered NB. Finally, the whole body NA balance (NAb(W)) is calculated from the difference 'NAabs - NA(u)', where abs = intestinal absorption and u = urinary excretion. Being 'NAabs ~ NA(u)', NAb(W) approximates zero, confirming WDs as non-acidifying foods. PMID- 29186998 TI - Hydrothermal grain pre-processing and ultra-fine milling for the production of durum wheat flour fractions with high nutritional value. AB - This work describes a process for producing durum wheat flour fractions with high potential nutritional value using grain pre-milling hydrothermal treatment and ultra-fine grinding (micronization), coupled with air classification. The difference of bioactive value of the flour fractions in relation to dietary fibre and phenolic compounds was monitored on four durum wheat cultivars by analysing total arabinoxylans, water extractable arabinoxylans and 5- n-alkylresorcinols. The extractability of the analysed compounds was most significantly affected by hydrothermal treatment. On average, the hydrothermally treated kernels compared with the untreated ones presented a marked increase of water extractable arabinoxylans and alkylresorcinols (about 25 and 48%, respectively), whereas slightly lower total arabinoxylans content (about 9%) was detected. The air classification applied on micronized kernels produced two flour fractions, coarse and fine, with the last showing, irrespective of the hydrothermal treatment, an increment of alkylresorcinols (24 and 22% in untreated and treated samples) and of total arabinoxylans (13 and 20% in untreated and treated samples) in comparison with the coarse one. The fine fraction (particles <= 120 um), resulting richer in bioactive compounds, provides an interesting raw material to enrich traditional semolina in which, due to the removal of the external layers, the losses of total arabinoxylans and of alkylresorcinols were more than 60 and 90% alkylresorcinols, respectively, if compared with whole wheat grain. PMID- 29186999 TI - Dosing strategies to optimize currently available anti-MRSA treatment options (Part 2: PO options). AB - INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA) is a problematic pathogen in both outpatient and inpatient settings. Research to optimize the dosing of these agents is needed to slow the development of antimicrobial resistance and to decrease the likelihood of clinical failure. Areas covered: This review summarizes the available data for orally administered antimicrobials routinely used as monotherapy for MRSA infections. We make recommendations and highlight the current gaps in the literature. A PubMed (1966 - Present) search was performed to identify relevant literature for this review. Expert commentary: There is a vast divide in the amount of pharmacokinetic/pharmacodynamic data to guide dosing decisions for older MRSA agents compared with the oxazolidenones. Five-year view: Additional retrospective data will become available for the older MRSA agents in severe MRSA infections. PMID- 29187000 TI - Does myo-inositol oxygenase, the only enzyme to catalyze myo-inositol in vivo, play a role in the etiology of polycystic ovarian syndrome? AB - In polycystic ovary syndrome (PCOS), myo-inositol (MI) supplements have shown many beneficial effects. In this study, therefore, we aimed to investigate the serum level of myo-inositol oxygenase (MIOX), which is the only enzyme catalyzing MI in vivo, in patients with PCOS. Serum MIOX enzyme levels and other laboratory parameters were compared between sixty patients, who were diagnosed with PCOS for the first time, and sixty healthy individuals at similar age and sex. MIOX serum levels were not different between two groups (p = 0.7428). MIOX median and 95% CI were 19.4 and 10.6-39.1 in the control group and 16.4 and 7.6-46.2 in the patient group respectively. Demographic data, biochemical and hematological parameters, hormone parameters were not different except from the lymphocyte count between the two groups. Lymphocyte count was higher in the patient group. Although the ratio of LH/FSH was higher in the patient group, it was not statistically significant. Our results suggest that serum MIOX levels do not change in PCOS. It was, therefore, concluded that MI deficiency observed in PCOS was not related to the level of MIOX enzyme which cleaves MI. PMID- 29187001 TI - The Utility of Physical Activity Micro-Grants: The ParticipACTION Teen Challenge Program. AB - Youth physical activity levels remain low in Canada and worldwide. Lack of environmental resources (e.g., access to equipment and facilities, transportation options, and participation costs) is a key barrier for youth participation. Micro grants are small budgets of money awarded via grant applications and may help community organizations facilitate youth physical activity participation by alleviating environmental resource barriers. ParticipACTION Teen Challenge was a national micro-grant scheme administered in Canada. Secondary analysis of survey data from Provincial and Territorial coordinators, registered community organizers, and successful grant applicants were used to evaluate the process and outcomes of Teen Challenge. Results showed that the financial subsidy of 500CAD was used mainly toward equipment, instruction, and transportation. Coordinators and community organizers indicated high levels of satisfaction and benefits for communities and teens. A key benefit for coordinators was leveraging the Teen Challenge network for physical activity promotion. Reported benefits for teenaged participants included leadership opportunities (e.g., helping create and implement programs) and increased physical activity participation. Findings highlight the value of micro-grants for supporting sport and physical activity opportunities for Canadian teens, and show that such schemes address barriers related to environmental resources. The sustainability of micro-grant schemes remains to be seen. PMID- 29187002 TI - The influence of a diet based on flaxseed, an omega-3 source, during different developmental periods, on the blood pressure of rats submitted to stress. AB - OBJECTIVE: This study aimed to investigate a flaxseed diet during different developmental periods, and its effect on the blood pressure of rats submitted to stress. METHODS: Fifty-six male rats (F1), born from 14 rats (F0), were divided into seven groups (n = 8): flaxseed group (FG); flaxseed group gestation and lactation (FG-GL); flaxseed group weaning (FG-W); flaxseed group weaning and stress (FG-WS); flaxseed group stress (FG-S); flaxseed group gestation lactation and weaning (FG-GLW), and control Group (CG). Stress protocol was undertaken for 1 month. Blood pressure was analysed before and after the stress protocol. The left adrenal glands and serum corticosterone levels were analysed. RESULTS: Systolic blood pressure before stress was lower in all groups with flaxseed diet compared with the CG (p = .00001). After stress, CG showed higher blood pressure compared with FG, FG-GL, and FG-GLW (p = .004). The levels of corticosterone were lower in the FG between all groups (p < .000001) and the CG showed higher compared with FG-W, FG-WS, FG-GL, and FG-GLW (p < .0001). The adrenal gland did not show differences. CONCLUSIONS: Results suggest a possible factor from a flaxseed diet against the effects of stress on a blood pressure in all periods of life but especially in the gestation and lactation periods.

PMID- 29187003 TI - The effects of chronic testosterone administration on hypothalamic gonadotropin releasing hormone regulatory factors (Kiss1, NKB, pDyn and RFRP) and their receptors in female rats. AB - The effects of androgens on gonadotropin-releasing hormone (GnRH) secretion in females have not been fully established. To clarify the direct effects of androgens on hypothalamic reproductive factors, we evaluated the effects of chronic testosterone administration on hypothalamic GnRH regulatory factors in ovariectomized (OVX) female rats. Both testosterone and estradiol reduced the serum luteinizing hormone levels of OVX female rats, indicating that, as has been found for estrogen, testosterone suppresses GnRH secretion via negative feedback. Similarly, the administration of testosterone or estradiol suppressed the hypothalamic mRNA levels of kisspeptin and neurokinin B, both of which are positive regulators of GnRH, whereas it did not affect the hypothalamic mRNA levels of the kisspeptin receptor or neurokinin-3 receptor. On the contrary, the administration of testosterone, but not estradiol, suppressed the hypothalamic mRNA expression of prodynorphin, which is a negative regulator of GnRH. The administration of testosterone did not alter the rats' serum estradiol levels, indicating that testosterone's effects on hypothalamic factors might be induced by its androgenic activity. These findings suggest that as well as estrogen, androgens have negative feedback effects on GnRH in females and that the underlying mechanisms responsible for these effects are similar, but do not completely correspond, to the mechanisms underlying the effects of estrogen on GnRH.

AB - The present research was to investigate the effects of skimmianine (SK) in four non-small cell lung cancer (NSCLC) cells. We found that SK can significantly inhibit the growth of NSCLC cells and markedly induce apoptosis in NSCLC cells. The effects of growth inhibition and apoptosis induction were in a concentration response relationship and caspase-dependent manner. PMID- 29187006 TI - Double tinnitus in a single ear. AB - OBJECTIVE: To search for distinctive clinical features of patients with double tinnitus in a single ear. Design retrospective: Study sample: Six hundred and fourteen tinnitus patients were interviewed using a detailed questionnaire. They underwent thorough audiological evaluation. Records of seven patients reporting double tinnitus in 10 ears were identified and analysed. There were three women and four men in the group (mean age 40, range 29-49 years). RESULTS: All but two individuals declared sudden onset of the complaints. Three patients had been diagnosed with sudden sensorineural hearing loss. In all the patients, the components of double tinnitus were compared both to a pure tone and to a narrow band noise. The sounds were considered by the patients to be primary (more prominent) or secondary. All but one patient declared hypersensitivity to loud sounds. Vertigo was present in only two of the double tinnitus sufferers. Abnormal DPOAEs frequency values and audiogram notch frequencies were closer to the primary than the secondary tinnitus matches. CONCLUSIONS: In our study, double tinnitus was rare, mostly perceived by patients with a sudden onset of tinnitus. This is the first report presenting audiological findings in patients with double tinnitus in a single ear. Prospective search of cohorts of tinnitus sufferers for such patients and functional neuroimaging of their auditory pathways for determining underlying mechanisms of the complaints is advocated. PMID- 29187008 TI - Cost-effectiveness analysis of the use of high-flow oxygen through nasal cannula in intensive care units in NHS England. AB - OBJECTIVE: To estimate the cost-effectiveness of Nasal High Flow (NHF) in the intensive care unit (ICU) compared with standard oxygen or non-invasive ventilation (NIV) from a UK NHS perspective. METHODS: Three cost-effectiveness models were developed to reflect scenarios of NHF use: first-line therapy (pre intubation model); post-extubation in low-risk, and high-risk patients. All models used randomized control trial data on the incidence of intubation/re intubation, events leading to intubation/re-intubation, mortality and complications. NHS reference costs were primarily used. Sensitivity analyses were conducted. RESULTS: When used as first-line therapy, OptiflowTM NHF gives an estimated cost-saving of L469 per patient compared with standard oxygen and L611 versus NIV. NHF cost-savings for high severity sub-group were L727 versus standard oxygen, and L1,011 versus NIV. For low-risk post-intubation patients, NHF generates estimated cost-saving of L156 versus standard oxygen. NHF decreases the number of re-intubations required in these scenarios. Results were robust in most sensitivity analyses. For high-risk post-intubation patients, NHF cost savings were L104 versus NIV. NHF results in a non-significant increase in re intubations required. However, reduction in respiratory failure offsets this. CONCLUSIONS: For patients in ICU who are at risk of intubation or re-intubation, NHF cannula is likely to be cost-saving. PMID- 29187007 TI - Glecaprevir + pibrentasvir (ABT493 + ABT-530) for the treatment of Hepatitis C. AB - INTRODUCTION: Glecaprevir (formerly ABT-493, pangenotypic NS3/4A protease inhibitor) and pibrentasvir (formerly ABT-530, pangenotypic NS5A inhibitor) are second generation direct acting antivirals (DAA) for the treatment of chronic Hepatitis C (HCV). It is a fixed dose ribavirin (RBV)-free regimen with activity against genotypes (GT) 1-6. In vitro the two antivirals have synergistic activity with a high barrier to resistance and potent activity against common polymorphisms. It is once daily oral dosing with minimal absorption, primary biliary excretion, and negligible renal excretion, making it safe for patients with renal impairment. This regimen is being reviewed because it is the first pangenotypic regimen suitable for those with renal impairment and prior DAA failure. Areas covered: The key phase 2 and 3 trials which investigated the efficacy and safety of glecaprevir/pibrentasvir are reviewed by methodology, primary end point, baseline demographic data, response rates, and adverse events. Literature search methodology involved reviewing key abstracts presented at the American Association for the Study of Liver Disease and European Association for the Study of Liver. Expert commentary: The advantages and limitations of glecaprevir/pibrentasvir will be reviewed in comparison to its competitor drug on the market. PMID- 29187009 TI - Ixekizumab: an anti- IL-17A monoclonal antibody for the treatment of psoriatic arthritis. AB - INTRODUCTION: Psoriatic arthritis (PsA) is an inflammatory rheumatic disease that manifests itself with synovitis, dactylitis, enthesitis and also axial involvement. Interleukin-17A has been identified as a master cytokine in the inflammatory response and pathogenesis of PsA and spondyloarthritis in general. Ixekizumab is a new humanized monoclonal antibody that blocks the biological activity of IL-17A. This biological agent has previously demonstrated a high level of efficacy in psoriasis. Areas covered: This review discusses the basic immunology of the IL-17 cytokine family, the contribution of IL-17A to the immunopathogenesis of PsA, the clinical trials that evaluated ixekizumab in patients with PsA (SPIRIT program) and the safety of this agent. Expert opinion: Ixekizumab demonstrated its efficacy in different aspects of PsA including peripheral joint involvement, dactylitis, skin symptoms and patient reported outcomes in the 2 phase III trials from the SPIRIT program. Its safety profile was consistent with previous observations in patients with psoriasis. The role of IL-17A in the management of patients with PsA needs further clarification. According to EULAR recommendations for the management of PsA, IL-17A inhibitors may be used as second line biological DMARDs after TNF inhibitors. PMID- 29187011 TI - Noncardiovascular Disease and Critical Care Delivery in a Contemporary Cardiac and Medical Intensive Care Unit. AB - BACKGROUND: Noncardiovascular comorbidities and critical illness are increasing in cardiovascular intensive care units (CICUs). There are limited data comparing critical care delivery, resource utilization, and costs between contemporary CICUs and medical intensive care units (MICUs). METHODS: All CICU (n = 6967; 22 748 patient-days) and MICU (n = 10 892; 39 211 patient-days) admissions to Cedars Sinai Medical Center, a tertiary care academic medical center, between January 2011 and December 2016 were reviewed. Both the CICU and MICU admitted patients for primary cardiovascular or medical conditions during the study period, but not for postoperative surgical care. RESULTS: Patients admitted to the CICU were more frequently older, male, and had more preexisting cardiac disease ( P < .0001). More than one-fifth (21.4%) of CICU patients had a noncardiovascular primary admission diagnosis, compared to 89.2% of MICU patients. Cardiovascular intensive care unit patients had lower Acute Physiology and Chronic Health Evaluation III scores (51.1 [19.9] vs 61.1 [24.9], P < .0001) and shorter median hospital length of stay ( P < .001), but not in-unit stay, as compared to MICU patients. Mechanical ventilation, vasopressors, inotropes, renal replacement therapy, and/or blood transfusion were required in 35.0% of CICU patients compared with 62.2% of MICU patients ( P < .0001). The unit mortality rate was lower for CICU than MICU patients (4.8% vs 13.0%, P < .0001), as was the hospital mortality rate (9.3% vs 21.6%, P < .0001). The standardized mortality ratio was 0.73 for the CICU and 0.86 for the MICU. There was no difference in the mean direct cost of care per patient-day between the CICU and MICU ($4011 USD [376] vs $3990 USD [214], P = .77). CONCLUSIONS: The burden of noncardiovascular diseases and the requirement for critical care therapies are high in contemporary CICU patients but remain lower compared to the MICU population. Our findings support the growing complexity of care in tertiary CICUs. Further studies are required to explore the association between critical care delivery and outcomes in this evolving population. PMID- 29187012 TI - Targeted therapies in non-small cell lung cancer: a focus on ALK/ROS1 tyrosine kinase inhibitors. AB - INTRODUCTION: Anaplastic lymphoma kinase (ALK) and ROS1 rearrangements define important molecular subgroups of advanced non-small cell lung cancer (NSCLC). The identification of these genetic driver alterations created new potential for highly active therapeutic interventions. After discovery of ALK rearrangements in NSCLC, it was recognized that these confer sensitivity to ALK inhibition. Areas covered: Crizotinib, the first-in-class ALK/ROS1/MET inhibitor, was initially approved as second-line treatment of ALK-positive advanced NSCLC but after this, it was firmly established as the standard first-line therapy for advanced ALK positive NSCLC. After initial response to crizotinib, tumors inevitably relapse. Next-generation ALK inhibitors, more potent and brain-penetrable than crizotinib, may be effective in re-inducing remissions when cancers are still addicted to ALK. Ceritinib and alectinib are approved for metastatic ALK positive NSCLC patients, while brigatinib received granted accelerated approval by the United States Food and Drug Administration. Regarding ROS1 rearrangement, to date crizotinib is the only ALK-tyrosine kinase inhibitor receiving indication as treatment of ROS1 positive advanced NSCLC. Expert commentary: Although novel ALK inhibitors are under clinical investigation compared to crizotinib as front-line treatment for ALK-positive NSCLC, nowadays the current standard first-line therapy for these patients is crizotinib. Further research will clarify the best management of ALK-positive NSCLC, above all who progress on first-line crizotinib. PMID- 29187013 TI - Engineered tubular structures based on chitosan for tissue engineering applications. AB - The development of versatile tubular structures is a subject of broad interest in tissue engineering applications. Herein, we demonstrate the production of tubular structures based on chitosan through a combination of dipping, freeze-drying and supercritical technology approaches. The combination of these techniques yields versatile tubes with a perfectly defined hollow imprint, which upon chemical cross-linking with genipin acquire enhanced mechanical properties (Young Modulus ( E) and ultimate tensile stress (sigmamax)), as well as improved stability in wet conditions. The biological performance reveals that cells remain attached, well-spread and viable on the surface of cross-linked tubes. As so, is envisioned that our methodology opens up new avenues on tissue engineering approaches, where the design of tubular structures with tuned length, diameter and elasticity is required. PMID- 29187014 TI - Fenestrated TEVAR Using a Guidewire Fixator for Anchoring in Aortic Arch Target Vessels. AB - PURPOSE: To report a new facilitated method for securing target vessel access during single fenestrated and branched thoracic endovascular repair using a guidewire fixator. TECHNIQUE: The Liungman Guidewire Fixator (LGF) includes a 0.035-inch guidewire that is fitted with a stopper close to the distal end and a self-expanding anchoring element that is freely movable over the guidewire to the point of the stopper. The technique of using a LGF for anchoring in a target vessel is described in a 75-year-old woman with a 53-mm saccular arch aneurysm. She was treated with a fenestrated Zenith stent-graft that had a catheter preloaded fenestration for the left subclavian artery (LSA) and a scallop for the left common carotid artery. To avoid through-and-through wire and brachial access, the LGF was used to secure the guidewire in the LSA during stent-graft deployment. CONCLUSION: The use of an LGF for anchoring in the target LSA during fenestrated arch endografting was feasible and safe.

We present a unique case of submitral aneurysm which developed after pulmonary artery banding in a three-year-old girl with complex congenital heart disease. The aneurysmal sac was burrowing into the interatrial septum. PMID- 29187016 TI - Adolescent Female With Turner's Syndrome and 46,X,der(Y) del(Y)(p11.2)del(q11.2) Karyotype With Gonadoblastoma and Dysgerminoma. AB - Gonadal dysgenesis patients with Y chromosomal material are subject to increased risk for germ cell tumors. We report a case of an adolescent female presenting with Turner-like syndrome with primary amenorrhea and Tanner stage 1 breast development. Karyotype showed one X chromosome and a minute pericentromeric fragment of Y chromosome without any functional Y genes in all the cells, unlike a mosaic pattern, represented as 46,X,der(Y)del(Y)(p11.2)del(q11.2). Laparoscopic bilateral gonadectomy was performed due to presence of Y chromosome material and histopathology confirmed gonadoblastoma with a focus of dysgerminoma of the right ovary. A robotic-assisted surgical staging for dysgerminoma was performed which was confirmed to be negative for malignancy. This points at the putative genes for gonadoblastoma to be present around the centromere of the Y chromosome. PMID- 29187017 TI - Anti-apoptotic effect of 3-aminobenzamide, an inhibitor of poly (ADP-ribose) polymerase, against multiple organ damage induced by gamma irradiation in rats. AB - PURPOSE: This study aimed to investigate the effect of 3-aminobenzamide (3-AB) in doses of 5, 10 and 15 mg/kg on the inhibition of Poly (ADP-ribose) polymerase (PARP) when combined with ionizing radiation (IR). MATERIAL AND METHODS: Rats were treated intraperitonealy, one hour prior to irradiation at a dose level of 6 Gray (Gy) and were sacrificed 24 hours after irradiation. Control groups were run concurrently. RESULTS: IR led to an increase of thiobarbituric acid reactive substance (TBARS), nitrite as well as a decrease in total antioxidant capacity associated increase in myeloperoxidase (MPO) with the expression of cyclooxygenase-2 (COX-2). Moreover, IR caused an increase in serum lactate dehydrogenase (LDH) activity and cytosolyic Ca+2 associated with an expression of Caspase-3 as well as a decline in complex-I activity and adenosine triphosphate (ATP) level. Pretreatment with 5 and 10 mg/kg of 3AB guarded against the changes in all the measured parameters, conversely the dose of 15 mg/kg showed no effect on the damage induced by irradiation in the selected tissues. Moreover, 3AB has a dose-dependent effect on viability of Vero cells. CONCLUSION: The selected low doses of 3AB rather than the higher dose (15 mg/kg) protected against radiation induced multiple organ damage. PMID- 29187019 TI - Microfluidic system for synthesis of nanofibrous conductive hydrogel and muscle differentiation. AB - Microscale hydrogels can be synthesized within microfluidic systems and subsequently assembled to make tissues composed of units such as myofibers in muscle tissue. Importantly, the nanofibrous surface of hydrogels is essential for tissue engineering aims due to inducing beneficial cell-surface interactions. In this study, a new microfluidic platform, embedded with a hydrogel, was introduced that allowed for performing multiple non-parallel steps for the synthetic approaches. Satellite cells, isolated from skeletal tissues of 10-day Naval Medical Research Institute-murine were cultured on the prepared hydrogel within the microfluidic system. The normal proliferation of satellite cells occurred after the employment of continuous perfusion cell culture. Interestingly, the positive results of the immuno-staining assay along with the cellular bridge formation between hydrogel fragments confirmed the muscle differentiation of seeded satellite cells. Further on, COMSOl simulations anticipated that the thermodynamic conditions of the microfluidic system during hydrogel synthesis had to be kept steady while a shear stress value of 15 * 10-6 Pa was calculated, exhibiting a cell culture condition free of environmental stress. PMID- 29187020 TI - A Rare Case of Pediatric Chronic Myelogenous Leukemia Presenting With Severe Thrombocytosis Without Leukocytosis. AB - Pediatric chronic myelogenous leukemia is uncommon. We report a pediatric patient with chronic myelogenous leukemia presenting with a normal white blood cell count and no circulating immature myeloid cells. The patient presented with extreme thrombocytosis (platelet count range: 2175-3064 * 109/L) noted incidentally. No splenomegaly was found. Examination of the bone marrow aspirate revealed normal cellularity and normal myeloid: erythroid ratio with marked megakaryocytic hyperplasia. Molecular studies on the bone marrow aspirate detected both the major BCR/ABL1 p210 fusion transcript (9280 copies; p210/ ABL1 ratio: 38.2%) and the minor p190 transcript (below limit of quantitation). The platelet count normalized within 2 weeks after treatment with the second-generation tyrosine kinase inhibitor dasatinib. Follow-up after 3 months revealed a 1.87 log reduction in p210 transcripts compared to diagnosis and no detectable p190 transcripts. This case highlights the need to include BCR/ABL1 fusion testing to accurately diagnose pediatric patients presenting with isolated thrombocytosis.

PMID- 29187018 TI - Targeting methionine with oral recombinant methioninase (o-rMETase) arrests a patient-derived orthotopic xenograft (PDOX) model of BRAF-V600E mutant melanoma: implications for chronic clinical cancer therapy and prevention. AB - The elevated methionine (MET) use by cancer cells is termed MET dependence and may be the only known general metabolic defect in cancer. Targeting MET by recombinant methioninase (rMETase) can arrest the growth of cancer cells in vitro and in vivo. We previously reported that rMETase, administrated by intra peritoneal injection (ip-rMETase), could inhibit tumor growth in a patient derived orthotopic xenograft (PDOX) model of a BRAF-V600E mutant melanoma. In the present study, we compared ip-rMETase and oral rMETase (o-rMETase) for efficacy on the melanoma PDOX. Melanoma PDOX nude mice were randomized into four groups of 5 mice each: untreated control; ip-rMETase (100 units, i.p., 14 consecutive days); o-rMETase (100 units, p.o., 14 consecutive days); o-rMETase+ip-rMETase (100 units, p.o.+100 units, i.p., 14 consecutive days). All treatments inhibited tumor growth on day 14 after treatment initiation, compared to untreated control (ip-rMETase, p<0.0001; o-rMETase, p<0.0001; o-rMETase+ip-rMETase, p<0.0001). o rMETase was significantly more effective than ip-rMETase (p = 0.0086). o rMETase+ip-rMETase was significantly more effective than either mono-therapy: ip rMETase, p = 0.0005; or o-rMETase, p = 0.0367. The present study is the first demonstrating that o-rMETase is effective as an anticancer agent. The results of the present study indicate the potential of clinical development of o-rMETase as an agent for chronic cancer therapy and for cancer prevention and possibly for life extension since dietary MET reduction extends life span in many animal models.

AB - We report an unusual presentation of a large left atrial myxoma in an eight-year old girl who presented with the sudden onset of chorea. This case illustrates the fact that the presentation of chorea in nonendemic areas for rheumatic fever should raise suspicion for a myxoma. The chorea resolved soon after removal of the myxoma, supporting the hypothesis of an immune-mediated mechanism, or manifestation of paraneoplastic syndrome secondary to the myxoma. PMID- 29187023 TI - Biopsy-proven Hepatocellular Carcinoma in a 53-year-old Woman With Arginase Deficiency. AB - Arginase 1 deficiency, the least common urea cycle disorder, commonly presents with childhood-onset spastic paraplegia, progressive neurologic impairment, epilepsy, and developmental delay or regression. Biopsy-proven cirrhosis and hepatocellular carcinoma diagnosed via clinical and imaging studies (but without biopsy confirmation) have been previously reported. We report, herein, a case of a 53-year-old woman with arginase 1 deficiency who developed symptoms of "abdominal bloating." Imaging studies (ultrasound and magnetic resonance imaging) demonstrated 2 dominant hepatic masses, measuring 5.9 cm and 5.7 cm in greatest dimensions and located in hepatic segments 5 and 6, respectively. Core biopsies of the lesions demonstrated well-differentiated hepatocellular carcinoma. Immunohistochemistry performed on the segment 5 lesion was negative for arginase 1. This report represents, to the best of our knowledge, the first case of biopsy proven hepatocellular carcinoma in an individual with arginase 1 deficiency. PMID- 29187024 TI - Ossifying Renal Tumor of Infancy: Report of a Case With Positive WT1 Immunohistochemistry and High Mitotic Index and Review of the Literature. AB - Ossifying renal tumor of infancy (ORTI) is a rare, benign pediatric tumor of the kidney. Since first reported by Chatten in 1980, 23 cases have been published. Previous authors have argued that ORTI might originate from nephrogenic rests, thereby sharing a pathogenic relationship with Wilms' tumor (WT). ORTI is characterized histologically by a population of polygonal osteoblast-like cells around an osteoid core and densely cellular component of blastemal-like or spindle cells. While the immunohistochemical profile of the cellular components has been reported, to the best of our knowledge, the status of WT1 expression has only been reported once, where it showed negative marking. Mitoses have been described only sporadically in this neoplasm. We report on a case of ORTI with positive WT1 immunohistochemical marking and numerous mitoses. This case highlights a possible pitfall for misdiagnosing ORTI as a WT and provides additional insight into its pathogenesis. PMID- 29187025 TI - Positive Aspects of Caregiving and Caregiver Burden: A Study of Caregivers of Patients With Dementia. AB - BACKGROUND: Now positive aspect of caregiving (PAC) is well-defined as caregiver gains, satisfaction, meaningful life, and enhanced family relationship. The adjusted association of PAC and caregiver burden is not well acknowledged. This study investigated the association of caregiver burden and PAC adjusting for potential confounders. METHODS: This was a cross-sectional study that recruited 132 caregivers. A linear regression model with PAC was used to estimate the adjusted associations. RESULTS: The caregiver burden was negatively associated with PAC (mean difference in PAC per a 1-unit increase in caregiver burden = 0.12, 95% confidence interval: -0.18 to -0.056; P < .001). This association remained after adjustment for caregivers' age and marital status as well as patients' dependency level. CONCLUSION: The negative significant association of caregiver burden with PAC reinforces the need for interventional and/or educational programs aiming at decreasing the overall imposed burden. This can play an important role in improving caregivers' general health and quality of life. PMID- 29187026 TI - The Relationship Between Social Cognition and Awareness in Alzheimer Disease. AB - A large body of evidence highlights the social cognitive impairment in neurodegenerative diseases such Alzheimer disease (AD). This study investigated the relationship among social and emotional functioning (SEF), awareness of disease, and other clinical aspects in people with AD (PwAD). A consecutive series of 50 people with mild to moderate AD and their 50 family caregivers were assessed. There was a significant difference between self-rated SEF and informant rated SEF. In 56% of PwAD, self-rated SEF is lower than informant-rated SEF. People with AD mostly presented with mildly impaired awareness of the disease (56%), 20% had moderately impaired awareness of the disease, and 6% were unaware of the disease. The multivariate linear regression showed that informant-rated SEF was related to the social functioning, and relationships, domains of awareness of disease, and the PwAD informant-rated quality of life. The relationship between SEF and awareness of social functioning and relationship domain shows that they are comprised of judgments related to perceptions about oneself, values, and beliefs qualitatively different from awareness of memory or functionality, which can be directly observed. PMID- 29187027 TI - Actual versus recommended storage temperatures of oral anticancer medicines at patients' homes. AB - Background Substantial quantities of unused medicines are returned by patients to the pharmacy each year. Redispensing these medicines would reduce medicinal waste and health care costs. However, it is not known if medicines are stored by patients as recommended in the product label. Inadequate storage may negatively affect the medicine and reduce clinical efficacy whilst increasing the risk for side effects. Objective To investigate the proportion of patients storing oral anticancer medicines according to the temperature instructions in the product label. Methods Consenting adult patients from six Dutch outpatient hospital pharmacies were included in this study if they used an oral anticancer medicine during February 2014 - January 2015. Home storage temperatures were assessed by inclusion of a temperature logger in the original cancer medicines packaging. The primary outcome was the proportion of patients storing oral anticancer medicines as specified in the Summary of Product Characteristics, either by recalculating the observed temperature fluctuations to a single mean kinetic temperature or by following the temperature instructions taking into account a consecutive 24-h tolerance period. Results Ninety (81.1%) of the 111 included patients (47.8% female, mean age 65.2 (SD: 11.1)) returned their temperature loggers to the pharmacy. None of the patients stored oral anticancer medicines at a mean kinetic temperature above 25C, one patient stored a medicine requiring storage below 25C longer than 24 h above 25C. None of the patients using medicines requiring storage below 30C kept their medicine above 30C for a consecutive period of 24 h or longer. Conclusion The majority of patients using oral anticancer medicines store their medicines according to the temperature requirements on the product label claim. Based on our results, most oral anticancer medicines will not be negatively affected by temperature conditions at patients' homes for a maximum of three months and are likely to be suitable for redispensing. PMID- 29187028 TI - Rat Model of Brain Injury to Occupants of Vehicles Targeted by Land Mines: Mitigation by Elastomeric Frame Designs. AB - Many victims of blast traumatic brain injury (TBI) are occupants of vehicles targeted by land mines. A rat model of under-vehicle blast TBI was used to test the hypothesis that the ensuing neuropathology and altered behavior are mitigated by vehicle frame designs that dramatically reduce blast-induced acceleration (G force). Male rats were restrained on an aluminum platform that was accelerated vertically at up to 2850g, in response to detonation of an explosive positioned under a second platform in contact with the top via different structures. The presence of elastomeric, polyurea-coated aluminum cylinders between the platforms reduced acceleration by 80% to 550g compared with 2350g with uncoated cylinders. Moreover, 67% of rats exposed to 2850g, and 20% of those exposed to 2350g died immediately after blast, whereas all rats subjected to 550g blast survived. Assays for working memory (Y maze) and anxiety (Plus maze) were conducted for up to 28 days. Rats were euthanized at 24 h or 29 days, and their brains were used for histopathology and neurochemical measurements. Rats exposed to 2350g blasts exhibited increased cleaved caspase-3 immunoreactive neurons in the hippocampus. There was also increased vascular immunoglobulin (Ig)G effusion and F4/80 immunopositive macrophages/microglia. Blast exposure reduced hippocampal levels of synaptic proteins Bassoon and Homer-1, which were associated with impaired performance in the Y maze and the Plus maze tests. These changes observed after 2350g blasts were reduced or eliminated with the use of polyurea-coated cylinders. Such advances in vehicle designs should aid in the development of the next generation of blast-resistant vehicles. PMID- 29187029 TI - Comparison of different approaches for identifying subnetworks in metabolic networks. AB - A metabolic network model provides a computational framework for studying the metabolism of a cell at the system level. The organization of metabolic networks has been investigated in different studies. One of the organization aspects considered in these studies is the decomposition of a metabolic network. The decompositions produced by different methods are very different and there is no comprehensive evaluation framework to compare the results with each other. In this study, these methods are reviewed and compared in the first place. Then they are applied to six different metabolic network models and the results are evaluated and compared based on two existing and two newly proposed criteria. Results show that no single method can beat others in all criteria but it seems that the methods introduced by Guimera and Amaral and Verwoerd do better on among metabolite-based methods and the method introduced by Sridharan et al. does better among reaction-based ones. Also, the methods are applied to several artificial networks, each constructed from merging a few KEGG pathways. Then, their capability to recover those pathways are compared. Results show that among metabolite-based methods, the method of Guimera and Amaral does better again, however, no notable difference between the performances of reaction-based methods was detected.

AB - Hemophagocytic Lymphohistiocytosis (HLH) is a hyperinflammatory disorder that may be encountered as a primary or secondary phenomenon. HLH secondary to lymphoma has been described, more frequently in adults than in children. T-cell/Histiocyte rich B-cell lymphoma (THRLBCL) is a large B-cell lymphoma that resides in a microenvironment of robust host immune response and has previously been associated with HLH in adults. Here, we describe the first case of HLH secondary to THRLBCL in an adolescent patient. PMID- 29187031 TI - Minocycline plus N-Acetylcysteine Reduce Behavioral Deficits and Improve Histology with a Clinically Useful Time Window. AB - There are no drugs to manage traumatic brain injury (TBI) presently. A major problem in developing therapeutics is that drugs to manage TBI lack sufficient potency when dosed within a clinically relevant time window. Previous studies have shown that minocycline (MINO, 45 mg/kg) plus N-acetylcysteine (NAC, 150 mg/kg) synergistically improved cognition and memory, modulated inflammation, and prevented loss of oligodendrocytes that remyelinated damaged white matter when first dosed 1 h after controlled cortical impact (CCI) in rats. We show that MINO (45 mg/kg) plus NAC (150 mg/kg) also prevent brain injury in a mouse closed head injury (CHI) TBI model. Using the CHI model, the concentrations of MINO and NAC were titrated to determine that MINO (22.5 mg/kg) plus NAC (75 mg/kg) was more potent than the original formulation. MINO (22.5 mg/kg) plus NAC (75 mg/kg) also limited injury in the rat CCI model. The therapeutic time window of MINO plus NAC was then tested in the CHI and CCI models. Mice and rats could acquire an active place avoidance task when MINO plus NAC was first dosed at 12 h post-injury. A first dose at 12 h also limited gray matter injury in the hippocampus and preserved myelin in multiple white matter tracts. Mice and rats acquired Barnes maze when MINO plus NAC was first dosed at 24 h post-injury. These data suggest that MINO (22.5 mg/kg) plus NAC (75 mg/kg) remain potent when dosed at clinically useful time windows. Both MINO and NAC are drugs approved by the Food and Drug Administration and have been administered safely to patients in clinical trials at the doses in the new formulation. This suggests that the drug combination of MINO plus NAC may be effective in treating patients with TBI.

AB - Objective Herein, we report a case of a deceased newborn with prenatally detected hydrocephalus. Postnatal findings included abnormal brain imaging and electroencephalogram, optic nerve abnormalities, and elevated creatine kinase (CK). No underlying genetic etiology had been previously identified for the proband, despite testing with a congenital muscular dystrophy gene panel. Methods Diagnostic exome sequencing (DES) was performed on the proband-parents trio, and candidate alterations were confirmed using automated fluorescence dideoxy sequencing. Results Exome sequencing of the proband, mother and father identified a previously unreported apparently de novo heterozygous tubulin, beta-3 ( TUBB3) c.523G>C (p.V175L) alteration in the proband. Conclusion Overall, DES established a likely molecular genetic diagnosis for a postmortem case after traditional testing methods were uninformative. The DES results allowed for reproductive options, such as preimplantation genetic diagnosis and/or prenatal diagnosis, to be available to the parents in future pregnancies. PMID- 29187033 TI - Second re-irradiation: a narrative review of the available clinical data. AB - BACKGROUND: Considerable controversy exists about the safety and efficacy of second re-irradiations (three courses of radiotherapy to overlapping volumes). Therefore, all published clinical studies were reviewed. MATERIAL AND METHODS: Contemporary and historical articles were identified. Outcomes such as survival, local control, symptom improvement and side effects were extracted. Contemporary results were grouped by anatomical location of the re-irradiated region in the body. RESULTS: Most data were derived from central nervous system tumors, pelvic tumors and bone metastases. We could include nine contemporary, retrospective studies with 2-25 patients each. Nearly, all patients were treated with palliative intent. Most of the prescribed re-irradiation regimens were highly individualized and thus difficult to compare. Symptomatic responses were recorded in most patients. In palliatively treated patients with pelvic and bony target volumes, high-grade toxicity was uncommon. CONCLUSIONS: Despite of issues related to study size, length of follow-up and calculation of lifetime cumulative equivalent dose, the available data provide an initial framework for future studies and discussion of dose constraints. Selected dose-fractionation regimens may result in a satisfactory therapeutic ratio even after two previous courses of radiotherapy, if these were well tolerated.

PMID- 29187035 TI - Immobilisation of hydroxyapatite-collagen on polydopamine grafted stainless steel 316L: Coating adhesion and in vitro cells evaluation. AB - The utilisation of hydroxyapatite and collagen as bioactive coating materials could enhance cells attachment, proliferation and osseointegration. However, most methods to form crystal hydroxyapatite coating do not allow the incorporation of polymer/organic compound due to production phase of high sintering temperature. In this study, a polydopamine film was used as an intermediate layer to immobilise hydroxyapatite-collagen without the introduction of high sintering temperature. The surface roughness, coating adhesion, bioactivity and osteoblast attachment on the hydroxyapatite-collagen coating were assessed as these properties remains unknown on the polydopamine grafted film. The coating was developed by grafting stainless steel 316L disks with a polydopamine film. Collagen type I fibres were then immobilised on the grafted film, followed by the biomineralisation of hydroxyapatite. The surface roughness and coating adhesion analyses were later performed by using AFM instrument. An Alamar Blue assay was used to determine the cytotoxicity of the coating, while an alkaline phosphatase activity test was conducted to evaluate the osteogenic differentiation of human fetal osteoblasts on the coating. Finally, the morphology of cells attachment on the coating was visualised under FESEM. The highest RMS roughness and coating adhesion were observed on the hydroxyapatite-collagen coating (hydroxyapatite coll-dopa). The hydroxyapatite-coll-dopa coating was non-toxic to the osteoblast cells with greater cells proliferation, greater level of alkaline phosphate production and more cells attachment. These results indicate that the immobilisation of hydroxyapatite and collagen using an intermediate polydopamine is identical to enhance coating adhesion, osteoblast cells attachment, proliferation and differentiation, and thus could be implemented as a coating material on orthopaedic and dental implants.

AB - Common causes of fetal anemia and hydrops include parvovirus B19 infection during the first 2 trimesters of pregnancy, as well as maternal alloimmunization to RhD with subsequent hemolytic disease of the fetus and newborn (HDFN) in an RhD positive fetus. Although both of these conditions have historically caused significant fetal morbidity and mortality, the advent of intrauterine transfusion (IUT) over the last few decades has dramatically improved outcomes. Prior literature has extensively documented placental changes associated with untreated parvovirus infection and RhD HDFN in intrauterine fetal demises and preterm births; however, histopathologic changes in term placentas from term infants treated with IUT have not been reported. We present placental findings in 2 cases of parvovirus B19-associated hydrops and 2 cases of RhD HDFN-associated hydrops in term infants after IUT, highlighting unique aspects that may be diagnostically useful for the examining pathologist. PMID- 29187037 TI - Modeling a Predictive Energy Equation Specific for Maintenance Hemodialysis. AB - BACKGROUND: Hypermetabolism is theorized in patients diagnosed with chronic kidney disease who are receiving maintenance hemodialysis (MHD). We aimed to distinguish key disease-specific determinants of resting energy expenditure to create a predictive energy equation that more precisely establishes energy needs with the intent of preventing protein-energy wasting. MATERIALS AND METHODS: For this 3-year multisite cross-sectional study (N = 116), eligible participants were diagnosed with chronic kidney disease and were receiving MHD for at least 3 months. Predictors for the model included weight, sex, age, C-reactive protein (CRP), glycosylated hemoglobin, and serum creatinine. The outcome variable was measured resting energy expenditure (mREE). Regression modeling was used to generate predictive formulas and Bland-Altman analyses to evaluate accuracy. RESULTS: The majority were male (60.3%), black (81.0%), and non-Hispanic (76.7%), and 23% were >=65 years old. After screening for multicollinearity, the best predictive model of mREE ( R2 = 0.67) included weight, age, sex, and CRP. Two alternative models with acceptable predictability ( R2 = 0.66) were derived with glycosylated hemoglobin or serum creatinine. Based on Bland-Altman analyses, the maintenance hemodialysis equation that included CRP had the best precision, with the highest proportion of participants' predicted energy expenditure classified as accurate (61.2%) and with the lowest number of individuals with underestimation or overestimation. CONCLUSIONS: This study confirms disease specific factors as key determinants of mREE in patients on MHD and provides a preliminary predictive energy equation. Further prospective research is necessary to test the reliability and validity of this equation across diverse populations of patients who are receiving MHD. PMID- 29187038 TI - Does Having a Relative in Dialysis Therapy Affect Attitudes Toward Kidney Donating? AB - CONTEXT: The majority of kidney transplants in Turkey are performed from live donors and from those among first-degree relatives. OBJECTIVE: To compare the view points and the attitudes of individuals who have relatives undergoing dialysis toward kidney donation treatment with those who do not. DESIGN: The study was designed as a descriptive study, which used simple random sampling. SETTING: The sample consisted of 204 individuals, divided into 2 groups: those whose relatives underwent dialysis treatment (group A, n = 106) and those whose relatives did not (group B, n = 98). RESULTS: The means of the total points obtained in "Kidney Donation Attitude Inventory" (KDAI) by individuals in group A were statistically significantly higher than those obtained by individuals in group B ( P = .001). Although there was a statistically significant difference in the educational status, status of willing to donate their kidneys and being a relative of an individual awaiting a kidney transplant, and the mean total points obtained from the KDAI between the groups ( P < .05), no statistically significant difference was determined between the means of the obtained total points and the gender and the duration of dialysis treatment ( P > .05). CONCLUSION: The attitudes of the relatives of individuals undergoing dialysis treatment toward kidney donation were determined to be more positive.

PMID- 29187040 TI - Parenteral Soybean Oil Induces Hepatosteatosis Despite Addition of Fish Oil in a Mouse Model of Intestinal Failure-Associated Liver Disease. AB - BACKGROUND: Replacement of parenteral soybean oil (SO) with fish oil (FO) is an effective therapy for intestinal failure-associated liver disease (IFALD) in children. However, practitioners remain concerned about the risk of essential fatty acid deficiency (EFAD) and sometimes treat IFALD with a combination of 50% SO and 50% FO emulsions. The purpose of this study was to determine if mixing 50% SO and 50% FO emulsions would prevent hepatosteatosis in a murine model of parenteral nutrition (PN)-induced hepatosteatosis. METHODS: C57BL/6 mice were randomized to receive oral PN with parenteral saline, FO, SO, or a mixture of 50% FO and 50% SO for 19 days. Fatty acid analysis, histologic evaluation, Nonalcoholic Steatohepatitis Clinical Research Network (NSCRN) scores, and reverse-transcriptase polymerase chain reaction for key lipogenic genes were performed. RESULTS: The PN + saline group was the only group with EFAD, with a serum and hepatic triene/tetraene ratio of 0.53. NSCRN scores were highest in the PN + SO group (5.5; 95% confidence interval [CI], 4.9-6.1), followed by the PN + FO/SO (4.5; 95% CI, 3.5-5.5) group, with the lowest score in the PN + FO (2.0; 95% CI, 1.1-2.9) group. Acetyl CoA carboxylase alpha and acetyl CoA carboxylase beta expression was lower in the PN + FO group than in the PN + FO/SO or PN + SO groups. CONCLUSIONS: Our data demonstrate that a mixed fat emulsion of 50% SO and 50% FO is inferior to 100% FO in reducing hepatosteatosis in this model. These data suggest that use of parenteral SO with parenteral FO, in a 1:1 ratio, may still contribute to liver injury, although it is less hepatotoxic than pure SO. PMID- 29187042 TI - Effect of Discontinuation of Manganese Supplementation From Home Parenteral Nutrition Solutions on Whole-Blood Levels and Magnetic Resonance Imaging of the Brain: A 5-Year Cohort Study. AB - BACKGROUND: Manganese (Mn) is included in current premixed multiple trace element (TE) additives for home parenteral nutrition (HPN). However, there is a risk of oversupplementation of Mn due to contamination from PN additives. Oversupplementation can produce Mn toxicity with neurologic symptoms and abnormalities on brain magnetic resonance imaging (MRI). In 2009, we reported that whole-blood Mn levels were above the upper limit of normal in 16 HPN patients, with 81% having MRI findings. Subsequently, we removed Mn supplementation from all our HPN patients. We present a 5-year follow-up here. METHODS: This is a prospective cohort study on 11 of the surviving 16 patients on HPN. All patients had Mn removed from PN and had yearly monitoring of blood Mn levels. Eight patients had a repeat MRI to evaluate for resolution of basal ganglia deposits. Patient demography, clinical history, and bloodwork were recorded. RESULTS: Five of 6 patients who initially had elevated Mn levels had normal levels on follow-up. All patients who had Mn levels measured serially had a decrease in levels; the mean percent decrease of Mn was 38.1% (range, 10.1% 53.8%). Two patients had elevated Mn despite the absence of supplementation. Six of 8 patients who had repeat MRIs had complete resolution abnormalities. CONCLUSIONS: Removal of Mn as an additive in HPN solutions resulted in resolution of MRI abnormalities in most patients. Over 5 years, all patients except for 1 maintained normal blood Mn levels. Therefore, Mn levels should be monitored and supplementation be individualized. PMID- 29187041 TI - Restrictive Cardiomyopathy or Constrictive Pericarditis: An Unresolved Conundrum. AB - Cardiomyopathy may have a variety of causes and may lead to significant morbidity. Often, there is no "perfect" treatment. New investigative techniques may add insight but retain the possibility of uncertainty. The distinction between restrictive cardiomyopathy and pericardial constriction may be challenging, particularly when considering the incidence of these entities. This distinction may significantly impact patient management and this is becoming increasingly important in the context of donor organ austerity. We present a case of a 17-year-old male to illustrate the overlap highlighting this debate and our subsequent management. PMID- 29187043 TI - An Atypical Presentation of Alagille Syndrome. AB - Alagille syndrome is a multisystem disorder classically involving the liver, heart, vertebrae, facial features, and the eyes. In this case report, we document a case of Alagille syndrome with an atypical clinical and histopathologic presentation and subsequent identification of a novel JAG1 missense mutation. This case highlights that there may be both atypical clinical and pathologic findings in mutation-proven Alagille syndrome and that the diagnosis of Alagille syndrome should be considered in cases of ongoing bile duct damage in the setting of early-onset jaundice, cholestasis, hepatosplenomegaly, posterior embryotoxon in the eyes, and butterfly vertebrae. PMID- 29187044 TI - Smooth time-dependent receiver operating characteristic curve estimators. AB - The receiver operating characteristic curve is a popular graphical method often used to study the diagnostic capacity of continuous (bio)markers. When the considered outcome is a time-dependent variable, two main extensions have been proposed: the cumulative/dynamic receiver operating characteristic curve and the incident/dynamic receiver operating characteristic curve. In both cases, the main problem for developing appropriate estimators is the estimation of the joint distribution of the variables time-to-event and marker. As usual, different approximations lead to different estimators. In this article, the authors explore the use of a bivariate kernel density estimator which accounts for censored observations in the sample and produces smooth estimators of the time-dependent receiver operating characteristic curves. The performance of the resulting cumulative/dynamic and incident/dynamic receiver operating characteristic curves is studied by means of Monte Carlo simulations. Additionally, the influence of the choice of the required smoothing parameters is explored. Finally, two real applications are considered. An R package is also provided as a complement to this article. PMID- 29187045 TI - Terminal Deoxynucleotidyl Transferase (TdT)-negative Lymphoblastic Leukemia in Pediatric Patients: Incidence and Clinical Significance. AB - Pediatric terminal deoxynucleotidyl tranferase (TdT)-negative precursor B- or T lymphoblastic leukemia/lymphoma (B-LL and T-LL) cases are rare and their prognostic significance remains controversial. We aimed to determine the frequency of TdT-negative B- and T-LL in the community hospital setting. Between 2005 and 2015, 43 pediatric patients were diagnosed with lymphoblastic leukemia at our institution, of which 6 (14%) were characterized as TdT-negative by flow cytometric analysis. Four of these 6 patients had B-LL and the other 2 had T-LL. Two of the 6 TdT-negative patients also had undetectable CD34 expression by flow cytometry (TdT/CD34 double-negatives). Subsequent paraffin immunohistochemistry confirmed the negative CD34 expression in both cases. By contrast, all the 6 patients had weak TdT-like immunoreactivity in their marrow despite the negative flow cytometric analysis. Furthermore, neither TdT/CD34-negative cases showed myc rearrangement by fluorescent in situ hybridization, ruling out Burkitt leukemia as a differential diagnostic consideration. We conclude that TdT-negative pediatric B- and T-LL cases (especially those that are TdT/CD34 double-negative) may pose diagnostic challenge to hematopathologists, and ancillary studies (paraffin immunohistochemistry to detect TdT and fluorescent in situ hybridization to exclude myc rearrangement) may be instrumental in reaching the correct diagnosis. PMID- 29187046 TI - Denosumab Improves Bone Mineral Density in Patients With Intestinal Failure Receiving Home Parenteral Nutrition: Results From a Randomized, Controlled Clinical Trial. AB - AIM: Low bone mineral density (BMD) is commonly reported in patients receiving home parenteral nutrition (HPN). Oral and intravenous calcium, vitamin D, and bisphosphonates have been used to treat BMD but with low efficiency due to their limited absorption and patient compliance. Denosumab is a new drug that helps prevent osteoclast development and activation and led to decreased bone resorption in some studies. The aim of this study was to assess its value in HPN patients. METHODS: Between November 2011 and March 2013, 49 patients receiving HPN (29 women, 20 men, mean age 55.3 years) who met the eligibility criteria were randomly assigned to a denosumab or control group. Regional dual-energy x-ray absorptiometry of the spine and hip was performed before therapy and after 12 months. BMD, T score, and z score were assessed. RESULTS: Fifteen patients received 2 doses of therapy and were fully reassessed after 1 year. At baseline and after 12 months, the absorptiometry revealed T scores of -3.439 standard deviations (SD) vs -2.33 SD at lumbar segment 2 (L2) and -2.957 SD vs -2.067 SD at lumbar segment 3 (L3), z scores of -2.24 SD vs -1.36 SD at L2 and -1.995 vs 1.067 SD at L3, and BMD of 0.801 vs 0.946 at L2 and 0.857 vs 0.979 at L3, respectively. Two serious outcomes were reported, without any correlation to the intervention. Two patients were weaned off HPN and hence discontinued. One patient experienced sciatica, resulting in discontinuation of the intervention. CONCLUSIONS: This study showed that denosumab may be a valuable treatment option for improving BMD in HPN patients. PMID- 29187047 TI - Defining and Using Preoperative Predictors of Diabetic Remission Following Bariatric Surgery. AB - BACKGROUND: Diabetes remission is defined as the return of glycemic control in the absence of medication or insulin use after bariatric surgery. We sought to identify and assess the clinical utility of a predictive model for remission of type 2 diabetes mellitus in a population seeking bariatric surgery. METHOD: A retrospective cohort design was applied to presurgical data on patients referred for Roux-en-Y gastric bypass (RYGB) or vertical sleeve gastrectomy (VSG). The model developed from logistic regression was compared with a published model through receiver operating characteristic analyses. RESULTS: At 12 months postoperatively, 59.7% of the cohort was remitted, with no differences between RYGB and VSG. Logistic regression analyses yielded a model in which 4 preoperative variables reliably predicted remission. A Hosmer-Lemeshow goodness of-fit test result of 0.204 indicated good fit of the developed prediction model to our outcome data. The predictive accuracy of this prediction model was compared with a published model, and an associated variation with diabetes years was substituted for age in our patient population. Our model was the most accurate. CONCLUSIONS: Using these predictors, healthcare providers may be able to better counsel patients who are living with diabetes and considering bariatric surgery on the likelihood of achieving remission from the intervention. This refined prediction model requires further testing in a larger sample to evaluate its external validity. PMID- 29187048 TI - Multitargeted Feeding Strategies Improve Nutrition Outcome and Are Associated With Reduced Pneumonia in a Level 1 Trauma Intensive Care Unit. AB - BACKGROUND: Factors impeding delivery of adequate enteral nutrition (EN) to trauma patients include delayed EN initiation, frequent surgeries and procedures, and postoperative ileus. We employed 3 feeding strategies to optimize EN delivery: (1) early EN initiation, (2) preoperative no nil per os feeding protocol, and (3) a catch-up feeding protocol. This study compared nutrition adequacy and clinical outcomes before and after implementation of these feeding strategies. METHODS: All trauma patients aged >=18 years requiring mechanical ventilation for >=7 days and receiving EN were included. Patients who sustained nonsurvivable injuries, received parenteral nutrition, or were readmitted to the intensive care unit (ICU) were excluded. EN data were collected until patients received an oral diet or were discharged from the ICU. The improvement was quantified by comparing nutrition adequacy and outcomes between April 2014-May 2015 (intervention) and May 2012-June 2013 (baseline). RESULTS: The intervention group (n = 118) received significantly more calories (94% vs 75%, P < .001) and protein (104% vs 74%, P < .001) than the baseline group (n = 121). The percentage of patients receiving EN within 24 and 48 hours of ICU admission increased from 41% to 70% and from 79% to 96% respectively after intervention ( P < .001). Although there were fewer 28-day ventilator-free days in the intervention group than in the baseline group (12 vs 16 days, P = .03), receipt of the intervention was associated with a significant reduction in pneumonia (odds ratio, 0.53; 95% confidence interval, 0.31-0.89; P = .017) after adjusting sex and Injury Severity Score. CONCLUSIONS: Implementation of multitargeted feeding strategies resulted in a significant increase in nutrition adequacy and a significant reduction in pneumonia. PMID- 29187050 TI - Influence of Dietitians in Preventing Parenteral Nutrition Prescription Errors in Children. AB - BACKGROUND: The purpose of this study is to determine whether direct involvement by dietitians in parenteral nutrition (PN) ordering resulted in a reduction in PN prescriptions errors. METHODS: A prospective audit of PN prescriptions was undertaken at a pediatric hospital over 50 weeks. Prescriptions for PN that had dietitian involvement (dietitian group) were compared with prescriptions in which dietitians were not directly involved (nondietitian group). The number of total prescriptions, the number of prescriptions with errors, and the types of errors from both groups were recorded. Errors were classified into "dietitian preventable errors" and "nondietitian-preventable errors." Comparisons were made between prescriptions with and without errors, between dietitian-preventable and nondietitian-preventable errors, and between the dietitian and nondietitian groups per error type. RESULTS: The total number of PN prescriptions was 725 (from 45 patients) and 471 (from 66 patients) for the dietitian and nondietitian groups, respectively. The nondietitian group was more likely than the dietitian group to prescribe PN incorrectly-18.0% (85 of 471) versus 12.4% (90 of 725; P = .007)-with the nondietitian group having 1.5-times more PN prescriptions with errors (risk ratio = 1.5, 95% CI: 1.1-1.9). The total number of prescription errors was 126 and 146 for the dietitian and nondietitian groups, respectively. The dietitian group was less likely than the nondietitian group to be associated with dietitian-preventable errors: 65.9% (83 of 126) versus 87.0% (127 of 146; risk ratio = 1.3, 95% CI: 1.1-1.5; P < .0001). CONCLUSION: Dietitian input into prescription of PN reduced the number of prescriptions with errors. PMID- 29187051 TI - The New European Society for Clinical Nutrition and Metabolism Definition of Malnutrition: Application for Nutrition Assessment and Prediction of Morbimortality in an Emergency Service. AB - BACKGROUND: Recently, the European Society for Clinical Nutrition and Metabolism (ESPEN) provided novel consensus criteria for malnutrition diagnosis. This study aimed to evaluate the applicability of this instrument in combination with different nutrition screening tools (1) to identify malnutrition and (2) to predict morbidity and mortality in hospitalized patients. MATERIALS AND METHODS: Observational prospective study in 750 adults admitted to the emergency service of a tertiary public hospital. Subjective Global Assessment (SGA-reference method) and the new ESPEN criteria were used to assess nutrition status of patients, who were initially screened for nutrition risk using 4 different tools. Outcome measures included length of hospital stay, occurrence of infection, and incidence of death during hospitalization, analyzed by logistic regression. RESULTS: There was a lack of agreement between the SGA and ESPEN definition of malnutrition, regardless of the nutrition screening tool applied previously (kappa = -0.050 to 0.09). However, when Malnutrition Screening Tool and Nutritional Risk Screening-2002 (NRS-2002) were used as the screening tool, malnourished patients according to ESPEN criteria showed higher probability of infection (relative risk [RR], 1.54; 95% confidence interval [CI], 1.02-2.31 and RR, 2.06; 95% CI, 1.37-3.10, respectively), and when the NRS-2002 was used, the risk for death was 2.7 times higher (hazard ratio, 2.69; 95% CI, 1.07-6.81) in malnourished patients than in well-nourished patients. CONCLUSION: Although the new ESPEN criteria had a poor diagnostic value, it seems to be a prognostic tool among hospitalized patients, especially when used in combination with the NRS 2002. PMID- 29187053 TI - Applying a health literacy lens to youth sport: a focus on doping prevention in Germany. AB - There are two camps when it comes to youth in high-performance sports and whether competition is good or destructive. Despite opportunities for positive development, the demands of increasing competitive levels and related situational stressors among young athletes can be a double-edged sword. Doping is becoming increasingly popular and more readily available to the youth sports population. Improving the health of youth in competitive sport requires us to think about health and its determinants in a more sophisticated manner. We share a current initiative in Germany that reflects this broader thinking by integrating 'education for health literacy' as one strategy in youth sport settings with regard to doping prevention. Implications and emerging opportunities to take further action for doping prevention and health improvement applicable for German and global contexts are offered. PMID- 29187052 TI - Mesenchymal Stem Cell Therapy Prevents Abortion in CBA/J * DBA/2 Mating. AB - Immunological disorders are among the main causes of recurrent spontaneous abortions (RSAs). Mesenchymal stem cells (MSCs) have been shown to modulate various aspects of immune responses. It seems that MSCs may improve the immunological conditions in immune-mediated RSA. The aim of this study is the reduction of resorption in RSA mouse model through MSCs therapy. The adipose derived MSCs were administered intraperitoneal to pregnant CBA/J mice on day 4.5 of gestation in abortion-prone matting. On day 13.5 of pregnancy, abortion rates were calculated and transforming growth factor-beta (TGF-beta), interleukin 10 (IL-10), interferon gamma (IFN-gamma), and tumor necrosis factor alpha (TNF alpha) gene expression in deciduas were evaluated by real-time polymerase chain reaction (PCR). The level of TGF-beta in serum was also determined by enzyme linked immunosorbent assay (ELISA) method. The obtained results showed that MSCs therapy could reduce the abortion rate significantly in test group compared to controls. MSCs therapy also caused a significant upregulation of TGF-beta and IL 10 and downregulation of IFN-gamma and TNF-alpha genes expression in deciduas. However, the levels of TGF-beta didn't change in mice sera. Due to the significant decrease in abortion rate, we concluded that MSCs therapy could modulate the immune responses in fetomaternal interface and protect fetus from undesirable immune responses. So, these cells might be considered as a new therapeutic for spontaneous pregnancy loss. The local upregulation of TGF-beta and IL-10 and downregulation of IFN-gamma and TNF-alpha gene expression in decidua could be considered as one possible mechanism of immune regulation, which could protect the fetus. PMID- 29187059 TI - Bridging observational studies and randomized experiments by embedding the former in the latter. AB - Consider a statistical analysis that draws causal inferences from an observational dataset, inferences that are presented as being valid in the standard frequentist senses; i.e. the analysis produces: (1) consistent point estimates, (2) valid p-values, valid in the sense of rejecting true null hypotheses at the nominal level or less often, and/or (3) confidence intervals, which are presented as having at least their nominal coverage for their estimands. For the hypothetical validity of these statements, the analysis must embed the observational study in a hypothetical randomized experiment that created the observed data, or a subset of that hypothetical randomized data set. This multistage effort with thought-provoking tasks involves: (1) a purely conceptual stage that precisely formulate the causal question in terms of a hypothetical randomized experiment where the exposure is assigned to units; (2) a design stage that approximates a randomized experiment before any outcome data are observed, (3) a statistical analysis stage comparing the outcomes of interest in the exposed and non-exposed units of the hypothetical randomized experiment, and (4) a summary stage providing conclusions about statistical evidence for the sizes of possible causal effects. Stages 2 and 3 may rely on modern computing to implement the effort, whereas Stage 1 demands careful scientific argumentation to make the embedding plausible to scientific readers of the proffered statistical analysis. Otherwise, the resulting analysis is vulnerable to criticism for being simply a presentation of scientifically meaningless arithmetic calculations. The conceptually most demanding tasks are often the most scientifically interesting to the dedicated researcher and readers of the resulting statistical analyses. This perspective is rarely implemented with any rigor, for example, completely eschewing the first stage. We illustrate our approach using an example examining the effect of parental smoking on children's lung function collected in families living in East Boston in the 1970s.

PMID- 29187061 TI - Accuracy of Predictive Equations for Energy Expenditure in Mexicans Living With HIV/AIDS With and Without Antiretroviral Therapy. AB - INTRODUCTION: Determination of the resting energy expenditure (REE) is essential for planning nutrition therapy in patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) to help to improve their nutrition status. We aim to evaluate the agreement and accuracy of prediction equations that estimate the REE in a Mexican population with a diagnosis of HIV/AIDS with and without antiretroviral therapy (ART). METHODS: A cross sectional study in Mexican patients with HIV/AIDS with and without ART. Weight, height, and body composition measured with dual-energy x-ray absorptiometry were evaluated. The REE was determined with indirect calorimetry and estimated using the Mifflin-St Jeor (MSJ), Harris-Benedict (HB), Schofield 1 and 2, Cunningham, Melchior 91, Melchior 93, and Batterham equations. The Bland-Altman method assessed agreement between the real and estimated values, and the percent difference between these values was used to assess the prediction accuracy. RESULTS: Sixty-five adults without ART and 102 adults with ART were included. The mean REE (kcal/kg) was 24.8 +/- 2.4 and 23.8 +/- 3.6 in patients without and with ART, respectively. Good agreement and reliability were observed in the HB (intraclass correlation coefficient [ICC], 0.75; P < .05), Batterham (ICC, 0.79; P < .05), Schofield 1 (ICC, 0.74; P < .05), and Schofield 2 (ICC, 0.78; P < .05) results in individuals without ART. In individuals with ART, good agreement and reliability were observed with the HB equation (ICC, 0.76; P < .05). The MSJ equation showed good agreement with poor reliability (ICC, 0.05; P < .05). CONCLUSION: The equations with the best agreement and accuracy were Schofield 2, Batterham, and HB in individuals without ART and HB and MSJ in the population with ART.

AB - BACKGROUND: Home parenteral nutrition (PN) is a lifesaving therapy for children with intestinal failure (IF). Our aims were to describe the prevalence of micronutrient deficiencies (vitamin D, zinc, copper, iron, selenium) in a diverse population of children with IF receiving PN and to identify and characterize risk factors associated with micronutrient deficiencies, including hematologic abnormalities. METHODS: Data were collected on 60 eligible patients through retrospective chart review between May 2012 and February 2015. Descriptive statistics included frequencies, medians, interquartile ranges (IQRs), and odds ratios (ORs). Statistical analyses included chi2, Fisher's exact, t tests, and logistic, univariate, and multivariate regressions. RESULTS: Patients were primarily young (median age, 3.3 years; IQR, 0.7-8.4), Latino (62%), and male (56%), with short bowel syndrome (70%). Of 60 study patients, 88% had >=1 deficiency and 90% were anemic for age. Of 51 patients who had all 5 markers checked, 59% had multiple deficiencies (defined as >=3). Multivariate analysis shows multiple deficiencies were associated with nonwhite race (OR, 9.4; P = .012) and higher body mass index z score (OR, 2.2; P = .016). Children with severe anemia (hemoglobin <8.5 g/dL) made up 50% of the cohort. Nonwhite race (OR, 6.6; P = .037) and zinc deficiency (OR, 11; P = .003) were multivariate predictors of severe anemia. CONCLUSIONS: Micronutrient deficiency and anemia are overwhelmingly prevalent in children with IF using chronic PN. This emphasizes the importance of universal surveillance and supplementation to potentially improve quality of life and developmental outcomes. Future research should investigate how racial disparities might contribute to nutrition outcomes for children using chronic PN.

PMID- 29187065 TI - A Systematic Literature Review and Research Agenda for Organ Donation Decision Communication. AB - BACKGROUND: This study systematically located and appraised peer-reviewed evidence for the efficacy of strategies to increase organ donation decision communication among adults including an assessment of study quality to guide future research in this field. There is little room to move in strengthening unanimously positive public attitudes toward organ donation. Consequently, researchers have called for a focus on organ donation decision communication to understand modifiable factors to increase organ donation rates. METHODS: Multiple databases were searched during September 2015, and 44 studies were selected for inclusion. Data concerning participants, design, and outcomes were extracted. Studies were rated for quality and levels of evidence. FINDINGS: Although not amenable to meta-analysis, the literature indicates that approximately 50% of adults who are willing to become an organ donor have discussed this decision with family. The majority of research was conducted in a Western context with an overrepresentation of students. Strategies to increase communication include education, motivation, input from lived experience, efforts to address salient audience beliefs, and scheduled reminders or prompts. Intentions and willingness to discuss organ donation were consistently positively related to discussion behavior; however, formative research and experimental studies testing theoretically driven interventions were scarce. CONCLUSIONS: There is mixed evidence for the role of demographic and attitudinal characteristics in the success of organ donation communication interventions. Additional theoretically based research is recommended to establish boundary conditions and validate strategies to increase organ donation decision communication among adults. PMID- 29187066 TI - Pilot-scale sorption studies of diethylketone in the presence of Cd2+ and Ni2. AB - The effect of pH on the sorption capacity of vermiculite towards cadmium and nickel was tested in batch systems and it was shown that the sorption percentages increase with an increase in the mass of vermiculite and with an increase in the initial pH. Maximum sorption percentages were obtained for a pH of 8 and 4 g of vermiculite (86.5% for Cd2+ and 86.1% for Ni2+, for solutions with 100 mg/L of metal). As a consequence, it was possible to establish a range of optimal pH for biosorption processes, by combining the so determined optimal sorption pH of vermiculite with the optimal growth pH of Streptococcus equisimilis, a bacterium used to treat contaminated water. Pilot-scale experiments with a S. equisimilis biofilm supported on vermiculite were conducted in closed-loop conditions, aiming to treat large volumes of diethylketone aqueous solutions, eventually containing Cd2+ or Ni2+. The excellent capacity of this joint system to simultaneously biodegrade diethylketone and biosorb Cd2+ or Ni2+was proved. The removal percentage and the uptake increase through time, even with the replacement of the initial solution by new ones. The breakthrough curves that best describe the results achieved for Cd2+ and Ni2+ are respectively the Adams-Bohart and the Yoon and Nelson model. PMID- 29187067 TI - When people's judgments of learning (JOLs) are extremely accurate at predicting subsequent recall: the "Displaced-JOL effect". AB - Judgments of learning (JOL) made after a delay more accurately predict subsequent recall than JOLs made immediately after learning. One explanation is that delayed JOLs involve retrieving information about the target item from secondary memory, whereas immediate JOLs involve retrieval from primary memory. One view of working memory claims that information in primary memory is displaced to secondary memory when attention is shifted to a secondary task. Thus, immediate JOLs might be as accurate as delayed JOLs if an intervening task displaces the target item from primary memory, requiring retrieval from secondary memory, prior to making the JOL. In four experiments, participants saw related word-pairs and made JOLs predicting later recall of the item. In Experiment 1, delayed JOLs were more accurate than JOLs made shortly after learning, regardless of whether a secondary task intervened between learning and JOL. In Experiments 2-4, the secondary task demands increased and JOLs made shortly after learning with an intervening task were just as accurate as delayed JOLs, and both were more accurate than immediate JOLs with no intervening task (Experiment 4). These results are consistent with a retrieval-based account of JOLs, and demonstrate that the "delayed-JOL effect" can be obtained without a long delay. PMID- 29187068 TI - Environmental and economic benefits of the recovery of materials in a municipal solid waste management system. AB - The main aim of this study was to perform a Life cycle assessment study as well as an economic evaluation of the recovery of recyclable materials in a municipal solid waste management system. If citizens separate erroneously waste fractions, they produce both environmental and economic damages. The environmental and economic evaluation was performed for the case study of Nola (34.349 inhabitants) in Southern Italy, with a kerbside system that assured a source separation of 62% in 2014. The economic analysis provided a quantification of the economic benefits obtainable for the population in function of the achievable percentage of source separation. The comparison among the environmental performance of four considered scenarios showed that the higher the level of source separation was, the lower the overall impacts were. This occurred because, even if the impacts of the waste collection and transport increased, they were overcome by the avoided impacts of the recycling processes. Increasing the source separation by 1% could avoid the emission of 5 kg CO2 eq. and 5 g PM10 for each single citizen. The economic and environmental indicators defined in this study provide simple and effective information useful for a wide-ranging audience in a behavioural change programme perspective. PMID- 29187069 TI - Development of alpha- and gamma-Fe2O3 decorated graphene oxides for glyphosate removal from water. AB - In this study, the proposed adsorbent composed of graphene oxide (GO) functionalized by magnetic nanoparticles of iron oxide (alpha-gamma-Fe2O3) was obtained by a simple ultrasonication process. This new material was used for the removal of glyphosate in water. The nanoparticulated iron oxide used was synthesized by means of a modified sol-gel method, which does not use organic solvents. The adsorbent material (GO-alpha-gamma-Fe2O3) obtained was characterized by magnetic measurements, and it can be proved that it has superparamagnetic properties, allowing fast and efficient magnetic separation. The equilibrium time for the adsorption of glyphosate when using GO-alpha-gamma Fe2O3 was 2 hours and the maximum removal was 92% at 15 degrees C, with a maximum adsorption capacity of 46.8 mg g-1. Langmuir model and pseudo-second-order kinetic model correlated satisfactorily to the experimental data. The thermodynamic parameters showed that the adsorption of glyphosate on GO-alpha gamma-Fe2O3 was spontaneous, exothermic and thermodynamically favorable at temperature of 15-45 degrees C. Thus the adsorbent material GO-alpha-gamma-Fe2O3 proposed in this study is considered a good candidate to be used in the removal of glyphosate from aqueous solutions, presenting high adsorption capacity, low cost and magnetic properties that facilitate the separation of the adsorbent material. PMID- 29187070 TI - Loading efficacy and binding analysis of retinoids with milk proteins: a short review. AB - In this review, the loading efficacies of retinoids with milk proteins are investigated. It has been shown that milk proteins beta-lactoglobulin, alpha-, and beta-caseins bind retinol and retinoic acid via hydrophobic, hydrophilic, and H-bonding contacts causing minor alterations of protein secondary structure. Hydrophobic contact is predominant in retinoid-protein conjugation and several amino acids are involved in complex formation, stabilized by H-bonding network. Loading efficacy of retinoid was about 30-50% with retinol forming more stable protein conjugates. Milk proteins can transport retinoid to target molecules. PMID- 29187071 TI - Endovascular Stent Can Be the Treatment of Choice for Spontaneous Iliac Vein Rupture: A Case Report. AB - INTRODUCTION: Spontaneous iliac vein rupture is a rare but lethal disease. Most patients suffer from shock status in the emergency department. Until now, open laparotomy combined with primary suture is the most common treatment of iliac vein rupture. However, there is high mortality and morbidity in the patients who underwent open laparotomy. CASE PRESENTATION: A 71-year-old woman denied trauma history and sustained hypovolemic shock. The abdominal computed tomography showed one huge retroperitoneal hematoma. The emergency angiography revealed one obvious rupture point on the left external iliac vein. We repaired the lesion with endovascular stent and open laparotomy for abdominal decompression. The patient progressed well and was discharged. CONCLUSION: Endovascular repair is an effective and safe treatment. Compared with open laparotomy and primary suture, stent leads to fewer complications and a lower mortality rate. PMID- 29187072 TI - Understanding the growth of the bio-struvite production Brevibacterium antiquum in sludge liquors. AB - Biological struvite (bio-struvite) production through biomineralization has been suggested as an alternative to chemically derived struvite production to recover phosphorus from wastewater streams. In this study, statistical experimental design techniques were used to find the optimal growth rate (MU) of Brevibacterium antiquum in sludge liquors. Acetate, oleic acid, NaCl, NH4-N, and Ca2+ were shown to affect the growth rate of B. antiquum. The growth rate reached 3.44 1/d when the bacteria were supplemented with 3.0% w/v NaCl and 1124 mg chemical oxygen demand/L as acetate. However, NaCl was found to hinder the biomineralization of bio-struvite. A two-stage experiment demonstrated that bio struvite was produced in the presence of acetate. Bio-struvite production was confirmed with X-ray spectroscopy and crystal morphology (prismatic, tabular, and twinned crystal habit) through electron microscope analysis. The bio-struvite production was estimated by measuring phosphate content of the recovered precipitates, reaching 9.6 mg P/L as bio-struvite. Overall, these results demonstrated the optimal conditions required to achieve high growth rates as well as bio-struvite production with B. antiquum. The results obtained in this study could be used to develop a process to grow B. antiquum in wastewater streams in mixed cultures and recover phosphorus-rich products such as struvite. PMID- 29187073 TI - Elevation of intracellular calcium and oxidative stress is involved in perfluorononanoic acid-induced neurotoxicity. AB - Perfluorononanoic acid (PFNA) is one of the major perfluorinated compounds found in both biological and abiotic samples and has recently been demonstrated to cause neurobehavioral defects in mammals. In this study, pheochromocytoma-12 (PC12) cells were exposed to various doses of PFNA to explore the cytotoxicity of PFNA to neurons and the possible mechanisms underlying these effects. The results showed that exposure to PFNA dose-dependently decreased the viability of PC12 cells and increased the release of lactate dehydrogenase into cell culture media. Exposure to PFNA increased the malondialdehyde content and decreased the total antioxidant capacity and glutathione peroxidase activity in PC12 cell culture supernatants. Exposure to PFNA increased the intracellular calcium level and upregulated the Ca2+/calmodulin-dependent protein kinase II (CaMKII) expression in PC12 cells. PFNA also decreased Bcl-2 expression and increased Bax expression in PC12 cells. These results suggested that exposure to PFNA elevated the intracellular calcium level and activated the CaMKII signaling pathway, which may aggravate oxidative stress in PC12 cells and lead to cell damage or cell apoptosis. PMID- 29187074 TI - Long-term dynamics of the bacterial community in a Swedish full-scale wastewater treatment plant. AB - The operational efficiency of activated sludge wastewater treatment plants depends to a large extent on the microbial community structure of the activated sludge. The aims of this paper are to describe the composition of the bacterial community in a Swedish full-scale activated sludge wastewater treatment plant, to describe the dynamics of the community and to elucidate possible causes for bacterial community composition changes. The bacterial community composition in the activated sludge was described using 16S rRNA gene libraries and monitored for 15 months by a terminal restriction fragment (T-RF) length polymorphism (T RFLP) analysis of the 16S rRNA gene. Despite variable environmental conditions, a large fraction of the observed T-RFs were present at all times, making up at least 50% in all samples, possibly representing a relatively stable core fraction of the bacterial community. However, the proportions of the different T-RFs in this fraction as well as the T-RFs in the more variable fraction showed a significant variation over time and temperature. The difference in community composition between summer and winter coincided with observed differences in floc structure. These observations suggest a relationship between floc properties and bacterial community composition, although additional experiments are required to determine causality. PMID- 29187075 TI - Retention in Care among Patients with Early HIV Disease in Haiti. AB - In September 2015, the World Health Organization updated their guidelines to recommend antiretroviral therapy (ART) for all people living with HIV. Countries are now in the process of implementing strategies to provide universal HIV treatment. We analyzed the rate of retention and time to ART eligibility (according to 2013 WHO guidelines) among 3,345 adult patients receiving positive HIV test results between February 1, 2003 and March 31, 2013 at the GHESKIO Clinic in Haiti, with WHO stage 1 or 2 disease and initial CD4 cell count >500 cells/mm3. Among the 3,345 patients, 2,423 (72%) were female, the median age was 33 years, 3,089 (92%) lived in Port-au-Prince, and 1,944 (58%) had attended no school or primary school only. The median initial CD4 cell count was 668 cells/mm3 (IQR: 572-834); over the subsequent 2 years, 1,485 patients (44%) were lost to follow-up and 7 (<1%) died pre-ART, 1,041 (31%) were retained in pre-ART care, and 819 (24%) initiated ART. In multivariate analysis, secondary education (aOR 1.27; 95% CI: 1.10-1.47), female gender (aOR: 1.28; 95% CI: 1.09-1.50), co habitation (aOR: 1.31; 95% CI: 1.09-1.57), and residence in Port-au-Prince (aOR: 1.43; 95% CI: 1.09-1.88) were associated with retention in care. The median time from baseline CD4 count to ART eligibility was 1.7 years. Prior to the implementation of universal treatment, pre-ART attrition was high among patients who did not qualify for ART at presentation. Though implementing WHO recommendations for universal ART will require service expansion, it will likely result in improved retention for those at risk of being lost to follow-up. PMID- 29187076 TI - Clinicoepidemiological Profile of Elderly PLHIV Attending a Tertiary Care Center in South India. AB - BACKGROUND: Physicians are coming across a considerable number of HIV-positive patients belonging to older age-group, in practice. They pose a challenge as they might present with advanced forms and comorbid conditions. We aimed to describe the clinicoepidemiological profile of elderly people living with HIV. METHODOLOGY: We conducted a cross-sectional study at Kasturba Medical College, Mangalore. We analyzed the record of 120 patients from 2009 to 2014. Descriptive statistics were used to describe sociodemographic and clinical profile of patients. RESULTS: Of 786 HIV-positive patients, 120 were elderly. Mean age was 55.9 +/- 6.1 years. Majority 68% were male. In all, 63.33% were male. Commonest route of transmission was heterosexual intercourse, most presented at World Health Organization (WHO) stage 1 (64.17%). In all, 77.5% had hypertension and 26.6% had tuberculosis. The median CD4 count at presentation was 245 cells/mm3 (145-426 cells/mm3). Forty-two percent were late presenters (CD4 <200 cells/mm3). CONCLUSION: Treating physician should have a high index of suspicion in diagnosing HIV among elderly age-group. PMID- 29187078 TI - Maternal fluoride exposure during gestation and lactation decreased learning and memory ability, and glutamate receptor mRNA expressions of mouse pups. AB - Previous investigations demonstrated that high fluoride (F) exposure may adversely affect the neurodevelopment and learning and memory ability. However, whether maternal F exposure during gestation and lactation can influence the learning, memory ability, and glutamate receptor expressions of offspring has not yet been elucidated. Hence, in the present study, maternal mice were exposed to F (25, 50, or 100 mg/L sodium fluoride (NaF) in drinking water) during gestation and lactation. Results showed that exposure to 100 mg/L NaF significantly enhanced the number of total arm entries and working memory errors of offspring in the radial arm maze test compared to the control group. However, no difference was observed in open-field behaviors. For the subtypes of glutamate receptors in hippocampus, expression of GluR2 mRNA was significantly reduced by 25, 50, and 100 mg/L NaF. Besides, F exposure also suppressed the expression of NR2A, NR2B, and mGluR2 mRNA levels in a dose-dependent manner, where NR2A was significantly suppressed by 50 mg/L NaF and NR2B and mGluR2 by 100 mg/L NaF. However, no significant changes were observed in GluR1 and mGluR5 mRNA expression levels. Collectively, these findings suggested that F can pass through the cord blood and breast milk and may have deleterious impact on learning and memory of the mouse pups, which was mediated by reduced mRNA expression of glutamate receptor subunits. PMID- 29187077 TI - HIV-Related Knowledge among PLWHA Attending a Tertiary Care Hospital at Coastal South India-A Facility-Based Study. AB - BACKGROUND: Adequate knowledge about HIV/AIDS among people living with HIV (PLHIV) is essential for the prevention of HIV transmission. METHODS: A cross sectional study consisting of 409 PLHIV aged >=18 years were interviewed regarding their HIV-related knowledge, from April 2014 to April 2015. HIV-related knowledge was assessed using the HIV knowledge questionnaire 18 . Univariate and multivariate analyses were done to determine the factors associated with high HIV related knowledge. Odds ratios with its corresponding 95% confidence intervals were reported. A value of P < .05 was considered to be statistically significant. RESULTS: Among 409 PLHIV, 46.2% had high HIV-related knowledge. Univariate analysis yields factors like upper socioeconomic status, those who are literates, unemployed, and adherent to antiretroviral therapy (ART) were associated with higher HIV-related knowledge. On multivariate analysis, upper socioeconomic status and adherence to ART were the factors that remained significantly associated with higher HIV-related knowledge. CONCLUSION: HIV-related knowledge among PLHIV can be improved through HIV educational programs. PMID- 29187079 TI - Anti-inflammatory, antioxidant and anti-apoptotic activity of diosmin in acetic acid-induced ulcerative colitis. AB - : Ulcerative colitis (UC) is a chronic inflammatory disease affecting colon. The primary symptoms of UC are diarrhoea with blood and mucus and sometimes associated with pain. AIM: This study aimed to evaluate the effects of diosmin (DIO) on UC. METHODS: UC was induced in rats by rectal administration of acetic acid (AA). The degree of mucosal ulceration and damage was determined by evaluating the disease activity index (DAI) and colon damage index scores. Inflammation, oxidative stress and apoptotic responses were determined by measuring the levels of tumour necrosis factor-alpha (TNF-alpha), cyclooxygenase 2 (COX-II), malondialdehyde (MDA) and reduced glutathione (GSH) in addition to myeloperoxidase (MPO) activity and caspase-3 expression. RESULTS: The results of this study indicate that AA caused increase in DAI and colon damage index scores. Also, markers of inflammation (TNF-alpha, COX-II and MPO) and oxidative stress (MDA and reduced GSH) were significantly elevated. These changes were associated with increases in colon caspase-3 expression. Treatment of rats with two doses of DIO produced a dose-dependent decline in DAI and colon damage index scores. Also, DIO resulted in significant reduction of inflammatory and oxidative stress markers as well as reduced the expression of caspase-3. CONCLUSION: DIO therapy decreased UC development depending on its ability to decreases inflammation, oxidative stress and apoptosis in rat colon. PMID- 29187080 TI - "Strange animals": hybrid organisations in health care. AB - Purpose The purpose of this paper is to critically explore hybrid organisations in health care. It examines the broad literature on hybrids focusing on issues of perspective, definition, sub-type and level. It then presents the results of the literature review of hybrid health care organisations, exploring which organisations have been viewed as hybrids, and then examining studies in more detail with respect to the research questions. Design/methodology/approach It critically explores the literature on hybrid organisations in health care through a structured search. Findings It is found that a wide variety of hybrid forms exist, but not clear what they combine or how they combine it. However, the level of depth from some of these studies is rather limited, with little consensus on definition, and relatively few drawing on any explicit conceptual perspective. It seems that the wider hybridity literatures have limited influence of studies of hybrid health care organisations. Originality/value As far as the authors are aware, this paper is the first attempt to critically review the literature on hybrid organisations in health care. It is concluded that it is difficult to define and explain hybrid health care organisations. Health care hybrids appear to be chameleons as they appear to be able to change their form to different observers. PMID- 29187081 TI - Medical directors' perspectives on strengthening hospital quality and safety. AB - Purpose The purpose of this paper is to understand the concerns and factors that impact on hospital quality and safety, particularly related to use of performance data, within a setting of devolved governance. Design/methodology/approach This qualitative study used thematic analysis of interviews with public hospital medical directors. For additional context, findings were framed by themes from a review of hospital safety and quality in the same jurisdiction. Findings Varying approaches and levels of complexity were described about what and how performance data are reviewed, prioritised, and quality improvements implemented. Although no consistent narrative emerged, facilitators of improvement were suggested relating to organisational culture, governance, resources, education, and technologies. These hospital-level perspectives articulate with and expand on the system-level themes in a state-wide review of hospital safety and quality. Research limitations/implications The findings are not generalisable, but point to an underlying absence of system-wide agreement on how to perceive, retrieve, analyse, prioritise and action hospital performance data. Practical implications Lack of electronic medical records and an inefficient incident reporting system limits the extent to which performance and incident data can be analysed, linked and shared, thus limiting hospital performance improvement, oversight and learning. Social implications Variable approaches to quality and safety, standards of care, and hospital record keeping and reporting, mean that healthcare consumers might expect inconsistency across Victorian hospitals. Originality/value The views of medical directors have been little researched. This work uses their voice to better understand contextual factors that situate and impact on hospital quality and safety towards understanding the mixed effectiveness of hospital quality improvement strategies. PMID- 29187082 TI - Lean leadership attributes: a systematic review of the literature. AB - Purpose Emphasis on quality and reducing costs has led many health-care organizations to reconfigure their management, process, and quality control infrastructures. Many are lean, a management philosophy with roots in manufacturing industries that emphasizes elimination of waste. Successful lean implementation requires systemic change and strong leadership. Despite the importance of leadership to successful lean implementation, few researchers have probed the question of ideal leadership attributes to achieve lean thinking in health care. The purpose of this paper is to provide insight into applicable attributes for lean leaders in health care. Design/methodology/approach The authors systematically reviewed the literature on principles of leadership and, using Dombrowski and Mielke's (2013) conceptual model of lean leadership, developed a parallel theoretical model for lean leadership in health care. Findings This work contributes to the development of a new framework for describing leadership attributes within lean management of health care. Originality/value The summary of attributes can provide a model for health-care leaders to apply lean in their organizations. PMID- 29187083 TI - Overcoming counter-knowledge through telemedicine communication technologies. AB - Purpose Knowledge acquired from sources of unverified information such as gossip, partial truths or lies, in this paper it is termed as "counter-knowledge." The purpose of this paper is to explore this topic through an exploration of the links between a Hospital-in-the-Home Units (HHUs) learning process (LP), counter knowledge, and the utilization of communication technologies. The following two questions are addressed: Does the reduction of counter-knowledge result in the utilization of communication technologies? Does the development of counter knowledge hinder the LP? Design/methodology/approach This paper examines the relevance of communication technologies to the exploration and exploitation of knowledge for 252 patients of a (HHU) within a Spanish regional hospital. The data collected was analyzed using the PLS-Graph. Findings To HHU managers, this study offers a set of guidelines to assist in their gaining an understanding of the role of counter-knowledge in organizational LPs and the potential contribution of communication technologies. Our findings support the proposition that the negative effects of counter-knowledge can be mitigated by using communication technologies. Originality/value It is argued in this paper that counter-knowledge may play a variety of different roles in the implementation of LPs. Specifically, the assignment of communication technologies to homecare units has given them the means to filter counter-knowledge and prevent users from any possible problems caused by such counter-knowledge. PMID- 29187084 TI - Do different approaches to clinical governance development and implementation make a difference? Findings from Ireland and New Zealand. AB - Purpose Clinical governance (CG) is an important foundation for a high-performing health care system, with many countries supporting its development. CG policy may be developed and implemented nationally, or devolved to a local level, with implications for the overall approach to implementation and policy uptake. However, it is not known whether one of these two approaches is more effective. The purpose of this paper is to probe this question. Its setting is Ireland and New Zealand, two broadly comparable countries with similar CG policies. Ireland's was nationally led, while New Zealand's was devolved to local districts. This leads to the question of whether these different approaches to implementation make a difference. Design/methodology/approach Data from surveys of health professionals in both countries were used to compare performance with CG development. Findings The study showed that Ireland's approach produced a slightly better performance, raising questions about the merits of devolving responsibility for policy implementation to the local level. Research limitations/implications The Irish and New Zealand surveys both had lower-than desirable response rates, which is not uncommon for studies of health professionals such as this. The low response rates mean the findings may be subject to selection bias. Originality/value Despite the importance of the question of whether a national or local approach to policy implementation is more effective, few studies specifically focus on this, meaning that this study provides a new contribution to the topic. PMID- 29187085 TI - Caring for Dying Patient and Their Families: The Lived Experiences of Nursing Students in Italy. AB - BACKGROUND: The literature from recent decades persistently suggests that nurses are not adequately trained in caring for the dying. Numerous studies call for enhanced education in end-of-life care. OBJECTIVE: To explore student nurses' experience of caring for dying persons and their families and how this experience was influenced by their undergraduate education, with a view to improving end-of life training. METHODS: Narrative interviews were administered to a purposive sample of 18 undergraduate students at Turin University's School of Nursing and analyzed following Giorgi's qualitative phenomenological methodology. RESULTS: The students' accounts featured 4 main themes: emotions and feelings, reactions and coping strategies, growth in personal and professional awareness, and the professional nursing model. Students reporting positive experience of end-of-life care in clinical settings displayed the expected learning outcomes for undergraduate nursing education. CONCLUSION: This study's strength lies in the fact that it draws on student nurses' lived experience to assess training in end of-life care. It confirms the need to invest in targeted end-of-life education and support for nursing students. PMID- 29187086 TI - Nutrition Management of Home Parenteral Nutrition Among Patients With Enterocutaneous Fistula in the Sustain Registry. AB - BACKGROUND: Home parenteral nutrition (HPN) is a vital therapy for patients who have the diagnosis of enterocutaneous fistula (ECF), yet little is known about how these patients are managed. This research compares nutrition management of adults with ECF as the indication for HPN therapy to those with other indications. METHODS: This is an analysis of data from adult HPN patients in the Sustain registry enrolled between August 2011 and February 2014 who have the diagnosis of ECF or other indication for HPN who served as the control group. Differences between the ECF and control group were assessed by t test, analysis of variance, or chi2 as appropriate. RESULTS: There were 141 HPN patients with ECF and 632 control patients. Patients with ECF were older (55 vs 50 years, P < .001), more frequently had a goal for future surgery (30% vs 15%, P = .010), had greater prevalence of overweight/obesity (33% vs 20%, P = .04), and had a lower serum albumin (2.98 +/- 0.65 g/dL vs 3.16 +/- 0.66 g/dL, P = .006) than controls. The diet order was more frequently nil per os (NPO) in patients with ECF (48% vs 22%, P < .001), and amino acid content of HPN was greater (111.90 +/- 29.11 vs 102.06 +/- 27.84, P < .001) than in controls. There were no differences in patterns of weight change by ECF or control groups, although underweight patients gained, normal-weight patients maintained, and overweight/obese patients lost weight and serum albumin increased similarly. CONCLUSIONS: The HPN management of patients with ECF is similar to other HPN patients other than greater provision of protein, more frequent NPO status, and a goal for future surgery.

AB - Relapsing polychondritis is a rare multisystem autoimmune disease characterized by recurrent inflammation and destruction of different cartilaginous and proteoglycan-rich structures like cardiovascular system. We reported a case of heart transplantation in a 20-year-old man having a relapsing polychondritis with severe multiple cardiovascular involvement. The immunosuppressive treatment used to prevent graft rejection allowed to turn out the inflammatory disease. Cardiac transplantation may be considered as last resort treatment option in relapsing polychondritis with intractable extensive heart lesions. PMID- 29187088 TI - European Vignettes in Donation After Circulatory Death. AB - Donation after circulatory death (DCD) is increasing in Europe, yet there is widespread variability in practice. Insight into actual practice is difficult to acquire simply by analyzing protocols and laws from each individual country. For this reason, the 3 DCD vignettes in this article have been constructed to outline routine and standard DCD practice in the United Kingdom, the Netherlands, and Spain. These imagined vignettes reflect a "typical" case, based on the authors' extensive experience with DCD but are not real patient cases. They are a resource aimed at stimulating discussion regarding European organ donation practice and provide a knowledge bank for those wanting to establish a DCD program in their country. It is our hope that by providing these vignettes, the wider organ donation and transplant community, as well as philosophers and the public, will have a better understanding of what DCD really is and what it really isn't. PMID- 29187089 TI - Pyridoxine Deficiency After Solid Organ Transplant. AB - OBJECTIVE: Pyridoxine is 1 of 8 B vitamins that assist in a variety of essential functions including immune functions. The purpose of this study was to assess the risk factors associated with low pyridoxine levels in solid organ transplantation recipients. DESIGN: The study cohort was divided into 2 groups: (a) patients with normal pyridoxine levels or (b) patients with low pyridoxine levels. Dietary evaluation and clinical characteristics of all patients, rejection episodes, and immunosuppression were collected. Simple descriptive statistics were used to analyze the overall cohort. RESULTS: Of the 48 patients, 29 (60%) in the study cohort were identified to have low pyridoxine levels. The mean interval between transplantation and pyridoxine level check was 910 days (standard deviation [SD] 456). The mean weight at the time of dietary consultation was 80 kg (SD 20.7). More patients in the deficient group received thymoglobulin for rejection treatment (56% vs 0%; P = .01) and were thymoglobulin recipients (78% vs 10%; odds ratio [OR] = 31.5; 95% confidence interval [CI], 2.35-422.30; P < .01). A strong correlation was identified between thymoglobulin treatment for induction and a low level of pyridoxine (correlation coefficient R = 0.6, P = .004) and between thymoglobulin treatment for rejection and a low pyridoxine level (correlation coefficient R = 0.5, P = .05). Based on multivariate logistic regression analysis, only thymoglobulin treatment (induction or rejection treatment) was significantly associated with low pyridoxine levels (OR = 19.5, 95% CI, 1.01-375.24; P < .05). CONCLUSIONS: Low levels of pyridoxine appear to be relatively common, and thymoglobulin treatments are associated with low pyridoxine levels. Prospective studies are needed to confirm and valuate the significance of these findings. PMID- 29187090 TI - Outcomes of Patients With Familial Transthyretin Amyloidosis After Liver Transplantation. AB - BACKGROUND: Familial transthyretin amyloidosis is a disease caused by misfolded transthyretin aggregates that can impair multiple organ systems. Liver transplantation is the first-line treatment for familial transthyretin amyloidosis. RESEARCH QUESTION: Our objective is to study outcomes and survival among patients with familial transthyretin amyloidosis after transplantation. DESIGN: All patients undergoing orthotopic liver transplant for familial transthyretin amyloidosis at Mayo Clinic between 1997 and 2012 were reviewed. Baseline clinical characteristics, organs transplanted, and posttransplant clinical course were assessed. RESULTS: Of the 40 patients, 7 patients had the V30M mutation and 33 had other mutations. Nineteen patients received liver only, 19 liver and heart, and 2 combined liver, heart, and kidney transplants. The 5 year overall survival was 85% for those receiving multiple organ transplant and 52% for those receiving liver transplant only ( P = .057). There was no difference in overall survival based on mutation (V30M vs other mutations), but survival was confounded by varied disease involvement and organs transplanted. Those who had early death (<=24 months from liver transplant) had a higher incidence of baseline peripheral neuropathy, autonomic neuropathy, lower modified BMI, and higher alkaline phosphatase. DISCUSSION: Outcomes of orthotopic liver transplant in familial transthyretin amyloidosis are variable due to heterogeneity in mutations and patient status at the time of transplant. Familial transthyretin amyloidosis can progress, despite liver transplantation. Patients receiving combined liver, heart/kidney transplant demonstrated improved survival compared to liver transplant alone.

PMID- 29187093 TI - A Standardized Framework for Transplant-Specific Competencies for Dietitians. AB - Dietitians have extensive training and are considered the experts in medical nutrition therapy (MNT). Although dietitian competencies for MNT are well established, competencies that account for the expanded roles of dietitians working in transplantation have not been developed. These expanded roles require a better understanding of transplant processes, regulations, and even the business side of transplant, novel concepts to most dietitians. Therefore, we proposed a standardized framework of transplant-specific competencies for dietitians practicing in transplantation. These competencies can help improve and standardize initial and ongoing training for transplant dietitians moving forward, ultimately leading to improved patient care for transplant candidates, recipients, and donors. PMID- 29187094 TI - Organ Donation Registration and Decision-Making Among Current Blood Donors in the Netherlands. AB - INTRODUCTION: In the Netherlands, there is a constant shortage in donor organs, resulting in long waiting lists. The decision to register as organ donor is associated with several demographic, cultural, and personal factors. Previous research on attitudes and motivations toward blood and organ donations provided similar results. RESEARCH QUESTION: The current study investigated demographic, cultural, and personal determinants of organ donation registration among current Dutch blood donors. DESIGN: We used data from Donor InSight (2012; N = 20 063), a cohort study among Dutch blood donors, to test whether age, gender, religious and political preferences, donor attitude, and altruism predicted organ donor registration among current blood donors. RESULTS: Organ donors were more often represented in the blood donor population compared to the general Dutch population. Women showed a higher propensity to be registered as organ donor. Higher education as well as higher prosocial value orientation, prosocial behavior, that is, doing volunteer work, and awareness of need significantly associated with being registered as organ donor. Religious denomination negatively predicted organ donation registration across all faiths. DISCUSSION: Results are discussed in light of cultural context, and possible implications for improving information provision and recruitment are mentioned. PMID- 29187095 TI - A Systematic Narrative Review of Effects of Community-Based Intervention on Rates of Organ Donor Registration. AB - BACKGROUND: The demand for organ donation is increasing worldwide. One possible way of increasing the pool of potential posthumous donors is to encourage more members of the general public to join an organ donor registry. OBJECTIVE: A systematic review was conducted to investigate the effectiveness of psychological interventions designed to increase the number of individuals in the community who register as organ donors. METHODS: PsycINFO and PubMed databases were searched. No date limits were set. Randomized and nonrandomized controlled trials exploring the effects of community-based interventions on organ donor registration rates were included. Methodological quality was assessed using the "Quality Assessment Tool for Quantitative Studies." RESULTS: Twenty-four studies met the inclusion criteria; 19 studies found a positive intervention effect on registration. Only 8 studies were assessed as having reasonable methodological robustness. A narrative synthesis was conducted. Factors influencing registration rates include providing an immediate registration opportunity and using brief interventions to challenge misconceptions and concerns about organ donation. DISCUSSION: Community-based interventions can be effective at increasing organ donor registrations among the general public. Factors that may increase effectiveness include brief interventions to address concerns and providing an immediate registration opportunity. Particular consideration should be paid to the fidelity of intervention delivery. Protocol registration number: CRD42014012975. PMID- 29187096 TI - Survey of Living Organ Donors' Experience and Directions for Process Improvement. AB - INTRODUCTION: Understanding living organ donors' experience with donation and challenges faced during the process is necessary to guide the development of effective strategies to maximize donor benefit and increase the number of living donors. METHODS: An anonymous self-administered survey, specifically designed for this population based on key informant interviews, was mailed to 426 individuals who donated a kidney or liver at our institution. Quantitative and qualitative methods including open and axial coding were used to analyze donor responses. FINDINGS: Of the 141 survey respondents, 94% would encourage others to become donors; however, nearly half (44%) thought the donation process could be improved and offered numerous suggestions. Five major themes arose: (1) desire for greater convenience in testing and scheduling; (2) involvement of previous donors throughout the process; (3) education and promotion of donation through social media; (4) unanticipated difficulties, specifically pain; and (5) financial concerns. DISCUSSION: Donor feedback has been translated into performance improvements at our hospital, many of which are applicable to other institutions. Population-specific survey development helps to identify vital patient concerns and provides valuable feedback to enhance the delivery of care.

AB - CONTEXT: Examination of efficacy of motor vehicle representative educational training and dissemination of promotional materials as a means to promote organ donation enrollments in New York State. OBJECTIVE: To increase the number of New York State residents who consent to donation through the department of motor vehicle transactions during project period. SETTING: County-run motor vehicle offices across New York State. PARTICIPANTS: Customers who present to New York Department of Motor Vehicle offices and the representative who work at designated bureaus. INTERVENTIONS: point-of-decision materials including promotional posters, brochures, website, and the motor vehicle representative training sessions. MAIN OUTCOME MEASURES: Reasons for enrollment decision, knowledge/experience with donation, monthly consent rates, enrollment in state organ, and tissue registry. RESULTS: Customers who elected not to register reported no reason or uncertainty surrounding enrollment. The representatives reported experience with donation, discussion with customers, and need for additional education on organ donation. Enrollment cards were mailed to 799 project staff; counties where offices participated in intervention did not indicate significantly higher monthly enrollments when comparing pre- to postenrollment rates. CONCLUSIONS: Use of point-of-decision materials and enrollment cards proved inexpensive method to register customers with a 3.6% return rate. Customers report low (27%) enrollment rate and reticence to consent to donation. Educational training sessions with representatives did not yield significant enrollment increases when evaluating data at county-level enrollment. PMID- 29187098 TI - Significantly Higher Mortality Following Liver Transplantation Among Patients Aged 70 Years and Older. AB - INTRODUCTION: The age of liver transplantation recipients in the United States is steadily increasing. However, the impact of age on liver transplant outcomes has demonstrated contradictory results. RESEARCH QUESTIONS: We aim to evaluate the impact of age on survival following liver transplantation among US adults. DESIGN: Using data from the United Network for Organ Sharing registry, we retrospectively evaluated all adults undergoing liver transplantation from 2002 to 2012 stratified by age (aged 70 years and older vs aged <70 years), presence of hepatocellular carcinoma, and hepatitis C virus status. Overall survival was evaluated with Kaplan-Meier methods and multivariate Cox proportional hazards models. RESULTS: Compared to patients aged <70 years, those aged 70 years and older had significantly lower 5-year survival following transplantation among all groups analyzed (hepatocellular carcinoma: 59.9% vs 68.6%, P < .01; nonhepatocellular carcinoma: 61.2% vs 74.2%, P < .001; hepatitis C: 60.7% vs 69.0%, P < .01; nonhepatitis C: 62.6% vs 78.5%, P < .001). On multivariate regression, patients aged 70 years and older at time of transplantation was associated with significantly higher mortality compared to those aged <70 years (hazards ratio: 1.67; 95% confidence interval: 1.48-1.87; P < .001). CONCLUSION: The age at the time of liver transplantation has continued to increase in the United States. However, patients aged 70 years and older had significantly higher mortality following liver transplantation. These observations are especially important given the aging cohort of patients with chronic liver disease in the United States. PMID- 29187099 TI - In Memoriam: Gordon K. Danielson (1931-2017).

AB - BACKGROUND: Congenital heart defects (CHDs) are common birth defects with significant impact on morbidity and mortality. We aimed to compare regional patterns of CHDs in Nigeria using a registry-based approach. METHODS: Children with echocardiography-confirmed CHDs at 17 medical centers across the country were enrolled in a pilot National Pediatric Cardiac Registry from January to December 2014. RESULTS: A total of 1,296 children (52.9% male; median age 0.9 years) with CHDs were enrolled. Patients enrolled in Northern Nigeria constituted 34.6% of the study population and were older compared to those enrolled from Southern Nigeria (2.9 +/- 3.6 vs 2.4 +/- 3.5 years; P = .02). Ventricular septal defects were significantly more prevalent in the North (37.4%) compared with the South (18.5%; P < .0001), while severe CHDs were more prevalent in the South ( P = .004). Of the 208 (16.0%) children who received corrective cardiac intervention, only 43 (20.7%) of them had the intervention done in country. More patients in the South received intervention compared to the North (19.02% vs 10.5%; P < .0001). CONCLUSION: This is the first prospective, registry-based, multicenter study of CHDs in Nigerian children. We demonstrate important differences between the Northern and the Southern geographical regions of the country in terms of age at diagnosis, type, and severity of lesion as well as access to cardiac surgery. The findings demonstrate the utility of a national CHDs registry for understanding clinical epidemiology of CHDs in low- and middle income countries and its potential to serve as a basis for research and planning. PMID- 29187102 TI - Education and Training in Pediatric Cardiac Critical Care. AB - Pediatric cardiac critical care is a new and emerging field. There is no standardization to the current education provided, and high-quality patient outcomes require such standardization. For physicians, this includes fellowship training, specific competencies, and a certification process. For advanced practice providers, a standardized curriculum as well as a certification process is needed. There is evidence that supports a finding that critical care nursing experience may have a positive impact on outcomes from pediatric cardiac surgery. A rigorous orientation and meaningful continuing education may augment that. For all disciplines and levels of expertise, simulation is a useful modality in the education in pediatric cardiac critical care. PMID- 29187103 TI - Development and Evaluation of a Continuing Education Program for Nursing Technicians at a Pediatric Cardiac Intensive Care Unit in a Developing Country. AB - BACKGROUND: The nursing profession faces continuous transformations demonstrating the importance of professional continuing education to extend knowledge following technological development without impairing quality of care. Nursing assistants and technicians account for nearly 80% of nursing professionals in Brazil and are responsible for uninterrupted patient care. Extensive knowledge improvement is needed to achieve excellence in nursing care. The objective was to develop and evaluate a continuing education program for nursing technicians at a pediatric cardiac intensive care unit (PCICU) using a virtual learning environment entitled EDUCATE. METHODS: From July to September 2015, a total of 24 nursing technicians working at the PCICU at a children's hospital located in the northwestern region of Sao Paulo state (Brazil) fully participated in the continuing education program developed in a virtual learning environment using Wix platform, allowing access to video classes and pre- and post-training theoretical evaluation questionnaires outside the work environment. The evaluation tools recorded participants' knowledge evolution, technological difficulties, educational, and overall rating. RESULTS: Knowledge development was descriptively presented as positive in more than 66.7%. Content and training were considered "excellent" by most participants and 90% showed an interest in the use of technological resources. Technical difficulties were found and quickly resolved by 40% of participants including Internet access, login, and lack of technical expertise. CONCLUSION: The continuing education program using a virtual learning environment positively contributed to the improvement in theoretical knowledge of nursing technicians in PCICU.

AB - BACKGROUND: Immune abnormalities are common in Fontan patients with protein losing enteropathy. Limited data exist on immune function of other patients with single ventricle circulation. METHODS: This prospective cohort study evaluated immunologic characteristics of children with single ventricle circulation from neonatal age up to early post-Fontan period. RESULTS: Low leukocyte counts were observed in half of the patients prior to bidirectional Glenn and Fontan surgery. Total lymphocyte counts were below normal range in 36% to 63% of patients across all groups except patients following Fontan procedure who had normal counts. Typical lymphocyte subpopulation patterns were (1) high counts of total and helper T lymphocytes (CD3+ and CD4+ cells), low B lymphocytes (CD19+ cells), and increased CD4/CD8 ratio in neonates and (2) low T lymphocytes (CD3+, CD4+, CD8+ cells) with high natural killer cells (CD16+) and B lymphocytes (CD19+ cells) in other groups. Low preoperative total lymphocyte counts were associated with longer intensive care unit stay in patients after bidirectional Glenn and Fontan procedure ( P = .03 and P = .01, respectively) and low leukocyte counts with higher incidence of pleural effusions and chylothorax after Fontan procedure ( P = .005 and P = .002, respectively). CONCLUSIONS: Single ventricle patients display several immunological abnormalities. Beyond the neonatal age, an immune pattern includes CD3+, CD4+, CD8+ lymphopenia, and CD16+ and CD19+ lymphocytosis. B-cell lymphocytosis compensates T-cell lymphopenia, producing normal total lymphocyte counts in patients early after Fontan surgery. Low preoperative total lymphocyte counts may be associated with longer postoperative intensive care unit stay in patients with bidirectional Glenn and Fontan procedure and leukopenia with pleural effusions in Fontan patients.

AB - We reflect upon highlights of a facilitated panel discussion from the 2016 Pediatric Cardiac Intensive Care Society Meeting. The session was designed to explore challenges, share practical clinical experiences, and review ethical underpinnings surrounding decisions to offer intensive, invasive therapies to patients who have a poor prognosis for survival or are likely to be burdened with multiple residual comorbidities if survival is achieved. The discussion panel was representative of a variety of disciplines including pediatric cardiology, cardiac intensive care, nursing, and cardiovascular surgery as well as different health-care delivery systems. Key issues discussed included patient's best interests, physician obligations, moral distress, and communication in the context of decisions about providing therapy for patients with a poor prognosis.

AB - Scimitar syndrome repair represents a challenge due to the high incidence of postoperative pulmonary venous obstruction associated with classic surgical strategies. In situ pericardial rerouting technique has been considered a promising alternative approach due to its simplicity and excellent midterm results. Access to the left atrium can be difficult in young patients with severe dextrocardia and hypoplastic right lung. We describe a modification of the original rerouting technique in which the atrial septum is repositioned in order to create a wide opening in the lateral aspect of the left atrium and ensure an adequate size of the reconstructed pathway. PMID- 29187110 TI - Experience with an Acuity Adaptable Care Model for Pediatric Cardiac Surgery. AB - BACKGROUND: We describe the implementation of and outcomes associated with an acuity adaptable care model for pediatric patients undergoing cardiac surgery. METHODS: Consecutive patients undergoing an index cardiac operation between July 2007 and June 2015 were included. From July 2007 through June 2010, a conventional model existed in which patients moved among units and care teams based on age, severity of illness, and operative status (conventional group). A transitional period existed between July 2010 and June 8, 2012 (transitional group). From June 9, 2012, through June 2015, an acuity adaptable model was used in which patients remained in the cardiac care unit and received care from the same clinical team throughout their hospitalization (acuity adaptable group). RESULTS: Included were 2,363 patients: 925 in the conventional group, 520 in the transitional group, and 918 in the acuity adaptable group. In relation to the conventional group, the adjusted odds of operative mortality in the acuity adaptable group was 0.55 (95% confidence interval: 0.26-1.18; P = .12). The failure to rescue rate (ie, number of deaths in patients with any complication divided by the number of total patients with any complication) decreased (conventional group, 8.7%; acuity adaptable group, 4.2%; P = .04). In relation to the conventional group, postoperative hospital length of stay tended to be shorter in the acuity adaptable group ( P = .07). CONCLUSIONS: The implementation of an acuity adaptable care model was feasible in our pediatric cardiac program. The favorable associations identified between the new model and outcomes are promising but warrant confirmation in a larger, multicenter study.

PMID- 29187112 TI - The Impact of Time to Rate Control of Junctional Ectopic Tachycardia After Congenital Heart Surgery. AB - BACKGROUND: Junctional ectopic tachycardia (JET) after congenital heart disease (CHD) surgery is often self-limiting but is associated with increased risk of morbidity and mortality. Contributing factors and impact of time to achieve rate control of JET are poorly described. METHODS: From January 2010 to June 2015, a retrospective, single-center cohort study was performed of children who developed JET after CHD surgery . We classified the cohort into two groups: patients who achieved rate control of JET in <=24 hours and in >24 hours. We examined factors associated with time to rate control and compared clinical outcomes (mortality, duration of mechanical ventilation, length of intensive care unit [ICU], and hospital stay) between the two groups. RESULTS: Our cohort included 27 children, with a median age of 3 (interquartile range: 0.7-38] months. The most common CHD lesions were ventricular septal defect (n = 10, 37%), tetralogy of Fallot (n = 7, 25.9%), and transposition of the great arteries (n = 4, 14.8%). In all, 15 (55.6%) and 12 (44.4%) patients achieved rate control of JET in <=24 hours and >24 hours, respectively. There was a difference in median mechanical ventilation time (97 [21-145) vs 311 [100-676] hours; P = .013) and ICU stay (5.0 [2.0-8.0] vs 15.5 [5.5-32.8] days, P = .023) between the patients who achieved faster rate control than those who didn't. There was no difference in length of hospital stay and mortality between the groups. CONCLUSION: Our study demonstrated that time to achieve rate control of JET was associated with increased duration of mechanical ventilation and ICU stay.

Both two- and three-dimensional echocardiography (3DE) can provide detailed information about the mechanism(s) of valve failure and insights into valve adaptation during follow-up. We report two patients who underwent tricuspid valve repair using Gore Tex neochordae, repairs which were facilitated by and assessed with 3DE. Both infants had less than mild residual TR and no valve tethering at hospital discharge. Furthermore, follow-up 3DEs have helped to confirm valve competence, lack of tethering, and growth of the valve and valve apparatus. PMID- 29187117 TI - Practical Considerations in Donation After Circulatory Determination of Death in Switzerland. AB - Faced with similar issues of organ scarcity to its neighbors, Switzerland has developed donation after circulatory determination of death (DCDD) as a way to expand the organ pool since 1985. Here, we analyze the history, practical considerations, and ethical issues relating to the Swiss donation after circulatory death programs. In Switzerland, determination of death for DCDD requires a stand-off period of 10 minutes. This time between cardiac arrest and the declaration of death is mandated in the guidelines of the Swiss Academy of Medical Sciences. As in other DCDD programs, safeguards are put to avoid physicians denying lifesaving treatment to savable patients because of being influenced by receivers' interest. An additional recommendation could be made: Recipients should be transparently informed of the worse graft outcomes with DCDD programs and given the possibility to refuse such organs. PMID- 29187118 TI - Multifocal human papillomavirus detection in palatine and pharyngeal tonsils. AB - BACKGROUND: Multifocal human papillomavirus (HPV) infection into the palatine and pharyngeal tonsils, which might be linked to a second primary tumor of HPV positive oropharyngeal cancer (OPC), was investigated. PATIENTS AND METHODS: One hundred and five patients with various head and neck diseases including 14 patients with OPC were enrolled in this study. Swabs from the palatine and pharyngeal tonsils were collected in each individual, and auto-nested GP5+/GP6+ PCR for HPV DNA was performed. RESULTS: HPV DNA was detected in the palatine tonsil or the pharyngeal tonsil in a small subset of upper respiratory tract cancer other than OPC (URTC) and non-cancer diseases. Furthermore, HPV DNA was detected in both the palatine and pharyngeal tonsils in the same individual in 2 of 48 (4%) URTC cases, and 1 of 43 (2%) non-cancer cases. On the other hand, p16 positive OPC cases demonstrated a higher HPV DNA detection rate (4 of 9, 44.4%) compared with other disease groups. CONCLUSION: HPV DNA detection in both the palatine and pharyngeal tonsils in the same individual, especially in HPV-OPC, suggested the ability of HPV to infect tonsillar tissues of Waldeyer's ring multifocally. PMID- 29187119 TI - Photocatalytic degradation of diclofenac using TiO2-SnO2 mixed oxide catalysts. AB - The complex nature of diclofenac limits its biological degradation, posing a serious threat to aquatic organisms. Our present work aims to eliminate diclofenac from wastewater through photocatalytic degradation using TiO2-SnO2 mixed-oxide catalysts under various operating conditions such as catalyst loading, initial diclofenac concentration and initial pH. Different molar ratios of Ti-Sn (1:1, 5:1, 10:1, 20:1 and 30:1) were prepared by the hydrothermal method and were characterized. The results indicated that addition of Sn in small quantity enhances the catalytic activity of TiO2. Energy Band gap of the TiO2 SnO2 catalysts was found to increase with an increase in Tin content. TiO2-SnO2 catalyst with a molar ratio of 20:1 was found to be the most effective when compared to other catalysts. The results suggested that initial drug concentration of 20 mg/L, catalyst loading of 0.8 g/L and pH 5 were the optimum operating conditions for complete degradation of diclofenac. Also, the TiO2-SnO2 catalyst was effective in complete mineralization of diclofenac with a maximum total organic carbon removal of 90% achieved under ultraviolet irradiation. The repeatability and stability results showed that the TiO2-SnO2 catalyst exhibited an excellent repeatability and better stability over the repeated reaction cycles. The photocatalytic degradation of diclofenac resulted in several photoproducts, which were identified through LC-MS. PMID- 29187120 TI - Growth and Neurodevelopmental Outcomes of Early, High-Dose Parenteral Amino Acid Intake in Very Low Birth Weight Infants: A Randomized Controlled Trial. AB - BACKGROUND: Administration of high-dose parenteral amino acids (AAs) to premature infants within hours of delivery is currently recommended. This study compared the effect of lower and higher AA administration starting close to birth on short term growth and neurodevelopmental outcomes at 18-24 months corrected gestational age (CGA). METHODS: Infants <1250 g birth weight (n = 168) were randomly assigned in a blinded fashion to receive parenteral nutrition providing 1-2 g/kg/d AA and advancing daily by 0.5 g/kg/d to a goal of 4 g/kg/d (standard AA) or 3-4 g/kg/d and advancing to 4 g/kg/d by day 1. The primary outcome was neurodevelopmental outcomes measured by the Bayley Scales of Infant and Toddler Development, Third Edition at 18-24 months CGA. Secondary outcomes were growth parameters at 36 weeks CGA among infants surviving to hospital discharge, serum bicarbonate, serum urea nitrogen, creatinine, AA profiles in the first week of life, and incidence of major morbidities and mortality. RESULTS: No differences in neurodevelopmental outcome were detected between the high and low AA groups. Infants in the high AA group had significantly lower mean weight, length, and head circumference percentiles than those in the standard AA group at 36 weeks CGA and at hospital discharge. These differences did not persist after controlling for birth growth parameters, except for head circumference. Infants in the high AA group had higher mean serum urea nitrogen than the standard group on each day throughout the first week. CONCLUSION: Current recommendations for high-dose AA starting at birth are not associated with improved growth or neurodevelopmental outcomes.

PMID- 29187122 TI - Social determinants of cancer incidence and mortality around the world: an ecological study. AB - Cancer continues to be a leading cause of mortality and morbidity the world over. While the incidence of cancer is projected to increase by 70% over the next two decades, some research findings suggest a disproportionate distribution of new cancer cases and attendant fatalities across certain regions of the world, with poor and lower income countries worse affected at a time when advances in cancer research, medical technology, and drug development are giving rise to better cancer survival in developed countries. In this study, the role of selected social determinants of health in gauging cancer outcomes relative to incidence across various countries in different regions of the world was explored. The results indicated that the education index, income index, Gini coefficient, availability of cancer control policies and programs, as well as health system performance have an association with and are good predictors of the mortality to incidence ratio (MIR) of lung, breast, cervical, and colorectal cancers. In other words, populations with better education, higher incomes and lower inequalities, active cancer control policies and programs and high performing health systems have better cancer outcomes as reflected in lower MIRs relative to other populations. PMID- 29187123 TI - A qualitative investigation of the nature of "informal supervision" among therapists in training. AB - OBJECTIVE: This study investigated how, when, why, and with whom therapists in training utilize "informal supervision"-that is, engage individuals who are not their formally assigned supervisors in significant conversations about their clinical work. METHOD: Participants were 16 doctoral trainees in clinical and counseling psychology programs. Semi-structured interviews were conducted and analyzed using the Consensual Qualitative Research (CQR) method. RESULTS: Seven domains emerged from the analysis, indicating that, in general, participants believe that informal and formal supervision offer many of the same benefits, including validation, support, and reassurance; freedom and safety to discuss doubts, anxieties, strong personal reactions to patients, clinical mistakes and challenges; and alternative approaches to clinical interventions. However, several differences also emerged between these modes of learning-for example, formal supervision is seen as more focused on didactics per se ("what to do"), whereas informal supervision is seen as providing more of a "holding environment." CONCLUSIONS: Overall, the findings of this study suggest that informal supervision is an important and valuable adjunctive practice by which clinical trainees augment their professional competencies. Recommendations are proposed for clinical practice and training, including the need to further specify the ethical boundaries of this unique and essentially unregulated type of supervision. PMID- 29187124 TI - Factors affecting unsafe behavior in construction projects: development and validation of a new questionnaire. AB - INTRODUCTION: Occupational safety in general, and construction safety in particular, is a complex phenomenon. This study was designed to develop a new valid measure to evaluate factors affecting unsafe behavior in the construction industry. METHODS: A new questionnaire was generated from qualitative research according to the principles of grounded theory. Key measurement properties (face validity, content validity, construct validity, reliability and discriminative validity) were examined using qualitative and quantitative approaches. The receiver operating characteristic curve was used to estimate the discriminating power and the optimal cutoff score. RESULTS: Construct validity revealed an interpretable 12-factor structure which explained 61.87% of variance. Good internal consistency (Cronbach's alpha = 0.94) and stability (intra-class correlation coefficient = 0.93) were found for the new instrument. The area under the curve, sensitivity and specificity were 0.80, 0.80 and 0.75, respectively. The new instrument also discriminated safety performance among the construction sites with different workers' accident histories (F = 6.40, p < 0.05). CONCLUSION: The new instrument appears to be a valid, reliable and sensitive instrument that will contribute to investigating the root causes of workers' unsafe behaviors, thus promoting safety performance in the construction industry. PMID- 29187126 TI - Simulation-Based Communication Skills Training for Experienced Clinicians to Improve Family Conversations About Organ and Tissue Donation. AB - INTRODUCTION: The approach, communication skills, and confidence of clinicians responsible for raising deceased organ donation may influence families' donation decisions. The aim of this study was to increase the preparedness and confidence of intensive care clinicians allocated to work in a "designated requester" role. DESIGN: We conducted a posttest evaluation of an innovative simulation-based training program. Simulation-based training enabled clinicians to rehearse the "balanced approach" to family donation conversations (FDCs) in the designated requester role. Professional actors played family members in simulated clinical settings using authentic scenarios, with video-assisted reflective debriefing. Participants completed an evaluation after the workshop. Simple descriptive statistical analysis and content analysis were performed. RESULTS: Between January 2013 and July 2015, 25 workshops were undertaken with 86 participants; 82 (95.3%) returned evaluations. Respondents were registered practicing clinicians; over half (44/82; 53.7%) were intensivists. Most attended a single workshop. Evaluations were overwhelmingly positive with the majority rating workshops as outstanding (64/80; 80%). Scenario fidelity, competence of the actors, opportunity to practice and receive feedback on performance, and feedback from actors, both in and out of character, were particularly valued. Most (76/78; 97.4%) reported feeling more confident about their designated requester role. DISCUSSION: Simulation-based communication training for the designated requester role in FDCs increased the knowledge and confidence of clinicians to raise the topic of donation. PMID- 29187125 TI - Nitro-Oleic Acid (NO2-OA) Release Enhances Regional Angiogenesis in a Rat Abdominal Wall Defect Model. AB - Ventral hernia is often addressed surgically by the placement of prosthetic materials, either synthetic or from allogeneic and xenogeneic biologic sources. Despite advances in surgical approaches and device design, a number of postsurgical limitations remain, including hernia recurrence, mesh encapsulation, and reduced vascularity of the implanted volume. The in situ controlled release of angiogenic factors from a scaffold facilitating abdominal wall repair might address some of these issues associated with suboptimal tissue reconstruction. Furthermore, a biocomposite material that combines the favorable mechanical properties achievable with synthetic materials and the bioactivity associated with xenogeneic tissue sources would be desirable. In this report, an abdominal wall repair scaffold has been designed based on a microfibrous, elastomeric poly(ester carbonate)urethane urea matrix integrated with a hydrogel derived from decellularized porcine dermis (extracellular matrix [ECM] gel) and poly(lactic-co glycolic acid) (PLGA) microspheres loaded with nitro-oleic acid (NO2-OA). NO2-OA is an electrophilic fatty acid nitro-alkene derivative that, under hypoxic conditions, induces angiogenesis. This scaffold was utilized to repair a rat abdominal wall partial thickness defect, hypothesizing that the nitro-fatty acid release would facilitate increased angiogenesis at the 8-week endpoint. The quantification of neovascularization was conducted by novel methodologies to assess vessel morphology and spatial distribution. The repaired abdominal wall defects were evaluated by histopathologic methods, including quantification of the foreign body response and cellular ingrowth. The results showed that NO2-OA release was associated with significantly improved regional angiogenesis. The combined biohybrid scaffold and NO2-OA-controlled release strategy also reduced scaffold encapsulation, increased wall thickness, and enhanced cellular infiltration. More broadly, the three components of the composite scaffold design (ECM gel, polymeric fibers, and PLGA microparticles) enable the tuning of performance characteristics, including scaffold bioactivity, degradation, mechanics, and drug release profile, all decisive factors to better address current limitations in abdominal wall repair or other soft tissue augmentation procedures. PMID- 29187127 TI - The Discussion of Sexual Dysfunction Before and After Kidney Transplantation From the Perspective of the Renal Transplant Surgeon. AB - INTRODUCTION: Sexual dysfunction (SD) is a common problem in chronic kidney disease (CKD) and endures in 50% of patients after kidney transplantation (KTx), diminishing patients' expectations of life after KTx. Unfortunately, SD is often ignored by renal care providers. Research questions as part of a research project among all renal care providers, transplant surgeons' perspectives were obtained on sexual health care for KTx recipients, including their opinion on who should be accountable for this care. In addition, surgeons' practice and knowledge regarding SD were evaluated. DESIGN: A 39-item questionnaire was sent to all Dutch surgeons and residents specialized in KTx (n = 47). RESULTS: Response was 63.8%. None of the respondents discussed SD with their patients, before or after surgery. Most important barrier was that surgeons do not feel accountable for it (73.9%); 91.7% thought this accountability should lie with the nephrologist. Another barrier was insufficient knowledge (39.1%). In 75% of the respondents, (almost) no knowledge regarding SD was present and 87.5% noticed education on SD was insufficient during residence training. DISCUSSION: Dutch renal transplant surgeons rarely discuss SD with their patients with CKD, as they do not feel accountable for it; this accountability was appointed to the nephrologist. Knowledge and education regarding SD were found insufficient in enabling surgeons and for some it reflects in barriers toward discussing SD. Results emphasize that accountability for providing sexual health care to patients with CKD should lie elsewhere; however, surgeons could briefly provide information on sexual health after KTx, so unfulfilled expectations may be prevented.

AB - For frequently seen noncomplex cancer presentation, it is important to use rapid, effective, and inexpensive radiotherapy methods. However, for the complex cancer, these sophisticated radiotherapy techniques can decrease morbidity and mortality in our transplant patients and should be considered.

PMID- 29187132 TI - Lymphatic Leak After Intestinal Transplantation: Aspects of the Donor Technique. AB - The rich component of lymphatics makes the intestine prone to leaks of lymph after transplantation secondary to their transection during procurement.

PMID- 29187131 TI - Haptoglobin 2-2 Genotype, Patient, and Graft Survival in Renal Transplant Recipients. AB - BACKGROUND: Cardiovascular disease is the leading cause of death in renal transplant recipients. An association between haptoglobin genotype 2-2 and cardiovascular disease has been found in patients with diabetes mellitus and liver transplant recipients. To date, the role of haptoglobin genotype after renal transplantation has not been studied. METHODS: In this single-center retrospective cohort study of 1975 adult Norwegian transplant recipients, who underwent transplantation between 1999 and 2011, we estimated the risk of all cause and cardiovascular mortality and overall and death-censored graft loss for patients with haptoglobin genotype 2-2 compared to genotype 2-1 or 1-1, after adjustment for confounders and competing risks. RESULTS: We found no associations between haptoglobin genotype 2-2 and cardiovascular mortality (subdistributional hazard ratio 1.08, 95% confidence interval 0.78-1.49; P = .63). We also failed to detect any association between haptoglobin 2-2 genotype and all-cause mortality, overall graft loss, and death-censored graft loss. Similar results were found in the subpopulation of transplant recipients with diabetes. CONCLUSION: In this large cohort of kidney transplant recipients, we could not demonstrate any association between haptoglobin 2-2 genotype and patient or graft survival after renal transplantation. PMID- 29187133 TI - Peer Leaders Increase Organ Donor Designation Among Members of Historically African American Fraternities and Sororities. AB - INTRODUCTION: Health education programs can positively impact organ donor designation among African Americans, a disproportionately represented group on the transplant waiting list. Alumni chapters of historically African American sororities and fraternities are a novel setting for organ donation education and research. RESEARCH QUESTIONS: This study tested the effectiveness of a lay health advisor model to increase donor designation registrations on the Michigan Organ Donor Registry among members of Midwest alumni chapters. The secondary outcome was change in attitudes toward donation assessed by pre-post questionnaire. DESIGN: Sorority/fraternity members were trained to deliver educational presentations during a 12-month period. Follow-up messaging consisted of tailored newsletters and e-mails. A cluster randomized design was utilized with 25 chapters (16 sororities and 9 fraternities) assigned to intervention (organ donation) or comparison (chronic disease). RESULTS: Odds of signing up for the donor registry were 1.45 times higher for the intervention group than the comparison group. Among those identified as nondonors at baseline, the odds of signing up were 1.58 times higher for intervention than comparison. DISCUSSION: Using lay health advisors in African American sororities and fraternities can increase enrollment in a donor registry. Alumni chapters offer a unique and viable setting for organ donation education and research; relationship building with chapter officials is key to success. PMID- 29187134 TI - Correlation Between Renal Cortical Stiffness and Histological Determinants by Point Shear-Wave Elastography in Patients With Kidney Transplantation. AB - INTRODUCTION: Renal allograft biopsy is the gold standard for the detection of histological lesions of chronic allograft dysfunction. The identification of a noninvasive routine test would be desirable. Elastosonography is used to assess tissue stiffness according to viscosity, and no data are available on the use of point quantification shear-wave elastography (ElastPQ) for the evaluation of renal chronic lesions. RESEARCH QUESTION: To evaluate the feasibility of ElastPQ to assess cortical allograft stiffness and to determine the correlation of clinical, biological, and pathological factors with the diagnostic accuracy of kidney stiffness values in patients with histological lesions. DESIGN: Forty-two patients underwent kidney transplant biopsy and 10 valid measurements of ElastPQ, blindly performed by 2 operators. The interobserver reproducibility was assessed according to intraclass correlation coefficient. The ElastPQ measurements and the clinical data were compared using the Spearman correlation analysis. RESULTS: 97.6% reliable measurements were obtained using ElastPQ, with an excellent interobserver agreement. The kidney stiffness was significantly higher in the patients with a time since transplantation >12 months and was correlated with chronic lesions (interstitial fibrosis, tubular atrophy transplant glomerulopathy, and mesangial matrix), with the interstitial fibrosis/tubular atrophy, score and with the sum of the scores of the chronic lesions. Mesangial matrix increase is the only independent determinant of kidney stiffness. DISCUSSION: ElastPQ is a noninvasive, reproducible, and sensitive diagnostic tool able to detect moderate/severe chronic lesions. Its routine use during follow-up can identify patients eligible for biopsy, which remains the gold standard exam for detecting chronic allograft dysfunction. PMID- 29187135 TI - A Clustered Randomized Trial of an Educational Intervention During Transplant Evaluation to Increase Knowledge of Living Donor Kidney Transplant. AB - INTRODUCTION: Maximizing education about living donor kidney transplant (LDKT) during the in-person evaluation at the transplant center may increase the numbers of kidney patients pursuing LDKT. Research Questions and Design: To test the effectiveness of a 1-time LDKT educational intervention, we performed a cluster randomized trial among 499 patients who presented for evaluation of kidney transplant. We compared usual care education (n = 250) versus intensive LDKT education (n = 249), which was implemented only on the evaluation day and consisted of viewing a 25-minute video of information and stories about LDKT and discussion of LDKT possibilities with an educator. Our primary outcome was knowledge of LDKT, 1 week after the transplant evaluation. RESULTS: One week after evaluation, patients who received intensive education had higher knowledge than patients who received usual care (12.7 vs. 11.7; P = .0008), but there were no differences in postevaluation readiness for LDKT. Among patients who had not previously identified a potential living donor, receiving intensive education was associated with increased willingness to take steps toward LDKT. DISCUSSION: In conclusion, expansion of LDKT education within the evaluation day may be helpful, but interventions that are implemented at multiple times and for greater duration may be necessary to ensure larger and long-term behavioral changes in pursuit of LDKT. PMID- 29187136 TI - Results of a Patient Survey for Assessment Services in Renal Transplant Patients With a History of Cancer. AB - Patients with cancer who require a kidney transplant often face a prolonged time on the waiting list to ensure a sufficient relapse-free time. Patients and relatives were invited to the patient assessment service where they get an individualized risk assessment and a recommendation for transplantation and waiting period directly from an expert panel. We investigated in 31 patients who filled out questionnaires concerning depression, anxiety, distress, and quality of life and were interviewed for their satisfaction, experiences, and circumstances of the counseling. In 12 (39%) of the 31 patients, a recommendation for transplantation could be made, although the regular waiting period was not yet achieved. The assessment service was received as very good or good by 22 (79%) of 28 patients. We found no relevant differences in patients with regular and shortened waiting time. An interdisciplinary assessment service is a valuable instrument to help with a decision-making between 2 life-threatening conditions. PMID- 29187137 TI - Evaluation of Filgrastim Therapy in Kidney Transplant Recipients. AB - CONTEXT: Neutropenia is associated with a high risk of serious infections in kidney transplant recipients. There are no sufficient studies of using granulocyte colony-stimulating factors, such as filgrastim, in renal transplant recipients to establish a clear, specified role of this off-label indication. Using filgrastim in these patients may increase the risk of rejection by overstimulating the immune system. OBJECTIVE: To evaluate the use of filgrastim in adult kidney transplant recipients presenting with neutropenia. PATIENTS AND DESIGN: Data were obtained from a medication utilization report of filgrastim in kidney transplant recipients at our center from September 2012 to August 2015. Main Outcome Measure(s) and Results: There were 28 cases of neutropenia that were treated with a range of 1 to 5 doses of filgrastim 300 or 480 MUg, with a mean of 1.79 doses. The mean total dose of filgrastim administered per episode of neutropenia was 632 MUg (8.6 MUg/kg). Overall, 87.5% of the cases achieved a white blood cell count of at least 3 * 109 cells/L within 7 days of hospital discharge. There were no cases of infection or acute rejection following treatment. CONCLUSIONS: The use of filgrastim in kidney transplant recipients demonstrated success in reversing neutropenia. Short courses of therapy were required with minimal adverse events. Patients who required readmission were successfully re-treated. Additional studies are required to determine the most effective dose and duration of treatment. PMID- 29187138 TI - Up to a Third of Renal Transplant Recipients Have Deficiencies in Cognitive Functioning. AB - INTRODUCTION: Kidney transplantation is beneficial in improving cognitive abilities in patients with chronic kidney disease; however, there is still uncertainty concerning which cognitive domains benefit and to what extent. AIM: In the present study, cognitive functioning of renal transplant recipients was compared to normative data. Sociodemographic and clinical parameters that were associated with low cognitive performance were identified. DESIGN: A total of 109 renal transplant recipients (63% men) participated in the study, with a mean age of 51.8 (standard deviation [SD] = 14.2) years. The cognitive test battery consisted of measurements assessing memory, attention, executive function, reproductive, and deductive ability. RESULTS: In all tests, participants showed mean scores ranging within 1 SD of the population means. However, except for tests measuring memory, the percentage of participants scoring more than 1 SD below normed means was higher than expected in a normal distribution of performance. In certain tests, up to a third of the participants scored below average. Participants with continuous low performance (11%) showed higher age, poorer education, a longer time since transplantation, higher serum levels of urea and creatinine, and were more likely to have a deceased donor allograft. DISCUSSION: Altough cognitive performance in renal transplant recipients matches normative data and confirms former findings, the amount of patients scoring more than 1 SD below average suggests that there are a considerable number of patients whose cognitive performance in certain domains lies below those of the general population. The identified sociodemographic and biochemical factors might be helpful to identify renal transplant recipients at risk. PMID- 29187139 TI - PON-SC - program for identifying steric clashes caused by amino acid substitutions. AB - BACKGROUND: Amino acid substitutions due to DNA nucleotide replacements are frequently disease-causing because of affecting functionally important sites. If the substituting amino acid does not fit into the protein, it causes structural alterations that are often harmful. Clashes of amino acids cause local or global structural changes. Testing structural compatibility of variations has been difficult due to the lack of a dedicated method that could handle vast amounts of variation data produced by next generation sequencing technologies. RESULTS: We developed a method, PON-SC, for detecting protein structural clashes due to amino acid substitutions. The method utilizes side chain rotamer library and tests whether any of the common rotamers can be fitted into the protein structure. The tool was tested both with variants that cause and do not cause clashes and found to have accuracy of 0.71 over five test datasets. CONCLUSIONS: We developed a fast method for residue side chain clash detection. The method provides in addition to the prediction also visualization of the variant in three dimensional structure. PMID- 29187140 TI - Somatic embryogenesis from seeds in a broad range of Vitis vinifera L. varieties: rescue of true-to-type virus-free plants. AB - BACKGROUND: Somatic embryogenesis is the preferred method for cell to plant regeneration in Vitis vinifera L. However, low frequencies of plant embryo conversion are commonly found. In a previous work we obtained from cut-seeds of a grapevine infected with the Grapevine leafroll associated viruses 1 and 3 (GLRaV 1 and GLRaV-3), high rates of direct regeneration, embryo plant conversion and sanitation. The aim of this study is to evaluate the usefulness of this procedure for regeneration of other grapevine varieties which include some infected with one to three common grapevine viruses (GLRaV-3, Grapevine fanleaf virus (GFLV) and Grapevine fleck virus (GFkV)). As grapevine is highly heterozygous, it was necessary to select from among the virus-free plants those that regenerated from mother tissues around the embryo, (true-to-type). RESULTS: Somatic embryogenesis and plant regeneration were achieved in a first experiment, using cut-seeds from the 14 grapevine varieties Airen, Cabernet Franc, Cabernet Sauvignon, Mencia, Merlot, Monastrell, Petit Verdot, Pinot Blanc (infected by GFLV and GFkV), Pinot Gris, Pinot Meunier, Pinot Noir, Syrah, Tempranillo (infected by GFLV), and Verdil. All regenerated plants were confirmed to be free of GFkV whereas at least 68% sanitation was obtained for GFLV. The SSR profiles of the virus-free plants showed, in both varieties, around 10% regeneration from mother tissue (the same genetic make-up as the mother plant). In a second experiment, this procedure was used to sanitize the varieties Cabernet Franc, Godello, Merlot and Valenci Blanc infected by GLRaV-3, GFkV and/or GFLV. CONCLUSIONS: Cut-seeds can be used as explants for embryogenesis induction and plant conversion in a broad range of grapevine varieties. The high regeneration rates obtained with this procedure facilitate the posterior selection of true-to-type virus-free plants. A sanitation rate of 100% was obtained for GFkV as this virus is not seed transmitted. However, the presence of GLRaV-3 and GFLV in some of the regenerated plants showed that both viruses are seed-transmitted. The regeneration of true-to type virus-free plants from all infected varieties indicates that this methodology may represent an alternative procedure for virus cleaning in grapevine. PMID- 29187141 TI - Experiences and needs of carers of Aboriginal children with a disability: a qualitative study. AB - BACKGROUND: Australian parents/carers of a person with a disability experience higher rates of depression, more financial stress, and are twice as likely to be in poor physical health than the general population. Aboriginal and Torres Strait Islander peoples experience worse health, social and economic outcomes than other Australians, and those with a disability face 'double disadvantage'. This study aimed to better understand the experiences and needs of parents/carers/families of Aboriginal children with a disability. METHODS: Semi-structured in-depth interviews were conducted with parents or primary carers of Aboriginal children aged zero-eight with disability. Interviews were analysed using thematic analysis. RESULTS: Nineteen women (sixteen mothers and three grandmothers) were interviewed. More than half were lone carers (without a partner or spouse). Participants described their experiences, including challenges and facilitators, to providing and accessing care, impacts on their health and wellbeing, and associated economic and non-economic costs of caregiving. Financial strain and social isolation was particularly prominent for lone carers. CONCLUSIONS: Tailoring services to the needs of carers of Aboriginal children with a disability means supporting kinship caregiving, facilitating engagement with other Aboriginal families, and streamlining services and systems to mitigate costs. The experiences described by our participants depict an intersection of race, socio-economic status, gender, disability, and caregiving. Services and funding initiatives should incorporate such intersecting determinants in planning and delivery of holistic care. PMID- 29187142 TI - Gut microbiota-mediated generation of saturated fatty acids elicits inflammation in the liver in murine high-fat diet-induced steatohepatitis. AB - BACKGROUND: The gut microbiota plays crucial roles in the development of non alcoholic steatohepatitis (NASH). However, the precise mechanisms by which alterations of the gut microbiota and its metabolism contributing to the pathogenesis of NASH are not yet fully elucidated. METHODS: Mice were fed with a recently reported new class of high-fat diet (HFD), steatohepatitis-inducing HFD (STHD)-01 for 9 weeks. The composition of the gut microbiota was analyzed by T RFLP. Luminal metabolome was analyzed using capillary electrophoresis and liquid chromatography time-of-flight mass spectrometry (CE- and LC-TOFMS). RESULTS: Mice fed the STHD-01 developed NASH-like pathology within a short period. Treatment with antibiotics prevented the development of NASH by STHD-01. The composition of the gut microbiota and its metabolic activities were markedly perturbed in the STHD-01-fed mice, and antibiotic administration normalized these changes. We identified that long-chain saturated fatty acid and n-6 fatty acid metabolic pathways were significantly altered by STHD-01. Of note, the changes in gut lipidome caused by STHD-01 were mediated by gut microbiota, as the depletion of the gut microbiota could reverse the perturbation of these metabolic pathways. A saturated long-chain fatty acid, palmitic acid, which accumulated in the STHD-01 group, activated liver macrophages and promoted TNF-alpha expression. CONCLUSIONS: Lipid metabolism by the gut microbiota, particularly the saturation of fatty acids, affects fat accumulation in the liver and subsequent liver inflammation in NASH. PMID- 29187143 TI - DMRfinder: efficiently identifying differentially methylated regions from MethylC seq data. AB - BACKGROUND: DNA methylation is an epigenetic modification that is studied at a single-base resolution with bisulfite treatment followed by high-throughput sequencing. After alignment of the sequence reads to a reference genome, methylation counts are analyzed to determine genomic regions that are differentially methylated between two or more biological conditions. Even though a variety of software packages is available for different aspects of the bioinformatics analysis, they often produce results that are biased or require excessive computational requirements. RESULTS: DMRfinder is a novel computational pipeline that identifies differentially methylated regions efficiently. Following alignment, DMRfinder extracts methylation counts and performs a modified single linkage clustering of methylation sites into genomic regions. It then compares methylation levels using beta-binomial hierarchical modeling and Wald tests. Among its innovative attributes are the analyses of novel methylation sites and methylation linkage, as well as the simultaneous statistical analysis of multiple sample groups. To demonstrate its efficiency, DMRfinder is benchmarked against other computational approaches using a large published dataset. Contrasting two replicates of the same sample yielded minimal genomic regions with DMRfinder, whereas two alternative software packages reported a substantial number of false positives. Further analyses of biological samples revealed fundamental differences between DMRfinder and another software package, despite the fact that they utilize the same underlying statistical basis. For each step, DMRfinder completed the analysis in a fraction of the time required by other software. CONCLUSIONS: Among the computational approaches for identifying differentially methylated regions from high-throughput bisulfite sequencing datasets, DMRfinder is the first that integrates all the post-alignment steps in a single package. Compared to other software, DMRfinder is extremely efficient and unbiased in this process. DMRfinder is free and open-source software, available on GitHub ( github.com/jsh58/DMRfinder ); it is written in Python and R, and is supported on Linux. PMID- 29187144 TI - Non-alcoholic fatty liver disease and its associations among adolescents in an urban, Sri Lankan community. AB - BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a common problem across the world. We aimed to determine the prevalence of NAFLD and its associations in Sri Lankan adolescents living in an urban Sri Lankan community. METHOD: The study population consisted of the birth cohort of the year 2000, residing in the Ragama Medical Officer of Health area. Socio-demographic and anthropometric data [anthropometric measurements, blood pressure and total body fat distribution] of these adolescents were collected by trained data collectors. Fasting blood sugar, serum insulin, fasting serum lipids and serum alanine aminotransferase (ALT) levels were measured and an abdominal ultrasound was performed. NAFLD was diagnosed on established ultrasound criteria for fatty liver and absent alcohol consumption. RESULTS: The study sample consisted of 499 adolescents [263 (51.8%) girls]. Forty two (8.4%) had NAFLD. NAFLD was significantly associated with being breast fed for less than 4 months (33.3% vs. 17.1 in controls, p = 0.02), higher waist circumference (prevalence risk ratio 83.3/20.3, 4.1, p < 0.0001), higher body mass index (prevalence risk ratio 40.5/4.8, 8.4, p < 0/0001),higher HOMA-IR (3.7 vs. 1.9, p < 0.0001) and high triglycerides (prevalence risk ratio 14.3/5.8, 2.5, p = 0.033). Adolescents with NAFLD also had a higher amount of total body fat (p < 0.001) and subcutaneous fat (p < 0.001) than those without NAFLD. The number of children with metabolic derangements was higher among adolescents with NAFLD than those without (85.8 vs 26.3 in controls, p < 0.0001), but a family history of hypertension, diabetes, myocardial infarction or dyslipidaemia were not. CONCLUSION: Prevalence of NAFLD was high in Sri Lankan adolescents, and was associated with metabolic derangements, especially obesity, insulin resistance and early cessation of breast feeding. PMID- 29187145 TI - 'Sussing that doctor out.' Experiences and perspectives of people affected by hepatitis C regarding engagement with private general practitioners in South Australia: a qualitative study. AB - BACKGROUND: Australians with chronic hepatitis C (HCV) can access affordable Direct Acting Antiviral (DAA) treatments with high cure rates (>90%), via General Practitioners (GPs). Benefits from this treatment will be maximised if people with HCV readily disclose and engage with private GPs regarding HCV-related issues. Investigating the perceptions and experiences of people affected by HCV with GPs can allow for this pathway to care for HCV to be improved. METHODS: In 2013-2014, 22 purposively sampled participants from South Australia (SA) were interviewed. They a) had contracted or were at risk of hepatitis C (n = 10), b) were key workers who had clients affected by HCV (n = 6), and c) met both a) and b) criteria (n = 6). The semi-structured interviews were recorded, transcribed and thematically analysed. RESULTS: People affected by HCV viewed GPs as a source of general healthcare but, due to negative experiences and perceptions, many developed a strategy of "sussing" out doctors before engaging with and disclosing to a GP regarding HCV-related issues. Participants were doubtful about the benefits of engagement and disclosure, and did not assume that they would be provided best-practice care in a non-discriminatory, non-judgemental way. They perceived risks to confidentiality and risks of changes to the care they received from GPs upon disclosure. CONCLUSION: GPs may need to act in ways that counteract the perceived risks and persuade people affected by HCV of the benefits of seeking HCV-related care. PMID- 29187146 TI - Determination of antimicrobial susceptibility patterns in Staphylococcus aureus strains recovered from patients at two main health facilities in Kabul, Afghanistan. AB - BACKGROUND: Staphylococcus aureus (S. aureus) is a major pathogen implicated in skin and soft tissue infections, abscess in deep organs, toxin mediated diseases, respiratory tract infections, urinary tract infections, post-surgical wound infections, meningitis and many other diseases. Irresponsible and over use of antibiotics has led to an increased presence of multidrug resistant organisms and especially methicillin resistant Staphylococcus aureus (MRSA) as a major public health concern in Afghanistan. As a result, there are many infections with many of them undiagnosed or improperly diagnosed. We aimed to establish a baseline of knowledge regarding the prevalence of MRSA in Kabul, Afghanistan, as well as S. aureus antimicrobial susceptibility to current available antimicrobials, while also determining those most effective to treat S. aureus infections. METHODS: Samples were collected from patients at two main Health facilities in Kabul between September 2016 and February 2017. Antibiotic susceptibility profiles were determined by the disc diffusion method and studied using standard CLSI protocols. RESULTS: Out of 105 strains of S. aureus isolated from pus, urine, tracheal secretions, and blood, almost half (46; 43.8%) were methicillin sensitive Staphylococcus aureus (MSSA) while 59 (56.2%) were Methicillin resistant Staphylococcus aureus (MRSA). All strains were susceptible to vancomycin. In total, 100 (95.2%) strains were susceptible to rifampicin, 96 (91.4%) susceptible to clindamycin, 94 (89.5%) susceptible to imipenem, 83 (79.0%) susceptible to gentamicin, 81(77.1%) susceptible to doxycycline, 77 (77.1%) susceptible to amoxicillin + clavulanic acid, 78 (74.3%) susceptible to cefazolin, 71 (67.6%) susceptible to tobramycin, 68 (64.8%) susceptible to chloramphenicol, 60 (57.1%) were susceptible to trimethoprim-sulfamethoxazole, 47 (44.8%) susceptible to ciprofloxacin, 38 (36.2%) susceptible to azithromycin and erythromycin, 37 (35.2%) susceptible to ceftriaxone and 11 (10.5%) were susceptible to cefixim. Almost all (104; 99.05%) were resistant to penicillin G and only 1 (0.95%) was intermediate to penicillin G. Interestingly, 74.6% of MRSA strains were azithromycin resistant with 8.5% of them clindamycin resistant. Ninety-six (91.4%) of the isolates were multi-drug resistant. CONCLUSIONS: There was a high rate of Methicillin resistance (56.2%) among S. aureus strains in the samples collected and most (91.4%) were multidrug resistant. The most effective antibiotics to treat Staph infections were vancomycin, rifampicin, imipenem, clindamycin, amoxicillin-clavulanic acid, cefazolin, gentamicin and doxycycline. The least effective were azithromycin, ceftriaxone, cefixim and penicillin. We recommend that, where possible, in every case of S. aureus infection in Kabul, Afghanistan, Antibiotic susceptibility testing (AST) should be performed and responsible use of antibiotics should be considered. PMID- 29187147 TI - Genome-wide analysis of miRNAs in Carya cathayensis. AB - BACKGROUND: MicroRNA (miRNA) plays an important role in plant development regulation. Hickory is an economically important plant in which the amount of flowering determines its production. RESULTS: Here, 51 conserved miRNAs, which belong to 16 families and 195 novel miRNAs were identified in hickory genome. For each conserved miRNA family, we used sequences from hickory and other plants to construct a phylogenetic tree, which shows that each family has members in hickory. Some of the conserved miRNA families (i.e., miR167 and miR397) have more members in hickory than in other plants because of gene expansion. MiR166 exhibited tandem duplication with three copies being observed. Many members of these conserved miRNA families were detected in hickory flowers, and the expression patterns of target genes were opposite to those of the related miRNAs, indicating that miRNAs may have important functions in floral regulation of hickory. CONCLUSIONS: Taken together, a comprehensive analysis was conducted to identify miRNAs produced in hickory flower organs, demonstrating functional conservation and diversity of miRNA families among hickory, Arabidopsis, grape, and poplar. PMID- 29187149 TI - DBNorm: normalizing high-density oligonucleotide microarray data based on distributions. AB - BACKGROUND: Data from patients with rare diseases is often produced using different platforms and probe sets because patients are widely distributed in space and time. Aggregating such data requires a method of normalization that makes patient records comparable. RESULTS: This paper proposed DBNorm, implemented as an R package, is an algorithm that normalizes arbitrarily distributed data to a common, comparable form. Specifically, DBNorm merges data distributions by fitting functions to each of them, and using the probability of each element drawn from the fitted distribution to merge it into a global distribution. DBNorm contains state-of-the-art fitting functions including Polynomial, Fourier and Gaussian distributions, and also allows users to define their own fitting functions if required. CONCLUSIONS: The performance of DBNorm is compared with z-score, average difference, quantile normalization and ComBat on a set of datasets, including several that are publically available. The performance of these normalization methods are compared using statistics, visualization, and classification when class labels are known based on a number of self-generated and public microarray datasets. The experimental results show that DBNorm achieves better normalization results than conventional methods. Finally, the approach has the potential to be applicable outside bioinformatics analysis. PMID- 29187148 TI - The development of the DISCO-RC for measuring children's discomfort during research procedures. AB - BACKGROUND: There is a need for data on children's self-reported discomfort in clinical research, helping ethics committees to make their evaluation of discomfort described in study protocols evidence-based. Since there is no appropriate instrument to measure children's discomfort during medical research procedures, we aimed to develop a generic, short and child-friendly instrument: the DISCO-RC questionnaire (DISCOmfort in Research with Children). METHODS: This article describes the six steps of the development of the DISCO-RC. First, we updated a literature search on children's self-reported discomfort in clinical research to get insight in what words are used to measure discomfort (step 1). Subsequently, we interviewed 46 children (6-18 years) participating in research to get insight into important forms of discomfort for children (step 2), and asked them about their preferred response option for measuring discomfort (step 3). Next, we consulted nine paediatric research professionals from various backgrounds for input on the content and feasibility of the DISCO-RC (step 4). Based on the previous steps, we developed a draft version of the DISCO-RC, which we discussed with the professionals. The DISCO-RC was then pretested in 25 children to ensure face-validity from the child's perspective and feasibility (step 5). Finally, validity, reliability and internal consistency were tested (step 6). RESULTS: The search-update revealed several words used for measuring discomfort in research (e.g. 'worries', 'unpleasantness'). The interviews gave insight into important forms of discomfort for children in research (e.g. 'pain', 'boredom'). Children preferred a 5-point Likert scale as response option for the DISCO-RC. The experts recommended a short, digital instrument involving different forms of discomfort, and measuring discomfort of individual research procedures. Pretesting of the DISCO-RC resulted in a few layout changes, and feedback from the children confirmed the feasibility of the DISCO-RC. Convergent validity and test-retest reliability were acceptable. Internal consistency based on item-rest correlations and Cronbach's alpha were low, as expected. CONCLUSIONS: The DISCO RC is a generic, practical and psychometrically sound instrument for measuring children's discomfort during research procedures. It contributes to make the evaluation of discomfort in paediatric research evidence-based. Therefore, we recommend including the DISCO-RC as standard component of paediatric research studies. PMID- 29187150 TI - Identification of pathogens for differential diagnosis of fever with jaundice in the Central African Republic: a retrospective assessment, 2008-2010. AB - BACKGROUND: Febrile jaundice results clinically in generalized yellow coloration of the teguments and mucous membranes due to excess plasma bilirubin, accompanied by fever. Two types are found: conjugated and unconjugated bilirubin jaundice. Jaundice is a sign in several diseases due to viruses (viral hepatitis and arbovirus), parasites (malaria) and bacteria (leptospirosis). In the Central African Republic (CAR), only yellow fever is included on the list of diseases for surveillance. The aim of this study was to identify the other pathogens that can cause febrile jaundice, for better management of patients. METHODS: Between 2008 and 2010, 198 sera negative for yellow fever IgM were randomly selected from 2177 samples collected during yellow fever surveillance. Laboratory analyses targeted four groups of pathogens: hepatitis B, C, delta and E viruses; dengue, chikungunya, Zika, Crimean-Congo haemorrhagic fever, West Nile and Rift Valley arboviruses; malaria parasites; and bacteria (leptospirosis). RESULTS: Overall, 30.9% sera were positive for hepatitis B, 20.2% for hepatitis E, 12.3% for hepatitis C and 8.2% for malaria. The majority of positive sera (40.4%) were from people aged 16-30 years. Co-infection with at least two of these pathogens was also found. CONCLUSION: These findings suggest that a systematic investigation should be undertaken of infectious agents that cause febrile jaundice in the CAR. PMID- 29187151 TI - Pediatric premedication: a double-blind randomized trial of dexmedetomidine or ketamine alone versus a combination of dexmedetomidine and ketamine. AB - BACKGROUND: Preoperative anxiety is common in pediatric patients. When dexmedetomidine is used alone for sedation as premedication, children tend to awaken when separated from their parents, and body movements occur during invasive procedures. We tested the hypothesis that the combination of dexmedetomidine and ketamine may be a useful premedication to alleviate preoperative anxiety and improve cooperation during intravenous cannulation in pediatric patients, while producing minimal adverse events. METHODS: A total of 135 children, aged 2-5 years and American Society of Anesthesiologists status I II, scheduled for eye surgery were randomly allocated to receive intranasal dexmedetomidine 2.5 MUg/kg (group D), oral ketamine 3 mg/kg and intranasal dexmedetomidine 2 MUg/kg (group DK), or oral ketamine 6 mg/kg (group K) 30 min before surgery. Sedation state was evaluated every 10 min after premedication and emotional state was assessed during separation from their parents and peripheral intravenous cannulation. Adverse events were recorded for 24 h postoperatively. The primary endpoint was the rate of successful intravenous cannulation. RESULTS: The rate of successful venous cannulation was 47% with dexmedetomidine alone, 68% with ketamine alone, and 80% with combined premedication (P = 0.006). The rate of satisfactory separation from parents was not different among groups. The incidence of adverse events was higher in group K compared with the other two groups (postoperative vomiting, P = 0.0041; respiratory-related complications during the perioperative period, P = 0.0032; and postoperative psychological/psychiatric adverse events, P = 0.0152). CONCLUSION: The combination of intranasal dexmedetomidine 2 MUg/kg and oral ketamine 3 mg/kg produces satisfactory separation from parents and more successful venous cannulation, allowing children to smoothly accept induction of general anesthesia. TRIAL REGISTRATION: Chinese Clinical Trial Register (Unique identifier: ChiCTR-TRC-14004475 , Date of registration: 2 April 2014). PMID- 29187152 TI - A proximity-based graph clustering method for the identification and application of transcription factor clusters. AB - BACKGROUND: Transcription factors (TFs) form a complex regulatory network within the cell that is crucial to cell functioning and human health. While methods to establish where a TF binds to DNA are well established, these methods provide no information describing how TFs interact with one another when they do bind. TFs tend to bind the genome in clusters, and current methods to identify these clusters are either limited in scope, unable to detect relationships beyond motif similarity, or not applied to TF-TF interactions. METHODS: Here, we present a proximity-based graph clustering approach to identify TF clusters using either ChIP-seq or motif search data. We use TF co-occurrence to construct a filtered, normalized adjacency matrix and use the Markov Clustering Algorithm to partition the graph while maintaining TF-cluster and cluster-cluster interactions. We then apply our graph structure beyond clustering, using it to increase the accuracy of motif-based TFBS searching for an example TF. RESULTS: We show that our method produces small, manageable clusters that encapsulate many known, experimentally validated transcription factor interactions and that our method is capable of capturing interactions that motif similarity methods might miss. Our graph structure is able to significantly increase the accuracy of motif TFBS searching, demonstrating that the TF-TF connections within the graph correlate with biological TF-TF interactions. CONCLUSION: The interactions identified by our method correspond to biological reality and allow for fast exploration of TF clustering and regulatory dynamics. PMID- 29187153 TI - Similar, but different: structurally related azelaic acid and hexanoic acid trigger differential metabolomic and transcriptomic responses in tobacco cells. AB - BACKGROUND: Plants respond to various stress stimuli by activating an enhanced broad-spectrum defensive ability. The development of novel resistance inducers represents an attractive, alternative crop protection strategy. In this regard, hexanoic acid (Hxa, a chemical elicitor) and azelaic acid (Aza, a natural signaling compound) have been proposed as inducers of plant defense, by means of a priming mechanism. Here, we investigated both the mode of action and the complementarity of Aza and Hxa as priming agents in Nicotiana tabacum cells in support of enhanced defense. RESULTS: Metabolomic analyses identified signatory biomarkers involved in the establishment of a pre-conditioned state following Aza and Hxa treatment. Both inducers affected the metabolomes in a similar manner and generated common biomarkers: caffeoylputrescine glycoside, cis-5-caffeoylquinic acid, feruloylglycoside, feruloyl-3-methoxytyramine glycoside and feruloyl-3 methoxytyramine conjugate. Subsequently, quantitative real time-PCR was used to investigate the expression of inducible defense response genes: phenylalanine ammonia lyase, hydroxycinnamoyl CoA quinate transferase and hydroxycinnamoyl transferase to monitor activation of the early phenylpropanoid pathway and chlorogenic acids metabolism, while ethylene response element-binding protein, small sar1 GTPase, heat shock protein 90, RAR1, SGT1, non-expressor of PR genes 1 and thioredoxin were analyzed to report on signal transduction events. Pathogenesis-related protein 1a and defensin were quantified to investigate the activation of defenses regulated by salicylic acid and jasmonic acid respectively. The qPCR results revealed differential expression kinetics and, in general (except for NPR1, Thionin and PR1a), the relative gene expression ratios observed in the Hxa-treated cells were significantly greater than the expression observed in the cells treated with Aza. CONCLUSIONS: The results indicate that Aza and Hxa have a similar priming effect through activation of genes involved in the establishment of systemic acquired resistance, associated with enhanced synthesis of hydroxycinnamic acids and related conjugates. PMID- 29187154 TI - Thymoma with acute gastric volvulus: a case report. AB - BACKGROUND: Acute gastric volvulus (GV) is a rare disease with high mortality rate often associated with anatomic abnormalities. Thymoma is the most common neoplasm located in the anterior mediastinum. There is no reported relationship between thymoma and GV. Here we reported a case of thymoma with initial symptom of acute gastric volvulus. CASE PRESENTATION: A 43-year-old man complained of postprandial abdominal pain, nausea and vomiting. Acute gastric volvulus was diagnosed by chest radiograph, upper digestive tract radiograph and CT scan; later type B3 thymoma was diagnosed by biopsy of mediastinal mass. We inferred that gastric volvulus was secondary to thymoma due to phrenic nerve palsy. The patient was treated with endoscopic de-rotation. Further radiotherapy and chemotherapy were given. During treatments, GV still occurred with less severity and a reduced frequency of approximately every three to four months. CONCLUSION: We report the first case of thymoma initially presented with acute GV. We suspect a pathological mechanism related to the phrenic nerve palsy. This case indicates that thymoma may present alongside rare acute GV. PMID- 29187155 TI - Risk score for first-screening of prevalent undiagnosed chronic kidney disease in Peru: the CRONICAS-CKD risk score. AB - BACKGROUND: Chronic Kidney Disease (CKD) represents a great burden for the patient and the health system, particularly if diagnosed at late stages. Consequently, tools to identify patients at high risk of having CKD are needed, particularly in limited-resources settings where laboratory facilities are scarce. This study aimed to develop a risk score for prevalent undiagnosed CKD using data from four settings in Peru: a complete risk score including all associated risk factors and another excluding laboratory-based variables. METHODS: Cross-sectional study. We used two population-based studies: one for developing and internal validation (CRONICAS), and another (PREVENCION) for external validation. Risk factors included clinical- and laboratory-based variables, among others: sex, age, hypertension and obesity; and lipid profile, anemia and glucose metabolism. The outcome was undiagnosed CKD: eGFR < 60 ml/min/1.73m2. We tested the performance of the risk scores using the area under the receiver operating characteristic (ROC) curve, sensitivity, specificity, positive/negative predictive values and positive/negative likelihood ratios. RESULTS: Participants in both studies averaged 57.7 years old, and over 50% were females. Age, hypertension and anemia were strongly associated with undiagnosed CKD. In the external validation, at a cut-off point of 2, the complete and laboratory-free risk scores performed similarly well with a ROC area of 76.2% and 76.0%, respectively (P = 0.784). The best assessment parameter of these risk scores was their negative predictive value: 99.1% and 99.0% for the complete and laboratory-free, respectively. CONCLUSIONS: The developed risk scores showed a moderate performance as a screening test. People with a score of >= 2 points should undergo further testing to rule out CKD. Using the laboratory-free risk score is a practical approach in developing countries where laboratories are not readily available and undiagnosed CKD has significant morbidity and mortality. PMID- 29187156 TI - Lack of controlled studies investigating the risk of postpartum haemorrhage in cesarean delivery after prior use of oxytocin: a scoping review. AB - BACKGROUND: Postpartum haemorrhage (PPH) is a major cause of maternal mortality and morbidity worldwide. Experimental and clinical studies indicate that prolonged oxytocin exposure in the first or second stage of labour may be associated with impaired uterine contractility and an increased risk of atonic PPH. Therefore, particularly labouring women requiring cesarean delivery constitute a subset of patients that may exhibit an unpredictable response to oxytocin. We mapped the evidence for comparative studies investigating the hypothesis whether the risk for PPH is increased in women requiring cesarean section after induction or augmentation of labour. METHODS: We performed a systematic literature search for clinical trials in Medline, Embase, Web of Science, and the Cochrane Library (May 2016). Additionally we searched for ongoing or unpublished trials in clinicaltrials.gov and the WHO registry platform. We identified a total of 36 controlled trials investigating the exogenous use of oxytocin in cesarean section. Data were extracted for study key characteristics and the current literature literature was described narratively. RESULTS: Our evidence map shows that the majority of studies investigating the outcome PPH focused on prophylactic oxytocin use compared to other uterotonic agents in the third stage of labour. Only 2 dose-response studies investigated the required oxytocin dose to prevent uterine atony after cesarean delivery for labour arrest. These studies support the hypotheses that labouring women exposed to exogenous oxytocin require a higher oxytocin dose after delivery than non labouring women to prevent uterine atony after cesarean section. However, the study findings are flawed by limitations of the study design as well as the outcome selection. No clinical trial was identified that directly compared exogenous oxytocin versus no oxytocin application before intrapartum cesarean delivery. CONCLUSION: Despite some evidence from dose-response studies that the use of oxytocin may increase the risk for PPH in intrapartum cesarean delivery, current research has not investigated the prepartal application of oxytocin in well controlled clinical trials. It was striking that most studies on exogenous oxytocin are focused on PPH prophylaxis in the third stage of labour without differing between the indications of cesarean section and hence the prepartal oxytocin status. PMID- 29187158 TI - Associations of intimate partner violence with postnatal health practices in Bihar, India. AB - BACKGROUND: Reducing neonatal mortality is a global priority, and improvements in postnatal health (PNH) practices in India are needed to do so. Intimate partner violence (IPV) may be associated with PNH practices, but little research has assessed this relationship. METHODS: A cross-sectional analysis of data from a representative household sample of mothers of neonates 0-11 months old in Bihar, India was conducted. The relationship between lifetime IPV experience (physical violence only, sexual violence only, or both physical and sexual violence) and PNH practices [clean cord care, kangaroo mother care, early initiation of breastfeeding (EIBF), delayed bathing, receipt of a postnatal care visit, exclusive breastfeeding, and current post-partum contraceptive use] was assessed using multivariate logistic regression. RESULTS: Over 45% of the 10,469 mothers experienced IPV in their lifetime. The three types of IPV experiences differentially related to PNH practices. Adjusted analyses revealed that compared to those who had never experienced IPV, women who experienced physical violence only (29.0%) had higher odds of skin-to-skin care (AOR = 1.67, 95% CI = 1.42, 1.96) and delayed bathing (AOR = 1.19, 95% CI = 1.03, 1.37), but lower odds of EIBF (AOR = 0.81, 95% CI = 0.70, 0.93) and exclusive breastfeeding (AOR = 0.83, 95% CI = 0.71, 0.96). Mothers who had experienced sexual violence only (2.3%) had lower odds of practicing EIBF (AOR = 0.52, 95% CI = 0.36, 0.76). Those who had both experiences of physical and sexual violence (14.0%) had increased odds of postpartum modern contraceptive use (AOR = 1.35, 95% CI = 1.07, 1.71) and lower odds of delayed bathing (AOR = 0.76, 95% CI = 0.63, 0.91). CONCLUSIONS: The results of this study found differing patterns of vulnerability to poor PNH practices depending on the type of IPV experienced. Efforts to increase access to health services for women experiencing IPV and to integrate IPV intervention into such service may increase PNH practices, and as a result, reduce neonatal mortality. PMID- 29187157 TI - CONSORT to community: translation of an RCT to a large-scale community intervention and learnings from evaluation of the upscaled program. AB - BACKGROUND: Translation encompasses the continuum from clinical efficacy to widespread adoption within the healthcare service and ultimately routine clinical practice. The Parenting, Eating and Activity for Child Health (PEACHTM) program has previously demonstrated clinical effectiveness in the management of child obesity, and has been recently implemented as a large-scale community intervention in Queensland, Australia. This paper aims to describe the translation of the evaluation framework from a randomised controlled trial (RCT) to large-scale community intervention (PEACHTM QLD). Tensions between RCT paradigm and implementation research will be discussed along with lived evaluation challenges, responses to overcome these, and key learnings for future evaluation conducted at scale. METHODS: The translation of evaluation from PEACHTM RCT to the large-scale community intervention PEACHTM QLD is described. While the CONSORT Statement was used to report findings from two previous RCTs, the REAIM framework was more suitable for the evaluation of upscaled delivery of the PEACHTM program. Evaluation of PEACHTM QLD was undertaken during the project delivery period from 2013 to 2016. RESULTS: Experiential learnings from conducting the evaluation of PEACHTM QLD to the described evaluation framework are presented for the purposes of informing the future evaluation of upscaled programs. Evaluation changes in response to real-time changes in the delivery of the PEACHTM QLD Project were necessary at stages during the project term. Key evaluation challenges encountered included the collection of complete evaluation data from a diverse and geographically dispersed workforce and the systematic collection of process evaluation data in real time to support program changes during the project. CONCLUSIONS: Evaluation of large-scale community interventions in the real world is challenging and divergent from RCTs which are rigourously evaluated within a more tightly-controlled clinical research setting. Constructs explored in an RCT are inadequate in describing the enablers and barriers of upscaled community program implementation. Methods for data collection, analysis and reporting also require consideration. We present a number of experiential reflections and suggestions for the successful evaluation of future upscaled community programs which are scarcely reported in the literature. TRIALS REGISTRATION: PEACHTM QLD was retrospectively registered with the Australian New Zealand Clinical Trials Registry on 28 February 2017 (ACTRN12617000315314). PMID- 29187160 TI - Nephrolithiasis and risk of hypertension: a meta-analysis of observational studies. AB - BACKGROUND: Observational studies have demonstrated an association between nephrolithiasis and hypertension. The aim of this meta-analysis was to summarize all available evidence. METHODS: PubMed, EMBASE, the Cochrane Central Register of Controlled Trials databases, and the reference lists of relevant articles were searched to identify observational studies that reported study-specific risk estimates comparing the risk of hypertension in patients with nephrolithiasis. We used a random-effect model to pool the study-specific risk estimates. We also assessed the potential heterogeneity by subgroup analyses, meta-regression analyses, and sensitivity analyses. RESULTS: A total of 7 articles including 9 studies (n = 313,222 participants) were eventually identified in this meta analysis. In comparison with the patients who did not have nephrolithiasis, nephrolithiasis significantly increased the risk of hypertension (OR, 1.43; 95% CI, 1.30-1.56), with significant heterogeneity between these studies (I 2 = 83.5%, P <0.001). The heterogeneity reduced in subgroups of cohort studies, USA, large sample size trials, men, and adjustment for confounding factors >= 5. Sensitivity analysis further demonstrated the results to be robust. CONCLUSIONS: Nephrolithiasis is associated with increased risk of hypertension. Future randomized, high-quality clinical trials are encouraged to definitively clarify the relationship between nephrolithiasis and hypertension, which may influence clinical management and primary prevention of hypertension in nephrolithiasis patients. PMID- 29187159 TI - Decision tree for accurate infection timing in individuals newly diagnosed with HIV-1 infection. AB - BACKGROUND: There is today no gold standard method to accurately define the time passed since infection at HIV diagnosis. Infection timing and incidence measurement is however essential to better monitor the dynamics of local epidemics and the effect of prevention initiatives. METHODS: Three methods for infection timing were evaluated using 237 serial samples from documented seroconversions and 566 cross sectional samples from newly diagnosed patients: identification of antibodies against the HIV p31 protein in INNO-LIA, SediaTM BED CEIA and SediaTM LAg-Avidity EIA. A multi-assay decision tree for infection timing was developed. RESULTS: Clear differences in recency window between BED CEIA, LAg-Avidity EIA and p31 antibody presence were observed with a switch from recent to long term infection a median of 169.5, 108.0 and 64.5 days after collection of the pre-seroconversion sample respectively. BED showed high reliability for identification of long term infections while LAg-Avidity is highly accurate for identification of recent infections. Using BED as initial assay to identify the long term infections and LAg-Avidity as a confirmatory assay for those classified as recent infection by BED, explores the strengths of both while reduces the workload. The short recency window of p31 antibodies allows to discriminate very early from early infections based on this marker. BED recent infection results not confirmed by LAg-Avidity are considered to reflect a period more distant from the infection time. False recency predictions in this group can be minimized by elimination of patients with a CD4 count of less than 100 cells/mm3 or without no p31 antibodies. For 566 cross sectional sample the outcome of the decision tree confirmed the infection timing based on the results of all 3 markers but reduced the overall cost from 13.2 USD to 5.2 USD per sample. CONCLUSIONS: A step-wise multi assay decision tree allows accurate timing of the HIV infection at diagnosis at affordable effort and cost and can be an important new tool in studies analyzing the dynamics of local epidemics or the effects of prevention strategies. PMID- 29187161 TI - Does the oviparity-viviparity transition alter the partitioning of yolk in embryonic snakes? AB - BACKGROUND: The oviparity-viviparity transition is a major evolutionary event, likely altering the reproductive process of the organisms involved. Residual yolk, a portion of yolk remaining unutilized at hatching or birth as parental investment in care, has been investigated in many oviparous amniotes but remained largely unknown in viviparous species. Here, we used data from 20 (12 oviparous and 8 viviparous) species of snakes to see if the oviparity-viviparity transition alters the partitioning of yolk in embryonic snakes. We used ANCOVA to test whether offspring size, mass and components at hatching or birth differed between the sexes in each species. We used both ordinary least squares and phylogenetic generalized least squares regressions to test whether relationships between selected pairs of offspring components were significant. We used phylogenetic ANOVA to test whether offspring components differed between oviparous and viviparous species and, more specifically, the hypothesis that viviparous snakes invest more in the yolk as parental investment in embryogenesis to produce more well developed offspring that are larger in linear size. RESULTS: In none of the 20 species was sex a significant source of variation in any offspring component examined. Newborn viviparous snakes on average contained proportionally more water and, after accounting for body dry mass, had larger carcasses but smaller residual yolks than did newly hatched oviparous snakes. The rates at which carcass dry mass (CDM) and fat body dry mass (FDM) increased with residual yolk dry mass (YDM) did not differ between newborn oviparous and viviparous snakes. Neither CDM nor FDM differed between newborn oviparous and viviparous snakes after accounting for YDM. CONCLUSIONS: Our results are not consistent with the hypothesis that the partitioning of yolk between embryonic and post-embryonic stages differs between snakes that differ in parity mode, but instead show that the partitioning of yolk in embryonic snakes is species-specific or phylogenetically related. We conclude that the oviparity-viviparity transition does not alter yolk partitioning in embryonic snakes. PMID- 29187163 TI - Daptomycin treatment in patients with resistant staphylococcal periprosthetic joint infection. AB - BACKGROUND: Resistant staphylococcal organisms remain a serious problem in the treatment of periprosthetic joint infection (PJI). Higher failure rates have been reported when vancomycin was used. The purpose of this study was to assess the clinical dosage, effect, and safety of daptomycin in patients with resistant staphylococcal PJI. METHODS: We retrospectively enrolled patients with hip or knee PJI who were treated with daptomycin in our institution (n = 16) from January 2013 to December 2014 with a minimum follow-up of 2 years. The patients received daptomycin when glycopeptide could not be used due to multiple resistance, any adverse reaction, chronic kidney disease stage 3 or worse, and previous treatment failure with glycopeptide or empirical therapy. RESULTS: These patients received daptomycin at a median dose of 8.3 mg/kg per day for a median duration of 14 days. The overall treatment success rate was 87.5% (14 of 16 cases) after a median follow-up period of 27 months. In the subgroups of acute and chronic PJI, the success rate was 80% and 91%, respectively. One patient developed asymptomatic transient serum aspartate transaminase (AST) elevation. No severe side effects such as myositis, acute renal failure due to rhabdomyolysis or eosinophilic pneumonia were found in our series. CONCLUSION: Relatively high daptomycin doses combined with adequate surgical intervention were effective in treating resistant staphylococcal PJI. Daptomycin is an option worthy of consideration in PJI patients for whom glycopeptide treatment is unsuitable. Further prospective randomized comparative study is needed in the future. PMID- 29187162 TI - Isolation and characterization of a new naturally immortalized human breast carcinoma cell line, KAIMRC1. AB - BACKGROUND: Breast cancer is one of the most common cancer and a leading cause of death in women. Up to date the most commonly used breast cancer cell lines are originating from Caucasians or Afro-Americans but rarely cells are being derived from other ethnic groups. Here we describe for the first time the establishment of a naturally transformed breast cancer cell line, KAIMRC1 from an Arab woman of age 62 suffering from stage IIB breast cancer (T2N1M0). Moreover, we have characterized these cells for the biological and molecular markers, induction of MAPK pathways as well as its response to different commercially available drugs and compounds. METHODS: Breast cancer tissue sections were minced and cultured in media for several weeks. KAIMRC1 cells were successfully isolated from one of the primary breast tumor tissue cultures without any enzymatic digestion. To study the growth characteristics of the cells, wound healing assay, clonogenic assay, cell proliferation assays and live cell time-lapse microscopy was performed. Karyotyping, Immunophenotyping and molecular pathway specific compound treatment was also performed. A selective breast cancer gene expression panel was used to identify genes involved in the signal transduction dysregulation and malfunction of normal biological processes during breast carcinogenesis. RESULTS: These cells are ER/PR-positive and HER2-negative. The epithelial nature of these cells was confirmed by flow cytometry analysis using epithelial cell markers. They are cuboidal in shape and relatively smaller in size as compared to established cell lines, MCF-7, MDA MB-231 and the normal breast cell line, MCF-10A. In normal cell culture conditions these cells showed the capability of growing both in monolayer as well as in 3-D conformation. They showed a doubling time in vitro of approximately 24 h. They exhibit a modal karyotype of 58-63,X with abnormalities in a couple of chromosomes. KAIMRC1 cells were found to be more responsive to drug treatment in vitro in comparison to the established MDA MB-231 and MCF-7 cell lines. CONCLUSIONS: In conclusion we have isolated and characterized a new naturally immortalized breast cell line, KAIMRC1 with a potential to play a key role in opening up novel avenues towards the understanding of breast carcinoma. PMID- 29187164 TI - Depression stigma and migration - results of a survey from Germany. AB - BACKGROUND: There are barely any studies focusing on migration in relation to mental illness stigma. We explore present attitudes regarding depression among migrants (either born in Germany or born abroad) and non-migrants in Germany, drawing upon three components of public stigma: stereotypes, emotional reactions and desire for social distance. Furthermore, differences in self-stigma of depression between the two groups are analyzed. METHODS: Analyses are based on a representative telephone survey (N = 2013) in Germany. Respondents were presented with a vignette depicting either someone from Turkey or from Germany affected by depression, followed by questions on stereotypes, emotional reactions and desire for social distance. The (anticipated) self-stigma of depression was also assessed. Analyses of variance tested for differences between migrant and non migrant respondents, stratified by migrant status in the vignette. RESULTS: Regarding the depression vignette depicting a non-migrant, there were only few differences between subgroups. However, when presented with a vignette describing someone from Turkey, respondents with migrant background who were foreign-born expressed greater stigmatizing attitudes, e.g. when it comes to stereotypes or desire for social distance. Furthermore, this subsample displayed higher levels of self-stigma of depression, especially regarding the ascription of own responsibility. CONCLUSIONS: The results underline the need to incorporate migration status/ethnicity in stigma research. Differences in attitudes as well as in (anticipated) self-stigma of depression identify foreign-born migrants in Germany as important target groups for tailored anti-stigma interventions, which need to consider diverse cultural backgrounds. PMID- 29187165 TI - ImageJ2: ImageJ for the next generation of scientific image data. AB - BACKGROUND: ImageJ is an image analysis program extensively used in the biological sciences and beyond. Due to its ease of use, recordable macro language, and extensible plug-in architecture, ImageJ enjoys contributions from non-programmers, amateur programmers, and professional developers alike. Enabling such a diversity of contributors has resulted in a large community that spans the biological and physical sciences. However, a rapidly growing user base, diverging plugin suites, and technical limitations have revealed a clear need for a concerted software engineering effort to support emerging imaging paradigms, to ensure the software's ability to handle the requirements of modern science. RESULTS: We rewrote the entire ImageJ codebase, engineering a redesigned plugin mechanism intended to facilitate extensibility at every level, with the goal of creating a more powerful tool that continues to serve the existing community while addressing a wider range of scientific requirements. This next-generation ImageJ, called "ImageJ2" in places where the distinction matters, provides a host of new functionality. It separates concerns, fully decoupling the data model from the user interface. It emphasizes integration with external applications to maximize interoperability. Its robust new plugin framework allows everything from image formats, to scripting languages, to visualization to be extended by the community. The redesigned data model supports arbitrarily large, N-dimensional datasets, which are increasingly common in modern image acquisition. Despite the scope of these changes, backwards compatibility is maintained such that this new functionality can be seamlessly integrated with the classic ImageJ interface, allowing users and developers to migrate to these new methods at their own pace. CONCLUSIONS: Scientific imaging benefits from open-source programs that advance new method development and deployment to a diverse audience. ImageJ has continuously evolved with this idea in mind; however, new and emerging scientific requirements have posed corresponding challenges for ImageJ's development. The described improvements provide a framework engineered for flexibility, intended to support these requirements as well as accommodate future needs. Future efforts will focus on implementing new algorithms in this framework and expanding collaborations with other popular scientific software suites.

AB - BACKGROUND: To summarize the clinical characteristics and potential factors affecting the visual outcomes in patients with cytomegalovirus retinitis following allogeneic haematopoietic stem cell transplantation (HSCT). METHODS: This retrospective study enrolled 12 patients (19 eyes) with cytomegalovirus retinitis after HSCT at Guangzhou First People's Hospital in China between January 2013 and December 2014. Demographic and clinical characteristics, ocular manifestations and visual outcomes were evaluated by reviewing medical records at the Departments of Hematology and Ophthalmology. All patients were followed up at least 6 months after stopping antiviral therapy. The visual outcome was defined as improvement, stabilization and deterioration. RESULTS: The subjects were composed of 7 human leucocyte antigen-matched and 5 mismatched receipts. All patients received combined systemic and intravitreous antiviral therapy. Eleven eyes gained improved or stabilized visual acuity, while 8 eyes suffered deterioration. Eyes with cytomegalovirus load less than 1 * 104 copies/ml in vitreous accounted for higher rate in eyes with good visual prognosis than those with cytomegalovirus copies above 1 * 104 copies/ml (52.63% vs 5.26%, P < 0.001). Human leucocyte antigen-matched receipts gained better visual prognosis than those mismatched ones (47.37% vs10.53%, P < 0.05). The virus types, cytomegalovirus peak in the blood, involved retinal zone and size had no influence on the visual outcomes (all P > 0.05). CONCLUSIONS: High ocular cytomegalovirus copies and mismatched receipts may be potential adverse factors affecting visual outcomes in cytomegalovirus retinitis patients following allogeneic HSCT. PMID- 29187166 TI - What is the safest mode of delivery for extremely preterm cephalic/non-cephalic twin pairs? A systematic review and meta-analyses. AB - BACKGROUND: Given the controversy around mode of delivery, our objective was to assess the evidence regarding the safest mode of delivery for actively resuscitated extremely preterm cephalic/non-cephalic twin pairs before 28 weeks of gestation. METHODS: We searched Cochrane CENTRAL, MEDLINE, EMBASE and http://clinicaltrials.gov from January 1994 to January 2017. Two reviewers independently screened titles, abstracts and full text articles, extracted data and assessed risk of bias. We included randomized controlled trials and observational studies. Our primary outcome was a composite of neonatal death (<28 days of life) and severe brain injury in survivors (intraventricular hemorrhage grade >= 3 or periventricular leukomalacia). We performed random-effects meta analyses, generating odds ratios with 95% confidence intervals for the first and second twin separately, and for both twins together. We assessed the risk of bias using a modified Newcastle Ottawa Scale (NOS) for observational studies and used Grading of Recommendations Assessment, Development and Evaluation approach (GRADE). RESULTS: Our search generated 2695 articles, and after duplicate removal, we screened 2051 titles and abstracts, selecting 113 articles for full text review. We contacted 36 authors, and ultimately, three observational studies met our inclusion criteria. In cephalic/non-cephalic twin pairs delivered by caesarean section compared to vaginal birth at 24+0-27+6 weeks the odds ratio for our composite outcome of neonatal death and severe brain injury for the cephalic first twin was 0.35 (95% CI 0.00-92.61, two studies, I2 = 76%), 1.69 for the non cephalic second twin (95% CI 0.04-72.81, two studies, I2 = 55%) and 0.83 for both twins (95% CI 0.05-13.43, two studies, I2 = 56%). According to the modified Newcastle Ottawa Scale we assessed individual study quality as being at high risk of bias and according to GRADE the overall evidence for our primary outcomes was very low. CONCLUSION: Our systematic review on the safest mode of delivery for extremely preterm cephalic/non-cephalic twin pairs found very limited existing evidence, without significant differences in neonatal death and severe brain injury by mode of delivery. PMID- 29187168 TI - Spasm and flexion-relaxation phenomenon response to large lifting load during the performance of a trunk flexion-extension exercise. AB - BACKGROUND: The flexion relaxation phenomenon (FRP) has been widely investigated. Nevertheless, no study has been reported on the FRP as well as spasm response to large lifting load. The aim of this study was to evaluate the effect of large lifting load on the FRP response and spasm during execution of a flexion extension exercise. METHODS: Twenty-two healthy male university students without low back pain history participated this study. Subjects randomly performed three trials of trunk flexion-extension cycles of 5 s flexion and 5 s extension in each of 4 conditions (three large lifting loads of 15, 20 and 25 kg and one lifting load of 0 kg for comparison). Surface EMG from bilateral erector spinae was recorded during the performance of a trunk anterior flexion-extension exercise. The relaxation phase was determined through the onset of electromyography (EMG) signals. Spasm was evaluated in the relaxation period. The mean normalized electromyography (NEMG) was derived from the raw EMG. RESULTS: Spasm was observed in more than 45% of the individuals and the intensity of muscle activation was increased by more than 78% in the relaxation phase. CONCLUSIONS: A large lifting load could lead to a high prevalence of spasms as well as a high intensity of muscle activations on erector spinae muscle in the relaxation period, which may be associated with the development of low back disorder during the performance of a flexion-extension exercise. PMID- 29187169 TI - The accuracy of the auto-stop function of different endodontic devices in detecting the apical constriction. AB - BACKGROUND: Electronic apex locators (EALs) are modern devices used to determine the working length during root canal preparation. The newest endodontic motors provide an integrated EAL with auto-stop function to prevent instrumentation beyond the predefined working length during rotary root canal preparation. The aim of this study was to compare the accuracy of the auto-stop function of the VDW.Gold RECIPROC motor (VDW, Munich, Germany), the EndoPilot motor (Schlumbohm, Brokstedt, Germany) and the manual measurement with Raypex 6 (VDW, Munich, Germany) to detect the apical constriction (AC). METHODS: Ninety human teeth were chosen and randomly assigned to three experimental groups (30 teeth each): VDW.Gold RECIPROC motor continuous measuring (RCM), EndoPilot continuous measuring (ECM) and Raypex 6 manual measuring (RMM). When the measurement file reached the AC, the file was fixed in the tooth. The tooth was embedded in acrylic resin and the root tip was exposed, so that the histologic structure of the root canal and the file tip was visible for microscopic analysis. Afterwards, the distance of the file tip to the AC (DAC) was automatically computed with a specially developed software tool. RESULTS: The mean DAC were -13.18 MUm (SD 88.46 MUm) for RMM, -22.70 MUm (SD 91.57 MUm) for RCM and 18.74 MUm (SD 88.11 MUm) for ECM. The differences were not statistically significant (P = 0.181). The rates for instrumentation beyond the AC were not statistically different (Chi2 = 4.753, p = 0.096). CONCLUSIONS: All measurement methods showed a high accuracy in detecting the AC. The auto-stop function of these endodontic motors is a reliable addition to the endodontic armamentarium.

AB - After publication of the original article (1) it was noted that the title of this manuscript was incorrect. The title presently reads "The cedar project: using indigenous-specific determinants of health to predict substance use among young pregnant-involved aboriginal women" but should read "The Cedar Project: Using Indigenous-specific determinants of health to predict substance use among young pregnant-involved Indigenous women in Canada". PMID- 29187171 TI - Antibiotic duration and changes in FEV1 are not associated with time until next exacerbation in adult cystic fibrosis: a single center study. AB - BACKGROUND: Pulmonary exacerbations (PEx) are a major driver of morbidity and mortality in cystic fibrosis and reducing their frequency by extending the time between them is an important therapeutic goal. Although treatment decisions for exacerbations are often made based on dynamic changes in lung function, it is not clear if these changes truly impact future exacerbation risk. We analyzed adults with chronic Pseudomonas aeruginosa infection to determine whether changes in FEV1 or duration of intravenous antibiotic therapy were associated with time to the next pulmonary exacerbation. METHODS: Medical records and Cystic Fibrosis Foundation Patient Registry data were examined retrospectively to assess whether various patient-specific demographic factors and exacerbation-specific characteristics were associated with time until next exacerbation using the Andersen-Gill model in order to control for previous exacerbation frequency history. RESULTS: We examined 59 patients with 221 CF pulmonary exacerbations over a 3-year study period. Mean age was 28.2 years and mean baseline FEV1 was 62% predicted. In our univariable model, fall in FEV1 at onset of exacerbation (median absolute -3% predicted change), recovery of FEV1 with treatment (median absolute +3% predicted change) and duration of IV antibiotics (median 16 days) were not associated with time to next exacerbation (median 93.5 days). Paradoxically each one-year increase in age was associated with a reduction in hazard of PEx by 3% (HR 0.97, P = 0.03, 95% CI 0.95-1.00). CONCLUSIONS: FEV1 drop and recovery associated with onset and treatment of a CF pulmonary exacerbation or duration of intravenous antibiotics were not predictive of time until next exacerbation. Our finding that older age may be associated with decreased hazard of exacerbation is likely due to a healthy survivor effect and should be controlled for in clinical trials of pulmonary exacerbations. PMID- 29187172 TI - Investing in the use of a checklist during differential diagnoses consideration: what's the trade-off? AB - BACKGROUND: A key challenge clinicians face when considering differential diagnoses is whether the patient data have been adequately collected. Insufficient data may inadvertently lead to premature closure of the diagnostic process. This study aimed to test the hypothesis that the application of a mnemonic checklist helps to stimulate more patient data collection, thus leading to better diagnostic consideration. METHODS: A total of 88 final year medical students were assigned to either an educational intervention group or a control group in a non-equivalent group post-test only design. Participants in the intervention group received a tutorial on the use of a mnemonic checklist aimed to minimize cognitive errors in clinical decision-making. Two weeks later, the participants in both groups were given a script concordance test consisting of 10 cases, with 3 items per case, to assess their clinical decisions when additional data are given in the case scenarios. RESULTS: The Mann-Whitney U-test performed on the total scores from both groups showed no statistical significance (U = 792, z = -1.408, p = 0.159). When comparisons were made for the first half and the second half of the SCT, it was found that participants in the intervention group performed significantly better than participants in the control group in the first half of the test, with median scores of 9.15 (IQR 8.00-10.28) vs. 8.18 (IQR 7.16-9.24) respectively, U = 642.5, z = -2.661, p = 0.008. No significant difference was found in the second half of the test, with the median score of 9.58 (IQR 8.90-10.56) vs. 9.81 (IQR 8.83-11.12) for the intervention group and control group respectively (U = 897.5, z = -0.524, p = 0.60). CONCLUSION: Checklist use in differential diagnoses consideration did show some benefit. However, this benefit seems to have been traded off by the time and effort in using it. More research is needed to determine whether this benefit could be translated into clinical practice after repetitive use. PMID- 29187173 TI - Anti-inflammatory evaluation of the methanolic extract of Taraxacum officinale in LPS-stimulated human umbilical vein endothelial cells. AB - BACKGROUND: Atherosclerosis is a chronic vascular inflammatory disease. Since even low-level endotoxemia constitutes a powerful and independent risk factor for the development of atherosclerosis, it is important to find therapies directed against the vascular effects of endotoxin to prevent atherosclerosis. Taraxacum officinale (TO) is used for medicinal purposes because of its choleretic, diuretic, antioxidative, anti-inflammatory, and anti-carcinogenic properties, but its anti-inflammatory effect on endothelial cells has not been established. METHODS: We evaluated the anti-inflammatory activity of TO filtered methanol extracts in LPS-stimulated human umbilical vein endothelial cells (HUVECs) by monocyte adhesion and western blot assays. HUVECs were pretreated with 100 MUg/ml TO for 1 h and then incubated with 1 MUg/ml LPS for 24 h. The mRNA and protein expression levels of the targets (pro-inflammatory cytokines and adhesion molecules) were analyzed by real-time PCR and western blot assays. We also preformed HPLC analysis to identify the components of the TO methanol extract. RESULTS: The TO filtered methanol extracts dramatically inhibited LPS-induced endothelial cell-monocyte interactions by reducing vascular cell adhesion molecule-1 and monocyte chemoattractant protein-1, and pro-inflammatory cytokine expression. TO suppressed the LPS-induced nuclear translocation of NF-kappaB, whereas it did not affect MAPK activation. CONCLUSIONS: Our findings demonstrated that methanol extracts of TO could attenuate LPS-induced endothelial cell activation by inhibiting the NF-kappaB pathway. These results indicate the potential clinical benefits and applications of TO for the prevention of vascular inflammation and atherosclerosis. PMID- 29187174 TI - Intra-tumor heterogeneity in breast cancer has limited impact on transcriptomic based molecular profiling. AB - BACKGROUND: Transcriptomic profiling of breast tumors provides opportunity for subtyping and molecular-based patient stratification. In diagnostic applications the specimen profiled should be representative of the expression profile of the whole tumor and ideally capture properties of the most aggressive part of the tumor. However, breast cancers commonly exhibit intra-tumor heterogeneity at molecular, genomic and in phenotypic level, which can arise during tumor evolution. Currently it is not established to what extent a random sampling approach may influence molecular breast cancer diagnostics. METHODS: In this study we applied RNA-sequencing to quantify gene expression in 43 pieces (2-5 pieces per tumor) from 12 breast tumors (Cohort 1). We determined molecular subtype and transcriptomic grade for all tumor pieces and analysed to what extent pieces originating from the same tumors are concordant or discordant with each other. Additionally, we validated our finding in an independent cohort consisting of 19 pieces (2-6 pieces per tumor) from 6 breast tumors (Cohort 2) profiled using microarray technique. Exome sequencing was also performed on this cohort, to investigate the extent of intra-tumor genomic heterogeneity versus the intra tumor molecular subtype classifications. RESULTS: Molecular subtyping was consistent in 11 out of 12 tumors and transcriptomic grade assignments were consistent in 11 out of 12 tumors as well. Molecular subtype predictions revealed consistent subtypes in four out of six patients in this cohort 2. Interestingly, we observed extensive intra-tumor genomic heterogeneity in these tumor pieces but not in their molecular subtype classifications. CONCLUSIONS: Our results suggest that macroscopic intra-tumoral transcriptomic heterogeneity is limited and unlikely to have an impact on molecular diagnostics for most patients. PMID- 29187175 TI - Standards for permanent tooth emergence in Czech children. AB - BACKGROUND: The aim of this study is to develop a population-specific reference for permanent tooth emergence among 4-15 years old Czech Republic children. The reference derived from this sample population are essential for pediatric dental diagnostics, orthodontic treatment planning, as well as anthropological and forensic applications. METHODS: In this cross-sectional epidemiological survey, dental examinations of 1,370 Czech children (696 girls (50,8%) and 674 boys (49,2%), whose parents or legal guardians all signed informed consent forms) from 11 elementary schools and kindergartens were performed in the classroom. During the examination, previously emerged permanent teeth (other than third molars), the child's age and gender were recorded. A tooth is defined as having erupted when at least any part of the crown penetrates the gingiva, and is clinically seen in the oral cavity. A logistic regression model was used to calculate the median emergence age per tooth for both genders and the total sample. The data was statistically processed (using IBM SPSS Statistics 23) and carried out at a deviation level of 0.05. The statistical significance of the differences in the emergence of permanent teeth (contralateral, intermaxillary, inter-gender differences) was evaluated by the McNemar test. RESULTS: No statistically significant differences were observed in the emergence times between right and left sides. In addition, mandibular teeth emerged earlier than the corresponding maxillary ones (with the exception of the first and second premolars). Permanent teeth were found to emerge sooner in girls. Furthermore, the greatest inter gender difference was observed in maxillary canines. CONCLUSIONS: The new data reported can now be used as standards when assessing permanent tooth emergence of Czech children. PMID- 29187176 TI - Frequency of DEA 1 antigen in 1037 mongrel and PUREBREED dogs in ITALY. AB - BACKGROUND: The prevalence of dog erythrocyte antigen (DEA 1) in canine population is approximately 40-60%. Often data are limited to a small number of breeds and/or dogs. The aims of this study were to evaluate frequency of DEA 1 in a large population of purebred and mongrel dogs including Italian native breeds and to recognize a possible association between DEA 1 and breed, sex, and genetic and phenotypical/functional classifications of breeds. Frequencies of DEA 1 blood group collected from screened/enrolled blood donors and from healthy and sick dogs were retrospectively evaluated. The breed and the sex were recorded when available. DEA 1 blood typing was assessed by immunocromatographic test on K3EDTA blood samples. The prevalence of DEA 1 antigen was statistically related to breed, gender, Federation Cynologique Internationale (FCI) and genotypic grouping. RESULTS: Sixty-two per cent dogs resulted DEA 1+ and 38% DEA 1-. DEA 1- was statistically associated with Dogo Argentino, Dobermann, German Shepherd, Boxer, Corso dogs, the molossian dogs, the FCI group 1, 2 and 3 and the genetic groups "working dogs" and "mastiff". DEA 1+ was statistically associated with Rottweiler, Briquet Griffon Vendeen, Bernese mountain dog, Golden Retriever, the hunting breeds, the FCI group 4, 6, 7 and 8 and the genetic groups "scent hounds" and "retrievers". No gender association was observed. CONCLUSIONS: Data obtained by this work may be clinically useful to drive blood donor enrollment and selection among different breeds. PMID- 29187177 TI - Work station learning activities: a flexible and scalable instrument for integrating across basic subjects in biomedical education. AB - BACKGROUND: Establishing innovative teaching programs in biomedical education involves dealing with several national and supra-national (i.e. European) regulations as well as with new pedagogical and demographic demands. We aimed to develop and validate a suitable instrument to integrate activities across preclinical years in all Health Science Degrees while meeting requirements of national quality agencies. METHODS: The new approach was conceived at two different levels: first, we identified potentially integrative units from different fields according to national learning goals established for each preclinical year (national quality agency regulations). Secondly, we implemented a new instrument that combines active methodologies in Work Station Learning Activities (WSLA), using clinical scenarios as a guiding common thread to instruct students from an integrated perspective. We evaluated students' perception through a Likert-type survey of a total of 118 students enrolled in the first year of the Bachelor's Degree in Medicine. RESULTS: Our model of integrated activities through WSLA is feasible, scalable and manageable with large groups of students and a minimum number of instructors, two major limitations in many medical schools. Students' perception of WSLA was positive in overall terms. Seventy nine percent of participants stated that WSLA sessions were more useful than non-integrated activities. Eighty three percent confirmed that the WSLA methodology was effective at integrating concepts covered by different subjects. CONCLUSIONS: The WSLA approach is a flexible and scalable instrument for moving towards integrated curricula, and it can be successfully adapted to teach basic subjects in preclinical years of Health Science degrees. WSLA can be applied to large groups of students in a variety of contexts or environments using clinical cases as connecting threads. PMID- 29187178 TI - Jia-Wei-Jiao-Tai-Wan ameliorates type 2 diabetes by improving beta cell function and reducing insulin resistance in diabetic rats. AB - BACKGROUND: Jia-Wei-Jiao-Tai-Wan (JWJTW), composed of Jiao-Tai-Wan (Cinnamomum cassia and Rhizoma coptidis) and other antidiabetic herbs, including Astragalus membranaceus, Herba Gynostemmatis, Radix Puerariae Lobatae, Folium Mori and Semen Trigonellae, is widely used to treat diabetes and has demonstrated a curative effect in the clinic, but the potential mechanism is unknown. This study aimed to explore the effects of JWJTW on diabetic rats and to clarify the underlying mechanism. METHODS: JWJTW was prepared, and the main components contained in the formula were identified by high-performance liquid chromatography (HPLC) fingerprint analysis. Diabetic rats induced by streptozotocin (STZ) and a high sucrose-high-fat diet were treated with two concentrations of JWJTW (1.025 and 2.05 g/kg/d) for 100 days. The oral glucose tolerance test (OGTT), insulin release test (IRT) and insulin tolerance test (ITT) were performed to measure the glycometabolism of the diabetic rats at the end of the treatment period. Blood was collected to determine the serum lipid levels of the diabetic rats. Nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-px) were detected in pancreas homogenates to analyze the oxidative stress in the pancreata of diabetic rats, and the expression levels of pancreatic and duodenal homeobox 1 (PDX-1) and insulin in the pancreas were tested by Western blot to measure pancreatic islet function. In addition, Western blots were used to measure the expression of proteins related to the insulin signaling pathway in skeletal muscle of the diabetic rats. RESULTS: The results showed that the administration of JWJTW could ameliorate impairments in glucose tolerance, insulin release function and insulin tolerance in diabetic rats. JWJTW could also dose-dependently reduce serum lipid levels in diabetic rats. JWJTW restrained oxidative stress by decreasing the expression of NO and MDA and increasing the expression of SOD and GSH-px. JWJTW improved the function of pancreatic beta cells by increasing PDX-1 and insulin expression. In addition, JWJTW restored the impaired insulin signaling; upregulated phospho-insulin receptor (pInsR) expression, insulin receptor substrate (IRS) tyrosine phosphorylation, phosphatidylinositol 3-kinase (PI3K) (p85), and glucose transporter 4 (GLUT4) expression; and downregulated the serine phosphorylation of IRS. CONCLUSIONS: This study suggests that JWJTW can ameliorate type 2 diabetes by improving beta cell function and reducing insulin resistance in diabetic rats. PMID- 29187179 TI - The learning environment of paediatric interns in South Africa. AB - BACKGROUND: South African (SA) paediatric interns (recently qualified medical graduates) work in a high disease burdened and resource deficient environment for two years, prior to independent practice. Perceptions of this learning environment (LE) influences their approaches to training as well as the outcomes of this period of development. Obstacles to creating a supportive LE and supervisor interaction affects the quality of this training. Measuring perceptions of the LE with validated instruments can help inform improvements in learning during this crucial period of medical education. METHODS: The aims of this study was to determine the psychometric qualities of the Postgraduate Hospital Educational Environment Measure (PHEEM) amongst paediatric interns across four hospital complexes in South Africa and to measure the LE as perceived by both interns and their supervisors. Construct validity was tested using factor analysis and internal consistency was measured with Cronbach's alpha. RESULTS: A total of 209 interns and 60 supervisors (69% intern response rate) responded to the questionnaire. The PHEEM was found to be very reliable with an overall Cronbach's alpha of 0.943 and 0.874 for intern and supervisors respectively. Factor analysis using a 3-factor solution accounted for 42% of the variance with the teaching subscale having the best fit compared with the other sub-scales of the original tool. Most interns perceived the learning environment as being more positive than negative however, their perceptions differed significantly from that of their supervisors. Poor infrastructural support from institutions, excessive workloads and inadequate supervision were factors preventing optimal training of paediatric interns. CONCLUSIONS: The SA version of the PHEEM tool used was found to be a reliable and valid instrument for use in interns amongst high disease burdened contexts. Various obstacles to creating an ideal learning environment for paediatric interns were identified to be in need of urgent review. Key differences in perceptions of an ideal learning environment between interns and their supervisors need to be fully explored as these may result in sub-optimal supervision and mentoring. PMID- 29187180 TI - Use of autogenous onlay bone graft for uncontained tibial bone defects in primary total knee arthroplasty. AB - BACKGROUND: The use of autogenous bone graft is a well-known technique for reconstruction of tibial bone defects in primary total knee arthroplasty (TKA). In cases where the size of the bone graft is inappropriate, the stability of bone graft fixation and subsequent bone graft to host bone incorporation may be compromised. We describe a simple and reliable technique of reconstruction in a proximal tibia bone defect at the time of primary TKA by using autogenous onlay bone graft (AOBG). METHODS: Records were reviewed of 19 patients (mean age, 72 years) who underwent primary TKA using AOBG without the additional allogenous bone or metal augments, between August 2013 and August 2014. RESULTS: Mean Knee Society score (KSS) in the 22 knees was significantly higher postoperatively than preoperatively (92 +/- 4 vs. 30 +/- 7, P < 0.001). The mean range of motion (ROM) in the 22 knees, which was 106 +/- 12 degrees preoperatively, improved to 112 +/ 10 degrees at last follow-up, but this difference was not significant (P = 0.32). No migration of implants and presence of radiolucent lines at the bone cement-prosthesis interface were observed. Furthermore, the serial radiographs of 19 patients had a mean time of 3.2 months (range, 2.7-4.4 months) for solid union with cross trabeculation between the proximal tibial bone and graft. CONCLUSIONS: This simple AOBG supplement technique may biologically promote graft to host bone healing by enhancing fixation stability without the additional fixatives and assist the surgeon in managing the varying nature of uncontained bone defects. TRIAL REGISTRATION: Trial registration number: KCT0002328 , May 15, 2017. PMID- 29187181 TI - Could cone-beam computed tomography demonstrate the lateral accessory canals? AB - BACKGROUND: Recently, using cone-beam computed tomography (CBCT) to assess root canal morphology has become popular; however, few studies have examined its efficiency to assess the entire root canals, including the tiny lateral and accessory canals (LACs). This study aimed to assess the ability of CBCT to evaluate the root canal of mandibular incisors at three different scanning settings, compared with the canal staining and tooth clearing (CS) technique as the gold standard. METHODS: CBCT images of 70 extracted mandibular incisors were taken using NewTom VG CBCT at high-resolution scan mode (HZ), zoom scan mode (ZS), and full scan mode (FS), with different scanning settings. A radiologist, a postgraduate student, and an endodontist assessed the root canal morphology in a blinded manner. The number of root canals (NC), canal configuration according to Vertucci's classification (VC), and LACs were evaluated twice by each evaluator using the CBCT images, in comparison with CS. Comparisons of the differences were used the chi-square test, and the intra-evaluator and inter-evaluator agreement were used the Kappa statistics; the significance level was set at 0.05. RESULTS: The voxel dimension of HZ, ZS and FS modes were 0.125 mm, 0.20 mm and 0.25 mm respectively, and the HZ mode had significant increased scanning doses. For NC, the diagnostic accuracy was >90% in all three modes, with no significant difference among the evaluators and modes. VC and LAC could only be evaluated in HZ mode. For VC, the accuracies were 97.1%, 94.3%, and 92.9% respectively, with no significant differences among the three evaluators. For LAC, the accuracies were 80.0%, 13.3%, and 33.3% respectively, and there were significant differences among the three evaluators. Intra-evaluator agreement was excellent, with the kappa values indicating "perfect" to "substantial" agreement. Inter-evaluator agreement was excellent for NC and VC; however, Kappa values could not be analyzed due to LACs detected were so variable. CONCLUSIONS: As far as possible, the HZ mode should be chosen to demonstrate the root canal system, and partial LACs could be detected using this mode; however, the potential benefit of the diagnostic information must be weighed against the increased radiation dose. PMID- 29187182 TI - Sacroiliac joint tuberculosis: surgical management by posterior open-window focal debridement and joint fusion. AB - BACKGROUND: Sacroiliac joint tuberculosis(SJT) is relatively uncommon, but it may cause severe sacroiliac joint destruction and functional disorder. Few studies in the literature have been presented on SJT, reports of surgical treatment for SJT are even fewer. In this study, we retrospectively reviewed surgical management of patients with severe SJT of 3 different types and proposed to reveal the clinical manifestations and features and aim to determine the efficiency and security of such surgical treatment. METHODS: We reviewed 17 patients with severe SJT of 3 different types who underwent posterior open-window focal debridement and bone graft for joint fusion. Among them,five patients with anterior sacral abscess had anterior abscess curettage before debridement. Two patients with lumbar vertebral tuberculosis received one-stage posterior tuberculous debridement, interbody fusion and instrumentation. Follow-up was performed 36 months (26 to 45 months) using the following parameters: erythrocyte sedimentation rate(ESR), status of joint bony fusion on CT scan, visual analogue scale (VAS) and the Oswestry Disability Index (ODI). RESULTS: Buttock pain and low back pain were progressively relieved with time. 6 months later, pain was not obvious, and ESR resumed to normal levels within 3 months. Solid fusion of the sacroiliac joint occurred within 12 months in all cases. No complications or recurrence occurred. At final follow-up, all patients had no pain or only minimal discomfort over the affected joint and almost complete functional recovery. CONCLUSIONS: Posterior open-window focal debridement and joint fusion is an efficient and secure surgical method to treat severe SJT. If there is an abscess in the front of the sacroiliac joint, anterior abscess curettage should be performed as a supplement. PMID- 29187183 TI - Low bone turnover in premenopausal women with type 2 diabetes mellitus as an early process of diabetes-associated bone alterations: a cross-sectional study. AB - BACKGROUND: Individuals with Diabetes Mellitus (DM) are at increased risk for fracture due to the decrease in bone strength and quality. Serum procollagen type I intact N-terminal (P1NP) and serum C-terminal cross-linking telopeptide of type I collagen (CTX) as markers of bone formation and resorption, respectively, have been reported to be decreased in T2DM. It remains unclear whether diabetes associated alterations in the bone turnover of T2DM individuals are related to the longer duration of the disease or may occur earlier. Furthermore, previous studies on BTMs in T2DM individuals have mostly been done in postmenopausal women with T2DM, which might have masked the DM-induced alterations of bone turnover with concurrent estrogen deficiency. This study aims to assess the levels of serum P1NP and CTX as markers of bone turnover in premenopausal women with and without T2DM. METHODS: This cross-sectional study involves 41 premenopausal women with T2DM, and 40 premenopausal women without DM. Sampling was done consecutively. P1NP and CTX measurement was done using the electrochemi luminescence immunoassay (ECLIA) method. Other data collected include levels of HbA1C, ALT, creatinine, eGFR and lipid profile. RESULTS: Median (interquartile range) P1NP in T2DM is 29.9 ng/ml (24.7-41.8 ng/ml), while in non-DM is 37.3 ng/ml, (30.8-47.3 ng/ml; p = 0.007). Median (interquartile range) CTX in T2DM is 0.161 ng/ml (0.106-0.227 ng/ml), while in non-DM is 0.202 ng/ml (0.166-0.271 ng/ml; p = 0.0035). Levels of P1NP and CTX in the T2DM group did not correlate with the duration of disease, age, BMI or the levels of HbA1C. CONCLUSIONS: Premenopausal women with T2DM indeed have lower bone turnover when compared with non-DM controls. This significantly lower bone turnover process starts relatively early in the premenopausal age, independent of the duration of DM. Gaining understanding of the early pathophysiology of altered bone turnover may be key in developing preventive strategies for diabetoporosis. PMID- 29187185 TI - In-hospital prescription changes and documentation in the medical records of the primary care provider: results from a medical record review study. AB - BACKGROUND: An increasing number of transitions due to substitution of care of more complex patients urges insight in and improvement of transitional medication safety. While lack of documentation of prescription changes and/or lack of information exchange between settings likely cause adverse drug events, frequency of occurrence of these causes is not clear. Therefore, we aimed at determining the frequency of in-hospital patients' prescription changes that are not or incorrectly documented in their primary care provider's (PCP) medical record. METHODS: A medical record review study was performed in a database linking patients' medical records of hospital and PCP. A random sample (n = 600) was drawn from all 1399 patients who were registered at a participating primary care practice as well as the gastroenterology or cardiology department in 2013 of the University Medical Center Utrecht, the Netherlands. Outcomes were the number of in-hospital prescription changes that was not or incorrectly documented in the medical record of the PCP, and timeliness of documentation. RESULTS: Records of 390 patients included one or more primary-secondary care transitions; in total we identified 1511 transitions. During these transitions, 408 in-hospital prescription changes were made, of which 31% was not or incorrectly documented in the medical record of the PCP within the next 3 months. In case changes were documented, the median number of days between hospital visit and documentation was 3 (IQR 0-18). CONCLUSIONS: One third of in-hospital prescription changes was not or incorrectly documented in the PCP's record, which likely puts patients at risk of adverse drug events after hospital visits. Such flawed reliability of a routine care process is unacceptable and warrants improvement and close monitoring. PMID- 29187186 TI - A mobile and web-based clinical decision support and monitoring system for diabetes mellitus patients in primary care: a study protocol for a randomized controlled trial. AB - BACKGROUND: Physicians' guideline use rates for diagnosis, treatment and monitoring of diabetes mellitus (DM) is very low. Time constraints, patient overpopulation, and complex guidelines require alternative solutions for real time patient monitoring. Rapidly evolving e-health technology combined with clinical decision support and monitoring systems (CDSMS) provides an effective solution to these problems. The purpose of the study is to develop a user friendly, comprehensive, fully integrated web and mobile-based Clinical Decision Support and Monitoring System (CDSMS) for the screening, diagnosis, treatment, and monitoring of DM diseases which is used by physicians and patients in primary care and to determine the effectiveness of the system. METHODS: The CDSMS will be based on evidence-based guidelines for DM disease. A web and mobile-based application will be developed in which the physician will remotely monitor patient data through mobile applications in real time. The developed CDSMS will be tested in two stages. In the first stage, the usability, understandability, and adequacy of the application will be determined. Five primary care physicians will use the developed application for at least 16 DM patients. Necessary improvements will be made according to physician feedback. In the second phase, a parallel, single-blind, randomized controlled trial will be implemented. DM diagnosed patients will be recruited for the CDSMS trial by their primary care physicians. Ten physicians and their 439 patients will be involved in the study. Eligible participants will be assigned to intervention and control groups with simple randomization. The significance level will be accepted as p < 0.05. In the intervention group, the system will make recommendations on patient monitoring, diagnosis, and treatment. These recommendations will be implemented at the physician's discretion. Patients in the control group will be treated by physicians according to current DM treatment standards. Patients in both groups will be monitored for 6 months. Patient data will be compared between 0th and 6th month of the study. . Clinical and laboratory outcomes will be assessed in person while others will be self-assessed online. DISCUSSION: The developed system will be the first of its kind to utilize evidence based guidelines to provide health services to DM patients. TRIAL REGISTRATION: ClinicalTrials.gov NCT02917226 . 28 September 2016. PMID- 29187184 TI - Rheumatic heart disease: infectious disease origin, chronic care approach. AB - BACKGROUND: Rheumatic heart disease (RHD) is a chronic cardiac condition with an infectious aetiology, causing high disease burden in low-income settings. Affected individuals are young and associated morbidity is high. However, RHD is relatively neglected due to the populations involved and its lower incidence relative to other heart diseases. METHODS AND RESULTS: In this narrative review, we describe how RHD care can be informed by and integrated with models of care developed for priority non-communicable diseases (coronary heart disease), and high-burden communicable diseases (tuberculosis). Examining the four-level prevention model (primordial through tertiary prevention) suggests primordial and primary prevention of RHD can leverage off existing tuberculosis control efforts, given shared risk factors. Successes in coronary heart disease control provide inspiration for similarly bold initiatives for RHD. Further, we illustrate how the Chronic Care Model (CCM), developed for use in non-communicable diseases, offers a relevant framework to approach RHD care. Systems strengthening through greater integration of services can improve RHD programs. CONCLUSION: Strengthening of systems through integration/linkages with other well-performing and resourced services in conjunction with policies to adopt the CCM framework for the secondary and tertiary prevention of RHD in settings with limited resources, has the potential to significantly reduce the burden of RHD globally. More research is required to provide evidence-based recommendations for policy and service design. PMID- 29187187 TI - Syndromic surveillance for West Nile virus using raptors in rehabilitation. AB - BACKGROUND: Wildlife rehabilitation centers routinely gather health-related data from diverse species. Their capability to signal the occurrence of emerging pathogens and improve traditional surveillance remains largely unexplored. This paper assessed the utility for syndromic surveillance of raptors admitted to The Raptor Center (TRC) to signal circulation of West Nile Virus (WNV) in Minnesota between 1990 and 2014. An exhaustive descriptive analysis using grouping time series structures and models of interrupted times series was conducted for indicator subsets. RESULTS: A total of 13,080 raptors were monitored. The most representative species were red-tailed hawks, great horned owls, Cooper's hawks, American kestrels and bald eagles. Results indicated that temporal patterns of accessions at the TRC changed distinctively after the incursion of WNV in 2002. The frequency of hawks showing WNV-like signs increased almost 3 times during July and August, suggesting that monitoring of hawks admitted to TRC with WNV like signs could serve as an indicator of WNV circulation. These findings were also supported by the results of laboratory diagnosis. CONCLUSIONS: This study demonstrates that monitoring of data routinely collected by wildlife rehabilitation centers has the potential to signal the spread of pathogens that may affect wild, domestic animals and humans, thus supporting the early detection of disease incursions in a region and monitoring of disease trends. Ultimately, data collected in rehabilitation centers may provide insights to efficiently allocate financial and human resources on disease prevention and surveillance. PMID- 29187188 TI - Massive pelvic recurrence of uterine leiomyomatosis with intracaval-intracardiac extension: video case report and literature review. AB - BACKGROUND: Uterine leiomyomas represent the gynecological neoplasm with the highest prevalence worldwide. This apparently benign pathological entity may permeate into the venous system causing the so-called intravenous leiomyomatosis of the uterus (IVL). IVL may seldom extend to large caliber veins and reach the right cardiac chambers or pulmonary arteries and cause signs of right sided congestive heart failure and sudden death. Due to its low incidence, however, IVL with intracardiac extension is often misdiagnosed resulting in deferred treatment. No consensus has been obtained regarding the standard surgical approach to be used for this rare condition. We describe the case of a massive pelvic recurrence of uterine leiomyomatosis with intracardiac extension and provide a review of the literature, analyzing management and surgical outcomes. CASE PRESENTATION: We present the case of a 46-year-old premenopausal woman presenting with lower-extremity edema, recurrent syncopes and a history of subtotal hysterectomy for multiple uterine fibroids. She was diagnosed with pelvic recurrence of uterine leiomyomatosis and IVL with cardiac involvement. A two-stage surgical excision of the intracardiac-intracaval mass and pelvic leiomyomatosis was performed. The patient had an uneventful recovery and no evidence of recurrence was observed on follow-up. CONCLUSIONS: By virtue of the rarity of the present pathology, awareness is widely scarce and diagnosis is often delayed. Early recognition is difficult due to initial aspecific and subtle clinical manifestations. Nevertheless, suspicion should be held high in premenopausal women with known history of uterine leiomyomata, presenting with cardiovascular symptoms and evidence of a free-floating mass within the right cardiac chambers. In-depth imaging is crucial for defining its anatomical origin and relations. Prompt surgical treatment with radical excision of pelvic and intravenous leiomyomatosis guarantees favorable outcomes and excellent prognosis with low rates of recurrence, whereas delayed diagnosis and treatment exposes to increased risk of congestive heart failure and sudden death. PMID- 29187189 TI - Operational integration in primary health care: patient encounters and workflows. AB - BACKGROUND: Despite several countrywide attempts to strengthen and standardise the primary healthcare (PHC) system, Greece is still lacking a sustainable, policy-based model of integrated services. The aim of our study was to identify operational integration levels through existing patient care pathways and to recommend an alternative PHC model for optimum integration. METHODS: The study was part of a large state-funded project, which included 22 randomly selected PHC units located across two health regions of Greece. Dimensions of operational integration in PHC were selected based on the work of Kringos and colleagues. A five-point Likert-type scale, coupled with an algorithm, was used to capture and transform theoretical framework features into measurable attributes. PHC services were grouped under the main categories of chronic care, urgent/acute care, preventive care, and home care. A web-based platform was used to assess patient pathways, evaluate integration levels and propose improvement actions. Analysis relied on a comparison of actual pathways versus optimal, the latter ones having been identified through literature review. RESULTS: Overall integration varied among units. The majority (57%) of units corresponded to a basic level. Integration by type of PHC service ranged as follows: basic (86%) or poor (14%) for chronic care units, poor (78%) or basic (22%) for urgent/acute care units, basic (50%) for preventive care units, and partial or basic (50%) for home care units. The actual pathways across all four categories of PHC services differed from those captured in the optimum integration model. Certain similarities were observed in the operational flows between chronic care management and urgent/acute care management. Such similarities were present at the highest level of abstraction, but also in common steps along the operational flows. CONCLUSIONS: Existing patient care pathways were mapped and analysed, and recommendations for an optimum integration PHC model were made. The developed web platform, based on a strong theoretical framework, can serve as a robust integration evaluation tool. This could be a first step towards restructuring and improving PHC services within a financially restrained environment. PMID- 29187191 TI - Fostering development of nursing practices to support integrated care when implementing integrated care pathways: what levers to use? AB - BACKGROUND: Care integration has been the focus of recent health system reforms. Given their functions at all levels of the care continuum, nurses have a substantial and primordial role to play in such integration processes. The aim of this study was to identify levers and strategies that organizations can use to support the development of a nursing practice aligned with the requirements of care integration in a health and social services centre (HSSC) in Quebec. METHODS: The research design was a cross-sectional descriptive qualitative study based on a single case study with nested levels of analysis. The case was a public, multi-disciplinary HSSC in a semi-urban region of Quebec. Semi-structured interviews with 37 persons (nurses, professionals, managers, administrators) allowed for data saturation and ensured theoretical representation by covering four care pathways constituting different care integration contexts. Analysis involved four steps: preparing a predetermined list of codes based on the reference framework developed by Minkman (2011); coding transcript content; developing general and summary matrices to group observations for each care pathway; and creating a general model showing the overall results for the four pathways. RESULTS: The organization's capacity for response with regard to developing an integrated system of services resulted in two types of complementary interventions. The first involved investing in key resources and renewing organizational structures; the second involved deploying a series of organizational and clinical-administrative processes. In resource terms, integration efforts resulted in setting up new strategic services, re-arranging physical infrastructures, and deploying new technological resources. Organizational and clinical-administrative processes to promote integration involved renewing governance, improving the flow of care pathways, fostering continuous quality improvement, developing new roles, promoting clinician collaboration, and strengthening care providers' capacities. However, progress in these areas was offset by persistent constraints. CONCLUSIONS: The results highlight key levers organizations can use to foster the implementation and institutionalization of integrative nursing practices. They show that progress in this area requires a combination of strategies using multiple complementary levers. They also suggest that such progress calls for rethinking not only the deployment of certain organizational resources and structures, but also a series of organizational and clinical processes. PMID- 29187190 TI - Ethical considerations in forensic genetics research on tissue samples collected post-mortem in Cape Town, South Africa. AB - BACKGROUND: The use of tissue collected at a forensic post-mortem for forensic genetics research purposes remains of ethical concern as the process involves obtaining informed consent from grieving family members. Two forensic genetics research studies using tissue collected from a forensic post-mortem were recently initiated at our institution and were the first of their kind to be conducted in Cape Town, South Africa. MAIN BODY: This article discusses some of the ethical challenges that were encountered in these research projects. Among these challenges was the adaptation of research workflows to fit in with an exceptionally busy service delivery that is operating with limited resources. Whilst seeking guidance from the literature regarding research on deceased populations, it was noted that next of kin of decedents are not formally recognised as a vulnerable group in the existing ethical and legal frameworks in South Africa. The authors recommend that research in the forensic mortuary setting is approached using guidance for vulnerable groups, and the benefit to risk standard needs to be strongly justified. Lastly, when planning forensic genetics research, consideration must be given to the potential of uncovering incidental findings, funding to validate these findings and the feedback of results to family members; the latter of which is recommended to occur through a genetic counsellor. CONCLUSION: It is hoped that these experiences will contribute towards a formal framework for conducting forensic genetic research in medico-legal mortuaries in South Africa. PMID- 29187192 TI - Comprehensive metabolic profiling of chronic low-grade inflammation among generally healthy individuals. AB - BACKGROUND: Inflammation occurs as an immediate protective response of the immune system to a harmful stimulus, whether locally confined or systemic. In contrast, a persisting, i.e., chronic, inflammatory state, even at a low-grade, is a well known risk factor in the development of common diseases like diabetes or atherosclerosis. In clinical practice, laboratory markers like high-sensitivity C reactive protein (hsCRP), white blood cell count (WBC), and fibrinogen, are used to reveal inflammatory processes. In order to gain a deeper insight regarding inflammation-related changes in metabolism, the present study assessed the metabolic patterns associated with alterations in inflammatory markers. METHODS: Based on mass spectrometry and nuclear magnetic resonance spectroscopy we determined a comprehensive panel of 613 plasma and 587 urine metabolites among 925 apparently healthy individuals. Associations between inflammatory markers, namely hsCRP, WBC, and fibrinogen, and metabolite levels were tested by linear regression analyses controlling for common confounders. Additionally, we tested for a discriminative signature of an advanced inflammatory state using random forest analysis. RESULTS: HsCRP, WBC, and fibrinogen were significantly associated with 71, 20, and 19 plasma and 22, 3, and 16 urine metabolites, respectively. Identified metabolites were related to the bradykinin system, involved in oxidative stress (e.g., glutamine or pipecolate) or linked to the urea cycle (e.g., ornithine or citrulline). In particular, urine 3'-sialyllactose was found as a novel metabolite related to inflammation. Prediction of an advanced inflammatory state based solely on 10 metabolites was well feasible (median AUC: 0.83). CONCLUSIONS: Comprehensive metabolic profiling confirmed the far-reaching impact of inflammatory processes on human metabolism. The identified metabolites included not only those already described as immune-modulatory but also completely novel patterns. Moreover, the observed alterations provide molecular links to inflammation-associated diseases like diabetes or cardiovascular disorders. PMID- 29187193 TI - Paediatric case mix in a rural clinical school is relevant to future practice. AB - BACKGROUND: Exposure to a representative case mix is essential for clinical learning, with logbooks established as a way of demonstrating patient contacts. Few studies have reported the paediatric case mix available to geographically distributed students within the same medical school. Given international interest in expanding medical teaching locations to rural contexts, equitable case exposure in rural relative to urban settings is topical. The Rural Clinical School of Western Australia locates students up to 3500 km from the urban university for an academic year. There is particular need to examine paediatric case mix as a study reported Australian graduates felt unprepared for paediatric rotations. We asked: Does a rural clinical school provide a paediatric case mix relevant to future practice? How does the paediatric case mix as logged by rural students compare with that by urban students? METHODS: The 3745 logs of 76 urban and 76 rural consenting medical students were categorised by presenting symptoms and compared to the Australian Institute of Health and Welfare (AIHW) database Major Diagnostic Categories (MDCs). RESULTS: Rural and urban students logged core paediatric cases, in similar order, despite the striking difference in geographic locations. The pattern of overall presenting problems closely corresponded to Australian paediatric hospital admissions. Rural students logged 91% of cases in secondary healthcare settings; urban students logged 90% of cases in tertiary settings. The top four presenting problems were ENT/respiratory, gastrointestinal/urogenital, neurodevelopmental and musculoskeletal; these made up 60% of all cases. Rural and urban students logged similar proportions of infants, children and adolescents, with a variety of case morbidity. CONCLUSIONS: Rural clinical school students logged a mix of core paediatric cases relevant to illnesses of Australian children admitted to public hospitals, with similar order and pattern by age group to urban students, despite major differences in clinical settings. Logged cases met the curriculum learning outcomes of graduates. Minor variations were readily addressed via recommendations about logging. This paper provides evidence of the legitimacy of student logs as useful tools in affirming appropriate paediatric case mix. It validates the rural clinical school context as appropriate for medical students to prepare for future clinical paediatric practice. PMID- 29187194 TI - Treatment effects of renin-angiotensin aldosterone system blockade on kidney failure and mortality in chronic kidney disease patients. AB - BACKGROUND: Chronic kidney disease (CKD) is a leading cause of death before and after onset of end-stage renal disease (ESRD). Knowing treatments that can delay disease progression will lead to reduced mortality. We therefore aimed to estimate the effectiveness of renin angiotensin aldosterone system (RAAS) blockade on CKD progression. METHODS: We conducted a retrospective CKD cohort at Ubon Ratchathani province, Thailand from 1997 to 2011. ESRD was defined as estimated glomerular filtration rate (eGFR) <15 ml/min/1.73 m2, dialysis, or kidney transplantation. All-cause mortality was verified until December 31, 2011. A counterfactual-framework was applied to estimate the effectiveness of RAAS blockade on outcomes, i.e., ESRD, death before and after ESRD. RAAS blockade was categorized according to duration of use <0.25 year, 0.25-1 year (RAAS1), and >1 year (RAAS2). An augmented inverse-probability weighting (AIPW) method was used to estimate potential-outcome mean (POM) and average treatment-effect (ATE). Multi-logit and Poisson regressions were used for treatment and outcome models, respectively. Analyses were stratified by ESRD, death before/after ESRD for diabetic and non-diabetic groups. STATA 14.0 was used for statistical analyses. RESULTS: Among 15,032 diabetic patients, 2346 (15.6%), 2351 (18.5%), and 1607 (68.5%) developed ESRD, died before ESRD, and died after ESRD, respectively. Only RAAS2 effect was significant on ESRD, death before and after ESRD. The ESRD rates were 12.9%, versus 20.0% for RAAS2 and non-RAAS, respectively, resulted in significant risk differences (RD) of -7.2% (95% CI: -8.8%, -5.5%), and a numbers needed-to-treat (NNT) of 14. Death rates before ESRD for these corresponding groups were 14.4% (12.9%, 15.9%) and 19.6% (18.7%, 20.4%) with a NNT of 19. Death rates after ESRD in RAAS2 was lower than non-RASS group (i.e., 62.8% (55.5%, 68.9%) versus 68.1% (65.9%, 70.4%)) but this was not significant. RAAS2 effects on ESRD and death before ESRD were persistently significant in non-diabetic patients (n = 17,074) but not for death after ESRD with the NNT of about 15 and 16 respectively. CONCLUSIONS: Receiving RAAS blockade for 1 year or longer could prevent both CKD progression to ESRD and premature mortality. PMID- 29187195 TI - Prevalence, antimicrobial susceptibility and risk factors associated with non typhoidal Salmonella on Ugandan layer hen farms. AB - BACKGROUND: Non-typhoidal Salmonella (NTS) are among the leading global foodborne pathogens and a significant public health threat. Their occurrence in animal reservoirs and their susceptibilities to commonly used antimicrobials are poorly understood in developing countries. The aim of this study was to estimate the prevalence, determine antimicrobial susceptibility and identify risk factors associated with NTS presence in laying hen farms in Uganda through a cross sectional study. RESULTS: Pooled faecal samples were collected from 237 laying hen farms and these were analysed for NTS following standard laboratory procedures. In total, 49 farms (20.7%; 95% Confidence interval (CI): 15.6-25.6%) were positive for NTS presence. Altogether, ten Salmonella serotypes were identified among the confirmed 78 isolates, and the predominant serotypes were Salmonella Newport (30.8%), S. Hadar (14.1%), S. Aberdeen (12.8%), S. Heidelberg (12.8%), and S. Bolton (12.8%). Phenotypic antimicrobial resistance was detected in 45(57.7%) of the isolates and the highest resistance was against ciprofloxacin (50.0%) followed by sulphonamides (26.9%) and sulphamethoxazole/trimethoprim (7.7%). Resistance was significantly associated with sampled districts (p = 0.034). Resistance to three or more drugs, multi-drug resistance (MDR) was detected in 12 (15.4%) of the isolates, 9 (75%) of these were from Wakiso district. A multivariable logistic model identified large farm size (OR = 7.0; 95% CI: 2.5-19.8) and the presence of other animal species on the farm (OR = 5.9; 95% CI: 2.1-16.1) as risk factors for NTS prevalence on farms. Having a separate house for birds newly brought to the farms was found to be protective (OR = 0,4; 95% CI: 0.2-0.8). CONCLUSION: This study has highlighted a high prevalence and diversity of NTS species in laying hen farms in Uganda and identified associated risk factors. In addition, it has demonstrated high levels of antimicrobial resistance in isolates of NTS. This could be because of overuse or misuse of antimicrobials in poultry production. Also importantly, the insights provided in this study justifies a strong case for strengthening One Health practices and this will contribute to the development of NTS control strategies at local, national and international levels. PMID- 29187196 TI - Development of a monitoring instrument to assess the performance of the Swiss primary care system. AB - BACKGROUND: The Swiss health system is customer-driven with fee-for-service paiement scheme and universal coverage. It is highly performing but expensive and health information systems are scarcely implemented. The Swiss Primary Care Active Monitoring (SPAM) program aims to develop an instrument able to describe the performance and effectiveness of the Swiss PC system. METHODS: Based on a Literature review we developed a conceptual framework and selected indicators according to their ability to reflect the Swiss PC system. A two round modified RAND method with 24 inter-/national experts took place to select primary/secondary indicators (validity, clarity, agreement). A limited set of priority indicators was selected (importance, priority) in a third round. RESULTS: A conceptual framework covering three domains (structure, process, outcome) subdivided into twelve sections (funding, access, organisation/ workflow of resources, (Para-)Medical training, management of knowledge, clinical /interpersonal care, health status, satisfaction of PC providers/ consumers, equity) was generated. 365 indicators were pre-selected and 335 were finally retained. 56 were kept as priority indicators.- Among the remaining, 199 were identified as primary and 80 as secondary indicators. All domains and sections are represented. CONCLUSION: The development of the SPAM program allowed the construction of a consensual instrument in a traditionally unregulated health system through a modified RAND method. The selected 56 priority indicators render the SPAM instrument a comprehensive tool supporting a better understanding of the Swiss PC system's performance and effectiveness as well as in identifying potential ways to improve quality of care. Further challenges will be to update indicators regularly and to assess validity and sensitivity-to-change over time. PMID- 29187197 TI - Changes in clavicle length in acute fractures within 3 weeks: a prospective ultrasonographic study of 59 patients. AB - BACKGROUND: Within traumatology a common indication for acute surgery of fractured clavicles is bone shortening over 2 cm. This indication is among but a few indications; which are recommended to be treated operatively within the very first weeks after a fracture. Theoretically clavicle fractures could become less shortened over time due to decreasing muscle pull. If this reduced shortening does indeed happen, some patients with initial bone shortening over 2 cm could perhaps be treated conservatively? However, it is unknown what happens to the length of the clavicle within the first weeks after a fracture. The aim of this study was to investigate if the length of the fresh fractured clavicles changes within the first three weeks. METHODS: Rested length measurements using navigation ultrasound were done on 59 patients with a fractured clavicle. Measurements were performed within the first three weeks after a lateral or mid clavicular fracture. The inclusion period was from March 2014 to February 2016. Median age was 40 years and age range was 18-81 years. The data was analyzed using mixed linear models. RESULTS: The clavicle length showed no change within the first three weeks after fracture (p = 0.24). CONCLUSION: Fractured clavicles retain their length for the first three weeks. PMID- 29187198 TI - Preliminary reference intervals and the impact of citrate storage time for thrombelastography in cats including delta and the velocity curve. AB - BACKGROUND: Thrombelastography is a useful tool in assessment of hemostasis. Beside the traditional variables, the velocity curve and the variable delta have lately earned attention. The velocity curve provides knowledge about the speed of clot formation including information about thrombin generation. Delta, which only reflects enzymatic coagulation, allows the determination of the origin of hypercoagulability when compared to clot rigidity, a variable that reflects both platelet and enzymatic activity. The aim was to establish preliminary reference intervals for feline thrombelastography including the velocity curve variables and delta obtained after 60 min of storage including the assessment of coefficients of variation. Furthermore, the effect of citrate storage time (30 versus 60 min) on feline thrombelastography will be determined. RESULTS: Prolonged storage times significantly reduced reaction (R) (P = 0.019) and clotting (K) (P = 0.008) times, split point (SP) (P = 0.019) and time to maximum rate of thrombus generation (TMRTG) (P = 0.023) values whereas maximum rate of thrombus generation (MRTG) significantly increased (P = 0.040). Preliminary reference intervals: R (min): 2.7-18.1; K (min): 0.8-3.9; alpha ( degrees ): 27.6 75.2; maximum amplitude (mm): 18.5-62.5; clot rigidity (dyn/cm2): 1.2-8.2; coagulation index: -4.6 - 2.6; SP (min): 2.4-15.4; delta (min): 0.3-3.1; thrombus generation (mm/min): 255.3-751.2; MRTG (mm/min): 4.0-19.3; TMRTG (min): 3.5-22.0; maximum rate of lysis (mm/min): 0.0-4.7 and time to maximum rate of lysis (min): 0.4-55.8. CONCLUSION: Storage for 60 versus 30 min induces hypercoagulable tracings including the velocity curve, some of which variables (MRTG, TMRTG) might function as sensitive markers for changes in the coagulation activity. Because of the impact of citrate storage time on thrombelastography, reference intervals have to be established using a specific and constant storage time in each laboratory. PMID- 29187199 TI - Novel ELISA method as exploratory tool to assess immunity induced by radiated attenuated sporozoites to decipher protective immunity. AB - BACKGROUND: Whole parasite vaccines provide a unique opportunity for dissecting immune mechanisms and identify antigens that are targeted by immune responses which have the potential to mediate sterile protection against malaria infections. The radiation attenuated sporozoite (PfSPZ) vaccine has been considered the gold standard for malaria vaccines because of its unparalleled efficacy. The immunogenicity of this and other vaccines continues to be evaluated by using recombinant proteins or peptides of known sporozoite antigens. This approach, however, has significant limitations by relying solely on a limited number of known pathogen-associated immune epitopes. Using the full range of antigens expressed by the sporozoite will enable the comprehensive immune profiling of humoral immune responses induced by whole parasite vaccines. To address this challenge, a novel ELISA based on sporozoites was developed. RESULTS: The SPZ-ELISA method described in this report can be performed with either freshly dissected sporozoites or with cryopreserved sporozoite lysates. The use of a fixative for reproducible coating is not required. The SPZ-ELISA was first validated using monoclonal antibodies specific for CSP and TRAP and then used for the characterization of immune sera from radiation attenuated sporozoite vaccinees. CONCLUSION: Applying this simple and highly reproducible approach to assess immune responses induced by malaria vaccines, both recombinant and whole parasite vaccines, (1) will help in the evaluation of immune responses induced by antigenically complex malaria vaccines such as the irradiated SPZ-vaccine, (2) will facilitate and accelerate the identification of immune correlates of protection, and (3) can also be a valuable assessment tool for antigen discovery as well as down-selection of vaccine formulations and, thereby, guide vaccine design. PMID- 29187200 TI - ApoA-I/A-II-HDL positively associates with apoB-lipoproteins as a potential atherogenic indicator. AB - BACKGROUND: We recently reported distinct nature of high-density lipoproteins (HDL) subgroup particles with apolipoprotein (apo) A-I but not apoA-II (LpAI) and HDL having both (LpAI:AII) based on the data from 314 Japanese. While plasma HDL level almost exclusively depends on concentration of LpAI having 3 to 4 apoA-I molecules, LpAI:AII appeared with almost constant concentration regardless of plasma HDL levels having stable structure with two apoA-I and one disulfide dimeric apoA-II molecules (Sci. Rep. 6; 31,532, 2016). The aim of this study is further characterization of LpAI:AII with respect to its role in atherogenesis. METHODS: Association of LpAI, LpAI:AII and other HDL parameters with apoB lipoprotein parameters was analyzed among the cohort data above. RESULTS: ApoA-I in LpAI negatively correlated with the apoB-lipoprotein parameters such as apoB, triglyceride, nonHDL-cholesterol, and nonHDL-cholesterol + triglyceride, which are apparently reflected in the relations of the total HDL parameters to apoB lipoproteins. In contrast, apoA-I in LpAI:AII and apoA-II positively correlated to the apoB-lipoprotein parameters even within their small range of variation. These relationships are independent of sex, but may slightly be influenced by the activity-related CETP mutations. CONCLUSIONS: The study suggested that LpAI:AII is an atherogenic indicator rather than antiatherogenic. These sub-fractions of HDL are to be evaluated separately for estimating atherogenic risk of the patients. PMID- 29187201 TI - Sirt1 interaction with active Smad2 modulates transforming growth factor-beta regulated transcription. AB - BACKGROUND: The simplicity of Transforming Growth Factor beta (TGFbeta) signaling pathway, linear and non-amplified, hardly sustains its variety of responses. This is often justified by the complex regulation showed by Smad proteins, TGFbeta signaling intracellular transducers, object of post-translational modifications that modulate TGFbeta-dependent transcription. Protein acetylation is emerging as a compelling mechanism affecting the activities of significant transcription factors, including p53, FOXO or NF-kB. Smad proteins might be controlled by this mechanism, implying that accessory factors capable of altering Smads transcriptional complexes acetylation status and hence regulate TGFbeta responses remain to be identified. Understanding this interaction may help in the assessment of TGFbeta signaling outcomes, extending from healthy physiology to pathological conditions and cancer. METHODS: A two-hybrid chimera interacting system allowed to identify Sirt1, a NAD+ dependent type III histone deacetylase, as a novel Smad2 interactor. Several well stablished cellular models were applied to characterize this interaction by means of co-immunoprecipitation of tagged proteins and immuno-fluorescence staining. The occurrence of the interaction at Smad2 driven transcriptomic complexes was studied by means of DNA-pull-down and chromatin immunoprecipitation (ChIP), while its effects were assessed by protein over-expression and siRNA applied into a TGFbeta-dependent reporter gene assay. RESULTS: The interaction was confirmed and observed to be enhanced upon Smad2 acetylation, a known feature of active and nuclear Smad2. However, Sirt1 did not play a major role in Smad2 deacetylation. Anti-Sirt1 ChIP showed increased recovery of promoter regions corresponding to Smad2-driven genes after TGFbeta stimulation, while its occurrence at Smad2-dependent transcriptomic complexes on DNA was found to effectively modulate gene expression. CONCLUSIONS: Sirt1 presence on Smad2-driven TGFbeta-dependent regulatory elements was detected and found to increase after TGFbeta treatment. Moreover, Sirt1 overexpression resulted in a decrease of the activity of a Smad2-driven TGFbeta-dependent reporter gene, while Sirt1 interference increased its activity. This would confirm the relevance of the discovered Sirt1-Smad2 interaction for the regulation of TGFbeta-dependent gene transcription.

AB - BACKGROUND: Optimization of the immunoglobulin (Ig) yield in bovine milk used as therapeutic immune milk or whey for the prevention of Clostridium difficile associated diarrhea in humans is of great importance to improve the economic efficiency of production. Individual dairy cows have diverse immune responses upon vaccination, resulting in a variable Ig yield in blood and milk. Therefore, it is advisable to pre-select cows with the best ability to produce and secrete high yields of specific Igs. RESULTS: The gene expression profile of pbMEC (primary bovine mammary epithelial cells), challenged with the gram-positive, non mastitis, pathogen Clostridium difficile showed distinct and significant differences in the gene expression of effector molecules of the innate immune system. A number of genes were identified that could possibly serve as molecular biomarkers to differentiate high responder cows from low responder cows. These identified genes play key roles in the promotion of innate immunity. CONCLUSION: Using a gene expression profiling approach, we showed that upon others, especially the gene expression of the pro-inflammatory cytokines was altered between the high and low responder cows. Those genes are indicated as potential molecular biomarkers in the pre-selection of cows that are able to secrete high immunoglobulin yields in milk. PMID- 29187203 TI - SoftHand at the CYBATHLON: a user's experience. AB - BACKGROUND: Roughly one-quarter of upper limb prosthesis users reject their prosthesis. Reasons for rejection range from comfort, to cost, aesthetics, function, and more. This paper follows a single user from training with and testing of a novel upper-limb myoelectric prosthesis (the SoftHand Pro) for participation in the CYBATHLON rehearsal to training for and competing in the CYBATHLON 2016 with a figure-of-nine harness controlled powered prosthesis (SoftHand Pro-H) to explore the feasibility and usability of a flexible anthropomorphic prosthetic hand. METHODS: The CYBATHLON pilot took part in multiple in-lab training sessions with the SoftHand Pro and SoftHand Pro-H; these sessions focused on basic control and use of the prosthetic devices and direct training of the tasks in the CYBATHLON. He used these devices in competition in the Powered Arm Prosthesis Race in the CYBATHLON rehearsal and 2016 events. RESULTS: In training for the CYBATHLON rehearsal, the subject was able to quickly improve performance with the myoelectric SHP despite typically using a body powered prosthetic hook. The subject improved further with additional training using the figure-of-nine harness-controlled SHPH in preparation for the CYBATHLON. The Pilot placed 3rd (out of 4) in the rehearsal. In the CYBATHLON, he placed 5th (out of 12) and was one of only two pilots who successfully completed all tasks in the competition, having the second-highest score overall. CONCLUSIONS: Results with the SoftHand Pro and Pro-H suggest it to be a viable alternative to existing anthropomorphic hands and show that the unique flexibility of the hand is easily learned and exploited. PMID- 29187205 TI - Combined double chambered right ventricle, tricuspid valve dysplasia, ventricular septal defect, and subaortic stenosis in a dog. AB - BACKGROUND: Double chambered right ventricle (DCRV) is a congenital heart anomaly where the right ventricle is divided into two chambers. We describe, for the first time, an unusual combination of DCRV combined with some other congenital heart defects. CASE PRESENTATION: A 1.2-year-old Golden Retriever was presented with lethargy, exercise intolerance and ascites. Physical examination revealed an irregularly irregular pulse and a grade V/VI, systolic, right cranial murmur. Electrocardiography revealed widened and splintered QRS complexes with a right bundle-branch block pattern. Radiography demonstrated right-sided cardiomegaly. Two-dimensional echocardiography identified a DCRV with tricuspid valve dysplasia. The patient died despite abdominocentesis and 4 days of oral pharmacotherapy, and necropsy revealed an anomalous fibromuscular structure that divided the right ventricle into two compartments. Another finding was tricuspid valve dysplasia with hypoplasia of the posterior and septal leaflets. The anterior leaflet was prominent, being part of the anomalous structure that divided the right ventricle. Necropsy also identified a perimembranous ventricular septal defect and mild subaortic stenosis. Histopathological examination of the fibromuscular band that separated the right ventricle identified longitudinally oriented layers of dense fibrous connective tissue and myocardial cells arranged in a plexiform pattern. The muscular component was well represented at the ventral area of the fibromuscular band, and was absent in the central zone. Superficially, the endocardium presented areas of nodular hyperplasia covering mainly the fibrous part of the abnormal structure. The nodules were sharply demarcated and were composed by loosely arranged connective tissue with myxoid appearance, covered by discrete hyperplastic endocardium. CONCLUSIONS: Concomitant cardiac malformations involving DCRV, tricuspid valve dysplasia, perimembranous ventricular septal defect and mild subaortic stenosis have not been previously described in veterinary medicine, and are reported here for the first time. Moreover, this is the first report of a canine patient with tricuspid valve dysplasia (TVD) and DCRV where the anterior leaflet is part of an anomalous structure dividing the right ventricle (RV) into two separate compartments. PMID- 29187206 TI - Multi-modality imaging evaluation of recurrent Tako-tsubo syndrome in a patient with coronary artery fibromuscular dysplasia. AB - BACKGROUND: Integrated bedside and sophisticated cardiac imaging techniques help characterize the discrepancy between myocardial injury and mechanic dysfunction in acute myocardial infarction. CASE PRESENTATION: A 57 year-old woman presented with sudden onset chest pain and ventricular fibrillation after hearing of her brother's death. The electrocardiography indicated "anterior wall ST segment elevation myocardial infarction". Coronary angiography ruled out obstructive lesion in the major coronary arteries, but revealed fibromuscular dysplasia of the distal left anterior descending artery. The ventriculography showed remarkable ventricular dilation, which affected much broader myocardium than the culprit vessel supplied. In a subsequent cardiac magnetic resonance study, delayed contrast (gadolinium) image revealed a focal left ventricular (LV) apical infarction. Her LV systolic function normalized within 1 week, except for a residual apical hypokinesis. She developed recurrent chest pain and LV dilation when she was laid off 9 months later. After supportive therapy, her symptoms improved and LV dysfunction normalized again. CONCLUSIONS: "Tako-tsubo" syndrome can occur recurrently in the heart with pre-existing localized myocardial infarction. Its molecular mechanism and clinical significance warrants further investigation. PMID- 29187204 TI - Experimental design and quantitative analysis of microbial community multiomics. AB - Studies of the microbiome have become increasingly sophisticated, and multiple sequence-based, molecular methods as well as culture-based methods exist for population-scale microbiome profiles. To link the resulting host and microbial data types to human health, several experimental design considerations, data analysis challenges, and statistical epidemiological approaches must be addressed. Here, we survey current best practices for experimental design in microbiome molecular epidemiology, including technologies for generating, analyzing, and integrating microbiome multiomics data. We highlight studies that have identified molecular bioactives that influence human health, and we suggest steps for scaling translational microbiome research to high-throughput target discovery across large populations. PMID- 29187207 TI - Metabolomic effects of CeO2, SiO2 and CuO metal oxide nanomaterials on HepG2 cells. AB - BACKGROUND: To better assess potential hepatotoxicity of nanomaterials, human liver HepG2 cells were exposed for 3 days to five different CeO2 (either 30 or 100 MUg/ml), 3 SiO2 based (30 MUg/ml) or 1 CuO (3 MUg/ml) nanomaterials with dry primary particle sizes ranging from 15 to 213 nm. Metabolomic assessment of exposed cells was then performed using four mass spectroscopy dependent platforms (LC and GC), finding 344 biochemicals. RESULTS: Four CeO2, 1 SiO2 and 1 CuO nanomaterials increased hepatocyte concentrations of many lipids, particularly free fatty acids and monoacylglycerols but only CuO elevated lysolipids and sphingolipids. In respect to structure-activity, we now know that five out of six tested CeO2, and both SiO2 and CuO, but zero out of four TiO2 nanomaterials have caused this elevated lipids effect in HepG2 cells. Observed decreases in UDP glucuronate (by CeO2) and S-adenosylmethionine (by CeO2 and CuO) and increased S adenosylhomocysteine (by CuO and some CeO2) suggest that a nanomaterial exposure increases transmethylation reactions and depletes hepatic methylation and glucuronidation capacity. Our metabolomics data suggests increased free radical attack on nucleotides. There was a clear pattern of nanomaterial-induced decreased nucleotide concentrations coupled with increased concentrations of nucleic acid degradation products. Purine and pyrimidine alterations included concentration increases for hypoxanthine, xanthine, allantoin, urate, inosine, adenosine 3',5'-diphosphate, cytidine and thymidine while decreases were seen for uridine 5'-diphosphate, UDP-glucuronate, uridine 5'-monophosphate, adenosine 5' diphosphate, adenosine 5'-monophophate, cytidine 5'-monophosphate and cytidine 3' monophosphate. Observed depletions of both 6-phosphogluconate, NADPH and NADH (all by CeO2) suggest that the HepG2 cells may be deficient in reducing equivalents and thus in a state of oxidative stress. CONCLUSIONS: Metal oxide nanomaterial exposure may compromise the methylation, glucuronidation and reduced glutathione conjugation systems; thus Phase II conjugational capacity of hepatocytes may be decreased. This metabolomics study of the effects of nine different nanomaterials has not only confirmed some observations of the prior 2014 study (lipid elevations caused by one CeO2 nanomaterial) but also found some entirely new effects (both SiO2 and CuO nanomaterials also increased the concentrations of several lipid classes, nanomaterial induced decreases in S adenosylmethionine, UDP-glucuronate, dipeptides, 6-phosphogluconate, NADPH and NADH). PMID- 29187208 TI - Multiple markers, niche modelling, and bioregions analyses to evaluate the genetic diversity of a plant species complex. AB - BACKGROUND: The classification of closely related plants is not straightforward. These morphologically similar taxa frequently maintain their inter-hybridization potential and share ancestral polymorphisms as a consequence of their recent divergence. Under the biological species concept, they may thus not be considered separate species. The Petunia integrifolia complex is especially interesting because, in addition to the features mentioned above, its taxa share a pollinator, and their geographical ranges show multiple overlaps. Here, we combined plastid genome sequences, nuclear microsatellites, AFLP markers, ecological niche modelling, and bioregions analysis to investigate the genetic variability between the different taxa of the P. integrifolia complex in a comprehensive sample covering the entire geographical range of the complex. RESULTS: Results from molecular markers did not fully align with the current taxonomic classification. Niche modelling and bioregions analyses revealed that taxa were associated with different ecological constraints, indicating that the habitat plays an important role in preserving species boundaries. For three taxa, our analyses showed a mostly conserved, non-overlapping geographical distribution over time. However, for two taxa, niche modelling found an overlapping distribution over time; these taxa were also associated with the same bioregions. CONCLUSIONS: cpDNA markers were better able to discriminate between Petunia taxa than SSRs and AFLPs. Overall, our results suggest that the P. integrifolia complex represents a continuum of individuals from distant and historically isolated populations, which share some morphological traits, but are established in four different evolutionary lineages. PMID- 29187209 TI - Biodistribution of single and aggregated gold nanoparticles exposed to the human lung epithelial tissue barrier at the air-liquid interface. AB - BACKGROUND: The lung represents the primary entry route for airborne particles into the human body. Most studies addressed possible adverse effects using single (nano)particles, but aerosolic nanoparticles (NPs) tend to aggregate and form structures of several hundreds nm in diameter, changing the physico-chemical properties and interaction with cells. Our aim was to investigate how aggregation might affect the biodistribution; cellular uptake and translocation over time of aerosolized NPs at the air-blood barrier interface using a multicellular lung system. RESULTS: Model gold nanoparticles (AuNPs) were engineered and well characterized to compare single NPs with aggregated NPs with hydrodynamic diameter of 32 and 106 nm, respectively. Exposures were performed by aerosolization of the particles onto the air-liquid interface of a three dimensional (3D) lung model. Particle deposition, cellular uptake and translocation kinetics of single and aggregated AuNPs were determined for various concentrations, (30, 60, 150 and 300 ng/cm2) and time points (4, 24 and 48 h) using transmission electron microscopy and inductively coupled plasma optical emission spectroscopy. No apparent harmful effect for single and aggregated AuNPs was observed by lactate dehydrogenase assay, nor pro-inflammation response by tumor necrosis factor alpha assessment. The cell layer integrity was also not impaired. The bio-distribution revealed that majority of the AuNPs, single or aggregated, were inside the cells, and only a minor fraction, less than 5%, was found on the basolateral side. No significant difference was observed in the translocation rate. However, aggregated AuNPs showed a significantly faster cellular uptake than single AuNPs at the first time point, i.e. 4 h. CONCLUSIONS: Our studies revealed that aggregated AuNPs showed significantly faster cellular uptake than single AuNPs at the first time point, i.e. 4 h, but the uptake rate was similar at later time points. In addition, aggregation did not affect translocation rate across the lung barrier model since similar translocation rates were observed for single as well as aggregated AuNPs. PMID- 29187210 TI - State of newborn care in South Sudan's displacement camps: a descriptive study of facility-based deliveries. AB - BACKGROUND: Approximately 2.7 million neonatal deaths occur annually, with highest rates of neonatal mortality in countries that have recently experienced conflict. Constant instability in South Sudan further strains a weakened health system and poses public health challenges during the neonatal period. We aimed to describe the state of newborn facility-level care in displaced person camps across Juba, Malakal, and Maban. METHODS: We conducted clinical observations of the labor and delivery period, exit interviews with recently delivered mothers, health facility assessments, and direct observations of midwife time-use. Study participants were mother-newborn pairs who sought services and birth attendants who provided delivery services between April and June 2016 in five health facilities. RESULTS: Facilities were found to be lacking the recommended medical supplies for essential newborn care. Two of the five facilities had skilled midwives working during all operating hours, with 6.2% of their time spent on postnatal care. Selected components of thermal care (62.5%), infection prevention (74.8%), and feeding support (63.6%) were commonly practiced, but postnatal monitoring (27.7%) was less consistently observed. Differences were found when comparing the primary care level to the hospital (thermal: relative risk [RR] 0.48 [95% CI] 0.40-0.58; infection: RR 1.28 [1.11-1.47]; feeding: RR 0.49 [0.40 0.58]; postnatal: RR 3.17 [2.01-5.00]). In the primary care level, relative to newborns delivered by traditional birth attendants, those delivered by skilled attendants were more likely to receive postnatal monitoring (RR 1.59 [1.09 2.32]), but other practices were not statistically different. Mothers' knowledge of danger signs was poor, with fever as the highest reported (44.8%) followed by not feeding well (41.0%), difficulty breathing (28.9%), reduced activity (27.7%), feeling cold (18.0%) and convulsions (11.2%). CONCLUSIONS: Addressing health service delivery in contexts affected by conflict is vital to reducing the global newborn mortality rate and reaching the Sustainable Development Goals. Gaps in intrapartum and postnatal care, particularly skilled care at birth, suggest a critical need to build the capacity of the existing health workforce while increasing access to skilled deliveries. PMID- 29187211 TI - Roles of KAI1 and nm23 in lymphangiogenesis and lymph metastasis of laryngeal squamous cell carcinoma. AB - BACKGROUND: Lymphatic metastasis contributes to the poor prognosis of laryngeal squamous cell carcinoma (LSCC). This study aimed to investigate the roles of two metastasis suppressor genes, KAI1 and nm23, in lymphangiogenesis and lymph metastasis of LSCC. METHODS: A total of 45 LSCC patients were enrolled in this study. The positive expression rates of KAI1 and nm23 protein were detected via immunohistochemistry in 45 LSCC and 22 normal laryngeal mucosa adjacent to LSCC. Micro-lymphatic vessel density (MLVD) was detected via immunohistochemistry with the specific antibody D2-40. Associations between KAI1 and nm23 expression and clinical characteristics of LSCC were then evaluated. RESULTS: The positive expression rates of KAI1 and nm23 were significantly lower in LSCC than normal laryngeal mucosa (P < 0.05). Significantly lower positive rates of KAI1 and nm23 were found in LSCC with lymphatic metastasis than those without lymphatic metastasis (P < 0.05), whereas MLVD was negatively correlated with the expression of KAI1 and nm23 (P < 0.05). However, no significant associations were found between KAI1 and nm23 expression and clinical characteristics of LSCC (sex, age, disease position, differentiation, and T-stage). CONCLUSIONS: Both KAI1 and nm23 can inhibit lymphangiogenesis and lymphatic metastasis in LSCC. PMID- 29187212 TI - Roles of Bronchopulmonary C-fibers in airway Hyperresponsiveness and airway remodeling induced by house dust mite. AB - BACKGROUND: Asthma is characterized by chronic airway inflammation, airway hyperresponsiveness (AHR), and airway remodeling. While exposure of house dust mites (HDM) is a common cause of asthma, the pathogenesis of the HDM-induced asthma is not fully understood. Bronchopulmonary C-fibers (PCFs) contribute to the neurogenic inflammation, viral infection induced-persistent AHR, and ovalbumin induced collagen deposition largely via releasing neuropeptides, such as substance P (SP). However, PCF roles in the pathogenesis of the HDM-induced asthma remain unexplored. The goal of this study was to determine what role PCFs played in generating these characteristics. METHODS: We compared the following variables among the PCF-intact and -degenerated BALB/c mice with and without chronic HDM exposure (four groups): 1) AHR and pulmonary SP; 2) airway smooth muscle (ASM) mass; 3) pulmonary inflammatory cells; and 4) epithelium thickening and mucus secretion. RESULTS: We found that HDM evoked AHR associated with upregulation of pulmonary SP and inflammation, ASM mass increase, epithelium thickenings, and mucus hypersecretion. PCF degeneration decreased the HDM-induced changes in AHR, pulmonary SP and inflammation, and ASM mass, but failed to significantly affect the epithelium thickening and mucus hypersecretion. CONCLUSION: Our data suggest an involvement of PCFs in the mechanisms by which HDM induces allergic asthma via airway inflammation, AHR, and airway remodeling. PMID- 29187213 TI - JMJD6 promotes melanoma carcinogenesis through regulation of the alternative splicing of PAK1, a key MAPK signaling component. AB - BACKGROUND: Melanoma, originated from melanocytes located on the basal membrane of the epithelial tissue, is the most aggressive form of skin cancer that accounts for 75% of skin cancer-related death. Although it is believed that BRAF mutation and the mitogen-activated protein kinase (MAPK) pathway play critical roles in the pathogenesis of melanoma, how the MAPK signaling is regulated in melanoma carcinogenesis is still not fully understood. METHODS: We characterized JMJD6 expression in melanoma tissue array by immunohistochemistry analysis. We used human melanoma A375, 451Lu and SK-MEL-1 cell lines for in vitro proliferation and invasion experiments, and xenograft transplanted mice using murine melanoma B16F10 cells by bioluminescence imaging for in vivo tumor growth and pulmonary metastasis assessments. Endothelial tube formation assay, chicken yolk sac membrane assay and matrigel plug assay were performed to test the effect of JMJD6 on the angiogenic potential in vitro and in vivo. RESULTS: Here we report that the jumonji C domain-containing demethylase/hydroxylase JMJD6 is markedly up-regulated in melanoma. We found that high expression of JMJD6 is closely correlated with advanced clinicopathologic stage, aggressiveness, and poor prognosis of melanoma. RNA-seq showed that knockdown of JMJD6 affects the alternative splicing of a panel of transcripts including that encoding for PAK1, a key component in MAPK signaling pathway. We demonstrated that JMJD6 enhances the MAPK signaling and promotes multiple cellular processes including melanogenesis, proliferation, invasion, and angiogenesis in melanoma cells. Interestingly, JMJD6 is transcriptionally activated by c-Jun, generating a feedforward loop to drive the development and progression of melanoma. CONCLUSIONS: Our results indicate that JMJD6 is critically involved in melanoma carcinogenesis, supporting the pursuit of JMJD6 as a potential biomarker for melanoma aggressiveness and a target for melanoma intervention. PMID- 29187214 TI - Synthetic enhancer design by in silico compensatory evolution reveals flexibility and constraint in cis-regulation. AB - BACKGROUND: Models that incorporate specific chemical mechanisms have been successful in describing the activity of Drosophila developmental enhancers as a function of underlying transcription factor binding motifs. Despite this, the minimum set of mechanisms required to reconstruct an enhancer from its constituent parts is not known. Synthetic biology offers the potential to test the sufficiency of known mechanisms to describe the activity of enhancers, as well as to uncover constraints on the number, order, and spacing of motifs. RESULTS: Using a functional model and in silico compensatory evolution, we generated putative synthetic even-skipped stripe 2 enhancers with varying degrees of similarity to the natural enhancer. These elements represent the evolutionary trajectories of the natural stripe 2 enhancer towards two synthetic enhancers designed ab initio. In the first trajectory, spatially regulated expression was maintained, even after more than a third of binding sites were lost. In the second, sequences with high similarity to the natural element did not drive expression, but a highly diverged sequence about half the length of the minimal stripe 2 enhancer drove ten times greater expression. Additionally, homotypic clusters of Zelda or Stat92E motifs, but not Bicoid, drove expression in developing embryos. CONCLUSIONS: Here, we present a functional model of gene regulation to test the degree to which the known transcription factors and their interactions explain the activity of the Drosophila even-skipped stripe 2 enhancer. Initial success in the first trajectory showed that the gene regulation model explains much of the function of the stripe 2 enhancer. Cases where expression deviated from prediction indicates that undescribed factors likely act to modulate expression. We also showed that activation driven Bicoid and Hunchback is highly sensitive to spatial organization of binding motifs. In contrast, Zelda and Stat92E drive expression from simple homotypic clusters, suggesting that activation driven by these factors is less constrained. Collectively, the 40 sequences generated in this work provides a powerful training set for building future models of gene regulation. PMID- 29187216 TI - Use of a flowable haemostat versus an oxidised regenerated cellulose agent in primary elective cardiac surgery: economic impact from a UK healthcare perspective. AB - BACKGROUND: Flowable haemostatic agents have been shown to be superior to non flowable agents in terms of haemostatic control and need for transfusion products in patients undergoing cardiac surgery. We investigated the economic impact of the use of a flowable haemostatic agent (Floseal) compared with non-flowable oxidised regenerated cellulose (ORC) agent in primary elective cardiac surgery from the perspective of the UK National Health Service (NHS). METHODS: A cost consequence framework based upon clinical data from a prospective trial and an observational trial and NHS-specific actual reference costs (2016) was developed to compare the economic impact of Floseal with that of ORC. The individual domains of care investigated comprised complications (major and minor) avoided, operating room time savings, surgical revisions for bleeding avoided and transfusions avoided. The cost impact of Floseal versus ORC on ICU days and extended bed days avoided was modelled separately. RESULTS: Compared with ORC, the use of Floseal would be associated with overall net savings to the NHS of L178,283 per 100 cardiac surgery patients who experience intraoperative bleeding requiring haemostatic therapy. Cost savings were apparent in all individual domains of care (complications avoided: L83,536; operating room time saved: L63,969; surgical revisions avoided: L34,038; and blood transfusions avoided: L22,317). Cost savings per 100 patients with Floseal over ORC in terms of ICU days avoided (n = 30) and extended bed days avoided (n = 51.7) were L57,960 and L21,965, respectively. A sensitivity analysis indicated that these findings remained robust when the model parameters representing the clinical benefit of Floseal over ORC were reduced by up to 20%. CONCLUSIONS: Despite higher initial acquisition costs, the use of flowable haemostatic agents achieves substantial cost savings over non-flowable agents in cardiac surgery. These cost savings commence during the operating theatre and appear to continue to be realised throughout the postoperative period. PMID- 29187215 TI - Criteria for identifying the molecular basis of the engram (CaMKII, PKMzeta). AB - The engram refers to the molecular changes by which a memory is stored in the brain. Substantial evidence suggests that memory involves learning-dependent changes at synapses, a process termed long-term potentiation (LTP). Thus, understanding the storages process that underlies LTP may provide insight into how the engram is stored. LTP involves induction, maintenance (storage), and expression sub-processes; special tests are required to specifically reveal properties of the storage process. The strongest of these is the Erasure test in which a transiently applied agent that attacks a putative storage molecule may lead to persistent erasure of previously induced LTP/memory. Two major hypotheses have been proposed for LTP/memory storage: the CaMKII and PKM-zeta hypotheses. After discussing the tests that can be used to identify the engram (Necessity test, Saturation/Occlusion test, Erasure test), the status of these hypotheses is evaluated, based on the literature on LTP and memory-guided behavior. Review of the literature indicates that all three tests noted above support the CaMKII hypothesis when done at both the LTP level and at the behavioral level. Taken together, the results strongly suggest that the engram is stored by an LTP process in which CaMKII is a critical memory storage molecule. PMID- 29187218 TI - Open stent graft repair with upper-half Sternotomy for blunt thoracic aortic injury: a case report. AB - BACKGROUND: Thoracic endovascular aortic repair is now widely applied to the treatment of blunt aortic injury. However, its long-term outcomes remain unclear. Endoleakage and migration might occur in the long term, especially when younger patients undergo endovascular aortic repair. In open stent grafting, the proximal end of the open stent graft is directly sutured to the native aorta, which may reduce the risk of endoleakage and migration. We applied open stent grafting to the treatment of blunt aortic injury in the subacute phase and herein report the patient's clinical course. CASE PRESENTATION: A 20-year-old man with a developmental disorder collided with a steel tower while skiing. He was transferred to our hospital by helicopter. X-ray examination and computed tomography revealed fractures of left humeral head and femoral neck and aortic isthmus dissection. We did not perform an acute-phase operation because of the presence of multiple trauma and instead performed open stent grafting with an upper-half sternotomy 42 days after the injury. He recovered uneventfully without psychological problems other than his preexisting developmental disorder. No endoleakage or aneurysm was observed during an 18-month follow-up period. CONCLUSIONS: Open stent grafting might be an alternative to open surgery and thoracic endovascular aortic repair for blunt chest trauma, although intensive follow-up is needed. PMID- 29187217 TI - The effects of care bundles on patient outcomes: a systematic review and meta analysis. AB - BACKGROUND: Care bundles are a set of three to five evidence-informed practices performed collectively and reliably to improve the quality of care. Care bundles are used widely across healthcare settings with the aim of preventing and managing different health conditions. This is the first systematic review designed to determine the effects of care bundles on patient outcomes and the behaviour of healthcare workers in relation to fidelity with care bundles. METHODS: This systematic review is reported in line with the PRISMA statement for reporting systematic reviews and meta-analyses. A total of 5796 abstracts were retrieved through a systematic search for articles published between January 1, 2001, to February 4, 2017, in the Cochrane Central Register for Controlled Trials, MEDLINE, EMBASE, British Nursing Index, CINAHL, PsychInfo, British Library, Conference Proceeding Citation Index, OpenGrey trials (including cluster randomised trials) and non-randomised studies (comprising controlled before-after studies, interrupted time series, cohort studies) of care bundles for any health condition and any healthcare settings were considered. Following the removal of duplicated studies, two reviewers independently screen 3134 records. Three authors performed data extraction independently. We compared the care bundles with usual care to evaluate the effects of care bundles on the risk of negative patient outcomes. Random-effect models were used to further explore the effects of subgroups. RESULTS: In total, 37 studies (6 randomised trials, 31 controlled before-after studies) were eligible for inclusion. The effect of care bundles on patient outcomes is uncertain. For randomised trial data, the pooled relative risk of negative effects between care bundle and control groups was 0.97 [95% CI 0.71 to 1.34; 2049 participants]. The relative risk of negative patient outcomes from controlled before-after studies favoured the care bundle treated groups (0.66 [95% CI 0.59 to 0.75; 119,178 participants]). However, using GRADE, we assessed the certainty of all of the evidence to be very low (downgraded for risk of bias, inconsistency, indirectness). CONCLUSIONS: Very low quality evidence from controlled before-after studies suggests that care bundles may reduce the risk of negative outcomes when compared with usual care. By contrast, the better quality evidence from six randomised trials is more uncertain. TRIAL REGISTRATION: PROSPERO, CRD42016033175. PMID- 29187219 TI - Re-irradiation for recurrent glioma- the NCI experience in tumor control, OAR toxicity and proposal of a novel prognostic scoring system. AB - PURPOSE/OBJECTIVES: Despite mounting evidence for the use of re-irradiation (re RT) in recurrent high grade glioma, optimal patient selection criteria for re-RT remain unknown. We present a novel scoring system based on radiobiology principles including target independent factors, the likelihood of target control, and the anticipated organ at risk (OAR) toxicity to allow for proper patient selection in the setting of recurrent glioma. MATERIALS/METHODS: Thirty one patients with recurrent glioma who received re-RT (2008-2016) at NCI - NIH were included in the analysis. A novel scoring system for overall survival (OS) and progression free survival (PFS) was designed to include:1) target independent factors (age, KPS (Karnofsky Performance Status), histology, presence of symptoms), 2) target control, and 3) OAR toxicity risk. Normal tissue complication probability (NTCP) calculations were performed using the Lyman model. Kaplan-Meier analysis was performed for overall survival (OS) and progression free survival (PFS) for comparison amongst variables. RESULTS: No patient, including those who received dose to OAR above the published tolerance dose, experienced any treatment related grade 3-5 toxicity with a median PFS and OS from re-RT of 4 months (0.5-103) and 6 months (0.7-103) respectively. Based on cumulative maximum doses the average NTCP was 25% (0-99%) for the chiasm, 21% (0 99%) for the right optic nerve, 6% (0-92%) for the left optic nerve, and 59% (0 100%) for the brainstem. The independent factor and target control scores were each statistically significant for OS and the combination of independent factors plus target control was also significant for both OS (p = 0.02) and PFS (p = 0.006). The anticipated toxicity risk score was not statistically significant. CONCLUSION: Our scoring system may represent a novel approach to patient selection for re-RT in recurrent high grade glioma. Further validation in larger patient cohorts including compilation of doses to tumor and OAR may help refine this further for inclusion into clinical trials and general practice. PMID- 29187220 TI - Genomic copy number variation analysis in multiple system atrophy. AB - Genomic variation includes single-nucleotide variants, small insertions or deletions (indels), and copy number variants (CNVs). CNVs affect gene expression by altering the genome structure and transposable elements within a region. CNVs are greater than 1 kb in size; hence, CNVs can produce more variation than can individual single-nucleotide variations that are detected by next-generation sequencing. Multiple system atrophy (MSA) is an alpha-synucleinopathy adult-onset disorder. Pathologically, it is characterized by insoluble aggregation of filamentous alpha-synuclein in brain oligodendrocytes. Generally, MSA is sporadic, although there are rare cases of familial MSA. In addition, the frequencies of the clinical phenotypes differ considerably among countries. Reports indicate that genetic factors play roles in the mechanisms involved in the pathology and onset of MSA. To evaluate the genetic background of this disorder, we attempted to determine whether there are differences in CNVs between patients with MSA and normal control subjects. We found that the number of CNVs on chromosomes 5, 22, and 4 was increased in MSA; 3 CNVs in non-coding regions were considered risk factors for MSA. Our results show that CNVs in non-coding regions influence the expression of genes through transcription-related mechanisms and potentially increase subsequent structural alterations of chromosomes. Therefore, these CNVs likely play roles in the molecular mechanisms underlying MSA.

AB - BACKGROUND: Plasmablastic lymphoma (PBL) is relatively new clinical entity described as a distinct subtype of diffuse large B-cell lymphoma (DLBCL). It is characterized by its aggressive nature and proliferation of large neoplastic cells resembling immunoblasts including cells with more obvious plasmacytic differentiation. In this case report, we describe an unexpected finding of PBL associated with a mature cystic teratoma of the ovary in a young immune competent woman. CASE PRESENTATION: A 19-year old woman was admitted to the hospital with generalized lymphadenopathy, a pelvic tumor mass measuring 35 * 30 cm and a 4 cm lump in her right breast. She underwent a right salpingo-oophorectomy, lymphadenectomy, splenectomy, omentectomy, and a right breast lumpectomy. On macroscopic examination the right ovary was replaced by a thick-walled multilocular cystic tumor. Upon incision, the cysts were filled with thick, greasy sebaceous material and hair and there were several solid nodules within the cyst walls. Histological examination revealed a mature cystic teratoma and malignant non-Hodgkin lymphoma (NHL) within the solid nodules. Tumor tissue from the right breast, spleen and lymph nodes, all had the same histological, NHL morphology. After extensive immunostaining, a diagnosis of PBL was made. Following surgery, the patient was treated with different chemotherapy regimens, without any significant regression of the disease, and died of multiple organ failure. CONCLUSIONS: Primary NHL of the ovary is relatively rare occurrence while secondary involvement by lymphoma is much more common. PBL is a rare lymphoma, primarily reported in the jaw and oral mucosa, but also documented in extra-oral sites. To the best of our knowledge, this is the first case described in a mature ovarian cystic teratoma. Although the patient was HIV-negative and immune competent, she had progressive disease and died despite aggressive chemotherapy 11 months after the initial diagnosis. PMID- 29187221 TI - Autophagy maintains the stemness of ovarian cancer stem cells by FOXA2. AB - BACKGROUND: Cancer stem cells (CSCs) are regarded as the main cell type responsible for the initiation, metastasis, drug resistance, and recurrence of cancer. But the mechanism by which cancer stem cells maintain their stemness remains unclear. METHODS AND RESULTS: In the present study, ovarian cancer stem cells (OCSCs) were revealed to have an enhanced autophagic flux. Furthermore, their chemoresistance and ability to self-renewal in vitro were decreased when autophagy was inhibited by Bafilomycin A1(BafA1), Chloroquine(CQ) or autophagy related 5(ATG5) knockdown. PCR array screening determined that Forkhead Box A2(FOXA2) was highly expressed in OCSCs, and correspondingly regulated by autophagy activity. In addition, the self-renewal ability was decreased in the case of FOXA2 knockdown by shRNA in OCSCs. Overexpression of FOXA2 from the pEGFP(+)-FOXA2 plasmid partially reversed the depressed self-renewal ability of OCSCs during autophagy inhibition. CONCLUSIONS: Our findings suggest that autophagy, through participation of FOXA2, maintains the characteristics of OCSCs. Autophagy and FOXA2 are therefore potential targets for ovarian cancer stem cell directed therapies. PMID- 29187224 TI - Correction to: FLAGS, frequently mutated genes in public exomes.

PMID- 29187225 TI - Robotic sleeve lobectomy with four arms for lung cancer centrally located in the right lower lobe: a case report. AB - Sleeve lobectomy can preserve healthy lung parenchyma in centrally located lung cancer surgery. Video-assisted thoracoscopic surgery (VATS) lobectomy has been shown to have better results for postoperative complications than thoracotomy lobectomy. However, its limitations in visualization of operative field and handling of instruments restrain surgeons performing sleeve lobectomy. Robotic surgery has several advantages, including magnified 3-dimensional vision and angulation of the robot arm that can provide better circumstances for sleeve lobectomy than VATS. However, robotic sleeve lobectomy has been rarely reported. Here, we describe our experience of performing robotic sleeve lobectomy using four arms for lung cancer centrally located in the right lower lobe. PMID- 29187226 TI - Development and pilot testing of an informed consent video for patients with limb trauma prior to debridement surgery using a modified Delphi technique. AB - BACKGROUND: Ensuring adequate informed consent for surgery in a trauma setting is challenging. We developed and pilot tested an educational video containing information regarding the informed consent process for surgery in trauma patients and a knowledge measure instrument and evaluated whether the audiovisual presentation improved the patients' knowledge regarding their procedure and aftercare and their satisfaction with the informed consent process. METHODS: A modified Delphi technique in which a panel of experts participated in successive rounds of shared scoring of items to forecast outcomes was applied to reach a consensus among the experts. The resulting consensus was used to develop the video content and questions for measuring the understanding of the informed consent for debridement surgery in limb trauma patients. The expert panel included experienced patients. The participants in this pilot study were enrolled as a convenience sample of adult trauma patients scheduled to receive surgery. RESULTS: The modified Delphi technique comprised three rounds over a 4-month period. The items given higher scores by the experts in several categories were chosen for the subsequent rounds until consensus was reached. The experts reached a consensus on each item after the three-round process. The final knowledge measure comprising 10 questions was developed and validated. Thirty eligible trauma patients presenting to the Emergency Department (ED) were approached and completed the questionnaires in this pilot study. The participants exhibited significantly higher mean knowledge and satisfaction scores after watching the educational video than before watching the video. CONCLUSIONS: Our process is promising for developing procedure-specific informed consent and audiovisual aids in medical and surgical specialties. The educational video was developed using a scientific method that integrated the opinions of different stakeholders, particularly patients. This video is a useful tool for improving the knowledge and satisfaction of trauma patients in the ED. The modified Delphi technique is an effective method for collecting experts' opinions and reaching a consensus on the content of educational materials for informed consent. Institutions should prioritize patient-centered health care and develop a structured informed consent process to improve the quality of care.

PMID- 29187227 TI - Obesity reversibly depletes the basal cell population and enhances mammary epithelial cell estrogen receptor alpha expression and progenitor activity. AB - BACKGROUND: Obesity is correlated with an increased risk for developing postmenopausal breast cancer. Since obesity rates continue to rise worldwide, it is important to understand how the obese microenvironment influences normal mammary tissue to increase breast cancer risk. We hypothesized that obesity increases the proportion of luminal progenitor cells, which are thought to be the cells of origin for the most common types of breast cancer, potentially leading to an increased risk for breast cancer. METHODS: To study the obese microenvironment within the mammary gland, we used a high-fat diet mouse model of obesity and human breast tissue from reduction mammoplasty surgery. We identified changes in breast epithelial cell populations using flow cytometry for cell surface markers, in vitro functional assays and expression of markers on breast tissue sections. RESULTS: In both obese female mice and women, mammary epithelial cell populations demonstrated significant decreases in basal/myoepithelial cells, using either flow cytometry or cell-type-specific markers (SMA and p63). Estrogen receptor alpha (ERalpha) expression was significantly increased in luminal cells in obese mammary tissue, compared with control mice or breast tissue from lean women. Functional assays demonstrated significantly enhanced mammary epithelial progenitor activity in obese mammary epithelial cells and elevated numbers of ERalpha-positive epithelial cells that were co-labeled with markers of proliferation. Weight loss in a group of obese mice reversed increases in progenitor activity and ERalpha expression observed in obese mammary tissue. CONCLUSIONS: Obesity enhances ERalpha-positive epithelial cells, reduces the number of basal/myoepithelial cells, and increases stem/progenitor activity within normal mammary tissue in both women and female mice. These changes in epithelial cell populations induced by obesity are reversible with weight loss. Our findings support further studies to examine how obesity-induced changes in stem/progenitor cells impact breast tumor incidence and histologic tumor types. PMID- 29187229 TI - Optimal RNA isolation method and primer design to detect gene knockdown by qPCR when validating Drosophila transgenic RNAi lines. AB - OBJECTIVE: RNA interference is employed extensively in Drosophila research to study gene function within a specific cell-type or tissue. Thousands of transgenic Drosophila lines have been generated to express double stranded RNA for gene knockdown; however, no standardized method exists for quantifying their knockdown efficiency. Since antibodies are not available for many proteins, quantitative real-time PCR is often used. Here, we explore how primer design and RNA isolation method can influence detection of gene knockdown using qPCR. RESULTS: We tested differences in detected gene knockdown efficiency when using purified polyadenylated mRNA or total RNA as templates for cDNA synthesis. We also tested two different primer locations for each gene: one to amplify a region 5' of the RNAi cut site, and one to amplify a region 3' of the cut site. Consistently, the strongest gene knockdown was detected when qPCR was performed using 5' primer sets in combination with mRNA-derived cDNA. Our results indicate that detection of undegraded mRNA cleavage fragments can result in underestimation of true knockdown efficiency for a RNAi construct. Purification of polyadenylated mRNA, combined with primers designed to amplify the non polyadenylated 5' mRNA cleavage fragment can avoid this problem. PMID- 29187230 TI - Decreasing Delirium through Music (DDM) in critically ill, mechanically ventilated patients in the intensive care unit: study protocol for a pilot randomized controlled trial. AB - BACKGROUND: Delirium is a highly prevalent and morbid syndrome in intensive care units (ICUs). Changing the stressful environment within the ICU via music may be an effective and a scalable way to reduce the burden of delirium. METHODS/DESIGN: The Decreasing Delirium through Music (DDM) study is a three-arm, single-blind, randomized controlled feasibility trial. Sixty patients admitted to the ICU with respiratory failure requiring mechanical ventilation will be randomized to one of three arms (20 participants per arm): (1) personalized music, (2) non personalized relaxing music, or (3) attention-control. Music preferences will be obtained from all enrolled participants or their family caregivers. Participants will receive two 1-h audio sessions a day through noise-cancelling headphones and mp3 players. Our primary aim is to determine the feasibility of the trial design (recruitment, adherence, participant retention, design and delivery of the music intervention). Our secondary aim is to estimate the potential effect size of patient-preferred music listening in reducing delirium, as measured by the Confusion Assessment Method for the ICU (CAM-ICU). Participants will receive twice daily assessments for level of sedation and presence of delirium. Enrolled participants will be followed in the hospital until death, discharge, or up to 28 days, and seen in the Critical Care Recovery Clinic at 90 days. DISCUSSION: DDM is a feasibility trial to provide personalized and non-personalized music interventions for critically ill, mechanically ventilated patients. Our trial will also estimate the preliminary efficacy of music interventions on reducing delirium incidence and severity. TRIAL REGISTRATION: ClinicalTrials.gov, Identifier: NCT03095443 . Registered on 23 March 2017. PMID- 29187231 TI - Post encephalitic parkinsonism following dengue viral infection. AB - BACKGROUND: Incidence of dengue fever as well as dengue hemorrhagic fever is increasing in Sri Lanka especially among elderly population. As the number of cases is rising, rare complications of dengue illness also can be seen in clinical practice when compared to the past few years. Prompt identification and treatment of such complications is challenging due to lack of awareness and unavailability of standard treatment. CASE PRESENTATION: 69 years old man presented with acute onset fever and was diagnosed as having dengue illness. On the 4th day of illness, the disease was progressed into dengue haemorrhagic fever and recovered uneventfully. Although he recovered from primary illness, his general condition continued to deteriorate due to new onset of features of parkinsonism. Cerebrospinal fluid analysis and electro encephalogram showed evidence of encephalitis. Cerebrospinal fluid analysis also revealed positive IgM antibodies against dengue virus. Then the diagnosis of post encephalitic parkinsonism following dengue viral infection was made and started on. He was started on SINEMET (carbidopa 10 mg and levodopa 100 mg) half tablet 6 hourly started. After 1 week of treatment he showed marked improvement and then patient was discharged with further follow up plan. CONCLUSION: Although the management of dengue illness and dengue haemorrhagic fever is straightforward, recognition and treatment of rare complications like post encephalitic parkinsonism following dengue viral infection is difficult without great clinical suspicion. PMID- 29187232 TI - Long-term continuous renal replacement therapy and anticoagulation with citrate in critically ill patients with severe liver dysfunction. AB - BACKGROUND: As of 2009, anticoagulation with citrate was standard practice in continuous renal replacement therapy (CRRT) for critically ill patients at the University Medical Centre of Saarland, Germany. Partial hepatic metabolism of citrate means accumulation may occur during CRRT in critically ill patients with impaired liver function. The aim of this study was to evaluate the actual influence of hepatic function on citrate-associated complications during long term CRRT. METHODS: In a retrospective study conducted between January 2009 and November 2012, all cases of dialysis therapy performed in the interdisciplinary surgical intensive care unit were analysed. Inclusion criteria were CRRT and regional anticoagulation with citrate, pronounced liver dysfunction, and pathologically reduced indocyanine green plasma disappearance rate (ICG-PDR). RESULTS: A total of 1339 CRRTs were performed in 69 critically ill patients with liver failure. At admission, the mean Model for End-stage Liver Disease score was 19.2, and the mean ICG-PDR was 9.8%. Eight patients were treated with liver replacement therapy, and 30 underwent transplants. The mortality rate was 40%. The mean duration of dialysis was 19.4 days, and the circuit patency was 62.2 h. Accumulation of citrate was detected indirectly by total serum calcium/ionised serum calcium (tCa/iCa) ratio > 2.4. This was noted in 16 patients (23.2%). Dialysis had not to be discontinued for metabolic disorder or accumulation of citrate in any case. In 26% of cases, metabolic alkalosis occurred with pH > 7.5. Interestingly, no correlation between citrate accumulation and liver function parameters was detected. Moreover, most standard laboratory liver function parameters showed poor predictive capabilities for accumulation of citrate. CONCLUSIONS: Our findings indicate that extra-hepatic metabolism of citrate seems to exist, avoiding in most cases citrate accumulation in critically ill patients despite impaired liver function. Because the citric acid cycle is oxygen dependent, disturbed microcirculation would result in inadequate citrate metabolism. Raising the tCa/iCa ratio would therefore be an indicator of severity of illness and mortality rather than of liver failure. However, further studies are warranted for confirmation. PMID- 29187234 TI - COGcollator: a web server for analysis of distant relationships between homologous protein families. AB - BACKGROUND: The Clusters of Orthologous Groups (COGs) of proteins systematize evolutionary related proteins into specific groups with similar functions. However, the available databases do not provide means to assess the extent of similarity between the COGs. AIM: We intended to provide a method for identification and visualization of evolutionary relationships between the COGs, as well as a respective web server. RESULTS: Here we introduce the COGcollator, a web tool for identification of evolutionarily related COGs and their further analysis. We demonstrate the utility of this tool by identifying the COGs that contain distant homologs of (i) the catalytic subunit of bacterial rotary membrane ATP synthases and (ii) the DNA/RNA helicases of the superfamily 1.

AB - BACKGROUND: Post-translational modifications (PTMs) constitute a huge group of chemical modifications increasing the complexity of the proteomes of living beings. PTMs have been discussed as potential anti-malarial drug targets due to their involvement in many cell processes. O-GlcNAcylation is a widespread PTM found in different organisms including Plasmodium falciparum. The aim of this study was to identify O-GlcNAcylated proteins of P. falciparum, to learn more about the modification process and to understand its eventual functions in the Apicomplexans. METHODS: The P. falciparum strain 3D7 was amplified in erythrocytes and purified. The proteome was checked for O-GlcNAcylation using different methods. The level of UDP-GlcNAc, the donor of the sugar moiety for O GlcNAcylation processes, was measured using high-pH anion exchange chromatography. O-GlcNAcylated proteins were enriched and purified utilizing either click chemistry labelling or adsorption on succinyl-wheat germ agglutinin beads. Proteins were then identified by mass-spectrometry (nano-LC MS/MS). RESULTS: While low when compared to MRC5 control cells, P. falciparum disposes of its own pool of UDP-GlcNAc. By using proteomics methods, 13 O-GlcNAcylated proteins were unambiguously identified (11 by click-chemistry and 6 by sWGA-beads enrichment; 4 being identified by the 2 approaches) in late trophozoites. These proteins are all part of pathways, functions and structures important for the parasite survival. By probing clicked-proteins with specific antibodies, Hsp70 and alpha-tubulin were identified as P. falciparum O-GlcNAc-bearing proteins. CONCLUSIONS: This study is the first report on the identity of P. falciparum O GlcNAcylated proteins. While the parasite O-GlcNAcome seems close to those of other species, the structural differences exhibited by the proteomes provides a glimpse of innovative therapeutic paths to fight malaria. Blocking biosynthesis of UDP-GlcNAc in the parasites is another promising option to reduce Plasmodium life cycle. PMID- 29187235 TI - Urine cell-free microRNA as biomarkers for transitional cell carcinoma. AB - OBJECTIVE: MicroRNA (miRNA) are short nucleotide strands with a regulatory function in the cell. Several miRNAs have been shown to be useful as biomarkers for different neoplasms. The aim of this project was to assess whether levels of miRNA in cell free urine could be used as a biomarker in transitional cell carcinoma (TCC). RESULTS: cDNA libraries were produced based on small RNAs in urine samples of fourteen TCC patients and twenty healthy volunteers. Resulting reads were deep sequenced on Illumina HiSeq sequencer with the intent of characterizing cell free urine miRNA profiles. A statistically significant difference was found for a single miRNA; miR-210 was > sixfold higher in the TCC group compared to the control group. Furthermore, we were able to produce a diagnostic score by summing of standardized levels of overexpressed miRNA. This score was considerably higher in TCC patients with a sensitivity of 0.93, specificity of 0.76 and negative predictive value > 0.97. PMID- 29187236 TI - Obstruction in the third portion of the duodenum due to a diospyrobezoar: a case report. AB - BACKGROUND: Duodenal obstruction occurs mainly due to physical lesions such as duodenal ulcers or tumors. Obstruction due to bezoars is rare. We describe an extremely rare case of obstruction in the third portion of the duodenum caused by a diospyrobezoar 15 months after laparoscopic distal gastrectomy for early gastric cancer. CASE PRESENTATION: A 73-year-old man who underwent laparoscopic distal gastrectomy for early gastric cancer 15 months before admission experienced abdominal distension and occasional vomiting. The symptoms worsened and ingestion became difficult; therefore, he was admitted to our department. Computed tomography (CT) performed on admission revealed a solid mass in the third portion of the duodenum and dilatation of the oral side of the duodenum and remnant stomach. Esophagogastroduodenoscopy (EGD) revealed a bezoar deep in the third portion of the duodenum. We could neither remove nor crush the bezoar. At midnight on the day of EGD, he experienced sudden abdominal pain. Repeat CT revealed that the bezoar had vanished from the duodenum and was observed in the ileum. Moreover, small bowel dilatation was observed on the oral side of the bezoar. Although CT showed neither free air nor ascites, laboratory data showed the increase of leukocyte (8400/MUL) and C-reactive protein (18.1 mg/dL), and abdominal pain was severe. Emergency surgery was performed because conservative treatment was considered ineffective. We tried advancing the bezoar into the colon, but the ileum was too narrow; therefore, we incised the ileum and removed the bezoar. The bezoar was ocher, elastic, and hard, and its cross-section was uniform and orange. The postsurgical interview revealed that the patient loved eating Japanese persimmons (Diospyros kaki); therefore, he was diagnosed with a diospyrobezoar. His postoperative progress was good and without complications. He left the hospital 10 days after surgery. EGD performed 4 weeks after surgery revealed no abnormal duodenal findings. CONCLUSIONS: We describe a rare case of obstruction in the third portion of the duodenum caused by a diospyrobezoar 15 months after laparoscopic distal gastrectomy with Billroth I reconstruction for early gastric cancer.

PMID- 29187237 TI - "It wasn't as bad as I thought it would be": a qualitative study of early stage non-small cell lung cancer patients after treatment. AB - OBJECTIVE: While surgical resection is recommended for most patients with early stage lung cancer, stereotactic body radiotherapy (SBRT) is being increasingly utilized. Provider-patient communication regarding risks/benefits of each approach may be a modifiable factor leading to improved patient-centered outcomes. Our objective was to determine a framework and recommended strategies on how to best communicate with patients with early stage non-small cell lung cancer (NSCLC) in the post-treatment setting. We qualitatively evaluated the experiences of 11 patients with early clinical stage NSCLC after treatment, with a focus on treatment experience, knowledge obtained, communication, and recommendations. We used conventional content analysis and a patient-centered communication theoretical model to guide our understanding. RESULTS: Five patients received surgery and six received SBRT. Both treatments were generally well-tolerated. Few participants reported communication deficits around receiving follow-up information, although several had remaining questions about their treatment outcome (mainly those who underwent SBRT). They described feeling anxious regarding their first surveillance CT scan and clinician visit. Overall, participants remained satisfied with care because of implicit trust in their clinicians rather than explicit communication. Communication gaps remain but may be addressed by a trusting relationship with the clinician. Patients recommend clinicians give thorough explanations and personalize when possible. PMID- 29187239 TI - A model of population dynamics of TB in a prison system and application to South Africa. AB - BACKGROUND: Tuberculosis (TB) continues to spread in South African prisons in particular, as prisons are over-capacitated and have poor ventilation. The awaiting trial detainees are not screened on admission and are at high risk of getting infected with TB. RESULTS: We propose a compartmental model to describe the population dynamics of TB disease in prisons. Our model considers the inflow of susceptible, exposed and TB infectives into the prison population. Removal of individuals out of the prison population can be either by death or by being released from prison, as compared to a general population in which removal is only by death. We describe conditions, including non-inflow of infectives into the prison, which will ensure that TB can be eradicated from the prison population. The model is calibrated for the South African prison system, by using data in existing literature. The model can be used to make quantitative projections of TB prevalence and to measure the effect of interventions. Illustrative simulations in this regard are presented. The model can be used for other prison populations too, if data is available to calculate the model parameters. CONCLUSIONS: Various simulations generated with our model serve to illustrate how it can be utilized in making future projections of the levels of prevalence of TB, and to quantify the effect of interventions such as screening, treatment or reduction of transmission parameter values through improved living conditions for inmates. This makes it particularly useful as there are various targets set by the World Health Organization and by governments, for reduction of TB prevalence and ultimately its eradication. Towards eradication of TB from a prison system, the theorem on global stability of the disease-free state is a useful indicator. PMID- 29187240 TI - Effect of genetic ancestry to the risk of susceptibility to gastric cancer in a mixed population of the Brazilian Amazon. AB - BACKGROUND: Global literature describes differences in the incidence of gastric cancer among populations. For instance, Europeans have lower incidence rates of gastric cancer in relation to Latin and Asian populations, particularly Korean and Japanese populations. However, only a few studies have been able to verify the occurrence of gastric cancer in admixed populations with high interethnic degree mix, such as the Brazilian Amazon region. RESULTS: We observed an increase in European ancestry in the control group compared to the case group (47% vs. 41%). Using increments of 10%, compared to categorical distribution of European ancestry in the sample, we found a difference in the contribution between cases and controls (p = 0.03). Multiple logistic regression was performed to determine the influence of European ancestry in susceptibility to gastric cancer in the sample. According to the adopted model, for each 10% increase in European ancestry, there is a 20% decrease chance of developing gastric cancer (P = 0.0121; OR = 0.81; 95% CI 0.54-0.83). CONCLUSION: Overall, the results suggest that a greater contribution of European ancestry can be a protective factor for the development of gastric cancer in the studied Amazon population. It can help to establish protocols able to predict susceptibility to gastric cancer in admixed populations. PMID- 29187241 TI - Profile of red blood cell morphologies and causes of anaemia among pregnant women at first clinic visit in the mount Cameroon area: a prospective cross sectional study. AB - OBJECTIVE: Anaemia is a serious problem in pregnancy in malaria-endemic countries. This study investigated red cell morphologies and possible causes of anaemia among pregnant women at first clinic visit. Venous blood samples from consented women were used to determine haemoglobin (Hb) levels, mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) using an automated haematology analyzer. Malaria parasitaemia was diagnosed by microscopy. Definitions were as follows: anaemia (Hb < 11.0 g/dl), microcytosis (MCV < 78 fl), macrocytosis (MCV > 101 fl), hypochromasia (MCH < 27 pg), microcytic hypochromia or normocytic hypochromia with anaemia [iron deficiency anaemia (IDA)], normocytic normochromia with anaemia in the absence of malaria parasitaemia (physiological anaemia of pregnancy). RESULTS: Of the 279 pregnant women enrolled, 57% had anaemia. Malaria parasitaemia was associated with 23.3% of anaemic cases while 76.7% were non-malaria related. The distribution of red cell alterations was as follows: hypochromasia (32.6%), microcytosis (14.7%) and macrocytosis (1.1%). The co-occurrence of malaria parasitaemia, iron deficiency and anaemia was seen in 23.3% of the women, iron deficiency anaemia only occurred in 35.9% while physiological anaemia of pregnancy was 40.9%. Iron deficiency and physiological anaemia of pregnancy contribute to a greater proportion of anaemia in the study area. PMID- 29187242 TI - Statistical analysis plan for the EuroHYP-1 trial: European multicentre, randomised, phase III clinical trial of the therapeutic hypothermia plus best medical treatment versus best medical treatment alone for acute ischaemic stroke. AB - BACKGROUND: Cooling may reduce infarct size and improve neurological outcomes in patients with ischaemic stroke. In phase II trials, cooling awake patients with ischaemic stroke has been shown to be feasible and safe, but the effects in functional outcomes has not yet been investigated in an adequately sized randomised clinical trial. METHODS/DESIGN: The EuroHYP-1 trial is a multinational, randomised, superiority phase III clinical trial with masked outcome assessment testing the benefits and harms of therapeutic cooling in awake adult patients with acute ischaemic stroke. The outcomes dealt with here include the primary outcome the Rankin score (mRS) at day 91 +/-14 days after randomisation. The secondary and exploratory outcomes at day 91 +/-14 days unless otherwise stated encompassing: (1) death or dependency, defined as mRS score > 2; (2) death; (3) National Institutes of Health Stroke Score; (4) brain infarct size at 48 +/-24 hours; (5) EQ-5D-5 L score, and (6) WHODAS 2.0 score. Other outcomes are: the primary safety outcome serious adverse events; and the incremental cost effectiveness, and cost utility ratios. The analysis sets include (1) the intention-to-treat population, and (2) the per protocol population. The sample size is estimated to 800 patients (5% type 1 and 20% type 2 errors). All analyses are adjusted for the protocol-specified stratification variables (nationality of centre), and the minimisation variables. In the analysis, we use ordinal regression (the primary outcome), logistic regression (binary outcomes), general linear model (continuous outcomes), and the Poisson or negative binomial model (rate outcomes). DISCUSSION: Major adjustments compared with the original statistical analysis plan encompass: (1) adjustment of analyses by nationality; (2) power calculations for the secondary outcomes; (3) to address the multiplicity problem using of a fixed-sequence testing procedure starting with the primary outcome followed by the secondary outcomes ordered according to falling power; (4) assignment of worst possible score to patients who are not alive at the planned date of measurement of the continuous scores; (5) improved imputations; (6) outline of a supplementary exploratory analysis of the temperature measurements and time to death; and (7) substantial reduction of sample size. TRIAL REGISTRATION: Clinicaltrials.gov, identifier: NCT01833312 . 4 April 2013. PMID- 29187244 TI - Social media usage among health care providers. AB - OBJECTIVE: The objective of this study was to evaluate the use of social media among healthcare workers in an attempt to identify how it affects the quality of patient care. RESULTS: An anonymous survey of 35 questions was conducted in South Texas, on 366 healthcare workers. Of the 97% of people who reported owning electronic devices, 87.9% indicated that they used social media. These healthcare workers indicated that they spent approximately 1 h on social media every day. The healthcare workers below the age of 40 were more involved in social media compared to those above 40 (p < 0.05). The use of social media among physicians and nurses was noted to be identical (88% for each group), and both groups encouraged their patients to research their clinical conditions on social media (p < 0.05). A higher number of physicians reported awareness of a social media policy in their hospital compared to nurses (p < 0.05). However, a large proportion of healthcare workers (40%) were unaware of their workplace policy, which could potentially cause a privacy breach of confidential medical information. Further studies are required to evaluate specific effects of these findings on the quality of patient care. PMID- 29187243 TI - Doxycycline induces dysbiosis in female C57BL/6NCrl mice. AB - OBJECTIVE: This study aims to demonstrate the effect of oral doxycycline on fecal microbiota of mice. Doxycycline is a common effector for control of gene expression using the tet-inducible system in transgenic mice. The effect of oral doxycycline on murine gut microbiota has not been reported. We evaluated the effect of doxycycline treatment by sequencing the V4 hypervariable region of the 16S rRNA gene from fecal samples collected during a 4 week course of treatment at a dose of 2 mg/ml in the drinking water. RESULTS: The fecal microbiota of treated animals were distinct from control animals; the decreased richness and diversity were characterized primarily by Bacteroides sp. enrichment. These effects persisted when the treatment was temporarily discontinued for 1 week. These data suggest that doxycycline treatment can induce significant dysbiosis, and its effects should be considered when used in animal models that are or maybe sensitive to perturbation of the gut microbiota. PMID- 29187245 TI - D-beta-Hydroxybutyrate and melatonin for treatment of porcine hemorrhagic shock and injury: a melatonin dose-ranging study. AB - OBJECTIVE: Treatment with a combination of D-beta-hydroxybutyrate (BHB) and melatonin (M) improves survival in hemorrhagic shock models. Our objective was to find the most effective melatonin concentration in combination with 4 molar BHB (4 M BHB). Survival and markers of organ injury were analyzed in pigs exposed to pulmonary contusion, liver crush injury, and hemorrhagic shock and treated with lactated Ringer's solution; 4 M BHB/43 mM M; 4 M BHB/20 mM M; 4 M BHB/10 mM M; 4 M BHB/4.3 mM M; or 4 M BHB/0.43 mM M. This work is an extension of a previously published research study. RESULTS: Survival was highest in pigs receiving 4 M BHB/43 mM M (13/14), followed by lactated Ringer's solution (11/16) and BHB/M with decreased melatonin concentrations (4 M BHB/20 mM M 3/6, 4 M BHB/10 mM M 2/6, 4 M BHB/4.3 mM M 3/6, 4 M BHB/0.43 mM M 1/6, p = 0.011). High mortality was associated with increases in serum lactate, higher liver and muscle injury markers and decreases in PaO2:FiO2 ratios. Our study indicates that treatment with 4 M BHB and melatonin concentrations below 43 mM lack the survival benefit observed from 4 M BHB/43 mM melatonin in pigs experiencing hemorrhagic shock and polytrauma. PMID- 29187246 TI - Comparison of Bispectral IndexTM values during the flotation restricted environmental stimulation technique and results for stage I sleep: a prospective pilot investigation. AB - OBJECTIVE: To determine whether Bispectral IndexTM values obtained during flotation-restricted environment stimulation technique have a similar profile in a single observation compared to literature-derived results found during sleep and other relaxation-induction interventions. RESULTS: Bispectral IndexTM values were as follows: awake-state, 96.6; float session-1, 84.3; float session-2, 82.3; relaxation-induction, 82.8; stage I sleep, 86.0; stage II sleep, 66.2; and stages III-IV sleep, 45.1. Awake-state values differed from float session-1 (%difference 12.7%; Cohen's d = 3.6) and float session-2 (%difference 14.8%; Cohen's d = 4.6). Relaxation-induction values were similar to float session-1 (%difference 1.8%; Cohen's d = 0.3) and float session-2 (%difference 0.5%; Cohen's d = 0.1). Stage I sleep values were similar to float session-1 (%difference 1.9%; Cohen's d = 0.4) and float session-2 (%difference 4.3%; Cohen's d = 1.0). Stage II sleep values differed from float session-1 (%difference 21.5%; Cohen's d = 4.3) and float session-2 (%difference 19.6%; Cohen's d = 4.0). Stages III-IV sleep values differed from float session-1 (%difference 46.5%; Cohen's d = 5.6) and float session-2 (%difference 45.2%; Cohen's d = 5.4). Bispectral IndexTM values during flotation were comparable to those found in stage I sleep and nadir values described with other relaxation-induction techniques. PMID- 29187247 TI - Improvement of renal function after human umbilical cord mesenchymal stem cell treatment on chronic renal failure and thoracic spinal cord entrapment: a case report. AB - BACKGROUND: Chronic renal failure is an important clinical problem with significant socioeconomic impact worldwide. Thoracic spinal cord entrapment induced by a metabolic yield deposit in patients with renal failure results in intrusion of nervous tissue and consequently loss of motor and sensory function. Human umbilical cord mesenchymal stem cells are immune naive and they are able to differentiate into other phenotypes, including the neural lineage. Over the past decade, advances in the field of regenerative medicine allowed development of cell therapies suitable for kidney repair. Mesenchymal stem cell studies in animal models of chronic renal failure have uncovered a unique potential of these cells for improving function and regenerating the damaged kidney. CASE PRESENTATION: We report a case of a 62-year-old ethnic Indonesian woman previously diagnosed as having thoracic spinal cord entrapment with paraplegic condition and chronic renal failure on hemodialysis. She had diabetes mellitus that affected her kidneys and had chronic renal failure for 2 years, with creatinine level of 11 mg/dl, and no urinating since then. She was treated with human umbilical cord mesenchymal stem cell implantation protocol. This protocol consists of implantation of 16 million human umbilical cord mesenchymal stem cells intrathecally and 16 million human umbilical cord mesenchymal stem cells intravenously. Three weeks after first intrathecal and intravenous implantation she could move her toes and her kidney improved. Her creatinine level decreased to 9 mg/dl. Now after 8 months she can raise her legs and her creatinine level is 2 mg/dl with normal urinating. CONCLUSIONS: Human umbilical cord mesenchymal stem cell implantations led to significant improvement for spinal cord entrapment and kidney failure. The major histocompatibility in allogeneic implantation is an important issue to be addressed in the future. PMID- 29187248 TI - Operational research within the national tuberculosis control programme in Benin. AB - OBJECTIVE: To document whether the placement of operational research (OR) fellows within disease control programmes in low and middle income countries leads to the implementation of operational research and improvements in policy and practice. RESULT: In 2012, an OR fellow was placed within the National TB Programme, Benin, to strengthen the implementation of operational research. From 2012 to 2015, eight OR projects were implemented, of which three contributed to changes in programme practice and five provided information which was not previously available from quarterly/annual reports. Two of these projects-one on the burden and treatment outcomes of childhood TB and one on tracing patients who had discontinued treatment-are discussed in more detail. OR should be strongly encouraged within national TB programme settings and an OR fellow facilitates this process. PMID- 29187249 TI - Interventions to increase adherence in patients taking immunosuppressive drugs after kidney transplantation: a systematic review of controlled trials. AB - BACKGROUND: Immunosuppressive drugs have to be taken through the whole duration of kidney transplant survival to avoid rejection. Low adherence can increase the risk of allograft rejection. The objective was to evaluate the effectiveness of adherence-enhancing interventions (AEI) in kidney transplantation recipients taking immunosuppressive drugs. METHODS: A search was performed in Medline, Embase, CINAHL, and PsycINFO. The search was performed in May 2016. We included comparative studies on AEI for kidney transplant recipients taking immunosuppressive drugs. The primary outcome was medication adherence. All identified articles were screened according to the predefined inclusion criteria. The risk of bias was assessed with the Cochrane risk of bias tool. Study selection and risk of bias assessment were performed by two reviewers independently. Data were extracted in standardized tables. Data extraction was verified by a second reviewer. All discrepancies were resolved through discussion. Data were synthesized in a structured narrative way. There is no registered or published protocol for this systematic review. RESULTS: We identified 12 studies. The number of participants ranged from 24 to 1830. Nine studies included adults, two children, and one adults and children. Risk of bias was high. The main reasons for high risk of bias were inadequate allocation sequence (confounding) and that studies were not blinded. Eleven studies evaluated AEI consisting of educational and/or behavioral components. All these studies showed an effect direction in favor of the intervention. Intervention effect was only moderate. Most adherence measures in studies on educational and behavioral interventions showed statistically significant differences. Studies that combined educational and behavioral intervention components showed larger effects. All studies that were statistically significant were multimodal. Studies that included an individualized component and more intensive interventions showed larger effects. One study evaluated a reminder system. Effect size was not reported. This study showed no statistical significant difference (p > 0.05). CONCLUSION: Educational and behavioral AEI can increase adherence. In particular, multimodal and individualized interventions seem promising. However, because of the small effect, the high risk of bias, and the invalidity of adherence measures, the actual benefit of adherence interventions for an unselected patient population (i.e., including also adherent patients) seems limited. No conclusion is possible for interventions combining adherence-enhancing components that address intentional (behavioral) as well as unintentional adherence (reminder). PMID- 29187250 TI - Polymorphism rs13334190 in zinc finger protein 469 (ZNF469) is not a risk factor for keratoconus in a Saudi cohort. AB - OBJECTIVE: Polymorphism rs13334190 in the zinc finger protein 469 gene has been suggested to predispose toward a "thin" cornea, which then becomes keratoconic or is directly pathogenic. Thus, we genotyped polymorphism rs13334190 in 127 unrelated keratoconus cases and 168 control subjects from Saudi Arabia using Taq Man(r) assay. RESULTS: The genotype frequency distribution did not deviate significantly from the Hardy-Weinberg equilibrium (p > 0.05). Overall, both the genotype and allele frequencies were not significantly different between cases and controls. A minor allele frequency of 0.068 was comparable to the aggregate rates ranging from 0.060 to 0.086 observed in other populations. Binary logistic regression analysis was performed to ascertain the effects of age, gender and genotype on the likelihood of having keratoconus. The analysis indicated that increased age was statistically significant (p = 0.000) and that females have a 2.19-fold increased risk (p = 0.018) of developing keratoconus. The genotype frequencies did not differ between the sporadic or familial keratoconus cases. Polymorphism rs13334190 is not an independent risk factor for keratoconus in the Saudi cohort. PMID- 29187251 TI - Experiencing physical warmth affects implicit attitudes and altruistic behavior toward outgroup in females. AB - OBJECTIVE: Experiencing physical warmth has been demonstrated to influence interpersonal warmth. However, the effects of this metaphorical link in an intergroup context is not clear. The current study aimed to investigate the effect of physical warmth on implicit attitudes and behavior toward outgroup members in a Japanese-Chinese intergroup context. After touching either a warm or cold cup for 3 min, the Japanese participants were required to complete the single-target implicit association test, which aimed to measure their implicit attitudes toward imagined Chinese people, and to express their willingness to participate in the experiments of a Chinese individual whom they interacted directly without compensation, aiming to measure their prosocial behavior toward a real outgroup member. RESULTS: The results demonstrated that female participants who touched the warm (vs. cold) cup showed more positive attitudes and helping behavior toward the Chinese individual. Furthermore, the correlation between those attitudes and helping behaviors supports the effects of enhanced implicit attitudes and further suggests that experiencing physical warmth could increase prosocial response to outgroup members in real interactions. However, the male participants showed a reversed, but not statistically significant, effect of physical warmth on the implicit attitude. PMID- 29187254 TI - Acute disseminated melioidosis giving rise to pneumonia and renal abscesses complicated with thrombotic thrombocytopenic purpura in a post partum woman: a case report. AB - BACKGROUND: Melioidosis is an established endemic infection in Sri Lanka, caused by Burkholderia pseudomallei, a gram negative bacterium distributed in saprophytes in soil and surface water. Main mode of transmission is via percutaneous inoculation. Pneumonia is the most common presentation in acute disease. CASE PRESENTATION: We report a 33 year old previously healthy Sinhalese female with an occupational exposure to surface water in paddy fields, who was on postpartum day 6 following an uncomplicated pregnancy and delivery via an elective caesarian section. She presented with a 1 day history of breathlessness, preceded by a brief episode of fever. She had occasional right side coarse crackles and pitting oedema of both lower limbs. Shortly after admission, she developed type one respiratory failure needing invasive mechanical ventilation. Initial chest x-ray revealed slight obliteration of right medial diaphragmatic border while echocardiogram revealed moderate pulmonary hypertension. Computed tomography pulmonary angiogram excluded a pulmonary embolism, but revealed bilateral multi-lobar consolidation. Abdominal computed tomography demonstrated bilateral pyelonephritis with renal abscesses. As initial cultures were inconclusive, melioidosis antibody levels were done due to high degree of suspicion, which was found to be positive with a titer of 1:2560. A diagnosis of melioidosis was made based on the suggestive clinical picture, exposure history and the highly positive antibody level. She developed left side focal seizures together with thrombocytopenia and microangiopathic haemolytic anemia, suggestive of thrombotic thrombocytopenic purpura. Magnetic resonance imaging of brain was negative for cerebral abscesses but revealed extensive minute haemorrhagic foci throughout the cerebrum. Thus, the final diagnosis was acute melioidosis causing pneumonia and renal abscesses, complicated with thrombotic thrombocytopenic purpura and sepsis. She demonstrated dramatic response to high dose meropenem and co-trimoxazole along with plasmapheresis. Four weeks after treatment, the antibody titer came down to 1:320. Melioidosis antibody was absent in the baby. CONCLUSIONS: This case was challenging as it was an atypical presentation of melioidosis during postpartum leading to a diagnostic conundrum. This highlights the need to look into the effect of pregnancy and postpartum as added risk factors. High index of suspicion is necessary to avoid diagnostic delays. PMID- 29187252 TI - Atypical, non-standard functions of the microtubule associated Tau protein. AB - Since the discovery of the microtubule-associated protein Tau (MAPT) over 40 years ago, most studies have focused on Tau's role in microtubule stability and regulation, as well as on the neuropathological consequences of Tau hyperphosphorylation and aggregation in Alzheimer's disease (AD) brains. In recent years, however, research efforts identified new interaction partners and different sub-cellular localizations for Tau suggesting additional roles beyond its standard function as microtubule regulating protein. Moreover, despite the increasing research focus on AD over the last decades, Tau was only recently considered as a promising therapeutic target for the treatment and prevention of AD as well as for neurological pathologies beyond AD e.g. epilepsy, excitotoxicity, and environmental stress. This review will focus on atypical, non standard roles of Tau on neuronal function and dysfunction in AD and other neurological pathologies providing novel insights about neuroplastic and neuropathological implications of Tau in both the central and the peripheral nervous system. PMID- 29187253 TI - Diffusion tensor imaging and tractography of the sciatic and femoral nerves in healthy volunteers at 3T. AB - BACKGROUND: The aim was to clarify the normal fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values of the sciatic and femoral nerves at the level of the hip joint and to visualize the neural tracts with diffusion tensor imaging (DTI). METHODS: Twenty-four healthy volunteers (12 men and 12 women, age 20-29 years) underwent DTI for visualization with tractography and quantification of FA and ADC values on a 3 Tesla MRI (b value = 800 s/mm2, motion probing gradient, 11 directions, time to repeat/echo time = 9000/72.6 ms, axial slice orientation, slice thickness = 3.0 mm with no inter-slice gap, field of view = 320 * 320 mm, 96 * 192 matrix, 75 slices, number of acquisitions = 4). Regions of interest in the sciatic nerve were defined at the femoral head, the S1 root, and the midpoint levels. The femoral nerve was evaluated at 3-4 cm proximal to the femoral head level. RESULTS: The tractography of the sciatic and femoral nerves were visualized in all participants. The mean FA values of the sciatic nerve were increased distally from the S1 root level, through the midpoint, and to the femoral head level (0.314, 0.446, 0.567, p = 0.001, respectively). The mean FA values of the femoral nerve were 0.565. The mean ADC values of the sciatic nerves were significantly lower in the S1 root level than in the midpoint and the femoral head level (1.481, 1.602, 1.591 * 10-3 * 10-3 mm2/s, p = 0.001, respectively). The ADC values of the femoral nerve were 1.439 * 10-3 mm2/s. FA and ADC values showed moderate to substantial inter- and intra-observer reliability without significant differences in gender or laterality. CONCLUSION: Visualization and quantification of the sciatic and femoral nerves simultaneously around the hip joint were achieved in healthy young volunteers with DTI. Clinical application of DTI is expected to contribute to hip pain research. PMID- 29187255 TI - A novel loop-mediated isothermal amplification-based test for detecting Neospora caninum DNA. AB - BACKGROUND: Neospora caninum is a cyst-forming, coccidian parasite which is known to cause neurological disorders in dogs and abortion and neonatal mortality in cows and other livestock. This study reports the development of a loop-mediated isothermal amplification (LAMP) assay based on the Neospora caninum Nc-5 gene and compares its efficacy for detecting DNA to that of a semi-nested PCR test. RESULTS: Six primers were designed based on the Nc-5 repeat region of N. caninum. Specific LAMP primers led to successful amplification of N. caninum DNA at 63 degrees C in 30 min. The LAMP assay was highly specific (i.e. it did not reveal cross-reactivity with other parasite species) and had a low N. caninum plasmid DNA limit of detection (1 fg), which is ten times higher than that for the semi nested PCR. LAMP applicability was evaluated using a set of naturally-infected samples (59 from canine faeces and five from bovine abortions). Thirty-nine percent (25/64) of the naturally-infected samples were positive for N. caninum DNA by LAMP and 36% (23/64) by semi-nested PCR. However, the LAMP assay is much faster to perform than semi-nested PCR and provides results in 30 min. CONCLUSION: The optimized reaction conditions described in this study resulted in a sensitive, specific and rapid technique for detecting N. caninum DNA. Considering the advantages of LAMP for detecting N. caninum DNA, further assays aimed at testing its usefulness on a wider range of field samples are recommended. PMID- 29187257 TI - Urbanization, economic development and health: evidence from China's labor-force dynamic survey. AB - BACKGROUND: The frequent outbreak of environmental threats in China has resulted in increased criticism regarding the health effects of China's urbanization. Urbanization is a double-edged sword with regard to health in China. Although great efforts have been made to investigate the mechanisms through which urbanization influences health, the effect of both economic development and urbanization on health in China is still unclear, and how urbanization-health (or development-health) relationships vary among different income groups remain poorly understood. To bridge these gaps, the present study investigates the impact of both urbanization and economic development on individuals' self-rated health and its underlying mechanisms in China. METHODS: We use data from the national scale of the 2014 China Labor-force Dynamics Survey to analyze the impact of China's urbanization and economic development on health. A total of 14,791 individuals were sampled from 401 neighborhoods within 124 prefecture level cities. Multilevel ordered logistic models were applied. RESULTS: Model results showed an inverted U-shaped relationship between individuals' self-rated health and urbanization rates (with a turning point of urbanization rate at 42.0%) and a positive linear relationship between their self-rated health and economic development. Model results also suggested that the urbanization-health relationship was inverted U-shaped for high- and middle-income people (with a turning point of urbanization rate at 0.0% and 49.2%, respectively), and the development-health relationship was inverted U-shaped for high- and low-income people (with turning points of GDP per capita at 93,462 yuan and 71,333 yuan, respectively) and linear for middle-income people. CONCLUSION: The impact of urbanization and economic development on health in China is complicated. Careful assessments are needed to understand the health impact of China's rapid urbanization. Social and environmental problems arising from rapid urbanization and economic growth should be addressed. Equitable provision of health services are needed to improve low-income groups' health in highly urbanized cities. PMID- 29187256 TI - Astrocytes in mouse models of tauopathies acquire early deficits and lose neurosupportive functions. AB - Microtubule-associated protein tau aggregates constitute the characteristic neuropathological features of several neurodegenerative diseases grouped under the name of tauopathies. It is now clear that the process of tau aggregation is associated with neurodegeneration. Several transgenic tau mouse models have been developed where tau progressively aggregates, causing neuronal death. Previously we have shown that transplantation of astrocytes in P301S tau transgenic mice rescues cortical neuron death, implying that the endogenous astrocytes are deficient in survival support. We now show that the gliosis markers Glial fibrillary acidic protein (GFAP) and S100 calcium-binding protein B (S100beta) are elevated in brains from P301S tau mice compared to control C57Bl/6 mice whereas the expression of proteins involved in glutamine/glutamate metabolism are reduced, pointing to a functional deficit. To test whether astrocytes from P301S mice are intrinsically deficient, we co-cultured astrocytes and neurons from control and P301S mice. Significantly more C57-derived and P301S-derived neurons survived when cells were cultured with C57-derived astrocytes or astrocyte conditioned medium (C57ACM) than with P301S-derived astrocytes or astrocyte conditioned medium (P301SACM), or ACM from P301L tau mice, where the transgene is also specifically expressed in neurons. The astrocytic alterations developed in mice during the first postnatal week of life. In addition, P301SACM significantly decreased presynaptic (synaptophysin, SNP) and postsynaptic (postsynaptic density protein 95, PSD95) protein expression in cortical neuron cultures whereas C57ACM enhanced these markers. Since thrombospondin 1 (TSP-1) is a major survival and synaptogenic factor, we examined whether TSP-1 is deficient in P301S mouse brains and ACM. Significantly less TSP-1 was expressed in the brains of P301S tau mice or produced by P301S-derived astrocytes, whereas supplementation of P301SACM with TSP-1 increased its neurosupportive capacity. Our results demonstrate that P301S derived astrocytes acquire an early functional deficiency that may explain in part the loss of cortical neurons in the P301S tau mice. PMID- 29187258 TI - Medical educators' perception of communication training with simulated patients: an explorative study approach. AB - OBJECTIVE: Medical students' perceptions of the use of simulated patients (SP) in communication training in medicine have been studied intensively, but insights about faculty perception of this type of simulation training remain rare. This study aimed to assess medical educators' perception of the relevancy of SP communication training, as well as its closeness to reality. Medical educators were surveyed by standardized questionnaire and open-ended questions. The questionnaire allowed educators to rate several aspects of the training such as its closeness to reality and relevancy to real-life physician-patient interaction. RESULTS: Educators' perception of relevance and realism of SP training increases with teaching experience. This appears to be influenced by factors such as internal or external status of the educator, personal experience with communication training during medical studies, as well as medical field taught. Communication training with SP is valued highly by medical educators mainly because of its versatility and broad spectrum of applicability. The wide range of application of SP in medical education seems most evident to senior educators because of their increased amount of experience with physician-patient interaction, whereas junior educators appear often hindered by the aspect of simulation caused by the thought that the patients are "merely" actors. PMID- 29187260 TI - Histological changes of the meniscus following an osteochondral lesion. AB - In the last few years, different tissue engineering strategies have been developed for the repair of osteochondral lesions. When the osteochondral scaffold is implanted on the femoral condyle, the meniscus might be affected by the implant and might undergo a progressive degeneration. The aim of our study is to analyze the morphological changes of the meniscus following an osteochondral lesion and the implant of a biphasic scaffold. A critical osteochondral defect was generated in the medial femoral condyle of mature sheep. Three defects were left untreated, the remaining lesions were divided into three groups and treated with a biphasic substituted formed by collagen type I and Wollastonite or Wollastonite/Hydroxyapatite. Animals were sacrificed after 6 months and menisci were isolated and analyzed by arthro-CT, macroscopic evaluation and histology. The results demonstrated that the osteochondral lesion negatively affects meniscus morphology and that the osteochondral substitute only partially mitigates the meniscus degeneration. PMID- 29187259 TI - Impact of IQ on the diagnostic yield of chromosomal microarray in a community sample of adults with schizophrenia. AB - BACKGROUND: Schizophrenia is a severe psychiatric disorder associated with IQ deficits. Rare copy number variations (CNVs) have been established to play an important role in the etiology of schizophrenia. Several of the large rare CNVs associated with schizophrenia have been shown to negatively affect IQ in population-based controls where no major neuropsychiatric disorder is reported. The aim of this study was to examine the diagnostic yield of microarray testing and the functional impact of genome-wide rare CNVs in a community ascertained cohort of adults with schizophrenia and low (< 85) or average (>= 85) IQ. METHODS: We recruited 546 adults of European ancestry with schizophrenia from six community psychiatric clinics in Canada. Each individual was assigned to the low or average IQ group based on standardized tests and/or educational attainment. We used rigorous methods to detect genome-wide rare CNVs from high-resolution microarray data. We compared the burden of rare CNVs classified as pathogenic or as a variant of unknown significance (VUS) between each of the IQ groups and the genome-wide burden and functional impact of rare CNVs after excluding individuals with a pathogenic CNV. RESULTS: There were 39/546 (7.1%; 95% confidence interval [CI] = 5.2-9.7%) schizophrenia participants with at least one pathogenic CNV detected, significantly more of whom were from the low IQ group (odds ratio [OR] = 5.01 [2.28-11.03], p = 0.0001). Secondary analyses revealed that individuals with schizophrenia and average IQ had the lowest yield of pathogenic CNVs (n = 9/325; 2.8%), followed by those with borderline intellectual functioning (n = 9/130; 6.9%), non-verbal learning disability (n = 6/29; 20.7%), and co-morbid intellectual disability (n = 15/62; 24.2%). There was no significant difference in the burden of rare CNVs classified as a VUS between any of the IQ subgroups. There was a significantly (p=0.002) increased burden of rare genic duplications in individuals with schizophrenia and low IQ that persisted after excluding individuals with a pathogenic CNV. CONCLUSIONS: Using high-resolution microarrays we were able to demonstrate for the first time that the burden of pathogenic CNVs in schizophrenia differs significantly between IQ subgroups. The results of this study have implications for clinical practice and may help inform future rare variant studies of schizophrenia using next-generation sequencing technologies. PMID- 29187262 TI - Novel circulating microRNAs expression profile in colon cancer: a pilot study. AB - PURPOSE: To identify the expression profile of novel microRNAs (miRNAs) in colon cancer and evaluate their clinical applicability. METHODS: Differences in the expression of serum miRNAs in patients with colon cancer and healthy controls were identified using miRNA microarrays. Differentially expressed miRNAs were verified via real-time polymerase chain reaction (PCR) using sera from 50 patients with colon cancer and 44 healthy controls. These miRNAs were also verified in a double-blind validation experiment using sera from 30 patients with colon cancer, 30 patients with colonic polyps, and 30 healthy controls. RESULTS: Microarray hybridization revealed that 87 miRNAs were differentially expressed between the sera of patients with colon cancer and healthy controls. Among these miRNAs, 39 miRNAs were up-regulated, whereas 48 miRNAs were down-regulated. Verification of the expression of these miRNAs using real-time PCR revealed that the expression levels of miR-31, miR-141, miR-224-3p, miR-576-5p, and miR-4669 were significantly different between patients with colon cancer and healthy controls. Using these five miRNAs to construct a miRNA expression profile (or miRNA panel) will facilitate more effective diagnosis of colon cancer. CONCLUSION: Clinical analysis of miR-31, miR-141, miR-224-3p, miR-576-5p, and miR 4669 expression in patients with colon cancer may facilitate the diagnosis of colon cancer. PMID- 29187264 TI - Quantitation and Confirmation of Chloramphenicol, Florfenicol, and Nitrofuran Metabolites in Honey Using LC-MS/MS. AB - This paper describes a rapid and robust method utilizing a single liquid-liquid extraction for the quantitation and confirmation of chloramphenicol, florfenicol, and nitrofuran metabolites in honey. This methodology combines two previous extraction methods into a single extraction procedure and utilizes matrix-matched calibration standards and stable isotopically labeled standards to improve quantitation. The combined extraction procedure reduces the average extraction time by >50% when compared with previously used procedures. The drug residues were determined using two separate LC-tandem MS conditions. Validation of all the analytes was performed, with average quantitation ranging from 92 to 105% for all analytes and the RSDs for all analytes being <=12%. PMID- 29187265 TI - Development and Evaluation of an Enzyme-Linked Immunosorbent Assay Using a Nonpoisonous Extraction System for the Determination of Crustacean Protein in Processed Foods. AB - Crustacean proteins are food allergens that cause severe allergic reactions in patients with food allergies; therefore, the identification of crustaceans such as shrimp, crab, and lobster as ingredients in processed food products is mandatory in Japan. We previously developed and validated an ELISA method coupled with an extraction process using the surfactant sodium dodecyl sulfate and the reductant 2-mercaptoethanol (2-ME) to quantify crustacean protein. However, 2-ME was designated as poisonous in Japan in 2008. Therefore, in this study, we developed and evaluated an ELISA method for detecting and quantifying crustacean protein that uses sodium sulfite (Na2SO3) in place of 2-ME for extraction. The proposed ELISA method showed high sensitivity, with an LOQ of 0.66 MUg protein/g food sample. Furthermore, the proposed method showed high specificity for the Decapoda order within the subphylum Crustacea, with recoveries ranging from 83.8 to 100.8% for model processed foods, as well as high reproducibility (intra- and interassay CVs of <=8.2%) and high correlation with our previously validated ELISA method for processed foods (correlation coefficient of 0.996). The proposed ELISA method does not require the use of poisonous reagents, provides acceptable accuracy, and is useful for the routine monitoring of food products.

PMID- 29187266 TI - Guidance for compassionate restraint of small children to prevent injuries with epinephrine autoinjectors. AB - BACKGROUND: Without securing a child properly, injuries can happen with the use of pediatric epinephrine autoinjectors (EAI), and lacerations and embedded needles have been reported. Health care providers should ensure that instruction is provided to parents on how to hold a child during an injection with an EAI. OBJECTIVE: To demonstrate the compassionate restraint of small children during an allergic emergency to ensure the safe use of an EAI. METHODS: A patient was used to illustrate a compassionate restraint technique during a mock injection with an EAI. RESULTS: One possible technique was illustrated here to reinforce the need for complete, yet compassionate restraint of small children during the use of an EAI. The exact position intended to be used by parents or caregivers will need to be practiced with their children to ensure a safe injection in the event of an allergic emergency. CONCLUSION: Reinforcement of proper EAI use and visual guidance that illustrate compassionate restraint can potentially prevent EAI related injuries. PMID- 29187261 TI - Initial nutritional management during noninvasive ventilation and outcomes: a retrospective cohort study. AB - BACKGROUND: Patients starting noninvasive ventilation (NIV) to treat acute respiratory failure are often unable to eat and therefore remain in the fasting state or receive nutritional support. Maintaining a good nutritional status has been reported to improve patient outcomes. In the present study, our primary objective was to describe the nutritional management of patients starting first line NIV, and our secondary objectives were to assess potential associations between nutritional management and outcomes. METHODS: Observational retrospective cohort study of a prospective database fed by 20 French intensive care units. Adult medical patients receiving NIV for more than 2 consecutive days were included and divided into four groups on the basis of nutritional support received during the first 2 days of NIV: no nutrition, enteral nutrition, parenteral nutrition only, and oral nutrition only. RESULTS: Of the 16,594 patients admitted during the study period, 1075 met the inclusion criteria; of these, 622 (57.9%) received no nutrition, 28 (2.6%) received enteral nutrition, 74 (6.9%) received parenteral nutrition only, and 351 (32.7%) received oral nutrition only. After adjustment for confounders, enteral nutrition (vs. no nutrition) was associated with higher 28-day mortality (adjusted HR, 2.3; 95% CI, 1.2-4.4) and invasive mechanical ventilation needs (adjusted HR, 2.1; 95% CI, 1.1 4.2), as well as with fewer ventilator-free days by day 28 (adjusted relative risk, 0.7; 95% CI, 0.5-0.9). CONCLUSIONS: Nearly three-fifths of patients receiving NIV fasted for the first 2 days. Lack of feeding or underfeeding was not associated with mortality. The optimal route of nutrition for these patients needs to be investigated.

AB - Non-small cell lung cancer (NSCLC) is one of the most deadly cancers with poor prognosis. Recent findings suggested that the lncRNA HOTAIR played an important role in tumorigenesis and metastasis. In the present study, HOTAIR was highly expressed in NSCLC tumor tissues and cell lines (H1299, H23, H292, and A549). Downregulation of HOTAIR suppressed cell proliferation and invasion, while it promoted apoptosis of NSCLC cells. The targeting relationship between HOTAIR and miR-613 was first revealed by bioinformatics prediction. miR-613 was found to be lowly expressed in NSCLC tumor tissues and cell lines. Knockdown of HOTAIR increased the expression of miR-613 significantly, and cotransfection with miR 613 inhibitor reversed this increase, indicating that the expression of miR-613 was negatively regulated by HOTAIR. The targeting relationship between HOTAIR and miR-613 was further confirmed through the luciferase report assay. Moreover, the cotransfection of HOTAIR shRNA and miR-613 inhibitor counteracted the tumor inhibition effects of HOTAIR shRNA through promoting cell proliferation and invasion while suppressing apoptosis in NSCLC cells, suggesting that the HOTAIR/miR-613 axis was involved in tumorigenesis and metastasis of NSCLC. In vivo experiments revealed that knockdown of HOTAIR decreased tumor growth and invasion and increased apoptosis and miR-613 expression. In conclusion, our study indicated that downregulation of HOTAIR suppressed tumorigenesis and metastasis of NSCLC via upregulating the expression of miR-613. The HOTAIR/miR-613 axis might provide a new potential therapeutic strategy for NSCLC treatment. PMID- 29187269 TI - Ophthalmic Paracoccidioidomycosis.

AB - Previous studies have demonstrated that the presence of larvae of other filarial species in Simulium damnosum sensu lato can distort estimates of transmission potential for Onchocerca volvulus in West Africa. However, studies conducted in foci of onchocerciasis in West Central Uganda indicated that larvae other than O. volvulus were not common in vectors collected there. Recent data collected in Northern Uganda revealed a striking discordance between estimates of the prevalence of flies carrying O. volvulus infective larvae obtained from molecular pool screening and dissection methods. To resolve this discrepancy, sequences from three mitochondrially encoded genes were analyzed from the larvae collected by dissection. All larvae analyzed were Onchocerca ochengi v. Siisa, a parasite of cattle, or Onchocerca ramachandrini, a parasite of warthogs. These results suggest that nonhuman parasite larvae are common in vectors in Northern Uganda, underscoring the necessity for molecular identification methods to accurately estimate O. volvulus transmission.

AB - Scientists planning research that involves the use of animals are required to examine the possibilities for replacement, reduction, or refinement (the Three Rs), and their protocol must be reviewed by the Institutional Animal Care and Use Committee. Good scientific practice involving appropriate search techniques on the available Three Rs resources is essential for both ethical and scientific reasons. Appropriate experimental design and statistical analysis techniques are particularly necessary for research involving the use of animals, because this can improve animal welfare and scientific outcomes, as well as saving animal lives. There are a number of resources to help researchers improve their search techniques, experimental design strategies, and their reporting of research involving the use of animals. However, there is little specific information or resources on the Three Rs alternatives that is readily available in the Korean language. This paper outlines the common errors made by submitting researchers that have been repeatedly observed during the ethical review of experimental protocols over the last ten years, and provides information on the Korean resources available to promote good scientific practice. This could help to bridge the gap between Korean scientists and animal welfare advocates assisting scientists to improve ethical considerations and conduct responsible research.

AB - Mammalian target of rapamycin complex 1 (mTORC1) plays a major role in cell growth, proliferation, polarity, differentiation, development, and controls transitioning between anabolic and catabolic states of the cell. It collects almost all extracellular and intracellular signals from growth factors, nutrients, and maintains cellular homeostasis, and is involved in several pathological conditions including, neurodegeneration, Type 2 diabetes (T2D), obesity, and cancer. In this review, we summarize current knowledge of upstream signaling of mTORC1 to explain etiology of T2D and hypertriglyceridemia, in which state, the role of telomere attrition is explained. We discuss if chronic inhibition of mTORC1 can reverse adverse effects resulting from hyperactivation. In conclusion, we suggest the regulatory roles of telomerase (TERT) and hexokinase II (HKII) on mTORC1 as possible remedies to treat hyperactivation. The former inhibits mTORC1 under nutrientrich while the latter under starved condition. We provide an idea of TOS (TOR signaling) motifs that can be used for regulation of mTORC1.

PMID- 29187282 TI - Prevalence of negative frequency-dependent selection, revealed by incomplete selective sweeps in African populations of Drosophila melanogaster. AB - Positive selection on a new beneficial mutation generates a characteristic pattern of DNA sequence polymorphism when it reaches an intermediate allele frequency. On genome sequences of African Drosophila melanogaster, we detected such signatures of selection at 37 candidate loci and identified "sweeping haplotypes (SHs)" that are increasing or have increased rapidly in frequency due to hitchhiking. Based on geographic distribution of SH frequencies, we could infer whether selective sweeps occurred starting from de novo beneficial mutants under simple constant selective pressure. Single SHs were identified at more than half of loci. However, at many other loci, we observed multiple independent SHs, implying soft selective sweeps due to a high beneficial mutation rate or parallel evolution across space. Interestingly, SH frequencies were intermediate across multiple populations at about a quarter of the loci despite relatively low migration rates inferred between African populations. This invokes a certain form of frequency-dependent selection such as heterozygote advantage. At one locus, we observed a complex pattern of multiple independent that was compatible with recurrent frequency-dependent positive selection on new variants. In conclusion, genomic patterns of positive selection are very diverse, with equal contributions of hard and soft sweeps and a surprisingly large proportion of frequencydependent selection in D. melanogaster populations.

AB - Sterol regulatory element-binding protein-1c (SREBP1c) plays an important role in triglyceride (TG) homeostasis. Although our previous study showed that hepatitis C virus core-binding protein 6 (HCBP6) regulates SREBP1c expression to maintain intracellular TG homeostasis, the mechanism underlying this regulation is unclear. In the present study, we found that HCBP6 increased intracellular TG levels by upregulating SREBP1c expression. HCBP6 increased SREBP1c transcription by directly binding to the SREBP1c promoter (at the -139- to +359-bp region). Moreover, we observed that HCBP6 interacted with C/EBPbeta-binding site in the SREBP1c promoter both in vitro and in vivo. These results indicate that HCBP6 upregulates human SREBP1c expression by binding to the C/EBPbeta-binding site in the SREBP1c promoter. [BMB Reports 2018; 51(1): 33-38]. PMID- 29187283 TI - New insight into transglutaminase 2 and link to neurodegenerative diseases. AB - Formation of toxic protein aggregates is a common feature and mainly contributes to the pathogenesis of neurodegenerative diseases (NDDs), which include amyotrophic lateral sclerosis (ALS), Alzheimer's, Parkinson's, Huntington's, and prion diseases. The transglutaminase 2 (TG2) gene encodes a multifunctional enzyme, displaying four types of activity, such as transamidation, GTPase, protein disulfide isomerase, and protein kinase activities. Many studies demonstrated that the calcium-dependent transamidation activity of TG2 affects the formation of insoluble and toxic amyloid aggregates that mainly consisted of NDD-related proteins. So far, many important and NDD-related substrates of TG2 have been identified, including amlyoid-beta, tau, alpha-synuclein, mutant huntingtin, and ALS-linked trans-activation response (TAR) DNA-binding protein 43. Recently, the formation of toxic inclusions mediated by several TG2 substrates were efficiently inhibited by TG2 inhibitors. Therefore, the development of highly specific TG2 inhibitors would be an important tool in alleviating the progression of TG2-related brain disorders. In this review, the authors discuss recent advances in TG2 biochemistry, several mechanisms of molecular regulation and pleotropic signaling functions, and the presumed role of TG2 in the progression of many NDDs.

PMID- 29187284 TI - JQ1, a BET inhibitor, controls TLR4-induced IL-10 production in regulatory B cells by BRD4-NF-kappaB axis. AB - Regulatory B cells, also well-known as IL-10-producing B cells, play a role in the suppression of inflammatory responses. However, the epigenetic modulation of regulatory B cells is largely unknown. Recent studies showed that the bromodomain and extra-terminal domain (BET) protein inhibitor JQ1 controls the expression of various genes involving cell proliferation and cell cycle. However, the role of BET proteins on development of regulatory B cells is not reported. In this study, JQ1 potently suppressed IL-10 expression and secretion in murine splenic and peritoneal B cells. While bromodomaincontaining protein 4 (BRD4) was associated with NF-kappaB on IL-10 promoter region by LPS stimulation, JQ1 interfered the interaction of BRD4 with NF-kappaB on IL-10 promoter. In summary, BRD4 is essential for toll like receptor 4 (TLR4)-mediated IL-10 expression, suggesting JQ1 could be a potential candidate in regulating IL-10-producing regulatory B cells in cancer.

PMID- 29187287 TI - Relationship between leptin concentrations and disease activity in patients with rheumatoid arthritis. AB - BACKGROUND AND OBJECTIVE: Multiple studies have found a direct relationship between leptin concentrations and disease activity in rheumatoid arthritis. PATIENTS AND METHODS: We studied 77 patients with the diagnosis of rheumatoid arthritis; the leptin determination was through an enzyme immunoassay. Disease activity was assessed by the DAS-28 CRP. A multivariate logistic regression model was used to determine the association between significant variables and leptin concentrations. RESULTS: 40.3% of the patients were in remission, 41.6% were mildly active, 11.7% were moderately active and 6.5% were severely active. The results show an independent association between higher concentrations of leptin and disease activity (OR 1.7; 95% CI 1.4-3.2; p .03), the number of swollen joints (OR 4.6; 95% CI 1.7-8.3; p .000), the number of painful joints (OR 3.4; 95% CI 1.6-4.6; p .000), and the presence of metabolic syndrome (OR 1.3; 95% IC 1.2-1,9; p .045). CONCLUSION: The data suggest that serum leptin is elevated in patients with active RA. PMID- 29187288 TI - Prognostic Relation Between Severity of Diabetes Mellitus (On or Off Insulin) +/- Chronic Kidney Disease with Cardiovascular Risk After Percutaneous Coronary Intervention. AB - The presence of either diabetes mellitus (DM) or chronic kidney disease (CKD) is associated with a worse prognosis after percutaneous coronary intervention (PCI). It is also known that outcomes in patients treated with insulin (insulin requiring type 2 diabetes mellitus [ITDM]) are worse than those who are not on insulin (non-insulin type 2 diabetes mellitus [NITDM]). We sought to compare long term outcomes in patients who underwent PCI with varying severity of DM with and without CKD. We retrospectively studied 17,898 patients who underwent PCI from January 2009 to December 2014 in the Mount Sinai Cath Lab. Patients were categorized into groups by the presence or the absence of CKD and by the DM status (none, NITDM, or ITDM). In the absence of CKD, adjusted hazard ratios (95% confidence interval [CI]) for death or myocardial infarction associated with NITDM and ITDM were 1.65 (95% CI 1.02 to 2.67) and 3.78 (95% CI 2.23 to 6.40), respectively. Analogous risks in the presence of CKD were 3.34 (95% CI 1.99 to 5.61) and 6.26 (95% CI 3.84 to 10.2). This study shows that irrespective of renal status, the need for insulin in the setting of DM identifies a group with substantial risk of death or myocardial infarction at 1 year.

AB - The radiological characterization of the topsoil of the L-54M reactor surroundings carried out in this work aims at obtaining the reference blank point for the forthcoming decommissioning operations and ascertain if unexpected radionuclide release occurred during the operational life of the plant. Standardised methods have been employed in order to collect representative samples and reliable results. Suitable sample pre-treatment procedures were applied. Gamma and beta spectrometric analyses were carried out to measure the activity concentrations of 60Co 137Cs, 152Eu, 241Am and 90Sr. These have been considered as representative radionuclides that could have been originated from reactor operations and that could still be present at four decades post reactor shutdown.

AB - BACKGROUND: There has been constant discussion about whether the clinical outcome of THA after periacetabular osteotomy (PAO) is equivalent to that after primary total hip arthroplasty (THA). However, there have been few reports about patient reported outcomes (PRO) for those who undergo THA after PAO. We compared the pre- and postoperative PRO of patients who underwent THA after PAO and those who underwent primary THA alone. METHODS: We performed a case-control study. Twenty seven patients (29 hips) underwent THA after PAO (osteotomy group); their mean age at surgery was 57.2 years, and they underwent postoperative follow-up for a mean period of 3.0 years. For the control group, after matching age, sex, and Crowe classification, we included 54 patients (58 joints) who underwent primary THA for hip dysplasia. Assessment performed preoperatively and at the last follow up included the Harris hip score, the Short Form 36 (SF-36) for the Physical Component Summary (PCS), Mental Component Summary (MCS), and Role/Social Component Summary (RCS) domains, Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire (JHEQ) for pain, movement, and mental health, and the visual analog scale (VAS) score of hip pain and satisfaction. RESULTS: The two groups demonstrated no significant difference in the preoperative Harris hip score, each domain of the SF-36, JHEQ, and the VAS score of hip pain and satisfaction. The osteotomy group demonstrated significantly poor Harris hip scores for gait and activity, and JHEQ for movement at the last follow-up. There was no significant difference in each domain of the SF-36 and the VAS score of hip pain and satisfaction at the last follow-up. CONCLUSION: Previous PAO affects the quality of physical function in patients who undergo subsequent THA. PMID- 29187292 TI - Borrelia miyamotoi: Should this pathogen be considered for the diagnosis of tick borne infectious diseases in Spain? AB - INTRODUCTION: Borrelia miyamotoi is a tick-borne pathogen belonging to the relapsing fever group. It had not been reported from Spain, but its wide distribution and the presence of the tick-vector (Ixodes ricinus) made us suspect its circulation. The aim of this study was to investigate the presence of Borrelia spp. in I. ricinus in Spain. METHODS: A total of 652 I. ricinus nymphs collected in northern Spain were processed. The DNA was extracted using incubations with ammonium hydroxide. Borrelia spp. DNA was amplified using Borrelia-specific PCR assays (glpQ, 16S rRNA and flagellin genes). RESULTS: B. miyamotoi was amplified in 4 specimens, and Borrelia burgdorferi sensu lato in 27 (8 Borrelia afzelii, 7 Borrelia garinii, 8 Borrelia lusitaniae, 3 Borrelia valaisiana and 1 B. burgdorferi sensu stricto). CONCLUSION: B. miyamotoi should be considered in the differential diagnoses of patients with confirmed or suspected tick-bite in Spanish endemic areas for Lyme disease. PMID- 29187293 TI - Immune reconstitution inflammatory syndrome in HIV-infected patients with Pneumocystis jirovecii pneumonia. AB - INTRODUCTION: The incidence of immune reconstitution inflammatory syndrome (IRIS) in HIV-infected patients after an episode of Pneumocystis jirovecii pneumonia (PJP) seems to be lower than with other opportunistic infections. We conducted an observational study in order to determine the incidence, clinical characteristics and outcome of patients diagnosed with PJP-related IRIS. METHODS: We conducted an observational study of HIV patients diagnosed with PJP-related IRIS from January 2000 to November 2015. We analyzed epidemiological and clinical characteristics as well as laboratory findings. We also carried out a systematic review of published cases. RESULTS: Six cases of IRIS out of 123 (4.9%) HIV-infected patients with PJP who started ART were diagnosed. All six cases were men with a median age of 34 (IQR: 8) years. The six patients developed paradoxical IRIS. Subjects younger than 40 years old (p=0.084) and with an HIV-RNA viral load >100000 copies/ml (p=0.081) at diagnosis showed a tendency to develop IRIS. Thirty-seven published cases of PJP-related IRIS were identified. Although 51% of cases involved respiratory failure, no deaths were reported. CONCLUSIONS: PJP related IRIS is rare condition compared to other opportunistic infections. It can lead to a severe respiratory failure in a significant proportion of cases, although no deaths have been reported. PMID- 29187294 TI - Nutrient uptake of the uterus during the last third of pregnancy in sows: Effects of litter size, gestation stage and maternal glycemia. AB - Effects of litter size, pregnancy stage, and glycemia level on uterine uptake of energetic nutrients were studied on multiparous sows left intact (CTR; n=6) or subjected to unilateral oviduct ligation (LIG; n=6). A jugular vein, a carotid artery, and the main vein draining one uterine horn were catheterized. A blood flow probe was fitted around the artery irrigating that horn. A meal test and two glucose infusion tests (1.15 or 2.30g glucose.(100kg BW)-1min-1) were performed at 79, 93, and 106 d of pregnancy. Number of fetuses in the measured uterine horn was lower (3.7 vs. 8.0, P<0.001) and newborn piglets were heavier (1.71 vs. 1.31kg, P=0.04) in the LIG than in the CTR sows. Treatment did not affect uterine blood flow (UBF), but UBF/fetus was greater for the LIG treatment (0.57 vs. 0.32L/min, P=0.003). Glucose and lactate uterine uptakes were never significantly affected by treatment. During both tests, uterine uptake of glucose/fetus was greater in the LIG sows, which was associated with greater growth rate of their fetuses. Glucose and lactate uterine uptakes per fetus increased with glucose infusion level (P=0.03) and stage of pregnancy (P=0.04). Extraction coefficient of glucose decreased during infusion (P<0.001). Uptakes of NEFA and triglycerides were small and decreased during hyperglycemia. Glucose and lactate uptakes increased with pregnancy stage due to increased uterine blood flow. Altogether, the nutrient uptake per fetus was greater in the sows with few fetuses. PMID- 29187295 TI - Comparing Videostroboscopy and Direct Microlaryngoscopy: An Argument for Flexible Consent and Operative Plan. AB - INTRODUCTION: Office-based evaluation of glottic lesions has progressed significantly, but there can still be discrepancies compared with direct microlaryngoscopy (DML) in the operating room. We performed a prospective evaluation comparing diagnosis of epithelial and lamina propria glottic lesions on rigid telescopic strobovideolaryngoscopy (RTS) with DML. METHODS: Fifty subjects were enrolled and underwent RTS followed by DML. We compared presence and extent (unilateral or bilateral) of lamina propria and epithelial lesions. Primary (diagnoses motivating an operation) and secondary (diagnoses not requiring an operation) were considered. Changes in diagnosis and operative plan based on DML findings were evaluated. RESULTS: Sixty-eight lesions were identified on RTS, including 53 primary (15 epithelial, 38 lamina propria) and 15 secondary diagnoses. RTS was accurate in only 36% of subjects. Ten subjects had a different primary pathology identified on DML. A change in surgical management occurred in 16% of subjects. CONCLUSIONS: This is the first prospective study evaluating how both diagnosis and operative plan for epithelial and lamina propria glottic lesions differ based on RTS and DML. Despite significant advances in office-based diagnosis of glottic lesions, there are still notable limitations. Clinicians should consider these findings when counseling patients on interpretation and plan for findings based on RTS. Obtaining a flexible surgical consent and counseling patients on the potential for new diagnoses and interventions based on DML is warranted. PMID- 29187296 TI - Gas adsorption properties of hybrid graphene-MOF materials. AB - Nowadays, hybrid porous materials consisting of metal-organic frameworks (MOFs) and graphene nanosheets become more and more attractive because of their growing applications in adsorption, catalysis and related areas. Incorporation of graphene oxide into MOFs can provide benefits such as increased water resistance and thermal stability as well as enhanced surface area and adsorption properties. Graphene oxide is one of the best additives to other materials owing to its two main virtues: high atomic density and large amount of surface functional groups. Due to its dense array of atoms, graphene oxide can significantly increase dispersion forces in graphene-MOF materials, which is beneficial for adsorption of small molecules. This work presents a concise appraisal of adsorption properties of MOFs and graphene-MOF hybrids toward CO2, volatile organic compounds, hydrogen and methane. It shows that the graphene-MOF materials represent an important class of materials with potential applications in adsorption and catalysis. A special emphasis of this article is placed on their adsorption applications for gas capture and storage. A large number of graphene MOF adsorbents has been so far explored and their appraisal could be beneficial for researchers interested in the development of hybrid adsorbents for adsorption based applications.

AB - AIM: To investigate the anatomical specificity of matrix metalloproteinase-9 (MMP 9) expression in glioblastomas by using voxel-based neuroimaging analysis. MATERIALS AND METHODS: Clinical information and preoperative magnetic resonance images of 133 patients with glioblastomas were reviewed. Evaluation of MMP-9 expression was performed by using immunohistochemistry. Tumour lesions were segmented manually basing on the structural image of each patient, then registered to a standard brain atlas. Voxel-based regression analysis was subsequently performed to identify the specific brain regions that were associated with MMP-9 expression levels. RESULTS: A significantly larger lesion volume of T2-hyperintensity was demonstrated in tumours with low MMP-9 expression compared to those with high MMP-9 expression (p=0.010). No significant difference was found in the lesion volumes of the contrast enhancement areas between the two groups (p=0.452). The major correlated cluster with high MMP-9 expression was identified in the right frontal lobe, while a cluster located at the posterior region of the right lateral ventricle was correlated with low MMP-9 expression. CONCLUSION: Voxel-based statistical analysis revealed the anatomical specificity of MMP-9 expression levels in glioblastoma. The identified correlation between molecular biomarkers and anatomical distribution may increase our understanding of the biological characteristics of glioblastoma and provide new insight into the molecular subtypes of glioblastoma. PMID- 29187299 TI - Diagnostic decision support systems for atrial fibrillation based on a novel electrocardiogram approach. AB - BACKGROUND: The electrocardiogram (ECG) is one of the most non-invasive techniques to give support to the atrial fibrillation (AF) diagnosis. Several authors use the temporal difference between two consecutive R waves, a method known as RR interval, to perform the AF diagnosis. However, RR interval-based analysis does not detect distortions on the other ECG waves. PURPOSE: Thus, the present work proposes a diagnostic decision support systems for AF based on higher order spectrum analysis of the voltage variation on the ECG.. METHODS: The proposed method was used aiming AF classifying. The classifier is composed by two screening stages: one based on the average and another on the average deviation of kurtosis of the ECG signals. Heartbeat obtained from the MIT-BIH atrial fibrillation and MIT-BIH normal were used. RESULTS: ECG signal featured by kurtosis outperforms second order statistics based metrics in up to 476 times, and up to 110 times above the RR interval. The screening methods obtained sensitivity equal to 100% and specificity is up to 84.04%. The two screening methods combined provided an AF classifier with an accuracy rate at diagnosis of 100%. The results presented take into account windows of up to five heartbeats and a 99.73% confidence interval. CONCLUSION: The results obtained by the proposed method can be used to support decision-making in clinical practices with a diagnostic accuracy rate of 90.04% to 100%. PMID- 29187301 TI - Teacher?

AB - BACKGROUND & AIMS: Although parenteral nutrition (PN) is often used after allogeneic hematopoietic stem cell transplantation (allo-HSCT), there is controversy regarding PN management, for instance in the use of fat emulsion and glucose control (GC). To clarify these issues, we conducted a multi-center prospective study with intensive GC, randomizing the use of fat emulsion after allo-HSCT using a myeloablative conditioning regimen. METHODS: The primary endpoint was the cumulative incidence of documented infectious disease, namely bacterial and fungal infection, at day 100 after allo-HSCT. Between August 2007 and March 2012, we enrolled 81 patients at 5 centers. Excluding 5 ineligible patients, 76 patients received the protocol treatment. The target fasting glucose level was 80-110 mg/dL. RESULTS: The median follow-up of surviving patients was 1796 days. The cumulative incidences of documented infectious disease at day 100 were 16% (95% confidence interval [CI] 6-29%) in the no-fat group and 19% (95% CI 8-32%) in the fat group, indicating no significant difference. The mean glucose level at 28 days after allo-HSCT was 107 mg/dL in the no-fat group and 111 mg/dL in the fat group. Grade 3 hyperglycemia (>250 mg/dL) and grade 3 hypoglycemia (<40 mg/dL) occurred in 4 patients each (5.3%). Overall survival and non-relapse mortality rates at 4 years were 75% and 11% in the no-fat group and 69% and 8% in the fat group, respectively. CONCLUSIONS: Irrespective of the use of fat emulsion, the long-term clinical outcomes of the enrolled patients were favorable under intensive GC. To further clarify the benefits of GC after allo-HSCT, a prospective study randomizing the level of GC is warranted. PMID- 29187303 TI - Prevalence and characteristics of chronic kidney disease among Danish adults with cystic fibrosis. AB - BACKGROUND: With improved prognosis of CF, comorbidities including chronic kidney disease (CKD) are becoming increasingly important. Identification of those at highest CKD risk is hence a priority. METHODS: In this cross-sectional study, adults with CF attending the Copenhagen CF Centre at Rigshospitalet with >=2 measurements of serum creatinine from 2013 to 2015 were included. Data was obtained from an electronic CF database, which contains anonymised clinical and laboratory data on all individuals attending the clinic. CKD was defined as a confirmed (>=3months apart) estimated glomerular filtration rate<=60mL/min/1.73m2. RESULTS: Of 181 individuals, the CKD prevalence was 2.7% and increased to 11% after inclusion of lung transplanted patients. Individuals with CKD were generally older (median 39 (IQR, 36-45) vs. 31 (IQR, 24-39) years; p<0.001), diabetic (86% vs. 41%, p<0.001), with longer median duration of chronic pulmonary infection (28.3 (20.0-35.8) vs. 20.0 (9.9-34.7) years; p=0.008) and with longer intravenous aminoglycosides use (606 (IQR, 455-917) vs. 273 (IQR, 91 826) days, p=0.005). CONCLUSIONS: The CKD prevalence is high and related to age, diabetes, chronic infection, transplantation and aminoglycosides use. These observations call for longitudinal studies investigating CKD predictors in adults with CF.

AB - OBJECTIVE: To examine Supplemental Nutrition Assistance Program (SNAP) recipients' use of the first online supermarket accepting Electronic Benefit Transfer (EBT) payment. METHODS: In this mixed-methods study, the authors collected EBT purchase data from an online grocer and attempted a randomized controlled trial in the South Bronx, New York City, followed by focus groups with SNAP beneficiaries aged >=18 years. Participants were randomized to shop at their usual grocery store or an online supermarket for 3 months. Focus groups explored barriers and motivators to online EBT redemption. RESULTS: Few participants made online purchases, even when incentivized in the randomized controlled trial. Qualitative findings highlighted a lack of perceived control over the online food selection process as a key barrier to purchasing food online. Motivators included fast, free shipping and discounts. CONCLUSIONS AND IMPLICATIONS: Electronic Benefit Transfer for online grocery purchases has the potential to increase food access among SNAP beneficiaries, but challenges exist to this new food buying option. Understanding online food shopping barriers and motivators is critical to the success of policies targeting the online expansion of SNAP benefits. PMID- 29187305 TI - Liver resection for colorectal cancer metastases: a comparison of outcomes over time in South Australia. AB - BACKGROUND: The aim of the current study was to assess outcomes following liver resection in metastatic CRC (mCRC) in South Australia across two study periods (pre-2006 versus post-2006). METHODS: The South Australian (SA) Clinical Registry for mCRC maintains data prospectively on all patients in SA with mCRC diagnosed from 01 February 2006. This data was linked with a prospectively collated database on liver resections for mCRC from 01/01/1992 to 01/02/2006. The primary end point was overall survival. RESULTS: 757 patients underwent liver resection for mCRC. Liver resection was performed on 286 patients pre-2006 and 471 patients post-2006. The median age of the study population was 62 years, and this was similar across both eras. Overall survival was significantly better in the post 2006 era (hazard ratio HR = 0.45, p = 0.001). Complications (59% pre-2006 versus 23% post-2006) and transfusion rates (34% pre-2006 versus 2% post-2006) were significantly higher in the pre-2006 era. Repeat liver resection rates were significantly higher in the post-2006 era (1% pre-2006 versus 10% post-2006). CONCLUSIONS: Outcomes following liver resection for mCRC have improved over time, with significantly better overall survival in the post-2006 era compared to pre 2006. PMID- 29187306 TI - Contribution of Load Expectations to Neuromechanical Adaptations During a Freestyle Lifting Task: A Pilot Study. AB - OBJECTIVES: The main goal of this study was to determine to what extent load expectations modulate neuromechanical adaptations in individuals with and without chronic low back pain (cLBP) when lifting and lowering various loads. The second goal was to assess the feasibility of a simple lifting protocol during which expectations about loads were manipulated. METHODS: Seventeen participants with cLBP and 18 participants without low back pain were asked to lift and lower boxes of mild to moderate loads. Two kinds of expectations (lighter and heavier) were respectively associated to each experimental block. Self-reported exertion was assessed to control for expectations modulation. Erector spinae and vastus lateralis electromyography (EMG) activity were recorded and kinematics angle calculated. RESULTS: The results showed a main effect of expectations, with loads introduced as heavier being associated to a higher exertion compared with loads introduced as lighter. EMG activity analyses revealed significant interaction involving expectations, movement phase, and loads, as well as significant differences between groups. Kinematic angles did not reveal any significant effect of expectations nor group during the lifting phase. CONCLUSIONS: Psychological factors may contribute to neuromechanical adaptations to low back pain. Our preliminary findings show that expectations about loads may result in neuromechanical differences between individuals with cLBP and those without cLBP. This pilot study showed that testing the manipulation of expectations and EMG records was feasible but highlighted the need to go beyond single infrared markers to assess kinematics. PMID- 29187307 TI - Evaluation of Cross-Cultural Adaptation and Measurement Properties of STarT Back Screening Tool: A Systematic Review. AB - OBJECTIVE: The purpose of this systematic review was to investigate the extent to which the STarT Back Screening Tool (SBST) has been evaluated for (1) the quality of translation of evidence for cross-cultural adaptation and (2) the measurement properties in languages other than English. METHODS: A systematic search of 8 databases, including Medline, Embase, CINAHL, PsycINFO, AMED, Scopus, PubMed, and Web of Science, was performed. Electronic databases were searched for the period between 2008 and December 27, 2016. We included studies related to cross-cultural adaptation, including translation and assessment of the measurement properties of SBST. Study selection, translation, methodologic and quality assessments, and data extraction were performed independently by 2 reviewers. RESULTS: Of the 1566 citations retrieved, 17 studies were admissible, representing 11 different SBST versions in 10 languages. The quadratic weighted kappa statistics of the 2 reviewers, for the translation, methodologic assessment, and quality assessment were 0.85, 0.76, and 0.83, respectively. For translation, only 2 versions (Belgian-French and Mandarin) fulfilled all requirements. None of the versions had tested all the measurement properties, and when performed, these were found to have been conducted inadequately. With regard to quality assessment, overall, the included versions had a "Poor" total summary score except 2 (Persian and Swiss-German), which were rated as "Fair." CONCLUSIONS: Few versions fully met the standard criteria for valid translation, and none of the versions tested all the measurement properties. There is a clear need for more accurate cross cultural adaptation of SBST and greater attention to the quality of psychometric evaluation of the adapted versions of SBST. At this time, caution is recommended when using SBST in languages other than English. PMID- 29187308 TI - Chiropractic Management for US Female Veterans With Low Back Pain: A Retrospective Study of Clinical Outcomes. AB - OBJECTIVE: The purpose of this study was to determine if female US veterans had clinically significant improvement in low back pain after chiropractic management. METHODS: This is a retrospective chart review of 70 courses of care for female veterans with a chief complaint of low back pain who received chiropractic management through the VA Western New York Healthcare System in Buffalo, New York. A paired t test was used to compare baseline and discharge outcomes for the Back Bournemouth Questionnaire. The minimum clinically important difference was set as a 30% improvement in the outcome measure from baseline to discharge. RESULTS: The average patient was 44.8 years old, overweight (body mass index 29.1 kg/m2), and white (86%). The mean number of chiropractic treatments was 7.9. Statistical significance was found for the Back Bournemouth Questionnaire outcomes. The mean raw score improvement was 12.4 points (P < .001), representing a 27.3% change from baseline with 47% of courses of care meeting or exceeding the minimum clinically important difference. CONCLUSION: For our sample of female veterans with low back pain, clinical outcomes from baseline to discharge improved under chiropractic care. Although further research is warranted, chiropractic care may be of value in contributing to the pain management needs of this unique patient population. PMID- 29187309 TI - A Finite Element Analysis of Stress Distribution and Disk Displacement in Response to Lumbar Rotation Manipulation in the Sitting and Side-Lying Positions. AB - OBJECTIVE: This study aimed to investigate stress distribution and disk displacement in healthy and degenerated intervertebral disks during simulated lumbar rotation manipulation (LRM) in the sitting and side-lying positions. METHODS: Three-dimensional (3D) finite element models of healthy, mildly degenerated and moderately degenerated L4/5 spinal units were reconstructed. Lumbar rotation manipulation in the sitting and side-lying positions were simulated, and alterations in stress distribution and disk displacement in the lumbar disks were observed. RESULTS: The application of LRM in the sitting or side-lying position resulted in a similar stress distribution in healthy, mildly degenerated, and moderately degenerated disks. Stress was concentrated at the anterior right side of the annulus. In all disks, intradiskal pressure (IDP) and maximum von Mises stress were higher during LRM in the sitting position than during LRM in the side-lying position. During these manipulations, Intradiskal pressure and stress in the annulus of moderately degenerated disks were higher than in mildly degenerated disks. Displacement was most obvious in healthy disks. CONCLUSIONS: Mildly and moderately degenerated lumbar disks were subject to higher stress during LRM in the sitting position than during LRM in the side lying position. Intradiskal pressure and the maximum von Mises stress in the annulus of moderately degenerated disks increased, suggesting the need for caution when treating patients with moderately compromised disks. Although our results are in accordance with previously published data, they are simulated and preliminary and do not necessarily replicate the clinical condition. PMID- 29187310 TI - Changes in Lower Limb Strength and Function Following Lumbar Spinal Mobilization. AB - OBJECTIVE: The purpose of this study was to investigate whether grade III passive lumbar rotational mobilization on L2-3 can improve hip flexor strength and performance in the single-leg triple-hop test in asymptomatic young adults. METHODS: Twenty-four participants (12 men, 12 women) aged from 19 to 26 years who were positive in the hip flexor "break" test were recruited in this study. They were randomly allocated to the treatment group or sham group. Isometric hip flexor torque (N.m) and single-leg triple-hop distance (cm) were measured before and after a passive lumbar rotational mobilization or a sham intervention. RESULTS: After the intervention, both the treatment and sham groups exhibited a significant increase in longest hop distance (P = .040 and .044, respectively). The treatment group had a significantly higher (3.41 +/- 5.44%) positive percentage change in torque than the sham group (-2.36 +/- 5.81%) (P = .02). CONCLUSION: The study results indicated a potential effect of grade III passive lumbar rotational mobilization in improving hip flexor strength. However, whether the improvement in hopping performance was the result of a treatment effect or a learning effect could not be determined. PMID- 29187311 TI - Intrarater and Inter-rater Reliability of Active Cervical Range of Motion in Patients With Nonspecific Neck Pain Measured With Technological and Common Use Devices: A Systematic Review With Meta-regression. AB - OBJECTIVES: The purpose of this systematic review was to compare intrarater and inter-rater reliability of active cervical range of motion (ACROM) measures obtained with technological devices to those assessed with low-cost devices in patients with nonspecific neck pain. As a secondary outcome, we investigated if ACROM reliability is influenced by the plane of the assessed movement. METHODS: Medline, Scopus, Embase, the Cochrane Library, CINHAL, PEDro, and gray literature were searched until August 2016. Inclusion criteria were reliability design, population of adults with nonspecific neck pain, examiners of any level of experience, measures repeated at least twice, and statistical indexes on reliability. A device was considered inexpensive if it cost less than ?500. The risk of bias of included studies was assessed by Quality Appraisal of Reliability Studies. RESULTS: The search yielded 35 151 records. Nine studies met all eligibility criteria. Their Quality Appraisal of Reliability Studies mean score was 3.7 of 11. No significant effect of the type of device (inexpensive vs expensive) on intraclass correlation coefficient (ICC) was identified for intrarater (ICC = 0.93 vs 0.91; P > .99) and inter-rater reliability (ICC = 0.80 vs 0.87; P > .99). The plane of movement did not affect inter-rater reliability (P = .11). Significant influences were identified with intrarater reliability (P = .0001) of inexpensive devices, where intrarater reliability decreased (P = .01) in side bending, compared with flexion-extension. CONCLUSIONS: The use of expensive devices to measure ACROM in adults with nonspecific neck pain does not seem to improve the reliability of the assessment. Side bending had a lower level of intrarater reliability. PMID- 29187312 TI - Comparison of Pressure Pain Thresholds in Upper Trapezius and Temporalis Muscles Trigger Points Between Tension Type Headache and Healthy Participants: A Case Control Study. AB - OBJECTIVE: To date, the minimum clinical differences (MCDs) in the pressure pain thresholds (PPTs) of the upper trapezius and temporalis muscles have not yet been established in participants with tension-type headache (TTH). The purpose of the study was to evaluate the MCDs of the PPTs of the upper trapezius and temporalis in participants with TTH and those without TTH. METHODS: The sample comprised 120 participants with TTH (n = 60; mean [standard deviation] years = 38.30 [10.05]) and without TTH (n = 60; 34 [8.20]). The participants were recruited from an outpatient clinic in Spain from 2014 to 2016. The PPTs of the most hyperalgesic trigger points of the upper trapezius and temporalis were assessed. RESULTS: There were statistically significant differences, mean (standard deviation) kg/cm2, for the right upper trapezius PPT (P < .001; 1.52 [0.35] vs 2.37 [0.49]), the left upper trapezius PPT (P < .001; 1.53 [0.36] vs 2.29 [0.49]), the right temporalis PPT (P = .008; 1.56 [0.31] vs 1.72 [0.33]), and the left temporalis PPT (P = .001; 1.57 [0.27] vs 1.74 [0.30]) between participants with and without TTH, respectively. CONCLUSIONS: The PPT MCDs for the right and left upper trapezius and the right and left temporalis were 0.85, 0.76, 0.16, and 0.17 kg/cm2, respectively, for the clinical management of trigger points in participants with TTH. PMID- 29187313 TI - Immediate Changes in Resting and Contracted Thickness of Transversus Abdominis After Dry Needling of Lumbar Multifidus in Healthy Participants: A Randomized Controlled Crossover Trial. AB - OBJECTIVE: The purpose of this study was to investigate changes in resting and/or contraction thickness of the transversus abdominis (TrA) muscle after dry needling (DN) of the lumbar multifidus (LM) in asymptomatic participants. METHODS: A randomized controlled laboratory trial with crossover design was performed. Forty-seven healthy individuals who had not experienced low back pain in the previous 6 months were randomly assigned to receive DN to the LM or a sham DN intervention. Participants received both interventions separated at least 7 days apart. They were instructed on how to perform a concentric contraction of TrA. Resting and contraction thicknesses of the TrA were obtained through real time ultrasound measurements before and immediately after each intervention by an assessor blinded to the intervention received. Data from 4 individuals had to be excluded because of poor image quality. RESULTS: Two-way analysis of variance revealed a significant contraction with treatment interaction (F[1,42] = 11.489; P = .002). Simple main effects using paired-samples t tests and a Bonferroni post hoc analysis revealed differences in contracted states of the TrA for DN vs sham DN (P = .009) and between contracted and resting states for the DN group (P = .001): after DN, TrA thickness at rest exhibited a mean decrease of 0.03 cm and a mean increase of 0.05 cm during contraction. CONCLUSION: This study suggests that application of DN to LM was accompanied by a decreased resting thickness and an increased contraction thickness of the TrA in asymptomatic participants. PMID- 29187314 TI - What is stressful for females? Differential effects of unpredictable environmental or social stress in CD1 female mice. AB - Stressful life events are a major factor in the etiology of several diseases, such as cardiovascular, inflammatory and psychiatric disorders (i.e., depression and anxiety), with the two sexes greatly differing in vulnerability. In humans and other animals, physiological and behavioral responses to stress are strongly dependent on gender, and conditions that are stressful for males are not necessarily stressful for females. Hence the need of an animal model of social chronic stress specifically designed for females. In the present study we aimed to compare the effects of two different chronic stress procedures in female mice, by investigating the impact of 4weeks of nonsocial unpredictable, physical stress by the Chronic Mild Stress paradigm (CMS; Exp.1) or of Social Instability Stress (SIS; Exp.2) on physiological, endocrine and behavioral parameters in adult female mice. CMS had a pronounced effect on females' response to novelty (i.e., either novel environment or novel social stimulus), body weight growth and hormonal profile. Conversely, 4weeks of social instability did not alter females' response to novelty nor hormonal levels but induced anhedonia. Our findings thus showed that female mice were more sensitive to nonsocial stress due to unpredictable physical environment than to social instability stressors. Neither of these stress paradigms, however, induced a consistent behavioral and physiological stress response in female mice comparable to that induced by chronic stress procedures in male mice, thus confirming the difficulties of developing a robust and validated model of chronic psychosocial stress in female mice. PMID- 29187316 TI - Immunity and Inflammation: From Jekyll to Hyde. AB - The immune system is the defense system of the host that protects it from foreign pathogens. Inflammation is one of the key processes that alert the immune system but when loss of regulation occurs, a long-term chronic inflammation settles and is likely to be detrimental to the host. Most age-related diseases are linked to a disequilibrium of circulating inflammatory molecules. We could use the analogy of "Dr Jekyll' representing the expected inflammation and immune response in general and the "Mr. Hyde" effect represented by the other face of inflammation, when it is dysregulated. This review aims to cover how immunity, inflammation and persistent infection are associated and some aspects that future studies should look into such as tissue-specific immunity and interventions. Having this knowledge will enable us to prevent inflammation to lose its regulatory network, which could potentially increase the health-span and a better quality of life for the growing elderly population. PMID- 29187315 TI - Molecular characterization of a human G20P[28] rotavirus a strain with multiple genes related to bat rotaviruses. AB - Group A rotaviruses are the major cause of severe gastroenteritis in the young of mammals and birds. This report describes characterization of an unusual G20P[28] rotavirus strain detected in a 24month old child from Suriname. Genomic sequence analyses revealed that the genotype constellation of the Suriname strain RVA/Human-wt/SUR/2014735512/2013/G20P[28] was G20-P[28]-I13-R13-C13-M12-A23-N13 T15-E20-H15. Genes VP1, VP2, VP3, NSP1, NSP2, NSP3, NSP4 and NSP5 were recently assigned novel genotypes by the Rotavirus Classification Working Group (RCWG). Three of the 11 gene segments (VP7, VP4, VP6) were similar to cognate gene sequences of bat-like human rotavirus strain Ecu534 from Ecuador and the VP7, NSP3 and NSP5 gene segments of strain RVA/Human-wt/SUR/2014735512/2013/G20P[28] were found to be closely related to gene sequences of bat rotavirus strain 3081/BRA detected in Brazil. Although distantly related, the VP1 gene of the study strain and bat strain BatLi09 detected in Cameroon in 2014 are monophyletic. The NSP1 gene was found to be most closely related to human strain QUI-35-F5 from Brazil. These findings suggest that strain RVA/Human wt/SUR/2014735512/2013/G20P[28] represents a zoonotic infection from a bat host. PMID- 29187317 TI - Establishing ultrasound based transient elastography cutoffs for different stages of hepatic fibrosis and cirrhosis in Egyptian chronic hepatitis C patients. AB - BACKGROUND AND STUDY AIM: Transient elastography is widely used to assess fibrosis stage in chronic hepatitis C (CHC). We aimed to establish and validate different transient elastography cut-off values for significant fibrosis and cirrhosis in CHC genotype 4 patients. PATIENTS AND METHODS: The data of 100 treatment-naive CHC patients (training set) and 652 patients (validation set) were analysed. The patients were subjected to routine pretreatment laboratory investigations, liver biopsy and histopathological staging of hepatic fibrosis according to the METAVIR scoring system. Transient elastography was performed before and in the same week as liver biopsy using FibroScan (Echosens, Paris, France). Transient elastography results were correlated to different stages of hepatic fibrosis in both the training and validation sets. RESULTS: ROC curves were constructed. In the training set, the best transient elastography cut-off values for significant hepatic fibrosis (>=F2 METAVIR), advanced hepatic fibrosis (>=F3 METAVIR) and cirrhosis (F4 METAVIR) were 7.1, 9 and 12.2 kPa, with sensitivities of 87%, 87.5% and 90.9% and specificities of 100%, 99.9% and 99.9%, respectively. The application of these cut-offs in the validation set showed sensitivities of 85.5%, 82.8% and 92% and specificities of 86%, 89.4% and 99.01% for significant hepatic fibrosis, advanced hepatic fibrosis and cirrhosis, respectively. CONCLUSION: Transient elastography performs well for significant hepatic fibrosis, advanced hepatic fibrosis and cirrhosis, with validated cut offs of 7.1, 9 and 12.2 kPa, respectively, in genotype 4 CHC patients. PMID- 29187319 TI - Ethnoveterinary botanical survey of medicinal plants in Abergelle, Sekota and Lalibela districts of Amhara region, Northern Ethiopia. AB - ETHNOPHARMACOLOGICAL RELEVANCE: The study area is known by its huge livestock resources with extensive ethnoveterinary practice. This knowledge was not documented scientifically until we proposed to do so. The study can aid in future planning of endangered species conservation as well as for experimental studies in search of modern pharmacotherapy. AIM OF THE STUDY: The study objective was to understand the extent of ethnoveterinary practice, methods, types of medicinal plant species used and to generate a comprehensive baseline data that can be used as a basis for further studies. MATERIALS AND METHODS: The survey was conducted from November 2015 to December 2016 in different seasons of the year. Participant selection process was started by recording all the known animal healers by assigning village leaders, animal health professionals, and research field assistants to record all animal healers of the area. Assigned personals communicate elders, and other members of the communities of the 3 districts to recommend the traditional animal healer they know. Accordingly, 60 participants were recommended by the peoples of the 3 districts and the interview process was conducted with a semi-structured questionnaire to record the knowledge of ethnoveterinary practice of the 60 healers. After finishing the interview process, researchers had a walk in the woods, mountains, and rivers with informants to collect medicinal plants. Standard procedures were followed for the record of plant materials, drying, and pressing of plant specimens was performed in the field followed by labeling with the local name, collection date, collection site, and identification code. RESULTS: A total of 53 medicinal plants that belong to 31 families used in treating 22 kinds of livestock diseases were identified. CONCLUSION: We found the area has a huge resource of ethnoveterinary medicinal plants. However, overuse and environmental anthropological change resulted in the scarcity of medicinal plants. This condition was complained by healers during the survey. PMID- 29187318 TI - Instructing children with Autism Spectrum Disorder: Examining swim instructors' knowledge building experiences. AB - BACKGROUND: Although there has been a notable increase in Autism Spectrum Disorder (ASD) diagnoses over the past twenty years, children with ASD continue to be underrepresented in physical activity opportunities. Swimming lessons have been suggested as an ideal form of physical activity for this population, but studies exploring instructors' experiences gaining knowledge specific for instructing these swimmers remains limited. Research in this area is warranted, as drowning is a leading injury cause of death for persons with ASD. OBJECTIVE: The purpose of this brief report was to examine swim instructors' preferred knowledge sources for building their individual swimming lessons, catered to swimmers with ASD. Moreover, this study aimed to provide context specific insights for instructors and instructor educators to increase new and future instructors' preparedness for meeting the needs of this population. METHODS: Three recreational swim instructors were recruited for this qualitative study. Data were collected using a demographic questionnaire, observations, and semi structured interviews. Analysis was completed using Braun & Clarke's guide for thematic analysis. RESULTS: The results indicated that swim instructors' sources for building knowledge included: learning from peers/mentors, receiving support from parents/caregivers, and participating in additional certification programs or training. CONCLUSION: With a more extensive understanding of instructors' knowledge building experiences, instructor educators may integrate this knowledge into future development programs to prepare a greater number of trained individuals to facilitate physical activities for children with ASD. PMID- 29187320 TI - Progressive practice promotes motor learning and repeated transient increases in corticospinal excitability across multiple days. AB - BACKGROUND: A session of motor skill learning is accompanied by transient increases in corticospinal excitability(CSE), which are thought to reflect acute changes in neuronal connectivity associated with improvements in sensorimotor performance. Factors influencing changes in excitability and motor skill with continued practice remain however to be elucidated. OBJECTIVE/HYPOTHESIS: Here we investigate the hypothesis that progressive motor practice during consecutive days can induce repeated transient increases in corticospinal excitability and promote motor skill learning. METHODS: Changes in motor performance and CSE were assessed during 4 consecutive days of skill learning and 8 days after the last practice session. CSE was assessed as area under recruitment curves(RC) using transcranial magnetic stimulation(TMS). Two groups of participants(n = 12) practiced a visuomotor tracking-task with task difficulty progressively increased with individual proficiency(PPG) or with the same task level throughout all 4 days(NPPG). RESULTS: Progressive practice resulted in superior motor learning compared to NPPG(p < 0.001). Whereas NPPG displayed increased CSE following only the first day of practice(p < 0.001), progressive motor practice was accompanied by increases in CSE on both the first and the final session of motor practice(p = 0.006). Eight days after ended practice, the groups showed similar CSE, but PPG maintained superior performance at a skilled task level and transfer task performance(p < 0.005,p = 0.029). CONCLUSION: The results demonstrate that progressive practice promotes both motor learning and repeated increases in CSE across multiple days. While changes in CSE did not relate to learning our results suggest that they signify successful training. Progressive practice is thus important for optimizing neurorehabilitation and motor practice protocols in general. PMID- 29187321 TI - Impaired neurogenesis and associated gliosis in mouse brain with PEX13 deficiency. AB - Zellweger syndrome (ZS), a neonatal lethal disorder arising from defective peroxisome biogenesis, features profound neuroanatomical abnormalities and brain dysfunction. Here we used mice with brain-restricted inactivation of the peroxisome biogenesis gene PEX13 to model the pathophysiological features of ZS, and determine the impact of peroxisome dysfunction on neurogenesis and cell maturation in ZS. In the embryonic and postnatal PEX13 mutant brain, we demonstrate key regions with altered brain anatomy, including enlarged lateral ventricles and aberrant cortical, hippocampal and hypothalamic organization. To characterize the underlying mechanisms, we show a significant reduction in proliferation, migration, differentiation, and maturation of neural progenitors in embryonic E12.5 through to P3 animals. An increasing reactive gliosis in the PEX13 mutant brain started at E14.5 in association with the pathology. Together with impaired neurogenesis and associated gliosis, our data demonstrate increased cell death contributing to the hallmark brain anatomy of ZS. We provide unique data where impaired neurogenesis and migration are shown as critical events underlying the neuropathology and altered brain function of mice with peroxisome deficiency. PMID- 29187323 TI - The prescription at the elder person: a difficult art. PMID- 29187324 TI - Pain in the elderly and cognition: state of play. AB - Cognitive impairment is commonly associated with the pain experience. This deterioration regarding several cognitive domains such as attention, speed of information processing, memory, learning and executive functions, represents a major obstacle to daily activities and mobility especially in the elderly for whom a decrease in mobility is a significant risk factor for death and disability. Regarding the demographic rising in the elderly population expected by 2050 (the proportion of persons aged 60 and above is expected to double according to ONU estimate) and the high prevalence of pain in this age reaching 80% in nursing homes, clinicians should be better aware of the links between pain and cognition in this population's segment so that they offer each patient an appropriate treatment. The objective of this review is to draw up an inventory of knowledge and differences between general population and elderly population on the complex relationship between these two phenomena, the contribution of imaging in the understanding of this link and the role of attitudes, beliefs and opioids on pain perception and cognition. PMID- 29187322 TI - Sanitary Sewer Overflows and Emergency Room Visits for Gastrointestinal Illness: Analysis of Massachusetts Data, 2006-2007. AB - BACKGROUND: Sanitary sewer overflows (SSOs) occur when untreated sewage is discharged into water sources before reaching the treatment facility, potentially contaminating the water source with gastrointestinal pathogens. OBJECTIVES: The objective of this paper is to assess associations between SSO events and rates of gastrointestinal (GI) illness in Massachusetts. METHODS: A case-crossover study design was used to investigate association between SSO events and emergency room (ER) visits with a primary diagnosis of gastrointestinal (GI) illness in Massachusetts for 2006-2007. ER visits for GI were considered exposed if an SSO event occurred in the county of residence within three hazard periods, 0-4 d, 5-9 d, or 10-14 d, before the visit. A time-stratified bidirectional design was used to select control days for each ER visit on the same day of the week during the same month. Fixed effect logistic regression models were used to estimate the risk of ER visits following the SSO event. RESULTS: During the study period, there were 270 SSO events for northeastern Massachusetts and 66,460 ER admissions with GI illness listed as the primary diagnostic code. The overall odds ratio (OR) for ER visits for GI illness was 1.09 [95% confidence interval (CI): 1.03, 1.16] in the 10-14 d period following an SSO event, with positive ORs for all age groups and for three of the four counties. The 0-4 d and 5-9 d periods following an SSO event were not associated with ER visits for GI illness overall, and associations by county or age were inconsistent. CONCLUSIONS: We demonstrated an association between SSO events and ER visits for GI illness using a case crossover study design. In light of the aging water infrastructure in the United States and the expected increase in heavy rainfall events, our findings suggest a potential health impact associated with sewage overflows. https://doi.org/10.1289/EHP2048. PMID- 29187325 TI - Relevance of G8 scale in referring elderly patients with aortic stenosis requiring a TAVI for a geriatric consultation. AB - Aortic stenosis (AS) may soon become a significant public health issue. Referring elderly suffering from aortic stenosis for a transcatheter aortic valve implantation (TAVI) versus surgical valve replacement might be difficult and requires a multidisciplinary staff. G8 is a geriatric screening scale for frailty, validated in oncogeriatry. We study sensibility and specificity of G8 used by cardiologists in comparison to a comprehensive geriatric assessment (CGA) performed by geriatrician. Prospective study, from February to July 2015, in Bordeaux university Hospital, France. Every elderly admitted for a TAVI had a G8 scale performed by cardiologist and CGA by a geriatrician in blind. Comorbidities were assessed using Cumulative Illness Rating Scale in his geriatric version (CIRS-G). CGA was abnormal if: MMSE <24/30 or GDS >=7/15 or ADL <=5/6 or IADL <=7/8 or TUG >=20 seconds or if malnutrition was noticed. G8 was abnormal if <=14/17. We calculated sensibility, specificity, positive and negative predictive value in comparison to gold-standard CGA. 49 patients were included (55.1% women, mean age 84.8 years old). Nearly half of the patients (48.96%) had multiple comorbidities (CIRS G score >3 for at least three items excluding the cardiology item). 38 CGA were abnormal (77.55%) and 41 G8 (83.67%). G8 had a sensibility of 100% (IC 95% [0.9-1]), a specificity of 72.7% (IC 95% [0.43-0.9]), a positive predictive value of 92.6% and a negative prospective value of 100% (IC: 95%). G8 scale seems to be an efficient geriatric screening tool for frailty in elderly undergoing TAVI in comparison to CGA. Simple and useful, G8 scale could be performed by cardiologists in older patients with AS for identifying patients with a geriatric risk profile in consultation before surgery. Further studies with bigger samples are needed to confirm these results. PMID- 29187326 TI - Decision making affecting care of older people with cancer: a comparison between general practitioners and oncologists in Lorraine. AB - The main objective of this study is to identify the decision criteria of general practitioners and oncologists in the management of older patients with cancer in Lorraine. The secondary objectives are to identify the difficulties encountered and to propose solutions to improve health path of these patients. 2,995 post mail questionnaires were sent to all general practitioners and oncologists in Lorraine. Some decision criteria differ between general practitioners and oncologists: civilian age and accessibility to a specialized advice for general practitioners; type of cancer, nutritional status, application of best practice recommendations, and multidisciplinary discussion for oncologists. The main difficulties reported are organizational and relate to time interval before specific care beginning, accessibility to a medical specialist, and post diagnosis such link between primary care and hospital. General practitioners and oncologists mainly agree with the difficulties encountered and the solutions to find, even if some decision criteria differences are highlighted. The training of professionals remains the major lever for improvement of medical practices. PMID- 29187327 TI - Endoscopic retrograde cholangiopancreatography in the elderly over 75 years old: a survey. AB - Whilst endoscopic retrograde cholangiopancreatography (ERCP) is being practiced on increasingly older patients, its benefits have not been well studied. This study assessed the clinical benefit of ERCP for subjects aged 75 and over, including follow-up at 3 months of geriatric functional parameters and lifestyle. This is a prospective mono-centric, cohort study. All patients aged 75 and over receiving ERCP were enrolled and monitored for a period of 3 months. We recorded 53 inclusions between November 1st 2014 to 31 May 2015. Our "ill-type" was a fragile polypathology woman of 85 years, living at home, with loss of autonomy for instrumental activities of daily living (IADL). Lithiasis was diagnosed in 56.6% of cases, and malignant stenosis in 35.8% of cases. The success rate was 88.7% with a 5.7% complication rate. At 3 months, we observed no clinically significant change in ADL parameters, IADL and lifestyle. Our follow-up data support the practice of ERCP in geriatric populations. PMID- 29187328 TI - Survey of the prescription of step-2 analgesics in persons aged 75 years and older in general practitioners. AB - Although step-2 analgesics (S2A) are recommended when step-1 analgesics (S1A) are ineffective or in cases of moderate to severe pain, their efficacy varies. This study evaluated the place attributed by general practitioners (GPs) to S2A in the treatment of nociceptive pain in elderly persons (EP). Descriptive, transversal and declarative study conducted among GPs in Burgundy. In total, 115 GPs took part in the survey. Among these, 60.8% had at least one consultation/day for pain. After paracetamol, which was systematically preferred, 56.4% prescribed S2A for EP. The reasons for prescribing S2A included pain not relieved by S1A in 93% of cases, another medical treatment or not (42.6%), or the existence of moderate to severe pain (31.3%). The use of S2A was more frequent in acute pain (79.1%) than in chronic pain (53%). Among GPs, 77.4% initially prescribed the minimal effective dose. GPs were reluctant to prescribe S2As for the following reasons: poor tolerance (78.3%) and the fear of severe adverse effects (57.4%). The most frequently cited adverse effects were nausea/vomiting and constipation by 66.1% of GPs. Nonetheless, 73.9% thought that S2As were necessary for EPs requiring outpatient care. Although the benefit/risk ration of S2As is controversial and their analgesic efficacy seems to be more variable than that of low-dose morphine, they have an important place in the therapeutic arsenal of GPs to treat pain in EP.

AB - : Olders patients are exposed to iatrogenic risk as they are often frail, with multiple pathologies and therefore polymedicated. The objective of this study was to evaluate the knowledge of treatment in the elderly before and after a time of oral therapeutic education accompanied by the submission of a written educational support. The impact of that education on the adhesion was also evaluated. METHODS: We've included patients aged at least 75 years old, living at home, and managing themselves their treatment. At study entry, patients were evaluated by their regular physician about knowledge and compliance of their treatment and were receiving therapeutic education time. Three months later, knowledge and adherence to treatment were re-evaluated by the treating physician during an interview. The adhesion was evaluated using the Morisky score. RESULTS: 89 subjects were enrolled between May and October 2015. The average age was 81.9 years old and most patients were autonomous. We observed an improvement in the knowledge three months after the intervention (drug names: 67% vs 76%, p=0.048; indications: 80% vs 91%, p=0.010; dosages: 83% vs 92%, p=0.003). Patient medication adherence evaluated by the Morisky score was significantly improved (p=0.0036). CONCLUSION: Patient education improves knowledge and adherence to treatment among the older subjects and could improve the safety of prescription and reduce iatrogenic risk in geriatrics.

AB - Based on an in-depth case study, the authors of this paper highlight the difficulties faced by caregivers in the psychogeriatric care for elderly migrants. They show how both the history of emigration and the migratory experience can make this management complex. They articulate their reflection on the difficulties of diagnosis and therapeutic relationship, on the linguistic barrier around the question of old age in migration context. For the effective management of the elderly migrant, the authors suggest a strengthening of intercultural skills for caregivers. PMID- 29187332 TI - Designing gardens for people with dementia: literature review and evidence-based design conceptual frame. AB - More and more dwelling facilities for people with dementia invest gardens as convivial, resourceful, and relational places. However, there is a demand for scientific evidence of such statements. The aims of this literature review are to enlighten scientific evidence concerning uses and therapeutic virtues of garden for people with dementia, and to contribute to an evidence-based design approach by identifying key dimension of garden design. Twenty two articles were selected for this literature review and six clusters were identified. These clusters are discussed in a conceptual frame and discussed in an environment-behaviour approach. PMID- 29187333 TI - Toward a clinic of temporality? AB - The discovery of time cells has expanded our knowledge in the field of spatial and temporal information coding and the key role of the hippocampus. The internal clock model complemented with the attentional gate model allows a more in-depth understanding of the perception of time. The motor representation of duration is ensured by the basal ganglia, while the cerebellum synchronizes short duration for the movement. The right prefrontal cortex seemingly intervenes in the handling of temporal information in working memory. The temporal lobe ensures the comparison of durations, especially the right lobe for the reference durations and the medial lobe for the reproduction of durations in episodic memory. During normal aging, the hypothesis of slowing of the temporal processor is evoked when noting the perception of the acceleration of the passage of time that seemingly occurs with advancing age. The various studies pertaining specifically to time cognition, albeit heterogeneous in terms of methodology, attest to the wide ranging disturbances of this cognitive field during the course of numerous disorders, whether psychiatric - depression and schizophrenia notably - or neurological. Hence, perturbations in temporality are observed in focal brain lesions and in subcortical disorders, such as Parkinson's disease or Huntington's chorea. Alzheimer's disease represents a particularly fertile field of exploration with regard to time cognition and temporality. The objectified deconstruction of temporal experience provides insights into the very processes of temporality and their nature: episodic, semantic and procedural. In addition to exploration based on elementary stimuli, one should also consider the time lived, i.e. that of the subject, to better understand cognition as it relates to time. While the temporal dimension permeates the whole cognitive field, it remains largely neglected: integration of a genuine time cognition and temporality clinic in daily practice remains to be implemented. PMID- 29187334 TI - Cognitive profile in prodromal disease (dementia) with Lewy bodies. AB - This paper reviews findings on cognition in prodromal dementia with Lewy bodies (DLB). The issue of differential diagnosis between DLB and Alzheimer's disease (AD) on the one hand, and Parkinson's disease (PD) on the other hand, at prodromal stages of the diseases is discussed. The cognitive profile of prodromal DLB is also evaluated in terms of cognitive deficits and " cognitive weaknesses " (low performances although in normal range). Findings suggest that visuo constructive tests and verbal fluency are particularly relevant to dfferentiate DLB from AD. A similar finding is evident when comparing prodromal DLB and PD. Attentional, executive and visuo-constructive tests appear to be the best predictor of DLB. Moreover, investigation of the cognitive profile in prodromal DLB highlights that cognitive difficulties are diffuse. Yet it appears that difficulties in cortical visual abilities and executive functions are prominent and likely to account, at least partially, for cognitive disturbances observed in neuropsychological tests assessing other cognitive functions. PMID- 29187335 TI - Autobiographical memory compromise in Alzheimer's disease: a cognitive and clinical overview. AB - Autobiographical memory refers to memory for personal information. The compromise of autobiographical memory in Alzheimer's disease (AD) results in a loss of knowledge about events and facts that defined the patients' life, and consequently, degradation of their self-knowledge and sense of identity. The compromise of autobiographical memory in AD can be attributed to a diminished subjective experience of memory and a diminished sense of the self. Our review provides a comprehensive overview of cognitive and clinical processes that may be involved in difficulties to retrieve autobiographical memories in Alzheimer's disease. Our review also proposes a theoretical model according to which, the diminished ability to retrieve contextual information and the overgenerality of recall result in a diminished subjective experience of past and future thinking. Besides its theoretical contribution, our review proposes clinical applicability for evaluation and rehabilitation of autobiographical memory in AD. PMID- 29187337 TI - PRR signaling during in vitro macrophage differentiation from progenitors modulates their subsequent response to inflammatory stimuli. AB - Toll-like receptor (TLR) agonists drive hematopoietic stem and progenitor cells (HSPCs) to differentiate along the myeloid lineage in vitro and also in vivo following infection. In this study, we used an in vitro model of HSPC differentiation to investigate the functional consequences (cytokine production) that exposing HSPCs to various pathogen-associated molecular patterns (PAMPs) and Candida albicans cells have on the subsequently derived macrophages. Mouse HSPCs (Lin- cells) were cultured with GM-CSF to induce macrophage differentiation in the presence or absence of the following pattern recognition receptor (PRR) agonists: Pam3CSK4 (TLR2 ligand), LPS (TLR4 ligand), depleted zymosan (which only activates Dectin-1), or inactivated C. albicans yeasts (which activate several PRRs, mainly TLR2 and Dectin-1). Our data show that only pure TLR2 ligand exposure (transient and continuous) impacts the inflammatory function of GM-CSF derived macrophages, because Pam3CSK4-exposed HSPCs generate macrophages with a diminished ability to produce inflammatory cytokines. Interestingly, the Pam3CSK4 induced tolerance of macrophages (by transient exposure of HSPCs) is reinforced by subsequent exposure to C. albicans cells in GM-CSF-derived macrophages; however, the induced tolerance is partially reversed in M-CSF-derived macrophages. Therefore, the ability of macrophages to produce inflammatory cytokines is extremely dependent on how the HSPCs from which they are derived receive and integrate multiple microenvironmental signals (PRR ligands and/or CSFs). PMID- 29187338 TI - Effects of interleukin 17A (IL-17A) neutralization on murine hepatitis virus (MHV A59) infection. AB - Mice infected with mouse hepatitis virus A59 (MHV-A59) develop hepatitis and autoantibodies (autoAb) to liver and kidney fumarylacetoacetate hydrolase (FAH), a fact closely related to the release of alarmins such as uric acid and/or high mobility group box protein 1 (HMGB1). We studied the effect of neutralizing monoclonal antibodies (MAb) against IL-17A in our model of mouse MHV-A59 infection. MAb anti-IL-17F and anti-IFNgamma were used to complement the study. Results showed that transaminase levels markedly decreased in MHV-A59-infected mice treated with MAb anti-IL-17A whereas plasmatic Ig concentration sharply increased. Conversely, MAb anti-IL-17F enhanced transaminase liberation and did not affect Ig levels. Serum IFNgamma was detected in mice infected with MHV-A59 and its concentration increased after MAb anti-IL-17A administration. Besides, MAb anti-IFNgamma greatly augmented transaminase plasmatic levels. IL-17A neutralization did not affect MHV-A59-induction of HMGB1 liberation and slightly augmented plasmatic uric acid concentration. However, mice treated with the MAb failed to produce autoAb to FAH. The above results suggest a reciprocal regulation of Th1 and Th17 cells acting on the different MHV-A59 effects. In addition, it is proposed that IL-17A is involved in alarmins adjuvant effects leading to autoAb expression. PMID- 29187339 TI - Sophocarpine suppress inflammatory response in human fibroblast-like synoviocytes and in mice with collagen-induced arthritis. AB - Rheumatoid arthritis (RA) is a chronic autoimmune disease affecting nearly 1% of adults worldwide. This study aimed to investigate whether sophocarpine is a potential drug for treating RA. The cytotoxicity of sophocarpine to RA-fibroblast like synoviocytes (FLSs) was evaluated using 3-[4,-dimethylthiazol-2-y]-2,5 diphenyl-tetrazolium bromide (MTT) assays kit and released lactate dehydrogenase (LDH) assays. The transcription of proinflammatory cytokines in RA-FLSs was analyzed by reverse transcription and real-time polymerase chain reaction (RT PCR). The proteins levels were further verified by enzyme-linked immunosorbent assay (ELISA). The alterations in the mediators of mitogen-activated protein kinase (MAPK) and nuclear factor kappaB (NF-kappaB) signaling pathways were tested by western blotting. The clinical effects of sophocarpine were evaluated in type II collagen-induced arthritis (CIA) in DBA-/1 mouse model by scoring their clinical responses, synovitis, and cartilage destructions, and ELISA was employed to analyze the concentrations of proinflammatory cytokines in the serum of CIA mice. The results showed that sophocarpine contained low cytotoxicity to RA-FLS cells, and it was capable to downregulate the expressions of LPS-induced proinflammatory cytokines. The suppressions of MAPK and NF-kappaB signaling pathways by sophocarpine were also found in LPS-induced RA-FLSs. The attenuation of the symptoms in CIA mouse model were significant, in which concentrations of proinflammatory cytokines were decreased after the sophocarpine treatment. In this study, we demonstrated the potential of sophocarpine in treating RA, both in vitro and in vivo. Sophocarpine may be a potential drug in treating human RA. PMID- 29187340 TI - Enzyme-Linked Immunosorbent Spot (ELISpot) monitoring of cytokine-producing cells for the prediction of acute rejection in renal transplant patients. AB - The purpose of this study was to evaluate T-cell immunity markers using serial post-transplantation monitoring of cytokine-producing cells during the first post transplant months for the prediction of acute rejection and potentially chronic rejection of kidney allograft. We followed 57 kidney allograft recipients for meanly 3 years post-transplantation. Blood samples were collected pre-transplant, 2, 4 and 12 weeks post-transplant. The frequencies of IL-10-, IL-17- and IFN gamma-producing cells were determined in all time-points using ELISPOT assay. The results of ELISpot monitoring and levels of IL-23 and TGF-beta were compared between recipients with acute (n = 12) or chronic rejection episodes and patients with stable graft function (n = 45). In all post-transplant time-points, significantly high frequencies of IFN-gamma- and IL-17-producing cells and low frequency of IL-10-producing cells were observed in rejection group versus patients with stable graft function (P < 0.0001). The ROC curve analysis for determining the reliability of cytokine-producing cells for the prediction of acute rejection revealed that AUC was 0.046 for IL-10 (P < 0.001), 0.927 for IL 17 (P < 0.001) and 0.929 for INF-gamma-producing cells (P < 0.001). Our results indicate that analyzing the frequencies of INF-gamma/IL-10/IL-17-producing cells may define a reliable panel for the prediction of acute rejection within the first post-transplant year which could also be applicable for the prediction of chronic rejection episodes.

AB - A 14-year-old boy presented with several months of increasing abdominal girth and fatigue. Imaging confirmed massive ascites and hepatic congestion secondary to central hepatic venous obstruction. Several large intrahepatic collateral veins were seen draining via caudate and emissary veins. After an unsuccessful attempt at retrograde recanalization utilizing intravascular ultrasound, the right hepatic vein was recanalized in an antegrade fashion by way of a prominent caudate collateral vein, and subsequently stented. We herein discuss the established treatment options for Budd-Chiari syndrome and describe our experience employing a single-access liver floss technique. PMID- 29187342 TI - Assessing the Efficacy of Mobile Health Apps Using the Basic Principles of Cognitive Behavioral Therapy: Systematic Review. AB - BACKGROUND: Cognitive behavioral therapy (CBT) in its basic principle has developed itself as a stand-alone, substantial method of therapy. With effective application in therapy for a range of mental health issues, the spread of CBT methods to Web-based therapy sources is evident. The development of mobile phone apps using CBT principles is increasing within the research area. Despite the move to Web-based methods of therapy, it is argued that these methods lack the same efficacy of face-to-face therapy sessions. OBJECTIVE: The aim of this review was to assess extent research findings with regard to the effectiveness of CBT related mobile health (mHealth) apps. By assessing only studies employing a randomized controlled trial design, the review aimed to determine app efficacy within the highly regarded method of investigation. METHODS: A comprehensive literature search was conducted across several databases. Search results were filtered, and results were subject to strict inclusion and exclusion criteria because of the nature of the review. Where possible, analysis of effect size was calculated and results reported. RESULTS: A total of 8 studies investigating the effectiveness of mHealth CBT-related apps across a range of mental health issues were reviewed. Three studies used the app against a control group, and 5 studies used the app intervention against another form of treatment or intervention. A range of effect sizes were seen across all included studies (d=-0.13 to 1.83; 0.03-1.44), with the largest effects often being seen when comparing the data from pre- to posttest for the app engaged group. CONCLUSIONS: The studies reviewed support the use of mHealth apps containing CBT principles for a range of mental health issues. However, the effectiveness over longer time periods should be assessed. Researchers and professionals should seek to collaborate effectively when creating new apps to enhance their effectiveness as a treatment for the general public. PMID- 29187343 TI - An eHealth Application of Self-Reported Sports-Related Injuries and Illnesses in Paralympic Sport: Pilot Feasibility and Usability Study. AB - BACKGROUND: Sport participation is associated with a risk of sports-related injuries and illnesses, and Paralympic athletes' additional medical issues can be a challenge to health care providers and medical staff. However, few prospective studies have assessed sports-related injuries and illnesses in Paralympic sport (SRIIPS) over time. Advances in mobile phone technology and networking systems offer novel opportunities to develop innovative eHealth applications for collection of athletes' self-reports. Using eHealth applications for collection of self-reported SRIIPS is an unexplored area, and before initiation of full scale research of SRIIPS, the feasibility and usability of such an approach needs to be ascertained. OBJECTIVE: The aim of this study was to perform a 4-week pilot study and (1) evaluate the monitoring feasibility and system usability of a novel eHealth application for self-reported SRIIPS and (2) report preliminary data on SRIIPS. METHODS: An eHealth application for routine collection of data from athletes was developed and adapted to Paralympic athletes. A 4-week pilot study was performed where Paralympic athletes (n=28) were asked to weekly self-report sport exposure, training load, general well-being, pain, sleep, anxiety, and possible SRIIPS. The data collection was followed by a poststudy use assessment survey. Quantitative data related to the system use (eg, completed self-reports, missing responses, and errors) were analyzed using descriptive statistics. The qualitative feasibility and usability data provided by the athletes were condensed and categorized using thematic analysis methods. RESULTS: The weekly response rate was 95%. The athletes were of the opinion that the eHealth application was usable and feasible but stated that it was not fully adapted to Paralympic athletes and their impairments. For example, it was difficult to understand how a new injury or illness should be identified when the impairment was involved. More survey items related to the impairments were requested, as the athletes perceived that injuries and illnesses often occurred because of the impairment. Options for description of multifactorial incidents including an injury, an illness, and the impairment were also insufficient. Few technical issues were encountered, but athletes with visual impairment reported usability difficulties with the speech synthesizer. An incidence rate of 1.8 injuries and 1.7 illnesses per 100 hours of athlete exposure were recorded. The weekly pain prevalence was 56% and the impairment contributed to 20% of the reported incidents. CONCLUSIONS: The novel eHealth-based application for self-reported SRIIPS developed and tested in this pilot study was generally feasible and usable. With some adaptation to accommodate Paralympic athletes' prerequisites and improved technical support for athletes with visual impairment, this application can be recommended for use in prospective studies of SRIIPS.

PMID- 29187344 TI - One Drop | Mobile on iPhone and Apple Watch: An Evaluation of HbA1c Improvement Associated With Tracking Self-Care. AB - BACKGROUND: The One Drop | Mobile app supports manual and passive (via HealthKit and One Drop's glucose meter) tracking of self-care and glycated hemoglobin A1c (HbA1c). OBJECTIVE: We assessed the HbA1c change of a sample of people with type 1 diabetes (T1D) or type 2 diabetes (T2D) using the One Drop | Mobile app on iPhone and Apple Watch, and tested relationships between self-care tracking with the app and HbA1c change. METHODS: In June 2017, we identified people with diabetes using the One Drop | Mobile app on iPhone and Apple Watch who entered two HbA1c measurements in the app 60 to 365 days apart. We assessed the relationship between using the app and HbA1c change. RESULTS: Users had T1D (n=65) or T2D (n=191), were 22.7% (58/219) female, with diabetes for a mean 8.34 (SD 8.79) years, and tracked a mean 2176.35 (SD 3430.23) self-care activities between HbA1c entries. There was a significant 1.36% or 14.9 mmol/mol HbA1c reduction (F=62.60, P<.001) from the first (8.72%, 71.8 mmol/mol) to second HbA1c (7.36%, 56.9 mmol/mol) measurement. Tracking carbohydrates was independently associated with greater HbA1c improvement (all P<.01). CONCLUSIONS: Using One Drop | Mobile on iPhone and Apple Watch may favorably impact glycemic control. PMID- 29187345 TI - Wide-field en face swept-source optical coherence tomography angiography using extended field imaging in diabetic retinopathy. AB - AIMS: To examine the feasibility of wide-field en face swept-source optical coherence tomography angiography (SS-OCTA) with extended field imaging (EFI) for evaluation of the retinal vasculature in diabetic retinopathy (DR). METHODS: This study included 37 eyes of 27 patients (age, 65+/-10 years; male patients, 18; female patients, 9) with DR. All patients underwent comprehensive ophthalmological examination, including OCTA and fluorescein angiography (FA). The imaging methods were compared for visible field of view, presence and extent of non-perfused areas (NPAs), presence and number of new blood vessels (NVs), vessel density (VD) and patient comfort level measured by Visual Analogue Scale. RESULTS: SS-OCTA with EFI allowed capture of larger areas (by 1.80+/-0.18 times on average) of the fundus than SS-OCTA without EFI. Compared with FA, the sensitivities of SS-OCTA with EFI for detection of NPAs and NVs were 96% and 79%, respectively, with specificities of 100% and 96%, respectively. There was no significant difference in extent of NPAs (61.2+/-45.8 vs 61.5+/-55.0 disc areas, P=0.99) or number of NVs (1.5+/-3.3 vs 0.9+/-1.8, P=0.68) between FA and SS-OCTA with EFI. VD showed significantly lower values in EFI SS-OCTA than in those acquired without EFI (31.6%+/-4.3% vs 34.2%+/-4.3%, P<0.001). Wide-field OCTA with EFI was significantly more comfortable for patients than FA (P<0.001). CONCLUSIONS: SS-OCTA with EFI allows acquisition of wide-field en face images of the retinal vasculature in patients with DR, with greater patient comfort than FA. PMID- 29187346 TI - Influence of early childhood burns on school performance: an Australian population study. AB - OBJECTIVES: To determine the influence of burn injuries on childhood performance in national standardised curriculum-based school tests. DESIGN: Birth and health records of 977 children who were hospitalised with a burn injury between 2000 and 2006 in the state of New South Wales, Australia, were linked to performance scores in the National Assessment Program: Literacy and Numeracy test, a compulsory nationwide curriculum-based test (CBT) and compared with children who were not hospitalised for burns and who were matched for birth year, gender, gestation and socioeconomic status. MAIN OUTCOME MEASURES: Test scores in years 3 (ages 8-9), 5 (ages 10-11) and 7 (ages 13-14) in numeracy, writing, reading, spelling, grammar and punctuation. RESULTS: Mean age at first burn injury was 28 months (median: 20, range: 0-140). Children with burns were significantly more likely to have younger mothers (28.5 vs 29.6 years) (P<0.001), be indigenous (OR 2.5 (95% CI 2.1 to 3.1)) (P<0.001) and have siblings (OR 1.2 (95% CI 1.1 to 1.4)) (P<0.001). They were also less likely to meet national minimum standards in most domains of testing until year 5, even after adjustment for parental education levels, parental smoking, maternal age and indigenous status. Each 10% increase in total body surface area burnt was associated with a decrease in year 5 scores by 37.0% in numeracy and 71.9% in writing. CONCLUSIONS: Most childhood burn injuries occur before the start of formal schooling. Children who are hospitalised for burns perform more poorly in CBT even after accounting for family and socioeconomic disadvantage. Rehabilitation of children with burn injuries must address school performance to decrease any long-term negative societal impact of burns.

PMID- 29187349 TI - Isokinetic strength assessment offers limited predictive validity for detecting risk of future hamstring strain in sport: a systematic review and meta-analysis. AB - OBJECTIVE: To examine the value of isokinetic strength assessment for predicting risk of hamstring strain injury, and to direct future research into hamstring strain injuries. DESIGN: Systematic review. DATA SOURCES: Database searches for Medline, CINAHL, Embase, AMED, AUSPORT, SPORTDiscus, PEDro and Cochrane Library from inception to April 2017. Manual reference checks, ahead-of-press and citation tracking. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Prospective studies evaluating isokinetic hamstrings, quadriceps and hip extensor strength testing as a risk factor for occurrence of hamstring muscle strain. METHODS: Independent search result screening. Risk of bias assessment by independent reviewers using Quality in Prognosis Studies tool. Best evidence synthesis and meta-analyses of standardised mean difference (SMD). RESULTS: Twelve studies were included, capturing 508 hamstring strain injuries in 2912 athletes. Isokinetic knee flexor, knee extensor and hip extensor outputs were examined at angular velocities ranging 30-300 degrees /s, concentric or eccentric, and relative (Nm/kg) or absolute (Nm) measures. Strength ratios ranged between 30 degrees /s and 300 degrees /s. Meta-analyses revealed a small, significant predictive effect for absolute (SMD=-0.16, P=0.04, 95% CI -0.31 to -0.01) and relative (SMD=-0.17, P=0.03, 95% CI -0.33 to -0.014) eccentric knee flexor strength (60 degrees /s). No other testing speed or strength ratio showed statistical association. Best evidence synthesis found over half of all variables had moderate or strong evidence for no association with future hamstring injury. SUMMARY/CONCLUSION: Despite an isolated finding for eccentric knee flexor strength at slow speeds, the role and application of isokinetic assessment for predicting hamstring strain risk should be reconsidered, particularly given costs and specialised training required.

PMID- 29187350 TI - Risk of losing remission, low disease activity or radiographic progression in case of bDMARD discontinuation or tapering in rheumatoid arthritis: systematic analysis of the literature and meta-analysis. AB - OBJECTIVES: To assess the risk of losing remission, low disease activity (LDA) or radiographic progression in the case of (1) discontinuing or (2) tapering doses of biological disease-modifying antirheumatic drugs (bDMARDs) compared with continuation of the initial treatment regimen in rheumatoid arthritis (RA) patients with remission or LDA. MATERIALS AND METHODS: A systematic literature analysis was carried out through May 2017 on the PubMed, Embase, Cochrane and international congress databases, selecting controlled trials comparing bDMARDs discontinuation/tapering versus continuation in RA patients with remission or LDA. The meta-analysis assessed the risk ratio (RR) and 95% CI of losing remission or LDA and the risk of radiographic progression after (1) discontinuing and (2) tapering doses of bDMARDs versus continuing the initial treatment. RESULTS: The meta-analysis comparing bDMARDs discontinuation versus continuation performed on nine trials showed an increased risk of losing remission (RR (95% CI)=1.97(1.43 to 2.73), P<0.0001) or LDA (RR (95% CI)=2.24(1.52 to 3.30), P<0.0001) and an increased risk of radiographic progression (RR (95% CI)=1.09(1.02 to 1.17), P=0.01) in case of bDMARD discontinuation. The meta analysis comparing bDMARDs tapering versus continuation performed on 11 trials showed an increased risk of losing remission (RR (95% CI)=1.23(1.06 to 1.42), P=0.006) but no increased risk of losing LDA (RR (95% CI)=1.02 (0.85 to 1.23), P=0.81) nor any increased risk of radiographic progression (RR (95% CI)=1.09(0.94 to 1.26), P=0.26) in case of bDMARD tapering. CONCLUSION: Discontinuation of bDMARDs leads to an increased risk of losing remission or LDA and radiographic progression, while tapering doses of bDMARDs does not increase the risk of relapse (LDA) or radiographic progression, even though there is an increased risk of losing remission.

AB - BACKGROUND: Advancements in the quality and availability of highly sensitive analytical instrumentation and methodologies have led to increased interest in the use of microsamples. Among microsamples, dried blood spots (DBS) are the most well-known. Although there have been a variety of review papers published on DBS, there has been no attempt at describing the full range of analytes measurable in DBS, or any systematic approach published for characterizing the strengths and weaknesses associated with adoption of DBS analyses. CONTENT: A scoping review of reviews methodology was used for characterizing the state of the science in DBS. We identified 2018 analytes measured in DBS and found every common analytic method applied to traditional liquid samples had been applied to DBS samples. Analytes covered a broad range of biomarkers that included genes, transcripts, proteins, and metabolites. Strengths of DBS enable its application in most clinical and laboratory settings, and the removal of phlebotomy and the need for refrigeration have expanded biosampling to hard-to-reach and vulnerable populations. Weaknesses may limit adoption in the near term because DBS is a nontraditional sample often requiring conversion of measurements to plasma or serum values. Opportunities presented by novel methodologies may obviate many of the current limitations, but threats around the ethical use of residual samples must be considered by potential adopters. SUMMARY: DBS provide a wide range of potential applications that extend beyond the reach of traditional samples. Current limitations are serious but not intractable. Technological advancements will likely continue to minimize constraints around DBS adoption.

AB - BACKGROUND: Associations between dairy intake and body mass index (BMI) have been inconsistently observed in epidemiological studies, and the causal relationship remains ill defined. METHODS: We performed Mendelian randomization (MR) analysis using an established dairy intake-associated genetic polymorphism located upstream of the lactase gene (LCT-13910 C/T, rs4988235) as an instrumental variable (IV). Linear regression models were fitted to analyze associations between (a) dairy intake and BMI, (b) rs4988235 and dairy intake, and (c) rs4988235 and BMI in each study. The causal effect of dairy intake on BMI was quantified by IV estimators among 184802 participants from 25 studies. RESULTS: Higher dairy intake was associated with higher BMI (beta = 0.03 kg/m2 per serving/day; 95% CI, 0.00-0.06; P = 0.04), whereas the LCT genotype with 1 or 2 T allele was significantly associated with 0.20 (95% CI, 0.14-0.25) serving/day higher dairy intake (P = 3.15 * 10-12) and 0.12 (95% CI, 0.06-0.17) kg/m2 higher BMI (P = 2.11 * 10-5). MR analysis showed that the genetically determined higher dairy intake was significantly associated with higher BMI (beta = 0.60 kg/m2 per serving/day; 95% CI, 0.27-0.92; P = 3.0 * 10-4). CONCLUSIONS: The present study provides strong evidence to support a causal effect of higher dairy intake on increased BMI among adults.

AB - Objectives To estimate the effects of vitamin D supplementation during pregnancy on 11 maternal and 27 neonatal/infant outcomes; to determine frequencies at which trial outcome data were missing, unreported, or inconsistently reported; and to project the potential contributions of registered ongoing or planned trials.Design Systematic review and meta-analysis of randomised controlled trials; systematic review of registered but unpublished trials.Data sources Medline, Embase, PubMed, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials from inception to September 2017; manual searches of reference lists of systematic reviews identified in the electronic search; and online trial registries for unpublished, ongoing, or planned trials.Eligibility criteria for study selection Trials of prenatal vitamin D supplementation with randomised allocation and control groups administered placebo, no vitamin D, or vitamin D <=600 IU/day (or its equivalent), and published in a peer reviewed journal.Results 43 trials (8406 participants) were eligible for meta-analyses. Median sample size was 133 participants. Vitamin D increased maternal/cord serum concentration of 25-hydroxyvitamin D, but the dose response effect was weak. Maternal clinical outcomes were rarely ascertained or reported, but available data did not provide evidence of benefits. Overall, vitamin D increased mean birth weight of 58.33 g (95% confidence interval 18.88 g to 97.78 g; 37 comparisons) and reduced the risk of small for gestational age births (risk ratio 0.60, 95% confidence interval 0.40 to 0.90; seven comparisons), but findings were not robust in sensitivity and subgroup analyses. There was no effect on preterm birth (1.0, 0.77 to 1.30; 15 comparisons). There was strong evidence that prenatal vitamin D reduced the risk of offspring wheeze by age 3 years (0.81, 0.67 to 0.98; two comparisons). For most outcomes, meta analyses included data from a minority of trials. Only eight of 43 trials (19%) had an overall low risk of bias. Thirty five planned/ongoing randomised controlled trials could contribute 12 530 additional participants to future reviews.Conclusions Most trials on prenatal vitamin D published by September 2017 were small and of low quality. The evidence to date seems insufficient to guide clinical or policy recommendations. Future trials should be designed and powered to examine clinical endpoints, including maternal conditions related to pregnancy (such as pre-eclampsia), infant growth, and respiratory outcomes.Systematic review registration PROSPERO CRD42016051292.

AB - Inhibitor of apoptosis protein (IAP) antagonists are in clinical trials for a variety of cancers, and mouse models show synergism between IAP antagonists and anti-PD-1 immunotherapy. Although IAP antagonists affect the intrinsic signaling of tumor cells, their most pronounced effects are on immune cells and the generation of antitumor immunity. Here, we examined the effects of IAP antagonism on T-cell development using mouse fetal thymic organ culture and observed a selective loss of iNKT cells, an effector cell type of potential importance for cancer immunotherapy. Thymic iNKT-cell development probably failed due to increased strength of TCR signal leading to negative selection, given that mature iNKT cells treated with IAP antagonists were not depleted, but had enhanced cytokine production in both mouse and human ex vivo cultures. Consistent with this, mature mouse primary iNKT cells and iNKT hybridomas increased production of effector cytokines in the presence of IAP antagonists. In vivo administration of IAP antagonists and alpha-GalCer resulted in increased IFNgamma and IL-2 production from iNKT cells and decreased tumor burden in a mouse model of melanoma lung metastasis. Human iNKT cells also proliferated and increased IFNgamma production dramatically in the presence of IAP antagonists, demonstrating the utility of these compounds in adoptive therapy of iNKT cells.

AB - Emerging evidence implicates environmental endocrine-disrupting chemicals (EDCs) in the pathogenesis of metabolic diseases such as obesity and diabetes; however, the interactions between EDCs and traditional risk factors in disease pathogenesis remain incompletely characterized. The present study interrogates the interaction of the EDC tolylfluanid (TF) and traditional dietary stressors in the promotion of metabolic dysfunction. Eight-week-old male C57BL/6 mice were fed a high-fat, high-sucrose diet (HFHSD) or a high-sucrose diet (HSD), with or without TF supplementation at 100 MUg/g, for 12 weeks. Food intake, body weight and visceral adiposity were quantified. Glucose homeostasis was interrogated by intraperitoneal glucose and insulin tolerance tests at 9 and 10 weeks of exposure, respectively. After 12 weeks of dietary exposure, metabolic cage analyses were performed to interrogate nutrient handling and energy expenditure. In the background of an HFHSD, TF promoted glucose intolerance; however, weight gain and insulin sensitivity were unchanged, and visceral adiposity was reduced. In the background of an HSD, TF increased visceral adiposity; however, glucose tolerance and insulin sensitivity were unchanged, while weight gain was reduced. Thus, these analyses reveal that the metabolic perturbations induced by dietary exposure to TF, including the directionality of alterations in body weight gain, visceral adiposity and glucose homeostasis, are influenced by dietary macronutrient composition, suggesting that populations may exhibit distinct metabolic risks based on their unique dietary characteristics. PMID- 29187363 TI - TRPV4 heats up ANO1-dependent exocrine gland fluid secretion. AB - Several ion channels and transporters regulate fluid secretion in salivary and lacrimal glands. In salivary glands, the major anion channel involved in fluid secretion is the calcium-activated chloride channel anoctamin 1 (ANO1). Several members of the transient receptor potential (TRP) channel superfamily regulate ANO1 activity. Here, we report a functional interaction between thermosensitive TRP vanilloid (TRPV)4 and ANO1 in acinar cells isolated from mouse salivary and lacrimal glands. TRPV4 activation induced chloride currents and shrinkage of acinar cells by increasing intracellular calcium concentrations. The chloride currents evoked by a TRPV4-specific activator (GSK1016790A) were identified as ANO1-mediated currents. Moreover, TRPV4 activation by an inositol 1,4,5 trisphosphate (IP3)-dependent mechanism was found to contribute to the muscarinic pathway of fluid secretion. Muscarinic stimulation of saliva and tear secretion was down-regulated in both TRPV4-deficient mice and in acinar cells treated with a TRPV4-specific antagonist (HC-067047). Furthermore, the temperature dependence of muscarinic salivation was shown to depend mainly on TRPV4. Our results suggest that TRPV4 interacts with IP3 receptors and ANO1 to regulate the muscarinic pathway that mediates salivation and lacrimation.-Derouiche, S., Takayama, Y., Murakami, M., Tominaga, M. TRPV4 heats up ANO1-dependent exocrine gland fluid secretion. PMID- 29187362 TI - IKK2/NF-kappaB signaling protects neurons after traumatic brain injury. AB - Traumatic brain injury (TBI) is the leading cause of death in young adults. After the initial injury, a poorly understood secondary phase, including a strong inflammatory response determines the final outcome of TBI. The inhibitor of NF kappaB kinase (IKK)/NF-kappaB signaling system is the key regulator of inflammation and also critically involved in regulation of neuronal survival and synaptic plasticity. We addressed the neuron-specific function of IKK2/NF-kappaB signaling pathway in TBI using an experimental model of closed-head injury (CHI) in combination with mouse models allowing conditional regulation of IKK/NF-kappaB signaling in excitatory forebrain neurons. We found that repression of IKK2/NF kappaB signaling in neurons increases the acute posttraumatic mortality rate, worsens the neurological outcome, and promotes neuronal cell death by apoptosis, thus resulting in enhanced proinflammatory gene expression. As a potential mechanism, we identified elevated levels of the proapoptotic mediators Bax and Bad and enhanced expression of stress response genes. This phenotype is also observed when neuronal IKK/NF-kappaB activity is inhibited just before CHI. In contrast, neuron-specific activation of IKK/NF-kappaB signaling does not alter the TBI outcome. Thus, this study demonstrates that physiological neuronal IKK/NF kappaB signaling is necessary and sufficient to protect neurons from trauma consequences.-Mettang, M., Reichel, S. N., Lattke, M., Palmer, A., Abaei, A., Rasche, V., Huber-Lang, M., Baumann, B., Wirth, T. IKK2/NF-kappaB signaling protects neurons after traumatic brain injury. PMID- 29187364 TI - Characterization of CD38 in the major cell types of the heart: endothelial cells highly express CD38 with activation by hypoxia-reoxygenation triggering NAD(P)H depletion. AB - The NAD(P)+-hydrolyzing enzyme CD38 is activated in the heart during the process of ischemia and reperfusion, triggering NAD(P)(H) depletion. However, the presence and role of CD38 in the major cell types of the heart are unknown. Therefore, we characterize the presence and function of CD38 in cardiac myocytes, endothelial cells, and fibroblasts. To comprehensively evaluate CD38 in these cells, we measured gene transcription via mRNA, as well as protein expression and enzymatic activity. Endothelial cells strongly expressed CD38, while only low expression was present in cardiac myocytes with intermediate levels in fibroblasts. In view of this high level expression in endothelial cells and the proposed role of CD38 in the pathogenesis of endothelial dysfunction, endothelial cells were subjected to hypoxia-reoxygenation to characterize the effect of this stress on CD38 expression and activity. An activity-based CD38 imaging method and CD38 activity assays were used to characterize CD38 activity in normoxic and hypoxic-reoxygenated endothelial cells, with marked CD38 activation seen following hypoxia-reoxygenation. To test the impact of hypoxia-reoxygenation induced CD38 activation on endothelial cells, NAD(P)(H) levels and endothelial nitric oxide synthase (eNOS)-derived NO production were measured. Marked NADP(H) depletion with loss of NO and increase in superoxide production occurred following hypoxia-reoxygenation that was prevented by CD38 inhibition or knockdown. Thus, endothelial cells have high expression of CD38 which is activated by hypoxia-reoxygenation triggering CD38-mediated NADP(H) depletion with loss of eNOS-mediated NO generation and increased eNOS uncoupling. This demonstrates the importance of CD38 in the endothelium and explains the basis by which CD38 triggers post-ischemic endothelial dysfunction. PMID- 29187365 TI - Foxo1 nucleo-cytoplasmic distribution and unidirectional nuclear influx are the same in nuclei in a single skeletal muscle fiber but vary between fibers. AB - Foxo transcription factors promote protein breakdown and atrophy of skeletal muscle fibers. Foxo transcriptional effectiveness is largely determined by phosphorylation-dependent nucleo-cytoplasmic shuttling. Imaging Foxo1-green fluorescent protein (GFP) over time in 124 nuclei in 68 multinucleated adult skeletal muscle fibers under control culture conditions reveals large variability between fibers in Foxo1-GFP nucleo-cytoplasmic concentration ratio (N/C) and in the apparent rate coefficient ( kI') for Foxo1-GFP unidirectional nuclear influx (measured with efflux blocked by leptomycin B). Pairs of values of N/C or of kI' from different nuclei in the same fiber were essentially the same, but only weakly correlated in nuclei from different fibers in the same culture well. Thus, fiber to fiber variability of cellular factors, but not extracellular factors, determines Foxo1 distribution. Over all nuclei, N/C and kI' were closely proportional, indicating that kI' is the major determinant of Foxo1 distribution. IGF-I activation of Foxo kinase Akt reduces variability by decreasing kI' and N/C in all fibers. However, inhibiting Akt did not drive kI' uniformly high, indicating other pathways in Foxo1 regulation. PMID- 29187366 TI - Cell confluence regulates claudin-2 expression: possible role for ZO-1 and Rac. AB - Claudin-2 (Cldn-2) is a channel-forming tight junction (TJ) protein in the proximal tubules that mediates paracellular Na+ transport and has also emerged as a regulator of proliferation and migration. Expression of Cldn-2 is altered by numerous stimuli, but the underlying mechanisms remain incompletely understood. Here we show that Cldn-2 protein and mRNA expression were low in subconfluent tubular cells and increased during junction maturation. Cldn-1 or occludin did not exhibit similar confluence-dependence. Conversely, disruption of TJs by Ca2+ removal or silencing of zonula occludens-1 (ZO-1) or ZO-2 induced a large drop in Cldn-2 abundance. Immunofluorescent staining revealed a more uneven Cldn-2 staining in nascent, Cldn-1-positive TJs. Subconfluence and ZO-1 silencing augmented Cldn-2 degradation and reduced Cldn-2 promoter activity, suggesting that insertion into the TJs slows Cldn-2 turnover. Indeed, blocking endocytosis or lysosomal degradation increased Cldn-2 abundance. Cell confluence increased expression of the junctional adapters ZO-1 and -2, and the small GTPase Rac, and elevated Rac activity and p21-activated kinase (Pak) phosphorylation, suggesting that they might mediate confluence-dependent Cldn-2 regulation. Indeed, Rac silencing or Pak inhibition strongly reduced Cldn-2 protein abundance, which was likely the combined effect on turnover, as these interventions reduced Cldn-2 promoter activity and augmented Cldn-2 degradation. Taken together, our data suggest that TJ integrity and maturity, ZO-1 expression/TJ localization, and Rac/Pak control Cldn-2 degradation and synthesis. A feedback mechanism connecting Cldn-2 expression with junction remodeling, e.g., during wound healing, epithelial-mesenchymal transition, or tumor metastasis formation, may have important downstream effects on permeability, proliferation, and migration. PMID- 29187367 TI - Oxidative stress increases megalin expression in the renal proximal tubules during the normoalbuminuric stage of diabetes mellitus. AB - Megalin, an endocytic receptor expressed in proximal tubule cells, plays a critical role in renal tubular protein reabsorption and is associated with the albuminuria observed in diabetic nephropathy. We have previously reported increased oxidant production in the renal cortex during the normoalbuminuric stage of diabetes mellitus (DM); however, the relationship between oxidative stress and renal megalin expression during the normoalbuminuric stage of DM remains unclear. In the present study, we evaluated whether oxidative stress affects megalin expression in the normoalbuminuric stage of DM in a streptozotocin-induced diabetic rat model and in immortalized human proximal tubular cells (HK-2). We demonstrated that increased expression of renal megalin accompanies oxidative stress during the early stage of DM, before albuminuria development. Telmisartan treatment prevented the diabetes-induced elevation in megalin level, possibly through an oxidative stress-dependent mechanism. In HK-2 cells, hydrogen peroxide significantly increased megalin levels in a dose- and time-dependent manner; however, the elevation in megalin expression was decreased following prolonged exposure to severe oxidative stress induced by 0.4 mmol/l hydrogen peroxide. High-glucose treatment also significantly increased megalin expression in HK-2 cells. Concurrent administration of the antioxidant N-acetyl cysteine blocked the effects of high glucose on megalin expression. Furthermore, the hydrogen peroxide-induced increase in megalin expression was blocked by treatment with phosphatidylinositol 3-kinase and Akt inhibitors. Increase of phosphorylated Akt expression was also seen in the renal cortex of diabetic rats. Taken together, our results indicate that mild oxidative stress increases renal megalin expression through the phosphatidylinositol 3-kinase-Akt pathway in the normoalbuminuric stage of DM. PMID- 29187370 TI - Ste20-like kinase, SLK, a novel mediator of podocyte integrity. AB - SLK is essential for embryonic development and may play a key role in wound healing, tumor growth, and metastasis. Expression and activation of SLK are increased in kidney development and during recovery from ischemic acute kidney injury. Overexpression of SLK in glomerular epithelial cells/podocytes in vivo induces injury and proteinuria. Conversely, reduced SLK expression leads to abnormalities in cell adhesion, spreading, and motility. Tight regulation of SLK expression thus may be critical for normal renal structure and function. We produced podocyte-specific SLK-knockout mice to address the functional role of SLK in podocytes. Mice with podocyte-specific deletion of SLK showed reduced glomerular SLK expression and activity compared with control. Podocyte-specific deletion of SLK resulted in albuminuria at 4-5 mo of age in male mice and 8-9 mo in female mice, which persisted for up to 13 mo. At 11-12 mo, knockout mice showed ultrastructural changes, including focal foot process effacement and microvillous transformation of podocyte plasma membranes. Mean foot process width was approximately twofold greater in knockout mice compared with control. Podocyte number was reduced by 35% in knockout mice compared with control, and expression of nephrin, synaptopodin, and podocalyxin was reduced in knockout mice by 20-30%. In summary, podocyte-specific deletion of SLK leads to albuminuria, loss of podocytes, and morphological evidence of podocyte injury. Thus, SLK is essential to the maintenance of podocyte integrity as mice age. PMID- 29187368 TI - N-linked glycans are required on epithelial Na+ channel subunits for maturation and surface expression. AB - Epithelial Na+ channel (ENaC) subunits undergo N-linked glycosylation in the endoplasmic reticulum where they assemble into an alphabetagamma complex. Six, 13, and 5 consensus sites (Asn-X-Ser/Thr) for N-glycosylation reside in the extracellular domains of the mouse alpha-, beta-, and gamma-subunits, respectively. Because the importance of ENaC N-linked glycans has not been fully addressed, we examined the effect of preventing N-glycosylation of specific subunits on channel function, expression, maturation, and folding. Heterologous expression in Xenopus oocytes or Fischer rat thyroid cells with alphabetagamma ENaC lacking N-linked glycans on a single subunit reduced ENaC activity as well as the inhibitory response to extracellular Na+. The lack of N-linked glycans on the beta-subunit also precluded channel activation by trypsin. However, channel activation by shear stress was N-linked glycan independent, regardless of which subunit was modified. We also discovered that the lack of N-linked glycans on any one subunit reduced the total and surface levels of cognate subunits. The lack of N-linked glycans on the beta-subunit had the largest effect on total levels, with the lack of N-linked glycans on the gamma- and alpha-subunits having intermediate and modest effects, respectively. Finally, channels with wild-type beta-subunits were more sensitive to limited trypsin proteolysis than channels lacking N-linked glycans on the beta-subunit. Our results indicate that N-linked glycans on each subunit are required for proper folding, maturation, surface expression, and function of the channel. PMID- 29187369 TI - Pharmacological and genetic inhibition of downstream targets of p38 MAPK in experimental nephrotic syndrome. AB - Nie X, Chanley MA, Pengal R, Thomas DB, Agrawal S, Smoyer WE. Pharmacological and genetic inhibition of downstream targets of p38 MAPK in experimental nephrotic syndrome. Am J Physiol Renal Physiol 314: F602-F613, 2018. First published November 29, 2017; doi: 10.1152/ajprenal.00207.2017 .-The p38 MAPK pathway plays a crucial role in various glomerulopathies, with activation being associated with disease and inhibition being associated with disease amelioration. We hypothesized that the downstream targets of p38 MAPK, MAPK-activated protein kinase 2 and/or 3 (MK2 and/or MK3), play an important role in mediating injury in experimental nephrotic syndrome via their actions on their downstream substrates heat shock protein B1 (HSPB1) and cyclooxygenase-2 (COX-2). To test this hypothesis, the effects of both pharmacological and genetic inhibition of MK2 and MK3 were examined in mouse adriamycin (ADR) and rat puromycin aminonucleoside (PAN) nephropathy models. MK2-/-, MK3-/-, and MK2-/-MK3-/- mice were generated in the Sv129 background and subjected to ADR-induced nephropathy. MK2 and MK3 protein expression was completely abrogated in the respective knockout genotypes, and massive proteinuria and renal histopathological changes developed after ADR treatment. Furthermore, renal cortical HSPB1 was induced in all four genotypes by day 21, but HSPB1 was activated only in the wild-type and MK3-/- mice. Expression of the stress proteins HSPB8 and glucose-regulated protein 78 (GRP78) remained unaltered across all genotypes. Finally, while MK2 and/or MK3-knockout downregulated the proinflammatory enzyme COX-2, ADR significantly induced renal cortical COX-2 only in MK2-/- mice. Additionally, pharmacological MK2 inhibition with PF-318 during PAN-induced nephropathy did not result in significant proteinuria reduction in rats. Together, these data suggest that while the inhibition of MK2 and/or MK3 regulates the renal stress response, our currently available approaches are not yet able to safely and effectively reduce proteinuria in experimental nephrotic syndrome and that other p38MAPK downstream targets should also be considered to improve the future treatment of glomerular disease. PMID- 29187371 TI - Effects of erythropoietin receptor activity on angiogenesis, tubular injury, and fibrosis in acute kidney injury: a "U-shaped" relationship. AB - The erythropoietin receptor (EpoR) is widely expressed but its renoprotective action is unexplored. To examine the role of EpoR in vivo in the kidney, we induced acute kidney injury (AKI) by ischemia-reperfusion in mice with different EpoR bioactivities in the kidney. EpoR bioactivity was reduced by knockin of wild type human EpoR, which is hypofunctional relative to murine EpoR, and a renal tubule-specific EpoR knockout. These mice had lower EPO/EpoR activity and lower autophagy flux in renal tubules. Upon AKI induction, they exhibited worse renal function and structural damage, more apoptosis at the acute stage (<7 days), and slower recovery with more tubulointerstitial fibrosis at the subacute stage (14 days). In contrast, mice with hyperactive EpoR signaling from knockin of a constitutively active human EpoR had higher autophagic flux, milder kidney damage, and better renal function at the acute stage but, surprisingly, worse tubulointerstitial fibrosis and renal function at the subacute stage. Either excess or deficient EpoR activity in the kidney was associated with abnormal peritubular capillaries and tubular hypoxia, creating a "U-shaped" relationship. The direct effects of EpoR on tubular cells were confirmed in vitro by a hydrogen peroxide model using primary cultured proximal tubule cells with different EpoR activities. In summary, normal erythropoietin (EPO)/EpoR signaling in renal tubules provides defense against renal tubular injury maintains the autophagy apoptosis balance and peritubular capillary integrity. High and low EPO/EpoR bioactivities both lead to vascular defect, and high EpoR activity overides the tubular protective effects in AKI recovery. PMID- 29187372 TI - Renal tubular ACE-mediated tubular injury is the major contributor to microalbuminuria in early diabetic nephropathy. AB - Diabetic nephropathy is a major cause of end-stage renal disease in developed countries. While angiotensin-converting enzyme (ACE) inhibitors are used to treat diabetic nephropathy, how intrarenal ACE contributes to diabetic renal injury is uncertain. Here, two mouse models with different patterns of renal ACE expression were studied to determine the specific contribution of tubular vs. glomerular ACE to early diabetic nephropathy: it-ACE mice, which make endothelial ACE but lack ACE expression by renal tubular epithelium, and ACE 3/9 mice, which lack endothelial ACE and only express renal ACE in tubular epithelial cells. The absence of endothelial ACE normalized the glomerular filtration rate and endothelial injury in diabetic ACE 3/9 mice. However, these mice developed tubular injury and albuminuria and displayed low renal levels of megalin that were similar to those observed in diabetic wild-type mice. In diabetic it-ACE mice, despite hyperfiltration, the absence of renal tubular ACE greatly reduced tubulointerstitial injury and albuminuria and increased renal megalin expression compared with diabetic wild-type and diabetic ACE 3/9 mice. These findings demonstrate that endothelial ACE is a central regulator of the glomerular filtration rate while tubular ACE is a key player in the development of tubular injury and albuminuria. These data suggest that tubular injury, rather than hyperfiltration, is the main cause of microalbuminuria in early diabetic nephropathy. PMID- 29187374 TI - Corrigendum. PMID- 29187373 TI - Klotho and activin A in kidney injury: plasma Klotho is maintained in unilateral obstruction despite no upregulation of Klotho biosynthesis in the contralateral kidney. AB - In a new paradigm of etiology related to chronic kidney disease-mineral and bone disorder (CKD-MBD), kidney injury may cause induction of factors in the injured kidney that are released into the circulation and thereby initiate and maintain renal fibrosis and CKD-MBD. Klotho is believed to ameliorate renal fibrosis and CKD-MBD, while activin A might have detrimental effects. The unilateral ureter obstruction (UUO) model is used here to examine this concept by investigating early changes related to renal fibrosis in the obstructed kidney, untouched contralateral kidney, and vasculature which might be affected by secreted factors from the obstructed kidney, and comparing with unilateral nephrectomized controls (UNX). Obstructed kidneys showed early Klotho gene and protein depletion, whereas plasma Klotho increased in both UUO and UNX rats, indicating an altered metabolism of Klotho. Contralateral kidneys had no compensatory upregulation of Klotho and maintained normal expression of the examined fibrosis-related genes, as did remnant UNX kidneys. UUO caused upregulation of transforming growth factor beta and induction of periostin and activin A in obstructed kidneys without changes in the contralateral kidneys. Plasma activin A doubled in UUO rats after 10 days while no changes were seen in UNX rats, suggesting secretion of activin A from the obstructed kidney with potentially systemic effects on CKD-MBD. As such, increased aortic sclerostin was observed in UUO rats compared with UNX and normal controls. The present results are in line with the new paradigm and show very early vascular effects of unilateral kidney fibrosis, supporting the existence of a new kidney-vasculature axis. PMID- 29187375 TI - Advances in the diagnosis and treatment of Von Willebrand disease. AB - Von Willebrand disease (VWD) is the most common inherited bleeding disorder, yet diagnosis and management remain challenging. Development and use of bleeding assessment tools allows for improved stratification of which patients may require further assessment and which patients are most likely to require treatment of their VWD. New options for laboratory assessment of von Willebrand factor (VWF) activity include a new platelet-binding assay, the VWF:GPIbM, which is subject to less variability than the ristocetin cofactor activity assay, and collagen binding assays that provide insight into a different function of VWF. Genetic testing may be helpful in some cases where a type 2 VWD variant is suspected but is usually not helpful in type 1 VWD. Finally, treatment options for VWD are reviewed, including the use of recombinant VWF. Despite these advances, still more work is required to improve diagnosis, treatment, and quality of life for affected patients. PMID- 29187378 TI - Platelet glycoprotein VI aids in local immunity during pneumonia-derived sepsis caused by gram-negative bacteria. AB - Platelet collagen receptor glycoprotein VI (GPVI) and podoplanin receptor C-type lectin-like receptor 2 (CLEC2) are receptors implicated in platelet activation that both signal via an immunoreceptor tyrosine-based activation motif. Platelets are necessary for host defense and prevention of hemorrhage during sepsis, but the role of platelet GPVI and CLEC2 herein is unknown. To investigate this, we infected mice depleted of platelet GPVI or CLEC2 by antibody treatment or GPVI-/- mice with the common human sepsis pathogen Klebsiella pneumoniae via the airways to induce pneumonia-derived sepsis. The GPVI ligand collagen and the CLEC2 ligand podoplanin were constitutively present in the lung, whereas the GPVI ligands fibrin and histone were induced during pneumonia. During late-stage infection, both mice depleted of GPVI and GPVI-/- mice showed increased bacterial growth in lungs, and GPVI-/- mice also showed increased bacterial growth in distant body sites. Despite higher bacterial loads, GPVI-depleted mice showed reduced platelet numbers, platelet activation, and platelet-leukocyte complex formation in the bronchoalveolar space. Consistently, in human whole blood, GPVI stimulation of platelets increased platelet-leukocyte complex formation and leukocyte activation, which was accompanied by enhanced phagocytosis of Klebsiella GPVI depleted mice showed increased lung hemorrhage during infection, but not to the extent observed in platelet-depleted mice, and lung bleeding was not significantly different between GPVI-/- and wild-type mice. CLEC2 depletion did not affect any of the responses during pneumonia. These results suggest that platelet GPVI, but not CLEC2, contributes to local host defense during pneumonia derived sepsis by enhancing leukocyte function.

AB - An activating mutation of Fms-like tyrosine kinase 3 (FLT3) is the most frequent genetic alteration associated with poor prognosis in acute myeloid leukemia (AML). Although many FLT3 inhibitors have been clinically developed, no first generation inhibitors have demonstrated clinical efficacy by monotherapy, due to poor pharmacokinetics or unfavorable safety profiles possibly associated with low selectivity against FLT3 kinase. Recently, a selective FLT3 inhibitor, quizartinib, demonstrated favorable outcomes in clinical studies. However, several resistant mutations emerged during the disease progression. To overcome these problems, we developed a novel FLT3 inhibitor, FF-10101, designed to possess selective and irreversible FLT3 inhibition. The co-crystal structure of FLT3 protein bound to FF-10101 revealed the formation of a covalent bond between FF-10101 and the cysteine residue at 695 of FLT3. The unique binding brought high selectivity and inhibitory activity against FLT3 kinase. FF-10101 showed potent growth inhibitory effects on human AML cell lines harboring FLT3 internal tandem duplication (FLT3-ITD), MOLM-13, MOLM-14, and MV4-11, and all tested types of mutant FLT3-expressing 32D cells including quizartinib-resistant mutations at D835, Y842, and F691 residues in the FLT3 kinase domain. In mouse subcutaneous implantation models, orally administered FF-10101 showed significant growth inhibitory effect on FLT3-ITD-D835Y- and FLT3-ITD-F691L-expressing 32D cells. Furthermore, FF-10101 potently inhibited growth of primary AML cells harboring either FLT3-ITD or FLT3-D835 mutation in vitro and in vivo. These results indicate that FF-10101 is a promising agent for the treatment of patients with AML with FLT3 mutations, including the activation loop mutations clinically identified as quizartinib-resistant mutations.

AB - Patients with sickle cell disease (SCD) suffer from intense pain that can start during infancy and increase in severity throughout life, leading to hospitalization and poor quality of life. A unique feature of SCD is vaso occlusive crises (VOCs) characterized by episodic, recurrent, and unpredictable episodes of acute pain. Microvascular obstruction during a VOC leads to impaired oxygen supply to the periphery and ischemia reperfusion injury, inflammation, oxidative stress, and endothelial dysfunction, all of which may perpetuate a noxious microenvironment leading to pain. In addition to episodic acute pain, patients with SCD also report chronic pain. Current treatment of moderate to severe pain in SCD is mostly reliant upon opioids; however, long-term use of opioids is associated with multiple side effects. This review presents up-to-date developments in our understanding of the pathobiology of pain in SCD. To help focus future research efforts, major gaps in knowledge are identified regarding how sickle pathobiology evokes pain, pathways specific to chronic and acute sickle pain, perception-based targets of "top-down" mechanisms originating from the brain and neuromodulation, and how pain affects the sickle microenvironment and pathophysiology. This review also describes mechanism-based targets that may help develop novel therapeutic and/or preventive strategies to ameliorate pain in SCD. PMID- 29187379 TI - Mutant JAK3 signaling is increased by loss of wild-type JAK3 or by acquisition of secondary JAK3 mutations in T-ALL. AB - The Janus kinase 3 (JAK3) tyrosine kinase is mutated in 10% to 16% of T-cell acute lymphoblastic leukemia (T-ALL) cases. JAK3 mutants induce constitutive JAK/STAT signaling and cause leukemia when expressed in the bone marrow cells of mice. Surprisingly, we observed that one third of JAK3-mutant T-ALL cases harbor 2 JAK3 mutations, some of which are monoallelic and others that are biallelic. Our data suggest that wild-type JAK3 competes with mutant JAK3 (M511I) for binding to the common gamma chain and thereby suppresses its oncogenic potential. We demonstrate that JAK3 (M511I) can increase its limited oncogenic potential through the acquisition of an additional mutation in the mutant JAK3 allele. These double JAK3 mutants show increased STAT5 activation and increased potential to transform primary mouse pro-T cells to interleukin-7-independent growth and were not affected by wild-type JAK3 expression. These data extend our insight into the oncogenic properties of JAK3 mutations and provide an explanation of why progression of JAK3-mutant T-ALL cases can be associated with the accumulation of additional JAK3 mutations. PMID- 29187380 TI - Nbeal2 interacts with Dock7, Sec16a, and Vac14. AB - Mutations in NBEAL2, the gene encoding the scaffolding protein Nbeal2, are causal of gray platelet syndrome (GPS), a rare recessive bleeding disorder characterized by platelets lacking alpha-granules and progressive marrow fibrosis. We present here the interactome of Nbeal2 with additional validation by reverse immunoprecipitation of Dock7, Sec16a, and Vac14 as interactors of Nbeal2. We show that GPS-causing mutations in its BEACH domain have profound and possible effects on the interaction with Dock7 and Vac14, respectively. Proximity ligation assays show that these 2 proteins are physically proximal to Nbeal2 in human megakaryocytes. In addition, we demonstrate that Nbeal2 is primarily localized in the cytoplasm and Dock7 on the membrane of or in alpha-granules. Interestingly, platelets from GPS cases and Nbeal2-/- mice are almost devoid of Dock7, resulting in a profound dysregulation of its signaling pathway, leading to defective actin polymerization, platelet activation, and shape change. This study shows for the first time proteins interacting with Nbeal2 and points to the dysregulation of the canonical signaling pathway of Dock7 as a possible cause of the aberrant formation of platelets in GPS cases and Nbeal2-deficient mice. PMID- 29187381 TI - CRRL269: a novel designer and renal-enhancing pGC-A peptide activator. AB - The natriuretic peptides (NPs) B-type NP (BNP) and urodilatin (URO) exert renal protective properties via the particulate guanylyl cyclase A receptor (pGC-A). As a potential renal-enhancing strategy, we engineered a novel designer peptide that we call CRRL269. CRRL269 was investigated in human cell lines and in normal canines to define potential cardiorenal enhancing actions. The mechanism of its cardiorenal selective properties was also investigated. In vitro NP receptor activity was quantified with guanosine 3',5'-cyclic monophosphate generation. In vivo effects were determined in normal canine acute infusion studies. We observed that CRRL269 demonstrated enhanced pGC-A activity in renal compared with nonrenal cell lines. CRRL269 exerted enhanced resistance to neprilysin compared with URO. Importantly, CRRL269 exhibited significant and greater increases in urinary sodium excretion and diuresis, with less blood pressure reduction, than BNP or URO in normal canines. CRRL269 retained potent renin-angiotensin-aldosterone system (RAAS) suppressing properties shared by URO and BNP. Also, CRRL269 exerted less arterial relaxation and higher cAMP cardiomyocytes generation than BNP. CRRL269 possessed superior renal and pGC-A activating properties compared with BNP or URO in vitro. CRRL269 exerted enhanced renal actions while suppressing RAAS in vivo and with less hypotension compared with URO or BNP. Together, our study suggests that CRRL269 is a promising innovative renal-enhancing drug, with favorable protective actions targeting cardiorenal disease states through the pGC A receptor. PMID- 29187383 TI - Mice lacking PKC-theta in skeletal muscle have reduced intramyocellular lipid accumulation and increased insulin responsiveness in skeletal muscle. AB - Protein kinase C-theta (PKC-theta) is a lipid-sensitive molecule associated with lipid-induced insulin resistance in skeletal muscle. Rodent models have not cohesively supported that PKC-theta impairs insulin responsiveness in skeletal muscle. The purpose of this study was to generate mice that lack PKC-theta in skeletal muscle and determine how lipid accumulation and insulin responsiveness are affected in that tissue. Mice lacking PKC-theta in skeletal muscle (SkMPKCthetaKO) and controls (SkMPKCthetaWT) were placed on a regular diet (RD) or high-fat diet (HFD) for 15 wk, followed by determination of food intake, fasting glucose levels, lipid accumulation, and insulin responsiveness. There were no differences between SkMPKCthetaWT and SkMPKCthetaKO mice on a RD. SkMPKCthetaKO mice on a HFD gained less weight from 10 through 15 wk of dietary intervention ( P < 0.05). This was likely due to less caloric consumption ( P = 0.0183) and fewer calories from fat ( P < 0.001) compared with SkMPKCthetaWT mice on a HFD. Intramyocellular lipid accumulation ( P < 0.0001), fatty acid binding protein 4, and TNF-alpha mRNA levels ( P < 0.05) were markedly reduced in SkMPKCthetaKO compared with SkMPKCthetaWT mice on a HFD. As a result, fasting hyperglycemia was mitigated and insulin responsiveness, as indicated by Akt phosphorylation, was maintained in SkMPKCthetaKO on a HFD. Liver lipid accumulation was not affected by genotype, suggesting the deletion of PKC-theta from skeletal muscle has a tissue-specific effect. PKC-theta is a regulator of lipid-induced insulin resistance in skeletal muscle. However, the effects of this mutation may be tissue specific. Further work is warranted to comprehensively evaluated whole body metabolic responses in this model. PMID- 29187382 TI - Opposing effects of bronchopulmonary C-fiber subtypes on cough in guinea pigs. AB - We have addressed the hypothesis that the opposing effects of bronchopulmonary C fiber activation on cough are attributable to the activation of C-fiber subtypes. Coughing was evoked in anesthetized guinea pigs by citric acid (0.001-2 M) applied topically in 100-ul aliquots to the tracheal mucosa. In control preparations, citric acid evoked 10 +/- 1 coughs cumulatively. Selective activation of the pulmonary C fibers arising from the nodose ganglia with either aerosols or continuous intravenous infusion of adenosine or the 5-HT3 receptor selective agonist 2-methyl-5-HT nearly abolished coughing evoked subsequently by topical citric acid challenge. Delivering adenosine or 2-methyl-5-HT directly to the tracheal mucosa (where few if any nodose C fibers terminate) was without effect on citric acid-evoked cough. These actions of pulmonary administration of adenosine and 2-methyl-5-HT were accompanied by an increase in respiratory rate, but it is unlikely that the change in respiratory pattern caused the decrease in coughing, as the rapidly adapting receptor stimulant histamine also produced a marked tachypnea but was without effect on cough. In awake guinea pigs, adenosine failed to evoke coughing but reduced coughing induced by the nonselective C-fiber stimulant capsaicin. We conclude that bronchopulmonary C-fiber subtypes in guinea pigs have opposing effects on cough, with airway C fibers arising from the jugular ganglia initiating and/or sensitizing the cough reflex and the intrapulmonary C fibers arising from the nodose ganglia actively inhibiting cough upon activation. PMID- 29187384 TI - Role of Depression and Social Isolation at Time of Waitlisting for Survival 8 Years After Heart Transplantation. AB - BACKGROUND: We evaluated depression and social isolation assessed at time of waitlisting as predictors of survival in heart transplant (HTx) recipients. METHODS AND RESULTS: Between 2005 and 2006, 318 adult HTx candidates were enrolled in the Waiting for a New Heart Study, and 164 received transplantation. Patients were followed until February 2013. Psychosocial characteristics were assessed by questionnaires. Eurotransplant provided medical data at waitlisting, transplantation dates, and donor characteristics; hospitals reported medical data at HTx and date of death after HTx. During a median follow-up of 70 months (<1-93 months post-HTx), 56 (38%) of 148 transplanted patients with complete data died. Depression scores were unrelated to social isolation, and neither correlated with disease severity. Higher depression scores increased the risk of dying (hazard ratio=1.07, 95% confidence interval, 1.01, 1.15, P=0.032), which was moderated by social isolation scores (significant interaction term; hazard ratio = 0.985, 95% confidence interval, 0.973, 0.998; P=0.022). These findings were maintained in multivariate models controlling for covariates (P values 0.020-0.039). Actuarial 1-year/5-year survival was best for patients with low depression who were not socially isolated at waitlisting (86% after 1 year, 79% after 5 years). Survival of those who were either depressed, or socially isolated or both, was lower, especially 5 years posttransplant (56%, 60%, and 62%, respectively). CONCLUSIONS: Low depression in conjunction with social integration at time of waitlisting is related to enhanced chances for survival after HTx. Both factors should be considered for inclusion in standardized assessments and interventions for HTx candidates. PMID- 29187385 TI - National Trends in Admission and In-Hospital Mortality of Patients With Heart Failure in the United States (2001-2014). AB - BACKGROUND: To investigate heart failure (HF) hospitalization trends in the United States and change in trends after publication of management guidelines. METHODS AND RESULTS: Using data from the National Inpatient Sample and the US Census Bureau, annual national estimates in HF admissions and in-hospital mortality were estimated for years 2001 to 2014, during which an estimated 57.4 million HF-associated admissions occurred. Rates (95% confidence intervals) of admissions and in-hospital mortality among primary HF hospitalizations declined by an average annual rate of 3% (2.5%-3.5%) and 3.5% (2.9%-4.0%), respectively. Compared with 2001 to 2005, the average annual rate of decline in primary HF admissions was more in 2006 to 2009 (ie, 3.4% versus 1.1%; P=0.02). In 2010 to 2014, primary HF admission continued to decline by an average annual rate of 4.3% (95% confidence interval, 3.9%-5.1%), but this was not significantly different from 2006 to 2009 (P=0.14). In contrast, there was no further decline in in hospital mortality trend after the guideline-release years. For hospitalizations with HF as the secondary diagnosis, there was an upward trend in admissions in 2001 to 2005. However, the trend began to decline in 2006 to 2009, with an average annual rate of 2.4% (95% confidence interval, 0.8%-4%). Meanwhile, there was a consistent decline in in-hospital mortality by an average annual rate of 3.7% (95% confidence interval, 3.3%-4.2%) during the study period, but the decline was more in 2006 to 2009 compared with 2001 to 2005 (ie, 5.4% versus 3.4%; P<0.001). Beyond 2009, admission and in-hospital mortality rates continued to decline, although this was not significantly better than the preceding interval. CONCLUSIONS: From 2001 to 2014, HF admission and in-hospital mortality rates declined significantly in the United States; the greatest improvements coincided with the publication of the 2005 American College of Cardiology/American Heart Association HF guidelines. PMID- 29187386 TI - High Incidence of Atrial Fibrillation After Embolic Stroke of Undetermined Source in Posterior Cerebral Artery Territory. AB - BACKGROUND: Subclinical atrial fibrillation is one possible cause of embolic stroke of undetermined source (ESUS). It remains to be elucidated if a specific infarction site has a predictive value for detecting subclinical atrial fibrillation. We aimed to investigate the predictive value of infarction site in patients with ESUS for the detection of atrial tachyarrhythmia (AT) using an insertable cardiac monitor. METHODS AND RESULTS: Consecutive 146 patients (84 men; aged 62+/-12 years) underwent insertable cardiac monitor implantation after diagnosis of ESUS. The detection of AT >30 seconds was evaluated. The ESUS infarction sites were categorized into internal carotid artery and vertebral artery (VA) territories, with ophthalmic artery, anterior cerebral artery, and middle cerebral artery as internal carotid artery subterritories, and posterior cerebral artery and other vertebrobasilar arteries as VA subterritories. During a median follow-up of 387 days, AT was detected in 33 patients (23%). Subclinical AT detection was significantly more frequent after VA territorial infarction opposed to internal carotid artery infarction (20/57 [35%] versus 13/89 [15%]; P=0.0039). Kaplan-Meier analysis demonstrated a significantly higher AT detection rate after VA infarction (log-rank, P=0.0076). Regression analysis revealed that VA territorial infarction, and particularly posterior cerebral artery area infarction, was an independent predictor of AT detection. CONCLUSIONS: Patients with ESUS in the posterior cerebral artery territory had a higher rate of subclinical AT detection than those with other infarct localizations. Our data suggest that the possible usefulness of ESUS site to identify candidates for direct oral anticoagulation should be confirmed in future research. PMID- 29187387 TI - Prognostic Value of Serial Galectin-3 Measurements in Patients With Acute Heart Failure. AB - BACKGROUND: Several clinical studies have evaluated the association between galectin-3 levels and outcome in patients with heart failure (HF). However, little is known about the predictive value of repeated galectin-3 measurements. This study evaluates the prognostic value of repeated time-dependent galectin-3 measurements in acute HF patients. METHODS AND RESULTS: In the TRIUMPH (Translational Initiative on Unique and Novel Strategies for Management of Patients with Heart Failure) clinical cohort study, 496 acute HF patients were enrolled in 14 hospitals in The Netherlands, between 2009 and 2014. Repeated blood samples (7) were drawn during 1-year follow-up. Associations between repeated biomarker measurements and the primary end point were assessed using a joint model. Median age was 74 years and 37% were women. The primary end point, composite of all-cause mortality and HF rehospitalization, was reached in 188 patients (40%), during a median follow-up of 325 days (interquartile range 85 401). The median baseline galectin-3 level was 24 ng/mL (interquartile range 18 34). The mean number of galectin-3 measurements available per patient was 4.3. After adjustment for clinical factors and N-terminal pro-brain natriuretic peptide, there was a weak association between baseline galectin-3 and risk of the primary end point. When repeated measurements were taken into account, the adjusted hazard ratio per 1 SD increase of the galectin-3 level (on the log2 scale) at any time point increased to 1.67 (95% confidence interval, 1.24-2.23, P<0.001). After additional adjustment for repeated N-terminal pro-brain natriuretic peptide measurements, the association remained statistically significant. CONCLUSIONS: Repeated galectin-3 measurements appeared to be a strong predictor of outcome in acute HF patients, independent of N-terminal pro brain natriuretic peptide. Hence, galectin-3 may be helpful in clinical practice for prognostication and treatment monitoring. PMID- 29187388 TI - Effects of Dark Chocolate and Almonds on Cardiovascular Risk Factors in Overweight and Obese Individuals: A Randomized Controlled-Feeding Trial. AB - BACKGROUND: Consumption of almonds or dark chocolate and cocoa has favorable effects on markers of coronary heart disease; however, the combined effects have not been evaluated in a well-controlled feeding study. The aim of this study was to examine the individual and combined effects of consumption of dark chocolate and cocoa and almonds on markers of coronary heart disease risk. METHODS AND RESULTS: A randomized controlled, 4-period, crossover, feeding trial was conducted in overweight and obese individuals aged 30 to 70 years. Forty-eight participants were randomized, and 31 participants completed the entire study. Each diet period was 4 weeks long, followed by a 2-week compliance break. Participants consumed each of 4 isocaloric, weight maintenance diets: (1) no treatment foods (average American diet), (2) 42.5 g/d of almonds (almond diet [ALD]), (3) 18 g/d of cocoa powder and 43 g/d of dark chocolate (chocolate diet [CHOC]), or (4) all 3 foods (CHOC+ALD). Compared with the average American diet, total cholesterol, non-high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol after the ALD were lower by 4%, 5%, and 7%, respectively (P<0.05). The CHOC+ALD decreased apolipoprotein B by 5% compared with the average American diet. For low-density lipoprotein subclasses, compared with the average American diet, the ALD showed a greater reduction in large buoyant low-density lipoprotein particles (-5.7+/-2.3 versus -0.3+/-2.3 mg/dL; P=0.04), whereas the CHOC+ALD had a greater decrease in small dense low-density lipoprotein particles (-12.0+/-2.8 versus -5.3+/-2.8 mg/dL; P=0.04). There were no significant differences between diets for measures of vascular health and oxidative stress. CONCLUSIONS: Our results demonstrate that consumption of almonds alone or combined with dark chocolate under controlled-feeding conditions improves lipid profiles. Incorporating almonds, dark chocolate, and cocoa into a typical American diet without exceeding energy needs may reduce the risk of coronary heart disease.

PMID- 29187389 TI - Value of Excess Pressure Integral for Predicting 15-Year All-Cause and Cardiovascular Mortalities in End-Stage Renal Disease Patients. AB - BACKGROUND: The excess pressure integral (XSPI), derived from analysis of the arterial pressure curve, may be a significant predictor of cardiovascular events in high-risk patients. We comprehensively investigated the prognostic value of XSPI for predicting long-term mortality in end-stage renal disease patients undergoing regular hemodialysis. METHODS AND RESULTS: A total of 267 uremic patients (50.2% female; mean age 54.2+/-14.9 years) receiving regular hemodialysis for more than 6 months were enrolled. Cardiovascular parameters were obtained by echocardiography and applanation tonometry. Calibrated carotid arterial pressure waveforms were analyzed according to the wave-transmission and reservoir-wave theories. Multivariable Cox proportional hazard models were constructed to account for age, sex, diabetes mellitus, albumin, body mass index, and hemodialysis treatment adequacy. Incremental utility of the parameters to risk stratification was assessed by net reclassification improvement. During a median follow-up of 15.3 years, 124 deaths (46.4%) incurred. Baseline XSPI was significantly predictive of all-cause (hazard ratio per 1 SD 1.4, 95% confidence interval 1.15-1.70, P=0.0006) and cardiovascular mortalities (1.47, 1.18-1.84, P=0.0006) after accounting for the covariates. The addition of XSPI to the base prognostic model significantly improved prediction of both all-cause mortality (net reclassification improvement=0.1549, P=0.0012) and cardiovascular mortality (net reclassification improvement=0.1535, P=0.0033). XSPI was superior to carotid pulse wave velocity, forward and backward wave amplitudes, and left ventricular ejection fraction in consideration of overall independent and incremental prognostics values. CONCLUSIONS: In end-stage renal disease patients undergoing regular hemodialysis, XSPI was significantly predictive of long-term mortality and demonstrated an incremental value to conventional prognostic factors. PMID- 29187390 TI - Phenotyping of Sleep-Disordered Breathing in Patients With Chronic Heart Failure With Reduced Ejection Fraction-the SchlaHF Registry. AB - BACKGROUND: Different sleep-disordered breathing (SDB) phenotypes, including coexisting obstructive and central sleep apnea (OSA-CSA), have not yet been characterized in a large sample of patients with heart failure and reduced ejection fraction (HFrEF) receiving guideline-based therapies. Therefore, the aim of the present study was to determine the proportion of OSA, CSA, and OSA-CSA, as well as periodic breathing, in HFrEF patients with SDB. METHODS AND RESULTS: The German SchlaHF registry enrolled patients with HFrEF receiving guideline-based therapies, who underwent portable SDB monitoring. Polysomnography (n=2365) was performed in patients with suspected SDB. Type of SDB (OSA, CSA, or OSA-CSA), the occurrence of periodic breathing (proportion of Cheyne-Stokes respiration >=20%), and blood gases were determined in 1557 HFrEF patients with confirmed SDB. OSA, OSA-CSA, and CSA were found in 29%, 40%, and 31% of patients, respectively; 41% showed periodic breathing. Characteristics differed significantly among SDB groups and in those with versus without periodic breathing. There was a relationship between greater proportions of CSA and the presence of periodic breathing. Risk factors for having CSA rather than OSA were male sex, older age, presence of atrial fibrillation, lower ejection fraction, and lower awake carbon dioxide pressure (pco2). Periodic breathing was more likely in men, patients with atrial fibrillation, older patients, and as left ventricular ejection fraction and awake pco2 decreased, and less likely as body mass index increased and minimum oxygen saturation decreased. CONCLUSIONS: SchlaHF data show that there is wide interindividual variability in the SDB phenotype of HFrEF patients, suggesting that individualized management is appropriate. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov/. Unique identifier: NCT01500759. PMID- 29187391 TI - Implicit Gender Bias and the Use of Cardiovascular Tests Among Cardiologists. AB - BACKGROUND: Physicians' gender bias may contribute to gender disparities in cardiovascular testing. We used the Implicit Association Test to examine the association of implicit gender biases with decisions to use cardiovascular tests. METHODS AND RESULTS: In 2014, cardiologists completed Implicit Association Tests and a clinical vignette with patient gender randomly assigned. The Implicit Association Tests measured implicit gender bias for the characteristics of strength and risk taking. The vignette represented an intermediate likelihood of coronary artery disease regardless of patient gender: chest pain (part 1) followed by an abnormal exercise treadmill test (part 2). Cardiologists rated the likelihood of coronary artery disease and the usefulness of stress testing and angiography for the assigned patient. Of the 503 respondents (9.3% of eligible; 87% male, median age of 45 years, 58% in private practice), the majority associated strength or risk taking implicitly with male more than female patients. The estimated likelihood of coronary artery disease for both parts of the vignette was similar by patient gender. The utility of secondary stress testing after an abnormal exercise treadmill test was rated as "high" more often for female than male patients (32.8% versus 24.3%, P=0.04); this difference did not vary with implicit bias. Angiography was more consistently rated as having "high" utility for male versus female patients (part 1: 19.7% versus 9.8%; part 2: 73.7% versus 64.3%; P<0.05 for both); this difference was larger for cardiologists with higher implicit gender bias on risk taking (P=0.01). CONCLUSIONS: Cardiologists have varying degrees of implicit gender bias. This bias explained some, but not all, of the gender variability in simulated clinical decision-making for suspected coronary artery disease. PMID- 29187392 TI - Visit-to-Visit Variability of Fasting Plasma Glucose and the Risk of Cardiovascular Disease and All-Cause Mortality in the General Population. AB - BACKGROUND: The association of short-term variability of fasting plasma glucose (FPG) and mortality has been well investigated. However, the relationships between visit-to-visit variability of FPG over longer periods of follow-up and cardiovascular disease (CVD) and all-cause mortality are unclear. This study aimed to investigate these relationships. METHODS AND RESULTS: The current analysis included 53 607 Chinese participants (mean age, 49.10 years) who were free of CVD in the Kailuan study. Participants were divided into 4 categories by quartiles of visit-to-visit variability of FPG. Visit-to-visit variability of FPG was defined as the coefficient of variation of 3 values of FPG that were measured from the examination periods of 2006 to 2007, 2008 to 2009, and 2010 to 2011. Cox proportional hazards models were used to calculate hazard ratios and 95% confidence intervals for CVD and all-cause mortality. After a mean follow-up of 4.93 years, 4261 individuals developed CVD and 1545 individuals died. The incidence of CVD and all-cause mortality was 5.04 and 5.85 per 1000 person-years, respectively. After adjusting for mean FPG and other potential confounders, individuals in the highest quartile of variability of FPG compared with participants in the lowest quartile showed a 26% greater risk of developing CVD (hazard ratio, 1.26; 95% confidence interval, 1.08-1.47) and a 46% greater risk for all-cause mortality (hazard ratio, 1.46; 95% confidence interval, 1.25-1.70). CONCLUSIONS: Independent of mean FPG and other baseline parameters, elevated visit-to-visit variability of FPG significantly increases the risk of CVD and all cause mortality in the general population. Measuring long-term visit-to-visit variability of FPG is helpful for predicting the risk for CVD and all-cause mortality. PMID- 29187393 TI - Outcomes of Children and Adolescents with Advanced Hereditary Medullary Thyroid Carcinoma Treated with Vandetanib. AB - Purpose: Vandetanib is well-tolerated in patients with advanced medullary thyroid carcinoma (MTC). Long-term outcomes and mechanisms of MTC progression have not been reported previously.Experimental Design: We monitored toxicities and disease status in patients taking vandetanib for hereditary, advanced MTC. Tumor samples were analyzed for molecular mechanisms of disease progression.Results: Seventeen patients [8 male, age 13 (9-17)* years] enrolled; 16 had a RET p.Met918Thr germline mutation. The duration of vandetanib therapy was 6.1 (0.1-9.7+)* years with treatment ongoing in 9 patients. Best response was partial response in 10, stable disease in 6, and progressive disease in one patient. Duration of response was 7.4 (0.6-8.7+)* and 4.9 (0.6-7.8+)* years in patients with PR and SD, respectively. Six patients died 2.0 (0.4-5.7)* years after progression. Median progression-free survival (PFS) was 6.7 years [95% confidence interval (CI): 2.3 years-undefined] and 5-year overall survival (OS) was 88.2% (95% CI: 60.6% 96.9%). Of 16 patients with a RET p.Met918Thr mutation, progression-free survival was 6.7 years (95% CI: 3.1-undefined) and 5-year overall survival was 93.8% (95% CI: 63.2%-99.1%). No patients terminated treatment because of toxicity. DNA sequencing of tissue samples (n = 11) identified an increase in copy number alterations across the genome as a potential mechanism of drug resistance [*median (range)].Conclusions: This study demonstrates that vandetanib is safe and results in sustained responses in children and adolescents with hereditary MTC. Our preliminary molecular data suggest that an increase in copy number abnormalities may be associated with tumor progression in hereditary MTC patients treated with vandetanib.

AB - We are far away from the days when tuberculosis (TB) accounted for 1 in 4 deaths during the 19th century. However, Mycobacterium tuberculosis complex (MTBC) strains are still the leading cause of morbidity and mortality by a single infectious disease, with 9.6 million cases and 1.5 million deaths reported. One third of the world's population is estimated by the WHO to be infected with latent TB. During the last decade, several studies have aimed to define the characteristics of dormant bacteria in these latent infections. General features of the shift to a dormant state encompass several phenotypic changes that reduce metabolic activity. This low metabolic state is thought to increase the resistance of MTBC strains to host/environmental stresses, including antibiotic action. Once the stress ceases (e.g., interruption of treatment), dormant cells can reactivate and cause symptomatic disease again. Therefore, a proper understanding of dormancy could guide the rational development of new treatment regimens that target dormant cells, reducing later relapse. Here, we briefly summarize the latest data on the genetics involved in the regulation of dormancy and discuss new approaches to TB treatment. PMID- 29187394 TI - Carrion's Disease: the Sound of Silence. AB - Carrion's disease (CD) is a neglected biphasic vector-borne illness related to Bartonella bacilliformis. It is found in the Andean valleys and is transmitted mainly by members of the Lutzomyia genus but also by blood transfusions and from mother to child. The acute phase, Oroya fever, presents severe anemia and fever. The lethality is high in the absence of adequate treatment, despite the organism being susceptible to most antibiotics. Partial immunity is developed after infection by B. bacilliformis, resulting in high numbers of asymptomatic carriers. Following infection there is the chronic phase, Peruvian warts, involving abnormal proliferation of the endothelial cells. Despite potentially being eradicable, CD has been expanded due to human migration and geographical expansion of the vector. Moreover, in vitro studies have demonstrated the risk of the development of antimicrobial resistance. These findings, together with the description of new Bartonella species producing CD-like infections, the presence of undescribed potential vectors in new areas, the lack of adequate diagnostic tools and knowledge of the immunology and bacterial pathogenesis of CD, and poor international visibility, have led to the risk of increasing the potential expansion of resistant strains which will challenge current treatment schemes as well as the possible appearance of CD in areas where it is not endemic.

AB - Cancer is the second leading cause of death among American Indians and Alaskan Natives (AIAN), although cancer survival information in this population is limited, particularly among urban AIAN. In this retrospective cohort study, we compared all-cause and prostate, breast, lung, and colorectal cancer-specific mortality among AIAN (n = 582) and non-Hispanic white (NHW; n = 82,696) enrollees of Kaiser Permanente Northern California (KPNC) diagnosed with primary invasive breast, prostate, lung, or colorectal cancer from 1997 to 2015. Tumor registry and other electronic health records provided information on sociodemographic, comorbidity, tumor, clinical, and treatment characteristics. Cox regression models were used to estimate adjusted survival curves and hazard ratios (HR) with 95% confidence intervals (CI). AIAN had a significantly higher comorbidity burden compared with NHW (P < 0.05). When adjusting for patient, disease characteristics, and Charlson comorbidity scores, all-cause mortality and cancer specific mortality were significantly higher for AIAN than NHW patients with breast cancer (HR, 1.47; 95% CI, 1.13-1.92) or with prostate cancer (HR, 1.87; 95% CI, 1.14-3.06) but not for AIAN patients with lung and colorectal cancer. Despite approximately equal access to preventive services and cancer care in this setting, we found higher mortality for AIAN than NHW with some cancers, and a greater proportion of AIAN cancer patients with multiple comorbid conditions. This study provides severely needed information on the cancer experience of the 71% of AIANs who live in urban areas and access cancer care outside of the Indian Health Services, from which the vast majority of AIAN cancer information comes.

AB - The nuclear receptor PPAR-beta/delta (PPARD) has essential roles in fatty acid catabolism and energy homeostasis as well as cell differentiation, inflammation, and metabolism. However, its contributions to tumorigenesis are uncertain and have been disputed. Here, we provide evidence of tumor suppressive activity of PPARD in prostate cancer through a noncanonical and ligand-independent pathway. PPARD was downregulated in prostate cancer specimens. In murine prostate epithelium, PPARD gene deletion resulted in increased cellularity. Genetic modulation of PPARD in human prostate cancer cell lines validated the tumor suppressive activity of this gene in vitro and in vivo Mechanistically, PPARD exerted its activity in a DNA binding-dependent and ligand-independent manner. We identified a novel set of genes repressed by PPARD that failed to respond to ligand-mediated activation. Among these genes, we observed robust regulation of the secretory trefoil factor family (TFF) members, including a causal and correlative association of TFF1 with prostate cancer biology in vitro and in patient specimens. Overall, our results illuminate the oncosuppressive function of PPARD and understanding of the pathogenic molecular pathways elicited by this nuclear receptor.Significance: These findings challenge the presumption that the function of the nuclear receptor PPARbeta/delta in cancer is dictated by ligand mediated activation.

PMID- 29187396 TI - Recombinant Endolysins as Potential Therapeutics against Antibiotic-Resistant Staphylococcus aureus: Current Status of Research and Novel Delivery Strategies. AB - Staphylococcus aureus is one of the most common pathogens of humans and animals, where it frequently colonizes skin and mucosal membranes. It is of major clinical importance as a nosocomial pathogen and causative agent of a wide array of diseases. Multidrug-resistant strains have become increasingly prevalent and represent a leading cause of morbidity and mortality. For this reason, novel strategies to combat multidrug-resistant pathogens are urgently needed. Bacteriophage-derived enzymes, so-called endolysins, and other peptidoglycan hydrolases with the ability to disrupt cell walls represent possible alternatives to conventional antibiotics. These lytic enzymes confer a high degree of host specificity and could potentially replace or be utilized in combination with antibiotics, with the aim to specifically treat infections caused by Gram positive drug-resistant bacterial pathogens such as methicillin-resistant S. aureus. LysK is one of the best-characterized endolysins with activity against multiple staphylococcal species. Various approaches to further enhance the antibacterial efficacy and applicability of endolysins have been demonstrated. These approaches include the construction of recombinant endolysin derivatives and the development of novel delivery strategies for various applications, such as the production of endolysins in lactic acid bacteria and their conjugation to nanoparticles. These novel strategies are a major focus of this review. PMID- 29187401 TI - Delivering Type I Interferon to Dendritic Cells Empowers Tumor Eradication and Immune Combination Treatments. AB - An ideal generic cancer immunotherapy should mobilize the immune system to destroy tumor cells without harming healthy cells and remain active in case of recurrence. Furthermore, it should preferably not rely on tumor-specific surface markers, as these are only available in a limited set of malignancies. Despite approval for treatment of various cancers, clinical application of cytokines is still impeded by their multiple toxic side effects. Type I IFN has a long history in the treatment of cancer, but its multifaceted activity pattern and complex side effects prevent its clinical use. Here we develop AcTakines (Activity-on Target cytokines), optimized (mutated) immunocytokines that are up to 1,000-fold more potent on target cells, allowing specific signaling in selected cell types only. Type I IFN-derived AcTaferon (AFN)-targeting Clec9A+ dendritic cells (DC) displayed strong antitumor activity in murine melanoma, breast carcinoma, and lymphoma models and against human lymphoma in humanized mice without any detectable toxic side effects. Combined with immune checkpoint blockade, chemotherapy, or low-dose TNF, complete tumor regression and long-lasting tumor immunity were observed, still without adverse effects. Our findings indicate that DC-targeted AFNs provide a novel class of highly efficient, safe, and broad spectrum off-the-shelf cancer immunotherapeutics with no need for a tumor marker.Significance: Targeted type I interferon elicits powerful antitumor efficacy, similar to wild-type IFN, but without any toxic side effects.

AB - Brachyspira pilosicoli is a slow-growing anaerobic spirochete that colonizes the large intestine. Colonization occurs commonly in pigs and adult chickens, causing colitis/typhlitis, diarrhea, poor growth rates, and reduced production. Colonization of humans also is common in some populations (individuals living in village and peri-urban settings in developing countries, recent immigrants from developing countries, homosexual males, and HIV-positive patients), but the spirochete rarely is investigated as a potential human enteric pathogen. In part this is due to its slow growth and specialized growth requirements, meaning that it is not detectable in human fecal samples using routine diagnostic methods. Nevertheless, it has been identified histologically attached to the colon and rectum in patients with conditions such as chronic diarrhea, rectal bleeding, and/or nonspecific abdominal discomfort, and one survey of Australian Aboriginal children showed that colonization was significantly associated with failure to thrive. B. pilosicoli has been detected in the bloodstream of elderly patients or individuals with chronic conditions such as alcoholism and malignancies. This review describes the spirochete and associated diseases. It aims to encourage clinicians and clinical microbiologists to consider B. pilosicoli in their differential diagnoses and to develop and use appropriate diagnostic protocols to identify the spirochete in clinical specimens. PMID- 29187402 TI - The E3 Ligase RING1 Targets p53 for Degradation and Promotes Cancer Cell Proliferation and Survival. AB - As a component of the transcriptional repression complex 1 (PRC1), the ring finger protein RING1 participates in the epigenetic regulation in cancer. However, the contributions of RING1 to cancer etiology or development are unknown. In this study, we report that RING1 is a critical negative regulator of p53 homeostasis in human hepatocellular and colorectal carcinomas. RING1 acts as an E3 ubiquitin (Ub) ligase to directly interact with and ubiquitinate p53, resulting in its proteasome-dependent degradation. The RING domain of RING1 was required for its E3 Ub ligase activity. RING1 depletion inhibited the proliferation and survival of the p53 wild-type cancer cells by inducing cell cycle arrest, apoptosis, and senescence, with only modest effects on p53 deficient cells. Its growth inhibitory effect was partially rescued by p53 silencing, suggesting an important role for the RING1-p53 complex in human cancer. In clinical specimens of hepatocellular carcinoma, RING1 upregulation was evident in association with poor clinical outcomes. Collectively, our results elucidate a novel PRC1-independent function of RING1 and provide a mechanistic rationale for its candidacy as a new prognostic marker and/or therapeutic target in human cancer.Significance: These results elucidate a novel PRC1-independent function of RING1 and provide a mechanistic rationale for its candidacy as a new prognostic marker and/or therapeutic target in human cancer.

AB - Physiologic barriers to drug delivery and selection for drug resistance limit survival outcomes in cancer patients. In this study, we present preclinical evidence that a subtumoricidal photodynamic priming (PDP) strategy can relieve drug delivery barriers in the tumor microenvironment to safely widen the therapeutic window of a nanoformulated cytotoxic drug. In orthotopic xenograft models of pancreatic cancer, combining PDP with nanoliposomal irinotecan (nal IRI) prevented tumor relapse, reduced metastasis, and increased both progression free survival and 1-year disease-free survival. PDP enabled these durable improvements by targeting multiple tumor compartments to (i) increase intratumoral drug accumulation by >10-fold, (ii) increase the duration of drug exposure above a critical therapeutic threshold, and (iii) attenuate surges in CD44 and CXCR4 expression, which mediate chemoresistance often observed after multicycle chemotherapy. Overall, our results offer preclinical proof of concept for the effectiveness of PDP to minimize risks of tumor relapse, progression, and drug resistance and to extend patient survival.Significance: A biophysical priming approach overcomes key treatment barriers, significantly reduces metastases, and prolongs survival in orthotopic models of human pancreatic cancer.

AB - Epithelial ovarian cancer (EOC) is the most lethal gynecologic malignancy, but it still lacks effective treatment options. In this study, we utilized proteomic technology to identify lipolysis-stimulated lipoprotein receptor (LSR) as a new tumor antigen of EOC. Immunohistochemical analysis of EOC tissues in conjunction with survival analysis of EOC patients showed that high expression of LSR is associated with poor prognosis. High LSR expression also occurred in tumor metastases including to the lymph node and omentum. To evaluate the possible benefits of blocking this antigen in EOC, we raised a new monoclonal antibody (mAb) to human LSR (hLSR). In mouse xenograft models of hLSR+ EOC (cell lines or patient-derived tumors), we found that administration of anti-hLSR mAb inhibited tumor growth in a manner independent of both antibody-dependent cellular cytotoxicity and complement-dependent cytotoxicity. Mechanistic investigations showed that hLSR expression increased incorporation of very-low-density lipoprotein (VLDL) into EOC cells and that anti-hLSR mAb inhibited lipid uptake in vitro and in vivo Moreover, VLDL promoted cell proliferation in hLSR-positive EOC cells in vitro, and this effect was inhibited by anti-hLSR mAb. While the anti-hLSR mAb studied cross reacted with the mouse antigen, we observed no adverse effects on normal organs and lipid metabolism in murine hosts. Our findings suggest that hLSR plays a key functional role in EOC development and that this antigen can be therapeutically targeted by specific mAb to improve EOC treatment.Significance: These findings offer preclinical evidence of the therapeutic efficacy of a novel targeted antibody therapy against deadly epithelial ovarian cancers.

AB - Studies of the estrogen receptor (ER) coactivator protein Mediator subunit 1 (MED1) have revealed its specific roles in pubertal mammary gland development and potential contributions to breast tumorigenesis, based on coamplification of MED1 and HER2 in certain breast cancers. In this study, we generated a mouse model of mammary tumorigenesis harboring the MMTV-HER2 oncogene and mutation of MED1 to evaluate its role in HER2-driven tumorigenesis. MED1 mutation in its ER interacting LxxLL motifs was sufficient to delay tumor onset and to impair tumor growth, metastasis, and cancer stem-like cell formation in this model. Mechanistic investigations revealed that MED1 acted directly to regulate ER signaling through the downstream IGF1 pathway but not the AREG pathway. Our findings show that MED1 is critical for HER2-driven breast tumorigenesis, suggesting its candidacy as a disease-selective therapeutic target.Significance: These findings identify an estrogen receptor-binding protein as a critical mediator of HER2-driven breast tumorigenesis, suggesting its candidacy as a disease-selective therapeutic target.

AB - The RNA polypyrimidine tract-binding protein PTBP3 is a little studied paralog of PTBP1, which has oncogenic properties. In this study, we demonstrate that PTBP3 induces epithelial-mesenchymal transition (EMT) in breast tumor cells and promotes their invasive growth and metastasis. Elevated expression of PTBP3 associated significantly with lymph node metastasis, advanced histology grade, TNM stage, and poor 5-year overall survival of patients. In human mammary epithelial cells, PTBP3 overexpression was sufficient to induce EMT and to enhance cell migration, invasion, and cancer stem-like cell properties. PTBP3 regulated expression of the EMT regulatory transcription factor ZEB1 by binding the 3'UTR of its mRNA, thereby preventing its degradation. Conversely, ZEB1 ablation blocked the ability of PTBP3 to induce EMT. Overall, our findings define PTBP3 as a regulator of EMT that acts by governing expression of ZEB1, and they establish an oncogenic function of PTBP3, suggesting its candidacy as a theranostic target.Significance: These findings define PTBP3 as a regulator of EMT that acts by governing expression of ZEB1, and they establish an oncogenic function of PTBP3, suggesting its candidacy as a theranostic target.

AB - Increasing evidence shows that tumor clonal architectures are often the consequence of a complex branching process, yet little is known about the expected dynamics and extent to which these divergent subclonal expansions occur. Here, we develop and implement more than 88,000 instances of a stochastic evolutionary model simulating genetic drift and neoplastic progression. Under different combinations of population genetic parameter values, including those estimated for colorectal cancer and glioblastoma multiforme, the distribution of sizes of subclones carrying driver mutations had a heavy right tail at the time of tumor detection, with only 1 to 4 dominant clones present at >=10% frequency. In contrast, the vast majority of subclones were present at <10% frequency, many of which had higher fitness than currently dominant clones. The number of dominant clones (>=10% frequency) in a tumor correlated strongly with the number of subclones (<10% of the tumor). Overall, these subclones were frequently below current standard detection thresholds, frequently harbored treatment-resistant mutations, and were more common in slow-growing tumors.Significance: The model presented in this paper addresses tumor heterogeneity by framing expectations for the number of resistant subclones in a tumor, with implications for future studies of the evolution of therapeutic resistance.

AB - OBJECTIVES: Over two million people in the UK are living with and beyond cancer. A third report diminished quality of life. DESIGN: A review of published systematic reviews to identify effective non-pharmacological interventions to improve the quality of life of cancer survivors. DATA SOURCES: Databases searched until May 2017 included PubMed, Cochrane Central, EMBASE, MEDLINE, Web of Science, the Cumulative Index to Nursing and Allied Health Literature, and PsycINFO. STUDY SELECTION: Published systematic reviews of randomised trials of non-pharmacological interventions for people living with and beyond cancer were included; included reviews targeted patients aged over 18. All participants had already received a cancer diagnosis. Interventions located in any healthcare setting, home or online were included. Reviews of alternative therapies or those non-English reports were excluded. Two researchers independently assessed titles, abstracts and the full text of papers, and independently extracted the data. OUTCOMES: The primary outcome of interest was any measure of global (overall) quality of life. ANALYTICAL METHODS: Quality assessment assessing methdological quality of systematic reviews (AMSTAR) and narrative synthesis, evaluating effectiveness of non-pharmacological interventions and their components. RESULTS: Of 14 430 unique titles, 21 were included in the review of reviews. There was little overlap in the primary papers across these reviews. Thirteen reviews covered mixed tumour groups, seven focused on breast cancer and one focused on prostate cancer. Face-to-face interventions were often combined with online, telephone and paper-based reading materials. Interventions included physical, psychological or behavioural, multidimensional rehabilitation and online approaches. Yoga specifically, physical exercise more generally, cognitive behavioural therapy (CBT) and mindfulness-based stress reduction (MBSR) programmes showed benefit in terms of quality of life. CONCLUSIONS: Exercise based interventions were effective in the short (less than 3-8 months) and long term. CBT and MBSR also showed benefits, especially in the short term. The evidence for multidisciplinary, online and educational interventions was equivocal. PMID- 29187409 TI - Study of depression influencing factors with zero-inflated regression models in a large-scale population survey. AB - OBJECTIVES: The number of depression symptoms can be considered as count data in order to get complete and accurate analyses findings in studies of depression. This study aims to compare the goodness of fit of four count outcomes models by a large survey sample to identify the optimum model for a risk factor study of the number of depression symptoms. METHODS: 15 820 subjects, aged 10 to 80 years old, who were not suffering from serious chronic diseases and had not run a high fever in the past 15 days, agreed to take part in this survey; 15 462 subjects completed all the survey scales. The number of depression symptoms was the sum of the 'positive' responses of seven depression questions. Four count outcomes models and a logistic model were constructed to identify the optimum model of the number of depression symptoms. RESULTS: The mean number of depression symptoms was 1.37+/-1.55. The over-dispersion test statistic O was 308.011. The alpha dispersion parameter was 0.475 (95% CI 0.443 to 0.508), which was significantly larger than 0. The Vuong test statistic Z was 6.782 and the P value was <0.001, which showed that there were too many zero counts to be accounted for with traditional negative binomial distribution. The zero-inflated negative binomial (ZINB) model had the largest log likelihood and smallest AIC and BIC, suggesting best goodness of fit. In addition, predictive probabilities for many counts in the ZINB model fitted the observed counts best. CONCLUSIONS: All fitting test statistics and the predictive probability curve produced the same findings that the ZINB model was the best model for fitting the number of depression symptoms, assessing both the presence or absence of depression and its severity. PMID- 29187410 TI - Protective effect of smoking against pterygium development in men: a nationwide longitudinal cohort study in South Korea. AB - OBJECTIVE: The present study aimed to evaluate the association between smoking and incident pterygium in adult Korean men. DESIGN: A retrospective nationwide longitudinal cohort. SETTING: National Health Insurance database of South Korea. PARTICIPANTS: This study included Korean men (age range: 40-79 years) registered in the Korea National Health Insurance Service database from 2002 through 2013. We compared HRs for pterygium between 90 547 current/past and 90 547 never smokers via 1:1 propensity-matched analysis. PRIMARY OUTCOME MEASURE: Incident cases of pterygium were identified from the database. RESULTS: Pterygium developed in 5389 (6.0%) never-smokers and 3898 (4.3%) past/current smokers (P<0.001). The incidence of pterygium per 1000 person-years in never-smokers and in past/current smokers was 6.5 and 4.7, respectively (age-adjusted HR, 0.73; 95% CI, 0.70 to 0.76). This protective effect was more pronounced among current smokers than among past smokers (for current smokers: HR, 0.68; 95% CI, 0.65 to 0.71 and for past smokers: HR, 0.85; 95% CI, 0.80 to 0.90). A longer duration of smoking and higher amounts of cigarette consumption were associated with a lower incidence of pterygium. CONCLUSIONS: Longitudinally, cigarette smoking was associated with a reduced risk of pterygium, and this protective effect was more pronounced among current smokers than among past smokers. PMID- 29187411 TI - Lived experience of women with gestational diabetes mellitus living in China: a qualitative interview study. AB - OBJECTIVE: To explore the lived experience of women with gestational diabetes mellitus (GDM) living in China in order to add knowledge about how the Chinese women suffer from GDM. DESIGN: A qualitative interpretive interview study. Data were collected with a snowball sampling technique. Phenomenological hermeneutics was used as the analysis method based on Ricoeur's phenomenological hermeneutical interpretation theory. SETTING: The study was performed at the participants' work places, or at the obstetric clinics or wards at two provincial hospitals and one municipal hospital in the southeast of China. PARTICIPANTS: Inclusion criteria were age >=18 years, diagnosis of GDM without other pregnancy complications, in 34th gestational weeks-postpartum 4th weeks and speaking Mandarin Chinese without speech impediment. 62 women, who met the inclusion criteria, took part in the study. RESULTS: The lived experience of the women with GDM living in China was formulated into a main theme: 'longing for caring care'. The main theme was derived from four themes: being stricken by GDM, wishing to receive caring GDM care, being left alone to struggle with GDM and trying to adjust and adapt to life with GDM. CONCLUSION: The eagerness for caring care in China was highlighted. The lack of caring care could be one of the possible reasons why the professional-patient relations were deteriorating in China. It could be useful for health providers and health policymakers to receive education and training about caring care. Using the health metaphor of balance and 'patient participation' and 'patient-centred' approaches may benefit women with GDM and thus improve the quality of care in China. PMID- 29187412 TI - Protocol for the melatools skin self-monitoring trial: a phase II randomised controlled trial of an intervention for primary care patients at higher risk of melanoma. AB - INTRODUCTION: Melanoma is the fifth most common cancer in the UK. Incidence rates have quadrupled over the last 30 years and continue to rise, especially among younger people. As routine screening of the general population is not currently recommended in the UK, a focus on secondary prevention through early detection and prompt treatment in individuals at increased risk of melanoma could make an important contribution to improve melanoma outcomes. This paper describes the protocol for a phase II, multisite, randomised controlled trial, in the primary care setting, for patients at increased risk of melanoma. A skin self-monitoring (SSM) smartphone 'App' was used to improve symptom appraisal and encourage help seeking in primary care, thereby promoting early presentation with skin changes suspicious of melanoma. METHODS AND ANALYSIS: We aim to recruit 200 participants from general practice waiting rooms in the East of England. Eligible patients are those identified at higher melanoma risk (using a real-time risk assessment tool), without a personal history of melanoma, aged 18 to 75 years. Participants will be invited to a primary care nurse consultation, and randomised to the intervention group (standard written advice on skin cancer detection and sun protection, loading of an SSM 'App' onto the participant's smartphone and instructions on use including self-monitoring reminders) or control group (standard written advice alone). The primary outcomes are consultation rates for changes to a pigmented skin lesion, and the patient interval (time from first noticing a skin change to consultation). Secondary outcomes include patient sun protection behaviours, psychosocial outcomes, and measures of trial feasibility and acceptability. ETHICS AND DISSEMINATION: NHS ethical approval has been obtained from Cambridgeshire and Hertfordshire research ethics committee (REC reference 16/EE/0248). The findings from the MelaTools SSM Trial will be disseminated widely through peer-reviewed publications and scientific conferences. TRIAL REGISTRATION NUMBER: ISCTRN16061621. PMID- 29187413 TI - Impact of inhalational versus intravenous anaesthesia on early delirium and long term survival in elderly patients after cancer surgery: study protocol of a multicentre, open-label, and randomised controlled trial. AB - INTRODUCTION: Elderly patients who have solid organ cancer often receive surgery. Some of them may develop delirium after surgery and delirium development is associated with worse outcomes. Furthermore, despite all of the advances in medical care, the long-term survival in cancer patients is far from optimal. Evidences suggest that choice of anaesthetics during surgery, that is, either inhalational or intravenous anaesthetics, may influence outcomes. However, the impact of general anaesthesia type on the occurrence of postoperative delirium is inconclusive. Although retrospective studies suggest that propofol-based intravenous anaesthesia was associated with longer survival after cancer surgery when compared with inhalational anaesthesia, prospective studies as such are still lacking. The purposes of this randomised controlled trial are to test the hypotheses that when compared with sevoflurane-based inhalational anaesthesia, propofol-based intravenous anaesthesia may reduce the incidence of early delirium and prolong long-term survival in elderly patients after major cancer surgery. METHODS AND ANALYSIS: This is a multicentre, open-label, randomised controlled trial with two parallel arms. 1200 elderly patients (>=65 years but <90 years) who are scheduled to undergo major cancer surgery (with predicted duration >=2 hours) are randomised to receive either sevoflurane-based inhalational anaesthesia or propofol-based intravenous anaesthesia. Other anaesthetics and supplemental drugs including sedatives, opioids and muscle relaxants are administered in both arms according to routine practice. The primary early outcome is the incidence of 7-day delirium after surgery and the primary long term outcome is the duration of 3-year survival after surgery. ETHICS AND DISSEMINATION: The study protocol has been approved by the Clinical Research Ethics Committees of Peking University First Hospital (2015[869]) and all participating centres. The results of early and long-term outcomes will be analysed and reported separately. TRIAL REGISTRATION NUMBER: ChiCTR-IPR-15006209; NCT02662257; NCT02660411. PMID- 29187414 TI - Postpartum management of hypertensive disorders of pregnancy: a systematic review. AB - OBJECTIVES: Hypertensive disorders of pregnancy (HDP) affect one in ten pregnancies and often persist postpartum when complications can occur. We aimed to determine the effectiveness and safety of pharmacological interventions, other interventions and different care models for postpartum hypertension management. DESIGN: A systematic review was undertaken. Nine electronic databases, including Medline, were searched from inception to 16 March 2017. After duplicate removal, 4561 records were screened. Two authors independently selected studies, extracted study characteristics and data, and assessed methodological quality. SETTING: Randomised controlled trials, case-control studies and cohort studies from any country and healthcare setting. PARTICIPANTS: Postnatal women with HDP. INTERVENTIONS: Therapeutic intervention for management of hypertension, compared with another intervention, placebo or no intervention. PRIMARY AND SECONDARY OUTCOME MEASURES: Outcome data were collected for maternal mortality and severe morbidity; systolic, diastolic and mean arterial blood pressure (BP) control; and safety data. Secondary outcome data collected included the length of postnatal hospital stay and laboratory values. RESULTS: 39 studies were included (n=2901). Results were heterogeneous in terms of intervention, comparison and outcome requiring a narrative approach. There were insufficient data to recommend any single pharmacological intervention. 18 studies reported calcium-channel blockers, vasodilators and beta-blockers lowered BP postpartum. 12 of these reported safety data. Limited data existed regarding management in the weeks following hospital discharge. Neither loop diuretics (three studies) nor corticosteroids (one study) produced clinical benefit. Uterine curettage significantly reduced BP over the first 48 hours postpartum (range 6-13 mm Hg) compared with standard care (eight studies), with safety data only reported by four of eight studies. CONCLUSION: There was insufficient evidence to recommend a particular BP threshold, agent or model of care, but three classes of antihypertensive appeared variably effective. Further comparative research, including robust safety data, is required. Curettage reduced BP, but without adequate reporting of harms, so it cannot currently be recommended. PMID- 29187415 TI - Is insomnia a risk factor for new-onset asthma? A population-based study in Taiwan. AB - OBJECTIVES: To determine whether insomnia at baseline is a risk factor for new onset asthma. METHODS: We recruited 48 871 patients with insomnia (insomnia group) newly diagnosed between 2002 and 2007, and 97 742 matched controls without insomnia (control group) from Taiwan's Longitudinal Health Insurance Database 2000. All of the patients were followed up for 4 years to see whether new-onset asthma developed. Patients with previous asthma or insomnia were excluded. The Poisson regression was used to estimate the incidence rate ratios (IRRs) and 95% CIs of asthma. Cox proportional hazard regression was used to calculate the risk of asthma between the two groups. RESULTS: After a 4-year follow-up, 424 patients in the insomnia group and 409 in the control group developed asthma. The incidence rate of asthma was significantly higher in the insomnia group (22.01vs10.57 per 10 000 person-years). Patients with insomnia have a higher risk of developing new-onset asthma during the 4-year follow-up (HR: 2.08, 95% CI 1.82 to 2.39). The difference remained significant after adjustment (adjusted HR: 1.89, 95% CI 1.64 to 2.17). CONCLUSIONS: This large population-based study suggests that insomnia at baseline is a risk factor for developing asthma. PMID- 29187416 TI - Improving hearing and vision in dementia: protocol for a field trial of a new intervention. AB - INTRODUCTION: Quality of life and other key outcomes may be improved by optimising hearing and vision function in people living with dementia. To date, there is limited research assessing the efficacy of interventions aimed at improving hearing and vision in people with dementia. Here, we outline a protocol to field test a newly developed home-based intervention, designed to optimise sensory functioning in people with dementia in three European sites. The results of this study will inform the design and conduct of a full-scale randomised controlled trial (RCT) in five European sites. METHODS AND ANALYSIS: In this multisite, single arm, open label, feasibility study, participants with dementia (n=24) will be assessed for hearing and vision impairments and be prescribed a hearing aid and/or glasses. Each participant will have a study partner ('dyads'). A subset of dyads will receive 'sensory support' from a 'sensory support therapist', comprising home visits over 12 weeks. The therapist will offer the following intervention: adherence support for corrective devices; adaptations to the home environment to facilitate sensory function; communication training; and referral to community-based support services. The primary outcomes will be process measures assessing the feasibility, tolerability and acceptability of: (1) the intervention components; (2) the method of implementation of the intervention and (3) the study procedures, including outcome assessment measures. Quantitative data will be collected at baseline and follow-up. Qualitative data using semistructured interviews will be collected postintervention and weekly, using participant diaries. Finally, we will explore a model of cost-effectiveness to apply in the subsequent full-scale trial. This feasibility study is a necessary step in the development of a complex, individualised, psychosocial intervention. The data gathered will allow logistical and theoretical processes to be refined in preparation for a full-scale RCT. ETHICS AND DISSEMINATION: Ethical approval was obtained in all three participating countries. Results of the field trial will be submitted for publication in a peer-reviewed journal. PMID- 29187417 TI - Use of humour in medical education: a survey of students and teachers at a medical school in China. AB - OBJECTIVE: Humour is a powerful resource in medical education. The purpose of this study is to investigate what students and teachers think about the use of humour. What challenges do teachers face in using humour and how they address them are also the subject of the present study. DESIGN: Separate cross-sectional questionnaire surveys. SETTING: Tongji Medical College and Tongji Hospital in China. PARTICIPANTS: 327 students at Tongji Medical College and 165 physician teachers at Tongji Hospital in China. MAIN OUTCOME MEASURES: The primary study outcome was assessed by proportion. RESULTS: 87% of student and teacher respondents agreed with using humour in the didactic setting. They felt humour fostered a positive didactic atmosphere. Interesting clinical case was the most frequently used humour type by teachers and considered the most effective by students. Lack of humorous materials related to the lecture subject was the main challenge to humour use cited by teachers. Collecting humorous materials in teacher's daily work and life, observing teachers with a reputation for successfully using humour, and efficiently using the internet-enhanced humour use ability. CONCLUSION: The present study confirms that most medical students and physician teachers support the use of humour in medical didactics, with particular strategies aiding its use and positive impact. PMID- 29187418 TI - A rapid review to identify physical activity accrued while playing golf. AB - OBJECTIVE: To identify physical activity (PA) accrued while playing golf and modifiers of PA accrued. DESIGN: A rapid review of primary research studies. Quality was assessed using the National Heart, Lung, and Blood Institute quality assessment tool for cohort and cross-sectional studies. METHODS AND OUTCOMES: The following databases were searched from 1900 to March 2017: SPORTDiscus, Web of Science, PsycINFO, MEDLINE, Google Scholar, Google Advanced Search, ProQuest, WHO International Clinical Trials Registry Platform. All primary research investigating golf or golfers with any of the following outcomes was included: metabolic equivalent of task, oxygen uptake, energy expenditure, heart rate, step count, distance covered, strength, flexibility, balance, sedentary behaviour. RESULTS: Phase one searching identified 4944 citations and phase two searching identified 170 citations. In total, 19 articles met inclusion criteria. Golf is primarily a moderate intensity PA, but may be low intensity depending on the playing population and various modifiers. Less PA is accrued by those who ride a golf cart compared with those walking the course. CONCLUSIONS: Golf can be encouraged in order to attain PA recommendations. Further research is required into the relationship between golf and strength and flexibility PA recommendations and how modifiers affect PA accrued. PROSPERO REGISTRATION NUMBER: CRD42017058237. PMID- 29187419 TI - Dissecting the Genetic Architecture of Shoot Growth in Carrot (Daucus carota L.) Using a Diallel Mating Design. AB - Crop establishment in carrot (Daucus carota L.) is limited by slow seedling growth and delayed canopy closure, resulting in high management costs for weed control. Varieties with improved growth habit (i.e., larger canopy and increased shoot biomass) may help mitigate weed control, but the underlying genetics of these traits in carrot is unknown. This project used a diallel mating design coupled with recent Bayesian analytical methods to determine the genetic basis of carrot shoot growth. Six diverse carrot inbred lines with variable shoot size were crossed in WI in 2014. F1 hybrids, reciprocal crosses, and parental selfs were grown in a randomized complete block design with two blocks in WI (2015) and CA (2015, 2016). Measurements included canopy height, canopy width, shoot biomass, and root biomass. General and specific combining abilities were estimated using Griffing's Model I, which is a common analysis for plant breeding experiments. In parallel, additive, inbred, cross-specific, and maternal effects were estimated from a Bayesian mixed model, which is robust to dealing with data imbalance and outliers. Both additive and nonadditive effects significantly influenced shoot traits, with nonadditive effects playing a larger role early in the growing season, when weed control is most critical. Results suggest the presence of heritable variation and thus potential for improvement of these phenotypes in carrot. In addition, results present evidence of heterosis for root biomass, which is a major component of carrot yield. PMID- 29187420 TI - Bayesian Diallel Analysis Reveals Mx1-Dependent and Mx1-Independent Effects on Response to Influenza A Virus in Mice. AB - Influenza A virus (IAV) is a respiratory pathogen that causes substantial morbidity and mortality during both seasonal and pandemic outbreaks. Infection outcomes in unexposed populations are affected by host genetics, but the host genetic architecture is not well understood. Here, we obtain a broad view of how heritable factors affect a mouse model of response to IAV infection using an 8 * 8 diallel of the eight inbred founder strains of the Collaborative Cross (CC). Expanding on a prior statistical framework for modeling treatment response in diallels, we explore how a range of heritable effects modify acute host response to IAV through 4 d postinfection. Heritable effects in aggregate explained ~57% of the variance in IAV-induced weight loss. Much of this was attributable to a pattern of additive effects that became more prominent through day 4 postinfection and was consistent with previous reports of antiinfluenza myxovirus resistance 1 (Mx1) polymorphisms segregating between these strains; these additive effects largely recapitulated haplotype effects observed at the Mx1 locus in a previous study of the incipient CC, and are also replicated here in a CC recombinant intercross population. Genetic dominance of protective Mx1 haplotypes was observed to differ by subspecies of origin: relative to the domesticus null Mx1 allele, musculus acts dominantly whereas castaneus acts additively. After controlling for Mx1, heritable effects, though less distinct, accounted for ~34% of the phenotypic variance. Implications for future mapping studies are discussed. PMID- 29187421 TI - Identifying Genetic Differences Between Dongxiang Blue-Shelled and White Leghorn Chickens Using Sequencing Data. AB - The Dongxiang Blue-shelled chicken is one of the most valuable Chinese indigenous poultry breeds. However, compared to the Italian native White Leghorn, although this Chinese breed possesses numerous favorable characteristics, it also exhibits lower growth performance and fertility. Here, we utilized genotyping sequencing data obtained via genome reduction on a sequencing platform to detect 100,114 single nucleotide polymorphisms and perform further biological analysis and functional annotation. We employed cross-population extended haplotype homozygosity, eigenvector decomposition combined with genome-wide association studies (EigenGWAS), and efficient mixed-model association expedited methods to detect areas of the genome that are potential selected regions (PSR) in both chicken breeds, and performed gene ontology (GO) enrichment and quantitative trait loci (QTL) analyses annotating using the Kyoto Encyclopedia of Genes and Genomes. The results of this study revealed a total of 2424 outlier loci (p-value <0.01), of which 2144 occur in the White Leghorn breed and 280 occur in the Dongxiang Blue-shelled chicken. These correspond to 327 and 94 PSRs containing 297 and 54 genes, respectively. The most significantly selected genes in Blue shelled chicken are TMEM141 and CLIC3, while the SLCO1B3 gene, related to eggshell color, was identified via EigenGWAS. We show that the White Leghorn genes JARID2, RBMS3, GPC3, TRIB2, ROBO1, SAMSN1, OSBP2, and IGFALS are involved in immunity, reproduction, and growth, and thus might represent footprints of the selection process. In contrast, we identified six significantly enriched pathways in the Dongxiang Blue-shelled chicken that are related to amino acid and lipid metabolism as well as signal transduction. Our results also reveal the presence of a GO term associated with cell metabolism that occurs mainly in the White Leghorn breed, while the most significant QTL regions mapped to the Chicken QTL Database (GG_4.0) for the Dongxiang Blue-shelled breed are predominantly related to lesions, bone mineral content, and other related traits compared to tibia length and body weight (i.e., at 14, 28, 42, and 70 d) in the White Leghorn. The results of this study highlight differences in growth, immunity, and egg quality traits between the two breeds, and provide a foundation for the exploration of their genetic mechanisms. PMID- 29187423 TI - The Effect of Telemedicine Follow-up Care on Diabetes-Related Foot Ulcers: A Cluster-Randomized Controlled Noninferiority Trial. AB - OBJECTIVE: To evaluate whether telemedicine (TM) follow-up of patients with diabetes-related foot ulcers (DFUs) in primary health care in collaboration with specialist health care was noninferior to standard outpatient care (SOC) for ulcer healing time. Further, we sought to evaluate whether the proportion of amputations, deaths, number of consultations per month, and patient satisfaction differed between the two groups. RESEARCH DESIGN AND METHODS: Patients with DFUs were recruited from three clinical sites in western Norway (2012-2016). The cluster-randomized controlled noninferiority trial included 182 adults (94/88 in the TM/SOC groups) in 42 municipalities/districts. The intervention group received TM follow-up care in the community; the control group received SOC. The primary end point was healing time. Secondary end points were amputation, death, number of consultations per month, and patient satisfaction. RESULTS: Using mixed effects regression analysis, we found that TM was noninferior to SOC regarding healing time (mean difference -0.43 months, 95% CI -1.50, 0.65). When competing risk from death and amputation were taken into account, there was no significant difference in healing time between the groups (subhazard ratio 1.16, 95% CI 0.85, 1.59). The TM group had a significantly lower proportion of amputations (mean difference -8.3%, 95% CI -16.3%, -0.5%), and there were no significant differences in the proportion of deaths, number of consultations, or patient satisfaction between groups, although the direction of the effect estimates for these clinical outcomes favored the TM group. CONCLUSIONS: The results suggest that use of TM technology can be a relevant alternative and supplement to usual care, at least for patients with more superficial ulcers. PMID- 29187422 TI - Dependency of Heterochromatin Domains on Replication Factors. AB - Chromatin structure regulates both genome expression and dynamics in eukaryotes, where large heterochromatic regions are epigenetically silenced through the methylation of histone H3K9, histone deacetylation, and the assembly of repressive complexes. Previous genetic screens with the fission yeast Schizosaccharomyces pombe have led to the identification of key enzymatic activities and structural constituents of heterochromatin. We report here on additional factors discovered by screening a library of deletion mutants for silencing defects at the edge of a heterochromatic domain bound by its natural boundary-the IR-R+ element-or by ectopic boundaries. We found that several components of the DNA replication progression complex (RPC), including Mrc1/Claspin, Mcl1/Ctf4, Swi1/Timeless, Swi3/Tipin, and the FACT subunit Pob3, are essential for robust heterochromatic silencing, as are the ubiquitin ligase components Pof3 and Def1, which have been implicated in the removal of stalled DNA and RNA polymerases from chromatin. Moreover, the search identified the cohesin release factor Wpl1 and the forkhead protein Fkh2, both likely to function through genome organization, the Ssz1 chaperone, the Fkbp39 proline cis trans isomerase, which acts on histone H3P30 and P38 in Saccharomyces cerevisiae, and the chromatin remodeler Fft3. In addition to their effects in the mating-type region, to varying extents, these factors take part in heterochromatic silencing in pericentromeric regions and telomeres, revealing for many a general effect in heterochromatin. This list of factors provides precious new clues with which to study the spatiotemporal organization and dynamics of heterochromatic regions in connection with DNA replication. PMID- 29187424 TI - Optimising Selenium for Modulation of Cancer Treatments. AB - Selenium is an essential trace element involved in many biological processes that are mediated through, at least, 25 selenoproteins expressed in humans. Extensive study of selenium compounds has demonstrated growth inhibition of malignant cells in a vast array of experimental models. Moreover combining selenium with conventional cancer therapy has yielded promising results in both preclinical studies and a cohort of human trials. The aim of this review is to highlight the current research evaluating the role of selenium compounds in combination with chemotherapy and radiation. Pharmacodymanic mechanisms responsible for the differential effects of the commonly studied compounds on healthy and malignant cells are presented and the pertinent in vitro and in vivo data summarised. The clinical utility of this approach is discussed both in terms of anti-tumour efficacy and toxicity prevention. Finally a case is made for novel trial designs to facilitate rapid progression into pivotal studies. PMID- 29187426 TI - 18F-Fdg-PET-guided Planning and Re-Planning (Adaptive) Radiotherapy in Head and Neck Cancer: Current State of Art. AB - BACKGROUND/AIM: A review of the literature is proposed as a contribution to current knowledge on technical, physical, and clinical issues about PET-guided planning and re-planning radiotherapy (RT) in head and neck cancer. MATERIALS AND METHODS: PubMed and Scopus electronic databases were searched for articles including clinical trials. Search terms were "gross tumor volume (GTV) delineation", "head and neck cancer", "radiotherapy", "adaptive radiotherapy" in combination with "PET". RESULTS: A 18F-FDG-PET and CT-scan comparison in GTV definition for RT planning of head and neck cancer was shown in twenty-seven clinical trials with a total of 712 patients. Only two clinical trials focused on PET-guided adaptive radiotherapy (ART) with a total of 31 patients. CONCLUSION: 18F-FDG-PET is able to achieve an accurate and precise definition of GTV boundaries during RT planning, especially in combination with CT-scan. ART strategies are proposed to evaluate tumor volume changes, plan boost irradiation on metabolically active residual neoplasm and protect organs at risk (OaRs). PMID- 29187425 TI - MiRNA-210: A Current Overview. AB - microRNAs (miRNAs) are a group of highly conserved small non-coding RNAs that were found to enhance mRNA degradation or inhibit post-transcriptional translation. Accumulating evidence indicates that miRNAs contribute to tumorigenesis and cancer metastasis. microRNA-210 has been largely studied in the past several years and has been identified as a major miRNA induced under hypoxia. A variety of miR-210 targets have been identified pointing to its role, not only in mitochondrial metabolism, but also in angiogenesis, the DNA damage response, cell proliferation, and apoptosis. Based on earlier research findings, this review aims to provide a current overview on the involvement of miRNA-210 in biological processes and diseases. PMID- 29187427 TI - The Role of the Androgen Receptor Signaling in Breast Malignancies. AB - Breast cancer (BrCa) is the most common malignancy among women worldwide, and one of the leading causes of cancer-related deaths in females. Despite the development of novel therapeutic modalities, triple-negative breast cancer (TNBC) remains an incurable disease. Androgen receptor (AR) is widely expressed in BrCa and its role in the disease may differ depending on the molecular subtype and the stage. Interestingly, AR has been suggested as a potential target candidate in TNBC, while sex hormone levels may regulate the role of AR in BrCa subtypes. In the presence of estrogen receptor alpha (ERa), AR may antagonize the ERalpha induced effects, whereas in the absence of estrogens, AR may act as an ERalpha mimic, promoting tumor. Thus, depending on the BrCa micro-environment, both agonists and antagonists of the AR have been suggested as therapeutic approaches. Herein, we review the role of AR signaling in BrCa and the molecular cross-talk mechanisms with other molecules/pathways, as well as its therapeutic implications in the different subtypes of the disease. PMID- 29187428 TI - Clinical, Histopathological and Cytogenetic Prognosticators in Uveal Melanoma - A Comprehensive Review. AB - Uveal melanoma is the most prevalent primary intraocular cancer in adults. Although it accounts for only 5% of all melanomas, it is responsible for 13% of deaths due to this type of cancer. A wide variety of therapeutic options of primary tumor is available and progress in its management is noticeable. The fact still remains, however, that almost half of patients develop metastases which may be due to practically undetectable cancer spread present as early as at diagnosis of the primary focus. Metastatic disease is uniformly fatal despite systemic therapy. Prediction of metastasis is crucial for prognosis. It also allows targeting of emerging new therapeutic methods to the appropriate group of patients. The Authors reviewed literature concerning epidemiology and etiopathogenesis of uveal melanoma, and its clinical, histopathological and cytogenetic prognosticators. PMID- 29187429 TI - Risk Factors for Cytomegalovirus Infection After Allogeneic Hematopoietic Cell Transplantation in Malignancies: Proposal for Classification. AB - AIM: To identify and classify risk factors for cytomegalovirus (CMV) infection and disease in patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT), treated mainly for acute leukemia. MATERIALS AND METHODS: A literature search was performed;eligible trials were clinical studies assessing the risk factors for CMV infection or disease in multivariate analysis. RESULTS: Early reactivation in the setting of allo-HSCT took place mainly in patients without CMV prophylaxis, while late reactivation mainly in those patients who had completed previous prophylaxis or were on anti-CMV strategy based on pre-emptive prophylaxis. We propose classifying risk factors for CMV reactivation and CMV disease in patients after allo-HSCT as major and minor ones. Three major risk factors for CMV reactivation and CMV disease were found: (i) CMV negative donor CMV-positive recipient serostatus, (ii) acute or chronic graft versus-host disease, and (iii) unrelated or mismatched donor. CONCLUSION: CMV reactivation should be regarded as a continuous function of recipient and donor CMV-seropositivity and recipient immune suppression, caused by conditioning, immunosuppressive therapy and human leukocyte antigen disparity between donor and recipient. PMID- 29187430 TI - The "Yin and Yang" of Platelet-rich Plasma in Breast Reconstruction After Mastectomy or Lumpectomy for Breast Cancer. AB - Surgery remains the mainstay of treatment for breast cancer, including complete or partial mastectomy and lumpectomy. Breast reconstruction has gained popularity mainly due to its tremendous impact on the psychological status of the patients. Autologous fat grafting is a well-established method used in cosmetic surgery; however, fat re-absoprtion, fat necrosis, calcifications and oil-cyst formation are some usually encountered complications limiting the efficacy of this approach. Platelet-rich plasma (PRP) has recently been postulated as a promising method for tissue regeneration since it contains high levels of diverse human growth factors. To date, preliminary results from clinical studies regarding the combination of PRP and fat grafting in breast reconstruction have shown ambiguous results, whereas preclinical studies are more favorable. However, concerns have been raised regarding the extent of cellular promotion induced by PRP application and the corresponding potential malignant transformation. The aim of our study was to present, analyze and critically evaluate the role of PRP in breast reconstruction after breast cancer surgery in terms of efficacy and oncological safety highlighting the caution that needs to be taken in order to eliminate any chance of recurrence in patients who have theoretically undergone complete excision of the tumor burden. PMID- 29187431 TI - Microsatellite Instability as a Prognostic Factor in Stage II Colon Cancer Patients, a Meta-Analysis of Published Literature. AB - BACKGROUND/AIM: The prognostic role of microsatellite instability (MSI) in stage II colon cancer patients remains controversial despite the fact that it has been investigated in a number of studies. Hazard ratios differ considerably among these studies. We performed a meta-analysis to define the significance of MSI in this group of patients. MATERIALS AND METHODS: Studies indexed in PubMed presenting separate data on MSI status and survival outcomes for stage II colon cancer patients have been analyzed using fixed-effect meta-analysis of hazard ratio (HR) according to the method of Peto. RESULTS: Analysis was performed on 19 studies including 5,998 patients. A 47.3% of patients received postoperative chemotherapy and included 52.8% males and 47.2% females. Eight studies included some rectal cancer patients although this cohort was not clearly defined in 3 of these. MSI observed in 20.8% (mean) of patients (median 19.9%). HR for overall survival (OS) of MSI vs. microsatellite stable (MSS) tumors for the entire population: 0.73 (95% confidence interval (CI)=0.33-1.65); HR for disease-free survival (DFS):0.60 (95%CI=0.27-1.32). No statistical significant difference was found when studies analyzing MSI with genotyping (MG) and immunohistochemistry (IHC) were compared separately (MG vs. IHC: HR OS 0.45, 95%CI=0.10-2.05 vs. 0.95, 95%CI=0.57-1.58; HR DFS 0.51, 95%CI=0.14-1.85 vs. 0.67, 95%CI=0.26-1.70). However, numerically MSI determination with genotyping shows significantly lower hazard ratios for both DFS and OS. Separate analysis of studies describing colon cancer patients only showed HR OS 0.72 (95%CI=0.31-1.71); HR DFS 0.60 (95%CI=0.27 1.31). CONCLUSION: No significant relation was found between MSI status and OS or DFS. Routine determination of MSI status to guide postoperative management of stage II colon cancer patients cannot be recommended. New large scale high quality studies are needed to answer this question definitively, since currently analyzed studies vary considerably. PMID- 29187432 TI - Paclitaxel, Carboplatin and 1,25-D3 Inhibit Proliferation of Endometrial Cancer Cells In Vitro. AB - BACKGROUND/AIM: Endometrial cancer cells are known to be sensitive to carboplatin and paclitaxel. Furthermore, vitamin D (1,25-D3) has been reported to inhibit endometrial cancer cell growth both as a single agent and combined with carboplatin. However, there are no studies comparing the effect of paclitaxel and carboplatin as single agents vs. in combination in endometrial cancer cell lines. Neither has the effect of 1,25-D3 been studied with paclitaxel. The present study investigated the effect of paclitaxel, carboplatin and 1,25-D3 on the growth of endometrial cancer cells in vitro. MATERIALS AND METHODS: Two endometrial adenocarcinoma cell lines (UT-EC-1 and UT-EC-3) were cultured with different doses of paclitaxel, carboplatin and 1,25-D3. The cellular VDR (vitamin D receptor) mRNA levels were measured and the expression of estrogen (ER) and progesterone (PR) receptors by the cells was determined. RESULTS: In the UT-EC-1 cell line the growth inhibition was 72% with paclitaxel, 54% with carboplatin and 73% with the combination of these compounds. The corresponding numbers in UT-EC-3 were 70%, 33% and 65%, respectively. 1,25-D3 suppressed cell growth 88% with paclitaxel, 63% with carboplatin and 87% with their combination in the UT-EC-1 cell line. CONCLUSION: In both cell lines, single-agent paclitaxel was as effective as the combination of the compounds and more effective than single carboplatin. 1,25-D3 may further contribute to the cytotoxic effect of these agents. PMID- 29187433 TI - ESE-1 Knockdown Attenuates Growth in Trastuzumab-resistant HER2+ Breast Cancer Cells. AB - BACKGROUND/AIM: ESE-1/Elf3 controls transformation properties in mammary epithelial cells, and is most clinically relevant in HER2+ breast cancer. Herein we showed that ESE-1 knockdown inhibits tumorigenic growth in HER2+, trastuzumab resistant HR20 (derived from HER2+ ER+ BT474) and Pool2 (derived from HER2+ ER- SKBR3 cells) cell lines. MATERIALS AND METHODS: We used cell proliferation, clonogenicity, viability, and soft agar assays to measure the effects of ESE-1 knockdown in cell lines. RESULTS: ESE-1 knockdown in the resistant cell lines inhibited HER2 and other downstream effectors in a cell-type specific manner, but caused down-regulation of pAkt and cyclin D1 in both sublines. In parental BT474 and SKBR3 ESE-1 silencing revealed a potent anti-proliferative effect that mimics the trastuzumab-mediated growth inhibition but did not enhance trastuzumab sensitivity in the resistant sublines. CONCLUSION: This study provides rationale to study ESE-1 as a novel mean to treat HER2+ patients who show resistance to anti-HER2 therapy. PMID- 29187434 TI - Sensitization of rhTRAIL-resistant Triple-negative Breast Carcinoma Through Silibinin Co-Treatment. AB - BACKGROUND/AIM: Triple-negative breast cancer (TNBC) is the most fatal form of breast cancer due to the shortcomings of therapies. However, recombinant human tumor necrosis factor-related apoptosis-inducing ligand (rhTRAIL) is a promising anticancer therapeutic that possesses the capability to promote the induction of apoptosis in cancer cells, but some TNBCs are resistant to rhTRAIL's pro apoptotic effects. Therefore, a combinatorial treatment approach with silibinin and rhTRAIL was considered in order to sensitize rhTRAIL-resistant TNBCs. MATERIALS AND METHODS: The co-treatment of rhTRAIL and silibinin's impact on apoptosis induction in rhTRAIL-resistant TNBC BT-20 and HCC1937 cells was inspected via application of Annexin V/PI assays and western blot analysis. RESULTS: Silibinin possessed the ability to sensitize the examined rhTRAIL resistant TNBC cells to rhTRAIL-induced apoptosis through the up-regulation of death receptors 4 and 5 and the down-regulation of survivin transcriptionally. CONCLUSION: Silibinin is a good sensitizing agent for rhTRAIL-resistant TNBCs. PMID- 29187435 TI - Evaluating Metformin as a Potential Chemosensitizing Agent when Combined with Docetaxel Chemotherapy in Castration-resistant Prostate Cancer Cells. AB - BACKGROUND/AIM: Docetaxel, the first-line chemotherapy for metastatic castration resistant prostate cancer (mCRPC), provides certain survival benefits, but is associated with significant toxicity. A novel therapeutic approach for mCRPC is combining docetaxel with a chemosensitizing agent. We hypothesized that metformin, a potential chemosensitizer, would improve docetaxel efficacy in CRPC cells. MATERIALS AND METHODS: MTS assays were used to determine the effect of metformin-docetaxel treatment on PC3 and DU145 cell viability. Wound-healing and ATP concentration assays were used to evaluate cell migration and intracellular ATP levels following metformin-docetaxel treatment. Western blotting was used for mechanistic evaluation. RESULTS: Metformin-docetaxel treatment significantly reduced PC3 cell viability. Metformin-docetaxel treatment did not significantly affect cell migration or intracellular ATP levels. Western blotting revealed metformin-docetaxel treatment did not significantly change AMPK or P-AMPK expression patterns. CONCLUSION: Metformin may be an effective chemosensitizer for certain types of CRPC cells, but further investigation is needed. PMID- 29187436 TI - Identification of CpG Sites of SERPINA5 Promoter with Opposite Methylation Patterns in Benign and Malignant Prostate Cells. AB - BACKGROUND/AIM: To date there has been no investigation into the epigenetic regulation of the serine protease inhibitor SERPINA5 in prostate cancer, where lack of this gene was considered to facilitate invasive growth patterns. MATERIALS AND METHODS: Methylation degrees of eight CpG sites of SERPINA5 were analyzed in normal and malignant prostate cells using nucleotide sequencing, methylation-specific high resolution melting and digital droplet PCR techniques. RESULTS: The methylation degree of five CpG sites significantly correlated with lower SERPINA5 expression levels. In contrast, two CpG sites (at -19 bp and -14 bp from the transcription start site) were hypermethylated in normal epithelial prostate cells, benign hyperplasic cells and low-invasive malignant LNCaP cells, whereas in aggressive DU-145 and PC-3 cell lines, these sites were essentially unmethylated. CONCLUSION: Novel methylation patterns of two distinct CpG sites of the SERPINA5 promoter may be useful for differentiating benign from malignant prostate disease. PMID- 29187437 TI - Antiproliferative Activity and Induction of Apoptosis in Human Melanoma Cells by Houttuynia cordata Thunb Extract. AB - BACKGROUND/AIM: To analyze the apoptotic effect of Houttuynia cordata Thunb (HCT) extract on human melanoma A375 cells and its underlying mechanisms. MATERIALS AND METHODS: The effects of HCT on cell death were determined using the MTT assay. Hoechst 33342 staining was conducted to confirm the detection of cell apoptosis. Caspase-3 and caspase-8 mRNA and cleaved protein levels were investigated by RT PCR and western blotting, respectively. The release of high mobility group box 1 (HMGB1) and phosphorylation of mitogen-activated protein kinase (MAPK) were determined by ELISA. RESULTS: Caspase-3 and caspase-8 specific inhibitors suppressed HCT-induced cell death. HCT increased caspase-3 and caspase-8 mRNA, protein levels, and caspase activities in a concentration- and time-dependent manner. HCT induced MAPK phosphorylation in a time-dependent fashion. Pretreatment of cells with a selective inhibitor of p38 MAPK reduced apoptosis and reversed the levels of HMGB1 release in response to HCT treatment. CONCLUSION: HCT induces A375 programmed cell death by activating the caspase dependent pathway and by p38 phosphorylation associated with HMGB1 reduction. PMID- 29187438 TI - Functional Characterization of VEGF- and FGF-induced Tumor Blood Vessel Models in Human Cancer Xenografts. AB - BACKGROUND/AIM: Tumor angiogenesis induced by vascular endothelial growth factor (VEGF) and/or fibroblast growth factor (FGF) plays an important role in tumor growth, metastasis, and drug resistance. However, the characteristics of tumor vessels derived from these angiogenic factors have not been fully explored. MATERIALS AND METHODS: To functionally examine tumor vessels, we developed in vivo VEGF- and FGF-induced tumor blood vessel models. We performed immunohistochemistry and Hoechst perfusion assay to elucidate histopathological differences between the derived tumor vessels. To kinetically understand tumor perfusion, we employed radiolabeled PEGylated liposomes. RESULTS: While tumor vessel density was substantially increased by enhanced expression levels of VEGF and FGF, permeability of VEGF-driven tumor vessels was significantly higher than that of FGF-driven ones, the latter demonstrating an increased number of pericyte covered vessels. Accordingly, we observed an increased tumor retention of the PEGylated liposomes in the VEGF-driven tumor. CONCLUSION: Our in vivo models of tumor vessel demonstrate the frequency of pericyte coverage and tumor perfusion levels as major functional differences between VEGF- and FGF-driven tumor vessels. PMID- 29187439 TI - Expression of FAS-L Differs from Primary to Relapsed Low-grade Gliomas and Predicts Progression-free Survival. AB - BACKGROUND/AIM: The tumor necrosis factor FAS is overexpressed in high-grade gliomas (HGG). Only little is known about FAS or FAS ligand (FAS-L) in low-grade gliomas (LGG). We explored FAS/FAS-L expression in LGG, focusing on differences in primary and relapsed LGG and on its prognostic value. PATIENTS AND METHODS: A total of 133 glioma samples (73 LGG, 60 HGG) were collected. The LGG samples included 15 matched pairs of primary and relapsed tumors. RT-PCR was performed to measure FAS/FAS-L expression, using subunit A, flavoprotein variant (SDHA) as housekeeper. Clinical data included progression free- (PFS) and overall survival (OS). RESULTS: LGG showed significantly lower FAS but higher FAS-L expression than HGG. The FAS-L expression was higher in primary compared to relapsed LGG and had a positive prognostic value concerning PFS (median 45.20 vs. 31.37 months). CONCLUSION: FAS-L could act as a prognostic marker and potential target in primary LGG. PMID- 29187440 TI - Liprin-alpha4 as a Possible New Therapeutic Target for Pancreatic Cancer. AB - BACKGROUND/AIM: In pancreatic cancer, where the microenvironment is extremely hypoxic, analyzing signal transduction under hypoxia is thought to be significantly important. By investigating microarray analysis of pancreatic cancer cells cultured under both normoxia and hypoxia, we found that the expression of leukocyte common antigen-related (LAR)-interacting protein (liprin) alpha4 was extremely increased under hypoxia compared to under normoxia. MATERIALS AND METHODS: In the present study, the biological significance of liprin-alpha4 in pancreatic cancer was investigated and whether liprin-alpha4 has potential as a therapeutic target for pancreatic cancer was estimated. RESULTS: Suppression of liprin-alpha4 reduced proliferation of pancreatic cancer cells both in vitro and in vivo. Inhibition of liprin-alpha4 also reduced invasiveness through the suppression of endothelial-mesenchymal transition. Stimulation by liprin-alpha4 was through phosphoinositide 3-kinase and mitogen-activated protein kinase signaling pathways. CONCLUSION: Liprin-alpha4 plays a pivotal role in inducing malignant phenotypes such as increased proliferation and invasion in pancreatic cancer, and that liprin-alpha4 could be a new effective therapeutic target for pancreatic cancer. PMID- 29187441 TI - Flavopiridol Strongly Sensitizes Canine Lymphoma Cells to TRAIL-induced Apoptosis. AB - BACKGROUND/AIM: Targeting the extrinsic apoptotic pathway is an interesting option for anticancer therapy. A protein which such ability is Apo2 ligand, also known as TNF-related apoptosis-inducing ligand (TRAIL). The aim of this study was to examine the possibility of sensitizing resistant CLBL-1 canine lymphoma cells to TRAIL-induced apoptosis by using flavopiridol (FVP) a cyclin-dependent kinase inhibitor (CDKs). MATERIALS AND METHODS: The CLBL-1 (canine B-cell lymphoma cell line) was used in the study. The effect of FVP and TRAIL treatment on apoptosis induction was assessed by flow cytometry and western blot. RESULTS: Although canine lymphoma cells were resistant to TRAIL-induced apoptosis, combination of this death ligand with FVP was able to overcome TRAIL resistance of CLBL-1 lymphoma cells. CONCLUSION: Our results demonstrated that although canine lymphoma cells were resistant to TRAIL-induced apoptosis, combination of this death ligand with FVP was able to overcome TRAIL resistance of CLBL-1 lymphoma cell line. Although further investigation is required to deepen the knowledge of TRAIL as an antitumor agent in canine cancers, our results open the door to future use of TRAIL-based treatment strategies in veterinary oncology. PMID- 29187442 TI - Updated Histologic Classification of Adenomas and Carcinomas in the Colon of Carcinogen-treated Sprague-Dawley Rats. AB - BACKGROUND: Recent studies have disclosed novel histological phenotypes of colon tumours in carcinogen-treated rats. The aim of this study was to update the current histological classification of colonic neoplasias in Sprague-Dawley (SD) rats. MATERIALS AND METHODS: Archival sections from 398 SD rats having 408 neoplasias in previous experiments were re-evaluated. RESULTS: Of the 408 colonic neoplasias, 11% (44/408) were adenomas without invasive growth and 89% (364/408) invasive carcinomas. Out of the 44 adenomas, 82% were conventional (tubular or villous), 14% traditional serrated (TSA; with unlocked serrations or with closed microtubules) and 5% gut-associated lymphoid tissue (GALT)-associated adenomas. Out of 364 carcinomas, 57% were conventional carcinomas, 26% GALT carcinomas, 8% undifferentiated, 6% signet-ring cell carcinomas, and 4% traditional serrated carcinomas (TSC). Thus, conventional adenomas, conventional carcinomas and GALT associated carcinomas predominated (p<0.05). CONCLUSION: The updated classification of colonic tumours in SD rats includes conventional adenomas, TSA, GALT-associated adenomas, conventional carcinomas, TSC, GALT-associated carcinomas, signet-ring cell carcinomas and undifferentiated carcinomas. Several of the histological phenotypes reported here are not included in any of the current classifications of colonic tumours in rodents. This updated classification fulfils the requirements for an animal model of human disease, inasmuch as similar histological phenotypes of colon neoplasias have been documented in humans. PMID- 29187443 TI - Total Knockdown of LMW-PTP in MDA-MB-231 Cells Reduces Osteoclastogenesis. AB - BACKGROUND: Low molecular weight protein tyrosine phosphatase (LMW-PTP) has been related to tumorigenesis, having both oncogenic and anti-oncogenic roles. The differential roles of its main active isoforms (fast and slow) may account for these discrepancies. The fast isoform has been described to be involved in the bone-metastatic process, although knockdown of the slow isoform was recently reported to reduce osteoclastogenesis. We aimed to study the influence of LMW-PTP isoforms on osteoclast differentiation. MATERIALS AND METHODS: Osteoclast precursors (RAW 264.7) were cultured with conditioned medium from MDA-MB-231 breast cancer cells with total knockdown of LMW-PTP and with knockdown of the slow isoform of LMW-PTP. Tartarate-resistant acid phosphatase (TRAP) staining and quantification were performed to assess osteoclast differentiation. RESULTS: Total knockdown of LMW-PTP, but not of slow LMW-PTP significantly reduced osteoclast differentiation of RAW 264.7 cells. CONCLUSION: We suggest that total LMW-PTP increases osteoclastic differentiation, albeit not at the expense of the slow isoform. PMID- 29187444 TI - Contribution of Matrix Metalloproteinase-7 Genotypes to the Risk of Non-solid Tumor, Childhood Leukemia. AB - BACKGROUND/AIM: The matrix metalloproteinases (MMPs) are important in inflammation and carcinogenesis, and the genotypic role of MMP7 has never been examined in leukemia to date. Therefore, in this study we aimed to evaluate the contribution of the genotypic variants in the promoter region of MMP7 (A-181G and C-153T) to childhood acute lymphoblastic leukemia (ALL) risk in Taiwan. MATERIALS AND METHODS: In this case-control study, 266 patients with childhood ALL and 266 non-cancer controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS: The distribution of AA, AG and GG for MMP7 promoter A-181G genotype was 83.5, 12.0 and 4.5% in the childhood ALL group and 89.8%, 9.4 and 0.8% in the non-cancer control group, respectively (p for trend=0.0134), significantly differentially distributed between childhood ALL and control groups. The comparisons in allelic frequency distribution also support the findings that G appears to be the risky allele in childhood ALL. In genotype and gender interaction analysis, it was found that boys carrying the MMP7 A-181G GG and AG+GG genotypes had 9.05- and 2.45-fold odds ratios (ORs) (p=0.0135 and 0.0142, respectively) for childhood ALL compared to those carrying wild-type AA genotype. But these differences were not found in girls. Analysis of genotype interaction with age of onset age showed those aged less than 3.5 years at onset carrying the GG or AG+GG genotypes also had elevated ORs of 8.79- and 2.04-fold (p=0.0150 and 0.0413, respectively) for childhood ALL, but there was no such difference for those having an age at onset of 3.5 years or more. CONCLUSION: Our results indicate that the MMP7 A-181G genotype interacts with age and gender and may serve as an early and predictive biomarker for childhood ALL. PMID- 29187445 TI - The Contrasting Role of the Mediator Subunit MED30 in the Progression of Bladder Cancer. AB - BACKGROUND/AIM: The Mediator complex is a key regulator of gene transcription, and several studies have demonstrated altered expression of particular subunits in diverse human diseases, especially cancer. To date, nothing is known about the role of MED30 in bladder cancer. MATERIALS AND METHODS: We, therefore, performed an RNA expression and survival analysis of the subunit MED30 in 537 samples of bladder cancer by using the database cBioPortal. To validate these data on the protein level, we practiced immunohistochemical staining against MED30 on a tissue microarray containing 210 samples of all tumour stages and performed survival analyses. For functional analysis, the siRNA-mediated knockdown of MED30 was performed in the cell lines T24 and TCCSUP followed by proliferation, migration, and invasion assays. RESULTS: On the mRNA and protein levels, higher expression of MED30 is associated with better patient survival. In accordance with this, advanced T- and N-stages showed lower expression of MED30. In contrast, knockdown of MED30 led to reduction of the tumour parameters proliferation, migration, and invasion in the BCa cell lines. CONCLUSION: MED30 appears to be integrated in the progression of the urothelial tumour in the bladder. PMID- 29187446 TI - TP53 Mutation Status of Tubo-ovarian and Peritoneal High-grade Serous Carcinoma with a Wild-type p53 Immunostaining Pattern. AB - BACKGROUND/AIM: Diffuse and strong nuclear p53 immunoreactivity and a complete lack of p53 expression are regarded as indicative of missense and nonsense mutations, respectively, of the TP53 gene. Tubo-ovarian and peritoneal high-grade serous carcinoma (HGSC) is characterized by aberrant p53 expression induced by a TP53 mutation. However, our experience with some HGSC cases with a wild-type p53 immunostaining pattern led us to comprehensively review previous cases and investigate the TP53 mutational status of the exceptional cases. MATERIALS AND METHODS: We analyzed the immunophenotype of 153 cases of HGSC and performed TP53 gene sequencing analysis in those with a wild-type p53 immunostaining pattern. RESULTS: Immunostaining revealed that 109 (71.3%) cases displayed diffuse and strong p53 expression (missense mutation pattern), while 39 (25.5%) had no p53 expression (nonsense mutation pattern). The remaining five cases of HGSC showed a wild-type p53 immunostaining pattern. Direct sequencing analysis revealed that three of these cases harbored nonsense TP53 mutations and two had novel splice site deletions. CONCLUSION: TP53 mutation is almost invariably present in HGSC, and p53 immunostaining can be used as a surrogate marker of TP53 mutation. In cases with a wild-type p53 immunostaining pattern, direct sequencing for TP53 mutational status can be helpful to confirm the presence of a TP53 mutation. PMID- 29187447 TI - Analysis of Autoantibodies Related to Tumor Progression in Sera from Patients with High-grade Non-muscle-invasive Bladder Cancer. AB - BACKGROUND/AIM: Bladder cancer (BC) has a high recurrence rate and may progress to being a muscle-invasive lesion, that is potentially associated with a poor prognosis. We identified tumor-associated proteins that were recognized by autoantibodies in sera from patients with high-grade non-muscle-invasive bladder cancer (HG-NMIBC) by proteomic analysis. MATERIALS AND METHODS: The serum levels of these autoantibodies against identified proteins were validated by dot blot analysis with sera from 95 patients with BC and 35 healthy controls. The expression of identified proteins was immunohistochemically analyzed in 115 BC tissues. RESULTS: Autoantibody against protein phosphatase 1, catalytic subunit, alpha isoform (PPP1CA) protein was detected in pretreated sera from patients with HG-NMIBC who showed progression. The serum IgG level of anti-PPP1CA autoantibody was significantly correlated with pathological stage, grade, lymphovascular invasion, and prognosis. The immunoreactions for PPP1CA protein in BC was significantly correlated with pathological stage, grade, and lymphovascular invasion. CONCLUSION: PPP1CA is a candidate sero-diagnostic and prognostic marker for patients with BC. PMID- 29187448 TI - Potential Roles of GLUT12 for Glucose Sensing and Cellular Migration in MCF-7 Human Breast Cancer Cells Under High Glucose Conditions. AB - BACKGROUND/AIM: Recent reports have indicated that hyperglycaemia is associated with breast cancer progression. High glucose conditions corresponding to hyperglycaemia significantly promote migration of MCF-7 human breast cancer cells, however, little is known about the mechanisms of glucose sensing for the acquisition of migratory properties by MCF-7 cells. This study investigated glucose sensing and mediation, which are responsible for the high motility of MCF 7 cells. MATERIALS AND METHODS: We evaluated the migration of MCF-7 cells cultured in high glucose-containing medium and essential regulatory factors from the perspective of the glucose transport system. RESULTS: We demonstrated that glucose transporter 12 (GLUT12) protein level increased in MCF-7 cells and co localized with actin organization under high glucose conditions. Moreover, GLUT12 knockdown completely abrogated high glucose-induced migration, indicating that GLUT12 functionally participates in sensing high glucose concentrations. CONCLUSION: GLUT12 plays a critical role in the model of breast cancer progression through high glucose concentrations. PMID- 29187449 TI - High STAT4 Expression Indicates Better Disease-free Survival in Patients with Gastric Cancer. AB - BACKGROUND: The aim of this study was to investigate the significance of signal transducer and activator of transcription 4 (STAT4) expression and the correlation between STAT4 and interferon gamma (IFN-gamma) in patients with gastric cancer. PATIENTS AND METHODS: Sixty-two patients who underwent gastrectomy for gastric cancer were enrolled in the study. STAT4 and IFNG mRNA expression was evaluated by quantitative real-time polymerase chain reaction (PCR). Immunohistochemistry was performed to examine CD8+ T-cells, and STAT4 and IFN-gamma expression. RESULTS: STAT4 mRNA expression was significantly correlated with IFNG mRNA expression (p<0.05). Regarding disease-free survival, there was a significant difference between the groups with high and low STAT4 expression (5 year disease-free survival: 77.8% and 56.4%, p<0.05). Univariate analysis revealed that tumor differentiation and STAT4 expression were significant factors for tumor recurrence. CONCLUSION: High expression of STAT4 in gastric cancer predicted a better clinical outcome. STAT4 might be a useful biomarker to identify patients at high risk of recurrence after gastrectomy. PMID- 29187450 TI - Oral Squamous Cell Carcinoma-derived Sonic Hedgehog Promotes Angiogenesis. AB - BACKGROUND: Sonic hedgehog (SHH) signaling is related to the pathogenesis of oral squamous cell carcinoma (OSCC), but its role in OSCC is not yet well understood. In this study, we analyzed the role of SHH signaling in OSCC. MATERIALS AND METHODS: We examined the expression pattern of SHH and its signal proteins in clinically resected OSCC samples by immunohistochemistry. We also evaluated the function of SHH signaling using the hedgehog signaling inhibitor cyclopamine in vivo and in vitro by proliferation, migration and angiogenesis analyses. RESULTS: We found that SHH was highly expressed in human tongue OSCC, whereas patched (PTCH1), glioma-associated oncogene 1 (GLI1) and GLI2 proteins were expressed in the microvascular cells in the tumor invasive front. Administration of cyclopamine to mice suppressed the growth and angiogenesis of OSCC xenografts in vivo. Moreover, cyclopamine inhibited endothelial cell proliferation and migration, and reduced aorta vascular length in the rat. CONCLUSION: These findings suggest that OSCC-derived SHH stimulates angiogenesis at the tumor invasive front. PMID- 29187451 TI - Cold Atmospheric Plasma (CAP) and CAP-Stimulated Cell Culture Media Suppress Ovarian Cancer Cell Growth - A Putative Treatment Option in Ovarian Cancer Therapy. AB - BACKGROUND/AIM: Ovarian cancer (OC) is a gynecologic tumor with poor prognosis. Despite radical cytoreductive surgery and platinum-based adjuvant systemic treatment, OC will relapse in the majority of the cases. Thus, cold atmospheric plasma (CAP), a highly reactive physical state bearing diverse biological activities being suited for anticancer therapy, may be a promising option in OC therapy. MATERIALS AND METHODS: OC cell lines were exposed either directly to the CAP or to cell culture medium previously exposed to CAP. Cell proliferation and cell motility was measured. RESULTS: The data demonstrated, that even a single application of a short-term CAP treatment led to an attenuation of OC cell growth and motility. Moreover, incubation with CAP-treated cell culture medium gave similar effects. Results were consistent in four OC cell lines. CONCLUSION: In summary, the CAP application in oncological surgery leads to strong anti proliferative effects and opens up novel opportunities for the OC treatment. PMID- 29187452 TI - Y-box Binding Protein-1 Enhances Oncogenic Transforming Growth Factor beta Signaling in Breast Cancer Cells via Triggering Phospho-Activation of Smad2. AB - BACKGROUND/AIM: Transforming growth factor beta (TGFbeta) plays a role in diverse oncogenic pathways including cell proliferation and cell motility and is regulated by the pleiotropic factor Y-box binding protein-1 (YB-1). In breast cancer, Sma/Mad related protein 2 (Smad2) represents the most common downstream transducer in TGFbeta signaling. MATERIALS AND METHODS: Here, YB-1's impact on Smad2 phospho-activation was characterized by incubation of the breast cancer cell line MCF-7 with or without TGFbeta1 in the absence or presence of overexpressed YB-1 protein. The phospho-status of Smad2 was assessed via western blotting. RESULTS: Analysis of MCF-7 cells revealed no induction of total Smad2 neither in the presence of TGFbeta1, nor during YB-1 overexpression. In contrast, incubation with TGFbeta1 led to an increase of phosphorylated Smad2 forms which was significantly amplified by simultaneously overexpressed YB-1 (2.8+/-0.2 fold). CONCLUSION: Oncogenic YB-1 indirectly enhances TGFbeta signaling cascades via Smad2 phospho-activation and may represent a promising factor for future diagnosis and therapy of breast cancer. PMID- 29187453 TI - Evaluation of the Effects of Aminonaphthoquinone Derivatives in Combination with Curcumin Against ER-positive Breast Cancer and Related Tumours. AB - BACKGROUND/AIM: Combination therapies are often explored to treat cancer. The use of curcumin as an adjuvant to current chemotherapies has been reported, whilst aminonaphthoquinones have shown potential as anticancer agents in various tumour cell lines. This study aimed at screening synthetic aminonathoquinone derivatives (Rau 008, Rau 010, Rau 015 and Rau 018) alone and in combination with curcumin for anti-breast cancer activity. MATERIALS AND METHODS: Combination effects were determined in MCF-7 breast cancer cells using combination index analyses. Synergistic anti-proliferative effects were further investigated in breast (MCF 7, MDA-MB-231), osteosarcoma (MG-63) and endometrial (HEC-1A) cancer-derived cells. RESULTS: Rau 015 (15 MUM) and curcumin (112.5 MUM) significantly reduced MCF-7, MDA-MB-231 and MG-63 cell proliferation compared to individual treatment, indicating synergistic anti-proliferative effects. Rau 018 (30 MUM) and curcumin (100 MUM) displayed similar effects in MCF-7 and MG-63 cells. CONCLUSION: We report on the potential of Rau 015 or Rau 018 as anti-breast cancer agents when combined with curcumin. PMID- 29187454 TI - P-gp Inhibition by XL019, a JAK2 Inhibitor, Increases Apoptosis of Vincristine treated Resistant KBV20C Cells with Increased p21 and pH2AX Expression. AB - The present study was designed to identify conditions that could increase the sensitivity of resistant cancer cells to antimitotic drugs. We investigated whether a Janus kinase 2 (JAK2) inhibitor used in clinical trials, XL019, sensitizes antimitotic drug-resistant KBV20C cells. XL019 reduced cellular viability and increased apoptosis in vincristine-treated KBV20C cells, independently of the JAK/signal transducer and activator of transcription (STAT) pathway. Based on the ATP-binding cassette protein B1 [ABCB1, P-glycoprotein (P gp)] inhibitory assay, we demonstrated that XL019 functions as a P-gp inhibitor in drug-resistant KBV20C cells. Considering that another JAK2 inhibitor, CEP 33779, also inhibited P-gp and sensitized drug-resistant cancer cells in a previous study, we concluded that JAK2 inhibitors can be used as P-gp inhibitors in drug-resistant cancer cells. Fluorescence-activated cell sorting, western blot, and annexin V analyses were used to further investigate the mechanism of action of XL019 in vincristine-treated KBV20C cells. XL019 induced early apoptosis of KBV20C cells in response to vincristine treatment via increased G2 phase arrest. Moreover, G2 phase arrest and apoptosis of cells co-treated with vincristine and XL019 resulted from the up-regulation of phosphorylated retinoblastoma protein (pRb), p21, and the DNA-damage protein, phosphorylated H2A histone family, member X (pH2AX). Additionally, the P-gp-inhibitory effect of XL019 was less than that of CEP-33779, and a more than 2-fold higher dose was required to sensitize vincristine-treated KBV20C cells. Furthermore, lower doses of XL019 were required to sensitize KBV20C cells to a degree similar to that obtained with the established P-gp inhibitor verapamil, suggesting that XL019 has higher specificity than verapamil. Our results showed that JAK2 inhibitors inhibited P-gp action via a direct binding mechanism, which was similar to that of verapamil. These findings indicate that JAK2 inhibitors may be promising therapeutics for the treatment of cancer that is resistant to antimitotic drugs. PMID- 29187455 TI - Comparison of PD-L1 mRNA Expression Measured with the CheckPoint Typer(r) Assay with PD-L1 Protein Expression Assessed with Immunohistochemistry in Non-small Cell Lung Cancer. AB - BACKGROUND: Immunohistochemical (IHC) assessment of programmed death-ligand 1 (PD L1) in non-small cell lung cancer (NSCLC) has become important since the development of anti-PD-1/-PD-L1 directed drugs. Various PD-L1 antibodies and cut offs have been used in different trials to predict response to these drugs, thus comparison of those studies is difficult. We compared PD-L1 mRNA expression measured by RT-qPCR with PD-L1 protein expression evaluated by IHC. Moreover, we investigated the impact of different tumour tissue acquisition methods on the reliability of PD-L1 measurement techniques. MATERIALS AND METHODS: NSCLC cases (N=22), including n=9 mediastinal lymph node biopsies acquired by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and n=5 metastases, were evaluated prospectively for PD-L1 protein on tumor cells (TC) and immune cells (IC) using E1L3N and 28-8 antibodies and PD-L1 mRNA using the CheckPoint TYPER(r) assay. RESULTS: In primary NSCLC tissues, agreement between PD-L1 mRNA and TC staining using the 28-8 antibody was excellent (K=0.85, p=0.0002). Comparing both PD-L1 antibodies against each other showed a kappa value of 0.58 (p=0.0106). In EBUS-TBNA, PD-L1 mRNA correlated perfectly with the 28-8 antibody (K=1.0, p=0.0023). PD-L1 mRNA levels significantly differed when comparing 28-8 TC staining of tumours >49% with 1-49% and 0% (p=0.0040; p=0.0081, respectively). In metastatic lesions, differences between PD-L1 mRNA and IHC became apparent (K=0.2, p=0.2525). CONCLUSION: Testing of PD-L1 mRNA and 28-8 IHC showed an excellent agreement in NSCLC samples including mediastinal lymph node biopsies. Since PD-L1 expression in >50% TC detected by 28-8 IHC can be reliably detected by RT-qPCR, quantitative PD-L1 mRNA determination should be considered as an alternative to IHC as there is no interobserver variability in RNA results. PMID- 29187456 TI - Analysis of the miRNA Profiles of Melanoma Exosomes Derived Under Normoxic and Hypoxic Culture Conditions. AB - BACKGROUND/AIM: MicroRNAs (miRNAs) transported in melanoma-derived exosomes function as intercellular messengers supporting tumor survival and progression. Hypoxia increases melanoma phenotypic plasticity, drug resistance, and metastasis. MATERIALS AND METHODS: We determined the miRNA profiles in exosomes derived from melanoma cells grown under hypoxic and normoxic conditions by microarray analyses and reverse transcription-polymerase chain reaction (RT-PCR) in order to analyze the potential influence of vesicle-transported miRNAs on cancer-related pathways and transcriptional programs. RESULTS: Despite phenotypical differences of the four cell lines used, their exosomes shared the majority of miRNAs. The levels of three miRNAs were higher in normoxic exosomes, whereas 15 miRNAs were significantly more abundant under hypoxic conditions. Pathway analysis pointed at several cellular processes contributing to proliferation, drug resistance, and modification of the tumor microenvironment, including immunosuppression. CONCLUSION: The miRNA-expression profiles of exosomes from patient-derived melanoma cells are modified by oxygen concentration and reflect the phenotypic changes of melanoma cells under different growth conditions. PMID- 29187457 TI - Transdermal Delivery of Luteinizing Hormone-releasing Hormone with Chitosan Microneedles: A Promising Tool for Androgen Deprivation Therapy. AB - Long-term administration of luteinizing hormone-releasing hormone analogs (LHRHa) is the main type of androgen-deprivation therapy (ADT) for lethal prostate cancer. A fully insertable microneedle system, composed of embeddable chitosan microneedles and a dissolvable polyvinyl alcohol/polyvinyl pyrrolidone supporting array, was developed for sustained delivery of LHRHa to the skin. A porcine cadaver skin test showed that chitosan microneedles can be fully embedded within the skin and microneedle-created micropores reseal within 7 days. The measured LHRHa loading amount was 73.3+/-2.8 MUg per microneedle patch. After applying goserelin-containing microneedles to mice, serum LH levels increased initially and then declined below baseline at day 7. In contrast, serum testosterone levels increased to reach a peak at day 14 and then declined to a castration level at day 21. Additionally, such a castration level was maintained for 2 weeks. Therefore, transdermal delivery of goserelin with embeddable chitosan microneedles can produce a castrated state in mice. Such a system is a promising, feasible means of delivering ADT. PMID- 29187459 TI - Cadherin 5 Is a Significant Risk Factor for Hematogenous Recurrence and a Prognostic Factor in Locally Advanced Gastric Cancer. AB - BACKGROUND/AIM: Cadherin 5 (CDH5) is important for adhesion in epithelial cells, and expressed in tumor cells in several malignancies. In the present study, we evaluated the clinical significance of CDH5 protein expression in locally advanced gastric cancer. MATERIALS AND METHODS: Tumor tissues obtained from 113 patients with advanced gastric adenocarcinoma who underwent gastrectomy were analyzed. RESULTS: High CDH5 expression was significantly associated with recurrence (p=0.017), especially hematological recurrence (p=0.022). High CDH5 expression was a significant risk factor for hematogenous recurrence on multivariate analysis (odds ratio[OR]=3.9, confidential interval [CI] 1.0-15, p=0.043). Patients with high CDH5 expression had a significantly shorter progression-free interval (RFI, p=0.010) than patients with low CDH5 expression. High CDH5 expression was an independent prognostic factor on multivariate analysis of RFI (hazard ratio[HR]=2.2, 95% CI 1.1-4.3, p=0.021). CONCLUSION: CDH5 may play a key role in hematogenous recurrence of advanced gastric cancer and may be a viable treatment target. PMID- 29187458 TI - Radiation Enhances the Efficacy of Antitumor Immunotherapy with an Immunocomplex of Interleukin-2 and Its Monoclonal Antibody. AB - AIM: An immunocomplex of interleukin-2 (IL-2) and its monoclonal antibody, S4B6 (IL-2/S4B6), contributes to antitumor immune systems. We investigated the antitumor efficacy of radiation (IR) combined with IL-2/S4B6 for osteosarcoma. MATERIALS AND METHODS: LM8 mouse osteosarcoma cells were inoculated into both legs of C3H mice. For groups treated with IL-2/S4B6 alone, and those treated with IR combined with IL-2/S4B6 (COMB), IL-2/S4B6 was intraperitoneally administered on days 12 and 16 after tumor cell inoculation. For groups treated with IR alone or COMB, one side leg was irradiated at 10 Gy on day 12. RESULTS: Although monotherapy with IL-2/S4B6 provided no significant tumor growth inhibition, combined therapy significantly reduced tumor volume in both irradiated and unirradiated tumors by 99% and 58%, respectively, compared to the no-treatment group, with significant induction of CD8+ T-cells in unirradiated tumors. Moreover, the combination therapy significantly prolonged overall survival. CONCLUSION: Radiation combined with IL-2/S4B6 may be a potential therapeutic option for therapy of osteosarcoma. PMID- 29187461 TI - Complete Lymph Node Dissection in Melanoma: A Systematic Review and Meta Analysis. AB - BACKGROUND: The aim of this meta-analysis was to estimate the survival after immediate complete lymph node dissection (CLND) compared to observation only (OO) or delayed CLND in patients with melanoma and lymph node metastasis. MATERIALS AND METHODS: A systematic search was performed in: PubMed, Web of Science, Cochrane Library, CINAHL, Clinical trials and Embase. Eligible studies were randomized controlled trials (RCTs) comparing: CLND with OO, or immediate CLND with delayed CLND. RESULTS: Four RCTs were included. There was no difference in melanoma-specific survival (MSS) (HR=0.91, 95% CI=0.77-1.08, p=0.29). In a sensitivity analysis, MSS was higher after immediate CLND compared to delayed CLND in patients with nodal metastasis (HR=0.63, 95% CI=0.35-0.74, p=0.0004) without evidence of heterogeneity. CONCLUSION: CLND appears to have no additional survival benefit after SNB compared to OO. However, subgroup analysis suggests a time-dependent benefit for early surgical lymph node removal compared to delayed or none. PMID- 29187460 TI - Adjuvant Breast Cancer Treatments Induce Changes in Homoarginine Level - A Prospective Observational Study. AB - AIM: To identify patients with breast cancer at risk for cardiotoxicity, we evaluated homoarginine (HA) behavior during adjuvant treatment. PATIENTS AND METHODS: Eighty-one patients received radiotherapy (RT) with or without endocrine treatment, and 19 received chemotherapy, RT and endocrine therapy. Serum HA, asymmetric dimethylarginine (ADMA) and high-sensitivity cardiac troponin T (hscTnT) were measured and echocardiography was performed before chemotherapy, and before and after RT. RESULTS: In chemo-naive tamoxifen users HA increased during RT from a median (IQR) of 2.47 (1.61-3.35) to 2.86 (1.93-4.23) MUM (p=0.028) and remained stable in patients with aromatase inhibitor and in those without endocrine therapy. Tamoxifen users were mostly spared from echocardiographic changes. In chemotherapy-treated patients, HA decreased during chemotherapy (p=0.001) from 1.46 (1.01-2.18) to 0.91 (0.71-1.29) MUM, and increased (p=0.004) to 1.19 (0.83-1.63) MUM during RT, remaining lower than at baseline (p=0.014). Echocardiographic changes were observed during chemotherapy. CONCLUSION: HA decrease during chemotherapy could indicate an increased risk of cardiovascular morbidity. Additionally, HA increase in tamoxifen users may reflect a cardioprotective effect of tamoxifen. PMID- 29187463 TI - Multi-Database Description of Primary Splenic Diffuse Large B-Cell Lymphoma. AB - BACKGROUND/AIM: Stage I splenic diffuse large B-cell lymphoma (DLBCL) is rare and there are few data to guide management. We sought to further define prognosis and outcomes. MATERIALS AND METHODS: We utilized the Surveillance, Epidemiology, and End Results registry to identify patients with stage I splenic DLBCL diagnosed 1973-2013. Patients were divided into two cohorts based on the year of diagnosis (1983-2005; 2006-2013) as rituximab was approved by the U.S. Food and Drug Administration in 2006 for first-line treatment of DLBCL. RESULTS: Utilization of splenectomy decreased after the approval of rituximab (82% pre- versus 72% rituximab-era). Disease-specific and overall survival were greater with splenectomy [hazard ratio (HR)=0.57, p=0.04; and HR=0.66, p=0.03, respectively], but this benefit was only seen in the pre-rituximab cohort, not in the rituximab era cohort. There was a trend toward improved overall survival with the introduction of rituximab (HR=0.75, p=0.054). CONCLUSION: Utilization of splenectomy for stage I splenic DLBCL has decreased with the introduction of rituximab without compromising outcomes. PMID- 29187462 TI - Control of Nausea Based on Risk Analysis in Patients with Esophageal and Gastric Cancer Who Received Cisplatin-based Chemotherapy. AB - BACKGROUND: Cisplatin is commonly used for esophageal and gastric cancer, but has a high emetic risk. Although the control of vomiting is favorable, nausea is still poorly controlled in patients receiving cisplatin-based regimens. The present study was designed to determine the risks for cisplatin-induced nausea. The effect of olanzapine, an antipsychotic drug, as an antiemetic for patients with risk of poor control of nausea was subsequently examined. PATIENTS AND METHODS: The prevalence of antiemetic medication and the control of nausea and vomiting were retrospectively examined in patients with esophageal or gastric cancer receiving the first cycle of cisplatin-based chemotherapy. Risks for nausea were analyzed by multivariate logistic regression analysis, in which threshold for age and cisplatin dose wer assessed by receiver operating characteristic curve analysis. RESULTS: A total of 186 patients received cisplatin-based regimens during January 2011 and December 2016. Guideline consistent antiemetic medication was administered to all patients. Although the rate of no vomiting was high (93%), the rate of non-significant (grade 2 or more) nausea was insufficient (64%) during the overall period. Risk analysis showed that cisplatin dose of 50 mg/m2 or more and female gender were significant risks for nausea. Addition of olanzapine, but not of prochlorperazine, to the standard antiemetic medication was effective in suppressing nausea in patients who experienced nausea in the first cycle. CONCLUSION: Being female and cisplatin doses at 50 mg/m2 or more were demonstrated to increase risk for nausea. Addition of olanzapine to the standard medication was effective in preventing nausea in high-risk patients with esophageal and gastric cancer. PMID- 29187465 TI - Esophagogastric Junction Carcinomas - Discriminating Histological Types Through Immunohistochemistry. AB - BACKGROUND/AIM: Although differentiating squamous cell carcinoma (SCC) from adenocarcinoma (AC) at the esophagogastric junction (EGJ) is important for the choice of treatment, this can occasionally be difficult with small biopsy specimens. Therefore, the purpose of this study was to determine the most useful immunomarker panel for discriminating between SCC and AC of the EGJ. MATERIALS AND METHODS: We analyzed 15 SCCs and 26 ACs of the EGJ obtained surgically using immunohistochemistry. RESULTS: The sensitivities of p40, p63 and cytokeratin 5/6 were 100% with specificities of 88%, 46% and 81%, respectively, for SCC. The sensitivities of CAM5.2, caudal-type homeobox 2 (CDX2), mucin-5AC (MUC-5AC) and MUC-6 were 100%, 81%, 77% and 85% with specificities of 27%, 100%, 87% and 87% for AC. CONCLUSION: We demonstrated that a two-marker panel of p40 and CDX2 is highly sensitive and specific. PMID- 29187464 TI - Androgen Receptor in Stage I-II Primary Breast Cancer -Prognostic Value and Distribution in Subgroups. AB - BACKGROUND/AIM: The value of androgen receptor (AR) in breast cancer has gained renewed interest as a prognostic and treatment predictive biomarker. The aims of this work were to study the associations and the prognostic value of AR in patients from two clinical cohorts. MATERIALS AND METHODS: Cohort 1 included 208 premenopausal, node-negative patients of whom 87% had received no adjuvant medical treatment; cohort 2 consisted of 263 patients with stage II disease who had all received 2 years of adjuvant tamoxifen. A semi-quantitative assessment of nuclear AR expression divided into five groups (0-1%, 2-10%, 11-50%, 51-75%, and 76-100%) was performed. Survival analyses, stratified by cohort, were performed using both a trend-test and a cut-off of >10% for positivity. RESULTS: A total of 76% of all patients were AR+, and 89%, 48%, and 23% of the estrogen receptor positive, negative, and triple-negative, respectively. In Cox regression, stratified by cohort, AR divided into five groups was a prognostic factor for 5 year distant disease-free survival with a hazard ratio of 0.86 per step in fraction score (p=0.018). With a predefined cut-off at 10%, moderate evidence of an effect remained (Hazard Ratio=0.67, p=0.077). In multivariable analysis, AR did not retain an independent prognostic value. CONCLUSION: AR is a weak, however, not independent prognostic factor for distant metastasis. Although the prognostic value of AR may be questionable, the study identified a subset of AR positive triple-negative patients as being potential candidates for AR-directed therapy for which further studies are warranted. PMID- 29187466 TI - A Comparison of the Performance of EndoPredict Clinical and NHS PREDICT in 120 Patients Treated for ER-positive Breast Cancer. AB - BACKGROUND: Computational algorithms, such as NHS PREDICT, have been developed using cancer registry data to guide decisions regarding adjuvant chemotherapy. They are limited by biases of the underlying data. Recent breakthroughs in molecular biology have aided the development of genomic assays which provide superior clinical information. In this study, we compared the performance in risk stratification of EndoPredict Clinical (EPClin, a composite of clinical data and EndoPredict) and PREDICT in a cohort of patients with breast cancer considered potential candidates for chemotherapy by the clinicians. MATERIALS AND METHODS: One hundred and twenty patients with biopsy-proven oestrogen receptor positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancer who underwent surgery were included. EPClin and PREDICT were determined for every tumour, and the results were compared. RESULTS: Using EPClin scores performed on 120 tumours, the cohort was stratified into low- (n=60) and high-risk (n=60) groups leading to 50% reduction in total chemotherapy prescriptions. PREDICT differentiated the patients into low- (n=45), intermediate- (n=33), and high-risk groups (n=42). Discordance between scores was demonstrated for 50 (41.66%) tumours. Nine (20%) out of 45 patients with low PREDICT scores had high EPClin scores and would otherwise not have received chemotherapy if the NHS PREDICT tool had been used alone. Eight (19%) out of 42 patients at high risk by PREDICT were reclassified as being at low risk by EPClin and avoided adjuvant chemotherapy. The sensitivity, specificity, positive predictive value and negative predictive value for NHS PREDICT to predict the potential need for chemotherapy as determined by EPClin were 85%, 51%, 68% and 80%, respectively. CONCLUSION: To our knowledge, this is the first clinical study to compare EPClin and PREDICT. The data indicate that computational algorithms such as NHS PREDICT may not accurately predict the need for chemotherapy leading to overtreatment, undertreatment or uncertainty and anxiety in a significant proportion of patients. This underscores the importance of more personalized prognostic tools. PMID- 29187467 TI - Diagnostic Performance of Multiparametric Magnetic Resonance Imaging and Fusion Targeted Biopsy to Detect Significant Prostate Cancer. AB - BACKGROUND/AIM: Multiparametric magnetic resonance imaging combined with ultrasound-fusion-targeted biopsy of the prostate intends to increase diagnostic precision, which has to be clarified. PATIENTS AND METHODS: We performed multiparametric magnetic resonance imaging followed by ultrasound-fusion-guided perineal biopsy in 99 male patients with elevated prostate-specific-antigen and previous negative standard biopsy-procedures. RESULTS: In 33/99 patients (33%) no malignancy could be confirmed by histopathology. Low-grade carcinomas (Gleason Score 6+7a) were found in 42/66 (64%) and high-grade carcinomas (Gleason-Score >=7b) in 24/66 (36%) men. A high-grade carcinoma corresponded to PI-RADS 4 or 5 (suspected malignancy) in 21/24 cases, which accounted for a sensitivity of 88% and negative-predictive-value of 85% (p=0.002). Differentiation between high-/low grade carcinomas (Gleason-Score <=7a vs. >=7b) by means of PI-RADS related to a sensitivity of 88% and a negative-predictive-value of 70% (p=0.74). CONCLUSION: The results support the view that multiparametric magnetic resonance imaging/ultrasound-fusion-guided biopsy promotes considerably higher detection rates of clinically relevant prostate malignancies than do conventional diagnostic procedures. With regard to differentiation between high- and low-grade carcinomas, no significant difference was demonstrated. PMID- 29187468 TI - Modeling CA-125 During Neoadjuvant Chemotherapy for Predicting Optimal Cytoreduction and Relapse Risk in Ovarian Cancer. AB - AIM: To investigate the prognostic value of modeled CA-125 kinetic parameters regarding surgery outcomes and time to second-line chemotherapy in a population of ovarian cancer patients treated with neoadjuvant chemotherapy followed by interval cytoreduction. PATIENTS AND METHODS: This retrospective study included consecutive patients with FIGO stage IIIc/IV ovarian cancer treated between 2006 and 2014. We characterized CA-125 kinetics and identified modeled kinetic parameters. RESULTS: Fifty four patients were included. KELIM (modeled CA-125 elimination rate constant) was an independent predictive parameter of optimal cytoreduction (OR=0.18; 95% CI=0.04-0.69; p=0.02). In the optimal cytoreduction population (40 patients, 74.1%), E50 (concentration producing 50% of the maximum chemotherapy effect) was a significant prognostic parameter regarding time to second-line chemotherapy (HR=0.38; 95% CI=0.173-0.854; p=0.019). CONCLUSION: We identified CA-125 modeled kinetic parameters during neoadjuvant chemotherapy harboring potential predictive values regarding the likelihood of optimal cytoreduction, along with time to second-line chemotherapy in optimally cytoreduced patients. PMID- 29187469 TI - Brachytherapy for Buccal Cancer: From Conventional Low Dose Rate (LDR) or Mold Technique to High Dose Rate Interstitial Brachytherapy (HDR-ISBT). AB - BACKGROUND/AIM: To examine the effectiveness of newly-installed high-dose-rate interstitial brachytherapy (HDR-ISBT) for buccal cancer. PATIENTS AND METHODS: We retrospectively reviewed 36 patients (25 men and 11 women) with buccal cancer treated with curative brachytherapy with or without external radiotherapy with a median follow-up of 99 months. A total of 15 HDR-ISBT (median 48 Gy/ 8 fractions, range=24-60 Gy) patients were compared to conventional 15 cases LDR-ISBT (70 Gy, range=42.8-110 Gy) and 7 molds techniques (15 Gy, range=9-74 Gy). A total of 31 patients also underwent external radiotherapy (30 Gy, range=24-48 Gy). They comprised of 3T1, 23 T2, 8 T3, 3 T4 including 11 node positive cases. RESULTS: HDR-ISBT provided 82% of local control rate at 5 years, whereas conventional brachytherapy showed 72% [p=0.44; LDR-ISBT (65%), mold therapy (85.7%)]. Patients with early lesions (T1-2 or stage I-II) showed better local control rates than those with advanced lesions (T3-4 or stage III-IV). Severe late grade 3 complications developed in two patients treated with LDR-ISBT and EBRT. There is no significant difference in toxicity grade <=2 between conventional brachytherapy (5/15=33%) and HDR-ISBT (7/32=32%, p=0.92). CONCLUSION: HDR-ISBT achieved good and comparable local control rates to conventional brachytherapy without elevating the toxicity. PMID- 29187470 TI - The Genomic Alterations of 5alpha-Reductases and Their Inhibitor Finasteride's Effect in Bladder Cancer. AB - BACKGROUND/AIM: Since androgens affect urothelial bladder cancer (UBC), we examined whether 5alpha-reductases (5-AR) have genomic alterations in UBC and whether 5alpha-reductase inhibitors (5-ARI) affect UBC. MATERIALS AND METHODS: The cBioPortal was used to analyze genomic alternations of 5-ARs in UBC cancer genomic datasets. Next, we used the Taiwan National Health Insurance Research database to conduct a population-based case-control study to investigate the effect of a 5-ARI, finasteride on UBC incidence. We also performed an XTT assay to examine the direct effect of finasteride on UBC cells. RESULTS: We found that 5-AR genomic alternations were observed in 29% of UBC patients and patients with alternations had shorter disease-free survival. Also, the use of finasteride with >180 cDDDs reduced the risk of UBC. Finasteride could directly inhibit UBC cell growth. CONCLUSION: Based on our findings, we concluded that 5-AR could be explored as a therapeutic target for UBC with 5-ARIs. PMID- 29187471 TI - Resectability and Vascular Management of Retroperitoneal Gynecological Malignancies: A Large Single-institution Case-Series. AB - BACKGROUND/AIM: To report on morbidity and oncological outcomes in a consecutive series of gynecological malignancies involving the vascular district. PATIENTS AND METHODS: We retrospectively evaluated a consecutive series between 1/2015 and 1/2017 with suspicious gynecological malignancies involving the vascular district. Peri-operative data and survival rates were computed. RESULTS: Eight hundred-four women with gynecological malignancies were admitted for major oncologic surgery during the study period, and among them, 50 cases (6.2%) showed vascular involvement. Twenty-seven and 23 patients were submitted to minor and major vascular procedures, respectively. R0 resection was achieved in 44 patients. There were no perioperative mortalities. Major postoperative complications occurred in 6 patients (12.0%). The 2-year disease free survival (DFS) was 67% if R0 resection was achieved. In patients with positive pathological margins (n=2), the 2-year DFS was 33%. CONCLUSION: Vascular procedures can be safely performed with a proper pre-operative planning and may not be an impediment to major gynecological oncological surgery. PMID- 29187472 TI - Pilomatrixoma of the Neck/Shoulder Region Mimicking a Rapidly Growing Neoplasm of Peripheral Nerve Sheath Origin in Neurofibromatosis Type 1. AB - Neurofibromatosis type 1 (NF1) is an autosomal dominant hereditary disorder. Neurofibroma is the most common neoplasm of this disease. This lesion is characterized by circumscribed soft or knotty skin tumors derived from peripheral nerve sheath cells. Numerous other neoplasms have been described for this tumor predisposition syndrome. This case report adds the diagnostic and therapeutic procedures in the case of an NF1 patient in whom the rapidly growing, nodular, subcutaneous tumor initially led to the suspicion of a malignant neoplasm. The tumor proved to be pilomatrixoma, which closely adhered to a neurofibroma. PMID- 29187473 TI - Melanoma of the Vagina: Case Report and Systematic Review of the Literature. AB - BACKGROUND: Primary melanoma of the vagina (PMV) is a rare entity. The prognosis of women with PMV is poor and there is no standardized therapy for this type of malignancy. We present the case of a 72-year-old woman with PMV (cT2, pN0, M0). CASE REPORT: Imaging studies showed no evidence of regional or distant metastases. Molecular analysis demonstrated wild-type B-Raf proto-oncogene, serine/threonine kinase (BRAF). Staging laparoscopy with pelvic lymphadenectomy and subsequent radiotherapy with 60 Gy delivered as pelvic teletherapy and vaginal brachytherapy was applied. Systematic literature review: A total of 805 cases of PMV were identified. Most lesions were melanotic (65%) and localized (66%), whereas amelanotic (35%) and primary advanced lesions (34%) were only seen in a minority of patients. BRAF mutation was detected in none out of 33 cases, tumor protein 53 (TP53) mutations and mast/stem cell growth factor receptor CD117 (KIT) amplification were identified in one case each. The most common treatment was surgery, reported in 43% of cases. Surgery combined with adjuvant radiotherapy, adjuvant immunotherapy (mostly with interferon-alpha), or adjuvant chemotherapy were given in 35%, 8%, and 3% of cases, respectively. Radiotherapy or chemotherapy as sole treatments were used in 5% and 1% of patients, respectively. Among patients with recurrence, chemotherapy (mostly dacarbazine) alone or in combination with surgery, radiotherapy or immunotherapy was the most common treatment in 61% of cases. The mean durations of recurrence-free and overall survival were 16.4 and 22.2 months, respectively. CONCLUSION: PMV is a rare malignancy with a poor prognosis. Surgery, radiotherapy, and immunotherapy with interferon-alpha are the mainstay of treatment for localized disease, while chemotherapy with dacarbazine is mostly used for unresectable and recurrent disease. No data on the clinical value of immune checkpoint inhibitors in PMV have been published. PMID- 29187474 TI - Plasma Glutathione Peroxidase (GPX1) Levels and Oxidative Stress in Gallstone Patients Operated with Two Different Cholecystectomy Techniques: A Randomized Study with Special Reference to Cancer Patients. AB - BACKGROUND/AIM: The plasma glutathione peroxidase (GPX1) levels in gallstone patients operated with laparoscopic cholecystectomy (LC) or minicholecystectomy (MC) versus cancer patients is unknown. PATIENTS AND METHODS: Initially, 114 patients with symptomatic gallstone disease were randomized into LC (n=53) or MC (n=61) groups. Plasma levels of C-reactive protein (hs-CRP) and the oxidative stress marker GPX1 were measured at three time points; before (PRE), immediately after (POP1) and 6 hours after operation (POP2). The end-point of our study was to determine a correlation between the plasma hs-CRP and GPX1 levels in the LC and MC patients versus cancer patients. RESULTS: The plasma GPX1 levels preoperatively and following surgery in the LC and MC patients versus cancer patients were quite similar (p=0.509, p=0.578, p=0.882, respectively). The patients with inflammation of the gallbladder wall (IGW) versus no-IGW had significantly higher plasma GPX median (interquartile range) levels preoperatively (11.5; 6.2-17.4 vs. 8.0; 5.6-14.5, p=0.033) and the GPX values following surgery (POP1, 11.4; 7.8-14.7 versus 7.3; 4.4-11.0, p=0.019 and POP2, 11.5; 7.1-16.2 versus 9.4; 4.2-13.1, p=0.027). The IGW in patients with LC and MC groups combined, correlated significantly to the plasma CRP levels preoperatively (r=0.280, p=0.005) and the CRP values following surgery (POP1, r=0.295, p=0.003 and POP2, r=0.338, p=0.001) and the GPX1 values postoperatively (POP1, r=0.319, p=0.001 and POP2, r=0.243, p=0.026) and to the length of the skin incision (r=0.248, p=0.009). CONCLUSION: The plasma GPX1 levels preoperatively and following surgery in the LC and MC patients versus cancer patients were quite similar. However, the inflammation of the gallbladder wall (IGW) correlated significantly with plasma GPX1 and hs-CRP values suggesting that inflammation and oxidative stress are related. PMID- 29187475 TI - Reliable Radiation Technique to Minimize Ovarian Dose During Radiation Prophylaxis of Heterotopic Ossification. AB - BACKGROUND/AIM: Scattered radiation during radiotherapy (RT) directed at the hip joint poses concerns about ovarian function in patients of reproductive age. Here, we report the impact of using a split-beam technique (SBT) and different photon energies on the total ovary dose during radiation prophylaxis of heterotopic ossification (HO). PATIENTS AND METHODS: This was a single institution, retrospective study of 32-patients with traumatic acetabular fractures (TAF). All underwent surgery followed by CT-based-RT within 72 h in a single fraction of 700 cGy. Ipsilateral (IL) and contralateral (CL) ovaries (OV) were contoured separately and dose volume histograms (DVH) generated. Additional planning trials were created for each patient by utilizing a SBT medially and by using different photon energies (6-18 MV) to investigate the difference in ovary dose among these maneuvers. RESULTS: The median Mean-dose delivered to ILOV was 59 cGy and the median Max-dose was 177 cGy. CLOV median Mean-dose was 6 cGy and median Max-dose was 10 cGy. SBT at the medial edge of the field led to a 27% and 22% dose reduction in the median Mean and Max. doses, respectively, to ILOV; 9% and 5% reduction was seen in the median Mean and Max. doses, respectively, to CLOV. Higher photon energies (10-18 MV) led to an additional 28% and 16 % reduction in median Mean and Max. doses, respectively, to ILOV when compared to those from 6 MV. The CLOV median Mean dose was reduced by 18% and the Max. dose was reduced by 12%. CONCLUSION: A biologically significant radiation dose is delivered to the ovaries during HO radiation prophylaxis at the hip joints. Ipsilateral ovarian dose could be reduced by half and contralateral by one quarter by using CT-based treatment planning with a medial SBT and photon energies above 6 MV. We suggest using no more than 10 MV to minimize neutron contamination. Those techniques should be the standard of care as it provides a reliable method for minimizing the radiation dose to the ovaries, consequently, maximizing female fertility preservation during HO radiation prophylaxis. All female patients in childbearing age should be fully informed about ovarian radiation exposure and possible temporary alteration in ova production and morphology. PMID- 29187476 TI - A Case of the Resected Lymphohistiocytoid Mesothelioma: BAP1 Is a Key of Accurate Diagnosis. AB - BACKGROUND: Malignant mesothelioma (MM) is a well-known malignant tumor that occurs in the pleura and is histopathologically classified into three subtypes. Lymphohistiocytoid mesothelioma (LHM) is considered a variant of epithelioid MM, and few cases have been reported. First case of LHM was reported by Henderson et al. in 1988. It is difficult to precisely diagnose LHM, and it is often misdiagnosed as reactive mesothelial cell proliferation. CASE REPORT: An 82-year old man, with the smoking history of nine pack-years, was referred to our Department due to an abnormal shadow and pleural effusion in the left lung field on the chest X-ray imaging. His occupation was a teacher through his life without any asbestos exposure. Computed tomography (CT) and 18F-fluorodeoxyglucose position emission tomography showed a tumor which was suggestive of malignancy on the left chest wall, with the possible invasion into the left 2nd to 4th ribs. He underwent a CT-guided biopsy and a thoracentesis, but the tumor was shown to be a benign tumor indicative of a reactive mesothelial cell proliferation. Then, he underwent a surgical resection and the tumor was suspected of liposarcoma macroscopically. Histological and immunohistochemical findings were suggestive of mesothelial lesion, such as nodular histiocytic or mesothelial hyperplasia. However, loss of BAP1 and no p16 homozygous deletion in the tumor cells led to the diagnosis of LHM, not a benign lesion. PMID- 29187477 TI - Proteins Annexin A2 and PSA in Prostate Cancer Biopsies Do Not Predict Biochemical Failure. AB - BACKGROUND/AIM: We previously reported the use of mass spectrometry and western blotting to identify proteins from tumour regions of formalin-fixed paraffin embedded biopsies from 16 men who presented with apparently localized prostate cancer, and found that annexin A2 (ANXA2) appeared to be a better predictor of subsequent biochemical failure than prostate-specific antigen (PSA). MATERIALS AND METHODS: In this follow-up study, ANXA2 and PSA were measured using western blotting of proteins extracted from biopsies from 37 men from a subsequent prostate cancer trial. RESULTS: No significant differences in ANXA2 and PSA levels were observed between men with and without biochemical failure. The statistical effect sizes were small, d=0.116 for ANXA2, and 0.266 for PSA. CONCLUSION: ANXA2 and PSA proteins measured from biopsy tumour regions are unlikely to be good biomarkers for prediction of the clinical outcome of prostate cancer presenting with apparently localized disease. PMID- 29187478 TI - The Relationship Between Peripheral Neuropathy Induced by Docetaxel and Systemic Inflammation-based Parameters in Patients with Breast Cancer. AB - BACKGROUND/AIM: Docetaxel often induces peripheral neuropathy (PN). The aim of this study was to elucidate the relationship between PN and systemic inflammation parameters, namely the neutrophil-to-lymphocyte ratio (NLR), platelet-to lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR). PATIENTS AND METHODS: We retrospectively evaluated 67 patients with breast cancer who were treated with docetaxel. Thirty patients (44.8%) had received previous chemotherapy including anthracycline. RESULTS: Overall, 51 patients (76.1%) experienced PN. All the parameters increased with the number of administered courses of docetaxel. In an analysis of patients without previous chemotherapy, those suffering from PN had a significantly higher NLR at the first and third cycles than those not suffering from PN (2.9 vs. 2.0, and 3.1 vs. 2.6, respectively, both p<0.05), and the MLR at the first cycle was also significantly higher in those with PN than in those without (0.18 vs. 0.15, p<0.05). CONCLUSION: Systemic inflammation appears to contribute to the occurrence of PN induced by docetaxel. PMID- 29187479 TI - Predictive Significance of Thymidylate Synthase Expression in Non-small Cell Lung Cancer. AB - BACKGROUND/AIM: To date, many studies have suggested that thymidylate synthase (TS) could be used as a prognostic and predictive marker in non-small cell lung cancer (NSCLC) patients. However, results have been contradictory. The aim of this study was to evaluate TS mRNA levels in tumor tissue of NSCLC patients who underwent complete surgical resection and to analyze its prognostic and predictive potential. MATERIALS AND METHODS: The study group consisted of 64 patients who underwent curative lung resection. Paired lung tissue samples were taken directly from the tumor tissue and from adjacent, histologically cancer free lung tissue. The quantitative estimation of TS expression was performed by reverse transcription real-time polymerase chain reaction (RT-qPCR). The relationship between TS expression level and disease-free interval (DFI) and overall survival (OS) was analyzed. RESULTS: There was significantly higher TS expression in NSCLC tumor tissue comparing to normal lung tissue. In the group of patients who received adjuvant chemotherapy based on platinum derivatives in combination with paclitaxel or gemcitabine, we found shorter DFI (p=0.0473) and OS (p=0.0053) in those with high expression of TS. CONCLUSION: Our results demonstrated the relationship of high tumor tissue TS levels to adverse prognosis in patients undergoing adjuvant chemotherapy. TS is a non-specific tumor marker with respect to NSCLC, therefore we think that its best use would be as a member of the panel of predictors of adjuvant treatment efficacy. PMID- 29187480 TI - Clinical Efficacy of Carbon Ion Radiotherapy for Unresectable Chondrosarcomas. AB - BACKGROUND: Carbon ion radiotherapy has precise dose distribution and high biological effectiveness and is likely a promising therapy for patients with sarcomas. We evaluated the outcomes of carbon ion radiotherapy in patients with unresectable chondrosarcomas. PATIENTS AND METHODS: A retrospective analysis of 75 tumors in 73 patients treated with carbon ion radiotherapy was performed. There were 26 spinal, 38 pelvic, and 11 other types of tumors. Seventy conventional and five dedifferentiated chondrosarcomas were treated in 69 and four patients, respectively. RESULTS: The median follow-up period was 49.4 (range=6.4-146.4) months. The 5-year local control, overall survival, and disease free survival rates were 53%, 53%, and 34%, respectively. By multivariate analysis, tumor volume and histological grade were significantly related to overall and disease-free survival. Five patients required surgical intervention because of adverse events in the bones. CONCLUSION: Carbon ion radiotherapy might be a treatment option for unresectable chondrosarcoma. PMID- 29187481 TI - Pre-surgical Multiparametric Assessment of Breast Lesions Using 3-Tesla Magnetic Resonance. AB - BACKGROUND/AIM: The aim of this study was to evaluate experience with multiparametric breast imaging on 3-Tesla magnetic resonance (3T-MRI) scanner using a dedicated 18-channel coil compared to histological findings in women after surgery. MATERIALS AND METHODS: The study included 100 women with 105 Breast Imaging Reporting and Data System (BI-RADS) 4 to 6 lesions by mammography who were examined using 3T-MRI and subsequently underwent surgery. MRI included non-contrast T1, T2 and T2 short tau inversion recovery (STIR) sequences, diffusion-weighted imaging with apparent diffusion coeficient maps, postcontrast dynamic study and single-voxel MRI spectroscopy. The results were compared to those of histopathological examination. RESULTS: A sensitivity of 98.68% was found for the whole population, with a specificity of 86.20%. The most valuable findings were diffusion restriction with sensitivity of 90.79% and specificity of 89.66%, and increased choline in the spectrum with sensitivity of 68.42% and specificity of 93.10%. Evaluation of the enhancement curve had sensitivity of 45.05% and specificity of 72.41%. In examination of lymph nodes, 3T-MRI had sensitivity of 92.59% and specificity of 93.87%. CONCLUSION: Multiparametric 3T MRI breast imaging shows excellent results in evaluation of breast cancer compared to histological findings, both for primary tumor and nodal metastases. The greatest contribution to improving diagnostic performance is the evaluation of diffusion. PMID- 29187482 TI - Predictors of Cure of Intrahepatic Cholangiocarcinoma After Hepatic Resection. AB - BACKGROUND/AIM: Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer after hepatocellular carcinoma, and has a poor prognosis. Surgical resection is the only option for a cure of ICC. Here we attempted to define the cure rate after hepatic resection for ICC and to identify the predictors for a cure. PATIENTS AND METHODS: Among the 96 patients who underwent R0 resections for primary ICC between 1990 and 2011 at the Kumamoto University Hospital and Kyushu University Hospital, those who were followed for >=5 years after surgery were enrolled. "Cure" was defined as recurrence-free survival (RFS) of >=5 years after surgery. RESULTS: A total of 81 patients were eligible. A cure was achieved in 37 patients (45.7%). The 5-year overall survival and RFS rates were 55.0% and 41.7%, respectively. A multivariate logistic regression analysis identified the absence of lymph node metastasis (relative risk (RR) 7.5, p=0.011) and the absence of microvascular invasion (RR 5.5, p=0.0137) as the independent predictors of achieving a cure. CONCLUSION: R0 resections achieved a cure in 45.7% of this series of ICC patients. The predictors of a cure identified here, i.e., absence of lymph node metastasis and absence of microvascular invasion, could contribute to the selection of patients who are not candidates for adjuvant chemotherapy. PMID- 29187483 TI - Palonosetron Prevents Highly Emetogenic Chemotherapy-induced Nausea and Vomiting in Oral Cancer Patients. AB - BACKGROUND/AIM: To evaluate the efficacy of palonosetron in preventing acute and delayed nausea and vomiting in patients receiving highly emetogenic chemotherapy (HEC) in oral cancer patients. PATIENTS AND METHODS: Oral cancer patients receiving HEC were enrolled; among the 40 patients, 87 courses of chemotherapy were administered. On day 1, 0.75 mg palonosetron was intravenously administrated just before chemotherapy. RESULTS: The primary endpoint was the proportion of patients with a complete response (CR) and the secondary endpoint was the proportion of patients with complete control (CC) during the acute and delayed phase. During the acute phase, 86 of 87 courses (98.9%) had CR and 84 of 87 courses (96.6%) had CC. During the delayed phase, 84 of 87 courses (96.6%) had CR and 70 of 87 courses (80.5%) had CC. CONCLUSION: Palonosetron is effective at preventing HEC-induced chemotherapy-induced nausea and vomiting (CINV) in oral cancer chemotherapeutic regimens in the acute and delayed phases. PMID- 29187484 TI - Phase II Study of Concurrent Chemoradiotheapy Using Nedaplatin for Locally Advanced Uterine Cervical Carcinoma (KGROG0501): Final Results. AB - AIM: This phase II study using nedaplatin evaluated the effectiveness and safely of concurrent chemoradiotherapy for locally advanced uterine cervical carcinoma. PATIENTS AND METHODS: Patients met the following eligibility criteria,: International Federation of Gynecology and Obstetrics (FIGO) stage Ib, IIa, IIb with bulky tumor (>=40 mm) or pelvic lymph node swelling (>=10 mm), in FIGO stage IIIa, IIIb or IVa. Treatment adopted external radiation therapy combined with intracavitary brachyhtherapy using weekly nedaplain at 30 mg/m2 totaling five cycles. The primary endpoint was 3-year overall survival. RESULTS: From June 2005 to May 2010, 45 eligible patients with uterine cervical carcinoma were registered. Histopathology was squamous cell carcinoma in 36 and adenocarcinoma in nine. The median follow-up period was 39 months. The 3-year overall survival rate was 73.0% (95% confidence interval=56.2-84.2%). No severe acute or late toxicities occurred. CONCLUSION: This phase II study showed external radiation therapy combined with intracavitary brachyhtherapy using weekly nedaplain to be effective and safe. PMID- 29187485 TI - Primary Urinary Tract Lymphoma: Rare but Aggressive. AB - BACKGROUND: Primary urinary tract lymphoma (PUTL) is an uncommon disease with only a few case reports in the literature. MATERIALS AND METHODS: Information about 1,264 patients diagnosed between 1983 and 2013 with PUTL was extracted from the Surveillance, Epidemiology and End Results database. Kaplan-Meier curves and multivariable regression analysis were used to analyze the survival and identify prognostic factors. A comparison of nodal diffuse large B-cell lymphoma (DLBCL) with PUTL DLBCL was performed. In addition, we compared the characteristics of kidney and bladder lymphoma. RESULTS: PUTL incidence was 1 case/1,000,000 people per year. DLBCL was found to be the predominant histology. Five-year overall survival and cancer-specific survival were 49% and 58%, respectively. DLBCL histology, male gender, stage III-IV disease, and advanced age were found to be poor prognostic factors. Surgery may be beneficial. Urinary tract DLBCL has a worse prognosis than nodal DLBCL. CONCLUSION: To our knowledge, this is the largest population-based study of PUTL in the literature. The survival of patients has not improved in the era of modern therapies therefore new treatments are needed. PMID- 29187486 TI - Relationship Between Preoperative Sarcopenia Status and Immuno-nutritional Parameters in Patients with Early-stage Non-small Cell Lung Cancer. AB - BACKGROUND: Although the skeletal muscle in the region of the third lumbar vertebra (L3) is generally assessed in order to judge sarcopenia, not every patient with non-small cell lung cancer (NSCLC) undergoes computed tomography including the L3 region. We hypothesized that immuno-nutritional parameters could predict the existence of sarcopenia in patients with NSCLC. AIM: The aim of this study was to retrospectively investigate the correlation between preoperative sarcopenia and immuno-nutritional parameters in patients with early-stage NSCLC. PATIENTS AND METHODS: We selected 147 of patients with pathological stage I NSCLC who underwent preoperative measurement of immuno-nutritional parameters and CT including the L3 region. RESULTS: Preoperative sarcopenia was significantly associated with female gender (p=0.0003) and poor prognosis (p=0.0322). In Kaplan Meier analysis of overall survival (OS) by preoperative sarcopenia status, the sarcopenic group had significantly shorter OS than the non-sarcopenic group (5 year OS: 87.27% vs. 77.37%, p=0.0131, log-rank test). In multivariate analysis, the preoperative sarcopenia status (hazard ratio=5.138; 95% confidence interval=2.305-11.676; p<0.0001) was an independent prognostic factor. Preoperative sarcopenia status was significantly related to controlling nutritional status score (p=0.0071) and Geriatric Nutritional Risk Index (GNRI) (p<0.0001). Spearman's correlation test showed good significant correlation between preoperative sarcopenia status and GNRI (r=0.348, p<0.0001). CONCLUSION: The preoperative GNRI is a simple and useful predictor for existence of preoperative sarcopenia which was associated with poor outcome in patients with early-stage NSCLC. PMID- 29187487 TI - Stereotactic Body Radiation Therapy in Primary and Metastatic Liver Disease. AB - BACKGROUND/AIM: The aim of this study was to investigate the treatment outcomes and toxicities in patients with liver disease treated by Stereotactic Body Radiation Therapy (SBRT). PATIENTS AND METHODS: From 2007 to 2016, 43 patients with 58 lesions (6 primary and 37 metastatic liver tumors) were treated with SBRT. RESULTS: Local Control was reached in 47 out of 58 (81%) treated lesions with 12 and 24-month rates of 81% and 74% respectively. The progression-free survival at 12 and 24 months was 42% and 36%, respectively. The disease specific survival at 12 and 24 months was 74% and 46% respectively. Median overall survival (OS) was 20 months and the rates of OS were 74% and 46% at 12 and 24 months respectively. Toxicity was very low consisting mainly of Grade 1 and 2. CONCLUSION: SBRT provides good local control for both primary and metastatic liver lesions, with minimal toxicity. PMID- 29187488 TI - Predictive Factors and a Survival Score for Patients Irradiated for Metastatic Spinal Cord Compression from Carcinoma of the Salivary Glands. AB - AIM: To our knowledge, this is the first study focusing on metastatic spinal cord compression (MSCC) from carcinoma of the salivary glands. PATIENTS AND METHODS: Nine patients receiving radiation alone were evaluated for improvement of motor deficits, post-radiation gait function and survival. RESULTS: Of nine characteristics (radiation program, age, sex, additional metastases to bone or to other organs, dynamic of motor deficits, pre-radiation gait function, number of vertebrae affected by MSCC, general condition), strong trends were found for associations between improved motor deficits and their dynamic (p=0.05), post radiation gait function and pre-treatment ambulatory status (p=0.08) and between survival and additional metastases to other organs (p=0.07), dynamic of motor deficits (p=0.07) and general condition (p=0.07). In addition, a survival score was created. Patients with 2-3 points had a significantly better 6-month survival than those with 0-1 points (100% vs. 0%, p=0.027). CONCLUSION: Characteristics predicting outcomes identified in this study and the new survival score can guide physicians when making treatment decisions. PMID- 29187489 TI - Pancreatic Mucinous Cystic Neoplasm Communicating with Main Pancreatic Duct: An Unrecognized Presentation of Pancreatic Mucinous Neoplasm? AB - Mucinous cystic neoplasms (MCNs) and intraductal papillary mucinous neoplasms (IPMNs) are two well recognized entities of precursor cystic lesions of pancreatic duct adenocarcinoma. The characteristic features of MCNs are the lined mucinous epithelium with underlying ovarian-type stroma, but without communication with the ducts, while that for IPMNs are the communication with the ducts but without the underlying ovarian-type stroma. Here we report a case of MCN communicating with the main pancreatic duct in a 68-year-old woman. The initial radiographic diagnosis was pancreatic IPMN with main pancreatic involvement and this was also confirmed during gross examination. Histologically, the pancreatic cystic neoplasm was lined with mucinous epithelium with underlying ovarian-type of stroma. Immunohistochemical stains confirmed that the stroma cells were positive for ER, PR, alpha-inhibin and focally positive for CD10. The final pathologic diagnosis was pancreatic mucinous cystic neoplasm communicating with the main pancreatic duct. To the best of our knowledge, this is the second pathology confirmed case of MCN communicating with the main pancreatic duct. A careful gross examination and bivalvation of the main duct communicating with the cystic neoplasm helps render the correct diagnosis. If more cases are reported in the future, the MCN communicating with duct could become a new entity of pancreatic mucinous neoplasm. PMID- 29187490 TI - A Prospective Study of Intensity-modified Radiation Therapy in Comparison with Conventional 3D-RT for BR Pancreatic Cancer Patients with Arterial Involvement. AB - BACKGROUND/AIM: Intensity-modulated radiation therapy (IMRT) is a form of radiation therapy that allows accurate irradiation with reduced damage to surrounding tissues. Here, we analyzed borderline-resectable pancreatic cancer (BRPC) with arterial abutment (BR-A) patients with IMRT as neoadjuvant therapy and performed comparisons with patients with conventional RT to clarify the advantages of IMRT as a neoadjuvant therapy. PATIENTS AND METHODS: Thirty BR-A patients treated at our hospital between January 2012 and December 2015 were divided into two groups: 12 patients underwent conventional 3D-RT before resection (RT group); and 18 patients underwent IMRT before resection (IMRT group). We analyzed safety, tumor resection rate, histological classification of the tumor and overall survival. RESULTS: The R0 rate was 84% for the IMRT group and 83% for the RT group. Local therapeutic effects as assessed by Evans classification showed a higher local control rate in the IMRT group (Grade: 1, 0%; 2a, 25%; 2b, 41.6%; 3, 17%; 4, 8%) than in the RT group (Grade: 1, 17%; 2a, 50%; 2b, 17%; 3, 17%; 4, 0%). The cumulative dose of S1 treatment as adjuvant therapy was much smaller in the RT group (18.3%) compared to that in the IMRT group (57.1%, p=0.047), and with better subsequent overall survival rate (MST 32 months vs. 13.8 months, p=0.0273). CONCLUSION: The IMRT group showed a better control rate than the RT group. The neoadjuvant IMRT has advantages of higher completion rate of adjuvant chemotherapy with better nutritional status and better subsequent overall survival rate (OS). PMID- 29187492 TI - FOLFOX as First-line Therapy for Gastric Cancer with Severe Peritoneal Metastasis. AB - BACKGROUND/AIM: Severe peritoneal metastasis (PM) from advanced gastric cancer (AGC) causes massive ascites and inadequate oral intake. Because patients with severe PM are often not included in clinical trials, little is known regarding the efficacy and safety of oxaliplatin with l-leucovorin and bolus/continuous infusion of 5-fluorouracil (FOLFOX) for them. PATIENTS AND METHODS: We retrospectively studied AGC patients with massive ascites and/or inadequate oral intake due to severe PM treated with FOLFOX as the first-line treatment. RESULTS: Only 39 (10%) of 378 AGC patients had severe PM; 10 received FOLFOX. The median progression-free and overall survivals were 7.5 and 13.2 months, respectively. Ascites decreased in seven of nine patients with ascites, and oral intake improved in four of seven patients with an inadequate oral intake. Common grade 3 4 adverse events included neutropenia and anemia. CONCLUSION: This study suggests that FOLFOX is effective and manageable for AGC patients with severe PM. PMID- 29187491 TI - Incidence and Risk Factors of Symptomatic Hiatal Hernia Following Resection for Gastric and Esophageal Cancer. AB - BACKGROUND/AIM: Symptomatic hiatal hernia (HH) following resection for gastric or esophageal cancer is a potentially life-threatening event that may lead to emergent surgery. However, the incidence and risk factors of this complication remain unclear. PATIENTS AND METHODS: Data of patients who underwent resection for gastric or esophageal cancer between 2005 and 2012 were assessed and the incidence of symptomatic HH was evaluated. Factors associated with an increased risk for HH were investigated. RESULTS: Resection of gastric or esophageal cancer was performed in 471 patients. The primary tumor was located in the stomach, cardia and esophagus in 36%, 24%, and 40% of patients, respectively. The incidence of symptomatic HH was 2.8% (n=13). All patients underwent surgical hernia repair, 8 patients (61.5%) required emergent procedure, and 3 patients (23%) underwent bowel resection. Morbidity and mortality after HH repair was 38% and 8%, respectively. Factors associated with increased risk for symptomatic HH included Body-Mass-Index (median BMI with HH 27 (23-35) vs. BMI without HH 25 (15 51), p=0.043), diabetes (HH rate: with diabetes, 6.3% vs. without diabetes, 2%, p=0.034), tumor location (HH rate: stomach, 1.2% vs. esophagus, 1.1% vs. cardia, 7.9%, p=0.001), and resection type (HH rate: total/subtotal gastrectomy, 0.7% vs. transthoracic esophagectomy, 2.7% vs. extended gastrectomy, 6.1%, p=0.038). CONCLUSION: HH is a major adverse event after resection for gastric or esophageal cancer especially among patients undergoing extended gastrectomy for cardia cancer requiring a high rate of repeat surgery. Therefore, intensive follow-up examinations for high-risk patients and early diagnosis of asymptomatic patients are essential for selecting patients for elective surgery to avoid unpredictable emergent events with high morbidity and mortality. PMID- 29187493 TI - BRAF, NRAS and C-KIT Advanced Melanoma: Clinico-pathological Features, Targeted Therapy Strategies and Survival. AB - BACKGROUND/AIM: The mutational status of stage III and IV melanomas should be recognized in order to allow for targeted therapies. The aim of our study was the characterization of BRAF, NRAS and C-KIT melanoma patients, in order to define their optimal management. PATIENTS AND METHODS: Between 1991 and 2015, 63 mutated melanoma patients were treated and monitored during their diagnostic and therapeutic management at a single institution. RESULTS: BRAF-mutated melanoma patients were the most common, representing 70% of the study population, while NRAS- and C-KIT-mutated melanoma represented 19% and 11% respectively. BRAF mutated melanomas were mostly located at sites of intermittent sun exposure, and were associated with higher Breslow thickness and an increased number of mitosis. NRAS mutated melanoma were mainly observed in chronic sun-damaged areas and had a negative prognostic value, with shorter time to progression and a high incidence of central nervous system involvement. C-KIT mutated melanoma were located at acral and mucosal sites. Overall survival observed in the three groups of patients revealed wide differences. CONCLUSION: BRAF, NRAS and C-KIT melanomas constitute distinct clinico-pathological entities. BRAF-mutated melanoma benefit from both anti-BRAF and anti-MEK targeted therapies while triple-negative melanomas could benefit from novel anti-CTLA-4 and anti-PD-L1 immunotherapeutic approaches. PMID- 29187494 TI - Characterization of Prognostic Factors and the Efficacy of Adjuvant S-1 Chemotherapy in Patients with Post-surgery Extrahepatic Bile Duct Cancer. AB - BACKGROUND/AIM: There is no clear consensus on the type of adjuvant therapy that should be used for patients with extrahepatic bile duct cancer. PATIENTS AND METHODS: Two hundred and seventy-one patients that had undergone surgical resection for extrahepatic bile duct cancer composed the study cohort. Demographics, treatments, and relationships between the potential prognostic factors and survival rates were analyzed. RESULTS: The overall 3-year and 5-year survival rates for post-surgery extrahepatic bile duct cancer patients were 49.0% and 35.4%, respectively. Multivariate analysis revealed that regional lymph node metastasis was an independent negative prognostic factor. We observed a significant correlation between node-positive extrahepatic bile duct cancer and postoperative local recurrence, liver metastasis, peritoneal dissemination, and post-surgery lymph node metastasis. Adjuvant S-1 chemotherapy showed a favorable hazard ratio in patients with lymph node metastases or positive vascular invasion. CONCLUSION: We recommend the use of adjuvant S-1 therapy in patients with lymph node metastases or microvascular invasion. PMID- 29187495 TI - Outcome Evaluation of HER2 Breast Cancer Patients with Limited Brain Metastasis. AB - BACKGROUND/AIM: To appraise the outcome of limited brain metastasis (BMs) from HER2 breast cancer. PATIENTS AND METHODS: The study cohort included sixty-six patients Treatments consisted of surgery followed by radiotherapy (RT), or radiosurgery (SRS/HSRS) or whole brain radiotherapy (WBRT). RESULTS: Surgery followed by RT was performed in 25.8% of patients, SRS/HSRS alone in 48.5%, and WBRT alone in 25.7%. The median follow-up time was 23.4 months and 32.5 months for alive patients. Local recurrence occurred in 16 (24.2%) patients. The median, 1-, 2-, 3-year local control were (median not reached=nr), 87.5%, 71.2%, and 63.0%. The median 1-, 2-, 3-year overall survival were 30.7 months (95%CI: 18.9 42.6 months), 78.5%, 57.4%, 43.3%. Karnofsky Performance Scale (KPS), number of BMs, local treatment performed, the presence of extracranial (EC) metastases at the time of BMs diagnosis, and the administration of trastuzumab affected survival. CONCLUSION: HER2BC patients with good performance status, controlled EC disease and single BM had better outcome. In this long-term survivor patients, local BMs treatment can affect survival. PMID- 29187496 TI - Mucinous Cystic Neoplasms Lined by Abundant Mucinous Epithelium Frequently Involve KRAS Mutations and Malignant Progression. AB - BACKGROUND: Pancreatic and hepatic mucinous cyst neoplasms (MCNs) have a malignant potential, but indolent MCNs are not uncommon. MATERIALS AND METHODS: The pathological and genetic characteristics of resected MCNs (n=15) categorized by the amount of mucin of the lining epithelium were investigated. RESULTS: MCNs were divided into two groups: (i) a rich (r)-MCN group (n=6), in which more than half of the epithelium was lined by abundant mucinous epithelium; and (ii) a poor (p)-MCN group (n=9), which consisted of the remaining cases. Three patients in the r-MCN group showed invasive carcinoma or high-grade dysplasia, whereas all patients in the p-MCN group showed low-grade dysplasia. Mutations of Kirsten rat sarcoma viral oncogene homolog (KRAS) were more frequent in the r-MCN group (83%) (p-MCN; 11%, p<0.05). CONCLUSION: Mucinous MCNs more frequently have KRAS mutations and higher risk of malignant progression. PMID- 29187497 TI - A Glissonean Approach with Individual Isolation During Right Hemi-Hepatectomy After Portal Vein Embolization. AB - BACKGROUND/AIM: Although the Glissonean approach in hemi-hepatectomy is a very useful technique, right hemi-hepatectomy with Glissonean approach after portal vein embolization (PVE) is difficult because of the obstructing materials located at the right portal branch. The aim of this study was to evaluate the utility of the Glissonean approach with an individual isolation technique (GI technique) in right hemi-hepatectomies after PVE. PATIENTS AND METHODS: We retrospectively analyzed 21 patients who underwent the GI technique between March 2007 and June 2012. RESULTS: In one of the 21 patients, we could not perform the GI technique because of severe adhesions following previous operation; however, there were no troubles in the remaining 20 cases. In addition, none of the patients that were treated using this method developed massive ascites after right hemi-hepatectomy, despite 8 patients (40%) exhibiting severe fibrosis (F3 or F4). CONCLUSION: Even in right hemi-hepatectomy following PVE, our GI technique may be a useful procedures for patients. PMID- 29187498 TI - Association Between PD-L1 Expression and Metabolic Activity on 18F-FDG PET/CT in Patients with Small-sized Lung Cancer. AB - AIM: We evaluated the metabolic characteristics of small-sized lung cancer using 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG PET/CT) with regard to programmed cell death ligand 1 (PD-L1) expression. MATERIALS AND METHODS: PD-L1 expression was evaluated by immunohistochemistry with the antibody clone SP142 in 263 patients with surgically resected primary small-sized lung cancer. Specimens with <5% tumor membrane staining were considered negative. We examined the association between the frequency of PD-L1 expression and the maximum standardized uptake value (SUVmax) in preoperative 18F FDG PET/CT. RESULTS: Among patients with non-small cell lung cancer (NSCLC), the SUVmax was significantly higher in those with PD-L1 expression than in those without (p<0.0001). However, there was no correlation between SUVmax and PD-L1 expression in patients with neuroendocrine tumors (p=0.9638). Multivariate analysis revealed that smoking and a high SUVmax were independent predictors of PD-L1 expression. CONCLUSION: PD-L1 expression was related to high glucose metabolism in small-sized NSCLC. PMID- 29187499 TI - Anastomotic Leakage Using Linear Stapling Device with Pre-attached Bioabsorbable Polyglycolic Acid Felt After Laparoscopic Anterior Resection. AB - AIM: Many studies have evaluated the risk factors for anastomotic leakage after laparoscopic anterior resection. In this study in order to increase the tightness of anastomoses and prevent bleeding from their staple lines, a linear stapler with pre-attached bioabsorbable polyglycolic acid (PGA) felt was used for rectal transection, and the short-term surgical outcomes were evaluated. PATIENTS AND METHODS: A prospective registry of 62 patients with rectosigmoidal or rectal carcinoma who initially underwent laparoscopic anterior resection using PGA felt for rectal transection was reviewed. RESULTS: The overall frequency of anastomotic leakage was 1.6% (1/62), and none of the patients developed postoperative staple line bleeding or other adverse events related to the use of PGA felt. CONCLUSION: The frequency of anastomotic leakage was relatively low, and therefore the use of a linear stapler with pre-attached bioabsorbable PGA felt might reduce the risk of adverse events related to anastomosis, especially anastomotic leakage. PMID- 29187500 TI - Robotic-assisted Transperitoneal Infrarenal Para-aortic Lymphadenectomy for Gynecological Malignancies: Comparison with a Laparoscopic Approach. AB - BACKGROUND/AIM: We evaluated the clinical feasibility and surgical outcomes of robotic-assisted transperitoneal infrarenal para-aortic lymphadenectomy (TIPAL) in patients with gynecological malignancies. PATIENTS AND METHODS: The perioperative outcomes in 90 patients with gynecological malignancies who underwent laparoscopic (n=43) or robotic-assisted (n=47) TIPAL were compared retrospectively. RESULTS: The operative time for pelvic and total lymphadenectomy were significantly shorter in the robotic-assisted approach, whereas the time for infrarenal para-aortic lymphadenectomy did not differ statistically. In contrast, the number of infrarenal para-aortic lymph nodes was significantly higher in the robotic-assisted approach. We compared the time per retrieved lymph node in both approaches, and those for pelvic, infrarenal para-aortic, and total lymphadenectomy were significantly shorter in the robotic-assisted approach. CONCLUSION: In our study, the robotic-assisted TIPAL took less time to retrieve a lymph node than the laparoscopic approach. The robotic-assisted approach for TIPAL is feasible for the staging and treatment of patients with gynecological malignancies. PMID- 29187501 TI - Irinotecan and Oxaliplatin Might Provide Equal Benefit as Adjuvant Chemotherapy for Patients with Resectable Synchronous Colon Cancer and Liver-confined Metastases: A Nationwide Database Study. AB - BACKGROUND: Although irinotecan and oxaliplatin are both standard treatments for advanced colon cancer, it remains unknown whether either is effective for patients with resectable synchronous colon cancer and liver-confined metastasis (SCCLM) after curative surgery. PATIENTS AND METHODS: A population-based cohort of patients diagnosed with de novo SCCLM between 2004 and 2009 was established by searching the database of the Taiwan Cancer Registry and the National Health Insurance Research Database of Taiwan. Patients who underwent curative surgery as their first therapy followed by chemotherapy doublets were classified into the irinotecan group or oxaliplatin group accordingly. Patients who received radiotherapy or did not receive chemotherapy doublets were excluded. RESULTS: We included 6,533 patients with de novo stage IV colon cancer. Three hundred and nine of them received chemotherapy doublets after surgery; 77 patients received irinotecan and 232 patients received oxaliplatin as adjuvant chemotherapy. The patients in both groups exhibited similar overall survival (median: not reached vs. 40.8 months, p=0.151) and time to the next line of treatment (median: 16.5 vs. 14.3 months, p=0.349) in both univariate and multivariate analyses. Additionally, patients with resectable SCCLM had significantly shorter median overall survival than patients with stage III colon cancer who underwent curative surgery and subsequent adjuvant chemotherapy, but longer median overall survival than patients with de novo stage IV colon cancer who underwent surgery only at the primary site followed by standard systemic chemotherapy (p<0.001). CONCLUSION: Irinotecan and oxaliplatin exhibited similar efficacy in patients who underwent curative surgery for resectable SCCLM. PMID- 29187502 TI - Errata. PMID- 29187504 TI - Tissue-Specific Gene Inactivation in Xenopus laevis: Knockout of lhx1 in the Kidney with CRISPR/Cas9. AB - Studying genes involved in organogenesis is often difficult because many of these genes are also essential for early development. The allotetraploid frog, Xenopus laevis, is commonly used to study developmental processes, but because of the presence of two homeologs for many genes, it has been difficult to use as a genetic model. Few studies have successfully used CRISPR in amphibians, and currently there is no tissue-targeted knockout strategy described in Xenopus The goal of this study is to determine whether CRISPR/Cas9-mediated gene knockout can be targeted to the Xenopus kidney without perturbing essential early gene function. We demonstrate that targeting CRISPR gene editing to the kidney and the eye of F0 embryos is feasible. Our study shows that knockout of both homeologs of lhx1 results in the disruption of kidney development and function but does not lead to early developmental defects. Therefore, targeting of CRISPR to the kidney may not be necessary to bypass the early developmental defects reported upon disruption of Lhx1 protein expression or function by morpholinos, antisense RNA, or dominant negative constructs. We also establish a control for CRISPR in Xenopus by editing a gene (slc45a2) that when knocked out results in albinism without altering kidney development. This study establishes the feasibility of tissue-specific gene knockout in Xenopus, providing a cost-effective and efficient method for assessing the roles of genes implicated in developmental abnormalities that is amenable to high-throughput gene or drug screening techniques. PMID- 29187505 TI - A Common Pathway of Root Growth Control and Response to CLE Peptides Through Two Receptor Kinases in Arabidopsis. AB - Cell-cell communication is essential for plants to integrate developmental programs with external cues that affect their growth. Recent advances in plant signaling have uncovered similar molecular mechanisms in shoot, root, and vascular meristem signaling that involve receptor-like kinases and small, secreted peptides. Here, we report that the receptor-like kinases TOAD2/RPK2 and RPK1 regulate root growth by controlling cell proliferation and affecting meristem size. Two types of developmental alterations were observed upon exogenous CLE peptide application. The first type was detected in all plants treated, and comprise increased proliferative activity of cells in the stem cell niche and a delay of progression in differentiation of daughter cells. The second type was changes specific to the genotypes that are sensitive to CLE-driven root meristem inhibition and include a large decrease in the occurrence of cell divisions in longitudinal files, correlating with shorter meristems and cessation of root growth. The root meristems of toad2/rpk2 mutant plants are insensitive to the inhibitory effect of CLE17 peptide treatment, consistent with TOAD2/RPK2 function as a receptor for CLE peptides. In addition, a strong reduction in the expression of RPK1 protein upon CLE treatment, dependent on TOAD2/RPK2, suggests that these two RLKs mediate CLE signaling in a common pathway to control root growth. PMID- 29187506 TI - Cooperative Control of Ecdysone Biosynthesis in Drosophila by Transcription Factors Seance, Ouija Board, and Molting Defective. AB - Ecdysteroids are steroid hormones that control many aspects of development and physiology. During larval development, ecdysone is synthesized in an endocrine organ called the prothoracic gland through a series of ecdysteroidogenic enzymes encoded by the Halloween genes. The expression of the Halloween genes is highly restricted and dynamic, indicating that their spatiotemporal regulation is mediated by their tight transcriptional control. In this study, we report that three zinc finger-associated domain (ZAD)-C2H2 zinc finger transcription factors Seance (Sean), Ouija board (Ouib), and Molting defective (Mld)-cooperatively control ecdysone biosynthesis in the fruit fly Drosophila melanogaster Sean and Ouib act in cooperation with Mld to positively regulate the transcription of neverland and spookier, respectively, two Halloween genes. Remarkably, loss-of function mutations in sean, ouib, or mld can be rescued by the expression of neverland, spookier, or both, respectively. These results suggest that the three transcription factors have distinct roles in coordinating the expression of just two genes in Drosophila Given that neverland and spookier are located in constitutive heterochromatin, Sean, Ouib, and Mld represent the first example of a transcription factor subset that regulates genes located in constitutive heterochromatin. PMID- 29187507 TI - Using Separation-of-Function Mutagenesis To Define the Full Spectrum of Activities Performed by the Est1 Telomerase Subunit in Vivo. AB - A leading objective in biology is to identify the complete set of activities that each gene performs in vivo In this study, we have asked whether a genetic approach can provide an efficient means of achieving this goal, through the identification and analysis of a comprehensive set of separation-of-function (sof ) mutations in a gene. Toward this goal, we have subjected the Saccharomyces cerevisiae EST1 gene, which encodes a regulatory subunit of telomerase, to intensive mutagenesis (with an average coverage of one mutation for every 4.5 residues), using strategies that eliminated those mutations that disrupted protein folding/stability. The resulting set of sof- mutations defined four biochemically distinct activities for the Est1 telomerase protein: two temporally separable steps in telomerase holoenzyme assembly, a telomerase recruitment activity, and a fourth newly discovered regulatory function. Although biochemically distinct, impairment of each of these four different activities nevertheless conferred a common phenotype (critically short telomeres) comparable to that of an est1-? null strain. This highlights the limitations of gene deletions, even for nonessential genes; we suggest that employing a representative set of sof- mutations for each gene in future high- and low throughput investigations will provide deeper insights into how proteins interact inside the cell. PMID- 29187509 TI - The spectrum, incidence, kinetics and management of endocrinopathies with immune checkpoint inhibitors for metastatic melanoma. AB - OBJECTIVE: Endocrine immune-related adverse events (endocrinopathies) are increasingly prevalent with the use of immune checkpoint inhibitors for the treatment of metastatic melanoma and other malignancies. There are no evidence based guidelines for the screening or management of such patients. To describe the spectrum, incidence, kinetics and management of endocrinopathies with immune checkpoint inhibitors. DESIGN: A prospective study conducted at Melanoma Institute Australia between April 2014 and October 2015. METHODS: A total of 177 patients were treated with (a) ipilimumab (n = 15), (b) anti-PD-1 (nivolumab, pembrolizumab) (n = 103) or (c) combination ipilimumab and anti-PD-1 (n = 59) and were screened and managed for the subsequent endocrinopathies. The main outcome measures were the incidence and kinetics of endocrinopathy by immunotherapy drug class. RESULTS: Thirty-one patients (18%) developed an endocrine immune-related adverse event (thyroid dysfunction: 14%, hypophysitis: 6% and autoimmune diabetes: 0.6%). Combination immunotherapy was more likely to result in a single or multiple endocrinopathy compared to anti-PD-1 monotherapy (27% vs 9% and 7% vs 0% respectively, P < 0.01). Endocrinopathies occurred after a median of 8 weeks from treatment commencement (range: 12-225 days), with combination immunotherapy resulting in significantly earlier onset compared to ipilimumab (median: 30 vs 76 days, P = 0.046). The majority of endocrinopathies were identified in asymptomatic patients with hormonal screening. There were no baseline predictors for endocrinopathy. CONCLUSIONS: Combination immunotherapy has a greater risk of development of endocrinopathy compared to anti-PD-1 monotherapy. Regular biochemical profiling of patients, particularly within the first twelve weeks, results in early detection of endocrinopathy to minimise morbidity. PMID- 29187508 TI - Relaxed Selection During a Recent Human Expansion. AB - Humans have colonized the planet through a series of range expansions, which deeply impacted genetic diversity in newly settled areas and potentially increased the frequency of deleterious mutations on expanding wave fronts. To test this prediction, we studied the genomic diversity of French Canadians who colonized Quebec in the 17th century. We used historical information and records from ~4000 ascending genealogies to select individuals whose ancestors lived mostly on the colonizing wave front and individuals whose ancestors remained in the core of the settlement. Comparison of exomic diversity reveals that: (i) both new and low-frequency variants are significantly more deleterious in front than in core individuals, (ii) equally deleterious mutations are at higher frequencies in front individuals, and (iii) front individuals are two times more likely to be homozygous for rare very deleterious mutations present in Europeans. These differences have emerged in the past six to nine generations and cannot be explained by differential inbreeding, but are consistent with relaxed selection mainly due to higher rates of genetic drift on the wave front. Demographic inference and modeling of the evolution of rare variants suggest lower effective size on the front, and lead to an estimation of selection coefficients that increase with conservation scores. Even though range expansions have had a relatively limited impact on the overall fitness of French Canadians, they could explain the higher prevalence of recessive genetic diseases in recently settled regions of Quebec. PMID- 29187510 TI - ERCC1 as predictive biomarker to platinum-based chemotherapy in adrenocortical carcinomas. AB - OBJECTIVE: Platinum-based chemotherapy (PBC) is the most effective cytotoxic treatment for advanced adrenocortical carcinoma (ACC). Excision repair cross complementing group 1 (ERCC1) plays a critical role in the repair of platinum induced DNA damage. Two studies investigating the role of ERCC1 immunostaining as a predictive marker for the response to PBC in ACC had reported conflicting results. Both studies used the ERCC1-antibody clone 8F1 that later turned out to be not specific. The aim of this study was to evaluate the predictive role of ERCC1 with a new specific antibody in a larger series of ACC. DESIGN AND METHODS: 146 ACC patients with available FFPE slides were investigated. All patients underwent PBC (median cycles = 6), including cisplatin (n = 131) or carboplatin (n = 15), in most cases combined with etoposide (n = 144), doxorubicin (n = 131) and mitotane (n = 131). Immunostaining was performed with the novel ERCC1 antibody clone 4F9. The relationship between ERCC1 expression and clinicopathological parameters, as well as best objective response to therapy and progression-free survival (PFS) during PBC was evaluated. RESULTS: High ERCC1 expression was observed in 66% of ACC samples. During PBC, 43 patients experienced objective response (29.5%), 49 stable disease (33.6%), 8 mixed response (5.5%) and 46 progressive disease (31.5%) without any relationship with the ERCC1 immunostaining. No significant correlation was also found between ERCC1 expression and progression-free survival (median 6.5 vs 6 months, P = 0.33, HR = 1.23, 95% CI = 0.82-2.0). CONCLUSION: ERCC1 expression is not directly associated with sensitivity to PBC in ACC. Thus, other predictive biomarkers are required to support treatment decisions in patients with ACC. PMID- 29187511 TI - Pregnancy outcomes are not altered by variation in thyroid function within the normal range in women free of thyroid disease. AB - OBJECTIVE: In the recently revised guidelines on the management of thyroid dysfunction during pregnancy, treatment with thyroid hormone (LT4) is not recommended in women without thyroid autoimmunity (TAI) and TSH levels in the range 2.5-4.0 mIU/L, and in a recent study in that particular group of pregnant women, more complications were observed when a treatment with LT4 was given. The objective of the study was therefore to investigate whether variation in thyroid function within the normal (non-pregnant) range in women free of thyroid disease was associated with altered pregnancy outcomes? DESIGN: Cross-sectional data analysis of 1321 pregnant women nested within an ongoing prospective collection of pregnant women's data in a single centre in Brussels, Belgium. METHODS: Thyroid peroxidase antibodies (TPO-abs), thyroid-stimulating hormone (TSH), free T4 (FT4) and ferritin levels were measured and baseline characteristics were recorded. Women taking LT4, with TAI and thyroid function outside the normal non pregnant range were excluded. Pregnancy outcomes and baseline characteristics were correlated with all TSH and FT4 levels within the normal range and compared between two groups (TSH cut-off < and >=2.5 mIU/L). RESULTS: Tobacco use was associated with higher serum TSH levels (OR: 1.38; CI 95%: 1.08-1.74); P = 0.009. FT4 levels were inversely correlated with age and BMI (rho = -0.096 and -0.089; P < 0.001 and 0.001 respectively) and positively correlated with ferritin levels (rho = 0.097; P < 0.001). Postpartum haemorrhage (>500 mL) was inversely associated with serum FT4 levels (OR: 0.35; CI 95%: 0.13-0.96); P = 0.040. Also 10% of women free of thyroid disease had serum TSH levels >=2.5 mIU/L. CONCLUSIONS: Variation in thyroid function during the first trimester within the normal (non-pregnant) range in women free of thyroid disease was not associated with altered pregnancy outcomes. These results add evidence to the recommendation against LT4 treatment in pregnant women with high normal TSH levels and without TPO antibodies. PMID- 29187513 TI - A critical evaluation of the anabolic response after bolus or continuous feeding in COPD and healthy older adults. AB - After bolus and continuous enteral feeding of the same protein, different digestion and absorption kinetics and anabolic responses are observed. Establishing which mode of feeding has the highest anabolic potential in patients with chronic obstructive pulmonary disease (COPD) may aid in the prevention of muscle wasting, but an important confounding factor is the duration of assessments after bolus feeding. We hypothesized that the anabolic response to bolus and continuous feeding in COPD patients is comparable when methodological issues are addressed. Twenty-one older adults (12 patients with stage II-IV COPD and 9 healthy controls) were studied after intake of a fast-absorbing hydrolyzed casein protein-carbohydrate mixture either as a single bolus or as small sips (crossover design). Whole body protein synthesis (PS), breakdown (PB), net PS (PS - PB) protein efficiency (netPSPE), net protein balance (phenylalanine (PHE) intake - PHE hydroxylation) protein efficiency (netBalPE), and splanchnic PHE extraction (SPEPHE) were assessed using stable isotope tracer methodology. Bolus feeding assessments were done at 90, 95, and 99% of the calculated duration of the anabolic response. At 99%, netBalPE was higher for sip feeding than bolus feeding in both groups (P<0.0001). Nevertheless, bolus feeding was associated with a lower SPEPHE (P<0.0001) and higher netPSPE (P<0.0001). At 90% compared with 99%, PS and netBalPE after bolus feeding was significantly overestimated. In conclusion, several factors complicate a comparison of the anabolic capacity of bolus and continuous feeding in acute studies, including the critical role of SPE calculation and assumptions, and the duration of postprandial assessments after bolus feeding. PMID- 29187512 TI - Familial multinodular goiter and Sertoli-Leydig cell tumors associated with a large intragenic in-frame DICER1 deletion. AB - OBJECTIVE: Familial multinodular goiter (MNG), with or without ovarian Sertoli Leydig cell tumor (SLCT), has been linked to DICER1 syndrome. We aimed to search for the presence of a germline DICER1 mutation in a large family with a remarkable history of MNG and SLCT, and to further explore the relevance of the identified mutation. DESIGN AND METHODS: Sanger sequencing, Fluidigm Access Array and multiplex ligation-dependent probe amplification (MLPA) techniques were used to screen for DICER1 mutations in germline DNA from 16 family members. Where available, tumor DNA was also studied. mRNA and protein extracted from carriers' lymphocytes were used to characterize the expression of the mutant DICER1. RESULTS: Nine of 16 tested individuals carried a germline, in-frame DICER1 deletion (c.4207-41_5364+1034del), which resulted in the loss of exons 23 and 24 from the cDNA. The mutant transcript does not undergo nonsense-mediated decay and the protein is devoid of specific metal ion-binding amino acids (p.E1705 and p.D1709) in the RNase IIIb domain. In addition, characteristic somatic 'second hit' mutations in this region were found on the other allele in tumors. CONCLUSIONS: Patients with DICER1 syndrome usually present a combination of a typically truncating germline DICER1 mutation and a tumor-specific hotspot missense mutation within the sequence encoding the RNase IIIb domain. The in frame deletion found in this family suggests that the germline absence of p.E1705 and p.D1709, which are crucial for RNase IIIb activity, may be enough to permit DICER1 syndrome to occur.

PMID- 29187516 TI - Amyloid-Like beta-Aggregates as Force-Sensitive Switches in Fungal Biofilms and Infections. AB - Cellular aggregation is an essential step in the formation of biofilms, which promote fungal survival and persistence in hosts. In many of the known yeast cell adhesion proteins, there are amino acid sequences predicted to form amyloid-like beta-aggregates. These sequences mediate amyloid formation in vitro. In vivo, these sequences mediate a phase transition from a disordered state to a partially ordered state to create patches of adhesins on the cell surface. These beta aggregated protein patches are called adhesin nanodomains, and their presence greatly increases and strengthens cell-cell interactions in fungal cell aggregation. Nanodomain formation is slow (with molecular response in minutes and the consequences being evident for hours), and strong interactions lead to enhanced biofilm formation. Unique among functional amyloids, fungal adhesin beta aggregation can be triggered by the application of physical shear force, leading to cellular responses to flow-induced stress and the formation of robust biofilms that persist under flow. Bioinformatics analysis suggests that this phenomenon may be widespread. Analysis of fungal abscesses shows the presence of surface amyloids in situ, a finding which supports the idea that phase changes to an amyloid-like state occur in vivo. The amyloid-coated fungi bind the damage associated molecular pattern receptor serum amyloid P component, and there may be a consequential modulation of innate immune responses to the fungi. Structural data now suggest mechanisms for the force-mediated induction of the phase change. We summarize and discuss evidence that the sequences function as triggers for protein aggregation and subsequent cellular aggregation, both in vitro and in vivo. PMID- 29187518 TI - Neurofascin antibodies in autoimmune, genetic, and idiopathic neuropathies. AB - OBJECTIVE: To measure the frequency, persistence, isoform specificity, and clinical correlates of neurofascin antibodies in patients with peripheral neuropathies. METHODS: We studied cohorts of patients with Guillain-Barre syndrome (GBS) or chronic inflammatory demyelinating polyneuropathy (CIDP) (n = 59), genetic neuropathy (n = 111), and idiopathic neuropathy (n = 43) for immunoglobulin (Ig) G and IgM responses to 3 neurofascin (NF) isoforms (NF140, NF155, and NF186) using cell-based assays. RESULTS: Neurofascin antibodies were more common in patients with GBS/CIDP (14%, 8 of 59) compared to genetic neuropathy controls (3%, 3 of 111, p = 0.01). Seven percent (3 of 43) of patients with idiopathic neuropathy also had neurofascin antibodies. NF155 IgG4 antibodies were associated with CIDP refractory to IV immunoglobulin but responsive to rituximab, and some of these patients had an acute onset resembling GBS. NF186 IgG and IgM to either isoform were less specific. A severe form of CIDP, approaching a locked-in state, was seen in a patient with antibodies recognizing all 3 neurofascin isoforms. CONCLUSIONS: Neurofascin antibodies were 4 times more frequent in autoimmune neuropathy samples compared to genetic neuropathy controls. Persistent IgG4 responses to NF155 correlated with severe CIDP resistant to usual treatments but responsive to rituximab. IgG4 antibodies against the common domains shared by glial and axonal isoforms may portend a particularly severe but treatable neuropathy. The prognostic implications of neurofascin antibodies in a subset of idiopathic neuropathy patients and transient IgM responses in GBS require further investigation. PMID- 29187515 TI - Nrf2 at the heart of oxidative stress and cardiac protection. AB - The NFE2L2 gene encodes the transcription factor Nrf2 best known for regulating the expression of antioxidant and detoxification genes. Gene knockout approaches have demonstrated its universal cytoprotective features. While Nrf2 has been the topic of intensive research in cancer biology since its discovery in 1994, understanding the role of Nrf2 in cardiovascular disease has just begun. The literature concerning Nrf2 in experimental models of atherosclerosis, ischemia, reperfusion, cardiac hypertrophy, heart failure, and diabetes supports its cardiac protective character. In addition to antioxidant and detoxification genes, Nrf2 has been found to regulate genes participating in cell signaling, transcription, anabolic metabolism, autophagy, cell proliferation, extracellular matrix remodeling, and organ development, suggesting that Nrf2 governs damage resistance as well as wound repair and tissue remodeling. A long list of small molecules, most derived from natural products, have been characterized as Nrf2 inducers. These compounds disrupt Keap1-mediated Nrf2 ubquitination, thereby prohibiting proteasomal degradation and allowing Nrf2 protein to accumulate and translocate to the nucleus, where Nrf2 interacts with sMaf to bind to ARE in the promoter of genes. Recently alternative mechanisms driving Nrf2 protein increase have been revealed, including removal of Keap1 by autophagy due to p62/SQSTM1 binding, inhibition of betaTrCP or Synoviolin/Hrd1-mediated ubiquitination of Nrf2, and de novo Nrf2 protein translation. We review here a large volume of literature reporting historical and recent discoveries about the function and regulation of Nrf2 gene. Multiple lines of evidence presented here support the potential of dialing up the Nrf2 pathway for cardiac protection in the clinic. PMID- 29187520 TI - Investigation of specific interactions between T7 promoter and T7 RNA polymerase by force spectroscopy using atomic force microscope. AB - The specific recognition and binding of promoter and RNA polymerase is the first step of transcription initiation in bacteria and largely determines transcription activity. Therefore, direct analysis of the interaction between promoter and RNA polymerase in vitro may be a new strategy for promoter characterization, to avoid interference due to the cell's biophysical condition and other regulatory elements. In the present study, the specific interaction between T7 promoter and T7 RNA polymerase was studied as a model system using force spectroscopy based on atomic force microscope (AFM). The specific interaction between T7 promoter and T7 RNA polymerase was verified by control experiments, and the rupture force in this system was measured as 307.2 +/- 6.7 pN. The binding between T7 promoter mutants with various promoter activities and T7 RNA polymerase was analyzed. Interaction information including rupture force, rupture distance and binding percentage were obtained in vitro, and reporter gene expression regulated by these promoters was also measured according to a traditional promoter activity characterization method in vivo Using correlation analysis, it was found that the promoter strength characterized by reporter gene expression was closely correlated with rupture force and the binding percentage by force spectroscopy. These results indicated that the analysis of the interaction between promoter and RNA polymerase using AFM-based force spectroscopy was an effective and valid approach for the quantitative characterization of promoters. PMID- 29187519 TI - Proteomics Reveals the Molecular Underpinnings of Stronger Learning and Memory in Eastern Compared to Western Bees. AB - The eastern (Apis cerana cerana, Acc) and western (Apis mellifera ligustica, Aml) honeybee are two major honeybee species. Surprisingly, little is known about the fundamental molecular neurobiology of brain suborgans of Acc and Aml. We characterized and compared the proteomes of mushroom bodies (MBs), antennal lobes (ALs) and optical lobes (OLs) in the brain of both species, and biologically validated the functions related to learning and memory. Acc and Aml have evolved similar proteome signatures in MBs and OLs to drive the domain-specific neural activities. In MBs of both species, commonly enriched and enhanced functional groups related to protein metabolism and Ca2+ transport relative to ALs and OLs, suggests that proteins and Ca2+ are vital for consolidating learning and memory via modulation of synaptic structure and signal transduction. Furthermore, in OLs of both species, the mainly enriched ribonucleoside metabolism suggests its vital role as second messenger in promoting phototransduction. Notably, in ALs of both species, distinct proteome settings have shaped to prime olfactory learning and memory. In ALs of Acc, this is supported by the enriched cytoskeleton organization to sustain olfactory signaling through modulation of plasticity in glomeruli and intracellular transport. In ALs of Aml, however, the enriched functional groups implicated in hydrogen ion transport are indicative of their importance in supporting olfactory processes by regulation of synaptic transmission. The biological confirmation of enhanced activities of protein metabolism and signal transduction in ALs and MBs of Acc relative to in Aml demonstrates that a stronger sense of olfactory learning and memory has evolved in Acc. The reported first in-depth proteome data of honeybee brain suborgans provide a novel insight into the molecular basis of neurobiology, and is potentially useful for further neurological studies in honeybees and other insects. PMID- 29187521 TI - Plant DHDPR forms a dimer with unique secondary structure features that preclude higher-order assembly. AB - Dihydrodipicolinate reductase (DHDPR) catalyses the second reaction in the diaminopimelate pathway of lysine biosynthesis in bacteria and plants. In contrast with the tetrameric bacterial DHDPR enzymes, we show that DHDPR from Vitis vinifera (grape) and Selaginella moellendorffii are dimeric in solution. In the present study, we have also determined the crystal structures of DHDPR enzymes from the plants Arabidopsis thaliana and S. moellendorffii, which are the first dimeric DHDPR structures. The analysis of these models demonstrates that the dimer forms through the intra-strand interface, and that unique secondary features in the plant enzymes block tetramer assembly. In addition, we have also solved the structure of tetrameric DHDPR from the pathogenic bacteria Neisseria meningitidis Measuring the activity of plant DHDPR enzymes showed that they are much more prone to substrate inhibition than the bacterial enzymes, which appears to be a consequence of increased flexibility of the substrate-binding loop and higher affinity for the nucleotide substrate. This higher propensity to substrate inhibition may have consequences for ongoing efforts to increase lysine biosynthesis in plants. PMID- 29187522 TI - Surgical academic reach: the higher degree effect quantified. AB - INTRODUCTION: Proof of professional specific academic attainment is embedded within the Joint Committee on Surgical Training 2013 general surgery curriculum, mandating that all higher general surgical trainees (HST) obtain three peer reviewed publications to qualify for Certification of Completion of Training. Yet, Modernising Medical Careers (MMC) has been associated with a trend away from the gold standard postgraduate credentials of higher degrees by research. This study aimed to evaluate the academic achievements of a post-MMC UK Deanery HST cohort to determine what additional benefits higher degree study might confer. METHOD: The Scopus bibliographic database (Elsevier, RELX Group) was used to characterise the academic profiles of 101 consecutive HSTs and supplemented with Intercollegiate Surgical Programme Curriculum data. Primary outcome measures were numbers of publications, citations and Hirsch indices (HI). RESULTS: Thirty-seven HSTs (36.6%) had been awarded higher degrees (29 Doctor of Medicine, 8 Doctor of Philosophy). Academic profiles of HSTs with higher degrees were stronger than those of HSTs without, specifically: median (range) publication numbers 16 (2-57) vs 2 (0-11, P<0.001), citations 93 (0-1600) vs 6 (0-132, P<0.001), first author publications 6 (0-33) vs 3 (0-106, P<0.001), communications to learnt societies 30 (5-79) vs 8 (2-35, P<0.001) and HI 6 (1-26) vs 1 (0-6, P<0.001). CONCLUSION: Proof of academic reach by higher degree was associated with important enhanced professional credentials, strengthening HIs sixfold. Trainers and trainees alike should be aware of the relative magnitude of such benefits when planning educational programmes. PMID- 29187523 TI - Modeling hypercholesterolemia and vascular lipid accumulation in LDL receptor mutant zebrafish. AB - Elevated plasma LDL cholesterol is the dominant risk factor for the development of atherosclerosis and cardiovascular disease. Deficiency in the LDL receptor (LDLR) is a major cause of familial hypercholesterolemia in humans, and the LDLR knockout mouse is a major animal model of atherosclerosis. Here we report the generation and characterization of an ldlr mutant zebrafish as a new animal model to study hypercholesterolemia and vascular lipid accumulation, an early event in the development of human atherosclerosis. The ldlr mutant zebrafish were characterized by activated SREBP-2 pathway and developed moderate hypercholesterolemia when fed a normal diet. However, a short-term, 5-day feeding of ldlr mutant larvae with a high-cholesterol diet (HCD) resulted in exacerbated hypercholesterolemia and accumulation of vascular lipid deposits. Lomitapide, an inhibitor of apoB lipoprotein secretion, but not the antioxidant probucol, significantly reduced accumulation of vascular lipid deposits in HCD-fed ldlr mutant larvae. Furthermore, ldlr mutants were defective in hepatic clearance of lipopolysaccharides, resulting in reduced survival. Taken together, our data suggest that the ldlr knockout zebra-fish is a versatile model for studying the function of the LDL receptor, hypercholesterolemia, and related vascular pathology in the context of early atherosclerosis. PMID- 29187524 TI - dTBC1D7 regulates systemic growth independently of TSC through insulin signaling. AB - The insulin signaling pathway plays key roles in systemic growth. TBC1D7 has recently been identified as the third subunit of the tuberous sclerosis complex (TSC), a negative regulator of cell growth. Here, we used Drosophila as a model system to dissect the physiological function of TBC1D7 in vivo. In mutants lacking TBC1D7, cell and organ growth were promoted, and TBC1D7 limited cell growth in a cell-nonautonomous and TSC-independent manner. TBC1D7 is specifically expressed in insulin-producing cells in the fly brain and regulated biosynthesis and release of insulin-like peptide 2, leading to systemic growth. Furthermore, animals carrying the dTBC1D7 mutation were hypoglycemic, short-lived, and sensitive to oxidative stress. Our findings provide new insights into the physiological function of TBC1D7 in the systemic control of growth, as well as insights into human disorders caused by TBC1D7 mutation. PMID- 29187525 TI - Humanin is an endogenous activator of chaperone-mediated autophagy. AB - Chaperone-mediated autophagy (CMA) serves as quality control during stress conditions through selective degradation of cytosolic proteins in lysosomes. Humanin (HN) is a mitochondria-associated peptide that offers cytoprotective, cardioprotective, and neuroprotective effects in vivo and in vitro. In this study, we demonstrate that HN directly activates CMA by increasing substrate binding and translocation into lysosomes. The potent HN analogue HNG protects from stressor-induced cell death in fibroblasts, cardiomyoblasts, neuronal cells, and primary cardiomyocytes. The protective effects are lost in CMA-deficient cells, suggesting that they are mediated through the activation of CMA. We identified that a fraction of endogenous HN is present at the cytosolic side of the lysosomal membrane, where it interacts with heat shock protein 90 (HSP90) and stabilizes binding of this chaperone to CMA substrates as they bind to the membrane. Inhibition of HSP90 blocks the effect of HNG on substrate translocation and abolishes the cytoprotective effects. Our study provides a novel mechanism by which HN exerts its cardioprotective and neuroprotective effects. PMID- 29187526 TI - Aurora A kinase phosphorylates Hec1 to regulate metaphase kinetochore-microtubule dynamics. AB - Precise regulation of kinetochore-microtubule attachments is essential for successful chromosome segregation. Central to this regulation is Aurora B kinase, which phosphorylates kinetochore substrates to promote microtubule turnover. A critical target of Aurora B is the N-terminal "tail" domain of Hec1, which is a component of the NDC80 complex, a force-transducing link between kinetochores and microtubules. Although Aurora B is regarded as the "master regulator" of kinetochore-microtubule attachment, other mitotic kinases likely contribute to Hec1 phosphorylation. In this study, we demonstrate that Aurora A kinase regulates kinetochore-microtubule dynamics of metaphase chromosomes, and we identify Hec1 S69, a previously uncharacterized phosphorylation target site in the Hec1 tail, as a critical Aurora A substrate for this regulation. Additionally, we demonstrate that Aurora A kinase associates with inner centromere protein (INCENP) during mitosis and that INCENP is competent to drive accumulation of the kinase to the centromere region of mitotic chromosomes. These findings reveal that both Aurora A and B contribute to kinetochore-microtubule attachment dynamics, and they uncover an unexpected role for Aurora A in late mitosis. PMID- 29187527 TI - Identification of seipin-linked factors that act as determinants of a lipid droplet subpopulation. AB - Functional heterogeneity within the lipid droplet (LD) pool of a single cell has been observed, yet the underlying mechanisms remain enigmatic. Here, we report on identification of a specialized LD subpopulation characterized by a unique proteome and a defined geographical location at the nucleus-vacuole junction contact site. In search for factors determining identity of these LDs, we screened ~6,000 yeast mutants for loss of targeting of the subpopulation marker Pdr16 and identified Ldo45 (LD organization protein of 45 kD) as a crucial targeting determinant. Ldo45 is the product of a splicing event connecting two adjacent genes (YMR147W and YMR148W/OSW5/LDO16). We show that Ldo proteins cooperate with the LD biogenesis component seipin and establish LD identity by defining positioning and surface-protein composition. Our studies suggest a mechanism to establish functional differentiation of organelles, opening the door to better understanding of metabolic decisions in cells. PMID- 29187528 TI - Regulation of lipid droplets by metabolically controlled Ldo isoforms. AB - Storage and consumption of neutral lipids in lipid droplets (LDs) are essential for energy homeostasis and tightly coupled to cellular metabolism. However, how metabolic cues are integrated in the life cycle of LDs is unclear. In this study, we characterize the function of Ldo16 and Ldo45, two splicing isoforms of the same protein in budding yeast. We show that Ldo proteins interact with the seipin complex, which regulates contacts between LDs and the endoplasmic reticulum (ER). Moreover, we show that the levels of Ldo16 and Ldo45 depend on the growth stage of cells and that deregulation of their relative abundance alters LD morphology, protein localization, and triglyceride content. Finally, we show that absence of Ldo proteins results in defects in LD morphology and consumption by lipophagy. Our findings support a model in which Ldo proteins modulate the activity of the seipin complex, thereby affecting LD properties. Moreover, we identify ER-LD contacts as regulatory targets coupling energy storage to cellular metabolism. PMID- 29187529 TI - SCWISh network is essential for survival under mechanical pressure. AB - Cells that proliferate within a confined environment build up mechanical compressive stress. For example, mechanical pressure emerges in the naturally space-limited tumor environment. However, little is known about how cells sense and respond to mechanical compression. We developed microfluidic bioreactors to enable the investigation of the effects of compressive stress on the growth of the genetically tractable model organism Saccharomyces cerevisiae We used this system to determine that compressive stress is partly sensed through a module consisting of the mucin Msb2 and the cell wall protein Sho1, which act together as a sensor module in one of the two major osmosensing pathways in budding yeast. This signal is transmitted via the MAPKKK kinase Ste11. Thus, we term this mechanosensitive pathway the "SMuSh" pathway, for Ste11 through Mucin/Sho1 pathway. The SMuSh pathway delays cells in the G1 phase of the cell cycle and improves cell survival in response to growth-induced pressure. We also found that the cell wall integrity (CWI) pathway contributes to the response to mechanical compressive stress. These latter results are confirmed in complimentary experiments in Mishra et al. [Mishra R, et al. (2017) Proc Natl Acad Sci USA, 10.1073/pnas.1709079114]. When both the SMuSh and the CWI pathways are deleted, cells fail to adapt to compressive stress, and all cells lyse at relatively low pressure when grown in confinement. Thus, we define a network that is essential for cell survival during growth under pressure. We term this mechanosensory system the SCWISh (survival through the CWI and SMuSh) network.

AB - Signal peptide peptidase (SPP) is an intramembrane aspartic protease involved in the maturation of the core protein of hepatitis C virus (HCV). The processing of HCV core protein by SPP has been reported to be critical for the propagation and pathogenesis of HCV. Here we examined the inhibitory activity of inhibitors for gamma-secretase, another intramembrane cleaving protease, against SPP, and our findings revealed that the dibenzoazepine-type structure in the gamma-secretase inhibitors is critical for the inhibition of SPP. The spatial distribution showed that the gamma-secretase inhibitor compound YO-01027 with the dibenzoazepine structure exhibits potent inhibiting activity against SPP in vitro and in vivo through the interaction of Val223 in SPP. Treatment with this SPP inhibitor suppressed the maturation of core proteins of all HCV genotypes without the emergence of drug-resistant viruses, in contrast to the treatment with direct acting antivirals. YO-01027 also efficiently inhibited the propagation of protozoa such as Plasmodium falciparum and Toxoplasma gondii These data suggest that SPP is an ideal target for the development of therapeutics not only against chronic hepatitis C but also against protozoiasis. PMID- 29187534 TI - Bulk magnetic domain stability controls paleointensity fidelity. AB - Nonideal, nonsingle-domain magnetic grains are ubiquitous in rocks; however, they can have a detrimental impact on the fidelity of paleomagnetic records-in particular the determination of ancient magnetic field strength (paleointensity), a key means of understanding the evolution of the earliest geodynamo and the formation of the solar system. As a consequence, great effort has been expended to link rock magnetic behavior to paleointensity results, but with little quantitative success. Using the most comprehensive rock magnetic and paleointensity data compilations, we quantify a stability trend in hysteresis data that characterizes the bulk domain stability (BDS) of the magnetic carriers in a paleomagnetic specimen. This trend is evident in both geological and archeological materials that are typically used to obtain paleointensity data and is therefore pervasive throughout most paleomagnetic studies. Comparing this trend to paleointensity data from both laboratory and historical experiments reveals a quantitative relationship between BDS and paleointensity behavior. Specimens that have lower BDS values display higher curvature on the paleointensity analysis plot, which leads to more inaccurate results. In-field quantification of BDS therefore reflects low-field bulk remanence stability. Rapid hysteresis measurements can be used to provide a powerful quantitative method for preselecting paleointensity specimens and postanalyzing previous studies, further improving our ability to select high-fidelity recordings of ancient magnetic fields. BDS analyses will enhance our ability to understand the evolution of the geodynamo and can help in understanding many fundamental Earth and planetary science questions that remain shrouded in controversy. PMID- 29187535 TI - Transient receptor potential channel 6 regulates abnormal cardiac S-nitrosylation in Duchenne muscular dystrophy. AB - Duchenne muscular dystrophy (DMD) is an X-linked disorder with dystrophin loss that results in skeletal and cardiac muscle weakening and early death. Loss of the dystrophin-sarcoglycan complex delocalizes nitric oxide synthase (NOS) to alter its signaling, and augments mechanosensitive intracellular Ca2+ influx. The latter has been coupled to hyperactivation of the nonselective cation channel, transient receptor potential canonical channel 6 (Trpc6), in isolated myocytes. As Ca2+ also activates NOS, we hypothesized that Trpc6 would help to mediate nitric oxide (NO) dysregulation and that this would be manifest in increased myocardial S-nitrosylation, a posttranslational modification increasingly implicated in neurodegenerative, inflammatory, and muscle disease. Using a recently developed dual-labeling proteomic strategy, we identified 1,276 S nitrosylated cysteine residues [S-nitrosothiol (SNO)] on 491 proteins in resting hearts from a mouse model of DMD (dmdmdx:utrn+/-). These largely consisted of mitochondrial proteins, metabolic regulators, and sarcomeric proteins, with 80% of them also modified in wild type (WT). S-nitrosylation levels, however, were increased in DMD. Genetic deletion of Trpc6 in this model (dmdmdx:utrn+/-:trpc6-/ ) reversed ~70% of these changes. Trpc6 deletion also ameliorated left ventricular dilation, improved cardiac function, and tended to reduce fibrosis. Furthermore, under catecholamine stimulation, which also increases NO synthesis and intracellular Ca2+ along with cardiac workload, the hypernitrosylated state remained as it did at baseline. However, the impact of Trpc6 deletion on the SNO proteome became less marked. These findings reveal a role for Trpc6-mediated hypernitrosylation in dmdmdx:utrn+/- mice and support accumulating evidence that implicates nitrosative stress in cardiac and muscle disease. PMID- 29187536 TI - Inflammasome Antagonism by Human Parainfluenza Virus Type 3 C Protein. AB - Human parainfluenza virus type 3 (HPIV3) is a negative-sense single-stranded RNA virus belonging to the Paramyxoviridae family. HPIV3 is a lung-tropic virus causing airway diseases, including pneumonia, croup, and bronchiolitis, during infancy and childhood. The activation of the inflammasome by pathogens results in the production of proinflammatory cytokines such as interleukin-1beta (IL-1beta) during infection. Thus, the inflammasome-mediated proinflammatory response plays a critical role in regulating the immune response and virus clearance. The inflammasome is a multimeric protein complex triggering caspase-1 activation. Activated caspase-1 cleaves pro-IL-1beta into its mature (and active) secretory form. Our study revealed inflammasome activation in macrophages following HPIV3 infection. Specifically, the activation of the NLRP3/ASC inflammasome resulted in the production of mature IL-1beta from HPIV3-infected cells. Furthermore, Toll like receptor 2 (TLR2) activation (first signal) and potassium efflux (second signal) constituted two cellular events mediating inflammasome activation following HPIV3 infection. During our studies, we surprisingly identified the HPIV3 C protein as an antagonist of inflammasome activation. The HPIV3 C protein is an accessory protein encoded by the open reading frame of the viral phosphoprotein (P) gene. The HPIV3 C protein interacted with the NLRP3 protein and blocked inflammasome activation by promoting the proteasomal degradation of the NLRP3 protein. Thus, our studies report NLRP3/ASC inflammasome activation by HPIV3 via TLR2 signaling and potassium efflux. Furthermore, we have identified HPIV3 C as a viral component involved in antagonizing inflammasome activation.IMPORTANCE Human parainfluenza virus type 3 (HPIV3) is a paramyxovirus that causes respiratory tract diseases during infancy and childhood. Currently, there is no effective vaccine or antiviral therapy for HPIV3. Therefore, in order to develop anti-HPIV3 agents (therapeutics and vaccines), it is important to study the HPIV3-host interaction during the immune response. Inflammasomes play an important role in the immune response. Inflammasome activation by HPIV3 has not been previously reported. Our studies demonstrated inflammasome activation by HPIV3 in macrophages. Specifically, HPIV3 activated the NLRP3/ASC inflammasome by TLR2 activation and potassium efflux. C proteins of paramyxoviruses are accessory proteins encoded by the viral phosphoprotein gene. The role of the C protein in inflammasome regulation was unknown. Surprisingly, our studies revealed that the HPIV3 C protein antagonizes inflammasome activation. In addition, we highlighted for the first time a mechanism utilized by paramyxovirus accessory proteins to block inflammasome activation. The HPIV3 C protein interacted with the NLRP3 protein to trigger the proteasomal degradation of the NLRP3 protein. PMID- 29187537 TI - Host specific glycans are correlated with susceptibility to infection by lagoviruses, but not with their virulence. AB - The rabbit hemorrhagic disease virus (RHDV) and the European brown hare syndrome virus (EBHSV) are two lagoviruses from the family Caliciviridae that cause fatal diseases in two leporid genera, Oryctolagus and Lepus, respectively. In the last few years, several examples of host jumps of lagoviruses among leporids were recorded. In addition, a new pathogenic genotype of RHDV emerged and many non pathogenic strains of lagoviruses have been described. The molecular mechanisms behind host shifts and the emergence of virulence are unknown. Since RHDV uses glycans of the histo-blood group antigen type as attachment factors to initiate infection, we studied if glycan specificities of the new pathogenic RHDV genotype, non-pathogenic lagoviruses and EBHSV potentially play a role in determining host range and virulence of lagoviruses. We observed binding to A, B or H antigens of the histo-blood group family for all strains known to primarily infect European rabbits (Oryctolagus cuniculus), that have recently been classified as GI strains. Yet, we could not explain the emergence of virulence since similar glycan specificities were found between several pathogenic and non pathogenic strains. By contrast, EBHSV, recently classified as GII.1, bound to terminal beta-linked N-acetylglucosamine residues of O-glycans. Expression of these attachment factors in the upper respiratory and digestive tracts in three lagomorph species (Oryctolagus cuniculus, Lepus europaeus and Sylvilagus floridanus) showed species-specific patterns regarding the susceptibility to infection by these viruses, indicating that species-specific glycan expression is likely a major contributor to lagoviruses host specificity and range.IMPORTANCE Lagoviruses constitute a genus of the Caliciviridae family, comprising highly pathogenic viruses, RHDV and EBHSV, which infect rabbits and hares, respectively. Recently, non-pathogenic strains were discovered and new pathogenic strains have emerged. In addition, host jumps between lagomorphs are observed. The mechanisms responsible for the emergence of pathogenicity and host-species range are unknown. Previous studies showed that RHDV strains attach to glycans expressed in the upper respiratory and digestive tracts of rabbits, the likely doors of virus entry. Here we studied the glycan-binding properties of novel pathogenic and non pathogenic strains looking for a link between glycan-binding and virulence or between glycan specificity and host range. We found that glycan binding did not correlate with virulence. However, expression of glycan motifs in the upper respiratory and digestive tracts of lagomorphs revealed species-specific patterns associated with the host range of the virus strains, suggesting that glycan diversity contributes to lagoviruses' host range. PMID- 29187538 TI - The Absence of DHHC3 Affects Primary and Latent Herpes Simplex Virus 1 Infection. AB - UL20, an essential herpes simplex virus 1 (HSV-1) protein, is involved in cytoplasmic envelopment of virions and virus egress. We reported recently that UL20 can bind to a host protein encoded by the zinc finger DHHC-type containing 3 (ZDHHC3) gene (also known as Golgi-specific DHHC zinc finger protein [GODZ]). Here, we show for the first time that HSV-1 replication is compromised in murine embryonic fibroblasts (MEFs) isolated from GODZ-/- mice. The absence of GODZ resulted in blocking palmitoylation of UL20 and altered localization and expression of UL20 and glycoprotein K (gK); the expression of gB and gC; and the localization and expression of tegument and capsid proteins within HSV-1-infected MEFs. Electron microscopy revealed that the absence of GODZ limited the maturation of virions at multiple steps and affected the localization of virus and endoplasmic reticulum morphology. Virus replication in the eyes of ocularly HSV-1-infected GODZ-/- mice was significantly lower than in HSV-1-infected wild type (WT) mice. The levels of UL20, gK, and gB transcripts in the corneas of HSV 1-infected GODZ-/- mice on day 5 postinfection were markedly lower than in WT mice, whereas only UL20 transcripts were reduced in trigeminal ganglia (TG). In addition, HSV-1-infected GODZ-/- mice showed notably lower levels of corneal scarring, and HSV-1 latency reactivation was also reduced. Thus, normal HSV-1 infectivity and viral pathogenesis are critically dependent on GODZ-mediated palmitoylation of viral UL20.IMPORTANCE HSV-1 infection is widespread. Ocular infection can cause corneal blindness; however, approximately 70 to 90% of American adults exposed to the virus show no clinical symptoms. In this study, we show for the first time that the absence of a zinc finger protein called GODZ affects primary and latent infection, as well as reactivation, in ocularly infected mice. The reduced virus infectivity is due to the absence of the GODZ interaction with HSV-1 UL20. These results strongly suggest that binding of UL20 to GODZ promotes virus infectivity in vitro and viral pathogenesis in vivo. PMID- 29187539 TI - Prasinovirus Attack of Ostreococcus Is Furtive by Day but Savage by Night. AB - Prasinoviruses are large DNA viruses that infect diverse genera of green microalgae worldwide in aquatic ecosystems, but molecular knowledge of their life cycles is lacking. Several complete genomes of both these viruses and their marine algal hosts are now available and have been used to show the pervasive presence of these species in microbial metagenomes. We have analyzed the life cycle of Ostreococcus tauri virus 5 (OtV5), a lytic virus, using transcriptome sequencing (RNA-Seq) from 12 time points of healthy or infected Ostreococcus tauri cells over a day/night cycle in culture. In the day, viral gene transcription remained low while host nitrogen metabolism gene transcription was initially strongly repressed for two successive time points before being induced for 8 h, but during the night, viral transcription increased steeply while host nitrogen metabolism genes were repressed and many host functions that are normally reduced in the dark appeared to be compensated either by genes expressed from the virus or by increased expression of a subset of 4.4% of the host's genes. Some host cells underwent lysis progressively during the night, but a larger proportion were lysed the following morning. Our data suggest that the life cycles of algal viruses mirror the diurnal rhythms of their hosts.IMPORTANCE Prasinoviruses are common in marine environments, and although several complete genomes of these viruses and their hosts have been characterized, little is known about their life cycles. Here we analyze in detail the transcriptional changes occurring over a 27-h-long experiment in a natural diurnal rhythm, in which the growth of host cells is to some extent synchronized, so that host DNA replication occurs late in the day or early in the night and cell division occurs during the night. Surprisingly, viral transcription remains quiescent over the daytime, when the most energy (from light) is available, but during the night viral transcription activates, accompanied by expression of a few host genes that are probably required by the virus. Although our experiment was accomplished in the lab, cyclical changes have been documented in host transcription in the ocean. Our observations may thus be relevant for eukaryotic phytoplankton in natural environments. PMID- 29187540 TI - General Model for Retroviral Capsid Pattern Recognition by TRIM5 Proteins. AB - Restriction factors are intrinsic cellular defense proteins that have evolved to block microbial infections. Retroviruses such as HIV-1 are restricted by TRIM5 proteins, which recognize the viral capsid shell that surrounds, organizes, and protects the viral genome. TRIM5alpha uses a SPRY domain to bind capsids with low intrinsic affinity (KD of >1 mM) and therefore requires higher-order assembly into a hexagonal lattice to generate sufficient avidity for productive capsid recognition. TRIMCyp, on the other hand, binds HIV-1 capsids through a cyclophilin A domain, which has a well-defined binding site and higher affinity (KD of ~10 MUM) for isolated capsid subunits. Therefore, it has been argued that TRIMCyp proteins have dispensed with the need for higher-order assembly to function as antiviral factors. Here, we show that, consistent with its high degree of sequence similarity with TRIM5alpha, the TRIMCyp B-box 2 domain shares the same ability to self-associate and facilitate assembly of a TRIMCyp hexagonal lattice that can wrap about the HIV-1 capsid. We also show that under stringent experimental conditions, TRIMCyp-mediated restriction of HIV-1 is indeed dependent on higher-order assembly. Both forms of TRIM5 therefore use the same mechanism of avidity-driven capsid pattern recognition.IMPORTANCE Rhesus macaques and owl monkeys are highly resistant to HIV-1 infection due to the activity of TRIM5 restriction factors. The rhesus macaque TRIM5alpha protein blocks HIV-1 through a mechanism that requires self-assembly of a hexagonal TRIM5alpha lattice around the invading viral core. Lattice assembly amplifies very weak interactions between the TRIM5alpha SPRY domain and the HIV-1 capsid. Assembly also promotes dimerization of the TRIM5alpha RING E3 ligase domain, resulting in synthesis of polyubiquitin chains that mediate downstream steps of restriction. In contrast to rhesus TRIM5alpha, the owl monkey TRIM5 homolog, TRIMCyp, binds isolated HIV-1 CA subunits much more tightly through its cyclophilin A domain and therefore was thought to act independently of higher-order assembly. Here, we show that TRIMCyp shares the assembly properties of TRIM5alpha and that both forms of TRIM5 use the same mechanism of hexagonal lattice formation to promote viral recognition and restriction. PMID- 29187542 TI - Type III Interferon Restriction by Porcine Epidemic Diarrhea Virus and the Role of Viral Protein nsp1 in IRF1 Signaling. AB - Type III interferons (IFNs) play a vital role in maintaining the antiviral state of the mucosal epithelial surface in the gut, and in turn, enteric viruses may have evolved to evade the type III IFN responses during infection. To study the possible immune evasion of the type III IFN response by porcine epidemic diarrhea virus (PEDV), a line of porcine intestinal epithelial cells was developed as a cell model for PEDV replication. IFN-lambda1 and IFN-lambda3 inhibited PEDV replication, indicating the anti-PEDV activity of type III IFNs. Of the 21 PEDV proteins, nsp1, nsp3, nsp5, nsp8, nsp14, nsp15, nsp16, open reading frame 3 (ORF3), E, M, and N were found to suppress type III IFN activities, and IRF1 (interferon regulatory factor 1) signaling mediated the suppression. PEDV specifically inhibited IRF1 nuclear translocation. The peroxisome is the innate antiviral signaling platform for the activation of IRF1-mediated IFN-lambda production, and the numbers of peroxisomes were found to be decreased in PEDV infected cells. PEDV nsp1 blocked the nuclear translocation of IRF1 and reduced the number of peroxisomes to suppress IRF1-mediated type III IFNs. Mutational studies showed that the conserved residues of nsp1 were crucial for IRF1-mediated IFN-lambda suppression. Our study for the first time provides evidence that the porcine enteric virus PEDV downregulates and evades IRF1-mediated type III IFN responses by reducing the number of peroxisomes.IMPORTANCE Porcine epidemic diarrhea virus (PEDV) is a highly contagious enteric coronavirus that emerged in swine in the United States and has caused severe economic losses. PEDV targets intestinal epithelial cells in the gut, and intestinal epithelial cells selectively induce and respond to the production of type III interferons (IFNs). However, little is known about the modulation of the type III IFN response by PEDV in intestinal epithelial cells. In this study, we established a porcine intestinal epithelial cell model for PEDV replication. We found that PEDV inhibited IRF1-mediated type III IFN production by decreasing the number of peroxisomes in porcine intestinal epithelial cells. We also demonstrated that the conserved residues in the PEDV nsp1 protein were crucial for IFN suppression. This study for the first time shows PEDV evasion of the type III IFN response in intestinal epithelial cells, and it provides valuable information on host cell virus interactions not only for PEDV but also for other enteric viral infections in swine. PMID- 29187541 TI - Exosomes Mediate Intercellular Transmission of Porcine Reproductive and Respiratory Syndrome Virus. AB - Exosomes are small membrane-enclosed vesicles produced by various cells and actively released into the extracellular space. They participate in intercellular communication and transfer of biologically active proteins, lipids, and nucleic acids. Accumulating evidence suggests that exosomes derived from cells infected by some viruses selectively encapsulate viral proteins, genetic materials, or even virions to mediate cell-to-cell communication and/or virus transmission. Porcine reproductive and respiratory syndrome virus (PRRSV) is an Arterivirus that has been devastating the global swine industry since the late 1980s. Recent studies have shown that major proteins secreted from PRRSV-infected cells are exosomal proteins and that the serum-derived exosomes from PRRSV-infected pigs contain viral proteins. However, the role of exosomes in PRRSV infection remains unclear. In this study, purified exosomes isolated from PRRSV-infected cells were shown with reverse transcription-PCR and mass spectrometry to contain viral genomic RNA and partial viral proteins. Furthermore, exosomes from PRRSV-infected cells established productive infection in both PRRSV-susceptible and nonsusceptible cells. More importantly, exosome-mediated infection was not completely blocked by PRRSV-specific neutralizing antibodies. In summary, this study demonstrated that exosomes can mediate PRRSV transmission and are even resistant to antibody neutralization, identifying a potential immune evasion mechanism utilized by PRRSV.IMPORTANCE Exosomes have recently been characterized as bioactive vesicles that function to promote intercellular communication. The exosomes from virally infected cells containing altered compositions confer numerous novel functionalities. A study of the secretome of cells infected with PRRSV indicated that the exosomal pathway is strongly activated by PRRSV infection. Here, we demonstrate that PRRSV can utilize host exosomes to infect naive healthy cells. Furthermore, exosome-mediated viral transmission is largely resistant to PRRSV-specific neutralizing antibodies. Our study provides novel insights into an alternative mechanism of PRRSV transmission that can compromise the host's anti-PRRSV immune response. PMID- 29187543 TI - A proteomic survey of Junin virus interactions with human proteins reveals host factors required for arenavirus replication. AB - Arenaviruses are negative-strand, enveloped RNA viruses that cause significant human disease. In particular, Junin mammarenvirus (JUNV) is the etiologic agent of Argentine hemorrhagic fever. At present, little is known about the cellular proteins that the arenavirus matrix protein (Z) hijacks to accomplish its various functions, including driving the process of virus release. Further, there is a little knowledge regarding host proteins incorporated into arenavirus particles and their importance for virion function. To address these deficiencies, we used mass spectrometry to identify human proteins that (i) interact with the JUNV matrix protein inside of cells or within virus-like particles (VLPs) and/or (ii) are incorporated into bona fide JUNV strain Candid #1 particles. Bioinformatic analyses revealed that multiple classes of human proteins were overrepresented in the datasets, including ribosomal proteins, Ras superfamily proteins, and endosomal sorting complex required for transport (ESCRT) proteins. Several of these proteins were required for the propagation of JUNV (ARF1, ATP6V0D1 and PRDX3), lymphocytic choriomeningitis mammarenavirus (LCMV) (Rab5c), or both viruses (ATP5B, IMPDH2). Further, we show that release of infectious JUNV particles, but not LCMV particles, requires a functional ESCRT pathway and that ATP5B and IMPDH2 are required for JUNV budding. In summary, we have provided a large-scale map of host machinery that associates with JUNV and identified key human proteins required for its propagation. This dataset provides a resource for the field to guide antiviral target discovery and to better understand the biology of the arenavirus matrix protein and the importance of host proteins for virion function.IMPORTANCE Arenaviruses are deadly human pathogens for which there are no United States Food and Drug Administration-approved vaccines and only limited treatment options. Little is known about the host proteins that are incorporated into arenavirus particles or that associate with its multifunctional matrix protein. Using Junin mammarenavirus (JUNV), the causative agent of Argentine hemorrhagic fever, as a model organism, we mapped the human proteins that are incorporated into JUNV particles or that associate with the JUNV matrix protein. Functional analysis revealed host machinery that is required for JUNV propagation, including the cellular ESCRT pathway. This study improves our understanding of critical arenavirus-host interactions and provides a dataset that will guide future studies to better understand arenavirus pathogenesis and identify novel host proteins that can be therapeutically targeted. PMID- 29187544 TI - Genetically Intact but Functionally Impaired HIV-1 Env Glycoproteins in the T Cell Reservoir. AB - HIV-infected subjects under antiretroviral treatment (ART) harbor a persistent viral reservoir in resting CD4+ T cells, which accounts for the resurgence of HIV replication after ART interruption. A large majority of HIV reservoir genomes are genetically defective, but even among intact proviruses few seem able to generate infectious virus. To understand this phenomenon, we examined the function and expression of HIV envelope glycoproteins reactivated from the reservoir of four HIV-infected subjects under suppressive ART. We studied full-length genetically intact env sequences from both replicative viruses and cell-associated mRNAs. We found that these Env proteins varied extensively in fusogenicity and infectivity, with strongest functional defects found in Envs from cell-associated mRNAs. Env functional impairments were essentially explained by defects in Env protein expression. Our results support the idea that defects in HIV Env expression, preventing cytopathic or immune HIV clearance, contribute to the persistence of the HIV T-cell reservoir in vivoIMPORTANCE In most individuals, evolution of HIV infection is efficiently controlled on the long-term by combination antiviral therapies. These treatments, however, fail to eradicate HIV from the infected subjects, a failure that results both in resurgence of virus replication and in resumption of HIV pathogenicity when the treatment is stopped. HIV resurgence, in these instances, is widely assumed to emerge from a reservoir of silent virus integrated in the genomes of a small number of T lymphocytes. The silent HIV reservoir is mostly composed of heavily deleted or mutated HIV DNA. Moreover, among the seemingly intact remaining HIV, only very few are actually able to efficiently propagate in tissue culture. In this study, we find that intact HIV in the reservoir often carry strong defects in their capacity to promote fusion to neighboring cells and infection of target cells, a defect related to the function and expression of the HIV envelope glycoprotein. Impaired envelope glycoprotein expression and function could explain why cells harboring these viruses tend to remain undetected and unharmed in the reservoir. PMID- 29187547 TI - Effect of sensory attenuation on cortical movement-related oscillations. AB - This study examined the impact of induced sensory deficits on cortical, movement related oscillations measured using electroencephalography (EEG). We hypothesized that EEG patterns in healthy subjects with induced sensory reduction would be comparable to EEG found after chronic loss of sensory feedback. EEG signals from 64 scalp locations were measured from 10 healthy subjects. Participants dorsiflexed their ankle after prolonged vibration of the tibialis anterior (TA). Beta band time frequency decompositions were calculated using wavelets and compared across conditions. Changes in patterns of movement-related brain activity were observed following attenuation of sensory feedback. A significant decrease in beta power of event-related synchronization was associated with simple ankle dorsiflexion after prolonged vibration of the TA. Attenuation of sensory feedback in young, healthy subjects led to a corresponding decrease in beta band synchronization. This temporary change in beta oscillations suggests that these modulations are a mechanism for sensorimotor integration. The loss of sensory feedback found in spinal cord injury patients contributes to changes in EEG signals underlying motor commands. Similar alterations in cortical signals in healthy subjects with reduced sensory feedback implies these changes reflect normal sensorimotor integration after reduced sensory input rather than brain plasticity. NEW & NOTEWORTHY Transient attenuation of sensory afferents in young, healthy adults led to similar changes in brain activity found previously in volunteers with incomplete spinal cord injury. Beta band power associated with ankle movement in these controls was attenuated after prolonged vibration of the tibialis anterior. Evoked potential measurements suggest that prolonged vibration reduces phasing across trials as the mechanism behind this attenuation of cortical activity. PMID- 29187546 TI - Pathogenesis, humoral immune responses and transmission between co-housed animals in a ferret model of human RSV infection. AB - Small animal models have been used to obtain many insights regarding the pathogenesis and immune responses induced following infection with human respiratory syncytial virus (hRSV). Amongst those described to date, infections in cotton rats, mice, guinea pigs, chinchillas and Syrian hamsters with hRSV strains Long and/or A2 have been well characterised, although clinical isolates have also been examined. Ferrets are also susceptible to hRSV infection but the pathogenesis and immune responses elicited following infection have not been well characterised. Herein, we describe the infection of adult ferrets with hRSV Long or A2 via the intranasal route and characterised virus replication, as well as cytokine induction, in the upper and lower airways. Virus replication and cytokine induction during the acute phase of infection (days 0-15 post-infection) were similar between the two strains and both elicited high levels of F glycoprotein-specific binding and neutralising antibodies following virus clearance (days 16-22 post-infection). Importantly, we demonstrate transmission from experimentally infected donor ferrets to co-housed naive recipients and have characterised virus replication and cytokine induction in the upper airways of infected contact animals. Together, these studies provide a direct comparison of the pathogenesis of hRSV Long and A2 in ferrets and highlight the potential of this animal model to study serological responses and examine interventions that limit transmission of hRSV.IMPORTANCE Ferrets have been widely used to study pathogenesis, immunity and transmission following human influenza virus infections, however far less is known regarding the utility of the ferret model to study hRSV infections. Following intranasal (IN) infection of adult ferrets with the well characterised Long or A2 strains of hRSV, we report virus replication and cytokine induction in the upper and lower airways, as well as the development of virus-specific humoral responses. Importantly, we demonstrate transmission of hRSV from experimentally infected donor ferrets to co-housed naive recipients. Together, these findings significantly enhance our understanding of the utility of the ferret as a small animal model to investigate aspects of hRSV pathogenesis and immunity. PMID- 29187545 TI - Novel Insect-Specific Eilat Virus-Based Chimeric Vaccine Candidates Provide Durable, Mono- and Multivalent, Single-Dose Protection against Lethal Alphavirus Challenge. AB - Most alphaviruses are mosquito borne and exhibit a broad host range, infecting many different vertebrates, including birds, rodents, equids, humans, and nonhuman primates. Recently, a host-restricted, mosquito-borne alphavirus, Eilat virus (EILV), was described with an inability to infect vertebrate cells based on defective attachment and/or entry, as well as a lack of genomic RNA replication. We investigated the utilization of EILV recombinant technology as a vaccine platform against eastern (EEEV) and Venezuelan equine encephalitis viruses (VEEV), two important pathogens of humans and domesticated animals. EILV chimeras containing structural proteins of EEEV or VEEV were engineered and successfully rescued in Aedes albopictus cells. Cryo-electron microscopy reconstructions at 8 and 11 A of EILV/VEEV and EILV/EEEV, respectively, showed virion and glycoprotein spike structures similar to those of VEEV-TC83 and other alphaviruses. The chimeras were unable to replicate in vertebrate cell lines or in brains of newborn mice when injected intracranially. Histopathologic examinations of the brain tissues showed no evidence of pathological lesions and were indistinguishable from those of mock-infected animals. A single-dose immunization of either monovalent or multivalent EILV chimera(s) generated neutralizing antibody responses and protected animals against lethal challenge 70 days later. Lastly, a single dose of monovalent EILV chimeras generated protective responses as early as day 1 postvaccination and partial or complete protection by day 6. These data demonstrate the safety, immunogenicity, and efficacy of novel insect specific EILV-based chimeras as potential EEEV and VEEV vaccines.IMPORTANCE Mostly in the last decade, insect-specific viruses have been discovered in several arbovirus families. However, most of these viruses are not well studied and largely have been ignored. We explored the use of the mosquito-specific alphavirus EILV as an alphavirus vaccine platform in well-established disease models for eastern (EEE) and Venezuelan equine encephalitis (VEE). EILV-based chimeras replicated to high titers in a mosquito cell line yet retained their host range restriction in vertebrates both in vitro and in vivo In addition, the chimeras generated immune responses that were higher than those of other human and/or equine vaccines. These findings indicate the feasibility of producing a safe, efficacious, mono- or multivalent vaccine against the encephalitic alphaviruses VEEV and EEEV. Lastly, these data demonstrate how host-restricted, insect-specific viruses can be engineered to develop vaccines against related pathogenic arboviruses that cause severe disease in humans and domesticated animals. PMID- 29187548 TI - Estimating properties of the fast and slow adaptive processes during sensorimotor adaptation. AB - Experience of a prediction error recruits multiple motor learning processes, some that learn strongly from error but have weak retention and some that learn weakly from error but exhibit strong retention. These processes are not generally observable but are inferred from their collective influence on behavior. Is there a robust way to uncover the hidden processes? A standard approach is to consider a state space model where the hidden states change following experience of error and then fit the model to the measured data by minimizing the squared error between measurement and model prediction. We found that this least-squares algorithm (LMSE) often yielded unrealistic predictions about the hidden states, possibly because of its neglect of the stochastic nature of error-based learning. We found that behavioral data during adaptation was better explained by a system in which both error-based learning and movement production were stochastic processes. To uncover the hidden states of learning, we developed a generalized expectation maximization (EM) algorithm. In simulation, we found that although LMSE tracked the measured data marginally better than EM, EM was far more accurate in unmasking the time courses and properties of the hidden states of learning. In a power analysis designed to measure the effect of an intervention on sensorimotor learning, EM significantly reduced the number of subjects that were required for effective hypothesis testing. In summary, we developed a new approach for analysis of data in sensorimotor experiments. The new algorithm improved the ability to uncover the multiple processes that contribute to learning from error. NEW & NOTEWORTHY Motor learning is supported by multiple adaptive processes, each with distinct error sensitivity and forgetting rates. We developed a generalized expectation maximization algorithm that uncovers these hidden processes in the context of modern sensorimotor learning experiments that include error-clamp trials and set breaks. The resulting toolbox may improve the ability to identify the properties of these hidden processes and reduce the number of subjects needed to test the effectiveness of interventions on sensorimotor learning. PMID- 29187549 TI - Quantitative input-output relationships between human soleus muscle spindle afferents and motoneurons. AB - A method is described that, for the first time, allows instantaneous estimation of the Ia fiber input to human soleus motoneurons following electrical stimulation of the tibial nerve. The basis of the method is to determine the thresholds of the most and least excitable 1a fibers to electrical stimulation, and to treat the intervening thresholds as having a normal distribution about the mean; the validity of this approach is discussed. It was found that, for the same Ia fiber input, the percentage of soleus motoneurons contributing to the H (Hoffmann)-reflex differed considerably among subjects; when the results were pooled, however, there was an approximately linear relationship between Ia input and motoneuron output. Weak extension of the great toe diminished the soleus motoneuron reflex discharge in all but 2 of 16 subjects; the results for weak ankle plantarflexion were less consistent, but overall, there was a reduction in soleus motoneuron output also. The methodology should provide new insights into disorders of movement and tone, especially as it permits estimates of motoneuron depolarization to be made. NEW & NOTEWORTHY Assuming a normal distribution of Ia fiber thresholds to electrical stimulation and using the H-reflex, we determined for the first time an Ia input-alpha-motoneuron output relationship for the human soleus muscle. The relationship varies greatly among subjects but, overall, is approximately linear. Minimal contraction of a toe muscle alters the relationship dramatically, probably due to presynaptic inhibition of Ia fibers. Drawing on the literature, we can calculate changes in alpha-motoneuron membrane potential. PMID- 29187550 TI - Quantitative relations between BOLD responses, cortical energetics, and impulse firing. AB - The blood oxygen level-dependent (BOLD) functional magnetic resonance imaging signal arises as a consequence of changes in blood flow and oxygen usage that in turn are modulated by changes in neural activity. Much attention has been given to both theoretical and experimental aspects of the energetics but not to the neural activity. Here we identify the best energetic theory for the steady-state BOLD signal on the basis of correct predictions of experimental observations. This theory is then used, together with the recently determined relationship between energetics and neural activity, to predict how the BOLD signal changes with activity. Unlike existing treatments, this new theory incorporates a nonzero baseline activity in a completely consistent way and is thus able to account for both sustained positive and negative BOLD signals. We also show that the increase in BOLD signal for a given increase in activity is significantly smaller the larger the baseline activity, as is experimentally observed. Furthermore, the decline of the positive BOLD signal arising from deeper cortical laminae in response to an increase in neural firing is shown to arise as a consequence of the larger baseline activity in deeper laminae. Finally, we provide quantitative relations integrating BOLD responses, energetics, and impulse firing, which among other predictions give the same results as existing theories when the baseline activity is zero. NEW & NOTEWORTHY We use a recently established relation between energetics and neural activity to give a quantitative account of BOLD dependence on neural activity. The incorporation of a nonzero baseline neural activity accounts for positive and negative BOLD signals, shows that changes in neural activity give BOLD changes that are smaller the larger the baseline, and provides a basis for the observed inverse relation between BOLD responses and the depth of cortical laminae giving rise to them. PMID- 29187552 TI - Implantable computer-controlled adaptive multielectrode positioning system. AB - Acute neuronal recordings performed with metal microelectrodes in nonhuman primates allow investigating the neural substrate of complex cognitive behaviors. Yet the daily reinsertion and positioning of the electrodes prevents recording from many neurons simultaneously, limiting the suitability of these types of recordings for brain-computer interface applications or for large-scale population statistical methods on a trial-by-trial basis. In contrast, chronically implanted multielectrode arrays offer the opportunity to record from many neurons simultaneously, but immovable electrodes prevent optimization of the signal during and after implantation and cause the tissue response to progressively impair the transduced signal quality, thereby limiting the number of different neurons that can be recorded over the lifetime of the implant. Semichronically implanted matrices of electrodes, instead, allow individually movable electrodes in depth and achieve higher channel count compared with acute methods, hence partially overcoming these limitations. Existing semichronic systems with higher channel count lack computerized control of electrode movements, leading to limited user-friendliness and uncertainty in depth positioning. Here we demonstrate a chronically implantable adaptive multielectrode positioning system with detachable drive for computerized depth adjustment of individual electrodes over several millimeters. This semichronic 16 channel system is designed to optimize the simultaneous yield of units in an extended period following implantation since the electrodes can be independently depth adjusted with minimal effort and their signal quality continuously assessed. Importantly, the electrode array is designed to remain within a chronic recording chamber for a prolonged time or can be used for acute recordings with high signal-to-noise ratio in the cerebral cortex of nonhuman primates. NEW & NOTEWORTHY We present a 16-channel motorized, semichronic multielectrode array with individually depth-adjustable electrodes to record in the cerebral cortex of nonhuman primates. Compared with fixed-geometry arrays, this system allows repeated reestablishing of single neuron isolation. Compared with manually adjustable arrays it benefits from computer-controlled positioning. Compared with motorized semichronic systems it allows higher channel counts due to a robotic single actuator approach. Overall the system is designed to optimize the simultaneous yield of units over the course of implantation. PMID- 29187551 TI - Model of a bilateral Brown-type central pattern generator for symmetric and asymmetric locomotion. AB - The coordinated activity of muscles is produced in part by spinal rhythmogenic neural circuits, termed central pattern generators (CPGs). A classical CPG model is a system of coupled oscillators that transform locomotor drive into coordinated and gait-specific patterns of muscle recruitment. The network properties of this conceptual model can be simulated by a system of ordinary differential equations with a physiologically inspired coupling locus of interactions capturing the timing relationship for bilateral coordination of limbs in locomotion. Whereas most similar models are solved numerically, it is intriguing to have a full analytical description of this plausible CPG architecture to illuminate the functionality within this structure and to expand it to include steering control. Here, we provided a closed-form analytical solution contrasted against the previous numerical method. The evaluation time of the analytical solution was decreased by an order of magnitude when compared with the numerical approach (relative errors, <0.01%). The analytical solution tested and supported the previous finding that the input to the model can be expressed in units of the desired limb locomotor speed. Furthermore, we performed parametric sensitivity analysis in the context of controlling steering and documented two possible mechanisms associated with either an external drive or intrinsic CPG parameters. The results identify specific propriospinal pathways that may be associated with adaptations within the CPG structure. The model offered several network configurations that may generate the same behavioral outcomes. NEW & NOTEWORTHY Using a simple process of leaky integration, we developed an analytical solution to a robust model of spinal pattern generation. We analyzed the ability of this neural element to exert locomotor control of the signal associated with limb speeds and tested the ability of this simple structure to embed steering control using the velocity signal in the model's inputs or within the internal connectivity of its elements.

AB - Transcranial current stimulation (tCS) modulates brain dynamics using weak electric fields. Given the pathological changes in brain network oscillations in neurological and psychiatric illnesses, using alternating electric field waveforms that engage rhythmic activity has been proposed as a targeted, network level treatment approach. Previous studies have investigated the effects of electric fields at the neuronal level. However, the biophysical basis of the cellular response to electric fields has remained limited. Here, we characterized the frequency-dependent response of different compartments in a layer V pyramidal neuron to exogenous electric fields to dissect the relative contributions of voltage-gated ion channels and neuronal morphology. Hyperpolarization-activated cation current (Ih) in the distal dendrites was the primary ionic mechanism shaping the model's response to electric field stimulation and caused subthreshold resonance in the tuft at 20 +/- 4 Hz. In contrast, subthreshold Ih mediated resonance in response to local sinusoidal current injection was present in all model compartments at 11 +/- 2 Hz. The frequencies of both resonance responses were modulated by Ih conductance density. We found that the difference in resonance frequency between the two stimulation types can be explained by the fact that exogenous electric fields simultaneously polarize the membrane potentials at the distal ends of the neuron (relative to field direction) in opposite directions. Our results highlight the role of Ih in shaping the cellular response to electric field stimulation and suggest that the common model of tCS as a weak somatic current injection fails to capture the cellular effects of electric field stimulation. NEW & NOTEWORTHY Modulation of cortical oscillation by brain stimulation serves as a tool to understand the causal role of network oscillations in behavior and is a potential treatment modality that engages impaired network oscillations in disorders of the central nervous system. To develop targeted stimulation paradigms, cellular-level effects must be understood. We demonstrate that hyperpolarization-activated cation current (Ih) and cell morphology cooperatively shape the response to applied alternating electric fields. PMID- 29187554 TI - Clustering of heading selectivity and perception-related activity in the ventral intraparietal area. AB - The ventral intraparietal area (VIP) of the macaque brain is a multimodal cortical region, with many cells tuned to both optic flow and vestibular stimuli. Responses of many VIP neurons also show robust correlations with perceptual judgments during a fine heading discrimination task. Previous studies have shown that heading tuning based on optic flow is represented in a clustered fashion in VIP. However, it is unknown whether vestibular self-motion selectivity is clustered in VIP. Moreover, it is not known whether stimulus- and choice-related signals in VIP show clustering in the context of a heading discrimination task. To address these issues, we compared the response characteristics of isolated single units (SUs) with those of the undifferentiated multiunit (MU) activity corresponding to several neighboring neurons recorded from the same microelectrode. We find that MU activity typically shows selectivity similar to that of simultaneously recorded SUs, for both the vestibular and visual stimulus conditions. In addition, the choice-related activity of MU signals, as quantified using choice probabilities, is correlated with the choice-related activity of SUs. Overall, these findings suggest that both sensory and choice-related signals regarding self-motion are clustered in VIP. NEW & NOTEWORTHY We demonstrate, for the first time, that the vestibular tuning of ventral intraparietal area (VIP) neurons in response to both translational and rotational motion is clustered. In addition, heading discriminability and choice-related activity are also weakly clustered in VIP. PMID- 29187555 TI - Complementary metrics of human auditory nerve function derived from compound action potentials. AB - Declines in auditory nerve (AN) function contribute to suprathreshold auditory processing and communication deficits in individuals with normal hearing, hearing loss, hyperacusis, and tinnitus. Procedures to characterize AN loss or dysfunction in humans are limited. We report several novel complementary metrics using the compound action potential (CAP), a direct measure of summated AN activity. Together, these metrics may be used to characterize AN function noninvasively in humans. We examined how these metrics change with stimulus intensity and interpreted these changes within a framework of known physiological properties of the basilar membrane and AN. Our results reveal how neural synchrony and the recruitment of AN fibers with longer first-spike latencies likely contribute to the CAP, affect auditory processing, and differ with noise exposure history in younger adults with normal pure-tone thresholds. Moving forward, this new battery of metrics provides a crucial step toward new diagnostics of AN function in humans. NEW & NOTEWORTHY Loss or inactivity of auditory nerve (AN) fibers is thought to contribute to suprathreshold auditory processing deficits, but evidence-based methods to assess these effects are not available. We describe several novel metrics that together may be used to quantify neural synchrony and characterize AN function in humans. PMID- 29187557 TI - The assessment of neurovascular coupling with the Addenbrooke's Cognitive Examination: a functional transcranial Doppler ultrasonographic study. AB - Cerebrovascular dysfunction occurs early in dementia and can be identified by transcranial Doppler ultrasonography (TCD). Few studies have examined cerebral blood flow velocity (CBFv) responses to a detailed cognitive battery. This study aimed to characterize all CBFv responses, and the effect of hemispheric dominance, to the Addenbrooke's Cognitive Examination (ACE-III) in healthy volunteers. Forty volunteers underwent continuous bilateral TCD, beat-to-beat blood pressure (MAP; Finapres), heart rate (HR; electrocardiogram), and end-tidal CO2 (ETCO2; capnography) monitoring. After a 5-min baseline period, all tasks from the ACE-III were performed in 3 sections (A: attention, fluency, memory; B: language; C: visuospatial, memory). Data are population mean normalized percentage (PM%) change from a 20-s baseline period before task initiation. Forty bilateral data sets were obtained (27 women, 37 right-hand dominant). All paradigms produced a sharp increase in CBFv in both dominant (PM% range: 3.29 to 9.70%) and nondominant (PM% range: 4.34 to 11.63%) hemispheres at task initiation, with associated increases in MAP (PM% range: 3.06 to 16.04%). ETCO2 did not differ significantly at task initiation (PM% range: -1.1 to 2.4%, P > 0.05). HR differed significantly across A and C tasks at initiation (PM% range: 1.1 to 2.4%, P < 0.05), but not B tasks. In conclusion, all tasks resulted in increases in CBFv, differing significantly between paradigms. These results require further investigation in a cognitively impaired population. NEW & NOTEWORTHY This study is the first to provide a normative data set of cerebral blood flow velocity (CBFv) responses to a complete cognitive assessment (Addenbrooke's Cognitive Examination, ACE-III) in a large sample ( n = 40) of healthy volunteers. All tasks produced peak and sustained increases in CBFv to different extents. The ACE-III is a feasible tool to assess neurovascular coupling with transcranial Doppler ultrasonography. These data can be used to inform the most appropriate cognitive task to elicit CBFv responses for future studies. PMID- 29187558 TI - Modeling spatial navigation in the presence of dynamic obstacles: a differential games approach. AB - Obstacle circumvention strategies can be shaped by the dynamic interaction of an individual (evader) and an obstacle (pursuer). We have developed a mathematical model with predictive and emergent components, using experimental data from seven healthy young adults walking toward a target while avoiding collision with a stationary or moving obstacle (approaching head-on, or diagonally 30 degrees left or right) in a virtual environment. Two linear properties from the predictive component enable the evader to predict the minimum distance between itself and the obstacle at all times, including the future intersection of trajectories. The emergent component uses the classical differential games model to solve for an optimal circumvention while reaching the target, wherein the locomotor strategy is influenced by the obstacle, target, and the evader velocity. Both model components were fitted to a different set of experimental data obtained from five poststroke and healthy participants to derive the minimum predicted distance (predictive component) and obstacle influence dimensions (emergent component) during circumvention. Minimum predicted distance between evader and pursuer was kept constant when the evader was closest to the obstacle in all participants. Obstacle influence dimensions varied depending on obstacle approach condition and preferred side of circumvention, reflecting differences in locomotor strategies between poststroke and healthy individuals. Additionally, important associations between model outputs and observed experimental outcomes were found. The model, supported by experimental data, suggests that both predictive and emergent processes can shape obstacle circumvention strategies in healthy and poststroke individuals. NEW & NOTEWORTHY Obstacle circumvention during goal-directed locomotion is modeled with a new mathematical approach comprising both predictive and emergent elements. The major novelty is using differential games solutions to illustrate the dynamic interactions between the individual as an evader and the approaching obstacle as a pursuer. The model is supported by experimental evidence that explains the behavior along the continuum of locomotor adaptation displayed by healthy subjects and individuals with stroke. PMID- 29187556 TI - Time course of functional recovery during the first 3 mo after surgical transection and repair of nerves to the feline soleus and lateral gastrocnemius muscles. AB - Locomotion outcomes after peripheral nerve injury and repair in cats have been described in the literature for the period immediately following the injury (muscle denervation period) and then again for an ensuing period of long-term recovery (at 3 mo and longer) resulting in muscle self-reinnervation. Little is known about the changes in muscle activity and walking mechanics during midrecovery, i.e., the early reinnervation period that takes place between 5 and 10 wk of recovery. Here, we investigated hindlimb mechanics and electromyogram (EMG) activity of ankle extensors in six cats during level and slope walking before and every 2 wk thereafter in a 14-wk period of recovery after the soleus (SO) and lateral gastrocnemius (LG) muscle nerves in one hindlimb were surgically transected and repaired. We found that the continued increase in SO and LG EMG magnitudes and corresponding changes in hindlimb mechanics coincided with the formation of neuromuscular synapses revealed in muscle biopsies. Throughout the recovery period, EMG magnitude of SO and LG during the stance phase and the duration of the stance-related activity were load dependent, similar to those in the intact synergistic medial gastrocnemius and plantaris. These results and the fact that EMG activity of ankle extensors and locomotor mechanics during level and upslope walking recovered 14 wk after nerve transection and repair suggest that loss of the stretch reflex in self-reinnervated muscles may be compensated by the recovered force-dependent feedback in self-reinnervated muscles, by increased central drive, and by increased gain in intermuscular motion-dependent pathways from intact ankle extensors. NEW & NOTEWORTHY This study provides new evidence that the timeline for functional recovery of gait after peripheral nerve injury and repair is consistent with the time required for neuromuscular junctions to form and muscles to reach preoperative tensions. Our findings suggest that a permanent loss of autogenic stretch reflex in self-reinnervated muscles may be compensated by recovered intermuscular force-dependent and oligosynaptic length-dependent feedback and central drive to regain adequate locomotor output capabilities during level and upslope walking. PMID- 29187560 TI - Multi-omics Approach Reveals Distinct Differences in Left- and Right-Sided Colon Cancer. AB - Increasing evidence suggests that left-sided colon cancer (LCC) and right-sided colon cancer (RCC) are emerging as two different colorectal cancer types with distinct clinical characteristics. However, the discrepancy in the underlying molecular event between these types of cancer has not been thoroughly elucidated to date and warrants comprehensive investigation. To this end, an integrated dataset from The Cancer Genome Atlas was used to compare and contrast LCC and RCC, covering mutation, DNA methylation, gene expression, and miRNA. Briefly, the signaling pathway cross-talk is more prevalent in RCC than LCC, such as RCC specific PI3K pathway, which often exhibits cross-talk with the RAS and P53 pathways. Meanwhile, methylation signatures revealed that RCC was hypermethylated relative to LCC. In addition, differentially expressed genes (n = 253) and differentially expressed miRNAs (n = 16) were determined between LCC and RCC. Especially for Prostate Cancer Susceptibility Candidate 1 (PRAC1), a gene that was closely associated with hypermethylation, was the top significantly downregulated gene in RCC. Multi-omics comparison of LCC and RCC suggests that there are more aggressive markers in RCC and that tumor heterogeneity occurs within the location-based subtypes of colon cancer. These results clarify the debate regarding the conflicting prognosis between LCC and RCC, as proposed by different studies.Implications: The underlying molecular features present in LCC and RCC identified in this study are beneficial for adopting reasonable therapeutic approaches to prolong overall survival and progression-free survival in colorectal cancer patients.

AB - Hepatocellular carcinoma (HCC) is the most prevalent and highly aggressive liver malignancy with limited therapeutic options. Here, the therapeutic potential of zerumbone, a sesquiterpene derived from the ginger plant Zingiber zerumbet, against HCC was explored. Zerumbone inhibited proliferation and clonogenic survival of HCC cells in a dose-dependent manner by arresting cells at the G2-M phase and inducing apoptosis. To elucidate the underlying molecular mechanisms, a phosphokinase array was performed that showed significant inhibition of the PI3K/AKT/mTOR and STAT3 signaling pathways in zerumbone-treated HCC cells. Gene expression profiling using microarray and analysis of microarray data by Gene Set Enrichment Analysis (GSEA) and Ingenuity Pathway Analysis (IPA) revealed that zerumbone treatment resulted in significant deregulation of genes regulating apoptosis, cell cycle, and metabolism. Indeed, tracing glucose metabolic pathways by growing HCC cells with 13C6-glucose and measuring extracellular and intracellular metabolites by 2D nuclear magnetic resonance (NMR) spectroscopy showed a reduction in glucose consumption and reduced lactate production, suggesting glycolytic inhibition. In addition, zerumbone impeded shunting of glucose-6-phosphate through the pentose phosphate pathway, thereby forcing tumor cells to undergo cell-cycle arrest and apoptosis. Importantly, zerumbone treatment suppressed subcutaneous and orthotopic growth and lung metastasis of HCC xenografts in immunocompromised mice. In conclusion, these findings reveal a novel and potentially effective therapeutic strategy for HCC using a natural product that targets cancer cell metabolism.Implications: Dietary compounds, like zerumbone, that impact cell cycle, apoptosis, and metabolic processes may have therapeutic benefits for HCC patients.

AB - Rapid diagnosis and treatment of an infected joint are paramount in preserving orthopedic function. Here, we present a brief review of the many challenges associated with the diagnosis of both septic arthritis and prosthetic joint infections. We also discuss the many laboratory tests currently available to aid in the accurate diagnosis of joint infection, as well as emerging diagnostics that may have future utility in the diagnosis of these challenging clinical entities. PMID- 29187562 TI - Development and Validation of a Real-Time PCR Assay for Rapid Detection of Candida auris from Surveillance Samples. AB - Candida auris is an emerging multidrug-resistant yeast causing invasive health care-associated infection with high mortality worldwide. Rapid identification of C. auris is of primary importance for the implementation of public health measures to control the spread of infection. To achieve these goals, we developed and validated a TaqMan-based real-time PCR assay targeting the internal transcribed spacer 2 (ITS2) region of the ribosomal gene. The assay was highly specific, reproducible, and sensitive, with the detection limit of 1 C. auris CFU/PCR. The performance of the C. auris real-time PCR assay was evaluated by using 623 surveillance samples, including 365 patient swabs and 258 environmental sponges. Real-time PCR yielded positive results from 49 swab and 58 sponge samples, with 89% and 100% clinical sensitivity with regard to their respective culture-positive results. The real-time PCR also detected C. auris DNA from 1% and 12% of swab and sponge samples with culture-negative results, indicating the presence of dead or culture-impaired C. auris The real-time PCR yielded results within 4 h of sample processing, compared to 4 to 14 days for culture, reducing turnaround time significantly. The new real-time PCR assay allows for accurate and rapid screening of C. auris and can increase effective control and prevention of this emerging multidrug-resistant fungal pathogen in health care facilities. PMID- 29187563 TI - Automated Interpretation of Blood Culture Gram Stains by Use of a Deep Convolutional Neural Network. AB - Microscopic interpretation of stained smears is one of the most operator dependent and time-intensive activities in the clinical microbiology laboratory. Here, we investigated application of an automated image acquisition and convolutional neural network (CNN)-based approach for automated Gram stain classification. Using an automated microscopy platform, uncoverslipped slides were scanned with a 40* dry objective, generating images of sufficient resolution for interpretation. We collected 25,488 images from positive blood culture Gram stains prepared during routine clinical workup. These images were used to generate 100,213 crops containing Gram-positive cocci in clusters, Gram-positive cocci in chains/pairs, Gram-negative rods, or background (no cells). These categories were targeted for proof-of-concept development as they are associated with the majority of bloodstream infections. Our CNN model achieved a classification accuracy of 94.9% on a test set of image crops. Receiver operating characteristic (ROC) curve analysis indicated a robust ability to differentiate between categories with an area under the curve of >0.98 for each. After training and validation, we applied the classification algorithm to new images collected from 189 whole slides without human intervention. Sensitivity and specificity were 98.4% and 75.0% for Gram-positive cocci in chains and pairs, 93.2% and 97.2% for Gram-positive cocci in clusters, and 96.3% and 98.1% for Gram-negative rods. Taken together, our data support a proof of concept for a fully automated classification methodology for blood-culture Gram stains. Importantly, the algorithm was highly adept at identifying image crops with organisms and could be used to present prescreened, classified crops to technologists to accelerate smear review. This concept could potentially be extended to all Gram stain interpretive activities in the clinical laboratory. PMID- 29187564 TI - A Comparison of Aspergillus and Mucorales PCR Testing of Different Bronchoalveolar Lavage Fluid Fractions from Patients with Suspected Invasive Pulmonary Fungal Disease. AB - In patients with hematological malignancies, bronchoalveolar lavage fluid (BALF) specimens are commonly used for the diagnosis of mold infections. However, it is not clear whether the cell pellet (P) or the supernatant fraction (S) of the BALF specimen is optimal for molecular diagnostic testing. Thus, 99 BALF specimens were collected from 96 hematology patients with or without allogeneic hematopoietic stem cell transplant. The cell pellets and supernatants were processed alone and in combination (S/P) for testing by two fungus-specific real time PCR assays compliant with international recommendations. The results achieved with S/P were revealed to be superior in comparison to those achieved with S and P alone, with the use of each single fraction showing a reduced sensitivity for the detection of Aspergillus DNA (82% and 43% for S and P, respectively). In 57% of the samples, testing of the combination of S and P generated a lower quantification cycle value than testing of S or P alone. Molds would have been missed in 5 and 16 out of 28 samples if only S or P, respectively, was analyzed. No sample was positive by testing of S or P only. Similar results were obtained for the detection of Mucorales DNA in BALF specimens (reduced sensitivity of 67% and 50% for S and P, respectively). Study patients were categorized according to the current European Organization for the Research and Treatment of Cancer/Mycoses Study Group classification for invasive fungal disease (IFD), revealing that 35 patients had proven/probable IFD (36%), 47 patients had possible IFD (49%), and 14 patients had undetermined IFD (15%). PMID- 29187565 TI - Evaluation of Oxacillin and Cefoxitin Disk Diffusion and MIC Breakpoints Established by the Clinical and Laboratory Standards Institute for Detection of mecA-Mediated Oxacillin Resistance in Staphylococcus schleiferi. AB - Staphylococcus schleiferi is a beta-hemolytic, coagulase-variable colonizer of small animals that can cause opportunistic infections in humans. In veterinary isolates, the rate of mecA-mediated oxacillin resistance is significant, with reported resistance rates of >39%. The goal of this study was to evaluate oxacillin and cefoxitin disk diffusion (DD) and MIC breakpoints for detection of mecA-mediated oxacillin resistance in 52 human and 38 veterinary isolates of S. schleiferi Isolates were tested on multiple brands of commercial media and according to Clinical and Laboratory Standards Institute (CLSI) methods. Zone diameters and MIC values were interpreted using CLSI breakpoints (CLSI, Performance Standards for Antimicrobial Susceptibility Testing. M100-S27, 2017) for Staphylococcus aureus/Staphylococcus lugdunensis, coagulase-negative staphylococci (CoNS), and Staphylococcus pseudintermedius Results were compared to those of mecA PCR. Twenty-nine of 90 (32%) isolates were mecA positive. Oxacillin inhibition zone sizes and MICs interpreted by S. pseudintermedius breakpoints reliably differentiated mecA-positive and mecA-negative isolates, with a categorical agreement (CA) of 100% and no very major errors (VMEs) or major errors (MEs) for all media. For cefoxitin DD results interpreted using S. aureus/S. lugdunensis and CoNS breakpoints, CA values were 85% and 75%, respectively, and there were 72% and 64% VMEs, respectively, and 0 MEs. For cefoxitin MICs interpreted using S. aureus/S. lugdunensis breakpoints, CA was 81%, and there were 60% VMEs and no MEs. Our data demonstrate that oxacillin DD or MIC testing methods using the current S. pseudintermedius breakpoints reliably identify mecA-mediated oxacillin resistance in S. schleiferi, while cefoxitin DD and MIC testing methods perform poorly. PMID- 29187566 TI - Stage-Specific Gene Profiling of Germinal Cells Helps Delineate the Mitosis/Meiosis Transition. AB - In flowering plants, germ lines are induced from somatic meristems within reproductive organs. Within anthers, germinal cell initials first undergo several rounds of mitotic proliferation before synchronously entering meiosis. Our understanding of the progression and the molecular basis of this mitosis to meiosis transition is still limited. Taking advantage of the correlation between anther length and premeiotic germinal cell development in maize (Zea mays), we studied the transcriptome dynamics of germinal cells at three sequential stages, mitotic archesporial cells, enlarging pollen mother cells at the premeiosis interphase, and pollen mother cells at the early prophase of meiosis, using laser microdissection-based expression profiling. Our analysis showed that cells undergoing the mitosis-meiosis switch exhibit robust transcriptional changes. The three stages are distinguished by the expression of genes encoding transcription factor subsets, meiotic chromosome recombination proteins, and distinct E3 ubiquitin ligases, respectively. The transcription level of genes encoding protein turnover machinery was significantly higher in these three stages of germinal cells than in mature pollen, parenchyma cells, or seedlings. Our experimental results further indicate that many meiotic genes are not only transcribed, but also translated prior to meiosis. We suggest that the enlarging pollen mother cells stage represents a crucial turning point from mitosis to meiosis for developing germinal cells. PMID- 29187567 TI - Linking PHYTOCHROME-INTERACTING FACTOR to Histone Modification in Plant Shade Avoidance. AB - Shade avoidance syndrome (SAS) allows a plant grown in a densely populated environment to maximize opportunities to access to sunlight. Although it is well established that SAS is accompanied by gene expression changes, the underlying molecular mechanism needs to be elucidated. Here, we identify the H3K4me3/H3K36me3-binding proteins, Morf Related Gene (MRG) group proteins MRG1 and MRG2, as positive regulators of shade-induced hypocotyl elongation in Arabidopsis (Arabidopsis thaliana). MRG2 binds PHYTOCHROME-INTERACTING FACTOR7 (PIF7) and regulates the expression of several common downstream target genes, including YUCCA8 and IAA19 involved in the auxin biosynthesis or response pathway and PRE1 involved in brassinosteroid regulation of cell elongation. In response to shade, PIF7 and MRG2 are enriched at the promoter and gene-body regions and are necessary for increase of histone H4 and H3 acetylation to promote target gene expression. Our study uncovers a mechanism in which the shade-responsive factor PIF7 recruits MRG1/MRG2 that binds H3K4me3/H3K36me3 and brings histone acetylases to induce histone acetylations to promote expression of shade responsive genes, providing thus a molecular mechanistic link coupling the environmental light to epigenetic modification in regulation of hypocotyl elongation in plant SAS. PMID- 29187569 TI - Dynamics of Ethylene Production in Response to Compatible Nod Factor. AB - Establishment of symbiotic nitrogen-fixation in legumes is regulated by the plant hormone ethylene, but it has remained unclear whether and how its biosynthesis is regulated by the symbiotic pathway. We established a sensitive ethylene detection system for Lotus japonicus and found that ethylene production increased as early as 6 hours after inoculation with Mesorhizobium loti This ethylene response was dependent on Nod factor production by compatible rhizobia. Analyses of nodulation mutants showed that perception of Nod factor was required for ethylene emission, while downstream transcription factors including CYCLOPS, NIN, and ERN1 were not required for this response. Activation of the nodulation signaling pathway in spontaneously nodulating mutants was also sufficient to elevate ethylene production. Ethylene signaling is controlled by EIN2, which is duplicated in L. japonicus We obtained a L. japonicus Ljein2a Ljein2b double mutant that exhibits complete ethylene insensitivity and confirms that these two genes act redundantly in ethylene signaling. Consistent with this redundancy, both LjEin2a and LjEin2b are required for negative regulation of nodulation and Ljein2a Ljein2b double mutants are hypernodulating and hyperinfected. We also identified an unexpected role for ethylene in the onset of nitrogen fixation, with the Ljein2a Ljein2b double mutant showing severely reduced nitrogen fixation. These results demonstrate that ethylene production is an early and sustained nodulation response that acts at multiple stages to regulate infection, nodule organogenesis, and nitrogen fixation in L. japonicus. PMID- 29187568 TI - Molecular Mechanisms of Photoadaptation of Photosystem I Supercomplex from an Evolutionary Cyanobacterial/Algal Intermediate. AB - The monomeric photosystem I-light-harvesting antenna complex I (PSI-LHCI) supercomplex from the extremophilic red alga Cyanidioschyzon merolae represents an intermediate evolutionary link between the cyanobacterial PSI reaction center and its green algal/higher plant counterpart. We show that the C. merolae PSI LHCI supercomplex is characterized by robustness in various extreme conditions. By a combination of biochemical, spectroscopic, mass spectrometry, and electron microscopy/single particle analyses, we dissected three molecular mechanisms underlying the inherent robustness of the C. merolae PSI-LHCI supercomplex: (1) the accumulation of photoprotective zeaxanthin in the LHCI antenna and the PSI reaction center; (2) structural remodeling of the LHCI antenna and adjustment of the effective absorption cross section; and (3) dynamic readjustment of the stoichiometry of the two PSI-LHCI isomers and changes in the oligomeric state of the PSI-LHCI supercomplex, accompanied by dissociation of the PsaK core subunit. We show that the largest low light-treated C. merolae PSI-LHCI supercomplex can bind up to eight Lhcr antenna subunits, which are organized as two rows on the PsaF/PsaJ side of the core complex. Under our experimental conditions, we found no evidence of functional coupling of the phycobilisomes with the PSI-LHCI supercomplex purified from various light conditions, suggesting that the putative association of this antenna with the PSI supercomplex is absent or may be lost during the purification procedure. PMID- 29187570 TI - The Transcription Factor COL12 Is a Substrate of the COP1/SPA E3 Ligase and Regulates Flowering Time and Plant Architecture. AB - The ambient light environment controls many aspects of plant development throughout a plant's life cycle. Such complex control is achieved because a key repressor of light signaling, the Arabidopsis (Arabidopsis thaliana) COP1/SPA E3 ubiquitin ligase causes the degradation of multiple regulators of endogenous developmental pathways. This includes the CONSTANS (CO) transcription factor that is responsible for photoperiodic control of flowering time. There are 16 CO-like proteins whose functions are only partly understood. Here, we show that 14 CO like (COL) proteins bind CONSTITUTIVELY PHOTOMORPHOGENIC1 (COP1) and SUPPRESSOR OF PHYTOCHROME A-105 (SPA)1 in vitro. We subsequently focused on COL12 and show that COL12 binds COP1 and SPA proteins in vivo. The COL12 protein is degraded in darkness in a COP1-dependent fashion, indicating that COL12 is a substrate of the COP1/SPA ubiquitin ligase. Overexpression of COL12 causes late flowering specifically in long day conditions by decreasing the expression of FLOWERING LOCUS T This phenotype is genetically dependent on CO. Consistent with this finding, COL12 physically interacts with CO in vivo, suggesting that COL12 represses flowering by inhibiting CO protein function. We show that COL12 overexpression did not alter CO protein stability. It is therefore likely that COL12 represses the activity of CO rather than CO levels. Overexpression of COL12 also affects plant architecture by increasing the number of rosette branches and reducing inflorescence height. These phenotypes are CO independent. Hence, we suggest that COL12 affects plant development through CO-dependent and CO independent mechanisms. PMID- 29187572 TI - The Scientific Society Publisher Alliance delivers an important message.

PMID- 29187571 TI - The Brassicaceae Family Displays Divergent, Shoot-Skewed NLR Resistance Gene Expression. AB - Nucleotide-binding site leucine-rich repeat resistance genes (NLRs) allow plants to detect microbial effectors. We hypothesized that NLR expression patterns could reflect organ-specific differences in effector challenge and tested this by carrying out a meta-analysis of expression data for 1,235 NLRs from nine plant species. We found stable NLR root/shoot expression ratios within species, suggesting organ-specific hardwiring of NLR expression patterns in anticipation of distinct challenges. Most monocot and dicot plant species preferentially expressed NLRs in roots. In contrast, Brassicaceae species, including oilseed rape (Brassica napus) and the model plant Arabidopsis (Arabidopsis thaliana), were unique in showing NLR expression skewed toward the shoot across multiple phylogenetically distinct groups of NLRs. The Brassicaceae are also outliers in the sense that they have lost the common symbiosis signaling pathway, which enables intracellular infection by root symbionts. While it is unclear if these two events are related, the NLR expression shift identified here suggests that the Brassicaceae may have evolved unique pattern-recognition receptors and antimicrobial root metabolites to substitute for NLR protection. Such innovations in root protection could potentially be exploited in crop rotation schemes or for enhancing root defense systems of non-Brassicaceae crops. PMID- 29187574 TI - Stu2 uses a 15-nm parallel coiled coil for kinetochore localization and concomitant regulation of the mitotic spindle. AB - XMAP215/Dis1 family proteins are potent microtubule polymerases, critical for mitotic spindle structure and dynamics. While microtubule polymerase activity is driven by an N-terminal tumor overexpressed gene (TOG) domain array, proper cellular localization is a requisite for full activity and is mediated by a C terminal domain. Structural insight into the C-terminal domain's architecture and localization mechanism remain outstanding. We present the crystal structure of the Saccharomyces cerevisiae Stu2 C-terminal domain, revealing a 15-nm parallel homodimeric coiled coil. The parallel architecture of the coiled coil has mechanistic implications for the arrangement of the homodimer's N-terminal TOG domains during microtubule polymerization. The coiled coil has two spatially distinct conserved regions: CRI and CRII. Mutations in CRI and CRII perturb the distribution and localization of Stu2 along the mitotic spindle and yield defects in spindle morphology including increased frequencies of mispositioned and fragmented spindles. Collectively, these data highlight roles for the Stu2 dimerization domain as a scaffold for factor binding that optimally positions Stu2 on the mitotic spindle to promote proper spindle structure and dynamics. PMID- 29187575 TI - A role for the Smc3 hinge domain in the maintenance of sister chromatid cohesion. AB - Cohesin is a conserved protein complex required for sister chromatid cohesion, chromosome condensation, DNA damage repair, and regulation of transcription. Although cohesin functions to tether DNA duplexes, the contribution of its individual domains to this activity remains poorly understood. We interrogated the Smc3p subunit of cohesin by random insertion mutagenesis. Analysis of a mutant in the Smc3p hinge revealed an unexpected role for this domain in cohesion maintenance and condensation. Further investigation revealed that the Smc3p hinge functions at a step following cohesin's stable binding to chromosomes and independently of Smc3p's regulation by the Eco1p acetyltransferase. Hinge mutant phenotypes resemble loss of Pds5p, which binds opposite the hinge near Smc3p's head domain. We propose that a specific conformation of the Smc3p hinge and Pds5p cooperate to promote cohesion maintenance and condensation.

AB - Host cell invasion is an indispensable step for a successful infection by intracellular pathogens. Recent studies identified pathogen-induced host cell plasma membrane perforation as a novel mechanism used by diverse pathogens (Trypanosoma cruzi, Listeria monocytogenes, and adenovirus) to promote their internalization into target cells. It was concluded that T. cruzi and adenovirus damage the host cell plasma membrane to hijack the endocytic-dependent membrane resealing machinery, thereby invading the host cell. We studied L. monocytogenes and its secreted pore-forming toxin listeriolysin O (LLO) to identify key signaling events activated upon plasma membrane perforation that lead to bacterial internalization. Using various approaches, including fluorescence resonance energy transfer imaging, we found that the influx of extracellular Ca2+ subsequent to LLO-mediated plasma membrane perforation is required for the activation of a conventional protein kinase C (cPKC). cPKC is positioned upstream of Rac1 and the Arp2/3 complex, which activation leads to F-actin--dependent bacterial internalization. Inhibition of this pathway did not prevent membrane resealing, revealing that perforation-dependent L. monocytogenes endocytosis is distinct from the resealing machinery. These studies identified the LLO-dependent endocytic pathway of L. monocytogenes and support a novel model for pathogen uptake promoted by plasma membrane injury that is independent of membrane resealing.

AB - The cleavage furrow in Xenopus zygotes is positioned by two large microtubule asters that grow out from the poles of the first mitotic spindle. Where these asters meet at the midplane, they assemble a disk-shaped interaction zone consisting of anti-parallel microtubule bundles coated with chromosome passenger complex (CPC) and centralspindlin that instructs the cleavage furrow. Here we investigate the mechanism that keeps the two asters separate and forms a distinct boundary between them, focusing on the conserved cytokinesis midzone proteins Prc1 and Kif4A. Prc1E, the egg orthologue of Prc1, and Kif4A were recruited to anti-parallel bundles at interaction zones between asters in Xenopus egg extracts. Prc1E was required for Kif4A recruitment but not vice versa. Microtubule plus-end growth slowed and terminated preferentially within interaction zones, resulting in a block to interpenetration that depended on both Prc1E and Kif4A. Unexpectedly, Prc1E and Kif4A were also required for radial order of large asters growing in isolation, apparently to compensate for the direction-randomizing influence of nucleation away from centrosomes. We propose that Prc1E and Kif4, together with catastrophe factors, promote "anti-parallel pruning" that enforces radial organization within asters and generates boundaries to microtubule growth between asters. PMID- 29187578 TI - Stu2 acts as a microtubule destabilizer in metaphase budding yeast spindles. AB - The microtubule-associated protein Stu2 (XMAP215) has the remarkable ability to act either as a polymerase or as a destabilizer of the microtubule plus end. In budding yeast, it is required for the dynamicity of spindle microtubules and also for kinetochore force generation. To understand how Stu2 contributes to these distinct activities, we analyzed the contributions of its functional domains to its localization and function. We find that Stu2 colocalizes with kinetochores using its TOG domains, which bind GTP-tubulin, a coiled-coil homodimerization domain, and a domain that interacts with plus-end interacting proteins. Stu2 localization is also promoted by phosphorylation at a putative CDK1 phosphorylation site located within its microtubule-binding basic patch. Surprisingly, however, we find that kinetochore force generation is uncorrelated with the amount of kinetochore-colocalized Stu2. These and other data imply that Stu2 colocalizes with kinetochores by recognizing growing microtubule plus ends within yeast kinetochores. We propose that Stu2 destabilizes these plus ends to indirectly contribute to the "catch-bond" activity of the kinetochores. PMID- 29187579 TI - Urinary Tract Infection Antibiotic Trial Study Design: A Systematic Review. AB - CONTEXT: Urinary tract infections (UTIs) represent common bacterial infections in children. No guidance on the conduct of pediatric febrile UTI clinical trials (CTs) exist. OBJECTIVE: To assess the criteria used for patient selection and the efficacy end points in febrile pediatric UTI CTs. DATA SOURCES: Medline, Embase, Cochrane central databases, and clinicaltrials.gov were searched between January 1, 1990, and November 24, 2016. STUDY SELECTION: We combined Medical Subject Headings terms and free-text terms for "urinary tract infections" and "therapeutics" and "clinical trials" in children (0-18 years), identifying 3086 articles. DATA EXTRACTION: Two independent reviewers assessed study quality and performed data extraction. RESULTS: We included 40 CTs in which a total of 4381 cases of pediatric UTIs were investigated. Positive urine culture results and fever were the most common inclusion criteria (93% and 78%, respectively). Urine sampling method, pyuria, and colony thresholds were highly variable. Clinical and microbiological end points were assessed in 88% and 93% of the studies, respectively. Timing for end point assessment was highly variable, and only 3 studies (17%) out of the 18 performed after the Food and Drug Administration 1998 guidance publication assessed primary and secondary end points consistently with this guidance. LIMITATIONS: Our limitations included a mixed population of healthy children and children with an underlying condition. In 6 trials, researchers studied a subgroup of patients with afebrile UTI. CONCLUSIONS: We observed a wide variability in the microbiological inclusion criteria and the timing for end point assessment. The available guidance for adults appear not to be used by pediatricians and do not seem applicable to the childhood UTI. A harmonized design for pediatric UTIs CT is necessary. PMID- 29187580 TI - Computer-Aided Recognition of Facial Attributes for Fetal Alcohol Spectrum Disorders. AB - OBJECTIVES: To compare the detection of facial attributes by computer-based facial recognition software of 2-D images against standard, manual examination in fetal alcohol spectrum disorders (FASD). METHODS: Participants were gathered from the Fetal Alcohol Syndrome Epidemiology Research database. Standard frontal and oblique photographs of children were obtained during a manual, in-person dysmorphology assessment. Images were submitted for facial analysis conducted by the facial dysmorphology novel analysis technology (an automated system), which assesses ratios of measurements between various facial landmarks to determine the presence of dysmorphic features. Manual blinded dysmorphology assessments were compared with those obtained via the computer-aided system. RESULTS: Areas under the curve values for individual receiver-operating characteristic curves revealed the computer-aided system (0.88 +/- 0.02) to be comparable to the manual method (0.86 +/- 0.03) in detecting patients with FASD. Interestingly, cases of alcohol related neurodevelopmental disorder (ARND) were identified more efficiently by the computer-aided system (0.84 +/- 0.07) in comparison to the manual method (0.74 +/- 0.04). A facial gestalt analysis of patients with ARND also identified more generalized facial findings compared to the cardinal facial features seen in more severe forms of FASD. CONCLUSIONS: We found there was an increased diagnostic accuracy for ARND via our computer-aided method. As this category has been historically difficult to diagnose, we believe our experiment demonstrates that facial dysmorphology novel analysis technology can potentially improve ARND diagnosis by introducing a standardized metric for recognizing FASD-associated facial anomalies. Earlier recognition of these patients will lead to earlier intervention with improved patient outcomes. PMID- 29187581 TI - Randomized Trials in Children With UTI. PMID- 29187582 TI - Zhenbao pill protects against acute spinal cord injury via miR-146a-5p regulating the expression of GPR17. AB - The aim of the present study was to observe the effect of zhenbao pill on the motor function of acute spinal cord injury (ASCI) rats and the molecular mechanisms involving miR-146a-5p and G-protein-coupled receptor 17 (GPR17). ASCI rat model was established by modified Allen method, and then the rats were divided into three groups. SH-SY5Y cells were cultured overnight in hypoxia condition and transfected with miR-146a-5p mimic or miR-146a-5p inhibitor. The hind limb motor function of the rats was evaluated by Basso, Beattie, Bresnahan (BBB) scoring system. Quantitative real-time PCR (qRT-PCR) and Western blot were used to detect the expression of miR-146a-5p, GPR17, inducible nitric oxide synthase (iNOS), interleukin 1beta (IL-1beta), and tumor necrosis factor alpha (TNF-alpha). Neuronal apoptosis was measured using flow cytometry assay. Luciferase reporter assay was performed to determine the regulation of miR-146a 5p on GPR17. Zhenbao pill could enhance hind limb motor function and attenuate the inflammatory response caused by ASCI. Moreover, zhenbao pill increased the level of miR-146a-5p and decreased GPR17 expression in vivo and in vitro Bioinformatics software predicted that GPR17 3'-UTR had a binding site with miR 146a-5p Luciferase reporter assay showed that miR-146a-5p had a negative regulatory effect on GPR17 expression. Knockdown of miR-146a-5p could reverse the effect of zhenbao pill on the up-regulation of GPR17 induced by hypoxia, reversed the inhibitory effect of zhenbao pill on the cell apoptosis induced by hypoxia and the recovery of zhenbao pill on hind limb motor function in ASCI rats. Zhenbao pill could inhibit neuronal apoptosis by regulating miR-146a-5p/GPR17 expression, and then promoting the recovery of spinal cord function. PMID- 29187584 TI - A novel bispecific c-MET/CTLA-4 antibody targeting lung cancer stem cell-like cells with therapeutic potential in human non-small cell lung cancer. AB - A novel paradigm in tumor biology suggests that non-small cell lung cancer (NSCLC) growth is driven by lung cancer stem cell-like cells (LCSCs), but here are still not any effective strategies to remove LCSCs. The bispecific antibody is a novel antibody, which can target two different antigens and mediate specific killing effects by selectively redirecting effector cells to the target cells. Here, we designed and synthesized a new bispecific antibody (BsAb), BsAb-5, that can target cellular-mesenchymal to epithelial transition factor (c-MET) and cytotoxic T-lymphocyte associated protein 4 (CTLA-4) in CD166+ LCSCs with high affinity and specificity, for the first time. We showed that BsAb-5 could inhibit hepatocyte growth factor (HGF)-mediated tumor development, including proliferation, migration, and apoptosis, serving as an inhibitory c-MET antibody. Moreover, we demonstrated that mechanisms responsible for BsAb-5 in CD166+ LCSCs included inducing c-MET degradation and inhibition HGF-stimulated c-MET-Notch pathway by using AdHGF infection, nuclei location and western-blot assays. In vivo, xenograft analysis revealed that mice on BsAb-5 group showed significantly reduced tumor volume. At the meantime, the observed anti-tumor effects of BsAb-5 were dependent on considerably suppressing Tregs and up-regulating effector T cells. On the basis of these results, we have identified a potential bispecific antibody drug, which can effectively target c-MET and CTLA-4 in CD166+ LCSCs for the treatment of human NSCLC. PMID- 29187583 TI - MiR-375 attenuates injury of cerebral ischemia/reperfusion via targetting Ctgf. AB - Ischemic stroke is the leading cause of disability and deaths worldwide. MiRNAs have been shown to play an important role in development and pathogenesis of the nervous system. However, the precise function and mechanism of miRNAs are not fully understood in the brain injury induced by ischemia/reperfusion (I/R). Herein, our study showed that miR-375 expression was significantly down-regulated in the rat I/R brain. With the in vivo and in vitro I/R stroke models, we found that miR-375 mimic provides significant protection from injury to cerebral I/R, which is reflected by reduced infarct volumes and cell apoptosis, and increased proliferation and migration of PC12 cells. Mechanistically, our findings showed that miR-375 binds to 3'-UTR region of Ctgf mRNA, subsequently leading to the decreased expression of Ctgf in the I/R brain. Furthermore, we showed that miR 375/Ctgf-mediated protective effects are associated with p21/PI3K/Akt signaling pathways. Our findings thus provide a new insight into the mechanism of cerebral I/R injury and pave a potential new way for the therapy of cerebral I/R injury. PMID- 29187585 TI - miR-27b promotes type II collagen expression by targetting peroxisome proliferator-activated receptor-gamma2 during rat articular chondrocyte differentiation. AB - MicroRNAs (miRNAs) play an essential role in articular cartilage development and growth. However, the exact mechanisms involved in this process remain unknown. In the present study, we investigated the biological functions of miR-27b during hypertrophic differentiation of rat articular chondrocytes. Based on in situ hybridization and immunohistochemistry, we report that miR-27b expression is reduced in the hypertrophic zone of articular cartilage, but expression of peroxisome proliferator-activated receptor gamma (Ppargamma) is increased. Dual luciferase reporter gene assay and Western blot analysis demonstrated that Ppargamma2 is a target of miR-27b Overexpression of miR-27b inhibited expression of Ppargamma2, as well as type X collagen (Col10a1) and matrix metalloproteinase 13 (Mmp13), while significantly promoting the expression of Sex-determining Region-box 9 (Sox9) and type II collagen (Col2a1) at both the mRNA and protein levels. Rosiglitazone, a Ppargamma agonist, suppressed Col2a1 expression, while promoting expression of runt-related transcription factor 2 (Runx2) and Col10a1 in a concentration-dependent manner. siRNA-mediated knockdown of Ppargamma2 caused an increase in protein levels of Col2a1. The present study demonstrates that miR-27b regulates chondrocyte hypertrophy in part by targetting Ppargamma2, and that miR-27b may have important therapeutic implications in cartilage diseases. PMID- 29187586 TI - Live Attenuated Leishmania donovani Centrin Gene-Deleted Parasites Induce IL-23 Dependent IL-17-Protective Immune Response against Visceral Leishmaniasis in a Murine Model. AB - No vaccine exists against visceral leishmaniasis. To develop effective vaccines, we have previously reported protective role of live attenuated centrin gene deleted Leishmania donovani (LdCen-/- ) parasites through induction of Th1 type immune response in mice, hamsters, and dogs. In this study, we specifically explored the role of Th17 cells in LdCen-/- -induced host protection in mice. Our results showed that compared with wild-type L. donovani infection, LdCen-/- parasites induce significantly higher expression of Th17 differentiation cytokines in splenic dendritic cells. There was also induction of IL-17 and its promoting cytokines in total splenocytes and in both CD4 and CD8 T cells following immunization with LdCen-/- Upon challenge with wild-type parasites, IL 17 and its differentiating cytokines were significantly higher in LdCen-/- immunized mice compared with nonimmunized mice that resulted in parasite control. Alongside IL-17 induction, we observed induction of IFN-gamma-producing Th1 cells as reported earlier. However, Th17 cells are generated before Th1 cells. Neutralization of either IL-17 or IFN-gamma abrogated LdCen-/- -induced host protection further confirming the essential role of Th17 along with Th1 cytokines in host protection. Treatment with recombinant IL-23, which is required for stabilization and maintenance of IL-17, heightened Th17, and Tc17 responses in immunized mice splenocytes. In contrast, Th17 response was absent in immunized IL 23R-/- mice that failed to induce protection upon virulent Leishmania challenge suggesting that IL-23 plays an essential role in IL-17-mediated protection by LdCen-/- parasites. This study unveiled the role of IL-23-dependent IL-17 induction in LdCen-/- parasite-induced immunity and subsequent protection against visceral leishmaniasis. PMID- 29187587 TI - Modulation of the Alternative Pathway of Complement by Murine Factor H-Related Proteins. AB - Factor H (FH) is a key alternative pathway regulator that controls complement activation both in the fluid phase and on specific cell surfaces, thus allowing the innate immune response to discriminate between self and foreign pathogens. However, the interrelationships between FH and a group of closely related molecules, designated the FH-related (FHR) proteins, are currently not well understood. Whereas some studies have suggested that human FHR proteins possess complement regulatory abilities, recent studies have shown that FHR proteins are potent deregulators. Furthermore, the roles of the FHR proteins have not been explored in any in vivo models of inflammatory disease. In this study, we report the cloning and expression of recombinant mouse FH and three FHR proteins (FHR proteins A-C). Results from functional assays show that FHR-A and FHR-B proteins antagonize the protective function of FH in sheep erythrocyte hemolytic assays and increase cell-surface C3b deposition on a mouse kidney proximal tubular cell line (TEC) and a human retinal pigment epithelial cell line (ARPE-19). We also report apparent KD values for the binding interaction of mouse C3d with mouse FH (3.85 MUM), FHR-A (136 nM), FHR-B (546 nM), and FHR-C (1.04 MUM), which directly correlate with results from functional assays. Collectively, our work suggests that similar to their human counterparts, a subset of mouse FHR proteins have an important modulatory role in complement activation. Further work is warranted to define the in vivo context-dependent roles of these proteins and determine whether FHR proteins are suitable therapeutic targets for the treatment of complement-driven diseases. PMID- 29187588 TI - CXCR3/CXCL10 Axis Shapes Tissue Distribution of Memory Phenotype CD8+ T Cells in Nonimmunized Mice. AB - The preimmune repertoire consists of mature T lymphocytes that have not yet been stimulated in the periphery. Memory phenotype (MP) cells have been reported as part of the preimmune repertoire (i.e., T cells bearing memory markers despite lack of engagement with cognate Ag); however, little is known about their trafficking and function. In this study, we hypothesized that MP cells, naive to TCR stimulation, constitute a transient population that traffics to tissues during development. Using mutant and transgenic animals with a monospecific TCR, we discovered increased numbers of MP CD8+ T cells circulating in nonimmunized Cxcr3-/- and Cxcl10-/- mice compared with wild-type animals. Phenotypic differences included decreased numbers of preimmune MP Ag-specific T cells in the skin and thymus and a distinct pattern of activation upon TCR engagement. Our results show for the first time, to our knowledge, an important role for CXCR3 and CXCL10 in the tissue distribution of preimmune MP cells. PMID- 29187589 TI - STAT5B: A Differential Regulator of the Life and Death of CD4+ Effector Memory T Cells. AB - Understanding the control of Ag restimulation-induced T cell death (RICD), especially in cancer immunotherapy, where highly proliferating T cells will encounter potentially large amounts of tumor Ags, is important now more than ever. It has been known that growth cytokines make T cells susceptible to RICD, but the precise molecular mediators that govern this in T cell subsets is unknown until now. STAT proteins are a family of transcription factors that regulate gene expression programs underlying key immunological processes. In particular, STAT5 is known to favor the generation and survival of memory T cells. In this study, we report an unexpected role for STAT5 signaling in the death of effector memory T (TEM) cells in mice and humans. TEM cell death was prevented with neutralizing anti-IL-2 Ab or STAT5/JAK3 inhibitors, indicating that STAT5 signaling drives RICD in TEM cells. Moreover, we identified a unique patient with a heterozygous missense mutation in the coiled-coil domain of STAT5B that presented with autoimmune lymphoproliferative syndrome-like features. Similar to Stat5b-/- mice, this patient exhibited increased CD4+ TEM cells in the peripheral blood. The mutant STAT5B protein dominantly interfered with STAT5-driven transcriptional activity, leading to global downregulation of STAT5-regulated genes in patient T cells upon IL-2 stimulation. Notably, CD4+ TEM cells from the patient were strikingly resistant to cell death by in vitro TCR restimulation, a finding that was recapitulated in Stat5b-/- mice. Hence, STAT5B is a crucial regulator of RICD in memory T cells in mice and humans. PMID- 29187590 TI - Selective Cannabinoid 2 Receptor Stimulation Reduces Tubular Epithelial Cell Damage after Renal Ischemia-Reperfusion Injury. AB - Ischemia-reperfusion injury (IRI) is a common cause of acute kidney injury (AKI), which is an increasing problem in the clinic and has been associated with elevated rates of mortality. Therapies to treat AKI are currently not available, so identification of new targets that can be modulated to ameliorate renal damage upon diagnosis of AKI is essential. In this study, a novel cannabinoid receptor 2 (CB2) agonist, SMM-295 [3'-methyl-4-(2-(thiophen-2-yl)propan-2-yl)biphenyl-2,6 diol], was designed, synthesized, and tested in vitro and in silico. Molecular docking of SMM-295 into a CB2 active-state homology model showed that SMM-295 interacts well with key amino acids to stabilize the active state. In human embryonic kidney 293 cells, SMM-295 was capable of reducing cAMP production with 66-fold selectivity for CB2 versus cannabinoid receptor 1 and dose-dependently increased mitogen-activated protein kinase and Akt phosphorylation. In vivo testing of the CB2 agonist was performed using a mouse model of bilateral IRI, which is a common model to mimic human AKI, where SMM-295 was immediately administered upon reperfusion of the kidneys after the ischemia episode. Histologic damage assessment 48 hours after reperfusion demonstrated reduced tubular damage in the presence of SMM-295. This was consistent with reduced plasma markers of renal dysfunction (i.e., creatinine and neutrophil gelatinase associated lipocalin) in SMM-295-treated mice. Mechanistically, kidneys treated with SMM-295 were shown to have elevated activation of Akt with reduced terminal deoxynucleotidyl transferase-mediated digoxigenin-deoxyuridine nick-end labeling (TUNEL)-positive cells compared with vehicle-treated kidneys after IRI. These data suggest that selective CB2 receptor activation could be a potential therapeutic target in the treatment of AKI. PMID- 29187592 TI - Heterogeneity of respiratory disease in children and young adults with sickle cell disease. AB - To detect and characterise different phenotypes of respiratory disease in children and young adults with sickle cell disease (SCD), 11 lung function and haematological biomarkers were analysed using k-means cluster analysis in a cohort of 114 subjects with SCD aged between 5 and 27 years. Three clusters were detected: cluster 1 had elevated pulmonary capillary blood volume, mixed obstructive/restrictive lung disease, hypoxia and moderately severe anaemia; cluster 2 were older patients with restrictive lung disease; and cluster 3 were younger patients with obstructive lung disease, elevated serum lactate dehydrogenase and bronchodilator reversibility. These results may inform more personalised management strategies to improve outcomes. PMID- 29187593 TI - Ghost of chest drain past. PMID- 29187591 TI - MicroRNA dynamics at the onset of primordial germ and somatic cell sex differentiation during mouse embryonic gonad development. AB - In mammals, commitment and specification of germ cell lines involves complex programs that include sex differentiation, control of proliferation, and meiotic initiation. Regulation of these processes is genetically controlled by fine-tuned mechanisms of gene regulation in which microRNAs (miRNAs) are involved. We have characterized, by small-RNA-seq and bioinformatics analyses, the miRNA expression patterns of male and female mouse primordial germ cells (PGCs) and gonadal somatic cells at embryonic stages E11.5, E12.5, and E13.5. Differential expression analyses revealed differences in the regulation of key miRNA clusters such as miR-199-214, miR-182-183-96, and miR-34c-5p, whose targets have defined roles during gonadal sexual determination in both germ and somatic cells. Extensive analyses of miRNA sequences revealed an increase in noncanonical isoforms on PGCs at E12.5 and dramatic changes of 3' isomiR expression and 3' nontemplate nucleotide additions in female PGCs at E13.5. Additionally, RT-qPCR analyses of genes encoding proteins involved in miRNA biogenesis and 3' nucleotide addition uncovered sexually and developmentally specific expression, characterized by the decay of Drosha, Dgcr8, and Xpo5 expression along gonadal development. These results demonstrate that miRNAs, their isomiRs, and miRNA machinery are differentially regulated and participate actively in gonadal sexual differentiation in both PGCs and gonadal somatic cells. PMID- 29187594 TI - Plasma urate, lung function and chronic obstructive pulmonary disease: a Mendelian randomisation study in 114 979 individuals from the general population. AB - BACKGROUND: Urate is a strong antioxidant in plasma and may protect against lung function impairment. We tested the hypothesis that high plasma urate is causally associated with better lung function and low risk of respiratory symptoms and COPD. METHODS: We measured lung function and plasma urate in 114 979 individuals from the Copenhagen City Heart Study and the Copenhagen General Population Study and genotyped for SLC2A9 rs7442295 and ABCG2 rs2231142 variants, previously associated with high plasma urate, in 110 152 individuals. RESULTS: In the two studies combined, multivariable-adjusted 100 umol/L higher plasma urate was associated with -1.54% (95% CI -1.67 to -1.40) lower FEV1 % predicted and -1.57% (95% CI -1.69 to -1.44) lower FVC % predicted observationally; the corresponding estimates for genetically determined 100 umol/L higher plasma urate were -0.46% (95% CI -1.17 to 0.25) and -0.40% (95% CI -1.03 to 0.23). High plasma urate was also associated with higher risk of respiratory symptoms; however, genetically determined high plasma urate was not associated with respiratory symptoms. Finally, we identified 14 151 individuals with COPD and found ORs of 1.08 (95% CI 1.06 to 1.11) for COPD observationally and 1.01 (95% CI 0.88 to 1.15) genetically per 100 umol/L higher plasma urate. CONCLUSION: High plasma urate was associated with worse lung function and higher risk of respiratory symptoms and COPD in observational analyses; however, genetically high plasma urate was not associated with any of these outcomes. Thus, our data do not support a direct causal relationship. PMID- 29187595 TI - Ubiquitin signaling and autophagy. AB - Ubiquitination is a widespread post-translational modification that controls multiple steps in autophagy, a major lysosome-mediated intracellular degradation pathway. A variety of ubiquitin chains are attached as selective labels on protein aggregates and dysfunctional organelles, thus promoting their autophagy dependent degradation. Moreover, ubiquitin modification of autophagy regulatory components is essential to positively or negatively regulate autophagy flux in both non-selective and selective pathways. We review the current findings that elucidate the components, timing, and kinetics of the multivalent role of ubiquitin signals in control of amplitude and selectivity of autophagy pathways as well as their impact on the development of human diseases. PMID- 29187596 TI - The dUTPase of white spot syndrome virus assembles its active sites in a noncanonical manner. AB - dUTPases are essential enzymes for maintaining genome integrity and have recently been shown to play moonlighting roles when containing extra sequences. Interestingly, the trimeric dUTPase of white spot syndrome virus (wDUT) harbors a sequence insert at the position preceding the C-terminal catalytic motif V (pre-V insert), rarely seen in other dUTPases. However, whether this extra sequence endows wDUT with additional properties is unknown. Herein, we present the crystal structures of wDUT in both ligand-free and ligand-bound forms. We observed that the pre-V insert in wDUT forms an unusual beta-hairpin structure in the domain swapping region and thereby facilitates a unique orientation of the adjacent C terminal segment, positioning the catalytic motif V onto the active site of its own subunit instead of a third subunit. Consequently, wDUT employs two-subunit active sites, unlike the widely accepted paradigm that the active site of trimeric dUTPase is contributed by all three subunits. According to results from local structural comparisons, the active-site configuration of wDUT is similar to that of known dUTPases. However, we also found that residues in the second-shell region of the active site are reconfigured in wDUT as an adaption to its unique C terminal orientation. We also show that deletion of the pre-V insert significantly reduces wDUT's enzymatic activity and thermal stability. We hypothesize that this rare structural arrangement confers additional functionality to wDUT. In conclusion, our study expands the structural diversity in the conserved dUTPase family and illustrates how sequence insertion and amino acid substitution drive protein evolution cooperatively. PMID- 29187597 TI - Emerging roles of transcriptional enhancers in chromatin looping and promoter proximal pausing of RNA polymerase II. AB - Initiation and regulation of transcription by RNA polymerase II (RNAPII) in eukaryotes rely on the transcriptional regulatory elements. Promoters and enhancers share similar architectures and functions, and the prevailing view is that they can initiate bidirectional transcription. We summarize functional roles of enhancer transcription and possible mechanisms in enhancer-promoter communication. We discuss the potential roles of enhancer RNAs (eRNAs) in early elongation and highlight that transcriptional enhancers might modulate the release of paused RNAPII via 3D chromatin looping. Emerging evidence suggests that transcriptional enhancers regulate the promoter-proximal pausing of RNAPII, a key rate-limiting step required for productive elongation. PMID- 29187598 TI - Epitope-focused immunogens against the CD4-binding site of HIV-1 envelope protein induce neutralizing antibodies against auto- and heterologous viruses. AB - Recent discoveries of broadly neutralizing antibodies (bnAbs) in HIV-1-infected individuals have led to the identification of several major "vulnerable sites" on the HIV-1 envelope (Env) glycoprotein. These sites have provided precise targets for HIV-1 vaccine development, but identifying and utilizing many of these targets remain technically challenging. Using a yeast surface display-based approach, we sought to identify epitope-focused antigenic domains (EADs) containing one of the "vulnerable sites," the CD4-binding site (CD4bs), through screening and selection of a combinatorial antigen library of the HIV-1 envelope glycoprotein with the CD4bs bnAb VRC01. We isolated multiple EADs and found that their trimeric forms have biochemical and structural features that preferentially bind and activate B cells that express VRC01 in vitro More importantly, these EADs could induce detectable levels of neutralizing antibodies against genetically related autologous and heterologous subtype B viruses in guinea pigs. Our results demonstrate that an epitope-focused approach involving a screen of a combinatorial antigen library is feasible. The EADs identified here represent a promising collection of possible targets in the rational design of HIV-1 vaccines and lay the foundation for harnessing the specific antigenicity of CD4bs for protective immunogenicity in vivo. PMID- 29187599 TI - Oligomannosidic glycans at Asn-110 are essential for secretion of human diamine oxidase. AB - N-Glycosylation plays a fundamental role in many biological processes. Human diamine oxidase (hDAO), required for histamine catabolism, has multiple N glycosylation sites, but their roles, for example in DAO secretion, are unclear. We recently reported that the N-glycosylation sites Asn-168, Asn-538, and Asn-745 in recombinant hDAO (rhDAO) carry complex-type glycans, whereas Asn-110 carries only mammalian-atypical oligomannosidic glycans. Here, we show that Asn-110 in native hDAO from amniotic fluid and Caco-2 cells, DAO from porcine kidneys, and rhDAO produced in two different HEK293 cell lines is also consistently occupied by oligomannosidic glycans. Glycans at Asn-168 were predominantly sialylated with bi- to tetra-antennary branches, and Asn-538 and Asn-745 had similar complex-type glycans with some tissue- and cell line-specific variations. The related copper containing amine oxidase human vascular adhesion protein-1 also exclusively displayed high-mannose glycosylation at Asn-137. X-ray structures revealed that the residues adjacent to Asn-110 and Asn-137 form a highly conserved hydrophobic cleft interacting with the core trisaccharide. Asn-110 replacement with Gln completely abrogated rhDAO secretion and caused retention in the endoplasmic reticulum. Mutations of Asn-168, Asn-538, and Asn-745 reduced rhDAO secretion by 13, 71, and 32%, respectively. Asn-538/745 double and Asn-168/538/745 triple substitutions reduced rhDAO secretion by 85 and 94%. Because of their locations in the DAO structure, Asn-538 and Asn-745 glycosylations might be important for efficient DAO dimer formation. These functional results are reflected in the high evolutionary conservation of all four glycosylation sites. Human DAO is abundant only in the gastrointestinal tract, kidney, and placenta, and glycosylation seems essential for reaching high enzyme expression levels in these tissues.

AB - Neisseria meningitidis serogroups A and X are among the leading causes of bacterial meningitis in the African meningitis belt. Glycoconjugate vaccines, consisting of an antigenic carrier protein coupled to the capsular polysaccharide of the bacterial pathogen, are the most effective strategy for prevention of meningococcal disease. However, the distribution of effective glycoconjugate vaccines in this region is limited by the high cost of cultivating pathogens and purification of their capsular polysaccharides. Moreover, chemical approaches to synthesize oligosaccharide antigens have proven challenging. In the current study, we present a chemoenzymatic approach for generating tailored oligosaccharide fractions ready for activation and coupling to the carrier protein. In a first step, the elongation modes of recombinant capsular polymerases from Neisseria meningitidis serogroups A (CsaB) and X (CsxA) were characterized. We observed that CsaB is a distributive enzyme, and CsxA is a processive enzyme. Sequence comparison of these two stealth family proteins revealed a C-terminal extension in CsxA, which conferred processivity because of the existence of a second product-binding site. Deletion of the C-terminal domain converted CsxA into a distributive enzyme, allowing facile control of product length by adjusting the ratio of donor to acceptor sugars. Solid-phase fixation of the engineered capsular polymerases enabled rapid production of capsular polysaccharides with high yield and purity. In summary, the tools developed here provide critical steps toward reducing the cost of conjugate vaccine production, which will increase access in regions with the greatest need. Our work also facilitates efforts to study the relationship between oligosaccharide size and antigenicity. PMID- 29187600 TI - De novo expression of human polypeptide N-acetylgalactosaminyltransferase 6 (GalNAc-T6) in colon adenocarcinoma inhibits the differentiation of colonic epithelium. AB - Aberrant expression of O-glycans is a hallmark of epithelial cancers. Mucin-type O-glycosylation is initiated by a large family of UDP-GalNAc:polypeptide N acetylgalactosaminyltransferases (GalNAc-Ts) that target different proteins and are differentially expressed in cells and organs. Here, we investigated the expression patterns of all of the GalNAc-Ts in colon cancer by analyzing transcriptomic data. We found that GalNAc-T6 was highly up-regulated in colon adenocarcinomas but absent in normal-appearing adjacent colon tissue. These results were verified by immunohistochemistry, suggesting that GalNAc-T6 plays a role in colon carcinogenesis. To investigate the function of GalNAc-T6 in colon cancer, we used precise gene targeting to produce isogenic colon cancer cell lines with a knockout/rescue system for GALNT6 GalNAc-T6 expression was associated with a cancer-like, dysplastic growth pattern, whereas GALNT6 knockout cells showed a more normal differentiation pattern, reduced proliferation, normalized cell-cell adhesion, and formation of crypts in tissue cultures. O Glycoproteomic analysis of the engineered cell lines identified a small set of GalNAc-T6-specific targets, suggesting that this isoform has unique cellular functions. In support of this notion, the genetically and functionally closely related GalNAc-T3 homolog did not show compensatory functionality for effects observed for GalNAc-T6. Taken together, these data strongly suggest that aberrant GalNAc-T6 expression and site-specific glycosylation is involved in oncogenic transformation. PMID- 29187602 TI - TMEM16A and TMEM16B channel proteins generate Ca2+-activated Cl- current and regulate melatonin secretion in rat pineal glands. AB - Pinealocytes regulate circadian rhythm by synthesizing and secreting melatonin. These cells generate action potentials; however, the contribution of specific ion channels to melatonin secretion from pinealocytes remains unclear. In this study, the involvement and molecular identity of Ca2+-activated Cl- (ClCa) channels in the regulation of melatonin secretion were examined in rat pineal glands. Treatment with the ClCa channel blockers, niflumic acid or T16Ainh-A01, significantly reduced melatonin secretion in pineal glands. After pineal K+ currents were totally blocked under whole-cell patch clamp conditions, depolarization and subsequent repolarization induced a slowly activating outward current and a substantial inward tail current, respectively. Both of these current changes were dependent on intracellular Ca2+ concentration and inhibited by niflumic acid and T16Ainh-A01. Quantitative real-time PCR, Western blotting, and immunocytochemical analyses revealed that TMEM16A and TMEM16B were highly expressed in pineal glands. siRNA knockdown of TMEM16A and/or TMEM16B showed that both channels contribute to ClCa currents in pinealocytes. Conversely, co expression of TMEM16A and TMEM16B channels or the expression of this tandem channel in HEK293 cells mimicked the electrophysiological characteristics of ClCa currents in pinealocytes. Moreover, bimolecular fluorescence complementation, FRET, and co-immunoprecipitation experiments suggested that TMEM16A and TMEM16B can form heteromeric channels, as well as homomeric channels. In conclusion, pineal ClCa channels are composed of TMEM16A and TMEM16B subunits, and these fluxes regulate melatonin secretion in pineal glands. PMID- 29187603 TI - Defining the distinct, intrinsic properties of the novel type I interferon, IFNepsilon. AB - The type I interferons (IFNs) are a family of cytokines with diverse biological activities, including antiviral, antiproliferative, and immunoregulatory functions. The discovery of the hormonally regulated, constitutively expressed IFNepsilon has suggested a function for IFNs in reproductive tract homeostasis and protection from infections, but its intrinsic activities are untested. We report here the expression, purification, and functional characterization of murine IFNepsilon (mIFNepsilon). Recombinant mIFNepsilon (rmIFNepsilon) exhibited an alpha-helical fold characteristic of type I IFNs and bound to IFNalpha/beta receptor 1 (IFNAR1) and IFNAR2, but, unusually, it had a preference for IFNAR1. Nevertheless, rmIFNepsilon induced typical type I IFN signaling activity, including STAT1 phosphorylation and activation of canonical type I IFN signaling reporters, demonstrating that it uses the JAK-STAT signaling pathway. We also found that rmIFNepsilon induces the activation of T, B, and NK cells and exhibits antiviral, antiproliferative, and antibacterial activities typical of type I IFNs, albeit with 100-1000-fold reduced potency compared with rmIFNalpha1 and rmIFNbeta. Surprisingly, although the type I IFNs generally do not display cross species activities, rmIFNepsilon exhibited high antiviral activity on human cells, suppressing HIV replication and inducing the expression of known HIV restriction factors in human lymphocytes. Our findings define the intrinsic properties of murine IFNepsilon, indicating that it distinctly interacts with IFNAR and elicits pathogen-suppressing activity with a potency enabling host defense but with limited toxicity, appropriate for a protein expressed constitutively in a sensitive mucosal site, such as the reproductive tract. PMID- 29187604 TI - An invasive herbivore structures plant competitive dynamics. AB - Species interactions are central to our understanding of ecological communities, but may change rapidly with the introduction of invasive species. Invasive species can alter species interactions and community dynamics directly by having larger detrimental effects on some species than others, or indirectly by changing the ways in which native species compete among themselves. We tested the direct and indirect effects of an invasive aphid herbivore on a native aphid species and two host milkweed species. The invasive aphid caused a 10-fold decrease in native aphid populations, and a 30% increase in plant mortality (direct effects). The invasive aphid also increased the strength of interspecific competition between the two native plant hosts (indirect effects). By investigating the role that indirect effects play in shaping species interactions in native communities, our study highlights an understudied component of species invasions. PMID- 29187605 TI - Predictability of bee community composition after floral removals differs by floral trait group. AB - Plant-bee visitor communities are complex networks. While studies show that deleting nodes alters network topology, predicting these changes in the field remains difficult. Here, a simple trait-based approach is tested for predicting bee community composition following disturbance. I selected six fields with mixed cover of flower species with shallow (open) and deep (tube) nectar access, and removed all flowers or flower heads of species of each trait in different plots paired with controls, then observed bee foraging and composition. I compared the bee community in each manipulated plot with bees on the same flower species in control plots. The bee morphospecies composition in manipulations with only tube flowers remaining was the same as that in the control plots, while the bee morphospecies on only open flowers were dissimilar from those in control plots. However, the proportion of short- and long-tongued bees on focal flowers did not differ between control and manipulated plots for either manipulation. So, bees within some functional groups are more strongly linked to their floral trait partners than others. And, it may be more fruitful to describe expected bee community compositions in terms of relative proportions of relevant ecological traits than species, particularly in species-diverse communities. PMID- 29187606 TI - Studying placebo effects in model organisms will help us understand them in humans. AB - The placebo effect is widely recognized but important questions remain, for example whether the capacity to respond to a placebo is an evolved, and potentially ubiquitous trait, or an unpredictable side effect of another evolved process. Understanding this will determine the degree to which the physiology underlying placebo effects might be manipulated or harnessed to optimize medical treatments. We argue that placebo effects are cases of phenotypic plasticity where once predictable cues are now unpredictable. Importantly, this explains why placebo-like effects are observed in less complex organisms such as worms and flies. Further, this indicates that such species present significant opportunities to test hypotheses that would be ethically or pragmatically impossible in humans. This paradigm also suggests that data informative of human placebo effects pre-exist in studies of model organisms. PMID- 29187607 TI - Interactions between cleaner-birds and ungulates are personality dependent. AB - While a growing body of literature explores the ecological implications of consistent individual variation in the behaviour of wildlife, few studies have looked at the reciprocal influences of personality within interspecific interactions, despite the potentially significant impacts on biodiversity. Here I used two species involved in cleaner-bird behaviour-black-billed magpies (Pica pica) and Rocky mountain elk (Cervus canadensis)-to show that the exhibition of mutualistic behaviour can depend on the personality of the individual involved. I recorded suites of correlated behaviours in both elk and magpies to derive personality gradients from 'shy' to 'bold', which I compared with observations of interspecific interactions. I measured each half of this mutualistic relationship separately. I found that bold elk were more likely to aggressively reject magpie landings, while shy elk allowed magpies to land and groom them. Contrastingly, I found it was bold magpies that were willing to risk landings, while shy magpies rarely attempted landings. These results show that the exhibition of interspecific behaviour is predicated on the personality of the individuals, and thus likely contributes to the selection and maintenance of personality variation within populations. PMID- 29187608 TI - Structural biomechanics determine spectral purity of bush-cricket calls. AB - Bush-crickets (Orthoptera: Tettigoniidae) generate sound using tegminal stridulation. Signalling effectiveness is affected by the widely varying acoustic parameters of temporal pattern, frequency and spectral purity (tonality). During stridulation, frequency multiplication occurs as a scraper on one wing scrapes across a file of sclerotized teeth on the other. The frequency with which these tooth-scraper interactions occur, along with radiating wing cell resonant properties, dictates both frequency and tonality in the call. Bush-cricket species produce calls ranging from resonant, tonal calls through to non-resonant, broadband signals. The differences are believed to result from differences in file tooth arrangement and wing radiators, but a systematic test of the structural causes of broadband or tonal calls is lacking. Using phylogenetically controlled structural equation models, we show that parameters of file tooth density and file length are the best-fitting predictors of tonality across 40 bush-cricket species. Features of file morphology constrain the production of spectrally pure signals, but systematic distribution of teeth alone does not explain pure-tone sound production in this family. PMID- 29187609 TI - Associations between imprinted gene expression in the placenta, human fetal growth and preeclampsia. AB - Genomic imprinting is essential for normal placental and fetal growth. One theory to explain the evolution of imprinting is the kinship theory (KT), which predicts that genes that are paternally expressed will promote fetal growth, whereas maternally expressed genes will suppress growth. We investigated the expression of imprinted genes using microarray measurements of expression in term placentae. Correlations between birthweight and the expression levels of imprinted genes were more significant than for non-imprinted genes, but did not tend to be positive for paternally expressed genes and negative for maternally expressed genes. Imprinted genes were more dysregulated in preeclampsia (a disorder associated with placental insufficiency) than randomly selected genes, and we observed an excess of patterns of dysregulation in preeclampsia that would be expected to reduce nutrient allocation to the fetus, given the predictions of the KT. However, we found no evidence of coordinated regulation among these imprinted genes. A few imprinted genes have previously been shown to be associated with fetal growth and preeclampsia, and our results indicate that this is true for a broader set of imprinted genes.

PMID- 29187615 TI - Learning to starve: impacts of food limitation beyond the stress period. AB - Starvation is common among wild animal populations, and many individuals experience repeated bouts of starvation over the course of their lives. Although much information has been gained through laboratory studies of acute starvation, little is known about how starvation affects an animal once food is again available (i.e. during the refeeding and recovery phases). Many animals exhibit a curious phenomenon - some seem to 'get better' at starving following exposure to one or more starvation events - by this we mean that they exhibit potentially adaptive responses, including reduced rates of mass loss, reduced metabolic rates, and lower costs of digestion. During subsequent refeedings they may also exhibit improved digestive efficiency and more rapid mass gain. Importantly, these responses can last until the next starvation bout or even be inherited and expressed in the subsequent generation. Currently, however, little is known about the molecular regulation and physiological mechanisms underlying these changes. Here, we identify areas of research that can fill in the most pressing knowledge gaps. In particular, we highlight how recently refined techniques (e.g. stable isotope tracers, quantitative magnetic resonance and thermal measurement) as well as next-generation sequencing approaches (e.g. RNA-seq, proteomics and holobiome sequencing) can address specific starvation-focused questions. We also describe outstanding unknowns ripe for future research regarding the timing and severity of starvation, and concerning the persistence of these responses and their interactions with other ecological stressors. PMID- 29187616 TI - The evolution of honey bee dance communication: a mechanistic perspective. AB - Honey bee dance has been intensively studied as a communication system, and yet we still know very little about the neurobiological mechanisms supporting how dances are produced and interpreted. Here, we discuss how new information on the functions of the central complex (CX) of the insect brain might shed some light on possible neural mechanisms of dance behaviour. We summarise the features of dance communication across the species of the genus Apis We then propose that neural mechanisms of orientation and spatial processing found to be supported by the CX may function in dance communication also, and that this mechanistic link could explain some specific features of the dance form. This is purely a hypothesis, but in proposing this hypothesis, and how it might be investigated, we hope to stimulate new mechanistic analyses of dance communication. PMID- 29187617 TI - Considerations on the role of olfactory input in avian navigation. AB - A large amount of data documents an important role of olfactory input in pigeon navigation, but the nature of this role is not entirely clear. The olfactory navigation hypothesis assumes that odors are carrying essential navigational information, yet some recent experiments support an activating role of odors. This led to an ongoing controversy. An important, often-neglected aspect of the findings on olfaction is that olfactory deprivation affects avian navigation only at unfamiliar sites. The orientation of anosmic birds at familiar sites remains an enigma; earlier assumptions that they would rely on familiar landmarks have been disproven by the home-oriented behavior of anosmic pigeons additionally deprived of object vision, which clearly indicated the use by the birds of non visual, non-olfactory cues. However, if odors activate the establishing and enlarging of the navigational 'map' and promote the integration of local values of navigational factors into this map, it seems possible that such a process needs to occur only once at a given site, when the birds are visiting this site for the first time. If that were the case, the birds could interpret the local factors correctly at any later visit and orient by them. This hypothesis could explain the oriented behavior of birds at familiar sites, and it could also help to reconcile some of the seemingly controversial findings reported in the literature, where the effect of olfactory deprivation was reported to differ considerably between the various pigeon lofts, possibly because of different training procedures. PMID- 29187618 TI - Control surfaces of aquatic vertebrates: active and passive design and function. AB - Aquatic vertebrates display a variety of control surfaces that are used for propulsion, stabilization, trim and maneuvering. Control surfaces include paired and median fins in fishes, and flippers and flukes in secondarily aquatic tetrapods. These structures initially evolved from embryonic fin folds in fishes and have been modified into complex control surfaces in derived aquatic tetrapods. Control surfaces function both actively and passively to produce torque about the center of mass by the generation of either lift or drag, or both, and thus produce vector forces to effect rectilinear locomotion, trim control and maneuvers. In addition to fins and flippers, there are other structures that act as control surfaces and enhance functionality. The entire body can act as a control surface and generate lift for stability in destabilizing flow regimes. Furthermore, control surfaces can undergo active shape change to enhance their performance, and a number of features act as secondary control structures: leading edge tubercles, wing-like canards, multiple fins in series, finlets, keels and trailing edge structures. These modifications to control surface design can alter flow to increase lift, reduce drag and enhance thrust in the case of propulsive fin-based systems in fishes and marine mammals, and are particularly interesting subjects for future research and application to engineered systems. Here, we review how modifications to control surfaces can alter flow and increase hydrodynamic performance. PMID- 29187619 TI - Photoreceptor signalling is sufficient to explain the detectability threshold of insect aerial pursuers. AB - An essential biological task for many flying insects is the detection of small, moving targets, such as when pursuing prey or conspecifics. Neural pathways underlying such 'target-detecting' behaviours have been investigated for their sensitivity and tuning properties (size, velocity). However, which stage of neuronal processing limits target detection is not yet known. Here, we investigated several skilled, aerial pursuers (males of four insect species), measuring the target-detection limit (signal-to-noise ratio) of light-adapted photoreceptors. We recorded intracellular responses to moving targets of varying size, extended well below the nominal resolution of single ommatidia. We found that the signal detection limit (2* photoreceptor noise) matches physiological or behavioural target-detection thresholds observed in each species. Thus, across a diverse range of flying insects, individual photoreceptor responses to changes in light intensity establish the sensitivity of the feature detection pathway, indicating later stages of processing are dedicated to feature tuning, tracking and selection. PMID- 29187620 TI - Ocellar structure is driven by the mode of locomotion and activity time in Myrmecia ants. AB - Insects have exquisitely adapted their compound eyes to suit the ambient light intensity in the different temporal niches they occupy. In addition to the compound eye, most flying insects have simple eyes known as ocelli, which assist in flight stabilisation, horizon detection and orientation. Among ants, typically the flying alates have ocelli while the pedestrian workers lack this structure. The Australian ant genus Myrmecia is one of the few ant genera in which both workers and alates have three ocellar lenses. Here, we studied the variation in the ocellar structure in four sympatric species of Myrmecia that are active at different times of the day. In addition, we took advantage of the walking and flying modes of locomotion in workers and males, respectively, to ask whether the type of movement influences the ocellar structure. We found that ants active in dim light had larger ocellar lenses and wider rhabdoms compared with those in bright-light conditions. In the ocellar rhabdoms of workers active in dim-light habitats, typically each retinula cell contributed microvilli in more than one direction, probably destroying polarisation sensitivity. The organisation of the ocellar retina in the day-active workers and the males suggests that in these animals some cells are sensitive to the pattern of polarised skylight. We found that the night-flying males had a tapetum that reflects light back to the rhabdom, increasing their optical sensitivity. We discuss the possible functions of ocelli to suit the different modes of locomotion and the discrete temporal niches that animals occupy. PMID- 29187621 TI - Flight metabolic rate of Locusta migratoria in relation to oxygen partial pressure in atmospheres of varying diffusivity and density. AB - Flying insects have the highest mass-specific metabolic rate of all animals. Oxygen is supplied to the flight muscles by a combination of diffusion and convection along the internal air-filled tubes of the tracheal system. This study measured maximum flight metabolic rate (FMR) during tethered flight in the migratory locust Locusta migratoria under varying oxygen partial pressure (PO2 ) in background gas mixtures of nitrogen (N2), sulfur hexafluoride (SF6) and helium (He), to vary O2 diffusivity and gas mixture density independently. With N2 as the sole background gas (normodiffusive-normodense), mass-independent FMR averaged 132+/-19 mW g-0.75 at normoxia (PO2 =21 kPa), and was not limited by tracheal system conductance, because FMR did not increase in hyperoxia. However, FMR declined immediately with hypoxia, oxy-conforming nearly completely. Thus, the locust respiratory system is matched to maximum functional requirements, with little reserve capacity. With SF6 as the sole background gas (hypodiffusive hyperdense), the shape of the relationship between FMR and PO2 was similar to that in N2, except that FMR was generally lower (e.g. 24% lower at normoxia). This appeared to be due to increased density of the gas mixture rather than decreased O2 diffusivity, because hyperoxia did not reverse it. Normoxic FMR was not significantly different in He-SF6 (hyperdiffusive-normodense) compared with the N2 background gas, and likewise there was no significant difference between FMR in SF6-He (normodiffusive-hyperdense) compared with the SF6 background gas. The results indicate that convection, not diffusion, is the main mechanism of O2 delivery to the flight muscle of the locust when demand is high. PMID- 29187622 TI - Swim bladder morphology changes with female reproductive state in the mouth brooding African cichlid Astatotilapia burtoni. AB - Mouth brooding is an extreme form of parental care in which the brooding parent carries the developing young in their buccal cavity for the duration of development. Brooding fish need to compensate for the brood weight on the anterior portion of their body. For fishes with a compartmentalized swim bladder, gas distribution between the chambers may aid in regulating buoyancy during brooding. To test this hypothesis, we took radiographs of Astatotilapia burtoni to compare the swim bladder morphology of gravid, mouth-brooding and recovering females. Following spawning, females carry developing fish in their buccal cavity for ~2 weeks, resulting in a larger and rounder anterior swim bladder compartment. Comparatively, the swim bladder of gravid females is long and cylindrical. Using small beads to mimic brood weight and its effects on female buoyancy, swim bladder changes were induced that resembled those observed during brooding. Immediately after releasing their fry, brooding females swim at a positive angle of attack but correct their swimming posture to normal within 5 min, suggesting a rapid change in swim bladder gas distribution. These data provide new insights into how swim bladder morphology and swimming behavior change during mouth brooding, and suggest a compartmentalized swim bladder may be a morphological adaptation for mouth brooding. PMID- 29187623 TI - Skill not athleticism predicts individual variation in match performance of soccer players. AB - Just as evolutionary biologists endeavour to link phenotypes to fitness, sport scientists try to identify traits that determine athlete success. Both disciplines would benefit from collaboration, and to illustrate this, we used an analytical approach common to evolutionary biology to isolate the phenotypes that promote success in soccer, a complex activity of humans played in nearly every modern society. Using path analysis, we quantified the relationships among morphology, balance, skill, athleticism and performance of soccer players. We focused on performance in two complex motor activities: a simple game of soccer tennis (1 on 1), and a standard soccer match (11 on 11). In both contests, players with greater skill and balance were more likely to perform better. However, maximal athletic ability was not associated with success in a game. A social network analysis revealed that skill also predicted movement. The relationships between phenotypes and success during individual and team sports have potential implications for how selection acts on these phenotypes, in humans and other species, and thus should ultimately interest evolutionary biologists. Hence, we propose a field of evolutionary sports science that lies at the nexus of evolutionary biology and sports science. This would allow biologists to take advantage of the staggering quantity of data on performance in sporting events to answer evolutionary questions that are more difficult to answer for other species. In return, sports scientists could benefit from the theoretical framework developed to study natural selection in non-human species. PMID- 29187624 TI - Delayed behavioural shifts undermine the sustainability of social-ecological systems. AB - Natural habitat destruction and fragmentation generate a time-delayed loss of species and associated ecosystem services. As social-ecological systems (SESs) depend on a range of ecosystem services, lagged ecological dynamics may affect their long-term sustainability. Here, we investigate the role of consumption changes for sustainability, under a time-delayed ecological feedback on agricultural production. We use a stylized model that couples the dynamics of biodiversity, technology, human demography and compliance with a social norm prescribing sustainable consumption. Compliance with the sustainable norm reduces both the consumption footprint and the vulnerability of SESs to transient overshoot-and-collapse population crises. We show that the timing and interaction between social, demographic and ecological feedbacks govern the transient and long-term dynamics of the system. A sufficient level of social pressure (e.g. disapproval) applied on the unsustainable consumers leads to the stable coexistence of unsustainable and sustainable or mixed equilibria, where both defectors and conformers coexist. Under bistability conditions, increasing extinction debts reduces the resilience of the system, thus favouring abrupt regime shifts towards unsustainable pathways. Given recent evidence of large extinction debts, such results call for farsightedness and a better understanding of time delays when studying the sustainability of coupled SESs. PMID- 29187625 TI - Cooperative breeding influences the number and type of vocalizations in avian lineages. AB - Although communicative complexity is often predicted to correlate with social complexity in animal societies, few studies have employed large-scale comparative analyses to test whether socially complex species have more complex systems of communication. I tested this social complexity hypothesis in birds (Class: Aves) using the large amount of natural history information that describes both vocal repertoire and social system in these species. To do so, I marshalled data from primary and secondary records of avian vocal repertoires (n = 253), and for each of the species in the dataset I recorded the reported repertoire size and associated species information. Using phylogenetic comparative methods, I found that cooperative breeding was a strong and repeatable predictor of vocal repertoire size, while other social variables, e.g. group size and group stability, had little or no influence on repertoire size. Importantly, repertoire sizes expanded concurrently with the evolution of cooperative breeding, suggesting a direct link between these two traits. Cooperatively breeding species devoted significantly more of their repertoire to contact calls and alarm calls. Overall, these results therefore lend support to the hypothesis that social complexity via behavioural coordination leads to increases in vocal complexity. PMID- 29187626 TI - A load-based mechanism for inter-leg coordination in insects. AB - Animals rely on an adaptive coordination of legs during walking. However, which specific mechanisms underlie coordination during natural locomotion remains largely unknown. One hypothesis is that legs can be coordinated mechanically based on a transfer of body load from one leg to another. To test this hypothesis, we simultaneously recorded leg kinematics, ground reaction forces and muscle activity in freely walking stick insects (Carausius morosus). Based on torque calculations, we show that load sensors (campaniform sensilla) at the proximal leg joints are well suited to encode the unloading of the leg in individual steps. The unloading coincides with a switch from stance to swing muscle activity, consistent with a load reflex promoting the stance-to-swing transition. Moreover, a mechanical simulation reveals that the unloading can be ascribed to the loading of a specific neighbouring leg, making it exploitable for inter-leg coordination. We propose that mechanically mediated load-based coordination is used across insects analogously to mammals. PMID- 29187627 TI - Selective harvest focused on sexual signal traits can lead to extinction under directional environmental change. AB - Humans commonly harvest animals based on their expression of secondary sexual traits such as horns or antlers. This selective harvest is thought to have little effect on harvested populations because offtake rates are low and usually only the males are targeted. These arguments do not, however, take the relationship between secondary sexual trait expression and animal condition into account: there is increasing evidence that in many cases the degree of expression of such traits is correlated with an animal's overall well-being, which is partly determined by their genetic match to the environment. Using an individual-based model, we find that when there is directional environmental change, selective harvest of males with the largest secondary sexual traits can lead to extinction in otherwise resilient populations. When harvest is not selective, the males best suited to a new environment gain the majority of matings and beneficial alleles spread rapidly. When these best-adapted males are removed, however, their beneficial alleles are lost, leading to extinction. Given the current changes happening globally, these results suggest that trophy hunting and other cases of selective harvest (such as certain types of insect collection) should be managed with extreme care whenever populations are faced with changing conditions. PMID- 29187628 TI - The genetic basis and enigmatic origin of melanic polymorphism in pomarine skuas (Stercorarius pomarinus). AB - A key outstanding issue in adaptive evolution is the relationship between the genetics of intraspecific polymorphism and interspecific evolution. Here, we show that the pale/dark ventral plumage polymorphism that occurs in both the pomarine skua (Stercorarius pomarinus) and Arctic skua (S. parasiticus) is the result of convergent evolution at the same locus (MC1R), involving some of the same amino acid sites. The dark melanic MC1R allele in the pomarine skua is strongly divergent from the pale MC1R alleles. Whereas the dark allele is closely related to MC1R alleles in three species of great skua (S. skua, S. maccormicki, S. lonnbergi), the pale pomarine skua MC1R alleles present a star-like pattern in an intermediate position on the haplotype network, closer to alleles of the long tailed skua (S. longicaudus). Variation at other nuclear loci confirms a close relationship between the pomarine skua and the great skuas. The plumage polymorphism in pomarine skuas might have arisen in the common ancestor of pomarine and great skuas, only being retained in pomarine skuas. Alternatively, the pale and melanic MC1R alleles may have evolved independently in different lineages and been brought together in pomarine skuas by hybridization. In this case, introgression of a pale MC1R allele into the pomarine skua from another skua lineage is most likely. Our current data do not permit us to distinguish between these hypotheses, and assaying genome-wide variation holds much promise in this regard. Nevertheless, we have uncovered an intriguing example of a functionally important allele within one species that is shared across species. PMID- 29187629 TI - Testing differential use of payoff-biased social learning strategies in children and chimpanzees. AB - Various non-human animal species have been shown to exhibit behavioural traditions. Importantly, this research has been guided by what we know of human culture, and the question of whether animal cultures may be homologous or analogous to our own culture. In this paper, we assess whether models of human cultural transmission are relevant to understanding biological fundamentals by investigating whether accounts of human payoff-biased social learning are relevant to chimpanzees (Pan troglodytes). We submitted 4- and 5-year-old children (N = 90) and captive chimpanzees (N = 69) to a token-reward exchange task. The results revealed different forms of payoff-biased learning across species and contexts. Specifically, following personal and social exposure to different tokens, children's exchange behaviour was consistent with proportional imitation, where choice is affected by both prior personally acquired and socially demonstrated token-reward information. However, when the socially derived information regarding token value was novel, children's behaviour was consistent with proportional observation; paying attention to socially derived information and ignoring their prior personal experience. By contrast, chimpanzees' token choice was governed by their own prior experience only, with no effect of social demonstration on token choice, conforming to proportional reservation. We also find evidence for individual- and group-level differences in behaviour in both species. Despite the difference in payoff strategies used, both chimpanzees and children adopted beneficial traits when available. However, the strategies of the children are expected to be the most beneficial in promoting flexible behaviour by enabling existing behaviours to be updated or replaced with new and often superior ones.

AB - Although anecdotally associated with local bears (Ursus arctos and U. thibetanus), the exact identity of 'hominid'-like creatures important to folklore and mythology in the Tibetan Plateau-Himalaya region is still surrounded by mystery. Recently, two purported yeti samples from the Himalayas showed genetic affinity with an ancient polar bear, suggesting they may be from previously unrecognized, possibly hybrid, bear species, but this preliminary finding has been under question. We conducted a comprehensive genetic survey of field collected and museum specimens to explore their identity and ultimately infer the evolutionary history of bears in the region. Phylogenetic analyses of mitochondrial DNA sequences determined clade affinities of the purported yeti samples in this study, strongly supporting the biological basis of the yeti legend to be local, extant bears. Complete mitochondrial genomes were assembled for Himalayan brown bear (U. a. isabellinus) and black bear (U. t. laniger) for the first time. Our results demonstrate that the Himalayan brown bear is one of the first-branching clades within the brown bear lineage, while Tibetan brown bears diverged much later. The estimated times of divergence of the Tibetan Plateau and Himalayan bear lineages overlap with Middle to Late Pleistocene glaciation events, suggesting that extant bears in the region are likely descendants of populations that survived in local refugia during the Pleistocene glaciations.

AB - Understanding how species have replaced each other in the past is important to predicting future species turnover. While past species replacement is difficult to detect after the fact, the process may be inferred from present-day distribution patterns. Species with abutting ranges sometimes show a characteristic distribution pattern, where a section of one species range is enveloped by that of the other. Such an enclave could indicate past species replacement: when a species is partly supplanted by a competitor, but a population endures locally while the invading species moves around and past it, an enclave forms. If the two species hybridize and backcross, the receding species is predicted to leave genetic traces within the expanding one under a scenario of species replacement. By screening dozens of genes in hybridizing crested newts, we uncover genetic remnants of the ancestral species, now inhabiting an enclave, in the range of the surrounding invading species. This independent genetic evidence supports the past distribution dynamics we predicted from the enclave. We suggest that enclaves provide a valuable tool in understanding historical species replacement, which is important because a major conservation concern arising from anthropogenic climate change is increased species replacement in the future. PMID- 29187632 TI - Selection bias in studies of human reproduction-longevity trade-offs. AB - A shorter lifespan as a potential cost of high reproductive effort in humans has intrigued researchers for more than a century. However, the results have been inconclusive so far and despite strong theoretical expectations we do not currently have compelling evidence for the longevity costs of reproduction. Using Monte Carlo simulation, it is shown here that a common practice in human reproduction-longevity studies using historical data (the most relevant data sources for this question), the omission of women who died prior to menopausal age from the analysis, results in severe underestimation of the potential underlying trade-off between reproduction and lifespan. In other words, assuming that such a trade-off is expressed also during reproductive years, the strength of the trade-off between reproduction and lifespan is progressively weakened when women dying during reproductive ages are sequentially and non-randomly excluded from the analysis. In cases of small sample sizes (e.g. few hundreds of observations), this selection bias by reducing statistical power may even partly explain the null results commonly found in this field. Future studies in this field should thus apply statistical approaches that account for or avoid selection bias in order to recover reliable effect size estimates between reproduction and longevity. PMID- 29187633 TI - Adversity magnifies the importance of social information in decision-making. AB - Decision-making theories explain animal behaviour, including human behaviour, as a response to estimations about the environment. In the case of collective behaviour, they have given quantitative predictions of how animals follow the majority option. However, they have so far failed to explain that in some species and contexts social cohesion increases when conditions become more adverse (i.e. individuals choose the majority option with higher probability when the estimated quality of all available options decreases). We have found that this failure is due to modelling simplifications that aided analysis, like low levels of stochasticity or the assumption that only one choice is the correct one. We provide a more general but simple geometric framework to describe optimal or suboptimal decisions in collectives that gives insight into three different mechanisms behind this effect. The three mechanisms have in common that the private information acts as a gain factor to social information: a decrease in the privately estimated quality of all available options increases the impact of social information, even when social information itself remains unchanged. This increase in the importance of social information makes it more likely that agents will follow the majority option. We show that these results quantitatively explain collective behaviour in fish and experiments of social influence in humans. PMID- 29187634 TI - Evidence-based controls for epidemics using spatio-temporal stochastic models in a Bayesian framework. AB - The control of highly infectious diseases of agricultural and plantation crops and livestock represents a key challenge in epidemiological and ecological modelling, with implemented control strategies often being controversial. Mathematical models, including the spatio-temporal stochastic models considered here, are playing an increasing role in the design of control as agencies seek to strengthen the evidence on which selected strategies are based. Here, we investigate a general approach to informing the choice of control strategies using spatio-temporal models within the Bayesian framework. We illustrate the approach for the case of strategies based on pre-emptive removal of individual hosts. For an exemplar model, using simulated data and historic data on an epidemic of Asiatic citrus canker in Florida, we assess a range of measures for prioritizing individuals for removal that take account of observations of an emerging epidemic. These measures are based on the potential infection hazard a host poses to susceptible individuals (hazard), the likelihood of infection of a host (risk) and a measure that combines both the hazard and risk (threat). We find that the threat measure typically leads to the most effective control strategies particularly for clustered epidemics when resources are scarce. The extension of the methods to a range of other settings is discussed. A key feature of the approach is the use of functional-model representations of the epidemic model to couple epidemic trajectories under different control strategies. This induces strong positive correlations between the epidemic outcomes under the respective controls, serving to reduce both the variance of the difference in outcomes and, consequently, the need for extensive simulation. PMID- 29187635 TI - Structural similarities in the CPC clip motif explain peptide-binding promiscuity between glycosaminoglycans and lipopolysaccharides. AB - Lipopolysaccharides (LPSs) and glycosaminoglycans (GAGs) are polymeric structures containing negatively charged disaccharide units that bind to specialized proteins and peptides in the human body and control fundamental processes such as inflammation and coagulation. Surprisingly, some proteins can bind both LPSs and GAGs with high affinity, suggesting that a cross-communication between these two pathways can occur. Here, we explore whether GAGs and LPSs can share common binding sites in proteins and what are the structural determinants of this binding. We found that the LPS-binding peptide YI12WF, derived from protein FhuA, can bind both heparin and E. coli LPS with high affinity. Most interestingly, mutations decreasing heparin binding in the peptide also reduce LPS affinity. We show that such mutations involve the CPC clip motif in the peptide, a small three dimensional signature required for heparin binding. Overall, we conclude that negatively charged polysaccharide-containing polymers such as GAGs and LPSs can compete for similar binding sites in proteins, and that the CPC clip motif is essential to bind both ligands. Our results provide a structural framework to explain why these polymers can cross-interact with the same proteins and peptides and thus contribute to the regulation of apparently unrelated processes in the body. PMID- 29187636 TI - Making sense of snapshot data: ergodic principle for clonal cell populations. AB - Population growth is often ignored when quantifying gene expression levels across clonal cell populations. We develop a framework for obtaining the molecule number distributions in an exponentially growing cell population taking into account its age structure. In the presence of generation time variability, the average acquired across a population snapshot does not obey the average of a dividing cell over time, apparently contradicting ergodicity between single cells and the population. Instead, we show that the variation observed across snapshots with known cell age is captured by cell histories, a single-cell measure obtained from tracking an arbitrary cell of the population back to the ancestor from which it originated. The correspondence between cells of known age in a population with their histories represents an ergodic principle that provides a new interpretation of population snapshot data. We illustrate the principle using analytical solutions of stochastic gene expression models in cell populations with arbitrary generation time distributions. We further elucidate that the principle breaks down for biochemical reactions that are under selection, such as the expression of genes conveying antibiotic resistance, which gives rise to an experimental criterion with which to probe selection on gene expression fluctuations. PMID- 29187637 TI - Mathematical modelling of microbes: metabolism, gene expression and growth. AB - The growth of microorganisms involves the conversion of nutrients in the environment into biomass, mostly proteins and other macromolecules. This conversion is accomplished by networks of biochemical reactions cutting across cellular functions, such as metabolism, gene expression, transport and signalling. Mathematical modelling is a powerful tool for gaining an understanding of the functioning of this large and complex system and the role played by individual constituents and mechanisms. This requires models of microbial growth that provide an integrated view of the reaction networks and bridge the scale from individual reactions to the growth of a population. In this review, we derive a general framework for the kinetic modelling of microbial growth from basic hypotheses about the underlying reaction systems. Moreover, we show that several families of approximate models presented in the literature, notably flux balance models and coarse-grained whole-cell models, can be derived with the help of additional simplifying hypotheses. This perspective clearly brings out how apparently quite different modelling approaches are related on a deeper level, and suggests directions for further research. PMID- 29187638 TI - Numb prevents a complete epithelial-mesenchymal transition by modulating Notch signalling. AB - Epithelial-mesenchymal transition (EMT) plays key roles during embryonic development, wound healing and cancer metastasis. Cells in a partial EMT or hybrid epithelial/mesenchymal (E/M) phenotype exhibit collective cell migration, forming clusters of circulating tumour cells-the primary drivers of metastasis. Activation of cell-cell signalling pathways such as Notch fosters a partial or complete EMT, yet the mechanisms enabling cluster formation remain poorly understood. Using an integrated computational-experimental approach, we examine the role of Numb-an inhibitor of Notch intercellular signalling-in mediating EMT and clusters formation. We show via an mathematical model that Numb inhibits a full EMT by stabilizing a hybrid E/M phenotype. Consistent with this observation, knockdown of Numb in stable hybrid E/M cells H1975 results in a full EMT, thereby showing that Numb acts as a brake for a full EMT and thus behaves as a 'phenotypic stability factor' by modulating Notch-driven EMT. By generalizing the mathematical model to a multi-cell level, Numb is predicted to alter the balance of hybrid E/M versus mesenchymal cells in clusters, potentially resulting in a higher tumour-initiation ability. Finally, Numb correlates with a worse survival in multiple independent lung and ovarian cancer datasets, hence confirming its relationship with increased cancer aggressiveness. PMID- 29187639 TI - Identifying spatio-temporal dynamics of Ebola in Sierra Leone using virus genomes. AB - Containing the recent West African outbreak of Ebola virus (EBOV) required the deployment of substantial global resources. Despite recent progress in analysing and modelling EBOV epidemiological data, a complete characterization of the spatio-temporal spread of Ebola cases remains a challenge. In this work, we offer a novel perspective on the EBOV epidemic in Sierra Leone that uses individual virus genome sequences to inform population-level, spatial models. Calibrated to phylogenetic linkages of virus genomes, these spatial models provide unique insight into the disease mobility of EBOV in Sierra Leone without the need for human mobility data. Consistent with other investigations, our results show that the spread of EBOV during the beginning and middle portions of the epidemic strongly depended on the size of and distance between populations. Our phylodynamic analysis also revealed a change in model preference towards a spatial model with power-law characteristics in the latter portion of the epidemic, correlated with the timing of major intervention campaigns. More generally, we believe this framework, pairing molecular diagnostics with a dynamic model selection procedure, has the potential to be a powerful forecasting tool along with offering operationally relevant guidance for surveillance and sampling strategies during an epidemic. PMID- 29187640 TI - Generative models for network neuroscience: prospects and promise. AB - Network neuroscience is the emerging discipline concerned with investigating the complex patterns of interconnections found in neural systems, and identifying principles with which to understand them. Within this discipline, one particularly powerful approach is network generative modelling, in which wiring rules are algorithmically implemented to produce synthetic network architectures with the same properties as observed in empirical network data. Successful models can highlight the principles by which a network is organized and potentially uncover the mechanisms by which it grows and develops. Here, we review the prospects and promise of generative models for network neuroscience. We begin with a primer on network generative models, with a discussion of compressibility and predictability, and utility in intuiting mechanisms, followed by a short history on their use in network science, broadly. We then discuss generative models in practice and application, paying particular attention to the critical need for cross-validation. Next, we review generative models of biological neural networks, both at the cellular and large-scale level, and across a variety of species including Caenorhabditis elegans, Drosophila, mouse, rat, cat, macaque and human. We offer a careful treatment of a few relevant distinctions, including differences between generative models and null models, sufficiency and redundancy, inferring and claiming mechanism, and functional and structural connectivity. We close with a discussion of future directions, outlining exciting frontiers both in empirical data collection efforts as well as in method and theory development that, together, further the utility of the generative network modelling approach for network neuroscience. PMID- 29187641 TI - Vasopressin stimulates the proliferation and differentiation of red blood cell precursors and improves recovery from anemia. AB - Arginine vasopressin (AVP) made by hypothalamic neurons is released into the circulation to stimulate water resorption by the kidneys and restore water balance after blood loss. Patients who lack this antidiuretic hormone suffer from central diabetes insipidus. We observed that many of these patients were anemic and asked whether AVP might play a role in red blood cell (RBC) production. We found that all three AVP receptors are expressed in human and mouse hematopoietic stem and progenitor cells. The AVPR1B appears to play the most important role in regulating erythropoiesis in both human and mouse cells. AVP increases phosphorylation of signal transducer and activator of transcription 5, as erythropoietin (EPO) does. After sublethal irradiation, AVP-deficient Brattleboro rats showed delayed recovery of RBC numbers compared to control rats. In mouse models of anemia (induced by bleeding, irradiation, or increased destruction of circulating RBCs), AVP increased the number of circulating RBCs independently of EPO. In these models, AVP appears to jump-start peripheral blood cell replenishment until EPO can take over. We suggest that specific AVPR1B agonists might be used to induce fast RBC production after bleeding, drug toxicity, or chemotherapy. PMID- 29187642 TI - Irisin protects mitochondria function during pulmonary ischemia/reperfusion injury. AB - Limb remote ischemic preconditioning (RIPC) is an effective means of protection against ischemia/reperfusion (IR)-induced injury to multiple organs. Many studies are focused on identifying endocrine mechanisms that underlie the cross-talk between muscle and RIPC-mediated organ protection. We report that RIPC releases irisin, a myokine derived from the extracellular portion of fibronectin domain containing 5 protein (FNDC5) in skeletal muscle, to protect against injury to the lung. Human patients with neonatal respiratory distress syndrome show reduced concentrations of irisin in the serum and increased irisin concentrations in the bronchoalveolar lavage fluid, suggesting transfer of irisin from circulation to the lung under physiologic stress. In mice, application of brief periods of ischemia preconditioning stimulates release of irisin into circulation and transfer of irisin to the lung subjected to IR injury. Irisin, via lipid raft mediated endocytosis, enters alveolar cells and targets mitochondria. Interaction between irisin and mitochondrial uncoupling protein 2 (UCP2) allows for prevention of IR-induced oxidative stress and preservation of mitochondrial function. Animal model studies show that intravenous administration of exogenous irisin protects against IR-induced injury to the lung via improvement of mitochondrial function, whereas in UCP2-deficient mice or in the presence of a UCP2 inhibitor, the protective effect of irisin is compromised. These results demonstrate that irisin is a myokine that facilitates RIPC-mediated lung protection. Targeting the action of irisin in mitochondria presents a potential therapeutic intervention for pulmonary IR injury. PMID- 29187644 TI - Nanoparticle targeting to the endothelium during normothermic machine perfusion of human kidneys. AB - Ex vivo normothermic machine perfusion (NMP) is a new clinical strategy to assess and resuscitate organs likely to be declined for transplantation, thereby increasing the number of viable organs available. Short periods of NMP provide a window of opportunity to deliver therapeutics directly to the organ and, in particular, to the vascular endothelial cells (ECs) that constitute the first point of contact with the recipient's immune system. ECs are the primary targets of both ischemia-reperfusion injury and damage from preformed antidonor antibodies, and reduction of perioperative EC injury could have long-term benefits by reducing the intensity of the host's alloimmune response. Using NMP to administer therapeutics directly to the graft avoids many of the limitations associated with systemic drug delivery. We have previously shown that polymeric nanoparticles (NPs) can serve as depots for long-term drug release, but ensuring robust NP accumulation within a target cell type (graft ECs in this case) remains a fundamental challenge of nanomedicine. We show that surface conjugation of an anti-CD31 antibody enhances targeting of NPs to graft ECs of human kidneys undergoing NMP. Using a two-color quantitative microscopy approach, we demonstrate that targeting can enhance EC accumulation by about 5- to 10-fold or higher in discrete regions of the renal vasculature. In addition, our studies reveal that NPs can also nonspecifically accumulate within obstructed regions of the vasculature that are poorly perfused. These quantitative preclinical human studies demonstrate the therapeutic potential for targeted nanomedicines delivered during ex vivo NMP.

AB - Glycogen storage disease type II or Pompe disease is a severe neuromuscular disorder caused by mutations in the lysosomal enzyme, acid alpha-glucosidase (GAA), which result in pathological accumulation of glycogen throughout the body. Enzyme replacement therapy is available for Pompe disease; however, it has limited efficacy, has high immunogenicity, and fails to correct pathological glycogen accumulation in nervous tissue and skeletal muscle. Using bioinformatics analysis and protein engineering, we developed transgenes encoding GAA that could be expressed and secreted by hepatocytes. Then, we used adeno-associated virus (AAV) vectors optimized for hepatic expression to deliver the GAA transgenes to Gaa knockout (Gaa-/-) mice, a model of Pompe disease. Therapeutic gene transfer to the liver rescued glycogen accumulation in muscle and the central nervous system, and ameliorated cardiac hypertrophy as well as muscle and respiratory dysfunction in the Gaa-/- mice; mouse survival was also increased. Secretable GAA showed improved therapeutic efficacy and lower immunogenicity compared to nonengineered GAA. Scale-up to nonhuman primates, and modeling of GAA expression in primary human hepatocytes using hepatotropic AAV vectors, demonstrated the therapeutic potential of AAV vector-mediated liver expression of secretable GAA for treating pathological glycogen accumulation in multiple tissues in Pompe disease. PMID- 29187648 TI - AC signal characterization for optimization of a CMOS single-electron pump. AB - Pumping single electrons at a set rate is being widely pursued as an electrical current standard. Semiconductor charge pumps have been pursued in a variety of modes, including single gate ratchet, a variety of 2-gate ratchet pumps, and 2 gate turnstiles. Whether pumping with one or two AC signals, lower error rates can result from better knowledge of the properties of the AC signal at the device. In this work, we operated a CMOS single-electron pump with a 2-gate ratchet style measurement and used the results to characterize and optimize our two AC signals. Fitting this data at various frequencies revealed both a difference in signal path length and attenuation between our two AC lines. Using this data, we corrected for the difference in signal path length and attenuation by applying an offset in both the phase and the amplitude at the signal generator. Operating the device as a turnstile while using the optimized parameters determined from the 2-gate ratchet measurement led to much flatter, more robust charge pumping plateaus. This method was useful in tuning our device up for optimal charge pumping, and may prove useful to the semiconductor quantum dot community to determine signal attenuation and path differences at the device. PMID- 29187645 TI - Single-cut genome editing restores dystrophin expression in a new mouse model of muscular dystrophy. AB - Duchenne muscular dystrophy (DMD) is a severe, progressive muscle disease caused by mutations in the dystrophin gene. The majority of DMD mutations are deletions that prematurely terminate the dystrophin protein. Deletions of exon 50 of the dystrophin gene are among the most common single exon deletions causing DMD. Such mutations can be corrected by skipping exon 51, thereby restoring the dystrophin reading frame. Using clustered regularly interspaced short palindromic repeats/CRISPR-associated 9 (CRISPR/Cas9), we generated a DMD mouse model by deleting exon 50. These DeltaEx50 mice displayed severe muscle dysfunction, which was corrected by systemic delivery of adeno-associated virus encoding CRISPR/Cas9 genome editing components. We optimized the method for dystrophin reading frame correction using a single guide RNA that created reframing mutations and allowed skipping of exon 51. In conjunction with muscle-specific expression of Cas9, this approach restored up to 90% of dystrophin protein expression throughout skeletal muscles and the heart of DeltaEx50 mice. This method of permanently bypassing DMD mutations using a single cut in genomic DNA represents a step toward clinical correction of DMD mutations and potentially those of other neuromuscular disorders.

AB - OBJECTIVE: To explore the role of interleukin (IL)-6 in gastric cancer cells and the mechanisms.? Methods: Gastric cancer cells MGC-803 were treated with 50 ng/mL of recombinant IL-6 protein, and then cell viability and cell migration were detected by MTT assay and wound-healing assay, respectively. The mRNA and protein expressions of E-cadherin, N-cadherin, vimentin, Snail1 and miR-152 were analyzed by RT-qPCR and Western blot, respectively. Moreover, MGC-803 cells were simultaneously or separately treated with IL-6 and transfected with miR-152 mimics, and then the mRNA expression of PIK3R3 and the protein levels of PIK3R3, Akt and p-Akt were determined.? Results: IL-6 stimulation significantly promoted cell proliferation and migration, reduced the expression of E-cadherin and miR 152, and increased the expression of N-cadherin, vimentin, Snail1, PIK3R3 and p Akt (All P<0.05). The protein levels of PIK3R3 and p-Akt were significantly decreased after transfecting miR-152 mimics into MGC-803 cells (P<0.01). miR-152 overexpression down-regulated IL-6-induced the protein expression of PIK3R3 and p Akt (P<0.01). The levels of Akt in each group were not changed.? Conclusion: IL-6 up-regulates PIK3R3 expression and activates PI3K/Akt signaling pathway through down-regulating miR-152 expression, which consequently promotes gastric cancer cell proliferation, migration, and epithelial-mesenchymal transition. PMID- 29187650 TI - [Transhepatic arterial embolization with superparamagnetic iron oxide and lipiodol for the treatment of VX2 tumor in rabbits]. AB - OBJECTIVE: To evaluate the feasibility and therapeutic efficacy of transhepatic arterial embolization with superparamagnetic iron oxide (SPIO) and lipiodol (LIP) for the treatment of VX2 tumor in rabbits.? Methods: Twenty-four rabbits with hepatic VX2 tumors by surgical implantation were randomly divided into 4 groups and treated with transhepatic arterial embolization of 4 different agents as follows (n=6 each): doxorubicin (DOX) group, DOX-LIP group, SPIO-DOX group, and SPIO-DOX-LIP group. Liver function (AST and ALT) was measured at 0, 1, 3, 5 and 7 d after transhepatic arterial embolization. The serum DOX level was measured at 0, 5, 15, 30, 60, and 120 minutes after transhepatic arterial embolization. MRI was performed at 7 d after the treatment to assess the distribution of SPIO in the SPIO-DOX group and SPIO-DOX-LIP group, while CT was performed to assess the distribution of LIP in the DOX-LIP group and SPIO-DOX-LIP group. All the rabbits were sacrificed and their livers were removed at 7 d after treatment for the detection of tissue DOX level. The histopathologic examinations were performed including HE staining, Prussian blue staining and TUNEL assay, and then the tumor necrosis percentage and apoptosis index were calculated.? Results: Compared to the DOX group, the levels of AST and ALT in other 3 groups were significantly elevated at 1 and 3 d after embolization (P<0.05). The levels of ALT and AST in the DOX group, DOX-LIP group or SPIO-DOX-LIP group returned to the baseline at day 7, there were no significant differences (P>0.05). The SPIO-DOX-LIP group exhibited the lowest serum DOX level at all time points up to 120 minutes after embolization (P<0.05). However, the tissue DOX level in the SPIO-DOX-LIP group was the highest among all groups at day 7 (P<0.05). The SPIO-DOX group and SPIO DOX-LIP group showed significantly lower MRI signal intensity of tumors in T2 weighted imaging (T2WI) at day 7. Meanwhile DOX-LIP group and SPIO-DOX-LIP group showed that high-density lipiodol was deposited in the tumors in CT images. Histopathologic findings showed an almost complete central necrosis coagulation of tumors in the SPIO-DOX-LIP group, and the tumor necrosis percentage and tumor apoptosis index were significantly increased in the SPIO-DOX-LIP group compared to those in other 3 groups (P<0.05).? Conclusion: This novel drug-delivery system of SPIO nano-drug carrier together with LIP is safe and feasible when it is used for transhepatic arterial embolization for liver tumor. It provides an excellent MR and CT visualization and improves the therapeutic efficacy for the treatment of rabbit VX2 liver tumor. PMID- 29187651 TI - [Comparison of effects between IL-2 and IL-7 on glutamic acid decarboxylase 65 reactive T cell responses in patients with Type 1 diabetes]. AB - OBJECTIVE: To explore the type of cytokine (IL-2 or IL-7) and its most optimal concentration regarding the improvement of the signal-to-noise ratio of glutamic acid decarboxylase 65 (GAD65) in enzyme-linked immunospot (ELISPOT) assay in Type 1 diabetic (T1DM) patients.? Methods: Twenty T1DM patients (Group A) and sixteen healthy controls matched with age and sex (Group B) were enrolled in our study, and their peripheral blood mononuclear cells (PBMCs) were isolated by Ficoll method. GAD65, internal control and Pediacel served as "five-for-one" vaccine were selected as the stimulating antigen. Different concentrations of IL-2 [0 U/mL (Group 1), 0.5 U/mL (Group 2), 2.5 U/mL (Group 3) and 12.5 U/mL (Group 4)] were added to the culture system. The CD4+ T cells of secreting interferon-gamma (IFN-gamma) in the above groups were determined by ELISPOT. The spots number, net values and stimulating index (SI) were compared in GAD65 (signal) and internal control (background). Next, another 21 T1DM patients (Group C)and 12 healthy controls matched with age and sex (Group D) were enrolled, and the specific T cell response to the GAD65 antigen was detected. The net values and SI were compared between the best optimal concentration of IL-2 (2.5 U/mL, Group 5) and IL-7 (0.5 ng/mL, Group 6).? Results: 1) After adding IL-2 into the Group A, the amount of GAD65 reactive T cells in different groups increased compared with Group A1, while the background in the internal control also increased gradually with the increased concentration of IL-2. There was no significant difference in net value (signal-noise) in the different concentration between the Group A3 and the Group A4 (P>0.05). The SI in the Group A3 (2.8), the highest one, was significantly higher than that in the Group B3 (1.3) (P<0.05). 2) Although the number of GAD65 spots in the Group C6 and the Group D6 were slightly higher than that in the Group C5 and the Group D5, respectively, the background in the Group C6 and the Group D6 also increased, without statistical significance (P>0.05). The mean net value spot and SI in the Group C5 (net value: 5.5; SI: 2.8) were both significantly higher than those in the Group C6 (net value: 4.3; SI: 1.8) (both P<0.05).? Conclusion: The concentration of 2.5 U/mL for IL-2 is proved to be the best optimal concentration for GAD65 specific T-cell responses in ELISPOT in patients with T1DM. IL-2 is much better than IL-7 in improvement of the SI in the ELISPOT. PMID- 29187652 TI - [Cordyceps sinensis protects HK2 cells from ischemia-reperfusion injury through Sirt1 pathway]. AB - OBJECTIVE: To investigate the effects of Cordyceps sinensis (CS) on cellular apoptosis and Sirt1 expression in HK2 cells followed by ischemia-reperfusion (I/R).? Methods: HK2 cells were incubated with different concentrations of CS (10, 20, 40, 80, 160, 320 mg/L) for 24 hours, and the optimal concentration of CS was selected by measuring cell proliferation. The confluent HK2 cells were incubated with 0.01 MUmol/L antimycin A for 2 hours to induce ischemia in vitro, and then the reperfusion was achieved by incubating cells with glucose-replete complete growth medium for 24 hours. HK2 cells were divided into 4 groups: a control group, an I/R group, an I/R+CS (160 mg/L) group, and an I/R+CS (160 mg/L)+Sirtinol (25 MUmol/L) group. Twenty-four hours later, total RNA and protein were collected. The cell proliferation was evaluated by MTT assay; the mRNA and protein expression of Sirt1 and the cleaved caspase-3 were measured by qRT-PCR and Western blot, respectively. The cellular apoptosis rate was determined by Annexin V-FITC/PI double staining and flow cytometry.? Results: Certain concentrations (10-160 mg/L) of CS did not show effect on the proliferation of HK2 cells (P>0.05), while 320 mg/L of CS inhibited cell proliferation significantly (P<0.01); compared with the control group, the mRNA and protein expressions of Sirt1 and the cleaved caspase-3 in the I/R group were up-regulated (P<0.01) and the apoptosis rate was extremely high; compared with the I/R group, CS significantly up-regulated Sirt1 mRNA and protein expression (P<0.01) while down-regulated cleaved caspase-3 mRNA and protein levels (P<0.01), and reduced apoptosis rate (P<0.05). The effects of CS were blocked in the presence of sirtinol, an inhibitor of CS.? Conclusion: CS protects HK2 cells from I/R injury through activation of Sirt1 pathway.

AB - OBJECTIVE: To investigate the status of vascular access in hemodialysis patients in our center.? Methods: The general information of hemodialysis patients and types and complications of vascular access at Xiangya Hospital of Central South University from April 2015 to April 2016, were retrospectively analyzed.? Results: Among 258 prevalent patients, 87.60% of them had arteriovenous fistula (AVF), while 12.40% showed tunneled cuffed catheter. Of the 61 incident patients, 80.33% of them initiated dialysis with a non-tunneled and non-cuffed catheter, 8.19% with an AVF, 9.84% with a tunneled cuffed catheter, and 1.64% with needle puncture. The types of AVF access included 76.55% of wrist radiocephalic fistula, 7.08% of mid-forearm cephalic fistula, 11.06% of elbow brachiocephalic fistula, and 5.31% of antecubital fistula and transposed basilic fistula. Seventy-seven (34.07%) patients with AVF suffered complications and wherein aneurysms accounted for 24.34%.? Conclusion: In maintenance hemodialysis patients, autologous AVF is the prevalent vascular access. In the beginners for dialysis, non-tunneled and non-cuffed catheter are their choice. Additional efforts and incentives may be necessary to improve vascular access during the initiation of hemodialysis.

Methods: The data of 104 children with ocular MG from June 2010 to March 2014 were collected from Department of Pediatric Neurology of Xiangya Hospital and they were retrospectively studied. The patients were divided into 3 groups: a methylprednisolone group (n=44), a prednisone group (n=48) and a bromine pyridostigmine group (n=12). Evaluative system from American MG foundation was used to evaluate the efficacy of treatment and the ratio of ocular MG transformed into systematic MG.? Results: The efficacy in the methylprednisolone group was better than that in the prednisone group, and both of them were better than that in the bromine pyridostigmine group (both P<0.05).Methylprednisolone, prednisone combined with bromine pyridostigmine could reach a better long-term efficacy in children with ocular MG. Early treatment with glucocorticoid could reduce clinical relapse.? Conclusion: A treatment with high-dose methylprednisolone pulse can improve early clinical remission in children with ocular MG. However, there is a similar efficacy in the long run of different glucocorticoid therapeutic regiments. A relatively order onset age, infection and thyroid dysfunction are recurrent risk factors in children with ocular MG.

AB - OBJECTIVE: To explore the imaging measurement and clinical significance of the angle between the axis of pedicle and the plane of lamina in lower cervical vertebra.? Methods: Three dimensional reconstruction of CT scan was performed in 30 patients with cervical deformity, and the angle between the axis of pedicle and the plane of lamina was measured with the specific reconstructed CT image of C3-C7.? Results: 1) The left and right transverse angle of C3-C7 between the axis of pedicle and the ipsilateral plane of lamina were 98.3 degrees +/-6.3 degrees , 98.0 degrees +/-5.1 degrees , 97.5 degrees +/-6.9 degrees , 95.1 degrees +/-5.0 degrees , 85.8 degrees +/-5.4 degrees and 96.7 degrees +/-8.2 degrees , 98.7 degrees +/-7.1 degrees , 97.8 degrees +/-3.6 degrees , 93.2 degrees +/-6.2 degrees , 86.8 degrees +/-5.7 degrees , respectively, which showed a gradual decreasing trend. Meanwhile the angle of C3-C6 was more than 90 degrees and C7 was less than 90 degrees. In addition to C6 with C3 and C7 with other segments, the rest of the differences between the sections was not statistically significant (all P>0.05). 2) The left and right transverse angle of C3-C7 between the axis of pedicle and the pedicle of vertebral arch of lamina were 0.2 degrees +/-4.5 degrees , 1.2 degrees +/-7.2 degrees , -0.8 degrees +/-6.8 degrees , -3.3 degrees +/-5.4 degrees , -14.7 degrees +/-4.0 degrees and -1.6 degrees +/-5.4 degrees , 1.9 degrees +/-4.6 degrees , -0.5 degrees +/-6.0 degrees , -4.6 degrees +/-5.3 degrees , -13.7 degrees +/-3.4 degrees , respectively, which showed a first increasing and then reducing trend. Meanwhile the angle of C4 was maximum angle. In addition to C6 with C3, C6 with C4, and C7 with other segments, the differences between the sections was not statistically significant (all P>0.05). 3) The left and right sagittal angle of C3-C7 between the axis of pedicle and the ipsilateral plane of lamina were 77.7 degrees +/-7.6 degrees , 77.0 degrees +/ 7.1 degrees , 85.3 degrees +/-8.4 degrees , 94.1 degrees +/-2.2 degrees , 94.9 degrees +/-3.8 degrees and 78.5 degrees +/-7.1 degrees , 76.2 degrees +/-6.2 degrees , 86.4 degrees +/-6.4 degrees , 94.0 degrees +/-2.7 degrees , 95.6 degrees +/-3.8 degrees , respectively, which showed a gradual increasing trend. The angle of C3-C4 was less than 90 degrees. C5 showed large variation and C6-C7 was more than 90 degrees. In addition to C3 with C4 and C6 with C7, the differences between the sections was statistically significant (all P<0.05). There was no significant difference between the two sides of the above indexes (all P>0.05).? Conclusion: In low cervical vertebra, there is a certain angle relationship between the axis of pedicle and the plane of lamina, which can provide reference for the clinical determination of angle of pedicle screw insertion.

AB - OBJECTIVE: To observe the clinical parameters and short-term prognosis of Tibetan high-altitude area children with congenital heart disease undergoing surgery and anaesthesia in low-altitude area, and to investigate the perioperative safety of the treatment.? Methods: From January, 2016 to December, 2016, 14 children with congenital heart disease who underwent surgery were assigned into 2 groups (n=7 each): the high-altitude area group (X group, children from Tibetan Autonomous Region) and the low-altitude area group (H group, children from Hunan Province). Echocardiography data, perioperative hemodynamic changes, postoperative recovery, complication and perioperative serum N terminal pro B type natriuretic peptide (NT-proBNP) levels were recorded.? Results: There were no significant differences in cardiac structure and function between the 2 groups, while the incidence of pulmonary hypertension in the X group was significantly higher than that in the H group (P<0.05). There were no significant differences in perioperative hemodynamics between the 2 groups (P>0.05), while the duration in ICU in the X group was longer than that in the H group and the serum NT-proBNP level in the X group was higher than that in the H group (P<0.05).? Conclusion: For children with congenital heart disease in Tibetan high-altitude area, undergoing surgery in low-altitude area contributes to a steady perioperative hemodynamics and helps to increase the perioperative safety. There may be a higher risk of postoperative cardiac dysfunction in Tibetan children than that in low-altitude area. PMID- 29187657 TI - [Based on empirical research: a preliminary study on application of the social aging scale for healthy people]. AB - OBJECTIVE: To build a social aging scale for healthy people, and get the accuracy and feasibility of the scale to judge the aging of healthy people on the basis of the empirical research.? Methods: Stratified random sampling was conducted according to the nine different age groups, and the age-related social function information was collected for healthy people by using the scale, which was made in our own plant; the distribution of the score, the correlations between the score and age or telomere length were analyzed by statistical software.? Results: A total of 2 297 subjects were collected for the analysis. The ratio of male to female was 0.8:1. Social function of aging score was in the range of 3.00-12.90; aging score of personal ability was in the range of 1.00-4.45; aging score of social participation was in the range of 1.00-4.52; and aging score of organizational communication was in the range of 1.00-5.00. The correlation coefficient of aging scores with age was 0.696 (P<0.001). The result of telomere length showed that the relative telomere length was 1.056+/-0.261. The telomere length in different groups were significantly different (F=35.803, P<0.001). The telomere length was negatively correlated with aging (r=-0.964, P<0.001) and social function of aging (r=-0.857, P<0.001), respectively.? Conclusion: The scores of age-related social function, personal ability, social participation, and organizational communication are increased with age. The telomere length is negatively correlated to aging score. The scale is applicable to measure social function of aging, which can provide reference for evaluation of the comprehensive of aging.

AB - OBJECTIVE: To estimate the status of pregnancy complications among women with polycystic ovary syndrome (PCOS) through a systematic review of published literatures.? Methods: Systematic literature searches were conducted in PubMed, Web of Science, Medline, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, Weipu and China Biology Medicine disc (CBMdisc), as well as the relevant articles published from inception to April 1st 2017, which reported the prevalence of pregnancy complications among women with PCOS. Random effective models were used to calculate pooled prevalence and 95% confidence intervals. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of those included studies. Subgroup analyses were used to evaluate the influence of overweight/obesity and insulin resistance before pregnancy on the estimates of pregnancy complications among women with PCOS.? Results: Fifty-nine studies involving 13 378 PCOS women and 49 395 non-PCOS women were included. Among women with PCOS, pooled estimates were 20.26% for gestational diabetes mellitus, 13.94% for hypertensive disorder of pregnancy, 64.16% for caesarean section, 13.35% for preterm birth, 9.84% for macrosomia, 5.88% for low birth weight, 5.25% for early gestational age, 8.45% for late gestational age, 1.93% for neonatal malformations, 0.88% for perinatal mortality and 3.71% for neonatal asphyxia. And the estimates of gestational diabetes mellitus, hypertensive disorder of pregnancy, caesarean section, preterm birth, macrosomia and neonatal asphyxia among women with PCOS were significantly higher than those in women without PCOS (all P<0.05). Subgroup analysis showed the estimates of gestational diabetes mellitus, macrosomia and late gestational age among PCOS women who were overweight/obesity before pregnancy were significant higher than those among PCOS women with normal BMI (all P<0.05); and compared to PCOS women without insulin resistance prior to pregnancy, PCOS women with pre-pregnancy insulin resistance were at an increased risk for gestational diabetes mellitus, preterm birth and macrosomia (all P<0.05).? Conclusion: PCOS in pregnancy is associated with high rates of pregnancy complications. It is an important risk factor for pregnancy complications.

NMDAR affects the occurrence and development of cardiovascular disease such as hypertension, arrhythmia, myocardial infarction. PMID- 29187661 TI - [Inflammation-relevant mechanisms for postoperative cognitive dysfunction and the preventive strategy]. AB - Postoperative cognitive dysfunction (POCD) is thought to be a mild cognitive disorder. It means that patients without cognitive diseases before surgery suffer from subtle changes in psychomotility, personality, social skills and cognitive function after the surgery. A decline in memory is the core characteristics of these symptoms. POCD is mainly seen in the elderly people following surgery. It can prolong hospital stay, reduce quality of life, increase mortality, and thus aggravate the burden of public health. It is urgent to take precautions to reduce the incidence. The precise mechanism of POCD remains unclear. Previous studies have shown that inflammation plays an important role in it. Sterile surgery can result in peripheral inflammation. Through several pathways, the signals from the peripheral immune response were sent to central system. Due to the individual difference, the degree of the central neuroinflammation was also heterogeneous. Some inflammations may lead to the occurrence of POCD. In order to prevent POCD, we should focus on the anti-inflammatory therapy. PMID- 29187662 TI - [Primary culture of human normal epithelial cells]. AB - The traditional primary culture methods of human normal epithelial cells have disadvantages of low activity of cultured cells, the low cultivated rate and complicated operation. To solve these problems, researchers made many studies on culture process of human normal primary epithelial cell. In this paper, we mainly introduce some methods used in separation and purification of human normal epithelial cells, such as tissue separation method, enzyme digestion separation method, mechanical brushing method, red blood cell lysis method, percoll layered medium density gradient separation method. We also review some methods used in the culture and subculture, including serum-free medium combined with low mass fraction serum culture method, mouse tail collagen coating method, and glass culture bottle combined with plastic culture dish culture method. The biological characteristics of human normal epithelial cells, the methods of immunocytochemical staining, trypan blue exclusion are described. Moreover, the factors affecting the aseptic operation, the conditions of the extracellular environment, the conditions of the extracellular environment during culture, the number of differential adhesion, and the selection and dosage of additives are summarized.

AB - The value of snake venom polypeptides in clinical application has drawn extensive attention, and the development of snake polypeptides into new drugs with anti tumor, anti-inflammatory, antithrombotic, analgesic or antihypertensive properties has become the recent research hotspot. With the rapid development of molecular biology and biotechnology, the mechanisms of snake venom polypeptides are also gradually clarified. Numerous studies have demonstrated that snake venom polypeptides exert their pharmacological effects by regulating ion channels, cell proliferation, apoptosis, intracellular signaling pathway, and expression of cytokine as well as binding to relevant active sites or receptors.

AB - OBJECTIVE: To investigate the pathophysiology, clinical manifestation and neuroimaging characteristics and therapeutic experiences for hemichore associated with non-ketotic hyperglycemia (HC-NH).? Methods: Clinical data of three patients with HC-NH from Xiangya Hospital, Central South University were analyzed retrospectively, and the related literature was reviewed.? Results: The core clinical features of HC-NH were characterized by acute/subacute onset of hemichorea with non-ketotic hyperglycemia in the elderly females. Radiologic findings associated with HC-NH were characterized by hyperattenuation on computed tomographic (CT) scans and hyperintensity on T1-weighted magnetic resonance imaging (MRI) at unilateral basal ganglion region. Blood glucose control was the foundation of treatment. Dopamine receptor antagonists and benzodiazepine sedative were helpful in controlling hemichorea. ? Conclusion: Hemichorea hemiballismus is a rare complication of nonketotic hyperglycaemia in elderly type 2 diabetes. It is associated with contralateral striatal radiological abnormality and typically T1 hyperintensity on MRI. The pathophysiology of HC-NH is not clear. The prognosis of HC-NH is favorable. Antidiabetic drugs combined with dopamine receptor antagonists can effectively relieve the hemichorea symptoms.

AB - Subcutaneous panniculitis-like T cell lymphoma (SPTCL) is a very rare form of peripheral alpha/beta T cell skin lymphoma that is localized primarily in the subcutaneous adipose tissues. It is characterized by single or multiple painful subcutaneous nodules or lumps, often affecting the limbs. The patient presented to the Department of Dermatology, Second Xiangya Hospital, Central South University, who suffered from intermittent fever and erythema on the body, finally was diagnosed as SPTCL after histopathological examinations for twice. PMID- 29187666 TI - Impact of Objective Malnutrition Status on the Clinical Outcomes in Patients With Peripheral Artery Disease Following Endovascular Therapy. AB - BACKGROUND: Peripheral artery disease (PAD) is an athero-occlusive disease and a known risk factor for cardiovascular events. The controlling nutritional status (CONUT) score and geriatric nutritional risk index (GNRI) are objective tools for evaluating malnutrition and are reportedly associated with poor clinical outcomes in patients with fatal diseases. However, the effect of malnutrition on the clinical outcomes in patients with PAD remains unclear.Methods and Results:We enrolled 357 patients with PAD who underwent endovascular therapy. Malnutrition was diagnosed by CONUT score and GNRI as in previous reports. During a median follow-up period of 1,071 days, there were 67 major adverse cardiovascular and leg events (MACLEs). The CONUT score- and GNRI-based malnutrition statuses were identified in 56% and 46% of the patients, respectively. Proportion of malnutrition increased with advancing Fontaine class. The multivariate Cox proportional hazard regression analysis demonstrated that both the CONUT score- and GNRI-based malnutrition status was an independent predictor of MACLEs. The Kaplan-Meier analysis demonstrated that the MACLE ratio increased with deteriorating malnutrition. Finally, the addition of the CONUT score or GNRI to the known risk factors significantly improved the net reclassification index and integrated discrimination index. CONCLUSIONS: Malnutrition was common and closely associated with the clinical outcomes in patients with PAD, indicating that it is a novel therapeutic target in the management of these patients. PMID- 29187667 TI - Strategy and Outcome of Catheter Ablation for Persistent Atrial Fibrillation - Impact of Progress in the Mapping and Ablation Technologies. AB - Pulmonary vein (PV) antrum isolation (PVAI) is effective in treating paroxysmal atrial fibrillation (AF) but is less so for persistent AF. A recent randomized study on the ablation strategies for persistent AF demonstrated that 2 common atrial substrate modifications, creation of linear lesions in the left atrium and ablation of complex fractionated electrogram sites, in addition to PVAI did not improve the outcome compared with stand-alone PVAI, suggesting the necessity of a more individualized, selective approach to persistent AF. There are emerging technologies, including high-resolution mapping with the use of multi-electrode catheter and auto mapping system and contact force (CF) guide ablation; the former allows rapid and accurate confirmation of the completeness of PVAI, and the latter enhances the achievement of durable ablation lesions more securely. Ablation for fibrotic area(s) has been proposed as a new approach for substrate modification, and high-resolution mapping is useful to define the area with low voltage electrograms, a surrogate marker for atrial fibrosis. Ablation for non-PV triggers in addition to PVAI improves the outcome of persistent AF. Further, durable isolation of the left atrial posterior wall may reduce AF recurrence. These ablation strategies with concomitant use of the emerging technologies are strongly expected to enhance the effectiveness of catheter ablation for persistent AF. PMID- 29187668 TI - Exploring Risk Factors of Patient Falls: A Retrospective Hospital Record Study in Japan. AB - Patient falls are common adverse medical events in hospitals. The objectives of this study were to clarify the factors of patient falls at hospitalization or transfer to another ward, which could be assumed that patients experience new environment. Patients who were hospitalized or transferred to another ward at a hospital in Japan, between January 14 and February 14, 2014 were included. We used a risk assessment sheet and applied stepwise regression analysis to identify factors of patient falls. We also investigated changes in patient conditions on the risk assessment sheet by the chi-square test. A total of 1,362 patients (53.2% female; mean age, 57.1 +/- 18.0 years) were eligible for analysis, and 38 (2.8%) fell during the study period. The fallers were significantly older than the non-fallers (63.8 +/- 18.0 vs. 56.9 +/- 18.7 years, P = 0.03), but no significant difference was seen in sex (55.3% vs. 53.1% female). "History of falls", "Tubes inserted", "Need assistance/supervision for toileting" and "Excretion more than two times per night" were significantly related to patient falls (adjusted odds ratios [95% confidence interval]: 2.41 [1.05-5.53], 3.64 [1.57-8.43], 4.52 [2.00-10.23] and 3.92 [1.38-11.09]). Among 30 fallers, "Overestimation or non-understanding of own physical abilities" was significantly more frequent after falls (30.0%) than before falls (6.7%, P = 0.02). The factors found in this study might be useful for identifying patients at higher risk of falls. PMID- 29187669 TI - Usefulness of the Combination of Tuberculin Skin Test and Interferon-Gamma Release Assay in Diagnosing Children with Tuberculosis. AB - Japan is still designated as a medium incidence country, worldwide. Although the definitive diagnosis of tuberculosis is made by detecting pathogen from tissue specimens, collecting those from children is physically difficult. Therefore, we must frequently depend on the results of tuberculin skin test (TST) or interferon gamma release assay (IGRA). However, the value of IGRA in diagnosing tuberculosis in infants remains unclear. We implemented TST and IGRA concurrently and examined the significance of combining these two tests by analyzing cases where conflicting results were evident from other tests. Subjects included 52 children (24 boys, 28 girls) age 15 years or younger (4.0 +/- 3.4 years) who visited our hospital for close examination after medical checkup for tuberculosis contact tracing. The children underwent TST, T-SPOT(r).TB, chest plain radiography, and chest computed tomography with a view to tuberculosis diagnosis during a 26 months period from January 2013 to March 2015. T-SPOT results were positive in 9/52 cases (17.3%), and TST results were positive in 12/52 cases (23.1%). Conflicting results were observed in 7/52 cases (13.5%), and all cases were treated as latent tuberculosis infection or incident cases of tuberculosis. The value of T-SPOT in tuberculosis diagnosis in children is still being established. However, there are a number of cases where conflicting results for T-SPOT and TST are indicated. Thus, it is currently desirable to use T-SPOT and TST concomitantly for children at an early age, especially for children below the age of 5 years, as a diagnostic measure in complementing other techniques. PMID- 29187670 TI - Differential Development of Facial and Hind Paw Allodynia in a Nitroglycerin Induced Mouse Model of Chronic Migraine: Role of Capsaicin Sensitive Primary Afferents. AB - Despite the relatively high prevalence of migraine or headache, the pathophysiological mechanisms triggering headache-associated peripheral hypersensitivities, are unknown. Since nitric oxide (NO) is well known as a causative factor in the pathogenesis of migraine or migraine-associated hypersensitivities, a mouse model has been established using systemic administration of the NO donor, nitroglycerin (NTG). Here we tried to investigate the time course development of facial or hindpaw hypersensitivity after repetitive NTG injection. NTG (10 mg/kg) was administrated to mice every other day for nine days. Two hours post-injection, NTG produced acute mechanical and heat hypersensitivity in the hind paws. By contrast, cold allodynia, but not mechanical hypersensitivity, occurred in the facial region. Moreover, this hindpaws mechanical hypersensitivity and the facial cold allodynia was progressive and long-lasting. We subsequently examined whether the depletion of capsaicin-sensitive primary afferents (CSPAs) with resiniferatoxin (RTX, 0.02 mg/kg) altered these peripheral hypersensitivities in NTG-treated mice. RTX pretreatment did not affect the NTG-induced mechanical allodynia in the hind paws nor the cold allodynia in the facial region, but it did inhibit the development of hind paw heat hyperalgesia. Similarly, NTG injection produced significant hindpaw mechanical allodynia or facial cold allodynia, but not heat hyperalgesia in transient receptor potential type V1 (TRPV1) knockout mice. These findings demonstrate that different peripheral hypersensitivities develop in the face versus hindpaw regions in a mouse model of repetitive NTG-induced migraine, and that these hindpaw mechanical hypersensitivity and facial cold allodynia are not mediated by the activation of CSPAs. PMID- 29187671 TI - Bavachin Induces Apoptosis through Mitochondrial Regulated ER Stress Pathway in HepG2 Cells. AB - As a traditional herbal medicine, the fruits of Psoralea corylifolia L. (Fructus Psoraleae (FP)) have been widely used for the treatment of various skin diseases for hundred years. Recently, the emerging FP-induced toxic effects, especially hepatotoxicity, in clinic are getting the public's attention. However, its exact toxic components and mechanisms underlying remain unclear. Bavachin, one of flavonoids in FP, has been documented as a hepatotoxic substance, and the present study aimed to determine the toxicity caused by bavachin and the possible toxic mechanisms involved using human hepatocellular carcinoma (HepG2) cells. Our results showed that bavachin could significantly inhibited cell proliferation and trigger the endoplasmic reticulum (ER) stress in a dose dependent manner. Downregulating ER stress using tauroursodeoxycholic acid (TUDCA) obvious attenuated bavachin-triggerd cell apoptosis. Then, small interfering RNA (siRNA) knock-down of Mitofusion2 (Mfn2) resulted in a remarkable aggravation of ER stress through the inhibition of the phosphorylation of protein kinase B (Akt). Additionally, suppression of reactive oxygen species (ROS) by ROS Scavenger (N acetyl-l-cystein (NAC)) also reduced bavachin-induced ER stress. Taken together, our study demonstrated that bavachin-induced ER stress caused cell apoptosis by Mfn2-Akt pathway, and that ROS may participate upstream in this mechanism. Here, we not only provide a new understanding of ROS/Mfn2/Akt pathway in bavachin induced cytotoxicity via the ER stress, but also identify a new specific intervention to prevent FP-induced hepatotoxicity in the future. PMID- 29187672 TI - Clinical Characteristics and Low Susceptibility to Daptomycin in Enterococcus faecium Bacteremia. AB - Enterococcus faecium has high levels of resistance to multiple antibiotics, and the mortality due to E. faecium bacteremia is high. Accordingly, E. faecium strains with low susceptibility to daptomycin are a concern in clinical practice. This study assessed the predictive factors and prognosis of patients with bacteremia due to E. faecium as well as the antimicrobial susceptibility, particularly to daptomycin, among E. faecium isolates. The medical records of patients admitted to Osaka City University Hospital with E. faecalis (n = 60) and E. faecium (n = 48) bacteremia between January 2011 and March 2016 were retrospectively reviewed. The E. faecalis group (mean age: 62.0 years) included 22 women, and the E. faecium group (mean age: 59.1 years) included 19 women. Predictive factors for infection, prognosis, and isolate antimicrobial susceptibilities were evaluated. The mean Sequential Organ Failure Assessment score and mortality rate did not differ between the two groups. The independent predictors of E. faecium bacteremia in multivariate analysis included quinolone use (p = 0.025), malignancy (p = 0.021), and prolonged hospitalization (p = 0.016). Cardiovascular disease was associated with a reduced risk of E. faecium bacteremia (p = 0.015). Notably, the percentage of E. faecium isolates with low daptomycin susceptibility was higher than that of E. faecalis (8.5% vs. 0%, p = 0.036). Thus, E. faecium should be considered when administering antibiotic therapy to patients with a history of these predictors. Furthermore, the use of daptomycin should be avoided in case of E. faecium with low susceptibility to daptomycin. PMID- 29187673 TI - Dietary interventions to prevent and manage diabetes in worksite settings: a meta analysis. AB - OBJECTIVES: The translation of lifestyle intervention to improve glucose tolerance into the workplace has been rare. The objective of this meta-analysis is to summarize the evidence for the effectiveness of dietary interventions in worksite settings on lowering blood sugar levels. METHODS: We searched for studies in PubMed, Embase, Econlit, Ovid, Cochrane, Web of Science, and Cumulative Index to Nursing and Allied Health Literature. Search terms were as follows: (1) Exposure-based: nutrition/diet/dietary intervention/health promotion/primary prevention/health behavior/health education/food /program evaluation; (2) Outcome-based: diabetes/hyperglycemia/glucose/HbA1c/glycated hemoglobin; and (3) Setting-based: workplace/worksite/occupational/industry/job/employee. We manually searched review articles and reference lists of articles identified from 1969 to December 2016. We tested for between-studies heterogeneity and calculated the pooled effect sizes for changes in HbA1c (%) and fasting glucose (mg/dl) using random effect models for meta-analysis in 2016. RESULTS: A total of 17 articles out of 1663 initially selected articles were included in the meta-analysis. With a random-effects model, worksite dietary interventions led to a pooled -0.18% (95% CI, -0.29 to -0.06; P<0.001) difference in HbA1c. With the random-effects model, the interventions resulted in 2.60 mg/dl lower fasting glucose with borderline significance (95% CI: -5.27 to 0.08, P=0.06). In the multivariate meta-regression model, the interventions with high percent of female participants and that used the intervention directly delivered to individuals, rather the environment changes, were associated with more effective interventions. CONCLUSION: Workplace dietary interventions can improve HbA1c. The effects were larger for the interventions with greater number of female participants and with individual level interventions. PMID- 29187675 TI - Scientific base for the Japanese Stress Check Program. PMID- 29187674 TI - Nitrative DNA damage in cultured macrophages exposed to indium oxide. AB - OBJECTIVES: Indium compounds are used in manufacturing displays of mobile phones and televisions. However, these materials cause interstitial pneumonia in exposed workers. Animal experiments demonstrated that indium compounds caused lung cancer. Chronic inflammation is considered to play a role in lung carcinogenesis and fibrosis induced by particulate matters. 8-Nitroguanine (8-nitroG) is a mutagenic DNA lesion formed during inflammation and may participate in carcinogenesis. To clarify the mechanism of carcinogenesis, we examined 8-nitroG formation in indium-exposed cultured cells. METHODS: We treated RAW 264.7 mouse macrophages with indium oxide (In2O3) nanoparticles (primary diameter: 30-50 nm), and performed fluorescent immunocytochemistry to detect 8-nitroG. The extent of 8 nitroG formation was evaluated by quantitative image analysis. We measured the amount of nitric oxide (NO) in the culture supernatant of In2O3-treated cells by the Griess method. We also examined the effects of inhibitors of inducible NO synthase (iNOS) and endocytosis on In2O3-induced 8-nitroG formation. RESULTS: In2O3 significantly increased the intensity of 8-nitroG formation in RAW 264.7 cells in a dose-dependent manner. In2O3-induced 8-nitroG formation was observed at 2 h and further increased at 4 h, and the amount of NO released from In2O3 exposed cells was significantly increased at 2-4 h compared with the control. 8 NitroG formation was suppressed by 1400W (an iNOS inhibitor), methyl-beta cyclodextrin and monodansylcadaverine (inhibitors of caveolae- and clathrin mediated endocytosis, respectively). CONCLUSIONS: These results suggest that endocytosis and NO generation participate in indium-induced 8-nitroG formation. NO released from indium-exposed inflammatory cells may induce DNA damage in adjacent lung epithelial cells and contribute to carcinogenesis. PMID- 29187676 TI - Three-Channeled Aortic Dissection in a Patient without Marfan Syndrome. AB - A 64-year-old man was admitted for evaluation of back pain. He did not have a Marfan syndrome (MFS)-like appearance, and had a history of a type B aortic dissection and total arch replacement. A connective tissue disorder had been suspected because of the histologic findings of the resected aortic wall. On admission, a computed tomography (CT) scan demonstrated a three-channeled aortic dissection (3ch-AD) measuring 63 mm in diameter. We planned to perform elective surgery during his hospitalization. On the fourth hospital day, he complained of severe back pain, and enhanced CT scan revealed an aortic rupture. The patients with 3ch-AD often have MFS. However, even if they do not have an MFS-like appearance, clinicians should consider fragility of the aortic wall in patients with 3ch-AD. If the aortic diameter is enlarged, early surgery is recommended. In particular, if a connective tissue disorder is obvious or suspected, emergent surgery is warranted.

AB - Although the technology of endovascular aortic repair (EVAR) for abdominal aortic aneurysm (AAA) is evolving that make it appealing for challenging anatomy, proximal aortic neck morphology, especially severe angulation, is still one of the most determinants for a successful procedure. We describe a patient of AAA with severely angulated proximal neck, in whom kinked stent graft limb occurred against severe angulation of proximal neck. Then, we suggested how to prevent this complication in the second patient. Our case demonstrated the stent graft limb could be kinked by severe aortic neck angulation, making it challenging. However, the kinked stent graft limb could be prevented by deploying stent graft limbs below the most severely angulated aortic neck intentionally.

AB - INTRODUCTION: We investigated the additive value of the 3T 3D constructive interference in steady state (CISS) sequence to conventional MRI for the evaluation of spinal dural arteriovenous fistulae (SDAVF). MATERIALS AND METHODS: We included 16 consecutive patients (15 men, 1 woman; age range 42-81 years; mean 64 years) with SDAVF who underwent 3T MRI and digital subtraction angiography (DSA) before treatment. Two neuroradiologists independently evaluated the presence of abnormal vessels on 3D CISS-, T2- and T1-weighted images (T1WI, T2WI), and contrast-enhanced T1WI using a 3-point grading system. Interobserver agreement was assessed by calculating the kappa coefficient. RESULTS: The SDAVF site was the cervical region in one patient, the thoracic region in 12 patients, the lumbar region in two, and the sacral region in one. For the visualization of abnormal vessels, the mean score was significantly higher for 3D CISS than the other sequences (P < 0.05). In 12 of 16 cases (75%) both readers made definite positive findings on additional 3D-CISS images. Interobserver agreement was excellent for 3D CISS images (kappa = 1.0), good for T1WI (kappa = 0.78; 95% confidence interval [CI] 0.54-1.00) and T2WI (kappa = 0.74; 95% CI 0.48-1.00) and moderate for contrast-enhanced T1WI (CET1WI) (kappa = 0.50; 95% CI 0.21-0.80). CONCLUSION: For the assessment of abnormal vessels of SDAVF, the 3T 3D CISS sequence adds value to conventional MRI.

AB - PURPOSE: A correlation mapping technique delineating delay time and maximum correlation for characterizing pulsatile cerebrospinal fluid (CSF) propagation was proposed. After proofing its technical concept, this technique was applied to healthy volunteers and idiopathic normal pressure hydrocephalus (iNPH) patients. METHODS: A time-resolved three dimensional-phase contrast (3D-PC) sampled the cardiac-driven CSF velocity at 32 temporal points per cardiac period at each spatial location using retrospective cardiac gating. The proposed technique visualized distributions of propagation delay and correlation coefficient of the PC-based CSF velocity waveform with reference to a waveform at a particular point in the CSF space. The delay time was obtained as the amount of time-shift, giving the maximum correlation for the velocity waveform at an arbitrary location with that at the reference location. The validity and accuracy of the technique were confirmed in a flow phantom equipped with a cardiovascular pump. The technique was then applied to evaluate the intracranial CSF motions in young, healthy (N = 13), and elderly, healthy (N = 13) volunteers and iNPH patients (N = 13). RESULTS: The phantom study demonstrated that root mean square error of the delay time was 2.27%, which was less than the temporal resolution of PC measurement used in this study (3.13% of a cardiac cycle). The human studies showed a significant difference (P < 0.01) in the mean correlation coefficient between the young, healthy group and the other two groups. A significant difference (P < 0.05) was also recognized in standard deviation of the correlation coefficients in intracranial CSF space among all groups. The result suggests that the CSF space compliance of iNPH patients was lower than that of healthy volunteers. CONCLUSION: The correlation mapping technique allowed us to visualize pulsatile CSF velocity wave propagations as still images. The technique may help to classify diseases related to CSF dynamics, such as iNPH.

AB - Resistant starch is not digestible in the small intestine and is fermented by lactic acid bacteria in the large intestine into short chain fatty acids, such as acetate, propionate and butyrate, which result in several health benefits in analogy with dietary fibre components. The mode and mechanism of resistant starch degradation by lactic acid bacteria is still not understood. In the present study, we have purified alpha-D-glucosidase from Lactobacillus fermentum NCDC 156 by employing three sequential steps i.e. ultra filtration, DEAE-cellulose and Sephadex G-100 chromatographies. It was found to be a monomeric protein (~50 kDa). The optimum pH and temperature of this enzyme were found to be 5.5 and 37 degrees C, respectively. Under optimised conditions with p-nitrophenyl-D glucopyranoside as the substrate, the enzyme exhibited a Km of 0.97 mM. Its activity was inhibited by Hg2+ and oxalic acid. N-terminal blocked purified enzyme was subjected to lysyl endopeptidase digestion and the resultant peptides were subjected to BLAST analysis to understand their homology with other alpha-D glucosidases from lactobacillus species. PMID- 29187681 TI - Identification of YbhA as the pyridoxal 5'-phosphate (PLP) phosphatase in Escherichia coli: Importance of PLP homeostasis on the bacterial growth. AB - The gene ybhA of Escherichia coli encodes a phosphatase that has an in vitro specificity to dephosphorylate pyridoxal 5'-phosphate (PLP or vitamin B6), a co factor for aminotransferases and other enzymes. In this study, we found that excess pyridoxal (PL) in a minimal medium resulted in excess PLP in vivo and growth inhibition, which was alleviated by YbhA overproduction. Conversely, the YbhA overproduction resulted in PLP shortage in vivo and the correlated reduction in growth rate, which was significantly negated by PL in the medium. In addition, the overproduction of a PL kinase, PdxK or PdxY, was inhibitory to cell growth only in the absence of the functional ybhA gene, and the growth defects were alleviated by casamino acids in the medium, which suggested that both the shortage of, and excess, PLP resulted in the disturbance of amino acid metabolism and cell growth, as revealed by a metabolome analysis. PMID- 29187682 TI - Bacterial glycerol oxidation coupled to sulfate reduction at neutral and acidic pH. AB - Glycerol is a main co-product of biodiesel production. Crude glycerol may serve as a cheap and attractive substrate in biotechnological applications, e.g. for the production of valuable chemicals or as an electron donor for reduction processes. In this work, sulfate reduction with glycerol was studied at neutral and acidic pH using bioreactor sludge samples and Tinto River sediments as a source of inoculum, respectively. Communities of sulfate-reducing bacteria (SRB) and fermentative bacteria were co-enriched at both pH values. Molecular analyses revealed that sequences belonging to Desulfomicrobium genus were dominant in the cultures enriched at pH 7, while Desulfosporosinus sequences dominated in the culture enriched at pH 4. Glycerol conversion was coupled to sulfate reduction, but the substrate was incompletely oxidized to acetate in the neutrophilic enrichments, and acetate, lactate, and 1,3-propanediol under low pH conditions. Two strains belonging to Desulfomicrobium and Proteiniphilum genera were isolated from the neutrophilic enrichments, but the first isolate was not able to use glycerol, which suggests a syntrophic relationship between glycerol-degrading fermentative bacteria and SRB. A Clostridium strain able to grow with glycerol was isolated from the low pH enrichment. Our data indicate that glycerol promotes the growth of sulfate-reducing communities to form sulfide, which can be used to precipitate and recover heavy metals. PMID- 29187683 TI - [Efficacy of high-dose steroid pulse therapy for anti-galactocerebroside antibody positive combined central and peripheral demyelination]. AB - A 59-year-old man had been admitted to another hospital because of diplopia and thirst at the beginning of March and was diagnosed with diabetic ketoacidosis. He was referred to our hospital because he had limb weakness, dysarthria, and bilateral sensory impairment of the upper limbs, which worsened rapidly from the middle of March, although plasma glucose had been well controlled after the initiation of insulin therapy in the previous hospital. Contrast spinal MRI in our hospital revealed hyperintense lesions at the level of C4 to C5 and T10. The level of myelin basic protein was high (1,260 pg/ml) in the cerebrospinal fluid and serum anti-neurofascin antibody was negative. Nerve conduction study showed typical findings of demyelination at least 2 regions. Although anti-neurofascin antibody was negative, he was diagnosed with combined central and peripheral demyelination (CCPD) based on these clinical findings. After the repeated methylprednisolone pulse therapy for five times, the hyperintense lesions of the spinal cord disappeared gradually. He was bedridden at the beginning of his hospitalization but could ambulate with a cane on discharge 2 months after the admission. Then we received the result of anti-galactocerebroside antibody test as positive. This case suggested that high-dose steroid pulse therapy is safe and may be effective for anti-galactocerebroside antibody-positive CCPD. PMID- 29187684 TI - [A case of hereditary sensory and autonomic neuropathy type 1E with frontal lobe dysfunction as an initial symptom]. AB - A 49-year-old man had developed gradually personality change, gait disturbance, and hearing loss for five years. On admission, he presented with frontal release signs, stuttering, vertical gaze palsy, sensorineural deafness, muscle rigidity, ataxia, and sensory disturbance with areflexia in the lower extremities. Brain MRI demonstrated atrophy in the cerebellum and midbrain tegmentum as well as cerebral atrophy, predominantly in the frontal lobe. He was tentatively diagnosed as progressive supranuclear palsy on the basis of clinical features and imagings. On nerve conduction study, no sensory nerve action potentials were elicited in the upper and lower extremities. Details of family history revealed a hereditary sensory neuropathy with autosomal dominant inheritance in his relatives. Because genetic analysis showed a rare missense mutation (c.1483T>C, p.Y495H) in DNA methyltransferase 1 gene, we diagnosed him as having hereditary sensory and autonomic neuropathy type 1E (HSAN1E). In addition, p.M232R mutation in prion protein gene was detected. It should be kept in mind that there are some patients with HSAN1E presenting with frontal lobe dysfunction as an initial symptom and with clinical features mimicking progressive supranuclear palsy. PMID- 29187685 TI - [A case of subarachnoid hemorrhage due to infective endocarditis by methicillin resistant coagulase-negative staphylococcus]. AB - A 77-year-old man visited our hospital with unstable gait following 2 months of anorexia. Brain MRI showed multiple infarcts; cardiac echocardiography revealed mitral-valve vegetation; and blood culture revealed methicillin-resistant coagulase-negative staphylococci. The patient was diagnosed with infective endocarditis (IE). Subarachnoid hemorrhage (SAH) developed ten days after antibiotic treatment. Intracranial aneurysm was not found. We speculated that chronic inflammation of the cerebral arterial walls by bacteria of low virulence was associated with SAH complication. The vegetation disappeared following additional gentamicin administration and the patient recovered to walk. PMID- 29187686 TI - [Portal-systemic encephalopathy with bilateral thalamic and internal capsule lesions using diffusion-weighted MRI in a super-aged patient]. AB - We describe the case of a 90-year-old woman who was hospitalized in July 2016 and subsequently experienced a sudden decline in consciousness level resulting in a state of deep coma. Involuntary movements were not observed, and bilateral Babinski signs were inconclusive. Diffusion-weighted MRI (DWI) of the brain showed bilateral hyperintensity in the thalamus and internal capsule, laboratory testing detected high levels of plasma ammonia, and an electroencephalogram showed delta waves and triphasic waves predominantly in the frontal lobe. Based on these results, treatment for hepatic encephalopathy was administered, which led to an improvement in consciousness level, a decrease in plasma ammonia levels, and a normalization in the DWI scan. Abdominal computed tomography scan showed no abnormality in the liver, but revealed an abnormal blood vessel leading from the ileocolic vein to the inferior vena cava; the patient was diagnosed with portal-systemic encephalopathy. In deep coma patients, acute encephalopathy with hyperammonemia is important for differential diagnosis when DWI shows high density legions in the thalamus and internal capsule. PMID- 29187687 TI - [Symmetrical lesions of the cerebral peduncles and internal capsules on MRI in a patient with extranodal NK/T cell lymphoma]. AB - A 72-year-old man was admitted to our hospital because of subacute progressive consciousness disturbance. FLAIR images showed diffuse high intensity areas in the bilateral thalamus, basal ganglia, and white matter. Chest CT revealed a mass in the right lung. The patient was diagnosed with extranodal natural killer/T cell lymphoma (ENKL) according to the results of a biopsy of the right pulmonary mass. The FLAIR images showed diffuse white matter lesions, without a mass such as lymphomatosis cerebri. On diffusion-weighted images, symmetrical high intensity lesions of the cerebral peduncle and the internal capsule suggested high-density lymphoma cells around neurons. ENKL of the central nervous system and lung is a very rare neoplasm, and this case showed characteristic images. PMID- 29187688 TI - [Progressive dysarthria and bilateral sensory disturbance in a case of bilateral ventrolateral pontine infarction]. AB - A rare case of bilateral ventrolateral pontine infarction in a 70-year-old man who developed progressive dysarthria and bilateral sensory disturbance is reported with literature review. He had been diagnosed with hypertension, dyslipidemia, and impaired glucose tolerance 10 years earlier. Ten days before admission, he was aware of the difficulty in walking and speaking, which gradually worsened. On admission he showed bilateral thermal hypoalgesia of face and lower extremities, dysarthria, dysphagia, and ataxic gait. High resolution three-dimensional MRI revealed bilateral ventrolateral pontine infarction with a large atherosclerotic plaque in the ventral side of the basilar artery, which led to a diagnosis of atherothrombotic brain infarction. The atherosclerotic plaque in the basilar artery was thought to be responsible for simultaneous occlusion of the bilateral short circumflex arteries of the pons. PMID- 29187689 TI - [A case of leptomeningeal melanomatosis with acute paraplegia and multiple cranial nerve palsies]. AB - A 62-year-old man with acute paraplegia was transferred to our hospital. He had flaccid paraplegia and multiple cranial nerve palsies, such as mydriasis of the left pupil, abduction palsy of the left eye, hoarseness and dysphagia, but no meningeal irritation signs. MRI of the spinal canal showed swellings of the conus medullaris and the cauda equine, and also contrast enhancement of the spinal meninges. The cerebrospinal fluid (CSF) showed pleocytosis and protein increment. The lymph node was swollen in his right axilla. The biopsy specimen from the right axillary lymph node revealed metastasis of malignant melanoma histologically. Careful check-up of his whole body found a malignant melanoma in the subungual region of the right ring finger. Repeated cytological examination revealed melanoma cells in the CSF, confirming the diagnosis of leptomeningeal melanomatosis. His consciousness was gradually deteriorated. His family members chose supportive care instead of chemotherapy or surgical therapy after full information about his conditions. Finally, he died 60 days after transfer to our hospital. This is a rare case of leptomenigeal melanomatosis presenting with acute paraplegia and multiple cranial nerve palsies. Careful follow-up and repeated studies are vital for the early diagnosis of leptomenigeal melanomatosis in spite of atypical clinical presentation. PMID- 29187690 TI - [Treatment for paroxysmal sympathetic hyperactivity in amyotrophic lateral sclerosis patient]. AB - We report a case of an 80-year-old man who contracted amyotrophic lateral sclerosis (ALS) 15 years ago, was put on a ventilator 8 years ago, and became locked in 3 years ago. Two years ago, he began to suffer from sudden symptoms of paroxysmal sympathetic hyperactivity (PSH) attacks (hot flushes, abnormal sweating, tachycardia, and increased blood pressure). One day, he developed multiple-organ failure. This failure healed in a few days, but PSH attacks remained. His catecholamine levels were abnormal: adrenaline, 215 pg/ml; noradrenaline, 5,960 pg/ml; and dopamine, 606 pg/ml. Diazepam was administered, which decreased both the number of PSH attacks and the catecholamine levels. When the dose was increased to 3 mg, the attacks stopped, whereas when the dose was reduced to 2 mg, the attacks relapsed. When the dose of 3 mg was continued, there was no relapse of the attacks and no re-rise in the catecholamine levels. These results show that diazepam alone has an effect on PSH attacks in ALS. PMID- 29187691 TI - [Tapia's syndrome following transesophageal echocardiography during an open-heart operation: a case report]. AB - A 67-year-old man presented with hoarseness, dysarthria and deviation of the tongue to the left side the day after the open-heart operation under general anesthesia. Brain MRI demonstrated no causal lesion, and laryngoscope showed left vocal cord abductor palsy, so we diagnosed him with Tapia's syndrome (i.e., concomitant paralysis of the left recurrent and hypoglossal nerve). His neurological symptoms recovered gradually and improved completely four months after the onset. Tapia's syndrome is a rare condition caused by the extra cranial lesion of the recurrent laryngeal branch of the vagus nerve and the hypoglossal nerve, and mostly described as a complication of tracheal intubation. In this case, transesophageal echo probe has been held in the left side of the pharynx, so compression to the posterior wall of pharynx by the probe resulted in this condition, and to the best of our knowledge, this is the first report of Tapia's syndrome due to transesophageal echocardiography during an open-heart operation. This rare syndrome should be considered as a differential diagnosis of dysarthria and tongue deviation after a procedure associated with compression to the pharynx. PMID- 29187692 TI - Nitrate Supply-Dependent Shifts in Communities of Root-Associated Bacteria in Arabidopsis. AB - Root-associated bacterial communities are necessary for healthy plant growth. Nitrate is a signal molecule as well as a major nitrogen source for plant growth. In this study, nitrate-dependent alterations in root-associated bacterial communities and the relationship between nitrate signaling and root-associated bacteria in Arabidopsis were examined. The bacterial community was analyzed by a ribosomal RNA intergenic spacer analysis (RISA) and 16S rRNA amplicon sequencing. The Arabidopsis root-associated bacterial community shifted depending on the nitrate amount and timing of nitrate application. The relative abundance of operational taxonomic units of 25.8% was significantly changed by the amount of nitrate supplied. Moreover, at the family level, the relative abundance of several major root-associated bacteria including Burkholderiaceae, Paenibacillaceae, Bradyrhizobiaceae, and Rhizobiaceae markedly fluctuated with the application of nitrate. These results suggest that the application of nitrate strongly affects root-associated bacterial ecosystems in Arabidopsis. Bulk soil bacterial communities were also affected by the application of nitrate; however, these changes were markedly different from those in root-associated bacteria. These results also suggest that nitrate-dependent alterations in root-associated bacterial communities are mainly affected by plant-derived factors in Arabidopsis. T-DNA insertion plant lines of the genes for two transcription factors involved in nitrate signaling in Arabidopsis roots, NLP7 and TCP20, showed similar nitrate-dependent shifts in root-associated bacterial communities from the wild-type, whereas minor differences were observed in root-associated bacteria. Thus, these results indicate that NLP7 and TCP20 are not major regulators of nitrate-dependent bacterial communities in Arabidopsis roots. PMID- 29187693 TI - A Simple and Efficient RNA Extraction Method from Deep-Sea Hydrothermal Vent Chimney Structures. AB - RNA-based microbiological analyses, e.g., transcriptome and reverse transcription quantitative PCR, require a relatively large amount of high quality RNA. RNA based analyses on microbial communities in deep-sea hydrothermal environments often encounter methodological difficulties with RNA extraction due to the presence of unique minerals in and the low biomass of samples. In the present study, we assessed RNA extraction methods for deep-sea vent chimneys that had complex mineral compositions. Mineral-RNA adsorption experiments were conducted using mock chimney minerals and Escherichia coli total RNA solution, and showed that detectable RNA significantly decreased possibly due to adsorption onto minerals. This decrease in RNA was prevented by the addition of sodium tripolyphosphate (STPP), deoxynucleotide triphosphates (dNTPs), salmon sperm DNA, and NaOH. The addition of STPP was also effective for RNA extraction from the mixture of E. coli cells and mock chimney minerals when TRIzol reagent and the RNeasy column were used, but not when the RNeasy PowerSoil total RNA kit was used. A combination of STPP, TRIzol reagent, the RNeasy column, and sonication resulted in the highest RNA yield from a natural chimney. This indirect extraction procedure is simple, rapid, inexpensive, and may be used for large scale RNA extraction. PMID- 29187694 TI - Efficacy and Safety of Pitavastatin in Children and Adolescents with Familial Hypercholesterolemia in Japan and Europe. AB - AIM: Children with Familial Hypercholesterolemia (FH) are widely prescribed statins, and it has been suggested that the effects of statins differ among ethnicities. We compared the efficacy and safety of pitavastatin in children and adolescents with FH in clinical trials conducted in Japan and Europe. METHODS: Low-density lipoprotein cholesterol (LDL-C) reductions, adjusted for confounding factors, and safety were compared between the studies in Japan and Europe. In the Japanese study, 14 males with heterozygous FH, aged 11.8+/-1.6 years, were randomized to 52-week double-blind treatment with 1 or 2 mg/day pitavastatin. In the European study, 106 children and adolescents with high risk hyperlipidemia (103 heterozygous FH), aged 10.6+/-2.9 years, were randomized to 12-week double blind treatment with 1, 2 or 4 mg/day pitavastatin or placebo; 84 of these patients and 29 new patients participated in a 52-week open-label extension study. RESULTS: Age, body weight and baseline LDL-C were identified as factors influencing LDL-C reduction. There were no significant differences in the adjusted mean percentage reduction in LDL-C in Japanese and European children by pitavastatin (24.5% and 23.6%, respectively at 1 mg/day and 33.5% and 30.8%, respectively at 2 mg/day). Pitavastatin was well tolerated without any difference in the frequency or nature of adverse events between the treatment groups, or between the studies. CONCLUSION: There were no significant differences between the efficacy or safety of pitavastatin in Japanese and European children and adolescents with FH, suggesting no relevant ethnic differences in the safety or efficacy of pitavastatin. PMID- 29187695 TI - MicroRNA-21-Regulated Activation of the Akt Pathway Participates in the Protective Effects of H2S against Liver Ischemia-Reperfusion Injury. AB - Maintaining a certain level of hydrogen sulfide (H2S) in ischemia-reperfusion (I/R) is essential for limiting injury to the liver. Exogenous H2S exerts protective effects against this injury, but the mechanisms remain unclear. Liver injury was induced in Wistar rats undergoing hepatic I/R for 30 min, followed by a 3-h reperfusion. Administration of GYY4137 (a slow-releasing H2S donor) significantly attenuated the severity of liver injury and was reflected by reduced inflammatory cytokine production and cell apoptosis, the levels of which were elevated by I/R, while DL-propargylglycine (PAG, an inhibitor of cystathionine gamma-lyase [CSE]) aggravated liver injury. Delivery of GYY4137 significantly elevated the plasma levels of H2S and upregulated the expression of microRNA-21 (miR-21), leading to the activation of the Akt pathway, in rat livers subjected to I/R. To further investigate the protective mechanisms of H2S during liver I/R injury, we established a cell model of hypoxia/reoxygenation (H/R) by incubating Buffalo rat liver (BRL) cells under hypoxia for 4 h followed by normoxia for 10 h. The regulatory effect of miR-21 on the Akt pathway by downregulating phosphatase and tensin homolog (PTEN) was validated by luciferase assays. Incubation of sodium hydrosulfide (NaHS), an H2S donor, increased the expression of miR-21, attenuated the reduced cell viability and the increased apoptosis by H/R, in BRL cells. Anti-miR-21 abolished the protective effects of NaHS by inactivating the Akt pathway. In conclusion, the present results indicate the activation of the Akt pathway regulated by miR-21 participates in the protective effects of H2S against I/R-induced liver injury. PMID- 29187696 TI - Accuracy of follicle count and ovulation confirmation using magnetic resonance imaging in microminipigs with normal estrus cycles. AB - Magnetic resonance imaging (MRI) is suggested to be useful for counting follicles and confirming ovulation in microminipigs. However, its accuracy is unknown. We have compared the number of follicles counted by MRI to that of corpus hemorrhagicum confirmed directly by visual inspection. The follicles of 17 microminipigs were counted by using ovarian MRI on a 0.4 Tesla MRI System every 24 hr after estrus until follicle images disappeared. Then, we performed laparotomy to count their corpus hemorrhagicum. Significant correlation was observed between follicle counts obtained using MRI (5.18 +/- 1.78 per head) and the numbers of corpus hemorrhagicum (5.47 +/- 1.74 per head). In conclusion, follicle counts using 0.4-T MRI were reliable, and confirmed microminipig ovulation. PMID- 29187697 TI - Synthesis, characterization and in vitro release performance of the pegylated valnemulin prodrug. AB - Valnemulin, successfully developed by Sandoz in 1984, is a new generation derivative of pleuromutilin related to tiamulin. Valnemulin has low water solubility, a short half-life period, low bioavailability, and instability. The application of valnemulin was restricted. Therefore, finding a more moderate delivery system is necessary to improve the shortcomings of valnemulin. The purpose of the study was to improve the strong stability and the irritation caused by of valnemulin hydrochloride power through pegylated-valnemulin prodrug mode. The prepared pegylated-valnemulin prodrug was characterized and evaluated by in vitro release performance under buffer solutions with pH levels of 7.4 and 3.6. The loading rate of valnemulin in PEG-succinic-valnemulin prodrug was determined by ultraviolet spectrophotometer and high performance liquid chromatography (HPLC). HPLC with evaporative light scattering detector was applied to determine the amount of PEG-succinic acid. The loading rate of valnemulin in PEG-succinic-valnemulin prodrug was 6.46%. PEG-succinic-valnemulin prodrug demonstrated a satisfactory solubility of valnemulin with 523 mg.ml-1 and excellent stability verified by the stability experiment. The result of the in vitro release test showed that the prepared PEG-valnemulin prodrug has controlled release ability and the release rate of valnemulin from PEG-valnemulin prodrug with a pH of 7.4 was 64.98%, which was higher than that of pH3.6 with release rate of 31.90%. Therefore, the prepared PEG-succinic-valnemulin prodrug has great application potential. PMID- 29187698 TI - Evaluation of Schistosoma japonicum thioredoxin peroxidase-1 as a potential circulating antigen target for the diagnosis of Asian schistosomiasis. AB - Asian schistosomiasis caused by Schistosoma japonicum is a serious zoonotic disease endemic in China, the Philippines and parts of Indonesia. Mass drug administration in endemic areas resulted to decline in disease severity and intensity. The low intensity of infection limits the use of current parasitological methods for schistosomiasis diagnosis. Detection of parasite circulating antigens might provide more informative result as it may indicate the true status of infection. In this study, S. japonicum thioredoxin peroxidase-1 (SjTPx-1) a 22 kDa secreted antioxidant enzyme expressed throughout the life stages of the parasite was evaluated for its potential use as a biomarker for schistosomiasis japonica infection. Rabbit polyclonal antibody and mouse monoclonal antibodies (mAbs) were raised against the recombinant SjTPx-1 (rSjTPx 1). The antibodies produced against the recombinant antigen was confirmed to detect the native SjTPx-1 in crude adult worm lysate. Likewise, the specific binding of mAbs to parasite TPx-1 and not to mammalian peroxiredoxin-1 orthologues was also confirmed. The double antibody sandwich ELISA developed in this study was able to detect at least 1 ng/ml of rSjTPx-1. In addition, this method was able to detect the antigen from all serum samples of experimentally infected rabbit and mice. The diagnostic potential of SjTPx-1 in human clinical samples was also evaluated, in which 4 out of 10 stool-confirmed serum samples had detectable levels of the antigen. The results suggest that SjTPx-1 can be a potential biomarker for Asian zoonotic schistosomiasis. PMID- 29187699 TI - Establishment of an Alzheimer's disease model with latent herpesvirus infection using PS2 and Tg2576 double transgenic mice. AB - A relationship between Alzheimer's disease and herpes simplex virus infection has been pointed out. We established a model of Alzheimer's disease with a latent herpesvirus infection using a mouse model of Alzheimer's disease (PS2Tg2576) and examined the changes in amyloid beta (Abeta) in the brain. We crossbred female PS2 mice with male Tg2576 hemi mice and chose PS2Tg2576 mice. After priming 5 week-old male mice with anti-pseudorabies virus swine serum, we challenged the mouse with 100 LD50 of YS-81, a wild-type strain of pseudorabies virus. The viral DNA was detected in nasal swabs by a reactivation test and in the trigeminal ganglia. At two months after infection, the Abeta40 and Abeta42 levels in the brains of the mice of the latently infected group were increased; the increase was greater than that observed in the noninfected group. Latent pseudorabies virus infection was established in PS2Tg2576 mice and the level of Abeta increased with the reactivation of the latent virus. PMID- 29187701 TI - Association between Concomitant Use of Acyclovir or Valacyclovir with NSAIDs and an Increased Risk of Acute Kidney Injury: Data Mining of FDA Adverse Event Reporting System. AB - Nonsteroidal anti-inflammatory drugs (NSAIDs) are likely to be used concomitantly with acyclovir or valacyclovir in clinical practice, but the study on the safety of such combinations was seldom reported. The objective of the study was to investigate reports of acute kidney injury (AKI) events associated with the concomitant use of oral acyclovir or valacyclovir with an NSAID by using the United States Food and Drug Administration (FDA) Adverse Event Reporting System (AERS) database between January 2004 and June 2012. The frequency of AKI events in patients while simultaneously taking either acyclovir or valacyclovir and an NSAID was compared using the Chi-square test. The effect of concomitant use of acyclovir or valacyclovir and individual NSAIDs on AKI was analyzed by the reporting odds ratio (ROR). The results showed that AKI was reported as the adverse event in 8.6% of the 10923 patients taking valacyclovir compared with 8.7% of the 2556 patients taking acyclovir (p=NS). However, AKI was significantly more frequently reported in patients simultaneously taking valacyclovir and an NSAID (19.4%) than in patients simultaneously taking acyclovir and an NSAID (10.5%) (p<0.01). The results also suggested that increased risk of AKI was likely associated with the concomitant use of valacyclovir and some NSAIDs such as loxoprofen, diclofenac, etodolac, ketorolac, piroxicam or lornoxicam. The case series from the AERS indicated that compared with acyclovir, valacyclovir is more likely to be affected by NSAIDs, and the concomitant use of valacyclovir with some NSAIDs might be associated with increased risk of AKI. The drug interactions with this specific combination of medications are worth exploring further. PMID- 29187700 TI - Sevoflurane preconditioning ameliorates lipopolysaccharide-induced cognitive impairment in mice. AB - Systemic inflammation induces brain neuronal inflammation, in turn causing acute cognitive disorders. Furthermore, neuronal inflammation is one cause of postoperative cognitive disorder (POCD) and delirium. However, no sufficiently established pharmacological treatment is available for neurocognitive inflammation. This study evaluated the possible neuroprotective effects of preconditioning with sevoflurane anesthesia on cognition and neuroinflammatory changes in an animal model of lipopolysaccharide (LPS)-induced systemic inflammation. Adult mice were randomly divided into (1) control, (2) 2% sevoflurane preconditioning for 1 h, (3) intraperitoneal 5 mg/kg LPS injection, and (4) 2% sevoflurane preconditioning for 1 h + LPS injection groups. At 24 h after 5 mg/kg LPS injection, microglial activation based on ionized calcium binding adapter molecule 1 (Iba-1) expression in the hippocampus was determined using immunostaining and immunoblotting. IL-1beta and IL-6 immunoblotting were used as inflammation markers, and beta-site of amyloid precursor protein cleaving enzyme 1 (BACE1) immunoblotting was performed to evaluate amyloid beta-protein (Abeta) accumulation. Long-term cognitive impairment was evaluated using fear conditioning tests. Intraperitoneal LPS increased levels of Iba-1 (150%), inflammation markers (160%), and Abeta accumulation (350%), and sevoflurane preconditioning suppressed these increases. Systemic LPS caused learning deficits. Sevoflurane also maintained long-term memory in mice receiving LPS injection. Sevoflurane preconditioning prevented long-term memory impairment in the mouse model administered systemic LPS by decreasing excessive microglial activation, inflammation, and Abeta accumulation. This study supports the hypothesis that sevoflurane preconditioning might also be beneficial for neuronal inflammation. Sevoflurane might be beneficial for reducing delirium and POCD.

AB - By the end of 2014, China had an elderly population age 60 or over totaling 212 million; this group accounted for 15.5% of the country's total population of 1.37 billion, which means that China has passed the threshold for an aging population. As China's population ages and the disease spectrum changes, nursing services for the elderly must be expanded. Given differences in the health status, financial situation, and family composition of each elderly person, modern society is tending towards individual nursing care for the elderly. Adapting to the changing composition of society by age will present new challenges. PMID- 29187703 TI - Paraganglioma as a risk factor for bone metastasis. AB - Malignant pheochromocytoma (PHEO) and paraganglioma (PGL) (PHEO and PGL: PPGL) are frequently associated with bone metastasis. Bone metastasis requires long term management and may lead to skeletal-related events (SREs) that remarkably reduce patients' quality of life (QOL). The aim of this study was to elucidate the risk factors for developing bone metastasis in patients with PPGL. The medical records of 40 consecutive adult patients with malignant PPGL at the National Hospital Organization Kyoto Medical Center between 2006 and 2016 were reviewed. SREs were defined as pathologic fracture, spinal cord compression, and the need for bone irradiation and/or surgery. PHEO (20/40) and PGL (20/40) were each present in 50% of the patients. Bone was the most frequent site of metastasis, detected in 60% (24/40). Bone metastasis was more frequent in patients with PGL (16/20, 80%) than in patients with PHEO (8/20, 40%) (p = 0.02). Half (12/24) of the patients with bone metastasis had at least one SRE. Extra skeletal invasion of the spine, defined as local infiltration to the surrounding tissue beyond the cortical bone, was more frequently observed in patients with bone metastasis associated with SREs than without them (p = 0.001). Careful follow-up and management are warranted especially in patients with PGL as a risk factor for bone metastasis and with extra-skeletal invasion of the spine as risk factor of SREs.

PMID- 29187705 TI - Overexpression of SMYD3 Is Predictive of Unfavorable Prognosis in Hepatocellular Carcinoma. AB - SET and MYND domain-containing protein 3 (SMYD3) is a kind of histone lysine methyltransferase, responsible for transcriptional activation as a member of an RNA polymerase complex. The ectopic expression of SMYD3 is proved to promote the progress of many kinds of cancers. In hepatocellular carcinoma (HCC), SMYD3 was demonstrated to promote the proliferation and metastasis of HCC cell lines, but the clinical significance of SMYD3 has not been elucidated. In the present study, we detected the expression of SMYD3 in 100 HCC tissues with immunohistochemistry and divided these tissue specimens into high-expression group and low-expression group according to the immunohistochemical score of SMYD3. Importantly, the intensity of SMYD3 immunoreactivity was significantly stronger in HCC tissues than that in adjacent normal tissues. Moreover, high expression levels of SMYD3 were significantly associated with larger tumor size (P = 0.043), suggesting that SMYD3 could promote the proliferation of HCC. Moreover, patients with positive hepatitis B virus infection had higher expression levels of SMYD3 (P = 0.013). With univariate and multivariate analysis, we explored the prognostic significance of SMYD3 in HCC. As a result, high expression levels of SMYD3 were significantly correlated to the poorer clinical outcome of HCC patients (P = 0.009) and were identified as an independent risk factor of HCC for predicting the unfavorable prognosis. In conclusion, overexpression of SMYD3 is an independent prognostic risk of unfavorable prognosis of HCC. We propose that the anti-SMYD3 therapy may be a potential approach to treat HCC. PMID- 29187706 TI - Capturing Early Changes in the Marine Bacterial Community as a Result of Crude Oil Pollution in a Mesocosm Experiment. AB - The results of marine bacterial community succession from a short-term study of seawater incubations at 4 degrees C to North Sea crude oil are presented herein. Oil was used alone (O) or in combination with a dispersant (OD). Marine bacterial communities resulting from these incubations were characterized by a fingerprinting analysis and pyrosequencing of the 16S rRNA gene with the aim of 1) revealing differences in bacterial communities between the control, O treatment, and OD treatment and 2) identifying the operational taxonomic units (OTUs) of early responders in order to define the bacterial gene markers of oil pollution for in situ monitoring.After an incubation for 1 d, the distribution of the individual ribotypes of bacterial communities in control and oil-treated (O and OD) tanks differed. Differences related to the structures of bacterial communities were observed at later stages of the incubation. Among the early responders identified (Pseudoalteromonas, Sulfitobacter, Vibrio, Pseudomonas, Glaciecola, Neptunomonas, Methylophaga, and Pseudofulvibacter), genera that utilize a disintegrated biomass or hydrocarbons as well as biosurfactant producers were detected. None of these genera included obligate hydrocarbonoclastic bacteria (OHCB). After an incubation for 1 d, the abundances of Glaciecola and Pseudofulvibacter were approximately 30-fold higher in the OD and O tanks than in the control tank. OTUs assigned to the Glaciecola genus were represented more in the OD tank, while those of Pseudofulvibacter were represented more in the O tank. We also found that 2 to 3% of the structural community shift originated from the bacterial community in the oil itself, with Polaribacter being a dominant bacterium. PMID- 29187707 TI - Comparison of Prokaryotic and Eukaryotic Communities in Soil Samples with and without Tomato Bacterial Wilt Collected from Different Fields. AB - Biocontrol agents (BCA) effectively suppress soil-borne disease symptoms using natural antagonistic prokaryotes or eukaryotes. The main issue associated with the application of BCA is that disease reduction effects are unstable under different field conditions. In order to identify potentially effective BCA among several fields, we compared prokaryotic and eukaryotic communities in soil with and without tomato bacterial wilt from three different fields, each of which had the same field management and similar soil characteristics. Soil samples were collected from three fields and two depths because bacterial wilt pathogens were present in soil at a depth greater than 40 cm. We classified soil samples based on the presence or absence of the bacterial phcA gene, a key gene for bacterial wilt pathogenicity and tomato disease symptoms. Pyrosequencing of the prokaryotic 16S rRNA gene and eukaryotic internal transcribed spacer region sequences showed that the diversity and richness of the communities mostly did not correlate with disease symptoms. Prokaryotic and eukaryotic community structures were affected more by regional differences than the appearance of disease. Several prokaryotes and eukaryotes were more abundant in soil that lacked disease symptoms, and eight prokaryotes and one eukaryote of this group were commonly detected among the three fields. Some of these taxa were not previously found in disease-suppressive soil. Our results suggest that several prokaryotes and eukaryotes control plant disease symptoms. PMID- 29187708 TI - Library Construction from Subnanogram DNA for Pelagic Sea Water and Deep-Sea Sediments. AB - Shotgun metagenomics is a low biased technology for assessing environmental microbial diversity and function. However, the requirement for a sufficient amount of DNA and the contamination of inhibitors in environmental DNA leads to difficulties in constructing a shotgun metagenomic library. We herein examined metagenomic library construction from subnanogram amounts of input environmental DNA from subarctic surface water and deep-sea sediments using two library construction kits: the KAPA Hyper Prep Kit and Nextera XT DNA Library Preparation Kit, with several modifications. The influence of chemical contaminants associated with these environmental DNA samples on library construction was also investigated. Overall, shotgun metagenomic libraries were constructed from 1 pg to 1 ng of input DNA using both kits without harsh library microbial contamination. However, the libraries constructed from 1 pg of input DNA exhibited larger biases in GC contents, k-mers, or small subunit (SSU) rRNA gene compositions than those constructed from 10 pg to 1 ng DNA. The lower limit of input DNA for low biased library construction in this study was 10 pg. Moreover, we revealed that technology-dependent biases (physical fragmentation and linker ligation vs. tagmentation) were larger than those due to the amount of input DNA. PMID- 29187709 TI - An efficient method for saliva collection from mature pigs to determine their enzymatic and electrolytic profiles. AB - In this study, a novel 'rope-assisted swab method' for the collection of saliva samples from 45 adult pigs was established and validated. This method was efficient for harvesting 2 milliliters or more of saliva from each of the pigs for subsequent analyses within two min. The amount of alpha-amylase and lipase in the collected saliva samples was between 38-6,655 and 2-52 U/l, respectively. For HCO3- and electrolytes, the range was between 9-40, 15-76, 4.3-48.5 and 7-65 mM for HCO3-, Na+, K+ and Cl-, respectively. No significant differences in the enzymatic and electrolytic profiles were observed among sows with a high average litter size (SHA), sows with a low average litter size (SLA) and non-pregnant gilts (NPG) in this study. Our work reveals the efficiency of this collection method for mature pigs, and enzymatic and electrolytic profiling of saliva, which may be a useful reference for multiple diagnostic applications. PMID- 29187710 TI - Hybrid origin of Asian aspermic Fasciola flukes is confirmed by analyzing two single-copy genes, pepck and pold. AB - Nuclear gene markers, phosphoenolpyruvate carboxykinase (pepck) and DNA polymerase delta (pold), have been developed for precise discrimination of Fasciola flukes instead of internal transcribed spacer 1. In this study, these two genes of 730 Fasciola flukes from eight Asian countries were analyzed. The results were compared with their mitochondrial NADH dehydrogenase subunit 1 (nad1) lineages for obtaining a definitive evidence of the hybrid origin of aspermic Fasciola flukes. All the flukes categorized into the aspermic nad1 lineages possessed both the fragment patterns of F. hepatica and F. gigantica (mixed types) in pepck and/or pold. These findings provide clear evidence for the hybrid origin of aspermic Fasciola lineages and suggest that "aspermic Fasciola flukes" should hereafter be called "hybrid Fasciola flukes". PMID- 29187711 TI - Prevalence, genotyping and risk factors of Giardia duodenalis from dogs in Vietnam. AB - This study was carried out to determine the prevalence, genotypes/assemblages and possible risk factors associated with Giardia duodenalis infection in dogs in central Vietnam. A total of 209 dog fecal samples, randomly collected from private owned dogs (n=105) and dogs from stores (n=104), were examined for Giardia cysts by microscopy. Positive samples were genotyped by PCR-sequence analysis of beta-giardin and triosephosphate isomerase genes markers. Risk factors were studied using a structured questionnaire and collected data were analyzed by univariate and multivariate logistic regression analyses. Results indicated that the overall infection rate was 8.6% (18/209) with the detected parasites were belonging to the non-zoonotic assemblages C and D. Age, gender and origin of animals were the main risk factors associated with G. duodenalis infection in dogs under study. Occurrence of infection was more likely in young animals compared to old ones and in females compared to males. Dogs originated from stores were more prone to Giardia infection compared to private owned counterparts. PMID- 29187712 TI - Seroepidemiology of non-primate hepacivirus (NPHV) in Japanese native horses. AB - Non-primate hepacivirus (NPHV) is recently identified as a closely related homologue of hepatitis C virus. The previous studies showed a high prevalence of NPHV infection among Japanese domestic horses originated from abroad. The historical distribution of NPHV among horses in Japan, therefore, is still unknown. In this study, seroepidemiological study of NPHV was conducted using 335 sera from five breeds of Japanese native horses. These horses are maintained as the pedigree and are reared apart from other horse breeds. The detection of antibodies against NPHV were conducted by western blot analysis using the recombinant protein of the NPHV core protein. The antibodies against NPHV were detected in all five breeds, 83 out of 335 (23.4%) horses. These results suggested that NPHV was circulating among Japanese native horses. PMID- 29187714 TI - [Preparation and Biological Characterization of Limulus Factor G-activating Substance of Aspergillus spp.] AB - Aspergillus is a medically important fungal genus that causes a life-threatening infection known as aspergillosis in immunocompromised patients. beta-1,3-Glucan is detected in the plasma of patients with aspergillosis and appears to be useful for the diagnosis of aspergillosis. In this study, we cultured Aspergillus spp. in a chemically defined liquid medium and prepared an Aspergillus water-soluble fraction (ASWS) from the culture supernatants. ASWS was found to be primarily composed of polysaccharides and proteins. Nuclear magnetic resonance analysis suggested that ASWS is a complex carbohydrate, consisting of alpha-1,3-glucan, beta-1,3-glucan, galactomannan, and protein. The ASWS from Aspergillus fumigatus showed limulus factor G activity, whereas zymolyase-treated ASWS did not. ASWS was eliminated from the blood more rapidly than Aspergillus solubilized cell wall beta-glucan. We analyzed the reactivity of human immunoglobulin towards ASWS by an enzyme-linked immunosorbent assay. Anti-ASWS antibodies were detected in human sera, with titers differing among individuals. This study demonstrated that the ASWS corresponds to the limulus factor G-activating substance found in the blood of patients with aspergillosis.

AB - Enterotoxigenic Escherichia coli (ETEC) is primary pathogenic bacteria of piglet diarrhea, over two thirds of piglets diarrhea caused by ETEC are resulted from STa-producing ETEC strains. This experiment was conducted to construct the recombinant E. coli expressing STa and study the injury and mechanism of recombinant E. coli expressing STa on 7 days old piglets colon. Twenty-four 7 days old piglets were allotted to four treatments: control group, STa group (2 * 109 CFU E. coli LMG194-STa), LMG194 group (2 * 109 CFU E. coli LMG194) and K88 group (2 * 109 CFU E. coli K88). The result showed that E. coli infection significantly increased diarrhea rates; changed DAO activity in plasma and colon; damaged colonic mucosal morphology including crypt depth, number of globet cells, density of lymphocytes and lamina propria cell density; substantially reduced antioxidant capacity by altering activities of GSH-Px, SOD, and TNOS and productions of MDA and H2O2; obviously decreased AQP3, AQP4 and KCNJ13 protein expression levels; substantially altered the gene expression levels of inflammatory cytokines. Conclusively, STa group had the biggest effect on these indices in four treatment groups. These results suggested that the recombinant strain expressed STa can induce piglets diarrhea and colonic morphological and funtional damage by altering expression of proteins connect to transportation function and genes associated with intestinal injury and inflammatory cytokines. PMID- 29187715 TI - [A Silkworm Infection Model to Evaluate Antifungal Drugs for Cryptococcosis]. AB - The development of effective drugs against fungal diseases involves performing infection experiments in animals to evaluate candidate therapeutic compounds. Cryptococcus neoformans is a pathogenic fungus that causes deep mycosis, resulting in respiratory illness and meningitis. Here we describe a silkworm system established to evaluate the safety and efficacy of therapeutic drugs against infection by Cryptococcus neoformans and the advantages of this system over other animal models. The silkworm assay system has two major advantages: 1) silkworms are less expensive to rear and their use is less problematic than that of mammals in terms of animal welfare, and 2) in vivo screenings for identifying candidate drugs can be easily performed using a large number of silkworms. The pharmacokinetics of compounds are consistent between silkworms and mammals. Moreover, the ED50 values of antibiotics are concordant between mammalian and silkworm infection models. Furthermore, the body size of silkworms makes them easy to handle in experimental procedures compared with other invertebrate infectious experimental systems, and accurate amounts of pathogens and chemicals can be injected fairly easily. These advantages of silkworms as a host animal make them useful for screening candidate drugs for cryptococcosis. PMID- 29187716 TI - [Possible Involvement of Surface Antigen Protein 2 in the Morphological Transition and Biofilm Formation of Candida albicans]. AB - Surface antigen protein 2 (Csa2) is a member of the Candida albicans Common in Fungal Extracellular Membranes (CFEM) protein superfamily. We previously established its role in iron acquisition in C. albicans. However, the other roles of Csa2 remain unknown. Here, we compared growth, morphological transition, and biofilm formation among wild-type, Csa2-mutant, and complemented strains of C. albicans. Deletion of the Csa2 gene resulted in smaller and reduced colony growth, significant attenuation of the dimorphic transition under serum-inducing conditions, and reduced biofilm formation; complementation restored these levels to those of the wild-type. Our findings demonstrated that Csa2 participated in yeast-to-hyphae morphological switching under serum-inducing conditions and contributed to the biofilm formation of C. albicans. This work, therefore, provides novel insights into the potential roles of Csa2 in virulence of C. albicans. PMID- 29187717 TI - [A Case of Liver Dysfunction Requiring Hospital Admission after Taking Oral Itraconazole for the Treatment of Kerion Celsi]. AB - 67-year-old female patient developed drug-induced liver dysfunction after taking oral itraconazole (ITCZ) for the treatment of kerion celsi. Red papules appeared on the temporal area of the patient one month prior to her visit to our clinic. The patient presented with a nodule with yellow crust, erosion, infiltration, and hair loss on the area. Diagnosis of kerion celsi caused by Trichophyton rubrum was made from clinical, pathological, and mycological findings. Laboratory data showed normal liver function, and the patient was not taking any other medication, thus, daily oral ITCZ 100 mg was started. The skin lesion improved, but severe liver dysfunction was found 1 month after starting ITCZ. Oral ITCZ was therefore terminated, and the patient was admitted to a medical ward for the treatment of liver dysfunction. Hepatobiliary enzymes increased after admission: AST 232 IU/L, ALT 465 IU/L, T-bil 6.1 mg/dL, and D-bil 3.9 mg/dL. The patient was kept at rest and was given oral ursodeoxycholic acid. Hepatobiliary enzymes returned to normal level 2 1/2 months after starting ITCZ. The skin lesion healed without further treatment. No recurrence was observed. It is noteworthy that liver function has to be carefully monitored during treatment with oral ITCZ. PMID- 29187718 TI - [Affinity of Luliconazole for Human Nail Derived Keratin]. AB - Affinity of Luliconazole (LLCZ), an antifungal drug used for topical treatment of onychomycosis in Japan, to nail keratin was demonstrated. Efinaconazole (EFCZ) was used as a reference drug. Drugs at fixed concentrations were added to 4 ml of buffer solution containing 40 mg of nail keratin powder prepared from healthy volunteers or from tinea unguium patients. The mixtures were shaken at 37C, and adsorption and desorption rates of the drug in nail keratin were measured. Theoretical analysis using the Freundlich adsorption isotherm was applied to eliminate effects of testing conditions on the results. Results showed that compared with EFCZ, LLCZ exhibited high adsorption rates and low desorption rates in nail keratins. These results were verified by Freundlich analysis, in which adsorption coefficient (KadsF) and desorption coefficient (KadsF) of LLCZ were 5 7 times and about 2 times higher than EFCZ, respectively. In addition, antifungal activity against Trichophyton rubrum of the desorbed LLCZ samples was determined using disk diffusion assay. In conclusion, LLCZ is considered to possess high affinity to nail keratin. LLCZ, therefore, can be retained in the nail as a reservoir and continuously desorbed at the infection site to exhibit antifungal activity against pathogenic fungi. The pharmacokinetics of LLCZ in the nail is believed to differ from that of EFCZ. As adsorption and desorption rates of the two drugs in nail keratin tended to be different between healthy volunteers and patients, further detailed study is needed. PMID- 29187719 TI - [Small Animal Aspergillosis and Cryptococcosis in Japan]. AB - Canine and feline upper respiratory tract (URT) infection due to Aspergillus spp. is considered an emerging disease, with the number of reported cases continuing to rise in Japan. Aspergillus fumigatus has been the most frequently reported etiologic agent of sino-orbital aspergillosis in dogs and cats; the other Aspergillus species, Aspergillus felis, Aspergillus fischeri, Aspergillus udagawae, Aspergillus viridinutans, and A. fumigatus, have also been implicated in feline cases. The minimum inhibitory concentrations (MICs) of antifungal drugs are elevated for these cryptic species compared with A. fumigatus. Some reports showed that the feline infections due to cryptic species did not respond to treatment with antifungal drugs. These results suggest that species identification and antifungal susceptibility testing of infecting agents are important to ensure effective treatment of feline URT aspergillosis. Feline cryptococcosis in Japan is typically attributed to Cryptococcus neoformans var. grubii. We isolated a fluconazole-resistant strain of C. grubii from a feline cryptococcosis. The predicted amino acid sequence of the lanosterol 14-alpha demethylase gene (ERG11) protein in the isolate was identical to that of the C. grubii reference strain. RT-PCR analysis of ERG11 and ATP binding cassette (ABC) transporter-encoding gene (AFR1) indicated that the isolate had increased transcription factor function for ERG11 and AFR1 compared with fluconazole susceptible strains. This observation, in combination with the lack of resistance to other azoles (that is, lack of cross resistance), suggests that resistance in our isolate was the result of overexpression of the endogenous ERG11 and ABC transporter. Further ecological and epidemiological studies on small animal mycoses in Japan are needed to monitor the emergence of antifungal drug resistant strains. PMID- 29187720 TI - [Histopathological Diagnosis of Fungal Sinusitis and Variety of its Etiologic Fungus]. AB - Fungal sinusitis is divided into two categories depending on mucosal invasion by fungus, i.e., invasive and noninvasive. Invasive fungal sinusitis is further divided into acute and chronic disease based on time course. Noninvasive fungal sinusitis includes chronic noninvasive sinusitis (fungal ball type) and allergic fungal sinusitis. Chronic noninvasive sinusitis is the most predominant fungal sinusitis in Japan, followed by allergic fungal sinusitis. Invasive fungal sinusitis is rare. Hyphal tissue invasion is seen in invasive fungal sinusitis. Acute invasive fungal sinusitis demonstrates hyphal vascular invasion while chronic invasive fungal sinusitis usually does not. Fungal tissue invasion is never found in noninvasive sinusitis. A fungal ball may exist adjacent to sinus mucosa, but its hyphae never invade the mucosa. Fungal balls sometimes contain conidial heads and calcium oxalate, which aid in identifying the fungus in the tissue. Allergic fungal sinusitis is characterized by allergic mucin that is admixed with numerous eosinophils and sparsely scattered fungal elements. Histopathology is important in classifying fungal sinusitis, especially in confirming tissue invasion by the fungus. PMID- 29187721 TI - [Survival Strategies of Aspergillus in the Human Body]. AB - The human body is a hostile environment for Aspergillus species, which originally live outside the human body. There are lots of elimination mechanisms against Aspergillus inhaled into the human body, such as high body temperature, soluble lung components, mucociliary clearance mechanism, or responses of phagocytes. Aspergillus fumigatus, which is the primary causative agent of human infections among the human pathogenic species of Aspergillus, defend itself from the hostile human body environment by various mechanisms, such as thermotolerance, mycotoxin production, and characteristic morphological features. Here we review mechanisms of defense in Aspergillus against elimination from the human body. PMID- 29187723 TI - [Term 16]. PMID- 29187722 TI - [The Plasma (1->3)-beta-D-glucan Assay, a Japanese Contribution to the Diagnosis of Invasive Fungal Infection]. AB - In 1985, a (1->3)-beta-D-glucan assay based on the discovery of a (1->3)-beta-D glucan-sensitive coagulation factor in the horseshoe crab amebocytes was developed in Japan, as a test aid in the diagnosis of invasive fungal infections. After many clinical trials, it has now been incorporated in practice guidelines both in Japan and abroad for the diagnosis and management of invasive fungal infection, and is now available worldwide. In Japan, however, two commercial kits that differ widely in sensitivity to (1->3)-beta-D-glucan are used; namely, the colorimetric and the turbidimetric assays. Thus, attention must be paid when comparing measurement values between the two tests. In most cases, one pg/ml of the latter corresponds to about 7 pg/ml of the former. This raises the cutoff value of the turbidimetric assay far higher than that of the colorimetric assay, raising concern about missing many true cases of invasive fungal infections. The detection limit of the turbidimetric method is equivalent to as high as 60 pg/ml if converted to the colorimetric measurement. Thus, early diagnosis will be difficult to make based on detection of a rise in the beta-D-glucan level in the lower range of concentration. The kits used overseas also differ in sensitivity; thus, global standardization or harmonization will be required to establish inter assay data comparability and to enhance the usefulness of the tests. In the future, genetic engineering may provide an alternative source of the coagulation pathway enzymes other than the horseshoe crabs, in accordance with the global trends in animal protection, and bring about new opportunities for standardization. PMID- 29187724 TI - In-Depth Insight Into the Mechanisms of Cardiac Dysfunction in Patients With Childhood Cancer After Anthracycline Treatment Using Layer-Specific Strain Analysis. AB - BACKGROUND: Anthracycline cardiotoxicity affects clinical outcomes, and its early detection using methods that rely on conventional echocardiography, such as left ventricular ejection fraction (LVEF) is difficult. This study aimed to evaluate the characteristics and the differences in cardiac dysfunction among childhood cancer survivors in 3 age groups using layer-specific strain analysis in a wide age range.Methods and Results:The 56 patients (median age: 15 [range: 6.8-40.2] years) who had been treated with anthracycline for childhood cancer were divided into 3 age groups (C1: 6-12 years, C2: 13-19 years, C3: 20-40 years) after anthracycline treatment, and 72 controls of similar ages were divided into 3 corresponding groups (N1, N2, and N3). Layer-specific longitudinal strain (LS) and circumferential strain (CS) of 3 myocardial layers (endocardium, midmyocardium, and epicardium) were determined using echocardiography. Myocardial damage had not occurred yet in C1. Endocardial CS at the basal level was less in C2 than in N2. Endocardial CS at all levels and midmyocardial CS at the basal and papillary levels were lower in C3 than in N3. LVEF and LS were not significantly different between patients and controls. CONCLUSIONS: Among survivors of childhood cancer, impaired myocardial deformation starts in adolescence and extends from the endocardium towards the epicardium and from the base towards the apex with age. These findings are a novel insight into the time course of anthracycline cardiotoxicity. PMID- 29187725 TI - Mobbing (bullying at work) in Italy: characteristics of successful court cases. AB - BACKGROUND: Mobbing (bullying at work) refers to a form of psychological harassment that occurs in the workplace, in which the victim must be systematically and continuously persecuted for a long period of time. The aim of this work is to analyze the court judgments related to mobbing. METHODS: The data, collected from a website that included judgments from an Italian court, were analyzed according to the literature, identifying the type of victims, consequences, methods of harassment, type of mobbers, and compensation decided by the court. RESULTS: A total of 35 court sentences were analyzed. The findings showed that the duration of the mobbing campaign was on average 1.5 years and that the frequency of harassment was every day in most cases. In the majority of cases (17, 48.6%) the mobbing occurred in a private company. The gender of the victims who reported the mobbing experience was predominantly female (19, 54.3%), and on average, the victims were 44.54 years of age. The victims were classified as captives (12, 34.3%), scapegoats (8, 22.9%), ambitious (8, 22.9%), passives (5, 14.3%) and hypochondriacs (2, 5.7%). The mobbers were predominantly men (25, 71.4%) and on average 53.20 years of age. They were classified as casual (12, 34.3%), sadists (11, 31.4%), instigators (8, 22.9%) and choleric (4, 11.4%). The witnesses were described in the majority of cases as active, while the asymmetry of power was vertical. On average, the victims suffered 4.9 types of harassment, and the most cited consequences were anxiety disorder and physical symptoms. The motives for beginning the mobbing campaign were principally related to difficulties in relationships. The compensation imposed by the court ranged from less than 20,000 to more than 70,000 euros. CONCLUSIONS: The sentences analyzed showed that for different types of victims, there are behaviors, motives and consequences that are linked to different types of perpetrators. PMID- 29187726 TI - Increased levels of interleukin 27 in patients with early clinical stages of non small cell lung cancer. AB - INTRODUCTION Interleukin 27 (IL-27) is a cytokine secreted mostly by antigen presenting cells. It is important for the immune polarization of T helper-1 (Th1) cells, and its role in interstitial lung diseases (ILDs) and lung cancer has been investigated. OBJECTIVES We assessed IL-27 expression in the lower airways of patients with selected ILDs and early-stage non-small cell lung cancer (NSCLC). PATIENTS AND METHODS IL-27 concentrations were examined by an enzyme-linked immunosorbent assay in bronchoalveolar lavage (BAL) fluid supernatants collected from patients with pulmonary sarcoidosis (PS; n = 30), extrinsic allergic alveolitis (EAA; n = 14), idiopathic pulmonary fibrosis (IPF; n = 12), nonspecific interstitial pneumonia (NSIP; n = 14), and NSCLC stages I to IIa (n = 16) with peripheral localization, and in controls (n = 14). The major lymphocyte subsets in BAL fluid were phenotyped, and intracellular IL-27 expression was evaluated by flow cytometry. RESULTS IL-27 concentrations in BAL fluid supernatants were significantly increased in Th1-mediated conditions such as EAA and PS, but not in IPF or NSIP. The highest IL-27 levels (median [SEM], 16.9 [17.5] pg/ml) were reported for NCSLC, and the lowest-for controls (median [SEM], 0.4 [0.2] pg/ml). IL-27 was undetectable in corticosteroid-treated patients with PS. Both CD4+ and CD8+ lymphocytes were positive for IL-27; they were a possible local source of IL-27 because the cytokine levels were positivelysignificantly correlated with the total number of lymphocytes, including CD4+ cells. CONCLUSIONS Our results support the Th1-linked activity of IL-27in ILDs. Early stageNSCLC is characterizedby high IL-27expression in the lower airways. IL-27 is produced by a high percentage of CD4+ and CD8+ cells in BAL fluid, both in patients and controls.

AB - BACKGROUND We explored the expression pattern, prognostic potential, and functional role of microRNA-588 (miR-588) in human breast cancer (BC). MATERIAL AND METHODS The expression pattern of miR-588 was assessed by qPCR in BC cell lines and human BC carcinomas. The correlations between miR-588 and BC patients' clinicopathological characteristics, as well as BC patients' overall survival, were statistically assessed. In in vitro culture, MCF-7 and MDA-MB-231 cells were infected with lentivirus to overexpress endogenous miR-588. The subsequent effects of miR-588 upregulation on BC cell proliferation and cisplatin chemosensitivity were examined. RESULTS miR-588 was found to be significantly downregulated in both BC cell lines and carcinoma tissues of BC patients. Low expression of miR-588 was closely correlated with BC patients' poor prognosis of TNM stage, lymph node metastasis, and estrogen receptor status. In addition, patients with low miR-588-expressing carcinomas had much shorter overall survival. In MCF-7 and MDA-MB-231 cells, lentiviral infection induced significant miR-588 upregulation, and miR-588 upregulation had an anti-tumor effect in BC cells by significantly inhibiting cancer proliferation and increasing cisplatin chemosensitivity. CONCLUSIONS miR-588 is downregulated in BC and its aberrant expression is closely associated with patients' poor prognosis and overall survival, thus suggesting a biomarker role. miR-588 also has anti-tumor function in BC, making it a potential therapeutic target for BC treatment.

AB - BACKGROUND Pleomorphic adenoma is the most common benign tumor arising in the salivary gland. The signs and symptoms of pleomorphic adenoma of the minor salivary glands vary, depending on the anatomical site involved. A rare case of pleomorphic adenoma of the posterior surface of the soft palate is reported that caused sleep disturbance, which was resolved with endoscopic surgical treatment. CASE REPORT A 32-year-old woman experienced snoring and mouth-breathing during sleep. Flexible fiberoptic nasopharyngoscopy imaging of the oropharyngeal passage showed obstruction by a tumor the soft palate, which obstructed the oropharyngeal passage. The tumor was excised using endoscopic-assisted transoral surgery and measure 3*2 cm in diameter. Histopathology showed a benign pleomorphic adenoma of the minor salivary gland. Following surgical excision of the tumor, the patient's sleep improved. CONCLUSIONS To our knowledge, this is the first case of a pleomorphic adenoma of the posterior surface of the soft palate, causing sleep disturbance, removed by endoscopic-assisted transoral surgery following pre operative flexible fiberoptic nasopharyngoscopy imaging of the oropharyngeal passage. PMID- 29187729 TI - Inference of differentiation time for single cell transcriptomes using cell population reference data. AB - Single-cell RNA sequencing (scRNA-seq) is a powerful method for dissecting intercellular heterogeneity during development. Conventional trajectory analysis provides only a pseudotime of development, and often discards cell-cycle events as confounding factors. Here using matched cell population RNA-seq (cpRNA-seq) as a reference, we developed an "iCpSc" package for integrative analysis of cpRNA seq and scRNA-seq data. By generating a computational model for reference "biological differentiation time" using cell population data and applying it to single-cell data, we unbiasedly associated cell-cycle checkpoints to the internal molecular timer of single cells. Through inferring a network flow from cpRNA-seq to scRNA-seq data, we predicted a role of M phase in controlling the speed of neural differentiation of mouse embryonic stem cells, and validated it through gene knockout (KO) experiments. By linking temporally matched cpRNA-seq and scRNA seq data, our approach provides an effective and unbiased approach for identifying developmental trajectory and timing-related regulatory events. PMID- 29187730 TI - Genome-wide analysis in UK Biobank identifies four loci associated with mood instability and genetic correlation with major depressive disorder, anxiety disorder and schizophrenia. AB - Mood instability is a core clinical feature of affective and psychotic disorders. In keeping with the Research Domain Criteria approach, it may be a useful construct for identifying biology that cuts across psychiatric categories. We aimed to investigate the biological validity of a simple measure of mood instability and evaluate its genetic relationship with several psychiatric disorders, including major depressive disorder (MDD), bipolar disorder (BD), schizophrenia, attention deficit hyperactivity disorder (ADHD), anxiety disorder and post-traumatic stress disorder (PTSD). We conducted a genome-wide association study (GWAS) of mood instability in 53,525 cases and 60,443 controls from UK Biobank, identifying four independently associated loci (on chromosomes 8, 9, 14 and 18), and a common single-nucleotide polymorphism (SNP)-based heritability estimate of ~8%. We found a strong genetic correlation between mood instability and MDD (r g = 0.60, SE = 0.07, p = 8.95 * 10-17) and a small but significant genetic correlation with both schizophrenia (r g = 0.11, SE = 0.04, p = 0.01) and anxiety disorders (r g = 0.28, SE = 0.14, p = 0.04), although no genetic correlation with BD, ADHD or PTSD was observed. Several genes at the associated loci may have a role in mood instability, including the DCC netrin 1 receptor (DCC) gene, eukaryotic translation initiation factor 2B subunit beta (eIF2B2), placental growth factor (PGF) and protein tyrosine phosphatase, receptor type D (PTPRD). Strengths of this study include the very large sample size, but our measure of mood instability may be limited by the use of a single question. Overall, this work suggests a polygenic basis for mood instability. This simple measure can be obtained in very large samples; our findings suggest that doing so may offer the opportunity to illuminate the fundamental biology of mood regulation. PMID- 29187732 TI - Structural basis of respiratory syncytial virus subtype-dependent neutralization by an antibody targeting the fusion glycoprotein. AB - A licensed vaccine for respiratory syncytial virus (RSV) is unavailable, and passive prophylaxis with the antibody palivizumab is restricted to high-risk infants. Recently isolated antibodies 5C4 and D25 are substantially more potent than palivizumab, and a derivative of D25 is in clinical trials. Here we show that unlike D25, 5C4 preferentially neutralizes subtype A viruses. The crystal structure of 5C4 bound to the RSV fusion (F) protein reveals that the overall binding mode of 5C4 is similar to that of D25, but their angles of approach are substantially different. Mutagenesis and virological studies demonstrate that RSV F residue 201 is largely responsible for the subtype specificity of 5C4. These results improve our understanding of subtype-specific immunity and the neutralization breadth requirements of next-generation antibodies, and thereby contribute to the design of broadly protective RSV vaccines. PMID- 29187733 TI - Controlling thermal reactivity with different colors of light. AB - The ability to switch between thermally and photochemically activated reaction channels with an external stimulus constitutes a key frontier within the realm of chemical reaction control. Here, we demonstrate that the reactivity of triazolinediones, powerful coupling agents in biomedical and polymer research, can be effectively modulated by an external photonic field. Specifically, we show that their visible light-induced photopolymerization leads to a quantitative photodeactivation, thereby providing a well-defined off-switch of their thermal reactivity. Based on this photodeactivation, we pioneer a reaction manifold using light as a gate to switch between a UV-induced Diels-Alder reaction with photocaged dienes and a thermal addition reaction with alkenes. Critically, the modulation of the reactivity by light is reversible and the individually addressable reaction pathways can be repeatedly accessed. Our approach thus enables a step change in photochemically controlled reactivity, not only in small molecule ligations, yet importantly in controlled surface and photoresist design. PMID- 29187731 TI - Contributions of Zea mays subspecies mexicana haplotypes to modern maize. AB - Maize was domesticated from lowland teosinte (Zea mays ssp. parviglumis), but the contribution of highland teosinte (Zea mays ssp. mexicana, hereafter mexicana) to modern maize is not clear. Here, two genomes for Mo17 (a modern maize inbred) and mexicana are assembled using a meta-assembly strategy after sequencing of 10 lines derived from a maize-teosinte cross. Comparative analyses reveal a high level of diversity between Mo17, B73, and mexicana, including three Mb-size structural rearrangements. The maize spontaneous mutation rate is estimated to be 2.17 * 10-8 ~3.87 * 10-8 per site per generation with a nonrandom distribution across the genome. A higher deleterious mutation rate is observed in the pericentromeric regions, and might be caused by differences in recombination frequency. Over 10% of the maize genome shows evidence of introgression from the mexicana genome, suggesting that mexicana contributed to maize adaptation and improvement. Our data offer a rich resource for constructing the pan-genome of Zea mays and genetic improvement of modern maize varieties. PMID- 29187734 TI - O-GlcNAcylation is required for B cell homeostasis and antibody responses. AB - O-linked N-acetylglucosamine (O-GlcNAc) transferase (Ogt) catalyzes O-GlcNAc modification. O-GlcNAcylation is increased after cross-linking of the B-cell receptor (BCR), but the physiological function of this reaction is unknown. Here we show that lack of Ogt in B-cell development not only causes severe defects in the activation of BCR signaling, but also perturbs B-cell homeostasis by enhancing apoptosis of mature B cells, partly as a result of impaired response to B-cell activating factor. O-GlcNAcylation of Lyn at serine 19 is crucial for efficient Lyn activation and Syk interaction in BCR-mediated B-cell activation and expansion. Ogt deficiency in germinal center (GC) B cells also results in enhanced apoptosis of GC B cells and memory B cells in an immune response, consequently causing a reduction of antibody levels. Together, these results demonstrate that B cells rely on O-GlcNAcylation to maintain homeostasis, transduce BCR-mediated activation signals and activate humoral immunity. PMID- 29187736 TI - Rules for processing genetic data for research purposes in view of the new EU General Data Protection Regulation. AB - Genetic data contain sensitive health and non-health-related information about the individuals and their family members. Therefore, adopting adequate privacy safeguards is paramount when processing genetic data for research or clinical purposes. One of the major legal instruments for personal data protection in the EU is the new General Data Protection Regulation (GDPR), which has entered into force in May 2016 and repealed the Directive 95/46/EC, with an ultimate goal of enhancing effectiveness and harmonization of personal data protection in the EU. This paper explores the major provisions of the new Regulation with regard to processing genetic data, and assesses the influence of such provisions on reinforcing the legal safeguards when sharing genetic data for research purposes. The new Regulation attempts to elucidate the scope of personal data, by recognizing pseudonymized data as personal (identifiable) data, and including genetic data in the catalog of special categories of data (sensitive data). Moreover, a set of new rules is laid out in the Regulation for processing personal data under the scientific research exemption. For instance, further use of genetic data for scientific research purposes, without obtaining additional consent will be allowed, if the specific conditions is met. The new Regulation has already fueled concerns among various stakeholders, owing to the challenges that may emerge when implementing the Regulation across the countries. Notably, the provided definition for pseudonymized data has been criticized because it leaves too much room for interpretations, and it might undermine the harmonization of the data protection across the countries. PMID- 29187735 TI - Mitochondrial genomes uncover the maternal history of the Pamir populations. AB - The Pamirs, among the world's highest mountains in Central Asia, are one of homelands with the most extreme high altitude for several ethnic groups. The settlement history of modern humans on the Pamirs remains still opaque. Herein, we have sequenced the mitochondrial DNA (mtDNA) genomes of 382 individuals belonging to eight populations from the Pamirs and the surrounding lowlands in Central Asia. We construct the Central Asian (including both highlanders and lowlanders) mtDNA haplogroup tree at the highest resolution. All the matrilineal components are assigned into the defined mtDNA haplogroups in East and West Eurasians. No basal lineages that directly emanate from the Eurasian founder macrohaplogroups M, N, and R are found. Our data support the origin of Central Asian being the result of East-West Eurasian admixture. The coalescence ages for more than 93% mtDNA lineages in Central Asians are dated after the last glacial maximum (LGM). The post-LGM and/or later dispersals/admixtures play dominant roles in shaping the maternal gene pool of Central Asians. More importantly, our analyses reveal the mtDNA heterogeneity in the Pamir highlanders, not only between the Turkic Kyrgyz and the Indo-European Tajik groups, but also among three highland Tajiks. No evidence supports positive selection or relaxation of selective constraints in the mtDNAs of highlanders as compared to that of lowlanders. Our results suggest a complex history for the peopling of Pamirs by multiple waves of migrations from various genetic resources during different time scales. PMID- 29187737 TI - The role of CNVs in the etiology of rare autosomal recessive disorders: the example of TRAPPC9-associated intellectual disability. AB - INTRODUCTION: A large number of genes involved in autosomal recessive forms of intellectual disability (ID) were identified over the past few years through whole-exome sequencing (WES) or whole-genome sequencing in consanguineous families. Disease-associated variants in TRAPPC9 were reported in eight multiplex consanguineous sibships from different ethnic backgrounds, and led to the delineation of the phenotype. Affected patients have microcephaly, obesity, normal motor development, severe ID, and language impairment and brain anomalies. PATIENTS: We report six new patients recruited through a national collaborative network. RESULTS: In the two patients heterozygous for a copy-number variation (CNV), the phenotype was clinically relevant with regard to the literature, which prompted to sequence the second allele, leading to identification of disease associated variants in both. The third patient was homozygote for an intragenic TRAPPC9 CNV. The phenotype of the patients reported was concordant with the literature. Recent reports emphasized the role of CNVs in the etiology of rare recessive disorders. CONCLUSION: This study demonstrates that CNVs significantly contribute to the mutational spectrum of TRAPPC9 gene, and also confirms the interest of combining WES with CNV analysis to provide a molecular diagnosis to patients with rare Mendelian disorders. PMID- 29187738 TI - Signaling mechanisms that regulate ex vivo survival of human acute myeloid leukemia initiating cells. PMID- 29187739 TI - Super-radiance reveals infinite-range dipole interactions through a nanofiber. AB - Atoms interact with each other through the electromagnetic field, creating collective states that can radiate faster or slower than a single atom, i.e., super- and sub-radiance. When the field is confined to one dimension it enables infinite-range atom-atom interactions. Here we present the first report of infinite-range interactions between macroscopically separated atomic dipoles mediated by an optical waveguide. We use cold 87Rb atoms in the vicinity of a single-mode optical nanofiber (ONF) that coherently exchange evanescently coupled photons through the ONF mode. In particular, we observe super-radiance of a few atoms separated by hundreds of resonant wavelengths. The same platform allows us to measure sub-radiance, a rarely observed effect, presenting a unique tool for quantum optics. This result constitutes a proof of principle for collective behavior of macroscopically delocalized atomic states, a crucial element for new proposals in quantum information and many-body physics. PMID- 29187740 TI - Observed positive vegetation-rainfall feedbacks in the Sahel dominated by a moisture recycling mechanism. AB - Classic, model-based theory of land-atmosphere interactions across the Sahel promote positive vegetation-rainfall feedbacks dominated by surface albedo mechanism. However, neither the proposed positive vegetation-rainfall feedback nor its underlying albedo mechanism has been convincingly demonstrated using observational data. Here, we present observational evidence for the region's proposed positive vegetation-rainfall feedback on the seasonal to interannual time scale, and find that it is associated with a moisture recycling mechanism, rather than the classic albedo-based mechanism. Positive anomalies of remotely sensed vegetation greenness across the Sahel during the late and post-monsoon periods favor enhanced evapotranspiration, precipitable water, convective activity and rainfall, indicative of amplified moisture recycling. The identified modest low-level cooling and anomalous atmospheric subsidence in response to positive vegetation greenness anomalies are counter to the responses expected through the classic vegetation-albedo feedback mechanism. The observational analysis further reveals enhanced dust emissions in response to diminished Sahel vegetation growth, potentially contributing to the positive vegetation-rainfall feedback.

AB - Myosin VI (MVI) has been found to be overexpressed in ovarian, breast and prostate cancers. Moreover, it has been shown to play a role in regulating cell proliferation and migration, and to interact with RNA Polymerase II (RNAPII). Here, we find that backfolding of MVI regulates its ability to bind DNA and that a putative transcription co-activator NDP52 relieves the auto-inhibition of MVI to enable DNA binding. Additionally, we show that the MVI-NDP52 complex binds RNAPII, which is critical for transcription, and that depletion of NDP52 or MVI reduces steady-state mRNA levels. Lastly, we demonstrate that MVI directly interacts with nuclear receptors to drive expression of target genes, thereby suggesting a link to cell proliferation and migration. Overall, we suggest MVI may function as an auxiliary motor to drive transcription. PMID- 29187743 TI - Synaptic transmission: Closer encounters. PMID- 29187744 TI - It is a marathon rather than a sprint: an initial exploration of unmet needs and support preferences of caregivers of children with SCI. AB - STUDY DESIGN: Focus group study. OBJECTIVES: Explore unmet needs and support preferences of caregivers of youth with spinal cord injury (SCI). SETTING: One pediatric specialty rehabilitation hospital system in the United States. METHODS: Four focus groups were conducted with a convenience sample of 26 caregivers who were primarily mothers (96%) and married (65%), and had at least some college education (85%). Children living with SCI were on average 12.8 years old (SD = 3.3, 8-18). The average age of injury was 4.7 years (SD = 4.4, 0-16.2); mean injury duration was 8.2 years (SD = 3.9, 2-16); 77% had paraplegia; and 58% were male. Focus groups were digitally recorded, transcribed verbatim, and coded using thematic analysis and NVivo. RESULTS: Qualitative data highlighted caregiver perspectives on unmet needs relating to two phases of care: acute and rehabilitation vs. current life with SCI, and two kinds of stressors: those associated with SCI and care vs. those related to other areas of the caregivers' lives, especially their families. Caregivers described stressful interactions with care systems and community services, articulated several concerns regarding well-being of family members, and noted that both they and their children with SCI experienced isolation. Caregivers articulated preferences for additional support from professionals and peers. CONCLUSIONS: Data suggest the need for ongoing caregiver interventions and strengthened family-centered care systems, including professional assistance navigating health systems and peer support. Intervention development would benefit from further qualitative data collection with additional caregivers of youth with SCI, including multiple family members, and families from more diverse care settings. PMID- 29187745 TI - A latent structural analysis of health behaviors among people living with spinal cord injury. AB - STUDY DESIGN: Cross-sectional study. OBJECTIVES: To develop a latent structural model of health behaviors among people with spinal cord injury (SCI) that accounts for measurement of underlying factors and their association with demographic and injury-related variables. SETTING: The data were collected at a large specialty hospital and analyzed at a medical university in the Southeastern United States. METHODS: A total of 1871 participants with traumatic SCI of at least 1-year duration were included. Exploratory factor analysis (EFA) was used to identify the latent health behavior structures. Several key exogenous variables were also linked with the latent health behavior factors. RESULTS: Five latent health behavior factors were identified by the EFA with excellent model fit (root mean square error of approximation = 0.043). These latent factors included (1) medication non-compliance, (2) prescription medication and substance use, (3) smoking, (4) alcohol consumption, and (5) healthy lifestyle activities and participation. Sex, race/ethnicity, age, years since injury, and injury severity were all significantly associated with at least one latent health behavior factor. For instance, men scored higher in smoking and alcohol consumption, whereas women scored higher in prescription medication and substance use. Non-whites scored higher on the medication non-compliance dimension and lower on the healthy lifestyle activities and participation dimension. CONCLUSIONS: Utilization of latent health behavior factors provides more stable and comprehensive composite scores than does a single observed health behavior indicator. There are important differences in behaviors based on individual characteristics.

PMID- 29187746 TI - Genome-wide haplotype-based association analysis of major depressive disorder in Generation Scotland and UK Biobank. AB - Genome-wide association studies using genotype data have had limited success in the identification of variants associated with major depressive disorder (MDD). Haplotype data provide an alternative method for detecting associations between variants in weak linkage disequilibrium with genotyped variants and a given trait of interest. A genome-wide haplotype association study for MDD was undertaken utilising a family-based population cohort, Generation Scotland: Scottish Family Health Study (n = 18,773), as a discovery cohort with UK Biobank used as a population-based replication cohort (n = 25,035). Fine mapping of haplotype boundaries was used to account for overlapping haplotypes potentially tagging the same causal variant. Within the discovery cohort, two haplotypes exceeded genome wide significance (P < 5 * 10-8) for an association with MDD. One of these haplotypes was nominally significant in the replication cohort (P < 0.05) and was located in 6q21, a region which has been previously associated with bipolar disorder, a psychiatric disorder that is phenotypically and genetically correlated with MDD. Several haplotypes with P < 10-7 in the discovery cohort were located within gene coding regions associated with diseases that are comorbid with MDD. Using such haplotypes to highlight regions for sequencing may lead to the identification of the underlying causal variants. PMID- 29187749 TI - Hyponatremia in patients receiving parenteral nutrition: the importance of correcting serum sodium for total proteins. The role of the composition of parenteral nutrition in the development of hyponatremia. AB - BACKGROUND/OBJECTIVES: Hyponatremia is the most common electrolyte disorder, and is associated with high-morbimortality rates. The true prevalence of hyponatremia in patients on parenteral nutrition (PN) is unknown, and the relationship between PN composition and development of hyponatremia has yet to be studied. Hypoproteinemia, a common finding in patients receiving PN, induces an overestimation of serum sodium (SNa) levels, when using indirect electrolyte methodology. Thus, SNa should be corrected for serum total protein levels (TP). The objective was to accurately determine the prevalence of hyponatremia (indirect SNa corrected for PT) and evaluate the relationship between the composition of PN and the development of hyponatremia. SUBJECTS/METHODS: Medical records of 222 hospitalized patients receiving total PN during a 7-month period were reviewed. Composition of PN, indirect SNa-mmol/l-, and SNa corrected for TP (SNa-TP)-mmol/l-, both upon initiation and during PN administration, were analyzed. RESULTS: Hyponatremia (SNa < 135 mmol/l) was present in 81% of subjects when SNa was corrected for TP, vs. 43% without correction (p = 0.001). In total 64% of patients that were eunatremic upon initiation of PN developed hyponatremia during PN administration, as detected by SNa-TP, vs. 28% as detected by uncorrected SNa (p < 0.001). There were no significant differences in volume, osmolarity, sodium or total osmols administered in PN between patients who developed hyponatremia and those who remained eunatremic. CONCLUSIONS: A majority of patients receiving PN present hyponatremia, when indirect SNa levels are corrected for TP. The development of hyponatremia during PN is not related to the composition of the PN. PMID- 29187750 TI - Beverage consumption in Australian children. AB - BACKGROUND/OBJECTIVES: While beverages are an important dietary source of water and some essential nutrients, consumption of sweet beverages has increasingly been linked to adverse health outcomes. Currently there is a paucity of longitudinal consumption data on beverage consumption in Australian children. SUBJECTS/METHODS: The Longitudinal Study of Australian Children has run biennially since 2004. Twenty four-hour recall data collected over 6 waves from the birth cohort (aged 0-1 year at baseline) was analysed and demographics were assessed for associations. RESULTS: Five thousand one hundred and seven children participated at baseline, with a 71-90% retention of participants at each wave. Water consumption remained consistent with age over time, with more than 90% consuming more than one glass in the last 24-h. Proportions of fruit juice consumers decreased overall. Soft drink and cordial consumer proportions increased from 1% (0-1 year), to 28% (2 years) and 43% (10 years). Between 2 and 10 years, proportions of consumption of full-cream milk decreased by 8% and for skim milk this proportion increased by 51%. High proportions of consumers of soft drink/cordial was significantly associated with older children, males, children with a medical condition, living in a rural area, low socio-economic status and Indigenous Australians. CONCLUSIONS: Water consumption remained consistently high across the ages, while fruit juice was commonly introduced into the diet early childhood. While proportions of fruit juice consumers decreased after the age of 2 years, proportions of soft drink consumers increased. The findings from this study should assist with surveillance data and inform policy and interventions aimed at reducing consumption of sweet beverages. PMID- 29187748 TI - Genome-wide association study of subcortical brain volume in PTSD cases and trauma-exposed controls. AB - Depending on the traumatic event, a significant fraction of trauma survivors subsequently develop PTSD. The additional variability in PTSD risk is expected to arise from genetic susceptibility. Unfortunately, several genome-wide association studies (GWAS) have failed to identify a consistent genetic marker for PTSD. The heritability of intermediate phenotypes such as regional brain volumes is often 80% or higher. We conducted a GWAS of subcortical brain volumes in a sample of recent military veteran trauma survivors (n = 157), grouped into PTSD (n = 66) and non-PTSD controls (n = 91). Covariates included PTSD diagnosis, sex, intracranial volume, ancestry, childhood trauma, SNP*PTSD diagnosis, and SNP*childhood trauma. We identified several genetic markers in high linkage disequilibrium (LD) with rs9373240 (p = 2.0 * 10-7, FDR q = 0.0375) that were associated with caudate volume. We also observed a significant interaction between rs9373240 and childhood trauma (p-values = 0.0007-0.002), whereby increased trauma exposure produced a stronger association between SNPs and increased caudate volume. We identified several SNPs in high LD with rs34043524, which is downstream of the TRAM1L1 gene that were associated with right lateral ventricular volume (p = 1.73 * 10-7; FDR q = 0.032) and were also associated with lifetime alcohol abuse or dependence (p = 2.49 * 10-7; FDR q = 0.0375). Finally, we identified several SNPs in high LD with rs13140180 (p = 2.58 * 10-7; FDR q = .0016), an intergenic region on chromosome 4, and several SNPs in the TMPRSS15 associated with right nucleus accumbens volume (p = 2.58 * 10-7; FDR q = 0.017). Both TRAM1L1 and TMPRSS15 have been previously implicated in neuronal function. Key results survived genome-wide multiple-testing correction in our sample. Leveraging neuroimaging phenotypes may offer a shortcut, relative to clinical phenotypes, in mapping the genetic architecture and neurobiological pathways of PTSD. PMID- 29187751 TI - Demonstration of chemistry at a point through restructuring and catalytic activation at anchored nanoparticles. AB - Metal nanoparticles prepared by exsolution at the surface of perovskite oxides have been recently shown to enable new dimensions in catalysis and energy conversion and storage technologies owing to their socketed, well-anchored structure. Here we show that contrary to general belief, exsolved particles do not necessarily re-dissolve back into the underlying perovskite upon oxidation. Instead, they may remain pinned to their initial locations, allowing one to subject them to further chemical transformations to alter their composition, structure and functionality dramatically, while preserving their initial spatial arrangement. We refer to this concept as chemistry at a point and illustrate it by tracking individual nanoparticles throughout various chemical transformations. We demonstrate its remarkable practical utility by preparing a nanostructured earth abundant metal catalyst which rivals platinum on a weight basis over hundreds of hours of operation. Our concept enables the design of compositionally diverse confined oxide particles with superior stability and catalytic reactivity. PMID- 29187752 TI - Inhibiting Rho kinase promotes goal-directed decision making and blocks habitual responding for cocaine. AB - The prelimbic prefrontal cortex is necessary for associating actions with their consequences, enabling goal-directed decision making. We find that the strength of action-outcome conditioning correlates with dendritic spine density in prelimbic cortex, suggesting that new action-outcome learning involves dendritic spine plasticity. To test this, we inhibited the cytoskeletal regulatory factor Rho kinase. We find that the inhibitor fasudil enhances action-outcome memory, resulting in goal-directed behavior in mice that would otherwise express stimulus response habits. Fasudil transiently reduces prelimbic cortical dendritic spine densities during a period of presumed memory consolidation, but only when paired with new learning. Fasudil also blocks habitual responding for cocaine, an effect that persists over time, across multiple contexts, and depends on actin polymerization. We suggest that Rho kinase inhibition promotes goal-oriented action selection by augmenting the plasticity of prelimbic cortical dendritic spines during the formation of new action-outcome memories. PMID- 29187753 TI - Subchronic olanzapine exposure leads to increased expression of myelination related genes in rat fronto-medial cortex. AB - Schizophrenia is a psychotic disorder with severe and disabling symptoms, such as hallucinations, delusions, blunted affect and social withdrawal. The neuropathology remains elusive, but disturbances in immunity-related processes, neuronal connectivity and myelination have consistently been linked to schizophrenia. Antipsychotic drugs can be efficient in reducing symptoms, acting primarily on the dopamine system, but additional biological targets are likely to exist. Here we have screened for novel mechanisms of action in an animal model, using adult rats exposed to long-acting olanzapine, achieving stable and clinically relevant antipsychotic drug concentrations. By microarray-based examination of global gene expression in the fronto-medial cortex, at the single gene- and gene-set level, we observed downregulation of two neuropeptide-encoding genes, Vgf and Cort (fold change -1,25 and -1,48, respectively) in response to olanzapine exposure. Furthermore, we demonstrated significant upregulation of five out of ~2000 GO predefined gene sets after olanzapine exposure. Strikingly, all were linked to myelination and oligodendrocyte development; "Ensheathment of neurons", "Axon ensheathment", "Myelination", "Myelin sheath" and "Oligodendrocyte development" (FDR-values < 25). Sixteen of the leading edge genes in these gene sets were analysed independently by qPCR, of which 11 genes displayed significant upregulation, including Plp1, Mal, Mag and Cnp (fold change: 1,30, 1,50, 1,30 and 1,15, respectively). Several of the upregulated genes (e.g. MAG, MAL and CNP) have previously been reported as downregulated in post-mortem brain samples from schizophrenia patients. Although caution needs to be taken when extrapolating results from animal studies to humans, the data suggest a role for olanzapine in alleviating myelination-related dysfunction in schizophrenia. PMID- 29187754 TI - Fluoxetine treatment is effective in a rat model of childhood-induced post traumatic stress disorder. AB - Although selective serotonin reuptake inhibitors (SSRIs) are first-line treatment for post-traumatic stress disorder (PTSD) patients, their therapeutic efficacy is limited. Childhood adversities are considered a risk factor for developing PTSD in adulthood but may trigger PTSD without additional trauma in some individuals. Nevertheless, just as childhood is considered a vulnerable period it may also be an effective period for preventive treatment. Using a rat model of childhood induced PTSD, pre-pubertal stress (juvenile stress, JVS), we compared the therapeutic effects of fluoxetine and examined the effectiveness of 1 month of fluoxetine treatment following JVS and into adulthood compared to treatment in adulthood. Since not all individuals develop PTSD following a trauma, comparing only group means is not the adequate type of analysis. We employed a behavioral profiling approach, which analyzes individual differences compared to the normal behavior of a control group. Animals exposed to JVS exhibited a higher proportion of affected animals as measured using the elevated plus maze 8 weeks after JVS. Fluoxetine treatment following the JVS significantly decreased the proportion of affected animals as measured in adulthood. Fluoxetine treatment in adulthood was not effective. The results support the notion that childhood is not only a vulnerable period but also an effective period for preventive treatment.

We designed a pilot study on microvascular anastomoses with the aim of verifying if a short course, easily reproducible, could transmit microvascular skills to participants; if the chosen pre-test was predictive of final performance; and if age could influence the outcome. A total of 30 participants (10 students, 10 residents and 10 surgeons) without any previous microvascular experience were instructed and tested during a single 3 to 5 hour course. The two microanastomoses evaluated were the first ever performed by each participant. More than the half of the cohort was able to produce both patent microanastomoses in less than 2 hours; two-thirds of the attempted microanastomoses were patent. The pretest predicted decent scores from poor performances with a sensitivity of 61.5%, specificity of 100%, positive predictive value of 100% and negative predictive value of 40%. Students and residents obtained significantly higher scores than surgeons. Since our course model is short, cost-effective and highly reproducible, it could be introduced and implemented anywhere as an educational prospect for preselecting young residents showing talent and natural predisposition and having ambitions towards microvascular reconstructive surgery.

AB - 1q21.1 hemizygous microdeletion is a copy number variant leading to eightfold increased risk of schizophrenia. In order to investigate biological alterations induced by this microdeletion, we generated a novel mouse model (Df(h1q21)/+) and characterized it in a broad test battery focusing on schizophrenia-related assays. Df(h1q21)/+ mice displayed increased hyperactivity in response to amphetamine challenge and increased sensitivity to the disruptive effects of amphetamine and phencyclidine hydrochloride (PCP) on prepulse inhibition. Probing of the direct dopamine (DA) pathway using the DA D1 receptor agonist SKF-81297 revealed no differences in induced locomotor activity compared to wild-type mice, but Df(h1q21)/+ mice showed increased sensitivity to the DA D2 receptor agonist quinpirole and the D1/D2 agonist apomorphine. Electrophysiological characterization of DA neuron firing in the ventral tegmental area revealed more spontaneously active DA neurons and increased firing variability in Df(h1q21)/+ mice, and decreased feedback reduction of DA neuron firing in response to amphetamine. In a range of other assays, Df(h1q21)/+ mice showed no difference from wild-type mice: gross brain morphology and basic functions such as reflexes, ASR, thermal pain sensitivity, and motor performance were unaltered. Similarly, anxiety related measures, baseline prepulse inhibition, and seizure threshold were unaltered. In addition to the central nervous system-related phenotypes, Df(h1q21)/+ mice exhibited reduced head-to tail length, which is reminiscent of the short stature reported in humans with 1q21.1 deletion. With aspects of both construct and face validity, the Df(h1q21)/+ model may be used to gain insight into schizophrenia-relevant alterations in dopaminergic transmission.

AB - The most frequent sequelae following a translabyrinthine approach for vestibular schwannoma resection is complete hearing loss on the affected side. Such patients could benefit from a cochlear implant, provided that two essential requisites are met before surgery: a preserved cochlear nerve and a patent cochlea to accommodate the electrode array. The goal of our study is to determine the prevalence and extent of cochlear ossification following a translabyrinthine approach. Postoperative MRI of 41 patients were retrospectively reviewed. Patients were classified according to the degree of cochlear obliteration into three groups (patent cochlea, partially obliterated cochlea and totally obliterated cochlea). The interval between surgery and the first MRI was studied as well as its relationship with the rate of cochlear ossification. At first postoperative MRI (mean interval of 20 months), 78% of patients showed some degree of cochlear ossification. Differences were found in the time interval between surgery and first MRI for each group, showing a smaller interval of time the patent cochlea group (p > 0.05). When MRI was performed before the first year after surgery, a larger rate of patent cochlea was found (p > 0.05). The present study suggests that cochlear ossification is a time-depending process, whose grounds are still to be defined. PMID- 29187760 TI - The EXIT (ex-utero intrapartum treatment) procedure - from the paediatric ENT perspective. AB - The main principle of the EXIT procedure is to maintain uteroplacental circulation with neonatal anaesthesia by controlled uterine hypotonia. This enables securing the foetal airways and decompress or resect large neck and mediastinal foetal masses. The authors present their experience with use of the EXIT procedure in 7 foetuses in whom evaluation and management of the airways were performed. In 4 patients, the neck mass was surgically removed in the neonatal period, in 1 the propranolol treatment was introduced. Two newborns died shortly after the EXIT procedure. The EXIT procedure allows the paediatric otolaryngologist to provide airway patency of newborns during delivery. Both ultrasound and MR imaging are crucial in the prenatal assessment of foetal head and neck masses. Their application in the evaluation of any foetal anomaly is essential for proper prognosis and treatment. Maternal monitoring for complications such as polyhydramnios and preterm labour are important in planning and desirability of the EXIT procedure. PMID- 29187761 TI - Gold nanocage-based lateral flow immunoassay for immunoglobulin G. AB - The authors describe a gold nanocage-based lateral flow strip biosensor (LFSB) for low-cost and sensitive detection of IgG. This protein was used as a model analyte to demonstrate the proof-of-concept. The method combines the unique optical properties of gold nanocages (GNCs) with highly efficient chromatographic separation. A sandwich-type of immunoreactions occurs on the GNC-based LFSB which has the attractive features of avoiding multiple incubation, separation, and washing steps. The captured GNCs on the purple test zone and control zone of the biosensor are producing characteristic purple bands, and this enables IgG even to be visually detected. Quantitatation was accomplished by reading the intensities of the bands with a portable strip reader. The LFSB fabrication and assay parameters were optimized. The biosensor displays a linear response in the 0.5 to 50 ng.mL-1 IgG concentration range, and it has a 15 min assay time. The detection limit is 0.1 ng.mL-1 of IgG, which is 2.5 times lower than that when using a gold nanoparticle-based LFSB. In our perception, this assay has a wide potential for the detection of other proteins and species for which respective antibodies are available.

AB - Abstract: A relation between oil uptake and cancer as well as induction of hepatic inflammation was shown earlier. It is discussed that the main oil oxidation products-hydroperoxides and carbonyls-might be the reason for the mentioned diseases. In this manuscript quantitative determination of aldehydes which are formed during oxidation of triolein-as a model substance-using the Rancimat 679 is described. The oxidation of 11 g of triolein is carried out at 120 degrees C sparging air with a flow of 20 dm3/h for 10 h. A series of aliphatic aldehydes starting from hexanal to decanal as well as decenal was identified by LC-MS/MS and quantified as DNPH derivatives. In addition, the total amount of carbonyls was determined. Based on the calibration with hexanal, all other dominant substances were in the similar concentration range with maximum concentrations of 1.6 umol/cm3 of hexanal, 2.3 umol/cm3 of heptanal, 2.5 umol/cm3 of octanal, 3.2 umol/cm3 of nonanal, 4.0 umol/cm3 of decanal after 6 h. The total amount of carbonyls reached a maximum after 6 h being 27 umol/cm3 for triolein without antioxidant. The results of this investigation will be a basis for further toxicological studies on oxidized oils.

AB - The longitudinal Three City Study of low-income families with children measures food hardships using fewer questions and some different questions from the standard U.S. instrument for measuring food security, the Household Food Security Survey Module (HFSSM) in the Current Population Survey (CPS). We utilize a Rasch measurement model to identify thresholds of very low food security among households and very low food security among children in the Three City Study that are comparable to thresholds from the HFSSM. We also use the Three City Study to empirically investigate the determinants of food insecurity and of these specific food insecurity outcomes, estimating a multivariate behavioral Rasch model that is adapted to address longitudinal data. The estimation results indicate that participation in the Supplemental Nutrition Assistance Program and the Temporary Assistance for Needy Families program reduce food insecurity, while poverty and disability among caregivers increase it. Besides its longitudinal structure, the Three City Study measures many more characteristics about households than the CPS. Our estimates reveal that financial assistance through social networks and a household's own financial assets reduce food insecurity, while its outstanding loans increase insecurity. PMID- 29187763 TI - Race, Marital History, and Risks for Stroke in US Older Adults. AB - Stroke is among the leading causes of disability and death in the United States, and racial differences are greater for stroke than for all other major chronic diseases. Considering the equally sizeable racial disparities in marital life and associated risks across adulthood, the current study hypothesizes that black white differences in marital history play an important role in the large racial inequalities in the incidence of stroke. The major objective are to (i) demonstrate how marital history is associated with the incidence of stroke, (ii) examine how marital factors mediate and/or moderate racial disparities in stroke, and (iii) examine the factors that may explain the associations. Using retrospective and prospective data from the Health and Retirement Study (n = 23,289), the results show that non-Hispanic (NH) blacks have significantly higher rates of marital instability, greater numbers of health-risk factors, and substantially higher rates of stroke compared with NH whites. Contrary to the cumulative disadvantage hypothesis, findings from discrete-time-hazard models show that the effects of marital history are more pronounced for NH whites than for NH blacks. Risks for stroke were significantly higher in NH whites who were currently divorced, remarried, and widowed, as well as in those with a history of divorce or widowhood, compared with NH whites who were continuously married. In NH blacks, risks for stroke were elevated only in those who had either never married or had been widowed-with no significant risks attributable to divorce. The potential mechanisms underlying the associations are assessed, and the implications of the findings are discussed. PMID- 29187765 TI - Effect of Land Use, Seasonality, and Hydrometeorological Conditions on the K+ Concentration-Discharge Relationship During Different Types of Floods in Carpathian Foothills Catchments (Poland). AB - The purpose of the study was to determine the role of land use, seasonality, and hydrometeorological conditions on the relationship between stream water potassium (K+) concentration and discharge during different types of floods-short- and long duration rainfall floods as well as snowmelt floods on frozen and thawed soils. The research was conducted in small catchments (agricultural, woodland, mixed use) in the Carpathian Foothills (Poland). In the woodland catchment, lower K+ concentrations were noted for each given specific runoff value for summer rainfall floods versus snowmelt floods (seasonal effect). In the agricultural and mixed-use catchments, the opposite was true due to their greater ability to flush K+ out of the soil in the summer. In the stream draining woodland catchment, higher K+ concentrations occurred during the rising limb than during the falling limb of the hydrograph (clockwise hysteresis) for all flood types, except for snowmelt floods with the ground not frozen. In the agricultural catchment, clockwise hystereses were produced for short- and long-duration rainfall floods caused by high-intensity, high-volume rainfall, while anticlockwise hystereses were produced for short- and long-duration rainfall floods caused by low intensity, low-volume rainfall as well as during snowmelt floods with the soil frozen and not frozen. In the mixed-use catchment, the hysteresis direction was also affected by different lag times for water reaching stream channels from areas with different land use. K+ hystereses for the woodland catchment were more narrow than those for the agricultural and mixed-use catchments due to a smaller pool of K+ in the woodland catchment. In all streams, the widest hystereses were produced for rainfall floods preceded by a long period without rainfall. PMID- 29187766 TI - Perceptions and Experiences of an Attachment-Based Intervention for Parents Troubled by Intimate Partner Violence. AB - It is known that intimate partner violence (IPV) negatively affects both parental capacity and children's well-being, but few studies have focused on the experiences of those taking part in family interventions focused on IPV. In this study, 26 parents (16 mothers and 10 fathers) with a history of IPV participated in focus groups concerning their attachment-based group intervention experience in the program Parenting and Violence. The transcripts, subjected to thematic analysis, showed that participants experienced the intervention as supportive and confirming of their role as parents. Parents described feeling more in control, more self-confident, more skilled in communicating, and more able to provide security for their children. However, they also expressed a need for continuing support to maintain their improved parenting strategies. PMID- 29187767 TI - Triads in Equine-Assisted Social Work Enhance Therapeutic Relationships with Self Harming Adolescents. AB - Despite an increasing number of studies, there is still a lack of knowledge about the unique features that underlie the process in equine assisted social work (EASW). This study aimed to reveal, through qualitative methods, the dyads within the triad that become stronger during the process of EASW, as well as the effect of the participation of the horse on the relationship between the counselor and client. Data were collected through in-depth interviews with nine female self harming clients aged 15-21 years and eight staff members. The interviews, together with video-recorded human-horse interactions with three staff members and four clients were analyzed, resulting in additional issues answered by these three staff members and four clients in a second interview. Critical dialogues between patterns and fragmentations in the narratives and video-recordings, as well as a dialogue with the participants while they were viewing videos of their own EASW sessions, led to the conclusion that adding a horse qualitatively changes therapeutic relationships in EASW. The different triads consist of different liaisons between actors in the triad, giving rise to unique combinations. The quality of the relationships depends on both the staff and the clients' attachment orientations. Further research is needed to investigate how the degree of emotional connection to the horse affects the impact that horses have on triads in EASW. PMID- 29187768 TI - Barium and Radium Complexation with Ethylenediaminetetraacetic Acid in Aqueous Alkaline Sodium Chloride Media. AB - The speciation of Ra2+ and Ba2+ with EDTA was investigated at 25 degrees C in aqueous alkaline NaCl media as a function of ionic strength (0.2-2.5 mol.L-1) in two pH regions where the EDTA4- and HEDTA3- species dominate. The stability constants for the formation of the [BaEDTA]2- and [RaEDTA]2- complexes were determined using an ion exchange method. Barium-133 and radium-226 were used as radiotracers and their concentrations in the aqueous phase were measured using liquid scintillation counting and gamma spectrometry, respectively. The specific ion interaction theory (SIT) was used to account for [NaEDTA]3- and [NaHEDTA]2- complex formation, and used to extrapolate the logarithms of the apparent stability constants (log10K) to zero ionic strength (BaEDTA2-: 9.86 +/- 0.09; RaEDTA2-: 9.13 +/- 0.07) and obtain the Ba2+ and Ra2+ ion interaction parameters: [epsilon(Na+, BaEDTA2-) = - (0.03 +/- 0.11); epsilon(Na+, RaEDTA2-) = - (0.10 +/- 0.11)]. It was found that in the pH region where HEDTA3- dominates, the reaction of Ba2+ or Ra2+ with the HEDTA3- ligand also results in the formation of the BaEDTA2- and RaEDTA2- complexes (as it does in the region where the EDTA4- ligand dominates) with the release of a proton. Comparison of the ion interaction parameters of Ba2+ and Ra2+ strongly indicates that both metal ions and their EDTA complexes have similar activity coefficients and undergo similar short-range interactions in aqueous NaCl media.

PMID- 29187770 TI - Classification of micro-CT images using 3D characterization of bone canal patterns in human osteogenesis imperfecta. AB - Few studies have analyzed the microstructural properties of bone in cases of Osteogenenis Imperfecta (OI), or 'brittle bone disease'. Current approaches mainly focus on bone mineral density measurements as an indirect indicator of bone strength and quality. It has been shown that bone strength would depend not only on composition but also structural organization. This study aims to characterize 3D structure of the cortical bone in high-resolution micro CT images. A total of 40 bone fragments from 28 subjects (13 with OI and 15 healthy controls) were imaged using micro tomography using a synchrotron light source (SRMUCT). Minkowski functionals - volume, surface, curvature, and Euler characteristics - describing the topological organization of the bone were computed from the images. The features were used in a machine learning task to classify between healthy and OI bone. The best classification performance (mean AUC - 0.96) was achieved with a combined 4-dimensional feature of all Minkowski functionals. Individually, the best feature performance was seen using curvature (mean AUC - 0.85), which characterizes the edges within a binary object. These results show that quantitative analysis of cortical bone microstructure, in a computer-aided diagnostics framework, can be used to distinguish between healthy and OI bone with high accuracy. PMID- 29187771 TI - Who are Your Joneses? Socio-Specific Income Inequality and Trust. AB - Trust is a good approach to explain the functioning of markets, institutions or society as a whole. It is a key element in almost every commercial transaction over time and might be one of the main explanations of economic success and development. Trust diminishes the more we perceive others to have economically different living realities. In most of the relevant contributions, scholars have taken a macro perspective on the inequality-trust linkage, with an aggregation of both trust and inequality on a country level. However, patterns of within-country inequality and possibly influential determinants, such as perception and socioeconomic reference, remained undetected. This paper offers the opportunity to look at the interplay between inequality and trust at a more refined level. A measure of (generalized) trust emerges from ESS 5 survey which asks "...generally speaking, would you say that most people can be trusted, or that you can't be too careful in dealing with people?". With the use of 2009 EU-SILC data, measurements of income inequality are developed for age-specific groups of society in 22 countries. A sizable variation in inequality measures can be noticed. Even in low inequality countries, like Sweden, income imbalances within certain age groups have the potential to undermine social trust. PMID- 29187772 TI - Fearful Faces do Not Lead to Faster Attentional Deployment in Individuals with Elevated Psychopathic Traits. AB - In the current study, a gaze-cueing experiment (similar to Dawel et al. 2015) was conducted in which the predictivity of a gaze-cue was manipulated (non-predictive vs highly predictive). This was done to assess the degree to which individuals with elevated psychopathic traits can use contextual information (i.e., the predictivity of the cue). Psychopathic traits were measured with the Self-Report Psychopathy Scale-Short Form (SRP-SF) in a mixed sample (undergraduate students and community members). Results showed no group difference in reaction times between high and non-predictive cueing blocks, suggesting that individuals with elevated psychopathic traits can indeed use contextual information when it is relevant. In addition, we observed that fearful facial expressions did not lead to a change in reaction times in individuals with elevated psychopathic traits, whereas individuals with low psychopathic traits showed speeded responses when confronted with a fearful face, compared to a neutral face. This suggests that fearful faces do not lead to faster attentional deployment in individuals with elevated psychopathic traits. PMID- 29187773 TI - Phase Behavior of Poly(3-hexylthiophene-2,5-diyl). AB - The phase behavior of many conjugated polymers is rich with both crystalline and liquid crystalline phases. Recent computational efforts have identified the isotropic-to-nematic transition temperature for polymers such as poly(3 hexylthiophene-2,5-diyl) (P3HT). Herein, model predictions are combined with experimentally determined values of the equilibrium melting temperature as a function of chain length to provide the complete phase behavior for P3HT. Additionally, because a full description of the phase behavior requires proper accounting for the regioregularity of the chain, a thermodynamic relationship is derived to predict this behavior as a function of both chain length and regioregularity and the impact of regioregularity on the expected phase diagram is discussed. PMID- 29187774 TI - Effect of Superficial Gas Velocity on the Solid Temperature Distribution in Gas Fluidized Beds with Heat Production. AB - The hydrodynamics and heat transfer of cylindrical gas-solid fluidized beds for polyolefin production was investigated with the two-fluid model (TFM) based on the kinetic theory of granular flow (KTGF). It was found that the fluidized bed becomes more isothermal with increasing superficial gas velocity. This is mainly due to the increase of solids circulation and improvement in gas solid contact. It was also found that the average Nusselt number weakly depends on the gas velocity. The TFM results were qualitatively compared with simulation results of computational fluid dynamics combined with the discrete element model (CFD-DEM). The TFM results were in very good agreement with the CFD-DEM outcomes, so the TFM can be a reliable source for further investigations of fluidized beds especially large lab-scale reactors.

AB - This article is a discursive examination of children's status as knowledgeable moral agents within the Swedish child welfare system and in the widely used assessment framework BBIC. Departing from Fricker's concept of epistemic injustice, three discursive positions of children's moral status are identified: amoral, im/moral and dis/loyal. The findings show the undoubtedly moral child as largely missing and children's agency as diminished, deviant or rendered ambiguous. Epistemic injustice applies particularly to disadvantaged children with difficult experiences who run the risk of being othered, or positioned as reproducing or accommodating to the very same social problems they may be victimised by.

A created MATLAB function for the new fractional-order no-equilibrium system is also presented.

AB - Objective: The aim of this study was to evaluate our long-term results with the Zweymuller hochgezogen and SL total hip arthroplasty system. This is the first study to provide a 30-year follow-up. Methods: We reviewed 186 Alloclassic stem systems (Zweymuller hochgezogen (112) and SL (74), implanted in 179 patients from 1986 to 1987.Two different types of cementless acetabular components were used.143 patients had died over the last 30 years, so thirty out of 36 patients being still alive, with a mean follow-up of 29,48 years (SD 0,51), were contacted by telephone and evaluated radiologically and clinically. Our loss-to-follow up was 16,7%. The mean age at follow-up was 83,57 years (72,4-95,2; SD 6,77). Results: If the endpoint is defined as the removal of the stem for aseptic loosening (3 cases), the overall survival rate is 98,38%. If the endpoint is revision for any reason (27 cases), the survival rate is 85,48%. Eleven patients needed an exchange of head and liner. The mean time from implantation until change of head and liner was 21,44 years (SD 5,92).Most of the radiolucent lines and osteolytic zones were found in the proximal Gruen-zones 1 and 7 (69,7 and 21,2%). Conclusion: After 30 years of monitoring we can state that the evaluated system is very reliable in primary and secondary THA. PMID- 29187779 TI - Shared Authentic Leadership in Research Teams: Testing a Multiple Mediation Model. AB - Research teams face complex leadership and coordination challenges. We propose shared authentic leadership (SAL) as a timely approach to addressing these challenges. Drawing from authentic and functional leadership theories, we posit a multiple mediation model that suggests three mechanisms whereby SAL influences team effectiveness: shared mental models (SMM), team trust, and team coordination. To test our hypotheses, we collected survey data on leadership and teamwork within 142 research teams that recently published an article in a peer reviewed management journal. The results indicate team coordination represents the primary mediating mechanism accounting for the relationship between SAL and research team effectiveness. While teams with high trust and SMM felt more successful and were more satisfied, they were less successful in publishing in high-impact journals. We also found the four SAL dimensions (i.e., self awareness, relational transparency, balanced processing, and internalized moral perspective) to associate differently with team effectiveness. PMID- 29187780 TI - The Skull of Epidolops ameghinoi from the Early Eocene Itaborai Fauna, Southeastern Brazil, and the Affinities of the Extinct Marsupialiform Order Polydolopimorphia. AB - The skull of the polydolopimorphian marsupialiform Epidolops ameghinoi is described in detail for the first time, based on a single well-preserved cranium and associated left and right dentaries plus additional craniodental fragments, all from the early Eocene (53-50 million year old) Itaborai fauna in southeastern Brazil. Notable craniodental features of E. ameghinoi include absence of a masseteric process, very small maxillopalatine fenestrae, a prominent pterygoid fossa enclosed laterally by a prominent ectopterygoid crest, an absent or tiny transverse canal foramen, a simple, planar glenoid fossa, and a postglenoid foramen that is immediately posterior to the postglenoid process. Most strikingly, the floor of the hypotympanic sinus was apparently unossified, a feature found in several stem marsupials but absent in all known crown marsupials. "Type II" marsupialiform petrosals previously described from Itaborai plausibly belong to E. ameghinoi; in published phylogenetic analyses, these petrosals fell outside (crown-clade) Marsupialia. "IMG VII" tarsals previously referred to E. ameghinoi do not share obvious synapomorphies with any crown marsupial clade, nor do they resemble those of the only other putative polydolopimorphians represented by tarsal remains, namely the argyrolagids. Most studies have placed Polydolopimorphia within Marsupialia, related to either Paucituberculata, or to Microbiotheria and Diprotodontia. However, diprotodonty almost certainly evolved independently in polydolopimorphians, paucituberculatans and diprotodontians, and Epidolops does not share obvious synapomorphies with any marsupial order. Epidolops is dentally specialized, but several morphological features appear to be more plesiomorphic than any crown marsupial. It seems likely Epidolops that falls outside Marsupialia, as do morphologically similar forms such as Bonapartherium and polydolopids. Argyrolagids differ markedly in their known morphology from Epidolops but share some potential apomorphies with paucituberculatans. It is proposed that Polydolopimorphia as currently recognised is polyphyletic, and that argyrolagids (and possibly other taxa currently included in Argyrolagoidea, such as groeberiids and patagoniids) are members of Paucituberculata. This hypothesis is supported by Bayesian non-clock phylogenetic analyses of a total evidence matrix comprising DNA sequence data from five nuclear protein-coding genes, indels, retroposon insertions, and morphological characters: Epidolops falls outside Marsupialia, whereas argyrolagids form a clade with the paucituberculatans Caenolestes and Palaeothentes, regardless of whether the Type II petrosals and IMG VII tarsals are used to score characters for Epidolops or not. There is no clear evidence for the presence of crown marsupials at Itaborai, and it is possible that the origin and early evolution of Marsupialia was restricted to the "Austral Kingdom" (southern South America, Antarctica, and Australia).

AB - We consider the problem of exact sparse signal recovery from a combination of linear and magnitude-only (phaseless) measurements. A k-sparse signal x ? C n is measured as r = Bx and y = |Cx|, where B ? C m1*n and C ? C m2*n are measurement matrices and | . | is the element-wise absolute value. We show that if max(2m1, 1) + m2 >= 4k - 1, then a set of generic measurements are sufficient to recover every k-sparse x exactly, establishing the trade-off between the number of linear and magnitude-only measurements.

AB - Background: Coinfection with active tuberculosis (TB) is one of the leading causes of death in people living with HIV (PLWH) in Africa. This investigation explores the role of micronutrient supplementation in preventing active TB in PLWH. Methods: A randomized trial of nutritional supplementation was conducted among antiretroviral- naive (without previous antiretroviral treatment [ART]) HIV infected people in Botswana between 2004 and 2009. The study had a factorial design with four arms: the selenium (Se) alone arm, the multivitamins (MVT) alone arm that contained vitamin B complex and vitamins C and E, the combined Se+MVT group and the placebo group. Those participants with prior or current active TB were excluded, as were participants with advanced HIV disease (CD4 <250 cells/MUL) or who had already qualified for ART. HIV-positive adults (N=878) were followed monthly for study pill dispensation, every 3 months for CD4 cell count and every 6 months for viral load during 24 months or until they were started on ART. Results: The participants' characteristics were not significantly different among the four groups at baseline. Supplementation with Se alone (hazard ratio =0.20, 95% confidence interval: 0.04, 0.95, P=0.043) and the two combined SE groups (Se and Se+MVT) had significantly lower risk of developing incident TB disease compared with placebo in multivariate adjusted models (hazard ratio=0.32, 95% confidence interval: 0.11, 0.93, P=0.036). Multivitamins alone did not affect the incidence of TB. Isoniazid preventive therapy was received by 12.2% of participants, a rate that was not significantly different among the four study arms (P=0.122) and the newly diagnosed cases. Conclusion: Se supplementation, alone and with MVT, decreased the incidence of TB disease in PLWH who were ART naive. Supplementation with these micronutrients should be considered in HIV infection, prior to ART, in areas where TB and malnutrition are endemic.

DNA sequence data of mitochondrial cytochrome oxidase subunit I (COI) was generated from Scandinavian specimens of S. populnea populnea and specimens representing S. populnea lapponicassp. n. The two subspecies were not reciprocally monophyletic and genetic distances in COI were small. All synonyms of S. populnea populnea have been considered, and species similar to S. populnea populnea have been examined, and not found to be related to S. populnea lapponicassp. n. A male lectotype has been designated for each of the two following synonyms: Cerambyx decempunctatus De Geer, 1775, and Saperda salicis Zetterstedt, 1818. The synonymised species from Asia, S. balsamifera (Motshulsky, 1860), is elevated to subspecies: S. populnea balsamiferastat. n. We end with a discussion on the definition of subspecies under the unified species concept. PMID- 29187782 TI - Death by a thousand cuts: The health implications of black respectability politics. AB - The authors introduce the concept of "vigilance," capturing behaviors that reflect attempts to navigate racialized social spaces on a daily basis. Specifically, vigilant behaviors include care about appearance and language to be treated with respect, avoidance of social spaces, and psychological preparation for potential prejudice and discrimination. Furthermore, these behaviors align with those discussed in Black respectability politics debates. Using data from a population-representative sample of Black adults in Chicago, they report that vigilance is associated with poor physical and mental health indexed through chronic health conditions, depressive symptoms, and self-rated health. PMID- 29187785 TI - Revision of Eucorydia Hebard, 1929 from China, with notes on the genus and species worldwide (Blattodea, Corydioidea, Corydiidae). AB - The cockroach genus Eucorydia from China is revised. Five new species are described and illustrated: Eucorydia linglongsp. n., Eucorydia pilosasp. n., Eucorydia splendidasp. n., Eucorydia guilinensissp. n., and Eucorydia tangisp. n.. Corydia purpuralis Kirby, 1903 and Eucorydia paucipilosa Woo, Guo & Feng, 1986 are confirmed to be junior synonyms of Eucorydia dasytoides (Walker, 1868). Eucorydia hilaris (Kirby, 1903) is newly recorded from China. This genus and currently known species from around the world are discussed. The status of Eucorydia maxwelli (Hanitsch, 1915) is revived. Corydia plagiata Walker, 1868 is confirmed to be a junior synonym of Eucorydia ornata (Saussure, 1864). A checklist, key, and photographs of members of this genus are provided. PMID- 29187786 TI - Three new cavernicolous species of the millipede genus Trichopeltis Pocock, 1894 from southern China (Diplopoda, Polydesmida, Cryptodesmidae). AB - Three new species of Trichopeltis are described from caves in southern China: T. bellussp. n., T. intricatussp. n., and T. reflexussp. n., all presumed troglobites. The former two come from Yunnan Province, the latter one from Hunan Province. An updated key to all eleven currently known species of Trichopeltis is provided. PMID- 29187787 TI - Ancient diversity of Afrotropical Microborus: three endemic species - not one widespread. AB - The primarily Neotropical genus Microborus Blandford is represented with three species in Africa and Madagascar. The previously recorded species from this region, M. boops Blandford, is a Neotropical species restricted to Central America and is likely not found in the Afrotropics. The previously recognised species in western parts of Africa is M. camerunus (Eggers) and is resurrected from synonymy under M. boops. Molecular and morphological data revealed a second species of this complex in Madagascar, M. brevisetosus Jordal. Another new species, M. angustus Jordal, co-occurs with M. camerunus in Cameroon. Substantial genetic divergence indicate that Microborus was established in the Afrotropical region long before human transport across oceans. A key to Afrotropical species is provided. PMID- 29187788 TI - Scolytinae in hazelnut orchards of Turkey: clarification of species and identification key (Coleoptera, Curculionidae). AB - Hazelnut, a very important cash crop in Turkey, is frequently colonized by bark and ambrosia beetle species (Scolytinae). Some scolytine species may cause economic damage while other species do not; therefore, proper identification is important in orchard management. Extensive sampling demonstrated that the most common pest species in Turkey's hazelnut orchards are Anisandrus dispar, Xylosandrus germanus, and Xyleborinus saxesenii. Hypothenemus eruditus can also be common, but only colonizes branches that are already dead. Lymantor coryli, Hypoborus ficus, Taphrorychus ramicola, and Taphrorychus hirtellus are rare and do not causes damage to live plants. Xyleborinus saxesenii appears to have been frequently misidentified and misreported as either L. coryli or Xyleborus xylographus. The former is rare, and the latter probably does not occur in Turkey. To avoid future misidentifications, a dichotomous identification key is provided for bark and ambrosia beetles of hazelnut orchards in Turkey. PMID- 29187789 TI - Phylogenetic study of the genus Sternolophus Solier (Coleoptera, Hydrophilidae) based on adult morphology. AB - The phylogeny of the hydrophilid genus Sternolophus Solier, 1834 was examined in this study using 60 morphological adult characters, eight of them continuous and 52 discrete. The cladistic analysis resulted in a single most parsimonious tree with two major subclades corresponding, respectively, to species previously assigned to the subgenera Sternolophus s. str. Solier and Neosternolophus Zaitzev, although they are not re-instated. The species groups S. angolensis (Erichson, 1843) and S. solieri Castelnau, 1840 are recovered as monophyletic. The biogeography and diversification of the species of Sternolophus are briefly discussed. PMID- 29187790 TI - Seahorses of the Hippocampus coronatus complex: taxonomic revision, and description of Hippocampus haema, a new species from Korea and Japan (Teleostei, Syngnathidae). AB - Morphological and molecular analyses were conducted on 182 specimens belonging to the Hippocampus coronatus complex (H. coronatus sensu lato), collected in Korea and Japan 1933-2015, in order to clarify the taxonomic status of the species within this complex. Three species are recognized based on the shape of the coronet, the number of trunk rings (TrR) and tail rings (TaR), and presence or absence of a wing-tip spine (WS) at the dorsal fin base. Hippocampus coronatus Temminck & Schlegel, 1850 (H. coronatus sensu stricto), is diagnosed by 10 TrR, 37-40 TaR, an extremely high coronet (55.7-79.0 % head length) with four tips on the corona flat (CoT), and one WS. Hippocampus sindonis Jordan & Snyder, 1901 is diagnosed by 10 TrR, 35-38 TaR, a moderately high coronet (36.3-55.4 % HL) with five CoT, and no WS. A new species, H. haema is described on the basis of 140 specimens, characterized by 10 TrR, 35-38 TaR, a moderately high coronet (34.1 54.9 % head length) with four CoT, and two WS. Hippocampus haema is only known from the Korea Strait, western Kyushu, and East/Japan Sea. Recognition of the three species is supported by differences in mitochondrial DNA fragments (cytochrome b, 16S rRNA, and 12S rRNA). PMID- 29187791 TI - Earwigs from Brazilian caves, with notes on the taxonomic and nomenclatural problems of the Dermaptera (Insecta). AB - Based on samples collected during surveys of Brazilian cave fauna, seven earwig species are reported: Cylindrogaster cavernicola Kamimura, sp. n., Cylindrogaster sp. 1, Cylindrogaster sp. 2, Euborellia janeirensis, Euborellia brasiliensis, Paralabellula dorsalis, and Doru luteipes, as well as four species identified to the (sub)family level. To date, C. cavernicola Kamimura, sp. n. has been recorded only from cave habitats (but near entrances), whereas the other four organisms identified at the species level have also been recorded from non-cave habitats. Wings and female genital structures of Cylindrogaster spp. (Cylindrogastrinae) are examined for the first time. The genital traits, including the gonapophyses of the 8th abdominal segment shorter than those of the 9th segement, and venation of the hind wings of Cylindrogastrinae correspond to those of the members of Diplatyidae and not to Pygidicranidae. This is the first synopsis of cave dwelling earwigs of Brazil, one of the most species-rich areas of Dermaptera in the world.

The paper discusses the validity of the previously proposed lectotype, deposited in the ZMB (Berlin, Germany). Based on the type series deposited in HNHM (Budapest, Hungary) as well as the original description, a new lectotype and 15 paralectotypes from Amazon forest (Sao Paulo de Olivenca, Amazonas) are designated.

PMID- 29187793 TI - A new species of Phrynopus (Amphibia, Anura, Craugastoridae) from upper montane forests and high Andean grasslands of the Pui Pui Protected Forest in central Peru. AB - We describe a new species of Phrynopus from the upper montane forests and high Andean grasslands (puna) of the Pui Pui Protected Forest and its close surroundings (Region Junin, central Peru) and compare it morphologically and genetically with other species of Phrynopus. Phrynopus intisp. n. is known from four localities outside and two localities inside the Pui Pui Protected Forest between 3350 and 3890 m a.s.l. Studied specimens of the new species are characterized by a snout-vent length of 27.2-35.2 mm in males (n = 6), and 40.4 mm in a single female, by having the skin on dorsum and flanks smooth with scattered tubercles, venter smooth, by lacking a tympanum, and males without vocal slits and nuptial pads. In life, the dorsum is pale grayish brown with or without dark brown blotches, or dorsum blackish brown with small yellow flecks, throat, chest and venter are pale grayish brown with salmon mottling, groin is pale grayish brown with salmon colored flecks, and the iris is golden orange with fine dark brown reticulations. The new species is morphologically most similar to Phrynopus kauneorum and P. juninensis. For the latter we describe the coloration in life for a specimen obtained at the type locality. A molecular phylogenetic analysis based on mitochondrial and nuclear DNA sequences inferred that the new species is most closely related to Phrynopus kauneorum, P. miroslawae, P. tautzorum, and an undescribed species distributed at high elevation in Region Pasco, central Peru. PMID- 29187794 TI - Reliability of CKD-EPI predictive equation in estimating chronic kidney disease prevalence in the Croatian endemic nephropathy area. AB - Introduction: Chronic kidney disease (CKD) is a significant public health problem and it is not possible to precisely predict its progression to terminal renal failure. According to current guidelines, CKD stages are classified based on the estimated glomerular filtration rate (eGFR) and albuminuria. Aims of this study were to determine the reliability of predictive equation in estimation of CKD prevalence in Croatian areas with endemic nephropathy (EN), compare the results with non-endemic areas, and to determine if the prevalence of CKD stages 3-5 was increased in subjects with EN. Materials and methods: A total of 1573 inhabitants of the Croatian Posavina rural area from 6 endemic and 3 non-endemic villages were enrolled. Participants were classified according to the modified criteria of the World Health Organization for EN. Estimated GFR was calculated using Chronic Kidney Disease Epidemiology Collaboration equation (CKD-EPI). Results: The results showed a very high CKD prevalence in the Croatian rural area (19%). CKD prevalence was significantly higher in EN then in non EN villages with the lowest eGFR value in diseased subgroup. Conclusions: eGFR correlated significantly with the diagnosis of EN. Kidney function assessment using CKD-EPI predictive equation proved to be a good marker in differentiating the study subgroups, remained as one of the diagnostic criteria for EN. PMID- 29187795 TI - Fasting conditions: Influence of water intake on clinical chemistry analytes. AB - Introduction: Currently available recommendations regarding fasting requirements before phlebotomy do not specify any maximum water intake volume permitted during the fasting period. The aim was to study the effects of 300 mL water intake 1 h before phlebotomy on specific analytes. Materials and methods: Blood was collected from 20 women (median age (min-max): 24 (22 - 50) years) in basal state (T0) and 1 h after 300 mL water intake (T1). Glucose, total proteins (TP), urea, creatinine, cystatin C, total bilirubin (BT), total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides (Tg), uric acid (UA), high-sensitivity C-reactive protein, gamma-glutamyl transferase (GGT), aspartate-aminotransferase (AST), alanine-aminotransferase and lactate dehydrogenase (LD) were studied. Results were analyzed using Wilcoxon test. Mean difference (%) was calculated for each analyte and was further compared with reference change value (RCV). Only mean differences (%) higher than RCV were considered clinically significant. Results: Significant differences (median T0vs median T1, P) were observed for TP (73 vs 74 g/L, 0.001); urea (4.08 vs 4.16 mmol/L, 0.010); BT (12 vs 13 umol/L, 0.021); total cholesterol (4.9 vs 4.9 mmol/L, 0.042); Tg (1.05 vs 1.06 mmol/L, 0.002); UA (260 vs 270 umol/L, 0.006); GGT (12 vs 12 U/L, 0.046); AST (22 vs 24 U/L, 0.001); and LD (364 vs 386 U/L, 0.001). Although the differences observed were statistically significant, they were not indicative of clinically significant changes. Conclusions: A water intake of 300 mL 1 h prior to phlebotomy does not interfere with the analytes studied in the present work. PMID- 29187796 TI - Nurses' knowledge on phlebotomy in tertiary hospitals in China: a cross-sectional multicentric survey. AB - Introduction: In China, phlebotomy practice is mostly executed by nurses instead of phlebotomists. Our hypothesis was that these nurses may lack of knowledge on phlebotomy, especially factors influencing quality of blood samples. This study aims to assess the overall nurses' knowledge on phlebotomy to provide reference for improving blood sampling practice in China. Materials and methods: A survey was conducted involving nurses from 4 regions and 13 hospitals in China. A phlebotomy knowledge questionnaire was designed based on the Clinical and Laboratory Standards Institute H3-A6 guidelines, combining with the situations in China. Descriptive analysis and binary logistic regression analysis were used to analyze the knowledge level and its influencing factors. Results: A total of 3400 questionnaires were distributed and 3077 valid questionnaires were returned, with an effective return rate of 90.5%. The correct rates of patient identification, hand sanitization, patient assessment, tube mixing time, needle disposing location and tube labelling were greater than 90%. However, the correct rates of order of draw (15.5%), definition of an inversion (22.5%), time to release tourniquet (18.5%) and time to change tube (28.5%) were relatively low. Binary logistic regression analysis showed that the correct rates of the aforementioned four questions were mainly related to the regional distribution of the hospitals (P < 0.001). Conclusions: The knowledge level on phlebotomy among Chinese nurses was found unsatisfactory in some areas. An education program on phlebotomy should be developed for Chinese nurses to improve the consistency among different regions and to enhance nurse's knowledge level on phlebotomy. PMID- 29187797 TI - Influence of centrifugation conditions on the results of 77 routine clinical chemistry analytes using standard vacuum blood collection tubes and the new BD Barricor tubes. AB - Introduction: Although centrifugation is performed in almost every blood sample, recommendations on duration and g-force are heterogeneous and mostly based on expert opinions. In order to unify this step in a fully automated laboratory, we aimed to evaluate different centrifugation settings and their influence on the results of routine clinical chemistry analytes. Materials and methods: We collected blood from 41 healthy volunteers into BD Vacutainer PST II-heparin-gel- (LiHepGel), BD Vacutainer SST II-serum-, and BD Vacutainer Barricor heparin-tubes with a mechanical separator (LiHepBar). Tubes were centrifuged at 2000xg for 10 minutes and 3000xg for 7 and 5 minutes, respectively. Subsequently 60 and 21 clinical chemistry analytes were measured in plasma and serum samples, respectively, using a Roche COBAS instrument. Results: High sensitive Troponin T, pregnancy-associated plasma protein A, beta human chorionic gonadotropin and rheumatoid factor had to be excluded from statistical evaluation as many of the respective results were below the measuring range. Except of free haemoglobin (fHb) measurements, no analyte result was altered by the use of shorter centrifugation times at higher g-forces. Comparing LiHepBar to LiHepGel tubes at different centrifugation setting, we found higher lactate-dehydrogenase (LD) (P = 0.003 to < 0.001) and lower bicarbonate values (P = 0.049 to 0.008) in the latter. Conclusions: Serum and heparin samples may be centrifuged at higher speed (3000xg) for a shorter amount of time (5 minutes) without alteration of the analytes tested in this study. When using LiHepBar tubes for blood collection, a separate LD reference value might be needed. PMID- 29187798 TI - Missed detection of significant positive and negative shifts in gentamicin assay: implications for routine laboratory quality practices. AB - Introduction: A product recall was issued for the Roche/Hitachi Cobas Gentamicin II assays on 25th May 2016 in Australia, after a 15 - 20% positive analytical shift was discovered. Laboratories were advised to employ the Thermo Fisher Gentamicin assay as an alternative. Following the reintroduction of the revised assay on 12th September 2016, a second reagent recall was made on 20th March 2017 after the discovery of a 20% negative analytical shift due to erroneous instrument adjustment factor. Materials and methods: The practices of an index laboratory were examined to determine how the analytical shifts evaded detection by routine internal quality control (IQC) and external quality assurance (EQA) systems. The ability of the patient result-based approaches, including moving average (MovAvg) and moving sum of outliers (MovSO) approaches in detecting these shifts were examined. Results: Internal quality control data of the index laboratory were acceptable prior to the product recall. The practice of adjusting IQC target following a change in assay method resulted in the missed negative shift when the revised Roche assay was reintroduced. While the EQA data of the Roche subgroup showed clear negative bias relative to other laboratory methods, the results were considered as possible 'matrix effect'. The MovAvg method detected the positive shift before the product recall. The MovSO did not detect the negative shift in the index laboratory but did so in another laboratory 5 days before the second product recall. Conclusions: There are gaps in current laboratory quality practices that leave room for analytical errors to evade detection. PMID- 29187799 TI - Appropriateness of digoxin measurement in hospitalized patients. AB - Introduction: Measurement of serum digoxin concentrations before steady-state is reached results in a falsely low concentration, and may affect treatment safety. We evaluated the proportion of serum digoxin measurements performed before steady state is reached and the reasons for inappropriate sampling in hospitalized patients. Materials and methods: Electronic medical records of patients hospitalized between January 2011 and December 2015 treated with oral digoxin, that had more than one digoxin measurement were included. Serum digoxin measurements performed before achievement of pharmacological steady state were considered as inappropriate. The chi-square and chi-square for trend tests were used to analyse the relationship between inappropriate measurements and age, gender, diagnosis, inpatient service, serum digoxin, potassium and creatinine concentrations. Results: We evaluated 2065 hospital admissions for 1621 patients and 11,407 digoxin measurements. The time between consecutive measurements was 1.9 +/- 2.4 days and 97% of all measurements were classified as inappropriate. There was no releationship between patient age, gender, serum creatinine concentration and inappropriate measurement. As opposed to expected, inappropriate digoxin measurement was higher when potassium concentrations were within the normal range (P = 0.025). Share of inappropriate determinations of digoxin was higher when concentrations > 2.6 nmol/L were recorded (P < 0.05). These measurements were requested most often in coronary care unit and cardiology department. Conclusions: In our study, inappropriate serum digoxin measurement was found to be very high although only one of the appropriateness criteria was evaluated. The findings reveal the need for some strategies to prevent inappropriate measurements and reduce costs. PMID- 29187800 TI - Reference intervals for six salivary cortisol measures based on the Croatian Late Adolescence Stress Study (CLASS). AB - Introduction: The aim of this nested study is to provide the reference intervals for already published measurements of salivary cortisol from the Croatian Adolescence Stress Study (CLASS). Material and methods: A total of 969 individuals (372 males and 597 females) were included in the reference sample (age range: 18-21 years). Salivary cortisol concentrations were determined by the enzyme immunoassay (LUCIO-Medical ELISA Salivary Cortisol Kit, Nal von Minden, Germany) in the Department of Medical Laboratory Diagnostics, University Hospital Split. Nonparametric statistics were used for calculating the reference intervals (RIs) and 90% confidence intervals (90% CIs). Results: The lower limits of RIs determined by the direct method were higher in females (> 10%) than in males for the cortisol concentrations at awakening (SCC0), 30 to 45 after awakening (SCC30 45) and at bedtime (SCCbedtime). The upper limits of RIs for the SCCbedtime were higher (> 10%) in males than in females. Females also had higher upper limits of RIs for the cortisol awakening response (CAR) and the diurnal cortisol slope (DCS) and higher lower limits of RIs for the CAR and the area under the curve with respect to ground (AUCG). The lower limits of RIs for the DCS were higher in males than in females. Conclusions: Obtained reference values open the arena for introducing salivary bioscience in Croatian clinical laboratory practice and provide important data for better understanding of gender differences in adaptation to stress during late adolescence. PMID- 29187801 TI - Upfront dilution of ferritin samples to reduce hook effect, improve turnaround time and reduce costs. AB - Introduction: Sandwich immunoassays offer advantages in the clinical laboratory but can yield erroneously low results due to hook (prozone) effect, especially with analytes whose concentrations span several orders of magnitude such as ferritin. This study investigated a new approach to reduce the likelihood of hook effect in ferritin immunoassays by performing upfront, five-fold dilutions of all samples for ferritin analysis. The impact of this change on turnaround time and costs were also investigated. Materials and methods: Ferritin concentrations were analysed in routine clinical practice with and without upfront dilutions on Siemens Centaur(r) XP (Siemens Healthineers, Erlang, Germany) immunoanalysers. In addition, one month of baseline data (1026 results) were collected prior to implementing upfront dilutions and one month of data (1033 results) were collected after implementation. Results: Without upfront dilutions, hook effect was observed in samples with ferritin concentrations as low as 86,028 ug/L. With upfront dilutions, samples with ferritin concentrations as high as 126,050 ug/L yielded values greater than the measurement interval and would have been diluted until an accurate value was obtained. The implementation of upfront dilution of ferritin samples led to a decrease in turnaround time from a median of 2 hours and 3 minutes to 1 hour and 18 minutes (P = 0.002). Conclusions: Implementation of upfront dilutions of all ferritin samples reduced the possibility of hook effect, improved turnaround time and saved the cost of performing additional dilutions. PMID- 29187802 TI - Radical distinction: Support for radical left and radical right parties in Europe. AB - Support for radical parties on both the left and right is on the rise, fueling intuition that both radicalisms have similar underpinnings. Indeed, existing studies show that radical left and right voters have overlapping positions and preferences. In this article, however, we focus on the differences in the voting bases of such parties. We show that radical left and right voters have sharply diverging ideological profiles. When it comes to the historical traditions of the 'left' and 'right', these voters differ radically from each other. Both groups express the traditions associated with their mainstream counterparts-particularly with respect to (non-)egalitarian, (non-)altruistic, and (anti-)cosmopolitan values. Such differences also explain why radical left voters tend to be more, not less, educated than mainstream or radical right voters. PMID- 29187803 TI - The financial crisis and the European Parliament: An analysis of the Two-Pack legislation. AB - The left-right line of conflict has been the dominant dimension of decision making in the European Parliament since 1979. A pro-/anti-European Union integration dimension is of secondary importance. Limited evidence exists on the conditions under which these different dimensions matter. This study examines parliamentary decision-making about the so-called Two-Pack, which moved responsibilities about budgetary decision-making to the European Commission. The article uses in-depth interviews, textual analysis of committee debates and roll call voting analysis in order to determine which lines of conflict matter at which stage of decision-making. The evidence indicates that left-right division is dominant in the informal stage preceding committee debates, while both the pro /anti-European Union and the left/right dimensions matter during the committee stage, whereas for plenary votes, the pro-/anti-European Union dimension is crucial. PMID- 29187804 TI - Enforcement tool or strategic instrument? The initiation of ex-post legislative evaluations by the European Commission. AB - Whereas the European Commission officially intends to periodically evaluate all major European Union legislation in force, in practice it only evaluates a minority of major regulations and directives. This article tries to explain the variation in the initiation of such ex-post legislative evaluations by the Commission with the help of two theoretical motives: an enforcement motive and a strategic motive. Based on two novel datasets and binary logistic regression analysis, the results show that the type and complexity of the legislation, the presence of an evaluation clause and the evaluation capacity of the responsible Directorates-General enhance the chances of evaluation. These findings indicate that ex-post legislative evaluations are at least partly driven by the Commission's need to enforce legislation. PMID- 29187805 TI - How friends' involvement in crime affects the risk of offending and victimization. AB - This article examines how friends' involvement in crime influences such involvement in those around them, as offenders or victims, and the extent to which such friendship effects vary with contact frequency, friendship intimacy, and geographical proximity. To test our hypotheses we used four waves from the Dutch panel survey CrimeNL, which includes ego-centered network measures in each wave for respondents aged between 16 and 45. To test our hypotheses, fixed effects panel models were employed. The results show that living in close proximity to delinquent friends increases people's own risk of offending, and daily interaction with these friends decreases the risk of victimization. Victimization is also communicated among friends in their daily interactions. These findings stress the need to consider factors that condition how friendships exert influence on the risk of crime involvement. PMID- 29187806 TI - Absorption ratio of treatment couch and effect on surface and build-up region doses. AB - Aim: In this study, at different fields, energies and gantry angles, treatment couch and rails dose absorption ratio and treatment couch effect on surface and build-up region doses were examined. Background: It is assumed that radiation attenuation is minimal because the carbon fiber couches have low density and it is not generally accounted for during treatment planning. Consequently, it leads to a major dosimetric mistake. Materials and methods: Solid water phantom was used for relative dose measurement. The measurements were done using a Farmer ion chamber with 0.6 cc volume and a parallel plane ion chamber starting from surface with 1 mm depth intervals at 10 * 10 cm2 field, SSD 100 cm. Measurements were taken for situations where the beams intersect the couch and couch rails. Results: Dose absorption ratio of carbon fiber couch obtained at gantry angle of 180 degrees was 1.52%, 0.69%, 0.33% and 0.25% at different field sizes for 6 MV. For 15 MV, this ratio was 0.95%, 0.27%, 0.20% and 0.05%. The absorption ratio is between 3.4% and 1.22% when the beams intersect with couch rails. The couch effect increased surface dose from 14% to 70% for 6 MV and from 11.34% to 53.03% for 15 MV. Conclusions: The results showed that the carbon fiber couch increased surface dose during posterior irradiation. Therefore, the skin-sparing effect of the high energy beams was decreased. If the effect of couch is not considered, it may cause significant differences at dose which reaches the patient and may cause tissue problems such as erythema. PMID- 29187807 TI - Characteristic miRNA expression signature and random forest survival analysis identify potential cancer-driving miRNAs in a broad range of head and neck squamous cell carcinoma subtypes. AB - Aim: To characterize the miRNA expression profile in head and neck squamous cell carcinoma (HNSSC) accounting for a broad range of cancer subtypes and consequently identify an optimal miRNA signature with prognostic value. Background: HNSCC is consistently among the most common cancers worldwide. Its mortality rate is about 50% because of the characteristic aggressive behavior of these cancers and the prevalent late diagnosis. The heterogeneity of the disease has hampered the development of robust prognostic tools with broad clinical utility. Materials and methods: The Cancer Genome Atlas HNSC dataset was used to analyze level 3 miRNA-Seq data from 497 HNSCC patients. Differential expression (DE) analysis was implemented using the limma package and multivariate linear model that adjusted for the confounding effects of age at diagnosis, gender, race, alcohol history, anatomic neoplasm subdivision, pathologic stage, T and N stages, and vital status. Random forest (RF) for survival analysis was implemented using the randomForestSRC package. Results: A characteristic DE miRNA signature of HNSCC, comprised of 11 upregulated (i.e., miR-196b-5p, miR-1269a, miR-196a-5p, miR-4652-3p, miR-210-3p, miR-1293, miR-615-3p, miR-503-5p, miR-455 3p, miR-205-5p, and miR-21-5p) and 9 downregulated (miR-376c-3p, miR-378c, miR 29c-3p, miR-101-3p, miR-195-5p, miR-299-5p, miR-139-5p, miR-6510-3p, miR-375) miRNAs was identified. An optimal RF survival model was built from seven variables including age at diagnosis, miR-378c, miR-6510-3p, stage N, pathologic stage, gender, and race (listed in order of variable importance). Conclusions: The joint differential miRNA expression and survival analysis controlling for multiple confounding covariates implemented in this study allowed for the identification of a previously undetected prognostic miRNA signature characteristic of a broad range of HNSCC. PMID- 29187808 TI - Toward a Cognitive Neural Prosthesis Using Focused Ultrasound. AB - Non-invasive brain stimulation using focused ultrasound has many potential applications as a research and clinical tool, including its incorporation as either an extracorporeal or implantable neural prosthetic. To this end, we investigated the effect of focused ultrasound (FUS) combined with systemically administered microbubbles on visual-motor decision-making behavior in monkeys. We applied FUS to the putamen in one hemisphere to open the blood-brain barrier (BBB), and then tested behavioral performance 3-4 h later. On days when the monkeys were treated with FUS, their decisions were faster and more accurate than days without sonication. The performance improvement suggested both a shift in the decision criterion and an enhancement of the use of sensory evidence in the decision process. FUS also interacted with the effect of a low dose of haloperidol. The findings indicate that a two-minute application of FUS can have a sustained impact on performance of complex cognitive tasks, and may increase the efficacy of psychoactive medications. The results lend further support to the idea that the dorsal striatum plays an integral role in evidence- and reward based decision-making, and provide motivation for incorporating FUS into cognitive neural prosthetic devices. PMID- 29187809 TI - Spatiotemporal Beamforming: A Transparent and Unified Decoding Approach to Synchronous Visual Brain-Computer Interfacing. AB - Brain-Computer Interfaces (BCIs) decode brain activity with the aim to establish a direct communication channel with an external device. Albeit they have been hailed to (re-)establish communication in persons suffering from severe motor- and/or communication disabilities, only recently BCI applications have been challenging other assistive technologies. Owing to their considerably increased performance and the advent of affordable technological solutions, BCI technology is expected to trigger a paradigm shift not only in assistive technology but also in the way we will interface with technology. However, the flipside of the quest for accuracy and speed is most evident in EEG-based visual BCI where it has led to a gamut of increasingly complex classifiers, tailored to the needs of specific stimulation paradigms and use contexts. In this contribution, we argue that spatiotemporal beamforming can serve several synchronous visual BCI paradigms. We demonstrate this for three popular visual paradigms even without attempting to optimizing their electrode sets. For each selectable target, a spatiotemporal beamformer is applied to assess whether the corresponding signal-of-interest is present in the preprocessed multichannel EEG signals. The target with the highest beamformer output is then selected by the decoder (maximum selection). In addition to this simple selection rule, we also investigated whether interactions between beamformer outputs could be employed to increase accuracy by combining the outputs for all targets into a feature vector and applying three common classification algorithms. The results show that the accuracy of spatiotemporal beamforming with maximum selection is at par with that of the classification algorithms and interactions between beamformer outputs do not further improve that accuracy.

AB - Ca2+-triggered SNARE-mediated membrane fusion is essential for neuronal communication. The speed of this process is of particular importance because it sets a time limit to cognitive and physical activities. In this work, we expand the proteoliposome-to-supported bilayer (SBL) fusion assay by successfully incorporating synaptotagmin 1 (Syt1), a major Ca2+ sensor. We report that Syt1 and Ca2+ together can elicit more than a 50-fold increase in the number of membrane fusion events when compared with membrane fusion mediated by SNAREs only. What is remarkable is that ~55% of all vesicle fusion events occurs within 20 ms upon vesicle docking. Furthermore, pre-binding of Syt1 to SNAREs prior to Ca2+ inhibits spontaneous fusion, but intriguingly, this leads to a complete loss of the Ca2+ responsiveness. Thus, our results suggest that there is a productive and a non-productive pathway for Syt1, depending on whether there is a premature interaction between Syt1 and SNAREs. Our results show that Ca2+ binding to Syt1 prior to Syt1's binding to SNAREs may be a prerequisite for the productive pathway. The successful reconstitution of Syt1 activities in the physiological time scale provides new opportunities to test the current mechanistic models for Ca2+-triggered exocytosis. PMID- 29187810 TI - Conditional Loss of Hoxa5 Function Early after Birth Impacts on Expression of Genes with Synaptic Function. AB - Hoxa5 is a member of the Hox gene family that plays critical roles in successive steps of the central nervous system formation during embryonic and fetal development. In the mouse, Hoxa5 was recently shown to be expressed in the medulla oblongata and the pons from fetal stages to adulthood. In these territories, Hoxa5 transcripts are enriched in many precerebellar neurons and several nuclei involved in autonomic functions, while the HOXA5 protein is detected mainly in glutamatergic and GABAergic neurons. However, whether HOXA5 is functionally required in these neurons after birth remains unknown. As a first approach to tackle this question, we aimed at determining the molecular programs downstream of the HOXA5 transcription factor in the context of the postnatal brainstem. A comparative transcriptomic analysis was performed in combination with gene expression localization, using a conditional postnatal Hoxa5 loss-of function mouse model. After inactivation of Hoxa5 at postnatal days (P)1-P4, we established the transcriptome of the brainstem from P21 Hoxa5 conditional mutants using RNA-Seq analysis. One major finding was the downregulation of several genes associated with synaptic function in Hoxa5 mutant specimens including different actors involved in glutamatergic synapse, calcium signaling pathway, and GABAergic synapse. Data were confirmed and extended by reverse transcription quantitative polymerase chain reaction analysis, and the expression of several HOXA5 candidate targets was shown to co-localize with Hoxa5 transcripts in precerebellar nuclei. Together, these new results revealed that HOXA5, through the regulation of key actors of the glutamatergic/GABAergic synapses and calcium signaling, might be involved in synaptogenesis, synaptic transmission, and synaptic plasticity of the cortico-ponto-cerebellar circuitry in the postnatal brainstem. PMID- 29187812 TI - Adrenomedullin Contributes to Age-Related Memory Loss in Mice and Is Elevated in Aging Human Brains. AB - Memory decline is common in elderly individuals and is the hallmark of Alzheimer's disease (AD). Memory failure follows the loss of synaptic contacts in the cerebral cortex and hippocampus, caused in part by cytoskeleton disruption. Adrenomedullin (AM) and its gene-related peptide, proadrenomedullin N-terminal 20 peptide (PAMP), are microtubule-associated proteins (MAP) whose expression has been identified as a potential biomarker for predicting progression from predementia to clinical AD. Here we analyze the connection between AM levels and memory preservation. Mice lacking neuronal AM and PAMP (knockout, KO) and their wild type (WT) littermates were subjected, at different ages, to the novel object recognition test and the contextual fear conditioned test. Aged KO mice have significantly better retention memory than their WT counterparts. This feature was more prominent in females than in males. Prefrontal cortex and hippocampus samples from these animals were subjected to Western blotting for phospho-Tau and acetylated tubulin. Aged female KO mice had significantly less accumulation of phospho-Tau than their WT littermates. In addition, protein extracts from the frontal cortex of non-demented mature (65.10 +/- 3.86 years) and aged (77.14 +/- 2.77 years) human donors were analyzed by Western blotting. Aged human brains had significantly higher levels of AM and lower levels of acetylated tubulin than younger donors. These observations suggest that drugs or interventions that reduce AM/PAMP expression may constitute a new avenue to prevent memory decline during normal aging and in patients suffering moderate AD in high risk of rapid cognitive decline. PMID- 29187814 TI - Olfaction and Pheromones: Uncanonical Sensory Influences and Bulbar Interactions. AB - The rodent main and accessory olfactory systems (AOS) are considered functionally and anatomically segregated information-processing pathways. Each system is devoted to the detection of volatile odorants and pheromones, respectively. However, a growing number of evidences supports a cooperative interaction between them. For instance, at least four non-canonical receptor families (i.e., different from olfactory and vomeronasal receptor families) have been recently discovered. These atypical receptor families are expressed in the sensory organs of the nasal cavity and furnish parallel processing-pathways that detect specific stimuli and mediate specific behaviors as well. Aside from the receptor and functional diversity of these sensory modalities, they converge into a poorly understood bulbar area at the intersection of the main- main olfactory bulb (MOB) and accessory olfactory bulb (AOB) that has been termed olfactory limbus (OL). Given the intimate association the OL with specialized glomeruli (i.e., necklace and modified glomeruli) receiving uncanonical sensory afferences and its interactions with the MOB and AOB, the possibility that OL is a site of non olfactory and atypical vomeronasal sensory decoding is discussed. PMID- 29187813 TI - A miRNA Signature for Cognitive Deficits and Alcohol Use Disorder in Persons Living with HIV/AIDS. AB - HIV-associated neurocognitive disorders (HAND) affects more than half of persons living with HIV-1/AIDS (PLWHA). Identification of biomarkers representing the cognitive status of PLWHA is a critical step for implementation of successful cognitive, behavioral and pharmacological strategies to prevent onset and progression of HAND. However, the presence of co-morbidity factors in PLWHA, the most common being substance abuse, can prevent the identification of such biomarkers. We have optimized a protocol to profile plasma miRNAs using quantitative RT-qPCR and found a miRNA signature with very good discriminatory ability to distinguish PLWHA with cognitive impairment from those without cognitive impairment. Here, we have evaluated this miRNA signature in PLWHA with alcohol use disorder (AUD) at LSU Health Sciences Center (LSUHSC). The results show that AUD is a potential confounding factor for the miRNAs associated with cognitive impairment in PLWHA. Furthermore, we have investigated the miRNA signature associated with cognitive impairment in an independent cohort of PLWHA using plasma samples from the CNS HIV Antiretroviral Therapy Effects Research (CHARTER) program. Despite differences between the two cohorts in socioeconomic status, AUD, and likely misuse of illicit or prescription drugs, we validated a miRNA signature for cognitive deficits found at LSUHSC in the CHARTER samples. PMID- 29187815 TI - Comparative Performance of Linear Multielectrode Probes and Single-Tip Electrodes for Intracortical Microstimulation and Single-Neuron Recording in Macaque Monkey. AB - Intracortical microstimulation (ICMS) is one of the most widely employed techniques for providing causal evidence of the relationship between neuronal activity and specific motor, perceptual, or even cognitive functions. In recent years, several new types of linear multielectrode silicon probes have been developed, allowing researchers to sample neuronal activity at different depths along the same cortical site simultaneously and with high spatial precision. Nevertheless, silicon multielectrode probes have been rarely employed for ICMS studies and, more importantly, it is unknown whether and to what extent they can be used for combined recording and stimulation experiments. Here, we addressed these issues during both acute and chronic conditions. First, we compared the behavioral outcomes of ICMS delivered to the hand region of a monkey's motor cortex with multielectrode silicon probes, commercially available multisite stainless-steel probes and single-tip glass-coated tungsten microelectrodes. The results for all three of the probes were reliable and similar. Furthermore, we tested the impact of long-train ICMS delivered through chronically implanted silicon probes at different time intervals, from 1 to 198 days after ICMS sessions, showing that although the number of recorded neurons decreased over time, in line with previous studies, ICMS did not alter silicon probes' recording capabilities. These findings indicate that in ICMS experiments, the performance of linear multielectrode silicon probes is comparable to that of both single-tip and multielectrode stainless-steel probes, suggesting that the silicon probes can be successfully used for combined recording and stimulation studies in chronic conditions. PMID- 29187816 TI - Differential Effects of Oxytocin on Visual Perspective Taking for Men and Women. AB - Although oxytocin (OXT) has been shown to lead to reduced self-orientation, no study to date has directly and effectively weakened the egocentric tendencies in perspective taking tasks for both men and women. In this double-blind, placebo controlled, mixed design study we investigated the effects of OXT on men and women in visual perspective taking tasks. The results showed that OXT shortened the differences in response time between men and women in all experimental conditions. In addition, after OXT administration, the difference in reaction time between judging from one's own perspective and judging from others' perspectives decreased in female participants; however, this effect was not present in males. This may indicate that under OXT treatment, women have a higher tendency to overcome interference from their position and mindset when judging others' perspectives. However, OXT did not affect participants' accuracy, which is possibility because the used task was not suited to detect performance improvements caused by OXT. In summary, the above results may indicate that OXT could increase perspective-taking abilities through reducing self-bias and increasing the perception of others; furthermore, this trend mainly affected women rather than men. PMID- 29187817 TI - Predicting Long-Term Cognitive Outcome Following Breast Cancer with Pre-Treatment Resting State fMRI and Random Forest Machine Learning. AB - We aimed to determine if resting state functional magnetic resonance imaging (fMRI) acquired at pre-treatment baseline could accurately predict breast cancer related cognitive impairment at long-term follow-up. We evaluated 31 patients with breast cancer (age 34-65) prior to any treatment, post-chemotherapy and 1 year later. Cognitive testing scores were normalized based on data obtained from 43 healthy female controls and then used to categorize patients as impaired or not based on longitudinal changes. We measured clustering coefficient, a measure of local connectivity, by applying graph theory to baseline resting state fMRI and entered these metrics along with relevant patient-related and medical variables into random forest classification. Incidence of cognitive impairment at 1 year follow-up was 55% and was predicted by classification algorithms with up to 100% accuracy (p < 0.0001). The neuroimaging-based model was significantly more accurate than a model involving patient-related and medical variables (p = 0.005). Hub regions belonging to several distinct functional networks were the most important predictors of cognitive outcome. Characteristics of these hubs indicated potential spread of brain injury from default mode to other networks over time. These findings suggest that resting state fMRI is a promising tool for predicting future cognitive impairment associated with breast cancer. This information could inform treatment decision making by identifying patients at highest risk for long-term cognitive impairment.

PMID- 29187819 TI - Binaural Beat: A Failure to Enhance EEG Power and Emotional Arousal. AB - When two pure tones of slightly different frequencies are delivered simultaneously to the two ears, is generated a beat whose frequency corresponds to the frequency difference between them. That beat is known as acoustic beat. If these two tones are presented one to each ear, they still produce the sensation of the same beat, although no physical combination of the tones occurs outside the auditory system. This phenomenon is called binaural beat. In the present study, we explored the potential contribution of binaural beats to the enhancement of specific electroencephalographic (EEG) bands, as previous studies suggest the potential usefulness of binaural beats as a brainwave entrainment tool. Additionally, we analyzed the effects of binaural-beat stimulation on two psychophysiological measures related to emotional arousal: heart rate and skin conductance. Beats of five different frequencies (4.53 Hz -theta-, 8.97 Hz -alpha , 17.93 Hz -beta-, 34.49 Hz -gamma- or 57.3 Hz -upper-gamma) were presented binaurally and acoustically for epochs of 3 min (Beat epochs), preceded and followed by pink noise epochs of 90 s (Baseline and Post epochs, respectively). In each of these epochs, we analyzed the EEG spectral power, as well as calculated the heart rate and skin conductance response (SCR). For all the beat frequencies used for stimulation, no significant changes between Baseline and Beat epochs were observed within the corresponding EEG bands, neither with binaural or with acoustic beats. Additional analysis of spectral EEG topographies yielded negative results for the effect of binaural beats in the scalp distribution of EEG spectral power. In the psychophysiological measures, no changes in heart rate and skin conductance were observed for any of the beat frequencies presented. Our results do not support binaural-beat stimulation as a potential tool for the enhancement of EEG oscillatory activity, nor to induce changes in emotional arousal. PMID- 29187820 TI - A Comprehensive Strategy to Evaluate Compatible Stability of Chinese Medicine Injection and Infusion Solutions Based on Chemical Analysis and Bioactivity Assay. AB - Stability of traditional Chinese medicine injection (TCMI) is an important issue related with its clinical application. TCMI is composed of multi-components, therefore, when evaluating TCMI stability, several marker compounds cannot represent global components or biological activities of TCMI. Till now, when evaluating TCMI stability, method involving the global components or biological activities has not been reported. In this paper, we established a comprehensive strategy composed of three different methods to evaluate the chemical and biological stability of a typical TCMI, Danhong injection (DHI). UHPLC-TQ/MS was used to analyze the stability of marker compounds (SaA, SaB, RA, DSS, PA, CA, and SG) in DHI, UHPLC-QTOF/MS was used to analyze the stability of global components (MW 80-1000 Da) in DHI, and cell based antioxidant capability assay was used to evaluate the bioactivity of DHI. We applied this strategy to assess the compatible stability of DHI and six infusion solutions (GS, NS, GNS, FI, XI, and DGI), which were commonly used in combination with DHI in clinic. GS was the best infusion solution for DHI, and DGI was the worst one based on marker compounds analysis. Based on global components analysis, XI and DGI were the worst infusion solutions for DHI. And based on bioactivity assay, GS was the best infusion solution for DHI, and XI was the worst one. In conclusion, as evaluated by the established comprehensive strategy, GS was the best infusion solution, however, XI and DGI were the worst infusion solutions for DHI. In the compatibility of DHI and XI or DGI, salvianolic acids in DHI would be degraded, resulting in the reduction of original composition and generation of new components, and leading to the changes of biological activities. This is the essence of instability compatibility of DHI and some infusion solutions. Our study provided references for choosing the reasonable infusion solutions for DHI, which could contribute the improvement of safety and efficacy of DHI. Moreover, the established strategy may be applied for the compatible stability evaluation of other TCMIs. PMID- 29187821 TI - Renoprotective Effect of Dipeptidyl Peptidase-4 Inhibitors in Patients with Type 2 Diabetes Mellitus. AB - Diabetic nephropathy is one of three major complications of diabetes mellitus, often leading to chronic renal failure requiring dialysis. Recently developed dipeptidyl peptidase-4 (DPP-4) inhibitors may exhibit renoprotective effects in addition to antihyperglycemic effects. In this study, we retrospectively investigated temporal changes in the renal function index of patients with type 2 diabetes mellitus (DM) and examined the influence of DPP-4 inhibitors on renal function. Patients with type 2 DM (>18 years old) prescribed hypoglycemic agents at Gifu Municipal Hospital for >=3 months between March 2010 and April 2014 were included in the study. Renal function was evaluated as estimated the decline in 12-month glomerular filtration rate from the baseline in patients receiving and not receiving DPP-4 inhibitors. Patient data from the DPP-4 inhibitor-treated (501 patients, 58.6%) and untreated (354, 41.4%) groups were analyzed using multiple logistic regression analysis, as well as Cox proportional-hazards regression analysis (616, 55.6% and 491, 44.4%, for DPP-4 inhibitors-treated and untreated groups). Multiple logistic regression analysis indicated that DPP-4 inhibitors significantly lowered the estimated glomerular filtration rate (eGFR) decline [20% over 12 months; odds ratio (OR), 0.626; 95% confidence interval [CI], 0.409-0.958; P = 0.031]. Similar results were obtained using Cox proportional-hazards regression analysis (hazard ratio [HR], 0.707; 95% CI, 0.572 0.874; P = 0.001). These findings suggest that DPP-4 inhibitors suppress the decrease of estimated glomerular filtration rate in patients with type 2 DM and show a renoprotective effect.

AB - Objective: Despite the indubitable beneficial effect of exercise to prevent of cardiovascular diseases, there is still a lack of studies investigating the impact of exercise in non-ischemic dilated cardiomyopathy. Here, we investigated the impact of voluntary exercise on cardiac function in a mouse model of non ischemic dilated cardiomyopathy (alphaMHC-MerCreMer:Sf/Sf), induced by cardiac specific inactivation of the Serum Response Factor. Materials and Methods: Seven days after tamoxifen injection, 20 alphaMHC-MerCreMer:Sf/Sf mice were assigned to sedentary (n = 8) and exercise (n = 12) groups. Seven additional alphaMHC MerCreMer:Sf/Sf mice without tamoxifen injection were used as control. The exercise group performed 4 weeks of voluntary running on wheel (1.8 +/- 0.12 km/day). Cardiac function, myocardial fibrosis, and mitochondrial energetic pathways were then blindly assessed. Results: Exercised mice exhibited a smaller decrease of left ventricular (LV) fractional shortening and ejection fraction compared to control mice. This was associated with a lower degree of LV remodeling in exercised mice, as shown by a lower LV end-systolic intrerventricular septal and posterior wall thickness decrease from baseline values compared to sedentary mice. Moreover, exercised mice displayed a reduced gene expression of atrial and brain natriuretic factors. These benefits were associated by a reduced level of myocardial fibrosis. In addition, exercised mice exhibited a higher mitochondrial aconitase, voltage-dependent anion-selective channel 1 and PPAR gamma coactivators-1 alpha proteins levels suggesting that the increase of mitochondrial biogenesis and/or metabolism slowed the progression of dilated cardiomyopathy in exercised animals. Conclusions: In conclusion, our results support the role of voluntary exercise to improve outcomes in non ischemic dilated heart failure (HF) and also support its potential for a routine clinical use in the future. PMID- 29187825 TI - Rhynchophylline Ameliorates Endothelial Dysfunction via Src-PI3K/Akt-eNOS Cascade in the Cultured Intrarenal Arteries of Spontaneous Hypertensive Rats. AB - Objectives: To examine the protective effect of Rhynchophylline (Rhy) on vascular endothelial function in spontaneous hypertensive rats (SHRs) and the underlying mechanism. Methods: Intrarenal arteries of SHRs and Wistar rats were suspended in myograph for force measurement. Expression and phosphorylation of endothelial nitric oxide (NO) synthase (eNOS), Akt, and Src kinase (Src) were examined by Western blotting. NO production was assayed by ELISA. Results: Rhy time- and concentration-dependently improved endothelium-dependent relaxation in the renal arteries from SHRs, but had no effect on endothelium-independent relaxation in SHR renal arteries. Wortmannin (an inhibitor of phosphatidylinositol 3-kinase) or PP2 (an inhibitor of Src) inhibited the improvement of relaxation in response to acetylcholine by 12 h-incubation with 300 MUM Rhy. Western blot analysis revealed that Rhy elevated phosphorylations of eNOS, Akt, and Src in SHR renal arteries. Moreover, wortmannin reversed the increased phosphorylations of Akt and eNOS induced by Rhy, but did not affect the phosphorylation of Src. Furthermore, the enhanced phosphorylations of eNOS, Akt, and Src were blunted by PP2. Importantly, Rhy increased NO production and this effect was blocked by inhibition of Src or PI3K/Akt. Conclusion: The present study provides evidences for the first time that Rhy ameliorates endothelial dysfunction in SHRs through the activation of Src-PI3K/Akt-eNOS signaling pathway. PMID- 29187824 TI - The Implication of PGC-1alpha on Fatty Acid Transport across Plasma and Mitochondrial Membranes in the Insulin Sensitive Tissues. AB - PGC-1alpha coactivator plays a decisive role in the maintenance of lipid balance via engagement in numerous metabolic processes (i.e., Krebs cycle, beta oxidation, oxidative phosphorylation and electron transport chain). It constitutes a link between fatty acids import and their complete oxidation or conversion into bioactive fractions through the coordination of both the expression and subcellular relocation of the proteins involved in fatty acid transmembrane movement. Studies on cell lines and/or animal models highlighted the existence of an upregulation of the total and mitochondrial FAT/CD36, FABPpm and FATPs content in skeletal muscle in response to PGC-1alpha stimulation. On the other hand, the association between PGC-1alpha level or activity and the fatty acids transport in the heart and adipocytes is still elusive. So far, the effects of PGC-1alpha on the total and sarcolemmal expression of FAT/CD36, FATP1, and FABPpm in cardiomyocytes have been shown to vary in relation to the type of PPAR that was coactivated. In brown adipose tissue (BAT) PGC-1alpha knockdown was linked with a decreased level of lipid metabolizing enzymes and fatty acid transporters (FAT/CD36, FABP3), whereas the results obtained for white adipose tissue (WAT) remain contradictory. Furthermore, dysregulation in lipid turnover is often associated with insulin intolerance, which suggests the coactivator's potential role as a therapeutic target. PMID- 29187827 TI - The Long-Term Benefits of Positive Self-Presentation via Profile Pictures, Number of Friends and the Initiation of Relationships on Facebook for Adolescents' Self Esteem and the Initiation of Offline Relationships. AB - Social networking sites are a substantial part of adolescents' daily lives. By using a longitudinal approach the current study examined the impact of (a) positive self-presentation, (b) number of friends, and (c) the initiation of online relationships on Facebook on adolescents' self-esteem and their initiation of offline relationships, as well as the mediating role of positive feedback. Questionnaire data were obtained from 217 adolescents (68% girls, mean age 16.7 years) in two waves. Adolescents' positive self-presentation and number of friends were found to be related to a higher frequency of receiving positive feedback, which in turn was negatively associated with self-esteem. However, the number of Facebook friends had a positive impact on self-esteem, and the initiation of online relationships positively influenced the initiation of offline relationships over time, demonstrating that Facebook may be a training ground for increasing adolescents' social skills. Implications and suggestions for future research are provided. PMID- 29187826 TI - Differences in the Thoracic Aorta by Region and Sex in a Murine Model of Marfan Syndrome. AB - Marfan syndrome (MFS) is a hereditary disorder of the connective tissue that causes life-threatening aortic aneurysm, which initiates at the aortic root and can progress into the ascending portion. However, analysis of ascending aorta reactivity in animal models of MFS has remained elusive. Epidemiologic evidence suggests that although MFS is equally prevalent in men and women, men are at a higher risk of aortic complications than non-pregnant women. Nevertheless, there is no experimental evidence to support this hypothesis. The aim of this study was to explore whether there are regional and sex differences in the thoracic aorta function of mice heterozygous for the fibrillin 1 (Fbn1) allele encoding a missense mutation (Fbn1C1039G/+), the most common class of mutation in MFS. Ascending and descending thoracic aorta reactivity was evaluated by wire myography. Ascending aorta mRNA and protein levels, and elastic fiber integrity were assessed by qRT-PCR, Western blotting, and Verhoeff-Van Gieson histological staining, respectively. MFS differently altered reactivity in the ascending and descending thoracic aorta by either increasing or decreasing phenylephrine contractions, respectively. When mice were separated by sex, contractions to phenylephrine increased progressively from 3 to 6 months of age in MFS ascending aortas of males, whereas contractions in females were unchanged. Endothelium dependent relaxation was unaltered in the MFS ascending aorta of either sex; an effect related to augmented endothelium-dependent hyperpolarization-type dilations. In MFS males, the non-selective cyclooxygenase (COX) inhibitor indomethacin prevented the MFS-induced enhancement of phenylephrine contractions linked to increased COX-2 expression. In MFS mice of both sexes, the non selective nitric oxide synthase inhibitor L-NAME revealed negative feedback of nitric oxide on phenylephrine contractions, which was associated with upregulation of eNOS in females. Finally, MFS ascending aortas showed a greater number of elastic fiber breaks than the wild-types, and males exhibited more breaks than females. These results show regional and sex differences in Fbn1C1039G/+ mice thoracic aorta contractility and aortic media injuries. The presence of more pronounced aortic alterations in male mice provides experimental evidence to support that male MFS patients are at increased risk of suffering aortic complications. PMID- 29187828 TI - On the Interpretation and Use of Mediation: Multiple Perspectives on Mediation Analysis. AB - Mediation analysis has become a very popular approach in psychology, and it is one that is associated with multiple perspectives that are often at odds, often implicitly. Explicitly discussing these perspectives and their motivations, advantages, and disadvantages can help to provide clarity to conversations and research regarding the use and refinement of mediation models. We discuss five such pairs of perspectives on mediation analysis, their associated advantages and disadvantages, and their implications: with vs. without a mediation hypothesis, specific effects vs. a global model, directness vs. indirectness of causation, effect size vs. null hypothesis testing, and hypothesized vs. alternative explanations. Discussion of the perspectives is facilitated by a small simulation study. Some philosophical and linguistic considerations are briefly discussed, as well as some other perspectives we do not develop here. PMID- 29187829 TI - Multisensory Motion Perception in 3-4 Month-Old Infants. AB - Human infants begin very early in life to take advantage of multisensory information by extracting the invariant amodal information that is conveyed redundantly by multiple senses. Here we addressed the question as to whether infants can bind multisensory moving stimuli, and whether this occurs even if the motion produced by the stimuli is only illusory. Three- to 4-month-old infants were presented with two bimodal pairings: visuo-tactile and audio-visual. Visuo tactile pairings consisted of apparently vertically moving bars (the Barber Pole illusion) moving in either the same or opposite direction with a concurrent tactile stimulus consisting of strokes given on the infant's back. Audio-visual pairings consisted of the Barber Pole illusion in its visual and auditory version, the latter giving the impression of a continuous rising or ascending pitch. We found that infants were able to discriminate congruently (same direction) vs. incongruently moving (opposite direction) pairs irrespective of modality (Experiment 1). Importantly, we also found that congruently moving visuo tactile and audio-visual stimuli were preferred over incongruently moving bimodal stimuli (Experiment 2). Our findings suggest that very young infants are able to extract motion as amodal component and use it to match stimuli that only apparently move in the same direction.

PMID- 29187832 TI - Isolated Horizontal Gaze Palsy: Observations and Explanations. AB - We present three cases that we suggest require a novel diagnosis and a reconsideration of current understandings of pontine anatomy. In this case series, we highlight a series of patients with monophasic, fully recovering inflammatory lesions in the pontine tegmentum not due to any of the currently recognized causes of this syndrome. We highlight other similar cases in the literature and suggest there may be a particular epitope for an as-yet undiscovered antibody underlying the tropism for this area. We highlight the potential harm of misdiagnosis with relapsing inflammatory or other serious diagnoses with significant adverse impact on the patient. In addition, we propose that this would support a reinterpretation of the currently accepted anatomy of the pontine gaze inputs to the median longitudinal fasciculus and paramedian pontine reticular formation. PMID- 29187831 TI - Learning Where to Look for High Value Improves Decision Making Asymmetrically. AB - Decision making in any brain is imperfect and costly in terms of time and energy. Operating under such constraints, an organism could be in a position to improve performance if an opportunity arose to exploit informative patterns in the environment being searched. Such an improvement of performance could entail both faster and more accurate (i.e., reward-maximizing) decisions. The present study investigated the extent to which human participants could learn to take advantage of immediate patterns in the spatial arrangement of serially presented foods such that a region of space would consistently be associated with greater subjective value. Eye movements leading up to choices demonstrated rapidly induced biases in the selective allocation of visual fixation and attention that were accompanied by both faster and more accurate choices of desired goods as implicit learning occurred. However, for the control condition with its spatially balanced reward environment, these subjects exhibited preexisting lateralized biases for eye and hand movements (i.e., leftward and rightward, respectively) that could act in opposition not only to each other but also to the orienting biases elicited by the experimental manipulation, producing an asymmetry between the left and right hemifields with respect to performance. Potentially owing at least in part to learned cultural conventions (e.g., reading from left to right), the findings herein particularly revealed an intrinsic leftward bias underlying initial saccades in the midst of more immediate feedback-directed processes for which spatial biases can be learned flexibly to optimize oculomotor and manual control in value-based decision making. The present study thus replicates general findings of learned attentional biases in a novel context with inherently rewarding stimuli and goes on to further elucidate the interactions between endogenous and exogenous biases. PMID- 29187833 TI - Transcriptome Analysis on Single Small Yellow Follicles Reveals That Wnt4 Is Involved in Chicken Follicle Selection. AB - Ovarian follicle selection is an important process impacting the laying performance and fecundity of hens, and is regulated by follicle-stimulating hormone (FSH) through binding to its receptor [follicle-stimulating hormone receptor (FSHR)]. In laying hens, the small yellow follicle (6-8 mm in diameter) with the highest expression of FSHR will be recruited into the preovulatory hierarchy during ovarian follicle development. The study of molecular mechanism of chicken follicle selection is helpful for the identification of genes underlying egg-laying traits in chicken and other poultry species. Herein, the transcriptomes of chicken small yellow follicles differing in the mRNA expression of FSHR were compared, and a total of 17,993 genes were identified in 3 pairs of small yellow follicles. The Wnt signaling pathway was significantly enriched in the follicles with the greatest fold change in FSHR expression. In this pathway, the expression level of Wnt4 mRNA was significantly upregulated with a log2(fold change) of 2.12. We further investigated the expression, function, and regulation of Wnt4 during chicken follicle selection and found that Wnt4 mRNA reached its peak in small yellow follicles; Wnt4 stimulated the proliferation of follicular granulosa cells (GCs), increased the expression of StAR and CYP11A1 mRNA in prehierarchical and hierarchical follicles, increased the expression of FSHR mRNA, and decreased the expression of anti-Mullerian hormone and OCLN mRNA. Treatment with FSH significantly increased Wnt4 expression in GCs. Moreover, Wnt4 facilitated the effects of FSH on the production of progesterone (P4) and the mRNA expression of steroidogenic enzyme genes in the GCs of hierarchical follicles, but inhibited the effects of FSH in the GCs of prehierarchical follicles. Collectively, these data suggest that Wnt4 plays an important role in chicken follicle selection by stimulating GC proliferation and steroidogenesis. This study provides a theoretical basis for improving the egg-laying performance of chicken and a reference for the elucidation of the molecular mechanism of follicular selection in mammals.

AB - In oligotrophic regions, such as the Mediterranean Sea, atmospheric deposition has the potential to stimulate heterotrophic prokaryote growth and production in surface waters, especially during the summer stratification period. Previous studies focused on the role of leaching nutrients from mineral particles of Saharan (S) origin, and were restricted to single locations at given times of the year. In this study, we evaluate the effect of atmospheric particles from diverse sources and with a markedly different chemical composition [S dust and anthropogenic (A) aerosols] on marine planktonic communities from three locations of the northwestern Mediterranean with contrasted anthropogenic footprint. Experiments were also carried out at different times of the year, considering diverse initial conditions. We followed the dynamics of the heterotrophic community and a range of biogeochemical and physiological parameters in six experiments. While the effect of aerosols on bacterial abundance was overall low, bacterial heterotrophic production was up to 3.3 and 2.1 times higher in the samples amended with A and S aerosols, respectively, than in the controls. Extracellular enzymatic activities [leu-aminopeptidase (AMA) and beta-glucosidase (beta-Gl)] were also enhanced with aerosols, especially from A origin. AMA and beta-Gl increased up to 7.1 in the samples amended with A aerosols, and up to 1.7 and 2.1 times, respectively, with S dust. The larger stimulation observed with A aerosols might be attributed to their higher content in nitrate. However, the response was variable depending the initial status of the seawater. In addition, we found that both A and S aerosols stimulated bacterial abundance and metabolism significantly more in the absence of competitors and predators. PMID- 29187834 TI - Characterization of Four Novel Bacteriophages Isolated from British Columbia for Control of Non-typhoidal Salmonella in Vitro and on Sprouting Alfalfa Seeds. AB - Alfalfa sprouts have been linked to numerous North American outbreaks of Salmonella in recent years. Conventionally, treatments involving chlorine, heat, and irradiation are used for alfalfa seed sanitation. However, such treatments may be highly variable in their efficacy for pathogen control and/or detrimental to sprout quality, therefore negatively perceived by consumers advocating for natural alternatives. The usage of bacteriophages for pathogen control in sprouts has been previously explored, although with conflicting and inconsistent results. Lytic phages, viral predators of bacteria, represent an attractive approach as they provide several advantages compared to conventional treatments, such as their high specificity for bacterial targets and their ubiquity in nature. In this study, four Salmonella phages were isolated from British Columbia, Canada and characterized with respect to host range, burst size, latent period, and environmental stability to assess their potential to control Salmonella. Phage isolate SI1 showed the greatest host range, highest burst size and shortest latent period, greatest stability across all pH and temperatures and was the most effective in control of S. Enteritidis in vitro. Therefore, SI1 was chosen for treatment of sprouting alfalfa seeds artificially contaminated with S. Enteritidis with a multiplicity of infection (MOI) of ~110 PFU/CFU. A significant (p < 0.05) reduction of 38.3 +/- 3.0% of viable Salmonella cells was observed following two h of phage treatment. On days two to six of the sprouting process, reductions of Salmonella were also observed, but were not significant compared to the control (p > 0.05). It was further demonstrated that the sprout yield was not significantly (p > 0.05) affected by phage treatment. These results highlight the potential of phages recovered from the British Columbia environment for use as biocontrol agents against Salmonella, although differing efficacies in vitro was observed. Moreover, the effectiveness of SI1 to significantly (p < 0.05) control Salmonella on sprouting alfalfa seeds on day 1 of treatment was demonstrated. Although promising, future work should aim to optimize this treatment to achieve more effective, and longer lasting, biocontrol of Salmonella in sprouting alfalfa seeds. PMID- 29187836 TI - Increased Adhesion of Listeria monocytogenes Strains to Abiotic Surfaces under Cold Stress. AB - Food contamination by Listeria monocytogenes remains a major concern for some food processing chains, particularly for ready-to-eat foods, including processed foods. Bacterial adhesion on both biotic and abiotic surfaces is a source of contamination by pathogens that have become more tolerant or even persistent in food processing environments, including in the presence of adverse conditions such as cold and dehydration. The most distinct challenge that bacteria confront upon entry into food processing environments is the sudden downshift in temperature, and the resulting phenotypic effects are of interest. Crystal violet staining and the BioFilm Ring Test(r) were applied to assess the adhesion and biofilm formation of 22 listerial strains from different serogroups and origins under cold-stressed and cold-adapted conditions. The physicochemical properties of the bacterial surface were studied using the microbial adhesion to solvent technique. Scanning electron microscopy was performed to visualize cell morphology and biofilm structure. The results showed that adhesion to stainless steel and polystyrene was increased by cold stress, whereas cold-adapted cells remained primarily in planktonic form. Bacterial cell surfaces exhibited electron donating properties regardless of incubation temperature and became more hydrophilic as temperature decreased from 37 to 4 degrees C. Moreover, the adhesion of cells grown at 4 degrees C correlated with affinity for ethyl acetate, indicating the role of cell surface properties in adhesion. PMID- 29187837 TI - Microbiome Datasets Are Compositional: And This Is Not Optional. AB - Datasets collected by high-throughput sequencing (HTS) of 16S rRNA gene amplimers, metagenomes or metatranscriptomes are commonplace and being used to study human disease states, ecological differences between sites, and the built environment. There is increasing awareness that microbiome datasets generated by HTS are compositional because they have an arbitrary total imposed by the instrument. However, many investigators are either unaware of this or assume specific properties of the compositional data. The purpose of this review is to alert investigators to the dangers inherent in ignoring the compositional nature of the data, and point out that HTS datasets derived from microbiome studies can and should be treated as compositions at all stages of analysis. We briefly introduce compositional data, illustrate the pathologies that occur when compositional data are analyzed inappropriately, and finally give guidance and point to resources and examples for the analysis of microbiome datasets using compositional data analysis. PMID- 29187838 TI - Rv2629 Overexpression Delays Mycobacterium smegmatis and Mycobacteria tuberculosis Entry into Log-Phase and Increases Pathogenicity of Mycobacterium smegmatis in Mice. AB - Objective: The aim of the present study was to explore the potential biological role of Rv2629 in Mycobacterium smegmatis and Mycobacterium tuberculosis.Methods: Recombinant wild type and mutant Rv2629 strains were constructed. Rv2629 expression was evaluated by real-time PCR and western blot. Microarray and interaction network analyses were used to identify the gene interactions associated with wild type and mutant Rv2629. Bacterial growth was assessed in Balb/c mice infected with wild type and mutant Rv2629 strains using CFU assay and histological analysis of the organs. Results: Overexpression of Rv2629 could delay the entry of the Mycobacterium tuberculosis cells into the log-phase, while Rv2629 decreased the number of ribosomes and the expression of uridylate kinase in Mycobacterium smegmatis. The Gene Ontology (GO) and pathway analysis indicated that 122 genes correlated with wild type Rv2629, whereas the Rv2629 mutation led to decrease in the ribosome production, oxidative phosphorylation, and virulence in Mycobacterium tuberculosis. Overexpression of Rv2629 slightly enhanced the drug resistance of Mycobacterium smegmatis to antibiotics, and increased its survival and pathogenicity in Balb/c mice. Conclusion: It is suggested that Rv2629 is involved in the survival of the clinical drug-resistant strain via bacterial growth repression and bacterial persistence induction. PMID- 29187839 TI - The Glutaminase-Dependent System Confers Extreme Acid Resistance to New Species and Atypical Strains of Brucella. AB - Neutralophilic bacteria have developed specific mechanisms to cope with the acid stress encountered in environments such as soil, fermented foods, and host compartments. In Escherichia coli, the glutamate decarboxylase (Gad)-dependent system is extremely efficient: it requires the concerted action of glutamate decarboxylase (GadA/GadB) and of the glutamate (Glu)/gamma-aminobutyrate antiporter, GadC. Notably, this system is operative also in new strains/species of Brucella, among which Brucella microti, but not in the "classical" species, with the exception of marine mammals strains. Recently, the glutaminase-dependent system (named AR2_Q), relying on the deamination of glutamine (Gln) into Glu and on GadC activity, was described in E. coli. In Brucella genomes, a putative glutaminase (glsA)-coding gene is located downstream of the gadBC genes. We found that in B. microti these genes are expressed as a polycistronic transcript. Moreover, using a panel of Brucella genus-representative strains, we show that the AR2_Q system protects from extreme acid stress (pH <=2.5), in the sole presence of Gln, only the Brucella species/strains predicted to have functional glsA and gadC. Indeed, mutagenesis approaches confirmed the involvement of glsA and gadC of B. microti in AR2_Q and that the acid-sensitive phenotype of B. abortus can be ascribed to a Ser248Leu substitution in GlsA, leading to loss of glutaminase activity. Furthermore, we found that the gene BMI_II339, of unknown function and downstream of the gadBC-glsA operon, positively affects Gad- and GlsA-dependent AR. Thus, we identified novel determinants that allow newly discovered and marine mammals Brucella strains to be better adapted to face hostile acidic environments. As for significance, this work may contribute to the understanding of the host preferences of Brucella species and opens the way to alternative diagnostic targets in epidemiological surveillance of brucellosis. PMID- 29187840 TI - Prion-Like Domains in Phagobiota. AB - Prions are molecules characterized by self-propagation, which can undergo a conformational switch leading to the creation of new prions. Prion proteins have originally been associated with the development of mammalian pathologies; however, recently they have been shown to contribute to the environmental adaptation in a variety of prokaryotic and eukaryotic organisms. Bacteriophages are widespread and represent the important regulators of microbiota homeostasis and have been shown to be diverse across various bacterial families. Here, we examined whether bacteriophages contain prion-like proteins and whether these prion-like protein domains are involved in the regulation of homeostasis. We used a computational algorithm, prion-like amino acid composition, to detect prion like domains in 370,617 publicly available bacteriophage protein sequences, which resulted in the identification of 5040 putative prions. We analyzed a set of these prion-like proteins, and observed regularities in their distribution across different phage families, associated with their interactions with the bacterial host cells. We found that prion-like domains could be found across all phages of various groups of bacteria and archaea. The results obtained in this study indicate that bacteriophage prion-like proteins are predominantly involved in the interactions between bacteriophages and bacterial cell, such as those associated with the attachment and penetration of bacteriophage in the cell, and the release of the phage progeny. These data allow the identification of phage prion-like proteins as novel regulators of the interactions between bacteriophages and bacterial cells. PMID- 29187841 TI - Genome Comparison of Erythromycin Resistant Campylobacter from Turkeys Identifies Hosts and Pathways for Horizontal Spread of erm(B) Genes. AB - Pathogens in the genus Campylobacter are the most common cause of food-borne bacterial gastro-enteritis. Campylobacteriosis, caused principally by Campylobacter jejuni and Campylobacter coli, is transmitted to humans by food of animal origin, especially poultry. As for many pathogens, antimicrobial resistance in Campylobacter is increasing at an alarming rate. Erythromycin prescription is the treatment of choice for clinical cases requiring antimicrobial therapy but this is compromised by mobility of the erythromycin resistance gene erm(B) between strains. Here, we evaluate resistance to six antimicrobials in 170 Campylobacter isolates (133 C. coli and 37 C. jejuni) from turkeys. Erythromycin resistant isolates (n = 85; 81 C. coli and 4 C. jejuni) were screened for the presence of the erm(B) gene, that has not previously been identified in isolates from turkeys. The genomes of two positive C. coli isolates were sequenced and in both isolates the erm(B) gene clustered with resistance determinants against aminoglycosides plus tetracycline, including aad9, aadE, aph(2")-IIIa, aph(3')-IIIa, and tet(O) genes. Comparative genomic analysis identified identical erm(B) sequences among Campylobacter from turkeys, Streptococcus suis from pigs and Enterococcus faecium and Clostridium difficile from humans. This is consistent with multiple horizontal transfer events among different bacterial species colonizing turkeys. This example highlights the potential for dissemination of antimicrobial resistance across bacterial species boundaries which may compromise their effectiveness in antimicrobial therapy. PMID- 29187842 TI - Low Microbial Diversity and Abnormal Microbial Succession Is Associated with Necrotizing Enterocolitis in Preterm Infants. AB - Despite increased efforts, the diverse etiologies of Necrotizing Enterocolitis (NEC) have remained largely elusive. Clinical predictors of NEC remain ill defined and currently lack sufficient specificity. The development of a thorough understanding of initial gut microbiota colonization pattern in preterm infants might help to improve early detection or prediction of NEC and its associated morbidities. Here we compared the fecal microbiota successions, microbial diversity, abundance and structure of newborns that developed NEC with preterm controls. A 16S rRNA based microbiota analysis was conducted in a total of 132 fecal samples that included the first stool (meconium) up until the 5th week of life or NEC diagnosis from 40 preterm babies (29 controls and 11 NEC cases). A single phylotype matching closest to the Enterobacteriaceae family correlated strongly with NEC. In DNA from the sample with the greatest abundance of this phylotype additional shotgun metagenomic sequencing revealed Citrobacter koseri and Klebsiella pneumoniae as the dominating taxa. These two taxa might represent suitable microbial biomarker targets for early diagnosis of NEC. In NEC cases, we further detected lower microbial diversity and an abnormal succession of the microbial community before NEC diagnosis. Finally, we also detected a disruption in anaerobic microorganisms in the co-occurrence network of meconium samples from NEC cases. Our data suggest that a strong dominance of Citrobacter koseri and/or Klebsiella pneumoniae, low diversity, low abundance of Lactobacillus, as well as an altered microbial-network structure during the first days of life, correlate with NEC risk in preterm infants. Confirmation of these findings in other hospitals might facilitate the development of a microbiota based screening approach for early detection of NEC. PMID- 29187843 TI - Profiling of Oral Microbiota in Early Childhood Caries Using Single-Molecule Real Time Sequencing. AB - Background: Alterations of oral microbiota are the main cause of the progression of caries. The goal of this study was to characterize the oral microbiota in childhood caries based on single-molecule real-time sequencing. Methods: A total of 21 preschoolers, aged 3-5 years old with severe early childhood caries, and 20 age-matched, caries-free children as controls were recruited. Saliva samples were collected, followed by DNA extraction, Pacbio sequencing, and phylogenetic analyses of the oral microbial communities. Results: Eight hundred and seventy six species derived from 13 known bacterial phyla and 110 genera were detected from 41 children using Pacbio sequencing. At the species level, 38 species, including Veillonella spp., Streptococcus spp., Prevotella spp., and Lactobacillus spp., showed higher abundance in the caries group compared to the caries-free group (p < 0.05). The core microbiota at the genus and species levels was more stable in the caries-free micro-ecological niche. At follow-up, oral examinations 6 months after sample collection, development of new dental caries was observed in 5 children (the transitional group) among the 21 caries free children. Compared with the caries-free children, in the transitional and caries groups, 6 species, which were more abundant in the caries-free group, exhibited a relatively low abundance in both the caries group and the transitional group (p < 0.05). We conclude that Abiotrophia spp., Neisseria spp., and Veillonella spp., might be associated with healthy oral microbial ecosystem. Prevotella spp., Lactobacillus spp., Dialister spp., and Filifactor spp. may be related to the pathogenesis and progression of dental caries. PMID- 29187844 TI - speG Is Required for Intracellular Replication of Salmonella in Various Human Cells and Affects Its Polyamine Metabolism and Global Transcriptomes. AB - The speG gene has been reported to regulate polyamine metabolism in Escherichia coli and Shigella, but its role in Salmonella remains unknown. Our preliminary studies have revealed that speG widely affects the transcriptomes of infected in vitro M and Caco-2 cells and that it is required for the intracellular replication of Salmonella enterica serovar Typhimurium (S. Typhimurium) in HeLa cells. In this study, we demonstrated that speG plays a time-dependent and cell type-independent role in the intracellular replication of S. Typhimurium. Moreover, high-performance liquid chromatography (HPLC) of four major polyamines demonstrated putrescine, spermine, and cadaverine as the leading polyamines in S. Typhimurium. The deletion of speG significantly increased the levels of the three polyamines in intracellular S. Typhimurium, suggesting the inhibitory effect of speG on the biosynthesis of these polyamines. The deletion of speG was associated with elevated levels of these polyamines in the attenuated intracellular replication of S. Typhimurium in host cells. This result was subsequently validated by the dose-dependent suppression of intracellular proliferation after the addition of the polyamines. Furthermore, our RNA transcriptome analysis of S. Typhimurium SL1344 and its speG mutant outside and inside Caco-2 cells revealed that speG regulates the genes associated with flagellar biosynthesis, fimbrial expression, and functions of types III and I secretion systems. speG also affects the expression of genes that have been rarely reported to correlate with polyamine metabolism in Salmonella, including those associated with the periplasmic nitrate reductase system, glucarate metabolism, the phosphotransferase system, cytochromes, and the succinate reductase complex in S. Typhimurium in the mid-log growth phase, as well as those in the ilv-leu and histidine biosynthesis operons of intracellular S. Typhimurium after invasion in Caco-2 cells. In the present study, we characterized the phenotypes and transcriptome effects of speG in S. Typhimurium and reviewed the relevant literature to facilitate a more comprehensive understanding of the potential role of speG in the polyamine metabolism and virulence regulation of Salmonella. PMID- 29187845 TI - Loss of Genome Fidelity: Beta HPVs and the DNA Damage Response. AB - While the role of genus alpha human papillomaviruses in the tumorigenesis and tumor maintenance of anogenital and oropharyngeal cancers is well-established, the role of genus beta human papilloviruses (beta-HPVs) in non-melanoma skin cancers (NMSCs) is less certain. Persistent beta-HPV infections cause NMSCs in sun-exposed skin of people with a rare genetic disorder, epidermodysplasia verruciformis. However, beta-HPV infections in people without epidermodysplasia verruciformis are typically transient. Further, beta-HPV gene expression is not necessary for tumor maintenance in the general population as on average there is fewer than one copy of the beta-HPV genome per cell in NMSC tumor biopsies. Cell culture, epidemiological, and mouse model experiments support a role for beta-HPV infections in the initiation of NMSCs through a "hit and run" mechanism. The virus is hypothesized to act as a cofactor, augmenting the genome destabilizing effects of UV. Supporting this idea, two beta-HPV proteins (beta-HPV E6 and E7) disrupt the cellular response to UV exposure and other genome destabilizing events by abrogating DNA repair and deregulating cell cycle progression. The aberrant damage response increases the likelihood of oncogenic mutations capable of driving tumorigenesis independent of a sustained beta-HPV infection or continued viral protein expression. This review summarizes what is currently known about the deleterious effects of beta-HPV on genome maintenance in the context of the virus's putative role in NMSC initiation. PMID- 29187847 TI - A Multilayered Control of the Human Survival Motor Neuron Gene Expression by Alu Elements. AB - Humans carry two nearly identical copies of Survival Motor Neuron gene: SMN1 and SMN2. Mutations or deletions of SMN1, which codes for SMN, cause spinal muscular atrophy (SMA), a leading genetic disease associated with infant mortality. Aberrant expression or localization of SMN has been also implicated in other pathological conditions, including male infertility, inclusion body myositis, amyotrophic lateral sclerosis and osteoarthritis. SMN2 fails to compensate for the loss of SMN1 due to skipping of exon 7, leading to the production of SMNDelta7, an unstable protein. In addition, SMNDelta7 is less functional due to the lack of a critical C-terminus of the full-length SMN, a multifunctional protein. Alu elements are specific to primates and are generally found within protein coding genes. About 41% of the human SMN gene including promoter region is occupied by more than 60 Alu-like sequences. Here we discuss how such an abundance of Alu-like sequences may contribute toward SMA pathogenesis. We describe the likely impact of Alu elements on expression of SMN. We have recently identified a novel exon 6B, created by exonization of an Alu-element located within SMN intron 6. Irrespective of the exon 7 inclusion or skipping, transcripts harboring exon 6B code for the same SMN6B protein that has altered C terminus compared to the full-length SMN. We have demonstrated that SMN6B is more stable than SMNDelta7 and likely functions similarly to the full-length SMN. We discuss the possible mechanism(s) of regulation of SMN exon 6B splicing and potential consequences of the generation of exon 6B-containing transcripts. PMID- 29187846 TI - To Be or Not To Be T4: Evidence of a Complex Evolutionary Pathway of Head Structure and Assembly in Giant Salmonella Virus SPN3US. AB - Giant Salmonella phage SPN3US has a 240-kb dsDNA genome and a large complex virion composed of many proteins for which the functions of most are undefined. We recently determined that SPN3US shares a core set of genes with related giant phages and sequenced and characterized 18 amber mutants to facilitate its use as a genetic model system. Notably, SPN3US and related giant phages contain a bolus of ejection proteins within their heads, including a multi-subunit virion RNA polymerase (vRNAP), that enter the host cell with the DNA during infection. In this study, we characterized the SPN3US virion using mass spectrometry to gain insight into its head composition and the features that its head shares with those of related giant phages and with T4 phage. SPN3US has only homologs to the T4 proteins critical for prohead shell formation, the portal and major capsid proteins, as well as to the major enzymes essential for head maturation, the prohead protease and large terminase subunit. Eight of ~50 SPN3US head proteins were found to undergo proteolytic processing at a cleavage motif by the prohead protease gp245. Gp245 undergoes auto-cleavage of its C-terminus, suggesting this is a conserved activation and/or maturation feature of related phage proteases. Analyses of essential head gene mutants showed that the five subunits of the vRNAP must be assembled for any subunit to be incorporated into the prohead, although the assembled vRNAP must then undergo subsequent major conformational rearrangements in the DNA packed capsid to allow ejection through the ~30 A diameter tail tube for transcription from the injected DNA. In addition, ejection protein candidate gp243 was found to play a critical role in head assembly. Our analyses of the vRNAP and gp243 mutants highlighted an unexpected dichotomy in giant phage head maturation: while all analyzed giant phages have a homologous protease that processes major capsid and portal proteins, processing of ejection proteins is not always a stable/defining feature. Our identification in SPN3US, and related phages, of a diverged paralog to the prohead protease further hints toward a complicated evolutionary pathway for giant phage head structure and assembly. PMID- 29187848 TI - Kaempferol Inhibits the Primary Attachment Phase of Biofilm Formation in Staphylococcus aureus. AB - The ability to form biofilms on surfaces makes Staphylococcus aureus the main pathogenic factor in implanted medical device infections. The aim of this study was to discover a biofilm inhibitor distinct from the antibiotics used to prevent infections resulting from S. aureus biofilms. Here, we describe kaempferol, a small molecule with anti-biofilm activity that specifically inhibited the formation of S. aureus biofilms. Crystal violet (CV) staining and fluorescence microscopy clearly showed that 64 MUg/ml kaempferol inhibited biofilm formation by 80%. Meanwhile, the minimum inhibitory concentration (MIC) and growth curve results indicated that kaempferol had no antibacterial activity against the tested bacterial strain. Kaempferol inhibited the primary attachment phase of biofilm formation, as determined by a fibrinogen-binding assay. Moreover, a fluorescence resonance energy transfer (FRET) assay and quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) analyses revealed that kaempferol reduced the activity of S. aureus sortaseA (SrtA) and the expression of adhesion-related genes. Based on these results, kaempferol provides a starting point for the development of novel anti-biofilm drugs, which may decrease the risk of bacterial drug resistance, to prevent S. aureus biofilm-related infections. PMID- 29187849 TI - Quantification of Inter-Sample Differences in T-Cell Receptor Repertoires Using Sequence-Based Information. AB - Inter-sample comparisons of T-cell receptor (TCR) repertoires are crucial for gaining a better understanding of the immunological states determined by different collections of T cells from different donor sites, cell types, and genetic and pathological backgrounds. For quantitative comparison, most previous studies utilized conventional methods in ecology, which focus on TCR sequences that overlap between pairwise samples. Some recent studies attempted another approach that is categorized into Poisson abundance models using the abundance distribution of observed TCR sequences. However, these methods ignore the details of the measured sequences and are consequently unable to identify sub-repertoires that might have important contributions to the observed inter-sample differences. Moreover, the sparsity of sequence data due to the huge diversity of repertoires hampers the performance of these methods, especially when few overlapping sequences exist. In this paper, we propose a new approach for REpertoire COmparison in Low Dimensions (RECOLD) based on TCR sequence information, which can estimate the low-dimensional structure by embedding the pairwise sequence dissimilarities in high-dimensional sequence space. The inter-sample differences between repertoires are then quantified by information-theoretic measures among the distributions of data estimated in the embedded space. Using datasets of mouse and human TCR repertoires, we demonstrate that RECOLD can accurately identify the inter-sample hierarchical structures, which have a good correspondence with our intuitive understanding about sample conditions. Moreover, for the dataset of transgenic mice that have strong restrictions on the diversity of their repertoires, our estimated inter-sample structure was consistent with the structure estimated by previous methods based on abundance or overlapping sequence information. For the dataset of human healthy donors and Sezary syndrome patients, our method also showed robust estimation performance even under the condition of high sparsity in TCR sequences, while previous studies failed to estimate the structure. In addition, we identified the sequences that contribute to the pairwise-sample differences between the repertoires with the different genetic backgrounds of mice. Such identification of the sequences contributing to variation in immune cell repertoires may provide substantial insight for the development of new immunotherapies and vaccines. PMID- 29187850 TI - Effect of Roux-en-Y Bariatric Surgery on Lipoproteins, Insulin Resistance, and Systemic and Vascular Inflammation in Obesity and Diabetes. AB - Purpose: Obesity is a major modifiable risk factor for cardiovascular disease. Bariatric surgery is considered to be the most effective treatment option for weight reduction in obese patients with and without type 2 diabetes (T2DM). Objective: To evaluate changes in lipoproteins, insulin resistance, mediators of systemic and vascular inflammation, and endothelial dysfunction following Roux-en Y bariatric surgery in obese patients with and without diabetes. Materials and methods: Lipoproteins, insulin resistance, mediators of systemic and vascular inflammation, and endothelial dysfunction were measured in 37 obese patients with (n = 17) and without (n = 20) T2DM, before and 6 and 12 months after Roux-en-Y bariatric surgery. Two way between subject ANOVA was carried out to study the interaction between independent variables (time since surgery and presence of diabetes) and all dependent variables. Results: There was a significant effect of time since surgery on (large effect size) weight, body mass index (BMI), waist circumference, triglycerides (TG), small-dense LDL apolipoprotein B (sdLDL ApoB), HOMA-IR, CRP, MCP-1, ICAM-1, E-selectin, P-selectin, leptin, and adiponectin. BMI and waist circumference had the largest impact of time since surgery. The effect of time since surgery was noticed mostly in the first 6 months. Absence of diabetes led to a significantly greater reduction in total cholesterol, low density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol although the effect size was small to medium. There was a greater reduction in TG and HOMA-IR in patients with diabetes with a small effect size. No patients were lost to follow up. Conclusion: Lipoproteins, insulin resistance, mediators of systemic and vascular inflammation, and endothelial dysfunction improve mostly 6 months after bariatric surgery in obese patients with and without diabetes.

AB - Multiple sclerosis (MS) is characterized by macrophage accumulation and inflammatory infiltrates into the CNS contributing to demyelination. Because purinergic P2X7 receptor (P2X7R) is known to be abundantly expressed on cells of the hematopoietic lineage and of the nervous system, we further investigated its phenotypic expression in MS and experimental autoimmune encephalomyelitis conditions. By quantitative reverse transcription polymerase chain reaction and flow cytometry, we analyzed the P2X7R expression in human mononuclear cells of peripheral blood from stable and acute relapsing-remitting MS phases. Human monocytes were also challenged in vitro with pro-inflammatory stimuli such as the lipopolysaccharide, or the P2X7R preferential agonist 2'(3')-O-(4 Benzoylbenzoyl)adenosine 5'-triphosphate, before evaluating P2X7R protein expression. Finally, by immunohistochemistry and immunofluorescence confocal analysis, we investigated the P2X7R expression in frontal cortex from secondary progressive MS cases. We demonstrated that P2X7R is present and inhibited on peripheral monocytes isolated from MS donors during the acute phase of the disease, moreover it is down-regulated in human monocytes after pro-inflammatory stimulation in vitro. P2X7R is instead up-regulated on astrocytes in the parenchyma of frontal cortex from secondary progressive MS patients, concomitantly with monocyte chemoattractant protein-1 chemokine, while totally absent from microglia/macrophages or oligodendrocytes, despite the occurrence of inflammatory conditions. Our results suggest that inhibition of P2X7R on monocytes and up-regulation in astrocytes might contribute to sustain inflammatory mechanisms in MS. By acquiring further knowledge about P2X7R dynamics and identifying P2X7R as a potential marker for the disease, we expect to gain insights into the molecular pathways of MS. PMID- 29187853 TI - Fine-Tuning of Optimal TCR Signaling in Tumor-Redirected CD8 T Cells by Distinct TCR Affinity-Mediated Mechanisms. AB - Redirecting CD8 T cell immunity with self/tumor-specific affinity-matured T cell receptors (TCRs) is a promising approach for clinical adoptive T cell therapy, with the aim to improve treatment efficacy. Despite numerous functional-based studies, little is known about the characteristics of TCR signaling (i.e., intensity, duration, and amplification) and the regulatory mechanisms underlying optimal therapeutic T cell responses. Using a panel of human SUP-T1 and primary CD8 T cells engineered with incremental affinity TCRs against the cancer-testis antigen NY-ESO-1, we found that upon activation, T cells with optimal-affinity TCRs generated intense and sustained proximal (CD3zeta, LCK) signals associated with distal (ERK1/2) amplification-gain and increased function. In contrast, in T cells with very high affinity TCRs, signal initiation was rapid and strong yet only transient, resulting in poor MAPK activation and low proliferation potential even at high antigen stimulation dose. Under resting conditions, the levels of surface TCR/CD3epsilon, CD8beta, and CD28 expression and of CD3zeta phosphorylation were significantly reduced in those hyporesponsive cells, suggesting the presence of TCR affinity-related activation thresholds. We also show that SHP phosphatases were involved along the TCR affinity gradient, but displayed spatially distinct regulatory roles. While PTPN6/SHP-1 phosphatase activity controlled TCR signaling initiation and subsequent amplification by counteracting CD3zeta and ERK1/2 phosphorylation, PTPN11/SHP-2 augmented MAPK activation without affecting proximal TCR signaling. Together, our findings indicate that optimal TCR signaling can be finely tuned by TCR affinity-dependent SHP-1 and SHP-2 activity, and this may readily be determined at the TCR/CD3 complex level. We propose that these TCR affinity-associated regulations represent potential protective mechanisms preventing high affinity TCR-mediated autoimmune diseases. PMID- 29187854 TI - An Analysis of Natural T Cell Responses to Predicted Tumor Neoepitopes. AB - Personalization of cancer immunotherapies such as therapeutic vaccines and adoptive T-cell therapy may benefit from efficient identification and targeting of patient-specific neoepitopes. However, current neoepitope prediction methods based on sequencing and predictions of epitope processing and presentation result in a low rate of validation, suggesting that the determinants of peptide immunogenicity are not well understood. We gathered published data on human neopeptides originating from single amino acid substitutions for which T cell reactivity had been experimentally tested, including both immunogenic and non immunogenic neopeptides. Out of 1,948 neopeptide-HLA (human leukocyte antigen) combinations from 13 publications, 53 were reported to elicit a T cell response. From these data, we found an enrichment for responses among peptides of length 9. Even though the peptides had been pre-selected based on presumed likelihood of being immunogenic, we found using NetMHCpan-4.0 that immunogenic neopeptides were predicted to bind significantly more strongly to HLA compared to non-immunogenic peptides. Investigation of the HLA binding strength of the immunogenic peptides revealed that the vast majority (96%) shared very strong predicted binding to HLA and that the binding strength was comparable to that observed for pathogen derived epitopes. Finally, we found that neopeptide dissimilarity to self is a predictor of immunogenicity in situations where neo- and normal peptides share comparable predicted binding strength. In conclusion, these results suggest new strategies for prioritization of mutated peptides, but new data will be needed to confirm their value.

AB - Progression of human immunodeficiency virus type-1 (HIV-1) infection in children is faster than adults. HIV-1 subtype C is responsible for more than 50% of the infections globally and more than 90% infections in India. To date, there is no effective vaccine against HIV-1. Recent animal studies and human Phase I trials showed promising results of the protective effect of anti-HIV-1 broadly neutralizing antibodies (bnAbs). Interaction between CD4 binding site (CD4bs) on the HIV-1 envelope glycoprotein and CD4 receptor on the host immune cells is the primary event leading to HIV-1 infection. The CD4bs is a highly conserved region, comprised of a conformational epitope, and is a potential target of bnAbs such as VRC01 that is presently under human clinical trials. Recombinant scFvs can access masked epitopes due to their small size and have shown the potential to inhibit viral replication and neutralize a broad range of viruses. Pediatric viruses are resistant to many of the existing bnAbs isolated from adults. Therefore, in this study, pooled peripheral blood mononuclear cells from 9 chronically HIV-1 subtype C infected pediatric cross-neutralizers whose plasma antibodies exhibited potent and cross-neutralizing activity were used to construct a human anti-HIV-1 scFv phage library of 9 * 108 individual clones. Plasma mapping using CD4bs-specific probes identified the presence of CD4bs directed antibodies in 4 of these children. By extensive biopanning of the library with CD4bs-specific antigen RSC3 core protein, we identified two cross-neutralizing scFv monoclonals 2B10 and 2E4 demonstrating a neutralizing breadth and GMT of 77%, 17.9 ug/ml and 32%, 51.2 ug/ml, respectively, against a panel of 49 tier 1, 2 and 3 viruses. Both scFvs competed with anti-CD4bs bnAb VRC01 confirming their CD4bs epitope specificity. The 2B10 scFv was effective in neutralizing the 7 subtype C and subtype A pediatric viruses tested. Somatic hypermutations in the VH gene of scFvs (10.1 11.1%) is comparable with that of the adult antibodies. These cross-neutralizing CD4bs-directed scFvs can serve as potential reagents for passive immunotherapy. A combination of cross-neutralizing scFvs of diverse specificities with antiretroviral drugs may be effective in suppressing viremia at an early stage of HIV-1 infection and prevent disease progression. PMID- 29187856 TI - A Role for Iodide and Thyroglobulin in Modulating the Function of Human Immune Cells. AB - Iodine is an essential element required for the function of all organ systems. Although the importance of iodine in thyroid hormone synthesis and reproduction is well known, its direct effects on the immune system are elusive. Human leukocytes expressed mRNA of iodide transporters (NIS and PENDRIN) and thyroid related proteins [thyroglobulin (TG) and thyroid peroxidase (TPO)]. The mRNA levels of PENDRIN and TPO were increased whereas TG transcripts were decreased post leukocyte activation. Flow cytometric analysis revealed that both PENDRIN and NIS were expressed on the surface of leukocyte subsets with the highest expression occurring on monocytes and granulocytes. Treatment of leukocytes with sodium iodide (NaI) resulted in significant changes in immunity-related transcriptome with an emphasis on increased chemokine expression as probed with targeted RNASeq. Similarly, treatment of leukocytes with NaI or Lugol's iodine induced increased protein production of both pro- and anti-inflammatory cytokines. These alterations were not attributed to iodide-induced de novo thyroid hormone synthesis. However, upon incubation with thyroid-derived TG, primary human leukocytes but not Jurkat T cells released thyroxine and triiodothyronine indicating that immune cells could potentially influence thyroid hormone balance. Overall, our studies reveal the novel network between human immune cells and thyroid-related molecules and highlight the importance of iodine in regulating the function of human immune cells.

AB - The runner bean is a legume species from Mesoamerica closely related to common bean (Phaseolus vulgaris). It is a perennial species, but it is usually cultivated in small-scale agriculture as an annual crop for its dry seeds and edible immature pods. Unlike the common bean, P. coccineus has received little attention from a genetic standpoint. In this work we aim to (1) provide information about the domestication history and domestication events of P. coccineus; (2) examine the distribution and level of genetic diversity in wild and cultivated Mexican populations of this species; and, (3) identify candidate loci to natural and artificial selection. For this, we generated genotyping by sequencing data (42,548 SNPs) from 242 individuals of P. coccineus and the domesticated forms of the closely related species P. vulgaris (20) and P. dumosus (35). Eight genetic clusters were detected, of which half corresponds to wild populations and the rest to domesticated plants. The cultivated populations conform a monophyletic clade, suggesting that only one domestication event occurred in Mexico, and that it took place around populations of the Trans Mexican Volcanic Belt. No difference between wild and domesticated levels of genetic diversity was detected and effective population sizes are relatively high, supporting a weak genetic bottleneck during domestication. Most populations presented an excess of heterozygotes, probably due to inbreeding depression. One population of P. coccineus subsp. striatus had the greatest excess and seems to be genetically isolated despite being geographically close to other wild populations. Contrasting with previous studies, we did not find evidence of recent gene flow between wild and cultivated populations. Based on outlier detection methods, we identified 24 domestication-related SNPs, 13 related to cultivar diversification and eight under natural selection. Few of these SNPs fell within annotated loci, but the annotated domestication-related SNPs are highly expressed in flowers and pods. Our results contribute to the understanding of the domestication history of P. coccineus, and highlight how the genetic signatures of domestication can be substantially different between closely related species. PMID- 29187860 TI - Identification of Candidate Genes for Calcium and Magnesium Accumulation in Brassica napus L. by Association Genetics. AB - Calcium (Ca) and magnesium (Mg) are essential plant nutrients and vital for human and animal nutrition. Biofortification of crops has previously been suggested to alleviate widespread human Ca and Mg deficiencies. In this study, new candidate genes influencing the leaf accumulation of Ca and Mg were identified in young Brassica napus plants using associative transcriptomics of ionomics datasets. A total of 247 and 166 SNP markers were associated with leaf Ca and Mg concentration, respectively, after false discovery rate correction and removal of SNPs with low second allele frequency. Gene expression markers at similar positions were also associated with leaf Ca and Mg concentration, including loci on chromosomes A10 and C2, within which lie previously identified transporter genes ACA8 and MGT7. Further candidate genes were selected from seven loci and the mineral composition of whole Arabidopsis thaliana shoots were characterized from lines mutated in orthologous genes. Four and two mutant lines had reduced shoot Ca and Mg concentration, respectively, compared to wild type plants. Three of these mutations were found to have tissue specific effects; notably reduced silique Ca in all three such mutant lines. This knowledge could be applied in targeted breeding, with the possibility of increasing Ca and Mg in plant tissue for improving human and livestock nutrition. PMID- 29187859 TI - A Review of Biotechnological Artemisinin Production in Plants. AB - Malaria is still an eminent threat to major parts of the world population mainly in sub-Saharan Africa. Researchers around the world continuously seek novel solutions to either eliminate or treat the disease. Artemisinin, isolated from the Chinese medicinal herb Artemisia annua, is the active ingredient in artemisinin-based combination therapies used to treat the disease. However, naturally artemisinin is produced in small quantities, which leads to a shortage of global supply. Due to its complex structure, it is difficult chemically synthesize. Thus to date, A. annua remains as the main commercial source of artemisinin. Current advances in genetic and metabolic engineering drives to more diverse approaches and developments on improving in planta production of artemisinin, both in A. annua and in other plants. In this review, we describe efforts in bioengineering to obtain a higher production of artemisinin in A. annua and stable heterologous in planta systems. The current progress and advancements provides hope for significantly improved production in plants. PMID- 29187861 TI - Transcriptome-Wide Identification and Characterization of MYB Transcription Factor Genes in the Laticifer Cells of Hevea brasiliensis. AB - MYB transcription factors hold vital roles in the regulation of plant secondary metabolic pathways. Laticifers in rubber trees (Hevea brasiliensis) are of primary importance in natural rubber production because natural rubber is formed and stored within these structures. To understand the role of MYB transcription factors in the specialized cells, we identified 44 MYB genes (named HblMYB1 to HblMYB44) by using our previously obtained transcriptome database of rubber tree laticifer cells and the public rubber tree genome database. Expression profiles showed that five MYB genes were highly expressed in the laticifers. HblMYB19 and HblMYB44 were selected for further study. HblMYB19 and HblMYB44 bound the promoters of HbFDPS1, HbSRPP, and HRT1 in yeast. Furthermore, the transient overexpression of HblMYB19 and HblMYB44 in tobacco plants significantly increased the activity of the promoters of HbFDPS1, HbSRPP, and HRT1. Basing on this information, we proposed that HblMYB19 and HblMYB44 are the regulators of HbFDPS1, HbSRPP, and HRT1, which are involved in the biosynthesis pathway of natural rubber. PMID- 29187862 TI - Identifying Chloris Species from Cuban Citrus Orchards and Determining Their Glyphosate-Resistance Status. AB - The Chloris genus is a C4 photosynthetic species mainly distributed in tropical and subtropical regions. Populations of three Chloris species occurring in citrus orchards from central Cuba, under long history glyphosate-based weed management, were studied for glyphosate-resistant status by characterizing their herbicide resistance/tolerance mechanisms. Morphological and molecular analyses allowed these species to be identified as C. ciliata Sw., Chloris elata Desv., and Chloris barbata Sw. Based on the glyphosate rate that causes 50% mortality of the treated plants, glyphosate resistance (R) was confirmed only in C. elata, The R population was 6.1-fold more resistant compared to the susceptible (S) population. In addition, R plants of C. elata accumulated 4.6-fold less shikimate after glyphosate application than S plants. Meanwhile, populations of C. barbata and C. ciliata with or without glyphosate application histories showed similar LD50 values and shikimic acid accumulation rates, demonstrating that resistance to glyphosate have not evolved in these species. Plants of R and S populations of C. elata differed in 14C-glyphosate absorption and translocation. The R population exhibited 27.3-fold greater 5-enolpyruvyl shikimate-3-phosphate synthase (EPSPS) activity than the S population due to a target site mutation corresponding to a Pro-106-Ser substitution found in the EPSPS gene. These reports show the innate tolerance to glyphosate of C. barbata and C. ciliata, and confirm the resistance of C. elata to this herbicide, showing that both non target site and target-site mechanisms are involved in its resistance to glyphosate. This is the first case of herbicide resistance in Cuba.

AB - Traumatic brain injury (TBI) can cause persistent pathological alteration of neurons. This may lead to cognitive dysfunction, depression and increased susceptibility to life threatening diseases, such as epilepsy and Alzheimer's disease. To investigate the underlying genetic and molecular basis of TBI, we subjected w1118Drosophila melanogaster to mild closed head trauma and found that mitochondrial activity is reduced in the brains of these flies 24 h after inflicting trauma. To determine the transcriptomic changes after mild TBI, we collected fly heads 24 h after inflicting trauma, and performed RNA-seq analyses. Classification of alternative splicing changes showed selective retention (RI) of long introns (>81 bps), with a mean size of ~3,000 nucleotides. Some of the genes containing RI showed a significant reduction in transcript abundance and are involved in mitochondrial metabolism such as Isocitrate dehydrogenase (Idh), which makes alpha-KG, a co-factor needed for both DNA and histone demethylase enzymes. The long introns are enriched in CA-rich motifs known to bind to Smooth (Sm), a heterogeneous nuclear ribonucleoprotein L (hnRNP-L) class of splicing factor, which has been shown to interact with the H3K36 histone methyltransferase, SET2, and to be involved in intron retention in human cells. H3K36me3 is a histone mark that demarcates exons in genes by interacting with the mRNA splicing machinery. Mutating sm (sm4/Df) resulted in loss of both basal and induced levels of RI in many of the same long-intron containing genes. Reducing the levels of Kdm4A, the H3K36me3 histone demethylase, also resulted in loss of basal levels of RI in many of the same long-intron containing genes. Chromatin immunoprecipitation followed by deep sequencing (ChIP-seq) for H3K36me3 revealed increased levels of this histone modification in retained introns post-trauma at CA-rich motifs. Based on these results, we propose a model in which TBI temporarily decreases mitochondrial activity in the brain 24 h after inflicting trauma, which decreases alpha-KG levels, and increases H3K36me3 levels and intron retention of long introns by decreasing Kdm4A activity. The consequent reduction in mature mRNA levels in metabolism genes, such as Idh, further reduces alpha-KG levels in a negative feedback loop. We further propose that decreasing metabolism after TBI in such a manner is a protective mechanism that gives the brain time to repair cellular damage induced by TBI. PMID- 29187865 TI - A novel method of nicotine quantification in electronic cigarette liquids and aerosols. AB - The electronic cigarette (e-cigarette) has emerged as popular electronic nicotine delivery devices (ENDs). However, the general safety and validity of e-cigarettes for nicotine delivery efficacy are still not well understood. This study developed a new method for efficient measurement of nicotine levels in both the liquids (e-liquids) used in e-cigarettes and the aerosols generated from the e cigarettes. Protonation of the pyrrolidine nitrogen of nicotine molecules by addition of excess hydrochloric acid affords an aminium salt that is readily quantified by Fourier transform ion cyclotron mass spectrometry (FT-ICR-MS). The kinetics of nicotine protonation was studied using 1H NMR spectroscopy. Quantitative analyses of nicotine in commercial e-liquids and in the corresponding derived e-cigarette aerosols were carried out using direct infusion FT-ICR-MS. The 1H NMR study of nicotine protonation revealed a first order reaction and an activation energy of 30.05 kJ mol-1. The nicotine levels measured in the commercial e-liquids were within a wide and highly variable range of 2.94% to +25.20% around the manufacturer's stated values. The results indicated considerable differences between the measured levels and the advertised levels of nicotine in the e-liquids. The nicotine quantity measured in aerosols increased linearly both with nicotine level in e-liquids (same number of puffs) and with number of puffs (same e-liquids). These data show that quality control of e liquids and use characteristics are major variables in efficacy of nicotine delivery. PMID- 29187866 TI - Modification of proteolytic activity matrix analysis (PrAMA) to measure ADAM10 and ADAM17 sheddase activities in cell and tissue lysates. AB - Increases in expression of ADAM10 and ADAM17 genes and proteins have been evaluated, but not validated as cancer biomarkers. Specific enzyme activities better reflect enzyme cellular functions, and might be better biomarkers than enzyme genes or proteins. However, no high throughput assay is available to test this possibility. Recent studies have developed the high throughput real-time proteolytic activity matrix analysis (PrAMA) that integrates the enzymatic processing of multiple enzyme substrates with mathematical-modeling computation. The original PrAMA measures with significant accuracy the activities of individual metalloproteinases expressed on live cells. To make the biomarker assay usable in clinical practice, we modified PrAMA by testing enzymatic activities in cell and tissue lysates supplemented with broad-spectrum non-MP enzyme inhibitors, and by maximizing the assay specificity using systematic mathematical-modeling analyses. The modified PrAMA accurately measured the absence and decreases of ADAM10 sheddase activity (ADAM10sa) and ADAM17sa in ADAM10-/- and ADAM17-/- mouse embryonic fibroblasts (MEFs), and ADAM10- and ADAM17-siRNA transfected human cancer cells, respectively. It also measured the restoration and inhibition of ADAM10sa in ADAM10-cDNA-transfected ADAM10-/- MEFs and GI254023X-treated human cancer cell and tissue lysates, respectively. Additionally, the modified PrAMA simultaneously quantified with significant accuracy ADAM10sa and ADAM17sa in multiple human tumor specimens, and showed the essential characteristics of a robust high throughput multiplex assay that could be broadly used in biomarker studies. Selectively measuring specific enzyme activities, this new clinically applicable assay is potentially superior to the standard protein- and gene-expression assays that do not distinguish active and inactive enzyme forms. PMID- 29187867 TI - FAM13A as a Novel Hypoxia-Induced Gene in Non-Small Cell Lung Cancer. AB - : Several genome-wide association studies (GWASs), have identified that FAM13A and IREB2 loci are associated with lung cancer, but the mechanisms by which these genes contribute to lung diseases susceptibility, especially in hypoxia context, are unknown. Hypoxia has been identified as a major negative factor for tumor progression in clinical observation. It has been suggested, that lower oxygen tension, may modulate the IREB2 and FAM13A activity. However, the role of these genes in hypoxia response has not been explained. To precise the role of these genes in hypoxia response, we analyzed the FAM13A and IREB2 expression, in lung cancer cells in vitro and lung cancer tissue fragments cultured ex vivo. Three cell lines: non-small cell lung cancer (A549, CORL-105), human lung fibroblasts (HL) and 37 lung cancer tissue fragments were analyzed. The expression of IREB2, FAM13A and HIF1alpha after sustained 72 hours of hypoxia versus normal oxygen concentration were analyzed by TaqMan(r) Gene Expression Assays and Western Blot. The expression of FAM13A was significantly up-regulated by hypoxia in two lung cancer cell lines (A549, CORL-105, P<0.001), both at the level of protein and mRNA, and in lung cancer tissue fragments (P=0.0004). The IREB2 was down regulated after hypoxia in A549 cancer cells (P<0.001). CONCLUSIONS: We found that FAM13A overexpression in human lung cancer cell lines overlapped with hypoxia effect on lung cancer tissues. FAM13A is strongly induced by hypoxia and may be identified as a novel hypoxia-induced gene in non-small cell lung cancer. PMID- 29187868 TI - Cisplatin Nephrotoxicity Might Have a Sex Difference. An analysis Based on Women's Sex Hormone Changes. AB - Background: A sex difference in cisplatin-induced nephrotoxicity (CIN) has been reported in human and animal studies. We examined in humans whether it is associated with sex-hormone changes. Methods: In this retrospective nationwide cohort study, we used Taiwan's National Health Insurance Research Database (NHIRD) to identify patients with a history of malignancy and cisplatin treatment. Patients diagnosed with kidney disease before cisplatin treatment and those with sex-organ malignancies were excluded. A diagnosis of kidney disease within 90 days after the first administration of cisplatin was the study outcome. Risk factors were estimated using a Cox regression model. Subgroup analyses were performed based on different women's estrogen levels in phases of childbearing, perimenopause, and postmenopause. Results: A retrospective analysis of the records of 3973 men (mean age: 56.15 +/- 12.85 years) and 1154 women (mean age: 56.31 +/- 12.40 years) showed that 1468 (36.95%) men and 451 (39.08%) women had a new diagnosis of kidney disease. The risk factors were being > 55 years old, a high comorbidity score, and a history of aminoglycoside treatment. Only postmenopausal women had a significantly higher risk of kidney injury (hazard ratio: 1.28; 95% CI: 1.02-1.61) than did men. Conclusions: Perimenopausal women have a significantly higher risk of CIN than do men, which might be explained by women's higher levels of estrogen. Additional studies on the underlying mechanisms of the sex difference of CIN are needed. PMID- 29187869 TI - Fuzi Enhances Anti-Tumor Efficacy of Radiotherapy on Lung Cancer. AB - In traditional Chinese medicine, Fuzi is widely used as an antitumor agent or an adjuvant medication combined with radiotherapy and chemotherapy, but its mechanism remains unclear. In this study, we investigated anti-tumor and immunoregulation efficacy of Fuzi combined with radiotherapy in mice with Lewis lung cancer (LLC). We found that Fuzi combined with radiotherapy significantly inhibited the growth of LLC, promoted the apoptosis of cancer cells, and prolonged the survival of mice with LLC. Mechanistically, we found that Fuzi decreased the proportion of Treg cells, reduced serum levels of cytokines such as interleukin (IL)-10 and transforming growth factor (TGF)-beta, and downregulated the expression of programmed death ligand-1 in mice with LLC subjected to radiotherapy. This study suggests that Fuzi has immunomodulation function to act as radiosensitizer and improve radiotherapy against lung cancer. PMID- 29187870 TI - Ectopic Expression of Snail and Twist in Ph+ Leukemia Cells Upregulates CD44 Expression and Alters Their Differentiation Potential. AB - Philadelphia chromosome-positive (Ph+) leukemia is characterized by reciprocal translocation between chromosomes 9 and 22. The resultant BCR/ABL fusion protein displays constitutive tyrosine kinase activity, leading to the induction of aberrant proliferation and neoplastic transformation. The bone marrow (BM) microenvironment is tumor-promoting, and contributes to disease recurrence in Ph+ leukemia. Activity in the BM microenvironment is mediated by several cellular compartments, extracellular matrix, various soluble factors including transforming growth factor beta 1 (TGF-beta1), and the hypoxic conditions in the BM niche. TGF-beta1 is released during bone remodeling and plays a role in maintaining leukemic stem cells, as well as being implicated in the epithelial mesenchymal transition (EMT) process in most solid tumors. Although EMT is largely implicated in epithelial tumors, recent findings argue for an EMT-like process in leukemia as well. The surface receptor CD44 is involved in cell adhesion, cell migration, and homing of normal and malignant hematopoietic stem cells. Elevation of CD44 expression is considered a marker for a worse prognosis in most hematological malignancies. We explored the functions of Snail and Twist1 in Ph+ leukemia. We showed that ectopic expression of Snail and, to a lesser extent, Twist1, upregulates CD44 expression that is beta-catenin-dependent. Moreover, the presence of Snail or Twist1 partially blocked phorbol 12-myristate 13-acetate-induced megakaryocyte differentiation, while that of Twist significantly altered imatinib-induced erythroid differentiation. Thus EMT modulators affected proliferation, CD44 gene expression and differentiation ability of Ph+ leukemia cells. PMID- 29187871 TI - Local surgical excision versus endoscopic resection for rectal carcinoid: A meta analysis. AB - Purpose: To date, there is not enough evidence concerning the optimal treatment strategy for early rectal carcinoids, we conducted a meta-analysis in order to determine the feasible local treatment for these selected patients. Methods: We searched the studies from the PubMed, Cochrane database, Medline, Ovid, SpringerLink, PMC and Embase between January 2007 and April 2017. Studies of local surgical excision compared with endoscopic resection for rectal carcinoids less than 20mm without adverse features were included. Data were analyzed by using Stata SE 12.0. Results: Seven studies were included in this meta-analysis, with a total of 1056 patients. The data showed that local surgical excision was associated with higher complete resection rate than that of endoscopic resection (OR 5.837, 95%CI 2.048 to 16.632, P=0.001) but consuming longer procedural time (SMD 1.757, 95% CI 1.263 to 2.251, P=0.000). Additionally, incidences of recurrence and en bloc resection rate were comparable between two kinds of resections. The difference of post-operative complications remained unclear. Conclusions: For rectal carcinoids sized 20mm or smaller without adverse features, endoscopic resection might be an efficient treatment, which achieved a comparable oncological safety as local surgical excision. PMID- 29187872 TI - Tumoral ANXA1 Is a Predictive Marker for Sunitinib Treatment of Renal Cancer Patients. AB - Background and aims: There is no established predictive marker for the treatment of renal cancer. Metastatic renal cell carcinoma (mRCC) patients are often treated with sunitinib, a tyrosine kinase inhibitor. Sunitinibs anti-cancer effect is at least partly mediated through interfering with angiogenesis. Our aim with the current study was to assess annexin A1 (ANXA1), which stimulates angiogenesis, as a predictive marker for sunitinib therapy in mRCC patients. Since previous studies have indicated a predictive potential for cubilin, we also investigated the predictivity of ANXA1 combined with cubilin. Methods: ANXA1 expression was analysed in tumor tissue from a cohort of patients with advanced RCC (n=139) using immunohistochemistry. Ninety-nine of the patients were treated with sunitinib in the first or second-line setting. Twenty-two of these were censored because of toxicity leading to the termination of treatment and the remaining (n=77) were selected for the present study. Results: Twenty-five (32%) out of seventy-seven of the tumors lacked ANXA1 in the cytoplasm. On statistical analyses using Kaplan-Meier method, aNXA1 negative tumors were significantly associated with a longer treatment benefit in terms of progression free survival (PFS). Overall survival was also significantly better for patients with ANXA1 negative tumors. The combined ANXA1 positive and cubilin negative expression could more accurately than ANXA1 alone define the group not benefitting from treatment. Conclusions: Our results indicate that cytoplasmic expression of ANXA1 is a negative predictive marker for sunitinib therapy in mRCC patients. A possible explanation for this finding is that sunitinibs anti-angiogenic effect cannot overcome the pro-angiogenic drive from many ANXA1 proteins. PMID- 29187873 TI - Post-Resection Exhaustion of Intra-Platelet Serotonin: Also an Indicator of Early Hepatocellular Carcinoma Recurrence? AB - Purpose: Serotonin (5-hydroxytryptamine, 5-HT) is well known for its growth stimulatory effect on several types of carcinoma and tumor cells. Since a large portion of 5-HT is stored and transported by platelets, the aim of this study was to assess the influence of platelet-sequestered 5-HT on post-resection hepatocellular carcinoma (HCC) recurrence. Methods: This pilot study was conducted in a cohort of forty patients diagnosed with HCC undergoing partial hepatectomy. 5-HT levels in serum, plasma and intra-platelet (IP) were monitored preoperatively and four weeks after liver resection. The patients were followed every three months after the surgery. Results: Follow-up was standardized to a fixed length of time. Fifteen patients (37.5%) developed HCC recurrence during 18 months follow-up. Patients with recurrence had significantly reduced serum and IP 5-HT levels at four weeks of liver resection (P = 0.003 and P = 0.014 respectively). Accordingly, in the Cox regression hazard model, serum and IP 5-HT were able to independently predict the recurrence (hazard ratio = 0.1, 95% confidence interval = 0.01 - 0.75 and hazard ratio = 0.1, 95% confidence interval = 0.01 - 0.89 respectively). The optimal cut-off value of 42.77 ng/ml for serum [area under the curve (AUC): 0.78, P = 0.003] and 0.3117 ng per 106 platelets (AUC: 0.733, P = 0.015), on receiver operating characteristic (ROC) curve corresponded to maximum sensitivity and specificity of prediction. The disease free interval was significantly worse in patients with low serum and IP 5-HT (P = 0.001 and P = 0.029 respectively). Conclusion: IP 5-HT monitored during early follow-up, after liver resection may represent a useful marker of early HCC recurrence. PMID- 29187874 TI - Albumin and Fibrinogen Combined Prognostic Grade Predicts Prognosis of Patients with Prostate Cancer. AB - Background: The nutritional status and systemic inflammation are thought to be associated with outcome in multiple types of cancer. The objective of this study was to determine the prognostic value of pretreatment albumin and fibrinogen combined prognostic grade (AFPG) in prostate cancer (PCa). Methods: 462 prostate cancer patients who had undergone androgen deprivation therapy (ADT) as first line therapy at four cencters were retrospectively analyzed. The serum albumin levels and plasma fibrinogen levels were measured at the time of diagnosis. The AFPG was calculated according to albumin and fibrinogen levels dichotomized by optimal cut-off values or clinical reference values. Univariate and multivariate cox regression analyses were performed to determine the associations of AFPG with progression-free survival (PFS), cancer-specific survival (CSS) and overall survival (OS). Prognostic accuracy was evaluated with the Harrell concordance index. Results: Multivariate analyses identified AFPG as an independent prognostic indicator for PFS, CSS and OS (each p < 0.01). According to optimal cut-off values, the addition of AFPG to the final models improved predictive accuracy for PFS, CSS and OS compared with the clinicopathological base models, which included Gleason score and incidence of metastasis. Moreover, AFPG according to optimal cut-off values was a better prognostic predictor than albumin levels alone or fibrinogen levels alone or AFPG according to clinical reference values. Conclusion: Decreased AFPG could predict a significantly poor prognosis in patients with PCa. Thus, we recommend adding AFPG according to optimal cut-off values to traditional prognostic model to improve the predictive accuracy. PMID- 29187875 TI - Prognostic Effect of Albumin-to-Globulin Ratio in Patients with solid tumors: A Systematic Review and Meta-analysis. AB - Background: Albumin and globulin are main components of serum protein. The level of albumin and globulin partially represents the nutrition status and immune system. Albumin-to-globulin ratio (AGR) has been reported as a prognostic factor in various cancers. We therefore performed a meta-analysis to elucidate the prognosis effect of AGR on survival outcomes in solid tumors. Method: Six electronic database were searched for the relevant articles that assessing the prognostic value of pre-treatment AGR in solid tumor patients. The primary outcome was overall survival (OS) and the secondary outcomes were cancer-specific survival (CSS), disease-free survival (DFS) and disease-metastasis-free survival (DMFS). The time-to-event outcomes were summarized in hazard ratio (HR) and 95% confidence interval (CI). Result: A total of 13890 solid tumor patients in 24 studies were included. The AGR higher than the cut-off values ranging from 1.15 1.75 was related to better OS (HR=0.58, 95%CI 0.537-0.626, p<0.0001), CSS (HR=0.287, 95%CI 0.187-0.438, p<0.0001), DFS (HR=0.792, 95%CI 0.715-0.878, p<0.0001) and DMFS (HR=0.595, 95%CI 0.447-0.792, p<0.0001). According to the cut off values, subgroup analysis showed that AGR had significant prognostic effect on OS in each cut-off intervals (<=1.20, 1.20-1.40 and >=1.40). Conclusion: Pre treatment AGR is an effective prognostic factor and high AGR represents an ideal clinical outcome in the solid tumor patients. PMID- 29187876 TI - Heteroplasmy and Copy Number Variations of Mitochondria in 88 Hepatocellular Carcinoma Individuals. AB - Hepatocellular carcinoma (HCC) is the third leading cause of cancer mortality worldwide. In this study, we had analysed the copy number variations and heteroplasmic mutations of mitochondria (MT) in 88 HCC individuals. The average copy number of MT genome in normal samples was significantly greater than that in tumor samples. Overall, the number of heteroplasmic mutations in 88 tumor and their matched normal samples were 241 and 173, respectively. There was higher positive ratio of heteroplasmic mutations in tumor samples (86%) than normal samples (73%). Worthwhile mention, ND1 gene harbored greater mutation frequency and more nonsynonymous mutations in tumor samples. Interestingly, 202 tumor specific heteroplasmic mutations were detected. Moreover, ND1, ND3, ND4, ND5 and ND6 genes had higher ratio of nonsynonymous versus synonymous mutations in tumor specific heteroplasmic mutations. It might suggest that the disorder of NADH dehydrogenase (complex I) resulted by heteroplasmic mutations may have close relation with tumorigenesis of hepatocellular carcinoma. This study provided theoretical basis for further understanding mechanism of tumorigenesis from the perspective of mitochondrial heteroplasmic mutations. PMID- 29187877 TI - Overexpression of CKAP4 is Associated with Poor Prognosis in Clear Cell Renal Cell Carcinoma and Functions via Cyclin B Signaling. AB - Aim: We aimed to study the role of CKAP4 in clear cell renal cell carcinoma (ccRCC), which is not reported previously. Method: In silico exploration and validation using immunohistochemistry in ccRCC samples were used to identify the impact of CKAP4 expression on clinicopathological parameters. In vitro and in vivo studies were carried out to recapitulate the role of CKAP4 in ccRCC cell lines and animal models. Results: Overexpression of CKAP4 occurred in 5% of ccRCC patients, who had significantly worsened prognosis. Increased CKAP4 expression was significantly associated with TNM staging and Fuhrman grade. Pathway analysis for genes coexpressed with CKAP4 in ccRCC unanimously revealed significant cell cycle progression at G2/M phase. Expressions of CCNB1 and CCNB2 were correlated with CKAP4 expression. Genetic upregulation of CKAP4 significantly increased proliferation, cell invasion and migration in ccRCC cell lines, and vice versa for CKAP4 silencing. CKAP4 silencing also significantly increased cell population at G2/M phase, while not influencing cell apoptosis. Silencing or upregulation of CKAP4 resulted in decreased or increased CCNB1/2 expressions, respectively. CCNB1/CDK1 inhibitor significantly inhibited colony formation ability and in vivo tumor growth of RCC cells with CKAP4 overexpression. Conclusion: Upregulation of CKAP4 was associated with worsened characteristics of ccRCC. CKAP4 was related with CCNB signaling in ccRCC, which supported a role for CCNB/CDK inhibitor for ccRCC with such genotype. PMID- 29187878 TI - UHRF1 is an Independent Prognostic Factor and a Potential Therapeutic Target of Esophageal Squamous Cell Carcinoma. AB - Purpose: Ubiquitin-like with plant homeodomain and ring-finger domains 1 (UHRF1) plays an essential role in DNA methylation, and the overexpression of UHRF1 is associated with poor prognosis in various cancers. Esophageal squamous cell carcinoma (ESCC) accounts for approximately 90% of esophageal cancer cases in China, but the five-year survival rate for patients is less than 10% due to limited clinical approaches for early diagnosis and treatment. The present research aimed to investigate the expression of UHRF1 in ESCC and its biological role in ESCC development. Methods: UHRF1 expression in ESCC and normal esophageal tissues was examined using immunohistochemical staining, followed by analysis of the correlation between UHRF1 expression and clinical features. In addition, the effects of lentivirus-mediated RNA interference of UHRF1 on global DNA methylation, cell proliferation, cell cycle progression and apoptosis and were investigated in ESCC cells. Results: UHRF1 was overexpressed in ESCC tissues and was an independent prognostic factor for ESCC patients. In ESCC cells, knockdown of UHRF1 caused global DNA hypomethylation, inhibited cell proliferation and induced apoptosis. Furthermore, UHRF1 depletion induced cell cycle arrest at the G2/M phase, accompanied by activation of Wee1 and DNA damage response pathway. Conclusions: Our findings identify UHRF1 as a promising prognostic marker for ESCC and suggest that UHRF1 may be a potential therapy target for ESCC patients with elevated UHRF1 expression. PMID- 29187880 TI - The PARP-1 inhibitor Olaparib suppresses BRCA1 protein levels, increases apoptosis and causes radiation hypersensitivity in BRCA1+/- lymphoblastoid cells. AB - The use of polyADPribose polymerase inhibitors in cancer treatment provides a unique opportunity to target DNA repair processes in cancer cells while leaving normal tissue intact. The PARP-1 enzyme repairs DNA single strand breaks (SSB). Therefore PARP-1 inhibition in BRCA1 negative cancers results in the formation of cytotoxic DNA double strand breaks (DSB) causing synthetic lethality. The use of PARP1 inhibitors is gaining momentum in the treatment of a variety of tumours with BRCA1 involvement including breast, ovarian, pancreatic and prostate cancer. Our previous work showed that the PARP-1 inhibitor Olaparib causes both hypersensitivity of BRCA1+/- cells following exposure to gamma radiation due to the persistence of DNA strand breaks in cells, measured by the DNA damage biomarker gamma-H2AX. Therefore dual treatment of cancers with radiotherapy and PARP1 inhibition may lead to cases of increased normal tissue toxicity in cancer patients. In this study we exposed two normal lymphoblastoid cell lines and three heterozygous BRCA1 lymphoblastoid cell lines to the PARP-1 inhibitor Olaparib and gamma radiation and after measured BRCA1 protein expression and apoptosis levels following treatment. BRCA1 protein foci analysis was performed on cells exposed to 2 Gy radiation in the presence or absence of 5 MUM Olaparib. Using immunofluorescence and imaging flow cytometry, foci were measured in untreated cells and at 0.5, 3, 5 and 24 hours post-irradiation. Exposing normal and BRCA1+/ cells to Olaparib followed by gamma radiation results in a dramatic change in BRCA1 protein foci expression, with a significant reduction in BRCA1 protein expression observed in the heterozygote cells, together with an increase in apoptosis levels in these cells. In conclusion, combining PARP1 inhibitors with radiotherapy in treating of BRCA1-related cancers has clinical relevance, however this study and our previous publications serve to highlight the potential problems of increased side effects in these scenarios. PMID- 29187879 TI - Aberrant Expression of the Long Non-coding RNA GHRLOS and Its Prognostic Significance in Patients with Colorectal Cancer. AB - Long non-coding RNAs (lncRNAs), which have emerged as important regulatory RNA molecules that have been implicated in carcinogenesis and cancer progression, may also serve as novel potential biomarkers for cancer diagnosis and prognosis. Our previous analysis has identified the lncRNA GHRLOS, the ghrelin antisense strand non-coding RNA gene, as one of the hub genes in the co-expression network of differentially expressed lncRNAs/mRNAs in colorectal cancer (CRC). Here, we further evaluate the expression of GHRLOS in CRC and explore its clinical significance. The expression of GHRLOS in 366 pairs of CRC and adjacent non cancerous tissues was detected by quantitative RT-PCR assays. The results showed that the expression level of GHRLOS was significantly lower in CRC tissues than in matched non-cancerous tissues (P < 0.001). Decreased GHRLOS expression was observed in 54.4% (199/366) of cases, and was significantly correlated with the occurrence of lymph node metastasis (P = 0.033) and distant metastasis (P = 0.005). A Kaplan-Meier analysis demonstrated that decreased GHRLOS expression contributed to poor disease-free survival (log-rank test, P < 0.001) and overall survival (log-rank test, P < 0.001). Moreover, a multivariate Cox regression analysis revealed the decreased expression of GHRLOS as an independent prognostic marker of poor outcomes [disease-free survival: hazard ratio (HR) = 2.02, 95% confidence interval (CI) = 1.42-3.88; overall survival: HR = 1.96, 95% CI = 1.34 2.86] in CRC patients. In conclusion, our data suggest that the lncRNA GHRLOS might serve as a candidate biomarker of tumor metastasis and a prognostic indicator in CRC. PMID- 29187881 TI - Hazard rate of tumor recurrence over time in patients with colon cancer: implications for postoperative surveillance from three Japanese Foundation for Multidisciplinary Treatment of Cancer (JFMC) clinical trials. AB - Purpose: Reliable risk estimates of recurrence are necessary to establish optimal postoperative surveillance strategies. The purpose of the present study was to clarify changes in the hazard rate (HR) for tumor recurrence over time in Japanese patients with colon cancer. Methods: Data for 3984 patients from three clinical trials evaluating the benefit of adjuvant chemotherapy for colon cancer were analyzed. Estimated HRs were plotted over time for the entire cohort, as well as for node-positive and node-negative patients separately. The changes in risk were further analyzed according to eight clinical variables, and factors predictive of early (<3 years) and late (>3 years) recurrence were explored using Cox's regression analysis. Results: In node-positive patients, there was a prominent HR peak 0.6 years after surgery, whereas HR remained at consistently low levels in node-negative patients. In node-positive patients, HR decreased steadily until 3 years, after which the decline in HR plateaued. Those with T4 tumors had a prominent HR peak around 1 year, including node-negative patients. The HR for T1/T2 Stage III colon cancers showed a similar pattern as that for T1 T3 node-negative colon cancers. Cox regression analysis revealed that a lack of adjuvant chemotherapy, positive node status, T3/T4 factors, and male gender predict early recurrence, whereas patients with lymph node metastasis, T4 tumors, and a lesser extent of lymph node removal have a higher risk of recurrence 3-4 years after surgery (P<0.05). Conclusion: The present study supports the concept of intensive surveillance during the first 3 years after curative resection. However, a reduction in surveillance intensity may be acceptable for patients with T3 Stage II and T1/T2 Stage III colon cancer. PMID- 29187882 TI - Proteomic analysis of lung metastases in a murine breast cancer model reveals divergent influence of CTSB and CTSL overexpression. AB - Studies in the MMTV-PyMT (PyMT) breast cancer mouse model have shown a strong influence of the lysosomal cysteine cathepsins B or L on lung metastasis formation. Transgenic expression of human CTSB (tgCTSB) or CTSL (tgCTSL) both led to similar metastatic phenotypes with increased metastatic burden in the PyMT mice. However, recent studies in other tumor models proved marked differences in effects of either cathepsin on the proteome composition. We sought to analyze and compare proteome changes in the metastatic proteome of PyMT mice expressing either tgCTSB or tgCTSL to evaluate similarities and differences in those models. Performing an explorative, quantitative proteome comparison based on LC-MS/MS, we identified up to 3,000 proteins from murine lung metastases in three independent biological replicates per genotype. In both cases, when compared to wild-type (WT) mice, we noticed a pronounced impact of transgene cathepsin expression on the metastasis proteome. Highlights include increased moesin, integrin beta 1 and vinexin levels in the tgCTSB dataset and increased saposin and granulin levels in the tgCTSL dataset. Importantly, non-supervised hierarchical clustering clearly separated tgCTSB vs. tgCTSL induced proteome changes. In summary, tgCTSB and tgCTSL both display a strong and distinct impact on proteome composition of lung macrometastases in the PyMT model. Our observations suggest that they impact malignant behavior in distinct ways, thus further emphasizing interest into their tumor-contextual functionality. PMID- 29187884 TI - A Single Nucleotide Polymorphism in HPGD Gene Is Associated with Prostate Cancer Risk. AB - Introduction: The HPGD gene was associated with some cancers, such as colorectal, breast, prostate, and bladder. However, detailed role of 15-hydroxyprostaglandin dehydrogenase (HPGD) gene remain unclear in prostate cancer. The study was to investigate the correlation between rs8752 that located in the 3'untranslated region (UTR) of the 15-hydroxyprostaglandin dehydrogenase (HPGD) gene and prostate cancer (PCa) risk. Materials and Methods: 109 patients from the First Affiliate Hospital of Soochow University were recruited. According to the results of pathologic diagnosis, all patients were divided into two groups (prostate cancer and benign prostatic hyperplasia). The single-nucleotide polymorphism (SNP) rs8752 was genotyped in all samples by direct sequencing. Results: 54 prostate cancer and 55 BPH patients were included with a median age of 70.41 and 67.62 years, respectively. No statistically significant difference between two groups in patient criteria. The frequency of the GG homozygote and AG+GG genotype were 37.74% and 62.26% in 54 prostate cancer samples, while in 55BPH patients, values were 62.50% and 37.50%. Compared with the GG genotype, the combined GA+AA genotypes had a significantly higher risk of prostate cancer (OR = 2.750; 95% CI: 1.266-5.971, p = 0.011). Furthermore, the risk effect was obtained in subgroups of PCa patient group, the AA+AG genotypes significantly associated with the higher Gleason score samples (AA+AG vs GG: OR = 3.50, 95%CI = 1.106-11.072, p = 0.033) and the risk of pathological stage (AA+AG vs GG: OR = 4.00, 95%CI = 1.253 12.767, p = 0.019). Conclusions: rs8752 in the 3'untranslated region (UTR) of the 15-hydroxyprostaglandin dehydrogenase (HPGD) gene was found to be responsible for the susceptibility to prostate cancer in Chinese individuals. PMID- 29187883 TI - Programmed cell death ligand 1 protein levels predicted survival of non-small cell lung cancer. AB - Objective: To investigate the relationship between programmed death ligand 1 (PD L1) expression using 5%, 25%, 50% cutoffs in tumor cells (TC) and postsurgical survival in non-small-cell lung cancer (NSCLC) patients. For samples with tumor infiltrating lymphocytes (TIL), correlation between PD-L1 expression in TIL using 1% cutoff and postsurgical survival was also evaluated. Methods: Primary NSCLC tumor surgical samples staging I to IIIA of 126 patients who underwent surgical procedures from September 2009 to August 2012 in Shanghai Chest Hospital, Shanghai Jiao Tong University were retrospectively included. PD-L1 protein expression was detected by immunohistochemistry (IHC) assays. A rabbit anti-human PD-L1 (E1L3N) monoclonal antibody (1:300, CST#13684, Cell Signaling Technology) was used for PD-L1 IHC staining. PD-L1 expression was evaluated both on TC and TIL. Univariate and multivariate analyses for postsurgical survival were done using Kaplan-Meier and Cox regression model, respectively. Results: The median postsurgical survival for all patients was 44.1 months [95% confidence interval (CI): 33.9-70.0 months). The median postsurgical survival for PD-L1 expression percentage 0, 1-50% and >=50% were 51.9 months (95%CI: 33.9-70.0 months), 33.2 months (95%CI: 20.8-45.6 months) and 14.7 months (95%CI: 1.9-27.6 months), respectively (P = 0.002). Clinical stage and PD-L1 expression in TC (25% cutoff or 50% cutoff values) were found to be independent predictors for longer postsurgical survival in all cohort. Ninety (71.4%) of the 126 samples were identified to concurrent TIL. The median postsurgical survival time was 39.6 months (95% CI: 31.8-47.4 months) in patients with TIL. PD-L1 expression in TC (25% cutoff or 50% cutoff values) was found to be the independent predictor for longer postsurgical survival time in patients with TIL. Conclusion: PD-L1 negative expression in TC at 25% or 50% cutoff values was the independent predictor for longer postsurgical survival time in both NSCLC samples and NSCLC samples with TIL. For patients with PD-L1 high expression at 25% or 50% cutoff values, PD-L1 blocking may be considered. PMID- 29187885 TI - Huaier Restrains Proliferative and Migratory Potential of Hepatocellular Carcinoma Cells Partially Through Decreased Yes-Associated Protein 1. AB - In China, Trametes robiniophila Murr (Huaier), a traditional Chinese herbal medicine, has been widely used in adjuvant therapies of hepatocellular carcinoma (HCC). However, the molecular mechanisms have not been fully understood. The aims of this study are to investigate the functions and mechanisms of Huaier on inhibiting proliferation and migration of HCC cells. Firstly, cell counting kit-8 (CCK-8) and colony formation shown Huaier inhibited proliferation of HCC Bel 7404, Bel-7402 and SMMC-7721 cells in a dose-dependent manner, and this inhibition might be due to Huaier decreased the expressions of the proliferating cell nuclear antigen (PCNA), the nuclear proliferation related antigen (Ki-67) and CyclinD1 detected by western blotting analysis. Notably, we also found Huaier treatment did not cause any cytotoxicity to normal human hepatocyte L-02 cells. Next, we found Huaier dose-dependently decreased Bcl-2 expression and increased Bax expression in Bel-7404 cells. The activities of cleaved caspase substrates had also been enhanced after Huaier treatment, suggesting Huaier treatment could induce HCC cell apoptosis. Then, the inhibitory effects of Huaier on migration of Bel-7404, Bel-7402 and SMMC-7721 cells via inhibiting Epithelial mesenchymal transition (EMT) had also been proved. Moreover, we confirmed yes-associated protein 1 (YAP1) was up-regulated in HCC cells and tissues, and overexpression of YAP1 promoted HCC cell proliferation and migration. Then, western blot and immunefluorescence shown Huaier had the inhibitory effects on YAP1 in HCC cells. On the other hand, human liver cancer tissue microarray (TMA) shown YAP1 expression was closely to clinic. Our study also confirmed Huaier had the inhibitory effects on YAP1 in xenograft mice models, it could be because Huaier treatment translocated YAP1 from nucleus to cytoplasm, and further promoted phosphorylation of YAP1 to be degraded by ubiquitination. Hence, we conclude that Huaier may restrain the proliferation and migration of HCC cells via down regulation of YAP1. In summary, our study reveals the potential mechanisms of Huaier on inhibiting proliferation and migration of HCC cells. Importantly, for the first time, we found that Huaier can inhibit YAP1 expression in this anti tumor process. We believe this finding is beneficial for the clinical applications of Huaier and the targeted therapies for HCC. PMID- 29187886 TI - Prognostic value of tumor-infiltrating Foxp3+ regulatory T cells in patients with breast cancer: a meta-analysis. AB - PURPOSE: The prognostic value of tumor-infiltrating Foxp3+ regulatory T cells (Tregs) in breast cancer remains controversial. Therefore, we performed this meta analysis to determine the impact of Foxp3+ Tregs infiltration on survival outcomes. METHODS: Relevant literature was retrieved from Pubmed, Web of science and Cocohrane until May 30, 2016. Meta-analysis was performed using hazard ratios (HRs), odds ratio (OR) and 95 % confidence intervals (CI) as effect measures. RESULTS: Fourteen studies (10,259 patients) were included. Meta-analysis showed that high Foxp3+ Tregs infiltration was correlated with high histological grade (OR= 2.96, 95%CI [2.03-4.31]), estrogen receptor (ER) negativity (OR= 0.38, 95%CI [0.23-0.60]), human epidermal growth factor receptor type 2 (HER2) positivity (OR=2.43, 95%CI [1.69-3.51]). The detection of FOXP3+ Tregs was significantly associated with recurrence-free survival (RFS) of patients (HR = 1.58, 95 % CI [1.03-2.44]). CONCLUSION: Our meta-analysis suggests that high Foxp3+ Tregs infiltration is associated with poor RFS in breast cancer patients and predicts histological grade, estrogen receptor and HER-2 status. PMID- 29187887 TI - Long Non-coding RNA XIST Promotes Glioma Tumorigenicity and Angiogenesis by Acting as a Molecular Sponge of miR-429. AB - Glioma is a worldwide malignancy, which displays significantly active metastasis and angiogenesis. Interaction between long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) has been shown to play crucial role in regulating tumor properties. However, the potential of lncRNA X-inactive specific transcript (XIST) to function as a miRNA regulator and its relevance in glioma tumorigenicity and angiogenesis have so far remained unclear. Expression analysis of lncRNA XIST in glioma cells revealed its significant up-regulation. Interestingly, silencing of XIST repressed both metastatic and pro-angiogenic ability in vitro as well as in vivo. Subsequent studies revealed that lncRNA XIST expression inversely correlated with miR-429 expression in glioma cells; miR-429 modulated XIST expression by directly targeting the XIST gene sequence. In addition, miR-429 inhibitor restored metastatic and pro-angiogenic ability of gliomas abolished by silencing XIST. Our data provide insight into the key roles of the lncRNA-miRNA functional network in gliomas, which can aid in developing new therapeutic strategies for gliomas through clinical trials. PMID- 29187888 TI - Advantage of PET/CT in Target Delineation of MRI-negative Cervical Lymph Nodes In Intensity-Modulated Radiation Therapy Planning for Nasopharyngeal Carcinoma. AB - Introduction: In intensity-modulated radiation therapy (IMRT) planning for nasopharyngeal carcinoma (NPC), cervical lymph nodes (CLNs) that appear negative on magnetic resonance imaging (MRI) scans can be difficult to target. The purpose of this study was to assess the advantage of 18F-fluorodeoxyglucose positron emission tomography with computed tomography (18F-FDG PET/CT) for distinguishing MRI-negative CLNs and the effect of 18F-FDG PET/CT on diagnosis, target delineation, and dose prescription in IMRT planning for NPC. Methods: Thirty-five NPC patients with 37 MRI-negative CLNs underwent 18F-FDG PET/CT imaging before treatment. Ultrasonography-guided fine-needle aspiration cytology (USgFNAC) was performed to examine the pathology of CLNs. The 18F-FDG PET/CT and cytopathological results were compared, and the diagnostic accuracy of 18F-FDG PET/CT was calculated. The cytopathologically confirmed CLNs were delineated and treated as the gross tumor volume of lymph nodes (denoted as GTVnd). Results: Nineteen of the 37 MRI-negative CLNs were positive on 18F-FDG PET/CT, and metastasis was confirmed by USgFNAC in 16 CLNs. Of the remaining 18 18F-FDG PET/CT-negative lymph nodes, metastasis was confirmed in one. The diagnostic accuracy, sensitivity, and specificity of 18F-FDG PET/CT were 89.2%, 94.1%, and 85.0%, respectively. The positive and negative predictive values were 84.2% and 94.4%, respectively. With a median follow-up of 48.3 months, no relapse was observed among the 18F-FDG PET/CT-positive CLNs with metastasis confirmed by USgFNAC and treated as GTVnd. Conclusion:18F-FDG PET/CT had high accuracy, sensitivity, and specificity for distinguishing MRI-negative CLNs. 18F-FDG PET/CT positive CLNs could reasonably be categorized as high-risk clinical tumor volume in IMRT planning for NPC. PMID- 29187889 TI - T-cell Acute Lymphoblastic Leukemia Cells Display Activation of Different Survival Pathways. AB - T-cell acute lymphoblastic leukemia (T-ALL) is a disease of the blood affecting T lymphocytes. Although notable improvements have been achieved in T-ALL treatment, half of the adult T-ALL patients still experience treatment failure. In order to develop a targeted therapy, we need a better understanding of T-ALL pathogenesis. In this study, we used patient-derived cell lines which display resistance to glucocorticoids. We observed that different cell lines are dependent on different survival signaling pathways. Aberrant activation of AKT, p38, S6K or ERK signaling was not found to the same degree in all cell lines studied. To understand the molecular differences in T-ALL cells, we compared gene expression and somatic mutations. Gene set enrichment analysis showed enrichment of the mTORC1, MAPK or TGF-beta signaling pathways. Loss-of-function mutations in the TP53 and FBXW7 genes were identified in all cell lines investigated. Thus, we suggest that T-ALL cells from different patients are addicted to different mutations and thereby to different signaling pathways. Therefore, understanding the enrichment of molecular pathways for each individual patient will provide us with a more precise and specific treatment plan. PMID- 29187890 TI - Decreased KPNB1 Expression is Induced by PLK1 Inhibition and Leads to Apoptosis in Lung Adenocarcinoma. AB - Lung cancer is a major cause of death worldwide, with lung adenocarcinoma being the most frequently diagnosed subtype in Japan. Finding the target of an anticancer drug can improve lung adenocarcinoma treatments. Polo-like kinase 1 (PLK1) is an essential mitotic kinase in mitotic progression, and PLK1 inhibition induces cell cycle arrest and apoptosis in tumor cells. In addition, a variety of PLK1 inhibitors have been identified for cancer treatments. In this study, we looked for the target gene of the anticancer drug that has synergy with PLK1 inhibitors. We identified karyopherin beta 1 (KPNB1) as a possible target for lung adenocarcinoma treatment. We found that PLK1 inhibition decreased KPNB1 expression in lung adenocarcinoma cells and KPNB1 depletion inhibited cell proliferation via apoptosis. The same apoptosis signaling pathway may be activated because the expression of common apoptosis-related genes was decreased by PLK1 and KPNB1 silencing; however, the time course of cell growth inhibition was somewhat different. Cell cycle analysis showed that KPNB1 depletion increased the proportion of cells at the G0/G1 phase, although cells also accumulated at the G2/M phase in PLK1-depleted cells. Our findings suggest that decreased KPNB1 expression may be associated with the apoptosis induced by PLK1 inhibition. PMID- 29187892 TI - Defining Radiation-Induced Hepatic Toxicity in Hepatocellular Carcinoma Patients Treated with Stereotactic Body Radiotherapy. AB - The definition and criteria of radiation-induced hepatic toxicity (RIHT) in hepatocellular carcinoma patients vary among studies. Therefore, the reported rates of RIHT differ among studies, and this causes confusion. In this study, we evaluated RIHT using several laboratory and clinical parameters, and analyzed which criterion is more correlated with RT and survival. Forty-five HCC patients treated with stereotactic body radiotherapy were included for the analysis. All patients had unresectable HCC and Child-Pugh (CP) class A or B baseline liver function. A median total dose of 45 Gy was delivered by CyberKnife in 3 fractions. For individual laboratory parameter, >= grade 2 toxicity development of bilirubin, albumin, or prothrombin time by Common Terminology Criteria of Adverse Effects (CTCAE) was correlated with mean liver dose and survival. However, serum transaminases had no correlation with liver mean dose and survival, and were rather affected by other local treatments. Compared to the CTCAE, the increase in the CP score of 2 points or more was better correlated with liver failure and overall survival, and it was not affected by other local treatments or tumor progression. We concluded RIHT was better defined by the change in the CP score rather than the CTCAE in patients treated by stereotactic body radiotherapy for HCC. PMID- 29187893 TI - Detection of Treatment Success after Photodynamic Therapy Using Dynamic Contrast Enhanced Magnetic Resonance Imaging. AB - Early evaluation of response to therapy is crucial for selecting the optimal therapeutic follow-up strategy for cancer patients. PDT is a photochemistry-based treatment modality that induces tumor tissue damage by cytotoxic oxygen radicals, generated by a pre-injected photosensitive drug upon light irradiation of tumor tissue. Vascular shutdown is an important mechanism of tumor destruction for most PDT protocols. In this study, we assessed the suitability of Dynamic Contrast Enhanced Magnetic Resonance Imaging (DCE-MRI) to evaluate treatment efficacy within a day after photodynamic therapy (PDT), using the tumor vascular response as a biomarker for treatment success. Methods: DCE-MRI at 7 T was used to measure the micro-vascular status of subcutaneous colon carcinoma tumors before, right after, and 24 h after PDT in mice. Maps of the area under the curve (AUC) of the contrast agent concentration were calculated from the DCE-MRI data. Besides, tracer kinetic parameters including Ktrans were calculated using the standard Tofts-Kermode model. Viability of tumor tissue at 24 h after PDT was assessed by histological analysis. Results: PDT led to drastic decreases in AUC and Ktrans or complete loss of enhancement immediately after treatment, indicating a vascular shutdown in treated tumor regions. Histological analysis demonstrated that the treatment induced extensive necrosis in the tumors. For PDT-treated tumors, the viable tumor fraction showed a strong correlation (rho >= 0.85) with the tumor fraction with Ktrans > 0.05 min-1 right after PDT. The viable tumor fraction also correlated strongly with the enhanced fraction, the average Ktrans , and the fraction with Ktrans > 0.05 min-1 at 24 h after PDT. Images of the viability stained tumor sections were registered to the DCE-MRI data, demonstrating a good spatial agreement between regions with Ktrans > 0.05 min-1 and viable tissue regions. Finally, 3D post-treatment viability detection maps were constructed for the tumors of three mice by applying a threshold (0.05 min-1) to Ktrans at 24 h after PDT. As a proof of principle, these maps were compared to actual tumor progression after one week. Complete tumor response was correctly assessed in one animal, while residual viable tumor tissue was detected in the other two at the locations where residual tumor tissue was observed after one week. Conclusion: This study demonstrates that DCE-MRI is an effective tool for early evaluation of PDT tumor treatment. PMID- 29187891 TI - Post-transcriptional Regulation of Genes Related to Biological Behaviors of Gastric Cancer by Long Noncoding RNAs and MicroRNAs. AB - Noncoding RNAs play critical roles in regulating protein-coding genes and comprise two major classes: long noncoding RNAs (lncRNAs) and microRNAs (miRNAs). LncRNAs regulate gene expression at transcriptional, post-transcriptional, and epigenetic levels via multiple action modes. LncRNAs can also function as endogenous competitive RNAs for miRNAs and indirectly regulate gene expression post-transcriptionally. By binding to the 3'-untranslated regions (3'-UTR) of target genes, miRNAs post-transcriptionally regulate gene expression. Herein, we conducted a review of post-transcriptional regulation by lncRNAs and miRNAs of genes associated with biological behaviors of gastric cancer. PMID- 29187894 TI - Material-induced Senescence (MIS): Fluidity Induces Senescent Type Cell Death of Lung Cancer Cells via Insulin-Like Growth Factor Binding Protein 5. AB - Objective: We propose here material-induced senescence (MIS) as a new therapeutic concept that limits cancer progression by stable cell cycle arrest. This study examined for the first time the effect of material fluidity on cellular senescence in lung carcinoma using poly(epsilon-caprolactone-co-D, L-lactide) (P(CL-co-DLLA)) with tunable elasticity and fluidity. Methods: The fluidity was varied by chemically crosslinking the polymer networks: the crosslinked P(CL-co DLLA) shows solid-like properties with a stiffness of 260 kPa, while the non crosslinked polymer exists in a quasi-liquid state with loss and storage moduli of 33 kPa and 11 kPa, respectively. Results: We found that cancer cells growing on the non-crosslinked, fluidic substrate undergo a non-apoptotic form of cell death and the cell cycle was accumulated in a G0/G1 phase. Next, we investigated the expression of biomarkers that are associated with cancer pathways. The cancer cells on the fluidic substrate expressed several biomarkers associated with senescence such as insulin-like growth factor binding protein 5 (IGFBP5). This result indicates that when cancer cells sense fluidity in their surroundings, the cells express IGFBP5, which in turn triggers the expression of tumor suppressor protein 53 and initiates cell cycle arrest at the G1 phase followed by cellular senescence. Furthermore, the cancer cells on the fluidic substrate maintained their epithelial phenotype, suggesting that the cancer cells do not undergo epithelial to mesenchymal transition. Conclusion: By considering these results as the fundamental information for MIS, our system could be applied to induce senescence in treatment-resistant cancers such as metastatic cancer or cancer stem cells. PMID- 29187895 TI - Follicular Stimulating Hormone Accelerates Atherogenesis by Increasing Endothelial VCAM-1 Expression. AB - Rationale: Postmenopausal atherosclerosis (AS) has for decades been attributed to estrogen deficiency. Although the follicular stimulating hormone (FSH) levels rise sharply in parallel, the direct effect of FSH on AS has never been investigated. In this study, we explored the possible role of FSH in the development of AS. Methods: This was a prospective cohort study of 48 healthy premenopausal and 15 postmenopausal women. ApoE knockout mice were used as atherosclerosis model and human umbilical vascular endothelial cells (HUVECs) were cultured as cell model. Serum hormones and vascular cell adhesion molecule-1 (VCAM-1) levels were measured. Real-time PCR, histology for atherosclerotic lesions, immunofluorescence, luciferase assay, transfection experiments, flow chamber adhesion assay and western blot were performed. Results: In ApoE knockout mice, administration of FSH increased the atherosclerotic lesions and serum VCAM 1 concentration. Importantly, in blood samples of postmenopausal women, we detected significantly higher levels of FSH and VCAM-1 compared with those from premenopausal women, and there was a positive correlation between these two molecules. In cultured HUVECs, FSH receptor (FSHR) mRNA and protein expression were detected and FSH enhanced VCAM-1 expression. This effect was mediated by the activation of nuclear factor kappaB (NF-kappaB), which was sequentially enhanced by the activation of PI3K/Akt/mTOR cascade. FSH first enhanced GalphaS activity resulting in elevated cAMP level and PKA activity, which relayed the signals from FSHR to the PI3K/Akt/mTOR cascade. Furthermore, FSHR was detected in endothelial caveolae fraction and interacted with caveolin-1 and GalphaS. The disruption of caveolae or the silencing of caveolin-1 blocked FSH effects on signaling activation and VCAM-1 expression, suggesting the existence of a functional signaling module in membrane caveolae. Finally, FSH increased human monocyte adhesion to HUVECs which was reversed by the VCAM-1 neutralizing antibody. Conclusion: FSHR was located in the membrane caveolae of HUVECs and FSH promoted VCAM-1 expression via FSHR/GalphaS /cAMP/PKA and PI3K/Akt/mTOR/NF-kappaB pathway. This may contribute to the deleterious role of FSH in the development of AS in postmenopausal women.

AB - : Biodegradable polymeric nanomaterials can be directly broken down by intracellular processes, offering a desirable way to solve toxicity issues for cancer diagnosis and treatment. Among them, aliphatic polycarbonates are approved for application in biological fields by the United States Food and Drug Administration (FDA), however, high hydrophobicity, deficient functionality and improper degradation offer significant room for improvement in these materials. METHODS: To achieve progress in this direction, herein, we demonstrate that CO2 based amphiphilic polycarbonates (APC) with improved hydrophilicity and processability can be used as a reliable and efficient platform for tumor imaging. To better investigate their potential, we devised a convenient strategy through conjugation of APC with gadolinium (Gd). RESULTS: The resulting polymeric micelles (APC-DTPA/Gd) exhibit excellent magnetic resonance imaging performance, simultaneously enabling real-time visualization of bioaccumulation and decomposition of polymeric micelles in vivo. Importantly, these micelles can be degraded to renally cleared products within a reasonable timescale without evidence of toxicity. CONCLUSION: Our findings may help the development of CO2 based amphiphilic polycarbonate for cancer diagnosis and treatment, accompanied by their low-toxicity degradation pathway. PMID- 29187897 TI - Glycan and Peptide IgE Epitopes of the TNF-alpha Blockers Infliximab and Adalimumab - Precision Diagnostics by Cross-Reactivity Immune Profiling of Patient Sera. AB - : Biological drugs like therapeutic antibodies are widely used for the treatment of various diseases like inflammatory disorders and cancer. A drawback of these novel treatments is the substantial proportion of patients experiencing adverse reactions such as loss-of-drug effect or hypersensitivity reactions. These reactions are associated with pre-existing and/or developing anti-drug antibodies. Especially IgE development is a risk factor for life-threatening systemic anaphylaxis. METHODS: In order to characterize the individual drug specific serum IgE, an IgE cross-reactivity immune profiling (ICRIP) assay was developed. Individual IgG epitopes of anti-drug antibodies against adalimumab were identified by epitope mapping via peptide microarray. RESULTS: ICRIP analyses of sera from patients treated with the therapeutic antibodies adalimumab (ADL) and infliximab (IFX) reveal individual, distinct IgE binding patterns. IgG epitopes were identified mostly located in the variable region of ADL. CONCLUSIONS: Using ICRIP and peptide microarrays for pharmacovigilance of the TNF alpha blockers IFX and ADL, risk factors and biomarkers before and during therapy shall be identified. These diagnostic systems provide the basis for a safe and efficacious therapy decision for each patient in cases of adverse drug reactions mediated by different types of anti-drug antibodies. PMID- 29187898 TI - Precisely Enumerating Circulating Tumor Cells Utilizing a Multi-Functional Microfluidic Chip and Unique Image Interpretation Algorithm. AB - Enumerating circulating tumor cells (CTCs) has been demonstrably useful in cancer treatment. Although there are several approaches that have proved effective in isolating CTC-like cells, the crucial identification of CTCs continues to rely on the manual interpretation of immunofluorescence images of all cells that have been isolated. This procedure is time consuming and more importantly, CTC identification relies on subjective criteria that may differ between examiners. In this study, we describe the design, testing, and verification of a microfluidic platform that provides accurate and automated CTC enumeration using a common objective criterion. Methods: The platform consists of a multi functional microfluidic chip and a unique image processing algorithm. The microfluidic chip integrates blood filtering, cell isolation, and single cell positioning to ensure minimal cell loss, efficient cell isolation, and fixed arraying of single cells to facilitate downstream image processing. By taking advantage of the microfluidic chip design to reduce calculation loads and eliminate measurement errors, our specially designed algorithm has the capability of rapidly interpreting hundreds of images to provide accurate CTC counts. Results: Following intensive optimization of the microfluidic chip, the image processing algorithm, and their collaboration, we verified the complete platform by enumerating CTCs from six clinical blood samples of patients with breast cancer. Compared to tube-based CTC isolation and manual CTC identification, our platform had better accuracy and reduced the time needed from sample loading to result review by 50%. Conclusion: This automated CTC enumeration platform demonstrates not only a sound strategy in integrating a specially designed multi functional microfluidic chip with a unique image processing algorithm for robust, accurate, and "hands-free" CTC enumeration, but may also lead to its use as a novel in vitro diagnostic device used in clinics and laboratories as readily as a routine blood test. PMID- 29187899 TI - Optimizing fresh specimen staining for rapid identification of tumor biomarkers during surgery. AB - RATIONALE: Positive margin status due to incomplete removal of tumor tissue during breast conserving surgery (BCS) is a prevalent diagnosis usually requiring a second surgical procedure. These follow-up procedures increase the risk of morbidity and delay the use of adjuvant therapy; thus, significant efforts are underway to develop new intraoperative strategies for margin assessment to eliminate re-excision procedures. One strategy under development uses topical application of dual probe staining and a fluorescence imaging strategy termed dual probe difference specimen imaging (DDSI). DDSI uses a receptor-targeted fluorescent probe and an untargeted, spectrally-distinct fluorescent companion imaging agent topically applied to fresh resected specimens, where the fluorescence from each probe is imaged and a normalized difference image is computed to identify tumor-target distribution in the specimen margins. While previous reports suggested this approach is a promising new tool for surgical guidance, advancing the approach into the clinic requires methodical protocol optimization and further validation. METHODS: In the present study, we used breast cancer xenografts and receiver operator characteristic (ROC) curve analysis to evaluate a wide range of staining and imaging parameters, and completed a prospective validation study on multiple tumor phenotypes with different target expression. Imaging fluorophore-probe pair, concentration, and incubation times were systematically optimized using n=6 tissue specimen replicates per staining condition. Resulting tumor vs. normal adipose tissue diagnostic performance were reported and staining patterns were validated via receptor specific immunohistochemistry colocalization. Optimal staining conditions were tested in receptor positive and receptor negative cohorts to confirm specificity. RESULTS: The optimal staining conditions were found to be a one minute stain in a 200 nM probe solution (area under the curve (AUC) = 0.97), where the choice of fluorescent label combination did not significantly affect the diagnostic performance. Using an optimal threshold value determined from ROC curve analysis on a training data set, a prospective study on xenografts resulted in an AUC=0.95 for receptor positive tumors and an AUC = 0.50 for receptor negative (control) tumors, confirming the diagnostic performance of this novel imaging technique. CONCLUSIONS: DDSI provides a robust, molecularly specific imaging methodology for identifying tumor tissue over benign mammary adipose tissue. Using a dual probe imaging strategy, nonspecific accumulation of targeted probe was corrected for and tumor vs. normal tissue diagnostic potential was improved, circumventing difficulties with ex vivo tissue specimen staining and allowing for rapid clinical translation of this promising technology for tumor margin detection during BCS procedures. PMID- 29187900 TI - The cytotoxic effects of dimethyl sulfoxide in mouse preimplantation embryos: a mechanistic study. AB - Rationale: Dimethyl sulfoxide (DMSO) is commonly used as a solvent for water insoluble substances, a vehicle for drug therapy, and a cryoprotectant for cultured cells. DMSO induced embryonic defects and its mechanism of action remains unclear. The rationale is based on the assumption that DMSO supplementation should induce long-term negative effects on both pre- and post implantation embryo development. Methods: DMSO induced oxidative stress, ER stress, autophagy, mitophagy, signaling responsible genes and proteins were determined by RT-qPCR, Western blotting, immunofluorescence, and confocal microscopy. DMSO induced mitochondrial dysfunction was measured by transmission electron microcopy and JC-1 assay. Apoptosis was estimated using TUNEL and comet assay. Post-implantation embryo developmental capability was estimated by implantation site and fetus numbers. Results: Exposure to DMSO induced an early oxidative stress response within 0.5 to 2 h in 1-cell zygotes by disrupting the balance of pro- and anti-oxidants. Notably, DMSO-treated 2-cell embryos showed increased expression of unfolded protein response genes such as Hspa5, Hsp90b1, Ddit3, Atf4, and Xbp1. As a result, the development of many embryos is arrested at the 2-cell, 4-cell, or morula stages in a dose-dependent manner. Further, DMSO induced endoplasmic reticulum stress increased mitochondrial Ca2+ levels, induced mitochondrial depolarization/dysfunction, and induced apoptotic cell death via the JNK/ATF2-dependent pathway. Consequently, treatment with DMSO increased the expression of autophagy initiation-, phagophore elongation-, and autophagosome formation-related genes, as well as localization of PINK1/Parkin, which are the main mediators of mitophagy, in mitochondria. Interestingly, DMSO causes cytotoxic effects in preimplantation embryos by inducing extensive mitophagy and autophagy. Especially, DMSO treatment decreased the inner cell mass and trophectoderm cell numbers as well as mRNA expression of B3gnt5 and Wnt3a in developed blastocysts, which decreased the implantation and developmental rates of full-term offspring after being transferred into pseudopregnant mice. Conclusion: These results provide a significant contribution to finding effective protective agents to combat DMSO mediated reproductive toxicity for application in human embryos in the near future. PMID- 29187902 TI - Copper Manganese Sulfide Nanoplates: A New Two-Dimensional Theranostic Nanoplatform for MRI/MSOT Dual-Modal Imaging-Guided Photothermal Therapy in the Second Near-Infrared Window. AB - Multifunctional nanoplatforms with integrated diagnostic and therapeutic functions have attracted tremendous attention. Especially, the second near infrared (NIR-II) light response-based nanoplatforms hold great potential in cancer theranostic applications, which is because the NIR-II window provides larger tissue penetration depth and higher maximum permissible exposure (MPE) than that of the well-studied first near-infrared (NIR-I) window. Herein, we for the first time present a two-dimensional (2D)-nanoplatform based on Cu2MnS2 nanoplates (NPs) for magnetic resonance imaging (MRI)/multispectral optoacoustic tomography (MSOT) dual-modal imaging-guided photothermal therapy (PTT) of cancer in the NIR-II window. Methods: Cu2MnS2 NPs were synthesized through a facile and environmentally friendly process. A series of experiments, including the characterization of Cu2MnS2 NPs, the long-term toxicity of Cu2MnS2 NPs in BALB/c nude mice, the applications of Cu2MnS2 NPs for in vitro and in vivo MRI/MSOT dual modal imaging and NIR-II PTT of cancer were carried out. Results: The as synthesized Cu2MnS2 NPs exhibit low cytotoxicity, excellent biocompatibility as well as high photothermal conversion efficiency (~49.38%) and outstanding photostability. Together with their good T1-shortening effect and strong absorbance in the NIR-I and NIR-II region, the Cu2MnS2 NPs display high-contrast imaging performance both in MRI and MSOT (900 nm laser source). Moreover, the subsequent in vitro and in vivo results demonstrate that the Cu2MnS2 NPs possess excellent PTT efficacy under 1064 nm laser irradiation with a low power density (0.6 W cm-2). In addition, the detailed long-term toxicity studies further confirming the safety of Cu2MnS2 NPs in vivo. Conclusion: We have developed a new 2D Cu2MnS2 NPs as multifunctional theranostic agents for MRI/MSOT dual-modal imaging-guided PTT of cancer in the NIR-II window. Such biocompatible Cu2MnS2 NPs might provide a new perspective for exploring new 2D-based nanoplatforms with improved properties for clinical applications in the future. PMID- 29187901 TI - Mutational Landscape of cfDNA Identifies Distinct Molecular Features Associated With Therapeutic Response to First-Line Platinum-Based Doublet Chemotherapy in Patients with Advanced NSCLC. AB - Rationale To investigate whether the mutational landscape of circulating cell free DNA (cfDNA) could predict and dynamically monitor the response to first-line platinum-based chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC). Methods Eligible patients were included and blood samples were collected from a phase III trial. Both cfDNA fragments and fragmented genomic DNA were extracted for enrichment in a 1.15M size panel covering exon regions of 1,086 genes. Molecular mutational burden (MMB) was calculated to investigate the relationship between molecular features of cfDNA and response to chemotherapy. Results In total, 52 eligible cases were enrolled and their blood samples were prospectively collected at baseline, every cycle of chemotherapy and time of disease progression. At baseline, alterations of 17 genes were found. Patients with partial response (PR) had significantly lower baseline MMB of these genes than those patients with either stable disease (SD) (P = 0.0006) or progression disease (PD) (P = 0.0074). Further analysis revealed that the mutational landscape of cfDNA from pretreatment blood samples were distinctly different among patients with PR vs. SD/PD. For patients with baseline TP53 mutation, those with PR experienced a significant reduction in MMB whereas patients with SD or PD experienced an increase after two, three or four cycles of chemotherapy. Furthermore, patients with low MMB had superior response rate and significantly longer progression-free survival than those with high MMB. Conclusion This study indicated that the mutational landscape of cfDNA has potential clinical value to predict the therapeutic response to first-line platinum-based doublet chemotherapy in NSCLC patients. At the single gene level, dynamic change of molecular mutational burden of TP53 is valuable to monitor efficacy (and, therefore, might aid in early recognition of resistance and relapse) in patients harboring this mutation at baseline. PMID- 29187903 TI - miR34a/GOLPH3 Axis abrogates Urothelial Bladder Cancer Chemoresistance via Reduced Cancer Stemness. AB - Rationale: Chemoresistance and subsequent recurrence of human urothelial bladder cancer (UBC) is partially driven by a subpopulation of tumor initiating cells, namely cancer stem cells (CSCs). However, the underlying molecular mechanism in chemotherapy-induced CSCs enrichment and following chemoresistance and recurrence remains largely unclear. Methods: Gemcitabine and cisplatin (GC) chemoresistant cell lines (T24 GC 3rd and 5637 GC 3rd cells) and the chemo-sensitive UBC cell lines T24 and 5637 were established in vivo for the investigation of acquired resistance mechanisms. The role of miR34a/GOLPH3 axis in regulating UBC chemoresistance and recurrence was evaluated in cell and animal models. The expression levels of miR34a/GOLPH3 axis and CSCs markers were assayed in specimens of UBC. The association of GOLPH3 with clinicopathologic features and prognosis was analysed. Results: RT-PCR and western blotting confirmed that the expression levels of miR34a were decreased and GOLPH3 were increased in GC chemoresistant UBC cell lines. Downregulation of miR34a resulted in the overexpression of GOLPH3, which is a target gene of miR34a confirmed by luciferase experiment. The ectopic expression of miR34a decreased the stem cell properties of chemoresistant UBC cells and re-sensitized these cells to GC treatment in vitro and in vivo. Moreover, miR34a/GOLPH3 axis has obvious clinical relevance with prognosis and recurrence in human UBC patients with standard GC chemotherapy. Conclusion: Our results suggest that miR34a/GOLPH3 axis exert key role in CSCs involved UBC drug resistance and recurrence and warrant further development as a promising therapeutic approach in treating drug-resistant UBC. PMID- 29187904 TI - Multimodality Imaging of Angiogenesis in a Rabbit Atherosclerotic Model by GEBP11 Peptide Targeted Nanoparticles. AB - Background and Aims: Angiogenesis is an important pathological process during progression of plaque formation, which can result in plaque hemorrhage and vulnerability. This study aims to explore non-invasive imaging of angiogenesis in atherosclerotic plaque through magnetic resonance imaging (MRI) and positron emission tomography (PET) by using GEBP11 peptide targeted magnetic iron oxide nanoparticles in a rabbit model of atherosclerosis. Methods: The dual-modality imaging probe was constructed by coupling 2, 3-dimercaptosuccinnic acid-coated paramagnetic nanoparticles (DMSA-MNPs) and the PET 68Ga chelator 1,4,7 triazacyclononane-N, N', N''-triacetic acid (NOTA) to GEBP11 peptide. The atherosclerosis model was induced in New Zealand white rabbits by abdominal aorta balloon de-endothelialization and atherogenic diet for 12 weeks. The plaque areas in abdominal artery were detected by ultrasound imaging and Oil Red O staining. Immunofluorescence staining and Prussian blue staining were applied respectively to investigate the affinity of GEBP11 peptide. MTT and flow cytometric analysis were performed to detect the effects of NGD-MNPs on cell proliferation, cell cycle and apoptosis in Human umbilical vein endothelial cells (HUVECs). In vivo MRI and PET imaging of atherosclerotic plaque were carried out at different time points after intravenous injection of nanoparticles. Results: The NGD-MNPs with hydrodynamic diameter of 130.8 nm +/- 7.1 nm exhibited good imaging properties, high stability, low immunogenicity and little cytotoxicity. In vivo PET/MR imaging revealed that 68Ga-NGD-MNPs were successfully applied to visualize atherosclerotic plaque angiogenesis in the rabbit abdominal aorta. Prussian blue and CD31 immunohistochemical staining confirmed that NGD-MNPs were well co localized within the blood vessels' plaques. Conclusion:68Ga-NGD-MNPs might be a promising MR and PET dual imaging probe for visualizing the vulnerable plaques. PMID- 29187905 TI - Nanoparticle Delivery of miR-34a Eradicates Long-term-cultured Breast Cancer Stem Cells via Targeting C22ORF28 Directly. AB - Rationale: Cancer stem cells (CSCs) have been implicated as the seeds of therapeutic resistance and metastasis, due to their unique abilities of self renew, wide differentiation potentials and resistance to most conventional therapies. It is a proactive strategy for cancer therapy to eradicate CSCs. Methods: Tumor tissue-derived breast CSCs (BCSC), including XM322 and XM607, were isolated by fluorescence-activated cell sorting (FACS); while cell line-derived BCSC, including MDA-MB-231.SC and MCF-7.SC, were purified by magnetic-activated cell sorting (MACS). Analyses of microRNA and mRNA expression array profiles were performed in multiple breast cell lines. The mentioned nanoparticles were constructed following the standard molecular cloning protocol. Tissue microarray analysis has been used to study 217 cases of clinical breast cancer specimens. Results: Here, we have successfully established four long-term maintenance BCSC that retain their tumor-initiating biological properties. Our analyses of microarray and qRT-PCR explored that miR-34a is the most pronounced microRNA for investigation of BCSC. We establish hTERT promoter-driven VISA delivery of miR 34a (TV-miR-34a) plasmid that can induce high throughput of miR-34a expression in BCSC. TV-miR-34a significantly inhibited the tumor-initiating properties of long term-cultured BCSC in vitro and reduced the proliferation of BCSC in vivo by an efficient and safe way. TV-miR-34a synergizes with docetaxel, a standard therapy for invasive breast cancer, to act as a BCSC inhibitor. Further mechanistic investigation indicates that TV-miR-34a directly prevents C22ORF28 accumulation, which abrogates clonogenicity and tumor growth and correlates with low miR-34 and high C22ORF28 levels in breast cancer patients. Conclusion: Taken together, we generated four long-term maintenance BCSC derived from either clinical specimens or cell lines, which would be greatly beneficial to the research progress in breast cancer patients. We further developed the non-viral TV-miR-34a plasmid, which has a great potential to be applied as a clinical application for breast cancer therapy. PMID- 29187906 TI - The Changing Therapeutic Role of Chemo-radiotherapy for Loco-regionally Advanced Nasopharyngeal Carcinoma from Two/Three-Dimensional Radiotherapy to Intensity Modulated Radiotherapy: A Network Meta-Analysis. AB - Purpose: We used randomized trials of radiotherapy (RT) with or without chemotherapy in non-metastatic nasopharyngeal carcinoma to investigate the survival benefit of chemoradiotherapy regimens between two/three-dimensional radiotherapy (2D/3D RT) and intensity-modulated radiotherapy (IMRT). Methods: Overall, 27 trials and 7,940 patients were included. Treatments were grouped into seven categories including RT alone, induction chemotherapy (IC) followed by RT (IC-RT), RT followed by adjuvant chemotherapy (RT-AC), IC followed by RT followed by AC (IC-RT-AC), concurrent chemo-radiotherapy (CRT), IC followed by CRT (IC CRT), and CRT followed by AC (CRT-AC). To distinguish between 2D/3D RT and IMRT, three categories in IMRT were newly added, including CRT in IMRT, IC-CRT in IMRT, and CRT-AC in IMRT. The P score was used to rank the treatments. Results: Both fixed- and random-effects frequentist and Bayesian network meta-analysis models were applied, which provided similar results and the same ranking. IC-CRT was the most effective regimen compared with CRT-AC and CRT in the IMRT era for overall survival (OS) (HR, 95% CI, IC-CRT vs. CRT-AC, 0.61 (0.45, 0.82); IC-CRT vs. CRT 0.65 (0.47, 0.91)), progression-free survival (PFS) (0.69 (0.54, 0.88); 0.63 (0.49, 0.80)), and distant metastasis-free survival (DMFS) (0.58 (0.28, 1.21); 0.60 (0.42, 0.85)). CRT-AC achieved the highest survival benefit compared with CRT, and IC-CRT for loco-regional relapse-free survival (LRRFS) (0.44 (0.15, 1.28); 0.72 (0.22, 2.33)). Among these 10 categories, after distinguishing between 2D/3D RT and IMRT, IC-CRT in IMRT ranked first for OS, PFS, and DMFS, and CRT-AC in IMRT ranked first for LRRFS. Conclusion: IC-CRT should be the most suitable regimen for loco-regionally advanced NPC in the IMRT era. PMID- 29187907 TI - Long non-coding RNA UICLM promotes colorectal cancer liver metastasis by acting as a ceRNA for microRNA-215 to regulate ZEB2 expression. AB - Long non-coding RNAs (lncRNAs) are involved in the pathology of various tumors, including colorectal cancer (CRC). However, the role of lncRNA in CRC liver metastasis remains unclear. Methods: a microarray was performed to identify the differentially expressed lncRNAs between CRC tissues with and without liver metastasis. Survival analysis was evaluated using the Kaplan-Meier method and assessed using the log-rank test. In vitro and in vivo assays were preformed to explore the biological effects of the differentially expressed lncRNA in CRC cells. Results: the lncRNA UICLM (up-regulated in colorectal cancer liver metastasis) was significantly up-regulated in cases of CRC with liver metastasis. Moreover, UICLM expression was higher in CRC tissues than in normal tissues, and UICLM expression was associated with poor patient survival. Knockdown of UICLM inhibited CRC cell proliferation, invasion, epithelial-mesenchymal transition (EMT) and CRC stem cell formation in vitro as well as tumor growth and liver metastasis in vivo. Ectopic expression of UICLM promoted CRC cell proliferation and invasion. Mechanistic investigations revealed that UICLM induced its biological effects by regulating ZEB2, as the oncogenesis facilitated by UICLM was inhibited by ZEB2 depletion. Further study indicated that UICLM acted as a competing endogenous RNA (ceRNA) for miR-215 to regulate ZEB2 expression. Conclusions: taken together, our findings demonstrate how UICLM induces CRC liver metastasis and may offer a novel prognostic marker and therapeutic target for this disease. PMID- 29187910 TI - Injection of nanoparticles into cloven-hoof animals: Asking for trouble. AB - This article aims at alerting scientists working with nanoparticles or microparticles about the specific adverse reactions due to the intravascular pulmonary macrophages present in pigs and other cloven-hoof animals, but not in humans. The history of a 25-year old study of an ultrasound contrast agent is used to illustrate these differences. PMID- 29187908 TI - Interleukin-6 Mediates Post-Infarct Repair by Cardiac Explant-Derived Stem Cells. AB - : Although patient-sourced cardiac explant-derived stem cells (EDCs) provide an exogenous source of new cardiomyocytes post-myocardial infarction, poor long-term engraftment indicates that the benefits seen in clinical trials are likely paracrine-mediated. Of the numerous cytokines produced by EDCs, interleukin-6 (IL 6) is the most abundant; however, its role in cardiac repair is uncertain. In this study, a custom short-hairpin oligonucleotide lentivirus was used to knockdown IL-6 in human EDCs, revealing an unexpected pro-healing role for the cytokine. METHODS: EDCs were cultured from atrial appendages donated by patients undergoing clinically indicated cardiac surgery. The effects of lentiviral mediated knockdown of IL-6 was evaluated using in vitro and in vivo models of myocardial ischemia. RESULTS: Silencing IL-6 in EDCs abrogated much of the benefits conferred by cell transplantation and revealed that IL-6 prompts cardiac fibroblasts and macrophages to reduce myocardial scarring while increasing the generation of new cardiomyocytes and recruitment of blood stem cells. CONCLUSIONS: This study suggests that IL-6 plays a pivotal role in EDC-mediated cardiac repair and may provide a means of increasing cell-mediated repair of ischemic myocardium. PMID- 29187909 TI - A New Theranostic System Based on Endoglin Aptamer Conjugated Fluorescent Silica Nanoparticles. AB - Background: Tumor vessels can potentially serve as diagnostic, prognostic and therapeutic targets for solid tumors. Fluorescent dyes are commonly used as biological indicators, while photobleaching seriously hinders their application. In this study, we aim to generate a fluorescent silica nanoparticles (FSiNPs) theranostic system marked by the mouse endgolin (mEND) aptamer, YQ26. Methods: A highly specific YQ26 was selected by using gene-modified cell line-based SELEX technique. FSiNPs were prepared via the reverse microemulsion method. The YQ26 FSiNPs theranostic system was developed by combining YQ26 with the FSiNPs for in vivo tumor imaging, treatment and monitoring. Results: Both in vitro experiments (i.e. cellular and tumor tissue targeting assays) and in vivo animal studies (i.e. in vivo imaging and antitumor efficacy of YQ26-FSiNPs) clearly demonstrated that YQ26-FSiNPs could achieve prominently high targeting efficiency and therapeutic effects via aptamer YQ26-mediated binding to endoglin (END) molecule. Conclusion: This simple, sensitive, and specific YQ26-FSiNPs theranostic system has a great potential for clinical tumor targeting imaging and treatment. PMID- 29187911 TI - Oval Cells Contribute to Fibrogenesis of Marginal Liver Grafts under Stepwise Regulation of Aldose Reductase and Notch Signaling. AB - Background and Aims: Expanded donor criteria poses increased risk for late phase complications such as fibrosis that lead to graft dysfunction in liver transplantation. There remains a need to elucidate the precise mechanisms of post transplant liver damage in order to improve the long-term outcomes of marginal liver grafts. In this study, we aimed to examine the role of oval cells in fibrogenic development of marginal liver grafts and explore the underlying mechanisms. Methods: Using an orthotopic rat liver transplantation model and human post-transplant liver biopsy tissues, the dynamics of oval cells in marginal liver grafts was evaluated by the platform integrating immuno-labeling techniques and ultrastructure examination. Underlying mechanisms were further explored in oval cells and an Aldose reductase (AR) knockout mouse model simulating marginal graft injury. Results: We demonstrated that activation of aldose reductase initiated oval cell proliferation in small-for-size fatty grafts during ductular reaction at the early phase after transplantation. These proliferative oval cells subsequently showed prevailing biliary differentiation and exhibited features of mesenchymal transition including dynamically co expressing epithelial and mesenchymal markers, developing microstructures for extra-cellular matrix degradation (podosomes) or cell migration (filopodia and blebs), and acquiring the capacity in collagen production. Mechanistic studies further indicated that transition of oval cell-derived biliary cells toward mesenchymal phenotype ensued fibrogenesis in marginal grafts under the regulation of notch signaling pathway. Conclusions: Oval cell activation and their subsequent lineage commitment contribute to post-transplant fibrogenesis of small for-size fatty liver grafts. Interventions targeting oval cell dynamics may serve as potential strategies to refine current clinical management. PMID- 29187913 TI - An online monitor of the oxidative capacity of aerosols (o-MOCA). AB - The capacity of airborne particulate matter to generate reactive oxygen species (ROS) has been correlated with the generation of oxidative stress both in vitro and in vivo. The cellular damage from oxidative stress, and by implication with ROS, is associated with several common diseases, such as asthma and chronic obstructive pulmonary disease (COPD), and some neurological diseases. Yet currently available chemical and in vitro assays to determine the oxidative capacity of ambient particles require large samples, analyses are typically done offline, and the results are not immediate. Here we report the development of an online monitor of the oxidative capacity of aerosols (o-MOCA) to provide online, time-resolved assessment of the capacity of airborne particles to generate ROS. Our approach combines the Liquid Spot Sampler (LSS), which collects particles directly into small volumes of liquid, and a chemical module optimized for online measurement of the oxidative capacity of aerosol using the dithiothreitol (DTT) assay. The LSS uses a three-stage, laminar-flow water condensation approach to enable the collection of particles as small as 5 nm into liquid. The DTT assay has been improved to allow the online, time-resolved analysis of samples collected with the LSS but could be adapted to other collection methods or offline analysis of liquid extracts. The o-MOCA was optimized and its performance evaluated using the 9,10-phenanthraquinone (PQ) as a standard redox-active compound. Laboratory testing shows minimum interferences or carryover between consecutive samples, low blanks, and a reproducible, linear response between the DTT consumption rate (nmol min-1) and PQ concentration (MUM). The calculated limit of detection for o-MOCA was 0.15 nmol min-1. The system was validated with a diesel exhaust particle (DEP) extract, previously characterized and used for the development, improvement, and validation of the standard DTT analysis. The DTT consumption rates (nmol min-1) obtained with the o-MOCA were within experimental uncertainties of those previously reported for these DEP samples. In ambient air testing, the fully automated o-MOCA was run unattended for 3 days with 3 h time resolution and showed a diurnal and daily variability in the measured consumption rates (nmol min-1 m-3). PMID- 29187914 TI - Phonological and Semantic Cues to Learning from Word-Types. AB - Word-types represent the primary form of data for many models of phonological learning, and they often predict performance in psycholinguistic tasks. Word types are often tacitly defined as phonologically unique words. Yet, an explicit test of this definition is lacking, and natural language patterning suggests that word meaning could also act as a cue to word-type status. This possibility was tested in a statistical phonotactic learning experiment in which phonological and semantic properties of word-types varied. During familiarization, the learning targets-word-medial consonant sequences-were instantiated either by four related word-types or by just one word-type (the experimental frequency factor). The expectation was that more word-types would lead participants to generalize the target sequences. Regarding semantic cues, related word-types were either associated with different referents or all with a single referent. Regarding phonological cues, related word-types differed from each other by one, two, or more phonemes. At test, participants rated novel wordforms for their similarity to the familiarization words. When participants heard four related word-types, they gave higher ratings to test words with the same consonant sequences, irrespective of the phonological and semantic manipulations. The results support the existing phonological definition of word-types. PMID- 29187915 TI - Does Love Influence Athletic Performance? The Perspectives of Olympic Athletes. AB - In this brief report, we provide an initial account of the association between love and athletic performance from the perspective of Olympic athletes. We posit that Romantic Passionate Love (RPL) and athletic performance may both involve the reward-motivation system of the brain. Based on this premise, we explored whether activation in one domain (love) might influence the other (sport). Our investigation was framed using Sternberg's triangular theory of love. Twenty Olympic athletes representing different sports were interviewed at the Games. Most athletes (n = 15) reported that their performance was better while in love; however, qualitative responses suggested that the benefits were correlated with rather than resulting from RPL. Although the athletes were provided with a definition of RPL and affirmed that their relationship met the criteria, interview responses reflected companionate rather than passionate love, suggesting that RPL may be differentially conceptualized across cultures. The study provides preliminary data that may be used to inform and refine future work on this topic. PMID- 29187912 TI - Cell-cycle-specific Cellular Responses to Sonoporation. AB - Microbubble-mediated sonoporation has shown its great potential in facilitating intracellular uptake of gene/drugs and other therapeutic agents that are otherwise difficult to enter cells. However, the biophysical mechanisms underlying microbubble-cell interactions remain unclear. Particularly, it is still a major challenge to get a comprehensive understanding of the impact of cell cycle phase on the cellular responses simultaneously occurring in cell membrane and cytoskeleton induced by microbubble sonoporation. Methods: Here, efficient synchronizations were performed to arrest human cervical epithelial carcinoma (HeLa) cells in individual cycle phases. The, topography and stiffness of synchronized cells were examined using atomic force microscopy. The variations in cell membrane permeabilization and cytoskeleton arrangement induced by sonoporation were analyzed simultaneously by a real-time fluorescence imaging system. Results: The results showed that G1-phase cells typically had the largest height and elastic modulus, while S-phase cells were generally the flattest and softest ones. Consequently, the S-Phase was found to be the preferred cycle for instantaneous sonoporation treatment, due to the greatest enhancement of membrane permeability and the fastest cytoskeleton disassembly at the early stage after sonoporation. Conclusion: The current findings may benefit ongoing efforts aiming to pursue rational utilization of microbubble-mediated sonoporation in cell cycle targeted gene/drug delivery for cancer therapy. PMID- 29187916 TI - [Epidemiological, clinical and therapeutic aspects of blunt abdominal trauma in patients undergoing surgery at the General Hospital of National Reference of N'Djamena, Chad: about 49 cases]. AB - Introduction: Blunt abdominal traumas are common. Methods: We retrospectively reviewed the medical records of 49 patients with blunt abdominal trauma who underwent surgery at the General Hospital of National Reference of N'Djamena, Chad over a period of 5 years. Epidemiological, clinical and therapeutic parameters of patients were studied. Results: The study included 42 men and 7 women, mean age 21.3 years. The causes of blunt abdominal traumas were: road traffic accidents in 61.2% of cases; wall collapses (14.3%); assaults (8.2%). Blunt abdominal traumas were more frequent in August (14.28%) and October (16.32%). The waiting time for admission in hospital was 6-12h in 43% of cases. At discharge, wounded patients used private car in 85.7% of cases. Clinically, patients were often hemodynamically stable (55.1%). Medical imaging was dominated by direct radiography of the abdomen (57.1%). The most observed lesions were those located only in the small intestine (16.32%) or related to that of the bladder (8.16%) and spleen (2.04%). Laparotomy was negative in 6.12% of cases. Morbidity (12.2%) was dominated by abdominal wall abscess. Mortality rate was 6.1%. Conclusion: Road traffic accidents are the leading cause of blunt abdominal traumas. It is important to minimize delays in diagnosis, and treatment. Road safety measures should be implemented to prevent accidents. PMID- 29187917 TI - Multi-antibiotic resistant extended-spectrum beta-lactamase producing bacteria pose a challenge to the effective treatment of wound and skin infections. AB - Introduction: The increasing incidence of antibiotic resistant bacteria is a concern both to the clinicians and the patients due to obvious consequences such as treatment failures, prolonged patients' stay in hospital and nosocomial infections. The choice of the first antibiotic therapy in emergency wards in hospitals is usually not based on patient-specific microbial culture and susceptibility test result.This study is aimed at profiling extended-spectrum beta-lactamase (ESBL) producing bacteria associated with wound injuries and highlighting their multi-antibiotic resistance character. Methods: Sixty-three wound swab samples were collected and cultured on nutrient agar and on selective media. Evaluation for ESBL production was by phenotypic method while the antibiogram screening was by disc-diffusion. Results: The wounds evaluated were diabetic sore (14), cancer wounds (12), surgical wounds (17), wounds due to road traffic accidents (10) and wounds from fire burn (10). The result showed that 61 wounds were infected and the prevalence of the infecting pathogens was Escherichia coli 17.46%, Klebsiella Pneumonia 14.28%, Salmonella typhi 12.79%, Pseudomonas Aeruginosa 34.92% and Staphylococcus aureus 17.46%. Thirty four (55.74 %) isolates were ESBL producers, greater than 50% of which being Pseudomonas Aeruginosa. The antibiogram study of the ESBL producers showed multi drug resistance with resistance highest against ampicillin (100%), followed by cephalosporins: cefuroxime (94.12%) and ceftriaxone (61.76%). No resistance was recorded against the beta-lactamase inhibitors: amoxicillin/clavulanate and ceftriaxone/sulbactam. There was a high incidence (55.74 %) of ESBL-producing microbes in the wounds. The isolates were mostly multi-antibiotic resistant. Conclusion: Multi-drug resistant ESBL-producing bacteria are common in wound infections in the community. However, amoxicillin/clavulanate or ceftriaxone/sulbactam may be used to treat most patients with such infections in the hospital. This may guide antibiotic selection and use in trauma, most especially in resource limited countries where laboratory test is unaffordable for a majority of patients. PMID- 29187918 TI - Evaluation of wetting ability of five new saliva substitutes on heat-polymerized acrylic resin for retention of complete dentures in dry mouth patients: a comparative study. AB - Introduction: The aim of this study was to evaluate & compare the wetting ability of five saliva substitutes & distilled water on heat-polymerized acrylic resin. Contact angle of the saliva substitute on denture base can be taken as an indicator of wettability. Good wetting of heat-polymerized acrylic resin is critical for optimum retention of complete dentures. Methods: Two hundred & forty samples of heat-polymerized acrylic resin were fabricated using conventional method. 240 samples divided into 6 groups with 40 samples in each group. Advancing & Receding contact angles were measured using Contact Angle Goniometer & DSA4 software analysis. Results: Anova test was carried out to test the significance in difference of contact angle values in the six groups. The mean of advancing angle values & mean of receding angle values of all the six groups has shown statistically significant difference between the groups. The mean of angle of hysteresis values of all the six groups are statistically not significant between the groups. A multiple comparison using Bonferroni's test was carried out to verify the significance of difference between the contact angles in a pair of groups. Statistically significant difference was seen when Aqwet (Group II) was compared to Distilled water (Group I), Wet Mouth (Group III), E-Saliva (Group IV), Biotene (Group V), and Moi-Stir (Group VI). Conclusion: The contact angles of five saliva substitutes and distilled water were measured and compared. Group II (AQWET) has the lowest advancing and receding contact angle values and the highest angle of hysteresis on heat-polymerized acrylic resin. Based on contact angle values, Group II (AQWET) has the best wetting ability on heat-cured acrylic resins. The ability of saliva to wet the denture surface is one of the most important properties for complete denture retention in dry mouth cases. PMID- 29187919 TI - Factors affecting access to information on routine immunization among mothers of under 5 children in Kaduna State Nigeria, 2015. AB - Introduction: Immunization is one of the most effective interventions to prevent disease and early child death. A substantial number of children worldwide do not complete immunization schedules because neither health services nor conventional communication mechanisms regularly reach their communities. Knowledge and perception of mothers/caregivers regarding VPDs influence demand and utilization of immunization services. We examined the associations between knowledge, perception and information on routine immunization received by mothers/caregivers in Kaduna State. Methods: We enrolled 379 eligible caregivers in a community based cross-sectional study. We sampled respondents using multistage sampling technique. We collected data on socio-demographic characteristics; knowledge and perception on routine immunization using semi-structured interviewer-administered questionnaire. We conducted bivariate analysis and logistic regression using Epi InfoTM version 7 at 5% level of significance. Results: Mean age of respondents was 28.6 years (standard deviation=+/-6.6 years), 34% completed secondary school, 65% were unemployed, 49% lived in rural settlements. Among respondents' children 53.3% were females and 62.8% fell within 2nd-5th birth order. Only 15.6% of these children were fully immunized. Seventy-five percent of respondent did not obtain information on routine immunization within 12 months prior to the study. About 64% had unsatisfactory knowledge while 55.4% exhibited poor perceptions regarding routine immunization. Commonest source of information was radio (61.61%). On logistic regression educated participants (Adjusted odds ratio (AOR)=1.9, 95% CI: 1.1-3.3), mothers' perception (AOR=2.6, 95% CI: 1.5-4.5) and monogamous family setting (AOR=2.4, 95% CI: 0.2-0.6) were likely to have obtained information on routine immunization. Conclusion: There is low access to information, poor maternal knowledge on routine immunization with low vaccination coverage in this community. Efforts should be made by the Governments to scale up sensitization of mothers/caregivers to improve their knowledge on routine immunization through radio jingles. PMID- 29187920 TI - [Benign tumors of the breast in the department of senology at the University Hospital Aristide Le Dantec, Dakar (Senegal)]. AB - Introduction: This study aimed to identify the epidemiological, clinical and therapeutic features of benign tumors of the breast treated in the department of senology at the university hospital Aristide Le Dantec, Dakar. Methods: We conducted a cross-sectional, descriptive and analytical study of 220 patients treated in the Department of Senology at the University Hospital Aristide Le Dantec, Dakar over the period from 1 January 2008 to 31 December 2013. Results: 220 patients out of 984 consultants had benign tumor of the breast (22.5%). Benign tumors of the breast accounted for 58.2% of tumor pathologies. The average age was 24 years. The age group 11-30 years was the most represented (70%). The quasi-totality of patients were women of childbearing age (95%), 58.6% were nulliparous women. The main reason for consultation was a breast mass in 94.5% of cases. The left side was most often affected (49.5%), especially the upper outer quadrant (41.6%). 145 patients (65.9% of cases) underwent ultrasound. Cytologic examination showed conjunctival epithelial hyperplasia in almost all cases (96.1%). 44 women underwent histologic examination, which confirmed the histologic nature of the lesions. Fibroadenoma and fibrocystic changes were the most retained diagnoses, accounting for 86.3% and 5.9% respectively. 28 patients (12.7%) underwent lumpectomy, all tumor types were taken together. The majority of patients had follow-up appointments within 3 months, with favorable outcome. Conclusion: Benign tumors are very frequent in senology consultations. The recommended diagnostic approach combines the clinico-radio-cytological triad and, in case of doubt or discrepancy, biopsy or surgical resection are essential. Surgery is not always the treatment of choice. This is based on the nature of the tumor. PMID- 29187921 TI - Giant gastric trichobezoar in a young female with Rapunzel syndrome: case report. AB - Rapunzel syndrome is an extremely rare complication of a gastric trichobezoar in. We report here the unusual case of a case of a 16 years old girl presented with severe abdominal pain and vomiting. Clinical examination revealed a malnourished girl, with presence of a mobile and sensitive abdominal mass of 20x15 cm witch filled the upper quadrant. An abdominal computed tomography scan showed a heterogeneous mass occupying the whole stomach cavity with extension into the third portion of the duodenum. A diagnostic of giant trichobezoar is suspected after further questioning reveling a trichotillomania, trichophagia and onychophagia. The removal of the trichobezoar endoscopically failed and it was possible to pull only few fibers of hair to comfort the diagnostic. She was subjected to an exploratory laparotomy. An antral gastrostomy were performed and a 25x10x7 cm trichobezoar was extracted. The patient had an uneventful postoperative outcome and was derived to psychiatry. Rapunzel syndrome is an uncommon trichobezoar, it's commonly found in young females usually with an underlying psychiatric disorder. Management requires gastrotomy. A psychiatric assessment and a long-term follow-up are advocated as a regular part of treatment to prevent recurrence.

AB - Introduction: The aim of our study was to assess a standardized supervisory grid as a new supervision tool being used in the laboratories of leishmaniasis. Methods: We conducted a pilot trial to evaluate the ongoing performances of seven provincial laboratories, in four provinces in Morocco, over a period of two years, between 2006 and 2014. This study detailed the situation in provincial laboratories before and after the implementation of the supervisory grid. A total of twenty-one grids were analyzed. Results: In 2006, the results clearly showed a poor performance of laboratories: need for training (41.6%), staff performing skin biopsy (25%), shortage of materials and reagents (65%), non-compliant document and local management (85%). Several corrective actions were conducted by the National Reference Laboratory (LNRL) of Leishmaniasis during the study period. In 2014, the LNRL recorded a net improvement of the performances of the laboratories. The need for training, the quality of the biopsy, the supply of tools and reagents were met and an effective coordination activity was established between the LNRL and the provincial laboratories. Conclusion: This trial shows the effectiveness of the grid as a high quality supervisory tool and as a cornerstone of making progress on fight programs against leishmaniases. PMID- 29187923 TI - [IIA2-Y-type urethral duplication]. AB - Urethral duplications are extremely rare congenital malformations. The most used classification is that of Effmann and Lebowitz, describing 6 types of urethral duplications. The under type IIA2-Y is one of the most rare duplications corresponding to duplicated urethra originating from the bladder neck and extending toward the ectopic perineal or anal insertion. We here report the case of a 32 year patient, with no previous personal history, suffering from urinary leakage during and after urination since childhood. Clinical examination showed a bottleneck at the level to the perineum initially suggesting urethral fistula. However, the absence of fistula-associated urinary disorders as well as urinary leakage since childhood refuted this assumption. The patient underwent Micturating Retrograde Urethrocistography after perineal orifice catheterization confirming well systematized tract. Surgical exploration was based on excision of the duplicate urethra after hydrophilic catheterization by inserting hydrophilic guidewire up to its anastomosis at the level of the prostate. The examination of the surgical specimen confirmed the diagnosis of supernumerary urethra. PMID- 29187924 TI - Social and cultural barriers to husbands' involvement in maternal health in rural Gambia. AB - Introduction: While many studies have documented a number of socio-cultural barriers to male involvement in maternal health, in The Gambia very little information is known about the social and cultural practices that characterized male involvement in maternal health. This study aims to explore some of the underlying social and cultural factors affecting husbands' involvement in maternal health issues pertaining to pregnancy and delivery in rural Gambia. Methods: Five focus group discussions and six in-depth interviews were conducted among rural men and traditional birth attendants in five areas of rural Gambia. The discussion was directed to the roles of male partners in pregnancy and delivery and the difficulties they face regarding taking care of their wives. The data resulting from the discussion was audio-recorded, transcribed verbatim, and analyzed thematically. Results: In general, rural Gambian men and traditional birth attendants (TBAs) reported that husbands' involvement in maternal health is highly desirable, but is influenced by many factors, such as the traditional conceptualization associated with pregnancy and delivery as women's domain. In addition, many men do not believe that pregnancy chores warrant their efforts compared to other competing social responsibilities. This issue may be more complicated in polygamous marriages where there is rivalry among co-wives and in neighborhoods where men who help with house chores may be subjected to mockery. Conclusion: These findings suggest that husbands' involvement in maternal health in The Gambia is influenced by the prevailing social and cultural practices of gender role and norms, which are also at the root of maternal health problems.

PMID- 29187926 TI - [Management of moderate and severe dysthyroid orbitopathy: about 22 cases]. AB - Our study aimed to describe the therapeutic management of moderate and severe dysthyroid orbitopathies and to evaluate the factors associated with optic neuropathy as well as the prognostic factors of poor visual outcome using a statistical analysis. We conducted a retrospective study of 22 patients presenting with moderate to severe dysthyroid orbitopathy in at least one eye and hospitalized in the Department of Ophthalmology at the University Hospital Farhat Hached, Sousse over the period from 1998 to 2015. Therapeutic indications were based on activity and severity criteria of the Eugogo (European Group On Graves' Orbitopathy) as well as on the assessment of prognostic factors of poor visual outcome. The average age of our patients was 40 years, with a slight male predominance (54.5%). 68.2% of patients were euthyroid, 18.2% had a history of smoking. The most significantly associated factor with neuropathy was a compression in the orbital apex (p = 0.03). Treatment was based on intravenous corticosteroid therapy and/or orbital decompression based on disease activity and severity. Overall evolution after treatment was marked by an improvement in inflammatory signs and by the reduction of exophthalmia. Visual prognosis was worse in elderly patients (p = 0.0001), male sex (p = 0.03) and treated by iratherapy (p = 0.04). Given the limits of a retrospective study, our results were generally consistent with the literature. The assessment and the management of dysthyroid orbitopathy are not well understood. Cohort, probably multicenter studies should be conducted to improve its management. PMID- 29187927 TI - Our chairman is very efficient: community participation in the delivery of primary health care in Ibadan, Southwest Nigeria. AB - Introduction: Community participation is rapidly being viewed as a requirement for the successful acceptance of health services; it integrates a complicated process which involves customs, beliefs, culture and power relations, not only structures and policies. Yet, there is a wide knowledge gap and changes favouring community participation in primary health care is still minimal. This study aims to assess the process indicators and other factors influencing community participation in the delivery of primary health care. Methods: This descriptive cross-sectional study using qualitative methods was conducted in Ibadan South East Local Government Area of Oyo State, Nigeria between July and September, 2015. The interview and Focus Group Discussion guides centred around five participation indicators of needs assessment, leadership, resource mobilization, organization and management was used to collect data. A total of 12 in-depth interviews and four FGDs were conducted among male and female respondents consisting PHC service providers and community members purposively selected from four wards of the LGA. Spidergrams were constructed to visualize the levels of community participation from respondents' opinions. Results: About 51.1% of the 45 respondents (with mean age 45.5 +/- 8.09 years) were males. The respondents view community participation in the delivery of PHC in the LGA as being wide (open). Majority of the service users believe and agree that the level of community participation in their wards is about average while the service providers believed that participation was very high. However, respondents identified female representation, collaboration with pre-existing community structures, top-down and bottom-up approach to service delivery as factors affecting community participation in PHC delivery. Conclusion: This study provides a baseline data on community participation in the delivery of primary health care. Community participation is still an important principle in the delivery of primary health care and it guarantees the positive changes desired in the uptake and sustainability of primary health care programmes. PMID- 29187928 TI - Hormone-receptor expression status of epithelial ovarian cancer in Ibadan, South western Nigeria. AB - Introduction: Epidemiological evidence strongly suggests that steroid hormones are implicated in the pathogenesis of ovarian cancer. Estrogen receptor (ER) and Progesterone receptor (PR) are prognostic indicators for a number of epithelial tumors and may play the same role in ovarian cancers. This study aims to evaluate the expression of ER and PR in epithelial ovarian cancer (EOC) in an African population and compare it with other prognostic factors such as age, International Federation of Gynaecology and Obstetrics (FIGO) stage, grade and histological subtype. Methods: Ninety cases of histologically confirmed EOC were reviewed. Immunohistochemistry was used to assess their ER and PR expression status and was then compared with other demographic variables using statistical methods, with level of significance set at p < 0.05. Results: 30.2% and 8.3% of serous and mucinous carcinomas respectively were ER positive while 41.2% and 22.5% of both tumour types were PR positive. One of the two endometrioid carcinomas showed PR expression but neither were positive for ER. The only case of Brenner tumour in the series was ER positive but negative for PR. There was a significant association between ER and the histological subtypes (p = 0.042) while no significant association was found between PR expression and histological subtypes (p = 0.650). No significant association was found between hormone receptor status, age and stage of the EOC. Conclusion: The study showed a lower ER expression in serous carcinoma compared to large cohorts from developed countries. Future translational studies could be used to determine response of EOC to endocrine therapy. PMID- 29187929 TI - [Role of GeneXpert MTB/RIF test in the screening for pulmonary tuberculosis at the General Referral Provincial Hospital of Bukavu, in the East of the Democratic Republic of the Congo: balance after 10 months of use]. AB - Introduction: In sub-Saharan Africa, diagnostic methods for tuberculosis are inadequate and are essentially based on microscopy. They constitute a real obstacle to the control of tuberculosis. This study aimed to evaluate the performance of GeneXpert MTB/RIF test compared to classical Ziehl-Neelsen staining at the the general referral provincial hospital of Bukavu, in the east of the Democratic Republic of the Congo after 10 months of use. Methods: The results of Ziehl-Neelsen staining and GeneXpert MTB/RIF molecular biology test performed in 452 patients with suspected tuberculosis were collected. This study compares the validity of these different diagnostic tests in the detection of tuberculosis. Results: In the entire group, the frequency of the pulmonary tuberculosis was 16.3%. The positivity rate was significantly higher in GeneXpert MTB/RIF test than in Ziehl-Neelsen staining in the entire group (15.9% vs 9.3%, p = 0.03) and in HIV seropositive patients (52.0% vs 24.0%; p = 0.007). However, the sensitivity of GeneXpert MTB/RIF test compared to that in Ziehl-Neelsen staining wasn't maximum (95.2%). Finally, GeneXpert MTB/RIF test detected rifampicin resistance in 20.8%. Conclusion: This study confirms the superiority of GeneXpert MTB/RIF test compared to Ziehl-Neelsen staining in the detection of tuberculosis and in the prediction of multi-resistance. Its systematic use coupled with Ziehl-Neelsen staining would better control tuberculosis in sub Saharan Africa.

PMID- 29187931 TI - [Diagnostic and evolutionary profile of multiple myeloma in Senegal: monocentric study conducted from 2005 to 2016]. AB - Introduction: Accessibility to innovative multiple myeloma therapies is limited in sub-Saharan Africa. This study aimed to describe the diagnostic and evolutionary features observed during treatment of our patients with myeloma. Methods: We conducted a retrospective, descriptive, analytical study (2005 - 2016) of patients with myeloma included in the study based on International Myeloma Working Group (IMWG) Criteria (2003,2014) at the Hopital Aristide Le Dantec (Senegal). Results: We collected data from 136 medical records (69 men, 67 women) of patients with an average age of 59 years +/- 10.1 years, who were less than 65 years of age in 69.1% of cases. Tell-tale signs included bone pain (96.3%), renal failure (36.8%), infection (23.5%), pathological fracture (17.6%), spinal cord compression (16.9%) and malignant hypercalcaemia (16.2%). Isotopic antiglobulin test showed that anti-IgG could be detected in 61.3% of cases and Kappa in 65% of cases. Patients were classified stage III (59.4%) and I-II (40.6%)of the index staging system. The median survival of patients under conventional traitement (Mephalan-Prednisone: 67.6%, innovative: 5.9%) was 20 months (1-78 months). Survival rates are better in the absence of neurological and infectious complications and for patients with score I-II of the index Staging System. Conclusion: In our study, multiple myeloma was frequently diagnosed before age 65, at advanced stage of tumor mass. Early detection and access to adequate therapies could improve overall survival. PMID- 29187932 TI - [Immature teratoma of the ovary: about a case]. AB - Ovarian teratomas are tumors resulting from pluripotent germ cells. We here describe 3 different types of teratomas: mature, immature and monodermal teratomas. Immature teratoma accounts for less than 1% of ovarian cancers and mainly affects young subjects. We report the case of a 25 year female patient, admitted with abdomino pelvic mass. She underwent ultrasound and a pelvic CT scan followed by conservative treatment based on left annexectomy associated with multiple biopsies. Anatomopathological examination showed immature ovarian teratoma. Patient's treatment was supplemented by a hysterectomy with lumbo aortic curage and omentectomy. We highlight, through this study and review of the literature, the predisposing factors for this type of rare and severe tumor and the radiological features suggesting these rare histological types of ovarian tumors, in order to improve the prognosis and multidisciplinary management of patients.

AB - Strokes are rare but severe accidents during pregnancy and post-partum period. They are responsible for high mortality and morbidity rates. Pre-eclampsia, eclampsia, and strokes are significantly related. Endothelial dysfunction, alteration of brain self-regulation and severe hypertension are, probably, the cause of many strokes in pregnant women and during postpartum period. We report a case of hemorrhagic stroke of the brainstem in a nonmonitored 21-year old patient at 38 weeks pregnant admitted with severe preeclampsia complicated by eclampsia and then by haemorrhagic stroke of the brainstem on the second post-operative day after cesarean section performed due to suspicion of retroplacental haematoma arisen since her admission. Intracerebral hemorrhage is a rare but severe complication in post-partum women. Several studies are underway to fill the gaps of knowledge involved in the management of pre-eclamptic patients with neurological complications. PMID- 29187934 TI - [Persistence of the 5th aortic arch associated with interruption of the aortic arch]. AB - We report a case of persistence of the 5th aortic arch associated with total interruption of the aortic arch. This clinical case shows the diagnostic pitfall of the persistence of the 5th aortic arch and its beneficial hemodynamic effect. Preoperative clinical picture was misleading, due to the persistence of femoral pulses and clinical signs of left-to-right shunt via a wide ductus arteriosus. The diagnosis was intraoperatively adjusted on the basis of blood pressure monitoring using catheter placed into the femoral artery. PMID- 29187936 TI - Mucin expression patterns in histological grades of colonic cancers in Ghanaian population. AB - Introduction: Myriad roles of mucins in normal tissues have been well documented, including lubrication of the epithelial surfaces; protection from physical damage; facilitation in cell-cell signaling and suppression of inflammatory activity. Pathological expression of mucins has been noted in cancer development and progression. This study sought to identify and quantify the types of mucins produced during various histological grades of colon cancer and to assess the diagnostic significance. Methods: Formalin fixed, paraffin-embedded tissue blocks, comprising three (3) normal colon and twenty-two (22) colon cancer tissues, were retrieved from the archives of the histopathology department of the Komfo Anokye Teaching Hospital. They were stained with Haematoxylin and eosin (H&E) for diagnosis and grading of tumours. Tissues were pre-digested with diastase and stained with Alcian blue (pH 2.5)/Periodic Acid Schiff to characterize the mucin variants present. Results: Our findings indicated that normal colonic tissues expressed exceptionally high amount of acid mucin and low amount of neutral mucin. However, there was a general decrease in mucin expression in colon cancers compared to normal colon tissues. Additional findings suggested that as cancer progresses from low grade to high grade of adenocarcinoma of the colon, there was generally a considerable decrease in the acid mucin production and an increase in the neutral mucin expression. In contrast, a sizeable subpopulation of high-grade adenocarcinomas of colon showed a rather opposite mucin expression pattern- increase in acid mucin and a decrease in neutral mucin. Conclusion: As colonic cancer progresses, there are corresponding changes in the mucin types and content such that there are decrease in acid mucin and increase in neutral mucin expressions. PMID- 29187937 TI - Safety culture in the maternity unit of hospitals in Ilam province, Iran: a census survey using HSOPSC tool. AB - Introduction: Improving quality of maternal care as well as patients' safety are two important issues in health-care service. Therefore, this study aimed to assess the culture of patient safety at maternity units. Methods: This cross sectional study was conducted among staffs working at maternity units in seven hospitals of Ilam city, Iran. The staffs included in this study were gynecologists and midwifes working in different positions including matron, supervisors, head of departments and staffs. Data were collected using the Hospital Survey on Patient Safety Culture (HSOPSC). Results: This study indicated that 59.1% of participants reported fair level of overall perceptions of safety and 67.1% declared that no event was reported during the past 12 months. The most positively perceived dimension of safety culture was teamwork within departments in view of managers (79.41) and personnel (81.10). However, the least positively perceived dimensions of safety culture was staffing levels. Conclusion: The current study revealed areas of strength (teamwork within departments) and weakness (staffing, punitive responses to error) among managers and personnel. In addition, we found that staffs in Ilam's hospitals accept the patient safety culture in maternity units, but, still are far away from excellent culture of patient safety. Therefore, it is necessary to promote culture of patient's safety among professions working in the maternity units of Ilam's hospitals.

This infection can cause severe illness when the organism is contracted congenitally or when it is reactivated in immunosuppressed people. In this paper we review for the first time prevalence and risk factors of T. gondii among pregnant women and HIV-infected adults in Morocco. A systematic review methodology was used to consult three databases: Pub Med, Science Direct and Google Scholar dated until 2015, regarding prevalence data and risk factors of infection among pregnant women and people living with HIV. Data collection and eligibility criteria were established in this paper. No statistical method was employed in this study. Our review resulted in a total of 6 publications meeting the inclusion criteria of prevalence and risk factors of toxoplasmosis in Morocco. Seropositive rates of T. gondii infection reach up to 51% in pregnant women. Risk factors that were reported included contact with soil, lack of knowledge about toxoplasmosis, and a low educational level. For HIV-infected adults, the limited data show a 62.1% prevalence rate of T. gondii .According to our review, there is still very little information on toxoplasmosis disease in pregnant women and HIV infected patients in Morocco. Further research on toxoplasmosis is needed to better ascertain the human disease burden in Morocco.

AB - Introduction: Previous studies about the relationship between tumor recurrence and NRAMP1 and HGPX1 gene polymorphism in patients with non-muscle-invasive bladder cancer (NMIBC) showed inconsistent results. Methods: We conducted a systematic review of the literature on the basis of data from PubMed and China National Knowledge Infrastructure. According to the predefined selection criteria, the eligibility criteria for the studies found in the literature were assessed by two independent authors. The basic characteristics of the included studies and of data relevant to the meta-analysis were extracted. Patients? survival without recurrence was selected as the measure of effect of meta analysis. Results: Four publications were retained. Three studies evaluated the NRAMP1 D534N and three the hGPX1 Pro168Leu. Depending on the association between NRAMP1 D534N and tumor recurrence, the meta-analysis revealed no significant heterogeneity and the combined effect was 3.28 [1.77, 6.11]. Depending on the association between hGPX1 Pro198Leu and tumor recurrence, the meta-analysis showed significant heterogeneity and the combined effect was 1.12 [0.45, 2.77]. Publication bias was uncertain, due to the limited number of included studies.The instability of the combined effects was reported. Conclusion: Very little data are available on the association between tumor recurrence and NRAMP1 D534N and hGPX1 Pro168Leu poolymorphisms in patients with NMIBC. The NRAMP1 D534N could increase the risk of recurrence, but hGPX1 Pro168Leu effect is not clear. A more thorough investigation should be conducted on a larger sample size in order to better explain this phenomenon. PMID- 29187940 TI - Unusual case of ruptured sinus of valsalva aneurysm in a pregnant woman. AB - Sinus of Valsalva aneurysms are extremely rare, and usually of a congenital nature. There are few documented cases of this condition during pregnancy, which renders unclear the therapeutic options. We here report the case of a 26 years old pregnant woman who was referred to our cardiac center for the evaluation of a heart murmur. The two-dimensional transthoracic echocardiography allowed quickly to establishthe diagnosis of a ruptured sinus of Valsalva aneurysm into the right ventricle. A successful surgical correction of the ruptured aneurysm was performed with patch repair. PMID- 29187941 TI - [Accidents of the everyday life (AcVC) in children in Dakar: about 201 cases]. AB - Accidents of everyday life (AcVC) are common in children and can led to disabling injuries and death. This study aimed to analyze the epidemiological aspects of AcVC and the related injury mechanisms in Dakar. We conducted a descriptive, cross-sectional study conducted from 1 January 2013 to 30 June 2013. All the children victims of domestic accidents, sport and leisure accidents or school accidents were included. We studied some general parameters and some parameters related to each type of AcVC. Two hundred and one children were included, accounting for 27% of emergency consultations. There were 148 boys and 53 girls. Children less than 5 years of age were most affected (37.8%). Football and wrestling game were the main causes of AcVC. AcVC occur mainly at home (58.2%) and in the areas of sport and recreation (31.8%). The fractures predominated in the different types of AcVC: 54.9% of domestic accidents, 68.8% of sport and recreation accidents and 40% of school accidents. From an epidemiological perspective, our results are superimposable to literature. Fractures predominated contrary to literature where bruises were preponderant. Wrestling game is the main cause of these fractures, after football. The acquisition of knowledge about the epidemiological aspects of AcVC and the related injury mechanisms will allow for prevention campaigns in Dakar. PMID- 29187942 TI - [Double aortic arch: about two cases]. AB - Double aortic arch is a rare anomaly of the aortic arch. It is due to the absence of involution of the caudal dorsal aorta. The disease usually begins to show itself in very early clinical signs, already detectable in the neonatal period. Angiography is of great interest to its diagnosis as well as to the choice of the therapeutic approach. Only surgical treatment allows to eliminate tracheoesophageal compression. Surgical mortality rate is low thanks to the progress of postoperative resuscitation. We here report two cases of double aortic arch in order to highlight the contribution of imaging in the difficult diagnosis of this anomaly. PMID- 29187943 TI - [Rare digestive tumors: gastrointestinal stromal tumors (GISTs): about a case of small bowel location and literature review]. AB - Gastrointestinal stromal tumors (GISTs) are a rare group of mesenchymal tumors mainly occurring in the gastrointestinal tract. Previously, GISTs were classified as smooth muscle tumors also known as leiomyomas, leiomyosarcomas or leiomyoblastomas. However, since the advent of immunohistochemistry, GISTs have been diagnosed on the basis of the identification of c-kit-positive cells. We here report a case of stromal tumor of the small intestine in order to analyze it in the light of literature data and imaging results, which may suggest prebiopsy diagnosis as well as its therapeutic and prognostic peculiarities. PMID- 29187944 TI - Improving access to HbA1c in sub-Saharan Africa (IA3) cohort: cohort profile. AB - Introduction: Glycated haemoglobin (HbA1c) is the best surrogate of average blood glucose control in diabetic patients, and lowering HbA1c significantly reduces diabetes complications. Moreover, immediate feedback of HbA1c measurement to patients may improve control. However, HbA1c is unavailable in most parts of Africa, a continent with one of the highest burden of diabetes. To translate these evidences, we are conducting a multicentric project in 10 health care facilities in Guinea and Cameroon to evaluate the feasibility and one-year benefit of affordable HbA1c measurement with immediate feedback to patients on diabetes control and related outcomes. Participants: We consecutively enrolled patients with diabetes mellitus independently of the type of disease. We hypothesised an average 1%-decrease in HbA1c in a 1000-patient study population, with a 20% increase in the number of patients reaching treatment goals within 12 months of intervention and follow-up. Findings to date: A total of 1, 349 diabetic patients aged 56.2+/-12.6 years are enrolled (813 in Cameroon and 536 in Guinea) of whom 59.8% are women. The mean duration of diabetes is 7.4+/-6.3 years and baseline HbA1c is 9.7+/-2.6% in Guinea and 8.6+/-2.5% in Cameroon. Future plans: To investigate whether the introduction of routine HbA1c measurement with immediate feedback to patients and provision of relevant education would improve diabetes control after one year. The impact of the intervention on diabetes associated-complications and mortality warrant further assessment in the long term. PMID- 29187945 TI - Association between mean platelet volume and severity of rheumatoid arthritis. AB - Introduction: In recent years, it is suggested that platelet histogram indices, such as mean platelet volume (MPV) may be related to the activity of rheumatoid arthritis (RA). The aim of this study was to assess relationship between MPV and activity of rheumatoid arthritis. Methods: Sixty consecutive patients fulfilling the American College of Rheumatology (ACR) criteria for RA were recruited from the rheumatology outpatient clinics in Semnan, Iran. Current disease activity score (DAS-28 score) was assessed at baseline, 2 months and 4 months after the admission time and beginning of the treatment schedule. Complete blood count (including MPV), C-reactive protein (CRP) and ESR were measured in each visit. MPV was analyzed by the Cell Dyne 3500 automated blood cell counter. Results: There was a significant reduction in DAS-28 score within 4 months of total assessment (from 4.47 +/- 2.24 versus 3.18 +/- 1.55) (p < 0.001). There was no significant difference in MPV levels at the three study time points. No significant correlations were observed between the DAS-28 score and mean MPV levels at the same time points. The rate of positive CRP was decreased within the same period (p = 0.002); however, the trend of the changes in other laboratory parameters including MPV, platelet count and ESR values was not significant. The measurement of MPV value did not correlate with disease activity in RA patients within 4 months of treatment scheduling. Conclusion: Although therapeutic regimens, which improve RA manifestations, can reduce RA activity, they had no effect on MPV during this time period. It seems MPV may not be able to predict disease activity in RA patients. PMID- 29187947 TI - Macroprolactinemia and Empty Sella Syndrome. AB - Macroprolactinemia is a polymeric form of prolactin-release, causing mildly symptomatic clinical pictures. The former can be isolated or associated with other causes of hyperprolactinemia. The association with an empty sella syndrome is rare. We report a case of a female patient discovered with this association. It's about a female patient 47 years old, followed up since the age of 31 years for bilateral galactorrhea and a spaniomenorrhea. There has been no associated drug intake. Her exploration has showed a serum prolactin level of 635 mIU/L. Thyroid test results were normal T4 = 10,2ng/L and TSH = 1.76 mIU/L. A brain scan has showed an empty sella turcica. Despite the unchanged levels of prolactinemia, the evolution under dopaminergic 5 mg /D has been marked by the occurrence of a pregnancy with persistent moderate hyperprolactinemia in the postpartum. Chromatography has showed a predominance of the macroprolactin form with: Prolactin monomer at 4.8%, Big Prolactin at 5% and Big Big Prolactin at 83%, thus stopping bromocriptine. Our observation suggests that macroprolactinemia can be associated with conventional etiologies of moderate hyperprolactinemia as the empty sella syndrome. Its detection would prevent the use of dopaminergic therapy which seems not useful. PMID- 29187948 TI - Nutritional status, weight perception and weight control practices among office employees in Sokoto, Nigeria. AB - Introduction: Overweight and obesity have become the fifth leading risk for global deaths. Office employees have been identified as a high risk group due to the sedentary nature of their work, and accurate weight perception is believed to be critical to acceptance of weight control interventions. This study was conducted to assess the nutritional status, weight perception and weight control practices of office employees in Sokoto, Nigeria. Methods: A cross sectional study was conducted among 285 randomly selected office employees in private establishments in Sokoto, Nigeria, in February and March 2013. Anthropometry was done for the participants in addition to questionnaire administration. Results: The mean age of the participants was 33.08 +/- 7.23 years, they were predominantly males (56.5%) and married (57.5%). None was underweight, 111 (38.9%) had normal weight, 105 (36.8%) were overweight and 69 (24.2%) were obese. Among the participants with normal weight, overweight and obesity, 71.2%, 35.2% and 58.0% respectively accurately perceived their weight; while 28.8%, 50.5% and 30.4% respectively underestimated their weight. There was poor agreement between actual and perceived weight (k statistics = 0.341, p < 0.001). Only 67 (23.5%) of the 285 participants were engaged in weight control practices. Conclusion: This study showed high prevalence of overweight and obesity, weight misperceptions, and poor uptake of weight control practices among office employees in Sokoto, Nigeria. These findings underscore the need for a holistic approach to obesity control interventions that encompasses both body image perception and nutritional assessment. PMID- 29187946 TI - The endoscopic endonasal approach to cranio-cervical junction: the complete panel. AB - We aim to establish a complete summary on the Endoscopic Endonasal Approach (EEA) to Cranio Cervical Junction (CCJ): evolution since first description, criteria to predict the feasibility and limitations, anatomical landmarks, indications and biomechanical evaluation after performing the approach. A comprehensive literature search to identify all available literature published between March 2002 and June 2015, the articles were divided into four categories according to their main purpose: 1- surgical technique, 2- anatomical landmarks and limitations, 3- literature reviews to identify main indications, 4- biomechanical studies. Thereafter, we demonstrate the approach step-by-step, using 1 fresh and 3 silicon injected embalmed cadaveric specimen heads. 61 articles and one poster were identified. The approach was first described on cadaveric study in 2002, and firstly used to perform odontoidectomy in 2005. The main indication is odontoid rheumatoid pannus and basilar invagination. The nasopalatine line (NPL), the superior nostril-hard palate Line (SN-HP), the naso-axial line (NAxL), the rhinopalatine Line (RPL) and other methods were described to predict the anatomical feasibility of the approach. The craniocervical fusion is potentially unnecessary after removal of < 75% of one occipital condyle. A recent cadaveric study stated the possibility of C1-C2 fusion via EEA. This paper reviews all available clinical and anatomical studies on the EEA to CCJ. The approach marked a significant evolution since its first description in 2002. Because of its lesser complications compared to the transoral approach, the EEA became when feasible, the approach of choice to the ventral CCJ. PMID- 29187949 TI - Knowledge and perceptions of health and environmental risks related to artisanal gold mining by the artisanal miners in Burkina Faso: a cross-sectional survey. AB - Introduction: Artisanal gold mining is an activity ensuring the survival of about 700,000 families in Burkina Faso with a considerable contribution to the national economy. Techniques and chemicals used in the operation, have adverse impacts on health and the environment. Our study aims to evaluate the perceptions and knowledge of these different impacts among artisanal gold miners. Methods: A cross-sectional survey was conducted in artisanal gold mines Bouda and Nagsene in the region of the North of Burkina Faso. Two hundred miners over 18 years of age were interviewed. Results: All the participants have recognized that gold mining has health impacts and 88.5% felt these impacts as important with a significantly higher proportion among those with more than 3 years' seniority (p = 0.001). The environmental impacts were perceived as important by 64.5% of miners, with a significant difference according to the position (p = 0.004). Sixty percent (60%) of respondents could identify at least 3 of the 5 health impacts of gold mining listed and 49.5% acknowledged at least 3 impacts on the environment. The diggers had significantly more knowledge about the symptoms (p < 0.001). Conclusion: Study highlights the lack of knowledge of the Stampeders on the health and environmental impacts of artisanal gold mining. Findings might be used to develop more effective awareness campaigns in the future. Communication with diggers must focus on the risk perception because it appears that raising risk perceptions from low to high would have a major effect on behavior. PMID- 29187951 TI - Profiling study of the major and minor components of kaffir lime oil (Citrus hystrix DC.) in the fractional distillation process. AB - Introduction: Essential oil is consisting of complex component. It is divided into major and minor component. Therefore, this study aims to examine the distribution of major and minor components on Kaffir lime oil by using fractional distillation. Fractional distillation and distributional analysis of components within fractions have been performed on kaffir lime oil (Citrus hystrix DC.). Methods: Fractional distillation was performed by using PiloDist 104-VTU, column length of 2 m (number of plate 120), the system pressure was set on 5 and 10 mBar, while the reflux ratio varied on 10/10, 20/10 and 60/10, and the chemical composition analysis was done by using GC-MS. Chemical composition of the distillated lime oil consisted of mix-twigs and leaves that composed of 20 compounds, with five main components beta-citronellal (46.40%), L-linalool (13.11%), beta-citronellol (11.03%), citronelyl acetate (6.76%) and sabinen (5.91%). Results: The optimum conditions for fractional distillation were obtained at 5 mBar pressure with reflux ratio of 10/10. Components of beta citronellal and L-linalool were distributed in the fraction-1 to fraction 9, hydrocarbon monoterpenes components were distributed only on the fraction-1 to fraction 4, while the oxygenated monoterpenes components dominated the fraction-5 to fraction-9. Conclusion: The highest level of beta-citronellal was 84.86% (fraction-7), L-linalool 20.13% (fraction-5), sabinen 19.83% (fraction-1), and the component level of 4-terpeneol, beta-citronellol and sitronelyl acetate respectively 7.16%; 12.27%; 5.22% (fraction-9). PMID- 29187950 TI - Assessment of methicillin resistant Staphylococcus Aureus detection methods: analytical comparative study. AB - Introduction: The heterogeneous expression of methicillin resistance in Staphylococcus aureus (MRSA) affects the efficiency of tests available to detect it. The objective of this study was to assess four phenotypic tests used to detect MRSA. Methods: This is an analytical comparative study conducted among sudanese patients during period from May 2012 to July 2014, Staphylococcus aureus strains were isolated and identified by conventional methods, and then confirmed by PCR detection of coagulase gene. PCR detection of mecA gene was used as a gold standard to assess oxacillin resistance screen agar base (ORSAB), oxacillin disc, cefoxitin disc (at different temperatures and incubation periods) and MRSA-latex agglutination test. S.aureus ATCC 25923 was used as control. Sensitivity and specificity were calculated. Results: MRSA- latex agglutination was the most accurate test; it showed 100% of both sensitivity and specificity, followed by cefoxitin disc with sensitivity of 98.48% and specificity of 100%. However, both of oxacillin disc and oxacillin resistance screen agar base showed less accurate results, and were affected by incubation periods. Oxacillin disc after 24 h incubation both at 30 degrees C and 35 degrees C showed sensitivity and specificity values of 87.88% and 96.23%, respectively. However, after 48h incubation the test at 30 degrees C showed sensitivity and specificity values of 89.39%, and 94.34%, respectively. At 35 degrees C (48h) it showed values of 89.39%, 92.45% respectively. Specificity of ORSAB was more than oxacillin disc at 35 degrees C after 24h incubation 98.11% and 96.23%, respectively. Conclusion: MRSA- latex agglutination and cefoxitin disc diffusion tests are recommended for routine detection of MRSA. PMID- 29187952 TI - Solid pseudopapillary neoplasm of the pancreas in two male patients: gender does not matter. AB - Solid pseudopapillary tumour (SPT) is an unusual pancreatic neoplasm which predominantly affects young women. Less than 10% of patients with SPT in the reported literature were male. In this paper, the authors report two new cases of SPT that occurred in two male patients aged respectively 25 and 20 years old. Abdominal computed tomography scan showed a well-defined heterogeneous mass involving respectively the tail and the body of the pancreas with peripheral calcifications in the first case. The two patients underwent distal splenopancreatectomy. Histopathological examination of the surgical specimen coupled with immunohistochemical study was compatible with solid pseudopapillary tumour. On postoperative day 8, the first patient developed abdominal wall abscess and peritoneal collection. Postoperative course was uneventful for the second patient. In summary, a large, well-encapsulated cystic mass in the pancreas of a young man should raise suspicion of solid pseudopapillary tumour. PMID- 29187953 TI - Seasonal distribution and faunistic of ticks in the Alashtar county (Lorestan Province), Iran. AB - Introduction: Ticks are non-permanent obligate parasites that have considerable medical-veterinary and zoonosis importance. In this regard a study designed to investigate the distribution and fauna of ticks in the Alashtar county in Iran from April and March 2014. Methods: Ticks were collected from livestock farms and facilities from selected rural and geographically location in the Alashtar county. Based morphological characteristics and reference identification keys, ticks were identified. Results: A total of 549 ticks including 411 hard and 138 soft ticks were found. Ten tick species including Haemaphysalis concinna (0.36%), Haemaphysalis sulcata (0.36%), Hyalomma anatolicum (0.18%), Hyalomma dromedarii (0.18%), Hyalomma marginatum (1.45 %), Hyalomma schulzei (0.36%), Rhipicephalus annulatus (0.18%), Rhipicephalus bursa (28.1%), Rhipicephalus sanguineus (43.63%) and Argas persicus (25.2%) were identified. Tick seasonal distribution were 47.26%, 22.63%, 14.96% and 15.15% in the spring, summer, autumn and winter, respectively. The tick distribution was more from plain areas (64.96%) than the mountainous areas (35.04%). The rates of the tick contamination were 97.3% and 2.7% in the traditional and industrial livestock's, respectively. The livestock contamination ranks to the hard ticks were cattle (39.51%), sheep (34.15%) and goats (26.34 %), respectively. Chi-square analysis showed a significant difference among the seasonal distribution of the ticks in the spring, summer and autumn or winter; between the tick distribution in the plain and mountainous areas; and between the traditional and industrial livestock's tick contamination (P < 0.05). Conclusion: Present study proves to change the traditional livestock's to the industrial livestock's. These findings highlight the importance of ticks and shows need to their control and tick pest management. PMID- 29187955 TI - Duodenal diverticulitis: a difficult clinical problem. PMID- 29187954 TI - Application of psychosocial models to Home-Based Testing and Counseling (HBTC) for increased uptake and household coverage in a large informal urban settlement in Kenya. AB - Introduction: Home Based Testing and Counselling (HBTC) aims at reaching individuals who have low HIV risk perception and experience barriers which prevent them from seeking HIV testing and counseling (HTC) services. Saturating the community with HTC is needed to achieve the ambitious 90-90-90 targets of knowledge of HIV status, ARV treatment and viral suppression. This paper describes the use of health belief model and community participation principles in HBTC to achieve increased household coverage and HTC uptake. Methods: This cross sectional survey was done between August 2009 and April 2011 in Kibera slums, Nairobi city. Using three community participation principles; defining and mobilizing the community, involving the community, overcoming barriers and respect to cultural differences and four constructs of the health belief model; risk perception, perceived severity, perceived benefits of changed behavior and perceived barriers; we offered HTC services to the participants. Descriptive statistics were used to describe socio-demographic characteristics, calculate uptake and HIV prevalence. Results: There were 72,577 individuals enumerated at the start of the program; 75,141 residents were found during service delivery. Of those, 71,925 (95.7%) consented to participate, out of which 71,720 (99.7%) took the HIV test. First time testers were (39%). The HIV prevalence was higher (6.4%) among repeat testers than first time testers (4.0%) with more women (7.4%) testing positive than men (3.6%) and an overall 5.5% slum prevalence. Conclusion: This methodology demonstrates that the use of community participation principles combined with a psychosocial model achieved high HTC uptake, coverage and diagnosed HIV in individuals who believed they are HIV free. This novel approach provides baseline for measuring HTC coverage in a community. PMID- 29187956 TI - [Leg ulcer revealing cutaneous leishmaniasis]. AB - Leishmaniases are parasitic diseases occurring in endemic tropical and subtropical areas and caused by protozoa of the genus leishmania, transmitted by a diptera (sand fly). We here report a case of topical cutaneous leishmaniasis discovered in a 15-year old boy with painless ulcer on his left leg, who had been staying in South Africa. Clinical examination showed painless non-itchy ulcer, occurred 1 month before, on the antero-internal part of his left leg with crusts and scars caused by insect bites, all evolving in a context of patient's general health status, without mucosal or visceral lesions. Skin biopsy allowed specific parasitologic diagnosis revealing topical zoonotic cutaneous leishmaniasis caused by L. major. The patient underwent topical treatment based on paramomycin and oral fluconazole resulting in ulcer healing at the end of 2 months. PMID- 29187957 TI - Cricopharyngeal bar. PMID- 29187958 TI - Giving the Underdog a Leg Up: A Counternarrative of Nonviolent Resistance Improves Sustained Third-Party Support of a Disempowered Group. AB - In the current work, we experimentally examined the effect of exposure to a narrative of nonviolent resistance on third-party attitudes toward and support for a disempowered group involved in asymmetric conflict. Across three experiments, we found that Americans exposed to a brief video about Palestinian nonviolent resistance consistently registered more favorable attitudes toward Palestinians than people who watched a film trailer either unrelated to the Israeli-Palestinian conflict or a trailer to a Palestinian-made film about sympathetic Palestinians violently opposing Israelis. Americans' attitudes toward Palestinians and behavior supporting Palestinian collective action persisted weeks after exposure to nonviolent resistance and were mediated by decreased perceptions that Palestinians are inherently violent. Importantly, positive attitudes toward Palestinians did not result in increased negativity toward Israelis. These data show that exposure to nonviolent resistance can have lasting effects on third-party attitudes and behavior toward an underdog/disempowered group, without driving partisanship. PMID- 29187959 TI - Frankly, We Do Give a Damn: The Relationship Between Profanity and Honesty. AB - There are two conflicting perspectives regarding the relationship between profanity and dishonesty. These two forms of norm-violating behavior share common causes and are often considered to be positively related. On the other hand, however, profanity is often used to express one's genuine feelings and could therefore be negatively related to dishonesty. In three studies, we explored the relationship between profanity and honesty. We examined profanity and honesty first with profanity behavior and lying on a scale in the lab (Study 1; N = 276), then with a linguistic analysis of real-life social interactions on Facebook (Study 2; N = 73,789), and finally with profanity and integrity indexes for the aggregate level of U.S. states (Study 3; N = 50 states). We found a consistent positive relationship between profanity and honesty; profanity was associated with less lying and deception at the individual level and with higher integrity at the society level. PMID- 29187960 TI - Meta-analysis of Liver and Heart Transcriptomic Data for Functional Annotation Transfer in Mammalian Orthologs. AB - Functional annotation transfer across multi-gene family orthologs can lead to functional misannotations. We hypothesised that co-expression network will help predict functional orthologs amongst complex homologous gene families. To explore the use of transcriptomic data available in public domain to identify functionally equivalent ones from all predicted orthologs, we collected genome wide expression data in mouse and rat liver from over 1500 experiments with varied treatments. We used a hyper-graph clustering method to identify clusters of orthologous genes co-expressed in both mouse and rat. We validated these clusters by analysing expression profiles in each species separately, and demonstrating a high overlap. We then focused on genes in 18 homology groups with one-to-many or many-to-many relationships between two species, to discriminate between functionally equivalent and non-equivalent orthologs. Finally, we further applied our method by collecting heart transcriptomic data (over 1400 experiments) in rat and mouse to validate the method in an independent tissue. PMID- 29187961 TI - Host size influences the effects of four isolates of an amphibian chytrid fungus. AB - Understanding factors that influence host-pathogen interactions is key to predicting outbreaks in natural systems experiencing environmental change. Many amphibian population declines have been attributed to an amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd). While this fungus is widespread, not all Bd-positive populations have been associated with declines, which could be attributed to differences in pathogen virulence or host susceptibility. In a laboratory experiment, we examined the effects of Bd isolate origin, two from areas with Bd-associated amphibian population declines (El Cope, Panama, and California, USA) and two from areas without Bd-related population declines (Ohio and Maine, USA), on the terrestrial growth and survival of American toad (Anaxyrus americanus) metamorphs reared in larval environments with low or high intraspecific density. We predicted that (1) Bd isolates from areas experiencing declines would have greater negative effects than Bd isolates from areas without declines, and (2) across all isolates, growth and survival of smaller toads from high-density larval conditions would be reduced by Bd exposure compared to larger toads from low-density larval conditions. Our results showed that terrestrial survival was reduced for smaller toads exposed to Bd with variation in the response to different isolates, suggesting that smaller size increased susceptibility to Bd. Toads exposed to Bd gained less mass, which varied by isolate. Bd isolates from areas with population declines, however, did not have more negative effects than isolates from areas without recorded declines. Most strikingly, our study supports that host condition, measured by size, can be indicative of the negative effects of Bd exposure. Further, Bd isolates' impact may vary in ways not predictable from place of origin or occurrence of disease related population declines. This research suggests that amphibian populations outside of areas experiencing Bd-associated declines could be impacted by this pathogen and that the size of individuals could influence the magnitude of Bd's impact. PMID- 29187962 TI - Landscape-scale genetic differentiation of a mycangial fungus associated with the ambrosia beetle, Xylosandrus germanus (Blandford) (Curculionidae:Scolytinae) in Japan. AB - In this study, we examined the genetic structures of the ambrosia fungus isolated from mycangia of the scolytine beetle, Xylosandrus germanus to understand their co-evolutionary relationships. We analyzed datasets of three ambrosia fungus loci (18S rDNA, 28S rDNA, and the beta-tubulin gene) and a X. germanus locus dataset (cytochrome c oxidase subunit 1 (COI) mitochondrial DNA). The ambrosia fungi were separated into three cultural morphptypes, and their haplotypes were distinguished by phylogenetic analysis on the basis of the three loci. The COI phylogenetic analysis revealed three distinct genetic lineages (clades A, B, and C) within X. germanus, each of which corresponded to specific ambrosia fungus cultural morphptypes. The fungal symbiont phylogeny was not concordant with that of the beetle. Our results suggest that X. germanus may be unable to exchange its mycangial fungi, but extraordinary horizontal transmission of symbiotic fungi between the beetle's lineages occurred at least once during the evolutionary history of this symbiosis. PMID- 29187963 TI - Environmental correlates of internal coloration in frogs vary throughout space and lineages. AB - Internal organs of ectotherms have melanin-containing cells that confer different degrees of coloration to them. Previous experimental studies analyzed their developmental origin, role in immunity, and hormonal regulation. For example, melanin increases with ultraviolet radiation (UV) and temperature in frogs and fish. However, little is known about how environmental variables influence the amount of coloration on organs among amphibian species over a large spatial extent. Here, we tested how climatic variables (temperature, UV, and photoperiod) influence the coloration of internal organs of anurans. We recorded the level of melanin pigmentation using four categories on 12 internal organs and structures of 388 specimens from 43 species belonging to six anuran families. Then, we tested which climatic variables had the highest covariation with the pigmentation on each organ after controlling for spatial autocorrelation in climatic variables and phylogenetic signal in organ coloration using the extended version of the RLQ ordination. Coloration in all organs was correlated with the phylogeny. However, the coloration of different organs was affected by different variables. Specifically, the coloration of the heart, kidneys, and rectum of hylids, Rhinella schneideri, some Leptodactylus, and Proceratophrys strongly covaried with temperature and photoperiod, whereas that of the testicle, lumbar parietal peritoneum, lungs, and mesenterium of Leiuperinae, Hylodidae, Adenomera, and most Leptodactylus had highest covariation with UV-B and temperature. Our results support the notion that melanin pigmentation on the surface of organs of amphibians has an adaptive function conferred by the protective functions of the pigment. But most importantly, internal melanin seems to respond differently to climatic variables depending on the lineage and locality in which species occur. PMID- 29187964 TI - Population structure and connectivity of the mountainous star coral, Orbicella faveolata, throughout the wider Caribbean region. AB - As coral reefs continue to decline worldwide, it becomes ever more necessary to understand the connectivity between coral populations to develop efficient management strategies facilitating survival and adaptation of coral reefs in the future. Orbicella faveolata is one of the most important reef-building corals in the Caribbean and has recently experienced severe population reductions. Here, we utilize a panel of nine microsatellite loci to evaluate the genetic structure of O. faveolata and to infer connectivity across ten sites spanning the wider Caribbean region. Populations are generally well-mixed throughout the basin (FST = 0.038), although notable patterns of substructure arise at local and regional scales. Eastern and western populations appear segregated with a genetic break around the Mona Passage in the north, as has been shown previously in other species; however, we find evidence for significant connectivity between Curacao and Mexico, suggesting that the southern margin of this barrier is permeable to dispersal. Our results also identify a strong genetic break within the Mesoamerican Barrier Reef System associated with complex oceanographic patterns that promote larval retention in southern Belize. Additionally, the diverse genetic signature at Flower Garden Banks suggests its possible function as a downstream genetic sink. The findings reported here are relevant to the ongoing conservation efforts for this important and threatened species, and contribute to the growing understanding of large-scale coral reef connectivity throughout the wider Caribbean. PMID- 29187965 TI - The role of species-specific sensory cues in male responses to mating rivals in Drosophila melanogaster fruitflies. AB - Complex sets of cues can be important in recognizing and responding to conspecific mating competitors and avoiding potentially costly heterospecific competitive interactions. Within Drosophila melanogaster, males can detect sensory inputs from conspecifics to assess the level of competition. They respond to rivals by significantly extending mating duration and gain significant fitness benefits from doing so. Here, we tested the idea that the multiple sensory cues used by D. melanogaster males to detect conspecifics also function to minimize "off-target" responses to heterospecific males that they might encounter (Drosophila simulans, Drosophila yakuba, Drosophila pseudoobscura, or Drosophila virilis). Focal D. melanogaster males exposed to D. simulans or D. pseudoobscura subsequently increased mating duration, but to a lesser extent than following exposure to conspecific rivals. The magnitude of rivals' responses expressed by D. melanogaster males did not align with genetic distance between species, and none of the sensory manipulations caused D. melanogaster to respond to males of all other species tested. However, when we removed or provided "false" sensory cues, D. melanogaster males became more likely to show increased mating duration responses to heterospecific males. We suggest that benefits of avoiding inaccurate assessment of the competitive environment may shape the evolution of recognition cues. PMID- 29187966 TI - Changing measurements or changing movements? Sampling scale and movement model identifiability across generations of biologging technology. AB - Animal movement patterns contribute to our understanding of variation in breeding success and survival of individuals, and the implications for population dynamics. Over time, sensor technology for measuring movement patterns has improved. Although older technologies may be rendered obsolete, the existing data are still valuable, especially if new and old data can be compared to test whether a behavior has changed over time. We used simulated data to assess the ability to quantify and correctly identify patterns of seabird flight lengths under observational regimes used in successive generations of wet/dry logging technology. Care must be taken when comparing data collected at differing timescales, even when using inference procedures that incorporate the observational process, as model selection and parameter estimation may be biased. In practice, comparisons may only be valid when degrading all data to match the lowest resolution in a set. Changes in tracking technology, such as the wet/dry loggers explored here, that lead to aggregation of measurements at different temporal scales make comparisons challenging. We therefore urge ecologists to use synthetic data to assess whether accurate parameter estimation is possible for models comparing disparate data sets before planning experiments and conducting analyses such as responses to environmental changes or the assessment of management actions. PMID- 29187967 TI - Highly contrasted population genetic structures in a host-parasite pair in the Caribbean Sea. AB - Evolution and population genetic structure of marine species across the Caribbean Sea are shaped by two complex factors: the geological history and the present pattern of marine currents. Characterizing and comparing the genetic structures of codistributed species, such as host-parasite associations, allow discriminating the relative importance of environmental factors and life history traits that influenced gene flow and demographic events. Using microsatellite and Cytochrome Oxidase I markers, we investigated if a host-parasite pair (the heart urchin Meoma ventricosa and its parasitic pea crab Dissodactylus primitivus) exhibits comparable population genetic structures in the Caribbean Sea and how the observed patterns match connectivity regions from predictive models and other taxa. Highly contrasting patterns were found: the host showed genetic homogeneity across the whole studied area, whereas the parasite displayed significant differentiation at regional and local scales. The genetic diversity of the parasitic crabs (both in microsatellites and COI) was distributed in two main groups, Panama-Jamaica-St Croix on the one hand, and the South-Eastern Caribbean on the other. At a smaller geographical scale, Panamanian and Jamaican parasite populations were genetically more similar, while more genetic differentiation was found within the Lesser Antilles. Both species showed a signature of population expansion during the Quaternary. Some results match predictive models or data from previous studies (e.g., the Western-Eastern dichotomy in the parasite) while others do not (e.g., genetic differentiation within the Lesser Antilles). The sharp dissimilarity of genetic structure of these codistributed species outlines the importance of population expansion events and/or contrasted patterns of gene flow. This might be linked to differences in several life history traits such as fecundity (higher for the host), swimming capacity of larval stages (higher for the parasite), and habitat availability (higher for the host). PMID- 29187968 TI - The xeric side of the Brazilian Atlantic Forest: The forces shaping phylogeographic structure of cacti. AB - In order to investigate biogeographic influences on xeric biota in the Brazilian Atlantic Forest (BAF), a biodiversity hotspot, we used a monophyletic group including three cactus taxa as a model to perform a phylogeographic study: Cereus fernambucensis subsp. fernambucensis, C. fernambucensis subsp. sericifer, and C. insularis. These cacti are allopatric and grow in xeric habitats along BAF, including isolated granite and gneiss rock outcrops (Inselbergs), sand dune vegetation (Restinga forest), and the rocky shore of an oceanic archipelago (islands of Fernando de Noronha). The nucleotide information from nuclear gene phytochrome C and plastid intergenic spacer trnS-trnG was used to perform different approaches and statistical analyses, comprising population structure, demographic changes, phylogenetic relationships, and biogeographic reconstruction in both spatial and temporal scales. We recovered four allopatric population groups with highly supported branches in the phylogenetic tree with divergence initiated in the middle Pleistocene: southern distribution of C. fernambucensis subsp. fernambucensis, northern distribution of C. fernambucensis subsp. fernambucensis together with C. insularis, southern distribution of C. fernambucensis subsp. sericifer, and northern distribution of C. fernambucensis subsp. sericifer. Further, the results suggest that genetic diversity of population groups was strongly shaped by an initial colonization event from south to north followed by fragmentation. The phylogenetic pattern found for C. insularis is plausible with peripatric speciation in the archipelago of Fernando de Noronha. To explain the phylogeographic patterns, the putative effects of both climatic and sea level changes as well as neotectonic activity during the Pleistocene are discussed. PMID- 29187969 TI - Syntopic frogs reveal different patterns of interaction with the landscape: A comparative landscape genetic study of Pelophylax nigromaculatus and Fejervarya limnocharis from central China. AB - Amphibians are often considered excellent environmental indicator species. Natural and man-made landscape features are known to form effective genetic barriers to amphibian populations; however, amphibians with different characteristics may have different species-landscape interaction patterns. We conducted a comparative landscape genetic analysis of two closely related syntopic frog species from central China, Pelophylax nigromaculatus (PN) and Fejervarya limnocharis (FL). These two species differ in several key life history traits; PN has a larger body size and larger clutch size, and reaches sexual maturity later than FL. Microsatellite DNA data were collected and analyzed using conventional (FST, isolation by distance (IBD), AMOVA) and recently developed (Bayesian assignment test, isolation by resistance) landscape genetic methods. As predicted, a higher level of population structure in FL (FST' = 0.401) than in PN (FST' = 0.354) was detected, in addition to FL displaying strong IBD patterns (r = .861) unlike PN (r = .073). A general north-south break in FL populations was detected, consistent with the IBD pattern, while PN exhibited clustering of northern- and southern-most populations, suggestive of altered dispersal patterns. Species-specific resistant landscape features were also identified, with roads and land cover the main cause of resistance to FL, and elevation the main influence on PN. These different species-landscape interactions can be explained mostly by their life history traits, revealing that closely related and ecologically similar species have different responses to the same landscape features. Comparative landscape genetic studies are important in detecting such differences and refining generalizations about amphibians in monitoring environmental changes. PMID- 29187970 TI - Land use not litter quality is a stronger driver of decomposition in hyperdiverse tropical forest. AB - In hyperdiverse tropical forests, the key drivers of litter decomposition are poorly understood despite its crucial role in facilitating nutrient availability for plants and microbes. Selective logging is a pressing land use with potential for considerable impacts on plant-soil interactions, litter decomposition, and nutrient cycling. Here, in Borneo's tropical rainforests, we test the hypothesis that decomposition is driven by litter quality and that there is a significant "home-field advantage," that is positive interaction between local litter quality and land use. We determined mass loss of leaf litter, collected from selectively logged and old-growth forest, in a fully factorial experimental design, using meshes that either allowed or precluded access by mesofauna. We measured leaf litter chemical composition before and after the experiment. Key soil chemical and biological properties and microclimatic conditions were measured as land-use descriptors. We found that despite substantial differences in litter quality, the main driver of decomposition was land-use type. Whilst inclusion of mesofauna accelerated decomposition, their effect was independent of land use and litter quality. Decomposition of all litters was slower in selectively logged forest than in old-growth forest. However, there was significantly greater loss of nutrients from litter, especially phosphorus, in selectively logged forest. The analyses of several covariates detected minor microclimatic differences between land-use types but no alterations in soil chemical properties or free-living microbial composition. These results demonstrate that selective logging can significantly reduce litter decomposition in tropical rainforest with no evidence of a home-field advantage. We show that loss of key limiting nutrients from litter (P & N) is greater in selectively logged forest. Overall, the findings hint at subtle differences in microclimate overriding litter quality that result in reduced decomposition rates in selectively logged forests and potentially affect biogeochemical nutrient cycling in the long term. PMID- 29187971 TI - Plant diversity has contrasting effects on herbivore and parasitoid abundance in Centaurea jacea flower heads. AB - High biodiversity is known to increase many ecosystem functions, but studies investigating biodiversity effects have more rarely looked at multi-trophic interactions. We studied a tri-trophic system composed of Centaurea jacea (brown knapweed), its flower head-infesting tephritid fruit flies and their hymenopteran parasitoids, in a grassland biodiversity experiment. We aimed to disentangle the importance of direct effects of plant diversity (through changes in apparency and resource availability) from indirect effects (mediated by host plant quality and performance). To do this, we compared insect communities in C. jacea transplants, whose growth was influenced by the surrounding plant communities (and where direct and indirect effects can occur), with potted C. jacea plants, which do not compete with the surrounding plant community (and where only direct effects are possible). Tephritid infestation rate and insect load, mainly of the dominant species Chaetorellia jaceae, decreased with increasing plant species and functional group richness. These effects were not seen in the potted plants and are therefore likely to be mediated by changes in host plant performance and quality. Parasitism rates, mainly of the abundant chalcid wasps Eurytoma compressa and Pteromalus albipennis, increased with plant species or functional group richness in both transplants and potted plants, suggesting that direct effects of plant diversity are most important. The differential effects in transplants and potted plants emphasize the importance of plant-mediated direct and indirect effects for trophic interactions at the community level. The findings also show how plant-plant interactions critically affect results obtained using transplants. More generally, our results indicate that plant biodiversity affects the abundance of higher trophic levels through a variety of different mechanisms. PMID- 29187972 TI - Interactive effects of temperature and habitat complexity on freshwater communities. AB - Warming can lead to increased growth of plants or algae at the base of the food web, which may increase the overall complexity of habitat available for other organisms. Temperature and habitat complexity have both been shown to alter the structure and functioning of communities, but they may also have interactive effects, for example, if the shade provided by additional habitat negates the positive effect of temperature on understory plant or algal growth. This study explored the interactive effects of these two major environmental factors in a manipulative field experiment, by assessing changes in ecosystem functioning (primary production and decomposition) and community structure in the presence and absence of artificial plants along a natural stream temperature gradient of 5 18 degrees C. There was no effect of temperature or habitat complexity on benthic primary production, but epiphytic production increased with temperature in the more complex habitat. Cellulose decomposition rate increased with temperature, but was unaffected by habitat complexity. Macroinvertebrate communities were less similar to each other as temperature increased, while habitat complexity only altered community composition in the coldest streams. There was also an overall increase in macroinvertebrate abundance, body mass, and biomass in the warmest streams, driven by increasing dominance of snails and blackfly larvae. Presence of habitat complexity, however, dampened the strength of this temperature effect on the abundance of macroinvertebrates in the benthos. The interactive effects that were observed suggest that habitat complexity can modify the effects of temperature on important ecosystem functions and community structure, which may alter energy flow through the food web. Given that warming is likely to increase habitat complexity, particularly at higher latitudes, more studies should investigate these two major environmental factors in combination to improve our ability to predict the impacts of future global change. PMID- 29187973 TI - Variation in reproductive isolation across a species range. AB - Reproductive isolation is often variable within species, a phenomenon that while largely ignored by speciation studies, can be leveraged to gain insight into the potential mechanisms driving the evolution of genetic incompatibilities. We used experimental greenhouse crosses to characterize patterns of reproductive isolation among three divergent genetic lineages of Campanulastrum americanum that occur in close geographic proximity in the Appalachian Mountains. Substantial, asymmetrical reproductive isolation for survival due to cytonuclear incompatibility was found among the lineages (up to 94% reduction). Moderate reductions in pollen viability, as well as cytoplasmic male sterility, were also found between some Mountain populations. We then compared these results to previously established patterns of reproductive isolation between these Mountain lineages and a fourth, widespread Western lineage to fully characterize reproductive isolation across the complete geographic and genetic range of C. americanum. Reproductive isolation for survival and pollen viability was consistent across studies, indicating the evolution of the underlying genetic incompatibilities is primarily determined by intrinsic factors. In contrast, reproductive isolation for germination was only found when crossing Mountain populations with the Western lineage, suggesting the underlying genetic incompatibility is likely influenced by environmental or demographic differences between the two lineages. Cytoplasmic male sterility was also limited in occurrence, being restricted to a handful of Mountain populations in a narrow geographic range. These findings illustrate the complexity of speciation by demonstrating multiple, independent genetic incompatibilities that lead to a mosaic of genetic divergence and reproductive isolation across a species range. PMID- 29187974 TI - Likelihood of changes in forest species suitability, distribution, and diversity under future climate: The case of Southern Europe. AB - Forest conservation strategies and plans can be unsuccessful if the new habitat conditions determined by climate change are not considered. Our work aims at investigating the likelihood of future suitability, distribution and diversity for some common European forest species under the projected changes in climate, focusing on Southern Europe. We combine an Ensemble Platform for Species Distribution Models (SDMs) to five Global Circulation Models (GCMs) driven by two Representative Concentration Pathways (RCPs), to produce maps of future climate driven habitat suitability for ten categories of forest species and two time horizons. For each forest category and time horizon, ten maps of future distribution (5 GCMs by 2 RCPs) are thus combined in a single suitability map supplied with information about the "likelihood" adopting the IPCC terminology based on consensus among projections. Then, the statistical significance of spatially aggregated changes in forest composition at local and regional level is analyzed. Finally, we discuss the importance, among SDMs, that environmental predictors seem to have in influencing forest distribution. Future impacts of climate change appear to be diversified across forest categories. A strong change in forest regional distribution and local diversity is projected to take place, as some forest categories will find more suitable conditions in previously unsuitable locations, while for other categories the same new conditions will become less suited. A decrease in species diversity is projected in most of the area, with Alpine region showing the potentiality to become a refuge for species migration. PMID- 29187975 TI - Evolutionary structure of Plasmodium falciparum major variant surface antigen genes in South America: Implications for epidemic transmission and surveillance. AB - Strong founder effects resulting from human migration out of Africa have led to geographic variation in single nucleotide polymorphisms (SNPs) and microsatellites (MS) of the malaria parasite, Plasmodium falciparum. This is particularly striking in South America where two major founder populations of P. falciparum have been identified that are presumed to have arisen from the transatlantic slave trade. Given the importance of the major variant surface antigen of the blood stages of P. falciparum as both a virulence factor and target of immunity, we decided to investigate the population genetics of the genes encoding "Plasmodium falciparum Erythrocyte Membrane Protein 1" (Pf EMP1) among several countries in South America, in order to evaluate the transmission patterns of malaria in this continent. Deep sequencing of the DBLalpha domain of var genes from 128 P. falciparum isolates from five locations in South America was completed using a 454 high throughput sequencing protocol. Striking geographic variation in var DBLalpha sequences, similar to that seen for SNPs and MS markers, was observed. Colombia and French Guiana had distinct var DBLalpha sequences, whereas Peru and Venezuela showed an admixture. The importance of such geographic variation to herd immunity and malaria vaccination is discussed. PMID- 29187977 TI - Impacts of environmental factors on the climbing behaviors of herbaceous stem twiners. AB - The curvature of the helical trajectory formed by herbaceous stem-twiners has been hypothesized to be constant on uniformly sized cylindrical supports and remains constant on different supports varying in diameter. However, experimental studies on the constant curvature hypothesis have been very limited. Here, we tested the hypothesis in a series of experiments on five herbaceous stem-twiners (Ipomoea triloba, Ipomoea nil, Phaseolus vulgaris, Vigna unguiculata, and Mikania micrantha). We investigated how internode characteristics (curvature [beta], diameter [d], and length [L]) and success rate (SR) of twining shoots would be affected by support thickness (D), temperature (T), illumination, and support inclination. The results showed that: (1) the SR of tested species decreased, but d increased with increasing support thickness. The beta of the twining shoots on erect cylindrical poles was not constant, but it decreased with increasing d or support thickness. (2) The SR of tested species was not obviously reduced under low-temperature conditions, but their beta was significantly higher and d significantly lower when temperature was more than 5 degrees C lower. (3) The SR , d, and L of two tested Ipomoea species significantly declined, but beta increased under 50% shading stress. (4) The curvatures of upper semicycles of I. triloba shoots on 45 degrees inclined supports were not significantly different from curvatures of those shoots climb on erect supports, whereas the curvatures of lower semicycles were 40%-72% higher than curvatures of upper semicycles. Synthesis: Our study illustrates that stem curvatures of a certain herbaceous stem-twiners are not constant, but rather vary in response to external support, temperature, and illumination conditions. We speculate that herbaceous stem twiners positively adapt to wide-diameter supports by thickening their stems and by reducing their twining curvatures. This insight helps us better understand climbing processes and dynamics of stem-twiners in forest communities and ecosystems. PMID- 29187978 TI - Incubation behavior adjustments, driven by ambient temperature variation, improve synchrony between hatch dates and caterpillar peak in a wild bird population. AB - For organisms living in seasonal environments, synchronizing the peak energetic demands of reproduction with peak food availability is a key challenge. Understanding the extent to which animals can adjust behavior to optimize reproductive timing, and the cues they use to do this, is essential for predicting how they will respond to future climate change. In birds, the timing of peak energetic demand is largely determined by the timing of clutch initiation; however, considerable alterations can still occur once egg laying has begun. Here, we use a wild population of great tits (Parus major) to quantify individual variation in different aspects of incubation behavior (onset, duration, and daily intensity) and conduct a comprehensive assessment of the causes and consequences of this variation. Using a 54-year dataset, we demonstrate that timing of hatching relative to peak prey abundance (synchrony) is a better predictor of reproductive success than clutch initiation or clutch completion timing, suggesting adjustments to reproductive timing via incubation are adaptive in this species. Using detailed in-nest temperature recordings, we found that postlaying, birds improved their synchrony with the food peak primarily by varying the onset of incubation, with duration changes playing a lesser role. We then used a sliding time window approach to explore which spring temperature cues best predict variance in each aspect of incubation behavior. Variation in the onset of incubation correlated with mean temperatures just prior to laying; however, incubation duration could not be explained by any of our temperature variables. Daily incubation intensity varied in response to daily maximum temperatures throughout incubation, suggesting female great tits respond to temperature cues even in late stages of incubation. Our results suggest that multiple aspects of the breeding cycle influence the final timing of peak energetic demand. Such adjustments could compensate, in part, for poor initial timing, which has significant fitness impacts. PMID- 29187976 TI - Genome comparisons indicate recent transfer of wRi-like Wolbachia between sister species Drosophila suzukii and D. subpulchrella. AB - Wolbachia endosymbionts may be acquired by horizontal transfer, by introgression through hybridization between closely related species, or by cladogenic retention during speciation. All three modes of acquisition have been demonstrated, but their relative frequency is largely unknown. Drosophila suzukii and its sister species D. subpulchrella harbor Wolbachia, denoted wSuz and wSpc, very closely related to wRi, identified in California populations of D. simulans. However, these variants differ in their induced phenotypes: wRi causes significant cytoplasmic incompatibility (CI) in D. simulans, but CI has not been detected in D. suzukii or D. subpulchrella. Our draft genomes of wSuz and wSpc contain full length copies of 703 of the 734 single-copy genes found in wRi. Over these coding sequences, wSuz and wSpc differ by only 0.004% (i.e., 28 of 704,883 bp); they are sisters relative to wRi, from which each differs by 0.014%-0.015%. Using published data from D. melanogaster, Nasonia wasps and Nomada bees to calibrate relative rates of Wolbachia versus host nuclear divergence, we conclude that wSuz and wSpc are too similar-by at least a factor of 100-to be plausible candidates for cladogenic transmission. These three wRi-like Wolbachia, which differ in CI phenotype in their native hosts, have different numbers of orthologs of genes postulated to contribute to CI; and the CI loci differ at several nucleotides that may account for the CI difference. We discuss the general problem of distinguishing alternative modes of Wolbachia acquisition, focusing on the difficulties posed by limited knowledge of variation in absolute and relative rates of molecular evolution for host nuclear genomes, mitochondria, and Wolbachia. PMID- 29187980 TI - Biological soil crusts determine the germination and growth of two exotic plants. AB - In arid and semiarid ecosystems, the potential threats of exotic invasive species are enhanced due to increasing human activities. Biological soil crusts (BSCs), acting as arid ecosystem engineers, may play an important role in preventing the establishment of exotic invasive plants. Our goal was to examine whether BSCs could inhibit the establishment of probable exotic plant species originating from adjacent grasslands located along the southeast edge of the Tengger Desert. In our study, we investigated the effects of three BSC types (cyanobacteria, lichen, and moss crusts) under two disturbance conditions (intact and disturbed) on the establishment of two exotic plant species (Ceratoides latens and Setaria viridis) using indoor experiments. We found both negative and positive effects of BSCs on the establishment of the two exotic plant species. Compared with the disturbed BSCs, the germination percentages of C. latens and S. viridis were reduced by 54% to 87% and 89% to 93%, respectively, in intact BSCs. In contrast, BSCs significantly promoted the height growth and aboveground biomass of the two exotic plant species (p < .05) by enhancing the soil water and nutrient availability for the exotic plants. Our results confirm that BSCs strongly suppress the rapid expansion of exotic plant populations by inhibiting germination of seed with big size or appendages and have a weak inhibitory effect on exotic plant with small and smooth seeds. This may decrease the threat of propagation of exotic species. In the meantime, BSCs promote the growth of a few successful engraftment seedlings, which increased the beta diversity. Our work suggests that better understanding the two opposing effects of BSCs on the establishment of exotic plant species in different growth stages (germination and growth) is important for maintaining the health and stability of revegetated regions. PMID- 29187979 TI - Population genomics of the eastern cottonwood (Populus deltoides). AB - Despite its economic importance as a bioenergy crop and key role in riparian ecosystems, little is known about genetic diversity and adaptation of the eastern cottonwood (Populus deltoides). Here, we report the first population genomics study for this species, conducted on a sample of 425 unrelated individuals collected in 13 states of the southeastern United States. The trees were genotyped by targeted resequencing of 18,153 genes and 23,835 intergenic regions, followed by the identification of single nucleotide polymorphisms (SNPs). This natural P. deltoides population showed low levels of subpopulation differentiation (FST = 0.022-0.106), high genetic diversity (thetaW = 0.00100, pi = 0.00170), a large effective population size (Ne ~ 32,900), and low to moderate levels of linkage disequilibrium. Additionally, genomewide scans for selection (Tajima's D), subpopulation differentiation (XTX), and environmental association analyses with eleven climate variables carried out with two different methods (LFMM and BAYENV2) identified genes putatively involved in local adaptation. Interestingly, many of these genes were also identified as adaptation candidates in another poplar species, Populus trichocarpa, indicating possible convergent evolution. This study constitutes the first assessment of genetic diversity and local adaptation in P. deltoides throughout the southern part of its range, information we expect to be of use to guide management and breeding strategies for this species in future, especially in the face of climate change. PMID- 29187982 TI - Transgene flow in Mexican maize revisited: Socio-biological analysis across two contrasting farmer communities and seed management systems. AB - The flow of transgenes into landraces and wild relatives is an important biosafety concern. The case of transgene flow into local maize varieties in Mexico (the center of origin of maize) has been intensively debated over the past 15 years, including legal, political, and environmental disputes fanned by the existence of a significant scientific controversy over the methods used for the detection of transgenes. The use of diverse approaches and a lack of harmonized methods specific to the detection and monitoring of transgenes in landraces have generated both positive and negative results regarding contamination of Mexican maize with genetically modified material over the years. In this paper, we revisit the case of transgene contamination in Mexican maize and present a novel research approach based on socio-biological analysis of contrasting communities and seed management systems. Two communities were used to investigate how different social and biological factors can affect transgene flow and impact transgene spread in Mexico. Our results show the presence of transgenes in one community and thus support the position that transgenes are highly likely to be present in Mexican maize landraces. However, our work also demonstrates that the extent and frequency with which transgenes can be found will significantly depend on the societal characteristics and seed management systems of the local communities. Therefore, we argue that future analysis of transgene presence should include social research on the seed management practices in the sampling area so that more robust and comprehensive understandings and conclusions can be drawn. PMID- 29187981 TI - Clonality disguises the vulnerability of a threatened arid zone Acacia. AB - Long-lived, widespread plant species are expected to be genetically diverse, reflecting the interaction between large population sizes, overlapping generations, and gene flow. Such species are thought to be resilient to disturbance, but may carry an extinction debt due to reproductive failure. Genetic studies of Australian arid zone plant species suggest an unusually high frequency of asexuality, polyploidy, or both. A preliminary AFLP genetic study implied that the naturally fragmented arid zone tree, Acacia carneorum, is almost entirely dependent on asexual reproduction through suckering, and stands may have lacked genetic diversity and interconnection even prior to the onset of European pastoralism. Here we surveyed microsatellite genetic variation in 20 stands to test for variation in life histories and further assessed the conservation status of the species by comparing genetic diversity within protected stands in National Parks and disturbed range lands. Using herbarium records, we estimate that 219 stands are extant, all of which occur in the arid zone, west of the Darling River in southeastern Australia. With two exceptions, all surveyed stands comprised only one multilocus genet and at least eight were putatively polyploid. Although some stands comprise thousands of stems, our findings imply that the species as a whole may represent ~240 distinct genetic individuals, many of which are polyploid, and most are separated by >10 km of unsuitable habitat. With only 34% of stands (and therefore genets) occurring within conservation reserves, A. carneorum may be at much greater risk of extinction than inferred from on-ground census data. Land managers should prioritize on-ground preservation of the genotypes within existing reserves, protecting both vegetative suckers and seedlings from herbivory. Importantly, three stands are known to set viable seed and should be used to generate genetically diverse germ-plasm for ex situ conservation, population augmentation, or translocation. PMID- 29187983 TI - Tree species distribution in temperate forests is more influenced by soil than by climate. AB - Knowledge of the ecological requirements determining tree species distributions is a precondition for sustainable forest management. At present, the abiotic requirements and the relative importance of the different abiotic factors are still unclear for many temperate tree species. We therefore investigated the relative importance of climatic and edaphic factors for the abundance of 12 temperate tree species along environmental gradients. Our investigations are based on data from 1,075 forest stands across Switzerland including the cold induced tree line of all studied species and the drought-induced range boundaries of several species. Four climatic and four edaphic predictors represented the important growth factors temperature, water supply, nutrient availability, and soil aeration. The climatic predictors were derived from the meteorological network of MeteoSwiss, and the edaphic predictors were available from soil profiles. Species cover abundances were recorded in field surveys. The explanatory power of the predictors was assessed by variation partitioning analyses with generalized linear models. For six of the 12 species, edaphic predictors were more important than climatic predictors in shaping species distribution. Over all species, abundances depended mainly on nutrient availability, followed by temperature, water supply, and soil aeration. The often co-occurring species responded similar to these growth factors. Drought turned out to be a determinant of the lower range boundary for some species. We conclude that over all 12 studied tree species, soil properties were more important than climate variables in shaping tree species distribution. The inclusion of appropriate soil variables in species distribution models allowed to better explain species' ecological niches. Moreover, our study revealed that the ecological requirements of tree species assessed in local field studies and in experiments are valid at larger scales across Switzerland. PMID- 29187984 TI - Geographic variation in hybridization across a reinforcement contact zone of chorus frogs (Pseudacris). AB - Reinforcement contact zones, which are secondary contact zones where species are diverging in reproductive behaviors due to selection against hybridization, represent natural laboratories for studying speciation-in-action. Here, we examined replicate localities across the entire reinforcement contact zone between North American chorus frogs Pseudacris feriarum and P. nigrita to investigate geographic variation in hybridization frequencies and to assess whether reinforcement may have contributed to increased genetic divergence within species. Previous work indicated these species have undergone reproductive character displacement (RCD) in male acoustic signals and female preferences due to reinforcement. We also examined acoustic signal variation across the contact zone to assess whether signal characteristics reliably predict hybrid index and to elucidate whether the degree of RCD predicts hybridization rate. Using microsatellites, mitochondrial sequences, and acoustic signal information from >1,000 individuals across >50 localities and ten sympatric focal regions, we demonstrate: (1) hybridization occurs and (2) varies substantially across the geographic range of the contact zone, (3) hybridization is asymmetric and in the direction predicted from observed patterns of asymmetric RCD, (4) in one species, genetic distance is higher between conspecific localities where one or both have been reinforced than between nonreinforced localities, after controlling for geographic distance, (5) acoustic signal characters strongly predict hybrid index, and (6) the degree of RCD does not strongly predict admixture levels. By showing that hybridization occurs in all sympatric localities, this study provides the fifth and final line of evidence that reproductive character displacement is due to reinforcement in the chorus frog contact zone. Furthermore, this work suggests that the dual action of cascade reinforcement and partial geographic isolation is promoting genetic diversification within one of the reinforced species.

AB - Little is known about the natural history, biology, and population genetic structure of the Hardhead Silverside, Atherinomorus stipes, a small schooling fish found around islands throughout the Caribbean. Our field observations of A. stipes in the cays of Belize and the Florida Keys found that populations tend to be in close association with the shoreline in mangrove habitats. Due to this potential island-based population structuring, A. stipes represents an ideal system to examine questions about gene flow and isolation by distance at different geographic scales. For this study, the mitochondrial gene nd2 was amplified from 394 individuals collected from seven different Belizean Cays (N = 175) and eight different Floridian Keys (N = 219). Results show surprisingly high haplotype diversity both within and between island-groups, as well as a high prevalence of unique haplotypes within each island population. The results are consistent with models that require gene flow among populations as well as in situ evolution of rare haplotypes. There was no evidence for an isolation by distance model. The nd2 gene tree consists of two well-supported monophyletic groups: a Belizean-type clade and a Floridian-type clade, indicating potential species-level differentiation. PMID- 29187986 TI - Spatially varying density dependence drives a shifting mosaic of survival in a recovering apex predator (Canis lupus). AB - Understanding landscape patterns in mortality risk is crucial for promoting recovery of threatened and endangered species. Humans affect mortality risk in large carnivores such as wolves (Canis lupus), but spatiotemporally varying density dependence can significantly influence the landscape of survival. This potentially occurs when density varies spatially and risk is unevenly distributed. We quantified spatiotemporal sources of variation in survival rates of gray wolves (C. lupus) during a 21-year period of population recovery in the Upper Peninsula of Michigan, USA. We focused on mapping risk across time using Cox Proportional Hazards (CPH) models with time-dependent covariates, thus exploring a shifting mosaic of survival. Extended CPH models and time-dependent covariates revealed influences of seasonality, density dependence and experience, as well as individual-level factors and landscape predictors of risk. We used results to predict the shifting landscape of risk at the beginning, middle, and end of the wolf recovery time series. Survival rates varied spatially and declined over time. Long-term change was density-dependent, with landscape predictors such as agricultural land cover and edge densities contributing negatively to survival. Survival also varied seasonally and depended on individual experience, sex, and resident versus transient status. The shifting landscape of survival suggested that increasing density contributed to greater potential for human conflict and wolf mortality risk. Long-term spatial variation in key population vital rates is largely unquantified in many threatened, endangered, and recovering species. Variation in risk may indicate potential for source-sink population dynamics, especially where individuals preemptively occupy suitable territories, which forces new individuals into riskier habitat types as density increases. We encourage managers to explore relationships between adult survival and localized changes in population density. Density-dependent risk maps can identify increasing conflict areas or potential habitat sinks which may persist due to high recruitment in adjacent habitats. PMID- 29187987 TI - Using multiple data types and integrated population models to improve our knowledge of apex predator population dynamics. AB - Current management of large carnivores is informed using a variety of parameters, methods, and metrics; however, these data are typically considered independently. Sharing information among data types based on the underlying ecological, and recognizing observation biases, can improve estimation of individual and global parameters. We present a general integrated population model (IPM), specifically designed for brown bears (Ursus arctos), using three common data types for bear (U. spp.) populations: repeated counts, capture-mark-recapture, and litter size. We considered factors affecting ecological and observation processes for these data. We assessed the practicality of this approach on a simulated population and compared estimates from our model to values used for simulation and results from count data only. We then present a practical application of this general approach adapted to the constraints of a case study using historical data available for brown bears on Kodiak Island, Alaska, USA. The IPM provided more accurate and precise estimates than models accounting for repeated count data only, with credible intervals including the true population 94% and 5% of the time, respectively. For the Kodiak population, we estimated annual average litter size (within one year after birth) to vary between 0.45 [95% credible interval: 0.43; 0.55] and 1.59 [1.55; 1.82]. We detected a positive relationship between salmon availability and adult survival, with survival probabilities greater for females than males. Survival probabilities increased from cubs to yearlings to dependent young >=2 years old and decreased with litter size. Linking multiple information sources based on ecological and observation mechanisms can provide more accurate and precise estimates, to better inform management. IPMs can also reduce data collection efforts by sharing information among agencies and management units. Our approach responds to an increasing need in bear populations' management and can be readily adapted to other large carnivores. PMID- 29187988 TI - Landscape genomic approach to detect selection signatures in locally adapted Brazilian swine genetic groups. AB - Samples of 191 animals from 18 different Brazilian locally adapted swine genetic groups were genotyped using Illumina Porcine SNP60 BeadChip in order to identify selection signatures related to the monthly variation of Brazilian environmental variables. Using BayeScan software, 71 SNP markers were identified as FST outliers and 60 genotypes (58 markers) were found by Sambetaada software in 371 logistic models correlated with 112 environmental variables. Five markers were identified in both methods, with a Kappa value of 0.073 (95% CI: 0.011-0.134). The frequency of these markers indicated a clear north-south country division that reflects Brazilian environmental differences in temperature, solar radiation, and precipitation. Global spatial territory correlation for environmental variables corroborates this finding (average Moran's I = 0.89, range from 0.55 to 0.97). The distribution of alleles over the territory was not strongly correlated with the breed/genetic groups. These results are congruent with previous mtDNA studies and should be used to direct germplasm collection for the National gene bank. PMID- 29187989 TI - Resource selection by an ectothermic predator in a dynamic thermal landscape. AB - Predicting the effects of global climate change on species interactions has remained difficult because there is a spatiotemporal mismatch between regional climate models and microclimates experienced by organisms. We evaluated resource selection in a predominant ectothermic predator using a modeling approach that permitted us to assess the importance of habitat structure and local real-time air temperatures within the same modeling framework. We radio-tracked 53 western ratsnakes (Pantherophis obsoletus) from 2010 to 2013 in central Missouri, USA, at study sites where this species has previously been linked to prey population demographics. We used Bayesian discrete choice models within an information theoretic framework to evaluate the seasonal effects of fine-scale vegetation structure and thermal conditions on ratsnake resource selection. Ratsnake resource selection was influenced most by canopy cover, canopy cover heterogeneity, understory cover, and air temperature heterogeneity. Ratsnakes generally preferred habitats with greater canopy heterogeneity early in the active season, and greater temperature heterogeneity later in the season. This seasonal shift potentially reflects differences in resource requirements and thermoregulation behavior. Predicted patterns of space use indicate that ratsnakes preferentially selected open habitats in spring and early summer and forest-field edges throughout the active season. Our results show that downscaled temperature models can be used to enhance our understanding of animal resource selection at scales that can be addressed by managers. We suggest that conservation of snakes or their prey in a changing climate will require consideration of fine-scale interactions between local air temperatures and habitat structure. PMID- 29187990 TI - Increasing habitat complexity on seawalls: Investigating large- and small-scale effects on fish assemblages. AB - The construction of artificial structures in the marine environment is increasing globally. Eco-engineering aims to mitigate the negative ecological impacts of built infrastructure through designing structures to be multifunctional, benefiting both humans and nature. To date, the focus of eco-engineering has largely been on benefits for benthic invertebrates and algae. Here, the potential effect of eco-engineered habitats designed for benthic species on fish was investigated. Eco-engineered habitats ("flowerpots") were added to an intertidal seawall in Sydney Harbour, Australia. Responses of fish assemblages to the added habitats were quantified at two spatial scales; large (among seawalls) and small (within a seawall). Data were collected during high tide using cameras attached to the seawall to observe pelagic and benthic fish. At the larger spatial scale, herbivores, planktivores, and invertebrate predators were generally more abundant at the seawall with the added flowerpots, although results were temporally variable. At the smaller spatial scale, certain benthic species were more abundant around flowerpots than at the adjacent control areas of seawall, although there was no general pattern of differences in species density and trophic group abundance of pelagic fish between areas of the seawall with or without added habitats. Although we did not find consistent, statistically significant findings throughout our study, the field of research to improve fish habitat within human-use constraints is promising and important, although it is in its early stages (it is experimental and requires a lot of trial and error). To advance this field, it is important to document when effects were detected, and when they were not, so that others can refine the designs or scale of habitat enhancements or their study approaches (e.g., sampling protocols). PMID- 29187991 TI - Introduction history overrides social factors in explaining genetic structure of females in Mediterranean mouflon. AB - Fine-scale spatial genetic structure of populations results from social and spatial behaviors of individuals such as sex-biased dispersal and philopatry. However, the demographic history of a given population can override such socio spatial factors in shaping genetic variability when bottlenecks or founder events occurred in the population. Here, we investigated whether socio-spatial organization determines the fine-scale genetic structure for both sexes in a Mediterranean mouflon (Ovis gmelini musimon * Ovis sp.) population in southern France 60 years after its introduction. Based on multilocus genotypes at 16 loci of microsatellite DNA (n = 230 individuals), we identified three genetic groups for females and two for males, and concurrently defined the same number of socio spatial units using both GPS-collared individuals (n = 121) and visual resightings of marked individuals (n = 378). The socio-spatial and genetic structures did not match, indicating that the former was not the main driver of the latter for both sexes. Beyond this structural mismatch, we found significant, yet low, genetic differentiation among female socio-spatial groups, and no genetic differentiation in males, with this suggesting female philopatry and male biased gene flow, respectively. Despite spatial disconnection, females from the north of the study area were genetically closer to females from the south, as indicated by the spatial analysis of the genetic variability, and this pattern was in accordance with the common genetic origin of their founders. To conclude, more than 14 generations later, genetic signatures of first introduction are not only still detectable among females, but they also represent the main factor shaping their present-time genetic structure. PMID- 29187992 TI - Field evidence challenges the often-presumed relationship between early male maturation and female-biased sexual size dimorphism. AB - Female-biased sexual size dimorphism (SSD) is often considered an epiphenomenon of selection for the increased mating opportunities provided by early male maturation (i.e., protandry). Empirical evidence of the adaptive significance of protandry remains nonetheless fairly scarce. We use field data collected throughout the reproductive season of an SSD crab spider, Mecaphesa celer, to test two hypotheses: Protandry provides fitness benefits to males, leading to female-biased SSD, or protandry is an indirect consequence of selection for small male size/large female size. Using field-collected data, we modeled the probability of mating success for females and males according to their timing of maturation. We found that males matured earlier than females and the proportion of virgin females decreased abruptly early in the season, but unexpectedly increased afterward. Timing of female maturation was not related to clutch size, but large females tended to have more offspring than small females. Timing of female and male maturation was inversely related to size at adulthood, as early maturing individuals were larger than late-maturing ones, suggesting that both sexes exhibit some plasticity in their developmental trajectories. Such plasticity indicates that protandry could co-occur with any degree and direction of SSD. Our calculation of the probability of mating success along the season shows multiple male maturation time points with similar predicted mating success. This suggests that males follow multiple strategies with equal success, trading off access to virgin females with intensity of male-male competition. Our results challenge classic hypotheses linking protandry and female-biased SSD, and emphasize the importance of directly testing the often-assumed relationships between co-occurring animal traits. PMID- 29187994 TI - Detection of barriers to dispersal is masked by long lifespans and large population sizes. AB - Population genetic analyses of species inhabiting fragmented landscapes are essential tools for conservation. Occasionally, analyses of fragmented populations find no evidence of isolation, even though a barrier to dispersal is apparent. In some cases, not enough time may have passed to observe divergence due to genetic drift, a problem particularly relevant for long-lived species with overlapping generations. Failing to consider this quality during population structure analyses could result in incorrect conclusions about the impact of fragmentation on the species. We designed a model to explore how lifespan and population size influence perceived population structure of isolated populations over time. This iterative model tracked how simulated populations of variable lifespan and population size were affected by drift alone, using a freshwater mussel, Quadrula quadrula (mapleleaf), as a model system. In addition to exhibiting dramatic lifespan variability among species, mussels are also highly imperiled and exhibit fragmentation by dams throughout the range of many species. Results indicated that, unless population size was small (<50 individuals) or lifespan short (<22 years), observing genetic divergence among populations was unlikely. Even if wild populations are isolated, observing population structure in long-lived mussels from modern damming practices is unlikely because it takes longer for population structure to develop in these species than most North American dams have existed. Larger population sizes and longer lifespans increase the time needed for significant divergence to occur. This study helps illuminate the factors that influence genetic responses by populations to isolation and provides a useful model for conservation-oriented research. PMID- 29187993 TI - Phylogeography of Schizopygopsis stoliczkai (Cyprinidae) in Northwest Tibetan Plateau area. AB - Schizopygopsis stoliczkai (Cyprinidae, subfamily Schizothoracinae) is one of the major freshwater fishes endemic to the northwestern margin of the Tibetan Plateau. In the current study, we used mitochondrial DNA markers cytochrome b (Cyt b) and 16S rRNA (16S), as well as the nuclear marker, the second intron of the nuclear beta-actin gene (Act2), to uncover the phylogeography of S. stoliczkai. In total, we obtained 74 haplotypes from 403 mitochondrial concatenated sequences. The mtDNA markers depict the phylogenetic structures of S. stoliczkai, which consist of clade North and clade South. The split time of the two clades is dated back to 4.27 Mya (95% HPD = 1.96-8.20 Mya). The estimated split time is earlier than the beginning of the ice age of Pleistocene (2.60 Mya), suggesting that the northwestern area of the Tibetan Plateau probably contain at least two glacial refugia for S. stoliczkai. SAMOVA supports the formation of four groups: (i) the Karakash River group; (ii) The Lake Pangong group; (iii) the Shiquan River group; (iv) the Southern Basin group. Clade North included Karakash River, Lake Pangong, and Shiquan River groups, while seven populations of clade South share the haplotypes. Genetic diversity, star-like network, BSP analysis, as well as negative neutrality tests indicate recent expansions events of S. stoliczkai. Conclusively, our results illustrate the phylogeography of S. stoliczkai, implying the Shiquan River is presumably the main refuge for S. stoliczkai. PMID- 29187995 TI - Neutral lipid fatty acid composition as trait and constraint in Collembola evolution. AB - Functional traits determine the occurrence of species along environmental gradients and their coexistence with other species. Understanding how traits evolved among coexisting species helps to infer community assembly processes. We propose fatty acid composition in consumer tissue as a functional trait related to both food resources and physiological functions of species. We measured phylogenetic signal in fatty acid profiles of 13 field-sampled Collembola (springtail) species and then combined the data with published fatty acid profiles of another 24 species. Collembola fatty acid profiles generally showed phylogenetic signal, with related species resembling each other. Long-chain polyunsaturated fatty acids, related to physiological functions, demonstrated phylogenetic signal. In contrast, most food resource biomarker fatty acids and the ratios between bacterial, fungal, and plant biomarker fatty acids exhibited no phylogenetic signal. Presumably, fatty acids related to physiological functions have been constrained during Collembola evolutionary history: Species with close phylogenetic affinity experienced similar environments during divergence, while niche partitioning in food resources among closely related species favored species coexistence. Measuring phylogenetic signal in ecologically relevant traits of coexisting species provides an evolutionary perspective to contemporary assembly processes of ecological communities. Integrating phylogenetic comparative methods with community phylogenetic and trait-based approaches may compensate for the limitations of each method when used alone and improve understanding of processes driving and maintaining assembly patterns. PMID- 29187996 TI - Incorporating phylogenetic information for the definition of floristic districts in hyperdiverse Amazon forests: Implications for conservation. AB - Using complementary metrics to evaluate phylogenetic diversity can facilitate the delimitation of floristic units and conservation priority areas. In this study, we describe the spatial patterns of phylogenetic alpha and beta diversity, phylogenetic endemism, and evolutionary distinctiveness of the hyperdiverse Ecuador Amazon forests and define priority areas for conservation. We established a network of 62 one-hectare plots in terra firme forests of Ecuadorian Amazon. In these plots, we tagged, collected, and identified every single adult tree with dbh >=10 cm. These data were combined with a regional community phylogenetic tree to calculate different phylogenetic diversity (PD) metrics in order to create spatial models. We used Loess regression to estimate the spatial variation of taxonomic and phylogenetic beta diversity as well as phylogenetic endemism and evolutionary distinctiveness. We found evidence for the definition of three floristic districts in the Ecuadorian Amazon, supported by both taxonomic and phylogenetic diversity data. Areas with high levels of phylogenetic endemism and evolutionary distinctiveness in Ecuadorian Amazon forests are unprotected. Furthermore, these areas are severely threatened by proposed plans of oil and mining extraction at large scales and should be prioritized in conservation planning for this region. PMID- 29187997 TI - Internode morphometrics and allometry of Tonkin Cane Pseudosasa amabilis. AB - Pseudosasa amabilis (McClure) (Poales: Gramineae) is a typical bamboo species naturally distributed in large area of south China and famous for its culm strength. Although bamboos were found to share the same development rule, the detailed internode morphology of bamboo culm was actually not fully expressed. We explored internode morphology of P. amabilis using 11 different physical parameters in different dimensions (1-4). As Taylor's power law (TPL) is generally applicable to describe relationship between mean and variance of population density, here we used TPL to evaluate the differences between internodes, and further, the relationship between dimension and TPL. Results showed that length (L), hollow radius (HR), hollow area (HA), hollow cylinder volume (HCV), total cylinder volume (TCV), density (De), and weight (W) all presented positive skewed distribution in varying degrees. For the basic one dimensional parameters, the 9th internode was the longest, the 7th the heaviest, while thickness (T) decreased with internodes. Diameter (D) decreased in general but with an inconspicuous local mode at the 5-6th internodes, potentially due to the rapid height growth. The longest (9th) internode was the "turning point" for T-D and HR-D relationships. Scatter plot changing trends of W to the one dimensional parameters after the heaviest (7th) internode were reversed, indicating a deceleration of growth speed. TPL was not holding well in one dimensional parameters (R2: 0.5413-0.8125), but keep increasing as the parameter's dimension increasing (R2 > 0.92 for two-dimensional, R2 > 0.97 for three-dimensional, and R2 > 0.99 for four-dimensional parameters.), suggesting an emergence mechanism of TPL related to both the physical dimensions of morphological measures and the allometric growth of bamboo. From the physical fundamental level, all existences are the expression of energy distribution in different dimensions, implying a more general rule that energy distribution holds better TPL in higher dimension level. PMID- 29187998 TI - Quantifying resilience of multiple ecosystem services and biodiversity in a temperate forest landscape. AB - Resilience is increasingly being considered as a new paradigm of forest management among scientists, practitioners, and policymakers. However, metrics of resilience to environmental change are lacking. Faced with novel disturbances, forests may be able to sustain existing ecosystem services and biodiversity by exhibiting resilience, or alternatively these attributes may undergo either a linear or nonlinear decline. Here we provide a novel quantitative approach for assessing forest resilience that focuses on three components of resilience, namely resistance, recovery, and net change, using a spatially explicit model of forest dynamics. Under the pulse set scenarios, we explored the resilience of nine ecosystem services and four biodiversity measures following a one-off disturbance applied to an increasing percentage of forest area. Under the pulse + press set scenarios, the six disturbance intensities explored during the pulse set were followed by a continuous disturbance. We detected thresholds in net change under pulse + press scenarios for the majority of the ecosystem services and biodiversity measures, which started to decline sharply when disturbance affected >40% of the landscape. Thresholds in net change were not observed under the pulse scenarios, with the exception of timber volume and ground flora species richness. Thresholds were most pronounced for aboveground biomass, timber volume with respect to the ecosystem services, and ectomycorrhizal fungi and ground flora species richness with respect to the biodiversity measures. Synthesis and applications. The approach presented here illustrates how the multidimensionality of stability research in ecology can be addressed and how forest resilience can be estimated in practice. Managers should adopt specific management actions to support each of the three components of resilience separately, as these may respond differently to disturbance. In addition, management interventions aiming to deliver resilience should incorporate an assessment of both pulse and press disturbances to ensure detection of threshold responses to disturbance, so that appropriate management interventions can be identified. PMID- 29187999 TI - Effects of seasonality and environmental gradients on Spartina alterniflora allometry and primary production. AB - : Predictions of how salt marsh primary production and carbon storage will respond to environmental change can be improved through detailed datasets documenting responses to real-world environmental variation. To address a shortage of detailed studies of natural variation, we examined drivers of Spartina alterniflora stem allometry and productivity in seven marshes across three regions in southern Louisiana. Live-stem allometry varied spatially and seasonally, generally with short stems weighing more (and tall stems weighing less) in the summer and fall, differences that persist even after correcting for flowering. Strong predictive relationships exist between allometry parameters representing emergent stem mass and mass accumulation rates, suggesting that S. alterniflora populations navigate a trade-off between larger mass at emergence and faster rates of biomass accumulation. Aboveground production and belowground production were calculated using five and four approaches, respectively. End-of season aboveground biomass was a poor proxy for increment-based production measures. Aboveground production (Smalley) ranged from 390 to 3,350 g m-2 year-1 across all marshes and years. Belowground production (max-min) was on average three times higher than aboveground; total production ranged from 1,400 to 8,500 g m-2 year-1. Above- and belowground production were both positively correlated with dissolved nutrient concentrations and negatively correlated to salinity. SYNTHESIS: Interannual variation in water quality is sufficient to drive above- and belowground productivity. The positive relationship between nutrients and belowground production indicates that inputs of nutrients and freshwater may increase salt marsh carbon storage and ecosystem resilience to sea level rise. PMID- 29188000 TI - Optimizing methods to estimate zooplankton concentration based on generalized patterns of patchiness inside ballast tanks and ballast water discharges. AB - Zooplankton populations are spatially heterogeneous in nature and inside ship ballast tanks. Sampling methods should take heterogeneity into account, particularly when estimating quantitative variables such as abundance or concentration. It is particularly important to generate unbiased estimates of zooplankton concentration in ballast water when assessing compliance with new international ballast water discharge standards. We measured spatial heterogeneity of zooplankton within ballast water using three sampling methodologies. In-tank pump samples were collected at fixed depths within the vertical part of the ballast tank (side tank). Vertical net-haul samples were collected from the upper portion of the tank as a depth-integrated and historically relevant method. In-line, time-integrated samples were collected during ballast discharge by an isokinetic sample probe, likely representing the double bottom part of the ballast tank. The bias and precision associated with each sampling method were evaluated in reference to the estimated average abundance of the entire ballast tank, which was modeled from the data collected by all methods. In-tank pump samples provided robust evidence for vertical stratification of zooplankton concentration in the side tank. A consistent trend was also observed for in-line discharge samples, with zooplankton concentration decreasing through time as the ballast tank is being discharged. Sample representativeness, as compared to the tank average, varied depending on the depth or tank volume discharged. In-line discharge samples provided the least biased and most precise estimate of average tank abundance (having lowest mean squared error) when collected during the time frame of 20%-60% of the tank volume being discharged. Results were consistent across five trips despite differences in ballast water source, season, and age. PMID- 29188001 TI - Responses to a warming world: Integrating life history, immune investment, and pathogen resistance in a model insect species. AB - Environmental temperature has important effects on the physiology and life history of ectothermic animals, including investment in the immune system and the infectious capacity of pathogens. Numerous studies have examined individual components of these complex systems, but little is known about how they integrate when animals are exposed to different temperatures. Here, we use the Indian meal moth (Plodia interpunctella) to understand how immune investment and disease resistance react and potentially trade-off with other life-history traits. We recorded life-history (development time, survival, fecundity, and body size) and immunity (hemocyte counts, phenoloxidase activity) measures and tested resistance to bacterial (E. coli) and viral (Plodia interpunctella granulosis virus) infection at five temperatures (20-30 degrees C). While development time, lifespan, and size decreased with temperature as expected, moths exhibited different reproductive strategies in response to small changes in temperature. At cooler temperatures, oviposition rates were low but tended to increase toward the end of life, whereas warmer temperatures promoted initially high oviposition rates that rapidly declined after the first few days of adult life. Although warmer temperatures were associated with strong investment in early reproduction, there was no evidence of an associated trade-off with immune investment. Phenoloxidase activity increased most at cooler temperatures before plateauing, while hemocyte counts increased linearly with temperature. Resistance to bacterial challenge displayed a complex pattern, whereas survival after a viral challenge increased with rearing temperature. These results demonstrate that different immune system components and different pathogens can respond in distinct ways to changes in temperature. Overall, these data highlight the scope for significant changes in immunity, disease resistance, and host-parasite population dynamics to arise from small, biologically relevant changes to environmental temperature. In light of global warming, understanding these complex interactions is vital for predicting the potential impact of insect disease vectors and crop pests on public health and food security. PMID- 29188002 TI - Eggshells as hosts of bacterial communities: An experimental test of the antimicrobial egg coloration hypothesis. AB - Oviparous animals have evolved multiple defenses to prevent microbes from penetrating their eggs and causing embryo mortality. In birds, egg constituents such as lysozyme and antibodies defend against microbial infestation, but eggshell pigments might also impact survival of bacteria. If so, microbes could exert an important selective pressure on the evolution of eggshell coloration. In a previous lab experiment, eggshell protoporphyrin caused drastic mortality in cultures of Gram positive, but not Gram negative, bacteria when exposed to light. Here, we test this "photodynamic antimicrobial hypothesis" in a field experiment. In a paired experimental design, we placed sanitized brown, protoporphyrin-rich chicken eggs alongside white eggs that lack protoporphyrin. We deployed eggs for 48 hr without incubation, as can occur between laying and incubation, when microbial infection risk is highest. Eggs were placed on the open ground exposed to sunlight and in dark underground storm-petrel burrows. We predicted that the proportion of Gram-positive bacteria on brown eggs should be lower when exposed to sunlight than when kept in the dark, but we expected no such difference for white eggs. Although our data revealed variation in bacterial community composition, the proportion of Gram-positive bacteria on eggshells did not vary by egg color, and there was no interaction between egg color and location. Instead, Gram-positive bacteria were proportionally more common on eggs on the ground than eggs in burrows. Overall, our experiment did not support the photodynamic antimicrobial hypothesis. The diverse range of avian egg colors is generated by just two pigments, but over 10 hypotheses have been proposed for the evolution of eggshell color. If our results are generalizable, eggshell protoporphyrin might not play a substantial role in defending eggs against microbes, which narrows the field of candidate hypotheses for the evolution of avian eggshell coloration. PMID- 29188003 TI - Intraspecific and interspecific competition induces density-dependent habitat niche shifts in an endangered steppe bird. AB - Interspecific competition is a dominant force in animal communities that induces niche shifts in ecological and evolutionary time. If competition occurs, niche expansion can be expected when the competitor disappears because resources previously inaccessible due to competitive constraints can then be exploited (i.e., ecological release). Here, we aimed to determine the potential effects of interspecific competition between the little bustard (Tetrax tetrax) and the great bustard (Otis tarda) using a multidimensional niche approach with habitat distribution data. We explored whether the degree of niche overlap between the species was a density-dependent function of interspecific competition. We then looked for evidences of ecological release by comparing measures of niche breadth and position of the little bustard between allopatric and sympatric situations. Furthermore, we evaluated whether niche shifts could depend not only on the presence of great bustard but also on the density of little and great bustards. The habitat niches of these bustard species partially overlapped when co occurring, but we found no relationship between degree of overlap and great bustard density. In the presence of the competitor, little bustard's niche was displaced toward increased use of the species' primary habitat. Little bustard's niche breadth decreased proportionally with great bustard density in sympatric sites, in consistence with theory. Overall, our results suggest that density dependent variation in little bustard's niche is the outcome of interspecific competition with the great bustard. The use of computational tools like kernel density estimators to obtain multidimensional niches should bring novel insights on how species' ecological niches behave under the effects of interspecific competition in ecological communities. PMID- 29188004 TI - Leaf-IT: An Android application for measuring leaf area. AB - The use of plant functional traits has become increasingly popular in ecological studies because plant functional traits help to understand key ecological processes in plant species and communities. This also includes changes in diversity, inter- and intraspecific interactions, and relationships of species at different spatiotemporal scales. Leaf traits are among the most important traits as they describe key dimensions of a plant's life history strategy. Further, leaf area is a key parameter with relevance for other traits such as specific leaf area, which in turn correlates with leaf chemical composition, photosynthetic rate, leaf longevity, and carbon investment. Measuring leaf area usually involves the use of scanners and commercial software and can be difficult under field conditions. We present Leaf-IT, a new smartphone application for measuring leaf area and other trait-related areas. Leaf-IT is free, designed for scientific purposes, and runs on Android 4 or higher. We tested the precision and accuracy using objects with standardized area and compared the area measurements of real leaves with the well-established, commercial software WinFOLIA using the Altman Bland method. Area measurements of standardized objects show that Leaf-IT measures area with high accuracy and precision. Area measurements with Leaf-IT of real leaves are comparable to those of WinFOLIA. Leaf-IT is an easy-to-use application running on a wide range of smartphones. That increases the portability and use of Leaf-IT and makes it possible to measure leaf area under field conditions typical for remote locations. Its high accuracy and precision are similar to WinFOLIA. Currently, its main limitation is margin detection of damaged leaves or complex leaf morphologies. PMID- 29188005 TI - Connectivity, persistence, and loss of high abundance areas of a recovering marine fish population in the Northwest Atlantic Ocean. AB - In the early 1990s, the Northwest Atlantic Ocean underwent a fisheries-driven ecosystem shift. Today, the iconic cod (Gadus morhua) remains at low levels, while Atlantic halibut (Hippoglossus hippoglossus) has been increasing since the mid-2000s, concomitant with increasing interest from the fishing industry. Currently, our knowledge about halibut ecology is limited, and the lack of recovery in other collapsed groundfish populations has highlighted the danger of overfishing local concentrations. Here, we apply a Bayesian hierarchical spatiotemporal approach to model the spatial structure of juvenile Atlantic halibut over 36 years and three fisheries management regimes using three model parameters to characterize the resulting spatiotemporal abundance structure: persistence (similarity of spatial structure over time), connectivity (coherence of temporal pattern over space), and spatial variance (variation across the seascape). Two areas of high juvenile abundance persisted through three decades whereas two in the northeast are now diminished, despite the increased abundance and landings throughout the management units. The persistent areas overlap with full and seasonal area closures, which may act as refuges from fishing. Connectivity was estimated to be 250 km, an order of magnitude less than the distance assumed by the definition of the Canadian management units (~2,000 km). The underlying question of whether there are distinct populations within the southern stock unit cannot be answered with this model, but the smaller ~250 km scale of coherent temporal patterns suggests more complex population structure than previously thought, which should be taken into consideration by fishery management.

AB - Some South American poison frogs (Dendrobatidae) are chemically defended and use bright aposematic colors to warn potential predators of their unpalatability. Aposematic signals are often frequency-dependent where individuals deviating from a local model are at a higher risk of predation. However, extreme diversity in the aposematic signal has been documented in poison frogs, especially in Oophaga. Here, we explore the phylogeographic pattern among color-divergent populations of the Little Devil poison frog Oophaga sylvatica by analyzing population structure and genetic differentiation to evaluate which processes could account for color diversity within and among populations. With a combination of PCR amplicons (three mitochondrial and three nuclear markers) and genome-wide markers from a double-digested RAD (ddRAD) approach, we characterized the phylogenetic and genetic structure of 199 individuals from 13 populations (12 monomorphic and 1 polymorphic) across the O. sylvatica distribution. Individuals segregated into two main lineages by their northern or southern latitudinal distribution. A high level of genetic and phenotypic polymorphism within the northern lineage suggests ongoing gene flow. In contrast, low levels of genetic differentiation were detected among the southern lineage populations and support recent range expansions from populations in the northern lineage. We propose that a combination of climatic gradients and structured landscapes might be promoting gene flow and phylogenetic diversification. Alternatively, we cannot rule out that the observed phenotypic and genomic variations are the result of genetic drift on near or neutral alleles in a small number of genes. PMID- 29188007 TI - Enhancing the diversity of breeding invertebrates within field margins of intensively managed grassland: Effects of alternative management practices. AB - Severe declines in biodiversity have been well documented for many taxonomic groups due to intensification of agricultural practices. Establishment and appropriate management of arable field margins can improve the diversity and abundance of invertebrate groups; however, there is much less research on field margins within grassland systems. Three grassland field margin treatments (fencing off the existing vegetation "fenced"; fencing with rotavation and natural regeneration "rotavated" and; fencing with rotavation and seeding "seeded") were compared to a grazed control in the adjacent intensively managed pasture. Invertebrates were sampled using emergence traps to investigate species breeding and overwintering within the margins. Using a manipulation experiment, we tested whether the removal of grazing pressure and nutrient inputs would increase the abundance and richness of breeding invertebrates within grassland field margins. We also tested whether field margin establishment treatments, with their different vegetation communities, would change the abundance and richness of breeding invertebrates in the field margins. Exclusion of grazing and nutrient inputs led to increased abundance and richness in nearly all invertebrate groups that we sampled. However, there were more complex effects of field margin establishment treatment on the abundance and richness of invertebrate taxa. Each of the three establishment treatments supported a distinct invertebrate community. The removal of grazing from grassland field margins provided a greater range of overwintering/breeding habitat for invertebrates. We demonstrate the capacity of field margin establishment to increase the abundance and richness in nearly all invertebrate groups in study plots that were located on previously more depauperate areas of intensively managed grassland. These results from grassland field margins provide evidence to support practical actions that can inform Greening (Pillar 1) and agri-environment measures (Pillar 2) of the Common Agricultural Policy (CAP). Before implementing specific management regimes, the conservation aims of agri-environment measures should be clarified by defining the target species or taxonomic groups. PMID- 29188008 TI - Ecotypic differences in the phenology of the tundra species Eriophorum vaginatum reflect sites of origin. AB - Eriophorum vaginatum is a tussock-forming sedge that contributes significantly to the structure and primary productivity of moist acidic tussock tundra. Locally adapted populations (ecotypes) have been identified across the geographical distribution of E. vaginatum; however, little is known about how their growth and phenology differ over the course of a growing season. The growing season is short in the Arctic and therefore exerts a strong selection pressure on tundra species. This raises the hypothesis that the phenology of arctic species may be poorly adapted if the timing and length of the growing season change. Mature E. vaginatum tussocks from across a latitudinal gradient (65-70 degrees N) were transplanted into a common garden at a central location (Toolik Lake, 68 degrees 38'N, 149 degrees 36'W) where half were warmed using open-top chambers. Over two growing seasons (2015 and 2016), leaf length was measured weekly to track growth rates, timing of senescence, and biomass accumulation. Growth rates were similar across ecotypes and between years and were not affected by warming. However, southern populations accumulated significantly more biomass, largely because they started to senesce later. In 2016, peak biomass and senescence of most populations occurred later than in 2015, probably induced by colder weather at the beginning of the growing season in 2016, which caused a delayed start to growth. The finish was delayed as well. Differences in phenology between populations were largely retained between years, suggesting that the amount of time that these ecotypes grow has been selected by the length of the growing seasons at their respective home sites. As potential growing seasons lengthen, E. vaginatum may be unable to respond appropriately as a result of genetic control and may have reduced fitness in the rapidly warming Arctic tundra. PMID- 29188009 TI - Conservation implications for dingoes from the maternal and paternal genome: Multiple populations, dog introgression, and demography. AB - It is increasingly common for apex predators to face a multitude of complex conservation issues. In Australia, dingoes are the mainland apex predator and play an important role in ecological functioning. Currently, however, they are threatened by hybridization with modern domestic dogs in the wild. As a consequence, we explore how increasing our understanding of the evolutionary history of dingoes can inform management and conservation decisions. Previous research on whole mitochondrial genome and nuclear data from five geographical populations showed evidence of two distinct lineages of dingo. Here, we present data from a broader survey of dingoes around Australia using both mitochondrial and Y chromosome markers and investigate the timing of demographic expansions. Biogeographic data corroborate the presence of at least two geographically subdivided genetic populations, southeastern and northwestern. Demographic modeling suggests that dingoes have undergone population expansion in the last 5,000 years. It is not clear whether this stems from expansion into vacant niches after the extinction of thylacines on the mainland or indicates the arrival date of dingoes. Male dispersal is much more common than female, evidenced by more diffuse Y haplogroup distributions. There is also evidence of likely historical male biased introgression from domestic dogs into dingoes, predominately within southeastern Australia. These findings have critical practical implications for the management and conservation of dingoes in Australia; particularly a focus must be placed upon the threatened southeastern dingo population. PMID- 29188010 TI - Effects of macronutrient intake on the lifespan and fecundity of the marula fruit fly, Ceratitis cosyra (Tephritidae): Extreme lifespan in a host specialist. AB - In insects, lifespan and reproduction are strongly associated with nutrition. The ratio and amount of nutrients individuals consume affect their life expectancy and reproductive investment. The geometric framework (GF) enables us to explore how animals regulate their intake of multiple nutrients simultaneously and determine how these nutrients interact to affect life-history traits of interest. Studies using the GF on host-generalist tephritid flies have highlighted trade offs between longevity and reproductive effort in females, mediated by the protein-to-carbohydrate (P:C) ratio that individuals consume. Here, we tested how P and C intake affect lifespan (LS) in both sexes, and female lifetime (LEP), and daily (DEP) egg production, in Ceratitis cosyra, a host-specialist tephritid fly. We then determined the P:C ratio that C. cosyra defends when offered a choice of foods. Female LS was optimized at a 0:1 P:C ratio, whereas to maximize their fecundity, females needed to consume a higher P:C ratio (LEP = 1:6 P:C; DEP = 1:2.5 P:C). In males, LS was also optimized at a low P:C ratio of 1:10. However, when given the opportunity to regulate their intake, both sexes actively defended a 1:3 P:C ratio, which is closer to the target for DEP than either LS or LEP. Our results show that female C. cosyra experienced a moderate trade-off between LS and fecundity. Moreover, the diets that maximized expression of LEP and DEP were of lower P:C ratio than those required for optimal expression of these traits in host-generalist tephritids or other generalist insects. PMID- 29188011 TI - Evidence of separate subgroups of juvenile southern bluefin tuna. AB - Archival tagging studies of southern bluefin tuna (SBT , Thunnus maccoyii) have revealed that juveniles residing in the Great Australian Bight (GAB) over the austral summer undertake seasonal cyclic migrations to the southeast Indian Ocean and the Tasman Sea during winter. However, there remains disagreement about the extent of mixing between juvenile SBT regularly caught by longline fleets south of Africa and those observed in the GAB. Some researchers have argued that archival tag recoveries indicate most juveniles reside in the GAB over the austral summer. Others have suggested that recoveries of conventional and archival tags are better explained by a juvenile population consisting of separate groups on the eastern and western sides of the Indian Ocean with limited intermixing. We present analyses of catch and tag recovery data and re-examine archival tagging studies. The evidence provided strongly favors the hypothesis of separate juvenile subgroups, or contingents, with limited intermixing. We draw some tentative conclusions about the nature of the putative contingents and discuss some implications of these findings for the interpretation of existing datasets and future research priorities. We also provide the first evidence that the migration choices of juveniles that summer in the GAB are influenced by fidelity to winter feeding grounds and suggest this helps explain the collapse of the surface fishery off New South Wales in the 1980s. PMID- 29188012 TI - Creating, generating and comparing random network models with Network Randomizer. AB - Biological networks are becoming a fundamental tool for the investigation of high throughput data in several fields of biology and biotechnology. With the increasing amount of information, network-based models are gaining more and more interest and new techniques are required in order to mine the information and to validate the results. We have developed an app for the Cytoscape platform which allows the creation of randomized networks and the randomization of existing, real networks. Since there is a lack of tools for generating and randomizing networks, our app helps researchers to exploit different, well known random network models which could be used as a benchmark for validating real datasets. We also propose a novel methodology for creating random weighted networks starting from experimental data. Finally the app provides a statistical tool which compares real versus random attributes, in order to validate all the numerical findings. In summary, our app aims at creating a standardised methodology for the validation of the results in the context of the Cytoscape platform. PMID- 29188013 TI - Scaling-up primary health care-based prevention and management of alcohol use disorder at the municipal level in middle-income countries in Latin America: Background and pre-protocol for a three-country quasi-experimental study. AB - Background: While primary health care (PHC)-based prevention and management of alcohol use disorder (AUD) is clinically effective and cost-effective, it remains poorly implemented in routine practice. Systematic reviews and multi-country studies have demonstrated the ability of training and support programmes to increase PHC-based screening and brief advice activity to reduce heavy drinking. However, gains have been only modest and short term at best. WHO studies have concluded that a more effective uptake could be achieved by embedding PHC activity within broader community and municipal support. Protocol: A quasi experimental study will compare PHC-based prevention and management of AUD, operationalized by heavy drinking, in three intervention cities from Colombia, Mexico and Peru with three comparator cities from the same countries. In the implementation cities, primary health care units (PHCUs) will receive training embedded within ongoing supportive municipal action over an 18-month implementation period. In the comparator cities, practice as usual will continue at both municipal and PHCU levels. The primary outcome will be the proportion of consulting adult patients intervened with (screened and advice given to screen positives). The study is powered to detect a doubling of the outcome measure from an estimated 2.5/1,000 patients at baseline. Formal evaluation points will be at baseline, mid-point and end-point of the 18-month implementation period. We will present the ratio (plus 95% confidence interval) of the proportion of patients receiving intervention in the implementation cities with the proportions in the comparator cities. Full process evaluation will be undertaken, coupled with an analysis of potential contextual, financial and political-economy influencing factors. Discussion: This multi-country study will test the extent to which embedding PHC-based prevention and management of alcohol use disorder with supportive municipal action leads to improved scale-up of more patients with heavy drinking receiving appropriate advice and treatment. PMID- 29188014 TI - Assessment of injection safety in Ha Dong General Hospital, Hanoi, in 2012. AB - Background: Injection is one of the most frequently used medical methods to introduce drugs or other substances into the body for purposes of treatment or prevention. Unsafe injection can cause adverse outcomes, such as abscess and anaphylactic shock, and increases the risk of blood-borne transmission of viruses to patients and health care workers, as well as the community. Recognizing the importance of injection safety, in 2000 the Vietnamese Ministry of Health (MOH) collaborated with the Vietnam Nurses Association to launch the "Safe injection" program throughout the country, including Hanoi. Methods: This cross-sectional study, combining quantitative and qualitative analysis, was conducted from February to August 2012 in Ha Dong General Hospital using a structured questionnaire and observation checklist. The target population of the study was 109 nurses working in clinical departments and 436 injections were observed. Results: The percentage of nurses who are familiar with injection safety standards was found to be 82.6%. The proportion of practical injections that met the 23 standards of injection safety set by the MOH amounted to 22.2%. The factors related to safe injection practice of nurses who are younger age group (OR=3.1; p<0.05) and lower amount of working years (OR=2.8; p<0.05). Conclusions: A low proportion of nurses performed correct safety injection practice, which raises the need for further training about this issue, especially among older nurses. PMID- 29188016 TI - An analysis of characteristics of post-authorisation studies registered on the ENCePP EU PAS Register. AB - BACKGROUND: The objective of this study was to investigate the study design characteristics of Post-Authorisation Studies (PAS) requested by the European Medicines Agency which were recorded on the European Union (EU) PAS Register held by the European Network of Centres for Pharmacoepidemiology and Pharmacovigilance (ENCePP). METHODS: We undertook a cross-sectional descriptive analysis of all studies registered on the EU PAS Register as of 18 th October 2016. RESULTS: We identified a total of 314 studies on the EU PAS Register, including 81 (26%) finalised, 160 (51%) ongoing and 73 (23%) planned. Of those studies identified, 205 (65%) included risk assessment in their scope, 133 (42%) included drug utilisation and 94 (30%) included effectiveness evaluation. Just over half of the studies (175; 56%) used primary data capture, 135 (43%) used secondary data and 4 (1%) used a hybrid design combining both approaches. Risk assessment and effectiveness studies were more likely to use primary data capture (60% and 85% respectively as compared to 39% and 14% respectively for secondary). The converse was true for drug utilisation studies where 59% were secondary vs. 39% for primary. For type 2 diabetes mellitus, database studies were more commonly used (80% vs 3% chart review, 3% hybrid and 13% primary data capture study designs) whereas for studies in oncology, primary data capture were more likely to be used (85% vs 4% chart review, and 11% database study designs). CONCLUSIONS: Results of this analysis show that study objectives and therapeutic area influence PAS design in terms of type of data capture used. PMID- 29188017 TI - Identification of the ventral occipital visual field maps in the human brain. AB - The location and topography of the first three visual field maps in the human brain, V1-V3, are well agreed upon and routinely measured across most laboratories. The position of 4 th visual field map, 'hV4', is identified with less consistency in the neuroimaging literature. Using magnetic resonance imaging data, we describe landmarks to help identify the position and borders of 'hV4'. The data consist of anatomical images, visualized as cortical meshes to highlight the sulcal and gyral patterns, and functional data obtained from retinotopic mapping experiments, visualized as eccentricity and angle maps on the cortical surface. Several features of the functional and anatomical data can be found across nearly all subjects and are helpful for identifying the location and extent of the hV4 map. The medial border of hV4 is shared with the posterior, ventral portion of V3, and is marked by a retinotopic representation of the upper vertical meridian. The anterior border of hV4 is shared with the VO-1 map, and falls on a retinotopic representation of the peripheral visual field, usually coincident with the posterior transverse collateral sulcus. The ventro-lateral edge of the map typically falls on the inferior occipital gyrus, where functional MRI artifacts often obscure the retinotopic data. Finally, we demonstrate the continuity of retinotopic parameters between hV4 and its neighbors; hV4 and V3v contain iso-eccentricity lines in register, whereas hV4 and VO-1 contain iso polar angle lines in register. Together, the multiple constraints allow for a consistent identification of the hV4 map across most human subjects. PMID- 29188018 TI - Atopic dermatitis patients show increases in serum C-reactive protein levels, correlating with skin disease activity. AB - Background: Atopic dermatitis (AD), the most common chronic inflammatory skin disease, is evolving as a systemic disease, and associated systemic inflammation is possibly linked to increases in cardiovascular disease. Methods: We assessed levels of the inflammatory marker CRP in 59 patients with moderate-to-severe AD compared to matched healthy controls, and to determine correlation with skin disease severity. Clinical severity was measured using SCORing of Atopic Dermatitis (SCORAD) and body surface area (BSA). Control subjects (n=118), matched by age, gender, smoking status and ethnicity, were obtained from the National Health and Nutrition Survey (NHANES). Results: AD patients had significantly increased serum CRP levels compared to controls (0.7+/-1.0 vs. 0.4+/-0.7mg/dl; p=0.001). CRP levels were significantly correlated with both SCORAD (r=0.427, p=0.0008) and BSA (r=0.407, p=0.0015). IgE levels in AD were highly elevated (median 2903U/ml, IQR [234,10655]), but only weakly correlated with SCORAD (r=0.282, p=0.0427) and BSA (r=0.382, p=0.0052), but not with CRP levels. AD patients also showed increased LDH levels, but without significant correlations with disease severity (SCORAD, BSA) or CRP. Conclusions: Our study strongly supports CRP as a marker for disease severity in moderate-to-severe AD patients, further demonstrating its chronic systemic nature. PMID- 29188015 TI - A multi-disciplinary perspective on emergent and future innovations in peer review. AB - Peer review of research articles is a core part of our scholarly communication system. In spite of its importance, the status and purpose of peer review is often contested. What is its role in our modern digital research and communications infrastructure? Does it perform to the high standards with which it is generally regarded? Studies of peer review have shown that it is prone to bias and abuse in numerous dimensions, frequently unreliable, and can fail to detect even fraudulent research. With the advent of Web technologies, we are now witnessing a phase of innovation and experimentation in our approaches to peer review. These developments prompted us to examine emerging models of peer review from a range of disciplines and venues, and to ask how they might address some of the issues with our current systems of peer review. We examine the functionality of a range of social Web platforms, and compare these with the traits underlying a viable peer review system: quality control, quantified performance metrics as engagement incentives, and certification and reputation. Ideally, any new systems will demonstrate that they out-perform current models while avoiding as many of the biases of existing systems as possible. We conclude that there is considerable scope for new peer review initiatives to be developed, each with their own potential issues and advantages. We also propose a novel hybrid platform model that, at least partially, resolves many of the technical and social issues associated with peer review, and can potentially disrupt the entire scholarly communication system. Success for any such development relies on reaching a critical threshold of research community engagement with both the process and the platform, and therefore cannot be achieved without a significant change of incentives in research environments. PMID- 29188019 TI - lakemorpho: Calculating lake morphometry metrics in R. AB - Metrics describing the shape and size of lakes, known as lake morphometry metrics, are important for any limnological study. In cases where a lake has long been the subject of study these data are often already collected and are openly available. Many other lakes have these data collected, but access is challenging as it is often stored on individual computers (or worse, in filing cabinets) and is available only to the primary investigators. The vast majority of lakes fall into a third category in which the data are not available. This makes broad scale modelling of lake ecology a challenge as some of the key information about in lake processes are unavailable. While this valuable in situ information may be difficult to obtain, several national datasets exist that may be used to model and estimate lake morphometry. In particular, digital elevation models and hydrography have been shown to be predictive of several lake morphometry metrics. The R package lakemorpho has been developed to utilize these data and estimate the following morphometry metrics: surface area, shoreline length, major axis length, minor axis length, major and minor axis length ratio, shoreline development, maximum depth, mean depth, volume, maximum lake length, mean lake width, maximum lake width, and fetch. In this software tool article we describe the motivation behind developing lakemorpho, discuss the implementation in R, and describe the use of lakemorpho with an example of a typical use case. PMID- 29188020 TI - Case Report: Spontaneous cholecystocutaneous fistula, a rare cholethiasis complication. AB - One of the most unusual complications in cholethiasis is spontaneous cholecystocutaneous fistula, which has only been reported a few times in the literature. We report the case of a 76 year old man who presented with a right hypochondrium subcutaneous abscess, with pain evoked through palpation. No comorbidity in the patient's medical history were noted. Confirmation of cholecystocutaneous fistula was made using the proper diagnostic process, which is computed tomography with contrast media, followed by hepatobiliary MRI. This confirmed the presence of a fistulous pathway between the gallbladder and the skin. The patient underwent cholecystectomy surgery and open laparotomy with en block aponeurotic muscle, skin and fistula orifice excision. PMID- 29188022 TI - Induced spawning of siban fish Cyclocheilichthys apogon using Ovaprim. AB - Background: The objective of the present study was to examine the effect of Ovaprim dosage on the latency period, relative number of ovulated eggs, fertilization, hatching, and survival rates of the siban fish, Cyclocheilichthys apogon. Methods: Three dosages of Ovaprim were tested in this study, namely 0.3 ml kg-1 of broodfish body weight, 0.5 ml kg-1 body weight, and 0.7 ml kg-1 body weight, plus control (without Ovaprim). Results: The results showed that the best latency period, relative number of ovulated eggs, fertilization, hatching, and survival rates were obtained at a dosage of 0.7 ml kg -1 body weight. Conclusions: The best dosage of Ovaprim for siban fish from the dosages tested, was determined to be 0.7 ml kg-1 body weight. PMID- 29188023 TI - Draft genomes of two Australian strains of the plant pathogen, Phytophthora cinnamomi. AB - Background: The oomycete plant pathogen, Phytophthora cinnamomi, is responsible for the destruction of thousands of species of native Australian plants, as well as several crops, such as avocado and macadamia, and has one of the widest host plant ranges of the Phytophthora genus. The currently available genome of P. cinnamomi is based on an atypical strain and has large gaps in its assembly. To further studies of the pathogenicity of this species, especially in Australia, more robust assemblies of the genomes of more typical strains are required. Here we report the genome sequencing, draft assembly, and preliminary annotation of two geographically separated Australian strains of P. cinnamomi. Findings: Some 308 million raw reads were generated for the two strains. Independent genome assembly produced final genomes of 62.8 Mb (in 14,268 scaffolds) and 68.1 Mb (in 10,084 scaffolds), which are comparable in size and contiguity to other Phytophthora genomes. Gene prediction yielded > 22,000 predicted protein-encoding genes within each genome, while BUSCO assessment showed 82.5% and 81.8% of the eukaryote universal single-copy orthologs to be present in the assembled genomes, respectively. Conclusions: The assembled genomes of two geographically distant isolates of Phytophthora cinnamomi will provide a valuable resource for further comparative analysis and evolutionary studies of this destructive pathogen, and further annotation of the presented genomes may yield possible targets for novel pathogen control methods. PMID- 29188024 TI - Managing Persistent Hypoxemia: what is new? AB - Mechanical ventilation is the standard life-support technique for patients with severe acute respiratory failure. However, some patients develop persistent and refractory hypoxemia because their lungs are so severely damaged that they are unable to respond to the application of high inspired oxygen concentration and high levels of positive end-expiratory pressure. In this article, we review current knowledge on managing persistent hypoxemia in patients with injured lungs. PMID- 29188021 TI - Illustrative examples of probable transfer of resistance determinants from food animals to humans: Streptothricins, glycopeptides, and colistin. AB - Use, overuse, and misuse of antimicrobials contributes to selection and dissemination of bacterial resistance determinants that may be transferred to humans and constitute a global public health concern. Because of the continued emergence and expansion of antimicrobial resistance, combined with the lack of novel antimicrobial agents, efforts are underway to preserve the efficacy of current available life-saving antimicrobials in humans. As a result, uses of medically important antimicrobials in food animal production have generated debate and led to calls to reduce both antimicrobial use and the need for use. This manuscript, commissioned by the World Health Organization (WHO) to help inform the development of the WHO guidelines on the use of medically important antimicrobials in food animals, includes three illustrations of antimicrobial use in food animal production that has contributed to the selection-and subsequent transfer-of resistance determinants from food animals to humans. Herein, antimicrobial use and the epidemiology of bacterial resistance are described for streptothricins, glycopeptides, and colistin. Taken together, these historical and current narratives reinforce the need for actions that will preserve the efficacy of antimicrobials. PMID- 29188025 TI - Recent advances in understanding bile acid homeostasis. AB - Bile acids are derived from cholesterol to facilitate intestinal nutrient absorption and biliary secretion of cholesterol. Recent studies have identified bile acids as signaling molecules that activate nuclear farnesoid X receptor (FXR) and membrane G protein-coupled bile acid receptor-1 (Gpbar-1, also known as TGR5) to maintain metabolic homeostasis and protect liver and other tissues and cells from bile acid toxicity. Bile acid homeostasis is regulated by a complex mechanism of feedback and feedforward regulation that is not completely understood. This review will cover recent advances in bile acid signaling and emerging concepts about the classic and alternative bile acid synthesis pathway, bile acid composition and bile acid pool size, and intestinal bile acid signaling and gut microbiome in regulation of bile acid homeostasis. PMID- 29188026 TI - Is temperature an important variable in recovery after mild traumatic brain injury? AB - With nearly 42 million mild traumatic brain injuries (mTBIs) occurring worldwide every year, understanding the factors that may adversely influence recovery after mTBI is important for developing guidelines in mTBI management. Extensive clinical evidence exists documenting the detrimental effects of elevated temperature levels on recovery after moderate to severe TBI. However, whether elevated temperature alters recovery after mTBI or concussion is an active area of investigation. Individuals engaged in exercise and competitive sports regularly experience body and brain temperature increases to hyperthermic levels and these temperature increases are prolonged in hot and humid ambient environments. Thus, there is a strong potential for hyperthermia to alter recovery after mTBI in a subset of individuals at risk for mTBI. Preclinical mTBI studies have found that elevating brain temperature to 39 degrees C before mTBI significantly increases neuronal death within the cortex and hippocampus and also worsens cognitive deficits. This review summarizes the pathology and behavioral problems of mTBI that are exacerbated by hyperthermia and discusses whether hyperthermia is a variable that should be considered after concussion and mTBI. Finally, underlying pathophysiological mechanisms responsible for hyperthermia induced altered responses to mTBI and potential gender considerations are discussed. PMID- 29188027 TI - Recent advances in the understanding and management of bipolar disorder in adults. AB - This article focuses on some aspects of recent progress in the neurobiology and treatment of bipolar disorder (BD) in adults. A molecular-genetic approach to the etiopathogenesis of the illness resulted in the findings of a genetic overlap between BD and other major psychiatric disorders. Furthermore, a poly-gene environmental interaction in the development of the illness has been demonstrated. For the management of BD, new drugs with putative mood-stabilizing properties have been introduced in the past two decades. However, none of these can surpass lithium, the prototype mood-stabilizer, still considered the most specific drug for BD. Recent research on lithium, besides providing new data on the neurobiology of BD, has confirmed anti-suicidal, immunomodulatory, and neuroprotective properties of this drug. PMID- 29188028 TI - Evolution of blood pressure management in acute intracerebral hemorrhage. AB - Intracerebral hemorrhage (ICH) remains a prevalent and severe cause of death and disability worldwide. Control of the hypertensive response in acute ICH has been a mainstay of ICH management, yet the optimal approaches and the yield of recommended strategies have been difficult to establish despite a large body of literature. Over the years, theoretical and observed risks and benefits of intensive blood pressure reduction in ICH have been studied in the form of animal models, radiographic studies, and two recent large, randomized patient trials. In this article, we review the historical and developing data and discuss remaining questions surrounding blood pressure management in acute ICH. PMID- 29188030 TI - Monosodium glutamate as a tool to reduce sodium in foodstuffs: Technological and safety aspects. AB - Sodium chloride (NaCl) is the most commonly used ingredient to provide salty taste to foods. However, excess sodium in the bloodstream has been associated with the development of several chronic noncommunicable diseases. In order to limit sodium intake to levels considered safe, the World Health Organization (WHO) recommends for adults a daily intake of not more than 5 g of NaCl (less than 2 g of sodium). One of the strategic actions recommended by the Pan American Health Organization (PAHO) to reduce sodium intake is reformulation of processed foods. This recommendation indicates there is an urgent need to find salt substitutes, and umami compounds have been pointed as an alternative strategy. Like salty, umami is also a basic taste and the major compound associated to umami is monosodium L-glutamate (MSG). The available scientific data on the toxicity of MSG has been evaluated by scientific committees and regulatory agencies. The Joint FAO/WHO Expert Committee on Food Additives and the Scientific Committee on Food of the European Commission established an acceptable daily intake (ADI) not specified, which indicated that the substance offers no health risk when used as a food additive. The United States Food and Drug Administration and the Federation of American Societies for Experimental Biology classified MSG as a Generally Recognized as Safe (GRAS) substance. In this paper, an overview about salty and umami taste physiology, the potential applications of MSG use to reduce sodium content in specific industrialized foods and safety aspects of MSG as food additive are presented. PMID- 29188029 TI - Distributional benefits of tobacco tax and smoke-free workplaces in China: A modeling study. AB - Background: Tobacco taxation and smoke-free workplaces reduce smoking, tobacco related premature deaths and associated out-of-pocket health care expenditures. We examine the distributional consequences of a price increase in tobacco products through an excise tax hike, and of an implementation of smoke-free workplaces, in China. Methods: We use extended cost-effectiveness analysis (ECEA) to evaluate, across income quintiles of the male population (the large majority of Chinese smokers), the premature deaths averted, the change in tax revenues generated, and the financial risk protection procured (eg, poverty cases averted, defined as the number of individuals no longer facing tobacco-related out-of pocket expenditures for disease treatment, that would otherwise impoverish them), that would follow a 75% increase in cigarette prices through substantial increments in excise tax fully passed onto consumers, and a nationwide total implementation of workplace smoking bans. Results: A 75% increase in cigarette prices would avert about 24 million premature deaths among the current Chinese male population, with a third among the bottom income quintile, increase additional tax revenues by US$ 46 billion annually, and prevent around 9 million poverty cases, 19% of which among the bottom income quintile. Implementation of smoking bans in workplaces would avert about 12 million premature deaths, with a fifth among the bottom income quintile, decrease tax revenues by US$ 7 billion annually, and prevent around 4 million poverty cases, 12% of which among the bottom income quintile. Conclusions: Increased excise taxes on tobacco products and workplace smoking bans can procure large health and economic benefits to the Chinese population, especially among the poor.

AB - Combining different preservative treatments for improving quality and safety of fishery products increasingly receives global research attention. Consistent with this pursuit, the current research was undertaken to determine the effects of different ozonized slurry-ice treatments and superchilling (-1 degrees C) storage on microbial spoilage of European anchovy (Eugraulis encrasicolus) and sardine (Sardina pilchardus), which are two commercially important pelagic fish species. After the catch (within <5 hr) and at defined scheduled storage times, ozone has been discharged once on sardine (herein referred to as "One-T") and repeatedly/sequentially on European anchovy (herein referred to as "Seq-T"). Microbiological analyses enumerated total viable count (TVC), Bacillus spp., Enterobacteriaceae, Lactobacillus spp., Moraxella spp., Shewanella spp., Listeria monocytogenes and Pseudomonas spp. Independent of potential antimicrobial effects of ozone during superchilling storage, no Listeria spp., Shewanella spp., Moraxella spp., and Bacillus spp. were found in all processed samples. While Enterobacteriaceae and Lactobacillus spp. were detected at below 1 log cfu/g, both TVC and Pseudomonas spp. proliferated at different rates throughout superchilling storage. The repeated ozone-treated ("Seq-T") showed lower TVC and Pseudomonas spp. values compared with one-time treated ("One-T") slurry-iced and control samples. Thus, combined slurry-ice and superchilling storage at Seq-T produced improved antimicrobial activity over One-T application. Largely, ozonized slurry-ice outcomes/results appear promising thanks to superchilling storage.

AB - Due to early deterioration of banana in drying process, almond, quince seed, and tragacanth gums as edible coatings were determined. For this purpose, banana slices were coated in 0.7% solution of each gum and one group remained uncoated as the control. The samples were examined at specific times considering the weight loss, color analyzing (a*, b*, and L*) through the method computer vision, color difference index, browning index, and rehydration after the samples being dried. The results showed that the weight loss of the coated samples was significantly (p < .05) higher than the uncoated samples which can be due to the alteration or destruction of the cell membrane. The almond gum-coated samples had significantly a lower ultimate browning index and quince seed gum-coated samples showed the highest rehydration. So, the gums coating is an effective way to preserve the quality characteristics of the banana slices. PMID- 29188033 TI - Simple methods to reduce major allergens Ara h 1 and Ana o 1/2 in peanut and cashew extracts. AB - Whole peanut or cashew extracts are usually used in immunotherapy. Reducing major allergen(s) in the extracts may lessen their side effects. Three methods were evaluated to reduce major allergens in peanut extracts: (1) p-aminobenzamidine; (2) magnetic agarose beads; and (3) extraction of a commercial peanut flour at pH 7, respectively. The first two methods were also used to reduce major allergens in cashew extracts. After treatments, samples were evaluated by SDS-PAGE. pABA treated samples were also analyzed for IgE binding in western blot. We found that the methods resulted in peanut extracts lacking detectable Ara h 1 but containing Ara h 2/6 and cashew extract lacking Ana o 1/2, but containing Ana o 3. Consequently, reduced IgE binding was observed. We conclude that the methods are useful for producing peanut or cashew extract with little Ara h 1 or Ana o 1/2. PMID- 29188034 TI - Viscoelastic properties of sweet potato complementary porridges as influenced by endogenous amylases. AB - Sweet potato (Ipomoea batatas L.) roots contain amylolytic enzymes, which hydrolyze starch thus having the potential to affect the viscosity of sweet potato porridges provided the appropriate working conditions for the enzymes are attained. In this study, the effect of sweet potato variety, postharvest handling conditions, freshly harvested and room/ambient stored roots (3 weeks), and slurry solids content on the viscoelastic properties of complementary porridges prepared using amylase enzyme activation technique were investigated. Five temperatures (55 degrees C, 65 degrees C, 70 degrees C, 75 degrees C, and 80 degrees C) were used to activate sweet potato amylases and the optimum temperature was found to be 75 degrees C. Stored sweet potato roots had higher soluble solids (0Brix) content in the pastes compared to fresh roots. In all samples, activation of amylases at 75 degrees C caused changes in the viscoelastic parameters: phase angle (tan delta) and complex viscosity (eta*). Postharvest handling conditions and slurry solids content significantly affected the viscoelastic properties of the porridges with flours from stored roots yielding viscous (liquid-like) porridges and fresh roots producing elastic (solid-like) porridges. Increase in slurry solids content caused reduction in the phase angle values and increase in the viscosity of the sweet potato porridges. The viscosity of the porridges decreased with storage of sweet potato roots. These results provide a possibility for exploiting sweet potato endogenous amylases in the preparation of complementary porridges with both drinkable viscosities and appropriate energy and nutrient densities for children with varying energy needs.

AB - Oxidation processes in milk and yogurt during the shelf life can result in an alteration of protein and lipid constituents. Therefore, the antioxidant properties of yogurt in standard conditions of preservation were evaluated. Total phenols, free radical scavenger activity, degree of lipid peroxidation, and protein oxidation were determined in plain and skim yogurts with or without fruit puree. After production, plain, skim, plain berries, and skim berries yogurts were compared during the shelf life up to 9 weeks. All types of yogurts revealed a basal antioxidant activity that was higher when a fruit puree was present but gradually decreased during the shelf life. However, after 5-8 weeks, antioxidant activity increased again. Both in plain and berries yogurts lipid peroxidation increased until the seventh week of shelf life and after decreased, whereas protein oxidation of all yogurts was similar either in the absence or presence of berries and increased during shelf life. During the shelf life, a different behavior between lipid and protein oxidation takes place and the presence of berries determines a protection only against lipid peroxidation. PMID- 29188036 TI - Influence of development, postharvest handling, and storage conditions on the carbohydrate components of sweetpotato (Ipomea batatas Lam.) roots. AB - Changes in total starch and reducing sugar content in five sweetpotato varieties were investigated weekly during root development and following subjection of the roots to different postharvest handling and storage conditions. Freshly harvested (noncured) roots and cured roots (spread under the sun for 4 days at 29-31 degrees C and 63-65% relative humidity [RH]) were separately stored at ambient conditions (23 degrees C-26 degrees C and 70-80% RH) and in a semiunderground pit (19-21 degrees C and 90-95% RH). Changes in pasting properties of flour from sweetpotato roots during storage were analyzed at 14-day intervals. Significant varietal differences (p < .05) in total starch, sucrose, glucose, maltose, and fructose concentrations were registered. The total starch and sucrose content of the roots did not change significantly (p < .05) during root development (72.4 and 7.4%, respectively), whereas the average concentrations of glucose, maltose, and fructose decreased markedly (0.46-0.18%, 0.55-0.28%, and 0.43-0.21%), respectively. Storage led to decrease in total starch content (73-47.7%) and increase in sucrose and glucose concentrations (8.1-11.2% and 0.22-1.57%, respectively). Storage also resulted in reduction in sweetpotato flour pasting viscosities. Curing resulted in increased sucrose and glucose concentrations (9.1 11.2% and 0.45-0.85%, respectively) and marked reduction (p < .05) in total starch content (72.9-47.6%). This resulted in low pasting viscosities compared to flour from storage of uncured roots. These findings show that significant changes occur in the carbohydrate components of sweetpotato roots during storage compared to development and present an opportunity for diverse utilization of flours from sweetpotato roots in the food industry. PMID- 29188037 TI - Influence of physicochemical parameters on storage stability: Microbiological quality of fresh unpasteurized fruit juices. AB - Fresh juices rich in health and nutritional benefits are valued for their fresh flavor, taste, and aroma. These juices' quality however is affected by factors like temperature, light, and microbiological contamination significantly changing physicochemical parameters and storage stability. Physicochemical and microbiological analyses of passion fruit, pineapple, and mango juices in dark and light bottles at 24 degrees C and 4 degrees C were conducted in Kampala, Uganda for 12 days. Physicochemical parameters significantly reduced (p < .05) storage stability of fresh juices, while no significant changes (p > .05) were observed for the microbiological analyses. pH values ranged from 3.0 to 4.2 (dark) bottles and 2.9 to 4.0 (light) bottles for juices at 24 degrees C and 4 degrees C. degrees Brix values were from 1.0 to 5.5 for dark and clear bottles at 24 degrees C and 4 degrees C. TTA (%) values ranged from 1.1 to 7.2 (dark) bottles and 1.1 to 7.4 for (light) bottles at 24 degrees C and 4 degrees C. Ascorbic acid content ranged from 3.5 to 61.0 mg/ 100 ml and 5.5 to 56.7 mg/100 ml for juices in dark and clear bottles, respectively. total plate counts ranged from 1.3 * 10___ to 3.3 * 107 CFU/ml (dark bottles at 24 degrees C) to 3.5 * 103 to 3.3 * 108 CFU/ml (dark bottles at 4 degrees C). For juices in light bottles, total plate counts ranged from 1.8 * 10___ to 8.0 * 107 CFU/ml (24 degrees C) and 2.7 * 10___ to 1.5 * 108 CFU/ml (4 degrees C). High microbial loads suggest the use of poor processing techniques and lack of good hygiene which lower quality and reduce storage stability of juices. Storage temperature greatly reduces physicochemical parameters both at ambient and refrigeration temperatures. This implies that temperature control for unpasteurized juices is critical in order to inhibit microorganism metabolic activities which accelerate biodeterioration leading to spoilage and short shelf life. Fresh unpasteurized juices stored at 24 degrees C and 4 degrees C may safely be consumed within 1 and 2 days, respectively. PMID- 29188038 TI - Effects of cooking and fermentation on the chemical composition, functional, and antinutritional properties of kariya (Hildergardia barteri) seeds. AB - The effects of natural fermentation and cooking on kariya seeds functional properties, chemical composition, and antinutritional properties were evaluated. Result showed a reduction in antinutritional properties and improvement in protein content which were observed to increase with cooking (at 100 degrees C) and fermentation period (24-96 hr). Functional analyses showed an increase in foaming and emulsion properties, while water absorption capacity and swelling power were observed to likewise increase with an increasing temperature between 60 degrees C and 90 degrees C. There was also an improvement in foaming properties with increase in salt (NaCl) concentration, while emulsifying property decreases with an increase in salt (NaCl) concentration. Based on the result of the findings of this study, it can be stated that the cooking and fermentation processes employed in this study can enhance the domestic and industrial utilization of these seeds. PMID- 29188039 TI - Nutritional variation in baobab (Adansonia digitata L.) fruit pulp and seeds based on Africa geographical regions. AB - Baobab (Adansonia digitata L.) is an indigenous fruit tree associated with the Savannah drylands of sub-Saharan Africa. Local communities mainly utilize the leaves, pulp, and seeds of baobab as a source of food and for income generation. The present study was conducted to determine the nutritive attributes of baobab fruit pulp and seeds across provenances in east, west, and southern Africa and to determine whether the nutrient content varied with the provenance of origin. Pulp and seed proximate composition and mineral element concentration were determined using the AOAC 1984 methods and inductively coupled plasma atomic emission spectroscopy (ICP-AES), respectively. The results showed that there exist significant variation (p < .05) in pulp moisture, protein, fiber, ash, and elemental content among provenances. The highest mean pulp crude fiber (8.68 g 100 g-1 dw) was recorded in Kenya. At country level, Malawi had the highest mean pulp potassium (22.2 mg g-1), calcium (4,300 mg kg-1), magnesium (2,300 mg kg-1), sodium (1,000 mg kg-1), and phosphorus (1,100 mg kg-1) levels. Kenya had the highest mean pulp iron (57.4 MUg g-1) and manganese (27.2 MUg g-1) content, while Mali had the lowest iron (13.1 MUg g-1) and manganese (8.6 MUg g-1). At country level, the mean seed calcium content was highest (3,200 mg kg-1) in Malawi and lowest (2,000 mg kg-1) in Kenya. The highest mean iron content of 63.7 MUg g-1 was recorded in seeds from Kenya, while the lowest (25.8 MUg g-1) was in Mali. Baobab seed mineral and proximate content varied significantly (p < .001) among the selected countries. Overall, baobab fruit pulp and seeds contain significant amounts of nutritionally essential minerals and proximate components but the amounts varied significantly among the selected countries. This variation offers opportunities for selecting provenances to concentrate on during germplasm collection for conservation and domestication of baobab. PMID- 29188040 TI - Evaluation of peanut skin and grape seed extracts to inhibit growth of foodborne pathogens. AB - Peanut skin extract (PSE) and grape seed extract (GSE) are derived from waste products in the wine and peanut industries, respectively. Both have high concentrations of polyphenols, known to possess antioxidant and antimicrobial properties. PSE primarily contains "A-type" procyanidins, while GSE primarily contains "B-type" procyanidins. These differ structurally, but are both isomers of epicatechin dimers. The objective of this study was to evaluate the antimicrobial effects of PSE containing A-type procyanidins and GSE containing B type procyanidins against select foodborne pathogens (Listeria monocytogenes, Escherichia coli O157:H7, and Salmonella Typhimurium). The minimum inhibitory concentration (MIC) of the two extracts on L. monocytogenes, E. coli O157:H7, and S. Typhimurium was determined using the pour plate method. GSE had a significantly lower MIC (p <= .05) than PSE for L. monocytogenes (GSE = 60.6 ppm, PSE > 68.2 ppm) and S. Typhimurium (GSE = 45.7 ppm, PSE = 60.6 ppm), but no difference in inhibition of E. coli O157:H7. Since GSE contributed to greater inhibition, GSE extract was fractionated into monomer-rich (consisting primarily of catechins, epicatechins, and epicatechin gallates) and oligomer-rich (consisting of dimers, trimers, tetramers, up to decamers) components. Growth curves of all three pathogens in the presence of full extract, monomer and oligomer fractions were compared separately. None of the extracts inhibited S. Typhimurium growth. Generally, the extract containing greater oligomer components inhibited growth of L. monocytogenes and E. coli O157:H7 when compared to the control. Results indicate that an extract with type B procyanidins higher in oligomers may have greater antimicrobial properties. PMID- 29188041 TI - Effect of processing methods on the nutritional content of three traditional vegetables leaves: Amaranth, black nightshade and jute mallow. AB - The study assessed changes in nutritional content of some commonly consumed traditional vegetables subjected to postharvest processes. Amaranth (Amaranthus cruentus L.), black nightshade (Solanum scabrum Mill.) and jute mallow (Corchorus olitorius L.) leaves used as vegetables were subjected to blanching, boiling and drying. The proximate composition and beta-carotene content of fresh and processed leaves were determined. Amaranth, black nightshade and jute mallow leaves had 25.21%, 39.74% and 29.18% of protein, respectively. The beta-carotene levels were 16.40, 25.25 and 27.74 mg/100 g for black nightshade amaranth and jute mallow leaves, respectively. The ash content was 10.57% for black nightshade, 12.40% for jute mallow and 16.33% for amaranth. Processing methods caused decreases of beta-carotene and crude lipid content. Boiling for 30 min or more resulted in large loss of beta-carotene. Drying under shade resulted in less loss of beta-carotene than drying in cabinet at 50 and 60 degrees C. PMID- 29188042 TI - Partial characterization of starches from major banana (matooke) cultivars grown in Uganda. AB - The SEM of starch from five EAHB cultivars showed a mixture of irregular granule shapes with smooth surfaces. The starches' average diameter size ranged between 16.31 and 21.98 MUm. The moisture, protein, and ash content of the starches were: 11.12%-11.84%, 0.1% and 0.23%-0.47% respectively. The amylose content of these starches was between 11% and 13%. The starches peak viscosity ranged between 488.42 and 558.66 RVU. The EAHB starches exhibited relatively low pasting temperatures (<75 degrees C), a high peak viscosity (488.42-558.71 RVU), high level of viscosity breakdown (235.00-311.92 RVU) and low set-back values (61.21 104.33 RVU). In general, the EAHB starches' WHCs and SPs increased substantially at 80 degrees C with maximum SP (12.43-14.27 g water/g starch) and solubility (12.52%-14.19%) values obtained at 90 degrees C. The starch clarity ranged from 1.7% to 2.3% and followed the same pattern. The starches exhibited poor freeze thaw stability as they had high syneresis (68% to 72%) after 10 freeze-thaw cycles. PMID- 29188043 TI - Household food insecurity, coping strategies, and nutritional status of pregnant women in rural areas of Northern Ghana. AB - There is limited information on the magnitude and determinants of household food insecurity (HFI) and how it relates to the nutritional status of pregnant women in Northern Ghana. The magnitude, determinants of HFI, and how it relates to the nutritional status of pregnant women were evaluated in the Africa RISING West Africa project intervention communities in Northern Ghana. The prevalence of moderate and severe household hunger was 25.9% (95% CI: 19.0, 34.3) and 6.8% (95% CI: 4.2, 10.9) respectively. The independent predictors of maternal thinness were region of residence, gestational age and maternal age. Compared to women in the first trimester, women in the third trimester were 2.2 times more likely of being underweight adjusted odds ratio (AOR = 2.19, CI: 1.02, 4.70). Women who were under 20 years of age were 11.9 times more likely of being thin compared to women aged more than 35 years (AOR = 11.97, CI: 2.55, 5. 67). Food insecurity was highly prevalent but it was not associated with maternal thinness of pregnant women. The risk of maternal thinness increased as the gestational age increased and this has a great potential of adversely influencing pregnancy outcomes and overall quality of life. PMID- 29188044 TI - Effect of soy protein isolate on the functional, pasting, and sensory acceptability of cassava starch-based custard. AB - Fortification of custard powder (CP) with protein from cheap sources such as soybean could potentially improve its nutritive value but may alter its functional and sensory properties. This study was therefore conducted to determine the effect of soy protein isolate (SPI) inclusion (0%-20%) on some functional and sensory properties of cassava starch-based CP. Functional, pasting, and sensory acceptability were determined using standard methods. Increase in soy protein isolate significantly (p < .05) decreased dispersibility, packed bulk density, swelling power, peak, trough, breakdown, final, and setback viscosities, but increased least gelation concentration, water absorption capacity, and solubility index. This study further showed that despite increasing addition of SPI up to 20%, sensory acceptability of the cassava starch-based CP formulations did not differ significantly, and most of them had very similar acceptability when compared to that of corn starch-based CP. PMID- 29188045 TI - Effects of thermal processing on the nutritional and functional properties of defatted conophor nut (Tetracarpidium conophorum) flour and protein isolates. AB - Conophor nut (Tetracarpidium conophorum) was processed using different heat treatments to explore its full potential as food ingredients. The raw, boiled, and toasted nuts were defatted and the proteins isolated by alkaline solubilization and isoelectric precipitation. The variously processed nuts were analyzed for the proximate and amino acid compositions, and functional properties. The protein contents of the isolate ranges between 86.86 g/100g and 87.74 g/100 g, about 1.5-fold higher than those of the defatted flour samples. The essential amino acids of the isolates ranged between 40.57%-41.55%. Glutamic acid, aspartic acid, and arginine were the most predominant amino acids, while methionine and lysine were the first and second limiting amino acids, respectively. The protein efficiency ratio, biological values as well as the functional properties of the proteins were improved with processing. These properties may enhance the potential use of conophor nut protein isolates as high quality protein ingredient in food systems. PMID- 29188046 TI - Influence of particle size and extraction solvent on antioxidant properties of extracts of tea, ginger, and tea-ginger blend. AB - The influence of particle size and extraction solvent on the antioxidant properties of aqueous and ethanolic extracts of tea (Camellia sinensis), ginger (Zingiber officinale), and tea-ginger (2:1) blend was investigated. The powder sizes studied were 0.425, 0.710, and 1.180 mm. Extracts were analyzed for DPPH radical scavenging activity, ABTS radical scavenging activity, total phenol content (TPC), iron chelating activity, total flavonoid content, and peroxide scavenging activity. The powder with the lowest particle size of 0.425 mm tends to produce aqueous extracts of tea, ginger, and tea-ginger with highest antioxidant content. At this lowest particle size all the antioxidant properties assayed were maximized. The TPC of aqueous extracts obtained from the 0.425 mm tea, ginger, and tea-ginger powders were 685.44 +/- 175, 283.58 +/- 19, and 483.02 +/- 176 mg gallic acid equivalent (GAE) L-1, respectively. The TPC of aqueous extracts obtained from the 0.710 mm tea, ginger, and tea-ginger powders were 679.06 +/- 169, 208.94 +/- 147, and 400.10 +/- 130 mg GAE L-1, respectively. However, for the aqueous ethanolic and ethanolic extracts, the particle size that maximized the antioxidant extraction varied depending on the antioxidant property that was being assayed. The study suggests that particle size influences the extraction of antioxidants. Also, the optimum powder size that would maximize antioxidant extraction is dependent on the solvent used and the antioxidant property being measured. PMID- 29188047 TI - Fatty acid profiles of the main lipid classes of green seaweeds from fish pond aquaculture. AB - The lipid composition of five species of green seaweeds (Chaetomorpha linum, Rhizoclonium riparium, Ulva intestinalis, Ulva lactuca, and Ulva prolifera) grown in fish pond aquaculture systems was studied. In particular, the overall fatty acid (FA) profile and the FA profile of each main lipid class found in these seaweed species were thoroughly analyzed. It was found that every seaweed had a specific FA profile, whose specificities were rendered more obvious with the study of the FA profile per lipid class. However, between U. lactuca and U. intestinalis, there were only minor differences. Nonetheless, it was possible to identify significant differences between the palmitic acid content in the phospholipid (PL) and glycolipid (GL) classes of each seaweed. A clear distinction between the FA profiles of R. riparium and C. linum, which belong to the Cladophorales order, and those of Ulva genus, Ulvales order, was also determined. Moreover, there were also differences among lipid classes, yielding large contrasts between PLs + GLs and triacylglycerols (TAGs) as well as between monoacylglycerols (MAGs) and free fatty acids (FFAs). This study also found evidence supporting the location of particular FAs in specific TAG positions. FA profiles have the potential to be used as a chemotaxonomic tool in green seaweeds, providing a simple method to check authenticity of seaweed used as food. PMID- 29188048 TI - Effects of cooking techniques on fatty acid and oxylipin content of farmed rainbow trout (Oncorhynchus mykiss). AB - The aim of this study was to investigate the effect of various cooking techniques on the fatty acid and oxylipin content of farmed rainbow trout. Rainbow trout is an excellent source of long-chain omega-3 (n-3) polyunsaturated fatty acids (PUFA) which have beneficial health effects. Fillets of 2-year-old farmed rainbow trout were baked, broiled, microwaved, or pan-fried in corn (CO), canola (CaO), peanut (PO), or high oleic sunflower oil (HOSO). Fatty acids and oxidized lipids were extracted from these samples and their respective raw fillet samples. Fatty acid content was determined using gas chromatography and oxylipin content by mass spectroscopy. The values obtained from each cooking method were compared to those obtained from the respective raw fillets using paired t tests. PUFA content was not altered when samples were baked, broiled, microwaved, or pan-fried in CO or CaO. Pan-frying in PO reduced alpha-linolenic acid (18:3n-3), eicosadienoic acid (20:2n-6), and dihomo-gamma-linolenic acid (20:3n-6), while pan-frying in HOSO reduced 18:3n-3, eicosapentaenoic acid (20:5n-3), docosapentaenoic acid (22:5n 3), docosahexaenoic acid (22:6n-3), linoleic acid (18:2n-6), 18:3n-6, 20:2n-6, 20:3n-6, docosatrienoic acid (22:2n-6), and adrenic acid (22:4n-6) compared to raw fish. Cooking decreased the omega-6 (n-6) PUFA-derived oxylipins, but caused no change in 20:5n-3 or 22:6n-3-derived oxylipins of the fillets. In conclusion, pan-frying was the only cooking method to alter the fatty acid content of the fillets, while observed changes in oxylipin content varied by cooking method. As the physiological impact of oxylipins is currently unknown, these results suggest that the cooking methods which optimize the consumption of n-3 PUFA from rainbow trout are baking, broiling, microwaving, or pan-frying in CO, CaO, or PO.

AB - Malnutrition is one of the foremost causes of death among children below 5 years in developing countries. Development of nutrient-dense food formulations using locally available crops has been proposed as a means to combat this menace. This study optimized the extrusion process for the production of a nutritious amaranth based porridge flour. Least cost formulations containing grain amaranth, groundnut, iron-rich beans, pumpkin, orange-fleshed sweet potato, carrot, and maize were developed and evaluated by a sensory panel (n = 30) for acceptability using the 9-point hedonic scale. Extrusion process of the most acceptable porridge flour was optimized by response surface methodology (RSM). Barrel temperature (130-170 degrees C) and feed moisture content (14%-20%) were the independent variables which significantly (p < .05) affected in vitro protein digestibility, vitamin A retention, total polyphenol, phytic content, and iron and zinc extractabilities. Optimization of the extrusion process improved the nutritional quality of the instant flour. PMID- 29188050 TI - Effects of household washing on bacterial load and removal of Escherichia coli from lettuce and "ready-to-eat" salads. AB - Customer demands for fresh salads are increasing, but leafy green vegetables have also been linked to food-borne illness due to pathogens such as Escherichia coli O157:H7. As a safety measure, consumers often wash leafy vegetables in water before consumption. In this study, we analyzed the efficiency of household washing to reduce the bacterial content. Romaine lettuce and ready-to-eat mixed salad were washed several times in flowing water at different rates and by immersing the leaves in water. Lettuce was also inoculated with E. coli before washing. Only washing in a high flow rate (8 L/min) resulted in statistically significant reductions (p < .05), "Total aerobic count" was reduced by 80%, and Enterobacteriaceae count was reduced by 68% after the first rinse. The number of contaminating E. coli was not significantly reduced. The dominating part of the culturable microbiota of the washed lettuce was identified by rRNA 16S sequencing of randomly picked colonies. The majority belonged to Pseudomonadaceae, but isolates from Enterobacteriaceae and Staphylococcaceaceae were also frequently found. This study shows the inefficiency of tap water washing methods available for the consumer when it comes to removal of bacteria from lettuce. Even after washing, the lettuce contained high levels of bacteria that in a high dose and under certain circumstances may constitute a health risk. PMID- 29188051 TI - The science behind autologous fat grafting. AB - Introduction: Adipose grafting has undergone significant changes over time. Many different techniques have been followed by trying to improve the quality of the lipoaspirate and the survival of the fat graft after implantation. Material and methods: The purpose of this review is to analyse the historical evolution of the surgical harvesting and implant technique, describing the changes that have brought significant improvements, revolutionizing the aesthetic and functional results obtainable. Results: A standard fat grafting technique is commonly performed in three stages: harvesting of adipose tissue from a suitable donor site; processing of the lipoaspirate to eliminate cellular debris, acellular oil and excess of infiltrated solution, reinjection of the purified adipose tissue. The most widely used surgical technique was described by Coleman. He modified and corrected the methods and results of his predecessors and proposed an atraumatic protocol for the treatment of adipose tissue.He reported that the key to successful fat grafting lies in the technique. In addition, he noticed that adipose tissue was not only a good filler, but improved the quality of the skin. In fact, fat grafts demonstrated to have not only dermal filler properties but also regenerative potential owing to the presence of stem cells in fat tissue. Conclusion: Adipose tissue, actually, is the closest to the ideal filler because it is readily available; easily obtainable, with low donor-site morbidity; repeatable; inexpensive; versatile; and biocompatible. There is an abundance of literature supporting the efficacy of fat grafting in both aesthetic and reconstructive cases. Recent studies have shown the utility of adipose-derived stem cells in the improvement of wound healing, describing their ability to regenerate soft tissues and their remodelling capacity provided by their unique cytokine and growth factor profiles.Despite ongoing concerns about survival and longevity of fat grafts after implantation and unpredictability of long-term outcome, fat has been successfully used as a filler in many differ clinic situation. PMID- 29188052 TI - Biological roles of hepatocyte growth factor-Met signaling from genetically modified animals. AB - Hepatocyte growth factor (HGF) is produced by stromal and mesenchymal cells, and it stimulates epithelial cell proliferation, motility, morphogenesis and angiogenesis in various organs via tyrosine phosphorylation of its cognate receptor, Met. The HGF-Met signaling pathway contributes in a paracrine manner to the development of epithelial organs, exerts regenerative effects on the epithelium, and promotes the regression of fibrosis in numerous organs. Additionally, the HGF-Met signaling pathway is correlated with the biology of cancer types, neurons and immunity. In vivo analyses using genetic modification have markedly increased the profound understanding of the HGF-Met system in basic biology and its clinical applications. HGF and Met knockout (KO) mice are embryonically lethal. Therefore, amino acids in multifunctional docking sites of Met have been exchanged with specific binding motifs for downstream adaptor molecules in order to investigate the signaling potential of the HGF-Met signaling pathway. Conditional Met KO mice were generated using Cre-loxP methodology and characterization of these mice indicated that the HGF-Met signaling pathway is essential in regeneration, protection, and homeostasis in various tissue types and cells. Furthermore, the results of studies using HGF overexpressing mice have indicated the therapeutic potential of HGF for various types of disease and injury. In the present review, the phenotypes of Met gene modified mice are summarized. PMID- 29188053 TI - Ex vivo regenerative effects of a spring water. AB - Previous experiments by our group have indicated the regenerative effects of a spring water (Comano), which was possibly associated with the native non pathogenic bacterial flora. The present study aimed to confirm these regenerative properties in a human ex vivo experimental model in the context of physiological wound healing. Human 6-mm punch skin biopsies harvested during plastic surgery sessions were injured in their central portion to induce skin loss and were cultured in either conventional medium (controls) or medium powder reconstituted with filtered Comano spring water (treated samples). At 24, 48 and 72 h the specimens were observed following staining with hematoxylin and eosin, Picrosirius Red, orcein and anti-proliferating cell nuclear antigen. Compared with the controls, the treated samples exhibited reduced overall cell infiltration, evidence of fibroblasts, stimulation of cell proliferation and collagen and elastic fiber regeneration. In the spring water, in addition to 12 resident non-pathogenic bacterial strains exhibiting favorable metabolic activities, more unknown non-pathogenic species are being identified by genomic analysis. In the present study, the efficacy of this 'germ-free', filtered spring water in wound regeneration was indicated. Thus, the Comano spring water microbiota should be acknowledged for its regenerative properties. PMID- 29188054 TI - Solitary pulmonary capillary hemangioma presents as ground glass opacity on computed tomography indicating adenocarcinoma in situ/atypical adenomatous hyperplasia: A case report. AB - Solitary pulmonary capillary hemangioma (SPCH) is a rare type of benign lung tumor, which must be distinguished from early lung cancer and precancerous lesions of the lung that manifest in a similar way upon imaging. The current study describes a case of SPCH and a review of the literature is performed. The patient was a 40-year-old Chinese woman who was referred to the Liaoning Cancer Hospital and Institute (Shenyang, China) in October, 2015 with a cough without obvious inducement. Computed tomography (CT) demonstrated pure ground glass opacity (GGO) in the right upper lung. Following systemic anti-inflammatory therapy over 6 months, the lesion did not exhibit any change on CT and was suspected to be an adenocarcinoma in situ (AIS) or atypical adenomatous hyperplasia (AAH). Video-assisted thoracic surgery wedge resection was subsequently performed. Frozen section diagnosis revealed a benign tumor without atypical epithelial cells. Subsequent to surgery, paraffin sections demonstrated that the tumor contained narrow alveolar cavities, thickened alveolar septa and a clear boundary separating it from healthy lung tissue. Furthermore, the proliferation lumens in the alveolar septa were lined with a single layer of flat cells. Immunohistochemical staining revealed that the flat cells were positive for cluster of differentiation CD31 and CD34, and negative for thyroid transcription factor-1 and cytokeratin. The proliferation of capillary vessels lead to the thickened alveolar septa and the tumor was diagnosed as SPCH. When imaging examination demonstrates a GGO in lung, SPCH must be considered in the differential diagnosis of AIS/AAH. As the prognosis of these lesions is entirely different, a pathological examination must be conducted to ensure a correct diagnosis. PMID- 29188055 TI - Aberrant expression of interleukin-10 and activation-induced cytidine deaminase in B cells from patients with Behcet's disease. AB - Despite extensive studies, the pathogenesis of Behcet's disease (BD) remains unclear. In particular, the roles of B cells in patients with BD have not been elucidated. Activation-induced cytidine deaminase (AID) is a critical enzyme for immunoglobulin (Ig) heavy chain class switching and somatic hypermutation in B cells and the abnormal expression of AID in various immune conditions has previously been studied. B10 cells, an interleukin (IL)-10-secreting subset of regulatory B cells, function to downregulate inflammation and autoimmunity. Thus, in the present study, the relevance of B cells in patients with BD was investigated. The plasma levels of IL-10 and IgA and the proportions of cluster of differentiation (CD)43+ B cells, excluding naive B cells, were measured in 16 patients with BD and 16 age- and sex-matched healthy controls (HCs). Additionally, the mRNA levels of IL-10 and AID were assessed in B cells from fresh peripheral blood samples of the BD patients and HCs. The plasma level of IL 10 in patients with BD did not differ significantly from that in HCs. Similarly, there was no significant difference in the plasma level of IgA, although a slight increase was observed in patients with BD compared with that in HCs. There were no differences in CD43+CD19+ B cell numbers between patients with BD and HCs. However, IL-10 mRNA levels were significantly reduced (P<0.05), while AID mRNA levels were significantly increased (P<0.01) in the B cells of patients with BD compared with those in HCs. These results provide insight into the role of B cells in patients with BD. PMID- 29188056 TI - Molecular cloning, expression, purification and functional characterization of an antifungal cyclophilin protein from Panax ginseng. AB - Cyclophilins (CyPs), a member of peptidyl-prolyl cis-trans isomerases (PPIases), are ubiquitously distributed in organisms such as bacteria, yeast, plants and animals. CyPs have diverse biological functions, with some exhibiting antifungal and antiviral activities. In this study, Panax ginseng cyclophilin (pgCyP), a novel gene encoding an antifungal protein from Panax ginseng, was cloned, and its protein product was expressed in Escherichia coli, and then fractionated by affinity chromatography. The open reading frame of the pgCyP full-length coding sequence was found to encode a single-domain CyP-like protein of 174 amino residues with a calculated molecular weight of 18.7 kDa. The pGEX system was used to express pgCyP fused to glutathione S-transferase. After affinity purification, the protein showed a strong fungal resistance effect on Phytophthora cactorum. In addition, pgCyP showed high PPIase activity. To the best of our knowledge, the present study is the first successful effort to clone and characterize a CyP-like protein gene from Panax ginseng. PMID- 29188057 TI - Subungual onychomycosis due to Aspergillus niger mimicking a glomus tumor: A case report. AB - Onychomycosis is a common nail infection caused by dermatophytes, while non dermatophytes including Aspergillus spp. are causes of nail onychomycosis. Aspergillus niger is not common as a cause of nail onychomycosis. In the current study we present a 60-year-old woman with subungual onychomycosis due to Aspergillus niger mimicking a glomus tumor. Physical examination revealed right thumb had a black color of nail bed. Localized tenderness and severe pain were observed. However, the cold sensitivity test, Loves pin test and Hildreths test were negative. On radiograph, bone erosion was found in a part of distal phalanx at the right thumb. Magnetic resonance imaging identified a mass at the subungual space, which exhibited low signal intensity on T1-weighted images and high signal intensity on T2-weighted images. The differential diagnosis included glomus tumor and infection. The histological findings demonstrated dichotomous septate hyphae. The culture was positive for Aspergillus niger. The results suggested that when physical examination is not typical for a glomus tumor, other diseases may be considered. Additionally, frozen section diagnosis may be useful. PMID- 29188058 TI - Alterations in three biomarkers (estrogen receptor, progesterone receptor and human epidermal growth factor 2) and the Ki67 index between primary and metastatic breast cancer lesions. AB - In recurrent breast cancer, the tumor phenotype, as assessed by estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor 2 (HER2) status, occasionally changes. This change, in addition to the Ki67 index were evaluated at sites of recurrence and the correlation between changes in tumor phenotype and survival were assessed in breast cancer patients. Comparisons in pathological parameters between primary and metastatic lesions were drawn between ER, PR, HER2, and the Ki67 index in 70 patients with recurrent breast cancer. The association between changes in tumor phenotype and patient survival was assessed. The hormone receptor status changed from positive, in the primary lesions, to negative, in the metastatic lesions in 19.8% (ER) and 39.5% (PR) of patients, respectively. Conversion from negative to positive status was confirmed in 27.2% (ER) and 31.2% (PR) of patients, respectively. A change in HER2 status from negative (primary lesion) to positive (metastatic lesion) occurred in seven patients (10%). The mean Ki67 index of primary lesions with positive hormone receptor status was significantly lower than at sites of recurrence with any hormone receptor status, from 10.9+/-9.8 standard deviation (SD) to 22.9+/-18.6 (P=0.031) and 12.2+/-10.5 SD to 27.4+/-20.9 (P=0.023), for ER and PR, respectively. The mean overall survival of patients with ER status conversion from positive to negative was 7.4+/-1.2 standard error (SE) years, and 14.8+/-1.4 SE years for patients who retained positive ER status (P=0.005, log-rank), with a hazard ratio of 3.44 (95% confidence interval, 1.36-8.33). This difference in survival based upon change in ER status was similarly observed in patients with PR status conversion in the same direction. Thus, ER and PR status conversion at the time of recurrence strongly impact survival, particularly if the change is from positive (primary lesion) to negative (metastatic lesion). Monitoring the biological behavior of breast cancer may benefit a patient by allowing for a novel personalized treatment strategy. PMID- 29188059 TI - Efficacy of high dose vitamin D supplementation in improving serum 25 hydroxyvitamin D among laboratory personnel working at the Nepal National Center for Rheumatic Diseases. AB - Vitamin D deficiency is a highly prevalent condition worldwide. However, few studies have been conducted to examine the vitamin D status of laboratory personnel and the correlation between vitamin D deficiency and working conditions. The aim of the present study was to assess changes in serum 25 hydroxyvitamin D [25(OH)D] concentration with a weekly dose of oral cholecalciferol (60,000 IU) for two months. The prospective, open-label, interventional study was conducted from January 2016 to March 2016 at the National Centre for Rheumatic Diseases, Kathmandu, Nepal. The serum level of 25(OH)D in 19 healthy laboratory volunteers was measured at baseline and following the 2-month regimen with cholecalciferol supplement at 60,000 IU (1,500 ug)/week in oral tablet form. At baseline the mean serum 25(OH)D level was 10.31+/-7.78 ng/ml, which was increased following completion of the course of oral cholecalciferol to 59.78+/-14.74 ng/ml. This difference in the mean serum level of 25(OH)D compared with baseline was significant to P<0.001. These results indicate that vitamin D deficiency is prevalent among laboratory workers, and that high dose vitamin D3 (60,000 IU cholecalciferol) in tablet form may be effective in achieving sufficient serum 25(OH)D among laboratory personnel who tend to have lower baseline serum 25(OH)D. In conclusion, vitamin D deficiency may be common among laboratory workers, and guidelines should be formulated to implement vitamin D supplementation among laboratory personnel, as well as indoor workers, in Nepal. PMID- 29188060 TI - Effects of MPO-463G/A and -129G/A polymorphisms on coronary artery disease risk and patient survival in a Turkish population. AB - Myeloperoxidase (MPO) is an oxidative hemoprotein compound expressed in polymorphonuclear leukocytes that contributes to inflammatory responses. Coronary artery disease (CAD), as the most prevalent form of heart disease, is considered to originate from an interaction between genetic and environmental factors. In the present study, the potential associations between MPO-463G/A and -129G/A polymorphisms with CAD were investigated in a Turkish population using a polymerase chain reaction-based restriction fragment length polymorphism (RFLP) assay technique. To the best of our knowledge, the study was the first to examine the association of MPO-463G/A and -129G/A with patient survival rate in a Turkish population. The study population consisted of 201 patients with CAD and 201 healthy controls. The results indicated that there was a significant association of the GA genotype of MPO-463G/A with the case population (P=0.048). Meanwhile, in the patients with CAD, the frequency distributions of the MPO-129A allele (P=0.006) and GA genotype (P=0.001) were significantly increased compared with the G allele and GG genotype, respectively, in CAD patients. Additionally, compared with the GG genotype, the frequency distribution of MPO-129A was significantly increased in the patient group regarding smoking status (P=0.001) and the presence of hypercholesterolemia (P=0.028). However, survival analysis did not detect an effect of either polymorphism on the survival rate of the CAD patients (P>0.05). Therefore, the MPO-129GA genotype may be a significant risk factor for the development of CAD. PMID- 29188061 TI - Effect of Coriolus versicolor glucan on the stimulation of cytokine production in sarcoma-180-bearing mice. AB - Coriolus versicolor (CV) contains high levels of bioactive compounds, including the glucan (1->6)-alpha-D-glucopyranosyl. However, there is a lack of data regarding the potential effect of this CV glucan (CVG) on the stimulation of cytokine production. The present study evaluated the effect of CVG on the stimulation of cytokine production in sarcoma-180-bearing mice. Mice were treated with three doses of CVG (40, 100 or 200 mg/kg body weight) for nine days, after which serum levels of cytokines, namely interleukin (IL)-2, -4, -6, -10, -17A and interferon (IFN)-alpha and -gamma, were investigated by ELISA. CVG significantly promoted the secretion of IL-2, -4, -6, -10, -17A and IFN-alpha and -gamma at the doses of 100 (P<0.05) and 200 (P<0.01) mg/kg, but not at 40 mg/kg (P>0.05), when compared with cyclophosphamide treatment, as a positive control. Additionally, cytokine production associated with T helper (Th)2 and Th17 cells was enhanced compared with that of Th1 cytokines, and the immunomodulatory function of CVG appeared to be IL-10-dependent. These results demonstrate that CVG may stimulate the production of cytokines and serve as a Th2/IL-10-dependent immunomodulator, and thus has promise in supporting cancer therapies. PMID- 29188064 TI - "Streptomyces massilialgeriensis" sp. nov., a new bacterial species isolated from an extremely saline soil collected from the dry lake of Ank el Djamel in Algeria. AB - We report here the main characteristics of "Streptomyces massilialgeriensis" strain S35T (CSUR = P3927), a new bacterial species within the Streptomyces genus, isolated from an extremely saline soil sample collected from the site of Garaet Ank Djemel in the Wilaya of Oum El Bouaghi, Algeria. PMID- 29188062 TI - Human aqueous humor levels of transforming growth factor-beta2: Association with matrix metalloproteinases/tissue inhibitors of matrix metalloproteinases. AB - The present study aims to investigate the association of transforming growth factor-beta2 (TGF-beta2) and matrix metalloproteinases (MMPs), MMP-2 and MMP-3, and tissue inhibitors of matrix metalloproteinases (TIMPs), TIMP-1, TIMP-2 and TIMP-3 in the aqueous humor of patients with high myopia or cataracts. The levels of TGF-beta2 and MMPs/TIMPs were measured with the Luminex xMAP Technology using commercially available Milliplex xMAP kits. The association between TGF-beta2 and MMPs/TIMPs levels was analyzed using the Spearmans correlation test. The levels of TGF-beta2 were identified to be positively correlated with the levels of TIMP 1 and TIMP-3 (TIMP-1: r=0.334; P=0.007; TIMP-3: r=0.309; P=0.012). The levels of MMP-2, MMP-3 and TIMP-2 did not significantly correlate with TGF-beta2 levels (P>0.05). A positive correlation was identified between TGF-beta2 and TIMPs in the aqueous humor of human eyes with elongated axial length. It appears that TGF beta2 stimulates the expression of TIMPs as a compensatory reaction to the development of high myopia. PMID- 29188063 TI - High rates of nontuberculous mycobacteria isolation from patients with presumptive tuberculosis in Iran. AB - Nontuberculous mycobacteria (NTM) can cause disease which can be indistinguishable from tuberculosis (TB), posing a diagnostic and therapeutic challenge, particularly in low- and middle-income settings. We aimed to investigate the mycobacterial agents associated with presumptive clinical pulmonary TB in Iran. A total of 410 mycobacterial isolates, obtained between March 2014 and January 2016, from 7600 clinical samples taken from consecutive cases of presumptive diagnosis of TB were identified. Phenotypic and molecular tests were used to identify the isolated organisms to the species level. Single locus and multilocus sequence analysis based on 16S rRNA, rpoB, hsp65 and ITS locus were used to confirm the results. Of 410 consecutive strains isolated from suspected TB subjects, 62 isolates (15.1%) were identified as NTM. Patients with positive NTM cultures met American Thoracic Society diagnostic criteria for NTM disease. Mycobacterium simiae was the most frequently encountered (38.7%), followed by Mycobacterium fortuitum (19.3%), M. kansasii (17.7%) and M. avium complex (8.0%). Isolation of NTM, including M. simiae, from suspected TB cases is a serious public health problem and merits further attention by health authorities, physicians and microbiologists. PMID- 29188065 TI - High circulating plasma dipeptidyl peptidase- 4 levels in non-obese Asian Indians with type 2 diabetes correlate with fasting insulin and LDL-C levels, triceps skinfolds, total intra-abdominal adipose tissue volume and presence of diabetes: a case-control study. AB - Aim: To evaluate circulating plasma dipeptidyl peptidase-4 (DPP4) levels in non obese Asian Indians with type 2 diabetes mellitus (T2DM), and to correlate these with metabolic profile and measures of anthropometry, skinfolds, abdominal adipose tissue depots, pancreatic volume, and liver span. Methodology: Non-obese (body mass index (BMI) <25 kg/m2) patients with T2DM (cases, n=93), diagnosed within 1 year from recruitment, on metformin therapy and BMI-matched, and non diabetic subjects (controls, n=40) were compared. Measurements of blood glucose, glycosylated hemoglobin, plasma insulin levels, lipid profile, hepatic transaminases and plasma DPP4 levels, and quantification of abdominal fat depots, pancreatic volume and liver span (MRI scan), were done. Results: Significantly higher (p<0.001) circulating plasma DPP4 levels were observed in cases as compared to controls. Specifically, in patients with T2DM with non-alcoholic fatty liver disease (NAFLD) (n=48), the mean plasma DPP4 level (52.6+/-27.8 ng/mL) was significantly higher (p<0.05) as compared with those without NAFLD (n=43; 47+/-28.3 ng/mL). Significant positive correlation was observed for circulating plasma DPP4 levels with waist-to-hip ratio, total intra-abdominal adipose volume, and liver span. Fasting serum insulin, low-density lipoprotein cholesterol (LDL-C), triceps skinfolds, total intra-abdominal adipose tissue volume and presence of T2DM were significant determinants of circulating plasma DPP4 levels. Conclusion: Non-obese Asian Indian patients with T2DM and on metformin therapy have significantly higher circulating plasma DPP4 levels as compared to non-obese non-diabetic controls, and these levels correlate with fasting insulin and LDL-C levels, upper limb subcutaneous adipose tissue, intra abdominal adiposity and presence of diabetes. PMID- 29188066 TI - Aeromonas wound infection in a healthy boy, and wound healing with polarized light. AB - Introduction. At emergency departments, history taking is often very brief. We present a case of an Aeromonas wound infection, that illustrates the importance of careful history taking. We also report the first successful use of polarized light as additional therapy for healing of this infectious wound. Case presentation. A healthy boy was diagnosed with a wound infection, after a fall onto rocks. At first, it remained unmentioned that there had been contact with ditchwater, so he was treated with amoxicillin-clavulanic acid. Only after the finding of an Aeromonas strain in the wound culture, and treatment with a fluoroquinolone, did he recover. Wound healing was aided with the use of polarized light, and with good effect. To our knowledge, this is the first report on the effect of polarized light on the healing of infectious wounds. Conclusion. Careful history taking is essential for adequate empiric therapy when faced with wounds and wound infections. Aeromonas infections are associated with water exposure, and should be treated with fluoroquinolones. Polarized light seems to have a good result on healing of infectious wounds. PMID- 29188067 TI - Isolation and characterization of Leptospira interrogans serovar Copenhageni from a dog from Saint Kitts. AB - Introduction. Leptospirosis is a zoonotic bacterial disease of global distribution affecting humans and animals. The initial phase of leptospirosis resembles many other febrile illness and due to its broad and biphasic clinical manifestations, selection and implementation of appropriate diagnostic tests can be challenging. Case presentation. This report describes a case investigation of a 14 weeks old male, orphan puppy, presented with generalised jaundice, anemia, weakness, and anorexia. Clinical abnormalities included the evidence of renal and hepatic failure. Antemortem and postmortem diagnostic investigations were conducted to identify the cause of illness. PCR testing and culture of blood was positive for Leptospira sp. Necropsy followed by histopathology evaluation revealed lesions compatible with liver and kidney damage consisting of marked diffuse hepatocellular dissociation, acute renal tubular necrosis, and mild interstitial nephritis. Conclusion. Multiple diagnostic techniques including bacterial isolation confirmed Leptospira infection in this puppy. Whole genome sequencing and analysis identified the Leptospira sp. isolated from this puppy as Leptospira interrogans serovar Copenhageni. To our knowledge, this case report describes the first isolation of Leptospira from Saint Kitts. This case highlights the usefulness of including multiple diagnostic tests for the diagnosis and epidemiological investigation of Leptospira infection. Accurate diagnosis followed by timely intervention can prevent case fatality and mortality in infected patients. PMID- 29188068 TI - 32-week premature rupture of membranes caused by oropharyngeal microbiota. AB - Introduction. Preterm premature rupture of membranes (PPROM) usually has a multifactorial etiology that is often unknown, although the most frequently reported cause is infection by group B Streptococcus. Therefore, the etiology of PPROM, although probably infectious, remains unknown in most cases. This case describes a PPROM caused by infection from oropharyngeal microbiota. Case presentation. We report the case of a 26-yr-old pregnant woman. The gestational age was 32 weeks+5 days. Examinations in the emergency department revealed the release of clear amniotic fluid and a closed multiparous cervix with a length of 22 mm. Endocervical culture evidenced the growth of Staphylococcus aureus, serogroup B Neisseria meningitidis and Haemophilus influenzae. Conclusion. Preventive antibiotic therapy should consider: opportunistic infections by normal genital microbiota, infections due to sexual activity, opportunist microorganisms derived from oral sex, and the hematogenous spread of oral bacteria. PMID- 29188069 TI - Simultaneous isolation of Chryseobacterium gleum from bloodstream and respiratory tract: first case report from India. AB - Introduction. Species of the genus Chryseobacterium are emerging healthcare associated pathogens, often colonizing the hospital environment. There are no clear guidelines available for antimicrobial susceptibility of this organism. In this report we present the first case, to our knowledge, of simultaneous central line-associated bloodstream infection (CLABSI) and ventilator-associated pneumonia (VAP) due to Chryseobacterium gleum from India. Case presentation. A 62 years old man with a history of a road traffic accident 1 month previously was referred to our center for further management. He developed features of sepsis and aspiration pneumonia on day 3 of admission. Four blood cultures (two each from central and peripheral lines) and two tracheal aspirate cultures grew pure yellow colonies of bacteria. Both matrix assisted laser desorption ionization time of flight mass spectrometry, (MALDI-TOF MS; bioMerieux, Marcy-L'Etoile, France,) and BD Phoenix (BD Biosciences, Maryland, USA) identified the organism as C. gleum. However, BD Phoenix failed to provide MIC breakpoints. The isolates of C. gleum both from blood and tracheal aspirate showed identical susceptibility patterns: resistant to cephalosporins and carbapenems and susceptible to ciprofloxacin, levofloxacin, amikacin, trimethoprim+sulfamethoxazole, piperacillin-tazobactam, cefoperazone-sulbactam, doxycycline, minocycline and vancomycin. Following levofloxacin therapy, the fever responded within 48 h and procalcitonin levels decreased without removal of the central line or endotracheal tube. However, the patient developed sudden cardiac arrest on day 10 of treatment and could not be resuscitated. Conclusion. Rapid and accurate identification of C. gleum in the laboratory, preferably based on MALDI-TOF, is essential for guiding therapy. C. gleum responds well to fluoroquinolones without the need to remove indwelling catheters. PMID- 29188070 TI - The first case report of septic abortion resulting from beta-lactamase-negative ampicillin-resistant non-typeable Haemophilus influenzae infection. AB - Introduction. This is the first case report of septic abortion due to beta lactamase-negative ampicillin-resistant (BLNAR) non-typeable Haemophilus influenzae infection. In Japan, BLNAR H. influenzae is widespread and has become a clinical concern, especially in paediatrics and otolaryngology, but H. influenzae has not been previously recognized as a causative agent of obstetric or gynaecological infection. Case presentation. A 31-year-old pregnant woman presented at 17 weeks and 6 days of gestation with a high fever; she was admitted with a diagnosis of threatened premature delivery. Despite tocolytic treatment, she aborted spontaneously 2 h after admission and then entered septic shock. BLNAR H. influenzae was detected in both blood and vaginal cultures. Her condition gradually improved after several days of treatment with cefotaxime, and she was ultimately discharged without sequelae or complaints. Conclusion. Although penicillin with a beta-lactamase inhibitor is currently recommended for the treatment of septic abortion, this combination will probably lead to treatment failure in the case of BLNAR H. influenzae infection. As this study reveals, H. influenzae can cause septic abortion; hence, future efforts should be undertaken to detect and therapeutically target this pathogen during pregnancy. PMID- 29188071 TI - Postoperative Tropheryma whipplei endophthalmitis - a case report highlighting the additive value of molecular testing. AB - Introduction.Tropheryma whipplei is the causative agent of Whipple's disease. Gastrointestinal and lymphatic tissues are affected in the majority of cases, resulting in diarrhoea, malabsorption and fever. Here, we report a rare case of ocular manifestation in a patient lacking the typical Whipple symptoms. Case presentation. A 74-year-old Caucasian female presented with blurred vision in the right eye over a period of 1-2 months, accompanied by stinging pain and conjunctival hyperaemia for the last 2 days. Upon admission, visual acuity was hand motion in the affected eye. Ophthalmological examination showed typical signs of intraocular inflammation. Diagnostic and therapeutic pars plana vitrectomy including vitreous biopsy and intravitreal instillation of vancomycin and amikacin was performed within hours of initial presentation. Both microscopic analysis and microbial cultures of the vitreous biopsy remained negative for bacteria and fungi. The postoperative antibiotic regime included intravenous administration of ceftriaxone in combination with topical tobramycin and ofloxacin. Due to the empirical therapy the inflammation ceased and the patient was discharged after 5 days with cefpodoxime orally and local antibiotic and steroidal therapy. Meanwhile, the vitreous body had undergone testing by PCR for the eubacterial 16S rRNA gene, which was found to be positive. Analysis of the PCR product revealed a specific sequence of T. whipplei. Conclusion. In our patient, endophthalmitis was the first and only symptom of Morbus Whipple, while most patients with Whipple's disease suffer from severe gastrointestinal symptoms. 16S rDNA PCR should be considered for any intraocular infection when microscopy and standard culture methods remain negative. PMID- 29188072 TI - Systemic Rasamsonia piperina infection in a German shepherd cross dog. AB - Introduction. Infection with the Rasamsonia argillacea species complex represents an emerging problem in human and veterinary medicine with systemic mycoses presenting with significant clinical complications and being a cause of death. Case presentation. In this report, a case of systemic Rasamsonia piperina infection discovered in a 3-year-old male neutered, German shepherd cross dog is described together with the clinical presentation, the course of the disease and diagnosis. This report describes the first case of veterinary mycosis due to R. piperina in Europe and the first case in humans or animals in the UK. Conclusion. Although seemingly rare, R. argillacea species complex infection should be a differential diagnosis for dogs, especially German shepherds with the described presenting signs, and radiographic and ultrasonographic findings. PMID- 29188073 TI - Osteopontin is associated with disease severity and antiphospholipid syndrome in well characterised Swedish cases of SLE. AB - Objective: The variety of disease phenotypes among patients with SLE challenges the identification of new biomarkers reflecting disease activity and/or organ damage. Osteopontin (OPN) is an extracellular matrix protein with immunomodulating properties. Although raised levels have been reported, the pathogenic implications and clinical utility of OPN as a biomarker in SLE are far from clear. Thus, the aim of this study was to characterise OPN in SLE. Methods: Sera from 240 well-characterised adult SLE cases classified according to the American College of Rheumatology (ACR) and/or the Systemic Lupus International Collaborating Clinics (SLICC) criteria, and 240 population-based controls were immunoassayed for OPN. The SLE Disease Activity Index 2000 (SLEDAI-2K) was used to evaluate disease activity and the SLICC/ACR Damage Index (SDI) to detect damage accrual. Results: Serum OPN levels were in average raised fourfold in SLE cases compared with the controls (p<0.0001). OPN correlated with SLEDAI-2K, especially in patients with a disease duration of <12 months (r=0.666, p=0.028). OPN was highly associated with SDI (p<0.0001), especially in the renal (p<0.0001), cardiovascular (p<0.0001) and malignancy (p=0.012) domains. Finally, OPN associated with coherent antiphospholipid syndrome (APS; p=0.009), and both clinical and laboratory criteria of APS had significant positive impact on OPN levels. Conclusions: In this cross-sectional study, circulating OPN correlates with disease activity in recent-onset SLE, reflects global organ damage and associates with APS. Longitudinal studies to dissect whether serum OPN also precedes and predicts future organ damage are most warranted. PMID- 29188074 TI - Heads-up 3D vision system for retinal detachment surgery.

AB - Duchenne muscular dystrophy (DMD) is a genetic disease characterised by skeletal muscle degeneration and progressive muscle wasting, which is caused by loss-of function mutations in the DMD gene that encodes for the protein dystrophin. Dystrophin has critical roles in myofiber stability and integrity by connecting the actin cytoskeleton to the extracellular matrix. Absence of dystrophin leads to myofiber fragility and contributes to skeletal muscle degeneration in DMD patients, however, accumulating evidence also indicate that muscle stem cells (also known as satellite cells) are defective in dystrophic muscles, which leads to impaired muscle regeneration. Our recent work demonstrated that dystrophin is expressed in activated satellite cells, where it regulates the establishment of satellite cell polarity and asymmetric cell division. These findings indicate that dystrophin-deficient satellite cells have intrinsic dysfunctions that contribute to muscle wasting and progression of the disease. This discovery suggests that satellite cells could be targeted to treat DMD. Here we discuss how these new findings affect regenerative therapies for muscular dystrophies. Therapies targeting satellite cells hold great potential and could have long-term efficiency owing to the high self-renewal ability of these cells.

AB - Gallbladder cancer (GBC), with late diagnosis, rapid disease progression and early metastasis, is a highly aggressive malignant tumor found worldwide. Patients with GBC have poor survival, low curative resection rates and early recurrence. For such a lethal tumor, uncovering the mechanisms and exploring new strategies to prevent tumor progression and metastasis are critically important. Epithelial-to-mesenchymal transition (EMT) has a prominent role in the early steps of tumor progression and metastasis by initiating polarized epithelial cell transition into motile mesenchymal cells. Accumulating evidence suggests that EMT can be modulated by the cooperation of multiple mechanisms affecting common targets. Signaling pathways, transcriptional and post-transcriptional regulation and epigenetic alterations are involved in the stepwise EMT regulatory network in GBC. Loss of epithelial markers, acquisition of mesenchymal markers and dysregulation of EMT-inducing transcription factors (EMT-TFs) have been observed and are associated with the clinicopathology and prognosis of GBC patients. Therefore, EMT may be a detectable and predictable event for predicting GBC progression and metastasis in the clinic. In this review, we will provide an overview of EMT from the clinical evidence to cellular regulatory networks that have been studied thus far in clinical and basic GBC studies. PMID- 29188078 TI - One-shot Synesthesia. AB - Synesthesia is commonly thought to be a phenomenon of fixed associations between an outside inducer and a vivid concurrent experience. Hence, it has been proposed that synesthesia occurs due to additional connections in the brain with which synesthetes are born. Here we show that synesthesia can be a much richer and more flexible phenomenon with a capability to creatively construct novel synesthetic experiences as events unfold in people's lives. We describe here cases of synesthetes who occasionally generate novel synesthetic experience, called one shot synesthesias. These synesthetic experiences seem to share all the properties with the classical synesthetic associations except that they occur extremely rarely, people recalling only a few events over the lifetime. It appears that these one-shots are not created at random but are instead responses to specific life events. We contrast the properties of those rare synesthetic events with other, more commonly known forms of synesthesia that also create novel synesthetic experiences, but at a high rate-sometimes creating novel experiences every few seconds. We argue that one-shot synesthesias indicate that synesthetic associations are by their nature not prewired at birth but are dynamically constructed through mental operations and according to the needs of a synesthetic mind. Our conclusions have implications for understanding the biological underpinnings of synesthesia and the role the phenomenon plays in the lives of people endowed with synesthetic capacities. PMID- 29188077 TI - Orai1, 2, 3 and STIM1 promote store-operated calcium entry in pulmonary arterial smooth muscle cells. AB - Previous studies have demonstrated that besides the classic canonical transient receptor potential channel family, Orai family and stromal interaction molecule 1 (STIM1) might also be involved in the regulation of store-operated calcium channels (SOCCs). An increase in cytosolic free Ca2+ concentration promoted by store-operated Ca2+ entry (SOCE) in pulmonary arterial smooth muscle cells (PASMCs) is a major trigger for pulmonary vasoconstriction and proliferation and migration of PASMCs. In this study, our data revealed the following: (1) in both rat distal pulmonary arteries and PASMCs, chronic hypoxia exposure upregulated the expression of Orai1 and Orai2, without affecting Orai3 and STIM1; (2) either heterozygous knockout of HIF-1alpha in mice or knockdown of HIF-1alpha in PASMCs abolished the hypoxic upregulation of Orai2, but not Orai1, suggesting the hypoxic upregulation of Orai2 depends on HIF-1alpha; and (3) using small interference RNA knockdown strategies, Orai1, 2, 3 and STIM1 were all shown to mediate SOCE in hypoxic PASMCs. Together, these results suggested that the components of SOCCs, including Orai1, 2, 3 and STIM1, may lead to novel therapeutic targets for the treatment of chronic hypoxia-induced pulmonary hypertension. PMID- 29188079 TI - Structure-based design of functionalized 2-substituted and 1,2-disubstituted benzimidazole derivatives and their in vitro antibacterial efficacy. AB - The aim of this present study was to synthesize 2-substituted and 1,2 disubstituted benzimidazole derivatives to investigate their antibacterial diversity for possible future drug design. The structure-based design of precursors 2-(1H-benzimidazol-2-yl)aniline 1, 2-(3,5-dinitro phenyl)-1H benzimidazole 3 and 2-benzyl-1H-benzimidazole 5 were achieved by the condensation reaction of o-phenylenediamine with anthranilic acid, 3,5-dinitrophenylbenzoic acid, and phenylacetic acid, respectively. The precursors 1, 3 and 5, upon reaction with six different electrophile-releasing agents, furnished the corresponding 2-substituted benzimidazole, 2a-f and 1,2-disubstituted benzimidazole derivatives 4a-f and 6a-f, respectively. The structural identity of the targeted compounds was authenticated by elemental analytical data and spectral information from FT-IR, UV, 1H, and 13C NMR. The outcome of the findings from the in vitro screening unveiled 2-benzyl-1-(phenylsulfonyl)-1H-benzimidazole 6b as the most active derivative with lowest MIC value of 15.63 ug/mL. PMID- 29188080 TI - Oxidation characteristics of porous-nickel prepared by powder metallurgy and cast nickel at 1273 K in air for total oxidation time of 100 h. AB - The oxidation behavior of two types of inhomogeneous nickel was investigated in air at 1273 K for a total oxidation time of 100 h. The two types were porous sintered-nickel and microstructurally inhomogeneous cast-nickel. The porous nickel samples were fabricated by compacting Ni powder followed by sintering in vacuum at 1473 K for 2 h. The oxidation kinetics of the samples was determined gravimetrically. The topography and the cross-section microstructure of each oxidized sample were observed using optical and scanning electron microscopy. X ray diffractometry and X-ray energy dispersive analysis were used to determine the nature of the formed oxide phases. The kinetic results revealed that the porous-nickel samples had higher trend for irreproducibility. The average oxidation rate for porous- and cast-nickel samples was initially rapid, and then decreased gradually to become linear. Linear rate constants were 5.5 * 10-8 g/cm2 s and 3.4 * 10-8 g/cm2 s for the porous- and cast-nickel samples, respectively. Initially a single-porous non-adherent NiO layer was noticed on the porous- and cast-nickel samples. After a longer time of oxidation, a non-adherent duplex NiO scale was formed. The two layers of the duplex scales were different in color. NiO particles were observed in most of the pores of the porous-nickel samples. Finally, the linear oxidation kinetics and the formation of porous non-adherent duplex oxide scales on the inhomogeneous nickel substrates demonstrated that the addition of new layers of NiO occurred at the scale/metal interface due to the thermodynamically possible reaction between Ni and the molecular oxygen migrating inwardly. PMID- 29188081 TI - Plaque Characteristics in the Superficial Femoral Artery Correlate with Walking Impairment Questionnaire Scores in Peripheral Arterial Disease: The Walking and Leg Circulation Study (WALCS) III. AB - Purpose: We studied associations of magnetic resonance imaging (MRI)-measured plaque area and relative percent lumen reduction in the proximal superficial femoral artery with Walking Impairment Questionnaire (WIQ) scores and quality of life in people with lower extremity peripheral arterial disease (PAD). Methods: Four-hundred forty-two participants with PAD underwent cross-sectional imaging of the proximal superficial femoral artery with MRI, and completed the WIQ and the Short-Form-12 mental and physical functioning questionnaires. Questionnaires were scored on a 0-100 scale (100=best). Results adjust for age, sex, race, the ankle brachial index (ABI), comorbidities, and other covariates. Results: Adjusting for age, sex, race, ABI, comorbidities, and other covariates, higher mean plaque area was associated with poorer WIQ distance scores (1st quintile (least plaque)-44.8, 2nd quintile-43.3, 3rd quintile-38.9, 4th quintile-34.6, 5th quintile (greatest plaque)-30.6, p trend <0.001) and poorer WIQ speed scores (1st quintile-40.6, 2nd quintile-39.6, 3rd quintile-39.5, 4th quintile-32.8, 5th quintile-33.0, p trend =0.019). Similar associations of higher maximum plaque area, mean lumen reduction, and maximum lumen reduction with poorer WIQ distance and speed scores were observed. Plaque measures were not associated with WIQ stair climbing scores or SF-12 scores. Conclusion: Among participants with PAD, greater plaque burden and smaller lumen area in the proximal superficial femoral artery are associated with poorer walking endurance and slower walking speed as measured by the WIQ, even after adjusting for the ABI. PMID- 29188082 TI - Microarray analyzer based on wide field fluorescent microscopy with laser illumination and a device for speckle suppression. AB - A microarray analyzer was developed to obtain images and measure the fluorescence intensity of microarrays at three wavelengths from 380 nm to 850 nm. The analyzer contains lasers to excite fluorescence, barrier filters, optics to project images on an image detector, and a device for suppressing laser speckles on the microarray support. The speckle suppression device contains a fibre-optic bundle and a rotating mirror positioned in a way to change the distance between the bundle butt and mirror surface during each mirror revolution. The analyzer provides for measurements with accuracy within +/- 5%. Obtaining images at several exposure times allowed a significant expansion in the range of measured fluorescence intensities. The analyzer is useful for high throughput analysis of the same type of microarrays. PMID- 29188083 TI - Increasing the field of view of adaptive optics scanning laser ophthalmoscopy. AB - An adaptive optics scanning laser ophthalmoscope (AO-SLO) set-up with two deformable mirrors (DM) is presented. It allows high resolution imaging of the retina on a 4 degrees *4 degrees field of view (FoV), considering a 7 mm pupil diameter at the entrance of the eye. Imaging on such a FoV, which is larger compared to classical AO-SLO instruments, is allowed by the use of the two DMs. The first DM is located in a plane that is conjugated to the pupil of the eye and corrects for aberrations that are constant in the FoV. The second DM is conjugated to a plane that is located ~0.7 mm anterior to the retina. This DM corrects for anisoplanatism effects within the FoV. The control of the DMs is performed by combining the classical AO technique, using a Shack-Hartmann wave front sensor, and sensorless AO, which uses a criterion characterizing the image quality. The retinas of four healthy volunteers were imaged in-vivo with the developed instrument. In order to assess the performance of the set-up and to demonstrate the benefits of the 2 DM configuration, the acquired images were compared with images taken in conventional conditions, on a smaller FoV and with only one DM. Moreover, an image of a larger patch of the retina was obtained by stitching of 9 images acquired with a 4 degrees *4 degrees FoV, resulting in a total FoV of 10 degrees *10 degrees . Finally, different retinal layers were imaged by shifting the focal plane. PMID- 29188084 TI - Lens internal curvature effects on age-related eye model and lens paradox. AB - The gradient index (GRIN) model is the most accurate way to represent the eye lens which, because of its growth mode, is a lamellar, shell-like structure. The GRIN is thought to provide optical properties that counteract age-related changes in curvature that would otherwise create an increasingly myopic eye: the so called lens paradox. This article investigates how fine-tuning the refractive index and the internal curvatures of the lenticular indicial contours may prevent the ageing eye from becoming myopic. A system matrix approach is applied for analysis of a shell model with 200 shells to obtain the paraxial characteristics of the eye model. PMID- 29188085 TI - Novel health monitoring method using an RGB camera. AB - In this paper we present a novel health monitoring method by estimating the heart rate and respiratory rate using an RGB camera. The heart rate and the respiratory rate are estimated from the photoplethysmography (PPG) and the respiratory motion. The method mainly operates by using the green spectrum of the RGB camera to generate a multivariate PPG signal to perform multivariate de-noising on the video signal to extract the resultant PPG signal. A periodicity based voting scheme (PVS) was used to measure the heart rate and respiratory rate from the estimated PPG signal. We evaluated our proposed method with a state of the art heart rate measuring method for two scenarios using the MAHNOB-HCI database and a self collected naturalistic environment database. The methods were furthermore evaluated for various scenarios at naturalistic environments such as a motion variance session and a skin tone variance session. Our proposed method operated robustly during the experiments and outperformed the state of the art heart rate measuring methods by compensating the effects of the naturalistic environment. PMID- 29188086 TI - In vivo study of optical speckle decorrelation time across depths in the mouse brain. AB - The strong optical scattering of biological tissue confounds our ability to focus light deeply into the brain beyond depths of a few hundred microns. This challenge can be potentially overcome by exploiting wavefront shaping techniques which allow light to be focused through or inside scattering media. However, these techniques require the scattering medium to be static, as changes in the arrangement of the scatterers between the wavefront recording and playback steps reduce the fidelity of the focus that is formed. Furthermore, as the thickness of the scattering medium increases, the influence of the dynamic nature becomes more severe due to the growing number of scattering events experienced by each photon. In this paper, by examining the scattering dynamics in the mouse brain in vivo via multispeckle diffusing wave spectroscopy (MSDWS) using a custom fiber probe that simulates a point-like source within the brain, we investigate the relationship between this decorrelation time and the depth of the point-like light source inside the living mouse brain at depths up to 3.2 mm. PMID- 29188087 TI - Elemental analysis of the thyroid by laser induced breakdown spectroscopy. AB - The thyroid is an important hormone regulation organ. Laser induced breakdown spectroscopy (LIBS) is developed to assess iodine and other essential elements in the thyroid (of rats). Subjects are administered 0.05% iodine water for 0, 6, and 12 days before the thyroid is extracted. Pronounced iodine, sodium, calcium, and potassium emissions are observed at approximately 746, 589, 395/422, and 766/770 nm, respectively. Iodine emission is surprisingly highest in 0 day subjects, lowest after 6 days, and recovers by 12 days. This follows the Wolff-Chaikoff effect as ingestion of excess iodine reduces thyroid iodine and iodine is essential for hormone production. LIBS is a promising method for trace elemental analysis of the thyroid. PMID- 29188088 TI - Virtually increased acceptance angle for efficient estimation of spatially resolved reflectance in the subdiffusive regime: a Monte Carlo study. AB - Light propagation in biological tissues is frequently modeled by the Monte Carlo (MC) method, which requires processing of many photon packets to obtain adequate quality of the observed backscattered signal. The computation times further increase for detection schemes with small acceptance angles and hence small fraction of the collected backscattered photon packets. In this paper, we investigate the use of a virtually increased acceptance angle for efficient MC simulation of spatially resolved reflectance and estimation of optical properties by an inverse model. We devise a robust criterion for approximation of the maximum virtual acceptance angle and evaluate the proposed methodology for a wide range of tissue-like optical properties and various source configurations. PMID- 29188089 TI - Improving lateral resolution and image quality of optical coherence tomography by the multi-frame superresolution technique for 3D tissue imaging. AB - The multi-frame superresolution technique is introduced to significantly improve the lateral resolution and image quality of spectral domain optical coherence tomography (SD-OCT). Using several sets of low resolution C-scan 3D images with lateral sub-spot-spacing shifts on different sets, the multi-frame superresolution processing of these sets at each depth layer reconstructs a higher resolution and quality lateral image. Layer by layer processing yields an overall high lateral resolution and quality 3D image. In theory, the superresolution processing including deconvolution can solve the diffraction limit, lateral scan density and background noise problems together. In experiment, the improved lateral resolution by ~3 times reaching 7.81 um and 2.19 um using sample arm optics of 0.015 and 0.05 numerical aperture respectively as well as doubling the image quality has been confirmed by imaging a known resolution test target. Improved lateral resolution on in vitro skin C-scan images has been demonstrated. For in vivo 3D SD-OCT imaging of human skin, fingerprint and retina layer, we used the multi-modal volume registration method to effectively estimate the lateral image shifts among different C-scans due to random minor unintended live body motion. Further processing of these images generated high lateral resolution 3D images as well as high quality B-scan images of these in vivo tissues.

AB - [This corrects the article on p. 1430 in vol. 8, PMID: 28663839.]. PMID- 29188091 TI - Compact fs ytterbium fiber laser at 1010 nm for biomedical applications. AB - Ytterbium-doped fiber lasers (YDFLs) working in the near-infrared (NIR) spectral window and capable of high-power operation are popular in recent years. They have been broadly used in a variety of scientific and industrial research areas, including light bullet generation, optical frequency comb formation, materials fabrication, free-space laser communication, and biomedical diagnostics as well. The growing interest in YDFLs has also been cultivated for the generation of high power femtosecond (fs) pulses. Unfortunately, the operating wavelengths of fs YDFLs have mostly been confined to two spectral bands, i.e., 970-980 nm through the three-level energy transition and 1030-1100 nm through the quasi three-level energy transition, leading to a spectral gap (990-1020 nm) in between, which is attributed to an intrinsically weak gain in this wavelength range. Here we demonstrate a high-power mode-locked fs YDFL operating at 1010 nm, which is accomplished in a compact and cost-effective package. It exhibits superior performance in terms of both short-term and long-term stability, i.e., <0.3% (peak intensity over 2.4 MUs) and <4.0% (average power over 24 hours), respectively. To illustrate the practical applications, it is subsequently employed as a versatile fs laser for high-quality nonlinear imaging of biological samples, including two-photon excited fluorescence microscopy of mouse kidney and brain sections, as well as polarization-sensitive second-harmonic generation microscopy of potato starch granules and mouse tail muscle. It is anticipated that these efforts will largely extend the capability of fs YDFLs which is continuously tunable over 970-1100 nm wavelength range for wideband hyperspectral operations, serving as a promising complement to the gold-standard Ti:sapphire fs lasers. PMID- 29188092 TI - Real time complete Stokes polarimetric imager based on a linear polarizer array camera for tissue polarimetric imaging. AB - Tissue polarimetric imaging measures Mueller matrices of tissues or Stokes vectors of the emergent light from tissues (normally using incidence with a fixed polarization state) over a field of view, and has demonstrated utility in a number of surgical and diagnostic applications. Here we introduce a compact complete Stokes polarimetric imager that can work for multiple wavelength bands with a frame-rate suitable for real-time applications. The imager was validated with standard polarizing components, and then employed as a polarization state analyzer of a Mueller imaging polarimeter and a standalone Stokes imaging polarimeter respectively to image the process of dehydration of bovine tendon tissue. The results obtained in this work suggested that the polarization properties of the samples rich of collagen fibres can change with the degree of dehydration, and therefore, dehydration of the samples prepared for polarimetric imaging (e.g. polarimetric microscopy) should be carefully controlled. PMID- 29188093 TI - Fully automated laser ray tracing system to measure changes in the crystalline lens GRIN profile. AB - Measuring the lens gradient refractive index (GRIN) accurately and reliably has proven an extremely challenging technical problem. A fully automated laser ray tracing (LRT) system was built to address this issue. The LRT system captures images of multiple laser projections before and after traversing through an ex vivo lens. These LRT images, combined with accurate measurements of the lens geometry, are used to calculate the lens GRIN profile. Mathematically, this is an ill-conditioned problem; hence, it is essential to apply biologically relevant constraints to produce a feasible solution. The lens GRIN measurements were compared with previously published data. Our GRIN retrieval algorithm produces fast and accurate measurements of the lens GRIN profile. Experiments to study the optics of physiologically perturbed lenses are the future direction of this research. PMID- 29188094 TI - Molecular response of mitochondria to a short-duration femtosecond-laser stimulation. AB - The research of mitochondrial dysfunction is of great importance and implicated in a range of neurodegenerative diseases. Traditionally, to investigate mitochondrial dynamics and functions, mitochondria are usually stimulated indirectly by treating cells with exogenous chemicals like oxidative agents. Such treatment lacks precision and controllability, and will simultaneously activate unknown complex cell processes. In this study, we report that two-photon 100-MUs line scan by a femtosecond laser can induce restorable fragmentation or swelling of any targeted mitochondria instead of ablation or disruption. It can be defined by a customized two-photon line scan and inserted into any microscopy sequence as a single frame. The mitochondrial response is dependent on the peak power of laser pulses, cellular oxidative environment, and membrane permeability transition pores of mitochondria. The translocation of cytochrome C and Bax can be regulated by the photostimulation. Moreover, significant upregulation of Bcl-2 can be observed if the whole cell is stimulated. Those results suggest the mitochondrial and molecular response to photostimulation is quite complex. This femtosecond-laser stimulation method can thus provide a very noninvasive, precise, and controllable method to stimulate single target mitochondria for related biological research. PMID- 29188095 TI - Comparison of four methods of surface roughness assessment of corneal stromal bed after lamellar cutting. AB - Corneal lamellar cutting with a blade or femtosecond laser (FSL) is commonly used during refractive surgery and corneal grafts. Surface roughness of the cutting plane influences postoperative visual acuity but is difficult to assess reliably. For the first time, we compared chromatic confocal microscopy (CCM) with scanning electron microscopy, atomic force microscopy (AFM) and focus-variation microscopy (FVM) to characterize surfaces of variable roughness after FSL cutting. The small area allowed by AFM hinders conclusive roughness analysis, especially with irregular cuts. FVM does not always differentiate between smooth and rough surfaces. Finally, CCM allows analysis of large surfaces and differentiates between surface states. PMID- 29188096 TI - Cerebral time domain-NIRS: reproducibility analysis, optical properties, hemoglobin species and tissue oxygen saturation in a cohort of adult subjects. AB - The reproducibility of cerebral time-domain near-infrared spectroscopy (TD-NIRS) has not been investigated so far. Besides, reference intervals of cerebral optical properties, of absolute concentrations of deoxygenated-hemoglobin (HbR), oxygenated-hemoglobin (HbO), total hemoglobin (HbT) and tissue oxygen saturation (StO2) and their variability have not been reported. We have addressed these issues on a sample of 88 adult healthy subjects. TD-NIRS measurements at 690, 785, 830 nm were fitted with the diffusion model for semi-infinite homogenous media. Reproducibility, performed on 3 measurements at 5 minutes intervals, ranges from 1.8 to 6.9% for each of the hemoglobin species. The mean +/- SD global values of HbR, HbO, HbT, StO2 are respectively 24 +/- 7 MUM, 33.3 +/- 9.5 MUM, 57.4 +/- 15.8 MUM, 58 +/- 4.2%. StO2 displays the narrowest range of variability across brain regions. PMID- 29188098 TI - Active thermodynamic contrast imaging for label-free tumor detection in a murine xenograft tumor model. AB - Passive thermal imaging provides a limited differentiation between a tumor and neighboring tissue based on the temperature difference. We propose active thermodynamic contrast imaging (ATCI) with convection thermal modulators to provide more physiologically relevant parameters with high contrast such as the rate of temperature change, and thermal recovery time for tumor detection with a murine xenograft tumor model. With early stage tumors, we found the average rate of temperature change was higher in the tumor (0.22 +/- 0.06 [Formula: see text]/sec) than that of neighboring tissue (0.13 +/- 0.01 [Formula: see text]/sec) with heating modulation. With established tumors (volume > 100 mm3), this tendency was greater. On the other hand, the thermal recovery time was shorter in tumor tissue (tau = 7.30 +/- 0.59 sec) than that of neighboring tissue (tau = 11.91 +/- 2.22 sec). We also found distinct thermal contrast with cooling modulation. These data suggest ATCI is a potential tumor detection modality for clinical application with its inherently label-free and physiology-based approach. Furthermore, this strategy may find applications in endoscopic tumor detection in the future. PMID- 29188097 TI - Noninvasive structural and microvascular anatomy of oral mucosae using handheld optical coherence tomography. AB - In this study, we demonstrated the feasibility of using a handheld optical coherence tomography (OCT) for in vivo visualizations of the microstructural and microvascular features of various oral mucosal types. To scan arbitrary locations of the oral mucosa, a scanning probe was developed, composed of a probe body fabricated by a 3D printer, miniaturized two-axis galvanometer, relay lenses, and reflective prism. With a 3D printing technique, the probe weight and the system volume were greatly reduced, enabling the effective improvement of imaging artifacts from unconscious motion and system complexity. Additionally, in our design, the distal end of the probe can be switched to fit various oral conditions, and the optical parameters of the probe, such as the transverse resolution, working distance, and probe length can be easily varied. The results showed that the epithelium and lamina propria layers, as well as the fungiform papilla and salivary gland, were differentiated. Moreover, various microcirculation features at different mucosal sites were identified that are potentially effective indicators for the diagnosis of premalignant lesions. The demonstrated results indicate that the developed OCT system is a promising tool for noninvasive imaging of oral mucosae. PMID- 29188099 TI - Serial optical coherence scanning reveals an association between cardiac function and the heart architecture in the aging rodent heart. AB - Normal aging is accompanied by structural changes in the heart architecture. To explore this remodeling, we used a serial optical coherence tomography scanner to image entire mouse hearts at micron scale resolution. Ex vivo hearts of 7 young (4 months) and 5 old (24 months) C57BL/6 mice were acquired with the imaging platform. OCT of the myocardium revealed myofiber orientation changing linearly from the endocardium to the epicardium. In old mice, this rate of change was lower when compared to young mice while the average volume of old mice hearts was significantly larger (p<0.05). Myocardial wall thickening was also accompanied by extracellular spacing in the endocardium, resulting in a lower OCT attenuation coefficient in old mice endocardium (p<0.05). Prior to serial sectioning, cardiac function of the same hearts was imaged in vivo using MRI and revealed a reduced ejection fraction with aging. The use of a serial optical coherence tomography scanner allows new insight into fine age-related changes of the heart associated with changes in heart function.

PMID- 29188101 TI - Photodynamic opening of blood-brain barrier. AB - Photodynamic treatment (PDT) causes a significant increase in the permeability of the blood-brain barrier (BBB) in healthy mice. Using different doses of laser radiation (635 nm, 10-40 J/cm2) and photosensitizer (5-aminolevulinic acid - 5 ALA, 20 and 80 mg/kg, i.v.), we found that the optimal PDT for the reversible opening of the BBB is 15 J/cm2 and 5-ALA, 20 mg/kg, exhibiting brain tissues recovery 3 days after PDT. Further increases in the laser radiation or 5-ALA doses have no amplifying effect on the BBB permeability, but are associated with severe damage of brain tissues. These results can be an informative platform for further studies of new strategies in brain drug delivery and for better understanding of mechanisms underlying cerebrovascular effects of PDT-related fluorescence guided resection of brain tumor. PMID- 29188102 TI - Automated drusen detection in dry age-related macular degeneration by multiple depth, en face optical coherence tomography. AB - We introduce a method to automatically detect drusen in dry age-related macular degeneration (AMD) from optical coherence tomography with minimum need for layer segmentation. The method is based on the en face detection of drusen areas in C scans at certain distances above the Bruch's membrane, circumventing the difficult task of pathologic retinal pigment epithelium segmentation. All types of drusen can be detected, including the challenging subretinal drusenoid deposits (pseudodrusen). The high sensitivity and accuracy demonstrated here shows its potential for detection of drusen onset in early AMD. PMID- 29188103 TI - Comparison of second harmonic microscopy images of collagen-based ocular tissues with 800 and 1045 nm. AB - Second harmonic generation (SHG) imaging is a well-suited multiphoton technique allowing visualization of biological tissues mainly composed of collagen with submicron resolution. Despite its inherent confocal properties, imaging of deeper layers within thick samples has still some limitations. Although the use of longer wavelengths might help to overcome this, the dependence between SHG signals and wavelength is still under discussion. We report here on the dependence with wavelength of SHG signals from collagen-based ocular tissues. The quality of SHG images for two commonly used excitation wavelengths (800 and 1045 nm) is studied. The analysis of the collagen structural information reveals that the information provided by both wavelengths is similar. It was also found that, independently of the depth location, 1045-nm SHG images presented always lower signal levels than those acquired with 800 nm. However, the contrast of the former images was higher, what may improve the visualization of certain features of interest. PMID- 29188104 TI - Open-source do-it-yourself multi-color fluorescence smartphone microscopy. AB - Fluorescence microscopy is an important technique for cellular and microbiological investigations. Translating this technique onto a smartphone can enable particularly powerful applications such as on-site analysis, on-demand monitoring, and point-of-care diagnostics. Current fluorescence smartphone microscope setups require precise illumination and imaging alignment which altogether limit its broad adoption. We report a multi-color fluorescence smartphone microscope with a single contact lens-like add-on lens and slide launched total-internal-reflection guided illumination for three common tasks in investigative fluorescence microscopy: autofluorescence, fluorescent stains, and immunofluorescence. The open-source, simple and cost-effective design has the potential for do-it-yourself fluorescence smartphone microscopy. PMID- 29188105 TI - Adaptive optics stochastic optical reconstruction microscopy (AO-STORM) by particle swarm optimization. AB - Stochastic optical reconstruction microscopy (STORM) can achieve resolutions of better than 20nm imaging single fluorescently labeled cells. However, when optical aberrations induced by larger biological samples degrade the point spread function (PSF), the localization accuracy and number of localizations are both reduced, destroying the resolution of STORM. Adaptive optics (AO) can be used to correct the wavefront, restoring the high resolution of STORM. A challenge for AO STORM microscopy is the development of robust optimization algorithms which can efficiently correct the wavefront from stochastic raw STORM images. Here we present the implementation of a particle swarm optimization (PSO) approach with a Fourier metric for real-time correction of wavefront aberrations during STORM acquisition. We apply our approach to imaging boutons 100 MUm deep inside the central nervous system (CNS) of Drosophila melanogaster larvae achieving a resolution of 146 nm. PMID- 29188106 TI - Non-invasive assessment of human cone photoreceptor function. AB - Vision begins when light isomerizes the photopigments within photoreceptors. Noninvasive cellular-scale observation of the structure of the human photoreceptor mosaic is made possible through the use of adaptive optics (AO) enhanced ophthalmoscopes, but establishing noninvasive objective measures of photoreceptor function on a similar scale has been more difficult. AO ophthalmoscope images acquired with near-infrared light show that individual cone photoreceptor reflectance can change in response to a visible stimulus. Here we show that the intrinsic response depends on stimulus wavelength and intensity, and that its action spectrum is well-matched to the spectral sensitivity of cone mediated vision. Our results demonstrate that the cone reflectance response is mediated by photoisomerization, thus making it a direct measure of photoreceptor function. PMID- 29188107 TI - Real-time endoscopic optical properties imaging. AB - With almost 50% of all surgeries in the U.S. being performed as minimally invasive procedures, there is a need to develop quantitative endoscopic imaging techniques to aid surgical guidance. Recent developments in widefield optical imaging make endoscopic implementations of real-time measurement possible. In this work, we introduce a proof-of-concept endoscopic implementation of a functional widefield imaging technique called 3D single snapshot of optical properties (3D-SSOP) that provides quantitative maps of absorption and reduced scattering optical properties as well as surface topography with simple instrumentation added to a commercial endoscope. The system's precision and accuracy is validated using tissue-mimicking phantoms, showing a max error of 0.004 mm-1, 0.05 mm-1, and 1.1 mm for absorption, reduced scattering, and sample topography, respectively. This study further demonstrates video acquisition of a moving phantom and an in vivo sample with a framerate of approximately 11 frames per second. PMID- 29188108 TI - Ultrahigh-resolution optical coherence elastography through a micro-endoscope: towards in vivo imaging of cellular-scale mechanics. AB - In this paper, we describe a technique capable of visualizing mechanical properties at the cellular scale deep in living tissue, by incorporating a gradient-index (GRIN)-lens micro-endoscope into an ultrahigh-resolution optical coherence elastography system. The optical system, after the endoscope, has a lateral resolution of 1.6 um and an axial resolution of 2.2 um. Bessel beam illumination and Gaussian mode detection are used to provide an extended depth-of field of 80 um, which is a 4-fold improvement over a fully Gaussian beam case with the same lateral resolution. Using this system, we demonstrate quantitative elasticity imaging of a soft silicone phantom containing a stiff inclusion and a freshly excised malignant murine pancreatic tumor. We also demonstrate qualitative strain imaging below the tissue surface on in situ murine muscle. The approach we introduce here can provide high-quality extended-focus images through a micro-endoscope with potential to measure cellular-scale mechanics deep in tissue. We believe this tool is promising for studying biological processes and disease progression in vivo. PMID- 29188109 TI - Speckle variance OCT for depth resolved assessment of the viability of bovine embryos. AB - The morphology of embryos produced by in vitro fertilization (IVF) is commonly used to estimate their viability. However, imaging by standard microscopy is subjective and unable to assess the embryo on a cellular scale after compaction. Optical coherence tomography is an imaging technique that can produce a depth resolved profile of a sample and can be coupled with speckle variance (SV) to detect motion on a micron scale. In this study, day 7 post-IVF bovine embryos were observed either short-term (10 minutes) or long-term (over 18 hours) and analyzed by swept source OCT and SV to resolve their depth profile and characterize micron-scale movements potentially associated with viability. The percentage of en face images showing movement at any given time was calculated as a method to detect the vital status of the embryo. This method could be used to measure the levels of damage sustained by an embryo, for example after cryopreservation, in a rapid and non-invasive way. PMID- 29188110 TI - Optimal hemoglobin extinction coefficient data set for near-infrared spectroscopy. AB - Extinction coefficient (epsilon) is a critical parameter for quantification of oxy-, deoxy-, and total-hemoglobin concentrations (Delta[HbO2], Delta[Hb], Delta[tHb]) from optical measurements of Near-infrared spectroscopy (NIRS). There are several different epsilon data sets which were frequently used in NIRS quantification. A previous study reported that even a small variation in epsilon could cause a significant difference in hemodynamic measurements. Apparently the selection of an optimal epsilon data set is important for NIRS. We conducted oxygen-state-varied and blood-concentration-varied model experiments with 57 human blood samples to mimic tissue hemodynamic variations. Seven reported epsilon data sets were evaluated by comparisons between quantifications and assumed values. We found that the Moaveni et al (1970)' epsilon data set was the optimal one, the NIRS quantification varied significantly among different epsilon data sets and parameter Delta[tHb] was most sensitive to epsilon data sets selection. PMID- 29188111 TI - Automatic detection of the foveal center in optical coherence tomography. AB - We propose a method for automatic detection of the foveal center in optical coherence tomography (OCT). The method is based on a pixel-wise classification of all pixels in an OCT volume using a fully convolutional neural network (CNN) with dilated convolution filters. The CNN-architecture contains anisotropic dilated filters and a shortcut connection and has been trained using a dynamic training procedure where the network identifies its own relevant training samples. The performance of the proposed method is evaluated on a data set of 400 OCT scans of patients affected by age-related macular degeneration (AMD) at different severity levels. For 391 scans (97.75%) the method identified the foveal center with a distance to a human reference less than 750 MUm, with a mean (+/- SD) distance of 71 MUm +/- 107 MUm. Two independent observers also annotated the foveal center, with a mean distance to the reference of 57 MUm +/- 84 MUm and 56 MUm +/- 80 MUm, respectively. Furthermore, we evaluate variations to the proposed network architecture and training procedure, providing insight in the characteristics that led to the demonstrated performance of the proposed method. PMID- 29188112 TI - Multimode fibre based imaging for optically cleared samples. AB - Optical clearing is emerging as a popular approach particularly for studies in neuroscience. However the use of corrosive clearing solutions typically requires sophisticated objectives or extreme care with optical components chosen for single- or multi-photon imaging. In contrast to the use of complex, custom-made microscope objectives, we show that the use of a corrected multimode fibre (MMF) offers a route that is resistant to corrosion, can be used in clearing media, is not constrained by the refractive index of the immersion medium and offers flexible working distances. Using a corrected MMF, we demonstrate fluorescence imaging of beads and stained neuroblastoma cells through optically cleared mouse brain tissue, as well as imaging in an extreme oxidative environment to show the versatility of our approach. Additionally, we perform Raman imaging of polystyrene beads in clearing media to demonstrate that this approach may be used for vibrational spectroscopy of optically cleared samples. PMID- 29188113 TI - Label-free fiber optic optrode for the detection of class C beta-lactamases expressed by drug resistant bacteria. AB - This paper reports the experimental assessment of an automated optical assay based on label free optical fiber optrodes for the fast detection of class C beta lactamases (AmpC BLs), actually considered as one of the most important sources of resistance to beta-lactams antibiotics expressed by resistant bacteria. Reflection-type long period fiber gratings (RT-LPG) have been used as highly sensitive label free optrodes, while a higher affine boronic acid-based ligand was here selected to enhance the overall assay performances compared to those obtained in our first demonstration. In order to prove the feasibility analysis towards a fully automated optical assay, an engineered system was developed to simultaneously manipulate and interrogate multiple fiber optic optrodes in the different phases of the assay. The automated system tested in AmpC solutions at increasing concentrations demonstrated a limit of detection (LOD) of 6 nM, three times better when compared with the results obtained in our previous work. Moreover, the real effectiveness of the proposed optical assay has been also confirmed in complex matrices as the case of lysates of Escherichia coli overexpressing AmpC. PMID- 29188114 TI - Optical surface plasmon resonance sensor modified by mutant glucose/galactose binding protein for affinity detection of glucose molecules. AB - Transdermal extraction of interstitial fluid (ISF) offers an attractive method for minimally invasive blood glucose monitoring. However, only a minute volume of ISF could be transdermally extracted, which is required to be diluted to form a manipulable volume of fluid for easy collection, transportation, and glucose detection. Therefore, a high-resolution glucose detection method is required for detecting glucose concentration in diluted ISF. In this paper, an optical surface plasmon resonance (SPR) sensor modified by the glucose/galactose-binding (GGB) protein which has good affinity to glucose molecules was presented for specific and sensitive glucose detection. The GGB protein was mutated at different sites for thiol coupling with the SPR surface and adjusting the affinity between glucose molecules and GGB protein. And the immobilization process of the GGB protein onto the surface of SPR sensor was optimized. Then, the stability of the SPR sensor modified with GGB protein was tested immediately and two weeks after immobilization. The coefficient of variation for glucose concentration measurement was less than 4.5%. By further mutation of the GGB protein at the A213S and L238S sites, the measurement range of the SPR sensor was adjusted to 0.1-100 mg/dL, which matches the glucose concentration range of 5-10 times diluted ISF (3-100 mg/dL). These results suggest that the SPR biosensor immobilized with GGB protein has the potential for continuous glucose monitoring by integrating into the microfluidic ISF extraction chip. PMID- 29188115 TI - Raman spectral post-processing for oral tissue discrimination - a step for an automatized diagnostic system. AB - Most oral injuries are diagnosed by histopathological analysis of a biopsy, which is an invasive procedure and does not give immediate results. On the other hand, Raman spectroscopy is a real time and minimally invasive analytical tool with potential for the diagnosis of diseases. The potential for diagnostics can be improved by data post-processing. Hence, this study aims to evaluate the performance of preprocessing steps and multivariate analysis methods for the classification of normal tissues and pathological oral lesion spectra. A total of 80 spectra acquired from normal and abnormal tissues using optical fiber Raman based spectroscopy (OFRS) were subjected to PCA preprocessing in the z-scored data set, and the KNN (K-nearest neighbors), J48 (unpruned C4.5 decision tree), RBF (radial basis function), RF (random forest), and MLP (multilayer perceptron) classifiers at WEKA software (Waikato environment for knowledge analysis), after area normalization or maximum intensity normalization. Our results suggest the best classification was achieved by using maximum intensity normalization followed by MLP. Based on these results, software for automated analysis can be generated and validated using larger data sets. This would aid quick comprehension of spectroscopic data and easy diagnosis by medical practitioners in clinical settings. PMID- 29188117 TI - Efficiency enhancement of Raman spectroscopy at long working distance by parabolic reflector. AB - Raman spectroscopy is well suited for readily revealing information about bio samples. As such, this technique has been applied to a wide range of areas, particularly in bio-medical diagnostics. Raman scattering in bio-samples typically has a low signal level due to the nature of inelastic scattering of photons. To achieve a high signal level, usually a high numerical aperture objective is employed. One drawback with these objectives is that their working distance is very short. However, in many cases of clinical diagnostics, a long working distance is preferable. We propose a practical solution to this problem by enhancing the Raman signal using a parabolic reflector. The high signal level is achieved through the large light collection solid angle of the parabolic reflector while the long working distance is ensured by the novel design of our microscope. The enhancement capability of the microscope was demonstrated on four types of samples. Among these samples, we find that this microscope design is most suitable for turbid samples. PMID- 29188116 TI - Multimodal nonlinear optical imaging of unstained retinas in the epi-direction with a sub-40 fs Yb-fiber laser. AB - Ultrafast lasers have potential use in ophthalmology for diagnoses through non invasive imaging as well as for surgical therapies or for evaluating pharmacological therapies. New ultrafast laser sources, operating at 1.07 MUm and sub-40 fs pulse durations, offer exciting possibilities in multiphoton imagining of the retina as the bulk of the eye is relatively transparent to this wavelength, three-photon excitation is not absorbed by DNA, and this wavelength has a greater penetration depth compared to the commonly used 800 nm Ti:Sapphire laser. In this work, we present the first epi-direction detected cross-section and depth-resolved images of unstained isolated retinas obtained using multiphoton microscopy with an ultrafast fiber laser centered at 1.07 MUm and a ~38 fs pulse duration. Spectral and temporal characterization of the autofluorescence signals show two distinct regions; the first one from the nerve fiber layer to the inner receptor layer, and the second being the retinal pigmented epithelium and choroid. PMID- 29188118 TI - Common-path phase-sensitive optical coherence tomography provides enhanced phase stability and detection sensitivity for dynamic elastography. AB - Phase-sensitive optical coherence elastography (PhS-OCE) is an emerging optical technique to quantify soft-tissue biomechanical properties. We implemented a common-path OCT design to enhance displacement sensitivity and optical phase stability for dynamic elastography imaging. The background phase stability was greater in common-path PhS-OCE (0.24 +/- 0.07nm) than conventional PhS-OCE (1.60 +/- 0.11MUm). The coefficient of variation for surface displacement measurements using conventional PhS-OCE averaged 11% versus 2% for common-path PhS-OCE. Young's modulus estimates showed good precision (95% CIs) for tissue phantoms: 24.96 +/- 2.18kPa (1% agar), 49.69 +/- 4.87kPa (1.5% agar), and 116.08 +/- 12.14kPa (2% agar), respectively. Common-path PhS-OCE effectively reduced the amplitude of background dynamic optical phase instability to a sub-nanometer level, which provided a larger dynamic detection range and higher detection sensitivity for surface displacement measurements than conventional PhS-OCE. PMID- 29188119 TI - Multi-shaping technique reduces sidelobe magnitude in optical coherence tomography. AB - Shaping methods that are commonly used in Fourier-domain optical coherence tomography (FD-OCT) can suppress sidelobe artifacts in the axial direction, but they typically broaden the mainlobe of the point spread function (PSF) and reduce the axial resolution. To improve OCT image quality without this tradeoff, we have developed a multi-shaping technique that reduces the axial sidelobe magnitude dramatically and achieves better axial resolution than conventional shaping methods. This technique is robust and compatible in various FD-OCT imaging systems. Testing of multi-shaping in three experimental settings shows that it reduced the axial sidelobe contribution by more than 8 dB and improved the contrast to noise by at least 30% and up to three-fold. Multi-shaping enables accurate image analysis and is potentially useful in many OCT applications. PMID- 29188120 TI - Data-driven imaging of tissue inflammation using RGB-based hyperspectral reconstruction toward personal monitoring of dermatologic health. AB - Sensitive and accurate assessment of dermatologic inflammatory hyperemia in otherwise grossly normal-appearing skin conditions is beneficial to laypeople for monitoring their own skin health on a regular basis, to patients for looking for timely clinical examination, and to primary care physicians or dermatologists for delivering effective treatments. We propose that mathematical hyperspectral reconstruction from RGB images in a simple imaging setup can provide reliable visualization of hemoglobin content in a large skin area. Without relying on a complicated, expensive, and slow hyperspectral imaging system, we demonstrate the feasibility of determining heterogeneous or multifocal areas of inflammatory hyperemia associated with experimental photocarcinogenesis in mice. We envision that RGB-based reconstructed hyperspectral imaging of subclinical inflammatory hyperemic foci could potentially be integrated with the built-in camera (RGB sensor) of a smartphone to develop a simple imaging device that could offer affordable monitoring of dermatologic health. PMID- 29188121 TI - Statistical independence in nonlinear model-based inversion for quantitative photoacoustic tomography. AB - The statistical independence between the distributions of different chromophores in tissue has previously been used for linear unmixing with independent component analysis (ICA). In this study, we propose exploiting this statistical property in a nonlinear model-based inversion method. The aim is to reduce the sensitivity of the inversion scheme to errors in the modelling of the fluence, and hence provide more accurate quantification of the concentration of independent chromophores. A gradient-based optimisation algorithm is used to minimise the error functional, which includes a term representing the mutual information between the chromophores in addition to the standard least-squares data error. Both numerical simulations and an experimental phantom study are conducted to demonstrate that, in the presence of experimental errors in the fluence model, the proposed inversion method results in more accurate estimation of the concentrations of independent chromophores compared to the standard model-based inversion. PMID- 29188122 TI - Time domain diffuse correlation spectroscopy with a high coherence pulsed source: in vivo and phantom results. AB - Diffuse correlation spectroscopy (DCS), combined with time-resolved reflectance spectroscopy (TRS) or frequency domain spectroscopy, aims at path length (i.e. depth) resolved, non-invasive and simultaneous assessment of tissue composition and blood flow. However, while TRS provides a path length resolved data, the standard DCS does not. Recently, a time domain DCS experiment showed path length resolved measurements for improved quantification with respect to classical DCS, but was limited to phantoms and small animal studies. Here, we demonstrate time domain DCS for in vivo studies on the adult forehead and the arm. We achieve path length resolved DCS by means of an actively mode-locked Ti:Sapphire laser that allows high coherence pulses, thus enabling adequate signal-to-noise ratio in relatively fast (~1 s) temporal resolution. This work paves the way to the translation of this approach to practical in vivo use. PMID- 29188124 TI - Measuring blood oxygen saturation along a capillary vessel in human. AB - Measuring oxygen saturation in capillary vessels could provide valuable information on oxygen transport and tissue viability. Most spectroscopic measurement techniques, however, lack the spatial resolution to account for the small vessel dimensions within a scattering tissue and the steep gradients of oxygen saturation levels. Here, we developed a noninvasive technique for image guided confocal measurement of the optical absorption spectrum from a small region that is comparable in size to the cross section of a single capillary vessel. A wide range of oxygen saturation levels were measured in a single capillary in a human volunteer, with blood deoxygenation rates of 7.1% per hundred microns. The technique could help in studying oxygen exchange dynamics in tissues and could play a key role in future clinical diagnosis and therapeutic applications that require localized functional tissue inspection. PMID- 29188125 TI - Direct inversion algorithm for focal plane scanning optical projection tomography. AB - To achieve approximately parallel projection geometry, traditional optical projection tomography (OPT) requires the use of low numerical aperture (NA) objectives, which have a long depth-of-field at the expense of poor lateral resolution. Particularly promising methods to improve spatial resolution include ad-hoc post-processing filters that limit the effect of the system's MTF and focal-plane-scanning OPT (FPS-OPT), an alternative acquisition procedure that allows the use of higher NA objectives by limiting the effect of their shallow depth of field yet still assumes parallel projection rays during reconstruction. Here, we provide a detailed derivation that establishes the existence of a direct inversion formula for FPS-OPT. Based on this formula, we propose a point spread function-aware algorithm that is similar in form and complexity to traditional filtered backprojection (FBP). With simulations, we demonstrate that our point spread-function aware FBP for FPS-OPT leads to more accurate images than both traditional OPT with deconvolution and FPS-OPT with naive FBP reconstruction. We further illustrate the technique on experimental zebrafish data, which shows that our approach reduces out-of-focus blur compared to a direct FBP reconstruction with FPS-OPT. PMID- 29188123 TI - Dynamics of the human brain network revealed by time-frequency effective connectivity in fNIRS. AB - Functional near infrared spectroscopy (fNIRS) is a promising neuroimaging method for investigating networks of cortical regions over time. We propose a directed effective connectivity method (TPDC) allowing the capture of both time and frequency evolution of the brain's networks using fNIRS data acquired from healthy subjects performing a continuous finger-tapping task. Using this method we show the directed connectivity patterns among cortical motor regions involved in the task and their significant variations in the strength of information flow exchanges. Intra and inter-hemispheric connections during the motor task with their temporal evolution are also provided. Characterisation of the fluctuations in brain connectivity opens up a new way to assess the organisation of the brain to adapt to changing task constraints, or under pathological conditions. PMID- 29188126 TI - The United Nations Material Assistance to Survivors of Cholera in Haiti: Consulting Survivors and Rebuilding Trust. AB - Introduction: In August 2016, the United Nations (U.N.) Secretary General acknowledged the U.N.'s role in the cholera epidemic that has beset Haiti since 2010. Two months later, the Secretary General issued a historic apology to the Haitian people before the U.N. General Assembly, for the organization's insufficient response to the cholera outbreak. These steps are part of the U.N.'s "new approach" to cholera in Haiti, which also includes launching a material assistance package for those most affected by cholera. Methods: This paper draws on the authors' experience and findings from consultations with more than 60,000 victims and communities affected by disasters and violence in a dozen countries. We reviewed the literature on best practices for consultation with and outreach to communities affected by development and transitional justice programming, and reviewed our own findings from previous studies with a view to identifying recommendations for ensuring that the assistance package reflects the views of people affected by cholera. Results: The assistance package program is an opportunity to rebuild the relationship between the victims and the United Nations. This can only be achieved if victims are informed and engaged in the process. This consultation effort is also an opportunity to answer a set of key questions related to the nature, structure, and implementation of the victims' assistance program, but also how the program may be designed to contribute to rebuilding Haitians' confidence in the U.N. as an institution that promotes peace, human rights, and development. Discussion: We recommend that the consultations must be accompanied by an outreach effort that provides clear, accurate information on the assistance program, so that it begins to establish a dialogue between the U.N. and cholera victims. Finally, we conclude by offering a number of concrete next steps that the U.N. can take to kick start the consultation process. PMID- 29188127 TI - Enhancing Ebola Virus Disease Surveillance and Prevention in Counties Without Confirmed Cases in Rural Liberia: Experiences from Sinoe County During the Flare up in Monrovia, April to June, 2016. AB - Introduction: During the flare-ups of Ebola virus disease (EVD) in Liberia, Sinoe County reactivated the multi-sectorial EVD control strategy in order to be ready to respond to the eventual reintroduction of cases. This paper describes the impacts of the interventions implemented in Sinoe County during the last flare-up in Monrovia, from April 1 to June 9, 2016, using the resources provided during the original outbreak that ended a year ago. Methods: We conducted a descriptive study to describe the key interventions implemented in Sinoe County, the capacity available, the implications for the reactivation of the multi-sectoral EVD control strategy, and the results of the same. We also conducted a cross sectional study to analyze the impact of the interventions on the surveillance and on infection prevention and control (IPC). Results: The attrition of the staff trained during the original outbreak was low, and most of the supplies, equipment, and infrastructure from the original outbreak remained available. With an additional USD 1755, improvements were observed in the IPC indicators of triage, which increased from a mean of 60% at the first assessment to 77% (P=0.002). Additionally, personnel/staff training improved from 78% to 89% (P=0.04). The percentage of EVD death alerts per expected deaths investigated increased from 26% to 63% (P<0.0001). Discussion: The low attrition of the trained staff and the availability of most supplies, equipment, and infrastructure made the reactivation of the multi-sectoral EVD control strategy fast and affordable. The improvement of the EVD surveillance was possibly affected by the community engagement activities, awareness and mentoring of the health workers, and improved availability of clinicians in the facilities during the flare-up. The community engagement may contribute to the report of community based events, specifically community deaths. The mentoring of the staff during the supportive supervisions also contributed to improve the IPC indicators. PMID- 29188129 TI - A Rights-based Approach to Information in Humanitarian Assistance. AB - Crisis-affected populations and humanitarian aid providers are both becoming increasingly reliant on information and communications technology (ICTs) for finding and provisioning aid. This is exposing critical, unaddressed gaps in the legal and ethical frameworks that traditionally defined and governed the professional conduct of humanitarian action. The most acute of these gaps is a lack of clarity about what human rights people have regarding information in disaster, and the corresponding obligations incumbent upon governments and aid providers. This need is lent urgency by emerging evidence demonstrating that the use of these technologies in crisis response may be, in some cases, causing harm to the very populations they intend to serve. Preventing and mitigating these harms, while also working to responsibly ensure access to the benefits of information during crises, requires a rights-based framework to guide humanitarian operations. In this brief report, we provide a commentary that accompanies our report, the Signal Code: A Human Rights Approach to Information During Crisis, where we have identified five rights pertaining to the use of information and data during crisis which are grounded in current international human rights and customary law. It is our belief that the continued relevance of the humanitarian project, as it grows increasingly dependent on the use of data and ICTs, urgently requires a discussion of these rights and corresponding obligations. PMID- 29188128 TI - Influenza A Virus Infection Damages Zebrafish Skeletal Muscle and Exacerbates Disease in Zebrafish Modeling Duchenne Muscular Dystrophy. AB - INTRODUCTION: Both genetic and infectious diseases can result in skeletal muscle degeneration, inflammation, pain, and/or weakness. Duchenne muscular dystrophy (DMD) is the most common congenital muscle disease. DMD causes progressive muscle wasting due to mutations in Dystrophin. Influenza A and B viruses are frequently associated with muscle complications, especially in children. Infections activate an immune response and immunosuppressant drugs reduce DMD symptoms. These data suggest that the immune system may contribute to muscle pathology. However, roles of the immune response in DMD and Influenza muscle complications are not well understood. Zebrafish with dmd mutations are a well-characterized model in which to study the molecular and cellular mechanisms of DMD pathology. We recently showed that zebrafish can be infected by human Influenza A virus (IAV). Thus, the zebrafish is a powerful system with which to ask questions about the etiology and mechanisms of muscle damage due to genetic and/or infectious diseases. METHODS: We infected zebrafish with IAV and assayed muscle tissue structure, sarcolemma integrity, cell-extracellular matrix (ECM) attachment, and molecular and cellular markers of inflammation in response to IAV infection alone or in the context of DMD. RESULTS: We find that IAV-infected zebrafish display mild muscle degeneration with sarcolemma damage and compromised ECM adhesion. An innate immune response is elicited in muscle in IAV-infected zebrafish: NFkB signaling is activated, pro-inflammatory cytokine expression is upregulated, and neutrophils localize to sites of muscle damage. IAV-infected dmd mutants display more severe muscle damage than would be expected from an additive effect of dmd mutation and IAV infection, suggesting that muscle damage caused by Dystrophin deficiency and IAV infection is synergistic. DISCUSSION: These data demonstrate the importance of preventing IAV infections in individuals with genetic muscle diseases. Elucidating the mechanisms of immune-mediated muscle damage will not only apply to DMD and IAV, but also to other conditions where the immune system, inflammation, and muscle tissue are known to be affected, such as autoimmune diseases, cancer, and aging. PMID- 29188130 TI - First Wave of the 2016-17 Cholera Outbreak in Hodeidah City, Yemen - ACF Experience and Lessons Learned. AB - Introduction: Although cases were reported only in 2010 and 2011, cholera is probably endemic in Yemen. In the context of a civil war, a cholera outbreak was declared in different parts of the country October 6th, 2016. This paper describes the ACF outbreak response in Hodeidah city from October 28th, 2016 to February 28th, 2017 in order to add knowledge to this large outbreak. Methods: The ACF outbreak response in Hodeidah city included a case management component and prevention measures in the community. In partnership with the Ministry of Public Health and Population of Yemen (MoPHP), the case management component included a Cholera Treatment Center (CTC) implemented in the Al Thoraw hospital, 11 Oral Rehydration Therapy Corners (ORTCs) and an active case finding system. In partnership with other stakeholders, prevention measures in the community, including access to safe water and hygiene promotion, were implemented in the most affected communities of the city. Results: From October 28th, 2016 until February 28th, 2017, ACF provided care to 8,270 Acute Watery Diarrhea (AWD) cases, of which 5,210 (63%) were suspected cholera cases, in the CTC and the 11 ORTCs implemented in Hodeidah city. The attack rate was higher among people living in Al Hali district, with a peak in November 2016. At the CTC, 8% of children under 5 years-old also presented with Severe Acute Malnutrition (SAM). The Case-Fatality Rate (CFR) was low (0.07%) but 15% of admitted cases defaulted for cultural and security reasons. Environmental management lacked the information to appropriately target affected areas. Financial resources did not allow complete coverage of the city. Conclusion: Response to the first wave of a large cholera outbreak in Hodeidah city was successful in maintaining a CFR <1% in the CTC. However, considering the actual context of Yemen and its water infrastructure, much more efforts are needed to control the current outbreak resurgence. PMID- 29188131 TI - An Outbreak of Pseudomonas Aeruginosa Infection Linked to a "Black Friday" Piercing Event. AB - Introduction: Outbreaks linked to cosmetic piercing are rare, but can cause significant illness. We report the investigation and management of a point-source outbreak that occurred during a Black Friday promotional event in North West England. Methods: Outbreak investigation was led by Public Health England, and included active case finding among individuals pierced at a piercing premises between 25/11/2016 (Black Friday) and 7/12/2016. Detailed epidemiological, environmental (including inspection and sampling), and microbiological investigation was undertaken. Results: During the Black Friday event (25/11/2016), 45 people were pierced (13 by a newly-appointed practitioner). Eleven cases were identified (7 microbiologically-confirmed, 2 probable, and 2 possible). All cases had clinical signs of infection around piercing sites, and five required surgical intervention, with varying degrees of post-operative disfigurement. All confirmed and probable cases had a scaffold piercing placed with a guide bar by the newly-appointed practitioner. Pseudomonas aeruginosa, indistinguishable at nine-locus variable-number tandem repeat loci, was isolated from four of the confirmed cases, and from pre- and post-flush samples from five separate water taps (three sinks) in the premises. Water samples taken after remedial plumbing work confirmed elimination of Pseudomonas contamination. Discussion: Although high levels of Pseudomonas water contamination and some poor infection control procedures were identified, infection appeared to require additional exposure to an inexperienced practitioner, and the more invasive scaffold piercing. A proactive collaborative approach between piercers and health and environmental officials is required to reduce outbreak risk, particularly when unusually large events are planned. PMID- 29188132 TI - What Do We Mean by 'Community Resilience'? A Systematic Literature Review of How It Is Defined in the Literature. AB - Background: Government, industry and charitable organisations have an increasing focus on programs intended to support community resilience to disasters. But has consensus been reached as to what defines 'community resilience' and what its core characteristics are? Methods: We undertook a systematic literature review of definitions of community resilience related to disasters. We conducted an inductive thematic analysis of the definitions and descriptions that we identified, in order to determine the proposed characteristics of community resilience prior to, during and after a disaster. Results: We identified 80 relevant papers. There was no evidence of a common, agreed definition of community resilience. In spite of this, evidence was found of nine core elements of community resilience that were common among the definitions. The core elements were: local knowledge, community networks and relationships, communication, health, governance and leadership, resources, economic investment, preparedness, and mental outlook. Within these core elements, we identified 19 sub-elements linked to community resilience. Conclusion: Our findings show that community resilience remains an amorphous concept that is understood and applied differently by different research groups. Yet in spite of the differences in conception and application, there are well-understood elements that are widely proposed as important for a resilient community. A focus on these individual elements may be more productive than attempting to define and study community resilience as a distinct concept. PMID- 29188133 TI - Discussion Informed by Recurrent Lessons from a Systematic Review on Targeting Practices in Urban Humanitarian Crises. AB - Introduction: Urbanization has challenged many humanitarian practices given the complexity of cities. Urban humanitarian crises have similarly made identifying vulnerable populations difficult. As humanitarians respond to cities with chronic deficiencies in basic needs stressed by a crisis, identifying and prioritizing the most in need populations with finite resources is critical. Methods: The full systematic review applied standard systematic review methodology that was described in detail, peer-reviewed, and published before the research was conducted.Results: While the science of humanitarian practice is still developing, a systematic review of targeting vulnerable populations in urban humanitarian crises shed some light on the evidence base to guide policy and practice. This systematic review, referenced and available online, led to further findings that did not meet the pre-defined inclusion and exclusion criteria for evidence set out in the full review but that the authors, in their expert opinion, believe provide valuable insight nonetheless given their recurrence.

AB - Introduction: Although more than one billion people live at risk of neglected tropical diseases (NTDs) in areas of Asia, sub-Saharan Africa, and Latin America, the degree to which they burden countries like the U.S. is unclear. Even though many NTDs such as dengue, leishmaniasis, and Chagas disease are typically not endemic to the U.S., the possibility of their emergence is noteworthy, especially in states like Texas with high levels of poverty, large immigrant populations, geographic proximity to endemic areas, and a climate amenable to the vectors for these diseases. Despite the health threat that emerging NTDs may pose, little is known about the prevalence of risk factors for NTDs in the U.S. Methods: We tested the Community Assessment for Public Health Emergency Response (CASPER) method to assess the prevalence of risk factors for NTDs in Brazos County, Texas.Results: We found relatively low prevalence of risk factors related to travel (5.2% of respondents visited an endemic area in the previous 3 months); however, few respondents reported adherence to mosquito prevention, such as wearing long sleeves and long pants (14.1%, 95% CI: 13.9,14.4) and repellant containing DEET (13.5%, 95% CI: 13.2,13.7). Between 5.4% and 35.8% of respondents had a visible container (e.g., pet water dishes, flower pots, bird baths) that could support mosquito breeding. Discussion: CASPER findings present public health authorities with potential avenues for implementing health education and other interventions aimed at reducing exposure to risk factors for NTDs among Texas residents.

AB - Introduction: In Northern Ghana, a combination of torrential rains coupled with the spilling of the Bagre dam in neighboring Burkina Faso in the past few years has resulted in perennial flooding of communities. This has often led to the National Disaster Management Organization (NADMAO) the main disaster responder agency in Ghana, being called upon to act. However affected communities have never had the opportunity to evaluate the activities of the agency. The aim of this study is therefore to assess the performance of the main responder agency by affected community members to improve on future disaster management. Methods: A mixed qualitative design employing a modified form of the community score card methodology and focus group discussions was conducted in the 4 most affected communities during the last floods of 2012 in the Kasena-Nankana West district of the Upper East Region of Northern Ghana. Community members comprising of chiefs, elders, assembly members, women groups, physically challenged persons, farmers, traders and youth groups formed a group in each of the four communities. Generation and scoring of evaluative indicators was subsequently performed by each group through the facilitation of trained research assistants. Four Focus group discussions (FGDs) were also conducted with the group members in each community to get an in-depth understanding of how the responder agency performed in handling disasters. Results: A total of four community score cards and four focus group discussions were conducted involving 48 community representatives. All four communities identified NADMO as the main responder agency during the last disaster. Indicators such as education/awareness, selection process of beneficiaries, networking/collaboration, timing, quantity of relief items, appropriateness, mode of distribution of relief items, investigation and overall performance of NADMO were generated and scored. The timing of response, quantity and appropriateness of relief items were evaluated as being poor whereas the overall performance of the responder agency was above average. Conclusion: NADMO was identified as the main responder agency during the last disasters with community members identifying education/awareness, selection process of beneficiaries, networking/collaboration, timing of response, quantity of relief items, appropriateness of relief items, mode of distribution of relief items, investigation and overall performance as the main evaluative indicators. The overall performance of NADMO was rated to be satisfactory. Key words: Kasena Nankana West district, NADMO, community score card, Rural Northern Ghana.

AB - Introduction: Duchenne Muscular Dystrophy (DMD) is a debilitating muscle wasting disorder with no cure. Safer supplements and therapies are needed to improve the severity of symptoms, as severe side effects are associated with the only effective treatment, corticosteroids. The amino acid taurine has shown promise in ameliorating dystrophic symptoms in mdx mice, an animal model of DMD, however little work is in 21-28 (d)ay animals, the period of natural peak damage. Methods: This study compares the effect of prenatal taurine supplementation on tibialis anterior (TA) in situ contractile function, histopathological characteristics and the abundance of Ca2+-handling as well as pathologically relevant proteins in non-exercised mdx mice at 28 and 70 d. Results: Supplementation elevated TA taurine content by 25% (p<0.05), ameliorated in situ specific force by 60% (p<0.05) and improved histological characteristics in 28 d mdx mice; however no benefit was seen in 70 d mice, where background pathology was initially stable. Age specific effects in SERCA1, calsequestrin 1 (CSQ1), CSQ2, utrophin and myogenin protein abundances were seen between both 28 and 70 d mdx and mdx taurine-supplemented mice. Discussion: Considering these findings and that taurine is a relatively cost effective, readily accessible and side effect free dietary supplement, we propose further investigation into taurine supplementation during pregnancy in a protective capacity, reminiscent of folate in the prevention of spinal bifida. PMID- 29188138 TI - The Effect of Armed Conflict on the Utilization of Maternal Health Services in Uganda: A Population-based Study. AB - Introduction: Maternal mortality rates can be adversely affected by armed conflict, implying a greater level of vulnerability among women, and is often linked to the lack of or limited access to maternal healthcare during conflict. Previous research in Uganda has shown that armed conflict negatively impacts women's utilization of maternal healthcare services for a multitude of reasons at the individual, health-system and political levels. Methods: This study compared aggregated Demographic and Health Surveys data from 13 districts in Northern Uganda, a conflict-affected region, with data from the rest of the country, for the use of maternal healthcare services for the years 1988, 1995, 2000, 2006 and 2011, using statistical analyses and logistic regression. Specific indicators for maternal healthcare utilization included contraceptive use, antenatal care, skilled assistance at birth and institutional delivery. Results: Use of contraception and institutional deliveries among women in Northern Uganda was significantly lower compared to the rest of the country. However, skilled assistance at birth among women in Northern Uganda was significantly higher. Conclusions: The findings in this study show that armed conflict can have a negative impact on aspects of maternal healthcare such as contraceptive use and institutional deliveries; however, other indicators such as skilled assistance at birth were seen to be better among conflict-affected populations. This reiterates the complex nature of armed conflict and the interplay of different factors such as conflict intensity, existing health systems and services, and humanitarian interventions that could influence maternal healthcare utilization. Key words: Armed conflict, maternal health utilization, Northern Uganda, contraception, skilled assistance at birth, antenatal care, institutional delivery. PMID- 29188139 TI - Adipose Tissue Metabolism and Cancer Progression: Novel Insights from Gut Microbiota? AB - Purpose of Review: Obesity is strongly associated with the development of several types of cancers. This review aims to discuss the recent key mechanisms and actors underlying the link between adipose tissue metabolism and cancer, and the unequivocal common mechanisms connecting gut microbes to adipose tissue and eventually cancer development. Recent Findings: Complex interactions among systemic and tissue-specific pathways are suggested to link obesity and cancer, involving endocrine hormones, adipokines, fatty acids, inflammation, metabolic alterations, and hypoxia. Emerging evidence also suggests that the gut microbiota, another key environmental factor, may be considered as a converging element. Studies have shown that cancer susceptibility may be induced in germ free mice colonized with the gut microbiota from high-fat diet-fed mice. Suggested mechanisms may involve inflammation, immunity changes, lipogenic substrates, and adipogenesis. Summary: Cancer development is a complex process that may be under the control of previously unthought factors such as the gut microbiota. Whether specific intervention targeting the gut microbiota may reduce adipose tissue-driven cancer is an interesting strategy that remains to be proven. PMID- 29188140 TI - Forelimb muscle and joint actions in Archosauria: insights from Crocodylus johnstoni (Pseudosuchia) and Mussaurus patagonicus (Sauropodomorpha). AB - Many of the major locomotor transitions during the evolution of Archosauria, the lineage including crocodiles and birds as well as extinct Dinosauria, were shifts from quadrupedalism to bipedalism (and vice versa). Those occurred within a continuum between more sprawling and erect modes of locomotion and involved drastic changes of limb anatomy and function in several lineages, including sauropodomorph dinosaurs. We present biomechanical computer models of two locomotor extremes within Archosauria in an analysis of joint ranges of motion and the moment arms of the major forelimb muscles in order to quantify biomechanical differences between more sprawling, pseudosuchian (represented the crocodile Crocodylus johnstoni) and more erect, dinosaurian (represented by the sauropodomorph Mussaurus patagonicus) modes of forelimb function. We compare these two locomotor extremes in terms of the reconstructed musculoskeletal anatomy, ranges of motion of the forelimb joints and the moment arm patterns of muscles across those ranges of joint motion. We reconstructed the three dimensional paths of 30 muscles acting around the shoulder, elbow and wrist joints. We explicitly evaluate how forelimb joint mobility and muscle actions may have changed with postural and anatomical alterations from basal archosaurs to early sauropodomorphs. We thus evaluate in which ways forelimb posture was correlated with muscle leverage, and how such differences fit into a broader evolutionary context (i.e. transition from sprawling quadrupedalism to erect bipedalism and then shifting to graviportal quadrupedalism). Our analysis reveals major differences of muscle actions between the more sprawling and erect models at the shoulder joint. These differences are related not only to the articular surfaces but also to the orientation of the scapula, in which extension/flexion movements in Crocodylus (e.g. protraction of the humerus) correspond to elevation/depression in Mussaurus. Muscle action is highly influenced by limb posture, more so than morphology. Habitual quadrupedalism in Mussaurus is not supported by our analysis of joint range of motion, which indicates that glenohumeral protraction was severely restricted. Additionally, some active pronation of the manus may have been possible in Mussaurus, allowing semi pronation by a rearranging of the whole antebrachium (not the radius against the ulna, as previously thought) via long-axis rotation at the elbow joint. However, the muscles acting around this joint to actively pronate it may have been too weak to drive or maintain such orientations as opposed to a neutral position in between pronation and supination. Regardless, the origin of quadrupedalism in Sauropoda is not only linked to manus pronation but also to multiple shifts of forelimb morphology, allowing greater flexion movements of the glenohumeral joint and a more columnar forelimb posture. PMID- 29188141 TI - The relationship between egg size and helper number in cooperative breeders: a meta-analysis across species. AB - Background: Life history theory predicts that mothers should adjust reproductive investment depending on benefits of current reproduction and costs of reduced future reproductive success. These costs and benefits may in turn depend on the breeding female's social environment. Cooperative breeders provide an ideal system to test whether changes in maternal investment are associated with the social conditions mothers experience. As alloparental helpers assist in offspring care, larger groups might reduce reproductive costs for mothers or alternatively indicate attractive conditions for reproduction. Thus, mothers may show reduced (load-lightening) or increased (differential allocation) reproductive investment in relation to group size. A growing number of studies have investigated how cooperatively breeding mothers adjust pre-natal investment depending on group size. Our aim was to survey these studies to assess, first, whether mothers consistently reduce or increase pre-natal investment when in larger groups and, second, whether these changes relate to variation in post-natal investment. Methods: We extracted data on the relationship between helper number and maternal pre-natal investment (egg size) from 12 studies on 10 species of cooperatively breeding vertebrates. We performed meta-analyses to calculate the overall estimated relationship between egg size and helper number, and to quantify variation among species. We also tested whether these relationships are stronger in species in which the addition of helpers is associated with significant changes in maternal and helper post-natal investment. Results: Across studies, there is a significant negative relationship between helper number and egg size, suggesting that in most instances mothers show reduced reproductive investment in larger groups, in particular in species in which mothers also show a significant reduction in post-natal investment. However, even in this limited sample, substantial variation exists in the relationship between helper number and egg size, and the overall effect appears to be driven by a few well-studied species. Discussion: Our results, albeit based on a small sample of studies and species, indicate that cooperatively breeding females tend to produce smaller eggs in larger groups. These findings on prenatal investment accord with previous studies showing similar load-lightening reductions in postnatal parental effort (leading to concealed helper effects), but do not provide empirical support for differential allocation. However, the considerable variation in effect size across studies suggests that maternal investment is mitigated by additional factors. Our findings indicate that variation in the social environment may influence life-history strategies and suggest that future studies investigating within-individual changes in maternal investment in cooperative breeders offer a fruitful avenue to study the role of adaptive plasticity.

AB - Background: We examined the United States National Health and Nutrition Examination Survey (NHANES) database to determine factors associated with rheumatoid arthritis (RA) in adults 20 to 55 years of age. Methods: NHANES data collected between 2007 and 2014, excluding the 2011-2012 period, were used. Subjects were divided into those with and without RA. Demographic, clinical, and lifestyle factors were compared between the groups. Results: After applying inclusion/exclusion criteria, 8,789 persons were included in the study (8,483 without RA, 306 with RA). Multivariable analysis indicated that advanced age (odds ratio [OR] = 1.09, 95% CI [1.07-1.11], P < 0.001), regular smoking (OR = 2.19, 95% CI [1.49-3.21], P < 0.001), diabetes (OR = 2.00, 95% CI [1.35-2.95], P = 0.001), obesity (reference, normal or underweight; OR = 3.31, 95% CI [2.05 5.36], P < 0.001), and osteoporosis (OR = 3.68, 95% CI [1.64-8.22], P = 0.002) were positively associated with RA. Covered by health insurance (OR = 1.81, 95% CI [1.12-2.93], P = 0.016) and living in poverty (OR = 2.96, 95% CI [1.88-4.65], P < 0.001) were also associated with having RA. Mexican American, Hispanic white or other Hispanic ethnicity (reference, non-Hispanic white; OR = 0.54, 95% CI [0.31-0.96], P = 0.036), appropriate sleep duration (about 6-11 h, OR = 0.46, 95% CI [0.32-0.65], P < 0.001), and insufficient vitamin A intake (reference, recommended; OR = 0.70, 95% CI [0.50-0.98], P = 0.036) were negatively associated with RA. Discussion: Some factors associated with RA are potentially modifiable. PMID- 29188143 TI - The impact of self-incompatibility systems on the prevention of biparental inbreeding. AB - Inbreeding in hermaphroditic plants can occur through two different mechanisms: biparental inbreeding, when a plant mates with a related individual, or self fertilization, when a plant mates with itself. To avoid inbreeding, many hermaphroditic plants have evolved self-incompatibility (SI) systems which prevent or limit self-fertilization. One particular SI system-homomorphic SI-can also reduce biparental inbreeding. Homomorphic SI is found in many angiosperm species, and it is often assumed that the additional benefit of reduced biparental inbreeding may be a factor in the success of this SI system. To test this assumption, we developed a spatially-explicit, individual-based simulation of plant populations that displayed three different types of homomorphic SI. We measured the total level of inbreeding avoidance by comparing each population to a self-compatible population (NSI), and we measured biparental inbreeding avoidance by comparing to a population of self-incompatible plants that were free to mate with any other individual (PSI). Because biparental inbreeding is more common when offspring dispersal is limited, we examined the levels of biparental inbreeding over a range of dispersal distances. We also tested whether the introduction of inbreeding depression affected the level of biparental inbreeding avoidance. We found that there was a statistically significant decrease in autozygosity in each of the homomorphic SI populations compared to the PSI population and, as expected, this was more pronounced when seed and pollen dispersal was limited. However, levels of homozygosity and inbreeding depression were not reduced. At low dispersal, homomorphic SI populations also suffered reduced female fecundity and had smaller census population sizes. Overall, our simulations showed that the homomorphic SI systems had little impact on the amount of biparental inbreeding in the population especially when compared to the overall reduction in inbreeding compared to the NSI population. With further study, this observation may have important consequences for research into the origin and evolution of homomorphic self-incompatibility systems. PMID- 29188144 TI - An efficient pipeline to generate data for studies in plastid population genomics and phylogeography. AB - Premise of the study: Seed dispersal contributes to gene flow and is responsible for colonization of new sites and range expansion. Sequencing chloroplast haplotypes offers a way to estimate contributions of seed dispersal to population genetic structure and enables studies of population history. Whole-genome sequencing is expensive, but resources can be conserved by pooling samples. Unfortunately, haplotype associations among single-nucleotide polymorphisms (SNPs) are lost in pooled samples, and treating SNP allele frequencies as independent markers provides biased estimates of genetic structure. Methods: We developed sampling methodologies and an application, CallHap, that uses a least squares algorithm to evaluate the fit between observed and predicted SNP allele frequencies from pooled samples based on haplotype network phylogeny structure, thus enabling pooling for chloroplast sequencing for large-scale studies of chloroplast genomic variation. This method was tested using artificially constructed test networks and pools, and pooled samples of Lasthenia californica (California goldfields) from southern Oregon, USA. Results: CallHap reliably recovered network topologies and haplotype frequencies from pooled samples. Discussion: The CallHap pipeline allows for the efficient use of resources for estimation of genetic structure for studies using nonrecombining haplotypes such as intraspecific variation in chloroplast, mitochondrial, bacterial, or viral DNA. PMID- 29188145 TI - A three-dimensional spatial mapping approach to quantify fine-scale heterogeneity among leaves within canopies. AB - Premise of the study: The three-dimensional structure of tree canopies creates environmental heterogeneity, which can differentially influence the chemistry, morphology, physiology, and/or phenology of leaves. Previous studies that subdivide canopy leaves into broad categories (i.e., "upper/lower") fail to capture the differences in microenvironments experienced by leaves throughout the three-dimensional space of a canopy. Methods: We use a three-dimensional spatial mapping approach based on spherical polar coordinates to examine the fine-scale spatial distributions of photosynthetically active radiation (PAR) and the concentration of ultraviolet (UV)-absorbing compounds (A300) among leaves within the canopies of black mangroves (Avicennia germinans). Results: Linear regressions revealed that interior leaves received less PAR and produced fewer UV absorbing compounds than leaves on the exterior of the canopy. By allocating more UV-absorbing compounds to the leaves on the exterior of the canopy, black mangroves may be maximizing UV-protection while minimizing biosynthesis of UV absorbing compounds. Discussion: Three-dimensional spatial mapping provides an inexpensive and portable method to detect fine-scale differences in environmental and biological traits within canopies. We used it to understand the relationship between PAR and A300, but the same approach can also be used to identify traits associated with the spatial distribution of herbivores, pollinators, and pathogens.

AB - Premise of the study: Polymorphic microsatellite markers were developed to reveal the genetic diversity of extant populations and the mating system of Sinowilsonia henryi (Hamamelidaceae). Methods and Results: In this study, nuclear simple sequence repeat (SSR) markers were developed using the Illumina high-throughput sequencing technique (RNA-Seq). The de novo-assembled transcriptome generated a total of 64,694 unique sequences with an average length of 601 bp. A total of 2941 microsatellite loci were detected. Of the 121 tested loci, 13 loci were polymorphic and eight were monomorphic among 72 individuals representing three natural populations of the species. The number of alleles per locus ranged from one to four, and the observed and expected heterozygosity at population level were 0.00-1.00 and 0.10-0.66, respectively. Conclusions: The developed expressed sequence tag (EST)-SSRs will be useful for studying genetic diversity of S. henryi as well as assessing the mating system among Sinowilsonia species. PMID- 29188147 TI - Development and characterization of EST-SSR markers for Ottelia acuminata var. jingxiensis (Hydrocharitaceae). AB - Premise of the study: Simple sequence repeat (SSR) markers were derived from transcriptomic data for Ottelia acuminata (Hydrocharitaceae), a species comprising five endemic and highly endangered varieties in China. Methods and Results: Sixteen novel SSR markers were developed for O. acuminata var. jingxiensis. One to eight alleles per locus were found, with a mean of 2.896. The observed and expected heterozygosity ranged from 0.000 to 1.000 and 0.000 to 0.793, respectively. Interestingly, in cross-varietal amplification, 13 out of the 16 loci were successfully amplified in O. acuminata var. acuminata, and 12 amplified in each of the other three varieties of O. acuminata. Conclusions: These newly developed SSR markers will facilitate further study of genetic variation and provide important genetic data needed for appropriate conservation of natural populations of all varieties of O. acuminata. PMID- 29188148 TI - Development, characterization, and cross-amplification of 16 microsatellite primers for Atriplex tatarica (Amaranthaceae). AB - Premise of the study: Microsatellite primers were developed to characterize the genetic diversity and structure of the annual herb Atriplex tatarica (Amaranthaceae) and to facilitate ecological and evolutionary studies of A. tatarica and its relatives. Methods and Results: Sixteen novel microsatellite primers were developed for A. tatarica based on high-throughput sequencing of enriched libraries. All markers were polymorphic, with the number of alleles per locus ranging from three to 25 and observed and expected heterozygosity ranging from 0.08 to 0.74 and 0.10 to 0.87, respectively. In addition, some of these loci were successfully amplified and showed polymorphisms in four Atriplex and seven Chenopodium species. Conclusions: The microsatellite markers published here will be useful in assessing genetic diversity, structure, and gene flow within and across populations of A. tatarica, as well as in other species of Atriplex and the related genus Chenopodium.

AB - Premise of the study: Microsatellite markers were developed for population genetic analysis in the rare shrub Styphelia longissima (Ericaceae). Methods and Results: We generated ca. 2.5 million sequence reads using a Personal Genome Machine semiconductor sequencer. Using the QDD pipeline, we designed primers for >12,000 sequences with PCR product lengths of 80-480 bp. From these, 30 primer pairs were selected and screened using PCR; of these, 16 loci were found to be polymorphic, four loci were monomorphic, and 10 loci did not amplify reliably for S. longissima. For a sample of 57 plants from the only known population, the number of alleles observed for these 16 loci ranged from two to 21 and expected heterozygosity ranged from 0.49 to 0.91. These markers were also amplified in Astroloma xerophyllum, a closely related species. Conclusions: These markers will be used to characterize population genetic variation, spatial genetic structure, mating system parameters, and dispersal to aid in the management and conservation of the rare shrub S. longissima.

AB - Adenoid cystic carcinoma (ACC) is generally treated with surgical resection followed by postoperative radiotherapy. In cases where surgical management is precluded due to the location of the tumor and/or patient factors, radiation therapy can be offered to achieve local control.

PMID- 29188151 TI - Arachnoid Cyst and Psychosis. AB - Few case reports discuss suspected psychiatric disturbances secondary to arachnoid cysts. To the best of our knowledge, psychosis from arachnoid cysts has not been reported in the recent literature. This case report discusses our experience with a 55-year-old male patient who manifested multiple psychotic episodes suspected in association with an arachnoid cyst. During the initial examinations, a computed tomography (CT) scan of his head revealed a relatively large left anterior superior arachnoid cyst with a mass effect on the frontal lobe. Despite multiple trials of combinations of mood stabilizers and psychotropic medications, the patient continued to deteriorate. We ordered a repeat CT of his head along with a magnetic resonance image and consulted a neurosurgeon for a possible surgical intervention. The neurosurgeon concluded that the patient's psychiatric symptoms were unrelated to the arachnoid cyst. While we were unable to determine the etiology of our patient's psychosis, we believe that the arachnoid cyst played at least some part, as evidenced by reports in the literature. Future advancements in radiological technology may allow for a better exploration of the causal relationship between psychiatric illnesses and brain lesions.

AB - This manuscript reports on a patient with a metastatic gastrointestinal stromal tumor (GIST) refractory to standard first-line treatment, who underwent a gallium 68 scan based on pre-clinical data of somatostatin receptor (SSTR) expression in such tumors. The gallium-68 DOTATATE scan determined significant somatostatin receptor avidity as hypothesized, suggesting that this imaging modality may be used as an option for diagnostic and follow-up purposes in GIST patients. In addition, peptide receptor-mediated radiotherapy (177Lu-PPRT) via SSTR may provide a novel treatment strategy in carefully selected SSTR-avid GIST patients with thyrosine kinase inhibitor (TKI)-resistant tumors such as this case, and this warrants further investigation in novel clinical trial concepts.

AB - A retained intra-abdominal foreign body is a common occurrence that is frequently underreported due to its medicolegal implications. Sponges, gauzes, surgical instruments, abdominal drains, etc. have been reported in the literature. The most common presentation for a retained intra-abdominal foreign body is postoperative abdominal infections or bleeding, frequently seen in the immediate postoperative period. Most of these foreign bodies are removed by exploratory laparotomy owing to recent abdominal surgeries or presentation as complicated abdominal masses. Here, we report a case with retained intra-abdominal drains for 15 years with minimal symptoms presenting as an intermittent abdominal pain; the drains were removed using laparoscopic intervention. PMID- 29188156 TI - Hypoglycemia-associated In-stent Thrombosis: Are We Doing Too Much? AB - Diabetes mellitus is one of the most common modifiable risk factors for coronary artery disease, and its prevalence is rising globally. Persistent hyperglycemia has a well-established cardiovascular risk, and its treatment plays an important role in the prevention of future cardiovascular events. While we improved microvascular complications such as retinopathy, nephropathy, and neuropathy by stringent blood glucose control, the cardiovascular morbidity and mortality in diabetics remain high. Hypoglycemia, on the other hand, is an important side effect of pharmaceutical blood glucose control, especially those who are treated with insulin. Here, we report the case of a 38-year-old man with type 1 diabetes presenting twice with acute ST-elevation myocardial infarction, both in the setting of documented hypoglycemia. There are reported cases of acute cardiovascular events or silent myocardial ischemia associated with hypoglycemia, and we wish to raise awareness for clinicians who treat this special population of patients.

AB - Objective To predict changes in the quality of life scores of hemodialysis patients for the coming month and the development of an early warning system using machine learning Methods It was a prospective cohort study (one-month duration) at the dialysis center of a tertiary care hospital in Pakistan. The study started on 1st October 2016. About 78 patients have been enrolled till now. Bachelor of Medicine and Bachelor of Surgery (MBBS) qualified doctors administered a proforma with demographics and the validated Urdu version of World Health Organization Quality Of Life-BREF (WHOQOL-BREF). It was to be repeated after one month to the same patient by the same investigator. Simple statistics were computed using SPSS version 24 (IBM Corp., Armonk, NY) while machine learning was performed using R (version 3.0) and Orange (version 3.1). Results Using machine learning algorithms, two models (classification tree and Naive Bayes) were generated to predict an increase or decrease of 5% in a patient's WHOQOL-BREF score over one month. The classification tree was selected as the most accurate model with an area under curve (AUC) of 83.3% (accuracy: 81.9%) for the prediction of 5% increase in QOL and an AUC of 76.2% (accuracy: 81.8%) for the prediction of 5% decrease in QOL over the coming month. The factors associated with an increase of QOL by 5% or more over the next month included younger age (<19 years) and higher iron sucrose doses (>278mg/month). Drops in psychological, physical, and social domain scores lead to a decrease of 5% or more in QOL scores over the following month. Conclusion An early warning system, dialysis data interpretation for algorithmic-prediction on quality of life (DIAL) was built for the early detection of deteriorating QOL scores in the hemodialysis population using machine learning algorithms. The model pointed out that working on psychological and environmental domains, in particular, may prevent the drop in QOL scores from occurring. DIAL, if implemented on a larger scale, is expected to help patients in terms of ensuring a better QOL and in reducing the financial burden in the long term.

A four-dimensional computed tomography scan with three dimensional reconstruction showed two parathyroid glands (one right and one left) and anatomic variation from previous surgery. Revision surgery was performed revealing the parathyroid glands as expected from the preoperative three dimensional reconstruction. After surgery, the patient recovered well, and preoperative symptoms resolved. The use of three-dimensional computed tomography reconstruction provided accurate localization of the parathyroid glands and surrounding anatomic structures. This resulted in decreased preoperative planning cost, operative time, and estimated blood loss typical for patients who have multiple preoperative imaging studies. PMID- 29188160 TI - Severe Hyperthyroidism Masquerading as Acute Bulbar Weakness. AB - The stroke occurs in nearly 800,000 patients per year in the United States with significant morbidity if not treated and managed in a time sensitive manner. Acute bulbar weakness can be a common presenting manifestation of acute stroke and transient ischemic attack. However, up to 30% of the patients presenting with symptoms concerning for stroke could be displaying a disease process that mimics the stroke. These disorders include hypoglycemia, seizures, complicated migraines, and endocrinopathies such as thyroid disease. If neuroimaging fails to show evidence of an acute infarct, these stroke mimics should be considered. When acute bulbar weakness occurs in the setting of severe hyperthyroidism, the treatment of this process can result in rapid improvement of symptoms. PMID- 29188161 TI - An Invasive Case of Left-Sided Endocarditis Caused by Pseudomonas aeruginosa in a Patient with History of Intravenous Drug Abuse. AB - Infective endocarditis, caused by Pseudomonas aeruginosa, is rarely seen in clinical practice. It has been reported mainly in intravenous drug abusers (IVDA). We present a case of a 63-year-old male who presented with abdominal pain and fever. Computed tomography (CT) abdomen showed splenic and renal infarct. The blood culture grew Pseudomonas aeruginosa. A transthoracic echocardiogram showed aortic insufficiency with 13 mm mobile vegetation. The patient was started on ceftazidime and tobramycin and, later on, surgery was done for aortic valve replacement. His stay was complicated by multiple hemorrhagic emboli in the brain. This case highlights the importance of the early diagnosis and management of infective endocarditis caused by Pseudomonas aeruginosa. PMID- 29188162 TI - Obstructive Sleep Apnea: An Unusual Cause of Hemorrhagic Stroke. AB - Stroke is one of the most common causes of mortality and morbidity worldwide. Hemorrhagic stroke comprises 10-20% of strokes. Here, we present a case report of hemorrhagic stroke that may have been secondary to untreated Obstructive Sleep Apnea (OSA) in a young man with no other cardiovascular risk factors or features of metabolic syndrome. A 32-year-old man was admitted for hemorrhagic stroke. An initial thorough workup for the etiology of stroke was inconclusive. Eventually, a polysomnography was done, which demonstrated OSA suggesting that untreated OSA may have contributed to his stroke. OSA may cause hemorrhagic stroke by nocturnal blood pressure surge. So, all physicians should consider doing polysomnography for unexplained hemorrhagic stroke or in patients at risk. Diagnosing and treating OSA would be critical in preventing hemorrhagic stroke and its recurrences. PMID- 29188163 TI - Notalgia Paresthetica: A Novel Approach to Treatment with Cryolipolysis. AB - Notalgia paresthetica, a neurosensory syndrome that typically occurs on the upper back, has multiple clinical symptoms with variable degrees of expression in each individual afflicted with the condition. The involved site is usually hyperpigmented and is associated with burning, coldness, hypoesthesia, increased pain, pruritus and/or tingling. In the affected area, the number of nerve fibers may be increased and the cutaneous sensory nerves are altered secondary to localized impingement, central injury, or both. Although multiple therapeutic approaches for notalgia paresthetica have been described, none specifically address the essential pathogenesis of the condition-the altered cutaneous nerves. Cryolipolysis is a well-tolerated nonsurgical technique to reduce the subcutaneous fat layer. Selective apoptosis of adipocytes occurs since the lipid rich fat cells are more susceptible to cold injury than the surrounding water rich cells. Not only a marked decrease in pain sensitivity but also a sustained reduction in the density of myelinated and unmyelinated cutaneous nerves has been observed in cryolipolysis-treated skin. Therefore, cryolipolysis is a logical approach to the treatment of notalgia paresthetica. One or more cryolipolysis treatments may be necessary for complete or partial resolution of the individual's notalgia paresthetica-related cutaneous symptoms. In conclusion, evaluation of cryolipolysis as a noninvasive treatment of patients with notalgia paresthetica is warranted. PMID- 29188164 TI - Developing an Undergraduate Ultrasound Curriculum: A Needs Assessment. AB - Background The introduction of ultrasound into the undergraduate medical school curriculum is gaining momentum in North America. At present, many institutions are teaching ultrasound to undergraduate medical students using a traditional framework designed to instruct practicing clinicians, or have modeled the curriculum on other universities. This approach is not based on educational needs or supported by evidence. Methods Using a descriptive, cross-sectional survey of stakeholder groups, we assessed the perceived relevance of various ultrasound skills and the attitude towards implementing an undergraduate ultrasound curriculum at our university. Results One hundred and fifty survey respondents representing all major stakeholder groups participated. All medical students, 97% of residents and 82% of educators agreed that the introduction of an ultrasound curriculum would enhance medical students' understanding of anatomy and physiology. All clinical medical students and residents, 92% of preclinical medical students, and 82% of educators agreed that the curriculum should also include clinical applications of ultrasound. Participants also indicated their preferences for specific curriculum content based on their perceived needs. Conclusion An integrated undergraduate ultrasound curriculum composed of specific preclinical and clinical applications was deemed appropriate for our university following a comprehensive needs assessment. Other universities planning such curricula should consider employing a needs assessment to provide direction for curriculum need and content. PMID- 29188165 TI - Diffusion Tensor Imaging for Ruptured Cerebral Arteriovenous Malformation. AB - Non-ruptured arteriovenous malformations (AVMs) rarely cause tract disruption. Few studies have described how ruptured AVMs influence white matter (WM) tract morphology. We reviewed consecutive AVM cases treated at a tertiary care hospital where diffusion tensor imaging (DTI) tractography was obtained preoperatively. DTI was performed using the Synaptive Plan (Synaptive Medical Inc., Toronto, Canada). Quality control was performed by clinical application specialist. Perinidal fractional anisotropy (FA) value of corticospinal tracts (CST) was obtained. A reference FA value was obtained from the corresponding area on the contralateral side. Images were evaluated by a consultant neuroradiologist. Radiological findings were correlated with clinical findings. White matter morphology was described by a consultant neuroradiologist. All three cases included in the study had a history of haemorrhage in the past. Two patients had disruption of CST and presented with a significant neurological deficit. In one patient FA value of CST around the nidus was comparable to the contralateral side and did not show any neurological deficit. DTI integrated neuronavigation was used to plan the trajectory and complete resection of the AVM with excellent postoperative recovery. PMID- 29188166 TI - Tractography for Optic Radiation Preservation in Transcortical Approaches to Intracerebral Lesions. AB - We present a case of intraventricular meningioma resected via a transcortical approach using tractography for optic radiation and arcuate fasciculus preservation. We include a review of the literature. A 54-year-old woman with a history of breast cancer presented with gait imbalance. Workup revealed a mass in the atrium of the left lateral ventricle consistent with a meningioma. Whole brain automated diffusion tensor imaging (DTI) was used to plan a transcortical resection while sparing the optic radiations and arcuate fasciculus. A left posterior parietal craniotomy was performed using the Synaptive BrightMatterTM frameless navigation (Synaptive Medical, Toronto, Canada) to minimally disrupt the white matter pathways. A gross total resection was achieved. Postoperatively, the patient had temporary right upper extremity weakness, which improved, and her visual fields and speech remained intact. Pathology confirmed a World Health Organization (WHO) Grade I meningothelial meningioma. While a thorough understanding of cortical anatomy is essential for safe resection of eloquent or deep-seated lesions, significant variability in fiber bundles, such as optic radiations and the arcuate fasciculus, necessitates a more individualized understanding of a patient's potential surgical risk. The addition of enhanced DTI to the neurosurgeon's armamentarium may allow for more complete resections of difficult intracerebral lesions while minimizing complications, such as visual deficit. PMID- 29188167 TI - Reconstruction of the Ascending Reticular Activating System with Diffusion Tensor Tractography in Patients with a Disorder of Consciousness after Traumatic Brain Injury. AB - This work describes the reconstruction of the ascending reticular activating system (ARAS) with diffusion tensor tractography in three patients with altered consciousness after traumatic brain injury. A diffusion tensor tractography was performed in three patients with impaired consciousness after a severe traumatic brain injury. A 1.5 T scanner was used to obtain the tensor sequences; axial tensors were acquired. Post-processing was performed, and the mean fractional anisotropy (FA) values were recorded. The FA maps were used to do a manual tracing of the following regions of interest (ROIs): the ventromedial midbrain, the anterior thalamus, and the hypothalamus. Case 1 presented destruction of the right dorsal and ventral tegmental tracts as well as destruction of the right middle forebrain bundle, case 2 had destruction of the right dorsal tegmental tract, and case 3 had destruction of the bilateral ventral and dorsal tegmental tracts, as well as destruction of the right middle forebrain bundle. The affected fibers of the ascending reticular activating system with diffuse axonal injury and the FA values abnormalities in the ascending reticular activating system in three patients with a disorder of consciousness (DOC) after traumatic brain injury are described.

PMID- 29188169 TI - Analysis of Social Communication Questionnaire (SCQ) Screening for Children Less Than Age 4. AB - Purpose of Review: The Social Communication Questionnaire (SCQ) is a screener for Autism spectrum disorder (ASD) validated for age 4.0 +. There is a clinical need for an ASD screener for children beyond the 30-month age limit of the M-CHAT-R/F. We evaluate the literature on the use of the SCQ in children < 4.0 years. Recent Findings: Recent studies have used very large samples; included typically developing children, rather than just those with developmental disorders; compared the SCQ Lifetime and Current versions; and increased scrutiny of internal validity. Summary: The sensitivity-specificity balance in distinguishing between ASD and other developmental disorders is poor, which has led to development of abbreviated versions of the SCQ; however, sensitivity-specificity balance is better in a more general population. The SCQ Lifetime (not Current) version should be used. Future research relating should focus on further validation of the SCQ as a screener for children 30-48 months. PMID- 29188170 TI - The Role of Climate in the Epidemiology of Melioidosis. AB - Purpose of Review: Melioidosis epidemiology is susceptible to climate change through direct and indirect effects on human encounter with the causative agent, Burkholderia pseudomallei. This review describes the current depth of knowledge and recent advances in the understanding of this relationship and applies it to observations of melioidosis in Western Australia. Recent Findings: High maximum rainfall and dense cloud cover have been shown to predict environmental presence of B. pseudomallei and cases of melioidosis, probably through correspondingly high moisture levels in B. pseudomallei-receptive soils. Increased melioidosis cases have been observed following storms in Taiwan and cyclones in the Australian Northern Territory and strengthen the association between melioidosis and extreme weather events. Indirect weather effects contribute to bacterial exposure through mechanisms such as increasing B. pseudomallei output from water seeps after heavy rain or localised flooding. Climate and weather have been directly implicated in dissemination of B. pseudomallei and cases of melioidosis in several notable events in Western Australia. Over a 10-year surveillance period, the cases that lay in the path of a tropical cyclone co-located with cyclone systems that repeatedly crossed the Western Australian coast. Cyclone associated cases were caused by different B. pseudomallei MLST genotypes, arguing against airborne dissemination from a common source. Summary: Predicted increases in temperature, changes in global precipitation patterns and an increased incidence of extreme weather events are expected to change melioidosis epidemiology. Further studies of the physical geographic drivers of melioidosis will deepen understanding of the impact of climate on melioidosis. PMID- 29188171 TI - Managing persistent wound leakage after total knee and hip arthroplasty. Results of a nationwide survey among Dutch orthopaedic surgeons. AB - Background: Persistent wound leakage after joint arthroplasty is a scantily investigated topic, despite the claimed relation with a higher risk of periprosthetic joint infection. This results in a lack of evidence-based clinical guidelines for the diagnosis and treatment of persistent wound leakage after joint arthroplasty. Without such guideline, clinical practice in orthopaedic hospitals varies widely. In preparation of a nationwide multicenter randomized controlled trial on the optimal treatment of persistent wound leakage, we evaluated current Dutch orthopaedic care for persistent wound leakage after joint arthroplasty. Methods: We conducted a questionnaire-based online survey among all 700 members of the Netherlands Orthopaedic Association, consisting of 23 questions on the definition, classification, diagnosis and treatment of persistent wound leakage after joint arthroplasty. Results: The questionnaire was completed by 127 respondents, representing 68% of the Dutch hospitals that perform orthopaedic surgery. The results showed wide variation in the classification, definition, diagnosis and treatment of persistent wound leakage among Dutch orthopaedic surgeons. 56.7% of the respondents used a protocol for diagnosis and treatment of persistent wound leakage, but only 26.8% utilized the protocol in every patient. Most respondents (59.1%) reported a maximum period of persistent wound leakage before starting non-surgical treatment of 3 to 7 days after index surgery and 44.1% of respondents reported a maximum period of wound leakage of 10 days before converting to surgical treatment. Conclusions: The wide variety in clinical practice underscores the importance of developing an evidence based clinical guideline for the diagnosis and treatment of persistent wound leakage after joint arthroplasty. To this end, a nationwide multicenter randomized controlled trial will be conducted in the Netherlands, which may provide evidence on this important and poorly understood topic. PMID- 29188172 TI - Effect of Sonication on the Elution of Antibiotics from Polymethyl Methacrylate (PMMA). AB - Background: In the setting of prosthetic joint infections treated with a two stage procedure, spacers can be sonicated after removal. We hypothesize that the sonication process may cause an increased elution of antibiotics from the spacer, leading to elevated concentrations of antibiotics in the sonication fluid inhibiting bacterial growth. We aimed to evaluate in vitro the influence of sonication on the elution of antibiotics from polymethyl methacrylate (PMMA) over time and to determine whether these concentrations are above the minimum inhibitory concentrations (MIC) for microorganisms relevant in prosthetic joint infections. Methods: PMMA blocks impregnated with vancomycin, fosfomycin, gentamicin or daptomycin were incubated in phosphate-buffered saline (PBS) at 37 degrees C for up to 6 weeks. PBS was changed once a week. Concentrations were determined from samples of each antibiotic every week, and after 5 minutes of sonication at 2, 4 and 6 weeks. Results: With sonication there was a trend toward an increase of the elution of antibiotics. This increase was significant for vancomycin at 2 and 4 weeks (p=0.008 and 0.002 respectively) and for fosfomycin at 2 weeks (p=0.01). Conclusion: The effect of sonication could play a role in clinical results, especially for daptomycin and gentamicin for which the MIC is close to the concentration of antibiotics at 4 and 6 weeks. We conclude that elution of antibiotics from PMMA along with the effect of sonication could inhibit bacterial growth from spacers, resulting in false negative results in the setting of two-stage exchange procedures for prosthetic joint infections. PMID- 29188173 TI - Influence of Sonication on Bacterial Regrowth from Antibiotic Loaded PMMA Scaffolds - An In-vitro Study. AB - Periprosthetic joint infection (PJI) is one of the most challenging complications after joint replacement. However, when treated correctly, chances of recovery are good. The most important step in correct diagnosis and management of PJI is the detection of the causative germ. In the last years, the use of sonication in the diagnostic process has become more important. However, this diagnostic methodology has been controversially discussed when used in combination with antibiotic loaded bone cement (PMMA), which is frequently used in joint replacement surgeries. The aim of this study was thus to analyse in vitro bacterial growth in sonication fluid cultures obtained from antibiotic loaded PMMA which were contaminated with various bacterial biofilms. Sonication fluid obtained from antibiotic loaded PMMA (Copal G+V and Copal G+C) and plain Palacos R (control) contaminated either with S. aureus, E. faecalis, S. sanguinis or P.acnes, were analysed for bacterial re-growth in a standardised in-vitro setting. In vitro bacterial growth was not interfered by released antibiotics from sonication of antibiotic loaded PMMA for S. aureus, E. faecalis and S. sanguinis. However, for P. acnes bacterial counts were affected by the released antibiotics as well as by the time delay between sonication and analysis. The in vitro data suggest sonication to be an easy and sensitive diagnostic modality to detect easy-to-detect bacteria, however, results are alarming for the difficult to-detect bacteria P. acnes, indicating that further attention and research is necessary to improve the detection of difficult-to-detect bacteria. PMID- 29188174 TI - Diagnosis Of Persistent Infection In Prosthetic Two-Stage Exchange: PCR analysis of Sonication fluid From Bone Cement Spacers. AB - Introduction: When treating periprosthetic joint infections with a two-stage procedure, antibiotic-impregnated spacers are used in the interval between removal of prosthesis and reimplantation. According to our experience, cultures of sonicated spacers are most often negative. The objective of our study was to investigate whether PCR analysis would improve the detection of bacteria in the spacer sonication fluid. Methods: A prospective monocentric study was performed from September 2014 to January 2016. Inclusion criteria were two-stage procedure for prosthetic infection and agreement of the patient to participate in the study. Beside tissues samples and sonication, broad range bacterial PCRs, specific S. aureus PCRs and Unyvero-multiplex PCRs were performed on the sonicated spacer fluid. Results: 30 patients were identified (15 hip, 14 knee and 1 ankle replacements). At reimplantation, cultures of tissue samples and spacer sonication fluid were all negative. Broad range PCRs were all negative. Specific S. aureus PCRs were positive in 5 cases. We had two persistent infections and four cases of infection recurrence were observed, with bacteria different than for the initial infection in three cases. Conclusion: The three different types of PCRs did not detect any bacteria in spacer sonication fluid that was culture negative. In our study, PCR did not improve the bacterial detection and did not help to predict whether the patient will present a persistent or recurrent infection. Prosthetic 2-stage exchange with short interval and antibiotic impregnated spacer is an efficient treatment to eradicate infection as both culture- and molecular-based methods were unable to detect bacteria in spacer sonication fluid after reimplantation. PMID- 29188176 TI - Nano-sized Indocyanine Green J-aggregate as a One-component Theranostic Agent. AB - The development of biocompatiable efficient photothermal coupling agent (PCA) for image-guided photothermal therapy of cancer has gained increasing interests in recent years. Although various PCAs have been developed, the clinical translations of these materials have been largely hindered by the potential biosafety issues and challenges of scaling-up manufactures. In this research, we proposed nano-sized indocyanine green (ICG) J-aggregate (IJA) as a promising PCA which is fabricated by a very facile method using clinical-approved ICG as the only excipient. The as-prepared IJA remains stable in various solution and shows a ~115 nm red-shift in absorption peak compared to free ICG. Importantly, IJA can be disassociated into free ICG again after internalized into cells and exhibits high biosafety comparable to ICG. The IJA performs well for photothermal therapy both in vitro and in vivo. In addition, the IJA can also be used as a good photoacoustic contrast agent and internalization-responsive fluorescence probe. The facile preparation, high safety and excellent theranostic performance indicated that IJA might be a promising one-component agent for cancer theranostics. PMID- 29188175 TI - Current Progress of Virus-mimicking Nanocarriers for Drug Delivery. AB - Nanomedicines often involve the use of nanocarriers as a delivery system for drugs or genes for maximizing the therapeutic effect and/or minimizing the adverse effect. From drug administration to therapeutic activity, nanocarriers must evade the host's immune system, specifically and efficiently target and enter the cell, and release their payload into the cell cytoplasm by endosomal escape. These processes constitute the early infection stage of viruses. Viruses are a powerful natural nanomaterial for the efficient delivery of genetic information by sophisticated mechanisms. Over the past two decades, many virus inspired nanocarriers have been generated to permit successful drug and gene delivery. In this review, we summarize the early infection machineries of viruses, of which the part has so far been utilized for delivery systems. Furthermore, we describe basics and applications of the bio-nanocapsule, which is a hepatitis B virus-mimicking nanoparticle harboring nearly all activities involved in the early infection machineries (i.e., stealth activity, targeting activity, cell entry activity, endosomal escaping activity). PMID- 29188177 TI - Ultrasound-Stimulated Drug Delivery Using Therapeutic Reconstituted High-Density Lipoprotein Nanoparticles. AB - The abnormal tumor vasculature and the resulting abnormal microenvironment are major barriers to optimal chemotherapeutic drug delivery. It is well known that ultrasound (US) can increase the permeability of the tumor vessel walls and enhance the accumulation of anticancer agents. Reconstituted high-density lipoproteins (rHDL) nanoparticles (NPs) allow selective delivery of anticancer agents to tumor cells via their overexpressed scavenger receptor type B1 (SR-B1) receptor. The goal of this study is to investigate the potential of noninvasive US therapy to further improve delivery and tumor uptake of the payload from rHDL NPs, preloaded with an infrared dye (IR-780), aimed to establish a surrogate chemotherapeutic model with optical localization. Athymic nude mice were implanted orthotopically with one million breast cancer cells (MDA-MB-231/Luc). Three weeks later, animals were divided into seven groups with comparable mean tumor size: control, low, moderate, and high concentration of rHDL NPs alone groups, as well as these three levels of rHDL NPs plus US therapy groups (N = 7 to 12 animals per group), where low, moderate and high denote 5, 10, and 50 ug of the IR-780 dye payload per rHDL NP injection, respectively. The US therapy system included a single element focused transducer connected in series with a function generator and power amplifier. A custom 3D printed cone with an acoustically transparent aperture and filled with degassed water allowed delivery of focused US energy to the tumor tissue. US exposure involved a pulsed sequence applied for a duration of 5 min. Each animal in the US therapy groups received a slow bolus co-injection of MB contrast agent and rHDL NPs. Animals were imaged using a whole body optical system to quantify intratumoral rHDL NP accumulation at baseline and again at 1 min, 30 min, 24 h, and 48 h. At 48 h, all animals were euthanized and tumors were excised for ex vivo analysis. We investigated a noninvasive optical imaging method for monitoring the effects of US-stimulated drug delivery of IR 780 dye-loaded rHDL NPs in living animals. No change in optical imaging data was found in the control animals. However, there was considerable dye accumulation (surrogate drug) within 48 h in the low (5 ug), moderate (10 ug), and high (50 ug) rHDL NP concentration-dosed group animals (p < 0.09). With US therapy added to the experimental protocol, there was an additional and significant increase in local tumor drug uptake at 48 h (p < 0.02). Optical image data collected from ex vivo tumor samples confirmed tumor retention of the IR-780 dye-loaded rHDL NPs and correlated positively with in vivo optical imaging results (R2 > 0.69, p < 0.003). IR-780 dye extraction from the tumor tissue samples confirmed the in vivo and ex vivo US therapy findings. Overall, the addition of US therapy considerably improved local rHDL NP accumulation in tumor tissue. This study concludes that US mediated drug delivery can facilitate tumor uptake of rHDL NPs and more research is warranted to optimize the drug dosing schedule and the respective therapeutic protocols.

AB - Mucormycosis is a rare and life-threatening fungal infection of the Mucorales order occurring mainly in immunosuppressed patients. The most common forms are rhinocerebral but pulmonary or disseminated forms may occur. We report the case of a 61-year-old patient in whom pulmonary mucormycosis was diagnosed during his first-ever episode of diabetic ketoacidosis. While receiving liposomal amphotericin B, a sinusal aspergillosis due to Aspergillus fumigatus occurred. Evolution was slowly favorable under antifungal tritherapy by liposomal amphotericin B, posaconazole and caspofungin. PMID- 29188179 TI - Development of a high efficiency integration system and promoter library for rapid modification of Pseudomonas putida KT2440. AB - Pseudomonas putida strains are highly robust bacteria known for their ability to efficiently utilize a variety of carbon sources, including aliphatic and aromatic hydrocarbons. Recently, P. putida has been engineered to valorize the lignin stream of a lignocellulosic biomass pretreatment process. Nonetheless, when compared to platform organisms such as Escherichia coli, the toolkit for engineering P. putida is underdeveloped. Heterologous gene expression in particular is problematic. Plasmid instability and copy number variance provide challenges for replicative plasmids, while use of homologous recombination for insertion of DNA into the chromosome is slow and laborious. Further, most heterologous expression efforts to date typically rely on overexpression of exogenous pathways using a handful of poorly characterized promoters. To improve the P. putida toolkit, we developed a rapid genome integration system using the site-specific recombinase from bacteriophage Bxb1 to enable rapid, high efficiency integration of DNA into the P. putida chromosome. We also developed a library of synthetic promoters with various UP elements, -35 sequences, and -10 sequences, as well as different ribosomal binding sites. We tested these promoters using a fluorescent reporter gene, mNeonGreen, to characterize the strength of each promoter, and identified UP-element-promoter-ribosomal binding sites combinations capable of driving a ~150-fold range of protein expression levels. An additional integrating vector was developed that confers more robust kanamycin resistance when integrated at single copy into the chromosome. This genome integration and reporter systems are extensible for testing other genetic parts, such as examining terminator strength, and will allow rapid integration of heterologous pathways for metabolic engineering. PMID- 29188180 TI - Comparison of orthologous cyanobacterial aldehyde deformylating oxygenases in the production of volatile C3-C7 alkanes in engineered E. coli. AB - Aldehyde deformylating oxygenase (ADO) is a unique enzyme found exclusively in photosynthetic cyanobacteria, which natively converts acyl aldehyde precursors into hydrocarbon products embedded in cellular lipid bilayers. This capacity has opened doors for potential biotechnological applications aiming at biological production of diesel-range alkanes and alkenes, which are compatible with the nonrenewable petroleum-derived end-products in current use. The development of production platforms, however, has been limited by the relative inefficiency of ADO enzyme, promoting research towards finding new strategies and information to be used for rational design of enhanced pathways for hydrocarbon over-expression. In this work we present an optimized approach to study different ADO orthologs derived from different cyanobacterial species in an in vivo set-up in Escherichia coli. The system enabled comparison of alternative ADOs for the production efficiency of short-chain volatile C3-C7 alkanes, propane, pentane and heptane, and provided insight on the differences in substrate preference, catalytic efficiency and limitations associated with the enzymes. The work concentrated on five ADO orthologs which represent the most extensively studied cyanobacterial species in the field, and revealed distinct differences between the enzymes. In most cases the ADO from Nostoc punctiforme PCC 73102 performed the best in respect to yields and initial rates for the production of the volatile hydrocarbons. At the other extreme, the system harboring the ADO form Synechococcus sp. RS9917 produced very low amounts of the short-chain alkanes, primarily due to poor accumulation of the enzyme in E. coli. The ADOs from Synechocystis sp. PCC 6803 and Prochlorococcus marinus MIT9313, and the corresponding variant A134F displayed less divergence, although variation between chain-length preferences could be observed. The results confirmed the general trend of ADOs having decreasing catalytic efficiency towards precursors of decreasing chain-length, while expanding the knowledge on the species-specific traits, which may aid future pathway design and structure-based engineering of ADO for more efficient hydrocarbon production systems. PMID- 29188181 TI - Eliminating a global regulator of carbon catabolite repression enhances the conversion of aromatic lignin monomers to muconate in Pseudomonas putida KT2440. AB - Carbon catabolite repression refers to the preference of microbes to metabolize certain growth substrates over others in response to a variety of regulatory mechanisms. Such preferences are important for the fitness of organisms in their natural environments, but may hinder their performance as domesticated microbial cell factories. In a Pseudomonas putida KT2440 strain engineered to convert lignin-derived aromatic monomers such as p-coumarate and ferulate to muconate, a precursor to bio-based nylon and other chemicals, metabolic intermediates including 4-hydroxybenzoate and vanillate accumulate and subsequently reduce productivity. We hypothesized that these metabolic bottlenecks may be, at least in part, the effect of carbon catabolite repression caused by glucose or acetate, more preferred substrates that must be provided to the strain for supplementary energy and cell growth. Using mass spectrometry-based proteomics, we have identified the 4-hydroxybenzoate hydroxylase, PobA, and the vanillate demethylase, VanAB, as targets of the Catabolite Repression Control (Crc) protein, a global regulator of carbon catabolite repression. By deleting the gene encoding Crc from this strain, the accumulation of 4-hydroxybenzoate and vanillate are reduced and, as a result, muconate production is enhanced. In cultures grown on glucose, the yield of muconate produced from p-coumarate after 36 h was increased nearly 70% with deletion of the gene encoding Crc (94.6 +/- 0.6% vs. 56.0 +/- 3.0% (mol/mol)) while the yield from ferulate after 72 h was more than doubled (28.3 +/- 3.3% vs. 12.0 +/- 2.3% (mol/mol)). The effect of eliminating Crc was similar in cultures grown on acetate, with the yield from p coumarate just slightly higher in the Crc deletion strain after 24 h (47.7 +/- 0.6% vs. 40.7 +/- 3.6% (mol/mol)) and the yield from ferulate increased more than 60% after 72 h (16.9 +/- 1.4% vs. 10.3 +/- 0.1% (mol/mol)). These results are an example of the benefit that reducing carbon catabolite repression can have on conversion of complex feedstocks by microbial cell factories, a concept we posit could be broadly considered as a strategy in metabolic engineering for conversion of renewable feedstocks to value-added chemicals. PMID- 29188182 TI - A comprehensive evaluation of constraining amino acid biosynthesis in compartmented models for metabolic flux analysis. AB - Recent advances in the availability and applicability of genetic tools for non conventional yeasts have raised high hopes regarding the industrial applications of such yeasts; however, quantitative physiological data on these yeasts, including intracellular flux distributions, are scarce and have rarely aided in the development of novel yeast applications. The compartmentation of eukaryotic cells adds to model complexity. Model constraints are ideally based on biochemical evidence, which is rarely available for non-conventional yeast and eukaryotic cells. A small-scale model for 13C-based metabolic flux analysis of central yeast carbon metabolism was developed that is universally valid and does not depend on localization information regarding amino acid anabolism. The variable compartmental origin of traced metabolites is a feature that allows application of the model to yeasts with uncertain genomic and transcriptional backgrounds. The presented test case includes the baker's yeast Saccharomyces cerevisiae and the methylotrophic yeast Hansenula polymorpha. Highly similar flux solutions were computed using either a model with undefined pathway localization or a model with constraints based on curated (S. cerevisiae) or computationally predicted (H. polymorpha) localization information, while false solutions were found with incorrect localization constraints. These results indicate a potentially adverse effect of universally assuming Saccharomyces-like constraints on amino acid biosynthesis for non-conventional yeasts and verify the validity of neglecting compartmentation constraints using a small-scale metabolic model. The model was specifically designed to investigate the intracellular metabolism of wild-type yeasts under various growth conditions but is also expected to be useful for computing fluxes of other eukaryotic cells. PMID- 29188184 TI - UP Finder: A COBRA toolbox extension for identifying gene overexpression strategies for targeted overproduction. AB - Overexpression of key genes is a basic strategy for overproducing target products via metabolic engineering. Traditionally, identifying those key genes/pathways largely relies on the knowledge of biochemistry and bioinformatics. In this study, a modeling tool named UP Finder was developed to facilitate the rapid identification of gene overexpression strategies. It was based on the COBRA toolbox under MATLAB environment. All the key gene/pathway targets are identified in one click after simply loading a Systems Biology Markup Language model and specifying a metabolite as the targeted product. The outputs are also quantitatively ranked to show the preference for determining overexpression strategies in pathway design. Analysis examples for overproducing lycopene precursor in Escherichia coli and fatty acyl-ACP in the cyanobacterium Synechocystis sp. PCC 6803 by the UP Finder showed high degree of agreement with the reported key genes in the literatures. PMID- 29188183 TI - Isobutanol production in Synechocystis PCC 6803 using heterologous and endogenous alcohol dehydrogenases. AB - Isobutanol is a flammable compound that can be used as a biofuel due to its high energy density and suitable physical and chemical properties. In this study, we examined the capacity of engineered strains of Synechocystis PCC 6803 containing the alpha-ketoisovalerate decarboxylase from Lactococcus lactis and different heterologous and endogenous alcohol dehydrogenases (ADH) for isobutanol production. A strain expressing an introduced kivd without any additional copy of ADH produced 3 mg L-1 OD750-1 isobutanol in 6 days. After the cultures were supplemented with external addition of isobutyraldehyde, the substrate for ADH, 60.8 mg L-1 isobutanol was produced after 24 h when OD750 was 0.8. The in vivo activities of four different ADHs, two heterologous and two putative endogenous in Synechocystis, were examined and the Synechocystis endogenous ADH encoded by slr1192 showed the highest efficiency for isobutanol production. Furthermore, the strain overexpressing the isobutanol pathway on a self-replicating vector with the strong Ptrc promoter showed significantly higher gene expression and isobutanol production compared to the corresponding strains expressing the same operon introduced on the genome. Hence, this study demonstrates that Synechocystis endogenous AHDs have a high capacity for isobutanol production, and identifies kivd encoded alpha-ketoisovalerate decarboxylase as one of the likely bottlenecks for further isobutanol production.

AB - Modification of the Schizosaccharomyces pombe genome is often laborious, time consuming due to the lower efficiency of homologous recombination. Here, we constructed metabolically engineered S. pombe strains using a CRISPR-Cas9 system and also demonstrated D-lactic acid (D-LA) production from glucose and cellobiose. Genes encoding two separate pyruvate decarboxylases (PDCs), an L lactic acid dehydrogenase (L-LDH), and a minor alcohol dehydrogenase (SPBC337.11) were disrupted, thereby attenuating ethanol production. To increase the cellular supply of acetyl-CoA, an important metabolite for growth, we introduced genes encoding bacterial acetylating acetaldehyde dehydrogenase enzymes (Escherichia coli MhpF and EutE). D-LA production by the resulting strain was achieved by expressing a Lactobacillus plantarum gene encoding D-lactate dehydrogenase. The engineered strain efficiently consumed glucose and produced D-LA at 25.2 g/L from 35.5 g/L of consumed glucose with a yield of 0.71 g D-LA / g glucose. We further modified this strain by expressing beta-glucosidase by cell surface display; the resulting strain produced D-LA at 24.4 g/L from 30 g/L of cellobiose in minimal medium, with a yield of 0.68 g D-LA / g glucose. To our knowledge, this study represents the first report of a S. pombe strain that was metabolically engineered using a CRISPR-Cas9 system, and demonstrates the possibility of engineering S. pombe for the production of value-added chemicals.

PMID- 29188187 TI - Genome sequence and analysis of Escherichia coli production strain LS5218. AB - Escherichia coli strain LS5218 is a useful host for the production of fatty acid derived products, but the genetics underlying this utility have not been fully investigated. Here, we report the genome sequence of LS5218 and a list of large mutations and single nucleotide permutations (SNPs) relative to E. coli K-12 strain MG1655. We discuss how genetic differences may affect the physiological differences between LS5218 and MG1655. We find that LS5218 is more closely related to E. coli strain NCM3722 and suspect that small genetic differences between K-12 derived strains may have a significant impact on metabolic engineering efforts. PMID- 29188186 TI - YaliBricks, a versatile genetic toolkit for streamlined and rapid pathway engineering in Yarrowia lipolytica. AB - Effective metabolic engineering of microorganisms relies on balanced expression of both heterologous and endogenous genes to channel metabolic flux towards products of interest while achieving reasonable biomass buildup. To facilitate combinatorial pathway engineering and facile genetic operation, we engineered a set of modular cloning vectors compatible with BioBrick standards, called YaliBricks, to allow for rapid assembly of multigene pathways with customized genetic control elements (promoters, intronic sequences and terminators) in the oleaginous yeast Yarrowia lipolytica. We established a sensitive luciferase reporter and characterized a set of 12 native promoters to expand the oleaginous yeast genetic toolbox for transcriptional fine-tuning. We harnessed the intron alternative splicing mechanism and explored three unique gene configurations that allow us to encode genetic structural variations into metabolic function. We elucidated the role of how these genetic structural variations affect gene expression. To demonstrate the simplicity and effectiveness of streamlined genetic operations, we assembled the 12 kb five-gene violacein biosynthetic pathway in one week. We also expanded this set of vectors to accommodate self cleavage ribozymes and efficiently deliver guide RNA (gRNA) for targeted genome editing with a codon-optimized CRISPR-Cas9 nuclease. Taken together, the tools built in this study provide a standard procedure to streamline and accelerate metabolic pathway engineering and genetic circuits construction in Yarrowia lipolytica. PMID- 29188189 TI - Formation of supported lipid bilayers of charged E. coli lipids on modified gold by vesicle fusion. AB - We describe a simple way of fusing E. coli lipid vesicles onto a gold surface. Supported lipid bilayers on metal surfaces are interesting for several reasons: transducing a biological signal to an electric readout, using surface analytical tools such as Surface Plasmon Resonance (SPR), Infrared Reflection Absorption Spectroscopy, Neutron Reflectivity or Electrochemistry. The most widely used method to prepare supported lipid membranes is fusion of preexisting liposomes. It is quite efficient on hydrophilic surfaces such as glass, mica or SiO2, but vesicle fusion on metals and metal oxide surfaces (as gold, titanium oxide or indium tin oxide), remains a challenge, particularly for vesicles containing charged lipids, as is the case of bacterial lipids. We describe a simple method based on modifying the gold surface with a charged mercaptopropionic acid self assembled monolayer and liposomes partially solubilized with detergent. The formed bilayers were characterized using a Quartz Crystal Microbalance with dissipation (QCM-D) and Atomic Force Microscopy (AFM). Some advantages of this protocol are that the stability of the self-assembled monolayer allows for repeated use of the substrate after detergent removal of the bilayer and that the amount of detergent required for optimal fusion can be determined previously using the lipid-detergent solubility curve. PMID- 29188190 TI - Quality control of oceanographic in situ data from Argo floats using climatological convex hulls. AB - A new method of identifying anomalous oceanic temperature and salinity (T/S) data from Argo profiling floats is proposed. The proposed method uses World Ocean Database 2013 climatology to classify good against anomalous data by using convex hulls. An n-sided polygon (convex hull) with least area encompassing all the climatological points is constructed using Jarvis March algorithm. Subsequently Points In Polygon (PIP) principle implemented using ray casting algorithm is used to classify the T/S data as within or without acceptable bounds. It is observed that various types of anomalies associated with the oceanographic data viz., spikes, bias, sensor drifts etc can be identified using this method. Though demonstrated for Argo data it can be applied to any oceanographic data. *The patterns of variation of the parameter (temperature or salinity) corresponding to a particular depth, along the longitude or latitude can be used to build convex hulls.*This method can be effectively used for quality control by building Convex hulls for various observed depths corresponding to biogeochemical data which are sparsely observed.*This method has the advantage of treating the bulk of oceanographic in situ data in a single iteration which filters out anomalous data.

AB - Prostate cancer exhibits intra-tumoral heterogeneity that we hypothesize to be the leading confounding factor contributing to the underperformance of the current pre-treatment clinical-pathological and genomic assessment. These limitations impose an urgent need to develop better computational tools to identify men with low risk of prostate cancer versus others that may be at risk for developing metastatic cancer. The patient stratification will directly translate to patient treatments, wherein decisions regarding active surveillance or intensified therapy are made. Multiparametric MRI (mpMRI) provides the platform to investigate tumor heterogeneity by mapping the individual tumor habitats. We hypothesize that quantitative assessment (radiomics) of these habitats results in distinct combinations of descriptors that reveal regions with different physiologies and phenotypes. Radiogenomics, a discipline connecting tumor morphology described by radiomic and its genome described by the genomic data, has the potential to derive "radio phenotypes" that both correlate to and complement existing validated genomic risk stratification biomarkers. In this article we first describe the radiomic pipeline, tailored for analysis of prostate mpMRI, and in the process we introduce our particular implementations of radiomics modules. We also summarize the efforts in the radiomics field related to prostate cancer diagnosis and assessment of aggressiveness. Finally, we describe our results from radiogenomic analysis, based on mpMRI-Ultrasound (MRI US) biopsies and discuss the potential of future applications of this technique. The mpMRI radiomics data indicate that the platform would significantly improve the biopsy targeting of prostate habitats through better recognition of indolent versus aggressive disease, thereby facilitating a more personalized approach to prostate cancer management. The expectation to non-invasively identify habitats with high probability of housing aggressive cancers would result in directed biopsies that are more informative and actionable. Conversely, providing evidence for lack of disease would reduce the incidence of non-informative biopsies. In radiotherapy of prostate cancer, dose escalation has been shown to reduce biochemical failure. Dose escalation only to determinate prostate habitats has the potential to improve tumor control with less toxicity than when the entire prostate is dose escalated. PMID- 29188193 TI - The Use of Flow Cytometry in Myelodysplastic Syndromes: A Review. AB - Myelodysplastic syndromes (MDSs) are a heterogeneous group of hematopoietic stem cell diseases categorized by dysplasia in one or more hematopoietic cell lineages, as well as cytopenia and functional abnormalities in bone marrow cells. Several MDS classification methods have been proposed to categorize the disease and help professionals better plan in patients' treatment. The World Health Organization classification, released in 2008 and revised in 2016, is the currently and the most used classification method worldwide. Recent advances in MDS molecular biology and innovations in flow cytometry have enabled the development of new parameters for MDS diagnosis and classification. Several groups have published flow cytometry scores and guidelines useful for the diagnosis and/or prognosis of MDS, which are mostly based on detecting immunophenotypic abnormalities in granulocyte, monocyte, and lymphoid lineages. Here, we review the current literature and discuss the main parameters that should be analyzed by flow cytometry with the aim of refining MDS diagnosis and prognosis. Furthermore, we discuss the critical role of flow cytometry and molecular biology in MDS diagnosis and prognosis, as well as the current challenges and future perspectives involving these techniques. PMID- 29188196 TI - The treatment of low-grade septic non-unions. AB - Non-union (or pseudoarthrosis) is defined as a fracture that fails to consolidate after 6 months from the trauma. Current conservative treatments consist of biological (i.e. with calcium, Vitamin D) and mechanical stimulation. Moreover, surgical approaches include the use of endomidollar nail osteosynthesis, compression plates that are often associated with bone grafts. External fixation is a valid surgical alternative especially in case of septic non-unions. Indeed, compression-distraction osteosynthesis results in a significant improvement in bone vascularisation and exerts a powerful osteoinductive stimulus on the non union site. In this review, we will describe a cohort of patients affected by low grade septic non-unions and treated with external fixation. PMID- 29188194 TI - Beyond Paralogs: The Multiple Layers of Redundancy in Bacterial Pathogenesis. AB - Redundancy has been referred to as a state of no longer being needed or useful. Microbiologists often theorize that the only case of true redundancy in a haploid organism would be a recent gene duplication event, prior to divergence through selective pressure. However, a growing number of examples exist where an organism encodes two genes that appear to perform the same function. For example, many pathogens translocate multiple effector proteins into hosts. While disruption of individual effector genes does not result in a discernable phenotype, deleting genes in combination impairs pathogenesis: this has been described as redundancy. In many cases, this apparent redundancy could be due to limitations of laboratory models of pathogenesis that do not fully recapitulate the disease process. Alternatively, it is possible that the selective advantage achieved by this perceived redundancy is too subtle to be measured in the laboratory. Moreover, there are numerous possibilities for different types of redundancy. The most common and recognized form of redundancy is functional redundancy whereby two proteins have similar biochemical activities and substrate specificities allowing each one to compensate in the absence of the other. However, redundancy can also exist between seemingly unrelated proteins that manipulate the same or complementary host cell pathways. In this article, we outline 5 types of redundancy in pathogenesis: molecular, target, pathway, cellular process, and system redundancy that incorporate the biochemical activities, the host target specificities and the impact of effector function on the pathways and cellular process they modulate. For each type of redundancy, we provide examples from Legionella pathogenesis as this organism employs over 300 secreted virulence proteins and loss of individual proteins rarely impacts intracellular growth. We also discuss selective pressures that drive the maintenance of redundant mechanisms, the current methods used to resolve redundancy and features that distinguish between redundant and non-redundant virulence mechanisms. PMID- 29188195 TI - Comparative Genomic Analysis of Two Clonally Related Multidrug Resistant Mycobacterium tuberculosis by Single Molecule Real Time Sequencing. AB - Background: Multidrug-resistant tuberculosis (MDR-TB) is posing a major threat to global TB control. In this study, we focused on two consecutive MDR-TB isolated from the same patient before and after the initiation of anti-TB treatment. To better understand the genomic characteristics of MDR-TB, Single Molecule Real Time (SMRT) Sequencing and comparative genomic analyses was performed to identify mutations that contributed to the stepwise development of drug resistance and growth fitness in MDR-TB under in vivo challenge of anti-TB drugs. Result: Both pre-treatment and post-treatment strain demonstrated concordant phenotypic and genotypic susceptibility profiles toward rifampicin, pyrazinamide, streptomycin, fluoroquinolones, aminoglycosides, cycloserine, ethionamide, and para aminosalicylic acid. However, although both strains carried identical missense mutations at rpoB S531L, inhA C-15T, and embB M306V, MYCOTB Sensititre assay showed that the post-treatment strain had 16-, 8-, and 4-fold elevation in the minimum inhibitory concentrations (MICs) toward rifabutin, isoniazid, and ethambutol respectively. The results have indicated the presence of additional resistant-related mutations governing the stepwise development of MDR-TB. Further comparative genomic analyses have identified three additional polymorphisms between the clinical isolates. These include a single nucleotide deletion at nucleotide position 360 of rv0888 in pre-treatment strain, and a missense mutation at rv3303c (lpdA) V44I and a 6-bp inframe deletion at codon 67-68 in rv2071c (cobM) in the post-treatment strain. Multiple sequence alignment showed that these mutations were occurring at highly conserved regions among pathogenic mycobacteria. Using structural-based and sequence-based algorithms, we further predicted that the mutations potentially have deleterious effect on protein function. Conclusion: This is the first study that compared the full genomes of two clonally-related MDR-TB clinical isolates during the course of anti-TB treatment. Our work has demonstrated the robustness of SMRT Sequencing in identifying mutations among MDR-TB clinical isolates. Comparative genome analysis also suggested novel mutations at rv0888, lpdA, and cobM that might explain the difference in antibiotic resistance and growth pattern between the two MDR-TB strains. PMID- 29188198 TI - Evaluation of the changing landscape of prostate cancer diagnosis and management from 2005 to 2016. AB - Background: Approaches to prostate cancer (PCa) diagnosis and treatment have evolved significantly over past decades. There has been an increasing focus on minimizing overdiagnosis and overtreatment of clinically insignificant PCa. The objective of this study was to evaluate the changes in the diagnostic approach and initial treatment strategy that has evolved over time in an Australian urological private practice. Materials and methods: Men with newly diagnosed PCa were identified from the private practice electronic and paper medical records from 2005 to 2016 and data was consolidated into six groups of 2-year intervals. Diagnostic strategy was analyzed with particular reference to the use of multiparametric magnetic resonance imaging (mpMRI) scan and 68Ga-prostate specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) scans. National Comprehensive Cancer Network risk group stratification was correlated with initial treatment strategy and compared over time. Results: Chart review identified 839 men who had a mean age of 65.8 years. In 2011-2012, prebiopsy mpMRI scan was introduced. Its uptake correlated with a decrease in numbers of men diagnosed with low risk cancer (r = -0.80, P = 0.04) and an increase in numbers of men diagnosed with high-risk cancer (r = 0.90, P = 0.01). The use of 68Ga-PSMA PET/CT was associated with decreasing use of CT and bone scans performed. Open radical prostatectomy had a declining trend particularly when robotic surgery (robotic assisted radical prostatectomy (RARP)) was introduced. Pelvic lymph node dissections performed progressively decreased. An increased use of luteinizing hormone receptor hormone (LHRH) antagonists was seen in favor of LHRH agonists. Whilst use of high dose rate brachytherapy declined, there was an increased use of low dose rate brachytherapy. Conclusion: Prebiopsy mpMRI has been associated with an increased proportion of newly diagnosed men having clinically significant PCa. Over time, 68Ga-PSMA PET/CT scans, robotic assisted radical prostatectomy (RARP) and LHRH antagonists have increased in use, whilst CT and bone scans, and pelvic lymph node dissections have decreased. PMID- 29188199 TI - Effects of 25- and 30-degree Trendelenburg positions on intraocular pressure changes during robot-assisted radical prostatectomy. AB - Background: The objective of this study was to assess the effects of 25-degree and 30-degree Trendelenburg positions on intraocular pressure (IOP) changes during robot-assisted radical prostatectomy (RARP). Materials and methods: This prospective study involved a total of 30 consecutive patients undergoing RARP. All participants were randomly divided into two groups: Trendelenburg position with the head down at 25 degrees or 30 degrees. In addition to representative operative outcomes, IOP was measured at six discrete time points; Time 1 (T1): before induction of general anesthesia, patients in a horizontal supine position; T2: after induction of general anesthesia, patients in a horizontal supine position; T3: 1 hour after adopting the Trendelenburg position; T4: 2 hours after adopting the Trendelenburg position; T5: after pneumoperitoneum resolution in the Trendelenburg position; T6: anesthetized before awakening in a supine position. Results: The total and console operative times, estimated blood loss, and intravenous fluid intake during RARP did not significantly differ between the two groups. While the IOP values measured at the same time points were similar between the two groups, the 25-degree Trendelenburg position significantly attenuated the IOP change from T1 to T3, T4, and T5 compared with those at 30 degrees. Conclusions: These findings suggest that RARP in the 25-degree Trendelenburg position may reduce the risks of position-related ophthalmic complications without increasing the difficulty of the surgical procedure. PMID- 29188197 TI - 68Ga-prostate-specific membrane antigen-positron emission tomography/computed tomography in advanced prostate cancer: Current state and future trends. AB - The early and accurate detection of prostate cancer is important to ensure timely management and appropriate individualized treatment. Currently, conventional imaging has limitations particularly in the early detection of metastases and at prostate-specific antigen (PSA) levels < 2.0 ng/mL. Furthermore, disease management such as salvage radiotherapy is best at low PSA levels. Thus, it is critical to capture the disease in the oligometastatic stage as disease progression and commencement of systemic therapies can be delayed by metastasis directed therapy. Prostate-specific membrane antigen (PSMA) is overexpressed in prostatic cancer cells. Novel imaging modalities using radiolabeled tracers with PSMA such as 68Ga-PSMA-positron emission tomography (PET)/computed tomography (CT) have shown promising results. We review the literature regarding 68Ga-PSMA PET/CT in the setting of primary prostate cancer and biochemical recurrence. At present, the best utilization of 68Ga-PSMA-PET/CT appears to be in biochemical recurrence. 68Ga-PSMA-PET/CT has high diagnostic accuracy for lymph node metastases and has been shown to have superior detection rates to conventional imaging, especially at low PSA levels. The exact role of 68Ga-PSMA-PET/CT in primary prostate cancer is not yet entirely clear. It has an improved detection rate for smaller lesions and may be able to identify nodal or distant metastatic disease at an earlier stage. While still experimental, there may also be value in combining 68Ga-PSMA-PET to multiparametric magnetic resonance imaging for staging of intraprostatic disease. To date, 68Ga-PSMA-PET/CT has been shown to have considerable clinical value and to impact treatment selection for patients with prostate cancer. Still in its infancy, the results of future clinical trials will be excitedly awaited. PMID- 29188200 TI - Management and outcomes of Gleason six prostate cancer detected on needle biopsy: A single-surgeon experience over 6 years. AB - Objective: To assess the management and oncological outcomes in men diagnosed with Gleason score (GS) 6 prostate cancer on needle biopsy in a regional centre, as compared with published international data. Materials and methods: A retrospective analysis was conducted of patients who were diagnosed with GS 6 prostate cancer via transrectal ultrasound-guided or transperineal biopsy between June 2009 and September 2015 under the care of a single surgeon. Data were obtained from a prospectively collected database. Results: A total of 166 patients were diagnosed with GS 6 prostate cancer. The mean age was 61 (range 46 79) years, with mean prostate-specific antigen of 6.7 (0.91-26.8) ng/mL at diagnosis. Of 166 patients, 117 (70.5%) patients were enrolled into the active surveillance program with 82 (70%) meeting Prostate Cancer Research International Active Surveillance (PRIAS) criteria, 44 patients underwent immediate definitive treatment (88.6% radical prostatectomy and 9.1% radiotherapy) and five watchful waiting. With a median follow-up of 1.8 years, 37 (31.6%) patients on AS had definitive treatment [30 cases (81%) were attributable to disease progression, 4 cases (10.8%) to an abnormal magnetic resonance imaging result and 3 cases (8.1%) for patient preference]. In the 35 patients who underwent radical prostatectomy immediately after diagnosis, the GS was >=7 in 29 cases (82.9%), and the final pathology was pT3a in 16 (51.6%) and pT3b in one (2.9%). In patients who underwent radical prostatectomy after being on AS, the proportion of GS >=7 prostate cancer was 29/32 (90.6%), with pT3a in six (18.8%) and pT3b in three (9.4%) cases. Overall, 23.5% of patients had a multiparametric magnetic resonance imaging scan. Conclusion: This single-surgeon cohort of GS 6 prostate cancer patients demonstrates a high proportion of cases managed with active surveillance, with comparable rates to international literature. The majority of cases who underwent immediate definitive treatment had significant disease, indicating that patients are being appropriately selected for active surveillance. PMID- 29188202 TI - Seminal plasma enables selection and monitoring of active surveillance candidates using nuclear magnetic resonance-based metabolomics: A preliminary investigation. AB - Background: Diagnosis and monitoring of localized prostate cancer requires discovery and validation of noninvasive biomarkers. Nuclear magnetic resonance (NMR)-based metabolomics of seminal plasma reportedly improves diagnostic accuracy, but requires validation in a high-risk clinical cohort. Materials and methods: Seminal plasma samples of 151 men being investigated for prostate cancer were analyzed with 1H-NMR spectroscopy. After adjustment for buffer (add-to subtract) and endogenous enzyme influence on metabolites, metabolite profiling was performed with multivariate statistical analysis (principal components analysis, partial least squares) and targeted quantitation. Results: Seminal plasma metabolites best predicted low- and intermediate-risk prostate cancer with differences observed between these groups and benign samples. Lipids/lipoproteins dominated spectra of high grade samples with less metabolite contributions. Overall prostate cancer prediction using previously described metabolites was not validated. Conclusion: Metabolomics of seminal plasma in vitro may assist urologists with diagnosis and monitoring of either low or intermediate grade prostate cancer. Less clinical benefit may be observed for high-risk patients. Further investigation in active surveillance cohorts, and/or in combination with in vivo magnetic resonance spectroscopic imaging may further optimize localized prostate cancer outcomes. PMID- 29188201 TI - Significant prognostic difference between Grade Group 4 and 5 in the 2014 International Society of Urological Pathology Grading System for High Grade Prostate Cancer with Bone Metastasis. AB - Background: To investigate prognostic difference between Gleason Score (GS) 8 and 9-10, as the 2014 International Society of Urological Pathology Gleason Grading Systems proposed, in patients with prostate cancer (PCa) with bone metastasis. Materials and methods: We retrospectively reviewed data on 106 patients with GS 8 10 between 2006 and 2016. All patients received androgen deprivation therapy immediately. We validated biochemical recurrence, PCa-specific survival, and overall survival, and analyzed the predictive value for overall survival. Results: Patients with GS 9-10 had significantly lower PCa-specific survival (50.5% vs. 83.4%, P = 0.01) and overall survival (38.8% vs. 66.3%, P = 0.04) at 5 years than those with GS 8, while biochemical recurrence rate was not significantly different (P = 0.26). Furthermore, these significant differences between GS 8 and 9-10 were also observed among high-risk groups proposed in Japan Cancer of the Prostate Risk Assessment Stratification (prostate cancer-specific survival: P = 0.03, overall survival: P = 0.04, respectively). Pathological GS 9 10 was an independent prognostic factor for overall survival (hazard ratio = 1.97, P = 0.04) in multivariable cox proportional hazard regression analysis. Among patients with GS 9-10, albumin level was an only prognostic factor for overall survival (hazard ratio = 0.33, P < 0.01). Conclusion: Pathological GS 9 10 predicts significantly worse outcomes than GS 8 in Japanese PCa patients with bone metastasis. Our data indicated clinical significance of discriminating the 2014 International Society of Urological Pathology Gleason Grading Group 4 and 5 among high-risk PCa patients with bone metastasis. PMID- 29188204 TI - Greetings from the New Editor-in-Chief. PMID- 29188203 TI - Comparison of Visual Prostate Symptom Score and International Prostate Symptom Score in the evaluation of men with benign prostatic hyperplasia: A prospective study from an Indian population. AB - Background: Lower urinary tract symptoms (LUTSs) due to benign prostatic hyperplasia (BPH) are common conditions in middle-age or older men. The International Prostate Symptom Score (IPSS) is a useful and validated questionnaire to evaluate LUTS secondary to BPH. Van der Walt et al have developed an alternative questionnaire named the Visual Prostate Symptom Score (VPSS) questionnaire. This study aimed to evaluate the relationship between the VPSS and IPSS in the evaluation of men with LUTSs due to BPH in an Indian population. Materials and methods: This was a prospectively designed study conducted at Sri Sathya Sai Institute of Higher Medical Sciences, Prashanthigram (Anantapur, Andhra Pradesh, India). A total of 121 patients who presented to the urology outpatient department with LUTS due to BPH were enrolled in the study. Patients were followed up at 1-month and 3-month intervals. All patients were given both questionnaires. The correlation test was used to assess the correlation between two symptom scores and various parameters. Observations with a P value < 0.05 were considered statistically significant. Results: There was a statistically significant difference in the number of patients requiring assistance to fill the questionnaires according to their education level. There was a positive correlation between IPSS total score and VPSS total score (r = 0.7235; P < 0.0001), VPSS total score and VPSS quality of life (Qol; r = 0.70753; p < 0.0001), IPSS total versus IPSS Qol (r = 0.65583; P < 0.0001), and IPSS Qol versus VPSS Qol (r = 0.84093; P < 0.0001). A negative correlation was observed between total VPSS with Qmax, total IPSS with Qmax, IPSS total versus Qavg (r = 0.479; P < 0.0001), and VPSS total versus Qavg (r = -0.5; P < 0.0001). All VPSS questions showed statistically significant correlation with the corresponding IPSS questions. Conclusion: There is a statistically significant correlation between the VPSS and IPSS and it can be completed by a greater number of patients without assistance. PMID- 29188205 TI - Recurred Intracranial Meningioma: A Retrospective Analysis for Treatment Outcome and Prognostic Factor. AB - Background: In this study, we aimed to compare repeated resection and radiation treatment, such as Gamma knife radiosurgery (GKRS) or conventional radiotherapy (RT), and investigate the factors influencing treatment outcome, including overall survival (OS), progression-free survival (PFS), and complication rates. Methods: We retrospectively reviewed 67 cases of recurred intracranial meningiomas (repeated resection: 36 cases, radiation treatment: 31 cases) with 56 months of the median follow-up duration (range, 13-294 months). Results: The incidence of death rate was 29.9% over follow-up period after treatment for recurred meningiomas (20/67). As independent predictable factors for OS, benign pathology [hazard ratio (HR) 0.132, 95% confidence interval (CI) 0.048-0.362, p<0.001] and tumor size <3 cm (HR 0.167, 95% CI 0.061-0.452, p<0.001) were significantly associated with a longer OS. The incidence of progression rate was 23.9% (16/67). Only treatment modality was important for PFS as an independent predictable factor (GKRS/RT vs. open resection; HR 0.117, 95% CI 0.027-0.518, p<0.005). The complication rate was 14.9% in our study (10/67). Larger tumor size (>=3 cm, HR 0.060, 95% CI 0.007-0.509, p=0.010) was significant as an independent prognostic factor for development of complications. Although treatment modality was not included for multivariate analysis, it should be considered as a predictable factor for complications (p=0.001 in univariate analysis). Conclusion: The role of repeated resection is questionable for recurred intracranial meningiomas, considering high progression and complication rates. Frequent and regular imaging follow-up is required to detect recurred tumor sized as small as possible, and radiation treatment can be a preferred treatment. PMID- 29188207 TI - Ependymomas: Prognostic Factors and Outcome Analysis in a Retrospective Series of 33 Patients. AB - Background: The purpose of this study was to evaluate the prognostic factors and outcomes in patients with ependymoma to management plans. Methods: Between 1997 and 2013, 33 patients with 25 ependymomas (WHO grade II) and eight anaplastic ependymomas (WHO grade III) were pathologically diagnosed. Six were pediatric patients (mean age, 6.15 years; range, 1.3-11 years), while 27 were adults (mean age, 47.5 years; range, 19-70 years). Of those, there were 12 adult patients with totally resected ependymomas without anaplastic pathology and adjuvant treatment. Prognostic factors were assessed in ependymoma patients. Prognostic factors were studied using Kaplan-Meier estimates in subgroups. Results: For six pediatric patients, the progression-free survival (PFS) was 43.7+/-13.5 months, and the overall survival (OS) was 58.1+/-13.7 months. For 27 adult patients, the PFS was 125.6+/-14.3 months, and the OS was 151.2+/-12.5 months. Age demonstrated a statistically significant effect on PFS (p=0.03) and OS (p=0.03). In adult ependymomas, the extent of tumor removal significantly affected PFS (p=0.03) and trended towards an effect on OS (p=0.06). Out of 12 patients with totally resected ependymomas without anaplastic pathology and adjuvant treatment, one patient showed tumor recurrence during follow-up (mean, 93.5 months; range, 27.9 162.7 months). Conclusion: Adult patients with ependymomas were found to have better survival rates compared to pediatric patients. We suggest that totally resected adult ependymomas without anaplastic pathology could be observed without any adjuvant treatment, regardless of the tumor location. PMID- 29188208 TI - The Clinical Outcome of Hydroxyurea Chemotherapy after Incomplete Resection of Atypical Meningiomas. AB - Background: The aim of this study is to investigate the clinical results of adjuvant chemotherapy with hydroxyurea and to compare those with the results of postoperative radiotherapy after incomplete resection of atypical meningiomas (ATMNGs). Methods: We retrospectively reviewed the medical records of 84 patients with ATMNGs diagnosed in the period from January 2000 to December 2014. Clinical data included patient sex and age at the time of surgery, presenting symptoms at diagnosis, location and size of tumor, extent of surgery, use of postoperative radiotherapy or hydroxyurea chemotherapy, duration of follow-up, and progression. In terms of the extent of surgical resection, incomplete resection was defined as Simpson grade II-V. Results: Among the 85 patients, 55 (65.5%) patients underwent incomplete resection; 24 (43.6%) were treated with adjuvant hydroxyurea (group A), and 20 (36.4%) with postoperative radiotherapy (group B), and 11 (20.0%) underwent conservative treatment after surgery (group C). Twenty-five (45.5%) patients experienced the progression of tumors during the follow-up period (mean 47.7 months, range 12.4-132.1 months); 8 of 24 (33.3%) patients in group A, 7 of 20 (35.0%) patients in group B, and 10 of 11 (90.9%) patients in group C. The mean progression-free survival (PFS) was 30.9 months (range 6.4-62.3 months); 46.2 months in group A, 40.4 months in group B, and 11.9 months in group C (p=0.041). Multivariate analysis showed that Simpson grade (p=0.040), adjuvant treatment after surgery (p<0.001), increased Ki67 (p=0.017), mitotic index (p=0.034), and overexpression of p53 (p=0.026) predicted longer PFS. Conclusion: This investigation suggested that adjuvant treatment after incomplete resection of ATMNGs are associated with longer PFS than conservative treatment, and that there is no difference of PFS between hydroxyurea chemotherapy and radiotherapy after surgery. Therefore, hydroxyurea chemotherapy can be considered as another adjuvant tool for the ATMNGs if the postoperative adjuvant radiotherapy cannot be applicable. PMID- 29188209 TI - Outcomes in 20 Gynecologic Cancer Patient with Brain Metastasis: A Single Institution Retrospective Study. AB - Background: The incidence of brain metastasis (BM) in gynecologic cancers has risen recently, due to prolonged survival times and an early diagnosis. We analyzed treatment outcomes of patients with BM from gynecologic cancers. Methods: Among 951 patients with BM who were treated in neurosurgical department from July 2003 to February 2016, a total of 20 (2%) patients were from gynecologic cancers. The patients' clinical characteristics were collected by using medical records. There were 14 (66.7%) ovarian cancers, 4 (19.0%) uterine cancers, and 2 (9.5%) cervical cancers. As a primary treatment modality, 11 patients were treated with Gamma Knife surgery (GKS), 6 with surgical resection followed by whole brain radiation therapy (WBRT), and 3 with WBRT only. Overall and progression-free survival according to the primary origin and the primary treatment were analyzed. Results: Median overall survival time was 28 months, and progression-free survival was 15 months. In patients with ovarian cancer, median overall survival did not reach during the follow-up periods and progression-free survival time was 15 months. Median overall survival time in patients who received GKS as the primary treatment was 17 months and that in patients who underwent surgical resection followed by WBRT was 37.3 months (p=0.16). The median value of progression-free survival time in patients who received GKS as the primary treatment was 12 months and that in patients who underwent surgical resection with WBRT was 42 months (p=0.042). Median follow up period of over all patients was 13 months. Conclusion: BM from gynecologic cancer is rare (2%), but our findings suggest that the prognosis might not always be poor. In our small series, surgical resection with WBRT was a treatment modality significantly associated with a longer progression-free survival. Additional studies with more cases and multi-institutional cooperation are needed to determine which treatment modality leads to better outcomes. PMID- 29188206 TI - Genomic and Molecular Characterization of Brain Tumors in Asian and Non-Asian Patients of Los Angeles: A Single Institution Analysis. AB - Background: Worldwide, approximately 2% of new cancers are of the brain. Five year survival rates among brain cancer patients have been reported as a little over a third. Differences in clinical outcomes between brain tumor patients of different races remain poorly understood. Methods: A retrospective chart review was performed on brain tumor resection patients>=18 years old. Demographics, treatment variables, and survival outcomes were collected. Primary outcomes were length of stay, recurrence rate, progression-free survival (PFS), and overall survival (OS). Results: A total of 452 patients were included in analysis. Females and males had nearly a 1:1 ratio (n=242 and n=220, respectively). Mean age was 54.8 years (SD: 14.5 range: 18-90). Females composed 69% (n=48) of Asian patients; males constituted 31% (n=22). Mean age of the Asian patients was 55.9 years (SD: 14.6 range: 26-89). Asian-only cohort tumor pathologies included glioblastoma (GBM) (n=14), high-grade glioma (n=7), low-grade glioma (n=4), meningioma (n=38), and metastases (n=7). Of the 185 meningioma patients, non Asian patients comprised 79% of the group (n=146). Of the 65 GBM patients in total, non-Asian patients made up 89% of the GBM cohort (n=58). There were no statistically significant differences between these groups of both cohorts in recurrence (p=0.1580 and p=0.6294, respectively), PFS (p=0.9662 and p=0.4048, respectively), or OS (p=0.3711 and p=0.8183, respectively). Conclusion: Studies evaluating the survival between patients of different racial backgrounds against several tumor varieties are rare. Patients of certain racial backgrounds may need additional consideration when being attended to despite the same mutational composition as their counterparts. Repeated studies using national databases may yield more conclusive results. PMID- 29188210 TI - Pituitary Ependymoma, 10-Year Follow-Up after Partial Resection and Radiation Therapy. AB - Ependymoma usually arises within the ventricles and central canal of the spinal cord. These tumors, found in the sellar region, are extremely rare. We report a case of pituitary ependymoma followed up over 10 years. A 59-year-old male patient presented with fatigue, general weakness, erectile dysfunction, and loss of body hair, including pubic hair. Brain magnetic resonance imaging (MRI) revealed a 3.3*3.5*2.3-cm sellar and suprasellar snowman-shaped enhancing mass. The tumor was partially resected via the trans-sphenoidal approach followed by postoperative radiation therapy. The pathologic confirmation was pituitary ependymoma. At the 10-year follow up, MRI revealed no evidence of tumor progression. With lack of knowledge about pituitary ependymoma, our case is the only case in which the disease has been well controlled over a long period of time without tumor progression. PMID- 29188211 TI - Response of Leptomeningeal Dissemination of Anaplastic Glioma to Temozolomide: Experience of Two Cases. AB - The incidence of leptomeningeal dissemination (LMD) of anaplastic glioma has been increasing. LMD can be observed at the time of initial presentation or the time of recurrence. As a result of both rarity and unusual presentation, a standard therapy has not yet been suggested. In contrast to leptomeningeal carcinomatosis for systemic solid cancers, a relatively prolonged survival is observed in some patients with LMD of anaplastic gliomas. Treatment modalities include whole craniospinal irradiation, intra-cerebrospinal fluid (CSF) chemotherapy, and systemic chemotherapy. In some cases, response to temozolomide (TMZ), with or without combined radiation has been reported. Here, we report two cases of LMD of an anaplastic glioma. In one case LMD presented at the time of diagnosis, and in the other at the time of recurrence after radiation. CSF cytology was positive in both cases, and persisted in spite of intrathecal methotrexate chemotherapy. Later, TMZ was prescribed for progressing brain parenchymal lesions, and both radiological and cytological responses were obtained after oral TMZ treatment. PMID- 29188212 TI - Supratentorial Pilocytic Astrocytoma Mimicking Convexity Meningioma with Early Anaplastic Transformation: A Case Report. AB - Meningiomas and pilocytic astrocytomas are benign intracranial tumors. Pilocytic astrocytomas arises frequently at the posterior fossa in childhood. Meningiomas have several image findings, such as a dural tail sign, bony erosion, and sunburst appearance on angiography. However, pilocytic astrocytomas with these findings have been rarely reported. In this report, we describe a mass with typical image findings of a meningioma, but diagnosed as a supratentorial pilocytic astrocytoma with early anaplastic transformation. PMID- 29188213 TI - Pituicytoma with Significant Tumor Vascularity Mimicking Pituitary Macroadenoma. AB - A 19-year-old man presented with bitemporal hemianopsia and was found to have a large sellar and suprasellar tumor, resembling a pituitary macroadenoma. Emergency transsphenoidal approach was attempted because of rapid visual deterioration with headache. However, the approach was complicated and stopped by uncontrolled hemorrhage from the tumor. After conventional cerebral angiography and recognition of an unusual pathology, transcranial approach was achieved to prevent permanent visual loss. The final pathological diagnosis was pituicytoma with epithelioid features. Pituicytoma is a rare low-grade tumor (WHO Grade I) of pituicytes involving the sellar and suprasellar region, and originating from special glial cells of the neurohypophysis. Because of the high vascularity, the firm consistency, and invasion to surrounding neurovascular structures, a pituicytoma should be included in the differential diagnosis of a mass in the sellar and suprasellar area if the tumor shows high enhancement with vascular components. We report a case of rare pituicytoma mimicking a pituitary macroadenoma with massive hemorrhage to disturb surgery. PMID- 29188214 TI - Subfrontal Schwannoma Extended Broadly to Nasal Cavity Treated by Gamma Knife Radiosurgery Following Surgical Excision: A Case Report. AB - Subfrontal schwannomas are rarely reported. They are usually found only in the subfrontal area, but some extend to the nasal cavity. In these cases, prevention of postoperative cerebrospinal fluid (CSF) leakage through thinned or eroded anterior skull base is important. A 51-year-old female with anosmia and mild nausea was diagnosed as subfrontal extraaxial mass with nasal cavity extension. This mass was initially thought to be an olfactory groove meningioma. We performed a bifrontal craniotomy for surgical excision. We did not totally remove the tumor, as we wanted to prevent a skull base defect. The histopathological diagnosis was a schwannoma. There was no postoperative complication such as CSF leakage. The residual tumor was treated with gamma knife radiosurgery. The nasal cavity mass has not grown as of five years after radiosurgery. PMID- 29188216 TI - Extra-Axial and Clear Cell Type Ependymoma, Mimicking a Convexity Meningioma. AB - A 33-year-old woman presented with tingling and paresthesia on left extremity for 2 months. Magnetic resonance imaging revealed that the tumor was iso- and hypo intensity on T1-weighted image, mixed iso- and high-signal intensity on T2 weighted images and heterogeneously enhanced with rim enhancement. Neither arachnoid cleft nor dural tail was certain but mass was located extra-axially so meningioma was suspected. During operation, tumor wasn't attached to dura at all but arachnoid attachment was seen. Pathologically, clear cell type ependymoma was confirmed. Details of diagnosis and treatment of this tumor is described. PMID- 29188215 TI - Astroblastoma in a Young Female Patient: A Case Report and Literature Review of Clinicopathological, Radiological and Prognostic Characteristics and Current Treatment Strategies. AB - Astroblastoma is an uncommon glial tumor with predominant manifestation in the young age. Herein, we report a case of 18-year-old astroblastoma female patient who presented with history of two months headache. Magnetic resonance imaging (MRI) of the brain demonstrated well circumscribed, intra-axial abnormal signal intensity lesion (size=5*4 cm2) in the right parieto-occipital region of the brain. The patient underwent complete surgical resection of the gross tumor, as confirmed by an early post-surgical MRI (i.e., within 24 hours of surgery). Histopathological examination revealed neoplastic lesion exhibiting perivascular pseudo-rosettes with centrally hyalinized blood vessel and focal nuclear pleomorphism. Immunohistochemistry staining illustrated reactivity for glial fibrillary acidic protein and integrase interactor 1 (INI-1). These features rendered the diagnosis of astroblastoma. A comprehensive review of the current literature to summarize the clinicopathological and radiological characteristics, prognostic factors and current treatment strategies of astroblastomas is also presented. Our study would expand the pool of this uncommon tumor towards its better understanding and optimal treatment. PMID- 29188217 TI - Prediction of the Thermal Conductivity of Refrigerants by Computational Methods and Artificial Neural Network. AB - Background: The thermal conductivity of fluids can be calculated by several computational methods. However, these methods are reliable only at the confined levels of density, and there is no specific computational method for calculating thermal conductivity in the wide ranges of density. Methods: In this paper, two methods, an Artificial Neural Network (ANN) approach and a computational method established upon the Rainwater-Friend theory, were used to predict the value of thermal conductivity in all ranges of density. The thermal conductivity of six refrigerants, R12, R14, R32, R115, R143, and R152 was predicted by these methods and the effectiveness of models was specified and compared. Results: The results show that the computational method is a usable method for predicting thermal conductivity at low levels of density. However, the efficiency of this model is considerably reduced in the mid-range of density. It means that this model cannot be used at density levels which are higher than 6. On the other hand, the ANN approach is a reliable method for thermal conductivity prediction in all ranges of density. The best accuracy of ANN is achieved when the number of units is increased in the hidden layer. Conclusion: The results of the computational method indicate that the regular dependence between thermal conductivity and density at higher densities is eliminated. It can develop a nonlinear problem. Therefore, analytical approaches are not able to predict thermal conductivity in wide ranges of density. Instead, a nonlinear approach such as, ANN is a valuable method for this purpose. PMID- 29188218 TI - Neuropsychological Correlates of Pre-Frailty in Neurocognitive Disorders: A Possible Role for Metacognitive Dysfunction and Mood Changes. AB - Background: Recent studies have suggested that cognitive functions in patients with neurocognitive disorders have a significant role in the pathogenic mechanisms of frailty. Although pre-frailty is considered an intermediate, preclinical state, epidemiological research has begun to dislodge cognition and frailty into their specific subcomponents to understand the relationship among them. We aim to analyse the possible association between pre-frailty and neuropsychological variables to outline which factors can contribute to minor and major neurocognitive disorders. Methods: 60 subjects complaining of different cognitive deficits underwent a deep-in-wide frailty and neuropsychological assessment. We conducted three multiple linear regression analyses adjusted for a combination of demographic measures and involving several neuropsychological behavioural parameters selected by the literature on physical frailty. Results: We found a significant association between frailty-as measured by the multidimensional prognostic index (MPI)-and action monitoring and monetary gain (cognitive domain), depression and disinhibition (behavioural domain). Moreover, an association between MPI and impaired awareness for instrumental activities disabilities exists. Conclusion: We propose a novel framework for understanding frailty associated with metacognitive-executive dysfunction. PMID- 29188220 TI - Evaluation of measurement tools for tobacco product displays: is there an app for that? AB - Tobacco product displays are a pervasive presence in convenience stores, supermarkets, pharmacies, and other retailers nationwide. The influence that tobacco product displays have on purchases and tobacco product initiation, particularly on young people and other vulnerable populations, is well known. An objective measurement tool that is valid, reliable, and feasible to use is needed to assess product displays in the retail setting. This study reports on the relative accuracy of various tools that measure area and/or distance in photos and thus could be applied to product displays. We compare results of repeated trials using five tools. Three tools are smartphone apps that measure objects in photos taken on the device; these are narrowed down from a list of 284 candidate apps. Another tool uses photos taken with any device and calculates relative area via a built-in function in the Microsoft Office Suite. The fifth uses photos taken with the Narrative Clip, a "life-logging" wearable camera. To evaluate validity and reliability, we assess each instrument's measurements and calculate intra-class correlation coefficients. Mean differences between observed measurements (via tape measure) and those from the five tools range from just over one square foot to just over two square feet. Most instruments produce reliable estimates though some are sensitive to the size of the display. Results of this study indicate need for future research to test innovative measurement tools. This paper also solicits further discussion on how best to transform anecdotal knowledge of product displays as targeted and disproportionate marketing tactics into a scientific evidence base for public policy change. PMID- 29188221 TI - The influence of political candidates' facial appearance on older and younger adults' voting choices and actual electoral success. AB - Younger adults (YA) judgments of political candidates' competence from facial appearance accurately predict electoral success. Whether this is true for older adults (OA) has not been investigated despite the fact that OA are more likely to vote than YA and may respond differently to particular facial qualities. We examined whether OA and YA ratings of competence, trustworthiness, attractiveness, and babyfaceness of opposing candidates in US Senate elections independently predicted their own vote choices and actual election outcomes. OA and YA ratings of attractiveness, competence, and trustworthiness positively predicted their choices, but the effect of competence was weaker for OA. Babyfaceness negatively predicted OA, but not YA, choices. OA and YA competence ratings equally predicted the actual election winners, while OA, but not YA, attractiveness ratings did so. Trustworthy and babyface ratings did not predict actual winners. These findings have implications for understanding age differences in candidate preferences and the prediction of election outcomes. PMID- 29188219 TI - A Systematic Review of the Role of Robotics in Plastic and Reconstructive Surgery From Inception to the Future. AB - Background: The use of robots in surgery has become commonplace in many specialties. In this systematic review, we report on the current uses of robotics in plastic and reconstructive surgery and looks to future roles for robotics in this arena. Methods: A systematic literature search of Medline, EMBASE, and Scopus was performed using appropriate search terms in order to identify all applications of robot-assistance in plastic and reconstructive surgery. All articles were reviewed by two authors and a qualitative synthesis performed of those articles that met the inclusion criteria. The systematic review and results were conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta Analysis (PRISMA) guidelines. Results: A total of 7,904 articles were identified for title and abstract review. Sixty-eight studies met the inclusion criteria. Robotic assistance in plastic and reconstructive surgery is still in its infancy, with areas such as trans-oral robotic surgery and microvascular procedures the dominant areas of interest currently. A number of benefits have been shown over conventional open surgery, such as improved access and greater dexterity; however, these must be balanced against disadvantages such as the lack of haptic feedback and cost implications. Conclusion: The feasibility of robotic plastic surgery has been demonstrated in several specific indications. As technology, knowledge, and skills in this area improve, these techniques have the potential to contribute positively to patient and provider experience and outcomes. PMID- 29188223 TI - Dataset on the cost estimation for spent filter backwash water (SFBW) treatment. AB - The dataset presented in this article are related to the research article entitled "Hybrid coagulation-UF processes for spent filter backwash water treatment: a comparison studies for PAFCl and FeCl3 as a pre-treatment" (Ebrahimi et al., 2017) [1]. This article reports the cost estimation for treating produced spent filter backwash water (SFBW) during water treatment in Isfahan- Iran by various methods including primary sedimentation, coagulation & flocculation, second clarification, ultra filtration (UF) and recirculation of settled SFBW to water treatment plant (WTP) entrance. Coagulation conducted by PAFCl and FeCl3 as pre polymerized and traditional coagulants. Cost estimation showed that contrary to expectations, the recirculation of settled SFBW to WTP entrance is more expensive than other method and it costs about $ 37,814,817.6. Versus the cheapest option related to separate primary sedimentation, coagulation & flocculation in WTP. This option cost about $ 4,757,200 and $ 950,213 when FeCl3 and PAFCl used as coagulant, respectively. PMID- 29188222 TI - Effects of 3-year denosumab treatment on hip structure in Japanese postmenopausal women and men with osteoporosis. AB - Denosumab, a human monoclonal antibody against RANK ligand, is shown to have strong anti-fracture effects in Japanese osteoporosis patients. However, there have been no data showing actions on Japanese bone architecture. Here we show that denosumab continuously improves several geometrical parameters calculated by hip structural analysis for 3 years. Compared to placebo, denosumab significantly increased bone mineral density, cortical thickness and cross sectional area in all of the three analyzed areas: the narrow neck, intertrochanter and femoral shaft. The subsequent derived mechanical parameters, cross-sectional moment of inertia, section modulus and buckling ratio, were also improved by denosumab. In addition, the improvement of these parameters was also observed in the patients that had switched from placebo to denosumab treatment. The present study suggests the structural evidence explaining the strong anti-fracture efficacy of denosumab and its significant effects on cortical bone in Japanese.

PMID- 29188226 TI - Data on RNA-seq analysis of Garcinia mangostana L. seed development. AB - Mangosteen (Garcinia mangostana L.) has exceptional potential for commercial and pharmaceutical applications due to its delicious fruit and medicinal properties. Nevertheless, the molecular mechanism of mangosteen seed development is poorly understood. In this study, we performed transcriptomic analysis of four seed developmental stages; eight, ten, twelve and fourteen weeks after anthesis. Illumina HiSeqTM 4000 sequencer was used to generate raw data of approximately 68 Gb in size. From 451,495,326 raw reads, 406,143,756 clean reads were obtained. The raw data were uploaded to SRA database and the BioProject ID is PRJNA395504. These data provide the basis for further exploration and understanding of the molecular mechanism in mangosteen seed development.

PMID- 29188230 TI - Primers and copper responsive promoter design and data of real-time RT-PCR assay in filamentous fungus Trichoderma reesei. AB - This data article contains data related to the research article entitled "Copper mediated on-off control of gene expression in filamentous fungus Trichoderma reesei" (Wang et al., 2017) [1]. Four kinds of copper responsive promoters were designed. Quantitative PCR (qPCR) was performed to determine relative mRNA levels of red fluorescent protein gene (rfp) extracted from cells grown under different concentrations of CuSO4. Three deletion vectors were constructed by using a copper-mediated self-excision cassette instead of a xylose-mediated self-excision cassette (Zhang et al., 2016) [2] to knock out xyn1, one of the two major specific endo-beta-1,4-xylanases (Rauscher et al., 2006) [3], xyr1, the key transcriptional activator of cellulolytic and xylanolytic genes (Lichius et al., 2015) [4], and ace3, a factor essential for cellulase production (Hakkinen et al., 2014) [5]. This data article reports the primers, vector construction, and qPCR assay. PMID- 29188231 TI - Forward and reverse mapping for milling process using artificial neural networks. AB - The data set presented is related to the milling process of AA6061-4.5%Cu-5%SiCp composite. The data primarily concentrates on predicting values of some machining responses, such as cutting force, surface finish and power utilization utilizing using forward back propagation neural network based approach, i.e. ANN based on three process parameters, such as spindle speed, feed rate and depth of cut.The comparing reverse model is likewise created to prescribe the ideal settings of processing parameters for accomplishing the desired responses as indicated by the necessities of the end clients. These modelling approaches are very proficient to foresee the benefits of machining responses and also process parameter settings in light of the experimental technique. PMID- 29188233 TI - The effects of scoliosis and subsequent surgery on the shape of the torso. AB - Background: Adolescent idiopathic scoliosis (AIS) causes asymmetry of the torso, and this is often the primary concern of patients. Surgery aims to minimise the visual asymmetry. It is not clear how scoliosis makes the torso asymmetric or how scoliosis surgery changes that asymmetry when compared to the distribution of asymmetries seen in a non-scoliotic group of normal controls. Methods: Surface topography images were captured for a group with AIS both pre-operatively and post-operatively. Identifiable points were compared between the images to identify the effects of AIS on the shape of the torso by looking at the relative heights and distances from the midline of the shoulders, axillae and waist in a two-dimensional coronal view. This was then compared to a previously reported group of normal non-scoliotic children to analyse whether surgery recreated normality. Results: There were 172 pairs of images with 164 females and 8 males, mean age at pre-operative scan of 13.7 years. The normal group was 642 images (237 females and 405 males) from 116 males and 79 females, mean age of 12.5 years.The curve patterns seen in the scoliotic group matched the patterns of a main thoracic curve (n = 146) and main thoracolumbar curve (n = 26). The asymmetries seen in both shoulders, axillae and waist were different between the two different types of curve. Across both groups, the shoulder asymmetry was less than that of the corresponding axillae.There was a statistically significant reduction in all asymmetries following surgery in the main thoracic group (p < 0.001). This was not seen in the main thoracolumbar group, thought to be due to the small sample size. In the main thoracic group, there were statistically significant differences in the asymmetries between the post-operative and normal groups in the shoulders and axillae (p < 0.001) but not the waist. Conclusions: This paper demonstrates quantitatively the range of asymmetries seen in the AIS torso and the degree to which surgery alters them. Surgery does not recreate normality but does cause a statistically significant change in torso shape towards that seen in a non-scoliotic group. PMID- 29188232 TI - Colorectal Cancer Cells Adhere to and Migrate Along the Neurons of the Enteric Nervous System. AB - Background & Aims: In several types of cancers, tumor cells invade adjacent tissues by migrating along the resident nerves of the tumor microenvironment. This process, called perineural invasion, typically occurs along extrinsic nerves, with Schwann cells providing physical guidance for the tumor cells. However, in the colorectal cancer microenvironment, the most abundant nervous structures belong to the nonmyelinated intrinsic enteric nervous system (ENS). In this study, we investigated whether colon cancer cells interact with the ENS. Methods: Tumor epithelial cells (TECs) from human primary colon adenocarcinomas and cell lines were cocultured with primary cultures of ENS and cultures of human ENS plexus explants. By combining confocal and atomic force microscopy, as well as video microscopy, we assessed tumor cell adhesion and migration on the ENS. We identified the adhesion proteins involved using a proteomics approach based on biotin/streptavidin interaction, and their implication was confirmed further using selective blocking antibodies. Results: TEC adhered preferentially and with stronger adhesion forces to enteric nervous structures than to mesenchymal cells. TEC adhesion to ENS involved direct interactions with enteric neurons. Enteric neuron removal from ENS cultures led to a significant decrease in tumor cell adhesion. TECs migrated significantly longer and further when adherent on ENS compared with on mesenchymal cells, and their trajectory faithfully followed ENS structures. Blocking N-cadherin and L1CAM decreased TEC migration along ENS structures. Conclusions: Our data show that the enteric neuronal network guides tumor cell migration, partly via L1CAM and N-cadherin. These results open a new avenue of research on the underlying mechanisms and consequences of perineural invasion in colorectal cancer.

AB - Radiolabeled cholesteryl ethers are widely used as non-metabolizable tracers for lipoproteins and lipid emulsions in a variety of in vitro and in vivo experiments. Since cholesteryl ethers do not leave cells after uptake and are not hydrolyzed by mammalian cellular enzymes, these compounds can act as markers for cumulative cell uptakes of labeled particles. We have employed [3H]cholesteryl oleoyl ether to study the uptake and distribution of triglyceride-rich emulsion particles on animal models. However, questionable unexpected results compelled us to analyze the stability of these ethers. We tested the stability of two commercially available radiolabeled cholesteryl ethers - [3H]cholesteryl oleoyl ether and [3H]cholesteryl hexadecyl ether from different suppliers, employing in vitro, in vivo and chemical model systems. Our results show that, among the two cholesteryl ethers tested, one ether was hydrolyzed to free cholesterol in vitro, in vivo and chemically under alkaline hydrolyzing agent. Free cholesterol, unlike cholesteryl ether, can then re-enter the circulation leading to confounding results. The other ether was not hydrolyzed to free cholesterol and remained as a stable ether. Hence, radiolabeled cholesteryl ethers should be analyzed for biological stability before utilizing them for in vitro or in vivo experiments.

AB - The late persistence in Southern Iberia of a Neandertal-associated Middle Paleolithic is supported by the archeological stratigraphy and the radiocarbon and luminescence dating of three newly excavated localities in the Mula basin of Murcia (Spain). At Cueva Anton, Mousterian layer I-k can be no more than 37,100 years-old. At La Boja, the basal Aurignacian can be no less than 36,500 years old. The regional Middle-to-Upper Paleolithic transition process is thereby bounded to the first half of the 37th millennium Before Present, in agreement with evidence from Andalusia, Gibraltar and Portugal. This chronology represents a lag of minimally 3000 years with the rest of Europe, where that transition and the associated process of Neandertal/modern human admixture took place between 40,000 and 42,000 years ago. The lag implies the presence of an effective barrier to migration and diffusion across the Ebro river depression, which, based on available paleoenvironmental indicators, would at that time have represented a major biogeographical divide. In addition, (a) the Phlegraean Fields caldera explosion, which occurred 39,850 years ago, would have stalled the Neandertal/modern human admixture front because of the population sink it generated in Central and Eastern Europe, and (b) the long period of ameliorated climate that came soon after (Greenland Interstadial 8, during which forests underwent a marked expansion in Iberian regions south of 40 degrees N) would have enhanced the "Ebro Frontier" effect. These findings have two broader paleoanthropological implications: firstly, that, below the Ebro, the archeological record made prior to 37,000 years ago must be attributed, in all its aspects and components, to the Neandertals (or their ancestors); secondly, that modern human emergence is best seen as an uneven, punctuated process during which long-lasting barriers to gene flow and cultural diffusion could have existed across rather short distances, with attendant consequences for ancient genetics and models of human population history. PMID- 29188236 TI - Novel Dominant-Negative GH Receptor Mutations Expands the Spectrum of GHI and IGF I Deficiency. AB - Context: Autosomal-recessive mutations in the growth hormone receptor (GHR) are the most common causes for primary growth hormone insensitivity (GHI) syndrome with classical GHI phenotypically characterized by severe short stature and marked insulin-like growth factor (IGF)-I deficiency. We report three families with dominant-negative heterozygous mutations in the intracellular domain of the GHR causing a nonclassical GHI phenotype. Objective: To determine if the identified GHR heterozygous variants exert potential dominant-negative effects and are the cause for the GHI phenotype in our patients. Results: All three mutations (c.964dupG, c.920_921insTCTCAAAGATTACA, and c.945+2T>C) are predicted to result in frameshift and early protein termination. In vitro functional analysis of variants c.964dupG and c.920_921insTCTCAAAGATTACA (c.920_921ins14) suggests that these variants are expressed as truncated proteins and, when coexpressed with wild-type GHR, mimicking the heterozygous state in our patients, exert dominant-negative effects. Additionally, we provide evidence that a combination therapy of recombinant human growth hormone (rhGH) and rhIGF-I improved linear growth to within normal range for one of our previously reported patients with a characterized, dominant-negative GHR (c.899dupC) mutation. Conclusion: Dominant-negative GHR mutations are causal of the mild GHI with substantial growth failure observed in our patients. Heterozygous defects in the intracellular domain of GHR should, therefore, be considered in cases of idiopathic short stature and IGF-I deficiency. Combination therapy of rhGH and rhIGF-I improved growth in one of our patients. PMID- 29188237 TI - Fewer Circulating Natural Killer Cells 28 Days After Double Cord Blood Transplantation Predicts Inferior Survival and IL-15 Response. AB - Natural Killer (NK) cell immune reconstitution after double umbilical cord blood transplantation (dUCBT) is rapid and thought to be involved in graft vs. leukemia (GvL) reactions. To investigate the role of NK cell recovery on clinical outcomes, the absolute number of NK cells at Day 28 after dUCBT was determined and patients with low numbers of NK cells had inferior two year disease-free survival (hazard ratio 1.96; p=0.04). A detailed developmental and functional analysis of the recovering NK cells was performed to link NK recovery and patient survival. The proportion of NK cells in each developmental stage was similar for patients with low, medium, and high Day 28 NK cell numbers. As compared to healthy controls, patients post-transplant showed reduced NK functional responses upon K562 challenge (CD107a, IFN-gamma, and TNFalpha); however, there were no differences based on Day 28 NK cell number. Patients with low NK numbers had 30% less STAT5 phosphorylation in response to exogenous IL-15 (p=0.04) and decreased Eomes expression (p=0.025) compared to patients with high NK numbers. Decreased STAT5 phosphorylation and Eomes expression may be indicative of reduced sensitivity to IL-15 in the low NK cell group. Incubation of patient samples with IL-15 superagonist (ALT803) increased cytotoxicity and cytokine production in all patient groups. Thus, clinical interventions, including administration of IL-15 early after transplantation may increase NK cell number and function and, in turn, improve transplantation outcomes. PMID- 29188238 TI - Depot medroxyprogesterone acetate administration alters immune markers for HIV preference and increases susceptibility of peripheral CD4+ T cells to HIV infection. AB - Depot medroxyprogesterone acetate (Depo-Provera) has been associated with an increased risk of HIV acquisition. In a longitudinal study, we investigated the impact of Depo-Provera use by healthy women on expression of immune markers for HIV preference and on HIV infection ex vivo at baseline (visit 1), one month (visit 2) and three months (visit 3) after Depo-Provera treatment. We found a significant increase in the frequency and expression of integrin alpha4beta7 on CD4+ T cells at visit 2. Interestingly, Hispanic but not black women exhibited a significant increase in integrin alpha4beta7 cell numbers and expression levels at visit 2, whereas, black but not Hispanic women exhibited a significant change in CCR5 and CD38 expression levels between visit 2 and visit 3. The frequency of terminal effector memory CD4+ T cells decreased significantly in black women from visit 1 to visit 3. Virus production following ex vivo HIV infection of PBMCs was increased at visit 3 compared to visit 1. In black women, the frequency of HIV p24+CD4+ T cells was higher at visit 3 than at visit 1. Expression of integrin alpha4beta7 on HIV p24+CD4+ T cells following ex vivo infection at visit 2 was significantly less than at visit 1. These results demonstrate that Depo-Provera alters the immune profile of peripheral CD4+ T cells and increases susceptibility to HIV infection ex vivo. The observation that these effects differed between women of different ethnicities has implications for developing effective and targeted strategies for HIV prevention. PMID- 29188239 TI - A graphene oxide nanosensor enables the co-delivery of aptamer and peptide probes for fluorescence imaging of a cascade reaction in apoptotic signaling. AB - Cytochrome c (Cyt c) and caspase-3 are the key mediators in apoptotic signaling. As is known to all, the release of Cyt c from mitochondria is a vital caspase activation pathway and defines the point of no-return in cell apoptosis. However, it has not been reported that any fluorescence imaging tools could allow simultaneous visualization of Cyt c translocation and caspase-3 activation in apoptotic cells. Here, we develop a sensitive nanosensor that holds the capability of imaging of the released Cyt c from the mitochondria and a caspase-3 activation cascade reaction in apoptotic signaling. The nanosensor is constructed by the assembly of a fluorophore (Cy5)-tagged DNA aptamer on graphene nanosheets that have been covalently immobilized with a FAM-labeled peptide. After a spatially selective delivery into the cytoplasm, the Cy5-tagged DNA aptamer assembled on the nanosensor can bind with Cyt c released from the mitochondria to the cytoplasm and dissociate from graphene, triggering a red fluorescence signal. In addition, the caspase-3 activated by the Cyt c released to the cytoplasm can cleave the FAM-labeled peptide and result in a green fluorescence output. The nanosensor exhibits rapid response, high sensitivity and selectivity for in vitro assays, and high contrast imaging of Cyt c and caspase-3 in living cells. It also provides the method for the study of the kinetic relationship between the Cyt c translocation and caspase-3 activation through simultaneous imaging of Cyt c and caspase-3. The developed nanosensor described here will be an efficient and potential platform for apoptosis research. PMID- 29188240 TI - SPIONs for cell labelling and tracking using MRI: magnetite or maghemite? AB - Although there is extensive literature covering the biomedical applications of superparamagnetic iron oxide nanoparticles (SPIONs), the phase of the iron oxide core used is not often taken into account when cell labelling and tracking studies for regenerative medicine are considered. Here, we use a co-precipitation reaction to synthesise particles of both magnetite- (Fe3O4) and maghemite- (gamma Fe2O3) based cores and consider whether the extra synthesis step to make maghemite based particles is advantageous for cell tracking. PMID- 29188241 TI - Microscopic understanding of the conformational features of a protein-DNA complex. AB - Protein-DNA interactions play crucial roles in different biological processes. Binding of a protein to its target DNA is the key step at different stages of genetic activities. In this article, we have carried out atomistic molecular dynamics simulations to understand the microscopic conformational and dynamical features of the N-terminal domain of the lambda-repressor protein and its operator DNA in their complexed state. The calculations revealed that the overall flexibility of the protein and the DNA components reduces due to complex formation. In particular, increased ordering of the DNA sugar rings bound to the protein is found to be associated with modified ring puckering. Attempts have been made to study the effect of complexation on the internal motions of the protein and the DNA components. It is demonstrated that the non-uniform ordering of the side chains of lysine residues in the consensus sequence leads to differential behavior of the two monomers of the homodimeric protein. PMID- 29188242 TI - Highly transparent and rollable PVA-co-PE nanofibers synergistically reinforced with epoxy film for flexible electronic devices. AB - The development of electronics towards a more functions-integrated, flexible and stretchable direction requires mechanically flexible substrates with high thermal and dimensional stability and optical transparency. Herein, rolls of an optically transparent PVA-co-PE nanofibrous membrane/epoxy composite with synergistically enhanced thermal stability, very low CTE, and outstanding mechanical properties are reported. The nanoscale size, the unique inter-stack structure, and the strong interfacial interactions between the PVA-co-PE nanofibers and the epoxy contribute to the synergistic effects. Because of the match between the refractive index (RI) of the PVA-co-PE nanofibers and the epoxy matrix, the visible light transmittance of nanocomposite film could be as high as 85% and the composite film was still optically transparent with a nanofiber loading content of up to 61.7 wt%. The break strength and compliance matrix of the composite film with a high fiber loading of 61.7 wt% increased by 2.3 times of that of the neat epoxy film and exceeded 3000 m2 N-1, respectively. PVA-co-PE nanofibers have a very low CTE value (3.634 * 10-6 K-1) and could be applicable as a reinforcement to reduce the thermal expansion of epoxy. Furthermore, we developed a flexible alternating current electroluminescent (ACEL) device based on the transparent composite film and the experimental results showed that the transparent composite film could serve as substrate for flexible electronic devices. In addition, their electrical and optical properties were evaluated. PMID- 29188243 TI - Cellular traction forces: a useful parameter in cancer research. AB - The search for new cancer biomarkers is essential for fundamental research, diagnostics, as well as for patient treatment and monitoring. Whereas most cancer biomarkers are biomolecules, an increasing number of studies show that mechanical cues are promising biomarker candidates. Although cell deformability has been shown to be a possible cancer biomarker, cellular forces as cancer biomarkers have been left largely unexplored. Here, we measure traction forces of cancer and normal-like cells at high spatial resolution using a robust method based on dense vertical arrays of nanowires. A force map is created using automated image analysis based on the localization of the fluorescent tips of the nanowires. We show that the force distribution and magnitude differ between MCF7 breast cancer cells and MCF10A normal-like breast epithelial cells, and that monitoring traction forces can be used to investigate the effects of anticancer drugs. PMID- 29188244 TI - Nitrilium ions - synthesis and applications. AB - Nitrilium ions have been well-established in organic chemistry for many decades, but recent developments show them to be far more versatile than hitherto recognized. They are known as stable salts, can be generated in situ, or are present as transient intermediates. We provide a succinct, but comprehensive review on the synthesis, stability, and reactivity of nitrilium ions as synthons for imines, their use in the synthesis of a large spectrum of heterocycles, and their reactions with transition metal complexes. By offering this overview, we aim for a renewed focus on readily accessible and simple to use nitrilium ions as valuable reagents for the synthesis of organic compounds. PMID- 29188245 TI - A microfluidic chip capable of generating and trapping emulsion droplets for digital loop-mediated isothermal amplification analysis. AB - Loop-mediated isothermal amplification (LAMP) is a nucleic acid amplification technique that rapidly amplifies specific DNA molecules at high yield. In this study, a microfluidic droplet array chip was designed to execute the digital LAMP process. The novel device was capable of 1) creating emulsion droplets, 2) sorting them into a 30 * 8 droplet array, and 3) executing LAMP across the 240 trapped and separated droplets (with a volume of 0.22 nL) after only 40 min of reaction at 56 degrees C. Nucleic acids were accurately quantified across a dynamic range of 50 to 2.5 * 103 DNA copies per MUL, and the limit of detection was a single DNA molecule. This is the first time that an arrayed emulsion droplet microfluidic device has been used for digital LAMP analysis. When compared to microwell digital nucleic acid amplification assays, this droplet array-based digital LAMP assay eliminates the constraint on the size of the digitized target, which was determined by the dimension of the microwells for its counterparts. Moreover, the capacity for hydrodynamic droplet trapping allows the chip to operate in a one-droplet-to-one-trap manner. This microfluidic chip may therefore become a promising device for digital LAMP-based diagnostics in the near future. PMID- 29188246 TI - Fast and scalable synthesis of uniform zirconium-, hafnium-based metal-organic framework nanocrystals. AB - Metal-organic frameworks based on zirconium or hafnium possess tantalizing commercial prospects due to their high stability but require a long reaction time to form crystals. The fast synthesis of uniform Zr-, Hf-MOF nanocrystals at scale is of key importance in the potential commercial application of MOFs. In this work, we have developed a versatile strategy through controlling the hydrolysis and nucleation of metal salts in the presence of acetic acid and water; up to 24 grams of UiO-66-NH2 nanocrystals with a uniform octahedron could be synthesized within 15 minutes using a one step method. The current synthetic strategy could be extended to other Zr-, Hf-MOF nanocrystals [UiO-66-Fast, UiO-66-(OH)2-Fast, UiO-66-2,6-NDC-Fast, UiO-67-Fast, BUT-12-Fast, PCN-222-Ni-Fast, PCN-222-Co-Fast, Hf-UiO-66-Fast, Hf-UiO-66-NH2-Fast, Hf-UiO-66-(OH)2-Fast, Hf-UiO-66-2,6-NDC-Fast and Hf-BUT-12-Fast]. Significantly, when noble metal nanoparticles (NPs) are introduced into MOF precursors, NPs encapsulated in MOFs with excellent dispersion have also been obtained and show outstanding performance in catalysis. This facile procedure is expected to pave the way to expand the commercial applications of MOFs. PMID- 29188247 TI - High quality and high performance adsorption of Congo red using as-grown MWCNTs synthesized over a Co-MOF as a catalyst precursor via the CVD method. AB - A Co(ii) metal-organic framework (MOF) based on the pyridyl-amide-carboxylate-3 (2-pyridinecarboxylic acid)amido pyridine (HPCAP) ligand, namely [Co(PCAP)2].2H2O (1), has been hydrothermally synthesized and structurally characterized, which was firstly used as a combined catalyst precursor to synthesize multi-walled carbon nanotubes (MWCNTs). The decomposition of ethylene in the presence of the Co-MOF by the chemical vapor deposition (CVD) method at 800 degrees C led to successful production of high quality as-grown MWCNT products. Interestingly, the as-grown MWCNTs exhibit high performance in the selective adsorption of Congo red (CR) with an adsorption capacity of 1639 mg g-1.

AB - Unsymmetrical one-pot sequential cross-coupling reactions of sterically hindered tetrabromothiophene with arylboronic acid and an alkyne/alkene to afford selective bi-, tri-, and tetrasubstituted aryl/alkynyl-thiophenes with the aid of a palladium catalyst were described. The reaction proceeds via a site-selective Suzuki/Sonogashira coupling, followed by selective Sonogashira, Suzuki and Heck coupling reactions. This methodology has demonstrated an important framework for the synthesis of organic scaffolds. PMID- 29188249 TI - Accessing multimetallic complexes with a phosphorus(i) zwitterion. AB - We present the synthesis of a zwitterionic triphosphenium molecule, tBu(C5H2)(PPh2)2PI (L), which can act as a single- or multidentate ligand with group 6, 7, 8 and 9 metal carbonyl complexes. Group 6, [M(CO)5L] complexes are formed under photolytic conditions, where the metal is bound at the P(i) center. In the case of Mo(CO)6, the bimetallic complex [M(CO)5LMo(CO)3] is generated, which features bonds to both the phosphorus(i) center and the cyclopentadienyl moiety of the molecule. Interestingly, group 7 and 9 metal carbonyl dimers generate bimetallic complexes in the form [M2(CO)nL], where both metal centers are bound at the phosphorus(i) center. A detailed analysis of these molecules is provided, including X-ray diffraction, multinuclear NMR, infrared spectroscopy and computational investigations. PMID- 29188250 TI - Honeycomb-patterned hybrid films of surfactant-encapsulated polyoxometalates by a breath figure method and its electrocatalysis for BrO3. AB - In this paper, a sandwich type of polyoxophosphotungstate K7Na3[Cu4(H2O)2(PW9O34)2].20H2O (abbr. Cu4(PW9)2) was selected as an active unit to construct inorganic/organic hybrid materials. The ordered honeycomb structure of the surfactant-encapsulated polyoxometalate (SEP) complex was successfully obtained by using a famous breath figure method. Cu4(PW9)2 maintains typical features as confirmed by IR spectra, magnetization hysteresis studies and UV-vis spectra. An investigation of the effects of the relative humidity on the morphology of the honeycomb structures demonstrated a wide generality and high reproducibility of the formation of self-organized honeycomb-patterned films. In the present experiment, this magnetically ordered honeycomb was successfully deposited on indium tin oxide (ITO) substrates by directly casting the SEP chloroform solution. The cyclic voltammetric responses showed the redox couples of Cu4(PW9)2. The electrochemical behavior of the electrode was studied. In addition, the modified electrode exhibited high electrocatalytic activity for the reduction of BrO3-, which offered a new POM-based film material for the electrochemical fields.

AB - The salt metathesis reaction of the sterically demanding bis(iminophosphoranyl)methanide alkali metal complexes LM (L- = HC(Ph2P[double bond, length as m-dash]NDip)2-, Dip = 2,6-iPr2C6H3; M = Li, Na, K) with "GaI", InBr or TlBr afforded the monomeric group 13 metal(i) complexes LE:, E = Ga (1), In (2) and Tl (3) in moderate yields, and small quantities of LGaI24 in the case of Ga, respectively. The molecular structures of LE: 1-3 from X-ray single crystal diffraction show them to contain puckered six-membered rings with N,N' chelating methanide ligands and two-coordinated metal(i) centres. Reduction reactions of LAlI25, prepared by iodination of LAlMe2, were not successful and no aluminium(i) congener could be prepared so far. DFT studies on LE:, E = Al-Tl, were carried out and support the formulation as an anionic, N,N'-chelating methanide ligand coordinating to group 13 metal(i) cations. The HOMOs of the molecules for E = Al-In show a dominant contribution from a metal-based lone pair that is high in s-character.

AB - A series of luminescent iridium(iii) complexes were designed and evaluated for their ability to detect oxalyl chloride ((COCl)2) at ambient temperature. In the presence of (COCl)2, a double amidation reaction takes place at the diamino functionality of complex 1, leading to the switching-on of a long-lived red luminescence with a 9-fold enhanced emission. Complex 1 exhibited high sensitivity and selectivity, with a detection limit for (COCl)2 at 32 nM. Additionally, complex 1 can be used to detect (COCl)2 using a simple smartphone, allowing for the portable and real-time monitoring of (COCl)2. PMID- 29188253 TI - Vibrational relaxation dynamics of beta-carotene and its derivatives with substituents on terminal rings in electronically excited states as studied by femtosecond time-resolved stimulated Raman spectroscopy in the near-IR region. AB - The electronic and vibrational relaxation of carotenoids is one of the key processes in the protection of living cells as well as in the functions of proteins involved in photosynthesis. In this study, the electronic and vibrational relaxation dynamics of beta-carotene and its derivatives with substituents on the terminal rings is investigated using femtosecond time resolved absorption and stimulated Raman spectroscopy in the near-IR region. The carbonyl substituent induces low-frequency shifts of the steady-state and transient absorption bands, decreases of the excited-state lifetimes and the acceleration of vibrational relaxation of the conjugated main chain, whereas the hydroxyl substituent only slightly affects them. The effects of the carbonyl group in the electronic relaxation dynamics are explained well by the lengthening of effective conjugation by the carbonyl group through a partial conjugation between the main chain and the terminal ring. Time-resolved near-IR stimulated Raman spectroscopy demonstrates the significance of the peripheral substitution with the carbonyl group for the vibrational energy relaxation of beta-carotene derivatives in the lowest excited singlet state. PMID- 29188254 TI - BODIPY dyes with thienyl- and dithienylthio-substituents - synthesis, redox and fluorescent properties. AB - 8-Phenyl- and 8-(4-nitrophenyl)-BODIPYs with thien-2-ylthio- and (2,2'-dithien-5 yl)-thio-substitution at the 3,5-positions were synthesized. 2-Thienylthio derivatives were obtained using two different sequences, i.e., via nucleophilic substitution in the corresponding 1,9-dichlorodipyrromethenes, followed by BODIPY formation and via the same reaction using 3,5-dichloro-BODIPY dyes. The "dipyrromethene route" was observed to result in better overall yields. All the dyes were characterized by UV-Vis and fluorescence spectroscopy as well as cyclic voltammetry (CVA) studies. The UV-Vis spectra exhibited slight dependence on the thiophene chain length. The thienylthio derivatives fluoresce with modest quantum yields; conversely, no fluorescence has been detected for their dithienylthio counterparts. 8-Phenyl-3,5-di(thien-2-ylthio)-BODIPY was characterized by X-ray crystallography, which showed the layered arrangement of the molecules. The thienyl fragments of different molecules in the same layer form pairs alike H aggregates, whereas the BODIPYs moieties in the different layers are arranged in a J-aggregate fashion. Solid fluorescence was observed for these crystals with a broad emission from 600 nm to longer than 850 nm. The CVA results correspond to those for known substituted BODIPYs except for the unusually high current observed for the oxidation process of the dithienyl derivatives with respect to the reduction process. This finding indicates oxidative film deposition. PMID- 29188255 TI - Electrogenerated chemiluminescence of Ru(bpy)32+ at a black phosphorus quantum dot modified electrode and its sensing application. AB - Black phosphorus quantum dots (BPQDs) with an average size of 8.2 nm were synthesized through a liquid exfoliation method. The surface morphology and the thickness of the BPQDs were identified by high-resolution transmission microscopy (HRTEM), atomic force microscopy (AFM), and Raman spectroscopy. The electrogenerated chemiluminescence (ECL) behavior of Ru(bpy)32+ was investigated at a BPQD modified glassy carbon electrode under neutral conditions. A strong anodic ECL signal was obtained at the modified electrode in the absence of a coreactant, which is nearly three orders of magnitude larger than that at the bare electrode. Electrochemical results revealed that the oxidation process of Ru(bpy)32+ can be significantly catalyzed by BPQDs, suggesting that BPQDs can act as the coreactant of Ru(bpy)32+ to generate strong light emission. Dopamine could react with the oxidation product of Ru(bpy)32+ and exhibited an apparent inhibiting effect on ECL emission. As a result, it can be sensitively detected in the range of 0.1 nM to 50 nM with a detection limit of 0.022 nM. The present work revealed that BPQDs are a potential ECL platform, and which are promising in the fabrication of a novel ECL biosensor. PMID- 29188256 TI - How the hydrogen sorption properties of palladium are modified through interaction with iridium. AB - Hydrogen sorption (adsorption/absorption) in metals, in the form of thin films or nanoparticles, is a key process in the fields of energy storage and heterogeneous catalysis. Atomic hydrogen dissolved in the subsurface of a metal affects its surface atomic and electronic structures, and thereby its surface reactivity and catalytic properties. In addition, alloy effects modify both catalytic and hydrogen sorption phenomena. In order to rationalize recent experimental results showing the negative impact of hydrogen absorption on catalysis, the present article proposes an insight into structure-reactivity relationships through computational simulations, using density functional theory, of hydrogen sorption in the near-surface region of palladium atomic layers interacting with an iridium substrate. A detailed analysis of the electronic structure using local projected densities of states (PDOS) and crystal orbital overlap population (COOP) curves was carried out. It is found that the Pd/Ir system, with respect to pure Pd surfaces, keeps acceptable adsorption properties for surface reactions while preventing hydrogen penetration. The results of electronic structure calculations show that the most important difference between Pd and Ir is related to the strong anti-bonding character of the 1s-H/5p-Ir interaction, leading to the non bonding character of the sp-Ir interaction with hydrogen. Thus, increasing the Ir concentration in a Pd-based system increases the anti-bonding contribution, which strongly weakens the overall metal-hydrogen interaction.

AB - Recent advances in exploiting microwave radiation in the topochemical modification of layered oxide perovskites are presented. Such methods work well for rapid bulk synthetic steps used in the production of novel inorganic-organic hybrids (protonation, grafting, intercalation, and in situ click reactions), exfoliation to produce dispersed nanosheets, and post-exfoliation processing to rapidly vary nanosheet surface groups. Compared to traditional methods that often take days, microwave methods can produce quality products in as little as 1-2 h. PMID- 29188258 TI - Filament dynamics in confined chemical gardens and in filiform corrosion. AB - Two reaction systems that are at first sight very different produce similar macroscopic filamentary product trails. The systems are chemical gardens confined to a Hele-Shaw cell and corroding metal plates that undergo filiform corrosion. We show that the two systems are in fact very much alike. Our experiments and analysis show that filament dynamics obey similar scaling laws in both instances: filament motion is nearly ballistic and fully self-avoiding, which creates self trapping events. PMID- 29188259 TI - High rate capability performance of ordered mesoporous TiNb6O17 microsphere anodes for lithium ion batteries. AB - We report the synthesis and application of ordered mesoporous TiNb6O17 microspheres (M-TNO) using a one-step solvothermal method for the first time in lithium-ion batteries. The diameters of TiNb6O17 microspheres are in the range from 2.2 to 2.4 MUm with a mesopore size of about 35 nm, which promotes the electron and ion migration in charge/discharge processes. M-TNO shows a high specific capacitance (307.2 mA h g-1) at a low current density of 0.2 C and a long-term cycle life over 500 cycles as an electrode. The retentive capacity of the batteries is 77% of the initial cycle after 500 cycles. It is worth noting that M-TNO exhibits excellent rate capacity, which decreases slowly from 265.7 to 172.4 mA h g-1 with the current density increasing from 1 C to 30 C. The retentive capacity at a current density of 30 C is 65% compared to that at 1 C. PMID- 29188260 TI - NO disproportionation by a {RhNO}9 pincer-type complex. AB - The reactivity of the {RhNO}9 complex [Rh(PCPtBu)(NO)] (1) with NO was studied. A disproportionation reaction takes place in which N2O is released quantitatively, while the complex Rh(PCPtBu)(NO)(NO2) (2), with coordinated nitrite, is formed. The new complex 2 was fully characterized by multinuclear NMR techniques, IR and X-ray diffraction. The X-ray structure reveals a square pyramidal geometry with an N-bound nitro ligand trans to the Cipso of the PCP ligand and a bent nitrosyl ligand in the apical position. IR measurement of released N2O confirms that one equivalent forms for each molecule of 1. Infrared spectroscopic experiments with 1-15NO and 14NO suggest that the reaction occurs through the intermediacy of a dinitrosyl complex. In addition, DFT calculations were performed to provide more evidence on the structure of the intermediates and to support the observed reactivity.

AB - Nano-sized SAPO-34 catalysts have been for the first time prepared using morpholine as the sole template by using a one-pot nanoseed-assisted method. The obtained nano-sized SAPO-34 catalysts exhibit about 4-fold prolonged lifetime and nearly 5% increased selectivity for ethylene and propylene compared to conventional micron-sized counterparts in methanol-to-olefin reactions.

AB - We have developed a trifunctional cleavable fluorescence turn-ON linker for chemoproteomic applications. This novel linker, which became highly fluorescent only upon cleavage of the azo bond, was successfully used for in situ proteome profiling/target identification and studies on newly synthesised proteomes. PMID- 29188263 TI - On the calculation of multiplet energies of three-open-shell 4f135fn6d1 electron configuration by LFDFT: modeling the optical spectra of 4f core-electron excitation in actinide compounds. AB - Methodological concepts are reported for the calculation, without empirical parameters, of multiplet energy levels and ligand-field effects associated with three-open-shell 4f135fn6d1 electron configurations, and for the modeling of X ray absorption spectra in relation to intra-atomic 5fn -> 4f135fn6d1 electron transitions. A density functional theory (DFT) method is used for the determination of the electronic structure. An effective ligand-field Hamiltonian is also used to incorporate many body effects and corrections via the configuration interaction algorithm within the active space of Kohn-Sham orbitals with dominant actinide 4f, 5f and 6d characters. The theoretical method ensures a parameter-free ligand-field model, which will be implemented in the Amsterdam density functional (ADF) program package as part of the available and automated ligand-field density functional theory (LFDFT) routine. The theoretical method is illustrated with examples for applications: U4+ in the free ion and U4+ in bulk UO2 by means of the molecular (UO8)12- cluster. The DFT calculations are performed at different levels of the DFT functional, from which the LFDFT parameters such as Slater-Condon integrals, spin-orbit coupling constants and ligand-field potential (represented within the Wybourne formalism) are emulated. The comparison with available experimental data is good. Therefore, a non empirical ligand-field treatment of the 4f135fn6d1 configuration is established illustrating the spectroscopic details of the 4f core-electron excitation, which can be valuable for further understanding and prediction of the spectral profiles of actinide N6,7-edge X-ray absorption spectroscopy.

AB - We report the long-term stability of water-sensitive hybrid perovskites CH3NH3PbI3 that were protected with monolayer graphene. This successful passivation was enabled by our development of a new water-free and polymer-free graphene transfer method. Monolayer graphene samples grown by plasma-enhanced chemical vapor deposition and transferred onto different substrates with the water/polymer-free method were found to preserve their high-quality characteristics after the transfer, as manifested by the studies of Raman, X-ray and ultraviolet photoemission spectroscopy (XPS and UPS), optical absorption, and sheet resistance. Additionally, XPS, UPS and optical absorption studies of fully graphene-covered CH3NH3PbI3 thin films showed spectral invariance even after 3 months, which was in sharp contrast to the drastic spectral changes after merely one week in control CH3NH3PbI3 samples without graphene protection. This successful demonstration of the graphene-enabled passivation and long-term stability of CH3NH3PbI3 thin films therefore opens up a new pathway towards realistic photovoltaic applications of hybrid perovskites.

AB - In this article, the synthesis and applications of selected ammonium tagged Ru alkylidene metathesis catalysts were described. Because of the straightforward synthesis, the first generation of onium-tagged catalysts have the ammonium group installed in the benzylidene ligand. Such catalysts usually give relatively pure metathesis products, and are used in polar solvents and water, or immobilised on various supports. Later, catalysts tagged in the N-heterocyclic carbene ligand (NHC) were developed to offer higher stability and even lower metal contamination levels. Due to minimal leaching, the non-dissociating ligand tagged systems were successfully immobilised on various supports, including zeolites and Metal Organic Frameworks (MOFs) and used in batch and in continuous flow conditions. PMID- 29188266 TI - Termination of Ge surfaces with ultrathin GeS and GeS2 layers via solid-state sulfurization. AB - Reactions of Ge with S vapor, of interest as a potential approach for forming thin passivation layers on Ge surfaces, have been studied by photoelectron spectroscopy and Raman spectroscopy. Exposure of Ge(100) and Ge(111) to S drives the formation of Ge sulfide near-surface layers. At low temperatures, the reaction products comprise a thin GeS interlayer terminated by near-surface GeS2. Above 400 degrees C, exposure to sulfur gives rise to single-phase GeS2 layers whose thickness increases with temperature. Arrhenius analysis of the GeS2 thickness yields an activation energy (0.63 +/- 0.08) eV, close to the barrier that controls Ge oxidation by O radicals. XPS measurements after extended ambient exposure show a stable, ultrathin near-surface GeS2 without significant oxidation, indicating that Ge-sulfides may provide an effective surface passivation for Ge surfaces.

AB - In this paper we show that the active interplay of nonlinear kinetics and transport phenomena in a chemical oscillator can be exploited to induce and control chaos. To this aim we use as a model system the ferroin-catalysed Belousov-Zhabotinsky (BZ) oscillating reaction, which is known to evolve to characteristic chaotic transient dynamics when carried out under batch and unstirred conditions. In particular, chemical chaos was found to appear and disappear by following a Ruelle-Takens-Newhouse (RTN) scenario. Here we use medium viscosity as a bifurcation parameter to tune the reaction-diffusion convection (RDC) interplay and force the reaction in a specific sequence of dynamical regimes: either (i) periodic -> quasi-periodic -> chaotic or (ii) periodic -> quasi-periodic or (iii) only periodic. The medium viscosity can be set by adding different amounts of surfactant (sodium dodecyl sulphate), known to have a little impact on the reaction mechanism, above its critical micelle concentration. Experimental results are supported by means of numerical simulations of a RDC model, which combines self-sustained oscillations to the related chemically-induced buoyancy convection.

PMID- 29188268 TI - Sensitivity of Preference-Based Quality-of-Life Measures for Economic Evaluations in Early-Stage Melanoma. AB - Importance: The diagnosis of a life-threatening disease like melanoma can affect all aspects of a person's life, including health-related quality of life (HRQOL) and psychological aspects of melanoma such as fear of cancer recurrence (FCR). Economic evaluations of psychological interventions require preference-based (utility) instruments that are sensitive to changes in well-being and HRQOL; however, very few studies have evaluated the sensitivity of these instruments when used for people with melanoma. Objective: To compare utility scores from the multiple-attribute instrument Assessment of Quality of Life-8-Dimension Scale (AQoL-8D) with the mapped utility scores of the Functional Assessment of Cancer Therapy-Melanoma (FACT-M) and to investigate the sensitivity of both instruments in identifying the influence of FCR on HRQOL. Design, Setting, and Participants: This assessment of data from a randomized clinical trial of a psychoeducational intervention to reduce FCR, conducted at 3 high-risk melanoma clinics in Australia, evaluated 164 patients with early-stage melanoma and a high risk of developing a second primary melanoma. Main Outcomes and Measures: The FACT-M and AQoL-8D were used to assess HRQOL and FCR among the study participants. Concurrent validity was assessed by comparing the total and subdomain scores of the 2 instruments, and the strength of associations was assessed using Pearson correlation coefficient. Convergent validity was assessed by comparing participants' HRQOL, demographic, and clinical characteristics using the chi2 test and F statistic. Both the FACT-M and AQoL-8D utilities were regressed on FCR Inventory (FCRI) severity scores to estimate the effect of elevated FCR on HRQOL. Results: A total of 164 participants completed the baseline questionnaires, but only 163 met all inclusion criteria and underwent the full analysis: 72 were women; 91 were men; and mean (SD) age was 58.2 (12.1) years. Both the AQoL-8D and FACT-M instruments showed good concurrent validity and could differentiate between relevant subgroups including level of FCRI severity. The AQoL-8D and FACT M utilities were strongly correlated (r2 = 0.57). Respondents had a mean (SD) AQoL-8D utility of 0.77 (0.2), and a mean (SD) FACT-M utility score of 0.76 (0.07). High levels of FCRI severity were associated with a decrease in utility of 0.12 (95% CI, -0.19 to -0.05) as measured by AQoL-8D, and a decrease of 0.03 (95% CI, -0.05 to -0.01) as measured by the FACT-M. Conclusions and Relevance: For economic evaluations of psychological interventions in melanoma, the AQoL-8D and FACT-M are valid measures of utility; however, the AQoL-8D demonstrates greater sensitivity to FCRI severity. Our results suggest a significant association between FCR and HRQOL. PMID- 29188271 TI - A Rare Cause of Small-Bowel Ischemia.

PMID- 29188270 TI - Tracking the Growth of Tense and Agreement in Children With Specific Language Impairment: Differences Between Measures of Accuracy, Diversity, and Productivity. AB - Purpose: Composite measures of children's use of tense and agreement morphology differ in their emphasis on accuracy, diversity, or productivity, yet little is known about how these different measures change over time. An understanding of these differences is especially important for the study of children with specific language impairment, given these children's extraordinary difficulty with this aspect of grammar. Method: We computed 3 types of composite scores from spontaneous speech samples obtained from 17 preschoolers with specific language impairment before, during, and after their participation in a language intervention study. These measures were the Finite Verb Morphology Composite (a measure of accuracy), the Tense Marker Total (a measure of diversity), and the Productivity Score (a measure of productivity). Results: The 3 measures differed in their growth trajectories. Sample size did not alter the linear or quadratic nature of growth of any composite, although it did affect the absolute values found for the Tense Marker Total and Productivity Score. Conclusion: Even when sample size is controlled, early growth can be seen in tense and agreement accuracy with relatively limited diversity and productivity, whereas later growth in diversity and productivity can occur with very little change in accuracy.

AB - Purpose: Potential biases in service provision for preschool children with specific language impairment (SLI) were explored. Method: In Study 1, children with SLI receiving treatment (SLI-T) and those with SLI not receiving treatment (SLI-NT) were compared on demographic characteristics and developmental abilities. Study 2 recruited children with articulation disorders receiving treatment (ARTIC-T) to determine if knowing service provision status influenced the results of Study 1. Results: In Study 1, the SLI-T group was rated by teachers as having poorer executive functioning than children in the SLIT-NT group, and the SLI-T group also came from families whose mothers had more education. These 2 variables alone predicted SLI-T and SLI-NT group membership with 84% accuracy. In Study 2, the ARTIC-T group were perceived as having comparable executive functioning to the SLI-NT group and better than the SLI-T group, indicating that teachers' knowledge of service provision did not influence their ratings of children's executive functioning. Discussion: Preschool children with SLI, whose mothers have higher education levels and whose teachers perceive them as having poorer executive functioning, are more likely to receive intervention. Recognizing service delivery biases is critical for improving early provision of intervention for this population.

AB - Purpose: Using American Speech-Language-Hearing Association's (ASHA's) National Outcomes Measurement System (NOMS) Functional Communication Measure (FCM) as a common metric, this investigation compared traditional service delivery and telepractice service delivery for children receiving therapy for the NOMS diagnostic category of "speech sound production." Method: De-identified cases were secured from ASHA's NOMS database and a proprietary database from a private e-learning provider. Cases were included if they met 3 criteria: (a) children received treatment exclusively for speech sound production, (b) they were between 6.0 and 9.5 years old, and (c) they received therapy lasting between 4 and 9 months. A total of 1,331 ASHA NOMS cases and 428 telepractice cases were included. The 2 groups were matched by initial FCM scores. Mann-Whitney U tests were completed to compare differences in the median change scores (the difference between the initial and final FCM scores) between the 2 groups. Results: There were no significant differences in the median change scores between the traditional group and the telepractice group. Conclusions: These results suggest comparable treatment outcomes between traditional service delivery and telepractice for treatment of children exhibiting speech sound disorders. The findings provide support for the use of telepractice for school-age children. PMID- 29188279 TI - Simulation Models of Therapy Intensification in Lipid-Lowering Medicine-Reply.

AB - Importance: The histiocytic neoplasms Erdheim-Chester disease (ECD) and Langerhans cell histiocytosis (LCH) are highly enriched for BRAF V600 mutations and have been previously shown to be responsive to treatment with vemurafenib, an inhibitor of the BRAF V600 kinase. However, the long-term efficacy and safety of prolonged vemurafenib use in these patients are not defined. Here we analyze the final efficacy and safety data for vemurafenib in patients with ECD and LCH enrolled in the VE-BASKET study. Objective: To determine the efficacy and safety of vemurafenib in adults with ECD or LCH enrolled in the VE-BASKET study. Design, Setting, and Participants: The VE-BASKET study was an open-label, nonrandomized, multicohort study for patients with nonmelanoma cancers harboring the BRAF V600 mutation. Patients with BRAF V600-mutant ECD or LCH were enrolled in an "other solid tumor" cohort of the VE-BASKET study, and they were enrolled in the present study. Interventions: Patients received vemurafenib, 960 mg, twice daily continuously until disease progression, study withdrawal, or occurrence of intolerable adverse effects. Main Outcomes and Measures: The primary end point was confirmed objective response rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1). Secondary end points included progression free survival (PFS), overall survival (OS), metabolic response by modified positron-emission tomography (PET) Response Criteria in Solid Tumors (PERCIST) using 18F-fluorodeoxyglucose (FDG)-PET/computed tomography (CT), and safety. Results: A total of 26 patients from the VE-BASKET trial (22 with ECD, 4 with LCH) were included in the present study (14 women and 12 men; median age, 61 years; age range, 51-74 years). The confirmed ORR was 61.5% (95% CI, 40.6%-79.8%) in the overall cohort and 54.5% (95% CI, 32.2%-75.6%) in patients with ECD. All evaluable patients achieved stable disease or better. The median PFS and OS had not been reached in the overall cohort at study closure despite a median follow up of 28.8 months; 2-year PFS was 86% (95% CI, 72%-100%), and 2-year OS was 96% (95% CI, 87%-100%). All 15 patients evaluated by FDG-PET/CT achieved a metabolic response, including 12 patients (80%) with a complete metabolic response. The most common adverse events (AEs) in the overall cohort included arthralgia, maculopapular rash, fatigue, alopecia, prolonged QT interval, skin papilloma, and hyperkeratosis. Hypertension and dermatologic AEs occurred at higher rates than those reported in metastatic melanoma. Conclusions and Relevance: In this study, vemurafenib had prolonged efficacy in patients with BRAF V600-mutant ECD and LCH and warrants consideration as a new standard of care for these patients. PMID- 29188285 TI - Association of Exercise Preconditioning With Immediate Cardioprotection: A Review. AB - Importance: Exercise reduces the risk of cardiovascular events, including through an underrecognized, clinically useful form of acute cardioprotection accessible after a single episode of exercise, which is called cardiovascular preconditioning. Observations: Preclinical evidence shows that 1 to 3 episodes of exercise per week will provide strong cardioprotection; gradual, modest cardiovascular risk factor modification or physiological artery remodeling cannot fully explain these benefits. This review highlights preclinical evidence that acute exercise-induced cardiac preconditioning has the ability to activate multiple pathways to confer immediate protection against ischemic events, reduce the severity of potentially lethal ischemic myocardiac injury, and act as a physiological first line of defense. Conclusions and Relevance: Independent of the protective benefits of long-term exercise training on risk factors and adaptation of the cardiovascular system, cardiovascular preconditioning may contribute to the immediate cardioprotection of exercise. In practical terms, this means that 1 episode of exercise can create clinically relevant cardioprotection. PMID- 29188286 TI - Association of Dermatologist Density With the Volume and Costs of Dermatology Procedures Among Medicare Beneficiaries. AB - Importance: The persistent shortage of dermatologists in the United States affects access to care and patient outcomes. Objective: To characterize the effect of geographic variations in dermatologist density on the provision of dermatology procedures within Medicare. Design, Setting, and Participants: This was a cross-sectional study using the 2013 Medicare Provider Utilization and Payment Database. Dermatology-related procedures were defined by the top 50 billing codes accounting for more than 95% of procedures billed by dermatologists. Billing codes corresponding to evaluation and monitoring visits and dermatopathology were excluded. Total costs were estimated from the Centers for Medicare & Medicaid Services physician fee schedule, based on the nonfacility national payment amount with no modifiers. Nationally representative administrative database that includes 100% of charges billed by noninstitutional clinicians covered under Medicare Part B. A total of 10 391 dermatologists practicing within the 50 states and Washington, DC, were included. The Medicare eligible population was defined as all persons 65 years or older. Exposures: Density of dermatologists, categorized into first (5.3 per 100 000 persons >=65 years) through fifth (54.8 per 100 000 persons >=65 years) quintiles. Main Outcomes and Measures: Utilization of dermatology procedures (mean volume per 100 000 persons >=65 years) and total cost (mean amount billed per person >=65 years) by clinician type across quintiles of dermatologist density. Results: In 2013, dermatologists billed Medicare for 28 million procedures costing $2.21 billion. Mean billed amount by dermatologists per person 65 years or older was $15.87 in the lowest-density quintile vs $92.02 in the highest-density quintile. This trend suggests that each interval increase of 10 dermatologists per 100 000 persons 65 years or older is correlated with a $14.81 increase in Medicare spending on dermatology procedures (95% CI, 8.28-21.34; P = .005). Utilization of these procedures differed among clinician types, with dermatologists largely performing destruction of premalignant lesions and PCPs primarily doing injections. Conclusions and Relevance: There is evidence of supply-sensitive variation in the provision of dermatology procedures for the Medicare-eligible population; higher dermatologist density is correlated with increased utilization of dermatology procedures and subsequent billed charges to Medicare. Further research is needed to determine the effect of such variations on outcomes and whether incentives can better align dermatologists with areas of clinical need.

PMID- 29188292 TI - Association of the World War II Finnish Evacuation of Children With Psychiatric Hospitalization in the Next Generation. AB - Importance: Although there is evidence that adverse childhood experiences are associated with worse mental health in adulthood, scarce evidence is available regarding an emerging concern that the next generation might also be affected. Objective: To compare the risk of psychiatric hospitalization in cousins whose parents were vs were not exposed to the Finnish evacuation policy that involved a mean 2-year stay with a Swedish foster family. Design, Setting, and Participants: This multigenerational, population-based cohort study of Finnish individuals and their siblings born between January 1, 1933, and December 31, 1944, analyzed the association of evacuee status as a child during World War II in the first generation with the risk of psychiatric hospitalization among offspring in the second generation. Evacuee status during World War II was determined using the Finnish National Archive's registry of participants in the Finnish evacuation. Data on evacuee status were linked to the psychiatric diagnoses in the Finnish Hospital Discharge Register from January 1, 1971, through December 31, 2012, for offspring (n = 93 391) born between January 1, 1950, and December 31, 2010. Sex specific Cox proportional hazards regression models were used to estimate hazard ratios for risk of psychiatric hospitalization during the follow-up period. Because offspring of evacuees and their nonevacuated siblings are cousins, the Cox proportional hazards regression models included fixed effects to adjust for confounding factors in families. Data analysis was performed from June 15, 2016, to August 26, 2017. Exposures: Parental participation in the evacuation during World War II (coded 1 for parents who were evacuated and placed in foster care and 0 for those not evacuated). Main Outcomes and Measures: Offspring's initial admission to the hospital for a psychiatric disorder, obtained from the Finnish Hospital Discharge Register from January 1, 1971, through December 31, 2012. Results: Of the 93 391 study persons, 45 955 (49.2%) were women and 47 436 (50.8) were men; mean (SD) age in 2012 among survivors was 45.4 (6.58) years. Female offspring of mothers evacuated to Sweden during childhood had an elevated risk of psychiatric hospitalization (hazard ratio for any type of psychiatric disorder: 2.04 [95% CI, 1.04-4.01]; hazard ratio for mood disorder: 4.68 [95% CI, 1.92 11.42]). There was no excess risk of being hospitalized for a psychiatric disorder among women whose fathers were exposed to the Finnish evacuation policy during World War II or among men whose mothers or fathers were exposed. Conclusions and Relevance: In a prior follow-up study of the Finnish evacuees, girls evacuated to Swedish foster families during World War II were more likely to be hospitalized for a psychiatric disorder-in particular, a mood disorder-in adulthood than their nonevacuated sisters. The present study found that the offspring of these individuals were also at risk for mental health problems that required hospitalization and suggests that early-life adversities, including war related exposures, may be associated with mental health disorders that persist across generations. PMID- 29188293 TI - Variation of Thyroidectomy-Specific Outcomes Among Hospitals and Their Association With Risk Adjustment and Hospital Performance. AB - Importance: Current surgical quality metrics might be insufficient to fully judge the quality of certain operations because they are not procedure specific. Hypocalcemia, recurrent laryngeal nerve (RLN) injury, and hematoma are considered to be the most relevant outcomes to measure after thyroidectomy. Whether these outcomes can be used as hospital quality metrics is unknown. Objectives: To evaluate whether thyroidectomy-specific outcomes vary among hospitals, whether the addition of thyroidectomy-specific variables affects risk adjustment, and whether differences in hospital performance are associated with thyroidectomy specific care processes. Design, Setting, and Participants: In this retrospective cohort study, patients undergoing thyroidectomies from January 1, 2013, through December 31, 2015, at hospitals participating in the American College of Surgeons' National Surgical Quality Improvement Program were studied. Exposure: Thyroidectomy-related care. Main Outcomes and Measures: Clinically severe hypocalcemia, RLN injury, and clinically significant hematoma within 30 days of thyroid surgery and hospital-level performance variation, change in risk adjustment, and association with processes. Results: Overall, 14 540 patients (mean [SD] age, 52.1 [15.0] years; 11 499 [79.1%] female) underwent operations at 98 hospitals. Because operations missing thyroidectomy-specific outcomes were excluded, the numbers of operations and hospitals analyzed differed by outcome. Of 14 540 operations included, clinically severe hypocalcemia occurred in 450 patients (3.3% overall, 0.6% after partial, and 4.7% after subtotal or total thyroidectomy), RLN injury in 755 patients (5.7% overall, 4.2% after partial, and 6.6% after subtotal or total thyroidectomy), and hematoma in 175 patients (1.3%). Hospital performance varied for hypocalcemia and RLN injury but not for hematoma. Hospital performance rankings were largely unaffected by the inclusion of thyroidectomy-specific data in risk adjustment. With regard to processes, patients undergoing thyroidectomies at the best-performing vs worst-performing hospitals less frequently had their postoperative parathyroid hormone level measured (593 [19.9%] vs 457 [31.7%], P < .001) and more often were prescribed oral calcium, vitamin D, or both (2281 [76.6%] vs 962 [66.8%], P < .001). When profiled by RLN injury, use of energy devices (1517 [69.1%] vs 507 [55.2%], P < .001) and intraoperative nerve monitoring (1223 [55.7%] vs 346 [37.7%], P < .001) were more prevalent at the best- compared with the worst-performing hospitals. Conclusions and Relevance: Postoperative hypocalcemia and RLN injury, but not hematoma, potentially could be used as thyroidectomy-specific national hospital quality improvement metrics. Strategies aimed at reducing these complications after thyroidectomy may improve the care of these patients. PMID- 29188294 TI - Genetic Association of Lipids and Lipid Drug Targets With Abdominal Aortic Aneurysm: A Meta-analysis. AB - Importance: Risk factors for abdominal aortic aneurysm (AAA) are largely unknown, which has hampered the development of nonsurgical treatments to alter the natural history of disease. Objective: To investigate the association between lipid associated single-nucleotide polymorphisms (SNPs) and AAA risk. Design, Setting, and Participants: Genetic risk scores, composed of lipid trait-associated SNPs, were constructed and tested for their association with AAA using conventional (inverse-variance weighted) mendelian randomization (MR) and data from international AAA genome-wide association studies. Sensitivity analyses to account for potential genetic pleiotropy included MR-Egger and weighted median MR, and multivariable MR method was used to test the independent association of lipids with AAA risk. The association between AAA and SNPs in loci that can act as proxies for drug targets was also assessed. Data collection took place between January 9, 2015, and January 4, 2016. Data analysis was conducted between January 4, 2015, and December 31, 2016. Exposures: Genetic elevation of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG). Main Outcomes and Measures: The association between genetic risk scores of lipid-associated SNPs and AAA risk, as well as the association between SNPs in lipid drug targets (HMGCR, CETP, and PCSK9) and AAA risk. Results: Up to 4914 cases and 48 002 controls were included in our analysis. A 1-SD genetic elevation of LDL-C was associated with increased AAA risk (odds ratio [OR], 1.66; 95% CI, 1.41-1.96; P = 1.1 * 10-9). For HDL-C, a 1 SD increase was associated with reduced AAA risk (OR, 0.67; 95% CI, 0.55-0.82; P = 8.3 * 10-5), whereas a 1-SD increase in triglycerides was associated with increased AAA risk (OR, 1.69; 95% CI, 1.38-2.07; P = 5.2 * 10-7). In multivariable MR analysis and both MR-Egger and weighted median MR methods, the association of each lipid fraction with AAA risk remained largely unchanged. The LDL-C-reducing allele of rs12916 in HMGCR was associated with AAA risk (OR, 0.93; 95% CI, 0.89-0.98; P = .009). The HDL-C-raising allele of rs3764261 in CETP was associated with lower AAA risk (OR, 0.89; 95% CI, 0.85-0.94; P = 3.7 * 10-7). Finally, the LDL-C-lowering allele of rs11206510 in PCSK9 was weakly associated with a lower AAA risk (OR, 0.94; 95% CI, 0.88-1.00; P = .04), but a second independent LDL-C-lowering variant in PCSK9 (rs2479409) was not associated with AAA risk (OR, 0.97; 95% CI, 0.92-1.02; P = .28). Conclusions and Relevance: The MR analyses in this study lend support to the hypothesis that lipids play an important role in the etiology of AAA. Analyses of individual genetic variants used as proxies for drug targets support LDL-C lowering as a potential effective treatment strategy for preventing and managing AAA. PMID- 29188295 TI - Association of Environment With the Risk of Developing Psychotic Disorders in Rural Populations: Findings from the Social Epidemiology of Psychoses in East Anglia Study. AB - Importance: Social determinants are important risk factors for the development of first-episode psychosis (FEP); their effects in rural areas are largely unknown. Objective: To investigate neighborhood-level factors associated with FEP in a large, predominantly rural population-based cohort. Design, Setting, and Participants: This study extracted data on referrals for treatment of potential FEP at 6 Early-Intervention Psychosis services from the Social Epidemiology of Psychoses in East Anglia naturalistic cohort study data set, which covered a population of more than 2 million people in a rural area in the East of England for a period of 3.5 years. All individuals aged 16 to 35 years who presented to Early-Intervention Psychosis services and met diagnostic criteria for first episodes of nonaffective psychoses and affective psychoses (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnostic codes F20-33) were included (n = 631). Persons whose disorders had an organic basis (diagnostic codes F06.X) and those meeting the criteria for substance-induced psychosis (diagnostic codes F1X.5) were excluded. We derived 4 neighborhood-level exposures from a routine population data set using exploratory factor analysis (racial/ethnic diversity, deprivation, urbanicity, and social isolation) and investigated intragroup racial/ethnic density and fragmentation. Main Outcomes and Measures: Multilevel Poisson regression was performed to determine associations between incidence rates and neighborhood-level factors, after adjustment for individual factors. Results were reported as incidence rate ratios (IRRs). Results: The study included 631 participants who met criteria for FEP and whose median age at first contact was 23.8 years (interquartile range, 19.6-27.6 years); 416 of 631 (65.9%) were male. Crude incidence of FEP was calculated as 31.2 per 100 000 person-years (95% CI, 28.9-33.7). Incidence varied significantly between neighborhoods after adjustment for age, sex, race/ethnicity, and socioeconomic status. For nonaffective psychoses, incidence was higher in neighborhoods that were more economically deprived (IRR, 1.13; 95% CI, 1.06-1.20) and socially isolated (IRR, 1.11; 95% CI, 1.04-1.19). It was lower in more racially/ethnically diverse neighborhoods (IRR, 0.94; 95% CI, 0.87-1.00). Higher intragroup racial/ethnic density (IRR, 0.97; 95% CI, 0.94-1.00) and lower intragroup racial/ethnic fragmentation (IRR, 0.98; 95% CI, 0.96-1.00) were associated with a reduced risk of affective psychosis. Conclusions and Relevance: Spatial variation in the incidence of nonaffective and affective psychotic disorders exists in rural areas. This suggests that the social environment contributes to psychosis risk across the rural-urban gradient.

PMID- 29188299 TI - Are work organization interventions effective in preventing or reducing work related musculoskeletal disorders? A systematic review of the literature. AB - Objectives We sought to determine whether interventions that target work organization or the psychosocial work environment are effective in preventing or reducing work-related musculoskeletal disorders (WMSD) compared to usual work. Methods We systematically reviewed the 2000-2015 English- and French-language scientific literature, including studies evaluating the effectiveness of an organizational or psychosocial work intervention on incidence, prevalence or intensity of work-related musculoskeletal pain or disorders in the neck, shoulders, upper limbs and/or back or of work absence due to such problems, among non-sick-listed workers. We excluded rehabilitation and individual-level behavioral interventions and studies with >50% attrition. We analyzed medium- and high-quality studies and synthesized the evidence using the Grading of Recommendations Assessment, Development & Evaluation (GRADE) approach. An analysis of key workplace intervention elements supplemented the interpretation of results. Results We identified 884 articles; 28 met selection criteria, yielding 2 high-quality, 10 medium-quality and 16 low-quality studies. There was moderate evidence that supplementary breaks, compared to conventional break schedules, are effective in reducing symptom intensity in various body regions. Evidence was low-to-very-low quality for other interventions, primarily due to risk of bias related to study design, high attrition rates, co-interventions, and insensitive indicators. Most interventions lacked key intervention elements, such as work activity analysis and ergonomist guidance during implementation, but the relation of these elements to intervention effectiveness or ineffectiveness remains to be demonstrated. Conclusions Targeting work-rest cycles may reduce WMSD. Better quality studies are needed to allow definitive conclusions to be drawn on the effectiveness of other work organizational or psychosocial interventions to prevent or reduce WMSD. PMID- 29188298 TI - Adjuvant Sandwich Chemotherapy Plus Radiotherapy vs Adjuvant Chemotherapy Alone for Locally Advanced Bladder Cancer After Radical Cystectomy: A Randomized Phase 2 Trial. AB - Importance: Locoregional failure for patients with locally advanced bladder cancer (LABC) after radical cystectomy (RC) is common even with chemotherapy and is associated with high morbidity and mortality. Adjuvant radiotherapy (RT) can decrease locoregional failure but has not been studied in the chemotherapy era. Objective: To investigate if adjuvant sequential RT plus chemotherapy can improve locoregional recurrence-free survival (LRFS) compared with adjuvant chemotherapy alone. Design, Setting, and Participants: A randomized phase 3 trial was opened to compare adjuvant RT vs sequential chemotherapy plus RT after RC for LABC, but a third arm was added later as a randomized phase 2 trial to compare chemotherapy plus RT vs adjuvant chemotherapy alone, an emerging standard. The intent-to-treat phase 2 trial reported herein enrolled patients from December 2002 to July 2008. Data were analyzed from August 3, 2015, to January 6, 2016. Routine follow-up and surveillance pelvic computed tomographic (CT) scans every 6 months during the first 2 years were performed. The setting was an academic center. Patients with bladder cancer 70 years or younger having 1 or more risk factors (>=pT3b, grade 3, or positive nodes) with negative margins after radical cystectomy plus pelvic lymph node dissection were eligible. Patients had Eastern Cooperative Oncology Group performance status of 0 to 2, no evidence of distant metastases on CT scan of the abdomen and pelvis or on chest imaging, and adequate renal, hepatic, and hematologic function. Ninety-one percent (109 of 120) had >= pT3 disease. Interventions: Chemotherapy plus RT included 2 cycles of gemcitabine (1000 mg/m2 intravenously on days 1, 8, and 15) and cisplatin (70 mg/m2 intravenously on day 2) before and after RT to 4500 cGy in 150 cGy twice-daily fractions over 3 weeks using 3-dimensional conformal techniques. Chemotherapy alone included 4 cycles of gemcitabine and cisplatin. Main Outcome and Measure: Locoregional recurrence-free survival. Results: The chemotherapy plus RT arm accrued 75 patients, and the chemotherapy-alone arm accrued 45 patients, with a weighted randomization to speed accrual. Fifty-three percent (64 of 120) had urothelial carcinoma, and 46.7% (56 of 120) had squamous cell carcinoma or other. The arms were balanced except for age (median, 52 vs 55 years; P = .04) and tumor size (mean, 4.9 vs 5.8 cm; P < .01), both favoring chemotherapy plus RT. Two-year outcomes and overall adjusted hazard ratios (HRs) for chemotherapy plus RT vs chemotherapy alone were 96% vs 69% (HR, 0.08; 95% CI, 0.02-0.39; P < .01) for LRFS, 68% vs 56% (HR, 0.53; 95% CI, 0.27-1.06; P = .07) for disease-free survival, and 71% vs 60% (HR, 0.61; 95% CI, 0.33-1.11; P = .11) for overall survival (OS). Five patients (7%) had RT associated late grade 3 gastrointestinal tract adverse effects in the chemotherapy plus RT arm. Conclusions and Relevance: Adjuvant chemotherapy plus RT was reasonably well tolerated and was associated with significant improvements in LRFS and marginal improvements in disease-free survival vs chemotherapy alone in LABC. The addition of adjuvant RT should be considered for LABC. This regimen warrants further study in phase 3 trials. Trial Registration: clinicaltrials.gov Identifier: NCT01734798. PMID- 29188296 TI - Association of Cerebral Amyloid-beta Aggregation With Cognitive Functioning in Persons Without Dementia. AB - Importance: Cerebral amyloid-beta aggregation is an early event in Alzheimer disease (AD). Understanding the association between amyloid aggregation and cognitive manifestation in persons without dementia is important for a better understanding of the course of AD and for the design of prevention trials. Objective: To investigate whether amyloid-beta aggregation is associated with cognitive functioning in persons without dementia. Design, Setting, and Participants: This cross-sectional study included 2908 participants with normal cognition and 4133 with mild cognitive impairment (MCI) from 53 studies in the multicenter Amyloid Biomarker Study. Normal cognition was defined as having no cognitive concerns for which medical help was sought and scores within the normal range on cognitive tests. Mild cognitive impairment was diagnosed according to published criteria. Study inclusion began in 2013 and is ongoing. Data analysis was performed in January 2017. Main Outcomes and Measures: Global cognitive performance as assessed by the Mini-Mental State Examination (MMSE) and episodic memory performance as assessed by a verbal word learning test. Amyloid aggregation was measured with positron emission tomography or cerebrospinal fluid biomarkers and dichotomized as negative (normal) or positive (abnormal) according to study-specific cutoffs. Generalized estimating equations were used to examine the association between amyloid aggregation and low cognitive scores (MMSE score <=27 or memory z score<=-1.28) and to assess whether this association was moderated by age, sex, educational level, or apolipoprotein E genotype. Results: Among 2908 persons with normal cognition (mean [SD] age, 67.4 [12.8] years), amyloid positivity was associated with low memory scores after age 70 years (mean difference in amyloid positive vs negative, 4% [95% CI, 0%-7%] at 72 years and 21% [95% CI, 10%-33%] at 90 years) but was not associated with low MMSE scores (mean difference, 3% [95% CI, -1% to 6%], P = .16). Among 4133 patients with MCI (mean [SD] age, 70.2 [8.5] years), amyloid positivity was associated with low memory (mean difference, 16% [95% CI, 12%-20%], P < .001) and low MMSE (mean difference, 14% [95% CI, 12%-17%], P < .001) scores, and this association decreased with age. Low cognitive scores had limited utility for screening of amyloid positivity in persons with normal cognition and those with MCI. In persons with normal cognition, the age-related increase in low memory score paralleled the age-related increase in amyloid positivity with an intervening period of 10 to 15 years. Conclusions and Relevance: Although low memory scores are an early marker of amyloid positivity, their value as a screening measure for early AD among persons without dementia is limited. PMID- 29188300 TI - Favorable versus unfavorable prognostic groups by post-chemoradiation FDG-PET imaging in node-positive esophageal squamous cell carcinoma patients treated with definitive chemoradiotherapy. AB - PURPOSE: Our purpose was to examine the prognostic value of post-CRT PET based on the presence or absence of FDG-avid metastatic lymph node(s) and metabolic response of the primary tumor in patients with clinically node-positive ESCC treated with definitive chemoradiotherapy (dCRT). METHODS: We identified 108 eligible patients treated by chemoradiotherapy (CRT) with or without resection from our prospectively collected database. Absence of FDG-avid metastatic lymph node with at least partial response of the primary tumor on PET scan after initial CRT was defined as the Post-CRT PET favorable group (yPET-F), and otherwise as unfavorable group (yPET-U). The Kaplan-Meier method and Cox regression were performed for survival analyses and multivariable analysis, respectively. RESULTS: The study cohort was comprised of 59 patients receiving dCRT. Forty-five patients receiving trimodality therapy (TMT) comprised the comparative group and four patients were excluded from further analyses for developing interval distant metastasis detected on post-CRT PET scan. The median follow-up for the study cohort was 41 months. On K-M analysis of the study cohort, yPET-F was found to have significantly better OS (2-year: 72.5% vs 13.7%, p < 0.01) and DMFS (2-year: 71.6% vs 36.6%, p = 0.01) than yPET-U. In multivariable analysis, yPET-F remained as a strong independent favorable prognosticator on both OS (HR 0.08, p < 0.01) and DMFS (HR 0.14, p = 0.02) for the dCRT cohort. Compared with TMT cohort, for yPET-U patients, TMT had better OS (p = 0.03) than dCRT-Operable and dCRT-Operable had superior OS (p = 0.04) than dCRT-Unresectable. For yPET-F patients, there was no difference in both OS (p > 0.99) and DMFS (p = 0.92) between these three groups. CONCLUSIONS: Absence of FDG avid metastatic lymph node with at least partial response of the primary tumor on PET scan after CRT (i.e., yPET-F status) prognosticate for excellent OS and DMFS in cN+ ESCC patients treated with dCRT, and might be comparable to TMT. PMID- 29188301 TI - Organic Amendments in a Long-term Field Trial-Consequences for the Bulk Soil Bacterial Community as Revealed by Network Analysis. AB - This study intended to elucidate the long-term effects of organic soil amendments on bacterial co-occurrence in bulk soil with and without addition of mineral fertiliser. Previous research mostly neglected the bacterial co-occurrence structure and focussed mainly on the parameters species diversity and abundance changes of species. Here we present a systematic comparison of two frequently used soil amendments, manure and straw, with regard to their impact on bacterial co-occurrence in a long-term field trial in Speyer, Germany. The approach involved 16S amplicon sequencing in combination with a bacterial network analysis, comparing the different fertiliser regimes. The results show an increase of bacterial diversity as well as an accumulation of bacteria of the order Bacillales in plots fertilised with manure compared to a control treatment. In the straw-amended plots neither an increase in diversity was found nor were indicative species detectable. Furthermore, network analysis revealed a clear impact of mineral fertiliser addition on bacterial co-occurrence structure. Most importantly, both organic amendments increased network complexity irrespective of mineral fertilisation regime. At the same time, the effects of manure and straw exhibited differences that might be explained by differences in their nutritional/chemical contents. It is concluded that bacterial interactions are a crucial parameter for the assessment of amendment effects regarding soil health and sustainability. PMID- 29188302 TI - Bamboo Specialists from Two Mammalian Orders (Primates, Carnivora) Share a High Number of Low-Abundance Gut Microbes. AB - Bamboo specialization is one of the most extreme examples of convergent herbivory, yet it is unclear how this specific high-fiber diet might selectively shape the composition of the gut microbiome compared to host phylogeny. To address these questions, we used deep sequencing to investigate the nature and comparative impact of phylogenetic and dietary selection for specific gut microbial membership in three bamboo specialists-the bamboo lemur (Hapalemur griseus, Primates: Lemuridae), giant panda (Ailuropoda melanoleuca, Carnivora: Ursidae), and red panda (Ailurus fulgens, Carnivora: Musteloideadae), as well as two phylogenetic controls-the ringtail lemur (Lemur catta) and the Asian black bear (Ursus thibetanus). We detected significantly higher Shannon diversity in the bamboo lemur (10.029) compared to both the giant panda (8.256; p = 0.0001936) and the red panda (6.484; p = 0.0000029). We also detected significantly enriched bacterial taxa that distinguished each species. Our results complement previous work in finding that phylogeny predominantly governs high-level microbiome community structure. However, we also find that 48 low-abundance OTUs are shared among bamboo specialists, compared to only 8 OTUs shared by the bamboo lemur and its sister species, the ringtail lemur (Lemur catta, a generalist). Our results suggest that deep sequencing is necessary to detect low-abundance bacterial OTUs, which may be specifically adapted to a high-fiber diet. These findings provide a more comprehensive framework for understanding the evolution and ecology of the microbiome as well as the host. PMID- 29188303 TI - Analysis of petrous apex meningocele associated with meningioma: is there any relation with chronic intracranial hypertension? AB - PURPOSE: Petrous apex meningocele (PAM) is an uncommon cystic lesion involving the petrous apex. The underlying cause of PAM may be related to chronic elevated intracranial pressure. The aim of the study was to explore the relationship between PAM and meningioma and between PAM and other intracranial hypertension findings. METHODS: Two hundred seventy-eight consecutive patients with meningiomas were retrospectively studied. Fifty age- and gender-matched controls were also enrolled in this study. The incidence of PAM, empty sella, tortuosity of the optic nerve, and hydrops of optic nerve sheath was evaluated. The maximum width, area, volume of each PAM, or Meckel's cave and volume of meningioma were measured in controls and patients, separately. RESULTS: One hundred fifty-nine (57.19%) patients were detected with coexistent PAMs. One hundred twenty-five patients had bilateral PAMs, 34 had unilateral lesions, and the remaining 119 did not have PAM. Two subjects (4/50) had unilateral PAMs in normal controls. The maximum width, area, volume of PAM, or Meckel's cave were significantly larger in the patients with bilateral PAM group than those in the unilateral PAM group, in the group without PAM, and those in control group (p = 0.000). The volume of meningioma was positively correlated with the PAM volume (r = 0.48). There was a positive correlation for the incidence between PAM and (1) empty sella (r = 0.901) and (2) tortuosity of the optic nerves and hydrops of the optic sheath (r = 0.825). CONCLUSION: Coexistence of PAMs with meningiomas is not rare in incidence, and it suggests a potential role for chronically elevated intracranial pressure and disturbance of CSF circulation in their pathophysiology. PMID- 29188304 TI - Diagnostic accuracy of CTA and MRI/MRA in the evaluation of the cortical venous reflux in the intracranial dural arteriovenous fistula DAVF. AB - PURPOSE: Computed tomography angiography (CTA) and magnetic resonance imaging/angiography (MRI/MRA) are used for the diagnosis of intracranial dural arteriovenous fistulas (DAVFs). The purpose of this study was to compare the diagnostic accuracy of CTA and magnetic resonance imaging/angiography (MRI/MRA) for detection of cortical venous reflux (CVR) in intracranial DAVFs. METHODS: The records of patients with angiography-confirmed intracranial DAVFs who also received CTA and MRI/MRA from January 2008 to July 2016 were reviewed. CTA and MRI/MRA were reviewed for signs of CVR, and the diagnostic accuracy of individual signs was evaluated by receiver operating curve (ROC) analysis. RESULTS: A total 108 patients were included in this study. CTA signs of CVR included abnormal dilatation, early enhancement, and the presence of a medullary or pial vein. MRI/MRA signs of CVR included abnormal dilatation, early enhancement, flow related enhancement, flow void, and medullary or pial venous collaterals. The sensitivity of individual CTA signs ranged from 62 to 96%, and specificities from 79 to 94%. The sensitivities of individual MRI/MRA signs ranged from 58 to 83%, and specificities from 77 to 93%. The area under ROC curve (AUC) of CTA and MRI/MRA were 0.91 and 0.87, respectively (P = 0.04 in direct comparison). In subgroup analysis, CTA had better diagnostic accuracy for higher grade disease (P = 0.05) and non-aggressive manifestation (P = 0.04). CONCLUSIONS: Both CTA and MRI/MRA have good diagnostic accuracy for detection of CVR in patients with intracranial DAVFs. There is modest evidence that CTA is better than MRI/MRA. PMID- 29188305 TI - Synergistic cytotoxicity of a prostate cancer-specific immunotoxin in combination with the BH3 mimetic ABT-737. AB - In many tumors, including prostate cancer, anti-apoptotic members of the Bcl-2 family are overexpressed and cause cell death resistance, which is a typical hallmark of cancer. Different therapeutic approaches, therefore, aim to restore the death mechanisms for enhanced apoptosis. Our recombinant immunotoxin D7(VL VH)-PE40 is composed of the scFv D7(VL-VH) against the prostate-specific membrane antigen (PSMA) on the surface of prostate cancer cells and of the cytotoxic domain of the bacterial toxin Pseudomonas Exotoxin A (PE40). Since Pseudomonas Exotoxin A-based immunotoxins are known to preferentially inhibit the expression of the anti-apoptotic protein Mcl-1, the rationale was to test our immunotoxin in combination with the BH3 mimetic ABT-737, which specifically inhibits Bcl-2, Bcl xl, and Bcl-w for enhanced induction of apoptosis in prostate cancer cells. The immunotoxin showed high and specific binding and cytotoxicity against PSMA expressing prostate cancer cells marked by a direct inhibition of Mcl-1. The combination of the immunotoxin with a subtoxic concentration of ABT-737 caused additive or even synergistic effects, which were based on an enhanced apoptosis induction as detected by poly(ADP-ribose) polymerase (PARP) and Caspase-3 cleavage in Western blot. Our study shows that the combination therapy of immunotoxin plus ABT-737 is a promising approach for the future treatment of advanced prostate cancer to improve therapeutic efficacy and to reduce adverse side effects. PMID- 29188307 TI - [Criteria for resectability of pancreatic cancer and postoperative imaging]. AB - By improving the techniques of pancreatic surgery, the mortality and morbidity for pancreatic carcinoma could be significantly reduced. For radiologists a profound knowledge of the surgical techniques is of decisive importance. Based on this knowledge postoperative complications can be reliably uncovered and local recurrences can be detected at an early stage. The complications resulting from pancreatic surgery can be severe and often necessitate a radiological intervention. As pancreatic cancer itself is a severe disease with a poor 5-year survival, which can only be improved by an R0 resection, it is crucial to identify using imaging those patients who are primarily operable or who can potentially achieve an operable condition through neoadjuvant chemotherapy (borderline) and inoperable patients to avoid postoperative complications which would additionally weaken them and result in unnecessary delays in initiating palliative therapy. Thus, familiarity with the clinical criteria of resectability and also inoperability in pancreatic cancer nowadays represents an essential basic knowledge for every oncological radiologist. PMID- 29188306 TI - Epidemiology, biology and therapy of Merkel cell carcinoma: conclusions from the EU project IMMOMEC. AB - Merkel cell carcinoma (MCC) is a highly aggressive, often lethal neuroendocrine cancer. Its carcinogenesis may be either caused by the clonal integration of the Merkel cell polyomavirus into the host genome or by UV-induced mutations. Notably, virally-encoded oncoproteins and UV-induced mutations affect comparable signaling pathways such as RB restriction of cell cycle progression or p53 inactivation. Despite its low incidence, MCC recently received much attention based on its exquisite immunogenicity and the resulting major success of immune modulating therapies. Here, we summarize current knowledge on epidemiology, biology and therapy of MCC as conclusion of the project 'Immune Modulating strategies for treatment of Merkel Cell Carcinoma', which was funded over a 5 year period by the European Commission to investigate innovative immunotherapies for MCC. PMID- 29188308 TI - Ureteroscopy from the recent past to the near future. AB - Stone surgery is one of oldest surgical practices undertaken by man. Hippocrates refused to let his followers "cut for the stone" and it was only in February 1980, when the first human trial of shock wave therapy on a renal stone was performed with success that a new era in minimally invasive treatment (surgery) for stones was opened up and this condemnation was finally resolved in the Hippocratic Oath. Endoscopy, using natural orifices, supported by anaesthesia, incremented by technology and with access to all points along the urinary tract, began by competing with ESWL, but is now the treatment of choice in most cases. As far as we know humans have always had stones. First, lithiasis was endemic bladder stones in children, now it is renal in general. Added to this a number of well-known risk factors, a rapid increase in obesity in the population, as well as bariatric surgery for its treatment, are causing an increase in the prevalence and recurrence of lithiasis everywhere. A short history of the advances made with the introduction and development of the ureteroscope, along with auxiliary devices, will show why this is the preferred technique at the moment for treating lithiasis in general and for treating stones in pregnant women, children and the obese in particular. Being a minimally invasive surgery, with a low morbidity and a very high efficiency and stonefree rate, has become established as a clear future technique for both adults and children. This development is not only due to technological advancements, but also to the routine use of the Holmium: YAG LASER for intracorporeal lithotripsy, capable of destroying any stone regardless of its composition or location, surpassing the ability of any other lithotripter. It is also due to the development of devices that allow access to the ureter and all parts of the kidney, as well as auxiliary aids to assist in the handling of stones during treatment. New LASERs, robotic control of the fdURS and digital imaging, as well as disposable devices, have had and, indeed, continue to have a unique impact on future development in this field. However, success will continue to depend on the careful choice of fURS, energy source and ancillary instruments obtained by the urologist during both real life and virtual training in human simulators. PMID- 29188309 TI - Optimization of ultrahigh-speed multiplex PCR for forensic analysis. AB - In this paper, we demonstrate the design and optimization of an ultrafast PCR amplification technique, used with a seven-locus multiplex that is compatible with conventional capillary electrophoresis systems as well as newer microfluidic chip devices. The procedure involves the use of a high-speed polymerase and a rapid cycling protocol to permit multiplex PCR amplification of forensic short tandem repeat loci in 6.5 min. We describe the selection and optimization of master mix reagents such as enzyme, buffer, MgCl2, and dNTPs, as well as primer ratios, total volume, and cycle conditions, in order to get the best profile in the shortest time possible. Sensitivity and reproducibility studies are also described. The amplification process utilizes a small high-speed thermocycler and compact laptop, making it portable and potentially useful for rapid, inexpensive on-site genotyping. The seven loci of the multiplex were taken from conventional STR genotyping kits and selected for their size and lack of overlap. Analysis was performed using conventional capillary electrophoresis and microfluidics with fluorescent detection. Overall, this technique provides a more rapid method for rapid sample screening of suspects and victims.

PMID- 29188311 TI - Differences by Veteran/civilian status and gender in associations between childhood adversity and alcohol and drug use disorders. AB - PURPOSE: To examine differences by US military Veteran status and gender in associations between childhood adversity and DSM-5 lifetime alcohol and drug use disorders (AUD/DUD). METHODS: We analyzed nationally representative data from 3119 Veterans (n = 379 women; n = 2740 men) and 33,182 civilians (n = 20,066 women; n = 13,116 men) as provided by the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III). We used weighted multinomial logistic regression, tested interaction terms, and calculated predicted probabilities by Veteran status and gender, controlling for covariates. To test which specific moderation contrasts were statistically significant, we conducted pairwise comparisons. RESULTS: Among civilians, women had lower AUD and DUD prevalence than men; however, with more childhood adversity, this gender gap narrowed for AUD and widened for DUD. Among Veterans, in contrast, similar proportions of women and men had AUD and DUD; with more childhood adversity, AUD predicted probability among men surpassed that of women. Childhood adversity elevated AUD probability among civilian women to levels exhibited by Veteran women. Among men, Veterans with more childhood adversity were more likely than civilians to have AUD, and less likely to have DUD. CONCLUSIONS: Childhood adversity alters the gender gap in AUD and DUD risk, and in ways that are different for Veterans compared with civilians. Department of Defense, Veterans Affairs, and community health centers can prevent and ameliorate the harmful effects of childhood adversity by adapting existing behavioral health efforts to be trauma informed, Veteran sensitive, and gender tailored. PMID- 29188310 TI - Untreated illness and recovery in clients of an early psychosis intervention program: a 10-year prospective cohort study. AB - PURPOSE: To investigate whether duration of untreated psychosis (DUP) and duration of untreated illness (DUI) are associated with measures of both subjective and objective recovery 10 years after a first episode of psychosis. METHODS: A cohort of 65 clients from an early psychosis intervention program completed a battery of outcome measures 10 years following initial treatment for first-episode psychosis (FEP). The outcomes of interest were self-perceived recovery scores (Maryland Assessment of Recovery in People with Serious Mental Illness Scale) and occupational activity, defined as engagement in work and/or school on a full/part-time basis. Multiple linear and logistic regression analyses were used to estimate the associations between DUP and DUI with each measure of recovery, adjusting for potential confounding factors. RESULTS: We did not find a statistically significant association between DUP and either occupational activity (OR = 1.26, 95% CI 0.81-1.95) or self-perceived recovery score (beta = - 0.73, 95% CI - 2.42 to 0.97). However, we found a significant negative association between DUI and self-perceived recovery score (beta = - 0.52, 95% CI - 0.87 to - 0.16). CONCLUSIONS: Our findings suggest that DUI may have a stronger influence than DUP on recovery from FEP at 10-year follow-up. This suggests the potential value in targeted interventions for people with a long DUI to increase the likelihood of achieving recovery after the first episode of psychosis. PMID- 29188312 TI - Physical therapists as first-line diagnosticians for traumatic acute rotator cuff tears: a prospective study. AB - BACKGROUND: Early diagnosis of traumatic acute full-thickness rotator cuff tears (FTRCT) is important to offer early surgical repair. Late repairs following fatty infiltration of the rotator cuff muscles have less favorable results. We think that physical therapists are valuable diagnosticians in a screening process. The objective of this study was to evaluate the usefulness of physical therapists as first-line diagnosticians in detecting acute traumatic FTRCT. METHODS: Between November 2010 and January 2014, 394 consecutive patients having an age between 18 and 75 years who sought medical care because of acute shoulder trauma with acute onset of pain, limited abduction and negative plain radiographs were included in the study. A clinical assessment was conducted by a physical therapist 1 week after the trauma. The patients were divided into three groups by the physical therapist according to the findings: FTRCT (Group I, n = 122); sprain (Group II, n = 62); or other specific diagnoses (Group III, n = 210). Group III patients were discharged and excluded from the study. Magnetic Resonance Imaging shoulder was performed for all Group I patients and for all patients with persistent symptoms in Group II. RESULTS: 79/184 patients had FTRCTs documented by MRI in groups I and II. The clinical assessment of the physical therapist had a sensitivity of 85%, specificity of 68%, and usefulness index of 0.45 (> 0.35 considered useful) for diagnosing FTRCT. CONCLUSION: Physical therapists can be useful as first-line diagnosticians in detecting traumatic FTRCT. PMID- 29188314 TI - The Effect of Cholesterol on the Dielectric Structure of Lipid Bilayers. AB - Cholesterol plays an important role in regulating the properties of phospholipid bilayers and many mechanisms have been proposed to explain why cholesterol is so ubiquitous within biological membranes of animals. Here we present the results of studies on the effect of cholesterol on the electrical/dielectric properties of lipid membranes tethered to a solid substrate. These tethered bilayer lipid membranes tBLM were formed on a commercially available chemically modified gold substrate. These lipid bilayers are very robust. Very high-resolution electrical impedance spectroscopy (EIS) was used to determine the dielectric structure of the lipid bilayers and associated interfaces. The EIS data allowed the dielectric substructure of the lipid bilayers to be determined. The results showed that when cholesterol was present in the tethered membranes at a concentration of 10% (mol/mol); the thickness of the tBLMs increased and the membrane conductance decreased. However, when cholesterol was present in the tethered membrane at more than 30% (mol/mol) the effect of cholesterol was dramatically different; the membranes then became thinner and possessed a much larger electrical conductance. The EIS allowed a distinction to be made between a hydrophobic region in the center of the bilayer and another hydrophobic region further out towards the polar head region, in addition to the polar head region itself. Cholesterol was found to have the largest effect on the inner, hydrophobic region, although the outer hydrophobic region was also affected.

AB - OBJECTIVES: Radiocephalic arteriovenous fistulas (RCAVF) are the preferred vascular access (VA) for hemodialysis (HD). Cohort studies from North America revealed that nonmaturation is a significant disadvantage of RCAVFs compared to other VAs. DESIGN: This present retrospective study describes the incidence of nonmaturation of AVFs and functional failure of arteriovenous grafts (AVG) in a multicentre cohort in the Netherlands and attempts to create a prediction model for nonmaturation of RCAVFs. Furthermore, the efficacy of interventions to promote maturation as well as the variability between hemodialysis centers was evaluated. MATERIALS: Medical records from 8 hospitals from 1997 to 2016 were retrospectively evaluated for VA type, maturation/primary success and demographics and comorbidities. METHODS: A prediction model was created for RCAVF nonmaturation using multivariate logistic regression analysis, selecting significant predictors using backward selection. Discrimination and calibration of the model were assessed. RESULTS: 1383 AVFs and 273 AVGs were included in 1221 patients. Overall nonmaturation was 24% for RCAVFs, and 11% for upper arm AVFs. The functional failure rate for AVGs was 6%. The nonmaturation rate of contralateral RCAVFs after failure of an RCAVF was 22%. Procedures to improve RCAVF maturation were successful in 98/142 cases (69%). Predictors for nonmaturation were female gender, peripheral vascular disease, cerebrovascular disease and a cephalic vein diameter <2.5 mm, but the prediction model lacked sensitivity and specificity predicting individual RCAVF nonmaturation (C statistic 0.629). CONCLUSION: Nonmaturation rates are highest for RCAVFs, but nonmaturation could not be predicted with demographic parameters.

AB - We retrospectively analyzed a large study to investigate the association of hepatitis B virus (HBV) with aggressive B cell non-Hodgkin's lymphoma (aggressive B-NHL) in China, where HBV is endemic. HBV was present in 39 aggressive B-NHL patients (10.46%), 13 indolent B-NHL patients (5.09%), 12 multiple myeloma (MM) patients (3.67%), and 5 solitary plasmacytoma (SP) patients (6.67%). HBV infection was significantly associated with increased risks for aggressive B-NHL (P < 0.01). HBV seems to have a very important role in the pathogenesis of aggressive B-NHL in China. PMID- 29188316 TI - Impact of Bicuspid Aortic Valve Morphology on Aortic Valve Disease and Aortic Dilation in Pediatric Patients. AB - Bicuspid aortic valve (BAV) is the most common congenital heart defect. BAV is associated with aortic stenosis and insufficiency, and aortic dilation in adult groups, but data in pediatric groups are limited. We sought to assess the impact of BAV morphology on aortic valve disease and aortic dilation in pediatric patients. We performed a retrospective review of all echocardiograms in patients with isolated BAV who were followed at our institution from July 2002 to July 2012. BAV morphology, aortic valve stenosis and/or insufficiency, and aortic dimensions were measured manually. Comparisons were made between right-left cusp fusion (RL) and right-noncoronary cusp fusion (RN) BAV morphologies. Generalized least square models were fit to analyze the impact of specific variables on aortic dilation. There were 1075 echocardiograms in 366 patients (72% male) with isolated BAV. Aortic valve insufficiency and stenosis were more common in RN (p < 0.001 for both). The median aortic sinus Z score was higher in the RL (0.47; IQR 0.31 to 1.44) than in the RN group (0.02; - 0.83 to 0.82) (p < 0.001). There was no difference in median ascending aorta Z score between groups. Patients with the highest weights had larger aortas (p < 0.001), but the absolute difference between the highest and lowest weight groups was small (1.5 mm). The impact of BAV morphology on aortic valve disease and aortic dilation in pediatric patients presages that seen in adults. Patient body weight does not make significant clinical impacts on aortic diameters, suggesting that Z scores for aortic diameters should be based on ideal body weights. PMID- 29188317 TI - Genetic Testing in Pediatric Cardiomyopathy. AB - Genetic testing is recommended in patients with dilated cardiomyopathy (DCM); however, limited studies demonstrate high yields of genetic testing in non hypertrophic (HCM) patients. Furthermore, there is sparse genotype-phenotype data in pediatric DCM patients. We performed a retrospective review of 70 consecutive probands with cardiomyopathy (non-HCM) who underwent genetic evaluation. Mean age at presentation was 5.48 years. Echocardiography revealed mean ejection fraction of 32.4%. The LVEDd z score ranged from - 5.7 to + 15.9. Cardiomyopathy was classified as dilated in 56, 10 with non-compaction, 2 with restrictive, and 2 with ARVC. TTN gene mutations were the most common gene involved. Genetic testing was negative in 16/70 (23%) giving a yield of 77% including VUS. 33% (23/70) of probands had a positive family history among whom the diagnostic yield was 57% (13/23) for pathogenic mutations. Yield for positive genetic testing in the DCM with positive family history group was 9/18 (50%). There were 6 deaths (9%) and 26/70 (37%) underwent transplantation. More frequent cardiac transplantations (48 vs. 34%) and deaths (17 vs. 2%) were seen in mutation-positive vs. mutation negative subgroups. This study demonstrates an increasing yield of genetic testing in DCM although with a high rate of VUS detection. Use of genetic information for better management and prognostication will require big data analysis. PMID- 29188318 TI - Myocardial Strain Using Cardiac MR Feature Tracking and Speckle Tracking Echocardiography in Duchenne Muscular Dystrophy Patients. AB - Duchenne muscular dystrophy (DMD) is an inherited X-linked disorder with an incidence of 1 in 3500 male births, and cardiomyopathy is becoming the leading cause of death. While Cardiac MRI (CMR) and late gadolinium enhancement (LGE) are important tools in recognizing myocardial involvement, myocardial strain imaging may demonstrate early changes and allow patients to avoid gadolinium contrast. We performed CMR feature tracking (FT) and echo-based speckle tracking (STE) strain measures on DMD patients and age/sex matched controls who had received a CMR with contrast and transthoracic echocardiogram. Data were collected for longitudinal strain in the apical four-chamber view and circumferential strain in the mid papillary parasternal short axis. Segmental wall analysis was performed and compared with the presence of LGE. Data were analyzed using student's t tests or one-way ANOVA adjusting for multiple comparisons. We measured 24 subjects with DMD and 8 controls. Thirteen of 24 DMD subjects were LGE positive only in the lateral segments in short-axis views. Average circumferential strain (CS) measured by FT was significantly decreased in DMD compared to controls (- 18.8 +/ 6.1 vs. - 25.5 +/- 3.2; p < 0.001) and showed significant differences in the anterolateral, inferolateral, and inferior segments. Average CS by STE trended towards significance (p = 0.06) but showed significance in only the inferior segment. FT showed significant differences in the inferolateral segment between LGE positive (- 15.5 +/- 9.0) and LGE negative (- 18.2 +/- 8.3) in DMD subjects compared to controls (- 28.6 +/- 7.3; p <= 0.04). FT also showed significant differences between anteroseptal and inferolateral segments within LGE-positive (p < 0.003) and LGE-negative (p < 0.03) DMD subjects while STE did not. There were no significant differences in longitudinal strain measures. CMR-FT-derived myocardial strain was able to demonstrate differences between subjects with DMD and controls not detected by STE. FT was also able to demonstrate differences in LGE-positive and LGE-negative segments within patients with DMD. FT may be able to predict LGE-positive segments in DMD without the use of gadolinium contrast. PMID- 29188319 TI - A dedicated paracentesis clinic decreases healthcare utilization for serial paracenteses in decompensated cirrhosis. AB - PURPOSE: The purpose of the study is to describe the effect of a dedicated paracentesis clinic on healthcare utilization by patients with decompensated cirrhosis and refractory ascites. METHODS: This Institutional Review Board approved retrospective study identified cirrhotic patients receiving paracenteses over a 6-month period before and after creating the paracentesis clinic. Patients were followed for 12 months to collect outcome data including characteristics of subsequent hospitalizations and paracenteses. Logistic regression was used to examine the association between the paracentesis clinic and outcomes. RESULTS: There were 183 patients and 1364 paracenteses performed during the study time period. Age, gender, cirrhosis etiology, MELD, Child-Pugh, and Charlson comorbidity index were comparable between the two groups. Rates of mortality, transplant, and hospitalization were also similar during 1 year follow-up. After establishment of the paracentesis clinic, median paracenteses per patient increased from 2 (IQR 1-7) to 4 (IQR 2-11) (P = 0.01); albumin replacement after paracenteses >= 5 L improved from 76.3% to 91.7% (P < 0.001); and the fraction of outpatient paracenteses performed in the emergency department decreased from 13.4% to 3.8% (P < 0.001). Major complications remained negligible at 0.81% across both time periods. While fewer patients were admitted for ascites after the paracentesis clinic (39.6% vs. 20.8%, P = 0.009), more patients had acute kidney injury (AKI) during follow-up (47.2% vs. 65.9%, P = 0.02), with a trend towards more AKI admissions (22.6% vs. 35.4%, P = 0.09). CONCLUSION: A dedicated paracentesis clinic can improve access and wait times, while also reducing admissions for ascites and paracenteses performed in the emergency department. PMID- 29188320 TI - Characterization of a New Ezakiella Isolated from the Human Vagina: Genome Sequence and Description of Ezakiella massiliensis sp. nov. AB - The study of the vaginal microbiota using the "culturomics concept" allowed us to isolate, from the vaginal swab of an asymptomatic 20-year-old woman who had sexual relations with another woman with bacterial vaginosis, an unknown Gram positive anaerobic coccus-shaped bacterium that was designated strain Marseille P2951T and characterized using taxono-genomics. Strain Marseille-P2951T is non motile and non-spore forming and exhibits catalase and oxidase activities. Its 16S rRNA gene-based identification showed 98.5% identity with Ezakiella peruensis, the phylogenetically closest species. The major fatty acids are C18:1n9 (58%) and C16:0 (22%). With a 1,741,785 bp length, the G+C content of the genome is 36.69%. Of a total of 1657 genes, 1606 are protein-coding genes and 51 RNAs. Also, 1123 genes are assigned a putative function and 127 are ORFans. Phenotypic, phylogenetic, and genomics analyses revealed that strain Marseille P2951T (=CSUR P2951 =DSM 103122) is distinct and represents a new species of the genus Ezakiella, for which the name Ezakiella massiliensis sp. nov. is proposed. PMID- 29188322 TI - Mass balance, metabolic disposition, and pharmacokinetics of a single oral dose of regorafenib in healthy human subjects. AB - PURPOSE: To evaluate the mass balance, metabolic disposition, and pharmacokinetics of a single dose of regorafenib in healthy volunteers. In addition, in vitro metabolism of regorafenib in human hepatocytes was investigated. METHODS: Four healthy male subjects received one 120 mg oral dose of regorafenib containing approximately 100 uCi (3.7 MBq) [14C]regorafenib. Plasma concentrations of parent drug were derived from HPLC-MS/MS analysis and total radioactivity from liquid scintillation counting (LSC). Radiocarbon analyses used HPLC with fraction collection followed by LSC for all urine samples, plasma, and fecal homogenate extracts. For the in vitro study, [14C]regorafenib was incubated with human hepatocytes and analyzed using HPLC-LSC and HPLC-HRMS/MS. RESULTS: Regorafenib was the major component in plasma, while metabolite M-2 (pyridine N-oxide) was the most prominent metabolite. Metabolites M-5 (demethylated pyridine N-oxide) and M-7 (N-glucuronide) were identified as minor plasma components. The mean concentration of total radioactivity in plasma/whole blood appeared to plateau at 1-4 h and again at 6-24 h post-dose. In total, 90.5% of administered radioactivity was recovered in the excreta within a collection interval of 12 days, most of which (71.2%) was eliminated in feces, while excretion via urine accounted for 19.3%. Regorafenib (47.2%) was the most prominent component in feces and was not excreted into urine. Excreted metabolites resulted from oxidative metabolism and glucuronidation. CONCLUSIONS: Regorafenib was eliminated predominantly in feces as well as by hepatic biotransformation. The multiple biotransformation pathways of regorafenib decrease the risk of pharmacokinetic drug-drug interactions. PMID- 29188321 TI - Comparative Analyses of Methanogenic and Methanotrophic Communities Between Two Different Water Regimes in Controlled Wetlands on the Qinghai-Tibetan Plateau, China. AB - Wetlands are an important methane (CH4) emission source. CH4 is mainly produced during the biogeochemical process, in which methanogens and methanotrophs both play important roles. However, little is known how these two microbial communities change under different water regimes. In this study, the diversity and abundance of methanogens and methanotrophs in wetlands on Qinghai-Tibetan Plateau with different water contents (a high water content site DZ2-14-3 and a low water content site DZ2-14-4) were studied by using phylogenetic analysis and quantitative PCR based on mcrA gene and pmoA gene. A total of 16 methanogenic operational taxonomic units (OTUs) and 9 methanotrophic OTUs are obtained. For methanogens, Fen cluster (58.0%) and Methanosaetaceae (20.3%) are the dominant groups in high moisture samples, whereas Methanosaetaceae (32.4%), Methanosarcinaceae (29.4%), and Methanobacteriaceae (22.1%) are prevalent in low moisture samples. Methylobacter (90.0%) of type I methanotrophs are overwhelmingly dominant in high moisture samples, while Methylocystis (53.3%) and Methylomonas (42.2%) belonging to types II and I methanotrophs are the predominant groups in low moisture samples. Furthermore, qPCR analysis revealed that the abundance of methanogens and methanotrophs were higher in high moisture samples than that in low moisture samples. Overall, this comparative study between wetlands controlled by two different water regimes on the Qinghai-Tibetan Plateau provides fundamental data for further research on microbial functions within extreme ecosystems. PMID- 29188323 TI - Evolution of social media: review of the role of podcasts in gynaecology. AB - Podcasts are an emerging social media phenomenon in medicine, originating from critical care specialities and now expanding to other domains. Aided by the rapid increase in popularity of social media platforms and the advantage of accessibility, universality and portability, there has been a slow but significant expansion of podcast use in gynaecology. Current literature suggests that there is potential for digital communication to enhance dissemination of information, however there is conflicting evidence on its ability to increase users' knowledge. Emerging interest in urogynaecology presents an opportunity for the subspeciality to tailor podcasts to the needs of its users. In this review, the origins, current evidence and future trends in the use of podcasts in urogynaecology are explored. PMID- 29188324 TI - Total vaginectomy and urethral lengthening at time of neourethral prelamination in transgender men. AB - INTRODUCTION AND HYPOTHESIS: For transgender men (TGM), gender-affirmation surgery (GAS) is often the final stage of their gender transition. GAS involves creating a neophallus, typically using tissue remote from the genital region, such as radial forearm free-flap phalloplasty. Essential to this process is vaginectomy. Complexity of vaginal fascial attachments, atrophy due to testosterone use, and need to preserve integrity of the vaginal epithelium for tissue rearrangement add to the intricacy of the procedure during GAS. We designed the technique presented here to minimize complications and contribute to overall success of the phalloplasty procedure. METHODS: After obtaining approval from the Institutional Review Board, our transgender (TG) database at the University of Miami Hospital was reviewed to identify cases with vaginectomy and urethral elongation performed at the time of radial forearm free-flap phalloplasty prelamination. Surgical technique for posterior vaginectomy and anterior vaginal wall-flap harvest with subsequent urethral lengthening is detailed. RESULTS: Six patients underwent total vaginectomy and urethral elongation at the time of radial forearm free-flap phalloplasty prelamination. Mean estimated blood loss (EBL) was 290 +/- 199.4 ml for the vaginectomy and urethral elongation, and no one required transfusion. There were no intraoperative complications (cystotomy, ureteral obstruction, enterotomy, proctotomy, or neurological injury). One patient had a urologic complication (urethral stricture) in the neobulbar urethra. CONCLUSIONS: Total vaginectomy and urethral lengthening procedures at the time of GAS are relatively safe procedures, and using the described technique provides excellent tissue for urethral prelamination and a low complication rate in both the short and long term. PMID- 29188326 TI - Bioavailability of Metsulfuron and Sulfentrazone Herbicides in Soil as Affected by Amendment with Two Contrasting Willow Biochars. AB - This study investigated the effect of two willow (Salix spp.) biochars, produced using either fast- or slow-pyrolysis, on the bioavailability of metsulfuron and sulfentrazone herbicides in soil. Five rates (0%, 1%, 2%, 3%, and 4%; w/w) of each biochar were used, along with varying rates of metsulfuron (0-3.2 ug ai kg 1) and sulfentrazone (0-200 ug ai kg-1), followed by a sugar beet bioassay. The fast-pyrolysis biochar had minimal effect, while the slow-pyrolysis biochar decreased the bioavailability of both herbicides. Despite using the same feedstock, the two biochars had different physical and chemical properties, of which specific surface area was most contrasting (3.0 and 175 m2 g-1 for fast- and slow-pyrolysis biochar, respectively). Increased anionic herbicide adsorption associated with greater surface area of the slow-pyrolysis biochar is considered to be the primary mechanism responsible for reducing herbicide bioavailability with this biochar. PMID- 29188325 TI - Pregnancy impact on uterosacral ligament and pelvic muscles using a 3D numerical and finite element model: preliminary results. AB - INTRODUCTION AND HYPOTHESIS: We studied the geometry of and changes in structures that play an important role in stabilizing the pelvic system during pregnancy using a numerical system at different gestational ages and postpartum. METHODS: We developed a parturient numerical model to assess pelvic structures at different gestational stages (16, 32, and 38 weeks) and postpartum (2 months and 1 year) using magnetic resonance imaging (MRI). Organs, muscles, and ligaments were segmented to generate a 3D model of the pelvis. We studied changes in the length of uterosacral ligaments (USL) and thickness of the puborectal portion of the levator ani muscle (LAM) during and after pregnancy. We used this model to perform finite element (FE) simulation and analyze deformations of these structures under stress from the increase in uterine weight. RESULTS: Analysis reveals an increase in the length of US ligaments at 16, 32, and 38 weeks. Two months after delivery, it decreases without returning to the length at 16 weeks of pregnancy. Similar changes were observed for the puborectal portion of the LAM. Variations observed in these structures are not equivalent to other anatomical structures of pelvic suspension. FE simulation with increased uterus weight does not lead to those findings. CONCLUSION: This analysis brings new elements and a new focus for discussion relating to changes in pelvic balance of parturient women that are not simply linked to the increase in uterine volume.

AB - Mercury concentrations were measured in eggs, larvae, and adult spawning-phase sea lampreys (Petromyzon marinus) collected in tributaries of Lake Superior to investigate spatial and ontogenetic variation. There were significant differences in mercury concentrations between all three life stages, with levels highest in adults (mean = 3.01 ug/g), followed by eggs (mean = 0.942 ug/g), and lowest in larvae (mean = 0.455 ug/g). There were no significant differences in mercury concentrations by location for any life stage or by sex in adults. Mercury was not correlated with adult or larval lamprey length or mass. Mercury levels in adult lampreys exceeded U.S. and Canadian federal guidelines for human consumption. Mercury concentrations in all life stages exceeded criteria for the protection of piscivorous wildlife, posing a threat to local fish, birds, and mammals. High mercury levels in adult lampreys combined with their semelparous life history make them a potential source of lake-derived mercury to spawning streams. PMID- 29188328 TI - Hydrocarbon Degradation and Lead Solubility in a Soil Polluted with Lead and Used Motor Oil Treated by Composting and Phytoremediation. AB - Used lubricant oils and metals can be common soil pollutants in abandoned sites. When soil is contaminated with various hazardous wastes, the efficiency of biological treatments could be affected. The purpose of this work was to investigate the effect of combining phytoremediation and composting on the efficiency of hydrocarbon degradation and lead solubility in a soil contaminated with 31,823 mg/kg of total petroleum hydrocarbon (TPH) from used motor oil and 8260 mg/kg of lead. Mexican cactus (Opuntia ficus indica) and yard trimmings were added in the composting process, and lucerne (Medicago sativa) was used in the phytoremediation process. After a 9 week composting process, only 13% of the initial TPH concentration was removed. The following 20 week phytoremediation process removed 48% of TPH. The highest TPH degradation percentage (66%), was observed in the experiment with phytoremediation only. This work demonstrates sustainable technologies, such as biological treatments, represent low-cost options for remediation; however, they are not frequently used because they require long periods of time for success. PMID- 29188329 TI - Water Quality and Management Changes Over the History of Poland. AB - Poland is one of the countries distinguished by a long and colorful past. Undergoing numerous turbulent socio-economic changes forced by the course of history, Poland is now one of the member states of the European Union. Experiencing low water quantity and high contamination levels in surface waters, Poland is following other EU countries in the effort to reach a "good" water status. Herein are presented impacts of changes in Polish history on water legislation, management, and research, as well as explanations for the perceptible split between engineering and scientific approaches to the aquatic issues. Drawbacks caused by unsatisfactory state research funding for the sciences and division of the water related contemporary scientific interests are also discussed. PMID- 29188330 TI - Metabolic pathway of 6-aminohexanoate in the nylon oligomer-degrading bacterium Arthrobacter sp. KI72: identification of the enzymes responsible for the conversion of 6-aminohexanoate to adipate. AB - Arthrobacter sp. strain KI72 grows on a 6-aminohexanoate oligomer, which is a by product of nylon-6 manufacturing, as a sole source of carbon and nitrogen. We cloned the two genes, nylD 1 and nylE 1 , responsible for 6-aminohexanoate metabolism on the basis of the draft genomic DNA sequence of strain KI72. We amplified the DNA fragments that encode these genes by polymerase chain reaction using a synthetic primer DNA homologous to the 4-aminobutyrate metabolic enzymes. We inserted the amplified DNA fragments into the expression vector pColdI in Escherichia coli, purified the His-tagged enzymes to homogeneity, and performed biochemical studies. We confirmed that 6-aminohexanoate aminotransferase (NylD1) catalyzes the reaction of 6-aminohexanoate to adipate semialdehyde using alpha ketoglutarate, pyruvate, and glyoxylate as amino acceptors, generating glutamate, alanine, and glycine, respectively. The reaction requires pyridoxal phosphate (PLP) as a cofactor. For further metabolism, adipate semialdehyde dehydrogenase (NylE1) catalyzes the oxidative reaction of adipate semialdehyde to adipate using NADP+ as a cofactor. Phylogenic analysis revealed that NylD1 should be placed in a branch of the PLP-dependent aminotransferase sub III, while NylE1 should be in a branch of the aldehyde dehydrogenase superfamily. In addition, we established a NylD1/NylE1 coupled system to quantify the aminotransferase activity and to enable the conversion of 6-aminohexaoate to adipate via adipate semialdehyde with a yield of > 90%. In the present study, we demonstrate that 6-aminohexanoate produced from polymeric nylon-6 and nylon oligomers (i.e., a mixture of 6 aminohexaoate oligomers) by nylon hydrolase (NylC) and 6-aminohexanoate dimer hydrolase (NylB) reactions are sequentially converted to adipate by metabolic engineering technology. PMID- 29188331 TI - A type D ferulic acid esterase from Streptomyces werraensis affects the volume of wheat dough pastries. AB - A type D ferulic acid esterase (FAE) was identified in the culture supernatant of Streptomyces werraensis, purified, sequenced, and heterologously produced in E. coli BL21(DE3)Star by co-expressing chaperones groES-groEL (69 U L-1). The unique enzyme with a mass of about 48 kDa showed no similarity to other FAEs, and only moderate homology (78.5%) to a Streptomycete beta-xylosidase. The purified reSwFAED exhibited a temperature optimum of 40 degrees C, a pH optimum in the range from pH seven to eight and a clear preference for bulky natural substrates, such as 5-O-trans-feruloyl-L-arabinofuranose (FA) and beta-D-xylopyranosyl-(1->2) 5-O-trans-feruloyl-L-arabinofuranose (FAX), compared to the synthetic standard substrate methyl ferulate. Treatment of wheat dough with as little as 0.03 U or 0.3 U kg-1 reSwFAED activity resulted in a significant increase of the bun volume (8.0 or 9.7%, resp.) after baking when combined with polysaccharide-degrading enzymes from Aspergillus. For the first time, the long-standing, but rarely proven positive effect of a FAE in baking was confirmed. PMID- 29188333 TI - Dynamically tensioned ACL functional knee braces reduce ACL and meniscal strain. AB - PURPOSE: The effectiveness of ACL functional knee braces to reduce meniscal and ACL strain after ACL injury or reconstruction is not well understood. A new dynamic knee tensioning brace system has been designed to apply an active stabilizing force to the knee. The ability of this system to reduce tissue strains is unknown. The purpose of this study was to test the ability of the dynamically tensioned brace to reduce strain in both the ACL and meniscus during rehabilitation activities. METHODS: A combined in vivo/in silico/in vitro method was used to study three activities: gait, double leg squat, and single leg squat. Muscle forces and kinematics for each activity were derived through in vivo motion capture and applied to seven cadaveric knee specimens fitted with custom braces. Medial meniscal strain and ACL strain were measured in ACL intact, deficient and reconstructed conditions. RESULTS: The brace lowered peak and average meniscal strain in ACL deficient knees (P < 0.05) by an average of 1.7%. The brace was also found to lower meniscal strain in reconstructed knees (1.1%) and lower ACL strain in ACL intact (1.3%) and reconstructed knees (1.4%) (P < 0.05). CONCLUSIONS: This study supports the use of a brace equipped with a dynamic tensioning system to lower meniscal strain in ACL-deficient knees. Its use may help decrease the risk of subsequent meniscal tears in chronic ACL deficiency or delayed reconstruction. In ACL-intact and reconstructed knees, the brace may be beneficial in injury prophylaxis or in protecting the ACL graft following reconstruction. These results will aid clinicians make informed recommendations for functional brace use in patients with unstable knees. LEVEL OF EVIDENCE: II. PMID- 29188332 TI - "I never made it to the pros..." Return to sport and becoming an elite athlete after pediatric and adolescent anterior cruciate ligament injury-Current evidence and future directions. AB - The management of anterior cruciate ligament (ACL) injuries in the skeletally immature and adolescent patient remains an area of controversy in sports medicine. This study, therefore, summarizes and discusses the current evidence related to treating pediatric and adolescent patients who sustain an ACL injury. The current literature identifies a trend towards ACL reconstruction as the preferred treatment option for ACL injuries in the young, largely justified by the risk of further structural damage to the knee joint. Worryingly, a second ACL injury is all too common in the younger population, where almost one in every three to four young patients who sustain an ACL injury and return to high-risk pivoting sport will go on to sustain another ACL injury. The clinical experience of these patients emphasizes the rarity of an athlete who makes it to elite level after a pediatric or adolescent ACL injury, with or without reconstruction. If these patients are unable to make it to an elite level of sport, treatment should possibly be modified to take account of the risks associated with returning to pivoting and strenuous sport. The surveillance of young athletes may be beneficial when it comes to reducing injuries. Further research is crucial to better understand specific risk factors in the young and to establish independent structures to allow for unbiased decision-making for a safe return to sport after ACL injury. Level of evidence V. PMID- 29188334 TI - Increased in vivo patellofemoral loading after total knee arthroplasty in resurfaced patellae. AB - PURPOSE: The primary purpose of the study was to investigate if and how patellar bone tracer uptake (BTU) distribution in SPECT/CT is influenced by patellar resurfacing and the position of femoral and tibial TKA component position. METHODS: A total of 104 knees of 103 consecutive patients who underwent primary TKA were prospectively investigated. Primary patellar resurfacing was done in 40 knees while 64 had a TKA without patellar resurfacing. All patients underwent clinical assessment using the knee society score (KSS) and standardized radiographs and Tc-99m-HDP-SPECT/CT before and 12 and 24 months after TKA. Measurements of BTU including intensity and anatomical distribution pattern in eight different patellar regions were performed. Tibial and femoral TKA component position was assessed from 3D reconstructed CT data. Patellar height, thickness and tilt were measured and the distance between the tibial tuberosity and the trochlear groove (TT-TG) was measured. Univariate analysis was performed to identify differences between the two groups (p < 0.05). RESULTS: Significantly higher BTU was found in the anterior, non-articular, areas of the patella in patients who underwent patellar resurfacing (p < 0.05). The BTU pattern was similar between the groups, as the maximal uptake in both groups was seen in the superior posterior parts and the minimal uptake was seen in the inferior anterior parts. The mean postoperative KSS was significantly higher in the unresurfaced group after 12 months (p < 0.05), but with no significant difference after 24 months. CONCLUSIONS: Based on the findings of the present study, patellar resurfacing is related to significantly higher BTU in the anterior parts of the patella and lower clinical outcomes. In light of these results, routine patellar resurfacing as part of a primary TKA might be reevaluated. SPECT/CT enables a precise localization of the BTU and might be considered as the ideal imaging modality for evaluation and investigate of patellofemoral disorders after TKA. PMID- 29188335 TI - Poly-traumatic multi-ligament knee injuries: is the knee the limiting factor? AB - PURPOSE: Multi-ligament knee injuries (MLKI) from a high-velocity accident are rare but potentially devastating. This matched cohort analysis compares knee functional outcomes after multiple ligament reconstruction in poly-trauma patients to those that occurred in isolation. METHODS: Sixty-two patients with MLKI that occurred either as a component of polytrauma or had occurred in isolation were matched according to age, sex, and knee dislocation grade. Functional outcomes and knee physical examination were assessed at a 2-year follow-up. New Injury Severity Score (NISS) was calculated based on the poly traumatic injury pattern. Risk factors for worse outcomes in the poly-trauma cohort were analyzed. RESULTS: The mean IKDC, Lysholm, and NISS scores in the polytrauma cohort were 57.2 +/- 21.9, 62 +/- 22, and 40.9 +/- 20.4, respectively, at a mean of 67 months (range 24-220). The isolated knee injury group was followed for a mean of 74 months (range 24-266) with mean IKDC and Lysholm scores of 71.1 +/- 26.5 and 78 +/- 23, respectively. Patients in the control cohort had significantly higher IKDC (p = 0.01) and Lysholm scores, (p = 0.003). There were no major differences between the two groups in regards physical examination findings at final follow-up. None of the analyzed risk factors was predictive of poor outcome. CONCLUSION: When comparing knees with similar multi-ligament and neurovascular injury patterns, patients who sustained their injury as a result of poly-trauma demonstrated significantly lower functional scores following reconstruction. This is despite restoration of similar knee stability and range of motion. The functional outcomes following MLKI reconstruction in poly traumatized patients are influenced by factors other than the knee including concomitant injuries and psychosocial factors. LEVEL OF EVIDENCE: Therapeutic Level III. PMID- 29188336 TI - No risk of arthrofibrosis after acute anterior cruciate ligament reconstruction. AB - PURPOSE: To compare acute ACL reconstruction (ACLR) within 8 days of injury with delayed reconstruction after normalized range of motion (ROM), 6-10 weeks after injury. It was hypothesized that acute ACL reconstruction with modern techniques is safe and can be beneficial in terms of patient-reported outcomes and range of motion. METHODS: Sample size calculation indicated 64 patients would be required to find a 5 degrees difference in ROM at 3 months. Seventy patients with high recreational activity level, Tegner level 6 or more, were randomized to acute (within 8 days) or delayed (6-10 weeks) ACLR between 2006 and 2013. During the first 3 months following surgery patients were contacted weekly by SMS and asked 'How is your knee functioning?', with answers given on a Visual-Analog Scale (0 10). ROM was assessed after 3 months by the rehab physiotherapist. Patient reported outcomes, objective IKDC and manual stability measurements were collected by an independent physiotherapist not involved in the rehab at the 6 month follow-up. RESULTS: At 3-month follow-up, 91% of the patients were assessed with no significant differences in flexion, extension or total ROM demonstrated between groups. At the 6-month follow-up, the acute group had significantly less muscle atrophy of the thigh muscle compared to the contralateral leg. Furthermore, a significantly higher proportion of patients in the acute group passed or were close to passing the one leg hop test (47 versus 21%, p = 0.009). No difference was found between the groups in the other clinical assessments. Additionally, no significant difference between the groups was found in terms of associated injuries. CONCLUSION: Acute ACLR within 8 days of injury does not appear to adversely affect ROM or result in increased stiffness in the knee joint when compared to delayed surgery. LEVEL OF EVIDENCE: II.

AB - The authors regret that Nish Chaturvedi's name was spelt incorrectly in the author list. The details given in this correction are correct. PMID- 29188338 TI - Effects of hypoglycaemia on working memory and regional cerebral blood flow in type 1 diabetes: a randomised, crossover trial. AB - AIMS/HYPOTHESIS: The aim of this randomised, crossover trial was to compare cognitive functioning and associated brain activation patterns during hypoglycaemia (plasma glucose [PG] just below 3.1 mmol/l) and euglycaemia in individuals with type 1 diabetes mellitus. METHODS: In this patient-blinded, crossover study, 26 participants with type 1 diabetes mellitus attended two randomised experimental visits: one hypoglycaemic clamp (PG 2.8 +/- 0.2 mmol/l, approximate duration 55 min) and one euglycaemic clamp (PG 5.5 mmol/l +/- 10%). PG levels were maintained by hyperinsulinaemic glucose clamping. Cognitive functioning was assessed during hypoglycaemia and euglycaemia conditions using a modified version of the digit symbol substitution test (mDSST) and control DSST (cDSST). Simultaneously, regional cerebral blood flow (rCBF) was measured in pre specified brain regions by six H215O-positron emission tomographies (PET) per session. RESULTS: Working memory was impaired during hypoglycaemia as indicated by a statistically significantly lower mDSST score (estimated treatment difference [ETD] -0.63 [95% CI -1.13, -0.14], p = 0.014) and a statistically significantly longer response time (ETD 2.86 s [7%] [95% CI 0.67, 5.05], p = 0.013) compared with euglycaemia. During hypoglycaemia, mDSST task performance was associated with increased activity in the frontal lobe regions, superior parietal lobe and thalamus, and decreased activity in the temporal lobe regions (p < 0.05). Working memory activation (mDSST - cDSST) statistically significantly increased blood flow in the striatum during hypoglycaemia (ETD 0.0374% [95% CI 0.0157, 0.0590], p = 0.002). CONCLUSIONS/INTERPRETATION: During hypoglycaemia (mean PG 2.9 mmol/l), working memory performance was impaired. Altered performance was associated with significantly increased blood flow in the striatum, a part of the basal ganglia implicated in regulating motor functions, memory, language and emotion.

PMID- 29188341 TI - A review of metabolic potential of human gut microbiome in human nutrition. AB - The human gut contains a plethora of microbes, providing a platform for metabolic interaction between the host and microbiota. Metabolites produced by the gut microbiota act as a link between gut microbiota and its host. These metabolites act as messengers having the capacity to alter the gut microbiota. Recent advances in the characterization of the gut microbiota and its symbiotic relationship with the host have provided a platform to decode metabolic interactions. The human gut microbiota, a crucial component for dietary metabolism, is shaped by the genetic, epigenetic and dietary factors. The metabolic potential of gut microbiota explains its significance in host health and diseases. The knowledge of interactions between microbiota and host metabolism, as well as modification of microbial ecology, is really beneficial to have effective therapeutic treatments for many diet-related diseases in near future. This review cumulates the information to map the role of human gut microbiota in dietary component metabolism, the role of gut microbes derived metabolites in human health and host-microbe metabolic interactions in health and diseases.

AB - AIMS/HYPOTHESIS: Substantial weight loss in type 2 diabetes can achieve a return to non-diabetic biochemical status, without the need for medication. The Diabetes Remission Clinical Trial (DiRECT), a cluster-randomised controlled trial, is testing a structured intervention designed to achieve and sustain this over 2 years in a primary care setting to determine practicability for routine clinical practice. This paper reports the characteristics of the baseline cohort. METHODS: People with type 2 diabetes for <6 years with a BMI of 27-45 kg/m2 were recruited in 49 UK primary care practices, randomised to either best-practice diabetes care alone or with an additional evidence-based weight management programme (Counterweight-Plus). The co-primary outcomes, at 12 months, are weight loss >=15 kg and diabetes remission (HbA1c <48 mmol/mol [6.5%]) without glucose-lowering therapy for at least 2 months. Outcome assessors are blinded to group assignment. RESULTS: Of 1510 people invited, 423 (28%) accepted; of whom, 306 (72%) were eligible at screening and gave informed consent. Seven participants were later found to have been randomised in error and one withdrew consent, leaving 298 (176 men, 122 women) who will form the intention to treat (ITT) population for analysis. Mean (SD) age was 54.4 (7.6) years, duration of diabetes 3.0 (1.7) years, BMI 34.6 (4.4) kg/m2 for all participants (34.2 (4.2) kg/m2 in men and 35.3 (4.6) kg/m2 in women) and baseline HbA1c (on treatment) 59.3 (12.7) mmol/mol (7.6% [1.2%]). The recruitment rate in the intervention and control groups, and comparisons between the subgroups recruited in Scotland and England, showed few differences. CONCLUSIONS/INTERPRETATION: DiRECT has recruited a cohort of people with type 2 diabetes with characteristics similar to those seen in routine practice, indicating potential widespread applicability. Over 25% of the eligible population wished to participate in the study, including a high proportion of men, in line with the prevalence distribution of type 2 diabetes.

AB - A Gram-negative, non-motile, rod-shaped, aerobic bacterial strain, designated S2 3-6T, was isolated from soil in Jeollabuk-do province, South Korea, and was characterized taxonomically using a polyphasic approach. According to a comparative 16S rRNA gene sequence analysis, strain S2-3-6T belonged to the family Cytophagaceae and was most closely related to Spirosoma endophyticum EX36T (98.2%), Spirosoma fluviale MSd3T (96.0%), and Spirosoma linguale DSM 74T (95.7%). Strain S2-3-6T contained summed feature 3 (C16:1 omega7c/C16:1 omega6c), C16:1 omega5c, and C16:0 N alcohol as major cellular fatty acids, MK-7 as the predominant respiratory quinone, and phosphatidylethanolamine as the main polar lipid. The DNA G+C content of strain S2-3-6T was 47.8%. Phenotypic and chemotaxonomic data supported the affiliation of strain S2-3-6T to the genus Spirosoma. However, the DNA-DNA relatedness between strain S2-3-6T and Spirosoma endophyticum KACC 17920T was 27%, clearly showing that the isolate constitutes a new genospecies. Strain S2-3-6T could be clearly differentiated from its closest neighbors based on its phenotypic, genotypic, and chemotaxonomic features. Therefore, strain S2-3-6T represents a novel species of the genus Spirosoma, for which the name Spirosoma jeollabukense sp. nov. is proposed. The type strain is S2-3-6T (= KCTC 52725T = JCM 32129T). PMID- 29188343 TI - Lysobacter tongrenensis sp. nov., isolated from soil of a manganese factory. AB - A Gram-staining negative, aerobic, non-motile, rod-shaped bacterial strain, designated YS-37T, was isolated from soil in a manganese factory, People's Republic of China. Based on16S rRNA gene sequence analysis, strain YS-37T was most closely related to Lysobacter pocheonensis Gsoil 193T (97.0%), Lysobacter dokdonensis DS-58T (96.0%) and Lysobacter daecheongensis Dae08T (95.8%) and grouped together with L. pocheonensis Gsoil 193T and Lysobacter dokdonensis DS 58T. The DNA-DNA hybridization value between strain YS-37T and L. pocheonensis KCTC 12624T was 43.3% (+/- 1). The major respiratory quinone of strain YS-37T was ubiquinone-8, and the polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phospholipid, phosphatidylmethylethaolamine and two unknown lipids. Its major cellular fatty acids (> 5%) were iso-C15:0, iso-C17:1 omega9c, iso-C16:0, iso-C11:0 3-OH and iso C11:0 and the G + C content of the genomic DNA was 67.1 mol%. Strain YS-37T also showed some biophysical and biochemical differences with the related strains, especially in hydrolysis of casein. The results demonstrated that strain YS-37T belongs to genus Lysobacter and represents a novel Lysobacter species for which the name Lysobacter tongrenensis sp. nov. is proposed. The type strain is YS-37T (= CCTCC AB 2016052T = KCTC 52206T). PMID- 29188344 TI - Citreibacter salsisoli gen. nov., sp. nov., a bacterium isolated from marine soil. AB - A Gram-stain-negative, strictly aerobic, yellow-colored, rod-shaped, chemoheterotrophic bacterium, designated SNA426T, was isolated from marine soil in the Republic of Korea. Preliminary analysis based on the 16S rRNA gene sequence revealed that the novel marine isolate was affiliated with the family Flavobacteriaceae of phylum Bacteroidetes and that it shared the highest (96.2%) sequence similarity with Gillisia mitskevichiae KMM 6034T. The strain could be differentiated phenotypically from related members of the family Flavobacteriaceae. The major fatty acids of strain SNA426T were iso-C15:0, C16:1 omega7c and/or C16:1 omega6c and iso-C17:0 3-OH. The DNA G+C content of the strain was 39.6 mol% and the major respiratory quinone was menaquinone 6 (MK-6). Strain SNA426T had phosphatidylethanolamine, phosphatidylcholine, three unidentified aminolipids and nine unidentified lipids as polar lipids. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus in the family Flavobacteriaceae, for which the name Citreibacter gen. nov. is proposed. The type species is Citreibacter salsisoli sp. nov., with the type strain SNA426T (= KCCM 90269T = CGMCC 1.16129T). PMID- 29188346 TI - [Diagnosis, treatment and follow-up of testicular cancer]. AB - BACKGROUND: Testicular cancer is a disease of young adult men, and it is curable in most cases. Even in advanced disease, cure rates reach 80 % nowadays. This was achieved by consistently performing studies concerning the different stages of disease. TREATMENT AND FOLLOW-UP CARE: The concept of treatment is interdisciplinary. After removal of the affected testis, histology and stage determine further therapy, which can be active surveillance, polychemotherapy, radiotherapy, surgery, or a combination of these. Curability also has consequences for the long-term follow-up. We speak about long-term survivorship. Besides looking for recurrences, it is also necessary to observe and treat long term toxicities caused by the different therapeutic procedures. CONCLUSION: Because testicular cancer is rare with about 4500 cases annually, treatment especially for advanced disease-should be performed at centers. In addition, it is possible to obtain a second opinion using the Interdisciplinary German Testicular Study Group website. PMID- 29188347 TI - [From boxing to geriatric psychiatry : Facets from the work of East German social psychiatrist Bernhard Schwarz (1918-1991)]. AB - For the first time, this study presents publications representative for the work of the neurologist and sports physician Bernhard Schwarz, whose career spans from the 1950s to the 1970s. His work is characterized by exceptional originality. Schwarz acted as the physician of the GDR national boxing team and conducted a systematic long-term study of 800 boxers. He found increased occurrences of depression, Alzheimer's and Parkinson's diseases and suggested that these were linked to recurring craniocerebral injury. He was concerned about avoiding such long-term health effects in boxers and suggested a range of preventive measures that were later reflected in the guidelines of international boxing associations. Schwarz was distinguished by his drive to directly implement social psychiatric approaches in the hospital. As head of the psychiatric clinic at Leipzig University, he initiated a club for geriatric patients to help older patients with the problematic transition from hospitalization to outpatient assistance at home. Influenced by holistic anthropological thinking, he regarded geriatric mental illness as a consequence of social isolation. In addition, Schwarz was involved in a model project that assessed the work resilience of patients in the hospital with the goal of optimizing psychiatric rehabilitation. Both projects were successes, according to his published accounts. PMID- 29188345 TI - Imaging in syndesmotic injury: a systematic literature review. AB - OBJECTIVES: To give a systematic overview of current diagnostic imaging options for assessment of the distal tibio-fibular syndesmosis. MATERIALS AND METHODS: A systematic literature search across the following sources was performed: PubMed, ScienceDirect, Google Scholar, and SpringerLink. Forty-two articles were included and subdivided into three groups: group one consists of studies using conventional radiographs (22 articles), group two includes studies using computed tomography (CT) scans (15 articles), and group three comprises studies using magnet resonance imaging (MRI, 9 articles).The following data were extracted: imaging modality, measurement method, number of participants and ankles included, average age of participants, sensitivity, specificity, and accuracy of the measurement technique. The Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool was used to assess the methodological quality. RESULTS: The three most common techniques used for assessment of the syndesmosis in conventional radiographs are the tibio-fibular clear space (TFCS), the tibio-fibular overlap (TFO), and the medial clear space (MCS). Regarding CT scans, the tibio-fibular width (axial images) was most commonly used. Most of the MRI studies used direct assessment of syndesmotic integrity. Overall, the included studies show low probability of bias and are applicable in daily practice. CONCLUSIONS: Conventional radiographs cannot predict syndesmotic injuries reliably. CT scans outperform plain radiographs in detecting syndesmotic mal-reduction. Additionally, the syndesmotic interval can be assessed in greater detail by CT. MRI measurements achieve a sensitivity and specificity of nearly 100%; however, correlating MRI findings with patients' complaints is difficult, and utility with subtle syndesmotic instability needs further investigation. Overall, the methodological quality of these studies was satisfactory. PMID- 29188348 TI - [Big data approaches in psychiatry: examples in depression research]. AB - BACKGROUND: The exploration and therapy of depression is aggravated by heterogeneous etiological mechanisms and various comorbidities. With the growing trend towards big data in psychiatry, research and therapy can increasingly target the individual patient. This novel objective requires special methods of analysis. OBJECTIVE: The possibilities and challenges of the application of big data approaches in depression are examined in closer detail. MATERIAL AND METHODS: Examples are given to illustrate the possibilities of big data approaches in depression research. Modern machine learning methods are compared to traditional statistical methods in terms of their potential in applications to depression. RESULTS: Big data approaches are particularly suited to the analysis of detailed observational data, the prediction of single data points or several clinical variables and the identification of endophenotypes. A current challenge lies in the transfer of results into the clinical treatment of patients with depression. CONCLUSION: Big data approaches enable biological subtypes in depression to be identified and predictions in individual patients to be made. They have enormous potential for prevention, early diagnosis, treatment choice and prognosis of depression as well as for treatment development. PMID- 29188349 TI - ["Understanding" in psychiatry -Part 2 : From incomprehensibility to an attitude of participative communication]. AB - BACKGROUND: Starting from a systematic research of "incomprehensibility" we propose a turn from an epistemological analysis of "to understand" to an anthropological perspective relying on participative communication in a shared space of resonance. METHOD: We propose a systematization of the modes of understanding and of incomprehensibility based on a two-dimensional model combining epistemological and ontological perspectives. Finally, we outline "understanding" as a medical stance related to the healing relationship, which implies a disposition to get involved in a participative communication. We put forward the hypothesis that acceptance of the otherness of the patient, without the intention of a complete appropriation of meaning, could be noted as crucial feature of the anthropological approach. RESULTS: In clinical medicine, especially in psychiatry, "not understood" is threefold: as "misunderstanding", as "not-understanding" (as a temporary lack of understanding), and as incomprehensibility (to understand, that there is nothing to be understood). Incomprehensibility may only allow for interpretative operations up to a certain limit. This unidirectional understanding as a diagnosing subsumption or as a psychological explanation in order to grasp meanings has to be completed by a bi directional personal approach based on an engaging attitude (dialogical as well as quiescent) while acknowledging the incomprehensible. DISCUSSION: A second person-perspective emphasizes the healing relationship as an existential encounter, especially in personal liminal situations for the patient. From an anthropological perspective "to understand" has not only to be grasped as a semantic agreement, but also as an attitude towards participative communication. That means a disposition to get involved in the encounter with the mentally ill without aiming for grasping rationally significances or even to attribute meanings. The stance therefore should be based on an awareness for the patient's idiosyncrasy as well as on the empathetic production of a shared space of resonance within the healing relationship. PMID- 29188350 TI - ["Understanding" in psychiatry-part 1 : Philosophical sources and concept analysis]. AB - BACKGROUND: The dichotomy comprehension/understanding vs. explanation has been initially developed with a legitimating intention for the humanities vis a vis the natural sciences. This investigation examines the different usages of understanding/comprehension in psychiatry and psychotherapy as well as its relevance for medical practice. METHOD: Critical discussion of the historical roots of the comprehension-explanation dichotomy and its introduction into the psychiatry by Jaspers. A propaedeutic logical analysis of the concept of "understanding" will be proposed. This investigation aims to elucidate latent dimensions in the usage of "understanding" in psychiatry and psychotherapy. In more detail the operation of assignment and attribution will be discussed as well as the elucidation of individual meaning and supraindividual significance. RESULTS: The term analysis shows that "to understand" as a predicate is gradually and polysemic; its definition must take the different logically additive meanings into account. These meanings can be condensed into three dimensions: i. Rational diagnostic assignment; ii. Elucidation of meaning through individual empathetic re-experiencing as a psychological approach respectively the supraindividual elucidation of significance, and; iii. Dialogic attitude. Psychological understanding roots in Jaspers' epistemology on assignment to and alignment with supraindividual meaningful connections and not on empathetic re-experiencing. DISCUSSION: "To understand" as a logical operation of assignment and as meaning elucidation takes for granted a predicate in its transitive first-person perspective ("who" should be understood, as objectified) in conjunction to a third-person perspective ("what" should be understood). This analysis should be complemented by a first-person perspective ("who" should be understood, as a subject) in conjunction with a dialogic second-person perspective ("how" should be understood, following a mutual disposition). This last approach will be discussed in an additional article. PMID- 29188351 TI - [Chronic course of neurosyphilis]. PMID- 29188352 TI - [Prospective DRG coding : Improvement in cost-effectiveness and documentation quality of in-patient hospital care]. AB - BACKGROUND: In prospective reimbursement schemes a diagnosis-related group (DRG) is assigned to each case according to all coded diagnoses and procedures. This process can be conducted retrospectively after (DC) or prospectively during the hospitalization (PC). The use of PC offers advantages in terms of cost effectiveness and documentation quality without impairing patient safety. MATERIAL AND METHODS: A retrospective analysis including all DRG records and billing data from 2012 to 2015 of a surgical department was carried out. The use of PC was introduced into the vascular surgery unit (VS) in September 2013, while the remaining surgical units (RS) stayed with DC. Analysis focused on differences between VS and RS before and after introduction of PC. Characteristics of cost effectiveness were earnings (EBIT-DA), length of stay (LOS), the case mix index (CMI) and the productivity in relation to the DRG benchmark (productivity index, PI). The number of recorded diagnoses/procedures (ND/NP) was an indicator for documentation quality. RESULTS: A total of 1703 cases with VS and 27,679 cases with RS were analyzed. After introduction of PC the EBIT-DA per case increased in VS but not in RS (+3342 Swiss francs vs. +84, respectively, p < 0.001). The CMI increased slightly in both groups (+0.10 VS vs. +0.08 RS, p > 0.05) and the LOS was more reduced in VS than in RS (-0.36 days vs. -0.03 days, p > 0.005). The PI increased in VS but decreased in RS (+0.131 vs. -0.032, p < 0.001), ND increased more in VS (+1.29 VS vs. +0.26 RS, p < 0.001) and NP remained stable in both groups. CONCLUSION: The use of PC helps to significantly improve cost effectiveness and documentation quality of in-patient hospital care, essentially by optimizing LOS and cost weight in relation to the DRG benchmark, i. e. increasing the PI. The increasing ND indicates an improvement in documentation quality. PMID- 29188353 TI - [Quality indicators for surgery of rectal cancer : Evidence-based development of a set of indicators for quality]. AB - The definition of valid quality indicators is an essential task of medical self administration and quality assurance. Based on the literature and the results of the Study, Documentation, and Quality Center (StuDoQ) Rectal Cancer Registry, we suggest the following QIs: rate of circumferential resection margin (CRM) positive resected material, rate of anastomotic leak in patients with anastomoses, rate of abdominal wound healing disorders and rate of patients with newly established permanent urinary diversion. Additionally, a new marker, the MTL30, which subsumes patient death within 30 days after the index operation, patient transfer to another acute hospital within 30 days after the index operation or a length of inpatient hospital stay of more than 30 days. PMID- 29188354 TI - [Endoscopic techniques for early stage cancer of the upper and lower gastrointestinal tract : Possibilities and limitations]. AB - BACKGROUND: Endoscopic resection (ER) provides a minimally invasive treatment option for early gastrointestinal cancers. OBJECTIVE: Presentation of current guideline recommendations. Presentation and discussion of published data regarding ER of early esophageal cancer, early gastric cancer and early colorectal cancer. MATERIAL AND METHODS: Analysis of the current literature. Presentation of endoscopic case reports. RESULTS: New technologies, e. g. narrow band imaging (NBI) have improved the endoscopic diagnosis of early gastrointestinal neoplasms. The development of endoscopic submucosal dissection (ESD) allowed higher R0 resection rates and minimized the recurrence risk leading to higher rates of curative endoscopic resection. Resection criteria are defined in national and international guidelines. Resection criteria for early gastric cancer are different between German (guideline criteria) and Asian guidelines (expanded criteria). New German data did not show a difference in long-term survival after ESD of early gastric cancers fulfilling the guideline criteria or the expanded criteria. In early colorectal cancer submucosal invasion exceeding 1000 um is defined as the limit for ER in current guidelines. This threshold might be too strict for subgroups without further risk factors but further data are awaited. CONCLUSION: Substantial progress has been made in endoscopic diagnostics and treatment of early gastrointestinal cancers. First European data could confirm previous Asian results; however, further studies are urgently needed for a better definition of the possibilities and limitations of ER. PMID- 29188355 TI - [Resection concepts for early stage neuroendocrine tumors of the lungs and bronchi]. AB - BACKGROUND: Neuroendocrine tumors of the lungs are a very inhomogeneous group of malignancies. The surgical treatment should be adapted to the anatomical localization and histological subtype and individualized according to the functional reserve. MATERIAL AND METHODS: We performed a selective review of current literature, which was supplemented by personal experiences. RESULTS: The currently available outcome data are very inhomogeneous and depend on the histological subtype of neuroendocrine pulmonary tumors. A radical R0 resection is the key for an improvement in long-term overall and disease-free survival. CONCLUSION: Surgical treatment of carcinoid tumors is the current standard therapy. Sleeve resection should be performed, whenever possible. More aggressive tumors, such as large cell neuroendocrine carcinoma and small cell lung cancer should be treated in a multimodal concept. PMID- 29188356 TI - [Antihypertensive therapy in the elderly]. AB - Arterial hypertension is the most common modifiable risk factor for cerebrovascular and cardiovascular morbidity and mortality in old age. The prevention of cognitive brain disorders is also a therapeutic goal of long-term treatment of hypertension. Older patients also have a higher risk of developing cardiovascular diseases and therefore benefit from a relatively moderate reduction in blood pressure. With respect to the high prevalence of hypertension in old age and the increasing incidence with time, the therapy of hypertension is becoming increasingly more important to achieve an improved prognosis for patients along with a reduction of costs. The accurate blood pressure measurement for elderly patients includes repeated measurements while standing and sitting. Additionally, the measurements should also be conducted by the patient or by a family member. The most accurate method for assessing the daily blood pressure level, e.g. practice hypertension, non-dipping and intermittent hypertension, is the 24-h blood pressure measurement by ambulatory blood pressure monitoring (ABPM). General measures and lifestyle interventions are effective for reducing blood pressure of elderly patients with hypertension and a low salt diet is scientifically proven to be superior. The same drugs used for young people are also recommended for older patients and most give preference to diuretics, renin angiotensin-aldosterone system (RAAS) inhibitors and calcium antagonists. The target blood pressure in elderly patients is repeatedly the focus of scientific discussions. The current recommendations are presented in the text and the characteristics which must be particularly considered in the therapy of elderly patients are presented in detail. PMID- 29188357 TI - [Management of valvular heart disease : ESC/EACTS guidelines 2017]. AB - After 5 years the European Society of Cardiology and the European Association for Cardio-Thoracic Surgery have released an update on the guidelines for the management of valvular heart diseases. In recent years published results of randomized trials in patients with aortic valve stenosis have resulted in updated recommendations for catheter-based prosthesis implantation (TAVI), which is now extended to patients presenting without a low risk for conventional surgical valve replacement. In mitral or tricuspid valvular disease, the recommendations for catheter-based therapies are less strong because of a lack of supportive scientific data. A special focus of these updated guidelines is on concomitant antithrombotic therapy in valvular heart disease and in the context of a combination with coronary artery disease and/or accompanying arrhythmia. Special emphasis was again put on the multidisciplinary heart team for the diagnostics and treatment of patients with valvular heart disease. In order to support the quality of treatment for patients with valvular heart disease, it is suggested that heart valve centers of excellence should be established, which have to fulfil complex personnel, structural and technological prerequisites. PMID- 29188358 TI - Anticoagulation strategies in patients with atrial fibrillation after PCI or with ACS : The end of triple therapy? AB - Clinicians struggle daily with the optimal regimen for patients with an indication for antiplatelet therapy after stenting and in patients needing oral anticoagulation treatment for atrial fibrillation (AF). This is not only difficult in patients with acute coronary syndrome (ACS) but also in the large number of patients with AF undergoing elective percutaneous coronary intervention (PCI). The challenge is to strike a balance between the increasing risk of bleeding events and ischemic or thrombotic events. Until recently, guidelines were based on expert consensus and a few small, many of them retrospective, trials. A so-called triple therapy with a vitamin K antagonist (VKA) and dual antiplatelet therapy (DAPT) with aspirin and clopidogrel was recommended for patients with AF undergoing PCI in stable coronary artery disease or for those with ACS. However, severe bleeding complications remain a major issue during triple therapy, particularly in the growing aging population. In the past year, randomized controlled trials (RCT) with direct-acting oral anticoagulants (DOACs) have modified the standard use of care, now favoring dual therapy with DOACs. This review elucidates the current influential RCTs on the new antiplatelet and anticoagulation strategies for patients with AF undergoing PCI or with ACS, and discusses whether triple therapy is still required. PMID- 29188359 TI - Biosynthesis of gold nanoparticles using cell-free extracts of Magnusiomyces ingens LH-F1 for nitrophenols reduction. AB - A green and eco-friendly method for the synthesis of gold nanoparticles (AuNPs) was developed using the cell-free extracts of a yeast strain Magnusiomyces ingens LH-F1. UV-vis spectra showed a distinct absorption band at ~ 540 nm, corresponding to the surface plasmon resonance of AuNPs. Transmission electron microscopy images revealed that the shapes of AuNPs were almost spherical and pseudo-spherical. Fourier transform infrared spectroscopy and sodium dodecyl sulfate-polyacrylamide gel electrophoresis analyses suggested that some proteins containing amino- and carboxyl-groups in the cell-free extracts were absorbed on the surface of nanoparticles, which could act as reducing and capping agents for AuNPs synthesis. Furthermore, with the concentration of cell-free extracts increasing from 25 to 200 mg L-1, the average size of AuNPs decreased from 28.3 to 20.3 nm. Meanwhile, the morphology became more uniform with less irregular shapes. In addition, the as-synthesized AuNPs showed an excellent catalytic activity for nitrophenols reduction (i.e., 4-nitrophenol, 3-nitrophenol and 2 nitrophenol) in the presence of excess NaBH4. The catalytic rate constant of nitrophenols reduction was also dependent on cell-free extract concentration. The larger AuNPs synthesized by less cell-free extracts were covered with a thinner corona and showed better capacity for reducing nitrophenols. This study suggested that the as-synthesized AuNPs could be employed as efficient catalysts in reduction of organic contaminants. PMID- 29188360 TI - HANP on renal damage during cardiac surgery. PMID- 29188361 TI - Disruptive technological advances in vascular access for dialysis: an overview. AB - End-stage kidney disease (ESKD), one of the most prevalent diseases in the world and with increasing incidence, is associated with significant morbidity and mortality. Current available modes of renal replacement therapy (RRT) include dialysis and renal transplantation. Though renal transplantation is the preferred and ideal mode of RRT, this modality may not be available to all patients with ESKD. Moreover, renal transplant recipients are constantly at risk of complications associated with immunosuppression and immunosuppressant use, and posttransplant lymphoproliferative disorder. Dialysis may be the only available modality in certain patients. However, dialysis has its limitations, which include issues associated with lack of vascular access, risks of infections and vascular thrombosis, decreased quality of life, and absence of biosynthetic functions of the kidney. In particular, the creation and maintenance of hemodialysis vascular access in children poses a unique set of challenges to the pediatric nephrologist owing to the smaller vessel diameters and vascular hyperreactivity compared with adult patients. Vascular access issues continue to be one of the major limiting factors prohibiting the delivery of adequate dialysis in ESKD patients and is the Achilles' heel of hemodialysis. This review aims to provide a critical overview of disruptive technological advances and innovations for vascular access. Novel strategies in preventing neointimal hyperplasia, novel bioengineered products, grafts and devices for vascular access will be discussed. The potential impact of these solutions on improving the morbidity encountered by dialysis patients will also be examined. PMID- 29188363 TI - Meta-analysis of adjunctive dexamethasone to improve clinical outcome of bacterial meningitis in children. AB - BACKGROUND: The current recommended therapies for bacterial meningitis are effective antimicrobial agents and the implementation of childhood vaccination programs. However, the role of adjunctive dexamethasone therapy in bacterial meningitis remains controversial. METHODS: Using meta-analysis, this study aims to investigate the efficacy of adjunctive dexamethasone therapy in bacterial meningitis by comparing it with antibiotic therapy. Documents of randomized controlled trials (RCT) related to the treatment of bacterial meningitis in children with dexamethasone published since the establishment of the databases to December in 2016 were retrieved from the databases of Cochrane Library, Pubmed, MEDLINE, EMBASE, Chinese BioMedical Literature Database, and China National Knowledge Infrastructure. The references in RCT were retrieved by hands at the same time. Full texts of screened documents were searched and given qualitative review, and then, all RCT included were analyzed statistically by using Review Manger 5.3 software. RESULTS: The search yielded 15 studies (2409 children cases), among which 4 fall in grade A and 11 were grade B. The results of meta analysis have shown that patients who received dexamethasone have significantly lower risks in incidence of hearing loss (OR = 0.68, 95%CI 0.53-0.89, P = 0.004) and severe neurological sequelae (OR = 0.59, 95%CI 0.37-0.95, P = 0.03), but the follow-up mortality is hardly effected (OR = 0.86, 95%CI 0.67-1.10, P = 0.23). CONCLUSIONS: Evidence has proven that the adjunctive administration of dexamethasone is conducive to treating children with bacterial meningitis to a certain extent, to decreasing the possibility of hearing loss and severe neurological sequelae, but has no significant effect on the follow-up mortality. PMID- 29188362 TI - The NF-kappaB signalling pathway in colorectal cancer: associations between dysregulated gene and miRNA expression. AB - BACKGROUND: The nuclear factor-kappa B (NF-kappaB) signalling pathway is a regulator of immune response and inflammation that has been implicated in the carcinogenic process. We examined differentially expressed genes in this pathway and miRNAs to determine associations with colorectal cancer (CRC). METHODS: We used data from 217 CRC cases to evaluate differences in NF-kappaB signalling pathway gene expression between paired carcinoma and normal mucosa and identify miRNAs that are associated with these genes. Gene expression data from RNA-Seq and miRNA expression data from Agilent Human miRNA Microarray V19.0 were analysed. We evaluated genes most strongly associated and differentially expressed (fold change (FC) of > 1.5 or < 0.67) that were statistically significant after adjustment for multiple comparisons. RESULTS: Of the 92 genes evaluated, 22 were significantly downregulated and nine genes were significantly upregulated in all tumours. Two additional genes (CD14 and CSNK2A1) were dysregulated in MSS tumours and two genes (CARD11 and VCAM1) were downregulated and six genes were upregulated (LYN, TICAM2, ICAM1, IL1B, CCL4 and PTGS2) in MSI tumours. Sixteen of the 21 dysregulated genes were associated with 40 miRNAs. There were 76 miRNA:mRNA associations of which 38 had seed-region matches. Genes were associated with multiple miRNAs, with TNFSRF11A (RANK) being associated with 15 miRNAs. Likewise several miRNAs were associated with multiple genes (miR-150 5p with eight genes, miR-195-5p with four genes, miR-203a with five genes, miR 20b-5p with four genes, miR-650 with six genes and miR-92a-3p with five genes). CONCLUSIONS: Focusing on the genes and their associated miRNAs within the entire signalling pathway provides a comprehensive understanding of this complex pathway as it relates to CRC and offers insight into potential therapeutic agents. PMID- 29188364 TI - Complete genome sequence of Paris mosaic necrosis virus, a distinct member of the genus Potyvirus. AB - The complete genomic sequence of a novel potyvirus was determined from Paris polyphylla var. yunnanensis. Its genomic RNA consists of 9,660 nucleotides (nt) excluding the 3'-terminal poly (A) tail, containing the typical open reading frame (ORF) of potyviruses and encoding a putative large polyprotein of 3030 amino acids. The virus shares 53.9-70.1% nt sequence identity and 43.9-73.2% amino acid sequence identity with other viruses classified within the genus Potyvirus. Proteolytic cleavage sites and conserved motifs of the potyviruses were identified in the polyprotein and within individual proteins. Phylogenetic analysis indicated that the virus is most closely related to members of the BCMV subgroup. The results suggest that the virus should be classified as a novel species within the genus Potyvirus, which we tentatively name "Paris mosaic necrosis virus". PMID- 29188365 TI - A reaction-diffusion malaria model with seasonality and incubation period. AB - In this paper, we propose a time-periodic reaction-diffusion model which incorporates seasonality, spatial heterogeneity and the extrinsic incubation period (EIP) of the parasite. The basic reproduction number [Formula: see text] is derived, and it is shown that the disease-free periodic solution is globally attractive if [Formula: see text], while there is an endemic periodic solution and the disease is uniformly persistent if [Formula: see text]. Numerical simulations indicate that prolonging the EIP may be helpful in the disease control, while spatial heterogeneity of the disease transmission coefficient may increase the disease burden. PMID- 29188366 TI - Pre-operative neutrophil count and neutrophil-lymphocyte count ratio (NLCR) in predicting the histological grade of paediatric brain tumours: a preliminary study. AB - INTRODUCTION: The neutrophil-lymphocyte count ratio (NLCR) is an established prognostic marker for renal, lung and colorectal carcinomas and has been suggested to be predictive of histological grade and outcome in adult intracranial tumours. The purpose of this study was to determine whether a correlation of the pre-operative neutrophil count (NC) and NLCR with the final histological grade exists in paediatric intracranial tumours. METHODS: A retrospective analysis was undertaken at a single centre. Patients less than 18 years old at the time of surgery who underwent tumour-related procedures from 2006 to 2015 were included. Patients with recurrent tumours, previous bone marrow transplant and metastases were excluded. Pre-operative full blood counts (FBC), collected before the diagnosis of intracranial pathology and before administration of steroids, were matched with histological diagnosis for each patient. Post-operative FBC was also recorded, together with survival data where applicable. RESULTS: A total of 116 patients (74 male, 42 female; mean age, 8 +/- 0.9 years) with a diagnosis of primary intracranial tumours had pre-operative FBC that could be matched to final histological grade. Pre-operative NC and NLCR were higher with increasing grade of tumour: grade 1 (NC 4.29 109/l, NLCR 2.26), grade 2 (NC 4.59 109/l, NLCR 2.38), grade 3 (NC 5.67 109/l, NLCR 2.72) and grade 4 (NC 6.59 109/l, NLCR 3.31). Patients with WHO grade 1 and 2 tumours pooled together had a lower NC (4.37 95% CI +/- 0.67 109/l) compared to WHO grade 3 and 4 patients (6.41 95% CI +/- 0.99 109/l, p = 0.0013). The NLCR was lower in grade 1 and 2 tumours (2.29 +/- 0.59) (compared to grade 3 and 4 tumours; 3.20 +/- 0.76) but this did not reach significance (p = 0.069). The subgroup of patients with pilocytic astrocytoma had a significantly lower NC when compared to patients with high-grade tumours (p = 0.005). Medulloblastoma and supratentorial PNET subgroups had significantly higher NC compared to the low-grade group (p = 0.033, p = 0.002). Post-operative NC was significantly higher in the high-grade tumours (p = 0.034), but no difference was observed for NLCR (p = 0.28). CONCLUSIONS: No evidence exists to support the correlation of pre-operative NC or NLCR to histological diagnosis in paediatric intracranial tumours. Our results indicate that a higher pre-operative NC/NLCR correlates with a higher histological grade of tumour. This suggests that immunological mechanisms may be involved in the pathogenesis of paediatric brain tumours, and a further prospective study is required to substantiate and expand these findings.

Herein, we report a case of traumatic vertebral artery rupture causing extensive intraspinal hematoma and progressive neurological symptoms. PMID- 29188368 TI - In vitro and in vivo thermal stress induces proliferation of Blastocystis sp. AB - Blastocystis sp. is known to be the most commonly found intestinal protozoan parasite in human fecal surveys and has been incriminated to cause diarrhea and abdominal bloating. Binary fission has been widely accepted as the plausible mode of reproduction for this parasite. The present study demonstrates that subjecting the parasites in vitro to higher temperature shows the proliferation of parasite numbers in cultures. Transmission electron microscopy was used to compare the morphology of Blastocystis sp. subtype 3 isolated from a dengue patient having high fever (in vivo thermal stress) and Blastocystis sp. 3 maintained at 41 degrees C (in vitro thermal stress) and 37 degrees C (control). Fluorescence stains like acridine orange (AO) and 4',6'-diamino-2-phenylindole (DAPI) were used to demonstrate the viability and nuclear content of the parasite for both the in vitro and in vivo thermal stress groups of parasites. Blastocystis sp. at 37 degrees C was found to be mostly vacuolar whereas the in vitro thermal stressed isolates at 41 degrees C were granular with electron dense material seen to protect the granules within the central body. Parasites of the in vivo thermal stressed group showed similar ultrastructure as the in vitro ones. AO and DAPI staining provided evidence that these granules are viable which develop into progenies of Blastocystis sp. These granular forms were then observed to rupture and release progenies from the mother cells whilst the peripheral cytoplasmic walls were seen to degrade. Upon exposure to high temperature both in vitro and in vivo, Blastocystis sp. in cultures show higher number of granular forms seen to be protected by the electron dense material within the central body possibly acting as a protective mechanism. This is possibly to ensure the ability to survive for the granules to be developed as viable progenies for release into the host system. PMID- 29188370 TI - Predictors of cerclage failure in patients with singleton pregnancy undergoing prophylactic cervical cerclage. AB - PURPOSE: The role of cervical cerclage to prevent preterm birth (PTB) remains controversial. The aim of this study was to identify prognostic factors for cerclage failure among singleton pregnant women following prophylactic cerclage (PC). METHODS: A retrospective analysis of PC was performed in a single center. The main outcome measure was cerclage failure, defined by spontaneous early PTB prior to 32 weeks' gestation. Age, BMI, history of instrumentation of the uterus, history of second trimester miscarriage, previous conization, positive vaginal swab prior cerclage, gestational age at time of cerclage, CRP 1 week after cerclage and post-cerclage US changes of cervical length were tested as predictive factors. Descriptive statistical and binary logistic regression analyses were performed. RESULTS: 141 women underwent cerclage procedures between 2007 and 2016. 39 patients had PC with McDonald suture, singleton pregnancy and complete clinical follow-up information, thus fulfilling the inclusion criteria. Multivariate analysis showed that history of instrumentation of the uterus was the only independent prognostic factor [OR = 0.14 (0.03, 0.72) p = 0.019] for cerclage failure. CONCLUSION: This is the first study showing that a history of previous uterine instrumentation is an independent predictor of cerclage failure. This finding has significant clinical implications for women of childbearing age, particularly when management of miscarriage/abortion is being considered. Women should be informed about the potential risks when counseled prior to surgical evacuation and medical management or cervical ripening should be considered. These results are also helpful in counseling patients undergoing cerclage, when a prior uterine instrumentation has been performed. PMID- 29188371 TI - Urinary iodine concentration and thyroid hormones: Korea National Health and Nutrition Examination Survey 2013-2015. AB - PURPOSE: An epidemiologic study that evaluated population's iodine nutrition status and its relationship with thyroid hormones is lacking in iodine-sufficient area. This nationwide study aimed to evaluate the iodine nutrition status in Korea and relationship between urine iodine concentration (UIC) and thyroid hormones. METHODS: A total of 8318 subjects of the Korea National Health and Nutrition Examination Survey VI (2013-2015) with UIC and thyroid hormone evaluation were included. Median UIC level and estimated 24-h iodine intake were calculated. The prevalence of iodine deficiency or excess was obtained using estimated average requirement or above the tolerable upper intake level cut-point method by estimated iodine intake. We analyzed UIC with regard to age, sex, social economic status, and geographic characteristics. RESULTS: The median UIC in general population and estimated iodine intake in adult population were 293.9 MUg/L (above requirement according to World Health Organization classification) and 249.3MUg/day, respectively. The prevalence of iodine deficiency and excess was 14.0 and 13.4%. The median UIC was higher among SAC [511 (299.9-948.5)] and lower among seventies [251.2 (98.9-761.6)] compared to other age groups. The median UIC increased with household income level (p for trend < 0.001). The subjects living in rural and inland region had lowest UIC among the enrolled subjects. The subgroups with higher median UIC were associated with higher mean TSH levels. CONCLUSIONS: This first nationwide study in Korea demonstrated that the median of UIC and estimated iodine intake lie at nearly 300 ug/L and 250 ug/day, respectively, which shows an overall excellent iodine nutrition. PMID- 29188369 TI - Immune modulation of Th1, Th2, and T-reg transcriptional factors differing from cytokine levels in Schistosoma japonicum infection. AB - In spite of long-term integrated control programs for Schistosoma japonicum infection in China, the infection is still persistent due to its zoonotic transmission and disease severity which further complicate its control. Th1, Th2, and T-reg cells are involved in S. japonicum immunity; however, their exact roles in immunopathology of this infection are still questionable. Therefore, the monitoring of these T cell subsets' immune responses during a primary infection of S. japonicum at both transcriptional (mRNA) and protein (cytokines) levels would be essential to point out. In experimentally infected white New Zealand rabbits, mRNA expression levels of TBX2, IRF8, GATA3, STAT6, FoxP3, and MAFF were evaluated using qPCR, whereas Th1 (IFN-gamma and TNF-alpha), Th2 (IL4 and IL13), and T-reg (IL10 and TGF-beta1) cytokines were measured by ELISA test. Those parameters were estimated at two phases: the first being 4 and 8 weeks post infection and the second phase at 12 weeks post-infection. The infected rabbits were categorized into group1 which was treated with praziquantel after the 8th week of infection and group 2 which was left untreated. In the first stage of infection, Th1 was superior to the other types at both mRNA (TBX2 and IRF8) and protein (IFN-gamma and TNF-alpha) levels, but at the late stage, Th2 cytokines (IL4 and IL13) were surprisingly dominated without comparable change in Th2 transcriptional level in group 1. Concisely, the evaluation of T cell transcriptional factors provided clearer evidence about T cellular roles which would be a valuable supplement to control this disease in terms of protective and therapeutic vaccinations. PMID- 29188372 TI - Efficacy of ultrasound-guided core needle biopsy in cervical lymphadenopathy: A retrospective study of 6,695 cases. AB - OBJECTIVES: To determine the diagnostic yield of ultrasound-guided core needle biopsy (US-CNB) in cervical lymphadenopathy and identify the factors influencing the diagnostic accuracy of US-CNB. METHODS: We retrospectively reviewed the records of 6,603 patients with cervical lymphadenopathy who underwent 6695 US-CNB procedures between 2004 and 2017. RESULTS: Adequate specimens were obtained in 92.19 % (6,172/6,695) of cases. Most lymph nodes (67.65 %) were malignant (metastatic carcinoma 4,131; lymphoma 398). The overall accuracy of US-CNB for differentiating benign from malignant lesions was 91.70 % (6,139/6,695). Among biopsies in which adequate material was obtained, the sensitivity, specificity and accuracy of US-CNB were 99.70 %, 100 % and 99.46 %, respectively. The success or failure of US-CNB for the diagnosis of lymphadenopathy was significantly correlated with node size, nature (malignant vs. benign), and location as well as penetration depth, but not with needle size (p = 0.665), number of core tissues obtained (p = 0.324), or history of malignancy (p = 0.060). There were no major procedure-related complications. CONCLUSIONS: US-CNB is a safe and effective method of diagnosing cervical lymphadenopathy, and our findings may help optimise the sampling procedure by maximising its diagnostic accuracy and preserving its minimally invasive nature. KEY POINTS: * US-CNB is useful for the diagnosis of cervical lymphadenopathy. * US-CNB is safe to perform on lymph nodes located near vital structures. * Larger, malignant, level IV lymph nodes yield sufficient tissue samples more easily. PMID- 29188373 TI - L5 pedicle subtraction osteotomy: indication, surgical technique and specificities. AB - PURPOSE: To evaluate the radiographic, functional outcomes, complications and surgical specificities of L5 pedicle subtraction osteotomy for fixed sagittal and coronal malalignment. METHODS: A retrospective cohort of consecutive patients with prospectively collected data. Ten patients who underwent PSO at L5 were eligible for a 2-year minimum follow-up (average, 4.0 years). Patients were evaluated by standardized upright radiographs. Preoperative and postoperative radiographies, surgical data and complications were collected. RESULTS: All surgeries were revision surgeries. The mean lumbar lordosis before surgery was - 22.5 degrees (range, 8 degrees to - 33 degrees ) and improved to - 58.5 degrees (range, - 40 degrees to - 79 degrees ). The sagittal vertical axis demonstrated a preoperative mean sagittal malalignment of 13.7 cm (range 3.5 to 20 cm), with correction to 4.6 cm postoperatively. Three patients required additional surgery at the latest follow-up for rod breakage. CONCLUSIONS: PSO of L5 can be a safe and effective technique to treat and correct fixed sagittal imbalance and provide biomechanical stability. The high complication rate mandates a careful assessment of the risk/benefit ratio of such a major surgery. Most patients are satisfied, particularly when sagittal balance is achieved. PMID- 29188374 TI - Characterization of a gene regulatory network underlying astringency loss in persimmon fruit. AB - MAIN CONCLUSION: Transcriptome analysis of a persimmon population segregating for an astringency trait in fruit suggested central roles for a limited number of transcriptional regulators in the loss of proanthocyanidin accumulation. Persimmon (Diospyros kaki; 2n = 6x = 90) accumulates a large amount of proanthocyanidins (PAs) in its fruit, resulting in an astringent taste. Persimmon cultivars are classified into four types based on the nature of astringency loss and the amount of PAs at maturity. Pollination constant and non-astringent (PCNA) type cultivars stop accumulating PAs in the early stages of fruit development and their fruit can be consumed when still firm without the need for artificial deastringency treatments. While the PCNA trait has been shown to be conferred by a recessive allele at a single locus (ASTRINGENCY; AST), the exact genetic determinant remains unidentified. Here, we conducted transcriptome analyses to elucidate the regulatory mechanism underlying this trait using developing fruits of an F1 population segregating for the PCNA trait. Comparisons of the transcriptomes of PCNA and non-PCNA individuals and hierarchical clustering revealed that genes related to the flavonoid pathway and to abiotic stress responses involving light stimulation were expressed coordinately with PA accumulation. Furthermore, coexpression network analyses suggested that three putative transcription factors were central to the PA regulatory network and that at least DkMYB4 and/or DkMYC1, which have been reported to form a protein complex with each other for PA regulation, may have a central role in the differential expression of PA biosynthetic pathway genes between PCNA and non-PCNA. PMID- 29188375 TI - Tunneled pleural catheter use for pleural palliation does not increase infection rate in patients with treatment-related immunosuppression. AB - PURPOSE: Concerns for infections resulting from antineoplastic therapy-associated immunosuppression may deter referral for symptom palliation with a tunneled pleural catheter (TPC) in patients with malignant/para-malignant pleural effusions (MPE/PMPE). While rates of TPC-related infections range from 1 to 21%, those in patients receiving antineoplastic therapy with correlation to immune status has not been established. We aimed to assess TPC-related infection rates in patients on antineoplastic therapy, determine relation to immune system competency, and assess impact on the patient. METHODS: Patients with a MPE/PMPE undergoing TPC management associated with antineoplastic therapy, from 2008 to 2016, were reviewed and categorized into those with an immunocompromised versus immunocompetent immune status. RESULTS: Of the 150 patients, a TPC-related infection developed in 13 (9%): pleural space in 11 (7%) and superficial in 2 (1%). Ninety-three percent (139/150) were identified to be immunocompromised during their antineoplastic therapy. No difference in TPC-related infections was seen in patients with an immunocompromised (9%, 12/139) versus immunocompetent status (9%, 1/11); p = 0.614. The presence of a catheter-related infection did not negatively impact overall survival over a median follow-up of 144 days (interquartile range 41-341); p = 0.740. CONCLUSIONS: These results suggest that antineoplastic therapy may not significantly increase the overall risk of TPC related infections, as the rate remains low and comparable to rates in patients not undergoing antineoplastic therapy. Regardless of immune status, the presence of a catheter-related infection did not negatively impact overall survival. These results should reassure clinicians that the need to initiate antineoplastic therapy should not delay definitive pleural palliation with a TPC. PMID- 29188376 TI - The role of direct oral anticoagulants in cancer-related venous thromboembolism: a perspective beyond the guidelines. AB - Cancer-related venous thromboembolism (Wickham et al., Intern Med J 42(6):698 708, 2012) is an important source of morbidity and mortality in that population. The standard of care for the treatment of cancer-related venous thromboembolism (VTE) is a low molecular weight heparin (LMWH) for long periods of time. The favorable clinical trial results for efficacy and safety and availability of direct oral anticoagulants (DOAC) have remodeled the care and options for treatment of venous thromboembolism in the adult population. The data of cancer population-subgroup analysis of those studies have shown that DOAC are as effective and safe as conventional long-term oral anticoagulation with vitamin K antagonists (VKA). Additionally, non-controlled retrospective and prospective cohort data have been published describing efficacy and safety outcomes for the use of DOAC in cancer-related VTE. Altogether, the results from clinical studies have shown that direct oral anticoagulants may represent a treatment option for cancer-related VTE and an alternative to anticoagulation with VKA. Little is known about the patient-centered and system-based variables that determine the use of DOAC outside consensus guidelines, neither is known the impact of different anticoagulant modalities in adherence and quality of life in cancer patients. The objectives of this manuscript are to summarize the clinical trial based and cohort data of cancer patients treated with DOAC for VTE and to highlight the aspects that may influence adherent to therapy, effectiveness, and safety outcomes in the treatment of cancer-related VTE.

AB - The human amygdala consists of subdivisions contributing to various functions. However, principles of structural organization at the cellular and molecular level are not well understood. Thus, we re-analyzed the cytoarchitecture of the amygdala and generated cytoarchitectonic probabilistic maps of ten subdivisions in stereotaxic space based on novel workflows and mapping tools. This parcellation was then used as a basis for analyzing the receptor expression for 15 receptor types. Receptor fingerprints, i.e., the characteristic balance between densities of all receptor types, were generated in each subdivision to comprehensively visualize differences and similarities in receptor architecture between the subdivisions. Fingerprints of the central and medial nuclei and the anterior amygdaloid area were highly similar. Fingerprints of the lateral, basolateral and basomedial nuclei were also similar to each other, while those of the remaining nuclei were distinct in shape. Similarities were further investigated by a hierarchical cluster analysis: a two-cluster solution subdivided the phylogenetically older part (central, medial nuclei, anterior amygdaloid area) from the remaining parts of the amygdala. A more fine-grained three-cluster solution replicated our previous parcellation including a laterobasal, superficial and centromedial group. Furthermore, it helped to better characterize the paralaminar nucleus with a molecular organization in-between the laterobasal and the superficial group. The multimodal cyto- and receptor architectonic analysis of the human amygdala provides new insights into its microstructural organization, intersubject variability, localization in stereotaxic space and principles of receptor-based neurochemical differences.

AB - OBJECTIVE: Open inguinal hernia repair by Bianchi incision is a potential alternative technique for the treatment of IH. This study aims to retrospectively analyze boys with IH, who underwent open IH repair by Bianchi incision. METHODS: A total of 3300 boys (1-144 months) with IH from April 2007 to September 2015 were enrolled into this study. An open high scrotal incision (Bianchi incision) to ligate the processus proximal to the internal inguinal ring was performed in patients for IH repair. Then, all patients were followed up after 7 days, 1 month, and 1 year. Operation time, hernia recurrence, hydrocele, testicular atrophy, cosmetic results, and the satisfaction of parents were evaluated. RESULTS: Among these 3300 boys, 1662 (50.36%) and 1349 (40.88%) boys with IH were operated on the right and left side, respectively, while 289 (8.76%) patients underwent bilateral surgery. The average operation time was 13.0 +/- 2.3 min for unilateral cases and 25.2 +/- 4.2 min for bilateral cases. Furthermore, among these 3300 boys, 309 boys (9.36%) were lost to follow-up, and the remaining 2991 boys underwent a total of 3245 IH repairs. The complications included 20 recurrences who were repaired with the same technique, one wound rupture, and one acquired undescended testis. No infection, obvious scrotal hematoma, testicular atrophy, and vas deferens injury were found during the follow-up. In most instances, the scars were invisible, obtaining an excellent cosmetic effect. CONCLUSION: Inguinal hernia repair by Bianchi incision is a safe, easy and effective technique with cosmetic benefits, which could be a reliable alternative for the treatment of pediatric inguinal hernia. PMID- 29188381 TI - The effect of Wolbachia on diapause, fecundity, and clock gene expression in Trichogramma brassicae (Hymenoptera: Trichogrammatidae). AB - The short day lengths of late summer in moderate regions are used to induce diapause in various insects. Many studies have shown the maternal effect of photoperiod on diapause induction of Trichogramma wasps, but there is no study to show the relationship between photoperiodic regimes and clock genes in these useful biological control agents. Here, we investigated the role of photoperiods on diapause, fecundity, and clock gene expression (clk, cyc, cry2, per, and timeout) in asexual and sexual Trichogramma brassicae as a model insect to find any differences between two strains. Asexual strain was infected by Wolbachia, an endosymbiont bacterium. The diapause percentage was significantly higher under short days (8 h in sexual and 12 h in the asexual T. brassicae), although the diapause percentage of the sexual strain was significantly higher than the asexual one in all the photoperiods. The ANOVA revealed no significant changes between different photoperiods in the clock gene expression in the sexual strain but significant photoperiodic changes in clk, cyc, and timeout in the asexual strain. Our results showed that the mRNA levels of clock genes of asexual T. brassicae were significantly lower than those of sexual strain. The fecundity was significantly higher in the asexual strain. These results suggest that Wolbachia infection makes disturbance on the clock gene expression which consequently reduces the percentage of diapause but increases the fecundity in asexual T. brassicae. PMID- 29188382 TI - Expression patterns of duplicated snail genes in the leech Helobdella. AB - snail gene family members are zinc-finger transcription factors with key roles in morphogenesis. Involvement of snail family genes in mesoderm formation has been observed in insects and mammals. The snail genes are also involved in cell motility, neural differentiation, cell fate, survival decision, and left-right identity. The functions of snail genes have been studied primarily among ecdysozoans and deuterostomes, with relatively little work carried out in lophotrochozoans. In this study, we isolated two snail homologs (Hau-snail1 and Hau-snail2) from the leech Helobdella austinensis. We characterized the temporal and spatial expression patterns of these two genes by semi-quantitative RT-PCR and in situ hybridization. The expression of Hau-snail1 and Hau-snail2 correlates with ventral nerve cord (VNC) development, segmental mesoderm, and with a ring of cells that comes to lie at the base of the leech proboscis, respectively, showing similarity to the divergent expression of duplicated snail genes in polychaetes. Our results do not support the function of lophotrochozoan snail genes in mesoderm specification. PMID- 29188383 TI - [Postoperative care and options for scar treatment in eyelid surgery].

PMID- 29188384 TI - Long-term effects of complications and vascular comorbidity in idiopathic normal pressure hydrocephalus: a quality registry study. AB - BACKGROUND: There is little knowledge about the factors influencing the long-term outcome after surgery for idiopathic normal pressure hydrocephalus (iNPH). OBJECTIVE: To evaluate the effects of reoperation due to complications and of vascular comorbidity (hypertension, diabetes, stroke and heart disease) on the outcome in iNPH patients, 2-6 years after shunt surgery. METHODS: We included 979 patients from the Swedish Hydrocephalus Quality Registry (SHQR), operated on for iNPH during 2004-2011. The patients were followed yearly by mailed questionnaires, including a self-assessed modified Rankin Scale (smRS) and a subjective comparison between their present and their preoperative health condition. The replies were grouped according to the length of follow-up after surgery. Data on clinical evaluations, vascular comorbidity, and reoperations were extracted from the SHQR. RESULTS: On the smRS, 40% (38-41) of the patients were improved 2-6 years after surgery and around 60% reported their general health condition to be better than preoperatively. Reoperation did not influence the outcome after 2-6 years. The presence of vascular comorbidity had no negative impact on the outcome after 2-6 years, assessed as improvement on the smRS or subjective improvement of the health condition, except after 6 years when patients with hypertension and a history of stroke showed a less favorable development on the smRS. CONCLUSION: This registry-based study shows no negative impact of complications and only minor effects of vascular comorbidity on the long-term outcome in iNPH. PMID- 29188385 TI - Association of diabetes therapy-related quality of life and physical activity levels in patients with type 2 diabetes receiving medication therapy: the Diabetes Distress and Care Registry at Tenri (DDCRT 17). AB - AIM: To examine the association between diabetes therapy-related quality of life (DTR-QOL) and physical activity levels, and identify factors associated with high diabetes therapy-related quality of life. METHODS: Cross-sectional data from 2970 patients with type 2 diabetes in a Japanese diabetes registry were assessed for independent correlations between DTR-QOL (domains 1-4) and high physical activity levels. Data collected by the International Physical Activity Questionnaire were analyzed by logistic regression and adjusted for potential confounders. RESULTS: The mean patient age, BMI and HbA1c level were 65.8 years, 24.7 kg/m2 and 7.6% (58.7 mmol/mol), respectively. Univariate analysis showed that DTR-QOL domain 1, 2 and 4 scores were significantly associated with physical activity levels (p = 0.0046, p = 0.0004 and p < 0.001, respectively, but domain 3 score was not (p = 0.5073). In a multivariable-adjusted logistic regression model, odds ratios (ORs) of DTR-QOL domains 1, 3 and 4 were independently associated with high physical activity (ORs for 2nd to 4th quartile and p for trend; [domain 1] 1.16, 1.56, 1.22, p = 0.032; [domain 3] 1.45, 1.55, 1.38, p = 0.049; [domain 4] 1.09, 1.30, 1.51, p = 0.001, respectively), but domain 2 was not (ORs for 2nd to 4th quartile and p for trend; 1.19, 1.26, 1.23, p = 0.096). CONCLUSION: High diabetes therapy related QOL scores were associated with high levels of physical activity in patients with type 2 diabetes. Because this is a cross-sectional study, further study is needed to evaluate the causal association between therapy-related QOL and physical activity. PMID- 29188386 TI - The shifting paradigm of a "cure" for type 1 diabetes: is technology replacing immune-based therapies? AB - Nearly 50 years after the autoimmune nature of type 1 diabetes was discovered, no therapy has been approved to alter the course of the disease at any stage. However, during that same period, technology has been delivering tools to help patients achieve better glycemic control and reduce the burden of the disease. With the imminent arrival of fully automated artificial pancreas systems that will continue to improve control and quality of life, it appears that we are on the verge of a major technological breakthrough that will significantly impact diabetes care. These devices have such a high degree of potential that they are, at times, mentioned as a virtual cure for the disease-a first for technology in this space. As such, these devices will undoubtedly alter the research landscape in a field that has predominantly been occupied by immunotherapies. This article reviews the history of type 1 diabetes and compares and contrasts the advancements that have come from the world of technology and immunology alike at this important crossroads in care that we are currently in. PMID- 29188387 TI - Efficacy and safety of twice-daily rabeprazole maintenance therapy for patients with reflux esophagitis refractory to standard once-daily proton pump inhibitor: the Japan-based EXTEND study. AB - BACKGROUND: Rabeprazole at 10 or 20 mg twice daily (b.i.d.) has been reported to be highly effective in the treatment of proton pump inhibitor (PPI)-resistant reflux esophagitis (RE) that is refractory to the standard once-daily PPI regimen. We evaluated the efficacy and safety of rabeprazole maintenance therapy at 10 mg once daily (q.d.) or b.i.d. for longer than 8 weeks. METHODS: Patients with RE refractory to standard PPI regimens for at least 8 weeks were enrolled. They were treated with rabeprazole at 10 or 20 mg b.i.d. for 8 weeks during the open-label treatment period. After endoscopic examination, those with confirmed healing entered the subsequent double-blind maintenance therapy. During this period, the subjects were randomized to receive rabeprazole 10 mg q.d. (control) or 10 mg b.i.d. The primary endpoint was the endoscopic no-recurrence rate at Week 52. RESULTS: In total, 517 subjects entered the treatment, and 359 subjects continued on maintenance therapy. The full analysis set for central assessment included 343 subjects. The no-recurrence rate at Week 52 was significantly higher in the b.i.d. group (73.9%; p < 0.001, chi2 test) than in the q.d. group (44.8%). In particular, the b.i.d. regimen was more effective in all subgroups with Los Angeles Classification Grade B to D at treatment entry. CONCLUSIONS: In the maintenance treatment of PPI-resistant RE, rabeprazole at 10 mg b.i.d. exerted a stronger recurrence-preventing effect than 10 mg q.d. over 52 weeks. No particular safety issues were noted during long-term administration. ClinicalTrials.gov number: NCT02135107. PMID- 29188388 TI - Learning the deformation mechanism of poly(vinylidine fluoride-co chlorotrifluoroethylene): an insight into strain-induced microstructure evolution via molecular dynamics. AB - Learning the micro-mechanisms of fluorinated polymers during mechanical response is more difficult than that of common polymers due to the unique intrinsic characteristics of the fluorine element. In this paper, we applied molecular dynamics simulations to study deformation mechanisms of poly(vinylidine fluoride co-chlorotrifluoroethylene) during uniaxial tension. We analyzed the variations of individual energy components and structural distribution curves versus strain in addition to the commonly used stress-strain curves and microstructure evolutions during stretching. The elastic limit is E = 0.02, E = 0.06 is the yield point, E = 0.24 is the termination of the softening, necking occurs at 0.24 < E < 0.5, strain hardening occurs at 0.5 < E < 2.6, and E = 2.6 is the damage or brake point. The elastic behavior of the material does not rely on strain rate, the obvious effect of strain rate can be seen at the yield region and strain softening region, and the stress values are not influenced by strain rates at the softening and hardening stages. Overall, total potential energy is mainly correlated with non-bonded energy, and the proportion of DeltaEcoul overwhelms all the others. The energy components are ordered: DeltaEcoul > DeltaEvdwl > > DeltaEangle > DeltaEdihed > DeltaEbond. The chain conformation at yield point is almost unchanged compared with the pre-stretching conformation. The chain conformations at the end of strain softening changes more obviously than that at yield point. The molecular chains maintain random coil structure before strain hardening, and switch into a stretch chain conformation gradually during strain hardening. The maximum change in bond angle during the stretching process is F-C H, the largest change in bond length is the C-Cl bond, and the largest change in dihedral angle is H-C-C-H. The change of non-bonded interaction in the poly(VDF co-CTFE) system is much larger than the bonding interaction, and the main factor affecting bonding interaction is the change of angles.

AB - The non-stationary and multi-frequency nature of biomedical signal activities makes the use of time-frequency distributions (TFDs) for analysis inevitable. Time-frequency analysis provides simultaneous interpretations in both time and frequency domain enabling comprehensive explanation, presentation and interpretation of electrocardiogram (ECG) signals. The diversity of TFDs and specific properties for each type show the need to determine the best TFD for ECG analysis. In this study, a performance evaluation of five TFDs in term of ECG abnormality detection is presented. The detection criteria based on extracted features from most important ECG signal components (QRS) to detect normal and abnormal cases. This is achieved by estimating its energy concentration magnitude using the TFDs. The TFDs analyse ECG signals in one-minute interval instead of conventional time domain approach that analyses based on beat or frame containing several beats. The MIT-BIH normal sinus rhythm ECG database total records of 18 long-term ECG sampled at 128 Hz have been analysed. The tested TFDs include Dual Tree Wavelet Transform, Spectrogram, Pseudo Wigner-Ville, Choi-Williams, and Born Jordan. Each record is divided into one-minute slots, which is not considered previously, and analysed. The sample periods (slots) are randomly selected ten minutes interval for each record. This result with 99.44% detection accuracy for 15,735 ECG beats shows that Choi-Williams distribution is most reliable to be used for heart problem detection especially in automated systems that provide continuous monitoring for long time duration. PMID- 29188390 TI - A survival analysis using physique-adjusted tumor size of non-small cell lung cancer. AB - BACKGROUND: Differences in individual body sizes have not been well considered when analyzing the survival of patients with non-small cell lung cancer (NSCLC). We hypothesized that physique-adjusted tumor size is superior to actual tumor size in predicting the prognosis. METHODS: Eight hundred and forty-two patients who underwent R0 resection of NSCLC between 2005 and 2012 were retrospectively reviewed, and overall survival (OS) was evaluated. The physique-adjusted tumor size was defined as: x-adjusted tumor size = tumor size * mean value of x/individual value of x [x = height, weight, body surface area (BSA), or body mass index (BMI)]. Tumor size category was defined as <=2, 2-3, 3-5, 5-7, and >7 cm. The separation index (SEP), which is the weighted mean of the absolute value of estimated regression coefficients over the subgroups with respect to a reference group, was used to measure the separation of subgroups. RESULTS: The mean values of height, weight, BSA, and BMI were 160.7 cm, 57.6 kg, 1.59 m2, and 22.2 kg/m2, respectively. The 5-year survival rates ranged from 88-59% in the non adjusted tumor size model (SEP 1.937), from 90-57% in the height-adjusted model (SEP 2.236), from 91-52% in the weight-adjusted model (SEP 2.146), from 90-56% in the BSA-adjusted model (SEP 2.077), and from 91-51% in the BMI-adjusted model (SEP 2.169). CONCLUSIONS: The physique-adjusted tumor size can separate the survival better than the actual tumor size. PMID- 29188391 TI - Bisexual and Bidirectional: Assessing the Potential for HIV Bridging in Mozambique. AB - African men who have sex with men (MSM) frequently, and often concurrently, have female partners, raising concerns about HIV sexual bridging. We explored potential HIV transmission in Mozambique from and to female partners of MSM focusing on preferred anal sex role and circumcision status. Data collected in a respondent-driven sampling study of MSM in 2011 in Maputo and Beira. Men who had oral or anal sex with other men 12 months prior completed a questionnaire and consented for HIV testing. Statistical analysis explored demographic/risk characteristics and associations among circumcision status, anal sex with men, sexual positions during anal sex with men and vaginal or anal sex with women. We identified 326 MSM in Maputo and 237 in Beira with both male and female partners 3 months before the study. Of these, 20.8% in Maputo and 36.0% in Beira had any receptive anal sex with men 12 months prior, including 895 unprotected sexual acts with males in Maputo and 692 in Beira. Uncircumcised and exclusively insertive males, 27.7% of the sample in Maputo and 33.6% in Beira, had the most unprotected sex with females: 1159 total acts in Maputo and 600 in Beira. Sexual bridging between MSM and women likely varies geographically and is probably bi directional, occurring within a generalized epidemic where HIV prevalence is higher among reproductive-age women than MSM. Prevention strategies emphasizing correct and consistent condom use for all partners and circumcision for bisexual men should be considered. PMID- 29188392 TI - Flow perfusion rate modulates cell deposition onto scaffold substrate during cell seeding. AB - The combination of perfusion bioreactors with porous scaffolds is beneficial for the transport of cells during cell seeding. Nonetheless, the fact that cells penetrate into the scaffold pores does not necessarily imply the interception of cells with scaffold substrate and cell attachment. An in vitro perfusion system was built to relate the selected flow rate with seeding efficiency. However, the in vitro model does not elucidate how the flow rate affects the transport and deposition of cells onto the scaffold. Thus, a computational model was developed mimicking in vitro conditions to identify the mechanisms that bring cells to the scaffold from suspension flow. Static and dynamic cell seeding configurations were investigated. In static seeding, cells sediment due to gravity until they encounter the first obstacle. In dynamic seeding, 12, 120 and 600 [Formula: see text] flow rates were explored under the presence or the absence of gravity. Gravity and secondary flow were found to be key factors for cell deposition. In vitro and in silico seeding efficiencies are in the same order of magnitude and follow the same trend with the effect of fluid flow; static seeding results in higher efficiency than dynamic perfusion although irregular spatial distribution of cells was found. In dynamic seeding, 120 [Formula: see text] provided the best seeding results. Nevertheless, the perfusion approach reports low efficiencies for the scaffold used in this study which leads to cell waste and low density of cells inside the scaffold. This study suggests gravity and secondary flow as the driving mechanisms for cell-scaffold deposition. In addition, the present in silico model can help to optimize hydrodynamic-based seeding strategies prior to experiments and enhance cell seeding efficiency. PMID- 29188393 TI - Recovery in Psychosis from a Service User Perspective: A Systematic Review and Thematic Synthesis of Current Qualitative Evidence. AB - There is a growing number of qualitative accounts regarding recovery from psychosis from a service user perspective. The aim of this study was to conduct a systematic review of these qualitative accounts. A thematic synthesis was utilised to synthesise and analyse seventeen studies included in the review. Studies were included if they used a qualitative methodology to explore service users' experiences of recovery from psychosis as a primary research question. All included studies were subjected to a quality assessment. The analysis outlined three subordinate themes: the recovery journey, facilitators of recovery (e.g. faith and spirituality, personal agency and hope), and barriers to recovery (e.g. stigma and discrimination, negative effects of mental health services and medication). Recovery is an idiosyncratic process but includes key components which are important to people who experience psychosis. These should be explored within clinical practice. PMID- 29188394 TI - Resonant reshaping of colloidal clusters on a current carrying wire. AB - Colloids in confined geometries promise a path towards tailored microscopic superstructures. Yet, a major roadblock is posed by kinetically trapped states that prevent the assemblies from reaching their anticipated shapes. We investigate magnetic colloids trapped on a cylindrical surface of a current carrying wire. If kinetic traps could be avoided the wire's surface would act as an ideal mold for colloidal rings and helical fibers. We devise here a way to dynamically shake down the clusters and avoid kinetic traps in their energy landscape. A low frequency magnetic modulation wave around the wire axis effectively eliminates defects from the clusters and stretches them into slender rings and helical filaments. A theoretical model is developed that qualitatively explains the observed resonant reshaping response of clusters.

PMID- 29188396 TI - Cerebrovascular Hemodynamics During the Practice of Bhramari Pranayama, Kapalbhati and Bahir-Kumbhaka: An Exploratory Study. AB - Various pranayama techniques are known to produce different physiological effects. We evaluated the effect of three-different pranayama techniques on cerebrovascular hemodynamics. Eighteen healthy volunteers with the mean +/- standard deviation age of 23.78 +/- 2.96 years were performed three-different pranayama techniques: (1) Bhramari, (2) Kapalbhati and (3) Bahir-Kumbhaka in three-different orders. Continuous transcranial Doppler (TCD) monitoring was performed before, during and after the pranayama techniques. TCD parameters such as peak systolic velocity, end diastolic velocity (EDV), mean flow velocity (MFV) and pulsatility index (PI) of right middle cerebral artery were recorded. Practice of Kapalbhati showed significant reductions in EDV and MFV with significant increase in PI while, Bahir-Kumbhaka showed significant increase in EDV and MFV with significant reduction in PI. However, no such significant changes were observed in Bhramari pranayama. Various types of pranayama techniques produce different cerebrovascular hemodynamic changes in healthy volunteers. PMID- 29188397 TI - Comparison of machine learning and semi-quantification algorithms for (I123)FP CIT classification: the beginning of the end for semi-quantification? AB - BACKGROUND: Semi-quantification methods are well established in the clinic for assisted reporting of (I123) Ioflupane images. Arguably, these are limited diagnostic tools. Recent research has demonstrated the potential for improved classification performance offered by machine learning algorithms. A direct comparison between methods is required to establish whether a move towards widespread clinical adoption of machine learning algorithms is justified. This study compared three machine learning algorithms with that of a range of semi quantification methods, using the Parkinson's Progression Markers Initiative (PPMI) research database and a locally derived clinical database for validation. Machine learning algorithms were based on support vector machine classifiers with three different sets of features: Voxel intensities Principal components of image voxel intensities Striatal binding radios from the putamen and caudate. Semi quantification methods were based on striatal binding ratios (SBRs) from both putamina, with and without consideration of the caudates. Normal limits for the SBRs were defined through four different methods: Minimum of age-matched controls Mean minus 1/1.5/2 standard deviations from age-matched controls Linear regression of normal patient data against age (minus 1/1.5/2 standard errors) Selection of the optimum operating point on the receiver operator characteristic curve from normal and abnormal training data Each machine learning and semi quantification technique was evaluated with stratified, nested 10-fold cross validation, repeated 10 times. RESULTS: The mean accuracy of the semi quantitative methods for classification of local data into Parkinsonian and non Parkinsonian groups varied from 0.78 to 0.87, contrasting with 0.89 to 0.95 for classifying PPMI data into healthy controls and Parkinson's disease groups. The machine learning algorithms gave mean accuracies between 0.88 to 0.92 and 0.95 to 0.97 for local and PPMI data respectively. CONCLUSIONS: Classification performance was lower for the local database than the research database for both semi-quantitative and machine learning algorithms. However, for both databases, the machine learning methods generated equal or higher mean accuracies (with lower variance) than any of the semi-quantification approaches. The gain in performance from using machine learning algorithms as compared to semi quantification was relatively small and may be insufficient, when considered in isolation, to offer significant advantages in the clinical context. PMID- 29188398 TI - Trastuzumab combined with doublet or single-agent chemotherapy as first-line therapy for HER2-positive metastatic breast cancer. AB - PURPOSE: To investigate the efficacy and safety of doublet versus single-agent chemotherapy (CT) plus trastuzumab (H) as first-line therapy for human epidermal growth factor 2 receptor (HER2)-positive metastatic breast cancer (MBC). METHODS: We searched for randomized clinical trials (RCTs) that evaluated the treatment effects of single-agent or doublet CT+H as first-line therapies for HER2-positive MBC. The main outcomes measured for this study included the overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). A meta analysis and trial sequential analysis (TSA) were performed, and the study quality was evaluated using the GRADE framework. The PROSPERO registry number of our analysis is CRD42016043766. RESULTS: The results from four RCTs including 1044 participants were pooled. Moderate-quality evidence indicated that compared with single-agent CT+H, doublet CT+H correlated better with prolonged PFS (hazard ratio [HR] 0.69, 95% confidence interval [CI] 0.63-0.75, P < 0.0001) and OS (HR = 0.90, 95% CI 0.88-0.92, P < 0.0001). However, moderate-quality evidence revealed no significant difference between the two regimens regarding the ORR (relative risk [RR] = 1.07, 95% CI 0.98-1.17, P = 0.157), which was confirmed by TSA, indicating that the cumulative Z-curve entered the futility area. Moderate quality evidence indicated that treatment-related grade 3 or 4 toxicities of thrombocytopenia (RR = 4.08, P = 0.000), nausea/vomiting (RR = 4.26, P = 0.002), diarrhea (RR = 2.81, P = 0.002), and stomatitis (RR = 5.02, P = 0.003) were observed more frequently with doublet CT+H than with single-agent CT+H. CONCLUSIONS: Compared with single-agent CT, the combination of doublet CT with trastuzumab as first-line therapy for HER2-positive MBC is associated with longer PFS and OS, but more treatment-related grade 3 or 4 toxicities. Therefore, doublet CT appears to be an appropriate regimen for HER2-positive MBC with a good performance status.

AB - Tuckerella japonica Ehara (Acari: Tuckerellidae) feeds on predigested plant cells beneath exposed periderm tissue of 1- to 3+-year-old stems of Camellia sinensis (L.) O. Kuntze (Theaceae) where longitudinal bark splitting occurs. Control samples from these tissues were compared with areas fed upon by T. japonica adults and immatures to characterize types of cellular injury. Stylet diameters ranged from 1.6 to 2.3 um and were consistent with observed stylet punctures in the stems. Mite saliva was injected along tracts within the cortical tissue and resulted in cell wall disruption, collapsed cells and, in older tissue, hyperplasia. The range of potential stylet penetration into plant tissues was from 92 to 150 um. Tuckerella japonica injects saliva in the cortical tissues. The paired stylet lengths would allow for possible injection of saliva into the upper areas of phloem tissue but not in the cambium area of wood exposed by splitting of the outer epidermis. PMID- 29188399 TI - The alcoholic brain: neural bases of impaired reward-based decision-making in alcohol use disorders. AB - Neuroeconomics is providing insights into the neural bases of decision-making in normal and pathological conditions. In the neuropsychiatric domain, this discipline investigates how abnormal functioning of neural systems associated with reward processing and cognitive control promotes different disorders, and whether such evidence may inform treatments. This endeavor is crucial when studying different types of addiction, which share a core promoting mechanism in the imbalance between impulsive subcortical neural signals associated with immediate pleasurable outcomes and inhibitory signals mediated by a prefrontal reflective system. The resulting impairment in behavioral control represents a hallmark of alcohol use disorders (AUDs), a chronic relapsing disorder characterized by excessive alcohol consumption despite devastating consequences. This review aims to summarize available magnetic resonance imaging (MRI) evidence on reward-related decision-making alterations in AUDs, and to envision possible future research directions. We review functional MRI (fMRI) studies using tasks involving monetary rewards, as well as MRI studies relating decision-making parameters to neurostructural gray- or white-matter metrics. The available data suggest that excessive alcohol exposure affects neural signaling within brain networks underlying adaptive behavioral learning via the implementation of prediction errors. Namely, weaker ventromedial prefrontal cortex activity and altered connectivity between ventral striatum and dorsolateral prefrontal cortex likely underpin a shift from goal-directed to habitual actions which, in turn, might underpin compulsive alcohol consumption and relapsing episodes despite adverse consequences. Overall, these data highlight abnormal fronto-striatal connectivity as a candidate neurobiological marker of impaired choice in AUDs. Further studies are needed, however, to unveil its implications in the multiple facets of decision-making. PMID- 29188401 TI - Drought stress promotes the colonization success of a herbivorous mite that manipulates plant defenses. AB - Climate change is expected to bring longer periods of drought and this may affect the plant's ability to resist pests. We assessed if water deficit affects the tomato russet mite (TRM; Aculops lycopersici), a key tomato-pest. TRM thrives on tomato by suppressing the plant's jamonate defenses while these defenses typically are modulated by drought stress. We observed that the TRM population grows faster and causes more damage on drought-stressed plants. To explain this observation we measured several nutrients, phytohormones, defense-gene expression and the activity of defensive proteins in plants with or without drought stress or TRM. TRM increased the levels of total protein and several free amino acids. It also promoted the SA-response and upregulated the accumulation of jasmonates but down-regulated the downstream marker genes while promoting the activity of cysteine-but not serine-protease inhibitors, polyphenol oxidase and of peroxidase (POD). Drought stress, in turn, retained the down regulation of JA-marker genes and reduced the activity of serine protease inhibitors and POD, and altered the levels of some free-amino acids. When combined, drought stress antagonized the accumulation of POD and JA by TRM and synergized accumulation of free sugars and SA. Our data show that drought stress interacts with pest-induced primary and secondary metabolic changes and promotes pest performance. PMID- 29188402 TI - Development and characterisation of a large diameter decellularised vascular allograft. AB - The aims of this study were to develop a biological large diameter vascular graft by decellularisation of native human aorta to remove the immunogenic cells whilst retaining the essential biomechanical, and biochemical properties for the ultimate benefit of patients with infected synthetic grafts. Donor aortas (n = 6) were subjected to an adaptation of a propriety decellularisation process to remove the cells and acellularity assessed by histological analysis and extraction and quantification of total DNA. The biocompatibility of the acellular aortas was determined using standard contact cytotoxicity tests. Collagen and denatured collagen content of aortas was determined and immunohistochemistry was used to determine the presence of specific extracellular matrix proteins. Donor aortas (n = 6) were divided into two, with one half subject to decellularisation and the other half retained as native tissue. The native and decellularised aorta sections were then subject to uniaxial tensile testing to failure [axial and circumferential directions] and suture retention testing. The data was compared using a paired t-test. Histological evaluation showed an absence of cells in the treated aortas and retention of histoarchitecture including elastin content. The decellularised aortas had less than 15 ng mg-1 total DNA per dry weight (mean 94% reduction) and were biocompatible as determined by in vitro contact cytotoxicity tests. There were no gross changes in the histoarchitecture [elastin and collagen matrix] of the acellular aortas compared to native controls. The decellularisation process also reduced calcium deposits within the tissue. The uniaxial tensile and suture retention testing revealed no significant differences in the material properties (p > 0.05) of decellularised aorta. The decellularisation procedure resulted in minimal changes to the biological and biomechanical properties of the donor aortas. Acellular donor aorta has excellent potential for use as a large diameter vascular graft. PMID- 29188403 TI - Maternal Acceptance Moderates Fear Ratings and Avoidance Behavior in Children. AB - Avoidance is a hallmark feature of anxiety disorders, and avoidance-related impairment is often key to meeting diagnostic criteria. In children and adolescents with anxiety disorders, levels of avoidance vary considerably. Using a novel motion-tracking measure of avoidance behavior, we examined whether maternal acceptance, characterized by warm and accepting responses to child feelings and behaviors, moderates the association between fear of spiders and behavioral avoidance of spider stimuli in 103 clinically anxious children. As hypothesized, maternal acceptance significantly moderated children's avoidance behavior. Child's fear of spiders was significantly associated with behavioral avoidance when mothers were low in acceptance, as rated by either mothers or children. When mothers were high in acceptance, as rated by either mothers or children, child self-rated fear of spiders was not significantly associated with child avoidance. These are the first results to empirically demonstrate the moderating role of maternal acceptance in anxious children's avoidance behavior. PMID- 29188404 TI - Enhanced IgG1 production by overexpression of nuclear factor kappa B inhibitor zeta (NFKBIZ) in Chinese hamster ovary cells. AB - Several engineering strategies have been employed to improve the production of therapeutic recombinant proteins in Chinese hamster ovary (CHO) cell lines. We have focused on unfolded protein response-based engineering and reported that ATF4 overexpression increases protein production. In this study, transcriptome analysis of ATF4-overexpressed CHO cells was performed using high-coverage expression profiling, to search for another key factor contributing to recombinant protein production. We observed the upregulated expression of transcription factor, nuclear factor (NF)-kappa-B inhibitor zeta (NFKBIZ or Ikappabzeta), in ATF4-overexpressed cells. A total of 1917 bp of CHO NFKBIZ cDNA was cloned, and two stable cell lines overexpressing NFKBIZ were constructed. We investigated the effects of NFKBIZ on IgG1 production in CHO cells. Although the two stable cell lines, NFKBIZ-A and -B, had the opposite phenotypes in cell growth, the specific IgG1 production rate of both cell lines was enhanced by 1.2 1.4-fold. In the NFKBIZ-A cell line, the synergistic effect between enhanced viable cell density and improved specific IgG1 production rate brought about a large increase in the final IgG1 titer. Luciferase-based NF-kappaB signaling assay results suggest that altered p50/p50 signaling seems to be due to the opposite phenotypes in cell growth. No difference was observed in the translational levels and intracellular assembly states of IgG1 between mock and two NFKBIZ cell lines, indicating that the secretion machinery of correctly folded IgG1 was enhanced in NFKBIZ-overexpressing cell lines. PMID- 29188405 TI - Promoting effects of adipose-derived stem cells on breast cancer cells are reversed by radiation therapy. AB - Partial breast irradiation of early breast cancer patients after lumpectomy and the use of endogenous adipose tissue (AT) for breast reconstruction are promising applications to reduce the side effects of breast cancer therapy. This study tries to investigate the possible risks associated with these therapeutic approaches. It also examines the influence of adipose derived stem cells (ADSCs) as part of the breast cancer microenvironment, and endogenous AT on breast cancer cells following radiation therapy. ADSCs, isolated from human reduction mammoplasties of healthy female donors, exhibited multilineage capacity and specific surface markers. The promoting effects of ADSCs on the growth and survival fraction of breast cancer cells were reversed by treatment with high (8 Gy) or medium (2 Gy) radiation doses. In addition, a suppressing influence on breast cancer growth could be detected by co-culturing with irradiated ADSCs (8 Gy). Furthermore the clonogenic survival of unirradiated tumor cells was reduced by medium of irradiated ADSCs. In conclusion, radiation therapy changed the interactions of ADSCs and breast cancer cells. On the basis of our work, the importance of further studies to exclude potential risks of ADSCs in regenerative applications and radiotherapy has been emphasized.

AB - Originally premiering in 1963, the BBC television series Doctor Who has long been criticized for essentializing colonial scenarios and failing to address issues of race and post-colonial realities. As a white male with the privilege to explore time and space, the titular Doctor stands in contrast to his human companion Martha Jones, a Black woman who represents the first and only main character in the show to be a medical professional of color. The relationship between the Doctor and Martha inherently demands an exploration of the meaning of doctorhood. In studying the ways in which these characters embody the idea of "doctor," we examine how race structures their approach to medicine, heroism, and colonialism. Whereas the Doctor personifies the figure of colonizer and post-colonial white savior, Martha emerges as a radical figure whose doctorhood potentially challenges and dismantles the colonial history of medicine. Through Afrofuturist and Afrosurrealist lenses, Martha represents a potentially subversive figure who offers a visionary medicine rooted in social justice.

AB - BACKGROUND: Delta-like ligand 4-Notch (DLL4-Notch) signaling contributes to the maintenance of chemotherapy-resistant cancer stem cells and tumor vasculature. OBJECTIVE: This phase IB trial of demcizumab, an IgG2 humanized monoclonal antibody directed against DLL4, was undertaken to determine its maximum tolerated dose, safety, immunogenicity, preliminary efficacy, pharmacokinetics, and pharmacodynamics, combined with standard chemotherapy. PATIENTS AND METHODS: Forty-six treatment-naive patients with metastatic non-squamous non-small cell lung cancer (NSCLC) were enrolled in this open-label, dose-escalation study using a standard 6 + 6 design. Demcizumab (2.5, 5.0, and 7.5 mg/kg) was given once every 3 weeks with standard doses of pemetrexed and carboplatin using a continuous (six cycles followed by demcizumab maintenance) or a truncated demcizumab regimen (four cycles followed by pemetrexed maintenance). RESULTS: Initially, continuous demcizumab was given until progression but two patients developed grade 3 pulmonary hypertension and congestive heart failure after eight or more infusions. Thereafter, 23 patients were treated with a truncated regimen of demcizumab, which was not associated with any grade 3 or greater cardiopulmonary toxicity. Common adverse events were hypertension, raised brain natriuretic peptide, and those expected from carboplatin and pemetrexed alone. Twenty of 40 evaluable patients (50%) had objective tumor responses. In peripheral blood, demcizumab treatment modulated the expression of genes regulating Notch signaling and angiogenesis, and achieved concentrations exceeding those saturating DLL4 binding. CONCLUSIONS: This study has identified a truncated dosing regimen and recommended phase II dose of demcizumab (5 mg/kg q3 weekly *4) for subsequent clinical evaluation in combination with standard carboplatin and pemetrexed chemotherapy.

AB - Correction to: J Youth Adolescence (2017) 46:1351-1369. 10.1007/s10964-016-0601 4. PMID- 29188410 TI - Developmental Pathways from Parental Socioeconomic Status to Adolescent Substance Use: Alternative and Complementary Reinforcement. AB - Although lower socioeconomic status has been linked to increased youth substance use, much less research has determined potential mechanisms explaining the association. The current longitudinal study tested whether alternative (i.e., pleasure gained from activities without any concurrent use of substances) and complementary (i.e., pleasure gained from activities in tandem with substance use) reinforcement mediate the link between lower socioeconomic status and youth substance use. Further, we tested whether alternative and complementary reinforcement and youth substance use gradually unfold over time and then intersect with one another in a cascading manner. Potential sex differences are also examined. Data were drawn from a longitudinal survey of substance use and mental health among high school students in Los Angeles. Data collection involved four semiannual assessment waves beginning in fall 2013 (N = 3395; M baseline age = 14.1; 47% Hispanic, 16.2% Asian, 16.1% multiethnic, 15.7% White, and 5% Black; 53.4% female). The results from a negative binomial path model suggested that lower parental socioeconomic status (i.e., lower parental education) was significantly related to an increased number of substances used by youth. The final path model revealed that the inverse association was statistically mediated by adolescents' diminished engagement in pleasurable substance-free activities (i.e., alternative reinforcers) and elevated engagement in pleasurable activities paired with substance use (i.e., complementary reinforcers). The direct effect of lower parental education on adolescent substance use was not statistically significant after accounting for the hypothesized mediating mechanisms. No sex differences were detected. Increasing access to and engagement in pleasant activities of high quality that do not need a reinforcement enhancer, such as substances, may be useful in interrupting the link between lower parental socioeconomic status and youth substance use. PMID- 29188411 TI - Callous-Unemotional Traits and Autonomic Functioning in Toddlerhood Interact to Predict Externalizing Behaviors in Preschool. AB - Callous-unemotional (CU) traits are one meaningful risk factor which helps to explain heterogeneity in the emergence of externalizing behavior problems. While the extant literature demonstrates links between early CU traits and later externalizing problems, there is a dearth of research examining for whom early CU traits confer risk. Data from a longitudinal study (n = 108) were used to examine the extent to which parasympathetic functioning moderated links between CU traits in toddlerhood (m age = 24.99 months) and externalizing behavior problems at preschool-age (m age = 51 months). Neither CU traits nor parasympathetic functioning at age 2 directly predicted later externalizing behaviors. However, results show that high levels of CU traits predict elevated externalizing behavior problems, but only for toddlers exhibiting either high baseline respiratory sinus arrhythmia (RSA) or little to no RSA suppression in response to a fear stimulus. PMID- 29188412 TI - Drug-related problems identified during geriatric medication review in the community pharmacy. AB - Background In line with the changing role of community pharmacists, we describe here a standardised procedure for detecting DRPs in elderly patients for use in community pharmacies. Objectives The primary aim was to describe the number and type of DRPs identified by community pharmacists in elderly patients. Secondary aims were to determine the number and type of associated pharmacist interventions (PIs) that were transmitted to the prescribers, and to identify risk factors associated with the occurrence of a PI. Setting Community pharmacies. Methods In this prospective, multicentre study, pharmacists received patients aged 65 and over. During a 30-min interview with patients who agreed to participate, patient characteristics were recorded such as age, weight, height, frailty (using the Short Emergency Geriatric Assessment grid), estimated renal function and compliance with treatment assessed by the Girerd scale. Main outcome measure DRPs characteristics. Results A total of 892 patients agreed to participate in 55 pharmacies. Among them 334 DRPs were identified and were associated with 259 PIs. Eighty-nine PIs of 259 were sent to the prescribing physicians; 70 (78%) were implemented by the general practitioner. Factors associated with the occurrence of a DRP are compliance problems [odds ratio (OR) = 1.8, 95% confidence interval (CI) (1.26-2.58)], frailty [OR = 1.3, 95% CI (1.01-1.66)], number of prescribed drugs per day [OR = 1.46, 95% CI (1.02-2.07)] and GFR < 60 mL/min [OR = 1.49, 95% CI (1.01-2.2)]. Conclusion This is the first standardised pharmaceutical assessment dedicated to the elderly carried out by community pharmacists in France. If implemented, it could help to find drug-related problems, identify frail elderly patients and ultimately decrease their exposure to iatrogenic medication errors. PMID- 29188413 TI - Bioaccessibility of Phenolic Compounds and Antioxidant Capacity of Chia (Salvia hispanica L.) Seeds. AB - The aim of this work was to evaluate (i) the phenol and flavonoid recovery and bioaccessibility indexes and (ii) the antioxidant activity of both types of non defatted and defatted chia seeds during the in vitro gastrointestinal digestion. The ground samples were subjected to in vitro simulated gastrointestinal digestion, and the resultant fractions were extracted and subjected to spectrophotometric assays. The results pointed to increasing concentrations of polyphenolic compounds during digestion, although only a low-medium percentage of phenols and a low percentage of flavonoids were available for absorption in the intestinal tract. In addition, the high level of fats seemed to have a negative effect on the bioaccessibility of flavonoids. Further studies should be undertaken to better understand the stabilization of the bioactive compounds of chia and to improve their bioaccessibility. Meanwhile, the present study represents a solid base for studying the bioavailability of bioactive compounds of chia seeds. PMID- 29188414 TI - Velocity-pressure loops for continuous assessment of ventricular afterload: influence of pressure measurement site. AB - VPloop, the graphical representation of pressure versus velocity, and its characteristic angles, GALA and beta, can be used to monitor cardiac afterload during anesthesia. Ideally VPloop should be measured from pressure and velocity obtained at the same arterial location but standard of care usually provide either radial or femoral pressure waveforms. The purpose of this study was to look at the influence of arterial sites and the use of a transfer function (TF) on VPloop and its related angles. Invasive pressure signals were recorded in 25 patients undergoing neuroradiology intervention under general anesthesia with transesophageal flow velocity monitoring. Pressures were recorded in the descending thoracic aorta, abdominal aorta, femoral and radial arteries. We compared GALA and beta from VPloops generated from each location and in high and low risk patients. GALA was similar in the central locations (55 degrees [49-63], 52 degrees [47-61] and 54 degrees [45-62] from descending thoracic to femoral artery, median[interquartile], p = 0.10), while there was a difference in beta angle (16 degrees [4-27] to 8 degrees [3-15], p < 0.0001). GALA and beta obtained from radial waveforms were different (39 degrees [31-47] compared to 46 degrees [36-54] and 6 degrees [2-14] compared to 16 degrees [4-27] for GALA and beta angles respectively, p < 0.001) which was corrected by the use of a TF (45 degrees [32-55] and 17 degrees [5-28], p = ns). GALA and beta are underestimated when measured with a radial catheter. Using pressure waveforms from femoral locations alters VPloops, GALA and beta in a smaller extend. The use of a TF on radial pressure allows to correctly plot VPloops and their characteristic angles for routine clinical use. PMID- 29188415 TI - Botanical origin of Mei-gui Hua in Chinese markets. AB - The petals or buds of Rosa species have been used as an important Chinese crude drug called "Mei-gui Hua" and also an ingredient for herbal tea in China. The 15 flavonol glycosides in 34 commercially available "Mei-gui Hua" were quantitatively determined by UPLC, and the data were compared with those of known Rosa sp. belong to Cinnamomeae, Gallicanae, Caninae and Synstylae by principal component analysis for the estimation of original plants of these "Mei-gui Hua". Seven samples were classified into two groups (Types A and B) composed of species in Gallicae and Synstilae and 11 samples into a group (Type D) composed of species in Cinnamomeae. Six samples were plotted among Types B, C and D. However, nine samples were shown to form a new group (Type F), and the original plants of these samples were assumed to be more complex hybrids of Rosa species including other sections than Cinnamomeae, Gallicanae, Caninae and Synstylae. This method must be useful and convenient to estimate the origin of crude drug "Mei-gui Hua" commercially available in markets. The results of this study also demonstrated that "Mei-gui Hua" commercially available in Chinese market must be prepared from hybrids of various species of Rosa, and it is not reasonable to assign only R. rugosa as scientific name of the origin plants. PMID- 29188416 TI - Production of an emericellin and its analogues as fungal biological responses for Shimbu-to extract. AB - This research examined the production of fungal metabolites as a biological response to Kampo medicines. Shimbu-to (SMB) is a Kampo medicine composed of five herbal components: peony root (Shakuyaku), ginger (Shokyo), processed aconite root (Bushi), Poria sclerotium (Bukuryo), and Atractylodes lancea rhizomes (Sojutsu). High-performance liquid chromatography (HPLC) analysis of the fungus Aspergillus nidulans CBS 112.46 incubated in potato dextrose broth supplemented with SMB extract revealed emericellin (2) as the major peak and new xanthone analogues 24-hydroxyshamixanthone (1), shamixanthone (3), epishamixanthone (4), pre-shamixanthone (5), and variecoxanthone A (6) as minor peaks. The structure of 1 was determined by detailed analysis of 1D-NMR, 2D-NMR, and MS data. The results suggest that SMB extract regulates the biosynthesis of emericellin and its analogues in A. nidulans. Further investigations revealed that glucose induces the biosynthesis of emericellin and its analogues in A. nidulans in a concentration-dependent manner. PMID- 29188417 TI - Simultaneous determination of fast and slow dynamics in molecules using extreme CPMG relaxation dispersion experiments. AB - Molecular dynamics play a significant role in how molecules perform their function. A critical method that provides information on dynamics, at the atomic level, is NMR-based relaxation dispersion (RD) experiments. RD experiments have been utilized for understanding multiple biological processes occurring at micro to-millisecond time, such as enzyme catalysis, molecular recognition, ligand binding and protein folding. Here, we applied the recently developed high-power RD concept to the Carr-Purcell-Meiboom-Gill sequence (extreme CPMG; E-CPMG) for the simultaneous detection of fast and slow dynamics. Using a fast folding protein, gpW, we have shown that previously inaccessible kinetics can be accessed with the improved precision and efficiency of the measurement by using this experiment. PMID- 29188419 TI - Comparison of the outcome between unilateral and bilateral open wedge high tibial osteotomy in the bilateral varus knees. AB - INTRODUCTION: Bilateral open wedge high tibial osteotomy (OWHTO) can be performed in a staged manner to enable the healing and rehabilitation of each limb separately after surgery. However, the effects of staged bilateral OWHTO on the pattern of recovery and changes over time for each limb have not been established. Additionally, there is a lack of information regarding the optimal timing for staged surgery. METHODS: Twenty-two patients (44 knees) in the bilateral OWHTO group and 42 patients (42 knees) in the unilateral OWHTO group were analyzed. Clinical and radiological results were evaluated and compared between the two groups. For the alignment change assessment, the hip-knee-ankle (HKA) angle and weight-bearing line (WBL) ratio were measured preoperatively and at postoperative 6 weeks, 3 months, 6 months, and 1 year. RESULTS: The correction loss of HKA angle in the bilateral OWHTO group was significantly larger than that in the unilateral OWHTO group (0.5 degrees +/- 1.4 degrees vs 1.3 degrees +/- 2.0 degrees , p = 0.049). The correction loss of WBL ratio was significantly greater in the patients with staged bilateral OWHTO within a 3-month interval compared to those with staged bilateral OWHTO in an interval longer than 3 months (WBL ratio; 7.5% vs 2.1%, p = 0.01). There was no significant difference in the clinical scores and range of motion at the last follow-up. CONCLUSION: The smaller loss of correction in the unilateral OWHTO group occurred compared to the bilateral OWHTO group. Additionally, surgeons should keep in mind that the amount of correction loss may be greater if staged bilateral OWHTO is performed at intervals of 3 months or less. PMID- 29188418 TI - Imaging of Nanoparticle Distribution to Assess Treatments That Alter Delivery. AB - Molecular imaging is a vital tool to non-invasively measure nanoparticle delivery to solid tumors. Despite the myriad of nanoparticles studied for cancer, successful applications of nanoparticles in humans is limited by inconsistent and ineffective delivery. Successful nanoparticle delivery in preclinical models is often attributed to enhanced permeability and retention (EPR)-a set of conditions that is heterogeneous and transient in patients. Thus, researchers are evaluating therapeutic strategies to modify nanoparticle delivery, particularly treatments which have demonstrated effects on EPR conditions. Imaging nanoparticle distribution provides a means to measure the effects of therapeutic intervention on nanoparticle delivery to solid tumors. This review focuses on the utility of imaging to measure treatment-induced changes in nanoparticle delivery to tumors and provides preclinical examples studying a broad range of therapeutic interventions. PMID- 29188420 TI - A lateral retinacular release during total knee arthroplasty changes femorotibial kinematics: an in vitro study. AB - INTRODUCTION: Lateral retinacular release (LRR) is a common procedure during total knee arthroplasty (TKA), especially if patellar maltracking is observed intraoperatively. The impact of LRR on patellofemoral kinematics is well examined, but the influence on femorotibial kinematics requires more elucidation. Therefore, the aim of this study was to evaluate the effects of LRR on femorotibial kinematics in vitro. MATERIALS AND METHODS: A fixed bearing TKA was implanted in six human knee specimens. Femorotibial kinematics were measured dynamically through the use of a custom-constructed knee rig which flexes the knee from 20 degrees to 120 degrees under weight bearing conditions. Measurements were performed before and after LRR. LRR was performed completely including transection of synovium, retinaculum and tractus fibers. For the registration of tibiofemoral kinematics a 3-dimensional-ultrasound-based motion analysis system was used. RESULTS: LRR revealed a significant reduction of femoral rollback at the lateral compartment (9.4 +/- 5.0 vs 7.8 +/- 9.4 mm; p < 0.01), whereas the present decrease of femoral rollback at the medial compartment was not significant (3.4 +/- 4.7 vs 2.3 +/- 5.9 mm; p = 0.34). Accordingly, LRR significantly reduced internal rotation of the tibia (0.8 degrees ; p < 0.01). CONCLUSION: The results suggest that LRR significantly decreases lateral femoral rollback as well as internal rotation of the tibia, probably by changing the tension of the iliotibial band. When performing a LRR in clinical routine, surgeons should be aware of altering not only patellofemoral kinematics but also the femorotibial kinematics. PMID- 29188421 TI - Arthroscopic partial meniscectomy in young patients with symptomatic discoid lateral meniscus: an average 10-year follow-up study. AB - INTRODUCTION: The aim of this study is to evaluate mid-to-long-term clinical and radiological outcomes after an arthroscopic partial meniscectomy for symptomatic discoid lateral meniscus (DLM) in young patients and to determine whether degeneration of the residual meniscus and articular cartilage progresses during the follow-up period using magnetic resonance imaging (MRI). MATERIALS AND METHODS: We retrospectively reviewed patients aged <= 40 years at surgery who underwent arthroscopic partial meniscectomy for symptomatic DLM and were followed up for >= 5 years. Lysholm knee scores and reoperation rates were assessed as clinical outcomes. Factors that affect clinical outcomes were evaluated. Tapper Hoover classification and femorotibial angle were used for radiological assessment. The degree of degeneration of articular cartilages and residual meniscus was evaluated using preoperative and follow-up MRIs. RESULTS: A total of 73 knees (66 patients) were enrolled. The mean follow-up period was 10.0 years. The mean follow-up Lysholm knee score was 84.2 +/- 14.5, and the reoperation rate was 32.9%. Follow-up Lysholm knee scores were related to duration of symptoms prior to surgery (beta = - 0.129, P = 0.003) and femorotibial angle at the last follow-up (beta = 1.362, P = 0.045). On simple radiographs, progression of arthritis of the lateral compartment was observed in 68.5% (49 knees). In MRI analyses, degeneration of the residual meniscus progressed in 52.9% (34 knees) (P < 0.001), and significant changes in modified Yulish scores were observed in both lateral femoral and tibial condyles (P < 0.001, both condyles). CONCLUSIONS: After an arthroscopic partial meniscectomy for symptomatic DLM, unfavorable clinical outcomes were shown in > 30% of the patients during a mean follow-up of 10.0 years. Clinical outcomes based on the patient-reported outcome measures were related to durations of symptoms prior to surgery and alignment at the last follow-up. In radiological and MRI assessments, progression of degeneration of articular cartilages in the lateral compartments of the knees and residual menisci was observed. PMID- 29188422 TI - Climbing plants: attachment adaptations and bioinspired innovations. AB - Climbing plants have unique adaptations to enable them to compete for sunlight, for which they invest minimal resources for vertical growth. Indeed, their stems bear relatively little weight, as they traverse their host substrates skyward. Climbers possess high tensile strength and flexibility, which allows them to utilize natural and manmade structures for support and growth. The climbing strategies of plants have intrigued scientists for centuries, yet our understanding about biochemical adaptations and their molecular undergirding is still in the early stages of research. Nonetheless, recent discoveries are promising, not only from a basic knowledge perspective, but also for bioinspired product development. Several adaptations, including nanoparticle and adhesive production will be reviewed, as well as practical translation of these adaptations to commercial applications. We will review the botanical literature on the modes of adaptation to climb, as well as specialized organs-and cellular innovations. Finally, recent molecular and biochemical data will be reviewed to assess the future needs and new directions for potential practical products that may be bioinspired by climbing plants. PMID- 29188423 TI - Augmented marker tracking for peri-acetabular osteotomy surgery. AB - OBJECTIVE: To develop a hybrid augmented marker-based navigation system for acetabular reorientation during peri-acetabular osteotomy (PAO). METHODS: The system consists of a tracking unit attached to the patient's pelvis, augmented marker attached to the acetabular fragment and a host computer to do all the computations and visualization. The augmented marker is comprised of an external planar Aruco marker facing toward the tracking unit and an internal inertial measurement unit (IMU) to measure its orientation. The orientation output from the IMU is sent to the host computer. The tracking unit streams a live video of the augmented marker to the host computer, where the planar marker is detected and its pose is estimated. A Kalman filter-based sensor fusion combines the output from marker tracking and the IMU. We validated the proposed system using a plastic bone study and a cadaver study. Every time, we compared the inclination and anteversion values measured by the proposed system to those from a previously developed optical tracking-based navigation system. RESULTS: Mean absolute differences for inclination and anteversion were 1.34 ([Formula: see text]) and 1.21 ([Formula: see text])[Formula: see text], respectively, for the cadaver study. Mean absolute differences were 1.63 ([Formula: see text]) and 1.55 ([Formula: see text])[Formula: see text] for inclination and anteversion for the plastic bone study. In both validation studies, very strong correlations were observed. CONCLUSION: We successfully demonstrated the feasibility of our system to measure the acetabular orientation during PAO. PMID- 29188424 TI - Increase in Mitochondrial Biogenesis in Neuronal Cells by RNS60, a Physically Modified Saline, via Phosphatidylinositol 3-Kinase-Mediated Upregulation of PGC1alpha. AB - This study highlights a novel approach to upregulate mitochondrial biogenesis in neuronal cells. RNS60 is a 0.9% saline solution containing oxygenated nanobubbles that is generated by subjecting normal saline to Taylor-Couette-Poiseuille (TCP) flow under elevated oxygen pressure. RNS60, but not NS (normal saline), PNS60 (saline containing a comparable level of oxygen without the TCP modification), or RNS10.3 (TCP-modified normal saline without excess oxygen), increased the expression of Nrf1, Tfam, Mcu, and Tom20 (genes associated with mitochondrial biogenesis) and upregulated mitochondrial biogenesis in MN9D dopaminergic neuronal cells. Similarly RNS60 also increased mitochondrial biogenesis in primary dopaminergic neurons and in the nigra of MPTP-intoxicated mice. However, RNS60 had no effect on lysosomal biogenesis. Interestingly, we found that RNS60 upregulated PGC1alpha and siRNA knockdown of PGC1alpha abrogated the ability of RNS60 to increase mitochondrial biogenesis. Furthermore, we delineated that RNS60 increased the transcription of Pgc1a via type IA phosphatidylinositol (PI) 3 kinase-mediated activation of cAMP-response element-binding protein (CREB). Accordingly, knockdown of the PI3K - CREB pathway suppressed RNS60-mediated mitochondrial biogenesis. These results describe a novel property of RNS60 of enhancing mitochondrial biogenesis via PI 3-kinase-CREB-mediated up-regulation of PGC1alpha, which may be of therapeutic benefit in different neurodegenerative disorders. PMID- 29188425 TI - Increased benefit of betrixaban among patients with a history of venous thromboembolism: a post-hoc analysis of the APEX trial. AB - : Hospitalized acute medically ill patients with a history of venous thromboembolism (VTE) are at increased risk for recurrent VTE. We characterized the efficacy and safety of betrixaban for prevention of recurrent VTE in these high risk patients. The APEX trial randomized 7513 acutely ill hospitalized medical patients at risk for developing VTE to receive either betrixaban for 35 42 days or enoxaparin for 10 +/- 4 days to prevent VTE. This exploratory post-hoc analysis assessed the efficacy and safety of betrixaban versus enoxaparin among subjects with and without prior VTE. Time-to-multiple symptomatic VTE events was also calculated. Approximately 8% of subjects in both arms had prior VTE, which was associated with a fourfold increase in adjusted risk of VTE [MV OR 4.03, 95% CI 3.06-5.30, p < 0.001]. Betrixaban reduced VTE compared with enoxaparin among subjects with prior VTE [32 (10.4%) vs. 55 (18.9%), RR 0.57, 95% CI 0.38-0.86, p = 0.006, ARR 8.5%, NNT 12] and without prior VTE [133 (3.9%) vs. 168 (4.9%), RR 0.79, 95% CI 0.64-0.99, p = 0.042, ARR 1.0%, NNT 100] (interaction p > 0.05). Additionally, four subjects in the enoxaparin arm and one subject in the betrixaban arm experienced a recurrent VTE. Compared with enoxaparin, betrixaban use was associated with reduction of recurrent VTE events through the active treatment period [36 vs. 57, HR 0.63, 95% CI 0.41-0.97, p = 0.045] and through the end of study [38 vs. 71, HR 0.54, 95% CI 0.36-0.81, p = 0.004]. Prior VTE is associated with a fourfold increase in the risk of VTE among hospitalized medically ill patients. Only 12 such patients would need to be treated with betrixaban versus enoxaparin to prevent an additional VTE endpoint. Betrixaban reduced not only the first but also all recurrent VTE events in a time-to-any event analysis. TRIAL REGISTRATION: http://www.clinicaltrials.gov , Unique identifier: NCT01583218. PMID- 29188426 TI - Investigating the contribution of task and response repetitions to the sequential modulations of attentional cueing effects. AB - We tested the nature of validity sequence effects. During visual search for targets, target-preceding peripheral cues at target position (valid condition) facilitate search relative to cues away from the target (invalid condition). This validity effect (i.e., advantage in valid compared to invalid conditions) is observed for cues that are not predictive of the target, and it reflects the cue's capture of attention. Importantly, the validity effect is stronger following valid than invalid trials. The underlying causes of this validity sequence effect are unknown. We, therefore, tested if the validity sequence effect reflected trial-to-trial priming or event-file coding. According to these explanations, full trial-to-trial repetitions and full changes of all stimulus features or of all stimulus and response features, respectively, would account for the validity sequence effect. However, the validity sequence effect could also reflect the participants' retention of a recently helpful cue (i.e., after a valid trial) and/or their suppression of a recently harmful cue (i.e., after an invalid trial). Here, to contrastively test these theories, from trial to trial, the tasks are repeated or switched. The results demonstrated that, under certain conditions, the validity sequence effect can survive task-switching (Experiments 1 and 2), which supports the retention/suppression account. When the tasks were strongly distinguished, however, the validity sequence effect did not survive task-switching (Experiment 3), which supports the event-coding account. Together, the results suggest that task structure can determine the impact of cue processing on subsequent trials, and the extent to which it reflects event-file coding.

AB - OBJECTIVES: Although strict blood glucose control during cardiovascular surgery is essential to avoid postoperative complications, the various changes in glucose levels that occur during surgery have not been investigated in detail. In this study, we continuously monitored blood glucose changes during aortic surgery using the STG-55R artificial endocrine pancreas (Nikkiso Inc., Tokyo). METHODS: Between December 2015 and 2016, we performed continuous blood glucose monitoring in 22 patients (14 men and 8 women, 72 +/- 11 years old), who required hypothermic circulatory arrest during an ascending/aortic arch surgery, at the Jichi Medical University Hospital. Ascending aorta replacements were performed in two patients and partial/total arch replacement, in 20. All the patients required selective cerebral perfusion and hypothermic circulatory arrest (bladder temperature at 25-26 degrees C) during distal anastomosis. Closed-loop continuous blood glucose monitoring was performed during cardiopulmonary bypass using the STG-55R artificial endocrine pancreas (Nikkiso Co., LTD, Tokyo). RESULTS: Blood glucose concentrations did not increase significantly from the time of the commencement of cardiopulmonary bypass to lower body ischemia. However, they dramatically increased immediately after reperfusion following lower body ischemia, and this hyperglycemia was sustained until the end of cardiopulmonary bypass. CONCLUSION: The current study clarified the peak glucose concentration during aortic surgery. These data may contribute to the management of blood glucose levels during aortic surgery.

AB - Chikungunya virus (CHIKV) is an arbovirus transmitted by Aedes mosquitos in tropical and subtropical regions across the world. After decades of sporadic outbreaks, it re-emerged in Africa, Asia, India Ocean and America suddenly, causing major regional epidemics recently and becoming a notable global health problem. Infection by CHIKV results in a spectrum of clinical diseases including an acute self-limiting febrile illness in most individuals, a chronic phase of recurrent join pain in a proportion of patients, and long-term arthralgia for months to years for the unfortunate few. No specific anti-viral drugs or licensed vaccines for CHIKV are available so far. A better understanding of virus-host interactions is essential for the development of therapeutics and vaccines. To this end, we reviewed the existing knowledge on CHIKV's epidemiology, clinical presentation, molecular virology, diagnostic approaches, host immune response, vaccine development, and available animal models.

AB - There is a vast body of literature supporting the use of stress myocardial perfusion imaging (MPI) in patients with known or suspected coronary artery disease. When applied in the appropriate clinical setting, MPI can aid, not only in diagnosis and risk stratification, but also in decision-making. In a case of a 58-year-old man with suspected coronary artery disease, we highlight how the appropriate use of stress MPI can leverage the diagnostic and prognostic utility of MPI in an effective, evidence-based decision-making aimed to achieve the best patient outcome. PMID- 29188434 TI - Photothrombotic Stroke as a Model of Ischemic Stroke. AB - The search of effective anti-stroke neuroprotectors requires various stroke models adequate for different aspects of the ischemic processes. The photothrombotic stroke model is particularly suitable for the study of cellular and molecular mechanisms underlying neurodegeneration, neuroprotection, and neuroregeneration. It is a model of occlusion of small cerebral vessels, which provides detailed study of molecular mechanisms of ischemic cell death and useful for search of potential anti-stroke agents. Its advantages include well-defined location and size of ischemic lesion that are determined by the aiming of the laser beam at the predetermined brain region; easy impact dosing by changing light intensity and duration; low invasiveness and minimal surgical intervention without craniotomy and mechanical manipulations with blood vessel, which carry the risk of brain trauma; low animal mortality and prolonged sensorimotor impairment that provide long-term study of stroke consequences including behavior impairment and recovery; independence on genetic variations of blood pressure and vascular architecture; and high reproducibility. This review describes the current application of the photothrombotic stroke model for the study of cellular and molecular mechanisms of stroke development and ischemic penumbra formation, as well as for the search of anti-stroke drugs. PMID- 29188435 TI - Antibody-Drug Conjugates: Pharmacokinetic/Pharmacodynamic Modeling, Preclinical Characterization, Clinical Studies, and Lessons Learned. AB - Antibody-drug conjugates are an emerging class of biopharmaceuticals changing the landscape of targeted chemotherapy. These conjugates combine the target specificity of monoclonal antibodies with the anti-cancer activity of small molecule therapeutics. Several antibody-drug conjugates have received approval for the treatment of various types of cancer including gemtuzumab ozogamicin (Mylotarg(r)), brentuximab vedotin (Adcetris(r)), trastuzumab emtansine (Kadcyla(r)), and inotuzumab ozogamicin, which recently received approval (Besponsa(r)). In addition to these approved therapies, there are many antibody drug conjugates in the drug development pipeline and in clinical trials, although these fall outside the scope of this article. Understanding the pharmacokinetics and pharmacodynamics of antibody-drug conjugates and the development of pharmacokinetic/pharmacodynamic models is indispensable, albeit challenging as there are many parameters to incorporate including the disposition of the intact antibody-drug conjugate complex, the antibody, and the drug agents following their dissociation in the body. In this review, we discuss how antibody-drug conjugates progressed over time, the challenges in their development, and how our understanding of their pharmacokinetics/pharmacodynamics led to greater strides towards successful targeted therapy programs. PMID- 29188436 TI - Epithelial separation theory for post-tonsillectomy secondary hemorrhage: evidence in a mouse model and potential heparin-binding epidermal growth factor like growth factor therapy. AB - OBJECTIVE: To provide histological evidence to investigate a theory for post tonsillectomy secondary hemorrhage (PTH) in a mouse model and to evaluate the potential for heparin-binding epidermal growth factor-like growth factor (HB-EGF) treatment on wound healing in this model. METHODS: A prospective randomized single-blinded cohort study. A uniform tongue wound was created in 84 mice (day 0). Mice were randomized to HB-EGF (treatment, n = 42) or saline (control, n = 42). In treatment mice, HB-EGF 5 ug/ml was administered intramuscularly into the wound daily (days 0-14). In control mice, normal saline was administered daily. Three mice from each group were sacrificed daily through day 14 and the wounds evaluated histologically by blinded reviewers. RESULTS: Key stages of wound healing, including keratinocyte proliferation and migration, wound contraction, epithelial separation, and neoangiogenesis, are defined with implications for post-tonsillectomy wound healing. Epithelial separation (59 vs. 100%, p = 0.003) and wound reopening (8 vs. 48%, p < 0.001) were reduced with HB-EGF. Epithelial thickness (220 vs. 30 um, p = 0.04) was greater with HB-EGF. Wound closure (days 4-5 vs. day 6, p = 0.01) occurred earlier with HB-EGF. CONCLUSIONS: In healing of oral keratinocytes on muscle epithelial separation secondary to muscle, contraction occurs concurrently with neoangiogenesis in the base of the wound, increasing the risk of hemorrhage. This potentially explains why post tonsillectomy secondary hemorrhage occurs and its timing. HB-EGF-treated wounds showed greater epithelial thickness, less frequent epithelial separation and wound reopening, and earlier wound closure prior to neovascularization, suggesting that HB-EGF may be a potential preventative therapy for PTH.

AB - PURPOSE: To identify primary sites of nasopharyngeal carcinoma (NPC) invasion on the staging head and neck magnetic resonance imaging (MRI) that correlate with distant metastases (DM). MATERIALS AND METHODS: Staging head and neck MRI examinations of 579 NPC patients were assessed for primary tumour invasion into 16 individual sites, primary stage (T) and nodal stage (N). Results were correlated with distant metastasis-free survival (DMFS) using the Cox regression, and the diagnostic performance of significant independent markers for DM was calculated. In addition, sites of primary tumour invasion were correlated also with involvement of the first echelon of ipsilateral nodes (FEN+) using logistic regression. RESULTS: Distant metastases were present in 128/579 NPC patients (22.1%) after intensity-modulated radiotherapy (IMRT)/chemo-IMRT and 5-year DMFS was 78.8%. Prevertebral space invasion (PVS+) and N stage, but not T stage, were independent prognostic markers of DMFS (p = 0.016, < 0.001, and 0.433, respectively). Compared to stage N3, PVS invasion had a higher sensitivity (28.1 vs. 68.8%), but lower specificity (90.5 vs. 47.4%) and accuracy (76.7 vs. 48.9%) for correlating patients with DM. PVS invasion, together with parapharyngeal fat space invasion (PPFS+), was also an independent predictive marker of FEN+. CONCLUSION: PVS was the only site of primary tumour invasion that independently correlated with DM, and together with PPFS + was an independent prognostic marker of FEN+, but the low specificity and accuracy of PVS invasion limits its use as a prognostic marker of DM. PMID- 29188440 TI - Minimizing irrigation water demand: An evaluation of shifting planting dates in Sri Lanka. AB - Climate change coupled with increasing demands for water necessitates an improved understanding of the water-food nexus at a scale local enough to inform farmer adaptations. Such assessments are particularly important for nations with significant small-scale farming and high spatial variability in climate, such as Sri Lanka. By comparing historical patterns of irrigation water requirements (IWRs) to rice planting records, we estimate that shifting rice planting dates to earlier in the season could yield water savings of up to 6%. Our findings demonstrate the potential of low-cost adaptation strategies to help meet crop production demands in water-scarce environments. This local-scale assessment of IWRs in Sri Lanka highlights the value of using historical data to inform agricultural management of water resources when high-skilled forecasts are not available. Given national policies prioritizing in-country production and farmers' sensitivities to water stress, decision-makers should consider local degrees of climate variability in institutional design of irrigation management structures. PMID- 29188438 TI - Mapping causal mutations by exome sequencing in a wheat TILLING population: a tall mutant case study. AB - Forward genetic screens of induced mutant plant populations are powerful tools to identify genes underlying phenotypes of interest. Using traditional techniques, mapping causative mutations from forward screens is a lengthy, multi-step process, requiring the identification of a broad genetic region followed by candidate gene sequencing to characterize the causal variant. Mapping by whole genome sequencing accelerates the identification of causal mutations by simultaneously defining a mapping region and providing information on the induced genetic variants. In wheat, although the availability of a high-quality draft genome assembly facilitates mapping and mutation calling, whole genome resequencing remains prohibitively expensive due to its large genome. In the current study, we used exome sequencing as a complexity reduction strategy to detect mutations associated with a target phenotype. In a segregating wheat EMS population, we identified a clear peak region on chromosome arm 4BS associated with increased plant height. Although none of the significant SNPs seemed causative for the mutant phenotype, they were sufficient to identify a linked ~ 1.9 Mb deletion encompassing nine genes. These genes included Rht-B1, which is known to have a strong effect on plant height and is a strong candidate for the observed phenotype. We performed simulation experiments to determine the impacts of sequencing depth and bulk size and discuss the importance of considering each factor when designing mapping-by-sequencing experiments in wheat. This approach can accelerate the identification of candidate causal point mutations or linked deletions underlying important phenotypes.

PMID- 29188441 TI - Vulnerability of Canadian aquatic ecosystems to nuclear accidents. AB - Several cesium and strontium bioaccumulation models are used widely in national and international guidance for ecological and human health risk assessments for radiocesium (134Cs and 137Cs) and radiostrontium (90Sr), but have not been used to make predictions of radiological risk from nuclear accidents under variable environmental conditions on broad geographical scales. In this paper, we first present models for predicting the bioaccumulation of cesium and strontium by aquatic biota based on ambient concentrations of dissolved potassium and calcium, respectively, and then test these models using independent data from aquatic ecosystems at Canadian nuclear sites. Secondly, models yielding the best predictions across a wide range of input parameters were selected to estimate bioaccumulation factors (BAFs) for cesium and strontium in aquatic ecosystems across Canada, using trophic level of organisms and dissolved potassium for cesium and calcium concentrations for strontium as predictor variables, and presented as contour maps of radiological risk. The models show that risk from bioaccumulation of cesium and strontium can vary by several orders of magnitude depending on site-specific environmental conditions and trophic ecology. Overall, our results suggest that single-parameter approaches taken by regulatory standards may either over- or under-predict radiological risk at many locations, and are thus not readily suitable to inform siting decisions for new nuclear developments. PMID- 29188442 TI - Categorizing coordination from the perception of joint actions. AB - The ability to perceive others' actions and coordinate our own body movements accordingly is essential for humans to interact with the social world. However, it is still unclear how the visual system achieves the remarkable feat of identifying temporally coordinated joint actions between individuals. Specifically, do humans rely on certain visual features of coordinated movements to facilitate the detection of meaningful interactivity? To address this question, participants viewed short video sequences of two actors performing different joint actions, such as handshakes, high fives, etc. Temporal misalignments were introduced to shift one actor's movements forward or backward in time relative to the partner actor. Participants rated the degree of interactivity for the temporally shifted joint actions. The impact of temporal offsets on human interactivity ratings varied for different types of joint actions. Based on human rating distributions, we used a probabilistic cluster model to infer latent categories, each revealing shared characteristics of coordinated movements among sets of joint actions. Further analysis on the clustered structure suggested that global motion synchrony, spatial proximity between actors, and highly salient moments of interpersonal coordination are critical features that impact judgments of interactivity. PMID- 29188443 TI - Cannibalism amongst penitentiary escapees from Sarah Island in nineteenth century Van Diemen's Land. AB - Alexander Pearce was an Irish convict incarcerated on Sarah Island on the west coast of Van Diemen's Land (modern day Tasmania, Australia) in 1822, following his transportation to the colony from the United Kingdom for seven years in 1819. On two occasions he escaped from the island, in September 1822 and again in November 1823, and was only able to survive the harsh conditions by killing and consuming his fellow escapees. Given that Pearce utilized the only sustenance that was at hand (i.e. his five companions), and that there was a temporal separation between the two episodes, this may represent a separate category of anthropophagy, that of serial opportunistic cannibalism.

PMID- 29188445 TI - Childhood physical maltreatment, perceived social isolation, and internalizing symptoms: a longitudinal, three-wave, population-based study. AB - A number of cross-sectional studies have consistently shown a correlation between childhood physical maltreatment, perceived social isolation and internalizing symptoms. Using a longitudinal, three-wave design, this study sought to assess the mediating role of perceived social isolation in adulthood in the association between childhood physical maltreatment and internalizing symptoms in adulthood. The study has a three-wave design. We used data collected from 1994 to 2008 within the framework of the Tromso Study (N = 4530), a representative prospective cohort study of men and women. Perceived social isolation was measured at a mean age of 54.7 years, and internalizing symptoms were measured at a mean age of 61.7 years. The difference-in-coefficients method was used to assess the indirect effects and the proportion (%) of mediated effects. Childhood physical maltreatment was associated with an up to 68% [relative risk (RR) = 1.68, 95% confidence interval (CI): 1.33-2.13] higher risk of perceived social isolation in adulthood. Childhood physical maltreatment and perceived social isolation in adulthood were associated with greater levels of internalizing symptoms in adulthood (p < 0.01). A dose-response association was observed between childhood physical maltreatment and internalizing symptoms in adulthood (p < 0.001). Perceived social isolation in adulthood mediated up to 14.89% (p < 0.05) of the association between childhood physical maltreatment and internalizing symptoms in adulthood. The results of this study indicate the need to take perceived social isolation into account when considering the impact of childhood physical maltreatment on internalizing symptoms. PMID- 29188446 TI - iCHRCloud: Web & Mobile based Child Health Imprints for Smart Healthcare. AB - Reducing child mortality with quality care is the prime-most concern of all nations. Thus in current IT era, our healthcare industry needs to focus on adapting information technology in healthcare services. Barring few preliminary attempts to digitalize basic hospital administrative and clinical functions, even today in India, child health and vaccination records are still maintained as paper-based records. Also, error in manually plotting the parameters in growth charts results in missed opportunities for early detection of growth disorders in children. To address these concerns, we present India's first hospital linked, affordable automated vaccination and real-time child's growth monitoring cloud based application- Integrated Child Health Record cloud (iCHRcloud). This application is based on HL7 protocol enabling integration with hospital's HIS/EMR system. It provides Java (Enterprise Service Bus and Hibernate) based web portal for doctors and mobile application for parents, enhancing doctor-parent engagement. It leverages highchart to automate chart preparation and provides access of data via Push Notification (GCM and APNS) to parents on iOS and Android mobile platforms. iCHRcloud has also been recognized as one of the best innovative solution in three nationwide challenges, 2016 in India. iCHRcloud offers a seamless, secure (256 bit HTTPS) and sustainable solution to reduce child mortality. Detail analysis on preliminary data of 16,490 child health records highlight the diversified need of various demographic regions. Thus, primary lesson would be to implement better validation strategies to fulfill the customize requisites of entire population. This paper presents first glimpse of data and power of the analytics in policy framework. PMID- 29188447 TI - Procrastination in the pigeon: Can conditioned reinforcement increase the likelihood of human procrastination? AB - Procrastination is the tendency to put off initiation or completion of a task. Although people are typically known to procrastinate, recent research suggests that they sometimes "pre-crastinate" by initiating a task sooner than they need to (Rosenbaum et al. in Psychological Science, 25(7), 1487-1496, 2014). A similar finding of precrastination was reported by Wasserman and Brzykcy (Psychonomic Bulletin & Review, 22, 1130-1134, 2015) with pigeons using a somewhat different procedure. In the present experiment, we used a procedure with pigeons that was more similar to the procedure used by Rosenbaum et al. Pigeons were given a choice between two sequences of events (concurrent chains). Choice of the procrastination chain resulted in color A, which 15-s later would change to color B and 5-s later resulted in reinforcement. Choice of the precrastination chain resulted in color C, which 5-s later would change to color D and 15-s later resulted in reinforcement. Thus, both chains led to reinforcement after 20 s. Results indicated that the pigeons procrastinated. That is, they preferred the 15 5 chain over the 5-15 chain. The results are consistent with Fantino's (Journal of the Experimental Analysis of Behavior, 12, 723-730, 1969) delay reduction theory, which posits that stimuli that signal a reduction in the delay to reinforcement, such as the 5-s stimulus that occurred immediately prior to reinforcement, serve as strong conditioned reinforcers and should be preferred. In support of this theory, the pigeons pecked most at the 5-s stimulus that led immediately to reinforcement, indicating that it had become a strong conditioned reinforcer. The results suggest that delay reduction theory, a theory that emphasizes the attraction to stimuli that predict reinforcement with a short delay, also may contribute to human procrastination behavior because when task completion comes just before the deadline, it may become a stronger conditioned reinforcer than if task completion comes earlier. PMID- 29188448 TI - Controlled information processing, automaticity, and the burden of proof. AB - Cognitive psychologists often distinguish between voluntary and involuntary/automatic processes in attention and cognitive control. Dedicated experimental paradigms have been developed to isolate involuntary information processing, but these paradigms tend to assume a rigid and inflexible process that is either stimulus-driven or built up through simple repetition. In contrast, voluntary information processing is often assumed when processing is in line with arbitrarily defined task-specific goals. Here I review evidence from multiple cases suggesting that ostensibly goal-directed cognitive processes may not be so voluntary and controlled. It is argued that automatic processes can be conditionalized to reflect the task relevance of the stimuli and selection history in a variety of ways, rapidly and flexibly adjusting in order to facilitate future goal-directed behavior. As a result, many studies assumed to have measured a voluntary cognitive process have likely measured an amalgam of voluntary and automatic processes, thus blurring the distinction between the two. Automaticity may be much broader and more sophisticated than has previously been thought, which has wide-reaching implications for our conception of human cognitive control. PMID- 29188450 TI - Ankle muscle activity modulation during single-leg stance differs between children, young adults and seniors. AB - PURPOSE: Incomplete maturation and aging-induced declines of the neuromuscular system affect postural control both in children and older adults and lead to high fall rates. Age-specific comparisons of the modulation of ankle muscle activation and behavioral center of pressure (COP) indices during upright stance have been rarely conducted. The objective of the present study was to quantify aging effects on a neuromuscular level. Thus, surface electromyography (SEMG) modulation and co-activity of ankle muscles during single-leg standing was compared in healthy children, young adults and seniors. METHODS: Postural steadiness (velocity and mean sway frequency of COP), relative muscle activation (SEMG modulation) and co-activation of two ankle muscles (tibialis anterior, TA; soleus, SO) were examined during single-leg stance in 19 children [age, 9.7 (SD 0.5) years], 30 adults [23.3 (1.5) years] and 29 seniors [62.7 (6.1) years]. RESULTS: Velocity of COP in medio-lateral and anterior-posterior directions, mean sway frequency in anterior-posterior direction, relative muscle activation (TA and SO) and co-activation revealed large age effects (P < 0.003, eta p2 > 0.14). Post-hoc comparisons indicated higher COP velocities, anterior-posterior frequencies, relative SO activation and co-activation in children and seniors when compared with adults. Relative TA activation was higher in children and adults compared with seniors (P < 0.001). CONCLUSIONS: Increased postural sway in children and seniors seems to be counteracted with higher TA/SO co-activity and SO modulation. However, TA modulation is higher in children and adults, whereas seniors' TA modulation capacity is diminished. An aging-induced decline of TA motor units might account for deteriorations of TA modulation in seniors. PMID- 29188449 TI - Current and New Therapeutic Strategies for Relapsed and Refractory Multiple Myeloma: An Update. AB - Although survival of multiple myeloma patients has at least doubled during recent years, most patients eventually relapse, and treatment at this stage may be particularly complex. At the time of relapse, the use of alternative drugs to those given upfront is current practice. However, many new options are currently available for the treatment of relapsed multiple myeloma, including recently approved drugs, such as the second- and third-generation proteasome inhibitors carfilzomib and ixazomib, the immunomodulatory agent pomalidomide, the monoclonal antibodies daratumumab and elotuzumab and the histone deacetylase inhibitor panobinostat, but also new targeted agents are under active investigation (e.g. signal transduction modulators, kinesin spindle protein inhibitors, and inhibitors of NF-kB, MAPK, AKT). We here describe a new paradigm for the treatment of relapsed multiple myeloma. The final goal should be finding a balance among efficacy, toxicity, and cost and, at the end of the road, achieving long-lasting control of the disease and eventually even cure in a subset of patients. PMID- 29188451 TI - Pediatric cleft palate patients show a 3- to 5-fold increase in cumulative radiation exposure from dental radiology compared with an age- and gender-matched population: a retrospective cohort study. AB - OBJECTIVE: The objective of the study was to compare estimates of pediatric cumulative exposure and lifetime attributable risk (LAR) of radiation-induced cancer from dental radiology between cleft palate (CP) subjects and age- and gender-matched controls (non-CP), with and without orthodontic treatment. MATERIALS AND METHODS: The radiation exposure frequency of CP subjects and non-CP controls with and without orthodontic treatment was compared for two-dimensional radiography (intra-oral, panoramic and cephalometric radiography), computed tomography (CT), and cone-beam CT (CBCT) using cumulative radiation dose as an estimate. From this dose estimate, the age- and gender-dependent risk for radiation-induced stochastic effects was calculated for each patient group. RESULTS: CP patients received more radiographic examinations than non-CP controls, with the exception of intra-oral radiographs. The cumulative dose to CP patients was considerably higher (1963 MUSv at the age of 20 years) than non-CP patients with (597 MUSv) and without (383 MUSv) orthodontic treatment, primarily due to the higher frequency of CT scanning. Accordingly, CP patients had a three to five times higher LAR than non-CP patients. CONCLUSIONS: This study suggests a significantly higher lifetime radiation exposure to CP patients than non-CP controls from dental radiographic procedures. Diagnostic benefits from the use of CT and CBCT in children must be justified and appropriate dose optimization strategies implemented. CLINICAL RELEVANCE: The present study indicates the need for proper justification and optimization of pediatric exposures in dentistry, with a special focus on high-risk groups. PMID- 29188452 TI - Bisphosphonates hinder osteoblastic/osteoclastic differentiation in the maxillary sinus mucosa-derived stem cells. AB - OBJECTIVES: Although bisphosphonates (BPs) are known to be associated with osteonecrosis of the maxilla, the precise effects of BPs on bone metabolism in human maxillary sinus mucosal cells (HMSMCs) are not yet known. The purposes of this study were to examine the effects of the BPs zoledronate (ZOL) and alendronate (ALN) on osteoblastic and osteoclastic differentiation in HMSMCs and to investigate the signaling pathways involved. MATERIALS AND METHODS: The effects of ZOL and ALN were assessed for osteoblast differentiation by alkaline phosphatase (ALP) activity, alizarin red staining, and RT-PCR for genes encoding Runx2 and osterix. Receptor activator of nuclear factor-kappaB ligand (RANKL) mediated osteoclast differentiation in bone marrow macrophages (BMMs) was also examined. RESULTS: ZOL and ALN both suppressed osteoblastic differentiation, as evidenced by their effects on ALP activity, mineralization nodule formation, and the mRNA expression levels of osteoblastic transcript factors. The RANKL/osteoprotegerin ratio in HMSMCs was increased by ALN, whereas ZOL had the opposite effect. Conditioned medium obtained from ALN-treated HMSMCs stimulated osteoclast formation and upregulated NFATc1 expression, whereas conditioned medium from ZOL-treated cells did not. ALN was more cytotoxic and stimulated apoptosis more strongly than ZOL. BPs decreased the protein levels of the non canonical Wnt signaling protein Wnt5a and calmodulin-dependent kinase II. Moreover, recombinant human Wnt5a reversed the effects of BPs on osteoblastic and osteoclastic differentiation. CONCLUSION: This study is the first demonstration that BPs exert negative effects on osteoblastic and osteoclastic processes via the non-canonical Wnt pathway in HMSMSCs. CLINICAL RELEVANCE: It suggests that patients taking BPs during the period of maxillary sinus lifting and amentation should be given special attention. PMID- 29188453 TI - Can the combination of laparoscopy and enhanced recovery improve long-term survival after elective colorectal cancer surgery? AB - AIM: Enhanced recovery after surgery (ERAS) programmes and laparoscopic techniques both provide short-term benefits to patients undergoing colorectal cancer surgery. ERAS protocol compliance may improve long-term survival in those undergoing open colorectal resection but as laparoscopic data has not been reported. Therefore, we aimed to investigate the impact of the combination of laparoscopy and ERAS management on 5-year overall survival. METHODS: A dedicated prospectively populated colorectal cancer surgery database was reviewed. Patient inclusion criteria were biopsy-proven colorectal adenocarcinoma, undergoing elective surgery undertaken with curative intent. All patients were managed within an established ERAS programme and routinely followed up for 5 years. Overall survival was measured using the log-rank Kaplan-Meier method at 5 years. RESULTS: Eight hundred fifty-four patients met the inclusion criteria. Four hundred eighty-one (56%) cases were laparoscopic with 98 patients (20%) requiring conversion. There were no differences in patient or tumour demographics between the surgical groups. Median ERAS protocol compliance was 93% (range 53-100%). Five-year overall survival was superior in laparoscopic cases compared with that of converted and open surgery (78 vs 68 vs 70%, respectively, p < 0.007). An open approach (HR 1.55, 95%CI 1.16-2.06, p = 0.002) and delayed hospital discharge (> 7 days, HR 1.5, 95%CI 1.13-1.9, p = 0.003) were the only modifiable risk factors associated with poor survival. CONCLUSIONS: The use of a laparoscopic approach with enhanced recovery after surgery management appears to have long-term survival benefits following colorectal cancer resection. PMID- 29188454 TI - A narrative review of the impact of interventions in acute kidney injury. AB - Acute kidney injury (AKI) is independently associated with significant morbidity and mortality, and is thus an important challenge facing physicians in modern healthcare. This narrative review assesses the impact of strategies employed to tackle AKI following the 2009 NCEPOD report on acute kidney injury (Sterwart et al. Acute kidney injury: adding insult to injury, pp 1-22, 2009). There is scarce and heterogeneous research into hard end points such as mortality and AKI progression for AKI interventions. This review found that e-alerts have varying effects on mortality and AKI progression, but decrease the incidence of contrast induced AKI. The use of AKI bundles delivers statistically significant improvements in mortality and AKI progression. Similarly, AKI nurses generate statistically significant improvements on hospital acquired AKI and mortality. As yet there is no evidence base for the effects of education, sick day rules and smart phone apps. Overall, a combination of e-alerts and AKI bundles supported by education yielded the most effective and statistically significant results. Current practice revolves around reactive rather than preventative behaviour. This narrative review discusses reactive interventions and their impact on the progression and severity of AKI, and on mortality from it. Preventative behaviour, such as risk stratification and early intervention in the deteriorating patient, may be influential in decreasing AKI incidence. PMID- 29188455 TI - The Role of Cardiologists in the Management of Patients with Heart Failure. AB - Heart failure is a complex clinical syndrome with a remarkable impact on health care systems in terms of patients' morbidity and mortality, as well as direct and indirect costs. It is essential to redesign models of care for patients with heart failure that are tailored on personalized health care needs and carried out in the most appropriate setting. There is some debate about the role of cardiologists in the management of patients with heart failure. Indeed, results regarding the inclination of cardiologists' patients to achieve better outcomes are controversial, given the heterogeneity of studies in terms of study design, population, setting and variables considered. The aim of this chapter is to describe and synthesize the current state of knowledge about the role of specialists in the management of patient with heart failure, and to assess whether there is a type of patients for which cardiologists demonstrate the greatest value or a setting of care where they add more benefit. PMID- 29188457 TI - Can the ability to adapt to exercise be considered a talent-and if so, can we test for it? AB - Talent identification (TI) is a popular and hugely important topic within sports performance, with an ever-increasing amount of resources dedicated to unveiling the next sporting star. However, at present, most TI processes appear to select high-performing individuals at the present point in time, as opposed to identifying those individuals with the greatest capacity to improve. This represents a potential inefficiency within the TI process, reducing its effectiveness. In this article, we discuss whether the ability to adapt favorably, and with a large magnitude, to physical training can be considered a talent, testing it against proposed criteria. We also discuss whether, if such an ability can be considered a talent, being able to test for it as part of the TI process would be advantageous. Given that such a capacity is partially heritable, driven by genetic variation between individuals that mediate the adaptive response, we also explore whether the information gained from genetic profiling can be used to identify those with the greatest capacity to improve. Although there are some ethical hurdles which must be considered, the use of genetic information to identify those individuals with the greatest capacity appears to hold promise and may improve both the efficiency and effectiveness of contemporary TI programmes. PMID- 29188456 TI - Prophylactic effect of neoadjuvant chemotherapy in gastric cancer patients with postoperative complications. AB - BACKGROUND: The occurrence of postoperative complications may have a significant negative impact on the prognosis of patients with gastrointestinal cancers. The inflammatory response releases systemic cytokines, which may induce residual cancer cell growth. Recently, neoadjuvant chemotherapy (NAC) was found to improve the prognosis of advanced gastric cancer (GC). We hypothesize that when postoperative complications occur after gastrectomy, NAC treatment of micrometastases can prevent residual cancer cell growth. METHODS: This study included 101 patients who underwent curative resection after NAC for GC from 2005 to 2015. Clinical data, including intraoperative parameters, were collected retrospectively. Overall survival (OS) and relapse-free survival (RFS) were compared between the patients with complications and those without complications. RESULTS: Of the 101 patients, 35 (34.7%) had grade 2 or higher complications. Among those with complications, the 3- and 5-year OS rates were 63.5 and 58.2% and the 3- and 5-year RFS rates 41.7 and 41.7%, respectively. Among those without complications, the 3- and 5-year OS rates were 65.9 and 56.3% and the 3- and 5 year RFS rates 51.1 and 43.9%, respectively. There was no significant difference in prognosis between the patients with complications and those without complications. CONCLUSION: Our study is the first to demonstrate the potential of NAC to abolish the poor prognosis induced by postoperative complications after curative resection for GC.

In this paper, I contrast microbiology's current diversity ideal with its influential predecessor in the twentieth century, that of purity, as epitomized in Robert Koch's bacteriological culture methods. Purity and diversity, the two polar opposites with regard to making sense of the microbial world, have been operationalized in microbiological practice by tools such as the "clean" Petri dish versus the "dirty" Winogradsky column, the latter a container that mimics, in the laboratory, the natural environment that teems with diverse microbial life. By tracing the impact of the practices and concepts of purity and diversity on microbial classification through a history of techniques, tools, and manuals, I show the shifts in these concepts over the last century. Juxtaposing the dominant purity ideal with the more restricted, but continuously articulated, diversity ideal in microbial ecology not only provides a fresh perspective on microbial classification that goes beyond its intellectual history, but also contextualizes the present focus on diversity. By covering the period of a century, this paper outlines a revised longue duree historiography that takes its inspiration from artifacts, such as Petri dish and the Winogradsky column, and thereby simple, but influential technologies that often remain invisible. This enables the problem of historical continuity in modern science to be addressed and the accelerationist narratives of its development to be countered.

AB - El Nino, an interannual climate event characterized by elevated oceanic temperature, is a prime threat for coral reef ecosystems worldwide, owing to their thermal threshold sensitivity. Phytoplankton plays a crucial role in the sustenance of reef trophodynamics. The cell size of the phytoplankton forms the "master morphological trait" with implications for growth, resource acquisition, and adaptability to nutrients. In the context of a strong El Nino prediction for 2015-2016, the present study was undertaken to evaluate the variations in the size-structured phytoplankton of Kavaratti reef waters, a major coral atoll along the southeast coast of India. The present study witnessed a remarkable change in the physicochemical environment of the reef water and massive coral bleaching with the progression of El Nino 2015-2016 from its peak to waning phase. The fluctuations observed in sea surface temperature, pH, and nutrient concentration of the reef water with the El Nino progression resulted in a remarkable shift in phytoplankton size structure, abundance, and community composition of the reef waters. Though low nutrient concentration of the waning phase resulted in lower phytoplankton biomass and abundance, the diazotroph Trichodesmium erythraeum predominated the reef waters, owing to its capability of the atmospheric nitrogen fixation and dissolved organic phosphate utilization. PMID- 29188463 TI - Evaluation of anterior chamber parameters with spectral-domain optical coherence tomography. AB - PURPOSE: To evaluate several anterior chamber parameters in healthy young adults using spectral-domain optical coherence tomography and to describe the repeatability and reproducibility of this method. STUDY DESIGN: Prospective clinical study. METHODS: Fifty-two eyes of 52 healthy volunteers were enrolled. Manual measurements of the anterior chamber angle (ACA500 and ACA750), angle opening distance (AOD500 and AOD750), angle-to-angle distance (ATA), anterior chamber width (ACW), and lens vault (LV) were obtained. RESULTS: The mean nasal ACA500 was 44.87 +/- 12.92 degrees ; ACA750, 43.94 +/- 10.41 degrees ; AOD500, 672.54 +/- 270.19 um; AOD750, 881.87 +/- 290.55 um. The mean temporal ACA500 was 41.46 +/- 11.20 degrees ; ACA750, 41.27 +/- 11.31 degrees ; AOD500, 603.15 +/- 232.28 um; AOD750, 823.46 +/- 308.76 um. The differences between the corresponding nasal and temporal parameters were statistically significant. The ACW was 11.97 +/- 0.42 mm, the ATA was 12.10 +/- 0.43 mm, and the LV was 3.71 +/- 232.93 um. The ACA was highly associated with the LV. The intraclass correlation coefficients ranged from 0.984 to 0.999 for the intraobserver repeatability and from 0.966 to 0.998 for the interobserver reproducibility. CONCLUSIONS: This study assessed anterior chamber parameters in healthy young adults using spectral domain optical coherence tomography. This technique reveals the spatial relationships of the ocular structures, provides high-resolution images, and results in high degrees of intraobserver and interobserver repeatabilities. PMID- 29188462 TI - Quantification of retinal changes after resolution of submacular hemorrhage secondary to polypoidal choroidal vasculopathy. AB - PURPOSE: To evaluate changes in the thickness of retinal layers after resolution of submacular hemorrhage secondary to polypoidal choroidal vasculopathy (PCV). STUDY DESIGN: Retrospective, observational study. METHODS: This study included 21 patients (21 eyes) who had been diagnosed with submacular hemorrhage secondary to PCV and treated using anti-vascular endothelial growth factor monotherapy. After the hemorrhage had resolved, the thicknesses of the retinal layers were measured on horizontal- and vertical-crosshair optical coherence tomography scan images. The thickness of each layer in the region affected by the hemorrhage was compared with the thickness of the layer in the corresponding region in the fellow eye, as well as between an unaffected region in the eye with the hemorrhage and the corresponding region in the fellow eye. RESULTS: Optical coherence tomography (OCT) was performed 5.5+/-2.8 months after diagnosis. In the horizontal OCT images, the outer plexiform layer (OPL) and outer nuclear layer (ONL) + photoreceptor layer (PRL) were significantly thinner in the affected region than in the corresponding region (P = 0.019 and P <0.001, respectively). In the vertical OCT image, the ONL+PRL was significantly thinner in the affected region than in the corresponding region (P <0.001). The thickness of the retinal layer in the unaffected region did not differ from that in the corresponding region of the fellow eye. CONCLUSIONS: The significant thinning of the outer retinal layers in the regions affected by submacular hemorrhage suggests that the hemorrhage induces marked damage in the outer retinal layers, explaining the poor visual prognosis of submacular hemorrhage. PMID- 29188464 TI - A Statewide Hospital-Based Safe Infant Sleep Initiative: Measurement of Parental Knowledge and Behavior. AB - Sleep-related infant deaths are a leading cause of infant mortality in Georgia, and these deaths are largely associated with unsafe sleep practices among caregivers. In early 2016, the Georgia Department of Public Health launched the Georgia Safe to Sleep Hospital Initiative, providing hospitals with safe infant sleep information and educational materials to be distributed to families and newborns. This study examined the knowledge and behaviors of a sample of Georgia parents after the implementation of the Hospital Initiative and identified the family characteristics and intervention components most closely associated with the knowledge and practice of safe infant sleep. The primary caretakers of all infants born in Georgia from August to October 2016 were invited to complete a web-based survey 1 month after hospital discharge. The final sample size included 420 parents of newborns, and the primary outcomes assessed included two measures of knowledge and four measures of infant sleep behaviors regarding infant sleep position and location. Most respondents demonstrated knowledge of the correct recommended sleep position (90%) and location (85%). Logistic regression revealed that receipt of information in the hospital was significantly correlated with safe sleep behaviors, and infant sleep habits tended to influence safe sleep practices. Additionally, Medicaid parents receiving bassinets from the hospital were 74% less likely to bed share (OR 0.26; 95% CI 0.007). Implementation of a statewide hospital initiative was associated with high levels of parental knowledge and behavior and may have been successful in reducing the practice of bed sharing among Medicaid parents. PMID- 29188465 TI - Demographic and Travel Characteristics of Travel-Associated Zika Virus Infection Case-Patients in San Diego County, California (January 1, 2016-March 31, 2017). AB - Most Zika disease cases diagnosed in the continental US have been associated with travel to areas with risk of Zika transmission, mainly the Caribbean and Latin America. Limited information has been published about the demographic and travel characteristics of Zika case-patients in the United States, besides their age and gender. During 2016-2017 the County of San Diego Health and Human Services Agency, California, expanded the scope and completeness of demographic and travel information collected from Zika case-patients for public health surveillance purposes. The majority (53.8%) of travel-related Zika virus infection case patients (n = 78) in the county were Hispanic, significantly higher (p <= 0.05) than the 33.0% of Hispanics in the county. Foreign-born residents, mainly from Mexico, were also overrepresented among cases compared to their share in the county population (33.3 vs. 23.0%; p <= 0.05). Seventeen (21.8%) patients reported a primary language other than English (14 Spanish). Most case-patients traveled for tourism (54%) or to visit friends and relatives (36%). This surveillance information helps identify higher-risk populations and implement culturally targeted interventions for Zika prevention and control. PMID- 29188466 TI - Neuronal avalanches: Where temporal complexity and criticality meet. AB - The model of the current paper is an extension of a previous publication, wherein we have used the leaky integrate-and-fire model on a regular lattice with periodic boundary conditions, and introduced the temporal complexity as a genuine signature of criticality. In that work, the power-law distribution of neural avalanches was a manifestation of supercriticality rather than criticality. Here, however, we show that the continuous solution of the model and replacing the stochastic noise with a Gaussian zero-mean noise leads to the coincidence of power-law display of temporal complexity, and spatiotemporal patterns of neural avalanches at the critical point. We conclude that the source of inconsistency may be a numerical artifact originated by the discrete description of the model which may imply a slow numerical convergence of the avalanche distribution compared to temporal complexity. PMID- 29188467 TI - Diagnosing tick-borne encephalitis: a re-evaluation of notified cases. AB - We set out to investigate the serological response of TBE virus (TBEV)-specific IgM and IgG antibodies in stored serum and cerebrospinal fluid (CSF) in notified TBE patients, in order to confirm or reject the diagnosis. We applied the ELISA methods used in clinical practice, Enzygnost and Immunozym, and assessed RT-PCR as a diagnostic tool. A total of 173 TBE cases were notified to the Public Health Agency. Samples from 129 patients were eligible for the study. Stored serum samples were found for 111 patients and CSF samples for 88 patients. All serum samples were analyzed with both Enzygnost and Immunozym, as well as an additional 140 control samples. CSF samples, including samples from ten controls, were analyzed with Immunozym. RT-PCR for TBEV was performed on 126 serum, two whole blood, 96 CSF, two feces and four nasopharynx samples. Only two of 111 notified patients lacked detectable TBEV IgM in serum, from whom one sample was RT-PCR positive. According to the ECDC definition, 117/129 (90.7%) of the reported TBE cases were confirmed. Positive RT-PCR results were obtained in eight patients, one from whole blood and eight from serum samples. Four out of eight of the RT PCR positive patients were TBEV-IgM positive and none had detectable TBEV specific IgG. All of the tested CSF, feces and nasopharynx samples were RT-PCR negative. TBEV-specific IgG was detected in 88.4% and IgM in 31.6% of the CSF samples. RT-PCR on serum samples and CSF IgG antibodies can be used as complementary methods in TBE diagnostics, not least early in the disease course. PMID- 29188468 TI - The role of perceived threat during emergency department cardiac evaluation and the age-posttraumatic stress disorder link. AB - Evaluation for acute coronary syndrome (ACS) can trigger posttraumatic stress symptoms (PSS). Research suggests that younger, versus older, individuals may be at elevated risk for PSS after ACS evaluation. It has been proposed that younger individuals may be at greater risk because they perceive the suspected ACS event as more threatening than their older counterparts; however, this has yet to be tested. We examined whether perceived threat during ACS evaluation mediated the association between age and PSS after ACS evaluation in an observational cohort study of patients presenting to the emergency department (ED) with suspected ACS. Demographics and perceived threat were assessed in the ED. PSS were measured upon inpatient transfer or by phone 3 days later. The analytic sample comprised 871 adult participants. Multiple linear regression was used to examine (1) associations of age and perceived threat with PSS and (2) whether perceived threat mediated the association. Bootstrapping with percentile-based confidence intervals (CIs) was used to test the indirect effect. Each year of age was associated with lower PSS (b = - 0.12, p < .001), independent of covariates. Older age was associated with lower perceived threat during ACS evaluation (b = - 0.05, p < .001). Greater threat perceptions predicted greater PSS (b = 0.94, p < .0001). The indirect effect (- 0.04) was statistically significant (95% CI - 0.07, - 0.02). Younger, versus older, individuals are at risk for greater PSS after ACS evaluation, and elevated perceived threat partially mediated this association. Understanding age differences in PSS development risk and the potential impact of age on threat perceptions may help inform ED treatment. PMID- 29188469 TI - MET-targeting antibody (emibetuzumab) and kinase inhibitor (merestinib) as single agent or in combination in a cancer model bearing MET exon 14 skipping. AB - Purpose Approximately 3% of lung cancer bears mutations leading to MET exon 14 skipping, an oncogenic driver which is further evidenced by case reports of patient response to MET kinase inhibitor treatment. Approximately 15% of tumors harboring MET exon14 skipping have concurrent MET amplification. Experimental Design Merestinib is a type II MET kinase inhibitor. Emibetuzumab, a bivalent anti-MET antibody, internalizes MET receptor. Each single agent and the combination were evaluated in the Hs746t gastric cancer line bearing MET exon14 skipping and MET amplification. Results Merestinib inhibited Hs746t cell proliferation (IC50=34 nM) and totally eliminated pMET at 100nM. Emibetuzumab showed little anti-proliferative activity against Hs746t cells (IC50>100nM), did not reduce pMET, and slightly reduced cell surface MET. In the Hs746t xenograft model, dose dependent differences in durability of response were seen with merestinib including durable tumor regression (91.8%) at 12 mg/kg qd. Emibetuzumab treatment (10mg/kg qw) provided transient tumor regression (37.7%), but tumors re-grew while on treatment. Concurrent combination of merestinib (6 mg/kg qd) and emibetuzumab resulted in 85% tumor regression, while a sequential combination (initiating merestinib first) resulted in longer duration of treatment response. Conclusions Data in this study support a clinical evaluation of merestinib in patients with MET exon 14 skipping (NCT02920996). As a type II MET kinase inhibitor, merestinib may provide a therapeutic option to treatment naive patients or to patients who progress on type I MET inhibitor treatment. Data also support clinical evaluation of the sequential combination of merestinib with emibetuzumab when patients progress on single agent merestinib. PMID- 29188470 TI - Femtosecond laser-assisted cataract surgery with bimanual technique: learning curve for an experienced cataract surgeon. AB - PURPOSE: To describe the intraoperative complications and the learning curve of microincision cataract surgery assisted by femtosecond laser (FLACS) with bimanual technique performed by an experienced surgeon. METHODS: It is a prospective, observational, comparative case series. A total of 120 eyes which underwent bimanual FLACS by the same experienced surgeon during his first experience were included in the study; we considered the first 60 cases as Group A and the second 60 cases as Group B. In both groups, only nuclear sclerosis of grade 2 or 3 was included; an intraocular lens was implanted through a 1.4-mm incision. Best-corrected visual acuity (BCVA), surgically induced astigmatism (SIA), central corneal thickness and endothelial cell loss (ECL) were evaluated before and at 1 and 3 months after surgery. Intraoperative parameters, and intra- and post-operative complications were recorded. RESULTS: In Group A, we had femtosecond laser-related minor complications in 11 cases (18.3%) and post operative complications in 2 cases (3.3%); in Group B, we recorded 2 cases (3.3%) of femtosecond laser-related minor complications with no post-operative complications. Mean effective phaco time (EPT) was 5.32 +/- 3.68 s in Group A and 4.34 +/- 2.39 s in Group B with a significant difference (p = 0.046). We recorded a significant mean BCVA improvement at 3 months in both groups (p < 0.05) and no significant SIA nor corneal pachymetry changes in the two groups during the follow-up (p > 0.05). Finally, we found significant ECL in both groups with a significant difference between the two groups (p = 0.042). CONCLUSIONS: FLACS with bimanual technique and low-energy LDV Z8 is associated with a necessary initial learning curve. After the first adjustments in the surgical technique, this technology seems to be safe and effective with rapid visual recovery and it helps surgeons to standardize the crucial steps of cataract surgery. PMID- 29188471 TI - Comparison of trypan blue and Brilliant Blue G for staining of the anterior lens capsule during cataract surgery: short-term results. AB - PURPOSE: The present study aimed to evaluate the potential corneal endothelial cell toxicity of trypan blue (TB) and Brilliant Blue G (BBG), two dyes used to stain the anterior capsule in cataract surgery. METHODS: We conducted a single center, prospective, randomized study in which 150 eyes of 117 patients were randomly divided into control (CT), TB, and BBG groups. Preoperative and postoperative (1, 3, and 6 months) values for corrected distance visual acuity (CDVA), corneal endothelial cell count, and central corneal thickness were compared among the three groups. RESULTS: A total of 111 eyes from 88 patients were completely analyzed. The CDVA (logarithm of the minimal angle of resolution) values in the CT, TB, and BBG groups 1 month after surgery were 0.001, 0.023, and 0.019, respectively. The corneal endothelial cell counts 6 months after surgery were 2711 +/- 225, 2748 +/- 251, and 2680 +/- 284 cells/mm2, respectively. The central corneal thicknesses 6 months after surgery were 524.3 +/- 35.5, 532.2 +/- 36.1, and 531.4 +/- 33.0 um, respectively. There were no significant differences in CDVA, endothelial cell count, or central corneal thickness among the three groups during the follow-up period. CONCLUSIONS: Our findings indicate that neither TB nor BBG was associated with detectable toxicity to corneal endothelial cells during cataract surgery, even when injected directly into the anterior chamber. Additionally, BBG exhibited equivalent staining efficiency to TB. PMID- 29188472 TI - Small Intestinal Bacterial Overgrowth: Should Screening Be Included in the Pre fecal Microbiota Transplantation Evaluation? AB - BACKGROUND: Fecal microbiota transplantation (FMT) is safe and effective for recurrent Clostridium difficile infection (rCDI) and often involves terminal ileal (TI) stool infusion. Patients report gastrointestinal (GI) symptoms post FMT despite rCDI resolution. Small intestinal bacterial overgrowth (SIBO) screening is not routinely performed pre-FMT. The effect of donor/recipient SIBO status on FMT outcomes and post-FMT GI symptoms is unclear. We aim to evaluate the value of pre-FMT SIBO screening on post-FMT outcomes and symptoms. METHODS: This was a prospective pilot study of consecutive adults with rCDI undergoing FMT by colonoscopy at a tertiary center. Routine pre-FMT screening and baseline lactulose breath tests (LBTs) were performed for donors and recipients. Positive LBT required a rise > 20 ppm in breath hydrogen or any methane level > 10 ppm within 90 min. The presence of GI symptoms and CDI resolution were assessed 8 weeks post-FMT. Fisher's exact/Student's t tests were performed for statistical analyses. RESULTS: Twenty recipients (58.3 years, 85% women) enrolled in the study. Fourteen (70%) FMTs involved TI stool infusion. Four (20%) recipients and six (30%) donors had positive LBT pre-FMT. At 8 weeks post-FMT, 17 (85%) recipients had CDI resolution and five (25%) reported GI symptoms. Pre-FMT LBT result was not associated with post-FMT CDI resolution or GI symptoms. There was a trend toward increased GI symptoms among recipients receiving stool from LBT positive donors (50 vs 14.2%, p = 0.09). CONCLUSIONS: FMT is effective and well tolerated for rCDI. Positive LBT in asymptomatic donors may have an effect on post-FMT GI symptoms. Larger studies are needed. PMID- 29188473 TI - Effect of simvastatin on sensorial, motor, and morphological parameters in sciatic nerve crush induced-neuropathic pain in rats. AB - The present study compares the effects of a low and high doses of simvastatin in a model of peripheral neuropathy by evaluating sensorial, motor, and morphological parameters. First, male Wistar rats were orally treated with vehicle (saline, 1 mL/kg), simvastatin (2 and 80 mg/kg) or morphine (2 mg/kg, s.c.), 1 h before 2.5% formalin injection. Neuropathic pain was induced by crushing the sciatic nerve, and mechanical and cold allodynia, nerve function, histology, MPO and NAG concentrations, as well as mevalonate induced-nociception were evaluated. Animals were orally treated with vehicle, simvastatin, or gabapentin (30 mg/kg) for 18 days. Simvastatin (2 and 80 mg/kg) reduced the inflammatory pain induced by formalin, but failed to decrease the paw edema. Mechanical allodynia was reduced by the simvastatin (2 mg/kg) until the 12th day after injury and until the 18th day by gabapentin. However, both simvastatin and gabapentin treatments failed in attenuated cold allodynia or improved motor function. Interestingly, both doses of simvastatin showed a neuroprotective effect and inhibited MPO activity without altering kidney and hepatic parameters. Additionally, only the higher dose of simvastatin reduced the cholesterol levels and the nociception induced by mevalonate. Our results reinforce the antinociceptive, antiallodynic, and anti-inflammatory effects of oral simvastatin administration, which can strongly contribute to the sciatic nerve morphology preservation. Furthermore, our data suggest that lower and higher doses of simvastatin present beneficial effects that are dependent and independent of the mevalonate pathway, respectively, without causing signs of nerve damage. PMID- 29188474 TI - Temporal Anaphora with Spanish Imperfecto. AB - This paper argues against the assumption that Spanish-and more generally Romance imperfective past (IMP) is an intrinsically anaphoric tense. It is a widely accepted view that IMP requires a temporal discourse antecedent to be licensed. My aim is to show that such requirement is not actually in force when IMP combines with a stative/atelic predicate. In fact, with stative/atelic predicates, IMP (a) is acceptable in isolated sentences with no suitable antecedent available, (b) is able to access implicit assumptions that are not available with telic predicates-but do not behave as real antecedents, and (c) does not trigger certain perspectivisation effects that depend on the existence of a temporal antecedent. As a result, an asymmetry arises between continuous and habitual interpretations of IMP, which do not require retrieving a temporal antecedent, and progressive and narrative interpretations, which do need an accessible antecedent. Thus, the relevance of a discourse antecedent varies according to the lexical aspect of the predicate and the corresponding interpretations, and the alleged anaphoric nature of IMP cannot be a feature of its semantics: it is rather pragmatically derived from imperfectivity. PMID- 29188476 TI - Interpersonal Needs, Depressive Symptoms, and Suicide Ideation in a Sample of Portuguese Elderly Patients Recovering from Acute Medical Conditions. AB - The aim of the present study was to test whether perceived burdensomeness and thwarted belongingness are related to suicide ideation, when controlling for depressive symptoms. The sample consisted of elderly patients recovering from acute medical conditions who were recruited in a medical recovery clinic. Results demonstrated that depressive symptoms and thwarted belongingness related to the suicide ideation item of the Beck Depression Inventory-II, used as an indicator of suicide ideation. Depressive symptoms and thwarted belongingness also discriminated between participants with suicide ideation and participants without suicide ideation as defined by suicide items of the Symptom-Driven Diagnostic System for Primary Care. Results are discussed in terms of potential cultural influences, and clinical implications are highlighted. PMID- 29188478 TI - [Comprehensive geriatric care for frail elderly at home: a feasibility study]. AB - OBJECTIVE: To evaluate the feasibility of a study on the content and effect of comprehensive geriatric care (CGC) at home for frail elderly. METHOD: Case managers invited new CGC patients of one care organization for participation in the study. At two moments, questionnaires were conducted on (social) functioning, quality of life, perceived problems, perceived informal caregiver burden, and self-management. Information on received care was collected from the patients' medical records, In addition, a questionnaire was administered to the referring physician. Feasibility was evaluated descriptively on three domains; inclusion, follow up, and data collection. RESULTS: The intended number of 25 participants was not reached, mostly because clients did not comply with inclusion criteria, and because case managers felt uncomfortable asking patients for participation in the study. Of the 14 participants, 12 were followed until the follow-up measurement. Several questionnaire domains appeared difficult to answer for participants. It also appeared difficult to collect information on received care from the medical records. Questionnaire response among general practitioners was 6 out of 11. CONCLUSION: Due to the vulnerability of the targeted group and logistical challenges, the inclusion of participants for the study was more difficult than originally thought. In combination with the difficulties in data collection, this suggests that a large-scale study on the content and effect of CGC is not feasible. Qualitative research methodologies, preferably combined with quantitative methods, offer better opportunities to understand the value of CGC for frail elderly living at home. PMID- 29188477 TI - CRISPR/Cas9-mediated efficient editing in phytoene desaturase (PDS) demonstrates precise manipulation in banana cv. Rasthali genome. AB - The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR associated protein 9 (Cas9) has been reported for precise genome modification in many plants. In the current study, we demonstrate a successful mutation in phytoene desaturase (RAS-PDS) of banana cv. Rasthali using the CRISPR/Cas9 system. Two PDS genes were isolated from Rasthali (RAS-PDS1 and RAS-PDS2), and their protein sequence analysis confirmed that both PDS comprises conserved motifs for enzyme activity. Phylogenetic analysis of RAS-PDS1 and RAS-PDS2 revealed a close evolutionary relationship with other monocot species. The tissue specific expression profile of RAS-PDS1 and RAS-PDS2 in Rasthali suggested differential regulation of the genes. A single 19-bp guide RNA (gRNA) was designed to target the conserved region of these two RAS-PDS and transformed with Cas9 in embryogenic cell suspension (ECS) cultures of cv. Rasthali. Complete albino and variegated phenotype were observed among regenerated plantlets. DNA sequencing of 13 plants confirmed the indels with 59% mutation frequency in RAS PDS, suggesting activation of the non-homologous end-joining (NHEJ) pathway. The majority of mutations were either insertion (1-5) or deletion (1-4) of nucleotides near to protospacer adjacent motif (PAM). These mutations have created stop codons in RAS-PDS sequences which suggest premature termination of RAS-PDS protein synthesis. The decreased chlorophyll and total carotenoid contents were detected in mutant lines that revealed the functional disruption of both RAS-PDS genes. Our results demonstrate that genome editing through CRISPR/Cas9 can be applied as an efficient tool for banana genome modification. PMID- 29188475 TI - Current Perspectives on Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis. AB - Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are considered a delayed-type hypersensitivity reaction to drugs. They represent true medical emergencies and an early recognition and appropriate management is decisive for the survival. SJS/TEN manifest with an "influenza-like" prodromal phase (malaise, fever), followed by painful cutaneous and mucous membrane (ocular, oral, and genital) lesions, and other systemic symptoms. The difference between SJS, SJS/TEN overlap, and TEN is defined by the degree of skin detachment: SJS is defined as skin involvement of < 10%, TEN is defined as skin involvement of > 30%, and SJS/TEN overlap as 10-30% skin involvement. The diagnosis of different degrees of epidermal necrolysis is based on the clinical assessment in conjunction with the corresponding histopathology. The mortality rates for SJS and TEN have decreased in the last decades. Today, the severity-of illness score for toxic epidermal necrolysis (SCORTEN) is available for SJS/TEN severity assessment. Drugs with a high risk of causing SJS/TEN are anti-infective sulfonamides, anti-epileptic drugs, non-steroidal anti-inflammatory drugs of the oxicam type, allopurinol, nevirapine, and chlormezanone. Besides conventional drugs, herbal remedies and new biologicals should be considered as causative agents. The increased risk of hypersensitivity reactions to certain drugs may be linked to specific HLA antigens. Our understanding of the pathogenesis of SJS/TEN has improved: drug-specific T cell-mediated cytotoxicity, genetic linkage with HLA- and non-HLA-genes, TCR restriction, and cytotoxicity mechanisms were clarified. However, many factors contributing to epidermal necrolysis still have to be identified, especially in virus-induced and autoimmune forms of epidermal necrolysis not related to drugs. In SJS/TEN, the most common complications are ocular, cutaneous, or renal. Nasopharyngeal, esophageal, and genital mucosal involvement with blisters, erosions as well as secondary development of strictures also play a role. However, in the acute phase, septicemia is a leading cause of morbidity and fatality. Pulmonary and hepatic involvement is frequent. The acute management of SJS/TEN requires a multidisciplinary approach. Immediate withdrawal of potentially causative drugs is mandatory. Prompt referral to an appropriate medical center for specific supportive treatment is of utmost importance. The most frequently used treatments for SJS/TEN are systemic corticosteroids, immunoglobulins, and cyclosporine A. PMID- 29188479 TI - Racial disparity in breast cancer: can it be mattered for prognosis and therapy. AB - Breast cancer (BC) has emerged as a deadly disease that affects the lives of millions of women worldwide. It is the second leading cause of cancer-related deaths in the United States. Advancements in BC screening, preventive measures and treatment have resulted in significant decline in BC related deaths. However, unacceptable levels of racial disparity have been consistently reported, especially in African-American (AA) women compared to European American (EA). AA women go through worse prognosis, shorter survival time and higher mortality rates, despite higher cancer incidence reported in EA. These disparities are independent of socioeconomic status, access to healthcare or age, or even the stage of BC. Recent race-specific genetic and epigenetic studies have reported biological causes, which form the crux of this review. However, the developments are just the tip of the iceberg. Prioritizing primary research towards studying race-specific tumor microenvironment and biological composition of the host system in delineating the cause of these disparities is utmost necessary to ameliorate the disparity and design appropriate diagnosis/treatment regimen for AA women suffering from BC. In this review article, we discuss emerging trends and exciting discoveries that reveal how genetic/epigenetic circuitry contributed to racial disparity and discussed the strategies that may help in future therapeutic development. PMID- 29188480 TI - A function-blocking CD47 antibody modulates extracellular vesicle-mediated intercellular signaling between breast carcinoma cells and endothelial cells. AB - Tumor cells release extracellular vesicles (EVs) into the tumor microenvironment that may facilitate malignant progression and metastasis. Breast carcinoma EVs express high levels of the thrombospondin-1 and signal regulatory protein-alpha receptor CD47, which is the target of several experimental therapeutics currently in clinical trials. We analyzed changes in gene expression and function in human umbilical vein endothelial cells (HUVEC) induced by treatment with EVs derived from breast carcinoma cells and the effects of the function-blocking CD47 antibody B6H12 on the resulting intercellular communication. CD47+ EVs exhibited greater uptake by HUVEC compared to CD47- EVs, but the CD47 antibody did not inhibit their uptake. Global and targeted analyses of transcripts demonstrated that treatment of HUVEC with EVs derived from MDA-MB-231 breast carcinomas cells altered pathways associated with tumor necrosis factor-alpha signaling, angiogenesis, lymphangiogenesis, endothelial-mesenchymal transition, and extracellular matrix. EVs from triple-negative MDA-MB-231 cells were more active than EVs from less metastatic breast carcinoma cell lines. Treatment with MDA-MB 231 EVs down-regulated VEGFR2 mRNA expression and tyrosine phosphorylation while enhancing phosphorylation of the tyrosine phosphatase SHP2. VEGFR2 expression and phosphorylation in HUVEC was further inhibited by the CD47 antibody. Consistent with the observed changes in endothelial-mesenchymal transition genes and SHP2, treatment with MDA-MB-231-derived EVs decreased Zeb1 protein levels in HUVEC, whereas the CD47 antibody increased Zeb1 levels. The induction of E-selectin and other known targets of tumor necrosis factor-alpha signaling by EVs was also enhanced by the CD47 antibody, and E-selectin was the most up-regulated transcript following CD47 antibody treatment alone. These studies reveal several mechanisms by which therapeutics targeting CD47 could modulate tumor growth by altering the cross talk between cancer-derived EVs and nonmalignant cells in the tumor stroma. PMID- 29188482 TI - The association of alcohol use and quality of life in depressed and non-depressed individuals: a cross-sectional general population study. AB - PURPOSE: To compare the associations of alcohol-related variables with Quality of Life (QoL) in depressed and non-depressed individuals of the general population. METHODS: This cross-sectional study utilized data from the FINRISK 2007 general population survey. A subsample (n = 4020) was invited to participate in an interview concerning alcohol use. Of them, 2215 (1028 men, 1187 women; response rate 55.1%) were included in the analyses. Bivariate associations between mean weekly alcohol consumption, frequency of binge drinking, Alcohol Use Disorders Identification Test (AUDIT)-score and QoL were analysed according to categorization into depressed and non-depressed using the Beck Depression Inventory, Short Form. Linear regression models were calculated in order to determine the associations of the alcohol variables and QoL after adjusting for socio-demographic variables as well as somatic and mental illness. RESULTS: Depressed individuals had lower mean QoL and higher AUDIT-scores than non depressed respondents. Bivariate correlations showed that mean weekly alcohol consumption, frequency of binge drinking and AUDIT-scores were statistically significantly associated with impaired QoL in depressed individuals. Abstinence was not associated with QoL. After adjustment for covariates, frequency of binge drinking and AUDIT-score were statistically significantly associated with QoL in depressed individuals and AUDIT-score in the non-depressed group. When analysing all respondents regardless of depression, both AUDIT-score and binge drinking were associated with QoL. CONCLUSIONS: Of the alcohol-related variables, binge drinking and alcohol problems indicated by AUDIT-score contributed to impaired QoL in depressed individuals and both should be assessed as part of the clinical management of depression. PMID- 29188481 TI - Using case management in a universal health coverage system to improve quality of life of frequent Emergency Department users: a randomized controlled trial. AB - PURPOSE: Frequent Emergency Department users are likely to experience poor quality of life (QOL). Case management interventions are efficient in responding to the complex needs of this population, but their effects on QOL have not been tested yet. Therefore, the aim of our study was to examine to what extent a case management intervention improved frequent Emergency Department users' QOL in a universal health coverage system. METHODS: Data were part of a randomized controlled trial designed to improve frequent Emergency Department users' QOL at the Lausanne University Hospital, Switzerland. A total of 250 frequent Emergency Department users (>= 5 attendances during the previous 12 months) were randomly assigned to the control (n = 125) or the intervention group (n = 125). The latter benefited from case management intervention. QOL was evaluated using the WHOQOL BREF at baseline, two, five and a half, nine, and twelve months later. It included four dimensions: physical health, psychological health, social relationship, and environment. Linear mixed-effects models were used to analyze the change in the patients' QOL over time. RESULTS: Patients' QOL improved significantly (p < 0.001) in both groups for all dimensions after two months. However, environment QOL dimension improved significantly more in the intervention group after 12 months. CONCLUSIONS: Environment QOL dimension was the most responsive dimension for short-term interventions. This may have been due to case management's assistance in obtaining income entitlements, health insurance coverage, stable housing, or finding general health care practitioners. Case management in general should be developed to enhance frequent users' QOL. TRIAL REGISTRATION: http://www.clinicaltrials.gov , Unique identifier: NCT01934322. PMID- 29188483 TI - Minimal clinically important differences in the EORTC QLQ-C30 and brief pain inventory in patients undergoing re-irradiation for painful bone metastases. AB - PURPOSE: The EORTC QLQ-C30 and the Brief Pain Inventory (BPI) are validated tools for measuring quality of life (QOL) and the impact of pain in patients with advanced cancer. Interpretation of these instrument scores can be challenging and it is difficult to know what numerical changes translate to clinically significant impact in patients' lives. To address this issue, our study sought to establish the minimal clinically important differences (MCID) for these two instruments in a prospective cohort of patients with advanced cancer and painful bone metastases. METHODS: Both anchor-based and distribution-based methods were used to estimate the MCID scores from patients enrolled in a randomized phase III trial evaluating two different re-irradiation treatment schedules. For the anchor based method, the global QOL item from the QLQ-C30 was chosen as the anchor. Spearman correlation coefficients were calculated for all items and only those items with moderate or better correlation (|r| >= 0.30) with the anchor were used for subsequent analysis. A 10-point difference in the global QOL score was used to classify improvement and deterioration, and the MCID scores were calculated for each of these categories. These results were compared with scores obtained by the distribution-method, which estimates the MCID purely from the statistical characteristics of the sample population. RESULTS: A total of 375 patients were included in this study with documented pain responses and completed QOL questionnaires at 2 months. 9/14 items in the QLQ-C30 and 6/10 items in the BPI were found to have moderate or better correlation with the anchor. For deterioration, statistically significant MCID scores were found in all items of the QLQ-C30 and BPI. For improvement, statistically significant MCID scores were found in 7/9 items of the QLQ-C30 and 2/6 items of the BPI. The MCID scores for deterioration were uniformly higher than the MCIDs for improvement. Using the distribution-based method, there was good agreement between the 0.5 standard deviation (SD) values and anchor-based scores for deterioration. For improvement, there was less agreement and the anchor-based scores were lower than the 0.5 SD values obtained from the distribution-based method. CONCLUSION: We present MCID scores for the QLQ-C30 and BPI instruments obtained from a large cohort of patients with advanced cancer undergoing re-irradiation for painful bone metastases. The results from this study were compared to other similar studies which showed larger MCID scores for improvement compared to deterioration. We hypothesize that disease trajectory and patient expectations are important factors in understanding the contrasting results. The results of this study can guide clinicians and researchers in the interpretation of these instruments. PMID- 29188484 TI - An evaluation of the structural validity of the shoulder pain and disability index (SPADI) using the Rasch model. AB - PURPOSE: The shoulder pain and disability index (SPADI) has been extensively evaluated for its psychometric properties using classical test theory (CTT). The purpose of this study was to evaluate its structural validity using Rasch model analysis. METHODS: Responses to the SPADI from 1030 patients referred for physiotherapy with shoulder pain and enrolled in a prospective cohort study were available for Rasch model analysis. Overall fit, individual person and item fit, response format, dependence, unidimensionality, targeting, reliability and differential item functioning (DIF) were examined. RESULTS: The SPADI pain subscale initially demonstrated a misfit due to DIF by age and gender. After iterative analysis it showed good fit to the Rasch model with acceptable targeting and unidimensionality (overall fit Chi-square statistic 57.2, p = 0.1; mean item fit residual 0.19 (1.5) and mean person fit residual 0.44 (1.1); person separation index (PSI) of 0.83. The disability subscale however shows significant misfit due to uniform DIF even after iterative analyses were used to explore different solutions to the sources of misfit (overall fit (Chi-square statistic 57.2, p = 0.1); mean item fit residual 0.54 (1.26) and mean person fit residual 0.38 (1.0); PSI 0.84). CONCLUSIONS: Rasch Model analysis of the SPADI has identified some strengths and limitations not previously observed using CTT methods. The SPADI should be treated as two separate subscales. The SPADI is a widely used outcome measure in clinical practice and research; however, the scores derived from it must be interpreted with caution. The pain subscale fits the Rasch model expectations well. The disability subscale does not fit the Rasch model and its current format does not meet the criteria for true interval-level measurement required for use as a primary endpoint in clinical trials. Clinicians should therefore exercise caution when interpreting score changes on the disability subscale and attempt to compare their scores to age- and sex stratified data. PMID- 29188486 TI - Phase-field modelling of gravity-capillary waves on a miscible interface. AB - Using the approach of direct numerical simulations we investigate the gravity capillary waves induced on a horizontal interface between two slowly miscible liquids. It is assumed that the liquids are just brought into contact, and thus the interface is slowly smeared by the action of interfacial diffusion. It is also assumed that the initial shape of the interface is distorted by harmonic perturbations, which results in the development of the gravity-capillary surface waves. The evolution of the binary mixture is modelled on the basis of the phase field method. Our results show that in the limiting case of negligible diffusion the classical dispersion relations for immiscible interfaces can be reproduced. Although, for the waves with shorter wavelengths such an agreement is more difficult to obtain. The interfacial diffusion brings an additional dissipation to the fluid system, strongly damping the development of the shorter waves. We also show that the mixing (or the transition of a binary system to the state of thermodynamic equilibrium) is intensified by the presence of the surface waves, and this effect is more important when the liquids are slowly miscible, i.e. when the interfacial diffusion is weak. PMID- 29188485 TI - Prospective associations of social isolation and loneliness with poor sleep quality in older adults. AB - PURPOSE: There is evidence for negative associations between social isolation and loneliness and sleep quality in older adults. However, it is unclear to what extent these two factors independently affect sleep quality. This study examined the simultaneous associations of social isolation and loneliness with sleep quality in a longitudinal study of older adults. METHODS: Data were analyzed from the Social Environment and Biomarkers of Aging Study in Taiwan collected in 2000 and 2006, involving a cohort of 639 participants (mean age = 66.14, SD 7.26). Poisson regression models were conducted to examine the association of social isolation and/or loneliness with sleep quality at follow-up after adjusting for multiple confounding variables. RESULTS: Univariate analysis showed that sleep quality was inversely associated with both social isolation and loneliness. After demographic, health, cognitive factors, and depressive symptoms were controlled in multivariable analysis, social isolation at the baseline still predicted poor sleep quality 6 years later (incident rate ratio, IRR 1.14; 95% CI 1.04-1.24; p < 0.01), while the association between loneliness and sleep quality was no longer significant (IRR 1.08; 95% CI 0.94-1.23; p = 0.27). The results were unchanged when participants who had poor sleep quality at the baseline were excluded from the analysis. CONCLUSIONS: These findings confirm an adverse effect of social isolation on the sleep quality of older adults, but indicate that this effect is independent of loneliness. Social isolation and loneliness seem to have distinct pathways in affecting the sleep quality of older adults. PMID- 29188487 TI - Sodium Metabisulfite: Effects on Ionic Currents and Excitotoxicity. AB - How sodium metabisulfite (SMB; Na2S2O5), a popular food preservative and antioxidant, interacts with excitable membrane and induces excitotoxicity is incompletely understood. In this study, the patch-clamp technique was used to investigate and record the electrophysiological effect of SMB on electrically excitable HL-1 cardiomyocytes and NSC-34 neurons, as well as its relationship to pilocarpine-induced seizures and neuronal excitotoxicity in rats. We used Western blotting, to analyze sodium channel expression on hippocampi after chronic SMB treatment. It was found that voltage-gated Na+ current (I Na) was stimulated, and current inactivation and deactivation were slowed in SMB-treated (30 MUM) HL-1 cardiomyocytes. SMB-induced increases of I Na were attenuated in cells treated with ranolazine (10 MUM) or eugenol (30 MUM). The current-voltage relationship of I Na shifted to slightly more negative potentials in SMB-treated cells, the peak I Na with an EC50 value of 18 MUM increased, and the steady-state inactivation curve of I Na shifted to a more positive potential. However, the tail component of the rapidly activating delayed-rectifier K+ current (I Kr) was dose dependently inhibited. Cell-attached voltage-clamp recordings in SMB-treated cells showed that the frequency of action currents and prolonged action potential were higher. In SMB-treated NSC-34 neurons, the peak I Na was higher; however, neither the time to peak nor the inactivation time constant (I Na) changed. Pilocarpine-induced seizures were exacerbated, and acute neuronal damage and chronic mossy fiber sprouting increased in SMB-treated rats. Western blotting showed higher expression of the sodium channel in cells after chronic SMB treatment. We conclude that SMB contributes to the sodium channel-activating mechanism through which it alters cellular excitability and excitotoxicity in wide-spectrum excitable cells. PMID- 29188488 TI - Lipopolysaccharide-Induced Microglia Activation Promotes the Survival of Midbrain Dopaminergic Neurons In Vitro. AB - Microglia are the resident immune cells of the central nervous system (CNS) and respond to a variety of endogenous and exogenous stimuli in order to restore cell and tissue homeostasis. Lipopolysaccharide (LPS) is one of these exogenous stimuli, constitutes a major component of the outer membrane of Gram-negative bacteria, and binds to the microglial pattern recognition receptor Toll-like receptor 4 (TLR4). LPS-induced microglia activation is believed to promote neurodegeneration by release of neurotoxic factors such as interleukin-1beta, tumor necrosis factor alpha, or nitric oxide. In the present study, we investigated whether the physical presence of microglia is required to promote neurotoxicity and whether microglia-derived factors are essential. Interestingly, we observed that dopaminergic (mDA) neuron survival was only affected in mixed neuron-glia cultures containing microglia but not in neuron-enriched cultures. Moreover, we clearly demonstrate that microglia-conditioned medium (MCM) after LPS treatment increased mDA neuron survival, process numbers as well as process length. The observed protective effects of MCM was rather caused by microglia derived factors and only partially dependent on the increase in reactive astrocytes. These results indicate that LPS-induced microglia activation does not necessarily have detrimental effects on mDA neurons and further support the hypothesis that activated microglia support neuron survival by release of neurotrophic and neuroprotective factors. PMID- 29188489 TI - Does the Prostate Imaging-Reporting and Data System (PI-RADS) version 2 improve accuracy in reporting anterior lesions on multiparametric magnetic resonance imaging (mpMRI)? AB - INTRODUCTION: Multiparametric MRI (mpMRI) is useful in detecting anterior prostate tumours. Due to the location of anterior tumours, they are often diagnosed with a large size and may be suspicious for extra-prostatic extension (EPE). We aim to evaluate whether PI-RADS v2 is more accurate in assessing anterior prostate lesions identified on mpMRI compared to PI-RADS v1. METHODS: Patients with anterior prostate lesions diagnosed on mpMRI who proceeded to a cognitive fusion transperineal prostate biopsy were identified. Each mpMRI was blinded and read by two experienced prostate MRI radiologists and assigned a PI RADS v1 and PI-RADS v2 score, and the presence of EPE was estimated. Correlation was made with transperineal histopathology and, where relevant, radical prostatectomy histopathology. Concordance measures between PI-RADS v1 and PI-RADS v2, and between examiners of the same PI-RADS score were calculated using a weighted kappa. RESULTS: Fifty-eight consecutive men were identified. Concordance between the examiners for PI-RADS v1 and for v2 showed substantial agreement (version 1: weighted kappa 0.71; version 2: weighted kappa 0.69). There was no difference in accuracy when using PI-RADS v1 or PI-RADS v2 to predict clinically significant cancer. There was poor correlation between EPE measured on mpMRI compared with EPE in radical prostatectomy histopathology. CONCLUSION: PI-RADS v2 is reproducible between radiologists but does not have improved accuracy for diagnosing anterior tumours of the prostate when compared to PI-RADS v1. Multiparametric MRI is accurate at detecting anterior tumours with a sensitivity of 86-88%. PMID- 29188490 TI - IgG4-Related Disease of the Appendix. PMID- 29188491 TI - Primary Colonic Lymphoma. AB - Primary colonic lymphoma is a rare large bowel malignancy usually found in the cecum or rectosigmoid junction. Because of its non-specific symptoms, patients often present with advanced disease requiring surgical intervention. Nevertheless, resection followed by chemotherapy appears to offer the best prognosis. PMID- 29188492 TI - Investigating the effects of subconcussion on functional connectivity using mass univariate and multivariate approaches. AB - There are concerns about the effects of subconcussive head impacts in sport, but the effects of subconcussion on brain connectivity are not well understood. We hypothesized that college football players experience changes in brain functional connectivity not found in athletes competing in lower impact sports or healthy controls. These changes may be spatially heterogeneous across participants, requiring analysis methods that go beyond mass-univariate approaches commonly used in functional MRI (fMRI). To test this hypothesis, we analyzed resting-state fMRI data from college football (n = 15), soccer (n = 12), and lacrosse players (n = 16), and controls (n = 29) collected at preseason and postseason time points. Regional homogeneity (ReHo) and degree centrality (DC) were calculated as measures of local and long-range functional connectivity, respectively. Standard voxel-wise analysis and paired support vector machine (SVM) classification studied subconcussion's effects on local and global functional connectivity. Voxel-wise analyses yielded minimal findings, but SVM classification had high accuracy for college football's ReHo (87%, p = 0.009) and no other group. The findings suggest subconcussion results in spatially heterogeneous changes in local functional connectivity that may only be detectible with multivariate analyses. To determine if voxel-wise and SVM analyses had similar spatial patterns, region-average t-statistic and SVM weight values were compared using a measure of ranking distance. T-statistic and SVM weight rankings exhibited significantly low ranking distance values for all groups and metrics, demonstrating that the analyses converged on a similar underlying effect. Overall, this research suggests that subconcussion in football may produce local functional connectivity changes similar to concussion. PMID- 29188493 TI - Lipid Droplet Fusion in Mammary Epithelial Cells is Regulated by Phosphatidylethanolamine Metabolism. AB - Mammary epithelial cells (MEC) secrete fat in the form of milk fat globules (MFG) which are found in milk in diverse sizes. MFG originate from intracellular lipid droplets, and the mechanism underlying their size regulation is still elusive. Two main mechanisms have been suggested to control lipid droplet size. The first is a well-documented pathway, which involves regulation of cellular triglyceride content. The second is the fusion pathway, which is less-documented, especially in mammalian cells, and its importance in the regulation of droplet size is still unclear. Using biochemical and molecular inhibitors, we provide evidence that in MEC, lipid droplet size is determined by fusion, independent of cellular triglyceride content. The extent of fusion is determined by the cell membrane's phospholipid composition. In particular, increasing phosphatidylethanolamine (PE) content enhances fusion between lipid droplets and hence increases lipid droplet size. We further identified the underlying biochemical mechanism that controls this content as the mitochondrial enzyme phosphatidylserine decarboxylase; siRNA knockdown of this enzyme reduced the number of large lipid droplets threefold. Further, inhibition of phosphatidylserine transfer to the mitochondria, where its conversion to PE occurs, diminished the large lipid droplet phenotype in these cells. These results reveal, for the first time to our knowledge in mammalian cells and specifically in mammary epithelium, the missing biochemical link between the metabolism of cellular complex lipids and lipid-droplet fusion, which ultimately defines lipid droplet size. PMID- 29188494 TI - Menin Modulates Mammary Epithelial Cell Numbers in Bovine Mammary Glands Through Cyclin D1. AB - Menin, the protein encoded by the MEN1 gene, is abundantly expressed in the epithelial cells of mammary glands. Here, we found MEN1/menin expression slowly decreased with advancing lactation but increased by the end of lactation. It happened that the number of bovine mammary epithelial cells decreases since lactation, suggesting a role of menin in the control of mammary epithelial cell growth. Indeed, reduction of menin expression through MEN1-specific siRNA transfection in the bovine mammary epithelial cells caused cell growth arrest in G1/S phase. Decreased mRNA and protein expression of Cyclin D1 was observed upon MEN1 knockdown. Furthermore, menin was confirmed to physically bind to the promoter region of Cyclin D1 through a ChIP assay, indicating that menin plays a regulatory role in mammary epithelial cell cycle progression. Moreover, lower expression of MEN1/menin induced increased epithelial cell apoptosis and caused extracellular matrix remodeling by down-regulating its associated genes, such as DSG2 and KRT5, suggesting that menin's role may also be involved in the control of cell-cell adhesion in normal mammary glands. Taken together, our data revealed an unknown molecular function of menin in epithelial cell proliferation, which may be important in the regulation of lactation behavior of mammary glands. PMID- 29188495 TI - Protein Biomarkers and Neuroproteomics Characterization of Microvesicles/Exosomes from Human Cerebrospinal Fluid Following Traumatic Brain Injury. AB - Recently, there have been emerging interests in the area of microvesicles and exosome (MV/E) released from brain cells in relation to neurodegenerative diseases. However, only limited studies focused on MV/E released post-traumatic brain injury (TBI) as they highlight on the mechanistic roles of released proteins. This study sought to examine if CSF samples from severe TBI patients contain MV/E with unique protein contents. First, nanoparticle tracking analysis determined MV/E from TBI have a mode of 74-98 nm in diameter, while control CSF MV/E have a mode of 99-104 nm. Also, there are more MV/E were isolated from TBI CSF (27.8-33.6 * 108/mL) than from control CSF (13.1-18.5 * 108/mL). Transmission electron microscopy (TEM) visualization also confirmed characteristic MV/E morphology. Using targeted immunoblotting approach, we observed the presence of several known TBI biomarkers such as alphaII-spectrin breakdown products (BDPs), GFAP, and its BDPs and UCH-L1 in higher concentrations in MV/E from TBI CSF than their counterparts from control CSF. Furthermore, we found presynaptic terminal protein synaptophysin and known exosome marker Alix enriched in MV/E from human TBI CSF. In parallel, we conducted nRPLC-tandem mass spectrometry-based proteomic analysis of two control and two TBI CSF samples. Ninety-one proteins were identified with high confidence in MV/E from control CSF, whereas 466 proteins were identified in the counterpart from TBI CSF. MV/E isolated from human CSF contain cytoskeletal proteins, neurite-outgrowth related proteins, and synaptic proteins, extracellular matrix proteins, and complement protein C1q subcomponent subunit B. Taken together, following severe TBI, the injured human brain released increased number of extracellular microvesicles/exosomes (MV/E) into CSF. These TBI MV/E contain several known TBI biomarkers and previously undescribed brain protein markers. It is also possible that such TBI-specific MV/E might contain cell to cell communication factors related to both cell death signaling a well as neurodegeneration pathways. PMID- 29188496 TI - The differential expression of novel circular RNAs in an acute lung injury rat model caused by smoke inhalation. AB - Acute lung injury caused by smoke inhalation is a common severe clinical syndrome. This study aimed to investigate the potential expression of circular RNAs during acute lung injury triggered by smoke inhalation. The acute lung injury rat model was established with smoke inhalation from a self-made smoke generator. The occurrence of acute lung injury was validated by an analysis of the bronchoalveolar lavage fluid and hematoxylin-eosin (HE) staining of lung tissues. Next-generation sequencing and quantitative PCR were performed to identify the differentially expressed circular RNAs associated with acute lung injury that was caused by smoke inhalation. The circular form of the identified RNAs was finally verified by multiple RT-PCR-based assays. The bronchoalveolar lavage fluid (BALF) and lung tissue analysis showed that smoke inhalation successfully induced acute injury in rats, as evidenced by the significantly altered cell numbers, including macrophages, neutrophils, and red blood cells, disrupted cell lining, and increased levels of interleukin-1beta, tumor necrosis factor-alpha, and IL-8 in lung tissues. Ten significantly differentially expressed circular RNAs were identified with next-generation sequencing and RT PCR. The circular form of these RNAs was verified by multiple RT-PCR-based assays. In conclusion, the identified circular RNAs were prevalently and differentially expressed in rat lungs after acute lung injury caused by smoke inhalation. PMID- 29188497 TI - Bexarotene, a Selective RXRalpha Agonist, Reverses Hypotension Associated with Inflammation and Tissue Injury in a Rat Model of Septic Shock. AB - Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors that can activate or inhibit the expression of many target genes by forming a heterodimer complex with the retinoid X receptor (RXR). The aim of this study was to investigate effects of bexarotene, a selective RXRalpha agonist, on the changes in renal, cardiac, hepatic, and pulmonary expression/activity of inducible nitric oxide synthase (iNOS) and cytochrome P450 (CYP) 4F6 in relation to PPARalpha/beta/gamma-RXRalpha heterodimer formation in a rat model of septic shock. Rats were injected with dimethyl sulfoxide or bexarotene 1 h after administration of saline or lipopolysaccharide (LPS). Mean arterial pressure (MAP) and heart rate (HR) were recorded from rats, which had received either saline or LPS before and after 1, 2, 3, and 4 h. Serum iNOS, LTB4, myeloperoxidase (MPO), and lactate dehydrogenase (LDH) levels as well as tissue iNOS and CYP4F6 mRNA expression in addition to PPARalpha/beta/gamma and RXRalpha proteins were measured. LPS-induced decrease in MAP and increase in HR were associated with a decrease in PPARalpha/beta/gamma-RXRalpha heterodimer formation and CYP4F6 mRNA expression. LPS also caused an increase in systemic iNOS, LTB4, MPO, and LDH levels as well as iNOS mRNA expression. Bexarotene at 0.1 mg/kg (i.p.) prevented the LPS-induced changes, except tachycardia. The results suggest that increased formation of PPARalpha/beta/gamma-RXRalpha heterodimers and CYP4F6 expression/activity in addition to decreased iNOS expression contributes to the beneficial effect of bexarotene to prevent the hypotension associated with inflammation and tissue injury during rat endotoxemia. PMID- 29188498 TI - Umbelliferone Alleviates Myocardial Ischemia: the Role of Inflammation and Apoptosis. AB - The present study was to investigate cardioprotective effects of umbelliferone (Umb) on coronary artery ligation-induced myocardial ischemia. The model of myocardial ischemia (MI) was induced by ligatured the left anterior descending coronary artery of SD rats. ST-segment elevation, lactate dehydrogenase (LDH), creatine kinase (CK), catalase (SOD), malondialdehyde (MDA), inflammatory cytokines, Toll-like receptors (TLRs)/nuclear factor (NF)-kappaBp65 pathway, and apoptosis were evaluated in rats treated with or without Umb. The results showed that Umb treatment could significantly decrease the elevation of the ST segment of electrocardiograph (ECG), the myocardial infarct size of MI significantly. The levels of LDH, CK, and MDA were suppressed, and the content of SOD was enhanced with Umb. The elevated concentration of inflammatory cytokines such as tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1beta), and IL-6 in MI rats was effectively reversed by the Umb administration. Also, TLR/NF-kappaB and apoptosis-related proteins in MI rats were restored respectively by Umb treatment. The protective effect of Umb against MI injury might be associated with inflammation and apoptosis pathway.

Surgeons play a central role in ACT treatments by performing resection of tumors from which TILs are isolated. It is important that surgeons have familiarity with this emerging treatment method because it is increasingly performed for an expanding variety of solid tumors at institutions around the world.

PMID- 29188501 TI - Correlation Between Biomarker Candidate Proteins with the Effect of Neoadjuvant Chemoradiation Therapy on Esophageal Squamous Cell Carcinoma. AB - BACKGROUND: While chemoradiation therapy (CRT) is one of the most useful treatments for esophageal squamous cell carcinoma (ESCC), it is important to predict response prior to treatment by using markers because some patients respond well and others do not. METHODS: Fifty-nine patients with ESCC were treated with neoadjuvant CRT at the Kagoshima University Hospital. The expression of seven types of biomarker candidate proteins in biopsy specimens of untreated primary tumors was evaluated to determine whether it correlated with response and prognosis. RESULTS: The positive expression rates were 47% for p53, 83% for CDC25B, 68% for 14-3-3sigma, 76% for p53R2, 75% for ERCC1, 32% for Gli-1, and 54% for Nrf2. In terms of histological response, tumor grade of the 59 patients was 48.8% for grade 1 as the non-responder, 29.2% for grade 2, and 22.0% for grade 3 as the responder. CRT was significantly effective in p53(-), p53R2(-), ERCC1(-), and Nrf2(-) tumors, while p53(-), p53R2(-), and ERCC1(-) were factors independently correlated with effective histological response. Their combined expression of two or three negative expressions had 100% effective response and was a significant prognostic factor. CONCLUSION: Our results suggest that two or three negative expressions of p53, p53R2, and ERCC1 in biopsy specimens of primary tumors were associated with a favorable response to CRT for ESCC. Assessment of tumor suppressor and DNA repair protein expressions in biopsy specimens may be useful for the potential utility of CRT therapy for patients with ESCC prior to treatment. PMID- 29188502 TI - Small Scale Production of Recombinant Adeno-Associated Viral Vectors for Gene Delivery to the Nervous System. AB - Adeno-associated viral vectors have numerous applications in neuroscience, including the study of gene function in health and disease, targeting of light sensitive proteins to anatomically distinct sets of neurons to manipulate neuronal activity (optogenetics), and the delivery of fluorescent protein to study anatomical connectivity in the brain. Moreover several phase I/II clinical trials for gene therapy of eye and brain diseases with adeno-associated viral vectors have shown that these vectors are well tolerated by human patients. In this chapter we describe a detailed protocol for the small scale production of recombinant adeno-associated viral vectors. This protocol can be executed by investigators with experience in cell culture and molecular biological techniques in any well-equipped molecular neurobiology laboratory. With this protocol we typically obtain research batches of 100-200 MUL that range in titer from 5 * 1012 to 2 * 1013 genomic copies/mL. PMID- 29188503 TI - Small and Micro-Scale Recombinant Adeno-Associated Virus Production and Purification for Ocular Gene Therapy Applications. AB - Over the past two decades recombinant adeno-associated virus (rAAV) vectors have emerged as the gold standard for transferring genetic material to cells of the retina. The ability to effectively produce small batches of rAAV vector at high enough purity for in vitro and in vivo applications in a cost-effective manner is paramount. This is particularly the case when conducting preclinical experiments to screen novel serotypes, promoters or transgenes, where production of numerous vector batches is required. Current vector production methods often produce large quantities of vector, limiting the cost-effectiveness and practicality of such screening experiments, which often require only small volumes of vector to carry out. Herein, we describe a method to produce high titer (1012-1013 vector genomes (vg)/mL) rAAV vector on small (~100 MUL) or micro (~15 MUL) scale for in vitro and in vivo applications. PMID- 29188504 TI - Design and Development of AAV-based Gene Supplementation Therapies for Achromatopsia and Retinitis Pigmentosa. AB - Achromatopsia (ACHM) and retinitis pigmentosa (RP) are inherited disorders caused by mutations in cone and rod photoreceptor-specific genes, respectively. ACHM strongly impairs daylight vision, whereas RP initially affects night vision and daylight vision at later stages. Currently, gene supplementation therapies utilizing recombinant adeno-associated virus (rAAV) vectors are being developed for various forms of ACHM and RP. In this chapter, we describe the procedure of designing and developing specific and efficient rAAV vectors for cone- and rod specific gene supplementation. PMID- 29188505 TI - Development of Multigenic Lentiviral Vectors for Cell-Specific Expression of Antiangiogenic miRNAs and Protein Factors. AB - Generation of lentivirus (LV)-based vectors holding multiple gene cassettes for coexpression of several therapeutic factors provides potent tools in both gene delivery studies as well as in gene therapy. Here we describe the development of such multigenic LV gene delivery vectors enabling cell-specific coexpression of antiangiogenic microRNA (miRNA) and protein factors and, if preferred, a fluorescent reporter, from RNApol(II)-driven expression cassettes orientated in a back-to-back fashion. This configuration may contribute to the development of new combination therapies for amelioration of diseases involving intraocular neovascularization including exudative age-related macular degeneration (AMD). PMID- 29188506 TI - Design and In Vitro Use of Antisense Oligonucleotides to Correct Pre-mRNA Splicing Defects in Inherited Retinal Dystrophies. AB - Antisense oligonucleotides (AONs) are small molecules able to bind to the pre mRNA and modulate splicing. The increasing amount of intronic mutations leading to pseudoexon insertion in genes underlying inherited retinal dystrophies (IRDs) has highlighted the potential of AONs as a therapeutic tool for these disorders. Here we describe how to design and test AON molecules in vitro in order to correct pre-mRNA splicing defects involved in IRDs. PMID- 29188507 TI - Three-Dimensional Co-Culture Bioassay for Screening of Retinal Gene Delivery Systems. AB - Herein we describe a three-dimensional co-culture bioassay protocol designed to assess the therapeutic potential of the proteins expressed from gene delivery transfected cells through the evaluation of expressed protein bioavailability and bioactivity. Using a combination of enzyme-linked immunosorbent assay (ELISA) and immunofluorescent-based neurite length profiling methodologies, the bioavailability of the secreted therapeutic protein in the medium can be quantitated, and the bioactivity of the secreted therapeutic protein can also be evaluated through neurite length profiling, respectively. The versatility and rationale of this bioassay could serve as a useful screening tool in the development of retinal gene delivery systems. PMID- 29188508 TI - Retinal Gene Therapy for Choroideremia: In Vitro Testing for Gene Augmentation Using an Adeno-Associated Viral (AAV) Vector. AB - As gene therapy of choroideremia is becoming a clinical reality, there is a need for reliable and sensitive assays to determine the expression of exogenously delivered Rab Escort Protein-1 (REP1), in particular to test new gene therapy vectors and as a quality control screen for clinical vector stocks. Here we describe an in vitro protocol to test transgene expression following AAV2/2-REP1 transduction of a human cell line. Gene augmentation can be confirmed by western blot and quantification of the fold-increase of human REP1 levels over untransduced controls. PMID- 29188509 TI - In Vivo Electroporation of Developing Mouse Retina. AB - In vivo electroporation enables the transformation of retinal tissue with engineered DNA plasmids, facilitating the selective expression of desired gene products. This method achieves plasmid transfer via the application of an external electrical field, which both generates a transient increase in the permeability of cell plasma membranes, and promotes the incorporation of DNA plasmids by electrophoretic transfer through the permeabilized membranes. Here we describe a method for the preparation, injection, and electroporation of DNA plasmids into neonatal mouse retinal tissue. This method can be utilized to perform gain of function or loss of function studies in the mouse. Experimental design is limited only by construct availability. PMID- 29188510 TI - Methods for In Vivo CRISPR/Cas Editing of the Adult Murine Retina. AB - Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR associated protein (Cas) is used by some bacteria and most archaea to protect against viral phage intrusion and has recently been adapted to allow for efficient editing of the mammalian genome. Whilst CRISPR/Cas-based technology has been used to modify genes in mammalian cells in vitro, delivery of CRISPR/Cas system into mammalian tissue and/or organs is more difficult and often requires additional vectors. With the use of adeno-associated virus (AAV) gene delivery system, active CRISPR/Cas enzyme can be maintained for an extended period of time and enable efficient editing of genome in the retina in vivo. Herein we outline the method to edit the genome in mouse retina using a dual AAV vector -mediated CRISPR/Cas9 system. PMID- 29188511 TI - AAV Gene Augmentation Therapy for CRB1-Associated Retinitis Pigmentosa. AB - Mutations in the CRB1 gene account for around 10,000 persons with Leber congenital amaurosis (LCA) and 70,000 persons with retinitis pigmentosa (RP) worldwide. Therefore, the CRB1 gene is a key target in the fight against blindness. A proof-of-concept for an adeno-associated virus (AAV)-mediated CRB2 gene augmentation therapy for CRB1-RP was recently described. Preclinical studies using animal models such as knockout or mutant mice are crucial to obtain such proof-of-concept. In this chapter we describe a technique to deliver AAV vectors, into the murine retinas, via the subretinal route. We also present protocols to detect expression of the therapeutic protein by fluorescence immunohistochemistry and to perform histological studies using ultra-thin sections stained with toluidine blue. These techniques in combination with electroretinography and visual behavior tests are in principle sufficient to obtain proof-of-concept for new gene therapies. PMID- 29188512 TI - Dual AAV Vectors for Stargardt Disease. AB - Stargardt disease (STGD1), due to mutations in the large ABCA4 gene, is the most common inherited macular degeneration in humans. Attempts at developing gene therapy approaches for treatment of STGD1 are currently ongoing. Among all the vectors available for gene therapy of inherited retinal diseases, those based on adeno-associated viruses (AAV) are the most promising given the efficacy shown in various animal models and their excellent safety profile in humans, as confirmed in many ongoing clinical trials. However, one of the main obstacles for the use of AAV is their limited effective packaging capacity of about 5 kb. Taking advantage of the AAV genome's ability to concatemerize , others and we have recently developed dual AAV vectors to overcome this limit. We tested dual AAV vectors for ABCA4 delivery, and found that they transduce efficiently both mouse and pig photoreceptors , and rescue the Abca4-/- mouse retinal phenotype, indicating their potential for gene therapy of STGD1. This chapter details how we designed dual AAV vectors for the delivery of the ABCA4 gene and describes the techniques that can be explored to evaluate dual AAV transduction efficiency in vitro and in the retina, and their efficacy in the mouse model of STGD1. PMID- 29188513 TI - Optogenetic Retinal Gene Therapy with the Light Gated GPCR Vertebrate Rhodopsin. AB - In retinal disease, despite the loss of light sensitivity as photoreceptors die, many retinal interneurons survive in a physiologically and metabolically functional state for long periods. This provides an opportunity for treatment by genetically adding a light sensitive function to these cells. Optogenetic therapies are in development, but, to date, they have suffered from low light sensitivity and narrow dynamic response range of microbial opsins. Expression of light-sensitive G protein coupled receptors (GPCRs), such as vertebrate rhodopsin , can increase sensitivity by signal amplification , as shown by several groups. Here, we describe the methods to (1) express light gated GPCRs in retinal neurons, (2) record light responses in retinal explants in vitro, (3) record cortical light responses in vivo, and (4) test visually guided behavior in treated mice. PMID- 29188514 TI - CRISPR Repair Reveals Causative Mutation in a Preclinical Model of Retinitis Pigmentosa: A Brief Methodology. AB - CRISPR/Cas9 genome engineering is currently the leading genome surgery technology in most genetics laboratories. Combined with other complementary techniques, it serves as a powerful tool for uncovering genotype-phenotype correlations. Here, we describe a simplified protocol that was used in our publication, CRISPR Repair Reveals Causative Mutation in a Preclinical Model of Retinitis Pigmentosa, providing an overview of each section of the experimental process. PMID- 29188515 TI - In-Depth Functional Analysis of Rodents by Full-Field Electroretinography. AB - Full-field electroretinography (ERG) belongs to the gold-standard of electrophysiological test systems in ophthalmology and reflects the sum response of the entire retina to light stimulation. The assessment of the retinal function is a fundamental diagnostic technique not only in the clinical ophthalmology it is also indispensable in the ophthalmic research, in particular, in therapeutic approaches where the in vivo follow up of the benefit after treatment is absolutely necessary. Several current therapeutic approaches have demonstrated long-lasting amelioration in respective disease models and show promise for a successful translation to human patients. In this chapter we provide electroretinography protocols of experimental data which may serve as informative features for upcoming gene therapeutic approaches and clinical trials. PMID- 29188516 TI - Advanced Ocular Injection Techniques for Therapy Approaches. AB - Treatment approaches for inherited eye diseases require local therapeutic molecule delivery by intraocular injection. One important factor that can influence the study outcome is the quality of intraocular administration. The intracompartmental structure (e.g., vitreous) of the eye allows a sustainable release of therapeutic biologicals using an intravitreal delivery. The protocol described here aims at providing the details relevant to perform a transscleral pars plana intravitreal transfer in small eyes using a genetically modified stem cell system. The fact that cells and therewith visually distinct particles are implanted, allows for the assessment of the implantation site and the distribution, and possibilities for temporal follow up studies-hence, valuable information becomes available which can be used to fine-tune the intravitreal delivery technique. PMID- 29188517 TI - Neutralizing Antibodies Against Adeno-Associated Virus (AAV): Measurement and Influence on Retinal Gene Delivery. AB - Adeno-associated viral vectors have become widely used in the clinic for retinal gene therapy. Thanks to AAVs impeccable safety profile and positive functional outcomes in its clinical application, interest in retinal gene therapy has increased exponentially over the past decade. Although early clinical trials have shown there is little influence of neutralizing antibodies on the performance of AAV when vector is administered into the subretinal space, recent findings suggest neutralizing antibodies may play a role when AAV is delivered via the intravitreal route. These findings highlight the importance of microenvironment on gene delivery and stress the need for a versatile assay to screen subjects for the presence of AAV-neutralizing antibodies. Measuring NAb titers against AAV prior and after gene therapy will help us better understand the impact of preexisting immunity on gene transfer, especially when the vector is administered intravitreally. PMID- 29188519 TI - Subretinal and Intravitreal Retinal Injections in Monkeys. AB - Ocular anatomy and physiology in cynomolgus monkeys (Macacca fascicularis) are very similar to that found in the human visual system. Therefore and despite significant ethical and economical implications, these animals constitute an excellent model system for toxicology and biodistribution studies in the development of new and meaningful treatment strategies for ocular disorders. The methods for delivery of investigational new drugs (INDs) to the ocular tissue are virtually identical to the methods used in clinical practice. This protocol explains in detail the method of applying INDs to the vitreous cavity or the subretinal space in monkeys. PMID- 29188518 TI - Screening for Neutralizing Antibodies Against Natural and Engineered AAV Capsids in Nonhuman Primate Retinas. AB - Adeno-associated virus (AAV) has shown promise as a therapeutic gene delivery vector for inherited retinal degenerations in both preclinical disease models and human clinical trials. The retinas of nonhuman primates (NHPs) share many anatomical similarities to humans and are an important model for evaluating AAV gene delivery. Recent evidence has shown that preexisting immunity in the form of neutralizing antibodies (NABs) in NHPs strongly correlates with weak or lack of AAV transduction in the retina when administered intravitreally, work with translational implications. This necessitates prescreening of NHPs before intravitreal delivery of AAV. In this chapter, we describe a method for screening NHP serum for preexisting NABs. PMID- 29188520 TI - Production of iPS-Derived Human Retinal Organoids for Use in Transgene Expression Assays. AB - In vitro retinal organoid modeling from human pluripotent stem cells is becoming more common place in many ophthalmic laboratories worldwide. These organoids mimic human retinogenesis through formation of organized layered retinal structures that display markers for typical retinal cell types. Pivotally these humanized retinal models provide a stepping stone to the clinic as therapeutic tools and are expected to provide a promising alternative to current animal models. Thus pluripotent stem cell based healthy as well as diseased human retinal organoids are attractive for use in drug potency assays and gene augmentation therapeutics. Here we outline an established protocol for generation of these retinal organoids and how they can be used in conjunction with adeno associated virus vectors for transgene expression assays. PMID- 29188522 TI - Human Retinal Explant Culture for Ex Vivo Validation of AAV Gene Therapy. AB - Recombinant adeno-associated viral (AAV) vectors have been successfully employed as the mode of gene delivery in several clinical trials for the treatment of inherited retinal diseases to date. The design of such vectors is critical in determining cellular tropism and level of subsequent gene expression that may be achieved following viral delivery. Here we describe a system for living retinal tissue extraction, ex vivo culture, viral transduction and assessment of transgene expression that may be used to assess viral constructs for gene therapy in the human retina at a preclinical stage. PMID- 29188521 TI - AAV Serotype Testing on Cultured Human Donor Retinal Explants. AB - This protocol details on a screening method for infectivity and tropism of different serotypes of adeno-associated viruses (AAVs) on human retinal explants with cell-type specific or ubiquitous green fluorescent protein (GFP) expression vectors. Eyes from deceased adult human donors are enucleated and the retinas are isolated. Each retina is punched into eight to ten 6-mm equal pieces. WhatmanTM paper punches are placed on the retinas and the stack is transferred onto 24-well culture inserts with the photoreceptors facing the membrane. AAVs are applied on the retinal explant punches to allow transduction for 48 h. Retinas are nourished by a serum-free Neurobasal(r)-A based medium composition that allows extended culturing of explants containing photoreceptor inner and outer segments. The protocols include quality control measurements and histological staining for retina cells. The cost and time effective procedure permits AAV transgene expression assays, RNAi knockdown, and pharmacological intervention on human retinas for 21 days ex vivo. PMID- 29188524 TI - Recording and Analysis of the Human Clinical Electroretinogram. AB - The electroretinogram (ERG) represents the biopotential that is produced by the retina in response to a light stimulus. To date, it remains the best diagnostic tool to objectively evaluate the functional integrity of the normal or diseased retina. In the following pages we briefly review the necessary requirements in order to record and analyze the conventional clinical ERG. PMID- 29188523 TI - Visual Acuity Testing Before and After Intravitreal Injection of rAAV2-ND4 in Patients. AB - Gene therapy in ophthalmology has developed rapidly, and there has been a breakthrough in the treatment of Leber's hereditary optic neuropathy. After receiving an intravitreal injection of rAAV2-ND4, patients followed up over a certain time period showed a definite increase in visual acuity. Visual acuity testing is critical for assessing the efficacy of rAAV2-ND4 intravitreal injection. PMID- 29188525 TI - Recording and Analysis of Goldmann Kinetic Visual Fields. AB - Goldmann kinetic perimetry is a commonly used method of evaluating the peripheral visual field. Ongoing gene therapy trials have targeted the central retina, but have nonetheless often included Goldmann kinetic perimetry as part of extensive preinterventional and postinterventional assessment. Future gene therapy trials may target the entire retina through intravitreal injections, as have drug therapeutic trials, further necessitating the evaluation of function across the entire retina. In the following pages, we will briefly review the necessary steps to perform and quantify the visual field, using the conventional Goldmann perimeter and the Field Digitizer software (version 4.20; Johns Hopkins Technology Ventures, Baltimore, USA), respectively. PMID- 29188526 TI - Measuring Central Retinal Sensitivity Using Microperimetry. AB - Microperimetry is an increasingly often used method of assessing the sensitivity of the central macula, analyzing fixation capabilities and loci, and accurately combining structural and functional information, even in the absence of stable fixation. Ongoing gene therapy trials have targeted the central retina, and utilized microperimetry as a main outcome measure for changes in retinal function. In retinal treatment planning, microperimetry has been used to assess the potential therapeutic window of opportunity. In the following pages, we briefly review the necessary steps to perform the Macular Integrity Assessment (MAIA) microperimetry. PMID- 29188527 TI - Inspection of the Human Retina by Optical Coherence Tomography. AB - Optical coherence tomography (OCT) is a high-resolution, three-dimensional, noninvasive imaging modality to examine the human retina. Since the introduction of spectral domain (SD-) OCT-the currently most used variant of OCT-previously unknown details of in vivo retinal morphology of a broad variety of pathologies have become visible. This chapter explains the basic principles of the OCT technology, deals with possible pitfalls in OCT examination or analysis, and hints at the use of OCT technology in functional imaging. PMID- 29188528 TI - Vector Shedding and Immunogenicity Sampling for Retinal Gene Therapy. AB - There has been recent growth in the number and magnitude of clinical trials for various forms of retinal gene therapy. Because of regulatory requirements, and to better understand vector safety profiles, there is a need for standardised and effective methods to collect, process, and store biological samples taken from trial patients that can be used to assess the dissemination of the vector within bodily fluids and any systemic cellular and humoral immune responses. PMID- 29188529 TI - Spinal ependymomas in NF2: a surgical disease? AB - The management of spinal cord ependymomas in Neurofibromatosis Type 2 (NF2) has traditionally been conservative, in contrast to the management of sporadic cases; the assumption being that, in the context of NF2, they did not cause morbidity. With modern management and improved outcome of other NF2 tumours, this assumption, and therefore the lack of role for surgery, has been questioned. To compare the outcome of conservative treatment of spinal ependymomas in NF2 with surgical intervention in selected patients. Retrospective review at two NF2 centers, Manchester, UK and Paris/Lille, France. In Manchester patients were managed conservatively. In France surgery was a treatment option. Inclusion in the study was based on tumor length of greater than 1.5 cm. The primary parameter assessed was acquired neurological deficit measured by the Modified McCormick Outcome Score. 24 patients from Manchester and 46 patients from France were analyzed. From Manchester, 27% of these patients deteriorated during the course of follow-up. This effectively represents the natural history of ependymomas in NF2. Of the surgical cases, 23% deteriorated postoperatively, but only 2/18 (11%) of those operated on in the NF2 specialist centers. Comparison of the two specialist centers Manchester/France showed a significantly improved outcome (P = 0.012, chi2 test) in the actively surgical center. Spinal ependymomas produce morbidity. Surgery can prevent or improve this in selected cases but can itself can produce morbidity. Surgery should be considered in growing/symptomatic ependymomas, particularly in the absence of overwhelming tumor load where bevacizumab is the preferred option. PMID- 29188530 TI - Histopathological vascular investigation of the peritumoral brain zone of glioblastomas. AB - To date, no histopathological vascular investigation focusing on peritumoral brain zone (PBZ) has been reported for glioblastoma. We analyzed 10 newly diagnosed cases of glioblastomas. For these PBZs, histopathological investigation was performed by hematoxylin-eosin (H&E) staining and immunohistochemistry was analyzed for CD31, CD34, Factor VIII, VEGF, VEGFR-1/2, Ki67, p53 and nestin. Although it was difficult to identify PBZ by H&E, Ki67 and p53 staining, there were apparent differences in nestin staining among PBZ, tumor core (TC), and normal zone (NZ). Therefore, in this study, we divided PBZ from TC and NZ by nestin staining. Differences in histological features, microvessel density, expression of VEGF and its receptors were assessed for PBZ, TC and NZ. The microvessel density, as determined by counting CD31, CD34 and VEGF receptors, and VEGF-A expression were lower in PBZ than TC. The expression patterns for CD31, CD34 and VEGF receptors in vessels show dissociation in PBZ. In addition, the vascular characteristics of the PBZ may correlate with findings of radiographic imaging. We provide the first clinicopathological evidence that PBZ exhibits unique angiogenic characteristics. These in situ observations will help to elucidate the mechanisms of tumor recurrence. PMID- 29188531 TI - MiR-519d-3p suppresses breast cancer cell growth and motility via targeting LIM domain kinase 1. AB - Breast cancer is the most common female cancer in women, and its estrogen receptor (ER)-negative subtype (ENBC) and triple-negative subtype (TNBC) have unfavorable prognosis in comparison with ER-positive subtype. MiRNAs are small noncoding RNAs that bind to the 3'-UTR region of targeting mRNAs to regulate gene expression. Mir-519d-3p was found to be associated with breast cancer for its potential role in proliferation and metastasis. To explore its potential role and mechanism of miR-519d-3p in breast carcinogenesis, we determined whether miR-519d 3p regulates breast cancer cell proliferation and motility by performing wound healing assays and migration-invasion assays. We found that miR-519d-3p significantly inhibits proliferation and motility of ENBC and TNBC cells. Overexpression of miR-519d-3p arrested breast cancer cells in the G0/G1 phase and reduced the expression of CDK4, 6/Cyclin D1, and CDK2/Cyclin E1. It was reported that miR-519d-3p or miR-519d-3p expression was associated with cancer metastasis and clinical staging. Since LIM domain kinase 1 (LIMK1) was highly expressed in breast cancer and a major regulator of breast cancer growth and metastasis, we further demonstrated that LIMK1 is a potential target of miR-519d-3p by dual luciferase report assay. Mir-519d-3p decreases LIMK1 expression at mRNA and protein levels, and the protein level and phosphorylation of cofilin 1 (CFL1), one of the key downstream targets of LIMK1. Our findings suggest that miR-519d-3p regulates the LIMK1/CFL1 pathway in breast cancer and this new venue could be targeted for future breast cancer therapy. PMID- 29188532 TI - Lipopolysaccharide stimulates endogenous beta-glucuronidase via PKC/NF-kappaB/c myc signaling cascade: a possible factor in hepatolithiasis formation. AB - Hepatolithiasis is commonly encountered in Southeastern and Eastern Asian countries, but the pathogenesis mechanism of stone formation is still not well understood. Now, the role of endogenous beta-glucuronidase in pigment stones formation is being gradually recognized. In this study, the mechanism of increased expression and secretion of endogenous beta-glucuronidase during hepatolithiasis formation was investigated. We assessed the endogenous beta glucuronidase, c-myc, p-p65, and p-PKC expression in liver specimens with hepatolithiasis by immunohistochemical staining, and found that compared with that in normal liver samples, the expression of endogenous beta-glucuronidase, c myc, p-p65, and p-PKC in liver specimens with hepatolithiasis significantly increased, and their expressions were positively correlated with each other. Lipopolysaccharide (LPS) induced increased expression of endogenous beta glucuronidase and c-myc in hepatocytes and intrahepatic biliary epithelial cells in a dose- and time-dependent manner, and endogenous beta-glucuronidase secretion increased, correspondingly. C-myc siRNA transfection effectively inhibited the LPS-induced expression of endogenous beta-glucuronidase. Furthermore, NF-kappaB inhibitor pyrrolidine dithiocarbamate or PKC inhibitor chelerythrine could effectively inhibit the LPS-induced expression of c-myc and endogenous beta glucuronidase, and the expression of p-p65 was also partly inhibited by chelerythrine. Our clinical observations and experimental data indicate that LPS could induce the increased expression and secretion of endogenous beta glucuronidase via a signaling cascade of PKC/NF-kappaB/c-myc in hepatocytes and intrahepatic biliary epithelial cells, and endogenous beta-glucuronidase might play a possible role in the formation of hepatolithiasis. PMID- 29188533 TI - Effects of homocysteine and its related compounds on oxygen consumption of the rat heart tissue homogenate: the role of different gasotransmitters. AB - The objective of this study was to investigate in vitro effects of 10 uM DL homocysteine (DL-Hcy), DL-homocysteine thiolactone-hydrochloride (DL-Hcy TLHC), and L-homocysteine thiolactone-hydrochloride (L-Hcy TLHC) on the oxygen consumption of rat heart tissue homogenate, as well as the involvement of the gasotransmitters NO, H2S and CO in the effects of the most toxic homocysteine compound, DL-Hcy TLHC. The possible contribution of the gasotransmitters in these effects was estimated by using the appropriate inhibitors of their synthesis (N omega-nitro-L-arginine methyl ester (L-NAME), DL-propargylglycine (DL-PAG), and zinc protoporphyrin IX (ZnPPR IX), respectively). The oxygen consumption of rat heart tissue homogenate was measured by Clark/type oxygen electrode in the absence and presence of the investigated compounds. All three homocysteine-based compounds caused a similar decrease in the oxygen consumption rate compared to control: 15.19 +/- 4.01%, 12.42 +/- 1.01%, and 16.43 +/- 4.52% for DL-Hcy, DL-Hcy TLHC, or L-Hcy TLHC, respectively. All applied inhibitors of gasotransmitter synthesis also decreased the oxygen consumption rate of tissue homogenate related to control: 13.53 +/- 1.35% for L-NAME (30 uM), 5.32 +/- 1.23% for DL-PAG (10 uM), and 5.56 +/- 1.39% for ZnPPR IX (10 uM). Simultaneous effect of L-NAME (30 uM) or ZnPPR IX (10 uM) with DL-Hcy TLHC (10 uM) caused a larger decrease of oxygen consumption compared to each of the substances individually. However, when DL-PAG (10 uM) was applied together with DL-Hcy TLHC (10 uM), it attenuated the effect of DL-Hcy TLHC from 12.42 +/- 1.01 to 9.22 +/- 1.58%. In conclusion, cardiotoxicity induced by Hcy-related compounds, which was shown in our previous research, could result from the inhibition of the oxygen consumption, and might be mediated by the certain gasotransmitters. PMID- 29188534 TI - 1,25(OH)2-vitamin D3 upregulates glucose uptake mediated by SIRT1/IRS1/GLUT4 signaling cascade in C2C12 myotubes. AB - This study examined the hypothesis that 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) upregulates the insulin-independent signaling cascade of glucose metabolism. C2C12 myotubes were treated with high glucose (HG, 25 mM) and 1,25(OH)2D3 (0-50 nM). 1,25(OH)2D3 supplementation upregulated both insulin-independent (SIRT1) and insulin-dependent (p-IRS) signaling molecules, and stimulated the GLUT4 translocation, and glucose uptake in HG-treated myotubes. The effect of 1,25(OH)2D3 on IRS1 phosphorylation, GLUT4 translocation, and glucose uptake was attenuated in SIRT1-knockdown myotubes. Treatment with 1,25(OH)2D3, coupled with insulin, enhanced GLUT4 translocation and glucose uptake compared to treatment with either insulin or 1,25(OH)2D3 alone in HG-treated myotubes, which suggests that insulin-independent signaling molecules can contribute to the higher glucose metabolism observed in 1,25(OH)2D3 and insulin-treated cells. The data, therefore, suggest that 1,25(OH)2D3 increases glucose consumption by inducing SIRT1 activation, which in turn increases IRS1 phosphorylation and GLUT4 translocation in myotubes. PMID- 29188535 TI - Differential cellular responses by oncogenic levels of c-Myc expression in long term confluent retinal pigment epithelial cells. AB - c-Myc is a highly pleiotropic transcription factor known to control cell cycle progression, apoptosis, and cellular transformation. Normally, ectopic expression of c-Myc is associated with promoting cell proliferation or triggering cell death via activating p53. However, it is not clear how the levels of c-Myc lead to different cellular responses. Here, we generated a series of stable RPE cell clones expressing c-Myc at different levels, and found that consistent low level of c-Myc induced cellular senescence by activating AP4 in post-confluent RPE cells, while the cells underwent cell death at high level of c-Myc. In addition, high level of c-Myc could override the effect of AP4 on cellular senescence. Further knockdown of AP4 abrogated senescence-like phenotype in cells expressing low level of c-Myc, and accelerated cell death in cells with medium level of c Myc, indicating that AP4 was required for cellular senescence induced by low level of c-Myc. PMID- 29188536 TI - Inhibitory influence of natural flavonoids on human protein kinase CK2 isoforms: effect of the regulatory subunit. AB - CK2 is a pleiotropic, constitutively active protein kinase responsible for the phosphorylation of more than 300 physiological substrates. Typically, this enzyme is found in tetrameric form consisting of two regulatory subunits CK2beta and two catalytic subunits CK2alpha or CK2alpha'. Several natural occurring flavonoids were tested for their ability to inhibit both CK2 holoenzymes, CK2alpha2beta2 and CK2alpha'2beta2. We identified few substances selectively inhibiting only the alpha' subunit. Other compounds showed similar effect towards all four isoforms. In some cases, like chrysoeriol, pedalitin, apigenin, and luteolin, the alpha2beta2 holoenzyme was at least six times better inhibited than the free alpha subunit. Otherwise, we have found a luteolin derivative decreased the kinase activity of CK2alpha' with an IC50 value of 0.8 MUM, but the holoenzyme only with 9.5 uM. PMID- 29188538 TI - Analytical ultracentrifugation in structural biology. AB - Researchers in the field of structural biology, especially X-ray crystallography and protein nuclear magnetic resonance, are interested in knowing as much as possible about the state of their target protein in solution. Not only is this knowledge relevant to studies of biological function, it also facilitates determination of a protein structure using homogeneous monodisperse protein samples. A researcher faced with a new protein to study will have many questions even after that protein has been purified. Analytical ultracentrifugation (AUC) can provide all of this information readily from a small sample in a non destructive way, without the need for labeling, enabling structure determination experiments without any wasting time and material on uncharacterized samples. In this article, I use examples to illustrate how AUC can contribute to protein structural analysis. Integrating information from a variety of biophysical experimental methods, such as X-ray crystallography, small angle X-ray scattering, electrospray ionization-mass spectrometry, AUC allows a more complete understanding of the structure and function of biomacromolecules.

PMID- 29188537 TI - Pretreatment with quercetin prevents changes in lymphocytes E-NTPDase/E-ADA activities and cytokines secretion in hyperlipidemic rats. AB - Hyperlipidemia (HL) is a condition associated with endothelial dysfunction and inflammatory disorders. Purinergic system ectoenzymes play an important role in modulating the inflammatory and immune response. This study investigated whether the preventive treatment with quercetin is able to prevent changes caused by hyperlipidemia in the purinergic system, through the activities of E-NTPDase and E-ADA in lymphocytes, and quantify the nucleotides and nucleoside, and the secretion of anti- and proinflammatory cytokines. Animals were divided into saline/control, saline/quercetin 5 mg/kg, saline/quercetin 25 mg/kg, saline/quercetin 50 mg/kg, saline/simvastatin (0.04 mg/kg), hyperlipidemia, hyperlipidemia/quercetin 5 mg/kg, hyperlipidemia/quercetin 25 mg/kg, hyperlipidemia/quercetin 50 mg/kg, and hyperlipidemia/simvastatin. Animals were pretreated with quercetin for 30 days and hyperlipidemia was subsequently induced by intraperitoneal administration of 500 mg/kg of poloxamer-407. Simvastatin was administered after the induction of hyperlipidemia. Lymphocytes were isolated and E-NTPDase and E-ADA activities were determined. Serum was separated for the cytokines and nucleotide/nucleoside quantification. E-NTPDase and E-ADA activities were increased in lymphocytes from hyperlipidemic rats and pretreatment with quercetin was able to prevent the increase in the activities of these enzymes caused by hyperlipidemia. Hyperlipidemic rats when receiving pretreatment with quercetin and treatment with simvastatin showed decreased levels of ATP and ADP when compared to the untreated hyperlipidemic group. The IFN-gamma and IL-4 cytokines were increased in the hyperlipidemic group when compared with control group, and decreased when hyperlipidemic rats received the pretreatment with quercetin. However, pretreatment with quercetin was able to prevent the alterations caused by hyperlipidemia probably by regulating the inflammatory process. We can suggest that the quercetin is a promising compound to be used as an adjuvant in the treatment of hyperlipidemia. PMID- 29188540 TI - Responses of two kidney bean (Phaseolus vulgaris) cultivars to the combined stress of sulfur deficiency and cadmium toxicity. AB - Plants suffer from combined stress of sulfur deficiency and cadmium toxicity in some agricultural lands. However, little is known about the reaction in plants, such as responses in antioxidant enzymes and non-protein thiol compounds, to such combined stress. Therefore, in this study, four treatments, S-sufficiency (TS Cd), S-deficiency (T-S-Cd), Cd stress (TS+Cd) and combined stress of S-deficiency and Cd stress (T-S+Cd), were set up to investigate (1) the effects of sulfur deficiency or sulfur sufficiency on Cd toxicity to kidney bean cultivar seedlings and the related mechanisms, and (2) the responses of two kidney bean cultivars to combined stress of S-deficiency and Cd-tolerance. The results showed significant increases in hydrogen peroxide (H2O2) and malondialdehyde contents and significant increases in antioxidant enzyme (superoxide dismutase, catalase, peroxidase, and glutathione S-transferase) activities and non-protein thiol compounds (non-protein thiols, reduced glutathione, phytochelatins) synthesis in the plants in TS+Cd and T-S+Cd. On the tissue level, higher proportion of Cd was found to be immobilized/deposited in roots, while on the sub-cell level, higher proportion of Cd was located in cell walls and vacuole fractions with lower in cell organelles. Taken together, the results indicated that Cd detoxification was achieved by the two kidney bean cultivars through antioxidant enzyme activation, non-protein thiol compound synthesis and sub-cellular compartmentalization. In addition, the results indicated that sufficient S supply helped to relieve Cd toxicity, which is of special significance for remediation or utilization of Cd contaminated soils as S is a plant essential nutrient. PMID- 29188541 TI - A Simple Approach for Synthesizing of Fluorescent Carbon Quantum Dots from Tofu Wastewater. AB - We present an investigation on carbon quantum dots (CQDs) synthesized from wastewater induced during the production of tofu. We find that tofu wastewater is a good source of raw material in making fluorescent CQDs. The corresponding CQDs can be fabricated simply via hydrothermal reaction to carbonize the organic matter in the yellow serofluid of tofu wastewater. Two sorts of CQDs can be obtained within the deionized water and NaOH solution, respectively, where the CQDs in water (NaOH solution) can emit blue (green) light under the UV irradiation. It is found from X-ray photoelectron spectroscopy (XPS) that the basic difference between these two sorts of CQDs is the contents of C-O and C=O bonds on the surface of the CQDs. This difference can cause different features of the photoluminescence (PL) spectra of the CQDs. On the basis of the obtained results from the XPS and PL measurements, we propose a mechanism in understanding and explaining the photon-induced light emission from CQDs. This study is relevant to the fabrication and application of fluorescent CQDs as, e.g., light display materials. PMID- 29188542 TI - Wet Beriberi Associated with Hikikomori Syndrome. AB - Wet beriberi, characterized by high cardiac output with predominantly right-sided heart failure and lactic acidosis, is a disease caused by thiamine deficiency, and is rarely seen in modern society. However, patients with social withdrawal syndrome, also known as hikikomori syndrome, may be a new population at risk of thiamine deficiency. Hikikomori syndrome, first recognized in Japan, is becoming a worldwide issue. A 39-year-old Japanese patient was brought to our hospital, with a 3-week history of progressive shortness of breath and generalized edema. The patient had right-sided high-output heart failure, lactic acidosis, and Wernicke-Korsakoff syndrome. Because of his history of social isolation, we diagnosed hikikomori syndrome according to the Japanese government's definition, which is as follows: lifestyle centered at home; no interest or willingness to attend school or work; persistence of symptoms beyond 6 months; and exclusion of other psychiatric and developmental disorders. Considering his diagnosis of hikikomori syndrome and social isolation, we suspected malnutrition, particularly thiamine deficiency, and successfully treated him. Clinicians should be aware of the potential risk of thiamine deficiency associated with hikikomori syndrome and initiate thiamine replacement in cases of high-output heart failure associated with lactic acidosis.

PMID- 29188546 TI - The Treachery Trope: Anti-Semitism as Indicative of a Psycho-Spiritual Disease Associated with the Betrayal of Cultural Ideals and of the Self. AB - The study seeks to place anti-semitism in a wider context by exploring the dynamics of betrayal-a designation often attributed to Jews, but also attributed to many victimized groups who are also deemed to be treacherous. The study argues that what lies at the heart of this practice is the betrayal (on the part of the victimizers) of ideological or personal principles that have not been realized. Instead of taking responsibility for this painful failure, those who have betrayed their principles project their treachery onto a set of victims who are accordingly punished as the 'true' embodiments of treachery. In view of this, cultural and personal health can only be improved if there is a greater consciousness of this psycho-spiritual dynamic; and, as the study suggests, principles associated with enlightenment may be brought to bear against this harmful affliction, which I have named the treachery rope. PMID- 29188545 TI - Historical Legacies, Social Capital, and Women's Decision-Making Power: Religion and Child Nutrition in Mozambique. AB - In sub-Saharan settings, parental religion may have important implications for children's health and well-being. Using survey data from rural Mozambique, we examine the relationship between women's religion and the likelihood of their children being chronically malnourished (stunted). Multivariate analyses show that children of religiously affiliated women are significantly less likely to be stunted than children of non-affiliated women. We also find a strong advantage of mainline Protestants, especially compared to members of Pentecostal-type denominations, net of other factors. We relate this advantage to two historically rooted characteristics of mainline Protestantism: its connections to the public health sector and higher levels of women's autonomy that it fosters. PMID- 29188544 TI - Keystrokes, Mouse Clicks, and Gazing at the Computer: How Physician Interaction with the EHR Affects Patient Participation. AB - BACKGROUND: Evidence is mixed regarding how physicians' use of the electronic health record (EHR) affects communication in medical encounters. OBJECTIVE: To investigate whether the different ways physicians interact with the computer (mouse clicks, key strokes, and gaze) vary in their effects on patient participation in the consultation, physicians' efforts to facilitate patient involvement, and silence. DESIGN: Cross-sectional, observational study of video and event recordings of primary care and specialty consultations. PARTICIPANTS: Thirty-two physicians and 217 patients. MAIN MEASURES: Predictor variables included measures of physician interaction with the EHR (mouse clicks, key strokes, gaze). Outcome measures included active patient participation (asking questions, stating preferences, expressing concerns), physician facilitation of patient involvement (partnership-building and supportive talk), and silence. KEY RESULTS: Patients were less active participants in consultations in which physicians engaged in more keyboard activity (b = -0.002, SE = 0.001, p = 0.02). More physician gaze at the computer was associated with more silence in the encounter (b = 0.21, SE = 0.09, p = 0.02). Physicians' facilitative communication, which predicted more active patient participation (b = 0.65, SE = 0.14, p < 0.001), was not related to EHR activity measures. CONCLUSIONS: Patients may be more reluctant to actively participate in medical encounters when physicians are more physically engaged with the computer (e.g., keyboard activity) than when their behavior is less demonstrative (e.g., gazing at EHR). Using easy to deploy communication tactics (e.g., asking about a patient's thoughts and concerns, social conversation) while working on the computer can help physicians engage patients as well as maintain conversational flow. PMID- 29188547 TI - Humor as Wisdom for Reframing Life. AB - Human beings inevitably experience anxiety but attempt to avoid facing it through various forms of self-deception. This avoidance can lead to pathological symptoms. Young and middle-aged adults may be especially susceptible to suffering from anxiety because they are often single-mindedly pursuing means of achieving security. For these and others who fail to embrace life with warm enthusiasm, humor can serve to alleviate stress. This article views humor as a characteristic disposition of older adults-their humor signifying a sense of integrity and wisdom that often accompanies the aging process. Humor binds together feelings of despair and joy and contributes to a faithful reframing of faith and life. This article proposes that individuals acquire humor by perceiving the world as if on a journey to an exotic new place, seeing with new eyes even the most mundane of everyday objects and events. This capacity to perceive beauty in the ordinary world reflects a wisdom of older adults potentially available even to the young.

AB - Spiritist Hospital Chaplaincy in Brazil has been growing significantly in recent years, with the implementation of new services through the work of Spiritist Medical Associations (SMAs) in different regions of the country. This article describes the importance of historical interconnections from the advent of spiritism in the world and its introduction in Brazil to the emergence of Spiritist Hospital Chaplaincy in our country and presents the documented experience over 5 years of spiritist chaplain care, in the period from 2012 to 2016, guided by the SMA of Piracicaba at the Unimed Hospital of Piracicaba (Sao Paulo). We documented 41,914 visits to 13,983 inpatients and an analysis of these records allowed us to reflect on the importance of this service and confirm its expansion and acceptance by different contemporary religious beliefs. PMID- 29188549 TI - Racial and Ethnic Differences in the Utilization of Prayer and Clergy Counseling by Infertile US Women Desiring Pregnancy. AB - Religion can have a significant influence on the experience of infertility. However, it is unclear how many US women turn to religion when facing infertility. Here, we examine the utilization of prayer and clergy counsel among a nationally representative sample of 1062 infertile US women. Prayer was used by 74.8% of the participants, and clergy counsel was the most common formal support system utilized. Both prayer and clergy counsel were significantly more common among black and Hispanic women. Healthcare providers should acknowledge the spiritual needs of their infertile patients and ally with clergy when possible to provide maximally effective care. PMID- 29188550 TI - UDP-induced relaxation is enhanced in aorta from female obese Otsuka Long-Evans Tokushima Fatty rats. AB - Uridine 5'-diphosphate (UDP) plays an important role in controlling vascular tone; however, UDP-mediated response in metabolic syndromes, including obesity and type 2 diabetes in females, remains unclear. In this study, we investigated UDP-mediated response in the aorta of female obese Otsuka Long-Evans Tokushima Fatty (OLETF) rats and control Long-Evans Tokushima Otsuka (LETO) rats. In OLETF rat aortas precontracted by phenylephrine (PE) (vs. LETO), (1) UDP-induced relaxation was increased, whereas acetylcholine (ACh)-induced relaxation was decreased; (2) no UDP- or ACh-induced relaxations were observed in endothelial denudation, whereas UDP-induced small contraction was observed; and (3) NG-nitro L-arginine [L-NNA, a nitric oxide (NO) synthase inhibitor] eliminated UDP-induced relaxation and small contraction, whereas caused contrasting responses by ACh, including slight relaxations (LETO) and contractions (OLETF). Indomethacin, a cyclooxygenase inhibitor, eliminated the difference in UDP- and ACh-induced relaxations between the groups by increased UDP-induced relaxation in the LETO group and increased ACh-induced relaxation in the OLETF group. MRS2578, a P2Y6 receptor antagonist, eliminated the difference in UDP-induced relaxations between the groups by decreasing UDP-induced relaxation in the OLETF group. MRS2578 had no effect on UDP-induced contraction in endothelium-denuded aortas. Therefore, these findings demonstrate opposite trends of relaxations by UDP and ACh in OLETF and LETO rat aortas. These differences may be attributed to the imbalance between NO and vasoconstrictor prostanoids upon stimulations. Increased UDP-induced relaxation in OLETF rat aorta may be caused by the activation of endothelial MRS2578-sensitive P2Y6 receptor. PMID- 29188551 TI - Molecular Characterization of FMR1 Gene by TP-PCR in Women of Reproductive Age and Women with Premature Ovarian Insufficiency. AB - BACKGROUND: Fragile X syndrome is caused by CGG repeat expansion mutation in the FMR1 gene. Normal alleles have 5-44 CGG repeats with AGG interruptions. The expanded gray zone (GZ) (45-54 repeats) and premutation (PM) (55-200 repeats) alleles are often uninterrupted and are unstably inherited in subsequent generations. The prevalence of PM and GZ carriers is high in the female population, at 1/66 and 1/113, respectively, and PM is associated with fertility problems in 20% of cases. OBJECTIVE: Our objective was to molecularly characterize CGG repeats and AGG interruption sequences in the FMR1 gene in women of reproductive age and in women with premature ovarian insufficiency (POI). MATERIALS AND METHODS: We conducted molecular analysis of the FMR1 gene from 300 women of reproductive age and 140 women with POI using triplet primed-polymerase chain reaction. This enabled us to identify carriers and to document CGG repeat size and the AGG interruption pattern. RESULTS: In women of reproductive age, 1.7% were GZ carriers and 0.3% were PM carriers; in women with POI, 3.6% were GZ carriers and 2.14% were PM carriers. The frequency of GZ and PM carriers did not significantly differ between the cohorts (Fisher's exact test: p < 2.23 for GZ vs. control and p < 0.101 for PM vs. control). Carriers received genetic counselling; family screening identified an additional seven carriers. CONCLUSION: We documented preliminary data on the prevalence of GZ and PM carriers among the studied cohorts. The identification of PM carriers among women with POI serves a dual purpose of recognizing a cause for ovarian dysfunction and enabling genetic counselling, which will help carriers when making reproductive decisions. PMID- 29188552 TI - Intrahepatic subcapsular biloma after endoscopic retrograde cholangiopancreatography treated by endoscopic biliary drainage. AB - Several major complications from endoscopic retrograde cholangiopancreatography (ERCP), including pancreatitis, cholangitis, and hemorrhage have been discussed in detail; however, a few uncommon but severe complications have been reported. We encountered an unusual case of post-ERCP intrahepatic subcapsular biloma. An 89-year-old woman with a 25-mm mass located at the hepatic hilum, suggestive of cholangiocarcinoma, underwent ERCP which demonstrated complete stricture of the common hepatic duct. Subsequently, two plastic stents were placed from the common bile duct to the right and left intrahepatic branches. On day 3, serum inflammatory markers were elevated and computed tomography revealed a large subcapsular fusiform fluid collection in the right liver, consistent with biloma. On day 6, the biloma ruptured and 500 ml of biliary ascites were removed. On day 8, endoscopic nasobiliary drainage via the right intrahepatic branch was performed because of recurrence of biliary ascites. After the procedure, 150 ml of bile was collected through the drain every day and no ascites recurred. We believe that minor injury to the right intrahepatic bile duct due to guidewire manipulation caused the biloma. Biloma may become apparent several days after ERCP, and endoscopic biliary drainage placement adjacent to the bile duct rupture site can stop bile leakage. PMID- 29188553 TI - Sociodemographic Factors Mediate Race and Ethnicity-associated Childhood Asthma Health Disparities: a Longitudinal Analysis. AB - BACKGROUND: Race and ethnicity-based disparities in childhood asthma are well established. We characterized the longitudinal effects associated with being African-American/Black or Hispanic/Latino on a range of asthma outcomes, and the extent to which sociodemographic factors, caregiver health literacy, education level, and asthma knowledge mediate these associations. METHODS: Children ages 8 15 and their caregivers (n = 544) in the Chicago Initiative to Raise Asthma Health Equity (CHIRAH) cohort completed interviews every 3 months for 1.5 years. Health literacy was measured with the Rapid Estimate of Adult Literacy in Medicine (REALM). Other covariates include sex, age, education level, income, smoke exposure, asthma duration, employment status, and insurance status. We conducted a series of models to evaluate these factors as mediators of the relationship between race/ethnicity and (1) asthma knowledge, (2) asthma-related quality of life, (3) asthma severity, and (4) asthma control based on NAEPP/EPR-3 2007 guidelines. RESULTS: African-American race and Hispanic/Latino ethnicity were significantly associated with all outcomes when compared to Whites. Adjusting for sociodemographic factors resulted in the most significant mediation of racial/ethnic disparities in all outcomes. Health literacy was a partial mediator of race/ethnic disparities in asthma knowledge and asthma-related quality of life. Asthma knowledge remained significantly associated with race and ethnicity, and race remained associated with asthma-related quality of life. CONCLUSIONS: African-American race and Hispanic/Latino ethnicity are significantly associated with worse asthma compared to Whites in longitudinal analyses. Sociodemographic factors are potent mediators of these disparities, and should be considered when designing interventions to reduce asthma disparities. Health literacy and education level are partial mediators.

PMID- 29188556 TI - Current and Future Challenges in GPCR Drug Discovery. AB - GPCRs play a pervasive physiological role and, in turn, are the leading target class for pharmaceuticals. Beginning with the determination of the structure of rhodopsin, and dramatically accelerating since the reporting of the first ligand mediated GPCR X-ray structures, our understanding of the structural and functional characteristics of these proteins has grown dramatically. Deploying this now rapidly emerging information for drug discovery has already been extensively demonstrated through a watershed of studies appearing in numerous scientific reports. Included in these expositions are areas such as sites and characteristics of ligand to GPCR binding, protein activation, effector bias, allosteric mechanisms, dimerization, polypharmacology and others. Computational chemistry studies are demonstrating an increasing role in capitalizing on the structural studies to further advance our understanding of these proteins as well as to drive drug discovery. Such drug discovery activities range from the design of orthosteric site inhibitors through, for example, allosteric modulators, biased ligands, partial agonists and bitopic ligands. Herein, these topics are outlined through specific examples in the hopes of providing a glimpse of the state of the field. PMID- 29188557 TI - Characterization of Ligand Binding to GPCRs Through Computational Methods. AB - The recent increase in available G protein-coupled receptor structures now contributes decisively to the structure-based ligand design. In this context, computational approaches in combination with medicinal chemistry and pharmacology are extremely helpful. Here, we provide an update on our structure-based computational protocols, used to answer key questions related to GPCR-ligand binding. All combined, these techniques can shed light on ligand binding modes, determine the molecular basis of conformational selection, for agonists and antagonists, as well as of subtype selectivity. To illustrate each of these questions, we will consider examples from existing projects on three families of class A (rhodopsin-like) GPCRs: one small-molecule (nucleotide-like) family, i.e., the adenosine receptors, and two peptide-binding receptors: neuropeptide-Y and angiotensin II receptors. The successful application of the same computational protocols to investigate this diverse group of receptor families gives an idea of the general applicability of our methodology in the characterization of GPCR-ligand binding. PMID- 29188559 TI - A Structural Framework for GPCR Chemogenomics: What's In a Residue Number? AB - The recent surge of crystal structures of G protein-coupled receptors (GPCRs), as well as comprehensive collections of sequence, structural, ligand bioactivity, and mutation data, has enabled the development of integrated chemogenomics workflows for this important target family. This chapter will focus on cross family and cross-class studies of GPCRs that have pinpointed the need for, and the implementation of, a generic numbering scheme for referring to specific structural elements of GPCRs. Sequence- and structure-based numbering schemes for different receptor classes will be introduced and the remaining caveats will be discussed. The use of these numbering schemes has facilitated many chemogenomics studies such as consensus binding site definition, binding site comparison, ligand repurposing (e.g. for orphan receptors), sequence-based pharmacophore generation for homology modeling or virtual screening, and class-wide chemogenomics studies of GPCRs. PMID- 29188558 TI - Breakthrough in GPCR Crystallography and Its Impact on Computer-Aided Drug Design. AB - Recent crystallographic structures of G protein-coupled receptors (GPCRs) have greatly advanced our understanding of the recognition of their diverse agonist and antagonist ligands. We illustrate here how this applies to A2A adenosine receptors (ARs) and to P2Y1 and P2Y12 receptors (P2YRs) for ADP. These X-ray structures have impacted the medicinal chemistry aimed at discovering new ligands for these two receptor families, including receptors that have not yet been crystallized but are closely related to the known structures. In this Chapter, we discuss recent structure-based drug design projects that led to the discovery of: (a) novel A3AR agonists based on a highly rigidified (N)-methanocarba scaffold for the treatment of chronic neuropathic pain and other conditions, (b) fluorescent probes of the ARs and P2Y14R, as chemical tools for structural probing of these GPCRs and for improving assay capabilities, and (c) new more drug-like antagonists of the inflammation-related P2Y14R. We also describe the computationally enabled molecular recognition of positive (for A3AR) and negative (P2Y1R) allosteric modulators that in some cases are shown to be consistent with structure-activity relationship (SAR) data. Thus, computational modeling has become an essential tool for the design of purine receptor ligands. PMID- 29188560 TI - GPCR Homology Model Generation for Lead Optimization. AB - The vast increase of recently solved GPCR X-ray structures forms the basis for GPCR homology modeling to atomistic accuracy. Nowadays, homology models can be employed for GPCR-ligand optimization and have been reported as invaluable tools for drug design in the last few years. Elucidation of the complex GPCR pharmacology and the associated GPCR conformations made clear that different homology models have to be constructed for different activation states of the GPCRs. Therefore, templates have to be chosen accordingly to their sequence homology as well as to their activation state. The subsequent ligand placement is nontrivial, as some recent X-ray structures show very unusual ligand binding sites and solvent involvement, expanding the space of the putative ligand binding site from the generic retinal binding pocket to the whole receptor. In the present study, a workflow is presented starting from the selection of the target sequence, guiding through the GPCR modeling process, and finishing with ligand placement and pose validation. PMID- 29188561 TI - GPCRs: What Can We Learn from Molecular Dynamics Simulations? AB - Advances in the structural biology of G-protein Coupled Receptors have resulted in a significant step forward in our understanding of how this important class of drug targets function at the molecular level. However, it has also become apparent that they are very dynamic molecules, and moreover, that the underlying dynamics is crucial in shaping the response to different ligands. Molecular dynamics simulations can provide unique insight into the dynamic properties of GPCRs in a way that is complementary to many experimental approaches. In this chapter, we describe progress in three distinct areas that are particularly difficult to study with other techniques: atomic level investigation of the conformational changes that occur when moving between the various states that GPCRs can exist in, the pathways that ligands adopt during binding/unbinding events and finally, the influence of lipids on the conformational dynamics of GPCRs. PMID- 29188562 TI - Methods of Exploring Protein-Ligand Interactions to Guide Medicinal Chemistry Efforts. AB - We present a number of techniques to analyze protein-ligand interactions in the context of medicinal chemistry: crystal Contract Preferences, Electrostatic Maps and pharmacophore screening using Huckel Theory. Contact Preferences is a statistical technique to predict hydrophobic and hydrophilic geometry in receptor active sites. Electrostatic Maps use the Poisson-Boltzmann Equation to model solvation effects and are particularly useful for predicting hydrophobic regions. Pharmacophore annotation with Huckel Theory provides finer detail of hydrogen bonding interactions, including CH..O interactions. Applications to AblK:Gleevec and CDK2 virtual screening are presented. PMID- 29188563 TI - Exploring GPCR-Ligand Interactions with the Fragment Molecular Orbital (FMO) Method. AB - The understanding of binding interactions between any protein and a small molecule plays a key role in the rationalization of affinity and selectivity. It is essential for an efficient structure-based drug design (SBDD) process. FMO enables ab initio approaches to be applied to systems that conventional quantum mechanical (QM) methods would find challenging. The key advantage of the Fragment Molecular Orbital Method (FMO) is that it can reveal atomistic details about the individual contributions and chemical nature of each residue and water molecule toward ligand binding which would otherwise be difficult to detect without using QM methods. In this chapter, we demonstrate the typical use of FMO to analyze 19 crystal structures of beta1 and beta2 adrenergic receptors with their corresponding agonists and antagonists. PMID- 29188564 TI - Molecular Basis of Ligand Dissociation from G Protein-Coupled Receptors and Predicting Residence Time. AB - G protein-coupled receptors (GPCRs) are integral membrane proteins and represent the largest class of drug targets. During the past decades progress in structural biology has enabled the crystallographic elucidation of the architecture of these important macromolecules. It also provided atomic-level visualization of ligand receptor interactions, dramatically boosting the impact of structure-based approaches in drug discovery. However, knowledge obtained through crystallography is limited to static structural information. Less information is available showing how a ligand associates with or dissociates from a given receptor, whose importance is in fact increasingly recognized by the drug research community. Owing to recent advances in computer power and algorithms, molecular dynamics stimulations have become feasible that help in analyzing the kinetics of the ligand binding process. Here, we review what is currently known about the dynamics of GPCRs in the context of ligand association and dissociation, as determined through both crystallography and computer simulations. We particularly focus on the molecular basis of ligand dissociation from GPCRs and provide case studies that predict ligand dissociation pathways and residence time.

PMID- 29188566 TI - Methods for Virtual Screening of GPCR Targets: Approaches and Challenges. AB - Virtual screening (VS) has become an integral part of the drug discovery process and is a valuable tool for finding novel chemical starting points for GPCR targets. Ligand-based VS makes use of biochemical data for known, active compounds and has been applied successfully to many diverse GPCRs. Recent progress in GPCR X-ray crystallography has made it possible to incorporate detailed structural information into the VS process. This chapter outlines the latest VS techniques along with examples that highlight successful applications of these methods. Best practices for increasing the likelihood of VS success, as well as ongoing challenges, are also discussed. PMID- 29188567 TI - Approaches for Differentiation and Interconverting GPCR Agonists and Antagonists. AB - Predicting the functional preferences of the ligands was always a highly demanding task, much harder that predicting whether a ligand can bind to the receptor. This is because of significant similarities of agonists, antagonists and inverse agonists which are binding usually in the same binding site of the receptor and only small structural changes can push receptor toward a particular activation state. For G protein-coupled receptors, due to a large progress in crystallization techniques and also in receptor thermal stabilization, it was possible to obtain a large number of high-quality structures of complexes of these receptors with agonists and non-agonists. Additionally, the long-time-scale molecular dynamics simulations revealed how the activation processes of GPCRs can take place. Using both theoretical and experimental knowledge it was possible to employ many clever and sophisticated methods which can help to differentiate agonists and non-agonists, so one can interconvert them in search of the optimal drug. PMID- 29188568 TI - Opportunities and Challenges in the Discovery of Allosteric Modulators of GPCRs. AB - From the pharmacological point of view, allosteric modulators may present numerous advantages over orthosteric ligands. Growing availability of novel tools and experimental data provides a tempting opportunity to apply computational methods to improve known modulators and design novel ones. However, recent progress in understanding of complexity of allostery increases awareness of problems involved in design of modulators with desired properties. Deeper insight into phenomena such as probe dependence, altering signaling bias with minor changes in ligand structure, as well as influence of subtle endogenous allosteric factors turns out to be fundamental. These effects make the design of a modulator with precise pharmacological outcome a very challenging task, and need to be taken into consideration throughout the design process. In this chapter, we focus on nuances of targeting GPCR allosteric sites in computational drug design efforts, in particular with application of docking, virtual screening, and molecular dynamics. PMID- 29188569 TI - Challenges and Opportunities in Drug Discovery of Biased Ligands. AB - The observation of biased agonism in G protein-coupled receptors (GPCRs) has provided new approaches for the development of more efficacious and safer drugs. However, in order to rationally design biased drugs, one must understand the molecular basis of this phenomenon. Computational approaches can help in exploring the conformational universe of GPCRs and detecting conformational states with relevance for distinct functional outcomes. This information is extremely valuable for the development of new therapeutic agents that promote desired conformational receptor states and responses while avoiding the ones leading to undesired side-effects.This book chapter intends to introduce the reader to powerful computational approaches for sampling the conformational space of these receptors, focusing first on molecular dynamics and the analysis of the produced data through methods such as dimensionality reduction, Markov State Models and adaptive sampling. Then, we show how to seek for compounds that target distinct conformational states via docking and virtual screening. In addition, we describe how to detect receptor-ligand interactions that drive signaling bias and comment current challenges and opportunities of presented methods. PMID- 29188570 TI - Synergistic Use of GPCR Modeling and SDM Experiments to Understand Ligand Binding. AB - There is a substantial amount of historical ligand binding data available from site-directed mutagenesis (SDM) studies of many different GPCR subtypes. This information was generated prior to the wave of GPCR crystal structure, in an effort to understand ligand binding with a view to drug discovery. Concerted efforts to determine the atomic structure of GPCRs have proven extremely successful and there are now more than 80 GPCR crystal structure in the PDB database, many of which have been obtained in the presence of receptor ligands and associated G proteins. These structural data enable the generation of computational model structures for all GPCRs, including those for which crystal structures do not yet exist. The power of these models in designing novel ligands, especially those with improved residence times, and for better understanding receptor function can be enhanced tremendously by combining them synergistically with historic SDM ligand binding data. Here, we describe a protocol by which historic SDM binding data and receptor models may be used together to identify novel key residues for mutagenesis studies. PMID- 29188571 TI - Computational Support of Medicinal Chemistry in Industrial Settings. AB - The practice of computational chemistry in an industrial setting poses unique opportunities and challenges. Industrial computational chemists must manage large amounts of data, master modeling software, write scripts to perform custom calculations, and stay abreast of scientific advances in the field. Just as importantly, because computational chemists are full partners in the drug discovery effort at companies, in order to influence and streamline the drug discovery process, they must communicate effectively with medicinal chemists and other scientists to deliver results of their calculations in a timely fashion. The skills necessary to play this role require education that emphasizes a combination of chemistry, programming, and communication skills. Professors are encouraged to incorporate such training in their curriculum. PMID- 29188573 TI - Ligand-Based Methods in GPCR Computer-Aided Drug Design.

PMID- 29188572 TI - Investigating Small-Molecule Ligand Binding to G Protein-Coupled Receptors with Biased or Unbiased Molecular Dynamics Simulations. AB - An increasing number of G protein-coupled receptor (GPCR) crystal structures provide important-albeit static-pictures of how small molecules or peptides interact with their receptors. These high-resolution structures represent a tremendous opportunity to apply molecular dynamics (MD) simulations to capture atomic-level dynamical information that is not easy to obtain experimentally. Understanding ligand binding and unbinding processes, as well as the related responses of the receptor, is crucial to the design of better drugs targeting GPCRs. Here, we discuss possible ways to study the dynamics involved in the binding of small molecules to GPCRs, using long timescale MD simulations or metadynamics-based approaches. PMID- 29188574 TI - Computational Methods Used in Hit-to-Lead and Lead Optimization Stages of Structure-Based Drug Discovery. AB - GPCR modeling approaches are widely used in the hit-to-lead (H2L) and lead optimization (LO) stages of drug discovery. The aims of these modeling approaches are to predict the 3D structures of the receptor-ligand complexes, to explore the key interactions between the receptor and the ligand and to utilize these insights in the design of new molecules with improved binding, selectivity or other pharmacological properties. In this book chapter, we present a brief survey of key computational approaches integrated with hierarchical GPCR modeling protocol (HGMP) used in hit-to-lead (H2L) and in lead optimization (LO) stages of structure-based drug discovery (SBDD). We outline the differences in modeling strategies used in H2L and LO of SBDD and illustrate how these tools have been applied in three drug discovery projects. PMID- 29188575 TI - Cheminformatics in the Service of GPCR Drug Discovery. AB - Cheminformatics is a broad discipline covering a wide range of computational approaches, including the characterization of molecular similarity, pattern recognition, and predictive modeling. The unifying theme that these apparently disparate methods have in common is the aim of extracting useable information from the increasing amounts of data that are associated with contemporary drug discovery projects. Both proprietary and publically available data can be exploited to help inform and improve the process of developing novel therapeutic molecules targeting the GPCR family of proteins. PMID- 29188576 TI - Modeling and Deorphanization of Orphan GPCRs. AB - Despite tremendous efforts, approximately 120 GPCRs remain orphan. Their physiological functions and their potential roles in diseases are poorly understood. Orphan GPCRs are extremely important because they may provide novel therapeutic targets for unmet medical needs. As a complement to experimental approaches, molecular modeling and virtual screening are efficient techniques to discover synthetic surrogate ligands which can help to elucidate the role of oGPCRs. Constitutively activated mutants and recently published active structures of GPCRs provide stimulating opportunities for building active molecular models for oGPCRs and identifying activators using virtual screening of compound libraries. We describe the molecular modeling and virtual screening process we have applied in the discovery of surrogate ligands, and provide examples for CCKA, a simulated oGPCR, and for two oGPCRs, GPR52 and GPR34.

Therefore, we systematically reviewed the effect of resistance training (RT) alone or combined with multimodal exercise intervention on muscle hypertrophy, maximal strength, power output, functional performance, and falls incidence in physically frail elderly. METHODS: MEDLINE, Cochrane CENTRAL, PEDro, and SPORTDiscus databases were searched from 2005 to 2017. Studies must have mentioned the effects of RT (i.e., included or not in multimodal training) on at least one of the following parameters: muscle mass, muscle strength, muscle power, functional capacity, and risk of falls in frail elderly. RESULTS: The initial search identified 371 studies and 16 were used for qualitative analysis for describing the effect of strength training performed alone or in a multimodal exercise intervention. We observed that RT alone or in a multimodal training may induce increases of 6.6-37% in maximal strength; 3.4-7.5% in muscle mass, 8.2% in muscle power, 4.7-58.1% in functional capacity and risk of falls, although some studies did not show enhancements. CONCLUSION: Frequency of 1-6 sessions per week, training volume of 1-3 sets of 6-15 repetitions and intensity of 30-70%1-RM promoted significant enhancements on muscle strength, muscle power, and functional outcomes. Therefore, in agreement with previous studies, we suggest that supervised and controlled RT represents an effective intervention in frailty treatment. PMID- 29188578 TI - Trajectory and variability characterization of the Montreal cognitive assessment in older adults. AB - BACKGROUND: The Montreal cognitive assessment (MoCA) has become one of the most widely used cognitive screening instruments since its initial publication. To date, only a handful of studies have explored longitudinal characteristics of the MoCA. AIM: The aim of this study is to characterize the trajectory of MoCA performance across a broad age continuum of older adults. METHODS: Data from 467 cognitively normal participants were used in this analysis. The sample was grouped into four strata based on the participants' age at baseline (60-69, 70 79, 80-89, and 90-99). Mixed model repeated measures (MMRM) analysis and mixed effects spline models were used to characterize the trajectory of MoCA scores in each age stratum and in the entire sample. Intrasubject standard deviation (ISD) was used to characterize the natural variability of individual MoCA performance over time. RESULTS: The ISD values for each of the age strata indicated that year to-year individual variation on the MoCA ranged from zero to three points. MMRM analysis showed that the 60-69 stratum remained relatively stable over time while the 70-79 and 80-89 strata both showed notable decline relative to baseline performance. The mixed-effects spline model showed that MoCA performance declines linearly across the older adult age span. DISCUSSION: Among cognitively normal older adults MoCA performance remains relatively stable over time, however across the older adult age-span MoCA performance declines in a linear fashion. These results will help clinicians better understand the normal course of MoCA change in older adults while researchers may use these results to inform sample size estimates for intervention studies. CONCLUSION: This study provides an enhanced view of the MoCA's intraindividual trajectory in normal elderly aged 60 and older. PMID- 29188579 TI - Sauna bathing, health, and quality of life among octogenarian men: the Helsinki Businessmen Study. AB - BACKGROUND AND AIM: Sauna-type bathing has increased worldwide, and it has been related to both harmful and beneficial effects. There are few studies of bathing in sauna in very old age. METHODS: The series consists of 524 mostly home-living survivors of the Helsinki Businessmen Study (HBS, mean age 86 years, range 80 95), who in 2015 responded to a questionnaire survey about lifestyle (including sauna bathing), prevalent diseases, and health-related quality of life (HRQoL, RAND-36). RESULTS: Of the men 57.6% (n = 302) reported all-year round and 17.6% (n = 92) part-year sauna bathing. Sauna was currently used mostly once a week, but 10% bathed more than twice a week. Median time in the hot room was 15 min at 80 degrees C. Among 45.7% of the men, the habit had decreased with ageing, and 130 (24.8%) did not attend sauna. However, 92.2% of the latter had discontinued an earlier habit, respective proportions 20.7% and 75.0% among all-year and part year users. Overall, reasons for decreased sauna bathing were nonspecific or related to mobility problems or diverse health reasons (n = 63). The most frequent motivations for sauna were relaxation and hygienic reasons. Of the RAND 36 domains physical function, vitality, social functioning, and general health were significantly better among sauna users than non-users. These differences partly remained after adjusting for prevalent diseases and mobility-disability. CONCLUSIONS: Regular sauna bathing was common among octogenarian men and was associated with better HRQoL. However, reverse causality must be taken into account in this cross-sectional study. The bathing habit seemed to be prudent and had decreased in almost half of the cohort. PMID- 29188580 TI - 10-year complete remission in a Philadelphia chromosome-positive acute lymphoblastic leukemia patient using imatinib without high-intensity chemotherapy or allogeneic stem cell transplantation. AB - The outcome of Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph ALL) has improved with the use of tyrosine kinase inhibitors, such as imatinib and dasatinib. We report a 63-year-old woman with Ph-ALL who maintained complete remission for 10 years using imatinib without high-intensity chemotherapy or allogeneic stem cell transplantation. She underwent induction therapy with imatinib plus prednisolone and achieved complete remission by day 53. Imatinib was continued until 103 months, when it was stopped in response to renal dysfunction; however, the patient continued to exhibit molecular remission at 120 months. This is the first report in the literature describing a patient with Ph ALL who achieved remission for more than 10 years after treatment only with imatinib.

PMID- 29188582 TI - A low birth weight infant with no malformations delivered by a primary immune thrombocytopenia patient treated with eltrombopag. AB - Primary immune thrombocytopenia (ITP) is defined by a low platelet count secondary to antibody-mediated platelet destruction or reductions in platelet production. Although eltrombopag is a thrombopoietin receptor agonist that increases platelet production in refractory or relapsed ITP, the influence on pregnancy is limited. We present the case of a pregnant 25-year-old ITP patient referred to our hospital with a history of two induced abortions. After eradication of Helicobacter pylori and with oral prednisolone at 8 mg/day, platelet count remained below 10,000/ul. Because she declined splenectomy, eltrombopag was initiated at 12.5 mg/day. Afterward, platelet count was maintained at over 50,000/ul. Twenty-one months later, pregnancy became apparent. She continued treatment, and cesarean section was performed at 37 weeks of gestation after administration of intravenous immunoglobulin, platelet transfusions, and steroids. The baby weighed only 1670 g but showed no malformations, and platelet count at birth was 416,000/ul. Studies of eltrombopag in pregnancy have not been reported. A case with administration of eltrombopag from the last trimester of pregnancy that resulted in low birth weight has been reported. Embryo lethality and reduced fetal weights have been reported from animal experiments. Further investigation about the relationship between low birth weight deliveries and eltrombopag is necessary. PMID- 29188583 TI - Infusions of Epstein-Barr virus-specific cytotoxic T lymphocytes as post remission therapy in high-risk post-transplant lymphoproliferative disorder patients: report of two cases. AB - Conventional therapeutic approaches to post-transplant lymphoproliferative disorder (PTLD) occurring after solid-organ transplantation have shown only limited success in achieving durable response. Key factors driving the pathogenesis of PTLD include Epstein-Barr virus (EBV) reactivation and impaired immune surveillance due to prolonged immune suppression. Thus, EBV-specific cytotoxic T lymphocytes (EBV-CTLs) have emerged as an alternative therapeutic approach for the treatment of EBV-associated PTLD by enhancing EBV-specific immunity. We evaluated the safety and efficacy of EBV latent membrane proteins (LMP)-1- and 2-specific CTLs in two PTLD patients at high risk for relapse. Following diagnosis, patients were initially treated with a combination of chemotherapy and/or radiotherapy. Patients then received a total of eight doses of 2 * 107 EBV-CTLs/m2. Following initial therapy, both patients achieved complete remission confirmed by FDG-PET/CT imaging. Post-remission therapy using adoptive transfer of EBV-CTLs was safe without immediate or late toxicities. Infusion of EBV-CTLs led to an overall reduction in plasma EBV levels in the peripheral blood, which was associated with long-term remission of both patients during a follow-up of more than 65 months. Further prospective studies with larger number of patients will be needed to confirm the role of EBV-CTLs as post remission therapy in high-risk PTLD. PMID- 29188584 TI - Enhancing the Validity of a Quality of Life Measure for Autistic People. AB - Accurate measurement of quality of life (QoL) is important for evaluation of autism services and trials of interventions. We undertook psychometric validation of the World Health Organisation measure-WHOQoL-BREF, examined construct validity of the WHO Disabilities module and developed nine additional autism-specific items (ASQoL) from extensive consultation with the autism community. The sample of 309 autistic people was recruited from the Adult Autism Spectrum Cohort-UK. The WHOQoL-BREF had good psychometric properties, including criterion, convergent, divergent and discriminant validity. The WHO Disabilities module showed adequate construct validity and reliability. The ASQoL items form a unitary factor of QoL, with one global item. Future studies can use the WHO measures alongside the ASQoL items to measure QoL of autistic people. PMID- 29188585 TI - Brief Report: How Accurate is Teacher Report of Autism Symptoms Compared to Parent Report? AB - The Checklist for Autism Spectrum Disorder (CASD) completed by a psychologist (following standardized procedures integrating parent interview data, teacher report, and clinical observations) was compared with the CASD completed independently by mothers and teachers in 168 children with ASD and 40 with ADHD (1-12 years). The 30 CASD autism symptoms are scored as present or absent. Using mother scores 36% of children with ASD scored below the autism diagnostic cutoff, and 75% scored below the cutoff based on teacher scores. Many symptoms deemed present by the psychologist were not reported on the mother and teacher CASD. Mother-teacher correlations indicated little correspondence. Mother and teacher CASD scores should never be used alone. Diagnostic instruments must be administered following standardized procedures. PMID- 29188586 TI - In Search of Culturally Appropriate Autism Interventions: Perspectives of Latino Caregivers. AB - Most evidence-based autism spectrum disorder (ASD) interventions are tested with primarily White, mid-upper class, English-speaking populations, despite the increase in Latino children with ASD in early intervention programs throughout the United States. Unfortunately, interventions that are incongruent with a target population's culture may be relatively ineffective. This mixed-methods study explored how culturally appropriate, feasible, and acceptable Latino caregivers perceived intervention models, strategies, and targets. Survey data were compared for 28 Latino and 27 non-Latino White parents of young children with ASD. Further, 20 Latino caregivers participated in focus groups to describe their challenges, perspectives and preferences for intervention strategies and models, and unmet needs from providers. These findings underscore the need for culturally modified interventions for Latino children and families. PMID- 29188587 TI - Focus on the Social Aspect of Autism. AB - Autism spectrum disorder (ASD) describes a set of neurodevelopmental disorders. Despite extensive ASD research lasting more than 60 years, its causes are still unknown. Without indicating the etiology, its development cannot be stopped. Over the years, both the definition and diagnostic criteria have developed. The number of ASD incidence is rising. The economical aspect should also be highlighted. This disorder presents particular challenges to affected children, their parents and physicians. The research of ASD, physician activities, policy making and raising the level of awareness must be coordinated. Special attention should be paid to the problem among adults with ASD. PMID- 29188588 TI - Sibling Relationships: Parent-Child Agreement and Contributions of Siblings With and Without ASD. AB - Research on the experiences of siblings of individuals with ASD and the quality of their sibling relationships has yielded mixed results. The present study examined the significance of parent- versus child-report of both positive and negative behaviors exhibited by siblings and their brothers and sisters with ASD within sibling dyads. Findings indicated that siblings were more positive in their assessment of the sibling relationship than were their parents. Siblings exhibited more positive behaviors within the sibling relationship than did their brothers and sisters with ASD, and were recipients of aggression. These findings are consistent with prior research suggesting that siblings tend to take on a caretaking role, and point to important targets for intervention. PMID- 29188589 TI - Psychometric Properties of Spanish Adaptation of the PDD-MRS Scale in Adults with Intellectual Developmental Disorders: The EVTEA-DI Scale. AB - Strategies for the early detection of autism spectrum disorders (ASD) in people with intellectual developmental disorder (IDD) are urgently needed, but few specific tools have been developed. The present study examines the psychometric properties of the EVTEA-DI, a Spanish adaptation of the PDD-MRS, in a large randomized sample of 979 adults with IDD. Factorial solution analysis suggested a three-factor solution (stereotyped behavior, communication, and social behavior). The EVTEA-DI showed good reliability and convergent validity when compared to the Childhood Autism Rating Scale. Discriminative validity analysis resulted in an acceptable global sensitivity of 70% and a high specificity of 90%. The EVTEA-DI proved to be a valid screening tool in ASD assessment of the adult Spanish population with IDD. PMID- 29188590 TI - Characteristics of Cobalt-Related Cardiomyopathy in Metal Hip Implant Patients: An Evaluation of 15 Published Reports. AB - Over 300,000 hip replacements occurred in the USA in 2010, and the frequency is likely increasing annually. Blood Cobalt (Co) concentrations in patients with well-functioning cobalt-chromium (Co-Cr) hip implants are usually elevated above background concentrations relative to the general population. Excessive Co exposure, in rare cases, can result in cardiomyopathy. The purpose of this review was to identify cases of cardiomyopathy in metal-containing hip implant patients and to evaluate the possible cause of each patient's cardiomyopathy. We evaluated 15 cases published between 2009 and 2016, and, based on a review of the preexisting risk factors, blood Co concentrations, and histopathological information published for each patient, they were stratified into one of four categories regarding the association between Co exposure and the development of cardiomyopathy: (1) Co was causal (five cases); (2) Co was contributory (two cases); (3) Co was possibly contributory (six cases); and (4) Co was non-causal (two cases). In all 15 cases, blood Co concentrations (14-6521 MUg/L) were elevated beyond levels associated with the majority of metal-containing implant patients (0.1-10 MUg/L), and, in many cases, there was evidence of a malfunctioning implant. The data indicate that individuals with well-functioning implants, even those with preexisting risk factors, are at no risk of developing cardiac effects. We conclude that blood Co measurements are informative, but should be interpreted with caution, and in context of other factors evaluated in this analysis. The mere presence of elevated Co is not sufficient to indicate causation for a patient's cardiomyopathy. PMID- 29188591 TI - Contact Dermatitis after Prescription of an Ophthalmic Ointment Containing Fradiomycin Sulfate: A Retrospective Database Study Using Japanese Health Insurance Claims Data. AB - BACKGROUND: Topical ointments containing fradiomycin sulfate, such as fradiomycin sulfate/methylprednisolone (F/M) and fradiomycin sulfate/betamethasone sodium phosphate (F/B), are known to cause allergic contact dermatitis (CD) in some patients, especially when used for the periocular region. F/M is commonly prescribed to patients for various conditions; however, there are no reports with respect to the incidence of CD caused by F/M in actual practice. OBJECTIVE: The aim was to investigate the incidence of CD using a data-based retrospective cohort study. METHODS: Using a Japanese health insurance claims database [MinaCare Co. Ltd. healthcare database (MinaCare HDB)], a comparative assessment was conducted of F/M and another combination drug (F/B) and two single-drug treatments (ophthalmic ointments with either an antibiotic or a steroid). The total data set consisted of 1,176,082 individuals in the MinaCare HDB, with 54,016 having received prescriptions for one of the four investigational drug regimens. RESULTS: Overall, the incidences of CD were similar in three of the four groups in this study (F/M 0.091; F/B 0.092; steroids 0.102), while being lower in the fourth group (antibiotics 0.060). Even after confirmation of a diagnosis of CD, prescriptions for the investigational drugs were repeatedly filled for some patients. CONCLUSION: This study demonstrated that there was no clear difference in the incidence of CD after filling prescriptions for F/M, F/B, and ophthalmic ointment containing a steroid, while the incidence with antibiotics was lower by 0.03-0.04 compared with the other groups. Considering the observation that the investigational drugs were repeatedly prescribed even after the diagnosis of CD, it is critical that the risk of CD with these prescribed topical ointments is better understood by primary care physicians in order to take appropriate countermeasures. PMID- 29188593 TI - Recreational physical activity and survival in African-American women with ovarian cancer. AB - PURPOSE: While recreational physical activity (RPA) has been associated with reduced mortality in breast, colorectal, and prostate cancers, evidence for epithelial ovarian cancer (EOC) is limited. Most EOC studies have been in predominantly white populations, although inactivity is more prevalent and survival is poorer among African-American (AA) women. We examined RPA before and after EOC diagnosis and associations with survival among AA women. METHODS: We analyzed data from 264 EOC survivors enrolled in a population-based, case-control study who completed surveys that included questions about pre- and post-diagnosis RPA. Data were collected on RPA frequency, intensity, and duration before diagnosis and approximately 1 year after the baseline interview. We calculated metabolic equivalent of task (MET)-hours/week for pre- and post-diagnosis RPA, and evaluated associations with risk of mortality using Cox proportional hazards models. RESULTS: RPA before diagnosis was not associated with mortality. Hazard ratios (HRs) for post-diagnosis RPA were < 1.0 but not statistically significant after adjustment for covariates; HRs were 0.94 (95% CI 0.58, 1.54) for > 0-9 MET hours/week and 0.53 (95% CI 0.21, 1.35) for > 9 MET-hours/week. CONCLUSIONS: Our results suggest that RPA may be inversely associated with mortality among AA women with ovarian cancer, although it is possible that the present study was underpowered to detect an association. There is a clear need for more studies of RPA after diagnosis in EOC survivors with attention to potential differences by race. PMID- 29188594 TI - Correction to: Community reporting of ambient air polychlorinated biphenyl concentrations near a Superfund site. AB - The original version of this article unfortunately contains a mistake. The correct Author names should be Staci M. Rubin and Keri C. Hornbuckle. PMID- 29188595 TI - Ethanol traces in natural waters checked using a new DMFC enzymatic device. AB - The use of fuels with strong percentage of ethanol that is done in countries such as Brazil and Australia causes a more and more relevant presence of traces of ethanol in natural waters. The ethanol present in these fuels seems to contribute to increase, through various mechanisms, the concentration of hydrocarbons in the same waters and soil. The ethanol content in natural waters must therefore be monitored frequently. It was therefore proposed a very simple innovative method, based on a catalytic fuel cell with the alcohol dehydrogenase enzyme immobilized in the anodic compartment of the device. The analytical performances of this new device were then evaluated by checking traces of alcohol in different types of natural waters (rain, river, and groundwater), with a good degree of precision and with an acceptable level of accuracy. PMID- 29188596 TI - Observed differentials in the levels of selected environmental contaminants among Mexican and other Hispanic American children, adolescents, adults, and senior citizens. AB - Starting with the 2007-2008 cycle, the National Health and Nutrition Examination Survey (NHANES) also oversampled Hispanics other than Mexicans (OHISP) making it possible to treat OHISP as a separate demographic group along with Mexican Americans (MAs), non-Hispanic whites (NHWs), and non-Hispanic blacks (NHBs). Yet, more often than not, OHISP have been merged with MA to form an all-Hispanic demographic group (HISP) thus limiting comparisons between NHW, NHB, and HISP. Consequently, for the first time, this study was undertaken to evaluate differences in the observed levels of selected environmental contaminants between MA and OHISP from five groups of environmental contaminants, namely, polycyclic aromatic hydrocarbons (PAHs), iodine uptake inhibitors (IUIs), environmental phenols (EPHs), priority pesticides (PPs), and perfluoroalkyl acids (PFAAs). Data for 2007-2010 from NHANES were used to conduct this study. OHISP children born in USA had higher levels of selected PAH metabolites than USA-born MA, and Mexican born MA adolescents had higher levels of selected PAH metabolites than USA-born MA adolescents. USA-born adolescent MA had higher levels of selected parabens than USA-born adolescent OHISP, and OHISP adults born in another Spanish-speaking country had higher levels of selected parabens than USA-born OHISP adults. USA born MA adults and seniors had higher levels of selected dichlorophenols than Mexico-born MA adults and seniors, respectively. Females had higher levels of selected PAH metabolites, EPHs, and PPs than males among children, adolescents, adults, and seniors, but the reverse was true for the levels of selected IUIs and PFAAs among adolescents and seniors. Smokers had higher levels of almost all PAH metabolites than non-smokers for adolescents, adults, and seniors. The same was true for urinary thiocynate for adolescents, adults, and seniors. OHISP is a multiracial multiethnic demographic group substantially different from MA with possibly different smoking behavior and with possibly differential levels of exposure to certain environmental contaminants and as such should be treated as a demographic group by itself. PMID- 29188597 TI - Association of urinary concentrations of four chlorophenol pesticides with cardiometabolic risk factors and obesity in children and adolescents. AB - This study was undertaken to determine the association of four chlorophenol pesticides with cardiometabolic risk factors and obesity in children and adolescents. This cross-sectional study was conducted in 2016 on 242 children and adolescents, aged 6 to 18 years. The concentrations of 2,4-dichlorophenol (2,4 DCP), 2,5-dichlorophenol (2,5-DCP), 2,4,5-trichlorophenol (2,4,5-TCP), and 2,4,6 trichlorophenol (2,4,6-TCP) in the urine were examined and their association with indices of obesity and cardiometabolic risk factors was determined. Multivariate linear regression and multinomial logistic regression analyses were applied. Overall, 242 participants with mean (SD) ages of 11.3 (2.5) years completed the survey. After adjustment for confounders, a significant positive association was found between body mass index (BMI) z-score and waist circumference (WC) with 2,5 DCP (0.07 (95% CI 0.04, 0.1)) and 0.79 (95% CI 0.54, 1.03), respectively. A significant association of 2,4,5-TCP was only found with WC (0.23 (95% CI 0.0, 0.46), but the relationship with 2,4-DCP was not significant. 2,5-DCP had a significant relationship only with obesity (1.09 (95% CI 1.1, 1.19)), while 2,4 DCP and 2,4,5-TCP showed no significant correlation with overweight or obesity. 2,4-DCP showed a significant positive relationship with high density lipoprotein cholesterol (HDL-C). Moreover, 2,5-DCP showed a significant negative relationship only with systolic blood pressure and 2,4,5-TCP had a statistically significant inverse association with total cholesterol and HDL-C (-0.71 (95% CI -0.98, 0.45)). This study suggests potential associations of chlorophenol pesticides with overweight, obesity, lipid profile, and blood pressure in children and adolescents. Longitudinal studies are necessary to assess the clinical impact of these findings. PMID- 29188598 TI - Influence of Phoslock(r) on legacy phosphorus, nutrient ratios, and algal assemblage composition in hypereutrophic water resources. AB - Acceleration of eutrophication in freshwater resources can result in prolific growth of nuisance algae, notably cyanobacteria. In this research, we evaluated the ability of an in situ P binding technology (Phoslock(r)) to alter available water column and sediment P, and the subsequent impact on nutrient ratios and algal assemblage composition. Two golf course irrigation ponds with legacy nutrient loads and chronic cyanobacterial blooms were treated with Phoslock and monitored for 2 years post-treatment. Phoslock significantly (P < 0.05) decreased water column total P levels and shifted mobile sediment P fractions (i.e., labile, reductant-soluble, organic) to the residual fraction. Total N/P ratios (by mass) significantly increased and were sustained at over 30:1 in the Hickory Meadows irrigation pond and 100:1 in the Chockyotte irrigation pond throughout the study. Consequent changes in the algal assemblage included decreases in dominance and overall density of cyanobacteria as well as a shift away from scum forming genera (e.g., Microcystis spp. and Anabaena [Dolichospermum] sp.) to planktonic forms (e.g., Pseudanabaena sp. and Planktolyngbya sp.). This research provides information regarding mitigation of in situ water and sediment P toward shifting nutrient ratios and altering algal assemblage composition. PMID- 29188600 TI - Killing two birds with one stone: The multifunctional roles of mesenchymal stem cells in the treatment of neurodegenerative and muscle diseases. AB - Neurodegenerative and muscle diseases bear both complex and multifactorial pathologies. An efficacious and robust therapeutic option to treat these diseases is yet to be elucidated. At such a time, mesenchymal stem cells have drawn significant attention due to their immunomodulatory and regenerative properties. Accumulating evidence has proposed the capability of MSCs to serve multiple roles in a broad spectrum of diseases by secretion of trophic or paracrine factors. In the present review, we will look into the recent literature and discuss the therapeutic functions of MSCs and their potential to treat various neurodegenerative (Alzheimer's, Parkinson's, and Huntington's disease) and muscle (Duchenne muscular dystrophy, myopathy, and multiple sclerosis) diseases. PMID- 29188599 TI - Chemical characterization of PM2.5 collected from a rural coastal island of the Bay of Bengal (Bhola, Bangladesh). AB - This work focuses on the chemical characterization of fine aerosol particles (PM2.5) collected from a rural remote island of the Bay of Bengal (Bhola, Bangladesh) from April to August, 2013. PM2.5 particle-loaded filters were analyzed for organic carbon (OC), elemental carbon (EC), water-soluble ions, and selected saccharides (levoglucosan, mannosan, galactosan, arabitol, and mannitol). The average PM2.5 mass was 15.0 +/- 6.9 MUg m-3. Organic carbon and elemental carbon comprised roughly half of the analyzed components. Organic carbon was the predominant contributor to total carbon (TC) and accounting for about 28% of PM2.5 mass. Secondary organic carbon (SOC) was inferred to be ~ 26% of OC. The sum of ions comprised ~ 27% of PM2.5 mass. The contribution of sea salt aerosol was smaller than expected for a sea-near site (17%), and very high chloride depletion was observed (78%). NssSO42- was a dominant ionic component with an average concentration of 2.0 MUg m-3 followed by Na+, NH4+, and nssCa2+. The average concentration of arabitol and mannitol was 0.11 and 0.14 MUg m-3, respectively, while levoglucosan and its stereoisomers (mannosan and galactosan) were bellow detection limit. NH4+/SO42- equivalent ratio was 0.30 +/- 0.13 indicating that secondary inorganic aerosol is not the main source of SO42-. Enrichment factor (EF) analysis showed that SO42- and NO3- were enriched in atmospheric particles compared to sea aerosol and soil indicating their anthropogenic origin. Higher OC/EC ratio (3.70 +/- 0.88) was a good indicator of the secondary organic compounds formation. Other ratios (OC/EC, K+/EC, nssSO42 /EC) and correlation analysis suggested mixed sources for carbonaceous components. Arabitol and mannitol both showed strong correlation with EC having R 2 value 0.89 and 0.95, respectively. Air mass trajectories analysis showed that concentrations of soil and anthropogenic species were lower for air masses originating from the sea (May-August) and were higher when air came from land (April). PMID- 29188601 TI - [Analysis of SCN1A deletions or duplications in patients with Dravet syndrome]. AB - OBJECTIVE: To determine the type and frequency of SCN1A deletions and duplications among patients with Dravet syndrome (DS). METHODS: For DS patients in which no mutations of the SCN1A gene were detected by PCR-DNA sequencing, SCN1A deletions and duplications were detected by multiplex ligation-dependent probe amplification (MLPA). RESULTS: In 680 DS patients, 489 had SCN1A mutations identified by PCR-DNA sequencing. In 191 patients who were negative for the SCN1A PCR-DNA sequencing, 15 (15/191, 7.9%) were detected with heterozygous SCN1A deletions or duplications, which included 14 (14/15, 93.3%) SCN1A deletions and 1 SCN1A duplication. There were 13 types of mutations, including whole SCN1A deletions in 3 patients, partial SCN1A deletions in 11 patients and partial SCN1A duplications in one patient. By testing the parents, 14 mutations were found to be de novo. For the remaining case, no SCN1A deletion or duplication was found in the mother, while the father was not available. CONCLUSION: Approximately 8% of Chinese patients who were negative for SCN1A mutation by PCR-sequencing have SCN1A deletions or duplications. The MLPA analysis should be considered as an important strategy for such patients. SCN1A deletions are more common than SCN1A duplications among DS patients, and the most common types are whole SCN1A deletions. The majority of SCN1A deletions or duplications are de novo. PMID- 29188602 TI - [Rare thalassemia mutations among southern Chinese population]. AB - OBJECTIVE: To detect rare types of thalassemia mutations among southern Chinese population. METHODS: Peripheral blood samples from 327 patients from various regions of southern China were collected. The patients were suspected as rare type thalassemia for their inconsistency between hematological phenotypes and results of routine mutation screening. The samples were further analyzed with GAP PCR and DNA sequencing. RESULTS: One hundred and eight cases were diagnosed as rare types of thalassemia. Among whom 10 rare alpha-globin gene mutations including --THAI, HKalpha, alphaalphaalphaanti3.7, alphaalphaalphaanti4.2, alpha2.8, -alpha27.6, CD74 GAC>CAC (Hb Q-Thailand), CD30 (-GAG), CD31 AGG>AAG and CD118 (+TCA), and 12 rare beta-globin gene mutations including CD37 TGG>TAG, CD39 CAG>TAG/CD39 CAG>TAG, beta II-2 (-T), -90(C>T), -31(A>C), -88(C>T), CD7(-A), CD138(+T), CD89-93 (--AGTGAGCTGCACTG), CD54-58 (-TATGGGCAACCCT), Chinese G gamma +(A gammadeltabeta)0 and Vietnamese HPFH (HPFH-6) were identified. -88(C>T) (HBB: c.-138C>T) and CD39 CAG>TAG (HBB: c.118C>T) were discovered for the first time in Chinese population. CD7(-A) (HBB: c.23delA) and CD138(+T) (HBB: c.416_417insT) were new types of beta-globin gene mutations. CONCLUSION: The present study have enriched the mutation spectrum of thalassemia in southern China, which has provided necessary information for its diagnosis.

METHODS: Clinical record of five patients (including one familial case) with osteogenesis imperfecta type V were retrospectively analyzed. Peripheral blood samples of the patients, one family member, as well as healthy controls were collected. Mutation of IFITM5 gene was identified by PCR amplification and Sanger sequencing. RESULTS: A heterozygous mutation (c.-14C>T) in the 5-UTR of the IFITM5 gene was identified in all of the patients and one mother. The clinical findings included frequent fractures and spine and/or extremities deformities, absence of dentinogenesis imperfecta, absence of hearing impairment, and blue sclera in 1 case. Radiographic findings revealed calcification of the interosseous membrane between the radius-ulna in all cases. Hyperplastic callus formation was found in 3 cases. Four had radial-head dislocation. CONCLUSION: A single heterozygous mutation c.-14C>T was found in the 5-UTR of the IFITM5 gene in 5 patients with osteogensis imperfecta type V. The patients showed specific radiological features including calcification of interosseous membrane, hyperplastic callus formation, and radial-head dislocation.

No similar mutations were found among the controls. CONCLUSION: Our data has enriched the mutation spectrum of the Dystrophin gene and may provide an important basis for genetic diagnosis. PMID- 29188605 TI - [Analysis of prognosis of acute myeloid leukemia patients based on genetic mutations]. AB - OBJECTIVE: To correlate the clinical features of patients with acute myeloid leukemia (AML) with mutations of FLT3-ITD, NPM1, CEBPA, c-KIT, DNMT3A and ND4 genes as well as chromosomal aberrations. METHODS: Somatic mutations of aforementioned genes in 412 newly diagnosed AML patients were detected with PCR and direct sequencing. All patients were also subjected to R-banding chromosomal analysis. The results were correlated with the clinical features and prognosis of the patients. RESULTS: The mutation rates of FLT3-ITD, NPM1, CEBPA, c-KIT, DNMT3A and ND4 were 9.0% (26/289), 19.1% (50/262), 18.9% (34/180), 3.4% (7/208), 6.6% (9/137) and 6.9% (4/58), respectively. Patients with poor prognosis based on genetic mutations had lower blood platelet count than those with intermediate and good prognosis (P=0.001 and P=0.001, respectively). None of the three groups attained median overall survival (OS) (P> 0.05). The complete remission (CR) was similar among the three groups (P> 0.05). For patients with different prognosis based on cytogenetic findings, white blood cell count in those with intermediate prognosis was higher than those with good and poor prognosis (P< 0.001 and P=0.004, respectively), while the blood platelet count of the intermediate group was higher than that of the group with good prognosis (P=0.018). No significant difference was found among the three groups in terms of hemoglobin level (P> 0.05). The group with poor prognosis has attained shorter OS compared with those with good and intermediate prognosis (P< 0.001 and P=0.003, respectively). However, the CR rate of the group with good prognosis was higher than that of the intermediate group (P=0.001). For the group with intermediate prognosis, presence of genetic mutations did not correlate with the clinic characteristics such as white blood cell count, blood platelet count, hemoglobin level, OS and CR rate (P> 0.05 for all comparisons). CONCLUSION: Genetic mutations combined with cytogenetic analysis can facilitate the prognosis and personalized treatment for patients with AML.

AB - OBJECTIVE: To carry out chromosomal microarray analysis (CMA) on four fetuses with abnormal karyotypes. METHODS: Amniotic fluid samples were obtained and subjected to routine G-banded karyotyping analysis. CMA was applied for cultured amniocytes to determine alterations of gene dosage and chromosomal breakpoints. RESULTS: Abnormal karyotypes were found in the parents of 3 fetuses. Parental karyotypes of the remaining fetus were normal. Imbalance chromosome rearrangements were revealed by CMA in all 4 cases. CONCLUSION: CMA is an effective tool for the evaluation of clinical significance and delineation of the breakpoints involved in complex chromosomal rearrangements. PMID- 29188607 TI - [NOTCH3 gene mutations in two Chinese families featuring cerebral autosomal dominant arteriopathy with subcortical infarct and leucoencephalopathy]. AB - OBJECTIVE: To analyze potential mutations of the NOTCH3 gene in two Chinese families featuring cerebral autosomal dominant arteriopathy with subcortical infarct and leucoencephalopathy (CADASIL). METHODS: The two probands and related family members and 100 healthy controls were recruited. Potential mutations of the NOTCH3 gene were screened by PCR and direct sequencing. PolyPhen-2 and SIFT software were used to predict the protein function. RESULTS: The conditions of both probands were adult-onset, with main clinical features including recurrent transient ischemic attacks and/or strokes, cognitive impairment. MRI findings suggested multiple cerebral infarcts and severe leukoencephalopathy. A heterozygous mutation c.328C>T (p.Arg110Cys), which was located in exon 3 of the NOTCH3 gene and known as a causative mutation, was identified in proband 1. A novel heterozygous mutation c.1013 G>C (p.Cys338Ser) located in exon 6 of the NOTCH3 gene was identified in the proband 2, which was not reported previously. The same mutations were not detected among the 100 unrelated healthy controls. Function analysis suggested that heterozygous mutation c.1013G>C can severely affect the functions of NOTCH3 protein. CONCLUSION: Two heterozygous missense mutations in the NOTCH3 gene have been identified in two families affected with CADASIL. The novel heterozygous Cys338Ser mutation in exon 6 of the NOTCH3 gene probably underlies the CADASIL. PMID- 29188608 TI - [CADASIL with clinical manifestations of baldness, lumbago and Parkinson's symptoms]. AB - OBJECTIVE: To investigate a cerebral autosomal dominant arteriopathy with the subcortical infarcts and leukoencephalopathy (CADASIL) case with clinical manifestations of baldness, lumbago and Parkinson's symptoms. METHODS: Clinical and imaging data of the patient were analyzed. The patient and his family members were also subjected to genetic testing. RESULTS: The symptoms of the patient included recurrent stroke, dementia, and mood disturbance, in addition with lumbago, baldness and Parkinson's symptoms but no migraine. Cranial MRI of the patient showed bilateral symmetric leukoencephalopathy and multiple small subcortical lacunar infarcts. A point mutation in exon 11 of the NOTCH3 gene (R558C) was discovered in the proband and four asymptomatic relatives. CONCLUSION: CADASIL is characterized by recurrent subcortical ischemic stroke, dementia, pseudobulbar palsy, and mood disturbance. Baldness, lumbago and Parkinson's symptoms may also be seen in such patients. PMID- 29188609 TI - [Clinical and genetic analysis of two unrelated patients with Angelman syndrome and novel UBE3A mutations]. AB - OBJECTIVE: To explore the genetic cause for two familial Angelman syndrome cases and correlation between the clinical phenotypes and their genetic basis. METHODS: Karyotyping analysis and microarray assay were carried out to exclude chromosome anomalies and uniparental disomy. The UBE3A gene was analyzed for potential point mutations, deletions, insertions and splice site mutations. Reverse transcription PCR was used to evaluate splicing mutation of the RNA transcripts. RESULTS: DNA sequencing showed the proband of family 1 has carried a novel maternal UBE3A splice acceptor site mutation, resulting in a guanine-to-cytosine transversion (IVS15-1G>C). Reverse transcription PCR revealed the proband and his mother both carried heterozygous mutant transcripts with loss of 54 and 59 nucleotides in exon 16, respectively. The proband displayed severe mental retardation, ataxia, seizures and inappropriate laughter. The siblings of family 2 has carried a novel maternal missense mutation in exon 16 of the UBE3A gene (c.2540C>T). She also presented with mental retardation, absent speech, mild ataxia and inappropriate laughter. CONCLUSION: The novel IVS15-1G>C and c.2540 C>T mutations of the UBE3A gene probably underlie the AS in the two families. Compared with small-scale mutations, larger fragments mutations can produce more severe phenotypes. PMID- 29188610 TI - [Genetic analysis of two pediatric patients with Beckwith-Wiedemann syndrome]. AB - OBJECTIVE: To explore the genetic cause for two children with omphalocele. METHODS: The patients were examined, and the medical history of their families was collected. Methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) was performed to detect potential mutation in the patients. RESULTS: Loss of methylation of imprinting center 2 (IC2) at the 11p15.5 region of the maternal chromosome was detected in both children. CONCLUSION: The two patients were diagnosed with Beckwith-Wiedemann syndrome by MS-MLPA. The loss of methylation of IC2 probably underlies the disease in both patients. PMID- 29188611 TI - [Application of next generation sequencing for the analysis of patients with spontaneous abortion]. AB - OBJECTIVE: To assess the value of next generation sequencing (NGS) for the analysis of spontaneous abortion samples. METHODS: The NGS analysis was carried out on 85 chorionic villi samples (taken between 42 days to 12 weeks of gestation) for which conventional cell culture has failed or chromosomal karyotyping has yielded normal or uncertain result. RESULTS: Among 68 samples with a normal karyotype, the NGS analysis has identified 2 copy number variations (CNVs) and 2 chimeras. For 16 cases with failed cell culture, the NGS has identified 4 chromosomal abnormalities including 1 copy number variation and 3 numerical chromosomal aberrations. For 1 remaining case with uncertain karyotyping result, the NGS analysis has verified it as 46,XX,del(4) (p15.1p16.3).seq[GRCh37/hg19] (57 549 - 32 371 364)*1. CONCLUSION: The NGS analysis is capable of identifying novel CNVs in samples for which conventional cell culture may fail or karyotyping analysis may yield a normal result. PMID- 29188612 TI - [Influence of CYP2C19 gene polymorphisms on the efficacy of clopidogrel treatment for the prevention of ischemic stroke following coronary stent implantation]. AB - OBJECTIVE: To assess the association of CYP2C19 gene polymorphisms with the incidence of ischemic stroke among patients receiving clopidogrel therapy following coronary stenting for coronary artery disease. METHODS: Clinical data of patients receiving clopidogrel therapy after coronary stenting were retrospectively studied. For a case-control study, 137 patients with acute cerebral infarction and 122 non-stroke patients were selected. Based on the variants of the CYP2C19 gene detected by a DNA microarray assay, the patients were further divided into the wild-type group(CYP2C19*1/*1) and mutant group(defined by the presence of at least one loss-of-function allele, including CYP2C19*1/*2, CYP2C19*1/*3, CYP2C19*2/*2, CYP2C19*2/*3 and CYP2C19*3/*3). The incidences of ischemic stroke in the two groups were compared through a chi square analysis. The influence of CYP2C19 gene polymorphisms and clopidogrel therapy on the incidence of ischemic stroke was analyzed through multivariable logistic regression. RESULTS: A total of 259 patients were enrolled. The case and control groups showed no difference in terms of gender and age. There were 123 cases (47.5%) in the CYP2C19 wild-type group and 136 cases (52.5%) in the mutant group. The incidence of ischemic stroke of mutant group was significantly higher than that of wild-type group (59.9% vs. 44.3%, X2=6.398, P=0.042). Multivariate analysis revealed that loss-of-function polymorphisms of the CYP2C19 gene carried a 1.13 times greater risk for ischemic stroke compared to wild-type genotype (OR=2.13, 95%CI: 1.23-3.71). CONCLUSION: The efficacy of clopidogrel for the prevention of ischemic stroke in post-coronary stent patients may be reduced by the insufficiency of the CYP2C19 gene. The dosage of clopidogrel therapy should be adjusted based on its polymorphisms. PMID- 29188613 TI - [Exploration of common biological pathways for attention deficit hyperactivity disorder and low birth weight]. AB - OBJECTIVE: To explore common biological pathways for attention deficit hyperactivity disorder (ADHD) and low birth weight (LBW). METHODS: Thei Gsea4GwasV2 software was used to analyze the result of genome-wide association analysis (GWAS) for LBW (pathways were derived from Reactome), and nominally significant (P< 0.05, FDR< 0.25) pathways were tested for replication in ADHD.Significant pathways were analyzed with DAPPLE and Reatome FI software to identify genes involved in such pathways, with each cluster enriched with the gene ontology (GO). The Centiscape2.0 software was used to calculate the degree of genetic networks and the betweenness value to explore the core node (gene). Weighed gene co-expression network analysis (WGCNA) was then used to explore the co-expression of genes in these pathways.With gene expression data derived from BrainSpan, GO enrichment was carried out for each gene module. RESULTS: Eleven significant biological pathways was identified in association with LBW, among which two (Selenoamino acid metabolism and Diseases associated with glycosaminoglycan metabolism) were replicated during subsequent ADHD analysis. Network analysis of 130 genes in these pathways revealed that some of the sub networksare related with morphology of cerebellum, development of hippocampus, and plasticity of synaptic structure. Upon co-expression network analysis, 120 genes passed the quality control and were found to express in 3 gene modules. These modules are mainly related to the regulation of synaptic structure and activity regulation. CONCLUSION: ADHD and LBW share some biological regulation processes. Anomalies of such proces sesmay predispose to ADHD. PMID- 29188614 TI - [Clinical and genetic analysis of a boy with 9q34.3 microdeletion syndrome]. AB - OBJECTIVE: To determine the origin of chromosomal aberration in a boy with mental retardation and multiple congenital malformations. METHODS: The karotypes of the proband and his parents were analyzed with conventional G-banding. Their genomic DNA was analyzed with array comparative genomic hybridization (aCGH). RESULTS: No karyotypic abnormality was detected in the proband and his parents. aCGH has identified a de novo 405 kb deletion at 9q34.3 in the proband, which encompassed the EHMT1 gene and part of CACNA1B gene. CONCLUSION: The de novo 9q34.3 deletion probably underlies the mental retardation and development delay in the boy. EHMT1 may be one of the key genes responsible for 9q34.3 microdeletion syndrome. PMID- 29188616 TI - [Prenatal diagnosis of a tetrasomy 18p case using BACs-on-Beads technology and single nucleotide polymorphism array]. AB - OBJECTIVE: To determine the origin of a supernumerary small marker chromosome found in a fetus using prenatal BACs-on-Beads (BoBs) and single nucleotide polymorphism array (SNP-array) assays. METHODS: The fetal sample was subjected to chromosomal karyotyping and BoBs analysis, and the results were validated with genome-wide scanning using a SNP microarray. RESULTS: The fetus was found to have a 47,XX,+mar karyotype. BoBs analysis indicated that there was an amplification between 18p11.32 and 18p11.21, which was verified by the SNP-array assay as a 18.3 Mb duplication occurring at 18p11.32q11.1. CONCLUSION: The karyotype of the fetus was determined as 47,XX,+der18(18p11.32?18q11.1::18q11.1?18p11.32). The duplication has involved important genes including SMCHD1, LPIN2 and TGIF1, which may result in severe malformations in the fetus. PMID- 29188615 TI - [Prenatal diagnosis of two fetuses with chromosome 1p36 deletion syndrome]. AB - OBJECTIVE: To analyze two fetuses with multiple malformations revealed by ultrasonography using single nucleotide polymorphism array (SNP array), and to explore the strategy for the prenatal diagnosis of 1p36 deletion syndrome. METHODS: Amniocentesis was performed on the two pregnant women. Amnion fluid cells were cultured, and karyotypes of the fetuses were determined through G banding analysis. Whole genome SNP array was used to detect genomic anomalies of the two fetuses. The karyotypes of their parents were determined through G banding analysis of peripheral venous blood samples. RESULTS: G-banding analysis showed a 46,XY,add(1p36)? and a 46,XX,add(1p36)? karyotype for fetuses 1 and 2, respectively. SNP array analysis showed that the fetus 1 had arr[19]1p36.33p36.32 (752 566 - 3 393 462)*1 and 7q35q36.3 (144 480 549 - 159 119 486)*3, and fetus 2 had arr[19]1p36.33p36.23 (752 566 - 8 362 754)*1, 6p25.3p22.3 (204 909 - 20 182 185)*3. The mother of fetus 1 had a 46,XX,t(1;7)(p36;q35) karyotype, and the mother of fetus 2 had a 46,XX,t(1;6)(p36;p22) karyotype. The karyotypes of both fathers appeared to be normal. CONCLUSION: SNP array has the advantages such as high sensitivity and high accuracy for prenatal diagnosis, and can provide more detailed information for genetic counseling of 1p36 deletion syndrome. PMID- 29188617 TI - [SNP array analysis of three cases with partial 21q trisomy]. AB - OBJECTIVE: To analyze three cases with partial 21q trisomy, and correlate their genotypes with phenotypes. METHODS: G-banding chromosomal analysis and single nucleotide polymorphism (SNP array) were performed for the three cases and their parents. RESULTS: SNP array has detected partial 21q trisomy in three cases and one mother, with variable size and location of the duplications. Case 1 harbored a 12.35 Mb duplication at 21q22.11q22.3, which spanned the Down syndrome critical region. Case 2 harbored a 35.32 Mb duplication at 9p24.3p13.3 and a 14.42 Mb duplication at 21q11.2q21.3, with the former spanning the partial 9p trisomy syndrome critical region excluding the Down syndrome critical region, and was inherited from his mother. Case 3 harbored a 4.17 Mb tetraploidy at 21q11.2q21.1 in the form of mosaicism, which spared the Down syndrome critical region. His mother carried a 4.17 Mb triploidy at 21q11.2q21.1, which was also a mosaicism. CONCLUSION: Partial 21q trisomy may occur in various forms and its clinical phenotypes are heterogeneous. Combined use of genetic techniques, particularly SNP array, is crucial for diagnosing partial 21q trisomy and delineating its genotype-phenotype correlation. PMID- 29188618 TI - [Identification of novel compound heterozygous mutations in the ANTXR2 gene in a Chinese patient with juvenile hyaline fibromatosis]. AB - OBJECTIVE: To identify pathogenic mutations of ANTXR2 gene in a patient with juvenile hyaline fibromatosis. METHODS: Genomic DNA was extracted from peripheral venous blood sample from the patient. All coding exons (exons 1-17) and splicing sites of the ANTXR2 gene were amplified with PCR. Potential mutations were detected with direct sequencing of the PCR products. 100 unrelated healthy subjects were used as the controls. CLUSTALX (1.81) was employed to analyze cross species conservation of the mutant amino acid. Impact of the mutations was analyzed with software including SIFT, PolyPhen-2 and MutationTaster. RESULTS: A compound heterozygous mutation c.1074delT/c.1153G>C, was identified, among which c.1153G>C has not been reported previously and was predicted to be probably damaging. Both mutations were not found among the 100 healthy controls. CONCLUSION: The patient's condition may be attributed to the compound heterozygous mutations of c.1074delT and c.1153G>C of the ANTXR2 gene. Above results has facilitated molecular diagnosis for this patient. PMID- 29188619 TI - [Detection and prenatal diagnosis of TOR1A gene mutation in a Chinese family affected with dystonia]. AB - OBJECTIVE: To explore the feasibility of using PCR-based capillary electrophoresis method to analysis mutation of the TOR1A gene in a family affected with primary torsion dystonia (PTD). METHODS: Peripheral blood sample was collected from proband and amnionic fluid from her fetus for the extraction of DNA. The 5th exon of the TOR1A gene and its flanking sequences were amplified with PCR and analyzed with agarose electrophoresis, fluorescence labeled fragment analysis and Sanger sequencing. RESULTS: Fluorescence labeled fragment analysis was performed through capillary electrophoresis, which showed that the proband carried a c.907_909delGAG (p.Glu303del) deletional mutation of the TOR1A gene. The result was verified by Sanger sequencing. The fetus DNA was also found with the same mutation by capillary electrophoresis, inferring that the fetus was probably affected with the disease. CONCLUSION: The mutation of c.907_909delGAG of the TOR1A gene was speculated as pathologic cause of proband in this family. Fragment analysis by capillary electrophoresis combined with DNA sequencing is an efficient test for small deletional mutations and feasible for its prenatal diagnosis. PMID- 29188620 TI - [Analysis of genotype and phenotype of SEC23B gene in a family affected with congenital dyserythropoietic anemia type II]. AB - OBJECTIVE: To detect potential mutation in a family affected with congenital dyserythropoietic anemia type II (CDA II). METHODS: Targeted sequence capture and next-generation sequencing (NGS) were used to analyze the exons and exon-intron boundaries of the SEC23B gene in a clinically suspected CDA II patient. Genotypes of the relatives were validated by Sanger sequencing. Potential impact of amino acid substitution on the structure and function of SEC23B protein was predicted with MutationTaster and PolyPhen-2. The protein structure was predicted with SWISS-MODEL software. RESULTS: The proband was found to harbor double heterozygous mutations of the SEC23B gene, c.1727T>C (p.F576S) and c.1831C>T (p.R611W), which resulted in amino acid substitutions p.F576S and p.R611W. Both mutations were confirmed by Sanger sequencing. The sister of the proband was found to have carried c.1727T>C (p.F576S), while her father and son have carried c.1831C>T (p.R611W) mutation. In addition, the proband was detected to have carried c.211C>T (p.R71X) of the HFE gene, which resulted in substitution of arginine by a stop codon. The impact of above mutations on the structure or function of protein was predicted to be harmful. Splenectomy and iron chelation therapy have achieved effective improvement of anemia and iron overload. Computer simulation suggested that the mutations have altered the 3D structure of the SEC23B protein. CONCLUSION: The novel compound mutations of c.1727T>C and c.1831C>T of the SEC23B gene probably underlie the CDA II in the family, and there is a strong correlation between the genotype and phenotype. PMID- 29188621 TI - [Prenatal diagnosis of a fetus with Miller-Dieker syndrome]. AB - OBJECTIVE: To report on prenatal diagnosis of a fetus with Miller-Dieker syndrome (MDS) and explore its genotype - phenotype correlation. METHODS: Chromosome karyotyping, bacterial artificial chromosome on beads (BACs-on-Beads, BoBs), fluorescence in situ hybridization (FISH), and single nucleotide polymorphism microarray (SNP array) were applied in conjunction for the prenatal diagnosis of a fetus with abnormal ultrasound findings. RESULTS: A 17p13.3 microdeletion was detected with the BoBs assay, and the result was confirmed by FISH. With the SNP array, the deletion was mapped to chromosome 17, with its range determined to be 5.2 Mb. On high-resolution banding analysis and BoB assay, the deletion was not found in either parent. CONCLUSION: The combined use of BoBs, FISH and SNP array has enabled prenatal diagnosis of a fetus with MDS. Attention should be paid to microdeletions and microduplications which can be missed by conventional chromosomal karyotyping analysis. PMID- 29188622 TI - [Two false negative cases in noninvasive prenatal testing for fetal chromosomal aneuploidies]. AB - OBJECTIVE: To explore the limitation of non-invasive prenatal testing (NIPT) technique through analyzing two false negative cases. METHODS: Chromosomal karyotyping analysis was performed on umbilical cord blood sample derived from case 1 at 24 weeks' gestation and peripheral blood sample derived from the neonate of case 2. Placental tissues of case 1 and peripheral blood sample of case 2 were also analyzed by high-throughput sequencing for copy number variations (CNVs). RESULTS: For case 1, analysis of fetal umbilical cord blood sample showed a translocation type of trisomy 21, i.e., 46,XY,der(21;21)(q10;q10),+21. There were no obvious abnormalities detected at or near the center of the fetal surface and matrix surface of the placenta. High thoroughput sequencing showed Chr13:(33 840 001 - 115 100 000)*3[60%]/46,XY[40%] at the edge of the placenta, Chr13:(34 080 001-115100000)*3[54%]/46,XY[46%] at the edge of placenta matrix surface, and trisomy 21 in the umbilical cord tissue. For case 2, analysis of the neonatal peripheral blood sample showed a karyotype of 46,XY,del(18)(q22), which revealed a microdeletion in chromosome 18. High throughput sequencing of the maternal peripheral blood sample stored during pregnancy confirmed it to be chr18: (62 910 000 - 78 020 000)*1 with 15.1 Mb deletion in the fetus. The neonate was therefore diagnosed with partial monosomy of chromosome 18. CONCLUSION: False negative results of NIPT are related with the fraction of circulating cell-free fetal DNA in the maternal serum. NIPT has limitations in detecting fetal chromosomal microdeletion and confined placenta mosaicisms. Routine ultrasound scan is necessary for pregnant women with low-risk indicated by NIPT. PMID- 29188623 TI - [Pedigree investigation and genetic analysis of a case with Vel heterozygous deletion mutation]. AB - OBJECTIVE: To analyze an individual with SMIM1 c.64_80 heterozygous deletional mutation and his family members. METHODS: Based on the molecular basis of Vel negative blood type, PCR primers specific for SMIM1 wild-type allele and c.64_80del allele were designed. PCR-sequence specific primer (PCR-SSP) and Sanger sequencing were employed to determine the genotype of all subjects. Inheritance of the Vel blood group system was investigated by pedigree analysis. RESULTS: PCR-SSP and DNA sequencing demonstrated that the proband was heterozygous for the SMIM1 c.64_80del allele. Pedigree investigation showed that his father had the same mutation, while his mother and elder sister were of wide type. No individual with homozygous c.64_80del allele was found. CONCLUSION: PCR SSP and DNA sequencing confirmed that the proband was heterozygous for the c.64_80del mutation. The mutation inherits form his father. PMID- 29188624 TI - [Identification of a novel Bx allele of the ABO blood group]. AB - OBJECTIVE: To identify a novel Bx13 allele. METHODS: Serological characteristics was determined with standard serological methods. All of the seven exons and flanking regions of the ABO gene were analyzed with PCR and direct sequencing. The amplicon of exon 7 was also cloned and sequenced. RESULTS: The individual was determined as with a rare Bx phenotype by serological tests. Direct DNA sequencing showed that the individual was heterozygous for the B/O01 allele, while there was a novel 893C>T mutation in the B101 allele, which has led to an amino acid substitution Ala298Val in the alpha,3-D-galactosyl-transferase. The mutation was not found among 100 randomly selected blood donors. CONCLUSION: A novel Bx13 allele has been identified. Substitution of amino acid in the conserved region of the enzyme may reduce the activity of alpha,3-D-galactosyl transferase. PMID- 29188625 TI - [Identification of a novel ABO B(A)07 allele]. AB - OBJECTIVE: To explore the molecular basis for a novel B(A) phenotype. METHODS: Genomic DNA was abstracted from peripheral blood sample from the proband. ABO genotyping were carried out with sequence specific primer PCR (PCR-SSP). Exons 6 and 7 of the ABO gene were amplified with PCR and sequenced. RESULTS: Anti-A serum could not be adsorbed or eluted by the donor's red blood cells, and no irregular antibodies were found in the plasma. PCR-SSP showed that the ABO genotype of the donor was ABO *B/O.

AB - OBJECTIVE: To study the molecular mechanism and polymorphism of D gene of RhD negative and D variants among voluntary blood donors from Qingdao region. METHODS: For 220 D-negative phenotype cases and 5 D variant cases confirmed by serological test, exons 1 to 10 of the RHD gene were detected by a PCR-SSP method. The samples which contain all or part of the exons were sequenced. RESULTS: Among the 220 cases, 166 (75.45%) had complete absence of the RHD gene, while 54 (24.55%) had retained some or all of the 10 exons. Eight genotypes were identified, which included RHD 1227G>A in 28 cases (12.73%), RHD-CE- (2-9) -D in 19 cases (8.64%), RHD-CE- (3-7)-D in 1 case (0.45%), RHD 3G>A in 1 case (0.45%), RHD 711delC in 2 cases (0.91%), RHD 845G>A in 1 case (0.45%), RHD 1013T>C in 1 case (0.45%), and RHD 1227A/G in 1 case (0.45%). No mutation was found in all of the 10 exons. Two alleles were identified in the 5 cases of D variants, which included RHD 845G>A (4 cases) and RHD 697G>A (1 case). CONCLUSION: Absence of the whole RHD gene is common among RhD negative blood donors from Qingdao region, and there are rich genetic polymorphisms for this locus.

AB - OBJECTIVE: To assess the association of short tandem repeats (STRs) loci with aggressive behaviors of schizophrenia. METHODS: Blood samples from 123 schizophrenic patients with aggressive behaviors and 489 schizophrenic patients without aggressive behaviors were collected. DNA from all samples was amplified with a PowerPlex 21 system and separated by electrophoresis to determine the genotypes and allelic frequencies of 20 STR loci including D3S1368, D1S1656, D6S1043, D13S317, Penta E, D16S639, D18S51, D2S1338, CSF1PO, Penta D, TH01, vWA, D21S11, D7S820, D5S818, TPOX, D8S1179, D12S391, D19S433, and FGA. RESULTS: All of the 20 STR loci have reached Hardy-Weinberg equilibrium in both groups. A significant difference was found in allelic and genotypic frequencies of loci Penta D between the two groups (alleles: P=0.042; genotypes: P=0.014) but not for the remaining 19 loci (P> 0.05). Univariate analysis also showed a significant difference for allele 10 and genotypes 10-12 of Penta D between the two groups (P=0.0027, P=0.0001), with the OR being 1.81 (95%CI: 1.22-2.67) and 4.33 (95%CI: 1.95-9.59), respectively. CONCLUSION: Penta D may be associated with aggressive behaviors of schizophrenia. Allele 10 and genotypes 10-12 of Penta D may confer a risk for the disease. PMID- 29188628 TI - [Effect of MTHFR gene on the schizophrenia and its cognitive function]. AB - OBJECTIVE: To investigate the effect of MTHFR gene on schizophrenia and its cognitive function. METHODS: We recruited 254 schizophrenia patients with stable condition, 339 healthy controls for genetic analysis and 72 healthy controls for cognitive evaluation. The repeatable battery for the assessment of neuropsychological status (RBANS) was used for cognitive measurement. PCR-RFLP technique was carried out to genotype 677C/T polymorphism. RESULTS: There were no significant differences in genotypic or allelic frequencies of the 677C/T polymorphism between the case and control groups (P> 0.05). In the RBANS, patients had higher scores of immediate memory, visuospatial skill, language, attention, delayed memory and total scores than healthy controls (P< 0.01); Patients with different genotypes of 677C/T polymorphism had significant differences in the scores of immediate memory, attention and total scores (P< 0.05). CONCLUSION: Our results did not provide evidence for MTHFR gene conferring susceptibility to schizophrenia. However, there was a significant association between the MTHFR gene and cognitive impairment in patients with schizophrenia, especially in immediate memory and attention.

PMID- 29188638 TI - [Preparation processes of 3% yttria-stabilized tetragonal zirconia polycrystalline ceramic composite powders coated with nano-sized Al2O3-boron nitride]. AB - OBJECTIVE: In this work, we aim to determine the optimum pH value for the preparation of 3% yttria-stabilized tetragonal zirconia polycrystalline (3Y TZP)/3%Al2O3 and optimum calcination temperature of Al2O3 precursor and amorphous boron nitride (BN) for Al2O3-BN coating 3Y-TZP powders. METHODS: The 3Y TZP/3%Al2O3 composite powders were prepared through the heterogeneous precipitation method under different pH values (6.5, 7.5, 8.5, and 9.5) and analyzed through transmission electron microscopy (TEM) to determine the optimum coating morphology. Al2O3 precursor, which was prepared under the optimum pH value, was calcined at different temperatures (800, 1 000, 1 200, and 1 400 C). The amorphous BN coating 3Y-TZP/3%Al2O3 powder was prepared via in situ reaction with boric acid and urea (calcined with N2 at 850 C for 5 and 3 h and 800 C for 5 and 3 h). TEM, energy dispersive spectrometry (EDS), and X-ray diffraction (XRD) were performed to characterize the results. RESULTS: The optimum coating morphology was obtained at 8.5 pH. When the Al2O3 precursor was calcined at 1 200 C and coated with BN (calcined with N2 at 800 C for 5 h), the Al-B-O compound was less, and t-ZrO2 was more represented. CONCLUSIONS: The optimum pH value for 3Y TZP/3%Al2O3 composite preparation is 8.5. For the preparation of Al2O3-BN coating 3Y-TZP powders, the optimum calcination temperature of the Al2O3 precursor and amorphous BN are 1 200 and 800 C, respectively. PMID- 29188639 TI - [Construction of a eukaryotic expression vector of fibroblast activation protein and establishment of its stable over-expression in the oral squamous cell carcinoma]. AB - OBJECTIVE: This study aimed at constructing fibroblast activation protein (FAP) over-expression lentivinus vectors to investigate transfection in SCC9 cell lines and establish a stable FAP over-expression oral squamous cell line. METHODS: The cDNA of FAP gene from an oral squamous cell carcinoma (OSCC) tissue was amplified by polymerase chain reaction (PCR) and subcloned into eukaryotic expression vector pCDH-CMV-MCS-EF1-copGFP. The recombinant plasmid was sequenced and then transfected into an SCC9 cell line. Subsequently, the SCC9 cell line that over expressed FAP stably was established by fluorescence activated cell sorting (FACS). The expression of green fluorescent protein (GFP) was detected with fluorescence microscopy, and the over-expression of FAP was identified by real time PCR and Western blot. RESULTS: The FAP gene was amplified by PCR and then cloned into the vector, whose sequence was identical to that in the GenBank. GFP was expressed in the transfected cells. Furthermore, FAP over-expression in the transfected cells was detected by real-time PCR and Western blot. CONCLUSIONS: The recombinant eukaryotic expression vector pCDH-FAP was constructed successfully. This result provides a foundation for further studies on the function of FAP in vitro. PMID- 29188640 TI - [Role of adenosine triphosphate-sensitive potassium channel in hydrogen sulfide induced inhibition of high glucoseinduced osteoblast damage]. AB - OBJECTIVE: The aim of this study is to identify the role of adenosine triphosphate-sensitive potassium channel (KATP) in hydrogen sulfide (H2S)-induced inhibition of high glucose (HG)-induced osteoblast damage. METHODS: Osteoblasts from rat mandible were cultured and identified. The osteoblasts were then treated with HG, H2S, KATP channel opener pinacidil (Pia), and KATP channel blocker glibenclamide (Gli). Western blot method was performed to detect the expression of KATP channel protein. CCK8, reverse transcriptase polymerase chain reaction (RT-PCR) , and image analysis were used to determine the effects of H2S-KATP on the proliferation, differentiation, and mineralization of osteoblasts. RESULTS: The expression of KATP channel protein in osteoblasts was significantly decreased under the influence of HG. H2S pretreatment significantly inhibited HG on KATP channel protein down-regulation. Moreover, H2S pretreatment significantly inhibited the effect of HG on the proliferation of osteoblasts, thereby preventing HG-induced inhibition of osteoblasts differentiation and mineralization. Meanwhile, the KATP channel blocker effectively blocked the H2S on osteoblasts and had a protective effect. CONCLUSIONS: Through the KATP channel, H2S inhibited osteoblasts damage induced by HG.

AB - OBJECTIVE: This study aimed the role of the CCL5/CCR5 axis in the perineural invasion of salivary adenoid cystic carcinoma (SACC) cells. METHODS: Immunohistochemical analysis and flow cytometric analysis were conducted to detect the expression of the chemokine receptor CCR5 in SACC cells. Enzyme linked immunosorbent assay (ELISA) was performed to determine the expression of CCL5 in the supernate of human nerve cells. The flow cytometric analysis was applied to observe the changes in F-actin in SACC-LM cells, which were pretreated with CCL5. To assess the effects of the CCL5/CCR5 axis on the migration and invasion of SACC LM cells, we performed a scratch test and invasion assay under CCL5 stimulation. RESULTS: CCR5 was highly expressed in SACC cells. The concentration of CCL5 in the supernatant of human nerve cells was (359.2+/-15.8), (696.4+/-22.6) pg.mL-1. The CCL5/CCR5 axis promoted the migration and invasion of SACC-LM cells. CONCLUSIONS: The CCL5/CCR5 axis may be involved in the perineural invasion of SACC cells.

AB - OBJECTIVE: To evaluate vertical stability after various orthognathic surgical treatment plans for skeletal class III malocclusion with anterior openbite. METHODS: A retrospective multicenter cohort study was conducted to investigate vertical stability after various orthognathic surgical treatment plans for skeletal class III malocclusion with anterior openbite. From 2010-2016, 122 patients from two domestic stomatological hospitals were included in our study. Patients were divided into four groups according to their treatment plans, namely, bilateral sagittal split ramus osteotomy (BSSRO), intraoral vertical ramus osteotomy (IVRO), BSSRO+Le Fort I, and IVRO+Le Fort I. All patients followed a standardized examination procedure at 6 and 24 months post-treatment. The observation indexes include overbite, mandibular plane angle, and intermaxillary angle. RESULTS: 1) The significantly reduced ratio of the overbite in the BSSRO+Le Fort I and IVRO+Le Fort I groups were less than the BSSRO and IVRO groups at 6 and 24 months post-treatment. 2) The significantly increased ratio of the mandibular plane in BSSRO+Le Fort I and IVRO+Le Fort I groups were less than BSSRO and IVRO groups at 6 and 24 months post-treatment. 3) The significantly increased ratio of the intermaxillary angles in BSSRO+Le Fort I and IVRO+Le Fort I groups were less than the BSSRO and IVRO groups at 6 months post treatment, while there was no statistical difference at 24 months post-treatment. CONCLUSIONS: Bimaxillary surgery (BSSRO+Le Fort I and IVRO+Le Fort I) is more effective than mandibular surgery to control vertical relapse.

AB - OBJECTIVE: This study was designed to probe the psychological factors adolescent orthodontic patients, the role of body image and self-esteem in the whole process of orthodontic treatment and the impact on the efficacy and satisfaction of orthodontic. METHODS: Five hundred and twenty-eight patients were selected in this study. The Aesthetic Component of the Index of Orthodontic Treatment Need (IOTN-AC) , Rosenberg Self-Esteem Scale (SES), Negative Physical Self-General (NPS-G) and other body analysis scale study after orthodontic lasted 18-24 months were used to investigate the role of body image in adolescent orthodontic treatment. RESULTS: Esthetic evaluation of patients teeth after correction had been significantly improved, patient self-evaluation difference IOTN-AC doctor evaluation, Psychosocial Impact of Dental Aesthetics Questionnaire-tooth confidence, aesthetic concerns, psychological impact and social function were significantly improved. The improvement of the dental aesthetics component (T2 when doctors evaluate IOTN-AC) was positively correlated with the evaluation of the efficacy, and was significantly negatively correlated with the negative emotions of patients at baseline. CONCLUSIONS: Negative body image-dental dissatisfied-cognitive component and the affective component, the overall negative body image and negative emotions can predict patient satisfaction with treatment efficacy. Orthodontic treatment not only improves the self-aesthetic evaluation of adolescent patients, but also has a positive effect on the mental health of adolescent patients. PMID- 29188644 TI - [Study on using laser Doppler flowmetry to determine the pulpal blood flow of immature maxillary incisors]. AB - OBJECTIVE: This study aimed to evaluate the influence of age on the pulpal blood flow (PBF) of immature maxillary incisors of maxillary incisors, which was detected by laser Doppler flowmetry (LDF). METHODS: LDF was used to detect the PBF value of maxillary central and lateral incisors of a child group (aged 7-13 years old) and a positive control group (aged 18-25 years old), as well as the central incisor of a negative control group (the central incisor had undergone endodontic treatment). We then compared the features of PBF in all groups with the influence of gender and position on PBF. The relation of maxillary central incisor and lateral incisor, age, and maxillary incisor were analyzed. RESULTS: The PBF value of the negative control group was (2.08+/-0.73) PU. The PBF values in the positive control group in central and lateral incisors were (8.49+/-1.88) and (7.52+/-1.82) PU. In the child group, PBF values in central incisors and lateral incisors were (11.31+/-2.21) and (12.18+/-2.65) PU. A significant difference was observed between different groups and between central and lateral incisors (P<0.01). Meanwhile, no significant difference was found in the PBF values between the right and the left parts in both males and females (P>0.05). Age had a linearity negative correlation with the PBF value of incisors in the child group. A linear negative correlation existed between the age and PBF of central and lateral incisors (r=-0.310 and r=-0.510, respectively) (P0.05). The efficacy of the treatment group was significantly better than that of the control group at 4 and 8 weeks (P<0.05). The implants placed in the mandible were significantly better than those placed in the maxilla (P<0.05). CONCLUSIONS: Early intake of Shenggu pills could accelerate the implant bone union, improve the implants' ISQ, and ensure the success rate of the operation. PMID- 29188646 TI - [Application of temporomandibular joint dics reduction in the operation of condylar sagittal fracture]. AB - OBJECTIVE: To explore the selection of temporomandibular joint (TMJ) disc reduction and fixation methods in condylar sagittal fracture surgery. METHODS: A total of 36 patients with condylar fractures were chosen. The follow-up period was more 6 months. All 36 cases of condylar sagittal fracture were fixed with long screw. In the operation, the displaced joint disc was repositioned and fixed. The fixed method included direct suture (22 cases) and anchorage (14 cases). Clinical followups were performed before surgery and 1 month, 3 months, 6 months and 1 year after surgery. Clinicians recorded data related to the Fricton craniomandibular index (CMI) and evaluated the postoperative joint function during followup before surgery and 6 months after surgery. RESULTS: In both groups, function of TMJ significantly improved after surgery. The CMI decreased from 0.213+/-0.162 and 0.273+/-0.154 to 0.059+/-0.072 and 0.064+/-0.068 (P<0.05), respectively. No statistical difference was observed between the two groups in palpation index (PI), dysfunction index (DI) and CMI (P>0.05) before or after surgery. CONCLUSIONS: Both methods could effectively improve the dysfunction of the TMJ caused by trauma. The selection of joint disc reduction and fixation methods is based on the displacement and damage degree of the joint disc.

AB - OBJECTIVE: To explore the role and mechanism of drug delivery systems using growth factor combined with gelatin sponge on accelerating the healing of jaw fracture and to seek better treatment of accelerating the maxillofacial fracture. METHODS: About 100 MUg recombinant human bone morphogenetic protein (BMP)-2 was completely dissolved in 1 mL recombinant bovine basic fibroblast growth factor (bFGF), and the solution (40 MUL) was dropped in gelatin sponge (0.5 cm*0.5 cm*1.0 cm). Then, it was freeze dried and prepared into bFGF/BMP/gelatin sponge delivery systems. The mandibular fracture model on two sides were prepared in 12 New Zealand rabbits and randomly divided into two groups. The left side was the control group, which was only fixed with titanium plates. The right side was the experimental group, in which bFGF/BMP/gelatin sponge delivery systems were put under the titanium plates. General observation, X-ray, and histological examination were taken at 2, 4, and 12 weeks after surgery. RESULTS: After 2 weeks, more fibrous tissues were seen between the fracture ends in the experimental group than in the control group. After 4 weeks, fibrous fracture callus were seen in the fracture gap in the experimental group. The ingrowths of fibrous tissue and blood vessels were seen in the control group. The fracture healing of the experimental group was significantly faster than the control group at 2 and 4 weeks. After 12 weeks, the experimental and control groups all healed completely. CONCLUSIONS: bFGF/BMP/gelatin sponge can accelerate and improve fracture healing; thus, it has better clinical application prospect.

AB - OBJECTIVE: This study aims to investigate the association between interleukin (IL)-10-597 (C/A) single-nucleotide polymorphisms and chronic periodontitis of Moyu Uygur population in Xinjiang Uygur Autonomous Region of China. METHODS: In accordance with the inclusion and exclusion criteria, the buccal swabs of 300 subjects were randomly selected from the epidemiological investigation of Uygur adults in Moyu county on April and May 2013. The study was conducted on a healthy control group, a mild chronic periodontitis group, and a moderate-to-severe chronic periodontitis group, with each comprising 100 samples. The IL-10-597(C/A) site in the promoter sequences was analyzed using the tetra-primer amplification refractory mutation system-polymerase chain reaction method to test the genotype and allele distributions. Statistical analysis was performed using Chi-squared test and ordinal classification Logistic regression analysis. RESULTS: The genotype and allele frequencies of the IL-10-597(C/A) site in the healthy control group, mild chronic periodontitis group, and moderate-to-severe chronic periodontitis group exhibited no significant difference (P>0.05). The age of all the samples was associated with chronic periodontitis. The risk of chronic periodontitis in the people of 55-65 years old was 25 times in the people under the age of 35 (OR=25.56, P<0.001). CONCLUSIONS: The IL-10-597 (C/A) single nucleotide polymorphisms in the gene promoter are not associated with chronic periodontitis in Uygur adult population. PMID- 29188650 TI - [The role of extracellular signal regulated kinase 1/2 in mediating osteodifferentiation of human periodontal ligament cells induced by cyclic stretch]. AB - OBJECTIVE: This study aimed to investigate the mechanism of cyclic stretch that promotesthe osteogenic differentiation of human periodontal ligament cells (hPDLCs) through the mediation of extracellular-signal-regulated kinase 1/2 (ERK1/2). METHODS: hPDLCs were isolated through the explant method and cultured in vitro. hPDLCs were mechanically stimulated by a multi-channel cell-stress loading system for 1, 3, 6, 12, and 24 h. The magnitude of stretch was 10% deformation, and the frequency was 0.5 Hz. Nonloaded cells were used as control group. ERK1/2 activation was blocked by U0126, a specific ERK1/2 pathway inhibitor. Additionally, hPDLCs were transfected with adenoviral vector encoding dominant negative ERK1/2 (DN-ERK1/2) to continuouslyinhibit ERK1/2 activation. The mRNA and protein levels of target geneswere detected through real-time polymerase chain reaction and Western blot. RESULTS: Cyclic stretching promoted the expression of ERK1/2, osteocalcin (OCN) mRNA, and bone sialoprotein (BSP) mRNA. The expression of runt-related transcription factor (Runx) 2 protein and mRNA also increased at 3 and 6 h of cyclic stretching. The inhibition of ERK1/2 by U0126 and DN-ERK1/2 suppressed the expressionof Runx2 mRNA, OCN mRNA, BSP mRNA, Runx 2 protein, and p-ERK1/2 protein relative to that in stretched cells without the ERK1/2 inhibitor. CONCLUSIONS: ERK1/2 is a critical molecule in the mediation ofthe osteogenic differentiation of hPDLCs under mechanical stimulation. ERK1/2 activation induced the elevation of Runx2 protein levels, which may be involved in the stretch-induced expressions of OCN and BSP. PMID- 29188651 TI - [Research progress on the relationship and mechanisms between periodontal disease and preterm birth and low-birth-weight infants]. AB - Preterm birth (PB) is defined as the birth of a baby less than 37 weeks of gestational age. Low birth weight (LBW) is defined as a newborn baby's weight of less than 2 500 g. PB is often accompanied by LBW. Preterm low birth weight (PLBW) is the leading cause of newborn deaths. Periodontal disease (PD) is a chronic oral infectious disease, and it is closely related with general health. Epidemiological data show that PD is a risk factor for PLBW and other adverse pregnancy outcomes. The possible mechanisms include the direct effects of periodontal bacteria, inflammatory reactions, and immune response; however, the exact pathogenetic mechanism involved remains controversial. This article aims to review the research progress on the relationship between PD and PLBW and their underlying mechanisms, as well as the effects of periodontal treatment on PLBW incidence.

PMID- 29188653 TI - [Research progress on the type IX secretion system of Porphyromonas gingivalis]. AB - In recent years, the study found that Porphyromonas gingivalis type IX secretion system (T9SS) is a novel protein secretion system, also known as Por secretion system (PorSS). Unlike the eight protein secretion systems found in the past, the system is a polyprotein complex found only in Bacteroides. The secreted proteins have both N- and C-terminus, where the former includes Sec-dependent type I signals peptide, and the latter contains conserved domains (C-terminal conserved domain, CTD). Porphyromonas gingivalis T9SS includes proteins such as intima, outer membrane, cytoplasm, and cell cycle, including at least 34 proteins containing CTD. Porphyromonas gingivalis T9SS is involved in regulating associated virulence factors including gingivin, fimbriae, lipopolysaccharide, HBP35, CPG70 protein and peptidyl-arginine deiminase. These CTD-containing virulence proteins are localized by T9SS and then released to the extracellular domain, thereby destroying periodontal tissue. Therefore, this review summarizes the research progress on the T9SS of Porphyromonas gingivalis. PMID- 29188654 TI - [Research progress on QMix properties in root canal irrigation]. AB - Mechanical instrumentation preparation alone is insufficient to completely remove root canal infection, and chemical irrigation is essential to eliminate infected remnants. An ideal root canal irrigant should completely remove the smear layer, lubricate the root canal, efficiently kill bacteria, induce mild or no inflammatory response in the tissues, and avoid damaging the dentin structure. However, a commercial irrigant that meets all these requirements is currently lacking. QMix is a root canal irrigation mixture of ethylenediamine tetraacetic acid (EDTA), chlorhexidine (CHX) and surfactant. This mixture can remove the smear layer efficiently, and it possesses strong antibacterial effect and good biocompatibility with minimal cytotoxicity. Furthermore, the influence of QMix on the color and micro-hardness of dentin is low, and it can improve the wettability of root canal sealant without affecting its adhesive properties. This review compares the efficiencies of QMix with other irrigants (sodium hypochlorite, CHX, EDTA, SmearClear, and MTAD) in term of smear layer removal, dentine and root canal sealing, cell cytotoxicity, and bacterial growth inhibition.

AB - Taste receptors guide individuals to consume nutrients while avoiding potentially noxious substances. Interestingly, recent studies have shown that taste receptors are also expressed beyond the taste buds, including brain, respiratory system, and digestive system, etc. These extragustatory taste receptors play important roles in microbial infection, nutrient uptake and host homeostasis. Mang extragustatory taste receptors have been proposed to sense microorganisms and regulate host innate defense. More importantly, polymorphisms of genes encoding taste receptor, particularly bitter taste receptor, are linked to different innate defensive responses. This review introduces the molecular basis of taste signal transduction, and the role of taste receptors in the regulation of innate immunity during microbial infection were further discussed in detail. PMID- 29188656 TI - [Features of condylography curves]. AB - With the kinematic face bow, the condyle movements representing temporomandibular joint function can be recorded instantly. The condylography curves can be utilized for diagnostic analysis, as different pathophysiological conditions have unique curve patterns. By tracing the specific alterations on the curves, the structural and functional statuses of the temporomandibular joint can be predicted. However, to the best of our knowledge, no standardized and practicable evaluation protocol for jaw movement tracing exists. In the current study, the features of either normal or abnormal curves were reviewed. Such features can be clinically used for determining temporomandibular joint status, thereby contributing to a comprehensive diagnosis.

AB - This study presents a case of synchronous multiple primary cancers involving floor of mouth carcinoma with esophageal carcinoma. Literature was reviewed to summarize the incidence, location, diagnosis, treatment characteristics, and prognosis to improve understanding and awareness of the multiple primary cancer. As a result, early discovery, early diagnosis, and effective treatment can help prolong survival and improve the quality of life of patients. PMID- 29188658 TI - Assessing local stromal alterations in human ovarian cancer subtypes via second harmonic generation microscopy and analysis. AB - The collagen architecture in all human ovarian cancers is substantially remodeled, where these alterations are manifested in different fiber widths, fiber patterns, and fibril size and packing. Second harmonic generation (SHG) microscopy has differentiated normal tissues from high-grade serous (HGS) tumors with high accuracy; however, the classification between low-grade serous, endometrioid, and benign tumors was less successful. We postulate this is due to known higher genetic variation in these tissues relative to HGS tumors, which are genetically similar, and this results in more heterogeneous collagen remodeling in the respective matrix. Here, we examine fiber widths and SHG emission intensity and directionality locally within images (e.g., 10*10 microns) and show that normal tissues and HGS tumors are more uniform in fiber properties as well as in fibril size and packing than the other tissues. Moreover, these distributions are in good agreement with phase matching considerations relating SHG emission directionality and intensity. The findings show that in addition to average collagen assembly properties the intrinsic heterogeneity must also be considered as another aspect of characterization. These local analyses showed differences not shown in pure intensity-based image analyses and may provide further insight into disease etiology of the different tumor subtypes. PMID- 29188659 TI - Morphometric analysis of erythrocytes from patients with thalassemia using tomographic diffractive microscopy. AB - Complete blood count is the most common test to detect anemia, but it is unable to obtain the abnormal shape of erythrocytes, which highly correlates with the hematologic function. Tomographic diffractive microscopy (TDM) is an emerging technique capable of quantifying three-dimensional (3-D) refractive index (RI) distributions of erythrocytes without labeling. TDM was used to characterize optical and morphological properties of 172 erythrocytes from healthy volunteers and 419 erythrocytes from thalassemic patients. To efficiently extract and analyze the properties of erythrocytes, we developed an adaptive region-growing method for automatically delineating erythrocytes from 3-D RI maps. The thalassemic erythrocytes not only contained lower hemoglobin content but also showed doughnut shape and significantly lower volume, surface area, effective radius, and average thickness. A multi-indices prediction model achieved perfect accuracy of diagnosing thalassemia using four features, including the optical volume, surface-area-to-volume ratio, sphericity index, and surface area. The results demonstrate the ability of TDM to provide quantitative, hematologic measurements and to assess morphological features of erythrocytes to distinguish healthy and thalassemic erythrocytes. PMID- 29188661 TI - Automatic classification of retinal three-dimensional optical coherence tomography images using principal component analysis network with composite kernels. AB - We present an automatic method, termed as the principal component analysis network with composite kernel (PCANet-CK), for the classification of three dimensional (3-D) retinal optical coherence tomography (OCT) images. Specifically, the proposed PCANet-CK method first utilizes the PCANet to automatically learn features from each B-scan of the 3-D retinal OCT images. Then, multiple kernels are separately applied to a set of very important features of the B-scans and these kernels are fused together, which can jointly exploit the correlations among features of the 3-D OCT images. Finally, the fused (composite) kernel is incorporated into an extreme learning machine for the OCT image classification. We tested our proposed algorithm on two real 3-D spectral domain OCT (SD-OCT) datasets (of normal subjects and subjects with the macular edema and age-related macular degeneration), which demonstrated its effectiveness. PMID- 29188660 TI - Multiphoton fluorescence lifetime imaging of chemotherapy distribution in solid tumors. AB - Doxorubicin is a commonly used chemotherapeutic employed to treat multiple human cancers, including numerous sarcomas and carcinomas. Furthermore, doxorubicin possesses strong fluorescent properties that make it an ideal reagent for modeling drug delivery by examining its distribution in cells and tissues. However, while doxorubicin fluorescence and lifetime have been imaged in live tissue, its behavior in archival samples that frequently result from drug and treatment studies in human and animal patients, and murine models of human cancer, has to date been largely unexplored. Here, we demonstrate imaging of doxorubicin intensity and lifetimes in archival formalin-fixed paraffin-embedded sections from mouse models of human cancer with multiphoton excitation and multiphoton fluorescence lifetime imaging microscopy (FLIM). Multiphoton excitation imaging reveals robust doxorubicin emission in tissue sections and captures spatial heterogeneity in cells and tissues. However, quantifying the amount of doxorubicin signal in distinct cell compartments, particularly the nucleus, often remains challenging due to strong signals in multiple compartments. The addition of FLIM analysis to display the spatial distribution of excited state lifetimes clearly distinguishes between signals in distinct compartments such as the cell nuclei versus cytoplasm and allows for quantification of doxorubicin signal in each compartment. Furthermore, we observed a shift in lifetime values in the nuclei of transformed cells versus nontransformed cells, suggesting a possible diagnostic role for doxorubicin lifetime imaging to distinguish normal versus transformed cells. Thus, data here demonstrate that multiphoton FLIM is a highly sensitive platform for imaging doxorubicin distribution in normal and diseased archival tissues.

AB - OBJECTIVES: To establish the imaging mass spectrometry for analysis of differentially expressed proteins distribution in the rat brains with diffuse axonal injury (DAI) based on matrix assisted laser desorption/ionization-time of flight imaging mass spectrometry (MALDI-TOF-IMS). METHODS: MALDI-TOF-IMS scanning were conducted on the brains of DAI group and control group in the m/z range of 1 000 to 20 000 using AutoflexIII MALDI-TOF spectrometer. ClinProTool 2.2 software was used for statistical analysis on the data of two groups, and then the differentially expressed proteins were picked out to conduct imaging. The distribution of the proteins with different m/z in the rat brains was observed. RESULTS: Five proteins with different m/z, including 4 963, 5 634, 6 253, 6 714 and 7 532, differentially expressed in the rat brains with DAI.

PMID- 29188663 TI - [Correlation between RNA Expression Level and Early PMI in Human Brain Tissue]. AB - OBJECTIVES: To explore the correlation between the expression levels of several RNA markers in human brain tissue and early postmortem interval (PMI). METHODS: Twelve individuals with known PMI (range from 4.3 to 22.5 h) were selected and total RNA was extracted from brain tissue. Eight commonly used RNA markers were chosen including beta-actin, GAPDH, RPS29, 18S rRNA, 5S rRNA, U6 snRNA, miRNA-9 and miRNA-125b, and the expression levels were detected in brain tissue by real time fluorescent quantitative PCR. The internal reference markers with stable expression in early PMI were screened using geNorm software and the relationship between its expression level and some relevant factors such as age, gender and cause of death were analyzed. RNA markers normalized by internal reference were inserted into the mathematic model established by previous research for PMI estimation using R software. Model quality was judged by the error rate calculated with estimated PMI. RESULTS: 5S rRNA, miRNA-9 and miRNA-125b showed quite stable expression and their expression levels had no relation with age, gender and cause of death. The error rate of estimated PMI using beta-actin was 24.6%, while GAPDH was 41.0%. CONCLUSIONS: 5S rRNA, miRNA-9 and miRNA-125b are suitable as internal reference markers of human brain tissue owing to their stable expression in early PMI. The expression level of beta-actin correlates well with PMI, which can be used as an additional index for early PMI estimation.

AB - People aged 18 years could be punished lightly or diminished criminal responsibility, even be spared the death sentence, which has important meaning in Chinese judicatory adjudication. The epiphysis of long bones from human limbs and the secondary sexual characteristics almost have developed completely before 18 years old. Clavicle epiphysis is one of the articular metaphysis which has a late epiphyseal closure. The recent studies in exploring the rule of clavicle epiphyseal by multi-imaging technology shows that the development of clavicle epiphysis has some value in age estimation of 18 years old. CT, especially thin section CT, is widely used at present. However, thin-section CT scanning has great net radiation, which is not ethically acceptable if it is not for diagnosis and treatment. MRI is nonradioactive tomographic imaging and easy to evaluate, which is one of the future research directions in forensic age estimation using the medial clavicle. This paper summarizes the progress on the rule of clavicle epiphyseal closure, and analyzes and summarizes the feasibility of rule of clavicle epiphyseal closure applies on age estimation. PMID- 29188673 TI - [Review of Second Generation Sequencing and Its Application in Forensic Genetics]. AB - The rapid development of second generation sequencing (SGS) within the past few years has led to the increasement of data throughput and read length while at the same time brought down substantially the sequencing cost. This made new breakthrough in the area of biology and ushered the forensic genetics into a new era. Based on the history of sequencing application in forensic genetics, this paper reviews the importance of sequencing technologies for genetic marker detection. The application status and potential of SGS in forensic genetics are discussed based on the already explored SGS platforms of Roche, Illumina and Life Technologies. With these platforms, DNA markers (SNP, STR), RNA markers (mRNA, microRNA) and whole mtDNA can be sequenced. However, development and validation of application kits, maturation of analysis software, connection to the existing databases and the possible ethical issues occurred with big data will be the key factors that determine whether this technology can substitute or supplement PCR CE, the mature technology, and be widely used for cases detection.

AB - Under the catalysis of a variety of metabolic enzymes in vivo, such as UDP glucuronyl transferases, cytochrome P450, carboxylesterase, sulfotransferase, butyrylcholinesterase, catechol-O-methyl transferase and 6-morphine dehydrogenase, the drugs perform glucuronidation, hydrolysis, oxidation, sulfonation and other reactions, then translate into active or inactive metabolites, which are excreted through urination, bile or the other pathways at last. Different drugs own their different metabolic pathways. This paper introduces the studies about the metabolism of drugs in human and animal in recent years, such as morphine-like drugs, amphetamine, ketamine, cannabis and cocaine, and reviews the research progress about the sites of metabolism, metabolic enzymes, metabolites and physiological activity of those drugs metabolic in vivo. PMID- 29188676 TI - Autologous lipotransfer versus stromal vascular fraction enriched lipoinjection for diabetic foot wounds healing: a pilot study. AB - Chronic ulcers of the lower limbs represent a significant social and economic burden. Diabetes is a strong risk factor for development of chronic lesions. Adult stem cells and growth factors derived from the adipose tissue are among the most promising therapeutic strategies for hard to heal wounds. Fat grafts have been used for several decades to treat soft tissue deformities, but despite its excellent characteristics, the outcome was unpredictable, due to partial necrosis and resorption of the graft. Stem cells' enrichment of these grafts or their injection into the edges of the ulcers have shown encouraging results in various experimental settings. In this pilot study, we compared the standard of care to autologous lipotransfer and stromal vascular fraction (SVF) enriched lipoinjection in 30 patients with diabetic foot ulcers, showing clear superiority of SVF enriched lipoinjection in terms of percentage of reduction of ulcers size and healing time. PMID- 29188675 TI - The Origin and Development of Medical Jurisprudence in Xiangya. AB - The origin of medical jurisprudence in China can be traced back to as early as 1920s, and since then, the discipline has undergone a great development. This paper, based on the disciplinary development of medical jurisprudence at Xiangya School of Medicine, illustrates its evolution in three aspects covering the scientific and theoretic foundation, legal system and policy support. The current investigation reflected a glimpse of the modern forensic science in China, providing useful historical reference for the development of Chinese forensic science. PMID- 29188677 TI - Scanning electron, 3D-confocal and stereotactic microscopies morpho-structural analysis of antibiotic-loaded cement porosity in three different formulations. AB - Chronic osteoarticular infections such as osteomyelitis or periprosthetic joint infection (PJI)have become a growing problem over the years. The "gold standard" in local antibiotic administration is still the antibiotic-loaded acrylic bone cement (ALABC) which is used in both prophylaxis, because it has been shown it can reduce the risk of infection and used in therapy during a "two-stage surgery" in PJI or in chronic osteomyelitis. We performed morphological analysis of three different formulations of antibiotic-loaded cement (ALABC) using techniques of light microscopy, scanning electron microscopy (SEM) and 3D immunofluorescence, in order to explain how the morphological aspects of cement could influence and modulate antibiotic elution. PMID- 29188678 TI - Posterolateral bundle reconstruction of the anterior cruciate ligament to restore rotational stability of the knee. AB - Only 5-10% of partial tears of the anterior cruciate ligament (ACL) are symptomatic, especially in high demand individuals or in patients practicing sports requiring rotational motions.. A certain preoperative diagnosis of this condition is challenging and often needs the combination of clinical examination, magnetic resonance imaging (MRI) and knee-laxity tool measurements. However, the arthroscopic examination of the torn ACL bundle is the most important factor in decision-making. Evidence in various studies have shown that the preservation of the ACL remnant and its surgical augmentation can bring important advantages in terms of vascularity and proprioception, resulting in better outcomes. The purpose of our paper was to describe the surgical technique of arthroscopic posterolateral (PL) bundle reconstruction with the preservation of the anteromedial (AM) bundle for ACL partial tears. Moreover, we reported the current knowledge about rationale, diagnosis and treatment of partial tears of ACL. PMID- 29188679 TI - A new surgical positioning system for robotic assisted minimally invasive spine surgery and transpedicular approach to the disc. AB - Minimally Invasive Spine Surgery (MISS) procedures for the treatment of spinal pathologies have experienced exponential growth due to improved techniques and decreased trauma to the patient. Several MISS procedures that require the use of a trans-pedicular cannula as a guiding tool for pedicle screw placement, delivery of biomaterials to the vertebral body or injection of biologics to the disc space have been described. Although these are clear advantages of MISS, the limited dissection and exposure may reduce the accuracy and stability of operation and make spine surgeons rely heavily on intraoperative fluoroscopy, raising concerns over the level of radiation exposure. Robot-assisted minimal invasive surgery has aroused more attention for its high precision and stability, minimizing risks of damage to neurovascular structures and diminishing harmful exposure to ionizing radiation. The aim of this paper is to describe and characterize a new surgical positioning system for for robotic assisted MISS. The system is conceived to be integrated in a surgical platform capable of supporting the surgeon in a new procedure to treat degenerative intervertebral disc disease. For this purpose, it is necessary to orientate a cannula in order to guide the bone drill along a planned route, to access the intervertebral disc through the pedicle and endplate. In particular, we describe a mechanism that percutaneously guides a cannula towards the intervertebral disc based on the acquisition of few fluoroscopic images. The design of the positioning system, with its features and constrains imposed by the presence of instrumentation and medical staff in the operating room, as well as the software for trajectory planning during surgery, are here described. PMID- 29188680 TI - Biomaterials as bone graft substitutes for spine surgery: from preclinical results to clinical study. AB - Vertebral fusion is performed in order to stabilize the spine in the presence of degenerative, traumatic or oncological pathologies that alter its stability. The autologous bone, harvested from the patient's iliac crest or from the lamina during surgery, is still considered the "gold standard" for spine fusion due to its osteogenic, osteoinductive and osteoconductive properties. However, several biological and synthetic bone substitutes have been introduced as alternatives for regenerating bone tissue. We have studied in particular the use of ceramic biomaterials prepared from hydroxypatite (HA), starting from in vitro analysis, through an in vivo study on ovine animal model and a post-market surveillance analysis, to finally design and perform a clinical study, which is ongoing in our Department. In the first step, HA-derived biomaterials were tested in vitro in the presence of bone marrow-derived human mesenchymal stem cells (hMSCs) and evaluated for their ability to activate precursor cells. In the second step, the biomimetic bone graft substitute SintLife(r) putty (MgHA) was evaluated in vivo. A posterolateral fusion procedure was applied on 18 sheep, where a fusion level was treated with MgHA, while the other level was treated with autologous bone. Microtomography and histological/histomorphometric analysis were performed six months of after surgery. In the third step, we reported the results of a post market surveillance study conducted on 4 independent cohorts of patients (total 115 patients), in which HA-derived biomaterials were used as bone graft substitutes or extenders. Finally, a clinical study has been designed and approved by the Ethics Committee of our Institute and is currently ongoing. This study aims to evaluate the efficacy of the ceramic biomaterial SintLife(r) putty for bone replacement in patients treated by posterolateral fusion for degenerative spine disorders. HA biomaterials were effective in promoting the in vitro growth of hMSCs and their osteogenic differentiation. In the animal model, SintLife(r) putty has been effective in generating neo-formed bone tissue with morphological and structural features similar to those of the pre-existing bone. The post-market surveillance analysis has not reported any intra-operative nor early or late post-operative adverse events. Seven patients are currently recruited for the clinical trial designed to evaluate Sintlife efficacy for spine fusion (FU range: 1-7 months). No adverse events have been recorded. The first CT analysis performed at 6 months FU showed a good spine fusion. The study is ongoing. Our results, obtained from in vitro, preclinical and clinical studies, suggest that biomaterials derived from hydroxyapatite could be a valid alternative to autologous bone graft for vertebral fusion. This would potentially avoid or reduce the need of autologous bone harvesting and therefore, the risk of drawback-related side effects. PMID- 29188681 TI - Targeted muscle reinnervation for improved control of myoelectric upper limb prostheses. AB - Targeted muscle reinnervation (TMR) is a novel surgical technique developed to improve the control of myoelectric upper limb prostheses. Nerves transected by the amputation, which retain their original motor pathways even after being severed, are redirected to residual denervated muscles that serve as target for consequent reinnervation. Once the process is complete, reinnervated muscles will contract upon voluntary activation of transferred nerves while attempting to move missing regions of the amputated limb, generating EMG signals that can be recorded and used to control a prosthetic device. This allows creating new control sites that can overcome major drawbacks of conventional myoelectric prostheses by offering a more natural and intuitive control of prosthetic arms. TMR has been widely performed in individuals who underwent shoulder disarticulation amputation and transhumeral amputation since proximal amputations do not leave enough functional muscles exploitable to control independent degree of freedoms of multi-articulated prostheses. TMR application is currently under investigation in patients suffering further distal amputations, as well as for treating and preventing painful post-amputation neuromas. The purpose of this paper is to describe the physiologic basis and the surgical technique of TMR, reporting current knowledge on the clinical results. PMID- 29188682 TI - Biomass growth response to spatial pattern of variable-retention harvesting in a northern Minnesota pine ecosystem. AB - Variable-retention harvesting (VRH) is an approach for sustaining complex structure in managed forests. A criticism of VRH is that ecological benefits may come at a cost of reduced growth of regeneration, due to competition with residual trees. However, the spatial pattern of retention, i.e., dispersed or aggregated, in VRH systems can be manipulated to minimize suppression of regeneration, and resource limitation to regeneration might be mitigated by reduction of woody shrubs. Continued growth of the residual cohort will compensate for growth reduction of regeneration, although this may differ with retention pattern. We examined aboveground whole-stand biomass growth of trees in a VRH experiment in Pinus resinosa forest in Minnesota, USA. Treatments included dispersed retention, aggregated retention, and an uncut control, as well as a shrub treatment (reduced density or ambient). We addressed the following hypotheses: (1) biomass growth of a cohort of planted pine seedlings will be highest with aggregated rather than dispersed retention, (2) biomass growth of the planted seedlings will increase with shrub reduction, and (3) biomass growth of the residual overstory will be higher with dispersed rather than aggregated retention. Aboveground biomass growth of the planted pines ranged from 0.4 kg.ha 1.yr-1 in the overstory-control-ambient-shrub treatment to 23 kg.ha-1.yr-1 in the aggregated-retention-shrub-reduction treatment. The difference between the control and the retention treatments was significant (P < 0.0001), but not between dispersed and aggregated retention (P = 0.97). Thus, our first hypothesis was not supported. In all treatments, biomass growth was significantly higher (>100% increase) with shrub reduction (P = 0.001), supporting our second hypothesis. Biomass growth of residual trees ranged from 2404 kg.ha-1.yr-1 in the uncut-control-ambient-shrub treatment to 1043 kg.ha-1.yr-1 in the aggregated retention-shrub-reduction treatment. Differences were significant between the control and retention treatments (P = 0.003), and marginally higher with dispersed vs. aggregated retention (P = 0.09), lending support to our third hypothesis. Our results suggest that managers have flexibility in application of VRH and can expect similar stand-level biomass growth of planted regeneration regardless of retention pattern, but somewhat higher stand-level biomass growth of retained trees with dispersed retention. PMID- 29188683 TI - Effects of forest management on California Spotted Owls: implications for reducing wildfire risk in fire-prone forests. AB - Management of many North American forests is challenged by the need to balance the potentially competing objectives of reducing risks posed by high-severity wildfires and protecting threatened species. In the Sierra Nevada, California, concern about high-severity fires has increased in recent decades but uncertainty exists over the effects of fuel-reduction treatments on species associated with older forests, such as the California Spotted Owl (Strix occidentalis occidentalis). Here, we assessed the effects of forest conditions, fuel reductions, and wildfire on a declining population of Spotted Owls in the central Sierra Nevada using 20 years of demographic data collected at 74 Spotted Owl territories. Adult survival and territory colonization probabilities were relatively high, while territory extinction probability was relatively low, especially in territories that had relatively large amounts of high canopy cover (>=70%) forest. Reproduction was negatively associated with the area of medium intensity timber harvests characteristic of proposed fuel treatments. Our results also suggested that the amount of edge between older forests and shrub/sapling vegetation and increased habitat heterogeneity may positively influence demographic rates of Spotted Owls. Finally, high-severity fire negatively influenced the probability of territory colonization. Despite correlations between owl demographic rates and several habitat variables, life stage simulation (sensitivity) analyses indicated that the amount of forest with high canopy cover was the primary driver of population growth and equilibrium occupancy at the scale of individual territories. Greater than 90% of medium intensity harvests converted high-canopy-cover forests into lower-canopy-cover vegetation classes, suggesting that landscape-scale fuel treatments in such stands could have short-term negative impacts on populations of California Spotted Owls. Moreover, high-canopy-cover forests declined by an average of 7.4% across territories during our study, suggesting that habitat loss could have contributed to declines in abundance and territory occupancy. We recommend that managers consider the existing amount and spatial distribution of high-canopy forest before implementing fuel treatments within an owl territory, and that treatments be accompanied by a rigorous monitoring program. PMID- 29188684 TI - Pattern recognition in long-term Sooty Shearwater data: applying machine learning to create a harvest index. AB - Rakiura Maori (New Zealand's southernmost group of indigenous peoples) have harvested the chicks of burrow-nesting Sooty Shearwaters (Titi; Puffinus griseus) for generations. As part of the harvest process, some families have maintained annual harvest diaries, some dating back to the 1950s. We used generalized boosted regression models, a machine-learning algorithm, to calculate a harvest index that takes into account factors that could impact the numbers of birds taken on any given hunt. For predicted vs. observed values, r2 was between 0.59 and 0.90 for the nanao (first half of the season, when chicks are harvested from burrows during the day) and 0.67 and 0.88 for the rama (second half of the season, during which chicks are harvested from the surface at night). Exploration of the controlling factors of the models revealed that "day of season" plays an important role in predicting daily harvest during the second half of the season (the rama). The nightly tally in the rama peaked approximately halfway through (10-15 days in), which is probably related to the timing of birds emerging from burrows to fledge. The models also suggested that data from the rama (when chicks are 100-120 days old) may be the most suitable for long-term monitoring of populations of Sooty Shearwaters due to consistencies in calculated harvest indices between diaries. Nanao harvest indices, although less consistent, showed patterns similar to those of the rama. When comparing these data to the harvest indices calculated by general linear models by Clucas and colleagues, we found that the agreement between both indices was r2 = 0.31 and r2 = 0.59 for the nanao and rama, respectively. The use of machine learning to correct for extraneous factors (e.g., hunting effort, skill level, or weather) and to create standardized measures could be applied to other systems such as fisheries or terrestrial resource management. PMID- 29188685 TI - Functional connectivity experiments reflect routine movement behavior of a tropical hummingbird species. AB - Translocation experiments, in which researchers displace animals and then monitor their movements to return home, are commonly used as tools to assess functional connectivity of fragmented landscapes. Such experiments are purported to have important advantages of being time efficient and of standardizing "motivation" to move across individuals. Yet, we lack tests of whether movement behavior of translocated birds reflects natural behavior of unmanipulated birds. We compared the routine movement behavior of a tropical hummingbird, the Green Hermit (Phaethornis guy), to that of experimentally translocated individuals. We tested for differences in site selection patterns during movement at two spatial scales (point and path levels). We also compared movement rates between treatments. Behaviors documented during translocation experiments reflected those observed during routine movements. At the point level, both translocated and non translocated birds showed similar levels of preference for mature tropical forest. At the path level, step selection functions showed both translocated and non-translocated hummingbirds avoiding movement across non-forested matrix and selecting streams as movement corridors. Movement rates were generally higher during translocation experiments. However, the negative influence of forest cover on movement rates was proportionately similar in translocation and routine movement treatments. We report the first evidence showing that movement behavior of birds during translocation experiments is similar to their natural movement behavior. Therefore, translocation experiments may be reliable tools to address effects of landscape structure on animal movement. We observed consistent selection of landscape elements between translocated and non-translocated birds, indicating that both routine and translocation movement studies lead to similar conclusions regarding the effect of landscape structure and forest composition on functional connectivity. Our observation that hummingbirds avoid non-forest matrix and select riparian corridors also provides a potential mechanism for pollen limitation in fragmented tropical forest. PMID- 29188686 TI - Having our yards and sharing them too: the collective effects of yards on native bird species in an urban landscape. AB - Residential yards comprise a substantial portion of urban landscapes, and the collective effects of the management of many individual yards may "scale up" to affect urban biodiversity. We conducted bird surveys and social surveys in Chicago-area (Illinois, USA) residential neighborhoods to identify the relative importance of yard design and management activities for native birds. We found that groups of neighboring yards, in the aggregate, were more important for native bird species richness than environmental characteristics at the neighborhood or landscape scale. The ratio of evergreen to deciduous trees in yards and the percentage of yards with trees and plants with fruits or berries were positively associated with native bird species richness, whereas the number of outdoor cats had a negative association. The number of birdfeeders was not an important predictor for native species richness. We also found that migratory birds were observed on transects with more wildlife-friendly features in yards, and nonnative birds were observed on transects with greater numbers of outdoor cats and dogs. Our results highlight the potential importance of residential matrix management as a conservation strategy in urban areas. PMID- 29188687 TI - Population models for social species: lessons learned from models of Red-cockaded Woodpeckers (Picoides borealis). AB - Behavior can have major impacts on the population dynamics of social species and should be incorporated into demographic models to realistically evaluate population trends and extinction risk. We compared the predictions of a stage- and age-based matrix model, an individual-based model (IBM, developed in the program Vortex), and a spatially explicit individual-based model (SEPM) with the actual dynamics of a population of Red-cockaded Woodpeckers (RCW; Picoides borealis) in the Sandhills of North Carolina, USA. Predictions, including population size, composition, and growth rate, differed the most from actual population characteristics for models that did not incorporate social structure. The SEPM most closely predicted actual population dynamics, underestimating the population by 2.3%. This model, specifically developed to simulate RCW population dynamics, contains many of the features that we assert are important for adequately incorporating social behavior into demographic and population modeling. These features include the ability to (1) differentiate individuals based on their stage class, (2) capture the dynamics of the population at both the individual and group level, (3) incorporate the positive or negative effects of subdominants, (4) include environmental and demographic stochasticity, and (5) capture dispersal and other spatial factors. The RCW SEPM, although currently species-specific, provides a strong blueprint for how population models for social species could be constructed in the future when data allow. PMID- 29188689 TI - 'Two sisters' again. PMID- 29188688 TI - Cultivation can increase harvesting pressure on overexploited plant populations. AB - Captive breeding and cultivation of overharvested species is frequently proposed as a conservation strategy, yet there is little evidence under what conditions, if at all, the strategy is effective. We created a bioeconomic model to investigate the socioeconomic conditions favoring cultivation over wild harvesting and likely impacts on the wild population. We parameterize the model with the case study of illegal xate palm (Chamaedorea ernesti-augusti) harvesting in Belize and Guatemala. We examine how changes in law enforcement, a price premium for cultivated leaf, land ownership, and alternative income might affect decisions to cultivate and the impact of cultivation on wild populations. We show that those switching to cultivation are largely not wild harvesters because of barriers such as land ownership. We also find that if harvesters do switch to cultivation, they may have a negative effect on the wild population through harvesting of material to set up plantations. We found increasing alternative income reduces harvesting pressure and suggests the provision of alternative livelihoods would more directly reduce pressure on the wild population. Although schemes to encourage cultivation seem an appealing conservation intervention, we urge caution in assuming that people will readily adopt cultivation of wild harvested species or that this would necessarily reduce impacts on wild populations.

PMID- 29188694 TI - Supra-Therapeutic Oral Paracetamol Overdose in Adults: An Update for the Dental Team. AB - Paracetamol (acetaminophen) is a commonly used analgesic; its 'over the counter' availability, low cost and popularity amongst patients often make it the first choice for dental pain. It is in this that its potential toxicity, made more complicated by the ever extending range of paracetamol-containing products, make the understanding of this medication key to the safe management of patients presenting to surgery with dental pain.

Consideration is given to those patients who can be treated safely in primary care and to those who require transfer to Accident and Emergency (A&E). PMID- 29188695 TI - An Implant-Retained Obturator - A Case Study. AB - This case describes the oral rehabilitation of a patient following maxillary hemi section due to squamous cell carcinoma of the palate. Planned treatment was construction of a maxillary implant-supported obturator. Two dental implants were placed in his maxilla to aid the support and retention of an obturator. However, owing to bone availability, their angulation was suboptimal and compromised the retention of the obturator. This case describes alternative implant attachments to aid the retention and stability of implant-retained dentures constructed in cases with suboptimal implant placement. Clinical relevance: This case highlights the importance of careful planning for implant placement, and reinforces the need to plan the prostheses before implant surgery. This case highlights possible difficulties that can arise if implants are non-ideally angulated, and how to adapt restorations to manage such difficulties in cases with maxillary removable prostheses.

The purpose of this article is to determine the applicability of VRET in the treatment of dental phobia of two patients. Two case examples of female dental patients, aged 56 and 24 years, who met the criteria for dental phobia according to the Phobia Checklist, illustrate the use of VRET in the dental setting. VRET that is used as a psychological treatment for dental fear and dental phobia can potentially be given by a non-specialist (for example dental assistant), thereby making it a cost-effective therapy for the treatment of dental phobia.Clinical relevance: This article is the first of its kind to demonstrate Virtual Reality Exposure Therapy (VRET) in the treatment of dental anxiety. PMID- 29188697 TI - The Immune System: Basis of so much Health and Disease: 4. Immunocytes. AB - The immune system is the body's primary defence mechanism against infections, and disturbances in the system can cause disease if the system fails in defence functions (in immunocompromised people), or if the activity is detrimental to the host (as in auto-immune and auto-inflammatory states). A healthy immune system is also essential to normal health of dental and oral tissues. This series presents the basics for the understanding of the immune system, this article covers cells of the immune system (immunocytes). Clinical relevance: Modern dental clinicians need a basic understanding of the immune system as it underlies health and disease.

PMID- 29188699 TI - Ceramic Fracture in Metal-Ceramic Restorations: The Aetiology. AB - All dental restorations are liable to failure during function. Failure could be biologic, aesthetic, mechanical or a combination. Ceramic restorations in particular, including metal-ceramics, are prone to mechanical fracture, especially the fracture of veneering porcelain. Fracture of a metal-ceramic restoration jeopardizes function as well as aesthetics. It is equally onerous to manage for both patient and dentist. Optimal management of such cases requires a detailed knowledge of the aetiology behind this phenomenon. The current paper aims to highlight possible causative factors involved in the mechanical failures of metal-ceramic restorations. Clinical relevance: Ceramic fracture in metal ceramic crowns and fixed partial dentures is routinely encountered in dental clinics. Knowledge of the aetiology is required to diagnose and manage such cases accurately as well as to avoid these errors in future.

AB - Periodontal plastic and aesthetic surgery are gaining significant momentum owing to the increasing aesthetic demands by patients. Along with the fulfilment of aesthetic needs, it is imperative that clinicians also enhance function. From these two important viewpoints, subepithelial connective tissue grafting remains an optimum treatment choice for periodontists when treating gingival recession defects accompanied by periodontal attachment apparatus breakdown. Clinical relevance: Subepithelial connective tissue grafting is a successful procedure in its dual role of gingival recession coverage and predictable periodontal regeneration.

AB - The incidence of small nephromas of less than four centimeters in size has increased over the past decades with the increasing number of imaging studies. The majority of these tumors are kidney cancers exhibiting large variation in their aggressiveness. Systematic surgical treatment of these tumors results in more harm than benefit especially for elderly patients having associated diseases. Biopsy procedures from tumors by current methods are safe. The challenge of active surveillance is to identify those nephromas that are no longer safely monitored before the cancer is beyond the reach of curative treatment. PMID- 29188705 TI - Individualized methods for the diagnosis and treatment of nonspecific lower back pain. AB - Lower back pain is globally the most common problem interfering with functional capacity, and the recognition of causes that are serious and require specific therapy is essential in its diagnosis. Provision of information for a person suffering from lower back pain is essential. In some patients psychosocial factors prolong the back pain and potential incapacity for work. For their evaluation several internationally validated surveys have been developed, which can be used to facilitate the identification of higher-risk patients. By using electronic data, our aim is to develop in Finland the assessment of individual risk of patients with lower back pain and their appropriate treatment. PMID- 29188706 TI - Highly Stretchable and Transparent Electromagnetic Interference Shielding Film Based on Silver Nanowire Percolation Network for Wearable Electronics Applications. AB - Future electronics are expected to develop into wearable forms, and an adequate stretchability is required for the forthcoming wearable electronics considering various motions occurring in human body. Along with stretchability, transparency can increase both the functionality and esthetic features in future wearable electronics. In this study, we demonstrate, for the first time, a highly stretchable and transparent electromagnetic interference shielding layer for wearable electronic applications with silver nanowire percolation network on elastic poly(dimethylsiloxane) substrate. The proposed stretchable and transparent electromagnetic interference shielding layer shows a high electromagnetic wave shielding effectiveness even under a high tensile strain condition. It is expected for the silver nanowire percolation network-based electromagnetic interference shielding layer to be beyond the conventional electromagnetic interference shielding materials and to broaden its application range to various fields that require optical transparency or nonplanar surface environment, such as biological system, human skin, and wearable electronics. PMID- 29188707 TI - Increasing Extracellular Free Fatty Acid Production in Escherichia coli by Disrupting Membrane Transport Systems. AB - Transposon mutagenesis was used to identify three mutants of E. coli that exhibited increased free fatty acid (FFA) production, which resulted from the disruption of genes related to membrane transport. Deletion of envR, gusC, and mdlA individually in a recombinant E. coli strain resulted in 1.4-, 1.8-, and 1.2 fold increases in total FFA production, respectively. In particular, deletion of envR increased the percentage of extracellular FFA to 46%, compared with 29% for the control strain. Multiple deletion of envR, gusC, mdlA, ompF, and fadL had a synergistic effect on FFA production, resulting in high extracellular FFA production, comprising up to 50% of total FFA production. This study has identified new membrane proteins involved in FFA production and showed that genetic engineering targeting these membrane transporters is important to increase both total FFA and extracellular FFA production. PMID- 29188708 TI - Role of Polymer Segregation on the Mechanical Behavior of All-Polymer Solar Cell Active Layers. AB - An all-polymer bulk heterojunction (BHJ) active layer that removes the use of commonly used small molecule electron acceptors is a promising approach to improve the thermomechanical behavior of organic solar cells. However, there has been limited research on their mechanical properties. Here, we report on the mechanical behavior of high-performance blade-coated all-polymer BHJ films cast using eco-friendly solvents. The mechanical properties considered include the elastic modulus, crack onset strain, and cohesive fracture energy. We show that the mechanical behavior of the blend is largely unaffected by significant changes in the segregation characteristics of the polymers, which was varied systematically through solvent formulation. In comparison to a polymer:fullerene BHJ counterpart, the all-polymer films were found to have lower stiffness and increased ductility. Yet, the fracture energy of the all-polymer films is not significantly improved compared to that of the polymer:fullerene films. This study highlights that improved mechanical behavior of all-polymer systems cannot be assumed, and that details of the molecular structure, molecular weight, and film morphology play an important role in both the optoelectronic and mechanical properties. Furthermore, we show that simple composite modeling provides a predictive tool for the mechanical properties of the polymer blend films, providing a framework to guide future optimization of the mechanical behavior. PMID- 29188709 TI - High-Antifouling Polymer Brush Coatings on Nonpolar Surfaces via Adsorption-Cross Linking Strategy. AB - A new "adsorption-cross-linking" technology is presented to generate a highly dense polymer brush coating on various nonpolar substrates, including the most inert and low-energy surfaces of poly(dimethylsiloxane) and poly(tetrafluoroethylene). This prospective surface modification strategy is based on a tailored bifunctional amphiphilic block copolymer with benzophenone units as the hydrophobic anchor/chemical cross-linker and terminal azide groups for in situ postmodification. The resulting polymer brushes exhibited long-term and ultralow protein adsorption and cell adhesion benefiting from the high density and high hydration ability of polyglycerol blocks. The presented antifouling brushes provided a highly stable and robust bioinert background for biospecific adsorption of desired proteins and bacteria after secondary modification with bioactive ligands, e.g., mannose for selective ConA and Escherichia coli binding.

PMID- 29188711 TI - Tracking the Source of Carbon Dot Photoluminescence: Aromatic Domains versus Molecular Fluorophores. AB - Carbon dots (CDs) are an intriguing fluorescent material; however, due to a plethora of synthesis techniques and precursor materials, there is still significant debate on their structure and the origin of their optical properties. The two most prevalent mechanisms to explain them are based on polycyclic aromatic hydrocarbon domains and small molecular fluorophores, for instance, citrazinic acid. Yet, how these form and whether they can exist simultaneously is still under study. To address this, we vary the hydrothermal synthesis time of CDs obtained from citric acid and ethylenediamine and show that in the initial phase molecular fluorophores, likely 2-pyridone derivatives, account for the blue luminescence of the dots. However, over time, while the overall size of the CDs does not change, aromatic domains form and grow, resulting in a second, faster decay channel at similar wavelengths and also creating additional lower energetic states. Electrophoresis provides further evidence that the ensemble of CDs consists of several subsets with different internal structure and surface charge. The understanding of the formation mechanism enables a control of the chemical origin of these emitters and the ensuing optical properties of the CDs through synthetic means. PMID- 29188712 TI - Direct Wittig Olefination of Alcohols. AB - A base-promoted transition metal-free approach to substituted alkenes using alcohols under aerobic conditions using air as the inexpensive and clean oxidant is described. Aldehydes are relatively difficult to handle compared to corresponding alcohols due to their volatility and penchant to polymerize and autoxidize. Wittig ylides are easily oxidized to aldehydes and consequently form homo-olefination products. By the strategy of simultaneously in situ generation of ylides and aldehydes, for the first time, alcohols are directly transferred to olefins with no need of prepreparation of either aldehydes or ylides. Thus, the di/monocontrollable olefination of diols is accomplished. This synthetically practical method has been applied in the gram-scale synthesis of pharmaceuticals, such as DMU-212 and resveratrol from alcohols. PMID- 29188713 TI - Mining for Small Translated ORFs. AB - Peptides encoded by short open reading frames (sORFs) are usually defined as peptides <=100 aa long. Usually sORFs were ignored by automatic genome annotation programs due to the high probability of false discovery. However, improved computational tools along with a high-throughput RIBO-seq approach identified a myriad of translated sORFs. Their importance becomes evident as we are gaining experimental validation of their diverse cellular functions. This Review examines various computational and experimental approaches of sORFs identification as well as provides the summary of our current knowledge of their functional roles in cells. PMID- 29188714 TI - Secoheliosphanes A and B and Secoheliospholane A, Three Diterpenoids with Unusual seco-Jatrophane and seco-Jatropholane Skeletons from Euphorbia helioscopia. AB - Secoheliosphanes A (1) and B (2) and secoheliospholane A (3), possessing an unusual 7,8-seco-jatrophane skeleton and an unprecedented 9,10-seco-7,10 epoxyjatropholane skeleton, respectively, were isolated from the whole plants of Euphorbia helioscopia, along with two biogenetically precursors, a new jatrophane diterpene, 2-epi-euphornin I (4) and a known jatrophane diterpene, euphoscopin A (5). Structures of 1-4 including absolute configurations were elucidated on the basis of spectroscopic data, X-ray crystallography, and chemical conversion. Compounds 1 and 2 were prepared from 4 and 5, respectively, confirming their structural assignments. Notably, 1 and 2 presented the first examples of seco jatrophane-type diterpenoids and 3 featured a novel 5/6/7/7-fused tetracyclic ring skeleton. Among them, compound 2 showed modest activity against HSV-1 with IC50 value of 6.41 MUM. PMID- 29188715 TI - Strain-Gradient Effect in Gas Sensors Based on Three-Dimensional Hollow Molybdenum Disulfide Nanoflakes. AB - A novel three-dimensional transition metal dichalcogenide (TMD) structure consisting of seamless hollow nanoflakes on two-dimensional basal layers was synthesized by a one-step chemical vapor deposition method. Here, we demonstrate that the as-grown nanoflakes are formed on an organic promoter layer which served as a positive template and are swollen at the grain boundaries by the bubbling effect. TMD nanosheets with hollow nanoflakes are successfully applied as chemical sensors, and it was found that their gas adsorption property is strongly related to the internal strain gradient resulting from the variation in the lattice parameter. This result is consistent with the theoretical prediction in previous studies. Our chemical vapor deposition-based approach is an efficient way to generate TMD-based nanostructures over a large surface area for various practical applications such as chemical sensors. PMID- 29188716 TI - Hybrid Organic/Inorganic Perovskite-Polymer Nanocomposites: Toward the Enhancement of Structural and Electrical Properties. AB - Hybrid organic/inorganic perovskite nanoparticles (NPs) have garnered remarkable research attention because of their promising photophysical properties. New and interesting properties emerge after combining perovskite NPs with semiconducting materials. Here, we report the synthesis and investigation of a composite material obtained by mixing CH3NH3PbBr3 nanocrystals with the semiconducting polymer poly(3-hexylthiophene) (P3HT). By the combination of structural techniques and optical and magnetic spectroscopies we observed multiple effects of the perovskite NPs on the P3HT: (i) an enlargement of P3HT crystalline domains, (ii) a strong p-doping of the P3HT, and (iii) an enhancement of interchain order typical of H-aggregates. These observations open a new avenue toward innovative perovskite NP-based applications. PMID- 29188717 TI - A Protective Role for Triacylglycerols during Apoptosis. AB - Triacylglycerols (TAGs) are one of the major constituents of the glycerolipid family. Their main role in cells is to store excess fatty acids, and they are mostly found within lipid droplets. TAGs contain acyl chains that vary in length and degree of unsaturation, resulting in hundreds of chemically distinct species. We have previously reported that TAGs containing polyunsaturated fatty acyl chains (PUFA-TAGs) accumulate via activation of diacylglycerol acyltransferases during apoptosis. In this work, we show that accumulation of PUFA-TAGs is a general phenomenon during this process. We further show that the accumulated PUFA TAGs are stored in lipid droplets. Because membrane-residing PUFA phospholipids can undergo oxidation and form reactive species under increased levels of oxidative stress, we hypothesized that incorporation of PUFAs into PUFA-TAGs and their localization within lipid droplets during apoptosis limit the toxicity during this process. Indeed, exogenous delivery of a polyunsaturated fatty acid resulted in a profound accumulation of PUFA phospholipids and rendered cells more sensitive to oxidative stress, causing reduced viability. Overall, our results support the concept that activation of TAG biosynthesis protects cells from lipid peroxide-induced membrane damage under increased levels of oxidative stress during apoptosis. As such, targeting triacylglycerol biosynthesis in cancer cells might represent a new approach to promoting cell death during apoptosis. PMID- 29188718 TI - Polyplex Micelles with Phenylboronate/Gluconamide Cross-Linking in the Core Exerting Promoted Gene Transfection through Spatiotemporal Responsivity to Intracellular pH and ATP Concentration. AB - Polyplexes as gene delivery carriers require integrated functionalities to modulate intracellular trafficking for efficient gene transfection. Herein, we developed plasmid DNA (pDNA)-loaded polyplex micelles (PMs) from poly(ethylene glycol)-based block catiomers derivatized with 4-carboxy-3-fluorophenylboronic acid (FPBA) and d-gluconamide to form pH- and ATP-responsive cross-linking in the core. These PMs exhibited robustness in the extracellular milieu and smooth endosomal escape after cellular uptake, and they facilitated pDNA decondensation triggered by increased ATP concentration inside of the cell. Laser confocal microscopic observation revealed that FPBA installation enhanced the endosomal escapability of the PMs; presumably, this effect resulted from the facilitated endo-/lysosomal membrane disruption triggered by the released block catiomers with hydrophobic FPBA moieties in the side chain from the PM at lower pH condition of endo-/lysosomes. Furthermore, the profile of intracellular pDNA decondensation from the PMs was monitored using Forster resonance energy transfer measurement by flow cytometry; these observations confirmed that PMs optimized for ATP-responsivity exerted effective intracellular decondensation of loaded pDNA to attain promoted gene transfection. PMID- 29188719 TI - Improved Carrier Transport in Perovskite Solar Cells Probed by Femtosecond Transient Absorption Spectroscopy. AB - CH3NH3PbI3 perovskite thin films have been deposited on glass/indium tin oxide/hole transport layer (HTL) substrates, utilizing two different materials as the HTLs. In the first configuration, the super hydrophilic polymer poly(3,4 ethylenedioxythiophene)-poly(styrenesulfonate), known as PEDOT:PSS, was employed as the HTL material, whereas in the second case, the nonwetting poly(triarylamine) semiconductor polymer, known as PTAA, was used. It was found that when PTAA is used as the HTL material, the averaged power conversion efficiency (PCE) of the perovskite solar cells (PSCs) remarkably increases from 12.60 to 15.67%. To explore the mechanism behind this enhancement, the aforementioned perovskite/HTL arrangements were investigated by time-resolved transient absorption spectroscopy (TAS) performed under inert conditions. By means of TAS, the charge transfer, carrier trapping, and hole injection dynamics from the photoexcited perovskite layers to the HTL can be directly monitored via the characteristic bleaching profile of the perovskite at ~750 nm. TAS studies revealed faster relaxation times and decay dynamics when the PTAA polymer is employed, which potentially account for the enhanced PCE observed. The TAS results are correlated with the structure and crystalline quality of the corresponding perovskite films, investigated by scanning electron microscopy, X ray diffraction, atomic force microscopy, micro-photoluminescence, and transmittance spectroscopy. It is concluded that TAS is a benchmark technique for the understanding of the carrier transport mechanisms in PSCs and constitutes a figure-of-merit tool toward their efficiency improvement. PMID- 29188720 TI - Surface Reactivity of Li2MnO3: First-Principles and Experimental Study. AB - This article deals with the surface reactivity of (001)-oriented Li2MnO3 crystals investigated from a multitechnique approach combining material synthesis, X-ray photoemission spectroscopy (XPS), scanning electron microscopy, Auger electron spectroscopy, and first-principles calculations. Li2MnO3 is considered as a model compound suitable to go further in the understanding of the role of tetravalent manganese atoms in the surface reactivity of layered lithium oxides. The knowledge of the surface properties of such materials is essential to understand the mechanisms involved in parasitic phenomena responsible for early aging or poor storage performances of lithium-ion batteries. The surface reactivity was probed through the adsorption of SO2 gas molecules on large Li2MnO3 crystals to be able to focus the XPS beam on the top of the (001) surface. A chemical mapping and XPS characterization of the material before and after SO2 adsorption show in particular that the adsorption is homogeneous at the micro- and nanoscale and involves Mn reduction, whereas first-principles calculations on a slab model of the surface allow us to conclude that the most energetically favorable species formed is a sulfate with charge transfer implying reduction of Mn. PMID- 29188721 TI - Comparison of major bleeding risk in patients with non-valvular atrial fibrillation receiving direct oral anticoagulants in the real-world setting: a network meta-analysis. AB - OBJECTIVE: To conduct a systematic literature review (SLR) and network meta analysis (NMA) of real-world studies comparing major bleeding risk among patients with non-valvular atrial fibrillation (NVAF) on direct oral anticoagulants (DOACs) or warfarin. METHODS: Systematic searches were conducted in MEDLINE and Embase for full-text articles published between January 1, 2003 and March 18, 2017. Eligible studies compared at least two of the following in a real-world setting: warfarin, apixaban, dabigatran, rivaroxaban, or edoxaban. A Bayesian NMA was conducted to estimate hazard ratios (HRs) for major bleeding using a random effects model. RESULTS: Eleven studies were included in the NMA. Nine studies included DOACs vs Warfarin comparisons, and four studies included DOACs vs DOACs comparisons (two studies included both comparisons). Median follow-up duration ranged from 2.6-31.2 months. No evidence was identified for edoxaban. Apixaban was associated with a significantly lower risk of major bleeding compared to other oral anticoagulants (warfarin HR = 0.58; 95% credible interval [CrI] = 0.48 0.69; dabigatran = 0.73; 0.61-0.87; rivaroxaban = 0.55; 0.46-0.66). Dabigatran was associated with a significantly lower risk than warfarin (0.79; 0.71-0.88) and rivaroxaban (0.76; 0.67-0.85), and rivaroxaban was not statistically different from warfarin (1.05; 0.91-1.19). Sensitivity analyses with standard dose and sponsorship showed consistent results. CONCLUSION: DOACs were associated with lower or similar risk of major bleeding compared with warfarin in NVAF patients. Apixaban was associated with a significantly lower risk of major bleeding than other DOACs. Dabigatran was associated with a significantly lower risk of major bleeding compared to rivaroxaban and warfarin.

AB - Three new sesquiterpenes, methyl 4-isopropyl-7-methoxy-6-methylnaphthalene-1 carboxylate (1), methyl 2-hydroxy-4-isopropyl-7-methoxy-6-methylnaphthalene-1 carboxylate (2), and methyl 2-hydroxy-6-(hydroxymethyl)-4-isopropyl-7 methoxynaphthalene-1-carboxylate (3), together with three known sesquiterpenes (4 6), were isolated from the stems of Nicotiana tabacum. Their structures were determined by means of HRESIMS and extensive 1D and 2D NMR spectroscopic studies. The results showed that compounds 2, 3, and 5 exhibited high anti-TMV activity with inhibition rates of 33.6, 35.8, and 36.7%. Compounds 1-6 showed weak inhibitory activities against some tested human tumor cell lines (NB4, A549, SHSY5Y, PC3, and MCF7) with IC50 values in the range of 6.7-9.6 MUM.

AB - AIM: This study evaluated a grade-integrated American Joint Committee on Cancer (AJCC) staging system for non-small-cell lung cancer. PATIENTS & METHODS: Surveillance, Epidemiology and End Results database was queried through SEER*Stat program. Through recursive partitioning analysis and subsequent decision-tree formation, suggested grade-modified stages were formulated. RESULTS: All pairwise hazard ratio comparisons among AJCC eighth stages were significant (p < 0.05) except stage IIIB versus stage IIIC; while all pairwise hazard ratio comparisons among modified AJCC stages were significant (p < 0.05). When stratified by histology, there was a benefit for the modified system among adenocarcinoma rather than squamous cell carcinoma patients. CONCLUSION: Grade integration improved the prognostication of the AJCC staging system particularly for stage III adenocarcinoma. This should be considered in future revisions of the AJCC staging system. PMID- 29188725 TI - Trial-Based Functional Analysis Informs Treatment for Vocal Scripting. AB - Research on trial-based functional analysis has primarily focused on socially maintained challenging behaviors. However, procedural modifications may be necessary to clarify ambiguous assessment results. The purposes of this study were to evaluate the utility of iterative modifications to trial-based functional analysis on the identification of putative reinforcement and subsequent treatment for vocal scripting. For all participants, modifications to the trial-based functional analysis identified a primary function of automatic reinforcement. The structure of the trial-based format led to identification of social attention as an abolishing operation for vocal scripting. A noncontingent attention treatment was evaluated using withdrawal designs for each participant. This noncontingent attention treatment resulted in near zero levels of vocal scripting for all participants. Implications for research and practice are presented. PMID- 29188726 TI - Smoking to fit a stigmatised identity? A qualitative study of marginalised young people in Australia. AB - In countries with comprehensive tobacco control, smoking is increasingly denormalised, with smokers subject to social stigmatisation. Qualitative research and commentary about denormalisation and stigma has largely focused on the impact on current or former smokers. Little attention has been given to the interaction between existing stigma among socially marginalised and disadvantaged young people and its role in smoking uptake, maintenance and resistance to quitting, or remaining a non-smoker. This article draws on a qualitative (grounded theory) study of young people aged 16-25 years who attended social services for at-risk youth in an inner city area in Australia, to explore the intersection between stigmatised identity and smoking in a context of increasing smoking denormalisation. Drawing on theoretical conceptualisations of stigma, we outline processes by which participants accept and apply social labels, internalise or distance themselves from stigmatised identities, and the influence of labelling on smoking trajectories, to demonstrate how the persistent dilemma of stigma shapes and reinforces smoking behaviour. The study highlights the need for tobacco control initiatives to align and integrate with broader initiatives to address structural inequality and social disadvantage. PMID- 29188727 TI - The optimal treatment of metastatic hormone-naive prostate cancer: abiraterone acetate or docetaxel? AB - AIM: To determine whether abiraterone acetate or docetaxel should be regarded as the current standard of care for metastatic hormone-naive prostate cancer (mHNPC). METHODS & MATERIALS: A network meta-analysis (NMA) using the frequentist approach and generalized pairwise modeling was computed. RESULTS: The results of this NMA favored abiraterone acetate over docetaxel-based regimens (hazard ratio: 0.79; 95% CI: 0.64-0.99) in patients with mHNPC. The results also suggest a reconsideration of the role of prednisone in view of the absence of a survival benefit (hazard ratio: 0.98; 95% CI: 0.59-1.65) with its use. CONCLUSION: Despite the paucity of direct comparative evidence, the results of this NMA favor the use of abiraterone acetate in the first-line treatment of mHNPC.

PMID- 29188729 TI - Aspiration as a Function of Age, Sex, Liquid Type, Bolus Volume, and Bolus Delivery Across the Healthy Adult Life Span. AB - OBJECTIVES: The purpose of this investigation was to examine, via flexible endoscopic evaluation of swallowing (FEES), factors that affect penetration and aspiration during swallowing across the adult lifespan. METHODS: Healthy adults (N = 203) across the third to ninth decades of life participated. Penetration Aspiration Scale (PAS) scores were assessed during FEES as a function of age, sex, liquid type (water and skim, 2%, and whole milk), volume (5, 10, 15, and 20 ml), and delivery (cup and straw). RESULTS: The PAS scores differed significantly by liquid type ( P < .0001) and age group ( P < .0001). In general, PAS scores were higher for milk versus water swallows and for older age groups. Significant interactions of liquid type by age ( P = .0042) and sex by volume ( P = .020) were also evidenced. In addition, the odds of penetration and aspiration increased significantly with milks compared to water and age ( P < .05). Increased bolus volume also increased the odds of aspiration ( P < .05). CONCLUSIONS: Aspiration may be an underappreciated phenomenon in healthy adults. The inclusion of both water and milk test boluses of various volumes during FEES may be important for the appropriate assessment of adult penetration and aspiration. PMID- 29188730 TI - Experiences of loss and relationship quality in couples living with dementia. AB - Couples living with dementia face multiple losses in their relationship, and may experience changes in their overall sense of relationship quality. These topics have predominantly been researched from the caring partner's perspective therefore, this study aimed to explore how couples adapt to relational losses to maintain quality in their relationship from the perspective of both partners. Using a constructivist grounded theory approach 10 spousal dyads, where one partner has a diagnosis of dementia, engaged in a joint interview. The results revealed three master themes: consolidating us, contextual positioning, and living well together, as well as an overarching theme of 'turning to and away'. The findings are discussed in relation to theories of loss and family adaptation, and implications for clinical practice and future research are proposed. PMID- 29188731 TI - Quality nursing care in dementia specific care units: A scoping review. AB - : Background The concept of quality nursing care in a dementia specific unit is perceived as being subject to the interpretation of individuals, nurses and healthcare organisations. As the number of dementia diagnoses increases, understanding what constitutes quality nursing care within dementia specific care units is vital to inform policy makers and healthcare organisations globally. Efforts to identify quality nursing care and improve dementia care within dementia specific care units, may significantly reduce the financial and emotional burden of care-giving and improve the quality of life for individuals living with dementia. This scoping review aimed to examine current literature to gain an understanding of what constitutes quality nursing care in a dementia specific care unit. Design and methods Five electronic databases (CINAHL, MEDLINE, ProQuest, Social Sciences Citation Index and Ovid) were used to search for articles published in English between 2011 and 2016 focusing on a definition of quality nursing care within dementia specific care units. FINDINGS: Twenty journal articles were identified. From these articles, two content themes were identified: Challenges in the provision of quality nursing care in dementia specific care units, and Standardised approach to quality nursing care in a dementia specific care unit. The articles contained the following research designs, controlled pre-test and post-test design ( n = 1), focus group interviews ( n = 1), cross sectional survey ( n = 6), semi structured interviews ( n = 3), narrative review ( n = 1), survey ( n = 2), literature review ( n = 3), systematic review ( n = 1), and prospective longitudinal cohort study ( n = 2). Conclusions The concept of quality nursing care in a dementia specific unit remains subject to the interpretation of individuals, nurses and healthcare organisations, with current literature unable to provide a clear definition. Further research into what constitutes quality nursing care in dementia specific care units is recommended. PMID- 29188732 TI - Parolee-Parole Officer Rapport: Does It Impact Recidivism? AB - Parole officers are an integral part of parolees' reentry process and success. Few studies, however, have examined whether the quality of the relationship between parolees and their parole officer influences outcomes such as recidivism. This study assesses how recidivism is affected by the quality of the relationship that parolees have with their parole officers. Using the Serious and Violent Offender Reentry Initiative (SVORI) dataset, we use parolees' perceptions of their relationship with their parole officer to determine whether they have established a positive or negative relationship, and whether these types of relationships differentially affect recidivism. Results show that parolees who have a negative relationship with their parole officer have higher rates of recidivism, while a positive relationship lowers parolees' likelihood of recidivating. An implication of this study emphasizes parole officer training that develops positive, high-quality relationships with parolees. Further implications are discussed below. PMID- 29188733 TI - Investigational drugs in clinical trials for Hidradenitis Suppurativa. AB - INTRODUCTION: Hidradenitis suppurativa is a chronic skin disease with a significant unmet need for treatment options. Randomized controlled trials are few and only a single drug (adalimumab) has Hidradenitis as a registered indication. Areas covered: The clinicaltrials.gov and the EudraCT clinical trials register for reported trials on Hidradenitis Suppurativa was searched on the 22 06-2017. Trials for upcoming new drugs for HS are reported focusing on drugs in phase I and II trials. Expert opinion: Currently, MABp1, Secukinumab, CJM112, Apremilast and IFX-1 are being investigated in Phase I and II trials and offer theoretical and promising new treatment options. A trial with the drug MEDI8968 has been terminated with disappointing results. Metformin, Botulinum Toxin B, Provodine, Benzoyl Peroxide and intralesional triamcinolone are being tested as well. Treatment of Hidradenitis remains a challenge and quality RTCs are needed. Studies indicates a range of potential targets for therapy such as interleukin-1 and interleukin-17, but 'broad-spectrum' immunosuppressants like phosphodiesterase-4 inhibitors are being examined as well. A range of outcomes, including Physician Global Assessment, Sartorius scores and hidradenitis suppurativa clinical response are used in these trials, making future meta analysis of the data difficult. PMID- 29188734 TI - Psychiatric (Axis I) and personality (Axis II) disorders and subjective psychiatric symptoms in chronic tinnitus. AB - OBJECTIVE: Chronic tinnitus has been associated with several psychiatric disorders. Only few studies have investigated these disorders using validated diagnostic interviews. The aims were to diagnose psychiatric and personality disorders with structured interviews, to assess self-rated psychiatric symptoms and elucidate temporal relations between psychiatric disorders and tinnitus. DESIGN: Current and lifetime DSM-IV diagnoses of axis-I (psychiatric disorders) and axis-II (personality disorders) were assessed using structured clinical interviews (SCID-I and -II). Current subjective psychiatric symptoms were evaluated via self-rating instruments: the Symptom Check List-90 (SCL-90), the Beck Depression Inventory, and the Dissociative Experiences Scale (DES). STUDY SAMPLE: 83 patients (mean age 51.7, 59% men) with chronic, disturbing tinnitus and a median Tinnitus Handicap Inventory score of 32. RESULTS: The rates of lifetime and current major depression were 26.5% and 2.4%. The lifetime rate of obsessive-compulsive personality disorder (type C) was 8.4%. None of the patients had cluster B personality disorder or psychotic symptoms. The SCL-90 subscales did not differ from the general population, and median DES score was low, 2.4. CONCLUSIONS: Tinnitus patients are prone to episodes of major depression and often also have obsessive-compulsive personality features. Psychiatric disorders seem to be comorbid or predisposing conditions rather than consequences of tinnitus. Clinical trial reference: ClinicalTrials.gov (ID NCT 01929837).

AB - OBJECTIVE: The deeper research of N-octyl-N-arginine chitosan (OACS) as intravenous delivery was characterized, cell uptake study, pharmacokinetics, and biodistribution of OACS micelles (GA-OACS) were investigated. SIGNIFICANCE: Gambogic acid (GA) can inhibit the growth of various cancer cells. However, the short elimination half-life time and treatment without targeting limits its application. OACS was synthesized as delivery carrier for GA by us, but the deeper characterization of OACS, such as molecular modeling, pharmacokinetics, and biodistribution were not investigated. METHODS: Gambogic acid loaded OACS micelles (GA-OACS) were evaluated by the molecular modeling, characterized by TEM, DLS, IR, 1HNMR, XRD. Confocal laser scanning microscope and flow cytometry were analyzed for cell uptake study. Imaging analysis was used to show the distribution of OACS in vivo directly, pharmacokinetics and biodistribution were also investigated. RESULTS: The molecular modeling result showed that GA could encapsulated stably in the core of OACS micelles. TEM, IR, 1HNMR, and XRD also suggested that GA was encapsulated in amorphous form in the core of OACS micelles. AUC and elimination half-life of GA-OACS were all increased by 1.5-fold and 2.0-fold compared with GA-ARG in rat, respectively. Biodistribution study indicated that GA-OACS was distributed mainly in the liver. GA amount in the kidney and heart was greatly reduced in the GA-OACS group. From the imaging analysis, OACS distribution in the liver was the most. CONCLUSIONS: OACS was an excellent carrier for GA intravenous delivery to prolong half-life. Moreover, OACS targeted on liver.

PMID- 29188739 TI - Factors influencing the educational impact of Mini-CEX and DOPS: A qualitative synthesis. AB - INTRODUCTION: The educational impact of Mini-CEX and DOPS varies greatly and can be influenced by several factors. However, there is no comprehensive analysis and synthesis of the described influencing factors. METHODS: To fill this gap, we chose a two-step approach. First, we performed a systematic literature review and selected articles describing influencing factors on the educational impact of Mini-CEX and DOPS. Second, we performed a qualitative synthesis of these factors. RESULTS: Twelve articles were included, which revealed a model consisting of four themes and nine subthemes as influencing factors. The theme context comprises "time for Mini-CEX/DOPS" and "usability of the tools", and influences the users. The theme users comprises "supervisors' knowledge about how to use Mini CEX/DOPS", "supervisors' attitude to Mini-CEX/DOPS", "trainees' knowledge about Mini-CEX/DOPS", and "trainees' perception of Mini-CEX/DOPS". These influence the implementation of Mini-CEX and DOPS, including "observation" and "feedback". The theme implementation directly influences the theme outcome, which, in addition to the educational impact, encompasses "trainees' appraisal of feedback". CONCLUSIONS: Our model of influencing factors might help to further improve the use of Mini-CEX and DOPS and serve as basis for future research. PMID- 29188738 TI - Sialic acid-modified solid lipid nanoparticles as vascular endothelium-targeting carriers for ischemia-reperfusion-induced acute renal injury. AB - In an attempt to improve therapeutic efficacy of dexamethasone (DXM)-loaded solid lipid nanoparticles (NPs) for renal ischemia-reperfusion injury (IRI)-induced acute renal injury (AKI), sialic acid (SA) is used as a ligand to target the inflamed vascular endothelium. DXM-loaded SA-conjugated polyethylene glycol (PEG)ylated NPs (SA-NPs) are prepared via solvent diffusion method and show the good colloidal stability. SA-NPs reduce apoptotic human umbilical vein endothelial cells (HUVECs) via downregulating oxidative stress-induced Bax, upregulating Bcl-xL, and inhibiting Caspase-3 and Caspase-9 activation. Cellular uptake results suggest SA-NPs can be specifically internalized by the inflamed vascular endothelial cells (H2O2-pretreated HUVECs), and the mechanism is associated with the specific binding between SA and E-selectin receptor expressed on the inflamed vascular endothelial cells. Bio-distribution results further demonstrated the enhanced renal accumulation of DXM is achieved in AKI mice treated with SA-NPs, and its content is 2.70- and 5.88-fold higher than those treated with DXM and NPs at 6 h after intravenous administration, respectively. Pharmacodynamic studies demonstrate SA-NPs effectively ameliorate renal functions in AKI mice, as reflected by improved blood biochemical indexes, histopathological changes, oxidative stress levels and pro-inflammatory cytokines. Moreover, SA-NPs cause little negative effects on lymphocyte count and bone mineral density while DXM leads to severe osteoporosis. It is concluded that SA-NPs provide an efficient and targeted delivery of DXM for ischemia-reperfusion induced injury-induced AKI, with improved therapeutic outcomes and reduced adverse effects. PMID- 29188740 TI - The effect of tinnitus specific intracochlear stimulation on speech perception in patients with unilateral or asymmetric hearing loss accompanied with tinnitus and the effect of formal auditory training. AB - OBJECTIVES: Previous studies show that intracochlear electrical stimulation independent of environmental sounds appears to suppress tinnitus, even long-term. In order to assess the viability of this potential treatment option it is essential to study the effects of this tinnitus specific electrical stimulation on speech perception. DESIGN: A randomised, prospective crossover design. STUDY SAMPLE: Ten patients with unilateral or asymmetric hearing loss and severe tinnitus complaints. RESULTS: The audiological effects of standard clinical CI, formal auditory training and tinnitus specific electrical stimulation were investigated. Results show that standard clinical CI in unilateral or asymmetric hearing loss is shown to be beneficial for speech perception in quiet, speech perception in noise and subjective hearing ability. Formal auditory training does not appear to improve speech perception performance. However, CI-related discomfort reduces significantly more rapidly during CI rehabilitation in subjects receiving formal auditory training. Furthermore, tinnitus specific electrical stimulation has neither positive nor negative effects on speech perception. CONCLUSIONS: In combination with the findings from previous studies on tinnitus suppression using intracochlear electrical stimulation independent of environmental sounds, the results of this study contribute to the viability of cochlear implantation based on tinnitus complaints. PMID- 29188741 TI - Adherence to Oral Medications During Maintenance Therapy Among Children and Adolescents With Acute Lymphoblastic Leukemia: A Medication Refill Analysis. AB - Adherence to oral medications during maintenance therapy is essential for pediatric patients with acute lymphoblastic leukemia. Self-reported or electronic monitoring of adherence indicate suboptimal adherence, particularly among particular sociodemographic groups. This study used medication refill records to examine adherence among a national sample of pediatric patients with acute lymphoblastic leukemia. Patients in a national claims database, aged 0 to 21 years with a diagnosis of acute lymphoblastic leukemia and in the maintenance phase of treatment, were included. Medication possession ratios were used as measures of adherence. Overall adherence and adherence by sociodemographic groups were examined. Adherence rates were 85% for 6-mercaptopurine and 81% for methotrexate. Adherence was poorer among patients 12 years and older. Oral medication adherence rates were suboptimal and similar to or lower than previously documented rates using other methods of assessing adherence. Refill records offer a promising avenue for monitoring adherence. Additional work to identify groups most at-risk for poor adherence is needed. Nurses are well positioned to routinely monitor for medication adherence and to collaborate with the multidisciplinary team to address barriers to adherence. PMID- 29188742 TI - Management of pathologic node-positive disease following initial surgery for clinical T1-2 N0 esophageal cancer: patterns of care and outcomes from the national cancer data base. AB - PURPOSE: Although clinical T1-2N0 esophageal cancer (EC) is often initially surgically resected (without neoadjuvant therapy), several studies have illustrated substantial rates of discovering pathologically node-positive disease. This study evaluated national practice patterns of adjuvant therapy for this population. METHODS: The National Cancer Database (NCDB) was queried (2004 2013) for patients with cT1-2N0M0 EC that received up-front surgery (esophagectomy/local techniques) with subsequent discovery of nodal metastasis. Patients receiving any neoadjuvant therapy were excluded. Multivariable logistic regression determined factors predictive of receiving adjuvant therapy. Kaplan Meier analysis evaluated overall survival (OS), and Cox proportional hazards modeling determined variables associated with OS. Propensity score matching assessed groups in a balanced manner while reducing indication biases. RESULTS: Altogether, 715 patients met inclusion criteria; 114 (16%) underwent adjuvant chemotherapy, 183 (26%) chemoradiation, 16 (2%) radiotherapy alone, and 402 (56%) observation. Observation was more likely performed with advanced age (p = .002) and at nonacademic centers (p = .001). Median OS in the respective cohorts were 42.6, 35.1, 22.2, and 27.0 months. Both chemotherapy and chemoradiation were statistically similar (p = .462) but superior to observation (p < .05 for both). There was a survival benefit to any adjuvant treatment (median OS 38.5 vs. 27.0 months, p < .001), which persisted after propensity matching (median OS 35.1 vs. 24.3 months, p < .001). On multivariable analysis, any adjuvant treatment was independently associated with improved OS, along with treatment at an academic center (p < .05 for all). CONCLUSIONS: In the largest study to date evaluating patterns of care for pN + disease following resection of cT1-2N0 EC, a strikingly high proportion of patients were observed. Adjuvant treatment, ideally chemotherapy or chemoradiation, independently correlated with higher survival, and should be considered in able patients. Treatment at academic facilities also associated with higher survival, which has implications for patient counseling.

Careful analysis of EEG records can provide valuable insight and improved understanding of the mechanism causing epileptic disorders. The detection of epileptic form discharges in EEG is an important component in the diagnosis of epilepsy. As EEG signals are non stationary, the conventional frequency and time domain analysis does not provide better accuracy. So, in this work an attempt has been made to provide an overview of the determination of epilepsy by implementation of Hurst exponent (HE)-based discrete wavelet transform techniques for feature extraction from EEG data sets obtained during ictal and pre ictal stages of affected person and finally classifying EEG signals using SVM and KNN Classifiers. The The highest accuracy of 99% is obtained using SVM. PMID- 29188744 TI - Contraception in adolescents with intellectual disability. AB - OBJECTIVES: The aims of the study were to investigate the reasons for first gynaecological consultation in adolescents with intellectual disability (ID) and assess how contraception is prescribed with regard to the different contraceptive methods, their medical indications, adverse effects and compliance, in comparison with a group of adolescents without ID. METHODS: A retrospective case-control study was conducted among 200 adolescents with ID (group A) and a control group of 200 adolescents without ID (group B). RESULTS: The main reasons for gynaecological consultation in group A were 'need for contraception' (46.5% in group A vs 32.0% in group B, p = .003) and abnormal uterine bleeding (42.0% in group A vs 27.0% in group B, p = .002). Contraception was prescribed in 80.0% of the adolescents in both groups. Combined oral contraception was prescribed in 83.1% in group A vs. 91.3% in group B (p = .03). The transdermal patch was more prevalent in group A (6.3% vs. 0.6% in group B, p = .006). Other contraceptive methods were similar between the two groups. In group B there were 5.0% unintended pregnancies vs no cases in group A (p = .001). Sexual abuse occurred similarly in both groups (2.5% in group A vs 2.0% in group B, p = not significant). CONCLUSION: The need for contraception in adolescents with ID is a frequent reason for gynaecological consultation, despite their younger age and lower number who are sexually active. Combined oral contraception is the most prescribed method in adolescents with ID; however, the transdermal patch also plays an important role in this group. PMID- 29188745 TI - Bariatric surgery versus conservative management for morbidly obese patients in Spain: a cost-effectiveness analysis. AB - BACKGROUND: We assessed the cost-effectiveness of bariatric surgery (BS) versus conservative management (CM) for treating morbid obesity in Spain. METHODS: We developed a probabilistic Markov model to estimate health outcomes, quality adjusted life years (QALY), life years gained (LYG), and costs over lifetime and 10-year horizons. Combined common BS procedures were compared with CM. Clinical and utility inputs were obtained from the literature and resource use and costs from local sources (?2017). RESULTS: Over the 10-year horizon, BS led to a cost increment of ?9,386 and 1.6 additional QALY (?5,966/QALY). Leading to 0.6 LYG and 4.4 QALY gains and ?300/patient average cost savings over lifetime, BS could potentially significantly reduce diabetes and cardiovascular disease risk over the considered horizons. Despite short-term cost reductions, surgery delay may lead to significant clinical benefits loss. CONCLUSIONS: Compared to CM, BS is a more effective and less costly alternative for treating morbid obesity in Spain. PMID- 29188747 TI - Development and characterization of clay facial mask containing turmeric extract solid dispersion. AB - OBJECTIVE: To develop clay facial mask containing turmeric extract solid dispersion (TESD) for enhancing curcumin water solubility and permeability and to determine suitable clay based facial mask. METHODS: The TESD were prepared by solvent and melting solvent method with various TE to polyvinylpyrrolidone (PVP) K30 mass ratios. The physicochemical properties, water solubility, and permeability were examined. The effects of clay types on physical stability of TESD, water adsorption, and curcumin adsorption capacity were evaluated. RESULTS: The TESD prepared by solvent method with a TE to PVP K30 mass ratio of 1:2 showed physically stable, dry powders, when mixed with clay. When TESD was dissolved in water, the obtained TESD micelles showed spherical shape with mean size of ~100 nm resulting in a substantial enhancement of curcumin water solubility, ~5 mg/ml. Bentonite (Bent) and mica (M) showed the highest water adsorption capacity. The TESD's color was altered when mixed with Bent, titanium dioxide (TiO2) and zinc oxide (ZnO) indicating curcumin instability. Talcum (Talc) showed the greatest curcumin adsorption followed by M and kaolin (K), respectively. Consequently, in vitro permeation studies of the TESD mixed with Talc showed lowest curcumin permeation, while TESD mixed with M or K showed similar permeation profile as free TESD solutions. The developed TESD-based clay facial mask showed lower curcumin permeation as compared to those formulations with Tween 80. CONCLUSION: The water solubility and permeability of curcumin in clay based facial mask could be improved using solid dispersion technique and suitable clay base composed of K, M, and Talc. PMID- 29188748 TI - Regional dialect perception across the lifespan: Identification and discrimination. AB - Although adult listeners can often identify a talker's region of origin based on his or her speech, young children typically fail in dialect perception tasks, and little is known about the development of regional dialect representations from childhood into adulthood. This study explored listeners' understanding of the indexical importance of American English regional dialects across the lifespan. Listeners between 4 and 79 years old in the Midwestern United States heard talkers from the Midland, Northern, Southern, and New England regions in two regional dialect perception tasks: identification and discrimination. The results showed that listeners as young as 4-5 years old understand the identity-marking significance of some regional dialects, although adult-like performance was not achieved until adolescence. Further, the findings suggest that regional dialect perception is simultaneously impacted by the specific dialects involved and the cognitive difficulty of the task. PMID- 29188746 TI - Can neuroimaging help aphasia researchers? Addressing generalizability, variability, and interpretability. AB - Neuroimaging studies of individuals with brain damage seek to link brain structure and activity to cognitive impairments, spontaneous recovery, or treatment outcomes. To date, such studies have relied on the critical assumption that a given anatomical landmark corresponds to the same functional unit(s) across individuals. However, this assumption is fallacious even across neurologically healthy individuals. Here, we discuss the severe implications of this issue, and argue for an approach that circumvents it, whereby: (i) functional brain regions are defined separately for each subject using fMRI, allowing for inter-individual variability in their precise location; (ii) the response profile of these subject-specific regions are characterized using various other tasks; and (iii) the results are averaged across individuals, guaranteeing generalizabliity. This method harnesses the complementary strengths of single-case studies and group studies, and it eliminates the need for post hoc "reverse inference" from anatomical landmarks back to cognitive operations, thus improving data interpretability. PMID- 29188749 TI - Bleeding during veno-venous ECMO cannot reliably be predicted by rotational thrombelastometry (ROTEMTM). AB - INTRODUCTION: Veno-venous extracorporeal membrane oxygenation (vvECMO) used for respiratory support is associated with clinical bleeding in at least one third of patients. Mechanisms promoting bleeding, like acquired von Willebrand syndrome, cannot be identified by routine coagulation tests. This study was performed to evaluate rotational Thrombelastography (ROTEMTM) for specific results predicting bleeding events during vvECMO. METHODS: Five hundred and thirty-four ROTEMTM analyses of 57 patients over 574 days have been evaluated. Patients were graded into three groups according to the severity of bleeding, following the Freiburg ECMO bleeding assessment. ROTEMTM results and basic as well as comprehensive laboratory coagulation tests have been compared among the three groups and overall between defined time points. RESULTS: Fourteen patients (25 %) presented without bleeding, 22 patients (39 %) showed mild bleeding and 21 patients (36 %) became evident with relevant clinical bleeding. No bleeding shock and no fatal bleeding event occurred. No case of hyperfibrinolysis was observed. Neither a statistical difference for ECMO blood flow nor duration of therapy among the groups could be shown. The only significant difference was clotting time (CT) in the InTEM analysis, with a median (IQR) of 175 (37.5) seconds in Group 1, 190 (54.5) seconds in Group 2 and 204 (90) seconds in Group 3. When comparing overall ROTEMTM analyses between defined time points, continuous worsening of CT can be found in ExTEM, FibTEM and ApTEM. Reduced A10, A20 and congruently maximum clot firmness, especially, developed in ExTEM and ApTEM and with a minor characteristic in InTEM, but not in FibTEM. ROTEMTM and coagulation-parameter results before 19 clinical relevant bleeding episodes compared to all other results only showed differences in FibTEM. CONCLUSION: ROTEMTM as a functional viscoelastic analysis does not provide additional information to basic and comprehensive laboratory tests during vvECMO. Bleeding events cannot be predicted by the means of specific ROTEMTM results.

AB - PURPOSE: To explore the perceptions of people with severe knee osteoarthritis and increased cardiovascular risk about participating in a walking program. METHODS: Qualitative study using semistructured interviews for people with severe knee osteoarthritis and increased cardiovascular risk who participated in a 12-week walking program. Interviews were audiotaped, transcribed verbatim, member checked, coded and themes developed using thematic analysis. Findings were triangulated with quantitative data including pain, function and cardiovascular risk factors from previously reported data. RESULTS: Twenty-one participants were interviewed after the completion of the walking program. The main theme identified was the preoccupation with the knee including pain, damage and the view that surgery was required. Three subthemes to emerge were (i) the perception of functional, cardiovascular and psychosocial benefits with the walking program; (ii) that supervision, monitoring and commitment were important enablers; and (iii) external factors such as ill-health, weather and the environment were key barriers. The perceived functional and cardiovascular benefits converged with results from quantitative data. CONCLUSIONS: Even when patients with severe osteoarthritis of the knee report other benefits from participating in a walking program, the core theme to emerge was their preoccupation with knee pain, knee damage and the view that they needed a knee replacement. Implications for Rehabilitation Patients with severe osteoarthritis of the knee and moderate cardiovascular risk reported functional, cardiovascular and psychosocial benefits from participating in a walking program. Despite patients reporting functional, cardiovascular and psychosocial benefits, the core theme to emerge was their preoccupation with knee pain, knee damage and the view that they needed a knee replacement. The core theme highlights the challenges in promoting physical activity for patients with severe knee osteoarthritis. PMID- 29188751 TI - Go with the flow: GEF-H1 mediated shear stress mechanotransduction in neutrophils. AB - Neutrophils in circulation experience significant shear forces due to blood flow when they tether to the vascular endothelium. Biochemical and biophysical responses of neutrophils to the physical force of flowing blood modulate their behavior and promote tissue recruitment under pro-inflammatory conditions. Neutrophil mechanotransduction responses occur through mechanisms that are not yet fully understood. In our recent work, we showed that GEF-H1, a RhoA specific guanine nucleotide exchange factor (GEF), is required to maintain neutrophil motility and migration in response to shear stress. GEF-H1 re-localizes to flottilin-rich uropods in neutrophils in response to fluid shear stress and promotes spreading and crawling on activated endothelial cells. GEF-H1 drives cellular contractility through myosin light chain (MLC) phosphorylation downstream of the Rho-ROCK signaling axis. We propose that GEF-H1-dependent cell spreading and crawling in shear stress-dependent neutrophil recruitment from the vasculature are due to the specific localization of Rho-induced contractility in the uropod. PMID- 29188752 TI - Patterns of Adverse Childhood Experiences in Juveniles Who Sexually Offended. AB - Juveniles who sexually offended (JSOs) are differentially burdened with adverse childhood experiences (ACEs). The present study used Latent Class Analysis (LCA) to derive subtypes of JSOs according to their patterns of 10 different ACEs. An extensive file analysis of 322 male JSOs ( M = 14.14, SD = 1.94) revealed five subtypes with (a) multiple (9.0%), (b) mainly family related (17.1%), (c) mainly peer related (21.7%), (d) mainly neglectful (18.6%), and (e) little/no (33.5%) ACEs. Differences among ACE subtypes with regard to several offense and victim characteristics (e.g., the use of penetration or violence, the choice of a child, a male, a stranger, or multiple victims) were examined. Whereas no differences were found for the use of physical violence or the choice of male, stranger, or multiple victims, binary logistic regressions revealed associations of the multiple-ACE subtype with the choice of a child victim, the family-ACE subtype with the use of penetration as well as further nonsexual delinquency, the peer ACE subtype with the use of penetration and the choice of a child victim, and the neglect-subtype with the choice of a child victim. Additional analyses including single ACE categories instead of LCA-derived subtypes supported these results. Findings highlight the need for a comprehensive consideration of ACEs in research and clinical work to understand developmental pathways to juvenile sexual offending.

PMID- 29188754 TI - "It's Sort of Reaffirmed to Me That I'm Not a Monster, I'm Not a Terrible Person": Sex Offenders' Movements Toward Desistance via Peer-Support Roles in Prison. AB - Individuals incarcerated in prisons across the United Kingdom and abroad are able to volunteer for a variety of peer-support roles, which are characterized by prisoner-to-prisoner helping. Some research has found that such roles can represent turning points in the lives of those who have offended and encourage movements toward desistance. This proposed redemptive influence is argued to result from the prosocial behaviors that such roles appear to elicit in their holders. The present study aims to explore the mechanics of this claimed influence. While a limited amount of research has attempted this on a general offending population, no research has done so with a sample of sexual offenders. Given the intensive treatment programs involved in such contexts, and the requirements for sexual offenders to demonstrate reduced risk, the authors believe those serving time for sexual offenses represent an important sample on which to explore the potentially redemptive properties of peer-support roles. To this end, 13 peer supporters participated in semistructured interviews. Transcripts were analyzed using a phenomenologically oriented thematic analysis. Results suggest that sexual offenders who adopt peer-support roles are able to live up to desired selves by "doing good" in prison, "giving back," and consequently resisting negative labels. These benefits have been theoretically linked with better reintegration outcomes for sexual offenders, who are publicly denigrated in the extreme and find it especially difficult to (re)integrate. Suggestions regarding the future utility of such schemes are offered. PMID- 29188755 TI - Approach and Avoidance Tendencies Toward Picture Stimuli of (Pre-)Pubescent Children and Adults: An Investigation in Pedophilic and Nonpedophilic Samples. AB - The presence of pedophilic sexual interests is considered of high importance for predicting recidivism among individuals who have committed sexual offenses. However, objective and valid assessment methods that are robust against confounding issues such as cognitive capacity and manipulation are sparse. We applied the Approach-Avoidance Task (AAT) for detecting sexual interests in 38 pedophilic men (18 primarily attracted to boys) and 27 male nonpedophilic (11 gay) participants. The AAT relies on automatic approach and avoidance tendencies, independent of cognitive abilities such as memory capacity and intelligence. Approach-avoidance tendencies toward stimuli depicting seminude prepubescent boys and girls as well as men and women are reported. The results were consistent with previous research on the utility of the AAT: Except for pedophiles attracted to girls, the mean AAT scores (approach minus avoidance reaction time for each stimulus category) were positive only for stimuli of the preferred category. A multivariate binary logistic regression approach revealed 80% overall accuracy in differentiating pedophilic from nonpedophilic participants. PMID- 29188756 TI - Psychosocial Correlates of Attitudes Toward Male Sexual Violence in a Sample of Financial Crime, Property Crime, General Violent, and Homicide Offenders. AB - Although those currently serving prison sentences for sexual violence can be identified and receive treatment, the number of prisoners with a history of sexual violence against female partners is unknown. Methods to identify prisoners with a proclivity for such violence and accurately assess the risk they pose before and after incarceration are therefore required. Here, we aimed to assess the level of sexually violent attitudes within dating relationships and to examine their associations with experiences of child abuse and neglect (CAN), psychopathic personality traits, prisonization, number of incarcerations, age, years of schooling, relationship status, and parenting among different types of offenders (financial crime, property crime, general violent, and homicide offenders). Data were collected among a large systematically selected sample of adult male inmates ( N = 1,123). We demonstrated that sexual violence-supportive attitudes appear to be a function of child sexual abuse and psychopathic personality traits, and may be developed through early socialization experiences as well as incarceration. Practical implications of current findings are discussed. PMID- 29188757 TI - Folate receptor-targeted multimodal fluorescence mesosilica nanoparticles for imaging, delivery palladium complex and in vitro G-quadruplex DNA interaction. AB - New folic acid-conjugated mesoporous silica nanoparticles were synthesized. The effect of calcination at 400 degrees C on the fluorescence characteristics of mesoporous silica nanoparticles were studied in this work. The formed carbon dots (CDs) from calcination were used as the source of fluorescence. 3 Aminopropyltriethoxysilane was then used to amine-functionalized the fluorescent surface of mesoporous silica nanoparticles. The amine fluorescence mesoporous silica nanoparticles (amine-FMSNs) were coupled with folic acid (FA) as the target ligand (FA-amine-FMSNs). A palladium complex was also synthesized and encapsulated in the FA-amine-FMSNs yielded fluorescent property with therapeutic effect. The in vitro release of an entrapped palladium complex from FA-amine FMSNs was studied under physiological conditions. According to the cell viability assay on HeLa (positive FR) and Hep-G2 (negative FR) cells, the targeted delivery system inhibited the growth of positive FR with higher selectivity compared with negative FR cells. Also, the emission CDs were used for fluorescence microscopic imaging. To confirm anti-cancer activity of the palladium complex, the interaction between palladium complex and G-quadruplex DNA were investigated with multi-spectroscopic methods and molecular modeling. The molecular docking studies showed a partial intercalation mode with a 4.27 * 105 M-1 binding constant. PMID- 29188758 TI - Utility of intraoperative computed tomography for cochlear implantation in patients with difficult anatomy. AB - OBJECTIVE AND IMPORTANCE: To describe cases that illustrate the utility of intraoperative computed tomography (CT) in cochlear implantation of patients with difficult temporal bone anatomy. CLINICAL PRESENTATION: A 2-year-old male with congenital X-linked stapes gusher syndrome and a 2-year-old female with enlarged vestibular aqueduct underwent successful cochlear implantation with the help of intraoperative CT. In the latter case, the initial intraoperative C-arm fluoroscopy suggested malposition of the electrode, however, was not able to provide details for adjustments. In both cases, intraoperative CT changed the insertion technique of the operating surgeon and allowed for improved electrode positioning. A 47-year-old female with polyostotic fibrous dysplasia and a 55 year-old male with post-meningitis near-total cochlear obliteration underwent successful cochlear implantation with confirmation of electrode position with intraoperative CT. In the former case, the image-guided navigation system was also implemented. Finally, a 72-year-old female underwent cochlear implantation during which intraoperative C-arm fluoroscopy suggested intra-cochlear insertion. However, postoperative CT showed the electrode extending into the internal auditory canal (IAC), illustrating the limitations of C-arm fluoroscopy. INTERVENTION: Intraoperative CT imaging and image-guided navigation system. CONCLUSION: When faced with challenging temporal bone anatomy, intraoperative CT can provide critical details of the patient's microanatomy that allows for improved localization of the electrode and adjustments in operative techniques for successful cochlear implantation. PMID- 29188759 TI - Identifying free-text features to improve automated classification of structured histopathology reports for feline small intestinal disease. AB - The histologic evaluation of gastrointestinal (GI) biopsies is the standard for diagnosis of a variety of GI diseases (e.g., inflammatory bowel disease [IBD] and alimentary lymphoma [ALA]). The World Small Animal Veterinary Association (WSAVA) Gastrointestinal International Standardization Group proposed a reporting standard for GI biopsies consisting of a defined set of microscopic features. We compared the machine classification accuracy of free-text microscopic findings with those represented in the WSAVA format with a diagnosis of IBD and ALA. Unstructured free-text duodenal biopsy pathology reports from cats ( n = 60) with a diagnosis of IBD ( n = 20), ALA ( n = 20), or normal ( n = 20) were identified. Biopsy samples from these cases were then scored following the WSAVA guidelines to create a set of structured reports. Three supervised machine-learning algorithms were trained using the structured and then the unstructured reports. Diagnosis classification accuracy for the 3 algorithms was compared using the structured and unstructured reports. Using naive Bayes and neural networks, unstructured information-based models achieved higher diagnostic accuracy (0.90 and 0.88, respectively) compared to the structured information-based models (0.74 and 0.72, respectively). Results suggest that discriminating diagnostic information was lost using current WSAVA microscopic guideline features. Addition of free-text features (number of plasma cells) increased WSAVA auto classification performance. The methodologies reported in our study represent a way of identifying candidate microscopic features for use in structured histopathology reports.

AB - OBJECTIVE: To evaluate the incidence of surgical complications of cochlear implantation and their management at K.E.M. hospital Pune. METHODS: It was a retrospective and prospective observational study conducted from February 2006 to December 2015 in the paediatric age group of 12 months to 5 years (213 cases). The complications were divided into major and minor groups based on the classification proposed by Cohen and Hoffman. RESULTS: The mean age of implantation was 3.03 years (ranged from 1 to 4.11 years). Sixteen patients had complications. The overall incidence of complications was 7.51% which comprised of major (2.34%) and minor (5.16%) complications. The commonest major complications were flap-related issues and the commonest minor complication was facial paresis. DISCUSSION: The results of our study were compared with similar studies conducted in the past. All surgical complications were treated conservatively or surgically with success. CONCLUSIONS: Cochlear implantation is the safe procedure in children between the age group of 12 months and less than 5 years.

AB - BACKGROUND: This cross-sectional study determines the association between 10-year cardiovascular disease (CVD) risk, estimated using four CVD risk assessment tools, and metabolic syndrome (MetS) in northern Iranian general population. METHODS: We used the data of 2371 participants aged 40-74 without any history of diabetes mellitus from a cohort study conducted among 6140 subjects aged 10-90 years in northern Iran. Three definitions of MetS were used. The four CVD risk assessment tools used to estimate the 10-year CVD risk included pooled cohort equations of ACC/AHA, Systematic Coronary Risk Evaluation (SCORE) equations (for low-risk and high-risk European countries), and Framingham general cardiovascular risk profile for use in primary care. Logistic regression was used to determine the association between various definitions of MetS and 10-year CVD risk of >=5%, >= 7.5%, and >=10%, based on the related risk assessment tools. RESULTS: In men, univariate logistic regression analysis showed the strongest association between 10-year risk of >=0.1 estimated by Framingham risk profile and the three definitions of MetS. In women, the 10-year risks by Framingham risk profile and SCORE equations for high-risk European countries had stronger associations with various definitions of MetS than others. No significant associations were detected between estimated risks of four risk assessment tools and various definitions of MetS in multivariate logistic regression analyses. CONCLUSION: No independent associations were observed between estimations of 10-year CVD risk using four risk assessment tools and various definitions of MetS. PMID- 29188762 TI - Developmental Trajectories of Child Sexual Behaviors on the Path of Sexual Behavioral Problems: Evidence From a Prospective Longitudinal Study. AB - There is little information about the onset and the developmental course of child sexual behavior problems (SBPs), including sexually intrusive behaviors (SIBs). Using data from the Vancouver Longitudinal Study on the Psychosocial Development of Children, the current study examined the presence of distinct patterns of sexual development among children. A normative sample of preschoolers ( N = 354) with a small clinical subsample were followed from age 3 to 8 with repetitive measurements of sexual behaviors using a revised version of Child Sexual Behavior Inventory. Semiparametric group-based modeling identified four distinct sexual development trajectories: the very low (10.5%), the low declining (27.8%), the moderate stable (48.3%), and the high-rate increasing (13.4%). In contrast to the other developmental trajectories found, the high-rate-increasing pattern showed that sexual behaviors became increasingly extensive after school entry. Children characterized by this developmental pattern, especially boys, were more likely to be involved in SIBs after elementary school entry than those in the other groups. Findings highlight the presence of multiple developmental trajectories of sexual development with significantly different behavioral patterns after school entry.

AB - A 35-year-old male with acute liver failure due to acute hepatitis B virus infection was admitted to the intensive care unit with significant hepatocellular injury, cholestasis, abnormal standard coagulation tests, normal rotational thromboelastometry indices, and without signs of bleeding. He underwent emergency liver transplantation without requiring blood product transfusions or procoagulant treatments. The postoperative course was complicated by deep vein thrombosis and impending hepatic artery thrombosis treated with unfractionated heparin, aspirin, and intravenous prostacyclin. The patient survived and made a full neurological recovery. This case revealed the presence of a prothrombotic state due to a rebalanced coagulation system in a patient with liver dysfunction that was not identifiable by standard coagulation tests. This case emphasizes that identifying and treating coagulopathy is very difficult in liver failure patients and requires specific diagnostic and therapeutic strategies. PMID- 29188764 TI - Assessing the performance of methodological search filters to improve the efficiency of evidence information retrieval: five literature reviews and a qualitative study. AB - BACKGROUND: Effective study identification is essential for conducting health research, developing clinical guidance and health policy and supporting health care decision-making. Methodological search filters (combinations of search terms to capture a specific study design) can assist in searching to achieve this. OBJECTIVES: This project investigated the methods used to assess the performance of methodological search filters, the information that searchers require when choosing search filters and how that information could be better provided. METHODS: Five literature reviews were undertaken in 2010/11: search filter development and testing; comparison of search filters; decision-making in choosing search filters; diagnostic test accuracy (DTA) study methods; and decision-making in choosing diagnostic tests. We conducted interviews and a questionnaire with experienced searchers to learn what information assists in the choice of search filters and how filters are used. These investigations informed the development of various approaches to gathering and reporting search filter performance data. We acknowledge that there has been a regrettable delay between carrying out the project, including the searches, and the publication of this report, because of serious illness of the principal investigator. RESULTS: The development of filters most frequently involved using a reference standard derived from hand-searching journals. Most filters were validated internally only. Reporting of methods was generally poor. Sensitivity, precision and specificity were the most commonly reported performance measures and were presented in tables. Aspects of DTA study methods are applicable to search filters, particularly in the development of the reference standard. There is limited evidence on how clinicians choose between diagnostic tests. No published literature was found on how searchers select filters. Interviewing and questioning searchers via a questionnaire found that filters were not appropriate for all tasks but were predominantly used to reduce large numbers of retrieved records and to introduce focus. The Inter Technology Appraisal Support Collaboration (InterTASC) Information Specialists' Sub-Group (ISSG) Search Filters Resource was most frequently mentioned by both groups as the resource consulted to select a filter. Randomised controlled trial (RCT) and systematic review filters, in particular the Cochrane RCT and the McMaster Hedges filters, were most frequently mentioned. The majority indicated that they used different filters depending on the requirement for sensitivity or precision. Over half of the respondents used the filters available in databases. Interviewees used various approaches when using and adapting search filters. Respondents suggested that the main factors that would make choosing a filter easier were the availability of critical appraisals and more detailed performance information. Provenance and having the filter available in a central storage location were also important. LIMITATIONS: The questionnaire could have been shorter and could have included more multiple choice questions, and the reviews of filter performance focused on only four study designs. CONCLUSIONS: Search filter studies should use a representative reference standard and explicitly report methods and results. Performance measures should be presented systematically and clearly. Searchers find filters useful in certain circumstances but expressed a need for more user-friendly performance information to aid filter choice. We suggest approaches to use, adapt and report search filter performance. Future work could include research around search filters and performance measures for study designs not addressed here, exploration of alternative methods of displaying performance results and numerical synthesis of performance comparison results.

AB - The aim was to prepare cross linked polymer of 5-fluorouracil loaded microspheres containing guar gum and sodium borate for colon-targeted drug delivery systems. Micro spheres were prepared using emulsification cross linking method. The influence of drug polymer ratio, cross linker agent concentrations and cross linking timing on in vitro drug release and characteristics in terms of drug loading, entrapment efficiency and yielding percentage were investigated. The optimum drug loading, entrapment efficiency and percent yield were obtained from formulations with the lowest content of cross linker agent over 2 h of cross linking timing but with the highest drug to polymer ratio 1:11. The optimum in vitro drug release was obvious upon decreasing drug to polymer ratio up to 1:09, resulting in 81.5% drug release over 24 h. In conclusion, micro spheres composed of gaur gum and sodium borate can delay and control the release of 5-fluorouracil over 24 h. Thus, further in vivo studies are suggested for final assessment. PMID- 29188766 TI - Larvicidal, pupicidal and adulticidal activities of non-polar solvent extract of Cymbopogon nardus (Linn.) whole plant against a mosquito, Culex quinquefasciatus (Say.). AB - The present research is aimed to investigate the susceptibility of Cx. quinquefasciatus larvae (2nd and 4th instars), pupae and adults during exposure to various concentrations of C. nardus n-hexane extract. Increase in mortality of larvae and pupae was observed with increase in concentration of the extract solution (R2>0.90). LC50 values of extract for 2nd and 4th instar larvae were 451.8 and 599.6 ppm, respectively. The LC90 values of extract for 2nd and 4th instar larvae were 2519.6 and 3017.7 ppm, respectively. The LC50 and LC90 values of extract during pupicidal activity were 1307.7 and 2257.9 ppm, respectively. During CDC bottle bioassay, mosquito adult knockdown was observed after exposure to various concentrations (0.15% to 1.25%) of C. nardus n-hexane extract. The KDT50 values at highest (1.25%) and lowest (0.15%) concentrations were 100.9 and 184.2 minutes, respectively. After 24 hours exposure period, the highest extract concentration (1.25%) caused 62.5+/-6.5% mortality. During filter paper impregnation bioassay, the KDT50 value at highest concentration (0.13 mg/cm2) was 94.4 minutes and at lowest concentration (0.017 mg/cm2) was 178.9 minutes. KDT90 values at these concentrations were 176.7 and 290.1 minutes, respectively. After 24 hours of recovery period, the filter papers impregnated with highest extract concentration (0.13mg/cm2) caused 60+/-8.2% mortality. PMID- 29188767 TI - Development and validation of stability indicating assay method for cinitapride in bulk & tablets. AB - A simple stability indicating UV-spectrophotometric method has been developed and validated for the determination of cinitapride hydrogen tartrate (CHT) in bulk and solid pharmaceutical dosage form. Drug absorption was measured in different analytical mediums however; maximum absorption was seen in 0.1 N HCl at wavelength (lambdamax) of 266 nm. The calibration curve was found to be linear over the concentration range from 6 to14MUg/mL with the correlation coefficient value (r) of 0.999. The LOD and LOQ were estimated to be 0.1019MUg/mL and 0.309MUg/mL respectively. The accuracy was evaluated by determining the percent drug recovery, performed at three different levels of 50%, 100% and 150%. The% recovery was found to be in the range of 99.96-100.64%. The precision of the method was determined by inter-day and intra-day variations. The % RSD value <0.5 indicates the underlying method is precise and accurate as well. The developed method was applied to characterize in vitro assay content of few brands of cinitapride (1 mg) available in local market. No interference of the formulation excipients with the drug absorption was observed during assay. Drug substance and drug product were exposed to various stressed conditions (acid, base, oxidative, thermal and photolysis). Forced degradation testing of drug product showed that the oxidation (20%) was found to be the major degradation pathway of the cinitapride. However; drug estimation was not influenced in presence of degradation moieties formed during acid, base, oxidation, thermal and photolytic breakdown. Overall, the investigated technique is robust and specific that would be successfully used to quantify the cinitapride hydrogen tartarate in pharmaceutical dosage and bulk form in future.

AB - Benzylpenicillin acts through binding with beta-lactamase enzyme and inhibiting the bacterial cell wall biosynthesis. Therefore, the radiolabeling of benzylpenicillin with lutetium-177 is expected to serve as a theranostic agent for deep-seated bacterial infections. The radiolabeling of benzylpenicillin resulted ~93% radiochemical yield at optimized reaction conditions. Radiochemical purity analysis was tested with the help of Whatman No. 2 paper and instant thin layer chromatography. Biodistribution study with healthy New Zeeland white rabbit revealed moderate accumulation in different organs. Kidneys are the major organs, showed not more than 4.57+/-0.89% injected dose per gram organ (ID/gm organ) at 1 h time point and 3.48+/-1.11% ID/gm organ at 6 h time point. The accumulation of tracer agent in liver was found in the range of 7.42+/-2.42% to 9.09+/-2.76 ID/gm organ. The glomerular filtration rate studies revealed rapid clearance - omitting the chance of nephrotoxicity. The radiolabeling yield, biodistribution and glomerular filtration rate results revealed 177Lu-benzylpencillin could be a potential candidate to diagnose the deep-seated bacterial infection.

AB - A swift, precise and simple HPLC bioanalytical technique with UV detection was established and validated for quantitative estimation of valsartan in human plasma. The analyte was separated from plasma by protein precipitation with acetonitrile and chromatographically separated on Zorbax SB-C18 (5MUm, 4.6mm * 15cm) column. The solvent mixture system consisting of acetonitrile, water and glacial acetic acid (40:59:1 v/v), was pumped using isocratic mode at 1mL/min flow rate. Samples' detection of drug was made spectrophotometrically at a wavelength of 264nm. The analyte response was instituted to be linear from 0.06 to 8MUg/mL with a regression value of 0.999. The accuracy of the proposed method was ranged between 97.2-100.3% with 5% RSD. The analytical recovery (>95%) was consistently observed and satisfactory sample stability was also found at different environmental conditions. In conclusion the reported bio-analytical method is easy and robust that was successfully utilized in estimation of valsartan in a pharmacokinetic study. PMID- 29188770 TI - The hepatoprotective effects of aquatic extract of Levisticum officinale against paraquat hepatocyte toxicity. AB - Paraquat is extensively used as a strong nitrogen-based herbicide for controlling weeds in agriculture. This herbicide is extremely toxic to humans and induces multiorgan failure due to accumulation in the cells. So far, many instances of fatal poisoning have been reported. Paraquat is metabolized primarily in the liver. Accordingly, the effects of aquatic Levisticum officinale extract on biochemical factors and oxidative status were evaluated in hepatocytes exposed to paraquat in this study. The results showed that paraquat-induced hepatocyte destruction is mediated by reactive oxygen species (ROS) production. The aquatic extracts of Levisticum officinale (100, 200, and 300MUg/mL) could prevent lipid peroxidation and reduction in the potential of mitochondrial membranes (P<0.05). The antioxidants, ROS scavengers (mannitol, dimethyl sulfoxide, and alpha tocopherol), and mitochondrial permeability transition pore-sealing agent (carnitine) inhibited the effects of paraquat. The pore-sealing compound inhibited hepatotoxicity, indicating that paraquat induces cell death via mitochondrial pathways. Hepatic cell death due to paraquat could be prevented by hepatocyte pretreatment with aquatic Levisticum officinale extracts, antioxidants, and ROS scavengers; therefore, oxidative stress might directly reduce the mitochondrial membrane potential. In conclusion, paraquat hepatotoxicity may be associated with oxidative stress and maintained by the disruption of mitochondrial membrane potential. Levisticum officinale aquatic extract, presumably due to its strong antioxidant properties, could protect against the destructive effects of paraquat on rat hepatocytes.

AB - This study was designed to investigate the role of enriched environment in preventing and/or reducing the neurobehavioral deficits produced after nicotine administration in albino Wistar rats. Equal numbers of rat in two groups were either placed in social environment (control group) or social along with physically enriched environment for four weeks before the administration of nicotine. Exposure to different environmental conditions was followed by the intraperitoneal injection of nicotine at the dose of 0.6 mg/kg for seven consecutive days during which addictive behavior was monitored using conditioned placed preference paradigm. Behavioral responses to locomotor activity, anxiety and retention of short term memory were investigated in control and nicotine injected groups exposed to different environments. Results of this study showed that the rats pre-exposed to physical along with social enrichment exhibited a decrease in drug seeking behavior, hyper locomotion, anxiogenic effects along with improvement of working memory as compared to control and nicotine injected groups that were kept in social environment alone. This behavioral study suggests that the exposure to physical enrichment along with socialization in young age can later reduce the chances of compulsive dependence on nicotine and related neurobehavioral deficits.

AB - Hepatitis C is the most common health problem worldwide and is major cause of death due to proliferation of hepatocellular carcinoma. The medicines available for HCV treatment overcome up-to 95% complications of HCV. However, liver cancer needs some additional care. Normally Sorafenib tosylate 200 mg is recommended for liver cancer. There is no such trial in which this drug could effectively be used in combination of direct acting antivirals for HCV. The study was conducted for HCV patients (n=30) with liver cancer having decompensated stage. Combination of Sorafenib tosylate, Ribavirn and Sofosbuvir were used for the pharmacokinetics of these medicines. Child pugh score less then 7 (CP A) in adults during treatment phase (received 12 weeks of Sorafenib tosylate 200 mg, Ribavirn and Sofosbuvir 400 mg once daily) have no side effect while child pugh score 7-9 (CP B) have evidence of hypertension. The main efficiency end point sustained virology response with overcoming liver cancer as well in 12 weeks after end treatment (SVR-LLC 12). Mean pharmacokinetic exposure to Sorafenib tosylate 200 mg, Ribavirn and Sofosbuvir at week 8th was 2.1, 1.5,1.2 times greater in CP B than in CP A. Adverse effects (AEs) were observed in 12 out of 30 patients but not severe as lethal for life. Treatment with Sorafenib tosylate, Ribavirn and Sofosbuvir for twelve weeks was harmless and well accepted, 100 % patients achieve (SVR LLC 12) with 10-fold cure rate more than previous ones. The combination therapy of Sorafenib tosylate, Ribavirn and Sofosbuvir was found helpful for the management of decompensated liver cancer. PMID- 29188774 TI - Biologically active compounds from the red sea sponge Suberea sp. AB - Investigation of the cytotoxic fraction of the extracts of the Red Sea sponge Suberea sp. resulted in the identification of two new compounds, 1-(hydroxy(1H pyrrol-2-yl)methyl)guanidine and 4-(2-amino-3-methylbut-3-en-1-yl)phenol (1 and 2) together with the previously reported 2-(3,5-dibromo-4-hydroxyphenyl)acetamide (3), subereaphenol C (4), dibromoverongiaquinol (5) and bromochloroverongiaquinol (6). The compounds were assigned by assignment of their one- and two-dimensional NMR and MS spectral data. The cytotoxic activities of the compounds against two cancer cell lines were evaluated. In addition, the antimicrobial activities of the compounds was discussed. PMID- 29188775 TI - Isolation and characterization of antibiotic producing bacterial strains from red soil of Himalayan region of Pakistan. AB - The emergence of multi drug resistant microbial pathogens has become a global health challenge and set a dire requirement of searching new effective antimicrobials. Soil is an ultimate reservoir of biologically active micro flora, which harbors trillions of microbial strains producing compounds of commercial interest. Hence aim of the present study was an attempt to isolate and identify the antibiotic producing microbial strains from the red soil of Himalayan an unexplored region of Pakistan. In this study from 10 different soil samples only one bacterial strain was isolated capable of antimicrobial activity. Strain was identified by biochemical characteristics and final identification was done by API 20 NE kit which showed 99% homology with P. aeruginosa. Hence the strain was identified as P. aeruginosa S2. Antibacterial and antifungal activity of the P. aeruginosa S2 showed that Staphylococcus aureus was extremely sensitive to it with a zone of inhibition of 42mm. Staphylococcus epidermidis, Enterobacter aerogenes, Aspergillus fumigatus and Candida albicans were also inhibited by the isolated strain. Effect of Glycerol, Copper sulphate (CuSo4), Sodium sulphate (Na2SO4) and Glycerol on antibiotic production was also evaluated by supplementing growth media with these chemicals. Pseudomonas aeruginosa was grown in bulk quantity using solid state fermentation and crude extract was prepared using organic solvents and subjected to silica gel column chromatography for purification of active compound. Purified compound showed antibacterial against human pathogens. The unexplored Kashmir Himalayas are of great significance because of its richness in biodiversity and need to be explored for isolation and characterization of native microbes for biologically active secondary metabolites. This untouched region may be considered as hub of new antimicrobials and may have applications in natural product-based drug discovery. PMID- 29188776 TI - Metal complexes of isonicotinylhydrazide and their antitubercular activity. AB - The development and spreading of Multi Drug Resistant TB strains is hampering endeavours for the control and administration of tuberculosis (TB). The expansion episodes of multi-medication safe strains of Mycobacterium tuberculosis against first and second line antituberculosis drugs on one side and the unfavourable effects of these drugs on the other side has led the enthusiasm of researcher towards the synthesis of metal complexes of various medication. This approach is born with the expectation of finding new antituberculous operators without or least reactions as well as being active against the resistant strains of Mycobacterium tuberculosis. This study concentrates on the screening of five metal complexes of isoniazid (INH) against five Mycobacterium tuberculosis strains. These strains have been confirmed by WHO being active and even proliferating safely even in the presence of pyrazinamide, isoniazid (INH), ethambutol and rifampicin. In this work INH was taken as reference medication. All synthesized complexes and INH were subjected for a month and a half in BACTEC MGIT 960 technique. INH and its Fe (II) complex restrained the development of all bacterial strains for merely two weeks, while the Fe(III), Cu(II), Co (II) and Mn (II) complexes repressed the development five strains for three weeks. Conclusively, the strains utilized in this study were discovered to be more susceptible to the later four complexes than the ligand (INH) drug and its Fe (II) complex. Furthermore, elemental analysis and atomic absorption of all complexes were conducted for the determination of metal to ligand ratio. PMID- 29188777 TI - The role of Glutathione, Cysteine and D-Penicillamine in exchanging Palladium and Vanadium metals from albumin metal complex. AB - Thiol groups are extensively present across biological systems being found in range of small molecules (e.g. Glutathione, Homo-cysteine) and proteins (e.g. albumin, haemo-globin). Albumin is considered to be a major thiol containing protein present in circulating Plasma. Albumin contains a single thiolate group located at cysteine-34(cys-34) at its active site. Albumin also binds a wide variety of metals and metals complexes at various sites around the protein. Usually heavy metals are preferentially attached with the thiol group of albumin. The binding of heavy metals at cys-34 provides a mechanism by which the residence time of potentially toxic species in the body can be increased. In this research we have assessed the oxidative modification of and metal binding capacity of cys 34 with heavy metals Palladium and Vanadium to investigate the ease with which it is possible to effect disulfide-thiol exchange at this sites/or remove a metal bound at this position. Both the metals were treated with albumin and then the albumin metals (Pd and V) complexes were treated with small thoil molecules like Glutathione, Cysteine and D-Penicillamine. Our finding showed that the albumin thiol group retained the metals with itself by forming some strong bonding with the Thiols group, it is concluded from this finding that if by chance both the metals enter the living system; strongly disturb the chemistry and physiological function of this bio-molecule. PMID- 29188778 TI - Cytotoxic and acute toxicity studies of isoniazid derivatives. AB - Cancer is ultimately the result of cells that hysterically grow and do not die. Cells can experience uncontrolled growth if there are mutations to DNA, and therefore, alterations to the genes involved in cell division. Cancer occurs when a cell's gene mutations make the cell unable to correct DNA damage and is unable to destroy itself. There are over 100 different types of cancer each classified by the type of initially affected cell. Isoniazid, a well-known antitubercular agent has been reported to exhibit some cytotoxic activity. This finding prompt us to carry out this study where isoniazid and its sixteen derivatives were studied for any possible cytotoxic activity against Human astrocytoma SNB-19 cells, human Dukes' type C colorectal adenocarcinoma HCT-15 cells, human Dukes' type D colorectal adenocarcinoma COLO-205 cells, and human prostate adenocarcinoma (grade IV) PC-3 cells. Among the test compounds, SN-07 (a phenacyl derivative with para phenyl substitution) demonstrated slight cytotoxic effects on two types of human colorectal adenocarcinoma cells HCT-15 and COLO-205. Moreover, the acute toxicity of the compounds was also estimated in which some compounds were evaluated with more LD50 values than isoniazid. PMID- 29188779 TI - MRSA: Prevalence and susceptibility pattern in health care setups of Karachi. AB - This assessment aims to determine the prevalence of methicillin resistance and multidrug resistance (MDR) among the clinical isolates of Staphylococcus aureus and antimicrobial susceptibility profile of methicillin resistant Staphylococcus aureus (MRSA) to the frequently prescribed antibiotics in Karachi. Isolates of MRSA, recovered from various clinical samples were included in this prospective, cross-sectional study from Jan 2015 to June 2017. Agar diffusion method was employed according to the protocols of Clinical Laboratory Standards Institute. Out of total 346 S. aureus strains, the frequency rate of MRSA was 52% (n = 180). MRSA infection was found higher among the age group 21-30 years i.e. 30% (n=54), followed by 20% (n=36) in 31-40 years. Frequency of MRSA percentage in male and female was and 70% and 30% respectively. MRSA was more frequently observed in blood 20% (n=36). MRSA showed high resistance (100%) to Oxacillin and Cefoxitin while 25% Vancomycin resistant S. aureus (VRSA) isolates and 25% Teicoplanin resistance were also reported. MRSA exhibited 16% resistance to Minocycline. It was concluded that MRSA pose a challenging threat to public health in Karachi. In addition, MDR should be periodically checked to avoid treatment failure. PMID- 29188780 TI - Dizocilpine induced psychosis-like behavior in rats: A possible animal model with full spectrum of schizophrenia. AB - Schizophrenia (SZ) is categorized as neuropsychiatric disorder with reduced lifespan and significant impairments in social and vocational functioning. One of the best proposed pharmacological animal models is dizocilpine, as it can mimic the full spectrum of schizophrenic disorder including positive and negative symptoms along with cognitive deficits. Dizocilpine is N-methyl-D-aspartate (NMDA) receptor antagonist known to induce hyper-locomotion and stereotyped behavior in rodents. Present study was designed to develop an animal model of SZ via intraperitoneal administration of dizocilpine in rats (100-150g) at a dose of 0.3 mg/kg for eight days. For the evaluation of positive symptoms, hyperlocomotor behavior was monitored. Negative symptoms were assessed by sucrose preference test (SPT) and social interaction test (SIT). Moreover, Cognitive deficits were evaluated by novel object recognition test (NORT). After behavioral assessments animals were decapitated for further evaluation of biochemical and neurochemical estimations. Present findings revealed that dizocilpine injected rats exhibited significant hyperlocomotor behavior, depressive symptoms and cognitive deficits. Results are further strengthened with a marked increase in lipid per oxidation (LPO) in brain and a decline in reduced glutathione (GSH) levels. Biogenic amine levels (Dopamine, DA; 5-hydroxytryptamine, 5-HT) were also significantly increased and decreased respectively. Thus, present findings suggest that dizocilpine can be used as one of the best drug to develop psychosis-like symptoms in rats and to develop an animal model following a short-term study. PMID- 29188781 TI - Notch1 signaling activation protected myocardium against hypoxia injury via reducing programmed cell death. AB - Programmed cell death plays an important role in cardio protection, and Notch1 was an important factor related to programmed cell death. The role of Notch1 on ischemia myocardium remains unclear.H9C2 myocardial cells were cultured with routine medium, transfected with Notch1 over expression plasmid, Notch1-siRNA overexpression plasmid and vehicle plasmid for further hypoxic experiment. Condition of hypoxic experiment was 1% oxygen centration and culturing for 12hours, then the cell proliferation activity and apoptosis rate was assessed by MTS kit and flow cytometry, respectively. The expressions of Caspase-3, Caspase-9 and Bcl-2 were determined by RT-qPCR and Western Blot, respectively. Compared with normoxia treatment, hypoxia could decrease H9C2 cell proliferation activity as well as Bcl-2 mRNA expression, and increase cell apoptosis rate as well as Caspase-3 and Caspase-9 mRNA expression. Notch1 activation could increase proliferation activity as well as Bcl-2 mRNA expression, while decrease apoptosis rate as well as Caspase-3 and Caspase-9 mRNA expression. Compared with Notch1 activation H9C2 cells, the opposite effect on programmed cell death was observed in cells with Notch1-siRNA-overexpression plasmid. Targeted activation of Notch1 gene to reduce hypoxia-induced programmed cell death in myocardial cells via up regulating the expression of Caspase-3 and Caspase-9 and inhibiting the expression of Bcl-2. PMID- 29188782 TI - Pharmacokinetic behavior of montelukast in indigenous healthy male volunteers. AB - Aim of present study was to investigate the pharmacokinetic behavior of Montelukast in the healthy male volunteers under indigenous conditions. One tablet of montelukast 10 mg was administered in each subject and blood at different time intervals. Concentration of montelukast in plasma samples was analyzed by high performance liquid chromatography method to calculate pharmacokinetic parameters. The plasma concentration of montelukast was in the range of 1.31-1.76MUg/mL at 0.5-12 hours with Cmax value of 1.59+/-0.16MUg/mL at 3.71+/-0.64 hours. These values of plasma drug concentrations were above the minimum effective concentration of montelukast during the entire study hours. Absorption and elimination half-lives of the montelukast were evaluated as 2.52+/ 0.54 hours and 2.63+/-0.35 hours, respectively. The volume of distribution and total body clearance of montelukast were investigated as 0.34+/-0.01 L/kg and 0.01+/-0.00 L/hr/kg, respectively. The pharmacokinetic parameters i.e. Cmax, AUC, t1/2, Vd and ClB of montelukast calculated in present study were found different as compared to that of the previous literature values which was due to genetic and environmental variation. PMID- 29188784 TI - [New concerns in digital age]. PMID- 29188783 TI - The Recent Emergence of Clostridium difficile Infection in Romanian Hospitals is Associated with a High Prevalence of Polymerase Chain Reaction Ribotype 027. AB - AIMS: To investigate the epidemiology of Clostridium difficile infection in Romanian hospitals. METHODS: A survey was conducted at nine hospitals throughout Romania between November 2013 and February 2014. RESULTS: The survey identified 393 patients with Clostridium difficile infection. The median age was 67 years (range: 2-94 years); 56% of patients were aged >65 years. The mean prevalence of Clostridium difficile infection was 5.2 cases per 10.000 patient-days. The highest prevalences were 24.9 and 20 per 10.000 patient-days in hospitals specializing in gastroenterology and infectious diseases, respectively. Clostridium difficile infections were health care-associated in 70.5% patients and community-acquired in 10.2%. The origin was not determined in 19.3%. Clostridium difficile infection was severe in 12.3% of patients, and the in hospital all-cause mortality was 8.8%. Polymerase chain reaction ribotype 027 had the highest prevalence in all participating hospitals and represented 82.6% of the total ribotyped isolates. The minimum inhibitory concentration of moxifloxacin was >4 MUg/mL for 59 of 80 tested isolates (73.8%). Of 59 isolates, 54 were highly resistant to moxifloxacin (minimum inhibitory concentration >=32 MUg/mL), and the majority were polymerase chain reaction ribotype 027 (p<0.0001). CONCLUSION: The ribotype 027 was the predominant cause of Clostridium difficile infections in Romania. In some specialized hospitals, the prevalence of Clostridium difficile infection was higher than the European mean prevalence, and this demonstrates the need for strict adherence to infection control programs. PMID- 29188785 TI - [Outcome after surgical resection for rectal cancer and its precursors in Landspitali University Hospital 2008-2012]. AB - BACKGROUND: Rectal cancer makes up 2-3% of all cancers in Iceland and surgery is the mainstay of its treatment. Information regarding those who undergo resection of the rectum because of rectal cancer or its precursors in Iceland today is lacking. The aim of this study was to evaluate what kind of surgical treatment rectal cancer patients receive at Landspitali University Hospital along with peri operative and long-term outcomes. METHODS: The study was retrospective. All patients undergoing total or partial resection of the rectum for rectal cancer or its precursor from 2008-2012 in Landspitali University hospital were included. Information regarding age, sex, surgery, neoadjuvant and adjuvant treatment along with reoperations and survival were gathered. RESULTS: The total number of patients included were 144. Mean age was 66 years (33-89). Neoadjuvant treatment was used in 65 (45%) cases. Most of the patients (65%) underwent anterior resection of the rectum, 21% abdominoperineal resection, 11% Hartmann's procedure and 3% other surgery. Majority of the patients had a cancer diagnoses (88%) but 12% had dysplastic adenomas. An anastomosis was made in 67% of cases, others (33%) got a permanent stoma. Reoperation rate within 30 days was 12%. Thirty day and 1 year mortality were 0.7% and 6.2% respectively. Average follow up time was 56 months (1-98). Local recurrence rate was 7,1%, five year survival rate was 77%. CONCLUSION: The surgical treatment for rectal cancer in Landspitali is up to international standard. Perioperative and long-term outcomes are similar to what other authors have reported. PMID- 29188786 TI - [The diversion of prescribed stimulant medications of 10th graders in Iceland]. AB - INTRODUCTION: ADHD is a neurodevelopmental disorder that usually surfaces before seven years of age. Stimulants are commonly used medications for the treatment of this disorder in Iceland, but they carry with them a significant risk of both abuse and diversion - i.e. when it is used by an individual other than it was prescribed for by a physician. The purpose of this study was to estimate the prevalence of diversion amongst Icelandic adolescents. MATERIAL AND METHODS: This study is based on data collected in the Icelandic portion of the European School Survey Project on Alcohol and Other Drugs (ESPAD) focused on the drug and alcohol use of 10th graders in Europe. RESULTS: Of the 2,306 students that participated in the study 91% (2,098) claimed they had never been prescribed stimulant medications while 9% (208) claimed they had. Boys were twice as likely to get a stimulant prescription compared to girls. Almost 18% of the participants that had been prescribed simulants said they had at some point in time diverted their stimulant medication. CONCLUSION: The diversion of stimulants by 10th graders in Iceland is quite common compared to studies from other countries where the prevalence is closer to 5-10%. These findings demonstrate the importance of carefully overseeing stimulant use of adolescents, for the benefit of both those who divert as well as those diverted to. PMID- 29188787 TI - [Medical practice, magic and religion - conjunction and development before and after Reformation]. AB - The conjunction between medical practice, religion and magic becomes rather visible when one peers into old scripts and ancient literature. Before the foundation and diffusion of universities of the continent, the european convents and cloisters were the centers of medical knowl-edge and -practice for centuries. Alongside the scholarly development of medical science, driven from the roots of the eldest scholarly medicial practice, the practice of folk-medicin flourished and thrived all over Europe, not least the herbal-medicine which is the original form and foundation for modern pharmacy. This article deals with the conjunction of religion, magic and medical practice in ancient Icelandic sources such as the Old-Norse literature, medical-scripts from the 12th - 15th century Iceland, and not least the Icelandic magical-scripts (galdrakver) of the 17th century. The last mentioned documents were used as evidence in several witch-trials that led convicted witches to suffer executions at the stake once the wave of European witch-persecutions had rushed ashore in 17th century Iceland. These sources indicate a decline of medical knowledge and science in the 16th and 17th century Iceland, the medical practice being rather undeveloped at the time - in Iceland as in other parts of Europe - there-fore a rather unclear margin between "the learned and the laymen". While common people and folk-healers were convicted as witches to suffer at the stake for possession of magical scripts and healing books, some scholars of the state of Danmark were practicing healing-methods that deserve to be compared to the activities of the former ones. That comparison raises an inevitable question of where to draw the line between the learned medical man and the magician of 17th century Iceland, that is between Magic and Science. PMID- 29188789 TI - From Mn3O4/MnO core-shell nanoparticles to hollow MnO: evolution of magnetic properties. AB - Manganese oxide nanoparticles (MNOPs), when dispersed in a water solution, show a magnetic behavior that drastically changes after an aging process. In this paper, the variation in the magnetic properties has been correlated with the structural evolution of the nanoparticles: in particular, the as prepared Mn3O4/MnO core/shell system manifests a low temperature magnetization reversal that is strongly affected by the presence of the MnO shell and, in particular, by the existence of a frustrated interfacial region playing a key role in determining the low temperature irreversibility, the finite coercivity slightly above the Curie temperature of the Mn3O4 phase and the horizontal displacement of the FC hysteresis loop. On the other hand, the magnetic behavior of the aged system results dominated by the presence of Mn3O4 whose highly anisotropic character (i.e. high coercivity and high magnetization remanence) is attributed to the presence of a large fraction of surface spins. Such a result is consistent with the structural evolution, from core/shell to hollow nanoparticles, as shown by TEM observation. PMID- 29188790 TI - IRPA Consultation: is the system of protection 'fit for purpose' and can it be readily communicated? Views of the radiation protection professionals. AB - The system of protection, which provides the basic underpinning philosophy and principles for radiation protection, is constantly evolving in the light of developing scientific understanding and practical experience. Over recent times there has been significant learning from experiences relating to the Fukushima accident, and there is also increasing recognition of the importance of enhancing public understanding of radiation and risk. The practical application of radiation protection is undertaken by thousands of practitioners around the world, and it is IRPA's task to ensure that this experience is fed back for the benefit of all. This Memorandum reports the outcome of IRPA's consultation on the system of protection. The principal issues raised in the consultation include general perceptions of the system, risk uncertainties at low dose, the context of natural background exposure, dose limits and limitation, ALARA and reasonableness, and public understanding and communication of radiation and risk. PMID- 29188788 TI - Mechanistic insights of the Min oscillator via cell-free reconstitution and imaging. AB - The MinD and MinE proteins of Escherichia coli self-organize into a standing-wave oscillator on the membrane to help align division at mid-cell. When unleashed from cellular confines, MinD and MinE form a spectrum of patterns on artificial bilayers-static amoebas, traveling waves, traveling mushrooms, and bursts with standing-wave dynamics. We recently focused our cell-free studies on bursts because their dynamics recapitulate many features of Min oscillation observed in vivo. The data unveiled a patterning mechanism largely governed by MinE regulation of MinD interaction with membrane. We proposed that the MinD to MinE ratio on the membrane acts as a toggle switch between MinE-stimulated recruitment and release of MinD from the membrane. In this review, we summarize cell-free data on the Min system and expand upon a molecular mechanism that provides a biochemical explanation as to how these two 'simple' proteins can form the remarkable spectrum of patterns. PMID- 29188791 TI - Block matching sparsity regularization-based image reconstruction for incomplete projection data in computed tomography. AB - In medical imaging many conventional regularization methods, such as total variation or total generalized variation, impose strong prior assumptions which can only account for very limited classes of images. A more reasonable sparse representation frame for images is still badly needed. Visually understandable images contain meaningful patterns, and combinations or collections of these patterns can be utilized to form some sparse and redundant representations which promise to facilitate image reconstructions. In this work, we propose and study block matching sparsity regularization (BMSR) and devise an optimization program using BMSR for computed tomography (CT) image reconstruction for an incomplete projection set. The program is built as a constrained optimization, minimizing the L1-norm of the coefficients of the image in the transformed domain subject to data observation and positivity of the image itself. To solve the program efficiently, a practical method based on the proximal point algorithm is developed and analyzed. In order to accelerate the convergence rate, a practical strategy for tuning the BMSR parameter is proposed and applied. The experimental results for various settings, including real CT scanning, have verified the proposed reconstruction method showing promising capabilities over conventional regularization. PMID- 29188792 TI - Helical edge states in silicene and germanene nanorings in perpendicular magnetic field. AB - Due to nonzero intrinsic spin-orbit interaction in buckled honeycomb crystal structures, silicene and germanene exhibit interesting topological properties, and are therefore candidates for the realization of the quantum spin Hall effect. We employ the Kane-Mele model to investigate the electron states in hexagonal silicene and germanene nanorings having either zigzag or armchair edges in the presence of a perpendicular magnetic field. We present results for the energy spectra as function of magnetic field, the electron density of the spin-up and spin-down states in the ring plane, and the calculation of the probability current density. The quantum spin Hall phase is found at the edges between the nontrivial topological phase in silicene and germanene and vacuum. We demonstrate that the helical edge states in zigzag silicene and germanene nanorings can be qualitatively well understood by means of classical magnetic moments. However, this is not the case for comparable-sized armchair nanorings, where the eigenfunctions spread throughout the ring. Finally, we note that the energy spectra of silicene and germanene nanorings are similar and that the differences between the two are mainly related to the difference in magnitude of the spin orbit coupling.

AB - Rabies is a life-threatening neglected tropical disease: tens of thousands of cases are reported annually in endemic countries (mainly in Africa and Asia), although the actual numbers are most likely underestimated. Rabies is a zoonotic disease that is caused by infection with viruses of the Lyssavirus genus, which are transmitted via the saliva of an infected animal. Dogs are the most important reservoir for rabies viruses, and dog bites account for >99% of human cases. The virus first infects peripheral motor neurons, and symptoms occur after the virus reaches the central nervous system. Once clinical disease develops, it is almost certainly fatal. Primary prevention involves dog vaccination campaigns to reduce the virus reservoir. If exposure occurs, timely post-exposure prophylaxis can prevent the progression to clinical disease and involves appropriate wound care, the administration of rabies immunoglobulin and vaccination. A multifaceted approach for human rabies eradication that involves government support, disease awareness, vaccination of at-risk human populations and, most importantly, dog rabies control is necessary to achieve the WHO goal of reducing the number of cases of dog-mediated human rabies to zero by 2030. PMID- 29188796 TI - In situ regeneration of retinal pigment epithelium by gene transfer of E2F2: a potential strategy for treatment of macular degenerations. AB - The retinal pigment epithelium (RPE) interacts closely with photoreceptors to maintain visual function. In degenerative diseases such as Stargardt disease and age-related macular degeneration, the leading cause of blindness in the developed world, RPE cell loss is followed by photoreceptor cell death. RPE cells can proliferate under certain conditions, suggesting an intrinsic regenerative potential, but so far this has not been utilised therapeutically. Here, we used E2F2 to induce RPE cell replication and thereby regeneration. In both young and old (2 and 18 month) wildtype mice, subretinal injection of non-integrating lentiviral vector expressing E2F2 resulted in 47% of examined RPE cells becoming BrdU positive. E2F2 induced an increase in RPE cell density of 17% compared with control vector-treated and 14% compared with untreated eyes. We also tested this approach in an inducible transgenic mouse model of RPE loss, generated through activation of diphtheria toxin-A gene. E2F2 expression resulted in a 10-fold increase in BrdU uptake and a 34% increase in central RPE cell density. Although in mice this localised rescue is insufficiently large to be demonstrable by electroretinography, a measure of massed retinal function, these results provide proof-of-concept for a strategy to induce in situ regeneration of RPE for the treatment of RPE degeneration. PMID- 29188798 TI - Capsaicin enhances the antitumor activity of sorafenib in hepatocellular carcinoma cells and mouse xenograft tumors through increased ERK signaling. AB - Sorafenib, a small inhibitor of tyrosine protein kinases, is currently the standard chemotherapy drug for the treatment of advanced hepatocellular carcinoma (HCC). Although sorafenib improves the survival of HCC patients, its efficacy is not optimal and requires further improvement. Capsaicin, the major active component of chili peppers from the genus Capsicum, is not only the agonist of TRPV1 channel, but also displays antitumor activity and enhances the sensitivity of cancer cells to cytotoxic drugs. In this study, we investigated the antitumor effects of combined sorafenib and capsaicin on HCC cells in vitro and xenograft tumors. Treatment with capsaicin alone dose-dependently inhibited the proliferation of the HCC cell lines PLC/PRF/7, HuH7 and HepG2 with IC50 values of 137, 108 and 140.7 MUmol/L, respectively. No obvious expression of TRPV1 channel was detected in the 3 HCC cell lines and TRPV1 channel blockers did not alleviate the cytotoxicity of capsaicin. By contrast, combining capsaicin and sorafenib significantly enhanced the suppression on cell proliferation, achieving a high level synergistic effect (inhibition rates over 50%) and promoting HCC cell apoptosis. In nude mice with PLC/PRF/5 xenografts, combined administration of capsaicin and sorafenib significantly enhanced the suppression on tumor growth without apparent gross toxicity compared to either agent alone. Mechanistically, capsaicin (10-200 MUmol/L) dose-dependently increased the levels of phosphorylated ERK (p-ERK) in PLC/PRF/5 cells, thus leading to enhanced sorafenib sensitivity and a synergistic suppression on the tumor cells. Taken together, our results suggest that capsaicin-increased phosphorylation of ERK contributes to the enhanced antitumor activity of sorafenib, and capsaicin may be useful in improving the efficacy of sorafenib for the treatment of HCC. PMID- 29188800 TI - Chip-based digital PCR as a novel detection method for quantifying microRNAs in acute myocardial infarction patients. AB - miRNAs have shown promise as potential biomarkers for acute myocardial infarction (AMI). However, the current used quantitative real-time PCR (qRT-PCR) allows solely for relative expression of nucleic acids and it is susceptible to day-to day variability, which has limited the validity of using the miRNAs as biomarkers. In this study we explored the technical qualities and diagnostic potential of a new technique, chip-based digital PCR, in quantifying the miRNAs in patients with AMI and ischaemia-reperfusion injury (I/R). In a dilution series of synthetic C.elegans-miR-39, chip-based digital PCR displayed a lower coefficient of variation (8.9% vs 46.3%) and a lower limit of detection (0.2 copies/MUL vs 1.1 copies/MUL) compared with qRT-PCR. In the serum collected from 24 patients with ST-elevation myocardial infarction (STEMI) and 20 patients with stable coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI), we used qRT-PCR and multiplexed chip-based digital PCR to quantify the serum levels of miRNA-21 and miRNA-499 as they have been validated in AMI in prior studies. In STEMI, I/R injury was assessed via measurement of ST segment resolution (ST-R). Chip-based digital PCR revealed a statistical significance in the difference of miR-21 levels between stable CAD and STEMI groups (118.8 copies/MUL vs 59 copies/MUL; P=0.0300), whereas qRT-PCR was unable to reach significance (136.4 copies/MUL vs 122.8 copies/MUL; P=0.2273). For miR 499 levels, both chip-based digital PCR and qRT-PCR revealed statistically significant differences between stable CAD and STEMI groups (2 copies/MUL vs 8.5 copies/MUL, P=0.0011; 0 copies/MUL vs 19.4 copies/MUL; P<0.0001). There was no association between miR-21/499 levels and ST-R post-PCI. Our results show that the chip-based digital PCR exhibits superior technical qualities and promises to be a superior method for quantifying miRNA levels in the circulation, which may become a more accurate and reproducible method for directly quantifying miRNAs, particularly for use in large multi-centre clinical trials.

AB - Among the somatostatin analogues, octreotide (OCT) is the most commonly used in clinic via intravenous or subcutaneous injection to treat various diseases caused by increased secretion of growth hormone, gastrin or insulin. In order to assesse the feasibility of developing oral formulations of OCT, we conducted systematical pharmacokinetic and pharmacodynamic analyses of OCT in several animal models. The pharmacokinetic studies in rats showed that intragastric administration of OCT had extremely low bioavailability (<0.5%), but it could specifically distribute to the gastric mucosa due to the high expression of somatostatin receptor 2 (SSTR2) in the rat stomach. The pharmacodynamic studies revealed that intragastric administration of OCT dose-dependently protected against gastric mucosal injury (GMI) in mice with WIRS-induced mouse gastric ulcers, which were comparable to those achieved by intravenous injection of OCT, and this effect was markedly attenuated by co-administration of CYN-154806, an antagonist of SSTR2. In pyloric ligation-induced ulcer mice, we further demonstrated that OCT significantly reduced the secretion of gastric acid via down-regulating the level of gastrin, which was responsible for the protective effect of OCT against GMI. Overall, we have provided pharmacokinetic and pharmacodynamic evidence for the feasibility of developing an oral formulation of OCT. Most importantly, the influence of SSTR2 on the pharmacokinetics and pharmacodynamics of OCT suggested that an oral formulation of OCT might be applicable for other clinical indications, including neuroendocrine neoplasms and pituitary adenoma due to the overexpression of SSTR2 on these tumor cells. PMID- 29188799 TI - Computational insights into the G-protein-biased activation and inactivation mechanisms of the MU opioid receptor. AB - The MU opioid receptor (OR), a member of the class A subfamily of G-protein coupled receptors (GPCRs), is a major target for the treatment of pain. G-protein biased MU-OR agonists promise to be developed as analgesics. Thus, TRV130, the first representative MU-OR ligand with G-protein bias, has entered into phase III clinical trials. To identify the detailed G-protein-biased activation and inactivation mechanisms of the MU-OR, we constructed five MU-OR systems that were in complexes with the G-protein-biased agonists TRV130 and BU72, the antagonists beta-FNA and naltrexone, as well as the free receptor. We performed a series of conventional molecular dynamics simulations and analyses of G-protein-biased activation and inactivation mechanisms of MU-OR. Our results, together with previously reported mutation results, revealed the operating mode of the activation switch composed of residues W6.48 and Y7.43 (Ballesteros/Weinstein numbering), the activity of which was responsible for down- and up-regulation, respectively, of the beta-arrestin signaling, which in turn affected G-protein biased activation of MU-OR. TRV130 was found to stabilize W6.48 by interacting with Y7.43. In addition, we obtained useful information regarding MU-OR-biased activation, such as strong stabilization of W7.35 through a hydrophobic ring interaction in the TRV130 system. These findings may facilitate understanding of MU-OR biased activation and the design of new biased ligands for GPCRs. PMID- 29188804 TI - Device therapy: Interatrial shunt device for HFpEF. PMID- 29188802 TI - The LPI/GPR55 axis enhances human breast cancer cell migration via HBXIP and p MLC signaling. AB - The G protein-coupled receptor 55 (GPR55) is expressed in multiple tissues, and has been implicated in cancer pathogenesis, but little is known about its role in the migratory behavior of cancer cells, particularly breast cancer cells. In this study we first showed that GPR55 expression levels in 38 metastatic lymph nodes of breast cancer patients were profoundly elevated, and were positively associated in human breast cancer cells with their migratory ability. Moreover, the plasma levels of GPR55 endogenous agonist L-a-lysophosphatidylinositol (LPI) were significantly increased in breast cancer patients compared with healthy individuals. In human breast cancer LM-MCF-7 and MDA-MB-231 cells, treatment with LPI (2.5 MUmol/L) significantly increased filopodia formation and resulted in cell migration, which could be blocked either by the GPR55 antagonist CID16020046 or by siRNA-mediated GPR55 knockdown. Furthermore, dual-luciferase report gene assays showed that GPR55 upregulated HBXIP at the promoter; GPR55 expression levels were positively correlated with HBXIP expression levels in breast cancer tissues and 8 breast cancer cell lines. We also showed that the LPI/GPR55 axis promoted the migration of breast cancer cells via two mutually exclusive pathways - the HBXIP/p-ERK1/2/Capn4 and MLCK/MLC signaling pathways. In xenograft nude mouse model, loss of GPR55 mainly affected breast cancer cell metastasis and the formation of metastatic foci. Thus, GPR55 is involved in the migratory behavior of human breast cancer cells and could serve as a pharmacological target for preventing metastasis.

PMID- 29188803 TI - Activation of human smooth muscle BK channels by hydrochlorothiazide requires cell integrity and the presence of BK beta1 subunit. AB - Thiazide-like diuretics are the most commonly used drugs to treat arterial hypertension, with their efficacy being linked to their chronic vasodilatory effect. Previous studies suggest that activation of the large conductance voltage and Ca2+-dependent K+ (BK) channel (Slo 1, MaxiK channel) is responsible for the thiazide-induced vasodilatory effect. But the direct electrophysiological evidence supporting this claim is lacking. BK channels can be associated with one small accessory beta-subunit (beta1-beta4) that confers specific biophysical and pharmacological characteristics to the current phenotype. The beta1-subunit is primarily expressed in smooth muscle cells (SMCs). In this study we investigated the effect of hydrochlorothiazide (HCTZ) on BK channel activity in native SMCs from human umbilical artery (HUASMCs) and HEK293T cells expressing the BK channel (with and without the beta1-subunit). Bath application of HCTZ (10 MUmol/L) significantly augmented the BK current in HUASMCs when recorded using the whole cell configurations, but it did not affect the unitary conductance and open probability of the BK channel in HUASMCs evaluated in the inside-out configuration, suggesting an indirect mechanism requiring cell integrity. In HEK293T cells expressing BK channels, HCTZ-augmented BK channel activity was only observed when the beta1-subunit was co-expressed, being concentration-dependent with an EC50 of 28.4 MUmol/L, whereas membrane potential did not influence the concentration relationship. Moreover, HCTZ did not affect the BK channel current in HEK293T cells evaluated in the inside-out configuration, but significantly increases the open probability in the cell-attached configuration. Our data demonstrate that a beta1-subunit-dependent mechanism that requires SMC integrity leads to HCTZ-induced BK channel activation. PMID- 29188806 TI - Obesity: Bariatric surgery helps BP control.

PMID- 29188817 TI - Dietary sugar intake was associated with increased body fatness but decreased cardiovascular mortality in Chinese elderly: an 11-year prospective study of Mr and Ms OS of Hong Kong. AB - BACKGROUND/OBJECTIVES: Epidemiological studies suggest that sugar intake contributes to weight gain and increased risk of cardiovascular diseases (CVDs). However, this association is largely undefined in the elderly population. Our aim was to investigate the effect of sugar consumption on the subsequent changes in body fatness and CVD mortality in Chinese elderly. METHODS: A total of 2000 men and 2000 women aged ?65 years were recruited from 2001 to 2003. Dietary sugar intake was estimated based on a validated 329-item food frequency questionnaire and a local sugar database. Adiposity was measured using dual-energy X-ray absorptiometry at baseline and follow-up after 4 years. Mortality was ascertained by local death registry until March 2014. Multivariable linear and Cox regression were conducted to evaluate the association of sugar consumption on the changes in body fatness and CVD mortality. RESULTS: A total of 174 CVD deaths were documented within the total 37 999 person-years' follow-up. Significant positive association between sugar intake and increase in body fatness at follow-up after 4 years was found in men but not in women. After adjustment for potential confounders, men who consumed 1% increase in added sugar had an increase in whole body fat by 0.043 kg (P=0.006), central fat by 0.029 kg (P=0.016) and peripheral fat by 0.026 kg (P=0.006). However, in both genders, after an average of 11.1 year follow-up, compared with the lowest quintile, the highest intakes of added sugar were associated with significantly lowered CVD mortality by 74.9% (hazard ratio (HR) (95% confidence interval (CI)): 0.251(0.070, 0.899)) in a dose response manner (Ptrend=0.011). This association was attenuated to non significance by further adjustment of the change in body fatness (Ptrend=0.055). CONCLUSIONS: Thus higher sugar intake of the Chinese elderly was associated with increased adiposity in men but decreased CVD mortality. The current World Health Organization recommendation for the elderly should be reviewed. PMID- 29188819 TI - Colonic Bacteroides are positively associated with trabecular bone structure and programmed by maternal vitamin D in male but not female offspring in an obesogenic environment. AB - BACKGROUND/OBJECTIVES: The gut microbiota is determined early in life, possibly including pregnancy. Pioneering data suggest vitamin D, a nutrient important for bone health, affects this microbiota. We found that high maternal vitamin D lowered circulating lipopolysaccharide (LPS), improved intestinal barrier and bone health in male but not female offspring in an obesogenic environment. This study determined if high maternal dietary vitamin D programs Bacteroides and Prevotella and whether this associates with bone mineral content, density and structure of male and female adult offspring fed an obesogenic diet. METHODS: C57BL/6J females received an AIN93G diet with high or low vitamin D from before mating until weaning. Post-weaning, male and female offspring remained on their respective vitamin D level or were switched and fed a high fat and sucrose diet until killing (age 7 months). Bacteroides and Prevotella were quantified in dams' feces and offspring colonic contents. LPS concentrations, bone mineral density and content, strength and structure data were integrated from our previous studies in the same mice. Spearman correlations were completed between Bacteroides and LPS, and bone outcomes. RESULTS: There was a maternal vitamin D effect on colonic Bacteroides but not Prevotella (dam diet: <0.001 and 0.735) in adult male offspring, independent of dams fecal Bacteroides before birth (P=0.998). In males, but not females, Bacteroides correlated with LPS (r=-0.488, P=0.018), trabecular femur peak load (r=0.362, P=0.033), vertebral trabecular separation (r=-0.605, P=0.006), trabecular number (r=0.614, P=0.005) and bone volume fraction (r=0.549, P=0.015). CONCLUSIONS: Dietary vitamin D programs Bacteroides in male adult offspring only, which correlated negatively with systemic inflammation and positively with bone strength and structure. This may have implications on maternal diet and nutritional guidelines targeting sexes in a different manner. PMID- 29188818 TI - No evidence of white adipocyte browning after endurance exercise training in obese men. AB - BACKGROUND/OBJECTIVES: The phenomenon of adipocyte 'beiging' involves the conversion of non-classic brown adipocytes to brown-like adipose tissue with thermogenic, fat-burning properties, and this phenomenon has been shown in rodents to slow the progression of obesity-associated metabolic diseases. Rodent studies consistently report adipocyte beiging after endurance exercise training, indicating that increased thermogenic capacity in these adipocytes may underpin the improved health benefits of exercise training. The aim of this study was to determine whether prolonged endurance exercise training induces beige adipogenesis in subcutaneous adipose tissues of obese men. SUBJECTS/METHODS: Molecular markers of beiging were examined in adipocytes obtained from abdominal subcutaneous (AbSC) and gluteofemoral (GF) subcutaneous adipose tissues before and after 6 weeks of endurance exercise training in obese men (n=6, 37.3+/-2.3 years, 30.1+/-2.3 kg m-2). RESULTS: The mRNAs encoding the brown or beige adipocyte-selective proteins were very lowly expressed in AbSC and GF adipose tissues and exercise training did not alter the mRNA expression of UCP1, CD137, CITED, TBX1, LHX8 and TCF21. Using immunohistochemistry, neither multilocular adipocytes, nor UCP1 or CD137-positive adipocytes were detected in any sample. MicroRNAs known to regulate brown and/or beige adipose development were highly expressed in white adipocytes but endurance exercise training did not impact their expression. CONCLUSIONS: The present study reaffirms emerging data in humans demonstrating no evidence of white adipose tissue beiging in response to exercise training, and supports a growing body of work demonstrating divergence of brown/beige adipose location, molecular characterization and physiological function between rodents and humans.

PMID- 29188820 TI - Identification of novel alleles associated with insulin resistance in childhood obesity using pooled-DNA genome-wide association study approach. AB - BACKGROUND: Recently, we witnessed great progress in the discovery of genetic variants associated with obesity and type 2 diabetes (T2D), especially in adults. Much less is known regarding genetic variants associated with insulin resistance (IR). We hypothesized that novel IR genes could be efficiently detected in a population of obese children and adolescents who may not exhibit comorbidities and other confounding factors. OBJECTIVES: This study aimed to determine whether a genome-wide association study (GWAS), using a DNA-pooling approach, could identify novel genes associated with IR. SUBJECTS: The pooled-DNA GWAS analysis included Slovenian obese children and adolescents with and without IR matched for body mass index, gender and age. A replication study was conducted in another independent cohort with or without IR. METHODS: For the pooled-DNA GWAS, we used HumanOmni5-Quad SNP array (Illumina). Allele frequency distributions were compared with modified t-tests and chi2-tests and ranked using PLINK. Top single nucleotide polymorphisms (SNPs) were validated using individual genotyping by high-resolution melting analysis and TaqMan assay. RESULTS: We identified five top-ranking SNPs from the pooled-DNA GWAS analysis within the ECE1, IL1R2, GNPDA1, HLA-J and PYGB loci. All except SNP rs9261108 (HLA-J locus) were confirmed in the validation phase using individual genotyping. The SNP rs2258617 within PYGB remained statistically significant for both recessive and additive models in both cohorts and in a merged analysis of both cohorts and present the strongest novel candidate gene for IR. CONCLUSION: We report for the first time a pooled-DNA GWAS approach to identify five novel SNPs or genes for IR in a paediatric population. The four loci confirmed in the second validation phase study warrant further studies, especially the strongest SNP rs2258617 within PYGB, and provide targets for further basic research of IR mechanisms and for the development of potential new IR and T2D therapies.

PMID- 29188825 TI - Ultrafast dynamics of ionic liquids in colloidal dispersion. AB - Ionic liquid (IL)-surfactant complexes have significance both in applications and fundamental research, but their underlying dynamics are not well understood. We apply polarization-controlled two-dimensional infrared spectroscopy (2D-IR) to study the dynamics of [BMIM][SCN]/surfactant/solvent model systems. We examine the effect of the choice of surfactants and solvent, and the IL-to-surfactant ratio (W-value), with a detailed analysis of the orientation and structural dynamics of each system. Different surfactants create very different environments for the entrapped ILs, ranging from a semi-static micro-environment to a fluxional environment that evolves even faster than the bulk IL. The oil-phase also clearly affects the microscopic dynamics. The anisotropy decay for entrapped ILs completes within 10 ps, which is similar to free thiocyanate ion in water, while a significant reorientation-induced spectral diffusion (RISD) effect is observed. The entrapped ionic liquid are highly dynamic for all W-values, and no core-shell structure is observed. We hypothesize that, instead of an ionic liquid reverse micelle (IL-RM), the microscopic structure of this system is small colloidal dispersions or pairs of IL and surfactants. A detailed analysis of the polarization-controlled 2D-IR spectra of AOT system reveals a potential ion exchange mechanism.

AB - An organogelator based on a N,N'-substituted H-bonding perylenebisimide (PBI-C10) self-assembles to form either a green J-type (form I) or a red H-type (form II) aggregate structure. The molecular packing of both polymorphs was determined from a combination of Transmission Electron Microscopy (TEM) (low dose electron diffraction and high resolution), Grazing incidence X-ray diffraction and polarized infrared spectroscopy. To that aim, highly oriented films have been prepared by mechanical rubbing at controlled film temperature and DFT calculations were performed to identify representative vibrational IR bands and their associated polarizations. H-Bonding between amides generates either a rectangular columnar phase (form I) in the dried gel or a hexagonal packing of supramolecular 21/1 helices with a long period of 97 A (form II) in annealed thin films. In aligned films of form I, polarized FTIR spectroscopy helps determine the orientation of both intermolecular H-bonds and the PBI core with respect to the substrate. In form II, PBI-C10 molecules assemble into pairs to form off centered 21/1 helices whose helical axis is made of strongly H-bonded amides. TEM investigations show that three 21/1 helices are packed in a frustrated trigonal structure formed by H-bonding. The Form I -> Form II transformation implies a redistribution of a single population of strong intra-columnar H-bonds between amides in form I to a mixture of strong and weak H-bonds in the supramolecular helices, the strong H-bonds forming the spine of the helices. PMID- 29188828 TI - Using ZnO-Cr2O3-ZnO heterostructures to characterize polarization penetration depth through non-polar films. AB - The ability to affect the surface properties of non-polar Cr2O3 films through polar ZnO(0001) and (0001[combining macron]) supports was investigated by characterizing the polarity of ZnO films grown on top of the Cr2O3 surfaces. The growth and geometric and electronic structures of the ZnO films were characterized with X-ray photoelectron spectroscopy, ultra-violet photoelectron spectroscopy, reflection high-energy electron diffraction, low-energy electron diffraction, and X-ray diffraction. The ZnO growth mode was Stranski-Krastanov, which can be attributed to the ZnO layers initially adopting a non-polar structure with a lower surface tension before transitioning to the polar bulk structure with a higher surface energy. A similar result has been reported for ZnO growth on alpha-Al2O3(0001), which is isostructural with Cr2O3. The polarity of the added ZnO layer was determined by examining the surface morphology following wet chemical etching with atomic force microscopy and by characterizing the surface reactivity via temperature-programmed desorption of alcohols, which strongly depends on the ZnO polarization direction. Consistent with prior work on ZnO growth on bulk Cr2O3(0001), both measurements indicate that thick Cr2O3 layers support ZnO(0001[combining macron]) growth regardless of the underlying ZnO substrate polarization; however, the polarization direction of ZnO films grown on Cr2O3 films less than three repeat units thick follows the direction of the underlying substrate polarization. These findings show that it is possible to manipulate the surface properties of non-polar materials with a polar substrate, but that the effect does not penetrate past just a couple of repeat units. PMID- 29188829 TI - Solvent effects on excitation energies obtained using the state-specific TD-DFT method with a polarizable continuum model based on constrained equilibrium thermodynamics. AB - Nonequilibrium solvation effects need to be treated properly in the study of electronic absorption processes of solutes since solvent polarization is not in equilibrium with the excited-state charge density of the solute. In this work, we developed a state specific (SS) method based on the novel nonequilibrium solvation model with constrained equilibrium manipulation to account for solvation effects in electronic absorption processes. Time-dependent density functional theory (TD-DFT) is adopted to calculate electronic excitation energies and a polarizable continuum model is employed in the treatment of bulk solvent effects on both the ground and excited electronic states. The equations based on this novel nonequilibrium solvation model in the framework of TDDFT to calculate vertical excitation energy are presented and implemented in the Q-Chem package. The implementation is validated by comparing reorganization energies for charge transfer excitations between two atoms obtained from Q-Chem and those obtained using a two-sphere model. Solvent effects on electronic transitions of coumarin 153 (C153), acetone, pyridine, (2E)-3-(3,4-dimethoxyphenyl)-1-(2 hydroxyphenyl)prop-2-en-1-one (DMHP), and uracil in different solvents are investigated using the newly developed code. Our results show that the obtained vertical excitation energies as well as spectral shifts generally agree better with the available experimental values than those obtained using the traditional nonequlibrium solvation model. This new model is thus appropriate to study nonequilibrium excitation processes in solution. PMID- 29188830 TI - Synthesis and applications of rhodium porphyrin complexes. AB - Organotransition metal complexes capable of forming metalloradicals have been an intriguing subject of study for the past fifty years. Of these, rhodium porphyrin complexes have proven particularly interesting due to their straightforward synthesis and unique reactivity; indeed, these complexes are responsible for some highly influential transformations of organic compounds, including rare C-H and C C bond activations. The complexity and selectivity of rhodium porphyrins has been attractive for catalytic transformations, with specific interest in their usage for selective carbon monoxide reduction for fuel cell applications. This review will highlight historical and modern syntheses of rhodium porphyrins, as well as their respective reactions with small molecules and applications therein. The discussion will be limited to rhodium porphyrins consisting of four pyrrolic rings bridged with four methine units.

AB - Spin filtering materials are of great current interest in part due to their applications in molecular electronics. In this study, we carried out a theoretical investigation on the charge transport properties of transition metal (TM) dithiolene complexes with TM = Ni, Fe and Mn by using non-equilibrium Green's function/density functional theory (NEGF-DFT) methods. The characteristics of current-voltage and spin-resolved transmission spectra pointed out that Ni complexes are non-polarized, while Fe and Mn complexes exhibit high polarization and can be regarded as excellent candidates for spin-filtering materials with high spin-filtering efficiency. These differences were rationalized on the basis of electron delocalization over the molecular junction of the partial distribution of alpha- and beta-spin molecular projected self consistent Hamiltonian (MPSH) orbitals, and also the first eigenchannels of molecular junctions. PMID- 29188832 TI - The aromatic character of [10]annulenes and dicupra[10]annulenes from current density calculations. AB - We have investigated the aromatic properties of seven low-lying isomers of [10]annulene and of the recently synthesized dicupra[10]annulene compounds that were crystallised with two or four lithium counterions (Wei et al., J. Am. Chem. Soc., 2016, 138, 60-63). The molecular structures of the [10]annulene conformers and the dicupra[10]annulenes with bulky trimethylsilyl (TMS) and phenyl groups, as well as the corresponding unsubstituted dicupra[10]annulenes were optimised using density functional theory, employing a semi-empirical dispersion correction to consider van der Waals interactions. The structures of the hydrocarbon annulenes were subsequently optimised at the SCS-MP2/def2-QZVPD level. Single point coupled-cluster calculations with explicit treatment of the electron correlation CCSD(F12)(T) were performed to obtain the relative energies of the hydrocarbon annulenes. Four of the conformations lie close in energy relative to each other. Three substituted and three unsubstituted dicupra[10]annulene structures with either four, two or no Li+ counterions were investigated. Magnetically induced current densities calculated using the GIMIC program were used for the assessment of the aromatic properties of the studied molecules. The conformations of [10]annulene with lowest energies are non-aromatic. The calculations revealed that the electron donation of the lithium atoms to the dicupra[10]annulene core significantly affects the electronic and molecular structures of the dicupra[10]annulenes. The annulene ring is non-planar for all studied dicupra[10]annulenes except for the unsubstituted one with four Li+ counterions, which was also found to be the only molecule that sustains a strong diatropic ring current around the dicupra[10]annulene ring. The other five dicupra[10]annulenes sustain very weak net ring currents and can be considered non-aromatic.

PMID- 29188834 TI - Detection of a weak ring current in a nonaromatic porphyrin nanoring using magnetic circular dichroism. AB - We compare the absorption and magnetic circular dichroism (MCD) spectra of a series of porphyrin oligomers - dimer, tetramer, and hexamer - bound in a linear or cyclic fashion. The MCD signal is extremely weak for low energy transitions in the linear oligomers, but it is amplified when the cyclic porphyrin hexamer binds a template, restricting rotational freedom. The appearance of Faraday A terms in the MCD spectra demonstrates the presence of a magnetic moment, and thus, uncompensated electronic current. The value of the excited state magnetic moment estimated from the A term is very low compared with those of monomeric porphyrins, which confirms the nonaromatic character of the cyclic array and the lack of a global ring current in the ground state of the neutral nanoring. DFT calculations predict the absorption and MCD patterns reasonably well, but fail to reproduce the MCD sign inversion observed in substituted monomeric zinc porphyrins ("soft" chromophores). Interestingly, a correct sign pattern is predicted by INDO/S calculations. Analysis of the MCD spectra of the monomeric porphyrin unit allowed us to distinguish between two close-lying lowest energy transitions, which some previous assignments placed further apart. The present results prove the usefulness of MCD not only for deconvolution and assignment of electronic transitions, but also as a sensitive tool for detecting electronic ring currents. PMID- 29188835 TI - Dynamics of transient species via anion photodetachment. AB - The dynamics of chemical reactions are often governed by transient species, including the transition state for activated bimolecular reactions. Such transient species are difficult to study experimentally, but it has proven valuable to prepare and probe transition-state dynamics by the photodetachment of anions with an equilibrium geometry similar to the neutral transition state. In this review, recent experimental advances in photoelectron and photoelectron photofragment coincidence spectroscopy are discussed, as well as the latest progress in the calculation of multidimensional potential energy surfaces and quantum dynamics calculations that have enabled an extension of studies of transition-state dynamics to increasingly multidimensional polyatomic systems. Examples of important dynamical effects such as mode specificity, tunneling, resonance and product energy disposal in reaction dynamics are discussed.

Multinuclear NMR studies permitted the first spectroscopic characterisation of the metalation products and revealed the presence of monomeric (for M = Li) contact ion pairs in solution. NMR spectroscopic evidence that the ions in each pair interact via LiP- rather than LiH3B-interactions as had been inferred for a Ph-substituted analogue was confirmed by DFT studies, which revealed also that the borane coordination plays a decisive role in boosting the PH-acidity of the original secondary diaminophosphane precursor. Transmetalation of the potassium and lithium diaminophosphanide-boranes with Cu(i) and Zn(ii) chlorides afforded the first functional transition metal complexes of a P-heteroatom-functionalised phosphanide-borane ligand. Both products were fully characterised. Thermolysis of the Cu-complex induced a reaction which involved transfer of an NHC ligand from the metal to the phosphorus atom and yielded a phosphaalkene NHC[double bond, length as m-dash]PH (NHC = N-heterocyclic carbene) as the major phosphorus containing product.

AB - The highly stereoselective intermolecular all-carbon [4+2] annulation between in situ generated acyclic dienolates and alpha,beta-unsaturated acyl azoliums is disclosed. The identification of 2-acyloxy-3-butenones as suitable diene precursors is the key to the success of this transformation. The corresponding highly functionalized cyclohexene products, which are inaccessible from Diels Alder reactions, were delivered with high levels of diastereo- and enantioselectivities. A series of further transformations based on the product showed the potential of this reaction.

AB - A detailed computational characterization of the one-photon absorption spectrum of a 2-((E)-2-[2,2']-bithiophenyl-5-yl-vinyl)-1-methyl-quinolinium cation in acetonitrile solution is presented. The main physico-chemical effects (solvation, vibronic progression) affecting the band position and shape are progressively introduced in the computational model, highlighting their relative role in the spectral profile. The reported results underline how an accurate reproduction of the experimental spectrum can only be obtained by going beyond oversimplified methods. Moreover, the deep interplay between the solvent effects and nuclear rearrangements permits the negative solvatochromism exhibited by hypsochromic molecules to be explained. This illustrates the potential of the computational investigation, which can shed light on the information hidden in experimental spectra. PMID- 29188841 TI - Temperature effect on the emission spectra of narrow band Mn4+ phosphors for application in LEDs. AB - Temperature dependence of the luminescence shape and decay time of narrow band Mn4+ fluoride phosphors: Rb2GeF6:Mn4+ and KNaSiF6:Mn4+ was investigated. The temperature changes in the relative intensity between the zero-phonon line and both phonon sidebands were observed in both samples. The sideband spectra consist of three lines related to interaction with three different phonon modes labeled nu3, nu4 and nu6. We present a comprehensive quantum theory which allows calculation of the luminescence intensity and the luminescence lifetime by simultaneously taking into account odd parity crystal fields, odd parity phonon modes and spin-orbit coupling. Since we include all modes, for which the respective interaction strengths and energies of the phonons are known, our approach does not involve any free parameters. We also discuss our results in relation to the temperature dependence of the lifetime of the 2Eg -> 4A2g transition, taking into account the quantum efficiency of the system and the migration of the excitation energy. The presented model is applicable to all materials doped with Mn4+ ions and also to any narrow line emitting phosphor, where a zero-phonon line and phonon structure is simultaneously observed in the emission spectrum. PMID- 29188842 TI - Multiple polarization states in symmetric ferroelectric heterostructures for multi-bit non-volatile memories. AB - Here we report a ferroelectric capacitor structure obtained by alternating ferroelectric and insulator thin-film layers which allows an increase of up to 2n polarization states, with n the number of ferroelectric layers. Four and up to eight distinct, stable and independently addressed polarization states are experimentally demonstrated in this work. The experimental findings are supported by a theoretical model based on the Landau-Ginzburg-Devonshire theory. The key parameter is the change in the strain conditions of ferroelectric layers induced by the insulating separator. Notably, the 2n increase in the storage capacity can be achieved without major changes in the present technology used for FeRAM devices. The test structures demonstrate very good memory characteristics such as retention and fatigue, opening the way towards the design of high density ferroelectric memories. PMID- 29188843 TI - Effect of suberoylanilide hydroxamic acid (SAHA) on breast cancer cells within a tumor-stroma microfluidic model. AB - Metastatic cancer is regarded as one of the largest contributors to disease related deaths worldwide. Poor patient prognosis and treatment outcome is tied to the lack of efficacious anti-cancer therapies, which is due in part to the lack of physiologically relevant in vitro screening systems that can mimic the native tumor microenvironment. Conventional drug-screening platforms, which are often used in the pharmaceutical industry, are either two-dimensional (2D) assays or three-dimensional (3D) hydrogel-based matrices that lack precise control over cell distribution, matrix architecture, and organization. Despite the significance of in vivo models, they have limitations as it is difficult to control and analyze the influence of specific variables within their tumor microenvironment. Thus, there is still a crucial need to develop tumor models that enable precise control of microenvironmental cues (e.g. matrix composition, soluble factors, cellular organization) to assess the efficacy of anti-cancer drugs. Herein, we report the development and validation of a 3D microfluidic invasion platform for anti-cancer drug studies. Our platform allowed for compartmentalization of tumor and stromal fibroblasts in a defined architecture, thereby enabling pharmacokinetic drug transport to a cell-dense tumor region. We analyzed the effect of suberoylanilide hydroxamic acid (SAHA), a histone deacetylase (HDAC) inhibitor, on the behavior of SUM159 breast cancer cells. Many HDAC inhibitors, including SAHA, have been a subject of controversy with highly conflicting results for the treatment of solid tumors in vitro as well as in clinical trials. We found that SAHA significantly inhibited cellular migration/proliferation, and decreased microtubule polarization. PMID- 29188844 TI - Poly(ferrocenylsilane) electrolytes as a gold nanoparticle foundry: "two-in-one" redox synthesis and electrosteric stabilization, and sensing applications. AB - Gold nanoparticles (AuNPs) coated with responsive polymers gained considerable interest due to their controllable size, good stability, and fast environmental response suitable for biological applications and sensing. Here we report on a simple and efficient method for the synthesis of stable and redox responsive AuNPs using organometallic polyelectrolytes in aqueous solutions of HAuCl4. In the redox reaction, positively or negatively charged poly(ferrocenylsilanes) (PFS+/PFS-) served as reducing agents, and also as stabilizing polymers. Due to their unique tunable electrostatic and electrosteric protection, AuNPs coated with PFS-, (PFS+)@AuNPs, possess high redox sensitivity, with reversible, repetitive, sustainable color switching between the assembled (purple color) and disassembled (red color) states as evidenced by UV-Vis absorption and TEM measurements. Feasibility studies reported here indicate that the particles described can be applied as a colorimetric probe for the detection of redox molecules, e.g. vitamin C, in a controlled and facile manner. PMID- 29188845 TI - Molecular targets and mechanisms of bioactive peptides against metabolic syndromes. AB - Bioactive peptides are present in all living organisms and have critical roles ranging from protection against infection as the key element of innate immunity, regulating blood pressure and glucose levels, to reducing signs of ageing by killing senescent cells. Bioactive peptides are also encrypted within food protein sequences that can be released during proteolysis or food processing. These specific food protein fragments are reported to have potential for improving human health and preventing metabolic diseases through their impact on inflammation, blood pressure, obesity, and type-2 diabetes. This review mainly focuses on the molecular targets and the underlying mechanisms of bioactive peptides against various metabolic syndromes including inflammation, high blood pressure, obesity, and type-2 diabetes, to provide new insights and perspectives on the potential of bioactive peptides for management of metabolic syndromes.

PMID- 29188848 TI - Bacterial self-defense antibiotics release from organic-inorganic hybrid multilayer films for long-term anti-adhesion and biofilm inhibition properties. AB - Implant-associated bacterial infections pose serious medical and financial issues due to the colonization and proliferation of pathogens on the surface of the implant. The as-prepared traditional antibacterial surfaces can neither resist bacterial adhesion nor inhibit the development of biofilm over the long term. Herein, novel (montmorillonite/poly-l-lysine-gentamicin sulfate)8 ((MMT/PLL-GS)8) organic-inorganic hybrid multilayer films were developed to combine enzymatic degradation PLL for on-demand self-defense antibiotics release. Small molecule GS was loaded into the multilayer films during self-assembly and the multilayer films showed pH-dependent and linear growth behavior. The chymotrypsin- (CMS) and bacterial infections-responsive film degradation led to the peeling of the films and GS release. Enzyme-responsive GS release exhibited CMS concentration dependence as measured by the size of the inhibition zone and SEM images. Notably, the obtained antibacterial films showed highly efficient bactericidal activity which killed more than 99.9% of S. aureus in 12 h. Even after 3 d of incubation in S. aureus, E. coli or S. epidermidis solutions, the multilayer films exhibited inhibition zones of more than 1.5 mm in size. Both in vitro and in vivo antibacterial tests indicated good cell compatibility, and anti inflammatory, and long-term bacterial anti-adhesion and biofilm inhibition properties. PMID- 29188849 TI - Surface properties of MoS2 probed by inverse gas chromatography and their impact on electrocatalytic properties. AB - Layered transition metal dichalcogenides (TMDs) are at the forefront of materials research. One of the most important applications of these materials is their electrocatalytic activity towards hydrogen evolution, and these materials are suggested to replace scarce platinum. Whilst there are significant efforts towards this goal, there are various reports of electrocatalysis of MoS2 (which is the most commonly tested TMD) with large variations of the reported electrocatalytic effect of the material, with overpotential varying by several hundreds of millivolts. Here, we analyzed surface properties of various bulk as well as single layer MoS2 samples using inverse gas chromatography. All samples displayed significant variations in surface energies and their heterogeneities. The surface energy ranged from 50 to 120 mJ m-2 depending on the sample and surface coverage. We correlated the surface properties and previously reported structural features of MoS2 with their electrochemical activities. We concluded that the observed differences in electrochemistry are caused by the surface properties. This is an important finding with an enormous impact on the whole field of electrocatalysis of layered materials. PMID- 29188850 TI - Fabrication of carbon quantum dots with nano-defined position and pattern in one step via sugar-electron-beam writing. AB - Quantum dots (QDs) are promising materials in nanophotonics, biological imaging, and even quantum computing. Precise positioning and patterning of QDs is a prerequisite for realizing their actual applications. Contrary to the traditional two discrete steps of fabricating and positioning QDs, herein, a novel sugar electron-beam writing (SEW) method is reported for producing QDs via electron beam lithography (EBL) that uses a carefully chosen synthetic resist, poly(2 (methacrylamido)glucopyranose) (PMAG). Carbon QDs (CQDs) could be fabricated in situ through electron beam exposure, and the nanoscale position and luminescence intensity of the produced CQDs could be precisely controlled without the assistance of any other fluorescent matter. We have demonstrated that upon combining an electron beam with a glycopolymer, in situ production of CQDs occurs at the electron beam spot center with nanoscale precision at any place and with any patterns, an advancement that we believe will stimulate innovations in future applications. PMID- 29188851 TI - Physiological responses and toxin production of Microcystis aeruginosa in short term exposure to solar UV radiation. AB - The aim of this study was to evaluate the effects of short-term (hours) exposure to solar UV radiation (UVR, 280-400 nm) on the physiology of Microcystis aeruginosa. Three solar radiation treatments were implemented: (i) PAR (PAR, 400 700 nm), (ii) TUVA (PAR + UVAR, 315-700 nm) and (iii) TUVR (PAR + UVAR + UVBR, 280-700 nm). Differential responses of antioxidant enzymes and the reactive oxygen species (ROS) production to UVR were observed. Antioxidant enzymes were more active at high UVR doses. However, different responses were observed depending on the exposure to UVAR or UVBR and the dose level. No effects were observed on the biomass, ROS production or increased activity of superoxide dismutase (SOD) and catalase (CAT) compared to the control when UVR + PAR doses were lower than 9875 kJ m-2. For intermediate doses, UVR + PAR doses between 9875 and 10 275 kJ m-2, oxidative stress increased while resistance was imparted through SOD and CAT in the cells exposed to UVAR. Despite the increased antioxidant activity, biomass decrease and photosynthesis inhibition were observed, but no effects were observed with added exposure to UVBR. At the highest doses (UVR + PAR higher than 10 275 kJ m-2), the solar UVR caused decreased photosynthesis and biomass with only activation of CAT by UVBR and SOD and CAT by UVAR. In addition, for such doses, a significant decrease of microcystins (MCs, measured as MC-LR equivalents) was observed as a consequence of UVAR. This study facilitates our understanding of the SOD and CAT protection according to UVAR and UVBR doses and cellular damage and reinforces the importance of UVR as an environmental stressor. In addition, our results support the hypothesized antioxidant function of MCs. PMID- 29188852 TI - Temperature-dependent IR-transition moment orientational analysis applied to thin supported films of poly-epsilon-caprolactone. AB - A novel experimental setup is described which enables one to carry out infrared transition moment orientational analysis (IR-TMOA) depending on temperature. By this, three dimensional molecular order parameter tensors of IR-active transition dipole moments with respect to the sample coordinate system can be determined in their thermal evolution (35 degrees C < T < 59 degrees C). As an example crystallinity and macroscopic order of poly-epsilon-caprolcatone are monitored. Both remain largely unaltered up to T ~ 50 degrees C, above which they decrease. These reductions are explained as the melting of flat-on crystalline lamellae that make up about 34% of the crystalline material. The remaining crystallites are arranged into bulk-like, confined spherulitic structures and do not melt by more than (3 +/- 3)%. Therefore, flat-on oriented lamellae are supposed to be kinetically favored by confinement during melt crystallization but are thermodynamically less stable than two-dimensionally confined bulk-like spherulites. PMID- 29188853 TI - Computerized Cognitive Testing for Use in Clinical Trials: A Comparison of the NIH Toolbox and Cogstate C3 Batteries. AB - BACKGROUND: As prevention trials for Alzheimer's disease move into asymptomatic populations, identifying older individuals who manifest the earliest cognitive signs of Alzheimer's disease is critical. Computerized cognitive testing has the potential to replace current gold standard paper and pencil measures and may be a more efficient means of assessing cognition. However, more empirical evidence about the comparability of novel computerized batteries to paper and pencil measures is required. OBJECTIVES: To determine whether two computerized IPad batteries, the NIH Toolbox Cognition Battery and Cogstate-C3, similarly predict subtle cognitive impairment identified using the Preclinical Alzheimer Cognitive Composite (PACC). DESIGN, SETTING, PARTICIPANTS: A pilot sample of 50 clinically normal older adults (Mage=68.5 years+/-7.6, 45% non-Caucasian) completed the PACC assessment, and the NIH Toolbox and Cogstate-C3 at research centers of Massachusetts General and Brigham and Women's Hospitals. Participants made 3-4 in clinic visits, receiving the PACC first, then the NIH Toolbox, and finally the Cogstate-C3.>= 0.5SD), versus subtle cognitive impairment (<0.5SD). Composites for each computerized battery were created using principle components analysis, and compared with the PACC using non-parametric Spearman correlations. Logistic regression analyses were used to determine which composite was best able to classify subtle cognitive impairment from typical performance. RESULTS: The NIH Toolbox formed one composite and exhibited the strongest within-battery alignment, while the Cogstate-C3 formed two distinct composites (Learning-Memory and Processing Speed-Attention). The NIH Toolbox and C3 Learning-Memory composites exhibited positive correlations with the PACC (rho=0.49, p<0.001; rho=0.58, p<0.001, respectively), but not the C3 Processing Speed-Attention composite, rho=-0.18, p=0.22. The C3 Learning-Memory was the only composite that classified subtle cognitive impairment, and demonstrated the greatest sensitivity (62%) and specificity (81%) for that subtle cognitive impairment. CONCLUSIONS: Preliminary findings suggest that the NIH Toolbox has the advantage of showing the strongest overall clustering and alignment with standardized paper-and-pencil tasks. By contrast, Learning-Memory tasks within the Cogstate-C3 battery have the greatest potential to identify cross-sectional, subtle cognitive impairment as defined by the PACC. PMID- 29188854 TI - Short-Term Impact of a Combined Nutraceutical on Cognitive Function, Perceived Stress and Depression in Young Elderly with Cognitive Impairment: A Pilot, Double Blind, Randomized Clinical Trial. AB - BACKGROUND: The prevalence of senile dementia is increasing worldwide, especially in the developed countries. Nevertheless, drug therapy isn't often enough to treat this condition. Researchers are evaluating the possible impact of a preventive approach, based on an improvement of lifestyle and the intake of micronutrients. Moreover, there is an increasing interest for combined nutraceuticals that can act as memory and learning enhancers, with a significant and beneficial potential on the cognitive disorders. OBJECTIVE: To evaluate the effects of a rational assemblage of nutraceuticals on cognitive functions in a sample of 30 elderly subjects. DESIGN: Double bind, cross-over designed trial versus placebo Setting: outpatient clinical practice. PARTICIPANTS: 30 elderly subjects with basal Mini-Mental State Examination score between 20 and 27 and self-perceived cognitive decline. INTERVENTION: Treatment with a combination of nutraceuticals based on Bacopa monnieri, L-theanine, Crocus sativus, copper, folate and vitamins of B and D group. After2 months of treatment or placebo. MEASUREMENTS: Patients were evaluated with Mini-Mental State Examination (MMSE), Perceived Stress Questionnaire (PSQ) and Index and Self-Rating Depression Scale (SRDS). RESULTS: MMSE and PSQ Index significantly improved in the active treatment arm, both versus baseline and versus the parallel arm. Both groups experienced a significant improving in the SRDS scores. CONCLUSIONS: We obtained a good and significant improvement of the cognitive functions tested with the MMSE, PSQ-Index and SRDS score, after 2 months of combined therapy of nutraceuticals. Further confirmation will be needed to verify these observations on the middle and long term in a larger number of subjects. PMID- 29188855 TI - Ginkgo Biloba Extract Consumption and Long-Term Occurrence of Death and Dementia. AB - OBJECTIVES: To study the benefit of Ginkgo Biloba Extract (GBe) consumption on the long term risk of dementia and death in elderly people. DESIGN: The Paquid study is a population-based cohort with regular follow-up screenings up to twenty two years and systematic detection of incident cases of dementia. Statistical analysis was conducted with an illness-death model dealing with interval censoring of dementia and competing risk of death. SETTING: The sample was randomly selected from electoral rolls in two administrative areas of southwestern France in 1988-1989. PARTICIPANTS: 3,777 subjects aged 65 years or older at baseline who were living at home. MEASUREMENT: Participants were visited at home by a trained psychologist at baseline in 1988/1989, and then again approximately every two years. Drug consumption for the treatment of cognitive or neurosensory impairment was collected at baseline. Participants were classified as GBe consumers, other drug (OD) consumers and untreated controls (UC) for this motive. RESULTS: After adjustment for sociodemographic factors and cognitive measures at baseline the risk for dementia was not significantly different in GBe consumers and UC (Hazard Ratio (HR)=1.21, 95% Confidence Interval (95% CI)=0.95 1.55, p=0.42) and it was of the same magnitude but significantly increased in the OD group versus UC (HR=1.25, 95% CI=1.06-1.46, p=0.004). With the same adjustment, the risk of dying in non-demented subjects was reduced in GBe consumers versus UC (HR=0.67, 95% CI=0.49-0.93, p=0.02) while it was the same as the reference group in OD consumers. The mean lifetimes without dementia was of 11.2 years in the UC group (95% CI=10.9-11.5), 11.1 years in the GBe group (10.2 11.9) and 9.1 years for the OD group (8.7-9.6). CONCLUSION: GBe consumers have a lower risk of dying before dementia and a longer lifetime without dementia than participants taking other drugs for the same indication. PMID- 29188856 TI - Stimulus-Locked Lateralized Readiness Potential and Performance: Useful Markers for Differentiating between Amnestic Subtypes of Mild Cognitive Impairment. AB - BACKGROUND: The findings of previous studies, in which event-related potentials (ERPs) related to stimulus evaluation were measured, do not fully explain the behavioral decline observed in amnestic mild cognitive impairment (aMCI; prodromal stage of Alzheimer's Disease). OBJECTIVES: Motor ERPs were evaluated in this study with the aim of discovering complementary explanations and identifying aMCI biomarkers. DESIGN: Cross-sectional study. SETTING: Santiago de Compostela, Galicia, Spain. PARTICIPANTS: Nineteen healthy control (52-81 years old), 21 single-domain aMCI (sdaMCI; 51-87 years old) and 12 multi-domain aMCI (mdaMCI, 62 85 years old) adults. MEASUREMENTS: Reaction times (RTs), percentage of hits, and stimulus-locked and response-locked lateralized readiness potentials (sLRP and rLRP, indexes of response selection and preparation) were evaluated. RESULTS: mdaMCI participants showed longer RTs than control adults and less hits than control and sdaMCI participants. In addition, the mdaMCI group showed lower sLRP amplitudes than the control participants, and the sdaMCI group showed longer sLRP peak latencies. CONCLUSIONS: Control and sdaMCI groups did not differ in relation to RTs or hits, although sLRP peak latencies (sensitivity and specificity >.73) were longer in the sdaMCI group, which may be a sign of compensatory mechanisms or early indication of a decline in motor control. RTs were longer and sLRP amplitudes were smaller in the mdaMCI than in the Control group, and mdaMCI scored fewer hits than control and sdaMCI participants, indicating behavioral and neurocognitive deficits. The combination of hits and RTs discriminated mdaMCI from control adults (sensitivity and specificity >.82); and the combination of sLRP peak latency and hits discriminated mdaMCI from sdaMCI adults (sensitivity=1.00, specificity=.88). PMID- 29188857 TI - Assessing the Relationship between Vitamin D Status and Impairments in Cognitive and Physical Performance in Older Adults Using a Dual Task Physical Performance Test. AB - BACKGROUND: Vitamin D deficiency has been associated with an increased risk of falls in older adults. Several studies have demonstrated an association between vitamin D deficiency and gait and cognitive impairments, which are two risk factors for falls in the elderly. There is lack of research about the role of vitamin D in cognitive function in the context of mobility. OBJECTIVE: The purpose of this study was to evaluate the association between vitamin D status with the age-related changes in mobility through higher order cognitive function using a dual task physical performance test. DESIGN: Cross-sectional. SETTING: Community-dwelling older adult population located in Miami, Fl. PARTICIPANTS: Healthy participants over the age of 55 (n=97) who participated in the parent interventional study. MEASUREMENTS: Participants completed assessments that included serum levels of vitamin D, surveys, and dual task physical performance tests. Spearman's correlations, independent t-tests, repeated measures ANOVAs and multiple logistic regressions were used to examine the relationship between vitamin D insufficiency (25-hydroxyvitamin D <30 ng/ml) and sufficiency (>=30 ng/ml) and dual task physical performance variables. The significance level was set at alpha=0.05. RESULTS: There were no significant associations between vitamin D insufficiency and gait velocity during either task. Using Spearman correlations, slower single (P=0.011) and dual task counting rates (P=0.006) were significantly associated with vitamin D insufficiency. Independent t-tests showed dual and single task counting rates were significantly lower in the vitamin D insufficient group compared to the sufficient group (P=0.018 and P=0.028, respectively). The results for the ANOVAs indicated that velocities and counting rates were not significantly different by vitamin D status (Wilk's Lambda =0.999; F (1, 95) =.11, P=.740) (Wilk's Lambda =.999, F(1,95)=.13, P=.718). Vitamin D status was not significantly associated with dual task physical performance (defined as the difference in dual and single task) in gait velocity (OR=1.00, 95% CI: 0.98; 1.02, P=0.772) and counting rate (OR=1.684, 95% CI: 0.15; 19.57, P=0.677), when controlling for confounders. CONCLUSIONS: Since counting backward is a mental tracking task, which is a component of executive function, our results suggest a relationship between vitamin D insufficiency and executive dysfunction. Executive dysfunction has been previously associated with fall risks in the elderly, and it could be a possible mediator between vitamin D and falls. Our data suggest that cognition may play a significant role in vitamin D's influence on falls, while motor function may play a lesser role. PMID- 29188858 TI - Modest Overweight and Healthy Dietary Habits Reduce Risk of Dementia: A Nationwide Survey in Taiwan. AB - BACKGROUND: Evidence of the associations of dietary habits and body mass index with dementia is inconsistent and limited in East Asian countries. OBJECTIVE: We aim to explore the associations of dietary habits and body mass index with the odds of dementia. DESIGN: Cross-sectional observational study. SETTING: A nationwide, population-based, door-to-door, in-person survey. PARTICIPANTS: Selected by computerized random sampling from all 19 counties in Taiwan. MEASUREMENT: Diagnosis of dementia using the criteria recommended by the National Institute on Aging-Alzheimer's Association. Lifestyle factors, dietary habits and demographic data were compared between normal subjects and participants with dementia. RESULTS: A total of 10432 residents were assessed, among whom 2049 were classified as having a mild cognitive impairment (MCI), 929 were diagnosed with dementia, and 7035 were without dementia or MCI. After adjustment for age, gender, education, body mass index (BMI), dietary habits, habitual exercises and co-morbidities, including hypertension, diabetes and cerebrovascular diseases, we found inverse associations of dementia with the consumption of fish (OR 0.62, 95% CI 0.41-0.94), vegetables (OR 0.35, 95% CI 0.13-0.95), coffee (OR 0.59, 95% CI 0.35-0.97), green tea (OR 0.51, 95% CI 0.34-0.75) and other types of tea (OR 0.41, 95% CI 0.28-0.60). There was no association between dementia and fruit consumption. Compared with people who had a normal BMI (18 < BMI <= 24), older overweight people (24 < BMI <=30) had a reduced risk of dementia with an adjusted OR of 0.77 (95% CI 0.61-0.96). CONCLUSIONS: Our study provides preliminary evidence that suggests that the consumption of fish, vegetables, tea, and coffee has potential benefits against dementia in East Asian population. Being modestly overweight (nadir risk at BMI = 25) in late life was associated with decreased odds of dementia. The benefit of fruits may be offset by their high sugar content. PMID- 29188860 TI - A Keto-Mediet Approach with Coconut Substitution and Exercise May Delay the Onset of Alzheimer's Disease among Middle-Aged. AB - BACKGROUND: Coconut oil has been widely used to improve health because there is much information available by word of mouth, in books, and on the internet. However, researchers still continue to search for the best diets to improve the quality of life, especially for people with cognitive decline. OBJECTIVES: The aim of this review is to develop a novel dietary approach, the Keto-Mediet, which may help prevent the onset of Alzheimer's disease. METHODS: Evidence gained through literature review from 1982 to 2015 on gene-by-diet interaction and lipid and glucose metabolism in the brains of Alzheimer's patients is converted into the new Keto-Mediet approach. DESIGN: The Keto-Mediet approach combines the benefits of a Ketogenic diet and a Mediterranean diet into a pyramidal model that is rich in various types of vitamins and substitutes coconuts for saturated animal fats. Limited glucose intake is intended to delay brain degeneration. A revised adult food pyramid was created to illustrate the principles of the Keto Mediet approach. CONCLUSION: The Keto-Mediet approach represents and interprets food groups according to the revised adult food pyramid. This approach also encourages adherence to this healthy diet and lifestyle changes including exercise for people whose age ranges from 40 to 75 years. Those who comply with this approach will significantly enhance their knowledge and adopt a healthier lifestyle, as compared to those whose modern eating patterns are typically less healthy. Therefore, the Keto-Mediet approach can be applied in hopes of preventing and decreasing Alzheimer's disease in different ethnicities and cultural groups. PMID- 29188859 TI - Cognitive Performance Does not Limit Physical Activity Participation in the Lifestyle Interventions and Independence for Elders Pilot Study (LIFE-P). AB - OBJECTIVES: We examined whether multiple domains of baseline cognitive performance were associated with prospective physical activity (PA) adherence in the Lifestyle Interventions and Independence for Elders Pilot study (LIFE-P). DESIGN, SETTING, PARTICIPANTS: The LIFE-P study was a single-blind, multicenter, randomized controlled trial of a PA intervention compared to a successful aging educational intervention in sedentary, mobility-limited older adults. INTERVENTION: A 12-month structured, moderate-intensity, multi-modal PA program that included walking, resistance training, and flexibility exercises. For the first 2 months (adoption), 3 center-based exercise sessions (40-60 min) / week were conducted. During the next 4 months (transition), center-based sessions were conducted 2 times / week. The subsequent maintenance phase consisted of optional once-to-twice-per-week center-based sessions and home-based PA. MEASUREMENTS: Tests of executive and global cognitive functioning, working memory and psychomotor speed were administered at baseline. Median test scores were used to dichotomize participants into low or high cognitive performance groups. RESULTS: 52 mobility-limited older adults (age: 76.9 +/-5 yrs) were randomized to the PA arm of LIFE-P. Compared to participants with high cognitive performance, participants with low performance had similar PA adherence rates (all P >= 0.34). Furthermore, weak and non-significant univariate relationships were elicited between all measures of cognition and overall PA adherence levels (r values ranged: -0.20 to 0.12, P >= 0.12). CONCLUSION: These data suggest that cognitive performance does not limit long-term PA adherence in mobility-limited older adults. Additional studies in larger cohorts are warranted to verify these findings. PMID- 29188861 TI - Antioxidants in the Diet and Cognitive Function: Which Role for the Mediterranean Life-style? AB - This review aims to focus on main antioxidants- abundantly contained in the diet- as well as of the whole Mediterranean diet and life-style and their relationship with cognitive function, especially critical in two phases of life, in children until adolescence and oldness. The role of emerging biochemical and molecular biomarkers as opportunity to estimate more accurately nutritional assumption and requirement, in terms of cognitive preservation and disease risk, will be also discussed. The cluster of factors within the Mediterranean pattern -which include not only nutritional, but also physical, social, and stimulating aspects- is still largely understudied as a whole, but it is proposed as attractive research area and tool for public health planning of prevention and intervention.

PMID- 29188863 TI - Cross-Sectional Associations of Total Plasma Homocysteine with Cortical beta Amyloid Independently and as a Function of Omega 3 Polyunsaturated Fatty Acid Status in Older Adults at Risk of Dementia. AB - OBJECTIVES: Elevated total plasma homocysteine is a risk factor for Alzheimer's disease (AD) and there is some evidence that omega-3 polyunsaturated fatty acids (n-3 PUFAs) can modulate the effects of homocysteine-lowering B vitamins on AD related pathologies. Hence we investigated the relationship between total plasma homocysteine and cortical beta-amyloid (Abeta) in older adults at risk of dementia. The role of erythrocyte membrane n-3 PUFAs (omega 3 index) on this relationship was also explored. DESIGN: This is a cross-sectional study using data from the Multidomain Alzheimer Preventive Trial (MAPT); a randomised controlled trial. SETTING: French community dwellers aged 70 or over reporting subjective memory complaints, but free from a diagnosis of clinical dementia. PARTICIPANTS: Individuals were from the MAPT trial (n = 177) with data on total plasma homocysteine at baseline and cortical Abeta load. MEASUREMENTS: Cortical to-cerebellar standard uptake value ratios were assessed using [18F] florbetapir positron emission tomography (PET). Total baseline plasma homocysteine was measured using an enzymatic cycling assay. Baseline omega 3 index was measured using gas chromatography. Cross-sectional associations were explored using adjusted multiple linear regression models. RESULTS: We found that total baseline plasma homocysteine was not significantly associated with cortical Abeta as demonstrated using multiple linear regression models adjusted for age, sex, education, cognitive status, time interval between baseline and PET-scan, omega-3 index, MAPT group allocation and Apolipoprotein E epsilon4 status (B-coefficient 0.001, 95 % CI: -0.008,0.006, p = 0.838). Exploratory analysis showed that homocysteine was however significantly associated with cortical Abeta in subjects with low baseline omega-3 index (< 4.72 %) after adjustment for Apolipoprotein E epsilon4 status (B-coefficient 0.041, 95 % CI: 0.017,0.066, p = 0.005, n = 10), but not in subjects with a high baseline omega-3 index (B-coefficient -0.010, 95 % CI: -0.023,0.003, p = 0.132, n = 66). CONCLUSIONS: The role of n-3 PUFAs on the relationship between homocysteine and cerebral Abeta warrants further investigation. PMID- 29188864 TI - Development of a Novel Six-Month Nutrition Intervention for a Randomized Trial in Older Men with Mobility Limitations. AB - OBJECTIVES: Nutrition impacts the development of sarcopenia and protein intake is an important modulator of skeletal muscle mass loss in older people. The Optimizing Protein Intake in Older Men with Mobility Limitation (OPTIMEN) Trial was designed to assess the independent and combined effects of higher protein intake and a promyogenic agent, testosterone, on lean body mass, muscle strength and physical function in older men with mobility disability. The purpose of this paper is to describe the experimental design and nutrition intervention, including techniques used by research dietitians to develop and deliver energy and protein-specific meals to the homes of community-dwelling participants. Strategies to enhance long-term dietary compliance are detailed. DESIGN: Randomized, double-blind, placebo-controlled six-month intervention trial. SETTING: Participants were recruited from Boston MA USA and surrounding communities. PARTICIPANTS: Older men who were mobility-limited (Short Physical Performance Battery (SPPB) 3-10) and consuming less protein (<0.83 g/kg/day) were recruited for this study. INTERVENTION: Here we report the successful implementation of a double-blind, placebo-controlled, parallel group, randomized controlled trial with a 6-month intervention period among community-living men, age 65 years and older with a mobility limitation. A controlled feeding plan was used to deliver required energy intakes and prescribed protein quantities of 0.8 or 1.3 grams/kilogram/day (g/kg/d) in three meals plus snacks and supplements. A 2x2 factorial design was used to assess the effects of protein level alone and in combination with testosterone (vs. placebo) on changes in lean body mass (primary outcome), muscle strength, and physical function. RESULTS: A total of 154 men met the eligibility criteria; 112 completed a 2-week run-in period designed to evaluate compliance with the nutrition intervention. Of these, 92 subjects met compliance eligibility criteria and agreed to be randomized; 85% completed the full trial. The study successfully delivered three meals per day to subjects, with a high degree of compliance and subject satisfaction. Overall self-reported compliance rates were 80% and 93% for the meals and supplements, respectively. Details of compliance strategies are discussed. CONCLUSION: This community-based study design may serve as a model for longer-term nutritional interventions requiring monitoring of dietary compliance in a home-based feeding and supplementation trial. PMID- 29188865 TI - Dietary Diversity and Cognitive Function among Elderly People: A Population-Based Study. AB - OBJECTIVES: To explore associations of dietary diversity with cognitive function among Chinese elderly. DESIGN: This cross-sectional study was conducted in 2011 2012, data were analyzed using multiple linear regression and logistic regression models. SETTING: community-based setting in the 23 provinces in China. SUBJECTS: 8,571 elderly participants, including 2984 younger elderly aged 65-79 and 5587 oldest old aged 80+ participated in this study. MEASUREMENT: Intake frequencies of food groups was collected and dietary diversity (DD) was assessed based on the mean of DD score. Cognitive function was assessed using the Chinese version of Mini-Mental State Examination (MMSE), and cognitive impairment was defined using education-based cutoffs. Information about socio-demographics, lifestyles, resilience and health status was also collected. RESULTS: Poor dietary diversity was significantly associated with cognitive function, with beta (95% CI) of 0.11(-0.14, -0.08) for -log (31-MMSE score) and odds ratio (95% CI) of 1.29 (1.14, 1.47) for cognitive impairment. Interaction effect of age with DD was observed on cognitive impairment (P interaction=0.018), but not on -log (31-MMSE score) (P interaction=0.08). Further separate analysis showed that poor DD was significantly associated with increased risk of cognitive impairment in the oldest old (p<0.01), with odds ratio (95% CI) of 1.34 (1.17, 1.54), while not in the younger elderly (p>0.05), with OR (95% CI) being 1.09 (0.80, 1.47) in the fully adjusted model. Similar results were obtained when DD was categorized into four groups. CONCLUSIONS: Poor dietary diversity was associated with worse global cognitive function among Chinese elderly, and particularly for the oldest old. This finding would be very meaningful for prevention of cognitive impairment. PMID- 29188866 TI - Alcohol Energy Intake Is Related to Low Body Mass Index in Japanese Older Adults: Data from the 2010-2011 National Health and Nutrition Survey. AB - OBJECTIVE: The objective of this study was to identify lifestyle and nutritional factors associated with low BMI in Japanese older adults, with a focus on alcohol energy intake. DESIGN: Cross-sectional study. PARTICIPANTS: Data from 1,093 respondents (711 men and 382 women) to the National Health and Nutrition Survey aged 65 years and older were included in this study. MEASUREMENTS: Data were analyzed for associations between BMI and lifestyle, energy, and nutrient intake. Alcohol energy intake was calculated from total energy and participants were categorized into BMI quartiles. Energy-adjusted nutrient intakes were calculated as residuals from a regression model, with BMI as the independent variable and lifestyle factors and nutrient intake as dependent variables. Between-BMI quartile differences were assessed for each sex using multivariate logistic regression analysis. In addition, the nutrient intakes of men consuming more than 280 kcal and less than 280 kcal of alcohol energy per day were compared. RESULTS: Men and women in the lowest BMI quartile had lower total energy intake but higher alcohol energy intake than men in the other BMI quartiles. In multivariate logistic regression analysis, the lowest BMI quartile was associated with total energy (OR: 0.81, p = 0.0310) and alcohol energy intake (OR: 1.22, p = 0.0472) in men. In men, protein, carbohydrate, fat, calcium, iron, and vitamin intakes were less in those that consumed >= 280 kcal than in those that consumed < 280 kcal of alcohol per day. CONCLUSION: Our results demonstrate an association between alcohol energy intake and low BMI in older Japanese individuals. PMID- 29188867 TI - High Free Fatty Acid Levels Are Associated with Stroke Recurrence and Poor Functional Outcome in Chinese Patients with Ischemic Stroke. AB - BACKGROUND: The aim of this study is to investigate whether serum and cerebrospinal fluid (CSF) free fatty acid (FFA) levels are associated with outcome and recurrence in a cohort of patients with an acute ischemic stroke (AIS). METHODS: From December 2013 to May 2015, patients with first-ever AIS were included. FFA level and NIH stroke scale (NIHSS) were measured at the time of admission. Logistic regression analysis was used to evaluate the stroke outcome and recurrence according to FFA level. Clinical follow-up was performed at 6 month. RESULTS: In our study, we studied 296 patients (52.7% male). We have found a positive correlation between serum and CSF levels of FFA. Patients with a poor outcome and recurrence had significantly increased FFA serum and CSF levels on admission (all p<0.0001). Multivariate logistic regression analysis adjusted for common risk factors showed that FFA was an independent predictor of poor functional outcome and recurrence. Odds ratios (OR) values were more significant for the higher levels of FFA. CONCLUSION: In summary, baseline serum and CSF FFA level were associated with stroke poor function outcome and recurrence, suggesting an effect of FFA on disease course in AIS. PMID- 29188868 TI - Vitamin D Deficiency and Insufficiency Prevalence in the West of Ireland - A Retrospective Study. AB - OBJECTIVES: Vitamin D plays an important role in calcium homeostasis and is essential for normal bone growth and remodeling. Previous studies of acutely ill and institutionalized older women in Galway revealed that vitamin D insufficiency is extremely common. We aimed to evaluate age and gender-related rates of vitamin D insufficiency and deficiency in adult patients attending their General Practitioners in the same region. DESIGN: A retrospective cohort study. SETTING: General practices in Galway, a city located on the west coast of Ireland, latitude 53.17 North. PARTICIPANTS: A total of 15,708 consecutive blood samples from adults attending their General Practitioners between January 2013 and December 2014 were sent to the Clinical Biochemistry Laboratory in the University Hospital Galway for vitamin D level testing. 73% were from women. INTERVENTION: Data were collected and grouped according to age, sex and season. Vitamin D levels (25OHD) were categorised into deficiency (<25nmol/L), insufficiency (25 50nmol/L) and sufficiency ( >50nmol/L). MEASUREMENTS: Median and interquartile range were reported as vitamin D levels were not normally distributed. Descriptive statistics were performed using STATA/MP 13.1 for Mac. RESULTS: While vitamin D levels were sufficient in 56.4% (n=8,496), they were insufficient in 32.4% (n=4,891) and deficient in 11.2% (n=1,691). Of the deficient group, 19%( 325) had levels <15nmol/L consistent with profound deficiency. Men were more likely than women to be deficient (12% (n=489) vs. 10.9% (n=1,202)) and insufficient (38.0% (n=1,550) vs. 30.4% (n=3,341)) (p<0.01). Highest rates of deficiency were seen in those 81-97 years (19.4% (n=136)) and 18-40 years (13.8% (n=543)), the former group showing less seasonal variation. CONCLUSION: Overall prevalence of insufficiency is similar to those in national and European studies published recently. However, there is a high possibility that those most vulnerable to vitamin D deficiency were underrepresented in this cohort, when results from previous studies in the same region are considered. Further prospective studies are needed to guide treatment with supplementation of vitamin D for appropriate subgroups. PMID- 29188869 TI - Changes in Lean Mass and Serum Myostatin with Habitual Protein Intake and High Velocity Resistance Training. AB - OBJECTIVES: Examine the associations between dietary protein intake, lean mass (LM), and serum myostatin (Mstn) levels among community-dwelling older adults participating in a 20-week high-velocity resistance training (HVRT) program. DESIGN, SETTING, AND PARTICIPANTS: This longitudinal study consisted of 33 community-dwelling, older adults (mean age 77.0 years, SD = 6.4); all of which obtained physician clearance prior to study participation. MEASUREMENTS: Twenty five females and eight males were randomized to a control (CON) or HVRT group. Anthropometric measures were obtained via dual energy x-ray absorptiometry (DXA) and peripheral venous blood draw used for serum myostatin analysis. Exercise was performed twice per week for 20 consecutive weeks. Food intake estimation with a diet history questionnaire (DHQ) was used for protein intake comparison to the recommended dietary allowance (RDA). All measures were recorded both prior to and following study participation. RESULTS: Altogether, protein was consumed in amounts more generous (1.01 +/- 0.47 g.kg-1.d-1) than that of the RDA (0.8 g.kg 1.d-1). As a result of significant LM differences among men and women (p < 0.01), additional data were analyzed specific to sex. Serum myostatin was greater among females (6681.8 +/- 3155.0 pg.mL-1) than males (5560.0 +/- 2946.1 pg.mL-1); however, these values were not significantly different (p = 0.39). Combined, protein consumption and serum myostatin did not significantly influence LM among males (p = 0.09) or females (p = 0.71). Irrespective of training group, significant changes were not exhibited in dietary intake patterns, LM, or serum myostatin. CONCLUSIONS: Contrary to the proposed hypothesis, results suggest protein consumption and circulating serum myostatin levels did not significantly influence LM among older adults. Although HVRT positively impacts LM, neither exercise group displayed significant changes in LM. Therefore, further research is needed examining dietary intake, exercise modality, and myostatin downregulation as non-pharmacological approaches to combating sarcopenia. PMID- 29188870 TI - Association between Siesta (Daytime Sleep), Dietary Patterns and the Presence of Metabolic Syndrome in Elderly Living in Mediterranean Area (Medis Study): The Moderating Effect of Gender. AB - OBJECTIVES: Several lifestyle parameters including diet, physical activity and sleep were associated in isolation with the presence of Metabolic Syndrome (MetS) in adults, to date there is a paucity of studies which evaluated their combined role aging populations and especially with respect to gender. Therefore, the aim of the present study was to provide a global consideration of the lifestyle factors associated with MetS among elderly individuals. DESIGN: Cross-sectional observational study. SETTING: 21 Mediterranean islands and the rural Mani region (Peloponnesus) of Greece. PARTICIPANTS: during 2005-2015, 2749 older (aged 65-100 years) from were voluntarily enrolled in the study. MEASUREMENTS: Dietary habits, energy intake, physical activity status, socio-demographic characteristics, lifestyle parameters (sleeping and smoking habits) and clinical profile aspects were derived through standard procedures. The presence of MetS was defined using the definition provided by NCEP ATP III (revised) and cluster analysis was used to identify overall dietary habit patterns. RESULTS: The overall prevalence of MetS in the study sample was 36.2%, but occurred more frequently in females (40.0% vs. 31.8%, respectively, p=0.03). Individuals with MetS were more likely to sleep during the day (89.4% vs. 76.8% respectively, p=0.039) and frequent 'siesta' was positively linked to the odds of MetS presence in females (Odds Ratio (OR) =3.43, 95% Confidence Intervals (CI): 1.08-10.9), but not for men (p=0.999). The lower carbohydrate (i.e., 45.2% of total daily energy, 120+/ 16gr/day) dietary cluster was inversely associated with the odds for MetS presence, but only for men (OR=0.094, 95%CI: 0.010-0.883). CONCLUSIONS: Lifestyle parameters including sleep and diet quality are strongly associated with the presence of MetS in elderly cohort, but different their level of influence appears to be different, depending on gender. Further research is needed to better consider the role of lifestyle characteristics in the management of MetS in clinical practice. PMID- 29188871 TI - Impact of Age on the Association Between Body Mass Index and All-Cause Mortality in Patients with Atrial Fibrillation. AB - OBJECTIVES: To explore the impact of age on the association between body mass index (BMI) and all-cause mortality in patients with atrial fibrillation (AF). METHODS: A total of 1991 patients with AF (69 +/- 13 years, 54.9% female) were divided into three age groups: < 65 years, 65-75 years, and > 75 years, and followed for one year. The primary outcome was defined as all-cause mortality, with secondary outcomes including thromboembolism and major bleeding. Cox regression models were utilized to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: Compared to patients aged < 65 years, elder groups had much lower BMI and more comorbidities other than a lower prevalence of valvular heart disease. During one-year follow-up, 277 (13.9%) patients died, 158 (7.9%) underwent thromboembolism events and 26 (1.3%) had major bleeding. Mortality and thromboembolism risk were both notably higher in patients with advanced age (all P values < 0.001). Using normal weight patients as reference, mortality risk was significantly lower in overweight (HR 0.548; 95% CI 0.404 0.744) and obese patients (HR 0.536; 95% CI 0.325-0.883) for the entire cohort, with reduced death risk mainly observed in overweight patients aged 65-75 years (HR 0.285; 95% CI 0.131-0.621) and aged > 75 years (HR 0.686; 95% CI 0.473 0.993), but not in patients aged < 65 years. Continuous analyses of BMI indicated consistent results. CONCLUSION: High BMI is associated with reduced mortality rate in patients with AF, and this association is affected by age, with the so called "obesity paradox" confined to those with advanced age rather than young patients. PMID- 29188872 TI - Soluble Milk Proteins Improve Muscle Mass Recovery after Immobilization-Induced Muscle Atrophy in Old Rats but Do not Improve Muscle Functional Property Restoration. AB - OBJECTIVES: Effect of 3 different dairy protein sources on the recovery of muscle function after limb immobilization in old rats. DESIGN: Longitudinal animal study. SETTING: Institut National de la Recherche Agronomique (INRA). The study took part in a laboratory setting. INTERVENTION: Old rats were subjected to unilateral hindlimb immobilization for 8 days and then allowed to recover with 3 different dietary proteins: casein, soluble milk proteins or whey proteins for 49 days. MEASUREMENTS: Body weight, muscle mass, muscle fibre size, isometric, isokinetic torque, muscle fatigability and muscle oxidative status were measured before and at the end of the immobilization period and during the recovery period i.e 7, 21, 35 and 49 days post immobilization. RESULTS: In contrast to the casein diet, soluble milk proteins and whey proteins were efficient to favor muscle mass recovery after cast immobilization during aging. By contrast, none of the 3 diary proteins was able to improve muscle strength, power and fatigability showing a discrepancy between the recovery of muscle mass and function. However, the soluble milk proteins allowed a better oxidative capacity in skeletal muscle during the rehabilitation period. CONCLUSION: Whey proteins and soluble milk proteins improve muscle mass recovery after immobilization-induced muscle atrophy in old rats but do not allow muscle functional property restoration. PMID- 29188873 TI - p49/STRAP, a Serum Response Factor Binding Protein (SRFBP1), Is Involved in the Redistribution of Cytoskeletal F-Actin Proteins during Glucose Deprivation. AB - The functional decline that usually accompanies adult aging also encompasses cellular changes including cytoplasmic architecture. In addition to their role in cytoskeletal structure, actin microfilaments have important roles in various cellular processes, including cell-to-cell communication and intracellular signaling. Age-related diseases and late-stage cellular morphological appearances often correlate with altered f-actin structure, which has been observed most notably in cancer. What remains less clear are the molecular pathways that may be involved in normal and premature aging-induced f-actin changes. We report herein that p49/STRAP, a serum response factor binding protein (SRFBP1), is increased with normal aging and appears to be sensitive to low glucose-exposure. Our study results suggest that increased levels of p49/STRAP expression tend to correlate with f-actin redistribution genes, particularly cofilin, while siRNA-mediated knockdown of p49/STRAP resulted in a reduction of thymosin-beta4. Furthermore, with the redistribution of f-actin, we observed an increase in the intermediate filament vimentin, compatible with the notion that vimentin may be increased due to its greater role in cytoskeletal dynamics during advancing population doubling levels (PDLs) and in response to a low-glucose exposure. Taken together, these data suggest that p49/STRAP may play a role in glucose-deprivation associated cytoskeletal changes. PMID- 29188874 TI - Blood Pressure Is Associated with Tea Consumption: A Cross-sectional Study in a Rural, Elderly Population of Jiangsu China. AB - OBJECTIVES: Tea has long been hypothesized to possess hypotensive effects. However, there is uncertainty regarding the association of tea consumption with arterial blood pressure (BP). We aimed to examine the association between tea consumption and BP components including systolic BP (SBP) and diastolic BP (DBP). DESIGN: Community-based, cross-sectional study of Suzhou City, Jiangsu Province, China. SETTING: Tea consumption has protective influence on BP and presence of hypertension. PARTICIPANTS: 4579 older adults aged 60 years or older from the Weitang Geriatric Diseases study. MEASUREMENTS: Detailed information regarding tea consumption was collected using a pre-designed questionnaire. BP components were measured at least 3 times with a minimum 5-minute interval, by well-trained research nurses. METHODS: Data of 4579 older adults (response rate: 82%) aged 60 years or older from the Weitang Geriatric Diseases study were included in the analysis and we estimated the relationship of tea consumption and BP using linear regression models and the association between tea consumption and risk of hypertension using logistic regression models. RESULTS: In linear regression models, higher tea consumption frequency was found to be associated with lower systolic BP values, after adjusting for the effect of age, sex, education level, lifestyle-related factors, and cardiometabolic confounding factors in overall (coefficient =-1.49, P=0.0003), normotensive (coefficient =-0.91, P=0.017) and participants without anti-hypertensive treatment (coefficient =-1.26, P=0.027). Significant inverse association between diastolic BP and frequency of tea consumption was also observed in the overall subjects (coefficient =-0.74, P=0.003). In multivariate logistic analyses, habitual tea drinking was inversely associated with presence of hypertension [odds ratio (OR)=0.79, P=0.011] , and there was a progressive reduction in risk associated with higher frequency of tea consumption (P for trend=0.011). CONCLUSION: Habitual tea consumption was found to be associated with lower values of components of BP and a reduced likelihood of having hypertension in older adults. Given the widespread consumption of tea throughout China and the world, together with the major cardiovascular disease risk, our findings have important implications for human health. PMID- 29188877 TI - Vitamin D Status and Elevated Red Cell Distribution Width in Community-Dwelling Adults: Results from the National Health and Nutrition Examination Survey 2001 2006. AB - OBJECTIVES: Elevated red cell distribution width (RDW) is associated with morbidity and mortality in community-dwelling individuals. Although RDW is traditionally used to diagnose anemia, it may also be a marker of systemic inflammation. Since vitamin D is a potent modulator of inflammatory cytokines our goal was to investigate whether 25-hydroxyvitamin D levels (25OHD) are associated with RDW in non-hospitalized adults. DESIGN: To investigate this association, we conducted a cross-sectional study. Stepwise multivariable linear and logistic regression models were used to assess the independent association of 25OHD with RDW. Elevated RDW was defined as >14.5%. SETTING: Nationwide sample of non hospitalized adults within the United States. PARTICIPANTS: Individuals from the National Health and Nutrition Examination Survey from 2001-2006. RESULTS: 15,162 individuals comprised the analytic cohort. Mean 25OHD was 24.9 ng/mL (SE 0.4) and the prevalence of elevated RDW was 6.3%. Linear regression analysis, controlling for age, sex, race, mean corpuscular volume, albumin, and neutropenia, demonstrated that 25OHD was inversely associated with RDW (beta=-0.01; 95%CI 0.01 to -0.01). Logistic regression analysis, controlling for the same covariates, also demonstrated an inverse association of 25OHD with elevated RDW (OR 0.96; 95%CI 0.94-0.99). Individuals with 25OHD <30 ng/mL were more likely to have elevated RDW (OR 1.65; 95%CI 1.13-2.40) compared to those individuals with levels >=30ng/mL. CONCLUSIONS: In a nationwide sample of non-hospitalized adults within the United States, low 25OHD was associated with increased likelihood of elevated RDW. Further studies are needed to determine whether optimizing vitamin D status can reduce the prevalence of elevated RDW, and thereby reduce morbidity and mortality in the general population. PMID- 29188875 TI - Intake of a Protein-Enriched Milk and Effects on Muscle Mass and Strength. A 12 Week Randomized Placebo Controlled Trial among Community-Dwelling Older Adults. AB - OBJECTIVES: To investigate the effect of 20 g protein with breakfast and evening meal on muscle mass, muscle strength and functional performance in older adults. DESIGN: A double-blinded randomized controlled study. SETTING: Oslo and Akershus University College of Applied Sciences, Norway. PARTICIPANTS: Healthy community dwelling men and women (>= 70 years) with reduced physical strength and/or performance. INTERVENTION: Subjects were randomly assigned to receive either protein-enriched milk (2 x 0.4 L/d; protein group) or an isocaloric carbohydrate drink (2 x 0.4 L/d; control group) with breakfast and evening meal for 12 weeks. MEASUREMENTS: The primary endpoints were muscle mass measured by dual X-ray absorptiometry, and tests of muscle strength (one repetition maximum test of chest press and leg press) and functional performance (handgrip strength, stair calimb and repeated chair rise). RESULTS: In total, 438 subjects were screened, 50 subjects were randomized and 36 completed the study. Chest press improved significantly in the protein (1.3 kg (0.1-2.5), p=0.03) and the control group (1.5 kg (0.0-3.0), p=0.048), but with no difference between the groups (p=0.85). No significant change in leg press (p=0.93) or muscle mass (p=0.54) were observed between the protein and the control group. Nor did we observe any significant differences in the functional performance tests (p>0.05 for all tests) between the groups. CONCLUSION: Increased protein intake (2 x 20 g/d) did not significantly improve muscle mass, muscle strength or functional performance in healthy older weight stable adults. Whether intake of > 20 g protein to each meal is necessary for preservation of muscle mass and strength in older adults should be further investigated in a larger study. This underscores the need for well designed studies that can differentiate between the effect of protein intake and increased energy. This trial was registered at Clinicaltrials.gov (ID no. NCT02218333). PMID- 29188876 TI - Association of Cortical beta-Amyloid with Erythrocyte Membrane Monounsaturated and Saturated Fatty Acids in Older Adults at Risk of Dementia. AB - OBJECTIVES: We examined the relationships between erythrocyte membrane monounsaturated fatty acids (MUFAs) and saturated fatty acids (SFAs) and cortical beta-amyloid (Abeta) load in older adults reporting subjective memory complaints. DESIGN: This is a cross-sectional study using data from the Multidomain Alzheimer Preventive Trial (MAPT); a randomised controlled trial. SETTING: French community dwellers aged 70 or over reporting subjective memory complaints, but free from a diagnosis of clinical dementia. PARTICIPANTS: Participants of this study were 61 individuals from the placebo arm of the MAPT trial with data on erythrocyte membrane fatty acid levels and cortical Abeta load. MEASUREMENTS: Cortical-to cerebellar standard uptake value ratios were assessed using [18F] florbetapir positron emission tomography (PET). Fatty acids were measured in erythrocyte cell membranes using gas chromatography. Associations between erythrocyte membrane MUFAs and SFAs and cortical Abeta load were explored using adjusted multiple linear regression models and were considered significant at p <= 0.005 (10 comparisons) after correction for multiple testing. RESULTS: We found no significant associations between fatty acids and cortical Abeta load using multiple linear regression adjusted for age, sex, education, cognition, PET-scan to clinical assessment interval, PET-scan to blood collection interval and apolipoprotein E (ApoE) status. The association closest to significance was that between erythrocyte membrane stearic acid and Abeta (B-coefficient 0.03, 95 % CI: 0.00,0.05, p = 0.05). This association, although statistically non-significant, appeared to be stronger amongst ApoE epsilon4 carriers (B-coefficient 0.04, 95 % CI: -0.01,0.09, p = 0.08) compared to ApoE epsilon4 non-carriers (B-coefficient 0.02, 95 % CI: -0.01,0.05, p = 0.18) in age and sex stratified analysis. CONCLUSION: Future research in the form of large longitudinal observational study is needed to validate our findings, particularly regarding the potential association of stearic acid with cortical Abeta. PMID- 29188878 TI - Effect of a 6-Month Brisk Walking Program on Walking Endurance in Sedentary and Physically Deconditioned Women Aged 60 or Older: A Randomized Trial. AB - BACKGROUND: Walking endurance is a predictor of healthy ageing. OBJECTIVE: To examine if a 6-month brisk walking program can increase walking endurance in sedentary and physically deconditioned older women. TRIAL DESIGN: Randomized controlled trial. SETTING: Women recruited from public meetings aimed at promoting physical activity in women aged 60 or older. SUBJECTS: 121 women aged 65.7 +/- 4.3 years, with sedentary lifestyle (Physical Activity Questionnaire for the Elderly score < 9.4), and a 6-minute walking distance (6MWD) below normal value based on their gender, age, and body weight, and weight. METHODS: Women were randomly assigned to a 150 min/week brisk walking program (two supervised sessions and one session on their own per week) for six months (exercisers) (n=61) or a control group with physical activity allowed freely (n=60). OUTCOME: The primary outcome was relative change in 6MWD. RESULTS: 54/61 exercisers and 55/60 control subjects completed the program and data analysis was possible for 51 exercisers and 47 controls. At baseline, 6MWD was on average 23.1% and 22.5% below age-matched norms in exercisers and controls, respectively. Attendance rate for supervised sessions was 92% in exercisers. The 6MWD increased more significantly in exercisers than in controls (mean increase of 41.5% vs 11.0 %; p<0.0001). Over the 6-month program, 38 exercisers (74.5%) vs 5 controls (10.6%) had a 6MWD over the age-matched norm (p<0.0001). Exercisers with the highest tertile of 6MWD improvement (>46%) were those with baseline lowest values of 6MWD (p=0.001) and highest values of body mass index (BMI) (p<0.01). CONCLUSION: Present results support recommendation that brisk walking programs should be encouraged to improve walking endurance in physically deconditioned women aged 60 or older, especially in those with high BMI. PMID- 29188879 TI - Racial Differences in Eating Patterns and Food Purchasing Behaviors among Urban Older Women. AB - OBJECTIVE: To examine differences in diet and food purchasing behaviors between Black and White older women living in urban neighborhoods. DESIGN: Cross sectional observational study. SETTING: Urban neighborhoods in Washington, DC, USA. PARTICIPANTS: Community-dwelling White and Black women of age 65 and older. MEASUREMENTS: Participants were queried on diet via 24-hour recalls, food purchasing habits, their use of neighborhood resources and local travel patterns. Frequency and location of self-reported food purchasing and consumption were compared by race. RESULTS: In 2014 and 2015, 49 White and 44 Black older women were enrolled in the study. Compared to Whites, Blacks reported lower daily caloric intake (mean (SD) 1314 (404) vs. 1529 (448), p=0.02), with a higher percent of calories from protein and fat 1.8 (7.0), p=0.03), and a slightly higher polyunsaturated to saturated fat ratio (p=0.05). Blacks had substantially lower alternate healthy eating index (AHEI) (33.5 (10.2) vs. 43.9 (10.8) of 80 possible points, p<0.001), daily intake (grams) of total fiber (15.3 (8.1) vs. 22.9 (8.5), p<0.001), insoluble fiber (10.8 (6.9) vs. 15.9 (6.5), p<0.001), and soluble fiber (4.5 (2.0) vs. 6.9 (2.8), p<0.001). Blacks had lower intake of micronutrients, alcohol and caffeine. Blacks shopped for groceries less often (4.4 (3.0) vs. 6.2 (3.0) monthly; p=0.006) and spent a longer time traveling to stores (15.8 (9.1) vs. 11.5 (7.2) minutes per trip, p=0.02). A lower percent of Blacks walked to stores (14% vs. 40%, p=0.003) and a higher percent of Blacks rode in a car with someone else (33% vs. 6%, p<0.001). CONCLUSIONS: In an urban setting, food consumption and purchasing behaviors differed substantially between older Black and White women, which should be further investigated and considered to promote healthy eating in older populations. PMID- 29188880 TI - Perspectives on the Causes of Undernutrition of Community-Dwelling Older Adults: A Qualitative Study. AB - OBJECTIVES: Undernutrition is a major health concern particularly in vulnerable older adults. The present study aimed to reveal the causes of undernutrition as reported by community-dwelling older adults. DESIGN: Twenty-five semi-structured interviews and two focus group discussions were performed and analyzed. SETTING: Community-dwelling. PARTICIPANTS: Older adults. MEASUREMENTS: A questionnaire on demographics, Short Nutritional Assessment Questionnaire 65+ and interviews on the potential causes of undernutrition. RESULTS: 33 older adults agreed to participate in the interviews and focus groups. Our findings indicate that a wide variety of causes of undernutrition, both modifiable and non-modifiable, were mentioned by the older adults. Many modifiable causes of undernutrition were reported in the mental, social or food and appetite theme, such as poor food quality provided by meal services, the inability to do groceries, loneliness and mourning. Non-modifiable causes included, forgetfulness, aging, surgery and hospitalization. CONCLUSIONS: This study provides guidance to better understand the underlying causes of undernutrition from an older adult's perspective. The modifiable causes provide specific direction towards practical implications that might decrease or prevent undernutrition. Non-modifiable causes should raise awareness of an increased risk of undernutrition by health professionals in primary and secondary care, caregivers and family members. PMID- 29188881 TI - Malnutrition in Acutely Unwell Hospitalized Elderly - "The Skeletons Are Still Rattling in the Hospital Closet". AB - INTRODUCTION: Malnutrition is common in hospitalized patients with prevalence rates of up to 30% in Australian hospitals with adverse consequences for both the patients and health care services. Despite formulation of nutritional screening protocols, not all hospitalized patients get nutritional screening. Real life screening rates of hospitalized elderly patients are unknown. AIM: The present study explored nutrition screening rate in acutely unwell elderly patients admitted in a large tertiary hospital and how these patients fared depending upon their nutrition status. METHODS: A prospective cross-sectional study involving 205 general medical patients >=60years recruited between November 2014 and November 2015. The number of patients who missed nutrition screening were noted and all patients underwent nutritional assessment by a qualified dietitian using PG-SGA and quality of life was measured using EQ-5D 5L. A survival curve was plotted and multivariate cox proportional hazard model was used to adjust for confounders. RESULTS: Only 99 (49.7%) patients underwent nutritional screening. One hundred and six (53.5%) patients were confirmed as malnourished by PG-SGA. Malnourished patients had significantly longer length of hospital stay and had worse quality of life. Mortality was significantly higher in malnourished patients at one year (23 (21.7%) vs 4 (4.3%); p<0.001) and cox proportional hazard model suggests that malnutrition significantly affects survival even after adjustment for confounders like age, sex, Charlson index and polypharmacy. CONCLUSION: This study confirms that nutrition screening is still suboptimal in elderly hospitalized patients with adverse consequences and suggests need for review of policies to improve screening practices. PMID- 29188882 TI - Nutrient Intake During Diet-Induced Weight Loss and Exercise Interventions in a Randomized Trial in Older Overweight and Obese Adults. AB - OBJECTIVES: Dietary restriction in obese older adults undergoing weight loss may exacerbate nutrient deficiencies common in this group; the nutritional health of older adults is a factor in their quality of life, disability, and mortality. This study examined the effect of an 18-month weight loss program based in social cognitive theory incorporating partial meal replacements, on nutrient intake in older overweight and obese adults. DESIGN: The following analysis is from the Intensive Diet and Exercise for Arthritis (IDEA) trial, a single-blind, randomized controlled trial. Individuals were randomized into one of three 18 month interventions: exercise (E); intensive diet-induced weight loss (D); or intensive diet-induced weight loss plus exercise (D+E). SETTING: The study setting was at a university research facility. PARTICIPANTS: Overweight and obese older adults (n=388; BMI=33.7+/-3.8 kg/m2; 65.8+/-6.1 years) were recruited. INTERVENTIONS: The D and D+E interventions (group mean goal of >=10% loss by 18 months) utilized partial meal replacements (2 meal replacement shakes/day for 6 months). Exercise training for E and D+E was 3 days/week, 60 minutes/day. MEASUREMENTS: Three day food records were collected at baseline, 6-months, and 18 months and analyzed for total energy and macro- and micronutrient intake. Comparisons of dietary intake among treatment groups were performed at 6 and 18 months using mixed linear models. RESULTS: Weight loss at 18-months was 11.3+/ 8.3% (D), 10.3+/-6.8% (D+E), and 1.2+/-4.2% (E). Meal replacements were used by more than 60% (6-months) and 50% (18-months) of D and D+E participants, compared to <=15% for E. Both D and D+E consumed less energy and fat, and more carbohydrates and selected micronutrients than E during follow-up. More than 50% of all participants consumed less than the recommended intake of particular vitamins and minerals. CONCLUSIONS: The diet intervention improved intakes of several nutrients. However, inadequate intake of several vitamins and minerals of concern for older adults suggests they need further guidance to assure adequate intake. PMID- 29188883 TI - Dietary Approach to Stop Hypertension with Sodium Reduction for Chinese Canadians (DASHNa-CC): A Pilot Randomized Controlled Trial. AB - BACKGROUND: There is a lack of culturally sensitive dietary interventions targeting Chinese Canadians despite unhealthy dietary behaviours being identified as the most important modifiable risk factor for hypertension in the Chinese population. AIMS: To determine the feasibility of a culturally sensitive dietary intervention for hypertension control; to examine the potential effects of the intervention on blood pressure and health-related quality of life among Chinese Canadians in community. METHODS: This study was a two-group pilot randomized controlled trial with 8 weeks follow up. Sixty self-identified Chinese Canadians, older than 45 years old and with grade one hypertension but not on antihypertensive medications were recruited in community. The control group received usual care and the intervention group received usual care plus newly developed DASHNa-CC intervention. The DASHNa-CC intervention consisted of a written manual, two classroom sessions, and one telephone booster call to provide healthy dietary and sodium reduction advice, integrated with Traditional Chinese Medicine food therapy recommendations for hypertension control. RESULTS: 618 Chinese Canadians participated in blood pressure screening, and 60 eligible participants recruited. Participants were highly satisfied with the intervention and adhered to the trial protocol. The lost to follow-up rate was 5%. At 8 weeks post-randomization, those in the intervention group had greater reductions in systolic blood pressure [3.8mmHg, t (55) = -1.58, p = 0.12] and higher physical health scores [t (55) = 2.13, p = 0.04] compared to those of the control group. There were no group differences in health care utilization. CONCLUSIONS: It is feasible to deliver the DASHNa-CC intervention in a Chinese Canadian community. The DASHNa-CC intervention may decrease blood pressure and improve health-related quality of life for Chinese Canadians. PMID- 29188884 TI - Model Construction for Biological Age Based on a Cross-Sectional Study of a Healthy Chinese Han population. AB - OBJECTIVES: Biological age (BA) has been proposed to evaluate the aging status in an objective way instead of chronological age (CA). The purpose of our study is to construct a more precise formula of BA in the cross-sectional study based on a largest-ever sample of our studies. This formula aims at better evaluation of body function and exploring the disciplines of aging in different genders and age stages. METHODS: A total of 1,373 healthy Chinese Han (age range, 19-93 years) were recruited from five cities in China, including 581 males and 792 females. Physical examination, blood routine, blood chemistry, and other lab tests were performed to obtain a total of 74 clinical variables. Then, the principal component analysis (PCA) was used to select variables and estimate BA. The BA formula was further validated in a population with some diseases (n=266), including cardiovascular diseases, type 2 diabetes, kidney diseases, pulmonary diseases, cancer and disorders in nervous system. RESULTS: The BA formula was constructed as follows: BA = 0.358 (pulse pressure) + 0.258 (trail making test) - 11.552 (mitral valve E/A peak) + 26.383 (minimum intima-media thickness) + 31.965 (Cystatin C) + 0.163 (CA) - 3.902. In validation of the formula, BAs of patients were older than those of healthy persons. The BA accelerates faster in the middle aged population than in the elderly population (>75 years old). CONCLUSION: This BA formula can reflect health condition changes of aging better than CA in a Chinese Han population. PMID- 29188885 TI - Perceived Resources as a Predictor of Satisfaction with Food-Related Life among Chilean Elderly: An Approach with Generalized Linear Models. AB - OBJECTIVE: The main objective of this study is to show why perceived resources are a strong predictor of satisfaction with food-related life in Chilean older adults. Design, sampling and participants: A survey was conducted in rural and urban areas in 30 communes of the Maule Region with 785 participants over 60 years of age who live in their own homes. The Satisfaction with Food-related Life (SWFL) scale was used. Generalized linear models (GLM) were used for the regression analysis. RESULTS: The results led to different considerations: First, older adults' perceived levels of resources are a good reflection of their actual levels of resources. Second, the individuals rated the sum of the perceived resources as 'highly important' to explain older adults' satisfaction with food related life. Third, SWFL was predicted by satisfaction with economic situation, family importance, quantity of domestic household goods and a relative health indicator. Fourth, older adults who believe they have more resources compared to others are more satisfied with their food-related life. Finally, Poisson and binomial logistic models showed that the sum of perceived resources significantly increased the prediction of SWFL. CONCLUSION: The main conclusion is that perceived personal resources are a strong predictor of SWFL in Chilean older adults. PMID- 29188886 TI - Effects of Body Mass Index on Parasympathetic Nervous System Reactivity and Recovery Following Orthostatic Stress. AB - Vagally mediated heart rate variability (vmHRV), defined as the beat-to-beat fluctuations in a heart series mediated by the vagus nerve, serves as a non invasive index of parasympathetic nervous system (PNS) activity. Lower resting state vmHRV is associated with greater body mass index (BMI), providing a psychophysiological pathway linking obesity with health and disease. However little research has been conducted to examine how BMI may influence PNS reactivity to orthostatic stress. The present study sought to explore this in a sample of 59 individuals (44 females, mean age = 24.37 years, age range 19-65 years). VmHRV was measured throughout the 5-minute baseline (sitting), orthostatic (standing), and recovery (sitting) conditions. Individuals were stratified into low (BMI < 20), moderate (BMI 20-25), and high (BMI > 25) BMI groups. Results indicate that the high BMI group had a greater decrease in vmHRV from baseline to standing in comparison to the moderate BMI group. Furthermore, the low BMI group showed lower vmHRV during recovery compared to baseline, suggesting that these individuals did not fully recover from the standing position. Taken together, these results extend previous literature showing that those with low and high BMI can show different yet maladaptive patterns of vmHRV in response to orthostatic stress. PMID- 29188887 TI - The Influence of Age the BMI and All-Cause Mortality Association: A Meta Analysis. AB - OBJECTIVES: To assess BMI range with the lowest mortality for those aged <65 years and those >=65 years, utilising cohort studies that spanned the entire adult age range. DESIGN: A two-stage random effects meta-analysis of studies that reported mortality in cohorts both >=65 years and <65 years. Setting / Participants: Community living adults aged >=65 and <65 years. RESULTS: Eight studies were included with a total of 370 416 subjects (306 340 aged <65 years; 64 076 >=65 years). In the older age group, mortality risk increased at BMIs lower than 22 (BMI range 21.0-21.9: hazard ratio (HR) (95% confidence interval (CI)): 1.05 (1.03, 1.07)), which was not seen in younger adults. In the younger group, mortality increased from BMI range 28.0-28.9 (HR (95% CI): 1.13 (1.00, 1.29)), but mortality did not tend to increase significantly in the older group at BMIs above 23. CONCLUSION: The recommended healthy weight range is appropriate for younger and middle aged adults but a higher BMI range should be recommended for older adults based on mortality. PMID- 29188889 TI - Vitamin B12 Intake and Related Biomarkers: Associations in a Dutch Elderly Population. AB - BACKGROUND: Vitamin B12 status is measured by four plasma/ serum biomarkers: total vitamin B12 (total B12), holotranscobalamin (holoTC), methylmalonic acid (MMA) and homocysteine (tHcy). Associations of B12 intake with holoTC and tHcy and associations between all four biomarkers have not been extensively studied. A better insight in these associations may contribute to an improved differentiation between vitamin B12 deficiency and a normal vitamin B12 status. OBJECTIVE: This study investigates associations between vitamin B12 intake and biomarkers and associations between biomarkers. DESIGN: In this cross-sectional observational study, levels of total B12, HoloTC, MMA and tHcy were determined in participants of the B-PROOF study: 2919 elderly people (>=65 years, with a mean age of 74.1 years, a mean BMI of 27.1 and 50% women) with elevated tHcy levels (>=12 umol/L). B12 intake was assessed in a subsample. We assessed the association between intake and status with multivariate regression analysis. We explored the dose-response association between B12 intake and biomarkers and the association of total B12 and holoTC with tHcy and MMA with restricted cubic spline plots. RESULTS: A doubling of B12 intake was associated with 9% higher total B12, 15% higher HoloTC, 9% lower MMA and 2% lower tHcy. Saturation of biomarkers occurs with dietary intakes of >5 MUg B12. Spline regression showed that levels of MMA and tHcy started to rise when vitamin B12 levels fall below 330 pmol/L and with HoloTC levels below 100 pmol/L, with a sharp increase with levels of B12 and HoloTC below 220 and 50 pmol/L respectively. CONCLUSIONS: In this study we observed a significant association between vitamin B12 intake and vitamin B12 biomarkers and between the biomarkers. The observed inflections for total B12 and holoTC with MMA and tHcy could indicate cut-off levels for further testing for B12 deficiency and determining subclinical B12 deficiency. PMID- 29188888 TI - Late-Life Body Mass Index, Rapid Weight Loss, Apolipoprotein E epsilon4 and the Risk of Cognitive Decline and Incident Dementia. AB - OBJECTIVES: To examine the effect of late-life body mass index (BMI) and rapid weight loss on incident mild cognitive impairment (MCI) and Alzheimer's disease (AD). DESIGN: Prospective longitudinal cohort study. SETTING: National Alzheimer's Coordinating Center (NACC) Uniform Data Set, including 34 past and current National Institute on Aging-funded AD Centers across the United States. PARTICIPANTS: 6940 older adults (n=5061 normal cognition [NC]; n=1879 MCI). MEASUREMENTS: BMI (kg/m2) and modified Framingham Stroke Risk Profile (FSRP) score (sex, age, systolic blood pressure, anti-hypertension medication, diabetes mellitus, cigarette smoking, prevalent cardiovascular disease, atrial fibrillation) were assessed at baseline. Cognition and weight were assessed annually. RESULTS: Multivariable binary logistic regression, adjusting for age, sex, race, education, length of follow-up, and modified FSRP related late-life BMI to risk of diagnostic conversion from NC to MCI or AD and from MCI to AD. Secondary analyses related late-life BMI to diagnostic conversion in the presence of rapid weight loss (>5% decrease in 12 months) and apolipoprotein E (APOE) epsilon4. During a mean 3.8-year follow-up period, 12% of NC participants converted to MCI or AD and 49% of MCI participants converted to AD. Higher baseline BMI was associated with a reduced probability of diagnostic conversion, such that for each one-unit increase in baseline BMI there was a reduction in diagnostic conversion for both NC (OR=0.977, 95%CI 0.958-0.996, p=0.015) and MCI participants (OR=0.962, 95%CI 0.942-0.983, p<0.001). The protective effect of higher baseline BMI did not persist in the setting of rapid weight loss but did persist when adjusting for APOE epsilon4. CONCLUSIONS: Higher late-life BMI is associated with a lower risk of incident MCI and AD but is not protective in the presence of rapid weight loss. PMID- 29188890 TI - Iberian Cured-Ham Consumption Improves Endothelial Function in Healthy Subjects. AB - OBJECTIVES: Previous studies have shown that dietary components such as oleic acid or polyphenols exert beneficial effects on endothelium. We aimed to assess the impact of regular consumption of Iberian cured-ham (ICH) on endothelial function. DESIGN: An open-label, randomized controlled parallel study. SETTING: Volunteers recruited through advertisements at a hospital in Madrid, Spain. PARTICIPANTS: 102 Caucasian adults (76.8% females) aged 25-55 years, and free from cardiometabolic disease. INTERVENTION: Participants were randomized to an ICH-enriched ad libitum diet or an ad libitum diet without ICH for 6 weeks. Subjects in ICH group were randomly provided with either acorn- or mixed-fed ICH, and followed up for an additional 6-week period under their usual diet. MEASUREMENTS: Clinical parameters, biomarkers of endothelial function and oxidative stress, microvascular vasodilatory response to hyperemia and arterial stiffness were measured before and after the intervention. RESULTS: After 6 weeks, a larger decrease in PAI-1 was observed in subjects consuming ICH compared to the Control group (-6.2+/-17.7 vs. 0.3+/-1.4 ng/ml; p=0.020). Similarly, microvascular vasodilatory response to hyperemia showed a significant increase (112.4+/-391.7 vs. -56.0+/-327.9%; p=0.007). However, neither oxidative stress, hemodynamic nor clinical parameters differed significantly over the study. Additionally, after stopping ICH consumption, improvements in PAI-1 remained for 6 additional weeks with respect to baseline (p=0.006). CONCLUSION: The present study demonstrates, for the first time, that regular consumption of ICH improves endothelial function in healthy adults. Strategies aimed to preserve or improve the endothelial function may have implications in vascular aging beyond the prevention of the atherothrombotic disease. PMID- 29188891 TI - Intake of Fruit and Vegetables and the Incident Risk of Cognitive Disorders: A Systematic Review and Meta-Analysis of Cohort Studies. AB - OBJECTIVES: No quantitative assessment has been performed to specifically link the consumption of fruit and vegetables with the incident risk of cognitive disorders. METHODS: We searched the PubMed and the Embase databases (both from the inception to June 13th, 2016) for records that report the intake of fruit and vegetables and the risk of developing cognitive disorders (Alzheimer's disease, dementia, and cognitive decline/impairment). A generic inverse-variance method (random-effects model) was used to combine the relative risks (RRs) and 95% confidence intervals (CIs). To explore the potential sources of heterogeneity, we performed the subgroup and meta-regression analyses by pre-specified characteristics. RESULTS: We identified 6 cohorts involving a total of 21,175 participants. The pooled analysis showed that consumption of fruit and vegetables was inversely associated with the incident risk of cognitive disorders, and the pooled RR (95% CI) was 0.74 (0.62, 0.88), with evidence of significant heterogeneity (I2 =68%). Furthermore, we found that the significant heterogeneity might be attributed to the ethnic difference. CONCLUSION: Further large prospective studies should be performed to quantify the potential dose-response patterns of fruit and/or vegetables intake and to explore the role of fruit or vegetables consumption separately on cognitive disorders in different populations. PMID- 29188892 TI - Dyslipidemia as a Potential Moderator of the Association between Hearing Loss and Depressive Symptoms. AB - OBJECTIVES: Knowledge about moderation of the association between hearing loss and depression is scant. We investigated dyslipidemia as a potential moderator of the association between hearing/hearing loss and depressive symptoms. DESIGN: Cross-sectional study. SETTING: General population-based cohort in France (SU.VI.MAX 2; 2007-2009). PARTICIPANTS: N= 4,307 adults (mean age = 61.5 +/- 6.1 y; 59.6% women). MEASUREMENTS: A score >= 16 on the Center for Epidemiologic Studies Depression Scale defined presence of depressive symptoms. Mean hearing level for each ear was defined as the pure-tone average of the following thresholds: 0.5, 1.0, 2.0 and 4.0 kHz; the value for the better hearing ear was retained for analysis. Hearing loss was defined as inability to hear at thresholds >= 25 dB in both ears. A subjective measure of perceived hearing loss was also used. Serum triglyceride, total-, LDL- and HDL-cholesterol concentrations were assessed in fasting blood samples and established cutoffs were used in multivariable logistic regression models. The interaction between hearing/hearing loss (independent variables) and each of the four lipid parameters was tested. RESULTS: Even though the interaction tests regarding LDL-, HDL- cholesterol, and triglyceride status were statistically significant, the subgroup analyses revealed few significant and somewhat unexpected findings. In fact, among individuals with low LDL-cholesterol, unlike their counterparts with high LDL-cholesterol, there was an inverse association between hearing level in the better hearing ear and depressive symptoms (OR= 0.94; 95% CI: 0.89-0.99). Regarding the subjective measure of hearing, a few of the dyslipidemia-moderated associations were statistically significant, albeit not all in the predicted direction. CONCLUSIONS: The findings provide some support for moderation of the association between hearing/hearing loss and depressive symptoms by dyslipidemia, with important lipid-specific and hearing measure-specific differences. The results could serve as impetus for future investigations in order to identify and target population subgroups with increased vulnerability to depression in the context of both sensory disability and aging. PMID- 29188894 TI - Vitamin D and the Mechanisms, Circumstances and Consequences of Falls in Older Adults: A Case-Control Study. AB - OBJECTIVES: To determine i) whether cases of elderly fallers had lower serum 25 hydroxyvitamin D (25OHD) concentration than controls without history of falls; and ii) whether serum 25OHD concentration was associated with specific mechanisms, circumstances and consequences of falls. DESIGN: Case-control study with a 1:2 ratio. SETTING: Geriatric ward of the University Hospital of Angers, France, between February 2012 and March 2014. PARTICIPANTS: 216 inpatients (72 cases and 144 age- and gender-matched controls). MEASUREMENT: Falls were defined as involuntary events causing the person to the ground or other lower level. The main mechanisms, circumstances and consequences of falls were identified using standardized questionnaires. Vitamin D deficiency was defined as serum 25OHD concentration <=25nmol/L. Age, gender, body mass index, polypharmacy, use antihypertensive drugs, use psychoactive drugs, disability, cognitive performance, serum concentrations of parathyroid hormone, creatinine and albumin, and season of evaluation were used as potential confounders. RESULTS: 216 participants (72 cases and 144 controls) were included in the study. There was no between-group difference in the prevalence of vitamin D deficiency (P=0.176). After adjusting for confounding factors, vitamin D deficiency was positively associated with falls (OR=4.03, P=0.014). Finally, the fallers with vitamin D deficiency exhibited more often orthostatic hypotension (68.8% against 33.3%, P=0.039) and a history of recurrent falls (85% against 50%, P=0.002) than those without vitamin D deficiency. CONCLUSION: This case-control study reported that vitamin D deficiency was associated with falls in older inpatients. There was a greater prevalence of orthostatic hypotension and of the reccurrence of falls among fallers with vitamin D deficiency, suggesting that vitamin D may influence the conditions predisposing to falls rather than the fall by itself. PMID- 29188893 TI - Therapeutic Role of Punica Granatum (Pomegranate) Seed Oil Extract on Bone Turnover and Resorption Induced in Ovariectomized Rats. AB - CONTEXT: Postmenopausal osteoporosis is mostly caused by increased bone remodeling resulting from estrogen deficiency. Hormone replacement therapy (HRT) is used to prevent osteoporosis, but it increases the risk for breast cancer, thromboembolism, strokes, and heart attacks. Pomegranate seed oil extract (SOE) is rich in phytoestrogen and antioxidant compounds. OBJECTIVES: To evaluate the therapeutic role of SOE against bone turnover, resorption and osteoporosis induced in ovariectomized rats as a postmenopausal model and comparing the results with those from Generic CycloProgynova drug (D). DESIGN: The study used western albino rats undergo bilaterally ovariectomization as a model for postmenopausal. SETTING: The study took part in a laboratory setting. ANIMALS: Forty female western albino rats (age: 3-4 months) weighing 150-180 gm. MEASUREMENTS: Rats were divided into four groups, 10 rats each; SC-group: Sham control = untreated and unovariectomized rats; OVX-group = ovariectomized rats; (OVX-SOE) and (OVX-D) groups = OVX rats were treated with SOE and D, respectively. Bone markers (BMs) especially osteocalcin (BGP), alkaline phosphatase (ALP), tartarate resistance acid phosphatase (TRAcP), bone weight, bone calcium concentration, serum electrolytes (calcium, sodium and potassium) and serum estradiol (E2) level and histopathological examination of bones were determined. Also lipid profile, uric acid, prothrombin time (INR) and liver and kidney functions were measured to evaluate the adverse effects of SOE and D. RESULTS: In OVX group the activities of ALP and TRAcP and the levels of BGP, serum calcium, sodium and body weight were significantly higher (p<=0.05) than SC group, while bone calcium concentration, bone mass, serum E2 and potassium level as well as uterus mass were significantly lower (p<=0.05). Also histopathological results revealed that the outer cortical bone became thinner, while the cancellous bone trabeculae lost their normal architecture. Moreover in OVX group lipid profile and uric acid levels were significantly higher (p<=0.05) than SC group, but there were no significant changes (p<=0.05) in INR level, liver and kidney functions. Treatment of OVX rats with SOE or D for 12 weeks improved both the architecture of bones as shown from the histopathological results and BMs, serum electrolytes and E2 levels (p<=0.05) which approached SC-group. Moreover after treatment of OVX rats with SOE the levels of lipid profile and uric acid were improved and approached SC-group, while liver function became significant lower (p<=0.05) than SC-group. Also there were no significant changes (p<=0.05) in kidney functions and INR of (OVX-SOE), OVX and SC groups. In contrast in (OVX D) group the levels of lipid profile, liver and kidney functions, uric acid and INR were significantly higher (p<=0.05) than those of OVX and SC groups. CONCLUSION: The results of this study show that SOE has therapeutic effects on osteoporosis, while it has no adverse effects on lipid profile, uric acid, liver and kidney functions when compared to HRT. SOE offers a promising alternative in the design of new strategies in nutritional management of age-related bone complications. PMID- 29188895 TI - Supplementation of Mussel Peptides Reduces aging Phenotype, Lipid Deposition and Oxidative Stress in D-Galactose-Induce Aging Mice. AB - OBJECTIVES: Aging is associated with glucose and lipid metabolism disorder. We aimed to examine the effects of mussel peptides on protecting against aging by regulating glucose and lipid metabolism. METHODS: For the aging model, d galactose (200 mg/kg) was administered subcutaneously to 8-month-old mice for 8 weeks. Mussel peptides (1,000 mg/kg) were simultaneously administered by intragastric gavage. The glucose and lipid metabolism profiles, aging phenotype and peroxisome proliferator-activated receptors (PPARs) expression in the liver and adipose tissue of ICR mice were measured. RESULTS: D-galactose-treated mice showed pronounced fat deposition and impaired glucose and lipid homeostasis, along with increased oxidative damage and aging. Mussel peptides improved metabolic status by reducing serum glucose and triglyceride levels, insulin resistance and hepatic free fatty acid, as well as enhancing serum high-density lipoprotein (HDL) level and hepatic glycogen content, accompanied with amelioration of aging phenotype and fat deposition. Moreover, mussel peptides ameliorated oxidative stress in aged liver tissues and promoted expression of peroxisome proliferator activated receptors alpha (PPARalpha) and gamma (PPARgamma) in liver and adipose tissues. CONCLUSIONS: These results indicate that mussel peptides protect against lipid metabolic disorders associated with aging via maintaining oxidative stress homeostasis and elevated expression levels of PPARs.

AB - OBJECTIVES: This study aimed to assess the independent associations of serum levels of vitamin B12 and plasma concentrations of homocysteine with gait speed decline. DESIGN, SETTING, PARTICIPANTS: This study utilized longitudinal analysis of participants 50 years or older from The Baltimore Longitudinal Study of Aging, N=774. MEASUREMENTS: Gait speed (m/s) was assessed using the 6-meter usual pace test. Vitamin B12 and homocysteine concentrations were collected using standard clinical protocols. Linear mixed effects regression was stratified by baseline age category (50-69, 70-79, and >=80 years old). RESULTS: Mean follow-up time for the total study sample was 5.4 +/- 2.0 years. No association between vitamin B12 and gait speed decline over the follow-up time for any age group was found. Elevated homocysteine concentrations were associated with decline in gait speed after adjustment for covariates (50-69: beta= -0.005, p=.057; 70-79: beta= 0.013, p<.001, >=80: beta= -0.007, p=.054). CONCLUSION: Homocysteine and vitamin B12 are inversely related, yet only homocysteine was associated with gait speed decline in this population of healthy older adults. Given these results, future research should be directed towards investigating the relationship in populations with greater variation in vitamin B12 concentrations and other mechanisms influencing homocysteine concentrations. PMID- 29188897 TI - Better Body Composition and Lipid Profile Can Be Associated with Vitamin D Status in Spanish Elderly? The PHYSMED Study. AB - Studies have shown that vitamin D deficiency increases the risk for lipid metabolism disorders, but this relationship has provided inconsistent results in elderly. Thus the aim was to assess the association between body composition and blood lipid profile levels on serum 25-hydrovitamin D [25(OH)D] concentration in Spanish elderly. A cross-sectional multicentre study was carried out in 383 participants (58.2% females) aged of 55-88 years. Fasting blood samples analyzed serum concentrations of 25(OH)D, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG) and total cholesterol (TC). Body composition parameters (fat mass, fat free mass) were obtained by bioimpedance, waist circumference (WC), physical activity and vitamin D intake were also evaluated. BMI, fat mass and total fat mass were lower in vitamin D sufficient subjects than vitamin D insufficient and deficient subjects, but this difference was not significant (p>0,05). Those with vitamin D adequate levels also showed lower TC/HDL ratio than those who had inadequate (insufficient or deficient) vitamin D levels (p=0.04). Significant association between 25(OH)D and BMI, waist circumference, total muscle mass, TC/HDL-c ratio, HDL and TG (for all p<= 0.05) was found after controlling for some confounders. Subjects with inadequate HDL levels (<40mg/dL) showed 1.7 times higher odds than vitamin D deficiency than those with adequate HDL levels (>60mg/dL) (95% CI= 1.10 to 2.85 p= 0.017) and WC was negatively associated with vitamin D status odds ratio of 0.98 (0.96 to 1.00; p= 0.04). Vitamin D concentration was positively correlated with HDL-c and total muscle mass, as well as negatively correlated with WC, LDL-c/HDL-c and TC/HDL-c independently of age, gender and some confounders. PMID- 29188898 TI - Influence of High-Fat Diet on Bone Tissue: An Experimental Study in Growing Rats. AB - BACKGROUND: The relationship between obesity and bone tissue remains contradictory, especially when the effect of high-fat diet is assessed in experimental models. The aim of this study was to evaluate the effects of high fat diet on bone metabolism of growing rats. METHODS: Twenty weaned female Wistar rats were equally divided into two groups: SD (standard diet) and HFD (high-fat diet with 60 % of energy as fat). After five weeks of the two diets, the rats were euthanized, and the liver, blood and bones extracted. The liver was analysed for malondialdehyde (MDA) and reduced glutathione (GSH) concentrations. Blood was analysed by the ELISA method for osteoprotegerin (OPG) and tumour necrosis factor ligand superfamily member 11 (TNFSF11/RANKL). The bone tissue was analysed by dual-energy X-ray absorptiometry (DXA), mechanical tests, computed microtomography, histological quantitative analysis and scanning electron microscopy. The gene expressions of PPAR-gamma Runx-2, RANKL and Cathepsin-K were also evaluated. RESULTS: HFD caused an increase in the MDA concentration, indicating oxidative stress. It also increased the expression of PPAR-gamma, which is the gene that is related to adipocyte differentiation. There was an increase in BMD of the tibia of animals fed with the HFD, but other microstructural and mechanical properties were maintained unaltered. In addition, there were no changes in the gene expressions related to the differentiation of osteoblasts and osteoclasts, as well as no changes to the biochemical markers of bone formation and bone resorption. CONCLUSION: Liver and gene parameters are changed in response to the HFD. However, although there was an increase in BMD, the microstructure and function of the bone did not change after a 5-week HFD. PMID- 29188899 TI - Utility of Three Prognostic Risk Scores in Predicting Outcomes in Elderly Non Malignant Patients after Percutaneous Gastrostomy. AB - BACKGROUND/OBJECTIVES: Percutaneous endoscopic gastrostomy is a method of providing enteral feeding to patients who cannot take adequate oral nutrition. The aims of this study were to determine the performance of malnutrition and mortality scoring systems for predicting short and long-term mortality in elderly patients who had undergone gastrostomy procedure due to non-malignant conditions. DESIGN: Retrospective cohort study. SETTING: University hospital in Turkey. PARTICIPANTS: 155 individuals aged 65 and older principally hospitalized for non malignant diseases and require percutaneous endoscopic gastrostomy. MEASUREMENTS: "Geriatric Nutritional Risk Index", "Malnutrition Universal Screening Tool" (MUST) and "Portsmouth-Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity" (P-POSSUM) scores were calculated. The ability of these scores to predict mortality was determined. RESULTS: The mean survival period was 9.59+/-6.0 months and mortality rate was 80.6%. The performance of "Geriatric Nutritional Risk Index" was superior to MUST and P POSSUM in predicting long-term survival of gastrostomy patients; 94.1% of patients were alive with a cut-off value of 90 for "Geriatric Nutritional Risk Index" (sensitivity: 92% CI 85.9-95.6 and specificity: 90% CI 74.3-96.5). Survival analysis showed that patients (n=7) with a "Geriatric Nutritional Risk Index" score of > 98 before the gastrostomy had the longest survival time, while patients (n=102) with a "Geriatric Nutritional Risk Index" score of < 82 had the worst outcome. CONCLUSIONS: A scoring system such as "Geriatric Nutritional Risk Index" should be considered as a risk scoring system for predicting early and late mortality at gastrostomy and also assist in making decisions such as timing of gastrostomy procedure. PMID- 29188900 TI - Effects of Aerobic and Resistance Training Combined with Fortified Milk on Muscle Mass, Muscle Strength, and Physical Performance in Older Adults: A Randomized Controlled Trial. AB - OBJECTIVES: Fortified milk and resistance training (RT) increase muscle mass, muscle strength, and physical performance in older adults, but it remains unclear whether RT combined with aerobic training (AT) would have stronger effects on these outcomes. The purpose of this study was to examine the effects of aerobic and resistance training (ART) combined with fortified milk consumption on muscle mass, muscle strength, and physical performance in older adults. DESIGN: Open labeled randomized controlled trial. SETTING: University of Tsukuba. PARTICIPANTS: Fifty-six older adults aged 65-79. INTERVENTION: Participants were randomly allocated into resistance training (RT + fortified milk, n = 28) and aerobic and resistance training (ART + fortified milk, n = 28) groups. All participants attended supervised exercise programs twice a week at University of Tsukuba and ingested fortified milk every day for 12 weeks. Skeletal muscle index ([SMI]: appendicular lean mass/height2) was assessed using dual-energy X-ray absorptiometry as a muscle mass measure. One-repetition maximum strength was measured using four kinds of resistance training machines (chest press, leg extension, leg curl, and leg press) as muscle strength measures. Sit-to-stand and arm curl tests were also assessed as physical performance measures. MEASUREMENTS: The primary measurements were muscle mass and strength. The secondary outcomes were physical performance, blood samples, habitual diet, habitual physical activity, and medication use. RESULTS: Although the muscle strength and physical performance measures significantly improved in both groups, SMI significantly improved in only the RT group. There was no significant difference in the change in SMI and muscle strength measures between the two groups. However, the change in sit-to-stand and arm curl measures in the ART group were significantly higher than those in the RT group. CONCLUSIONS: These results suggest that AT before RT combined with fortified milk consumption has similar effects on skeletal muscle mass and strength compared with RT alone, but it may be a more useful strategy to improve physical performance in older adults. Although the mechanism of our intervention is uncertain, our program would be an effective prevention for sarcopenia in older adults. PMID- 29188901 TI - Food Insecurity among Veterans: Findings from the Health and Retirement Study. AB - OBJECTIVES: We examined the prevalence of food insecurity in an older population, specifically assessing factors associated with food insecurity among U.S. military Veterans. METHODS: Data from the 2012 wave of the Health and Retirement Study and the 2013 Health Care and Nutrition Mail Survey of 2560 male participants (1254 Veterans) were used to estimate the prevalence of food insecurity and to identify significant predictors of food insecurity among male Veterans. RESULTS: Among male Veterans, 6.4% reported food insecurity, compared to 11.9% of male non-veterans (p < 0.01). Younger age, difficulty with daily activities and depression were significantly associated with increased odds of food insecurity among male Veterans aged 50 to 64. In male Veterans age 65 years and older, current smoking, a psychiatric diagnosis and depression were significantly associated with increased odds of food insecurity. CONCLUSIONS: This study identified significant factors that may be used to target interventions to improve nutritional status among older male Veterans. PMID- 29188902 TI - Inadequate Glycaemic Control and Therapeutic Management of Adults over 65 Years Old with Type 2 Diabetes Mellitus in Spain. AB - OBJECTIVES: The glycaemic goals for older patients with type 2 diabetes mellitus (DM) are recommended to avoid an HbA1c levels <7%. The purpose of this study was to analyse the glycaemic control and therapeutic management of older adults (>=65 years) with type 2 DM. DESIGN: Pooled analysis of patients enrolled in three Spanish cross-sectional epidemiological studies. SETTING: The study was conducted between 2009 and 2011 by primary care or specialist physicians. PARTICIPANTS: A total of 7,269 patients aged >=65 years with type 2 DM. MEASUREMENTS: Sociodemographic, medical history, lifestyle habits, biochemical laboratory parameters, comorbidities, type 2 DM complications, and pharmacological treatment data collected from medical records. RESULTS: In total, data from 7,269 patients were analysed (mean age 73.4 years old; 48.4% male). A total of 10.9% of patients had HbA1c levels >=8.5% and 43.2% <7%. The most common comorbidities were hypertension (82.0%) and dyslipidaemia (76.6%). The microvascular complications were mainly diabetic nephropathy (23.6%) and retinopathy (19.3%). Oral antidiabetic drugs (OADs) were taken by 70.5% of patients (sulphonylureas 65.3%), 4.1% were taking insulin alone and 25.4% took both insulin and an OAD. Half of the patients (51.0%) were taking a combination of OADs. CONCLUSION: In conclusion, more than half of older patients with type 2 DM had unsatisfactory management: approximately one in ten had inadequate glycaemic control (HbA1c >=8.5%) despite hypoglycaemic drugs and four in ten were potentially overtreated (HbA1c <7%). PMID- 29188904 TI - Utilizing the DSM-5 Anxious Distress Specifier to Develop Treatment Strategies for Patients With Major Depressive Disorder. PMID- 29188903 TI - Medication review by a clinical pharmacist at the transfer point from ICU to ward: a randomized controlled trial. AB - WHAT IS KNOWN AND OBJECTIVE: Drug-related problems (DRPs) occur frequently in hospitalized patients. Patient discharge from the intensive care unit (ICU) to a non-ICU ward is one of the most challenging and high-risk transitions of care due to the number of medications, and the complexity and acuity of the medical conditions that characterize this patient group. Pharmacists could play an important role in preventing DRPs. This study was undertaken to evaluate the impact on the number and severity of drug-related problems by assigning a clinical pharmacist to the transfer process from ICU to wards. METHODS: The study was a randomized controlled multicentre trial conducted at the Hospital Network of Antwerp between December 2010 and January 2012. The clinical pharmacist performed a medical review in both the intervention and control group. Recommendations for drug therapy changes were immediately communicated in the intervention group but were kept blinded in the control group. The primary outcome was expressed as the number of implemented recommendations for drug therapy changes. Differences between groups were calculated using mixed effects binary logistic regression. RESULTS: Drug-related problems were found in the medical records of 360 of the 600 participants (60%). A total of 743 recommendations could be made, 375 in the intervention group and 368 in the control group. 54.1% of these problems were adjusted on time in the intervention group vs. 12.8% in the control group. Of 743 recommendations, 24.8% were judged by the expert group as major, 13.1% as moderate, 53.4% as minor and 8.9% as having no clinical impact. The odds of implementing recommendations of drug therapy changes in the intervention group were 10 times the odds of implementing recommendations of drug therapy changes in the control group (odds ratio = 10.1; 95%CI [6.3-16.1]; P < 0.001), even after accounting for differences in types of DRP between the groups (odds ratio = 15.6; 95%CI [9.4-25.9]; P < 0.001). WHAT IS NEW AND CONCLUSION: The integration of a clinical pharmacist at the transfer point from ICU to ward led to a significant reduction in DRPs. PMID- 29188905 TI - Review and Meta-Analysis of Epidemiologic Studies of Adult Bipolar Disorder. AB - OBJECTIVE: To test whether rates of bipolar disorder (BD) have changed over time or vary across geographic regions after adjusting for design features meta analyzing epidemiologic studies reporting BD prevalence in adults worldwide. DATA SOURCES: Searches in PubMed and PsycINFO using the terms (epidemiology OR community OR prevalence) AND (mania OR "bipolar disorder" OR cyclothymi*) AND adult and backward searches from published reviews were conducted. STUDY SELECTION: Eighty-five epidemiologic studies published in English from 1980 onward that reported prevalence rates for BD or mania for subjects >= 18 years old were included. DATA EXTRACTION: We coded BD prevalence, method of data collection, diagnostic criteria, year of study, country, and quality of study design and data reporting. Meta-regression tested whether sample characteristics influenced prevalence rates using the metafor package in R. RESULTS: Eighty-five effect sizes, from 44 countries, from studies spanning the years 1980-2012, included 67,373 people with BD. Lifetime prevalence for BD spectrum was 1.02% (95% CI, 0.81%-1.29%). Prevalence was moderated by the inclusion of BD not otherwise specified (P = .009) and by geographic region; rates from Africa and Asia were less than half of those from North and South America. Rates did not change significantly over 3 decades after controlling for design features. CONCLUSIONS: The overall prevalence rate is consistent with historical estimates, but rates vary significantly across studies. Differences in methodology contribute to the perception that rates of BD have increased over time. Rates varied markedly by geographic region, even after controlling for all other predictors. Research using consistent definitions and methods may expose specific factors that confer risk for BD. PMID- 29188906 TI - Is Psychiatric Epidemiology Still Counting? PMID- 29188907 TI - Prescribing Patterns in a Psychiatrically Referred Sample of Youth With Autism Spectrum Disorder. AB - OBJECTIVE: The aim of this study was to examine the pattern of psychopharmacologic interventions in a psychiatrically referred sample of youth with autism spectrum disorder (ASD). METHODS: This retrospective chart review aimed at collecting demographic and clinical information, including data on DSM IV-TR criteria-based psychiatric disorders and related current medication treatment and response. Data were collected in December 2011. Clinicians identified the target disorder for each medication and any adverse events. Level of psychopathology and therapeutic response was assessed by the clinician-rated Clinical Global Impressions scale (CGI). RESULTS: Psychiatrically referred youth with ASD (n = 54) suffered from multiple psychopathologies (mean = 2.3) and had a marked level of morbidity (range of baseline CGI-Severity of Illness mean scores, 4.3-5.6). The most prevalent psychopathology was ADHD (83%), anxiety disorders (67%), bipolar spectrum disorder (43%), and mood disorder not otherwise specified (44%). The majority (80%) of the subjects received combination therapy (mean +/- SD number of psychotropic medications = 3 +/- 1.5). Forty percent of the participants responded on all treatment target symptoms (CGI-Improvement scale score <= 2), and an additional 10% experienced response versus nonresponse on a relatively greater number of target symptoms. Half of the subjects reported an adverse event, most commonly weight gain (28%) and sedation (12%), both from antipsychotic medication use. CONCLUSIONS: Psychiatrically referred youth with ASD suffer from multiple highly impairing psychiatric disorders that require combination pharmacotherapy. These findings highlight the need for further research to guide clinical decision-making and treatment. PMID- 29188908 TI - Anticholinergic Burden and Cognition in Older Patients With Schizophrenia. AB - OBJECTIVE: Older individuals with schizophrenia are at risk of being treated with anticholinergic medications due to the prevalence of medical comorbidities and polypharmacy. High anticholinergic burden impairs cognition and is a risk factor for Alzheimer's dementia. Thus, we assessed the impact of anticholinergic burden on Alzheimer's dementia-related and schizophrenia-related cognitive functions in older patients with schizophrenia. METHODS: Anticholinergic burden was measured using the Anticholinergic Cognitive Burden scale (ACB) in 60 community-dwelling patients aged >= 50 years who met DSM-IV criteria for schizophrenia between May 2007 and November 2011. Cognitive domains affected early in the course of Alzheimer's dementia were assessed using the Cambridge Neuropsychological Test Automated Battery (CANTAB) Alzheimer's Dementia Battery and the Repeatable Battery for the Assessment of Neuropsychological Status. Two CANTAB tests of executive function were used to assess deficits common in schizophrenia. Regression analyses were used to assess the relationships between anticholinergic burden and cognition. A receiver operating characteristic curve was constructed to determine an ACB cutoff score to identify those at risk of cognitive impairment. RESULTS: ACB scores were associated with spatial working (P = .04) and immediate (P = .004) memory and visuospatial ability (P = .02) and showed a trend toward association with impaired learning (P = .06), but were not associated with attention, executive function, language, or reaction time. An ACB cutoff score of <= 1.5 can detect cognitive impairment with a sensitivity of 90.3% and specificity of 48.3%. CONCLUSIONS: High anticholinergic burden contributes to specific cognitive deficits in older individuals with schizophrenia that resemble those commonly observed early in the course of Alzheimer's dementia. The ACB is a potentially useful screening tool that can help identify patients at risk of developing anticholinergic-related cognitive impairment.

PMID- 29188911 TI - [Physical structure, human resources, and health care quality indicators in public hospital emergency departments in the autonomous communities of Madrid and Catalonia: a comparative study]. AB - OBJECTIVES: To compare the general, structural, and organizational characteristics of public hospital emergency departments in the Spanish autonomous communities of Madrid and Catalonia. MATERIAL AND METHODS: Descriptive survey-based study covering 3 areas of inquiry: general hospital features (18 questions), structural features of the emergency department (14 questions), and organizational and work-related policies of the emergency department (30 questions). Hospitals were grouped according to complexity: local hospitals (level 1), high-technology or referral hospitals (levels 2-3). RESULTS: We studied 26 hospital departments in Madrid (21, levels 2-3; 5, level 1) and 55 in Catalonia (24, levels 2-3; 31, level 1). Hospitals in Madrid are in newer buildings (P=.002), have more beds on conventional wards and in critical care units (P<.001, both comparisons), are more often affiliated with a university (P<.001), and serve larger populations (P=.027). The emergency departments in Madrid have larger surface areas available for clinical care and more cubicles for preliminary evaluations and observation beds (P=.001, all comparisons). Hospitals in Madrid also attended a larger median number of emergencies (P<.001). More physicians were employed in Catalonia overall, but the numbers of physician- and nurse-hours per hospital were higher in Madrid, where it was more usual for physicians to work exclusively in the emergency department (92.5% in Madrid vs 56.8% in Catalonia, P<.001). However, fewer of the employed physicians had permanent contracts in Madrid (30.5% vs 75.1% in Catalonia, P<.001). The ratio of resident physicians to staff physicians differs between the 2 communities on afternoon/evening, night, and holiday shifts (3:1 in Madrid; 1:1 in Catalonia). CONCLUSION: The physical and functional structures of hospital emergency departments in the communities of Madrid and Catalonia differ significantly. The differences cannot be attributed exclusively to geographic location. PMID- 29188912 TI - [Medication reconciliation errors according to patient risk and type of physician prescriber identified by prescribing tool used]. AB - OBJECTIVES: To study the frequency of medication reconciliation errors (MREs) in hospitalized patients and explore the profiles of patients at greater risk. To compare the rates of errors in prescriptions written by emergency physicians and ward physicians, who each used a different prescribing tool. MATERIAL AND METHODS: Prospective cross-sectional study of a convenience sample of patients admitted to medical, geriatric, and oncology wards over a period of 6 months. A pharmacist undertook the medication reconciliation report, and data were analyzed for possible associations with risk factors or prescriber type (emergency vs ward physician). RESULTS: A total of 148 patients were studied. Emergency physicians had prescribed for 68 (45.9%) and ward physicians for 80 (54.1%). A total of 303 MREs were detected; 113 (76.4%) patients had at least 1 error. No statistically significant differences were found between prescriber types. Factors that conferred risk for a medication error were use polypharmacy (odds ratio [OR], 3.4; 95% CI, 1.2-9.0; P=.016) and multiple chronic conditions in patients under the age of 80 years (OR, 3.9; 95% CI, 1.1-14.7; P=.039). CONCLUSION: The incidence of MREs is high regardless of whether the prescriber is an emergency or ward physician. The patients who are most at risk are those taking several medications and those under the age of 80 years who have multiple chronic conditions. PMID- 29188913 TI - [A new artificial intelligence tool for assessing symptoms in patients seeking emergency department care: the Mediktor application]. AB - OBJECTIVES: To analyze agreement between diagnoses issued by the Mediktor application and those of an attending physician, and to evaluate the usefulness of this application in patients who seek emergency care. MATERIAL AND METHODS: Prospective observational study in a tertiary care university hospital emergency department. Patients with medical problems and surgical conditions (surgery and injuries) who did not require immediate emergency care responded to the Mediktor questions on a portable computer tablet. The software analyzed the answers and provided a list of 10 possible preliminary diagnoses in order of likelihood. The patient and the attending physician were blinded to the list to so that the usual care process would not be altered. The level of agreement between the physician's diagnosis and the Mediktor diagnosis was analyzed. RESULTS: A total of 1015 patients were included; 622 cases were considered valid for study. Cases were excluded if the patients did not meet the inclusion criteria, they did not have a discharge diagnosis, they had a final diagnosis expressed as a symptom or their final diagnosis was not included in the Mediktor database. The physician's diagnosis (the gold standard) coincided with one of the 10 MEDIKTOR diagnoses in 91.3% of the cases, with one of the first 3 diagnoses in 75.4%, and with the first diagnosis in 42.9%. Sensitivity was over 92% and specificity over 91% in the majority of common diagnostic groups; the kappa statistic ranged from 0.24 to 0.98. CONCLUSION: The Mediktor application is a reliable diagnostic aid for the most prevalent problems treated in a hospital emergency department. The general public finds it easy to use. PMID- 29188914 TI - [Vernakalant in hospital emergency practice: safety and effectiveness]. AB - OBJECTIVES: To study the effectiveness and safety of vernakalant for restoration of sinus rhythm in patients with atrial fibrillation (AF) in routine hospital emergency department care, and to evaluate factors associated with a more effective response. MATERIAL AND METHODS: Prospective multicenter cohort study enrolling consecutive patients who were administered vernakalant for medical cardioversion of AF between September 2014 through March 2016 in 5 hospitals in the Spanish autonomous community of Valencia. RESULTS: We studied 165 cases. The median (interquartile range) was 68 years (56-77) years. Cardioversion with vernakalant was effective in 77.6% (95% CI, 71.1%-84%). The median time to conversion was 8 ( 6-12) minutes after a first dose and 34 (22-62) minutes after a second dose. A prior history of cardiac insufficiency was nonsignificantly less common in patients who converted with vernakalant (6.3%) than in those who did not (18.9%) (adjusted odds ratio [OR], 0.45 [95% CI, 0.13-1.56]; P=.208). Having no prior history of AF was nonsignificantly related to greater effectiveness (in 54.7% vs in 35.1% with prior AF). Duration less than 12 hours was significantly associated with greater effectiveness (83.6% vs 59.5%; adjusted OR, 2.76 [95% CI, 1.12-6.80]; P=.028). Adverse events were reported for 30 patients. None of the events had clinically important consequences, and in only 2 cases (1.2%) was it necessary to suspend treatment. CONCLUSION: Vernakalant is effective and safe for restoring sinus rhythm in the hospital emergency department. PMID- 29188915 TI - [Occupational aspects of emergency medicine practice in Catalonia: the OPENCAT opinion survey]. AB - OBJECTIVES: To gather information on the contracting and training of members of the Catalan Society of Emergency Medicine (SoCMUE) who work in emergency medicine and services in Catalonia. To survey their opinions on certain aspects of resource availability and working conditions. MATERIAL AND METHODS: Cross sectional descriptive study based on a survey sent to SoCMUE members. We studied the opinions of 5 types of respondent: hospital physicians, out-of-hospital physicians, hospital nurses, out-of-hospital nurses, and emergency medical technicians. Responses were grouped to compare the opinions of physicians and nurses and workers in hospital and prehospital settings. RESULTS: We received 616 responses from 1273 members (48.4% response rate). More physicians than nurses come from outside Catalonia and have contracts specifically linked to emergency care; in addition, physicians have done less postgraduate training in emergency medicine. More hospital staff than prehospital staff have permanent contracts linked to the department where they work. More hospital physicians are specialized in internal medicine than in family and community medicine. The opinion that emergency services are inadequately staffed was widespread. Most respondents believed that patient transport is good or adequate. However, respondents working in prehospital services expressed a lower opinion of transport. Great difficulty in combining work with family (life achieving work life balance) was expressed by 13.5% overall, and more often by hospital staff. Some type of aggression was experienced by 88.2%; 60% reported the event to superiors. Nurses reported aggression more often than physicians. A police report was filed by 10.1%. CONCLUSION: Emergency medicine working conditions can be improved in Catalonia according to members of SoCMUE. Relations between groups of professionals are not optimum in some aspects. PMID- 29188916 TI - [Medication errors in a hospital emergency department: study of the current situation and critical points for improving patient safety]. AB - OBJECTIVES: To determine the frequency of medication errors and incident types in a tertiary-care hospital emergency department. To quantify and classify medication errors and identify critical points where measures should be implemented to improve patient safety. MATERIAL AND METHODS: Prospective direct observation study to detect errors made in June and July 2016. RESULTS: The overall error rate was 23.7%. The most common errors were made while medications were administered (10.9%). We detected 1532 incidents: 53.6% on workdays (P=.001), 43.1% during the afternoon/evening shift (P=.004), and 43.1% in observation areas (P=.004). CONCLUSION: The medication error rate was significant. Most errors and incidents occurred during the afternoon/evening shift and in the observation area. Most errors were related to administration of medications. PMID- 29188917 TI - [Implementation of the Hartford Consensus and Tactical Combat Casualty Care recommendations in emergency services: a review of the literature]. AB - en: Recent terrorist attacks involving active shooters or improvised explosive devices have shown that traditionally sequenced emergency management leads to delays in attending victims and suboptimal outcomes. Tactical medicine, a new concept in prehospital care, emerged from experience attending the wounded in combat zones, where the Tactical Combat Casualty Care (TCCC) recommendations are applied. TCCC targets 3 main causes of preventable death in combat: bleeding from extremities, tension pneumothorax, and airway obstruction. A change in the delivery of emergency care during terrorist attacks is now required if we are to improve survival rates. To that end, strategies based on the TCCC and Hartford Consensus recommendations have been developed. Both these approaches describe procedures for both first responders and medical professionals to apply in areas under threat.

AB - Acute hospital admission provides an excellent opportunity to address poor oral health in older people, a group rarely seen by dental professionals and for who oral health activity in hospital is inconsistent and generally suboptimal. This two-part article explores oral hygiene and mouth care provision for older adults in acute hospitals. The first article presented the findings of a literature review exploring oral and dental disease in older adults, the importance of good oral health and mouth care, and the current situation. The second article explores clinical recommendations. A change in philosophy is needed to embed oral care as an essential component of holistic practice. More research is needed to determine the best ways to assess and treat oro-dental problems in older people, and promote and restore their oral health in hospitals. Great potential exists to innovate and develop new ways of providing care to this group. PMID- 29188928 TI - Factors that influence older people's engagement with digital health technology. AB - Digital health technology (DHT) encompasses a wide range of applications and interventions with the potential to address the health needs of an increasingly ageing population. Older people's engagement with DHT depends on many factors, and this article summarises understanding of the barriers and facilitators to DHT uptake and continued use among older people. Older people's confidence in using digital technology, their perceptions of personal benefit from DHT, its design, and the support they receive from health professionals and carers in using DHT all affect their level of engagement. Understanding these barriers and facilitators among the older population creates ways to enable greater numbers to benefit from DHT. This article provides information for those who work with, or design digital health interventions for, older people to help them to influence older people's engagement with these rapidly evolving healthcare innovations.

The trust's practice development facilitator supported care home staff to develop clinical competencies while observing residents' emergency department (ED) attendance trends. RESULTS: After introduction of the programme, avoidable ED attendances were reduced by 31% ( n =309) compared with the previous year, cost per capita was reduced by L314,340, reliance on community nursing was reduced, and the health and experience of the care home population were improved. CONCLUSION: ED attendances and reliance on community nursing reduced, identifying a compelling need for continuing partnership, training and facilitation between the trust and independent sector. PMID- 29188930 TI - Should hepatocellular cancer by screened in Finland? AB - Almost 2 000 people die each year from the adverse effects of alcohol use in Finland. Liver cirrhosis is the cause of death in half of the cases. Although the annual risk of hepatocellular cancer for a cirrhosis patient is 1 to 4%, more than 95% of the deaths result from complications caused by the cirrhosis, not the cancer. It seems that nontargeted screening of hepatocellular cancer for those affected with alcoholic cirrhosis or nonalcoholic steatohepatitis is not cost effective. Screening may, however, be advisable when the risk of cancer is high, provided that treatment of a detected cancer is possible. PMID- 29188931 TI - Treatment of hypertrophic scars and keloids. AB - Differentiation of a hypertrophic scar from a keloid is important with regard to the planning of treatment. Keloids arise following any skin injury and may grow disproportionately large as compared with the original wound. Treatment of keloids is challenging both for the patient and the attending physician. Treatment of hypertrophic scars aims to abate the symptoms and accelerate scar maturation. The goal in the treatment of keloids is excision of the keloid or stopping its growth, lessening of symptoms and avoidance of recurrence. PMID- 29188932 TI - The evolving treatment of ANCA-associated vasculitides. AB - Prevention of organ damage and maintenance of long-term remission are the principal goals for treatment of ANCA-associated vasculitides. This can be accomplished by early diagnosis and swift initiation of remission-inducing agents. Outcome has improved but relapses and glucocorticoid- and cyclophosphamide-related toxicity are still major concerns. For remission induction in generalized disease a combination of glucocorticoids and cyclophosphamide or rituximab is used. Rituximab is suitable especially for younger patients with fertility concerns and when cyclophosphamide avoidance otherwise is desirable. In the treatment of relapses and refractory disease, rituximab has proved effective. As maintenance treatment rituximab prevents relapses more effectively than azathioprine. PMID- 29188933 TI - Ascites in newborns - a diagnostic challenge. AB - Isolated fetal ascites is a rare finding in prenatal ultrasound examination. The finding is always aberrant and requires further exploration. More than half of fetal ascites findings are associated with structural anomalies. Other causes include prenatal infections and genetic disorders. The cause and time of detection of ascites have an influence on the baby's prognosis. In spite of careful examinations the cause of ascites frequently remains open during pregnancy. During the first hours of life the baby needs intensive care, and when necessary, etiologic exploration will be simultaneously continued. PMID- 29188934 TI - Treatment of adult acute myeloid leukemia. AB - The aim of this study was to analyze the treatment results of 180 adult AML patients treated at Turku University Hospital from 2002 to 2012. 124 patients received intensive therapy according to the protocol of the Finnish Leukemia Group. 86% of them achieved remission. 46 patients underwent allogeneic stem cell transplantation which was beneficial for high and intermediate risk disease. 60 - 70% of patients under 60 years old can be cured. The genetic profile of the disease, patient age and treatment response had a significant impact on survival. Our treatment results are comparable with data in literature. PMID- 29188935 TI - A good start for scientific supervision. AB - Clinical research work is mostly supervised besides daily work. Good time management skills are in fact an essential prerequisite for success, also influenced by various qualities of the supervisor and the supervisee. One pattern will not work in all supervisory relationships. Functional communication plays a particularly central role. Attention should be paid on the regularity, quality and effectiveness of supervisory discussions. On the other hand, group supervision has proven to be effective and will also facilitate the continuity of supervision. Goals and desires set for the partners can be structured by applying supervision contracts.

AB - Approximately 15 to 40% of cerebral infarctions and transient ischemic attacks (TIA) are of cardiac origin. Knowledge of a significant cardiac disease arouses the suspicion of cardiogenic embolism, but its diagnosis requires identification of the source of embolism. Atrial fibrillation is the most common cause of cardiogenic embolism, and should be actively sought after an ischemic cerebrovascular attact. The detection of atrial fibrillation or an intracardiac thrombus in these patients requires initiation of permanent anticoagulant therapy. Transesophageal echocardiography (TEE) has proven to be more sensitive than transthoracic echocardiography (TTE) in detecting certain possible cardiogenic sources of embolism. PMID- 29188941 TI - Distal myopathies in Finnish patients. AB - Distal myopathies are a group of rare muscular dystrophies comprising more than 20 different genetic entities. The first distal myopathy in Finland, tibial muscular dystrophy, was identified more than 20 years ago. Muscle weakness predominantly affects the feet and hands, although variable weakness can be detected clinically and on muscle MRI in the proximal muscles in the later stages of the disease. Advanced molecular genetic techniques have enabled identification of several distinct distal myopathies in Finland. The clinical findings of different distal myopathies overlap, but there are also distinguishable differences that might help final genetic diagnostics. PMID- 29188942 TI - HIV infection and cancer. AB - Cancers in HIV-infected patients are divided into the AIDS-defining and non-AIDS defining cancers. In the era of effective antiretroviral therapy there has been a significant decrease in the incidence of AIDS-defining cancers, whereas the number of non-AIDS defining cancers is on the rise. This is partly explained by the frequent occurrence of conventional risk factors for cancers, but also HIV infection itself seems to further increase the risk. If an HIV-infected person is diagnosed early enough, his/her life expectancy corresponds to that of the general population. Therefore the treatment goal of cancers in HIV-infected patients should be the same as for HIV negative subjects. Antiretroviral agents have significant drug-drug interactions with many other medicines. These must always be taken into account when planning the treatment of HIV-infected patients. PMID- 29188943 TI - Could obesity be an infectious disease? AB - The accomplishments in combating the obesity epidemic have thus far been insufficient. Indeed, the background to the increase in overweight and obesity is more complex than is generally anticipated. Recent scientific data suggest that the gut microbiota affects two main causes of obesity: energy harvest and storage from the diet, thereby increasing energy efficiency, and low-grade inflammatory response and impairment of gut barrier function. Consequently, considerable research interest is currently focusing on characterizing and manipulating the gut microbiota in attempt to reverse the intergenerational progression of obesity and its comorbidities. The proof of causality requires clinical interventions in well-characterized populations and documentation of the mechanisms. PMID- 29188944 TI - Emicizumab Prophylaxis in Hemophilia A with Inhibitors. PMID- 29188945 TI - Elevated liver enzymes - what next? AB - Owing to laboratory automation, elevated liver enzymes are increasingly found in persons who are either asymptomatic or present with vague symptoms. The majority of slightly elevated liver enzymes detected in Finland result from excessive alcohol use, a drug or non-alcoholic fatty liver disease. On the other hand, disregarding pathological liver enzymes may lead to a delay of the treatment of a liver disease. In addition to careful anamnesis and status, systematic targeting of investigations is often the quickest way to correct diagnosis and assessment of need for treatment. PMID- 29188946 TI - A jaundiced patient at the emergency department. AB - Jaundice is a common cause for seeking medical attention at an emergency department. The doctor on call should be able to recognize patients whose jaundice requires emergency investigations and treatment in specialized care. Most patients can be treated electively on an urgent referral. Ultrasound scan of the liver will in most cases clarify whether a liver disease or a biliary tract obstruction is in question, and whether the patient should be referred to an internist or a surgeon. PMID- 29188947 TI - Emicizumab Prophylaxis in Hemophilia A with Inhibitors. PMID- 29188948 TI - What to do when I find a focal lesion in the liver? AB - A focal lesion in a healthy liver of a person not having cancer is almost always benign. Diagnosis is often achieved on the basis of anamnesis and imaging findings. A histologic specimen is required in the case of suspected malignant tumor or hepatocellular adenoma. Magnetic resonance imaging is the primary investigation for an unresolved focal lesion of a cancer patient, and the histologic specimen will, when necessary, be taken only after this. Early detection of metastases of colorectal cancer in particular is important, since metastases that have spread to the liver or lungs may be operable. A focal lesion in a cirrhotic liver is either a regenerative nodule or hepatocellular carcinoma. PMID- 29188949 TI - Fatty liver - so what? AB - Approximately one third of the Finnish adult population are affected with overweight-related non-alcoholic fatty liver disease (NAFLD). NAFLD can appear as a simple fat accumulation in the liver of the liver, but in some individuals the condition may advance to non-alcoholic steatohepatitis (NASH) and even to liver cirrhosis. In many cases, NAFLD is detected as an incidental finding. In differential diagnosis, the most common alternatives are alcohol use, drugs and viral hepatites. For a patient with NAFLD, the risk factors of cardiovascular diseases should be investigated and the possibility of having NASH and liver fibrosis assessed. Targeted therapy for NASH is not yet available. PMID- 29188950 TI - Diagnosis for liver fibrosis - noninvasively. AB - Noninvasive tests are utilized in chronic liver diseases to assess excessive connective tissue. Blood tests such as the N-terminal peptide of procollagen (PIIINP) and APRI (ASAT/platelet count) measure the formation and degradation of connective tissue or liver function. Elastography (Fibroscan) is based on the propagation of ultrasound in liver tissue, accelerated by fibrosis: the results are more sensitive and accurate than those based on blood tests. Reliable detection of severe fibrosis and cirrhosis is possible with Fibroscan along with determining normal liver tissue.

AB - The underlying cause of ascites should always be treated if possible. Adhering to a low-salt diet is most important in the treatment of ascites. Diuretics are used in the treatment of clinically established and abundant ascites. The first-line drug in diuretic therapy is spironolactone, when necessary in combination with furosemide. The most important complications of ascites are hepatorenal syndrome and spontaneous bacterial peritonitis. The development of ascites lowers the quality of life, and is associated with significant mortality. Although new groundbreaking therapies are not available, prognosis of the patients is expected to be improved through optimization of current therapies.

PMID- 29188954 TI - Pregnant hepatitis B carrier. AB - While screening for viral hepatitides is not carried out among women of reproductive age in Finland, maternity clinics offer all pregnant women screening for hepatitis B during early pregnancy. A hepatitis B carrier should discuss the timing of pregnancy. In general, pregnancy does not influence the course of hepatitis B. The most significant route of transmission is still the perinatal one, from the mother to the newborn infant. The younger the age when the infection is contracted, the higher is the risk of it becoming chronic and complicated. The risk of transmission correlates with the mother's serum HBV-DNA level and also with HBeAg positivity. At the beginning of the third trimester tenofovir decreases the replication of the virus and prevents the newborn infant from infection.

AB - Vitamin K is not only essential for the synthesis of coagulation factors in the liver, but it also strengthens the bones and prevents calcification of the arteries. These effects are mediated through the same mechanism, i.e. carboxylation of Gla target proteins. The discovery of novel Gla proteins that are not associated with blood coagulation or calcium metabolism indicates that vitamin K has additional effects in the pancreas and the central nervous system, for example. As dietary supplements, vitamin K1 of plant origin and vitamins K2 of bacterial origin may exert different effects. PMID- 29188967 TI - Liraglutide and Renal Outcomes in Type 2 Diabetes.

In this article we deal with the use of Artemisiae as medicinal plants through the ages, and several pharmacologically active compounds can be obtained from species of the genus Artemisia. We will particularly focus on two medicinally interesting species of Artemisiae - sweet wormwood and absinthe - as well as two pharmacologically significant compounds found in them, artemisin and thujone. PMID- 29188969 TI - Etiology of acute pancreatitis. AB - Acute pancreatitis (AP) is a common disease. In Finland, the most common etiological factors are alcohol abuse and biliary stone disease. Often the etiology of AP is multifactorial. AP may also occur as a complication after ERCP, pancreatic operation or ultrasound guided biopsy. It is important to find out the etiological factors to be able to prevent a recurrence of AP. It is estimated that only 5 - 10% of AP-cases should be declared as idiopathic. Anamnesis of alcohol consumption, medication, family history, injuries, and disease history should reveal many of the risk factors. The initial radiological imaging is ultrasound, which can be repeated to increase the sensitivity for detecting gallstones as the etiological factor. In certain cases MRCP, computed tomography or endoscopic ultrasound are needed. PMID- 29188970 TI - The Science of Pain. A guide to prehospital pain management.

AB - In many cases the decisions on drug therapy during pregnancy have to be made without evidence-based information about the effectiveness and safety of the treatment. While few drugs are known with certainty to be harmful for fetal development, the evidence for evaluating harm to the fetus is insufficient for the majority of drugs. The differentiation of fetal organs takes place during the early weeks of pregnancy, whereby it is imperative that the mother's medication be revised already when planning a pregnancy. A drug should primarily be chosen, for which experience has accumulated about its use during pregnancy and is not suspected or known to be associated with adverse effects. PMID- 29188973 TI - Antimicrobial peptides - a part of innate immunity. AB - Antimicrobial peptides (AMP) are evolutionary ancient molecules produced by nearly all living organisms, both prokaryotic and eukaryotic cells. More than 2000 AMPs have now been identified. These peptides are produced by most human cell types, such as those in the skin and mucous membranes and blood. Each tissue has a different spectrum of AMPs. Antimicrobial capacity depends on the structural characteristics such as charge and amphiphilicity that allow the insertion and/or penetration of AMP into the membranes of microorganisms or other cells. AMPs may have importance in the pathogenesis of neurodegenerative diseases and type 2 diabetes. The most investigated AMPs are defensins and cathelicidin LL 37.

They are being widely initiated also within bariatric, hepatic and pancreatic surgery. The programs aim at an increasingly better well being of surgical patients by avoiding procedures which slow down the recovery and favoring those that promote it. Informing the patient is also an essential part of the programs. Effective pain management avoiding opioids, early started oral nutrition, and mobilization immediately after the operation prevent postoperative decreased intestinal motility and nausea. At best, the programs will guarantee the patients' excellent recovery and shorten the length of stay on the ward. PMID- 29188978 TI - Hands On: Product Reviews From Street Crews.

AB - Ion channel dysfunctions of the muscular cell membrane are usually inheritable, rare diseases. They may become manifest as relatively mild symptoms of muscle stiffness and pain, myotonia or paralysis. We describe two young patients who had an inherited ion channel disease of the muscular cell membrane with mild symptoms. The first patient had a chloride channel dysfunction of the muscular cell membrane, the second one a sodium channel dysfunction. In electromyography findings typical of the respective ion channel disease were detected in both patients. Closer examination of the patients' myotonic sequences occurring in electromyography of the relaxed muscle revealed differences that already enable the evaluation of the type of ion channel disease.

Healthy persons may have low amplitude physiological action tremor without any functional handicap, contrary to the disabling pathologic tremor. There are numerous types of tremor, and their etiology is poorly known. Tremor can at best be alleviated by drug therapy, but the response may abate with time. Deep brain stimulation has recently been increasingly utilized in the treatment of drug-resistant tremor in various neurologic diseases. PMID- 29188985 TI - Is it possible to improve memory with drugs in health people? AB - The development of general medication for memory loss in healthy people has proven difficult. The brain harbors a number of parallel memory systems, which further involve different and separate stages of processing. The action of these stages is modified partly by the same mediators having, however, different optimum levels in distinct processes. Thus for instance stress hormones, powerfully supporting storage in long-term memory, will in similar concentrations impair implicit memory. A number of memory-enhancing drugs are available, but they are usually effective only individually and in tailored doses. PMID- 29188986 TI - Pushing the Resolving Power of Tyndall-Powell Gate Ion Mobility Spectrometry over 100 with No Sensitivity Loss for Multiple Ion Species. AB - Ion gate is a key buildup for drift tube ion mobility spectrometry (IMS) and its combination with mass spectrometry. Bradbury-Nielsen gate, as the most commonly used ion gate in IMS, possesses a distinct ion mobility discrimination effect due to its depletion features. This impedes the scaling of the ion gate opening time to improve the separation capability of IMS while keeping its sensitivity for multiple ion species. In this work, a Tyndall-Powell gate (TPG) simply composed of two identical wire grids was used to develop an ion gate with nearly no ion mobility discrimination for IMS. Experimental results showed that the TPG features a gate region where the electric field for opening the gate could be enhanced to effectively solve the ion mobility discrimination problem related to it. Meanwhile, enhancing that electric field enabled the TPG-IMS to keep a resolving power over 106 at 100 degrees C for ion peak with a signal-to-noise ratio up to 800. With that TPG-IMS, baseline separation of two ion peaks, the hydronium and the acetone monomer peaks with a reduced mobility difference of only 0.04 cm2 V-1 s-1, was achieved with no sensitivity loss for the least mobile acetone dimer ions. PMID- 29188987 TI - Multifunctional Moth-Eye TiO2/PDMS Pads with High Transmittance and UV Filtering. AB - This work reports a facile fabrication method for constructing multifunctional moth-eye TiO2/polydimethylsiloxane (PDMS) pads using soft nano-imprinting lithography and a gas-phase-deposited thin sacrificial layer. Mesoporous TiO2 nanoparticles act as an effective UV filter, completely blocking high-energy UVB light and partially blocking UVA light and forming a robust TiO2/PDMS composite pad by allowing the PDMS solution to easily fill the porous TiO2 network. The paraboloid-shaped moth-eye nanostructures provided high transparency in the visible spectrum and also have self-cleaning effects because of nanoroughness on the surface. Furthermore, we successfully achieved a desired multiscale-patterned surface by partially curing select regions using TiO2/PDMS pads with partial UVA ray blockers. The ability to fabricate multifunctional polymeric pads is advantageous for satisfying increasing demands for flexible and wearable electronics, displays, and solar cells. PMID- 29188988 TI - Determination of Urinary Metabolites of the Emerging UV Filter Octocrylene by Online-SPE-LC-MS/MS. AB - Octocrylene (OC) is an emerging UV filter, which is used in the majority of sunscreens as well as other personal care products (PCP) and consumer products. Its presence in various environmental matrices has been reported. However, information on the internal OC exposure in humans is not available, due to the lack of appropriate biomarkers of exposure and analytical methods. Here, we describe a rugged, precise, and accurate analytical method for the determination of three OC metabolites (ester hydrolysis and alkyl chain oxidation products) in human urine by stable isotope dilution analysis. Urine samples are incubated with beta-glucuronidase (E. coli K12) and then analyzed by liquid chromatography electrospray ionization-triple quadrupole-tandem mass spectrometry with online turbulent flow chromatography for sample cleanup and analyte enrichment (online SPE-LC-MS/MS). Syntheses of analytical standards, including deuterium-labeled internal standards, are also described. In a pilot study, we investigated the applicability of the metabolites as biomarkers of exposure in urine samples from the general population (n = 35). OC metabolites were detected in 91% of the samples, with the highest concentrations for three individuals having used sunscreen within 5 days prior to sample collection. We will apply the method in future human biomonitoring studies for OC exposure and risk assessment. PMID- 29188990 TI - Reactive Dopamine Leads to Triple Trouble in Nigral Neurons. PMID- 29188989 TI - Identification and Experimental Characterization of an Extremophilic Brine Pool Alcohol Dehydrogenase from Single Amplified Genomes. AB - Because only 0.01% of prokaryotic genospecies can be cultured and in situ observations are often impracticable, culture-independent methods are required to understand microbial life and harness potential applications of microbes. Here, we report a methodology for the production of proteins with desired functions based on single amplified genomes (SAGs) from unculturable species. We use this method to resurrect an alcohol dehydrogenase (ADH/D1) from an uncharacterized halo-thermophilic archaeon collected from a brine pool at the bottom of the Red Sea. Our crystal structure of 5,6-dihydroxy NADPH-bound ADH/D1 combined with biochemical analyses reveal the molecular features of its halo-thermophily, its unique habitat adaptations, and its possible reaction mechanism for atypical oxygen activation. Our strategy offers a general guide for using SAGs as a source for scientific and industrial investigations of "microbial dark matter." PMID- 29188991 TI - Self-Powered Electrostatic Filter with Enhanced Photocatalytic Degradation of Formaldehyde Based on Built-in Triboelectric Nanogenerators. AB - Recently, atmospheric pollution caused by particulate matter or volatile organic compounds (VOCs) has become a serious issue to threaten human health. Consequently, it is highly desirable to develop an efficient purifying technique with simple structure and low cost. In this study, by combining a triboelectric nanogenerator (TENG) and a photocatalysis technique, we demonstrated a concept of a self-powered filtering method for removing pollutants from indoor atmosphere. The photocatalyst P25 or Pt/P25 was embedded on the surface of polymer-coated stainless steel wires, and such steel wires were woven into a filtering network. A strong electric field can be induced on this filtering network by TENG, while both electrostatic adsorption effect and TENG-enhanced photocatalytic effect can be achieved. Rhodamine B (RhB) steam was selected as the pollutant for demonstration. The absorbed RhB on the filter network with TENG in 1 min was almost the same amount of absorption achieved in 15 min without using TENG. Meanwhile, the degradation of RhB was increased over 50% under the drive of TENG. Furthermore, such a device was applied for the degradation of formaldehyde, where degradation efficiency was doubled under the drive of TENG. This work extended the application for the TENG in self-powered electrochemistry, design and concept of which can be possibly applied in the field of haze governance, indoor air cleaning, and photocatalytic pollution removal for environmental protection. PMID- 29188993 TI - Programmable Peptide-Cross-Linked Nucleic Acid Nanocapsules as a Modular Platform for Enzyme Specific Cargo Release. AB - Herein we describe a modular assembly strategy for photo-cross-linking peptides into nucleic acid functionalized nanocapsules. The peptides embedded within the nanocapsules form discrete nanoscale populations capable of gating the release of molecular and nanoscale cargo using enzyme-substrate recognition as a triggered release mechanism. Using photocatalyzed thiol-yne chemistry, different peptide cross-linkers were effectively incorporated into the nanocapsules and screened against different proteases to test for degradation specificity both in vitro and in cell culture. By using a combination of fluorescence assays, confocal and TEM microscopy, the particles were shown to be highly specific for their enzyme targets, even between enzymes of similar protease classes. The rapid and modular nature of the assembly strategy has the potential to be applied to both intracellular and extracellular biosensing and drug delivery applications.

PMID- 29188992 TI - Tracking the Catalytic Cycle of Adenylate Kinase by Ultraviolet Photodissociation Mass Spectrometry. AB - The complex interplay of dynamic protein plasticity and specific side-chain interactions with substrate molecules that allows enzymes to catalyze reactions has yet to be fully unraveled. Top-down ultraviolet photodissociation (UVPD) mass spectrometry is used to track snapshots of conformational fluctuations in the phosphotransferase adenylate kinase (AK) throughout its active reaction cycle by characterization of complexes containing AK and each of four different adenosine phosphate ligands. Variations in efficiencies of UVPD backbone cleavages were consistently observed for three alpha-helices and the adenosine binding regions for AK complexes representing different steps of the catalytic cycle, implying that these stretches of the protein sample various structural microstates as the enzyme undergoes global open-to-closed transitions. Focusing on the conformational impact of recruiting or releasing the Mg2+ cofactor highlights two loop regions for which fragmentation increases upon UVPD, signaling an increase in loop flexibility as the metal cation disrupts the loop interactions with the substrate ligands. Additionally, the observation of holo ions and variations in UVPD backbone cleavage efficiency at R138 implicate this conserved active site residue in stabilizing the donor phosphoryl group during catalysis. This study showcases the utility of UVPD-MS to provide insight into conformational fluctuations of single residues for active enzymes.

PMID- 29188997 TI - Carbon Nanotubes as Etching Masks for the Formation of Polymer Nanostructures. AB - We investigate the interaction of carbon nanotubes (CNTs) embedded in a polymer matrix [poly(methyl methacrylate) (PMMA)] with Ar plasma, which results in the formation of PMMA nanostructures, as CNTs act as an etching mask. Because of the large differences in the Ar ion sputtering yields between CNTs and PMMA, PMMA lines with the width comparable to that of CNTs and as high as 20 nm (for single walled CNTs) or 80 nm (for multiwalled CNTs) can be obtained after repeated exposure of CNT/PMMA films to Ar plasma. We also follow the etching process by investigating changes in the IV characteristics and Raman spectra of CNTs after each exposure to Ar plasma, which shows progressive defect generations in CNTs while they maintain structural integrity long enough to act as the etching mask for PMMA underneath. We demonstrate that the PMMA nanostructure patterns can be transferred to a different polymer substrate using nanoimprinting. PMID- 29188996 TI - a-Factor Analogues Containing Alkyne- and Azide-Functionalized Isoprenoids Are Efficiently Enzymatically Processed and Retain Wild-Type Bioactivity. AB - Protein prenylation is a post-translational modification that involves the addition of one or two isoprenoid groups to the C-terminus of selected proteins using either farnesyl diphosphate or geranylgeranyl diphosphate. Three crucial enzymatic steps are involved in the processing of prenylated proteins to yield the final mature product. The farnesylated dodecapeptide, a-factor, is particularly useful for studies of protein prenylation because it requires the identical three-step process to generate the same C-terminal farnesylated cysteine methyl ester substructure present in larger farnesylated proteins. Recently, several groups have developed isoprenoid analogs bearing azide and alkyne groups that can be used in metabolic labeling experiments. Those compounds have proven useful for profiling prenylated proteins and also show great promise as tools to study how the levels of prenylated proteins vary in different disease models. Herein, we describe the preparation and use of prenylated a-factor analogs, and precursor peptides, to investigate two key questions. First, a factor analogues containing modified isoprenoids were prepared to evaluate whether the non-natural lipid group interferes with the biological activity of the a-factor. Second, a-factor-derived precursor peptides were synthesized to evaluate whether they can be efficiently processed by the yeast proteases Rce1 and Ste24 as well as the yeast methyltransferase Ste14 to yield mature a-factor analogues. Taken together, the results reported here indicate that metabolic labeling experiments with azide- and alkyne-functionalized isoprenoids can yield prenylated products that are fully processed and biologically functional. Overall, these observations suggest that the isoprenoids studied here that incorporate bio-orthogonal functionality can be used in metabolic labeling experiments without concern that they will induce undesired physiological changes that may complicate data interpretation. PMID- 29188998 TI - Transcriptional Activity of Arsenic-Reducing Bacteria and Genes Regulated by Lactate and Biochar during Arsenic Transformation in Flooded Paddy Soil. AB - Organic substrates and biochar are important in controlling arsenic release from sediments and soils; however, little is known about their impact on arsenic reducing bacteria and genes during arsenic transformation in flooded paddy soils. In this study, microcosm experiments were established to profile transcriptional activity of As(V)-respiring gene (arrA) and arsenic resistance gene (arsC) as well as the associated bacteria regulated by lactate and/or biochar in anaerobic arsenic-contaminated paddy soils. Chemical analyses revealed that lactate as the organic substrate stimulated microbial reduction of As(V) and Fe(III), which was simultaneously promoted by lactate+biochar, due to biochar's electron shuttle function that facilitates electron transfer from bacteria to As(V)/Fe(III). Sequencing and phylogenetic analyses demonstrated that both arrA closely associated with Geobacter (>60%, number of identical sequences/number of the total sequences) and arsC related to Enterobacteriaceae (>99%) were selected by lactate and lactate+biochar. Compared with the lactate microcosms, transcriptions of the bacterial 16S rRNA gene, Geobacter spp., and Geobacter arrA and arsC genes were increased in the lactate+biochar microcosms, where transcript abundances of Geobacter and Geobacter arrA closely tracked with dissolved As(V) concentrations. Our findings indicated that lactate and biochar in flooded paddy soils can stimulate the active As(V)-respiring bacteria Geobacter species for arsenic reduction and release, which probably increases arsenic bioavailability to rice plants.

AB - An apparently rigid dibenzothiophene-bridged zinc(II)/magnesium(II) bisporphyrin host (1M) has been explored for an accurate determination of the absolute configuration of a large series of amino alcohols. At lower substrate concentration, a 1:1 sandwich complex is formed which, upon addition of excess of substrate, converts to the 1:2 host-guest complex with complete inversion of the CD exciton couplet. The intensities of the couplet vary widely just by changing the metal ion (Zn vs Mg) and also vary between 1:1 and 1:2 host-guest complexes. Crystallographic characterizations are reported here for both 1:1 sandwich and 1:2 host-guest complexes using the same pair of host and guest, for the first time, which enable us to scrutinize the structural and geometrical changes systematically in rationalizing their optical properties. The intensity of the CD couplet is largely dependent on how strongly the substrate binds with the host and also their mode of binding. No CD couplet is observed in the spectral region of porphyrin absorption when substrate binds in either exo-endo or exo-exo fashion in the 1:2 host-guest complex. However, intermolecular H bonding between two encapsulated substrates in the 1:2 host-guest complex stabilizes the endo endo conformer in which two porphyrin macrocycles are forced to be oriented in a clockwise/anticlockwise direction to produce an intense CD couplet. Such an endo endo binding of (S)-2-aminobutan-1-ol (S-AB) has resulted in a highly intense CD couplet with 1Mg, while no chiroptic response was observed upon changing the metal to zinc, since S-AB would then bind in an exo-endo form. With an increase in the bulk of the substrate, the endo-endo form first transforms into an exo endo form which, upon further increase in the bulk of the substrate, converts into an exo-exo complex.

AB - On the basis of preparation and characterization of [Fe]-H2ase models (2-COCH2-6 HOCH2C5H3N)Fe(CO)2L (A, L = eta1-SCOMe; B, L = eta1-2-SC5H4N), the chemical reactivities of A and B with various electrophilic and nucleophilic reagents have been investigated, systematically. Thus, when A reacted with 1 equiv of MeCOCl in the presence of Et3N in MeCN to give the eta2-SCOMe-coordinated acylation product (2-COCH2-6-MeCO2CH2C5H3N)Fe(CO)2(eta2-SCOMe) (1), treatment of A with excess HBF4.Et2O in MeCN gave the cationic MeCN-coordinated complex [(2-COCH2-6 HOCH2C5H3N)Fe(CO)2(MeCN)](BF4) (2). In addition, when 2 was treated with 1 equiv of 2,6-(p-4-MeC6H4)2C6H3SK or PPh3 in CH2Cl2 to give the thiophenolato- and PPh3 substituted derivatives (2-COCH2-6-HOCH2C5H3N)Fe(CO)2[2,6-(p-MeC6H4)2C6H3S] (3) and [(2-COCH2-6-HOCH2C5H3N)Fe(CO)2(PPh3)](BF4) (4), treatment of B with 1 equiv of PMe3 or P(OMe)3 in THF afforded the phosphine- and phosphite-substituted complexes (2-COCH2-6-HOCH2C5H3N)(eta1-2-SC5H4N)Fe(CO)2L (5, L = PMe3; 6, L = P(OMe)3). Interestingly, in contrast to A, when B reacted with excess HBF4.Et2O in MeCN to afford the BF3 adduct [2-COCH2-6-HO(BF3)CH2C5H3N]Fe(CO)2(eta1-2 SC5H4N) (7), reaction of B with 1 equiv of p-MeC6H4COCl in the presence of Et3N in MeCN gave not only the expected 2-acylmethyl-6-p-toluoyloxomethylpyridine containing complex (2-COCH2-6-p-MeC6H4CO2CH2C5H3N)Fe(CO)2(eta2-2-SC5H4N) (8), but also gave the unexpected 2-toluoyloxovinyl-6-toluoyloxomethylpyridine-containing complex (2-p-MeC6H4CO2C2H-6-p-MeC6H4CO2CH2C5H3N)Fe(CO)2(eta2-2-SC5H4N) (9). While the possible pathways for the novel reactions leading to complexes 1, 2, and 7-9 are suggested, the structures of complexes B, 1-4, and 6-9 were unambiguously confirmed by X-ray crystallography. In addition, model complexes A and B have been found to be catalysts for proton reduction to H2 from TFA under CV conditions.

PMID- 29189002 TI - Discovery of Novel Potent VEGFR-2 Inhibitors Exerting Significant Antiproliferative Activity against Cancer Cell Lines. AB - Computational and experimental studies were applied to the discovery of a series of novel vascular endothelial growth factor receptor 2 (VEGFR-2) inhibitors. Eight compounds exhibited nanomolar IC50 values against VEGFR-2, and compounds 6, 19, 22, and 23 showed potent antiproliferative effects against several cell lines. Particularly, compound 23 behaved better than FDA approved drugs, sorafenib and sunitinib, in antiproliferative activity against cell lines related to all nine tumor types tested (GI50 values), and it was better or comparable in safety (LC50 values). Compound 23 even demonstrated a high potency on one of the drug-resistant cell lines (NCI/ADR-RES) responsible for ovarian cancer and cell lines contributing to prostate cancer, regarded as one of the VEGF/VEGFR pathway drug-resistant tumors. This compound is likely a promising candidate for the treatment of leukemia, non-small cell lung cancer (NSCLC), colon cancer, ovarian cancer, and breast cancer with a suitable balance of both efficacy and safety. PMID- 29189003 TI - Theory of FRET "Spectroscopic Ruler" for Short Distances: Application to Polyproline. AB - Forster resonance energy transfer (FRET) is an important mechanism for the estimation of intermolecular distances, e.g., in fluorescent labeled proteins. The interpretations of FRET experiments with standard Forster theory relies on the following approximations: (i) a point-dipole approximation (PDA) for the coupling between transition densities of the chromophores, (ii) a screening of this coupling by the inverse optical dielectric constant of the medium, and (iii) the assumption of fast isotropic sampling over the mutual orientations of the chromophores. These approximations become critical, in particular, at short intermolecular distances, where the PDA and the screening model become invalid and the variation of interchromophore distances, and not just orientations, has a critical influence on the excitation energy transfer. Here, we present a quantum chemical/electrostatic/molecular dynamics (MD) method that goes beyond all of the above approximations. The Poisson-TrEsp method for the ab initio/electrostatic calculation of excitonic couplings in a dielectric medium is combined with all atom molecular dynamics (MD) simulations to calculate FRET efficiencies. The method is applied to analyze single-molecule experiments on a polyproline helix of variable length labeled with Alexa dyes. Our method provides a quantitative explanation of the overestimation of FRET efficiencies by the standard Forster theory for short interchromophore distances for this system. A detailed analysis of the different levels of approximation that connect the present Poisson TrEsp/MD method with Forster theory reveals error compensation effects, between the PDA and the neglect of correlations in interchromophore distances and orientations on one hand and the neglect of static disorder in orientations and interchromophore distances on the other. Whereas the first two approximations are found to decrease the FRET efficiency, the latter two overcompensate this decrease and are responsible for the overestimation of the FRET efficiency by Forster theory. PMID- 29189004 TI - Quantum Chemical Studies of the Structure and Stability of N-Methylated DNA Nucleobase Dimers: Insights into the Mutagenic Base Pairing of Damaged DNA. AB - DNA is constantly under attack from exogenous and endogenous sources that modify the chemical structure of the nucleobases. A common type of nucleobase damage is N-methylation, which can result in mutagenesis. Nevertheless, these lesions are often repaired by the DNA repair enzyme AlkB, albeit at varying rates. Herein we use density functional theory (B3LYP-D3(BJ)/6-311++G(2df,2p)//B3LYP/6-31G(d,p)) to comprehensively examine the structural and energetic properties of base pairs between seven nucleobase lesions resulting from N-methylation on the Watson-Crick (WC) binding face and each canonical nucleobase. By characterizing 105 stable nucleobase dimers, we provide fundamental details regarding the preferred lesion base pairings. Specifically, we reveal that the flexibility of the methylamino group resulting from methylation of an exocyclic amino substituent allows the 2MeG, 4MeC, and 6MeA lesions to maintain a preference for canonical WC base pairing, which correlates with the experimentally reported lack of mutagenicity for these damage products. In contrast, calculated distortions in key structural parameters and altered binding energies for base pairs involving adducts formed upon methylation of a ring nitrogen (namely, 1MeG, 3MeT, 1MeA, and 3MeC) help rationalize the associated mutagenicity and repair efficiencies. Most importantly, our work provides molecular-level information about the interactions between N-methylated and canonical nucleobases that is critical for future large scale modeling of damaged DNA and enzyme-DNA complexes that strive to further uncover the mutagenicity and repair propensities of these detrimental lesions. PMID- 29189006 TI - Contrasting C- and O-Atom Reactivities of Neutral Ketone and Enolate Forms of 3 Sulfonyloxyimino-2-methyl-1-phenyl-1-butanones. AB - The mechanisms of intramolecular cyclization of 3-sulfonyloxyimino-2-methyl-1 phenyl-1-butanones (1) under basic (DABCO and t-BuOK) and acidic (AcOH and TFA) conditions were investigated by means of experimental and computational methods. The ketone, enol, and enolate forms of 1 can afford different intramolecular cyclization products (2, 3, 4), depending on the conditions. The results of the reaction of 1 under basic conditions suggest intermediacy of neutral enol (DABCO) and anionic enolate (t-BuOK), while the results under acidic conditions (AcOH and TFA) indicate involvement of neutral ketones, which exhibit reactivities arising from both the oxygen lone-pair electrons (O atom reactivity) and carbon sigma electrons (C atom reactivity). The neutral enol in DABCO afforded 2H-azirine 4. On the other hand, the products (isoxazole 2 and oxazole 3) generated from the ketone form and from the enolate form are the same, but the reaction mechanisms are apparently different. The results demonstrate ambident-like reactivity of neutral ketone in the 3-sulfonyloxyimino-2-methyl-1-phenyl-1-butanone system. PMID- 29189005 TI - Phytoestrogens Weaken the Blood-Milk Barrier in Lactating Mammary Epithelial Cells by Affecting Tight Junctions and Cell Viability. AB - During lactation, mammary epithelial cells (MECs) form the blood-milk barrier by less-permeable tight junctions (TJs) to prevent the leakage of milk components. Phytoestrogens affect the proliferation, differentiation, and apoptosis of MECs. However, it remains unclear whether phytoestrogens are involved in the blood-milk barrier. Therefore, we investigated the influence of phytoestrogens (coumestrol, genistein, and daidzein) by using an in vitro mouse-MEC-culture model. The results showed that coumestrol and genistein changed the expression of TJ proteins (claudins-3 and -4 and occludin), weakened barrier function, and reduced beta-casein production. Daidzein also weakened barrier function without inhibiting beta-casein production. Additionally, coumestrol and genistein induced apoptosis in MECs. These results indicate that phytoestrogens weaken the blood milk barrier by directly affecting TJs and the cellular viability of lactating MECs in different ways.

The addition of sulfur to [(BDI)MPCy2] (M = Sn, Pb; BDI = CH{(CH3)CN-2,6 iPr2C6H3}2) results in the formation of phosphinodithioates [(BDI)MSP(S)Cy2] regardless of the conditions; however, when selenium is added to [(BDI)MPCy2], a selenium insertion product, phosphinoselenoite [(BDI)MSePCy2], can be isolated. This compound readily reacts with additional selenium to form the phosphinodiselenoate complex [(BDI)MSeP(Se)Cy2]. In contrast, the addition of selenium to [(BDI)SnP(SiMe3)2] results in the formation of the heavy ether [(BDI)SnSeSiMe3]. Differences in the solution and solid-state molecular species of tin phosphinoselenoite and phosphinodiselenoate complexes were probed using multinuclear solution and solid-state NMR spectroscopy. PMID- 29189008 TI - Pressure-Induced Polymerization of CO2 in Lithium-Carbon Dioxide Phases. AB - We report the discovery of novel CO2-based networks stabilized by Li+ cations in solid-state phases. Our exploration of the energy landscape of the Li-CO2 binary phase diagram using ab initio evolutionary structure searches revealed that in addition to the well-characterized C2O42- oxalate in Li2C2O4 viable covalent CO2 based nets emerge upon compression within the 0-100 GPa pressure range. Novel molecular units are described, such as ethene-like C2O44- in C2/m Li2(CO2), finite C4O86- chains in P1 Li3(CO2)2, one-dimensional polymeric forms based on 1,4-dioxane rings in P2/c LiCO2, and the C(O-)2 moieties in Pnma Li2CO2. This investigation shows the oxalate motif is maintained when the concentration of lithium increases from 1 to 2 in LixCO2; this interesting property may have potential in the development of renewable Li-ion batteries. Moreover, a variety of metastable phases were predicted, such as the covalent CO2-based layer in P1 Li(CO2)2.

AB - Novel carbon-carbon triple bond breaking and rearranging reactions of benzene linked allene-ynes have been established. The reactions can be selectively controlled toward the formation of two families of skeletally diverse benzo[g]indoles and 1-naphthols under mild conditions. Silver salt was found to efficiently promote indole annulation to give multifunctional benzo[g]indoles with the installation of two sulfonyl groups into the indole ring via N-S and N-F bond cleavage of NFSI, whereas NBS and NCS-mediated benzannulations occurred with the formation of dihalogenated 1-naphthols.

AB - The well-known idea of "structure determines properties" can be understood profoundly in the case of hexagonal zinc dicyanometalate. Using density functional theory (DFT) calculations, we show the uniaxial negative thermal expansion (NTE) and negative linear compressibility (NLC) properties of Zn[Au(CN)2]2. The temperature dependence of phonon frequencies within the quasi harmonic approximation (QHA) is investigated. The abnormal phonon hardening (frequency increase on heating) is detected in the ranges of 0-225, 320-345, and 410-430 cm-1, which can be indicative of the unusual physical properties of Zn[Au(CN)2]2. Due to the significance of low-energy phonon frequencies in Zn[Au(CN)2]2, in this work, the corresponding vibrational mode of the lowest frequency optical phonon at the zone center is analyzed. The specific topology of a springlike framework that will produce the effects of a compressed spring on heating and an extended spring under hydrostatic pressure is identified and leads to the coexistence of uniaxial-NTE and NLC behaviors in Zn[Au(CN)2]2. The distinguishing phonon group velocity along the a axis and c axis facilitates different responses for both the axes under temperature and hydrostatic pressure field. Through an analysis and visualization of the spatial dependence of elastic tensors, it is found that a negative Poisson's ratio (NPR) is presented in all projection planes due to the specific topology.

AB - A facile and highly diastereoselective approach toward the synthesis of potent salacinol-type alpha-glucosidase inhibitors, originally isolated from plants of the genus "Salacia", was developed using the S-alkylation of thiosugars with epoxides in HFIP (~90%, dr, alpha/beta = ~ 26/1). The dr ratio of the product was significantly improved by the protocol as compared to that of the conventional S alkylation of thiosugars (dr, alpha/beta = ~ 8/1). The protocol could be used for gram scale synthesis of the desired compounds. The 3'-O-benzylated salacinol analogs, which are the most potent in vitro inhibitors to date, were synthesized and evaluated in vivo; all analogs suppressed blood glucose levels in maltose loaded mice, at levels comparable to those of the antidiabetic agent, voglibose. PMID- 29189012 TI - Impact of Postsynthetic Surface Modification on Photoluminescence Intermittency in Formamidinium Lead Bromide Perovskite Nanocrystals. AB - We study the origin of photoluminescence (PL) intermittency in formamidinium lead bromide (FAPbBr3, FA = HC(NH2)2) nanocrystals and the impact of postsynthetic surface treatments on the PL intermittency. Single-dot spectroscopy revealed the existence of different individual nanocrystals exhibiting either a blinking (binary on-off switching) or flickering (gradual undulation) behavior of the PL intermittency. Although the PL lifetimes of blinking nanocrystals clearly correlate with the individual absorption cross sections, those of flickering nanocrystals show no correlation with the absorption cross sections. This indicates that flickering has an extrinsic origin, which is in contrast to blinking. We demonstrate that the postsynthetic surface treatment with sodium thiocyanate improves the PL quantum yields and completely suppresses the flickering, while it has no significant effect on the blinking behavior. We conclude that the blinking is caused by Auger recombination of charged excitons, and the flickering is due to a temporal drift of the exciton recombination rate induced by surface-trapped electrons.

AB - Line-shape engineering is a key strategy to endow extra stretchability to 1D silicon nanowires (SiNWs) grown with self-assembly processes. We here demonstrate a deterministic line-shape programming of in-plane SiNWs into extremely stretchable springs or arbitrary 2D patterns with the aid of indium droplets that absorb amorphous Si precursor thin film to produce ultralong c-Si NWs along programmed step edges. A reliable and faithful single run growth of c-SiNWs over turning tracks with different local curvatures has been established, while high resolution transmission electron microscopy analysis reveals a high quality monolike crystallinity in the line-shaped engineered SiNW springs. Excitingly, in situ scanning electron microscopy stretching and current-voltage characterizations also demonstrate a superelastic and robust electric transport carried by the SiNW springs even under large stretching of more than 200%. We suggest that this highly reliable line-shape programming approach holds a strong promise to extend the mature c-Si technology into the development of a new generation of high performance biofriendly and stretchable electronics.

AB - The first asymmetric convergent total synthesis of four isomers of proposed structures of cryptorigidifoliol K (1a, 1b, 1c, and 1d) has been achieved from commercially available starting materials. The key steps in this synthesis involve tandem isomerization followed by a C-O and C-C bond-forming reaction for the construction of trans-2,6-disubstituted dihydropyran, iodolactonization, isomerization of terminal alkene, and cross-metathesis reaction. The large discrepancies in the spectroscopic data (1H NMR) of synthetic cryptorigidifoliol K from the natural product suggest that the structure of the natural cryptorigidifoliol K requires revision.

The cage-like stereostructures of 1 and 2 were established by combining spectroscopic, chemical, and chiroptical methods with quantum-chemical ECD calculations. Their unique molecular frameworks may originate from "open-chain" dimers, such as 3, by an oxidation-induced cascade of reactions. They possess strong antiprotozoal properties. PMID- 29189017 TI - The dorsomedial striatum mediates Pavlovian appetitive conditioning and food consumption. AB - The dorsomedial striatum (DMS) is an important sensorimotor region mediating the acquisition of goal-directed instrumental reward learning and behavioral flexibility. However, whether the DMS also regulates Pavlovian cue-food learning is less clear. The current study used excitotoxic lesions to determine whether the DMS is critical in Pavlovian appetitive learning and behavior, using discriminative conditioning and reversal paradigms. The results showed that DMS lesions transiently retarded cue-food learning and subsequent reversal of this learning. Rats with DMS lesions selectively attenuated responding to a food cue but not a control cue, early in training, suggesting the DMS is involved when initial associations are formed. Similarly, initial reversal learning was attenuated in rats with DMS lesions, which suggests impaired flexibility to adjust behavior when the cue meaning is reversed. We also examined the effect of DMS lesions on food intake during tests with access to a highly palatable food along with standard chow diet. Rats with DMS lesions showed an altered pattern of intake, with an initial reduction in high-fat diet followed by an increase in chow consumption. These results demonstrate that the DMS has a role in mediating cue-food learning and its subsequent reversal, as well as changes in food intake when a choice is provided. Together, these results demonstrate the DMS is involved in reward associative learning and reward consumption, when behavioral flexibility is needed to adjust responding or consumption to match the current value. (PsycINFO Database Record PMID- 29189018 TI - The application of a rodent-based Morris water maze (MWM) protocol to an investigation of age-related differences in human spatial learning. AB - The current study applied a rodent-based Morris water maze (MWM) protocol to an investigation of search performance differences between young and older adult humans. To investigate whether similar age-related decline in search performance could be seen in humans based on the rodent-based protocol, we implemented a virtual MWM (vMWM) that has characteristics similar to those of the MWM used in previous studies of spatial learning in mice. Through the use of a proximity to platform measure, robust differences were found between healthy young and older adults in search performance. After dividing older adults into good and poor performers based on a median split of their corrected cumulative proximity values, the age effects in place learning were found to be largely related to search performance differences between the young and poor-performing older adults. When compared with the young, poor-performing older adults exhibited significantly higher proximity values in 83% of 24 place trials and overall in the probe trials that assessed spatial learning in the absence of the hidden platform. In contrast, good-performing older adults exhibited patterns of search performance that were comparable with that of the younger adults in most place and probe trials. Taken together, our findings suggest that the low search accuracy in poor-performing older adults stemmed from potential differences in strategy selection, differences in assumptions or expectations of task demands, as well as possible underlying functional and/or structural changes in the brain regions involved in vMWM search performance. (PsycINFO Database Record PMID- 29189019 TI - Across sex and age: Learning and memory and patterns of avian hippocampal gene expression. AB - Age-related decrements in cognitive ability have been proposed to stem from deteriorating function of the hippocampus. Many birds are long lived, especially for their relatively small body mass and elevated metabolism, making them a unique model of resilience to aging. Nevertheless, little is known about avian age-related changes in cognition and hippocampal physiology. We studied spatial cognition and hippocampal expression of the age-related gene, Apolipoprotein D (ApoD), and the immediate early gene Egr-1 in zebra finches at various developmental time points. In a first experiment, middle-aged adult males outperformed middle-aged females in learning correct food locations in a four-arm maze, but all birds remembered the task equally well after a 5- or 10-day delay. In a second experiment comparing young and old birds, aged birds showed minimal evidence for deterioration in spatial cognition or motivation relative to young birds, except that aged females showed less rapid gains in accuracy during spatial learning than young females. These findings indicate that sex differences in hippocampus-dependent spatial learning and decline with age are phylogenetically conserved. With respect to hippocampal gene expression, adult females expressed Egr-1 at significantly greater levels than males after memory retrieval, perhaps reflecting a neurobiological compensation. Contrary to mammals, ApoD expression was elevated in young zebra finches compared with aged birds. This may explain the near absence of decrements in spatial memory due to age, possibly indicating an alternative mechanism of managing oxidative stress in aged birds. (PsycINFO Database Record PMID- 29189020 TI - Effect of social isolation on anxiety-related behaviors, cortisol, and monoamines in adult zebrafish. AB - Social isolation can be used to study behavioral, neural, and hormonal mechanisms that regulate interactions in social animals. Although isolation effects have been reported in social mammals and various fish species, systematic studies with isolated zebrafish are rare. Here, the authors examined behavior (social and nonsocial), physiological stress (whole-body cortisol levels), and neurochemicals (serotonin, dopamine, and their metabolites), following acute and chronic social isolation in adult zebrafish. To observe how isolated fish respond behaviorally to social stimuli, they exposed zebrafish to live conspecifics or animated images after acute (24 hr) or chronic (6 months) social isolation. The authors observed that isolation did not affect locomotor activity, but acute isolation had weak nonsignificant anxiogenic effects in adult zebrafish. They also found that all isolated fish responded to both live and animated social stimuli, and the stress hormone, cortisol was lower in chronically isolated fish. Finally, neurochemical analyses showed that serotonin levels increased when fish were exposed to social stimulus after acute isolation, but its metabolite 5HIAA decreased in response to social stimulus following both acute and chronic isolation. Levels of both dopamine and its metabolite DOPAC were also reduced in fish exposed to social stimulus after acute and chronic isolation. Overall, these results show that isolation in zebrafish is an effective tool to study fundamental mechanisms controlling social interaction at behavioral and physiological levels.

AB - Ecological momentary assessment was used to examine immediate changes in 87 college students' smoking-related attitudes, beliefs, and intentions as a joint function of their exposure to antismoking media and smoking status. Students (37 never smokers, 41 experimental smokers, and 9 current intermittent smokers) carried handheld data-collection devices for 3 weeks to record naturally occurring exposures to antismoking media and respond to investigator-initiated control prompts. At each reported exposure to antismoking media and each control prompt, participants reported their smoking-related attitudes, perceptions of the prevalence of smoking among their peers, resistance self-efficacy, and intentions to smoke. Mixed-effects regression was used to compare responses between encounters with antismoking media and control prompts. Experimental smokers reported weaker intentions to smoke and greater resistance self-efficacy at moments of exposure to antismoking media than at control prompts. Regardless of smoking experience, participants reported higher perceived prevalence of smoking at times of exposure to antismoking media than at control prompts. These findings generally support the value of antismoking media messages for shifting the beliefs and intentions of experimental smokers, who are at high risk for becoming committed regular smokers. (PsycINFO Database Record PMID- 29189022 TI - Using counterattitudinal advocacy to change drinking: A pilot study. AB - The persistence of risky drinking among young adults in college calls for continued efforts to prevent alcohol-related harms. This study tested a novel prevention strategy targeting a specific mechanism of change: creating attitude behavior dissonance. Informed by an extensive literature showing strong and consistent associations between alcohol attitudes and drinking behavior, we adapted a brief counterattitudinal advocacy (CAA) manipulation to the alcohol prevention context. We conducted a small randomized controlled trial with 49 heavy-drinking students who reported drinking 4/5 drinks in 1 sitting (female/male, respectively) and endorsed >=2 alcohol-related consequences in the previous month. Participants were randomly assigned to 1 of 2 conditions (CAA or control). We examined the number of words written in response to the prompts, evaluated adherence to the core theoretical principles used in CAA, and calculated between- and within-group effect sizes on preliminary outcomes (drinking intentions and alcohol consumption). We found that participants in the CAA condition wrote more, and the experience was perceived as consistent with CAA theory. The between-group effect sizes on drinking intentions and drinks per week were d = .36 and d = .27, respectively, and the within-group effect size for drinks per week was d = .83 for those in the CAA condition. Overall, the results of this pilot study support the feasibility and acceptability of CAA-based alcohol use interventions. This study represents a promising first step in adapting CAA-based interventions for use in the alcohol use domain.

We adapted a verbal memory test to evaluate long-term memory consolidation in healthy volunteers. METHOD: A sample of 238 participants (M = 42.23 years old, SD = 16.45) was administered an adapted version of the French RL/RI-16 (Van der Linden & the members of GREMEM, 2004), the One-Week Free and Cued Selective Reminding Test-word version, in which special feature relies on a 30-min and a 1-week-delayed recall after encoding. We proposed normative data on 4 indicators, depending on participants' own performance during the test, to measure their encoding, storage and consolidation abilities, with a method using an ascendant step-by-step linear regression model and a percentile procedure. RESULTS: Results showed a better performance in women than in men for encoding and cueing scores (p < .01 and p < .05, respectively). We also highlighted an increase of the forgetting score according to the recall delay after encoding (30 min vs. 7 days; Z = 12.49, p < .001), the forgetting percentage 7 days after encoding being largely influenced by participants' age and gender (F[2, 236] = 248.1, p < .001; adjusted R2 = 67%). CONCLUSIONS: This study emphasized the role of demographic factors on long-term memory consolidation. The demographically adjusted normative data we provide for the One Week Free and Cued Selective Reminding Test-word version make it a sensitive tool for long-term memory consolidation assessment in clinical and forensic practice.

AB - Parental cannabis use disorder (CUD) and low positive parenting (monitoring, support, and consistency) are risk factors for adolescent cannabis use. However, it is unclear whether parental cannabis use without CUD is sufficient to increase risk for low positive parenting and adolescent cannabis use. Additionally, parents may not treat each of their adolescents the same, and risk for adolescent cannabis use may increase as a result of low levels of positive parenting in families or low positive parenting unique to each adolescent. The current study prospectively tested low positive parenting as a mediator of the relation between parental cannabis use history (with parental cannabis use and CUD considered separately) and adolescent cannabis use at the family level and individual level. Participants were 363 adolescents from a multigenerational longitudinal study who reported on positive parenting when they were ages 9-16 (M = 11.6, SD = 1.40) and on cannabis use when they were ages 13-19 (M = 16.3, SD = 1.84). Parents reported on their own cannabis use and CUD. Results showed that parental CUD was associated with adolescent cannabis use (OR = 3.62, p = .047) but parental cannabis use without CUD was not, and only parental CUD predicted low positive parenting (B = -0.28, p < .05). Average levels of low positive parenting within a family partially mediated the association between parental CUD and offspring cannabis use. These findings suggest parental cannabis use alone may not impair parenting, but parental use that meets criteria for CUD does impair parenting. Additionally, average levels of positive parenting in families may be a mechanism underlying the intergenerational transmission of cannabis use. (PsycINFO Database Record PMID- 29189025 TI - The Interplay of Personality and Functional Health in Old and Very Old Age: Dynamic Within-Person Interrelations Across up to 13 Years. AB - Conceptual and empirical work has long suggested that personality and health are closely intertwined later in life. Little is known, however, about the nature and direction of time-ordered associations between the 2 domains within-persons. We applied continuous time auto- and cross-effects models to up to 6 waves of 13 year longitudinal data from the Berlin Aging Study (N = 516, M = 84.92, SD = 8.66, age range 70 to 103) and examined time-ordered relations between personality traits (i.e., extraversion and neuroticism) and performance-based indicators of functional health (i.e., physical and sensory functioning) in late life. Consistent with proposals to distinguish the young-old (age 70 to 84) from the oldest-old (aged 85+) in later life, results suggest that predictive effects of neuroticism on functional health are stronger in younger as compared with older individuals. In contrast, health decrements precede and predict change in neuroticism in the oldest-old more strongly as compared with the young-old. In addition, we found that decreases in extraversion predict subsequent decreases in functional health and vice versa, with effects being equally pronounced among younger and older participants. Furthermore, by employing continuous time models we could demonstrate that the magnitude of these effects varies depending upon the time interval under consideration. These findings suggest that personality and functional health are closely intertwined in old and very old age, and that the nature of time-ordered associations differs between traits and age period. We discuss conceptual and practical implications. (PsycINFO Database Record PMID- 29189027 TI - Goal versus trait explanations: Causal attributions beyond the trait-situation dichotomy. AB - In 4 studies, we show that two behavioral dimensions specified in Kelley's (1967) model of attribution, consistency and distinctiveness of behaviors, determine perceivers' likelihood to explain others' behaviors in terms of their goals versus traits. Participants tended to attribute the cause of others' behaviors to their goals (vs. traits and other characteristics) when behaviors were characterized by high distinctiveness (Study 1A & 1B) or low consistency (Study 2). On the other hand, traits were ascribed as predominant causal explanations when behaviors had low distinctiveness or high consistency. Study 3 investigated the combined effect of those behavioral dimensions on causal attributions and showed that behaviors with high distinctiveness and consistency as well as low distinctiveness and consistency trigger goal attributions. We discuss the implications of the present research in terms of going beyond the dominant approach of trait-situation dichotomy in attribution research. (PsycINFO Database Record PMID- 29189026 TI - The ebbs and flows of attachment: Within-person variation in attachment undermine secure individuals' relationship wellbeing across time. AB - Although attachment security is relatively stable over time, individuals do experience significant within-person variation in their attachment security across time. No research to date, however, has assessed the relational consequences of within-person variation (fluctuations) in attachment security toward a specific attachment figure. Study 1 (N = 409) first examined whether attachment security was associated with individuals' expectations that their current intimate relationship would be stable and consistent over time (vs. inconsistent and unstable). Studies 2 and 3 extended this by examining the prevalence and consequences of actual within-person variation (fluctuations) in relationship-specific attachment security toward an intimate partner in 2 multiwave longitudinal studies that assessed individuals (Study 2, N = 324) and couples (Study 3, N = 171 dyads). The results indicate that secure individuals (those low in attachment anxiety or attachment avoidance) expect their current relationship to remain relatively stable and consistent over time (Study 1). However, Studies 2 and 3 demonstrated that most individuals do experience fluctuations in their relationship-specific attachment security. Moreover, greater fluctuations predict declines in relationship satisfaction (Studies 2 and 3) and increases in relationship distress (Study 3) over time, but primarily for secure individuals (those low in baseline attachment anxiety or attachment avoidance). This set of findings highlight the importance of examining within person fluctuations in attachment security, which are associated with declines in trajectories of relationship wellbeing, particularly for secure individuals who anticipate greater stability in their relationships. (PsycINFO Database Record PMID- 29189028 TI - Introduction to the special section on sexual and gender minority health. AB - The field of sexual and gender minority health has advanced exponentially in the past decade. The Journal of Consulting and Clinical Psychology (JCCP) has made important strides in publishing work on sexual and gender minority health. Although the following set of articles was not originally planned as a special section, most of the articles address, in some way, sexual and gender minority specific stressors such as perceived or overt stigma and/or the higher risk for emotional and substance use problems facing this population. Together, the papers in this section are models of some of the best work being conducted on sexual and gender minority health. Not only do they address significant problems, they do so in large, nonoverlapping samples, using novel and strong methodologies. (PsycINFO Database Record PMID- 29189030 TI - A weekly diary study of minority stress, coping, and internalizing symptoms among gay men. AB - OBJECTIVE: Research has demonstrated that gay men are at increased risk for internalizing disorders compared with heterosexual men and that minority stressors are risk factors. However, the mechanisms underlying the associations between minority stressors and internalizing symptoms remain unclear. The current study examined coping strategies (active and disengaged coping) as mediators of the associations between minority stressors (internalized homonegativity [IH] and rejection sensitivity [RS]) and internalizing symptoms. METHOD: A sample of 147 gay men completed a baseline questionnaire and weekly questionnaires for seven consecutive weeks. RESULTS: At the between-person level, higher IH and RS were associated with higher disengaged coping, but not active coping. In turn, higher disengaged coping was associated with higher internalizing symptoms. Disengaged coping mediated the between-person association between IH and internalizing symptoms. At the within-person level, higher IH and RS were associated with higher disengaged coping, which, in turn, was associated with higher internalizing symptoms. Higher RS was also associated with higher active coping. Disengaged coping mediated the within-person associations between both minority stressors and internalizing symptoms. Of note, some associations with IH became nonsignificant controlling for RS, suggesting that the latter has a stronger influence on coping and internalizing symptoms. CONCLUSIONS: Findings demonstrate that gay men's negative thoughts and feelings about their sexual orientation and anxious expectations of rejection vary from week to week and this weekly fluctuation has an impact on mental health. Further, findings implicate disengaged coping as a mechanism through which minority stressors influence internalizing symptoms. (PsycINFO Database Record PMID- 29189029 TI - Ecological momentary assessment of daily discrimination experiences and nicotine, alcohol, and drug use among sexual and gender minority individuals. AB - OBJECTIVE: Sexual and gender minority (SGM) individuals experience elevated rates of minority stress, which has been linked to higher rates of nicotine and substance use. Research on this disparity to date is largely predicated on methodology that is insensitive to within day SGM-based discrimination experiences, or their relation to momentary nicotine and substance use risk. We address this knowledge gap in the current study using ecological momentary assessment (EMA). METHOD: Fifty SGM individuals, between 18 and 45 years of age, were recruited from an inland northwestern university, regardless of their nicotine or substance use history, and invited to participate in an EMA study. Each were prompted to provide data, six times daily (between 10:00 a.m. and 10:00 p.m.) for 14 days, regarding SGM-based discrimination, other forms of mistreatment, and nicotine, drug, and alcohol use since their last prompt. RESULTS: Discrimination experiences that occurred since individuals' last measurement prompt were associated with greater odds of nicotine and substance use during the same measurement window. Substance use was also more likely to occur in relation to discrimination reported two measurements prior in lagged models. Relative to other forms of mistreatment, discrimination effects were consistently larger in magnitude and became stronger throughout the day/evening. CONCLUSION: This study adds to existing minority stress research by highlighting the both immediate and delayed correlates of daily SGM-based discrimination experiences. These results also contribute to our understanding of daily stress processes and provide insight into ways we might mitigate these effects using real-time monitoring and intervention technology. (PsycINFO Database Record PMID- 29189031 TI - "Memory support strategies and bundles: A pathway to improving cognitive therapy for depression?": Correction to Dong, Lee, and Harvey (2017). AB - : Reports an error in "Memory support strategies and bundles: A pathway to improving cognitive therapy for depression" by Lu Dong, Jason Y. Lee and Allison G. Harvey (Journal of Consulting and Clinical Psychology, 2017[Mar], Vol 85[3], 187-199). In the article, there was an error in Table 2 of the Results. In Table 2, the MS summary scores of the Total amount of MS are missing six descriptive statistics. They should have read as: 13.50, 8.54, 23, 18.32, 8.83, 23. The corrected table is included. (The following abstract of the original article appeared in record 2017-07144-001.) Objective: Therapist use of memory support (MS) alongside treatment-as-usual, with the goal of enhancing patient recall of treatment contents, has been of recent interest as a novel pathway to improve treatment outcome. The memory support intervention (MSI) involves treatment providers' using 8 specific MS strategies to promote patient memory for treatment. The present study examines to what extent therapist use of MS strategies and bundles improves patient recall of treatment contents and treatment outcome. METHOD: The data were drawn from a pilot RCT reported elsewhere. Participants were 48 adults (mean age = 44.27 years, 29 females) with major depressive disorder (MDD), randomized to receive 14 sessions of either CT + Memory Support (n = 25) or CT-as-usual (n = 23). Therapist use of MS was coded using the Memory Support Rating Scale. Patient memory and treatment outcomes were assessed at baseline, midtreatment (patient recall only), posttreatment, and 6 month follow-up. RESULTS: Participants in CT + Memory Support received significantly higher amount of MS relative to CT-as-usual. Although not reaching statistical significance, small-to-medium effects were observed between MS strategies and patient recall in the expected direction. Although MS variables were not significantly associated with changes in continuous depressive symptoms, MS was associated with better global functioning. MS also exhibited small to medium effects on treatment response and recurrence in the expected direction but not on remission, though these effects did not reach statistical significance. CONCLUSIONS: These results provide initial empirical evidence supporting an active method for therapists to implement MS strategies. (PsycINFO Database Record PMID- 29189033 TI - Comparing treatment response between LGBQ and heterosexual individuals attending a CBT- and DBT-skills-based partial hospital. AB - OBJECTIVE: Despite a greater need for mental health treatment in individuals identifying as lesbian, gay, bisexual, queer, and other sexual minority identities (LGBQ+), no prior study has examined mental health treatment outcomes for LGBQ+ populations receiving standard care. We compared individuals identifying as LGBQ+ or heterosexual on treatment outcomes following a partial hospital program based on cognitive behavioral therapy (CBT) and dialectical behavior therapy (DBT). METHOD: A total of 441 participants (19% LGBQ+; mean age = 34.42 years; 56% female, 42% male, 2% nonbinary) attending a partial hospital program completed measures at admission and discharge as part of standard care. We compared LGBQ+ and heterosexual individuals on symptom outcomes (24-item Behavior and Symptom Identification Scale, 7-item Generalized Anxiety Disorder Scale, 9-item Patient Health Questionnaire), program dropout due to inpatient hospitalization, clinical global improvement, and perceived quality of care, controlling for baseline characteristics using propensity score adjustment. RESULTS: Controlling for baseline demographic and clinical variables and a 10% false discovery rate, LGBQ+ and heterosexual individuals did not differ on treatment outcomes. However, when examining sexual identity subgroups, bisexual individuals reported more self-injurious and suicidal thoughts and worse perceptions of care at posttreatment compared to all other sexual identities. CONCLUSIONS: Findings support the comparable effectiveness of CBT- and DBT-skills based hospital treatment for LGBQ+ and heterosexual individuals overall but suggest specific treatment disparities for bisexual individuals. Future research is needed to establish the effectiveness of traditional evidence-based treatment in other settings and to determine whether LGBQ+ affirmative treatments for specific LGBQ+ subgroups are superior to traditional treatments. (PsycINFO Database Record PMID- 29189034 TI - Unique effects of setting goals on behavior change: Systematic review and meta analysis. AB - OBJECTIVE: Goal setting is a common feature of behavior change interventions, but it is unclear when goal setting is optimally effective. The aims of this systematic review and meta-analysis were to evaluate: (a) the unique effects of goal setting on behavior change, and (b) under what circumstances and for whom goal setting works best. METHOD: Four databases were searched for articles that assessed the unique effects of goal setting on behavior change using randomized controlled trials. One-hundred and 41 papers were identified from which 384 effect sizes (N = 16,523) were extracted and analyzed. A moderator analysis of sample characteristics, intervention characteristics, inclusion of other behavior change techniques, study design and delivery, quality of study, outcome measures, and behavior targeted was conducted. RESULTS: A random effects model indicated a small positive unique effect of goal setting across a range of behaviors, d = .34 (CI [.28, .41]). Moderator analyses indicated that goal setting was particularly effective if the goal was: (a) difficult, (b) set publicly, and (c) was a group goal. There was weaker evidence that goal setting was more effective when paired with external monitoring of the behavior/outcome by others without feedback and delivered face-to-face. CONCLUSIONS: Goal setting is an effective behavior change technique that has the potential to be considered a fundamental component of successful interventions. The present review adds novel insights into the means by which goal setting might be augmented to maximize behavior change and sets the agenda for future programs of research. (PsycINFO Database Record PMID- 29189032 TI - Applying network analysis to psychological comorbidity and health behavior: Depression, PTSD, and sexual risk in sexual minority men with trauma histories. AB - OBJECTIVE: High rates of depression and posttraumatic stress disorder (PTSD) contribute to sexual risk, particularly in men who have sex with men (MSM) who have experienced childhood sexual abuse. The comorbidity between depression and PTSD and mechanisms by which they contribute to sexual risk in MSM remain unclear. This study sought to demonstrate the feasibility and utility of a network approach to (a) characterize symptom interconnections between depression and PTSD in MSM, (b) identify specific symptoms related to sexual risk behavior, and (c) compare symptom networks across groups at different levels of risk. METHOD: Cross-sectional baseline data were collected from 296 HIV-negative urban MSM as part of a multisite randomized intervention trial. Symptoms of depression and PTSD were self-reported along with sexual risk behavior. Analyses were performed in R using regularized partial correlation network modeling. RESULTS: Network analyses revealed complex associations between depression and PTSD symptoms and in relation to sexual risk behavior. While symptoms clustered within their respective disorders, depression and PTSD were connected at key symptom nodes (e.g., sleep, concentration). Specific symptoms (e.g., avoiding thoughts and feelings) were linked to sexual risk behavior. Network comparisons across risk groups suggested avoidant processes could be more readily activated in higher-risk individuals, whereas hyperarousal symptoms may be more salient and protective for lower-risk individuals. CONCLUSIONS: This study is one of the earliest network analyses of depression and PTSD, and first to extend this inquiry to health behavior. Symptom-level investigations may clarify mechanisms underlying psychological comorbidity and behavioral risk in MSM and refine targets for intervention/prevention. (PsycINFO Database Record PMID- 29189036 TI - Identity-specific motivation: How distinct identities direct self-regulation across distinct situations. AB - Research on self-regulation has traditionally emphasized that people's thoughts and actions are guided by either (a) domain-general motivations that emerge from a cumulative history of life experiences, or (b) situation-specific motivations that emerge in immediate response to the incentives present in a particular context. However, more recent studies have illustrated the importance of understanding the interplay between such domain-general and situation-specific motivations across the types of contexts people regularly encounter. The present research, therefore, expands existing perspectives on self-regulation by investigating how people's identities-the internalized roles, relationships, and social group memberships that define who they are-systemically guide when and how different domain-general motivations are activated within specific types of situations. Using the motivational framework described by regulatory focus theory (Higgins, 1997), Studies 1 and 2 demonstrate that people indeed have distinct, identity-specific motivations that uniquely influence their current self regulation when such identities are active. Studies 3-5 then begin to explore how identity-specific motivations are situated within people's larger self-concept. Studies 3a and 3b demonstrate that the less compatible people's specific identities, the more distinct are the motivations connected to those identities. Studies 4-5 then provide some initial, suggestive evidence that identity-specific motivations are not a separate, superordinate feature of people's identities that then alter how they pursue any subordinate, identity-relevant traits, but instead that such motivations emerge from the cumulative motivational significance of the subordinate traits to which the identities themselves become attached. Implications for understanding the role of the self-concept in self-regulation are discussed. (PsycINFO Database Record PMID- 29189035 TI - Processes of change after a sudden gain and relation to treatment outcome Evidence for an upward spiral. AB - OBJECTIVE: Sudden gains are sudden symptom improvements from 1 psychotherapy session to the next. This study investigates the processes that may facilitate treatment outcome after a sudden gain occurred. METHOD: A sample of 211 depressed patients who underwent cognitive-behavioral therapy was analyzed. Sudden gains were identified using a session-by-session self-report symptom measure. Patient ratings of general change factors (therapeutic alliance; coping skills) in the sessions before and after a sudden gain were investigated as predictors of outcome. Propensity score matching was used to compare sudden gain patients with similar patients who did not experience a sudden gain. RESULTS: Therapeutic alliance and coping skills increased in the postgain sessions. There were no comparable processes of change among patients without sudden gains. The therapeutic alliance was found to moderate the association between sudden gains and treatment outcome. CONCLUSION: Results suggest that sudden gains trigger change factors that facilitate the association between gains and treatment outcome. Patient-therapist dyads should work with sudden gains to consolidate symptom relief. (PsycINFO Database Record PMID- 29189037 TI - Home alone: Why people believe others' social lives are richer than their own. AB - Although decades of research show that people tend to see themselves in the best possible light, we present evidence that people have a surprisingly grim outlook on their social lives. In 11 studies (N = 3,293; including 3 preregistered), we find that most people think that others lead richer and more active social lives than they do themselves. We show that this bias holds across multiple populations (college students, MTurk respondents, shoppers at a local mall, and participants from a large, income-stratified online panel), correlates strongly with well being, and is particularly acute for social activities (e.g., the number of parties one attends or proximity to the "inner circle" of one's social sphere). We argue that this pessimistic bias stems from the fact that trendsetters and socialites come most easily to mind as a standard of comparison and show that reducing the availability of extremely social people eliminates this bias. We conclude by discussing implications for research on social comparison and self enhancement. (PsycINFO Database Record PMID- 29189038 TI - Effect of personality on oral health-related quality of life in undergraduates. AB - OBJECTIVES: To evaluate the effects of personality traits and other variables on oral health-related quality of life (OHRQoL) of Chinese undergraduates aged 17 to 24 years with no history of orthodontic treatment. MATERIALS AND METHODS: A total of 443 undergraduate students aged 17 to 24 years were selected and completed a two-section questionnaire: the Eysenck Personality Questionnaire Short Scale Chinese version and the Oral Health Impact Profile-14 Chinese version (OHIP-14). Malocclusion severity was assessed via clinical examination using the dental health component (DHC) and esthetic component of the Index of Orthodontic Treatment Need (IOTN). Severe dentofacial deformities that required orthognathic surgery were excluded. RESULTS: The total and all dichotomized OHIP-14 dimensions correlated closely with the neuroticism personality traits ( P < .001). The total and some subscales of OHIP-14 were related with psychoticism. Women had higher OHIP-14 scores than men, especially in the normal occlusion group. Nevertheless, men with more severe malocclusions had higher scores that were similar to those of women. OHRQoL was significantly different between the major of dentistry and other majors. CONCLUSIONS: Personality affects comprehensive OHRQoL, and the most significant predictor is neuroticism. Female young adults have worse OHRQoL than male young adults, especially among those with mild malocclusion. PMID- 29189039 TI - Reliability of three-dimensional anterior cranial base superimposition methods for assessment of overall hard tissue changes: A systematic review. AB - OBJECTIVE: The purpose of this systematic review was to synthesize the available literature concerning the reliability of three-dimensional superimposition methods when assessing changes in craniofacial hard tissues. MATERIALS AND METHODS: Four electronic databases were searched. Two authors independently reviewed potentially relevant articles for eligibility. Clinical trials, cohort, case-control, and cross-sectional studies that evaluated the reliability of three dimensional superimposition methods on the anterior cranial base were included. RESULTS: Six studies fulfilled the inclusion criteria. Four studies used the voxel-based registration method, one used the landmark-based method and one used the surface-based method. Regarding reliability, the voxel-based studies showed on average a difference of 0.5 mm or less between images. The optimized analysis using a six-point correction algorithm in the landmark-based method showed 1.24 mm magnitude of error between images. CONCLUSIONS: Although reliability appears to be adequate, the small sample size and high risk of bias among studies make available evidence still insufficient to draw strong conclusions. PMID- 29189040 TI - Organic Haze as a Biosignature in Anoxic Earth-like Atmospheres. AB - Early Earth may have hosted a biologically mediated global organic haze during the Archean eon (3.8-2.5 billion years ago). This haze would have significantly impacted multiple aspects of our planet, including its potential for habitability and its spectral appearance. Here, we model worlds with Archean-like levels of carbon dioxide orbiting the ancient Sun and an M4V dwarf (GJ 876) and show that organic haze formation requires methane fluxes consistent with estimated Earth like biological production rates. On planets with high fluxes of biogenic organic sulfur gases (CS2, OCS, CH3SH, and CH3SCH3), photochemistry involving these gases can drive haze formation at lower CH4/CO2 ratios than methane photochemistry alone. For a planet orbiting the Sun, at 30* the modern organic sulfur gas flux, haze forms at a CH4/CO2 ratio 20% lower than at 1* the modern organic sulfur flux. For a planet orbiting the M4V star, the impact of organic sulfur gases is more pronounced: at 1* the modern Earth organic sulfur flux, a substantial haze forms at CH4/CO2 ~ 0.2, but at 30* the organic sulfur flux, the CH4/CO2 ratio needed to form haze decreases by a full order of magnitude. Detection of haze at an anomalously low CH4/CO2 ratio could suggest the influence of these biogenic sulfur gases and therefore imply biological activity on an exoplanet. When these organic sulfur gases are not readily detectable in the spectrum of an Earth-like exoplanet, the thick organic haze they can help produce creates a very strong absorption feature at UV-blue wavelengths detectable in reflected light at a spectral resolution as low as 10. In direct imaging, constraining CH4 and CO2 concentrations will require higher spectral resolution, and R > 170 is needed to accurately resolve the structure of the CO2 feature at 1.57 MUm, likely the most accessible CO2 feature on an Archean-like exoplanet.

AB - AIM: To analyze clinical significance of preoperative liver stiffness measurement (LSM) by FibroScan in postcurative resection hepatitis B virus (HBV) related hepatocellular carcinoma (HCC). PATIENTS & METHODS: A total of 263 patients underwent preoperative LSM and curative operation for primary HBV-positive HCC were enrolled. The correlation between preoperative LSM and survival was analyzed. RESULTS: All patients were stratified into two groups using the optimal cut-off value (13.2 kPa) of LSM using the receiver-operating characteristic. Patients with an LSM >=13.2 kPa had poorer overall survival (median, 61.3 vs 48.2 months, hazard ratio: 0.15; p = 0.009) and recurrence-free survival (median, 60.4 vs 47.0 months; hazard ratio: 0.32; p = 0.011) than patients with an LSM <13.2 kPa and LSM also have been confirmed as independent predictor for survival for HCC. DISCUSSION: This could potentially guide patient stratification and individualized treatment. CONCLUSION: Preoperative LSM can be considered as an independent prognostic factor for HBV-positive HCC after curative resection. PMID- 29189042 TI - Characterizing indeterminate (Likert-score 3/5) peripheral zone prostate lesions with PSA density, PI-RADS scoring and qualitative descriptors on multiparametric MRI. AB - OBJECTIVE: To determine whether indeterminate (Likert-score 3/5) peripheral zone (PZ) multiparametric MRI (mpMRI) studies are classifiable by prostate-specific antigen (PSA), PSA density (PSAD), Prostate Imaging Reporting And Data System version 2 (PI-RADS_v2) rescoring and morphological MRI features. METHODS: Men with maximum Likert-score 3/5 within their PZ were retrospectively selected from 330 patients who prospectively underwent prostate mpMRI (3 T) without an endorectal coil, followed by 20-zone transperineal template prostate mapping biopsies +/- focal lesion-targeted biopsy. PSAD was calculated using pre-biopsy PSA and MRI-derived volume. Two readers A and B independently assessed included men with both Likert-assessment and PI-RADS_v2. Both readers then classified mpMRI morphological features in consensus. Men were divided into two groups: significant cancer (>= Gleason 3 + 4) or insignificant cancer (<= Gleason 3 + 3)/no cancer. Comparisons between groups were made separately for PSA & PSAD using Mann-Whitney test and morphological descriptors with Fisher's exact test. PI-RADS_v2 and Likert-assessment were descriptively compared and percentage inter reader agreement calculated. RESULTS: 76 males were eligible for PSA & PSAD analyses, 71 for PI-RADS scoring, and 67 for morphological assessment (excluding significant image artefacts). Unlike PSA (p = 0.915), PSAD was statistically different (p = 0.004) between the significant [median: 0.19 ng ml-2 (interquartile range: 0.13-0.29)] and non-significant/no cancer [median: 0.13 ng ml-2 (interquartile range: 0.10-0.17)] groups. Presence of mpMRI morphological features was not significantly different between groups. Subjective Likert assessment discriminated patients with significant cancer better than PI-RADS_v2. Inter-reader percentage agreement was 83% for subjective Likert-assessment and 56% for PI-RADS_v2. CONCLUSION: PSAD may categorize presence of significant cancer in patients with Likert-scored 3/5 PZ mpMRI findings. Advances in knowledge: PSAD may be used in indeterminate PZ mpMRI to guide decisions between biopsy vs monitoring. PMID- 29189043 TI - An Antarctic Extreme Halophile and Its Polyextremophilic Enzyme: Effects of Perchlorate Salts. AB - Effects of perchlorate salts prevalent on the surface of Mars are of significant interest to astrobiology from the perspective of potential life on the Red Planet. Halorubrum lacusprofundi, a cold-adapted halophilic Antarctic archaeon, was able to grow anaerobically on 0.04 M concentration of perchlorate. With increasing concentrations of perchlorate, growth was inhibited, with half-maximal growth rate in ca. 0.3 M NaClO4 and 0.1 M Mg(ClO4)2 under aerobic conditions. Magnesium ions were also inhibitory for growth, but at considerably higher concentrations, with half-maximal growth rate above 1 M. For a purified halophilic beta-galactosidase enzyme of H. lacusprofundi expressed in Halobacterium sp. NRC-1, 50% inhibition of catalytic activity was observed at 0.88 M NaClO4 and 0.13 M Mg(ClO4)2. Magnesium ions were a more potent inhibitor of the enzyme than of cell growth. Steady-state kinetic analysis showed that Mg(ClO4)2 acts as a mixed inhibitor (KI = 0.04 M), with magnesium alone being a competitive inhibitor (KI = 0.3 M) and perchlorate alone acting as a very weak noncompetitive inhibitor (KI = 2 M). Based on the estimated concentrations of perchlorate salts on the surface of Mars, our results show that neither sodium nor magnesium perchlorates would significantly inhibit growth and enzyme activity of halophiles. This is the first study of perchlorate effects on a purified enzyme. Key Words: Halophilic archaea-Perchlorate-Enzyme inhibition-Magnesium. Astrobiology 18, 412-418.

AB - OBJECTIVES: To evaluate the short-term efficacy and safety of desvenlafaxine (25 50 mg/d) compared with placebo in children and adolescents with major depressive disorder (MDD). METHODS: Outpatient children (7-11 years) and adolescents (12-17 years) who met DSM-IV-TR criteria for MDD and had screening and baseline Children's Depression Rating Scale-Revised (CDRS-R) total scores >40 were randomly assigned to 8-week treatment with placebo, desvenlafaxine (25, 35, or 50 mg/d based on baseline weight), or fluoxetine (20 mg/d). The primary efficacy endpoint was change from baseline in CDRS-R total score at week 8, analyzed using a mixed-effects model for repeated measures. Secondary efficacy endpoints included week 8 Clinical Global Impressions-Severity, Clinical Global Impressions Improvement (CGI-I), and response (CGI-I <= 2). Safety assessments included adverse events, physical and vital sign measurements, laboratory evaluations, electrocardiogram, and the Columbia-Suicide Severity Rating Scale. RESULTS: The safety population included 339 patients (children, n = 130; adolescents, n = 209). The primary endpoint, change from baseline in CDRS-R total score at week 8, did not statistically separate from placebo, for either desvenlafaxine (adjusted mean [standard error] change, -22.6 [1.17]) or fluoxetine (-24.8 [1.17]; placebo, -23.1 [1.18]). Week 8 CGI-I response rates were significantly greater for fluoxetine (78.2%; p = 0.017) than for placebo (62.6%); desvenlafaxine (68.7%) did not differ from placebo. Other secondary outcomes were consistent with those obtained with CDRS-R. Rates of treatment-emergent adverse events were comparable among treatment groups (desvenlafaxine, 60.0%; placebo, 70.5%; and fluoxetine, 64.3%). CONCLUSION: Desvenlafaxine did not demonstrate efficacy for treating MDD in children and adolescents in this trial. Because neither desvenlafaxine nor the reference medication, fluoxetine, demonstrated a statistically significant difference from placebo on the primary endpoint, this was considered a failed trial and no efficacy conclusions can be drawn. Desvenlafaxine 25-50 mg/d was generally safe and well tolerated in children and adolescents in this study. PMID- 29189045 TI - The effects of Baduanjin exercise on fatigue and quality of life in patients with heart failure: A randomized controlled trial. AB - AIMS: The purpose of this study was to examine the effects of Baduanjin exercise on fatigue and quality of life in patients with heart failure. METHODS: The study was a randomized controlled trial. Participants diagnosed with heart failure were recruited from two large medical centers in northern Taiwan. Participants were randomly assigned to the intervention ( n=39) or control ( n=41) groups. Patients in the intervention group underwent a 12-week Baduanjin exercise program, which included Baduanjin exercise three times per week for 12 weeks at home, a 35 minute Baduanjin exercise demonstration video, a picture-based educational brochure, and a performance record form. The control group received usual care and received no intervention. Fatigue and quality of life were assessed using a structural questionnaire at baseline, four weeks, eight weeks, and 12 weeks after the intervention. RESULTS: Participants in the Baduanjin exercise group showed significant improvement in fatigue ( F=5.08, p=0.009) and quality of life ( F=9.11, p=0.001) over time from baseline to week 12 after the intervention. Those in the control group showed significantly worse fatigue ( F=3.46, p=0.033) over time from baseline to week 12 and no significant changes in quality of life ( F=0.70, p=0.518). Compared to the control group, the exercise group demonstrated significantly greater improvement in fatigue and quality of life at four weeks, eight weeks, and 12 weeks. CONCLUSIONS: This simple traditional exercise is recommended for Taiwanese patients with heart failure in order to improve their fatigue and quality of life. PMID- 29189046 TI - The Feasibility and Potential Impact of Brain Training Games on Cognitive and Emotional Functioning in Middle-Aged Adults. AB - OBJECTIVES: To investigate whether a commercially available brain training program is feasible to use with a middle-aged population and has a potential impact on cognition and emotional well-being (proof of concept). METHOD: Fourteen participants (ages 46-55) completed two 6-week training conditions using a crossover (counterbalanced) design: (1) experimental brain training condition and (2) active control "find answers to trivia questions online" condition. A comprehensive neurocognitive battery and a self-report measure of depression and anxiety were administered at baseline (first time point, before training) and after completing each training condition (second time point at 6 weeks, and third time point at 12 weeks). Cognitive composite scores were calculated for participants at each time point. RESULTS: Study completion and protocol adherence demonstrated good feasibility of this brain training protocol in healthy middle aged adults. Exploratory analyses suggested that brain training was associated with neurocognitive improvements related to executive attention, as well as improvements in mood. CONCLUSION: Overall, our findings suggest that brain training programs are feasible in middle-aged cohorts. We propose that brain training games may be linked to improvements in executive attention and affect by promoting cognitive self-efficacy in middle-aged adults. PMID- 29189047 TI - Combined serum free light chain levels are associated with carotid atherosclerosis in type 2 diabetes mellitus. AB - BACKGROUND: Patients with type 2 diabetes mellitus face an increased risk of cardiovascular events compared to non-diabetic counterparts. Chronic inflammation and activation of the immune system, including B-lymphocyte maturation is believed to play a role in atherosclerosis. Recent investigations suggest combined serum free light chains as a potential biomarker for cardiovascular events. The aim of this analysis was to investigate the association of combined serum free light chain with carotid atherosclerosis in subjects with type 2 diabetes mellitus. METHODS: We performed a cross-sectional analysis of data from a prospective single centre 2-year study of 97 patients with type 2 diabetes mellitus and insufficiently controlled cardiovascular risk factors. Complete data on combined serum free light chain, high-sensitivity C-reactive protein were available for 75 subjects. RESULTS: We analysed data of 26 female and 49 male subjects, aged 59 +/- 8 years. Their mean body mass index was 31.6 +/- 4.4 kg/m2, and the median B-score was 2 (interquartile range: 0-3). Significant positive correlations between combined serum free light chain and the B-score ( r = 0.38; p = 0.001) as well as combined serum free light chain and high-sensitivity C reactive protein ( r = 0.35; p = 0.002) were observed. The adjusted odds ratio for a half standard deviation increase in combined serum free light chain was 1.48 (95% confidence interval: 1.05-2.05) in an ordinal regression model for carotid B-score. CONCLUSION: In our study, combined serum free light chain was associated with carotid atherosclerosis in subjects with type 2 diabetes mellitus. PMID- 29189048 TI - Recall of structured radiology reports is significantly superior to that of unstructured reports. AB - OBJECTIVE: To measure recall of structured compared with unstructured radiology reports. METHODS: Institutional review board approval was obtained. Four hypothetical radiology reports, two structured and two unstructured reports, were created for the purposes of this study by an experienced consultant radiologist. The reports, each followed immediately by a multiple-choice questionnaire listing possible diagnoses from the report, were distributed to the members of two national physician associations using a web-based survey tool. Based on the number of correct responses, correct critical findings and incorrect responses, rates per number of potential diagnoses were calculated for each individual and averaged. The paired sign test compared results between structured and unstructured reports. RESULTS: 148 respondents completed the survey, 126 (85.1%) of whom were physicians. The mean percentage of incorrect diagnoses was 4.5% for structured reports compared with 16.7% for unstructured reports (p < 0.001). The average rate of critical diagnosis recall was 82.7% for structured reports and 65.1% for unstructured reports (p < 0.001). The average percentage of all diagnoses detected for structured compared with unstructured reports was 64.3 and 59.0%, respectively (p = 0.007). CONCLUSION: Recall of structured radiology reports is significantly superior to recall of unstructured reports immediately after reading the report. Advances in knowledge: A structured radiology report format can positively impact the referring clinician's ability to recall the critical findings with statistically significance.

PMID- 29189053 TI - Person-centred communication for emotional support in district nursing: SAGE and THYME model. AB - Patients on district nursing caseloads have multiple physical morbidities, and related emotional concerns. District nurses are ideally placed to assess and meet patients' emotional needs but in increasingly stretched workplaces, it is difficult to find time. There is also evidence that district nurses sometimes believe they lack skills to address patients' concerns. Traditional communication skills training is useful for encouraging patients to open up about their concerns, but less helpful at finding workable solutions. District nurses can be afraid to open a 'can of worms' of concerns that they are unable to deal with. SAGE and THYME is a person-centred, evidence-based communication skills model that addresses district nurses' concerns about time and skills. It provides a structure for conversations about concerns, and empowers patients to work with district nurses to find solutions. Research suggests that it is a promising model for district nursing practice. PMID- 29189054 TI - Sparing a thought for the homeless: Using a palliative care lens.

AB - There are over 400 000 cataract operations now being performed annually in the UK. With the majority of those patients being older people, comorbidities such as dementia or arthritis can prevent patients putting in their own post-operative eye drops. Where there is a lack of family or other support, district nursing services are often called upon to administer these eye drops, which are typically prescribed four times a day for 4 weeks, thus potentially totalling 112 visits for drop instillation per patient. To reduce the burden of these post-operative eye drops on district nursing services, administration of an intra-operative sub Tenon's depot steroid injection is possible for cataract patients who then do not require any post-operative drop instillation. As a trial of this practice, 16 such patients were injected in one year, thus providing a reduction of 1792 in the number of visits requested. Taking an estimated cost of each district nurse visit of L38, this shift in practice potentially saved more than L68 000; the additional cost of the injection over the cost of eye drops was just L8.80 for the year. This practice presents an opportunity to protect valuable community nursing resources, but advocacy for change in practice would be needed with secondary care, or via commissioners. PMID- 29189057 TI - Experience of emotion in frail older people towards the end of life: A secondary data analysis. AB - People are living longer, but with increased age comes greater frailty and multi morbidity. This secondary data analysis examines transcripts from interviews with 11 frail older people and 6 informal carers to explore emotion in relation to frailty and deteriorating health. Anger and frustration were frequently experienced with declining functional ability; sadness occurred with social isolation, loss of autonomy and independence; anxiety was evident when transition to a care home was discussed; and contentment was described when connecting with others. Reluctant acceptance emerged as a coping strategy. Insights gained from analysing emotion may inform communications training courses for community nurses, though further research is required.

AB - AIMS: The aim of this economic analysis was to estimate the economic impact of the On the Ground Education Programme (OGEP) within one local University Health Board (UHB) in Wales. BACKGROUND: The burden of managing chronic oedema can be considerable to the NHS. Developing innovative solutions to the care and management of patients with chronic oedema has the potential to deliver prudent, cost-effective and high quality care within NHS Wales. DESIGN: The study was a pilot Evaluation of the OGEP using retrospectively and prospectively collected patient recalled data. METHODS: A questionnaire collected health care service use data prior to receiving the OGEP (baseline) and at 3 months follow-up from 97 patients during the period June 2016 and January 2017. In addition, we analysed a patient reported health outcome using the EQ-5D 5L, which was completed by patients at the same two assessment points. RESULTS/FINDINGS: The total cost of managing chronic oedema in the 97 patients recruited was L563 729 (mean patient cost L5812 SD (L5870) at baseline and L445 098 (including the addition of intervention costs) (mean patient cost L4589 (SD L5465) at 3 months follow-up. Improvements in the EQ-5D 5L score increasing from 0.40 (SD 0.25) at baseline to 0.54 (SD 0.23) at 3 months follow-up. CONCLUSIONS: Our research show health care resource use and costs decreased, while health-related quality of life scores increased.

PMID- 29189062 TI - Factor V Inhibitors: A Diagnostic and Therapeutic Challenge. AB - Historically, inhibitors to coagulation factor V (FV) most often have developed in patients treated with bovine thrombin, a topical hemostatic agent used during surgical procedures. With the advent of newer hemostatic agents, and the concurrent diminished use of bovine thrombin, the incidence of FV inhibitors has fallen. Nevertheless, FV inhibitors are occasionally seen on an idiopathic basis as well as in association with medications, malignancies, autoimmune disorders, pregnancy, and infections. Factor V inhibitors may present with life-threatening bleeding or thrombosis, or they may be discovered incidentally as a coagulation screening test abnormality. Management of patients with FV inhibitors is challenging and consists of control of bleeding and eradication of the inhibitor. In this short overview we review the role of platelet and plasma FV in hemostasis and discuss the unique characteristics, clinical features, diagnosis, treatment, and prognosis associated with FV inhibitors. PMID- 29189063 TI - Classification, Morphology, Molecular Pathogenesis, and Outcome of Premalignant Lesions of the Pancreas. AB - CONTEXT: - Invasive pancreatic ductal adenocarcinoma has a greater than 90% mortality rate at 5 years. Understanding noninvasive, curable precursor lesions gives us the best hope for reducing mortality from pancreatic ductal adenocarcinoma. The 3 pancreatic precursor lesions that have been well studied include intraductal papillary mucinous neoplasm, mucinous cystic neoplasm, and pancreatic intraepithelial neoplasia. OBJECTIVE: - To give an update on the latest clinical, molecular, and pathologic advances in intraductal papillary mucinous neoplasm, mucinous cystic neoplasm, and pancreatic intraepithelial neoplasia for the general surgical pathologist. DATA SOURCES: - The current literature was analyzed and the authors' experiences with institutional and consult material were incorporated. CONCLUSIONS: - Our understanding of the molecular alterations that lead from pancreatic precursor lesion to invasive carcinoma continues to evolve. These advances aid clinicians in their treatment decisions and researchers in their search for actionable, druggable targets. PMID- 29189064 TI - The Updated World Health Organization Glioma Classification: Cellular and Molecular Origins of Adult Infiltrating Gliomas. AB - CONTEXT: - In the recently updated World Health Organization (WHO) classification of central nervous system tumors, our concept of infiltrating gliomas as a molecular dichotomy between oligodendroglial and astrocytic tumors has been codified. Advances in animal models of glioma and a wealth of sophisticated molecular analyses of human glioma tissue have led to a greater understanding of some of the biologic underpinnings of gliomagenesis. OBJECTIVE: - To review our understanding of gliomagenesis in the setting of the recently updated WHO classification of central nervous system tumors. Topics addressed include a summary of an updated diagnostic schema for infiltrating gliomas, the crucial importance of isocitrate dehydrogenase mutations, candidate cells of origin for gliomas, environmental and other posited contributing factors to gliomagenesis, and the possible role of chromatin topology in setting the stage for gliomagenesis. DATA SOURCES: - We conducted a primary literature search using PubMed. CONCLUSIONS: - With multidimensional molecular data sets spanning increasingly larger numbers of patients with infiltrating gliomas, our understanding of the disease at the point of surgical resection has improved dramatically and this understanding is reflected in the updated WHO classification. Animal models have demonstrated a diversity of candidates for glioma cells of origin, but crucial questions remain, including the role of neural stem cells, more differentiated progenitor cells, and glioma stem cells. At this stage the increase in data generated from human samples will hopefully inform the creation of newer animal models that will recapitulate more accurately the diversity of gliomas and provide novel insights into the biologic mechanisms underlying tumor initiation and progression.

AB - The purpose of this paper is to assess the value of accredited leg ulcer education in influencing changes in practice. This is a before and after educational evaluation that adopted a qualitative survey approach of 12 primary care nurses attending the Nurse-Led Assessment and Management of Leg Ulcers accredited CPD module at a London university. The findings revealed that 6 out of the 8 nurses who completed the final interviews were satisfied that all learning outcomes for the module had been met. All of the nurses commented they had changed at least one aspect of practice following the module with the majority stating a number of improvements had been made relating to improved knowledge, practical skills, treatment and patient concordance. The evaluation was limited to a small cohort of primary care nurses and further longitudinal research is required to investigate the effectiveness across multiple cohorts.

PMID- 29189069 TI - The impact of an educational intervention on home support workers' ability to detect early pressure ulcer damage. AB - OBJECTIVE: To investigate the impact of an educational intervention on home support workers' ability to detect early pressure ulcer damage. METHOD: A repeated measure design was employed to quantify the effectiveness of an educational intervention, consisting of one pre-test and two post-tests. RESULTS: Education was provided to home support workers and this was followed by an assessment of their ability to correctly classify 20 photographs detailing varying stages of skin damage severity. At the baseline (pre-education), 58% of the photographs were classified correctly. At post-test 1, 55% of the photographs were classified correctly. In post-test 2 this increased to 58%, achieving the original baseline scores. There was a moderate negative relationship between pre training and post-test 2 scores (r=-0.44; n=27; p=0.02). CONCLUSIONS: The educational intervention has been shown not to have a statistically significantly positive effect on home support workers' ability to detect early pressure ulcer damage. The moderate negative relationship between pre-training and post-test 2 scores concur with the aforementioned qualitative findings, and similarly indicate behaviour associated with individuals experiencing difficulty comprehending new health terms.

Current management of wound infection is largely subjective and relies on the knowledge of the health care professional to identify and initiate treatment. In response, we have developed an infection prediction and assessment tool. The Wound Infection Risk-Assessment and Evaluation tool (WIRE) and its management strategy is a tool with the aim to bring objectivity to infection prediction, assessment and management. A local audit carried out indicated a high infection prediction rate. More work is being done to improve its effectiveness. PMID- 29189076 TI - Extremit-Ease compression garment: A review and cases. AB - The rates of chronic oedema in the US continue to grow from multiple causative factors. One such factor is the skyrocketing rates of morbid obesity. There are about 40 million obese people in the US today. Among those people, the prevalence rate of lymphoedema is 74% ( Fife and Carter, 2008 ). Treatment usually involves some type of compression for life, but that is easier said than done. Many patients with chronic oedema have dexterity issues or have limited abilities to put on tight compression options. This article explores a product that has just been recently launched on the market: the Extremit-Ease(r) compression garment. This article also looks at five case studies involving the product to evaluate its effectiveness in the treatment of this growing condition. We explore the increasing problem of chronic oedema, specifically oedema caused by lymphoedema and venous stasis, and how Extremit-Ease compression garments could assist patient compliance with the gold standard treatment.

PMID- 29189078 TI - Use of metal/metal oxide spherical cluster and hydroxyl metal coordination complex for descriptor calculation in development of nanoparticle cytotoxicity classification model. AB - Computational approaches have been suggested as an informative tool for risk assessment of nanomaterials. Nano (quantitative) structure-activity relationship, nano-(Q)SAR, models have been developed to predict toxicity of metal oxide (MOx) nanoparticles (NPs); however, the packing structure and cluster of nanoparticle have been included for the descriptor calculation in only two studies. This study proposed spherical cluster and hydroxyl metal coordination complex to calculate descriptors for development of nanoparticle cytotoxicity classification model. The model cluster was generated from metal (M) or MOx crystal structure to calculate physicochemical properties of M/MOx NPs and the hydroxyl metal coordination complex was used to calculate the properties of the metal cation in an aqueous environment. Data were collected for 2 M and 19 MOx NPs in human bronchial epithelial cell lines and murine myeloid cell lines at 100 MUg/ml after 24 hours exposure. The model was developed with scaled HOMO energy of the model cluster and polarizability of the hydroxyl metal coordination complex, as reactivity of the particles and the cations explained cause of cytotoxic action by M/MOx NPs. As the developed model achieved 90.31% accuracy, the classification model in this work can be used for virtual screening of toxic action of M/MOx NPs. PMID- 29189079 TI - Triterpenoid saponins from the buds of Lonicera similis. AB - Four new lupane triterpenoid saponins, along with one known lupane and eight hederagenin saponins, were isolated from the EtOH extract of the buds of Lonicera similis Hemsl. The structures of the new compounds were established as 3-O-beta-D glucopyranosyl-(1->2)-beta-D-glucopyranosyl 23-hydroxybetulinic acid 28-O-beta-D glucopyranosyl ester (lonisimilioside A, 1), 3-O-beta-D-glucopyranosyl-(1->2) beta-D-glucopyranosyl 23-hydroxybetulinic acid 28-O-beta-D-glucopyranosyl-(1->6) beta-D-glucopyranosyl ester (lonisimilioside B, 2), 3-O-beta-D-glucopyranosyl-(1 >2)-beta-D-glucopyranosyl betulinic acid 28-O-beta-D-glucopyranosyl-(1->6)-beta-D glucopyranosyl ester (lonisimilioside C, 3) and 3-O-beta-D-glucopyranosyl-(1->2) beta-D-glucopyranosyl-(1->6)-beta-D-glucopyranosyl betulinic acid 28-O-beta-D glucopyranosyl ester (lonisimilioside D, 4), respectively. The cytotoxic activities of the isolates against human cancer cell lines HepG2, MCF-7 and A-549 were evaluated. Only the monodesmosidic saponin with a free carboxyl group at C 28 (12) exhibited significant cytotoxicities against HepG2, MCF-7 and A-549 cell lines with the IC50 values of 8.98 +/- 0.19, 12.48 +/- 0.45 and 11.62 +/- 0.54 MUM, respectively. Furthermore, Hoechst fluorescence 33342 staining was used to demonstrate that 12 could induce HepG2 and A-549 cells apoptosis significantly.

PMID- 29189083 TI - Effectiveness of physiotherapy in elderly patients with dementia: a prospective, comparative analysis. AB - BACKGROUND: The aim of this study was to assess the efficacy of physiotherapy in nursing home patients with comorbid dementia. MATERIALS AND METHODS: The study group consisted of 88 patients, including 48 people with dementia and 40 people without dementia. Before and after physiotherapy, the Mini Mental State Examination and Barthel Index were used. RESULTS: Elderly patients without dementia achieved a greater improvement in functional status. The level of cognitive functioning at the time of admission to a nursing home, but not the patient's functional status, had a significant impact on physiotherapy efficacy. CONCLUSION: Understanding the role of dementia in the rehabilitation process is important for care planning. More research is required to ascertain the efficacy of physiotherapy in people with moderate to severe dementia, including the best strategies to improve their functional status. Implications for Rehabilitation The level of cognitive function is important in the rehabilitation process, and it influences effectiveness of physiotherapy. Physiotherapy efficacy in the group of patients with coexisting dementia is lower than that in patients without dementia. Regular physiotherapy can also improve functional status in patients with coexisting dementia. The results of the study may have utilitarian implications, leading to a change in therapy regimens at physiotherapy centres treating disabled chronically ill people with coexisting dementia. PMID- 29189084 TI - Depressive symptoms and their risk factors in midlife women in the Middle East: a systematic review. AB - INTRODUCTION: Women may experience different menopausal symptoms across different cultures around the world. The purpose of this study was to determine the prevalence and contributing factors of depression in midlife women in the Middle East. METHODS: Electronic databases including PubMed, Medline, PsycINFO, CINAHL, Web of Science, SCOPUS, and Google scholar were searched. The quality of articles was assessed by using the risk of bias tool. RESULTS: Sixteen articles were used for this review. The prevalence for depressive symptoms in perimenopausal women is higher than in premenopausal women. The overall data also suggest that depressive symptoms may be more prevalent in postmenopausal women than in premenopausal women. Studies reported sociodemographic, physical, psychological, cultural and sexual risk factors for depressive symptoms in middle-aged women. Risk of bias for a majority of the studies conducted in the Middle Eastern region on depression in midlife was moderate. CONCLUSION: Consistent with other areas in the world, midlife women in the Middle East region are at higher risk for depression due to the presence of different factors. High-quality longitudinal studies of representative samples, using validated questionnaires, are needed to provide more accurate prevalence data and the association between menopause and menopausal symptoms in women in the Middle East. PMID- 29189085 TI - Sharing End-of-Life Care Preferences with Family Members: Who Has the Discussion and Who Does Not. AB - BACKGROUND: Research suggests that greater engagement in family discussions concerning end-of-life (EOL) care preferences could improve advance care planning and EOL outcomes. However, a substantial number of people have not had such discussions. OBJECTIVE: The study's objective was to understand attitudes and experiences influencing engagement in discussions of EOL care preferences with family members, including the role of healthcare providers in such discussions. METHODS: We conducted focus group interviews with 36 non-Hispanic White, African American, and Hispanic community-dwelling participants. Participants were divided among groups to explore differences between those who had or had not engaged in EOL care discussions. Atlas.ti version 7 was used to analyze data employing an open-coding method. RESULTS: Participants' mean age was 70 (range: 58-87); three fourths were female (n = 27). Twenty were white, non-Hispanic; 10 were African American; and 6 were Hispanic. Four themes emerged from the data, (1) being proactive or passive/reactive; (2) perceiving discussion of death as normal or abnormal; (3) response to family resistance/disconnection; and (4) knowledge acquired. A fifth theme, the role of healthcare providers in family EOL care discussions, resulted from facilitators' questions. Theme examination led to identification of a central category, decision-making. CONCLUSIONS: It is important to understand the differing experiences and attitudes of those who do or do not engage in EOL discussions. Research is needed on healthcare practitioners' use of decision-making tools to help patients discuss their EOL care preferences with family and others, the goal of which is to provide care consistent with patients' goals. PMID- 29189086 TI - Case series of diagnostic shift from bipolar disorder to schizoaffective disorder. AB - OBJECTIVE: To describe three cases of diagnostic shift from bipolar I disorder (BD) to schizoaffective disorder (SAD). METHODS: BD patients were clinically assessed and followed up in a mood disorder program. A questionnaire was applied to assess clinical and socio-demographic characteristics, and a Structured Clinical Interview (SCID-I) was conducted. RESULTS: We identified three patients with diagnosis conversion to SAD from 2005 to 2016. The mean time between BD diagnosis and the diagnostic shift to SAD was 9 years. CONCLUSIONS: Psychotic symptoms may become persistent, chronic and unrelated to the presence of mood episodes many years after the beginning of BD. Psychiatrists should be aware of this and reassess the diagnosis during the longitudinal course of BD, especially in those patients who present psychotic symptoms. PMID- 29189087 TI - Diagnostic usefulness of the QuantiFERON-TB gold in-tube test (QFT-GIT) for tuberculous vertebral osteomyelitis. AB - BACKGROUND: Interferon (IFN)-gamma-releasing assay for diagnosing tuberculosis (TB) has shown promise; however, there are only a few reports on usefulness of the QuantiFERON-TB Gold In-Tube test (QFT-GIT) for diagnosing TB vertebral osteomyelitis. METHODS: All patients presenting at a tertiary hospital between January 2010 and July 2016 with suspected TB vertebral osteomyelitis were retrospectively enrolled to evaluate the diagnostic performance of QFT-GIT. We used QFT-GIT to measure the IFN-gamma response to ESAT-6, CFP-10 and TB7.7. RESULTS: A total of 141 patients were enrolled; 32 (23%) were categorized as having confirmed TB, (1%) as probable TB, 14 (10%) as possible TB and 93 (66%) as not TB. Of these, 16 patients with probable and possible TB were excluded from the final analysis. Chronic granulomas with/without necrosis, acid-fast bacilli stain, M. tuberculosis polymerase chain reaction and cultures for M. tuberculosis were positive in 14 (44%), 12 (38%), 22 (69%) and 28 (88%) patients, respectively, among the 32 patients with confirmed TB. The overall sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio for a positive result, and likelihood ratio for a negative result of the QFT-GIT for TB vertebral osteomyelitis were 91% (95% confidence interval [CI], 75 98%), 65% (95% CI, 54-75%), 50% (95% CI, 42-58%), 95% (95% CI, 86-98%), 2.59 (95% CI, 1.89-3.55) and 0.14 (95% CI, 0.05-0.43), respectively. CONCLUSION: The QFT GIT appears to be a useful adjunct test for diagnosing TB vertebral osteomyelitis because the negative test results may be useful for excluding a diagnosis of active TB vertebral osteomyelitis.

METHODS: A total of 183 adults with sensory loss and 133 spouses participated in an online survey and were followed up six months later. Coping and well-being were measured using the Brief Coping Orientation to Problems Experienced Scale (Brief COPE) and the five-item World Health Organization Well Being Index (WHO-5), respectively. Cross-sectional and longitudinal intra- and interpersonal effects of coping on psychological well-being were analyzed using a structural equation modeling approach. RESULTS: Results showed that a significant portion of adults with sensory loss (32.4%) and spouses (23.8%) had poor well being, and this remained stable over the six-month period. Coping styles associated with the well-being of adults with sensory loss included active coping, avoidance, distraction, venting and spouse support seeking. Coping styles associated with the well-being of spouses included support seeking, distraction, venting, avoidance (by partner) and humor (by partner). CONCLUSION: The results highlight the need to support the well-being of adults with sensory loss and their spouses in rehabilitation, and the importance of both intra- and interpersonal coping in the adjustment process. Implications for rehabilitation Rehabilitation specialists and social workers working with adults with sensory loss should, where possible, incorporate family members into support plans. Rehabilitation specialists and social workers working in sensory rehabilitation should be mindful of how the coping styles of one partner can impact the well being of their significant other. In addition to promoting positive coping behaviors, such as planning and support seeking, rehabilitation specialists and social workers should also take care to identify and reduce maladaptive coping behaviors such as avoidance and distraction. Online and print information for spouses on how to cope with a partner's sensory loss should be available and accessible for couples attending sensory rehabilitation clinics.

AB - Whooper swan Cygnus cygnus interferon alpha (CyIFN-alpha) gene was amplified from genomic DNA in the liver of whooper swan, which encodes a 192-amino acid protein containing a 29-amino acid signal peptide. Bioinformatics analysis showed it containes 7 cysteine residues and 5 alpha helices. After expression in prokaryote, purification and renaturation, CyIFN-alpha was analyzed on its physicochemical property and antiviral activity. In chicken embryo fibroblasts, CyIFN-alpha exerted more superior anti-vesicular stomatitis virus (VSV), avian influenza virus (AIV), and Newcastle disease virus (NDV) activity than chicken IFN-alpha, an effective therapeutic agent used for viral infections clinically. Contrarily, these antiviral activities were abrogated by rabbit anti-CyIFN-alpha in vitro. Moreover, CyIFN-alpha was shown to be highly sensitive to trypsin, however, it remained stable despite changes in pH and temperature. In addition, CyIFN-alpha induced the transcription of Mx1, ISG12, and IFIT5 (ISG58) genes, as well as the expression of Mx1 protein, in a time-dependent manner. In conclusion, we first cloned and expressed CyIFN-alpha and tested its biological activity in vitro. Our findings facilitate further research on the role of type I IFN in antiviral defense responses in whooper swan and other Natatores. PMID- 29189089 TI - Interferon-inducible Mx1 protein is highly expressed in renal tissues from treatment-naive lupus nephritis, but not in those under immunosuppressive treatment. AB - OBJECTIVES: The aim of this study was to clarify the consequences of Mx1, one of the IFN-inducible proteins, in the peripheral blood as well as in renal tissues in patients with systemic lupus erythematosus (SLE). PATIENTS AND METHODS: Mx1 protein concentrations in (PBMCs) from 18 SLE patients mostly in their stable disease status, 11 IgA nephropathy (IgAN) patients, 5 ANCA-associated vasculitis (AAV) patients and 16 healthy controls were measured using enzyme-linked immunosorbent assay (ELISA). Mx1 expression in renal specimens from 18 patients with lupus nephritis (LN), 18 with IgAN and 10 with AAV were evaluated using immunohistochemistry. RESULTS: Mx1 protein concentrations in lysates of PBMCs were significantly higher in SLE patients compared with those in other three groups. Mx1-positive area in renal tissues was significantly dominant in both glomeruli and renal tubules of LN compared with other renal diseases. Renal Mx1 protein levels were lower in LN after immunosuppressive treatment, compared with those from immunosuppressant-naive patients. CONCLUSION: Mx1 levels were upregulated in lupus peripheral blood even when their disease activities were stable. On the other hand, Mx1 was highly expressed in kidneys from patients with LN before treatment, which was decreased after immunosuppressive treatment. These results suggest that Mx1 is a potential marker for the diagnosis of SLE in the peripheral blood and also for the activity of lupus nephritis in the kidney.

AB - Allowing physicians to write a do not resuscitate (DNR) or do not administer cardiopulmonary resuscitation order after properly informing patients and their families that death would be irreversible offers a more rational and compassionate approach than traditional shared decision making in establishing a DNR status for some hospitalized patients. PMID- 29189092 TI - Serial semi-quantitative measurement of fecal calprotectin in patients with ulcerative colitis in remission. AB - BACKGROUND: Fecal calprotectin (FC) correlates with clinical and endoscopic activity in ulcerative colitis (UC), and it is a good predictor of relapse. However, its use in clinical practice is constrained by the need for the patient to deliver stool samples, and for their handling and processing in the laboratory. The availability of hand held devices might spread the use of FC in clinical practice. OBJECTIVES: To evaluate the usefulness of a rapid semi quantitative test of FC in predicting relapse in patients with UC in remission. MATERIALS AND METHODS: Prospective, multicenter study that included UC patients in clinical remission for >=6 months on maintenance treatment with mesalamine. Patients were evaluated clinically and semi-quantitative FC was measured using a monoclonal immunochromatography rapid test at baseline and every three months until relapse or 12 months of follow-up. RESULTS: One hundred and ninety-one patients had at least one determination of FC. At the end of follow-up, 33 patients (17%) experienced clinical relapse. Endoscopic activity at baseline (p = .043) and having had at least one FC > 60 MUg/g during the study period (p = .03) were associated with a higher risk of relapse during follow-up. We obtained a total of 636 semi-quantitative FC determinations matched with a three-month follow-up clinical assessment. Having undetectable FC was inversely associated with early relapse (within three months), with a negative predictive value of 98.6% and a sensitivity of 93.9%. CONCLUSIONS: Serial, rapid semi-quantitative measurement of FC may be a useful, easy and cheap monitoring tool for patients with UC in remission. PMID- 29189093 TI - A Palliative Radiation Oncology Consult Service's Impact on Care of Advanced Cancer Patients. AB - INTRODUCTION: Palliative radiation therapy (PRT) is a commonly utilized intervention for symptom palliation among patients with metastatic cancer, yet it is under-recognized as a distinct area of subspecialty within radiation oncology. OBJECTIVE: We developed a multidisciplinary service model within radiation oncology called the Palliative Radiation Oncology Consult (PROC) service to improve the quality of cancer care for advanced cancer patients. We assessed the service's impact on patient-related and healthcare utilization outcomes. DESIGN: Patients were included in this observational cohort study if they received PRT at a single tertiary care hospital between 2009 and 2017. We compared outcomes of patients treated after (post-intervention group) to those treated before (control group) PROC's establishment using unadjusted and propensity score adjusted analyses. RESULTS: Of the 450 patients in the cohort, 154 receive PRT pre- and 296 after PROC's establishment. In comparison to patients treated pre-PROC, post PROC patients were more likely to undergo single-fraction radiation (RR: 7.74, 95% CI: 3.84-15.57) and hypofraction (2-5 fraction) radiation (RR: 10.74, 95% CI: 5.82-19.83), require shorter hospital stays (21 vs. 26.5 median days, p = 0.01), and receive more timely specialty-level palliative care (OR: 2.65, 95% CI: 1.56 4.49). Despite shortened treatments, symptom relief was similar (OR: 1.35, 95% CI: 0.80-2.28). CONCLUSION: The PROC service was associated with more efficient radiation courses, substantially reduced hospital length of stays, and more timely palliative care consultation, without compromising symptom improvements. These results suggest that a multidisciplinary care delivery model can lead to enhanced quality of care for advanced cancer patients. PMID- 29189094 TI - FijiWingsPolarity: An open source toolkit for semi-automated detection of cell polarity. AB - Epithelial cells are defined by apical-basal and planar cell polarity (PCP) signaling, the latter of which establishes an orthogonal plane of polarity in the epithelial sheet. PCP signaling is required for normal cell migration, differentiation, stem cell generation and tissue repair, and defects in PCP have been associated with developmental abnormalities, neuropathologies and cancers. While the molecular mechanism of PCP is incompletely understood, the deepest insights have come from Drosophila, where PCP is manifest in hairs and bristles across the adult cuticle and organization of the ommatidia in the eye. Fly wing cells are marked by actin-rich trichome structures produced at the distal edge of each cell in the developing wing epithelium and in a mature wing the trichomes orient collectively in the distal direction. Genetic screens have identified key PCP signaling pathway components that disrupt trichome orientation, which has been measured manually in a tedious and error prone process. Here we describe a set of image processing and pattern-recognition macros that can quantify trichome arrangements in micrographs and mark these directly by color, arrow or colored arrow to indicate trichome location, length and orientation. Nearest neighbor calculations are made to exploit local differences in orientation to better and more reliably detect and highlight local defects in trichome polarity. We demonstrate the use of these tools on trichomes in adult wing preps and on actin rich developing trichomes in pupal wing epithelia stained with phalloidin. FijiWingsPolarity is freely available and will be of interest to a broad community of fly geneticists studying the effect of gene function on PCP. PMID- 29189096 TI - Regulation and functions of RhoU and RhoV. AB - Rho GTPases play central roles in a wide variety of cellular processes, including cytoskeletal dynamics, cell adhesion and cell polarity. RhoU and RhoV are Rho GTPases that have some atypical properties compared with classical Rho family members, such as the presence of N- and C-terminal extension regions, unusual GDP/GTP cycling and post-translational modification by palmitoylation but not prenylation. Their activity and localization is regulated by the N-terminal and C terminal regions, and so far no GEFs or GAPs have been identified for them. Similar to Rac and Cdc42, they interact with PAK serine/threonine kinases, and in the case of PAK4, this interaction leads to RhoU protein stabilization. In cells, RhoU and RhoV alter cell shape and cell adhesion, which probably underlies some of the phenotypes reported for these proteins in vivo, for example in heart development and epithelial morphogenesis. However, the molecular basis for these functions of RhoU and RhoV remains to be characterized. PMID- 29189095 TI - Pregnancy history, coronary artery calcification and bone mineral density in menopausal women. AB - OBJECTIVE: This study examined relationships, by pregnancy histories, between bone mineral density (BMD) and coronary artery calcification (CAC) in postmenopausal women. METHODS: Forty women identified from their medical record as having pre-eclampsia (PE) were age/parity-matched with 40 women having a normotensive pregnancy (NP). Vertebral (T4-9) BMD and CAC were assessed by quantitative computed tomography in 73 (37 with PE and 36 with NP) of the 80 women. Analyses included linear regression using generalized estimating equations. RESULTS: Women averaged 59 years of age and 35 years from the index pregnancy. There were no significant differences in cortical, trabecular or central BMD between groups. CAC was significantly greater in the PE group (p = 0.026). In multivariable analysis, CAC was positively associated with cortical BMD (p = 0.001) and negatively associated with central BMD (p = 0.036). There was a borderline difference in the association between CAC and central BMD by pregnancy history (interaction, p = 0.057). CONCLUSIONS: Although CAC was greater in women with a history of PE, vertebral BMD did not differ between groups. However, both cortical and central BMD were associated with CAC. The central BMD association was marginally different by pregnancy history, suggesting perhaps differences in underlying mechanisms of soft tissue calcification. PMID- 29189097 TI - A Fungus-Inducible Pepper Carboxylesterase Exhibits Antifungal Activity by Decomposing the Outer Layer of Fungal Cell Walls. AB - Colletotrichum species are major fungal pathogens that cause devastating anthracnose diseases in many economically important crops. In this study, we observed the hydrolyzing activity of a fungus-inducible pepper carboxylesterase (PepEST) on cell walls of C. gloeosporioides, causing growth retardation of the fungus by blocking appressorium formation. To determine the cellular basis for the growth inhibition, we observed the localization of PepEST on the fungus and found the attachment of the protein on surfaces of conidia and germination tubes. Moreover, we examined the decomposition of cell-wall materials from the fungal surface after reaction with PepEST, which led to the identification of 1,2 dithiane-4,5-diol (DTD) by gas chromatography mass spectrometry analysis. Exogenous DTD treatment did not elicit expression of defense-related genes in the host plant but did trigger the necrosis of C. gloeosporioides. Furthermore, the DTD compound displayed protective effects on pepper fruits and plants against C. gloeosporioides and C. coccodes, respectively. In addition, DTD was also effective in preventing other diseases, such as rice blast, tomato late blight, and wheat leaf rust. Therefore, our results provide evidence that PepEST is involved in hydrolysis of the outmost layer of the fungal cell walls and that DTD has antifungal activity, suggesting an alternative strategy to control agronomically important phytopathogens. PMID- 29189098 TI - The effects of ovarian hormones on stressor-induced hormonal responses, glucocorticoid receptor expression and translocation, and genes related to receptor signaling in adult female rats. AB - Estradiol potentiates hypothalamic-pituitary-adrenal activity and delays the return of glucocorticoid secretion to baseline after a stressor exposure in female rats; we investigated whether estradiol effects involve actions on glucocorticoid receptor (GR) translocation and expression of receptor co chaperones. In Experiment 1 intact females and ovariectomized (OVX) females were treated for four days with vehicle (VEH), 17beta-estradiol benzoate (EB), or EB and progesterone (EB + P). Samples were taken from rats in the home cage (baseline) or after 30 min of restraint stress in a plastic restrainer (post restraint) (n = 10/group). OVX-VEH treatment reduced baseline and post-restraint plasma concentrations of corticosterone versus all other treatments. Western blots indicated that OVX-VEH treated rats had greater hippocampal cytosolic GR expression than other treatments. Stress increased hippocampal nuclear GR expression, but without treatment differences. In Experiment 2 OVX rats were treated daily with VEH, EB, or EB + P (n = 8/group). OVX-VEH rats showed a lower stimulation of corticosterone secretion by restraint stress than other treatments and OVX-EB + P treated rats had lower concentrations than the OVX-EB group, suggesting progesterone mitigated estradiol effects. Quantitative polymerase chain reaction experiments indicated that stress increased Fkbp5 mRNA in the ventral hippocampus, with no effect of stress or treatment on Nr3c1 (GR), Nr3c2 (MR), Fkbp4, Bag1, or Ncoa1 (SRC-1) expression. Thus, the hypothesis is that estradiol effects on negative feedback are mediated by altered expression of receptor co-chaperones or co-modulators in the hippocampus was not supported. Estradiol may blunt feedback by limiting the availability of cytosolic GR protein. PMID- 29189099 TI - Creative prosthetic foot selection enables successful ambulation in stiletto high heels. AB - BACKGROUND: Walking in high heels presents biomechanical challenges, yet they remain part of many women's attire. However, women with a lower limb amputation are limited in available footwear options. Case description and methods: This case study is in response to one patient's assertion that she walked better and more symmetrically in heels than flat shoes with her below-knee prosthesis. She underwent gait analysis in athletic shoes and 10-cm stiletto high heels worn with a pediatric running foot to determine if these claims could be substantiated through biomechanical measures. Global gait asymmetry indices were calculated. Findings and outcomes: Asymmetry indices were nearly identical between athletic shoes and heels but joint-level findings differed substantially. Ankle mechanics were more symmetrical in heels but hip mechanics were less. CONCLUSION: The maintenance of symmetry in stiletto high heels does not imply maintenance of gait quality, as high heels are known to adversely affect some components walking mechanics. Clinical relevance Returning to high-heel wear is achievable for prosthesis users. Accommodations can be made using creativity in prosthetic foot selection to enable successful ambulation; however, attention to gait mechanics may be important for patient safety. PMID- 29189100 TI - A Soft Tube-Climbing Robot. AB - This article demonstrates a pneumatically actuated soft robot capable of navigating the inside of a tube. This robot was built using buckling pneumatic actuators (vacuum-actuated muscle-inspired pneumatic structures, or VAMPs). The tube climber can navigate through a tube with turns, inclines, and varying diameters. The robot is also able to remove obstacles (of more than 10 times its own weight) from tubes to perform a clearing function. It maintains climbing and clearing performance in wet conditions and under water. The tube climber is lightweight and completely soft and thus has the potential to be collaborative (i.e., work with humans) and also to interact safely with delicate environments. PMID- 29189101 TI - Pharmacokinetics and pharmacodynamics of the nucleoside sparing dual regimen containing rilpivirine plus darunavir/ritonavir in treatment-naive HIV-1-infected individuals. AB - BACKGROUND: We aimed at investigating the antiviral activity and the pharmacokinetics of the dual antiretroviral (ARV) combination of rilpivirine plus darunavir/ritonavir 25/800/100 mg once-daily in naive HIV-1-infected individuals (NHII) with different baseline viral loads. SETTINGS: Pharmacokinetic/pharmacodynamics study in ARV-naive HIV-infected individuals. METHODS: The primary endpoint was the number of NHII with HIV-RNA < 40 copies/mL at week 48. Secondary endpoints included rilpivirine/darunavir/ritonavir pharmacokinetics, HIV-RNA decay, and changes in ECG QT interval. RESULTS: Thirty six individuals were enrolled, 18 with a baseline viral load < 100,000 copies/mL (group A) and 18 with a baseline viral load > 100,000 copies/mL (group B). All but 1 (HIV-RNA = 63 copies/mL) subjects achieved viral load < 50 copies/mL by week 36, and all at week 48. Median (range) HIV-RNA reduction (Log10 copies/mL) was 1.3 (0.6-1.9) over the first week, with no differences between groups A and B. Geometric mean and 95%CI rilpivirine Cmax, Ctrough, AUC were 183 (165-239), 114 (104-109) ng/mL, 2966 (2704-3820) ng h/mL. No QTcF interval changes were recorded. CONCLUSIONS: rilpivirine/darunavir/ritonavir could be efficacious, with limited short-term toxicity in ARV-naive patients. Although rilpivirine was co administered with ritonavir, its exposure was within ranges measured during phase III trials. PMID- 29189103 TI - Protein-protein interaction networks and different clustering analysis in Burkitt's lymphoma. AB - OBJECTIVE: Burkitt's lymphoma (BL) is a highly aggressive malignant lymphoma, its molecular biological mechanism has not been fully investigated. The construction of protein-protein interaction (PPI) networks and the identification of complexes through a cluster analysis are important research directions in the post-genome era. However, different cluster analysis algorithms have their own characteristics, and a single analysis has some limitations. In this study, we obtained the target and pathway information of BL using different clustering analyses. MATERIAL AND METHODS: First, we obtained 50 BL genes by screening the Online Mendelian Inheritance in Man (OMIM) database; their related genes were further extracted from the literature. The PPI network was constructed with the Search Tool for Retrieval of Interacting Genes/Proteins (STRING). Afterward, the interaction data were input in Cytoscape3.4.0 software and related plug-ins were used to implement topology analysis and clustering analysis. Functional analysis based on the Kyoto Encyclopedia of Genes and Genomes (KEGG) database were used to characterize the biological importance of the clusters. RESULTS: We constructed a PPI network consisting of 459 nodes (proteins) and 1399 sides (interactions), 12 genes and 8 signaling pathways were found to be closely related to BL. CONCLUSION: In this study, the use of combined algorithms to analyse gene interactions provides a new perspective for network-based analysis. The results of this study reveal new insights into the molecular mechanisms underlying BL, which may be novel therapeutic targets for disease management and may provide a bioinformatic basis for the further understanding of BL. PMID- 29189102 TI - Changes in Signal Intensity of the Dentate Nucleus and Globus Pallidus in Pediatric Patients: Impact of Brain Irradiation and Presence of Primary Brain Tumors Independent of Linear Gadolinium-based Contrast Agent Administration. AB - Purpose To determine whether whole-brain irradiation, chemotherapy, and primary brain pathologic conditions affect magnetic resonance (MR) imaging signal changes in pediatric patients independent of the administration of gadolinium-based contrast agents (GBCAs). Materials and Methods This institutional review board approved, HIPAA-compliant study included 144 pediatric patients who underwent intravenous GBCA-enhanced MR imaging examinations (55 patients with primary brain tumors and whole-brain irradiation, 19 with primary brain tumors and chemotherapy only, 52 with primary brain tumors without any treatment, and 18 with neuroblastoma without brain metastatic disease). The signal intensities (SIs) in the globus pallidus (GP), thalamus (T), dentate nucleus (DN), and pons (P) were measured on unenhanced T1-weighted images. GP:T and DN:P SI ratios were compared between groups by using the analysis of variance and were analyzed relative to group, total cumulative number of doses of GBCA, age, and sex by using multivariable linear models. Results DN:P ratio for the radiation therapy group was greater than that for the other groups except for the group of brain tumors treated with chemotherapy (P < .05). The number of GBCA doses was correlated with the DN:P ratio for the nontreated brain tumor group (P < .0001). The radiation therapy-treated brain tumor group demonstrated higher DN:P ratios than the nontreated brain tumor group for number of doses less than or equal to 10 (P < .0001), whereas ratios in the nontreated brain tumor group were higher than those in the radiation therapy-treated brain tumor group for doses greater than 20 (P = .05). The GP:T ratios for the brain tumor groups were greater than that for the neuroblastoma group (P = .01). Conclusion Changes in SI of the DN and GP that are independent of the administration of GBCA occur in patients with brain tumors undergoing brain irradiation, as well as in patients with untreated primary brain tumors.

AB - Previous immunological studies in atomic bomb survivors have suggested that radiation exposure leads to long-lasting changes, similar to immunological aging observed in T-cell-adaptive immunity. However, to our knowledge, late effects of radiation on dendritic cells (DCs), the key coordinators for activation and differentiation of T cells, have not yet been investigated in humans. In the current study, we hypothesized that numerical and functional decreases would be observed in relationship to radiation dose in circulating conventional DCs (cDCs) and plasmacytoid DCs (pDCs) among 229 Japanese A-bomb survivors. Overall, the evidence did not support this hypothesis, with no overall changes in DCs or functional changes observed with radiation dose. Multivariable regression analysis for radiation dose, age and gender effects revealed that total DC counts as well as subpopulation counts decreased in relationship to increasing age. Further analyses revealed that in women, absolute numbers of pDCs showed significant decreases with radiation dose. A hierarchical clustering analysis of gene expression profiles in DCs after Toll-like receptor stimulation in vitro identified two clusters of participants that differed in age-associated expression levels of genes involved in antigen presentation and cytokine/chemokine production in cDCs. These results suggest that DC counts decrease and expression levels of gene clusters change with age. More than 60 years after radiation exposure, we also observed changes in pDC counts associated with radiation, but only among women. PMID- 29189105 TI - Characterization of Diffuse Intrinsic Pontine Glioma Radiosensitivity using Synchrotron Microbeam Radiotherapy and Conventional Radiation Therapy In Vitro. AB - Synchrotron microbeam radiation therapy is a promising preclinical radiotherapy modality that has been proposed as an alternative to conventional radiation therapy for diseases such as diffuse intrinsic pontine glioma (DIPG), a devastating pediatric tumor of the brainstem. The primary goal of this study was to characterize and compare the radiosensitivity of two DIPG cell lines (SF7761 and JHH-DIPG-1) to microbeam and conventional radiation. We hypothesized that these DIPG cell lines would exhibit differential responses to each radiation modality. Single cell suspensions were exposed to microbeam (112, 250, 560, 1,180 Gy peak dose) or conventional (2, 4, 6 and 8 Gy) radiation to produce clonogenic cell-survival curves. Apoptosis induction and the cell cycle were also analyzed five days postirradiation using flow cytometry. JHH-DIPG-1 cells displayed greater radioresistance than SF7761 to both microbeam and conventional radiation, with higher colony formation and increased accumulation of G2/M-phase cells. Apoptosis was significantly increased in SF7761 cells compared to JHH-DIPG-1 after microbeam irradiation, demonstrating cell-line specific differential radiosensitivity to microbeam radiation. Additionally, biologically equivalent doses to microbeam and conventional radiation were calculated based on clonogenic survival, furthering our understanding of the response of cancer cells to these two radiotherapy modalities. PMID- 29189106 TI - Nonlinear Tracking Control of a Conductive Supercoiled Polymer Actuator. AB - Artificial muscle actuators made from commercial nylon fishing lines have been recently introduced and shown as a new type of actuator with high performance. However, the actuators also exhibit significant nonlinearities, which make them difficult to control, especially in precise trajectory-tracking applications. In this article, we present a nonlinear mathematical model of a conductive supercoiled polymer (SCP) actuator driven by Joule heating for model-based feedback controls. Our efforts include modeling of the hysteresis behavior of the actuator. Based on nonlinear modeling, we design a sliding mode controller for SCP actuator-driven manipulators. The system with proposed control law is proven to be asymptotically stable using the Lyapunov theory. The control performance of the proposed method is evaluated experimentally and compared with that of a proportional-integral-derivative (PID) controller through one-degree-of-freedom SCP actuator-driven manipulators. Experimental results show that the proposed controller's performance is superior to that of a PID controller, such as the tracking errors are nearly 10 times smaller compared with those of a PID controller, and it is more robust to external disturbances such as sensor noise and actuator modeling error.

AB - Background The incidence of stroke in young adults is increasing. While many young survivors are able to achieve a good physical recovery, subtle dysfunction in other domains, such as cognition, often persists, and could affect return to work. However, reported estimates of return to work and factors affecting vocational outcome post-stroke vary greatly. Aims The aims of this systematic review were to determine the frequency of return to work at different time points after stroke and identify predictors of return to work. Summary of review Two electronic databases (Medline and Embase) were systematically searched for articles according to Preferred Reporting Items for Systematic Reviews and Meta Analyses guidelines. A total of 6473 records were screened, 68 were assessed for eligibility, and 29 met all inclusion criteria (working-age adults with stroke, return to work evaluated as an outcome, follow-up duration reported, and publication within the past 20 years). Return to work increased with time, with median frequency increasing from 41% between 0 and 6 months, 53% at 1 year, 56% at 1.5 years to 66% between 2 and 4 years post-stroke. Greater independence in activities of daily living, fewer neurological deficits, and better cognitive ability were the most common predictors of return to work. Conclusion This review highlights the need to examine return to work in relation to time from stroke and assess cognition in working age and young stroke survivors. The full range of factors affecting return to work has not yet been explored and further evaluations of return to work interventions are warranted. PMID- 29189109 TI - Monocentric experience of leadless pacing with focus on challenging cases for conventional pacemaker. AB - AIM: Leadless cardiac pacemaker has been developed to reduce complications related to cardiac pacing and is considered as an alternative to conventional pacemaker although safety and efficacy data in clinical practice are limited. The purpose of this study was to investigate the safety and efficacy profile of Micra Transcatheter Pacing System (TPS) used in daily clinical activity with a focus on challenging cases for conventional pacing. METHODS: A total of 66 patients (46 men, 79.1 +/- 9.7 years) having a Class I or II indication for ventricular pacing underwent a Micra TPS implant procedure. All patients were enrolled in a prospective registry. Follow-up visits were scheduled at discharge and after 1, 3, 6 and 12 months. RESULTS: Primary indication for pacing was third degree atrioventricular block (30.3%), sinus node dysfunction (21.2%) or permanent atrial fibrillation with bradycardia (45.5%). The device was successfully implanted in 65 patients (98.5%). During follow-up of 10.4 +/- 6.1 months (range 1-23 months), electrical measurements remained stable. Mean pacing capture threshold, pacing impedance and R-wave sensing were respectively 0.57 +/- 0.32 V, 580 +/- 103 Ohms, 10.62 +/- 4.36 mV at the last follow-up. One major (loss of function) and three minor adverse events occurred. Pericardial effusion, dislodgement, device related infection or pacemaker syndrome were not observed. Micra TPS implantation was straightforward for patients with congenital or acquired cardiac and/or vascular abnormalities, previous tricuspid surgery and after heart transplantation. CONCLUSION: Our experience confirms that implantation of Micra is safe and efficient in a real world population including patients who present a challenging condition for conventional pacing. PMID- 29189110 TI - Protecting safe abortion in humanitarian settings: overcoming legal and policy barriers. AB - Women and girls are increasingly the direct and targeted victims of armed conflict and studies show that they are disproportionately and differentially affected. However, humanitarian laws, policies, and protocols have yet to be meaningfully interpreted and adapted to respond to their specific needs, including to sexual and reproductive health services and rights. In particular, safe abortion services are routinely omitted from sexual and reproductive health services in humanitarian settings for a variety of reasons, including improper deference to national law, the disproportionate influence of restrictive funding policies, and the failure to treat abortion as medical care. However, properly construed, abortion services fall within the purview of the universal and non derogable protections granted under international humanitarian and human rights law. This commentary considers the protections of international humanitarian law and explains how abortion services fall within a category of protected medical care. It then outlines contemporary challenges affecting the realisation of these rights. Finally, it proposes a unification of current approaches through the use of international humanitarian law to ensure comprehensive care for those affected by armed conflict. PMID- 29189111 TI - Technical-environmental optimisation of the activated carbon production of an agroindustrial waste by means response surface and life cycle assessment. AB - In this study, a simultaneous optimisation of technical and environmental parameters for activated carbon production from soybean shells is presented. A 23 factorial design was developed to explore the performance of the technical responses yield and iodine number, and the single score of ReCiPe endpoint method, which was evaluated by means the life cycle assessment. The independent factors included in the design of experiments were the impregnation ratio, temperature, and time activation. Three quadratic equations were obtained and simultaneously optimised by maximisation of the overall desirability function. The principal results of the individual responses indicate that the iodine number is practically independent of the activation temperature in a range of 450 oC-650 oC; the yield is inversely proportional to activation time and exhibits minimum values between 500 oC-600 oC; and the environmental response single score presents the lowest value at a temperature and time activation of 450 oC and 30 min, respectively. The most polluting stage of activated carbon production from soybean shells production is the impregnation stage, mainly for the use of ZnCl2 as activating agent and the energy consumption. The simultaneous optimisation of the three responses indicates that the optimal activated carbon should be produced at 180 min, 650 oC, and an impregnation ratio of 1 g soybean shell g ZnCl2-1.

In this review, we focus on the OMVs produced by gram-negative bacteria. We provide an overview of the OMV structure, various factors regulating their production, and their role in modulating host immune response using a few representative examples. In light of the importance of the diverse cargoes carried by OMVs, we discuss the different modes of their entry into the host cell and advances in the high-throughput detection of these OMVs. A conspicuous application of OMVs lies in the field of vaccination; we discuss its success in immunization against human diseases such as pertussis, meningitis, shigellosis and aqua-farming endangering diseases like edwardsiellosis.

PMID- 29189116 TI - ScFv Improvement Approaches. AB - The most common recombinant antibody format is the single chain fragment variable (scFv) which it contains the complete antigen-binding domains of an intact antibody. ScFv fragments have found vast medical and non-medical applications. Several approaches have been employed to increase the affinity, avidity and structural stability related to these antibody fragments. Most approaches related to scFv improvement have been included in this review. PMID- 29189117 TI - In Silico Prediction of P-glycoprotein Binding: Insights from Molecular Docking Studies. AB - The P-glycoprotein is an efflux transporter that expels substances out of the cells and has an important impact in the pharmacokinetic and pharmacodynamic properties of drugs. The study of the interactions between ligands and the P glycoprotein has implications in the design of Central Nervous System drugs and their transport across the blood-brain barrier. Moreover, since the P glycoprotein is overexpressed in some types of cancers, the protein is responsible for expelling the drug therapies from the cells, and hence, for drug resistance. In this review we describe different P-glycoprotein binding sites reported for substrates, inhibitors and modulators, and focus on molecular docking studies that provide useful information about drugs and P-glycoprotein interactions. Docking in crystallized structures and homology models showed potential in the detection of the binding site and key residues responsible for ligand recognition. Moreover, virtual screening through molecular docking discriminates P-glycoprotein ligands from decoys. We also discuss challenges and limitations of molecular docking simulations applied to this particular protein. Computational structure-based approaches are very helpful in the study of novel ligands that interact with the P-glycoprotein and provide insights to understand the P-glycoprotein molecular mechanism of action. '. PMID- 29189118 TI - Metals and Parkinson's Disease: Mechanisms and Biochemical Processes. AB - Genetic background accounts for only 5 to 10% of the reported cases of Parkinson's disease (PD), while the remaining cases are of unknown etiology. It is believed that environmental factors may be involved in the causality of a large proportion of PD cases. Several PD genes are activated by xenobiotic exposure, and a link between pesticide exposure and PD has been demonstrated. Many epidemiological studies have shown an association between PD and exposure to metals such as mercury, lead, manganese, copper, iron, aluminum, bismuth, thallium, and zinc. This review explores the biological effects, the pathogenetic processes, genetic susceptibilities to metals as well as examining future strategies for PD treatment, such as chelation therapy. PMID- 29189119 TI - Journey of 2'-deoxy-2'-fluoro-5-methyl-1-beta-D-arabinofuranosyluracil (FMAU): from Antiviral Drug to PET Imaging Agent. AB - BACKGROUND: Developed as an antiviral drug in the 1960s and 1970s, the thymidine analogue 2'-deoxy-2'-fluoro-5-methyl-1-beta-D-arabinofuranosyluracil (FMAU) was translated to clinical application for treatment of herpes simplex virus infection. In phase I clinical trial of FMAU; however, patients experienced neurotoxicity at the pharmacological dose, and FMAU was withdrawn from the trial. More recently, FMAU has been developed as a tracer for positron emission tomography (PET) imaging in early detection of cancer through its binding to human thymidine kinase, which is upregulated in cancer cells. FMAU radiolabeled with 11C or 18F has been examined for PET imaging of tumor cell proliferation and DNA synthesis. Although many reports have been partially published on FMAU, systematic reviews outlining the historic development and imaging probe are lacking. This review is focused on the identification of kinases, the chemistry of FAMU and its application in cancer diagnosis and therapy assessment. OBJECTIVE: The aim of this study was to review the historic development of FMAU, from its synthetic development and antiviral activity studies to its radiolabeling and evaluate it as a PET imaging probe for the early detection of cancer and assessment of treatment response, including published reports on the clinical utility of 18F-FMAU. CONCLUSION: While FMAU was not successful as an antiviral agent, 18F-FMAU is a suitable radiotracer for early detection of cancer and assessment of response to therapy by PET. The process of clinical grade 18F FMAU production requires further improvement. 18F-FMAU has high potential for clinical application, but further extensive studies are needed to establish this tracer in the diagnosis of various cancers and assessment of their response to therapy. PMID- 29189120 TI - Critical Role of IL-8 Targeting in Gliomas. AB - BACKGROUND: Glioma is a heterogeneous, highly complicated central nervous system (CNS) tumor with uncertain mechanism of initiation and progression, resulting in an unfavorable outcome. An extended network of cytokines is recognized as a major regulator of glioma pathogenesis, either promoting or inhibiting glioma progression based on their type and specificity. Interleukin-8 (IL-8) has been revealed as a critical regulator of CNS function and development with participation in many CNS disorders including gliomas. OBJECTIVE: The aim of the present review is to address the role of IL-8 in glioma pathogenesis focusing on the implicated molecular pathways as well as on its potential targeting for glioma therapy. METHODS AND RESULTS: PubMed-Medline, SCOPUS, and Google Scholar databases were searched for pre-clinical and clinical studies related to IL-8 implication in gliomagenesis and IL-8 targeting strategies for gliomas. Literature data indicate that IL-8 participates in glioma angiogenesis and cell migration and it can serve as a potential biomarker, for early diagnosis, follow up and response to therapy. CONCLUSION: Several promising approaches that target directly or indirectly IL-8 effects in gliomas are currently in progress while more-in-depth studies are needed to validate its biomarker role and elucidate the underlying molecular mechanisms. PMID- 29189121 TI - The Development of Biologically Important Spirooxindoles as New Antimicrobial Agents. AB - BACKGROUND: Antibiotic resistance is one of the biggest threats to global health today, leading to higher medical costs and increased mortality. Because of the emergence and rapid spread of new resistance mechanisms globally, a growing number of infections are becoming harder to treat as the antibiotics used to treat them become less effective. Therefore, the development of new effective antimicrobial agents is still urgently needed. In last decades, a large number of structurally novel spirooxindoles have been synthesized mainly based on the ylide intermediates generated in situ and further assessed for their antimicrobial activity against different types of bacteria, leading to the discovery of some potent lead compounds with antimicrobial potentials. OBJECTIVE: The aim of this review to submarize recent advances on the synthesis, structure- activity relationship studies (SARs) and antimicrobial activity of spirooxindoles. METHODS: Peer-reviewed research work on spirooxindoles with antimicrobial activity were downloaded from bibliographic databases and analyzed based on their chemoptypes. RESULTS: 50 papers were retrieved from the literature databases, of which 20 papers described the synthesis and antimicrobial activity of spirooxindoles. CONCLUSION: This review highlights the importance of spirooxindoles as potential antimicrobial agents. The antimicrobial activity of spirooxindoles against different types of bacteria is less studied, mainly centering on primary antimicrobial assessment, some of these compounds have showed interesting antimicrobial activity. However, the current study is only limited to primary antimicrobial assessment, no detailed modes of action are investigated. PMID- 29189122 TI - Synthetic Polymer-based Electrospun Fibers: Biofunctionalization Strategies and Recent Advances in Tissue Engineering, Drug Delivery and Diagnostics. AB - BACKGROUND: Over the last decades, synthetic polymer-based electrospun nano/microfibers have emerged as potent materials in crucial biomedical applications such as tissue engineering, drug delivery and diagnostics. This is mainly attributed to versatility and reproducibility of the electrospinning (ES) process, as well as the high surface- to-volume ratio of the generated nanostructures. Appropriate functionalization with dedicated biomolecules (i.e. cell adhesive peptides, therapeutic molecules, bio-probes) is a critical requirement for the performances of such materials in their related application. METHODS: We report on the different chemical methodologies for preparing biofunctionalized synthetic polymer fibers, on the basis of two main approaches: biomolecule introduction after ES process (post-ES) and before ES (pre-ES). We then focused on the latest implications of such materials in areas of tissue engineering, drug delivery and diagnostics. RESULTS: This review describes the numerous immobilization strategies (either covalent or non-covalent) developed for designing biofunctionalized fibers, as well as their impact on their properties in dedicated application. The inputs of advanced conjugation tools ("clickable" chemistries, PEG linkers) for biofunctionalization are also highlighted. In the light of the literature, it appears that increasing research efforts are now devoted to multifunctional character and fiber combination with other materials (hydrogels, inorganic particles, microfluidic devices) for improved and tunable performances. CONCLUSION: Owing to flexibility and robustness of ES process as well as advances in conjugation and polymer/material engineering, high degree of control over biofunctionalization can now be achieved, to fit as best as possible the requirements of the targeted application. The performances reached up to now augur well for the future of such class of materials. PMID- 29189123 TI - Anti-Aging Drugs - Prospect of Longer Life? AB - BACKGROUND: Aging is a natural part of human life. However, recent discoveries indicate that pharmacological approaches used for the improvement and possibly, for the delay of the aging process, might shed a new light on this topic. This might obviously contribute to the extension of the active life of older people and maintenance of their quality of life, which could consequently reduce both social and economic burden of each country, especially the developed ones. OBJECTIVE: The purpose of this study is to explore pharmacological discoveries which may help to the delay or improvement of the aging process. More specifically, the authors focus on three anti-aging drugs candidates: metformin, rapamycin and resveratrol and one anti-aging component NAD+ precursors whose randomized control trials on animals have appeared to provide some efficacy in this respect and they seem to be promising in the aging process of human beings. METHODS: This was done by conducting a literature review of available sources describing the issue of aging process with special focus on those anti-aging drug candidates. RESULTS: The results of this study indicate that promising anti-aging candidates seem to be metformin, especially as far as cardiovascular or cancer mortality is concerned, and NAD+ precursors since they appear to promote better organ function, increased physical resistance, disease resistance and prolonged life expectancy. CONCLUSION: There is a call for more longitudinal clinical trials, which would prove the efficacy of the promising anti-aging drugs candidates in humans. PMID- 29189124 TI - Overview on Anticancer Drug Design and Development. AB - BACKGROUND: Many impediments of current anti-cancer therapies have urged scientists to discover new agents. As a result of growing spectrums of new targets and strategies and recent biological and biotechnological progresses, many anti-cancer agents such as monoclonal antibodies, small molecule tyrosine kinase inhibitors and epigenetic drugs have been reached to clinical trials. OBJECTIVES: This review helps to understand the rationale for the development of inhibitors against major targets such as cell growth, proliferation, survival, angiogenesis and recent targets such as proteasome, heat shock proteins, and epigenetics. METHODS: Recent approaches of the target-based anti-cancer drug developments were highlighted to giving some examples from approved agents. Many factors, such as metabolic change, hypoxia, cancer precursors and cancer resistant cells, and their effect on drug resistance mechanisms were discussed. The impacts of advanced computational techniques to identify targets of cancer and designing more selective inhibitors were explained. RESULTS: Contributions of recent techniques such as a network analysis, the precise modes of action and computational methodologies especially simulation of bio-molecular processes to clarify targets, mechanism actions and reasons of lack of efficacy of anti-cancer drugs have been explained. The relationship between the several mechanisms and molecular design strategies has been discussed. CONCLUSION: This review provides an overview of important targets and design strategies of anti-cancer drugs, advantages and disadvantages of these methods and evaluation of some currently used anticancer targets in clinical studies. PMID- 29189125 TI - Use of antibiotic loaded biomaterials for the management of bone prosthesis infections: rationale and limits. AB - BACKGROUND: Periprosthetic joint infection still represents a challenging issue for the orthopedic community. In the United States approximately a million joint arthroplasties are performed each year, with infection rates ranging from 1 to 2%: revisions has significant implications in health care costs and appropriate resources management. The use of locally applied antibiotics as a prophylaxis measure or as a component of the therapeutic approach in primary or revision surgery is finalized at eliminating any microorganism and strengthening the effectiveness of systemic therapy. OBJECTIVE: The present review of clinical and preclinical in vivo studies tried to identify advantages and limits of the materials used in the clinical orthopedic practice and discuss developed biomaterials, innovative therapeutic approaches or strategies to release antibiotics in the infected environment. METHOD: A systematic search was carried out by two independent observers in two databases (www.pubmed.com and www.scopus.com) in order to identify pre-clinical and clinical reports in the last 10 years. RESULTS: 71 papers were recognized eligible: 15 articles were clinical studies and 56 in vivo studies. CONCLUSION: Polymethylmethacrylate was the pioneer biomaterial used to manage infections after total joint replacement. Despite its widespread use, several issues still remain debated: the methods to combine materials and antibiotics, the choice of antibiotics, releasing kinetics and antibiotics efficacy. In the last years, the interest was directed towards the selection of different antibiotics, loaded in association of more than only one class, and biomaterials with special focus on delivery systems as implant surface coatings, hydrogels, ceramics, micro-carriers, microspheres or nanoparticles. PMID- 29189126 TI - Recent Advances for the Synthesis of Selenium-containing Small Molecules as Potent Antitumor Agents. AB - Selenium-containing small molecules have attracted considerable attention of chemical and medicinal researchers owing to their various biological activities, such as antitumor effects, cardiovascular protection, antibacterial or antiviral effects, immunoregulation and nerve protection, among which the most promising area is antineoplasm. In the past several decades, different kinds of organoselenium compounds, such as selenides, seleno(iso)cyanates, substituted selenoureas, selenious esters and Se-containing heterocycles have been reported as candidates of anti-cancer agents. Current reviews of Se-containing anticancer compounds mainly concerned about the investigation of their bioactivities, whereas, few attention has been addressed on their synthetic approaches. Herein, we summarized methodologies recently developed to synthesize organoselenium compounds with potent antineoplastic properties, which would be helpful for further design and synthesis of new bioactive Se-containing molecules with diverse structural features. PMID- 29189127 TI - Biosimilars: From Extrapolation into Off Label Use. AB - BACKGROUND: Biologic drugs have revolutionised the management of many inflammatory conditions. Patent expirations have stimulated development of highly similar but non-identical molecules, the biosimilars. Extrapolation of indications is a key concept in the development of biosimilars. However, this has been met with concerns around mechanisms of action, equivalence in efficacy and immunogenicity, which are reviewed in this article. METHODS: Narrative overview composed from literature search and the authors' experience. Literature search included Pubmed, Web of Science, and online document archives of the Food and Drug Administration and European Medicines Agency. RESULTS: The concepts of biosimilarity and extrapolation of indications are revisited. Concerns around extrapolation are exemplified using the biosimilar infliximab, CT-P13, focusing on mechanisms of action, immunogenicity and trial design. The opportunities and cautions for using biologics and biosimilars in unlicensed inflammatory conditions are reviewed. CONCLUSIONS: Biosimilars offer many potential opportunities in improving treatment access and increasing treatment options. The high cost associated with marketing approval means that many bio-originators may never become licenced for rarer inflammatory conditions, despite clinical efficacy. Biosimilars, with lower acquisition cost, may improve access for off label use of biologics in the management of these patients. They may also provide opportunities to explore off-label treatment of conditions where biologic therapy is less established. However, this potential advantage must be balanced with the awareness that off-label prescribing can potentially expose patients to risky and ineffective treatments. Post-marketing surveillance is critical to developing long-term evidence to provide assurances on efficacy as well as safety. PMID- 29189128 TI - Curcumin as an Adjunct Therapy and microRNA Modulator in Breast Cancer. AB - BACKGROUND: Pathogenesis of breast cancer is paralleled by distinct alterations in the expression profile of several microRNAs (miRNAs). Recent studies have shown that miRNAs can serve as diagnostic and prognostic markers, and also as therapeutic targets in breast cancer. Curcumin is a biologically active dietary polyphenol that has emerged with strong anti-tumor properties that are also documented in breast cancer. METHODS: A multi-database electronic search was performed to provide an overview of curcumin as an adjunct therapy and miRNA modulator in breast cancer and highlight the significance of observations for the treatment of cancer therapies. RESULTS: The putative anti-tumor properties of curcumin are mediated by diverse mechanisms including inhibition of cell proliferation, metastasis, migration, invasion and angiogenesis, and induction of G2/M cell cycle arrest, apoptosis and paraptosis. Recent evidence implies that curcumin can interact with several oncogenic and tumorsuppressive miRNAs involved in different stages of breast cancer. In this context, up-regulation of miR181b, miR-34a, miR-16, miR-15a and miR-146b-5p, and down-regulation of miR-19a and miR 19b have been shown following the treatment of several breast cancer cell lines with curcumin. These effects lead to the suppression of tumorigenesis and metastasis, and induction of apoptosis. CONCLUSION: Curcumin appears as an important miRNA modulator in breast cancer. However, further investigations are warranted to elucidate the impact of curcumin on miRNA transcriptome profile of breast cancer and the resulting impact of experimental models. PMID- 29189129 TI - FDG PET/CT Imaging in Diabetic Patients - A Special Emphasis on Imaging of Infection. AB - Nuclear Medicine (NM) imaging plays a major role in the assessment of infection and inflammation. Tracers, including single photon emitting radionuclides for Single Photon Emission Tomography (SPECT) and agents for positron emission tomography (PET), reflect primarily tissue and cellular function or metabolism. In the specific clinical setting of a patient with suspected infectious or inflammatory process, planar scintigraphy, SPECT or PET procedures are used to support a clinically suspected diagnosis. Integrating metabolic and anatomic information using a single SPECT/CT or PET/CT technique has substantially improved the diagnostic accuracy of these imaging tests and advanced the NM technology to be a significant and important tool in the field of infection and inflammation. Diabetes, one of the most prevalent diseases, has a direct relationship with the development of various infection related condition. Due to alterations in different metabolic pathways, imaging of the diabetic patient may be subject to specific pitfalls and obstacles which should be taken into consideration. This review aimed at describing the impact of diabetes and hyperglycemia on NM imaging, with an emphasis on FDGPET/ CT, in specific infectious conditions related to diabetes. PMID- 29189130 TI - Nuclear Medicine Imaging in Fever of Unknown Origin: The New Paradigm. AB - Fever of Unknown Origin, or FUO, is a challenging condition for patients and clinicians. In up to 50% of cases, no diagnosis is established. Patient workup begins with comprehensive history, physical examination and laboratory tests. Radionuclide imaging has been a second-line procedure. Gallium-67 citrate, which accumulates in infection, inflammation, and tumor, was for many years, the radionuclide test of choice in the workup of FUO. The 24-72 hours between injection and imaging, relatively high radiation dose to patients, and suboptimal image quality are significant disadvantages; imaging results are variable. Although labeled leukocyte imaging accurately localizes infection, infections cause only about 20%-40% of all FUO's. In most cases, this test is not helpful in identifying the source of the fever. Fluorine-18-fluorodeoxyglucose (FDG) uptake is related to cellular glucose metabolism. Increased FDG uptake is present in numerous hypermetabolic conditions, including tumor, infection, and noninfectious inflammation. FDG positron emission tomography (PET) and PET/computed tomography (CT) have rapidly assumed an increasingly important role in the diagnostic workup of patients with FUO. FDG is especially useful for localizing lesions and areas of interest for further evaluation. In contrast to gallium and labeled leukocyte imaging, FDG contributes useful information in children with FUO. Initially utilized as a second-line diagnostic tool in patients with FUO, recent data indicate that FDG contributes more diagnostically useful information than anatomic imaging like ultrasound and CT, which leads to earlier institution of appropriate therapy. These findings suggest that FDG imaging should be performed earlier, rather than later, in the diagnostic evaluation of the patient with FUO. PMID- 29189131 TI - Past and Future of Ga-citrate for Infection and Inflammation Imaging. AB - Both 67Ga and 68Ga-citrates are used to detect a wide spectrum of pathology consisting of various inflammatory, infectious and malignant conditions. Considering the now widespread availability and constantly increasing demand for PET/CT studies,68Ga-citrate is gaining ground in clinical settings and the added value of combined metabolic and anatomical imaging achieved by combining PET with Computed Tomography (CT) to PET/CT makes 68Ga-citrate particularly promising. Despite the tracer's non-specificity, it has demonstrated potential especially in the evaluation of various infectious and inflammatory skeletal- and lung conditions. In this review, we will focus on the indications and lessons learned from 67Ga, and present the current status for the use of 68Ga-citrate PET/CT in selected inflammation and infectious diseases based on the limited literature available. PMID- 29189132 TI - Polyphenols: Novel Signaling Pathways. AB - BACKGROUND: Cardiovascular disease (CVD) is currently the leading cause of death globally. The metabolic syndrome (MetS), a clustering of risk factors including hypertension, hyperglycemia, elevated low-density lipoprotein (LDL) cholesterol, reduced high-density lipoprotein (HDL) cholesterol and increased visceral adiposity, is a significant risk factor for the development of CVD. Non-alcoholic fatty liver disease (NAFLD), often referred to as the hepatic manifestation of MetS, is a constellation of progressive liver disorders closely linked to obesity, diabetes, and insulin resistance. NAFLD initially presents as relatively benign, non-progressive hepatic steatosis, but it may, in certain individuals, progress to nonalcoholic steatohepatitis, fibrosis, cirrhosis, or hepatocellular carcinoma. Currently, there are no validated treatments for NAFLD. Polyphenols are important bioactive dietary compounds and may represent a natural complementary and integrative therapy for the treatment of CVDassociated risk factors, including elevated serum cholesterol and triglyceride levels, as well as NAFLD. Understanding their molecular mechanisms of action is important in the design of future human intervention studies. METHODS: Several studies utilizing in vitro and in vivo models have helped to identify underlying molecular mechanisms of action of polyphenols. RESULTS: This review will highlight recent advances regarding the molecular actions of dietary procyanidins, with a special focus on those originating from procyanidin-rich grape seed extracts, with a focus on the signaling pathways utilized to exert beneficial metabolic effects. CONCLUSION: Modulation of nuclear receptor activity and histone deacetylase inhibition has been identified as underlying mechanisms contributing to procyanidin-mediated amelioration of dyslipidemia and steatosis. PMID- 29189133 TI - Risk Assessment and Monitoring of Antibody Responses to Biosimilars in Chronic Inflammatory Diseases. AB - The expiry of the patent of several leading biological medicinal products has led to a surge in the development of 'biosimilar' products. However, in contrast to generic small-molecule medicines, biosimilars are not identical to their reference medicinal products. Full comparability in quality as well as in preclinical and clinical issues is required to register a biosimilar. The potential to induce antidrug antibodies after treatment with biological medicinal products is a safety issue that is an important consideration in the development of biosimilars and a critical aspect of regulatory filings. Regulatory authorities in the European Union require antidrug antibody responses to be evaluated and to be approached from a safety perspective: the higher the potential of immunogenicity to adversely affect a patient's health, the more diligently one should clarify the immunogenicity of the product. So far, however, no specific recommendations were given on a method for risk assessment or on the extent of the requisite antidrug antibody characterization. In this review, we will discuss the current state of knowledge on biosimilar products of infliximab, adalimumab and etanercept and present risk level-based schemes for the investigations of antidrug antibodies in non-clinical, clinical and pharmacovigilance studies. PMID- 29189134 TI - The Economic Impact of Biosimilars on Chronic Immune-Mediated Inflammatory Diseases. AB - BACKGROUND: Biological drugs represent highly effective but costly treatments for chronic immunemediated inflammatory diseases posing substantial burden on health care budgets. Introduction of biosimilars since 2013 has brought forward the potential of market competition, and as a societal benefit, the hope of increased access at a lower cost. OBJECTIVE: We aim to provide a descriptive review on economic aspects and market changes related to the introduction of biosimilar drugs. METHOD: Our focus is on chronic immune-mediated inflammatory conditions in rheumatology, gastroenterology and dermatology. Based on available literature data, we discuss the determinants of access to biological treatment, summarize the available health economic evidences with special focus on cost-utility and budget impact analyses. Market penetration of biosimilars and their overall impact on biological markets are analyzed. RESULTS: Biosimilar markets are country specific due to differences in the regulatory and reimbursement systems. Cost-utility analyses suggest, that given the lower price of biosimilars, formerly established biological treatment sequence practices and the eligibility criteria for biological treatment deserve reconsideration. Budget impact analyses forecasted significant budget savings in various diagnoses and countries, providing opportunity for the treatment of more patients. CONCLUSION: Biosimilars may contribute to better patient-access and provide savings to governments. To increase their acceptability, further clinical evidences and real world experiences are needed, as well as education of physicians and patients. The high biosimilar penetration rates in Norway, Denmark and Poland suggest that policies which support interchanging from the reference product may be important drivers of biosimilar uptake. PMID- 29189135 TI - The Experience with Biosimilars of Infliximab in Rheumatic Diseases. AB - BACKGROUND: Infliximab biosimilars are the first biosimilars of monoclonal antibodies approved by the main regulatory agencies. Up to the present day, two infliximab biosimilars have been approved: CT-P13 (Celltrion), and SB2 (Biogen), but other companies have been developing candidate infliximab biosimilars that are on clinical trials: PF 06438179 (Pfizer), the ABP710 (bioCentury/Amgen) the BCD055 (JSC Biocad Russica) and BOW015 (Epirus). METHODS: We have made a literature search in MedLine database using the key words [Infliximab] and [biosimilars] and [rheumatic diseases] and [rheumatisms]. We have also made a search in the clinicaltrials.org website. CONCLUSIONS: Clinical data published so far have provided important evidence on long-term efficacy and safety, immunogenicity and switching, supporting the use of CT-P13 and SB2 for the treatment of rheumatic diseases. In addition, the European experience has proved the economic advantages of the incorporation of infliximab biosimilars in clinical practice. Despite the widespread use of infliximab biosimilars there is still a lack of data regarding interchangeability between reference products and biosimilars. PMID- 29189136 TI - The Role of Biosimilars in Patient Access to Therapeutic Antibodies for Immune Mediated Inflammatory Diseases. AB - BACKGROUND: Biosimilars have the potential to create competition, lower costs, and increase patient access to biological medications. However, biological medications are sensitive to their manufacturing processes and difficult to precisely characterize, leading to questions about substitution and interchangeability among products. METHODS: This article reviews the role of biosimilars in patient access to therapeutic antibodies. RESULTS: Although pathways for the approval of biosimilars have been developed, important issues remain unresolved. Interchangeability, or the designation of one medicine as clinically similar to and/or substitutable for another, is specified in some countries but restricted or awaiting policy resolution in others. Non-medical switching, or the switching among biological medications to select a less expensive product, for reasons unrelated to patient health and safety, is controversial because of the potential for complications related to repeated switching (e.g., immunogenicity and loss of therapeutic effect), and transfer of prescribing responsibility for patient medications from the physician to the insurance company. Although biosimilars have different names in different countries, the World Health Organization (WHO) calls for nomenclature that incorporates the international nonproprietary name of the original biological medication followed by a distinguishing suffix qualifier. Naming consistency across countries seems sensible, and adoption of the WHO recommended suffix would greatly simplify pharmacovigilance. CONCLUSIONS: Support for the WHO proposal is advised by numerous stakeholders, and resolution of the remaining outstanding issues is urged so that patients and physicians can safely access biosimilars. PMID- 29189137 TI - Platform for Lipid Based Nanocarriers' Formulation Components and their Potential Effects: A Literature Review. AB - BACKGROUND: Lipid based nanocarriers have gained recently enormous interest for pharmaceutical application. They have the potential to provide controlled drug release and to target the drug to a specific area. In addition, lipid based nanocarriers can improve the bioavailability of drugs suffering from high hepatic first-pass metabolism, by enhancing their transport via the lymphatic system. The main components of lipid based nanocarriers are lipids and surfactants. Both have great influence on the prepared lipid based systems characteristics. The criteria for their selection are much related to physicochemical properties of the drug and the required administration route. This work gives an overview on the effect of both the type and amount of lipids and surfactants used in the manufacture of lipid based nanocarriers on their behavior and characteristics. CONCLUSION: Recent studies revealed that the properties of the final product including; particle size, homogeneity, drug loading capacity, zeta potential, drug release profile, stability, permeability, pharmacokinetic properties, crystallinity and cytotoxicity, may be significantly influenced not only by the type but also the amount of the lipids and/or surfactants included in the formulation of the lipid based nanocarriers. PMID- 29189139 TI - Lipid nanoparticles for the delivery of active natural medicines. AB - BACKGROUND: Thousands of bioactive compounds are identified and isolated from the medicinal plants every year, of which many possess significant health benefits. However, the overwhelming majority of entities suffer from poor water solubility and membrane permeability that impedes them approaching the clinical stage. METHODS: Lipid nanoparticles have shown to be a versatile platform for advanced delivery of various therapeuticals, including the oral, topical and systemic routes. Lipid nanoparticles are able to significantly improve the oral bioavailability, pharmacokinetic profile, skin permeability, and ocular residence time of drugs, demonstrating considerable potential in pharmaceutical or medical practice. RESULTS: This article profoundly reviews important applications of lipid nanoparticles in active natural medicines. Special concerns focus on solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) for their training in the oral, intravenous, percutaneous and ocular drug delivery. CONCLUSION: The survey shows that lipid nanoparticles are promising vehicles for the delivery of various natural actives and may address some intractable problems associated with delivery thereof. PMID- 29189138 TI - Intranasal lipid nanoparticles for the treatment of neurodegenerative diseases. AB - BACKGROUND: Current treatments for neurodegenerative diseases are challenging, due to the absence of full effective medicines. One of the major problems associated to these is the occurrence of non-targeting events, which leads to adverse effects and requires frequent dose administration. METHODS: Researches have been performed to develop new drug delivery systems administrated by alternative routes. For example, the direct nose-to-brain delivery of drugs by means of lipid nanoparticles, such as solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC), have been showing promising results. RESULTS: Among the advantages of intranasal administration is the avoidance of passing the blood-brain barrier (BBB) to reach the central nervous system (CNS), allowing the direct delivery of drugs to the brain by a non-invasive way, minimizing systemic exposure and prolonging residence time. This review article discusses the advantages of using SLN and NLC for direct nose-to-brain drug delivery. A brief reference to other lipid-based carriers (liposomes, nanoemulsions and microemulsions) is also provided. CONCLUSION: The benefits of using SLN and NLC for improve nasal drug delivery have been demonstrated by in vitro, ex vivo and in vivo experiments. However, more in vivo animal studies are needed for advance to human clinical trials and reach clinics. PMID- 29189140 TI - Polyphenols Effect on Circulating Lipids and Lipoproteins: From Biochemistry to Clinical Evidence. AB - BACKGROUND: Polyphenols are a family of natural antioxidants that in recent years have been studied and tested for their potential benefits towards cardiovascular diseases. OBJECTIVE: The aim of this review is to focus the attention on the presumed lipid-lowering and atheroprotective effects of polyphenols, administered either as individual molecules (nutritional supplements) and as functional foods, on the basis of the evidence coming from randomized controlled trials (RCTs) and their meta-analyses. METHOD: A search strategy was conducted to identify studies in PubMed (January 1980 to September 2016); in particular, we have included human clinical trials, reviews and meta-analyses when they offered suitable insights and elucidations regarding the action of polyphenols on lipid profile and cardiovascular disease risk. RESULTS: Literature data on polyphenols suggest that they potentially could exert an effect on lipid profile, especially by reducing the oxidation of LDL-C. Polyphenols from cocoa, grape, green tea, berries and soy are the ones that have shown more clinically relevant effect. However, quantitative data on cholesterol reduction are still unclear and often conflicting. CONCLUSION: Polyphenols, if taken in adequate dosages, can exert in some cases a positive effect on the prevention of cardiovascular risk and lipid oxidation, despite an unclear effect on lipid levels.

AB - BACKGROUND: In Physiologically Based Pharmacokinetic (PBPK) models, the most important input parameter is tissue-to-plasma partition coefficient (Kp). Over the years, several empirical methods have been developed to predict Kp in animals. OBJECTIVES: The objective of this study was to propose two allometric methods to predict Kp from experimentally determined in vivo volume of distribution at steady state (Vss). METHOD: In one method, Vss was allometrically predicted (using a fixed exponent 1.0 or 0.8) in a given tissue of the rat and then Kp was predicted for that tissue. In another method, an allometric plot (Kp versus Vss) was developed to predict Kp in a tissue of the rat. In total, Kp values were predicted for 46 drugs and 338 tissues. The predicted Kp values by the proposed two methods were compared with the experimentally determined Kp values as well as empirically predicted Kp values by other investigators. RESULTS: Comparison of the predicted Kp values by the two proposed methods with experimentally determined Kp values indicated that 67-72% of the predicted Kp values were within two-fold prediction error. The predictive power or accuracy of method 1 (when taken all tissues and all classes of drugs into account) was 19%, 35%, 14%, 35%, 14%, and 13% better than the methods proposed by Arundel, Berezhkovskiy, Jansson et al., Poulin et al., Poulin- Theil, and Rodgers et al. respectively. CONCLUSION: The proposed two allometric methods are slightly more accurate than other empirical methods in their predictive performance for the prediction of tissue Kp values for acidic, weak bases and neutral drugs.

AB - BACKGROUND: Hair has been suggested since the middle of the 90's to be a suitable matrix to document repetitive exposure to cannabis. Because it is possible to detect Delta9-tetrahydrocannabinol (THC), cannabinol (CBN) and cannabidiol (CBD) in cannabis smoke, the identification of the metabolite, 11-nor-Delta9 tetrahydrocannabinol carboxylic acid (THC-COOH) has been considered to allow the discrimination of active use. OBJECTIVE: Although the identification of an active compound in a child's hair shows contamination of the local environment, it is a challenge to discriminate between hair incorporation after ingestion or inhalation and environmental external deposition from dust, smoke, or even contaminated surfaces by hand contact. However, it is particularly important in case of children to correctly interpret the data, particularly for a realistic assessment of the health risk. We present here a series of hair tests for cannabis where the interpretation was almost impossible to establish. METHOD: Hair specimens were collected during the autopsy of the 12 children, aged 2 to 24 months, either deceased from shaken baby syndrome (SBS, n=4), mechanic asphyxia (MA, n=1) or sudden infant death (SID, n=7) during January 2015 to April 2017. After decontamination, the hair specimens were tested for THC, CBN and CBD and THC-COOH. The whole length of hair was submitted to analysis. RESULTS: The amount of hair from children can be as low as 8 mg. This may affect the limit of quantitation of all drugs, but particularly THC-COOH. Eight from twelve hair tests were positive for cannabis markers, i.e. THC (39 to 1890 pg/mg, n=8), CBN (< 5 to 1300 pg/mg n=8), CBD (10 to 2300 pg/mg, n=8) and THC-COOH (not detected to < 0.5 pg/mg, n=5). In 4 cases from 8 positive findings, it was not possible to test for THC-COOH (not enough material). CONCLUSION: Establishing a window of detection when testing for drugs in young children is a very complicated task. Hair from children is finer and more porous in comparison with adult (the risk of contamination from sweat and environmental smoke is higher than in adults). The final interpretation of cannabinoid findings in the children's hair is very complicated as this can result from in utero exposure (although none of the mother admitted cannabis use during pregnancy), oral cannabis administration by the parents to achieve sedation, close contact to cannabis consumers (hands, bedding, dishes) and inhalation of side-stream smoke. Over-interpreting cannabis findings in hair can have very serious legal implication in child protection cases. Practicing scientists have the responsibility to inform the child protection authorities, courts, etc. about these limitations. PMID- 29189143 TI - Retrospective Demonstration of 25I-NBOMe Acute Poisoning Using Hair Analysis. AB - BACKGROUND: The abuse of new psychoactive substances or NPS has been dramatically increasing all around the world since the last half of the year 2000 and has become a serious public health problem. NPS are a challenge for the worldwide forensic community due to the difficulties to accurately document the cases. The N-benzylmethoxy (NBOMe) group is a new class of hallucinogenic designer drugs and has gained importance in recent years. 25I-NBOMe (2-(4-iodo-2,5-dimethoxyphenyl) N-[(2-methoxyphenyl)- methyl]ethanamine) is an analog of the 2C series of psychedelic phenethylamine drugs that contain an N-methoxybenzyl substituent, which significantly affects their pharmacological activities. It is a potent agonist of 5-HTA receptors and a severe hallucinogenic drug, with numerous irreversible psychedelic effects which can last from 5 to 10 hours. It is consumed most often in the form of drops or blotters by the transmucosal, sublingual or intranasal routes. The active dosage is very low, supposed to be less than 100 ug. The literature is poor in reporting cases where 25I-NBOMe was identified. Only very few clinical cases of over dosages were published, suggesting a low prevalence of this compound. METHODS: We present a retrospective demonstration of 25I-NBOMe acute poisoning with dramatic outcome, using hair analysis. Two hair strands, measuring 9.5 cm, were collected 6.5 months after drug consumption during a forensic clinical evaluation of brain dysfunctions after cardiorespiratory arrest and were analyzed by ultra-high performance liquid chromatography system coupled to a tandem mass spectrometry (UPLC-MS/MS) and using two specific transitions: m/z 428.1 > 121.2 (quantification) and 428.1 > 90.6 (confirmation). Hair strands were segmented to determine the historic pattern of drug use and differentiate a single exposure from a chronic exposure. The hair test result for 25I-NBOMe was the following: not detected (0-2 cm), not detected (2-4 cm), 1.0 pg/mg (4-6 cm), 4.9 pg/mg (6-8 cm) and not detected (8-9.5 cm). RESULT: The result of the segment 6-8 cm coincides with the date of consumption (calculated with a hair growth rate at 1 cm/month) and the low concentration detected in the segment 4-6 cm probably corresponds to the contribution of dormant hair. The toxicological significance of the measured concentrations is difficult to determine because this is the first case dealing with hair analysis for 25I-NBOMe. CONCLUSION: The use of hair analysis for NPS is still at the initial stages. In particular, little is known about the incorporation into the keratin matrix after intake and the correlation between dosage frequency of use, and hair concentrations. Under these circumstances, NPS hair analysis should be cautiously interpreted by experienced forensic toxicologist. PMID- 29189144 TI - Therapeutic Use of Delta9-THC and Cannabidiol: Evaluation of a New Extraction Procedure for the Preparation of Cannabis-based Olive Oil. AB - BACKGROUND: Since 2013 Cannabis-based preparations, containing the two main cannabinoids of interest, Delta9-tetrahydrocannabinol (THC), and cannabidiol (CBD), can be used for therapeutic purposes, such as palliative care, neurodegenerative disorder treatment and other therapies. The preparations may consist of a drug partition in sachets, capsules or through the extraction in certified olive oil. OBJECTIVE: The aims of the study were: a) to develop and validate a new liquid chromatographictandem mass spectrometric (LC-MS/MS) method for the identification and quantification of THC and CBD in olive oil; b) to evaluate the extraction efficiency and reproducibility of a new commercial extractor on the market. METHODS: The olive oil was simply diluted three consecutive times, using organic solvents with increasing polarity index (n hexane -> isopropanol -> methanol). The sample was then directly injected into LC MS/MS system, operating in Multiple Reaction Monitoring Mode, in positive polarization. The method was then fully validated. RESULTS: The method assessed to be linear over the range 0.1-10 ng/uL for both THC and CBD. Imprecision and accuracy were within 12.2% and 16.9% respectively; matrix effects proved to be negligible; THC concentration in oil is stable up to two months at room temperature, whenever kept in the dark. CBD provided a degradation of 30% within ten weeks. The method was then applied to olive oil after sample preparation, in order to evaluate the efficiency of extraction of a new generation instrument. Temperature of extraction is the most relevant factor to be optimized. Indeed, a difference of 2 degrees C (from 94.5 degrees C to 96.5 degrees C, the highest temperature reached in the experiments) of the heating phase, increases the percentage of extraction from 54.2% to 64.0% for THC and from 58.2% to 67.0% for CBD. The amount of THC acid and CBD acid that are decarboxylated during the procedure must be check out in the future. CONCLUSION: The developed method was simple and fast. The extraction procedure proved to be highly reproducible and applicable routinely to cannabis preparations.

PMID- 29189146 TI - Transforming Growth Factor Beta Type I Role in Neurodegeneration: Implications for Alzheimer's Disease. AB - Alzheimer's disease is a neurodegenerative condition affecting millions of people worldwide. Alzheimer's symptoms include memory loss and cognitive decline. Pathologically, the hallmarks of Alzheimer's are the presence of Amyloid beta plaques, neurofibrillary tangles, and neuronal loss. Unfortunately, no cure is presently available and current treatments are only symptomatic. Transforming growth factor beta type I (TGF-beta1) is a trophic factor involved in neuronal development and synaptic plasticity. Impairment of TGF-beta1 signaling is associated with exacerbated Abeta deposition and neurofibrillary tangle formation, which increases neurodegeneration. Aging and chronic inflammation reduce the canonical TGF-beta1/Smad signaling, facilitating cytotoxic activation of microglia and microgliamediated neurodegeneration This review gathers together evidence for a neuroprotective role of TGF-beta in Alzheimer's disease. Restoring TGF-beta1 signaling impairment may be a new pharmacological strategy Alzheimer's treatment. PMID- 29189147 TI - Disrupting Acetyl-lysine Interactions: Recent Advance in the Development of BET Inhibitors. AB - BACKGROUND: Histone acetylation is an essential approach of post-translational modification (PTM) and a significant component of epigenetic regulation that is mediated by Bromodomainscontaining protein (BRDs). In recent years, many researchers have found that a variety of malignancy, inflammatory and other diseases occurrences and developments are associated with BRD4 expression disorders or dysfunction. Meanwhile, many inhibitors of the extra-terminal (BET) family have been reported in many papers. OBJECTIVE: This review summarized those newly found BET inhibitors, their mechanism of action and bioactivity. Secondly, those compounds were mainly classified based on their structures and their structure-activity relationship information was discussed. Beyond that, every compound's design strategy was pointed out. RESULTS AND CONCLUSION: Herein, the recent advances reported were reviewed for discovering more excellent small molecule inhibitors. Currently, in addition to compound 4, compounds 7, 22 and 90, have also been into the clinical trial stage. In the view of the outstanding performance of BET inhibitors in anti-tumor, anti-inflammatory and anti-drug resistance, we believe that more and more BET inhibitors will become the new epigenetic therapy for cancer, inflammation and autoimmune disease in clinical practice in the near future. PMID- 29189148 TI - Identification of Novel Ligands for Therapeutic Lipopeptides: Daptomycin, Surfactin and Polymyxin. AB - BACKGROUND: Due to increase in antibiotic-resistance among pathogens, there is a need for potent and safe drugs. An alternative to antibiotics is lipopeptides which are produced as a secondary metabolite by many microorganisms. They exhibit broad-spectrum activities against pathogens along with anticancer properties. Among various lipopeptides produced by microorganisms, daptomycin, surfactin, and polymyxin have gained popularity as medicines but their mechanism of action is not described properly. In silico drug design of these lipopeptides becomes a challenge due to their complex structures. In order to initiate a physiological response, specific agonists (ligands) of their receptor (lipopeptide) must be identified. OBJECTIVE: The objective of this study was molecular docking of three lipopeptides, daptomycin, surfactin and polymyxin, with their ligands as a means of drug design. METHOD: Schrodinger software was used for molecular docking of lipopeptides with their corresponding ligands whereas the ligand search was done using RCSB. Once the ligands were identified, they were docked with their corresponding lipopeptide. Docking score and glide energy were used as the parameters to test docking. RESULTS: All four of the identified ligands were found to dock with daptomycin, whereas for both surfactin and polymyxin one out of two ligands docked with the lipopeptides. CONCLUSION: The knowledge of the docking sites and docking characteristics of the lipopeptide mentioned in the paper with the ligands can provide advantages of high speed and reliability, reduced costs on chemicals and experiments and the ethical issues concerned with the use of animal models for screening of drug toxicity. PMID- 29189149 TI - Theranostic Aspects: Treatment of Cancer by Nanotechnology. AB - Theranostic agents or theranostic imaging as its name suggests is a combination of two terms-'diagnosis' & 'therapy'. Efforts are being made to combine both the terms into clinical formulations. This theranostic imaging is found to be very much significant to complex diseases like cancer and proliferative tumors especially because accurate photocopy for every tumor can be obtained by genomic and proteomic profiling and using such informations in theranostic agents can be constructed or modeled in such a way that it is specific in its action and selective towards the cancer cells only, without causing any adverse effects on the normal tissue cells. By means of nanoplatforms, we can conveniently deliver cancer cell specific targeting ligand or peptide inside the human body. Primary delivery approach comprises of nanoparticles, liposomes, dendrimers, prodrugs, polymersomes, carbon nanotubes and polymeric micelles. Theranostic agents, i.e., therapeutic and diagnostic agents can be physically bound or else they can be bound with polymers which are exclusively designed and this together forms nanocarriers. Hence, the review highlights the advances of nanotechnology that has given us a platform for cancer detection and treatment. PMID- 29189150 TI - Natural Bioactive New Withanolides.

In 1871, the German ophthalmologist Theodor Leber was the first to describe the clinical characteristics of his namesake disease, and through unremitting efforts over the past 100 years, researchers have continued to increase their understanding of LHON. In recent years, using gene therapy, several groups have obtained breakthroughs in the treatment of the disease. CONCLUSION: In this article, we will review the challenging journey that researchers faced towards our current understanding of LHON, and describe the transition of gene therapy research for LHON from the bench to bedside. PMID- 29189154 TI - Brain Targeted Intranasal Zaleplon Nano-emulsion: In-Vitro Characterization and Assessment of Gamma Aminobutyric Acid Levels in Rabbits' Brain and Plasma at Low and High Doses. AB - BACKGROUND: Zaleplon is a pyrazolopyrimidin derivative hypnotic drug indicated for the short-term management of insomnia. Zaleplon belongs to Class II drugs, according to the biopharmaceutical classification system (BCS), showing poor solubility and high permeability. It undergoes extensive first-pass hepatic metabolism after oral absorption, with only 30% of Zaleplon being systemically available. It is available in tablet form which is unable to overcome the previous problems. OBJECTIVE: The aim of this study is to enhance solubility and bioavailability via utilizing nanotechnology in the formulation of intranasal Zaleplon nano-emulsion (ZP-NE) to bypass the barriers and deliver an effective therapy to the brain. METHOD: Screening studies were carried out wherein the solubility of zaleplon in various oils, surfactants( S) and co-surfactants(CoS) were estimated. Pseudo-ternary phase diagrams were constructed and various nano emulsion formulations were prepared. These formulations were subjected to thermodynamic stability, in-vitro characterization, histopathological studies and assessment of the gamma aminobutyric acid (GABA) level in plasma and brain in rabbits compared to the market product (Sleep aid(r)). RESULTS: Stable NEs were successfully developed with a particle size range of 44.6+/-3.4 to 136.9+/-1.6 nm. CONCLUSION: A NE composed of 10% Miglyol(r) 812, 40% Cremophor(r) RH40 40%Transcutol(r) HP and 10% water successfully enhanced the bioavailability and brain targeting in the rabbits, showing a three to four folds increase than the marketed product. PMID- 29189153 TI - Antiviral Effects of Saffron and its Major Ingredients. AB - BACKGROUND: The lack of an effective vaccine against viral infections, toxicity of the synthetic anti-viral drugs and the generation of resistant viral strains led to discover novel inhibitors. Recently, saffron and its compounds were used to treat different pathological conditions. METHOD: In this study, we tested the anti-HSV-1 and anti-HIV-1 activities of Iranian saffron extract and its major ingredients including crocin and picrocrocin as well as cytotoxicity in vitro. The data showed that the aqueous saffron extract was not active against HIV-1 and HSV-1 virions at certain doses (i.e., a mild activity), but crocin and picrocrocin indicated significant anti-HSV-1 and also anti-HIV-1 activities. Crocin inhibited the HSV replication at before and after entry of virions into Vero cells. Indeed, crocin carotenoid suppressed HSV penetration in the target cells as well as disturbed virus replication after entry into the cells. Picrocrocin was also effective for inhibiting virus entry and also its replication. RESULTS: This monoterpen aldehyde showed higher anti-HSV effects after virus penetrating in the cells. Generally, these sugar-containing compounds extracted from saffron showed to be effective antiherpetic drug candidates. CONCLUSION: The recent study is the first report suggesting antiviral activities for saffron extract and its major ingredients. Crocin and picrocrocin could be a promising anti-HSV and anti-HIV agent for herbal therapy against viral infections. PMID- 29189155 TI - Fabrication and Characterization of Timolol Maleate and Brinzolamide Loaded Nanostructured Lipid Carrier System for Ocular Drug Delivery. AB - BACKGROUND: The combination of timolol maleate (TM) and brinzolamide (BRZ) has potential therapeutic prospects for treating glaucoma. However, the conventional formulation of TM and BRZ exhibits sub optimal therapeutic effects attributable to the poor ocular bioavailability of these drugs. OBJECTIVE: Therefore, the aim of the present study was to design and evaluate TM and BRZ loaded nanostructured lipid carrier (NLC) to enhance the bioavailabilities, permeation and precorneal residence time of these drugs that would result in efficacious treatment of glaucoma. METHODS: In this study, combination of drugs with different characteristic properties was loaded in NLC. The dual drugs loaded NLC was prepared by melt emulsification technique and evaluated for characteristic properties such as particle size (PS), polydispersity index (PDI), entrapment efficiency (EE) and drug loading (DL), in vitro drug release and ex vivo drug penetration studies. RESULTS: The PS and PDI of optimized NLC formulation were found to be 110.36 +/-0.47 nm and 0.24 +/- 0.00 respectively. The EE and DL of optimized NLC formulation were found to be 77.12 +/- 0.64 % and 0.360 +/- 0.01 % for TM respectively; whereas, 70.73+/-0.64 % and 0.71 +/- 0.02 %for BRZ respectively. In vitro drug release studies showed a comparable initial rapid release of around 34 +/- 2.90 % for TM and 38 +/- 3.10 % for BRZ in the first 5 h followed by sustained drug release around 72.29 +/- 5.90 % for TM and 70.08 +/- 6.40 % for BRZ until last 24 h. Ex vivo drug penetration studies showed about 33.47 +/- 2.80 % of TM and 36.20 +/- 2.80 % of BRZ permeated in the first 5 h followed by 72.30 +/- 6.40% of TM and 67.69 +/- 6.500 % of BRZ until 24 h. There was remarkable enhancement in the release pattern and permeation of both the drugs from NLC as compared to that from their suspension. CONCLUSION: With dextrous optimization of dose and excipients concentration, the dual drugs with different characteristic properties can be successfully loaded in NLC formulation. PMID- 29189156 TI - Post-stroke Constraint-induced Movement Therapy Increases Functional Recovery, Angiogenesis, and Neurogenesis with Enhanced Expression of HIF-1alpha and VEGF. AB - BACKGROUND: Constraint-Induced Movement Therapy (CIMT) is one efficient approach to improve functional recovery after ischemic stroke. The underlying molecular mechanism remains unclear. In the current study, we investigated the effects of CIMT on angiogenesis and neurogenesis. To start linking our findings to molecular mediators, we further examined the expression of Hypoxia-Inducible Factor-1alpha (HIF-1alpha), Factor Inhibiting HIF-1 (FIH-1) and Vascular Endothelial Growth Factor (VEGF). METHODS: Rats were randomly assigned into three groups: a Middle Cerebral Artery Occlusion group (MCAO), a therapeutic group (CIMT+MCAO), and a sham middle cerebral artery occlusion group (Sham). Seven days after surgery, a plaster cast was placed around the unimpaired upper limb of the rats in the CIMT+MCAO group for 14 days. CIMT was performed on a horizontal ladder. Neurobehavioral consequences were evaluated using the Open-Field Test (OFT) and the Foot-Fault Test (FFT). The number of new neurons, the length of vessels as well as the expression of HIF-1alpha, FIH-1, and VEGF were examined before and after 14 days of CIMT. RESULTS: The CIMT+MCAO group showed a significant increase in the total length of microvessels and increased number of Bromodeoxyuridine+ (BrdU+)/NeuN+ double-labeled cells. These changes were correlated with an increase in HIF-1alpha and VEGF expressions and a decrease in FIH-1expression. FFT showed that the CIMT+MCAO group exhibited marked improvement in neurobehavioral outcome when compared to the MCAO group. Adverse effects on total activities or anxiety were not observed using open field analysis. CONCLUSION: CIMT-induced neuroprotection and functional recovery following cerebral ischemia were possibly mediated by an increase in endogenous HIF-1alpha and VEGF expression with subsequent neurogenesis and angiogenesis.

PMID- 29189158 TI - Cancer Targeted Therapy Strategy: The Pathologist's Perspectives. AB - The effectiveness of new personalized treatment procedures in oncology is based on the fact that certain tumors exhibit specific molecular features. More in detail, neoplastic tissues of patients should display a specific biomarker, most often a specific genetic alteration and/or under/overexpression of a definite protein, that could be the target of its respective drug. Immunohistochemical and molecular analyses, which usually include examination of nucleic acids from either tissues or fluids, are common tests to define the status of a tumor. This review focuses on the pathologist's role in carefully controlling pre- analytic procedures and standard operating procedures that are a crucial prerequisite to reach reliable and reproducible results. Six paradigmatic applications of targeted therapy, for which pathological diagnosis plays a fundamental role, are summarized. Traditional and next-generation sequencing are also addressed from the pathologist's perspective as well as the importance pathologists have in this shift to more accurate definition of disease risk and prognostication of therapy response in the personalized medicine era.

PMID- 29189160 TI - Role of Glioma-associated GLI1 Oncogene in Carcinogenesis and Cancertargeted Therapy. AB - Glioma-associated oncogenes (GLIs) are zinc finger protein family members and downstream regulatory factors of the classic Hedgehog (Hh) signaling pathway. GLI proteins influence the growth and development of organisms and aid in tissue repair. However, aberrant expression of the GLI family member GLI1 promotes carcinogenesis by inducing epithelial-mesenchymal transition (EMT), angiogenesis, and other signaling pathways. Overexpression of GLI1 is thought to be an indicator of poor prognosis as well as a potential therapeutic target for cancers. GLI inhibitors such as zerumbone, GANT61, resveratrol, and cyclopamine depress the Hh pathway in vitro and in vivo cancer research, and other non canonical pathways may also activate expression of GLI1. Here, we summarize GLI function in carcinogenesis and cancer-targeted therapy. PMID- 29189161 TI - Toxicology of Trastuzumab: An Insight into Mechanisms of Cardiotoxicity. AB - Trastuzumab is a humanized monoclonal antibody that is approved for the treatment of breast and gastric malignancies. Although it has shown promise as a biotherapeutic, its cardiotoxicity remains a major concern. Genotoxic anticancer anthracyclines such as doxorubicin and epirubicin are also known for their cardiotoxic effects. However, trastuzumab and anthracyclines are suggested to mediate cardiotoxicity via different pathways. The available lines of evidence suggest that trastuzumab can exacerbate the cardiotoxic effects of anthracyclines and thus, prior exposure to anthracyclines is a regarded as one of the risk factors for trastuzumab-induced cardiotoxcity. Although it is generally believed that the trastuzumab-induced cardiotoxic effects are reversible, various preclinical studies have revealed its apoptotic effects on cardiomyocytes. Thus, the issue of the reversibility of its cardiotoxic effects remains to be fully resolved. This article discusses various mechanisms that have been proposed for the cardiotoxic effects of trastuzumab and the potential risk factors that can lead to cardiotoxicity. The recently approved anti-HER2 monoclonal antibodies including pertuzumab and ado-trastuzumab (T-DM1) are also discussed. PMID- 29189162 TI - Tunneling Nanotubes: A Versatile Target for Cancer Therapy. AB - Currently Cancer is the leading cause of death worldwide. Malignancy or cancer is a class of diseases characterized by uncontrolled cell growth that eventually invade other tissues and develop secondary malignant growth at other sites by metastasis. Intercellular communication plays a major role in cancer, particularly in the process of cell proliferation and coordination which in turn leads to tumor invasion, metastasis and development of resistance to therapy. Cells communicate among themselves in a variety of ways, namely: i) via gap junctions with adjacent cells; ii) via exosomes with nearby cells; and iii) via chemical messengers with distant cells. Besides, cell - cell connection by tunneling nanotubes (TnTs) is recently gaining importance where intercellular components are transferred between cells. In general cell organelles like Golgi vesicle and mitochondria; and biomolecules like nucleic acids and proteins are transferred through these TnTs. These TnTs are long cytoplasmic extensions made up of actin that function as intercellular bridge and connect a wide variety of cell types. Malignant cells form TnTs with either other malignant cells or cells of the surrounding tumor matrix. These TnTs help in the process of initiation of tumor formation, its organization and propagation. The current review focuses on the role of TnTs mediated cell - cell signaling in cancer micro-environment. Drugs that inhibit TnT-formation such as metformin and everolimus can be targeted towards TnTs in the management of cancer growth, proliferation, tumor invasion and metastasis. PMID- 29189164 TI - Alzheimer: A Decade of Drug Design. Why Molecular Topology can be an Extra Edge? AB - BACKGROUND: The last decade was characterized by a growing awareness about the severity of dementia in the field of age-related and no age-related diseases and about the importance to invest resources in the research of new, effective treatments. Among the dementias, Alzheimer's plays a substantial role because of its extremely high incidence and fatality. Several pharmacological strategies have been tried but still now, Alzheimer keeps being an untreatable disease. In literature, the number of QSAR related drug design attempts about new treatments for Alzheimer is huge, but only few results can be considered noteworthy. Providing a detailed analysis of the actual situation and reporting the most notable results in the field of drug design and discovery, the current review focuses on the potential of molecular topology as a reliable tool in finding new anti-Alzheimer lead compounds. METHODS: Published works on QSAR applied to the search of anti-Alzheimer's drugs during the last 10 years has been tracked. 2D and 3D-QSAR, HQSAR, topological indexes, etc. have been analyzed, as well as different mechanisms of action, such as MAO, AchE, etc. An example of topological indexes' application to the search of potential anti-Alzheimer drugs is reported. RESULTS: Results show that QSAR methods during the last decade represented an excellent approach to the search of new effective drugs against Alzheimer's. In particular, QSAR based on molecular topology allows the establishment of a direct structure-property link that results in the identification of new hits and leads. CONCLUSION: Molecular topology is a powerful tool for the discovery of new anti Alzheimer drugs covering simultaneously different mechanisms of action, what may help to find a definitive cure for the disease. PMID- 29189163 TI - Alpha-synuclein, Proteotoxicity and Parkinson's Disease: Search for Neuroprotective Therapy. AB - BACKGROUND: There is a growing body of evidence in animal and cell based models of Parkinson's disease (PD) to suggest that overexpression and / or abnormal accumulation and aggregation of alpha-synuclein can trigger neuronal death. This important role of alpha-synuclein in PD pathogenesis is supported by the fact that duplication, triplication and mutations of alpha-synuclein gene cause familial forms of PD. METHODS: A review of literature was performed by searching PubMed and Google Scholar for relevant articles highlighting the pathogenic role of alpha-synuclein and the potential therapeutic implications of targeting various pathways related to this protein. RESULTS: The overexpression and accumulation of alpha-synuclein within neurons may involve both transcriptional and post-transcriptional mechanisms including a decreased degradation of the protein through proteasomal or autophagic processes. The mechanisms of monomeric alpha-synuclein aggregating to oligomers and fibrils have been investigated intensively, but it is still not certain which form of this natively unfolded protein is responsible for toxicity. Likewise the proteotoxic pathways induced by alpha- synuclein leading to neuronal death are not elucidated completely but mitochondrial dysfunction, endoplasmic reticulum (ER) stress and altered ER-golgi transport may play crucial roles in this process. At the molecular level, the ability of alpha-synuclein to form pores in biomembranes or to interact with specific proteins of the cell organelles and the cytosol could be determining factors in the toxicity of this protein. CONCLUSION: Despite many limitations in our present knowledge of physiological and pathological functions of alpha synuclein, it appears that this protein may be a target for the development of neuroprotective drugs against PD. This review has discussed many such potential drugs which prevent the expression, accumulation and aggregation of alpha synuclein or its interactions with mitochondria or ER and thereby effectively abolish alpha-synuclein mediated toxicity in different experimental models. PMID- 29189165 TI - Childhood Medulloblastoma: Current Therapies, Emerging Molecular Landscape and Newer Therapeutic Insights. AB - BACKGROUND: Medulloblastoma is the most common malignant brain tumor in children, currently treated uniformly based on histopathology and clinico-radiological risk stratification leading to unpredictable relapses and therapeutic failures. Identification of molecular subgroups have thrown light on the reasons for these and now reveals clues to profile molecularly based personalized therapy against these tumors. METHODS: Research and online contents were evaluated for pediatric medulloblastoma which included latest information on the molecular subgroups and their clinical relevance and update on efforts to translate them into clinics. RESULTS: Scientific endeavors over the last decade have clearly identified four molecular variants (WNT, SHH, Group 3, and Group 4) and their demographic, genomic, and epigenetic profile. Latest revelations include significant heterogeneity within these subgroups and 12 different subtypes of MB are now identified with disparate outcomes and biology. These findings have important implications for stratification and profiling future clinical trials against these formidable tumors. CONCLUSION: With the continued outpouring of genomic/epigenomic data of these molecular subgroups and evolution of further subtypes in each subgroup, the challenge lies in comprehensive evaluation of these informations. Current and future endeavors are now needed to profile personalized therapy for each child based on the molecular risk stratification of medulloblastoma, with a hope to improve survival outcome and reduce relapses. PMID- 29189168 TI - Targeting cytokines for morphine tolerance: a narrative review. AB - BACKGROUND: Despite its various side effects, morphine has been widely used in clinics for decades due to its powerful analgesic effect. Morphine tolerance is one of the major side effects which hinders its long-term usage for pain therapy. Currently, the thorough cellular and molecular mechanisms underlying morphine tolerance remain largely uncertain. METHODS: We searched the PubMed database with Medical subject headings (MeSH) including 'morphine tolerance', 'cytokines', 'interleukin 1', 'interleukin 1 beta', 'interleukin 6', 'tumor necrosis factor alpha', 'interleukin 10', 'chemokines'. Manual searching was carried out by reviewing the reference lists of relevant studies obtained from the primary search. The searches covered the period from inception to November 1, 2017. RESULTS: The expression levels of certain chemokines and pro-inflammatory cytokines were significantly increased in animal models of morphine tolerance. Cytokines and cytokine receptor antagonist showed potent effect of alliviating the development of morphine tolerance. CONCLUSION: Cytokines play a fundamental role in the development of morphine tolerance. Therapeutics targeting cytokines may become alternative strategies for the management of morphine tolerance. PMID- 29189166 TI - Oxytocin and Eating Disorders: A Narrative Review on Emerging Findings and Perspectives. AB - BACKGROUND: The hypothalamic neuropeptide oxytocin regulates reproductive behavior and mother-infant interaction, and conclusive studies in humans indicate that oxytocin is also a potent modulator of psychosocial function. Pilot experiments have yielded first evidence that this neuropeptide moreover influences eating behavior. METHODS: We briefly summarize currently available studies on the involvement of the oxytocin system in the pathophysiology of eating disorders, as well as on the effects of oxytocin administration in patients with these disorders. RESULTS: Brain administration of oxytocin in animals with normal weight, but also with diet-induced or genetically induced obesity, attenuates food intake and reduces body weight. In normal-weight and obese individuals, acute intranasal oxytocin delivery curbs calorie intake from main dishes and snacks. Such effects might converge with the poignant social and cognitive impact of oxytocin to also improve dysfunctional eating behavior in the therapeutic context. This assumption has received support in first studies showing that oxytocin might play a role in the disease process of anorexia nervosa. In contrast, respective experiments in patients with bulimia nervosa and binge eating disorder are still scarce. CONCLUSIONS: We propose a framework of oxytocin's role and its therapeutic potential in eating disorders that aims at integrating social and metabolic aspects of its pharmacological profile, and ponder perspectives and limitations of oxytocin use in the clinical setting. PMID- 29189167 TI - 3D-QSAR and in-silico Studies of Natural Products and Related Derivatives as Monoamine Oxidase Inhibitors. AB - BACKGROUND: The computational development of human monoamine oxidase (MAO) inhibitors led to advancement in drug design and the treatment of many neurodegenerative diseases and neuropsychiatric disorders.

CONCLUSION: It is clear that, by this computational drug design approach, more particular, reversible and potent compounds can be proposed as MAO inhibitors by exact changes on the fundamental framework. PMID- 29189170 TI - Paraoxonase-1: Characteristics and role in atherosclerosis and carotid artery disease. AB - Paraoxonase-1 (PON-1) is a calcium-dependent enzyme that is synthesized in the liver and then secreted in blood where it is bound to high density lipoprotein(HDL). PON-1 is a hydrolase with a wide range of substrates, including lipid peroxides. It is considered responsible for many of the antiatherogenic properties of HDL. PON-1 prevents low density lipoprotein (LDL) oxidation, a process that is considered to contribute to the initiation and development of atherosclerosis. PON-1 activity and levels areinfluenced by gene polymorphisms; of the 2 common variants, one is in position 192 (Q192R) and one in position 55 (M55L). Also, many drugs affect PON-1 activity. The role of PON-1 in carotid atherosclerosis is inconsistent. Some studies show an association of PON-1 polymorphisms with carotid plaque formation, whereas others do not. The aim of this review is to summarize the characteristics of PON-1,its interactions with drugs and its role in atherosclerosis and especially its relationship with carotid artery disease. PMID- 29189169 TI - Computer-aided Drug Design Applied to Parkinson Targets. AB - BACKGROUND: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by debilitating motor deficits, as well as autonomic problems, cognitive declines, changes in affect and sleep disturbances. Although the scientific community has performed great efforts in the study of PD, and from the most diverse points of view, the disease remains incurable. The exact mechanism underlying its progression is unclear, but oxidative stress, mitochondrial dysfunction and inflammation are thought to play major roles in the etiology. OBJECTIVE: Current pharmacological therapies for the treatment of Parkinson's disease are mostly inadequate, and new therapeutic agents are much needed. METHODS: In this review, recent advances in computer-aided drug design for the rational design of new compounds against Parkinson disease; using methods such as Quantitative Structure-Activity Relationships (QSAR), molecular docking, molecular dynamics and pharmacophore modeling are discussed. RESULTS: In this review, four targets were selected: the enzyme monoamine oxidase, dopamine agonists, acetylcholine receptors, and adenosine receptors. CONCLUSION: Computer aided-drug design enables the creation of theoretical models that can be used in a large database to virtually screen for and identify novel candidate molecules. PMID- 29189171 TI - Challenges in Treatment of Inappropriate Sinus Tachycardia. AB - BACKGROUND: Inappropriate Sinus Tachycardia (IST) is a clinical syndrome characterized by a sinus heart rate inexplicably higher than one hundred beats per minute at rest that is associated with symptoms like palpitations, dyspnea or dizziness in the absence of primary causes of tachycardia. The diagnosis requires exclusion of other causes of tachycardia including medications/substances (such as anti-cholinergic, beta-blocker withdrawal, caffeine, and alcohol) or medical conditions (such as panic attacks, pulmonary embolism, fever, hyperthyroidism, hypovolemia, anemia, and pain). METHODS: Work up should include an EKG to differentiate other causes of tachycardia, 24 hour- Holter monitor if indicated, serum thyroid levels, hemoglobin levels and toxicology screen. Electrophysiological studies are not routinely recommended, but should be considered in certain patients in whom concurrent supraventricular tachycardia is suspected. CONCLUSION: The underlying pathology in IST is yet to be completely understood. However, it is thought that the causes of IST can be broadly classified into two groups; either as an intrinsic increase in sinus node automaticity or an extrinsic cause. Among extrinsic causes, there is evolving evidence that IgG anti-beta receptor antibodies are found in IST causing tachycardia. Managing patients with IST includes lifestyle modification, non pharmacological and pharmacological interventions. Ivabradine has recently emerged as an effective treatment of IST and was shown to be superior to beta blockers. PMID- 29189174 TI - Xanthine Oxidase Inhibitory and Molecular Docking Studies on Pyrimidones. AB - BACKGROUND: Xanthine oxidase is an important enzyme which catalyzes the production of uric acid and superoxide anion from xanthine. The over-production of these products leads to different disease conditions. For instance, uric acid is responsible for hyperuricemia, gout, and arthritis, while superoxide anion contributes to the oxidative stress, and related diseases. Hence XO is an important pharmacological target for the treatment of a range of diseases. METHODS: Based on the structural resemblance of pyrimidines with xanthine, a series of previously synthesized ethyl 6- methyl-2-oxo-1, 2, 3, 4-tetrahydro-5 pyrimidinecarboxylate derivatives were evaluated for XO inhibitory activity. RESULTS: Among 25 pyrimidone derivatives, 22 were found to be good to weak inhibitors with IC50 values in the range of 14.4 - 418 uM. Compounds 3, 14, 15, 18, and 21-23 were significant inhibitors, and thus analyzed for their kinetic parameters. Among them compounds 14, 15, 18, and 23 were competitive, 21 and 22 showed non-competitive, while 23 was a mixed-type of inhibitor. Molecular docking studies highlighted the interactions of these inhibitors with critical amino acids of XO, such as Val1011, Phe649, Lys771, and others. Moreover, the cytotoxicity studies on these selected inhibitors showed all these compounds to be non-cytotoxic. CONCLUSION: These non-cytotoxic, significant XO inhibitors can thus be further investigated for the treatment of hyperuricemia, and gout. PMID- 29189172 TI - Cardiovascular Disease in the Setting of Human Immunodeficiency Virus Infection. AB - BACKGROUND: Since the introduction of Antiretroviral Therapy (ART), the life expectancy and health quality for patients infected with Human Immunodeficiency Virus (HIV) have significantly improved. Nevertheless, as a result of not only the deleterious effects of the virus itself and prolonged ART, but also the effects of aging, cardiovascular diseases have emerged as one of the most common causes of death among these patients. OBJECTIVE: The purpose of this review is to explore the new insights on the spectrum of Cardiovascular Disease (CVD) in HIV infection, with emphasis on the factors that contribute to the atherosclerotic process and its role in the development of acute coronary syndrome in the setting of infection. METHODS: A literature search using PubMed, ScienceDirect and Web of Science was performed. Articles up to Mar, 2017, were selected for inclusion. The search was conducted using MeSH terms, with the following key terms: [human immunodeficiency virus AND (cardiovascular disease OR coronary heart disease) AND (antiretroviral therapy AND (cardiovascular disease OR coronary heart disease))]. RESULTS: Clinical cardiovascular disease tends to appear approximately 10 years before in infected individuals, when compared to the general population. The pathogenesis behind the cardiovascular, HIV-associated complications is complex and multifactorial, involving traditional CVD risk factors, as well as factors associated with the virus itself - immune activation and chronic inflammation - and the metabolic disorders related to ART regimens. CONCLUSION: Determining the cardiovascular risk among HIV-infected patients, as well as targeting and treating conditions that predispose to CVD, are now emerging concerns among physicians. PMID- 29189173 TI - Prodrugs for Nitroreductase Based Cancer Therapy- 1: Metabolite Profile, Cell Cytotoxicity and Molecular Modeling Interactions of Nitro Benzamides with Ssap NtrB. AB - BACKGROUND: Directed Enzyme Prodrugs Therapy (DEPT) as an alternative method against conventional cancer treatments, in which the non-toxic prodrugs is converted to highly cytotoxic derivative, has attracted an ample attention in recent years for cancer therapy studies. OBJECTIVE: The metabolite profile, cell cytotoxicity and molecular modeling interactions of a series of nitro benzamides with Ssap-NtrB were investigated in this study. METHOD: A series of nitro substituted benzamide prodrugs (1-4) were synthesized and firstly investigated their enzymatic reduction by Ssap-NtrB (S. saprophyticus Nitroreductase B) using HPLC analysis. Resulting metabolites were analyzed by LC-MS/MS. Molecular docking studies were performed with the aim of investigating the relationship between nitro benzamide structures (prodrugs 1-4) and Ssap-NtrB at the molecular level. Cell viability assay was conducted on two cancer cell lines, hepatoma (Hep3B) and colon (HT-29) cancer models and healthy cell model HUVEC. Upon reduction of benzamide prodrugs by Ssap-NtrB, the corresponding amine effectors were tested in a cell line panel comprising PC-3, Hep3B and HUVEC cells and were compared with the established NTR substrates, CB1954 (an aziridinyl dinitrobenzamide). RESULTS: Cell viability assay resulted in while prodrugs 1, 2 and 3 had no remarkable cytotoxic effects, prodrug 4 showed the differential effect, showing moderate cytotoxicity with Hep3B and HUVEC. The metabolites that obtained from the reduction of nitro benzamide prodrugs (1-4) by Ssap-NtrB, showed differential cytotoxic effects, with none toxic for HUVEC cells, moderate toxic for Hep3B cells, but highly toxic for PC3 cells. CONCLUSION: Amongst all metabolites of prodrugs after Ssap-NtrB reduction, N-(2,4- dinitrophenyl)-4-nitrobenzamide (3) was efficient and toxic in PC3 cells as comparable as CB1954. Kinetic parameters, molecular docking and HPLC results also confirm that prodrug 3 is better for Ssap NtrB than 1, 2 and 4 or known cancer prodrugs of CB1954 and SN23862, demonstrating that prodrug 3 is an efficient candidate for NTR based cancer therapy. PMID- 29189175 TI - Fracture Risk Associated with Use of Antibiotics. AB - BACKGROUND: Data have pointed at an impaired fracture healing with fluoroquinolones and thus potentially a decreased bone biomechanical competence. OBJECTIVES: To study fracture risk associated with antibiotics. METHODS: It is a case control study. There were 124,655 fracture cases and 373,962 age and gender matched controls. The main exposure was use of various groups of antibiotics. Confounder control was performed for social variables, contacts to hospitals and general practitioners, alcoholism and a number of other variables. RESULTS: An increased risk of any fracture (OR =1.45, 95% CI: 1.42 -1.49), hip (1.46, 95% CI: 1.35- 1.58), forearm (1.67, 95% CI: 1.55 -1.80), and spine fractures (1.38, 95% CI: 1.18-1.60) was seen with the use of dicloxacillin and flucloxacillin. There was a dose response relationship for overall risk of fractures, hip, and forearm fractures but not for spine fractures with dicloxacillin and flucloxacillin. None of the other groups of antibiotics against bacteria, tuberculosis, virus, and fungi were systematically associated with any major change in the risk of fractures. CONCLUSION: Dicloxacillin and flucloxacillin seem associated with an increased risk of fractures. The cause for this increase has to be determined but may be related to their use against infections of the bone, the increase thus rather being due to the underlying disease than the drug. Other types of antibiotics especially the fluoroquinolones were not systematically associated with an increased risk of fractures. PMID- 29189176 TI - The Emerging Role of Complement C3 as A Biomarker of Insulin Resistance and Cardiometabolic Diseases: Preclinical and Clinical Evidence. AB - BACKGROUND: An intricate network of reciprocal interactions between adipose tissue and immune system have been largely demonstrated, leading to the well accepted concept of insulin resistance as a low grade inflammatory state and, conversely, chronic high-grade inflammation as a dysmetabolic condition. Immune homeostasis is regulated by several players including the complement system, a complex protein network at the crossroad between the innate and adaptive arms of the human defences against pathogens. OBJECTIVE: Complement C3 represents the nodal point of the complement cascade independently of the pathway recruited. Aim of this review is to collect the evidence supporting the role of complement C3 as a candidate biomarker of insulin resistance and other metabolic disorders. METHODS: We reviewed the available evidence pointing to a role of complement system, and in particular complement C3, in insulin resistance and other cardiometabolic diseases including diabetes (T2D), hypertension, non-alcoholic fatty liver disease (NAFLD) and atherosclerosis. RESULTS: Compelling preclinical evidence demonstrated a role of adipose-tissue C3 and its cleavage products C3a and acylation stimulating protein (ASP) in adipose tissue inflammation and insulin resistance. To further support this hypothesis, several clinical studies, both cross-sectional and longitudinal, confirmed this association in independent cohorts. Moreover, preliminary evidence support a role of complement C3 in other cardiometabolic diseases such as hypertension, NAFLD and atherosclerosis. CONCLUSION: Future studies are needed to fully confirm the usefulness of C3 as a clinical biomarker and to establish accurate cut-off values. Moreover, the therapeutic potential of C3 modulation in either cardiometabolic and inflammatory diseases need to be investigated. PMID- 29189177 TI - Brain Cancer: Implication to Disease, Therapeutic Strategies and Tumor Targeted Drug Delivery Approaches. AB - BACKGROUND: Cancer is one of the leading causes of morbidity and mortality worldwide. Brain cancer is identified as one of the most formidable forms of cancer due to several hurdles posed by the anatomy and physiology of the brain on the therapeutic strategies employed for treating brain cancer. Poor prognosis and high relapse rate further aggravate the situation leading to the high mortality rate in brain cancer. OBJECTIVE: The present review gives a brief insight on different aspects of brain cancer by elucidating its types, causative factors, associated symptoms, diagnostic techniques, treatment strategies and limitations of current treatment strategies. The review summarizes novel drug delivery based treatment strategies for tumor targeting. METHODS: Conventional surgical or chemotherapy based strategies are less efficient for treating brain cancer. Surgery is risky because extracting the tumors can permanently damage the brain and alter the patient's ability to function. Sometimes, surgery cannot be performed because of the anatomical location of the tumor which is beyond the reach or near to any vital region. Drug based therapy requires heavy doses to cross the blood brain barrier leading to systemic toxicity. The review summarizes fifteen different patented technologies for targeting the drug substance specifically to the tumor site in the brain. RESULT: Targeted drug delivery strategies serve as an efficient tool for treating brain cancer. CONCLUSION: Novel strategies focused towards targeting drug substances specifically to brain tumor site would increase the therapeutic efficiency and reduce the toxicity of chemotherapeutics. PMID- 29189178 TI - Targeting Mevalonate Pathway in Cancer Treatment: Repurposing of Statins. AB - BACKGROUND: Modifications of lipid metabolism have been progressively accepted as a hallmark of tumor cells and in particular, an elevated lipogenesis has been described in various types of cancers. OBJECTIVE: Important or deregulated activity of the mevalonate pathway has been demonstrated in different tumors and a wide range of studies have suggested that tumor cells are more dependent on the unceasing availability of mevalonate pathway metabolites than their non-malignant complements. METHODS: This study provides an overview of the state of the art of statins treatment on human cancer. RESULTS: In recent times, various actions have been proposed for statins in different physiological and pathological conditions beyond anti-inflammation and neuroprotection activity. Statins have been shown to act through mevalonate-dependent and -independent mechanisms able to affect several tissue functions and modulating specific signal transduction pathways that could account for statin pleiotropic effect. Based on their characteristics, statins represent ideal candidates for repositioning in cancer therapy. CONCLUSION: In this review article, we provide an overview of the current preclinical and clinical status of statins as antitumor agents. In addition, we evaluated various patents that describe the role of mevalonate pathway inhibitors and methods to determine if cancer cells are sensitive to statins treatment. PMID- 29189179 TI - Computational study of the binding modes of diverse DPN analogues on estrogen receptors (ER) and the biological evaluation of a new potential antiestrogenic ligand. AB - Estrogen (17beta-estradiol) is essential for normal growth and differentiation in the mammary gland. In the last three decades previous investigations have revealed that estrogen receptor alpha (ERalpha) plays a critical role in breast cancer. More recently, observations regarding the widespread expression of ERbeta like proteins in normal and neoplastic mammary tissues have suggested that ERbeta is also involved in the mentioned pathology. Design of new drugs both steroidal and nonsteroidal that target any of these receptors represents a promise to treat breast cancer, although it remains a challenge due to the sequence similarity between their catalytic domains. In this work we propose a new set of compounds that could effectively target the estrogen receptors ERalpha and ERbeta. These ligands were designed based on the chemical structure of the ERbeta selective agonist diarylpropionitrile (DPN). The designed ligands were submitted to in silico ADMET studies, yielding in a filtered list of ligands that showed better drug-like properties. Molecular dynamics simulations and docking analysis were carried-out employing these compounds from which two of them were chosen considering their promising characteristics obtained from theoretical results. They were chemically synthetized and during the process, two precursor ligands were also obtained. These four ligands were subjected to biological studies, where it could be detected that ligand mol60b showed inhibitory activity and its ability to activate the transcription via an estrogenic mechanism of action was also determined. Interestingly, this result coincides well to the fact that the complex of ERbeta-mol60b showed the highest DeltaGbind value from the binding free energy calculations. PMID- 29189180 TI - Design, Synthesis and Anti-breast Cancer activity of Some Novel substituted Isoxazoles as Anti-breast Cancer Agent. AB - A novel series of isoxazole (S21-S30) derivatives were designed, synthesized and screened for their anticancer activity against estrogen receptor-positive MCF-7 and negative MDA-MB-435 breast cancer cell lines. The synthesized derivative has ability to inhibit the growth of the human breast cancer cell line at low concentrations. In-vivo anticancer activity was performed on virgin female sprague dawley rats. The result shows that the compound S23 has more selectivity and marked estrogen modulator activity than the standard tamoxifen. PMID- 29189181 TI - "Good Fashion is Evolution, Not Revolution" - Methods to Enhance Existing Anticancer Medicines, Primarily with the Use of Transition Metal. AB - The constant search for successful cancer therapies lasts for decades. Apart from the huge scientific effort and enormous sum of spent money, only a small amount of newly developed medicines move into clinical use (only 94 registered anticancer drugs in the last 12 years). Anticancer regimes are still overcome by drugs invented over 50 years ago such as cisplatin and doxorubicin. Significant progress in the development of improved anticancer drugs was made due to multiple studies on the relationship between the molecular structure of chemical compounds and their cytostatic activity. A number of ligands (mainly organic) with quite effective anticancer properties are known, but they show insufficient activity, selectivity and multidrug resistance. Formation of transition metal - ligand complexes (with proven anticancer effect) changes the properties of the latter. The factors that affect the cytotoxic properties of metal complexes are: the type of ligand and metal, the nature of the connection between metal and ligand, and the distribution of electronic charge density in the formed complexes. Here, we report the recent efforts to improve existing compounds with confirmed anticancer activity. They seem to be unappreciated as their effects appear to be less spectacular than that of targeted anticancer drugs (i.e. based on antibodies or small RNAs). PMID- 29189182 TI - Design, Synthesis and Cytotoxicity Evaluation of New 3, 5-Disubstituted-2 Thioxoimidazolidinones. AB - BACKGROUND: Some 2-thioxoimidazolidinones have been reported as anti-prostate and anti-breast cancer agents through their inhibitory activity on topoisomerase I that is considered as a potential chemotherapeutic target. OBJECTIVE: A new series of 3,5-disubstituted-2-thioxoimidazolidinone derivatives 10a-f and their S methyl analogs 11a-f were designed, synthesized and evaluated for cytotoxicity against human prostate cancer cell line (PC-3), human breast cancer cell line (MCF-7) and non-cancerous human lung fibroblast cell line (WI-38). Results and Method: While compounds 10a-f showed a broad range of activities against PC-3 and MCF-7 cell lines (IC50 = 34.0 - 186.9 and 24.6 - 147.5 uM respectively), the S methyl analogs 11a-f showed (IC50 = 22.7 - 198.5 and 16.9 - 188.2 uM respectively) in comparison with 5-fluorouracil (IC50 = 60.7 and 40.7 uM respectively). 11c (IC50 = 22.7 and 29.2 uM) and 11f (IC50 = 28.7 and 16.9 uM) were the most potent among all compounds against both PC-3 and MCF-7 respectively with no cytotoxicity against WI-38. CONCLUSION: The newly synthesized compounds showed good activity against PC-3 and MCF-7 cell lines in comparison with 5 fluorouracil. Compounds 11c and 11f bound with human topoisomerase I similar to its known inhibitors and significantly inhibited its DNA relaxation activity in a dose dependent manner which may rationalize their molecular mechanism as cytotoxic agents. PMID- 29189183 TI - A Multicenter Study of IgE Sensitization to Anisakis simplex and Diet Recommendations. AB - BACKGROUND: Allergy to Anisakis simplex (s.) is spreading due to the increased consumption of raw, smoked or marinated fish. In man, Anisakis s. can directly attack the gastrointestinal mucosa, provoking a parasitosis known as anisakiasis, or giving rise to the formation of IgE and, finally, inducing IgE-mediated reactions like urticaria, angioedema and anaphylactic shock. During recent years, a dietary approach to Anisakis s. infestation has also been addressed. METHODS: A total of 620 patients with urticaria, angioedema, or both and a history of anaphylaxis following consumption of raw, smoked or marinated fish were recruited, evaluated for specific IgE levels to Anisakis s. and subjected to Skin Prick test. Following 18 month fish-free diet, patients were reevaluated at 6, 12 and 18 months, respectively. Patients undergoing diet were selected among those who had a clinical history with multiple accesses to first aid. RESULTS: After 6 month fish-free diet, we recorded an improvement of symptoms and a remarkable reduction of specific IgE levels. The extension of the diet over 6 months in some cases resulted in a further reduction of specific IgE levels. CONCLUSION: Data obtained confirm the importance of a fish-free diet in patients with severe symptoms since a new antigenic exposure coincides with a relapse of symptoms and increased IgE levels. This last point should be kept in mind and carefully evaluated in patients at risk for anaphylaxis or angioedema. PMID- 29189184 TI - Impact of Electron-Beam Irradiation on Functional Attributes of Seeds of Two Coastal Wild Legume Landraces of Canavalia. AB - BACKGROUND: Vegetable proteins have widespread application in the food industry as functional ingredients in food formulations according to the recent patents. Requirement to develop less expensive protein-rich supplementary foods has resulted in shift of emphasis towards lesser known wild than popular legumes. OBJECTIVE: The aim of this study is to expose seeds of two coastal sand dune wild legumes of the Southwest India (Canavalia cathartica and C. maritima) to different doses of electron-beam (EB) irradiation to assess changes in functional attributes. METHOD: Intact dried seeds were exposed to EB irradiation (2.5, 5, 10, 15 kGy). Protein solubility, gelation concentration, water-absorption capacity, oil-absorption capacity, emulsion properties and foam properties of control and irradiated seeds were assessed by standard methods. RESULTS: Protein solubility of both seed flours attained the highest at 2.5 kGy, followed by gradual dosedependent decrease. The gelation concentration increased in C. cathartica only at 5 kGy, while it decreased in C. maritima at 2.5 kGy without further change at higher doses. The water-absorption capacity of C. maritima was significantly higher than C. cathartica in control sample, while at 15 kGy C. cathartica showed significantly higher absorption capacity than C. maritima. The oil-absorption capacity was significantly higher in C. maritima than C. cathartica in control as well as all doses of irradiation. Emulsion activity of C. maritima was slightly higher than C. cathartica in control and irradiated samples, while both seeds showed similar emulsion stability in control with significant increase in C. cathartica at 10 kGy and 15 kGy. The foam capacity in both seeds was similar up to 2.5 kGy followed by significant increase in C. maritima at 5 kGy and 10 kGy. The foam stability was significantly higher C. cathartica than C. maritima in control as well as in irradiated samples. The foam capacity was higher in C. maritima than C. cathartica in control and irradiated samples, which showed gradual time-dependent decrease in stability with higher stability at 8 hr in C. cathartica than C. maritima. CONCLUSION: Improved functional properties (protein solubility, emulsion stability and foam capacity) and decreased gelation concentration in seeds of C. maritima irradiated at 5 kGy is advantageous in the production of functional foods. Even though both species of Canavalia grew on the coastal sand dunes and their seeds were exposed to same doses of radiation, they differed in functional attributes confirm that it is species-specific. Canavalia seeds being rich in proteins, carbohydrates, essential amino acids, essential fatty acids and bioactive components, further studies on the impact of EB irradiation helps in optimization of nutraceutical potential as well as functional attributes for future applications. PMID- 29189185 TI - Enhanced Both in vitro and in vivo Kinetics by SLNs Induced Transdermal System of Furosemide: A Novel Approach. AB - BACKGROUND: Furosemide is a potent diuretic agent used to treat pulmonary arterial hypertension. Variable dosage regimen and poor pharmacokinetic parameters have led to the development of transdermal drug delivery system. OBJECTIVE: Patent on suitability of multi-lamellar structures for excellent transdermal delivery (US0367475A1) has encouraged us to formulate the solid lipid nanoparticles (SLNs) induced transdermal systems of furosemide to enhance the kinetic properties without incorporating any penetration enhancer and rate limiting polymers. METHODS: SLNs were prepared by hot homogenization and ultra sonication method; optimization was done based on entrapment efficiency and particle size. Optimized SLNs were incorporated in to transdermal patches by solvent casting method. In vitro and in vivo studies were carried out for characterization of transdermal patches. RESULTS: SLNs of F9 (GMS: Span 60: Pluronic F 68 in 6:2.5:0.2) were optimized for incorporating in to transdermal system (entrapment efficiency 96.5+/-0.045%, particle size 69.6+/-1.48nm and in vitro release 94.38+/-1.02%). Transdermal patches were formulated using combinations of hydrophilic and hydrophobic polymers to study the diffusion kinetics. Formulation FS1 (HPMC 4 parts) was optimized for further studies (in vitro release 98.11+/-1.21% with flux of 58.726+/-0.023ug/cm2/h) and no significant difference from ex vivo permeation studies was observed. Drug release followed mixed order diffusion kinetics and super case -II transport mechanism. In vivo pharmacokinetic data of SLNs induced transdermal system suggested a 3.6 times increase in AUC and 5.4 times increase in MRT when compared with oral route. CONCLUSION: The SLNs induced transdermal patch was found to beneficial in enhancing kinetic properties both in vitro and in vivo. PMID- 29189186 TI - Furosemide - Soluplus(r) Solid Dispersion: Development and Characterization. AB - BACKGROUND: Recent patents reveal that Soluplus(r) has proved to be a promising excipient that modulates dissolution characteristics of many active pharmaceutical ingredients (WO2016161995A1, WO2016169534A1 and WO2016165676A1). OBJECTIVE: Current article investigates stable solid solution of furosemide with Soluplus(r) to enhance the dissolution properties of the drug. METHOD: Drug to carrier ratios to prepare solid dispersion were selected based on the phase solubility study. Solid dispersions of furosemide with Soluplus(r) were prepared by solvent evaporation and fusion methods. Physicochemical parameters were characterized using Fourier transform infra-red spectrophotometer, thermo- gravimetric analyzer, differential thermal analyzer, and scanning electron microscopy. Drug release from the formulations was compared using USP type II (paddle type) dissolution apparatus containing 900 mL of phosphate buffer (pH - 6.8) maintained at 37+/-0.5 degrees C at a paddle rotation speed of 50rpm. RESULTS: Fourier transform infra-red spectroscopy confirmed absence of any chemical interaction while thermo-gravimetry and differential thermal analysis showed evidences of formation of a solid solution of furosemide. No furosemide crystals were observed under scanning electron microscope in case of solid dispersion. Dissolution data indicated that furosemide dissolution was enhanced to a great extent and drug to carrier ratio of 1:10 was found to be most suitable. CONCLUSION: Solid dispersions prepared by fusion method exhibited faster drug release compared to those prepared by solvent evaporation. PMID- 29189187 TI - Thymoquinone a Potential Therapeutic Molecule from the Plant Nigella sativa: Role of Colloidal Carriers in its Effective Delivery. AB - BACKGROUND: From the past few decades, remarkable awareness has laid on the use of herbal medicines in pharmaceutical research. Thymoquinone (TQ), the main chemical constituent of Nigella Sativa (NS) plant, has been extensively explored, and revealed an array of therapeutic benefits, in different in vitro, and in vivo conditions. This review provides brief outline of the diverse therapeutics actions of TQ, and NS, viz. anti-oxidant, anti-inflammatory, anti-cancer, anti diabetic, gastroprotective, hepato-protective, anti-microbial and anti histaminic. Besides, a special emphasis has given on the use of colloidal drug delivery systems exploited hitherto, for the effective delivery of TQ and NS. OBJECTIVE: The main objective of the review was to include an intensive patent literature, available on TQ and NS, for its usefulness in different therapeutic conditions. METHODS: We embarked an organized search of bibliographic databases for peer-reviewed research literature and patent databases. The characteristics of screened papers were described, and a rational qualitative content analysis approach was applied to analyze the interventions and findings of included studies using a theoretical framework. RESULTS: In the past, various studies have carried out which undoubtedly vouch for the multifarious therapeutic roles of TQ in an array of different diseases. More than 670 research papers and around 50 review articles are available on TQ and NS in PubMed database until now, suggesting its high significance. Around 12 review articles published only on the anticancer potential, while the others on its anti- inflammatory and anti-oxidant potential. Around 120 papers included in the review revealed the therapeutic benefits of TQ. In addition to this, an intensive patent literature is also available on TQ and NS, for its usefulness in different therapeutic conditions. CONCLUSION: The findings of this review confirm the effectiveness of TQ in various pathologies viz. inflammation, cancer, diabetes, gastric, hepatic, microbial and allergies. However, the complete clinical benefit of TQ has not yet been realized, owing to its poor biopharmaceutical properties. Nevertheless, colloidal drug delivery carrier systems, could be impending in bringing forth this potential molecule to reality. PMID- 29189188 TI - Complementary, Alternative and Integrative Medicine for Childhood Atopic Dermatitis. AB - BACKGROUND: Atopic Dermatitis (AD) is a chronic relapsing dermatosis associated with itch, sleep disturbance and poor quality of life. Treatment of AD includes the use of emollients, and topical and systemic immunomodulating agents. Many patients also use complementary and alternative medicine (CAM). OBJECTIVE: This article reviews the pathophysiology of AD, clinical trials and recent patents involving various modalities of CAM in the treatment of AD. METHODS: A Medline/Pubmed search was conducted using Clinical Queries with the key terms "Chinese Medicine OR Complementary and Alternative medicine" AND "Eczema OR Atopic dermatitis". The search strategy included meta-analyses, Randomized Controlled Trials (RCTs), clinical trials, reviews and pertinent references. Patents were searched using the key term "atopic dermatitis" from www.google.com/patents, www.uspto.gov, and www.freepatentsonline.com. RESULTS: Only a few RCTs evaluated the efficacy of Chinese medicinal herbs in treating AD. There was some evidence for other modalities of CAM. Integrative Medicine (IM) usually refers to the various forms of CAM that combine conventional western medicine and Chinese medicine. Supporting evidence for the efficacy of IM in the treatment of AD is presently lacking. Integration is difficult. Western medicine practitioners are often ignorant about CAM and IM. Parents are concerned about the potential side effects of Western medicine and will tend to be non-compliant with the conventional Western component of IM. Recent patents on CAM and IM are reviewed. Most CAM patents are herbal compositions, evidence on their efficacy is generally lacking. CONCLUSION: AD is a complex disease. The psychodynamics of the child and his/her family is the reason for the often suboptimal outcomes. Both Western and CAM practitioners should collaborate to create a mutually encouraging environment for the advances of IM. CAM and IM publications and patents are reviewed. Evidence of their efficacy is generally lacking. Further research is needed. PMID- 29189189 TI - Selective Suppression of CYP3A4 mRNA and Enzyme Activity by Epidermal Growth Factor in Plated Human Hepatocytes. AB - BACKGROUND: Epidermal Growth Factor (EGF) is a well-known mitogen that has importance in cell proliferation and differentiation. This property has led to the common use of EGF as an additive to some cell culture media. EGF has been previously shown to modulate constitutive Cytochrome P450 (CYP) expression in vitro. OBJECTIVES: To assess the influence of EGF on the basal and induced expression of CYP3A4, CYP1A2 and CYP2B6 in plated human hepatocytes. METHODS: Human hepatocytes were treated with EGF with and without in the presence of positive control inducers. After treatment, CYP isoform mRNA expression and enzyme activity were measured. RESULTS: EGF at concentrations ranging from 0.001 500 ng/mL resulted in a concentration-dependent decrease in basal CYP3A4 catalytic activity by up to 92%. In contrast, rifampicin (RIF)-induced activity was decreased only slightly (up to 23%). CYP3A4 mRNA also decreased in an EGF concentrationdependent manner. In contrast to CYP3A4, CYP1A2 and CYP2B6 activity and mRNA were either not suppressed or suppressed to a lower extent. The preferential effect with CYP3A4 was confirmed in 4 additional donors using a single concentration of EGF (10 ng/mL) and time-dependence experiments revealed that suppression appeared after only 24h of treatment. CONCLUSION: Because of the larger effect on the basal CYP3A4 compared to the induced response, EGF as a media additive enables a higher dynamic range in a CYP3A4 induction assay, potentially expanding the range of donor hepatocytes suitable for use in induction studies. These findings also suggest that EGF may be an important regulator of CYP3A4 expression in vivo. PMID- 29189190 TI - Role of Repetitive Transcranial Magnetic Stimulation (rTMS) in Treatment of Addiction and Related Disorders: A Systematic Review. AB - BACKGROUND: Addiction and related disorders are devastating with their tremendous social, psychological, and physical consequences for which development of optimally effective treatments is long overdue. Repetitive Transcranial Magnetic Stimulation (rTMS) is relatively safe and is becoming an emerging therapeutic tool for these conditions. METHODS: This systematic review was conducted using PubMed, PsycINFO, PsychiatryOnline and Cochrane Library ranging from year 2001 to 2017. RESULTS: Our search selected 70 related articles of which, based on the Strength of Recommendation Taxonomy (SORT) guidelines, 11 indicated Level-1 study quality and class-B strength of recommendation for rTMS in nicotine addiction (effective in 218/289 subjects who received rTMS as found in 11 studies). Level 2/Class-B evidence was found for alcohol and cocaine addictions (Alcohol: effective in 126/193 subjects who received rTMS as found in 8 studies; Cocaine: effective in 86/128 subjects, as found in 5 studies). For food cravings, Level 3/Class-B evidence was noted (effective in 134/169, found in 7 studies). However, the evidence was limited to Level-3/Class-C for heroin (10/20 subjects received active rTMS, effective in 1 study), methamphetamine (33/48 subjects received active rTMS, effective in 2 studies), cannabis (18/18 subjects received active rTMS, effective in 1 study), and pathological gambling (31/31 subjects received active rTMS, effective in 2 studies). CONCLUSION: rTMS may serve as an emerging therapeutic option for addiction and related disorders. The major lacunae include important methodological limitations and dearth of knowledge about precise mechanism of action that need to be addressed in the future studies. PMID- 29189191 TI - Edible Mushrooms from Niger Delta, Nigeria with Heavy Metal Levels of Public Health Concern: A Human Health Risk Assessment. AB - BACKGROUND: Mushrooms (US6759049B2, CA2372185A1, DE60108325D1) can be contaminated by heavy metals as described in various patents. OBJECTIVE: This study has determined the potential human health risk associated with the consumption of mushroom in Niger Delta, Nigeria. Concentrations of Pb, Cd, Sn, Cu, Ni, Al and Zn in both wild/cultivated mushroom and background soil/substrate were determined using Atomic Absorption Spectrometer (AAS). METHODS: Heavy metal pollution was calculated using Bio-Concentration Factor (BCF) and Pollution Load Index (PLI) while human health risk assessment employed Estimated Daily Intake (EDI), Target Hazard Quotient (THQ), Hazard Index (HI), Carcinogenic Risk (CR) and Total Cancer Risk (TCR). The mean concentration of metals in mushroom and soil/substrate ranged from 0.021 mg/kg - 29.16 mg/kg and 0.01 mg/kg - 56.11 mg/kg. When compared with standards by WHO, EU, SON, DPR, USEPA and NAFDAC, 100% violation was observed in Ni, Cu, Cd, Zn and partial violation by Pb in the mushroom sample although soil heavy metal concentrations were within safe limits. RESULTS: There was bioconcentration and heavy metal enrichment as PLI ranged from 3.39 - 23.58. Estimated daily intakes were (0.00 - 0.47, 0.00 - 0.51 and 0.00 - 1.17) mg/kg/day and THQ were (0.01 - 0.46, 0.01 - 0.31 and 0.03 - 1.51) for adults, adolescents and children respectively. There was a violation of Permissible Tolerable Daily Intakes (PTDI) set by JECFA. Hazard indices were all >1, another indication of health concern. CONCLUSION: Nickel showed the highest carcinogenic risk with values of 4.83E-04 - 1.43E-01, 5.31E-04 - 1.00E-01 and 1.20E-03 - 2.29E-01 for adults, adolescents and children respectively. About 80% of TCR ranged from x10-1 - x10-3. Consumption of mushroom in Niger delta-Nigeria may pose significant health risk. PMID- 29189192 TI - Intake of dietary fat and fat subtypes and risk of premenstrual syndrome in the Nurses' Health Study II. AB - Approximately 8-20 % of reproductive-aged women experience premenstrual syndrome (PMS), substantially impacting quality of life. Women with PMS are encouraged to reduce fat intake to alleviate symptoms; however, its role in PMS development is unclear. We evaluated the association between dietary fat intake and PMS development among a subset of the prospective Nurses' Health Study II cohort. We compared 1257 women reporting clinician-diagnosed PMS, confirmed by premenstrual symptom questionnaire and 2463 matched controls with no or minimal premenstrual symptoms. Intakes of total fat, subtypes and fatty acids were assessed via FFQ. After adjustment for age, BMI, smoking, Ca and other factors, intakes of total fat, MUFA, PUFA and trans-fat measured 2-4 years before were not associated with PMS. High SFA intake was associated with lower PMS risk (relative risk (RR) quintile 5 (median=28.1 g/d) v. quintile 1 (median=15.1 g/d)=0.75; 95 % CI 0.58, 0.98; P trend=0.07). This association was largely attributable to stearic acid intake, with women in the highest quintile (median=7.4 g/d) having a RR of 0.75 v. those with the lowest intake (median=3.7 g/d) (95 % CI 0.57, 0.97; P trend=0.03). Individual PUFA and MUFA, including n-3 fatty acids, were not associated with risk. Overall, fat intake was not associated with higher PMS risk. High intake of stearic acid may be associated with a lower risk of developing PMS. Additional prospective research is needed to confirm this finding.

PMID- 29189194 TI - The dietary diversity and stunting prevalence in minority children under 3 years old: a cross-sectional study in forty-two counties of Western China. AB - As a key indicator of childhood malnutrition, few studies have focused on stunting in relation to various socio-economic factors in which disadvantaged groups face in China. We conducted a community-based cross-sectional study incorporating forty-two rural counties in seven western provinces of China in 2011. In total, 5196 children aged 6-23 months were included. We used Poisson regression to examine risk factors for inadequate minimum dietary diversity (MDD) and stunting status, respectively. Overall, the proportion of children not meeting MDD was 44.5 %. Children aged 6-11 months (adjusted risk ratio (ARR)=1.39; 95 % CI 1.31, 1.49), with two siblings (ARR=1.09; 95 % CI 1.02, 1.17), delivered at home (ARR=1.30; 95 % CI 1.20, 1.41), within Yi (ARR=1.15; 95 % CI 1.04, 1.28) or Uighur groups (ARR=1.52; 95 % CI 1.36, 1.71), with an illiterate caregiver (ARR=2.12; 95 % CI 1.52, 2.96), receiving lowest income (ARR=1.32; 95 % CI 1.17, 1.50), and with breast-feeding in the last day (ARR=1.55; 95 % CI 1.44, 1.66) were more likely to have inadequate MDD. Moreover, inadequate MDD was positively associated with stunting (ARR=1.15; 95 % CI 1.01, 1.31). Other determinants for stunting were age, sex, place of delivery, minority group and income. The stunting prevalence and proportion of inadequate MDD remained high in Western China; to reduce stunting rates of ethnic minorities, further efforts addressing appropriate dietary feeding practices are needed, especially within these groups. PMID- 29189197 TI - HR-pQCT detects alterations in bone microstructure in men with CKD stages 3 and 4, which are influenced by hormonal changes and body composition?. AB - INTRODUCTION: Factors associated with osteodystrophy in predialysis patients are poorly understood. In the present study, we attempted to evaluate the impact of body composition and hormonal regulatory factors on the bone microstructure in a group of men with chronic kidney disease (CKD) stages 3 and 4. MATERIALS AND METHODS: 46 men, aged 50 - 75 years, with previously unrecognized CKD were evaluated by high-resolution peripheral quantitative computed tomography (HR pQCT), and dual-energy X-ray absorptiometry (DXA). HR-pQCT parameters were correlated with estimated glomerular filtration rate (eGFR), age, body mass index (BMI), muscle mass index (MMI), and biochemistry. RESULTS: As compared to patients in stage 3 CKD, those with stage 4 CKD showed lower serum 25 hydroxyvitamin D (25(OH)D) and bicarbonate levels, and higher serum fibroblast growth factor 23 (FGF-23) and parathyroid hormone (PTH) levels. They also exhibited lower total, trabecular, and cortical volumetric bone mineral density, lower trabecular bone volume/tissue volume, trabecular number, trabecular and cortical thickness, and increased heterogeneity of the trabecular network. In the whole cohort, cortical bone density and thickness were negatively associated with age, PTH, and FGF-23, and positively with BMI. Trabecular bone parameters were positively associated with MMI and 25(OH)D. After simultaneously adjusting for age and eGFR, BMI, and MMI remained significantly associated with bone microstructural variables. CONCLUSION: HR-pQCT showed significant differences in bone microstructure in stage 4 vs. stage 3 CKD patients. Increased BMI, probably due to increased muscle mass, may favorably affect bone architecture in predialysis CKD patients.?. PMID- 29189196 TI - Iron, zinc, vitamin A and selenium status in a cohort of Indonesian infants after adjusting for inflammation using several different approaches. AB - Inflammation confounds the interpretation of several micronutrient biomarkers resulting in estimates that may not reflect the true burden of deficiency. We aimed to assess and compare the micronutrient status of a cohort of Indonesian infants (n 230) at aged 6, 9 and 12 months by ignoring inflammation (unadjusted) and adjusting four micronutrient biomarkers for inflammation with C-reactive protein (CRP) and alpha-1-glycoprotein (AGP) using the following methods: (1) arithmetic correction factors with the use of a four-stage inflammation model; and (2) regression modelling. Prevalence of infants with any inflammation (CRP>5 mg/l and/or AGP>1 g/l) was about 25% at each age. Compared with unadjusted values, regression adjustment at 6, 9 and 12 months generated the lowest (P50 % across all ages. In conclusion, without inflammation adjustment, Fe deficiency was grossly under-estimated and vitamin A and Zn deficiency over-estimated, highlighting the importance of correcting for the influence of such, before implementing programmes to alleviate micronutrient malnutrition. However, further work is needed to validate the proposed approaches with a particular focus on assessing the influence of varying degrees of inflammation (i.e. recurrent acute infections and low-grade chronic inflammation) on each affected nutrient biomarker. PMID- 29189198 TI - Multiple brown tumors - a rare presentation in the modern era?. AB - Chronic kidney disease (CKD) commonly evolves with disturbances in mineral and bone metabolism, currently defined as CKD-MBD. Management strategies have progressed over the years, but our knowledge regarding evaluation and treatment is still sparse. Herein, we describe a rare case of a hemodialysis patient with apparently fairly controlled hyperparathyroidism (HPTH), who developed multiple symptomatic brown tumors involving the scull, mandible, vertebrae, pelvis, and metacarpus. Parathyroidectomy allowed complete resolution of the bone lesions preventing disastrous consequences.?. PMID- 29189199 TI - Intrasellar cavernous hemangioma presenting as pituitary adenoma: A report of two cases and review of the literature. AB - Cavernous hemangioma in the sellar region is quite rare with only a handful of cases being reported in the English literature. Its clinical manifestations and imaging characteristics can mimic those of a pituitary adenoma. We report two cases of recurrent sellar lesions, both of which were clinically suspected of being pituitary adenomas but histologically confirmed as cavernous hemangiomas. The first case is of a 67-year-old female whose initial resection was diagnosed as "venous angioma". Neuroimaging performed 27 years later demonstrated significant growth of the lesion involving the right cavernous sinus and encasing the right internal carotid artery. The patient then underwent transsphenoidal endoscopic resection of the mass. At the time of the surgery, the lesion was noted to be quite vascular. The second case is a 48-year-old female who underwent emergency resection of a pituitary mass following an apoplectic event. On follow up 4 years later, the patient reported recurrence of galactorrhea, and MRI had demonstrated regrowth of the mass. She subsequently underwent subtotal resection of the mass. At the time of surgery, brisk bleeding was noted in the operative area. The above two cases demonstrate that cavernous hemangiomas in the sellar region can clinically and radiologically mimic pituitary adenoma and should be considered in the differential diagnosis of hemorrhagic sellar mass.?.

AB - Herein, we report the control of the optical properties of metal nanodimer structures using electrochemical metal dissolution reactions. The reaction rate could be precisely tuned by changing the electrochemical potential and, as a consequence, fine tuning of the size and gap distance of metal nanodimers was achieved as the functions of applied potential and polarization time. The observed linear correlation between the scattering intensity and charge resulting from nanostructure dissolutions suggested that the surface dissolution rate was 0.30 nm min-1, corresponding to the surface dissolution of a single atomic layer per min. The present method can control the change in the volume of the structures, leading to the change in the gap distance of nanodimers at an atomic scale level. PMID- 29189203 TI - Proteomic characterization of human exhaled breath condensate. AB - To improve biomedical knowledge and to support biomarker discovery studies, it is essential to establish comprehensive proteome maps for human tissues and biofluids, and to make them publicly accessible. In this study, we performed an in-depth proteomics characterization of exhaled breath condensate (EBC), a sample obtained non-invasively by condensation of exhaled air that contains submicron droplets of airway lining fluid. Two pooled samples of EBC, each obtained from 10 healthy donors, were processed using a straightforward protocol based on sample lyophilization, in-gel digestion and liquid chromatography tandem-mass spectrometry analysis. Two 'technical' control samples were processed in parallel to the pooled samples to correct for exogenous protein contamination. A total of 229 unique proteins were identified in EBC among which 153 proteins were detected in both EBC pooled samples. A detailed bioinformatics analysis of these 153 proteins showed that most of the proteins identified corresponded to proteins secreted in the respiratory tract (lung, bronchi). Eight proteins were salivary proteins. Our dataset is described and has been made accessible through the ProteomeXchange database (dataset identifier: PXD007591) and is expected to be useful for future MS-based biomarker studies using EBC as the diagnostic specimen. PMID- 29189201 TI - Time-gated detection of protein-protein interactions with transcriptional readout. AB - Transcriptional assays, such as yeast two-hybrid and TANGO, that convert transient protein-protein interactions (PPIs) into stable expression of transgenes are powerful tools for PPI discovery, screens, and analysis of cell populations. However, such assays often have high background and lose information about PPI dynamics. We have developed SPARK (Specific Protein Association tool giving transcriptional Readout with rapid Kinetics), in which proteolytic release of a membrane-tethered transcription factor (TF) requires both a PPI to deliver a protease proximal to its cleavage peptide and blue light to uncage the cleavage site. SPARK was used to detect 12 different PPIs in mammalian cells, with 5 min temporal resolution and signal ratios up to 37. By shifting the light window, we could reconstruct PPI time-courses. Combined with FACS, SPARK enabled 51 fold enrichment of PPI-positive over PPI-negative cells. Due to its high specificity and sensitivity, SPARK has the potential to advance PPI analysis and discovery. PMID- 29189204 TI - Optimized efficiency in InP nanowire solar cells with accurate 1D analysis. AB - Semiconductor nanowire arrays are a promising candidate for next generation solar cells due to enhanced absorption and reduced material consumption. However, to optimize their performance, time consuming three-dimensional (3D) opto electronics modeling is usually performed. Here, we develop an accurate one dimensional (1D) modeling method for the analysis. The 1D modeling is about 400 times faster than 3D modeling and allows direct application of concepts from planar pn-junctions on the analysis of nanowire solar cells. We show that the superposition principle can break down in InP nanowires due to strong surface recombination in the depletion region, giving rise to an IV-behavior similar to that with low shunt resistance. Importantly, we find that the open-circuit voltage of nanowire solar cells is typically limited by contact leakage. Therefore, to increase the efficiency, we have investigated the effect of high bandgap GaP carrier-selective contact segments at the top and bottom of the InP nanowire and we find that GaP contact segments improve the solar cell efficiency. Next, we discuss the merit of p-i-n and p-n junction concepts in nanowire solar cells. With GaP carrier selective top and bottom contact segments in the InP nanowire array, we find that a p-n junction design is superior to a p-i-n junction design. We predict a best efficiency of 25% for a surface recombination velocity of 4500 cm s-1, corresponding to a non-radiative lifetime of 1 ns in p-n junction cells. The developed 1D model can be used for general modeling of axial p-n and p-i-n junctions in semiconductor nanowires. This includes also LED applications and we expect faster progress in device modeling using our method. PMID- 29189205 TI - High-density amorphous ice: nucleation of nanosized low-density amorphous ice. AB - The pressure dependence of the crystallization temperature of different forms of expanded high-density amorphous ice (eHDA) was scrutinized. Crystallization at pressures 0.05-0.30 GPa was followed using volumetry and powder x-ray diffraction. eHDA samples were prepared via isothermal decompression of very high density amorphous ice at 140 K to different end pressures between 0.07-0.30 GPa (eHDA0.07-0.3). At 0.05-0.17 GPa the crystallization line T x (p) of all eHDA variants is the same. At pressures >0.17 GPa, all eHDA samples decompressed to pressures <0.20 GPa exhibit significantly lower T x values than eHDA0.2 and eHDA0.3. We rationalize our findings with the presence of nanoscaled low-density amorphous ice (LDA) seeds that nucleate in eHDA when it is decompressed to pressures <0.20 GPa at 140 K. Below ~0.17 GPa, these nanosized LDA domains are latent within the HDA matrix, exhibiting no effect on T x of eHDA<0.2. Upon heating at pressures ?0.17 GPa, these nanosized LDA nuclei transform to ice IX nuclei. They are favored sites for crystallization and, hence, lower T x . By comparing crystallization experiments of bulk LDA with the ones involving nanosized LDA we are able to estimate the Laplace pressure and radius of ~0.3-0.8 nm for the nanodomains of LDA. The nucleation of LDA in eHDA revealed here is evidence for the first-order-like nature of the HDA -> LDA transition, supporting water's liquid-liquid transition scenarios. PMID- 29189206 TI - Weakly spin-dependent band structures of antiferromagnetic perovskite LaMO3 (M = Cr, Mn, Fe). AB - We investigate the spin-dependent electronic states of antiferromagnetic (AFM) lanthanum chromite (LaCrO3), lanthanum manganite (LaMnO3), and lanthanum ferrite (LaFeO3) using spin-polarized first-principles density functional theory with Hubbard U correction. The band structures are calculated for 15 types of their different AFM structures. It is verified for these structures that there is a very simple rule to identify which wave number [Formula: see text] exhibits spin splitting or degeneracy in the band structure. This rule uses the symmetry operations that map the up-spin atoms onto the down-spin atoms. The resulting spin splitting is very small for the most stable spin configuration of the most stable experimental structure. We discuss a plausible benefit of this characteristic, i.e. the direction-independence of the spin current, in electrode applications. PMID- 29189207 TI - PSF reconstruction for Compton-based prompt gamma imaging. AB - Compton-based prompt gamma (PG) imaging has been proposed for in vivo range verification in proton therapy. However, several factors degrade the image quality of PG images, some of which are due to inherent properties of a Compton camera such as spatial resolution and energy resolution. Moreover, Compton-based PG imaging has a spatially variant resolution loss. In this study, we investigate the performance of the list-mode ordered subset expectation maximization algorithm with a shift-variant point spread function (LM-OSEM-SV-PSF) model. We also evaluate how well the PG images reconstructed using an SV-PSF model reproduce the distal falloff of the proton beam. The SV-PSF parameters were estimated from simulation data of point sources at various positions. Simulated PGs were produced in a water phantom irradiated with a proton beam. Compared to the LM-OSEM algorithm, the LM-OSEM-SV-PSF algorithm improved the quality of the reconstructed PG images and the estimation of PG falloff positions. In addition, the 4.44 and 5.25 MeV PG emissions can be accurately reconstructed using the LM OSEM-SV-PSF algorithm. However, for the 2.31 and 6.13 MeV PG emissions, the LM OSEM-SV-PSF reconstruction provides limited improvement. We also found that the LM-OSEM algorithm followed by a shift-variant Richardson-Lucy deconvolution could reconstruct images with quality visually similar to the LM-OSEM-SV-PSF reconstructed images, while requiring shorter computation time. PMID- 29189208 TI - Extraneuraxial Hemangioblastoma: Clinicopathologic Features and Review of the Literature. AB - Extraneuraxial hemangioblastoma occurs in nervous paraneuraxial structures, somatic tissues, and visceral organs, as part of von Hippel-Lindau disease (VHLD) or in sporadic cases. The VHL gene plausibly plays a key role in the initiation and tumorigenesis of both central nervous system and extraneuraxial hemangioblastoma, therefore, the underlying molecular and genetic mechanisms of the tumor growth are initially reviewed. The clinical criteria for the diagnosis of VHLD are summarized, with emphasis on the distinction of sporadic hemangioblastoma from the form fruste of VHLD (eg, hemangioblastoma-only VHLD). The world literature on the topic of extraneuraxial hemangioblastomas has been comprehensively reviewed with ~200 cases reported to date: up to 140 paraneuraxial, mostly of proximal spinal nerve roots, and 65 peripheral, 15 of soft tissue, 6 peripheral nerve, 5 bone, and 39 of internal viscera, including 26 renal and 13 nonrenal. A handful of possible yet uncertain cases from older literature are not included in this review. The clinicopathologic features of extraneuraxial hemangioblastoma are selectively presented by anatomic site of origin, and the differential diagnosis is emphasized in these subsets. Reference is made also to 10 of the authors' personal cases of extraneuraxial hemangioblastomas, which include 4 paraneuraxial and 6 peripheral (2 soft tissue hemangioblastoma and 4 renal). PMID- 29189209 TI - Temporal Trends in Difficult and Failed Tracheal Intubation in a Regional Community Anesthetic Practice. AB - BACKGROUND: When tracheal intubation is difficult or unachievable before surgery or during an emergent resuscitation, this is a critical safety event. Consensus algorithms and airway devices have been introduced in hopes of reducing such occurrences. However, evidence of improved safety in clinical practice related to their introduction is lacking. Therefore, we selected a large perioperative database spanning 2002 to 2015 to look for changes in annual rates of difficult and failed tracheal intubation. METHODS: Difficult (more than three attempts) and failed (unsuccessful, requiring awakening or surgical tracheostomy) intubation rates in patients 18 yr and older were compared between the early and late periods (pre- vs. post-January 2009) and by annual rate join-point analysis. Primary findings from a large, urban hospital were compared with combined observations from 15 smaller facilities. RESULTS: Analysis of 421,581 procedures identified fourfold reductions in both event rates between the early and late periods (difficult: 6.6 of 1,000 vs. 1.6 of 1,000, P < 0.0001; failed: 0.2 of 1,000 vs. 0.06 of 1,000, P < 0.0001), with join-point analysis identifying two significant change points (2006, P = 0.02; 2010, P = 0.03) including a pre-2006 stable period, a steep drop between 2006 and 2010, and gradual decline after 2010. Data from 15 affiliated practices (442,428 procedures) demonstrated similar reductions. CONCLUSIONS: In this retrospective assessment spanning 14 yr (2002 to 2015), difficult and failed intubation rates by skilled providers declined significantly at both an urban hospital and a network of smaller affiliated practices. Further investigations are required to validate these findings in other data sets and more clearly identify factors associated with their occurrence as clues to future airway management advancements.

Specifically, this essay (1) identifies the driving forces that have addressed the development of rehabilitation, (2) examines how the rehabilitative strategy has been driven by the driving forces through turning points and facilitators, and (3) identifies the barriers of each force against the development of rehabilitation. Critical and scoping review of the literature was conducted from the late 1910s until the end of the century. War, economy, the power of the state, and science were identified as the driving forces that led rehabilitation to become a health strategy complementing prevention, promotion, cure, and palliation. World War I and II played as a stimulus for rehabilitation, federal funding facilitated its development, acts, amendments, and governmental programs enabled its implementation, and the acknowledgment of physical medicine and rehabilitation as medical field contributed to its international recognition as health strategy. World Health Organization's International Classification of Functioning, Disability and Health is also identified as an emerging facilitator of rehabilitation. Based on the example of United States, this article closes with recommendations toward the implementation of rehabilitation as a health strategy in countries where so far this has not occurred.

PMID- 29189214 TI - Unadjusted Bivariate Two-Group Comparisons: When Simpler is Better. AB - Hypothesis testing involves posing both a null hypothesis and an alternative hypothesis. This basic statistical tutorial discusses the appropriate use, including their so-called assumptions, of the common unadjusted bivariate tests for hypothesis testing and thus comparing study sample data for a difference or association. The appropriate choice of a statistical test is predicated on the type of data being analyzed and compared. The unpaired or independent samples t test is used to test the null hypothesis that the 2 population means are equal, thereby accepting the alternative hypothesis that the 2 population means are not equal. The unpaired t test is intended for comparing dependent continuous (interval or ratio) data from 2 study groups. A common mistake is to apply several unpaired t tests when comparing data from 3 or more study groups. In this situation, an analysis of variance with post hoc (posttest) intragroup comparisons should instead be applied. Another common mistake is to apply a series of unpaired t tests when comparing sequentially collected data from 2 study groups. In this situation, a repeated-measures analysis of variance, with tests for group-by-time interaction, and post hoc comparisons, as appropriate, should instead be applied in analyzing data from sequential collection points. The paired t test is used to assess the difference in the means of 2 study groups when the sample observations have been obtained in pairs, often before and after an intervention in each study subject. The Pearson chi-square test is widely used to test the null hypothesis that 2 unpaired categorical variables, each with 2 or more nominal levels (values), are independent of each other. When the null hypothesis is rejected, 1 concludes that there is a probable association between the 2 unpaired categorical variables. When comparing 2 groups on an ordinal or nonnormally distributed continuous outcome variable, the 2-sample t test is usually not appropriate. The Wilcoxon-Mann-Whitney test is instead preferred. When making paired comparisons on data that are ordinal, or continuous but nonnormally distributed, the Wilcoxon signed-rank test can be used. In analyzing their data, researchers should consider the continued merits of these simple yet equally valid unadjusted bivariate statistical tests. However, the appropriate use of an unadjusted bivariate test still requires a solid understanding of its utility, assumptions (requirements), and limitations. This understanding will mitigate the risk of misleading findings, interpretations, and conclusions. PMID- 29189216 TI - Factors Contributing to Memory of Acute Pain in Older Adults Undergoing Planned and Unplanned Hip Surgery. AB - OBJECTIVES: Previous research on pain memory provides inconsistent evidence about the accuracy of pain recall, and few studies have attempted to examine broad affective and contextual contributions to this phenomenon. The present research aimed to determine the accuracy of postoperative pain recall after 3 months, with respect to the context of the surgery and the congruence of affective states concurrent with the initial experience and its recall. The study also aimed to identify predictors of remembered pain by analyzing a range of sensory, cognitive, and affective factors. METHODS: Older adults, undergoing planned (N=40) and unplanned hip surgery (N=31), were enrolled in this prospective study to investigate their presurgery, postsurgery, and delayed ratings of expected, experienced, and recalled pain intensity and unpleasantness, state anxiety, and positive and negative affect. RESULTS: Memory of postoperative pain was found to be accurate, regardless of the context of the surgery. Affective states in the postoperative period were congruent with those during pain recall. The study also revealed that in planned surgery context, remembered pain was predicted by experienced postoperative pain, cognitive functions, positive and negative affect; whereas in unplanned surgery context its significant predictors included age, anxiety, and negative and positive affect. DISCUSSION: The results of this study suggest that older orthopedic patients remember postoperative pain correctly after 3 months and that mood dependence effect may contribute to memory of pain. Pain recall after planned surgery seems to depend mainly on the actual experience, while following unplanned surgery it depends on affective factors. Present findings contribute to knowledge about pain memory in older adults and have implications for patients' recovery and best practice in perioperative hospital care. PMID- 29189215 TI - Lateral Transperitoneal Adrenalectomy Versus Posterior Retroperitoneoscopic Adrenalectomy for Benign Adrenal Gland Disease: Randomized Controlled Trial at a Single Tertiary Medical Center. AB - OBJECTIVE: The aim of this study was to compare the surgical outcomes of lateral transperitoneal adrenalectomy (LTA) and posterior retroperitoneoscopic adrenalectomy (PRA) for benign adrenal tumor. BACKGROUND: Although LTA is the standard treatment for benign adrenal gland tumor, PRA has recently gained popularity. Studies comparing the surgical outcomes of the 2 approaches have reported conflicting findings and thus it remains unclear which approach is superior. METHODS: This trial was conducted between September 2012 and February 2016. Patients were randomized to either LTA or PRA groups in a 1:1 ratio using web-based randomization. The primary outcome was operative time, and the secondary outcomes were blood loss, intraoperative hemodynamic stability, postoperative pain, recovery of bowel movement, and complication rates. This trial was registered with ClincalTrials.gov, number NCT01676025. RESULTS: A total of 83 patients were randomly assigned to the LTA group (n = 42) or the PRA group (n = 41). Median follow-up was 31.3 months. The mean operative times of LTA and PRA were comparable (59.7 +/- 18.6 vs 67.6 +/- 28.7 minutes, P = 0.139). Logistic regression analysis showed that male sex [odds ratio (OR) = 4.20] and pheochromocytoma (OR = 5.06) were associated with an operative time >=60 minutes. There were no differences in the secondary outcomes between the groups. One patient in the PRA group required open conversion. CONCLUSION: Both LTA and PRA were performed safely with similar operative outcomes, and thus are comparable options for the treatment of benign adrenal gland tumor. PMID- 29189217 TI - Anterior Cutaneous Nerve Entrapment Syndrome in Children: A Prospective Observational Study. AB - OBJECTIVE: Anterior cutaneous nerve entrapment syndrome (ACNES) is often an overlooked cause of abdominal pain. Data for pediatric patients, especially with regard to the treatment modalities are scarce. The aim of this study was to present a treatment modality of ACNES with combined local subfascial anesthetic and corticosteroid injection in a prospectively collected cohort of pediatric patients. METHODS: This was a prospective observational long-term study that included pediatric patients who were diagnosed with ACNES in a tertiary care pediatric center and who were followed-up for at least 12 months (median: 1.7 y; range: 1 to 2.7 y). All children were treated by ultrasound-guided subfascial injection of 40 mg 1% lidocaine and 4 mg dexamethasone into the rectus abdominis muscle in the place of the most severe pain (trigger point infiltration). RESULTS: The study included 38 children (28, 73.7% female; median age: 15 y). The majority of patients had pain in the lower right abdominal quadrant and were diagnosed in a median of 6 (range: 0.5 to 50) months after symptoms started. Overall, 24 (63%) patients achieved sustained symptom-free remission after a median of 1 (mean: 1.6; range: 1 to 5) trigger point infiltration during the first treatment session. Five (13%) children were surgically treated because of a lack of long-term response. Children who were surgically treated required a higher number of block applications during the first session of treatment, compared with children who were successfully treated conservatively. DISCUSSION: ACNES in children can be successfully treated by a combined local subfascial anesthetic and corticosteroid trigger point infiltration. PMID- 29189218 TI - Adjacent Level Degeneration: Bryan Total Disc Arthroplasty Versus Anterior Cervical Discectomy and Fusion. AB - STUDY DESIGN: Prospective randomized, 2-center, clinical trial. OBJECTIVE: To prospectively compare adjacent level degeneration between the Bryan Cervical Disc Prosthesis and anterior cervical discectomy and fusion (ACDF), and assess the reliability of our measurements utilizing a method not previously described. SUMMARY OF BACKGROUND DATA: ACDF is a reliable and proven procedure for the treatment of radiculopathy and/or myelopathy. Despite a successful track record several limitations including adjacent segment degeneration/disease, loss of viscoelastic disc properties, perioperative immobilization, graft site morbidity, pseudarthrosis, and plating complications have been identified. An original driving force and theoretical basis for total disc arthroplasty was prevention of adjacent level degeneration. MATERIALS AND METHODS: Seventy-nine patients were enrolled and followed prospectively at 2 centers in a multicenter, Food and Drug Administration Investigational Device Exemption trial for the Bryan Cervical Disc arthroplasty. Neutral lateral radiographs were obtained preoperatively and postoperatively, and at 1-, 2-, 4-, and out to 7-year follow-up after surgery. The cephalad, adjacent level above the blinded procedure level was analyzed for all patients and time points by measuring the anteroposterior distance and the vertical disc height. A ratio was created using disc height/anteroposterior distance. RESULTS: Seventy patients (Bryan Cervical Disc N=34 and ACDF N=36) met inclusion criteria. Both fusion and arthroplasty groups showed a significant (P=0.001) decrease in disc height over time, indicative of adjacent level degeneration. Overall change in disc height between groups was not significantly different. Using our measurement technique, the overall interreviewer reliability was good [intrareviewer correlation coefficients (95% confidence interval)=0.77 (0.55-0.85)] and intrareviewer reliability was excellent [0.93 (0.91-0.94) and 0.85 (0.81-0.87)]. CONCLUSIONS: Adjacent level degeneration occurs in a similar manner in both the ACDF and total disc arthroplasty group. Our measurement technique is reliable and to the best of our knowledge not previously reported in the literature. PMID- 29189219 TI - Family Caregivers Need Our Help-And Now It's the Law.

PMID- 29189256 TI - Enteric Pathologic Manifestations of Alpha-Synucleinopathies. AB - BACKGROUND: Gastrointestinal (GI) symptoms are common in Parkinson disease (PD), often preceding neurological manifestations; however, early diagnostic utility of GI biopsies remains controversial. Studies suggest aberrant deposition of alpha synuclein (alpha-syn) follows step-wise progression in central nervous system though histologic interpretation of normal and aberrant staining patterns have shown variable results. This study examines whether GI alpha-syn mRNA expression combined with standard alpha-syn immunohistochemical staining enhance the role of GI biopsy in PD. MATERIALS AND METHODS: Four groups were examined, including pediatric (21) and adult control patients (18), PD clinic patients (17), and pathologically confirmed PD cases from hospital archives (16). Enteric nervous system alpha-syn staining was evaluated by immunohistochemistry in 33 PD and 39 controls. alpha-Syn mRNA levels were compared between patient groups using quantitative polymerase chain reaction and stomach and colon levels in PD. RESULTS: PD patients had Lewy bodies (LB) and diffuse neuronal alpha-syn staining. GI tissues from elderly controls, children, and young adults exhibited diffuse positivity. LB were limited to PD. Myenteric plexus immunoreactivity varied in different regions. Widespread staining was noted within stomach and colon. Immunoreactivity was present within esophagus, appendix, and small bowel. alpha-Syn mRNA expression was highest in PD; however, levels varied between proximal and distal GI tract. CONCLUSIONS: alpha-Syn is normally present within young and elderly enteric nervous system; furthermore, while alpha-syn mRNA is always detectable, levels are highest and most variable in PD. This suggests that enteric alpha-syn may be altered in neurodegenerative disease. The presence of LB in the GI tract, not solely alpha-syn expression, may prove useful, distinguishing neurodegenerative disease patients from normal controls.

PMID- 29189258 TI - The Use of Smoothelin and Other Antibodies in the Diagnosis of Uterine and Soft Tissue Smooth Muscle Tumors. AB - Smoothelin is a cytoplasmic protein expressed in differentiated smooth muscle cells. Immunohistochemical evaluation of smoothelin has previously been reported in gastrointestinal (GI) smooth muscle tumors, but has yet to be studied in smooth muscle tumors of uterine and other soft tissue origin. DOG1 expression is reported to be specific for GI stromal tumors; however, variable expression has been reported in leiomyosarcomas (LMS) depending on site of origin. Overexpression of p16 is common in LMS of uterine and other sites of origin, but has not been correlated with tumor grade. This study explores the differential expression of these markers, as well as caldesmon, in LMS cases to assess diagnostic utility. Using tissue microarrays and cases from Tulane Medical Center and Medical College of Wisconsin, expression of smoothelin, DOG1, caldesmon, and p16 was evaluated by immunohistochemistry in 87 cases of LMS. The cases were subdivided by location of origin into uterine (N=31) and nonuterine (N=56) with 10 of the nonuterine of GI origin, as well as by grade into low grade (N=27) and intermediate and high grade (N=60). Differential expression among different grades and locations was evaluated. The same markers were evaluated in atypical leiomyoma cases (N=4) and 1 smooth muscle tumor of uncertain malignant potential case (N=1). Smoothelin expression was also assessed in 20 benign uterine leiomyomas. Weak DOG1 expression is rare but possible in extrauterine LMS. Expression of p16 is common in both uterine and extrauterine LMS, and more frequent in higher grades. Expression of smoothelin in this study differed depending on tumor type, grade, and site of origin. All leiomyomas and most atypical leiomyomas showed cytoplasmic positivity for smoothelin, whereas only 5% of LMS had cytoplasmic expression. The study suggests smoothelin may be downregulated in the cytoplasm of malignant smooth muscle tumor cells and may serve as a supportive aid in the distinction of LMS from benign smooth muscle tumors in cases where it is difficult by morphology alone. PMID- 29189259 TI - Histologic Features Do Not Reliably Predict Mismatch Repair Protein Deficiency in Colorectal Carcinoma: The Results of a 5-Year Prospective Evaluation. AB - Most major professional medical organizations advocate universal screening for Lynch syndrome in colorectal carcinoma; however, some allow for a selective screening approach based on clinicopathologic factors including assessment of histologic features of mismatch repair protein deficiency (MMRD). We performed a prospective evaluation for histopathologic features of MMRD in colorectal carcinomas that underwent universal screening for Lynch syndrome to evaluate the ability of histology to predict MMRD. In total, 947 resected colorectal carcinomas over a 5-year period were prospectively analyzed for histologic features of MMRD and for DNA mismatch repair protein abnormalities. Histologic features of MMRD were reported as present in 281 of 947 (30%) tumors with only 109 (39%) cases demonstrating MMRD by immunohistochemistry. Histologic features of MMRD had a sensitivity of 74% [95% confidence interval (CI), 66%-80%], specificity of 78% (95% CI, 75%-81%), positive predictive value of 39% (95% CI, 32%-44%), and negative predictive value of 94% (95% CI, 92%-96%). Histologic features of MMRD in left colon/rectal tumors had a significantly lower sensitivity of 56% (95% CI, 41%-77%) compared with right colon tumors (P=0.02). Histologic rereview identified that tumor-infiltrating lymphocytes (TILs) were most likely to be incorrectly reported as absent, and 72% of cases incorrectly assessed as lacking TILs demonstrated MMRD by immunohistochemistry. We demonstrate that histologic features of MMRD do not reliably predict the presence of MMRD by immunohistochemistry. Interpretative errors in the assessment of histologic features of MMRD occur, particularly for TILs and in tumors of the left colon/rectum. PMID- 29189260 TI - Different Expression of Aldehyde Dehydrogenases 1A1 and 2 in Oral Leukoplakia With Epithelial Dysplasia and in Oral Squamous Cell Carcinoma. AB - Oral potentially malignant disorders (OPMD) may develop malignant characteristics and transform into oral squamous cell carcinoma (OSCC) in a range of 1% to 2% of cases. Chronic alcohol consumption is associated with carcinogenesis, but its mechanism has not yet been fully elucidated. ALDH1A1 and 2, isoenzymes responsible for aldehyde oxidation involved in ethanol metabolism may be associated with the development of malignant head and neck neoplasms. The aim of this study was to analyze the expression of ALDH1A1 and ALDH2 in oral leukoplakia with epithelial dysplasia (OLP) and OSCC. A retrospective study was conducted on 27 cases of OLP and 30 cases of OSCC. Clinical data were obtained from medical records, and all cases were classified as mild, moderate, and severe for OLP, and well-differentiated, moderately differentiated, or poorly differentiated for OSCC cases. The ALDH1A1 and ALDH2 expression in OLP and OSCC was evaluated by the immunohistochemical technique. There was predominance of the male sex, in both OLP and OSCC cases. Oral tongue was the most affected site in both groups. OLP showed positive protein expression of ALDH1A1 in all cases, both basal and suprabasal epithelial layers, whereas ALDH2 showed less protein expression. In OSCC, the immunohistochemical reaction for ALDH1A1 expression was negative in 70%, whereas ALDH2 expression was positive in all cases. This study demonstrated the gradual loss of ALDH1A1 expression in OSCC in comparison with OLP, and the increased ALDH2 expression in OSCC.

PMID- 29189263 TI - B7-H4 is Inversely Correlated With T-Cell Infiltration in Clear Cell but Not Serous or Endometrioid Ovarian Cancer. AB - B7-H4, a tumor-associated cell surface protein, is expressed in endometrioid (EM), serous (SE), and clear cell (CC) ovarian carcinomas. Prior in vitro studies from other groups indicated that elevated B7-H4 expression by tumor cells blocks T-cell activation; therefore, it had been postulated to play a role in shielding cancer cells from immune surveillance and averting apoptotic programs. To test the validity of these hypotheses, the present study was designed to compare the immunohistochemical staining intensity of B7-H4 in tumor cells of ovarian cancers with the number of tumor-infiltrating T cells and macrophages and with the levels of caspase-3 staining in apoptotic debris. Serial tissue sections from EM, SE, and CC carcinomas were analyzed across representative cross-sections of tumor resection specimens, demonstrating different levels of B7-H4 expression, highest in CC cancers. B7-H4 staining in CC tissue sections was significantly correlated with the number of CD3, CD4, and CD8 tumor-infiltrating T cells and with the number of CD14 tumor-infiltrating macrophages, but was not significantly related to caspase-3 staining. These results support the concept that high levels of B7 H4 expression are inversely correlated with tumor T-cell infiltration and with CD14-labeled macrophages but not caspase-3 expression in CC carcinomas. We did not, however, find clear evidence of a relationship between the lower levels of B7-H4 seen in EM and SE carcinomas and T cell or macrophage infiltration. Thus, high levels of B7-H4, as seen in CC carcinomas, is associated with decreased tumor infiltration by T cells and macrophages but the lower levels of expression, as observed in EM and SE carcinomas, appear less likely to play an effective role in protection from immune surveillance. Furthermore, we found no evidence of a correlation between B7-H4 expression and apoptosis. These findings highlight the importance of further investigation of B7-H4 as an immunomodulatory protein, to support the development of novel therapeutic interventions for improved efficacy of treatments for CC carcinoma. PMID- 29189264 TI - Dendritic Cell Markers and PD-L1 are Expressed in Mediastinal Gray Zone Lymphoma. AB - AIMS: Mediastinal gray zone lymphoma (MGZL) is a rare entity with morphologic, immunophenotypic, and genetic features intermediate between classic Hodgkin lymphoma (CHL) and primary mediastinal large B-cell lymphoma (PMBL). It is challenging to differentiate from CHL and PMBL. A specific dendritic cell gene expression profile can distinguish CHL and MGZL from PMBL. We hypothesized that the dendritic markers fascin and CD123 may be helpful in distinguishing MGZL from CHL and PMBL. We also investigated programmed death-ligand 1 (PD-L1) expression in MGZL, which may have therapeutic significance in this difficulty to treat tumor. METHODS: Representative sections from 89 CHL, 20 PMBL, and 7 MGZL cases were stained for fascin, CD123, and PD-L1, and scored on a scale from 0 to 3+. Most (71%) MGZLs stained for CD123, as well as some (23%) CHLs, and few (11%) PMBLs. All MGZLs stained for fascin, as well as most (90%) CHLs, and approximately half (53%) of the PMBLs. PD-L1 was positive in all MGZLs, most (77%) CHLs and most (66%) PMBLs. CONCLUSIONS: Our study is the first to show CD123 is positive in a subset of formalin-fixed, paraffin-embedded MGZLs and CHLs, in contrast to PMBL which is largely negative. Staining for fascin was not significantly different between the lymphomas, but was less likely to be positive in PMBL. These findings suggest a role for CD123 and fascin in supporting diagnoses of MGZL and CHL, and in ruling out PMBL. By immunohistochemistry, PD-L1 is positive in MGZL, pointing to its therapeutic potential. PMID- 29189265 TI - Development of a Diagnostic Programmed Cell Death 1-Ligand 1 Immunohistochemistry Assay for Nivolumab Therapy in Melanoma. AB - Nivolumab is a monoclonal antibody that blocks the interaction between programmed cell death 1 (PD1) and programmed cell death 1-ligand 1 (PD-L1), resulting in enhanced antitumor activity by the immune system. Nivolumab is currently approved by the US Food and Drug Administration (FDA) for melanoma, non-small cell lung cancer (NSCLC), renal cell carcinoma, classical Hodgkin lymphoma, squamous cell carcinoma of the head and neck, and urothelial carcinoma. PD-L1 IHC 28-8 pharmDx is FDA-approved as a complementary diagnostic for immunohistochemical (IHC) detection of PD-L1 in non-squamous NSCLC and melanoma. We report validation of PD L1 IHC 28-8 pharmDx for PD-L1 detection on formalin-fixed, paraffin-embedded human melanoma specimens using Autostainer Link 48. A prevalence assessment of 104 melanoma specimens indicated that PD-L1 was detected across the full expression level range (0% to 100% of tumor cells). Assay robustness and precision studies were conducted at Agilent Technologies, with additional reproducibility studies performed at 3 external laboratories. Precision studies evaluated at >=1% and >=5% expression levels revealed a range of average negative agreement from 89.5%, 95% CI (83.2, 93.6) to 100%, 95% CI (97.3, 100), and average positive agreement from 85.5%, 95% CI (77.6, 90.9) to 100%, 95% CI (97.9, 100). For external reproducibility, precise results were obtained. These results demonstrate PD-L1 IHC 28-8 pharmDx is a precise, robust, and reproducible assay for determining PD-L1 expression in melanoma. This is the first PD-L1 IHC test to receive FDA approval as a complementary diagnostic in melanoma patients whereby positive PD-L1 expression is correlated with the magnitude of nivolumab treatment effect. PMID- 29189266 TI - Epidural Space Identification With Loss of Resistance Technique for Epidural Analgesia During Labor: A Randomized Controlled Study Using Air or Saline-New Arguments for an Old Controversy. AB - BACKGROUND: The best technique to identify the epidural space for labor analgesia is still unclear despite the publication of various randomized controlled studies and meta-analyses. Our aim was to assess the superiority of the saline loss of resistance (SLOR) technique over the air loss of resistance (ALOR) technique with respect to the quality of the block. METHODS: Consenting parturients admitted to our obstetric suite for spontaneous or induced labor were randomized to receive epidural analgesia using either the ALOR or SLOR technique. Our primary outcome was to compare the impact of the SLOR and ALOR technique on pain score improvement measured 30 minutes after administration of epidural block. Our secondary outcomes included the density of motor blockade and analgesic efficacy measured at 30 minutes. Primary and secondary outcomes were compared using the Student t test and Mann-Whitney U test. Statistical significance was set at P < .017 for primary and secondary outcomes, considering Bonferroni correction for multiple comparisons. Other comparisons were considered exploratory. RESULTS: Four hundred parturients were included; 24 were excluded from the final analysis. After 30 minutes, pain score reduction (ALOR, 4.7 +/- 2.9/10; SLOR, 4.9 +/- 3.0/10; P = .49), motor block (ALOR, 1.4 +/- 0.8; SLOR, 1.3 +/- 0.8; P = .27), and efficacy of the block (ALOR, 1.0 +/- 0.7; SLOR, 1.0 +/- 0.6; P = .87) did not differ significantly between groups. CONCLUSIONS: Pain score reduction after 30 minutes and onset of the block were not affected by the technique used to locate the epidural space. PMID- 29189267 TI - In Response.

AB - BACKGROUND: Currently, no reliable method exists for continuous, noninvasive measurements of absolute cerebral blood flow (CBF). We sought to determine how changes measured by ultrasound-tagged near-infrared spectroscopy (UT-NIRS) compare with changes in CBF as measured by transcranial Doppler (TCD) in healthy volunteers during profound hypocapnia and hypercapnia. METHODS: Ten healthy volunteers were monitored with a combination of TCD, UT-NIRS (c-FLOW, Ornim Medical), as well as heart rate, blood pressure, end-tidal PCO2 (PEtCO2), end tidal O2, and inspired O2. Inspired CO2 and minute ventilation were controlled to achieve 5 stable plateau goals of EtCO2 at 15-20, 25-30, 35-40, 45-50, and 55-60 mm Hg, for a total of 7 measurements per subject. CBF was assessed at a steady state, with the TCD designated as the reference standard. The primary analysis was a linear mixed-effect model of TCD and UT-NIRS flow with PEtCO2, which accounts for repeated measures. Receiver operating characteristic curves were determined for detection of changes in CBF. RESULTS: Hyperventilation (nadir PEtCO2 17.1 +/- 2.4) resulted in significantly decreased mean flow velocity of the middle cerebral artery from baseline (to 79% +/- 22%), but not a consistent decrease in UT-NIRS cerebral flow velocity index (n = 10; 101% +/- 6% of baseline). Hypercapnia (peak PEtCO2 59.3 +/- 3.3) resulted in a significant increase from baseline in both mean flow velocity of the middle cerebral artery (153% +/- 25%) and UT-NIRS (119% +/- 11%). Comparing slopes versus PEtCO2 as a percent of baseline for the TCD (1.7% [1.5%-2%]) and UT-NIRS (0.4% [0.3%-0.5%]) shows that the UT-NIRS slope is significantly flatter, P < .0001. Area under the receiver operating characteristic curve was significantly higher for the TCD than for UT-NIRS, 0.97 (95% confidence interval, 0.92-0.99) versus 0.75 (95% confidence interval, 0.66-0.82). CONCLUSIONS: Our data indicate that UT-NIRS cerebral flow velocity index detects changes in CBF only during hypercarbia but not hypocarbia in healthy subjects and with much less sensitivity than TCD. Additional refinement and validation are needed before widespread clinical utilization of UT-NIRS. PMID- 29189270 TI - Not All Calcium Formulations Are Alike. PMID- 29189271 TI - Low- Versus High-Chloride Content Intravenous Solutions for Critically Ill and Perioperative Adult Patients: A Systematic Review and Meta-analysis. AB - BACKGROUND: To assess whether use of low-chloride solutions in unselected critically ill or perioperative adult patients for maintenance or resuscitation reduces mortality and renal replacement therapy (RRT) use when compared to high chloride fluids. METHODS: Systematic review and meta-analysis with random-effects inverse variance model. PubMed, Cochrane library, EMBASE, LILACS, and Web of Science were searched from inception to October 2016. Published and unpublished randomized controlled trials in any language that enrolled critically ill and/or perioperative adult patients and compared a low- to a highchloride solution for volume maintenance or resuscitation. The primary outcomes were mortality and RRT use. We conducted trial sequential analyses and assessed risk of bias of individual trials and the overall quality of evidence. Fifteen trials with 4067 patients, most at low risk of bias, were identified. Of those, only 11 and 10 trials had data on mortality and RRT use, respectively. A total of 3710 patients were included in the mortality analysis and 3724 in the RRT analysis. RESULTS: No statistically significant impact on mortality (odds ratio, 0.90; 95% confidence interval, 0.69-1.17; P = .44; I = 0%) or RRT use (odds ratio, 1.12; 95% confidence interval, 0.80-1.58; P = .52; I = 0%) was found. Overall quality of evidence was low for both primary outcomes. Trial sequential analyses highlighted that the sample size needed was much larger than that available for properly powered outcome assessment. CONCLUSIONS: The current evidence on low- versus high chloride solutions for unselected critically ill or perioperative adult patients demonstrates no benefit, but suffers from considerable imprecision. We noted a limited exposure volume for study fluids and a relatively low risk of the populations in each study. Together with the relatively small pooled sample size, these data leave us underpowered to detect potentially important differences. Results from well-conducted, adequately powered randomized controlled trials examining sufficiently large fluid exposure are necessary. PMID- 29189272 TI - In Response. PMID- 29189273 TI - Two-Year Follow-up Survey: Views of US Anesthesiologists About Health Care Costs and Future Practice Roles. AB - Anesthesiologists' perspectives on US health care finance reform are increasingly germane to recent policy reforms. The aim of this follow-up survey was to examine how anesthesiologists' views of health care costs and future practice roles have changed since 2014. Six thousand randomly chosen active members of the American Society of Anesthesiologists were again surveyed and were also asked several new questions regarding specialties and perioperative management. Results showed an increase in self-reported understanding of the perioperative surgical home. Government, insurance companies, and pharmaceutical companies saw an increase in perceived "major responsibility" for cost reduction. Respondents vastly preferred that patient care under the perioperative surgical home be multidisciplinary. PMID- 29189274 TI - Lung Isolation in the Patient With a Difficult Airway. AB - One-lung ventilation is routinely used to facilitate exposure for thoracic surgical procedures and can be achieved via several lung isolation techniques. The optimal method for lung isolation depends on a number of factors that include (1) the indication for lung isolation, (2) anatomic features of the upper and lower airway, (3) availability of equipment and devices, and (4) the anesthesiologist's proficiency and preferences. Though double-lumen endobronchial tubes (DLTs) are most commonly utilized to achieve lung isolation, the use of endobronchial blockers offer advantages in patients with challenging airway anatomy. Anesthesiologists should be familiar with existing alternatives to the DLT for lung isolation and alternative techniques for DLT placement in the patient with a difficult airway. Newer technologies such as videolaryngoscopy with or without adjunctive fiberoptic bronchoscopy may facilitate intubation and lung isolation in difficult airway management. PMID- 29189275 TI - Ultrasound-Assisted Versus Fluoroscopic-Guided Lumbar Sympathetic Ganglion Block: A Prospective and Randomized Study. AB - BACKGROUND: Fluoroscopy (FL)-guided lumbar sympathetic ganglion block (LSGB) is widely performed to diagnose and manage various diseases associated with sympathetically maintained pain. Recently, numerous ultrasound (US)-assisted procedures in pain medicine have been attempted, showing an advantage of low radiation exposure. This randomized, prospective trial compared the procedural outcomes and complications between FL-guided and US-assisted LSGBs. METHODS: Fifty LSGBs were randomly divided into 2 groups: FL-guided (FL group) or US assisted (US group) LSGB group. Both groups received FL-guided or US-assisted LSGB with 10 mL of 0.25% levobupivacaine. The primary end point was the total procedure time. Secondary outcomes were success rate, imaging time, onset time (based on temperature rise), dosage of radiation exposure, other procedure related outcomes, and complications. RESULTS: Total procedure time and success rate were not statistically different between the 2 groups, whereas imaging time of the US group was longer than that of the FL group (P = .012). The onset time was faster in the US group (P = .019), and bone touching during the procedure was less frequent in the US group (P = .001). Moreover, radiation exposure was significantly lower in the US group than in the FL group (P < .001). No serious complications were reported in all patients. CONCLUSIONS: US-assisted LSGB appears to be a feasible method with the added benefit of lower radiation exposure. In our study, we did not find an advantage of US-assisted LSGB over FL guided LSGB in terms of performance time. PMID- 29189276 TI - Perioperative Noninvasive Blood Pressure Monitoring. AB - The most commonly monitored variable for perioperative hemodynamic management is blood pressure. Several indirect noninvasive blood pressure monitoring techniques have been developed over the last century, including intermittent techniques such as auscultation (Riva-Rocci and Korotkoff) and oscillometry (Marey) and continuous techniques. With the introduction of automated noninvasive blood pressure devices in the 1970s, the oscillometric technique quickly became and remains the standard for automated, intermittent blood pressure measurement. It tends to estimate more extreme high and low blood pressures closer to normal than what invasive measurements indicate. The accuracy of the oscillometric maximum amplitude algorithm for estimating mean arterial pressure is affected by multiple factors, including the cuff size and shape, the shape of the arterial compliance curve and arterial pressure pulse, and pulse pressure itself. Additionally, the technique typically assumes a consistent arterial compliance and arterial pressure pulse, thus changes in arterial compliance and arrhythmias that lead to variation in the pressure pulse can affect accuracy. Volume clamping, based on the Penaz principle, and arterial tonometry provide continuous tracking of the arterial pressure pulse. The ubiquitous use of blood pressure monitoring is in contrast with the lack of evidence for optimal perioperative blood pressure targets. PMID- 29189278 TI - Reducing Maternal Mortality in Papua New Guinea: Contextualizing Access to Safe Surgery and Anesthesia. AB - Papua New Guinea has one of the world's highest maternal mortality rates with approximately 215 women dying per 100,000 live births. The sustainable development goals outline key priority areas for achieving a reduction in maternal mortality including a focus on universal health coverage with safe surgery and anesthesia for all pregnant women. This narrative review addresses the issue of reducing maternal mortality in Papua New Guinea by contextualizing the need for safe obstetric surgery and anesthesia within a structure of enabling environments at key times in a woman's life. The 3 pillars of enabling environments are as follows: a stable humanitarian government; a safe, secure, and clean environment; and a strong health system. Key times, and their associated specific issues, in a woman's life include prepregnancy, antenatal, birth and the postpartum period, childhood, adolescence and young womanhood, and the postchildbearing years. PMID- 29189279 TI - Alkalinized Lidocaine Preloaded Endotracheal Tube Cuffs Reduce Emergence Cough After Brief Surgery: A Prospective Randomized Trial. AB - BACKGROUND: Alkalinized lidocaine in the endotracheal tube (ETT) cuff decreases the incidence of cough and throat pain on emergence after surgery lasting more than 2 hours. However, alkalinized lidocaine needs 60-120 minutes to cross the ETT cuff membrane; therefore, its usefulness in shorter duration surgery is unknown. This prospective double-blind randomized controlled trial tested the hypothesis that alkalinized lidocaine would reduce the incidence of emergence cough after surgeries lasting <120 minutes. METHODS: After local ethics board approval, American Society of Anesthesiologists I-III patients consented to be randomized into 1 of 2 groups receiving either alkalinized lidocaine (group AL) or saline (group S) to inflate the ETT cuff. Cuffs were prefilled >90 minutes before intubation with either 2 mL of 2% lidocaine and 8 mL of 8.4% bicarbonate (group AL) or 10 mL of normal saline (group S). Cuffs were emptied immediately before intubation. After intubation, either 2 mL of 2% lidocaine (AL) or 2 mL of saline (S) were injected into the cuff. Additional 8.4% bicarbonate (AL) or saline (S) was injected into the cuff until there was no air leak. Anesthesia was maintained using desflurane, rocuronium, and either fentanyl or sufentanil to maintain vital signs within 20% of baseline values. Opioids administered in prophylaxis of extubation cough were proscribed. A standardized "no touch" emergence technique was used. A blinded assessor noted any cough above 0.2 minimum alveolar concentration (MAC) of expired desflurane. At 0.2 MAC, once every 30 seconds, the patient was instructed to open his eyes and extubation occurred once a directed response was noted. RESULTS: A total of 213 patients were randomized and 100 patients in each group completed the experimental protocol. The incidence of extubation cough in group AL was 12%, significantly lower (1-sided P = .045) than the 22% incidence in group S. The 1-tailed risk ratio for cough in group AL was 0.55 (0-0.94, P = .045). Total amount of opioids administered (P = .194), ETT cuff preloading times (P = .259), and extubation times (P = .331) were not significantly different between groups. The average duration of surgery was 59 +/- 28 minutes in group AL and 52 +/- 29 minutes in group S (P = .057). CONCLUSIONS: Alkalinized lidocaine in the ETT cuff significantly decreased general anesthesia emergence cough after surgeries with an average duration of slightly <1 hour. PMID- 29189280 TI - The Science of Local Anesthesia: Basic Research, Clinical Application, and Future Directions. AB - Local anesthetics have been used clinically for more than a century, but new insights into their mechanisms of action and their interaction with biological systems continue to surprise researchers and clinicians alike. Next to their classic action on voltage-gated sodium channels, local anesthetics interact with calcium, potassium, and hyperpolarization-gated ion channels, ligand-gated channels, and G protein-coupled receptors. They activate numerous downstream pathways in neurons, and affect the structure and function of many types of membranes. Local anesthetics must traverse several tissue barriers to reach their site of action on neuronal membranes. In particular, the perineurium is a major rate-limiting step. Allergy to local anesthetics is rare, while the variation in individual patient's response to local anesthetics is probably larger than previously assumed. Several adjuncts are available to prolong sensory block, but these typically also prolong motor block. The 2 main research avenues being followed to improve action of local anesthetics are to prolong duration of block, by slow-release formulations and on-demand release, and to develop compounds and combinations that elicit a nociception-selective blockade. PMID- 29189281 TI - Improvement of the Elevated Tryptase Criterion to Discriminate IgE- From Non-IgE Mediated Allergic Reactions. AB - BACKGROUND: Differentiating between immunoglobulin E (IgE)-dependent and IgE independent hypersensitivity reactions may improve the etiologic orientation and clinical management of patients with allergic reactions in the anesthesia setting. Serum tryptase levels may be useful to discriminate the immune mechanism of allergic reactions, but the diagnostic accuracy and optimal cutpoint remain unclear.We aimed to compare the diagnostic accuracy of tryptase during reaction (TDR) alone and the TDR/basal tryptase (TDR/BT) ratio for discriminating IgE- from non-IgE-mediated allergic reactions, and to estimate the best cut point for these indicators. METHODS: We included 111 patients (45% men; aged 3-99 years) who had experienced an allergic reaction, even though the allergic reaction could be nonanaphylactic. Allergy tests were performed to classify the reaction as an IgE- or non-IgE-mediated one. The area under the curve (AUC) of the receiver operating characteristic analysis was performed to estimate the discriminative ability of TDR and TDR/BT ratio. RESULTS: An IgE-mediated reaction was diagnosed in 49.5% of patients, of whom 56% met anaphylaxis criteria. The median (quartiles) TDR for the IgE-mediated reactions was 8.0 (4.9-19.6) and 5.1 (3.5 8.1) for the non-IgE-mediated (P = .022). The median (quartiles) TDR/BT ratio was 2.7 (1.7-4.5) in IgE-mediated and 1.1 (1.0-1.6) in non-IgE-mediated reactions (P < .001). The TDR/BT ratio showed the greatest ability to discriminate IgE- from non-IgE-mediated reactions compared to TDR (AUC TDR/BT = 0.79 [95% confidence interval (CI), 1.1-2.2] and AUC TDR = 0.66 [95% CI, 1.1-2.2]; P = .003). The optimal cut point for TDR/BT (maximization of the sum of the sensitivity and specificity) was 1.66 (95% CI, 1.1-2.2). CONCLUSIONS: The TDR/BT ratio showed a significantly better discriminative ability than TDR to discriminate IgE- from non-IgE-mediated allergic reactions. An optimal TDR/BT ratio threshold of approximately 1.66 may be useful in clinical practice to classify allergic reactions as IgE- or non-IgE-mediated. PMID- 29189282 TI - Anesthesia Medication Handling Needs a New Vision. PMID- 29189283 TI - Effects of Increasing Airway Pressures on the Pressure of the Endotracheal Tube Cuff During Pelvic Laparoscopic Surgery. AB - BACKGROUND: Tracheal tube cuff pressures exceeding the perfusion pressures of the tracheal mucosa have been associated with complications such as sore throat, tracheal mucosa ulcers, tracheal rupture, and subglottic stenosis. Despite appropriate inflation, many factors can increase the tracheal cuff pressure during mechanical ventilation. This prospective observational cohort study was designed to test the hypothesis that during a clinical model of decreasing respiratory compliance, the pressure within the endotracheal tube cuff will rise in direct relationship to increases in the airway pressures. METHODS: Twenty eight adult obese patients (BMI >=30 kg/m) scheduled for elective laparoscopic gynecologic procedures were enrolled. All patients received general anesthesia utilizing endotracheal tubes with low-pressure high-volume cuffs. After baseline adjustment of the cuff pressure to 25 cm H2O, the airway pressures and endotracheal cuff pressures were continuously measured using pressure transducers connected to the anesthesia circuit and cuff pilot, respectively. Data on cuff and airway pressures, mechanical ventilation parameters, intraabdominal pressures, and degree of surgical table inclination were collected throughout the anesthetic procedure. General linear regression models with fixed and random effects were fit to assess the effect of increases in airway pressures on cuff pressure, after adjusting for covariates and the clustered structure of the data. RESULTS: The mean (standard deviation) age and body mass index were 42.2 (8.8) years and 37.7 (5.1) kg/m, respectively. After tracheal intubation, the cuffs were overinflated (ie, intracuff pressures >30 cm H2O) in 89% of patients. The cuff pressures significantly changed after concomitant variations in the airway pressures from a mean (standard error) value of 29.6 (1.30) cm H2O before peritoneal insufflations, to 35.6 (0.68) cm H2O after peritoneal insufflation, and to 27.8 (0.79) cm H2O after peritoneal deflation (P < .0001). The multilevel mixed regression models revealed that after controlling for clustering of the data (at the patient and study phase levels) and covariates, increased peak airway pressures were significantly associated with increased pressures within the endotracheal cuff (coefficient [95% confidence interval], 0.25 [0.14-0.36]; P < .0001). Other variables associated with increasing endotracheal cuff pressure included degree of surgical table inclination (0.08 [0.04-0.12]; P = .0003) and I:E ratio of 1:1 (4.47 [2.10-6.83]; P = .0002). CONCLUSIONS: This clinical model of decreased respiratory compliance in mechanically ventilated patients reveals that the pressure within the endotracheal cuff significantly changes in direct relation to changes in the airway pressures. This finding may have clinical relevance in patients requiring prolonged use of high airway pressures. PMID- 29189287 TI - Pharmacological considerations in the elderly. AB - PURPOSE OF REVIEW: This review discusses the pharmacology of contemporary anesthetic medications in geriatric patients, neurophysiological changes with aging, current recommendations for dosing anesthetic drugs. It also addresses current practice patterns and ongoing studies, which are likely to affect future anesthetic drug management in the elderly. RECENT FINDINGS: Potency of anesthetic drugs is increased in the elderly. In addition to changes at the receptor level, neurophysiological changes in functional connectivity with aging contributes to increased sensitivity of anesthetic drugs. However, the extent of reduction is underappreciated by the practitioners and dose adjustment is not uniformly applied in practice. Large database studies demonstrate association of short-term intraoperative hypotension and CNS depression, to poor perioperative outcomes. These perturbations are probably of greater consequence in frail, elderly patients with reduced reserves. SUMMARY: Anesthetic dosing should be more closely age-adjusted to prevent anesthetic-induced hypotension and increased depth of anesthesia in the elderly. Pharmacologic studies are required in the elderly population (>80 years). PMID- 29189288 TI - Clinicopathologic and Molecular Characteristics of Mesonephric Adenocarcinoma Arising From the Uterine Body. AB - Mesonephric adenocarcinoma (MNAC) is a rare tumor of the female genital tract mainly occurring in the uterine cervix. To date, only a few cases of MNAC arising from of the uterine body (UB-MNAC) have been reported. The clinicopathologic and molecular characteristics of UB-MNAC remain unknown. In this study, we investigated the clinical, histopathologic, immunohistochemical, and genetic features of UB-MNAC. In total, 11 cases were included. Six patients developed metastatic disease, most commonly in lungs (5/6). Histopathologically, UB-MNAC was characterized by an admixture of tubular, glandular, papillary, retiform, glomeruloid, sex cord-like, and comedonecrosis-like architectural patterns. Three adverse pathologic characteristics, including advanced International Federation of Gynecology and Obstetrics stage, high mitotic activity, and presence of lymphovascular the invasion, were independent factors predicting the development of metastasis. All cases were positive for GATA-binding protein 3 and paired box 2 expression and showed wild-type p53, patchy p16, and preserved PTEN expression, as indicated by immunohistochemistry. Next-generation sequencing using 12 samples (11 primary tumors and 1 metastatic tumor) revealed 42 single nucleotide variations in 16 genes, mostly in KRAS (10/12) and ARID1A (9/12). Copy number variation was found in 16 genomic regions, and consisted of 57 gains and 10 losses, with 1q gain (11/12) being the most prevalent. In conclusion, UB-MNAC displays an aggressive biological behavior, with a tendency to metastasize to the lungs. Adverse pathologic characteristics reflect the aggressive nature of UB MNAC. Distinct molecular features of UB-MNAC include frequent somatic mutations of KRAS and ARID1A and gain of 1q.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 29189289 TI - Meibomian Glands and Ocular Surface Changes After Closure of Meibomian Gland Orifices in Rabbits. AB - PURPOSE: To investigate changes in the corneal surface, tear film, and meibomian glands after meibomian gland orifice closure. METHODS: Seventy-two eyes of 36 rabbits were used. In the study group (n = 36), the meibomian gland orifices of both upper and lower eyelids in the right eyes were electrosurgically coagulated. The 36 untreated left eyes were used as controls. Corneal wetting properties were measured 1, 3, 7, and 14 days after coagulation. The eyelid sections were stained with anti-cytokeratin (CK)1, CK5, and CK6 antibody 8 weeks after coagulation. The area of the secretory acini around one meibomian gland duct was measured, and meibography of rabbits was performed 8 weeks after meibomian gland orifice closure. RESULTS: Three days after coagulation, the corneal wetting property was decreased compared with controls. The meibomian gland ducts gradually dilated in the study group over time. The epithelium of the central ducts in both groups was stained with CK5 and CK6, but not CK1. Although the mean area of the secretory acini in the study group (0.10 +/- 0.04 mm) was significantly smaller than that of the control group (0.18 +/- 0.04; P = 0.004), meibography showed normal morphology in both study and control groups. CONCLUSIONS: Meibomian gland orifice closure reduced corneal wetting property and induced meibomian gland duct dilation accompanied by shrinkage of secretory acini. Meibography could not detect early changes in the meibomian gland after closure of the orifice. Therefore, when the orifice is obstructed, more active treatments are needed before structural changes occur. PMID- 29189291 TI - Effect of Thoracic Epidural Ropivacaine versus Bupivacaine on Lower Urinary Tract Function: A Randomized Clinical Trial. AB - BACKGROUND: Thoracic epidural analgesia with bupivacaine resulted in clinically relevant postvoid residuals due to detrusor underactivity. This study aimed to compare the risk of bladder dysfunction with ropivacaine versus bupivacaine using postvoid residuals and maximum flow rates. Our hypothesis was that ropivacaine would result in lower postvoid residuals, because ropivacaine has been shown to have less effect on motor blockade. METHODS: In this single-center, parallel group, randomized, double-blind superiority trial, 42 patients undergoing open renal surgery were equally allocated to receive epidural bupivacaine 0.125% or ropivacaine 0.2%, and 36 were finally included. Inclusion criterion was normal bladder function. Patients underwent urodynamic investigations preoperatively and during thoracic epidural analgesia. Primary outcome was the difference in postvoid residual preoperatively and during thoracic epidural analgesia postoperatively. Secondary outcomes were changes in maximum flow rate between and within the groups. RESULTS: Median difference in postvoid residual (ml) from baseline to postoperatively was 300 (range, 30 to 510; P < 0.001) for bupivacaine and 125 (range, -30 to 350; P = 0.011) for ropivacaine, with a significant mean difference between groups (-175; 95% CI, -295 to -40; P = 0.012). Median difference in maximum flow rate (ml/s) was more pronounced with bupivacaine (-12; range, -28 to 3; P < 0.001) than with ropivacaine (-4; range, -16 to 7; P = 0.025) with a significant mean difference between groups (7; 95% CI, 0 to 12; P = 0.028). Pain scores were similar. No adverse events occurred. CONCLUSIONS: Postvoid residuals were significantly lower using ropivacaine compared to bupivacaine for thoracic epidural analgesia reflecting less impairment of detrusor function with ropivacaine. PMID- 29189290 TI - Period-dependent Associations between Hypotension during and for Four Days after Noncardiac Surgery and a Composite of Myocardial Infarction and Death: A Substudy of the POISE-2 Trial. AB - BACKGROUND: The relative contributions of intraoperative and postoperative hypotension to perioperative morbidity remain unclear. We determined the association between hypotension and a composite of 30-day myocardial infarction and death over three periods: (1) intraoperative, (2) remaining day of surgery, and (3) during the initial four postoperative days. METHODS: This was a substudy of POISE-2, a 10,010-patient factorial-randomized trial of aspirin and clonidine for prevention of myocardial infarction. Clinically important hypotension was defined as systolic blood pressure less than 90 mmHg requiring treatment. Minutes of hypotension was the exposure variable intraoperatively and for the remaining day of surgery, whereas hypotension status was treated as binary variable for postoperative days 1 to 4. We estimated the average relative effect of hypotension across components of the composite using a distinct effect generalized estimating model, adjusting for hypotension during earlier periods. RESULTS: Among 9,765 patients, 42% experienced hypotension, 590 (6.0%) had an infarction, and 116 (1.2%) died within 30 days of surgery. Intraoperatively, the estimated average relative effect across myocardial infarction and mortality was 1.08 (98.3% CI, 1.03, 1.12; P < 0.001) per 10-min increase in hypotension duration. For the remaining day of surgery, the odds ratio was 1.03 (98.3% CI, 1.01, 1.05; P < 0.001) per 10-min increase in hypotension duration. The average relative effect odds ratio was 2.83 (98.3% CI, 1.26, 6.35; P = 0.002) in patients with hypotension during the subsequent four days of hospitalization. CONCLUSIONS: Clinically important hypotension-a potentially modifiable exposure-was significantly associated with a composite of myocardial infarction and death during each of three perioperative periods, even after adjustment for previous hypotension. PMID- 29189292 TI - Closed-Set Speech Discrimination Tests for Assessing Young Children. AB - OBJECTIVE: The main objective of this study is to obtain data assessing normative scores, test-retest reliability, critical differences, and the effect of age for two closed-set consonant-discrimination tests. DESIGN: The two tests are intended for use with children aged 2 to 8 years. The tests were evaluated using normal hearing children within the appropriate age range. The tests were (1) the closed set consonant confusion test (CCT) and (2) the consonant-discrimination subtest of the closed-set Chear Auditory Perception Test (CAPT). Both were word identification tests using stimuli presented at a low fixed level, chosen to avoid ceiling effects while avoiding the use of background noise. Each test was administered twice. RESULTS: All children in the age range 3 years 2 months to 8 years 11 months gave meaningful scores and were able to respond reliably using a computer mouse or a touch screen to select one of four response options displayed on a screen for each trial. Assessment of test-retest reliability showed strong agreement between the two test runs (interclass correlation >= 0.8 for both tests). The critical differences were similar to those for other monosyllabic speech tests. Tables of these differences for the CCT and CAPT are provided for clinical use of the measures. Performance tended to improve with increasing age, especially for the CCT. Regression equations relating mean performance to age are given. CONCLUSIONS: The CCT is appropriate for children with developmental age in the range 2 to 4.5 years and the CAPT is appropriate as a follow-on test from the CCT. If a child scores 80% or more on the CCT, they can be further tested using the CAPT, which contains more advanced vocabulary and more difficult contrasts. This allows the assessment of consonant perception ability and of changes over time or after an intervention. PMID- 29189293 TI - Mechanisms of rejection in vascular composite allotransplantation. AB - PURPOSE OF REVIEW: For patients with devastating injuries in whom standard reconstruction is not an option, vascularized composite allotransplantation (VCA) has become a viable means of restoring form and function. However, immunological rejection continues to be a problem in VCA and has not yet been fully characterized. As the field is relatively new, much of the data on rejection and immunosuppression have been extrapolated from that of solid organ transplantation. In this review, we cover the basic mechanisms of rejection as they relate specifically to VCA with analysis of recent literature and future directions. RECENT FINDINGS: Recent clinical studies have supported previously postulated T-cell-mediated mechanism of acute rejection and have also made strides in differentiating rejection from inflammation from other skin conditions and with different treatment regimens. Antibody-mediated rejection has been described in recent cases as well as treatment of presensitized patients receiving VCAs. With more long-term grafts, chronic changes, including vasculopathy, are being reported. SUMMARY: Clinically observed types of rejection in VCA include mainly cell-mediated, antibody-mediated and chronic rejection. Advances in diagnosis and treatment of rejection have been made, but there is still much to be learned about VCA-specific rejection. PMID- 29189294 TI - Using Choice Architecture to Integrate Substance Use Services with Primary Care: Commentary on Donohue et al. (2017). AB - : At a time when death and disability linked to problematic substance use have reached crisis levels, integration of substance use disorder (SUD) services into primary care settings is a clear national priority. Incentive-based interventions can catalyze such adoption, but have thus far demonstrated limited efficaciousness. Behavioral Economics can inform efforts to incentivize healthcare providers to adopt SUD interventions. Choice architecture principles dictate pegging rewards to defined quality metrics, improving provider information about effective and cost-effective practices, and reducing barriers to SUD service provision through technological tools, tackling stigma, and addressing real and perceived regulatory burdens and risks. Additional research is needed to inform these and other key elements in the choice environment designed to facilitate the integration of SUD care into primary care. Success in the deployment of the "cascade of care" model in primary care settings during the HIV/AIDS epidemic provides room for optimism, but also underscores the urgency of rapid scale-up in diagnostic and treatment services for SUD to address the burgeoning opioid crisis.

AB - OBJECTIVES: The Alternative Quality Contract (AQC) implemented in 2009 by Blue Cross Blue Shield of Massachusetts (BCBSMA) is intended to improve quality and control costs by putting providers at risk for total medical spending and tying payment to performance on specified quality measures. We examined the AQC's early effects on use of and spending on medication treatment (MT) for addiction among individuals with alcohol use disorders (AUDs) and opioid use disorders (OUDs), conditions not subject to any performance measurement in the AQC. METHODS: Using data from 2006 to 2011, we use difference-in-difference estimation of the effect of the AQC on MT using a comparison group of enrollees in BCBSMA whose providers did not participate in the AQC. We compared AQC and non-AQC enrollees with AUDs (n = 37,113 person-years) and/or OUDs (n = 12,727 person-years) on any use of MT, number of prescriptions filled, and MT spending adjusting for demographic and health status characteristics. RESULTS: There was no difference in MT use among AQC enrollees with OUD (38.7%) relative to the comparison group (39.1%) (adjusted difference = -0.4%, 95% confidence interval -3.8% to 3.0%, P = 0.82). Likewise, there was no difference in MT use for AUD between the AQC (6.3%) and comparison group (6.5%) (P = 0.64). Similarly, we detected no differences in number of prescriptions or spending. CONCLUSIONS: Despite incentives for improved integration and quality of care under a global payment contract, the initial 3 years of the AQC showed no impact on MT use for AUD or OUD among privately insured enrollees with behavioral health benefits. PMID- 29189296 TI - Long-term outcome after the acute respiratory distress syndrome: different from general critical illness? AB - PURPOSE OF REVIEW: To review the current research data on long-term outcome and health-related quality of life in survivors of the acute respiratory distress syndrome (ARDS) and to compare these findings with those from non-ARDS patients surviving critical illness. RECENT FINDINGS: Between 6 months and 2 years after discharge from ICU, survivors of ARDS present with substantial impairments of the levels of body function (muscle strength, walking capacity and/or physical activity (physical SF-36 score). In contrast to non-ARDS patients from surgical ICUs, a standardized intensified physical therapy during early course of illness in ARDS patients could not show an improvement of long-term physical function performance. Furthermore, a substantial part of further ARDS patients suffer from depression (26-33%), anxiety (38-44%) or posttraumatic stress disorder (22-24%). In general, the level of functional autonomy and daily life activities was reduced, and in one study, 6 months after ICU-discharge this level was significantly lower in ARDS patients compared with non-ARDS patients. In a recent study, 44% of ARDS survivors were jobless 1 year after critical illness, whereas half of previously employed patients returned to work within 4 months after hospital discharge. General health-related quality of life was significantly reduced compared with a matched population in all studies. SUMMARY: Surviving ARDS is associated with a long-term substantial reduction in health-related quality of life and such a reduction does not differ from findings in patients surviving other critical illness. In further research, a special attention should be paid to prevention measures of the 'post intensive care syndrome' as well as to patient important domains, which might better explain the patient's and families' demands. PMID- 29189297 TI - Are on-scene blood transfusions by a helicopter emergency medical service useful and safe? a multicentre case-control study. AB - INTRODUCTION: In the prehospital setting, crystalloid fluids are frequently used, but only erythrocytes are capable of transporting oxygen to tissues. The aim of this study was to establish the efficacy and safety of the prehospital use of uncross matched type O rhesus-negative packed red blood cells (URBC) by the Dutch physician-staffed helicopter emergency medical service. We hypothesized that prehospital URBC transfusions are safe and more effective with respect to survival than resuscitations with crystalloids. METHODS: The effects of prehospital URBC transfusions were studied by comparing a cohort of patients (>18 years) who were treated with a combination of URBC and crystalloid fluids with a matched control group of patients who received crystalloid fluids alone. RESULTS: Among 73 adults who received prehospital URBC transfusions, 50 (68%) patients were included. No transfusion reactions were observed. No effect of prehospital transfusion on 24-h or 30-day survival was found. Haemoglobin levels at presentation to the emergency department were higher in the URBC cohort. The two groups had similar cumulative erythrocyte requirements within the first 24 h. CONCLUSION: Neither survival benefits nor a decreased incidence of shock on admission were observed after prehospital helicopter emergency medical service URBC transfusions. There were no prehospital transfusion reactions in this study; therefore, URBC transfusions were deemed to be safe. A prospective randomized study is warranted to evaluate the effect of early URBC transfusions and transfusions with preheated URBC on the survival of patients with severe prehospital haemorrhagic shock. PMID- 29189298 TI - Laboratory examinations for the vestibular system. AB - PURPOSE OF REVIEW: In the last decades, researchers suggested that clinical assessment of labyrinthine function in detail became easy thanks to video head impulse tests (VHITs), vestibular evoked myogenic potential test (VEMP) and video oculography (VOG). It has been argued that they can replace electronystagmography, the caloric and rotatory chair tests. This review addresses the latest evaluations of these tests and the opportunities they offer, but also the limitations in clinical practice. RECENT FINDINGS: The VHIT and suppression head impulse test (SHIMP) are under ideal circumstances able to accurately identify deficits of the VOR in 3D. However, in a relevant part of the patient population, pupil tracking is inaccurate, video-goggles slip and VOR quantification is problematic. The dissociation between the VHIT and caloric test suggests that these tests are complementary. A new 3D-VOG technique claims to quantify eye torsion better than before, opening multiple diagnostic possibilities. VEMPs remain difficult to standardize. Variability in normal cervical vestibular-evoked myogenic potential amplitude is large. VEMPs become smaller or absent with age, raising questions of whether there is a lower normal limit at all. Recent research shows that the labyrinth is directly stimulated in the MRI offering new opportunities for diagnostics and research. SUMMARY: In clinical practice, the VHIT, SHIMP, VEMP and new 3D-VOG techniques improve diagnostic power. Unfortunately, technical issues or variability prevent reliable quantitative evaluation in a part of the regular patient population. The traditional caloric and rotatory chair test can still be considered as valuable complementary tests. PMID- 29189299 TI - Global orientation in space and the lateralization of brain functions. AB - PURPOSE OF REVIEW: The functional role of the vestibular system for multisensory orientation and sensorimotor control is reviewed with a special focus on hemispherical lateralization and its consequences for neurological disorders of higher cortical function. RECENT FINDINGS: The peripheral and central vestibular systems are bilaterally organized with ipsilateral and contralateral ascending pathways and two multisensory cortical networks in the right and left hemisphere. The vestibular cortical system shows a structural and functional lateralization with a dominance of the right hemisphere in right-handers and the left hemisphere in left-handers. Although the vestibular brainstem pathways are evenly distributed at lower pontine level, an increasing lateralization builds up because of an asymmetric number of pontine and mesencephalic crossing fibers from left to right in right-handers. This vestibular lateralization causes more frequent and more severe disorders of higher sensorimotor dysfunction in lesions of the right hemisphere such as in hemispatial neglect and the pusher syndrome. SUMMARY: There is evidence that multisensory higher vestibular functions including large-scale spatial orientation, spatial memory and navigation are dominated by the right temporo-parietal cortex. A beneficial result of lateralization of brain functions in healthy individuals is that it enables the individual to produce a global sensorimotor response even in case of a mismatch of the actual right and left sensory inputs. The consequence for neurology, however, is that lesions in the dominant hemisphere cause more frequently and more severe disorders such as the visuo-spatial hemineglect and the pusher syndrome.

PMID- 29189302 TI - Sex Differences in Neuropsychological Test Performance in Alzheimer's Disease and the Influence of the ApoE Genotype. AB - BACKGROUND: Only few studies exist reporting sex differences in the Alzheimer disease (AD) patients regarding cognitive profile, brain damage, and risk factors. The present study investigated the influence of sex in combination with the Alzheimer risk allele, epsilon4-allele of apolipoprotein E, on cognitive performance. MATERIALS AND METHODS: We examined the effect of sex and ApoE genotype on a range of neuropsychological markers from the German version of the Consortium to Establish a Registry in Alzheimer's Disease Neuropsychological Battery in a monocentric study of 399 AD patients. RESULTS: Male patients had significantly more years of school and occupational education compared with women. Male AD patients outperformed female patients in tasks of object naming, constructional praxis, and constructional praxis recall. There was no statistically significant interaction effect between sex and epsilon4-allele of apolipoprotein E for any of the examined variables. CONCLUSIONS: The superiority of healthy men compared with women in tasks of object naming, constructional praxis, and visual memory seems to remain stable when people develop AD, indicating larger cognitive reserves in men. In contrast, findings that cognitively healthy women outperform men in tests of verbal memory and verbal fluency are not stable in AD. Further studies are needed to gain insight in the reasons for sex differences. PMID- 29189301 TI - Assessing Fitness to Drive in Patients With Different Types of Dementia. AB - Dementia is a risk factor for unsafe driving. Therefore, an assessment strategy has recently been developed for the prediction of fitness to drive in patients with the Alzheimer disease (AD). The aim of this study was to investigate whether this strategy is also predictive of fitness to drive in patients with non-AD dementia, that is, vascular dementia, frontotemporal dementia, and dementia with Lewy bodies. Predictors were derived from 3 types of assessment: clinical interviews, neuropsychological tests, and driving simulator rides. The criterion was the pass-fail outcome of an official on-road driving assessment. About half of the patients with non-AD dementia (n=34) failed the on-road driving assessment. Neuropsychological assessment [area under the curve (AUC)=0.786] was significantly predictive of fitness to drive in patients with non-AD dementia, however, clinical interviews (AUC=0.559) and driving simulator rides (AUC=0.404) were not. The fitness-to-drive assessment strategy with the 3 types of assessment combined (AUC=0.635) was not found to significantly predict fitness to drive in non-AD dementia. Different types of dementia require different measures and assessment strategies.

PMID- 29189304 TI - Interventional Pain Procedures in Physical Medicine and Rehabilitation Residencies. AB - Exposure to interventional pain procedures is now a required component of training in physical medicine and rehabilitation residencies as mandated by the Accreditation Council for Graduate Medical Education. Data regarding resident exposure and competency in these procedures remain limited. Objectives were to determine the volume and type of exposure physical medicine and rehabilitation residents have to interventional pain procedures and to obtain faculty-perceived opinions regarding competency of incoming fellows as it pertains to interventional pain management. Online surveys were sent to program directors of physical medicine and rehabilitation residencies and fellowship directors of interventional spine, sports medicine, and pain medicine fellowships. Surveys inquired about educational methods, the volume of procedures in which residents actively participate, and faculty-perceived competency of trainees performing procedures. Thirty-nine residency programs and 27 fellowships responded to the surveys. Of the 39 residencies that responded, there was great variation in the exposure residents receive. Most programs reported that residents have moderate exposure to common procedures such as ultrasound-guided knee injections and lumbar epidural injections. In addition, while most residency program directors report graduates to be "fairly prepared" (33%) to "well prepared" (20.5%) with regard to spine procedures, most fellowship directors (63%) describe incoming fellows to be at the "beginner" level. PMID- 29189305 TI - Rehabilitation Outcomes in Spinal Abscess Patients With and Without a History of Intravenous Substance Abuse. AB - OBJECTIVE: The aim of the study was to compare functional outcomes of acute inpatient rehabilitation for spinal epidural abscess patients with and without history of intravenous substance abuse. DESIGN: This is a retrospective case series study in freestanding rehabilitation hospital. METHODS: Charts of 28 spinal epidural abscess patients admitted from January 2012 to September 2015: 13 with intravenous substance abuse and 15 without intravenous substance abuse were reviewed. Both groups received standard-of-care rehabilitation. Statistical analyses of Functional Independence Measure scores were conducted using individual 2 (substance use) * 2 (rehabilitation status) repeated measures analysis of variance. Functional outcomes were defined by total Functional Independence Measure scores as well as motor and cognitive subsets. Length of stay and morphine equivalents were also compared. RESULTS: There were no significant differences between the two groups. There was a significant main effect of treatment on total Functional Independence Measure scores (P < 0.001), Functional Independence Measure motor scores (P < 0.001), and Functional Independence Measure cognitive scores (P < 0.01) from admission to discharge. Subsequent Student's t tests revealed that the scores of both groups significantly improved on all Functional Independence Measure components. There were no group differences on length of stay and morphine equivalents at discharge. CONCLUSIONS: Acute inpatient rehabilitation can effectively improve functional outcomes in spinal epidural abscess patients with or without intravenous substance abuse, even though these two patient groups can vary in clinical factors.

PMID- 29189306 TI - Does a Rehabilitation Program of Aerobic and Progressive Resisted Exercises Influence HIV-Induced Distal Neuropathic Pain? AB - OBJECTIVE: Distal symmetrical polyneuropathy is a common neurological sequela after HIV, which leads to neuropathic pain and functional limitations. Rehabilitation programs with exercises are used to augment pharmacological therapy to relieve pain but appropriate and effective exercises are unknown. This study explored the safety and effect of moderate-intensity aerobic exercises and progressive resisted exercises for HIV-induced distal symmetrical polyneuropathy neuropathic pain. DESIGN: A randomized pretest, posttest of 12 wks of aerobic exercise or progressive resisted exercise compared with a control. Outcome measures were assessed using the subjective periphery neuropathy, brief peripheral neuropathy screening, and numeric pain rating scale. Pain was assessed at baseline, 6 and 12 wks. Data between groups were compared using Kruskal Wallis, Mann-Whitney U test, and within-groups Friedman and Wilcoxon signed rank tests. RESULTS: There were 136 participants (mean [SD] age = 36.79 [8.23] yrs) and the exercise groups completed the protocols without any adverse effects. Pain scores within and between aerobic exercise and progressive resisted exercise groups showed significant improvement (P < 0.05) from baseline to 6 and 12 wks compared with the control (P > 0.05). CONCLUSIONS: This study supports a rehabilitation program of moderate-intensity aerobic exercise and progressive resisted exercise being safe and effective for reducing neuropathic pain and is beneficial with analgesics for HIV-induced distal symmetrical polyneuropathy. PMID- 29189308 TI - Lactotripeptides Supplementations Alleviate the Decrease in Maximal Isometric Force After High-Intensity Eccentric Exercise: A Randomized, Placebo-Controlled, Double-Blind Clinical Trial. AB - OBJECTIVE: The aim of the study was to investigate whether lactotripeptides supplementations alleviate the decrease in the maximal isometric force, an indirect marker of muscle damage, after eccentric exercise (ECC). DESIGN: Twenty two young men performed 50 ECC of the elbow flexors using an isokinetic dynamometer. The subjects were randomly assigned to either the placebo or lactotripeptides group and were each given a 4.5 mg/d placebo or lactotripeptides thrice on the exercise day and the day after. Maximal isometric force and brachial arterial diameter were assessed before and 2 days after the ECC. RESULTS: The interaction of time and group on maximal isometric force was significant (P < 0.05); maximal isometric force was significantly decreased in both groups after ECC (P < 0.005). The interaction of brachial arterial diameter was significant (P < 0.05); brachial arterial diameter was significantly increased in only the lactotripeptides group (P < 0.005). In addition, the change in maximal isometric force was significantly related to the change in brachial arterial diameter after adjusting for body weight and change in range of motion (P < 0.05). CONCLUSIONS: The present results suggest that lactotripeptides supplementation alleviates the decrease in the maximal isometric force via an increase in brachial arterial diameter after ECC.

PMID- 29189310 TI - Muscle Damage Due to Fusidic Acid-Statin Interaction: Review of 75 Cases From the French Pharmacovigilance Database and Literature Reports. AB - BACKGROUND/AREA OF UNCERTAINTY: Statins, which reduce cardiovascular risk in both primary and secondary prevention, are one of the most widely prescribed therapeutic classes in the world. Usually well-tolerated, statin-associated muscle symptoms are a well-known adverse effect. Fusidic acid (FA) is a bacteriostatic antibiotic of interest in the treatment of methicillin-resistant Staphylococcus aureus infections. Cases of rhabdomyolysis, sometimes fatal, have been reported after coprescription of FA and a statin. DATA SOURCES/AREA OF UNCERTAINTY: We studied 75 cases of muscle damage related to interaction between FA and a statin reported in the French national pharmacovigilance database (43 cases) and from a literature review (32 cases). RESULTS: Cases were mostly men (72.5%), often overweight (mean body mass index: 29.4). The most commonly reported statins were atorvastatin (60%), simvastatin (22.7%), and rosuvastatin (8.0%). Muscle disorders appeared on average 30 days after initiation of FA. Symptoms were muscle weakness (82%), dark urine (71%), and myalgia (61%). Mean creatine kinase level at diagnosis was 43,890 UI/mL, and acute renal injury occurred more than half of the cases. Outcome was fatal in 22% of cases and 28% kept sequelae at the end of the follow-up (54 days). CONCLUSIONS: Muscle damage induced by interaction between FA and statin is a potentially life-threatening complication, leading to contraindication of this association in France. This is to be reminded especially because FA is about to get FDA approval and should soon be available in the United States. PMID- 29189311 TI - Role of Preemptive Gabapentin on Postoperative Analgesia After Infraumbilical Surgeries Under Subarachnoid Block-A Randomized, Placebo-Controlled, Double-Blind Study. AB - BACKGROUND: Preemptive use of gabapentin might accelerate recovery by reducing acute post-inguinal herniorrhaphy pain and opioid requirement being an analgesic. STUDY QUESTION: Assessing efficacy of three different doses of oral gabapentin premedication for postoperative pain management after inguinal herniorrhaphy under spinal anesthesia. STUDY DESIGN: This prospective, randomized, placebo controlled study was performed on 120 male patients (ASA I/II) undergoing inguinal herniorrhaphy under subarachnoid block. Patients were divided into 4 groups of 30 patients each to receive placebo (group A) or gabapentin 400 mg (B) or 800 mg (C) or 1200 mg (D), administered orally 2 hours before surgery. Assessment of postoperative pain was made on the basis of the visual analog score (VAS), where 0 cm "no pain" and 10 cm "worst pain imaginable." Patients received IV fentanyl 0.5 MUg/kg bolus when VAS >3. MEASURES AND OUTCOMES: VAS score at regular intervals, the first analgesic requirement and total opioid consumption within 24 hours after surgery along with side/adverse effect (s) of study drug in perioperative period. RESULTS: The VAS of the study groups B, C, D were significantly lower than placebo group (A) at 0, 1, 2, 4, 8, 12, 16, 20, and 24 hour intervals after surgery (P < 0.05). The first analgesic need and total opioid consumption within 24 hours after surgery of study groups were significantly lower than placebo group (P < 0.005) while within study groups difference was not significant. Dizziness and somnolence were seen maximally in group D patients (P = 0.01). However, pruritus, nausea and vomiting though maximally reported among group (A) patients but statistically non-significant. CONCLUSION: Preemptive gabapentin is opioid sparing to control postoperative pain with anxiolysis and sedation. We found the optimal dose to be 400 mg for gabapentin. However, increasing dose from 400 to 1200 mg does not increase its efficacy as analgesic but with higher adverse effects. PMID- 29189312 TI - Hypoglycemia and Sudden Death During Treatment With Methadone for Opiate Detoxification. AB - CLINICAL FEATURES: We present a case of a middle-aged man admitted to an inpatient detoxification facility for withdrawal of intranasal heroin, alprazolam, and ethanol. The patient was placed on methadone and chlordiazepoxide tapers. Ondansetron and trazodone were prescribed as needed for symptom control. On the third hospital day, the patient was found unresponsive with blood glucose of 40 mg/dL. He had no history of glucose dysregulation. The patient was pronounced dead shortly thereafter. Methadone overdose was ruled the cause of death. THERAPEUTIC CHALLENGES: There have been studies linking methadone with glucose dysregulation. Hypoglycemia can induce changes in the electrical system in the heart, including lengthening QT interval, lengthening repolarization, and causing ST wave changes. In addition, there have been studies linking methadone treatment to QT interval prolongation and torsade de pointes. Ondansetron and trazodone have both been associated with cardiac conduction abnormalities. SOLUTION: We recommend initial blood glucose and cardiac monitoring in patients taking methadone 40 mg daily or higher. PMID- 29189313 TI - Vedolizumab-Associated Acute Respiratory Distress Syndrome.

PMID- 29189318 TI - Standardised noxious stimulation-guided individual adjustment of remifentanil target-controlled infusion to prevent haemodynamic responses to laryngoscopy and surgical incision: A randomised controlled trial. AB - BACKGROUND: The surgical plethysmographic index (SPI) is one of the available indexes of the nociception-antinociception (NAN) balance. Individually adjusting the NAN balance to prevent somatic responses to noxious stimulation remains a challenge. OBJECTIVES: To assess whether guiding remifentanil administration according to the SPI response to a calibrated noxious stimulus (NANCAL) can blunt the haemodynamic response to tracheal intubation and surgical incision. DESIGN: Randomised multicentre study. SETTING: Two Belgian university hospitals from January 2014 to April 2015. PATIENTS: After ethic review board approval and informed consent, 48 American Society of Anesthesiologists I or II adult patients scheduled for surgery under general anaesthesia were enrolled. INTERVENTIONS: Patients were randomly assigned to a SPI group, where remifentanil effect-site concentration was adjusted according to NANCAL, or a control group, where it was fixed at 4 ng ml. Propofol concentration was always adjusted to maintain the bispectral index close to 40. NANCAL consisted of a 100 Hz, 60 mA electrical tetanic stimulation during 30 s at the wrist before tracheal intubation and before surgical incision. MAIN OUTCOME MEASURES: The primary endpoint was the efficacy of the NANCAL-guided remifentanil administration to prevent the haemodynamic response to tracheal intubation and surgical incision. The secondary aim was to compare the ability of SPI, analgesia nociception index, pupil diameter and mean arterial pressure response to NANCAL to predict the haemodynamic response to tracheal intubation and surgical incision. RESULTS: Our SPI response to NANCAL-based correcting scheme for remifentanil administration was not superior to a fixed remifentanil concentration at blunting the haemodynamic response to tracheal intubation or surgical incision. Among all tested NAN balance indices, only mean arterial pressure had significant predictive ability with regard to the haemodynamic response to surgical incision. CONCLUSION: Further research is needed to define the best NANCAL stimulus and the best remifentanil correcting scheme to help individualised tailoring of antinociception for each specific subpopulation of surgical patients.

PMID- 29189325 TI - Oral Health and the Oral Microbiome in Pancreatic Cancer: An Overview of Epidemiological Studies. AB - PURPOSE: The aim was to provide a cohesive overview of epidemiological studies of periodontal disease, oral microbiome profiles, and pancreatic cancer risk. DESIGN: A PubMed search of articles published in English through July 2017 with additional review of bibliographies of identified articles. RESULTS: Risk estimates for periodontal disease associated with pancreatic cancer consistently ranged from 1.5 to 2, aligning with a meta-analysis summary relative risk of 1.74. Analyses of antibodies to pathogenic and/or commensal oral bacteria in prediagnostic blood provided evidence that some oral bacteria and oral microbial diversity may be related to pancreatic cancer. CONCLUSIONS: Overall, the data present a plausible but complex relationship among pancreatic cancer, the oral microbiome, periodontal disease, and other risk factors that might be explained by systemic effects on immune and inflammatory processes. Larger comprehensive studies that examine serially collected epidemiological/clinical data and blood, tissue, and various microbial samples are needed to definitively determine how and whether oral health-related factors contribute to pancreatic cancer risk. PMID- 29189326 TI - Advances in the Genetics and Biology of Pancreatic Cancer. AB - Pancreatic ductal adenocarcinoma (PDA) remains one of the most devastating diagnoses in modern medicine. While the clinical management of the disease has improved, the complex biologic underpinnings of PDA enable both its aggressive nature and slow clinical translational progress. In this review, we provide an overview of the key features of PDA genetics and biology, highlighting translational challenges and providing a framework for improved diagnostic and therapeutic approaches. PMID- 29189327 TI - The Pancreatic Cancer Microenvironment. AB - Pancreatic ductal adenocarcinoma (PDAC) is composed of a minority of malignant cells within a microenvironment of extracellular matrix, fibroblasts, endothelial cells, and immune cells. Therapeutic failures of chemotherapy, targeted therapy, and immunotherapy have all been attributed to the PDAC microenvironment. In this review, we dissect the components of the microenvironment and explain how each cell type contributes to form a highly immunosuppressive, hypoxic, and desmoplastic cancer. New efforts in single-cell profiling will enable a better understanding of the composition of the microenvironment in primary and metastatic PDAC, as well as an understanding of how the microenvironment may respond to novel therapeutic approaches. PMID- 29189329 TI - Diagnosis and Detection of Pancreatic Cancer. AB - Computed tomography is the first-line imaging modality for suspected pancreatic cancer. Magnetic resonance cholangiopancreatography is a second-line modality for suspected pancreatic cancer and is usually reserved for equivocal cases. Both computed tomography and MR are highly sensitive in the detection of pancreatic cancer, with up to 96% and 93.5% sensitivity, respectively. Computed tomography is superior to MR in the assessment of tumor resectability, with accuracy rates of up to 86.8% and 78.9%, respectively. Close attention to secondary signs of pancreatic cancer, such as pancreatic duct dilatation, abrupt pancreatic duct caliber change, and parenchymal atrophy, are critical in the diagnosis of pancreatic cancer. Emerging techniques such as radiomics and molecular imaging have the potential of identifying malignant precursors and lead to earlier disease diagnosis. The results of these promising techniques need to be validated in larger clinical studies. PMID- 29189328 TI - Understanding Disease Biology and Informing the Management of Pancreas Cancer With Preclinical Model Systems. AB - Recent advances in cytotoxic therapies for pancreatic ductal adenocarcinoma (PDA) are overshadowed by stalled clinical progress of more targeted strategies, the vast majority of which have failed in clinical trials. Inability to translate preclinical promise into clinical efficacy derives, in part, from imperfect disease modeling and mismatches between preclinical and clinical study design and execution. Into these gaps fall our patients who enter the clinical trial landscape expectantly and bear the brunt of its inadequacies. If improving patient survival is paramount, then it must be acknowledged that the failure of a phase III trial represents a larger failure of all of the work that preceded it. Repeated failures suggest a need to reappraise the current preclinical-to clinical apparatus. Exceptional models of PDA are now available to researchers, and the first steps toward a new era of success can begin with improved selection and application of these systems. We discuss the key features of the major preclinical platforms for PDA and propose a paradigm for rigorous interrogation of prospective therapies. PMID- 29189330 TI - Clinical Management: Resectable Disease. AB - Despite the identification of more active systemic therapy combinations for pancreatic cancer, cures remain elusive and feasible only in patients with localized, operable disease. When examining outcome data from phase III adjuvant trials conducted during the past decade, the survival for patients with localized disease has improved, likely owing to a combination of factors including more active adjuvant therapy and improved surgical and perioperative care. Perhaps the greatest recent change in the care of patients with localized pancreatic cancer has been the extension of surgery to tumors previously thought to be inoperable because of involvement of major blood vessels. These so-called "borderline resectable pancreatic cancers" have now been objectively defined, and their management is being studied in randomized trials. This has been made feasible by the availability of more active systemic therapy combinations that are increasingly being used in the neoadjuvant setting. Given the increasing activity of systemic regimens, the challenges in delivering such therapy in the postoperative setting, and the numerous novel agents in late stages of clinical development, it is reasonable to hypothesize that the neoadjuvant setting may eventually become the standard of care for patients with resectable disease. PMID- 29189331 TI - Ablative Radiotherapy Doses for Locally Advanced: Pancreatic Cancer (LAPC). AB - Standard palliative doses of radiation for locally advanced unresectable pancreatic cancer have had minimal to no impact on survival. Randomized trials evaluating these palliative doses have not shown a significant survival benefit with the use of radiation as consolidation after chemotherapy. Results from nonrandomized studies of 3- to 5-fraction low-dose stereotactic radiation (SBRT) have likewise had a minimal impact, but with less toxicity and a shorter treatment time. Doses of SBRT have been reduced to half the level that is necessary (biological equivalent dose, BED of 53 Gy) to achieve tumor ablation in the treatment of other solid tumors (100 Gy BED) to protect the gastrointestinal (GI) tract. The survival benefit of these palliative options is modest. In contrast, ablative doses of radiation (100 Gy BED) can be delivered using the same SBRT technique in 15 to 25 fractions. In addition to precision tumor targeting and solutions for respiratory motion as with SBRT, the delivery of ablative doses takes advantage of heterogeneous dosing, increased fractionation, which allows higher doses to be given, as well as adaptive planning to address day-to-day GI tract motion in selected cases. These higher doses have resulted in encouraging long-term survival results in multiple studies. In this review, we discuss the critical concepts and components of techniques that can be used to deliver ablative radiotherapy doses for patients with pancreatic tumors: fractionation, intentional dose heterogeneity, respiratory gating, image guidance, and adaptive planning. PMID- 29189332 TI - Clinical Management: Metastatic Disease. AB - Most patients with pancreatic cancer either present with or eventually develop metastatic disease during the course of their illness. For such individuals, systemic therapy, namely, cytotoxic therapy, represents the mainstay of treatment and is administered with noncurative intent. Of the various chemotherapy options now available for treating metastatic pancreatic cancer, 2 combination regimens, FOLFIRINOX (infusional 5-fluorouracil, leucovorin, irinotecan, and oxaliplatin) and the doublet of gemcitabine and albumin-bound paclitaxel, have emerged as frontline standards of care, based on phase III studies demonstrating a significant survival benefit compared with single-agent gemcitabine. More patients are also now able to be sequenced through 2 or more lines of treatment, with newer regimens such as nanoliposomal irinotecan plus infusional 5 fluorouracil and leucovorin receiving US Food and Drug Administration approval specifically for use in this second-line setting. Selection of therapies remains primarily guided by clinical considerations, particularly performance status, as well as age, comorbid medical conditions, and organ and bone marrow function. In contrast, molecular predictors of efficacy and toxicity have not yet been validated in this disease context. Areas of novel therapeutic development include targeting the stromal microenvironment, exploring combinations of immunotherapeutic agents, and identifying molecular subsets of metastatic pancreatic cancer that may uniquely susceptible to specific strategies, such as hampering DNA damage repair. PMID- 29189333 TI - Symptom Management and Palliative Care in Pancreatic Cancer. AB - Evidence documents the benefits of palliative care to ameliorate the symptoms of pancreatic cancer as well as those from its treatment. Professional organizations now recommend palliative care for all patients with pancreatic cancer early in the course of illness and concurrently with active treatment. Scrupulous symptom management as well as sensitive communication and advance care planning allow oncologists to provide "primary palliative care" and to care well for patients with pancreatic cancer throughout the course of their illness. PMID- 29189334 TI - Considerations in the Care of Athletes With Attention Deficit Hyperactivity Disorder. AB - OBJECTIVES: Uncover literature pertaining to: (1) attention deficit hyperactivity disorder (ADHD) and how it impacts athletes; (2) ADHD medication effects; (3) regulations regarding ADHD medications; (4) approaches to conditions similar to, and occurring with, ADHD; and (5) use of stimulants. DATA SOURCES: MEDLINE, Embase, PsycINFO, Cochrane Database of Systematic Reviews, Ovid interface. MAIN RESULTS: ADHD can have many effects on athletes and sports participation. Exercise has positive benefits on ADHD behaviors and players' attitudes. Athletes with ADHD can have worsened ADHD symptoms after concussions. Attention deficit hyperactivity disorder is a modifier of return to play; baseline ADHD symptoms should be used to guide management. Management should include medications, behavioral/psychosocial therapy, and academic accommodations. Behavioral therapy combined with medication is superior to behavioral treatment alone. Sustained exercise as ADHD treatment should be considered mainstay in management. Sports can increase thermogenic effects of stimulants, heat injury, and cardiac arrhythmias. Increased aggressiveness, improved pain tolerance, and decreased sense of fatigue are some attributes of stimulants that are presumed to impart some advantage to athletes, but evidence is uncertain. Attention deficit hyperactivity disorder medications may lead to myocardial infarctions, cerebrovascular accidents, paranoid psychoses, seizures, insomnia, tremors, anxiety, hypertension, and death. CONCLUSIONS: Athletes' performance and quality of life can be negatively affected by ADHD. Risks exist for those who take ADHD medications. More research is needed on the implications ADHD may have in specific sports, and on possible advantages of medication use. Potential deleterious effects of these medications should be addressed. PMID- 29189335 TI - Outcomes of Anterior Cruciate Ligament Reconstruction in Obese and Overweight Patients: A Systematic Review. AB - OBJECTIVE: To evaluate the mechanism of injury, outcomes, and complications of anterior cruciate ligament (ACL) reconstruction in overweight and obese patients. DATA SOURCES: MEDLINE, EMBASE, and OVID electronic libraries were systematically searched from inception to December, 2017 for any eligible articles using a combination of the phrases "anterior cruciate ligament," "ACL," "overweight," "obese," and "BMI." RESULTS: Studies that evaluated patients with primary ACL reconstruction, classified patients as overweight or obese, and reported a minimum of 1-year follow-up data were included. Eight cohorts from 9 studies fulfilled the inclusion criteria. There were no significant differences for mechanism of injury, Lysholm scores, Knee injury and Osteoarthritis Outcome Scores values, or return to sports with a body mass index (BMI) above or below 25 kg/m. A significant difference was described in International Knee Documentation Committee (IKDC) scores when comparing obese patients (BMI >30 kg/m) to patients with BMI <25 kg/m (P <0.01). In patients with BMI >25 kg/m, the risk for arthritis was significantly higher but the risk for revision surgery or contralateral ACL tear was lower (P <0.05). There was no significant difference in complication rates (P = 0.77). CONCLUSION: Patient-reported outcome measures were similar for patients with BMI above and below 25 kg/m, but there is evidence that obese patients have lower IKDC scores. There is a consistent association between overweight status and developing arthritis among patients having an ACL reconstruction. Overweight and obese patients have a lower risk of revision ACL reconstruction and contralateral ACL tear. There is insufficient data to make any conclusions regarding mechanism of injury or complications. More research is needed to better understand what is the appropriate counsel and treatment for overweight or obese patients with ACL tears. PROSPERO REGISTRATION NUMBER: CRD42017055594. PMID- 29189336 TI - History of High Motion Sickness Susceptibility Predicts Vestibular Dysfunction Following Sport/Recreation-Related Concussion. AB - OBJECTIVE: To compare vestibular dysfunction at 1 to 10 and 11 to 20 days following sport/recreation-related concussion (SRC) in athletes with and without history of motion sickness susceptibility. Secondary aims of this study were to investigate differences in neurocognitive performance and affective symptoms in these groups. DESIGN: Cross-sectional. SETTING: Concussion Specialty Clinic. PARTICIPANTS: One hundred twenty-four adolescents and adults (82 males, 42 females) aged 14 to 26 (16.36 +/- 2.10) years, diagnosed with SRC in the past 10 (4.56 +/- 2.54) days; 47 participants composed the sample for quartile analyses. INDEPENDENT VARIABLE: Motion sickness susceptibility questionnaire short form score. MAIN OUTCOME MEASURES: Computerized neurocognitive test scores, vestibular/oculomotor screening scores (VOMS), and symptom factor scores from a standardized concussion symptom inventory. RESULTS: There was no association between history of motion sickness susceptibility and VOMS scores (above or below clinical cutoff) at 1 to 10 days after injury, although at 11 to 20 days after injury there was an association between high motion sickness susceptibility and symptoms above clinical cutoff on 5 of the 6 VOMS items (P values 0.01-0.04). The high motion sickness group had more affective symptoms on the symptom inventory than the no motion sickness group (P = 0.002) at 1 to 10 days after injury. Groups did not differ on computerized neurocognitive testing (P = 0.11). CONCLUSION: Athletes with a preexisting history of motion sensitivity may exhibit more prolonged vestibular dysfunction following SRC, and may experience more affective symptoms early in recovery. PMID- 29189337 TI - Postexercise Hypotension as a Predictor for Long-Term Training-Induced Blood Pressure Reduction: A Large-Scale Randomized Controlled Trial. AB - OBJECTIVE: To investigate the correlation between acute exercise effects and chronic training effects on blood pressure (BP). DESIGN: Randomized, controlled training study focusing on the optimization of preventive effects of physical training. SETTING: The study was performed in a university department. PARTICIPANTS: One hundred twenty-seven healthy, untrained subjects. INTERVENTION: Subjects were divided into 4 groups: interval endurance training (IET) (n = 26, 4 * 4 min at 95% maximal heart rate), continuous endurance training (CET) (n = 23, 45 minutes at 60% heart rate reserve), strength endurance training (SET) (n = 40, 8 machine-based exercises, each 2 x 15 repetitions at the 20 repetition maximum), and control (CON) (n = 38). In the 3 training groups, subjects trained 3 times a week for 6 months, the CON group was asked to retain their sedentary lifestyle. MAIN OUTCOME MEASURES: The acute exercise effect on BP was defined as the change of BP after an exhaustive stage test, compared with baseline. The chronic training effect on BP was determined as the change of resting BP after the 6 month training period. RESULTS: For CET, a significant correlation between acute and chronic effects on systolic (r = 0.66, P = 0.001) and diastolic (r = 0.66, P = 0.001) BP was observed. For SET, a significant correlation (r = 0.45, P = 0.007) was found only for diastolic BP. No significant correlations were found for IET. CONCLUSIONS: It can be assumed that postexercise hypotension is an easy to-use predictor for the efficacy of CET to reduce BP, and may be a valuable tool for physicians to individualize prescribed training schedules for patients to reduce cardiovascular risk. TRIAL REGISTRATION: www.clinicaltrials.gov; ID: NCT01263522. PMID- 29189338 TI - Impact of CrossFit-Related Spinal Injuries. AB - INTRODUCTION: Exercise-related injuries (ERIs) are a common cause of nonfatal emergency department and hospital visits. CrossFit is a high-intensity workout regimen whose popularity has grown rapidly. However, ERIs due to CrossFit remained under investigated. METHODS: All patients who presented to the main hospital at a major academic center complaining of an injury sustained performing CrossFit between June 2010 and June 2016 were identified. Injuries were classified by anatomical location (eg, knee, spine). For patients with spinal injuries, data were collected including age, sex, body mass index (BMI), CrossFit experience level, symptom duration, type of symptoms, type of clinic presentation, cause of injury, objective neurological examination findings, imaging type, number of clinic visits, and treatments prescribed. RESULTS: Four hundred ninety-eight patients with 523 CrossFit-related injuries were identified. Spine injuries were the most common injuries identified, accounting for 20.9%. Among spine injuries, the most common location of injury was the lumbar spine (83.1%). Average symptom duration was 6.4 months +/- 15.1, and radicular complaints were the most common symptom (53%). A total of 30 (32%) patients had positive findings on neurologic examination. Six patients (6.7%) required surgical intervention for treatment after failing an average of 9.66 months of conservative treatment. There was no difference in age, sex, BMI, or duration of symptoms of patients requiring surgery with those who did not. CONCLUSIONS: CrossFit is a popular, high-intensity style workout with the potential to injure its participants. Spine injuries were the most common type of injury observed and frequently required surgical intervention. PMID- 29189339 TI - A Prospective, Randomized, Controlled Trial Comparing Conservative Treatment With Trunk Stabilization Exercise to Standard Hip Muscle Exercise for Treating Femoroacetabular Impingement: A Pilot Study. AB - OBJECTIVE: To assess the efficacy of conservative management of women with femoroacetabular impingement (FAI) using trunk stabilization. DESIGN: Randomized controlled trial (level of evidence: I). SUBJECTS: Twenty FAI female patients who met the inclusion FAI criteria. METHODS: A prospective, randomized, controlled study was performed on 20 female patients with symptomatic FAI comprising 2 groups (10 hips in trunk stabilization exercise group vs 10 hips in control group). We evaluated hip range of motion, isometric muscle strength using a handheld dynamometer (MU-TasMF-01; Anima, Co), and patient-reported outcome measures, including modified Harris hip score, Vail hip score, and international hip outcome tool 12 (iHOT12) before and at 4 weeks and 8 weeks after the intervention. RESULTS: There was a significant improvement in the range of motion of hip flexion in the trunk training group detected as early as 4 weeks after the intervention compared with the control group (P < 0.05). Hip abductor strength significantly improved in the trunk training group at 4 weeks after the intervention, whereas it did not improve in the control group (P < 0.05). Vail hip score and iHOT12 were significantly increased at 8 weeks after the intervention in the trunk training group compared with the control group (iHOT12: 78.7 +/- 22.4 vs 53.0 +/- 22.3; P < 0.01, Vail hip score: 81.6 +/- 18.5 vs 61.1 +/- 11.6; P < 0.05). There was no significant difference in the modified Harris hip score between both the groups at 4 and 8 weeks after the intervention. CONCLUSIONS: The addition of trunk stabilization exercise to a typical hip rehabilitation protocol improves short-term clinical outcomes and may augment nonoperative and postoperative rehabilitation.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial License 4.0 (CCBY-NC), where it is permissible to download, share, remix, transform, and buildup the work provided it is properly cited.

AB - OBJECTIVE: To determine whether decreased sleep duration postconcussion influences days to asymptomatic and assessment of performance throughout recovery. DESIGN: Prospective. SETTING: Institutional Clinical Research Laboratory. PATIENTS: Four hundred twenty-three collegiate athletes were diagnosed with concussion. INTERVENTIONS: Multidimensional concussion assessment battery was conducted at baseline, within 24 to 48 hours, daily [2-4 days postinjury (PI); symptoms only], once asymptomatic, and after return-to-play. The battery included the following: 22-item symptom checklist, Standardized Assessment of Concussion (SAC), Balance Error Scoring System (BESS), and computerized neurocognitive test [Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT)]. MAIN OUTCOME MEASURES: We subtracted baseline sleep duration from 24 to 48 hours postconcussion sleep duration and categorized athletes into the following groups: shorter sleep (<=-1 hour), no change (>-1 hour, <+1 hour), and longer sleep (>=+1 hour). A 1-way analysis of variance (ANOVA) was conducted to compare days to asymptomatic and separate mixed-model ANOVAs to compare total symptom scores, SAC total scores, BESS total error scores, and ImPACT composite scores between sleep categories across time points (alpha = 0.05). RESULTS: Sleep groups did not differ in days to asymptomatic. The shorter sleep group had greater symptom severity than no sleep change and longer sleep groups at 24 to 48 hours (shorter: 39.1 +/- 20.7; no change: 25.1 +/- 18.4, P = 0.007; longer: 25.7 +/- 21.8, P = 0.004), and at 2 to 4 days PI (shorter: 21.8 +/- 21.8; no change: 10.5 +/- 10.8, P = 0.013; longer: 11.9 +/- 14.2, P = 0.007), but did not differ at other time points (ie, asymptomatic and return-to play). Participants with shorter sleep exhibited slower ImPACT reaction times at 24 to 48 hours (shorter: 0.68 +/- 0.14; no change: 0.61 +/- 0.09, P = 0.016; and longer: 0.62 +/- 0.12, P = 0.028) and asymptomatic time points (shorter: 0.62 +/- 0.11; no change: 0.56 +/- 0.05; P = 0.015). CONCLUSION: Postinjury sleep declines may be associated with symptom severity and worsened reaction time during initial stages of recovery or may be the result of the concussion itself. Clinicians should be aware of alterations in sleep duration and manage appropriately to mitigate initial symptom burden postconcussion. PMID- 29189341 TI - Normative Data Set of SWAY Balance Mobile Assessment in Pediatric Athletes. AB - OBJECTIVE: To examine and describe normative values for an objective, mobile measure of postural stability commonly used in concussion assessments, SWAY Balance (SWAY Medical, Tulsa, Oklahoma). DESIGN: Retrospective analysis of baseline balance assessments in a healthy pediatric population. SETTING: Baseline assessments completed by certified athletic trainers at an outpatient concussion center or sports medicine offices in Philadelphia, PA and surrounding suburban Pennsylvania and New Jersey or during an athletic trainer's baseline assessment of collegiate athletes at a National Collegiate Athletic Association (NCAA) Division-II University in Fort Lauderdale, FL. PARTICIPANTS: Test results of a sample of 466 athletes aged 5 to 18 years were included. INTERVENTIONS: The SWAY Balance test was administered using a mobile device on all participants as part of a standard preseason, baseline evaluation, following the standard evaluation protocol. MAIN OUTCOME MEASURES: Baseline SWAY Balance mobile assessment balance and reaction time scores, age and sex effects, were examined. RESULTS: Normative scores are described, with results stratified into 4 age groups (5-9, 10-12, 13 17, and 18 years old). Balance scores, overall and within each individual stance score, improved with the age of the participants. Sex effects on balance were only seen in single-leg stances, with females outperforming males. Reaction time was found to be faster in males and improved with age, peaking at 13 to 17 years old and slowing in 18-year-olds. CONCLUSIONS: Normative, age-specific SWAY Balance test results provided are of clinical use as references in the concussion assessments of pediatric athletes. PMID- 29189342 TI - The Diagnostic Accuracy of Ultrasound in Detecting Distal Radius Fractures in a Pediatric Population. AB - OBJECTIVE: Sports ultrasound (US) is becoming popular in diagnosing musculoskeletal injuries. This study, also called the Pediatric Distal Radius Ultrasound Study (PeDRUS), compared the diagnostic accuracy of sports US with plain radiographs in possible distal radius buckle fractures in pediatric population. METHODS: In this prospective observational study, patients (2-15 years) presenting to an outpatient orthopedic injury clinic with distal forearm injuries without deformity were recruited. Bedside ultrasonography was performed and interpreted by the investigators as positive or negative for fracture. Plain radiographs were then performed and interpreted by the same investigator. The radiographs were considered the definitive imaging study for this investigation. RESULTS: Fifty-one patients were included with a mean age of 9.9 years. Fractures were diagnosed on both US and plain radiographs in 34 patients. Fractures were ruled out on both US and plain radiographs in 16 patients. There was only one case in which the US was interpreted differently than radiograph. For fractures of the distal radius in this population, the sensitivity was 97.1% [95% confidence interval (CI) = 89.2-97.1] and the specificity was 100% (95% CI = 82.5 100). The positive predictive value was 100% (95% CI = 91.8-100), whereas the negative predictive value was 94.1% (95% CI = 77.7-94.1). The positive likelihood ratio was infinite, suggesting utility in confirming a fracture. The negative likelihood ratio was 0.03 (95% CI = 0.03-0.13), suggesting that US has value in ruling out a fracture. CONCLUSIONS: Our study suggests that diagnostic sports US is sensitive and specific for detecting distal radius fractures in pediatric patients with nondeformed forearm injuries, demonstrating that US is an acceptable alternative to plain radiographs for evaluating fractures in a pediatric population. PMID- 29189344 TI - Accuracy of Invasive and Noninvasive Parameters for Diagnosing Ventilatory Overassistance During Pressure Support Ventilation. AB - OBJECTIVE: Evaluate the accuracy of criteria for diagnosing pressure overassistance during pressure support ventilation. DESIGN: Prospective clinical study. SETTING: Medical-surgical ICU. PATIENTS: Adults under mechanical ventilation for 48 hours or more using pressure support ventilation and without any sedative for 6 hours or more. Overassistance was defined as the occurrence of work of breathing less than 0.3 J/L or 10% or more of ineffective inspiratory effort. Two alternative overassistance definitions were based on the occurrence of inspiratory esophageal pressure-time product of less than 50 cm H2O s/min or esophageal occlusion pressure of less than 1.5 cm H2O. INTERVENTIONS: The pressure support was set to 20 cm H2O and decreased in 3-cm H2O steps down to 2 cm H2O. MEASUREMENTS AND MAIN RESULTS: The following parameters were evaluated to diagnose overassistance: respiratory rate, tidal volume, minute ventilation, peripheral arterial oxygen saturation, rapid shallow breathing index, heart rate, mean arterial pressure, change in esophageal pressure during inspiration, and esophageal and airway occlusion pressure. In all definitions, the respiratory rate had the greatest accuracy for diagnosing overassistance (receiver operating characteristic area = 0.92; 0.91 and 0.76 for work of breathing, pressure-time product and esophageal occlusion pressure in definition, respectively) and always with a cutoff of 17 incursions per minute. In all definitions, a respiratory rate of less than or equal to 12 confirmed overassistance (100% specificity), whereas a respiratory rate of greater than or equal to 30 excluded overassistance (100% sensitivity). CONCLUSION: A respiratory rate of 17 breaths/min is the parameter with the greatest accuracy for diagnosing overassistance. Respiratory rates of less than or equal to 12 or greater than or equal to 30 are useful clinical references to confirm or exclude pressure support overassistance. PMID- 29189343 TI - Kinetics of Urinary Cell Cycle Arrest Markers for Acute Kidney Injury Following Exposure to Potential Renal Insults. AB - OBJECTIVES: Urinary tissue inhibitor of metalloproteinase-2 and insulin-like growth factor binding protein 7 predict the development of acute kidney injury following renal insults of varied aetiology. To aid clinical interpretation, we describe the kinetics of biomarker elevations around an exposure. DESIGN: In an ancillary analysis of the multicenter SAPPHIRE study, we examined the kinetics of the urinary [tissue inhibitor of metalloproteinase-2]*[insulin-like growth factor binding protein 7] in association with exposure to common renal insults (major surgery, IV radiocontrast, vancomycin, nonsteroidal anti-inflammatory drugs, and piperacillin/tazobactam). SETTING: Thirty-five sites in North America and Europe between September 2010 and June 2012. PATIENTS: Seven hundred twenty-three critically ill adult patients admitted to the ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We compared the urinary [tissue metalloproteinase 2]*[insulin growth factor binding protein 7] kinetics from the day prior to exposure up to 5 days after exposure in patients developing acute kidney injury stage 2-3, stage 1, or no acute kidney injury by Kidney Disease Improving Global Outcome criteria. Among the 723 patients, 679 (94%) had at least one, 70% had more than one, and 35% had three or more exposures to a known renal insult. There was a significant association between cumulative number of exposures up to study day 3 and risk of acute kidney injury (p = 0.02) but no association between the specific type of exposure and acute kidney injury (p = 0.22). With the exception of radiocontrast, patients who developed acute kidney injury stage 2-3 after one of the five exposures, had a clear rise and fall of urinary [tissue inhibitor of metalloproteinase-2]*[insulin-like growth factor binding protein 7] from the day of exposure to 24-48 hours later. In patients without acute kidney injury, there was no significant elevation in urinary [tissue inhibitor of metalloproteinase 2]*[insulin-like growth factor binding protein 7]. CONCLUSIONS: Exposure to potential renal insults is common. In patients developing acute kidney injury stage 2-3, the kinetics of urinary [tissue inhibitor of metalloproteinase 2]*[insulin-like growth factor binding protein 7] matched the exposure except in the case of radiocontrast. PMID- 29189345 TI - Initial Antifungal Strategy Reduces Mortality in Critically Ill Patients With Candidemia: A Propensity Score-Adjusted Analysis of a Multicenter Study. AB - OBJECTIVE: The objective of this study was to evaluate the impact of the empirical therapy with fluconazole or an echinocandin on 30- and 90-day mortality in critically ill patients with candidemia. The outcome of patients in whom the empirical echinocandin was deescalated to fluconazole was also assessed. DESIGN: Retrospective, observational multicenter study. SETTING: Medical and surgical ICUs in nine Spanish hospitals. PATIENTS: Adult patients (>= 18 yr) with an episode of Candida bloodstream infection during ICU admission from January 2011 to April 2016. INTERVENTIONS: Patient characteristics, infection-related variables, therapeutic interventions, and metastatic complications were reviewed. A propensity score-adjusted multivariable analysis was performed to identify the risk factors significantly associated with 30-day and 90-day mortality. MEASUREMENTS AND MAIN RESULTS: A total of 294 patients were diagnosed of candidemia in the participant ICUs. Sixty patients were excluded (other antifungals in the primary therapy or the patient died without empirical antifungal therapy). The study group comprised 115 patients who received fluconazole (30-day mortality, 37.4%) and 119 patients treated empirically with an echinocandin (30-day mortality, 31.9%). The use of an echinocandin in the empirical therapy was a protective factor for 30-day (odds ratio, 0.32; 95% CI, 0.16-0.66; p = 0.002) and 90-day mortality (odds ratio, 0.50; 95% CI, 0.27-0.93; p = 0.014) in the propensity score- adjusted multivariable analysis. Deescalation of the empirical echinocandin to fluconazole was not associated with a higher mortality or the occurrence of long-term complications. CONCLUSIONS: Empirical use of an echinocandin in critically ill patients with documented candidemia reduces mortality at 30 and 90 days significantly. Deescalation of the empirical echinocandin to fluconazole is safe and effective in fluconazole-susceptible infections. PMID- 29189346 TI - Impact of Quality Bundle Enforcement by a Critical Care Pharmacist on Patient Outcome and Costs. AB - OBJECTIVES: Surgical and medical ICU patients are at high risk of mortality and provide a significant cost to the healthcare system. The aim of this study is to describe the effect of pharmacist-led interventions on drug therapy and clinical strategies on ICU patient outcome and hospital costs. DESIGN: Before and after study in two French ICUs (16 and 10 beds). PATIENTS: ICU patients. INTERVENTION: From January 1, 2013, to June 30, 2015, a pharmacist observation period was compared with an intervention period in which a critical care pharmacist provided recommendations to clinicians regarding sedative drugs and doses, choice of mechanical ventilation mode and related settings, antimicrobial de-escalation, and central venous and urinary catheters removal. Differences in ICU and hospital length of stay, duration of mechanical ventilation, mortality rate, and hospital costs per patient were quantified between groups with patients matched for severity of illness (Simplified Acute Physiology Score II) at admission. MEASUREMENTS AND MAIN RESULTS: From the 1,519 and 1,268 admitted patients during the observation and intervention periods, respectively, 1,164 patients were evaluable in both groups after matching for Simplified Acute Physiology Score II score. The intervention period was associated with mean (95% CI) reductions in patient hospital length of stay (3.7 d [5.2-2.3 d]; p < 0.001), ICU length of stay (1.4 d [2.3-0.5 d]; p < 0.005), duration of mechanical ventilation (1.2 d [2.1-0.3 d]; p < 0.01), and hospital costs per stay (2,560 euros [3,728-1,392 euros]; p < 0.001). The overall cost savings were 10,840 euros (10,727-10,952 euros) per month, mostly due to reduced consumption of sedatives and antimicrobials. No impact on mortality rate was identified. CONCLUSIONS: Critical care pharmacist-led interventions were associated with decreases in ICU and hospital length of stays and ICU drug costs. PMID- 29189347 TI - The Glucagon-Like Peptide-1 Analog Exenatide Increases Blood Glucose Clearance, Lactate Clearance, and Heart Rate in Comatose Patients After Out-of-Hospital Cardiac Arrest. AB - OBJECTIVES: To investigate the effects of the glucagon-like peptide-1 analog exenatide on blood glucose, lactate clearance, and hemodynamic variables in comatose, resuscitated out-of-hospital cardiac arrest patients. DESIGN: Predefined post hoc analyzes from a double-blind, randomized clinical trial. SETTING: The ICU of a tertiary heart center. PATIENTS: Consecutive sample of adult, comatose patients undergoing targeted temperature management after out-of hospital cardiac arrest from a presumed cardiac cause, irrespective of the initial cardiac rhythm. INTERVENTIONS: Patients were randomized 1:1 to receive 6 hours and 15 minutes of infusion of either 17.4 MUg of the glucagon-like peptide 1 analog exenatide (Byetta; Lilly) or placebo within 4 hours from sustained return of spontaneous circulation. The effects of exenatide were examined on the following prespecified covariates within the first 6 hours from study drug initiation: lactate level, blood glucose level, heart rate, mean arterial pressure, and combined dosage of norepinephrine and dopamine. MEASUREMENTS AND MAIN RESULTS: The population consisted of 106 patients receiving either exenatide or placebo. During the first 6 hours from study drug initiation, the levels of blood glucose and lactate decreased 17% (95% CI, 8.9-25%; p = 0.0004) and 21% (95% CI, 6.0-33%; p = 0.02) faster in patients receiving exenatide versus placebo, respectively. Exenatide increased heart rate by approximately 10 beats per minute compared to placebo (p < 0.0001). There was no effect of exenatide on other hemodynamic variables. CONCLUSIONS: In comatose out-of-hospital cardiac arrest patients, infusion with exenatide lowered blood glucose and resulted in increased clearance of lactate as well as increased heart rate. The clinical importance of these physiologic effects remains to be investigated. PMID- 29189349 TI - Role of epigenetics and DNA-damage in asthma. AB - PURPOSE OF REVIEW: Although asthma is a common disease worldwide, its pathogenesis remains to be fully elucidated. There is increasing evidence of the interaction between epigenetics, DNA-damage, and environmental allergens in the development of asthma. In this review, we will focus on the role of epigenetics and DNA-damage in asthma. RECENT FINDINGS: There is growing evidence of environmental allergens, particularly house dust mite, stimulating oxidative DNA damage in airway epithelial cells. The repair of this DNA damage has been implicated in the secretion of Th2 cytokines and the induction of allergic inflammation. SUMMARY: Studies of the role of epigenetics, DNA-damage, and environmental allergens have begun to reveal the their complex interactions and their roles in the development of asthma. Further study in these areas may lead to novel prevention and treatment approaches. PMID- 29189348 TI - Should Transfusion Trigger Thresholds Differ for Critical Care Versus Perioperative Patients? A Meta-Analysis of Randomized Trials. AB - OBJECTIVE: To address the significant uncertainty as to whether transfusion thresholds for critical care versus surgical patients should differ. DESIGN: Meta analysis of randomized controlled trials. SETTING: Medline, EMBASE, and Cochrane Library searches were performed up to 15 June 2016. PATIENTS: Trials had to enroll adult surgical or critically ill patients for inclusion. INTERVENTIONS: Studies had to compare a liberal versus restrictive threshold for the transfusion of allogeneic packed RBCs. MEASUREMENTS AND MAIN RESULTS: The primary outcome was 30-day all-cause mortality, sub-grouped by surgical and critical care patients. Secondary outcomes included myocardial infarction, stroke, renal failure, allogeneic blood exposure, and length of stay. Odds ratios and weighted mean differences were calculated using random effects meta-analysis. To assess whether subgroups were significantly different, tests for subgroup interaction were used. Subgroup analysis by trials enrolling critically ill versus surgical patients was performed. Twenty-seven randomized controlled trials (10,797 patients) were included. In critical care patients, restrictive transfusion resulted in significantly reduced 30-day mortality compared with liberal transfusion (odds ratio, 0.82; 95% CI, 0.70-0.97). In surgical patients, a restrictive transfusion strategy led to the opposite direction of effect for mortality (odds ratio, 1.31; 95% CI, 0.94-1.82). The subgroup interaction test was significant (p = 0.04), suggesting that the effect of restrictive transfusion on mortality is statistically different for critical care (decreased risk) versus surgical patients (potentially increased risk or no difference). Regarding secondary outcomes, for critically ill patients, a restrictive strategy resulted in reduced risk of stroke/transient ischemic attack, packed RBC exposure, transfusion reactions, and hospital length of stay. In surgical patients, restrictive transfusion resulted in reduced packed RBC exposure. CONCLUSIONS: The safety of restrictive transfusion strategies likely differs for critically ill patients versus perioperative patients. Further trials investigating transfusion strategies in the perioperative setting are necessary. PMID- 29189350 TI - Asthma: personalized and precision medicine. AB - PURPOSE OF REVIEW: In this review, we herein describe the progress in management of severe asthma, evolving from a 'blockbuster approach' to a more personalized approach targeted to the utilization of endotype-driven therapies. RECENT FINDINGS: Severe asthma characterization in phenotypes and endotypes, by means of specific biomarkers, have led to the dichotomization of the concepts of 'personalized medicine' and 'precision medicine', which are often used as synonyms, but actually have conceptual differences in meaning. The recent contribute of the omic sciences (i.e. proteomics, transcriptomics, metabolomics, genomics, ...) has brought this initially theoretic evolution into a more concrete level. SUMMARY: This step-by-step transition would bring to a better approach to severe asthmatic patients as the personalization of their therapeutic strategy would bring to a better patient selection, a more precise endotype driven treatment, and hopefully to better results in terms of reduction of exacerbation rates, symptoms, pulmonary function and quality of life. PMID- 29189351 TI - Lung ultrasound in diagnosing pneumonia in the emergency department: a systematic review and meta-analysis. AB - Community-acquired pneumonia (CAP) is one of the most widespread and severe infectious diseases worldwide. In the emergency department (ED), there is still a need for a rapid and accurate tool that can diagnose CAP. Lung ultrasound (LUS) is a recent tool that is increasingly being for this purpose. So far, the LUS has been evaluated on a wide range of patients, but not yet on the specific population in the ED through a meta-analysis. Our aim was to assess the accuracy of the LUS in diagnosing CAP in this setting through a systematic review and a meta-analysis. A systematic research of literature was carried out for all published studies comparing the diagnostic accuracy of the LUS against chest radiography or computerized tomography scan in patients older than 18 years of age with clinical criteria for CAP assessed in the ED. We extracted the descriptive and quantitative data from eligible studies, and calculated the pooled sensitivity, specificity, and diagnostic odds ratio. We defined the summary receiver operating characteristic curve. Our initial search strategy yielded 10 377 studies, of which 17 (0.2%) were eligible. These studies provided a combined sample size of 5108 participants. The general risk of bias of the considered studies was quite low, but some concerns were highlighted. The diagnostic odds ratio was around 181 (I: 27%). The pooled area under the curve, sensitivity, and specificity were, respectively, 97, 92, and 93%. The LUS was found to be an accurate tool in diagnosing CAP in adult patients in the ED. More methodologically rigorous trials are needed. PMID- 29189352 TI - Metagenomics in pediatrics: using a shotgun approach to diagnose infections. AB - PURPOSE OF REVIEW: With the advent of novel massively parallel sequencing technologies and bioinformatic processing capabilities, clinical applications of metagenomic studies are rapidly being integrated into medicine. Through this paper, we hope to introduce this powerful new tool to clinicians caring for children. RECENT FINDINGS: Very few studies have looked at metagenomic applications in children. The ability to perform these types of massive sequencing projects was not possible as little as 7 years ago. SUMMARY: Metagenomics is defined as the study of all genetic material within a given sample. Novel sequencing and analysis approaches allow for unbiased assays to identify pathogens missed by targeted sequencing and culture methods. Although not widely available yet, metagenomic studies have been used to diagnose pediatric infections, identify resistance genes in clinical samples, and characterize outbreaks. Although cost and turnaround time have limited its application in clinical laboratories to date, novel platforms and increasing comfort with these techniques continue to push diagnostic metagenomics into clinical pediatric medicine. Much work in this field is yet to be done. That being said, we feel that pediatric clinicians will be using metagenomic techniques in the care of children with increasing frequency in the near future. PMID- 29189353 TI - Pediatric palliative oncology: the state of the science and art of caring for children with cancer. AB - PURPOSE OF REVIEW: Pediatric palliative oncology (PPO) is an emerging field that integrates the principles of palliative care early into the illness trajectory of children with cancer. PPO providers work with interdisciplinary clinicians to provide optimal medical and psychosocial care to children with cancer and their families. Ongoing advances in the field of pediatric oncology, including new treatment options for progressive cancers, necessitate the early integration of palliative care tenets including holistic care, high-quality communication, and assessment and management of refractory symptoms. RECENT FINDINGS: Research in this emerging field has expanded dramatically over the past several years. This review will focus on advancements within several key areas of the field, specifically regarding investigation of the communication needs and preferences of patients and families, exploration of educational initiatives and interventions to teach PPO principles to clinicians, study of patient-reported and parent-reported tools to better assess and manage refractory symptoms, and development of novel models to integrate palliative care within pediatric oncology. SUMMARY: Research findings in the field of PPO, concurrent with advances in the treatment of pediatric cancer, may help improve survival and quality of life for children with cancer. PMID- 29189354 TI - Probiotics for prevention of Clostridium difficile infection. AB - PURPOSE OF REVIEW: Probiotics may prevent Clostridium difficile infection (CDI), a leading healthcare-associated infection in the United States. However, prior studies were limited by heterogeneity in products and patient populations. Recent clinical evidence and new approaches to probiotic development are reviewed. RECENT FINDINGS: Probiotic use may reduce incident CDI in high-risk populations by as much as 50%, though prior clinical trials have yielded conflicting results. Combining probiotics with prebiotics improves growth and engraftment in the host. Bacillus clausii and Lactobacillus reuteri secrete compounds that directly inhibit C. difficile. Organisms that produce secondary bile acids, such as Clostridium scindens, enhance C. difficile colonization resistance. Nontoxigenic C. difficile, which provides nutritional niche competition, may prevent CDI. Refinements to fecal microbiota transplantation (FMT) blur the line between probiotics and FMT. These include a quality-controlled stool product (RBX2660), purified Firmicutes spores (SER-109) and sterile fecal filtrate. Bacteriophages may treat CDI but have unknown safety and efficacy in humans. SUMMARY: There have been a number of advances in probiotics and our understanding of their role in prevention of CDI, but a number of important safety and efficacy questions remain. An improved understanding of the native microbiota structure and function will allow for continued development of rationally designed probiotic therapy to provide enhanced protection against CDI.

PMID- 29189365 TI - Using Integrative Medicine in Pain Management: An Evaluation of Current Evidence. AB - Complementary medicine therapies are frequently used to treat pain conditions such as headaches and neck, back, and joint pain. Chronic pain, described as pain lasting longer than 3-6 months, can be a debilitating condition that has a significant socioeconomic impact. Pharmacologic approaches are often used for alleviating chronic pain, but recently there has been a reluctance to prescribe opioids for chronic noncancer pain because of concerns about tolerance, dependence, and addiction. As a result, there has been increased interest in integrative medicine strategies to help manage pain and to reduce reliance on prescription opioids to manage pain. This article offers a brief critical review of integrative medical therapies used to treat chronic pain, including nutritional supplements, yoga, relaxation, tai chi, massage, spinal manipulation, and acupuncture. The goal of this article is to identify those treatments that show evidence of efficacy and to identify gaps in the literature where additional studies and controlled trials are needed. An electronic search of the databases of PubMed, The Cochrane Library, EMBASE, PsycINFO, and Science Citation Index Expanded was conducted. Overall, weak positive evidence was found for yoga, relaxation, tai chi, massage, and manipulation. Strong evidence for acupuncture as a complementary treatment for chronic pain that has been shown to decrease the usage of opioids was found. Few studies were found in which integrative medicine approaches were used to address opioid misuse and abuse among chronic pain patients. Additional controlled trials to address the use of integrative medicine approaches in pain management are needed. PMID- 29189366 TI - Role of Urine Drug Testing in the Current Opioid Epidemic. AB - While the evidence for urine drug testing for patients on chronic opioid therapy is weak, the guidelines created by numerous medical societies and state and federal regulatory agencies recommend that it be included as one of the tools used to monitor patients for compliance with chronic opioid therapy. To get the most comprehensive results, clinicians should order both an immunoassay screen and confirmatory urine drug test. The immunoassay screen, which can be performed as an in-office point-of-care test or as a laboratory-based test, is a cheap and convenient study to order. Limitations of an immunoassay screen, however, include having a high threshold of detectability and only providing qualitative information about a select number of drug classes. Because of these restrictions, clinicians should understand that immunoassay screens have high false-positive and false-negative rates. Despite these limitations, though, the results can assist the clinician with making preliminary treatment decisions. In comparison, a confirmatory urine drug test, which can only be performed as a laboratory-based test, has a lower threshold of detectability and provides both qualitative and quantitative information. A urine drug test's greater degree of specificity allows for a relatively low false-negative and false-positive rate in contrast to an immunoassay screen. Like any other diagnostic test, an immunoassay screen and a confirmatory urine drug test both possess limitations. Clinicians must keep this in mind when interpreting an unexpected test result and consult with their laboratory when in doubt about the meaning of the test result to avoid making erroneous decisions that negatively impact both the patient and clinician. PMID- 29189367 TI - Oxycodone Ingestion Patterns in Acute Fracture Pain With Digital Pills. AB - BACKGROUND: Opioid analgesics are commonly prescribed on an as-needed (PRN) basis for acute painful conditions. Uncertainty of how patients actually take PRN opioids, coupled with a desire to completely cover pain, leads to variable and overly generous opioid prescribing practices, resulting in a surplus of opioids. This opioid surplus becomes a source for diversion and nonmedical opioid use. Understanding patterns of actual opioid ingestion after acute painful conditions can help clinicians counsel patients on safe opioid use, and allow timely recognition and intervention when escalating opioid self-dosing occurs, to prevent tolerance and addiction. METHODS: We used a novel oxycodone digital pill system (ingestible biosensor within a standard gelatin capsule combined with 5-mg oxycodone) that when ingested, is activated by the chloride ion gradient in the stomach thereby emitting a radiofrequency signal captured by a wearable reader. The reader relays ingestion data to a cloud-based server that displays ingestion events to the study team. We deployed the oxycodone digital pill among opioid naive individuals discharged from the emergency department with acute fracture pain. Participants were trained on digital pill operation and discharged with twenty-one 5-mg oxycodone digital pills. They were instructed to take digital pills PRN for pain on discharge. We conducted a brief interview 7 days after study enrollment, at which point participants returned the digital pill system. We identified oxycodone ingestion events in real time by data from the digital pill system and performed pill counts at the return visit to validate digital pill reporting of medication ingestion. RESULTS: In this study, 26 individuals were approached; 16 enrolled with 15 completing the study. Participants ingested a median of 6 (3-9.5) oxycodone digital pills over the course of 7 days, with 82% of the oxycodone dose ingested in the first 3 days. In individuals who required operative repair, 86% (N = 6) continued to ingest opioids at 1 week. There was substantial variability in ingestion patterns between individuals. CONCLUSIONS: The utilization patterns of individuals with acute fracture pain could be captured using a digital pill system and revealed a median opioid ingestion of 45 mg morphine equivalents for acute pain over 7 days. Seven participants ceased using opioids within 4 days after discharge from the emergency department, although operative repair was associated with longer use. This digital pill system was able to measure changes in and patterns of opioid self-dosing, which varied between patients. PMID- 29189369 TI - In Response. PMID- 29189368 TI - Opioid Prescribing for the Treatment of Acute Pain in Children on Hospital Discharge. AB - BACKGROUND: The epidemic of nonmedical use of prescription opioids has been fueled by the availability of legitimately prescribed unconsumed opioids. The aim of this study was to better understand the contribution of prescriptions written for pediatric patients to this problem by quantifying how much opioid is dispensed and consumed to manage pain after hospital discharge, and whether leftover opioid is appropriately disposed of. Our secondary aim was to explore the association of patient factors with opioid dispensing, consumption, and medication remaining on completion of therapy. METHODS: Using a scripted 10 minute interview, parents of 343 pediatric inpatients (98% postoperative) treated at a university children's hospital were questioned within 48 hours and 10 to 14 days after discharge to determine amount of opioid prescribed and consumed, duration of treatment, and disposition of unconsumed opioid. Multivariable linear regression was used to examine predictors of opioid prescribing, consumption, and doses remaining. RESULTS: Median number of opioid doses dispensed was 43 (interquartile range, 30-85 doses), and median duration of therapy was 4 days (interquartile range, 1-8 days). Children who underwent orthopedic or Nuss surgery consumed 25.42 (95% confidence interval, 19.16-31.68) more doses than those who underwent other types of surgery (P < .001), and number of doses consumed was positively associated with higher discharge pain scores (P = .032). Overall, 58% (95% confidence interval, 54%-63%) of doses dispensed were not consumed, and the strongest predictor of number of doses remaining was doses dispensed (P < .001). Nineteen percent of families were informed how to dispose of leftover opioid, but only 4% (8 of 211) did so. CONCLUSIONS: Pediatric providers frequently prescribed more opioid than needed to treat pain. This unconsumed opioid may contribute to the epidemic of nonmedical use of prescription opioids. Our findings underscore the need for further research to develop evidence-based opioid prescribing guidelines for physicians treating acute pain in children. PMID- 29189370 TI - In Response. PMID- 29189371 TI - Ectopic Adrenocorticotropic Hormone-Secreting Pituitary Adenoma Localized by 18F Choline PET/CT. AB - The criterion standard of treatment of an adrenocorticotropic hormone (ACTH) secreting pituitary adenoma is complete surgical excision. However, ectopic location of these adenomas is an extremely rare condition, which may affect the diagnosis and treatment success. We report a case of a 49-year-old man who was referred to our institution with persistent hypercortisolemia after an unsuccessful attempt of surgical resection. F-choline PET/CT revealed increased radiopharmaceutical uptake in a nodule localized in the left maxillary sinus, which was proved at histology to be an ectopic ACTH-secreting pituitary adenoma staining positive for ACTH. Imaging with F-FDG PET/CT and Ga-DOTA-NOC PET/CT was not diagnostic. PMID- 29189372 TI - Multifunctional Assessment of Non-Small Cell Lung Cancer: Perfusion-Metabolic Correlation. AB - PURPOSE: The aim of this study was to investigate the relationship between whole tumor CT perfusion and FDG PET/CT parameters in non-small cell lung cancer (NSCLC). METHODS: Twenty-five patients with NSCLC were prospectively included. CT perfusion parameters calculated were blood flow (BF), blood volume (BV), mean transit time, and peak enhancement intensity. SUVmax, SUVpeak, SUVmean, metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were evaluated for PET/CT. Tumor diameter and volume were measured, and lesions were divided according to maximum axial diameter in more than 3 cm and 3 cm or less. The correlations between CT perfusion and PET/CT parameters were assessed in all tumors, as well as according to tumor diameter and volume. RESULTS: Lesion diameter and volume showed a negative correlation with BF and BV (r = -0.78, -0.78, -0.57, -0.48, respectively) and a positive correlation with mean transit time (r = 0.55, 0.65, respectively). The negative correlation between BF and lesion diameter and volume was confirmed in the subgroup of lesions of more than 3 cm (r = -0.68, -0.68, respectively). A positive correlation between SUVmax, SUVpeak, SUVmean, and lesion volume was observed (r = 0.50, 0.50, 0.46, respectively) and confirmed in lesions 3 cm or less (r = 0.81, 0.79, 0.78, respectively). Metabolic tumor volume and TLG showed a positive correlation with lesion diameter and volume in the overall population (r = 0.93, 0.87, 0.88, 0.90, respectively) and in lesions of more than 3 cm (r = 0.89, 0.84, 0.84, 0.79, respectively). Blood flow and BV showed a negative correlation with MTV and TLG (r = -0.77, -0.74, and -0.58, 0.48, respectively) in the overall population and with MTV in lesions of more than 3 cm (r = -0.69, -0.62, respectively). CONCLUSIONS: Perfusion and metabolic parameters seem to depend on tumor size. The bigger the tumor, the lower the BF and the BV and, conversely, the higher the SUVpeak, MTV, and TLG. This information would be useful in the clinical setting when diagnosing or treating NSCLC, especially with novel therapies and/or for radiation treatment modulation.

Malignant lymphoma was suspected because of mediastinal lymph nodes swelling on CT and soluble interleukin 2 receptor elevation. Symmetric F-FDG uptake in the tracheobronchial tree and bilateral auricles was observed on PET/CT. He was finally diagnosed as having relapsing polychondritis by auricular cartilage biopsy. F-FDG PET/CT may have crucial role in evaluating the extent of inflammation and deciding the biopsy site of relapsing polychondritis.

We present a case of focal autoimmune pancreatitis with abnormal FDG activity involving only the pancreatic tail on PET/CT in a 61-year-old man who was provisionally diagnosed as having pancreatic cancer based on the CT findings. The diagnosis of autoimmune pancreatitis was based on pathological examination and elevated serum immunoglobulin G4 level. Following the steroid therapy, the patient was gradually recovered. PMID- 29189378 TI - Simultaneous Brain and Lung Histiocytic Sarcoma Revealed on 18F-FDG PET/CT. AB - A 52-year-old man with intermittent head motor tics, aphasia and right upper extremity weakness had an F-FDG avid left front lobe brain lesion, and a left upper lobe lung lesion on PET/CT. The brain lesion was surgically resected, and was diagnosed pathologically as a histiocytic sarcoma (HS). The lung lesion was also a HS via bronchial biopsy. HS is rare and generally involves nodes as shown on PET/CT in a few case reports. The current case with simultaneous brain and lung HS lesions adds new imaging pattern information of the disease to the literature. PMID- 29189379 TI - Impact of Surgical Margin Width on Recurrence and Overall Survival Following R0 Hepatic Resection of Colorectal Metastases: A Systematic Review and Meta analysis. AB - OBJECTIVE: To examine the impact of surgical margin width on survival following R0 hepatic resection for colorectal metastases (CRLM). SUMMARY OF BACKGROUND DATA: Although negative resection margin is considered of paramount importance for the prognosis of patients with colorectal liver metastases, optimal resection margin width remains controversial. METHODS: Eligible studies examining the association between margin status after R0 hepatic resection for CRLM and survival, including overall survival (OS) and disease-free survival (DFS) were sought using the Medline, Cochrane, and EMBASE databases. Random-effects models were used for the calculation of pooled relative risks (RRs) with their 95% confidence intervals (95% CIs). RESULTS: Thirty-four studies were deemed eligible for inclusion representing a cohort of 11,147 hepatic resections. Wider resection margin (>1 vs <1 cm) was significantly associated with improved OS at 3 years (pooled RR = 0.86, 95% CI: 0.79-0.95), 5 years (pooled RR = 0.91, 95% CI: 0.85 0.97), and 10 years (pooled RR = 0.94, 95% CI: 0.88-1.00). Similarly, DFS was positively associated with >1 cm resection margin at 3, 5, and 10 years. Interestingly, >1 mm (vs <1 mm) resection margin was significantly associated with improved OS at all-time points. Meta-regression analyses did not reveal any significant modifying role of the study features under investigation, such as the administration of neoadjuvant/adjuvant therapy. CONCLUSIONS: Importantly, our findings suggest that while a >1 mm margin is associated with better prognosis than a submillimeter margin, achieving a margin >1 cm may result in even better oncologic outcomes and should be considered if possible.

PMID- 29189383 TI - Sinai Abbreviated Geriatric Evaluation: Development and Validation of a Practical Test. AB - OBJECTIVE: To develop and validate a simple geriatric screening tool that performs as well as more complex assessments BACKGROUND:: Many tools that predict treatment risk in older adults are impractical for routine clinical use. METHODS: We prospectively conducted comprehensive preoperative evaluations on 1025 patients age >=75 years who presented to Sinai Hospital of Baltimore for major elective surgery, then retrospectively reviewed patients' medical records for occurrence of postoperative outcomes. Using logistic regression modeling and receiver operating characteristic curve analysis we selected the best combination of simple tests, labeling this the Sinai Abbreviated Geriatric Evaluation (SAGE). The performance of the SAGE was then compared with 3 standard tools in its power to predict postoperative outcomes. RESULTS: The SAGE is a statistically significant predictor of postoperative outcomes. Each unit decrease in SAGE score was significantly associated with a 51% (95% CI 1.30-1.77) increase in odds of a complication, a 2-fold increase in odds of postoperative delirium (95% CI 1.65 2.66), a 27% increase in odds of length of hospital stay >2 days (95% CI 1.10 1.47), a 54% increase in odds of a hospital readmission within 30 days (95% CI 1.25-2.88), and a 38% increase in odds of an unanticipated discharge to higher level care (95% CI 1.18-1.61). We estimated the receiver operating characteristic curve area under the curve (AUC) for the SAGE of 0.69, 0.77, 0.73, 0.66, and 0.78 for the above outcomes, respectively. The SAGE performed as well in predicting postoperative outcomes as Fried's frailty phenotype, Charlson Comorbidity Index, and American Society of Anesthesiologists Physical Status Class (ASA). CONCLUSION: The SAGE performs as well as other geriatric evaluations that require equipment or memorization. PMID- 29189384 TI - The Evolution of Surgical Strategies for Pancreatic Neuroendocrine Tumors (Pan NENs): Time-trend and Outcome Analysis From 587 Consecutive Resections at a High volume Institution. AB - OBJECTIVE: The objective of the present analysis is 2-fold: first, to define the evolution of time trends on the surgical approach to pancreatic neuroendocrine neoplasms (Pan-NENs); second, to perform a complete analysis of the predictors of oncologic outcome. BACKGROUND: Reflecting their rarity and heterogeneity, Pan NENs represent a clinical dilemma. In particular, there is a scarcity of data regarding their long-term follow-up after surgical resection. METHODS: From the Institutional Pan-NEN database, 587 resected cases from 1990 to 2015 were extracted. The time span was arbitrarily divided into 3 discrete clusters enabling a balanced comparison between patient groups. Analyses for predictors of recurrence and survival were performed, together with conditional survival analyses. RESULTS: Among the 587 resected Pan-NENs, 75% were nonfunctioning tumors, and 5% were syndrome-associated tumors. The mean age was 54 years (+/-14 years), and 51% of the patients were female. The median tumor size was 20 mm (range 4 to 140), 62% were G1, 32% were G2, and 4% were G3 tumors. Time trends analysis revealed that the number of resected Pan-NENs constantly increased, while the size (from 25 to 20 mm) and G1 proportion (from 65% to 49%) decreased during the study period. After a mean follow-up of 75 months, recurrence analysis revealed that nonfunctioning tumors, tumor grade, N1 status, and vascular invasion were all independent predictors of recurrence. Regardless of size, G1 nonfunctioning tumors with no nodal involvement and vascular invasion had a negligible risk of recurrence at 5 years. CONCLUSIONS: Pan-NENs have been increasingly diagnosed and resected during the last 3 decades, revealing reliable predictors of outcome. Functioning and nodal status, tumor grade, and vascular invasion accurately predict survival and recurrence with resulting implications for patient follow-up. PMID- 29189385 TI - Portal Inflow Modulation by Somatostatin After Major Liver Resection: A Pilot Study. AB - : Major hepatectomy (MH) can lead to an increasing portal vein pressure (PVP) and to lesions of the hepatic parenchyma. Several reports have assessed the deleterious effect of a high posthepatectomy PVP on the postoperative course of MH. Thus, several surgical modalities of portal inflow modulation (PIM) have been described. As for pharmacological modalities, experimental studies showed a potential efficiency of Somatostatin to reduce PVP and flow. To our knowledge, no previous clinical reports of PIM using somatostatin are available. Herein, we report the results of PIM using somatostatin in 10 patients who underwent MH with post-hepatectomy PVP > 20 mmHg. Our results suggest Somatostatin could be considered as an efficient reversible PIM when PVP decrease is above 2.5 mmHg. PMID- 29189386 TI - Postoperative Voiding Dysfunction: The Preferred Method for Catheterization. AB - OBJECTIVES: Bladder drainage can be achieved by clean intermittent self catheterization (CISC), transurethral indwelling catheterization (TIC), or with a suprapubic tube (SPT). The primary objective of this study was to determine patient preference for catheter type in the management of potential voiding dysfunction after pelvic organ prolapse (POP) surgery. METHODS: Between 2012 and 2016, patients scheduled for POP surgery were recruited into the study. Before surgery, patients were informed of the potential for postoperative voiding dysfunction and the catheter choices were discussed. Each patient's choice was recorded along with baseline information, surgery performed, and perioperative details. After surgery, voiding dysfunction, length of catheter use, scores on a catheter satisfaction questionnaire, as well as uroflowmetry and urine culture testing were assessed. RESULTS: Of those recruited to the study (N = 150), 6.7% chose CISC, 7.3% chose TIC, and 86% chose SPT. Catheter satisfaction score 1 week after surgery was significantly better for SPT compared with CISC and TIC (P = 0.005). In addition, at week 1, 33% of CISC, 25% of TIC, and 13% of SPT had a PVR of more than 30% (P = 0.002) on uroflowmetry, and 33% of CISC, 50% of TIC, and 24% of SPT had a positive urine culture (P = 0.05). CONCLUSIONS: This study has shown that patients prefer SPT over CISC and TIC for management of voiding dysfunction after POP surgery. Use of SPT showed better satisfaction rates, better uroflowmetry results, and lower infection rates 1 week after surgery. Patient preference is an important factor in this decision and can help facilitate a clinical approach. PMID- 29189387 TI - Ex Vivo-expanded Natural Killer Cells Derived From Long-term Cryopreserved Cord Blood are Cytotoxic Against Primary Breast Cancer Cells. AB - With over 600,000 units of umbilical cord blood (CB) stored on a global scale, it is important to elucidate the therapeutic abilities of this cryopreserved reservoir. In the advancing field of natural killer (NK) cell cancer immunotherapy, CB has proven to be a promising and noninvasive source of therapeutic NK cells. Although studies have proven the clinical efficacy of using long-term cryopreserved CB in the context of hematopoietic stem cell transplantations, little is known about its use for the ex vivo expansion of effector immune cells. Therefore, our group sought to derive ex vivo-expanded NK cells from long-term cryopreserved CB, using an artificial antigen presenting cell-mediated expansion technique. We compared the expansion potential and antitumor effector function of CB-derived NK (CB-NK) cells expanded from fresh (n=4), short-term cryopreserved (<1-year old, n=5), and long-term cryopreserved (1-10-year old, n=5) CB. Here, we demonstrated it is possible to obtain an exponential amount of expanded CB-NK cells from long-term cryopreserved CB. Ex vivo-expanded CB-NK cells had an increased surface expression of activating markers and showed potent antitumor function by producing robust levels of proinflammatory cytokines, interferon-gamma, and tumor necrosis factor-alpha. Moreover, expanded CB-NK cells (n=3-5) demonstrated cytotoxicity towards primary breast cancer cells (n=2) derived from a triple-negative breast cancer and an estrogen receptor-positive/progesterone receptor-positive breast cancer patient. Long-term cryopreservation had no effect on the expansion potential or effector function of expanded CB-NK cells. Therefore, we propose that long-term cryopreserved CB remains clinically useful for the ex vivo expansion of therapeutic NK cells. PMID- 29189389 TI - Editorial: I Pledge. PMID- 29189388 TI - CD11c-targeted Delivery of DNA to Dendritic Cells Leads to cGAS- and STING dependent Maturation. AB - Immunotherapeutic activation of tumor-specific T cells has proven to be an interesting approach in anticancer treatment. Particularly, anti-CTLA-4 and anti PD-1/PD-L1 treatment looks promising, and conceivably, even better clinical results might be obtained if such treatment could be combined with boosting the existing tumor-specific T-cell response. One way to achieve this could be by increasing the level of maturation of dendritic cells locally and in the draining lymph nodes. When exposed to cancer cells, dendritic cells may spontaneously mature because of danger-associated molecular patterns derived from the tumor cells. Double-stranded DNA play a particularly important role in the activation of the dendritic cells, through engagement of intracellular DNA-sensors, and signaling through the adaptor protein STING. In the present study, we have investigated the maturational response of human monocyte-derived dendritic cells (moDC) and human monocytic THP-1 cells to targeted and untargeted DNA. We used an anti-CD11c antibody conjugated with double-stranded DNA to analyze the maturation status of human moDCs, as well as maturation using a cGAS KO and STING KO THP-1 cell maturation model. We found that dendritic cells can mature after exposure to cytoplasmic double-stranded DNA delivered through CD11c-mediated endocytosis. Moreover, we show that THP-1 cells matured using IL-4, GM-CSF, and ionomycin upregulate DC-maturation markers after CD11c-targeted delivery of double-stranded DNA. This upregulation is completely abrogated in cGAS KO and STING KO cells. PMID- 29189390 TI - Quality of Life of Implant-Supported Overdenture and Conventional Complete Denture in Restoring the Edentulous Mandible: A Systematic Review. AB - OBJECTIVE: The aim of this systematic review was to evaluate the oral health related quality of life (OHRQoL) associated with an implant-supported overdenture (IOD) compared with a conventional complete denture (CCD) in restoring the edentulous mandible. METHODS: A literature search was performed in the MEDLINE (through Ovid), PubMed, and Cochrane Library databases for articles published between 1990 and July 2016. The search was restricted to articles published in English. Two reviewers selected the articles based on the inclusion and exclusion criteria. Another 2 reviewers analyzed the data. RESULTS: From 108 articles that were obtained, 5 articles met the inclusion criteria. Four studies had a high risk of bias, and 1 study had an unclear risk of bias. There was a significant difference in Oral Health Impact Profile (OHIP) scores between pre- and post treatment within the groups and in posttreatment OHIP scores between IOD and CCD groups. CONCLUSION: Regarding the edentulous mandible, patients benefited more from the IOD with 2 implants, as determined by OHRQoL scores. Considering the differences between each domain of the Oral Health Impact Profile (OHIP) questionnaire and the lack of long-term performance, more random control trials with sufficient sample sizes need to be designed to investigate long-term performance after treatment. PMID- 29189391 TI - Blood biomarkers for early diagnosis of oesophageal cancer: a systematic review. AB - BACKGROUND: Oesophageal cancer prognosis remains poor owing to the inability to detect the disease at an early stage. Nontissue (serum, urinary or salivary) biomarkers potentially offer less invasive methods to aid early detection of oesophageal cancer. We aimed to systematically review studies assessing the relationship between nontissue biomarkers and subsequent development of oesophageal cancer. METHODS: Using terms for biomarkers and oesophageal cancer, Medline, EMBASE and Web of Science were systematically searched for longitudinal studies, published until April 2016, which assessed the association between nontissue biomarkers and subsequent oesophageal cancer risk. Random effects meta analyses were used to calculate pooled relative risk (RR) and 95% confidence intervals (CIs), where possible. RESULTS: A total of 39 studies were included. Lower serum pepsinogen I concentrations were associated with an increased risk of oesophageal squamous cell carcinoma (n=3 studies, pooled RR=2.20, 95% CI: 1.31 3.70). However, the association for the pepsinogen I : II ratio was not statistically significant (n=3 studies, pooled RR=2.22, 95% CI: 0.77-6.40), with a large degree of heterogeneity observed (I=68.0%). Higher serum glucose concentrations were associated with a modestly increased risk of total oesophageal cancer (n=3 studies, pooled RR=1.27, 95% CI: 1.02-1.57). No association was observed for total cholesterol and total oesophageal cancer risk (n=3 studies, pooled RR=0.95, 95% CI: 0.58-1.54). Very few studies have assessed other biomarkers for meta-analyses. CONCLUSION: Serum pepsinogen I concentrations could aid early detection of oesophageal squamous cell carcinoma. More prospective studies are needed to determine the use of other nontissue biomarkers in the early detection of oesophageal cancer. PMID- 29189392 TI - Validation of inflammation-based prognostic models in patients with hepatitis B associated hepatocellular carcinoma: a retrospective observational study. AB - BACKGROUND AND OBJECTIVE: The objective of this study was to investigate the prognostic significance of several inflammation-based models in hepatitis B associated hepatocellular carcinoma (HCC). PATIENTS AND METHODS: We retrospectively reviewed 470 cases of hepatitis B-associated HCC. Preoperative data were collected to calculate the inflammation-based markers, including systemic immune-inflammation index (neutrophil*platelets/lymphocyte), platelets to-lymphocyte ratio, and neutrophil-to-lymphocyte ratio (NLR). Overall survival and recurrence-free survival were estimated by the Kaplan-Meier method and Cox analysis. RESULTS: During a median follow-up time of 29 months, 34.0% (160/470) of patients died and 36.0% (169/470) experienced recurrence. Compared with patients with lower scores of inflammation models, patients in the higher group had larger tumor diameter and higher risk of vascular invasion (both P<0.05). Multivariate analysis revealed that age, tumor size, platelets-to-lymphocyte ratio, NLR, and systemic immune-inflammation index were the independent predictors for both overall survival and recurrence-free survival. Furthermore, the combination of tumor size and NLR showed a significantly better discrimination ability for survival (C-index=0.716, 95% confidence interval: 0.664-0.768) than both Barcelona Clinic Liver Cancer and Cancer of Liver Italian Program. CONCLUSION: The inflammation-based markers, in particular the combination of NLR with tumor size, are effective tools for assessing prognosis in hepatitis B-associated HCC. PMID- 29189393 TI - Acute pancreatitis in the elderly: a cause for increased concern? AB - BACKGROUND: Acute pancreatitis (AP) is an aggressive and potentially fatal clinical condition. Although all age groups are at risk, the elderly may be a group of special concern. We aimed at evaluating clinical outcomes of patients with elderly-onset AP. MATERIALS AND METHODS: Using a single-center retrospective database, treatment and follow-up records of 550 patients admitted with AP were reviewed. Outcomes included mortality, admission to the ICU, need for interventional procedures, nutritional support, and length of hospital and ICU stay. Elderly-onset AP was defined as an episode of AP occurring in patients older than 65 years. RESULTS: A total of 263 patients were classified as having elderly-onset AP. There was an association between older age and higher Ranson and the bedside index of severity in AP scores, translating into longer lengths of hospital stay, higher requirements for ICU admission, interventional procedures, organ failure, persistent organ failure, and overall mortality. In multivariate analysis, age was an independent predictor of mortality in AP. CONCLUSIONS: Age was strongly associated with a more severe course of AP. Early recognition and prompt action are essential to improve outcomes in this population. PMID- 29189394 TI - Ischemic stroke in liver cirrhosis: epidemiology, risk factors, and in-hospital outcomes. AB - BACKGROUND AND AIMS: Patients with cirrhosis are reportedly more prone to develop hemorrhagic stroke, thereby increasing the risk of death. However, the effect of ischemic stroke on liver diseases remains unclear. In addition, few studies have explored the risk factors for ischemic stroke in patients with liver cirrhosis. Our study aimed to explore the epidemiology, risk factors, and in-hospital outcomes of ischemic stroke in a large cohort of hospitalized patients with cirrhosis. PATIENTS AND METHODS: In this single-center observational study, we retrospectively reviewed the medical records of patients with liver cirrhosis admitted to our hospital from January 2011 to June 2014. A diagnosis of ischemic stroke was further identified. RESULTS: Of the 2444 patients with liver cirrhosis, 160 had ischemic stroke, including 128 patients with previous ischemic stroke and 32 patients with new-onset ischemic stroke during their hospitalizations. Compared with patients with cirrhosis without ischemic stroke, those with ischemic stroke were significantly older; had a significantly higher proportion of arterial hypertension and a significantly lower proportion of hepatitis B virus infection; had significantly higher white blood cell, platelet, blood urea nitrogen, and triglyceride levels; and had significantly lower alanine aminotransferase and aspartate aminotransferase levels and prothrombin time. The in-hospital mortality was significantly higher in patients with ischemic stroke than in those without [8.80% (14/160) vs. 3.2% (72/2284), P=0.001]. CONCLUSION: Ischemic stroke was often observed in patients with cirrhosis, and it significantly increased the in-hospital mortality. The association of inflammation, coagulation disorders, and viral hepatitis with development of ischemic stroke in liver cirrhosis should be further evaluated in prospective cohort studies. PMID- 29189395 TI - Augmented Quadruple-Phase Contrast Media Administration and Triphasic Scan Protocol Increases Image Quality at Reduced Radiation Dose During Computed Tomography Urography. AB - PURPOSE: The aim of this article was to investigate the opacification of the renal vasculature and the urogenital system during computed tomography urography by using a quadruple-phase contrast media in a triphasic scan protocol. MATERIALS AND METHODS: A total of 200 patients with possible urinary tract abnormalities were equally divided between 2 protocols. Protocol A used the conventional single bolus and quadruple-phase scan protocol (pre, arterial, venous, and delayed), retrospectively. Protocol B included a quadruple-phase contrast media injection with a triphasic scan protocol (pre, arterial and combined venous, and delayed), prospectively. Each protocol used 100 mL contrast and saline at a flow rate of 4.5 mL. Attenuation profiles and contrast-to-noise ratio of the renal arteries, veins, and urogenital tract were measured. Effective radiation dose calculation, data analysis by independent sample t test, receiver operating characteristic, and visual grading characteristic analyses were performed. RESULTS: In arterial circulation, only the inferior interlobular arteries in both protocols showed a statistical significance (P < 0.05). Venously, the inferior vena cava, proximal and distal renal veins demonstrated a significant opacification reduction in protocol B than in protocol A (P < 0.001). Protocol B showed a significantly higher mean contrast-to-noise ratio than protocol A (protocol B: 22.68 +/- 13.72; protocol A: 14.75 +/- 5.76; P < 0.001). Radiation dose was significantly reduced in protocol B (7.38 +/- 2.22 mSv) than in protocol A (12.28 +/- 2.72 mSv) (P < 0.001). Visual grading characteristic (P < 0.027) and receiver operating characteristic (P < 0.0001) analyses demonstrated a significant preference for protocol B. CONCLUSIONS: In computed tomography urography, augmented quadruple phase contrast media and triphasic scan protocol usage increases the image quality at a reduced radiation dose. PMID- 29189396 TI - Computed Tomography-Based Texture Analysis to Determine Human Papillomavirus Status of Oropharyngeal Squamous Cell Carcinoma. AB - OBJECTIVE: To determine whether machine learning can accurately classify human papillomavirus (HPV) status of oropharyngeal squamous cell carcinoma (OPSCC) using computed tomography (CT)-based texture analysis. METHODS: Texture analyses were retrospectively applied to regions of interest from OPSCC primary tumors on contrast-enhanced neck CT, and machine learning was used to create a model that classified HPV status with the highest accuracy. Results were compared against the blinded review of 2 neuroradiologists. RESULTS: The HPV-positive (n = 92) and -negative (n = 15) cohorts were well matched clinically. Neuroradiologist classification accuracies for HPV status (44.9%, 55.1%) were not significantly different (P = 0.13), and there was a lack of agreement between the 2 neuroradiologists (kappa = -0.145). The best machine learning model had an accuracy of 75.7%, which was greater than either neuroradiologist (P < 0.001, P = 0.002). CONCLUSIONS: Useful diagnostic information regarding HPV infection can be extracted from the CT appearance of OPSCC beyond what is apparent to the trained human eye. PMID- 29189397 TI - Patterns of Coronary Calcification and Their Impact on the Diagnostic Accuracy of Computed Tomography Coronary Angiography. AB - OBJECTIVE: Despite coronary calcifications being a major factor affecting the diagnostic accuracy of coronary computed tomography angiography (CTA), there is a lack of established criteria for categorizing calcifications. We aimed to evaluate patterns of coronary calcification based on quantitative radiodensity and size parameters to provide coronary calcium categories and assess their impact on the accuracy of coronary CTA. METHODS AND RESULTS: We analyzed length, maximum thickness, volume, mean density, and maximum density of coronary calcium and divided each of these parameters into tertiles. Subsequently, we summarized the tertiles for each individual calcification and divided them into 3 equal groups of: mild, moderate, and severe calcification. The accuracy of coronary CTA was defined as the difference between the measurements obtained on coronary CTA versus the reference of intravascular ultrasound (IVUS). We evaluated 252 coronary calcifications within 97 arteries of 60 patients. There was an expected increase in size and density values for mild versus moderate versus severe calcifications, but there was no difference in IVUS measured minimum lumen area among the 3 groups. Of note, coronary CTA significantly underestimated IVUS minimum lumen area measurement by 1.2 +/- 1.6 mm (14.6 +/- 23.1%, P < 0.001) for severe calcifications and by 0.5 +/- 2.0 mm (3.7 +/- 32.1%, P = 0.021) for moderate calcifications. Within mild calcifications, the difference was not significant. CONCLUSION: Based on their dimensional and radiodensity characteristics, our analysis revealed patterns of individual coronary artery calcifications that affected the accuracy of coronary CTA measurements; coronary CTA inaccuracy was associated with the presence of moderate or severe calcifications, but not mild calcifications. PMID- 29189399 TI - Performance of Magnetic Resonance Susceptibility-Weighted Imaging for Detection of Calcifications in Patients With Hepatic Echinococcosis. AB - OBJECTIVE: We evaluated the performance of susceptibility-weighted imaging (SWI) for identification of hepatic calcifications in alveolar echinococcosis and cystic echinococcosis. METHODS: The SWI images of 58 lesions in 40 patients (age, 49 +/- 14 y) with alveolar echinococcosis (n = 22) or cystic echinococcosis (n = 18) were reviewed for calcifications. First, calcifications were suggested by visual assessment. Second, ratios of minimum intralesional intensity and mean lumbar muscle intensity were recorded. Computed tomography (CT) served as the criterion standard. RESULTS: Thirty-seven lesions showed calcifications on CT. Susceptibility-weighted imaging provided a sensitivity of 89.2% (95% confidence interval [CI], 50.1-75.7) and a specificity of 57.1% (95% CI, 34.4-77.4) for calcifications detected by visual assessment. Receiver operating characteristic curves demonstrated a sensitivity of 67.6% and a specificity of 85.0% for an intensity ratio of 0.61. A specificity of 100% (95% CI, 80.8-100) and a sensitivity of 84.5% (95% CI, 67.3-93.2) were achieved by SWI for calcifications with a density greater than 184 HU in CT. CONCLUSIONS: Identification of hepatic calcifications is possible with SWI. Susceptibility-weighted imaging offers the potential to reduce the need for of CT imaging for evaluation of echinococcosis. PMID- 29189398 TI - Quantification of the Effect of Shuttling on Computed Tomography Perfusion Parameters by Investigation of Aortic Inputs on Different Table Positions From Shuttle-Mode Scans of Lung and Liver Tumors. AB - OBJECTIVES: The aim of this study was to quantify the effect of shuttling on computed tomography perfusion (CTp) parameters derived from shuttle-mode body CT images using aortic inputs from different table positions. METHODS: Axial shuttle mode CT scans were acquired from 6 patients (10 phases, 2 nonoverlapping table positions 1.4 seconds apart) after contrast agent administration. Artifacts resulting from the shuttling motion were corrected with nonrigid registration before computing CTp maps from 4 aortic levels chosen from the most superior and inferior slices of each table position scan. The effect of shuttling on CTp parameters was estimated by mean differences in mappings obtained from aortic inputs in different table positions. Shuttling effect was also quantified using 95% limits of agreement of CTp parameter differences within-table and between table aortic positions from the interaortic mean CTp values. RESULTS: Blood flow, permeability surface, and hepatic arterial fraction differences were insignificant (P > 0.05) for both within-table and between-table comparisons. The 95% limits of agreement for within-table blood volume (BV) value deviations obtained from lung tumor regions were less than 4.7% (P = 0.18) compared with less than 12.2% (P = 0.003) for between-table BV value deviations. The 95% limits of agreement of within-table deviations for liver tumor regions were less than 1.9% (P = 0.55) for BV and less than 3.2% (P = 0.23) for mean transit time, whereas between-table BV and mean transit time deviations were less than 11.7% (P < 0.01) and less than 14.6% (P < 0.01), respectively. Values for normal liver tissue regions were concordant. CONCLUSIONS: Computed tomography perfusion parameters acquired from aortic levels within-table positions generally yielded higher agreement than mappings obtained from aortic levels between-table positions indicating differences due to shuttling effect. PMID- 29189401 TI - Comparing Fourth Generation Statistical Iterative Reconstruction Technique to Standard Filtered Back Projection in Pediatric Head Computed Tomography Examinations. AB - OBJECTIVE: Although advanced statistical iterative reconstruction (IR) techniques are valued in pediatric computed tomography (CT) imaging, there is little published data on how these techniques affect image quality and radiation dose in the pediatric population. This is particularly true in the context of pediatric head CT examinations. This study analyzed the differences in image quality and several standard metrics of radiation dose on multidetector pediatric head CT examinations performed using standard filtered back projection (FBP) with reconstructions using iDose, a fourth-generation statistical iterative reconstruction technique. MATERIALS AND METHODS: Using a retrospective review of 282 pediatric head CT examinations, we compared how iDose fared against FBP for effects on several standard metrics of radiation dose and qualitative and quantitative assessment of image quality. RESULTS: Our assessment revealed that examinations obtained using low-dose protocols reconstructed using iDose, when compared with standard-dose examinations reconstructed using FBP, resulted in significant radiation dose reduction while performing equally or better in quantitative image quality parameters. For most qualitative image quality parameters, the iDose group demonstrated equal performance to standard filtered back technique with a few notable exceptions. In the parameter of image sharpness in the 1.5 to 7 year olds, iDose fared better than FBP. However, FBP outperformed iDose in the qualitative parameters of decreased image graininess/noise in patients older than 13 years, improved image sharpness in patients aged between 7 and 13 years, and improved visibility of small parts for those aged 7 to 13 years. CONCLUSIONS: We conclude that iDose is effective at allowing significant radiation dose reduction while maintaining or, rarely, even improving quantitative image quality compared with FBP in the setting of pediatric head CT examinations. However, for certain qualitative image quality parameters in older aged children, the use of iDose resulted in a poorer performance compared with FBP. PMID- 29189400 TI - Assessment of Myometrial Invasion in Premenopausal Grade 1 Endometrial Carcinoma: Is Magnetic Resonance Imaging a Reliable Tool in Selecting Patients for Fertility Preserving Therapy? AB - OBJECTIVES: The aim of this study was to evaluate the diagnostic ability of magnetic resonance imaging (MRI) in premenopausal women with G1 endometrial carcinoma. METHODS: Twenty-six patients underwent T2W, diffusion weighted, and dynamic contrast-enhanced 3-T MRI. The degree of myometrial invasion was pathologically classified into no invasion, shallow (3 mm or less), and more. Two radiologists assessed myometrial invasion on MRI. Diagnostic accuracy, sensitivity, specificity, positive and negative predictive values, AUC, and interobserver agreement were analyzed. RESULTS: For assessing myometrial invasion, mean accuracy, sensitivity, specificity, positive predictive values, negative predictive values, and AUC, respectively, were as follows: 63%, 42%, 85%, 79%, 47%, and 0.75. Mean interobserver agreement was fair (k = 0.36). Shallow invasions were underestimated as no invasion on MRI in all 6 cases. CONCLUSIONS: Magnetic resonance imaging produced false-negative result on half of patients. The misjudgments tended to happen in patients with shallow invasion. PMID- 29189402 TI - Correlation Between Semen Analysis Parameters and Diffusion-Weighted Magnetic Resonance Imaging of the Testicles in Patients With Varicocele: A Pilot Study. AB - PURPOSE: The aims of this study were to evaluate using testicle apparent diffusion coefficient (ADC) values in patients with varicocele and compare them with those of healthy individuals, to identify an optimal ADC threshold level to predict abnormal semen analysis using diffusion-weighted imaging. MATERIALS AND METHODS: Thirty-one patients with the diagnosis of varicocele and 20 healthy controls were enrolled in the study. All subjects underwent testicle diffusion weighted imaging at b values of 0, 400, and 800 s/mm and semen analysis. Student t tests were used to compare continuous variables between 2 groups. Testicle ADC values were correlated with semen analysis parameters. The relationship between ADC values and impaired semen analysis parameters was evaluated using Pearson correlation coefficient analysis. Receiver operating characteristic curves were formed. Cut-off values for ADC, sensitivity, and specificity values were measured. RESULTS: There was a negative correlation between mean ADC values and plexus pampiniformis vein diameter (r = -0.467, P < 0.001) and a positive correlation between mean ADC values and sperm count (r = 0.838, P < 0.001) as well as sperm morphology (r = 0.548, P < 0.05). Sensitivity values of 94.3% and 86.6% and specificity values of 87.5% and 43.8% were determined for the best cut off ADC values in diagnosing the sperm count and morphology, respectively (area under the curve, 0.961 and 0.781). CONCLUSIONS: Decreased testicular ADC values in patients with varicocele are significantly correlated with semen parameters. This method may be used to determine the degree of testicular parenchymal destruction. In addition, testicular ADC cut-off values might be useful in dyspermia patients for the management of patients with varicocele. PMID- 29189403 TI - How Do Different Indices of Hepatic Enhancement With Gadoxetic Acid Compare in Predicting Liver Failure and Other Major Complications After Hepatectomy? AB - OBJECTIVE: The objective of this study was to assess the accuracy of gadoxetic acid hepatic enhancement indices in predicting posthepatectomy liver failure (PHLF) and other major complications (OMCs). METHODS: Sixty-five patients underwent prehepatectomy gadoxetic acid-enhanced magnetic resonance imaging. Enhancement indices were calculated by obtaining regions of interest on magnetic resonance images and segmented volumes of the liver and spleen. Multivariate regression analysis was performed to predict PHLF and OMC as a function of the indices, and areas under the receiver operator characteristic (AUROC) curves were calculated. RESULTS: Areas under the receiver operator characteristic values varied from 0.412 to 0.681 and 0.462 to 0.738 in predicting PHLF and OMC, respectively. The most accurate indices in predicting PHLF were the region of interest-based, fat-normalized relative liver enhancement and liver enhancement index (AUROC, 0.681). The most accurate index in predicting OMC was the volumetric least-squares regression slope of a pharmacokinetic model (Khep_V, AUROC, 0.738). CONCLUSIONS: Indices of gadoxetic acid liver enhancement demonstrate variable performance in predicting PHLF and OMC. PMID- 29189404 TI - Artifactual Appearance of Thrombosis on Using Metal Artifact Reduction Software Reconstruction in Computed Tomographic Angiography. AB - The authors attempted to use metal artifact reduction software in 2 computed tomographic angiogram studies to decrease beam hardening. Although the beam hardening artifacts were reduced in the postprocessed images, there was an artifactual appearance of thrombosis in the adjacent arteries in the first case and in the inflow cannula of a left ventricular assist device in the second case. Comparison of the reconstructed images with the original images is therefore essential to avoid a misdiagnosis. PMID- 29189405 TI - Intrahepatic Mass-Forming Cholangiocarcinoma: Relationship Between Computed Tomography Characteristics and Histological Subtypes. AB - OBJECTIVE: The aim of this study was to determine the value of multi-detector row computed tomography (MDCT) in differentiating the small-duct (SD) and large-duct (LD) types of intrahepatic mass-forming cholangiocarcinomas (IMCCs) and predicting patient prognosis. METHODS: The 4-phase MDCT image findings of 82 patients with surgically confirmed IMCCs (60 SD-type and 22 LD-type IMCCs) were compared between 2 types using univariate and multivariate analyses. Overall survival rates for 78 patients with available information were compared using the Kaplan-Meier method. RESULTS: Arterial hyperenhancement, round or lobulated contour, and lack of bile duct encasement were significant MDCT features suggesting the SD type, and lymph node enlargement was significantly associated with the LD type (all P's < 0.05). The presence of those 3 SD-type-suggestive features (MDCT-suggested SD type) demonstrated high specificity (90.9% [20/22]) in differentiating the SD type. Patients of MDCT-suggested SD type without lymph node enlargement (n = 24) demonstrated significantly better overall survival than other groups. CONCLUSIONS: Preoperative MDCT features of IMCCs can help differentiate the SD and LD types and predict patient prognosis. PMID- 29189406 TI - Cleidocranial Dysplasia: A Review of Clinical, Radiological, Genetic Implications and a Guidelines Proposal. AB - In this review, we aimed to depict the clinical, radiological, and genetic features of cleidocranial dysplasia (CCD) and to suggest management guidelines, based on our experience of 8 cases, with an emphasis given to dental complications.The most common craniofacial features of CCD that stand out are a patency of the anterior fontanelle, an inverted pear-shaped calvaria, a hypertelorism, a general midface retrusion, and a mandible prognathism, associated with an excessive mobility of the shoulders, a short stature, and teeth abnormalities such as supernumerary teeth and failure of eruption, in particular. RUNX2 is the only gene in which mutation is known to cause CCD, but mutations are detected in only 65% of all patients with a clinical diagnosis of CCD. Panoramic radiography is a valuable adjunct in confirming the diagnosis of CCD.Our experience allowed us to conclude that orthodontically aided eruption should always be attempted. However, to stabilize the occlusion and to improve facial esthetics, we recommend associated orthognathic surgery. When orthodontic treatment is partially efficient, prosthetic treatment options bring satisfactory results, in terms of occlusion. Nevertheless, when orthodontic treatment fails, we recommend to preserve as many native teeth as possible, and to combine orthognathic preprosthetic surgery and implant-supported prosthesis.In any case, an individualized treatment protocol, depending on the needs and demand of the patient, the age at diagnosis and social and economic circumstances, should be put forward. PMID- 29189407 TI - Effect of Resistance Training to Muscle Failure vs. Volitional Interruption at High- and Low-Intensities on Muscle Mass and Strength. AB - Nobrega, SR, Ugrinowitsch, C, Pintanel, L, Barcelos, C, and Libardi, CA. Effect of resistance training to muscle failure vs. volitional interruption at high- and low-intensities on muscle mass and strength. J Strength Cond Res 32(1): 162-169, 2018-The purpose of this study was to investigate the effects of resistance training (RT) at high- and low-intensities performed to muscle failure or volitional interruption on muscle strength, cross-sectional area (CSA), pennation angle (PA), and muscle activation. Thirty-two untrained men participated in the study. Each leg was allocated in 1 of 4 unilateral RT protocols: RT to failure at high and low intensities, and RT to volitional interruption (repetitions performed to the point in which participants voluntarily interrupted the exercise) at high (HIRT-V) and low (LIRT-V) intensities. Muscle strength (1 repetition maximum [1RM]), CSA, PA, and muscle activation by amplitude of the electromyography (EMG) signal were assessed before (Pre), after 6 (6W), and 12 (12W) weeks. 1RM increased similarly after 6W (range: 15.8-18.9%, effective size [ES]: 0.41-0.58) and 12W (range: 25.6-33.6%, ES: 0.64-0.98) for all protocols. All protocols were similarly effective in increasing CSA after 6W (range: 3.0 4.6%, ES: 0.10-0.24) and 12W (range: 6.1-7.5%, ES: 0.22-0.26). PA increased after 6W (~3.5) and 12W (~9%; main time effect, p < 0.0001), with no differences between protocols. EMG values were significantly higher for the high-intensity protocols at all times (main intensity effect, p < 0.0001). In conclusion, both HIRT-V and LIRT-V are equally effective in increasing muscle mass, strength, and PA when compared with RT performed to muscle failure.

PMID- 29189410 TI - Health and Well-Being Metrics in Business: The Value of Integrated Reporting. AB - OBJECTIVE: Health and well-being (HWB) are material to sustainable business performance. Yet, corporate reporting largely lacks the intentional inclusion of HWB metrics. This brief report presents an argument for inclusion of HWB metrics into existing standards for corporate reporting. METHODS AND RESULTS: A Core Scorecard and a Comprehensive Scorecard, designed by a team of subject matter experts, based on available evidence of effectiveness, and organized around the categories of Governance, Management, and Evidence of Success, may be integrated into corporate reporting efforts. CONCLUSIONS: Pursuit of corporate integrated reporting requires corporate governance and ethical leadership and values that ultimately align with environmental, social, and economic performance. Agreement on metrics that intentionally include HWB may allow for integrated reporting that has the potential to yield significant value for business and society alike. PMID- 29189411 TI - Diverse roles of TIM4 in immune activation: implications for alloimmunity. AB - PURPOSE OF REVIEW: T-cell immunoglobulin and mucin domain-containing molecule (TIM)4 is a costimulatory molecule and phosphatidylserine receptor. Its dominant function varies according to the expressing cell and site of activation. In recent years, studies have identified its role in diverse disease processes and increasingly in alloimmunity. Herein, we will comprehensively review the literature on TIM4 and outline its function in shaping the alloimmune response. RECENT FINDINGS: TIM4 expression on dendritic cells increases following transplantation. Blockade of TIM4 in vivo leads to increased differentiation of regulatory T cells and improved allograft survival. TIM4 binds phosphatidylserine expressing apoptotic cells. Previously thought of as a tethering molecule, recent studies have demonstrated that TIM4 interacts with integrins to mediate uptake of apoptotic cells. TIM4 B cells have recently been identified, which produce high levels of IFNgamma and promote allograft rejection. Targeting these B cells improved allograft survival and promoted the development of TIM1 regulatory B cells. SUMMARY: TIM4 is expressed in niche compartments and has many immunological effects. However, inhibition of TIM4 has been demonstrated to prolong allograft survival, through varied mechanisms. A unifying explanation for the role of TIM4 in alloimmunity remains to be found, but this pathway appears to hold considerable promise in transplantation. PMID- 29189412 TI - Harnessing the lymph node microenvironment. AB - PURPOSE OF REVIEW: To evaluate role of the lymph node in immune regulation and tolerance in transplantation and recent advances in the delivery of antigen and immune modulatory signals to the lymph node. RECENT FINDINGS: Lymph nodes are a primary site of immune cell priming, activation, and modulation, and changes within the lymph node microenvironment have the potential to induce specific regulation, suppression, and potentially tolerance. Antigen enters the lymph node either from tissues via lymphatics, from blood via high endothelial venules, or directly via injection. Here we review different techniques and materials to deliver antigen to the lymph node including microparticles or nanoparticles, ex vivo antigen presenting cell manipulation, and use of receptor conjugation for specific intralymph node targeting locations. SUMMARY: The promising results point to powerful techniques to harness the lymph node microenvironment and direct systemic immune regulation. The materials, techniques, and approaches suggest that translational and clinical trials in nonhuman primate and patients may soon be possible.

AB - PURPOSE: To investigate the osteoconductive effect of a chitosan scaffold in a rat skull defect model. Previous publications have demonstrated the osteoinductive properties as scaffold materials with growth factors; however, whether chitosan alone has osteoconductive ability is unclear. This study used cross-linked chitosan scaffolds for in vivo evaluation of scaffold-supported bone regeneration in rat calvarial defects using histopathological analysis and examination of alkaline phosphatase (ALP), calcium, phosphorus, and calcitonin serum levels. MATERIALS AND METHODS: Scaffolds were made of cross-linked chitosan. After the defect was filled with the scaffold, the periosteum was carefully repositioned and sutured to stabilize the scaffold. The effects of the scaffold on wound repair were examined microscopically. Morphological radiographic and histopathological analyses of wound repair ratios were performed at 3 and 4 weeks after the defects were made. RESULTS: Using the cross-linked chitosan biomaterial of the wounds. The amount of regenerated bone measured was significantly greater in the chitosan-treated group than in the control group. The ALP level in the chitosan group at 4 weeks was higher than at baseline and at the 4-week follow-up in the control group (P < 0.05). CONCLUSIONS: The results show that cross-linked chitosan has an osteoconductive effect on bone regeneration in vivo.

AB - PURPOSE OF REVIEW: This article reviews recent literature on the nature of extracellular vesicles released by allogeneic transplants and examine their role in T-cell alloimmunity involved in rejection and tolerance of these grafts. RECENT FINDINGS: Donor cells release extracellular vesicles, including exosomes, after transplantation of allogeneic organs and tissues. Consequently, recipient APCs take up these exosomes and present donor MHC antigens on their surface (allo MHC cross-dressing) thus, activating some alloreactive T cells via a mechanism called semi-direct pathway of allorecognition. In addition, one study shows that exosomes carrying noninherited maternal antigens are associated with maternal microchimerism and tolerance in offspring. Finally, a few studies describe potential utilization of exosomes as modulators of alloimmunity and biomarkers of rejection in allotransplantation. SUMMARY: Extracellular vesicles, including exosomes, released by allografts contribute to recognition of donor antigens by T cells after allotransplantation. This occurs through cross-dressing of recipient APCs with donor MHC antigens and subsequent activation of T cells, a process called semi-direct alloreactivity. The relevance of this phenomenon in rejection and tolerance of allografts and the potential utilization of exosomes as biomarkers in transplantation are discussed. PMID- 29189416 TI - The Treatment Cascade in Children With Unsuppressed Viral Load-A Reality Check in Rural Lesotho, Southern Africa. AB - BACKGROUND: As per the guidelines of the World Health Organization, HIV-infected children who do not achieve viral suppression while under antiretroviral therapy (ART) receive enhanced adherence counseling (EAC) with follow-up viral load (VL). A persisting unsuppressed VL after EAC triggers switch to a second-line regimen. We describe the care cascade of children with unsuppressed VL while taking ART. METHODS: Children, aged <16 years, on first-line ART for >=6 months with unsuppressed VL (>=80 copies/mL) at first measurement were enrolled. As per guidelines, children/caregivers received EAC and a follow-up VL after 3 months, whereas those with persisting viremia despite good adherence were eligible for switching to second-line. Eighteen months after the first unsuppressed VL, outcomes were assessed. RESULTS: Of 191 children receiving a first-time VL in May/June 2014, 53 (28%) had unsuppressed viremia. The care cascade of these 53 children was as follows: 49 (92%) received EAC and a follow-up VL in October 2014 (1 died, 3 lost to follow-up). 36/49 (73%) stayed unsuppressed, but only 24 were switched to second-line. At 18-months follow-up, 10 (19%) were retained in care with suppressed VL, 26 were retained with ongoing viremia (49%), 2 (4%) had died, and 15 (28%) had no VL documentation. CONCLUSIONS: Only 1 of 5 children with unsuppressed initial VL under ART was retained in care and virally suppressed at 18 months of follow-up. ART programs must increase the focus onto the extremely vulnerable care cascade in children with unsuppressed VL. PMID- 29189417 TI - Brief Report: Adherence Biomarker Measurements in Older and Younger HIV-Infected Adults Receiving Tenofovir-Based Therapy. AB - BACKGROUND: Concentrations of tenofovir (TFV) in hair and tenofovir diphosphate (TFV-DP) in dried blood spots (DBSs) as measures of cumulative exposure have been primarily studied in younger, HIV-uninfected individuals taking preexposure HIV prophylaxis. Data on these measures among older HIV-infected individuals are limited. METHODS: We evaluated longitudinal TFV and TFV-DP concentrations in hair and DBS, respectively, from HIV-infected adults. Multivariable model variables included age group (18-35 and 60 years and older), creatinine clearance (CrCl), hematocrit (TFV-DP), and gray hair color (TFV). RESULTS: Baseline hair TFV and DBS TFV-DP were moderately correlated [r = 0.5 (0.2 to 0.7); P = 0.001] across both age groups [younger (N = 23) and older (N = 22)]. In adjusted models, CrCl was associated with increases of 15.9% (7.4% to 25.0%); P = 0.0006, and 5.7% ( 0.2% to 11.9%); P = 0.057 for TFV in hair and TFV-DP in DBS, respectively, for every 20-mL/min CrCl decrease. Although older age (versus younger age) was univariately associated with increased TFV hair levels, older age was not significantly associated with higher concentrations in hair [-1.4% (-26.7% to 32.7%); P = 0.93] or DBS [4.0% (-14.1% to 25.9%); P = 0.68] after adjustment. Similarly, gray color was not significantly associated with higher TFV levels in hair [27.6% (-11.1% to 83.0%; P = 0.18)] in adjusted models. In both adjusted and unadjusted models of TFV-DP levels in DBS, a 1% hematocrit increase was associated with a 3.3% (0.2% to 6.5%) TFV-DP increase (P = 0.04). CONCLUSIONS: Cumulative drug exposure measures (hair and DBS) were comparable in younger and older HIV-infected individuals on TFV-based therapy after adjustment for renal function.

PMID- 29189420 TI - Neostigmine-based reversal of intermediate acting neuromuscular blocking agents to prevent postoperative residual paralysis: A systematic review. AB - BACKGROUND: Neostigmine is widely used to antagonise residual paralysis. Over the last decades, the benchmark of acceptable neuromuscular recovery has increased progressively to a train-of-four (TOF) ratio of at least 0.9. Raising this benchmark may impact on the efficacy of neostigmine. OBJECTIVE(S): The systematic review evaluates the efficacy of neostigmine to antagonise neuromuscular block to attain a TOF ratio of at least 0.9. DESIGN: We performed a systematic search of the literature from January 1992 to December 2015. DATA SOURCES OR SETTING: PubMed, EMBASE and the Cochrane Controlled Clinical Trials database were searched for randomised controlled human studies. Search was performed without language restrictions, using the following free text terms: 'neostigmine', 'sugammadex', 'edrophonium' or 'pyridostigmine' AND 'neuromuscular block', 'reversal' or 'reverse'. ELIGIBILITY CRITERIA: Studies were accepted for inclusion if they used quantitative neuromuscular monitoring and neostigmine as the reversal agent. Selected trials were checked by two of the authors for data integrity. Trials relevant for inclusion had to report the number of patients included, the type of anaesthetic maintenance, the type of neuromuscular blocking agent used, the reversal agent and dose used, the depth of neuromuscular block when neostigmine was administered and the reversal time (time from injection of neostigmine until a TOF ratio >=0.9 was attained). RESULTS: 19 trials were eligible for quantitative analysis. In patients with deep residual block [T1 (first twitch height) <10%] 70 MUg kg neostigmine was used (five trials, 118 patients), and the mean reversal time was 17.1 min (95% confidence interval (CI) [12.4 to 21.8]). In patients with moderate residual block (T1 10% to <25%) the mean neostigmine dose was 56 MUg kg (seven trials, 342 patients), and the mean reversal time was 11.3 min (95% CI [9.2 to 13.4]). In patients with a shallow residual block (T1 >= 25%) the mean neostigmine dose was 40 MUg kg (13 trials, 535 patients), and the mean reversal time was 8.0 min (95% CI [6.8 to 9.2]). CONCLUSION: Based on the findings of this systematic review, we recommend that the administration of neostigmine be delayed until an advanced degree of prereversal recovery has occurred (i.e. a T1 >25% of baseline), or that a recovery time longer than 15 min be accepted. PMID- 29189422 TI - Extracorporeal Membrane Oxygenation in Premature Infants With Congenital Diaphragmatic Hernia. AB - Prematurity and low birth weight have been exclusion criteria for extracorporeal membrane oxygenation (ECMO); however, these criteria are not evidence based. With advances in anticoagulation, improved technology, and surgical expertise, it is difficult to deny a potential therapy based on these criteria alone. We report the outcome of three neonates who were ineligible based on traditional criteria but were offered ECMO as a life-saving measure. We highlight the interdisciplinary nature of modern decision-making. All three neonates had severe congenital diaphragmatic hernia diagnosed prenatally, had normal fetal karyotypes, were born prematurely, and weighed less than 2 kg. All three neonates underwent cervical venoarterial cannulation, stabilization on ECMO, and repair of their congenital diaphragmatic hernia early in their ECMO courses. All three infants had long courses of respiratory support attributable to lung hypoplasia, but there were no short- or long-term complications attributable to ECMO support directly. All three are alive at 2 years of age and were making progress developmentally. In conclusion, with interdisciplinary collaboration and clinical guidelines uniformly implemented, low birth weight infants may benefit from ECMO and should not be denied the therapy arbitrarily based on gestational age or size alone. Further research is essential to determine appropriate patient selection in premature infants. PMID- 29189421 TI - Asenapine in the management of impulsivity and aggressiveness in bipolar disorder and comorbid borderline personality disorder: an open-label uncontrolled study. AB - Borderline personality disorder (BPD) often co-occurres with bipolar disorder (BD). Impulsivity and aggressiveness represent core shared features and their pharmacological management is mainly based on mood stabilizers and antipsychotics, although scarce evidence is available for this context of comorbidity. The aim of the present study was to evaluate the role of Asenapine as an adjunctive drug for reducing aggressiveness and impulsivity in a sample of Italian BD type I outpatients with or without a comorbid BPD. This was an observational 12-week open-label uncontrolled clinical study carried out from April to October 2014 in two psychiatric clinics in Sicily. Each patient was treated with asenapine at two dose options, 5 mg (twice daily) or 10 mg (twice daily), and concomitant ongoing medications were not discontinued. We measured impulsivity using the Barratt Impulsiveness Scale (BIS) and aggressiveness using the Aggressive Questionnaire (AQ). For the analysis of our outcomes, patients were divided into two groups: with or without comorbid BPD. Adjunctive therapy was associated with a significant decrease of BIS and AQ overall scores in the entire bipolar sample. Yet, there was no significant difference in BIS and AQ reductions between subgroups. Using a regression model, we observed that concomitant BPD played a negative role on the Hostility subscale and overall AQ score variations; otherwise, borderline co-diagnosis was related positively to the reduction of physical aggression. According to our post-hoc analysis, global aggressiveness scores are less prone to decrease in patients with a dual diagnosis, whereas physical aggressiveness appears to be more responsive to the add-on therapy in patients with comorbidity. PMID- 29189423 TI - The Boy in the Bubble and the Baby With the Berlin Heart: The Dangers of "Bridge to Decision" in Pediatric Mechanical Circulatory Support. AB - On the day of his birth in 1971, David Vetter was "temporarily" placed in a sterile isolator to wait for a bone marrow donor who would cure his Severe Combined Immunodeficiency Syndrome. After enduring 12 years in isolation, David, now known to the world as "The Boy in the Bubble", received a bone marrow transplant from his unmatched sister and died 4 months later. Like Severe Combined Immunodeficiency Syndrome, pediatric heart failure is a rare and life threatening condition for which organ transplantation is often the only option for survival. Nearly 15 years ago, the Berlin Heart EXCOR ventricular assist device was developed, as the isolator was for David, to be a bridge to transplantation for infants and children with unstable heart failure. Yet, when symptoms progress faster than the patient's suitability for transplant can be evaluated, this device may be implanted as a "bridge-to-decision" while a transplant evaluation is completed. Therein lies the potential for history to repeat itself. As biomedical science carries us ever forward in our ability to sustain life, we must always bear in mind that the miraculous EXCOR must not be a machine that simply sustains the circulation. It must be, and always remain, a bridge to somewhere. PMID- 29189424 TI - iPhone in the Management of the Berlin Heart EXCOR Ventricular Assist Device. AB - Berlin Heart Inc. EXCOR is an extracorporeal pneumatically pulsatile ventricular assist device approved for use in pediatric age group since 2011 in the United States. It is a well-established life-saving therapy for the bridge to heart transplant or to provide circulatory support in a transplanted patient. The most commonly reported problem was "membrane defect" in a postmarketing major device reporting. In general, the filling and emptying of the pump can be easily visualized, but the interobserver variability exist. In this first novel report, we used the iPhone slow motion video to quantify and compare the differences in filling and emptying that positively impacted the management of the Berlin Heart. This is an initial exploratory concept that will need further studies to validate this bedside tool. PMID- 29189425 TI - Remodeling Failing Human Myocardium With Hybrid Cell/Matrix and Transmyocardial Revascularization. AB - Given the limited treatment options for advanced heart failure, the intrinsic regenerative properties of stem cells have been evaluated for myocardial remodeling. Previous stem cells techniques for myocardiocyte remodeling have been limited by the low cellular retention. Presented is a hybrid approach for remodeling infarcted myocardium through implantation of allogeneic human amniotic fluid-derived mesenchymal stem cells within micronized human allograft-derived liquid matrix during the performance of transmyocardial revascularization (TMR). Given the induced increase in vascular density from TMR, we hypothesize that it may serve as a therapeutic delivery system for stem cell placement into damaged myocardium. We present a patient with ischemic cardiomyopathy and refractory angina, who clinically improved after this hybrid therapy of intraoperative TMR and placement of amniotic fluid-derived mesenchymal stem cells and liquid matrix within the TMR channels. Noninvasive testing of myocardial viability biomarkers utilizing both cardiac magnetic resonance imaging and thallium imaging supported the clinical improvement in cardiac symptom may be related to ventricular remodeling in a region of infarct with subsequent functional improvement. PMID- 29189426 TI - The Influence of Exercise on Cardiovascular Health in Sedentary Adults With Human Immunodeficiency Virus. AB - BACKGROUND: Lifestyle physical activity (ie, moderate physical activity during routine daily activities most days of the week) may benefit human immunodeficiency virus (HIV)-positive adults who are at high risk for cardiovascular disease. OBJECTIVE: The aims of this study were to describe lifestyle physical activity patterns in HIV-positive adults and to examine the influence of lifestyle physical activity on markers of cardiovascular health. Our secondary objective was to compare these relationships between HIV-positive adults and well-matched HIV-uninfected adults. METHODS: A total of 109 HIV positive adults and 20 control participants wore an ActiGraph accelerometer, completed a maximal graded cardiopulmonary exercise test, completed a coronary computed tomography, completed anthropomorphic measures, and had lipids and measures of insulin resistance measured from peripheral blood. RESULTS: Participants (N = 129) had a mean age of 52 +/- 7.3 years, 64% were male (n = 82), and 88% were African American (n = 112). On average, HIV-positive participants engaged in 33 minutes of moderate-to-vigorous physical activity per day (interquartile range, 17-55 minutes) compared with 48 minutes in controls (interquartile range, 30-62 minutes, P = .05). Human immunodeficiency virus positive adults had poor fitness (peak oxygen uptake [VO2], 16.8 +/- 5.2 mL/min per kg; and a ventilatory efficiency, 33.1 [4.6]). A marker of HIV disease (current CD4+ T cell) was associated with reduced peak VO2 (r = -0.20, P < .05) and increased insulin resistance (r = 0.25, P < .01) but not with physical activity or other markers of cardiovascular health (P >= 0.05). After controlling for age, gender, body mass index, and HIV status, physical activity was not significantly associated with peak VO2 or ventilatory efficiency. CONCLUSION: Human immunodeficiency virus-positive adults have poor physical activity patterns and diminished cardiovascular health. Future longitudinal studies should examine whether HIV infection blunts the beneficial effects of physical activity on cardiovascular health. PMID- 29189427 TI - Self-efficacy Mediates the Relationship Between Motivation and Physical Activity in Patients With Heart Failure. AB - BACKGROUND: Motivation is necessary in patients with heart failure (HF) who are attempting to become more physically active but may not be sufficient to initiate physical activity. Self-efficacy might explain the relationship between motivation and physical activity. OBJECTIVE: The aim of this study was to examine the role of exercise self-efficacy in the relationship between exercise motivation and physical activity in patients with HF. METHODS: A total of 100 stable patients with HF (88% in New York Heart Association class II/III; mean age, 67 +/- 13 years; 62% men) were studied. Self-efficacy was measured with the Exercise Self-Efficacy Scale; motivation, with the Exercise Motivation Index; and physical activity, with a self-report questionnaire. Logistic regression analyses were made to examine the mediation effect of exercise self-efficacy on the relationship between exercise motivation and physical activity. RESULTS: Forty two percent of the 100 patients reported engaging in less than 60 minutes per week of physical activity. Motivation predicted physical activity (b = 0.58, P < .05), but after controlling for self-efficacy, the relationship between motivation and physical activity was no longer significant (b = 0.76, P = .06), indicating full mediation. CONCLUSION: Motivation to be physically active is important but not sufficient. In addition to a high level of motivation to be physically active, it is important that patients with HF have a high degree of self-efficacy. PMID- 29189428 TI - Wake-up Call to Clinicians: The Impact of Sleep Dysfunction on Gastrointestinal Health and Disease. AB - Sleep dysfunction is an epidemic affecting a large portion of the adult population. Recent studies have linked sleep dysfunction with an upregulation of proinflammatory cytokines (eg, tumor necrosis factor-alpha, interleukin-1 and interleukin-6), the implications of which can have a profound impact on a variety of gastrointestinal disease. In particular, sleep dysfunction seems to accelerate disease states characterized by inflammation (eg, gastroesophageal reflux disease, irritable bowel syndrome and functional dyspepsia, chronic liver disease, inflammatory bowel disease, and colorectal cancer). This article evaluates the complex interplay between sleep dysfunction and gastrointestinal health and disease. PMID- 29189429 TI - New developments in immunotherapy for pediatric solid tumors. AB - PURPOSE OF REVIEW: Building upon preclinical advances, we are uncovering immunotherapy strategies that are translating into improved outcomes in tumor subsets. Advanced pediatric solid tumors carry poor prognoses and resultant robust efforts to apply immunotherapy advances to pediatric solid tumors are in progress. Here, we discuss recent developments in the field using mAb and mAb based therapies including checkpoint blockade and chimeric antigen receptors (CARs). RECENT FINDINGS: The pediatric solid tumor mAb experience targeting the diganglioside, GD2, for patients with neuroblastoma has been the most compelling to date. GD2 and alternative antigen-specific mAbs are now being incorporated into antibody-drug conjugates, bispecific antibodies and CARs for treatment of solid tumors. CARs in pediatric solid tumors have not yet achieved comparative responses to the hematologic CAR experience; however, novel strategies such as bispecific targeting, intratumoral administration and improved understanding of T cell biology may yield enhanced CAR-efficacy. Therapeutic effect using single agent checkpoint blocking antibodies in pediatric solid tumors also remains limited to date. Combinatorial strategies continue to hold promise and the clinical effect in tumor subsets with high antigenic burden is being explored. SUMMARY: Pediatric immunotherapy remains at early stages of translation, yet we anticipate that with advanced technology, we will achieve widespread, efficacious use of immunotherapy for pediatric solid tumors. PMID- 29189430 TI - Precision medicine in pediatric oncology. AB - PURPOSE OF REVIEW: The current review describes recent advances and unique challenges in precision medicine for pediatric cancers and highlights clinical trials assessing the clinical impact of targeted therapy matched to molecular alterations identified by tumor profiling. RECENT FINDINGS: Multiple prospective clinical sequencing studies in pediatric oncology have been reported in the last 2 years. These studies demonstrated feasibility of sequencing in the clinic and revealed a rate of actionable variants that justifies the development of precision trials for childhood cancer. A number of precision medicine trials are recently completed, underway or in development and these will be reviewed herein, with a focus on highlighting aspects of precision medicine trial design relevant to pediatric oncology. SUMMARY: The primary results of the first round of pediatric precision oncology clinical trials will provide us with a greater understanding of the clinical impact of linking tumor profiling to selection of targeted therapies. The aggregation of sequencing and clinical data from these trials and the results of biologic investigations linked to these trials will drive further discoveries and broaden opportunities for precision medicine for children with cancer. PMID- 29189432 TI - The South African English Smartphone Digits-in-Noise Hearing Test: Effect of Age, Hearing Loss, and Speaking Competence. AB - OBJECTIVES: This study determined the effect of hearing loss and English-speaking competency on the South African English digits-in-noise hearing test to evaluate its suitability for use across native (N) and non-native (NN) speakers. DESIGN: A prospective cross-sectional cohort study of N and NN English adults with and without sensorineural hearing loss compared pure-tone air conduction thresholds to the speech reception threshold (SRT) recorded with the smartphone digits-in noise hearing test. A rating scale was used for NN English listeners' self reported competence in speaking English. This study consisted of 454 adult listeners (164 male, 290 female; range 16 to 90 years), of whom 337 listeners had a best ear four-frequency pure-tone average (4FPTA; 0.5, 1, 2, and 4 kHz) of <=25 dB HL. RESULTS: A linear regression model identified three predictors of the digits-in-noise SRT, namely, 4FPTA, age, and self-reported English-speaking competence. The NN group with poor self-reported English-speaking competence (<=5/10) performed significantly (p < 0.01) poorer than the N and NN (>=6/10) groups on the digits-in-noise test. Screening characteristics of the test improved with separate cutoff values depending on English-speaking competence for the N and NN groups (>=6/10) and NN group alone (<=5/10). Logistic regression models, which include age in the analysis, showed a further improvement in sensitivity and specificity for both groups (area under the receiver operating characteristic curve, 0.962 and 0.903, respectively). CONCLUSIONS: Self-reported English-speaking competence had a significant influence on the SRT obtained with the smartphone digits- in-noise test. A logistic regression approach considering SRT, self-reported English-speaking competence, and age as predictors of best ear 4FPTA >25 dB HL showed that the test can be used as an accurate hearing screening tool for N and NN English speakers. The smartphone digits-in-noise test, therefore, allows testing in a multilingual population familiar with English digits using dynamic cutoff values that can be chosen according to self-reported English-speaking competence and age. PMID- 29189431 TI - Psychosocial Outcomes in Long-Term Cochlear Implant Users. AB - OBJECTIVES: The objectives of this study were to investigate psychosocial outcomes in a sample of prelingually deaf, early-implanted children, adolescents, and young adults who are long-term cochlear implant (CI) users and to examine the extent to which language and executive functioning predict psychosocial outcomes. DESIGN: Psychosocial outcomes were measured using two well-validated, parent completed checklists: the Behavior Assessment System for Children and the Conduct Hyperactive Attention Problem Oppositional Symptom. Neurocognitive skills were measured using gold standard, performance-based assessments of language and executive functioning. RESULTS: CI users were at greater risk for clinically significant deficits in areas related to attention, oppositional behavior, hyperactivity-impulsivity, and social-adaptive skills compared with their normal hearing peers, although the majority of CI users scored within average ranges relative to Behavior Assessment System for Children norms. Regression analyses revealed that language, visual-spatial working memory, and inhibition concentration skills predicted psychosocial outcomes. CONCLUSIONS: Findings suggest that underlying delays and deficits in language and executive functioning may place some CI users at a risk for difficulties in psychosocial adjustment. PMID- 29189433 TI - Transintestinal cholesterol excretion in humans. AB - PURPOSE OF REVIEW: To discuss recent insights into the measurement and cellular basis of transintestinal cholesterol excretion (TICE) in humans and to explore TICE as a therapeutic target for increasing reverse cholesterol transport. RECENT FINDINGS: TICE is the net effect of cholesterol excretion by the enterocyte into the intestinal lumen and is the balance between input and output fluxes through the enterocytes. These fluxes are: cholesterol excretion into the intestinal lumen mainly via ATP-binding cassette (ABC) G5/8, cholesterol absorption from the intestine by Niemann-Pick C1 like protein 1, the uptake of plasma lipoproteins by enterocytes at the basolateral membrane, and the excretion of cholesterol in chylomicrons into the lymph. Multiple studies have shown that TICE contributes to fecal neutral sterol (FNS) excretion in humans. TICE can be targeted with plant sterols, liver X receptor agonists, bile acids, ezetimibe, and proprotein convertase subtilisin/kexin type 9 inhibitors. SUMMARY: TICE contributes significantly to FNS excretion in humans, independently of the biliary pathway. Knowledge about its underlying cellular mechanisms surges through in-vivo and in vitro studies in mice and humans. TICE might be an interesting therapeutic target for increasing cholesterol disposal with the feces. Albeit multiple therapeutic options are available, studies showing clinical benefit are still needed. PMID- 29189435 TI - Investigating Physicians' Views on Soft Signals in the Context of Their Peers' Performance. AB - BACKGROUND: Physicians are responsible for delivering high quality of care. In cases of underperformance, hindsight knowledge indicates forewarning being potentially available in terms of concerns, signs, or signals. It is not known how the physicians involved perceive such signals. PURPOSE: To openly explore how physicians perceive soft signals and react on them. METHODS: In-depth interviews with 12 hospital-based physicians from various specialties and institutions following the interpretative phenomenological analysis approach. RESULTS: Physicians perceive soft signals as an observable deviation from a colleague's normal behavior, appearance, or communication. Once observed, they evaluate the signal by reflecting on it personally and/or by consulting others, resulting in either an active (i.e., speaking up) or passive (i.e., avoidance) reaction. Observer sensitivity, closeness to the peer, and cohesion of the physician group influence this observation-evaluation-reaction process. CONCLUSIONS AND IMPLICATIONS: Physicians perceive soft signals as indicators of well-being and collegiality, not as concerns about performance or patient safety. They feel it is their responsibility to be sensitive to and deal with expressed signals. Creating a psychological safe culture could foster such an environment. Because a threat to physicians' well-being may indirectly affect their professional performance, soft signals require serious follow-up. PMID- 29189436 TI - Offering eConsult to Family Physicians With Patients on a Pain Clinic Wait List: An Outreach Exercise. AB - Wait times for many chronic pain programs in Canada range from 6 months to 2 years. This project sought to determine the interest of primary care providers (PCPs) in using an electronic consult system for patient(s) waiting for a pain consultation. This cross-sectional study was conducted at the pain clinic of a Canadian tertiary academic health sciences center. Participants were PCPs who had submitted a referral to this clinic. Referrals received between April 1, 2012, and March 31, 2014, were reviewed to determine their appropriateness for eConsult, and a letter providing information about eConsult and encouraging its use was sent to the referring PCP. Of the 585 referrals that were reviewed, 227 were appropriate for eConsult. Fifty-one (26%) of the 194 PCP responses received were positive. Technologies like eConsult may help address the growing demand for specialist advice. In addition to facilitating response to specific questions, the bidirectional nature of eConsult permits its use for educating PCPs about chronic pain treatment. Given that almost one third of responding PCPs indicated an interest in eConsult, its potential reach is vast. Additional study is needed to understand barriers to PCP acceptance and use of eConsult and the uptake of advice given. PMID- 29189437 TI - Postoperative Respiratory Failure. PMID- 29189438 TI - Perioperative Fluid Strategies to Prevent Lung Injury. PMID- 29189439 TI - Leading Causes of Anesthesia-Related Liability Claims in Ambulatory Surgery Centers. AB - OBJECTIVE: We present a contemporary analysis of patient injury, allegations, and contributing factors of anesthesia-related closed claims, which involved cases that specifically occurred in free-standing ambulatory surgery centers (ASCs). METHODS: We examined ASC-closed claims data between 2007 and 2014 from The Doctors Company, a medical malpractice insurer. Findings were coded using the Comprehensive Risk Intelligence Tool developed by CRICO Strategies. We compared coded data from ASC claims with hospital operating room (HOR) claims, in terms of injury severity category, nature of injury, nature of allegation, contributing factors identified, and contributing comorbidities and claim value. RESULTS: Ambulatory surgery center claims were more likely to be classified as medium severity than HOR claims, more likely to involve dental damage or pain than HOR claims, but less likely to involve death or respiratory or cardiac arrest. Technical performance was the most common contributing factor: 47% of ASCs and 48% of HORs. Only 7% of allegations relating to technical performance were judged to be a direct result of poor technical performance. The most common anesthesia procedures resulting in ASC claims were injection of anesthesia into a peripheral nerve (34%) and intubation (29%). Obesity was the most common contributing comorbidity in both settings. Mean closed claim value was significantly lower for ASC than HOR claims, averaging US $87,888 versus $107,325. CONCLUSIONS: Analysis of ASC and HOR claims demonstrates significant differences and several common sources of liability. These include improving strategies for thorough screening, preoperative assessment and risk stratifying of patients, incorporating routine dental and airway assessment and documentation, diagnosing and treating perioperative pain adequately, and improving the efficacy of communication between patients and care providers. PMID- 29189440 TI - Patient Safety Activity Under the Social Insurance Medical Fee Schedule in Japan: An Overview of the 2010 Nationwide Survey. AB - OBJECTIVES: Little is known about patient safety performance under the social insurance medical fee schedule in Japan. The Health Ministry in Japan introduced the preferential patient safety countermeasure fee (PPSCF) to promote patient safety in 2006 and revised the PPSCF system in 2010. This study aims to address the patient safety performance status at hospitals implementing the PPSCF. METHODS: A nationwide questionnaire survey targeting 2674 hospitals with the PPSCF was performed in 2010 to 2011. The 627 participant hospitals were divided into the following three groups: 178 hospitals implementing PPSCF 1 with 400 beds or more (group A), 286 hospitals implementing PPSCF 1 with 399 beds or fewer (group B), and 163 hospitals implementing PPSCF 2 (group C). RESULTS: The mean numbers (standard errors) of patient safety managers were 1.45 (0.07) in group A, 1.12 (0.04) in group B, and 0.37 (0.12) in group C (P < 0.001). The participation number and rates of all staff for the patient safety seminar were 1721 (167) and 1.64 (0.10) in group A, 580 (26) and 1.94 (0.09) in group B, and 349 (31) and 1.98 (0.17) in group C (P < 0.001, P = 0.105).These results can be explained because hospitals with PPSCF 1 (groups A and B) must assign at least one full time patient safety manager, whereas hospitals with PPSCF 2 (group C) are not required to do so. Patient safety performance at hospitals with PPSCF 1 was more active than that at hospitals with PPSCF 2. However, when the values were converted to per capita or per 100 beds, there were no differences across the three groups. CONCLUSIONS: The PPSCF encourages hospitals to perform actions for patient safety by providing incentives under the social insurance medical fee schedule in Japan.

PMID- 29189442 TI - Effect of postoperative radiotherapy on outcome in resectable stage IIIA-N2 non small-cell lung cancer: an updated meta-analysis. AB - BACKGROUND: In a previous meta-analysis-based modeling study, it was hypothesized that modern postoperative radiotherapy (PORT) may improve both local recurrence and overall survival (OS) in stage IIIA-N2 non-small-cell lung cancer (NSCLC). There were only four single-arm trials with a total of 357 patients. As other trials have provided new and controversial data, we performed this updated meta analysis to test the hypothesis. PATIENTS AND METHODS: Systematic reviews in Medline, Cochrane, and Science Direct up to December 2015 identified publications exploring the efficacy of PORT in resectable stage IIIA-N2 NSCLC. RESULTS: Overall, 16 trials comprising 3278 patients were included. There was a significant benefit in favor of PORT regarding OS [hazard ratio (HR): 0.73, 95% confidence interval (CI): 0.58-0.92, P=0.008; absolute benefit at 5 years=8%], disease-free survival (HR: 0.70, 95% CI: 0.60-0.83, P<0.0001), and locoregional recurrence-free survival (HR: 0.37, 95% CI: 0.24-0.58, P<0.0001). Restriction of the analysis to trials with induction and/or adjuvant chemotherapy led to similar results. PORT significantly decreased the risk of local recurrence (risk ratio: 0.64, 95% CI: 0.50-0.82, P=0.0006) and DM (risk ratio: 0.74, 95% CI: 0.62-0.88, P=0.0005), and the absolute risk differences were 13 and 14%, respectively. CONCLUSION: The addition of PORT, with or without chemotherapy, significantly improves local control and survival in patients with resectable stage IIIA-N2 NSCLC.

AB - PURPOSE: The aim of this study was to analyse the positive predictive value (PPV) of post-therapy fluorine-18-fluorodeoxyglucose (F-FDG) PET/CT performed for response or recurrence evaluation in patients with non-Hodgkin's lymphoma (NHL) and to appraise the diagnostic utility of F-FDG PET/CT-guided biopsy in this setting. PATIENTS AND METHODS: A total of 17 patients with NHL showing F-FDG avid lesions in F-FDG PET/CT performed for response or recurrence assessment underwent F-FDG PET/CT-guided biopsy using automated robotic biopsy arm needle navigation technique. The objectives were analysed in reference to histopathology. RESULTS: In all, 15 of the 17 (88.5%) procedures yielded adequate representative tissue samples. Nine out of 15 lesions were positive for residual disease and the remaining revealed benign findings on histopathology. One patient with inconclusive biopsy underwent surgical resection and histopathology confirmed the presence of residual disease. PPV of theF-FDG PET/CT was observed to be 62.5% (10/16). CONCLUSION: F-FDG PET/CT for response evaluation in NHL possesses a low PPV and hence warrants histopathological correlation when F-FDG PET/CT findings influence management decision. Diagnostic yield of F-FDG PET/CT-guided biopsy is high and has the potential to reduce sampling errors. PMID- 29189444 TI - The clinical value of PET and PET/CT in the diagnosis and management of suspected cervical cancer recurrence. AB - The aim of this study was to evaluate the clinical value of PET and PET/CT in suspected recurrent cervical cancer. The recurrence of cervical cancer has a poor prognosis. Earlier intervention would lead to a better prognosis. PET and PET/CT were promising in early diagnosis of recurrence because they could detect the biological and molecular changes before the anatomical size changes occurred. However, few data concerning the clinical effect of PET and PET/CT were available. The database for PET (or positron emission tomography or FDG or fluorodeoxyglucose) AND cervical cancer (or cervical tumor or cervical neoplasm or cervical carcinoma) AND recurrence or relapse was searched. The diagnostic value of PET or PET/CT was evaluated in both person-based and region-based analyses. Seventeen studies with 707 cases were included in the meta-analysis. For patients who were suspected of cervical cancer recurrence, the pooled sensitivity of PET and PET/CT was 0.97 (0.95-0.99). For patients who were suspected of relapse owing to elevated squamous cell carcinoma antigen, the pooled sensitivity was 0.99 (0.93-1.00). Moreover, the region-based diagnostic value in lung, mediastinum, liver/spleen, inguinal lymph node, supraclavicular lymph node, and para-aortic lymph node was high, from which we can see that PET and PET/CT had a favorable diagnostic value on distant metastasis. In addition, 57% of the therapeutic plans were modified owing to PET and PET/CT. PET and PET/CT are valuable tools in suspected recurrence of cervical cancer and provide valuable information for treatment decisions.

AB - School counselors are uniquely poised to influence career development among middle and high school students interested in nursing. This study examined 204 school counselors' perceptions about nursing and secondary educational preparation. Despite national and local efforts to increase enrollment in baccalaureate and higher nursing programs, counselors remain unaware of the need for increased education in nursing. Nurse educators need to align with school counselors to adequately prepare students interested in nursing as a health career.

PMID- 29189448 TI - Tumor Boost Using External Beam Radiation in Cervical Cancer Patients Unable to Receive Intracavitary Brachytherapy: Outcome From a Multicenter Retrospective Study (Korean Radiation Oncology Group 1419). AB - PURPOSE: We conducted this study to evaluate the outcomes of external-beam radiotherapy tumor boost (EBRT-B) in cervical cancer patients who could not receive intracavitary brachytherapy. METHODS: A total of 11 hospitals provided the data of patients who received EBRT-B during the period from January 2005 through October 2012. RESULTS: A total of 75 patients were included. The median radiotherapy dose was 46 Gy (range, 40-54 Gy) for whole pelvis and 24 Gy (range, 9-35 Gy) for EBRT-B. Initial tumor responses assessed at 2 to 6 months after radiotherapy were as follows: 46 with complete response, 22 with partial response, 2 with stable disease, and 3 with progressive disease. After a median follow-up time of 33 months, 30 patients (40.0%) showed disease progression including 21 (28.0%) with local progression. The 5-year local failure-free survival rate was 70.0%. Achieving complete response at the first follow-up visit and an overall treatment time of 53 days or less were significantly related to favorable local failure-free survival. The rate of grade 3 or higher toxicity was 2.6%. CONCLUSIONS: Approximately 70% of patients had local tumor control after curative radiotherapy using EBRT-B. Early tumor response and overall treatment time of 53 days or less were closely associated with favorable local control. PMID- 29189450 TI - Letters. PMID- 29189449 TI - Preoperative Serum Thymidine Kinase Activity as Novel Monitoring, Prognostic, and Predictive Biomarker in Pancreatic Cancer. AB - OBJECTIVE: The aim of the study was to investigate serum thymidine kinase 1 (S TK) activity as a diagnostic and prognostic marker for patients with pancreatic ductal adenocarcinoma (PDAC). METHODS: Using the sensitive TK activity assay DiviTum, preoperative serum samples from 404 PDAC, 28 chronic pancreatitis, and 25 autoimmune pancreatitis patients and 83 healthy volunteers were analyzed. The preoperative S-TK activities of 54 PDAC patients who received neoadjuvant therapy (nTx) were also compared with those of 258 PDAC patients who did not receive nTx. RESULTS: The preoperative S-TK activities of PDAC patients were significantly higher and discriminatory from autoimmune and chronic pancreatitis patients and control groups. The S-TK activity in PDAC patients was associated with overall survival. Patients with S-TK activity of less than 80 Du (DiviTum units)/L demonstrated median survival of 20.3 months with an estimated 18.0% 5-year survival rate; for S-TK activity of 80 Du/L or greater, median survival was 15.1 months with a 6.8% 5-year survival rate. For early-stage PDAC, these differences were even more pronounced. The S-TK activity in the nTx group was significantly higher than that in the group not receiving nTx. CONCLUSIONS: Pancreatic ductal adenocarcinomas reveal a significant increase in S-TK activity, which is associated with overall survival, especially in early tumor stages. Serum thymidine kinase 1 activity may be a useful parameter for monitoring nTx efficacy. PMID- 29189452 TI - Responding to parents who refuse childhood immunizations.

PMID- 29189467 TI - Student Perceptions of Clinical Instructor Characteristics Affecting Clinical Experiences. AB - AIM: The purpose of this study was to explore and describe students' perceptions of clinical instructor characteristics that affect their clinical experiences. BACKGROUND: Clinical instructors can have a profound impact on student clinical experiences, yet little is known about what clinical instructor characteristics promote and hinder quality clinical experiences from the student perspective. METHOD: A multisite prospective, descriptive exploratory design was used. RESULTS: Students ranked instructor knowledge and support as the highest desirable characteristics, followed by patience, creating challenges, enthusiasm, and organization. Emerging themes from the content analysis revealed that the ability of the instructor to convey knowledge, demonstrate professionalism, and exhibit enthusiasm and caring were key characteristics that influence the clinical experience. CONCLUSION: Nurse educators can use the results of this study to target hiring and placing of desired characteristics of clinical instructors and to support mentoring programs that promote clinical teaching excellence. PMID- 29189468 TI - Association of diastolic blood pressure with cardiovascular events in older people varies upon cardiovascular history. AB - BACKGROUND: In older age, a low DBP has been associated with increased risk of cardiovascular events, especially in frail older people. We tested the hypothesis that low DBP is associated with a high risk of cardiovascular events in people with a previous history of cardiovascular disease, as a proxy of vascular impairment. METHODS: We included 5804 participants (mean age 75 years) from the PROspective Study of Pravastatin in the Elderly at Risk (PROSPER) who as part of the trial were intensively monitored for an average period of 3.2 years. DBP was categorized in low (<70 mmHg), normal (70-90 mmHg) or high (>90 mmHg). Cox proportional hazards analyses were used to estimate hazard ratio with 95% confidence intervals (CI); analyses were stratified for cardiovascular history. RESULTS: Participants with low DBP had a 1.24-fold (1.04; 1.49) increased risk of cardiovascular events compared with those with normal DBP. After further adjusting for cardiovascular factors, this association attenuated to 1.05 (0.86; 1.28). A previous history of cardiovascular disease significantly modified the relation between DBP and risk of cardiovascular events (P-interaction 0.042). In participants without a history of cardiovascular disease, DBP was marginally significantly associated with an increased event risk (hazard ratio (95% CI) per 10 mmHg increase in DBP 1.08 (0.99; 1.18), P value = 0.07), whereas in participants with a history of cardiovascular disease, higher DBP was associated with a decreased risk of cardiovascular events (hazard ratio (95% CI) per 10 mmHg increase in DBP 0.92 (0.85; 0.99, P value = 0.018). These risk estimates were independent of potential confounders, including classical cardiovascular risk factors. CONCLUSION: The association of DBP with cardiovascular events in older people varies upon their previous history, showing that in participants with preexisting cardiovascular diseases, a higher DBP associates with a decreased risk of future cardiovascular events. PMID- 29189470 TI - Examining the Likelihood of Experiencing Productivity Loss and Receiving Social Security Disability Income Following the Onset of Chronic Disease. AB - OBJECTIVE: The aim of the study was to examine the likelihood of reporting productivity loss and receiving social security disability (SSD) income following a chronic health condition diagnosis using a longitudinal panel design. METHODS: Using the Panel Study of Income Dynamics, logistic regression analyses were conducted to estimate the likelihood of reporting productivity loss or receiving SSD following the diagnosis of arthritis, cancer, psychological problems, or heart conditions. Respondents reporting a new diagnosis of a condition were matched with five similarly aged respondents not reporting a diagnosis. RESULTS: For all conditions except cancer, the odds of reporting productivity loss and receiving SSD increased at both the wave where the condition was first reported and 2 years after for respondents reporting a condition compared with those not reporting a condition. CONCLUSIONS: The onset of chronic disease increases the likelihood of experiencing productivity loss and receiving SSD. PMID- 29189469 TI - Social Relations at Work and Incident Dementia: 29-Years' Follow-Up of the Copenhagen Male Study. AB - OBJECTIVE: We investigated whether social relations at work were associated with incident dementia in old age. METHODS: One thousand five hundred seventy-two occupationally active men from the Copenhagen Male Study Cohort were followed from 1986 to 2014. Participants underwent a clinical examination at baseline and answered questionnaires on whether they (1) had possibilities to be in contact with coworkers, (2) could get along with coworkers, and (3) were satisfied with supervisor. Poisson regression was used to estimate incidence rate ratios (IRR). RESULTS: Two hundred forty five (15.6%) men were diagnosed with dementia during an average of 15.8 years of follow-up. After adjusting for potential confounders, limited contact with coworkers was associated with a higher risk of dementia (IRR = 2.49, 95% confidence interval [CI] 1.14 to 5.44), but the other two measures were not. CONCLUSIONS: Our data partially support that social relations at work are associated with incident dementia. PMID- 29189471 TI - A Novel Approach to Reducing Workers Compensation Costs in a Multicenter Hospital System. AB - OBJECTIVE: To evaluate the efficacy of an injury prevention and monitoring program implemented by athletic trainers to reduce workers compensation costs in a hospital system with multiple centers and locations. METHODS: A retrospective analysis of workers compensation claims (ie, lost days, light days, and incurred costs) was performed to compare injury data from 2 years before to 2 years after the start of the program. RESULTS: The program significantly reduced the organization's incurred costs by 46.7% (P = 0.031) and light days by 44% (P = 0.022). Lost days were found to decrease by 37%, however, this decrease was not statistically significant (P = 0.078). CONCLUSIONS: Athletic trainers, using their knowledge of anatomy, biomechanics, ergonomics, injury management, and rehabilitation, can effectively prevent and reduce workers compensation costs in a multicenter hospital system. PMID- 29189472 TI - SIRT2 and Akt mediate NAD+-induced and NADH-induced increases in the intracellular ATP levels of BV2 microglia under basal conditions. AB - NAD replenishment can restore ATP levels and rescue premature aging in Cockayne syndrome mice. However, there has been no mechanistic study regarding the effects of NAD and NADH on intracellular ATP levels under basal conditions. In our current study, we used BV2 microglia to test our hypothesis that NAD and NADH can increase intracellular ATP levels under basal conditions. We found that both NAD and NADH significantly increased the intracellular ATP levels of BV2 microglia, which were attenuated by SIRT2 siRNA, the SIRT2 inhibitor AGK2, and the phosphatidylinositol 3-kinase/Akt inhibitor LY294002. Our study has also suggested that SIRT2 mediates the NAD-induced and NADH-induced increase in Akt phosphorylation in BV2 microglia. Collectively, our study has suggested that SIRT2 mediates both NAD-induced and NADH-induced increases in the intracellular ATP levels of BV2 microglia by modulating Akt phosphorylation. PMID- 29189473 TI - The anger expression trait affects conflict monitor: a Go/No-go event-related potential study. AB - The Anger-Out and Anger-In is the emotional expression of anger in two main ways. To explore the time course of inhibitory control in individuals with different anger expression trait, we recorded and analyzed event-related potential data relevant to the Go/No-go task. Although the No-go effect of P3 closely related to the actual inhibition of the motor system was similar between two groups, the No go effect of N2 related to conflict monitoring was smaller in the Anger-In than that in the Anger-Out group. These data suggest the reduced early stage of inhibitory processes in Anger-In individuals, implicating the dysfunction of conflict monitoring and providing new electrophysiological evidence for the theory of anger expression. PMID- 29189474 TI - Pediatric ACL Reconstruction and Return to the Operating Room: Revision is Less Than Half of the Story. AB - BACKGROUND: Although there are several causes of unplanned return to the operating room (RTOR) following pediatric anterior cruciate ligament (ACL) reconstruction (ACLR), prior outcomes studies focus primarily on the risk of graft failure. We sought to comprehensively describe indications for RTOR in pediatric primary ACLR patients, estimate associated rates of RTOR, and assess the impact of concomitant meniscal procedures on these rates. METHODS: This retrospective cohort study considered patients who underwent primary ACLR at an urban, pediatric tertiary care hospital between 2013 and 2015. Cohorts were defined based on the presence or absence of a concomitant surgical meniscal procedure with the index ACLR. The primary outcome was RTOR for an indication pertaining to ACLR or a potential predilection for knee injury. Cases of RTOR were cataloged and classified according to indication. Survival analyses were performed using the Kaplan-Meier estimation and competing-risks regression. Comparisons of any-cause RTOR rates were done using log-rank tests. RESULTS: After exclusion criteria were applied, 419 subjects were analyzed. RTOR indications were organized into 5 categories. The overall rate for any RTOR by 3 years after surgery was 16.5%. Graft failure and contralateral ACL tear were the most common indications for RTOR, with predicted rates of 10.3% and 7.1%, respectively. ACL graft failure accounted for less than half of RTOR cases cataloged. Patients who had a concomitant meniscus procedure had lower rates of RTOR. CONCLUSIONS: Approximately 1 in 6 pediatric ACLR patients underwent >=1 repeat surgery within 3 postoperative years for indications ranging from wound breakdown to contralateral ACL rupture. While previous studies revealed high rates of complication after pediatric ACLR due primarily to graft failure, we found that re-tear is responsible for less than half of the 3-year RTOR risk. As almost half of re-tears in our sample occurred before clearance to return to full activities, we suspect that the high rate of complication is largely attributable to pediatric patients' high activity levels and difficulties adhering to postoperative restrictions. Early treatment of meniscus pathology may reduce rates of RTOR. LEVEL OF EVIDENCE: Level III-therapeutic. PMID- 29189475 TI - Responding to Financial Challenges by Reducing Costs and Improving Quality. PMID- 29189476 TI - Pursuit of Value Drives Strategy to Improve Operations and Outcomes. AB - The future of American healthcare remains cloudy, with the shifting contours of regulatory and fiscal reform still being shaped. Providers are beset by many challenges that vary but often include state and federal healthcare funding decisions that are antithetical to the interests of patients and aging populations. Regional public health crises and rapidly evolving relationships with third-party payers complicate matters even further.Yale New Haven Health System decided to pursue value as its overriding strategy for navigating the uncertainty in healthcare that is likely to persist for years to come. Many, if not most, of the challenges we face at Yale New Haven Health are shared by health systems across the country; the operational concepts that drive our strategy likely will be familiar. The differentiator is the execution: At Yale New Haven Health, infusing our organization with a culture of high reliability, as well as adopting the practice of clinical redesign, has yielded concrete enhancements in patient care, operational resilience, and financial sustainability. Clinical redesign saved Yale New Haven Health nearly $25 million in direct costs in one year alone. PMID- 29189477 TI - Remaining Financially Viable in a Time of Healthcare Transition. AB - In an unstable healthcare environment, Western Maryland Health System has been demonstrating stability. We have responded to the many challenges that hospitals face and managed to thrive in the new, value-based world.We made the transition to value-based payment and care delivery models through innovations in Maryland's payment system. In 2010, we recognized that becoming a demonstration project for value-based care would benefit our health system as we dealt with an aging and shrinking regional population. By moving care away from the acute setting to other settings across the care continuum, we now treat patients in the most appropriate setting (e.g., the home, physician office, clinic, and even senior centers, churches, and homeless shelters).As we have transitioned care, we have also transitioned our workforce. With fewer acute care patients, we need fewer staff members at the bedside. Many of our staff have shifted to delivering care in pre- and post-acute care settings.To improve our financial performance, we formed an alliance of three health systems. This new alliance has found increased savings by consolidating services, managing regionwide population health initiatives, and benchmarking clinical quality through best practices. Through the alliance, each individual health system is stronger and well augmented by the savings that it could not achieve separately.The transition has not been easy, but we have shown that it is achievable. We have identified a number of solutions to reduce costs and generate savings while enhancing quality and patient safety. These solutions may present a pathway to success for other organizations seeking to move to value-based care delivery and new payment models.

PMID- 29189481 TI - Incidental Cardiac Findings in Non-Electrocardiogram-gated Thoracic Computed Tomography of Intensive Care Unit Patients: Assessment of Prevalence and Underreporting. AB - PURPOSE: Cardiac findings frequently remain unreported on non-electrocardiogram (ECG)-gated computed tomography (CT). Although the clinical relevance of such findings may be limited in a general patient population, they may have significant impact in intensive care patients. Thus, the purpose of this study was to evaluate the prevalence, underreporting, and clinical relevance of incidental cardiac findings in intensive care unit (ICU) patients. MATERIALS AND METHODS: Non-ECG-gated chest CT examinations of ICU patients were retrospectively analyzed for incidental cardiac findings. The findings were classified into 3 categories (A to C): category A findings, which carry potential for risk to life; category B findings, which have a potential for significant morbidity; category C findings, which have a possible effect on prognosis. RESULTS: A total of 500 patients who underwent non-ECG-gated thoracic CT examinations were included. Of the 500 patients, 403 presented with 1443 cardiac findings. Of all cardiac findings, 37% were described in the initial written report. Sixty category A findings were detected, of which 48% were not mentioned in the report. Six hundred forty category B findings were detected, of which 77% were not described in the report. The remaining 743 findings were classified as category C, 55% of which were not reported in the report. CONCLUSIONS: The prevalence as well as the rate of underreporting of incidental cardiac findings in non-ECG-gated chest CT of ICU patients is very high. The results of this study underscore the importance of dedicated training for assessment of cardiac structures and conditions, which may be detected on non-ECG-gated chest CT. PMID- 29189482 TI - Analysis of Biomarkers Within the Initial 2 Years Posttransplant and 5-Year Kidney Transplant Outcomes: Results From Clinical Trials in Organ Transplantation 17. AB - BACKGROUND: An early posttransplant biomarker/surrogate marker for kidney allograft loss has the potential to guide targeted interventions. Previously published findings, including results from the Clinical Trials in Organ Transplantation (CTOT)-01 study, showed that elevated urinary chemokine CXCL9 levels and elevated frequencies of donor-reactive interferon gamma (IFNgamma) producing T cells by enzyme-linked immunosorbent spot (ELISPOT) assay associated with acute cellular rejection within the first year and with lower 1-year posttransplant estimated glomerular filtration rate (eGFR). How well these biomarkers correlate with late outcomes, including graft loss, is unclear. METHODS: In CTOT-17, we obtained 5-year outcomes in the CTOT-01 cohort and correlated them with (a) biomarker results and (b) changes in eGFR (Chronic Kidney Disease Epidemiology Collaboration formula) over the initial 2 years posttransplant using univariable analysis and multivariable logistic regression. RESULTS: Graft loss occurred in 14 (7.6%) of 184 subjects 2 to 5 years posttransplant. Neither IFNgamma ELISPOTs nor urinary CXCL9 were informative. In contrast, a 40% or greater decline in eGFR from 6 months to 2 years posttransplant independently correlated with 13-fold odds of 5-year graft loss (adjusted odds ratio, 13.1; 95% confidence interval, 3.0-56.6), a result that was validated in the independent Genomics of Chronic Allograft Rejection cohort (n = 165; adjusted odds ratio, 11.2). CONCLUSIONS: We conclude that although pretransplant and early posttransplant ELISPOT and chemokine measurements associate with outcomes within 2 years posttransplant, changes in eGFR between 3 or 6 months and 24 months are better surrogates for 5-year outcomes, including graft loss. PMID- 29189483 TI - Heme Oxygenase 1 Attenuates Hypoxia-Reoxygenation Injury in Mice Liver Sinusoidal Endothelial Cells. AB - BACKGROUND: Heme oxygenase 1 (HO-1), a heat shock protein, can be involved in the resolution of inflammation by modulating cytokine expression and apoptotic cell death. Based on recent evidence that liver sinusoidal endothelial cells (LSECs) is the critical target in early period of liver ischemia-reperfusion injury (IRI), this study aims to clarify whether overexpression of HO-1 gene provides a protective effect on mice LSECs. METHODS: LSECs were transfected with adenovirus vectors encoding mice HO-1 gene (Ad-HO-1) or green fluorescent protein. Controls were not infected with any vector. LSECs were then treated with hypoxic or normoxic culture. We used low serum culture medium and hypoxia-reoxygenation (H R) conditions to cause IRI in vitro. The transfection efficiency of HO-1 gene in LSECs, after 48 hours of transfection, and the effect of HO-1 on the model of H-R injury in LSECs were observed. RESULTS: Transfection of LSECs with Ad-HO-1 was at an optimal dose (multiplicity of infection = 80) to markedly express HO-1 mRNA and protein. Groups of overexpressed HO-1 showed lower levels of inflammatory factor mediators IL-6 and TNF-alpha. Survival rate of the cells after H-R injury was higher and attributed to overexpressed HO-1. In contrast, the control adenovirus expressing the enhanced green fluorescent protein failed to induce HO 1 expression and stimulated cell apoptosis. HO-1 expression was downregulated in all H-R groups compared with normoxia groups, which may be related to the disruption of the LSEC structure. CONCLUSIONS: Upregulation of HO-1 can attenuate H-R injury in LSECs by inhibiting proinflammatory cytokine release and diminishing apoptotic cell death. PMID- 29189484 TI - Comparison of BQ123, Epoprostenol, and Verapamil as Vasodilators During Normothermic Ex Vivo Liver Machine Perfusion. AB - BACKGROUND: The optimal vasodilator to avoid hepatic artery vasospasm during normothermic ex vivo liver perfusion (NEVLP) is yet to be determined. We compared safety and efficacy of BQ123 (endothelin1 antagonist), epoprostenol (prostacyclin analogue), and verapamil (calcium channel antagonist). METHODS: Livers from porcine heart beating donors were perfused for 3 hours and transplanted into recipient pigs. Four groups were compared: group 1, livers perfused with a dose of 1.25 mg of BQ123 at baseline and at 2 hours of perfusion; group 2, epoprostenol at a continuous infusion of 4 mg/h; group 3, verapamil 2.5 mg at baseline and at 2 hours of perfusion; group 4, no vasodilator used during ex vivo perfusion. Liver injury and function were assessed during perfusion, and daily posttransplantation until postoperative day (POD) 3. All groups were compared with a cold storage group for postoperative graft function. RESULTS: Hepatic artery flow during NEVLP was significantly higher in BQ123 compared with verapamil, epoprostenol, and no vasodilator-treated livers. Aspartate aminotransferase levels were significantly lower with BQ123 and verapamil compared with epoprostenol and control group during perfusion. Peak aspartate aminotransferase levels were lower in pigs receiving BQ123 and verapamil perfused grafts compared with epoprostenol and control group. International Normalized Ratio, alkaline phosphatase, and total bilirubin levels were lower in the BQ123 and verapamil groups compared to epoprostenol group. Cold storage group had increased markers of ischemia reperfusion injury and slower graft function recovery compared to machine perfused grafts. CONCLUSION: The use of BQ123, epoprostenol, and verapamil during NEVLP is safe. Livers perfused with BQ123 and verapamil have higher hepatic artery flow and reduced hepatocyte injury during perfusion compared with epoprostenol. Hepatic artery flow is significantly reduced in the absence of vasodilators during NEVLP. PMID- 29189485 TI - Myeloid-Derived Suppressor Cells and Their Potential Application in Transplantation. AB - Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of immunosuppressive cells of the myeloid lineage upregulated by mediators of inflammation, such as IL-2, granulocyte colony-stimulating factor, and S100A8/A9. These cells have been studied extensively by tumor biologists. Because of their robust immunosuppressive potential, MDSCs have stirred recent interest among transplant immunologists as well. MDSCs inhibit T-cell responses through, among other mechanisms, the activity of arginase-1 and inducible nitric oxide synthase, and the expansion of T regulatory cells. In the context of transplantation, MDSCs have been studied in several animal models, and to a lesser degree in humans. Here, we will review the immunosuppressive qualities of this important cell type and discuss the relevant studies of MDSCs in transplantation. It may be possible to exploit the immunosuppressive capacity of MDSCs for the benefit of transplant patients. PMID- 29189486 TI - Association of Cardiac Abnormalities to the Frail Phenotype in Cirrhotic Patients on the Waitlist: From the Functional Assessment in Liver Transplantation Study. AB - BACKGROUND: Frailty is a syndrome of decreased physiologic reserve that results from compromise of multiple physiologic systems including cardiovascular system. We aimed to determine the association between the frail phenotype and cardiac abnormalities in liver transplant (LT) candidates through evaluation of transthoracic echocardiography (TTE) indices. METHODS: Included were consecutive outpatients listed for LT who underwent a frailty assessment from January 1, 2014, to June 30, 2016 (using the Liver Frailty Index) and a 2 dimensional/Doppler TTE examination. Patients were categorized as robust, intermediate frail, or frail by the Liver Frailty Index based on scores of less than 3.2, between 3.2 and 4.5, or 4.5 or greater. Linear regression assessed associations between the Liver Frailty Index and TTE indices. RESULTS: Of 335 patients, 19% were robust, 65% intermediate frail, and 16% frail. TTE indices of left atrial (LA) dilatation differed significantly by frailty status: median LA dimension (P = 0.03), LA volume index (LAVI mL/m; P < 0.001) and %LAVI > 34 mL/m (P = 0.001). In linear regression adjusted for age, sex, hypertension, and diabetes, the Liver Frailty Index was positively associated with LA dimension (coeff, 0.20; 95% confidence interval [CI], 0.07-0.34), LAVI mL/m (coeff, 0.01; 95% CI, 0.005-0.02), ejection fraction (coeff, 1.59; 95% CI, 0.32-2.85), and pulmonary artery systolic pressure (coeff, 0.01; 95% CI, 0.003-0.02), and negatively associated with LV hypertrophy (coeff, -0.22; 95% CI, -0.37 to -0.06). CONCLUSIONS: In LT candidates, frailty is associated with cardiac structural and functional changes, independent of known risk factors. Our study provides evidence to support that measures of frailty in cirrhotic patients encompass abnormalities of the cardiovascular system and may inform assessments of cardiovascular reserve in this population. PMID- 29189488 TI - Interim 18F-FDG PET/CT and BCL2 for predicting the prognosis of patients with diffuse large B-cell lymphoma in the rituximab era. AB - OBJECTIVE: In this study, we investigated the prognostic role of interim fluorine 18-fluorodeoxyglucose PET/computed tomography (I-PET/CT) and BCL2 in diffuse large B-cell lymphoma (DLBCL) patients treated with rituximab-containing chemotherapy. MATERIALS AND METHODS: A total of 106 patients with newly diagnosed DLBCL underwent PET/CT scans at baseline and a subsequent I-PET/CT after the fourth cycle of chemotherapy. I-PET/CT was analyzed using the Deauville five point score. The prognostic significance of I-PET/CT and BCL2 was evaluated by predicting progression-free survival (PFS) and overall survival (OS). RESULTS: With a median follow-up of 25 months, the 2-year PFS and OS were 78 and 95% in the I-PET/CT-negative group and 33 and 57% in the I-PET/CT-positive group (P<0.001). Patients with BCL2 positivity showed a shorter PFS than the BCL2 negative patients (P=0.002), but not in OS (P=0.068). In multivariate analysis, I PET/CT and BCL2 were independent variables in assessing the outcome of PFS. I PET/CT was also an independent factor for OS. Irrespective of the results of BCL2, patients with I-PET/CT positivity had a significant inferior outcome than the I-PET/CT-negative patients. In the I-PET/CT-negative group, patients with BCL2 positivity had a significantly shorter PFS than the BCL2-negative patients (P=0.005). CONCLUSION: I-PET/CT and BCL2 were two significant independent indicators of outcome for patients with DLBCL in the rituximab era. I-PET/CT was much better than BCL2 for patient stratification. BCL2 showed its supplementary role for further patient stratification when I-PET/CT was negative. PMID- 29189487 TI - Rituximab and Therapeutic Plasma Exchange in Recurrent Focal Segmental Glomerulosclerosis Postkidney Transplantation. AB - BACKGROUND: Focal segmental glomerulosclerosis (FSGS) is a common cause of end stage renal disease with a high rate of recurrence after kidney transplantation. Several factors, such as white race, rapid progression, and previous allograft failure due to recurrence, were found to be risks of recurrence. Data are limited on the benefits of rituximab and/or therapeutic plasma exchange (TPE) in preventing recurrence. In this study, we sought to assess the efficacy of rituximab and TPE for the prevention and treatment of recurrent FSGS after kidney transplantation. METHODS: We enrolled 66 patients with FSGS in this prospective observational study and followed their outcomes. Patients with high risk for recurrence received preventative therapy with TPE and/or rituximab. RESULTS: Twenty-three (62%) of the 37 patients who received preventative therapy developed recurrence compared with 14 (51%) recurrences of the 27 patients who did not receive any therapy (P = 0.21). There was a trend for less relapse when rituximab was used as a therapy for recurrent FSGS (6/22 vs 9/18, P = 0.066). We used a clinical score of 5 values to assess the prediction of FSGS recurrence. A score of 3 or more had a predictive receiver operating characteristic curve of 0.72. Treatment with TPE and/or rituximab resulted in better allograft survival than historical studies. Allograft failure because of recurrent FSGS occurred in only 6 (9%) patients. CONCLUSIONS: Preventative therapies do not decrease the recurrence rate of recurrent FSGS. However, prompt treatment of recurrence with these therapies may result in improved outcomes. PMID- 29189489 TI - Utility of whole-body (head-to-toe) PET/CT in the evaluation of melanoma and sarcoma patients. AB - OBJECTIVE: The aim of this study was to assess the added benefit of whole-body (head-to-toes) PET/CT versus routine 'eyes-to-thighs' PET/CT of melanoma and sarcoma patients. PATIENTS AND METHODS: We performed a retrospective review of consecutive whole-body PET/CT scans from January 2006 through December 2010 in patients with melanoma or sarcoma. PET abnormalities in the brain, distal thighs, and legs were recorded and clinical significance was assessed on the basis of pathology, imaging studies, and clinical follow-up. Patients with known primary lesions distal to the proximal femora were excluded as these patients would routinely undergo 'head-to-toe' PET/CT. RESULTS: We reviewed reports from 352 PET/CT examinations in 194 patients with melanoma and 75 PET/CT examinations in 44 patients with sarcoma. Melanoma: 13 patients had brain metastases on PET. In five of these patients, lesions were unknown, but all were in the setting of other metastatic disease. Twenty-seven patients had lower extremity metastases, all in the setting of other metastatic disease. No lower extremity metastases were found in the remaining 167 patients. Sarcoma: one patient had an isolated, unexpected brain metastasis. Six patients had leg metastases, but none were isolated. No lower extremity metastases were found in the remaining 38 patients. CONCLUSION: In patients with melanoma and sarcoma, inclusion of entire lower extremities adds little additional clinical value as detection of isolated, unexpected metastasis is rare. Brain imaging may add value as the presence of brain metastases alters clinical management. Overall, in patients with melanoma or sarcoma, whole-brain PET/CT imaging may be of value, but routine inclusion of the entire lower extremities adds little additional value. PMID- 29189490 TI - Excretion and whole-body retention of radium-223 dichloride administered for the treatment of bone metastases from castration resistant prostate cancer. AB - OBJECTIVE: The aim of the study was to determine the fraction of administered activity that was excreted and retained by a small cohort of patients who each received treatment with radium-223 dichloride (Ra). Ra is an alpha-emitting radionuclide that has been approved for use in the treatment of bone metastases that are secondary to castration resistant prostate cancer. PATIENTS AND METHODS: Six patients received two weight-based administrations of Ra 6 weeks apart. Activity excreted in the urine and faeces during the first 48 h following each treatment was assessed by direct counting of the excreta. During the same period the whole-body retention of Ra was also determined using a single probe counting system. The results of the excreta counting and the whole-body counting were compared to determine whether whole-body counting was a suitable surrogate for assessing excretion. Further whole-body retention counts were made at around 3, 4, 7 and 42 days following treatment. RESULTS: Patterns of excretion and retention of Ra varied significantly between patients, but were similar for each patient's pair of treatments. The cumulative maximum activity excreted in the initial 8-h period following the Ra administration was 2.6% that increased to 39% at 48 h. The median excreted activity at ~1 and 6 weeks after treatment was 70 and 86%, respectively. Skeletal retention of Ra at 6 weeks ranged from 11 to 60% of the administered activity. PMID- 29189491 TI - Project ECHO: A Telementoring Network Model for Continuing Professional Development. AB - INTRODUCTION: A major challenge with current systems of CME is the inability to translate the explosive growth in health care knowledge into daily practice. Project ECHO (Extension for Community Healthcare Outcomes) is a telementoring network designed for continuing professional development (CPD) and improving patient outcomes. The purpose of this article was to describe how the model has complied with recommendations from several authoritative reports about redesigning and enhancing CPD. METHODS: This model links primary care clinicians through a knowledge network with an interprofessional team of specialists from an academic medical center who provide telementoring and ongoing education enabling community clinicians to treat patients with a variety of complex conditions. Knowledge and skills are shared during weekly condition-specific videoconferences. RESULTS: The model exemplifies learning as described in the seven levels of CPD by Moore (participation, satisfaction, learning, competence, performance, patient, and community health). The model is also aligned with recommendations from four national reports intended to redesign knowledge transfer in improving health care. Efforts in learning sessions focus on information that is relevant to practice, focus on evidence, education methodology, tailoring of recommendations to individual needs and community resources, and interprofessionalism. DISCUSSION: Project ECHO serves as a telementoring network model of CPD that aligns with current best practice recommendations for CME. This transformative initiative has the potential to serve as a leading model for larger scale CPD, nationally and globally, to enhance access to care, improve quality, and reduce cost. PMID- 29189492 TI - The Prato Method: A Guide to the Application of Economic Evaluations in Health Professions Education Research. AB - The estimation of cost and value in health professions education should involve robust methodologies and decision tools. These methods and tools should be applied consistently and transparently, but more importantly, employed in the appropriate context depending on the availability of data, target estimates, and stakeholder focus. Best practice methodology and application of decision tools will allow for a clearer and more comprehensive understanding of the return on investment of health profession education interventions by shedding greater light on the full opportunity cost of providing programs and the value of such programs to learners and recipients of health care services more broadly. This article provides insight into the basic methods, decision tools, and key evaluation concepts that might be considered for the purpose of undertaking cost and value research in continuing education for health professionals. These methods and decision tools are based on consolidated discussions by the organizing delegates of the inaugural Symposium of the Society for Cost and Value of Health Professions Education, held in Prato, Italy, October 2015. In summary, the application of economic methods and tools used for analyzing health professions education is currently inconsistent. This article provides an overview and recommendations on the use of certain economic methods and tools when evaluating health profession education programs. It also provides a clear understanding of key evaluation concepts important for undertaking an economic review of a program. PMID- 29189493 TI - What Family Physicians Really Think of Maintenance of Certification Part II Activities. AB - INTRODUCTION: This study examines how improving curricular content and technical interface issues could make maintenance of certification activities more meaningful to American Board of Family Medicine diplomates completing Maintenance of Certification for Family Physicians (MC-FP) Program self-assessment modules (SAMs). METHODS: We used a sequential exploratory design to analyze quantitative and qualitative data from 320,500 surveys of family physicians who completed a SAM between January 2004 and April 2013. This included numeric rating scales and free text comments. Basic statistical rankings, template-based automated coding, and emergent coding were used to analyze SAM experience and identify thematic content. RESULTS: Across SAMs, numeric ratings were universally high and positive free text comments outnumbered negative comments two to one. When comparing feedback on the knowledge assessment and clinical simulation (CS) activities, SAMs were rated less favorably when the frequency of ideas identified by participants as most prevalent in one activity mismatched those identified as most prevalent in the companion activity. Participants were also critical of navigation issues, technical issues, and a lack of realness in the CS activity. DISCUSSION: Whether analyzed through quantitative data, qualitative data, or mixed methods, a large majority of participants rated their experience with SAMs highly. When individual SAMs were rated poorly, it seemed to be due to discordance in ideas emphasized between the knowledge assessment and CS components, or an opinion regarding the SAM topic that existed independent of the SAM process. PMID- 29189494 TI - Rethinking Remediation: A Model to Support the Detailed Diagnosis of Clinicians' Performance Problems and the Development of Effective Remediation Plans. AB - The successful remediation of clinicians demonstrating poor performance in the workplace is essential to ensure the provision of safe patient care. Clinicians may develop performance problems for numerous reasons, including health, personal factors, the workplace environment, or outdated knowledge/skills. Performance problems are often complex involving multifactorial issues, encompassing knowledge, skills, and professional behaviors. It is important that (where possible and appropriate) clinicians are supported through effective remediation to return them to safe clinical practice. A review of the literature demonstrated that research into remediation is in its infancy, with little known about the effectiveness of remediation programs currently. Current strategies for the development of remediation programs are mostly "intuitive"; a few draw upon established theories to inform their approach. Similarly, although it has been established that identification of the nature/scope of performance problems through assessment is an essential first step within remediation, the need for a more widespread "diagnosis" of why the problems exist is emerging. These reasons for poor performance, particularly in the context of experienced practicing clinicians, are likely to have an impact on the potential success of remediation and should be considered within the "diagnosis." A new model for diagnosing the performance problems of the clinicians has been developed, using behavioral change theories to explore known barriers to successful remediation, such as insight, motivation, attitude, self-efficacy, and the working environment, in addition to addressing known deficits regarding knowledge and skills. This novel approach is described in this article. An initial feasibility study has demonstrated the acceptability and practical implementation of our model. PMID- 29189495 TI - Lumbar Spine Anatomy in Women Sustaining Unintentional Dural Puncture During Labor Epidural Placement: A Descriptive Study Using Magnetic Resonance Imaging and Ultrasound. AB - BACKGROUND AND OBJECTIVES: Unintentional dural puncture is one of the most frequent complications of the epidural technique. One previous study suggested that atypical sonoanatomy of the ligamentum flavum/dura mater unit may be a risk factor for this complication. In this study, we describe the anatomy of the lumbar spine, assessed by magnetic resonance imaging (MRI) and ultrasound, in women sustaining unintentional dural puncture during epidural catheter placement for labor analgesia. METHODS: We approached women who sustained a recognized unintentional dural puncture. Following consent, technical aspects of the epidural catheter placement were documented. Postpartum MRI of the lumbar spine and bedside spinal ultrasound were performed. Ultrasound images of the ligamentum flavum/dura mater unit in the transverse view were classified as typical, atypical, or inconclusive. Magnetic resonance imaging images were reviewed by a neuroradiologist, who was blinded to the level of the puncture. RESULTS: We included 10 women with unintentional dural punctures in the study. In 5 of the 10 women, these dural punctures occurred despite epidural catheter insertion by experienced practitioners. These women had a mean body mass index of 28.5 kg/m (range, 24-38 kg/m). Two women suffered dural punctures twice. Ultrasound imaging in the paramedian view produced typical images in all patients. In the transverse view, 7 of 10 women showed atypical or inconclusive images, with atypical images seen at either L4/5 or L5/S1. Magnetic resonance imaging results revealed no anatomical abnormalities, with the exception of 1 woman who showed a ligamentum flavum gap away from the puncture site. CONCLUSIONS: Our results suggest that unintentional dural punctures occur in likely anatomically normal women. Furthermore, the transverse ultrasound views may fail to demonstrate typical ligamentum flavum/dura mater unit at the lower lumbar levels despite its confirmed presence by MRI. PMID- 29189496 TI - Artificial Neural Network: A Method for Prediction of Surgery-Related Pressure Injury in Cardiovascular Surgical Patients. AB - PURPOSE: The aim of this study was to build an artificial neural network (ANN) model for predicting surgery-related pressure injury (SRPI) in cardiovascular surgical patients. DESIGN: Prospective cohort study. SUBJECTS AND SETTING: One hundred forty-nine patients who had cardiovascular surgery were included in the study. This study was conducted in a 1000-bed teaching hospital in Eastern China where 250 to 350 cardiac surgeries are performed each year. METHODS: We performed a prospective cohort study among consecutive patients undergoing cardiovascular surgery between January and December 2015. The ANN model was built based on possible SRPI risk factors. The model performance was tested by a receiver operating characteristic curve and the C-index. A C-index from 0.5 to 0.7 is classified as having low accuracy, 0.7 to 0.9 as having moderate accuracy, and 0.9 to 1.0 as having high accuracy. We also compared the actual SRPI incidences based on the ANN stratification. RESULTS: Thirty-seven of 147 patients developed SRPIs, yielding an incidence rate of 24.8% (95% CI, 18.1-32.6). The C-index was 0.815, which showed the ANN model had a moderate prediction value for SRPI. According to the ANN model, the SRPI predicting incidence ranged from 6.4% to 67.7%. Surgery-related pressure injury incidences were significantly different among 3 risk groups stratified by the ANN (P < .05). CONCLUSION: We established an ANN model that provides moderate prediction of SRPI in patients undergoing cardiovascular surgical procedures. Identification and additional associated factors should be incorporated into the ANN model to increase its predictive ability.

PMID- 29189499 TI - Mind the Gap: Approaches to Addressing the Research-to-Practice, Practice-to Research Chasm. PMID- 29189500 TI - Innovative Methods for Designing Actionable Program Evaluation. AB - CONTEXT: For most programs, whether funded through governmental agencies or nongovernmental organizations, demonstrating the impact of implemented activities is vital to ensuring continued funding and support. OBJECTIVE: Program evaluation is a critical tool that serves the dual purpose of describing impact and identifying areas for program improvement. From a funder's perspective, describing the individual and collective impact of state-based programs can be challenging due to variations in strategies being implemented and types of data being collected. DESIGN: A case study was used to describe the actionable, mixed methods evaluation of the Core Violence and Injury Prevention Program (Core VIPP), including how the evaluation design and approach shifted to address evolving challenges faced by award recipients over time. Particular emphasis is given to innovative methods for collecting, analyzing, and disseminating data for key state and federal stakeholders. RESULTS: The results of the Core VIPP evaluation showed how this funding played a vital role in building injury and violence prevention capacity in state health departments, leading to a decrease in both intermediate and long-term outcomes. CONCLUSIONS: The lessons learned through the mixed-method evaluation of the Core VIPP informed the structure of the subsequent funding cycle (Core SVIPP) to include more prescriptive requirements for evidence-based implementation and a state support team structure for delivery of training and technical assistance. PMID- 29189501 TI - State Injury Programs' Response to the Opioid Epidemic: The Role of CDC's Core Violence and Injury Prevention Program. AB - The Centers for Disease Control and Prevention's (CDC's) Core Violence and Injury Prevention Program (Core) supports capacity of state violence and injury prevention programs to implement evidence-based interventions. Several Core funded states prioritized prescription drug overdose (PDO) and leveraged their systems to identify and respond to the epidemic before specific PDO prevention funding was available through CDC. This article describes activities employed by Core-funded states early in the epidemic. Four case examples illustrate states' approaches within the context of their systems and partners. While Core funding is not sufficient to support a comprehensive PDO prevention program, having Core in place at the beginning of the emerging epidemic had critical implications for identifying the problem and developing systems that were later expanded as additional resources became available. Important components included staffing support to bolster programmatic and epidemiological capacity; diverse and collaborative partnerships; and use of surveillance and evidence-informed best practices to prioritize decision-making. PMID- 29189503 TI - Indicators for Evaluating Community- and Societal-Level Risk and Protective Factors for Violence Prevention: Findings From a Review of the Literature. AB - Programs geared toward preventing violence before it occurs at the community and societal levels of the social ecology are particularly challenging to evaluate. These programs are often focused on impacting the antecedents (or risk and protective factors) to violence, making it difficult to determine program success when solely relying on measures of violence reduction. The goal of this literature review is to identify indicators to measure risk and protective factors for violence that are accessible and measured at the community level. Indicators of community- and societal-level risk and protective factors from 116 articles are identified. These indicators strengthen violence prevention researchers' and practitioners' ability to detect proximal effects of violence prevention programs, practices, and policies, and provide timely feedback on the impact of their work. Thus, opportunities exist for violence prevention researchers to further study the associations between various indicators and different violent outcomes and to inform practitioner, evaluator, and funder developed logic models that include indicators of relevant risk and protective factors for crosscutting violence prevention measures and outcomes. PMID- 29189504 TI - The Use of the Data-to-Action Framework in the Evaluation of CDC's DELTA FOCUS Program. AB - The Centers for Disease Control and Prevention's (CDC's) Domestic Violence Prevention Enhancements and Leadership Through Alliances, Focusing on Outcomes for Communities United with States (DELTA FOCUS) program is a 5-year cooperative agreement (2013-2018) funding 10 state domestic violence coalitions and local coordinated community response teams to engage in primary prevention of intimate partner violence. Grantees' prevention strategies were often developmental and emergent; therefore, CDC's approach to program oversight, administration, and support to grantees required a flexible approach. CDC staff adopted a Data-to Action Framework for the DELTA FOCUS program evaluation that supported a culture of learning to meet dynamic and unexpected information needs. Briefly, a Data-to Action Framework involves the collection and use of information in real time for program improvement. Utilizing this framework, the DELTA FOCUS data-to-action process yielded important insights into CDC's ongoing technical assistance, improved program accountability by providing useful materials, and information for internal agency leadership, and helped build a learning community among grantees. CDC and other funders, as decision makers, can promote program improvements that are data-informed by incorporating internal processes supportive of ongoing data collection and review. PMID- 29189502 TI - Connecting the Dots: State Health Department Approaches to Addressing Shared Risk and Protective Factors Across Multiple Forms of Violence. AB - Violence takes many forms, including intimate partner violence, sexual violence, child abuse and neglect, bullying, suicidal behavior, and elder abuse and neglect. These forms of violence are interconnected and often share the same root causes. They can also co-occur together in families and communities and can happen at the same time or at different stages of life. Often, due to a variety of factors, separate, "siloed" approaches are used to address each form of violence. However, understanding and implementing approaches that prevent and address the overlapping root causes of violence (risk factors) and promote factors that increase the resilience of people and communities (protective factors) can help practitioners more effectively and efficiently use limited resources to prevent multiple forms of violence and save lives. This article presents approaches used by 2 state health departments, the Maryland Department of Health and Mental Hygiene and the Colorado Department of Public Health and Environment, to integrate a shared risk and protective factor approach into their violence prevention work and identifies key lessons learned that may serve to inform crosscutting violence prevention efforts in other states. PMID- 29189505 TI - Development of a Comprehensive and Interactive Tool to Inform State Violence and Injury Prevention Plans. AB - CONTEXT: The Center of Disease Control and Prevention's Core State Violence and Injury Prevention Program (Core SVIPP) provides an opportunity for states to engage with their partners to implement, evaluate, and disseminate strategies that lead to the reduction and prevention of injury and violence. Core SVIPP requires awardees to develop or update their state injury and violence plans. Currently, literature informing state planning efforts is limited, especially regarding materials related to injury and violence. Presumably, plans that are higher quality result in having a greater impact on preventing injury and violence, and literature to improve quality would benefit prevention programming. OBJECTIVE: (1) To create a comprehensive injury-specific index to aid in the development and revision of state injury and violence prevention plans, and (2) to assess the reliability and utility of this index. DESIGN: Through an iterative development process, a workgroup of subject matter experts created the Violence and Injury Prevention: Comprehensive Index Tool (VIP:CIT). The tool was pilot tested on 3 state injury and violence prevention plans and assessed for initial usability. Following revisions to the tool (ie, a rubric was developed to further delineate consistent criteria for rating; items were added and clarified), the same state plans were reassessed to test interrater reliability and tool utility. RESULTS: For the second assessment, reliability of the VIP:CIT improved, indicating that the rubric was a useful addition. Qualitative feedback from states suggested that the tool significantly helped guide plan development and communicate about planning processes. CONCLUSION: The final VIP:CIT is a tool that can help increase plan quality, decrease the research-to-practice gap, and increase connectivity to emerging public health paradigms. The tool provides an example of tailoring guidance materials to reflect academic literature, and it can be easily adapted to other topic areas to promote quality of strategic plans for numerous outcomes. PMID- 29189506 TI - The Power of Academic-Practitioner Collaboration to Enhance Science and Practice Integration: Injury and Violence Prevention Case Studies. AB - One of the most substantial challenges facing the field of injury and violence prevention is bridging the gap between scientific knowledge and its real-world application to achieve population-level impact. Much synergy is gained when academic and practice communities collaborate; however, a number of barriers prevent better integration of science and practice. This article presents 3 examples of academic-practitioner collaborations, their approaches to working together to address injury and violence issues, and emerging indications of the impact on integrating research and practice. The examples fall along the spectrum of engagement with nonacademic partners as coinvestigators and knowledge producers. They also highlight the benefits of academic-community partnerships and the engaged scholarship model under which Centers for Disease Control and Prevention-funded Injury Control Research Centers operate to address the research to-practice and practice-to-research gap. PMID- 29189507 TI - Acute Myeloid Leukemia With Central Nervous System Involvement in Children: Experience From the French Protocol Analysis ELAM02. AB - Central nervous system (CNS) involvement at diagnosis of pediatric acute myeloid leukemia (AML) is not considered as an independent prognostic factor. This study describes the prognostic value of pediatric AML with CNS involvement at diagnosis. Pediatric patients were treated for de novo AML in the French multicenter trial ELAM02. Lumbar puncture was carried out in the first week, and the treatment was adapted to the CNS status. No patient received CNS radiotherapy. The patients were classified into 2 groups: CNS+ and CNS-. Of the 438 patients, 16% (n=70) had CNS involvement at diagnosis, and 29% showed clinical signs. The patients with CNS disease were younger (40% were below 2 y old), had a higher white blood cell count (median of 45 vs. 13 G/L), and had M4 and M5 morphologies. The complete remission rate was similar at 92.8% for CNS+ and 88.5% for CNS-. There was no significant difference between the CNS+ and the CNS- group in overall survival (76% and 71%, respectively) and event-free survival (57% and 52%, respectively). Regarding the occurrence of first relapse, the CNS+ group had a higher combined relapse rate of 26.1% compared with 10% for the CNS- group. The results indicate that CNS involvement at diagnosis of pediatric AML is not an independent prognostic factor. Triple intrathecal chemotherapy combined with high-dose intravenous cytarabine should be the first line treatment for CNS disease. PMID- 29189508 TI - Steroid-induced Hypertension During Induction Chemotherapy for Acute Lymphoblastic Leukemia in US Children's Hospitals. AB - Childhood acute lymphoblastic leukemia achieves excellent cure rates in part due to induction chemotherapy including high dose corticosteroids. Hypertension (HTN) is a known complication of corticosteroids, but incidence and risk factors for steroid-induced HTN are poorly understood. We sought to describe these using a large pediatric health database. Of the 5578 unique patients receiving induction chemotherapy, 14.7% received anti-HTN medications during their initial hospital admission. We found that age below 1 year, obesity, secondary diabetes mellitus, and abnormal glucose were associated with developing steroid-induced HTN. We also found that ICD-9 codes had poor sensitivity for detecting treatment of HTN, suggesting underreporting by physicians.

AB - T-lineage ALL is an aggressive disease that needs to be treated with intensive treatment schedules. A late relapse rarely occurs and a clear choice for second line treatment is on debate. We report on a young adult with a very late isolated extramedullary relapse of PICALM-MLLT10 positive T-ALL, successfully treated with a chemotherapy-based and radiotherapy-based pediatric protocol. We demonstrate that relapse can occur in T-ALL although a SR-MRD behavior treated with a high risk protocol; specific molecular diagnostic aberrations, as PICALM-MLLT10, are still conserved at very late relapse; a second-line treatment based on pediatric protocol can be effective.

AB - BACKGROUND/AIM: The aim of this article is to study the spectrum, changing prevalence, and predictors for mortality of invasive fungal disease (IFD) in pediatric leukemia in a resource-limited setting. OBSERVATIONS: Prevalence was 7% (proven, 69%; probable, 16.4%; possible, 14.6%) and did not differ between acute lymphoblastic leukemia and acute myeloid leukemia. Lungs were frequently involved (46%). Aspergillus was the commonest fungus (47%). Visceral abscesses were frequent with candidiasis as compared with invasive molds (P=0.016). IFD resulted in a prolonged admission (mean, 12.6+/-2 d; P=0.014) and death (44%) (Aspergillus, 50%; Candida, 50%; Mucor, 34%). Diagnosis of acute myeloid leukemia predicted mortality (P=0.03). CONCLUSIONS: IFD was an important cause of treatment related mortality in pediatric leukemia (odds ratio, 8.39). Protocolled use of computed tomography-chest and galactomannan-assay aided diagnosis (P<0.05). PMID- 29189512 TI - The Efficacy of Oral Vitamin B12 Replacement for Nutritional Vitamin B12 Deficiency. AB - Standard treatment of vitamin B12 deficiency has not been well established in childhood, the ideal amount of supplemental vitamin B12 is not clear. Vitamin B12 deficiency is classically treated with intramuscular injections. In this study, we aimed to investigate the efficacy of oral therapy in children with vitamin B12 deficiency. Patients with serum cobalamin concentrations <300 pg/mL aged between 6 months to 18 years were included in this prospective study. Children were treated orally either with a combination of multivitamin tablet daily or vitamin B12 ampules. Serum specimens were obtained at the end of first and third months of treatment for vitamin B12 levels. A total of 79 patients were included in the study. The mean pretreatment vitamin B12 level increased from 182+/-47.6 pg/mL to 482+/-318 pg/mL after 1 month of treatment in the whole cohort. Comparison of the pretreatment vitamin B12 levels with first and third month posttreatment values showed significant difference (P-value, 0.001 and 0.028, respectively). In this study, oral cyanocobalamin was found effective for the treatment of vitamin B12 deficiency in children.

AB - Emberger syndrome with underlying guanine-adenine-thymine-adenine 2 (GATA2) mutation is a rare disorder and very few successful nonmyeloablative allogeneic hematopoietic stem cell transplants (HSCTs) have been reported. We report a case of Emberger syndrome with GATA2 mutation in a 9-year-old girl who presented with congenital sensorineural deafness, warts, lymphedema, and Myelodysplastic syndrome. Her sister had died of a similar illness. She underwent a nonmyeloablative matched related donor peripheral blood HSCT with rabbit antithymoglobulin (5 mg/kg), fludarabine (160 mg/m), cyclophophamide (29 mg/kg), and total body irradiation (2 Gray). Graft versus host disease prophylaxis consisted of tacrolimus and mycophenolate moefetil. She had neutrophil engraftment on day+15 and fully donor chimerism by day+30. She developed limited chronic skin graft versus host disease on tapering off immunosuppression. She is disease free on day+475. The review of literature showed a total of 28 patients with GATA2 mutation have undergone HSCT mostly nonmyeloablative and overall survival is 75%. Nonmyeloablatove HSCT is feasible and safe for the patients with GATA2 mutation. PMID- 29189514 TI - Somatic PTPN11 Mutation in a Child With Neuroblastoma and Protein Losing Enteropathy. AB - Neuroblastoma and protein losing enteropathy (PLE) are diagnoses commonly seen by oncologists and gastroenterologists, respectively. The concurrence of these 2 entities is rare, and not well explained. We describe the sixth case of PLE in a child with neuroblastoma, and the first for which genetic information is available. Tumor DNA had a mutation in the PTPN11 gene, which has been described in neuroblastoma, and in Noonan syndrome-a diagnosis in which neuroblastoma and PLE independently have been reported. Constitutional DNA was normal. Genetic studies in future patients will be needed to support the link between neuroblastoma and PLE. PMID- 29189516 TI - Relationship between concomitant benzodiazepine-opioid use and adverse outcomes among US veterans. AB - Benzodiazepines and opioids are commonly used among veterans suffering from mental health disorders and pain conditions. The objective of this study is to determine whether concomitant benzodiazepine-opioid use increases the incidence of adverse outcomes above the baseline risk of nonacute opioid-only use. The dataset contained all veterans who filled at least 1 opioid prescription during the years 2008 to 2012. Nonacute opioid use was defined as having opioid prescriptions greater than or equal to 20 days within a 60-day period. Concomitant use was defined as having opioid and benzodiazepine prescriptions that overlapped for at least 7 days. Nonacute opioid-only users were matched to concomitant opioid-benzodiazepine users based on propensity scores. A 365-day observation period was used to identify adverse outcomes. The primary outcome examines the existence of one or more of the following outcomes: opioid-related accidents and overdoses, alcohol- and nonopioid drug-related accidents and overdoses, self-inflicted injuries, violence-related injuries, wounds/injuries overall, and death. A logistic propensity score adjusted regression controlling for propensity toward concomitant use was used to determine the association of concomitant use with adverse outcomes. The final matched sample consisted of 396,141 nonacute opioid-only using veterans and 48,971 concomitant benzodiazepine opioid users. Receiving opioids and benzodiazepines concomitantly increased the risk of experiencing an adverse outcome with an odds ratio of 1.359 (95% confidence interval: 1.320-1.400; P < 0.0001). Among veterans receiving opioids, concomitant benzodiazepine use is associated with an increased risk of adverse outcomes when compared to the baseline risk of opioid-only using veterans. PMID- 29189515 TI - Surgical interventions for the treatment of painful neuroma: a comparative meta analysis. AB - A consensus on the optimal treatment of painful neuromas does not exist. Our objective was to identify available data and to examine the role of surgical technique on outcomes following surgical management of painful neuromas. In accordance with the PRISMA guidelines, we performed a comprehensive literature search to identify studies measuring the efficacy of the surgical treatment of painful neuromas in the extremities (excluding Morton's neuroma and compression neuropathies). Surgical treatments were categorized as excision-only, excision and transposition, excision and cap, excision and repair, or neurolysis and coverage. Data on the proportion of patients with a meaningful reduction in pain were pooled and a random-effects meta-analysis was performed. The effects of confounding, study quality, and publication bias were examined with stratified, meta-regression, and bias analysis. Fifty-four articles met the inclusion criteria, many with multiple treatment groups. Outcomes reporting varied significantly and few studies controlled for confounding. Overall, surgical treatment of neuroma pain was effective in 77% of patients [95% confidence interval: 73-81]. No significant differences were seen between surgical techniques. Among studies with a mean pain duration greater than 24 months, or median number of operations greater than 2 prior to definitive neuroma pain surgery, excision and transposition or neurolysis and coverage were significantly more likely than other operative techniques to result in a meaningful reduction in pain (P < 0.05). Standardization in the reporting of surgical techniques, outcomes, and confounding factors is needed in future studies to enable providers to make comparisons across disparate techniques in the surgical treatment of neuroma pain. PMID- 29189517 TI - Can early oral prolonged-release oxycodone with or without naloxone reduce the duration of epidural analgesia after cystectomy? A 3-arm, randomized, double blind, placebo-controlled trial. AB - Thoracic epidural analgesia (TEA) enhances recovery after bowel surgery. Early postoperative prolonged-release oral formulation of oxycodone or oxycodone/naloxone is potentially useful as a second analgesic step to reduce the duration of TEA. We hypothesized that oxycodone would decrease the duration of TEA and combined with naloxone preserve gastrointestinal function. Ninety patients undergoing open cystectomy and urinary diversion were enrolled in this randomized double-blind, three-arm, parallel-group, placebo-controlled single center trial between September 2015 and February 2017. Exclusion criteria were known allergy to oxycodone/naloxone, pulmonary diseases, hepatopathy, and analgesics nonnaive patients. From postoperative day 3, patients received batches with oxycodone, oxycodone/naloxone, or placebo every 12 hours (n = 30 in each arm). Reduction of the epidural drug infusion rate was attempted with the goal to maintain a pain intensity <3 at rest and <5 (numeric rating score) at mobilization during 6 hours. Primary endpoint was duration of TEA and secondary endpoint return of gastrointestinal function. The median duration of TEA did not differ between patients treated with oxycodone/naloxone (6.7 [range 3.1-10.3] days), oxycodone (7.0 [3.0-9.1]), or placebo (6.4 [3.1-8.4]); P = 0.88. Time to the first defecation was prolonged in the oxycodone group compared to the placebo group (difference 22.48 hours +/-8.95; P = 0.037). In the oxycodone group, we found 8/30 patients with ileus (27%) compared to 2/28 (7%) in the oxycodone/naloxone group and to 2/30 (7%) in the placebo group; (P = 0.031). Oxycodone, with or without naloxone, did not reduce the duration of TEA. Oxycodone alone led to a delayed return of bowel function, whereas the combination was not different from placebo. PMID- 29189520 TI - The Middle Ear Muscle Reflex in Rat: Developing a Biomarker of Auditory Nerve Degeneration. AB - OBJECTIVES: The long-term goal of this research is to determine whether the middle ear muscle reflex can be used to predict the number of healthy auditory nerve fibers in hearing-impaired ears. In this study, we develop a high-impedance source and an animal model of the middle ear muscle reflex and explore the influence of signal frequency and level on parameters of the reflex to determine an optimal signal to examine auditory nerve fiber survival. DESIGN: A high impedance source was developed using a hearing aid receiver attached to a 0.06 diameter 10.5-cm length tube. The impedance probe consisted of a microphone probe placed near the tip of a tube coupled to a sound source. The probe was calibrated by inserting it into a syringe of known volumes and impedances. The reflex in the anesthetized rat was measured with elicitor stimuli ranging from 3 to 16 kHz presented at levels ranging from 35 to 100 dB SPL to one ear while the reflex was measured in the opposite ear containing the probe and probe stimulus. RESULTS: The amplitude of the reflex increased with elicitor level and was largest at 3 kHz. The lowest threshold was approximately 54 dB SPL for the 3-kHz stimulus. The rate of decay of the reflex was greatest at 16 kHz followed by 10 and 3 kHz. The rate of decay did not change significantly with elicitor signal level for 3 and 16 kHz, but decreased as the level of the 10-kHz elicitor increased. A negative feedback model accounts for the reflex decay by having the strength of feedback dependent on auditory nerve input. The rise time of the reflex varied with frequency and changed with level for the 10- and 16-kHz signals but not significantly for the 3-kHz signal. The latency of the reflex increased with a decrease in elicitor level, and the change in latency with level was largest for the 10-kHz stimulus. CONCLUSIONS: Because the amplitude of the reflex in rat was largest with an elicitor signal at 3 kHz, had the lowest threshold, and yielded the least amount of decay, this may be the ideal frequency to estimate auditory nerve survival in hearing-impaired ears. PMID- 29189521 TI - Digit Triplet Test Hearing Screening With Broadband and Low-Pass Filtered Noise in a Middle-Aged Population. AB - OBJECTIVES: This study investigated whether age affects Flemish Digit Triplet Test (DTT) scores, as well as sensitivity and specificity of the test to detect high-frequency hearing impairment in middle age. DESIGN: DTT performance in broadband and low-pass filtered noise was assessed for 21 young and 61 middle aged persons with normal-hearing sensitivity. Cutoff values based on their performance were used to evaluate sensitivity and specificity of the DTT as a screening tool in 145 middle-aged persons, with varying audiometric profiles. RESULTS: DTT performance for normal-hearing persons depended on age in both noise conditions. For low-pass filtered noise, the trade-off between sensitivity and specificity also increased when age-adjusted cutoff values were applied for screening in middle age. CONCLUSIONS: The Flemish DTT with broadband noise had high sensitivity and specificity to detect high-frequency hearing impairment in middle age. Similar results were obtained for low-pass filtered noise when cutoff values for referral were age adjusted. PMID- 29189522 TI - Combined Amplification and Sound Generation for Tinnitus: A Scoping Review. AB - OBJECTIVES: In most cases, tinnitus is accompanied by some degree of hearing loss. Current tinnitus management guidelines recognize the importance of addressing hearing difficulties, with hearing aids being a common option. Sound therapy is the preferred mode of audiological tinnitus management in many countries, including in the United Kingdom. Combination instruments provide a further option for those with an aidable hearing loss, as they combine amplification with a sound generation option. The aims of this scoping review were to catalog the existing body of evidence on combined amplification and sound generation for tinnitus and consider opportunities for further research or evidence synthesis. DESIGN: A scoping review is a rigorous way to identify and review an established body of knowledge in the field for suggestive but not definitive findings and gaps in current knowledge. A wide variety of databases were used to ensure that all relevant records within the scope of this review were captured, including gray literature, conference proceedings, dissertations and theses, and peer-reviewed articles. Data were gathered using scoping review methodology and consisted of the following steps: (1) identifying potentially relevant records; (2) selecting relevant records; (3) extracting data; and (4) collating, summarizing, and reporting results. RESULTS: Searches using 20 different databases covered peer-reviewed and gray literature and returned 5959 records. After exclusion of duplicates and works that were out of scope, 89 records remained for further analysis. A large number of records identified varied considerably in methodology, applied management programs, and type of devices. There were significant differences in practice between different countries and clinics regarding candidature and fitting of combination aids, partly driven by the application of different management programs. CONCLUSIONS: Further studies on the use and effects of combined amplification and sound generation for tinnitus are indicated, including further efficacy studies, evidence synthesis, development of guidelines, and recommended procedures that are based on existing knowledge, expert knowledge, and clinical service evaluations. PMID- 29189523 TI - Bilateral Sacral Ala Fractures Are Strongly Associated With Lumbopelvic Instability. AB - OBJECTIVES: To quantify the incidence of lumbopelvic instability in the setting of unilateral and bilateral sacral fractures and assess whether the presence of bilateral sacral fractures on axial imaging is a useful screening test for lumbopelvic instability. DESIGN: Retrospective case series. SETTING: Level I trauma center at an academic medical center. PATIENTS/PARTICIPANTS: A hospital database was used to identify patients diagnosed with a sacral fracture by The International Classification of Diseases, Ninth Revision (ICD-9) code from 2000 to 2014. INTERVENTION: Axial cross-sectional imaging was reviewed to confirm the presence of unilateral or bilateral sacral ala fractures. Sagittal reconstructions were scrutinized for a transverse fracture line separating the lumbar spine from the pelvis, which was used to define lumbopelvic instability. MAIN OUTCOME MEASUREMENTS: The Roy-Camille classification system was applied to all identified cases of lumbopelvic instability. RESULTS: One thousand five hundred twenty-six patients were diagnosed with sacral fractures by the ICD-9 code. Four hundred ninety had adequate axial and sagittal cross-sectional imaging. Four hundred forty-three of these patients had unilateral sacral ala fractures, and none of these were associated with lumbopelvic instability. Forty seven patients had bilateral sacral ala fractures, and 41 of these (87%) had a transverse component indicating some degree of lumbopelvic instability. The presence of bilateral sacral fractures was 100% sensitive and 99% specific for lumbopelvic instability. Among fractures with lumbopelvic instability, 27 (66%) were Roy-Camille type 1, 11 (27%) were type 2, and 3 (7%) were type 3. CONCLUSIONS: Bilateral sacral ala fractures are strongly associated with lumbopelvic instability and can be used as a very sensitive and specific screening tool. All patients with bilateral sacral fractures on axial computed tomography or magnetic resonance imaging should have close assessment of the sagittal plane images to evaluate for this pathology.

PMID- 29189524 TI - Magnitude of Soft-Tissue Defect as a Predictor of Free Flap Failures: Does Size Matter? AB - OBJECTIVES: To examine the relationship between the magnitude of soft-tissue defect and the risk of free-flap and limb-salvage complications/failures. DESIGN: Retrospective cohort. SETTING: Level I Trauma Center. PATIENTS: One hundred twelve patients with free tissue transfers between January 2009 and June 2015. INTERVENTION: A standardized approach using a consistent team of 2 orthopaedic microvascular surgeons was used for each free-flap reconstruction. MAIN OUTCOME MEASURE: Soft tissue defect size, total or partial flap failure, and unplanned reoperations. RESULTS: Of 112 free-flap reconstructions, 57 complications occurred in 43-cases (38%) including 5 total flap failures (4.5%), 7 partial flap failures (6%), and 8 early (7%) and 38 delayed complications (33%). There was a significant correlation between the large defect size (>=200 cm) and partial/total flap failure (n = 80, P = 0.023). There was also a significant correlation between large soft tissue defect size and any complication that is, total or partial failure and early or delayed unplanned return to the operating room (n = 80, P = 0.002). Of the flaps used, multivariate analysis revealed that latissimus flaps had higher odds for failure. CONCLUSIONS: Soft-tissue defect size >=200 cm can be associated with a higher rate of total or partial flap failure and any complication in acute trauma setting, which may be due to a larger zone of injury, a higher level of difficulty in achieving complete debridement, and a more complex microvascular dissection. Current and future efforts will need to continue to focus on risk stratification for limb salvage efforts because an accurate assessment of risk is important to the patient, health care provider, and the health care system in general.

AB - The incidence of periprosthetic fractures have been increasing, and in patients with osteopenic bone, high body mass index, or a combination both, they are difficult to treat and pose a high risk for malunion. Previous studies have compared the use of locking plates and intramedullary nails, and have found that each has its own strengthens and drawbacks, but neither is superior in terms of treating periprosthetic fractures. Here, we present the technique and series of patients treated with a combination of a retrograde intramedullary nail and flare to-flare lateral locking plate without the use of allograft or autograft supplementation. PMID- 29189526 TI - Rib Cage Measurement Reproducibility Using Biplanar Stereoradiographic 3D Reconstructions in Adolescent Idiopathic Scoliosis. AB - BACKGROUND: A reproducibility study of preoperative rib cage three-dimensional (3D) measurements was conducted for patients with Adolescent Idiopathic Scoliosis (AIS). No prior reliability study has been performed for preoperative 3D reconstructions of the rib cage by using stereoradiography in patients with preoperative AIS. Our objective was to assess the reliability of rib cage 3D reconstructions using biplanar stereoradiography in patients with AIS before surgery. METHODS: This series includes 21 patients with Lenke 1 or 2 scoliosis (74+/-20 degrees). All patients underwent low-dose standing biplanar radiographs. Two operators performed reconstructions twice each. Intraoperator repeatability, interoperator reproducibility, and intraclass coefficients (ICC) were calculated and compared between groups. RESULTS: The average rib cage volume was 4.71 L (SD+/-0.75 L). Two SD was 0.19 L with a coefficient of variation of 4.1%; ICC was 0.968. The thoracic index was 0.6 (SD+/-0.1). Two SD was 0.03 with a coefficient of variation of 4.7% and a ICC of 0.820. As for the Spinal Penetration Index (6.4%; SD+/-2.4), 2SD was 0.9% with a coefficient of variation of 14.3% and a ICC of 0.901. The 3D rib hump 2SD (average 27+/-8 degrees) was 1.4 degrees. The coefficient of variation and ICC were respectively 5.1% and 0.991. CONCLUSIONS: Three-dimensional reconstruction of the rib cage using biplanar stereoradiography is a reliable method to estimate preoperative thoracic parameters in patients with AIS.

AB - BACKGROUND DATA: Pedicle screws placement remains technically demanding. The thoracic curve apex is considerably difficult due to its unique morphology and severe rotation. In comparison the upper end vertebrae have smaller pedicles and limited soft tissue exposure. This study seeks to evaluate the likelihood of screw misplacement at the end vertebra and apex. METHODS: A retrospective review of preoperative and postoperative computed tomographic (CT) scans of spinal deformity patients who underwent posterior spinal fusion with pedicle screw constructs between 2004 and 2011 was performed. Pedicles located at the upper instrumented vertebra (UIV) and lower instrumented vertebra (LIV), and the major and minor apices were evaluated. Pedicle morphology was studied on preoperative CT and screw placement on postoperative CT. RESULTS: In total, 188 patients met the inclusion criteria, 172 had preoperative CT scans and 133 had postoperative CT scans. The UIV had a significantly lower percentage of normal pedicles (type A) compared with apex major, apex minor, or LIV (59.1% vs. 76.1% vs. 77.3% vs. 98.7%; P<0.001). UIV had significantly the lowest percentage of normal normally placed screws compared with LIV, apex major, or apex minor (69.4% vs. 97.3% vs. 87.6% vs. 92.1%; P<0.001). In a logistic regression adjusted for preoperative Cobb angles, UIV was more likely to have screws misplaced (odds ratio =7.56; 95% confidence interval, 4.01-14.30; P<0.001) and abnormal pedicles (odds ratio=2.81; 95% confidence interval, 1.52-5.19; P=0.001) compared with any other location studied. In abnormal pedicles, 41 (39.8%) of the 103 UIV screws were misplaced, whereas 10 (16.4%) of the 61 apex major, apex minor, or LIV screws were misplaced (P=0.007). CONCLUSIONS: The UIV presents more of a risk for pedicle screw misplacement and abnormal morphology when compared with LIV and apical vertebra. We believe these findings can aid in the surgeon's preoperative and intraoperative management to ensure increased success in accurate and safe pedicle screw placement. LEVEL OF EVIDENCE: Level III. PMID- 29189528 TI - Incidence and Diagnostic Evaluation of Postoperative Fever in Pediatric Patients With Neuromuscular Disorders. AB - BACKGROUND: Children with neuromuscular disorders have a significant chance of developing scoliosis and/or hip dislocation during childhood and adolescence and often undergo surgical reconstruction. Because of their high rate of medical comorbidities, these patients are at higher risk of postoperative complications and are therefore often comanaged, along with orthopaedics, by pediatric medicine and critical care teams. Fever during the postoperative stay is a frequent occurrence and often prompts extensive diagnostic workup which increases the cost and burden on the health system but have unclear effects on the care of the patient. The objective of our study was to evaluate the frequency of postoperative fever in pediatric patients with neuromuscular disorders after spine and hip deformity correction surgery and evaluate the utility of the diagnostic tests performed for the assessment of postoperative fever. METHODS: We performed an IRB-approved retrospective study on patients who underwent corrective surgery for neuromuscular scoliosis or hip dislocation at a single institution. The occurrence of postoperative fever was characterized by maximum temperature, postoperative day (POD) of occurrence, and frequency as defined by either single or multiple temperature spikes. Diagnostic tests performed for the workup of postoperative fever were reviewed. The cost per health effect was estimated by dividing the total costs of diagnostic tests by the number of tests that changed patient care. RESULTS: In total, 108 patients (62 females and 46 males) were identified. A total of 42 patients (38.9%) underwent posterior spinal fusion and 66 (61.1%) patients underwent hip surgery (pelvic osteotomy in 8 patients, femoral osteotomy in 31 patients, and both pelvic and femoral osteotomy in 27 patients). The mean age at the time of surgery was 11.1 years (range, 3 to 18 y). In total, 66 patients (61.1%) developed postoperative fever (mean temperature, 38.6 degrees C). The frequency of fever was in the form of multiple temperature spikes in 37 patients (56%) and in the form of a single spike in 29 patients (44%). Of the 149 diagnostic tests performed for postoperative fever, there were a total of 16 positive tests (10.7% of total tests ordered; n=16/149) including 5/27 urine analysis, 4/26 urine culture, 4/28 chest x-ray, 1/1 wound culture, 0/1 sputum culture, urine Gram stain 0/1, tracheal aspirate culture 0/1, throat culture 1/1, adenovirus polymerase chain reaction (PCR) 0/5, human metapneumovirus PCR 0/5, parainfluenza PCR 0/5, rhinovirus PCR 0/1, 1/3 bronchoalveolar culture, and 0/7 respiratory virus panel. A total of 37 blood cultures were drawn and all were negative. There was a significant difference (P=0.04) in frequency of negative diagnostic workup performed at the first, second, and third POD as compared with positive diagnostic workup. Total cost of the diagnostic tests was $65,284 and the cost per health effect was $6582 ($65,284/10). Diagnostic tests in patients with postoperative fever were associated with prolonged length of hospital stay in comparison with patients who did not perform any diagnostic workup using the Spearman rho test (P=0.02). CONCLUSION: In total, 61% of pediatric patients developed postoperative fever after surgical correction of neuromuscular deformity. An infectious source of postoperative fever was identified in 32.4% of patients with postoperative fever who underwent diagnostic workup. Urinary tract infection was the most common finding in patients with postoperative fever. Poor association between the development of postoperative fever and wound infection was found. Only 10.7% of fever diagnostic workup tests were positive in our population. The diagnostic workup tests might be less valuable if performed early on the first, second, and third PODs than those performed late after the third POD with exceptions based on clinical assessment. No patients with postoperative fever had positive blood cultures, therefore the routine use of blood cultures in the evaluation of postoperative fever in such population is not recommended.

AB - BACKGROUND: Anterior cruciate ligament (ACL) injuries have been recognized and treated with increasing frequency in children and adolescents. ACL reconstruction (ACLR) in skeletally immature patients has unique considerations and there is a large practice variation in the management of these injuries. The purpose of this study was to survey the members of the Pediatric Research in Sports Medicine (PRiSM) Society regarding their experience with the management and complications of pediatric ACL injuries. METHODS: A 15-question survey was distributed to 71 orthopaedic members of the Pediatric Research in Sports Medicine study group. RESULTS: Regarding treatment of an 8-year-old child with a complete ACL tear, 53% of respondents recommended iliotibial band reconstruction, 33% recommended all epiphyseal reconstruction, and only 3% would treat nonoperatively in a brace. In adolescent patients with 2 years of growth remaining, 47% of respondents recommended a physeal "respecting" technique, 31% recommended a physeal-sparing technique, and 19% would perform an adult-style ACLR. There were 29 new cases of growth arrest reported. CONCLUSIONS: This study demonstrates that there have been major changes in the trends in pediatric ACLR over the past 15 years, and the most treatment variability is found among adolescent patients with about 2 years of growth remaining. The study also demonstrates that while the overall incidence of growth disturbance after ACLR remains low, new cases of growth disturbance continue to be identified.

Two-Year Minimum Follow-up. AB - BACKGROUND: Hip arthroscopy has been shown to be effective in managing various hip pathologies, including labral tears in adolescent patients. The purpose of this study was to ascertain whether outcomes of hip arthroscopy in patients under the age of 18 treated for labral tears differ depending on whether the presentation was acute or chronic. We also present the outcomes of the largest prospectively collected study on hip arthroscopy performed for labral tears in adolescents. METHODS: Patient reported outcome scores (PROs) for 194 patients undergoing hip arthroscopy for hip pathology, who were 18 or under at the time of surgery were prospectively collected and retrospectively reviewed. Modified Harris hip score (mHHS), Nonarthritic hip score (NAHS), Hip Outcome score-sport specific scale (HOS-SSS) and Visual Analogue Score (VAS) were the PROs collected. The overall cohort was assessed for outcome and a comparison was made between those patients who presented with acute onset of symptoms versus those who presented with insidious onset. RESULTS: There was significant improvement in all the PROs for the overall cohort, with improvement maintained over an average of 38.5 months. There was no significant difference in outcome scores, between the acute and chronic groups except for change in VAS. Preoperative scores in the acute group were significantly lower, while postoperative scores did not differ. A trend toward more improvement was noted for the acute group. Overall need for revision surgery was 12%, with a higher rate of revision in the acute group. CONCLUSIONS: Hip arthroscopy in adolescent patients being treated for intra articular pathology is a safe procedure with favorable outcomes at minimum 2-year follow-up, with no significant difference in final outcomes between patients with acute onset of symptoms as opposed to those with more a more chronic presentation. Reoperation rate may be higher in patients with an acute onset. LEVEL OF EVIDENCE: Level II. PMID- 29189531 TI - Characterization of American Football Injuries in Children and Adolescents. AB - BACKGROUND: As a collision sport, football carries a significant risk of injury, as indicated by the large number of pediatric football-related injuries seen in emergency departments. There is little information in the medical literature focusing on the age-related injury patterns of this sport. Our purpose was to evaluate the types of football-related injuries that occur in children and adolescents and assess which patient characteristics, if any, affect injury pattern. METHODS: Retrospective chart review was performed of football-related injuries treated at a level 1 pediatric referral hospital emergency department and surrounding urgent care clinics between January 2010 and January 2014. Patients with e-codes for tackle football selected from the electronic medical record were divided into 4 age groups: younger than 8 years old, 8 to 11, 12 to 14, and 15 to 18 years. Data collected included diagnosis codes, procedure codes, and hospital admission status. RESULTS: Review identified 1494 patients with 1664 football-related injuries, including 596 appendicular skeleton fractures, 310 sprains, 335 contusions, 170 closed head injuries, 62 dislocations, 9 spinal cord injuries, and 14 solid organ injuries. There were 646 (43.2%) athletes with upper extremity injuries and 487 (32.6%) with injuries to the lower extremity. Hospital admissions were required in 109 (7.3%) patients. Fracture was the most common injury in all four patient age groups, but occurred at a lower rate in the 15 to 18 years old age group. The rate of soft tissue injury was higher in the 15 to 18 years old age group. The rate of closed head injury, which included concussions, was highest in the younger than 8 years old age group. CONCLUSIONS: Age does influence the rates of certain football-related injuries in children and adolescents. Fractures decrease with increasing age, while the rate of soft tissue trauma increases with increasing age. Younger patients (younger than 8 y old) trended toward higher rates of closed head injury compared with other age groups. Awareness of these variations in injury patterns based on age could result in age-specific changes in equipment, training, and safety rules. LEVEL OF EVIDENCE: Level IV-case series. PMID- 29189532 TI - Pediatric Supracondylar Humerus Fractures: AAOS Appropriate Use Criteria Versus Actual Management at a Pediatric Level 1 Trauma Center. AB - OBJECTIVES: The purpose of this study was to characterize management of supracondylar humerus fractures (SCHFs) at a level 1 trauma center and identify factors contributing to divergence in management from American Academy of Orthopedic Surgeons (AAOS) the Appropriate Use Criteria (AUC) recommendations. METHODS: A query revealed 556 patients with diagnoses of SCHF between 2013 and 2015 at a pediatric level 1 trauma center. Patients were excluded if they were younger than 2 years of age, older than 12 years of age, were polytrauma patients, or if there was not sufficient clinical or radiographic documentation, resulting in 449 patients. Urgent/emergent intervention was defined as surgery within 8 hours of presentation. Binomial logistic regression assessed whether various factors predicted operative versus nonoperative management. RESULTS: Operative management was undertaken in 0/208 (0%) type I fractures, 61/106 (57.0%) type II fractures, and 135/135 (100%) type III fractures. Comparison with AUC recommendations revealed disagreement in 31% (138/449) of cases. Among 449 patients, 44 were treated nonoperatively despite AUC recommendations for operative treatment. All 44 of these patients were type II SCHFs managed nonoperatively. There were no definitive cases of malalignment or loss of alignment in these nonoperative cases. Factors predictive of operative management were anterior humeral line not intersecting the capitellum (odds ratio, 200; P<0.001) and increasing age (odds ratio, 1.53; P=0.024). The AUC more frequently recommended urgent/emergent operative intervention (148/449, 33.0%) than was performed at our pediatric level 1 trauma center (50/449, 11.1%). The majority of this disagreement (94/98, 95.9%) consisted of uncomplicated type III SCHF treated operatively in >8 hours. None of these patients developed compartment syndrome or required an open reduction. CONCLUSIONS: The American Academy of Orthopedic Surgeons AUC recommended operative and urgent/emergent intervention more frequently than was performed at a level 1 pediatric trauma center. Patient age and alignment of the anterior humeral line with the capitellum, though not specifically addressed in the AUC, were most predictive of operative versus nonoperative management at our institution. PMID- 29189533 TI - Experimental Induction of Physeal Injuries by Fracture, Drill, and Ablation Techniques: Analyses of Immunohistochemical Findings. AB - BACKGROUND: Although physeal fractures and physeal bars can result in significant clinical consequences to growth and development of the injured physis, little orthopaedic research has focused upon this topic. Our objective was to extend a previously developed rat model to examine the immunohistochemical features following surgical application of techniques disrupting the physis. METHODS: Physes were surgically disrupted using fracture (control), epiphyseal scrape (ES), or epiphyseal drill (ED). After 1, 3, 6, 10, or 21 days, animals were euthanized, sites processed for histology and immunohistochemical localization of vascular endothelial growth factor (VEGF), Factor VIII, Sox-9, PTHrP (parathyroid hormone-related protein) and PTHrP-R (parathyroid hormone-related protein receptor) in resting, proliferative, and hypertrophic physeal zones. Incidence of physeal bars, vertical septa and islands within the metaphysis was quantified. Semiquantitative analysis of immunohistochemistry was performed. RESULTS: Physeal bars, vertical septa, and displaced cartilage islands were present each of the surgical treatments. Fisher's exact test showed a statistically significant increase in the presence of physeal bars (P=0.002) and vertical septa (P=0.012) in the ED group at 10 and 21 days. Analysis of VEGF showed significant differences among the surgical treatments involving the resting zone, and the proliferative zone for days 1, 6, and 21 (P<=0.02) with greater mean scores present in the fracture (control) group, followed by the ED group; the lowest scores were present in the ES group. PTHrP-R immunolocalization showed significant differences among treatments in the hypertrophic zone at days 6 and 21 (P=0.022 and 0.044, respectively). CONCLUSIONS: On the basis of the type of surgical treatment, results show significant differences in the presence of VEGF (reflecting the vascular bed) in the resting and proliferating zones at days 1, 6, and 21. VEGF localization was less abundant in the ED group (which had more physeal bars), suggesting that lack of vascular ingrowth plays a role in physeal bar formation. CLINICAL RELEVANCE: Basic science data presented here provide insight into the importance of the various regions of the physis and its repair and continued growth after physeal fracture. We suggest that a better understanding of the cellular basis of physeal arrest following physeal fracture may have future relevance for the development of treatments to prevent or correct arrest. PMID- 29189534 TI - Pediatric Orthopaedic Surgeons Dissatisfied in On-Call Practices Despite Improving Call Conditions. The 2015 POSNA Membership Survey Regarding Trauma Care. AB - BACKGROUND: To examine the current trends in trauma call coverage of pediatric orthopaedic surgeons in North America and to identify predictors of surgeon on call satisfaction. METHODS: In 2015, ~1200 active members of the Pediatric Orthopaedic Society of North America (POSNA) were surveyed regarding emergency room on-call practices. In total, 410 members completed the survey with a response rate of 35%. Information collected included call frequency, practice setting and satisfaction with call. This information was analyzed and compared with the 2006 and 2010 trauma call surveys of Pediatric Orthopaedic Society of North America membership using 2 sample difference in proportion, chi tests for trend and the Fisher exact tests. Logistic regression analyses were used to identify predictors of call satisfaction among pediatric orthopaedic surgeons. RESULTS: In total, 47% of pediatric orthopaedic surgeons had access to a designated trauma operating room in 2015, up from 39% in 2010 and 24% in 2006. In total, 43% of pediatric orthopaedic surgeons currently receive a stipend for taking call, up from 35% in 2010 and 28% in 2006. Although 83% of pediatric orthopaedic surgeons believe that trauma call is an integral part of their practice, only 53% are satisfied with their call experience. Controlling for covariates, believing that call is integral to one's practice doubles odds of call satisfaction. Having resident or fellow support and being financially compensated for orthopaedic trauma call also increases one's odds of satisfaction. The odds of being satisfied with call decrease by 7% for each year of increase in age of the surgeon. CONCLUSIONS: Access to a designated trauma operating room and financial compensation for call coverage have steadily increased over the past decade. A sizable majority of respondents continue to believe that trauma care is an integral part of being a pediatric orthopedist. Despite this, 47% of respondents remain dissatisfied with their trauma call arrangements. The age and attitude of the individual surgeon and extent of hospital support predict satisfaction of surgeons providing trauma coverage. LEVEL OF EVIDENCE: Level V-economic and decision analysis. PMID- 29189535 TI - Torsional Growth Modulation of Long Bones by Oblique Plating in a Rabbit Model. AB - BACKGROUND: There is evidence that oblique tension band plating can affect torsional growth in long bones. This study sought to determine if the torsional growth could be modulated based on the angles of the tension band plating and whether or not oblique plating affected overall longitudinal growth. METHODS: New Zealand White rabbits (10.5 wk old) had one screw placed on the metaphyseal side and one on the epiphyseal side of both medial and lateral sides of the right knee distal femoral physis. The sham group (n=5) included screw placement only. For the plate group (n=13), unlocked plates, angled from 0 to 76 degrees, connected the screws and spanned the physis. Radiographs were taken at biweekly intervals. After 6 weeks of growth, hindlimbs were harvested and microCT scans performed. Femoral length, distances between screw heads and angle between the plates were measured on radiographs. Femoral length differences were compared between groups. Femoral version was measured from 3D microCT. Plate angle changes were correlated to the difference in femoral version between limbs using Pearson correlation (significance was set to P<0.05 for all comparisons). RESULTS: Femur length difference between the contralateral and the operative side was significantly greater in the plate group compared with the sham group over time (P=0.049). Medial and lateral screw distances changed significantly more in the sham group than the plate group on both sides (P<0.001). A greater initial angle between plates resulted in a greater change in the angle between plates (P<0.001). Significant correlations were found between right-left side femoral version differences and initial plate angle (P=0.003) and plate angle change (P=0.014). CONCLUSIONS: The torsional effect of oblique plating seems to correlate with the amount of initial plate angle, with an additional, not negligible, longitudinal growth effect. CLINICAL SIGNIFICANCE: Placing plates at given angles across open physes may result in predictable changes in bone torsion allowing for a safer and less invasive option when treating childhood torsional deformities, but the resulting shortening of the ipsilateral femur must be considered. PMID- 29189536 TI - Incidence of Fractures From Perioperative Blood Pressure Cuff Use, Tourniquet Use, and Patient Positioning in Osteogenesis Imperfecta. AB - BACKGROUND: Osteogenesis imperfecta (OI) is a rare connective tissue disease with varying severity. Patients with OI are highly susceptible to skeletal fractures. Optimal perioperative management of these patients is not well defined. We investigated the risks associated with intraoperative use of noninvasive blood pressure (NIBP) cuffs, tourniquets, and intra-arterial catheters, and patient positioning in children with OI. METHODS: We retrospectively reviewed records of patients younger than 21 years with OI who underwent surgery with general anesthesia from 2010 to 2016 at our tertiary care center. The primary outcome of interest was iatrogenic fracture caused by NIBP cuff use, tourniquet use, or patient positioning. The secondary outcome of interest was complications associated with intra-arterial catheter use. RESULTS: Thirty-seven patients (15 girls) with a mean age of 10+/-4.8 years underwent 96 orthopaedic procedures (lower extremity, upper extremity, and spine) and 2 nonorthopaedic procedures (myringotomy, dental rehabilitation). Blood pressure was monitored with NIBP cuffs in 81 surgeries and intra-arterial catheters in 17 surgeries. Tourniquets (all applied to the lower extremity at a pneumatic pressure of 250 mm Hg) were used to minimize bleeding in 30 surgeries. There were no iatrogenic fractures associated with NIBP cuff use. One patient had a left humerus fracture that occurred during preoperative patient positioning. There were no fractures associated with tourniquet use and no complications related to intra-arterial catheters. CONCLUSIONS: In pediatric patients with OI, intraoperative use of NIBP cuffs and tourniquets was not associated with iatrogenic fracture. There were no complications related to intra-arterial catheter use. Care should be used during the perioperative period to prevent fractures during body positioning. LEVEL OF EVIDENCE: Level IV. PMID- 29189537 TI - Bipolar Sealer Devices Used in Posterior Spinal Fusion for Neuromuscular Scoliosis Reduce Blood Loss and Transfusion Requirements. AB - BACKGROUND: Reducing perioperative blood loss and the need for transfusions in patients undergoing spinal surgery is especially important for those with neuromuscular disorders. These patients require extensive spino-pelvic exposure and are often medically fragile. We have used Amicar to decrease blood loss since 2001. As an effort to further reduce blood loss and transfusions, we use a bipolar sealer device (Aquamantys) as an adjunct to electrocautery. We present the results of our first 64 neuromuscular patients to show the efficacy of the device. METHODS: Using a prospectively maintained database we reviewed the operative time, estimated perioperative blood loss, cell saver use, and intraoperative and postoperative transfusion rate in patients who underwent posterior spinal fusion for neuromuscular scoliosis. Sixty-four patients were identified who fit these criteria since the use of the bipolar sealer device was instituted.We compared these patients with a control group of the preceding 65 patients in whom this device was not used for hemostasis. All patients, including those in the study group, received Amicar (infusion of 100 mg/kg over 15 to 20 min, then 10 mg/kg/h throughout the remainder of the procedure). The surgical technique did not differ between the 2 groups. RESULTS: Baseline characteristics between the 2 groups were similar except for the number of patients having an all screw construct which was larger in the investigational group (25% vs. 8%, P=0.03). There were no significant differences in operative time or duration of hospital stay. Intraoperative blood loss was lower in the study group (741 mL) as compared with the control group (1052 mL, P=0.003). Total perioperative blood loss, however, showed no significant difference. Thirty-five (55%) patients in the study group and 50 (77%) patients in the control group required additional intraoperative or postoperative transfusions (P=0.01). The number of packed red cell units transfused per patient was 0.81 in the study group and 1.57 in the control group (P=0.001). Although the intraoperative cell saver transfusion was same, the total blood volume transfused, which includes cell saver and any other transfusions, was significantly lower in the study group, 425 mL versus 671 mL (P=0.002). CONCLUSIONS: Use of a bipolar sealer device in posterior spinal fusion for neuromuscular scoliosis significantly reduced intraoperative blood loss and transfusion rate when compared with a control group in this retrospective review. LEVEL OF EVIDENCE: Level III-retrospective comparative study. PMID- 29189538 TI - What's New in Pediatric Sports Conditions of the Knee? AB - BACKGROUND: Sports injuries are common in pediatric and adolescent patients and the evaluation and treatment of these injuries continues to evolve. The purpose of this review is to provide a comprehensive appraisal of the literature, highlighting recent updates on sports-related knee injuries in the pediatric athlete. We specifically examined literature on tibial spine fractures, osteochondritis dissecans (OCD) of the knee, and patellar instability. Because of the volume of literature on the subject, pediatric, and adolescent anterior cruciate ligament injuries were not included in this review. METHODS: An electronic search of the PubMed, EMBASE, and Google Scholar databases was performed for keywords related to pediatric: tibial spine fractures, patellar instability, and osteochondritis dissecans (OCD). Search results were filtered by publication date to yield articles published electronically or in print on or after January 1, 2013. Papers were selected based on expert opinion and consensus by the authors and included if deemed to have contributed important findings to the above topics. RESULTS: A total of 31 articles were deemed to have contributed significant findings to the literature: 5 tibial spine, 17 patellar instability, and 9 OCD. The level of evidence for most studies was either level III or IV. CONCLUSIONS: The optimal treatment for tibial spine fractures remains controversial. The evaluation of risk factors for recurrent patellar instability is important in determining the optimal treatment strategy following first-time patellar dislocation. Future multicenter studies on pediatric OCD have the potential to further understanding of this difficult problem. High-level, comparative outcomes research on a variety of pediatric sports related injuries is lacking and this review may help inform topics for future study. LEVEL OF EVIDENCE: Level IV-literature review. PMID- 29189539 TI - Effect of Continuous Systemic Administration of Esmolol on Intraocular Pressure During Surgery in a Sustained Steep Trendelenburg Position. AB - PURPOSE: To investigate the effects of continuous systemic administration of esmolol on intraocular pressure (IOP) during laparoscopic and robotic surgeries for recto-sigmoid cancer in a steep Trendelenburg position. MATERIALS AND METHODS: A total of 50 patients undergoing laparoscopic surgery in a steep Trendelenburg position were included. Patients in the esmolol (E) group received a 0.25 mg/kg IV loading dose of esmolol before anesthesia, followed by an infusion of 15 MUg/kg/min throughout the operation. Patients in the saline (S) group were infused with the same volume of normal saline. IOP and ocular perfusion pressure were measured 16 times: before anesthetic induction (T1), before administration of the study drug (T2), after administration of anesthetic induction agents (T3), after tracheal intubation (T4), 1, 3, 5, and 10 minutes after tracheal intubation (T5-T8), immediately after intraperitoneal CO2 insufflation (T9), immediately after the steep Trendelenburg position (T10), 1, 2, and 4 hours after the steep Trendelenburg position (T11-T13), just before the supine position (T14), and 10 and 30 minutes after the supine position (T15, T16). RESULTS: The IOP increased markedly after adopting the steep Trendelenburg position, reaching 28.8+/-4.4 mm Hg in group S. The IOP at T13 in group S was ~5.7 mm Hg higher than in group E. The IOP at T13 was ~10.6 mm Hg higher than in T1 in group S, but only ~4.4 mm Hg higher than in group E. CONCLUSIONS: Continuous systemic administration of esmolol can alleviate the increase in IOP during a sustained steep Trendelenburg position without adverse cardiovascular effects. PMID- 29189540 TI - The Short-term Effect of Subtenon Sponge Application Versus Subtenon Irrigation of Mitomycin-C on the Outcomes of Trabeculectomy With Ex-PRESS Glaucoma Filtration Device: A Randomized Trial. AB - PURPOSE: Traditionally, during trabeculectomy, Mitomycin-C (MMC) is applied to the tissues using surgical sponges. However, alternate modes of application exist. This study assessed the success rates, complication rates, final intraocular pressure (IOP), and bleb characteristics between patients receiving subtenon MMC application by sponge versus irrigation. PATIENTS AND METHODS: A total of 100 patients with glaucoma were enrolled and each was randomized to 1 of the 2 treatment groups. Patients underwent trabeculectomy with Ex-PRESS shunt and MMC placement and were followed for 6 months. Complication rates assessed included bleb failure, bleb leaks, bleb encapsulation, and hypotony, amongst others. Additional factors evaluated included bleb morphology, glaucoma drop usage, Fluorouracil (5-FU) application, bleb revision, and subsequent glaucoma surgery. RESULTS: The irrigation method provided greater IOP lowering effects (P=0.03); correspondingly the irrigation group had higher rates of hypotony (P=0.03) but with no significant consequences. Patients who had trabeculectomy/Ex PRESS alone had greater IOP reduction than those who had concurrent cataract surgery (P<0.001). The sponge group had higher rates of 5-FU use (P=0.007) and higher reoperation rates (P=0.02) when compared with the irrigation group. Success was defined as achieving 4 mm Hg<=IOP<=15 mm Hg without any anatomical bleb failure or subsequent glaucoma surgery. The overall success rate was 87%. CONCLUSIONS: Application of subtenon MMC by irrigation seems to provide improved short-term outcomes compared with application with sponges. With a similar safety profile, the irrigation method provides better IOP control, and decreases the need for further clinical/surgical intervention in the short-term after trabeculectomy. Longer-term studies will be useful in analyzing if these differences persist with time. PMID- 29189541 TI - A Comparison of Retrobulbar Versus Topical Anesthesia in Trabeculectomy and Aqueous Shunt Surgery. AB - PURPOSE: The purpose of this study was to compare the required supplemental anesthesia and postoperative patient pain score in individuals undergoing glaucoma surgery under topical anesthesia (TA) versus retrobulbar anesthesia (RB). MATERIALS AND METHODS: A retrospective, interventional, comparative cohort study of 261 eyes of 225 patients undergoing glaucoma and combined glaucoma with cataract surgery were included in the study. The main outcome measures were the amount of supplemental, systemic intraoperative anesthesia used and the postoperative pain scale between patients undergoing TA versus RB anesthesia. A secondary analysis was performed between combined glaucoma and cataract surgery versus glaucoma surgery alone. RESULTS: About 6.2% patients complained of pain after glaucoma surgery (8.1% among TA group and 3.1% among RB group; P=0.049). Overall, pain tended to be mild with a mean score of 0.32 of 10 for TA and 0.08 of 10 for RB (P=0.027). The amount of IV anesthetics used intraoperatively was lower in the RB anesthesia compared with the TA group (midazolam, P=0.042; fentanyl, P<0.001; propofol, P<0.001). In addition, patients undergoing RB anesthesia were less likely to use postoperative pain medication (P<0.001). There was no difference in pain score (P=0.707) or in the amount of IV anesthetics (all P>0.350) between eyes undergoing combined versus glaucoma surgery alone. CONCLUSIONS: Although supplemental anesthesia and pain scores were statistically increased in the topical group, the prevalence and the severity of pain was low. Therefore, TA is feasible and a reasonable option for glaucoma surgery. Furthermore, this conclusion applies when glaucoma surgery is performed alone or in combination with the other eye surgery. PMID- 29189542 TI - Implantation of a CyPass Supraciliary Stent Combined With Targeted iStent Trabecular Microbypass Stents in a Phakic Patient With Primary Open-angle Glaucoma. AB - PURPOSE: To report the first successful implantation of a CyPass supraciliary stent combined with 2 targeted iStent trabecular microbypass stents in a phakic primary open-angle glaucoma patient with markedly elevated intraocular pressures (IOP) on maximum tolerable medical therapy. METHODS: Case report. RESULTS: A 52 year-old phakic male patient with primary open-angle glaucoma with uncontrolled IOP in the right eye (OD) of 36 mm Hg on maximal topical pharmacotherapy. The patient underwent implantation of a single CyPass supraciliary stent combined with the targeted implantation of 2 iStent trabecular microbypass stents, 1 right facing stent and 1 left facing stent. Postoperatively, off of all glaucoma medications, the IOP decreased to 10 mm Hg on day 1 and continued to be controlled between 10 to 13 mm Hg until postoperative month 6, with only 1 glaucoma medication added after postoperative month 5. In addition, there were no postoperative complications to date. CONCLUSIONS: The combined implantation of a CyPass supraciliary stent and iStent trabecular microbypass stents can successfully lower IOP and decrease medication burden with minimal risk for complications. PMID- 29189543 TI - Acute Angle-closure Glaucoma Associated With Aripiprazole in the Setting of Plateau Iris Configuration. AB - PURPOSE OF THE STUDY: The purpose of this study was to report a novel case of drug-induced angle-closure from aripiprazole (Abilify), an atypical antipsychotic, and propose a mechanism for this association. METHODS/RESULTS: We report a case of a 45-year-old white woman who presented in subacute angle closure 2 months after initiating aripiprazole 5 mg daily for depression. This patient reported no prior ocular history and had been on longstanding duloxetine (Cymbalta) 60 mg daily for over 10 years before starting aripiprazole. Examination at initial presentation revealed an intraocular pressure (IOP) of 16 mm Hg in the right eye and an elevated IOP of 44 mm Hg in the left eye. Gonioscopy demonstrated a plateau iris configuration in the right eye and angle closure with a plateau iris configuration in the left eye. She was started on IOP lowering therapy and underwent a laser peripheral iridotomy. Despite recommendation to discontinue aripiprazole, duloxetine was discontinued; aripiprazole was maintained and later increased to 10 mg daily for worsening depression. Three months after the dosage increase, the patient was found to have an elevated IOP of 32 mm Hg and angle-closure with a plateau iris configuration in the left eye. Iridoplasty was performed in the left eye with subsequent opening of the angle and improvement in IOP. The second attack of angle-closure led to the discontinuation of aripiprazole and a corresponding widening of the angles in both eyes 1 week after cessation. CONCLUSIONS: This is the first report to describe drug-induced angle-closure glaucoma associated with aripiprazole use. The mechanism of angle closure, we hypothesize, is from mydriasis and/or supraciliary effusion mediated by the serotoninergic effect on the iris and ciliary body complex. Treatment is preferably cessation of the medication. However, in cases where the medication is necessary for management of major depression, iridoplasty should be performed to reduce the risk of angle closure. PMID- 29189545 TI - The Role of Dissemination in Promotion and Tenure for Public Health. PMID- 29189544 TI - Is Obstructive Sleep Apnea Associated With Progressive Glaucomatous Optic Neuropathy? AB - PURPOSE: The purpose of this study was to evaluate the relationship between obstructive sleep apnea syndrome (OSAS) and glaucoma progression, and to examine the correlation between OSAS severity and rate of visual field (VF) loss. METHODS: Patients with concurrent diagnoses of open-angle glaucoma and OSAS between 2010 and 2016 were identified. Enrollment criteria consisted of glaucomatous optic neuropathy and VF loss, >=5 reliable VFs, >=2 years of follow up, and polysomnography (PSG) within 12 months of final VF. PSG parameters including apnea-hypopnea index (AHI) and oxygen saturation (SpO2) were collected. Eyes were classified as "progressors" or "nonprogressors" based upon event analysis using Glaucoma Progression Analysis criteria. Two-tailed t test comparisons were performed, and correlations between rates of VF loss and PSG parameters were assessed. RESULTS: A total of 141 patients with OSAS and glaucoma were identified. Twenty-five patients (age 67.9+/-7.6 y) with OSAS (8 mild, 8 moderate, 9 severe) were enrolled. Eleven eyes (44%) were classified as progressors, and had more severe baseline VF loss (P=0.03). Progressors and nonprogressors had nonsignificantly different (P>0.05) age (69.9+/-8.7 vs. 66.4+/ 6.6 y), follow-up (4.4+/-0.7 vs. 4.3+/-1.0 y), intraocular pressure (13.1+/-2.8 vs. 14.9+/-2.5 mm Hg), mean ocular perfusion pressure (49.7+/-5.5 vs. 48.8+/-9.0 mm Hg), AHI (31.3+/-18.6 vs. 26.4+/-24.0), body-mass index (27.8+/-5.5 vs. 28.8+/ 5.6), and SpO2 (94.1+/-1.6% vs. 94.0+/-1.6%). AHI was not correlated with slopes of VF mean deviation (r, -0.271; P, 0.190) or pattern standard deviation (r, 0.211; P, 0.312), and no substantial increase in risk of progression was found with increase in AHI. CONCLUSIONS: This study does not support a relationship between OSAS and glaucomatous progression. No correlation was observed between OSAS severity and rate of VF loss.

PMID- 29189549 TI - Outcome of Guillain-Barre Syndrome in Tertiary Care Centers in Thailand. AB - BACKGROUND: Guillain-Barre syndrome (GBS), a common acute polyneuropathy, is seen worldwide with significant morbidity and mortality. GBS consists of a number of subtypes. OBJECTIVE: The aim of this study is to identify clinical characteristics, electrophysiologic changes, clinical course, treatment, and outcome of GBS in Thailand. MATERIAL AND METHODS: Retrospective study of GBS patients aged 15 years or older, admitted to Thammasat University Hospital and Bangkok Hospital Medical Center between January 1, 2009 and November 30, 2014. RESULTS: Thirty patients were found. Demographic characteristics were collected and described as follows; 60% male sex; average age 54 years; Asian 60%, European 20%, and others 10%. Disease subtypes consist of acute inflammatory demyelinating polyneuropathy 66.7%, acute motor axonal neuropathy 10%, and others 23.3%. Average GBS disability score at admission was 2.9. Immunotherapy was intravenous immunoglobulin 83.3%, plasma exchange 3.3%, and steroid 3.3%. Average length of stay was 14.2 days; assisted ventilation rate was 13.3%. After the average of 1 year follow-up, average GBS disability score was 1.8, good outcome (score <3) was 63.3% and no death. CONCLUSIONS: Our study suggests that most GBS patients in Thailand are acute inflammatory demyelinating polyradiculoneuropathy (AIDP) subtype and have a good outcome. Predictors of severe disability are older age, previous diarrhea, autonomic disturbances, severe limb or bulbar weakness at admission, or onset of treatment. PMID- 29189550 TI - Pediatric CIDP: Clinical Features and Response to Treatment. AB - OBJECTIVES: Childhood chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) responds favorably to immunomodulatory treatment. However, the optimal sequencing and selection of immunotherapy is uncertain. METHODS: Using accepted diagnostic criteria, pediatric patients with CIDP seen at our center from 1999 to 2015 were identified retrospectively through medical record review. Clinical details and treatment responses were tabulated. RESULTS: Ten patients (age 4-16, 6 women) with definite (N = 8) or possible (N = 2) CIDP met criteria. All were initially treated with IVIg; 6 responded but 4 did not. All 4 IVIG nonresponders improved with twice-weekly high-dose oral prednisone, as did 1 IVIg responder who was also treated with twice-weekly oral prednisone when IVIg was discontinued. Pulse steroids were well tolerated. CONCLUSIONS: Pulse oral corticosteroid therapy holds promise as an alternative treatment to IVIG in pediatric CIDP. Future multicenter studies are warranted to determine the comparative efficacy and safety of weekly pulse oral corticosteroids versus IVIg in pediatric CIDP. PMID- 29189551 TI - Distinguishing Features of the Repetitive Nerve Stimulation Test Between Lambert Eaton Myasthenic Syndrome and Myasthenia Gravis, 50-Year Reappraisal. AB - OBJECTIVE: To reappraise the distinguishing features of the repetitive nerve stimulation (RNS) tests in the abductor digiti quinti muscle between myasthenia gravis (MG) and Lambert-Eaton myasthenic syndrome (LEMS) 50 years after the 1965's Lambert seminal paper. METHODS: The various parameters of the RNS test were compared between 34 patients with LEMS and 140 patients with MG to assess their diagnostic sensitivity. RESULTS: RNS test was abnormal in all (100%) patients with LEMS and 76 (54%) patients with MG. The diagnostic hallmark of LEMS, >=60% increment at high-rate stimulation or postexercise facilitation, was present in 33 (97%) of patients. The diagnostic hallmark of MG, decrement at low rate stimulation (LRS), was present in 65 (46%) of patients with MG. The most prominent difference in the various parameters of RNS tests was noted between LEMS versus MG and normal controls. CONCLUSIONS: Distinguishing features of the RNS test in LEMS and MG are confirmed in this direct comparison study: the low compound muscle action potential amplitude, decrement at LRS, and increment at high-rate stimulation or postexercise facilitation for LEMS and normal compound muscle action potential amplitude and decrement at LRS for MG. PMID- 29189552 TI - Autonomic Reflex Screen Test Abnormalities in Cold-Induced Sweating Syndrome Type 1. AB - Cold-induced sweating syndrome (CISS) is a rare autosomal recessive disease due to mutation in the Cytokine receptor-like factor 1 (CRLF1). The characteristic symptom of CISS is the tendency to sweat profusely especially in the upper body and hands when the patient is exposed to cold temperature. We sought to first report the findings of autonomic reflex screen in a case of CISS type 1 with Cytokine receptor-like factor 1 mutation. Valsalva morphology, Valsalva ratio, and heart rate response to deep breathing were normal for the patient's age. Quantitative sudomotor axon reflex test showed nonlength dependent decrease in the sweat volume. Tilt table revealed evidence of reflex (vasovagal) "syncope," however, the patient was asymptomatic without loss of consciousness. PMID- 29189553 TI - Guillain-Barre Syndrome Triggered by Immune Checkpoint Inhibitors: A Case Report and Literature Review. AB - Immune checkpoint inhibitors, used as immunotherapy in the treatment of melanoma and refractory cancer, may trigger autoimmune disorders. We describe a case of Guillain-Barre syndrome (GBS) after the treatment with ipilimumab and nivolumab and review 4 other reported cases. We confirmed the diagnosis of GBS by electrodiagnostic and cerebrospinal fluid studies. Electrodiagnostic results showed findings consistent with acquired demyelinating polyneuropathy and cerebrospinal fluid showed albuminocytologic dissociation. All patients were treated with intravenous immunoglobulin or other immunomodulating therapy. Among 5 cases which include our patient, 2 did well, 1 did not improve, and 2 died of respiratory insufficiency and multiorgan failure. Enhancing T-cell activation from immune checkpoint inhibitors may trigger GBS which should be suspected when progressive weakness and areflexia occur after treatment with immune checkpoint inhibitors. PMID- 29189554 TI - Paraneoplastic Lambert-Eaton Myasthenic Syndrome With Limbic Encephalitis: Clinical Correlation With the Coexistence of Anti-VGCC and Anti-GABAB Receptor Antibodies. AB - OBJECTIVE: To characterize Lambert-Eaton myasthenic syndrome and limbic encephalitis with coexistent voltage-gated calcium channel (VGCC) antibody and gamma-aminobutyric acid (GABA) B receptor antibody. METHODS: Case study. RESULTS: A 57-year-old man presented with 6 months of weakness, unsteadiness, and vision difficulties. Examination revealed proximal weakness and diminished reflexes. Electrodiagnostic study revealed low-amplitude motor potentials and facilitation on high-frequency stimulation. Laboratory evaluation identified P/Q-type VGCC antibody. Positron emission tomography identified a mediastinal lesion, confirmed as small-cell lung carcinoma. The patient developed confusion and seizures. Cerebrospinal fluid analysis identified antibodies to GABAB receptor. CONCLUSIONS: This case describes a patient with Lambert-Eaton myasthenic syndrome, limbic encephalitis, and autoantibodies to VGCC and GABAB receptor. Atypical presentation of paraneoplastic neurological syndromes could indicate the presence of a second antibody that may have significant impact on therapy.

PMID- 29189567 TI - Transfusion of Red Blood Cells Stored More Than 28 Days is Associated With Increased Morbidity Following Spine Surgery. AB - STUDY DESIGN: A retrospective study. OBJECTIVE: The aim of this study was to describe the association between storage duration of packed red blood cells (PRBCs) and perioperative adverse events in patients undergoing spine surgery at a tertiary care center. SUMMARY OF BACKGROUND DATA: Despite retrospective studies that have shown that longer PRBC storage duration worsens patient outcomes, randomized clinical trials have found no difference in outcomes. However, no studies have examined the impact of giving the oldest blood (28 days old or more) on morbidity within spine surgery. METHODS: The surgical administrative database at our institution was queried for patients transfused with PRBCs who underwent spine surgery between December 4, 2008, and June 26, 2015. Patients undergoing spinal fusion, tumor-related surgeries, and other identified spine surgeries were included. Patients were divided into two groups on the basis of storage duration of blood transfused: exclusively <=28 days' storage or exclusively >28 days' storage. The primary outcome was composite in-hospital morbidity, which included (1) infection, (2) thrombotic event, (3) renal injury, (4) respiratory event, and/or (5) ischemic event. RESULTS: In total, 1141 patients who received a transfusion were included for analysis in this retrospective study; 710 were transfused exclusively with PRBCs <=28 days' storage and 431 exclusively with PRBCs >28 days' storage. Perioperative complications occurred in 119 patients (10.4%). Patients who received blood stored for >28 days had higher odds of developing any one complication [odds ratio (OR) = 1.82; 95% confidence interval (95% CI), 1.20-2.74; P = 0.005] even after adjusting for competing perioperative risk factors. CONCLUSION: Blood stored for >28 days is independently associated with higher odds of developing perioperative complications in patients transfused during spinal surgery. Our results suggest that blood storage duration may be an appropriate parameter to consider when developing institutional transfusion guidelines that seek to optimize patient outcomes.

PMID- 29189568 TI - Tranexamic Acid Decreases Visible and Hidden Blood Loss Without Affecting Prethrombotic State Molecular Markers in Transforaminal Thoracic Interbody Fusion for Treatment of Thoracolumbar Fracture-Dislocation. AB - STUDY DESIGN: A randomized, double-blind, placebo-controlled clinical trial. OBJECTIVE: To evaluate the efficacy and safety of tranexamic acid (TXA) administered during the surgical correction of thoracolumbar fracture dislocation. SUMMARY OF BACKGROUND DATA: Thoracolumbar fracture-dislocation surgery is generally associated with substantial blood loss and a high risk of deep vein thrombosis. TXA has been shown to improve hemostasis in surgical procedures. METHODS: We investigated 80 patients with thoracolumbar fracture dislocation who underwent transforaminal thoracic interbody fusion between March 2014 and December 2016. The patients were randomized into the TXA (n = 39) and Placebo (n = 41) groups, according to whether they did or did not receive pre- and intraoperative TXA treatment. The two groups were compared for demographic characteristics as well as pre- and postoperative levels of prethrombosis-state molecular markers and visible and hidden blood loss volumes. Additionally, the prevalence of TXA-related complications was determined. RESULTS: The two groups did not differ significantly in demographic characteristics. The visible blood loss (intra- and postoperative bleeding during the first 24 h), hidden blood loss, and true total blood loss during surgery in the TXA group were significantly lower than those in the Placebo group (835 +/- 180.3 mL, 351 +/- 82.3 mL, 1385 +/- 102.3 mL vs. 1155 +/- 175.3 mL, 564 +/- 170.5 mL, 1683 +/- 121.0 mL, respectively; P < 0.01). Furthermore, the levels of the prethrombosis state molecular markers GMP-140, fibrinogen, fibrin degradation products, and D dimer were higher in the TXA group than in the Placebo group, although the differences were not significant (P > 0.05). No significant intergroup differences were noted in the prevalence of deep venous thrombosis and pulmonary embolus during the study period. CONCLUSION: TXA significantly reduced visible and hidden blood loss without affecting the prethrombosis-state molecular markers in transforaminal thoracic interbody fusion or causing any notable adverse effects.

OBJECTIVE: To validate the relationship between POC5 and adolescent idiopathic scoliosis (AIS) in the Chinese patients and to further investigate the functional role of POC5. SUMMARY OF BACKGROUND DATA: Three rare functional variants in the POC5 were recently reported to be strongly associated with the disease in a large family with multiple members affected with idiopathic scoliosis. To our knowledge, the association between the mutations of POC5 and AIS remains undetermined in the Chinese population. METHODS: Single nucleotide variants c.1336G>A, c.1286C>T, and c.1363G>C of POC5 were genotyped in 2432 patients with AIS and 2292 healthy controls using multiple ligase detection reactions. Common variants covering POC5 gene were genotyped in 1446 patients and 2080 controls. The mRNA expression of POC5 was determined in the paraspinal muscles collected from 98 patients and 28 controls. The Student t test was used to compare mRNA expression level between the patients and the controls. In addition, the POC5 expression was compared among different genotypes of the remarkably associated single nucleotide polymorphism (SNP) with analysis of variance test. RESULTS: There was no case of mutation for the three reported variants of POC5. SNP rs6892146 was observed to have significantly different distribution of minor allele frequency in the two group (0.485 vs. 0.446, P = 0.004). The mRNA expression of POC5 was 1.5-fold higher in patients than in the controls (0.00012 +/- 0.00009 vs. 0.00008 +/- 0.00006, P = 0.02). Patients with genotype GG have a significantly increased expression of POC5 than those with CC (0.00014 +/- 0.00007 vs. 0.00009 +/- 0.00007, P = 0.03). CONCLUSION: Common variant rs6892146 of POC5 is associated with the development of AIS in the Chinese population. Targeted regional sequencing of POC5 may help identify novel mutations associated with AIS. LEVEL OF EVIDENCE: 4. PMID- 29189570 TI - Facet Sagittal Orientation: Possible Role in the Pathology of Degenerative Lumbar Spinal Stenosis. AB - STUDY DESIGN: A retrospective case-control study. OBJECTIVE: This study aimed to elucidate the association between facet joint orientation and degenerative lumbar spinal stenosis (DLSS). SUMMARY OF BACKGROUND DATA: Many studies have demonstrated the relationship between sagittal facet orientation and degenerative lumbar spondylolisthesis. However, the associations between facet orientation and DLSS have rarely been studied. METHODS: Ninety-one age-matched and sex-matched patients with DLSS (LSS group) and 91 control participants were consecutively enrolled. Their lumbar facet angles and the dural sac cross-sectional area at L2 L3, L3-L4, L4-L5, and L5-S1 were measured using axial magnetic resonance imaging. The intersection angle of the midsagittal line of the vertebra to the facet line represents the orientation of the facet joint. RESULTS: The facet angles on the left side or right side of the LSS group were significantly smaller than the respective ones of the control group. Outcomes of the groups revealed significantly and consistently increasing facet angles from L2-L3 to L5-S1. The dural sac cross-sectional area of the LSS group had significantly smaller measurements values than that of the control group at L2-L3, L3-L4, L4-L5, and L5 S1. CONCLUSION: Sagittalization of lumbar facet joints was considered to be a risk factor for DLSS and may play a role in the pathology of DLSS. LEVEL OF EVIDENCE: 3. PMID- 29189571 TI - Adding Satellite Rods to Standard Two-rod Construct With the Use of Duet Screws: An Effective Technique to Improve Surgical Outcomes and Preventing Proximal Junctional Kyphosis in Posterior-Only Correction of Scheuermann Kyphosis. AB - STUDY DESIGN: A retrospective matched-cohort comparative study. OBJECTIVE: The aim of this study was to compare the surgical results after the use of duet screw based satellite rods and bilateral satellite rods (S-RC) versus a standard two rod construct (2-RC) across osteotomy sites in a matched cohort with Scheuermann kyphosis (SK). SUMMARY OF BACKGROUND DATA: Multiple Ponte osteotomies are frequently employed to correct SK via a posterior-only approach, with a 2-RC across the osteotomy sites. Whereas, correction rate and junction problems remain as the major concerns. METHODS: This study reviewed a consecutive series of patients with SK who had undergone posterior-only correction with multilevel Ponte osteotomy between 2009 and 2014 and had been followed over 24 months. Twenty-two patients receiving placement with an S-RC with the use of duet screws were identified and closely matched with 22 patients with a 2-RC in terms of age, apex, and magnitude of kyphosis. Comparisons were made with regards to deformity magnitude, correction results, complications, and clinical outcomes between the two groups. RESULTS: No significant difference was found between groups in preoperative patient's factors (age, gender, apex, magnitude of kyphosis, and SRS 22 scores) and surgical factors (blood loss, operation time, osteotomy levels, and fused levels). Compared with the 2-RC group, the S-RC group had higher correction rate (55.4% +/- 7.5% vs. 46.2% +/- 5.1%, P < 0.001), less correction loss (1.0 +/- 0.8 degrees vs. 2.4 +/- 1.4 degrees , P < 0.001) during the follow up, and higher improvement of back pain as well (P < 0.05). None were detected with pseudarthrosis or implant failure in either group, but proximal junctional kyphosis was less frequently seen in S-RC group (1 of 22) than 2-RC group (7 of 22) (P < 0.05). CONCLUSION: As a safe method, use of S-RC is effective in providing increased kyphotic correction across multiple Ponte osteotomy levels, and improving patient-reported outcomes of management satisfaction and back pain. The biomechanical benefits of stress dispersion, coupled with increased stability and weight bearing ability, make it a powerful technique preventing correction loss and proximal junctional kyphosis. LEVEL OF EVIDENCE: 3. PMID- 29189572 TI - Immunomodulation of Human Mesenchymal Stem/Stromal Cells in Intervertebral Disc Degeneration: Insights From a Proinflammatory/Degenerative Ex Vivo Model. AB - STUDY DESIGN: Ex vivo experimental study. OBJECTIVE: To investigate the effect of proinflammatory/degenerative intervertebral disc (IVD) microenvironment on the regenerative and immunomodulatory behavior of mesenchymal stem/stromal cells (MSCs), using an ex vivo model from bovine origin. SUMMARY OF BACKGROUND DATA: Low back pain is a cause of disability worldwide, most frequently associated with IVD degeneration and inflammation, and characterized by increased levels of inflammatory mediators, often disregarded. MSC-based therapies to low back pain have been advocated, but the involvement of inflammation in IVD remodeling mechanism, promoted by MSCs has not yet been explored. METHODS: Bovine IVD organ cultures of nucleus pulposus punches were stimulated with needle puncture and culture medium supplementation with 10 ng/mL of interleukin (IL)-1beta, to induce a proinflammatory/degenerative environment, as previously established. Human bone marrow-derived MSCs were cultured on top of transwells, placed above nucleus pulposus punches, for up to 16 days. MSCs were analyzed by screening cell viability/apoptosis, metabolic activity, migration, and inflammatory cytokines production in response to the proinflammatory environment. IVD extracellular matrix (ECM) remodeling, gene expression profile of IVD cells, and inflammatory cytokine profile in the presence of MSCs in basal versus proinflammatory conditions were also evaluated. RESULTS: Proinflammatory/degenerative IVD conditions did not affect MSCs viability, but promoted cell migration, while increasing IL-6, IL-8, monocyte chemoattractant protein-1, and prostaglandin E2 and reducing transforming growth factor-beta1 production by MSCs. MSCs did not stimulate ECM production (namely type II collagen or aggrecan) in neither basal nor inflammatory conditions, instead MSCs downregulated bovine proinflammatory IL 6, IL-8, and TNF-alpha gene expression levels in IL-1beta-stimulated IVDs. CONCLUSION: The present study provides evidence for an immunomodulatory paracrine effect of MSCs in degenerated IVD without an apparent effect in ECM remodeling, and suggest an MSCs mechanism-of-action dependent on a cytokine feedback loop. LEVEL OF EVIDENCE: 5. PMID- 29189573 TI - Quality of Life and Health Utility Scores Among Canadians Living With Traumatic Spinal Cord Injury - A National Cross-Sectional Study. AB - STUDY DESIGN: National, multicenter, cross-sectional study. OBJECTIVE: The goal of this study was to provide overall quality of life (QOL) and health utility (HU) values for patients with traumatic spinal cord injury (SCI) stratified by injury level and neurological status. SUMMARY OF BACKGROUND DATA: Traumatic SCI is a leading cause of disability. Varying injury level and severity generate a spectrum of neurological dysfunction and reduction in long-term QOL. METHODS: The Canadian SCI Community Survey was sent to Canadians living in the community after SCI. The impact of demographics, complications, and SCI classification on QOL was assessed using Analysis of variance, multiple linear regressions and ordinal logistic regression analyses. RESULTS: There were 1109 respondents with traumatic SCI. american spinal injury association impairment scale (AIS) grade was reported to be cervical motor complete in 20%, cervical motor incomplete in 28%, thoracolumbar motor complete in 32%, thoracolumbar motor incomplete in 16%, and normal (any level) in 1%. Injury level or AIS grade had no impact on either HU or QOL. The physical component of health-related quality of life (HRQOL) was significantly affected by the neurological level, but not the social or mental components. With a mean health utility score of 0.64 +/- 0.12, SCI patients living in the community reported having HRQOL similar to patients after total knee arthroplasty or lumbar spinal stenosis decompression. CONCLUSION: QOL or HU measured by generic HRQOL outcome tools should not be used as outcomes to assess the effectiveness of interventions targeting neurological function in traumatic SCI. A disease-specific instrument that captures the nuances specific to spinal cord injury patients is required. LEVEL OF EVIDENCE: 1. PMID- 29189574 TI - The Role of Mental Health Disease in Potentially Preventable Hospitalizations: Findings From a Large State. AB - BACKGROUND: Preventable hospitalizations are markers of potentially low-value care. Addressing the problem requires understanding their contributing factors. OBJECTIVE: The objective of this study is to determine the correlation between specific mental health diseases and each potentially preventable hospitalization as defined by the Agency for Healthcare Research and Quality. DESIGN/SUBJECTS: The Texas Inpatient Public Use Data File, an administrative database of all Texas hospital admissions, identified 7,351,476 adult acute care hospitalizations between 2005 and 2008. MEASURES: A hierarchical multivariable logistic regression model clustered by admitting hospital adjusted for patient and hospital factors and admission date. RESULTS: A total of 945,280 (12.9%) hospitalizations were potentially preventable, generating $6.3 billion in charges and 1.2 million hospital days per year. Mental health diseases [odds ratio (OR), 1.25; 95% confidence interval (CI), 1.22-1.27] and substance use disorders (OR, 1.13; 95% CI, 1.12-1.13) both increased odds that a hospitalization was potentially preventable. However, each mental health disease varied from increasing or decreasing the odds of potentially preventable hospitalization depending on which of the 12 preventable hospitalization diagnoses were examined. Older age (OR, 3.69; 95% CI, 3.66-3.72 for age above 75 years compared with 18-44 y), black race (OR 1.44; 95% CI, 1.43-1.45 compared to white), being uninsured (OR 1.52; 95% CI, 1.51-1.54) or dual-eligible for both Medicare and Medicaid (OR, 1.23; 95% CI, 1.22-1.24) compared with privately insured, and living in a low-income area (OR, 1.20; 95% CI, 1.17-1.23 for lowest income quartile compared with highest) were other patient factors associated with potentially preventable hospitalizations. CONCLUSIONS: Better coordination of preventative care for mental health disease may decrease potentially preventable hospitalizations.

PMID- 29189576 TI - Predicting High Health Care Resource Utilization in a Single-payer Public Health Care System: Development and Validation of the High Resource User Population Risk Tool. AB - BACKGROUND: A large proportion of health care spending is incurred by a small proportion of the population. Population-based health planning tools that consider both the clinical and upstream determinants of high resource users (HRU) of the health system are lacking. OBJECTIVE: To develop and validate the High Resource User Population Risk Tool (HRUPoRT), a predictive model of adults that will become the top 5% of health care users over a 5-year period, based on self reported clinical, sociodemographic, and health behavioral predictors in population survey data. RESEARCH DESIGN: The HRUPoRT model was developed in a prospective cohort design using the combined 2005 and 2007/2008 Canadian Community Health Surveys (CCHS) (N=58,617), and validated using the external 2009/2010 CCHS cohort (N=28,721). Health care utilization for each of the 5 years following CCHS interview date were determined by applying a person-centered costing algorithm to the linked health administrative databases. Discrimination and calibration of the model were assessed using c-statistic and Hosmer-Lemeshow (HL) chi statistic. RESULTS: The best prediction model for 5-year transition to HRU status included 12 predictors and had good discrimination (c statistic=0.8213) and calibration (HL chi=18.71) in the development cohort. The model performed similarly in the validation cohort (c-statistic=0.8171; HL chi=19.95). The strongest predictors in the HRUPoRT model were age, perceived general health, and body mass index. CONCLUSIONS: HRUPoRT can accurately project the proportion of individuals in the population that will become a HRU over 5 years. HRUPoRT can be applied to inform health resource planning and prevention strategies at the community level. PMID- 29189577 TI - Estimating Associations Between Medical Home Adoption, Utilization, and Quality: A Comparison of Evaluation Approaches. AB - BACKGROUND: Methodological differences between evaluations of medical home adoption might complicate readers' ability to draw conclusions across studies. OBJECTIVES: To study whether associations between medical home adoption and patient care are affected by methodological choices. DESIGN, SETTING, AND SUBJECTS: Among 71 practices participating in the Pennsylvania Chronic Care Initiative (a medical home pilot), we estimated cross-sectional and longitudinal associations between 4 definitions of "medical home adoption" [National Committee on Quality Assurance (NCQA) recognition in year 3, Medical Home Index scores at baseline and 3, and within-practice changes in Medical Home Index scores between baseline and year 3] and utilization and quality. MEASUREMENTS: Six utilization and 6 quality measures. RESULTS: In cross-sectional analyses at year 3, NCQA recognition was associated with higher rates of nephropathy monitoring (7.23 percentage points; confidence interval, 0.45-14.02), breast cancer screening (7.48; 2.11-12.86), and colorectal cancer screening (8.43; 2.44-14.42). In longitudinal analyses, NCQA recognition was associated with increases in hospitalization rates (2.75 per 1000 patient-months; 0.52-4.98). In baseline cross-sectional analyses, higher Medical Home Index scores were associated with fewer ambulatory care-sensitive hospitalizations (-0.61 per 1000 patient per month; -1.11 to -0.11), all-cause emergency department visits (-6.80; -12.28 to 1.32), and ambulatory care-sensitive emergency department visits (-5.60; 10.32 to -0.88). There were no statistically significant associations between any other measure of medical home adoption and quality or utilization. CONCLUSIONS: The findings of medical home evaluations are sensitive to methodological choices. Meta-analyses, narrative reviews, and other syntheses of medical home studies should consider subdividing their findings by analytic approach. PMID- 29189579 TI - Physical Demands of Exergaming in Healthy Young Adults. AB - Tietjen, AMJ and Devereux, GR. Physical demands of exergaming in healthy young adults. J Strength Cond Res XX(X): 000-000, 2017-The efficacy of whole-body exergaming (WBE) in healthy young adults remains largely unknown. This study aimed to: (a) compare the physical demands of WBE in healthy adults with traditional exercise; (b) determine whether the physical demands of WBE were reproducible. Twenty-five healthy adults (age: 22.9 +/- 6.4 years; height: 1.7 +/ 0.1 m; mass: 69.1 +/- 12.2 kg) completed two 10-minute experimental conditions (WBE on the Xbox Kinect and treadmill walking) in a randomized cross-over design study. Whole-body exergaming produced a significant increase in the peak heart rate (138 +/- 23 b.min), oxygen consumption (40 +/- 13 ml.kg.min), metabolic equivalents (METs) (11 +/- 4) compared with treadmill walking (115 +/- 18 b.min, 25 +/- 5 ml.kg.min, 7 +/- 2 MET) and a modest increase in the mean heart rate (111 +/- 19 b.min vs. 104 +/- 15 b.min). Whole-body exergaming produced significantly greater vertical (381 +/- 118 vs. 127 +/- 14 % body weight [%BW]), anterior (70 +/- 22 vs. 27 +/- 4 %BW), and medial (56 +/- 21 vs. 7 +/- 2 %BW) ground reaction forces. No difference was present in mean oxygen consumption and MET. The reproducibility of WBE was assessed in a subgroup of 11 participants (age: 24.2 +/- 6.7 years; height: 1.8 +/- 0.1 m; mass: 75.3 +/- 10.0 kg), who completed 2 additional 10-minute WBE sessions. No difference was observed between all outcome measures. These findings indicate that WBE can reliably replicate, or surpass, the physical demands of treadmill walking and may serve as an effective addition to a health-focused exercise program.

Validity of an isometric midthigh pull dynamometer in male youth athletes. J Strength Cond Res 32(2): 490-493, 2018-The purpose of this study was to investigate the validity of an isometric midthigh pull dynamometer against a criterion measure (i.e., 1,000-Hz force platform) for assessing muscle strength in male youth athletes. Twenty-two male adolescent (age 15.3 +/- 0.5 years) rugby league players performed 4 isometric midthigh pull efforts (i.e., 2 on the dynamometer and 2 on the force platform) separated by 5-minute rest in a randomized and counterbalanced order. Mean bias, typical error of estimate (TEE), and Pearson correlation coefficient for peak force (PF) and peak force minus body weight (PFBW) from the force platform were validated against peak force from the dynamometer (DynoPF). When compared with PF and PFBW, mean bias (with 90% confidence limits) for DynoPF was very large (-32.4 [-34.2 to -30.6] %) and moderate (-10.0 [-12.8 to -7.2] %), respectively. The TEE was moderate for both PF (8.1 [6.3-11.2] %) and PFBW (8.9 [7.0-12.4]). Correlations between DynoPF and PF (r 0.90 [0.79-0.95]) and PFBW (r 0.90 [0.80-0.95]) were nearly perfect. The isometric midthigh pull assessed using a dynamometer underestimated PF and PFBW obtained using a criterion force platform. However, strong correlations between the dynamometer and force platform suggest that a dynamometer provides an appropriate alternative to assess isometric midthigh pull strength when a force platform is not available. Therefore, practitioners can use an isometric midthigh pull dynamometer to assess strength in the field with youth athletes but should be aware that it underestimates peak force.

AB - Fields, JB, Metoyer, CJ, Casey, JC, Esco, MR, Jagim, AR, and Jones, MT. Comparison of body composition variables across a large sample of National Collegiate Athletic Association women athletes from 6 competitive sports. J Strength Cond Res 32(9): 2452-2457, 2018-Body composition (BC) plays a critical role in sport performance and athlete health. Body size and BC have been widely studied in men's sports, with reported changes observed over time. However, a paucity of current data exists in women athletes. The purpose of this descriptive study was to measure and compare BC data for collegiate women athletes from 6 competitive sports. A total of 524 athletes from 2 National Collegiate Athletic Association institutions participated: basketball (BB; n = 95), gymnastics (GYM; n = 42), lacrosse (LAX; n = 81), rowing (ROW; n = 57), soccer (SOC; n = 188), and volleyball (VB; n = 61). Body height (BH) and body mass (BM) were measured using a stadiometer and calibrated digital scale, respectively. Body fat percentage (BF%), fat mass (FM), and fat-free mass (FFM) were assessed using air displacement plethysmography. One-way analysis of variance was used to assess differences across sports. Least squares difference post hoc analyses were performed when a significant finding (p <= 0.05) was identified. ROW had the highest BF% (29.9 +/- 6.1%) and BB the greatest FFM (57.2 +/- 6.1 kg). GYM had the lowest BM (58.9 +/- 5.3 kg), FM (11.6 +/- 2.6 kg), and BH (158.73 +/- 2.13 cm). LAX, SOC, and VB had similar BF%. Body height was greatest for BB and VB (177.92 +/- 7.55 cm, 176.79 +/- 7.36 cm, respectively). These data may assist in the establishment of descriptive values for use in goal setting and exercise programming. The current data demonstrate a trend toward increased body size and BC from previous research.

Impact of 10 minute interval roller massage on performance and active range of motion. J Strength Cond Res XX(X): 000-000, 2017-Roller massage (RM) has been shown to increase range of motion (ROM) without subsequent performance deficits. However, prolonged static stretching (SS) can induce performance impairments. The objective of this study was to examine the effects of combining SS and RM with and without subsequent RM on ROM and neuromuscular performance. Subjects (n = 12) participated in 5 sessions: (a) SS only (SS_rest), (b) SS + RM (SS + RM_rest), (c) SS with RM at 10 and 20 minutes after stretch (SS_RM), (d) SS + RM with RM at 10 and 20 minutes after stretch (SS + RM_RM), and (e) control. For the SS conditions, the quadriceps and hamstrings received passive SS for 2 * 30 seconds each. For the SS + RM conditions, SS was applied to the quadriceps and hamstrings for 30 seconds each, and RM was performed for 30 seconds per muscle. SS_RM and SS + RM_RM conditions received an additional 30-second RM at 10 and 20 minutes after warm-up, whereas sessions without additional RM rested for the same duration. Testing measures included hip flexion (HF) and knee flexion (KF) active and passive ROM, hurdle jump height and contact time, countermovement jump height, and maximal voluntary isometric contraction force. Initial KF and HF ROM improvements provided by SS_RM and SS + RM_RM were sustained up to 30 minutes after intervention. Furthermore, SS_RM exhibited greater ROM compared with sessions lacking additional RM in active and passive HF as well as active and passive KF. Similarly, SS + RM_RM elicited greater KF and HF ROM improvements than SS_rest. In conclusion, active KF and HF ROM improvements were prolonged by additional RM, whereas neuromuscular performance remained relatively unaffected.

J Strength Cond Res XX(X): 000 000, 2017-The aim of this study was to examine the aerobic fitness status of top class male soccer officials using a cross-sectional design and known population group constructs. Fifty-two field referees (FRs, age 38.4 +/- 3.3 years; height 181 +/- 5.6 cm; body mass 76.8 +/- 6.8 kg; body mass index [BMI] 23.4 +/- 1.7 kg.m; body fat 20.4 +/- 3.6%; and international refereeing experience 5 +/- 3.5 years) and 104 assistant referees (ARs, age 37.8 +/- 4.1 years; height 176.9 +/- 7.5 cm; body mass 72.1 +/- 7.4 kg; BMI 23 +/- 1.6 kg.m; body fat 19.2 +/- 3.6%; and international refereeing experience 7 +/- 3.8 years) from 53 National Football Associations worldwide, and candidates of the preliminary open-list developed by the FIFA Refereeing Department for the 2014 World Cup Final Tournament, were tested for aerobic fitness in laboratory conditions with a progressive speed treadmill test to exhaustion. Large (+8.54%, d = 0.8) and small (+3.1%, d = 0.3) differences in absolute (L.min) and relative (ml.kg.min) V[Combining Dot Above]O2max were found between FR and AR, respectively. Trivial differences (d = 0.07) were shown in running economy (RE) (6 minutes at 8 km.h) between AR and FR. Using the scaling notation (b = 0.64), medium and significant differences were found between match officials for V[Combining Dot Above]O2max and RE (FR > AR; d = 0.6 and 0.67, respectively). Using receiver operating characteristic curve statistics, cutoff values of 3.93 L.min and 50.6 ml.kg.min were detected in absolute and relative V[Combining Dot Above]O2max for the FR and the AR (FR > AR), respectively. The FR showed superior aerobic fitness compared with AR. Training prescription should consider intensities at anaerobic threshold speed (14 km.h, 91% heart rate max) when aerobic fitness development is the aim in elite officials. PMID- 29189583 TI - Modeling Fitness Variable Responses To Training In Prepubescent Children. AB - The aim of this study was to determine strength and oxygen uptake (VO2max) performances according to different training program intervention design with 8 weeks duration in prepubescent children through a multiple linear regression models. Two hundred and forty-five healthy prepubescent children (aged 10.9 +/- 0.5 years) were randomly assigned to a specific training program (strength training only - S; aerobic training only - A; intra-session aerobic and strength training - AS; intra-session strength and aerobic training - SA; or concurrent training performed in different sessions - CT) or a control group (no training regimen - C). It was possible to develop indirect predictive models for each training method, by including each variable pre-training, body fat percentage and body mass index. The models provided explained 82% of variance in the VO2max, 98% in the 1kg ball-throw, 96% in the 3kg ball-throw, 92% in the counter-movement jump, 93% in the standing long jump and 98% in the 20m sprint performances. This novel approach to training evaluation and control aims to provide a tool to allow professionals to calculate changes with a high confidence level (CI 95%), to control gains and to choose the best training methodology to apply according to the defined purposes. The results of this study could be a great support to teachers, coaches and professionals providing important tools to improve the efficacy and individualization of training. PMID- 29189584 TI - Body Image Amongst Elite Rugby Union Players. AB - There is limited information on the risk of eating disorders and body image of elite male athletes. However, research suggests there are some athletes who have poor body image and they may be at increased risk of developing eating disorders. Therefore, the current study investigated risk of eating disorders, body image, and the relationship with age, in elite rugby union players during their pre season training period.This cross-sectional study was undertaken at the start of the pre-season amongst elite rugby union players in New Zealand. Twenty-six professional rugby union players completed a 49-item questionnaire on body image and disordered eating. A 'body image score' was calculated from questionnaire subscales including 'drive for thinness', 'bulimia' and 'body dissatisfaction', with total scores above twenty indicative of poor body image.Body image scores varied from 8-39 out of a possible 0-100. Disordered eating behaviours were reported, including binge eating at least once a week (15%, n=4/26), pathogenic weight control use (4%, n=1/26) and avoidance of certain foods (77%, n=20/26). There was a statistically significant inverse association between the bulimia subscale and age (P = 0.034).At the start of the pre-season training period, many elite rugby union players experience disturbances in body image. The prevalence of disordered eating behaviours is of concern, and needs to be minimised due to the negative impact on health and performance. A focus on assessment and education of younger male rugby players may be required in order to reduce disordered eating patterns. PMID- 29189585 TI - Muscle Damage and Metabolic Responses to Repeated-Sprint Running With and Without Deceleration. AB - Minahan, CL, Poke, DP, Morrison, J, and Bellinger, PM. Muscle damage and metabolic responses to repeated-sprint running with and without deceleration. J Strength Cond Res XX(X): 000-000, 2017-This study aimed to determine whether repeated-sprint running with deceleration aggravates markers of muscle damage or delays the recovery of performance compared with repeated-sprint running without deceleration. Fourteen male team-sport athletes performed 2 randomly ordered testing sessions on a nonmotorized treadmill with one session requiring participants to decelerate (TMd) within 4 seconds before stopping or immediately step to the side of the treadmill belt at the completion of each sprint (TMa). Peak and mean velocities, speed decrement, blood lactate concentrations, and oxygen uptake were monitored during the repeated-sprint running protocols. Countermovement vertical jump (CMJ) performance, perceived muscle soreness, sit and-reach flexibility, plasma creatine kinase (CK), lactate dehydrogenase (LDH), and myoglobin (Mb) concentrations were quantified immediately before and after and 45 minutes, 24 and 48 hours after repeated-sprint running protocols. Although muscle damage was indicated by increases in CK, LDH, and Mb (p <= 0.05) in both groups, there was no significant effect of condition (TMa vs. TMd) on any of the measured performance or physiological variables (p > 0.05). The present study indicated that the removal of deceleration from repeated-sprint running on a nonmotorized treadmill has no effect on metabolism or performance during or after repeated-sprint running or markers of muscle damage. PMID- 29189586 TI - Potential Utility of a Loaded Treadmill Protocol for Tactical Athletes. AB - Swearingen, JT, Weiss, LW, Smith, WA, Stephenson, MD, and Schilling, BK. Potential utility of a loaded treadmill protocol for tactical athletes. J Strength Cond Res 32(3): 610-616, 2018-Aerobic capacity is an important variable for tactical athletes, with V[Combining Dot Above]O2max being the most direct way of estimating it in a laboratory setting. A mode-specific protocol involving fixed-weight, torso-borne loads was assessed in the current study. On 4 separate days, 15 men (age 22.1 +/- 2.7 years, mass 85.1 +/- 10.6 kg, height 179.0 +/- 7.7 cm) performed a weighted treadmill walking protocol (2 trials) and a nonweighted treadmill running protocol (2 trials). Both the weighted and nonweighted protocols were reliable, with intraclass correlation coefficient values of 0.79 and 0.87, respectively. V[Combining Dot Above]O2peak values from both protocols were highly correlated (r = 0.90, p < 0.01). However, V[Combining Dot Above]O2peak was higher during the nonweighted protocol (t = 7.547, d = 2.47, p < 0.01). Work rate was calculated for both the last completed stage and stage during which participants reached fatigue. Work rates for both protocols on the last completed stage were similar (t = 1.44, d = 0.83, p = 0.17), although the work rate for the final attempted stage was greater for the weighted-walking protocol (t = 5.85, d = 3.60, p < 0.01). These data suggest a weighted-walking V[Combining Dot Above]O2peak that is highly associated with a running V[Combining Dot Above]O2peak. This test may be applied to those who routinely perform torso borne load carriage, such as tactical athletes. Future weighted-walking protocols should seek achieve higher resolution, especially near the end stage of the test where subjects reach volitional fatigue. Large increases in work rate may not be feasible at the end stages of the test. PMID- 29189587 TI - Effect of Cold (14 degrees C) vs. Ice (5 degrees C) Water Immersion on Recovery From Intermittent Running Exercise. AB - Anderson, D, Nunn, J, and Tyler, CJ. Effect of cold (14 degrees C) vs. ice (5 degrees C) water immersion on recovery from intermittent running exercise. J Strength Cond Res 32(3): 764-771, 2018-The purpose was to compare 14 degrees C (CWI14 degrees C) and 5 degrees C (CWI5 degrees C) cold water immersion after intermittent running. On 3 occasions, 9 male team-sport players undertook 12 minutes of CWI14 degrees C, CWI5 degrees C, or nonimmersed seated recovery (CON) after 45 minutes of intermittent running exercise. Maximal cycling performance and markers of recovery were measured before and in the 0-72 hours after exercise. Peak power output (PPO) was immediately reduced after all interventions (d = 1.8). CWI5 degrees C was more effective at restoring PPO than CWI14 degrees C (d = 0.38) and CON (d = 0.28) 24 hours after exercise, whereas both CON (d = 0.20) and CWI5 (d = 0.37) were more effective than CWI14 degrees C after 48 hours. Cold water immersion (CWI) was more effective than CON at restoring PPO 72 hours after exercise (d = 0.28-0.30). Mean power output (MPO) was higher in CON compared with CWI5 degrees C (d = 0.30) and CWI14 degrees C (d = 0.21), but there was no difference between CWI5 degrees C and CWI14 degrees C (d = 0.08). CWI5 degrees C was more effective than CWI14 degrees C for restoring MPO to baseline levels 24 hours (d = 0.28) and 72 hours (d = 0.28) after exercise; however, CON was more, or equally, effective as CWI5 degrees C and CWI14 degrees C throughout. Lactate and creatine kinase concentrations were unaffected. Perceived muscle soreness remained elevated in CWI5 and CON throughout but was similar to baseline in CWI14 degrees C after 72 hours. In conclusion, repeated bouts of exercise are initially impaired after 5 and 14 degrees C CWI, but PPO may be improved 72 hours after exercise. Cold water immersion is not recommended for acute recovery based on these data. Athletes and coaches should use the time currently allocated to CWI for more effective and alternative recovery modalities. PMID- 29189588 TI - A randomized phase II study of S-1 versus capecitabine as first-line chemotherapy in elderly metastatic gastric cancer patients with or without poor performance status: clinical and pharmacogenetic results. AB - OBJECTIVE: This study investigated the efficacy and safety of S-1 versus capecitabine in elderly patients with metastatic gastric cancer (MGC), and examined the association between cytochrome P450 2A6 (CYP2A6) polymorphisms and treatment outcomes. MATERIALS AND METHODS: MGC patients 70-85 years old with Eastern Cooperative Oncology Group (ECOG) performance status 0-2 or 65-70 years old with ECOG PS 2 were randomized to receive S-1 40 mg/m, twice daily, or capecitabine 1250 mg/m, twice daily, on days 1-14 every 3 weeks. RESULTS: From May 2007 up to July 2010, 107 patients were enrolled. G3/4 neutropenia developed in 3.8% of each arm, and the most common G3/4 nonhematological toxicities were anorexia and fatigue. Vomiting and tearing were more frequent with S-1 and hand foot syndrome with capecitabine. The primary endpoint, the overall response rate, was 26.4% (14/53, 95% confidence interval: 14.5-38.3%) in S-1 and 24.1% (13/54, 95% confidence interval: 12.7-35.5%) in capecitabine, both of which exceeded the null hypothesis response rate of 10%. The median time to progression (TTP; 3.2 vs. 3.4 months, P=0.813) and overall survival (OS; 8.5 vs. 10.3 months, P=0.691) were similar in both arms. CYP2A6 polymorphisms were associated with S-1 efficacy. In the S-1 arm only, patients with CYP2A6 variant/variant alleles had worse TTP and OS than those with wild/wild or wild/variant alleles, and in multivariate analysis, the CYP2A6 genotype was predictive for TTP and OS. CONCLUSION: Both S-1 and capecitabine were active and tolerable for elderly MGC patients. The CYP2A6 genotyping might guide treatment selection. PMID- 29189589 TI - Pediatric Emergency Research Canada: Origins and Evolution. AB - OBJECTIVE: The objective of the study was to describe the origins, growth, and progress of a national research network in pediatric emergency medicine. METHODS: The success of Pediatric Emergency Research Canada (PERC) is described in terms of advancing the pediatric emergency medicine agenda, grant funding, peer reviewed publications, mentoring new investigators, and global collaborations. RESULTS: Since 1995, clinicians and investigators within PERC have grown the network to 15 active tertiary pediatric emergency medicine sites across Canada. Investigators have advanced the research agenda in numerous areas, including gastroenteritis, bronchiolitis, croup, head injury, asthma, and injury management. Since the first PERC Annual Scientific meeting in 2004, the attendance has increased by approximately 400% to 152 attendees, 65 presentations, and 13 project/investigator meetings. More than $33 million in grant funding has been awarded to the network, and has published 76 peer-reviewed articles. In 2011, PERC's success was recognized with a Top Achievement Award in Health Research from Canadian Institutes of Health Research and the Canadian Medical Association Journal. CONCLUSIONS: Moving forward, PERC will continue to focus on the creation of new knowledge, the mentorship of new investigators and fellows in developing research projects, and promoting a pediatric emergency medicine-focused research agenda guided by the pooling of expertise from individuals across the nation. Through collaborations with networks across the globe, PERC will continue to strive for the conduct of high-quality, impactful research that improves outcomes in children with acute illness and injury. PMID- 29189590 TI - Management of Pediatric Isolated Skull Fractures: A Decision Tree and Cost Analysis on Emergency Department Disposition Strategies. AB - OBJECTIVE: Pediatric isolated skull fractures (ISFs) are common injuries that represent challenging disposition decisions for clinicians. The purpose of this study is to use a decision analysis to compare the clinical and cost effectiveness of 3 emergency department (ED)-based disposition scenarios for a pediatric patient presenting with ISF. METHODS: We conducted a cost-effectiveness analysis comparing ED disposition scenarios that included current practice, increased at-home surveillance, and observation unit utilization. Current rates of admission, deterioration after initial diagnosis, and ED return after discharge, as well as cost of observation-only status, were obtained through literature review. Cost calculations using Healthcare Cost and Utilization Project data included total ED cost, admission without complication, and admission with deterioration. RESULTS: In current practice, 76% of subjects with ISF are admitted and 2.5% of those develop persistent or new symptoms. No patient diagnosed with ISF required neurosurgical intervention. Of those discharged home from the ED, 2.8% return with a new concern with 7.4% having new findings on imaging leading to admission. Total cost per 100 patients by current practice was US $583,587. Increasing at-home surveillance by 20% resulted in a total cost saving of US $113,176 per 100 patients while increasing returns to the ED from less than 1% to 1.1%. Admitting at the current rate to an observation unit resulted in a US $205,395 cost saving per 100 patients. CONCLUSIONS: Decreased inpatient utilization through home surveillance or observation unit use reduced cost associated with pediatric ISF management without increasing clinical risk owing to the low probability of clinical deterioration after initial diagnosis. PMID- 29189591 TI - Luc's Abscess and Temporomandibular Joint Septic Arthritis: Two Rare Sequelae of Acute Otitis Media. AB - A 5-year-old previously healthy child presented with right-sided otalgia, right facial and temporal swelling, and right jaw pain in the setting of 6 days of low grade fever. The child had no trauma, vomiting, or prior dental treatments. On physical examination, the patient had facial swelling, erythema, and tenderness over the right temporal region along with trismus, as well as pain on palpation of the right temporomandibular joint (TMJ). A computed tomography scan revealed otitis media, Luc's abscess, and TMJ septic arthritis requiring surgical drainage and intravenous antibiotics. The patient responded well to treatment and recovered without sequelae. Dr. Cardwell Luc first described Luc's abscess in 1913 as a rare complication of middle ear infection leading to an abscess in the infratemporal space. To our knowledge, our case is the first documented case of concurrent Luc's abscess and TMJ septic arthritis in a previously healthy child as complications of acute otitis media. This case highlights 2 rare complications of a common medical condition that pediatric emergency care providers should recognize due to the need for surgical intervention, without which there may be longstanding sequelae. PMID- 29189592 TI - Early Reduction of Pediatric Traumatic Posterior Hip Dislocation Is Much More Important Than the Treatment Procedure. AB - Traumatic hip dislocations are very rare in the pediatric population, and they are real emergent cases that can occur with minimal trauma. If they are not diagnosed immediately and reduction is not performed as soon as possible, they may cause problems such as avascular necrosis and degenerative arthritis. Performing reduction within the first 6 hours is of vital importance.We aim to present the functional outcomes and radiographic results of 2 pediatric traumatic hip dislocation cases with 36 months of follow-up who were treated with abduction orthosis after the reduction. We want to emphasize the importance of reduction time in the outcome of posterior traumatic hip dislocations followed with abduction orthesis even if there is a trend and suggestion to treat these patients with spica cast with the review of the recent literature. PMID- 29189593 TI - Association of Insurance With Use of Emergency Medical Services Among Children. AB - OBJECTIVE: The use of emergency medical services (EMS) can be lifesaving for critically ill children and should be defined by the child's clinical need. Our objective was to determine whether nonclinical demographic factors and insurance status are associated with EMS use among children presenting to the emergency department (ED). METHODS: In this cross-sectional study using the National Hospital Ambulatory Medical Care Survey, we included children presenting to EDs from 2009 to 2014. We evaluated the association between EMS use and patients' insurance status using multivariable logistic regressions, adjusting for demographic, socioeconomic, and clinical factors such as illness severity as measured by a modified and recalibrated version of the Revised Pediatric Emergency Assessment Tool (mRePEAT) and the presence of comorbidities or chronic conditions. A propensity score analysis was performed to validate our findings. RESULTS: Of the estimated 191,299,454 children presenting to EDs, 11,178,576 (5.8%) arrived by EMS and 171,145,895 (89.5%) arrived by other means. Children arriving by EMS were more ill [mRePEAT score, 1.13; 95% confidence interval (CI), 1.12-1.14 vs mRePEAT score, 1.01; 95% CI: 1.01-1.02] and more likely to have a comorbidity or chronic condition (OR: 3.17, 95% CI: 2.80-3.59). In the adjusted analyses, the odds of EMS use were higher for uninsured children and lower for children with public insurance compared with children with private insurance [OR (95% CI): uninsured, 1.41 (1.12-1.78); public, 0.77 (0.65-0.90)]. The propensity score analysis showed similar results. CONCLUSIONS: In contrast to adult patients, children with public insurance are less likely to use EMS than children with private insurance, even after adjustment for illness severity and other confounders. PMID- 29189594 TI - Unusual Case of Penile Ecchymosis. AB - Hirudin is a potent anticoagulant found in the salivary glands of several species of leeches. We report a case of direct hirudin exposure after suspected leech bite causing significant penile ecchymosis. Diagnosis was not apparent on initial evaluation but made after a thorough history was obtained and the leech was found in the lining of his swim trunks, which he left at home. Although this presentation mimics several other potentially serious conditions, treatment is largely observational with anticipated rapid improvement over the course of hours without intervention. PMID- 29189595 TI - Fast and Sensitive: Automated Point-of-Care Urine Dips. AB - OBJECTIVE: Point-of-care (POC) urine dipstick is a highly used test in the pediatric emergency department (PED) owing to its fast turn-around time and inexpensive cost. Past studies have shown hand-held urine dipsticks and automated urinalysis in children younger than 48 months to be sensitive predictors for urinary tract infection (UTI). It is hypothesized that POC dip testing is as accurate as laboratory urinalysis in the diagnosis of UTI. METHODS: A retrospective chart review was conducted on patients (aged birth through 18 years) presenting to a PED between January 2015 and December 2015. Eligible subjects included those that had a POC dip, laboratory urinalysis (lab UA), and urine culture performed during their PED visit. Subjects were selected, using a random number generator; 334 charts were selected. A positive POC dip was defined as having a positive leukocyte esterase or the presence of nitrites. A positive lab UA was defined as having a positive leukocyte esterase, nitrites, or greater than 10 white blood cells per high-power field. Urine culture was used as the criterion standard for comparison. RESULTS: A total of 334 subjects' charts were reviewed. Sensitivity and specificity of the POC dip were 91.4% (95% confidence interval [CI], 76.9%-98.2%) and 63.9% (95% CI, 57.2%-69.3%); lab UA, 91.4% (95% CI, 76.9%-98.2%) and 63.9% (95% CI, 58.2%-69.3%); and lab dip, 88.6% (95% CI, 73.3%-96.8%) and 65.6% (95% CI, 59.9%-70.9%). CONCLUSIONS: Point-of-care dips are as sensitive in detecting UTI as the lab UA. A prospective study could allow for further demographic evaluation of POC dip diagnosed UTI. PMID- 29189596 TI - Procedural Training and Assessment for Pediatric Emergency Medicine Physicians Within the United States and Canada: A Survey Study. AB - OBJECTIVES: The aims of this study were to determine current practices in procedural training and skill assessment for attending physicians working in pediatric emergency departments within the United States and Canada and identify barriers to providing training and assessment. METHODS: This was a cross sectional survey study. Members of the pediatric emergency medicine fellowship program directors and associate program directors Listserv were invited to participate in an anonymous survey about attending physician training and assessment practices for 9 specific procedures and barriers to training and assessment. RESULTS: Eighty-two (56.2%) of 146 recipients responded, with 79 surveys fully completed; 58.5% of responders report that their division offers procedural training, whereas 14.6% report assessment of procedural skills. The most common procedure for which participants report training and assessment is orotracheal intubation (53.1% and 7.5%, respectively), with training rates for other procedures ranging from 2.5% to 43.0%. Most sites that report training use simulation in some form for education. For assessment, simulation is used almost exclusively. Cost (50.6%), lack of faculty interest (36.7%), and lack of standardized guidelines (36.7%) are the most common barriers to training. Lack of standardized guidelines (51.9%), cost (43.0%), and lack of faculty interest (38.0%) are the most common barriers for assessment. CONCLUSIONS: Although pediatric emergency medicine physicians may be required to perform emergent procedures, opportunities to receive training and assessment in these procedures are limited. Simulation and other educational modalities are being used to provide skill training and assessment, but cost and lack of resources, standardized protocols, and faculty interest are barriers to the implementation of training and assessment programs. PMID- 29189597 TI - Ultrasonic Percutaneous Tenotomy of Common Extensor Tendons for Recalcitrant Lateral Epicondylitis. AB - Tennis elbow is a common musculoskeletal condition affecting middle-aged patients with symptoms usually lasting from 6 months to 2 years. The vast majority of individuals will respond to conservative therapy; however, some will require surgical intervention. A new treatment system has been developed for use with ultrasound guidance in the ultrasonic microresection of tendinopathic tissue. This technology has been implemented in the TX1 Tissue Removal System and is used to treat various tendinopathies by debridement using targeted ultrasonic energy. We describe the surgical technique for the TX1 system as well as provide pain and functional outcome scores for a series of patients with recalcitrant lateral epicondylitis treated with percutaneous tenotomy with ultrasonic energy utilizing ultrasound guidance. PMID- 29189598 TI - Comparison of Psychiatric Symptoms in Patients With Obstructive Sleep Apnea, Simple Snoring, and Normal Controls. AB - OBJECTIVE: Patients with sleep-related breathing disorders are known to have more severe psychiatric symptoms than good sleepers. The aim of this study was to compare the psychiatric symptoms of participants with obstructive sleep apnea (OSA), those with simple snoring (SS), and normal controls (NC). METHODS: A total of 386 participants (260 with OSA, 75 with SS, and 51 NC) completed self-report questionnaires including the Symptoms Checklist 90-Revised and underwent nocturnal polysomnography. The scores of nine primary symptom dimensions and three global distress indices of the Symptoms Checklist 90-Revised were compared among the three groups, adjusting for age, sex, and body mass index. RESULTS: Participants with suspected OSA (OSA + SS) reported more severe psychiatric symptoms than the NC group. Compared with the participants with OSA, those with SS manifested more severe obsessive-compulsive (1.4 (1.0) versus 1.1 (0.7), p = .008) and depressive (1.2 (1.2) versus 0.8 (0.8), p = .031) symptoms and higher Global Severity Index (1.0 (0.9) versus 0.7 (0.6), p = .039) and Positive Symptom Distress Index (2.0 (0.8) versus 1.7 (0.6), p = .009). Only higher Pittsburgh Sleep Quality Index values predicted higher Global Severity Index (B = 0.11, p = .041) and Positive Symptom Distress Index (B = 0.46, p = .007) in suspected OSA participants. CONCLUSIONS: This study found that individuals with suspected OSA experienced more severe psychiatric symptoms than NCs and that psychiatric symptoms were more severe in the SS group than in the OSA group. The psychiatric symptoms of suspected OSA patients were associated with subjective sleep quality rather than with the apnea-hypopnea index. PMID- 29189599 TI - Local estrogen benefits of postmenopausal women with dyspareunia: data confirming what clinicians already know! PMID- 29189600 TI - Pharmacoeconomic and associated cost savings among women who were prescribed systemic conjugated estrogens therapy compared with those without menopausal therapy. AB - OBJECTIVE: To explore changes in healthcare costs among postmenopausal women in a commercial population who were prescribed conjugated estrogens for menopausal symptoms. METHODS: Using the MarketScan dataset from April 1, 2008 through September 30, 2012, postmenopausal women aged >=45 years, who were prescribed conjugated estrogen tablets (Premarin), were identified. A comparative cohort of postmenopausal women with vasomotor symptoms without any menopause therapy was also identified. Women included were required to have continuous medical and pharmacy benefits for 6 months before and 12 months after index date, with baseline characteristics compared using chi-square and t tests. The 6 and 12 month change (difference in follow-up and baseline costs) in direct healthcare costs was calculated and a difference-in-differences model was used to compare the incremental change at 6 and 12 months in healthcare costs between the cohorts, adjusting for demographic and clinical characteristics. RESULTS: The study included 1,404 women who were prescribed conjugated estrogens, and 3,096 untreated women. Women prescribed conjugated estrogens were significantly younger (52 vs 54 years; P < 0.0001) and had a lower Charlson comorbidity index score (0.29 vs 0.41; P < 0.001) compared with the untreated women. After adjusting for baseline characteristics, women treated with conjugated estrogens showed a greater difference in the change in total healthcare costs (-$1,601 vs -$503; P = 0.044), including inpatient stay costs (-$1,431 vs -$28; P < 0.0001), between the baseline and follow-up periods compared with untreated women. CONCLUSIONS: Women who were prescribed oral conjugated estrogens had a significantly greater reduction in healthcare costs after treatment initiation compared with untreated postmenopausal women.

PMID- 29189604 TI - 2017 Military Supplement to Shock Journal PerftoranTM (VidaphorTM) - Introduction to Western Medicine. AB - Perftoran, which has been re-branded as Vidaphorfor marketing in North America, is an emulsion of perfluorocarbons in a surfactant and electrolyte mixture. It was developed in Russia as an oxygen-carrying intravenous plasma additive for hemorrhagic anemia and ischemic conditions from various etiologies. It was approved for clinical use in Russia in 1996 and used by the Russian Armed Forces and in civilian medical care. It was also approved in Mexico from 2005 to 2010. It has been reportedly administered to over 35,000 patients with significant evidence of benefit and relatively mild and manageable adverse effects. It may have significant potential for use in hemorrhagic shock if human red blood cells are not available, and for several other applications including treatment of vascular gas embolism, cerebral or spinal trauma, and regional ischemia. It is different from other perfluorocarbon preparations under development in the USA in that is uses a different primary perfluorocarbon (perfluorodecalin) and a surfactant (Proxanol 268) instead of egg-yok phospholipid as the emulsion vehicle. Perftoran has a much smaller particle size resulting in milder adverse effects. It has been safely administered to more patients than any oxygen carrier currently under development. A newly formed United States Corporation (FluorO2 Therapeutics, Inc.) intends to manufacture the product in the United States under GMP standards and make it available for clinical use in Mexico and Latin America and pursue research to support eventual approval in the USA for human and veterinary use. This article will briefly review key information about this product and provide references for the interested reader. PMID- 29189603 TI - The dynamics of stress and fatigue across menopause: attractors, coupling, and resilience. AB - OBJECTIVE: The objective of this study was to evaluate the regulatory dynamics between stress and fatigue experienced by women during the menopausal transition (MT) and early postmenopause (EPM). Fatigue and perceived stress are commonly experienced by women during the MT and EPM. We sought to discover relationships between these symptoms and to employ these symptoms as possible markers for resilience. METHODS: Participants were drawn from the longitudinal Seattle Midlife Women's Health Study. Eligible women completed questionnaires on 60+ occasions (annual health reports and monthly health diaries) (n = 56 women). The total number of observations across the sample was 4,224. STRAW+10 criteria were used to stage women in either in late reproductive, early or late transition, or EPM stage. Change values were generated for fatigue and stress and analyzed with a multilevel structural equation model; slopes indicate how quickly a person returns to homeostasis after a perturbation. Coupling of stress and fatigue was modeled to evaluate resilience, the notion of maintaining stability during change. RESULTS: Eligible women were on average 35 years old (SD = 4.71), well educated, employed, married or partnered, and white. Fit indices suggested the model depicts the relationships of stress and fatigue (chi(9 df) = 7.638, P = 0.57, correction factor = 4.9244; root mean square error of approximation (RMSEA) 90% CI = 0.000 <= 0.000 <= 0.032; comparative fit index (CFI) = 1.00). A loss in model fit across stages suggests that the four stages differed in their dynamics (chiDelta(12 df) = 21.181, P = .048). All stages showed fixed-point attractor dynamics: fatigue became less stable over time; stress generally became more stable over time. Coupling relationships of stress on fatigue show evidence for shifts in regulatory relationships with one another across the MT. CONCLUSIONS: Results are suggestive of general dysregulation via disruptions to coupling relationships of stress and fatigue across the MT. Findings support a holistic approach to understanding symptoms and supporting women during the MT. PMID- 29189605 TI - Involvement of Aromatic Metabolites in the Pathogenesis of Septic Shock. AB - INTRODUCTION: We hypothesized that aromatic microbial metabolites (AMM), such as phenyllactic (PhLA), p-hydroxyphenylacetic (p-HPhAA), and p-hydroxyphenyllactic (p-HPhLA) acids, contribute to the pathogenesis of septic shock. METHODS: Clinical and laboratory data of patients with community-acquired pneumonia were obtained on intensive care unit admission and the next day. Patients were divided into two groups based on septic shock presence or absence. The levels of AMM (PhLA, p-HPhAA, p-HPhLA, and their sum, ?3AMM), catecholamine metabolites (3,4 dihydroxymandelic [DHMA], 3,4-dihydroxyphenylacetic [DOPAC], and homovanillic [HVA] acids), lactate, N-terminal pro-brain natriuretic peptide (NT-proBNP), inducible nitric oxide synthase (iNOS), and procalcitonin (PCT) were compared. Correlations between AMM and clinical and laboratory data were calculated. RESULTS: There were 20 patients in the septic shock group and 21 in the nonseptic shock group. On admission, the septic shock patients demonstrated significantly higher levels of PhLA (2.3 vs. 0.8 MUmol/L), p-HPhAA (4.6 vs. 1.4 MUmol/L), p HPhLA (7.4 vs. 2.6 MUmol/L), HVA, lactate, and significantly lower levels of iNOS. The next day, the two groups also showed significant differences in the levels of PCT and NT-proBNP. The correlation between ?3AMM and presence of shock, levels of lactate, HVA, and NT-proBNP on admission was 0.44, 0.67, 0.57, and 0.38, respectively, and the correlation on the next day was 0.59, 0.73, 0.76, and 0.6, respectively (P < 0.01). These findings can be explained by the ability of AMM to reduce tyrosine hydroxylase activity, thus limiting the synthesis of catecholamines. CONCLUSIONS: AMM are involved in the pathogenesis of septic shock. PMID- 29189606 TI - Moyamoya Syndrome in a Child With HIV-1 Infection. AB - Neurologic manifestations of HIV infection are not uncommon. However, stroke secondary to Moyamoya syndrome has rarely been described in children with HIV infection. We report a 10-year-old boy with perinatally acquired HIV-1 infection, who presented with recurrent strokes while on antiretroviral therapy. PMID- 29189607 TI - Effect of Oral Probiotic Streptococcus salivarius K12 on Group A Streptococcus Pharyngitis: A Pragmatic Trial in Schools. AB - BACKGROUND: The aim of this study was to examine effectiveness of oral probiotic Streptococcus salivarius K12 in preventing group A streptococcus pharyngitis in 5 to 14-year-old children at high risk of acute rheumatic fever. New Zealand has high rates of acute rheumatic fever among Maori and Pacific children. Children were already enrolled in a school-based Ministry of Health throat swabbing and treatment program. Children self-identified and reported sore throats daily and were swabbed twice weekly. METHODS: A total of 1314 children were quasirandomized (based on odd or even birthdates) to receive either K12 (2.5 * 10 cfu per lozenge) or placebo lozenges and continued observed daily treatment (in the school week, during school time) for one school year. RESULTS: A total of 801 children (61.0%) reported a sore throat on one or more occasions resulting in 2927 pharyngeal swabs. Of these swabs, 1525 (52.1%) were taken from 411 children receiving K12 and 119 (7.8%) of these were positive for group A streptococcus on routine culture. In addition, 1402 (47.8%) swabs were taken from 390 children receiving placebo and 124 (8.8%) were positive. Overall there was a nonsignificant 11.2% relative reduction in positive swabs among children receiving K12. This relative reduction was greater for older children, 7-9 years of age, 15.6%, and for children 10 years and older, 30.2%. CONCLUSIONS: S. salivarius K12 had modest nonsignificant effects on culture-positive sore throats when given at school, during the school day. Based on our pragmatic trial, the routine use of this probiotic in the prevention of pharyngitis associated with GAS detection is not supported. PMID- 29189608 TI - Race, Income and Insurance Status Affect Neonatal Sepsis Mortality and Healthcare Resource Utilization. AB - BACKGROUND: Socioeconomic disparities negatively impact neonatal health. The influence of sociodemographic disparities on neonatal sepsis is understudied. We examined the association of insurance payer status, income, race and gender on neonatal sepsis mortality and healthcare resource utilization. METHODS: We used the Kid's Inpatient Database, a nationwide population-based survey from 2006, 2009 and 2012. Neonates diagnosed with sepsis were included in the study. Multivariable logistic regression (mortality) and multivariable linear regression (length of stay and total hospital costs) were constructed to determine the association of patient and hospital characteristics. RESULTS: Our study cohort included a weighted sample of 160,677 septic neonates. Several sociodemographic disparities significantly increased mortality. Self-pay patients had increased mortality (odds ratio 3.26 [95% confidence interval: 2.60-4.08]), decreased length of stay (-2.49 +/- 0.31 days, P < 0.0001) and total cost (-$5015.50 +/- 783.15, P < 0.0001) compared with privately insured neonates. Additionally, low household income increased odds of death compared with the most affluent households (odds ratio 1.19 [95% confidence interval: 1.05-1.35]). Moreover, Black neonates had significantly decreased length of stay (-0.86 +/- 0.25, P = 0.0005) compared with White neonates. CONCLUSIONS: This study identified specific socioeconomic disparities that increased odds of death and increased healthcare resource utilization. Moreover, this study provides specific societal targets to address to reduce neonatal sepsis mortality in the United States. PMID- 29189610 TI - Early Childhood Neurodevelopmental Outcomes in Infants Exposed to Infectious Syphilis In Utero. AB - BACKGROUND: There are minimal neurodevelopmental follow-up data for infants exposed to syphilis in utero. METHODS: This is an inception cohort study of infants exposed to syphilis in utero. We reviewed women with reactive syphilis serology in pregnancy or at delivery in Edmonton (Canada), 2002 through 2010 and describe the neurodevelopmental outcomes of children with and without congenital syphilis. RESULTS: There were 39 births to women with reactive syphilis serology, 9 of whom had late latent syphilis (n = 4), stillbirths (n = 2) or early neonatal deaths (n = 3), leaving 30 survivors of which 11 with and 7 without congenital syphilis had neurodevelopmental assessment. Those with congenital syphilis were all born to women with inadequate syphilis treatment before delivery. Neurodevelopmental impairment was documented in 3 of 11 (27%) infants with congenital syphilis and one of 7 (14%) without congenital syphilis with speech language delays in 4 of 11 (36%) with congenital syphilis and 3 of 7 (42%) without congenital syphilis. CONCLUSIONS: Infants born to mothers with reactive syphilis serology during pregnancy are at high risk for neurodevelopmental impairment, whether or not they have congenital syphilis, so should all be offered neurodevelopmental assessments and early referral for services as required. PMID- 29189609 TI - Introduction of Routine HIV Birth Testing in the South African National Consolidated Guidelines. AB - BACKGROUND: South Africa represents the first high-burden setting to introduce routine virologic testing at birth within its early infant diagnosis program, implemented in June 2015. National HIV birth testing coverage, intrauterine transmission rates and case rates for the first year since introduction of universal birth testing are reported. METHODS: HIV polymerase chain reaction (PCR) test data from June 2015 to May 2016 were extracted from the National Health Laboratory Service's central data repository by year, month, age, result and geographic location. Birth testing was defined as all HIV PCR tests performed at <7 days of life; coverage as the proportion of all HIV-exposed neonates born who were tested at birth; estimated intrauterine transmission rate as the percentage of HIV PCR positive tests in HIV-exposed neonates tested and case rates as the number of HIV PCR positive tests per 100,000 total live births. RESULTS: Between June 2015 and May 2016, the South African national monthly birth testing coverage increased from 39% (8636 tests) to 93% (20,479 tests). During this period, the number of positive tests at birth increased from 114 to 234 per month, equating to a national intrauterine transmission rate of 1.1% and a birth case rate of 247 per 100,000 live births. CONCLUSIONS: Universal birth testing for all HIV-exposed neonates is rapidly being achieved in South Africa, facilitating earlier detection of intrauterine infected neonates. However, the successful linkage into care of HIV-infected neonates and their treatment outcomes remain to be assessed. PMID- 29189611 TI - Treatment of Acute Otitis Media in the Pediatric Emergency Department. AB - BACKGROUND: Over-treatment of acute otitis media (AOM) with antibiotics is common, and poses a high burden on health-care systems. METHODS: Records of children 6-36 months of age with AOM visiting a university-affiliated pediatric emergency department between 2014 and 2016 were reviewed for the treatment given: watchful waiting versus antibiotics. If antibiotics were prescribed, the type and duration were recorded. We evaluated appropriate and inappropriate treatment rates of eligible AOM cases, in respect to the local guidelines, which encourage watchful waiting in most mild-moderate cases. RESULTS: Out of 1493 AOM visits, 863 (57.8%) were boys, with a median age of 14.9 months (interquartile range, 9 19). The overall pre-visit antibiotic rate was 24.1%, but among those children examined by a physician, this rate was 95.2%. Amoxicillin was the most common antibiotic, administered in 66.3% of the cases. Only 21 children (5.8%) had been treated with antibiotics for >=7 days before their visit, and were considered as treatment failure. Antibiotic therapy upon discharge was recorded in 1394/1449 visits (96.2%), again with amoxicillin as the most common antibiotic therapy, in 80.8% of the cases. In these visits, the average duration of antibiotic treatment was 8.29 days. Appropriateness of treatment (watchful waiting or antibiotics) could be analyzed in 1134 visits; 20.9% were considered as inappropriate. Of them, 98.3% were prescribed with the wrong antibiotic type and duration. CONCLUSIONS: Adherence rate to the local guidelines treatment recommendations for uncomplicated AOM was high, as measured by whether appropriate treatment was given and type and duration of antibiotics.

PMID- 29189612 TI - Evaluation of the Influence of Gastrointestinal Coinfections on Rotavirus Vaccine Effectiveness in Botswana. AB - BACKGROUND: Studies have demonstrated reduced rotavirus vaccine effectiveness (VE) in resource-limited settings. Enteropathogen coinfections in rotavirus cases have been hypothesized to contribute to the lower VE in such settings. We sought to determine if coinfections affect rotavirus VE in Botswana. METHODS: Between June 2013 and April 2015, children <60 months old, presenting with severe gastroenteritis at 4 hospitals as part of a national rotavirus surveillance were enrolled. Rotavirus enzyme immunoassay (EIA)-positive samples were tested with an in-house real-time polymerase chain reaction (PCR) panel that detected 9 pathogens and a commercial 15 multiplex PCR gastrointestinal pathogen panel. Coinfection was defined as detection of rotavirus plus 1 of the 5 pathogens with the highest attributable fractions for diarrhea. Vaccine status was compared between rotavirus case patients and non-rotavirus "test-negative" controls. VE was also calculated restricting cases to those with rotavirus as the only pathogen detected. RESULTS: Two hundred and forty-two children tested rotavirus EIA positive, and 368 children were negative. Of the 182 rotavirus EIA-positive samples tested with the gastrointestinal pathogen panel assay, coinfections were detected in 60 (33%). The overall adjusted 2-dose VE was 59% (95% confidence interval [CI]: 27-77) in the rotavirus coinfection group and 51% (95% CI: -14 to 79) in the rotavirus monoinfection subgroup. Using in-house multiplex PCR panel, of 213 rotavirus EIA-positive subjects, coinfections were detected in 98 samples (46%). The overall adjusted VEs for 2 doses were 48% (95% CI: -2 to 74) and 62% (95% CI: 25-80) in rotavirus monoinfection subgroup. CONCLUSIONS: We could not find evidence of an effect of enteric coinfections on the effectiveness of rotavirus vaccine. PMID- 29189614 TI - Acquired Infection and Antimicrobial Utilization During Initial NICU Hospitalization in Infants With Congenital Diaphragmatic Hernia. AB - BACKGROUND: In addition to substantial medical and surgical intervention, neonates with congenital diaphragmatic hernia often have concurrent concerns for acquired infection. However, few studies focus on infection and corresponding antimicrobial utilization in this population. METHODS: The Children's Hospital Neonatal Database was queried for congenital diaphragmatic hernia infants hospitalized from January 2010 to February 2016. Patient charts were linked to the Pediatric Health Information Systems database. Descriptive clinical data including delivery history, cultures sent, diagnosed infection, antimicrobial use and outcomes were reported. RESULTS: A total of 1085 unique patients were identified after data linkages; 275 (25.3%) were born at <37 weeks' gestation. Bacteremia at delivery (2/1085) and in the first 7 days of life (8/1085) was less common than later infection, but 976 patients (89.9%) were treated with antibiotics. Median number of days on antibiotics was 6 [3,11] for those without a documented infection and 21 [13,36] for those with positive cultures. Incidence of urinary tract infection, bacteremia and pneumonia increased significantly over time and was most common after 28 days. Antibiotic use, conversely, decreased over time (92% of infants in week 1 to 44% in week 4 and beyond). CONCLUSIONS: Although culture positivity increased with age, risk of these selected infections was relatively low for a population in neonatal intensive care unit. An important mismatch is observed between culture negativity and high rates of antibiotic utilization. These data identify opportunities for antibiotic stewardship quality improvement programs. PMID- 29189615 TI - Multimodal Treatment of Rhinocerebral Mucormycosis in a Pediatric Patient With Relapsed Pre-B Acute Lymphoblastic Leukemia. AB - A 17-year-old girl developed invasive rhinocerebral mucormycosis during intensive re-induction chemotherapy for relapsed pre-B acute lymphoblastic leukemia. Due to the high case fatality rate for invasive mucormycosis in profoundly immunosuppressed patients, an aggressive treatment regimen was pursued. In addition to the standard of care treatments with intravenous amphotericin and aggressive surgical debridements, she received intraventricular amphotericin to the brain via an Ommaya reservoir, hyperbaric oxygen treatments, filgrastim, intravenous immunoglobulin and antifungal in vitro synergy testing to allow for more targeted antifungal therapy with the addition of micafungin. After a 3-month treatment course, it was determined that her mucormycosis was under appropriate control, allowing her to continue treatment for her leukemia with hematopoietic stem cell transplant with a plan for continued intravenous antifungal therapy through engraftment.

AB - The knee is the most complex and largest joint in the body. Injuries to any part of this joint affect the entire body. There are multiple injuries that can occur to the knee, with the most common being ligament and meniscus tears. A not-so common injury to the knee is a patellar tendon rupture. A bilateral patellar tendon rupture is extremely rare. A case study of a 43-year-old man who sustained a bilateral patellar tendon rupture while playing softball is used to present this devastating injury. This discussion includes the incidence and diagnosis of the tear, surgical repair, as well as a description of the comprehensive rehabilitation process necessary to allow the patient to return to normal physical activity. Risks and complications of this surgery and the expected outcomes are also presented. PMID- 29189619 TI - Bilateral Patellar Tendon Rupture. PMID- 29189620 TI - Nurse Practitioner Fracture Liaison Role: A Concept Analysis. AB - BACKGROUND: With the worldwide growing aging population, the high prevalence of osteoporosis-related fractures is associated with high morbidity and mortality. Healthcare costs for treating fractures and subsequent complications will increase to $25 billion by 2025. PURPOSE: This article articulates a comprehensive concept analysis of the nurse practitioner fracture liaison (NPFL) role to provide new insights into the role of nurse practitioner in osteoporosis care coordination. METHODS: Walker and Avant's concept analysis framework was used to identify the attributes, antecedents, consequences, and empirical referents of the NPFL role. Model cases illustrated real-life examples of the NPFL role. CONCLUSION: The impact of NPFL role is rather novel in promoting healthy bone living at local, national, and international communities. Linking the refined outcome of the concept analysis of the NPFL role to osteoporosis care helps close osteoporosis care gaps, improve healthcare outcomes, and alleviate financial burden by reducing secondary fracture and complications. PMID- 29189622 TI - Predictors of Nurses' Intentions to Administer As-Needed Opioid Analgesics for Pain Relief to Postoperative Orthopedic Patients in the Acute Care Setting. PMID- 29189621 TI - Predictors of Nurses' Intentions to Administer As-Needed Opioid Analgesics for Pain Relief to Postoperative Orthopaedic Patients in the Acute Care Setting. AB - BACKGROUND: Patients undergoing orthopaedic surgery experience severe postoperative pain that is frequently undertreated. No study was found that examined the predictors of nurses' intentions to administer as needed (PRN) opioid analgesics for postoperative pain relief. PURPOSE: The purpose of this study was to determine what constructs from the Integrated Behavioral Model (IBM) can predict nurses' intentions to administer PRN opioid analgesics for pain relief to hospitalized postoperative orthopaedic patients. METHODS: A nonexperimental, cross-sectional quantitative format was used. The sample consisted of 800 nurses. Data collection was done by survey. RESULTS: Path analysis revealed the significant predictors of nurses' intention to administer opioid analgesics to be self-efficacy (beta= 0.15), normative beliefs (beta= 0.21), and salience (importance) of the behavior (beta= 0.25). CONCLUSION: The study showed that the IBM constructs are useful for predicting intentions toward performance of a professional behavior. The inclusion of self-efficacy, underlying beliefs, and salience of the behavior was new and unique contributions to the existing body of knowledge. PMID- 29189624 TI - Preoperative Risk Factors for Subsyndromal Delirium in Older Adults Who Undergo Joint Replacement Surgery. PMID- 29189625 TI - Adolescents' Experiences of Scoliosis Surgery and the Trajectory of Self-Reported Pain: A Mixed-Methods Study. AB - Scoliosis surgery for adolescents is a major surgery with a difficult recovery. In this study, a mixed-methods design was used to broaden the scope of adolescents' experiences of surgery for idiopathic scoliosis and the trajectory of self-reported pain during the hospital stay and through the first 6 months of recovery at home. Self-reports of pain, diaries, and interviews were analyzed separately. The results were then integrated with each other. The trajectory of self-reported pain varied hugely between individuals. Adolescents experienced physical suffering and struggled to not be overwhelmed. The adolescents described the environmental and supportive factors that enabled them to cope and how they hovered between suffering and control as they strived toward normality. This study highlights areas of potential improvement in perioperative scoliosis care in terms of nursing support and pain management. PMID- 29189623 TI - Preoperative Risk Factors for Subsyndromal Delirium in Older Adults Who Undergo Joint Replacement Surgery. AB - BACKGROUND: Older adults with subsyndromal delirium have similar risks for adverse outcomes following joint replacement surgery as those who suffer from delirium. PURPOSE: This study examined relationships among subsyndromal delirium and select preoperative risk factors in older adults following major orthopaedic surgery. METHODS: Delirium assessments of a sample of 62 adults 65 years of age or older were completed on postoperative Days 1, 2, and 3 following joint replacement surgery. Data were analyzed for relationships among delirium symptoms and the following preoperative risk factors: increased comorbidity burden, cognitive impairment, fall history, and preoperative fasting time. RESULTS: Postoperative subsyndromal delirium occurred in 68% of study participants. A recent fall history and a longer preoperative fasting time were associated with delirium symptoms (p <= .05). CONCLUSIONS: Older adults with a recent history of falls within the past 6 months or a longer duration of preoperative fasting time may be at higher risk for delirium symptoms following joint replacement surgery. PMID- 29189626 TI - Organizational Learning in an Orthopaedic Unit: A Learning History. AB - The purpose of this study was to explore organizational learning in an orthopaedic hospital unit. Skill in organizational learning is necessary to achieve high reliability in a dynamic healthcare environment, yet organizational learning in hospital units is not well understood. A learning history was conducted with a high-performing orthopaedic unit. Findings were interpreted in the context of a previous learning history conducted with a critical care unit. Despite contextual differences, each unit progressed through the same four developmental stages to achieve its current state of high reliability. On both units, psychological safety and a healthy work environment proved essential for developmental progression. Hospital units may progress through distinct developmental stages to achieve their desired outcomes. Psychological safety and a healthy work environment appear foundational to organizational learning in hospital units. Nursing leaders should work with team members to evaluate their unit's development and use suggested strategies to facilitate organizational learning. PMID- 29189628 TI - Screening for Posttraumatic Stress Disorder in Civilians With Mangled Hand Injury: A Practice Enhancement Approach. AB - Posttraumatic stress disorder (PTSD) is a symptom cluster of intrusion, avoidance, negative alteration in cognition, and alteration in arousal and reactivity following trauma. PTSD occurs frequently after a physical trauma such as a severe hand injury. It is often not recognized and consequently untreated. Previous research has shown that 10%-40% of civilian trauma survivors experience PTSD in the first 12 months after injury. There is great urgency to identify patients in the early stage of recovery from trauma, as PTSD becomes more difficult to treat in its chronic form. Mangling hand injuries are particularly disabling because they are an integral part of our social body image. We wanted to investigate the degree of PTSD screening and the follow-up-referral procedures in all mangled hand cases at the hand clinic of a large Northwestern Trauma Center. A retrospective medical record review was conducted from January to December 2012 using an existing PTSD screen with data from the electronic medical records. We found that 40% of the patients with mangled hand injury were classified as "at risk" according to our PTSD screening but only 22% of those cases were referred to rehabilitation psychiatry for further evaluation and treatment. The low rate of referral for PTSD after mangled hand injury was alarming. On the basis of this, we instituted a new screening protocol for all patients with mangled hand injury using the 4-item Primary Care-PTSD screening tool and provided an informational brochure on PTSD. The investigation led to a positive change in the practice environment and workflow of the clinic. We have not conducted any follow-up study as yet, but our goal is to screen all patients with mangled hand injury and refer all patients for psychiatric therapy who have positively answered 3 of the 4 screening questions.

PMID- 29189631 TI - Incidence and Risk Factors of Intracranial Hemorrhage in Liver Transplant Recipients. AB - BACKGROUND: Intracranial hemorrhage after liver transplantation is an infrequently reported complication but one which can have devastating consequences. METHODS: We performed a retrospective cross-sectional analysis of all liver transplants performed between January 2010 and June 2015 at a single high-volume institution using a prospectively maintained electronic database and query of the electronic medical record. Cases of intracranial hemorrhage were adjudicated as either spontaneous intraparenchymal hemorrhage(IPH) or extra-axial hemorrhage (EAH). Patients with confirmed intracranial hemorrhage were compared with all other liver transplant recipients. Risk factors were identified by univariate analysis and logistic regression models for IPH and EAH. RESULTS: Thirty-one (5.2%) of 595 liver transplant recipients developed an intracranial hemorrhage within 12 months of transplantation, 15 IPH and 16 EAH. The majority of intracranial hemorrhages were diagnosed within 1 month of transplantation. Eight (26%) intracranial hemorrhage patients died during hospitalization. Fourteen (45%) intracranial hemorrhage patients died within 1 year of transplantation and 1-year mortality was greater than in patients without intracranial hemorrhage (11.2%, P < 0.01). Female sex (adjusted odds ratio [OR], 3.291; 95% confidence interval [CI], 1.092-9.924; P = 0.034), higher pretransplant bilirubin (adjusted OR, 1.037; 95% CI, 1.006-1.070; P = 0.020), and greater increase in pretransplant to posttransplant systolic blood pressure (adjusted OR, 1.029; 95% CI, 1.006-1.052; P = 0.012) were associated with posttransplant IPH. Lower pretransplant serum fibrinogen level (adjusted OR, 0.988; 95% CI, 0.979-0.998; P = 0.017) was associated with posttransplant EAH. CONCLUSIONS: Postoperative blood pressure control and pretransplant fibrinogen levels may be modifiable risk factors for preventing posttransplant intracranial hemorrhage. PMID- 29189632 TI - End-of-Treatment Positron Emission Tomography After Uniform First-Line Therapy of B-Cell Posttransplant Lymphoproliferative Disorder Identifies Patients at Low Risk of Relapse in the Prospective German PTLD Registry. AB - BACKGROUND: Fluorine-18 fluorodeoxyglucose (18F-FDG)-positron emission tomography (PET) is a recommended standard in the staging and response assessment of 18F-FDG avid lymphoma. Posttransplant lymphoproliferative disorder (PTLD) can be detected by 18F-FDG-PET at diagnosis with high sensitivity and specificity. However, the role of response assessment by end-of-treatment (EOT) PET has only been addressed in small case series. METHODS: We performed a retrospective, multicenter study of 37 patients with CD20-positive PTLD after solid organ transplantation treated with uniform, up-to-date, first-line protocols in the prospective German PTLD registry who had received EOT 18F-FDG-PET between 2006 and 2014. Median follow-up was 5.0 years. Any nonphysiological 18F-FDG uptake (Deauville score greater 2) was interpreted as PET-positive. RESULTS: By computed tomography (CT) final staging, 18 of 37 patients had a complete response, 18 had a partial response and 1 patient had stable disease. EOT PET was negative in 24 of 37 patients and positive in 13 of 37 patients. The positive predictive value of EOT PET for PTLD relapse was 38%, and the negative predictive value was 92%. Time to progression (TTP) and progression-free-survival were significantly longer in the PET negative group (P = 0.019 and P = 0.013). In the 18 patients in a partial response by CT staging, we noted highly significant differences in overall survival (P = 0.001), time to progression (P = 0.007), and progression-free survival (P < 0.001) by EOT PET. CONCLUSIONS: Even without baseline imaging, EOT PET in PTLD identifies patients at low risk of relapse and offers clinically relevant information, particularly in patients in a partial remission by CT staging. PMID- 29189633 TI - Lung Transplantation as a Therapeutic Option in Acute Respiratory Distress Syndrome. AB - BACKGROUND: Lung transplantation (LTPL) is considered as a salvage therapeutic option in patients with end-stage lung disease. However, there is a lack of sufficient data on the use of LTPL in patients with acute respiratory distress syndrome (ARDS). Although there are few case reports on lung transplant for ARDS, no case series exists up to date. The aim of this study was to evaluate the clinical outcomes of patients with ARDS in accordance with the LTPL status. METHODS: Patients who had severe ARDS (PaO2/FiO2 ratio <= 100 mm Hg with positive end-expiratory pressure >= 5 cm H2O) and were listed for LTPL with no underlying end-stage lung disease were included in this single-center retrospective study. Demographic and clinical data of the patients were collected and analyzed. RESULTS: Fourteen patients were listed for LTPL due to severe ARDS. All patients received mechanical ventilation, and 12 (86%) patients underwent extracorporeal membrane oxygenation. Of the 9 patients who underwent LTPL, 8 (89%) survived, whereas only 1 (20%) patient out of those who did not receive LTPL survived. The median survival time of the patients who underwent LTPL was 1996 days (interquartile range [IQR], 872-2239), compared with 49 days (IQR, 872-2239) in patients who did not undergo LTPL. The median survival time after LTPL was 64 months (IQR, 28-72). The 3-year survival rate of the recipients was 78%. CONCLUSIONS: LTPL may be considered as a therapeutic option in a select group of patients with severe ARDS. However, the irreversibility of the patient's lung status should be considered. PMID- 29189634 TI - Alpha band frequency differences between low-trait and high-trait anxious individuals. AB - Trait anxiety has been shown to cause significant impairments on attentional tasks. Current research has identified alpha band frequency differences between low-trait and high-trait anxious individuals. Here, we further investigated the underlying alpha band frequency differences between low-trait and high-trait anxious individuals during their resting state and the completion of an inhibition executive functioning task. Using human participants and quantitative electroencephalographic recordings, we measured alpha band frequency in individuals both high and low in trait anxiety during their resting state, and while they completed an Eriksen Flanker Task. Results indicated that high-trait anxious individuals exhibit a desynchronization in alpha band frequency from a resting state to when they complete the Eriksen Flanker Task. This suggests that high-trait anxious individuals maintain fewer attentional resources at rest and must martial resources for task performance as compared with low-trait anxious individuals, who appear to maintain stable cognitive resources between rest and task performance. These findings add to the cognitive neuroscience literature surrounding the role of alpha band frequency in low-trait and high-trait anxious individuals. PMID- 29189635 TI - When the body becomes no more than the sum of its parts: the neural correlates of scrambled versus intact sexualized bodies. AB - Recent research found that configural information is less important for the processing of sexualized bodies than for the processing of nonsexualized bodies. The present investigation aims to expand these findings by directly manipulating configural versus analytic processing of sexualized and nonsexualized bodies. We posited that disrupting first-order relational information through scrambling should be associated with larger N170 amplitudes (scrambling effect) for nonsexualized bodies, whereas the scrambling manipulation should not modulate N170 amplitudes associated with sexualized bodies and objects. We presented images of scrambled versus intact sexualized bodies, nonsexualized bodies, and objects while the N170 was recorded. Consistent with our hypothesis, we found that the scrambling manipulation was associated with larger N170 amplitudes for nonsexualized bodies (i.e. scrambling effect), whereas no scrambling effect emerged for sexualized bodies and objects. This research is the first to show that sexualized bodies are processed analytically at a neural level. Implications for the literature in body perception and objectification will be discussed. PMID- 29189636 TI - Mitochondrial fusion and fission proteins and the recognition memory of imprinting in domestic chicks. AB - Visual imprinting is a learning process through which young, visually naive animals come to recognize a visual stimulus by being exposed to it (training) and subsequently approach the stimulus in preference to others. A large body of evidence indicates that a restricted part of the forebrain, the intermediate medial mesopallium (IMM), is a memory region for visual imprinting in the domestic chick. Previous studies have shown learning-related up-regulation of several mitochondrial proteins in the IMM 24 h after training. Learning-related increases in transcription factors involved in mitochondrial biogenesis were found without significant change in mitochondrial DNA copy number, but the issue of whether mitochondrial fusion or fission processes change with learning was unresolved. The present study enquired whether proteins involved in mitochondrial fusion and fission contribute to memory following imprinting. Tissue was sampled from the left and right IMM, and the left and right posterior pole of the nidopallium (a control brain region not involved in imprinting). The amounts of the following proteins were measured by Western immunoblotting 24 h after training: mitochondrial mitofusin-1 (MTF-1, as indicator of mitochondrial fusion), membrane dynamin-related protein-1 (DRP-1, as indicator of mitochondrial fission) and cytoplasmic DRP-1. Learning-related increases in MTF-1 and DRP-1 were observed bilaterally in the IMM, but not in either side of the posterior pole of the nidopallium. Cytoplasmic DRP-1 was not changed significantly in any region studied. The results implicate increased, balanced levels of mitochondrial fusion and fission in memory formation up to 24 h after training.Supplementary Video Abstract (Supplemental digital content 1, http://links.lww.com/WNR/A446). PMID- 29189637 TI - Strategies for Prevention and Management of Bleeding Following Pediatric Cardiac Surgery on Cardiopulmonary Bypass: A Scoping Review. AB - OBJECTIVE: We aimed to systematically describe, via a scoping review, the literature reporting strategies for prevention and management of mediastinal bleeding post pediatric cardiopulmonary bypass surgery. DATA SOURCES: MEDLINE, EMBASE, PubMed, and Cochrane CENTRAL Register. STUDY SELECTION: Two authors independently screened publications from 1980 to 2016 reporting the effect of therapeutic interventions on bleeding-related postoperative outcomes, including mediastinal drain loss, transfusion, chest re-exploration rate, and coagulation variables. Inclusions: less than 18 years, cardiac surgery on cardiopulmonary bypass. DATA EXTRACTION: Data from eligible studies were extracted using a standard data collection sheet. DATA SYNTHESIS: Overall, 299 of 7,434 screened articles were included, with observational studies being almost twice as common (n = 187, 63%) than controlled trials (n = 112, 38%). The most frequently evaluated interventions were antifibrinolytic drugs (75 studies, 25%), blood products (59 studies, 20%), point-of-care testing (47 studies, 16%), and cardiopulmonary bypass circuit modifications (46 studies, 15%). The publication rate for controlled trials remained constant over time (4-6/yr); however, trials were small (median participants, 51; interquartile range, 57) and overwhelmingly single center (98%). Controlled trials originated from 22 countries, with the United States, India, and Germany accounting for 50%. The commonest outcomes were mediastinal blood loss and transfusion requirements; however, these were defined inconsistently (blood loss being reported over nine different time periods). The majority of trials were aimed at bleeding prevention (98%) rather than treatment (10%), nine studies assessed both. CONCLUSIONS: Overall, this review demonstrates small trial sizes, low level of evidence, and marked heterogeneity of reported endpoints in the included studies. The need for more, higher quality studies reporting clinically relevant, comparable outcomes is highlighted. Emerging fields such as the use of coagulation factor concentrates, goal-directed guidelines, and anti-inflammatory therapies appear to be of particular interest. This scoping review can potentially guide future trial design and form the basis for therapy-specific systematic reviews. PMID- 29189639 TI - Effects of Closed Endotracheal Suctioning on Systemic and Cerebral Oxygenation and Hemodynamics in Children. AB - OBJECTIVES: To evaluate the effects of closed endotracheal tube suctioning on systemic oxygen saturation, cerebral regional oxygen saturation, and somatic regional (renal) oxygen saturation and hemodynamic variables in children. DESIGN: Prospective observational. SETTING: A tertiary care PICU. SUBJECTS: Children aged 0-18 years, requiring invasive mechanical ventilation and with an arterial line. INTERVENTIONS: Closed endotracheal suction. MEASUREMENTS AND MAIN RESULTS: The study included 19 sedated and intubated children, 0-18 years old. They were enrolled in an ongoing prospective observational study. We used near-infrared spectroscopy for cerebral regional oxygen saturation and somatic regional (renal) oxygen saturation. The timing of each closed endotracheal tube suctioning event was accurately identified from video recordings. We extracted systemic oxygen saturation, cerebral regional oxygen saturation, somatic regional (renal) oxygen saturation, heart rate, and systolic blood pressure and diastolic blood pressure for 5 minutes before and 5 minutes after each event and used these data for analysis. One-minute average values of these variables were used for repeated measures analysis. We analyzed 287 endotracheal tube suctioning episodes in 19 children. Saline was instilled into the endotracheal tube during 61 episodes. The mean heart rate (107.0 +/- 18.7 vs 110.2 +/- 10.4; p < 0.05), mean arterial blood pressure (81.5 +/- 16.1 vs 83.0 +/- 15.6 mm Hg; p < 0.05), and the mean cerebral regional oxygen saturation (64.8 +/- 8.3 vs 65.8 +/- 8.3; p < 0.05) were increased after suctioning. The mean systemic oxygen saturation (96.9 +/- 2.7 vs 96.7 +/- 2.7; p = 0.013) was decreased, whereas the mean somatic regional (renal) oxygen saturation was not significantly different after endotracheal tube suctioning. Repeated-measures analysis revealed transient increases in heart rate, respiratory rate, systolic blood pressure, and diastolic blood pressure; a sustained increase in cerebral regional oxygen saturation; and transient decreases in systemic oxygen saturation and somatic regional (renal) oxygen saturation. Saline instillation did not affect oxygenation or hemodynamic variables. CONCLUSIONS: Closed endotracheal tube suctioning in sedated children is associated with transient but clinically insignificant changes in heart rate, blood pressure, cerebral regional oxygen saturation, systemic oxygen saturation, and somatic regional (renal) oxygen saturation. Saline instillation during endotracheal tube suctioning had no adverse effects on systemic or cerebral oxygenation. PMID- 29189638 TI - Viral DNAemia and Immune Suppression in Pediatric Sepsis. AB - OBJECTIVES: Demonstrate that DNA viremia is common in pediatric sepsis and quantitate its associations with host immune function and secondary infection risk. DESIGN: Retrospective analysis of a prospective cohort study. PATIENTS: Seventy-three children admitted with sepsis-induced organ failure. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: This study was performed as an ancillary investigation to a single-center prospective study of children with severe sepsis. Longitudinally collected, batched, frozen plasma was examined using real time-polymerase chain reaction for the presence of cytomegalovirus, Epstein-Barr virus, herpes simplex virus, human herpes virus-6, torque teno virus, and adenovirus DNA. Innate immune function was also measured longitudinally via quantification of ex vivo lipopolysaccharide -induced tumor necrosis factor-alpha production capacity. Viral DNAemia with a virus other than torque teno virus was detected in 28 of 73 subjects (38%) and included cytomegalovirus 5%, Epstein-Barr virus 11%, herpes simplex virus 4%, human herpes virus-6 8%, and adenovirus 26%. In addition, torque teno virus was detected in 89%. Epstein-Barr virus DNAemia was associated with preexisting immune suppression (p = 0.007) Viral DNAemia was associated with preexisting immune suppression and high risk for the subsequent development of secondary infection (p < 0.05 for both). Subjects with viral DNAemia had lower innate immune function over time compared with those who were virus negative (p < 0.05). CONCLUSIONS: DNAemia from multiple viruses can be detected in septic children and is strongly associated with preexisting immune suppression and secondary infection risk. The role of DNA viruses in the perpetuation of impaired host defense in this setting should be the subject of prospective study. PMID- 29189641 TI - MRI Characteristics of Spinal Ependymoma in WHO Grade II: A Review of 59 Cases. AB - STUDY DESIGN: Retrospective multicenter study. OBJECTIVE: The goal of this study is to determine the characteristic imaging features of spinal ependymoma in a review of magnetic resonance imaging (MRI) data for a large series of surgically proven cases. SUMMARY OF BACKGROUND DATA: Common spinal intramedullary neoplasms are mostly ependymomas and comprise 50% to 60% of spinal neuroepithelial tumors in adults. Preoperative prediction of the pathological diagnosis could enhance surgical planning and explanation of the procedure to patients. However, these types of tumors exhibit a variety of MRI findings. METHODS: Records were examined for 59 patients who underwent surgery for spinal cord ependymoma and had a pathological diagnosis of cellular ependymoma of World Health Organization classification grade II. RESULTS: The ependymomas included 28 in the cervical spine, 34 in the thoracic spine, and 3 conus lesions. All cases were isointense or hypointense on T1-weighted MRI, and 55 (93%) were hyperintense on T2-weighted MRI. Tumors were located centrally in all cases; 50 (85%) showed surrounding cord edema; and 52 (88%) had associated cysts, including 36 (61%) rostral or caudal cysts, 10 (17%) intratumoral cysts, and 6 (10%) with syringomyelia. Of the 59 tumors, 17 (29%) showed the "cap sign," a rim of extreme hypointensity seen around the tumor on T2-weighted images, due to hemosiderin. In gadolinium enhanced MRI, all cases were enhanced, and 27 (46%), 16 (27%), 11 (19%), and 5 (8%) cases showed homogeneous, heterogeneous, rim, and nodular enhancement, respectively. CONCLUSION: Hypointense changes on T2-weighted MRI and hemosiderin deposition reflect easy bleeding. Tumors are associated with various types of cysts, and gadolinium-enhancement patterns reflect a variety of intratumor cellular components. In cases in which the whole tumor shows gadolinium enhancement on MRI, rostral, or caudal cyst and a cap sign with hemorrhage are characteristics of grade II classical ependymoma. LEVEL OF EVIDENCE: 3. PMID- 29189642 TI - VANGL1 Is Not Associated With the Susceptibility of Adolescent Idiopathic Scoliosis in the Chinese Population. AB - STUDY DESIGN: A case-control study. OBJECTIVE: To replicate the association between the VANGL1 gene and the susceptibility of AIS in the Chinese population. SUMMARY OF BACKGROUND DATA: The mutations of VANGL1 gene were recently reported to be associated with AIS in the Danish population. However, there is a lack of replication in other populations. Further analysis of the functional role of VANGL1 in AIS was warranted. METHODS: A total of 1481 female AIS patients and 1372 age-matched healthy controls were included in this study. single nucleotide variant (SNV)s c.407T > A and c.1318T > G were genotyped using allelic-specific multiple ligase detection reactions. single nucleotide polymorphism (SNP)s covering VANGL1 gene were selected using Haploview (v2.6). The associations between theses SNPs and AIS were investigated through Cochran-Armitage trend test by PLINK (v1.90). Relative mRNA expression of VANGL1 in the paraspinal muscles was analyzed for 30 patients and 24 age-matched controls. The difference of mRNA expression level between the two groups was analyzed with the Student t test. RESULTS: There was no case of mutation for all the subjects. A total of 22 SNPs covering VANGL1 were analyzed. All the SNPs were found to have comparable distribution of genotype and allele frequency in the cases and the controls. Moreover, there was no significant difference regarding the mRNA expression of VANGL1 in the two groups. CONCLUSION: VANGL1 gene is not associated with AIS in the Chinese population. Replication studies in other ethnic groups are warranted to further clarify the role of the VANGL1 gene in AIS. LEVEL OF EVIDENCE: 4. PMID- 29189640 TI - Associations of Race and Ethnicity With Patient-Reported Outcomes and Health Care Utilization Among Older Adults Initiating a New Episode of Care for Back Pain. AB - STUDY DESIGN: Secondary analysis of the Back Pain Outcomes using Longitudinal Data (BOLD) cohort study. OBJECTIVE: To characterize associations of self reported race/ethnicity with back pain (BP) patient-reported outcomes (PROs) and health care utilization among older adults with a new episode of care for BP. SUMMARY OF BACKGROUND DATA: No prior longitudinal studies have characterized associations between multiple race/ethnicity groups, and BP-related PROs and health care utilization in the United States. METHODS: This study included 5117 participants >=65 years from three US health care systems. The primary BP-related PROs were BP intensity and back-related functional limitations over 24 months. Health care utilization measures included common diagnostic tests and treatments related to BP (spine imaging, spine-related relative value units [RVUs], and total RVUs) over 24 months. Analyses were adjusted for multiple potential confounders including sociodemographics, clinical characteristics, and study site. RESULTS: Baseline BP ratings were significantly higher for blacks vs. whites (5.8 vs. 5.0; P < 0.001). Participants in all race/ethnicity groups showed statistically significant, but modest improvements in BP over 24 months. Blacks and Hispanics did not have statistically significant improvement in BP-related functional limitations over time, unlike whites, Asians, and non-Hispanics; however, the magnitude of differences in improvement between groups was small. Blacks had less spine-related health care utilization over 24 months than whites (spine-related RVU ratio of means 0.66, 95% confidence interval [CI] 0.51-0.86). Hispanics had less spine-related health care utilization than non-Hispanics (spine-related RVU ratio of means 0.60; 95% CI 0.40-0.90). CONCLUSION: Blacks and Hispanics had slightly less improvement in BP-related functional limitations over time, and less spine-related health care utilization, as compared to whites and non-Hispanics, respectively. Residual confounding may explain some of the association between race/ethnicity and health outcomes. Further studies are needed to understand the factors underlying these differences and which differences reflect disparities. LEVEL OF EVIDENCE: 3. PMID- 29189643 TI - Inter- and Intra-rater Reliability of the Hart-ISSG Proximal Junctional Failure Severity Scale. AB - STUDY DESIGN: Reliability/external validation study. OBJECTIVE: Investigate inter and intrarater reliability of the Hart-International Spine Study Group (ISSG) Proximal Junctional Failure Severity Scale (PJFSS) and its correlation with operative revision in patients with proximal junctional failure (PJF). SUMMARY OF BACKGROUND DATA: The Hart-ISSG PJFSS is a validated classification system for PJF. Reliability of the PJFSS has not been assessed. METHODS: Sixteen detailed clinical scenarios were assessed using the ISSG PJFSS classification in six categories: neurologic status, axial pain, instrumentation issue, proximal kyphotic angle, level of upper instrumented vertebrae (UIV), and severity of UIV/UIV+1 fracture. Eleven spine surgeons evaluated each case in all six categories during two different assessments, and provided recommendations regarding operative revision or observation for each case. Inter- and intrarater reliability were calculated based on intraclass correlation coefficients. RESULTS: All intraclass correlation coefficients demonstrated "almost perfect"' (0.817-0.988) inter-rater agreement for both assessments, except UIV/UIV+1 fracture severity during the second assessment, which demonstrated "substantial" agreement' (0.692). Five of six categories had "almost perfect" mean intrarater reliability (0.805-0.981), while "instrumentation issue" demonstrated "substantial" mean agreement (0.757). Inter-rater reliability for recommendation of surgical intervention was "almost perfect" during both assessments (0.911 and 0.922, respectively). Mean PJFSS scores between the two assessments were significantly higher for cases recommended for operative revision (8.43 +/- 0.90) versus cases recommended for observation (P < 0.0001). CONCLUSION: The ISSG PJFSS is a reliable and repeatable classification system for assessing patients with PJF. Higher PJFSS scales correlate with recommendation for operative revision, extending prior external validation of the PJFSS. LEVEL OF EVIDENCE: 3. PMID- 29189644 TI - Identifying Factors Predictive of Atlantoaxial Fusion Failure in Pediatric Patients: Lessons Learned From a Retrospective Pediatric Craniocervical Society Study. AB - STUDY DESIGN: Multicenter retrospective cohort study with multivariate analysis. OBJECTIVE: To determine factors predictive of posterior atlantoaxial fusion failure in pediatric patients. SUMMARY OF BACKGROUND DATA: Fusion rates for pediatric posterior atlantoaxial arthrodesis have been reported to be high in single-center studies; however, factors predictive of surgical non-union have not been identified by a multicenter study. METHODS: Clinical and surgical details for all patients who underwent posterior atlantoaxial fusion at seven pediatric spine centers from 1995 to 2014 were retrospectively recorded. The primary outcome was surgical failure, defined as either instrumentation failure or fusion failure seen on either plain x-ray or computed tomography scan. Multiple logistic regression analysis was undertaken to identify clinical and technical factors predictive of surgical failure. RESULTS: One hundred thirty-one patients met the inclusion criteria and were included in the analysis. Successful fusion was seen in 117 (89%) of the patients. Of the 14 (11%) patients with failed fusion, the cause was instrumentation failure in 3 patients (2%) and graft failure in 11 (8%). Multivariate analysis identified Down syndrome as the single factor predictive of fusion failure (odds ratio 14.6, 95% confidence interval [3.7 64.0]). CONCLUSION: This retrospective analysis of a multicenter cohort demonstrates that although posterior pediatric atlantoaxial fusion success rates are generally high, Down syndrome is a risk factor that significantly predicts the possibility of surgical failure. LEVEL OF EVIDENCE: 3. PMID- 29189645 TI - A Multicenter Radiographic Evaluation of the Rates of Preoperative and Postoperative Malalignment in Degenerative Spinal Fusions. AB - STUDY DESIGN: Multicenter, retrospective, institutional-review-board -approved study at 18 institutions in the United States with 24 treating investigators. OBJECTIVE: This study was designed to retrospectively assess the prevalence of spinopelvic malalignment in patients who underwent one- or two-level lumbar fusions for degenerative (nondeformity) indications and to assess the incidence of malalignment after fusion surgery as well as the rate of alignment preservation and/or correction in this population. SUMMARY OF BACKGROUND DATA: Spinopelvic malalignment after lumbar fusion has been associated with lower postoperative health-related quality of life and elevated risk of adjacent segment failure. The prevalence of spinopelvic malalignment in short-segment degenerative lumbar fusion procedures from a large sample of patients is heretofore unreported and may lead to an under-appreciation of these factors in surgical planning and ultimate preservation or correction of alignment. METHODS: Lateral preoperative and postoperative lumbar radiographs were retrospectively acquired from 578 one- or two-level lumbar fusion patients and newly measured for lumbar lordosis (LL), pelvic incidence (PI), and pelvic tilt. Patients were categorized at preop and postop time points as aligned if PI-LL < 10 degrees or malaligned if PI-LL>=10 degrees . Patients were grouped into categories based on their alignment progression from pre- to postoperative, with preserved (aligned to aligned), restored (malaligned to aligned), not corrected (malaligned to malaligned), and worsened (aligned to malaligned) designations. RESULTS: Preoperatively, 173 (30%) patients exhibited malalignment. Postoperatively, 161 (28%) of patients were malaligned. Alignment was preserved in 63%, restored in 9%, not corrected in 21%, and worsened in 7% of patients. CONCLUSION: This is the first multicenter study to evaluate the preoperative prevalence and postoperative incidence of spinopelvic malalignment in a large series of short-segment degenerative lumbar fusions, finding over 25% of patients out of alignment at both time points, suggesting that alignment preservation/restoration considerations should be incorporated into the decision-making of even degenerative lumbar spinal fusions. LEVEL OF EVIDENCE: 3. PMID- 29189647 TI - The Use of Simulation in Physician Assistant Programs: A National Survey. AB - PURPOSE: The purpose of this study was to develop a national-level description of the current use of simulation activities in physician assistant (PA) education and to assess the degree to which the use of simulation varies by PA program size and institutional type. METHODS: An electronic survey on medical simulation was sent to 177 PA program directors or to a designated simulation activities coordinator, using the directory on the Physician Assistant Education Association website. The survey addressed program characteristics, types of simulation modalities in use, and frequency of use of those modalities in PA training. The specific content areas addressed were error disclosure, medical knowledge, patient care, and psychomotor skills. RESULTS: The survey was emailed 3 times from early April to mid-May 2014, with a follow-up call to nonrespondents in August 2014. Of the 177 PA programs contacted, 63 completed the survey, for a response rate of 35.6%. Results indicate widespread use of simulation by survey respondents, especially in teaching, assessment of medical knowledge, and clinical skills, with somewhat lower levels of use in content areas such as error disclosure, delivery of bad news, and team training. CONCLUSIONS: Although barriers exist to its use in training health care professionals, simulation has become an important tool for training PAs in a variety of medical and interpersonal skills. It is also clear that simulation is an important tool for conducting interprofessional training. More research is needed to identify optimal approaches to the use of simulation in health care professions training. PMID- 29189646 TI - The Impact of Early Involvement in a Postdischarge Support Program for Ostomy Surgery Patients on Preventable Healthcare Utilization. AB - PURPOSE: To evaluate the impact of a postdischarge ostomy support program as an adjunct to nurse-led ostomy care on preventable healthcare utilization. DESIGN: A cross-sectional study. SUBJECTS AND SETTING: A postdischarge support program offered by an ostomy product's manufacturer provides persons living with an ostomy with patient-centered and easily accessible assistance. Individuals who underwent ostomy surgery within 18 months prior to the survey date were selected from an ostomy patient database maintained by the ostomy patient support program provider. Of 7026 surveys sent to program enrollees, 493 (7%) responded, compared with 225 (5%) out of 4149 surveys sent to individuals in a comparison group. The 2 groups were similar in demographics. A majority of the survey respondents were female (60% of program enrollees vs 55% of respondents in the comparison group). Among the program enrollees, 44% had colostomy, 43% had ileostomy, 10% had urostomy, and 4% had at least 2 types of ostomy surgery compared with 52%, 32%, 12%, and 4% of the respondents in a comparison group, respectively. METHODS: The study compared hospital readmission and emergency room (ER) visit rates attributable to ostomy complications between program enrollees and respondents in the comparison group. The event rates were measured in 2 study periods: within the first month of discharge and after the first month of discharge. Eligible individuals received an online survey that included the following domains: characteristics of ostomy surgery; readmissions and ER visits within the first month or after the first month of discharge, including reasons for preventable events; and level of health care access. Multivariate logistic regressions controlling for covariates were applied to investigate associations between program enrollment and ostomy-related readmission or ER visit rates. RESULTS: Logistic regression analyses showed that, when compared with respondents in the comparison group, program enrollees had a significantly lower likelihood of being readmitted and visiting the ER due to ostomy complications after the first month of hospital discharge and up to 18 months postdischarge (odds ratio [OR] = 0.45; 95% confidence interval [CI], 0.27-0.73; and OR = 0.37; 95% CI, 0.22-0.64, respectively). CONCLUSIONS: Findings suggest that enrolling patients in the postdischarge ostomy support program provides an effective approach to reducing preventable healthcare utilization. PMID- 29189648 TI - Quantifying Cadaver Use in Physician Assistant Anatomy Education. AB - PURPOSE: To quantify the number of cadavers used in physician assistant (PA) anatomy education and to ascertain the origins of those cadavers. METHODS: An electronic survey was generated and distributed to all schools that had been accredited by the Accreditation Review Commission on Education for the Physician Assistant. Responses were reported using descriptive statistics. RESULTS: The survey had a 49% response rate. Among the responding programs, 79% reported working with 655 cadavers, with an average of one cadaver per 5.72 students. Programs reported that 21% receive cadavers from multiple sources. Of all programs using cadavers, 62% receive cadavers from medical schools, 23% from in house anatomical gift programs, 19% from state anatomy boards, 9% from private organizations, and 8% from other sources. Anatomy educators reported that 55% know the origins of the cadavers in their programs, 18% do not, and 27% are uncertain. In categorizing cadavers at their programs, 56% were reported as registered donors, 4% as next-of-kin donations, 1% as unclaimed dead, 17% as uncertain origin, and 22% as unaccounted for by respondents. CONCLUSIONS: Among educators who teach anatomy to PA students, 45% do not know or are uncertain of the origins of the cadavers in their programs. Of the reported 655 cadavers used in PA education, 289 were not categorized as registered donors. Facing the expansion of PA programs, educators need to be aware of cadavers' origins to ensure that all aspects of PA education are consistent with the ethics that the students are being taught. Those ethics include the need for informed consent for all cadavers involved in PA education. PMID- 29189649 TI - Physician Assistant Student Training for the Inpatient Setting: A Needs Assessment. AB - PURPOSE: The number of physician assistants (PAs) practicing hospital medicine is rapidly expanding. Little research has been done to determine which inpatient medicine rotation experiences are most helpful to prepare PA students for a career in inpatient medicine. We aimed to determine those skills that practicing hospitalists believe are most critical for PA students to master and to describe hospitalists' current understanding of PA training. We also sought to evaluate the current performance of our own inpatient medicine rotation for PA students. METHODS: We surveyed 85 practicing hospitalists, including physicians and advanced-practice providers, from 3 hospitals in the Duke University Health System to identify (1) the clinical topics and skills deemed most essential for PA students on an inpatient medicine rotation, (2) the percentage of hospitalists able to correctly answer basic questions about PA training, and (3) current rotation performance. Descriptive statistics were used to summarize responses. RESULTS: Hospitalists identified the clinical conditions and health care systems with the most educational value for PA students. Hospitalists were found to have variable levels of understanding of the PA training pathway, with more than 20% incorrectly answering questions about the training process. According to mean responses, the rotation performed positively for 15 of 19 medical conditions. The majority of survey respondents suggested that a formal curriculum would help faculty teach and improve the learning experience for PA students. CONCLUSIONS: Identifying the most essential content can facilitate curriculum development. Hospitalists have a knowledge gap about the training of PA students. The inpatient medicine rotation was rated positively, but survey responses suggested that a formal curriculum could have a positive effect and would be well received. PMID- 29189650 TI - Application of Adult Learning Theory to Physician Assistant Education. AB - Just as we depend on medical science and research to treat patients, we should connect our teaching methods to educational theory and research. In particular, the foundations of adult education philosophy and adult learning theories can be deliberately applied to further strengthen the clinical learning experience of physician assistants (PAs). We propose that PA educators should be aware of how their personal philosophy of education affects their teaching practice. In addition, educators should apply learning theories to both classroom process and content. We provide an overview of 5 categories of learning philosophy (liberal, progressive, behavioral, humanist, and radical) and 6 learning theories (experiential learning, reflective practice, situated learning, communities of practice, transformative learning, and critical consciousness) of adult education. Concrete examples of how to apply adult education theory to meet specific learning objectives for PA students are described. Understanding how to apply learning theory and identify and shape one's educational philosophy provides theoretical and empirical support for what we often deem an intuitive process. PMID- 29189651 TI - Are You SURE You Want to Send That? A Model for Email Professionalism in Medical Education. AB - Email is an essential method of communication within academic medical environments and elsewhere. There is a growing body of literature that focuses on provider-to-patient communication in addition to studies examining the intersection of social networking and professionalism. Relatively little research exists, however, regarding the components of professional email interactions or "best practices" for electronic correspondence among colleagues, faculty, and trainees. After reviewing the existing literature, the authors created a practical approach for skillful email construction; the SURE model proposes a simplified framework that teaching institutions can use to improve interdisciplinary interactions and enhance email professionalism. PMID- 29189652 TI - Physician Assistant Student Perceptions of an Interprofessional, Peer-to-Peer Oral Health Curriculum Led by Dental Students. AB - PURPOSE: Physician assistants (PA) are health care team members who often work in primary care. Providing oral health education to PAs during training could improve oral health for vulnerable patients who seek treatment in the primary care setting and who are less able to access dental care. The purpose of this study was to assess the effectiveness of a peer-to-peer oral health curriculum taught by dental students to their PA student colleagues. METHODS: Dental students presented an interactive, case-based curriculum, followed by a hands-on oral examination training session. PA student feedback was obtained, and results were analyzed. RESULTS: Students found the content to be highly relevant and well presented. Conveying oral health competencies to future primary care providers may reduce oral health disparities. CONCLUSIONS: PA students reported improved understanding of oral health and indicated they would incorporate what they had learned into their future clinical practice. PMID- 29189654 TI - The Sacred Seven Elective: Integrating the Health Humanities Into Physician Assistant Education. PMID- 29189653 TI - Preceptors' Perceptions of Interprofessional Practice, Student Interactions, and Strategies for Interprofessional Education in Clinical Settings. AB - PURPOSE: This study describes clinical preceptors' perceptions of interprofessional practice, the nature and variety of physician assistant (PA) students' interprofessional interactions during clinical training, and factors that facilitate or hinder interprofessional education (IPE) in clinical settings. METHODS: This qualitative study involved interviews with preceptors that were audio-recorded, transcribed, and then analyzed through an iterative process to identify key conceptual themes. RESULTS: Fourteen preceptors from a variety of clinical settings participated. Four themes were identified: (1) preceptors define interprofessional practice differently; (2) students learn about teams by being a part of teams; (3) preceptors separate students to avoid diluting learning experiences; and (4) preceptors can facilitate IPE by introducing students to members of the team and role modeling team skills. CONCLUSIONS: The themes may inform PA educators' efforts to increase IPE in clinical settings through educational interventions with both preceptors and students.

AB - Perinatal tuberculosis is an uncommon condition but with a high mortality and a challenging diagnosis. We present 4 cases of perinatal tuberculosis managed between 1991 and 2014 in a Spanish Tertiary Hospital. The infection should be considered in patients with progressive respiratory symptoms and with a poor response to conventional antibiotic therapy, especially in those with positive epidemiologic risk. Bronchoscopy can be a useful tool for diagnosis. PMID- 29189659 TI - High Prevalence of Lipid Abnormalities and Insulin Resistance Among Antiretroviral Naive HIV-infected Children in India. AB - BACKGROUND: As large numbers of children are accessing antiretroviral therapy (ART) in India, we evaluated the dietary intake, growth pattern and risk of metabolic complications like dyslipidemia and insulin resistance among ART-naive HIV-infected children (CLHIV). METHODS: CLHIV 2-12 years of age, at the time of initiating ART in Chennai and Bangalore, were assessed for their dietary intake, anthropometry, blood CD4 cell count, HIV-1 viral load, fasting serum lipids, glucose and insulin. Homeostatic model assessment-insulin resistance was derived. RESULTS: Three hundred and ninety CLHIV (mean age [SD]: 8 [3] yrs; median viral load: 141,000 [25,876-436,000] copies/mL) were started on non-nucleoside reverse transcriptase inhibitor-based ART. Perinatal infection was documented among 97%. Sixty percent of children were in stage 3 or 4 of World Health Organization clinical staging of HIV/AIDS. Food insecurity was seen in 40% of households. A total of 204 children (52.4%) were stunted and 224 (57.6%) were underweight. Stunting seemed to be more prevalent with increasing age (0-4 years: 48%; >9 years: 60%). Mean intakes of calories, iron, folate and calcium were significantly less than recommended dietary allowances across all age groups. Dyslipidemia, in terms of any abnormal triglycerides or total cholesterol or low density lipoprotein cholesterol (excluding high-density lipoprotein cholesterol), was seen in approximately 40% of children; insulin resistance in 17%; and C reactive protein in risk range of metabolic syndrome in 24% of children. CONCLUSIONS: In the background of high food insecurity and malnutrition, cardiometabolic abnormalities were seen in 20%-35% of ART-naive CLHIV in India emphasizing close monitoring of these children for long-term cardiovascular morbidities after initiation of ART. PMID- 29189658 TI - Discharge Criteria for Bronchiolitis: An Unmet Need. AB - BACKGROUND: Admission criteria and standardized management strategies for bronchiolitis are addressed in several guidelines and have shown to be beneficial; however, guidance regarding discharge criteria is limited and widely variable. We assessed the impact on clinical outcomes of a discharge protocol for children <2 years of age hospitalized with bronchiolitis in a tertiary care pediatric hospital. METHODS: In October 2013, a protocol to standardize the discharge of children with bronchiolitis was implemented in the infectious diseases (ID) ward but not in other pediatric units caring for these children (non-ID). The protocol included objective clinical criteria and a standardized oxygen weaning pathway. Patients were identified via International Classification of Diseases-9 codes and data manually reviewed. We compared length of stay (LOS) and readmission rates within 2 weeks of discharge according to protocol implementation (ID versus non-ID), adjusted for demographic factors, comorbidities, viral etiology and stratified by pediatric intensive care unit admission. RESULTS: From October 2013 to May 2015, 1118 children were hospitalized in ID and 695 in non-ID units. Median age was 4.5 months, 55% were males and 28% had comorbidities. LOS was 36% longer in non-ID units (risk ratio: 1.36 [1.27-1.45]; P < 0.001) adjusted for age, gender, comorbidities and viral etiology. Difference in LOS remained significant after excluding children with comorbidities and stratifying by pediatric intensive care unit admission. Readmission rates were comparable between units (ID, 2.9% versus non-ID, 2.6%). CONCLUSIONS: A standardized discharge protocol for bronchiolitis reduced LOS without increasing readmission rates. Unifying bronchiolitis discharge criteria and oxygen weaning pathways could positively impact hospital-based patient care for this condition.

AB - This study introduces a novel technique for liver retraction during laparoscopic gastrectomy and assesses its impact on postoperative recovery. This study included 139 patients in whom Nelaton catheters (n=57) or Nathanson retractors (n=82) were used for liver retraction. Serum liver enzyme levels were measured preoperatively and on the first, second, third, fifth, and seventh postoperative days. Clinicopathologic features and postoperative recovery variables between the 2 groups were compared. The aspartate aminotransferase, alanine aminotransferase, and C-reactive protein levels were significantly lower (P<0.001, P<0.001, and P=0.007, respectively), and the day of first flatus, the day of initiating a soft diet, and the length of hospital stay were shorter in the Nelaton catheter U shaped retractor group than those seen in the Nathanson retractor group (P=0.035, P=0.002, and P=0.024, respectively). Atraumatic liver retraction with Nelaton catheters is recommended in laparoscopic gastrectomy.

AB - PURPOSE: Undertake a comparison between laparoscopic distal pancreatectomy (LDP) and open distal pancreatectomy (ODP) for the management of benign and malignant lesions. METHODS: A case series study of 93 consecutive patients subjected to a distal pancreatectomy for pancreatic tumors between 2001 and 2015. In each patient, clinical and surgical characteristic, postoperative course, histopathologic examination, and survival were analyzed. RESULTS: LDP was associated with significantly less operative blood loss (50 mL vs. 300 mL; P<0.01), higher spleen preservation rate (52.6% vs. 19.2%; P<0.01) and shorter hospital stay (5 d vs. 8 d; P<0.01). In patients with adenocarcinoma, survival at 1 and 5 years were 63.5% and 15.9% in the ODP group versus 66.7% and 33.3% in the LDP group (P=0.43). CONCLUSIONS: LDP is a safe and feasible procedure for DP resections. LDP offers advantages over ODP in terms of reduction of operative blood loss, higher spleen preservation rate, and shorter hospital stay. PMID- 29189662 TI - Does Peritoneal Suction Drainage Reduce Pain After Gynecologic Laparoscopy? AB - This study evaluated the effect of drain placement on pain intensity after gynecologic laparoscopy. This study enrolled 120 patients with benign gynecologic lesions who underwent laparoscopic surgery. Patients were randomly divided into a standard group or the modified group. The modified group received suction drains that remained in place until 12 hours after surgery. We assessed patients' mean pain scores according to a visual analog scale at 12 and 24 hours after surgery. The mean pain score in the modified group was 6.01+/-1.96 at 12 hours after surgery and 3.86+/-1.57 at 24 hours after surgery. The standard group had a mean pain score of 5.43+/-1.7 at 12 hours after surgery and 3.51+/-1.27 at 24 hours after surgery. These findings did not significantly differ (P=0.6) even though the mean dose of parenteral analgesia was 0.68+/-0.83 in the standard group and 0.41+/-0.67 in the modified group (P=0.05). We observed no differences in complications and hospital stay between the groups. The data suggest that drainage may not reduce postoperative pain and should be used in its traditional role for potential bleeding or infections. PMID- 29189663 TI - Decrease of Sphincter Preserving Length Lowers the Postoperative Genital Function for Patients With Rectal Cancer. AB - BACKGROUND AND OBJECTIVE: With the increase in sphincter preserving rate of rectal cancer (RC) cancer, postoperative quality-of-life, such as genital dysfunction, has become a major issue in the patient management. In this study, we proposed a measurement, namely, the sphincter preserving length (SPL), and investigated the relationship between SPL and postoperative genital function and survival in RC patients. METHODS: A total of 536 male patients who had a diagnosis of RC and underwent sphincter preserving rectal resection in the Sixth Affiliated Hospital of Sun Yat-sen University and the First Affiliated Hospital of Sun Yat-sen University between October 1997 and December 2013 were included in our study. SPL was defined as the distance between the lowest edge of the tumor to dentate line. Postoperative genital function was evaluated by erection function and ejaculation function. Five-year survival status was extracted from the hospital database. RESULTS: Larger SPL was significantly associated with poorer postoperative erection and ejaculation function. For a SPL of 7.25 cm, the sensitivity and specificity of the diagnosis of erection dysfunction was 68.6% and 68.8%, respectively. The corresponding sensitivity and specificity for the diagnosis of ejaculation dysfunction was 70.9% and 75.7%, respectively. SPL was also negatively associated with survival rate. Compared with lower anterior resection, patients with lower RC who underwent local resection or draw-out colon anal anastomosis had better postoperative genital function. CONCLUSIONS: SPL might be a useful measurement to assess the risk of postoperative genital dysfunction and survival status and an indicator for initiation of early preventative treatment in patients with RC. PMID- 29189665 TI - Therapeutic Drug Monitoring of Busulfan for the Management of Pediatric Patients: Cross-Validation of Methods and Long-Term Performance. AB - BACKGROUND: Busulfan (Bu) is an alkylating agent used as part of the conditioning regimen in pediatric patients before hematopoietic stem cell transplantation. Despite intravenous (IV) administration and dosing recommendations based on age and weight, reports have revealed interindividual variability in Bu pharmacokinetics and the outcomes of hematopoietic stem cell transplantation. In this context, adjusting doses to Bu's narrow therapeutic window is advised. We aimed to assess the utility of therapeutic drug monitoring (TDM) of Bu in children, the reliability of Bu quantification methods, and its stability in plasma when stored for up to 5 years. METHODS: Eighteen patients from our TDM center (252 samples) were included. All of them received a 2-hour Bu IV infusion 4 times daily for a total of 16 doses. The first dose of Bu was age/weight-based, and the subsequent doses were adjusted from third or fifth dose onward based on the estimated first dose pharmacokinetic parameters to target steady-state concentrations (Css) of 600-900 ng/mL. The performance of our unit's high performance liquid chromatography with tandem mass spectrometry method was assessed using a quality control (QC, 35 series) chart. International, multicenter, cross-validation test (n = 21) was conducted to validate different analytical methods. To assess Bu stability, regression analyses and Bland-Altman plots were performed on measurements at repeated time points on samples stored at -80 degrees C for up to 5 years. RESULTS: We observed a 4.2-fold interindividual variability in Bu Css after the first dose, with only 28% of children having a Css within the target range. During the 4 days of conditioning, 83% of children had their doses modified according to TDM recommendations. This achieved a Css within the target range in 75% of the children. Routine QC measurements were generally within the +/-15% range around theoretical values, showing the optimal robustness of our center's analytical method. Two of the 21 Bu TDM centers returned inadequate results during cross-validation testing; both used a UV detection method. Storage at -80 degrees C led to a fall in Bu content of 14.9% +/- 13.4% at 2-4 years and of 20% +/- 5% by 5 years (roverall = 0.92). CONCLUSIONS: We conclude that TDM is an effective method of achieving targeted Bu levels in children. QC programs are crucial to monitoring and maintaining the quality of an analytical method. PMID- 29189664 TI - Early Therapeutic Drug Monitoring of Posaconazole Oral Suspension in Patients With Hematologic Malignancies. AB - BACKGROUND: Therapeutic drug monitoring (TDM) of posaconazole is usually performed 1 week after starting the drug because of its long half-life. However, previous studies showed that measuring the posaconazole plasma concentration (PPC) on day 3 is effective for predicting steady-state levels. The purpose of this study was to evaluate the relevance of early TDM (day 3) of posaconazole for achieving an optimal PPC. METHODS: This prospective study was conducted from September 2014 to August 2016. A total of 148 patients with acute myeloid leukemia or myelodysplastic syndromes received a 200 mg posaconazole oral suspension 3 times daily for fungal prophylaxis. During the period from September 2014 to December 2015 (control group), no dose adjustment was performed on day 3. During the period from January 2016 to Aug 2016 (early TDM group), the frequency of posaconazole 200-mg administration was increased to 4 times daily in patients whose PPC on day 3 was <400 ng/mL. The cutoff value for optimal PPC on day 8 was defined as 500 ng/mL. RESULTS: In 21 of 107 patients (20%) in the control group, PPC was <400 ng/mL on day 3. In 15 (71%) of these 21 patients, the PPC was suboptimal on day 8. In the early TDM group, the PPC was <400 ng/mL on day 3 in 4 of 41 patients (10%). After increasing the posaconazole administration frequency in these 4 patients, PPC was suboptimal on day 8 in 1 patient (25%). In both groups, 104 patients had a PPC of >=500 ng/mL on day 3, but 7% (7/104) of these had a suboptimal level on day 8. CONCLUSIONS: Early TDM on day 3 for posaconazole suspension may help more patients achieve optimal drug levels on day 8, although TDM on day 8 is needed even in patients with optimal levels on day 3. PMID- 29189666 TI - Validity of Wearable Activity Monitors during Cycling and Resistance Exercise. AB - INTRODUCTION: The use of wearable activity monitors has seen rapid growth; however, the mode and intensity of exercise could affect the validity of heart rate (HR) and caloric (energy) expenditure (EE) readings. There is a lack of data regarding the validity of wearable activity monitors during graded cycling regimen and a standard resistance exercise. The present study determined the validity of eight monitors for HR compared with an ECG and seven monitors for EE compared with a metabolic analyzer during graded cycling and resistance exercise. METHODS: Fifty subjects (28 women, 22 men) completed separate trials of graded cycling and three sets of four resistance exercises at a 10-repetition-maximum load. Monitors included the following: Apple Watch Series 2, Fitbit Blaze, Fitbit Charge 2, Polar H7, Polar A360, Garmin Vivosmart HR, TomTom Touch, and Bose SoundSport Pulse (BSP) headphones. HR was recorded after each cycling intensity and after each resistance exercise set. EE was recorded after both protocols. Validity was established as having a mean absolute percent error (MAPE) value of <=10%. RESULTS: The Polar H7 and BSP were valid during both exercise modes (cycling: MAPE = 6.87%, R = 0.79; resistance exercise: MAPE = 6.31%, R = 0.83). During cycling, the Apple Watch Series 2 revealed the greatest HR validity (MAPE = 4.14%, R = 0.80). The BSP revealed the greatest HR accuracy during resistance exercise (MAPE = 6.24%, R = 0.86). Across all devices, as exercise intensity increased, there was greater underestimation of HR. No device was valid for EE during cycling or resistance exercise. CONCLUSIONS: HR from wearable devices differed at different exercise intensities; EE estimates from wearable devices were inaccurate. Wearable devices are not medical devices, and users should be cautious when using these devices for monitoring physiological responses to exercise. PMID- 29189667 TI - Repeatability and Meaningful Change of CPET Parameters in Healthy Subjects. AB - INTRODUCTION/PURPOSE: Cardiopulmonary exercise testing (CPET) plays an important role in clinical medicine and research. Repeatability of CPET parameters has not been well characterized, but is important to assess variability and determine if there have been meaningful changes in a given CPET parameter. METHODS: We recruited 45 healthy subjects and performed two symptom-limited CPET within 30 d using a cycle ergometer. Differences in relevant CPET parameters between CPET-1 and CPET-2 were assessed using a paired t-test. Coefficient of variation (CoV) and Bland-Altman plots are reported. Factors that may be associated with variability were analyzed (sex, age, time of day, fitness level). The coefficient of repeatability was calculated for peak oxygen consumption (VO2) and VO2 at lactate threshold (LT) to establish a 95% threshold for meaningful change. RESULTS: There were no significant differences between tests in the parameters reported. Specifically, we found overall low CoV in peak VO2 (4.9%), VO2@LT (10.4%), peak O2 pulse (4.6%), peak minute ventilation (VE; 7.4%), VE/VCO2@LT (4.0%), and VE/VO2@LT (4.8%). The CoV for peak respiratory exchange ratio@LT was significantly affected by diurnal factors; age, sex, and fitness level did not affect variability. The 95% threshold for meaningful change was 0.540 L.min in peak VO2 and 0.520 L.min in VO2@LT. CONCLUSIONS: Repeatability of CPET parameters is generally higher than previously reported. There were no significant differences in variability related to sex, age, and fitness level; diurnal factors had a limited effect. The threshold for meaningful change in peak VO2 and for VO2@LT should be considered when gauging a response to therapies or training. PMID- 29189668 TI - The Role of Airway Inflammation and Bronchial Hyperresponsiveness in Athlete's Asthma. AB - PURPOSE: Asthma is frequently reported in endurance athletes. The aim of the present study was to assess the long-term airway inflammatory response to endurance exercise in high-level athletes with and without asthma. METHODS: In a cross-sectional design, 20 asthmatic athletes (10 swimmers and 10 cross-country skiers), 19 athletes without asthma (10 swimmers and 9 cross-country skiers), and 24 healthy nonathletes completed methacholine bronchial challenge, lung function tests, and sputum induction on two separate days. All athletes competed on a national or international level and exercised >=10 h.wk. The nonathletes exercised <=5 h.wk and reported no previous lung disease. Bronchial hyperresponsiveness (BHR) was defined as a methacholine provocation dose causing 20% decrease in the forced expiratory volume in 1 s of <=8 MUmol. RESULTS: BHR was present in 13 asthmatic athletes (62%), 11 healthy athletes (58%), and 8 healthy nonathletes (32%), and the prevalence differed among groups (P = 0.005). Sputum inflammatory and epithelial cell counts did not differ between groups and were within the normal range. Median (25th to 75th percentiles) sputum interleukin-8 was elevated in both asthmatic (378.4 [167.0-1123.4]) and healthy (340.2 [175.5-892.4]) athletes as compared with healthy nonathletes (216.6 [129.5 314.0], P = 0.02). No correlations were found between provocation dose causing 20% decrease and sputum cell counts. CONCLUSION: Independent of asthma diagnosis, a high occurrence of BHR and an increased sputum interleukin-8 were found in athletes as compared with nonathletes. Airway inflammation or epithelial damage was not related to BHR. PMID- 29189669 TI - Measurement of Dead Space Fraction Upon ICU Admission Predicts Length of Stay and Clinical Outcomes Following Bidirectional Cavopulmonary Anastomosis. AB - OBJECTIVES: Increased alveolar dead space fraction has been associated with prolonged mechanical ventilation and increased mortality in pediatric patients with respiratory failure. The association of alveolar dead space fraction with clinical outcomes in patients undergoing bidirectional cavopulmonary anastomosis for single ventricle congenital heart disease has not been reported. We describe an association of alveolar dead space fraction with postoperative outcomes in patients undergoing bidirectional cavopulmonary anastomosis. DESIGN: In a retrospective case-control study, we examined for associations between alveolar dead space fraction ([PaCO2 - end-tidal CO2]/PaCO2), arterial oxyhemoglobin saturation, and transpulmonary gradient upon postoperative ICU admission with a composite primary outcome (requirement for surgical or catheter-based intervention, death, or transplant prior to hospital discharge, defining cases) and several secondary endpoints in infants following bidirectional cavopulmonary anastomosis. SETTINGS: Cardiac ICU in a tertiary care pediatric hospital. PATIENTS: Patients undergoing bidirectional cavopulmonary anastomosis at our institution between 2011 and 2016. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 191 patients undergoing bidirectional cavopulmonary anastomosis, 28 patients were cases and 163 were controls. Alveolar dead space fraction was significantly higher in the case (0.26 +/- 0.09) versus control group (0.17 +/- 0.09; p < 0.001); alveolar dead space fraction at admission was less than 0.12 in 0% of cases and was greater than 0.28 in 35% of cases. Admission arterial oxyhemoglobin saturation was significantly lower in the case (77% +/- 12%) versus control group (83% +/- 9%; p < 0.05). Sensitivity and specificity for future case versus control assignment was best when prebidirectional cavopulmonary anastomosis risk factors, admission alveolar dead space fraction (AUC, 0.74), and arterial oxyhemoglobin saturation (AUC, 0.65) were combined in a summarial model (AUC, 0.83). For a given arterial oxyhemoglobin saturation, the odds of becoming a case increased on average by 181% for every 0.1 unit increase in alveolar dead space fraction. Admission alveolar dead space fraction and arterial oxyhemoglobin saturation were linearly associated with prolonged ICU length of stay, hospital length of stay, duration of mechanical ventilation, and duration of thoracic drainage (p < 0.001 for all). CONCLUSIONS: Following bidirectional cavopulmonary anastomosis, alveolar dead space fraction in excess of 0.28 or arterial oxyhemoglobin saturation less than 78% upon ICU admission indicates an increased likelihood of requiring intervention prior to hospital discharge. Increasing alveolar dead space fraction and decreasing arterial oxyhemoglobin saturation are associated with increased lengths of stay. PMID- 29189670 TI - Psychological and Psychiatric Outcomes Following PICU Admission: A Systematic Review of Cohort Studies. AB - OBJECTIVE: Admissions to PICU places pediatric patients at increased risk of persistent psychological and psychiatric morbidity. This systematic review aimed to summarize and critically examine literature regarding psychological and psychiatric outcomes of pediatric patients following PICU admission. DATA SOURCES: MEDLINE, Web of Science, Cochrane Library, Science Direct, PsycInfo, CINAHL, LILACS, and SciELO were searched up to May 2016. STUDY SELECTION: Cohort studies about psychological and psychiatric outcomes of pediatric patients following PICU admission; full-text records published in English, Spanish, or Portuguese in peer-reviewed journals from 2000 to 2015 were included. Neonatal patient population (age, <1 mo), follow-up after PICU discharge (<3 mo), and nonprimary literature were excluded. Two reviewers independently screened studies based on the predetermined exclusion criteria. DATA EXTRACTION: Data were extracted using an adapted tool. The internal validity and risk of bias were assessed using Newcastle-Ottawa Scale. DATA SYNTHESIS: The search yielded 1,825 studies after the removal of duplications, of which eight met the inclusion criteria. Methodologic quality of the studies ranged from low to high, with an average score of five of nine. Of all the studies, half had a control group. Regarding the length of follow-up, most of the studies ranged from 3 to 12 months. CONCLUSIONS: Psychological and psychiatric outcomes after pediatric critical illness appear to be substantial issues that need to be further studied. Our review highlights the need for psychological screening of pediatric patients and their parents following PICU admission since these patients are a vulnerable population at risk for developing psychiatric responses. PMID- 29189671 TI - Neural Breathing Pattern and Patient-Ventilator Interaction During Neurally Adjusted Ventilatory Assist and Conventional Ventilation in Newborns. AB - OBJECTIVE: To compare neurally adjusted ventilatory assist and conventional ventilation on patient-ventilator interaction and neural breathing patterns, with a focus on central apnea in preterm infants. DESIGN: Prospective, observational cross-over study of intubated and ventilated newborns. Data were collected while infants were successively ventilated with three different ventilator conditions (30 min each period): 1) synchronized intermittent mandatory ventilation (SIMV) combined with pressure support at the clinically prescribed, SIMV with baseline settings (SIMVBL), 2) neurally adjusted ventilatory assist, 3) same as SIMVBL, but with an adjustment of the inspiratory time of the mandatory breaths (SIMV with adjusted settings [SIMVADJ]) using feedback from the electrical activity of the diaphragm). SETTING: Regional perinatal center neonatal ICU. PATIENTS: Neonates admitted in the neonatal ICU requiring invasive mechanical ventilation. MEASUREMENTS AND MAIN RESULTS: Twenty-three infants were studied, with median (range) gestational age at birth 27 weeks (24-41 wk), birth weight 780 g (490 3,610 g), and 7 days old (1-87 d old). Patient ventilator asynchrony, as quantified by the NeuroSync index, was lower during neurally adjusted ventilatory assist (18.3% +/- 6.3%) compared with SIMVBL (46.5% +/-11.7%; p < 0.05) and SIMVADJ (45.8% +/- 9.4%; p < 0.05). There were no significant differences in neural breathing parameters, or vital signs, except for the end-expiratory electrical activity of the diaphragm, which was lower during neurally adjusted ventilatory assist. Central apnea, defined as a flat electrical activity of the diaphragm more than 5 seconds, was significantly reduced during neurally adjusted ventilatory assist compared with both SIMV periods. These results were comparable for term and preterm infants. CONCLUSIONS: Patient-ventilator interaction appears to be improved with neurally adjusted ventilatory assist. Analysis of the neural breathing pattern revealed a reduction in central apnea during neurally adjusted ventilatory assist use. PMID- 29189672 TI - Invasive Haemophilus influenzae Serotype a Infection in Children: Clinical Description of an Emerging Pathogen-Alaska, 2002-2014. AB - BACKGROUND: Invasive infections from Haemophilus influenzae serotype a (Hia) have been reported with increasing frequency, especially among indigenous populations. However, there are limited population-based studies of clinical severity. We studied invasive Hia infections in Alaska to determine clinical characteristics, mortality and sequelae. METHODS: We defined an invasive Hia infection as the first detection of Hia from a usually sterile site in a child <10 years of age from Alaska. We identified cases using the Alaska Invasive Bacterial Diseases Surveillance System and reviewed medical charts up to 2 years after reported illness. RESULTS: We identified invasive Hia infections in 36 children, 28 (78%) <1 year old, 34 (94%) living in an Alaskan village and 25 (69%) without documented underlying illness. Overlapping clinical presentations included meningitis in 15 children (42%); bacteremia and pneumonia in 10 children (28%); and bone, joint or soft tissue infections in 10 children (22%). In 4 other children, no source of invasive infection was identified. Intensive care was provided for 11 children (31%); 12 children (33%) required surgical intervention. One year after infection, 4 children (11%) had died from Hia, and 5 children (14%) had ongoing neurologic sequelae. CONCLUSIONS: Invasive Hia infections in Alaska occurred predominantly in Alaska Native infants in rural communities. Although one-third of children had preexisting conditions, most cases occurred without known comorbidity. Clinical syndromes were frequently severe. One year after infection, 1 in 4 children had either died or had neurologic sequelae. An effective vaccine would prevent significant morbidity and mortality in affected populations. PMID- 29189673 TI - Rotavirus Genotypes Circulating in Brazil Before and After the National Rotavirus Vaccine Program: A Review. AB - BACKGROUND: Rotavirus vaccines created the opportunity to control diarrhea in children. We describe the rotavirus genotypes before and after the rotavirus vaccine introduction in Brazil. METHODS: We reviewed the distribution of rotavirus genotypes in Brazil before and after vaccine introduction by searching publication. RESULTS: Eighty-six studies reported 6884 (15.2%) rotavirus episodes among 45,305 children. Rotavirus caused 22.4% and 11.6% of cases before and after vaccine introduction. G1P[8], G9P[8] and G2P[4] heterotypic strains were most common before and after vaccine introduction. CONCLUSIONS: The vaccines may have selected heterotypic strains in this highly vaccinated population. PMID- 29189674 TI - Concurrent Community Transmission of Enterovirus D68 With Human Rhinoviruses and Respiratory Syncytial Virus Among Children in Sendai, Japan. AB - BACKGROUND: In the autumn of 2015, we experienced a surge in the number of pediatric cases of wheeze in our hospital, which was suspected to be caused by enterovirus (EV)-D68 transmission in the community. Thus, we implemented an ad hoc retrospective surveillance for EV-D68. METHODS: Patients <15 years of age with acute respiratory infection were eligible for inclusion in this study. All enrolled patients underwent virus detection test. Additionally, neutralization tests (NTs) were performed using the stored serum samples of the enrolled patients to compare the antigenicity of the virus isolated in this study with that isolated in 2010 and evaluate the anti-EV-D68 antibody prevalence. RESULTS: Respiratory syncytial virus (RSV) was the most commonly detected virus (35%), followed by EV-D68 (19%) and non-EV-D68 enteroviruses/human rhinoviruses (14%). Patients with EV-D68 infection had higher median age than those with RSV infection (P < 0.05). Moreover, patients with EV-D68 infection showed a higher expiratory wheeze prevalence than those with non-EV-D68 enterovirus/rhinovirus and RSV infections. The antigenicity of the isolate from the current study was similar to the virus that circulated in 2010. At the early study phase, children in our community did not have high NT titers, but the median log NT titer increased from 1.5 to 5 over time (P < 0.05). CONCLUSION: This study showed the concurrent circulation of EV-D68 with non-EV-D68 enteroviruses/rhinoviruses and RSV in infants and children in our community and captured the early stage of EV D68 transmission. PMID- 29189675 TI - Increasing Linezolid-resistant Enterococcus in a Children's Hospital. AB - We report a reduction in susceptibility to linezolid among Enterococcus isolates (98% in 2007 vs. 46% in 2014) in parallel with a 5-fold increase in linezolid use. A direct association could not be established as the majority of patients with linezolid nonsusceptible isolates did not have prior linezolid exposure. Nosocomial transmission of the nonsusceptible isolates could certainly have contributed. PMID- 29189676 TI - Disseminated Cryptococcosis With Severe Increased Intracranial Pressure Complicated With Cranial Nerve Palsy in a Child. AB - Cryptococcosis is less common in children than in adults but remains an important cause of pneumonia and meningoencephalitis in both immunocompromised and immunocompetent patients. Intracranial hypertension commonly complicates cryptococcal meningitis and may cause significant visual and neurologic morbidity and mortality. Early and aggressive management of intracranial hypertension in accordance with established guidelines reduces the risk of long-term complications and death. In this case report, we present a 12-year-old girl with cryptococcal meningitis, pneumonitis and dermatitis complicated with cranial nerve palsy and loss of vision. She was successfully treated with serial cerebrospinal fluid drainage, antifungal and interferon gamma therapy. PMID- 29189677 TI - Defining Study Outcomes That Better Reflect Individual Response to Treatment. AB - BACKGROUND: Most clinical trials comparing treatments evaluate the separate effects on each of several efficacy and toxicity outcomes. However, population averaged summary measures of treatment differences may not accurately reflect individual responses to treatment, and drawing conclusions about which treatment is "best" is straightforward if one treatment is superior across all outcomes, but challenging when this is not the case. METHODS: We created a study outcome based on expert opinion, which captures the risk/benefit profile of response to a treatment. Treatments were compared using this ordered outcome with standard statistical techniques. To illustrate the approach, we used as an example a study designed to evaluate initial antiretroviral therapy (ART) in human immunodeficiency virus-1-infected infants, in which results were contradictory across the study's primary and secondary efficacy and toxicity outcomes. The proposed risk/benefit outcome was evaluated retrospectively in each participant. RESULTS: In the International Maternal Pediatric Adolescent AIDS Clinical Trials P1060 study, one treatment regimen (lopinavir/ritonavir-based ART) was superior to the other (nevirapine-based ART) in reducing viral load (primary outcome) but inferior for immunologic and growth outcomes (important secondary outcomes in resource-limited settings). Treatment comparisons using the risk/benefit outcome indicated that the lopinavir/ritonavir-based ART regimen had a higher proportion of participants with the best overall response to treatment. Comparisons focusing on individual-level responses for the secondary outcomes also favored lopinavir/ritonavir-based ART, results that differed from the original population averaged analyses ones. CONCLUSIONS: Designing studies prospectively using risk/benefit outcomes focusing on an individual's responses to treatment more closely matches the needs of clinicians making decisions about how best to treat patients in clinical settings. PMID- 29189679 TI - Featured Articles for CME Credit December 2017. PMID- 29189678 TI - Attempting to validate the overtriage/undertriage matrix at a Level I trauma center. AB - BACKGROUND: The Optimal Resources Document mandates trauma activation based on injury mechanism, physiologic and anatomic criteria and recommends using the overtriage/undertriage matrix (Matrix) to evaluate the appropriateness of trauma team activation. The purpose of this study was to assess the effectiveness of the Matrix method by comparing patients appropriately triaged with those undertriaged. We hypothesized that these two groups are different, and Matrix does not discriminate the needs or outcomes of these different groups of patients. METHODS: Trauma registry data, from January 2013 to December 2015, at a Level I trauma center, were reviewed. Overtriage and undertriage rates were calculated by Matrix. Patients with Injury Severity Score (ISS) of 16 or greater were classified by activation level (full, limited, consultation), and triage category by Matrix. Patients in the limited activation and consultation groups were compared with patients with full activation by demographics, injuries, initial vital signs, procedures, delays to procedure, intensive care unit admission, length of stay, and mortality. RESULTS: Seven thousand thirty-one patients met activation criteria. Compliance with American College of Surgeons tiered activation criteria was 99%. The Matrix overtriage rate was 45% and undertriage was 24%. Of 2,282 patients with an ISS of 16 or greater, 1,026 were appropriately triaged (full activation), and 1,256 were undertriaged. Undertriaged patients had better Glasgow Coma Scale score, blood pressure, and base deficit than patients with full activation. Intensive care unit admission, hospital stays, and mortality were lower in the undertriaged group. The undertriaged group required fewer operative interventions with fewer delays to procedure. CONCLUSION: Despite having an ISS of 16 or greater, patients with limited activations were dissimilar to patients with full activation. Level of activation and triage are not equivalent. The American College of Surgeons Committee on Trauma full and tiered activation criteria are a robust means to have the appropriate personnel present based on the available prehospital information. Evaluation of the process of care, regardless of level of activation, should be used to evaluate trauma center performance. LEVEL OF EVIDENCE: Therapeutic and care management, level III.

Neural tube defects may occur as an isolated malformation, in combination with other malformations, as part of a genetic syndrome, or as a result of teratogenic exposure (1). Neural tube defects are the second-most-common major congenital anomaly (2) after cardiac malformations, and their prevalence varies by geographic region, race, and environmental factors (3). Outcomes and disabilities depend on level and extent of lesion; for instance, anencephaly is incompatible with life but most infants with spina bifida will survive after surgical repair (4). Importantly, and in contrast to many other congenital abnormalities, primary prevention of NTDs is possible with folic acid. In addition, prenatal screening and diagnosis are widely available, and fetal surgery has improved outcomes for some newborns. The purpose of this document is to provide information about NTDs and make management recommendations for the pregnancy complicated by a fetal NTD. PMID- 29189692 TI - Committee Opinion No. 726 Summary: Hospital Disaster Preparedness for Obstetricians and Facilities Providing Maternity Care. AB - Large-scale catastrophic events and infectious disease outbreaks highlight the need for disaster planning at all community levels. Features unique to the obstetric population (including antepartum, intrapartum, postpartum and neonatal care) warrant special consideration in the event of a disaster. Pregnancy increases the risks of untoward outcomes from various infectious diseases. Trauma during pregnancy presents anatomic and physiologic considerations that often can require increased use of resources such as higher rates of cesarean delivery. Recent evidence suggests that floods and human-influenced environmental disasters increase the risks of spontaneous miscarriages, preterm births, and low-birth weight infants among pregnant women. The potential surge in maternal and neonatal patient volume due to mass-casualty events, transfer of high-acuity patients, or redirection of patients because of geographic barriers presents unique challenges for obstetric care facilities. These circumstances require that facilities plan for additional increases in necessary resources and staffing. Although emergencies may be unexpected, hospitals and obstetric delivery units can prepare to implement plans that will best serve maternal and pediatric care needs when disasters occur. Clear designation of levels of maternal and neonatal care facilities, along with establishment of a regional network incorporating hospitals that provide maternity services and those that do not, will enable rapid transport of obstetric patients to the appropriate facilities, ensuring the right care at the right time. Using common terminology for triage and transfer and advanced knowledge of regionalization and levels of care will facilitate disaster preparedness.

PMID- 29189695 TI - Lymphoma Involving Skin and Subcutaneous Fat of the Breast: Two Cases. AB - Breast lymphoma is uncommon, and it usually involves breast parenchyma and ipsilateral axillary lymph nodes. We report rare cases of cutaneous T-cell lymphoma involving the skin and subcutaneous fat layers mimicking panniculitis of the breasts in a 33-year-old male patient who presented with a growing palpable mass and pain in both breasts and in 17-year-old female patient who presented with an indolent palpable breast mass for 1 year. Extranodal natural killer/T cell nasal-type and subcutaneous panniculitis-like T-cell lymphomas were diagnosed after skin punch biopsies. Here we report the clinical manifestations, mammographic and ultrasound findings, and the difficulties in histological diagnosis of the cases. PMID- 29189700 TI - Effectiveness of support groups to improve the quality of life of people with idiopathic pulmonary fibrosis a pre-post test pilot study. AB - BACKGROUND AND AIM OF THE WORK: Idiopathic Pulmonary Fibrosis (IPF) is an interstitial lung disease, which progressively leads to severe disability and death. The average survival expectancy, ranges from 3 to 5 years from diagnosis, and the available medicines do not lead to healing. The progression of IPF lead to a decline in forced vital capacity (FVC), dyspnea, cough, continuous sleep interruptions, resulting in increased fatigue and deteriorating quality of life (QOL), progressive limitation of daily life activities and social life, with repercussions on psychological and emotional well-being, aggravated by anxiety, loss of sense of self-confidence and depression. The aim of the study was to evaluate how the support groups influence the psychological well-being of people with IPF and their family members. METHODS: A pre-post test pilot study with a single group was conducted in a university hospital in Northern Italy, a centre for diagnosis and treatment of IPF. A support group was conducted by a nurse and entirely dedicated to people with IPF and their family members. Eighteen participants were enrolled in the support group. To measure the changes in psychological well-being was chosen the Psychological General Well-Being Index (PGWBI), which was administered at the time of enrolment to the group and after six months of attendance. RESULTS: Even if the effect is not statistically significant, the paired t-test showed that the participation in a support group conducted by a nurse, could increase psychological well-being in all of its dimensions: anxiety, depression, positivity, self-control, overall health, and vitality. CONCLUSIONS: Despite the null association, the increase of psychological well-being, closely related to the quality of life, indicates the need to further studies. In the absence of effective pharmacological treatments for healing, the support groups represent an opportunity for the wellbeing of the IPF patients and their caregivers. PMID- 29189701 TI - Expressive writing. A tool to help health workers. Research project on the benefits of expressive writing. AB - BACKGROUND AND AIMS: Numerous studies in the international literature hold that expressive writing is a useful tool to take care of the person as a whole. It gives voice to emotions, moods and intimate thoughts of patients, as well as caregivers and family members. The reference model is based on Pennebaker's theory (2004), which posits that expressing our deeper thoughts and feelings can result in significant health benefits in the short and long term. Studies over the past 25 years have shown that expressive writing, that is, simple writing on deeper thoughts and emotional sensations, is a useful tool to alleviate both physical and psychological symptoms. This research seeks to ascertain whether and how expressive writing has an impact on work satisfaction, coping strategies, and relational communication satisfaction of health practitioners. METHODS: a comparison was made between the expressive writing and neutral writing of two randomized groups of health care professionals. A group of 66 healthcare professionals participated in this study. They were evaluated pre- and post intervention using several scales and an ad hoc questionnaire, with one-month follow-up. RESULTS: After analyzing the texts, as in Pennebaker's studies, there was a reduction of words with negative emotion in the course of writing sessions. DISCUSSION: Expressive writing has a positive impact on adaptive coping strategies and work relational communication satisfaction. It also can facilitate the clarification and solution of various problems, increase cognitive abilities, and promote social interactions. PMID- 29189702 TI - Nurse training in self-management of patients with cardiovascular diseases: a multicentre observational study. AB - BACKGROUND AND AIM: The therapeutic education and self-management carried out by nurses, are winning elements in cardiovascular secondary prevention, but because they are complex matters, they require special training by the professionals. The target of the study has been to assess the effects in clinical practice of a training program for nurses in the management of patients with cardiovascular diseases, leaning towards a self-oriented patient management and therapeutic patient education. METHOD: The research utilized a quali-quantitative study to compare the responses of 53 trained nurses (experimental group) and 101 untrained nurses (control group). The instrument used was a self-report structured in two sections: the first, a qualitative kind, was used to investigate the portrayal of nurses regarding self-management; the second, a quantitative kind, included a Likert scale based on 5 points (1=never, 5=always) that investigated the professional nurse's action in its bio-psycho-socio-relational and clinical activities (La Sala, 2012). RESULTS: The trained nurses' approach is more oriented towards the psycho-socio-relational dimension, compared to the untrained nurses. A difference also emerged regarding activities of a bio clinical nature, which are performed much more by untrained nurses compared to trained professionals. CONCLUSIONS: The health education and self-management skills were used by trained nurses during their care of patients with cardiovascular diseases, stressing the importance for professional nurses to develop an integrated competence, using narrative talks as the main tool in a patient centred approach. PMID- 29189703 TI - The public perception of nurses. An Italian cross-sectional study. AB - BACKGROUND AND AIM: The public opinion about the nursing profession can influence health service users, the work performance of nurses, health policies, and the choice to become a nurse. The aim of this study was to investigate the perception of nursing in modern society. METHODS: A cross-sectional study was conducted with a sample of 398 participants belonging to four population groups: Very Important Persons (VIPs), general population, upper-school students, and nursing students. This phenomenon was assessed through the Nursing Attitude Questionnaire (NAQ) and several additional items. RESULTS: The results highlighted that general population and nursing students showed a significantly better image of nurses than did VIPs and upper-school students. CONCLUSIONS: Overall, the sample acknowledged nurses fundamental connotations and functions, although secondary school students poorly recognized nurses' professional autonomy, and VIPs' judgements seemed to be more sensitive to the image of nurses given by mass media. PMID- 29189704 TI - Preventing workplace incivility, lateral violence and bullying between nurses A narrative literature review. AB - : Introduction: according to available literature workplace incivility, lateral violence and bullying among nurses are widely diffused. Their negative consequences and the outcomes on nurses and healthcare organizations have been well described. However, real pro-active and reactive actions to manage these issues, seem to be poorly recognized and investigated. AIM: to summarize the results of international studies regarding the prevention of individual and collective reactions towards workplace incivility, lateral violence, and bullying between nurses. METHODS: a narrative literature review was performed. RESULTS: 7 original papers were included in this review. The implementation of zero tolerance policies and passive dissemination of information about these phenomena showed to be clearly ineffective. CONCLUSIONS: The limited number of evidence based studies and the typologies of interventions (mainly educational rather than team building programs and assertive communication) show inadequate effectiveness plus a lacking in the scientific evidence-based support. The need to find out innovative and "creative" solutions to face these problems has been suggested by different authors. PMID- 29189705 TI - Validation of the Italian version of the Critical Pain Observation Tool in brain injured critically ill adults. AB - BACKGROUND AND AIM: Pain in intensive care units (ICUs) is a frequent and often undermanaged problem. Brain-injured patients are often unable to reliably self report their pain, calling forth the need to use behavioural scales such as the Critical-Care Pain Observation Tool (CPOT). This study aimed to test the reliability and validity of the Italian CPOT use with brain-injured ICU adults. METHOD: A sample of 50 adults critical care patients was included. Each patient was assessed by two independent observers at three predefined times - at rest; during mobilization for hygiene; 20 minutes later - using the CPOT, PAINAD, and NRS. RESULTS: A good correlation was found between independent observers scores during painful procedure, establishing interrater reliability of CPOT. Criterion validation was supported by a strong correlation between CPOT and PAINAD scores, and a moderate relation between CPOT and NRS scores. The CPOT was able to discriminate between patients undergoing painful versus non-painful procedures. However, PAINAD performed better in this sample, as revealed by the comparison between the two AUC of ROC curves. CONCLUSIONS: The Italian CPOT use was found reliable and valid in this patient group. PMID- 29189706 TI - Unplanned Extubations in Intensive Care Unit: evidences for risk factors. A literature review. AB - BACKGROUND AND AIM: Unplanned extubations (UE) are getting more and more relevant in Critical Care, becoming a quality and care safeness outcome. This happens because after an UE the patient can face some complications concerning the airway management, respiratory and hemodynamic problems, lengthen in the hospital stay and in the mechanical ventilation time. The aim of this review is identify and classify the factors that could increase UE risk. METHODOLOGY: A systematic review of scientific articles was performed consulting the databases PubMed, Cinahl, Medline, EBSCOhost and Google Scholar. Articles from 2006 to 2011 were included. Pediatric Care settings were excluded. RESULTS: 21 articles were selected. From the results emerged that risk factors associated to the patient are widely controversial. Yet restlessness, a low level of sedation and a high level of consciousness seem to be highly related to UE. Organizational risk factors, as workload, nurse:patient ratio, and the use of interdisciplinary protocols seem to play an important role in UE. CONCLUSION: According the current literature, the research on UE still has to handle a wide uncertainty. There is the need for more studies developing conclusive evidences on the role of different risk factors. Anyway, literature highlights the importance of the nurse and of the healthcare system organization in reducing UE incidence. PMID- 29189707 TI - Management and effect of platelet-rich plasma on wound healing: small reality of Oglio Po Hospital. AB - Platelet Rich Plasma (PRP) represents a relatively new approach in regenerative medicine. Its use is increasing in the treatment of a variety of orthopedic conditions, such as the management of acute wounds, chronic non-healing lesions, acceleration of bone formation, tendinopathy and chondropathy. The Orthopaedic Unit at Oglio Po Hospital uses PRP Gel in wound care since 2008. More than 70 patients have been treated with this procedure. The aim of this study is to show our patients outcome. We present 3 cases of severe traumatic wound treated with our PRP protocol. The patients had complete healing of the lesion with good aesthetic results. PMID- 29189708 TI - Comparative Analysis of Soybean Root Proteome Reveals Molecular Basis of Differential Carboxylate Efflux under Low Phosphorus Stress. AB - Carboxylate efflux from roots is a crucial and differential response of soybean genotypes to low phosphorus (P) stress. Exudation of carboxylic acids including oxalate, citrate, succinate and fumarate was induced under low P stress, particularly in P-efficient soybean genotypes. Enhancement of root length, surface area and volume further improved P acquisition under low P stress. To understand the molecular basis of carboxylate efflux under low P stress, the root proteome of contrasting genotypes (P-efficient: EC-232019 and P-inefficient: EC 113396) was compared. Among a total of 325 spots, 105 (32%) were differentially abundant proteins (DAPs) between sufficient (250 uM) and low P (4 uM) levels. Abundance of 44 (14%) proteins decreased by more than two-fold under low P stress, while 61 (19%) proteins increased by more than two-fold. Protein identification and annotation revealed that the DAPs were involved in a myriad of functions including carboxylic acid synthesis, carbohydrate, protein and lipid metabolism. Proteins with significant abundance included malate dehydrogenase, isocitrate dehydrogenase, phosphoglucomutase, phosphoglycerate mutase, fructokinase, enolase, phosphoglycerate kinase, triosephosphate isomerase, alcohol dehydrogenase, glucan water dikinase, glutamine synthetase and argininosuccinate lyase. Inferences from proteomic analysis suggests the crosstalk between various metabolic pathways implicated in conferring superior P acquisition efficiency under stress. PMID- 29189709 TI - Non-Canonical Thinking for Targeting ALK-Fusion Onco-Proteins in Lung Cancer. AB - Anaplastic lymphoma kinase (ALK) gene rearrangements have been identified in lung cancer at 3-7% frequency, thus representing an important subset of genetic lesions that drive oncogenesis in this disease. Despite the availability of multiple FDA-approved small molecule inhibitors targeting ALK fusion proteins, drug resistance to ALK kinase inhibitors is a common problem in clinic. Thus, there is an unmet need to deepen the current understanding of genomic characteristics of ALK rearrangements and to develop novel therapeutic strategies that can overcome ALK inhibitor resistance. In this review, we present the genomic landscape of ALK fusions in the context of co-occurring mutations with other cancer-related genes, pointing to the central role of genetic epistasis (gene-gene interactions) in ALK-driven advanced-stage lung cancer. We discuss the possibility of targeting druggable domains within ALK fusion partners in addition to available strategies inhibiting the ALK kinase domain directly. Finally, we examine the potential of targeting ALK fusion-specific neoantigens in combination with other treatments, a strategy that could open a new avenue for the improved treatment of ALK positive lung cancer patients. PMID- 29189710 TI - Non-Additive Transcriptomic Responses to Inoculation with Rhizobia in a Young Allopolyploid Compared with Its Diploid Progenitors. AB - Root nodule symbioses (nodulation) and whole genome duplication (WGD, polyploidy) are both important phenomena in the legume family (Leguminosae). Recently, it has been proposed that polyploidy may have played a critical role in the origin or refinement of nodulation. However, while nodulation and polyploidy have been studied independently, there have been no direct studies of mechanisms affecting the interactions between these phenomena in symbiotic, nodule-forming species. Here, we examined the transcriptome-level responses to inoculation in the young allopolyploid Glycine dolichocarpa (T2) and its diploid progenitor species to identify underlying processes leading to the enhanced nodulation responses previously identified in T2. We assessed the differential expression of genes and, using weighted gene co-expression network analysis (WGCNA), identified modules associated with nodulation and compared their expression between species. These transcriptomic analyses revealed patterns of non-additive expression in T2, with evidence of transcriptional responses to inoculation that were distinct from one or both progenitors. These differential responses elucidate mechanisms underlying the nodulation-related differences observed between T2 and the diploid progenitors. Our results indicate that T2 has reduced stress-related transcription, coupled with enhanced transcription of modules and genes implicated in hormonal signaling, both of which are important for nodulation. PMID- 29189711 TI - Early Postoperative Low Expression of RAD50 in Rectal Cancer Patients Associates with Disease-Free Survival. AB - BACKGROUND: Molecular biomarkers have the potential to predict response to the treatment of rectal cancer. In this study, we aimed to evaluate the prognostic and clinicopathological implication of RAD50 (DNA repair protein RAD50 homolog) expression in rectal cancer. METHODS: A total of 266 rectal cancer patients who underwent surgery and received chemo- and radiotherapy between 2000 and 2011 were involved in the study. Postoperative RAD50 expression was determined by immunohistochemistry in surgical samples (n = 266). RESULTS: Using Kaplan-Meier survival analysis, we found that low RAD50 expression in postoperative samples was associated with worse disease free survival (p = 0.001) and overall survival (p < 0.001) in early stage/low-grade tumors. In a comparison of patients with low vs. high RAD50 expression, we found that low levels of postoperative RAD50 expression in rectal cancer tissues were significantly associated with perineural invasion (p = 0.002). CONCLUSION: Expression of RAD50 in rectal cancer may serve as a prognostic biomarker for long-term survival of patients with perineural invasion-positive tumors and for potential use in early stage and low-grade rectal cancer assessment. PMID- 29189712 TI - Genome-Wide Analysis Reveals the Secondary Metabolome in Streptomyces kanasensis ZX01. AB - Streptomyces kanasensis ZX01 produces some antibiotics and a glycoprotein with antiviral activity. To further evaluate its biosynthetic potential, here we sequenced the 7,026,279 bp draft genome of S. kanasensis ZX01 and analyzed all identifiable secondary gene clusters for controlling natural products. More than 60 putative clusters were found in S. kanasensis ZX01, the majority of these biosynthetic loci are novel. In addition, the regulators for secondary metabolism in S. kanasensis ZX01 were abundant. The global regulator nsdA not only controls biosynthesis of some antibiotics, but also enhances production of glycoprotein GP 1 with antiviral activity. This study importantly reveals the powerful interplay between genomic analysis and studies of traditional natural product purification/production increasing. PMID- 29189713 TI - Low Prevalence of Enzootic Equine Influenza Virus among Horses in Mongolia. AB - Horses are critically important for Mongolian herders' livelihoods, providing transportation and food products, and playing important cultural roles. Equine influenza virus (EIV) epizootics have been frequent among Mongolia's horses, with five occurring since 1970. We sought to estimate the prevalence for EIV infection among horses and Bactrian camels with influenza-like illness between national epizootics. In 2016-2017, active surveillance for EIV was periodically performed in four aimags (provinces). Nasal swabs were collected from 680 horses and 131 camels. Seven of the horse swabs were "positive" for qRT-PCR evidence of influenza A (Ct value <= 38). Two more were "suspect positive" (Ct value > 38 and <= 40). These nine specimens were collected from four aimags. None of the camel specimens had molecular evidence of infection. Despite serial blind passage in Madin-Darby Canine Kidney cells (MDCK) cells, none of the nine horse specimens yielded an influenza A virus. None of the 131 herder households surveyed had recently vaccinated their horses against EIV. It seems likely that sporadic EIV is enzootic in multiple Mongolian aimags. This finding, the infrequent use of EIV vaccination, periodic prevalence of highly pathogenic avian influenza, and the mixing of domestic and wild equid herds suggest that Mongolia may be a hot spot for novel EIV emergence. PMID- 29189714 TI - The Morphologies of the Semiconductor Oxides and Their Gas-Sensing Properties. AB - Semiconductor oxide chemoresistive gas sensors are widely used for detecting deleterious gases due to low cost, simple preparation, rapid response and high sensitivity. The performance of gas sensor is greatly affected by the morphology of the semiconductor oxide. There are many semiconductor oxide morphologies, including zero-dimensional, one-dimensional, two-dimensional and three dimensional ones. The semiconductor oxides with different morphologies significantly enhance the gas-sensing performance. Among the various morphologies, hollow nanostructures and core-shell nanostructures are always the focus of research in the field of gas sensors due to their distinctive structural characteristics and superior performance. Herein the morphologies of semiconductor oxides and their gas-sensing properties are reviewed. This review also proposes a potential strategy for the enhancement of gas-sensing performance in the future. PMID- 29189715 TI - Microbial Risk Assessment of Tidal-Induced Urban Flooding in Can Tho City (Mekong Delta, Vietnam). AB - Public health risks from urban flooding are a global concern. Contaminated floodwater may expose residents living in cities as they are in direct contact with the water. However, the recent literature does not provide much information about this issue, especially for developing countries. In this paper, the health risk due to a flood event occurred in Can Tho City (Mekong Delta, Vietnam) on 7 October 2013 was investigated. The Quantitative Microbial Risk Assessment method was used in this study. The data showed that the pathogen concentrations were highly variable during the flood event and exceeded water standards for surface water. Per 10,000 people in contact with the floodwater, we found Salmonella caused the highest number of infections to adults and children (137 and 374, respectively), while E. coli caused 4 and 12 cases, per single event, respectively. The results show that further investigations on health risk related to flood issues in Can Tho City are required, especially because of climate change and urbanization. In addition, activities to raise awareness- about floods, e.g., "living with floods", in the Mekong Delta should also consider health risk issues. PMID- 29189717 TI - Telomere Shortening in Hematological Malignancies with Tetraploidization-A Mechanism for Chromosomal Instability? AB - Aneuploidy, the presence of an abnormal number of chromosomes in a cell, is one of the most obvious differences between normal and cancer cells. There is, however, debate on how aneuploid cells arise and whether or not they are a cause or a consequence of tumorigenesis. Further, it is important to distinguish aneuploidy (the "state" of the karyotype) from chromosomal instability (CIN; the "rate" of karyotypic change). Although CIN leads to aneuploidy, not all aneuploid cells exhibit CIN. One proposed route to aneuploid cells is through an unstable tetraploid intermediate because tetraploidy promotes chromosomal aberrations and tumorigenesis. Tetraploidy or near-tetraploidy (T/NT) (81-103 chromosomes) karyotypes with or without additional structural abnormalities have been reported in acute leukemia, T-cell and B-cell lymphomas, and solid tumors. In solid tumors it has been shown that tetraploidization can occur in response to loss of telomere protection in the early stages of tumorigenesis in colon cancer, Barrett's esophagus, and breast and cervical cancers. In hematological malignancies T/NT karyotypes are rare and the role of telomere dysfunction for the induction of tetraploidization is less well characterized. To further our understanding of possible telomere dysfunction as a mechanism for tetrapolydization in hematological cancers we here characterized the chromosomal complement and measured the telomere content by interphase nuclei quantitative fluorescence in situ hybridization (iQFISH) in seven hematological cancer patients with T/NT karyotypes, and after cytogenetic remission. The patients were identified after a search in our local cytogenetic registry in the 5-year period between June 2012 and May 2017 among more than 12,000 analyzed adult patients in this period. One advantage of measuring telomere content by iQFISH is that it is a single-cell analysis so that the telomere content can be distinguished between normal karyotype cells and cells with T/NT karyotypes. We find that the telomeres are particularly short in cells with T/NT karyotypes as compared with normal cells, and in T/NT karyotypes harboring additional chromosomal aberrations as well. These findings suggest that telomere dysfunction in hematological malignancies may be a mechanism for tetraploidization and CIN. PMID- 29189716 TI - Recent Advances in Nucleic Acid Targeting Probes and Supramolecular Constructs Based on Pyrene-Modified Oligonucleotides. AB - In this review, we summarize the recent advances in the use of pyrene-modified oligonucleotides as a platform for functional nucleic acid-based constructs. Pyrene is of special interest for the development of nucleic acid-based tools due to its unique fluorescent properties (sensitivity of fluorescence to the microenvironment, ability to form excimers and exciplexes, long fluorescence lifetime, high quantum yield), ability to intercalate into the nucleic acid duplex, to act as a pi-pi-stacking (including anchoring) moiety, and others. These properties of pyrene have been used to construct novel sensitive fluorescent probes for the sequence-specific detection of nucleic acids and the discrimination of single nucleotide polymorphisms (SNPs), aptamer-based biosensors, agents for binding of double-stranded DNAs, and building blocks for supramolecular complexes. Special attention is paid to the influence of the design of pyrene-modified oligonucleotides on their properties, i.e., the structure-function relationships. The perspectives for the applications of pyrene modified oligonucleotides in biomolecular studies, diagnostics, and nanotechnology are discussed. PMID- 29189718 TI - Elucidating the Skin Delivery of Aglycone and Glycoside Flavonoids: How the Structures Affect Cutaneous Absorption. AB - Flavonoids are bioactive phytochemicals that exhibit protective potential against cutaneous inflammation and photoaging. We selected eight flavonoid aglycones or glycosides to elucidate the chemistry behind their skin absorption capability through experimental and computational approaches. The skin delivery was conducted using nude mouse and pig skins mounted on an in vitro Franz cell assembly. The anti-inflammatory activity was examined using the O2*. PMID- 29189720 TI - Fabrication and Mechanical Behavior of Ex Situ Mg-Based Bulk Metallic Glass Matrix Composite Reinforced with Electroless Cu-Coated SiC Particles. AB - Magnesium-based bulk metallic glass matrix composites (BMGMCs) have better plasticity than the corresponding bulk metallic glasses (BMGs); however, their strength and density are often compromised due to the fact that the effective reinforcement phase is mostly plastic heavy metal. For lightweight SiC-particle reinforced BMGMCs, interface wettability and the sharpness of the particles often reduce the strengthening effect. In this work, SiC particles were coated with a thin Cu coating by electroless plating, and added to Mg54Cu26.5Ag8.5Gd11 melt in an amount of 5 wt % to prepare a BMGMC. The microstructure of the interface, mechanical behavior and fracture morphology of the BMGMC were studied by scanning electron microscopy and quasi-static compression testing. The results showed that the Cu coating improved the wettability between SiC and the matrix alloy without obvious interfacial reactions, leading to the dispersion of SiC particles in the matrix. The addition of Cu-coated SiC particles improved the plastic deformation ability of Mg54Cu26.5Ag8.5Gd11 BMG, proving that electroless plating was an effective method for controlling the interface microstructure and mechanical behavior of BMGMCs. PMID- 29189719 TI - Transcriptional and Hormonal Regulation of Weeping Trait in Salix matsudana. AB - Salix matsudana is a large and rapidly-growing tree, with erect or spreading branchlets (upright willow). However, S. matsudana var. pseudomatsudana is one of the varietas, with pendulous branchlets (weeping willow). It has high ornamental value for its graceful pendulous branches. In order to study the molecular basis for this weeping trait, leaves and stems collected at different developmental stages were analyzed using RNA-seq coupled with digital gene expression. Although weeping trees are used worldwide as landscape plants, little is known about the genes that control weeping. Our growth results indicated that branches in weeping willow developed and elongated throughout all developmental stages, but branches in upright willow grew rapidly in the initial stages and then grew slowly and began shoot branching in the middle stages. A total of 613 hormone-related genes were differentially expressed in willow development. Among these, genes associated with auxin and gibberellin (GA) were highly likely to be responsible for the weeping trait, and genes associated with auxin and ethylene probably play crucial roles in shoot elongation. The genes with differential expression patterns were used to construct a network that regulated stem development, and auxin-related genes were identified as hub genes in the network in the weeping willow. Our results suggest an important role of gibberellin and auxin in regulating the weeping trait in Salix matsudana. This is the first report on the molecular aspects of hormonal effects on weeping trait in willow using transcriptomics and helps in dissecting the molecular mechanisms by which the weeping trait is controlled. PMID- 29189721 TI - Evaluation of Surface Cleaning Procedures for CTGS Substrates for SAW Technology with XPS. AB - A highly efficient and reproducible cleaning procedure of piezoelectric substrates is essential in surface acoustic waves (SAW) technology to fabricate high-quality SAW devices, especially for new applications such SAW sensors wherein new materials for piezoelectric substrates and interdigital transducers are used. Therefore, the development and critical evaluation of cleaning procedures for each material system that is under consideration becomes crucial. Contaminants like particles or the presence of organic/inorganic material on the substrate can dramatically influence and alter the properties of the thin film substrate composite, such as wettability, film adhesion, film texture, and so on. In this article, focus is given to different cleaning processes like SC-1 and SC 2, UV-ozone treatment, as well as cleaning by first-contact polymer Opticlean, which are applied for removal of contaminants from the piezoelectric substrate Ca 3 TaGa 3 Si 2 O 14 . By means of X-ray photoelectron spectroscopy, the presence of the most critical contaminants such as carbon, sodium, and iron removed through different cleaning procedures were studied and significant differences were observed between the outcomes of these procedures. Based on these results, a two-step cleaning process, combining SC-1 at a reduced temperature at 30 ? C instead of 80 ? C and a subsequent UV-ozone cleaning directly prior to deposition of the metallization, is suggested to achieve the lowest residual contamination level.

AB - In this paper, we propose a new algorithm to reconstruct optics surfaces (aka wavefronts) from gradients, defined on a circular domain, by means of the Spherical Harmonics. The experimental results indicate that this algorithm renders the same accuracy, compared to the reconstruction based on classical Zernike polynomials, using a smaller number of polynomial terms, which potentially speeds up the wavefront reconstruction. Additionally, we provide an open-source C++ library, released under the terms of the GNU General Public License version 2 (GPLv2), wherein several polynomial sets are coded. Therefore, this library constitutes a robust software alternative for wavefront reconstruction in a high energy laser field, optical surface reconstruction, and, more generally, in surface reconstruction from gradients. The library is a candidate for being integrated in control systems for optical devices, or similarly to be used in ad hoc simulations. Moreover, it has been developed with flexibility in mind, and, as such, the implementation includes the following features: (i) a mock-up generator of various incident wavefronts, intended to simulate the wavefronts commonly encountered in the field of high-energy lasers production; (ii) runtime selection of the library in charge of performing the algebraic computations; (iii) a profiling mechanism to measure and compare the performance of different steps of the algorithms and/or third-party linear algebra libraries. Finally, the library can be easily extended to include additional dependencies, such as porting the algebraic operations to specific architectures, in order to exploit hardware acceleration features.

AB - The primordial Earth probably had most of the factors needed for the emergence and development of life. It is believed that it had not only water, but also simple inorganic and organic materials. While studies since the 1950s on the origins of organic matter have established key roles for amino acids, conditions that would have promoted their condensation to make polymers, such as peptides or proteins, have yet to be fully defined. The condensation of amino acids in a water-rich environment is not thermodynamically favored. Therefore, the efficient formation of peptides requires the presence of a catalyst or the activation of a substrate. In living cells, the biosynthesis of proteins is assisted by enzymes and requires adenosine triphosphate (ATP), a relatively complex organic polyphosphate, which serves as an energy source. Outside the living organism, simpler inorganic polyphosphates can form active aminoacyl-phosphate anhydrides, which suggests the broader potential of phosphorus for enabling the polymerization of amino acids. However, this has yet to be demonstrated. To address this gap, aqueous solutions containing a simple dipeptide, diglycine, and a simple polyphosphate, trimetaphosphate, were dried, and reaction products were analyzed by high performance liquid chromatography and mass spectrometry (HPLC MS). Different reaction environments, which were defined by the initial solution composition, pH, temperature, and incubation time, were found to affect the distribution and yield of products. Our results collectively provide strong evidence for reactions that both condense and hydrolyze peptides. It is noteworthy that the co-occurrence of reactions that form and cleave peptides are a central feature of Kauffman's theory for the emergence of autocatalytic sets, which is a key step in the chemical origins of life. PMID- 29189725 TI - Laser Scanning Confocal Thermoreflectance Microscope for the Backside Thermal Imaging of Microelectronic Devices. AB - In this paper, we report on a confocal thermoreflectance imaging system that can examine the thermal characteristics of microelectronic devices by penetrating the backside of a device through the substrate. In this system, the local reflectivity variations due to heat generation in the device are measured point by point by a laser scanning confocal microscope capable of eliminating out-of focus reflections and the thermoreflectance is extracted via Fourier-domain signal processing. In comparison to the conventional widefield thermoreflectance microscope, the proposed laser scanning confocal thermoreflectance microscope improves the thermoreflectance sensitivity by ~23 times and the spatial resolution by ~25% in backside thermoreflectance measurements. PMID- 29189723 TI - Long Non-Coding RNAs in Metabolic Organs and Energy Homeostasis. AB - Single cell organisms can surprisingly exceed the number of human protein-coding genes, which are thus not at the origin of the complexity of an organism. In contrast, the relative amount of non-protein-coding sequences increases consistently with organismal complexity. Moreover, the mammalian transcriptome predominantly comprises non-(protein)-coding RNAs (ncRNA), of which the long ncRNAs (lncRNAs) constitute the most abundant part. lncRNAs are highly species- and tissue-specific with very versatile modes of action in accordance with their binding to a large spectrum of molecules and their diverse localization. lncRNAs are transcriptional regulators adding an additional regulatory layer in biological processes and pathophysiological conditions. Here, we review lncRNAs affecting metabolic organs with a focus on the liver, pancreas, skeletal muscle, cardiac muscle, brain, and adipose organ. In addition, we will discuss the impact of lncRNAs on metabolic diseases such as obesity and diabetes. In contrast to the substantial number of lncRNA loci in the human genome, the functionally characterized lncRNAs are just the tip of the iceberg. So far, our knowledge concerning lncRNAs in energy homeostasis is still in its infancy, meaning that the rest of the iceberg is a treasure chest yet to be discovered.

AB - In order to develop a novel biofungicide, the antifungal activity and action mode of cuminic acid from the seed of Cuminum cyminum L. against Fusarium oxysporum f. sp. niveum (FON) on watermelon was determined systematically. In this study, the median effective concentration (EC50) value for cuminic acid in inhibiting mycelial growth of FON was 22.53 MUg/mL. After treatment with cuminic acid, the mycelial morphology was seriously influenced; cell membrane permeability and glycerol content were increased markedly, but pigment and mycotoxin (mainly fusaric acid) were significantly decreased. Synthesis genes of bikaverin (Bike1, Bike2 and Bike3) and fusaric acid (FUB1, FUB2, FUB3 and FUB4) both were downregulated compared with the control, as confirmed by quantitative RT-PCR. In greenhouse experiments, cuminic acid at all concentrations displayed significant bioactivities against FON. Importantly, significant enhancement of activities of SOD, POD, CAT and decrease of MDA content were observed after in vivo cuminic acid treatment on watermelon leaves. These indicated that cuminic acid not only showed high antifungal activity, but also could enhance the self-defense system of the host plant. Above all, cuminic acid showed the potential as a biofungicide to control FON.

AB - We describe the clinical course of a 60-year old male admitted with Staphylococcus aureus bacteremia and back-pain. The patient was suspected of having spondylitis and treated as such with antibiotics; however, both fluorine 18 fluoro-2-deoxy-d-glucose (18F-FDG) positron-emission tomography and magnetic resonance imaging (MRI) with iv contrast showed significant inflammation of muscles and subcutaneous soft tissue in relation to the patients back and left shoulder, but no signs of the working diagnosis of spondylitis. The unusual location of the infection was not explained until a few days prior to being discharged when the patient reported visits to a local physiotherapist where he would have acupuncture performed for non-specific back pain. His last acupunctural procedure had been performed 6 days prior to admission. This case is, to our knowledge, the first to show muscular inflammation on both 18-F-FDG PET/CT and MRI following acupuncture due to S. aureus. This case highlights the need for clinicians to search for alternative explanations when imaging does not support the diagnosis. PMID- 29189728 TI - Proton Radiation Effects on Dark Signal Distribution of PPD CMOS Image Sensors: Both TID and DDD Effects. AB - Four-transistor (T) pinned photodiode (PPD) CMOS image sensors (CISs) with four megapixel resolution using 11um pitch high dynamic range pixel were radiated with 3 MeV and 10MeV protons. The dark signal was measured pre- and post-radiation, with the dark signal post irradiation showing a remarkable increase. A theoretical method of dark signal distribution pre- and post-radiation is used to analyze the degradation mechanisms of the dark signal distribution. The theoretical results are in good agreement with experimental results. This research would provide a good understanding of the proton radiation effects on the CIS and make it possible to predict the dark signal distribution of the CIS under the complex proton radiation environments. PMID- 29189729 TI - Sugar-Sweetened Beverage Consumption and Risks of Obesity and Hypertension in Chinese Children and Adolescents: A National Cross-Sectional Analysis. AB - We investigated the consumption of sugar-sweetened beverage (SSB) and its association with obesity and hypertension in a national sample of children and adolescents in China, where many low- and middle-income families live. Data were obtained from a 2014 national intervention program against obesity in Chinese children and adolescents aged 6-17 years. Height, weight, waist circumference, and blood pressure were measured. Information of SSB consumption, socioeconomic status, dietary intake, screen time, and physical activity were self-reported. Multivariate logistic regression was used to assess the association of SSB consumption with obesity and hypertension. A total of 66.6% of the 53,151 participants reported consuming SSB. The per capita and per consumer SSB intake were 2.84 +/- 5.26 servings/week and 4.26 +/- 5.96 servings/week, respectively. Boys, older children, and adolescents, and individuals with long screen time or high physical activity or low parental education level were more likely to consume SSB. Participants who were high SSB consumers had a higher odds ratio (1.133, 95% CI: 1.054-1.217) than non-consumers for having abdominal obesity after adjustment for age, sex, residence, socioeconomic status, diet, screen time, and physical activity. However, SSB consumption was not associated with general obesity or hypertension in children and adolescents. In conclusion, more than half of the children and adolescents in China consumed SSB, which was independently related to a high risk of abdominal obesity. The results of this study indicated that SSB reduction strategies and policies may be useful in preventing obesity among Chinese children and adolescents. PMID- 29189730 TI - A New Series of Pyrrole-Based Chalcones: Synthesis and Evaluation of Antimicrobial Activity, Cytotoxicity, and Genotoxicity. AB - In an effort to develop new potent antimicrobial and anticancer agents, new pyrrole-based chalcones were designed and synthesized via the base-catalyzed Claisen-Schmidt condensation of 2-acetyl-1-methylpyrrole with 5-(aryl)furfural derivatives. The compounds were evaluated for their in vitro antimicrobial effects on pathogenic bacteria and Candida species using microdilution and ATP luminescence microbial cell viability assays. MTT assay was performed to determine the cytotoxic effects of the compounds on A549 human lung adenocarcinoma, HepG2 human hepatocellular carcinoma, C6 rat glioma, and NIH/3T3 mouse embryonic fibroblast cell lines. 1-(1-Methyl-1H-pyrrol-2-yl)-3-(5-(4 chlorophenyl)furan-2-yl)prop-2-en-1-one (7) and 1-(1-methyl-1H-pyrrol-2-yl)-3-(5 (2,5-dichlorophenyl)furan-2-yl)prop-2-en-1-one (9) were found to be the most potent antifungal agents against Candida krusei and therefore these compounds were chosen for flow cytometry analysis and Ames MPF assay. ATP bioluminescence assay indicated that the antifungal activity of compounds 7 and 9 against C. krusei was significantly higher than that of other compounds and the reference drug (ketoconazole), whereas flow cytometry analysis revealed that the percentage of dead cells treated with compound 7 was more than that treated with compound 9 and ketoconazole. According to Ames MPF assay, compounds 7 and 9 were found to be non-genotoxic against TA98 and TA100 with/without metabolic activation. MTT assay indicated that 1-(1-methyl-1H-pyrrol-2-yl)-3-(5-(2-nitrophenyl)furan-2-yl)prop-2 en-1-one (3) showed more selective anticancer activity than cisplatin against the HepG2 cell line. On the other hand, 1-(1-methyl-1H-pyrrol-2-yl)-3-(5-(4 nitrophenyl)furan-2-yl)prop-2-en-1-one (1) was found to be more effective and selective on the A549 cell line than cisplatin. PMID- 29189731 TI - Differential Effects of Superoxide Dismutase Mimetics after Mechanical Overload of Articular Cartilage. AB - Post-traumatic osteoarthritis can develop as a result of the initial mechanical impact causing the injury and also as a result of chronic changes in mechanical loading of the joint. Aberrant mechanical loading initiates excessive production of reactive oxygen species, oxidative damage, and stress that appears to damage mitochondria in the surviving chondrocytes. To probe the benefits of increasing superoxide removal with small molecular weight superoxide dismutase mimetics under severe loads, we applied both impact and overload injury scenarios to bovine osteochondral explants using characterized mechanical platforms with and without GC4403, MnTE-2-PyP, and MnTnBuOE-2-PyP. In impact scenarios, each of these mimetics provides some dose-dependent protection from cell death and loss of mitochondrial content while in repeated overloading scenarios only MnTnBuOE-2 PyP provided a clear benefit to chondrocytes. These results support the hypothesis that superoxide is generated in excess after impact injuries and suggest that superoxide production within the lipid compartment may be a critical mediator of responses to chronic overload. This is an important nuance distinguishing roles of superoxide, and thus superoxide dismutases, in mediating damage to cellular machinery in hyper-acute impact scenarios compared to chronic scenarios. PMID- 29189732 TI - Identification and Characterization of Hyphantria cunea Aminopeptidase N as a Binding Protein of Bacillus thuringiensis Cry1Ab35 Toxin. AB - The fall webworm, Hyphantria cunea (Drury) is a major invasive pest in China. Aminopeptidase N (APN) isoforms in lepidopteran larvae midguts are known for their involvement in the mode of action of insecticidal crystal (Cry) proteins from Bacillus thuringiensis. In the present work, we identified a putative Cry1Ab toxin-binding protein, an APN isoform designated HcAPN3, in the midgut of H. cunea by ligand blot and mass spectrometry. HcAPN3 was highly expressed throughout all larval developmental stages and was abundant in the midgut and hindgut tissues. HcAPN3 was down-regulated at 6 h, then was up-regulated significantly at 12 h and 24 h after Cry1Ab toxin treatment. We expressed HcAPN3 in insect cells and detected its interaction with Cry1Ab toxin by ligand blot assays. Furthermore, RNA interference (RNAi) against HcAPN3 using oral delivery and injection of double-stranded RNA (dsRNA) resulted in a 61-66% decrease in transcript level. Down-regulating of the expression of HcAPN3 was closely associated with reduced susceptibility of H. cunea to Cry1Ab. In addition, the HcAPN3E fragment peptide expressed in Escherichia coli enhanced Cry1Ab toxicity against H. cunea larvae. This work represents the first evidence to suggest that an APN in H. cunea is a putative binding protein involved in Cry1Ab susceptibility. PMID- 29189733 TI - Surface Modification of Carbon Nanotubes with an Enhanced Antifungal Activity for the Control of Plant Fungal Pathogen. AB - The addition of surface functional groups to multi-walled carbon nanotubes (MWCNTs) expands their application in engineering, materials, and life science. In the study, we explored the antifungal activities of MWCNTs with different surface groups against an important plant pathogenic fungi Fusarium graminearum. All of the OH-, COOH-, and NH2-modified MWCNTs showed enhanced inhibition in spore elongation and germination than the pristine MWCNTs. The length of spores decreased by almost a half from 54.5 MUm to 28.3, 27.4, and 29.5 MUm, after being treated with 500 MUg.mL-1 MWCNTs-COOH, MWCNTs-OH, and MWCNTs-NH2 separately. Furthermore, the spore germination was remarkably inhibited by surface-modified MWCNTs, and the germination rate was only about 18.2%, three times lower than pristine MWCNTs. The possible antifungal mechanism of MWCNTs is also discussed. Given the superior antifungal activity of surface modified MWCNTs and the fact that MWCNTs can be mass-produced with facile surface modification at low cost, it is expected that this carbon nanomaterial may find important applications in plant protection. PMID- 29189734 TI - Fabrication and Characterization of Porous MgAl2O4 Ceramics via a Novel Aqueous Gel-Casting Process. AB - A novel and aqueous gel-casting process has been successfully developed to fabricate porous MgAl2O4 ceramics by using hydratable alumina and MgO powders as raw materials and deionized water as hydration agent. The effects of different amounts of deionized water on the hydration properties, apparent porosity, bulk density, microstructure, pore size distribution and compressive strength of the samples were investigated. The results indicated that the porosity and the microstructure of porous MgAl2O4 ceramics were governed by the amounts of deionized water added. The porous structure was formed by the liberation of physisorbed water and the decomposition of hydration products such as bayerite, brucite and boehmite. After determining the addition amounts of deionized water, the fabricated porous MgAl2O4 ceramics had a high apparent porosity (52.5-65.8%), a small average pore size structure (around 1-3 MUm) and a relatively high compressive strength (12-28 MPa). The novel aqueous gel-casting process with easy access is expected to be a promising candidate for the preparation of Al2O3-based porous ceramics. PMID- 29189735 TI - Effects of Omega-3 Long Chain Polyunsaturated Fatty Acid Supplementation on Cardiovascular Mortality: The Importance of the Dose of DHA. AB - Recent evidence on the relationship between omega-3 long chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation and cardiovascular health suggests that n 3 LCPUFA may no longer be efficacious. This review summarises the randomised controlled trials (RCTs) that assess the effect of n-3 LCPUFA supplementation on cardiovascular mortality. It appears that in the RCTs that showed no effect of n 3 LCPUFA on cardiovascular mortality, the dose of n-3 LCPUFA (in particular docosahexaenoic acid (DHA)) and hence the n-3 LCPUFA status, may not have been sufficiently high to demonstrate the efficacy, and/or the baseline n-3 LCPUFA status was already too high. The intention-to-treat analysis (ITT) is the gold standard for analysing RCTs and ITT is used for drug intervention trials where exposure to the drug versus no drug exposure provides two clearly distinct groups to determine the efficacy of the drug being studied. This differs in nutrition trials as often the nutrient of interest being studied is already being consumed by both groups (placebo and active) and therefore a true placebo group with absolutely no intake of the nutrient being studied is highly unlikely. Therefore, in n-3 LCPUFA supplementation trials, as there is no clear distinction between the two groups (placebo and n-3 LCPUFA), a per-protocol analysis (comparison of groups that includes only those participants that fully completed the original intervention allocation) should be conducted in addition to ITT analysis. Furthermore, blood analysis pre- and post-supplementation should be conducted to ensure that: (1) that the baseline n-3 status is not too high, in order to alleviate a potential ceiling effect; and (2) that the dose is high enough and hence the increase in omega-3 status will be high enough in order to assess the efficacy of n-3 LCPUFA supplementation.

PMID- 29189737 TI - Novel Artificial Tears Containing Cross-Linked Hyaluronic Acid: An In Vitro Re Epithelialization Study. AB - Dry eye syndrome is a common disease which can damage the corneal epithelium. It is treated with eye drops to stimulate tear production and hydrate the corneal surface. The most prescribed artificial tear remedies contain hyaluronic acid (HA), which enhances epithelial wound healing, improving tissue health. To the best of our knowledge, only a few recent studies have investigated cross-linked HA (HA-CL) in eye drops for human applications. This work consists in an in vitro evaluation of the re-epithelialization ability of two different preparations containing a recently synthetized HA cross-linked with urea: 0.02% (w/v) HA-CL (solution 1, S1), and 0.4% (w/v) HA-CL (solution 2, S2). The study was conducted on both 2D human corneal cells (HCEpiC) and 3D reconstructed tissues of human corneal epithelium (HCE). Viability by 3(4,5-dimethylthiazol-2)2,5 diphenyltetrazolium bromide (MTT) test, pro-inflammatory cytokine release (interleukin-8, IL-8) by ELISA, and morphology by hematoxylin and eosin (HE) staining were evaluated. In addition, to understand the molecular basis of the re epithelialization properties, cyclin D1 levels were assessed by western blot. The results showed no cellular toxicity, a slight decrease in IL-8 release, and restoration of epithelium integrity when the wounded 3D model was treated with S1 and S2. In parallel, cyclin D1 levels increased in cells treated with both S1 and S2. PMID- 29189739 TI - Small Gold Nanorods: Recent Advances in Synthesis, Biological Imaging, and Cancer Therapy. AB - Over the past few decades, the synthetic development of ultra-small nanoparticles has become an important strategy in nano-medicine, where smaller-sized nanoparticles are known to be more easily excreted from the body, greatly reducing the risk caused by introducing nano-theranostic agents. Gold nanorods are one of the most important nano-theranostic agents because of their special optical and electronic properties. However, the large size (diameter > 6 nm) of most obtained gold nanorods limits their clinical application. In recent years, more and more researchers have begun to investigate the synthesis and application of small gold nanorods (diameter < 6 nm), which exhibit similar optical and electronic properties as larger gold nanorods. In this review, we summarize the recent advances of synthesis of the small gold nanorods and their application for near-infrared light-mediated bio-imaging and cancer therapy. PMID- 29189738 TI - Aging Gut Microbiota at the Cross-Road between Nutrition, Physical Frailty, and Sarcopenia: Is There a Gut-Muscle Axis? AB - Inadequate nutrition and physical inactivity are the mainstays of primary sarcopenia-physiopathology in older individuals. Gut microbiota composition is strongly dependent on both of these elements, and conversely, can also influence the host physiology by modulating systemic inflammation, anabolism, insulin sensitivity, and energy production. The bacterial metabolism of nutrients theoretically influences skeletal muscle cell functionality through producing mediators that drive all of these systemic effects. In this study, we review the scientific literature supporting the concept of the involvement of gut microbiota in primary sarcopenia physiopathology. First, we examine studies associating fecal microbiota alterations with physical frailty, i.e., the loss of muscle performance and normal muscle mass. Then, we consider studies exploring the effects of exercise on gut microbiota composition. Finally, we examine studies demonstrating the possible effects of mediators produced by gut microbiota on skeletal muscle, and intervention studies considering the effects of prebiotic or probiotic administration on muscle function. Even if there is no evidence of a distinct gut microbiota composition in older sarcopenic patients, we conclude that the literature supports the possible presence of a "gut-muscle axis", whereby gut microbiota may act as the mediator of the effects of nutrition on muscle cells. PMID- 29189740 TI - Aptamers and Glioblastoma: Their Potential Use for Imaging and Therapeutic Applications. AB - Glioblastoma is a highly aggressive primary brain tumour, renowned for its infiltrative growth and varied genetic profiles. The current treatment options are insufficient, and their off-target effects greatly reduce patient quality of life. The major challenge in improving glioblastoma diagnosis and treatment involves the development of a targeted imaging and drug delivery platform, capable of circumventing the blood brain barrier and specifically targeting glioblastoma tumours. The unique properties of aptamers demonstrate their capability of bridging the gap to the development of successful diagnosis and treatment options, where antibodies have previously failed. Aptamers possess many characteristics that make them an ideal novel imaging and therapeutic agent for the treatment of glioblastoma and other brain malignancies, and are likely to provide patients with a better standard of care and improved quality of life. Their target sensitivity, selective nature, ease of modification and low immunogenicity make them an ideal drug-delivery platform. This review article summarises the aptamers previously generated against glioblastoma cells or its identified biomarkers, and their potential application in diagnosis and therapeutic targeting of glioblastoma tumours. PMID- 29189741 TI - The Antitumor Constituents from Hedyotis Diffusa Willd. AB - As a TCM, Hedyotis diffusa Willd. has been using to treat malignant tumors, and many studies also showed that the extracts from Hedyotis diffusa Willd. possessed evident antitumor activities. Therefore, we carried out chemical study on Hedyotis diffusa Willd. and investigated the cytotoxicity of the obtained compounds on a panel of eight tumor cell lines. As a result, four new compounds were isolated from Hedyotis diffusa Willd., including three iridoid glycosides of Shecaoiridoidside A-C (1-3) and a cerebroside of shecaocerenoside A (4). Also, six known iridoid compounds (5-10) were also obtained. The cytotoxicity of all compounds against human tumor cell lines of HL-60, HeLa, HCT15, A459, HepG2, PC 3, CNE-2, and BCG-823 were also evaluated in vitro. New compound 3 exhibited evident cytotoxicity to all tumor cell lines except the Hela, and the IC50 values are from 9.6 uM to 62.2 uM, while new compound 4 showed moderate cytotoxicity to all the cell lines, and the IC50 values are from 33.6 uM to 89.3 uM. By contrast, new compound 1 and known compound 9 showed moderate cytotoxicity to HCT15, A459, and HepG2 selectively. Known compound 7 also exhibited moderate cytotoxicity to HCT15 and A459 selectively. PMID- 29189742 TI - Targeting Metastasis with Snake Toxins: Molecular Mechanisms. AB - Metastasis involves the migration of cancer cells from a primary tumor to invade and establish secondary tumors in distant organs, and it is the main cause for cancer-related deaths. Currently, the conventional cytostatic drugs target the proliferation of malignant cells, being ineffective in metastatic disease. This highlights the need to find new anti-metastatic drugs. Toxins isolated from snake venoms are a natural source of potentially useful molecular scaffolds to obtain agents with anti-migratory and anti-invasive effects in cancer cells. While there is greater evidence concerning the mechanisms of cell death induction of several snake toxin classes on cancer cells; only a reduced number of toxin classes have been reported on (i.e., disintegrins/disintegrin-like proteins, C-type lectin like proteins, C-type lectins, serinproteases, cardiotoxins, snake venom cystatins) as inhibitors of adhesion, migration, and invasion of cancer cells. Here, we discuss the anti-metastatic mechanisms of snake toxins, distinguishing three targets, which involve (1) inhibition of extracellular matrix components dependent adhesion and migration, (2) inhibition of epithelial-mesenchymal transition, and (3) inhibition of migration by alterations in the actin/cytoskeleton network. PMID- 29189743 TI - Site I Inactivation Impacts Calmodulin Calcium Binding and Activation of Bordetella pertussis Adenylate Cyclase Toxin. AB - Site I inactivation of calmodulin (CaM) was used to examine the importance of aspartic acid 22 at position 3 in CaM calcium binding, protein folding, and activation of the Bordetella pertussis adenylate cyclase toxin domain (CyaA-ACD). NMR calcium titration experiments showed that site I in the CaM mutant (D22A) remained largely unperturbed, while sites II, III, and IV exhibited calcium induced conformational changes similar to wild-type CaM (CaMWt). Circular dichroism analyses revealed that D22A had comparable alpha-helical content to CaMWt, and only modest differences in alpha-helical composition were detected between CaMWt-CyaA-ACD and D22A-CyaA-ACD complexes. However, the thermal stability of the D22A-CyaA-ACD complex was reduced, as compared to the CaMWt-CyaA ACD complex. Moreover, CaM-dependent activity of CyaA-ACD decreased 87% in the presence of D22A. Taken together, our findings provide evidence that D22A engages CyaA-ACD, likely through C-terminal mediated binding, and that site I inactivation exerts functional effects through the modification of stabilizing interactions that occur between N-terminal CaM and CyaA-ACD.

AB - In recent years there has been an increasing tendency to recycle the wastes generated by building companies in the construction industry, demolition wastes being the most important in terms of volume. The aim of this work is to study the possibility of using recycled aggregates from construction and demolition wastes in the preparation of precast non-structural concretes. To that purpose, two different percentages (15% and 30%) of natural aggregates were substituted by recycled aggregates in the manufacture of paving blocks and hollow tiles. Dosages used by the company have not been changed by the introduction of recycled aggregate. Precast elements have been tested by means of compressive and flexural strength, water absorption, density, abrasion, and slipping resistance. The results obtained show the possibility of using these wastes at an industrial scale, satisfying the requirements of the Spanish standards for these elements. PMID- 29189744 TI - Nanoparticle/Metal-Organic Framework Composites for Catalytic Applications: Current Status and Perspective. AB - Nanoparticle/metal-organic frameworks (MOF) based composites have recently attracted significant attention as a new class of catalysts. Such composites possess the unique features of MOFs (including clearly defined crystal structure, high surface area, single site catalyst, special confined nanopore, tunable, and uniform pore structure), but avoid some intrinsic weaknesses (like limited electrical conductivity and lack in the "conventional" catalytically active sites). This review summarizes the developed strategies for the fabrication of nanoparticle/MOF composites for catalyst uses, including the strategy using MOFs as host materials to hold and stabilize the guest nanoparticles, the strategy with subsequent MOF growth/assembly around pre-synthesized nanoparticles and the strategy mixing the precursors of NPs and MOFs together, followed by self assembly process or post-treatment or post-modification. The applications of nanoparticle/MOF composites for CO oxidation, CO2 conversion, hydrogen production, organic transformations, and degradation of pollutants have been discussed. Superior catalytic performances in these reactions have been demonstrated. Challenges and future developments are finally addressed.

AB - Microgreens are an excellent source of health-maintaining compounds, and the accumulation of these compounds in plant tissues may be stimulated by exogenous stimuli. While light quality effects on green basil microgreens are known, the present paper aims at improving the quality of acyanic (green) and cyanic (red) basil microgreens with different ratios of LED blue and red illumination. Growth, assimilatory and anthocyanin pigments, chlorophyll fluorescence, total phenolic, flavonoids, selected phenolic acid contents and antioxidant activity were assessed in microgreens grown for 17 days. Growth of microgreens was enhanced with predominantly blue illumination, larger cotyledon area and higher fresh mass. The same treatment elevated chlorophyll a and anthocyanin pigments contents. Colored light treatments decreased chlorophyll fluorescence PhiPSII values significantly in the green cultivar. Stimulation of phenolic synthesis and free radical scavenging activity were improved by predominantly red light in the green cultivar (up to 1.87 fold) and by predominantly blue light in the red cultivar (up to 1.73 fold). Rosmarinic and gallic acid synthesis was higher (up to 15- and 4-fold, respectively, compared to white treatment) in predominantly blue illumination. Red and blue LED ratios can be tailored to induce superior growth and phenolic contents in both red and green basil microgreens, as a convenient tool for producing higher quality foods. PMID- 29189747 TI - Neurological and Sleep Disturbances in Bronchiectasis. AB - Bronchiectasis unrelated to cystic fibrosis is a chronic lung disease that is increasingly recognised worldwide. While other common chronic lung conditions such as chronic obstructive lung disease have been associated with cardiovascular disease, there is a paucity of data on the relationship between bronchiectasis and cardiovascular risks such as stroke and sleep disturbance. Furthermore, it is unclear whether other neuropsychological aspects are affected, such as cognition, cerebral infection, anxiety and depression. In this review, we aim to highlight neurological and sleep issues in relation to bronchiectasis and their importance to patient care.

AB - Heat has been used extensively in the food industry as a preservation method, especially due to its ability to inactivate microorganisms present in foods. However, many aspects regarding the mechanisms of bacterial inactivation by heat and the factors affecting this process are still not fully understood. The purpose of this review is to offer a general overview of the most important aspects of the physiology of the inactivation or survival of microorganisms, particularly vegetative bacteria, submitted to heat treatments. This could help improve the design of current heat processes methods in order to apply milder and/or more effective treatments that could fulfill consumer requirements for fresh-like foods while maintaining the advantages of traditional heat treatments.

AB - The influence of climatic factors, e.g., low temperature, on the phytochemical composition and bioactivity of the arctic plant Dracocephalum palmatum Steph. ax Willd. (palmate dragonhead), a traditional food and medical herb of Northern Siberia, was investigated. D. palmatum seedlings were grown in a greenhouse experiment at normal (20 degrees C, NT) and low (1 degrees C, LT) temperature levels and five groups of components that were lipophilic and hydrophilic in nature were characterized. The analyses indicated that D. palmatum under NT demonstrates high content of photosynthetic pigments, specific fatty acid (FA) profile with domination of saturated FA (53.3%) and the essential oil with trans pinocamphone as a main component (37.9%). Phenolic compounds were identified using a combination of high performance liquid chromatography with diode array detection and electrospray ionization mass-spectrometric detection (HPLC-DAD-ESI MS) techniques, as well as free carbohydrates and water soluble polysaccharides. For the first time, it was established that the cold acclimation of D. palmatum seedlings resulted in various changes in physiological and biochemical parameters such as membrane permeability, photosynthetic potential, membrane fluidity, leaf surface secretory function, reactive oxygen species-antioxidant balance, osmoregulator content and cell wall polymers. In brief, results showed that the adaptive strategy of D. palmatum under LT was realized on the accumulation of membrane or surface components with more fluid properties (unsaturated FA and essential oils), antioxidants (phenolic compounds and enzymes), osmoprotectants (free sugars) and cell wall components (polysaccharides). In addition, the occurrence of unusual flavonoids including two new isomeric malonyl esters of eriodictyol-7-O-glucoside was found in LT samples. Data thus obtained allow improving our understanding of ecophysiological mechanisms of cold adaptation of arctic plants.

AB - As excess water is discharged from a high dam, low frequency noise (air pulsation lower than 10 Hz, LFN) is generated and propagated in the surrounding areas, causing environmental hazards such as the vibration of windows and doors and the discomfort of local residents. To study the generation mechanisms and key influencing factors of LFN induced by flood discharge and energy dissipation from a high dam with a ski-jump type spillway, detailed prototype observations and analyses of LFN are carried out. The discharge flow field is simulated and analyzed using a gas-liquid turbulent flow model. The acoustic response characteristics of the air cavity, which is formed between the discharge nappe and dam body, are analyzed using an acoustic numerical model. The multi-sources generation mechanisms are first proposed basing on the prototype observation results, vortex sound model, turbulent flow model and acoustic numerical model. Two kinds of sources of LFN are studied. One comes from the energy dissipation of submerged jets in the plunge pool, the other comes from nappe-cavity coupled vibration. The results of the analyses reveal that the submerged jets in the plunge pool only contribute to an on-site LFN energy of 0-1.0 Hz, and the strong shear layers around the high-velocity submerged jets and wall jet development areas are the main acoustic source regions of LFN in the plunge pool. In addition, the nappe-cavity coupled vibration, which is induced when the discharge nappe vibrates with close frequency to the model frequency of the cavity, can induce on-site LFN energy with wider frequency spectrum energy within 0-4.0 Hz. By contrast, the contribution degrees to LFN energy from two acoustic sources are almost same, while the contribution degree from nappe-cavity coupled vibration is slightly higher.

AB - Structural equation modeling was used to analyze partial and total in situ annoyance in combined transportation noise situations. A psychophysical total annoyance model and a perceptual total annoyance model were proposed. Results show a high contribution of Noise exposure and Noise sensitivity to Noise annoyance, as well as a causal relationship between noise annoyance and lower Dwelling satisfaction. Moreover, the Visibility of noise source may increase noise annoyance, even when the visible noise source is different from the annoying source under study. With regards to total annoyance due to road traffic noise combined with railway or aircraft noise, even though in both situations road traffic noise may be considered background noise and the other noise source event noise, the contribution of road traffic noise to the models is greater than railway noise and smaller than aircraft noise. This finding may be explained by the difference in sound pressure levels between these two types of combined exposures or by the aircraft noise level, which may also indicate the city in which the respondents live. Finally, the results highlight the importance of sample size and variable distribution in the database, as different results can be observed depending on the sample or variables considered. PMID- 29189752 TI - T-2 Toxin/HT-2 Toxin and Ochratoxin A ELISAs Development and In-House Validation in Food in Accordance with the Commission Regulation (EU) No 519/2014. AB - T-2 toxin/HT-2 toxin (T-2/HT-2) and ochratoxin A (OTA) are mycotoxins that can contaminate a variety of agricultural commodities. To protect consumers' health, indicative limits for T-2/HT-2 and maximum limits for OTA have been set by the European Commission, requiring food business operators and controlling agencies to conduct routine checks for the presence of these harmful contaminants. Screening methods are increasingly used for monitoring purposes. Due to the demand for new and improved screening tools, two individual detection methods, T 2/HT-2 and OTA enzyme-linked immunosorbent assays (ELISAs), were developed in this study. The T-2/HT-2 ELISA was based on a T-2 monoclonal antibody with an IC50 (50% inhibitory concentration) of 0.28 ng/mL and 125% cross-reactivity with HT-2. As regards the OTA ELISA, a new sensitive monoclonal antibody specific to OTA with an IC50 of 0.13 ng/mL was produced. Both developed ELISA tests were then validated in agricultural commodities in accordance with the new performance criteria guidelines for the validation of screening methods for mycotoxins included in Commission Regulation (EU) No 519/2014. The T-2/HT-2 ELISA was demonstrated to be suitable for the detection of T-2/HT-2 in cereals and baby food at and above the screening target concentration (STC) of 12.5 MUg/kg and 7.5 MUg/kg, respectively. The OTA ELISA was shown to be applicable for the detection of OTA in cereals, coffee, cocoa and wine at and above the STC of 2 MUg/kg, 2.5 MUg/kg, 2.5 MUg/kg and 0.4 ng/mL, respectively. The accuracy of both ELISAs was further confirmed by analysing proficiency test and reference samples. The developed methods can be used for sensitive and high-throughput screening for the presence of T-2/HT-2 and OTA in agricultural commodities. PMID- 29189753 TI - A Sensitive and Stable Surface Plasmon Resonance Sensor Based on Monolayer Protected Silver Film. AB - In this paper, we present a stable silver-based surface plasmon resonance (SPR) sensor using a self-assembled monolayer (SAM) as a protection layer and investigated its efficiency in water and 0.01 M phosphate buffered saline (PBS). By simulation, silver-based SPR sensor has a better performance in field enhancement and penetration depth than that of a gold-based SPR sensor, which are 5 and 1.4 times, respectively. To overcome the instability of the bare silver film and investigate the efficiency of the protected layer, the SAM of 11 mercapto-1-undecanol (MUD) was used as a protection layer. Stability experiment results show that the protected silver film exhibited excellent stability either in pure water or 0.01 M PBS buffer. The sensitivity of the silver-based SPR sensor was calculated to be 127.26 deg/RIU (refractive index unit), measured with different concentrations of NaCl solutions. Further, a very high refractive resolution for the silver-based SPR sensor was found to be 2.207 * 10-7 RIU, which reaches the theoretical limit in the wavelength of 632.8 nm for a SPR sensor reported in the literature. Using a mixed SAM of 16-mercaptohexadecanoic acid (MHDA) and a MUD layer with a ratio of 1:10, this immunosensor for the rabbit immunoglobulin G (IgG) molecule with a limit of detection as low as 22.516 ng/mL was achieved.

AB - In this work, the performance of five different fiber optic sensors at cryogenic temperatures has been analyzed. A photonic crystal fiber Fabry-Perot interferometer, two Sagnac interferometers, a commercial fiber Bragg grating (FBG), and a pi-phase shifted fiber Bragg grating interrogated in a random distributed feedback fiber laser have been studied. Their sensitivities and resolutions as sensors for cryogenic temperatures have been compared regarding their advantages and disadvantages. Additionally, the results have been compared with the given by a commercial optical backscatter reflectometer that allowed for distributed temperature measurements of a single mode fiber. PMID- 29189754 TI - Microbial Insight into a Pilot-Scale Enhanced Two-Stage High-Solid Anaerobic Digestion System Treating Waste Activated Sludge. AB - High solid anaerobic digestion (HSAD) is a rapidly developed anaerobic digestion technique for treating municipal sludge, and has been widely used in Europe and Asia. Recently, the enhanced HSAD process with thermal treatment showed its advantages in both methane production and VS reduction. However, the understanding of the microbial community is still poor. This study investigated microbial communities in a pilot enhanced two-stage HSAD system that degraded waste activated sludge at 9% solid content. The system employed process "thermal pre-treatment (TPT) at 70 degrees C, thermophilic anaerobic digestion (TAD), and mesophilic anaerobic digestion (MAD)". Hydrogenotrophic methanogens Methanothermobacter spp. dominated the system with relative abundance up to about 100% in both TAD and MAD. Syntrophic acetate oxidation (SAO) bacteria were discovered in TAD, and they converted acetate into H2 and CO2 to support hydrogenotrophic methanogenesis. The microbial composition and conversion route of this system are derived from the high solid content and protein content in raw sludge, as well as the operational conditions. This study could facilitate the understanding of the enhanced HSAD process, and is of academic and industrial importance. PMID- 29189756 TI - The Role of China in the UK Relative Imports from Three Selected Trading Regions: The Case of Textile Raw Material Industry. AB - The UK textile industry was very prosperous in the past but in the 1970s Britain started to import textile materials from abroad. Since 1990, half of its textile materials have been imported from the EEA (European Economic Area), ASEAN (Association of Southeast Asian Nations) and North America countries. Meanwhile, UK imports from China have increased dramatically. Through comparisons, this paper calculates the trade competitiveness index and relative competitive advantages of regions and investigates the impact of Chinese textiles on UK imports from three key free trade regions across the textile sectors in the period 1990-2016 on the basis of United Nation Comtrade Rev. 3. We find that China's textile prices, product techniques, political trade barriers and even tax system have made a varied impact on the UK's imports across related sectors in the context of green trade and the strengthening of barriers, which helps us recognize China's competitiveness in international trading and also provides advice on China's sustainable development of textile exports. PMID- 29189757 TI - A Denoising Method for Randomly Clustered Noise in ICCD Sensing Images Based on Hypergraph Cut and Down Sampling. AB - Intensified charge-coupled device (ICCD) images are captured by ICCD sensors in extremely low-light conditions. They often contains spatially clustered noises and general filtering methods do not work well. We find that the scale of the clustered noise in ICCD sensing images is often much smaller than that of the true structural information. Then the clustered noise can be identified by properly down-sampling and then up-sampling the ICCD sensing image and comparing it to the noisy image. Based on this finding, we present a denoising algorithm to remove the randomly clustered noise in ICCD images. First, we over-segment the ICCD image into a set of flat patches, and each patch contains very little structural information. Second, we classify the patches into noisy patches and noise-free patches based on the hypergraph cut method. Then the noise-free patches are easily recovered by the general block-matching and 3D filtering (BM3D) algorithm, since they often do not contain the clustered noise. The noisy patches are recovered by subtracting the identified clustered noise from the noisy patches. After that, we could get the whole recovered ICCD image. Finally, the quality of the recovered ICCD image is further improved by diminishing the remaining sparse noise with robust principal component analysis. Experiments are conducted on a set of ICCD images and compared with four existing denoising algorithms, which shows that the proposed algorithm removes well the randomly clustered noise and preserves the true textural information in the ICCD sensing images. PMID- 29189758 TI - Modeling of Sensor Placement Strategy for Shape Sensing and Structural Health Monitoring of a Wing-Shaped Sandwich Panel Using Inverse Finite Element Method. AB - This paper investigated the effect of sensor density and alignment for three dimensional shape sensing of an airplane-wing-shaped thick panel subjected to three different loading conditions, i.e., bending, torsion, and membrane loads. For shape sensing analysis of the panel, the Inverse Finite Element Method (iFEM) was used together with the Refined Zigzag Theory (RZT), in order to enable accurate predictions for transverse deflection and through-the-thickness variation of interfacial displacements. In this study, the iFEM-RZT algorithm is implemented by utilizing a novel three-node C degrees -continuous inverse-shell element, known as i3-RZT. The discrete strain data is generated numerically through performing a high-fidelity finite element analysis on the wing-shaped panel. This numerical strain data represents experimental strain readings obtained from surface patched strain gauges or embedded fiber Bragg grating (FBG) sensors. Three different sensor placement configurations with varying density and alignment of strain data were examined and their corresponding displacement contours were compared with those of reference solutions. The results indicate that a sparse distribution of FBG sensors (uniaxial strain measurements), aligned in only the longitudinal direction, is sufficient for predicting accurate full field membrane and bending responses (deformed shapes) of the panel, including a true zigzag representation of interfacial displacements. On the other hand, a sparse deployment of strain rosettes (triaxial strain measurements) is essentially enough to produce torsion shapes that are as accurate as those of predicted by a dense sensor placement configuration. Hence, the potential applicability and practical aspects of i3-RZT/iFEM methodology is proven for three-dimensional shape-sensing of future aerospace structures. PMID- 29189759 TI - Study of SH-SY5Y Cancer Cell Response to Treatment with Polyphenol Extracts Using FT-IR Spectroscopy. AB - Plant polyphenols are important components of human diet and a number of them are considered to possess chemo-preventive and therapeutic properties against cancer. They are recognized as naturally occurring antioxidants, but also as pro-oxidant, pro-apoptotic, or chromosomal aberrations inducers, depending on their concentration and/or the stage of cell-cycle of the cells with which they interact. For these reasons, particular interest is devoted to knowing the total effects of polyphenols on the cell cycle and metabolism. Fourier-Transform Infrared (FT-IR) spectroscopy thanks to its ability in analyzing cells at a molecular level can be particularly useful in investigating the biochemical changes induced in protein, nucleic acid, lipid, and carbohydrate content of cells by means of polyphenols administration. Spectroscopic analysis was performed on in vitro human SH-SY5Y neuroblastoma cells that were exposed to different doses of a cherry derived polyphenol extract. The infrared spectra that were obtained from unexposed and exposed cells show significant differences that can be helpful in order to understand the cells-polyphenols interaction. PMID- 29189760 TI - Electrochemical Immunosensor for the Detection of Aflatoxin B1 in Palm Kernel Cake and Feed Samples. AB - Palm kernel cake (PKC) is the solid residue following oil extraction of palm kernels and useful to fatten animals either as a single feed with only minerals and vitamins supplementation, or mixed with other feedstuffs such as corn kernels or soy beans. The occurrence of mycotoxins (aflatoxins, ochratoxins, zearalenone, and fumonisins) in feed samples affects the animal's health and also serves as a secondary contamination to humans via consumption of eggs, milk and meats. Of these, aflatoxin B1 (AFB1) is the most toxically potent and a confirmed carcinogen to both humans and animals. Methods such as High Performance Liquid Chromatography (HPLC) and Liquid Chromatography-Mass Spectrometry (LC-MS/MS) are common in the determination of mycotoxins. However, these methods usually require sample pre-treatment, extensive cleanup and skilled operator. Therefore, in the present work, a rapid method of electrochemical immunosensor for the detection of AFB1 was developed based on an indirect competitive enzyme-linked immunosorbent assay (ELISA). Multi-walled carbon nanotubes (MWCNT) and chitosan (CS) were used as the electrode modifier for signal enhancement. N-ethyl-N'-(3 dimethylaminopropyl)-carbodiimide (EDC) and N-hydroxysuccinimide (NHS) activated the carboxyl groups at the surface of nanocomposite for the attachment of AFB1 BSA antigen by covalent bonding. An indirect competitive reaction occurred between AFB1-BSA and free AFB1 for the binding site of a fixed amount of anti AFB1 antibody. A catalytic signal based on horseradish peroxidase (HRP) in the presence of hydrogen peroxide (H2O2) and 3,3',5,5'-tetramethylbenzidine (TMB) mediator was observed as a result of attachment of the secondary antibody to the immunoassay system. As a result, the reduction peak of TMB(Ox) was measured by using differential pulse voltammetry (DPV) analysis. Based on the results, the electrochemical surface area was increased from 0.396 cm2 to 1.298 cm2 due to the electrode modification with MWCNT/CS. At the optimal conditions, the working range of the electrochemical immunosensor was from 0.0001 to 10 ng/mL with limit of detection of 0.1 pg/mL. Good recoveries were obtained for the detection of spiked feed samples (PKC, corn kernels, soy beans). The developed method could be used for the screening of AFB1 in real samples. PMID- 29189761 TI - Heterogenization of Ketone Catalyst for Epoxidation by Low Pressure Plasma Fluorination of Silica Gel Supports. AB - Low pressure plasma was used for preparing heterogeneous organocatalysts 2-(A) (C) suitable for dioxirane-mediated epoxidations. Heterogenization was accomplished by adsorption of the methyl perfluoroheptyl ketone (2) on fluorinated supports (A)-(C) deriving from the treatment of commercial C8-silica gel in low pressure plasma fed with fluorocarbons. Catalyst 2-(C) proved to be the most efficient one, promoting epoxidation of an array of alkenes, including unsaturated fatty esters like methyl oleate (10) and the triglyceride soybean oil (11), with the cheap potassium peroxymonosulfate KHSO5 (caroate) as a green oxidant. Notably, the perfluorinated matrix gives rise to the activation of caroate, generating singlet oxygen. Materials were characterized by infrared Attenuated Total Reflectance spectroscopy (ATR-FTIR), X-ray Photoelectron Spectroscopy (XPS ) and Emission Scanning Electron Microscope (FESEM). PMID- 29189763 TI - Formation and Stability of Prebiotically Relevant Vesicular Systems in Terrestrial Geothermal Environments. AB - Terrestrial geothermal fields and oceanic hydrothermal vents are considered as candidate environments for the emergence of life on Earth. Nevertheless, the ionic strength and salinity of oceans present serious limitations for the self assembly of amphiphiles, a process that is fundamental for the formation of first protocells. Consequently, we systematically characterized the efficiency of amphiphile assembly, and vesicular stability, in terrestrial geothermal environments, both, under simulated laboratory conditions and in hot spring water samples (collected from Ladakh, India, an Astrobiologically relevant site). Combinations of prebiotically pertinent fatty acids and their derivatives were evaluated for the formation of vesicles in aforesaid scenarios. Additionally, the stability of these vesicles was characterized over multiple dehydration rehydration cycles, at elevated temperatures. Among the combinations that were tested, mixtures of fatty acid and its glycerol derivatives were found to be the most robust, also resulting in vesicles in all of the hot spring waters that were tested. Importantly, these vesicles were stable at high temperatures, and this fatty acid system retained its vesicle forming propensity, even after multiple cycles of dehydration-rehydration. The remaining systems, however, formed vesicles only in bicine buffer. Our results suggest that certain prebiotic compartments would have had a selective advantage in terrestrial geothermal niches. Significantly, our study highlights the importance of validating results that are obtained under 'buffered' laboratory conditions, by verifying their plausibility in prebiotically analogous environments. PMID- 29189762 TI - Synthesis and In Vitro Antimycobacterial Activity of Novel N-Arylpiperazines Containing an Ethane-1,2-diyl Connecting Chain. AB - Novel 1-(2-{3-/4-[(alkoxycarbonyl)amino]phenyl}-2-hydroxyethyl)-4-(2 fluorophenyl)-piperazin-1-ium chlorides (alkoxy = methoxy to butoxy; 8a-h) have been designed and synthesized through multistep reactions as a part of on-going research programme focused on finding new antimycobacterials. Lipophilic properties of these compounds were estimated by RP-HPLC using methanol/water mobile phases with a various volume fraction of the organic modifier. The log kw values, which were extrapolated from intercepts of a linear relationship between the logarithm of a retention factor k (log k) and volume fraction of a mobile phase modifier (phiM), varied from 2.113 (compound 8e) to 2.930 (compound 8h) and indicated relatively high lipophilicity of these salts. Electronic properties of the molecules 8a-h were investigated by evaluation of their UV/Vis spectra. In a next phase of the research, the compounds 8a-h were in vitro screened against M. tuberculosis CNCTC My 331/88 (identical with H37Rv and ATCC 2794), M. kansasii CNCTC My 235/80 (identical with ATCC 12478), a M. kansasii 6 509/96 clinical isolate, M. avium CNCTC My 330/80 (identical with ATCC 25291) and M. avium intracellulare ATCC 13950, respectively, as well as against M. kansasii CIT11/06, M. avium subsp. paratuberculosis CIT03 and M. avium hominissuis CIT10/08 clinical isolates using isoniazid, ethambutol, ofloxacin, ciprofloxacin or pyrazinamide as reference drugs. The tested compounds 8a-h were found to be the most promising against M. tuberculosis; a MIC = 8 MUM was observed for the most effective 1-(2 {4-[(butoxycarbonyl)amino]phen-ylphenyl}-2-hydroxyethyl)-4-(2 fluorophenyl)piperazin-1-ium chloride (8h). In addition, all of them showed low (insignificant) in vitro toxicity against a human monocytic leukemia THP-1 cell line, as observed LD50 values > 30 MUM indicated. The structure-antimycobacterial activity relationships of the analyzed 8a-h series are also discussed. PMID- 29189764 TI - A Comprehensive Approach to Motorcycle-Related Head Injury Prevention: Experiences from the Field in Vietnam, Cambodia, and Uganda. AB - Motorcyclists account for 23% of global road traffic deaths and over half of fatalities in countries where motorcycles are the dominant means of transport. Wearing a helmet can reduce the risk of head injury by as much as 69% and death by 42%; however, both child and adult helmet use are low in many countries where motorcycles are a primary mode of transportation. In response to the need to increase helmet use by all drivers and their passengers, the Global Helmet Vaccine Initiative (GHVI) was established to increase helmet use in three countries where a substantial portion of road users are motorcyclists and where helmet use is low. The GHVI approach includes five strategies to increase helmet use: targeted programs, helmet access, public awareness, institutional policies, and monitoring and evaluation. The application of GHVI to Vietnam, Cambodia, and Uganda resulted in four key lessons learned. First, motorcyclists are more likely to wear helmets when helmet use is mandated and enforced. Second, programs targeted to at-risk motorcyclists, such as child passengers, combined with improved awareness among the broader population, can result in greater public support needed to encourage action by decision-makers. Third, for broad population-level change, using multiple strategies in tandem can be more effective than using a single strategy alone. Lastly, the successful expansion of GHVI into Cambodia and Uganda has been hindered by the lack of helmet accessibility and affordability, a core component contributing to its success in Vietnam. This paper will review the development of the GHVI five-pillar approach in Vietnam, subsequent efforts to implement the model in Cambodia and Uganda, and lessons learned from these applications to protect motorcycle drivers and their adult and child passengers from injury. PMID- 29189765 TI - Phylogenetic Analysis of the SNORD116 Locus. AB - The SNORD116 small nucleolar RNA locus (SNORD116@) is contained within the long noncoding RNA host gene SNHG14 on human chromosome 15q11-q13. The SNORD116 locus is a cluster of 28 or more small nucleolar (sno) RNAs; C/D box (SNORDs). Individual RNAs within the cluster are tandem, highly similar sequences, referred to as SNORD116-1, SNORD116-2, etc., with the entire set referred to as SNORD116@. There are also related SNORD116 loci on other chromosomes, and these additional loci are conserved among primates. Inherited chromosomal 15q11-q13 deletions, encompassing the SNORD116@ locus, are causative for the paternally inherited/maternally-imprinted genetic condition, Prader-Willi syndrome (PWS). Using in silico tools, along with molecular-based and sequenced-based confirmation, phylogenetic analysis of the SNORD116@ locus was performed. The consensus sequence for the SNORD116@ snoRNAs from various species was determined both for all the SNORD116 snoRNAs, as well as those grouped using sequence and location according to a human grouping convention. The implications of these findings are put in perspective for studying SNORD116 in patients with inherited Prader-Willi syndrome, as well as model organisms. PMID- 29189766 TI - Health Challenges in Refugee Reception: Dateline Europe 2016. AB - The arrival of more than one million migrants, many of them refugees, has proved a major test for the European Union. Although international relief and monitoring agencies have been critical of makeshift camps in Calais and Eidomeni where infectious disease and overcrowding present major health risks, few have examined the nature of the official reception system and its impact on health delivery. Drawing upon research findings from an Economic and Social Research Council (ESRC) funded project, this article considers the physical and mental health of asylum-seekers in transit and analyses how the closure of borders has engendered health risks for populations in recognised reception centres in Sicily and in Greece. Data gathered by means of a survey administered in Greece (300) and in Sicily (400), and complemented by in-depth interviews with migrants (45) and key informants (50) including representatives of government offices, humanitarian and relief agencies, NGOs and activist organisations, are presented to offer an analysis of the reception systems in the two frontline states. We note that medical provision varies significantly from one centre to another and that centre managers play a critical role in the transmission of vital information. A key finding is that, given such disparity, the criteria used by the UNHCR to grade health services reception do not address the substantive issue that prevent refugees from accessing health services, even when provided on site. Health provision is not as recorded in UNHCR reporting but rather there are critical gaps between provision, awareness, and access for refugees in reception systems in Sicily and in Greece. This article concludes that there is a great need for more information campaigns to direct refugees to essential services. PMID- 29189767 TI - Blood-Based Protein Signatures for Early Detection of Colorectal Cancer: A Systematic Review. AB - OBJECTIVES: Blood-based proteins might be an attractive option for early detection of colorectal cancer (CRC), but individually they are unlikely to achieve the diagnostic performance required for population based screening. We aimed at summarizing current evidence of diagnostic performance of signatures based on multiple proteins for early detection of CRC. METHODS: A systematic literature review adhering to the PRISMA (preferred reporting items for systematic reviews and meta-analysis) guidelines was performed. PubMed and Web of Science databases were searched for potentially relevant studies published until 28th August, 2017. Relevant studies were identified by predefined eligibility criteria. Estimates of indicators of diagnostic performance such as sensitivity, specificity, and the area under the curve (AUC), along with information on validation and other key methodological procedures were extracted. Study quality was assessed by a QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies 2) instrument tool. RESULTS: Thirty six eligible studies with numbers of CRC cases ranging from 23 to 512 and the number of proteins included in signatures ranged from 3 to 13 were identified. Reported Youden's Index and AUC ranged from 0.19 to 0.95 and from 0.62 to 0.996, respectively. However most studies, especially those reporting better diagnostic performance, were conducted in clinical rather than screening setting and many studies lacked any internal or external validation of identified algorithm. CONCLUSIONS: Blood-based tests using signatures of multiple proteins may be a promising approach for non-invasive CRC screening. However, promising signatures identified in clinical settings still require rigorous evaluation in large studies conducted in true screening setting. PMID- 29189768 TI - Inflammatory Bowel Disease Adversely Impacts Colorectal Cancer Surgery Short-term Outcomes and Health-Care Resource Utilization. AB - OBJECTIVES: Inflammatory bowel disease (IBD) is associated with an increased risk of colorectal cancer (CRC) compared to patients without IBD. There is a lack of population-based data evaluating the in-patient surgical outcomes of CRC in IBD patients. We sought to compare the hospital outcomes of CRC surgery between patients with and without IBD. METHODS: We used the National Inpatient Sample (2008-2012) and Nationwide Readmissions Database (NRD, 2013) and selected all adult patients (age >=18 years) with ulcerative colitis (UC) or Crohn's disease (CD) who underwent CRC surgery. Multivariate analysis for in-patient outcomes of postoperative complications, health-care resource utilization, readmission rate, and mortality were performed. RESULTS: A total of 397,847 patients underwent CRC surgery from 2008 to 2012, of which 0.8% (3,242) had IBD. Compared to CRC in non IBD patients, CRC in IBD patients had longer length of stay (adjusted coefficient (AC) 0.86 days, 95% confidence interval (CI): 0.42, 1.30), more likely developed postoperative complications (adjusted odds ratio (AOR) 1.26, 95% CI: 1.06, 1.50), including postoperative infection (AOR 1.69, 95% CI: 1.20, 2.38) and deep vein thrombosis (AOR 2.42, 95% CI: 1.36, 4.28), and more frequently required blood transfusion (AOR 1.59, 95% CI: 1.30, 1.94). CRC in IBD patients was more likely to be readmitted within 30 days (AOR 1.44, 95% CI: 1.01, 2.04). CONCLUSION: At a population level, IBD adversely impacts outcomes at the time of CRC surgery. PMID- 29189769 TI - Preparation of viable adult ventricular myocardial slices from large and small mammals. AB - This protocol describes the preparation of highly viable adult ventricular myocardial slices from the hearts of small and large mammals, including rodents, pigs, dogs and humans. Adult ventricular myocardial slices are 100- to 400-MUm thick slices of living myocardium that retain the native multicellularity, architecture and physiology of the heart. This protocol provides a list of the equipment and reagents required alongside a detailed description of the methodology for heart explantation, tissue preparation, slicing with a vibratome and handling of myocardial slices. Supplementary videos are included to visually demonstrate these steps. A number of critical steps are addressed that must be followed in order to prepare highly viable myocardial slices. These include identification of myocardial fiber direction and fiber alignment within the tissue block, careful temperature control, use of an excitation-contraction uncoupler, optimal vibratome settings and correct handling of myocardial slices. Many aspects of cardiac structure and function can be studied using myocardial slices in vitro. Typical results obtained with hearts from a small mammal (rat) and a large mammal (human) with heart failure are shown, demonstrating myocardial slice viability, maximum contractility, Ca2+ handling and structure. This protocol can be completed in ~4 h. PMID- 29189770 TI - Langmuir-Blodgett nanotemplates for protein crystallography. AB - The new generation of synchrotrons and microfocused beamlines has enabled great progress in X-ray protein crystallography, resulting in new 3D atomic structures for proteins of high interest to the pharmaceutical industry and life sciences. It is, however, often still challenging to produce protein crystals of sufficient size and quality (order, intensity of diffraction, radiation stability). In this protocol, we provide instructions for performing the Langmuir-Blodgett (LB) nanotemplate method, a crystallization approach that can be used for any protein (including membrane proteins). We describe how to produce highly ordered 2D LB protein monolayers at the air-water interface and deposit them on glass slides. LB-film formation can be observed by surface-pressure measurements and Brewster angle microscopy (BAM), although its quality can be characterized by atomic force microscopy (AFM) and nanogravimetry. Such films are then used as a 2D template for triggering 3D protein crystal formation by hanging-drop vapor diffusion. The procedure for forming the 2D template takes a few minutes. Structural information about the protein reorganization in the LB film during the crystallization process on the nano level can be obtained using an in situ submicron GISAXS (grazing-incidence small-angle X-ray scattering) method. MicroGISAXS spectra, measured directly at the interface of the LB films and protein solution in real time, as described in this protocol, can be interpreted in terms of the buildup of layers, islands, or holes. In our experience, the obtained LB crystals take 1 10 d to prepare and they are more ordered and radiation stable as compared with those produced using other crystallization methods. PMID- 29189771 TI - Chemical synthesis of membrane proteins by the removable backbone modification method. AB - Chemical synthesis can produce membrane proteins bearing specifically designed modifications (e.g., phosphorylation, isotope labeling) that are difficult to obtain through recombinant protein expression approaches. The resulting homogeneously modified synthetic membrane proteins are valuable tools for many advanced biochemical and biophysical studies. This protocol describes the chemical synthesis of membrane proteins by condensation of transmembrane peptide segments through native chemical ligation. To avoid common problems encountered due to the poor solubility of transmembrane peptides in almost any solvent, we describe an effective procedure for the chemical synthesis of membrane proteins through the removable-backbone modification (RBM) strategy. Two key steps of this protocol are: (i) installation of solubilizing Arg4-tagged RBM groups into the transmembrane peptides at any primary amino acid through Fmoc (9 fluorenylmethyloxycarbonyl) solid-phase peptide synthesis and (ii) native ligation of the full-length sequence, followed by removal of the RBM tags by TFA (trifluoroacetic acid) cocktails to afford the native protein. The installation of RBM groups is achieved by using 4-methoxy-5-nitrosalicyladehyde by reduction amination to incorporate an activated O-to-N acyl transfer auxiliary. The Arg4 tag-modified membrane-spanning peptide segments behave like water-soluble peptides to facilitate their purification, ligation and mass characterization. PMID- 29189772 TI - Production of knock-in mice in a single generation from embryonic stem cells. AB - The system-level identification and analysis of molecular networks in mammals can be accelerated by 'next-generation' genetics, defined as genetics that does not require crossing of multiple generations of animals in order to achieve the desired genetic makeup. We have established a highly efficient procedure for producing knock-in (KI) mice within a single generation, by optimizing the genome editing protocol for KI embryonic stem (ES) cells and the protocol for the generation of fully ES-cell-derived mice (ES mice). Using this protocol, the production of chimeric mice is eliminated, and, therefore, there is no requirement for the crossing of chimeric mice to produce mice that carry the KI gene in all cells of the body. Our procedure thus shortens the time required to produce KI ES mice from about a year to ~3 months. Various kinds of KI ES mice can be produced with a minimized amount of work, facilitating the elucidation of organism-level phenomena using a systems biology approach. In this report, we describe the basic technologies and protocols for this procedure, and discuss the current challenges for next-generation mammalian genetics in organism-level systems biology studies. PMID- 29189773 TI - Multimodal profiling of single-cell morphology, electrophysiology, and gene expression using Patch-seq. AB - Neurons exhibit a rich diversity of morphological phenotypes, electrophysiological properties, and gene-expression patterns. Understanding how these different characteristics are interrelated at the single-cell level has been difficult because of the lack of techniques for multimodal profiling of individual cells. We recently developed Patch-seq, a technique that combines whole-cell patch-clamp recording, immunohistochemistry, and single-cell RNA sequencing (scRNA-seq) to comprehensively profile single neurons from mouse brain slices. Here, we present a detailed step-by-step protocol, including modifications to the patching mechanics and recording procedure, reagents and recipes, procedures for immunohistochemistry, and other tips to assist researchers in obtaining high-quality morphological, electrophysiological, and transcriptomic data from single neurons. Successful implementation of Patch-seq allows researchers to explore the multidimensional phenotypic variability among neurons and to correlate gene expression with phenotype at the level of single cells. The entire procedure can be completed in ~2 weeks through the combined efforts of a skilled electrophysiologist, molecular biologist, and biostatistician. PMID- 29189774 TI - Deriving genotypes from RAD-seq short-read data using Stacks. AB - Restriction site-associated DNA sequencing (RAD-seq) allows for the genome-wide discovery and genotyping of single-nucleotide polymorphisms in hundreds of individuals at a time in model and nonmodel species alike. However, converting short-read sequencing data into reliable genotype data remains a nontrivial task, especially as RAD-seq is used in systems that have very diverse genomic properties. Here, we present a protocol to analyze RAD-seq data using the Stacks pipeline. This protocol will be of use in areas such as ecology and population genetics. It covers the assessment and demultiplexing of the sequencing data, read mapping, inference of RAD loci, genotype calling, and filtering of the output data, as well as providing two simple examples of downstream biological analyses. We place special emphasis on checking the soundness of the procedure and choosing the main parameters, given the properties of the data. The procedure can be completed in 1 week, but determining definitive methodological choices will typically take up to 1 month. PMID- 29189776 TI - Mild oxidation of methane to methanol or acetic acid on supported isolated rhodium catalysts. AB - An efficient and direct method of catalytic conversion of methane to liquid methanol and other oxygenates would be of considerable practical value. However, it remains an unsolved problem in catalysis, as typically it involves expensive or corrosive oxidants or reaction media that are not amenable to commercialization. Although methane can be directly converted to methanol using molecular oxygen under mild conditions in the gas phase, the process is either stoichiometric (and therefore requires a water extraction step) or is too slow and low-yielding to be practical. Methane could, in principle, also be transformed through direct oxidative carbonylation to acetic acid, which is commercially obtained through methane steam reforming, methanol synthesis, and subsequent methanol carbonylation on homogeneous catalysts. However, an effective catalyst for the direct carbonylation of methane to acetic acid, which might enable the economical small-scale utilization of natural gas that is currently flared or stranded, has not yet been reported. Here we show that mononuclear rhodium species, anchored on a zeolite or titanium dioxide support suspended in aqueous solution, catalyse the direct conversion of methane to methanol and acetic acid, using oxygen and carbon monoxide under mild conditions. We find that the two products form through independent pathways, which allows us to tune the conversion: three-hour-long batch-reactor tests conducted at 150 degrees Celsius, using either the zeolite-supported or the titanium-dioxide-supported catalyst, yield around 22,000 micromoles of acetic acid per gram of catalyst, or around 230 micromoles of methanol per gram of catalyst, respectively, with selectivities of 60-100 per cent. We anticipate that these unusually high activities, despite still being too low for commercial application, may guide the development of optimized catalysts and practical processes for the direct conversion of methane to methanol, acetic acid and other useful chemicals. PMID- 29189777 TI - Halogens in chondritic meteorites and terrestrial accretion. AB - Volatile element delivery and retention played a fundamental part in Earth's formation and subsequent chemical differentiation. The heavy halogens-chlorine (Cl), bromine (Br) and iodine (I)-are key tracers of accretionary processes owing to their high volatility and incompatibility, but have low abundances in most geological and planetary materials. However, noble gas proxy isotopes produced during neutron irradiation provide a high-sensitivity tool for the determination of heavy halogen abundances. Using such isotopes, here we show that Cl, Br and I abundances in carbonaceous, enstatite, Rumuruti and primitive ordinary chondrites are about 6 times, 9 times and 15-37 times lower, respectively, than previously reported and usually accepted estimates. This is independent of the oxidation state or petrological type of the chondrites. The ratios Br/Cl and I/Cl in all studied chondrites show a limited range, indistinguishable from bulk silicate Earth estimates. Our results demonstrate that the halogen depletion of bulk silicate Earth relative to primitive meteorites is consistent with the depletion of lithophile elements of similar volatility. These results for carbonaceous chondrites reveal that late accretion, constrained to a maximum of 0.5 +/- 0.2 per cent of Earth's silicate mass, cannot solely account for present-day terrestrial halogen inventories. It is estimated that 80-90 per cent of heavy halogens are concentrated in Earth's surface reservoirs and have not undergone the extreme early loss observed in atmosphere-forming elements. Therefore, in addition to late-stage terrestrial accretion of halogens and mantle degassing, which has removed less than half of Earth's dissolved mantle gases, the efficient extraction of halogen-rich fluids from the solid Earth during the earliest stages of terrestrial differentiation is also required to explain the presence of these heavy halogens at the surface. The hydropilic nature of halogens, whereby they track with water, supports this requirement, and is consistent with volatile-rich or water-rich late-stage terrestrial accretion. PMID- 29189775 TI - Visualizing endocytic recycling and trafficking in live neurons by subdiffractional tracking of internalized molecules. AB - Our understanding of endocytic pathway dynamics is restricted by the diffraction limit of light microscopy. Although super-resolution techniques can overcome this issue, highly crowded cellular environments, such as nerve terminals, can also dramatically limit the tracking of multiple endocytic vesicles such as synaptic vesicles (SVs), which in turn restricts the analytical dissection of their discrete diffusional and transport states. We recently introduced a pulse-chase technique for subdiffractional tracking of internalized molecules (sdTIM) that allows the visualization of fluorescently tagged molecules trapped in individual signaling endosomes and SVs in presynapses or axons with 30- to 50-nm localization precision. We originally developed this approach for tracking single molecules of botulinum neurotoxin type A, which undergoes activity-dependent internalization and retrograde transport in autophagosomes. This method was then adapted to localize the signaling endosomes containing cholera toxin subunit-B that undergo retrograde transport in axons and to track SVs in the crowded environment of hippocampal presynapses. We describe (i) the construction of a custom-made microfluidic device that enables control over neuronal orientation; (ii) the 3D printing of a perfusion system for sdTIM experiments performed on glass-bottom dishes; (iii) the dissection, culturing and transfection of hippocampal neurons in microfluidic devices; and (iv) guidance on how to perform the pulse-chase experiments and data analysis. In addition, we describe the use of single-molecule-tracking analytical tools to reveal the average and the heterogeneous single-molecule mobility behaviors. We also discuss alternative reagents and equipment that can, in principle, be used for sdTIM experiments and describe how to adapt sdTIM to image nanocluster formation and/or tubulation in early endosomes during sorting events. The procedures described in this protocol take ~1 week. PMID- 29189778 TI - Probing many-body dynamics on a 51-atom quantum simulator. AB - Controllable, coherent many-body systems can provide insights into the fundamental properties of quantum matter, enable the realization of new quantum phases and could ultimately lead to computational systems that outperform existing computers based on classical approaches. Here we demonstrate a method for creating controlled many-body quantum matter that combines deterministically prepared, reconfigurable arrays of individually trapped cold atoms with strong, coherent interactions enabled by excitation to Rydberg states. We realize a programmable Ising-type quantum spin model with tunable interactions and system sizes of up to 51 qubits. Within this model, we observe phase transitions into spatially ordered states that break various discrete symmetries, verify the high fidelity preparation of these states and investigate the dynamics across the phase transition in large arrays of atoms. In particular, we observe robust many body dynamics corresponding to persistent oscillations of the order after a rapid quantum quench that results from a sudden transition across the phase boundary. Our method provides a way of exploring many-body phenomena on a programmable quantum simulator and could enable realizations of new quantum algorithms.

PMID- 29189781 TI - Observation of a many-body dynamical phase transition with a 53-qubit quantum simulator. AB - A quantum simulator is a type of quantum computer that controls the interactions between quantum bits (or qubits) in a way that can be mapped to certain quantum many-body problems. As it becomes possible to exert more control over larger numbers of qubits, such simulators will be able to tackle a wider range of problems, such as materials design and molecular modelling, with the ultimate limit being a universal quantum computer that can solve general classes of hard problems. Here we use a quantum simulator composed of up to 53 qubits to study non-equilibrium dynamics in the transverse-field Ising model with long-range interactions. We observe a dynamical phase transition after a sudden change of the Hamiltonian, in a regime in which conventional statistical mechanics does not apply. The qubits are represented by the spins of trapped ions, which can be prepared in various initial pure states. We apply a global long-range Ising interaction with controllable strength and range, and measure each individual qubit with an efficiency of nearly 99 per cent. Such high efficiency means that arbitrary many-body correlations between qubits can be measured in a single shot, enabling the dynamical phase transition to be probed directly and revealing computationally intractable features that rely on the long-range interactions and high connectivity between qubits. PMID- 29189783 TI - Put safety first. PMID- 29189780 TI - A semi-synthetic organism that stores and retrieves increased genetic information. AB - Since at least the last common ancestor of all life on Earth, genetic information has been stored in a four-letter alphabet that is propagated and retrieved by the formation of two base pairs. The central goal of synthetic biology is to create new life forms and functions, and the most general route to this goal is the creation of semi-synthetic organisms whose DNA harbours two additional letters that form a third, unnatural base pair. Previous efforts to generate such semi synthetic organisms culminated in the creation of a strain of Escherichia coli that, by virtue of a nucleoside triphosphate transporter from Phaeodactylum tricornutum, imports the requisite unnatural triphosphates from its medium and then uses them to replicate a plasmid containing the unnatural base pair dNaM dTPT3. Although the semi-synthetic organism stores increased information when compared to natural organisms, retrieval of the information requires in vivo transcription of the unnatural base pair into mRNA and tRNA, aminoacylation of the tRNA with a non-canonical amino acid, and efficient participation of the unnatural base pair in decoding at the ribosome. Here we report the in vivo transcription of DNA containing dNaM and dTPT3 into mRNAs with two different unnatural codons and tRNAs with cognate unnatural anticodons, and their efficient decoding at the ribosome to direct the site-specific incorporation of natural or non-canonical amino acids into superfolder green fluorescent protein. The results demonstrate that interactions other than hydrogen bonding can contribute to every step of information storage and retrieval. The resulting semi-synthetic organism both encodes and retrieves increased information and should serve as a platform for the creation of new life forms and functions.

Moreover, in everyday life, we feel joy, fear, anger, and other emotions that influence our decisions in a little, "calculated" way. Not everyone, however, is also aware that the mistakes we make are often systematic and therefore, in particular circumstances, are foreseeable. Doctors and patients are constantly called upon to make decisions. They need to identify relevant information (for example, the symptoms or outcome of an examination), formulate a judgment (for example a diagnosis), choose an action course among the various possible ones based on one's own preferences (e.g. medication or surgery), so act. The exact size of the medical error is unknown, but probably huge. In fact, the more we investigate and the more we find. Often these mistakes depend on the cognitive process. Any (rational) decision requires, in particular, an assessment of the possible effects of the action it implements; for example how much pleasure or pain it will cause us. In the medical field, too, the principle of informed consent provides that the patient's preferences and values are to guide clinical choices. Yet, not always the preferences that people express before making an experience match with their preferences after living that experience. Some ingenious experiments suggest (in a seemingly paradoxical way) that before a direct experience, people prefer less pain; after that experience they prefer more, but with a better memory.

PMID- 29189820 TI - Somatic TP53 variants frequently confound germ-line testing results. AB - PURPOSE: Blood/saliva DNA is thought to represent the germ line in genetic cancer risk assessment. Cases with pathogenic TP53 variants detected by multigene panel testing are often discordant with Li-Fraumeni syndrome, raising concern about misinterpretation of acquired aberrant clonal expansions (ACEs) with TP53 variants as germ-line results. METHODS: Pathogenic TP53 variants with abnormal next-generation sequencing metrics (e.g., decreased ratio (<25%) of mutant to wild-type allele, more than two detected alleles) were selected from a CLIA laboratory testing cohort. Alternate tissues and/or close relatives were tested to distinguish between ACE and germ-line status. Clinical data and Li-Fraumeni syndrome testing criteria were examined. RESULTS: Among 114,630 multigene panel tests and 1,454 TP53 gene-specific analyses, abnormal next-generation sequencing metrics were observed in 20% of 353 TP53-positive results, and ACE was confirmed for 91% of cases with ancillary materials, most of these due to clonal hematopoiesis. Only four met Chompret criteria. Individuals with ACE were older (50 years vs. 33.7; P = 0.02) and were identified more frequently in multigene panel tests (66/285; 23.2%) than in TP53 gene-specific tests (6/68; 8.8%, P = 0.005). CONCLUSION: ACE confounds germ-line diagnosis, may portend hematologic malignancy, and may provoke unwarranted clinical interventions. Ancillary testing to confirm germ-line status should precede Li-Fraumeni syndrome management. PMID- 29189825 TI - [Appropriateness and surroundings: "Doing more does not mean doing better". Choosing Wisely, an unfulfilled commitment?] AB - The attention of the medical community to the appropriateness of diagnostic and therapeutic procedures has increased in recent years, recognizing the need for a careful use of resources and for avoiding unnecessary and sometimes harmful medical tests, procedures and therapies. Not only healthcare providers, but also public, patients and politicians, should know the consequences of inappropriate decisions and behaviors. Indeed, inappropriateness has clinical (risks), economic (waste of resources), but also ethical implications (i.e. the use of unnecessary tests and treatments in a system characterized by limited resources).Inappropriateness is a complex entity and it may vary widely: in fact, it may be influenced by different clinical settings, techniques used, but also by data collection methods, size of the population considered, and the professional background of the physicians requesting a specific test or procedure.Various initiatives have been proposed with the aim at reducing the use of unnecessary tests and procedures but imposed rules appear to be of dubious effectiveness. On the contrary, the medical community needs more in-depth knowledge of the problem and an active commitment for reducing the waste of resources, especially because unnecessary or sometimes harmful interventions subtract resources where they are useful or necessary.Recently, the "Choosing Wisely" campaign, which has involved 18 countries and more than 70 scientific societies, has been one of the most well known initiatives, launched in Italy by the "Slow Medicine" movement. The purpose is to disseminate the recommendations of scientific societies with the aim to promote processes of care based on appropriateness, but within a relation of dialogue and decision sharing with the patient and public.The Choosing Wisely campaign is certainly important and innovative. However, there are open and unsolved issues such as the lack of rigorous and systematic methods for the evaluation of the results of the proposed initiatives and the need for more widespread interventions both at the medical and community level.

This extraordinary technological improvement seems to be partly in conflict with the classical tools available for the cardiologist, such as the "old" stethoscope that in 2016 had its 200th anniversary. This article focuses on the smartphone as a new tool available for the physicians, describing the most important potential uses and reporting an analysis of pros and cons of the smart-cardiology.

Nevertheless 10-30% of patients with angina has angiographically normal coronary arteries. In the last 30 years, several studies showed that in these patients the symptoms can be caused by dysfunction of the coronary microcirculation. Coronary microvascular dysfunction (CMVD) occurring in patients affected by specific cardiac or systemic diseases may be due to mechanisms of the underlying disease. On the other hand, in several patients affected by angina with angiographically normal coronary arteries, there is no specific disease, and CMVD only is responsible for the clinical picture. This condition can be defined as leading microvascular angina in order to distinguish it from other forms of microvascular angina where CMVD is related to the presence of a specific disease. As regards pathogenesis, there are still many uncertainties, though evidence suggesting a role for certain risk factors rather than others is gradually emerging, along with the demonstration of new alterations of endothelial function. Also as regards therapy, and prognosis above all, the debate is still open. PMID- 29189828 TI - [Coronary revascularization in patients with ST-elevation myocardial infarction and multivessel disease]. AB - Forty to 60% of ST-elevation myocardial infarction (STEMI) patients present with multivessel coronary artery disease, identified during primary percutaneous coronary intervention (pPCI) of the culprit lesion. At present, data about revascularization of non-culprit coronary lesions are conflicting. Nevertheless, patients with multivessel coronary artery disease have a worse outcome. Recently, several randomized controlled trials and meta-analyses compared a strategy of culprit-only revascularization vs complete revascularization (during pPCI or staged PCI of the non-culprit lesion). The majority of data show a potential benefit of complete revascularization, in particular a reduction in the composite endpoint of major adverse cardiac events, in absence of certain data regarding long-term mortality and reinfarction. Besides, it is still controversial the optimal timing of complete revascularization (during pPCI or staged PCI), as well as the best method for evaluating the lesions to be treated (angiographic vs functional assessment of ischemia). Considering all these data, the only tested and safe approach to treat multivessel coronary artery disease patients remains optimization of medical therapy with long-term prescription of newer antiplatelet agents (ticagrelor and prasugrel) and aggressive lipid-lowering therapy (LDL <70 mg/dl). At the same time, a complete coronary revascularization strategy with PCI, especially guided by ischemia and based on patient lesions and comorbidity, may further improve outcomes.

However, although the diagnosis and management have radically changed in recent years, the disease remains progressive and often fatal. The purpose of this paper is to review and discuss the results of the main clinical trials and the future perspectives of combination strategies for the treatment of pulmonary arterial hypertension.

AB - BACKGROUND: Cardiac rehabilitation (CR) is a model of care proven to reduce mortality and morbidity in patients with coronary artery disease. The aim of this study is to describe the ambulatory CR model of the Cardiovascular Department of Trieste (Italy), analyzing the outcome of the population. METHODS: We analyzed clinical and instrumental characteristics of all consecutive patients after ST elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI), coronary artery bypass graft with or without valve surgery (CABG/CABGV), or planned percutaneous coronary intervention (PCI), referred for CR from January 1, 2009, to December 31, 2015. All patients were included in a registry. During CR and at 1-year follow-up, the incidence of new hospitalizations due to cardiovascular causes was assessed. Total and cardiovascular mortality was also evaluated at longer follow-up. RESULTS: Overall, 3088 patients (28% female, mean age 70 +/- 11 years; 35% older than 75 years) were referred for CR, 30% after STEMI, 23% after NSTEMI, 29% after CABG/CABGV, and 19% after PCI. At enrollment, 9% of patients had an ejection fraction <40%, 76% were hypertensive, 61% dyslipidemic, 19% diabetics, and 27% smokers. CR lasted 5 +/- 4 months. At the end of the CR program, 96% of patients were on antiplatelets, 79% on beta-blockers, 73% on angiotensin-converting enzyme inhibitors, 25% on angiotensin II receptor blockers, and 87% on statins with achievement of the following secondary prevention targets: LDL cholesterol 85 +/- 30 mg/dl, glycated hemoglobin 7.2 +/- 4%, heart rate 64 +/- 11 bpm, systolic/diastolic blood pressure 137 +/- 32/78 +/- 14 mmHg. During CR, new hospitalizations occurred in 11% of patients, 1% within 1 year after CR. At a mean follow-up of 4.4 +/- 2 years, 11% of patients died, 3% for cardiovascular causes, 0.7% within 1 year. Cardiovascular mortality was significantly higher in elderly patients (6 vs 2%, p=0.000), women (4 vs 3%, p=0.038), diabetics (5 vs 3%, p=0.004), and in patients with left ventricular dysfunction (8 vs 3%, p=0.000). CONCLUSIONS: Our findings show the feasibility of a CR program in an unselected population, characterized by advanced age, risk factors and comorbidities. A critical analysis of the registry data allowed us to achieve good results in secondary prevention and outcomes.

AB - Newer generation of self-expandable nitinol coronary stents has proven to be useful in the treatment of bifurcations, tapered vessels, thrombotic lesions, venous grafts and ectatic segments. However, optimal device positioning can be cumbersome, due to the peculiar delivery mechanism which consists of retracting an outer sheath in order to release the stent from the distal edge. We report the case of a 53-year-old man, admitted for unstable angina. Coronary angiography showed a tight stenosis of the proximal left anterior descending coronary artery. As the lesion was located in an ectatic segment of the vessel, we chose to implant a StentysTM (Stentys S.A., Paris, France) device. During the release, the stent jumped forward, resulting in geographic miss. We describe the technique used to retrieve the stent and how we re-deployed it in the proper position; moreover, we examine the lesion characteristics which fostered the migration of the self-apposing stent along the vessel.

AB - Papillary fibroelastoma, a benign cardiac tumor, is a rare clinical condition. Before the echocardiography era, the diagnosis was often occasional, especially during other cardiac procedures; but nowadays it has improved with the advent of higher-resolution imaging technology. The clinical presentation can vary from asymptomatic to severe complications such as cerebrovascular or ischemic events due to tumor embolization.We present the case of a 33-year-old female with a papillary fibroelastoma on the anterior leaflet of the mitral valve undergoing clinical examination for claudicatio intermittens. An occlusion of the left common femoral artery was present. The diagnosis was made posteriorly after embolectomy. All cardiac imaging investigations were negative. The heart team decided a strict echocardiographic follow-up every 3 months, and after the first visit a pedunculated mass was detected on the anterior mitral leaflet. The surgical management included urgent resection of the tumor on cardiopulmonary bypass using a minimally invasive approach via a right anterior minithoracotomy. The postoperative course was uneventful. We emphasize the need for surgical treatment given the potential risk of relapse. When no mass is detected on imaging, a strict echocardiographic follow-up and antiplatelet therapy are mandatory.

AB - Polyketide synthases (PKSs) have several known editing mechanisms to ensure that non-productive intermediates are removed from the acyl carrier protein (ACP). We demonstrate that CitA, a putative hydrolase in the citrinin biosynthetic gene cluster, removes ACP-bound acyl intermediates. We propose that it serves an editing role in trans.

AB - We discuss the origin of Warburg's impedance in unsupported electrolytic cells containing only one group of positive and one group of negative ions. Our analysis is based on the Poisson-Nernst-Planck model, where the generation recombination phenomenon is neglected. We show that to observe Warburg-like impedance the diffusion coefficient of the positive ions has to differ from that of the negative ones, and furthermore the electrodes have to be not blocking. We assume that the non-blocking properties of the electrodes can be described by means of an Ohmic model, where the charge exchange between the cell and the external circuit is described by means of an electrode conductivity. For simplicity we consider a symmetric cell. However, our analysis can be easily generalized to more complicated situations, where the cell is not symmetric and the charge exchange is described by the Chang-Jaffe model, or by a linearized version of the Butler-Volmer equation. Our analysis allows justification of the expression for Warburg's impedance proposed previously by several groups, based on wrong assumptions.

AB - A cell-imprinted poly(dimethylsiloxane)/hydroxyapatite nanocomposite substrate was fabricated to engage topographical, mechanical, and chemical signals to stimulate and boost stem cell osteogenic differentiation. The physicochemical properties of the fabricated substrates, with nanoscale resolution of osteoblast morphology, were probed using a wide range of techniques including scanning electron microscopy, atomic force microscopy, dynamic mechanical thermal analysis, and water contact angle measurements. The osteogenic differentiation capacity of the cultured stem cells on these substrates was probed by alizarin red staining, ALP activity, osteocalcin measurements, and gene expression analysis. The outcomes revealed that the concurrent roles of the surface patterns and viscoelastic properties of the substrate provide the capability of directing stem cell differentiation toward osteogenic phenotypes. Besides the physical and mechanical effects, we found that the chemical signaling of osteoinductive hydroxyapatite nanoparticles, embedded in the nanocomposite substrates, could further improve and optimize stem cell osteogenic differentiation. PMID- 29189840 TI - Hydrogen sorption efficiency of titanium decorated calix[4]pyrroles. AB - Hydrogen is a promising and the most environmentally friendly energy carrier due to its renewable nature and it is expected to replace fossil fuels. The hydrogen storage properties of Ti decorated calix[4]pyrrole (CXP) and octamethylcalix[4]pyrrole (MeCXP) have been reported. The structure, stability and hydrogen loading efficiency of Ti decorated CXP and MeCXP have been studied based on density functional theory with the Minnesota 06 (M06) functional and the 6-311G(d,p) basis set. Ti binds with the pyrrole rings of CXP and MeCXP from outside of each ring by Dewar coordination. It is found that Ti decorated CXP and MeCXP have hydrogen wt% 9.7 and 10.5 respectively. The usable hydrogen wt% is found to be 6.35 and 5.20 for CXP and MeCXP respectively. The stability of Ti decorated CXP and MeCXP is studied by calculating global reactivity parameters, which follow maximum hardness and minimum philicity principles. The calculated adsorption and desorption energy values are found to be low and decrease on H2 adsorption in both the Ti decorated systems. The molecular dynamics simulations indicate that the hydrogen starts releasing at 273 K and all the hydrogen molecules are released by 473 K from both the systems. These predictions pave the way to reversibly store hydrogen efficiently with high gravimetric storage capacity in CXP and MeCXP systems. PMID- 29189841 TI - Probing electron transfer between hemin and riboflavin using a combination of analytical approaches and theoretical calculations. AB - Extracellular electron transfer (EET) occurs from outer-membrane proteins to electron acceptors. Heme(ii) is the active center of outer-membrane proteins and delivers electrons to acceptors or mediators such as riboflavin, a redox active chromophore present in organisms. However, the EET mechanism via mediators, especially the electron transfer process from outer-membrane proteins to mediators, has not been well documented yet. In this work, the mechanism behind the electron transfer from heme(ii) to riboflavin is investigated by using in situ ultraviolet visible and fluorescence spectroelectrochemical analysis, which provides the information regarding the structural change and electrochemical characteristics of species in the electron transfer process. It is found that hemin(iii), the oxidized form of heme(ii), is electrolyzed to an intermediate "hemx(ii)" without structural changes, and is then transformed to heme(ii) by conjugating with riboflavin and its radicals. Heme(ii) is able to activate riboflavin reduction via a two-electron two-proton pathway in aqueous solution. The mechanisms proposed on the basis of experimental results are further confirmed by density functional theory calculations. The results about the electron transfer from hemx(ii) (or heme(ii)) to riboflavin are useful not only for understanding the EET mechanisms, but also for maximizing the role of riboflavin in biogeochemical cycling and environmental bioremediation.

AB - In a macrocyclic terbium complex incorporating a biaryl sensitiser, the observed variation of emission lifetime is shown to be determined by the solubility of oxygen in the solvent system and the relative energy of the chromophore excited state, rather than any dependence on solvent viscosity. PMID- 29189847 TI - Theoretical exploration of the potential applications of Sc-based MXenes. AB - Herein, we systematically explored the electronic properties of Sc-based MXenes via first-principles calculations, with the aim to extend their applicability. OH Functionalized carbides and OH/SH-terminated nitrides manifest ultralow work functions, potential in field-effect transistors. Furthermore, we identified three novel semiconductors (Sc2CCl2, Sc2C(SH)2, and Sc2NO2). Specifically, Sc2NO2 is a spin gapless semiconductor, promising for spintronics. Type-II heterojunctions are readily available between Sc-based semiconducting MXenes, facilitating charge separation for optoelectronics and solar energy conversion. Further photocatalytic analysis indicates that Sc2CCl2 is capable of oxidizing H2O into O2. PMID- 29189851 TI - Plasmon-mediated cancer phototherapy: the combined effect of thermal and photodynamic processes. AB - A nanoplatform for simultaneous cellular imaging, and photodynamic and photothermal therapies has been designed and realized by embedding a purposely synthesized highly luminescent water soluble iridium(iii) compound into gold core silica shell nanoparticles. These multifunctionalities arise mainly from the photophysical properties of the cyclometalated complex: (i) the heavy atom promotes, through excited triplet state formation, energy transfer processes towards molecular oxygen, with the generation of 1O2 (photodynamic effect); (ii) the overlap of the iridium(iii) complex emission band with the plasmonic resonance of gold nanostructures allows excitation energy transfer towards the metallic core (photothermal effect); (iii) the remarkable iridium(iii) complex luminescence feature, which is preserved despite energy transfer processes, makes the whole system an efficient luminescent bio-probe (imaging). Photophysical and photothermal investigations have been carried out, whereas in vitro photo cytotoxicity tests have been performed on human glioblastoma cells (U87MG), highlighting significant cancer cell death at a very low photosensitizer concentration (<0.5 MUM), by means of a synergistic photodynamic and photothermal effect. PMID- 29189852 TI - Assessment of left atrial function in patients with type 2 diabetes mellitus with a disease duration of six months. AB - INTRODUCTION: Changes in left atrial (LA) size and function are associated with adverse clinical events. Recently, duration of diabetes mellitus (DM2) has been found to be positively associated with increased LA volume and impaired LA function. This study was performed, using two-dimensional echocardiograpy, to evaluate the changes in LA volume and function in patients with DM2 with a disease duration of six months, and to assess the parameters that affect LA volume and function. METHODS: Fifty-six patients (28 male, age: 52.6 +/- 6.5 years) with DM2 and 56 controls (24 male; age: 50.1 +/- 7.0 years) were enrolled in the study. Each subject underwent conventional two-dimensional echocardiography to assess LA volume (indexed maximal LA volume: Vmax, pre-atrial contraction volume: Volp, minimal LA volume: Vmin) and LA function [passive emptying volume - passive emptying fraction (PEV - PEF), active emptying volume - active emptying fraction (AEV - AEF), total emptying volume - total emptying fraction (TEV - TEF) ]. RESULTS: LA diameter, indexed Vmax, Volp, Vmin, AEV and TEV were found to be significantly higher in the DM2 group compared with the controls (p < 0.05). Indexed Vmax, Volp and Vmin were significantly correlated with HbA1c level, body mass index (BMI), high-sensitivity C-reactive protein and uric acid levels, mitral A wave, E/E' ratio and A' wave. According to multivariate analysis, age and BMI had a statistically significant effect on LA volume. CONCLUSION: Impaired LA function may be present in patients with newly diagnosed DM2. BMI and increasing age caused LA enlargement and LA volumes that were independent of the effects of hypertension and DM2.

AB - BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with high rates of death, ischemic stroke and systemic embolism (SE). There is scarce information about clinical characteristics and use of anti thrombotic therapies in Chilean patients with non-valvular AF. AIM: To describe the characteristics and 1-year outcomes of patients with recently diagnosed AF recruited in Chile into the prospective global GARFIELD-AF registry. MATERIAL AND METHODS: Between 2011-2016, we prospectively registered information of 971 patients recruited at 15 centers, 85% of them from the public system and 15% from the private sector. Demographics, clinical characteristics and use of antithrombotic therapies were recorded for all patients. Adverse clinical outcomes were analyzed in 711 patients with 1-year follow-up. RESULTS: The mean age was 71.5 years (66-79), 50% were men. Mean CHAD2S2 Vasc and HAS BLED scores for stroke risk were 3.3 (2.0-4.0) and 1.5 (1.0-2.0) respectively. Oral anticoagulants were prescribed in 82% of patients. Seventy percent received Vitamin K antagonists, 10% novel direct anticoagulants or antiplatelet therapy and only 8% did not receive any antithrombotic therapy. Mean time in optimal therapeutic range (an international normalized ratio of 2 to 3), was achieved in only 40.7% (23.0-54.8) of patients receiving Vitamin K antagonists. One year rates of death, stroke/systemic embolism and bleeding were 4.75 (3.36-6.71), 2.40 (1.47-3.92) and 1.64% (0.91-2.97) per 100 person-years. Ischemic stroke occurred in 1.8% and hemorrhagic stroke in 0.8% of patients at 1-year of follow up. CONCLUSIONS: Although the use of vitamin K antagonists at baseline was high, the mean time in optimal therapeutic range was low. Mortality and stroke rates are higher than those reported in other contemporary registries. PMID- 29189854 TI - [Effects of a high intensity interval training on the aerobic capacity of adolescents]. AB - BACKGROUND: If aerobic capacity is stimulated early in life, maximal oxygen consumption during adulthood is assured. AIM: To analyze the effects of a high intensity interval training (HIIT) in adolescents on the maximal oxygen consumption (VO2max) measured using the 20-m shuttle run test (20mSRT). MATERIAL AND METHODS: Twenty eight teenagers aged 13 +/- 0.6 years were divided in two groups of 14 subjects each. One group was to a 16 sessions of HIIT interval training based on their individual maximal aerobic speed and the other continued with their usual exercise done at school. At baseline and the end of the intervention VO2max was measured using the 20mSTR. RESULTS: At the end of the intervention, the trained teenagers significantly improved their VO2max and the time spent in the 20mSTR. CONCLUSIONS: A HIIT program based on the individual maximal aerobic speed improves VO2max in adolescents.

In 2015, Puerto Montt Hospital in Chile faced a simultaneous outbreak of both seasonal H3N2 and H1N1pdm09 influenza A (IA). AIM: To evaluate the clinical differences between the two viral strains and recent changes in the behavior of H1N1pdm09 IA. MATERIAL AND METHODS: We set up a retrospective study including every adult hospitalized in Puerto Montt Hospital in 2015 due to IA, confirmed by reverse transcription polymerase chain reaction. We compared epidemiological data, clinical presentation, complications, and the outcome of patients with H1N1pdm09 versus those with seasonal influenza. In parallel, we compared 62 cases of thatH1N1 IA from 2015 with 100 cases who were hospitalized and analyzed in 2009. RESULTS: Between July and October 2015, 119 adults with confirmed IA were hospitalized. From 2009 to 2015, the mean age of patients with IAH1N1pdm09 increased from 40.4 +/- 17 to 58.8 +/- 16 years (p < 0.01). Pneumonia as the cause of hospitalization decreased from 75 to 58% of patients, (p = 0.04). Likewise, the presence of comorbidities increased from 53 to 74%, (p < 0.01). Compared with seasonal H3N2, patients with IAH1N1pdm09 IA were more likely to require intensive care (p < 0.01) and mechanical ventilation (p < 0.01) and developed septic shock (p = 0.03). Their mortality was non-significantly higher (13 and 5% respectively). CONCLUSIONS: The clinical presentation of H1N1pdm09 IA has varied over time and now affects an older population, with a greater number of comorbidities. It also appears to be adopting the clinical behavior of a classic seasonal influenza virus. PMID- 29189856 TI - [The impact of the orthopedic surgeons' attire on patient preferences]. AB - BACKGROUND: The formal appearance of health care professionals may influence their trustworthiness. AIM: To determine the effect of the orthopedic surgeon's attire on patients' perceptions of credibility and reliability of professionals. MATERIAL AND METHODS: In a cross-sectional design, 351 patients (mean age 43 +/- 17 years, 62% males) from the Department of Orthopedics and Traumatology of a Chilean regional hospital in southem of Chile were chosen to complete a questionnaire of attire preferences, in which five photographs with male and female orthopedic surgeons appeared (executive, formal attire, informal attire, scrubs and casual clothing). The influence of attire in the perception of physicians' trustworthiness to resolve medical situations was analyzed. RESULTS: Forty four percent of patients had no physician gender predilection (p = 0.32). Forty three percent of male and 38% of female patients preferred the use of formal attire. In situations of credibility or confidence, all patients chose mostly the use of white coats with formal attire by professionals. The probability of choosing an orthopedic surgeon with a formal attire was significantly higher among patients who considered the attire and appearance of the professional to be very important (Odds ratio = 3.74; p < 0.01). CONCLUSIONS: Patients prefer orthopedic surgeons wearing white coats and formal attire, which improves credibility of these professionals to correctly solve medical situations. PMID- 29189857 TI - [Risk factors associated with hypertension. Analysis of the 2009-2010 Chilean health survey]. AB - BACKGROUND: High blood pressure is one of the major risk factors for the development of cardiovascular disease, affecting 27% of the Chilean population in 2010. AIM: To determine the risk factors associated with the development of hypertension. MATERIAL AND METHODS: Analysis of the database of the 2009-2010 National Health Survey in which 4,901 participants were included. Socio demographic factors, physical activity, eating habits, well-being and comorbidities were analyzed. RESULTS: Women had a lower risk of developing hypertension than men (Odds ratio (OR): 0.69, 95% confidence intervals (CI): 0.59 0.81, p < 0.01). In both men and women, the risk is greater over the age of 25 years (OR: 2.90, 95% CI: 1.55-5.43, p < 0.01). The risk is greater in subjects who were overweight (OR: 1.61, 95% CI: 1.31-1.98, p < 0.01), obese (OR: 3.18, 95% CI: 2.56-3.95, p < 0.01), or had central obesity (OR: 2.25, 95% CI: 1.85-2.72, p < 0.01). Subjects with a family history of hypertension and diabetes also have a higher risk. CONCLUSIONS: Identifying the risk factors associated with hypertension allows public health policies to be tailored to its prevention. PMID- 29189858 TI - [Psychometric properties of a spanish version of the Beck depression inventory IA]. AB - BACKGROUND: According to the Chilean National Health Survey (2009-2010), 17% of people aged 15 years or more have depressive symptoms. Thus, freely-available, easily-administered, and highly sensitive screening tests for depression are needed in clinical and research settings. AIM: To evaluate the psychometric properties of a Spanish version of the Beck Depression Inventory (BDI-IA) in adult Chilean population. MATERIAL AND METHODS: The inventory was applied to a sample of 1.105 adults aged between 18 to 73 years (94% women). Ninety nine participants were outpatients receiving treatment for affective disorders, 932 were parents and/or guardians of students enrolled in schools and 73 were university students (sample with no known depressive disorder). To perform data analysis, two groups from the random combination of both samples were generated. RESULTS: The inventory showed an appropriate degree of internal consistency (Cronbach alpha = .92). An exploratory factor analysis suggested a one-factor solution. This solution was reinforced with a confirmatory factor analysis, which displayed an adequate goodness of fit. The cutoff score, based on the Youden Index, was 13/14 points. It was able to discriminate between depressed and non depressed participants. CONCLUSIONS: These results indicate that the BDI-IA is an appropriate instrument to assess depressive symptoms in Chilean adults. PMID- 29189859 TI - [Is abortion a serious public health problem in Chile in the field of maternal perinatal health?] AB - BACKGROUND: The World Health Organization, by 2014, estimates that approximately 22 million unsafe abortions take place every year in the world, almost all of them in developing countries. The Millennium Goals, as part of the fifth compendium, focused on maternal health by proposing that member states should reduce maternal mortality to 75% by 2015. AIM: To determine, using maternal health indicators, if abortion in Chile is a priority health problem. MATERIAL AND METHODS: Data about maternal mortality and its causes between 1982 and 2014, was obtained from the databases available at the Chilean Ministry of Health. Trend analyzes were carried out using linear autoregressive models. RESULTS: Between 1982 and 2012, maternal mortality rates decreased from 51.8 to 18.3 per 100,000 live births. Complications of pregnancy, childbirth and puerperium were the first three causes and the last one is abortion. The proportion of abortions due to unspecified causes, including induced abortion, decreased from 36.6% to 26.1% between 2001 and 2012. CONCLUSIONS: Abortion is not a public health problem in Chile. To continue reducing maternal mortality, programs for the early detection of risks such as diabetes, obesity and hypertension should be implemented.

AB - BACKGROUND: 99mTc-sestamibi parathyroid SPECT scintigraphy is a useful tool in the pre-operative study of hyperparathyroidism. False negatives (FN) have been reported in 5.7-14% of the examinations. AIM: To characterize 99mTc-sestamibi FN in cases referred for primary hyperparathyroidism (PHP) to a university hospital. MATERIAL AND METHODS: Descriptive retrospective analysis. We included patients with PHP, studied with SPECT scintigraphy, operated at our center between 2008 and 2015. Clinical and surgical data were recorded; biopsies of the FN were blindly reviewed by one pathologist. RESULTS: One hundred twenty one scintigraphies fulfilled the inclusion criteria. Seven (5.8%) were negative and 114 positive. There was no difference in age, sex and PTH levels between FN and true positive scintigraphies. At surgery, one FN case had two hyperplasic glands and two cases had ectopic glands. Pathology reported adenoma in three cases, hyperplasia in three and carcinoma in one. The largest diameter of the lesion was lower in FN (1.3 and 2.1 cm respectively, p = 0.02) and the proportion of adenomas was higher in true positive cases (29% and 75% respectively; p < 0.01). The interval between scintigraphy and parathyroidectomy was greater in FN with a median of 92 days (range 20 days-3.2 years, p < 0.01). The percentage of oxyphilic cells observed was similar in both groups. CONCLUSIONS: FN parathyroid SPECT scintigraphies in PHP are uncommon. They corresponded to lesions under the equipment's resolution limit and resulted in longer time lags between scintigraphy and surgery. PMID- 29189861 TI - [Study and management of thyroid nodes by non specialist physicians: SOCHED consensus]. AB - The thyroid nodule is a frequent cause of primary care consultation. The prevalence of a palpable thyroid nodule is approximately 4-7%, increasing up to 67% by the incidental detection of nodules on ultrasound. The vast majority are benign and asymptomatic, staying stable over time. The clinical importance of studying a thyroid nodule is to exclude thyroid cancer, which occurs in 5 to 10% of the nodules. The Board of SOCHED (Chilean Society of Endocrinology and Diabetes) asked the Thyroid Study Group to develop a consensus regarding the diagnostic management of the thyroid nodule in Chile, aimed at non-specialist physicians and adapted to the national reality. To this end, a multidisciplinary group of 31 experts was established among university academics, active researchers with publications on the subject and prominent members of scientific societies of endocrinology, head and neck surgery, pathology and radiology. A total of 14 questions were developed with key aspects for the diagnosis and subsequent referral of patients with thyroid nodules, which were addressed by the participants. In those areas where the evidence was insufficient or the national reality had to be considered, the consensus opinion of the experts was used through the Delphi methodology. The consensus was approved by the SOCHED board for publication. PMID- 29189862 TI - [Management of facial injuries in the emergency room]. AB - Facial injuries are cause of consultation in emergency departments. The maxillofacial region contains several structures that are vital for life. Hence, an early assessment and management of facial injuries is important to avoid their consequential complications and eventual mortality. This article is a review of the literature about the emergency clinical assessment and management of traumatic facial injuries by non-specialists. PMID- 29189863 TI - [The association of schizophrenia with chronic non transmissible diseases]. AB - The life expectancy of patients with schizophrenia (SCH) is 11 to 20 years less than the general population. There is an association between SCH and various diseases and chronic conditions, highlighting the cardio-metabolic diseases. This association has been attributed to the use of antipsychotics, however, evidence has also shown intrinsic susceptibility of schizophrenic patients the development of chronic conditions. This review aims to update knowledge about chronic conditions such as cardiometabolic risk and sleep, bone and kidney disorders related to SCH. These patients have a high prevalence of risk behaviors, including smoking and poor diet. They have a worse metabolic profile than the general population and a greater likelihood of developing metabolic syndrome, diabetes and cardiovascular disease. SCH has also been associated with other chronic diseases such as osteoporosis and chronic kidney disease. The high prevalence of these comorbidities in schizophrenic population is not explained solely by the antipsychotic treatment, therefore intrinsic mechanisms associated to SCH are postulated to be associated with these conditions. This new information requires a change in the multidisciplinary medical approach for the study and management of schizophrenic patients. PMID- 29189864 TI - [The potential contribution of adenovirus 36 to the development of obesity]. AB - The evidence of the last 20 years shows a link between viral infections and obesity in animals and humans. There are five adenovirus which have been associated with development of obesity in animals. SMAM-1 virus was the first studied in humans associated with obesity. There is compelling evidence that Ad 36 virus could contribute to the development of obesity in humans and it is related with body mass index (BMI). This manuscript reviews the association between Ad-36 and the other four virus infections with obesity. An electronic search of articles in the databases PubMed and Scielo, with use of key words: obesity, infection, adipose tissue, Ad-36, 3T3-L1 was performed. The search was restricted "human" and "animals". The importance of the relationship between virus infections and obesity has increased over the past two decades. Ad-36 shows more compelling evidence in humans. There are reports involving this virus in the enhancement of adipogenesis, adipocyte differentiation, a lower secretion of leptin and an increased insulin sensitivity. Future work should focus in larger cohort studies to confirm this association, which explains the global obesity epidemic from a new perspective.

AB - The aim of this manuscript is to highlight the contribution of the first two generations of physicians who faced malnutrition in Chile, between the end of nineteenth century and the first decades of the twentieth century. In the history of Chilean medicine, there is a paucity of research about the role of these physicians in the fight against malnutrition. The main interest was centered in the forties of the twentieth century and the first policies and actions for the working class feeding have been overlooked. The existence of two pioneering groups that have common elements and differences to face the problem of under nutrition is established.

AB - Saprochaete capitata (S. capitata) fungal sepsis is a severe condition with a clinical presentation that is similar to other yeast originated fungal sepsis. It is observed in patients with hematological malignancies such as acute myeloid leukemia and neutropenia. We report a 23 year old male presenting with cough, fever and malaise. A bone marrow biopsy led to the diagnosis of acute myeloid leukemia. During the first cycle of chemotherapy the patient presented fever: blood cultures were positive for Klebsiella pneumoniae. Despite antimicrobial treatment, fever persisted; a computed tomography showed a focal splenic lesion; a left exudative pleural effusion appeared. A Matrix Assisted Laser Desorption Ionization-Time of Flight mass spectrometry identified the presence of S. capitata. After multiple antifungal treatments and pleural cavity cleansing by means of videothoracoscopy and laparoscopic splenectomy, the infection resolved and the patient completed his chemotherapy.

Early diagnosis is essential to start an early treatment, which often has favorable results. We report a 56 years old non-insulin-requiring type 2 diabetic female who developed a severe metabolic acidosis associated with metformin in relation to an acute renal failure secondary to infectious diarrhea. Early treatment with bicarbonate and continuous hemofiltration allowed a quick improvement of the patient. Metformin-associated lactic acidosis has an elevated mortality (50-80%) and has a specific and effective treatment. Therefore, the condition must be born in mind. PMID- 29189868 TI - [Breast osteosarcoma originating in a phyllodes tumor. Report of one case]. AB - Phyllodes tumors account for less than 1% of tumors of the mammary gland, have both epithelial and stromal components and are classified as benign, borderline and malignant. The malignant tumors are highly heterogeneous: they can differentiate to liposarcomas, fibrosarcomas, rhabdomyosarcomas, chondrosarcomas or osteosarcomas. The differentiation to osteosarcoma is extremely rare, constitutes 1.3% of cases and is very aggressive. The standard treatment of these tumors is surgical. The role of radiotherapy and chemotherapy is not clear. However, in patients in whom wide surgical margins are not achieved, adjuvant radiotherapy can be of help. We report a 63 years old female with a right breast osteosarcoma with an osteoclastic component, originating in a phyllodes tumor. The tumor was excised surgically and afterwards she was treated with 10 sessions of 50 Gy of radiotherapy in 25 fractions. She has remained free of disease for the last 10 months. PMID- 29189869 TI - [Acute severe ulcerative colitis treated with accelerated infliximab induction. Case report]. AB - Acute severe ulcerative colitis (ASUC) is a potentially life-threatening condition that requires early recognition, hospitalization and adequate treatment. Currently, the use of infliximab in ulcerative colitis (UC) is recommended in the case of severe disease refractory to corticosteroids, once that superimposed bacterial or viral infections (such as cytomegalovirus or Clostridium difficile) have been excluded. However, conventional weight-based regimens of infliximab might be insufficient for patients with ASUC. Accelerated infliximab induction regimen may increase its serum concentration levels and efficacy by reducing early colectomy rates in these patients. We report a 34 year old female presenting with an ASUC. She was initially treated with hydrocortisone 300 mg/day and mesalazine enemas 4 g/day with an unfavorable clinical response. At the fifth day of therapy, an accelerated induction therapy with infliximab was started in doses of 10 mg/kg at weeks 0, 1 and 4. After the second dose, there was a favorable response with reduction of abdominal pain, stool frequency and hematochezia. She was discharged with prednisone and azathioprine. After a year of starting infliximab, the patient remains in clinical remission.

PMID- 29189872 TI - [How frequently are depressive disorders recognized in primary care patients? : A cross-sectional epidemiological study in Germany]. AB - BACKGROUND: Primary care physicians (PCPs) play a crucial role for guideline oriented intervention in patients with depression. OBJECTIVES: Based on a diagnostic screening questionnaire, this study investigates the sensitivity of PCPs to recognize patients with depression as well as the factors facilitating recognition and concordant diagnostic decisions. METHOD: In a cross-sectional epidemiological study in six regions of Germany, 3563 unselected patients filled in questionnaires on mental and physical complaints and were diagnostically evaluated by their PCP (N = 253). The patient reports on an established Depression-Screening-Questionnaire (DSQ), which allows the approximate derivation of an ICD-10 depression diagnosis, were compared with the physician diagnosis (N = 3211). In a subsample of discordant cases a comprehensive standardized clinical diagnostic interview (DIA-X/CIDI) was applied. RESULTS: On the study day, the prevalence of ICD-10 depression was 14.3% according to the DSQ and 10.7% according to the physician diagnosis. Half of the patients identified by DSQ were diagnosed with depression by their physician and two thirds were recognized as mental disorder cases. More severe depression symptomatology and the persistent presence of main depression symptoms were related to better recognition and concordant diagnostic decisions. Diagnostic validation interviews confirmed the DSQ diagnosis in the majority of the false-negative cases. Indications for at least a previous history of depression were found in up to 70% of false-positive cases. CONCLUSION: Given the high prevalence of depression in primary care patients, there is continued need to improve the recognition and diagnosis of these patients to assure guideline-oriented treatment.

PMID- 29189879 TI - [Vascular anomalies. Part I: vascular tumors]. AB - Vascular anomalies represent a spectrum of structural disorders and inborn errors of vascular morphogenesis, which may affect the entire arterial and venous vascular tree. They are divided into two major categories: tumors, which exhibit endothelial hyperplasia and malformations, which have normal endothelial turnover unless disturbed. Depending on their nature and complexity they can range from a simple "birthmark" to life-threatening entities. The relatively low incidence (4 10%) of vascular anomalies among the general population combined with the fact that their management often falls within the purview of several different medical and surgical specialties, has traditionally resulted in insufficient expertise in the management of these conditions. Therefore, accurate identification, a uniform nomenclature and a multidisciplinary approach are paramount for correct management. PMID- 29189878 TI - [Quality indicators for colon cancer surgery : Evidence-based development of a set of indicators for the outcome quality]. AB - BACKGROUND: Quality assessment in surgery is gaining in importance. Although sporadic recommendations for quality indicators (QI) in oncological colon surgery can be found in the literature, these are usually not systematically derived from a solid evidence base. Moreover, reference ranges for QI are unknown. OBJECTIVE: The aim of this initiative was the development of evidence-based QI for oncological colon resections by an expert panel invited by the German Society of General and Visceral Surgery (DGAV). Reference ranges from the literature and reference values from the Study, Documentation, and Quality Center (StuDoQ)|Colon Cancer Register were compared in order to deduce recommendations which are tailored to the German healthcare system. RESULTS: Based on the most recent scientific evidence and agreed by expert consensus, five QI for oncological colon surgery were defined and evaluated according to the QUALIFY tool. Mortality, MTL30 (mortality, transfer to another acute care hospital, or length of stay >=30 days), anastomotic leakage requiring reintervention, surgical site infections necessitating reopening of the wound and >=12 lymph nodes in the specimen qualified as QI owing to their relevance, scientific nature, and practicability. Based on the results of the systematic literature search and the statistical analysis of the StuDoQ|Colon Cancer Register, preliminary reference values are proposed for each QI. CONCLUSION: The presented set of QI seems appropriate for quality assessment of oncological colon surgery in the context of the German healthcare system. The validity of the QI and the reference values must be reviewed within the framework of their implementation. The StuDoQ|Colon Cancer Register provides a suitable infrastructure for collecting clinical data for quality assessment and risk adjustment. PMID- 29189880 TI - [Sexual health in flux]. PMID- 29189881 TI - Satisfactory functional and radiological outcomes can be expected in young patients under 45 years old after open wedge high tibial osteotomy in a long-term follow-up. AB - PURPOSE: To report the long-term outcomes of medial open wedge high tibial osteotomy (MOWHTO) for the treatment of medial compartment knee osteoarthritis in patients younger than 45 years old. It was hypothesized that the correction of knee alignment would result in preservation of knee function in a long-term follow-up. METHODS: Patients under 45 years old, who underwent MOWHTO for symptomatic medial compartment knee osteoarthritis between 2001 and 2005 were retrospectively reviewed after a minimum of 10 years. The osteotomy was performed utilizing a locking plate without the use of bone graft. Patients were evaluated pre- and postoperatively using the International Knee Documentation Committee Score, the Oxford Knee Score, the Knee injury Osteoarthritis Outcome Score and the Short Form-12 Score. Standardized standing whole-limb radiographs were also obtained to assess mechanical tibiofemoral angle (mTFA) and the grade of osteoarthritis. RESULTS: A total of 20 patients (18 males, 2 females, mean age 35.4 years) with a mean follow-up of 12.3 years were included in the study. During the follow-up period, one patient required conversion to total knee replacement (95% survival rate). All clinical outcome scores (IKDC, KOOS, OKS, and SF-12) significantly improved postoperatively (p < 0.05), with no significant deterioration over time. Preoperative varus alignment with an mTFA of - 5.8 +/- 2.4 degrees was corrected to 2.5 +/- 1.9 degrees immediately after surgery (p < 0.05), and remained 2.2 +/- 1.7 degrees at the last follow-up. Furthermore, no significant radiographic progression of osteoarthritis was observed. CONCLUSIONS: MWOHTO with a locking plate is an effective joint preservation method to treat medial compartment OA in active patients less than 45 years. Clinical and radiological results are satisfactory and the survival rate is 95%, 12 years after the procedure. LEVEL OF EVIDENCE: Level IV therapeutic, retrospective, cohort study. PMID- 29189882 TI - The transportal technique shows better clinical results than the transtibial techniques for single-bundle anterior cruciate ligament reconstruction. AB - PURPOSE: Although anatomical and independent drilling techniques, such as transportal (TP) technique, have become more popular in anterior cruciate ligament (ACL) reconstruction, the TP technique has not been shown to yield superior clinical or functional outcomes compared to the transtibial (TT) technique. The aim of the current meta-analysis was to compare clinical outcomes of the TP and TT techniques, as determined by patient-reported outcome scores and knee joint laxity tests. It was hypothesized that the TP and TT techniques of ACL reconstruction would yield similar patient-reported functional outcomes and similar results on knee joint laxity tests. METHODS: Studies were included if they reported at least one of the following clinical outcomes: IKDC score, IKDC examination, Lysholm knee score, and Tegner activity score. Knee stability was evaluated by single or multiple parameters of the following knee laxity examinations: the Lachman test, the pivot shift test, and side-to-side difference on the instrumented knee laxity test. RESULTS: Sixteen studies were finally included in this meta-analysis. The proportions of patients with normal grade on the IKDC examination [odds ratio (OR) 2.23; 95% confidence interval (CI) 1.41 3.53; P = 0.0006] and Lysholm score (mean difference 1.27; 95% CI 0.23-2.31; P = 0.02) after surgery were higher with the TP than with the TT technique, but there were no differences in IKDC and Tegner scores. The postoperative proportion of normal knee joint stability was significantly higher with the TP than the TT technique, on both Lachman (OR 2.29; 95% CI 1.35-3.92; P = 0.002) and pivot shift (OR 2.13; 95% CI 1.12-4.05; P = 0.02) tests. The pooled mean side-to-side difference was 0.73 mm lower with the TP than the TT technique (95% CI - 1.14 to 0.32 mm; P = 0.0005). CONCLUSION: This meta-analysis showed that the clinical outcomes of ACL reconstruction were better with the TP than the TT technique, both on knee functional outcome scales and knee laxity tests. The findings thus suggest that the TP technique would be a better option for single-bundle ACL reconstruction compared to the TT technique. LEVEL OF EVIDENCE: III. PMID- 29189883 TI - Arthroscopic treatment combined with the ankle stabilization procedure is effective for sinus tarsi syndrome in patients with chronic ankle instability. AB - PURPOSE: This study aimed to investigate the results of arthroscopic treatment combined with ankle stabilization procedure for sinus tarsi syndrome (STS) in patients with chronic ankle instability (CAI). METHODS: A total of 57 patients (31 males and 26 females, average age 29.9 +/- 8.4 years ranging from 15 to 52 years) with STS and CAI who accepted operation from 2013 to 2015 were included in this retrospective study. Surgical procedures included thorough tarsal sinus debridement and repair or reconstruction of lateral ankle ligaments according to the quality of ligaments. American Orthopedic Foot and Ankle Society (AOFAS) score, Karlsson score, and Tegner score were evaluated preoperatively and at final follow-up. RESULTS: All the patients accepted thorough debridement of tarsal sinus. Of these, 53 patients (93.0%) had an arch structure between the posterior subtalar joint and the middle subtalar joint. Further, 54 patients accepted lateral ankle ligament repair, and 3 patients accepted ligament reconstruction. A total of 40 patients were followed up with an average time of 30.7 months. The modified AOFAS score increased from 62.5 (27-90) to 93 (67-100), the Karlsson score increased from 57 (30-82) to 90 (55-100), and the Tegner score increased from 1 (1-3) to 5 (1-8). CONCLUSIONS: Arthroscopic treatment combined with the ankle stabilization procedure could get satisfactory results for STS in patients with CAI. The arch structure composed by medial calcaneal component of the medial root of the inferior extensor retinaculum (MCC) might contribute to the pathological mechanism of STS. LEVEL OF EVIDENCE: IV. PMID- 29189884 TI - Adaptive Immune Cell Dysregulation and Role in Acute Pancreatitis Disease Progression and Treatment. AB - Acute pancreatitis (AP) is an inflammation of the pancreas caused by various stimuli including excessive alcohol consumption, gallstone disease and certain viral infections. Managing specifically the severe form of AP is limited due to lack of an understanding of the complex immune events that occur during AP involving immune cells and inflammatory molecules such as cytokines. The relative abundance of various immune cells resulting from the immune dysregulation drives disease progression. In this review, we examine the literature on the adaptive immune cells in AP, the prognostic value of these cells in stratifying patients into appropriate care and treatment strategies based on cell frequency in different AP severities are discussed. PMID- 29189885 TI - Invited review: the tale of ECIRS (Endoscopic Combined IntraRenal Surgery) in the Galdakao-modified supine Valdivia position. AB - Modern-day percutaneous nephrolithotomy (PNL) has undergone considerable evolution, mainly driven by the improvement in access techniques, endoscopic instrumentation technology, lithotripsy devices and drainage management. The introduction of the supine and supine-modified positions is also part of this evolution, enabling comfortable and safe procedures from an anaesthesiological point of view, and an easy combined retrograde surgery [Endoscopic Combined IntraRenal Surgery (ECIRS)], allowing tailoring of the procedure on the patient, the dynamic anatomy of the collecting system and the urolithiasis. The conceptual value of ECIRS extends beyond the single diagnostic and active advantages due to the simultaneous contribution of the flexible retrograde ureteroscopy: the merit consists in the promotion of the versatile attitude of the urologist, and in the fulfillment of a personalized stone management. ECIRS has no pretensions of superiority, but for sure is a new safe and effective way of interpreting PNL, in the hands of an experienced surgical team. PMID- 29189886 TI - Antiurolithiatic effect of the taraxasterol on ethylene glycol induced kidney calculi in male rats. AB - Taraxasterol is one of the important constituents of Taraxacum officinale L. (Compositae) with antioxidant potential. The present study was designed to evaluate and compare the antiurolithiatic effects of taraxasterol and potassium citrate in the ethylene glycol induced urolithiatic rat. Urolithiasis was induced by ammonium chloride and ethylene glycol in adult male rats. Taraxasterol (2, 4 and 8 mg/kg) and potassium citrate (2.5 g/kg) were treated for 33 days by gavage. Then, the animals were anesthetized and weighted and blood, urine, liver and kidney sampling were done. The kidney sections were prepared by hematoxylin & eosin staining. The liver and kidney coefficients, urine pH, calcium, magnesium, oxalate and citrate levels, serum albumin, calcium and magnesium levels, serum alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase activities, superoxide dismutase and glutathione peroxidase activities in serum, kidney and liver, number of calcium oxalate crystal deposits, score of crystal deposits, score of histopathological damages and score of inflammation in kidney sections were evaluated. The results showed that taraxasterol decreased liver and kidney coefficients (p < 0.001), serum calcium (p < 0.01) level, serum alanine aminotransferase (p < 0.001), aspartate aminotransferase (p < 0.001), lactate dehydrogenase (p < 0.05) activities, urine magnesium (p < 0.05) and oxalate (p < 0.001) levels, number of crystal deposits (p < 0.001), score of crystal deposits (p < 0.01), score of histopathological damages (p < 0.001) and score of inflammation (p < 0.01) in kidney sections, while increased urine pH (p < 0.01), calcium (p < 0.001) and citrate (p < 0.05), serum magnesium (p < 0.001) and albumin (p < 0.01) levels, superoxide dismutase and glutathione peroxidase in serum (p < 0.01), kidney (p < 0.05 and p < 0.001, respectively) and liver (p < 0.01 and p < 0.001, respectively) tissue homogenates in treated urolithiatic rats in comparison to the control urolithiatic rats. The effect of potassium citrate is the same as taraxasterol in treated urolithiatic rats. In conclusion, the effect of taraxasterol could be by improving liver function, changing serum and urine parameters, maintaining the antioxidant environment, reducing crystal deposition, excretion of small deposits from kidney and reducing the chance of them being retained in the urinary tract. PMID- 29189887 TI - Eosinophilic granulomatosis with polyangiitis without respiratory symptoms or asthma in an adolescent: case report and literature review. AB - Eosinophilic granulomatosis with polyangiitis (EGPA), also known as Churg-Strauss syndrome, is a systemic necrotizing vasculitis of the small and medium vessels. It is primarily associated with respiratory conditions such as asthma and sinusitis as well as eosinophilia, neuropathy, pulmonary infiltrates, and vasculitis. EGPA is extremely rare in the pediatric age group, and respiratory system disorders are usually predominant in EGPA patients. A 14-year-old boy presented with rash and severe extremity pain. He had eosinophilia, and electroneuromyography demonstrated sensorimotor polyneuropathy. His skin biopsy revealed necrotizing eosinophilic vasculitis and eosinophilic panniculitis. Although he had no respiratory symptoms or history of asthma, prominent pulmonary involvement was evident on thoracic MRI. After treatment, his complaints of pain improved but mild neuropathy persisted. After 4 years of follow-up, he had minimal hypoesthesia in his right hand but had not experienced any relapses. This case highlights the fact that in cases suspected of EGPA, even without respiratory symptoms or asthma, detailed imaging should be performed for a definitive diagnosis. In addition, mild neurological findings may persist despite treatment in EGPA. The relevant literature on EGPA, with specific reference to pediatric cases, is reviewed. PMID- 29189888 TI - On the Early Evolution of Catabolic Pathways: A Comparative Genomics Approach. I. The Cases of Glucose, Ribose, and the Nucleobases Catabolic Routes. AB - Compared with the large corpus of published work devoted to the study of the origin and early development of anabolism, little attention has been given to the discussion of the early evolution of catabolism in spite of its significance. In the present study, we have used comparative genomics to explore the evolution and phylogenetic distribution of the enzymes that catalyze the extant catabolic pathways of the monosaccharides glucose and ribose, as well as those of the nucleobases adenine, guanine, cytosine, uracil, and thymine. Based on the oxygen dependence of the enzymes, their conservation, and evolution, we speculate on the relative antiquity of the pathways. Our results allow us to suggest which catabolic pathways and enzymes may have already been present in the last common ancestor. We conclude that the enzymatic degradations of ribose, as well as those of purines adenine and guanine, are among the most ancient catabolic pathways which can be traced by protein-based methodologies. PMID- 29189889 TI - Is Cr(III) toxic to bacteria: toxicity studies using Bacillus subtilis and Escherichia coli as model organism. AB - The objective of this work is to detect the mode of damage caused by Cr(III), one of the widely used industrial pollutant on Bacillus subtilis-industrial strain 168 and Escherichia coli MTCC 40. Bioassays are very sensitive, precise, economical and rapid for detecting early stages of pollution. The detrimental effect of trivalent chromium becomes clear from the growth profile and growth inhibition studies. Mode of action of damage by trivalent chromium in bacterial model was found to be oxidative, as chromium is one of the redox active metals. The generation of reactive oxygen species (ROS) resulted in membrane damage which in turn had a detrimental effect on the membrane proteins as well as the DNA. The structural changes in the SEM and AFM images clearly reveals the damage caused by Cr(III) to the test bacterial models. Trivalent chromium causes greater DNA, protein and membrane damage in case of E. coli than B. subtilis. Membrane damage caused by ROS becomes evident from the production of Thiobarbituric acid reactive substances (TBARs) as the mechanism of killing followed by DNA damage and the production of elevated levels of stress proteins known as extracellular cellular proteins. PMID- 29189890 TI - Decoding the role of hypothetical protein All3255 of Anabaena PCC7120 in heavy metal stress management in Escherichia coli. AB - Cadmium is a non-essential toxic heavy metal for organisms, including plants and cyanobacteria. Cadmium resistance transporters involved in resistance of cells against various toxicants such as drugs and effluxes cytotoxic compounds from cells. However, cadmium resistance-associated protein (CadD) has never been reported from a diazotrophic cyanobacterium Anabaena sp. To test whether the hypothetical protein All3255 of Anabaena sp. PCC7120 a homolog of cadmium resistance-associated protein (CadD) involved in cadmium or heavy metal resistance or not, cloning and heterologous expression analysis of all3255 performed in Escherichia coli BL21 (DE3). Our results revealed that the strain transformed with pGEX-5X-2 + all3255 showed resistant towards not only to cadmium but also other heavy metals such as nickel, copper, zinc, lead and cobalt in addition to arsenic than those of transformed with empty vector (pGEX-5X-2). Furthermore, the results of metal accumulation analysis of these cells unveil a lower accumulation of tested heavy metals in all3255-overexpressing E. coli cells than those transformed with empty vector. This study strongly supports the role of All3255 of Anabaena sp. PCC7120 as a CadD efflux pump of heavy metals in E.coli.

PMID- 29189891 TI - Coralloluteibacterium stylophorae gen. nov., sp. nov., a new member of the family Lysobacteraceae isolated from the reef-building coral Stylophora sp. AB - A bacterial strain, designated Sty a-1T, was isolated from a reef-building coral Stylophora sp., collected off coast of Southern Taiwan and characterized using the polyphasic taxonomy approach. Cells of strain Sty a-1T were Gram-staining negative, aerobic, poly-beta-hydroxybutyrate accumulating, motile by means of flagella, non-spore forming, straight rod-shaped and colonies were yellow and circular. Growth occurred at 15-40 degrees C (optimum, 30-35 degrees C), at pH 6-10 (optimum, pH 6.5-8) and with 0-7% NaCl (optimum, 2-3%). The predominant fatty acids were iso-C15:0, iso-C17:1 omega9c, summed feature 3 (comprising C16:1 omega7c and/or C16:1 omega6c) and iso-C17:0. The major isoprenoid quinone was Q-8 and the DNA G+C content was 68.5 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, diphosphatidylglycerol, an uncharacterized aminophospholipid and three uncharacterized lipids. The major polyamines were spermidine, putrescine and homospermidine. Phylogenetic analyses based on 16S rRNA and four housekeeping gene sequences (recA, atpD, rpoA and rpoB) showed that strain Sty a-1T forms a distinct lineage with respect to closely related genera in the family Lysobacteraceae, most closely related to Lysobacter, Silanimonas, Arenimonas and Luteimonas and the levels of 16S rRNA gene sequence similarity with respect to the type species of related genera are less than 95%. On the basis of the genotypic and phenotypic data, strain Sty a-1T represents a novel genus and species of the family Lysobacteraceae, for which the name Coralloluteibacterium stylophorae gen. nov., sp. nov. is proposed. The type strain is Sty a-1T (= BCRC 80968T = LMG 29479T = KCTC 52167T). PMID- 29189893 TI - Maternal hemodynamics in late gestation and immediate postpartum in singletons vs. twin pregnancies. AB - PURPOSE: Differences in hemodynamic changes during a cesarean section (CS) between twin and singleton pregnancies are poorly defined. The Non-Invasive Cardiac System (NICaS) is an impedance device that measures cardiac output (CO) and its derivatives. We compared maternal cardiac parameters using NICaSTM in singleton and twins before and during delivery, as well at the early puerperium in healthy women undergoing CS at term. METHODS: This prospective longitudinal study included women with twin (n = 27) or singleton pregnancies (n = 62) whose hemodynamic parameters were assessed by NICaS before an elective CS, after spinal anesthesia, immediately after delivery, after fascia closure, and within 24-36 and 48-72 h postpartum. RESULTS: By 24-36 h postpartum, the mean arterial pressure and the total peripheral resistance equaled preoperative values in both groups. The CO increased throughout the CS and peaked immediately after delivery in the singleton group (P < 0.0001), after which it abruptly began to decline until reaching a nadir 24-36 h after delivery (P < 0.0001), while it remained steady throughout the CS and then dropped until 24-36 h after delivery in the twin group (P < 0.05). None of the studied parameters differed significantly between the groups for the 24-36 and 48-72 h postpartum measurements. CONCLUSIONS: Hemodynamic parameters immediately before, during and shortly after CS in singleton and twin pregnancies are equivalent. Further evaluations of the value of NICaSTM in assessing cardiovascular-related pregnancy complications are warranted. PMID- 29189895 TI - Acceptance and barriers to access of occupational e-mental health: cross sectional findings from a health-risk population of employees. AB - PURPOSE: Occupational e-mental-health (OEMH) may extend existing instruments for preservation or restoration of health and work ability. As a key precondition to efficient implementation, this study examined acceptance and person-centered barriers to potential uptake of OEMH for work-related distress in employees with an elevated risk of early retirement. METHODS: Within the framework of the "Third German Sociomedical Panel of Employees", 1829 employees with prior sickness absence payments filled out a self-administered questionnaire. Participants had a mean age of 49.93 years (SD = 4.06). 6.2% indicated prior use of eHealth interventions. Potential predictors of acceptance of OEMH were examined based on the "Unified Theory of Acceptance and Use of Technology" (UTAUT) extended by work ability, mental health, eHealth literacy and demographic characteristics. RESULTS: 89.1% (n = 1579) showed low to moderate acceptance (M = 2.20, SD = 1.05, range 1-5). A path analysis revealed significant, positive direct effects of UTAUT predictors on acceptance (performance expectancy: 0.48, SE = 0.02, p < 0.001; effort expectancy: 0.20, SE = 0.02, p < 0.001; social influence: 0.28, SE = 0.02, p < 0.001).Online time and frequency of online health information search were further positive direct predictors of acceptance. Model fit was good [chi 2(7) = 12.91, p = 0.07, RMSEA = 0.02, CFI = 1.00, TLI = 0.99, SRMR = 0.01]. CONCLUSIONS: Attitudes towards OEMH are rather disadvantageous in the studied risk group. Implementation of OEMH, therefore, requires a-priori education including promotion of awareness, favorable attitudes regarding efficacy and usability in a collaborative approach. PMID- 29189896 TI - Between a rux and a hard place: evaluating salvage treatment and outcomes in myelofibrosis after ruxolitinib discontinuation. AB - Ruxolitinib is a JAK1/2 inhibitor that is effective in managing symptoms and splenomegaly related to myelofibrosis (MF). Unfortunately, many patients must discontinue ruxolitinib, at which time treatment options are not well defined. In this study, we investigated salvage treatment options and clinical outcomes among MF patients who received and discontinued ruxolitinib outside the context of a clinical trial. Among 145 patients who received ruxolitinib, 23 died while on treatment, 58 remained on treatment at time of analysis, leaving 64 people available for analysis. Development of cytopenias was the most common reason for discontinuation (38%) after median treatment time of 3.8 months (mo). The majority of patients received some form of salvage therapy after ruxolitinib discontinuation (n = 42; 66%), with allogeneic hematopoietic stem cell transplant (alloHSCT) (n = 17), being most commonly employed. Lenalidomide, thalidomide, hydroxyurea, interferon, and danazol were used with similar frequency. The response rate to salvage treatment was 26% (8 responses) and responses were most often seen with lenalidomide or thalidomide. Improved outcomes were observed in patients who underwent alloHSCT or received salvage therapy compared to those who did not receive additional therapy. Median overall survival (OS) after ruxolitinib discontinuation was 13 months. These findings show that salvage therapy can provide clinical responses after ruxolitinib discontinuation; however, these responses are rare and outcomes in this patient population are poor. This represents an area of unmet clinical need in MF. PMID- 29189894 TI - The importance of an interaction network for proper DNA polymerase zeta heterotetramer activity. AB - Precisely controlled mechanisms have been evolved to rescue impeded DNA replication resulting from encountered obstacles and involve a set of low fidelity translesion synthesis (TLS) DNA polymerases. Studies in recent years have brought new insights into those TLS polymerases, especially concerning the structure and subunit composition of DNA polymerase zeta (Pol zeta). Pol zeta is predominantly involved in induced mutagenesis as well as the bypass of noncanonical DNA structures, and it is proficient in extending from terminal mismatched nucleotides incorporated by major replicative DNA polymerases. Two active forms of Pol zeta, heterodimeric (Pol zeta2) and heterotetrameric (Pol zeta4) ones, have been identified and studied. Here, in the light of recent publications regarding induced and spontaneous mutagenesis and diverse interactions within Pol zeta holoenzyme, combined with Pol zeta binding to the TLS polymerase Rev1p, we discuss the subunit composition of Pol zeta in various cellular physiological conditions. Available data show that it is the heterotetrameric form of Pol zeta that is involved both during spontaneous and induced mutagenesis, and underline the importance of interactions within Pol zeta when an increased Pol zeta recruitment occurs. Understanding Pol zeta function in the bypass of DNA obstacles would give a significant insight into cellular tolerance of DNA damage, genetic instability and the onset of cancer progression.

PMID- 29189898 TI - Immunogenicity of recombinant vaccinia virus vaccines co-expressing GP3/GP5 of European PRRSV and Cap protein of PCV2 in pigs. AB - Porcine reproductive and respiratory syndrome (PRRS) is almost always caused by the North American strain of PRRS virus (PRRSV) in China; the European genotype of PRRSV has emerged in China. The mixed infection of PRRSV and Porcine circovirus type 2 virus (PCV2) are always found in pigs and PRRSV-augmented PCV2 replication and serious clinical symptoms. Current vaccines cannot protect mixed European PRRSV and PCV2 infections. Therefore, the development of a safe and effective new vaccine to prevent and control the mixed infection of European PRRSV and PCV2 is both urgent and necessary. In this study, we developed a recombinant vaccinia vaccine co-expressing the GP3 and GP5 proteins of European PRRSV and the ORF2 protein of PCV2 and evaluated the immunogenicity and its protective effects and its inactivated vaccine in pigs. The recombinant vaccinia vaccine and its inactivated vaccine both elicited significant humoral and cellular immune responses with a higher level of specific antibody responses and T-lymphocyte proliferation than the control group. Furthermore, the pigs inoculated with the recombinant vaccinia vaccine were completely protected against challenge with 105 TCID50 of European PRRSV strain LV. These data suggest that the recombinant vaccinia vaccine is a potential candidate vaccine against European PRRSV and PCV2. PMID- 29189900 TI - Hygrocin C from marine-derived Streptomyces sp. SCSGAA 0027 inhibits biofilm formation in Bacillus amyloliquefaciens SCSGAB0082 isolated from South China Sea gorgonian. AB - Several ansamycins have been reported to inhibit bacterial biofilm formation and accelerate the eradication of developed biofilms, but little is known about the effect of hygrocin C, an ansamycin, on bacterial biofilm formation. Here, hygrocin C was isolated from the marine-derived Streptomyces sp. SCSGAA 0027 and reported for the first time to be capable of inhibiting the biofilm formation of Staphylococcus aureus and Bacillus amyloliquefaciens SCSGAB0082 with the production of anti-microbial lipopeptides from South China Sea gorgonian Subergorgia suberosa at concentrations of less than minimum inhibitory concentrations. Moreover, hygrocin C also promoted the eradication of developed biofilms, affected the biofilm architecture, and lowered the extracellular polymeric matrix formation, cell motility, and surface hydrophobicity in B. amyloliquefaciens, which was in accordance with the inhibition of biofilm formation. Furthermore, transcriptome analysis revealed that hygrocin C altered the transcripts of several genes associated with bacterial chemotaxis and flagellar, two-component system and the synthesis of arginine and histidine, which are important for bacterial biofilm formation. In conclusion, hygrocin C could be used as a potential biofilm inhibitor against S. aureus and B. amyloliquefaciens. But further genetic investigations are needed to provide more details for elucidation of the molecular mechanisms responsible for the effects of hygrocin C on B. amyloliquefaciens biofilm formation. PMID- 29189899 TI - Starter cultures as biocontrol strategy to prevent Brettanomyces bruxellensis proliferation in wine. AB - Brettanomyces bruxellensis is a common and significant wine spoilage microorganism. B. bruxellensis strains generally detain the molecular basis to produce compounds that are detrimental for the organoleptic quality of the wine, including some classes of volatile phenols that derive from the sequential bioconversion of specific hydroxycinnamic acids such as ferulate and p-coumarate. Although B. bruxellensis can be detected at any stage of the winemaking process, it is typically isolated at the end of the alcoholic fermentation (AF), before the staring of the spontaneous malolactic fermentation (MLF) or during barrel aging. For this reason, the endemic diffusion of B. bruxellensis leads to consistent economic losses in the wine industry. Considering the interest in reducing sulfur dioxide use during winemaking, in recent years, biological alternatives, such as the use of tailored selected yeast and bacterial strains inoculated to promote AF and MLF, are actively sought as biocontrol agents to avoid the "Bretta" character in wines. Here, we review the importance of dedicated characterization and selection of starter cultures for AF and MLF in wine, in order to reduce or prevent both growth of B. bruxellensis and its production of volatile phenols in the matrix. PMID- 29189901 TI - Elevational distribution and morphological attributes of the entomopathogenic fungi from forests of the Qinling Mountains in China. AB - Entomopathogenic fungi are considered to be a safe microbiological pesticide alternative to chemical control. Efforts are underway to understand precisely their taxonomy and natural distribution through mycological and biodiversity studies based on molecular markers. Here, we present descriptions of the diversity of the entomopathogenic fungi in the genera Metarhizium and Beauveria found along the elevational gradients of the Qinling subtropical and temperate forests of Shaanxi province in China, using morphological aspects and molecular markers. Molecular characterization using the Mz_IGS3 intergenic region revealed that Metarhizium isolates phylogenetically clustered in the PARB clade with four different distinguishable species, but the 5'-TEF gene allowed only ambiguous delimitation of Metarhizium species. Beauveria isolates were characterized by sequence analyses of the translation elongation factor 1-alpha and the Bloc region. The richness of Metarhizium species decreased with increasing elevation, with Metarhizium robertsii s.l. being the most abundant species along the elevational gradient. Our bioassay suggests that certain species of Metarhizium are significantly pathogenic to the insect model Tenebrio molitor at both the adult and larvae stages and could potentially serve as a control of insect pests of forests.

AB - Iron exopolysaccharide nanoparticles were biogenerated during ferric citrate fermentation by Klebsiella oxytoca DSM 29614. Before investigating their effects on Tuber borchii ("bianchetto" truffle) mycelium growth and morphology, they were tested on human K562 cell line and Lentinula edodes pure culture and shown to be non-toxic. Using these nanoparticles as iron supplement, the truffles showed extremely efficient iron uptake of over 300 times that of a commercial product. This avoided morphological changes in T. borchii due to lack of iron during growth and, with optimum nanoparticle dosage, increased growth without cell wall disruption or alteration of protoplasmatic hyphal content, the nuclei, mitochondria, and rough endoplasmic reticula being preserved. No significant modifications in gene expression were observed. These advantages derive from the completely different mechanism of iron delivery to mycelia compared to commercial iron supplements. The present data, in fact, show the nanoparticles attached to the cell wall, then penetrating it non-destructively without damage to cell membrane, mitochondria, chromatin, or ribosome. Low dosage significantly improved mycelium growth, without affecting hyphal morphology. Increases in hyphal diameter and septal distance indicated a healthier state of the mycelia compared to those grown in the absence of iron or with a commercial iron supplement. These positive effects were confirmed by measuring fungal biomass as mycelium dry weight, total protein, and ergosterol content. This "green" method for biogenerating iron exopolysaccharide nanoparticles offers many advantages, including significant economic savings, without toxic effects on the ectomycorrhizal fungus, opening the possibility of using them as iron supplements in truffle plantations. PMID- 29189903 TI - Comparison of food consumption and nutrient intake assessed with three dietary assessment methods: results of the German National Nutrition Survey II. AB - PURPOSE: Comparison of food consumption, nutrient intake and underreporting of diet history interviews, 24-h recalls and weighed food records to gain further insight into specific strength and limitations of each method and to support the choice of the adequate dietary assessment method. METHODS: For 677 participants (14-80 years) of the German National Nutrition Survey II confidence intervals for food consumption and nutrient intake were calculated on basis of bootstrapping samples, Cohen's d for the relevance of differences, and intraclass correlation coefficients for the degree of agreement of dietary assessment methods. Low energy reporters were identified with Goldberg cut-offs. RESULTS: In 7 of 18 food groups diet history interviews showed higher consumption means than 24-h recalls and weighed food records. Especially mean values of food groups perceived as socially desirable, such as fruit and vegetables, were highest for diet history interviews. For "raw" and "cooked vegetables", the diet history interviews showed a mean consumption of 144 and 109 g/day in comparison with 68 and 70 g/day in 24 h recalls and 76 and 75 g/day in weighed food records, respectively. For "fruit", diet history interviews showed a mean consumption of 256 g/day in comparison with 164 g/day in 24-h recalls and 147 g/day in weighed food records. No major differences regarding underreporting of energy intake were found between dietary assessment methods. CONCLUSIONS: With regard to estimating food consumption and nutrient intake, 24-h recalls and weighed food records showed smaller differences and better agreement than pairwise comparisons with diet history interviews. PMID- 29189904 TI - The association of whole and refined grains consumption with psychological disorders among Iranian adults. AB - PURPOSE: Although several studies have examined the link between different types of carbohydrate consumption and depression and anxiety, limited data are available linking whole and refined grains consumption to psychological disorders. We aimed to investigate the association of whole and refined grains consumption with psychological disorders among Iranian adults. METHODS: A total of 3172 adult people with age range of 18-55 years were included in this cross sectional study. Data on grains consumption were collected using a validated dish based 106-item semi-quantitative food frequency questionnaire. To assess depression and anxiety, Iranian validated version of Hospital Anxiety and Depression Scale (HADS) was applied. Furthermore, psychological distress was examined using General Health Questionnaire (GHQ). Psychological disorders were defined based on standard criteria. RESULTS: Mean age of participants was 36.5 +/ 7.9 years. Women in the third quartile of whole grains consumption had lower odds for having anxiety (OR 0.62, 95% CI 0.45-0.85) compared with those in the first quartile. This relationship was also seen even after controlling for potential confounders (OR 0.65, 95% CI 0.44-0.96). In contrast, compared with the first quartile, women in the highest quartile of refined grains consumption had greater odds to have depression (OR 1.76, 95% CI 1.00-3.09) and anxiety (OR 2.03, 95% CI 1.00-4.10) after adjusting for covariates. Such relationships were not observed among men. CONCLUSION: Moderate consumption of whole grain foods was inversely associated with anxiety in women, but not in men. Furthermore, we found a significant positive association between refined grains consumption, depression and anxiety in women. PMID- 29189906 TI - Individual variability in the structural properties of neurons in the human inferior olive. AB - The inferior olive (IO) is the sole source of the climbing fibers innervating the cerebellar cortex. We have previously shown both individual differences in the size and folding pattern of the principal nucleus (IOpr) in humans as well as in the expression of different proteins in IOpr neurons. This high degree of variability was not present in chimpanzee samples. The neurochemical differences might reflect static differences among individuals, but might also reflect age related processes resulting in alterations of protein synthesis. Several observations support the latter idea. First, accumulation of lipofuscin, the "age pigment" is well documented in IOpr neurons. Second, there are silver- and abnormal tau-immunostained intraneuronal granules in IOpr neurons (Ikeda et al. Neurosci Lett 258:113-116, 1998). Finally, Olszewski and Baxter (Cytoarchitecture of the human brain stem, Second edn. Karger, Basel, 1954) observed an apparent loss of IOpr neurons in older individuals. We have further investigated the possibility of age-related changes in IOpr neurons using silver- and immunostained sections. We found silver-labeled intraneuronal granules in neurons of the IOpr in all human cases studied (n = 17, ages 25-71). We did not, however, confirm immunostaining with antibodies to abnormal tau. There was individual variability in the density of neurons as well as in the expression of the calcium binding protein calretinin. In the chimpanzee, there were neither silver-stained intraneuronal granules nor irregularities in immunostaining. Overall, the data support the hypothesis that in some, but not all, humans there are functional changes in IOpr neurons and ultimately cell death. Neurochemical changes of IOpr neurons may contribute to age-related changes in motor and cognitive skills mediated by the cerebellum. PMID- 29189905 TI - Complementary research models and methods to study axonal regeneration in the vertebrate retinofugal system. AB - Due to the lack of axonal regeneration, age-related deterioration in the central nervous system (CNS) poses a significant burden on the wellbeing of a growing number of elderly. To overcome this regenerative failure and to improve the patient's life quality, the search for novel regenerative treatment strategies requires valuable (animal) models and techniques. As an extension of the CNS, the retinofugal system, consisting of retinal ganglion cells that send their axons along the optic nerve to the visual brain areas, has importantly contributed to the current knowledge on mechanisms underlying the restricted regenerative capacities and to the development of novel strategies to enhance axonal regeneration. It provides an extensively used research tool, not only in amniote vertebrates including rodents, but also in anamniote vertebrates, such as zebrafish. Indeed, the latter show robust regeneration capacities, thereby providing insights into the factors that contribute to axonal regrowth and proper guidance, complementing studies in mammals. This review provides an integrative and critical overview of the classical and state-of-the-art models and methods that have been employed in the retinofugal system to advance our knowledge on the signaling pathways underlying the restricted versus robust axonal regeneration in rodents and zebrafish, respectively. In vitro, ex vivo and in vivo models and techniques to improve the visualization and analysis of regenerating axons are summarized. As such, the retinofugal system is presented as a valuable model to further facilitate research on axonal regeneration and to open novel therapeutic avenues for CNS pathologies. PMID- 29189907 TI - Neural circuits underlying jaw movements for the prey-catching behavior in frog: distribution of vestibular afferent terminals on motoneurons supplying the jaw. AB - Coordinated movement of the jaw is essential for catching and swallowing the prey. The majority of the jaw muscles in frogs are supplied by the trigeminal motoneurons. We have previously described that the primary vestibular afferent fibers, conveying information about the movements of the head, established close appositions on the motoneurons of trigeminal nerve providing one of the morphological substrates of monosynaptic sensory modulation of prey-catching behavior in the frog. The aim of our study was to reveal the spatial distribution of vestibular close appositions on the somatodendritic compartments of the functionally different trigeminal motoneurons. In common water frogs, the vestibular and trigeminal nerves were simultaneously labeled with different fluorescent dyes and the possible direct contacts between vestibular afferents and trigeminal motoneurons were identified with the help of DSD2 attached to an Andor Zyla camera. In the rhombencephalon, an overlapping area was detected between the incoming vestibular afferents and trigeminal motoneurons along the whole extent of the trigeminal motor nucleus. The vestibular axon collaterals formed large numbers of close appositions with dorsomedial and ventrolateral dendrites of trigeminal motoneurons. The majority of direct contacts were located on proximal dendritic segments closer than 300 um to the somata. The identified contacts were evenly distributed on rostral motoneurons innervating jaw-closing muscles and motoneurons supplying jaw-opening muscles and located in the caudal part of trigeminal nucleus. We suggest that the identified contacts between vestibular axon terminals and trigeminal motoneurons may constitute one of the morphological substrates of a very quick response detected in trigeminal motoneurons during head movements. PMID- 29189908 TI - Diffusion tractography reveals pervasive asymmetry of cerebral white matter tracts in the bottlenose dolphin (Tursiops truncatus). AB - Brain enlargement is associated with concomitant growth of interneuronal distance, increased conduction time, and reduced neuronal interconnectivity. Recognition of these functional constraints led to the hypothesis that large brained mammals should exhibit greater structural and functional brain lateralization. As a taxon with the largest brains in the animal kingdom, Cetacea provides a unique opportunity to examine asymmetries of brain structure and function. In the present study, diffusion tensor imaging and tractography were used to investigate cerebral white matter asymmetry in the bottlenose dolphin (Tursiops truncatus). Widespread white matter asymmetries were observed with the preponderance of tracts exhibiting leftward structural asymmetries. Leftward lateralization may reflect differential processing and execution of behaviorally variant sensory and motor functions by the cerebral hemispheres. The arcuate fasciculus, an association tract linked to human language evolution, was isolated and exhibited rightward asymmetry suggesting a right hemisphere bias for conspecific communication unlike that of most mammals. This study represents the first examination of cetacean white matter asymmetry and constitutes an important step toward understanding potential drivers of structural asymmetry and its role in underpinning functional and behavioral lateralization in cetaceans. PMID- 29189910 TI - Bacterial colonisation of suture material after routine neurosurgical procedures: relevance for wound infection. AB - BACKGROUND: Wound healing impairment is a serious problem in surgical disciplines which may be associated with chronic morbidity, increased cost and patient discomfort. Here we aimed to investigate the relevance of bacterial colonisation on suture material using polymerase chain reaction (PCR) to detect and taxonomically classify bacterial DNA in patients with and without wound healing problems after routine neurosurgical procedures. METHODS: Repeat surgery was performed in 25 patients with wound healing impairment and in 38 patients with well-healed wounds. To determine the presence of bacteria, a 16S rDNA-based PCR detection method was applied. Fragments of 500 bp were amplified using universal primers which target hypervariable regions within the bacterial 16S rRNA gene. Amplicons were separated from each other by single-strand conformation polymorphism (SSCP) analysis, and finally classified using Sanger sequencing. RESULTS: PCR/SSCP detected DNA of various bacteria species on suture material in 10/38 patients with well-healed wounds and in 12/25 patients with wound healing impairment including Staphylococcus aureus, Staphylococcus epidermidis, Propionibacterium acnes and Escherichia coli. Microbiological cultures showed bacterial growth in almost all patients with wound healing impairment and positive results in PCR/SSCP (10/12), while this was the case in only one patient with a well-healed wound (1/10). CONCLUSIONS: Colonisation of suture material with bacteria occurs in a relevant portion of patients with and without wound healing impairment after routine neurosurgical procedures. Suture material may provide a nidus for bacteria and subsequent biofilm formation. Most likely, however, such colonisation of sutures is not a general primer for subsequent wound infection. PMID- 29189909 TI - Behavioral and physiological polymorphism in males of the austral lizard Liolaemus sarmientoi. AB - Integrative behavioral studies show that the interplay between individual physiology and social behavior influences the ecology of the species, ultimately affecting individual fitness. Particularly in lizards, color polymorphism is associated with differential behaviors and reproductive strategies, which are evident in mature males during the mating season. Dominant males generally have greater endurance, higher body temperature, and larger bodies than submissive males, so they can acquire and defend larger territories and have greater access to females for mating. We studied whether the color morphs observed in males of one of the world's southernmost reptiles, Liolaemus sarmientoi, are related to behavioral variation during agonistic interactions, thermal physiology, morphology, and/or locomotor stamina. Liolaemus sarmientoi males exhibit three color morphs: red (RR), red-yellow (RY), and yellow (YY). These lizards exhibit subtle behavioral displays and we did not observe stamina differences among morphs. However, we found that RR males are more aggressive than YY males during agonistic encounters. In addition, greater body temperature change during trials, higher field body temperatures, and greater head sizes of RR males compared to RY or YY indicate that RR is a dominant morph, which may influence their ability to acquire and defend territory and tactics for achieving reproductive success. PMID- 29189911 TI - Same, same but different!-matching entomological traces to a human food source by stable isotope analysis. AB - Blow flies are important tools in forensic entomology, as they feed and develop on human bodies. This fact can be used to estimate the minimum post mortem interval (PMImin), by classifying the age of the immature stages found on corpses. The capacity to also be able to classify the age of adult flies, or even empty puparia, could increase the timeframe for a PMImin. However, the association of older developmental stages, such as adult flies or their empty cases, with a human cadaver may be challenged, as such specimens could stem from another food source. Analyzing the stable carbon (delta13C) and nitrogen (delta15N) isotopes in such specimens could be helpful here, as the isotope signatures reflect those of the food sources. We compared the delta15N and delta13C signatures of tissue from humans and 12 additional species by elemental analyzer-isotope ratio mass spectrometry (EA-IRMS). We did the same for adult flies and empty puparia of the blow fly Lucilia sericata, which were derived from juvenile stages developed on tissues from the mentioned species. The isotope signatures for the adult flies and their empty puparia linearly mirrored the isotope signatures for the respective tissues on which they developed as larvae. Results such as these are useful to indicate the flies' nutritional history, but they do not provide the same kind of evidence that a DNA analysis would. As individual dietary habits, global distribution and environmental effects can influence isotope ratios, we strongly recommend to analyzing entomological traces and muscle tissues of potential donors or for other food sources. PMID- 29189912 TI - Cell wall biosynthesis impairment affects the budding lifespan of the Saccharomyces cerevisiae yeast. AB - The Saccharomyces cerevisiae yeast is one of the most widely used model in studies of cellular and organismal biology, including as aging and proliferation. Although several constraints of aging and budding lifespan have been identified, these processes have not yet been fully understood. Previous studies of aging in yeast have focused mostly on the molecular basics of the underlying mechanisms, while physical aspects, particularly those related to the cell wall, were rather neglected. In this paper, we examine for the first time, to our knowledge, the impact of cell wall biosynthesis disturbances on the lifespan in the budding yeast. We have used a set of cell wall mutants, including knr4Delta, cts1Delta, chs3Delta, fks1Delta and mnn9Delta, which affect biosynthesis of all major cell wall compounds. Our results indicated that impairment of chitin biosynthesis and cell wall protein mannosylation reduced the budding lifespan, while disruption in the 1,3-beta-glucan synthase activity had no adverse effect on that parameter. The impact varied in the severity and the most notable effect was observed for the mnn9Delta mutant. What was interesting, in the case of the dysfunction of the Knr4 protein playing the role of the transcriptional regulator of cell wall chitin and glucan synthesis, the lifespan increased significantly. We also report the phenotypic characteristics of cell wall-associated mutants as revealed by imaging of the cell wall using transmission electron microscopy, scanning electron microscopy and atomic force microscopy. In addition, our findings support the conviction that achievement of the state of hypertrophy may not be the only factor that determines the budding lifespan. PMID- 29189913 TI - Association between multimorbidity and mean platelet volume in diabetic patients with acute myocardial infarction. AB - AIMS: Diabetes mellitus (DM) is one of the most frequently detected conditions in multimorbid disease clusters. Platelet activation is one of the key mechanisms underlying atherothrombosis in acute myocardial infarction. Available data link mean platelet volume (MPV) to poor prognosis not only in cardiovascular and non cardiovascular disease. Given the lack of research data on the association between disease clusters and MPV, we have set out to investigate the link between multimorbidity and MPV in diabetic patients with acute myocardial infarction. METHODS: A total of 277 patients with DM and STEMI undergoing primary percutaneous coronary intervention were enrolled. Based on the number of comorbidities the study population was divided into two groups: group 1 (N = 58) with <= 1 comorbidity and group 2 (N = 219) with >= 2 comorbidities. A subanalysis was performed within the multimorbidity group: group 2A with two or three comorbidities (N = 156) and group 2B with at least four comorbidities (N = 63). RESULTS: In the study population, 15.9% of patients had one comorbidity, and 22.0, 34.3, and 22.7% of patients had two, three, or at least four comorbid conditions, respectively. Both MPV and PDW were elevated in multimorbid patients (9.3 vs 10.8 fl and 9.5 vs 10.3 fl, respectively). The highest platelet volume indices were observed in patients with at least four comorbid conditions. There was a moderate positive correlation between MPV and the total number of comorbidities, the number of CVD comorbidities, and the number of non-CVD comorbidities. CONCLUSIONS: These findings indicate that multimorbidity is associated with an increase in platelet volume indices. MPV values increased with the increasing number of comorbid conditions. Importantly, MPV values were elevated in some, but not all CVD and non-CVD conditions.

AB - PURPOSE: The mechanism of action of CNDAC (2'-C-cyano-2'-deoxy-1-beta-D-arabino pentofuranosyl-cytosine) is unique among deoxycytidine analogs because upon incorporation into DNA it causes a single strand break which is converted to a double strand break after DNA replication. This lesion requires homologous recombination (HR) for repair. CNDAC, as the parent nucleoside, DFP10917, and as an oral prodrug, sapacitabine, are undergoing clinical trials for hematological malignancies and solid tumors. The purpose of this study is to investigate the potential of CNDAC for the therapy of ovarian cancer (OC). METHODS: Drug sensitivity was evaluated using a clonogenic survival assay. Drug combination effects were quantified by median effect analysis. RESULTS: OC cells lacking function of the key HR genes, BRCA1 or BRCA2, were more sensitive to CNDAC than corresponding HR proficient cells. The sensitization was associated with greater levels of DNA damage in response to CNDAC at clinically achievable concentrations, manifested as chromosomal aberrations. Three classes of CNDAC based drug combinations were investigated. First, the PARP1 inhibitors, rucaparib and talazoparib, were selectively synergistic with CNDAC in BRCA1/2 deficient OC cells (combination index < 1) at a relatively low concentration range. Second, cisplatin and oxaliplatin had additive combination effects with CNDAC (combination index ~ 1). Finally, paclitaxel and docetaxel achieved additive cell killing effects with CNDAC at concentration ranges of the taxanes similar for both BRCA1/2 deficient and proficient OC cells. CONCLUSIONS: This study provides mechanistic rationales for combining CNDAC with PARP inhibitors, platinum compounds and taxanes in ovarian cancer lacking BRCA1/2 function. PMID- 29189916 TI - Improving Efficiency and Quality of the Children's ASD Diagnostic Pathway: Lessons Learned from Practice. AB - The 'autism diagnosis crisis' and long waiting times for assessment are as yet unresolved, leading to undue stress and limiting access to effective support. There is therefore a significant need for evidence to support practitioners in the development of efficient services, delivering acceptable waiting times and effectively meeting guideline standards. This study reports statistically significant reductions in waiting times for autism diagnostic assessment following a children's health service improvement programme. The average wait between referral and first appointment reduced from 14.2 to 10.4 weeks (t(21) = 4.3, p < 0.05) and between referral and diagnosis shared, reduced from 270 to 122.5 days, (t(20) = 5.5, p < 0.05). The proportion of girls identified increased from 5.6 to 2.7:1. Methods reported include: local improvement action planning; evidence based pathways; systematic clinical data gathering and a training plan. This is a highly significant finding for many health services wrestling with the challenges of demand and capacity for autism diagnosis and assessment. PMID- 29189917 TI - The Glasgow Sensory Questionnaire: Validation of a French Language Version and Refinement of Sensory Profiles of People with High Autism-Spectrum Quotient. AB - Sensory sensitivity peculiarities represent an important characteristic of Autism Spectrum Disorders (ASD). We first validated a French language version of the Glasgow Sensory Questionnaire (GSQ) (Robertson and Simmons in J Autism Dev Disord 43(4):775-784, 2013). The GSQ score was strongly positively correlated with the Autism-Spectrum Quotient (AQ) (r = 0.81, p < 10-6, n = 245). We further examined sensory profiles of groups with high versus low AQ. The high AQ group scored higher at the GSQ than the low AQ group for every sensory modality. Moreover, the high AQ group showed greater consistency in their patterns of hypersensitivity and hyposensitivity between sensory modalities, and stronger correlations between hyper and hyposensitivity. Results are discussed in the context of theories accounting for atypical sensory perception in ASD. PMID- 29189918 TI - Predictors of Satisfaction with Life in Parents of Children with Autism Spectrum Disorder. AB - This study examined the relationships between autism spectrum disorder (ASD) symptoms, care-related activities, and satisfaction with life (SWL) in 184 parents caring for a child with ASD in New Zealand. The relationships between coping styles and SWL were also examined. The parents' SWL scores indicated they were slightly dissatisfied with their lives. A stepwise linear regression showed three predictors (care-related health problems, carer esteem and financial difficulties) explained 47% of the variance in SWL scores. Several coping styles were associated with lowered SWL, and only emotional support was related to increased SWL. The regression model provides a focus for monitoring parental wellbeing, and stresses the importance of recognition and support for the substantial responsibilities parents of children with ASD face. PMID- 29189920 TI - Politicians lie, so do I. AB - This research analyzed whether political leaders make people lie via priming experiments. Priming is a non-conscious and implicit memory effect in which exposure to one stimulus affects the response to another. Following priming theories, we proposed an innovative concept that people who perceive leaders to be dishonest (such as liars) are likely to lie themselves. We designed three experiments to analyze and critically discussed the potential influence of prime effect on lying behavior, through the prime effect of French political leaders (including general politicians, presidents and parties). Experiment 1 discovered that participants with non-politician-prime were less likely to lie (compared to politician-prime). Experiment 2A discovered that, compared to Hollande-prime, Sarkozy-prime led to lying behavior both in gravity (i.e., bigger lies) and frequency (i.e., lying more frequently). Experiment 2B discovered that Republicans-prime yielded an impact on more lying behavior, and Sarkozy-prime made such impact even stronger. Overall, the research findings suggest that lying can be triggered by external influencers such as leaders, presidents and politicians in the organizations. Our findings have provided valuable insights into organizational leaders and managers in their personnel management practice, especially in the intervention of lying behavior. Our findings also have offered new insights to explain non-conscious lying behavior. PMID- 29189919 TI - Autistic Symptoms in Children and Adolescents with Gender Dysphoria. AB - Studies have shown an increase of symptoms of autism spectrum disorder (ASD) in gender dysphoria (GD). Various hypotheses try to explain this possible co occurrence (e.g., a role of resistance to change, stereotyped behaviors or prenatal testosterone exposure). This study examined ASD symptoms with the Children's Social Behavior Questionnaire (CSBQ) in 490 children with GD compared to 2507 typically developing (TD) and 196 children with ASD. CSBQ total scores of the GD sample were in between scores from the TD and ASD sample. The GD sample showed elevated levels of autistic symptomatology on all subdomains, not only on stereotyped and resistance to change. Further, no gender differences and interaction effects were found on the total CSBQ, making a sole role for prenatal testosterone unlikely. PMID- 29189921 TI - Lithium Toxicity in Older Adults: a Systematic Review of Case Reports. AB - BACKGROUND AND OBJECTIVES: Despite concerns regarding the vulnerability of older adults to lithium toxicity, this has not been well studied. This literature review aims to characterize the nature of lithium toxicity in older adults, the doses and serum lithium levels associated with toxicity, as well as its clinical and laboratory manifestations, precipitating factors, management and outcome. METHODS: A systematic 10-year search of English articles was conducted using Ovid Medline, Embase Classic + Embase, Cochrane Central Register of Controlled Trials and PsycINFO. All studies on lithium toxicity in elderly (aged >= 65 years) where the dose of lithium or serum lithium level was clearly described, were included. RESULTS: There were no clinical trials or cohort studies found. The search identified 38 cases of lithium toxicity in older adults with a mean age of 71.4 years (SD = 5.53). Mean dose of lithium was 675.4 mg/d (SD = 200.66), and mean toxic serum concentration was 2.55 mmol/L (SD = 2.22). Manifestations varied, with neurotoxicity being the most common, followed by renal and cardiovascular toxicity. Polypharmacy (63.2%) and medical comorbidity (76.3%) were common. Intravenous hydration and hemodialysis were widely used for treatment with good effect. Most patients recovered fully, and only one patient died despite treatment. CONCLUSION: In published case reports, the lithium dose was higher than recommended for older adults. Polypharmacy and comorbidities appeared to be important precipitating factors of lithium toxicity. Regular monitoring of serum lithium concentrations and appropriate caution should be exercised, even when serum lithium concentrations are within reported therapeutic levels. PMID- 29189922 TI - Apathy and its impact on patient outcome in amyotrophic lateral sclerosis. AB - Apathy is one of the most common behavioural symptoms of amyotrophic lateral sclerosis (ALS), yet there are few studies that have investigated the relationship between apathy and quality of life (QOL) as they are experienced by the patient. A cohort of 60 ALS patients were evaluated using the Apathy Evaluation Scale which measured cognitive, behavioural, emotional and non specific symptoms of apathy combined with the Personal Wellbeing Index, a multidimensional measure of QOL. The relationship between patient-rated apathy and QOL scores, controlling for potential clinical and psychological confounders were analysed using univariate and multivariate methods. Apathy was identified in 30% of ALS patients. Patients with apathy reported higher levels of depression (p = 0.0001). Compared to non-apathetic patients, patients with apathy had lower overall QOL (p = 0.001), most pronounced in the domains related to achievements in life (p = 0.001) and community-connectedness (p = 0.0001). Of the cognitive, behavioural, emotional and non-specific manifestations of apathy, only the emotional symptoms explained a significant amount of variance in achievements in life (p = 0.003) and community-connectedness (p = 0.001). As such, emotional manifestations of apathy may underlie worse QOL in ALS patients presenting with behavioural impairment. Patient-reported outcomes, particularly those assessing psychosocial functioning may be important for demonstrating the efficacy of interventions designed to improve QOL in ALS patients with behavioural impairment. PMID- 29189924 TI - Immobilization in polyvinyl alcohol hydrogel enhances yeast storage stability and reusability of recombinant laccase-producing S. cerevisiae. AB - OBJECTIVES: To improve the storage stability and reusability of various yeast strains and species by immobilization in polyvinyl alcohol (PVA) hydrogel particles. RESULTS: Debaryomyces hansenii, Pichia sorbitophila, Saccharomyces cerevisiae, Yarrowia lipolytica, and Zygosaccharomyces rouxii were immobilized in PVA particles using LentiKats technology and stored in sterile water at 4 degrees C. The immobilization improved the survival of all species; however, the highest storage stability was achieved for S. cerevisiae and Y. lipolytica which survived more than 1 year, in contrast to free cells that survived for only 3 months. Tests of the reusability of immobilized recombinant laccase-secreting S. cerevisiae revealed that the cells were suitable for repetitive use (55 cycles during 15 months) even after storage in water at 4 degrees C for 9 months. A suitable method for killing immobilized laccase-secreting cells without affecting the produced enzyme activity was also developed. CONCLUSIONS: The immobilization of yeasts in PVA hydrogel enables long-term, cheap storage with very good cell viability and productivity, thus becoming a promising approach for industrial applications. PMID- 29189923 TI - Congenital myasthenic syndrome with episodic apnoea: clinical, neurophysiological and genetic features in the long-term follow-up of 19 patients. AB - BACKGROUND: Congenital myasthenic syndrome with episodic apnoea (CMS-EA) is a rare but potentially treatable cause of apparent life-threatening events in infancy. The underlying mechanisms for sudden and recurrent episodes of respiratory arrest in these patients are unclear. Whilst CMS-EA is most commonly caused by mutations in CHAT, the list of associated genotypes is expanding. METHODS: We reviewed clinical information from 19 patients with CMS-EA, including patients with mutations in CHAT, SLC5A7 and RAPSN, and patients lacking a genetic diagnosis. RESULTS: Lack of genetic diagnosis was more common in CMS-EA than in CMS without EA (56% n = 18, compared to 7% n = 97). Most patients manifested intermittent apnoea in the first 4 months of life (74%, n = 14). A degree of clinical improvement with medication was observed in most patients (74%, n = 14), but the majority of cases also showed a tendency towards complete remission of apnoeic events with age (mean age of resolution 2 years 5 months). Signs of impaired neuromuscular transmission were detected on neurophysiology studies in 79% (n = 15) of cases, but in six cases, this was only apparent following specific neurophysiological testing protocols (prolonged high-frequency stimulation). CONCLUSIONS: A relatively large proportion of CMS-EA remains genetically undiagnosed, which suggests the existence of novel causative CMS genes which remain uncharacterised. In light of the potential for recurrent life threatening apnoeas in early life and the positive response to therapy, early diagnostic consideration of CMS-EA is critical, but without specific neurophysiology tests, it may go overlooked.

AB - OBJECTIVES: To investigate the potential role and underlying mechanism of Sirtuin2 (SIRT2) in regulating high glucose (HG)-induced vascular endothelial cell injury by using human umbilical vein endothelial cells (HUVECs). RESULTS: SIRT2 mRNA and protein expression levels were decreased in HG-treated HUVECs. SIRT2 overexpression increased viability, decreased apoptosis and reduced levels of reactive oxygen species in HG-treated HUVECs. SIRT2 overexpression decreased TNF-alpha expression (146.5 +/- 22.8 pg TNF-alpha ml-1) relative to that in the empty vector group (263.5 +/- 18.5 pg TNF-alpha ml-1) and decreased MCP-1 expression (63.8 +/- 9.85 pg MCP-1 ml-1) relative to that in the empty vector group (105.8 +/- 8.5 pg MCP-1 ml-1). SIRT2 overexpression decreased the acetylation of p53 by 33% and decreased the acetylation of NF-kappaB p65 by 58% in HG-treated HUVECs. CONCLUSION: SIRT2 prevents HG-induced vascular endothelial cell injury through suppressing the p53 and NF-kappaB signaling pathways.

AB - OBJECTIVES: To prove the possibility of efficient starch photofermentation in co culture of heterotrophic and phototrophic bacteria over prolonged period. RESULTS: Repeated batch photofermentation of starch was demonstrated in co culture Clostridium butyricum and Rhodobacter sphaeroides under microaerobic conditions. It continued 15 months without addition of new inoculum or pH regulation when using 4-5 g starch l-1 and 0.04 g yeast extract l-1. The complete degradation of starch without volatile fatty acids accumulation was shown in this co-culture. The average H2 yield of 5.2 mol/mol glucose was much higher than that in Clostridium monoculture. The species composition of co-culture was studied by q-PCR assay. The concentration of Clostridium cells in prolonged co-culture was lower than in monoculture and even in a single batch co-culture. This means that Clostridia growth was significantly limited whereas starch hydrolysis still took place. CONCLUSION: The prolonged repeated batch photofermentation of starch by co culture C. butyricum and R. sphaeroides provided efficient H2 production without accumulation of organic acids under conditions of Clostridia limitation.

AB - Protein structure determination using NMR is dependent on experimentally acquired distance restraints. Often, however, an insufficient number of these restraints are available for determining a protein's correct fold, much less its detailed three-dimensional structure. In consideration of this problem, we propose a simple means to acquire supplemental structural restraints from protein surface accessibilities using solvent saturation transfer to proteins (SSTP), based on the principles of paramagnetic chemical-exchange saturation transfer. Here, we demonstrate the utility of SSTP in structure calculations of two proteins, TSG101 and ubiquitin. The observed SSTP was found to be directly proportional to solvent accessibility. Since SSTP does not involve the direct excitation of water, which compromises the analysis of protein protons entangled in the breadth of the water resonance, it has an advantage over conventional water-based magnetization transfers. Inclusion of structural restraints derived from SSTP improved both the precision and accuracy of the final protein structures in comparison to those determined by traditional approaches, when using minimal amounts of additional structural data. Furthermore, we show that SSTP can detect weak protein-protein interactions which are unobservable by chemical shift perturbations.

PMID- 29189928 TI - Sedentary Behavior and Body Weight and Composition in Adults: A Systematic Review and Meta-analysis of Prospective Studies. AB - BACKGROUND: The cumulative effect of too much sedentary behavior may contribute to weight gain and obesity. OBJECTIVE: The aim of this study was to conduct a systematic review and meta-analysis of prospective cohorts and randomized controlled studies to determine the association between sedentary behavior and body weight and obesity in adults. DATA SOURCES AND STUDY SELECTION: Relevant studies were identified from searches of the MEDLINE, Embase, AMED and PubMed databases up to May 2017, and by manual searches of in-text citations. Studies that evaluated the association in adults between sedentary behavior and body weight or obesity, while controlling for physical activity, were included. Overall, 31 publications met the eligibility criteria, including 23 prospective cohort studies with data that could be extracted for a quantitative meta analysis, and a single randomized controlled trial. RESULTS: There were no significant associations between sedentary behavior and any measure of body weight or obesity, with the exception of waist circumference. For the latter outcome, over a 5-year follow-up period, each 1 h per day increase-from baseline to follow-up-in sedentary behavior was associated with a 0.02 mm [95% confidence interval (CI) 0.01-0.04; p = 0.001) increase in waist circumference. The odds ratio of becoming overweight or obese was 1.33 (95% CI 1.11-1.60; p = 0.001) in the highest compared with lowest categories of sedentary behavior. CONCLUSIONS: Meta-analysis of data from prospective cohort studies showed small, inconsistent and non-significant associations between sedentary behavior and body weight. PMID- 29189930 TI - Periodization Theory: Confronting an Inconvenient Truth. AB - Periodization theory has, over the past seven decades, emerged as the preeminent training planning paradigm. The philosophical underpinnings of periodization theory can be traced back to the integration of diverse shaping influences, whereby coaching beliefs and traditions were blended with historically available scientific insights and contextualized against pervading social planning models. Since then, many dimensions of elite preparation have evolved significantly, as driven by a combination of coaching innovations and science-led advances in training theory, techniques, and technologies. These advances have been incorporated into the fabric of the pre-existing periodization planning framework, yet the philosophical assumptions underpinning periodization remain largely unchallenged and unchanged. One particularly influential academic sphere of study, the science of stress, particularly the work of Hans Selye, is repeatedly cited by theorists as a central pillar upon which periodization theory is founded. A fundamental assumption emanating from the early stress research is that physical stress is primarily a biologically mediated phenomenon: a presumption translated to athletic performance contexts as evidence that mechanical training stress directly regulates the magnitude of subsequent 'fitness' adaptations. Interestingly, however, since periodization theory first emerged, the science of stress has evolved extensively from its historical roots. This raises a fundamental question: if the original scientific platform upon which periodization theory was founded has disintegrated, should we critically re evaluate conventional perspectives through an updated conceptual lens? Realigning periodization philosophy with contemporary stress theory thus presents us with an opportunity to recalibrate training planning models with both contemporary scientific insight and progressive coaching practice. PMID- 29189931 TI - Preoperative sentinel lymph node localization in vulvar cancer: preliminary experience with inguinal intradermal contrast-enhanced ultrasound. AB - OBJECTIVE: To evaluate the feasibility and diagnostic performance of intradermal contrast-enhanced ultrasound (CEUS) sentinel lymph node (SLN) procedure in vulvar cancer. METHODS: Twelve consecutive patients with vulvar cancer underwent preoperatively inguinal CEUS SLN examination and guide wire marking of the enhanced lymph nodes. Altogether, 20 groins were examined with CEUS contrast agent injections including 8 bilateral groins due to midline tumours. One groin was excluded due to previous inguinal surgery. The results of the CEUS examinations were compared to conventional SLN biopsy using radiocolloid scintigraphy and/or methylene blue dye and final postoperative histopathology. RESULTS: The inguinal sentinel CEUS procedure had a technical success rate of 94.7% (18/19 injections) for identifying a potential inguinal SLN. Conventional SLN biopsy using lymphoscintigraphy and/or methylene blue dye was successfully performed in 16 groins. Compared to conventional SLN biopsy, the overall sensitivity was 81.2% (13/16 injections). Additionally, CEUS detected enhancing SLNs in two cases when traditional SLN procedure failed to do so. All metastatic SLNs (n = 5) were correctly identified by CEUS procedure. CONCLUSIONS: Intradermal CEUS SLN localization can be applied in the inguinal lymphatic region in patients with vulvar cancer. Further studies are needed to verify the clinical value of this method. KEY POINTS: * CEUS is a feasible method for inguinal SLN detection in vulvar cancer * All metastatic inguinal SLNs were identified by CEUS procedure * Further studies are needed to verify the clinical value of this method. PMID- 29189932 TI - Contrast-enhanced US for characterization of focal liver lesions: a comprehensive meta-analysis. AB - OBJECTIVES: This meta-analysis was performed to evaluate the accuracy of contrast enhanced ultrasound (CEUS) in differentiating malignant from benign focal liver lesions (FLLs). METHODS: Cochrane Library, PubMed and Web of Science databases were systematically searched and checked for studies using CEUS in characterization of FLLs. Data necessary to construct 2*2 contingency tables were extracted from included studies. The QUADAS tool was utilized to assess the methodologic quality of the studies. Meta-analysis included data pooling, subgroup analyses, meta-regression and investigation of publication bias was comprehensively performed. RESULTS: Fifty-seven studies were included in this meta-analysis and the overall diagnostic accuracy in characterization of FLLs was as follows: pooled sensitivity, 0.92 (95%CI: 0.91-0.93); pooled specificity, 0.87 (95%CI: 0.86-0.88); diagnostic odds ratio, 104.20 (95%CI: 70.42-154.16). Subgroup analysis indicated higher diagnostic accuracy of the second-generation contrast agents (CAs) than the first-generation CA (Levovist; DOR: 118.27 vs. 62.78). Furthermore, Sonazoid demonstrated the highest diagnostic accuracy among three major CAs (SonoVue, Levovist and Sonazoid; DOR: 118.82 vs. 62.78 vs. 227.39). No potential publication bias was observed of the included studies. CONCLUSION: CEUS is an accurate tool to stratify the risk of malignancy in FLLs. The second generation CAs, especially Sonazoid may greatly improve diagnostic performance. KEY POINTS: * CEUS shows excellent diagnostic accuracy in differentiating malignant from benign FLLs. * The second-generation CAs have higher diagnostic accuracy than first-generation CAs. * Sonazoid demonstrates the highest diagnostic accuracy among three major CAs. PMID- 29189933 TI - Cardiac structure and function in elite Native Hawaiian and Pacific Islander Rugby Football League athletes: an exploratory study. AB - The aim of this exploratory study was to define the Athletes Heart (AH) phenotype in Native Hawaiian & Pacific Islander (NH&PI) Rugby Football League (RFL) athletes. Specifically, (1) to describe conventional echocardiographic indices of left ventricle (LV) and right ventricle (RV) structure and function in NH&PI RFL players and matched RFL Caucasian controls (CC) and (2) to demonstrate LV and RV mechanics in these populations. Ethnicity is a contributory factor to the phenotypical expression of the AH. There are no data describing the cardiac phenotype in NH&PI athletes. Twenty-one male elite NH&PI RFL athletes were evaluated using conventional echocardiography and myocardial speckle tracking, allowing the assessment of global longitudinal strain (epsilon) and strain rate (SR); and basal, mid and global radial and circumferential epsilon and SR. Basal and apical rotation and twist were also assessed. Results were compared with age matched Caucasian counterparts (CC; n = 21). LV mass [42 +/- 9 versus 37 +/- 4 g/(m2.7)], mean LV wall thickness (MWT: 9.5 +/- 0.7 and 8.7 +/- 0.4 mm), relative wall thickness (RWT: 0.35 +/- 0.04 and 0.31 +/- 0.03) and RV wall thickness (5 +/ 1 and 4 +/- 1 mm, all p < 0.05) were greater in NH&PI compared with CC. LV and RV cavity dimensions and standard indices of LV and RV systolic and diastolic function were similar between groups. NH&PI demonstrated reduced peak LV mid circumferential epsilon and early diastolic SR, as well as reduced global radial epsilon. There was reduced basal rotation at 25-35% systole, reduced apical rotation at 25-40% and 60-100% systole and reduced twist at 85-95% systole in NH&PI athletes. There were no differences between the two groups in RV wall mechanics. When compared to Caucasian controls, NH&PI rugby players have a greater LV mass, MWT and RWT with concomitant reductions in circumferential and twist mechanics. This data acts to prompt further research in NH&PI athletes. PMID- 29189934 TI - Mechanical deformation in adult patients with unrepaired aortic coarctation. AB - Aortic coarctation is a congenital heart disease that causes an increased left ventricular afterload, resulting in increased systolic parietal tension, compensatory hypertrophy, and left ventricular systolic and diastolic dysfunction. The speckle tracking is a new echocardiographic technique that allows the detection of subclinic left ventricular systolic dysfunction. The aim of this study was to detect early left ventricular dysfunction using mechanical deformation by echocardiography in adults with un-repaired aortic coarctation. A total of 41 subjects were studied, 20 patients with aortic coarctation and 21 control subjects, 21 women (51.2%), with an average age of 30 +/- 10 years. All patients with aortic coarctation had systemic arterial hypertension (p < 0.001). Seventy percent (14/20) of the patients had bicuspid aortic valve. Statistically significance (p < 0.005) were found in left ventricular mass index, E/e ratio, pulmonary artery systolic pressure and peak velocity and maximum gradient of the aortic valve. The global longitudinal deformation of the left ventricle in patients with aortic coarctation was significative decreased, p < 0.001. The ejection fraction and the global longitudinal deformation of the left ventricle were significantly lower in patients with aortic coarctation compared to the control group, p < 0.003, p < 0.001, respectively. The subgroup of patients with coarctation and left ventricular ejection fraction < 55% had a marked decrease in global longitudinal strain (- 15.9 +/- 4%). The radial deformation was increased in patients with aortic coarctation and showed a trend to be significant (r = 0.421; p < 0.06). A significant negative correlation was observed between the global longitudinal deformation and left ventricular mass index (r = 0.54; p = 0.01) in the aortic coarctation group. The patients with aortic coarctation and left ventricular hypertrophy had marked reduction of left ventricular global longitudinal deformation (- 16%, p < 0.05). In our study patients with normal left ventricular ejection fraction had abnormal global longitudinal deformation and also the increased left ventricular mass was related with a decreased left ventricular global longitudinal deformation as a sign of subclinical systolic dysfunction. PMID- 29189935 TI - The physiology of the Tambaqui (Colossoma macropomum) at pH 8.0. AB - The Tambaqui is a model neotropical teleost which is of great economic and cultural importance in artisanal fisheries and commercial aquaculture. It thrives in ion-poor, often acidic Amazonian waters and exhibits excellent regulation of physiology down to water pH 4.0. Curiously, however, it is reported to perform poorly in aquaculture at pH 8.0, an only slightly alkaline pH which would be benign for most freshwater fish. In initial experiments with Tambaqui of intermediate size (30-50 g), we found that ammonia excretion rate was unchanged at pH 4, 5, 6, and 7, but elevated after 20-24 h at pH 8, exactly opposite the pattern seen in most teleosts. Subsequent experiments with large Tambaqui (150 300 g) demonstrated that only ammonia, and not urea excretion was increased at pH 8.0, and that the elevation was proportional to a general increase in MO2. There was an accompanying elevation in net acidic equivalent excretion and/or basic equivalent uptake which occurred mainly at the gills. Net Na+ balance was little affected while Cl- balance became negative, implicating a disturbance of Cl- versus base exchange rather than Na+ versus acid exchange. Arterial blood pH increased by 0.2 units at pH 8.0, reflecting combined metabolic and respiratory alkaloses. Most parameters recovered to control levels by 18-24 h after return to pH 6.0. With respect to large Tambaqui, we conclude that a physiology adapted to acidic pH performs inappropriately at moderately alkaline pH. In small Tambaqui (4-15 g), the responses were very different, with an initial inhibition of ammonia excretion rate at pH 8.0 followed by a subsequent restoration of control levels. Elevated ammonia excretion rate occurred only after return to pH 6.0. Furthermore, MO2, plasma cortisol, and branchial vH+ATPase activities all declined during pH 8.0 exposure in small Tambaqui, in contrast to the responses in larger fish. Overall, small Tambaqui appear to cope better at pH 8.0, a difference that may correlate with their natural history in the wild. PMID- 29189936 TI - P2Y14 receptor activation decreases interleukin-6 production and glioma GL261 cell proliferation in microglial transwell cultures. AB - Gliomas are rich in extracellular nucleotides that modulate glioma cell production of multiple cytokines including interleukin (IL)-6, which strongly contributes to glioma cell proliferation. However, little is known about how nucleotide signaling modulates microglial/macrophage (MG/MP) cytokine production in the context of gliomas, nor how MG/MP purinergic P2 receptor expression changes in the tumor micro-environment. We hypothesized that: (1) expression of key P2Y receptors will be augmented in glioma-derived MG/MP, and (2) selective activation of these receptors in vitro will regulate microglial production of IL 6 and glioma cell proliferation. We tested these hypotheses using the murine GL261 glioma model. Compared to MG/MP isolated from the normal brain tissue, CD11b+ cells isolated from GL261 tumors expressed higher levels of several P2 receptors, including P2Y14 receptors. To evaluate microglial P2Y14 receptor function in the context of tumor cells, we first cultured N9 microglia in transwells with GL261 cells and found that microglial P2Y14 mRNA levels were similarly increased in transwell cultures. GL261 cells did not express detectable P2Y14 levels either when they were cultured alone or in transwell cultures with N9 cells. Selective P2Y14 receptor activation with UDP-glucose (UDPG) did not affect IL-6 levels in either cell type cultured alone, but in transwell cultures, UDPG decreased IL-6 protein levels in the medium. Application of conditioned medium from UDPG-treated microglia reduced GL261 cell proliferation. Together, these data suggest that P2Y14 receptors may be a key a receptor involved in glioma cell-MG/MP communication in the tumor environment. PMID- 29189937 TI - Bioactive focus in conformational ensembles: a pluralistic approach. AB - Computational generation of conformational ensembles is key to contemporary drug design. Selecting the members of the ensemble that will approximate the conformation most likely to bind to a desired target (the bioactive conformation) is difficult, given that the potential energy usually used to generate and rank the ensemble is a notoriously poor discriminator between bioactive and non bioactive conformations. In this study an approach to generating a focused ensemble is proposed in which each conformation is assigned multiple rankings based not just on potential energy but also on solvation energy, hydrophobic or hydrophilic interaction energy, radius of gyration, and on a statistical potential derived from Cambridge Structural Database data. The best ranked structures derived from each system are then assembled into a new ensemble that is shown to be better focused on bioactive conformations. This pluralistic approach is tested on ensembles generated by the Molecular Operating Environment's Low Mode Molecular Dynamics module, and by the Cambridge Crystallographic Data Centre's conformation generator software. PMID- 29189939 TI - Successional convergence in experimentally disturbed intertidal communities. AB - Determining the causes of variation in community assembly is a central question in ecology. Analysis of beta-diversity can provide insight by relating the extent of regional to local variation in diversity, allowing inference of the relative importance of deterministic versus stochastic processes. We investigated the effects of disturbance timing on community assembly at three distinct regions with varying environmental conditions: Northern Portugal, Azores and Canaries. On the lower rocky intertidal, quadrats were experimentally cleared of biota at three distinct times of the year and community assembly followed for 1 year. Similar levels of alpha- and gamma-diversity were found in all regions, which remained constant throughout succession. When Jaccard (incidence-based) and Bray Curtis (abundance-based) metrics were used, beta-diversity (the mean dissimilarity among plots cleared at the different times) was larger during early stages of community assembly but decreased over time. The adaptation of the Raup Crick's metric, which accounts for changes in species richness, showed that the structure of assemblages disturbed at different times of the year was similar to the null model of random community assembly during early stages of succession but became more similar than expected by chance. This pattern was observed in all regions despite differences in the regional species pool, suggesting that priority effects are likely weak and deterministic processes determine community structure despite stochasticity during early stages of community assembly. PMID- 29189938 TI - Trans-generational but not early life exposure to stressors influences offspring morphology and survival. AB - Environmental changes, such as the introduction of non-native species, can impose novel selective pressures. This can result in changes in fitness-relevant traits within an individual's lifetime or across multiple generations. We investigated the effects of early life versus trans-generational exposure to a predatory invasive insect stressor, the red imported fire ant (Solenopsis invicta), on the morphology and survival of the eastern fence lizard (Sceloporus undulatus). We captured gravid lizards from high-stress populations with long histories of invasion by fire ants and from uninvaded sites. Resulting hatchlings were exposed weekly to one of the three treatments until they reached maturity (42 weeks): (1) sub-lethal attack by fire ants; (2) topical application of the stress-relevant hormone, corticosterone (CORT), to mimic the stress of fire ant attack; or (3) control handling. Exposure to post-natal early life stress (fire ants or CORT) did not interact with a population's evolutionary history of stress to affect morphology or survival and early life stress did not affect these fitness relevant traits. However, morphology and survival were associated with the lizards' evolutionary history of exposure to fire ants. Offspring of lizards from fire ant invaded sites had longer and faster growing hind-limbs, gained body length and lost condition more slowly in the first 16 weeks, and had lower in-lab survival to 42 weeks, compared to lizards from uninvaded sites. These results suggest that a population's history of stress/invasion caused by fire ants during ca. 38 generations may be more important in driving survival-relevant traits than are the early life experiences of an organism. PMID- 29189941 TI - Vortioxetine: Clinical Pharmacokinetics and Drug Interactions. AB - Vortioxetine is a novel antidepressant with multimodal activity currently approved for the treatment of major depressive disorder. Vortioxetine is orally administered once daily at 5- to 20-mg doses. The pharmacokinetics of vortioxetine are linear and dose proportional, with a mean terminal half-life of approximately 66 h and steady-state plasma concentrations generally achieved within 2 weeks of dosing. The mean absolute oral bioavailability of vortioxetine is 75%. No food effect on pharmacokinetics was observed. Vortioxetine is metabolized by cytochrome P450 enzymes and subsequently by uridine diphosphate glucuronosyltransferase. The major metabolite is pharmacologically inactive, and the minor pharmacologically active metabolite is not expected to cross the blood brain barrier, making the parent compound primarily responsible for in-vivo activity. No clinically relevant differences were observed in vortioxetine exposure by sex, age, race, body size, and renal or hepatic function. Dose adjustment is only recommended for cytochrome P450 2D6 poor metabolizers based on polymorphism of the cytochrome P450 enzymes involved. Similarly, except for bupropion, a strong cytochrome P450 2D6 inhibitor, and rifampin, a broad cytochrome P450 inducer, co-administration of other drugs evaluated did not affect the vortioxetine exposure or safety profile in any clinically meaningful way. Pharmacodynamic studies demonstrated that vortioxetine achieved high levels of serotonin transporter occupancy in relevant brain areas, affected neurotransmitter levels in the cerebrospinal fluid, and modified abnormal resting state networks in the brain over the therapeutic dose range. Overall, vortioxetine can be administered in most populations studied to date without major dose adjustments; however, dose adjustments should be considered on a patient-by-patient basis. PMID- 29189940 TI - The relationship between dietary protein content, body condition, and Delta15N in a mammalian omnivore. AB - Seasonal reductions in food availability may cause animals to catabolize endogenous tissue and the resulting loss of lean mass can hinder their ability to forage and reproduce. While several studies have considered nitrogen isotopes (delta15N) as an indicator of catabolism, relationships between protein intake, body condition, and tissue delta15N have not been assessed simultaneously in controlled conditions. We conducted a feeding experiment on laboratory mice (Mus musculus) to test the effects of low (5%) versus high (30-40%) dietary protein content on lean mass, fat mass, and tissue delta15N. This approach enables the distinction between use of exogenous and endogenous nitrogen, illuminating a framework of protein metabolism and tissue synthesis. As expected, lean mass and body fat were lower in mice fed low-protein diets. Nitrogen isotope discrimination (Delta15N) between blood plasma-diet and liver-diet did not differ between diet treatments. In contrast, Delta15N for hair decreased while Delta15N for muscle and RBC increased in the low-protein treatment. These patterns suggest that animals in negative nitrogen balance catabolize labile endogenous protein (e.g., muscle) to maintain vital tissues (e.g., liver) required to survive. Consequently, muscle and RBC delta15N values appear to be the most useful in assessing the nutritional state of animals. Our combination of direct measurements of body condition with delta15N analysis suggest how nitrogen isotopes can be better used as tracers of catabolic and anabolic activity by demonstrating connections between tissue-specific metabolic processes and Delta15N, thus refining the application of delta15N as a tool for assessing nitrogen balance in wild animals. PMID- 29189943 TI - Relieving one's relatives from the burdens of care. AB - It has been proposed that an old and ill person may have a 'duty to die', i.e. to refuse life-saving treatment or to end her own life, when she is dependent on the care of intimates and the burdens of care are becoming too heavy for them. In this paper I argue for three contentions: (1) You cannot have a strict duty to die, correlating to a claim-right of your relatives, because if they reach the point at which the burdens of care are larger than you can reasonably expect them to take, the natural conclusion is that their duty ends. (2) They may be prepared, however, to go on caring for you beyond that point. In that case your responsibility for their wellbeing may require you to refuse this care, even if this results in a situation for you in which death will be preferable to continued life. (3) If this is the correct understanding of your responsibilities, the objection that in the context of family life the burdens of care attached to one family member's valued existence can never be 'too heavy', fails. It postulates unlimited concern on one side and a total lack of concern on the other. PMID- 29189944 TI - The ultrastructural alterations in the lens capsule and epithelium in eyes with traumatic white cataract. AB - PURPOSE: To demonstrate the morphological and physiological characteristics of lens epithelial cells (LECs) in patients with traumatic cataract using transmission electron microscopy (TEM) to further understand penetrating ocular injury-induced cataract morphology and epithelial repair mechanisms involved at a cellular level. METHODS: This is a prospective international study. Sixteen eyes of 16 consecutive patients who were diagnosed as traumatic white cataracts following the anterior lens capsule perforation and 13 eyes of 13 patients with idiopathic posterior subcapsular cataract were included to the study. The anterior lens capsules (aLCs: basement membrane and associated LECs) were obtained from cataract surgery and prepared for TEM. RESULTS: Two prominent cell types were observed in all aLCs of the traumatic cases: degenerated type LECs having variable sized intraepithelial vacuoles close to injury site and normal appearing LECs having an euchromatic nucleus distant from the injury site. In control group, the LECs and all their elements were in normal ultrastructural pattern except some small intraepithelial vacuoles, which were fewer and smaller than the vacuoles in the degenerated LECs of the traumatic group. CONCLUSIONS: The ultrastructural findings of our cases support that traumatically induced dysfunction of the lens epithelium may lead to an edema in superficial cortical lens fibers that subsequently undergo degeneration and produce a localized zone of vacuolization. PMID- 29189945 TI - Could adverse effects and complications of selective laser trabeculoplasty be decreased by low-power laser therapy? AB - Selective laser trabeculoplasty (SLT) has been used for treatment of primary open angle glaucoma, ocular hypertension, pigmenter and pseudoexfoliative glaucoma being considered a low-risk procedure. Therefore, transitory and permanent adverse effects have been reported, including corneal changes, subclinical edema, and reduction in endothelial cells and in central corneal thickness. Despite rarer, serious corneal complications after SLT can be permanent and lead to visual impairment, central corneal haze, opacity and narrowing. The mechanism involves increase of vasoactive and chemotactic cytokines causing inflammatory infiltrate, destruction of stromal collagen by fibroblasts and increase of matrix metalloproteinases type 2, which impair reepithelization. SLT also increases free radical production and reduces antioxidant enzymes, resulting in endothelium damages. Low-power laser therapy (LPLT) has been used in regenerative medicine based on its biostimulatory and anti-inflammatory effects. Biostimulation occurs through the interaction of laser photons with cytochrome C oxidase enzyme, which activates intracellular biochemical cascades causing synthesis of a number of molecules related to anti-inflammatory, regenerative effects, pain relief and reduction in edema. It has been showed that LPLT reduces gene expression related to pro-inflammatory cytokines and matrix metalloproteinases, and it increases expression of growth factors related to its proliferative and healing actions. Although radiations emitted by low-power lasers are considered safe and able to induce therapeutic effects, researches based on experimental models for glaucoma could bring important data if LPLT could be an alternative approach to improve acceptation for patients undergoing SLT. PMID- 29189942 TI - The Conspicuity of CRISPR-Cpf1 System as a Significant Breakthrough in Genome Editing. AB - Clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR associated protein (Cas) is a microbial adaptive immune system. CRISPR-Cas systems are classified into two main classes and six types. Cpf1 is a putative type V (class II) CRISPR effector, which has revolutionized the genome editing approaches through multiple distinct features such as using T-rich protospacer adjacent motif, applying a short guide RNA lacking trans-activating crRNA, introducing a staggered double-strand break, and possessing RNA processing activity in addition to DNA nuclease activity. In the present review, we attempt to highlight most recent advances in CRISPR-Cpf1 (CRISPR-Cas12a) system in particular, considering ground expeditions of the nature and the biology of this system, introducing novel Cpf1 variants that have broadened the versatility and feasibility of CRISPR-Cpf1 system, and lastly the great impact of the CRISPR-Cpf1 system on the manipulation of the genome of prokaryotic, mammalian, and plant models is summarized. With regard to recent developments in utilizing the CRISPR Cpf1 system in genome editing of various organisms, it can be concluded with confidence that this system is a reliable molecular toolbox of genome editing approaches. PMID- 29189946 TI - Treatment results in aphakic patients with glaucoma following congenital cataract surgery. AB - PURPOSE: To evaluate the clinical findings and possible risk factors of patients with aphakic glaucoma following congenital cataract surgery and identify the factors affecting response to glaucoma treatment. METHODS: A retrospective chart review of 173 patients was performed who underwent congenital cataract surgery before the age of 12 months and 40 eyes of 25 patients with aphakic glaucoma were enrolled. Age of the patients at the time of the cataract surgery, postoperative complications, additional ocular pathologies and the type of glaucoma treatment needed were investigated. RESULTS: Mean age of 25 patients at the time of cataract surgery was 3.31 +/- 2.28 (range 1-11) months with a mean follow-up period of 79 +/- 30.5 (32-176) months. Out of 40 eyes, medical therapy was effective in 20 (50%) eyes, whereas 20 (50%) eyes needed surgery for glaucoma. In these 20 eyes, 6 (30%) eyes underwent only 1, 4 (20%) eyes underwent 2 and 10 (50%) eyes underwent 3 or more procedures. Age at the time of cataract surgery, pupillary membrane formation and additional ocular pathologies were not significantly associated both with the need for glaucoma surgery or the number of operations (p >= 0.05). CONCLUSION: Aphakic glaucoma following congenital cataract surgery is a serious complication which requires surgery in half (50%) of the patients. Usually, more than one surgical procedure (70%) is needed. It can be detected even years after cataract surgery (range 0.3-94 months), so long term careful follow-up is necessary.

AB - PURPOSE: To evaluate the effects of retinitis pigmentosa (RP) on time, frequency, and time-frequency components of Xenon flash ERG signals using Fourier and wavelet transforms. METHODS: Xenon flash ERG was done in 18 eyes of nine RP patients and 20 normal eyes. After examining latency and amplitude, Fourier and wavelet transforms were performed using MATLAB software. Then, we extracted the mode frequency from the Fourier transform and main frequencies and their occurrence time from the wavelet transform. Finally, mean differences were analyzed using statistical tests. RESULTS: The results indicated increased latency and reduced ERG wave amplitude, no significant inter-group difference in the average mode frequency, and significant reduction in main signal frequencies and their increased occurrence times. Also one or two of the three main frequencies had disappeared in more advanced cases. CONCLUSION: Retinitis pigmentosa can induce changes in ERG time and time-frequency components. Impacted areas can be identified more accurately by wavelet transform and converting scales to frequencies. PMID- 29189949 TI - ?

AB - OBJECTIVES: Ventilator-associated pneumonia (VAP) is the most frequent hospital acquired infections in intensive care units (ICU). In the bundle of care to prevent the VAP, the oral care is very important strategies, to decrease the oropharyngeal bacterial colonization and presence of causative bacteria of VAP. In view of the paucity of medical economics studies, our objective was to determine the cost of implementing this oral care program for preventing VAP. MATERIALS AND METHODS: In five ICUs, during period 1, caregivers used a foam stick for oral care and, during period 2, a stick and tooth brushing with aspiration. Budgetary effect of the new program from the hospital's point of view was analyzed for both periods. The costs avoided were calculated from the incidence density of VAP (cases per 1000 days of intubation). The cost study included device cost, benefit lost, and ICU cost (medication, employer and employee contributions, blood sample analysis...). RESULTS: A total of 2030 intubated patients admitted to the ICUs benefited from oral care. The cost of implementing the study protocol was estimated to be ?11,500 per year. VAP rates decreased significantly between the two periods (p1 = 12.8% and p2 = 8.5%, p = 0.002). The VAP revenue was ranged from ?28,000 to ?45,000 and the average cost from ?39,906 to ?42,332. The total cost assessment calculated was thus around ?1.9 million in favor of the new oral care program. CONCLUSION AND CLINICAL RELEVANCE: Our study showed that the implementation of a simple strategy improved the quality of patient care is economically viable. TRIAL REGISTRATION: NCT02400294.

AB - A molecular screening for tick-borne pathogens was carried out in engorged and in questing ticks collected in Verbano Cusio Ossola county, Piemonte region, Italy. Engorged ticks were removed from wild and domestic animal hosts. The most abundant and common tick species in the area was Ixodes ricinus (192 adults, 907 nymphs). Few individuals of Ixodes hexagonus (15) and Rhipicephalus sanguineus (7) were found among the ticks removed from domestic animals (46 examined ticks). The presence of Rickettsia spp., Borrelia burgdorferi sensu latu, Francisella tularensis and Coxiella burnetii was evaluated by PCR and sequencing in 392 individuals of I. ricinus (adult and nymphal stages) and 22 individuals of the two other tick species. Five Borrelia species (i.e. B. burgdorferi sensu stricto, B. garinii, B. afzelii, B. valaisiana and B. lusitaniae), proved or suspected to cause clinical manifestations of Lyme disease in humans, showed 10.5 and 2.2% combined prevalence in questing and engorged I. ricinus, respectively. In addition, two species of rickettsiae (R. helvetica and R. monacensis) were identified and reported with 14.5 and 24.8% overall prevalence in questing and in engorged ticks. The prevalence of F. tularensis in the ticks collected on two wild ungulate species (Capreolus capreolus and Cervus elaphus) was 5.7%. This work provided further data and broadened our knowledge on bacterial pathogens present in ticks in Northwest Italy. PMID- 29189952 TI - Immuno-proteomic analysis of Trichinella spiralis, T. pseudospiralis, and T. papuae extracts recognized by human T. spiralis-infected sera. AB - The present study explored potentially immunogenic proteins of the encapsulated (Trichinella spiralis) and non-encapsulated (T. pseudospiralis, T. papuae) species within the genus Trichinella. The somatic muscle larval extracts of each species were subjected to immunoblotting analysis using human T. spiralis infected serum samples. Fifteen reactive bands of all three species were selected for further protein identification by liquid chromatography-tandem mass spectrometry, and their possible functions were ascertained using the gene ontology. Our findings showed immunogenic protein patterns with molecular mass in the range of 33-67 kDa. Proteomic and bioinformatic analysis revealed a wide variety of functions of 17 identified proteins, which are associated with catalytic, binding, and structural activities. Most proteins were involved in cellular and metabolic processes that contribute in the invasion of host tissues and the larval molting processes. The parasite proteins were identified as actin 5C, serine protease, deoxyribonuclease-2, and intermediate filament protein ifa 1. This information may lead to alternative tools for selection of potential diagnostic protein markers or aid in the design of vaccine candidates for prevention and control of Trichinella infection.

AB - A series of novel N-(4-methyl-3-((4-(pyridin-3-yl)pyrimidin-2 yl)amino)phenyl)piperidine-4-carboxamide derivatives 10(a-f), 12(a-c) and 14(a-c) were synthesized and characterized by FTIR, 1H-NMR, mass spectral and elemental analysis. The efficacy of these derivatives to inhibit in vivo angiogenesis was evaluated using chick chorioallantoic membrane (CAM) model and their DNA cleavage abilities were evaluated after incubating with calf thymus DNA followed by gel electrophoresis. These novel piperidine analogues efficiently blocked the formation of blood vessels in vivo in CAM model and exhibited differential migration and band intensities in DNA binding/cleavage assays. Among the tested compounds 10a, 10b, 10c, 12b, 14b and 14c showed significant anti-angiogenic and DNA cleavage activities compared to their respective controls and the other derivatives used in this study. These observations suggest that the presence of electron donating and withdrawing groups at positions 2, 3 and 4 of the phenyl ring of the side chain may determine their potency and as anticancer agents by exerting both anti-angiogenic and cytotoxic effects .

AB - PURPOSE: The objective of the study was to compare results of treatment for chronic recurrent temporomandibular joint dislocation (CRTMD) by autologous blood injection (ABI) using two different methods of administration (combination intra- and peri-articular, and peri-articular alone). MATERIALS AND METHODS: Forty patients diagnosed with CRTMD were randomly divided into two groups of 20 each (A and B). Group A were treated by intra- and peri-articular blood injection, group B were treated by peri-articular injection alone. The follow-up was done at 1, 3, 6, and 12 months. The study assessed presence of dislocations, pain (VAS, 0-10), interincisal mouth opening (IMO), and the presence of sound phenomena. The treatment was considered successful in patients without the persistence of CRTMD symptoms, as well as with a VAS of 0-1. RESULT: After 12 months, a beneficial therapeutic effect in group B was seen in 11 patients, while 16 patients from group A had a therapeutic effect. CONCLUSION: Intra- and peri-articular ABI is more effective than peri-articular blood application alone in the treatment of CRTMD, although the difference was not statistically significant.

AB - Dental papilla cells (DPCs) belong to precursor cells differentiating to odontoblasts and play an important role in dentin formation and reproduction. This study aimed to explore the changes and and involvement of mitochondrial respiratory function during odontogenic differentiation. Primary DPCs were obtained from first molar dental papilla of neonatal rats and cultured in odontogenic medium for 7, 14, 21 days. DPCs, which expressed mesenchymal surface markers CD29, CD44 and CD90, had the capacity for self-renewal and multipotent differentiation. Odontoblastic induction increased mineralized matrix formation in a time-dependent manner, which was accompanied by elevated alkaline phosphatase (ALP), dentin sialophosphoprotein and dentin matrix protein 1 expression at mRNA and protein levels. Notably, odontogenic medium led to an increase in adenosine-5'-triphosphate content and mitochondrial membrane potential, whereas a decrease in intercellular reactive oxygen species production and NAD+/NADH ratio. Furthermore, odontogenic differentiation was significantly suppressed by treatment with rotenone, an inhibitor of mitochondrial respiratory chain. These results demonstrate that enhanced mitochondrial function is crucial for odontogenic differentiation of DPCs.

AB - Actin is a multi-functional gene family that can be divided into muscle-type actins and non-muscle-type actins. In this study, 37 unigenes encoding actins were identified from RNA-Seq data of Pacific white shrimp, Litopenaeus vannamei. According to phylogenetic analysis, four and three cDNAs belong to cytoplasmic- and heart-type actins and were named LvActinCT and LvActinHT, respectively. 10 cDNAs belong to the slow-type skeletal muscle actins, and 18 belong to the fast type skeletal muscle actins; they were designated LvActinSSK and LvActinFSK, respectively. Some muscle actin genes formed gene clusters in the genome. Multiple alternative transcription starts sites (ATSSs) were found for LvActinCT1. Based on the early developmental expression profile, almost all LvActins were highly expressed between the early limb bud and post-larval stages. Using LvActinSSK5 as probes, slow-type muscle was localized in pleopod muscle and superficial ventral muscle. We also found three actin genes that were down regulated in the hemocytes of white spot syndrome virus (WSSV)- and Vibrio parahaemolyticus-infected L. vannamei. This study provides valuable information on the actin gene structure of shrimp, furthers our understanding of the shrimp muscle system and helps us develop strategies for disease control and sustainable shrimp farming.

AB - The objective of this paper is analyzing the effects of preoperative embolization on intraoperative blood loss in spinal surgery for renal cell carcinoma (RCC) metastasis and identifying factors contributing to an increased blood loss in the surgical procedure. A retrospective analysis was performed in patients who were treated in for spinal metastasis from RCC between 2011 and 2016. Factors analyzed were reduction of tumor blush, timing of embolization, selective vs. superselective approach, surgical factors, and tumor volume and localization. Parameters were statistically correlated with intraoperative blood loss (hemoglobin (Hg) decrease, blood loss in milliliters, number of transfused blood bags). Twenty-five patients with 34 surgical interventions were included. Seventeen cases were treated superselectively and 11 treated selectively. Mean perioperative blood loss was 2248 +/- 1833 ml. Higher blood loss was detected for vertebra replacement compared to percutaneous procedures (Hg decrease 4.22 vs. 2.62, p < 0.05). Blood loss increased with increasing tumor volumes (0-50 ccm/50 100 ccm/> 100 ccm) for Hg loss (3.29/3.64/4.24 mg/dl, NS), blood loss in milliliters (1291/2620/4971 ml, p < 0.001), and number of transfusions (1.2/3.4/7.0, p < 0.001). Stratifying by the grade of embolization, no significant differences were found between the groups (> 90%/90-75%/75-50%) for Hg loss, blood loss, or number of transfusions. Endovascular embolization for RCC metastasis of the spine is a safe procedure; however, in this cohort, patients undergoing embolization did not show a reduced blood loss in comparison to the non-embolized cohort. Additional factors contributing to an increased blood loss were tumor size and mode of surgery. PMID- 29189959 TI - Molecular dynamics calculation on structures, stabilities, mechanical properties, and energy density of CL-20/FOX-7 cocrystal explosives. AB - In this article, different CL-20/FOX-7 cocrystal models were established by the substitution method based on the molar ratios of CL-20:FOX-7. The structures and comprehensive properties, including mechanical properties, stabilities, and energy density, of different cocrystal models were obtained and compared with each other. The main aim was to estimate the influence of molar ratios on properties of cocrystal explosives. The molecular dynamics (MD) simulation results show that the cocrystal model with molar ratio 1:1 has the best mechanical properties and highest binding energy, so the CL-20/FOX-7 cocrystal model is more likely to form in 1:1 M ratio. The detonation parameters show that the cocrystal explosive exhibited preferable energy density and excellent detonation performance. In a word, the 1:1 cocrystal model has the best comprehensive properties, is very promising, and worth more theoretical investigations and experimental tests. This paper gives some original theories to better understand the cocrystal mechanism and provides some helpful guidance and useful instructions to help design CL-20 cocrystal explosives.

PMID- 29189961 TI - Feasibility of endoscopic resection using bipolar snare for nonampullary duodenal tumours in familial adenomatous polyposis patients. AB - The management of duodenal and colorectal tumours is important in patients with familial adenomatous polyposis (FAP). Endoscopic resection (ER) should be carefully performed because the risk of complications during or after (ER) of nonampullary duodenal tumours is higher than that of stomach or colorectal lesions in general. Thus, we evaluated the feasibility of endoscopic resection using bipolar snare (ERB) for nonampullary duodenal tumours in FAP patients. Eleven FAP patients who underwent ERB for nonampullary duodenal tumours at our hospital between October 2013 and December 2016 were retrospectively analysed based on clinicopathological features. ER was generally indicated for endoscopically diagnosed tumours > 20 mm, biopsy-confirmed high-grade dysplasia or carcinomas > 10 mm, and multiple tumours. Nineteen endoscopic treatments were performed and 134 nonampullary duodenal tumours were resected. The median patient age at initial treatment was 40 years (range 20-64), and median size of the largest tumour in each procedure was 16 mm (range 9-40). Of the 101 pathologically evaluated lesions, 10 tumours were high-grade tubular adenomas, 87 were low-grade tubular adenomas, 1 was an adenocarcinoma, and 3 were non neoplastic mucosal polyps. No intraoperative or delayed perforations were observed. Melena was encountered in one patient and managed without emergent endoscopic intervention. ERB for nonampullary duodenal tumours of FAP patients is feasible and effective, even for large lesions with high-grade dysplasia. Long term outcomes of ERB, including local recurrence and prognosis, should be monitored. PMID- 29189962 TI - Metachronous colorectal cancer following segmental or extended colectomy in Lynch syndrome: a systematic review and meta-analysis. AB - Around 5% of colorectal cancers are due to mutations within DNA mismatch repair genes, resulting in Lynch syndrome (LS). These mutations have a high penetrance with early onset of colorectal cancer at a mean age of 45 years. The mainstay of surgical management is either a segmental or extensive colectomy. Currently there is no unified agreement as to which management strategy is superior due to limited conclusive empirical evidence available. A systematic review and meta- analysis to evaluate the risk of metachronous colorectal cancer (MCC) and mortality in LS following segmental and extensive colectomy. A systematic review of the PubMed database was conducted. Studies were included/ excluded based on pre-specified criteria. To assess the risk of MCC and mortality attributed to segmental or extensive colectomies, relative risks (RR) were calculated and corresponding 95% confidence intervals (CI). Publication bias was investigated using funnel plots. Data about mortality, as well as patient ascertainment [Amsterdam criteria (AC), germline mutation (GM)] were also extracted. Statistical analysis was conducted using the R program (version 3.2.3). The literature search identified 85 studies. After further analysis ten studies were eligible for inclusion in data synthesis. Pooled data identified 1389 patients followed up for a mean of 100.7 months with a mean age of onset of 45.5 years of age. A total 1119 patients underwent segmental colectomies with an absolute risk of MCC in this group of 22.4% at the end of follow-up. The 270 patients who had extensive colectomies had a MCC absolute risk of 4.7% (0% in those with a panproctocolecomy). Segmental colectomy was significantly associated with an increased relative risk of MCC (RR = 5.12; 95% CI 2.88-9.11; Fig. 1), although no significant association with mortality was identified (RR = 1.65; 95% CI 0.90 3.02). There was no statistically significant difference in the risk of MCC between AC and GM cohorts (p = 0.5, Chi-squared test). In LS, segmental colectomy results in a significant increased risk of developing MCC. Despite the choice of segmental or extensive colectomies having no statistically significant impact on mortality, the choice of initial surgical management can impact a patient's requirement for further surgery. An extensive colectomy can result in decreased need for further surgery; reduced hospital stays and associated costs. The significant difference in the risk of MCC, following segmental or extensive colectomies should be discussed with patients when deciding appropriate management. An individualised approach should be utilised, taking into account the patient's age, co-morbidities and genotype. In order to determine likely germline-specific effects, or a difference in survival, larger and more comprehensive studies are required. PMID- 29189963 TI - Multiple true-false items: a comparison of scoring algorithms. AB - Multiple true-false (MTF) items are a widely used supplement to the commonly used single-best answer (Type A) multiple choice format. However, an optimal scoring algorithm for MTF items has not yet been established, as existing studies yielded conflicting results. Therefore, this study analyzes two questions: What is the optimal scoring algorithm for MTF items regarding reliability, difficulty index and item discrimination? How do the psychometric characteristics of different scoring algorithms compare to those of Type A questions used in the same exams? We used data from 37 medical exams conducted in 2015 (998 MTF and 2163 Type A items overall). Using repeated measures analyses of variance (rANOVA), we compared reliability, difficulty and item discrimination of different scoring algorithms for MTF with four answer options and Type A. Scoring algorithms for MTF were dichotomous scoring (DS) and two partial credit scoring algorithms, PS50 where examinees receive half a point if more than half of true/false ratings were marked correctly and one point if all were marked correctly, and PS1/n where examinees receive a quarter of a point for every correct true/false rating. The two partial scoring algorithms showed significantly higher reliabilities (alphaPS1/n = 0.75; alphaPS50 = 0.75; alphaDS = 0.70, alphaA = 0.72), which corresponds to fewer items needed for a reliability of 0.8 (nPS1/n = 74; nPS50 = 75; nDS = 103, nA = 87), and higher discrimination indices (rPS1/n = 0.33; rPS50 = 0.33; rDS = 0.30; rA = 0.28) than dichotomous scoring and Type A. Items scored with DS tend to be difficult (pDS = 0.50), whereas items scored with PS1/n become easy (pPS1/n = 0.82). PS50 and Type A cover the whole range, from easy to difficult items (pPS50 = 0.66; pA = 0.73). Partial credit scoring leads to better psychometric results than dichotomous scoring. PS50 covers the range from easy to difficult items better than PS1/n. Therefore, for scoring MTF, we suggest using PS50. PMID- 29189964 TI - The birth and death of curricula.

AB - Alemtuzumab is a humanized monoclonal antibody indicated for the treatment of adult patients with relapsing-remitting multiple sclerosis with active disease. Multiple sclerosis (MS) patients treated with alemtuzumab are at increased risk for autoimmune adverse events (thyroid disorders, immune thrombocytopenia, and renal disease). The use of alemtuzumab has been associated with the development of renal immune-mediated adverse events in 0.3% of patients in clinical trials in MS, which generally occurred within 39 months of the last administration. Both anti-GBM disease and membranous nephropathy have been associated with the use of alemtuzumab. Early detection is necessary to allow for early diagnosis and prevent adverse renal and patient outcomes. Through the implementation of the risk minimization measures, patients can be diagnosed, and treated if needed, early allowing for generally favorable outcomes. This important goal can be reached through health care professional and patient education, careful analysis of the monthly lab tests, and close collaboration between the patient, neurologist, and the nephrologist. This article presents the consensus of Belgian MS specialists and nephrologists on the practicalities of diagnosis, management, and treatment of alemtuzumab-associated renal adverse events based on good clinical practice. PMID- 29189968 TI - Detection of electrocardiographic changes in partial epileptic patients using local binary pattern based composite feature. AB - In this paper, we propose a novel method for detecting electrocardiographic (ECG) changes in partial epileptic patients using a composite feature set. At the core of our approach is a local binary pattern (LBP) based feature representation containing a set of statistical features derived from the distribution of LBPs of the ECG signal. In order to enhance the discriminating power, a set of statistical features are also extracted from the original ECG signal. The composite feature is then generated by combining the two homogeneous feature sets. The discriminating ability of the proposed composite feature is investigated using two different classifiers namely, support vector machine and a bagged ensemble of decision trees. Results from the experimental evaluation on the publicly available MIT-BIH ECG dataset demonstrate the superiority of the proposed features over conventional histogram based LBP features. Our results also show that the proposed approach provides better classification accuracy than methods existing in the literature for classification of normal and partial epileptic beats in ECG. PMID- 29189967 TI - Evaluation of a specialized oncology nursing supportive care intervention in newly diagnosed breast and colorectal cancer patients following surgery: a cluster randomized trial. AB - BACKGROUND: Better coordination of supportive services during the early phases of cancer care has been proposed to improve the care experience of patients. We conducted a randomized trial to test a community-based nurse-led coordination of care intervention in cancer patients. METHODS: Surgical practices were cluster randomized to a control group involving usual care practices or a standardized nursing intervention consisting of an in-person supportive care assessment with ongoing support to meet identified needs, including linkage to community services. Newly diagnosed breast and colorectal cancer patients within 7 days of cancer surgery were eligible. The primary outcome was the patient-reported outcome (PRO) of continuity of care (CCCQ) measured at 3 weeks. Secondary outcomes included unmet supportive care needs (SCNS), quality of life (EORTC QLQ C30), health resource utilization, and level of uncertainty with care trajectory (MUIS) at 3 and/or 8 weeks. RESULTS: A total of 121 breast and 72 colorectal patients were randomized through 28 surgical practices. There was a small improvement in the informational domain of continuity of care (difference 0.29 p = 0.05) and a trend to less emergency room use (15.8 vs 7.1%) (p = 0.07). There were no significant differences between groups on unmet need, quality of life, or uncertainty. CONCLUSION: We did not find substantial gaps in the PROs measured immediately following surgery for breast and colorectal cancer patients. The results of this study support a more targeted approach based on need and inform future research focused on improving navigation during the initial phases of cancer treatment.

PMID- 29189970 TI - Climate change-induced heat risks for migrant populations working at brick kilns in India: a transdisciplinary approach. AB - During the summer of 2015, India was hit by a scorching heat wave that melted pavements in Delhi and caused thousands of deaths, mainly among the most marginalized populations. One such group facing growing heat risks from both occupational and meteorological causes are migrant brick kiln workers. This study evaluates both current heat risks and the potential future impacts of heat caused by climate change, for the people working at brick kilns in India. A case study of heat stress faced by people working at brick kilns near Chennai, India, is the anchor point around which a transdisciplinary approach was applied. Around Chennai, the situation is alarming since occupational heat exposure in the hot season from March to July is already at the upper limits of what humans can tolerate before risking serious impairment. The aim of the study was to identify new pathways for change and soft solutions by both reframing the problem and expanding the solution space being considered in order to improve the quality of life for the migrant populations at the brick kilns. Technical solutions evaluated include the use of sun-dried mud bricks and other locally "appropriate technologies" that could mitigate the worsening of climate change-induced heat. Socio-cultural solutions discussed for empowering the people who work at the brick kilns include participatory approaches such as open re-localization, and rights-based approaches including the environmental sustainability and the human rights-based approach framework. Our analysis suggests that an integrative, transdisciplinary approach could incorporate a more holistic range of technical and socio-culturally informed solutions in order to protect the health of people threatened by India's brick kiln industry. PMID- 29189973 TI - Somatosensory evoked potentials after decompressive craniectomy for traumatic brain injury. AB - Somatosensory evoked potentials (SSEPs) are used for neuroprognosis after severe traumatic brain injury (TBI). However decompressive craniectomy (DC), involving removal of a portion of the skull to alleviate elevated intracranial pressure, is associated with an increase in SSEP amplitude. Accordingly, SSEPs are not available for neuroprognosis over the hemisphere with DC. We aim to determine the degree to which SSEP amplitudes are increased in the absence of cranial bone. This will serve as a precursor for translation to clinically prognostic ranges. Intra-operative SSEPs were performed before and after bone flap replacement in 22 patients with severe TBI. SSEP measurements were also performed in a comparison non-traumatic group undergoing craniotomy for tumor resection. N20/P25 amplitudes and central conduction time were measured with the bone flap in (BI) and out (BO). Linear regressions, adjusting for skull thickness and study arm, were performed to evaluate the contribution of bone presence to SSEP amplitudes. Latencies were not different between BO or BI trials in either group. Mean N20/P25 amplitudes recorded with BO were statistically different (p = 0.0001) from BI in both cohorts, showing an approximate doubling in BO amplitudes. For contralateral-ipsilateral montages r2 was 0.28 and for frontal pole montages r2 was 0.62. Cortical SSEP amplitudes are influenced by the presence of cortical bone as is particularly evident in frontal pole montages. Larger, longitudinal trials to assess feasibility of neuroprognosis over the hemisphere with DC in severe TBI patients are warranted. PMID- 29189972 TI - Plasma lipopolysaccharide-binding protein and colorectal cancer risk: a nested case-control study in the Multiethnic Cohort. AB - BACKGROUND: Lipopolysaccharide (LPS), an endotoxin found on the outer cell wall of Gram-negative bacteria, increases inflammatory response signaling and may play a role in the pathogenesis of several adverse outcomes, including inflammatory bowel diseases, cardiovascular disease, and cancer. While LPS is hypothesized to be associated with colorectal carcinogenesis, there are relatively few human studies which have examined this association. METHODS: We examined the association between colorectal cancer (CRC) and plasma lipopolysaccharide-binding protein (LBP), a marker of LPS, in 1,638 participants (819 CRC cases and 819 controls) matched on multiple factors, including age, sex, and race/ethnicity, from the Multiethnic Cohort study. Conditional logistic regression models were used to estimate the multivariable-adjusted odds ratios (OR) and 95% confidence intervals (95% CI). RESULTS: Compared to individuals whose LBP concentrations were in the lowest quartile, the ORs associated with second, third, and fourth quartiles were 1.23 (95% CI 0.91-1.67), 1.36 (95% CI 1.01-1.83), and 1.01 (95% CI 0.73-1.39), respectively, (p trend = 0.66). No differences were observed by BMI, fiber intake, saturated fat intake, cancer site, or cancer stage. CONCLUSIONS: This study did not find an overall statistically significant association between LBP (as a marker of LPS exposure) and CRC. Further prospective studies with multiple LBP measurements are needed to validate current findings. PMID- 29189974 TI - Association of SIRT1 gene polymorphism and its expression for the risk of alcoholic fatty liver disease in the Han population. AB - OBJECTIVE: To investigate the associations between SIRT1 polymorphisms and their expression in patients with alcoholic fatty liver disease (AFLD). METHODS: A total of 268 heavy drinkers were divided into the AFLD group (n = 176) and alcoholic control (n = 92) and 237 light-/non-drinkers into the NAFLD (non-AFLD) group (n = 117) and healthy control (n = 120). The genotyping of SIRT1 (rs33957861, rs11599176, rs12413112 and rs35689145) was detected by the Sequenom MassARRAY iPLEX test. The mRNA and protein expressions of SIRT1 were determined by quantitative real-time polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assays (ELISA), respectively. RESULTS: SIRT1 gene rs33957861 and rs11599176 polymorphisms significantly reduce the risk of NAFLD and AFLD, while rs35689145 remarkably increases the risk. Haplotypes of AAAA (rs33957861 rs11599176-rs12413112-rs35689145), AAAA, CAGA and CGAA can appreciably lower the presence of AFLD, but CAAG had an elevated AFLD risk. Besides, in the NAFLD and AFLD groups, a decreased BMI was found in the mutant genotype carriers of rs33957861, rs11599176 and rs12413112, but an increased BMI was observed in the rs35689145 mutant genotype carriers when compared to those with the wild-type homozygous genotype ones. Furthermore, rs33957861 C>T, rs11599176 A>G and BMI were independent risk factors of AFLD. There was no difference among four SNPs of SIRT1 and its mRNA and protein expressions in all groups. CONCLUSION: SIRT1 polymorphisms and their expression were associated with the presence of AFLD, and there was a close relationship among four SNPs and BMI in AFLD patients, but no SNP was related to its expression. PMID- 29189975 TI - Trends in the medication reviews of community pharmacies in Japan: a nationwide retrospective study. AB - Background The trends in medication reviews made by community pharmacies in Japan are currently unknown. Objective We aimed to comprehensively describe the national trends in medication reviews in Japan's community pharmacies in the backdrop of the country's ageing population. Setting Community pharmacies in Japan. Methods We analysed national health insurance claims data for 2010-2015. These data were provided by the Ministry of Health, Labour and Welfare as part of the Survey of Medical Care Activities in Public Health Insurance. Main outcome measures The national trends in community pharmacy visits involving medicine dispensing and medication reviews that involve consultations with a physician. Results Among the 365 million pharmacy visits for 2010-2015, we identified 373,429 medication reviews accompanied by consultations with a physician. The pharmacy visit rate per 1000 population increased from 427.2 in 2010 to 483.7 in 2015. Medication reviews also increased from 407 per million pharmacy visits in 2010 to 1445 in 2015. Among the 373,429 medication reviews during the study period, the prescription was changed through collaboration with a physician 338,982 times (90.4%). The proportion of medication review acceptance increased from 80.6% in 2010 to 94.8% in 2015. The prescription change rate was higher among older patients than among younger ones. Conclusions Medication reviews by community pharmacists involving consultations with a physician increased in Japan from 2010 to 2015, as did prescription changes following these reviews.

AB - Background Although it can result in serious complications due to its narrow therapeutic index, warfarin is widely used in the treatment and prevention of thromboembolic disorders. However, patients' adherence and knowledge are determinants of therapeutic success. Objective We sought to validate instruments to provide a reliable means of identifying gaps in patient understanding and nonadherence to inform targeted pharmacists' interventions to improve these measures. Methods A cross-sectional survey was conducted. Patients' knowledge about warfarin was rated using an Arabic-language tool. Medication adherence was assessed using the eight-item Morisky Medication Adherence Scale (MMAS-8). The international normalized ratio (INR) control was quantified by the Rosendaal Method. Setting At the Security Forces hospital anticoagulant clinic (ACC), Riyadh. Main outcome measure Validity of a Knowledge and adherence tool. Results Totally, 101 patients completed the questionnaires. Interestingly, the knowledge tool demonstrated good internal consistency (total Cronbach's alpha = 0.75) and significant concurrent validity with adherence levels. Fifty-two patients were classified as having unsatisfactory knowledge. Deficiency in knowledge was most obvious with respect to the consequences of missing a dose and when to seek immediate medical attention. The MMAS-8 had moderate reliability (Cronbach's alpha = 0.65); however, its concurrent validity with good INR control was not demonstrated. Conclusions This study revealed high prevalence of nonadherence and poor knowledge in the population visiting the ACC. Given that available knowledge and adherence tools seemed to have little validity in predicting clinical outcomes, structured tools should be designed, considering progression in clinical outcomes with future pharmacists' interventions. PMID- 29189977 TI - Efficacy and safety of atypical antipsychotics for behavioral symptoms of dementia among patients residing in long-term care. AB - Background There are limited options for the treatment of behavioral and psychological symptoms of dementia (BPSD). Objective Evaluate the efficacy and safety of using atypical antipsychotics for BPSD among patients residing in long term care. Setting Long term care community facility in the United States. Methods Retrospective observational study of patients residing in a long-term care facility with a diagnosis of dementia not trauma-induced with documented BPSD treated with an atypical antipsychotic for at least 2 weeks. Paper medical records were reviewed from January 1, 1990 until March 23, 2010. Main outcome measure Behavioral/psychological efficacy outcomes were documented beginning 2 weeks after atypical antipsychotic therapy was initiated and safety outcomes were documented from the time of atypical antipsychotic initiation, until the last documentation available. Efficacy and safety outcomes were documented as part of routine clinical practice based on the responsible clinician. Results A total of 85 distinct atypical antipsychotic treatment periods for 73 unique patients were included. Nearly 50% of patients continued atypical antipsychotic treatment for at least 1 year and 5.6% of treatments were discontinued due to an adverse event. Patients' behavioral/psychological outcomes improved for 52 (61%) treatments, remained stable for 17 (20%) treatments, and worsened for 16 (19%) treatments. Adverse events were reported by 57% of patients, with the most common adverse events being metabolic, fall related, and extrapyramidal symptoms. The odds ratio for an adverse event was 1.08 (p = 0.03) for every 90 day increase in duration of treatment. Conclusion In patients who reside in a long-term care setting, atypical antipsychotic treatment improved BPSD, but also increased the potential risk of adverse events. PMID- 29189978 TI - Disordered eating attitudes and emotional/behavioral adjustment in Greek adolescents. AB - PURPOSE: The aim of this study was to examine the relationship between disordered eating attitudes and emotional/behavioral adjustment in Greek adolescents as well as the moderating role of gender and body mass index (BMI) in this relationship. METHODS: Ninety adolescents, 11-18 years old, were assessed using anthropometric measurements; demographics, eating attitudes and level of emotional/behavioral adjustment were examined via self-reported questionnaires. RESULTS: Disordered eating attitudes were prevalent in 17.8% of the sample. A significant relationship was found between disordered eating attitudes and Youth Self-Report (YSR) anxiety score (r = .22, p < .05). Gender significantly moderated the relationship between YSR anxiety symptoms and Eating Attitudes Test (EAT) scores (b = .59, p = .01) and this effect held true for the EAT bulimia subscale (b = .20, p = .03), but not for the dieting or the oral control subscales. Contrary to our hypothesis, BMI did not moderate the relationship between EAT and YSR anxiety sub-scores (b = .13, p > .05). CONCLUSION: Girls with elevated anxiety levels appear to be at risk for exhibiting disordered eating attitudes, especially bulimic behaviors. This finding highlights the importance of developing gender based preventive interventions tailored to these specific emotional/behavioral aspects. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study. PMID- 29189979 TI - Comparison of biophysical properties characterized for microtissues cultured using microencapsulation and liquid crystal based 3D cell culture techniques. AB - Growing three dimensional (3D) cells is an emerging research in tissue engineering. Biophysical properties of the 3D cells regulate the cells growth, drug diffusion dynamics and gene expressions. Scaffold based or scaffoldless techniques for 3D cell cultures are rarely being compared in terms of the physical features of the microtissues produced. The biophysical properties of the microtissues cultured using scaffold based microencapsulation by flicking and scaffoldless liquid crystal (LC) based techniques were characterized. Flicking technique produced high yield and highly reproducible microtissues of keratinocyte cell lines in alginate microcapsules at approximately 350 +/- 12 pieces per culture. However, microtissues grown on the LC substrates yielded at lower quantity of 58 +/- 21 pieces per culture. The sizes of the microtissues produced using alginate microcapsules and LC substrates were 250 +/- 25 MUm and 141 +/- 70 MUm, respectively. In both techniques, cells remodeled into microtissues via different growth phases and showed good integrity of cells in field-emission scanning microscopy (FE-SEM). Microencapsulation packed the cells in alginate scaffolds of polysaccharides with limited spaces for motility. Whereas, LC substrates allowed the cells to migrate and self-stacking into multilayered structures as revealed by the nuclei stainings. The cells cultured using both techniques were found viable based on the live and dead cell stainings. Stained histological sections showed that both techniques produced cell models that closely replicate the intrinsic physiological conditions. Alginate microcapsulation and LC based techniques produced microtissues containing similar bio-macromolecules but they did not alter the main absorption bands of microtissues as revealed by the Fourier transform infrared spectroscopy. Cell growth, structural organization, morphology and surface structures for 3D microtissues cultured using both techniques appeared to be different and might be suitable for different applications. PMID- 29189980 TI - Patients with type 1 diabetes mellitus have impaired IL-1beta production in response to Mycobacterium tuberculosis. AB - Patients with diabetes mellitus have an increased risk of developing tuberculosis. Although the underlying mechanism is unclear, evidence suggests a role for chronic hyperglycaemia. We examined the influence of hyperglycaemia on Mycobacterium tuberculosis-induced cytokine responses in patients with type 1 diabetes mellitus (T1D). Peripheral blood mononuclear cells (PBMCs) from 24 male T1D patients with sub-optimal glucose control [HbA1c > 7.0% (53 mmol/L)] and from 24 age-matched male healthy controls were stimulated with M. tuberculosis lysate. Cytokine analysis, assessment of aerobic glycolysis, receptor recognition and serum cross-over experiments were performed to explore the mechanistic differences. PBMCs from T1D patients produced less bioactive interleukin (IL) 1beta in response to M. tuberculosis. IL-6 and interferon (IFN)-gamma production trended towards a decrease, whilst other cytokines such as tumour necrosis factor (TNF)-alpha, IL-17 and IL-1Ra were normal. The decrease in cytokine production was not correlated to HbA1c or plasma glucose levels. Cross-over serum experiments did not alter the cytokine profile of T1D or control patients, arguing for an intrinsic cellular defect. Cellular metabolism and the expression of M. tuberculosis-related pattern recognition receptors (PRRs) such as TLR2, TLR4 and NOD2 did not differ between T1D patients and healthy controls. Compared to matched controls, T1D patients have a reduced capacity to produce pro inflammatory cytokines in response to M. tuberculosis. The impaired IL-1beta production in T1D patients may contribute to the increased susceptibility to tuberculosis. This effect appears not to be related to prevailing glucose levels but to an intrinsic cellular deficit. PMID- 29189981 TI - Healthcare associated bloodstream infections in Polish hospitals: prevalence, epidemiology and microbiology-summary data from the ECDC Point Prevalence Survey of Healthcare Associated Infections 2012-2015. AB - Aggregated data from the Polish Point Prevalence Survey of Healthcare Associated Infections and Antimicrobial Use (PPS HAI&AU) collected between 2012 and 2015 were used to describe the epidemiology of healthcare associated bloodstream infections (BSI) in Polish hospitals, in order to assess the rationale for introducing a BSI surveillance programme in our country and analyse selected risk factors. Data were collected according to the ECDC PPS HAI&AU protocol. Within four years, records for 71,039 patients were collected in 36 (2012), 32 (2013), 112 (2014), and 158 (2015) hospitals; representativeness was evaluated as good in 2012-2013, and excellent from 2014. HAI was found in 4,258 of these patients; laboratory confirmed BSI, including catheter related infections (CRI), and neonatal BSI accounted for 7.7% (329 cases). A representative control group was selected during a random selection process. Out of 329 cases of BSI, 48.9% were associated with vascular access, and 70.8% of them met the criteria of (CRI). The most frequently isolated microorganisms were Staphylococci with 150 isolates (45.6%). Most of them were coagulase-negative (64.4%) that usually caused CRI. Out of 53 S. aureus isolates 24.5% were methicillin-resistant. Enterobacteriaceae were responsible for 31.3% of BSI (n = 103), 50.0% of them were resistant to third generation cephalosporins and 6 (5.8%) to carbapenems. Since little is known about the epidemiology of BSI in Poland, introduction of a countrywide surveillance programme based on incidence is justified, in order to create national prevention initiatives based on local epidemiology, as well as bundle focusing on prevention of CRI. PMID- 29189982 TI - How Infertility Patients and Providers View and Confront Religious and Spiritual Issues. AB - Questions arise concerning whether and how religion affects infertility treatment decisions. Thirty-seven infertility providers and patients were interviewed. Patients confront religious, spiritual, and metaphysical issues coping with treatment failures and religious opposition from clergy and others. Religion can provide meaning and support, but poses questions and objections that patients may try to avoid or negotiate-e.g., concealing treatment or changing clergy. Differences exist within and between religions. Whether and how much providers discuss these issues with patients varies. These data, the first to examine several key aspects of how infertility providers and patients confront religious/spiritual issues, have important implications for practice, research, guidelines, and education. PMID- 29189983 TI - Patient Appreciation of Student Chaplain Visits During Their Hospitalization. AB - Spiritual care is associated with improved health outcomes and higher patient satisfaction. However, chaplains often cover many hospital units and thus may not be able to serve all patients. Involving student chaplains in patient spiritual care may allow for more patients to experience the support of spiritual care. In this study, we surveyed 93 patients hospitalized on general medical units at a tertiary care center who were visited by nine student chaplain summer interns. The results indicated that the majority of patients appreciated student chaplain visits and these encounters may have positively influenced their overall hospital experience. Thus, student chaplains could be a way to extend valuable spiritual care in settings where chaplaincy staff shortages preclude access. PMID- 29189984 TI - The role of resveratrol on skeletal muscle cell differentiation and myotube hypertrophy during glucose restriction. AB - Glucose restriction (GR) impairs muscle cell differentiation and evokes myotube atrophy. Resveratrol treatment in skeletal muscle cells improves inflammatory induced reductions in skeletal muscle cell differentiation. We therefore hypothesised that resveratrol treatment would improve muscle cell differentiation and myotube hypertrophy in differentiating C2C12 myoblasts and mature myotubes during GR. Glucose restriction at 0.6 g/L (3.3 mM) blocked differentiation and myotube hypertrophy versus high-glucose (4.5 g/L or 25 mM) differentiation media (DM) conditions universally used for myoblast culture. Resveratrol (10 uM) treatment increased SIRT1 phosphorylation in DM conditions, yet did not improve differentiation when administered to differentiating myoblasts in GR conditions. Resveratrol did evoke increases in hypertrophy of mature myotubes under DM conditions with corresponding elevated Igf-I and Myhc7 gene expression, coding for the 'slow' type I MYHC protein isoform. Inhibition of SIRT1 via EX-527 administration (100 nM) also reduced myotube diameter and area in DM conditions and resulted in lower gene expression of Myhc 1, 2 and 4 coding for 'intermediate' and 'faster' IIx, IIa and IIb protein isoforms, respectively. Resveratrol treatment did not appear to modulate phosphorylation of energy sensing protein AMPK or protein translation initiator P70S6K. Importantly, in mature myotubes, resveratrol treatment was able to ameliorate reduced myotube growth in GR conditions over an acute 24-h period, but not over 48-72 h. Overall, resveratrol evoked myotube hypertrophy in DM conditions while favouring 'slower' Myhc gene expression and acutely ameliorated impaired myotube growth observed during glucose restriction. PMID- 29189986 TI - 1H, 13C, and 15N chemical shift assignments of a G-quadruplex forming sequence within the KRAS proto-oncogene promoter region. AB - Single stranded guanine rich DNA (or RNA) sequences adopt noncanonical secondary structures called G-quadruplexes (G4). Functionally, quadruplexes control gene transcription and regulate activities such as replication, gene recombination or alternative splicing. Hence they are potential targets for cancer, neuronal, and viral related diseases. KRAS is one of the most mutated oncogenes in the genome of cancer cells and contains a nuclease hypersensitive element (NHE) sequence capable of forming G-quadruplexes via its six runs of guanines. In our work, we are interested in the NMR structure of the major G4 scaffold formed in the KRAS NHE region with a mutated sequence of 22 residues. Here, we report 1H, 13C and 15N chemical shift assignments the G4 formed within KRAS22RT sequence. PMID- 29189985 TI - Evaluation of the effect of the new methoxy-stilbenes on expression of receptors and enzymes involved in estrogen synthesis in cancer breast cells. AB - Our previous study showed that the new synthetic methoxy-stilbenes, 3,4,2' trimethoxy-trans-stilbene (3MS), 3,4,2',4'-tetramethoxy-trans-stilbene (4MS), and 3,4,2',4',6'-pentamethoxy-trans-stilbene (5MS), modulate the constitutive expression of enzymes and receptors involved in estrogen metabolism in breast immortalized epithelial MCF10 cells. In this study, we evaluated the effect of 3MS, 4MS, and 5MS in comparison to resveratrol activity in MCF7 estrogen dependent and MDA-MB-231 estrogen-independent breast cancer cell lines. 3MS similarly to resveratrol reduced the expression of estrogen receptor alpha in MCF7 cells. However, in these cells, 5MS reduced the most CYP19, the gene encoding aromatase, at mRNA transcript level. In contrast, in the MDA-MB-231 cells, the most efficient inhibitor of CYP19 expression was 3MS, reducing the level of its protein by ~ 25%. This stilbene also inhibited the aromatase activity in a recombinant protein system with IC50 value ~ 85 uM. Treatment with the methoxy-stilbenes reduced the level of estradiol in culture medium. The most significant reduction was exerted by 3MS. None of the tested stilbenes including resveratrol changed significantly the expression of AhR, although CYP1A1 protein level was slightly reduced in MDA-MB-231 cells, while CYP1B1 expression was increased in these cells as a result of treatment with 3MS, but only at the transcript level. Overall, these results show weak or moderate effect of the new methoxy-stilbenes on the expression of key proteins involved in estrogens metabolism in cancer breast cells. However, the reduced CYP19 expression and activity upon 3MS treatment in metastatic MDA-MB-231 cells require the further studies. PMID- 29189987 TI - Lessons Learned from the Young Breast Cancer Survivorship Network. AB - The Young Breast Cancer Survivors Network (Network) is an academic and community based partnership dedicated to education, support, and networking. The Network used a multi-pronged approach via monthly support and networking, annual education seminars, website networking, and individual survivor consultation. Formative and summative evaluations were conducted using group survey and individual survivor interviews for monthly gatherings, annual education meetings, and individual consultation. Google Analytics was applied to evaluate website use. The Network began with 4 initial partnerships and grew to 38 in the period from 2011 to 2017. During this 5-year period, 5 annual meetings (598 attendees), 23 support and networking meetings (373), and 115 individual survivor consultations were conducted. The Network website had nearly 12,000 individual users and more than 25,000 page views. Lessons learned include active community engagement, survivor empowerment, capacity building, social media outreach, and network sustainability. The 5-year experiences with the Network demonstrated that a regional program dedicated to the education, support, networking, and needs of young breast cancer survivors and their families can become a vital part of cancer survivorship services in a community. Strong community support, engagement, and encouragement were vital components to sustain the program.

PMID- 29189988 TI - Predictors of self-reported health-related quality of life according to the EQ-5D Y in chronically ill children and adolescents with asthma, diabetes, and juvenile arthritis: longitudinal results. AB - PURPOSE: Health-related quality of life (HRQoL) is an important patient-reported outcome in clinical and health research. The EQ-5D-Y assesses child and adolescent HRQoL by five items on mobility, self-care, usual activities, pain/discomfort, and anxiety/depression as well as a visual analogue scale (VAS) on the current health state. This study investigates predictors of self-reported HRQoL according to the EQ-5D-Y in chronically ill children and adolescents using longitudinal data. METHODS: Data from the German Kids-CAT study on children and adolescents with asthma, diabetes, and juvenile arthritis gathered over a period of six months were analyzed (n = 310; 7-17 years old; 48% female). Self-, parent , and pediatrician-reported data were collected from June 2013 to October 2014. Generalized linear mixed models and linear mixed models served to examine effects of socio-demographic as well as disease- and health-specific predictors on the items as well as on the VAS of the EQ-5D-Y. RESULTS: Ceiling effects for the EQ 5D-Y indicated low burden of disease in the analyzed sample. Longitudinal analyses revealed associations between less health complaints and better HRQoL for all investigated HRQoL domains. Further, age- and gender-specific effects, and associations of better disease control, longer duration of the disease and less mental health problems with better HRQoL were found. CONCLUSIONS: Subjective health complaints and mental health problems should be considered in the care of children and adolescents with asthma, diabetes, and juvenile arthritis. Future research should suggest administering the items of the EQ-5D-Y with five instead of three response options, and investigate HRQoL over a longer period. PMID- 29189990 TI - Importance of background values in assessing the impact of heavy metals in river ecosystems: case study of Tisza River, Serbia. AB - The main objective of this paper is to evaluate how a choice of different background values may affect assessing the anthropogenic heavy metal pollution in sediments from Tisza River (Serbia). The second objective of this paper is to underline significance of using geochemical background values when establishing quality criteria for sediment. Enrichment factor (EF), geoaccumulation index (I geo), pollution load index (PLI), and potential ecological risk index (PERI) were calculated using different background values. Three geochemical (average metal concentrations in continental crust, average metal concentrations in shale, and average metal concentrations in non-contaminated core sediment samples) and two statistical methods (delineation method and principal component analyses) were used for calculating background values. It can be concluded that obtained information of pollution status can be more dependent on the use of background values than the index/factor chosen. The best option to assess the potential river sediment contamination is to compare obtained concentrations of analyzed elements with concentrations of mineralogically and texturally comparable, uncontaminated core sediment samples. Geochemical background values should be taken into account when establishing quality criteria for soils, sediments, and waters. Due to complexity of the local lithology, it is recommended that environmental monitoring and assessment include selection of an appropriate background values to gain understanding of the geochemistry and potential source of pollution in a given environment. PMID- 29189991 TI - CSN5 Promotes Hepatocellular Carcinoma Progression by SCARA5 Inhibition Through Suppressing beta-Catenin Ubiquitination. AB - BACKGROUND: Increasing evidence has suggested that E3 Ubiquitin Ligase CSN5 is a newly characterized oncogene involved in various types of cancer. Scavenger receptor class A member 5 (SCARA5) is an important regulator of biological processes in cancer cells. However, the roles and relationship of CSN5 and SCARA5 in hepatocellular carcinoma (HCC) remain unclear. METHODS: We used RT-PCR, Western blot, and immunohistochemistry to measure CSN5 and SCARA5 expression in HCC tissues and corresponding non-tumor tissues. The CSN5 gene was overexpressed or silenced with lentiviral vectors in HCC cells. Cell proliferation was measured using CCK8 assay. And, the cell migration and invasion were analyzed by transwell assay. RESULTS: We found that the expressions of CSN5 and SCARA5 are inversely correlated in HCC tissues, and CSN5 expression levels were negatively correlated with the levels of SCARA5 in various HCC cells. Furthermore, we found that high level of CSN5 expression correlated closely with tumor TNM stage, tumor size, and venous metastasis, but low level of SCARA5 expression correlated closely with tumor TNM stage, tumor size, and venous metastasis. Additionally, survival of patients with lower expression of CNS5 was significantly better than that of higher expression group, but the survival of patients with higher expression of SCARA5 was significantly better than that of lower expression group. Moreover, knockdown of CSN5 increased SCARA5 expression and inhibited the proliferation and metastasis of HCC cells in vitro and in vivo. Finally, we found that CSN5 regulated SCARA5 expression by modulating beta-catenin. Mechanistically, our results indicate that CSN5 can decrease beta-catenin ubiquitination to enhance the protein expression of SCARA5 in HCC cells. CONCLUSIONS: Our data identified CSN5 as a critical oncoprotein involved in progression of HCC cells, which could serve as a potential therapeutic target in HCC patients. PMID- 29189992 TI - Effects of exergaming on cardiovascular risk factors and adipokine levels in women. AB - The aim of this study was to examine the effects of exergaming on the cardiovascular risk factors and adipokine levels of women engaged in the music video game Just Dance using the Xbox 360 Kinect console. Triglycerides, total cholesterol, HDL, LDL, FFA, CRP, TNF-alpha, Il-1beta, IL-6, leptin, and resistin were measured in sedentary women before and 1 month after the practice of exergaming. We also evaluated anthropometric parameters. Our results indicate that total serum cholesterol, triglycerides, and LDL were reduced by 64, 29, and 12%, respectively. HDL levels were not altered in the conditions of this study. A significant decrease was also found in the concentrations of TNF-alpha (57%), CRP (84.7%), resistin (68.4%), leptin (35%), FFA (90%), body mass index (10.5%), fat percentage (10.9%), weight (5.6%), abdominal circumference (2.3%), hip circumference (2.5%), and waist circumference (1.9%) after the training period. We concluded that exergaming was successful in reducing body fat, serum adipokine levels, and lipid profiles, thus reducing cardiovascular risks for women. PMID- 29189993 TI - Barriers to Physical and Mental Health: Understanding the Intersecting Needs of Cambodian and Latino Residents in Urban Communities. AB - A community needs assessment was conducted to explore barriers and facilitators to good physical and mental health among Cambodian and Latino residents in an urban community in Southern California. Thirty-six Cambodians and 29 Latinos completed the interviewer-facilitated survey administered door-to-door, and another 20 Cambodian and 18 Latino residents participated in focus groups. Crime, limited knowledge of positive health behaviors, lack of access to affordable healthcare, and lack of access to safe spaces for recreational activities were identified as threats to good health. Participant recommendations to support health in the community included increasing police presence to improve safety and reduce violence, and increasing opportunities/locations for physical exercise. While differences between Cambodian and Latino residents exist, the identified threats and suggested improvements were primarily associated with environmental factors, highlighting the need for systems level approaches that recognize the relationship between community context and health. PMID- 29189994 TI - Impact of a Usual Source of Care on Health Care Use, Spending, and Quality Among Adults With Mental Health Conditions. AB - Physical comorbidities associated with mental health conditions contribute to high health care costs. This study examined the impact of having a usual source of care (USC) for physical health on health care utilization, spending, and quality for adults with a mental health condition using Medicaid administrative data. Having a USC decreased the probability of inpatient admissions and readmissions. It decreased expenditures on emergency department visits for physical health, 30-day readmissions, and behavioral health inpatient admissions. It also had a positive effect on several quality measures. Results underscore the importance of a USC for physical health and integrated care for adults with mental health conditions. PMID- 29189996 TI - Zinc Sulphate Mediates the Stimulation of Cell Proliferation of Rat Adipose Tissue-Derived Mesenchymal Stem Cells Under High Intensity of EMF Exposure. AB - Unlike the role of mesenchymal stem cells (MSCs) in regenerative medicine, their application in cell therapy can be complicated by factors such as a reduction in the proliferation potential, senescent tendency of MSCs to expand, and an age dependent decline in their number and functions. It was shown that there is an association between exposure to electromagnetic fields (EMFs) and response to stress, cell proliferation, aging, and cell death. Furthermore, the zinc ion, as an essential trace element, was reported to be involved in the regulation of the growth and cell proliferation. In this report, ratadipose tissue-derived mesenchymal stem cells (rADSCs) were randomly divided into four groups-group I (control without any ZnSO4 and EMF); group II (ZnSO4 treatment without EMF exposed); group III (EMF exposed without ZnSO4); and group IV (EMF exposed with ZnSO4)-to evaluate whether 0.14 MUg/ml Zinc sulfate (ZnSO4) could affect cell proliferation of rADSCs under extremely low frequency-electromagnetic field (ELF EMF). The methyl thiazoltetrazolium (MTT) method was used to determine the cell proliferation of rADSCs following exposure to ELF-EMF in the presence of ZnSO4. The immunocytochemistry method as well as flow-cytometry was used to identify the cell surface markers. Next, oil red O, alizarin red, toluidine blue, and cresyl violet staining was done to evaluate the adipogenic, osteogenic, chondrogenic, and neurogenic differentiation of rADSCs as the pluripotent capacity of rADSCs, respectively. The results showed that an exposure to ELF-EMF caused a decrease in the proliferation of rADSCs. However, the ZnSO4 supplementation significantly increased the cell proliferation of ELF-EMF-exposed rADSCs. In addition, in the presence of 0.14 MUg/ml ZnSO4, rADSCs appeared to be growing faster than the control group and ZnSO4 significantly decreased the doubling time of ELF-EMF exposed rADSCs. It seems that ZnSO4 would be a good element to induce the cell proliferation of ELF-EMF-exposed rADSCs. PMID- 29189995 TI - Acetyl-L-Carnitine Attenuates Arsenic-Induced Oxidative Stress and Hippocampal Mitochondrial Dysfunction. AB - Augmentation of mitochondrial oxidative stress through activating a series of deadly events has implicated as the main culprit of arsenic toxicity and therapeutic approaches based on improving mitochondrial function hold a great promise for attenuating the arsenic-induced toxicity. Acetyl-L-carnitine (ALC) through balancing the coenzyme A (CoA)/acyl-CoA ratio plays an important role in mitochondrial metabolism and thereby can help protect hippocampal neurons from oxidative damage. In the present study, we aimed to explore the effect of arsenic interactions on the mitochondrial function in the hippocampus of rats. Rats were randomly divided into five groups of control (distilled water), sodium arsenite (NaAsO2, 20 mg/kg), and co-treatment of NaAsO2 with various doses of ALC in three groups (100, 200, 300 mg/kg) and were treated orally for 21 consecutive days. Our results point out that arsenic exposure caused oxidative stress in rats' hippocampus, which led to the reactive oxygen species (ROS) generation, mitochondrial swelling, the collapse of the mitochondrial membrane potential, and release of cytochrome c. It also altered Bcl-2/Bax expression ratio and increased caspase-3 and caspase-9 activities. Furthermore, arsenic exposure via activation of NF-kappaB and microglia increased inflammation. ALC could concentration dependently counteract the arsenic-induced oxidative stress, modulate the antioxidant defense capacity, and improve mitochondrial functions. In addition, ALC decreased the expression of both death-associated proteins and of inflammatory markers. These findings indicate that ALC improved the arsenic induced hippocampal mitochondrial dysfunction which underlines the importance of ALC in providing a possible therapeutic strategy for the prevention of arsenic induced neurodegeneration.

PMID- 29190000 TI - A genome-wide DNA methylation analysis in peripheral blood from patients identifies risk loci associated with Graves' orbitopathy. AB - OBJECTIVE: Graves' orbitopathy (GO) is an inflammatory orbital disease of autoimmune origin with the potential to cause severe functional and psychosocial effects. The pathogenesis has not been fully elucidated. We investigated whether DNA methylation was associated with GO incidence in Chinese patients. MATERIALS AND METHODS: Six GO patients and six age-matched controls were recruited, and genome-wide DNA methylation patterns were analyzed in their peripheral blood. t tests were performed to determine differential methylated sites in genomic regions and the univariable logistic regression analyses was performed to evaluate their risk with GO incidence. Cluster analysis and principal component analysis (PCA) were performed to determine the effects of the extracted differentially methylated sites. RESULTS: One hundred and forty-eight differentially methylated sites were identified, including CD14 (fold change = 4.31, p = 0.005), IL17RE (fold change = 2.128, p = 0.005), and DRD4 (fold change = 0.25, p = 0.004), and were supported by cluster and PCA analyses. Univariable logistic regression analyses showed that the methylation patterns at 12 loci were associated with GO incidence. The relative risk per 1% decrease in methylation at ZCCHC6 and GLI3 was 0.15 (95% CI 0.03-0.91; p = 0.039) and 0.65 (95% CI 0.42 0.98; p = 0.042), respectively. Pearson correlation analyses demonstrated that methylation levels at IL17RE were positively associated with Clinical Activity Score (CAS) (r = 0.967, p < 0.05). CONCLUSIONS: Our results demonstrate that differential methylation levels at analyzed sites (genes) may be risk markers of GO. DNA methylation analysis could provide new insights into understanding the disease and provide new treatment strategies for GO in Chinese patients. PMID- 29189999 TI - NAFLD/NASH in patients with type 2 diabetes and related treatment options. AB - Type 2 diabetes may reduce life expectancy and patients' quality of life due to its micro- and macro-vascular complications and to the higher risk of several types of cancer. An emerging important factor is represented by the hepatic involvement; it is recognized that excessive hepatic fat accumulation represents a typical feature of diabetic patients and that it also plays an important pathogenic role. It is now evident that non-alcoholic fatty liver disease (NAFLD), generally perceived as a benign condition, may have on the contrary an important deleterious impact for diabetic patients increasing the risk to develop cardiovascular complications but also serious hepatic diseases, in particular non alcoholic steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma. Lifestyle intervention, bariatric surgery and several drug therapies have now accumulated evidence of efficacy in treating NASH. On the other hand, their durability and safety in the long-term is yet to be proven and their use may be sometimes associated with side effects or higher risk of adverse events limiting the regular administration or contraindicating it. Professional health care providers, building awareness about the importance of these hepatic complications, should put more efforts in primary prevention using a behavioral therapy needing a multidisciplinary approach, in secondary prevention applying on a regular basis in the clinical setting available predictive algorithms to identify the patients at higher cardiovascular and hepatologic risk, and in tertiary prevention treating, when not contraindicated, the diabetic patients preferentially with drugs with proven benefit on NAFLD/NASH. PMID- 29190001 TI - Richness and Composition of Ground-dwelling Ants in Tropical Rainforest and Surrounding Landscapes in the Colombian Inter-Andean Valley. AB - Tropical rainforests are characterized by having high structural complexity, stratification, and species diversity. In Colombia, tropical rainforests are critically endangered with only 24% of their area remaining. Forest fragments are often valued based on the presence of vertebrate taxa despite that small habitat remnants may still harbor diverse invertebrate communities. We surveyed the ant fauna associated with rainforest fragments and their surrounding landscape elements (including mature forests, flooded forests, gallery forests, live fences, and pastures) in the Magdalena River watershed. Pitfall traps and litter samples were used to estimate ant richness and diversity, and to compare ant composition among landscape elements. We found 135 species from 42 genera, representing 16% of the species and 43% of the genera known for Colombia. Our surveys also uncovered 11 new ant records for the Colombian inter-Andean region and 2 new records for the country of Colombia: Mycocepurus curvispinosus (Mackay) and Rhopalothrix isthmica (Weber). The highest species richness was found in forest-covered sites, and richness and diversity was lower in the disturbed landscapes surrounding the forest patches. Species composition varied significantly between all habitat types, but was most similar between forest types suggesting that a loss of structural complexity has the greatest effect on ant communities. Across our study sites, ten species showed the greatest response to habitat type and could qualify as indicator taxa for this region. We conclude by discussing the value of conserving even small forests in this landscape due to their ability to retain high diversity of ants. PMID- 29190002 TI - Dentoalveolar Abscesses Not Associated with Caries or Trauma: A Diagnostic Hallmark of Hypophosphatemic Rickets Initially Misdiagnosed as Hypochondroplasia. AB - Hypophosphatemic rickets is a rare genetic disorder involving the regulation of fibroblast growth factor 23 (FGF23), a phosphaturic agent, clinically showing bowing of the legs, short stature and dentoalveolar abscesses. A 7-year-old boy, with previous hypochondroplasia diagnosis, was referred to our pediatric dentistry clinic presenting short stature, bone deformities and sinus tracts at deciduous teeth apex levels not related with trauma, restorations or dental caries. After deciduous teeth extraction, due to root resorption and mobility, light microscopy exhibited typical hypophosphatemic dentin, and micro-computed tomography revealed tubular clefts and porosities throughout the teeth. Laboratory tests confirmed the HR diagnosis, after which the treatment was initiated. PMID- 29190003 TI - p16 Immunohistochemistry in Oropharyngeal Squamous Cell Carcinoma Using the E6H4 Antibody Clone: A Technical Method Study for Optimal Dilution. AB - Routine testing for p16 immunohistochemistry (with selective HPV-specific test use) has been recommended for clinical practice in oropharyngeal squamous cell carcinoma (OPSCC). Data suggests that the E6H4 clone performs best for this purpose, yet no studies have evaluated the optimal antibody concentration for OPSCC testing. We evaluated three concentrations (undiluted, 1:5, and 1:10) of the primary antibody solution for E6H4 using tissue microarrays from a cohort of 199 OPSCC patients with a > 70% staining cutoff for positivity. Concordance was evaluated using percent agreement and Cohen's kappa. The concentrations were evaluated for sensitivity and specificity using high risk HPV RNA in situ hybridization (RNA-ISH) and also correlated with Kaplan-Meier overall survival analysis. Inter-rater agreement was very high between p16 results at each concentration and also with RNA in situ hybridization (p < 0.0001 for all). Agreement between p16 undiluted and 1:5 dilution (agreement 98.2%; Kappa 0.943; p < 0.0001) was very high and between p16 undiluted and 1:10 dilution (agreement 79.2%; Kappa 0.512; p < 0.0001) much lower. Intensity of the staining did decrease with the 1:5 and 1:10 dilutions compared to undiluted, but not in a manner that obviously would change test interpretation or performance. Results suggest that the E6H4 antibody performs well at dilutions of up to 1:5 fold with a minor decrease in staining intensity, minimum loss of sensitivity, and no loss of specificity in OPSCC patients. This could result in reagent and cost savings. PMID- 29190004 TI - Long-term safety and survival outcomes from the Scandinavian Breast Group 2004-1 randomized phase II trial of tailored dose-dense adjuvant chemotherapy for early breast cancer. AB - PURPOSE: Although adjuvant polychemotherapy improves outcomes for early breast cancer, the significant variability in terms of pharmacokinetics results in differences in efficacy and both short and long-term toxicities. Retrospective studies support the use of dose tailoring according to the hematologic nadirs. METHODS: The SBG 2004-1 trial was a randomized feasibility phase II study which assessed tailored dose-dense epirubicin and cyclophosphamide (EC) followed by docetaxel (T) (group A), the same regimen with fixed doses (group B) and the TAC regimen (group C). Women aged 18-65 years, ECOG PS 0-1 with at least one positive axillary lymph node were randomized 1:1:1. The primary endpoint of the study was the safety and feasibility of the treatment. Toxicity was graded according to CTC AE version 3.0. The design and short-term toxicity have been previously published. Here, we report safety and efficacy data after 10 years of follow-up. RESULTS: A total of 124 patients were included in the study. After a median follow-up of 10.3 years, the probability for 10-year survival was 78.5, 75.1, and 63.4% and for relapse free survival 64.1, 71.0, and 59.5% for groups A, B, and C, respectively. There were no cases of clinically diagnosed cardiotoxicity or hematologic malignancies. No patient was lost to follow-up. CONCLUSIONS: In this randomized phase II trial, tailored dose adjuvant chemotherapy was feasible, without an increased risk for long-term adverse events after a median follow-up of 10 years. PMID- 29190005 TI - Associations between ALDH1A1 polymorphisms, alcohol consumption, and mortality among Hispanic and non-Hispanic white women diagnosed with breast cancer: the Breast Cancer Health Disparities Study. AB - PURPOSE: ALDH1A1, one of the main isotopes of aldehyde dehydrogenase-1 is involved in the differentiation and protection of normal hematopoietic stem cells and functions in alcohol sensitivity and dependence. We evaluated the associations between ALDH1A1 polymorphisms, alcohol consumption, and mortality among Hispanic and non-Hispanic white (NHW) breast cancer (BC) cases from the Breast Cancer Health Disparities Study. METHODS: Nine SNPs in ALDH1A1 were evaluated in 920 Hispanic and 1372 NHW women diagnosed with incident invasive BC. Adjusted Cox proportional hazard regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Models were stratified by Native American (NA) ancestry and alcohol consumption. RESULTS: A total of 443 deaths occurred over a median follow-up time of 11 years. After adjusting all results for multiple comparisons, rs7027604 was significantly associated with all-cause mortality (HRAA = 1.40; 95% CI 1.13-1.73, P adj = 0.018). The rs1424482 CC genotype (HRCC = 1.69; 95% CI 1.20-2.37, P adj = 0.027) and the rs7027604 AA genotype (HRAA = 1.65; 95% CI 1.21-2.26, P adj = 0.018) were positively associated with non-BC mortality. Among long-term light drinkers, rs1888202 was associated with decreased all-cause mortality (HRCG/GG = 0.36; 95% CI 0.20-0.64), while associations were not significant among non-drinkers or moderate/heavy drinkers (P interation = 0.218). The increased risk of all-cause mortality associated with rs63319 was limited to women with low NA ancestry (HRAA = 1.53; 95% CI 1.19-1.97). CONCLUSIONS: Multiple SNPs in ALDH1A1 were associated with increased risk of mortality after BC. Future BC studies examining the relationship between ALDH1A1 and mortality should consider the modifying effects of alcohol consumption and NA ancestry. PMID- 29190007 TI - Body Satisfaction During Pregnancy: The Role of Health-Related Habit Strength. AB - Objectives Body satisfaction during pregnancy is an important determinant of maternal and fetal health outcomes. It is therefore critical to investigate factors related to changes in body satisfaction and to elucidate how body satisfaction changes over time in pregnant women. The purpose of this study was to examine the relation between two novel factors (i.e., healthy eating habit strength and physical activity habit strength) and body satisfaction during pregnancy. Methods Participants (n = 67 pregnant North American women) completed online questionnaires at the beginning of their second trimester (Time 1) and at the end of pregnancy. Maternal characteristics, relationship satisfaction, self esteem, and psychological distress were assessed at Time 1 and habit strength, body satisfaction, and weight were assessed at both time points. Results Strength of healthy eating and physical activity habits remained stable over time and body satisfaction decreased over time. Healthy eating habit strength at Time 1 predicted increases in body satisfaction from the second trimester to the end of pregnancy, even when controlling for gestational weight gain. Conclusions This study suggests that health-related habit strength in women of reproductive age may offer protection against low levels of body satisfaction during pregnancy. PMID- 29190006 TI - Trends in progression-free survival (PFS) and time to progression (TTP) over time within first-line aromatase inhibitors trials in hormone receptor-positive advanced breast cancer. AB - BACKGROUND: Over the last 20 years, aromatase inhibitors (AI) have been tested in clinical trials as first-line therapy for hormone receptor-positive (HR-positive) advanced breast cancer (ABC), firstly as experimental arms, when they proved to be effective, and recently as control arms. This analysis aims to evaluate trends in progression-free survival (PFS) and time to progression (TTP) over time. PATIENTS AND METHODS: A literature review was conducted using the MEDLINE database to identify randomized controlled phase II or III trials which reported PFS or TTP of at least one arm using first-line AI HR-positive ABC patients. A linear correlation was used to access the association between the year of the first patient enrolled and the observed PFS/TTP. RESULTS: The search retrieved 19 trials, accounting for 4552 postmenopausal patients divided into 21 separate AI treatment arms. The PFS/TTP increased from 6 to 9 months in the earlier trials to 13-16 months in the current era, representing an absolute gain of approximately 7 months, without the addition of any other drug. Our analysis showed a positive correlation between the year of the first patient enrolled in these trials and median PFS/TTP reported (R 2 = 0.34; p < 0.01). No correlation was found between the year of the first patient included in these trials and other potential prognostic factors such as visceral metastasis at baseline (R 2 = 0.26; p = 0.20) or exposure to adjuvant therapy (R 2 = 0.05; p = 0.18). CONCLUSION: Patients treated with first-line AIs in the more recently conducted trials have longer PFS/TTP when compared to their counterparts treated with the same drugs in older studies. These findings have important implications for the estimation of sample size and follow-up periods for the planning of future trials as well as in the translation of the results into clinical practice decisions. PMID- 29190008 TI - The Development of the Healthy Pregnancy Stress Scale, and Validation in a Sample of Low-Income African American Women. AB - Objectives The association of stress with pregnancy health is well-known. However, few studies take a mixed methods approach to understand the stressors contributing to a woman's pregnancy-related stress. Among African American women, exposure to stressors during pregnancy likely contributes to disparities in pregnancy health outcomes. This work aimed to understand the types and magnitude of stressors African American women are exposed to during pregnancy. Methods Using a mixed methods research design, we developed and administered the Healthy Pregnancy Stress Scale to measure stressors within the stress environment of African American women living in poverty. Results Exploratory factor analysis with one random split-half sample (N = 85) identified a two-factor model. Factor 1, defined as general pregnancy stressors, had significant loadings for ten items that ranged in magnitude from 0.319 to 0.724. Factor 2, defined as relationship strain, had significant loadings for three items ranging in magnitude from 0.613 to 0.856. Confirmatory factor analysis in the second random split-half sample (N = 88) showed a strong fit for the two factor model with factor loadings similar in magnitude. Standard fit statistics and those that adjust for item non normality suggested an adequate fit to the data (RMSEA = 0.057, CFI = 0.947, TLI = 0.932; Satorra-Bentler RMSEA = 0.037, CFI = 0.972, TLI = 0.965). Conclusions for Practice Our measurement tool may provide a way to determine differences in pregnancy stress experiences across diverse populations of women. Future research should include a test for construct validity by correlating the scale with other measures that should have a specific directional relationship in diverse populations. PMID- 29190009 TI - Introduction to the Special Issue on Healthy Start. PMID- 29190011 TI - Relevance of genetic relationship in GWAS and genomic prediction. AB - The objective of this study was to analyze the relevance of relationship information on the identification of low heritability quantitative trait loci (QTLs) from a genome-wide association study (GWAS) and on the genomic prediction of complex traits in human, animal and cross-pollinating populations. The simulation-based data sets included 50 samples of 1000 individuals of seven populations derived from a common population with linkage disequilibrium. The populations had non-inbred and inbred progeny structure (50 to 200) with varying number of members (5 to 20). The individuals were genotyped for 10,000 single nucleotide polymorphisms (SNPs) and phenotyped for a quantitative trait controlled by 10 QTLs and 90 minor genes showing dominance. The SNP density was 0.1 cM and the narrow sense heritability was 25%. The QTL heritabilities ranged from 1.1 to 2.9%. We applied mixed model approaches for both GWAS and genomic prediction using pedigree-based and genomic relationship matrices. For GWAS, the observed false discovery rate was kept below the significance level of 5%, the power of detection for the low heritability QTLs ranged from 14 to 50%, and the average bias between significant SNPs and a QTL ranged from less than 0.01 to 0.23 cM. The QTL detection power was consistently higher using genomic relationship matrix. Regardless of population and training set size, genomic prediction provided higher prediction accuracy of complex trait when compared to pedigree-based prediction. The accuracy of genomic prediction when there is relatedness between individuals in the training set and the reference population is much higher than the value for unrelated individuals. PMID- 29190012 TI - The Role of Glycemic Control and Variability in Diabetic Retinopathy. AB - Diabetic retinopathy (DR) is a common microvascular complication of diabetes mellitus (DM) and is considered the leading cause of visual impairment in working aged adults worldwide. The duration of DM and hyperglycemia have been associated with DR, although the exact role in the pathogenesis of DR and diabetic macular edema remains controversial. As a result, a reasonable question arising is whether control of blood glucose levels may alter the course of DR. Studies have shown that glycemic control remains an important factor for the presence and progression of DR. HbA1c seems to be an indicator which cannot demonstrate exactly the degree of glycemic control, while sudden variations of blood glucose may play an important role in DR; therefore, glycemic variability may be useful to predict DM complications, such as DR. PMID- 29190010 TI - Are mechanically sensitive regulators involved in the function and (patho)physiology of cerebral palsy-related contractures? AB - Skeletal muscle tissue is mechanosensitive, as it is able to sense mechanical impacts and to translate these into biochemical signals making the tissue adapt. Among its mechanosensitive nature, skeletal muscle tissue is the largest metabolic organ of the human body. Disturbances in skeletal muscle mechanosensing and metabolism cause and contribute to many diseases, i.e. muscular dystrophies/myopathies, cardiovascular diseases, COPD or diabetes mellitus type 2. A less commonly focused muscle-related disorder is clinically known as muscle contractures that derive from cerebral palsy (CP) conditions in young and adults. Muscle contractures are characterized by gradually increasing passive muscle stiffness resulting in complete fixation of joints. Different mechanisms have been identified in CP-related contractures, i.e. altered calcium handling, altered metabolism or altered titin regulation. The muscle-related extracellular matrix (ECM), specifically collagens, plays a role in CP-related contractures. Herein, we focus on mechanically sensitive complexes, known as costameres (Cstms), and discuss their potential role in CP-related contractures. We extend our discussion to the ECM due to the limited knowledge of its role in CP-related contractures. The aims of this review are (1) to summarize CP-related contracture mechanisms, (2) to raise novel hypotheses on the genesis of contractures with a focus on Cstms, and (3) to stimulate novel approaches to study CP-related contractures. PMID- 29190013 TI - Use of Animal Models and Techniques in Glaucoma Research: Introduction. AB - This chapter provides an overview over the use of animal models in glaucoma research from a historical perspective. Strengths and limitations of various models are considered, and the challenges of translating results in animal experiments to successful clinical trials in humans are discussed. PMID- 29190014 TI - Hypertonic Saline Injection Model of Experimental Glaucoma in Rats. AB - A reliable method of creating chronic elevation of intraocular pressure (IOP) in rodents is an important tool in reproducing and studying the mechanisms of optic nerve injury that occur in glaucoma. In addition, such a model could provide a valuable method for testing potential neuroprotective treatments. This paper outlines the basic methods for producing obstruction of aqueous humor outflow and IOP elevation by injecting hypertonic saline (a sclerosant) into the aqueous outflow pathway. This is one of several rodent glaucoma models in use today. In this method, a plastic ring is placed around the equator of the eye to restrict injected saline to the limbus. By inserting a small glass microneedle in an aqueous outflow vein in the episclera and injecting hypertonic saline toward the limbus, the saline is forced into Schlemm's canal and across the trabecular meshwork. The resultant inflammation and scarring of the anterior chamber angle occurs gradually, resulting in a rise in IOP after approximately 1 week. This article will describe the equipment necessary for producing this model and the steps of the technique itself. PMID- 29190015 TI - The Microbead Occlusion Model of Ocular Hypertension in Mice. AB - Glaucoma is a common optic neuropathy that leads to vision loss through the degeneration of retinal ganglion cells (RGCs) and their axons. RGC degeneration in glaucoma is associated with sensitivity to intraocular pressure (IOP) and elevated IOP (also known as ocular hypertension) is the primary modifiable risk factor. Ocular hypertension is the primary characteristic of rodent models for glaucoma research. Intracameral injection of microbeads has evolved as a preferred method of IOP elevation in rodents, particularly in mice. Here, we outline the protocol and method for the Microbead Occlusion Model in mice. We highlight the importance of anesthesia choice and the utilization of glass micropipettes in combination with a micromanipulator and microsyringe pump for the successful execution of the model. PMID- 29190016 TI - Ocular Hypertension/Glaucoma in Minipigs: Episcleral Veins Cauterization and Microbead Occlusion Methods. AB - Two methods to induce elevation of the intraocular pressure (experimental glaucoma) are described in the present chapter. The first method is based on increasing the post-trabecular resistance to aqueous outflow by cauterizing the episcleral veins (EVC). This method allows the observation of ultrastructural changes in the trabecular meshwork (TM) without interfering with any structure within the eye such as TM, ciliary body, and/or the Retina. The second method is the multiple injection of microbeads into the anterior chamber, as a pre and intra-trabecular method that induce secondary effects on the TM cells. Both methods lead to an increase in IOP. PMID- 29190017 TI - Noninvasive Intraocular Pressure Measurement in Animals Models of Glaucoma. AB - Intraocular pressure (IOP) elevation is a critical risk factor for development and progression of glaucoma. As such, measuring IOP in animal models of the disease is important for any research work trying to understand the pathophysiologic mechanisms of glaucoma. Noninvasive IOP measurement in animals uses methods that have been adapted from use on humans. Calibration of the instruments used for the specific animal and even strain used is critically important for allowing meaningful comparisons of results. We describe below the methods used for noninvasive IOP measurement in animals that are relevant to glaucoma research.

AB - We describe a new method for obtaining user-friendly, robust pattern electroretinograms (PERG) simultaneously from each eye using asynchronous binocular stimulation and one-channel acquisition of signals recorded from a subcutaneous needle in the snout. PMID- 29190019 TI - Visual Evoked Potentials in Glaucoma and Alzheimer's Disease. AB - Visual responses to gratings alternating in contrast have been studied in humans and several mammalian species. Previous evidence from human patients and animal models of neurodegeneration has highlighted the importance to record simultaneously the pattern electroretinogram (P-ERG) and visual evoked cortical potentials (VEPs) to investigate retinal and post-retinal sites of neurodegeneration.In view of the increasing importance of research on experimental models of neurodegenerative diseases, we present here the parametric properties of visual evoked responses in animal models of glaucoma and Alzheimer's disease. Glaucoma and Alzheimer's disease (AD) are two distinct multifactorial neurodegenerative and progressive diseases, primarily affecting the elderly. PMID- 29190020 TI - Investigation of the Functional Retinal Output Using Microelectrode Arrays. AB - Microelectrode array (MEA) recordings of the ex vivo flat-mounted retina enable the functional analysis of the retinal output. The electrical activity of a large portion of retinal ganglion cells (RGCs) is recorded simultaneously in response to various light stimuli. Analysis of the recorded time series of action potentials reveals physiological parameters such as firing rate, time latency, receptive field size, axonal conduction velocity. These parameters change during retinal diseases. PMID- 29190021 TI - Quantitative Proteomic Analysis of Human Aqueous Humor Using iTRAQ 4plex Labeling.

Here, we describe iTRAQ 4plex labeling of human aqueous humor specimens followed by ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) and data analysis for peptide identification and quantitation using Proteome Discoverer software. The protocol can be applied for other animals as well; however, pooling of specimens may be required to obtain sufficient amount of protein for labeling.

PMID- 29190023 TI - Assessment of Aqueous Humor Dynamics in the Rodent by Constant Flow Infusion. AB - Mice and rats are being increasingly used in glaucoma research and much useful data have been generated from them. One aspect of using these animals for this purpose involves assessment of aqueous humor dynamics. Several techniques have been described in the literature for the determination of one or more of these parameters in rodents, in both living animals and eyes perfused ex vivo. Here, we describe the practical details for a technique for the determination of all principal parameters of aqueous humor dynamics (intraocular pressure (IOP), aqueous humor formation rate (Fin), uveoscleral outflow rate (Fu), aqueous outflow facility (C), and episcleral venous pressure (Pe)) in the living rat and mouse eye, in a single experimental session. PMID- 29190024 TI - Methods for Analyzing Endoplasmic Reticulum Stress in the Trabecular Meshwork of Glaucoma Models. AB - The pathological mechanisms underlying increased outflow resistance at the trabecular meshwork (TM) that is responsible for elevating intraocular pressure (IOP) have not been fully delineated. Recent studies have shown that progressive accumulation of misfolded proteins and induction of endoplasmic reticulum (ER) stress is associated with the pathophysiology of glaucomatous TM damage and IOP elevation. We have shown that known causes of human glaucoma, including expression of mutant myocilin or dexamethasone treatment induce abnormal protein accumulation and ER stress in the TM in vitro and in vivo models. To cope up with abnormal protein accumulation, TM cells activate a cytoprotective pathway of unfolded protein response (UPR). However, chronic ER stress can lead to TM dysfunction and IOP elevation. Using cell culture, mouse models, and human postmortem tissues as well as genetic and pharmacological manipulations, we have analyzed ER stress and UPR mediators in the glaucomatous TM damage and IOP elevation. In this chapter, we have described a detailed protocol for the analysis of protein misfolding and ER stress in TM cells and tissues and its association with glaucomatous TM damage and IOP elevation. PMID- 29190025 TI - Quantification of Scleral Biomechanics and Collagen Fiber Alignment. AB - The stiffness of the sclera is important in several ocular disorders, and there is hence a need to quantify the biomechanical properties of this tissue. Here, we present two methods for measuring the stiffness of scleral ocular tissues: ocular compliance testing and digital image correlation strain mapping. In tandem with these approaches, we provide two methods to spatially quantify the anisotropic alignment of collagen fibers making up the sclera, using second harmonic generation microscopy and small-angle light scattering. Together, these approaches allow specimen-specific measurement of tissue stiffness and collagen alignment, which are key factors in determining how the eye responds to mechanical loads. PMID- 29190026 TI - Biolistic Labeling of Retinal Ganglion Cells. AB - Labeling of cellular structures is of fundamental importance in the investigation of diseases of the central nervous system. Biolistic labeling of retinal ganglion cells (RGCs) allows visualization of dendritic and synaptic structures of RGCs in retinal explants from animal models of experimental glaucoma. This technique sparsely labels RGCs, and, due to the stochastic nature of the particle delivery, all RGC types can be potentially observed in the labeled tissue. Quantification of dendritic and synaptic properties permits examination of the specific alterations to RGC morphology at different stages of degeneration, such as dendritic shrinkage and excitatory synapse loss. PMID- 29190027 TI - Anterograde Tract Tracing for Assaying Axonopathy and Transport Deficits in Glaucoma. AB - Whether to stage degeneration or investigate early pathology in glaucoma, examination of axonal structure and function is essential. There are a wide variety of methods available to investigators using animal models of glaucoma, with varying utilities depending on the questions asked. Here, we describe the use of anterograde neuronal tract tracing using cholera toxin B (CTB) for the determination of axon transport integrity of the retinofugal projection. This method reveals the structure of the retinal axons as well as the functional integrity of anterograde transport systems. PMID- 29190028 TI - In Vitro and In Vivo Methods for Studying Retinal Ganglion Cell Survival and Optic Nerve Regeneration. AB - Glaucoma is marked by a progressive degeneration of the optic nerve and delayed loss of retinal ganglion cells (RGCs), the projection neurons of the eye. Because RGCs are not replaced and because surviving RGCs cannot regenerate their axons, the visual loss in glaucoma is largely irreversible. Here, we describe methods to evaluate treatments that may be beneficial for treating glaucoma using in vitro cell culture models (immunopanning to isolate neonatal RGCs, dissociated mature retinal neurons, retinal explants) and in vivo models that test potential treatments or investigate underlying molecular mechanisms in an intact system. Potentially, use of these models can help investigators continue to improve treatments to preserve RGCs and restore visual function in patients with glaucoma.

AB - Accurately characterizing the 3D geometry of the optic nerve head neural and connective tissues has been the goal of a large and important body of scientific work. In the present report, we summarize our methods for the high-resolution, digital, 3D histomorphometric reconstruction of the optic nerve head tissues, including their visualization, parameterization, and quantification. In addition, we present our methods for between-eye comparisons of this anatomy, and their use to determine animal-specific and experiment-wide experimental glaucoma versus Control eye differences in the unilateral, monkey experimental glaucoma model. Finally, we demonstrate its application to finite element modeling, 3D optic nerve head reconstruction of other species, and 3D optic nerve head reconstructions using other imaging modalities. PMID- 29190030 TI - Visualizing Astrocytes of the Optic Nerve. AB - Astrocytes make up approximately 30% of all the cells in the mammalian central nervous system. They are not passive, as once thought, but are integral to brain physiology and perform many functions that are important for normal neuronal development and metabolism, synapse formation, synaptic transmission, and in repair following injury/disease. Astrocytes also communicate with neurons, blood vessels, and other types of glial cells. Astrocytes within the optic nerve head region play a key role in glaucomatous axon degeneration. In this chapter, we describe ways in which astrocytes of the optic nerve head can be visualized, beginning with basic immunohistochemical staining methods, to single-cell dye injections and then to transgenic animals. We will also discuss the pros and cons of each method. Many of the methods were initially developed to visualize brain astrocytes; in some cases, the method has translated well to astrocytes of the optic nerve, and in others, it remains unclear. PMID- 29190031 TI - Investigation of MicroRNA Expression in Experimental Glaucoma. AB - MicroRNAs are small, endogenous noncoding RNAs that modulate post-transcriptional gene expression. Recent evidence suggests that they may have a potential role in the regulation of the complex biological responses that develop in response to elevated intraocular pressure. However, contemporary microRNA assay techniques (e.g., microarrays and next-generation sequencing) typically require large amounts of RNA template that are often times difficult to obtain from glaucomatous tissue. We describe in detail an experimental protocol utilizing targeted pre-amplification and low-density polymerase chain reaction arrays to circumvent this hurdle. This approach optimizes the simultaneous high-throughput screening of small tissue samples, such as the rodent optic nerve head, for up to 754 microRNA probes while also providing an opportunity for subsequent confirmatory reactions of technical or biological replicates. PMID- 29190032 TI - Utilizing RNA-Seq to Identify Differentially Expressed Genes in Glaucoma Model Tissues, Such as the Rodent Optic Nerve Head. AB - Understanding the cellular pathways activated by elevated intraocular pressure (IOP) is crucial for the development of more effective glaucoma treatments. Microarray studies have previously been used to identify several key gene expression changes in early and extensively injured ONH, as well as in the retina. Limitations of microarrays include that they can only be used to detect transcripts that correspond to existing genomic sequencing information and their narrower dynamic range. However, RNA sequencing (RNA-seq) is a powerful tool for investigating known transcripts, as well as for exploring new ones (including noncoding RNAs and small RNAs), is more quantitative, and has the added benefit that the data can be re-analyzed as new sequencing information becomes available. Here, we describe an RNA-seq method specifically developed for identifying differentially expressed genes in optic nerve heads of eyes exposed to elevated intraocular pressure. The methods described here could also be applied to small tissue samples (less than 100 ng in total RNA yield) from retina, optic nerve, or other regions of the central nervous system. PMID- 29190033 TI - Single-Cell Dissociation and Characterization in the Murine Retina and Optic Nerve. AB - Recent technological advances have extended the range of analytic tools to very small samples. It is now possible to assay the transcriptome, and in some cases even the proteome, of single cells reliably. This allows addressing novel questions, such as the genotype/phenotype relationships of single neurons, heterogeneity within individual cells of the same type, or the basis of differential vulnerability to injury. An important prerequisite for these kinds of studies is the ability to isolate well-defined individual cells without contamination by adjacent tissue. In the retina and optic nerve, cells of different types and functions are closely intermingled, limiting the use of standard methods such as laser capture microdissection. Here, we describe a simple method to isolate morphologically intact cells from the retina and the optic nerve and discuss considerations in recognizing and isolating different cell types after dissociation. PMID- 29190035 TI - Impact assessment of projected climate change on diffuse phosphorous loss in Xin'anjiang catchment, China. AB - Diffuse nutrient loss is a serious threat to water security and has severely deteriorated water quality throughout the world. Xin'anjiang catchment, as a main drinking water source for Hangzhou City, has been a national concern for water environment protection with payment for watershed services construction. Detection of diffuse phosphorous (DP) pollution dynamics under climate change is significant for sustainable water quality management. In this study, the impact of projected climate change on DP load was analyzed using SWAT to simulate the future changes of diffuse components (carriers: water discharge and sediment; nutrient: DP) at both station and sub-catchment scales under three climate change scenarios (RCP2.6, RCP4.5, and RCP8.5). Results showed that wetting and warming years were expected with increasing tendencies of both precipitation and temperature in the two future periods (2020s: 2021~2030, 2030s: 2031~2040) except in the 2020s in the RCP2.6 scenario, and the annual average increasing ratios of precipitation and temperature reached - 1.79~3.79% and 0.48~1.27 degrees C, respectively, comparing with those in the baseline (2000s: 2001~2010). Climate change evidently altered annual and monthly average water discharge and sediment load, while it has a remarkable impact on the timing and monthly value of DP load at station scale. DP load tended to increase in the non-flood season at Yuliang due to strengthened nutrient flushing from rice land into rivers with increasing precipitation and enhanced phosphorous cycle in soil layers with increasing temperature, while it tended to decrease in the flood season at Yuliang and in most months at Tunxi due to restricted phosphorous reaction with reduced dissolved oxygen content and enhanced dilution effect. Spatial variability existed in the changes of sediment load and DP load at sub-catchment scale due to climate change. DP load tended to decrease in most sub-catchments and was the most remarkable in the RCP8.5 scenario (2020s, - 9.00~2.63%; 2030s, - 11.16~7.89%), followed by RCP2.6 (2020s, - 10.00~2.90%; 2030s, - 9.00~6.63%) and RCP4.5 (2020s, - 6.81~5.49%, 2030s, - 10.00~9.09%) scenarios. Decreasing of DP load mainly aggregated in the western and eastern mountainous regions, while it tended to increase in the northern and middle regions. This study was expected to provide insights into diffuse nutrient loss control and management in Xin'anjiang catchment, and scientific references for the implementation of water environmental protection in China. PMID- 29190036 TI - Devices for preventing percutaneous exposure injuries caused by needles in healthcare personnel. AB - BACKGROUND: Percutaneous exposure injuries from devices used for blood collection or for injections expose healthcare workers to the risk of blood borne infections such as hepatitis B and C, and human immunodeficiency virus (HIV). Safety features such as shields or retractable needles can possibly contribute to the prevention of these injuries and it is important to evaluate their effectiveness. OBJECTIVES: To determine the benefits and harms of safety medical devices aiming to prevent percutaneous exposure injuries caused by needles in healthcare personnel versus no intervention or alternative interventions. SEARCH METHODS: We searched CENTRAL, MEDLINE, EMBASE, NHSEED, Science Citation Index Expanded, CINAHL, Nioshtic, CISdoc and PsycINFO (until 11 November 2016). SELECTION CRITERIA: We included randomised controlled trials (RCT), controlled before and after studies (CBA) and interrupted time-series (ITS) designs of the effect of safety engineered medical devices on percutaneous exposure injuries in healthcare staff. DATA COLLECTION AND ANALYSIS: Two of the authors independently assessed study eligibility and risk of bias and extracted data. We synthesized study results with a fixed-effect or random-effects model meta-analysis where appropriate. MAIN RESULTS: We included six RCTs with 1838 participants, two cluster-RCTs with 795 participants and 73,454 patient days, five CBAs with approximately 22,000 participants and eleven ITS with an average of 13.8 data points. These studies evaluated safe modifications of blood collection systems, intravenous (IV) systems, injection systems, multiple devices, sharps containers and legislation on the implementation of safe devices. We estimated the needlestick injury (NSI) rate in the control groups to be about one to five NSIs per 1000 person-years. There were only two studies from low- or middle-income countries. The risk of bias was high in 20 of 24 studies. Safe blood collection systems:We found one RCT that found a safety engineered blood gas syringe having no considerable effect on NSIs (Relative Risk (RR) 0.2, 95% Confidence Interval (95% CI) 0.01 to 4.14, 550 patients, very low quality evidence). In one ITS study, safe blood collection systems decreased NSIs immediately after the introduction (effect size (ES) -6.9, 95% CI -9.5 to -4.2) but there was no further decrease over time (ES -1.2, 95% CI -2.5 to 0.1, very low quality evidence). Another ITS study evaluated an outdated recapping shield, which we did not consider further. Safe Intravenous systemsThere was very low quality evidence in two ITS studies that NSIs were reduced with the introduction of safe IV devices, whereas one RCT and one CBA study provided very low quality evidence of no effect. However, there was moderate quality evidence produced by four other RCT studies that these devices increased the number of blood splashes when the safety system had to be engaged actively (relative risk (RR) 1.6, 95% CI 1.08 to 2.36). In contrast there was low quality evidence produced by two RCTs of passive systems that showed no effect on blood splashes. Yet another RCT produced low quality evidence that a different safe active IV system also decreased the incidence of blood leakages. Safe injection devicesThere was very low quality evidence provided by one RCT and one CBA study showing that introduction of safe injection devices did not considerably change the NSI rate. One ITS study produced low quality evidence showing that the introduction of safe passive injection systems had no effect on NSI rate when compared to safe active injection systems. Multiple safe devicesThere was very low quality evidence from one CBA study and two ITS studies. According to the CBA study, the introduction of multiple safe devices resulted in a decrease in NSI,whereas the two ITS studies found no change. Safety containersOne CBA study produced very low quality evidence showing that the introduction of safety containers decreased NSI. However, two ITS studies evaluating the same intervention found inconsistent results. LegislationThere was low to moderate quality evidence in two ITS studies that introduction of legislation on the use of safety-engineered devices reduced the rate of NSIs among healthcare workers. There was also low quality evidence which showed a decrease in the trend over time for NSI rates.Twenty out of 24 studies had a high risk of bias and the lack of evidence of a beneficial effect could be due to both confounding and bias. This does not mean that these devices are not effective. AUTHORS' CONCLUSIONS: For safe blood collection systems, we found very low quality evidence of inconsistent effects on NSIs. For safe passive intravenous systems, we found very low quality evidence of a decrease in NSI and a reduction in the incidence of blood leakage events but moderate quality evidence that active systems may increase exposure to blood. For safe injection needles, the introduction of multiple safety devices or the introduction of sharps containers the evidence was inconsistent or there was no clear evidence of a benefit. There was low to moderate quality evidence that introduction of legislation probably reduces NSI rates.More high-quality cluster-randomised controlled studies that include cost-effectiveness measures are needed, especially in countries where both NSIs and blood-borne infections are highly prevalent. PMID- 29190037 TI - Routine antibiotic prophylaxis after normal vaginal birth for reducing maternal infectious morbidity. AB - BACKGROUND: Infectious morbidities contribute to considerable maternal and perinatal morbidity and mortality, including women at no apparent increased risk of infection. To reduce the incidence of infections, antibiotics are often administered to women after uncomplicated childbirth, particularly in settings where women are at higher risk of puerperal infectious morbidities. OBJECTIVES: To assess whether routine administration of prophylactic antibiotics to women after normal (uncomplicated) vaginal birth, compared with placebo or no antibiotic prophylaxis, reduces postpartum maternal infectious morbidities and improves outcomes. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 August 2017), LILACS, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (22 August 2017) and reference lists of retrieved studies. SELECTION CRITERIA: We planned to include randomised or quasi-randomised trials evaluating the use of prophylactic antibiotics versus placebo or no antibiotic prophylaxis. Trials using a cluster randomised design would have been eligible for inclusion, but we found none.In future updates of this review, we will include studies published in abstract form only, provided sufficient information is available to assess risks of bias. We will consider excluded abstracts for inclusion once the full publication is available, or the authors provide more information.Trials using a cross-over design are not eligible for inclusion in this review. DATA COLLECTION AND ANALYSIS: Two review authors conducted independent assessment of trials for inclusion and risks of bias. They independently extracted data and checked them for accuracy, resolving differences in assessments by discussion. They evaluated methodological quality using standard Cochrane criteria and the GRADE approach.We present the summaries as risk ratios (RRs) and mean difference (MDs) using fixed- or random-effect models. For one primary outcome we found considerable heterogeneity and interaction. We explored further using subgroup analysis to investigate the effects of the randomisation unit. All review authors discussed and interpreted the results. MAIN RESULTS: One randomised controlled trial (RCT) and two quasi-RCTs contributed data on 1779 women who had uncomplicated vaginal births, comparing different antibiotic regimens with placebo or no treatment. The included trials took place in the 1960s (one trial) and 1990s (two trials). The trials were conducted in France, the USA and Brazil. Antibiotics administered included: oral sulphamethoxypyridazine or chloramphenicol for three to five days, and intravenous amoxicillin and clavulanic acid in a single dose one hour after birth. We rated most of the domains for risk of bias as high risk, with the exception of reporting bias and other potential bias.The quality of evidence ranged from low to very low, based on the GRADE quality assessment, given very serious design limitations of the included studies, few events and wide confidence intervals (CIs) of effect estimates.We found a decrease in the risk of endometritis (RR 0.28, 95% CI 0.09 to 0.83, two trials, 1364 women,very low quality). However, one trial reported zero events for this outcome and we rate the evidence as very low quality. There was little or no difference between groups for the risk of urinary tract infection (RR 0.25, 95% CI 0.05 to 1.19, two trials, 1706 women,low quality), wound infection after episiotomy (reported as wound dehiscence in the included trials) (RR 0.78, 95% CI 0.31 to 1.96, two trials, 1364 women, very low quality) and length of maternal hospital stay in days (MD -0.15, 95% CI -0.31 to 0.01, one trial, 1291 women, very low quality). Cost of care in US dollar equivalent was 21/2 times higher in the control group compared to the group receiving antibiotics prophylaxis (USD 3600: USD 9000, one trial, 1291 women). There were few or no differences between treated and control groups for adverse effects of antibiotics (skin rash) reported in one woman in each of the two trials (RR 3.03, 95% CI 0.32 to 28.95, two trials, 1706 women, very low quality). The incidence of severe maternal infectious morbidity, antimicrobial resistance or women's satisfaction with care were not addressed by any of the included studies. AUTHORS' CONCLUSIONS: Routine administration of antibiotics may reduce the risk of endometritis after uncomplicated vaginal birth. The small number and nature of the trials limit the interpretation of the evidence for application in practice, particularly in settings where women may be at higher risk of developing endometritis. The use of antibiotics did not reduce the incidence of urinary tract infections, wound infection or the length of maternal hospital stay. Antibiotics are not a substitute for infection prevention and control measures around the time of childbirth and the postpartum period. The decision to routinely administer prophylactic antibiotics after normal vaginal births needs to be balanced by patient features, childbirth setting and provider experience, including considerations of the contribution of indiscriminate use of antibiotics to raising antimicrobial resistance. Well-designed and high-powered randomised controlled trials would help to evaluate the added value of routine antibiotic administration as a measure to prevent maternal infections after normal vaginal delivery. PMID- 29190034 TI - The role of alphaB-crystallin in skeletal and cardiac muscle tissues. AB - All organisms and cells respond to various stress conditions such as environmental, metabolic, or pathophysiological stress by generally upregulating, among others, the expression and/or activation of a group of proteins called heat shock proteins (HSPs). Among the HSPs, special attention has been devoted to the mutations affecting the function of the alphaB-crystallin (HSPB5), a small heat shock protein (sHsp) playing a critical role in the modulation of several cellular processes related to survival and stress recovery, such as protein degradation, cytoskeletal stabilization, and apoptosis. Because of the emerging role in general health and disease conditions, the main objective of this mini review is to provide a brief account on the role of HSPB5 in mammalian muscle physiopathology. Here, we report the current known state of the regulation and localization of HSPB5 in skeletal and cardiac tissue, making also a critical summary of all human HSPB5 mutations known to be strictly associated to specific skeletal and cardiac diseases, such as desmin-related myopathies (DRM), dilated (DCM) and restrictive (RCM) cardiomyopathy. Finally, pointing to putative strategies for HSPB5-based therapy to prevent or counteract these forms of human muscular disorders. PMID- 29190038 TI - Closure methods of the appendix stump for complications during laparoscopic appendectomy. AB - BACKGROUND: Laparoscopic appendectomy is amongst the most common general surgical procedures performed in the developed world. Arguably, the most critical part of this procedure is effective closure of the appendix stump to prevent catastrophic intra-abdominal complications from a faecal leak into the abdominal cavity. A variety of methods to close the appendix stump are used worldwide; these can be broadly divided into traditional ligatures (such as intracorporeal or extracorporeal ligatures or Roeder loops) and mechanical devices (such as stapling devices, clips, or electrothermal devices). However, the optimal method remains unclear. OBJECTIVES: To compare all surgical techniques now used for appendix stump closure during laparoscopic appendectomy. SEARCH METHODS: In June 2017, we searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 6) in the Cochrane Library, MEDLINE Ovid (1946 to 14 June 2017), Embase Ovid (1974 to 14 June 2017), Science Citation Index - Expanded (14 June 2017), China Biological Medicine Database (CBM), the World Health Organization International Trials Registry Platform search portal, ClinicalTrials.gov, Current Controlled Trials, the Chinese Clinical Trials Register, and the EU Clinical Trials Register (all in June 2017). We searched the reference lists of relevant publications as well as meeting abstracts and Conference Proceedings Citation Index to look for additional relevant clinical trials. SELECTION CRITERIA: We included all randomised controlled trials (RCTs) that compared mechanical appendix stump closure (stapler, clips, or electrothermal devices) versus ligation (Endoloop, Roeder loop, or intracorporeal knot techniques) for uncomplicated appendicitis. DATA COLLECTION AND ANALYSIS: Two review authors identified trials for inclusion, collected data, and assessed risk of bias independently. We performed the meta-analysis using Review Manager 5. We calculated the odds ratio (OR) for dichotomous outcomes and the mean difference (MD) for continuous outcomes, with 95% confidence intervals (CIs). MAIN RESULTS: We included eight randomised studies encompassing 850 participants. Five studies compared titanium clips versus ligature, two studies compared an endoscopic stapler device versus ligature, and one study compared an endoscopic stapler device, titanium clips, and ligature. In our analyses of primary outcomes, we found no differences in total complications (OR 0.97, 95% CI 0.27 to 3.50, 8 RCTs, very low-quality evidence), intraoperative complications (OR 0.93, 95% CI 0.34 to 2.55, 8 RCTs, very low-quality evidence), or postoperative complications (OR 0.80, 95% CI 0.21 to 3.13, 8 RCTs, very low-quality evidence) between ligature and all types of mechanical devices. However, our analyses of secondary outcomes revealed that use of mechanical devices saved approximately nine minutes of total operating time when compared with use of a ligature (mean difference (MD) -9.04 minutes, 95% CI -12.97 to -5.11 minutes, 8 RCTs, very low-quality evidence). However, this finding did not translate into a clinically or statistically significant reduction in inpatient hospital stay (MD 0.02 days, 95% CI -0.12 to 0.17 days, 8 RCTs, very low-quality evidence). Available information was insufficient for reliable comparison of total hospital costs and postoperative pain/quality of life between the two approaches. Overall, evidence across all analyses was of very low quality, with substantial potential for confounding factors. Given the limitations of all studies in terms of bias and the low quality of available evidence, a clear conclusion regarding superiority of any one particular type of mechanical device over another is not possible. AUTHORS' CONCLUSIONS: Evidence is insufficient at present to advocate omission of conventional ligature-based appendix stump closure in favour of any single type of mechanical device over another in uncomplicated appendicitis. PMID- 29190039 TI - Blood cell integrins and diseases. AB - Integrins are adhesion molecules on the surface of cells. In blood cells they are responsible for rapid changes during adhesion of the cell to the endothelium. Deficiency or defective function of integrins will result in severe illnesses. Surprisingly, certain variants of integrins are associated with an increased risk of developing SLE. In autoimmune diseases and as a result of organ transplantations integrins participate in reactions in which leukocytes attack the body's own tissues. This has resulted in the development of drugs in antibody form for inhibition of the action of integrins. These drugs may, however, exhibit severe adverse effects. PMID- 29190040 TI - Baroreflex activation therapy in the treatment of resistant hypertension. AB - Baroreceptors are sensory nerve endings in the carotid sinuses and the aortic arch. Notably, a dysfunction in the autonomic nervous system (sympathetic hyperactivity) has been shown to be part of the pathophysiology of chronic hypertension. Baroreflex activation therapy is an invasive treatment modality to decrease blood pressure by stimulating baroreceptors in the wall of the carotid sinus. Preliminary results of baroreflex activation therapy in resistant hypertension and systolic heart failure have been promising. If its effect can be proven in controlled studies, it may serve as an important new tool in the treatment of patients with resistant hypertension at a high risk of cardiovascular complications. PMID- 29190041 TI - Doppler imaging in inflammatory rheumatic diseases. AB - Doppler imaging has increased in rheumatology during this millennium. The method can detect slow blood flow in inflamed synovium and soft tissues. Doppler imaging is more sensitive than clinical examination in the detection of joint inflammation. Ultrasound imaging combined with Doppler imaging is regarded as reference method in the evaluation of enthesitis,. Doppler imaging is an excellent tool in the diagnostics and follow up in the treatment of the inflammatory rheumatic diseases because it does not use radiation, can be performed bedside and repeated often. The adjustment of ultrasound and Doppler signal is machine specific. PMID- 29190042 TI - Health effects of mindfulness - what should the doctor know? AB - There is solid evidence of the alleviation with mindfulness of chronic pain, symptoms of anxiety and depression and recurrent depression as well as enhancement of immunity. A dose-response relationship has been observed between the amount of practicing mindfulness and alleviation of stress and mood symptoms, and practicing is associated with structural and functional alterations in the brain. Mindfulness interventions are effective and suited for many kinds of human groups. Through increased ability to be present and increased compassion, the doctor's own mindfulness practicing may support the patient-doctor relationship PMID- 29190043 TI - Monitoring of blood glucose level in2016. AB - Self-care of insulin-tretated diabetes has in recent years become considerably more technical. Continuous glucose sensoring, measuring the glucose level of tissue fluid, has become an important tool for the management of glucose values in the everyday life of the diabetic patient. Detailed guidance to the use of the devices is essential in their utilization. The first glucose sensor requiring no calibration though the measurement of blood glucose level has also entered the market. Numerous smartphone applications for self-monitoring have emerged, and cloud services are being increasingly used for mediating data between the patient and the health facility. The Nightscout system makes remote monitoring of diabetic patients possible with a smart device. PMID- 29190044 TI - Liver abscess and sepsis caused by clostridium perfringens. AB - There is usually enough time for identifying the etiology of calculous cholestasis and cholangitis by imaging and laboratory investigations, provided that antimicrobial drug therapy is started immediately after collection of blood cultures and the patient's general condition is good. The situation changes, if the inflammation is caused by Clostridium perfringens, a rare causative agent of severe sepsis and massive intravascular hemolysis. Mortality from the resulting infection and sepsis is as high as over 70%. Quick recognition of the condition, initiation of antimicrobial drug therapy and drainage of a possible focus of infection may save the patient's life. PMID- 29190045 TI - Biomarkers of neutropenic sepsis. AB - Neutropenic sepsis is a common clinical problem in hematological patients receiving intensive chemotherapy. Complications will develop in a minority of these patients. Biomarkers can be used for the recognition of infection as well as to estimate its severity and risk of complications and also to assess treatment response. Experience gained from other patient groups or sepsis patients treated in intensive care units cannot be directly extrapolated to hematological patients. Numerous biomarkers of infections have been investigated in hematological patients, but no optimal marker has been found. C-reactive protein is still the most commonly used biomarker in hematological patients, but procalcitonin may be a real challenger, although more studies are still needed. PMID- 29190046 TI - Relapsing fever. AB - Relapsing fewer is an infection to be considered in the differential diagnosis of an immigrant's febrile illness. It is a severe, tick-borne or body louse-borne infection caused by the relapsing fever associated borrelia species. The body louse-borne infection is in particular encountered in the Horn of Africa region due to poor hygiene, and has during the past year been described in several European countries as imported by refugees coming from this region. Doctors should thus bear relapsing fever in mind as a differential diagnosis in a febrile refugee having recently arrived in Finland. PMID- 29190047 TI - Exosomes in cerebral diseases - novel form of intercellular communication. AB - Exosomes are vesicles bordered by a lipid membrane and containing various molecules. Virtually all cells in the body are able to secrete exosomes that can be carried long distances within the body and are capable of altering the function of the receiving cell by means of the contained molecules. The amount and composition of molecules contained in exosomes have been shown to differ in various diseases, whereby exosomes can be utilized in diagnostic purposes. Furthermore, it may be possible to use exosomes for the treatment of diseases, because they can carry therapeutic molecules in the body. PMID- 29190048 TI - Why is excessive sitting a health risk? AB - Increased epidemiological evidence over the past few years has shown excessive sitting to be a health risk even if recommendations for physical activity are fulfilled. Sitting is an independent health risk for two reasons: sitting and physical activity exhibit poor correlation, and an increase in physical activity does not contribute to all mechanisms underlying the health risks of sitting. During sitting, muscular passivity increases insulin resistance and influences the transport and oxidation of fatty acids in muscular tissue, and acute exercise is not sufficient to restore all changes. Accordingly, adequate everyday physical activity seems to be important for maintaining the signaling pathways affecting insulin sensitivity. PMID- 29190049 TI - Imaging of an acute stroke patient when planning therapy for arterial thrombosis. AB - Intra-arterial thrombectomy is a highly effective mode of treatment for properly selected patients with acute cerebral ischemia. Imaging studies are essential for making a decision on the treatment of acute cerebral infarction. In imaging, a combination of unenhanced CT scan of the head and CT angiography of the carotid and cerebral arteries during one imaging procedure is recommended for all patients coming into the hospital within the time window for thrombectomy, for patients with unclear time of onset of the symptoms and for whom cerebral hemorrhage is excluded as the cause in unenhanced CT scan. This may further be complemented with CT perfusion imaging. In certain acute situations magnetic resonance imaging is also useful. PMID- 29190050 TI - T cells and cancer - why do the killers become exhausted? AB - Nascent tumors are mostly eliminated by the immune system. During carcinogenesis mutated cells find a way to escape from the immune system's surveillance. As the tumor microenvironment evolves it becomes increasingly difficult for T cells to recognize and kill cancer cells. Recently, novel immunological targets have been recognized and potent immunomodulatory drugs discovered in clinical trials. This has resulted in the emergence of immunotherapy as a novel potent therapy for cancer in addition to chemotherapy, targeted therapy, operative therapy and radiotherapy. PMID- 29190051 TI - Headache as symptom of intracranial hemorrhage. AB - The most important signs of danger of a headache patient include exceptionally intense or acute headache, transient loss or progressive impairment of consciousness, and neurological deficit symptoms. These patients are referred to an urgent assessment by a physician. Computed tomography scanning of the head is carried out in the case of suspected hemorrhage of a headache patient. Routine diagnosis employing cerebrospinal fluid analysis can be abandoned when excluding subarachnoid hemorrhage in a patient with headache symptoms, if blood is with certainty not observed in the CT scan of the head and no more than six hours have passed after the onset of the symptom. If subarachnoid hemorrhage is detected, cerebral CT angiography will be performed at the same time and a neurosurgeon consulted about the need of operative treatment. PMID- 29190052 TI - Clinical picture and overall status of newly diagnosed HIV patients at Turku University Hospital in 2013. AB - Our patient material consists of the 12 patients diagnosed during one year. In all cases, sex was the likely mode of transmission, the number of partners having been high for some patients. Some of the cases were originally detected as a result of contact tracing. In two patients the disease had already at the time of diagnosis progressed to the AIDS stage, naturally complicating the initial phase of treatment. In a quarter of our patients the disease could have been discovered earlier from the symptoms of the primary infection, provided that testing had been done. Adherence to treatment in a HIV patient and treatment outcome are usually excellent. PMID- 29190053 TI - Ectopic pregnancy after supracervical hysterectomy. AB - Ectopic pregnancy after hysterectomy is a rare but potentially life-threatening condition. If ovaries are present, ectopic pregnancy should be ruled out in women with acute abdominal pain and history of hysterectomy. Our patient had an ectopic pregnancy six months after supracervical hysterectomy. PMID- 29190054 TI - Cancer of the tongue - early detection improves the prognosis. AB - Approximately 30 to 40% of all patients with tongue cancer still succumb to the disease in five years. Early diagnosis of the disease is of vital importance, because treatment will in that case cause considerably less harm. The diagnosis is confirmed with a histological specimen, which should be taken from every suspicious lesion, and can easily be taken under local anesthesia with a punch. Already when seeking treatment, as many as 25 % of patients with tongue cancer have neck metastases, which influence the prognosis. Heavy use of tobacco and alcohol are the most important risk factors of tongue cancer. PMID- 29190055 TI - Help from habit reversal for supragastric belching. AB - Supragastric belching differs from common gastric belching. It can be detected by 24-hour intra-esophageal impedance monitoring. Belching is seldom the only symptom: reflux symptom is present in 95% and dysphagia in 65% of the patients. In supragastric belching, the air does not come from the stomach but instead from the esophagus. Belching is caused by the patient him/herself swallowing air into the esophagus. This voluntary but unconscious symptom is treated by therapy in which explaining the mechanism of belching for the patient and learning of correct diaphragmatic breathing technique play a central role. Habit reversal is utilized for teaching the patient to react correctly to preemptive symptoms. PMID- 29190056 TI - Gunshot wounds in Finland. AB - On average 200 gunshot wounds are treated in Finland annually. Half of them are caused by firearm accidents, whereas the great majority of fatal wounds are self inflicted. Physicians treating trauma patients should be familiar with the basics of ballistics. In practice, however, a distinction between gunshot wounds caused by handguns and those caused by rifles or shotguns is generally sufficient. Generally accepted guidelines for treating trauma patients are followed, and imaging is used for nearly all patients. Removal of bullets is generally not necessary. Most patients require operative treatment, but in certain cases a non operative approach may be considered. In severe gunshot wounds rapidly administered antibiotics and a sufficiently radical debridement remain the mainstays of treatment. PMID- 29190057 TI - Altered role of the concept of psychopathy in forensic psychiatry. AB - During the early 20th century, psychopathy referred to "borderland states" between normality and mental illness, corresponding to the current personality disorders. In psychiatric assessment, a significant proportion of psychopaths were considered to be not of sound mind, i.e. of diminished responsibility in contemporary language, which in most cases also led to shorter punishments. Psychopathy as diagnosis was abandoned in 1969, after which use has been made of the terms disorders of character and, later on, personality disorders. Nowadays, personality disorders can have a punishment-shortening effect only if they come close to a psychotic disorder. A psychopathy assessed by using current methods may even result in a longer verdict. PMID- 29190058 TI - Diagnosis of nonalcoholic fatty liver disease (NAFLD). AB - Nonalcoholic fatty liver disease (NAFLD) increases mortality from liver and heart disease and is the most important cause of hepatocellular carcinoma (HCC), which is rapidly becoming more common. Those having an increased fibrosis risk, cirrhosis or HCC should be identified amongst those with simple steatosis. Liver enzymes should always be determined at the yearly follow-up of patients with type 2 diabetes and those with the metabolic syndrome. Fatty liver should lead to an assessment of the risk of fibrosis by using a simple fibrosis test and to the referral of patients at risk by a specialist for diagnosis and treatment of NASH and fibrosis. NASH can only be diagnosed using a liver biopsy. PMID- 29190059 TI - Lasers in corneal surgery. AB - New laser methods have introduced new possibilities and partly replaced traditional methods in corneal surgery. Femtosecond lasers have traditionally been used to replace the surgeons' knife in corneal refractive surgery and corneal transplantation. Excimer laser has been used from the beginning of 1990 for the reshaping of cornea. With the development of excimer laser, traditional photorefractive corneal surgery has improved and new methods have been found such as PRK, PTK, epi-LASIK, and LASEK. Today LASIK, the most commonly used refractive surgery, uses both femtosecond and excimer lasers. SMILE, the most recent method in corneal refractive surgery, is solely based on the use of femtosecond laser.

AB - NTRODUCTION: We investigated factors affecting treatment outcome and cost of treatment among adolescents treated for anorexia nervosa in specialized care. METHODS: Records of 47 patients with anorexia nervosa treated at the adolescent eating disorder unit were reviewed retrospectively. RESULTS: Individual differences in the need for treatment and cost of treatment were considerable. Nearly one third of patients required treatment at multiple wards in addition to outpatient care. The majority of costs (76%) incurred from treating a minority (29 %) of patients. Psychiatric comorbidity, particularly depression, was associated with a greater need for treatment and higher costs. CONCLUSIONS: The cost of treatment of anorexia nervosa is considerable, but many of those requiring intensive treatment have a favorable outcome. PMID- 29190064 TI - Investigation of (Leaky) ALD TiO2 Protection Layers for Water-Splitting Photoelectrodes. AB - Protective overlayers for light absorbers in photoelectrochemical water-splitting devices have gained considerable attention in recent years. They stabilize light absorbers which would normally be prone to chemical side reactions leading to degradation of the absorber. Atomic layer deposition (ALD) enables conformal and reproducible ultrathin protective layer growth even on highly structured substrates. One of the most widely investigated protective layers is amorphous TiO2, deposited by ALD at a relatively low temperature (120-150 degrees C). We have deposited protective layers from tetrakis(dimethylamido)titanium(IV) at two different temperatures and investigated their chemical composition as well as optical and electrochemical properties. Our main findings reveal a change in the flat band potential with thickness, reaching a stable value of about -50 to -100 mV versus reversible hydrogen electrode for films >30 nm, with doping densities of ~1020 cm3. Practical thicknesses to achieve pinhole-free films are evaluated and discussed.

AB - On the basis of naphthalene diimide (NDI) units connected to thiophene (T), thienothiophene (TT), or dithienothiophene (DTT) units via a thiophene pi-bridge, three new copolymers-PDTNDI-T, PDTNDI-TT, and PDTNDI-DTT, respectively-were synthesized and used in the fabrication of all-polymer solar cells (all-PSCs). The relationships between the structures of the polymers and their optoelectronic properties and photovoltaic performances as electron acceptors in all-PSCs were investigated in detail. As the number of copolymerized heteroaromatic rings in the DTNDI-based polymers increased, the power conversion efficiencies of the resulting all-PSCs were found to decrease. This decreasing trend in the photovoltaic performance is opposite to the results reported previously for NDI based polymers lacking the thiophene pi-bridge and naphthodithiophene diimide based polymers. In addition, the three polymers were found to exhibit distinct molecular orientations: a face-on orientation for PDTNDI-T and edge-on orientations for PDTNDI-TT and PDTNDI-DTT. Our results indicate that large fused aromatic rings are not necessarily advantageous in the design of NDI-based polymers containing pi-conjugated bridges.

AB - An effective strategy to tailor the microporous structures has been developed based on the shape memory effect in porous poly(l-lactic acid) membranes in which tiny crystals and amorphous matrix play the roles of shape-fixed phase and reversible-phase, respectively. Our results indicate that not only PLLA membranes but micropores exhibit shape memory properties. The proportional deformations on two scales have been achieved by uniaxial or biaxial tension, providing a facile way to manipulate continuously the size and the orientation degree of pores on microscale. The enhanced separation performance has been validated by taking polystyrene colloids with varying diameters as an example. PMID- 29190067 TI - Matrix Sputtering Method: A Novel Physical Approach for Photoluminescent Noble Metal Nanoclusters. AB - Noble metal nanoclusters are believed to be the transition between single metal atoms, which show distinct optical properties, and metal nanoparticles, which show characteristic plasmon absorbance. The interesting properties of these materials emerge when the particle size is well below 2 nm, such as photoluminescence, which has potential application particularly in biomedical fields. These photoluminescent ultrasmall nanoclusters are typically produced by chemical reduction, which limits their practical application because of the inherent toxicity of the reagents used in this method. Thus, alternative strategies are sought, particularly in terms of physical approaches, which are known as "greener alternatives," to produce high-purity materials at high yields. Thus, a new approach using the sputtering technique was developed. This method was initially used to produce thin films using solid substrates; now it can be applied even with liquid substrates such as ionic liquids or polyethylene glycol as long as these liquids have a low vapor pressure. This revolutionary development has opened up new areas of research, particularly for the synthesis of colloidal nanoparticles with dimensions below 10 nm. We are among the first to apply the sputtering technique to the physical synthesis of photoluminescent noble metal nanoclusters. Although typical sputtering systems have relied on the effect of surface composition and viscosity of the liquid matrix on controlling particle diameters, which only resulted in diameters ca. 3-10 nm, that were all plasmonic, our new approach introduced thiol molecules as stabilizers inspired from chemical methods. In the chemical syntheses of metal nanoparticles, controlling the concentration ratio between metal ions and stabilizing reagents is a possible means of systematic size control. However, it was not clear whether this would be applicable in a sputtering system. Our latest results showed that we were able to generically produce a variety of photoluminescent monometallic nanoclusters of Au, Ag, and Cu, all of which showed stable emission in both solution and solid form via our matrix sputtering method with the induction of cationic-, neutral-, and anionic-charged thiol ligands. We also succeeded in synthesizing photoluminescent bimetallic Au-Ag nanoclusters that showed tunable emission within the UV-NIR region by controlling the composition of the atomic ratio by a double-target sputtering technique. Most importantly, we have revealed the formation mechanism of these unique photoluminescent nanoclusters by sputtering, which had relatively larger diameters (ca. 1-3 nm) as determined using TEM and stronger emission quantum yield (max. 16.1%) as compared to typical photoluminescent nanoclusters prepared by chemical means. We believe the high tunability of sputtering systems presented here has significant advantages for creating novel photoluminescent nanoclusters as a complementary strategy to common chemical methods. This Account highlights our journey toward understanding the photophysical properties and formation mechanism of photoluminescent noble metal nanoclusters via the sputtering method, a novel strategy that will contribute widely to the body of scientific knowledge of metal nanoparticles and nanoclusters. PMID- 29190069 TI - Surface-Plasmon-Driven Hot Electron Photochemistry. AB - Visible-light-driven photochemistry has continued to attract heightened interest due to its capacity to efficiently harvest solar energy and its potential to solve the global energy crisis. Plasmonic nanostructures boast broadly tunable optical properties coupled with catalytically active surfaces that offer a unique opportunity for solar photochemistry. Resonant optical excitation of surface plasmons produces energetic hot electrons that can be collected to facilitate chemical reactions. This review sums up recent theoretical and experimental approaches for understanding the underlying photophysical processes in hot electron generation and discusses various electron-transfer models on both plasmonic metal nanostructures and plasmonic metal/semiconductor heterostructures. Following that are highlights of recent examples of plasmon driven hot electron photochemical reactions within the context of both cases. The review concludes with a discussion about the remaining challenges in the field and future opportunities for addressing the low reaction efficiencies in hot electron-induced photochemistry. PMID- 29190068 TI - Structural and Functional Basis for Targeting Campylobacter jejuni Agmatine Deiminase To Overcome Antibiotic Resistance. AB - Campylobacter jejuni is the most common bacterial cause of gastroenteritis and a major contributor to infant mortality in the developing world. The increasing incidence of antibiotic-resistant C. jejuni only adds to the urgency to develop effective therapies. Because of the essential role that polyamines play, particularly in protection from oxidative stress, enzymes involved in the biosynthesis of these metabolites are emerging as promising antibiotic targets. The recent description of an alternative pathway for polyamine synthesis, distinct from that in human cells, in C. jejuni suggests this pathway could be a target for novel therapies. To that end, we determined X-ray crystal structures of C. jejuni agmatine deiminase (CjADI) and demonstrated that loss of CjADI function contributes to antibiotic sensitivity, likely because of polyamine starvation. The structures provide details of key molecular features of the active site of this protein. Comparison of the unliganded structure (2.1 A resolution) to that of the CjADI-agmatine complex (2.5 A) reveals significant structural rearrangements that occur upon substrate binding. The shift of two helical regions of the protein and a large conformational change in a loop near the active site generate a narrow binding pocket around the bound substrate. This change optimally positions the substrate for catalysis. In addition, kinetic analysis of this enzyme demonstrates that CjADI is an iminohydrolase that effectively deiminates agmatine. Our data suggest that C. jejuni agmatine deiminase is a potentially important target for combatting antibiotic resistance, and these results provide a valuable framework for guiding future drug development.

AB - The quasi-one-dimensional (1D) metallic conductivity of the perovskite-related SrnNbnO3n+2 compounds is of continuing fundamental physical interest as well as being important for developing advanced electronic devices. The SrnNbnO3n+2 compounds can be derived by introducing additional oxygen into the SrNbO3 perovskite. However, the physical origin for the transition of electrical properties from the three-dimensional (3D) isotropic conductivity in SrNbO3 to the quasi-1D metallic conductivity in SrnNbnO3n+2 requires more in-depth clarification. Here we combine advanced transmission electron microscopy with atomistic first-principles calculations to unambiguously determine the atomic and electronic structures of the SrnNbnO3n+2 compounds and reveal the underlying mechanism for their quasi-1D metallic conductivity. We demonstrate that the local electrical conductivity in the SrnNbnO3n+2 compounds directly depends on the configuration of the NbO6 octahedra in local regions. These findings will shed light on the realization of two-dimensional (2D) electrical conductivity from a bulk material, namely by segmenting a 3D conductor into a stack of 2D conducting thin layers. PMID- 29190072 TI - Quantification of DNA in Neonatal Dried Blood Spots by Adenine Tandem Mass Spectrometry. AB - Newborn screening programs have expanded to include molecular-based assays as first-tier tests and the success of these assays depends on the quality and yield of DNA extracted from neonatal dried blood spots (DBS). To meet high throughput and rapid turnaround time requirements, newborn screening laboratories adopted rapid DNA extraction methods that produce crude extracts. Quantification of DNA in neonatal DBS is not routinely performed due to technical challenges; however, this may enhance the performance of assays that are sensitive to amounts of input DNA. In this study, we developed a novel high throughput method to quantify total DNA in DBS. It is based on specific acid-catalyzed depurination of DNA followed by mass spectrometric quantification of adenine. The amount of adenine was used to calculate DNA quantity per 3.2 mm DBS. Reference intervals were established using archived, neonatal DBS (n = 501) and a median of 130.6 ng of DNA per DBS was obtained, which is in agreement with literature values. The intra- and interday variations were <15%. The limits of detection and quantification were 12.5 and 37.8 nmol/L adenine, respectively. We demonstrated that DNA from neonatal DBS can be successfully quantified in high throughput settings using instruments currently deployed in NBS laboratories.

PMID- 29190074 TI - Carbon Nanotube Embedded Nanostructure for Biometrics. AB - Low electric energy loss is a very important problem to minimize the decay of transferred energy intensity due to impedance mismatch. This issue has been dealt with by adding an impedance matching layer at the interface between two media. A strategy was proposed to improve the charge transfer from the human body to a biometric device by using an impedance matching nanostructure. Nanocomposite pattern arrays were fabricated with shape memory polymer and carbon nanotubes. The shape recovery ability of the nanopatterns enhanced durability and sustainability of the structure. It was found that the composite nanopatterns improved the current transfer by two times compared with the nonpatterned composite sample. The underlying mechanism of the enhanced charge transport was understood by carrying out a numerical simulation. We anticipate that this study can provide a new pathway for developing advanced biometric devices with high sensitivity to biological information. PMID- 29190075 TI - Supramolecularly Caged Green-Emitting Ionic Ir(III)-Based Complex with Fluorinated C^N Ligands and Its Application in Light-Emitting Electrochemical Cells. AB - Ionic Ir(III) complexes are the most promising emitters in light emitting electrochemical cells (LECs), especially in the high energy emission range for which it is difficult to find emitters with sufficient efficiencies and lifetimes. To overcome this challenge, we introduced the concept of intramolecular pi-pi stacking of an ancillary ligand (6-phenyl-2,2'-bipyridine, pbpy) in the design of a new green-emitting iridium ionic transition metal complex with a fluoro-substituted cyclometallated ligand, 2-(4 fluorophenyl)pyridinato (4Fppy). [Ir(4Fppy)2(pbpy)][PF6] has been synthesized and characterized and its photophysical and electrochemical properties have been studied. The complex emits green light with maxima at 561 and 556 nm under UV excitation from powder and thin film, respectively, and displays a high photoluminescence quantum yield (PLQY) of 78.5%. [Ir(4Fppy)2(pbpy)][PF6] based LECs driven under pulsed current conditions showed under an average current density of 100 A m-2 (at 50% duty cycle) a maximum luminance of 1443 cd m-2, resulting in 14.4 cd A-1 and 7.4 lm W-1 current and power efficiencies, respectively. A remarkable long device lifetime of 214 h was observed. Reducing the average current density to 18.5 A m-2 (at 75% duty cycle) led to an exceptional device performance of 19.3 cd A-1 and 14.4 lm W1- for current and power efficiencies, an initial maximum luminance of 352 cd m-2 and a lifetime of 617 h. PMID- 29190076 TI - A Reversible, Charge-Induced Intramolecular C4a-S-Cysteinyl-Flavin in Choline Oxidase Variant S101C. AB - Choline oxidase serves as a paradigm for alcohol oxidation catalyzed by flavin dependent enzymes. In its active site, S101 is 4 A from the flavin C4a atom on an extended loop. Enzyme variants substituted at S101 were generated in a previous study and investigated mechanistically [Yuan, H., and Gadda, G. (2011) Biochemistry 50, 770-779]. In this study, the typical ultraviolet-visible (UV vis) absorption spectrum of oxidized flavin was observed for the S101C enzyme in HEPES, TES, or sodium phosphate, whereas an absorption spectrum suggesting the presence of a C4a-flavin adduct with cysteine was obtained in Tris-HCl at pH 8.0. pH titrations of the UV-vis absorption spectrum of the wild-type, S101A, S101C, and H99N enzymes in the presence and absence of Tris allowed for the determination of two pKa values that define a pH range in which the C4a-S cysteinyl flavin is stabilized. Inhibition studies and stopped-flow kinetics demonstrated that binding of protonated Tris in the active site of the S101C enzyme is required to form the C4a-S-cysteinyl flavin. Deuterium kinetic isotope effects and proton inventories of the S101C enzyme mixed in a stopped-flow spectrophotometer with Tris established a mechanism for the reversible formation of the C4a-S-cysteinyl flavin. This study provides a detailed mechanistic analysis of the reversible formation of a bicovalent C4a-S-cysteinyl-8alpha-N3 histidyl flavin in choline oxidase, identifying an optimal pH range and a mechanistic rationale for the stabilization of de novo C4a-S-cysteinyl-flavins. Moreover, it presents an example of an intramolecular reaction of an enzyme-bound flavin without a substrate. PMID- 29190077 TI - Evaluation of Matrix Metalloproteinase Inhibition by Peptide Microarray-Based Fluorescence Assay on Polymer Brush Substrate and in Vivo Assessment. AB - Matrix metalloproteinases (MMPs) are important biomarkers and potential therapeutic targets of tumor. In this report, a peptide microarray-based fluorescence assay is developed for MMPs inhibitors evaluation through immobilization of biotin-modified peptides on the poly(glycidyl methacrylate-co-2 hydroxyethyl methacrylate) (P(GMA-HEMA)) brush-modified glass slides. After biotin is recognized with cyanine 3 (Cy3)-modified avidin (Cy3-avidin), the microarrays can produce strong fluorescence signal. The biotin moieties detach from microarray, when the biotin-modified peptide substrates are specially cleaved by a MMP, resulting in decreased fluorescence intensity of the microarray. The decreasing level of fluorescence intensity is correlated with the MMP inhibition. Nine known MMP inhibitors against MMP-2 and MMP-9 are evaluated by the assay, and the quantitative determination of inhibitory potencies (half maximal inhibitory concentration) are obtained, which are comparable with the literatures. Two biocompatible fluorogenic peptides containing MMP-specific recognition sequences and FAM/Dabcyl fluorophore-quencher pair are designed as activatable reporter probes for sensing MMP-2 and MMP-9 activities in cell and in vivo. The peptide microarray-based results are well verified by the cell inhibition assay and in vitro fluorescence imaging, and further confirmed by the in vivo imaging of HT-1080 tumor-bearing mice.

AB - Scheelite- and powellite-related materials doped with trivalent lanthanides or actinides have been the subject of extensive research due to their important role in mineralogical, technological, and environmental implications. Detailed structural knowledge of these solid solutions is essential for understanding their physicochemical properties and predicting material properties. In this work, we conduct a comprehensive spectroscopic analysis by means of polarization dependent site-selective time-resolved laser-induced fluorescence spectroscopy, to delineate the influence of the host phase cations for a series of scheelite type matrixes based on a general formula of ABO4 (A = Ca2+, Sr2+, Ba2+; B = W6+, Mo6+) on the local environment of the Eu3+ dopant. Eu3+ has been used as a luminescent probe to access the local structural environment of crystalline substitutional sites suitable for trivalent lanthanide or actinide occupation. Our results show that the lattice distortion is overall minor, but increases with increasing mismatch of host and guest cation size. We observe a linear dependence of Eu3+'s excitation energy on the host cation size and the A-O bond distance, which can be used to determine the hitherto unknown Eu-O bond distance in NaEu(WO4)2. A value of 2.510 A was determined, somewhat larger than a previously reported number for NaEu(MoO4)2. The results also show clear evidence that the local coordination environment of Eu3+ in WO42- materials is more symmetrical than in their isostructural MoO42- counterparts. The detailed spectroscopic interpretation conducted in this study resolves the relation between local distortion around a dopant and the host phase cations in structural disordered materials and may give novel insights with respect to rational design and tailoring of functional materials. PMID- 29190078 TI - Cu(II) Binding to the Peptide Ala-His-His, a Chimera of the Canonical Cu(II) Binding Motifs Xxx-His and Xxx-Zzz-His. AB - Peptides and proteins with the N-terminal motifs NH2-Xxx-His and NH2-Xxx-Zzz-His form well-established Cu(II) complexes. The canonical peptides are Gly-His-Lys and Asp-Ala-His-Lys (from the wound healing factor and human serum albumin, respectively). Cu(II) is bound to NH2-Xxx-His via three nitrogens from the peptide and an external ligand in the equatorial plane (called 3N form here). In contrast, Cu(II) is bound to NH2-Xxx-Zzz-His via four nitrogens from the peptide in the equatorial plane (called 4N form here). These two motifs are not mutually exclusive, as the peptides with the sequence NH2-Xxx-His-His contain both of them. However, this chimera has never been fully explored. In this work, we use a multispectroscopic approach to analyze the Cu(II) binding to the chimeric peptide Ala-His-His (AHH). AHH is capable of forming the 3N- and 4N-type complexes in a pH dependent manner. The 3N form predominates at pH ~ 4-6.5 and the 4N form at ~ pH 6.5-10. NMR experiments showed that at pH 8.5, where Cu(II) is almost exclusively bound in the 4N form, the Cu(II)-exchange between AHH or the amidated AHH-NH2 is fast, in comparison to the nonchimeric 4N form (AAH). Together, the results show that the chimeric AHH can access both Cu(II) coordination types, that minor changes in the second (or further) coordination sphere can impact considerably the equilibrium between the forms, and that Cu kinetic exchange is fast even when Cu-AHH is mainly in the 4N form.

AB - The impact of the {Ru(acac)2} (acac- = acetylacetonate) framework on the transformations of C-H and C-H/C-C bonds of coordinated beta-diketiminate and ketodiimine scaffolds, respectively, has been addressed. It includes the following transformations involving {Ru(acac)2} coordinated beta-diketiminate in 1 and ketodiimine in 2 with the simultaneous change in metal oxidation state: (i) insertion of oxygen into the C(sp2)-H bond of beta-diketiminate in 1, leading to the metalated ketodiimine in 2 and (ii) Bronsted acid (CH3COOH) assisted cleavage of unstrained C(sp2)-C(sp2)/C?N bonds of chelated ketodiimine (2) with the concomitant formation of intramolecular C-N bond in 3, as well as insertion of oxygen into the C(sp3)-H bond of 2 to yield -CHO function in 4 (-CH3 -> -CHO). The aforesaid transformation processes have been authenticated via structural elucidation of representative complexes and spectroscopic and electrochemical investigations. PMID- 29190081 TI - Suppression of Magnetic Quantum Tunneling in a Chiral Single-Molecule Magnet by Ferromagnetic Interactions. AB - Single-molecule magnets (SMMs) retain a magnetization without applied magnetic field for a decent time due to an energy barrier U for spin-reversal. Despite the success to increase U, the difficult to control magnetic quantum tunneling often leads to a decreased effective barrier Ueff and a fast relaxation. Here, we demonstrate the influence of the exchange coupling on the tunneling probability in two heptanuclear SMMs hosting the same spin-system with the same high spin ground state St = 21/2. A chirality-induced symmetry reduction leads to a switch of the MnIII-MnIII exchange from antiferromagnetic in the achiral SMM [MnIII6CrIII]3+ to ferromagnetic in the new chiral SMM RR[MnIII6CrIII]3+. Multispin Hamiltonian analysis by full-matrix diagonalization demonstrates that the ferromagnetic interactions in RR[MnIII6CrIII]3+ enforce a well-defined St = 21/2 ground state with substantially less mixing of MS substates in contrast to [MnIII6CrIII]3+ and no tunneling pathways below the top of the energy barrier. This is experimentally verified as Ueff is smaller than the calculated energy barrier U in [MnIII6CrIII]3+ due to tunneling pathways, whereas Ueff equals U in RR[MnIII6CrIII]3+ demonstrating the absence of quantum tunneling. PMID- 29190083 TI - Structure-Based Design of 6-Chloro-4-aminoquinazoline-2-carboxamide Derivatives as Potent and Selective p21-Activated Kinase 4 (PAK4) Inhibitors. AB - Herein, we report the discovery and characterization of a novel class of PAK4 inhibitors with a quinazoline scaffold. Based on the shape and chemical composition of the ATP-binding pocket of PAKs, we chose a 2,4-diaminoquinazoline series of inhibitors as a starting point. Guided by X-ray crystallography and a structure-based drug design (SBDD) approach, a series of novel 4-aminoquinazoline 2-carboxamide PAK4 inhibitors were designed and synthesized. The inhibitors' selectivity, therapeutic potency, and pharmaceutical properties were optimized. One of the best compounds, 31 (CZh226), showed remarkable PAK4 selectivity (346 fold vs PAK1) and favorable kinase selectivity profile. Moreover, this compound potently inhibited the migration and invasion of A549 tumor cells by regulating the PAK4-directed downstream signaling pathways in vitro. Taken together, these data support the further development of 31 as a lead compound for PAK4-targeted anticancer drug discovery and as a valuable research probe for the further biological investigation of group II PAKs.

AB - Protein-based "hole" hopping typically involves spatially arranged redox-active tryptophan or tyrosine residues. Thermodynamic information is scarce for this type of process. The well-structured alpha3W model protein was studied by protein film square wave voltammetry and transient absorption spectroscopy to obtain a comprehensive thermodynamic and kinetic description of a buried tryptophan residue. A Pourbaix diagram, correlating thermodynamic potentials (E degrees ') with pH, is reported for W32 in alpha3W and compared to equivalent data recently presented for Y32 in alpha3Y ( Ravichandran , K. R. ; Zong , A. B. ; Taguchi , A. T. ; Nocera , D. G. ; Stubbe , J. ; Tommos , C. J. Am. Chem. Soc. 2017 , 139 , 2994 - 3004 ). The alpha3W Pourbaix diagram displays a pKOX of 3.4, a E degrees '(W32(N*+/NH)) of 1293 mV, and a E degrees '(W32(N*/NH); pH 7.0) of 1095 +/- 4 mV versus the normal hydrogen electrode. W32(N*/NH) is 109 +/- 4 mV more oxidizing than Y32(O*/OH) at pH 5.4-10. In the voltammetry measurements, W32 oxidation reduction occurs on a time scale of about 4 ms and is coupled to the release and subsequent uptake of one full proton to and from bulk. Kinetic analysis further shows that W32 oxidation likely involves pre-equilibrium electron transfer followed by proton transfer to a water or small water cluster as the primary acceptor. A well-resolved absorption spectrum of W32* is presented, and analysis of decay kinetics show that W32* persists ~104 times longer than aqueous W* due to significant stabilization by the protein. The redox characteristics of W32 and Y32 are discussed relative to global and local protein properties. PMID- 29190084 TI - Acovenoside A Induces Mitotic Catastrophe Followed by Apoptosis in Non-Small-Cell Lung Cancer Cells. AB - We investigated the cytotoxic potential of the cardenolide glycoside acovenoside A against non-small-cell lung cancer cells. Lung cancer is the leading cause of cancer-related mortality and the second most common cancer diagnosed. Epidemiological studies revealed a direct correlation between the regular administration of cardiac glycosides and a lower incidence of various cancers. Acovenoside A, isolated from the pericarps of Acokanthera oppositifolia, potently inhibited proliferation and induced cytotoxicity in A549 non-small-cell lung cancer cells with an IC50 of 68 +/- 3 nM after 48 h of exposure. Compared to the antineoplastic agent doxorubicin, acovenoside A was more potent in inhibiting the viability of A549 cancer cells. Moreover, acovenoside A exhibited selectivity against cancer cells, being significantly less toxic to lung fibroblasts and nontoxic for peripheral blood mononuclear cells. Analysis of the cell cycle profile in acovenoside A-treated A549 cells revealed mitotic arrest, due to accumulation of the G2/M regulators cyclin B1 and CDK1, and cytokinesis failure. Furthermore, acovenoside A affected the mitochondrial membrane integrity and induced production of radical oxygen species, which resulted in induction of canonical apoptosis, manifested by caspase 3 activation and DNA fragmentation. Based on our results, acovenoside A warrants further exploration as a potential anticancer lead. PMID- 29190085 TI - High-Confidence Protein-Ligand Complex Modeling by NMR-Guided Docking Enables Early Hit Optimization. AB - Structure-based drug design is an integral part of modern day drug discovery and requires detailed structural characterization of protein-ligand interactions, which is most commonly performed by X-ray crystallography. However, the success rate of generating these costructures is often variable, in particular when working with dynamic proteins or weakly binding ligands. As a result, structural information is not routinely obtained in these scenarios, and ligand optimization is challenging or not pursued at all, representing a substantial limitation in chemical scaffolds and diversity. To overcome this impediment, we have developed a robust NMR restraint guided docking protocol to generate high-quality models of protein-ligand complexes. By combining the use of highly methyl-labeled protein with experimentally determined intermolecular distances, a comprehensive set of protein-ligand distances is generated which then drives the docking process and enables the determination of the correct ligand conformation in the bound state. For the first time, the utility and performance of such a method is fully demonstrated by employing the generated models for the successful, prospective optimization of crystallographically intractable fragment hits into more potent binders. PMID- 29190087 TI - Task-Specific Scoring Functions for Predicting Ligand Binding Poses and Affinity and for Screening Enrichment. AB - Molecular docking, scoring, and virtual screening play an increasingly important role in computer-aided drug discovery. Scoring functions (SFs) are typically employed to predict the binding conformation (docking task), binding affinity (scoring task), and binary activity level (screening task) of ligands against a critical protein target in a disease's pathway. In most molecular docking software packages available today, a generic binding affinity-based (BA-based) SF is invoked for all three tasks to solve three different, but related, prediction problems. The limited predictive accuracies of such SFs in these three tasks has been a major roadblock toward cost-effective drug discovery. Therefore, in this work, we develop BT-Score, an ensemble machine-learning (ML) SF of boosted decision trees and thousands of predictive descriptors to estimate BA. BT-Score reproduced BA of out-of-sample test complexes with correlation of 0.825. Even with this high accuracy in the scoring task, we demonstrate that the docking and screening performance of BT-Score and other BA-based SFs is far from ideal. This has motivated us to build two task-specific ML SFs for the docking and screening problems. We propose BT-Dock, a boosted-tree ensemble model trained on a large number of native and computer-generated ligand conformations and optimized to predict binding poses explicitly. This model has shown an average improvement of 25% over its BA-based counterparts in different ligand pose prediction scenarios. Similar improvement has also been obtained by our screening-based SF, BT-Screen, which directly models the ligand activity labeling task as a classification problem. BT-Screen is trained on thousands of active and inactive protein-ligand complexes to optimize it for finding real actives from databases of ligands not seen in its training set. In addition to the three task-specific SFs, we propose a novel multi-task deep neural network (MT-Net) that is trained on data from the three tasks to simultaneously predict binding poses, affinities, and activity levels. We show that the performance of MT-Net is superior to conventional SFs and on a par with or better than models based on single-task neural networks.

AB - Nucleobase radicals are the major intermediates generated by the direct (e.g., dA*+) and indirect (e.g., dA*) effects of gamma-radiolysis. dA* was independently generated in DNA for the first time. The dA*+/dA* equilibrium, and consequently the reactivity in DNA, is significantly shifted toward the radical cation by a flanking dA. Tandem lesions emanating from dA* are the major products when the reactive intermediate is flanked by a 5'-dGT. In contrast, when dA* is flanked by dA, the increased dA*+ pKa results in DNA damage arising from hole transfer. This is the first demonstration that sequence effects lead to the intersection of the direct and indirect effects of ionizing radiation. PMID- 29190088 TI - Highly Effective Polyphosphate Synthesis, Phosphate Removal, and Concentration Using Engineered Environmental Bacteria Based on a Simple Solo Medium-Copy Plasmid Strategy. AB - Microbial polyphosphate (polyP) production is vital to the removal of phosphate from wastewater. However, to date, engineered polyP synthesis using genetically accessible environmental bacteria remains a challenge. This study develops a simple solo medium-copy plasmid-based polyphosphate kinase (PPK1) overexpression strategy for achieving maximum intracellular polyphosphate accumulation by environmental bacteria. The polyP content of the subsequently engineered Citrobacter freundii (CPP) could reach as high as 12.7% of its dry weight. The biomass yield of CPP was also guaranteed because of negligible metabolic burden effects resulting from the medium plasmid copy number. Consequently, substantial removal of phosphate (Pi) from the ambient environment was achieved simultaneously. Because of the need for exogenous Pi for in vivo ATP regeneration, CPP could thoroughly remove Pi from synthetic municipal wastewater when it was applied for the "one-step" removal of Pi with a bench-scale sequence batch membrane reactor. Almost all the phosphorus except for that assimilated by CPP for cellular growth could be recovered in the form of more concentrated Pi. Overall, engineering environmental bacteria to overexpress PPK1 via a solo medium copy plasmid strategy may represent a valuable general option for not only biotechnological research based on sufficient intracellular polyP production but also removal of Pi from wastewater and Pi enrichment.

PMID- 29190090 TI - External Exposure to Short- and Medium-Chain Chlorinated Paraffins for the General Population in Beijing, China. AB - Chlorinated paraffins (CPs) are a class of compounds that are currently produced and used in large amounts in commercial products worldwide. In this study, food, indoor air, indoor dust, and drinking water samples were collected to evaluate the external exposure levels of CPs and possible pathway for the general population in Beijing, China. Short chain CPs (SCCPs) and medium chain CPs (MCCPs) in 199 samples were analyzed using a gas chromatography tandem time-of flight high-resolution mass spectrometry (GC-TOF-HR-MS) method. High levels of CPs were observed in the indoor environment from residential houses, offices, and student dormitories. The geometric mean concentrations (GM) of ?SCCPs and ?MCCPs in indoor dust were 92 MUg g-1 and 82 MUg g-1, respectively, while in indoor air, the concentrations were 80 ng m-3 and 3.4 ng m-3, respectively. The GM of ?SCCPs and ?MCCPs in the diet were 83 ng g-1 dry weight (dw) and 56 ng g-1 dw, respectively. The most important external exposure routes to CPs to the general populations in Beijing were food intake and indoor dust ingestion. Indoor dust and indoor air posed higher risks for toddlers and infants than for adults. PMID- 29190091 TI - Pathways for Concerted [2 + 2] Cycloaddition to Cumulenes. AB - A computational search has revealed concerted pathways for [2 + 2] cycloaddition of ethylene to all 10 of the cumulenes with the formula X?C?Y, where X, Y = C, N, O, and S. Four different concerted pathways have been found, three of them pseudopericyclic plus another based on sp-hybridized carbon. In the case of 2 of the 16 possible cycloadditions, a pair of novel three-membered ring intermediates has been discovered. As simple model reactions, cycloaddition of ethylene to formaldehyde, thioformaldehyde, and formaldimine is also described.

AB - Histone deacetylases (HDACs) are important modulators of epigenetic gene regulation and additionally control the activity of non-histone protein substrates. While for HDACs 1-3 and 6 many potent selective inhibitors have been obtained, for other subtypes much less is known on selective inhibitors and the consequences of their inhibition. The present report describes the development of substituted benzhydroxamic acids as potent and selective HDAC8 inhibitors. Docking studies using available crystal structures have been used for structure based optimization of this series of compounds. Within this study, we have investigated the role of HDAC8 in the proliferation of cancer cells and optimized hits for potency and selectivity, both in vitro and in cell culture. The combination of structure-based design, synthesis, and in vitro screening to cellular testing resulted in potent and selective HDAC8 inhibitors that showed anti-neuroblastoma activity in cellular testing. PMID- 29190093 TI - cis-Dioxorhenium(V/VI) Complexes Supported by Neutral Tetradentate N4 Ligands. Synthesis, Characterization, and Spectroscopy. AB - A series of cis-dioxorhenium(V) complexes containing chiral tetradentate N4 ligands, including cis-[ReV(O)2(pyxn)]+ (1; pyxn = N,N'-dimethyl-N,N'-bis(2 pyridylmethyl)cyclohexane-1,2-diamine), cis-[ReV(O)2(6-Me2pyxn)]+ (cis-2), cis [ReV(O)2(R,R-pdp)]+ (3; R,R-pdp = 1,1'-bis((R,R)-2-pyridinylmethyl)-2,2' bipyrrolidine), cis-[ReV(O)2(R,R-6-Me2pdp)]+ (4), and cis-[ReV(O)2(bqcn)]+ (5; bqcn = N,N'-dimethyl-N,N'-di(quinolin-8-yl)cyclohexane-1,2-diamine), were synthesized. Their structures were established by X-ray crystallography, showing Re-O distances in the range of 1.740(3)-1.769(8) A and O-Re-O angles of 121.4(2) 124.8(4) degrees . Their cyclic voltammograms in MeCN (0.1 M [NBu4]PF6) display a reversible ReVI/V couple at E1/2 = 0.39-0.49 V vs SCE. In aqueous media, three proton-coupled electron transfer reactions corresponding to ReVI/V, ReV/III, and ReIII/II couples were observed at pH 1. The Pourbaix diagrams of 1.OTf, 3.OTf, and 5.OTf have been examined. The electronic absorption spectra of the cis dioxorhenium(V) complexes show three absorption bands at around 800 nm (600-1730 dm3 mol-1 cm-1), 580 nm (1700-5580 dm3 mol-1 cm-1), and 462-523 nm (3170-6000 dm3 mol-1 cm-1). Reaction of 1 with Lewis acids (or protic acids) gave cis [ReV(O)(OH)(pyxn)]2+ (1.H+), in which the Re-O distances are lengthened to 1.788(5) A. Complex cis-2 resulted from isomerization of trans-2 at elevated temperature. cis-[ReVI(O)2(pyxn)](PF6)2 (1'.(PF6)2) was obtained by constant potential electrolysis of 1.PF6 in MeCN (0.1 M [NBu4]PF6) at 0.56 V vs SCE; it displays shorter Re-O distances (1.722(4), 1.726(4) A) and a smaller O-Re-O angle (114.88(18) degrees ) relative to 1 and shows a d-d transition absorption band at 591 nm (epsilon = 77 dm3 mol-1 cm-1). With a driving force of ca. 75 kcal mol-1, 1' oxidizes hydrocarbons with weak C-H bonds (75.5-76.3 kcal mol-1) via hydrogen atom abstraction. DFT and TDDFT calculations on the electronic structures and spectroscopic properties of the cis-dioxorhenium(V/VI) complexes were performed. PMID- 29190094 TI - Active Glucocorticoids Have a Range of Important Adverse Developmental and Physiological Effects on Developing Zebrafish Embryos. AB - Glucocorticoids in aquatic systems originating from natural excretion and medical use may pose a risk to fish. Here, we analyzed physiological and transcriptional effects of clobetasol propionate (CLO), cortisol and cortisone in zebrafish embryos as single compounds and binary mixtures. CLO and cortisol, but not cortisone showed a concentration-dependent decrease in muscle contraction, increase in heart rate, and accelerated hatching. CLO also induced immobilization and edema at high concentrations. Transcription analysis covering up to 26 genes showed that mostly genes related to glucose metabolism, immune system and development were differentially expressed at 91 ng/L and higher. CLO showed stronger effects on immune system genes than cortisol, which was characterized by upregulation of fkbp5, irg1l, gilz, and socs3, and development genes, matrix metalloproteinases mmp-9 and mmp-13, while cortisol led to stronger upregulation of the gluconeogenesis genes g6pca and pepck1. CLO also induced genes regulating the circadian rhythm, nr1d1 and per1a. In contrast, cortisone led to down regulation of vitellogenin. Binary mixtures of cortisol and CLO mostly showed a similar activity as CLO alone on physiological and transcriptional end points but additive effects in heart rate and pepck1 upregulation, which indicates that mixtures of glucocorticoids may be of concern for developing fish. PMID- 29190096 TI - Anisotropy in Time-Resolved Photoelectron Spectroscopy in the Gas Phase. AB - Transient absorption anisotropy is a well-established technique in time-resolved liquid phase spectroscopy. Here, we show how the technique is applied in the gas phase for time-resolved photoelectron spectroscopy and what type of additional information can be obtained as compared to other techniques. We exemplify its use by presenting results on rotational revivals in pyrazine after excitation at 324 nm and provide new insights into two recent experiments: (i) the difference between Rydberg and valence state excitation after one- and two-photon absorption in butadiene and (ii) excitation to the two lowest lying vibronic modes of the degenerate pi3p Rydberg state in 1-azabicyclo[2.2.0]octane. Going forward, we expect the technique to be used on a regular basis, especially with the advent of high harmonic probe sources and liquid beam setups where other techniques to extract polarization-dependent information such as velocity map imaging cannot easily be applied. PMID- 29190097 TI - Stick-Slip Instabilities for Interfacial Chemical Bond-Induced Friction at the Nanoscale. AB - Earthquakes are generally caused by unstable stick-slip motion of faults. This stick-slip phenomenon, along with other frictional properties of materials at the macroscale, is well-described by empirical rate and state friction (RSF) laws. Here we study stick-slip behavior for nanoscale single-asperity silica-silica contacts in atomic force microscopy experiments. The stick-slip is quasiperiodic, and both the amplitude and spatial period of stick-slip increase with normal load and decrease with the loading point (i.e., scanning) velocity. The peak force prior to each slip increases with the temporal period logarithmically, and decreases with velocity logarithmically, consistent with stick-slip behavior at the macroscale. However, unlike macroscale behavior, the minimum force after each slip is independent of velocity. The temporal period scales with velocity in a nearly power law fashion with an exponent between -1 and -2, similar to macroscale behavior. With increasing velocity, stick-slip behavior transitions into steady sliding. In the transition regime between stick-slip and smooth sliding, some slip events exhibit only partial force drops. The results are interpreted in the context of interfacial chemical bond formation and rate effects previously identified for nanoscale contacts. These results contribute to a physical picture of interfacial chemical bond-induced stick-slip, and further establish RSF laws at the nanoscale. PMID- 29190095 TI - Mechanism of a Class C Radical S-Adenosyl-l-methionine Thiazole Methyl Transferase. AB - The past decade has seen the discovery of four different classes of radical S adenosylmethionine (rSAM) methyltransferases that methylate unactivated carbon centers. Whereas the mechanism of class A is well understood, the molecular details of methylation by classes B-D are not. In this study, we present detailed mechanistic investigations of the class C rSAM methyltransferase TbtI involved in the biosynthesis of the potent thiopeptide antibiotic thiomuracin. TbtI C methylates a Cys-derived thiazole during posttranslational maturation. Product analysis demonstrates that two SAM molecules are required for methylation and that one SAM (SAM1) is converted to 5'-deoxyadenosine and the second SAM (SAM2) is converted to S-adenosyl-l-homocysteine (SAH). Isotope labeling studies show that a hydrogen is transferred from the methyl group of SAM2 to the 5' deoxyadenosine of SAM1 and the other two hydrogens of the methyl group of SAM2 appear in the methylated product. In addition, a hydrogen appears to be transferred from the beta-position of the thiazole to the methyl group in the product. We also show that the methyl protons in the product can exchange with solvent. A mechanism consistent with these observations is presented that differs from other characterized radical SAM methyltransferases. PMID- 29190098 TI - Spin-Orbit State-Selective C-I Dissociation Dynamics of the CH3I+ X Electronic State Induced by Intense Few-Cycle Laser Fields. AB - Studies of ultrafast molecular dynamics induced by intense laser fields can reveal new approaches to manipulating chemical reactions in the strong-field regime. Here, we show that intense few-cycle laser pulses can induce the spin orbit state-selective C-I dissociation of the iodomethane cation (CH3I+) in the X electronic state. Irradiation of CH3I by 6 fs laser pulses with peak intensities of 1.9 * 1014 W/cm2 followed by femtosecond extreme ultraviolet probing of the iodine 4d core-level transitions reveals dissociation of the CH3I+ X 2E1/2 state with a time constant of 0.76 +/- 0.16 ps. By contrast, the X 2E3/2 spin-orbit ground state does not exhibit any appreciable dissociation on the picosecond time scale. The observed spin-orbit state-selective dissociation of the X state is rationalized in terms of the laser-induced coupling to the A state. Our results suggest that the intense-laser control of photodissociation channels can be potentially extended to spin-orbit split states. PMID- 29190099 TI - Theoretical Study of the Light-Induced Spin Crossover Mechanism in [Fe(mtz)6]2+ and [Fe(phen)3]2. AB - The deactivation pathway of the light-induced spin crossover process in two Fe(II) complexes has been studied by combining density functional theory calculations for the geometries and the normal vibrational modes and highly correlated wave function methods for the energies and spin-orbit coupling effects. For the two systems considered, the mechanism of the photoinduced conversion from the low-spin singlet to the high-spin quintet state implies two intersystem crossings through intermediate triplet states. However, for the [Fe(mtz)6]2+ complex, the process occurs within few picoseconds and involves uniquely metal-centered electronic states, whereas for the [Fe(phen)3]2+ system the deactivation channel involves both metal to ligand charge transfer and metal centered states and takes place in a femtosecond time scale. PMID- 29190100 TI - Structure and Dynamics in Formamide-(H2O)3: A Water Pentamer Analogue. AB - Water self-association dominates the formation of microsolvated molecular clusters which may give rise to complex structures resembling those of pure water clusters. We present a rotational study of the complex formamide-(H2O)3 formed in a supersonic jet and several monosubstituted isotopologues. Formamide and water molecules form a four-body sequential cycle through N-H...O, O-H...O, and O H...O?C hydrogen bonds, resulting in a chiral structure with a nonplanar skeleton that can be overlapped to that of water pentamer. The analysis of the 14N-nucleus quadrupole coupling effects shows the depletion of the electron density of the N atom lone pair with respect to the bare formamide that affects the amide group C N and C?O distances. The study of the observed tunneling doublets shows that formamide-(H2O)3 follows a path to invert its structure driven by the flipping of water subunits and passing through successive nonplanar configurations, a motion reminiscent of the pseudorotation of water pentamer. PMID- 29190101 TI - Accuracy of Td-DFT in the Ultraviolet and Circular Dichroism Spectra of Deoxyguanosine and Uridine. AB - Accuracy of the time-dependent density functional theory (Td-DFT) was examined for the ultraviolet (UV) and circular dichroism (CD) spectra of deoxyguanosine (dG) and uridine, using 11 different DFT functionals and two different basis sets. The Td-DFT results of the UV and CD spectra were strongly dependent on the functionals used. The basis-set dependence was observed only for the CD spectral calculations. For the UV spectra, the B3LYP and PBE0 functionals gave relatively good results. For the CD spectra, the B3LYP and PBE0 with 6-311G(d,p) basis gave relatively permissible result only for dG. The results of other functionals were difficult to be used for the studies of the UV and CD spectra, though the symmetry adapted cluster-configuration interaction (SAC-CI) method reproduced well the experimental spectra of these molecules. To obtain valuable information from the theoretical calculations of the UV and CD spectra, the theoretical tool must be able to reproduce correctly both of the intensities and peak positions of the UV and CD spectra. Then, we can analyze the reasons of the changes of the intensity and/or the peak position to clarify the chemistry involved. It is difficult to recommend Td-DFT as such tools of science, at least from the examinations using dG and uridine. PMID- 29190103 TI - Tunneling Reaction Kinetics for the Hydrogen Abstraction Reaction H + H2S -> H2 + HS in the Interstellar Medium. AB - The hydrogen abstraction reaction between H and H2S, yielding HS and H2 as products, has been studied within the framework of interstellar surface chemistry. High-temperature rate constants below 2000 K are calculated in the gas phase and are in agreement with previously reported values. Subsequently, low temperature rate constants down to 55 K are presented for the first time that are of interest to astrochemistry, i.e., covering both bimolecular and unimolecular reaction mechanisms. For this, a so-called implicit surface model is used. In strict terms, this is a structural gas-phase model in which the restriction of the rotation in the solid state is taken into account. The calculated kinetic isotope effects are explained in terms of the difference in activation and delocalization. All rate constants are calculated at the UCCSD(T)-F12/cc-VTZ-F12 level of theory. Finally, we show that the energetics of the reaction is affected to an only small extent by the presence of H2O or H2S molecular clusters that simulate an ice surface, calculated at the MPWB1K/def2-TZVP level of theory. PMID- 29190102 TI - Integrative Proteomics-Metabolomics Strategy for Pathological Mechanism of Vascular Depression Mouse Model. AB - Vascular depression (VD), a subtype of depression, is caused by vascular diseases or cerebrovascular risk factors. Recently, the proportion of VD patients has increased significantly, which severely affects their quality of life. However, the current pathogenesis of VD has not yet been fully understood, and the basic research is not adequate. In this study, on the basis of the combination of LC-MS based proteomics and metabolomics, we aimed to establish a protein metabolism regulatory network in a murine VD model to elucidate a more comprehensive impact of VD on organisms. We detected 44 metabolites and 304 proteins with different levels in the hippocampus samples from VD mice using a combination of metabolomic and proteomics analyses with an isobaric tags for relative and absolute quantification (iTRAQ) method. We constructed a protein-to-metabolic regulatory network by correlating and integrating the differential metabolites and proteins using ingenuity pathway analysis. Then we quantitatively validated the levels of the bimolecules shown in the bioinformatics analysis using LC-MS/MS and Western blotting. Validation results suggested changes in the regulation of neuroplasticity, transport of neurotransmitters, neuronal cell proliferation and apoptosis, and disorders of amino acids, lipids and energy metabolism. These proteins and metabolites involved in these dis-regulated pathways will provide a more targeted and credible direction to study the mechanism of VD. Therefore, this paper presents an approach and strategy that was applied in integrative proteomics and metabolomics for research and screening potential targets and biomarkers of VD, which could be more precise and credible in a field lacking adequate basic research. PMID- 29190104 TI - Excited-State Symmetry Breaking in a Quadrupolar Molecule Visualized in Time and Space. AB - The influence of the length of the push-pull branches of quadrupolar molecules on their excited-state symmetry breaking was investigated using ultrafast time resolved IR spectroscopy. For this, the excited-state dynamics of an A-pi-D-pi-A molecule was compared with those of an ADA analogue, where the same electron donor (D) and acceptor (A) subunits are directly linked without a phenylethynyl pi-spacer. The spatial distribution of the excitation was visualized in real time by monitoring C=C and C=N vibrational modes localized in the spacer and acceptor units, respectively. In nonpolar solvents, the excited state is quadrupolar and the excitation is localized on the pi-D-pi center. In medium polarity solvents, the excitation spreads over the entire molecule but is no longer symmetric. Finally, in the most polar solvents, the excitation localizes on a single D-pi-A branch, contrary to the ADA analogue where symmetry breaking is only partial. PMID- 29190105 TI - Adaptive Finite Temperature String Method in Collective Variables. AB - Here we present a modified version of the on-the-fly string method for the localization of the minimum free energy path in a space of arbitrary collective variables. In the proposed approach the shape of the biasing potential is controlled by only two force constants, defining the width of the potential along the string and orthogonal to it. The force constants and the distribution of the string nodes are optimized during the simulation, improving the convergence. The optimized parameters can be used for umbrella sampling with a path CV along the converged string as the reaction coordinate. We test the new method with three fundamentally different processes: chloride attack to chloromethane in bulk water, alanine dipeptide isomerization, and the enzymatic conversion of isochorismate to piruvate. In each case the same set of parameters resulted in a rapidly converging simulation and a precise estimation of the potential of mean force. Therefore, the default settings can be used for a wide range of processes, making the method essentially parameter free and more user-friendly. PMID- 29190106 TI - Effect of Aspect Ratio on Multiparticle Auger Recombination in Single-Walled Carbon Nanotubes: Time Domain Atomistic Simulation. AB - Many-particle Auger-type processes are common in nanoscale materials due to a combination of high densities of states that can support multiple excitations and substantial Coulomb coupling between charges enhanced by quantum confinement. Auger decay dynamics in (10,5) semiconductor carbon nanotubes (CNT) with different aspect ratios and particle densities are simulated in time domain using global flux surface hopping, recently developed and implemented within Kohn-Sham tight-binding density functional theory. Despite an increasing density of states, the multiparticle Auger recombination rate decreases in longer CNTs. The atomistic simulation shows that the effect is directly related to the coupling between electronic states, which decreases as the aspect ratio becomes larger. The dependence on tube length is stronger for three-exciton than two-exciton recombination and the calculated time scale ratio approaches the experimental value measured for long CNTs. Phonon-assisted transitions play a particularly important role during Auger recombination. Electron-phonon relaxation is faster than the recombination, and Auger transitions are assisted by phonons over a range of frequencies up to the G-mode. The involvement of phonons strongly enhances the probability of transitions involving asymmetric electron-hole pairs. The time-domain atomistic simulation mimics directly time-resolved optical experiments and provides a detailed, systematic analysis of the phonon-assisted Auger dynamics. PMID- 29190107 TI - Minimum Line Width of Surface Plasmon Resonance in Doped ZnO Nanocrystals. AB - The optical response of ZnO nanocrystals (NCs) doped with Al (Ga) impurities is calculated using a model that incorporates the effects of quantum confinement, dielectric mismatch, surface, and ionized impurity scattering. For dopant concentrations of a few percent, the NC polarizability is dominated by a localized surface plasmon resonance (LSPR) in the infrared (IR) which follows the Drude-Lorentz law for NC diameter above ~10 nm but is strongly blue-shifted for smaller diameters due to quantum confinement effects. The intrinsic width of the LSPR peak is calculated in order to characterize plasmon losses induced by ionized impurity scattering. Widths below 80 meV are found in the best cases, in agreement with the lowest values recently measured on single NCs. These results confirm that doped ZnO NCs are very promising for the development of IR plasmonics. The width of the LSPR peak strongly increases when dopants are placed near the surface of the NCs or when additional fixed charges are present.

AB - In the last decade, the production and consumption of organic food have increased steadily worldwide, despite the lower productivity of organic crops. Indeed, the population attributes healthier properties to organic food. Although scientific evidence is still scarce, organic agriculture seems to contribute to maintaining an optimal health status and decreases the risk of developing chronic diseases. This may be due to the higher content of bioactive compounds and lower content of unhealthy substances such as cadmium and synthetic fertilizers and pesticides in organic foods of plant origin compared to conventional agricultural products. Thus, large long-term intervention studies are needed to determine whether an organic diet is healthier than a diet including conventionally grown food products. This review provides an update of the present knowledge of the impact of an organic versus a conventional food diet on health. PMID- 29190114 TI - The scientific basis for healthful carbohydrate profile. AB - Dietary guidelines indicate that complex carbohydrates should provide around half of the calories in a balanced diet, while sugars (i.e., simple carbohydrates) should be limited to no more than 5-10% of total energy intake. To achieve this public health goal a collective effort from different entities including governments, food & beverage industries and consumers is required. Some food companies have committed to continually reduce sugars in their products. Different solutions can be used to replace sugars in food products but it is important to ensure that these solutions are more healthful than the sugars they replace. The objectives of this paper are, (1) to identify carbohydrates and carbohydrates sources to promote and those to limit for dietary intake and food product development, based on current knowledge about the impact of carbohydrates on the development of dental caries, obesity and cardio-metabolic disorders (2) to evaluate the impact of food processing on the quality of carbohydrates and (3) to highlight the challenges of developing healthier products due to the limitations and gaps in food regulations, science & technology and consumer education. PMID- 29190115 TI - Quality of plant-based food materials and its prediction during intermittent drying. AB - In most drying processes, several physical, chemical and nutritional modifications take place in food products. Innovative drying techniques such as intermittent drying can enhance the quality of dehydrated products effectively and efficiently. Intermittent drying is a technique where drying conditions are changed through varying the drying air temperature, humidity, velocity, pressure, or even mode of heat input. This drying technique has been successfully applied to overcome the problems of conventional drying systems such as longer time consumption, case hardening, lower energy efficiency and poor-quality attributes. However, as the effect of intermittent drying on food quality is not yet well understood, a comprehensive study of quality change during intermittent drying is crucial. The main aim of this paper is to present a thorough review of the potential effect of intermittent drying methods on physical, chemical, nutritional, and stability characteristics of plant-based food material. It is found that application of intermittency using different drying systems has a significant effect on product quality and its stability. In addition, a comprehensive review on existing models of physio/biochemical kinetics for food drying is presented. Finally, the paper is concluded with the discussion of the current challenges and future directions of intermittent drying for producing high-quality dried food products.

AB - BACKGROUND: The pathophysiological mechanisms behind proliferation of fibroblasts and deposition of dense collagen matrix in idiopathic frozen shoulder remain unclear. Alarmins (also known as danger signals) are endogenous molecules that are released into the extracellular milieu after infection or tissue injury and that signal cell and tissue damage. PURPOSE: To investigate whether the presence of alarmins is higher in patients with idiopathic frozen shoulder than in control subjects. STUDY DESIGN: Controlled laboratory study. METHODS: Shoulder capsule samples were collected from 10 patients with idiopathic frozen shoulder and 10 patients with unstable shoulders (control). The samples were stained with hematoxylin and eosin (H&E) and analyzed by immunohistochemistry using antibodies against alarmin molecules including high-mobility group protein B1 (HMGB1), interleukin 33, S100A8, S100A9, and the peripheral nerve marker PGP9.5. Immunoreactivities were rated in a blinded fashion from "none" to "strong." Immunohistochemical distribution within the capsule was noted. Before surgery, patient-ranked pain frequency, severity, stiffness, and the range of passive shoulder motion were recorded and statistically analyzed. RESULTS: Compared with control patients, patients with frozen shoulder had greater frequency and severity of self-reported pain ( P = .02) and more restricted range of motion in all planes ( P < .05). H&E-stained capsular tissue from frozen shoulder showed fibroblastic hypercellularity and increased subsynovial vascularity. Immunoreactivity of alarmins was significantly stronger in frozen shoulder capsules compared with control capsules ( P < .05). Furthermore, the expression of the alarmin molecule HMGB1 significantly correlated ( r > 0.9, P < .05) with the severity of patient-reported pain. CONCLUSION: This study demonstrates a potential role for key molecular danger signals in frozen shoulder and suggests an association between the expression of danger molecules and the pain experienced by patients.

AB - Gut microbiomes may have a significant impact on mood and cognition, which is leading experts towards a new frontier in neuroscience. Studies have shown that increase in the amount of good bacteria in the gut can curb inflammation and cortisol level, reduces symptoms of depression and anxiety, lowers stress reactivity, improves memory and even lessens neuroticism and social anxiety. This shows that, probably the beneficial gut bacteria or probiotics function mechanistically as delivery vehicles for neuroactive compounds. Thus, a psychobiotic is a live organism, when ingested in adequate amounts, produces a health benefit in patients suffering from psychiatric illness. Study of these novel class of probiotics may open up the possibility of rearrangement of intestinal microbiota for effective management of various psychiatric disorders.

PMID- 29190119 TI - When the Plus Sign is a Negative: Challenging and Reinforcing Embodied Stigmas Through Outliers and Counter-Narratives. AB - When individuals become aware of their stigma, they attempt to manage their identity through discourses that both challenge and reinforce power. Identity management is fraught with tensions between the desire to fit normative social constructions and counter the same discourse. This essay explores identity management in the midst of the embodied stigmas concerning unplanned pregnancy during college and raising a biracial son. In doing so, this essay points to the difference between outlier narratives and counter-narratives. The author encourages health communication scholars to explore conditions under which storytelling moves beyond the personal to the political. Emancipatory intent does not guarantee emancipatory outcomes. Storytelling can function therapeutically for individuals while failing to redress forces that constrain human potential and agency. PMID- 29190121 TI - Chromosomal Thermal Index: a comprehensive way to integrate the thermal adaptation of Drosophila subobscura whole karyotype. AB - Drosophila has demonstrated to be an excellent model to study the adaptation of organisms to global warming, with inversion chromosomal polymorphism having a key role in this adaptation. Here, we introduce a new index (Chromosomal Thermal Index or CTI) to quantify the thermal adaptation of a population according to its composition of "warm" and "cold" adapted inversions. This index is intuitive, has good statistical properties, and can be used to hypothesis on the effect of global warming on natural populations. We show the usefulness of CTI using data from European populations of D. subobscura, sampled in different years. Out of 15 comparisons over time, nine showed significant increase of CTI, in accordance with global warming expectations. Although large regions of the genome outside inversions contain thermal adaptation genes, our results show that the total amount of warm or cold inversions in populations seems to be directly involved in thermal adaptation, whereas the interactions between the inversions content of homologous and non-homologous chromosomes are not relevant.

AB - This study aimed to provide normative references for Mexican Americans on neuropsychological measures of cognitive functioning. Data were analyzed from a total of 797 Mexican-Americans recruited across three Texas-based studies with approximately one-half of the participants tested in Spanish. Normative tables include: MMSE, AMNART, WMS-III (Logical Memory I, II; Visual Reproduction I, II; Digit Span), CERAD, RAVLT, Exit25, CLOX 1 & 2, Trail Making Test- A&B, BNT, COWA, and Animal Naming. The norms were stratified by education then age. Normative references were generated for Texas-based Mexican Americans and data may be limited to the population sampled.

AB - INTRODUCTION: This project used Boot Camp Translation (BCT) to translate the complex medical jargon of biobanking into locally relevant evidence-based messages and materials to support increased knowledge and understanding in the local community. METHODS: Biobank BCT was a partnership of 16 community members and 5 academic researchers. The partnership met for 8 months. RESULTS: The partnership developed five main and seven submessages to assist patients and community members in making an informed decision about enrollment in a biobank. DISCUSSION: The resulting messages balance an individual's right to privacy and choice, while encouraging participation for the greater good.

AB - In quantitative PCR (qPCR), replicates can minimize the impact of intra-assay variation; however, inter-assay variations must be minimized to obtain a robust quantification method. The method proposed in this study uses Savitzky-Golay smoothing and differentiation (SGSD) to identify a derivative-maximum-based cycle of quantification. It does not rely on curve modeling, as is the case with many existing techniques. PCR fluorescence data sets challenged for inter-assay variations (different thermocycler units, different reagents batches, different operators, different standard curves, and different labs) were used for the evaluation. The algorithm was compared with a four-parameter logistic model (4PLM) method, the Cy0 method, and the threshold method. The SGSD method compared favourably with all methods in terms of inter-assay variation. SGSD was statistically different from the 4PLM (P = 0.03), Cy0 (P = 0.05), and threshold (P = 0.004) methods on relative error comparison basis. For intra-assay variations, SGSD outperformed the threshold method (P = 0.005) and equalled the 4PLM and Cy0 methods (P > 0.05) on relative error basis. Our results demonstrate that the SGSD method could potentially be an alternative to sigmoid modeling based methods (4PLM and Cy0) when PCR data are challenged for inter-assay variations. PMID- 29190124 TI - The Role of Media in Non-Directed (Altruistic) Living Kidney Donation. AB - This study seeks to characterize how non-directed living kidney donors use media and informational resources over the course of their kidney donation journey. We conducted semi-structured interviews with non-directed donors (NDDs) who initiated kidney transplant chains. Interview transcripts were reviewed and references to media or informational resources were classified by type and pattern of use. More than half (57%) of NDDs reported that an identifiable media or informational resource resulted in their initial interest in donation. Two thirds (67%) of NDDs cited the influence of stories and personal narratives on their decision to donate. After transplant, media and informational resources were used to promote organ donation, connect with other donors or recipients, and reflect on donation. From the study's findings, we conclude that media and informational resources play an important role in the process of donation for NDDs, including inspiring interest in donation through personal narratives. Media sources provide emotionally and intellectually compelling discussions that motivate potential donors. The results of this study may facilitate the development of more targeted outreach to potential donors through use of personal narratives in articles and television programming about donation. PMID- 29190125 TI - Mitotic instability in triploid and tetraploid one-year-old eastern oyster, Crassostrea virginica, assessed by cytogenetic and flow cytometry techniques. AB - For commercial oyster aquaculture, triploidy has significant advantages. To produce triploids, the principal technology uses diploid * tetraploid crosses. The development of tetraploid brood stock for this purpose has been successful, but as more is understood about tetraploids, it seems clear that chromosome instability is a principal feature in oysters. This paper is a continuation of work to investigate chromosome instability in polyploid Crassostrea virginica. We established families between tetraploids-apparently stable (non-mosaic) and unstable (mosaic)-and normal reference diploids, creating triploid groups, as well as tetraploids between mosaic and non-mosaic tetraploids. Chromosome loss was about the same for triploid juveniles produced from either mosaic or non mosaic tetraploids or from either male or female tetraploids. However, there was a statistically significant difference in chromosome loss in tetraploid juveniles produced from mosaic versus non-mosaic parents, with mosaics producing more unstable progeny. These results confirm that chromosome instability, as manifested in mosaic tetraploids, is of little concern for producing triploids, but it is clearly problematic for tetraploid breeding. Concordance between the results from cytogenetics and flow cytometry was also tested for the first time in oysters, by assessing the ploidy of individuals using both techniques. Results between the two were non-concordant. PMID- 29190126 TI - Understanding the Effects of Stigma Messages: Danger Appraisal and Message Judgments. AB - Media coverage of health issues has been criticized for creating health stigmas. The model of stigma communication (MSC, Smith, 2007) provides insights into why this is so, but it has two problems: Some of its mediators have not been supported, and it does not do a good job of predicting the transmission of stigma messages (i.e., social transmission). We present a revised model of stigma message effects in which exposure to stigma messages leads to stigma beliefs and stigmatization as a result of a person-oriented danger appraisal. In addition, message judgments-shock value and common ground-are introduced as mediators of the relationship between danger appraisal and social transmission. Participants (N = 200) were randomly assigned to read a health story written either with or without the intrinsic features of stigma messages. The revised model of stigma message effects was supported: Reading a health news story written with (vs. without) the intrinsic features of stigma messages resulted in greater danger appraisal, which directly predicted stigma-related outcomes and indirectly predicted social transmission through message judgments. Social transmission varied by message judgment: Shocking messages were shared in ways that facilitate diffusion, but common ground messages were shared with influential others, suggesting different means by which stigma as a collective norm may emerge from interactions among community members. PMID- 29190127 TI - Detection of Salmonella Infection in Chickens by an Indirect Enzyme-Linked Immunosorbent Assay Based on Presence of PagC Antibodies in Sera. AB - The outcomes of infection of humans and animals with Salmonella range from a persistent asymptomatic carrier state to temporal mild gastroenteritis or severe systemic infection. A rapid and accurate diagnostic test would help formulate strategies for effective prevention of their infections in the animal population. Current sequencing data predict that the outer membrane protein, PagC, is present in all common Salmonella serovars with sequence similarities of more than 98%. PagC sequences in other bacterial species are less than 65% similarity at the amino acid level to those of Salmonella PagC. We hypothesized that PagC could be immunogenic and detection of antibodies to this protein could be an accurate indicator of Salmonella infection. The pagC gene from Salmonella enterica serovar Typhimurium CVCC542 was expressed in Escherichia coli. The purified recombinant PagC protein was immobilized in microtiter plate wells. Sera from SPF chickens infected with Salmonella or other non-Salmonella pathogens by injection were added and binding of PagC protein was detected by the horseradish peroxidase (HRP)-labeled goat anti-chicken antibody. Sera from Salmonella-infected chickens showed high specificity in contrast to the sera from chickens infected with other bacteria. When 87 Salmonella antibody-positive sera from Salmonella Pullorum orally infected SPF chicken and 93 negative sera from uninfected SPF chicken were tested, 98.3% agreement was detected. The rPagC enzyme-linked immunosorbent assay (ELISA) and agglutination had 80.6% agreement in detecting 252 clinical chicken sera samples. These results suggest that PagC antibody-based indirect ELISA can serve as a convenient and novel method for the diagnosis of Salmonella infection. PMID- 29190128 TI - Suicide Prevention Media Campaigns: A Systematic Literature Review. AB - Suicide prevention media campaigns are gaining traction as a means of combatting suicide. The current review set out to synthesize information about the effectiveness of these campaigns. We searched four electronic databases for studies that provided evidence on the effectiveness of media campaigns. We focused on studies that described an evaluation of the effectiveness of an entire campaign or a public service announcement explicitly aimed at suicide prevention. We identified 20 studies of varying quality. Studies that looked at whether campaign exposure leads to improved knowledge and awareness of suicide found support for this. Most studies that considered whether campaign materials can achieve improvements in attitudes toward suicide also found this to be the case, although there were some exceptions. Some studies found that media campaigns could boost help-seeking, whereas others suggested that they made no difference or only had an impact when particular sources of help or particular types of help seeking were considered. Relatively few studies had sufficient statistical power to examine whether media campaigns had an impact on the ultimate behavioral outcome of suicides, but those that did demonstrated significant reductions. Our review indicates that media campaigns should be considered in the suite of interventions that might be used to prevent suicide. Evidence for their effectiveness is still amassing, but there are strong suggestions that they can achieve positive results in terms of certain suicide-related outcomes. Care should be taken to ensure that campaign developers get the messaging of campaigns right, and further work is needed to determine which messages work and which ones do not, and how effective messages should be disseminated. There is an onus on those developing and delivering campaigns to evaluate them carefully and to share the findings with others. There is a need for evaluations that employ rigorous designs assessing the most pertinent outcomes. These evaluations should explore the nature of given campaigns in detail - in particular the messaging contained within them - in order to tease out which messages work well and which do not. They should also take into account the reach of the campaign, in order to determine whether it would be reasonable to expect that they might have their desired effect. PMID- 29190129 TI - Polymorphism rs10483727 in the SIX1/SIX6 Gene Locus Is a Risk Factor for Primary Open Angle Glaucoma in a Saudi Cohort. AB - AIMS: Variant rs10483727 in the SIX1/SIX6 locus has been significantly associated with primary open angle glaucoma (POAG) in multiple ethnic groups. We conducted a case-control study to investigate the association between this variant and POAG in a Saudi cohort. MATERIALS AND METHODS: Polymorphism rs10483727 was genotyped by using a TaqMan(r) assay in 186 subjects comprising 92 unrelated POAG cases and 94 controls all of Saudi origin. RESULTS: The "C" allele frequency was 0.33 and 0.45 among POAG cases and controls, respectively (odds ratio [OR] = 0.58, 95% confidence interval [CI] = 0.38-0.89; p = 0.013), suggesting a protective effect; and the "T" allele was associated with increased susceptibility to POAG (OR = 1.7, 95% CI = 1.11-2.58; p = 0.013). Genotype distribution was also significantly associated with POAG (chi2 = 6.41, df = 2, p = 0.041). Endophenotype traits such as intraocular pressure and cup/disk ratio did not show any significant genotype distribution in POAG cases. A binary logistic regression analysis used to evaluate the effects of age, gender, and genotype on the likelihood of having POAG showed that genotype distribution (p = 0.012) significantly affected the disease outcome as compared with age (p = 0.055) and sex (p = 0.432). CONCLUSION: The "T" allele of the rs10483727 polymorphism is an independent significant risk factor for POAG in the Saudi population. PMID- 29190130 TI - Genomic relationships among sixteen species of Avena based on (ACT)6 trinucleotide repeat FISH. AB - Knowledge of the locations of repeat elements could be very important in the assembly of genome sequences and their assignment to physical chromosomes. Genomic and species relationships among 16 species were investigated using fluorescence in situ hybridization (FISH) with the Am1 and (ACT)6 probes. The Am1 oligonucleotide probe was particularly enriched in the C genomes, whereas the (ACT)6 trinucleotide repeat probe showed a diverse distribution of hybridization patterns in the A, AB, C, AC, and ACD genomes but might not be present in the B and D genomes. The hybridization pattern of Avena sativa was very similar to that of A. insularis, indicating that this species most likely originated from A. insularis as a tetraploid ancestor. Although the two FISH probes failed to identify relationships of more species, this proof-of-concept approach opens the way to the use of FISH probes in assigning other signature elements from genomic sequence to physical chromosomes. PMID- 29190132 TI - CORRECTION. PMID- 29190131 TI - A comparison of overtime patrol stops made inside and out of cluster identified hotspots. AB - OBJECTIVE: The annual rate of impaired driving crashes in the United States has remained nearly constant over the last decade. While engineers, educators, enforcement, and emergency response personnel have worked diligently in their combined efforts to reduce the loss of life, there is still significant progress to be made. One area of recent interest is the use of data driven enforcement. The basis for data driven enforcement is the use of statistical clustering to identify geographic areas that represent the location of problem identification for various criminal or traffic offenses. In the case of impaired driving fatalities, the clustering represents locations with high rates of impaired driving crashes. Law enforcement officers and supervisors may allocate resources towards more specifically and efficiently addressing problem areas. METHODS: While data driven enforcement has been proven to be an effective tool in addressing crime and traffic safety problems, it has been a slow process for agencies to adopt data driven techniques. This study aims to explore the difference in traffic stops made inside and outside of hotspot identified areas. The study uses data from the Stark County Operating a Vehicle Impaired Task Force between 2013 and 2014. RESULTS: The analysis determined that stop occurring in hotspot defined areas are more likely to result in impaired driving arrests and seatbelt citations. Additionally it is found that the average cost of impaired driving arrests is significantly cheaper for stops occurring inside of hotspot areas. CONCLUSION: Clustering as a means of directing law enforcement efforts are a way to increase the productivity and benefits of law enforcement agencies with limited finances or personnel. From this study it is seen that traffic stops made within defined cluster or hot spot areas are more effective in resulting in OVI arrests.

PMID- 29190137 TI - HIGH-RISK GASTRIC PATHOLOGY AND PREVALENT AUTOIMMUNE DISEASES IN PATIENTS WITH PERNICIOUS ANEMIA. AB - OBJECTIVE: Pernicious anemia (PA) develops from atrophic gastritis due to autoimmune destruction of parietal cells and results in achlorhydria, vitamin B12 and iron deficiencies, anemia, neurologic deficits, and premalignant and malignant stomach lesions. We report the presentation, diagnosis and gastric complications of PA in patients from an endocrinology practice. METHODS: Thirty four patients (31 female, 3 male) with PA who underwent esophagogastroduodenoscopy (EGD) or gastrectomy were identified. Pertinent clinical, laboratory, and pathology findings were reviewed and summarized. RESULTS: The mean age of patients was 58.6 +/- 14.2 years; the onset of PA was age 50.2 +/- 15.3 years. Anemia reflected vitamin B12 and/or iron deficiencies. Parietal cell antibodies (PCA) were detected in 97% of patients, and intrinsic factor blocking antibody (IFBA) was found in 52%. Fasting gastrin and chromogranin A levels were elevated (1,518.0 +/- 1,588.3 pg/mL, and 504.9.1 +/- 1,524.9 ng/mL respectively). Autoimmune or immunologic diseases (AIDs) were present in 32/34 patients. Stomach pathology showed premalignant or malignant lesions in 26 patients, including gastric neuroendocrine tumors (GNETs) in 6 and adenocarcinoma in 1. One patient presented with neurologic symptoms and subacute combined degeneration of the posterior column of the spinal cord. CONCLUSION: PA should be suspected in patients with unexplained anemia or neurologic symptoms. The diagnosis of PA relies on fasting gastrin and gastric auto-antibody testing, in addition to hematologic evaluation. EGD with measurement of gastric pH and biopsies of the fundus and antrum identifies patients with achlorhydria, atrophic gastritis, and premalignant and malignant stomach lesions. EGD surveillance of patients with high-risk stomach lesions is recommended.

PMID- 29190138 TI - LETTER TO THE EDITOR. PMID- 29190139 TI - The 50/50 Block Schedule: Impact on Residents' and Preceptors' Perceptions, Patient Outcomes, and Continuity of Care. AB - PROBLEM: Traditionally, internal medicine continuity clinic consists of a half day per week, regardless of rotation, which may create conflict with ongoing inpatient responsibilities. A 50/50 block schedule, which alternates inpatient and outpatient rotations and concentrates continuity clinic during outpatient rotations, minimizes conflicting responsibilities. However, its impact on patient care has not been widely studied. Continuity is a concern, and intervisit continuity in particular has not been evaluated. INTERVENTION: We implemented a 50/50 block model with "clinic buddy" system to optimize continuity and assessed outcomes pre- and postintervention. Residents alternated inpatient and elective blocks, with clinic 1 full day per week on elective blocks only. Resident and preceptor perceptions were measured using 5-point Likert surveys to evaluate impact on clinic experience and workload. The authors calculated visit and intervisit continuity using a Usual Provider of Care index and measured blood pressure and hemoglobin A1c as quality markers to evaluate the impact on continuity and quality of care. CONTEXT: Participants were 208 medicine residents and 39 core faculty members at 3 University of Pittsburgh Medical Center clinics. The intervention was implemented in June 2014. OUTCOME: In the 50/50 system, inpatient distractions decreased (3.59 vs. 1.71, p < .001). Residents more strongly agreed that there was adequate time for conferences (3.33 vs. 4.05), they worked well within the system to achieve best patient care (3.13 vs. 3.61), and multidisciplinary teams worked well together (3.51 vs. 4.08) (all p < .001). Intervisit continuity was unchanged (73%, both models, p = .79). Visit continuity decreased (67.2% vs. 63.7%, p < .001). Blood pressure and hemoglobin A1c were unchanged. LESSONS LEARNED: This 50/50 model minimized inpatient distractions in clinic and increased perceived time for learning. Residents reported improved sense of patient ownership, relations within the multidisciplinary team, and integration into the clinic system. Intervisit continuity was preserved, visit continuity was slightly decreased, and patient outcomes were not impacted in this model. PMID- 29190140 TI - Validity Evidence for a Residency Admissions Standardized Assessment Letter for Pediatrics. AB - : Construct: This study aims to provide validity evidence for the standardized Assessment Letter for Pediatrics as a measure of competencies expected of a 1st year pediatrics resident as part of a pediatric residency admissions process. BACKGROUND: The Narrative Letter of Recommendation is a frequently used tool in the residency admissions process even though it has poor interrater reliability, lacks pertinent content, and does not correlate with residency performance. A newer tool, the Standardized Letter, has shown validity evidence for content and interrater reliability in other specialties. We sought to develop and provide validity evidence for the standardized Assessment Letter for Pediatrics. APPROACH: All 2012 and 2013 applicants invited to interview at the University of Geneva Pediatrics Residency Program provided 2 standardized Assessment Letters. Content for the letter was based on CanMEDS roles and ratings of 6 desired competencies and an overall assessment. Validity evidence was gathered for internal structure (Cronbach's alpha and generalizability), response process (interrater reliability with intraclass correlation), relations to other variables (Pearson's correlation coefficient), and consequences (logistic regression to predict admission). RESULTS: One hundred fourteen faculty completed 142 standardized Assessment Letters for 71 applicants. Average overall assessment was 3.0 of 4 (SD = 0.59). Cronbach's alpha was 0.93. The G-coefficient was 0.59. The decision study projected that four Assessment Letters are needed to attain a G-coefficient of 0.73. Applicant variance (28.5%) indicated high applicant differentiation. The Assessment Letter intraclass coefficient was 0.51, 95% confidence interval (CI) [0.43, 0.59]. Assessment Letter scores were correlated with the structured interview (r = .28), 95% CI [0.05, 0.51]; global rating (r = .36), 95% CI [0.13, 0.58]; and admissions decision (r = .25), 95% CI [0.02, 0.46]. Assessment Letter scores did not predict the admissions decision (odds ratio = 1.67, p = .37) after controlling for the unique contribution of the structured interview and global rating scores. CONCLUSION: Validity evidence supports use of the Assessment Letter for Pediatrics; future studies should refine items to improve predictive validity and explore how to best integrate the Assessment Letter into the residency admissions process. PMID- 29190141 TI - Childhood Maltreatment, Bullying Victimization, and Psychological Distress Among Gay and Bisexual Men. AB - Sexual minority men report higher psychological distress than heterosexual men, including depression and anxiety. Research suggests that these health disparities may be due to the heightened stressors that gay, lesbian, and bisexual individuals experience. Some of these stressors occur early on in life, such as childhood abuse and bullying, and may include stressors that are topically related to sexual minority status, such as anti-gay bullying and teasing for gender nonconformity to masculine gender norms. We tested a structural equation model on the association between negative childhood experiences and adult psychological distress among 304 gay and bisexual men. The model fit the data well, and demonstrated an indirect effect of negative childhood experiences on adult psychological distress via dysfunctional thoughts toward oneself. The results integrate the childhood abuse and anti-gay bullying victimization literatures by showing that both forms of adverse childhood experiences are associated with adult psychological distress. The findings suggest the benefit of treatments to reduce negative, dysfunctional thoughts among gay and bisexual men who have experienced adverse childhood events. PMID- 29190142 TI - Biomedical Science Undergraduate Major: A New Pathway to Advance Research and the Health Professions. AB - PROBLEM: Many students entering professional degree programs, particularly M.D., Ph.D., and M.D./Ph.D., are not well prepared regarding the breadth of scientific knowledge required, communication skills, research experience, reading and understanding the scientific literature, and significant shadowing (for M.D. related professions). In addition, physician scientists are a needed and necessary part of the academic research environment but are dwindling in numbers. INTERVENTION: In response to predictions of critical shortages of clinician investigators and the lack of proper preparation as undergraduates for these professions, the Biomedical Science (BMS) undergraduate major was created at The Ohio State University to attract incoming college freshmen with interests in scientific research and the healthcare professions. The intent of this major was to graduate an elite cohort of highly talented individuals who would pursue careers in the healthcare professions, biomedical research, or both. CONTEXT: Students were admitted to the BMS major through an application and interview process. Admitted cohorts were small, comprising 22 to 26 students, and received a high degree of individualized professional academic advising and mentoring. The curriculum included a minimum of 4 semesters (or 2 years) of supervised research experience designed to enable students to gain skills in clinical and basic science investigation. In addition to covering the prerequisites for medicine and advanced degrees in health professions, the integrated BMS coursework emphasized research literacy as well as skills related to work as a healthcare professional, with additional emphasis on independent learning, teamwork to solve complex problems, and both oral and written communication skills. Supported by Ohio State's Department of Internal Medicine, a unique clinical internship provided selected students with insights into potential careers as physician scientists. OUTCOME: In this educational case report, we describe the BMS undergraduate major and its outcomes after 10 years of implementation. Major outcomes include the strength of the major's matriculates (average ACT score = 32.6; average high school class percentile rank = 95.5) and the high percentage of BMS students who pursued graduate/professional degrees (91%; n = 110). Other markers of success include the strong focus on research, which resulted in 120 articles published by graduates to date (range = 0-12/student; 43% with at least 1 peer-reviewed journal article). LESSONS LEARNED: Based on its successes, adoption of a similar program at other academic medical centers would help feed the pipeline of well trained health professionals and biomedical researchers. PMID- 29190143 TI - Perceptions of Tobacco Control Media Campaigns Among Smokers With Lower Socioeconomic Status. AB - People with low socioeconomic status (SES) in the United States have disparately high rates of smoking and experience disproportionately high burdens of smoking related disease. Tobacco control media campaigns are a critical strategy for reducing tobacco use prevalence, but evidence is mixed about the optimal use of mass media to reach and promote tobacco use cessation among people with low SES. Improved understanding of the factors influencing how low-SES tobacco users evaluate tobacco control media campaigns may inform development of more effective messages and strategies. Focus groups with primarily low-SES smokers in Connecticut were conducted, finding that participants had seen many tobacco control television ads that used graphic imagery and testimonials, but participants voiced two main themes that limited ad effectiveness: (1) skepticism about the content of ads, the role of the tobacco industry and the government in sponsoring the ads, and the safety and efficacy of cessation supports; and (2) barriers to quitting such as stress, social contexts, and addiction that participants perceived as being underappreciated in the context of the ads. Tobacco control media campaigns targeting low-SES tobacco users may need additional messages, tools, or refinements to more optimally motivate this group to make quit attempts. PMID- 29190144 TI - Heterogeneity in Gender/Sex Sexualities: An Exploration of Gendered Physical and Psychological Traits in Attractions to Women and Men. AB - Sexuality research has generally privileged attractions based on partners' sexed physical bodies over attractions based on other features, including gender expression and personality traits. Gender may actually be quite central to sexual attractions. However, its role has received little empirical attention. To explore how gendered and sexed features, among others, are related to sexual attractions, the current study assessed how sexually diverse individuals described their attractions to feminine, masculine, and gender-nonspecific features of women and men. A sample of 280 individuals responded to the open ended questions: "What do you find attractive in a man?" and "What do you find attractive in a woman?" We coded responses as pertaining to physical and/or psychological features, and as being gendered masculine, feminine, or gender nonspecific. Our analyses showed that participants named gender-nonspecific features most frequently in responses to both questions, feminine features more than masculine features in attractions to women, and masculine features more than feminine features in attractions to men. Additionally, participants named feminine physical features more than masculine physical features, and masculine psychological features more than feminine psychological features, both in their attractions to women and overall. These results highlight the importance of considering attractions based on gender, rather than sex alone.

PMID- 29190146 TI - Prevalence of depression after TBI in a prospective cohort: The SHEFBIT study. AB - OBJECTIVE: The objective is to measure the prevalence of depression after traumatic brain injury (TBI) and the features associated with increased risk in a cohort that reflects clinical practice. METHODS: Prospective TBI admissions to a large Teaching Hospital Emergency Department were recruited over a 2-year period. Assessments for depression and other psychosocial and global outcomes were completed at 3 months post-injury. Comparisons were made with demographic and injury features of interest to establish any associations of depression risk. RESULTS: Out of 827 individuals, 774 (94%) successfully attended follow-up. A percentage of 56.3 had depression using a HADS-D >8. Depressed individuals had higher levels of post-concussion symptoms and worse psychosocial and global outcome ratings. In multivariable analysis, features associated with depression were TBI severity, previous psychiatric history, alcohol intoxication at time of injury, female gender and nonwhite ethnicity. Those with a normal CT scan showed higher risk than those with only mild abnormality and were comparable to those with much more marked CT changes. CONCLUSION: The 3-month prevalence of depression after TBI is very high and associated with several injury and demographic features. Future long-term follow-up of this cohort aims to confirm the features that increase risk; this may allow the earlier targeting of susceptible individuals for depression interventions. PMID- 29190147 TI - When normal scores don't equate to independence: Recalibrating ratings of neurobehavioural disability from the 'St Andrew's - Swansea Neurobehavioural Outcome Scale' to reflect context-dependent support. AB - PRIMARY OBJECTIVE: Context is critical to the interpretation of measurement instruments that capture acquired brain injury (ABI) outcomes. Ratings reflect behaviours and abilities observed in a particular setting; it cannot be assumed that results are generalizable beyond these. This study explored the utility of a method to convey the impact of context-dependent support given on ratings of neurobehavioural disability (NBD) using the St Andrews-Swansea Neurobehavioural Outcome Scale (SASNOS). METHODS AND PROCEDURES: A supplementary SASNOS scoring system was developed using a mixed-methods approach. Dependency ratings were used to recalibrate standardised SASNOS scores to reflect support received. To aid interpretation, an expert panel reviewed SASNOS ratings for 50 ABI cases participating in residential neurobehavioural rehabilitation programmes. An end user survey was undertaken to explore some of its psychometric properties. Finally, a representative case study was employed to illustrate its clinical utility. MAIN OUTCOMES: The expert panel identified three dependency profiles: (1) Normal/Independent; (2) Normal/Dependent; and (3) Abnormal/Review. Survey results supported face and construct validity of the supplementary system; the case study demonstrated benefits of discriminating between dependency profiles. CONCLUSIONS: The supplementary scoring system enables SASNOS to convey the impact of support received on ratings of NBD, solidifying its usefulness for measuring outcomes in rehabilitation.

AB - Sexual health research with transfeminine persons (individuals assigned male at birth who identify as female or feminine) has focused on HIV infection and sexual function following medical treatments. Yet, approximately half of transfeminine persons in Ontario, Canada, reported no partnered sex in the previous year. Therefore, we identified sociodemographic, social, and psychosocial factors associated with past-year sexual inactivity among transfeminine Ontarians. A multi-mode respondent-driven sampling survey of transgender people was conducted in 2009-2010 (N = 433), including 173 transfeminine individuals who had ever been sexually active. Frequencies and regression models were weighted using RDS II methods; prevalence ratios were estimated from logistic regression models using average marginal predictions. Of sexually experienced transfeminine persons, 43% (95% CI [31, 55]) reported no past-year sex partners. Sexual inactivity was independently associated with older age, childhood sexual abuse, and residing outside of the province's largest city. Transfeminine persons who had genital surgery for gender affirmation were less likely to be abstinent, as compared to those who were living in their felt gender without surgery. Transphobic harassment and higher levels of trans-related sexual body image worries were also associated with sexual inactivity, as was reduced sexual satisfaction. Implications for research and clinical practice are discussed.

AB - PRIMARY OBJECTIVE: This study aimed to investigate the effect of intravenous saline administration on orthostatic hypotension (OH) during head up tilt (HUT) and the change in the renin-angiotensin-aldosterone system before and after HUT in patients with severe acquired brain injury (ABI). RESEARCH DESIGN: The study is designed as an observational study. METHODS AND PROCEDURES: Fourteen patients with ABI, low level of consciousness and OH were monitored before, during and after HUT with non-invasive beat-to-beat blood pressure measurement, and transcranial Doppler determination of middle cerebral artery blood flow velocity. Blood samples were collected before and after two HUT sessions separated by 1 hour and saline was administered in between. MAIN OUTCOMES AND RESULTS: Patients' ability to stand upright did not change after saline administration due to OH. The patients showed signs of reduced cerebral autoregulation at both HUT sessions. The patients had a significant lower level of renin and angiotensin II but not aldosterone. CONCLUSIONS: Patients with severe ABI and OH demonstrate no improvement in standing time with reduced plasma renin and angiotensin II after two HUT sessions and 1 hour fluid administration. Research focusing on the ability to retain fluid after bed rest is warranted. PMID- 29190149 TI - Teacher Perspectives of Interdisciplinary Coteaching Relationships in a Clinical Skills Course: A Relational Coordination Theory Analysis. AB - : Phenomenon: Interdisciplinary coteaching has become a popular pedagogic model in medical education, yet there is insufficient research to guide effective practices in this context. Coteaching relationships are not always effective, which has the potential to affect the student experience. The purpose of this study was to explore interdisciplinary coteaching relationships between a physician (MD) and social behavioral scientist (SBS) in an undergraduate clinical skills course. We aimed to gain an in-depth understanding of what teachers perceive as influencing the quality of relationships to begin to construct a framework for collaborative teaching in medical education. APPROACH: A qualitative study was conducted consisting of 12 semistructured interviews (6 MD and 6 SBS) and 2 monodisciplinary focus groups. Sampling was purposive and aimed at maximal variation from among 64 possible faculty. The data were analyzed using the constant comparative method to develop a grounded theory. FINDINGS: Five major themes resulted from the analysis that outline a framework for interdisciplinary coteaching: respect, shared goals, shared knowledge and understanding, communication, and complementary pairings. Insights: The first 4 themes align with elements of relational coordination theory, an organizational theory of collaborative practice that describes how work roles interact. The complementary pairings extend this theory from work roles to individuals, with unique identities and personal beliefs and values about teaching. Prior studies on coteaching have not provided a clear linkage to theory. The conceptual framework helps suggest future directions for coteaching research and has practical implications for administrative practices and faculty development. These findings contribute to the sparse research in medical education on interdisciplinary coteaching relationships. PMID- 29190151 TI - The effect of repeated light-dark shifts on uterine receptivity and early gestation in mice undergoing embryo transfer. AB - Female shift workers are at increased risk for negative reproductive outcomes, and animal evidence suggests that manipulation of the light-dark cycle is detrimental to early gestation in female mice. Specifically, failure of implantation may be responsible for these findings. The objective of this study was to better delineate which reproductive processes are vulnerable to detrimental effects of maternal circadian disturbance. We exposed mice undergoing embryo transfer to repetitive phase advances of the photoperiod. Embryos were derived from donor sperm and eggs from mice living in normal light-dark conditions to isolate the effects of photoperiod disruption on uterine receptivity and early gestation. Twenty-eight mice receiving embryo transfer underwent an experimental light-dark condition (advance of lights on and lights off by 6 hours every 4 days). Twenty-eight mice remained in a normal light-dark condition. Animals lived in their assigned light-dark condition beginning 2 weeks prior to embryo transfer and ending the day of uterine necropsy (post-coitus day 14.5). Wilcoxon-Mann-Whitney test demonstrated no significant differences between control and experimental light-dark conditions in pups (Z=0.10, p=.92), resorptions (Z=0.20, p=.84), or implantations (Z=-0.34, p=.73). Pup and placental weights were similar between groups. In this investigation, uterine receptivity and maintenance of early gestation were preserved despite recurrent phase advances in photoperiod. This finding, in the context of the current literature, suggests that the negative effects of circadian disruption are mediated by reproductive processes upstream of implantation. PMID- 29190152 TI - Attribution Patterns in Women With and Without Orgasmic Difficulties. AB - People with sexual problems are more likely to attribute negative sexual experiences to themselves, in contrast with sexually functional individuals who attribute negative sexual experiences to external factors such as the circumstance or situation. We investigated attribution patterns in women reporting difficult or absent orgasm-a group only minimally investigated in this regard-to determine whether they differed from women without orgasmic problems. Using an internet-based approach, we compared attribution responses of 376 women with orgasmic difficulty with 367 women without orgasmic difficulty to five sexual scenarios, two presenting positive sexual experiences and three presenting negative sexual experiences. Women with orgasmic difficulty were more likely to take blame for any negative sexual experience, including ones not related to orgasmic difficulty. They were also more likely to attribute responsibility to their partner's lack of skill, whereas orgasmic women attributed negative outcomes more to circumstance. Women with orgasmic difficulty were also less likely to assume credit or responsibility for positive sexual experiences. Differences between orgasmic and non-orgasmic groups persisted or were augmented when age and arousal difficulty were controlled. These results emphasize the stark contrast in the way women with and without orgasmic problems approach sexual situations and suggest several therapeutic strategies. PMID- 29190153 TI - Cognitive function and participation in children and youth with mild traumatic brain injury two years after injury. AB - BACKGROUND: 10-20% of children and youth with mild traumatic brain injury (mTBI) suffer from long-term cognitive impairments with, supposedly, a negative impact on most domains of functioning. OBJECTIVES: To describe cognitive functioning and participation in children and youth two-years post-mTBI and to determine associated risk factors. METHODS: Cross-sectional study among 73 patients (aged 6 22 years), hospital diagnosed with mTBI. Linear regression modelling was used to investigate the effect of potential predictors on cognitive functioning as measured with a neuropsychological assessment (NPA), two-years post-injury. Extent of participation was assessed using the Child and Adolescent Scale of Participation and correlation analysis was conducted to examine its association with level of cognitive functioning. RESULTS: 7-15% of all participants had impaired cognitive functions, especially in the domains of processing speed, inhibitory control, cognitive flexibility, visuospatial constructional ability and visuospatial memory. Lower level of education and pre-injury cognitive problems were predictive for a lower level of long-term cognitive functioning. Slower inhibition speed, impaired visuospatial and verbal working memory were associated with reduced participation. DISCUSSION AND CONCLUSIONS: Persisting cognitive problems two years after mTBI were mostly related to the lower level of education and to pre-injury cognitive problems. Although participation of the patients was reported by parents to be relatively high, slower inhibition speed, impaired visuospatial and verbal working memory were associated with reduced participation. PMID- 29190154 TI - In vitro anti-inflammatory activity of spherical silver nanoparticles and monodisperse hexagonal gold nanoparticles by fruit extract of Prunus serrulata: a green synthetic approach. AB - Recently, green metal nanoparticles have received global attention owing to their economical synthesis, biocompatible nature, widespread biomedical and environmental applications. Current study demonstrates a sustainable approach for the green synthesis of silver nanoparticles (P-AgNPs) and gold nanoparticles (P AuNPs) from P. serrulata fresh fruit extract. The silver and gold nanoparticles were synthesized in a very rapid, efficient and facile manner, within 50 min and 30 s at 80 degrees C, respectively. The nanoparticles were characterized by using visual observation, UV-Vis, FE-TEM, EDX, elemental mapping, FT-IR, XRD and DLS, which confirmed the formation of monodispersed, crystalline and stable nanoparticles. Further, we explored these nanoparticles for anti-inflammatory activity through inhibition of downstream NF-kappaB activation in macrophages (RAW264.7). We demonstrated that the nanoparticles reduced expression of inflammatory mediators such as nitric oxide (NO), prostaglandin E2 (PEG2), inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) was attenuated in lipopolysaccharide (LPS)-induced RAW264.7 cells. Furthermore, nanoparticles significantly suppressed LPS-induced activation of NF-kappaB signalling pathway via p38 MAPK in RAW 264.7 cells. To the best of our knowledge, this is the first report on the efficient green synthesis of P-AgNPs and P-AuNPs using P. serrulata fresh fruit extract and its in vitro anti-inflammatory effects. Collectively, our results suggest that P. serrulata fresh fruit extract is a green resource for the eco-friendly synthesis of P-AgNPs and P-AuNPs, which further can be utilized as a novel therapeutic agent for prevention and cure of inflammation due to their biocompatible nature. PMID- 29190155 TI - Purified Dry Paullinia cupana (PC-18) Extract for Chemotherapy-Induced Fatigue: Results of Two Double-Blind Randomized Clinical Trials. AB - Fatigue is frequent among oncologic patients. Unpurified Paullinia cupana dry extract showed encouraging results for chemotherapy-induced fatigue in our previous studies. We report two randomized, double-blind studies with a standardized dry purified Paullinia cupana extract named PC-18. For both studies, we recruited early breast cancer patients who had an increase in their fatigue scores after their first cycle of adjuvant chemotherapy. In the first study, we compared an oral dose of 37.5 mg of PC-18 twice daily with placebo. In the second study, we examined PC-18 at either 7.5 or 12.5 mg orally twice daily versus placebo. In both studies, PC-18 was not superior to placebo as assessed by both Chalder and Brief Fatigue Inventory (BFI) fatigue questionnaires, probably reflecting unexpectedly good placebo antifatigue activity. Since all capsules employed in both studies contained about 100 mg of magnesium silicate as an excipient, we retrospectively evaluated frozen serum samples from the second study and found a significant increase in magnesium levels after patients received placebo. By multivariate analysis, higher prerandomization magnesium levels and higher BFI scores together with the use of a 12.5 mg dose of PC-18 all correlated significantly with higher posttreatment BFI scores. We observed no significant toxicities in any of the trials. We conclude that the absence of differences between PC-18 and placebo may be due to the unexpectedly high antifatigue activity of the placebo in these studies. Further studies evaluating the role of magnesium supplementation for chemotherapy-induced fatigue are needed. PMID- 29190156 TI - Medication-assisted treatment for youth with opioid use disorder: Current dilemmas and remaining questions. AB - The prevalence of risky opioid use, opioid use disorder, and related harms continue to rise among youth (adolescents and young adults age 15-25) in North America. With an increasing number of opioid overdoses, there remain significant barriers to care for youth with opioid use disorder, and there is an urgent need to expand evidence-based care for treatment of opioid use disorder among this population. Based on the extensive literature on treatment of opioid use disorder among adults, medicated-assisted treatment is likely to be an important or even essential component of treatment of opioid use disorder for most youth. In this article, we outline the current dilemmas and questions regarding the use of medication-assisted treatment among youth with opioid use disorder and propose some potential solutions based on the current evidence. PMID- 29190157 TI - Factors influencing secondary care pharmacist and nurse independent prescribers' clinical reasoning: An interprofessional analysis. AB - In the United Kingdom, pharmacist and nurse independent prescribers are responsible for both the clinical assessment of and prescribing for patients. Prescribing is a complex skill that entails the application of knowledge, skills, and clinical reasoning to arrive at a clinically appropriate decision. Decision making is influenced and informed by many factors. This study, the first of its kind, explores what factors influence pharmacist and nurse independent prescribers during the process of clinical reasoning. A think-aloud methodology immediately followed by a semi-structured interview was conducted with 11 active nurse and 10 pharmacist independent prescribers working in secondary care. Each participant was presented with validated clinical vignettes for the think-aloud stage. Participants chose the clinical therapeutic areas for the vignettes, based on their self-perceived competencies. Data were audio-recorded, transcribed verbatim, and a constant-comparative approach was used for analysis. Influences on clinical reasoning were broadly categorised into themes: social interaction, intrinsic, and contextual factors. These themes showed that intrinsic, sociocultural, and contextual aspects heavily influenced the clinical reasoning processes of prescribers. For example, prescribers were aware of treatment pathways, but chose to refer patient cases to avoid making the final prescribing decision. Exploration of this behaviour in the interviews revealed that previous experience and attitudes such as confidence and cautiousness associated with responsibility were strong influencers within the decision-making process. In addition, strengthening the professional identity of prescribers could be achieved through collaborative work with interprofessional healthcare teams to orient their professional practice from within the profession. Findings from this study can be used to inform the education, training, and practice of independent prescribers to improve healthcare services by improving their professional and interprofessional development. PMID- 29190158 TI - Integrating Interprofessional Education and Cultural Competency Training to Address Health Disparities. AB - PROBLEM: Many U.S. medical schools have accreditation requirements for interprofessional education and training in cultural competency, yet few programs have developed programs to meet both of these requirements simultaneously. Furthermore, most training programs to address these requirements are broad in nature and do not focus on addressing health disparities. The lack of integration may reduce the students' ability to apply the knowledge learned. Innovative programs that combine these two learning objectives and focus on disenfranchised communities are needed to train the next generation of health professionals. INTERVENTION: A unique interprofessional education program was developed at the University of Arkansas for Medical Sciences Northwest. The program includes experiential learning, cultural exposure, and competence-building activities for interprofessional teams of medicine, nursing, and pharmacy students. The activities include (a) educational seminars, (b) clinical experiential learning in a student-led clinic, and (c) community-based service-learning through health assessments and survey research events. CONTEXT: The program focuses on interprofessional collaboration to address the health disparities experienced by the Marshallese community in northwest Arkansas. The Marshallese are Pacific Islanders who suffer from significant health disparities related to chronic and infectious diseases. OUTCOME: Comparison tests revealed statistically significant changes in participants' retrospectively reported pre/posttest scores for Subscales 1 and 2 of the Readiness for Interpersonal Learning Scale and for the Caffrey Cultural Competence in Healthcare Scale. However, no significant change was found for Subscale 3 of the Readiness for Interpersonal Learning Scale. Qualitative findings demonstrated a change in students' knowledge, attitudes, and behavior toward working with other professions and the underserved population. LESSONS LEARNED: The program had to be flexible enough to meet the educational requirements and class schedules of the different health professions' education programs. The target community spoke limited English, so providing interpretation services using bilingual Marshallese community health workers was integral to the program's success. PMID- 29190159 TI - Performance of Bio-Occlusive Dressing as Barrier Protection from Presurgical Chlorhexidine Skin Preparation. AB - : Purpose/Aim of the study: Chlorhexdine has been shown to provide excellent and cost-effective presurgical antisepsis. However, standard presurgical concentrations of chlorhexidine (2-4%) are known to cause ocular injury, even in cases in which a bio-occlusive dressing (TegadermTM) was applied beforehand to the closed eye. MATERIALS AND METHODS: Three experiments were conducted to assess the barrier performance of TegadermTM to chlorhexidine skin prep in vitro and on non-ocular skin. The experiments used water as a control group. RESULTS: In the first in vitro experiment, the chlorhexidine group showed penetration at the edges of the TegadermTM at 5 minutes while the water (control) group never penetrated the TegadermTM. A subsequent experiment testing the central permeability of the tegaderm showed it to be impermeable to both chlorhexidine and water after 90 minutes. In the in vivo experiment, the chlorhexidine group showed penetration at 10 minutes, while the water (control) group never penetrated the TegadermTM. CONCLUSIONS: These data suggest TegadermTM is permeable at the edges to chlorhexidine but not water. Based on this, along with reports of ocular injury from chlorhexidine skin preparation of the head despite prior application of TegadermTM over the eyes, we advise against using bio occlusive adhesive dressing to protect the ocular surface from chlorhexidine exposure. We suggest an alternative presurgical antiseptic agent such as povidone iodine be employed whenever possible. PMID- 29190160 TI - Clinical Profile, Ultra-Wide-Field Fluorescence Angiography Findings, and Long Term Prognosis of Uveitis in Tubulointerstitial Nephritis and Uveitis Syndrome at One Tertiary Medical Institute in China. AB - PURPOSE: To analyze the clinical features and long-term prognosis of uveitis in tubulointerstitial nephritis and uveitis (TINU) syndrome in a cohort of Chinese patients. METHODS: A total of 32 patients with TINU syndrome between 2000 - 2016 were analyzed retrospectively. RESULTS: Mild anterior inflammation was observed in all cases. Ultra-wide-field fluorescence angiography (UWFA) was conducted on 13 patients, and peripheral vascular leakage was observed in 22/26 eyes (84.62%) compared with active anterior chamber inflammation in 13/26 eyes (50%). Three patients received increased corticosteroid dosage therapy on their first episode of uveitis guided by UWFA had stopped steroids without recurrence. CONCLUSION: The uveitis in TINU syndrome was mild. Corticosteroids were efficient in most cases, but a slower tapering and long-term treatment were required. UWFA is sensitive in detecting the activity of uveitis and might be useful in monitoring disease progression. Complete withdrawal of medication was difficult to achieve in some cases.

PMID- 29190162 TI - Redefining treatment failure for pediatric acute leukemia in the era of minimal residual disease testing. AB - Technologies for the detection of minimal residual disease (MRD) in leukemia and our understanding of the prognostic implications of MRD at different phases of treatment have significantly improved over the past decade. As a result, definitions of treatment failure based on bone marrow morphology by light microscopy are becoming increasingly inadequate for clinical care and trial design. In addition, novel therapies that may have increased efficacy and decreased toxicity in the setting of MRD compared to overt disease are changing clinical practice and challenging investigators to redefine treatment failure, the role of disease surveillance in remission, and clinical trial eligibility in the era of MRD. PMID- 29190165 TI - Challenging Treatment of Ocular Surface Squamous Neoplasia in Patients with Atopic Disease. AB - PURPOSE: Few studies have described ocular surface squamous neoplasia (OSSN) and its association with atopic diseases and there is no consensus on the course of OSSN in atopic patients. We thereby report three patients with atopy and OSSN. METHODS: Retrospective case series. RESULTS: Three male patients with mean age of 73 presented with OSSN and history of atopy treated with immunosuppressant therapy. Their histories included atopic dermatitis and keratoconjunctivitis. All patients had treatment complicated by multiple surgeries, recurrences, or advanced disease. The patients initially received medical treatment with topical interferon-alpha-2b (IFNalpha2b). However, all the patients had recurrences and required modification of treatment including topical 5-fluorouracil (5-FU). CONCLUSION: We report on three patients with a history of atopy whose OSSN presentation and course was challenging. Overall, our cases responded better to topical 5-fluorouracil compared to topical interferon-alpha-2b, but recurrences were common. These patients may benefit from more aggressive and long-term treatment. PMID- 29190164 TI - Investigating the biology of relapsed acute leukemia: Proceedings of the Therapeutic Advances for Childhood Leukemia & Lymphoma (TACL) Consortium Biology Working Group. AB - During the 2016 Therapeutic Advances for Childhood Leukemia & Lymphoma (TACL) Consortium investigators' meeting (Los Angeles, CA), a Biology Working Group was established to support the consortium's mission of developing innovative therapies for currently incurable childhood leukemias and lymphomas. The charge of the Biology Working Group was to address how TACL could advance biological investigations of pediatric relapsed/refractory hematologic malignancies while undertaking forward-looking therapeutic trials. To this end, the TACL Biology Committee was established to provide the scientific platform needed to further develop preclinical and translational studies that will advance the understanding and treatment of relapsed and refractory disease. The Biology Committee will focus on ensuring state-of-the-art studies that address biological components of early phase clinical trials, and developing a central biology bank of materials from these early phase trials for interrogations into the mechanisms of disease resistance. PMID- 29190166 TI - Non-alcoholic fatty liver disease (NAFLD) models in drug discovery. AB - INTRODUCTION: The progressive disease spectrum of non-alcoholic fatty liver disease (NAFLD), which includes non-alcoholic steatohepatitis (NASH), is a rapidly emerging public health crisis with no approved therapy. The diversity of various therapies under development highlights the lack of consensus around the most effective target, underscoring the need for better translatable preclinical models to study the complex progressive disease and effective therapies. Areas covered: This article reviews published literature of various mouse models of NASH used in preclinical studies, as well as complex organotypic in vitro and ex vivo liver models being developed. It discusses translational challenges associated with both kinds of models, and describes some of the studies that validate their application in NAFLD. Expert opinion: Animal models offer advantages of understanding drug distribution and effects in a whole body context, but are limited by important species differences. Human organotypic in vitro and ex vivo models with physiological relevance and translatability need to be used in a tiered manner with simpler screens. Leveraging newer technologies, like metabolomics, proteomics, and transcriptomics, and the future development of validated disease biomarkers will allow us to fully utilize the value of these models to understand disease and evaluate novel drugs in isolation or combination. PMID- 29190167 TI - Engaging the Transgender Community to Improve Medical Education and Prioritize Healthcare Initiatives. AB - : Phenomenon: Transgender patients experience discrimination, limited access to care, and inadequate provider knowledge in healthcare settings. Medical education to address transgender-specific disparities is lacking. Research that engages transgender community members may help address health disparities by empowering patients, increasing trust, and informing medical curricula to increase competence. APPROACH: A 2015 Community Forum on Transgender Health Care was hosted at the University of Louisville School of Medicine, which included healthcare professionals and transgender community members to facilitate dialogue among mixed-participant groups using a World Cafe model. Fifty-nine participants discussed the status of transgender healthcare and made recommendations for local improvements. A follow-up survey was administered to 100 individuals, including forum participants and their referrals. The forum discussion and survey responses were analyzed to determine common perceptions of transgender healthcare, priorities for improvement interventions, and themes to inform curriculum. FINDINGS: The community forum discussion showed that local transgender care is overwhelmingly underdeveloped and unresponsive to the needs of the transgender community. The follow-up survey revealed that priorities to improve transgender care included a multidisciplinary clinic for lesbian, gay, bisexual, and transgender (LGBT) patients, an LGBT-friendly network of physicians, and more training for providers and support staff. This mutually constructive engagement experience influenced reform in undergraduate curricula and continuing education opportunities. Insights: Community engagement in healthcare disparities research can cultivate improbable discussions, yield innovative insight from marginalized populations, and build relationships with community members for future collaborations and interventions. Societal acceptance of transgender identities, which could be promoted through healthcare providers, could stimulate significant progress in transgender healthcare. Supplemental educational interventions for practicing physicians will improve the current conditions of transgender healthcare, but a comprehensive medical school curriculum specifically for transgender health that includes interactions between the transgender community and medical students could be particularly impactful. PMID- 29190168 TI - The effect of anti-thyroid antibodies positivity on children with primary immune thrombocytopenia. AB - Primary immune thrombocytopenia (ITP) is the most common cause of acquired thrombocytopenia in children. Anti-thyroid antibodies (aTA) have previously been found to be present in various autoimmune diseases. Our aim was to study the effect of aTA positivity (which are anti-thyroid peroxidase (aTPo) and/or anti thyroglobulin (aTg)) on children with primary immune thrombocytopenia and their relation to treatment response. Sixty-one children with primary ITP were enrolled in the present study. They were further subdivided into: ND&P group (newly diagnosed and persistent) and chronic ITP group. Seventy-five apparently healthy children were enrolled as control group. aTPo and aTg antibodies were significantly higher and more frequently positive in all children with ITP and in each ITP group than the control group (P <.05 in all). But, there were no statistically significant differences between the two ITP subgroups (P >.05). aTA positive children with ITP had significantly lower platelet count: at the start of treatment (P =.009), after receiving methylprednisolone or intravenous immunoglobulin (P =.02) and at one month follow-up (P =.003) than aTA negative children with ITP. Lastly, aTA positive children had more relapses (P =.03), continued more frequently to have relapses after one year in the ND&P group (P =.02) and required immunosuppressive therapy more frequently in the chronic ITP group (P =.005). PMID- 29190169 TI - TACL'ing supportive care needs in pediatric early phase clinical trials for acute leukemia: A report from the therapeutic advances in childhood leukemia & lymphoma (TACL) consortium supportive care committee. AB - A Supportive Care Committee was recently developed within the Therapeutic Advances in Childhood Leukemia & Lymphoma (TACL) Consortium. This was substantiated by the significantly high rate of serious adverse events (SAE) (CTCAE Grade >=3 toxicity) experienced by patients with relapse/refractory acute leukemia enrolled on our phase I trials. Such treatment-related toxicity has resulted in patients being removed from study and thus potentially not receiving clinical benefit from the novel therapy. In addition, increased treatment-related toxicity may compromise new agents from moving forward in their clinical development. To address these challenges, TACL initiated a Supportive Care Committee to help mitigate the treatment-related toxicity risk that exists in heavily pre-treated patients with relapse/refractory leukemia. This manuscript reviews the mission of the TACL Supportive Care Committee presented at the 2016 TACL Investigators' Meeting (Los Angeles, CA) and the future direction in providing enhanced supportive care guidelines for all TACL studies. PMID- 29190170 TI - The Role of Dexamethasone Implant in the Management of Tubercular Uveitis. AB - PURPOSE: To study the safety and efficacy of intravitreal injection of dexamethasone implant in the management of posterior segment involvement in tubercular uveitis (TBU). METHODS: In this study, retrospective analysis of safety and efficacy of intravitreal injection of dexamethasone implant for various indications such as cystoid macular edema (CME), vitritis, or paradoxical worsening in TB-related intermediate uveitis, retinal vasculitis, and multifocal serpiginoid choroiditis (MSC) was performed. RESULTS: The study included 17 patients (19 eyes; 7 males). IOP increased from 14.88 +/- 2.68 mm Hg to 16.4 +/- 5.82 mm Hg (p = 0.18) at 3 months. BCVA improved from 0.37 +/- 0.35 to 0.27 +/- 0.21 at 3 months (p = 0.03). CME resolved at 3 months and two patients with paradoxical worsening showed resolution within 1 month. CONCLUSION: Intravitreal dexamethasone implant is safe and efficacious as an adjunct to ATT in reducing the central macular thickness, vitritis, and progression of choroiditis lesions in paradoxical worsening of MSC. PMID- 29190171 TI - Associations with retinal vascular occlusions in a diverse, urban population. AB - PURPOSE: Retinal vascular occlusions can lead to sudden and permanent visual impairment or blindness. Few epidemiological studies on retinal vascular occlusions have been conducted, especially on diverse populations. METHODS: This is a retrospective case-control study of all incident retinal vascular occlusions occurring during a three and one-half year study period at Montefiore Medical Center, capturing all potential cases by diagnosis codes. Patients with retinal venous occlusions (RVO) and retinal arterial occlusions (RAO) were analyzed separately and compared to age-matched control groups. RESULTS: All potential charts (n = 700) were reviewed, confirming 214 RVO and 35 RAO incident cases. In multivariable analyses, RVO was associated with type 2 diabetes mellitus (OR 2.41, p < 0.001), history of cerebrovascular accident (OR 2.14, p = 0.011), hypertension (OR 1.83, p = 0.004), glaucoma (OR 6.91, p < 0.001), black race (OR 3.72, p < 0.001), and male gender (OR 2.19 p < 0.001). RAO was significantly associated with current and former smoking combined (OR 8.95, p = 0.021) and male gender (OR 2.56, p = 0.038). CONCLUSION: Cardiovascular risk factors and glaucoma are reaffirmed as significant predictors of retinal vascular occlusions in a diverse patient population. Retinal vascular occlusions are more common in certain races and ethnicities, and further study into this may help identify high risk individuals based on demographics. PMID- 29190172 TI - Implementation of a "real world" School-Based Asthma Therapy program targeting urban children with poorly controlled asthma. AB - OBJECTIVE: Describe implementation and clinical impact of a "real world" School Based Asthma Therapy (SBAT) Program serving an urban, largely Medicaid population in a large midwestern city in the United States. METHODS: A retrospective, descriptive evaluation of SBAT was conducted. Students were referred by school nurses or providers, enrolled throughout the year, and could reenroll in subsequent years. A total of 286 students participated in the 2015-2016 school year. Kruskal-Wallis nonparametric testing compared Asthma Control TestTM (ACT) scores from enrollment (anytime between 2013 and 2015) to 2015-2016 for 198 students; and pre- and postenrollment asthma-related emergency department (ED), inpatient, and critical care (pediatric intensive care unit or PICU) utilization rates (events/student/year) for 98 students enrolled for a full year. RESULTS: SBAT participation grew from 17 to 131 schools and from 38 to 268 students between 2013-2014 and 2015-2016. Mean ACT scores increased from 16.2 (SD = 4.89) to 21.37 (SD = 3.41) (K-W chi2 = 35.45, p = 0.008). Healthcare utilization rates from 1-year preenrollment to 1-year postenrollment decreased for ED (0.91-0.44; K W chi2 = 18.61, p = 0.0002) and Inpatient (0.38-0.10; K-W chi2 = 7.68, p = 0.02). Reduction in PICU (0.27-0.02) was not statistically significant. CONCLUSIONS: SBAT, modeled after programs shown in controlled trials to improve asthma health markers ( 1-3 ), was successfully implemented in economically challenged, urban schools. Rapid growth and patient reenrollment reflect program acceptance by schools, providers, and caregivers. Improved ACT scores and healthcare utilization supported program efficacy. SBAT could be one solution to improved asthma control in underserved school-aged pediatric patients. PMID- 29190173 TI - Detection of Bacteria Colonizing Titanium Spinal Implants in Children. AB - BACKGROUND: Bacterial colonization of spinal implants may cause severe complications in patients with early-onset scoliosis. Correct diagnosis and detection of microbiologic formation is crucial to prevent delayed infections caused by bacterial colonization. The purposes of this study were to estimate the rate and risk factors of colonization of vertical expandable prosthetic titanium rib (VEPTR) implants in children and to compare the different methods for detecting microbiologic formation on the spinal implants. METHODS: We evaluated prospectively a group of 42 children with spinal deformities with an overall of 95 lengthening surgeries and applied different methods to detect potential bacterial colonization of VEPTR implants: swab of the implant, swab with culture of tissue, analysis of the removed lock, polymerase chain reaction (PCR), and confocal microscopy. Potential risk factors were evaluated. RESULTS: Of 42 patients, 17 (40%) were rated positive for bacterial colonization with Propionibacterium acnes and coagulase-negative staphylococci being the most commonly found bacteria. Risk factors for colonization were increasing age, body height, and weight. The swab with culture of removed tissue yielded most positive results, whereas direct microscopy and PCR were the least sensitive detection methods. Furthermore, commonly used infectious blood parameters were inconclusive. CONCLUSIONS: Although the impact of bacterial colonized implants on the health of the patients is not fully elucidated, clinicians aim for prevention of microbiologic formation on implanted devices. Therefore, reliable, inexpensive, and easy to apply diagnostic tools are indispensable to detect colonization. Based on our data, the swab together with tissue culture has the potential to become the method of choice for future diagnosis. PMID- 29190174 TI - Same-Sex Friendship, School Gender Composition, and Substance Use: A Social Network Study of 50 European Schools. AB - BACKGROUND: Other-sex friendship (girls with boy friends, boys with girl friends) has been associated with substance use, but how the gender composition of schools influences substance use has not been known. OBJECTIVES: We analyzed the influence of other-sex friendship on substance use and took into account the proportion of each gender group at the schools, and hypothesized that other-sex friendship is associated with higher levels of substance use and that schools with a majority of males have higher levels of use than female-majority schools. METHODS: In 2013, a social network survey was carried out in six European cities. In each city, schools were selected and 11,015 adolescents (aged 14-16) were recruited (participation rate = 79.4%). We collected data on smoking, binge drinking, cannabis use, and peer group composition. RESULTS: Other-sex friendship was associated with smoking, binge drinking, and cannabis use for girls and with smoking for boys. Substance use was more frequent in schools with a majority of males. Conclusions/Importance: Adolescent girls are best protected from substance use if they are in gender-balanced schools, but in same-sex friendship. This offers new perspectives on gender mixing at school. In schools with a majority of boys, more attention should be paid to girls, and gender-specific health promotion programs should be implemented. This European study is the first to take into account both individual (other-sex friendship) and contextual (gender composition of schools) gender interactions. It confirms previous studies on other-sex friendship, while shedding light on the influence of gender-normative contexts on substance use.

AB - The opioid epidemic is associated with morbidity and mortality, and it has taken a vast toll on American society. While prescription opioid abuse is part of the opioid problem, it is by no means the entirety of it. Opioid abuse appears to have entered a technology-driven new world of clandestine labs all over the globe and many new synthetic analog, counterfeit, and adulterated drugs that arrive via the internet faster than the Drug Enforcement Administration (DEA) can catalog and outlaw them. To deal with opioid abuse, it must be recognized that it is more - far more - than a subset of chronic pain patients who become addicted. Indeed, to reduce the opioid epidemic to this population is to misunderstand it. The opioid epidemic involves illicit opioids, counterfeit opioids, new psychoactive substances, diverted opioids, and prescription opioids. The objective of this narrative review is to consider the roles of all substances that contribute to the opioid epidemic in America. PMID- 29190176 TI - Correlation of serum ferritin levels with hepatic MRI T2 and liver iron concentration in nontransfusion beta-thalassemia intermediate patients: A contemporary issue. AB - BACKGROUND: Beta-thalassemia intermediate is a genetic disease that is milder than beta-thalassemia major. The T2* magnetic resonance imaging (MRI) technique is currently the gold standard for iron load detection. However, it is expensive and needs an expert radiologist to report findings. Therefore, we conducted this study to determine an optimal cut-off value of ferritin in proportion to T2 MRI of liver and measurement of liver iron concentration for early detection of hepatic iron overload in Beta-thalassemia intermediate patients. METHODS: This cross-sectional study was conducted on 108 patients with Beta-thalassemia intermediate who referred to tertiary hospital, Shiraz, Iran. Serum ferritin, hepatic T2 MRI, and liver iron concentration were assessed. Receiver operator characteristic was used to determine the sensitivity and specificity of cut-off value. RESULTS: Serum ferritin levels showed a statistically significant negative correlation with T2 hepatic MRI (r = -0.290, p value =.003) and positive correlation with liver iron concentration (r = 0.426, p value <.001) in the patients with Beta-thalassemia intermediate. According to the receiver operator characteristic, the best cut-off value for ferritin to show early diagnosis of liver iron overload was 412 ng/mL. Calculated sensitivities and specificities were 0.78 and 0.82 for T2 MRI and 0.76 and 0.86 for liver iron concentration, respectively. CONCLUSION: Serum ferritin levels of around 450 ng/mL might be considered as a cut-off point to evaluate hepatic iron overload before using expensive, not readily available T2 MRI. This level of serum ferritin could be considered for starting iron chelation therapy in patients with Beta-thalassemia intermediate in areas where T2 MRI is not available. PMID- 29190178 TI - Transanal Total Mesorectal Excision in Lower Rectal Cancer: Comparison of Short Term Outcomes with Conventional Laparoscopic Total Mesorectal Excision. AB - BACKGROUND: Transanal total mesorectal excision (TaTME) is a novel technique to treat rectal cancer and also to obtain good-quality specimens. This study investigated the clinical results and perioperative and pathological outcomes of TaTME in lower rectal cancer treatment in comparison with laparoscopic total mesorectal excision (LaTME). METHODS: During January 2014 to May 2017, all consecutive patients with lower rectal cancer who underwent TaTME were identified. This cohort study was matched for age, gender, American Society of Anesthesiology (ASA) score, and clinical staging with a cohort of patients who underwent conventional LaTME. RESULTS: A total of 46 patients were analyzed in both groups. There were no significant differences in baseline characteristics between the groups. The estimated blood loss, duration of operation, and postoperative complications were also not different between both groups. Regarding pathological outcomes, no patients with circumferential margin (CRM) <1 mm were observed in the TaTME group compared to 4 patients with CRM <1 mm in the LaTME group (P = .037). CONCLUSION: TaTME is a safe and feasible procedure in this matched case-control study. TaTME had better pathological outcomes with CRM uninvolvement compared with laparoscopic surgery. PMID- 29190179 TI - Patient-Reported Health-Related Quality-of-Life Assessment at the Point-of-Care with Adolescents and Young Adults with Cancer. AB - PURPOSE: Advances in health-related quality-of-life (HRQL) measurement enable point-of-care assessments. We incorporated the Patient-Reported Outcomes Measurement Information System (PROMIS(r)) Global Health Scale in routine outpatient evaluations of adolescent and young adult (AYA) oncology patients and survivors at two geographically distinct U.S. institutions. METHODS: AYAs (18-39 years old) completed the 10-question PROMIS Global. Summary subscale scores for Global Physical Health (GPH) and Global Mental Health (GMH) were produced using established scoring algorithms (standardized mean = 50, standard deviation = 10). In addition to comparisons by treatment status, associations between lower subscale scores (<45, previously defined as clinically meaningful) and patient characteristics were assessed using two-sample t-tests among those off treatment. RESULTS: Of 147 patients approached, 142 consented. Mean age was 24.6 +/- 5.3 years; 53.5% were male; and 61.3% had hematologic malignancies. Most (76%) were off treatment; 43.0% had treatment complications. While mean GPH and GMH scores did not differ from the standardized population mean (GPH, 49.7 +/- 8.8, p = 0.73; GMH, 50.5 +/- 9.3, p = 0.55), mean GPH scores were lower among those on treatment (44.3 +/- 9.0) than off treatment (51.5 +/- 8.1, p < 0.0001). There was no difference in GMH scores by treatment status. Among those off treatment, 26.9% of GPH and 22.2% of GMH scores were <45. The only factor associated with lower GPH scores was treatment complications; no factors were associated with lower GMH scores. CONCLUSION: Point-of-care HRQL assessment with AYAs is feasible. Among patients off treatment, GPH scores were lower for patients with treatment complications. Further research is needed to understand factors associated with lower GMH scores in this AYA oncology population. PMID- 29190180 TI - Daily-level Associations between Negative Mood, Perceived Stress, and College Drinking: Do Associations Differ by Sex and Fraternity/Sorority Affiliation? AB - BACKGROUND: Individuals experiencing elevated negative mood and stress may drink to self-medicate, yet daily-level evidence for these associations is mixed. OBJECTIVE: To clarify daily associations between negative mood and perceived stress with alcohol use among high-risk college students and test whether these associations may vary by same-day versus next-day drinking, sex, and fraternity/sorority affiliation. METHODS: Frequently drinking college students (n = 347) participated in a daily diary study, which included daily morning and evening assessments that occurred for two weeks in four consecutive academic quarters. Multilevel zero-inflated Poisson regressions were conducted to examine the effects of daily negative mood and perceived stress on same-day and next-day drinking. RESULTS: Students with higher average negative mood and perceived stress across the sampled days reported a lower likelihood of drinking. Examination of daily-level associations showed that on days students experienced elevated negative mood and perceived stress, they were less likely to drink any alcohol the same day. However, days with elevated negative mood were associated with greater alcohol use the next day. Tests of cross-level interactions indicated that four daily-level associations between higher negative mood or perceived stress and reductions in drinking were found to be significant among females and students unaffiliated with fraternity/sorority only. Conclusions/Importance: Among high-risk college drinkers, negative mood and perceived stress were associated with decreased risk of drinking, particularly among females and students unaffiliated with fraternity/sorority. Daily elevations in negative mood may lead to drinking on a subsequent day and the reason for this lagged effect warrants future research. PMID- 29190181 TI - Identifying opportunities to bridge disparity gaps in curing childhood cancer in Malawi: Malignancies with excellent curative potential account for the majority of diagnoses. AB - The majority of African children with cancer die without access to resources. We describe efforts to build a public treatment program with curative intent for childhood cancer in Lilongwe, Malawi despite severe limitations in diagnostic and therapeutic resources. We retrospectively analyzed a cohort of childhood cancer patients at Kamuzu Central Hospital from 12/2011-6/2013. Consistently available chemotherapeutic agents were limited to cyclophosphamide, vincristine, doxorubicin, bleomycin, methotrexate, and prednisone. Of 258 newly diagnosed childhood malignancies, 17 patients with retinoblastoma were excluded from clinical analyses due to insufficient clinical data. Among the remainder of the cohort (n = 241), 42% were female with median age 8.4 years (range 0.6-17.9). Forty-six (19%) were HIV-infected (42 Kaposi sarcoma, 3 Burkitt lymphoma, 1 Hodgkin lymphoma). The most common clinical presentations were palpable abdominal mass (41%), peripheral lymphadenopathy (33%), and jaw mass (17%). Nearly two thirds of total diagnoses were accounted for by Burkitt lymphoma (n = 74), Kaposi sarcoma (n = 52), Hodgkin lymphoma (n = 21), and Wilms tumor (n = 19). Twelve month overall survival for these 4 most common diagnoses was 54% (95% confidence interval 46-61) versus 19% (95% confidence interval 11-30) for all other diagnoses (median follow-up 19 months). Treatment-related mortality was highest in patients with non-Wilms solid tumors of the abdomen (48% versus 10% for the overall cohort, p < 0.001), while treatment abandonment was highest in patients with bone and soft-tissue sarcomas (29% versus 14% overall, p = 0.05). Childhood cancers with excellent curative potential accounted for the majority of patients, establishing an opportunity to build treatment programs with curative intent despite severe limitations. PMID- 29190182 TI - Checkpoint inhibition in pediatric hematologic malignancies. AB - Immune surveillance comprising of adaptive and innate immune systems is naturally designed to eliminate cancer development; overexpression of inhibitory receptors and their ligands prevent this check and lead to evasion and hence cancer progression and metastasis. The use of tumor-specific monoclonal antibodies (MAbs) targeting these checkpoint regulators is promising and has led to this novel field of cancer immunotherapy. The first antibody directed against cytotoxic T-lymphocyte associated protein 4 (CTLA-4), ipilimumab, showed promising results in clinical trials and was approved by the US Food and Drug Administration (FDA) for the treatment of metastatic melanoma in 2011. Since then, various other immune checkpoint inhibitors are being studied in preclinical and clinical trial phases, targeting programmed-death-1 (PD-1) and its ligand programmed death ligand 1 (PD-L1), T cell lymphocyte activation gene-3 (LAG-3), and others. Results from clinical trials are promising, and currently this approach has proven effective and safe in patients with solid tumors and some hematological malignancies in adults. In general, CTLA-4 and PD-1 inhibitors are well tolerated; however, the augmented immune response enabled by this class of agents is associated with a unique group of side effects called immune-related adverse events (irAEs). Experience in pediatrics using immune checkpoint inhibitors for hematological malignancies is limited to Hodgkin's disease and non Hodgkin's lymphoma as in the ongoing Children's Oncology Group (COG) protocol ADVL1412. Therapeutic advances in childhood leukemia and lymphoma (TACL) consortium will initiate an early phase clinical trial with PD-1 inhibitor nivolumab in relapsed/refractory acute myeloid leukemia (AML) in the next few months. PMID- 29190183 TI - A Long-Term Follow-Up of a New Surgery Method: Laparoscope-Assisted Heart-Shaped Anastomosis for Hirschsprung's Disease. AB - BACKGROUND: Laparoscopic surgery is widely used in the treatment of Hirschsprung's disease (HD). However, constipation and soiling are still the main long-term complications. A new type of anastomosis, which is characterized by a heart-shaped colorectal anastomosis after splitting the posterior rectum wall to 0.5 cm above the dentate line, has been improved by our medical center. The purpose of this study was to determine the long-term effects of laparoscope assisted heart-shaped anastomosis (LHSA) and to compare it with a more generally applied approach, the laparoscope-assisted Soave procedure (LSP). PATIENTS AND METHODS: In this retrospective study, we investigated the symptoms of chronic constipation and soiling in 56 patients after LHSA and 54 patients after LSP between 2005 and 2011. RESULTS: For LHSA, the median age at surgery was 1.4 years (0.2-7.3), and the median follow-up time was 7.1 years (5-11.3). For LSP, the median age at surgery was 1.2 years (0.1-6.2) and the median follow-up time was 7.0 years (5-9.3). Constipation was less frequent after LHSA than after LSP (7.1 versus 22.2%, P = .025), but there was no difference in the frequency of soiling after LHSA compared with that after LSP (8.9 versus 14.8%, P = .339). CONCLUSIONS: The improved anastomosis (LHSA) preserves most of the internal anal sphincter, and the wide anastomosis prevents stenosis as well. In the long-term follow-up results, the incidence of constipation after LHSA declined when compared with that after LSP, and soiling showed a satisfactory result. Our medical center has performed laparotomy-assisted heart-shaped anastomosis since the 1990s and LHSA since the 2000s. Because it is easy to learn and provide good outcomes, many medical centers in China have adopted the heart-shaped anastomosis to treat HD. Using the LHSA method to manage the affected bowel provides satisfactory long-term outcomes, that is, avoiding constipation and soiling. Thus, LHSA may provide a new choice for HD operations. PMID- 29190186 TI - Influence of Speed and Accuracy Constraints on Motor Learning for a Trajectory Based Movement. AB - This study investigated the influences of task constraint on motor learning for a trajectory-based movement considering the speed-accuracy relationship. In the experiment, participants practiced trajectory-based movements for five consecutive days. The participants were engaged in training with time minimization or time-matching constraints. The results demonstrated that the speed-accuracy tradeoff was not apparent or was weak in the training situation. When the participants practiced the movement with a time-minimization constraint, movement errors did not vary, whereas the movement time decreased. With the time matching constraint, the errors decreased as a session proceeded. These results were discussed in terms of the combination of signal-dependent noises and exploratory search noises. It is suggested that updating spatial and temporal factors does not appear to occur simultaneously in motor learning. PMID- 29190187 TI - Characterization of inter-tissue and inter-strain variability of TCE glutathione conjugation metabolites DCVG, DCVC, and NAcDCVC in the mouse. AB - Trichloroethylene (TCE) is a ubiquitous environmental toxicant that is a liver and kidney carcinogen. Conjugation of TCE with glutathione (GSH) leads to formation of nepthrotoxic and mutagenic metabolites postulated to be critical for kidney cancerdevelopment; however, relatively little is known regarding their tissue levels as previous analytical methods for their detection lacked sensitivity. Here, an LC-MS/MS-based method for simultaneous detection of S-(1,2 dichlorovinyl)-glutathione (DCVG), S-(1,2-dichlorovinyl)-L-cysteine (DCVC), and N acetyl-S-(1,2-dichlorovinyl)-L-cysteine (NAcDCVC) in multiple mouse tissues was developed. This analytical method is rapid, sensitive (limits of detection (LOD) 3-30 fmol across metabolites and tissues), and robust to quantify all three metabolites in liver, kidneys, and serum. The method was used to characterize inter-tissue and inter-strain variability in formation of conjugative metabolites of TCE. Single oral dose of TCE (24, 240 or 800 mg/kg) was administered to male mice from 20 inbred strains of Collaborative Cross. Inter-strain variability in the levels of DCVG, DCVC, and NAcDCVC (GSD = 1.6-2.9) was observed. Whereas NAcDCVC was distributed equally among analyzed tissues, highest levels of DCVG were detected in liver and DCVC in kidneys. Evidence indicated that inter-strain variability in conjugative metabolite formation of TCE might affect susceptibility to adverse health effects and that this method might aid in filling data gaps in human health assessment of TCE. PMID- 29190189 TI - Changes in working memory performance in youth following concussion. AB - OBJECTIVE: The purpose of this study was to compare the working memory (WM) performance pre- and post-concussion, and investigate the relationships between performance changes and characteristics such as self-reported symptom scores, number of days post-injury and age at injury in 10-14-year-old youth. METHODS: Twenty-one youth (17 males) aged 10-14 years recruited from the community completed verbal and non-verbal WM tasks pre- and post-concussion. Performance was measured using accuracy and performance errors (false alarms and misses). Pre and post-tests were compared using a Wilcoxon signed rank test, and effect size was determined using matched-pairs rank biserial correlation. RESULTS: Comparisons showed lower verbal WM accuracy at post-test, greater verbal and non verbal WM false alarm errors at post-test, and greater verbal WM miss errors at post-test (all r >= 0.30). Correlations between performance and characteristics revealed associations between younger youth and lower non-verbal WM accuracy and more false alarms at post-test, as well as an association among non-verbal WM miss errors, higher PCS scores and fewer days since injury at post-test. CONCLUSIONS: The current study found lower WM performance in youth following concussion. Furthermore, the findings suggest that false alarm errors may be a useful screening measure acutely post-concussion when assessing WM performance in youth. PMID- 29190188 TI - Biomeasures and mechanistic modeling highlight PK/PD risks for a monoclonal antibody targeting Fn14 in kidney disease. AB - Discovery of the upregulation of fibroblast growth factor-inducible-14 (Fn14) receptor following tissue injury has prompted investigation into biotherapeutic targeting of the Fn14 receptor for the treatment of conditions such as chronic kidney diseases. In the development of monoclonal antibody (mAb) therapeutics, there is an increasing trend to use biomeasures combined with mechanistic pharmacokinetic/pharmacodynamic (PK/PD) modeling to enable decision making in early discovery. With the aim of guiding preclinical efforts on designing an antibody with optimized properties, we developed a mechanistic site-of-action (SoA) PK/PD model for human application. This model incorporates experimental biomeasures, including concentration of soluble Fn14 (sFn14) in human plasma and membrane Fn14 (mFn14) in human kidney tissue, and turnover rate of human sFn14. Pulse-chase studies using stable isotope-labeled amino acids and mass spectrometry indicated the sFn14 half-life to be approximately 5 hours in healthy volunteers. The biomeasures (concentration, turnover) of sFn14 in plasma reveals a significant hurdle in designing an antibody against Fn14 with desired characteristics. The projected dose (>1 mg/kg/wk for 90% target coverage) derived from the human PK/PD model revealed potential high and frequent dosing requirements under certain conditions. The PK/PD model suggested a unique bell shaped relationship between target coverage and antibody affinity for anti-Fn14 mAb, which could be applied to direct the antibody engineering towards an optimized affinity. This investigation highlighted potential applications, including assessment of PK/PD risks during early target validation, human dose prediction and drug candidate optimization. PMID- 29190190 TI - Letters to the Editor. PMID- 29190191 TI - Systemic manifestations of Cuterebra infection in dogs and cats: 42 cases (2000 2014). AB - OBJECTIVE To document clinical signs in cats and dogs with Cuterebra infection, determine the outcome of infected animals, and determine whether Yorkshire Terriers were more commonly affected than other breeds of dogs. DESIGN Retrospective case series. ANIMALS 22 cats and 20 dogs with Cuterebra infection. PROCEDURES Medical records of dogs and cats with Cuterebra infection were reviewed for signalment, history, clinical and laboratory findings, treatment, duration of hospitalization, and outcome. RESULTS Most (16/20 [80%]) of the dogs weighed <= 4.5 kg (10 lb), and Yorkshire Terriers were overrepresented (8/20 [40%]), compared with dogs of other breeds. Ten (50%) dogs and 3 (14%) cats had systemic inflammatory response syndrome at the time of initial evaluation, and 8 (40%) dogs but none of the cats had disseminated intravascular coagulation. The overall mortality rate was 17% (7/42), but was higher for dogs (6/20 [30%]) than cats (1/22 [4.5%]). All 6 dogs that died weighed <= 4.5 kg and had systemic inflammatory response syndrome, disseminated intravascular coagulation, or both. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that Cuterebra infection can cause severe systemic illness in small-breed dogs. Yorkshire Terriers were more commonly affected than were dogs of other breeds and, subjectively at least, appeared to be more likely to develop severe systemic illness. PMID- 29190192 TI - Suspected zonisamide-related anticonvulsant hypersensitivity syndrome in a cat. AB - CASE DESCRIPTION A 2-year-old neutered male domestic shorthair cat was evaluated for sudden onset of cluster seizures. CLINICAL FINDINGS At an emergency clinic, the cat had hyperimmunoglobulinemia and thrombocytopenia. On referral, treatment with levetiracetam, zonisamide, and phenobarbital initially provided good control of cluster seizure activity (attributable to epilepsy of unknow origin). Two weeks later, assessments revealed that serum phenobarbital concentration was within the ideal range but serum zonisamide concentration exceeded the recommended therapeutic range. The dosage of zonisamide was therefore decreased. Four days after dosage reduction, the cat developed generalized lymphadenopathy. Cytologic analysis of lymph node aspirate samples revealed a heterogeneous population of well-differentiated lymphocytes, interpreted as marked reactivity. Although neoplasia could not be ruled out, hypersensitivity to phenobarbital was suspected, and this treatment was discontinued. TREATMENT AND OUTCOME Despite cessation of phenobarbital administration, generalized peripheral lymphadenopathy progressed and hyperglobulinemia and cytopenias developed. These abnormalities resolved after discontinuation of zonisamide administration. The cat remained seizure free with no recurrence of the aforementioned concerns after reinstitution of phenobarbital treatment. CLINICAL RELEVANCE To the authors' knowledge, this is the first reported case of zonisamide-related lymphadenopathy, hyperglobulinemia, and cytopenias in a cat. Anticonvulsant hypersensitivity syndrome is well documented in human medicine, but little information has been published in the veterinary medical literature. Although the effects of anticonvulsant hypersensitivity syndrome in this cat were serious, these effects were reversible with treatment discontinuation. PMID- 29190194 TI - What Is Your Diagnosis? PMID- 29190193 TI - Characterization and comparison of injuries caused by spontaneous versus organized dogfighting. AB - OBJECTIVE To characterize and compare injuries found in dogs involved in spontaneously occurring dogfights with those of dogs used in illegal organized dogfighting. DESIGN Retrospective case-control study. ANIMALS 36 medium-sized dogs evaluated following spontaneous fights with a dog of the same sex and similar weight (medium dog-medium dog [MDMD] fights), 160 small dogs examined following spontaneous fights with a larger dog (big dog-little dog [BDLD] fights), and 62 dogs evaluated after being seized in connection with dogfighting law enforcement raids. PROCEDURES Demographic characteristics and injuries were recorded from medical records. Prevalence of soft tissue injuries in predetermined body surface zones, as well as dental or skeletal injuries, was determined for dogs grouped by involvement in BDLD, MDMD, and organized dogfights. The extent of injuries in each location was scored and compared among groups by 1-factor ANOVA. Patterns of injuries commonly incurred by each group were determined by use of prevalence data. RESULTS Mean extent of injury scores differed significantly among groups for all body surface zones except the eye and periorbital region. Mean scores for dental injuries and rib fractures also differed significantly among groups. Organized fighting dogs more commonly had multiple injuries, particularly of the thoracic limbs, dorsal and lateral aspects of the head and muzzle or oral mucosa, dorsal and lateral aspects of the neck, and ventral neck and thoracic region. CONCLUSIONS AND CLINICAL RELEVANCE To the authors' knowledge, this was the first study to compare injuries incurred during spontaneous and organized dogfighting. Establishing evidence-based patterns of injury will help clinicians identify dogs injured by organized dogfighting and aid in the prosecution of this crime. PMID- 29190195 TI - Puppy socialization practices of a sample of dog owners from across Canada and the United States. AB - OBJECTIVE To identify actions taken by owners to socialize puppies < 20 weeks of age, to determine factors affecting attendance of structured puppy classes, and to examine associations between class attendance and owner response to various undesirable puppy behaviors. DESIGN Cross-sectional study. SAMPLE 296 puppy owners (each with 1 puppy). PROCEDURES Participants completed a survey at enrollment (to gather data regarding owner demographics and puppy characteristics) and again when puppies were 20 weeks of age (to gather information on socialization practices and owner responses to misbehavior and signs of fear in their puppy). Responses were compared between owners that did (attendees) and did not (nonattendees) report attending puppy classes. RESULTS 145 (49.0%) respondents reported attending puppy classes. Class structure differed greatly among respondents. Attendees exposed their puppies to a greater number of people and other dogs than nonattendees as well as to various noises and situations. Puppies of attendees were less likely than puppies of nonattendees to have signs of fear in response to noises such as thunder and vacuum cleaners as well as to crates. Fewer attendees reported use of punishment based discipline techniques than did nonattendees. Almost one-third of puppies received only minimal exposure to people and dogs outside the home during the survey period. CONCLUSIONS AND CLINICAL RELEVANCE A notable number of puppies < 20 weeks of age in this study received few early socialization opportunities, which could lead to behavior problems and subsequent relinquishment. Opportunities exist for veterinarians to serve an important role in educating puppy owners about the importance of early puppy socialization and positive reward training. PMID- 29190196 TI - Clinical and histologic features of acute-onset erythroderma in dogs with gastrointestinal disease: 18 cases (2005-2015). AB - OBJECTIVE To describe the clinical and histologic features of acute erythroderma in dogs with gastrointestinal disease. DESIGN Retrospective case series. ANIMALS 18 dogs with erythroderma and gastrointestinal disease. PROCEDURES Medical records and biopsy specimens were reviewed. Information collected from medical records included signalment, clinical signs, physical examination and diagnostic test results, treatment, and outcome. The Naranjo algorithm was used to estimate the probability of an adverse drug reaction for each dog. RESULTS All dogs had an acute onset of erythematous macules or generalized erythroderma. Histologic features of skin biopsy specimens had 3 patterns representing a progressive spectrum of inflammation. Most dogs had vomiting (n = 17) and hematochezia (10). Signs of gastrointestinal disease became evident before, after, or concurrent with the onset of skin lesions in 10, 3, and 5 dogs, respectively. Inflammatory bowel disease, pancreatitis, and adverse food reaction were diagnosed in 5, 3, and 3 dogs, respectively. The cause of the gastrointestinal signs was not identified for 8 dogs. Eight dogs had a Naranjo score consistent with a possible adverse drug reaction. Treatment of skin lesions included drug withdrawal (n = 15), antihistamines (16), and corticosteroids (14). Signs of gastrointestinal disease and skin lesions resolved at a mean of 4.6 days and 20.8 days, respectively, after onset. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated acute erythroderma may be associated with > 1 gastrointestinal disease or an adverse drug reaction in some dogs. Recognition of the clinical and histologic features of this syndrome is essential for accurate diagnosis. PMID- 29190197 TI - Psychometric properties of the Canine Symptom Assessment Scale, a multidimensional owner-reported questionnaire instrument for assessment of physical symptoms in dogs with solid tumors. AB - OBJECTIVE To describe development and initial psychometric testing of the Canine Symptom Assessment Scale (CSAS), a multidimensional owner-reported questionnaire instrument, in a population of dogs with solid tumors enrolled in clinical trials. DESIGN Questionnaire development and validation study. ANIMALS 238 client owned dogs with solid tumors. PROCEDURES A 14-symptom questionnaire was developed. Symptoms were defined as subjective physical disturbances dogs experienced during the course of daily living as assessed through proxy reports of pet owners. For each symptom, owners reported frequency and severity of the symptom and extent of distress caused by the symptom for the dog and the owner. Questionnaire content, symptom prevalence and dimensionality, internal consistency, and factor structure were examined. Construct and criterion validity were examined via comparison with the Canine Brief Pain Inventory (CBPI). RESULTS Symptom prevalence was high, with pain and lack of energy reported in most dogs. Severity, versus frequency, was most highly correlated with both dog and owner distress. Two symptoms were removed from consideration because of poor performance. Analysis of the remaining 12 symptoms revealed that they could be grouped into 3 factors: malaise, anxiety, and digestive upset. The CSAS factor and total scores demonstrated predictable relationships with quality of life and pain scores as measured by the CBPI, including a significant association between increasing symptom burden and decreasing quality of life. The Cronbach alpha for the CSAS was 0.77. CONCLUSIONS AND CLINICAL RELEVANCE The 12-item CSAS was a psychometrically sound owner-reported instrument for assessment of symptom frequency and characteristics in client-owned dogs with solid tumors. Potential applications include clinical research and practice settings. PMID- 29190198 TI - Pathology in Practice. PMID- 29190199 TI - ECG of the Month. PMID- 29190202 TI - Lung lobe torsion in seven juvenile dogs. AB - CASE DESCRIPTION 7 juvenile (< 12 months old) dogs with lung lobe torsion were evaluated. CLINICAL FINDINGS All patients were male; breeds included Pug (n = 5), Chinese Shar-Pei (1), and Bullmastiff (1). Dyspnea and lethargy were the most common initial complaints, with a duration of clinical signs ranging from 1 to 10 days. A CBC showed leukocytosis and neutrophilia in all dogs. Anemia was present in 6 dogs, 2 of which received packed RBC transfusions. The diagnosis was made on the basis of results of thoracic radiography, CT, ultrasonography, or a combination of modalities. The left cranial lung lobe was most commonly affected (n = 4), followed by the right middle lung lobe (2) and the right cranial lung lobe (1). TREATMENT AND OUTCOME A lateral intercostal thoracotomy with lobectomy of the affected lobe was performed in all patients. All dogs survived to be discharged between 1 and 2 days postoperatively. Six of 7 owners contacted for follow-up information 7 to 170 months after discharge reported satisfaction with the treatment and no apparent signs of recurrence of disease. CLINICAL RELEVANCE The juvenile patients of this report were successfully treated surgically with no apparent complications. Clinicians should be aware of the possibility of lung lobe torsion when evaluating young dogs with clinical signs related to the respiratory system, including those with vague signs, to avoid undue delays in treatment.

AB - Renin angiotensin system (RAS) is an endogenous hormone system involved in the control of blood pressure and fluid volume. Dysregulation of RAS has a pathological role in causing cardiovascular diseases through hypertension. Among several key components of RAS, angiotensin peptides, varying in amino acid length and biological function, have important roles in preventing or promoting hypertension, cardiovascular diseases, stroke, vascular remodeling etc. These peptides are generated by the metabolism of inactive angiotensinogen or its derived peptides by hydrolyzing action of certain enzymes. Angiotensin II, angiotensin (1-12), angiotensin A and angiotensin III bind primarily to angiotensin II type 1 receptor and cause vasoconstriction, accumulation of inflammatory markers to sub-endothelial region of blood vessels and activate smooth muscle cell proliferation. Moreover, when bound to angiotensin II type 2 receptor, angiotensin II works as cardio-protective peptide and halt pathological cell signals. Other peptides like angiotensin (1-9), angiotensin (1-7), alamandine and angiotensin IV also help in protecting from cardiovascular diseases by binding to their respective receptors.

PMID- 29190209 TI - National Study of Burnout and Career Satisfaction Among Physician Assistants in Oncology: Implications for Team-Based Care. AB - PURPOSE: A high rate of burnout has been reported in oncology physicians. Physician assistants (PAs) may also face similar risks of burnout. We sought to measure the personal and professional characteristics associated with burnout and career satisfaction and the potential impact on the oncology PA workforce. PARTICIPANTS AND METHODS: A national survey of PAs in oncology was completed by using the Maslach Burnout Inventory from September 2015 to January 2016. RESULTS: In all, 855 PAs were contacted and 250 submitted complete surveys (response rate, 29.2%). Respondents were representative of PAs in oncology with a mean age of 41.8 years, females (88.8%), academic practice (55.2%), urban location (61.2%), outpatient (74.4%), medical oncology (75.2%), worked 41 to 50 hours per week (52.8%), and had a mean of 9.6 years as a PA in oncology. Burnout was reported in 34.8% of PAs, 30.4% reported high emotional exhaustion, 17.6% reported high depersonalization, and 19.6% reported a low sense of personal accomplishment. In multivariable analysis, age, time spent on indirect patient care, oncology subspecialty, and relationship with collaborating physician were factors associated with burnout. Career and specialty satisfaction was high (86.4% and 88.8%, respectively). In the next 2 years, only 3.6% of PAs plan to pursue a different career or specialty and only 2.0% plan to retire. CONCLUSION: Despite high career and specialty satisfaction, burnout is reported in one third of PAs in oncology. Further exploration of the relationship between PAs and collaborating physicians may provide insight on methods to decrease burnout. Negligible short-term attrition of the current oncology PA workforce is anticipated. PMID- 29190210 TI - Ceftriaxone-Resistant Neisseria gonorrhoeae, Canada, 2017.

AB - Aim The aim of this study is to review the legal implications, the technology, the indications and the management of women with a familial background of breast and/or ovarian cancer. Methods We have reviewed the literature and national Austrian guidelines to describe the uptake of genetic counseling and the management options offered in Austria. Results Genetic testing for the BRCA1 and 2 mutations is free and readily available through a nation-wide program. Increased awareness and the availability of screening programs and prophylactic surgery have resulted in a profound increase in genetic counseling and testing in women with a familial background of breast and ovarian cancer in Austria. Conclusion While readily available country-wide counseling has led to an increase in counseling and testing, Austrian legislation mandates "non-directional counseling" resulting in a comparatively low uptake of prophylactic surgery. PMID- 29190212 TI - Knowledge, attitude and practice towards eating and physical activity among primary school children in Brunei: a cross-sectional study. AB - Background Childhood obesity has become a global public health crisis. Many studies have been conducted to explore the knowledge, attitude and practices towards eating and physical activity amongst parents and healthcare workers. However, very little is known amongst children. It is imperative to understand these factors as they have been associated with obesity among children. Objective This study aimed to assess the knowledge, attitude and practices of Bruneian children towards eating and physical activity, in order to identify the factors that influence the development of obesity. Methods The study involved 353 children from four primary schools in Brunei. The data collection tool used was modified validated questionnaires with sections on demographic characteristic, knowledge about obesity, eating habits and physical activity. Results The majority of children (>60%) had good knowledge of obesity and intake of healthy food, but, 84.2% lacked knowledge on the required daily servings of fruits and vegetables. 68.8% purchased food and beverages from their school canteen. 93.8% were aware about the health benefits of physical activity and 70.2% spent only 1 2 h of screen time per day, however, 46.9% did not meet the recommended amount of physical activity although they reported to have performed enough. This suggested that a comprehensive education on food intake requirements and physical activity are necessary in order to better educate children. Conclusion Health educators and public health professionals may find our findings useful in order to plan and develop tailored interventions for children, as well as better promotion of a healthy lifestyle to children and their families. PMID- 29190213 TI - The Transition from Military Nurse to Nurse Faculty: A Descriptive Study. AB - Aim The aim of this qualitative descriptive study was to describe the transition from military nurse to nurse faculty. Background There is a global shortage of qualified nurse faculty. Recruitment of retiring or separating military nurses is a viable solution. Methods Content and thematic analysis of semi-structured interviews of former military nurses (N=13) was undertaken. Results The transition from military nurse to nurse faculty includes acknowledgment of the reality of academic culture, appreciation of the journey to bridge the gap, and culmination of a new identity. Leadership skills acquired during military service proved instrumental to a successful transition. Conclusions Recognizing this transition and the strengths these nurses offer provides evidence for focused orientation programs to increase recruitment and retention of these faculty.

PMID- 29190216 TI - Networked concave microwell arrays for constructing 3D cell spheroids. AB - The engineered three-dimensional (3D) cell cultivation system for the production of multicellular spheroids has attracted considerable attention due to its improved in vivo relevance to cellular communications compared with the traditional two-dimensional (2D) cell culture platform. The formation and maintenance of cell spheroids in a healthy condition is the critical factor for tissue engineering applications such as the repair of damaged tissues, the development of organ replacement parts and preclinical drug tests. However, culturing spheroids in conventional isolated single wells shows limited yield and reduced maintenance periods due to the lack of proper supplies of nutrition as well as intercellular chemical signaling. Here, we develop novel networked concave microwell arrays for the effective construction of 3D multi-cellular spheroids. The proposed method provides a suitable structure for the diffusion of oxygen, water-soluble nutrients and cytokines for cell-cell interactions between the spheroids in neighboring microwells. We have further demonstrated that hepatocyte spheroid cultured networked concave microwells show enhanced cell viability and albumin secretion compared to the un-networked control group over two weeks. Our results reveal that multi-cellular functionality can be tuned up by networking individual 3D spheroids without supplying additional chemicals or biological supplements. We anticipate our result to be useful in high-throughput cellular screening platforms to study cell-cell interactions, in response to diverse chemical stimuli as well as the development of the in vivo mimicking of the customized 3D tissue culture system. PMID- 29190217 TI - The Role of Histopathology and Immunohistochemistry in the Diagnosis of Cutaneous Leishmaniasis Without "Discernible" Leishman-Donovan Bodies. AB - BACKGROUND: Histopathology plays an important role in the diagnosis of cutaneous leishmaniasis (CL) but Leishman-Donovan (LD) bodies may not always be discernible. Recently, anti-CD1a antibody (Ab), clone MTB1, was found to decorate LD bodies immunohistochemically. OBJECTIVE: Can histopathology without discernible LD bodies be used to diagnose CL, and can immunohistochemistry using anti-CD1a Ab, clone MTB1, detect LD bodies in these cases. METHODS: Suspected CL lesions were studied histopathologically and immunohistochemically, and the patients' clinical files were reviewed. RESULTS: Of the 196 patients with suspected CL, direct smear demonstrated LD bodies in 50 (25.5%). Of the remaining 146 patients, 118 underwent biopsy. In 56 (47.5%) patients, the hematoxylin-eosin stained sections revealed LD bodies. In 47 (39.8%) patients, LD bodies were not discerned but the histopathology demonstrated histiocytic infiltrates with varying numbers of plasma cells along with other inflammatory cells, and negative Ziehl-Neelsen and periodic acid-Schiff stains. This pattern was termed "histopathology consistent with leishmaniasis." The history, clinical findings, and response to anti-leishmania therapy supported the diagnosis of CL in all of them, and immunostains for CD1a, clone MTB1, detected LD bodies in 11 (23.4%) of these 47 patients. CONCLUSIONS: "Histopathology consistent with CL" along with appropriate clinical findings supports the diagnosis of CL in an endemic area, and immunostains with CD1a Ab, clone MTB1, may help in the minority of the cases. PMID- 29190218 TI - Validation of a Real-Time Minute-to-Minute Urine Output Monitor and the Feasibility of Its Clinical Use for Patients Undergoing Cardiac Surgery. AB - Acute kidney injury after cardiac surgery is associated with increased morbidity and mortality. Methods for measuring urine output in real time may better ensure renal perfusion perioperatively in contrast to the current standard of care where urine output is visually estimated after empiric epochs of time. In this study, we describe an accurate method for monitoring urine output continuously during cardiopulmonary bypass. This may provide a means for setting patient-specific targets for blood pressure and cardiopulmonary bypass flow as a potential strategy to reduce the risk for acute kidney injury.

AB - OBJECTIVES: The aim of this study was to assess the potential of noncontrast magnetic resonance imaging (NC-MRI) with diffusion-weighted imaging (DWI) in characterization of breast lesions in comparison to dynamic contrast-enhanced MRI (DCE-MRI) at 3 T. MATERIALS AND METHODS: Consecutive patients with conventional imaging (mammography, ultrasound) BI-RADS 4/5 findings were included in this institutional review board-approved single-center study. All underwent 3 T breast MRI including readout-segmented DWI, DCE, and T2-weighted sequences. Final diagnosis was defined by histopathology or follow-up (>24 months). Two experienced radiologists (R1, R2) independently assigned lesion conspicuity (0 = minimal to 3 = excellent) and BI-RADS scores to NC-MRI (readout-segmented DWI including apparent diffusion coefficient maps) and DCE-MRI (DCE and T2-weighted). Receiver operating characteristics, kappa statistics, and visual grading characteristics analysis were applied. RESULTS: Sixty-seven malignant and 56 benign lesions were identified in 113 patients (mean age, 54 +/- 14 years). Areas under the receiver operating characteristics curves were similar: DCE-MRI: 0.901 (R1), 0.905 (R2); NC-MRI: 0.882 (R1), 0.854 (R2); P > 0.05, respectively. The kappa agreement was 0.968 (DCE-MRI) and 0.893 (NC-MRI). Visual grading characteristics analysis revealed superior lesion conspicuity by DCE-MRI (0.661, P < 0.001). CONCLUSIONS: Diagnostic performance and interreader agreement of both NC-MRI and DCE-MRI is high, indicating a potential use of NC-MRI as an alternative to DCE-MRI. However, inferior lesion conspicuity and lower interreader agreement of NC-MRI need to be considered. PMID- 29190228 TI - Hepatic Venous Outflow Stenosis After Auxiliary Left Hemiliver Transplantation Diagnosed by Ultrasonic Shear Wave Elastography Combined With Doppler Ultrasonography. AB - Hepatic vein stenosis after liver transplantation is a relatively rare complication that could even result in graft loss. However, it is difficult to arrive at a definite diagnosis at the early stage of postoperation, and there are few researches on ultrasonic shear wave elastography in the diagnosis of hepatic vein stenosis. We report the case of an 11-year-old male patient with cirrhosis due to hepatolenticular degeneration who received an auxiliary left hemiliver graft from his uncle. Massive ascites developed in 4 days after the operation. Stenosis was suspected at the site of anastomosis by Doppler ultrasonography when elevating the velocity of the left hepatic vein. Meanwhile, increased stiffness of the graft was revealed by ultrasonic shear wave elastography. The stenosis was confirmed by subsequent digital subtraction angiography. Ascites decreased gradually after the stent implantation. Our case indicates that ultrasonic shear wave elastography combined with Doppler ultrasonography is a promising method for noninvasive diagnosis of hepatic venous outflow stenosis following liver transplantation. PMID- 29190229 TI - CORRELATION BETWEEN OUTER RETINAL THICKENING AND RETINAL FUNCTION IMPAIRMENT IN PATIENTS WITH IDIOPATHIC EPIRETINAL MEMBRANES. AB - PURPOSE: To examine the relationship between retinal layer thickness, retinal sensitivity, and visual function in patients with idiopathic epiretinal membrane using spectral domain optical coherence tomography automated segmentation algorithm. METHODS: Twenty-four eyes with epiretinal membrane and 12 control eyes were enrolled. Ophthalmic evaluations included best-corrected visual acuity, mean retinal sensitivity (MRS) of radial 10 degrees and 4 degrees areas tested with microperimetry, and measurements of 4 retinal layer thicknesses by means spectral domain optical coherence tomography. Relations between retinal layer thickness, MRS, and best-corrected visual acuity values were explored. RESULTS: Compared with controls, MRS (P < 0.001) and best-corrected visual acuity (P < 0.001) values were reduced. In the epiretinal membrane group, MRS of the central 4 degrees values was associated with thickening of the outer nuclear layer (P < 0.05). Furthermore, a correlation was found between the inner nuclear layer thickening and the MRS of the central 4 degrees limited to the inferior quadrant (P < 0.05). The decreased best-corrected visual acuity values were correlated with the thickening of three of four quadrant of the inner nuclear layer, inferior and temporal quadrants of the outer plexiform layer, and finally outer nuclear layer nasal quadrant. CONCLUSION: We found a meaningful correlation between MRS impairment of the central 4 degrees and outer nuclear layer thickness and showed which intraretinal layers mainly contributes to visual acuity loss.

PMID- 29190231 TI - OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY OF THE FOVEAL AVASCULAR ZONE IN CHILDREN WITH A HISTORY OF TREATMENT-REQUIRING RETINOPATHY OF PREMATURITY. AB - PURPOSE: To examine the characteristics of the foveal vascular structure of patients with retinopathy of prematurity (ROP) by optical coherence tomography angiography. METHODS: Ten patients with a history of laser photocoagulation or cryopexy treatment for Stage 3 (Zone >= II) ROP and 10 normal subjects (controls) were included. Foveal avascular zone, vessel density, vessel length, and vascular diameter index were measured by optical coherence tomography angiography using the 3 * 3-mm Early Treatment Diabetic Retinopathy Study (ETDRS) sectors. RESULTS: The median foveal avascular zone values of the patients with ROP and controls were 0.103 mm and 0.260 mm, respectively (P = 0.0025). The medians of the vessel density, vessel length, and vascular diameter index of the patients with ROP were 0.218 mm/mm, 11.75 mm/mm, and 18.00 MUm, respectively, in ETDRS Sector 1 and did not significantly differ from those of the controls (P = 0.940, 0.733, and 0.705, respectively). For the average of ETDRS Sectors 2 to 5, the medians of the vessel density, vessel length, and vascular diameter index for the patients with ROP were 0.347 mm/mm, 18.95 mm/mm, and 18.28 MUm, respectively; vessel density and vessel length were significantly smaller than those of the controls (P = 0.002 and 0.003, respectively), but there was no significant difference in vascular diameter index (P = 0.286). CONCLUSION: Optical coherence tomography angiography guided foveal avascular zone was significantly smaller in patients with ROP than in controls. Our results indicate that foveal vascular development may be altered in patients with a history of treatment-requiring ROP. PMID- 29190232 TI - MACULAR ATROPHY FINDINGS BY OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY COMPARED WITH FUNDUS AUTOFLUORESCENCE IN TREATED EXUDATIVE AGE-RELATED MACULAR DEGENERATION. AB - PURPOSE: To compare the areas of choriocapillaris (CC) nonperfusion and macular atrophy (MA) in treated exudative age-related macular degeneration. METHODS: This was a prospective, observational, cross-sectional study. Forty-four eyes exhibiting MA (42 patients with age-related macular degeneration), with a dry macula, underwent fundus autofluorescence and optical coherence tomography angiography. The area of MA detected by fundus autofluorescence and CC nonperfusion detected by optical coherence tomography angiography was measured using image analysis software. The rates of concordance between the MA and CC nonperfusion areas were calculated. We qualitatively and quantitatively compared the areas of MA and CC nonperfusion in age-related macular degeneration eyes. RESULTS: The mean areas of MA and CC nonperfusion were 5.95 +/- 4.50 mm and 10.66 +/- 7.05 mm, respectively (paired t-test, P < 0.001). In 39 eyes (88.6%), the CC nonperfusion area was larger than the MA area, and the mean CC nonperfusion area was significantly larger than the mean MA area. Fundus autofluorescence matching optical coherence tomography angiography showed that the CC nonperfusion area was almost included in the MA area. The mean concordance rate for the MA area inside the CC nonperfusion area was 87.7 +/- 13.9%. CONCLUSION: The MA and CC nonperfusion areas markedly overlapped. The area of CC nonperfusion correlated with the MA area. Choroidal ischemia might be involved in the pathogenesis of MA in treated age-related macular degeneration.This is an open access article distributed under the Creative Commons Attribution License 4.0 (CCBY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. PMID- 29190233 TI - Correspondence. PMID- 29190234 TI - FAMILIAL CENTRAL SEROUS CHORIORETINOPATHY. AB - PURPOSE: To assess ophthalmologic characteristics in patients and unaffected individuals in families with multiple members affected by central serous chorioretinopathy (CSC), both at presentation and long-term follow-up. METHODS: In 103 subjects from 23 families with at least 2 affected patients with CSC per family, prospective extensive ophthalmologic examination was performed, including best-corrected visual acuity, indirect ophthalmoscopy, digital color fundus photography, optical coherence tomography, fundus autofluorescence, and fluorescein angiography imaging. From these, 24 individuals from 6 families had undergone extensive ophthalmologic examination in either 1994 or 1995 and were followed up in this study. RESULTS: Subretinal fluid accumulation on optical coherence tomography and/or "hot spots" of leakage on fluorescein angiography indicative of CSC were detected in 45 of 103 phenotyped subjects (44%). Findings suggestive of CSC, but without the presence of subretinal fluid on optical coherence tomography and/or "hot spots" of leakage on fluorescein angiography, were observed in an additional 27 family members (26%). In 4 of 17 previously nonaffected subjects (24%) from the 24 individuals that were followed up after more than 20 years, we found more severe abnormalities. CONCLUSION: Extensive ophthalmologic phenotyping resulted in the detection of (suggestive) CSC in 52% of family members of patients with CSC. Genetic factors may play an important role in these specific CSC cases. Moreover, during follow-up, progressive disease can occur in a noteworthy number of patients.

PMID- 29190236 TI - APOPTOSIS AND ANGIOFIBROSIS IN DIABETIC TRACTIONAL MEMBRANES AFTER VASCULAR ENDOTHELIAL GROWTH FACTOR INHIBITION: Results of a Prospective Trial. Report No. 2. AB - PURPOSE: We sought to characterize the angiofibrotic and apoptotic effects of vascular endothelial growth factor (VEGF)-inhibition on fibrovascular epiretinal membranes in eyes with traction retinal detachment because of proliferative diabetic retinopathy. METHODS: Membranes were excised from 20 eyes of 19 patients (10 randomized to intravitreal bevacizumab, 10 controls) at vitrectomy. Membranes were stained with antibodies targeting connective tissue growth factor (CTGF) or VEGF and colabeled with antibodies directed against endothelial cells (CD31), myofibroblasts, or retinal pigment epithelium markers. Quantitative and colocalization analyses of antibody labeling were obtained through immunofluorescence confocal microscopy. Masson trichrome staining, cell counting of hematoxylin and eosin sections, and terminal dUTP nick-end labeling staining were performed. RESULTS: High levels of fibrosis were observed in both groups. Cell apoptosis was higher (P = 0.05) in bevacizumab-treated membranes compared with controls. The bevacizumab group had a nonsignificant reduction in colocalization in CD31-CTGF and cytokeratin-VEGF studies compared with controls. Vascular endothelial growth factor in extracted membranes was positively correlated with vitreous levels of VEGF; CTGF in extracted membranes was negatively correlated with vitreous levels of CTGF. CONCLUSION: Bevacizumab suppresses vitreous VEGF levels, but does not significantly alter VEGF or CTGF in diabetic membranes that may be explained by high baseline levels of fibrosis. Bevacizumab may cause apoptosis within fibrovascular membranes. PMID- 29190237 TI - IMPACT OF ETIOLOGY ON THE OUTCOME OF PEDIATRIC RHEGMATOGENOUS RETINAL DETACHMENT. AB - PURPOSE: To evaluate the clinical features and surgical outcomes of rhegmatogenous retinal detachment in pediatric patients and to identify the independent effect of each etiology on the outcome. METHODS: A review of patients younger than 18 years who underwent vitreoretinal surgery was conducted at Chang Gung Memorial Hospital, Taoyuan, between 2008 and 2013. Patients were classified according to etiology. Multivariate logistic regression analysis was performed to evaluate the association between outcomes and each etiologic factor. RESULTS: A total of 86 cases (mean age: 12.9 +/- 4.8 years; 76.7% male) were included. The mean follow-up was 46.3 +/- 23.9 months. In 90.7% of patients, at least one etiology could be identified, including myopia (55.8%), congenital or developmental disease (39.5%), trauma (27.9%), and previous intraocular surgery (17.4%). Among the risk factors examined in this study, congenital or developmental disease had the worst functional outcomes (P = 0.006). Myopia was a good prognostic factor for a better retinal reattachment rate (P = 0.030). Myopic rhegmatogenous retinal detachment had the lowest probability of surgical failure (8.08%), and idiopathic rhegmatogenous retinal detachment had the lowest likelihood of postoperative visual decline (4.65%). CONCLUSION: Myopia and congenital or developmental disease are the leading etiologies of pediatric rhegmatogenous retinal detachment. Different etiologies are associated with distinctive outcomes, and congenital and developmental diseases are independent prognostic factors of a poor response.

PMID- 29190238 TI - LONGITUDINAL CHANGES IN THE OPTIC NERVE HEAD AND RETINA OVER TIME IN VERY YOUNG CHILDREN WITH FAMILIAL EXUDATIVE VITREORETINOPATHY. AB - PURPOSE: To explore vitreoretinal pathologies and their longitudinal changes visible on handheld optical coherence tomography (OCT) of young children with familial exudative vitreoretinopathy. METHODS: The authors retrospectively analyzed handheld OCT images for vitreoretinal interface and retinal abnormalities and optic nerve head (ONH) elevation. RESULTS: From 26 eyes of 16 children (mean age 32 months) with familial exudative vitreoretinopathy, 10 had ONH dragging on photographs, and in these, handheld OCT revealed temporal and anterior retinal displacement, prominent vitreopapillary adhesion or traction, and retinal nerve fiber layer thickening at ONH margins with adjacent retinal elevation. Despite a nearly normal photographic appearance, handheld OCT revealed ONH elevation with vitreopapillary traction (6/16 eyes), ONH edema (1/16 eye), and retinal vascular protrusion (5/16 eyes). Handheld OCT-visualized vitreous abnormalities (18/26 eyes) were more prevalent at higher stages of disease. Handheld OCT-visualized elevation of ONH and the retina worsened over time in nine eyes and improved in 5/6 eyes after vitrectomy. CONCLUSION: Handheld OCT can detect early ONH, retinal, and vitreous changes in eyes with familial exudative vitreoretinopathy. Contraction of strongly adherent vitreous in young patients with familial exudative vitreoretinopathy appears to cause characteristic ONH dragging and tractional complications without partial posterior vitreous detachment. Vitreopapillary dragging may be visible only on OCT and may progress in the absence of obvious retinal change on conventional examination. PMID- 29190240 TI - COMPARING MICROPERIMETRIC AND STRUCTURAL FINDINGS IN PATIENTS WITH BRANCH RETINAL VEIN OCCLUSION AND DIABETIC MACULAR EDEMA. AB - PURPOSE: To compare retinal sensitivity and central retinal thickness in patients with focal diabetic macular edema (DME) and edema secondary to branch retinal vein occlusion (BRVO). METHODS: In this consecutive, cross-sectional, observational study, patients with either DME or BRVO underwent measurements for best-corrected visual acuity, microperimetry, and spectral domain optical coherence tomography. Retinal thickness and sensitivity were measured using Optos Spectral optical coherence tomography/scanning laser ophthalmoscopy (Optos plc, Dunfermline, Scotland, United Kingdom). Areas defined as abnormal demonstrated edema with clearly defined cystic spaces. Abnormal and control areas were compared in mean retinal sensitivity and mean retinal thickness for both conditions. RESULTS: Twenty eyes with focal DME and nine eyes with BRVO were included. In DME, mean retinal thickness was 413.6 +/- 84.5 MUm and 291.7 +/- 36.7 MUm in abnormal and control areas, respectively. Mean retinal sensitivity was 10.22 +/- 4.23 dB and 12.25 +/- 3.57 dB, respectively. In BRVO, mean retinal thickness was 491.4 +/- 102.9 MUm and 315.9 +/- 29.9 MUm in abnormal and control areas, respectively. Mean retinal sensitivity was 6.36 +/- 5.47 dB and 13.05 +/- 2.28 dB. In DME, a decrease in retinal thickness of 0.341 MUm correlated with 1 dB reduction of retinal sensitivity, although this was not statistically significant (P = 0.717). In BRVO, however, an increase in retinal thickness of 9.702 MUm correlated with 1 dB reduction of retinal sensitivity (P = 0.001). CONCLUSION: In BRVO, an increase in retinal thickness corresponded with a significant reduction in retinal sensitivity; in DME, however, there was no significant correlation between retinal thickness and retinal sensitivity. Further study is required to assess why this is the case. The Optos Spectral optical coherence tomography/scanning laser ophthalmoscopy allows for a reliable point-to-point correlation, as microperimetry and spectral domain optical coherence tomography can be performed in the same device. PMID- 29190241 TI - AFLIBERCEPT AFTER RANIBIZUMAB INTRAVITREAL INJECTIONS IN EXUDATIVE AGE-RELATED MACULAR DEGENERATION: The ARI2 Study. AB - PURPOSE: To analyze the efficacy of aflibercept switch treatment for regression of pigment epithelial detachment (PED) in patients previously treated with ranibizumab. METHODS: Multicenter, prospective, nonrandomized clinical trial. One eye of patients presenting neovascular age-related macular degeneration with PED of more than 250 MUm in height, with persistent fluid, was included. Patients had to have received at least six ranibizumab intravitreal injections during the 12 months before enrollment. Patients were switched from ranibizumab pro re nata to aflibercept (fixed regimen, 3 monthly intravitreal injections, and then Q6). Main outcome measure was change in PED height from baseline to Week 12 after switch. Secondary outcomes were best-corrected visual acuity and PED volume changes. RESULTS: Eighty four patients were included. Mean delay between last ranibizumab intravitreal injection and switch was 44.7 days. Mean maximal PED height at baseline visit was 347 MUm (+/-109) and reduced to a mean of 266 MUm (+/-114) at Week 12 (P < 0.001) and 288.2 MUm at Week 32 (P < 0.001). Mean PED volume was reduced from 1.3 mm to 0.98 mm at Week 12 (P < 0.001). Best-corrected visual acuity improved by 3.3 Early Treatment Diabetic Retinopathy Study letters at Week 32 (P = 0.003). CONCLUSION: Aflibercept switch therapy seems to be effective on large PED in patients previously treated with pro re nata ranibizumab.

PMID- 29190243 TI - FACTORS ASSOCIATED WITH SEROUS RETINAL DETACHMENT IN HIGHLY MYOPIC EYES WITH VERTICAL OVAL-SHAPED DOME. AB - PURPOSE: This study investigated factors associated with persistent serous retinal detachment in highly myopic eyes with vertical oval-shaped domes. METHODS: Twenty-eight highly myopic patients (40 eyes) with smooth macular elevations related to a vertical oval-shaped dome were recruited. Serous retinal detachment was investigated; 11 eyes had persistent submacular fluid (study group) and 29 eyes lacked submacular fluid (control group). All patients underwent complete ophthalmologic examinations, including axial-length measurement and fluorescein angiography. Spectral domain optical coherence tomography scans through the fovea measured choroidal thicknesses, macular bulge height, and vitreoretinal interface factors. RESULTS: No studied variables (age, sex, spherical equivalence, axial length, vitreomacular traction, epiretinal membrane, and internal limiting membrane detachment) except higher macular bulge height (P = 0.03) and a reduced macular choroidal thickness (P = 0.02) were associated with the risk of serous retinal detachment. No statistically significant differences in best-corrected visual acuity were observed between the study and control groups. Serous retinal detachment always occurred at the top of the inward incurvation of the macula and was characterized by multiple hyperfluorescent granular patches on fluorescein angiography. CONCLUSION: A higher macular bulge height and a reduced macular choroidal thickness might be important factors in the development of serous retinal detachment in patients with vertical oval-shaped domes. PMID- 29190244 TI - EVALUATION OF OBSTRUCTIVE SLEEP APNEA SYNDROME AS A RISK FACTOR FOR DIABETIC MACULAR EDEMA IN PATIENTS WITH TYPE II DIABETES. AB - PURPOSE: To evaluate the association between obstructive sleep apnea and diabetic macular edema (DME) in patients with Type II diabetes, using the apnea-hypopnea index and other nocturnal hypoxemia parameters. METHODS: This cross-sectional, case-control study included 99 patients with Type II diabetes: the first group included patients with DME (DME+ group) and the second patients without DME (DME- group). Polysomnography was performed in all patients. The two groups were compared, and the risk factors were studied using logistic regression. RESULTS: The DME+ group comprised 38 patients, and the DME- group comprised 61 patients, aged a mean 68.8 years and 66.3 years (P = 0.27), respectively; mean body mass index was 29.7 and 30.9 (P = 0.16), respectively. The mean apnea-hypopnea index was significantly higher in the DME+ group (43.95 [13.5-87.3]) than in the DME- group (35.18 [3.55-90.7]) (P = 0.034). Patients with DME had more severe obstructive sleep apnea (apnea-hypopnea index >30) than the others: 71% versus 50.8% (P = 0.049). Cumulative time of SPO2 below 90% (CT90%) was independently associated with DME after adjusting for confounding factors, whereas there was no difference between the oxygen desaturation index and minimum O2 saturation. CONCLUSION: Severe obstructive sleep apnea (apnea-hypopnea index >30) and parameters of nocturnal hypoxemia (cumulative time of SPO2 below 90%) are associated with DME. PMID- 29190245 TI - CHARACTERIZATION AND CORRELATION OF "JAMPOL DOTS" ON ADAPTIVE OPTICS WITH FOVEAL GRANULARITY ON CONVENTIONAL FUNDUS IMAGING. AB - PURPOSE: To describe features characteristic of multiple evanescent white dot syndrome (MEWDS) using adaptive optics scanning laser ophthalmoscopy (AOSLO). METHODS: Six women (seven eyes) who presented with MEWDS between June 2014 and April 2017 underwent ophthalmologic examinations and multimodal imaging including infrared, AOSLO, and spectral domain optical coherence tomography. RESULTS: Bright hyperreflective lesions on AOSLO throughout the course of MEWDS could be correlated to the hyperreflective dots of foveal granularity on infrared imaging without apparent corresponding changes on spectral domain optical coherence tomography. During the acute phase of MEWDS, extrafoveal hyperreflective dots were also visible on AOSLO and infrared and were associated with accumulations of hyperreflective material above the retinal pigment epithelium on spectral domain optical coherence tomography. CONCLUSION: Foveal granularity on conventional fundus imaging could be correlated with hyperreflective lesions visible on AOSLO. We hypothesize that these hyperreflective lesions, "Jampol dots," are the foveal corollaries of the same process associated with the classic "dot" lesions in MEWDS. Based on the intact photoreceptor mosaic on AOSLO, we surmise that this material is accumulating at the level of the retinal pigment epithelium. PMID- 29190246 TI - OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY FINDINGS OF DEEP CAPILLARY PLEXUS MICROISCHEMIA AFTER INTRAVENOUS CHEMOTHERAPY FOR RETINOBLASTOMA. AB - PURPOSE: To study changes in the foveal microvascular anatomy using optical coherence tomography angiography (OCTA) after intravenous chemotherapy (IVC) for retinoblastoma (RB). METHODS: A retrospective comparative case-control series included 10 age-matched normal eyes with no documented ocular pathology (control), 10 fellow eyes of patients with unilateral RB treated with IVC (RB fellow), and 10 eyes with extramacular RB in patients with bilateral RB treated with IVC (RB tumor). All eyes were scanned using enhanced depth imaging optical coherence tomography and OCTA. Enhanced depth imaging optical coherence tomography measurements of central macular thickness and subfoveolar choroidal thickness as well as OCTA measurements of foveal avascular zone (FAZ) area in superficial (sFAZ) and deep (dFAZ) plexus and capillary density (CD) in the superficial (sCD) and deep (dCD) plexus were performed. Comparison among the three groups was conducted. RESULTS: Among the three cohorts (control, RB fellow, and RB tumor), there was no difference in mean age at measurement (12, 10, and 12 years) and mean interval between last IVC and OCTA (RB fellow and RB tumor) (9, 10 years). Optical coherence tomography and OCTA revealed no significant difference in central macular thickness (all P >= 0.161), choroidal thickness (all P >= 0.066), sFAZ (all P >= 0.618), dFAZ (all P >= 0.610), and sCD (all P >= 0.638) comparing controls versus RB fellow, controls versus RB tumor, and RB fellow versus RB tumor. By contrast, mean dCD was significantly greater in controls (52%), compared with both RB fellow (49%, P = 0.026) and RB tumor (48%, P = 0.028) groups, but no difference was found between RB fellow and RB tumor (49% vs. 48%, P = 0.515). LogMAR visual acuity showed no difference among the three groups (all P >= 0.150). CONCLUSION: At mean 10-year follow-up, slight reduction in dCD seems to occur after IVC for RB without alterations in central macular thickness, choroidal thickness, FAZ, or sCD and without visual compromise. PMID- 29190247 TI - EFFICACY OF DOUBLE DOSE PHOTODYNAMIC THERAPY FOR CIRCUMSCRIBED CHOROIDAL HEMANGIOMA. AB - PURPOSE: To evaluate the efficacy of photodynamic therapy using a double dose of verteporfin for patients with circumscribed choroidal hemangioma. METHODS: This retrospective comparative case series evaluated data from 10 patients who were treated using double dose photodynamic therapy (12 mg/m) and seven patients who were treated using the standard dose (6 mg/m). A laser was applied with a radiant exposure of 50 J/cm. The ophthalmologic examinations were performed at baseline and 1 year after the treatment and included best-corrected visual acuity, slit lamp biomicroscopy, fundus examination, spectral domain optical coherence tomography, and B-scan ultrasonography. RESULTS: The mean age in the double dose group was 51.60 years, compared with 50.57 years in the standard-dose group. The only significant difference between the two groups' baseline characteristics was observed in their initial tumor heights. Foveal center thickness, subretinal fluid, and subfoveal choroidal thickness decreased significantly at 1 year after treatment in both groups. Tumor height and the greatest linear dimension of the tumor's base only decreased significantly in the double dose group (P = 0.031). Both groups did not experience significant visual improvements. CONCLUSION: Double dose photodynamic therapy was effective and safe for treating circumscribed choroidal hemangioma and provided better tumor regression with similar resorption of subretinal fluid, compared with standard-dose photodynamic therapy. PMID- 29190248 TI - COMBINING EXTERNAL NEEDLE DRAINAGE AND SCLERAL BUCKLING WITH VITRECTOMY FOR THE REPAIR OF BULLOUS RETINAL DETACHMENTS. AB - PURPOSE: To describe a technique of combined scleral buckle with external needle drainage and vitrectomy in the treatment of bullous exudative retinal detachment, schisis detachment, or bullous retinoschisis threatening the fovea. METHODS: A retrospective chart review of four eyes of four patients who underwent the procedure described. RESULTS: Four eyes of four patients who underwent combined scleral buckling with external needle drainage and vitrectomy by a single surgeon for a bullous exudative retinal detachment, schisis detachment, or bullous retinoschisis threatening the fovea were included in this series. All four patients were attached after a single surgical intervention. No patient developed complications from the external drainage. CONCLUSION: External needle drainage of bullous subretinal or intraschisis fluid in combination with vitrectomy is a successful technique for treating bullous exudative retinal detachments, schisis detachment, or foveal-threatening retinoschisis. The technique avoids many complications associated with conventional drainage procedures. Long-term results seem promising because of extended follow-up demonstrating sustained anatomical success with a single intervention. PMID- 29190249 TI - COMPARISON OF 3 MM * 3 MM VERSUS 6 MM * 6 MM OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY SCAN SIZES IN THE EVALUATION OF NON-PROLIFERATIVE DIABETIC RETINOPATHY. AB - PURPOSE: To evaluate the utility of different optical coherence tomography angiography scan protocols in evaluating retinal changes in non-proliferative diabetic retinopathy. METHODS: Patients were imaged with the RTVue XR Avanti OCT 3 mm * 3 mm and 6 mm * 6 mm "Angio Retina" scan protocols. Ability to clearly delineate the foveal avascular zone (FAZ), FAZ remodeling, microaneurysms, capillary nonperfusion, motion, and doubling artifacts were evaluated. RESULTS: Forty-six eyes from 27 patients were enrolled. Eighty-nine percent of 3 mm * 3 mm versus 59% of 6 mm * 6 mm scans clearly delineated the FAZ (P = 0.001). Eighty percent of 3 mm * 3 mm versus 43% of 6 mm * 6 mm scans demonstrated FAZ remodeling (P = 0.0002). Microaneurysms were detected by 57% of 6 mm * 6 mm and 35% of 3 mm * 3 mm scans (P = 0.003). Capillary nonperfusion was detected in 87% of 3 mm * 3 mm scans versus 89% of 6 mm * 6 mm scans (P = 0.99). No significant differences were noted in the incidence of artifacts between the scan sizes (motion artifact P = 0.29 and doubling artifact P = 0.29). CONCLUSION: 3 mm * 3 mm scan delineated FAZ and remodeling better than 6 mm * 6 mm scan, likely because of its higher scan density. 6 mm * 6 mm scans detected microaneurysms more readily than 3 mm * 3 mm, likely because of its larger scan area. There were utility for both 3 mm * 3 mm and 6 mm * 6 mm scans when evaluating these patients. PMID- 29190250 TI - CELLULAR IMAGING OF THE TAPETAL-LIKE REFLEX IN CARRIERS OF RPGR-ASSOCIATED RETINOPATHY. AB - PURPOSE: To examine the features of the tapetal-like reflex (TLR) in female carriers of RPGR-associated retinopathy by means of adaptive optics scanning light ophthalmoscopy (AOSLO) and spectral domain optical coherence tomography. METHODS: Nine molecularly confirmed RPGR carriers and three healthy controls underwent ocular examination and the following retinal imaging modalities: color photography, near-infrared reflectance, fundus autofluorescence, spectral domain optical coherence tomography, and AOSLO. After identifying TLR areas across all imaging modalities, normalized local contrast of outer retinal bands on spectral domain optical coherence tomography was calculated and AOSLO-acquired photoreceptor mosaic analysis was performed. RESULTS: Seven carriers had TLR areas, which colocalized with increased rod photoreceptor reflectivity on confocal AOSLO and reduced cone photoreceptor densities. Parafoveal TLR areas also exhibited reduced local contrast (i.e., increased reflectivity) of the outer retinal bands on spectral domain optical coherence tomography (inner segment ellipsoid zone and outer segment interdigitation zone). Healthy controls did not show TLR. CONCLUSION: The cellular resolution provided by AOSLO affords the characterization of the photoreceptor mosaic in RPGR carriers with a TLR. Features revealed include reduced cone densities, increased cone inner segment diameters, and increased rod outer segment reflectivity.This is an open access article distributed under the Creative Commons Attribution License 4.0 (CCBY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

PMID- 29190252 TI - AIR/FLUID-DROPPING TECHNIQUE FOR INTRACAPSULAR DISTILLED WATER APPLICATION: A Vitrectomy Approach for Selective Targeting of Lens Epithelial Cells. AB - PURPOSE: We describe a simplified technique of intracapsular distilled water application for targeting lens epithelial cells using vitrectomy approach of fluid-air exchange and to evaluate the reliability and safety of this technique. METHODS: Consecutive patients with cataract were randomly assigned to treatment group and control group. After the nucleus removal and cortical aspiration, the space of anterior chamber and capsular bag were maintained with continuous infusion of sterile air by using fluid-air exchange technique through side-port incision. Distilled water was dropped into the capsular bag using a specially designed syringe. A concave air-fluid surface (a physical phenomenon) insured the contact of distilled water with the inner surface of the capsule without overflowing from the bag. The distilled water remained in place for 3 minutes and was then removed by the syringe. RESULTS: No intraoperative surgical complication was observed, and no damage to adjacent intraocular structures was observed during the postoperative follow-up. There was no statistical difference of corneal endothelial cell loss between the treatment group and the control group. Histological study confirmed damage to the lens epithelial cells from anterior capsular specimens treated by the technique. CONCLUSION: The simplified technique using vitrectomy approach is safe and specific for targeting lens epithelial cells without associated complications. PMID- 29190253 TI - Reply. PMID- 29190255 TI - Relation of antifactor-Xa peak levels and venous thromboembolism after trauma. AB - BACKGROUND: No previous studies have established the optimal antifactor Xa (anti Xa) level to guide thromboprophylaxis (TPX) dosing with enoxaparin in trauma patients. We hypothesize that achieving 0.2-0.4 IU/mL anti-Xa will decrease venous thromboembolism (VTE) rates after trauma. METHODS: This was a retrospective review of 194 intensive care unit patients sustaining blunt or penetrating trauma from January 2015 to March 2017. All received initial enoxaparin (30 mg BID subcutaneous) and mechanical devices for TPX. Peak anti-Xa levels were drawn after each third dose. The enoxaparin dose was adjusted up to a maximum of 60 mg BID subcutaneous until a peak level of 0.2-0.4 IU/mL was achieved. Data are expressed as mean +/- SD if parametric or median (IQR) if not. RESULTS: The Greenfield Risk Assessment Profile score was 9 +/- 4, Injury Severity Score 23 +/- 14, and hospital length of stay 19 (11-38) days. The overall VTE rate was 7.2% (n = 14), with 10 deep venous thromboses (DVT) and 5 pulmonary emboli (PE). One patient had both a DVT and PE. The median time to VTE diagnosis was 14 (7-17) days. In those diagnosed with a VTE, 50.0% (n = 7) never reached 0.2-0.4 IU/mL anti-Xa and 42.8% (n = 6) were diagnosed with a VTE after achieving these levels. Prophylactic levels were achieved initially in 64 (33.0%) patients, and achieved later in 38 (19.6%) additional patients, giving an overall prophylactic rate of 52.6% (n = 102). There were no differences in VTE (6.9% vs. 7.6%, p = 0.841), DVT (3.9% vs. 6.5%, p = 0.413), or PE (3.9% vs. 1.1%, p = 0.213) rates between those who became prophylactic and those who did not. CONCLUSIONS: There was no difference in VTE incidence between those achieving anti-Xa peak levels of 0.2-0.4 IU/mL and those who did not. Furthermore, these levels were never achieved in some trauma patients despite repeated dosing over a >10-day period. LEVEL OF EVIDENCE: Therapeutic study, level IV. PMID- 29190254 TI - Fibrinolysis shutdown is associated with a fivefold increase in mortality in trauma patients lacking hypersensitivity to tissue plasminogen activator. AB - BACKGROUND: Fibrinolysis shutdown (SD) is an independent risk factor for increased mortality in trauma. High levels of plasminogen activator inhibitor-1 (PAI-1) directly binding tissue plasminogen activator (t-PA) is a proposed mechanism for SD; however, patients with low PAI-1 levels present to the hospital with a rapid TEG (r-TEG) LY30 suggestive SD. We therefore hypothesized that two distinct phenotypes of SD exist, one, which is driven by t-PA inhibition, whereas another is due to an inadequate t-PA release in response to injury. METHODS: Trauma activations from our Level I center between 2014 and 2016 with blood collected within an hour of injury were analyzed with r-TEG and a modified TEG assay to quantify fibrinolysis sensitivity using exogenous t-PA (t-TEG). Using the existing r-TEG thresholds for SD (<0.9%), physiologic (LY30 0.9-2.9%), and hyperfibrinolysis (LY30 > 2.9%) patients were stratified into phenotypes. A t-TEG LY30 greater than 95th percentile of healthy volunteers (n = 140) was classified as t-PA hypersensitive and used to subdivide phenotypes. A nested cohort had t-PA and PAI-1 activity levels measured in addition to proteomic analysis of additional fibrinolytic regulators. RESULTS: This study included 398 patients (median New Injury Severity Score, 18), t-PA-Sen was present in 27% of patients. Shutdown had the highest mortality rate (20%) followed by hyperfibinolysis (16%) and physiologic (9% p = 0.020). In the non-t-PA hypersensitive cohort, SD had a fivefold increase in mortality (15%) compared with non-SD patients (3%; p = 0.003) which remained significant after adjusting for Injury Severity Score and age (p = 0.033). Overall t-PA activity (p = 0.002), PAI-1 (p < 0.001), and t PA/PAI-1 complex levels (p = 0.006) differed between the six phenotypes, and 54% of fibrinolytic regulator proteins analyzed (n = 19) were significantly different. CONCLUSION: In conclusion, acute fibrinolysis SD is not caused by a single etiology, and is clearly associated with PAI-1 activity. The differential phenotypes require an ongoing investigation to identify the optimal resuscitation strategy for these patients. LEVEL OF EVIDENCE: Prognostic, level III. PMID- 29190256 TI - Time to aortic occlusion: It's all about access. AB - INTRODUCTION: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a less invasive method of proximal aortic occlusion compared with resuscitative thoracotomy with aortic cross-clamping (RTACC). This study compared time to aortic occlusion with REBOA and RTACC, both including and excluding time required for common femoral artery (CFA) cannulation. METHODS: This was a retrospective, single-institution review of REBOA or RTACC performed between February 2013 and January 2016. Time of skin incision to aortic cross-clamp for RTACC, time required for CFA cannulation by percutaneous and open methods, and time from guide-wire insertion to balloon inflation at Zone 1 for REBOA, were obtained from videographic recordings. RESULTS: Eighteen RTACC and 21 REBOAs were performed. Median (Q1, Q3) time from skin incision to aortic cross-clamping was 317 seconds (227, 551 seconds). Median (Q1, Q3) time from start of arterial access to Zone 1 balloon occlusion was 474 seconds (431, 572 seconds) (vs. RTACC, p = 0.01). All REBOA procedures were performed with the same device. The median time to complete CFA cannulation was 247 seconds (range, 164-343 seconds), with no difference between percutaneous or open procedures (p = 0.07). The median (Q1, Q3) time to aortic occlusion in REBOA once arterial access had been established was 245 seconds (179, 295.5 seconds), which was significantly shorter than RTACC (p = 0.003). CONCLUSIONS: Once CFA access is achieved, time to aortic occlusion is faster with REBOA. Time to aortic occlusion is less than the time required to cannulate the CFA either by percutaneous or open approaches, emphasizing the importance of accurate and expedient CFA access. Resuscitative endovascular balloon occlusion of the aorta may represent a feasible alternative to thoracotomy for aortic occlusion. Time to aortic occlusion will likely decrease with the advent of newer REBOA technology. The rate-limiting portion of REBOA continues to be obtaining CFA access. LEVEL OF EVIDENCE: Therapeutic, level V. PMID- 29190257 TI - The trauma center is too late: Major limb trauma without a pre-hospital tourniquet has increased death from hemorrhagic shock. AB - BACKGROUND: To date, no civilian studies have demonstrated that pre-hospital (PH) tourniquets improve survival. We hypothesized that late, trauma center (TC) tourniquet use would increase death from hemorrhagic shock compared to early (PH) placement. METHODS: All patients arriving to a Level 1, urban TC between October 2008 and January 2016 with a tourniquet placed before (T-PH) or after arrival to the TC (T-TC) were evaluated. Cases were assigned the following designations: indicated (absolute indication [vascular injury requiring repair/ligation, operation within 2 hours for extremity injury, or traumatic amputation] or relative indication [major musculoskeletal/soft tissue injury requiring operation 2-8 hours after arrival, documented large blood loss]) or non-indicated. Outcomes were death from hemorrhagic shock, physiology upon arrival to the TC, and massive transfusion requirements. After univariate analysis, logistic regression was carried out to assess independent predictors of death from hemorrhagic shock. RESULTS: A total of 306 patients received 326 tourniquets for injuries to 157 upper and 147 lower extremities. Two hundred eighty-one (92%) had an indication for placement. Seventy percent of patients had a blunt mechanism of injury. T-TC patients arrived with a lower systolic blood pressure (SBP, 101 [86, 123] vs. 125 [100, 145] mm Hg, p < 0.001), received more transfusions in the first hour of arrival (55% vs. 34%, p = 0.02), and had a greater mortality from hemorrhagic shock (14% vs. 3.0%, p = 0.01). When controlling for year of admission, mechanism of injury and shock upon arrival (SBP <=90 mm Hg or HR >=120 bpm or base deficit <= 4) indicated T-TC had a 4.5-fold increased odds of death compared to T-PH (OR 4.5, 95% CI 1.23-16.4, p = 0.02). CONCLUSIONS: Waiting until TC arrival to control hemorrhage with a tourniquet was associated with worsened blood pressure and increased transfusion within the first hour of arrival. In routine civilian trauma patients, delaying to T-TC was associated with 4.5-fold increased odds of mortality from hemorrhagic shock. LEVEL OF EVIDENCE: Level IV.

AB - BACKGROUND The use of a stent during the acute post-hemorrhage period is controversial. We conducted a retrospective analysis on the clinical and angiographic outcomes of the ruptured aneurysms that were embolized with stent assisted coiling or coiling-only. MATERIAL AND METHODS We reviewed data of 279 patients with 279 ruptured intracranial aneurysms who underwent coil embolization between July 2004 and June 2015. The baseline data on age, sex, medical history, aneurysm size, location, and Hunt and Hess grade were recorded. RESULTS One hundred and thirteen aneurysms were treated with stent-assisted coiling. Adverse events occurred in similar proportions of patients in the two groups (11.5% in the stenting group and 9.0% in the coiling alone group). The incidence of permanent disabling neurologic deficit was also similar in the two groups (7.1% and 5.4% in the stenting group and coiling alone group respectively). Clinical follow-up data were available in 207 patients with a median period of 28 months. Angiographic follow-up was available in 106 aneurysms with a median period of 7.5 months. Clinical outcomes were correlated with adverse events (p=0.043, odds ratio=4.59), large aneurysms (p=0.013, odds ratio=10.24), and Hunt and Hess grade (p=0.001, odds ratio=13.51). Stent-assisted coiling for ruptured aneurysm, as compared with coiling-only, was not associated with an increased incidence of poor clinical outcome at follow-up. Aneurysm-occlusion status at follow-up were correlated with stent placement (p<0.001, odds ratio=5.85) and initial aneurysm occlusion status (p=0.027, odds ratio=3.78). CONCLUSIONS Compared with coiling only, stent-assisted coil placement may have better durability, with comparable safety for ruptured intracranial aneurysm.

PMID- 29190263 TI - Scale-Up of Voluntary Medical Male Circumcision Services for HIV Prevention - 12 Countries in Southern and Eastern Africa, 2013-2016. AB - Countries in Southern and Eastern Africa have the highest prevalence of human immunodeficiency virus (HIV) infection in the world; in 2015, 52% (approximately 19 million) of all persons living with HIV infection resided in these two regions.* Voluntary medical male circumcision (VMMC) reduces the risk for heterosexually acquired HIV infection among males by approximately 60% (1). As such, it is an essential component of the Joint United Nations Programme on HIV/AIDS (UNAIDS) strategy for ending acquired immunodeficiency syndrome (AIDS) by 2030 (2). Substantial progress toward achieving VMMC targets has been made in the 10 years since the World Health Organization (WHO) and UNAIDS recommended scale-up of VMMC for HIV prevention in 14 Southern and Eastern African countries with generalized HIV epidemics and low male circumcision prevalence (3).? This has been enabled in part by nearly $2 billion in cumulative funding through the President's Emergency Plan for AIDS Relief (PEPFAR), administered through multiple U.S. governmental agencies, including CDC, which has supported nearly half of all PEPFAR-supported VMMCs to date. Approximately 14.5 million VMMCs were performed globally during 2008-2016, which represented 70% of the original target of 20.8 million VMMCs in males aged 15-49 years through 2016 (4). Despite falling short of the target, these VMMCs are projected to avert 500,000 HIV infections by the end of 2030 (4). However, UNAIDS has estimated an additional 27 million VMMCs need to be performed by 2021 to meet the Fast Track targets (2). This report updates a previous report covering the period 2010-2012, when VMMC implementing partners supported by CDC performed approximately 1 million VMMCs in nine countries (5). During 2013-2016, these implementing partners performed nearly 5 million VMMCs in 12 countries. Meeting the global target will require redoubling current efforts and introducing novel strategies that increase demand among subgroups of males who have historically been reluctant to undergo VMMC. PMID- 29190264 TI - Fractional-Dose Inactivated Poliovirus Vaccine Campaign - Sindh Province, Pakistan, 2016. AB - Following the declaration of eradication of wild poliovirus (WPV) type 2 in September 2015, trivalent oral poliovirus vaccine (tOPV) was withdrawn globally to reduce the risk for type 2 vaccine-derived poliovirus (VDPV2) transmission; all countries implemented a synchronized switch to bivalent OPV (type 1 and 3) in April 2016 (1,2). Any isolation of VDPV2 after the switch is to be treated as a potential public health emergency and might indicate the need for supplementary immunization activities (3,4). On August 9, 2016, VDPV2 was isolated from a sewage sample taken from an environmental surveillance site in Hyderabad, Sindh province, Pakistan. Possible vaccination activities in response to VDPV2 isolation include the use of injectable inactivated polio vaccine (IPV), which poses no risk for vaccine-derived poliovirus transmission. Fractional-dose, intradermal IPV (fIPV), one fifth of the standard intramuscular dose, has been developed to more efficiently manage limited IPV supplies. fIPV has been shown in some studies to be noninferior to full-dose IPV (5,6) and was used successfully in response to a similar detection of a single VDPV2 isolate from sewage in India (7). Injectable fIPV was used for response activities in Hyderabad and three neighboring districts. This report describes the findings of an assessment of preparatory activities and subsequent implementation of the fIPV campaign. Despite achieving high coverage (>80%), several operational challenges were noted. The lessons learned from this campaign could help to guide the planning and implementation of future fIPV vaccination activities.

AB - The percentage of U.S. adults aged 20-64 years who had a fasting test for high blood sugar or diabetes in the past 12 months increased from 39.7% in 2011 to 45.7% in 2016. From 2011 to 2016, there was an increase in the percentage for all racial/ethnic groups examined: Hispanic (38.3% to 43.0%), non-Hispanic white (39.6% to 46.5%), non-Hispanic black (41.2% to 44.9%), and non-Hispanic Asian (41.5% to 49.6%) adults. In 2011, there was no statistically significant difference among the four groups examined, but in 2016, Hispanic adults were less likely than non-Hispanic white and non-Hispanic Asian adults to have had a fasting test, and non-Hispanic Asian adults were more likely than non-Hispanic black adults to have had one.

PMID- 29190267 TI - Vital Signs: Human Immunodeficiency Virus Testing and Diagnosis Delays - United States. AB - BACKGROUND: Persons unaware of their human immunodeficiency virus (HIV) infection account for approximately 40% of ongoing transmissions in the United States. Persons are unaware of their infection because of delayed HIV diagnoses that represent substantial missed opportunities to improve health outcomes and prevent HIV transmission. METHODS: Data from CDC's National HIV Surveillance System were used to estimate, among persons with HIV infection diagnosed in 2015, the median interval (and range) from infection to diagnosis (diagnosis delay), based on the first CD4 test after HIV diagnosis and a CD4 depletion model indicating disease progression and, among persons living with HIV in 2015, the percentage with undiagnosed infection. Data from CDC's National HIV Behavioral Surveillance were analyzed to determine the percentage of persons at increased risk for HIV infection who had tested in the past 12 months and who had missed opportunities for testing. RESULTS: An estimated 15% of persons living with HIV in 2015 were unaware of their infection. Among the 39,720 persons with HIV infection diagnosed in 2015, the estimated median diagnosis delay was 3.0 years (interquartile range = 0.7-7.8 years); diagnosis delay varied by race/ethnicity (from 2.2 years among whites to 4.2 years among Asians) and transmission category (from 2.0 years among females who inject drugs to 4.9 years among heterosexual males). Among persons interviewed through National HIV Behavioral Surveillance, 71% of men who have sex with men, 58% of persons who inject drugs, and 41% of heterosexual persons at increased risk for HIV infection reported testing in the past 12 months. In each risk group, at least two thirds of persons who did not have an HIV test had seen a health care provider in the past year. CONCLUSIONS: Delayed HIV diagnoses continue to be substantial for some population groups and prevent early entry to care to improve health outcomes and reduce HIV transmission to others. IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Health care providers and others providing HIV testing can reduce HIV-related adverse health outcomes and risk for HIV transmission by implementing routine and targeted HIV testing to decrease diagnosis delays.

AB - Synthetic cannabinoids (SCs), commonly known by the street name "Spice," are designer drugs of abuse that mimic the psychoactive effects of marijuana. Intentional SC use has resulted in multiple toxicities (1,2), but little is known about occupational SC exposure. After a federal agency's law enforcement personnel in Nevada reported irritability and feeling "high" after raiding illegal SC laboratories and processing seized SCs, a request for a health hazard evaluation was made by the agency to CDC's National Institute for Occupational Safety and Health (NIOSH) in 2014 to evaluate agents' occupational SC exposures. After making the request for a health hazard evaluation, federal agents conducted a raid of an illegal SC laboratory, with assistance from local law enforcement and Drug Enforcement Administration (DEA) personnel and with NIOSH investigators observing from a distance. After the raid, agents collected and processed material evidence. NIOSH investigators tested agents' urine for SC levels before and after the raid and measured SCs in the air and on surfaces after the raid. DEA determined that AB-PINACA (an SC compound) and mitragynine (a plant material with opium-like effects, also known as "kratom") were present in the illegal laboratory. AB-PINACA, its metabolites, and mitragynine were not detected in agents' urine before the raid; however, one or more of these substances was found in the urine of six of nine agents after the raid and processing of the SC evidence. AB-PINACA was detected in one surface wipe sample from the SC laboratory; none was detected in the air in the laboratory or in the offices of the law enforcement agency where the materials were processed after the raid. No policies were in place regarding work practices and use of personal protective equipment (PPE) during raids and evidence processing. To protect agents from SC exposures, NIOSH recommended that the agency require agents to wear a minimum level of PPE (e.g., protective gloves and disposable clothing) and undergo training in PPE and in handling and storing of contaminated evidence from SC laboratory raids. Showers and locker rooms also need to be provided so that agents can reduce contamination and prevent take-home exposure. PMID- 29190269 TI - SPOTs fill a major gap in RNA quantification.

AB - Light of different wavelengths is essential for plant growth and development. Short-wavelength radiation such as UV can shift the composition of flavonoids, glucosinolates, and other plant metabolites responsible for enhanced defense against certain herbivorous insects. The intensity of light-induced, metabolite based resistance is plant- and insect species-specific and depends on herbivore feeding guild and specialization. The increasing use of light-emitting diodes (LEDs) in horticultural plant production systems in protected environments enables the creation of tailor-made light scenarios for improved plant cultivation and induced defense against herbivorous insects. In this study, broccoli (Brassica oleracea var. italica) plants were grown in a climate chamber under broad spectra photosynthetic active radiation (PAR) and were additionally treated with the following narrow-bandwidth light generated with LEDs: UV-A (365 nm), violet (420 nm), blue (470 nm), or green (515 nm). We determined the influence of narrow-bandwidth light on broccoli plant growth, secondary plant metabolism (flavonol glycosides and glucosinolates), and plant-mediated light effects on the performance and behavior of the specialized cabbage aphid Brevicoryne brassicae. Green light increased plant height more than UV-A, violet, or blue LED treatments. Among flavonol glycosides, specific quercetin and kaempferol glycosides were increased under violet light. The concentration of 3 indolylmethyl glucosinolate in plants was increased by UV-A treatment. B. brassicae performance was not influenced by the different light qualities, but in host-choice tests, B. brassicae preferred previously blue-illuminated plants (but not UV-A-, violet-, or green-illuminated plants) over control plants.

AB - In this research, the social behavior of the participants in a Prisoner's Dilemma laboratory game is explained on the basis of the quantal response equilibrium concept and the representation of the game in Markov strategies. In previous research, we demonstrated that social interaction during the experiment has a positive influence on cooperation, trust, and gratefulness. This research shows that the quantal response equilibrium concept agrees only with the results of experiments on cooperation in Prisoner's Dilemma prior to social interaction. However, quantal response equilibrium does not explain of participants' behavior after social interaction. As an alternative theoretical approach, an examination was conducted of iterated Prisoner's Dilemma game in Markov strategies. We built a totally mixed Nash equilibrium in this game; the equilibrium agrees with the results of the experiments both before and after social interaction. PMID- 29190279 TI - malERA: An updated research agenda for characterising the reservoir and measuring transmission in malaria elimination and eradication. AB - This paper summarises key advances in defining the infectious reservoir for malaria and the measurement of transmission for research and programmatic use since the Malaria Eradication Research Agenda (malERA) publication in 2011. Rapid and effective progress towards elimination requires an improved understanding of the sources of transmission as well as those at risk of infection. Characterising the transmission reservoir in different settings will enable the most appropriate choice, delivery, and evaluation of interventions. Since 2011, progress has been made in a number of areas. The extent of submicroscopic and asymptomatic infections is better understood, as are the biological parameters governing transmission of sexual stage parasites. Limitations of existing transmission measures have been documented, and proof-of-concept has been established for new innovative serological and molecular methods to better characterise transmission. Finally, there now exists a concerted effort towards the use of ensemble datasets across the spectrum of metrics, from passive and active sources, to develop more accurate risk maps of transmission. These can be used to better target interventions and effectively monitor progress toward elimination. The success of interventions depends not only on the level of endemicity but also on how rapidly or recently an area has undergone changes in transmission. Improved understanding of the biology of mosquito-human and human-mosquito transmission is needed particularly in low-endemic settings, where heterogeneity of infection is pronounced and local vector ecology is variable. New and improved measures of transmission need to be operationally feasible for the malaria programmes. Outputs from these research priorities should allow the development of a set of approaches (applicable to both research and control programmes) that address the unique challenges of measuring and monitoring transmission in near-elimination settings and defining the absence of transmission. PMID- 29190277 TI - malERA: An updated research agenda for basic science and enabling technologies in malaria elimination and eradication. AB - Basic science holds enormous power for revealing the biological mechanisms of disease and, in turn, paving the way toward new, effective interventions. Recognizing this power, the 2011 Research Agenda for Malaria Eradication included key priorities in fundamental research that, if attained, could help accelerate progress toward disease elimination and eradication. The Malaria Eradication Research Agenda (malERA) Consultative Panel on Basic Science and Enabling Technologies reviewed the progress, continuing challenges, and major opportunities for future research. The recommendations come from a literature of published and unpublished materials and the deliberations of the malERA Refresh Consultative Panel. These areas span multiple aspects of the Plasmodium life cycle in both the human host and the Anopheles vector and include critical, unanswered questions about parasite transmission, human infection in the liver, asexual-stage biology, and malaria persistence. We believe an integrated approach encompassing human immunology, parasitology, and entomology, and harnessing new and emerging biomedical technologies offers the best path toward addressing these questions and, ultimately, lowering the worldwide burden of malaria. PMID- 29190281 TI - Internet-based biosurveillance methods for vector-borne diseases: Are they novel public health tools or just novelties? AB - Internet-based surveillance methods for vector-borne diseases (VBDs) using "big data" sources such as Google, Twitter, and internet newswire scraping have recently been developed, yet reviews on such "digital disease detection" methods have focused on respiratory pathogens, particularly in high-income regions. Here, we present a narrative review of the literature that has examined the performance of internet-based biosurveillance for diseases caused by vector-borne viruses, parasites, and other pathogens, including Zika, dengue, other arthropod-borne viruses, malaria, leishmaniasis, and Lyme disease across a range of settings, including low- and middle-income countries. The fundamental features, advantages, and drawbacks of each internet big data source are presented for those with varying familiarity of "digital epidemiology." We conclude with some of the challenges and future directions in using internet-based biosurveillance for the surveillance and control of VBD.

AB - The Sonic Kayak is a musical instrument used to investigate nature and developed during open hacklab events. The kayaks are rigged with underwater environmental sensors, which allow paddlers to hear real-time water temperature sonifications and underwater sounds, generating live music from the marine world. Sensor data is also logged every second with location, time and date, which allows for fine scale mapping of water temperatures and underwater noise that was previously unattainable using standard research equipment. The system can be used as a citizen science data collection device, research equipment for professional scientists, or a sound art installation in its own right. PMID- 29190282 TI - Experience-dependent olfactory behaviors of the parasitic nematode Heligmosomoides polygyrus. AB - Parasitic nematodes of humans and livestock cause extensive disease and economic loss worldwide. Many parasitic nematodes infect hosts as third-stage larvae, called iL3s. iL3s vary in their infection route: some infect by skin penetration, others by passive ingestion. Skin-penetrating iL3s actively search for hosts using host-emitted olfactory cues, but the extent to which passively ingested iL3s respond to olfactory cues was largely unknown. Here, we examined the olfactory behaviors of the passively ingested murine gastrointestinal parasite Heligmosomoides polygyrus. H. polygyrus iL3s were thought to reside primarily on mouse feces, and infect when mice consume feces containing iL3s. However, iL3s can also adhere to mouse fur and infect orally during grooming. Here, we show that H. polygyrus iL3s are highly active and show robust attraction to host feces. Despite their attraction to feces, many iL3s migrate off feces to engage in environmental navigation. In addition, H. polygyrus iL3s are attracted to mammalian skin odorants, suggesting that they migrate toward hosts. The olfactory preferences of H. polygyrus are flexible: some odorants are repulsive for iL3s maintained on feces but attractive for iL3s maintained off feces. Experience dependent modulation of olfactory behavior occurs over the course of days and is mediated by environmental carbon dioxide (CO2) levels. Similar experience dependent olfactory plasticity occurs in the passively ingested ruminant parasitic nematode Haemonchus contortus, a major veterinary parasite. Our results suggest that passively ingested iL3s migrate off their original fecal source and actively navigate toward hosts or new host fecal sources using olfactory cues. Olfactory plasticity may be a mechanism that enables iL3s to switch from dispersal behavior to host-seeking behavior. Together, our results demonstrate that passively ingested nematodes do not remain inactive waiting to be swallowed, but rather display complex sensory-driven behaviors to position themselves for host ingestion. Disrupting these behaviors may be a new avenue for preventing infections. PMID- 29190284 TI - Listeria monocytogenes switches from dissemination to persistence by adopting a vacuolar lifestyle in epithelial cells. AB - Listeria monocytogenes causes listeriosis, a foodborne disease that poses serious risks to fetuses, newborns and immunocompromised adults. This intracellular bacterial pathogen proliferates in the host cytosol and exploits the host actin polymerization machinery to spread from cell-to-cell and disseminate in the host. Here, we report that during several days of infection in human hepatocytes or trophoblast cells, L. monocytogenes switches from this active motile lifestyle to a stage of persistence in vacuoles. Upon intercellular spread, bacteria gradually stopped producing the actin-nucleating protein ActA and became trapped in lysosome-like vacuoles termed Listeria-Containing Vacuoles (LisCVs). Subpopulations of bacteria resisted degradation in LisCVs and entered a slow/non replicative state. During the subculture of host cells harboring LisCVs, bacteria showed a capacity to cycle between the vacuolar and the actin-based motility stages. When ActA was absent, such as in DeltaactA mutants, vacuolar bacteria parasitized host cells in the so-called "viable but non-culturable" state (VBNC), preventing their detection by conventional colony counting methods. The exposure of infected cells to high doses of gentamicin did not trigger the formation of LisCVs, but selected for vacuolar and VBNC bacteria. Together, these results reveal the ability of L. monocytogenes to enter a persistent state in a subset of epithelial cells, which may favor the asymptomatic carriage of this pathogen, lengthen the incubation period of listeriosis, and promote bacterial survival during antibiotic therapy. PMID- 29190285 TI - The interplay of UV and cutaneous papillomavirus infection in skin cancer development. AB - Cutaneous human papillomaviruses (HPVs) are considered as cofactors for non melanoma skin cancer (NMSC) development, especially in association with UVB. Extensively studied transgenic mouse models failed to mimic all aspects of virus host interactions starting from primary infection to the appearance of a tumor. Using the natural model Mastomys coucha, which reflects the human situation in many aspects, we provide the first evidence that only UVB and Mastomys natalensis papillomavirus (MnPV) infection strongly promote NMSC formation. Using UVB exposures that correspond to UV indices of different geographical regions, irradiated animals developed either well-differentiated keratinizing squamous cell carcinomas (SCCs), still supporting productive infections with high viral loads and transcriptional activity, or poorly differentiated non-keratinizing SCCs almost lacking MnPV DNA and in turn, early and late viral transcription. Intriguingly, animals with the latter phenotype, however, still showed strong seropositivity, clearly verifying a preceding MnPV infection. Of note, the mere presence of MnPV could induce gammaH2AX foci, indicating that viral infection without prior UVB exposure can already perturb genome stability of the host cell. Moreover, as shown both under in vitro and in vivo conditions, MnPV E6/E7 expression also attenuates the excision repair of cyclobutane pyrimidine dimers upon UVB irradiation, suggesting a viral impact on the DNA damage response. While mutations of Ras family members (e.g. Hras, Kras, and Nras) were absent, the majority of SCCs harbored-like in humans-Trp53 mutations especially at two hot spots in the DNA-binding domain, resulting in a loss of function that favored tumor dedifferentiation, counter-selective for viral maintenance. Such a constellation provides a reasonable explanation for making continuous viral presence dispensable during skin carcinogenesis as observed in patients with NMSC. PMID- 29190286 TI - Nucleolar sub-compartments in motion during rRNA synthesis inhibition: Contraction of nucleolar condensed chromatin and gathering of fibrillar centers are concomitant. AB - The nucleolus produces the large polycistronic transcript (47S precursor) containing the 18S, 5.8S and 28S rRNA sequences and hosts most of the nuclear steps of pre-rRNA processing. Among numerous components it contains condensed chromatin and active rRNA genes which adopt a more accessible conformation. For this reason, it is a paradigm of chromosome territory organization. Active rRNA genes are clustered within several fibrillar centers (FCs), in which they are maintained in an open configuration by Upstream Binding Factor (UBF) molecules. Here, we used the reproducible reorganization of nucleolar components induced by the inhibition of rRNA synthesis by Actinomycin D (AMD) to address the steps of the spatiotemporal reorganization of FCs and nucleolar condensed chromatin. To reach that goal, we used two complementary approaches: i) time-lapse confocal imaging of cells expressing one or several GFP-tagged proteins (fibrillarin, UBF, histone H2B) and ii) ultrastructural identification of nucleolar components involved in the reorganization. Data obtained by time lapse confocal microscopy were analyzed through detailed 3D imaging. This allowed us to demonstrate that AMD treatment induces no fusion and no change in the relative position of the different nucleoli contained in one nucleus. In contrast, for each nucleolus, we observed step by step gathering and fusion of both FCs and nucleolar condensed chromatin. To analyze the reorganization of FCs and condensed chromatin at a higher resolution, we performed correlative light and electron microscopy electron microscopy (CLEM) imaging of the same cells. We demonstrated that threads of intranucleolar condensed chromatin are localized in a complex 3D network of vacuoles. Upon AMD treatment, these structures coalesce before migrating toward the perinucleolar condensed chromatin, to which they finally fuse. During their migration, FCs, which are all linked to ICC, are pulled by the latter to gather as caps disposed at the periphery of nucleoli. PMID- 29190287 TI - Discovery of a rich gene pool of bat SARS-related coronaviruses provides new insights into the origin of SARS coronavirus. AB - A large number of SARS-related coronaviruses (SARSr-CoV) have been detected in horseshoe bats since 2005 in different areas of China. However, these bat SARSr CoVs show sequence differences from SARS coronavirus (SARS-CoV) in different genes (S, ORF8, ORF3, etc) and are considered unlikely to represent the direct progenitor of SARS-CoV. Herein, we report the findings of our 5-year surveillance of SARSr-CoVs in a cave inhabited by multiple species of horseshoe bats in Yunnan Province, China. The full-length genomes of 11 newly discovered SARSr-CoV strains, together with our previous findings, reveals that the SARSr-CoVs circulating in this single location are highly diverse in the S gene, ORF3 and ORF8. Importantly, strains with high genetic similarity to SARS-CoV in the hypervariable N-terminal domain (NTD) and receptor-binding domain (RBD) of the S1 gene, the ORF3 and ORF8 region, respectively, were all discovered in this cave. In addition, we report the first discovery of bat SARSr-CoVs highly similar to human SARS-CoV in ORF3b and in the split ORF8a and 8b. Moreover, SARSr-CoV strains from this cave were more closely related to SARS-CoV in the non structural protein genes ORF1a and 1b compared with those detected elsewhere. Recombination analysis shows evidence of frequent recombination events within the S gene and around the ORF8 between these SARSr-CoVs. We hypothesize that the direct progenitor of SARS-CoV may have originated after sequential recombination events between the precursors of these SARSr-CoVs. Cell entry studies demonstrated that three newly identified SARSr-CoVs with different S protein sequences are all able to use human ACE2 as the receptor, further exhibiting the close relationship between strains in this cave and SARS-CoV. This work provides new insights into the origin and evolution of SARS-CoV and highlights the necessity of preparedness for future emergence of SARS-like diseases. PMID- 29190288 TI - Hematologic and biochemical differences between two free ranging Yangtze finless porpoise populations: The implications of habitat. AB - The goals of this study were to compare the serum chemistry and hematology values of wild and semi-natural free-ranging Yangtze Finless Porpoises (Neophocaena asiaeorientalis ssp. asiaeorientalis) populations and to ascertain how these values change with the different environmental condition. For this study, samples were collected from 81 YFPs, 35 living in the wild and 46 living in a semi natural reserve. Each population was divided into 8 life history categories; Male Calf, Female Calf, Juvenile Male, Juvenile Female, Adult Male, Pregnant, Lactating and Pregnant plus Lactating. Statistically significant differences in the various parameters were observed in the same life history categories for both populations. Generally, Lipid Profile, Hepatic Enzymes, Creatine Kinase, Red Blood Cells, Hemoglobin, Hematocrit and Neutrophils were significantly higher in the Tian-E-Zhou Oxbow population while, Creatinine, Phosphate, Lactate Dehydrogenase, Bilirubin and Lymphocytes were significantly higher in the Poyang Lake YFPs. Across the groups in the Tian-E-Zhou Oxbow population, a significant decrease in serum Albumin, Alkaline Phosphatase and Calcium, while a significant increase in the Neutrophils and Platelets was observed. Similarly, in the Poyang Lake, Alkaline Phosphatase levels in the Female Calves group, High Density Lipoprotein Cholesterol in Lactating group, basophil counts in Pregnant plus Lactating group, lymphocytes counts in Juvenile Females group and Globulin and Total Protein levels in Pregnant group were significantly higher. This study in health assessments can help us to understand the effect of sex, age, reproductive status and environmental conditions on the well-being of Yangtze Finless Porpoises. PMID- 29190289 TI - malERA: An updated research agenda for health systems and policy research in malaria elimination and eradication. AB - Health systems underpin disease elimination and eradication programmes. In an elimination and eradication context, innovative research approaches are needed across health systems to assess readiness for programme reorientation, mitigate any decreases in effectiveness of interventions ('effectiveness decay'), and respond to dynamic and changing needs. The malaria eradication research agenda (malERA) Refresh consultative process for the Panel on Health Systems and Policy Research identifies opportunities to build health systems evidence and the tools needed to eliminate malaria from different zones, countries, and regions and to eradicate it globally. The research questions are organised as a portfolio that global health practitioners, researchers, and funders can identify with and support. This supports the promotion of an actionable and more cohesive approach to building the evidence base for scaled-up implementation of findings. Gaps and opportunities discussed in the paper include delivery strategies to meet the changing dynamics of needs of individuals, environments, and malaria programme successes; mechanisms and approaches to best support accelerated policy and financial responsiveness at national and global level to ensure timely response to evidence and needs, including in crisis situations; and systems' readiness tools and decision-support systems. PMID- 29190290 TI - Skeletal muscle mitochondrial bioenergetics and associations with myostatin genotypes in the Thoroughbred horse. AB - Variation in the myostatin (MSTN) gene has been reported to be associated with race distance, body composition and skeletal muscle fibre composition in the horse. The aim of the present study was to test the hypothesis that MSTN variation influences mitochondrial phenotypes in equine skeletal muscle. Mitochondrial abundance and skeletal muscle fibre types were measured in whole muscle biopsies from the gluteus medius of n = 82 untrained (21 +/- 3 months) Thoroughbred horses. Skeletal muscle fibre type proportions were significantly (p < 0.01) different among the three MSTN genotypes and mitochondrial content was significantly (p < 0.01) lower in the combined presence of the C-allele of SNP g.66493737C>T (C) and the SINE insertion 227 bp polymorphism (I). Evaluation of mitochondrial complex activities indicated higher combined mitochondrial complex I+III and II+III activities in the presence of the C-allele / I allele (p <= 0.05). The restoration of complex I+III and complex II+III activities following addition of exogenous coenzyme Q1 (ubiquinone1) (CoQ1) in vitro in the TT/NN (homozygous T allele/homozygous no insertion) cohort indicated decreased coenzyme Q in these animals. In addition, decreased gene expression in two coenzyme Q (CoQ) biosynthesis pathway genes (COQ4, p <= 0.05; ADCK3, p <= 0.01) in the TT/NN horses was observed. This study has identified several mitochondrial phenotypes associated with MSTN genotype in untrained Thoroughbred horses and in addition, our findings suggest that nutritional supplementation with CoQ may aid to restore coenzyme Q activity in TT/NN horses. PMID- 29190292 TI - TNF-alpha blockade suppresses pericystic inflammation following anthelmintic treatment in porcine neurocysticercosis. AB - BACKGROUND: Neurocysticercosis (NCC) is an infection of the brain with the larval cyst of the tapeworm, Taenia solium. Cysticidal treatment induces parasite killing resulting in a post inflammatory response and seizures, which generally requires corticosteroid treatment to control inflammation. The nature of this response and how to best control it is unclear. We investigated the anti inflammatory effects of pretreatment with etanercept (ETN), an anti-tumor necrosis factor agent, or dexamethasone (DEX), a high potency corticosteroid, on the post treatment inflammatory response in naturally infected pigs with neurocysticercosis after a single dose of the cysticidal drug praziquantel (PZQ). METHODOLOGY/PRINCIPAL FINDINGS: We followed the methods from a previously developed treatment model of NCC in naturally infected swine. The four study groups of infected pigs included 3 groups treated with PZQ on day 0: PZQ-treated alone (100 mg/kg PO; n = 9), pretreated with dexamethasone (DEX, 0.2 mg/kg IM administered on days -1, +1 and +3; n = 6), and pretreated with etanercept (ETN, 25 mg IM per animal on days -7 and 0; n = 6). The fourth group remained untreated (n = 3). As measured by quantitative RT-PCR, ETN pretreatment depressed transcription of a wide range of proinflammatory, regulatory and matrix protease encoding genes at 120 hr post PZQ treatment in capsules of cysts that demonstrated extravasated Evans Blue (EB) (a measure of blood brain barrier dysfunction) compared to animals not receiving ETN. Transcription was significantly depressed for the proinflammatory genes tumor necrosis factor (TNF) alpha, and interferon (IFN)-gamma; the inflammation regulating genes cytotoxic T lymphocyte-associated protein (CTLA)4, interleukin (IL)-13 and transforming growth factor (TGF)-beta; the tissue remodeling genes matrix metalloprotease (MMP)1 and 9, tissue inhibitors of metalloproteases (TIMP)1 and 2, and the genes regulating endothelial function vascular endothelial growth factor (VEGF)1, angiopoietin (Ang)1, Ang 2, and platelet endothelial cell adhesion molecule (PECAM)-1. In contrast, transcription was only modestly decreased in the DEX pretreated pigs compared to PZQ alone, and only for TNF-alpha, IL-6, IFN-gamma, TGF-beta and Ang1. IL-10 was not affected by either ETN or DEX pretreatments. The degree of inflammation, assessed by semi-quantitative inflammatory scores, was modestly decreased in both ETN and DEX pretreated animals compared to PZQ treated pigs whereas cyst damage scores were moderately decreased only in cysts from DEX pretreated pigs. However, the proportion of cysts with EB extravasation was not significantly changed in ETN and DEX pretreated groups. CONCLUSIONS/SIGNIFICANCE: Overall, TNF-alpha blockade using ETN treatment modulated expression of a large variety of genes that play a role in induction and control of inflammation and structural changes. In contrast the number of inflammatory cells was only moderately decreased suggesting weaker effects on cell migration into the inflammatory capsules surrounding cysts than on release of modulatory molecules. Taken together, these data suggest that TNF-alpha blockade may provide a viable strategy to manage post-treatment pericystic inflammation that follows antiparasitic therapy for neurocysticercosis. PMID- 29190293 TI - Morphological correlation between caloric tests and vestibular hydrops in Meniere's disease using intravenous Gd enhanced inner ear MRI. AB - The purpose of this study was to prove the hypothesis that caloric response in Meniere's disease (MD) is reduced by hydropic expansion of the vestibular labyrinth, not by vestibular hypofunction, by evaluating the correlation morphologically using an intravenous Gadolinium (IV-Gd) inner ear MRI. In study I, the prevalence of abnormal video Head Impulse Test (vHIT) results among the patients with definite unilateral MD (n = 24) and vestibular neuritis (VN) (n = 22) were investigated. All patients showed abnormal canal paresis (CP) (> 26%) on caloric tests. The prevalence of abnormal vHIT in patients with abnormal CP was significantly lower in MD patients (12.5%) than that in VN patients (81.8%) (p < 0.001). In study II, morphological correlation between caloric tests and vestibular hydrops level was evaluated in unilateral MD patients (n = 16) who had normal vHIT results. Eleven patients (61%) had abnormal CP. After taking the images of IV-Gd inner ear MRI, the vestibular hydrops ratio (endolymph volume/total lymph volume = %VH) was measured. In addition, the relative vestibular hydrops ratio (%RVH = (%VHaffected ear-%VHunaffected ear) / (%VHaffected ear + %VHunaffected ear)) was calculated. Each ratio (%VH and %RVH) was compared with average peak slow phase velocity (PSPV) and CP, respectively. In the MD patients, %VH of the affected ear correlated significantly with mean PSPV on the same side (rs = -0.569, p = 0.024), while %RVH correlated significantly with CP (rs = 0.602, p = 0.014). In most MD patients (87.5%) compared to VN patients, vHIT results were normal even though the caloric function was reduced. In addition, the reduced caloric function with normal vHIT was related to the severity of the vestibular hydrops measured by the IV-Gd inner ear MRI. These findings concluded that the abnormal caloric tests with normal vHIT in MD indicated severe endolymphatic hydrops rather than vestibular hypofunction. PMID- 29190291 TI - malERA: An updated research agenda for diagnostics, drugs, vaccines, and vector control in malaria elimination and eradication. AB - Since the turn of the century, a remarkable expansion has been achieved in the range and effectiveness of products and strategies available to prevent, treat, and control malaria, including advances in diagnostics, drugs, vaccines, and vector control. These advances have once again put malaria elimination on the agenda. However, it is clear that even with the means available today, malaria control and elimination pose a formidable challenge in many settings. Thus, currently available resources must be used more effectively, and new products and approaches likely to achieve these goals must be developed. This paper considers tools (both those available and others that may be required) to achieve and maintain malaria elimination. New diagnostics are needed to direct treatment and detect transmission potential; new drugs and vaccines to overcome existing resistance and protect against clinical and severe disease, as well as block transmission and prevent relapses; and new vector control measures to overcome insecticide resistance and more powerfully interrupt transmission. It is also essential that strategies for combining new and existing approaches are developed for different settings to maximise their longevity and effectiveness in areas with continuing transmission and receptivity. For areas where local elimination has been recently achieved, understanding which measures are needed to maintain elimination is necessary to prevent rebound and the reestablishment of transmission. This becomes increasingly important as more countries move towards elimination. PMID- 29190294 TI - CNGCs break through-A rice cyclic nucleotide-gated channel paves the way for pollen tube growth. PMID- 29190296 TI - Evaluating Bayesian spatial methods for modelling species distributions with clumped and restricted occurrence data. AB - Statistical approaches for inferring the spatial distribution of taxa (Species Distribution Models, SDMs) commonly rely on available occurrence data, which is often clumped and geographically restricted. Although available SDM methods address some of these factors, they could be more directly and accurately modelled using a spatially-explicit approach. Software to fit models with spatial autocorrelation parameters in SDMs are now widely available, but whether such approaches for inferring SDMs aid predictions compared to other methodologies is unknown. Here, within a simulated environment using 1000 generated species' ranges, we compared the performance of two commonly used non-spatial SDM methods (Maximum Entropy Modelling, MAXENT and boosted regression trees, BRT), to a spatial Bayesian SDM method (fitted using R-INLA), when the underlying data exhibit varying combinations of clumping and geographic restriction. Finally, we tested how any recommended methodological settings designed to account for spatially non-random patterns in the data impact inference. Spatial Bayesian SDM method was the most consistently accurate method, being in the top 2 most accurate methods in 7 out of 8 data sampling scenarios. Within high-coverage sample datasets, all methods performed fairly similarly. When sampling points were randomly spread, BRT had a 1-3% greater accuracy over the other methods and when samples were clumped, the spatial Bayesian SDM method had a 4%-8% better AUC score. Alternatively, when sampling points were restricted to a small section of the true range all methods were on average 10-12% less accurate, with greater variation among the methods. Model inference under the recommended settings to account for autocorrelation was not impacted by clumping or restriction of data, except for the complexity of the spatial regression term in the spatial Bayesian model. Methods, such as those made available by R-INLA, can be successfully used to account for spatial autocorrelation in an SDM context and, by taking account of random effects, produce outputs that can better elucidate the role of covariates in predicting species occurrence. Given that it is often unclear what the drivers are behind data clumping in an empirical occurrence dataset, or indeed how geographically restricted these data are, spatially-explicit Bayesian SDMs may be the better choice when modelling the spatial distribution of target species.

AB - A. dorsata builds its large exposed comb high in trees or under ledges of high rocks. The "open" nest of A. dorsata, shielded (only!) by multiple layers of bees, is highly vulnerable to any kind of direct contact or close range attacks from predators. Therefore, guard bees of the outer layer of A. dorsata's nest monitor the vicinity for possible hazards and an effective risk assessment is required. Guard bees, however, are frequently exposed to different objects like leaves, twigs and other tree litter passing the nest from above and falling to the ground. Thus, downward movement of objects past the nest might be used by A. dorsata to classify these visual stimuli near the nest as "harmless". To test the effect of movement direction on defensive responses, we used circular black discs that were moved down or up in front of colonies and recorded the number of guard bees flying towards the disc. The size of the disc (diameter from 8 cm to 50 cm) had an effect on the number of guard bees responding, the bigger the plate the more bees started from the nest. The direction of a disc's movement had a dramatic effect on the attraction. We found a significantly higher number of attacks, when discs were moved upwards compared to downward movements (GLMM (estimate +/- s.e.) 1.872 +/- 0.149, P < 0.001). Our results demonstrate for the first time that the vertical direction of movement of an object can be important for releasing defensive behaviour. Upward movement of dark objects near the colony might be an innate releaser of attack flights. At the same time, downward movement is perceived as a "harmless" stimulus. PMID- 29190295 TI - malERA: An updated research agenda for combination interventions and modelling in malaria elimination and eradication. AB - This paper summarises key advances and priorities since the 2011 presentation of the Malaria Eradication Research Agenda (malERA), with a focus on the combinations of intervention tools and strategies for elimination and their evaluation using modelling approaches. With an increasing number of countries embarking on malaria elimination programmes, national and local decisions to select combinations of tools and deployment strategies directed at malaria elimination must address rapidly changing transmission patterns across diverse geographic areas. However, not all of these approaches can be systematically evaluated in the field. Thus, there is potential for modelling to investigate appropriate 'packages' of combined interventions that include various forms of vector control, case management, surveillance, and population-based approaches for different settings, particularly at lower transmission levels. Modelling can help prioritise which intervention packages should be tested in field studies, suggest which intervention package should be used at a particular level or stratum of transmission intensity, estimate the risk of resurgence when scaling down specific interventions after local transmission is interrupted, and evaluate the risk and impact of parasite drug resistance and vector insecticide resistance. However, modelling intervention package deployment against a heterogeneous transmission background is a challenge. Further validation of malaria models should be pursued through an iterative process, whereby field data collected with the deployment of intervention packages is used to refine models and make them progressively more relevant for assessing and predicting elimination outcomes.

AB - BACKGROUND: Although facial cleanliness is part of the SAFE strategy for trachoma there is controversy over the reliability of measuring a clean face. A child's face with no ocular and nasal discharge is clean and the endpoint of interest, regardless of the number of times it must be washed to achieve that endpoint. The issue of reliability rests on the reproducibility of graders to assess a clean face. We report the reproducibility of assessing a clean face in a field trial in Kongwa, Tanzania. METHODS/FINDINGS: Seven graders were trained to assess the presence and absence of nasal and ocular discharge on children's faces. Sixty children ages 1-7 years were recruited from a community and evaluated independently by seven graders, once and again about 50 minutes later. Intra-and inter-observer variation was calculated using unweighted kappa statistics. The average intra-observer agreement was kappa = 0.72, and the average inter-observer agreement was kappa = 0.78. CONCLUSIONS: Intra-observer and inter-observer agreement was substantial for the assessment of clean faces using trained Tanzania staff who represent a variety of educational backgrounds. As long as training is provided, the estimate of clean faces in children should be reliable, and reflect the effort of families to keep ocular and nasal discharge off the faces. These data suggest assessment of clean faces could be added to trachoma surveys, which already measure environmental improvements, in districts.

AB - Guilt-by-association codifies the empirical observation that a gene's function is informed by its neighborhood in a biological network. This would imply that when a gene's network context is altered, for instance in disease condition, so could be the gene's function. Although context-specific changes in biological networks have been explored, the potential changes they may induce on the functional roles of genes are yet to be characterized. Here we analyze, for the first time, the network-induced potential functional changes in breast cancer. Using transcriptomic samples for 1047 breast tumors and 110 healthy breast tissues from TCGA, we derive sample-specific protein interaction networks and assign sample specific functions to genes via a diffusion strategy. Testing for significant changes in the inferred functions between normal and cancer samples, we find several functions to have significantly gained or lost genes in cancer, not due to differential expression of genes known to perform the function, but rather due to changes in the network topology. Our predicted functional changes are supported by mutational and copy number profiles in breast cancers. Our diffusion based functional assignment provides a novel characterization of a tumor that is complementary to the standard approach based on functional annotation alone. Importantly, this characterization is effective in predicting patient survival, as well as in predicting several known histopathological subtypes of breast cancer. PMID- 29190300 TI - malERA: An updated research agenda for malaria elimination and eradication. AB - Achieving a malaria-free world presents exciting scientific challenges as well as overwhelming health, equity, and economic benefits. WHO and countries are setting ambitious goals for reducing the burden and eliminating malaria through the "Global Technical Strategy" and 21 countries are aiming to eliminate malaria by 2020. The commitment to achieve these targets should be celebrated. However, the need for innovation to achieve these goals, sustain elimination, and free the world of malaria is greater than ever. Over 180 experts across multiple disciplines are engaged in the Malaria Eradication Research Agenda (malERA) Refresh process to address problems that need to be solved. The result is a research and development agenda to accelerate malaria elimination and, in the longer term, transform the malaria community's ability to eradicate it globally. PMID- 29190301 TI - Identification and validation of reference genes for gene expression analysis in Aphidius gifuensis (Hymenoptera: Aphidiidae). AB - Reference genes have been utilized in estimating gene expression levels using quantitative reverse transcriptase-quantitative polymerase chain reaction (qRT PCR) analysis. Aphidius gifuensis Ashmaed is one of the most widely used biological control agents for aphids. The biological properties of this species have been studied in detail, and current investigations are focused on elucidating the regulatory mechanisms in its host However, the appropriate reference genes for target gene expression studies have not been identified. In this study, the expression profiles of 12 candidate reference genes were evaluated under different experimental conditions(development stage, sex, tissue type, diet) by using dedicated algorithms, including geNorm, Normfinder, BestKeeper, and DeltaCt. In addition, RefFinder was used to rank the overall stability of the candidate genes. Finally, we recommend three optimal reference genes for the normalization of qRT-PCR data in the presence of specific variables, which include ACTB, RPL13, and PPI for different developmental stages; RPS18, ACTB, and RPL13 for sexes; RPL13, PRII3, and RPS18 in different tissue types; and RPL13, RPL27, and ACTB in diverse diets. The present study has identified optimal reference genes that could be used in estimating the expression levels of specific genes under these conditions following the Minimum Information for publication of Quantitative real-time PCR Experiments (MIQE) guidelines, which would facilitate in advancements in functional genomics research on A. gifuensis. PMID- 29190302 TI - Light from dark: A relictual troglobite reveals a broader ancestral distribution for kimulid harvestmen (Opiliones: Laniatores: Kimulidae) in South America. AB - A new troglobitic harvestman, Relictopiolus galadriel gen. nov et sp. nov., is described from Olhos d'Agua cave, Itacarambi, Minas Gerais State, Brazil. Morphological characters, including male genitalia and exomorphology, suggest that this species belongs to the family Kimulidae, and it appears to share the greatest similarities with Tegipiolus pachypus. Bayesian inference analyses of a molecular dataset strongly support the inclusion of this species in Kimulidae and confirm the hypothesized sister-group relationship between R. galadriel and T. pachypus. A time calibrated phylogeny indicates that these sister-taxa diverged from a common ancestor approximately 40 Mya, during the Paleogene. The current range of Kimulidae illustrates a remarkable disjunct distribution, and leads us to hypothesize that the ancestral distribution of Kimulidae was once much more widespread across eastern Brazil. This may be attributed to the Eocene radiation associated with the warming (and humidifying) events in the Cenozoic when the best conditions for evergreen tropical vegetation in South America were established and followed by the extinction of kimulid epigean populations together with the retraction of rain forests during the Oligocene to Miocene cooling. The discovery of this relictual troglobite indicates that the Olhos d'Agua cave was a stable refugium for this ancient lineage of kimulids and acted as a "museum" of biodiversity. Our findings, considered collectively with the diverse troglofauna of the Olhos d'Agua cave, highlight it as one of the most important hotspots of troglobite diversity and endemism in the Neotropics. Given the ecological stresses on this habitat, the cavernicolous fauna are at risk of extinction and we emphasize the urgent need for appropriate conservation actions. Finally, we propose the transfer of Acanthominua, Euminua, Euminuoides and Pseudominua from Kimulidae to Zalmoxidae, resulting in two new synonymies and 13 new combinations.

In Reference to: "Standardized Attending Rounds to Improve the Patient Experience: A Pragmatic Cluster Randomized Controlled Trial". AB - We read the article by Monash et al. published in the March 2017 issue with great interest.

AB - We thank Talrai et al. for their comments in response to our randomized controlled trial evaluating the impact of standardized rounds on patient, attending, and trainee satisfaction. We agree that many factors beyond rounding structure contribute to resident satisfaction, including those highlighted by the authors, and would enthusiastically welcome additional research in this realm. PMID- 29190312 TI - Cognitive and Neuropsychiatric Correlates of Functional Impairment Across the Continuum of No Cognitive Impairment to Dementia. AB - Objective: The ability to carry out instrumental activities (IADL) of daily living allows older adults to continue to live independently. Previous research suggested IADL were supported by multiple cognitive and neuropsychiatric factors. The primary goal of this study was to investigate whether immediate memory, executive functions, depression, and apathy, predicted unique variance in IADL over and above demographic variables (age and education) and general cognitive screening (Mini-Mental State Exam). Method: Participants (N = 403) were recruited from the Rural and Remote Memory Clinic (75 no cognitive impairment; 75 mild cognitive impairment; 139 dementia due to Alzheimer's disease; 114 non Alzheimer's dementia). Results: Results of hierarchical regression analyses suggested immediate memory, executive functions, apathy, and depression each accounted for unique variance in IADL in the overall sample, but as a predictor only apathy predicted variance in IADLs above demographics and general cognitive status. Further analysis of the diagnostic subgroups suggested different variables were more strongly associated with IADL from group to group (apathy and depression for normal participants, apathy for MCI participants and for participants with dementia due to AD, but not for those with non-AD dementia). Conclusions: The implications for developing cognitive rehabilitation interventions are discussed, with a recommendation for interventions for symptoms of apathy. PMID- 29190313 TI - TGF-beta signaling in cancer metastasis. AB - The transforming growth factor (TGF)-beta signaling events are well known to control diverse processes and numerous responses, such as cell proliferation, differentiation, apoptosis, and migration. TGF-beta signaling plays context dependent roles in cancer: in pre-malignant cells TGF-beta primarily functions as a tumor suppressor, while in the later stages of cancer TGF-beta signaling promotes invasion and metastasis. Recent studies have also suggested that the cross-talk between TGF-beta signaling and other signaling pathways, such as Hippo, Wnt, EGFR/RAS, and PI3K/AKT pathways, may substantially contribute to our current understanding of TGF-beta signaling and cancer. As a result of the wide ranging effects of TGF-beta, blockade of TGF-beta and its downstream signaling components provides multiple therapeutic opportunities. Therefore, the outlook for anti-TGF-beta signaling therapy for numerous diseases appears bright and will provide valuable information and thinking on the drug molecular design. In this review, we focus on recent insights into the regulation of TGF-beta signaling in cancer metastasis which may contribute to the development of novel cancer targeting therapies. PMID- 29190315 TI - Quantitative single-molecule study of TGF-beta/Smad signaling. AB - TGF-beta/Smad signaling pathway triggers diverse cellular responses among different cell types and environmental conditions. Quantitative analysis of protein-protein interactions involved in TGF-beta/Smad signaling is demanded for understanding the molecular mechanism of this signaling pathway. Live-cell single molecule microcopy with high spatiotemporal resolution is a new tool to monitor key molecular events in a real-time manner. In this review, we mainly presented the recent work on the quantitative characterization of TGF-beta/Smad signaling proteins by single-molecule method, and showed how it enabled us to obtain new insights about this canonical signaling process. PMID- 29190316 TI - Utility of initial induction chemotherapy with 5-fluorouracil, cisplatin, and docetaxel (DCF) for T4 esophageal cancer: a propensity score-matched analysis. AB - Although no consensus is available on the treatment of esophageal squamous cell carcinoma (ESCC) invading adjacent organs (T4), establishing effective induction treatments is crucial to altering an unresectable status and achieving curative resection. Here, we evaluated the efficacy of chemotherapy using 5-fluorouracil, cisplatin, and docetaxel (DCF) as the initial induction treatment for T4 ESCC. Fifty patients without distant metastasis who underwent initial induction chemotherapy using DCF for T4 ESCC were propensity score-matched with 50 patients who underwent radiotherapy concurrent with cisplatin and 5-fluorouracil (CRT). In the DCF group, 24 (48.0%) patients underwent surgery, achieving a 64% clinical response rate compared to 72.0% for induction CRT. CRT was also performed in another 24 (48.0%) patients in the DCF group in whom surgical resection was not indicated. The DCF group had significantly higher overall resectability than the CRT group (78.0% vs. 48.0%, P = 0.0017). The esophageal perforation rate during induction treatments was significantly lower in the DCF group than the CRT group (4.0% vs. 18.0%, P = 0.0205). Prognosis was significantly better in the DCF group than the CRT group (5-year cancer-specific survival 42.1% vs. 22.2%, P = 0.0146). Thus, induction DCF chemotherapy in patients with T4 ESCC reduced esophageal perforation and increased overall resectability, leading to better survival than CRT alone. Therefore, DCF chemotherapy may be an effective and safe option for initial induction treatment of T4 ESCC. PMID- 29190317 TI - TGF-beta signaling pathway in early mouse development and embryonic stem cells. AB - TGF-beta superfamily signaling pathways essentially contribute to the broad spectrum of early developmental events including embryonic patterning, cell fate determination and dynamic movements. In this review, we first introduced some key developmental processes that require TGF-beta signaling to show the fundamental importance of these pathways. Then we discuss how their activities are regulated, and new findings about how the TGF-beta superfamily ligands bind to the chromatin to regulate transcription during embryo development. PMID- 29190314 TI - The role of TGF-beta superfamily signaling in neurological disorders. AB - The TGF-beta superfamily signaling is involved in a variety of biological processes during embryogenesis and in adult tissue homeostasis. Faulty regulation of the signaling pathway that transduces the TGF-beta superfamily signals accordingly leads to a number of ailments, such as cancer and cardiovascular, metabolic, urinary, intestinal, skeletal, and immune diseases. In recent years, a number of studies have elucidated the essential roles of TGF-betas and BMPs during neuronal development in the maintenance of appropriate innervation and neuronal activity. The new advancement implicates significant roles of the aberrant TGF-beta superfamily signaling in the pathogenesis of neurological disorders. In this review, we compile a number of reports implicating the deregulation of TGF-beta/BMP signaling pathways in the pathogenesis of cognitive and neurodegenerative disorders in animal models and patients. We apologize in advance that the review falls short of providing details of the role of TGF beta/BMP signaling or mechanisms underlying the pathogenesis of neurological disorders. The goal of this article is to reveal a gap in our knowledge regarding the association between TGF-beta/BMP signaling pathways and neuronal tissue homeostasis and development and facilitate the research with a potential to develop new therapies for neurological ailments by modulating the pathways. PMID- 29190318 TI - Crosstalk between TGF-beta signaling and epigenome. AB - The transforming growth factor beta (TGF-beta) family of ligands plays major roles in embryonic development, tissue homeostasis, adult immunity, and wound repair. Dysregulation of TGF-beta signaling pathway leads to severe diseases. Its key components have been revealed over the past two decades. This family of cytokines acts by activating receptor activated SMAD (R-SMAD) transcription factors, which in turn modulate the expression of specific sets of target genes. Cells of a multicellular organism have the same genetic information, yet they show structural and functional differences owing to differential expression of their genes. Studies have demonstrated that epigenetic regulation, an integral part of the TGF-beta signaling, enables cells to sense and respond to TGF-beta signaling in a cell context-dependent manner. R-SMAD, as the central transcription factor of TGF-beta signaling, can recruit various epigenetic regulators to shape the transcriptome. In this review, we focus on epigenetic regulatory mechanisms in the TGF-beta signaling during mammalian development and diseases and discuss the central role of the interaction between R-SMAD and various epigenetic regulators in this epigenetic regulation. The crosstalk between TGF-beta signaling and the epigenome could serve as a versatile fine tuning mechanism for transcriptional regulation during embryonic development and progression of diseases, particularly cancer. PMID- 29190321 TI - Hypochlorous Acid Versus Povidone-Iodine Containing Irrigants: Which Antiseptic is More Effective for Breast Implant Pocket Irrigation? AB - Background: Capsular contracture induced by chronic subclinical infection is a major cause of poor outcomes and reoperation in breast implant surgery. The use of pocket irrigation with antiseptic/antibiotic has been shown to reduce the incidence of contracture. A new formulation of hypochlorous acid solution PhaseOne has been proposed as potential agent for irrigation. Objectives: This study aimed to test the efficacy of hypochlorous acid solution PhaseOne for use in breast pocket irrigation as an alternative to povidone iodine solution Betadine. Methods: The efficacy of PhaseOne, a hypochlorous acid formulated wound and skin cleanser, was tested in vitro against planktonic and biofilm Staphylococcus aureus with or without biological soil and in an implant attachment assay. Its activity was compared with Betadine containing 10% povidone iodine. Results: Our findings showed that PhaseOne was unable to eradicate planktonic and/or biofilm S. aureus in the presence of either tryptone soy broth or bovine calf serum (protein soil) in a variety of in vitro assays. Conclusions: We advise that povidone iodine containing irrigants are superior to hypochlorous acid containing irrigants in the clinical setting and should remain the recommended solution for pocket irrigation to reduce bacterial contamination at breast implants surgery. PMID- 29190320 TI - Comparing the Outcomes of Adults With Enterobacteriaceae Bacteremia Receiving Short-Course Versus Prolonged-Course Antibiotic Therapy in a Multicenter, Propensity Score-Matched Cohort. AB - Background: The recommended duration of antibiotic treatment for Enterobacteriaceae bloodstream infections is 7-14 days. We compared the outcomes of patients receiving short-course (6-10 days) vs prolonged-course (11-16 days) antibiotic therapy for Enterobacteriaceae bacteremia. Methods: A retrospective cohort study was conducted at 3 medical centers and included patients with monomicrobial Enterobacteriaceae bacteremia treated with in vitro active therapy in the range of 6-16 days between 2008 and 2014. 1:1 nearest neighbor propensity score matching without replacement was performed prior to regression analysis to estimate the risk of all-cause mortality within 30 days after the end of antibiotic treatment comparing patients in the 2 treatment groups. Secondary outcomes included recurrent bloodstream infections, Clostridium difficile infections (CDI), and the emergence of multidrug-resistant gram-negative (MDRGN) bacteria, all within 30 days after the end of antibiotic therapy. Results: There were 385 well-balanced matched pairs. The median duration of therapy in the short course group and prolonged-course group was 8 days (interquartile range [IQR], 7 9 days) and 15 days (IQR, 13-15 days), respectively. No difference in mortality between the treatment groups was observed (adjusted hazard ratio [aHR], 1.00; 95% confidence interval [CI], .62-1.63). The odds of recurrent bloodstream infections and CDI were also similar. There was a trend toward a protective effect of short course antibiotic therapy on the emergence of MDRGN bacteria (odds ratio, 0.59; 95% CI, .32-1.09; P = .09). Conclusions: Short courses of antibiotic therapy yield similar clinical outcomes as prolonged courses of antibiotic therapy for Enterobacteriaceae bacteremia, and may protect against subsequent MDRGN bacteria. PMID- 29190319 TI - Clinical consequences of upfront pathology review in the randomised PORTEC-3 trial for high-risk endometrial cancer. AB - Background: In the PORTEC-3 trial, women with high-risk endometrial cancer (HR EC) were randomised to receive pelvic radiotherapy (RT) with or without concurrent and adjuvant chemotherapy (two cycles of cisplatin 50 mg/m2 in weeks 1 and 4 of RT, followed by four cycles of carboplatin AUC5 and paclitaxel 175 mg/m2). Pathology review was required before patient enrolment. The aim of this analysis was to evaluate the role of central pathology review before randomisation. Patients and methods: A total of 1295 cases underwent pathology review to confirm HR-EC in the Netherlands (n = 395) and the UK (n = 900), and for 1226/1295 (95%) matching review and original reports were available. In total, 329 of these patients were enrolled in the PORTEC-3 trial: 145 in the Netherlands and 184 in the UK, comprising 48% of the total PORTEC-3 cohort of 686 participants. Areas of discrepancies were evaluated, and inter-observer agreement between original and review opinion was evaluated by calculating the kappa value (kappa). Results: In the 1226 pathology reviews, 6356 selected items were evaluable for both original and review pathology. In 43% of cases at least one pathology item changed after review. For 102 patients (8%), this discrepancy led to ineligibility for the PORTEC-3 trial, most frequently due to differences in the assessment of histological type (34%), endocervical stromal involvement (27%) and histological grade (19%). Lowest inter-observer agreement was found for histological type (kappa = 0.72), lymph-vascular space invasion (kappa = 0.72) and histological grade (kappa = 0.70). Conclusion: Central pathology review by expert gynaeco-pathologists changed histological type, grade or other items in 43% of women with HR-EC, leading to ineligibility for the PORTEC-3 trial in 8%. Upfront pathology review is essential to ensure enrolment of the target trial population, and to avoid over- or undertreatment, especially when treatment modalities with substantial toxicity are involved. This study is registered with ISRCTN (ISRCTN14387080, www.controlled-trials.com) and with ClinicalTrials.gov (NCT00411138).

AB - Background: Systemic anticancer therapy (SACT) is a collective term to describe the growing number of differing therapies used in malignancy to achieve palliation. Improving symptoms, quality of life (QOL) and where possible quantity of life are the goals of these treatments. Sources of data: A comprehensive literature review was undertaken using Medline, Embase and the Cochrane database. Areas of agreement: The use of palliative SACT can lead to increases in symptom control, QOL and survival. The breadth of treatable cancers has increased along with the number of therapeutic options. Areas of controversy: The increasing use of SACT in the last weeks of life and the lack of consistency about the terms Supportive Care/Best Supportive Care in the trial setting. Growing points: Integration between oncology and other palliative services leads to better outcomes. Areas timely for developing research: Improved prognostication tools to elucidate which patients will benefit from SACT.

AB - Enantioseparation of substituted 1,3-diazaspiro[4.5]decan-4-ones (1-14) was achieved using different polysaccharide type chiral stationary phases (CSPs), namely, Chiralcel OJ, Chiralcel OD and Lux-Amylose-2 using different mobile phases which were either n-hexane/2-propanol or n-hexane/ethanol mixtures of various ratios (v/v) at flow rate 1 mL min-1. UV detection was carried out at 254 nm and temperature of 20 degrees C. The retention behavior and selectivity of these CSPs were examined in isocratic normal phase high-performance liquid chromatography mode. The results revealed that the amylose CSP (Lux-Amylose-2) could separate almost all the compounds under investigation in contrast to cellulose CSPs (Chiracel OJ and Chiracel OD) which resolved fewer compounds. PMID- 29190325 TI - Joint Analysis of Cortical Area and Thickness as a Replacement for the Analysis of the Volume of the Cerebral Cortex. AB - Cortical surface area is an increasingly used brain morphology metric that is ontogenetically and phylogenetically distinct from cortical thickness and offers a separate index of neurodevelopment and disease. However, the various existing methods for assessment of cortical surface area from magnetic resonance images have never been systematically compared. We show that the surface area method implemented in FreeSurfer corresponds closely to the exact, but computationally more demanding, mass-conservative (pycnophylactic) method, provided that images are smoothed. Thus, the data produced by this method can be interpreted as estimates of cortical surface area, as opposed to areal expansion. In addition, focusing on the joint analysis of thickness and area, we compare an improved, analytic method for measuring cortical volume to a permutation-based nonparametric combination (NPC) method. We use the methods to analyze area, thickness and volume in young adults born preterm with very low birth weight, and show that NPC analysis is a more sensitive option for studying joint effects on area and thickness, giving equal weight to variation in both of these 2 morphological features. PMID- 29190326 TI - Major Feedforward Thalamic Input Into Layer 4C of Primary Visual Cortex in Primate. AB - One of the underlying principles of how mammalian circuits are constructed is the relative influence of feedforward to recurrent synaptic drive. It has been dogma in sensory systems that the thalamic feedforward input is relatively weak and that there is a large amplification of the input signal by recurrent feedback. Here we show that in trichromatic primates there is a major feedforward input to layer 4C of primary visual cortex. Using a combination of 3D-electron-microscopy and 3D-confocal imaging of thalamic boutons we found that the average feedforward contribution was about 20% of the total excitatory input in the parvocellular (P) pathway, about 3 times the currently accepted values for primates. In the magnocellular (M) pathway it was around 15%, nearly twice the currently accepted values. New methods showed the total synaptic and cell densities were as much as 150% of currently accepted values. The new estimates of contributions of feedforward synaptic inputs into visual cortex call for a major revision of the design of the canonical cortical circuit. PMID- 29190327 TI - Control of healthcare- and community-associated MRSA: recent progress and persisting challenges. AB - Background: Healthcare adapted meticillin-resistant Staphylococcus aureus (MRSA) has spread to hospitals around the world over 50 years. More recently, other strains of MRSA have emerged with the ability to spread in the community and infect otherwise healthy individuals. Morbidity and mortality associated with MRSA remains high and its control in both the healthcare and community setting has proven challenging. Sources of data: Pubmed (Medline). Areas of agreement: The use of targeted screening and decolonization, hand hygiene and antimicrobial stewardship is supported by the most robust studies, though many studies have implemented bundles for effective healthcare-associated (HA)-MRSA control. Areas of contention: Universal screening, universal decolonization and contact precautions for HA-MRSA control are supported by less evidence. Some interventions may not be cost-effective. Contact precautions may be associated with potential for patient harm. Evidence for effective control community acquired (CA)-MRSA is largely lacking. Growing points: Programmes that focus on implementing bundles of interventions aimed at targeting HA-MRSA are more likely to be effective, with an emphasis on hand hygiene as a key component. Control of CA-MRSA is likely to be more difficult to achieve and relies on prevalence, risk factors and community healthcare interactions on a broader scale. Areas timely for developing research: Further research in the area of CA-MRSA in particular is required. Antimicrobial stewardship for both CA and HA-MRSA is promising, as is the role of whole genome sequencing in characterizing transmission. However, further work is required to assess their long-term roles in controlling MRSA. With many institutions applying widespread use of chlorhexidine washes, monitoring for chlorhexidine resistance is paramount to sustaining efforts at controlling MRSA. PMID- 29190329 TI - Cortical Phase-Amplitude Coupling in a Progressive Model of Parkinsonism in Nonhuman Primates. AB - Parkinson's disease is associated with abnormal oscillatory electrical activities of neurons and neuronal ensembles throughout the basal ganglia-thalamocortical network. It has recently been documented in patients with advanced parkinsonism that the amplitude of gamma-band oscillations (50-200 Hz) in electrocorticogram recordings from the primary motor cortex is abnormally coupled to the phase of beta band oscillations within the same signals. It is not known when in the course of the disease the abnormal phase-amplitude coupling (PAC) arises, and whether it is influenced by arousal or prior exposure to dopaminergic medications. To address these issues, we analyzed the relationship between the severity of parkinsonian motor signs and the extent of PAC in a progressive model of parkinsonism, using primates that were not exposed to levodopa prior to testing. PAC was measured in electrocorticogram signals from the primary motor cortex and the supplementary motor area in 3 monkeys that underwent weekly injections of small doses of the neurotoxin 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine, rendering them progressively parkinsonian. We found that parkinsonism was associated with increased coupling between the phase of low frequency (4-10 Hz) oscillations and the amplitude of oscillations in the high gamma band (50-150 Hz). These changes only reached significance when the animals became fully parkinsonian. The increased PAC was normalized after levodopa treatment. We also found a similar increase in PAC during sleep, even in normal animals. The identified PAC was independent of concomitant changes in spectral power in the 2.9-9.8Hz or 49.8-150.4 Hz ranges. We conclude that PAC is predominately a sign of advanced parkinsonism, and is, thus, not essential for the development of parkinsonism. However, increased PAC appears to correlate with the severity of fully developed parkinsonism. PMID- 29190328 TI - The Computational Anatomy of Visual Neglect. AB - Visual neglect is a debilitating neuropsychological phenomenon that has many clinical implications and-in cognitive neuroscience-offers an important lesion deficit model. In this article, we describe a computational model of visual neglect based upon active inference. Our objective is to establish a computational and neurophysiological process theory that can be used to disambiguate among the various causes of this important syndrome; namely, a computational neuropsychology of visual neglect. We introduce a Bayes optimal model based upon Markov decision processes that reproduces the visual searches induced by the line cancellation task (used to characterize visual neglect at the bedside). We then consider 3 distinct ways in which the model could be lesioned to reproduce neuropsychological (visual search) deficits. Crucially, these 3 levels of pathology map nicely onto the neuroanatomy of saccadic eye movements and the systems implicated in visual neglect. PMID- 29190330 TI - Human Cortical Thickness Organized into Genetically-determined Communities across Spatial Resolutions. AB - The cerebral cortex may be organized into anatomical genetic modules, communities of brain regions with shared genetic influences via pleiotropy. Such modules could represent novel phenotypes amenable to large-scale gene discovery. This modular structure was investigated with network analysis of in vivo MRI of extended pedigrees, revealing a "multiscale" structure where smaller and larger modules exist simultaneously and in partially overlapping fashion across spatial scales, in contrast to prior work suggesting a specific number of cortical thickness modules. Inter-regional genetic correlations, gene co-expression patterns and computational models indicate that two simple organizational principles account for a large proportion of the apparent complexity in the network of genetic correlations. First, regions are strongly genetically correlated with their homologs in the opposite cerebral hemisphere. Second, regions are strongly genetically correlated with nearby regions in the same hemisphere, with an initial steep decrease in genetic correlation with anatomical distance, followed by a more gradual decline. Understanding underlying organizational principles of genetic influence is a critical step towards a mechanistic model of how specific genes influence brain anatomy and mediate neuropsychiatric risk.

AB - Level of Evidence 5: PMID- 29190332 TI - The Neural Correlates of Intelligence Comparison. AB - Social comparison plays an important role in our daily life. Several studies have investigated the neural mechanism of social comparison; however, their conclusions remain controversial. The present study explored the neural correlates of intelligence comparison and nonsocial size comparison using functional magnetic resonance imaging and a distance effect paradigm. We found that both intelligence and size comparisons obeyed the behavioral distance effect longer response times for near than far distances and this effect involved an overlapping frontal network including the dorsomedial prefrontal cortex and insula. In addition, compared with size comparisons, intelligence comparisons elicited increased activity in the precuneus and angular gyrus, but decreased activity in the inferior parietal lobe. Furthermore, the analysis of seed-based functional connectivity complemented these neural commonalities and differences. Our findings suggest that social and nonsocial comparisons may rely on a common core mechanism, but this mechanism may be supplemented by different domain specific cognitive components. PMID- 29190333 TI - Determination of Sophorabioside in Rat Plasma by UPLC-MS/MS and its Application to a Pharmacokinetic Study. AB - A ultra-performance liquid chromatography tandem mass spectrometry method was initially developed and validated for quantification of sophorabioside in rat plasma using kaempferol-3-O-beta-D-rutinoside as the internal standard (IS). Analyte and IS were preparation through a protein precipitation procedure with 1.0 mL of methanol to a 0.1 mL plasma sample. The processed samples were separated by C18 analytical column using methanol/water containing 0.1% formic acid with gradient elution as the mobile phase at a flow rate of 0.3 mL/min. Sophorabioside (m/z 577.15 -> 269.45) and kaempferol-3-O-beta-D-rutinoside (m/z 593.15 -> 285.84) were detected by a triple quadrupole tandem mass spectrometer in negative electrospray ionization mode using multiple reaction monitoring. The calibration curve for sophorabioside was linear in the range of 6-1,200 ng/mL (r2 > 0.995) with a lower limit of quantification of 6 ng/mL. The inter- and intra day precision and accuracy were well within the acceptable limits. The matrix effects were satisfactory in all of the biological matrices examined. The mean recovery of sophorabioside was always >90%. This method was successfully applied to a pharmacokinetic study of sophorabioside in rats after an oral administration of 90 mg/kg sophorabioside. The main pharmacokinetic parameters: Tmax, Cmax and t1/2 were 6.2 +/- 0.8 h, 1430.83 +/- 183.25 ng/mL, 7.2 +/- 0.5 h, respectively. PMID- 29190334 TI - The Ventral Posterior Lateral Thalamus Preferentially Encodes Externally Applied Versus Active Movement: Implications for Self-Motion Perception. AB - Successful interaction with our environment requires that voluntary behaviors be precisely coordinated with our perception of self-motion. The vestibular sensors in the inner ear detect self-motion and in turn send projections via the vestibular nuclei to multiple cortical areas through 2 principal thalamocortical pathways, 1 anterior and 1 posterior. While the anterior pathway has been extensively studied, the role of the posterior pathway is not well understood. Accordingly, here we recorded responses from individual neurons in the ventral posterior lateral thalamus of macaque monkeys during externally applied (passive) and actively generated self-motion. The sensory responses of neurons that robustly encoded passive rotations and translations were canceled during comparable voluntary movement (~80% reduction). Moreover, when both passive and active self-motion were experienced simultaneously, neurons selectively encoded the detailed time course of the passive component. To examine the mechanism underlying the selective elimination of vestibular sensitivity to active motion, we experimentally controlled correspondence between intended and actual head movement. We found that suppression only occurred if the actual sensory consequences of motion matched the motor-based expectation. Together, our findings demonstrate that the posterior thalamocortical vestibular pathway selectively encodes unexpected motion, thereby providing a neural correlate for ensuring perceptual stability during active versus externally generated motion. PMID- 29190335 TI - Examination of the Construct Validity of the Repeatable Battery for the Assessment of Neuropsychological Status Language Index in a Mixed Neurological Sample. AB - Objective: We sought to examine the construct validity of the Language Index of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Methods: Archival neuropsychological data were collected for 2,057 individuals of diverse neurological etiologies. Results: Correlations were seen between the RBANS Language Index and its indices (Semantic Fluency r = .727; Picture Naming r = .786), between Semantic Fluency and both Category Fluency (r = .379) and the Controlled Oral Word Association test (r = .375), and between Picture Naming and both Visual Naming from the Multilingual Aphasia Examination (r = .447) and the Boston Naming Test (r = .519). Finally, Picture Naming predicted performance on both Visual Naming [F(1,495) = 123.36, p < .000] and the Boston Naming Test [F(1,262) = 96.28, p < .000]. Conclusion: Given these results, support for the interpretation of RBANS Language Index appears warranted in a diverse clinical sample. PMID- 29190336 TI - Slow Waves in Cortical Slices: How Spontaneous Activity is Shaped by Laminar Structure. AB - Cortical slow oscillations (SO) of neural activity spontaneously emerge and propagate during deep sleep and anesthesia and are also expressed in isolated brain slices and cortical slabs. We lack full understanding of how SO integrate the different structural levels underlying local excitability of cell assemblies and their mutual interaction. Here, we focus on ongoing slow waves (SWs) in cortical slices reconstructed from a 16-electrode array designed to probe the neuronal activity at multiple spatial scales. In spite of the variable propagation patterns observed, we reproducibly found a smooth strip of loci leading the SW fronts, overlapping cortical layers 4 and 5, along which Up states were the longest and displayed the highest firing rate. Propagation modes were uncorrelated in time, signaling a memoryless generation of SWs. All these features could be modeled by a multimodular large-scale network of spiking neurons with a specific balance between local and intermodular connectivity. Modules work as relaxation oscillators with a weakly stable Down state and a peak of local excitability to model layers 4 and 5. These conditions allow for both optimal sensitivity to the network structure and richness of propagation modes, both of which are potential substrates for dynamic flexibility in more general contexts.

PMID- 29190337 TI - Optimizing Research to Speed Up Availability of Pediatric Antiretroviral Drugs and Formulations. AB - Globally 1.8 million children are living with human immunodeficiency virus (HIV), yet only 51% of those eligible actually start treatment. Research and development (R&D) for pediatric antiretrovirals (ARVs) is a lengthy process and lags considerably behind drug development in adults. Providing safe, effective, and well-tolerated drugs for children remains critical to ensuring scale-up globally. We review current approaches to R&D for pediatric ARVs and suggest innovations to enable simplified, faster, and more comprehensive strategies to develop optimal formulations. Several approaches could be adopted, including focusing on a limited number of prioritized formulations and strengthening existing partnerships to ensure that pediatric investigation plans are developed early in the drug development process. Simplified and more efficient mechanisms to undertake R&D need to be put in place, and financing mechanisms must be made more sustainable. Lessons learned from HIV should be shared to support progress in developing pediatric formulations for other diseases, including tuberculosis and viral hepatitis. PMID- 29190341 TI - Oral Health Care Needs of Young Adults Transitioning from Foster Care. AB - Children who have aged out of the foster care system face considerable barriers in accessing oral health care. Although this population of foster care alumni may have Medicaid insurance while they are in care to cover dental care, 39 percent of youths who have aged out of foster care do not have dental insurance. This mixed methods study examines factors that contribute to the oral health care disparities of children who have transitioned from foster care. Multivariate analysis revealed that foster care alumni without dental insurance are 93.5 percent less likely to have their dental needs met than those with dental insurance. Themes from the qualitative data indicated a lack of oral health care, quality-of-life issues, and lack of support to access ongoing dental care. Most state Medicaid programs do not provide comprehensive dental care for adults past the age of 20, contributing to oral health disparities among this population. The addition of oral health care coverage under the Patient Protection and Affordable Health Care Act of 2010 for foster care alumni would greatly enhance their quality of life. The article concludes with a discussion of the implications for the role of social workers in promoting oral health care for foster care youths. PMID- 29190340 TI - Continuous Glucose Monitoring for Hypoglycemia Avoidance and Glucose Counterregulation in Long-Standing Type 1 Diabetes. AB - Context: Patients with long-standing type 1 diabetes (T1D) are at increased risk for severe hypoglycemia because of defects in glucose counterregulation and recognition of hypoglycemia symptoms, in part mediated through exposure to hypoglycemia. Objective: To determine whether implementation of real-time continuous glucose monitoring (CGM) as a strategy for hypoglycemia avoidance could improve glucose counterregulation in patients with long-standing T1D and hypoglycemia unawareness. Design, Setting, Participants, and Intervention: Eleven patients with T1D disease duration of ~31 years were studied longitudinally in the Clinical & Translational Research Center of the University of Pennsylvania before and 6 and 18 months after initiation of CGM and were compared with 12 nondiabetic control participants. Main Outcome Measure: Endogenous glucose production response derived from paired hyperinsulinemic stepped-hypoglycemic and euglycemic clamps with infusion of 6,6-2H2-glucose. Results: In patients with T1D, hypoglycemia awareness (Clarke score) and severity (HYPO score and severe events) improved (P < 0.01 for all) without change in hemoglobin A1c (baseline, 7.2% +/- 0.2%). In response to insulin-induced hypoglycemia, endogenous glucose production did not change from before to 6 months (0.42 +/- 0.08 vs 0.54 +/- 0.07 mg.kg-1.min-1) but improved after 18 months (0.84 +/- 0.15 mg.kg-1.min-1; P < 0.05 vs before CGM), albeit remaining less than in controls (1.39 +/- 0.11 mg.kg 1.min-1; P <= 0.01 vs all). Conclusions: Real-time CGM can improve awareness and reduce the burden of problematic hypoglycemia in patients with long-standing T1D, but with only modest improvement in the endogenous glucose production response that is required to prevent or correct low blood glucose.

PMID- 29190344 TI - Response of Maize Hybrids With and Without Rootworm- and Drought-Tolerance to Rootworm Infestation Under Well-Watered and Drought Conditions. AB - Anecdotal data in the past have suggested that the effect of the western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), on maize yield is greater under drought and the effect of drought is greater under rootworm infestations, but no field experiments have controlled both moisture and rootworm levels. Field studies were conducted in 2012, 2013, and 2014 with treatments in a factorial arrangement of western corn rootworm infestation levels, and maize hybrids (with and without tolerance to drought and rootworm feeding). The experiment was repeated under well-watered and drought conditions in adjacent plots. Leaf water potential and stomatal conductance data suggested significant plant stress was achieved in the drought plots toward the end of the season each year and maize hybrids only played a minor role. In particular, in 2012 and 2013 yield was dramatically lower for the drought experiment than for the well-watered experiment. However, the impacts of rootworm infestation level and maize hybrids on water potential, stomatal conductance, and yield were variable across years and between experiments. In fact, the only year that the main effect of rootworm infestation levels significantly impacted yield was in 2014, when an extremely high infestation level was added and this was only for the well-watered portion of the experiment. Overall, rootworm infestation level played a relatively minor role in maize productivity and it did not appear that soil moisture level influenced that to a large degree.

PMID- 29190346 TI - Broad support for regulating the clinical implementation of future reproductive techniques. AB - STUDY QUESTION: Do gynaecologists, infertile patients and the general public, consider that regulation of the clinical implementation of stem cell-based fertility treatments is required? SUMMARY ANSWER: There is broad support from gynaecologists, patients and the general public for regulating the clinical implementation of future stem cell-based fertility treatments. WHAT IS KNOWN ALREADY: There is debate on the need to regulate the clinical implementation of novel techniques. Regulation may hinder their swift adoption and delay benefits for patients, but may prevent the implementation of ineffective or harmful techniques. Stem cell-based fertility treatments, which involve creating oocytes or spermatozoa by manipulating stem cells, are likely to be implemented in clinical practice in the near future and will probably impact future generations as well as the current one. STUDY DESIGN, SIZE, DURATION: A cross-sectional survey was conducted among gynaecologists working in fertility clinics (n = 179), patients with severe infertility (n = 348) and a representative sample of the general public (n = 1250). The questionnaire was disseminated in the Netherlands in the winter of 2015-2016. PARTICIPANTS/MATERIALS, SETTING, METHODS: The newly developed questionnaire was reviewed by experts and tested among the general public. The questionnaire assessed whether participants wanted each of nine potential negative consequences of the clinical implementation of stem cell-based fertility treatments to be regulated. In addition, the importance of all negative and positive potential consequences, the appropriate regulatory body and its need to consult with advisors from various backgrounds was questioned. MAIN RESULTS AND THE ROLE OF CHANCE: In total, 958 respondents completed the questionnaire (response rate: 54%). A large majority of each participant group (>85%) wanted regulation, for at least one potential negative consequence of the clinical implementation of stem cell-based fertility treatments. The majority of all participant groups wanted regulation for serious health risks for intended parents, serious health risks for children and the disposal of human embryos. Regulation for out-of-pocket costs and the burden of treatment received little support. The majority of gynaecologists and the general public, but not the patients, requested regulation for the risk of minor congenital abnormalities, the success rates and the naturalness of treatments. Nevertheless, the majority of patients did consider the former two potential negative consequences important. The majority of all groups preferred a national bioethics committee as the regulatory body. This committee should consult with advisors from various backgrounds and should consider the broader context of potential consequences of the stem cell-based fertility treatments. LIMITATIONS, REASONS FOR CAUTION: This empirical study focuses on only three stakeholder groups. This study reports on the perspective of the majority and this is not per definition the morally right perspective. The transferability of our findings to other cultures and other techniques remains unclear. WIDER IMPLICATIONS OF THE FINDINGS: A national bioethics committee, consulting with advisors from various backgrounds, should regulate the clinical implementation of future stem cell-based fertility treatments. Whether this broad support for regulation applies to novel techniques from other fields of medicine should be examined.

TRIAL REGISTRATION NUMBER: Not applicable. PMID- 29190348 TI - Computational fluid dynamics study of the end-side and sequential coronary artery bypass anastomoses in a native coronary occlusion model. AB - OBJECTIVES: The objective of this study was to evaluate the haemodynamic patterns in each anastomosis fashion using a computational fluid dynamic study in a native coronary occlusion model. METHODS: Fluid dynamic computations were carried out with ANSYS CFX (ANSYS Inc., Canonsburg, PA, USA) software. The incision lengths for parallel and diamond anastomoses were fixed at 2 mm. Native vessels were set to be totally occluded. The diameter of both the native and graft vessels was set to be 2 mm. The inlet boundary condition was set by a sample of the transient time flow measurement which was measured intraoperatively. RESULTS: The diamond anastomosis was observed to reduce flow to the native outlet and increase flow to the bypass outlet; the opposite was observed in the parallel anastomosis. Total energy efficiency was higher in the diamond anastomosis than the parallel anastomosis. Wall shear stress was higher in the diamond anastomosis than in the parallel anastomosis; it was the highest at the top of the outlet. A high oscillatory shear index was observed at the bypass inlet in the parallel anastomosis and at the native inlet in the diamond anastomosis. CONCLUSIONS: The diamond sequential anastomosis would be an effective option for multiple sequential bypasses because of the better flow to the bypass outlet than with the parallel anastomosis. However, flow competition should be kept in mind while using the diamond anastomosis for moderately stenotic vessels because of worsened flow to the native outlet. Care should be taken to ensure that the fluid dynamics patterns are optimal and prevent future native and bypass vessel disease progression. PMID- 29190347 TI - ECIL guidelines for the prevention, diagnosis and treatment of BK polyomavirus associated haemorrhagic cystitis in haematopoietic stem cell transplant recipients. AB - Objectives: To define guidelines for BK polyomavirus (BKPyV)-associated haemorrhagic cystitis (BKPyV-HC) after paediatric and adult HSCT. Methods: Review of English literature and evidence-based recommendations by expert consensus. Results: BKPyV-HC occurs in 8%-25% of paediatric and 7%-54% of adult recipients undergoing allogeneic HSCT. Diagnosis requires the triad of cystitis, macro haematuria and high urine BKPyV loads >7 log10 copies/mL, and exclusion of other relevant aetiologies. BKPyV viraemia is frequent and may serve as a more specific semiquantitative follow-up marker. No randomized controlled trials are available to inform antiviral prophylaxis or treatment. However, hyper-hydration and/or bladder irrigation showed limited prophylactic value. Fluoroquinolones are not effective for prophylaxis or treatment, but rather increase antibiotic resistance. Hyperbaric oxygen or fibrin glue is marginally effective based on small case series from correspondingly equipped centres. Although cidofovir has been reported to improve and/or reduce BKPyV viraemia or viruria, the current data do not support its regular use. Conclusions: BKPyV-HC remains a disabling unmet clinical need in HSCT that requires novel approaches supported by proper clinical trials. PMID- 29190351 TI - The associations of thiopurines with male fertility and paternally exposed offspring: a systematic review and meta-analysis. AB - BACKGROUND: Thiopurines are widely used immunosuppressive agents. In high dosages, they inhibit the purine synthesis and are considered to be possibly harmful to spermatogenesis, and subsequently to men's fertility and their offspring. However, the clear association between thiopurine exposure and male fertility and reproduction safety, if any, is still poorly understood. OBJECTIVE AND RATIONALE: The aim of this review was to systematically summarize and meta analyse the available data, derived from animal and human studies, regarding the influence of thiopurine exposure on fertility and conception safety in men and their offspring. SEARCH METHODS: A systematic literature search of the MEDLINE and EMBASE databases was performed using a combination of relevant terms related to 'thiopurines', 'fertility', 'conception', 'reproduction', 'semen quality' and 'birth outcome', combined with 'male', 'men', 'father' and 'paternal'. The search was not restricted exclusively to human subjects, neither to a type of disease or condition, to gather all available studies with regards to this topic. All published articles on thiopurines and male fertility, written in English and published until May 2017, were screened for eligibility. The GRADE guidelines were used to assess the quality of evidence of the included articles. OUTCOMES: A total of 28 studies (including 14 observational studies in humans) were included in this review and six of these were included in the meta-analysis. In various rodents, thiopurines adversely affected the germ cells (in administered doses of 2 to 20 times the human equivalent dose). In human studies, thiopurine therapy was not evidently associated with impaired testicular function or semen quality in 83 men with a variety of underlying diseases. In total, 53 out of 975 offspring with congenital anomalies (5.4%, the background prevalence is 3%), possibly as a result of paternal thiopurine exposure, were described in all studies together. The risk of congenital anomalies was not significantly increased when compared with offspring without paternal thiopurine exposure (4.7%) (pooled odds ratio 1.32, 95% confidence interval 0.75, 2.34). WIDER IMPLICATIONS: Thiopurines have spermatotoxic effects in rodents. In humans, overall data are limited and derived from underpowered studies, and therefore not conclusive with regards to the possible effects of thiopurines on spermatogenesis or paternally exposed offspring. Larger, epidemiological trials evaluating the safety of thiopurines to men's fertility and their offspring are mandatory to adequately counsel thiopurine treated men who wish to conceive. PMID- 29190350 TI - Psychometric analysis of the TRANSIT quality indicators for cardiovascular disease prevention in primary care. AB - Objective: To assess a selection of psychometric properties of the TRANSIT indicators. Design: Using medical records, indicators were documented retrospectively during the 14 months preceding the end of the TRANSIT study. Setting: Primary care in Quebec, Canada. Participants: Indicators were documented in a random subsample (n = 123 patients) of the TRANSIT study population (n = 759). Interventions: For every patient, the mean compliance to all indicators of a category (subscale score) and to the complete set of indicators (overall scale score) were established. To evaluate test-retest and inter-rater reliabilities, indicators were applied twice, two months apart, by the same evaluator and independently by different evaluators, respectively. To evaluate convergent validity, correlations between TRANSIT indicators, Burge et al. indicators and Institut national d'excellence en sante et en services sociaux (INESSS) indicators were examined. Main Outcome Measures: Test-retest reliability, inter rater reliability, and convergent validity. Results: Test-retest reliability, as measured by intraclass correlation coefficients (ICCs) was equal to 0.99 (0.99 0.99) for the overall scale score while inter-rater reliability was equal to 0.95 (0.93-0.97) for the overall scale score. Convergent validity, as measured by Pearson's correlation coefficients, was equal to 0.77 (P < 0.001) for the overall scale score when the TRANSIT indicators were compared to Burge et al. indicators and to 0.82 (P < 0.001) for the overall scale score when the TRANSIT indicators were compared to INESSS indicators. Conclusions: Reliability was excellent except for eleven indicators while convergent validity was strong except for domains related to the management of CVD risk factors.

AB - Bacillus circulans Jordan 32352 was isolated from decaying organic matter in the New Jersey soil in the early 1930s. This soil-dwelling bacterium produced an enzyme capable of degrading the type 3 capsular polysaccharide (Pn3P) of Streptococcus pneumoniae (Spn). Early reports of this enzyme, Pn3Pase, demonstrated its inducibility by, and specificity for Pn3P. We set out to identify and clone this enzyme for its recombinant expression and characterization. We first sequenced the genome of this bacterial species, and reclassified the Pn3Pase producing bacterium as Paenibacillus species 32352. We identified the putative protein of Pn3Pase through mass spectrometry-based proteomics and cloned the gene for recombinant expression. We then characterized the oligosaccharide products generated upon the enzymatic depolymerization of Pn3P. Sequence analysis suggests that this glycoside hydrolase belongs to a new carbohydrate-active enzyme GH family. To our knowledge, this is the only enzyme to demonstrate Pn3P depolymerization activity.

AB - Background: The therapeutic strategies and prognostic risk factors in patients with lymph node (LN) recurrence of esophageal cancer remain controversial. We assessed clinical outcomes and prognostic factors related to the use of chemoradiotherapy (CRT) for LN recurrence of esophageal squamous cell carcinoma (ESCC) after curative resection. Methods: We retrospectively evaluated survival and prognostic factors in 57 patients with LN recurrence of ESCC after curative resection. Patients received CRT using 5-fluorouracil plus cisplatin (FP) or docetaxel. Radiotherapy was delivered at 2 Gy (total dose, 60-66 Gy; median, 60 Gy). Results: The median follow-up duration was 24 (range, 3-116) months. The overall survival (OS) rates at 2, 3 and 5 years were 43.7%, 36.9% and 27.6%, respectively. In the univariate analysis of OS, treatment with FP, a single LN recurrence, and a single regional recurrence were associated with a significantly better prognosis (P = 0.04, P = 0.027 and P = 0.0001, respectively). In the multivariate analysis, the combination chemotherapy regimen [hazard ratio (HR), 2.50; 95% confidence interval (CI), 1.23-5.07] and the number of the regional LNs with recurrence (HR, 5.76; 95% CI, 1.22-27.12) were independent prognostic factors. Conclusion: Approximately 28% of ESCC patients with LN recurrence after curative resection could achieve long-term survival with CRT. Treatment with FP or patients with a single regional recurrence might improve the treatment outcome. PMID- 29190353 TI - Is the scaling relationship between carbohydrate storage and leaf biomass in meadow plants affected by the disturbance regime? AB - Background and Aims: Below-ground carbohydrate storage is considered an adaptation of plants aimed at regeneration after disturbance. A theoretical model by Iwasa and Kubo was empirically tested which predicted (1) that storage of carbohydrates scales allometrically with leaf biomass and (2) when the disturbance regime is relaxed, the ratio of storage to leaf biomass increases, as carbohydrates are not depleted by disturbance. Methods: These ideas were tested on nine herbaceous species from a temperate meadow and the disturbance regime was manipulated to create recently abandoned and mown plots. Just before mowing in June and at the end of the season in October, plants with below-ground organs were sampled. The material was used to assess the pool of total non-structural carbohydrates and leaf biomass. Key Results: In half of the cases, a mostly isometric relationship between below-ground carbohydrate storage and leaf biomass in meadow plants was found. The ratio of below-ground carbohydrate storage to leaf biomass did not change when the disturbance regime was less intensive than that for which the plants were adapted. Conclusions: These findings (isometric scaling relationship between below-ground carbohydrate storage and leaf biomass; no effect of a relaxed disturbance regime) imply that storage in herbs is probably governed by factors other than just the disturbance regime applied once in a growing season.

AB - OBJECTIVES: Surgical aortic valve replacement (sAVR) is coming under close scrutiny with the recent upswing in the use of less invasive approaches. The aim of this analysis was to identify current trends in patient selection, procedural characteristics and outcomes after sAVR in Germany. METHODS: We analysed data from 42 776 patients included in the German Aortic Valve Registry who underwent sAVR with and without coronary artery bypass surgery (CABG) between 2011 and 2015. Baseline, procedural and short-term outcome parameters were analysed. RESULTS: Of all registered patients, 26 618 (62.2%) underwent isolated sAVR and 16 158 (37.8%) sAVR + CABG. The median age was 72 years, and the median Society of Thoracic Surgeons Predicted Risk of Mortality (STS PROM) was 2.3%. From 2011 to 2015, there was a decline in STS PROM (2.4-2.2%, P < 0.001) and a decline in risk factors, such as pulmonary hypertension (9.1-3.2%, P < 0.001), occlusive arterial disease (19.6-17.7%, P = 0.003), mitral regurgitation >=2 degrees (10.6 7.6%, P < 0.001) and New York Heart Association Class III/IV (65.3-59.2%, P < 0.001). In-hospital mortality was 2.3%, 1.3% had disabling stroke, 0.4% residual aortic regurgitation >=2 degrees , and the incidence of new-onset pacemaker/implantable cardioverter-defibrillator implantation was 3.9%. There was an increase in the use of biological valves in patients <65 years (50.1-65.7%, P < 0.001), and the proportion of rapid deployment valves increased significantly (1.5-8.4%, P < 0.001) over the investigated time period. CONCLUSIONS: Both isolated sAVR as well as sAVR + CABG resulted in excellent in-hospital outcomes based on >42 000 patients treated between 2011 and 2015. The implementation of alternative treatment strategies has resulted in palpable changes in patient and device selection. PMID- 29190356 TI - Multimodality imaging of a right atrial blood cyst.

AB - Background and Objectives: This study evaluated the effectiveness of a telephone based cognitive-behavioral therapy for family caregivers of people with dementia in existing health care provision structures. Research Design and Methods: Two hundred seventy-three family caregivers of people with dementia were randomly assigned to receive the intervention or usual care. Usual care included unrestricted access to community resources. Intervention group participants received twelve 50-min sessions of individual cognitive-behavioral therapy by trained psychotherapists within 6 months. Symptoms of depression, emotional well being, physical health symptoms, burden of care, coping with the care situation and challenging behavior were assessed after the intervention ended and at a 6 month follow-up. Intention-to-treat analyses using latent change models were applied. Results: Intention-to-treat analyses showed improved emotional well being (gamma = 9.59, p = .001), fewer symptoms of depression (gamma = -0.23, p = .043), fewer physical health symptoms (gamma = -0.25, p = .019), improved coping with the care situation (gamma = 0.25, p = .005) and the behavior of the care recipient (gamma = 0.23, p = .034) compared with usual care. Effects for coping (gamma = 0.28, p = .006 and gamma = 0.39, p < .001, respectively) and emotional well-being (gamma = 7.61, p = .007) were also found at follow-up. Discussion and Implications: The CBT-based telephone intervention increased mental and physical health as well as coping abilities of family caregivers of people with dementia. The intervention can be delivered by qualified CBT therapists after an 8-h training session in existing health care provision structures. PMID- 29190358 TI - Developmental Connectivity and Molecular Phenotypes of Unique Cortical Projection Neurons that Express a Synapse-Associated Receptor Tyrosine Kinase. AB - The complex circuitry and cell-type diversity of the cerebral cortex are required for its high-level functions. The mechanisms underlying the diversification of cortical neurons during prenatal development have received substantial attention, but understanding of neuronal heterogeneity is more limited during later periods of cortical circuit maturation. To address this knowledge gap, connectivity analysis and molecular phenotyping of cortical neuron subtypes that express the developing synapse-enriched MET receptor tyrosine kinase were performed. Experiments used a MetGFP transgenic mouse line, combined with coexpression analysis of class-specific molecular markers and retrograde connectivity mapping. The results reveal that MET is expressed by a minor subset of subcerebral and a larger number of intratelencephalic projection neurons. Remarkably, MET is excluded from most layer 6 corticothalamic neurons. These findings are particularly relevant for understanding the maturation of discrete cortical circuits, given converging evidence that MET influences dendritic elaboration and glutamatergic synapse maturation. The data suggest that classically defined cortical projection classes can be further subdivided based on molecular characteristics that likely influence synaptic maturation and circuit wiring. Additionally, given that MET is classified as a high confidence autism risk gene, the data suggest that projection neuron subpopulations may be differentially vulnerable to disorder-associated genetic variation. PMID- 29190360 TI - Barriers to Transition From Pediatric to Adult Care: A Systematic Review. AB - Objective: Transition research in each disease group is developing in its own "silo." A comprehensive review of barriers to transition within and across chronic illness groups is needed to facilitate information sharing and larger scale efforts to overcome barriers and improve patient care. This study systematically reviews and identifies the barriers to transition from pediatric to adult care across pediatric illness populations. Methods: Medline, CINAHL, PsychINFO, Social Services Abstracts, Web of Science, and the Cochrane library databases were searched. Peer-reviewed English articles presenting original data on barriers to transition to adult care, focused on a specific pediatric chronic illness population, and conducted in the United States were included. Study design, population, and barriers were extracted. Barriers were categorized according to the Socioecological Model of Adolescent/Young Adult Readiness to Transition. Articles were evaluated for study quality. Results: Fifty-seven articles were included. The most common barriers to transition fell within the "Relationships" domain (e.g., difficulties letting go of long-standing relationships with pediatric providers) followed by "Access/Insurance" (e.g., difficulty accessing/finding qualified practitioners, insurance issues), and "Beliefs/Expectations" (e.g., negative beliefs about adult care). Barriers related to "Knowledge" (e.g., limited patient/caregiver knowledge about medication/illness and the transition process) and "Skills/Efficacy" (e.g., lack of self-management skills) were also common. While relationship barriers were commonly reported by all, some barriers varied by transfer status (pre- vs. posttransfer). Conclusions: Each chronic illness group experiences illness specific challenges but certain barriers transcend chronic illness populations. Suggestions to overcome these barriers are provided. PMID- 29190359 TI - DNA terminal structure-mediated enzymatic reaction for ultra-sensitive discrimination of single nucleotide variations in circulating cell-free DNA. AB - Sensitive detection of the single nucleotide variants in cell-free DNA (cfDNA) may provide great opportunity for minimally invasive diagnosis and prognosis of cancer and other related diseases. Here, we demonstrate a facile new strategy for quantitative measurement of cfDNA mutations at low abundance in the cancer patients' plasma samples. The method takes advantage of a novel property of lambda exonuclease which effectively digests a 5'-fluorophore modified dsDNA with a 2-nt overhang structure and sensitively responds to the presence of mismatched base pairs in the duplex. It achieves a limit of detection as low as 0.02% (percentage of the mutant type) for BRAFV600E mutation, NRASQ61R mutation and three types of EGFR mutations (G719S, T790M and L858R). The method enabled identification of BRAFV600E and EGFRL858R mutations in the plasma of different cancer patients within only 3.5 h. Moreover, the terminal structure-dependent reaction greatly simplifies the probe design and reduces the cost, and the assay only requires a regular real-time PCR machine. This new method may serve as a practical tool for quantitative measurement of low-abundance mutations in clinical samples for providing genetic mutation information with prognostic or therapeutic implications. PMID- 29190361 TI - Shaping epigenetic memory via genomic bookmarking. AB - Reconciling the stability of epigenetic patterns with the rapid turnover of histone modifications and their adaptability to external stimuli is an outstanding challenge. Here, we propose a new biophysical mechanism that can establish and maintain robust yet plastic epigenetic domains via genomic bookmarking (GBM). We model chromatin as a recolourable polymer whose segments bear non-permanent histone marks (or colours) which can be modified by 'writer' proteins. The three-dimensional chromatin organisation is mediated by protein bridges, or 'readers', such as Polycomb Repressive Complexes and Transcription Factors. The coupling between readers and writers drives spreading of biochemical marks and sustains the memory of local chromatin states across replication and mitosis. In contrast, GBM-targeted perturbations destabilise the epigenetic patterns. Strikingly, we demonstrate that GBM alone can explain the full distribution of Polycomb marks in a whole Drosophila chromosome. We finally suggest that our model provides a starting point for an understanding of the biophysics of cellular differentiation and reprogramming. PMID- 29190363 TI - Efficient in situ barcode sequencing using padlock probe-based BaristaSeq. AB - Cellular DNA/RNA tags (barcodes) allow for multiplexed cell lineage tracing and neuronal projection mapping with cellular resolution. Conventional approaches to reading out cellular barcodes trade off spatial resolution with throughput. Bulk sequencing achieves high throughput but sacrifices spatial resolution, whereas manual cell picking has low throughput. In situ sequencing could potentially achieve both high spatial resolution and high throughput, but current in situ sequencing techniques are inefficient at reading out cellular barcodes. Here we describe BaristaSeq, an optimization of a targeted, padlock probe-based technique for in situ barcode sequencing compatible with Illumina sequencing chemistry. BaristaSeq results in a five-fold increase in amplification efficiency, with a sequencing accuracy of at least 97%. BaristaSeq could be used for barcode assisted lineage tracing, and to map long-range neuronal projections. PMID- 29190362 TI - A human prefrontal-subthalamic circuit for cognitive control. AB - The subthalamic nucleus is a key site controlling motor function in humans. Deep brain stimulation of the subthalamic nucleus can improve movements in patients with Parkinson's disease; however, for unclear reasons, it can also have cognitive effects. Here, we show that the human subthalamic nucleus is monosynaptically connected with cognitive brain areas such as the prefrontal cortex. Single neurons and field potentials in the subthalamic nucleus are modulated during cognitive processing and are coherent with 4-Hz oscillations in medial prefrontal cortex. These data predict that low-frequency deep brain stimulation may alleviate cognitive deficits in Parkinson's disease patients. In line with this idea, we found that novel 4-Hz deep brain stimulation of the subthalamic nucleus improved cognitive performance. These data support a role for the human hyperdirect pathway in cognitive control, which could have relevance for brain-stimulation therapies aimed at cognitive symptoms of human brain disease.awx300media15660002226001. PMID- 29190364 TI - Development of the MapMe intervention body image scales of known weight status for 4-5 and 10-11 year old children. AB - Background: Parents tend to visually assess children to determine their weight status and typically underestimate child body size. A visual tool may aid parents to more accurately assess child weight status and so support strategies to reduce childhood overweight. Body image scales (BIS) are visual images of people ranging from underweight to overweight but none exist for children based on UK criteria. Our aim was to develop sex- and age-specific BIS for children, based on British growth reference (UK90) criteria. Methods: BIS were developed using 3D surface body scans of children, their associated weight status using UK90 criteria from height and weight measurements, and qualitative work with parents and health professionals. Results: Height, weight and 3D body scans were collected (211: 4-5 years; 177: 10-11 years). Overall, 12 qualitative sessions were held with 37 participants. Four BIS (4-5-year-old girls and boys, 10-11-year-old girls and boys) were developed. Conclusions: This study has created the first sex- and age specific BIS, based on UK90 criteria. The BIS have potential for use in child overweight prevention and management strategies, and in future research. This study also provides a protocol for the development of further BIS appropriate to other age groups and ethnicities. PMID- 29190365 TI - A National Portrait of Stepfamilies in Later Life. AB - Objectives: Scholars have documented increases in the prevalence and complexity of stepfamilies earlier in the life course, but no one has systematically investigated U.S. stepfamily structure in later life. Guided by a family systems approach, we described the prevalence and composition of later-life stepfamilies. Method: The analysis was based on 6,250 married and cohabiting couples participating in the 2012 Health and Retirement Study. We identified the prevalence of later-life stepfamilies, decomposed stepfamily structures, and compared the sociodemographic characteristics and relationship quality of the couples in stepfamilies with those in married families (with only joint children and no stepchildren), paying attention to differences between married and cohabiting stepfamilies. Results: Roughly 40% of middle-aged and older couples with children were in stepfamilies. Of all stepfamilies, 86% were married couples and 14% were cohabiting couples. Cohabiting stepfamilies more often included children from both partners' previous relationships, but couples in married stepfamilies more often had joint children. Cohabiting stepfamilies appeared to be the most socially and economically disadvantaged, followed by married stepfamilies, and lastly married families. Despite these compositional differences, partner relationship quality was largely similar across married families, married stepfamilies, and cohabiting stepfamilies. Discussion: This study underscores the high prevalence and complexity of later-life stepfamilies and foregrounds the urgency of additional research on this topic. PMID- 29190366 TI - Unexpected drought resistance strategies in seedlings of four Brachychiton species. AB - Functional traits associated with drought resistance can be useful for predicting tree responses to a drying climate. Yet drought resistance is likely achieved through a complex combination of constitutive traits (traits expressed even in benign environments) and plastic traits (traits expressed only in response to drought). Because few studies measure multiple traits for multiple species under both well-watered and drought conditions, we often struggle to identify suites of constitutive and plastic traits indicative of drought resistance strategies. Using a greenhouse experiment, we examined nine drought resistance traits (six morphological/allocation traits plus assimilation, stomatal conductance and water use efficiency) in well-watered and water-stressed seedlings of four Brachychiton (Malvaceae Juss.) species with ranges spanning a strong aridity gradient in east central Australia. In benign conditions, constitutive biomass allocation was consistent with expectations, with xeric species investing more heavily in roots and stem tissue and less in leaf tissue than mesic species (P = 0.004). Under drought conditions, xeric species decreased relative biomass allocation below ground while mesic species increased relative below-ground allocation (treatment * species interaction P = 0.0015). Relative water content of the stems was slightly higher in xeric species (P = 0.055), and remained stable during drought while decreasing in mesic species (treatment * species P = 0.001). Specific leaf area (SLA) and leaf dry matter content (LDMC) did not fit with expectations under either benign or water-limited conditions. Moreover, stomatal conductance and carbon assimilation were unexpectedly highest and intrinsic water-use efficiency (WUEi) lowest in the xeric species in benign conditions. Only under drought did the xeric species manifest higher WUEi than the mesic species (treatment * species P < 0.0001). We found that even closely related species exhibited diverse combinations of drought resistance traits. Notably, traits commonly used as proxies for drought tolerance (e.g., SLA, LDMC, well-watered WUEi) performed more poorly than constitutive allocation traits. This study highlights the need to consider multiple traits and phenotypic plasticity when assessing species' drought resistance for forest management in the face of climate change. PMID- 29190367 TI - Early Experience with Bilateral Continuous Femoral Nerve Block and Single Injection Spinal Anesthesia for Bilateral Total Knee Arthroplasty: A Case Series. AB - Objective: Total knee arthroplasty (TKA) is a commonly performed surgery in the United States, with demand for unilateral and simultaneous bilateral TKAs (BTKAs) expected to increase significantly over the coming decades. This study reports the authors' early experience in a consecutive series of simultaneous BTKAs performed under regional anesthesia and mild sedation. Methods: In this retrospective case series, the authors examined all simultaneous BTKAs performed over two years by a single surgeon. Only patients receiving bilateral continuous femoral nerve blockade (CFNB) and single-injection sciatic nerve blockade in combination with single-injection subarachnoid block were included in the study. Of the 32 patients who underwent BTKAs during this period, 25 met the inclusion criteria. The patient's anesthesia records, physician notes, nursing notes, pharmacy records, and physical therapy records were then reviewed systematically to create a database of information. Results: Only one of 25 patients required conversion to general anesthesia during surgery. There were no major perioperative complications. The average Defense and Veterans Pain Rating Scale score immediately postoperation was 0.6/10, and the average daily score remained below 3.5/10 throughout the hospital stay. The use of bilateral CFNB did not prevent patients from ambulating during physiotherapy. Conclusions: This early retrospective case series suggests that it is feasible to effectively manage the postoperative pain associated with BTKA with staged bilateral CFNB and single injection sciatic nerve blockage in combination with single-injection subarachnoid block as the sole anesthetic technique without negatively influencing early ambulation. PMID- 29190368 TI - Interindividual variability in gut microbiota and host response to dietary interventions. AB - Dysbiosis is linked to human disease; therefore, gut microbiota modulation strategies provide an attractive means of correcting microbial imbalance to enhance human health. Because diet has a major influence on the composition, diversity, and metabolic capacity of the gut microbiota, numerous dietary intervention studies have been conducted to manipulate the gut microbiota to improve host outcomes and reduce disease risk. Emerging evidence suggests that interindividual variability in gut microbiota and host responsiveness exists, making it difficult to predict gut microbiota and host response to a given dietary intervention. This may, in turn, have implications on the consistency of results among studies and the perceived success or true efficacy of a dietary intervention in eliciting beneficial changes to the gut microbiota and human health. PMID- 29190369 TI - Decision-Making Preferences and Deprescribing: Perspectives of Older Adults and Companions About Their Medicines. AB - Objectives: Polypharmacy in the older population is increasing-and can be harmful. It can be safe to reduce or carefully cease medicines (deprescribing) but a collaborative approach between patient and doctor is required. This study explores decision-making about polypharmacy with older adults and their companions. Method: Semi-structured interviews were conducted with 30 older people (aged 75+ years, taking multiple medicines) and 15 companions. Framework analysis was used to identify qualitative themes. Results: Participants varied considerably in attitudes towards medicines, preferences for involvement in decision-making, and openness to deprescribing. Three types were identified. Type 1 held positive attitudes towards medicines, and preferred to leave decisions to their doctor. Type 2 voiced ambivalent attitudes towards medicines, preferred a proactive role, and were open to deprescribing. Type 3 were frail, perceived they lacked knowledge about medicines, and deferred most decisions to their doctor or companion. Discussion: This study provides a novel typology to describe differences between older people who are happy to take multiple medicines, and those who are open to deprescribing. To enable shared decision-making, prescribers need to adapt their communication about polypharmacy based on their patients' attitudes to medicines and preferences for involvement in decisions. PMID- 29190370 TI - Best practices for using natural experiments to evaluate retail food and beverage policies and interventions. AB - Policy and programmatic change in the food retail setting, including excise taxes on beverages with added-caloric sweeteners, new supermarkets in food deserts, and voluntary corporate pledges, often require the use of natural experimental evaluation for impact evaluation when randomized controlled trials are not possible. Although natural experimental studies in the food retail setting provide important opportunities to test how nonrandomized interventions affect behavioral and health outcomes, researchers face several key challenges to maintaining strong internal and external validity when conducting these studies. Broadly, these challenges include 1) study design and analysis; 2) selection of participants, selection of measures, and obtainment of data; and 3) real-world considerations. This article addresses these challenges and different approaches to meeting them. Case studies are used to illustrate these approaches and to highlight advantages and disadvantages of each approach. If the trade-offs required to address these challenges are carefully considered, thoughtful natural experimental evaluations can minimize bias and provide critical information about the impacts of food retail interventions to a variety of stakeholders, including the affected population, policymakers, and food retailers. PMID- 29190371 TI - Determination of Cephalosporins by UHPLC-DAD Using Molecularly Imprinted Polymers. AB - Molecularly imprinted polymers (MIPs) were synthesized for the determination of cephalosporins (cephazolin, ceftazidime, cefotaxime, ceftriaxone, cefepime and cephalexin) by ultra-high performance liquid chromatography with diode-array detection (UHPLC-DAD). After optimization, MIPs were synthesized using cephazolin as the template, methacrylic acid as the functional monomer, triethylenglycol dimethacrylate as the crosslinker, acetonitrile/dimethylsulfoxide as porogens and benzoyl peroxide as the radical initiator. Not only this is a novel route of MIP synthesis for cephalosporins, but also this choice of analytes is unique. Chromatographic separation was performed in a C8 column using a binary gradient with trifluoroacetic acid 0.1% in water and acetonitrile. Linearity was assessed up to 100 MUg mL-1 and linear correlation coefficients (r) were all higher than 0.99, limits of detection were within the range of 3-12 ng mL-1, and recoveries from 86 to 102% were obtained for concentrations between 0.05 and 1.0 MUg mL-1. PMID- 29190372 TI - What Can Elder Mistreatment Researchers Learn About Primary Prevention From Family Violence Intervention Models? AB - Elder mistreatment (EM) is a public health problem that harms millions of older Americans each year. Despite growing recognition of its occurrence, there are no evidence-based primary prevention programs. Although EM is distinct from other areas of family violence, including child maltreatment and intimate partner violence, common risk factors and theoretical underpinnings point to opportunities for prevention strategies. Drawing on evidence-based best practices found in other fields of family violence, we identify approaches that could be tested to prevent EM at the hands of family caregivers, who are among the most likely to commit mistreatment. Specifically, we examine home visiting approaches primarily used in the child maltreatment field and identify components that have potential to inform EM interventions, including prevention. We conclude that there is enough information to begin testing a prevention intervention for EM that targets caregivers. PMID- 29190373 TI - Adult and elderly population access to trauma centers: an ecological analysis evaluating the relationship between injury-related mortality and geographic proximity in the United States in 2010. AB - Background: Ongoing development and expansion of trauma centers in the United States necessitates empirical analysis of the effect of investment in such resources on population-level health outcomes. Methods: Multiple linear regressions were performed to predict state-level trauma-related mortality among adults and the elderly across 50 US states in 2010. The number of trauma centers per capita in each state and the percentage of each state's population living within 45-min of a trauma center served as the key independent variables and injury-related mortality served as the dependent variable. All analyses were stratified by age (adult versus elderly; elderly >= 65 years old) and were performed in SPSS. Results: The proportion of a population with geographic proximity to a trauma center demonstrates a consistent inverse linear relationship to injury-related mortality. The relationship reliably retains its significance in models including demographic covariates. Interestingly, access to Levels I and II trauma centers demonstrates a stronger correlation with mortality than was observed with Level III centers. Conclusion: Trauma center access is associated with reduced trauma-related mortality among both adults and the elderly as measured by state reported mortality rates. Ongoing efforts to designate and verify new trauma centers, particularly in poorly-served 'trauma deserts', could lead to lower mortality for large populations. PMID- 29190374 TI - Scaling up newborn care in Afghanistan: opportunities and challenges for the health sector. AB - Newborn health in Afghanistan is receiving increased attention, but reduction in newborn deaths there has not kept pace with declines in maternal and child mortality. Using the continuum of care and health systems building block frameworks, this article identifies, organizes and provides a synthesis of the available evidence on and gaps in coverage of care and health systems, programmes, policies and practices related to newborn health in Afghanistan. Newborn mortality in Afghanistan is related to the nation's weak health system, itself associated with decades of conflict, low and uneven coverage of essential interventions, demand-side and cultural specificities, and compromised quality. A majority of deliveries still take place at home. Birth asphyxia, low birth weight, perinatal infections and poor post-natal care are responsible for many preventable newborn deaths. Though the situation has improved, there remain many opportunities to accelerate progress. Analyses conducted using the Lives Saved Tools suggest that an additional 10 405 newborn lives could be saved in Afghanistan in 5 years (2015-20), through reasonable increases in coverage of these high-impact interventions. A long-term vision and strong leadership are essential for the Ministry of Public Health to play an effective stewardship role in formulating related policy and strategy, setting standards and monitoring maternal and newborn services. Promotion of equitable access to health services, including health workforce planning, development and management, and the coordination of much-needed donor support are also imperative. PMID- 29190375 TI - High-resolution mapping of molecules in an ionic liquid via scanning transmission electron microscopy. AB - Understanding structures and spatial distributions of molecules in liquid phases is crucial for the control of liquid properties and to develop efficient liquid phase processes. Here, real-space mapping of molecular distributions in a liquid was performed. Specifically, the ionic liquid 1-Ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (C2mimTFSI) was imaged using atomic-resolution scanning transmission electron microscopy. Simulations revealed network-like bright regions in the images that were attributed to the TFSI- anion, with minimal contributions from the C2mim+ cation. Simple visualization of the TFSI- distribution in the liquid sample was achieved by binarizing the experimental image. PMID- 29190376 TI - p53 promotes AKT and SP1-dependent metabolism through the pentose phosphate pathway that inhibits apoptosis in response to Nutlin-3a. AB - Nutlin-3a is a MDM2 antagonist and preclinical drug that activates p53. Cells with MDM2 gene amplification are especially prone to Nutlin-3a-induced apoptosis, though the basis for this is unclear. Glucose metabolism can inhibit apoptosis in response to Nutlin-3a through mechanisms that are incompletely understood. Glucose metabolism through the pentose phosphate pathway (PPP) produces NADPH that can protect cells from potentially lethal reactive oxygen species (ROS). We compared apoptosis and glucose metabolism in cancer cells with and without MDM2 gene amplification treated with Nutlin-3a. Apoptosis in MDM2-amplified cells was associated with a reduction in glycolysis and the PPP, reduced NADPH, increased ROS, and depletion of the transcription factor SP1, which normally promotes PPP gene expression. In contrast, glycolysis and the PPP were maintained or increased in MDM2 non-amplified cells treated with Nutlin-3a. This was dependent on p53 mediated AKT activation and was associated with maintenance of SP1 and continued expression of PPP genes. Knockdown or inhibition of AKT, SP1, or the PPP sensitized MDM2-non-amplified cells to apoptosis. The data indicate that p53 promotes AKT and SP1-dependent activation of the PPP that protects cells from Nutlin-3a-induced apoptosis. These findings provide insight into how glucose metabolism reduces Nutlin-3a-induced apoptosis, and also provide a mechanism for the heightened sensitivity of MDM2-amplified cells to apoptosis in response to Nutlin-3a. PMID- 29190378 TI - Bilingual Text With or Without Pictograms Improves Elderly Singaporeans' Understanding of Prescription Medication Labels. AB - Background and Objectives: In Singapore, primarily English-language prescription medication labels challenge elderly Singaporeans, many of whom are unable to read English. We investigated whether bilingual text and pictograms can help them understand prescription medication labels. Research Design and Methods: We randomized 1,414 elderly respondents of a national survey into four prescription medication labels: English-text; English-text-and-pictograms; Bilingual-text; and Bilingual-text-and-pictograms, which were similar except for the addition of another language and/or pictograms (International Pharmaceutical Federation, FIP). Respondents answered 16 label-related questions; an expert panel rated answers for correctness. Outcomes were (1) complete understanding (16 correct); (2) any understanding (>=1 correct); and (3) number of incorrect answers among those with any understanding. We evaluated associations of each prescription medication label (vs. English-text) with outcomes (1), (2), and (3) using logistic and negative binomial regression, respectively. Results: The elderly respondents were similar across the four prescription medication labels (English text, English-text-and-pictograms, Bilingual-text, Bilingual-text-and pictograms), for which the proportions with outcomes (1) and (2) were (17.9%, 25.6%, 36.9%, 40.1%) and (50.4%, 62.6%, 75.9%, 76.5%), respectively. We observed statistically significant higher odds of outcomes (1) and (2) among those assigned the three labels (vs. English-text): English-text-and-pictograms, 1.96 and 2.51; Bilingual-text, 3.54 and 6.73; and Bilingual-text-and-pictograms, 4.51 and 7.93. Those assigned the three labels also had 0.94, 1.98, and 2.12 fewer outcome (3) on average (vs. English-text). Discussion and Implications: Adding bilingual text with or without pictograms on prescription medication labels considerably improved elderly Singaporeans' understanding of the labels, strongly suggesting its application in practice. Other issues in prescription medication labels design and content, including adapting FIP pictograms for elderly Singaporeans, warrant further investigation. PMID- 29190379 TI - Fungal-specific Cyp51 inhibitor VT-1598 demonstrates in vitro activity against Candida and Cryptococcus species, endemic fungi, including Coccidioides species, Aspergillus species and Rhizopus arrhizus. AB - Background: Invasive fungal infections, including those caused by yeasts, moulds and endemic organisms, can be significant causes of morbidity and mortality in immunocompromised hosts, those with multiple comorbidities and occasionally immunocompetent hosts. Current antifungal agents are often limited by drug toxicities, drug interactions or the development of resistance. VT-1598 is a novel tetrazole that has greater specificity for fungal Cyp51 than currently available triazoles and thus the potential for clinically significant drug interactions is reduced. We measured the in vitro activity of VT-1598 against clinical isolates of Candida and Cryptococcus species, endemic fungi, including Coccidioides, Blastomyces and Histoplasma, Aspergillus species and Rhizopus arrhizus. Methods: Antifungal susceptibility testing was performed by broth microdilution or macrodilution methods per CLSI standards. Clinical isolates of each species were used and clinically available antifungal agents were tested against each isolate. Results: VT-1598 demonstrated in vitro activity against yeasts and moulds that was similar to or greater than that of clinically available antifungal agents, including amphotericin B, fluconazole, caspofungin, voriconazole and posaconazole. The in vitro activity of VT-1598 was also maintained against resistant isolates, including fluconazole-resistant Candida isolates. In vitro activity was also observed against endemic fungi, including Blastomyces, Histoplasma and both Coccidioides immitis and Coccidioides posadasii. Conclusions: VT-1598 demonstrated in vitro activity against yeasts, moulds and endemic fungi, which was maintained against isolates that had reduced susceptibility to other antifungals. Further studies are warranted to evaluate the in vivo efficacy of VT-1598 against various fungal pathogens. PMID- 29190377 TI - European Society of Cardiology: Cardiovascular Disease Statistics 2017. AB - Aims: The European Society of Cardiology (ESC) Atlas has been compiled by the European Heart Agency to document cardiovascular disease (CVD) statistics of the 56 ESC member countries. A major aim of this 2017 data presentation has been to compare high-income and middle-income ESC member countries to identify inequalities in disease burden, outcomes, and service provision. Methods and results: The Atlas utilizes a variety of data sources, including the World Health Organization, the Institute for Health Metrics and Evaluation, and the World Bank to document risk factors, prevalence, and mortality of cardiovascular disease and national economic indicators. It also includes novel ESC-sponsored survey data of health infrastructure and cardiovascular service provision provided by the national societies of the ESC member countries. Data presentation is descriptive with no attempt to attach statistical significance to differences observed in stratified analyses. Important differences were identified between the high income and middle-income member countries of the ESC with regard to CVD risk factors, disease incidence, and mortality. For both women and men, the age standardized prevalence of hypertension was lower in high-income countries (18% and 27%) compared with middle-income countries (24% and 30%). Smoking prevalence in men (not women) was also lower (26% vs. 41%) and together these inequalities are likely to have contributed to the higher CVD mortality in middle-income countries. Declines in CVD mortality have seen cancer becoming a more common cause of death in a number of high-income member countries, but in middle-income countries declines in CVD mortality have been less consistent where CVD remains the leading cause of death. Inequalities in CVD mortality are emphasized by the smaller contribution they make to potential years of life lost in high-income countries compared with middle-income countries both for women (13% vs. 23%) and men (20% vs. 27%). The downward mortality trends for CVD may, however, be threatened by the emerging obesity epidemic that is seeing rates of diabetes increasing across all the ESC member countries. Survey data from the National Cardiac Societies showed that rates of cardiac catheterization and coronary artery bypass surgery, as well as the number of specialist centres required to deliver them, were greatest in the high-income member countries of the ESC. The Atlas confirmed that these ESC member countries, where the facilities for the contemporary treatment of coronary disease were best developed, were often those in which declines in coronary mortality have been most pronounced. Economic resources were not the only driver for delivery of equitable cardiovascular health care, as some middle-income ESC member countries reported rates for interventional procedures and device implantations that matched or exceeded the rates in wealthier member countries. Conclusion: In documenting national CVD statistics, the Atlas provides valuable insights into the inequalities in risk factors, health care delivery, and outcomes of CVD across the ESC member countries. The availability of these data will underpin the ESC's ambitious mission 'to reduce the burden of cardiovascular disease' not only in its member countries but also in nation states around the world. PMID- 29190380 TI - Relationship-centered health care as a Lean intervention. AB - Continuous improvement efforts, recognized in much literature as Lean management techniques have been used in efforts to improve efficiency in democratic health care contexts for some time to varying degrees of success. The complexity of the health care system is magnified by the sheer number of processes and sub processes required to deliver value within a bureaucratic environment, while maintaining some level of compassionate and personalized care. There is inherent tension between what is required to be efficient and what is required to be caring and this conflict presses against Lean practice at the level of delivery.Administration and care intersect at the point of the patient's experience. In order to achieve the dual goals of improved value and lower costs, the application of Lean thinking for meaningful health care reform must acknowledge the fundamental dichotomy between the impersonal tasks required to provide health services, and human interactions. Meaningful health care reform requires an acknowledgement of this distinction, currently not recognized in literature. While administrative process improvements are necessary, they are insufficient to achieve a sustainable and caring health care system. Lean thinking must be applied differently for administrative processes and patient care encounters, because these are fundamentally different processes. In this way, Lean principles will effectively contribute to sustainable health system improvements.

PMID- 29190381 TI - Expression of MdCCD7 in the scion determines the extent of sylleptic branching and the primary shoot growth rate of apple trees. AB - Branching has a major influence on the overall shape and productivity of a plant. Strigolactones (SLs) have been identified as plant hormones that have a key role in suppressing the outgrowth of axillary meristems. CAROTENOID CLEAVAGE DIOXYGENASE (CCD) genes are integral to the biosynthesis of SLs and are well characterized in annual plants, but their role in woody perennials is relatively unknown. We identified CCD7 and CCD8 orthologues from apple and demonstrated that MdCCD7 and MdCCD8 are able to complement the Arabidopsis branching mutants max3 and max4 respectively, indicating conserved function. RNAi lines of MdCCD7 show reduced gene expression and increased branching in apple. We performed reciprocal grafting experiments with combinations of MdCCD7 RNAi and wild-type 'Royal Gala' as rootstocks and scion. Unexpectedly, wild-type roots were unable to suppress branching in MdCCD7 RNAi scions. Another key finding was that MdCCD7 RNAi scions initiated phytomers at an increased rate relative to the wild type, resulting in a greater node number and primary shoot length. We suggest that localized SL biosynthesis in the shoot, rather than roots, controls axillary bud outgrowth and shoot growth rate in apple.

During her two-year participation, she drew on various theoretical perspectives, including critical and community development approaches that not only influence her professional social work perspective, but extend to her personal worldview. In a rapidly emerging biotechnological age, this article contributes a holistic perspective, bringing into focus theory and practice; issues of human experience, human rights, and oppressive relationships; tensions between agency and structure (particularly relating to disability from a social model of disability and the medical model); and practical applications of artificial vision. Beyond its practical applications, illuminated is the relevance of community development values and principles such as a sense of connectedness, participation, and empowerment, which are understood in terms of an antioppressive perspective. The article concludes by recognizing the potential benefit of bionic vision for vision-impaired and blind people in their everyday lives. PMID- 29190384 TI - General practitioner and nurse prescriber experiences of prescribing antibiotics for respiratory tract infections in UK primary care out-of-hours services (the UNITE study). AB - Background: Interventions are needed to reduce unnecessary antibiotic prescribing for respiratory tract infections (RTIs). Although community antibiotic prescribing appears to be decreasing in the UK, figures for out-of-hours (OOH) prescribing have substantially increased. Understanding the factors influencing prescribing in OOH and any perceived differences between general practitioner (GP) and nurse prescriber (NP) prescribing habits may enable the development of tailored interventions promoting optimal prescribing in this setting. Objectives: To explore UK GP and NP views on and experiences of prescribing antibiotics for RTIs in primary care OOH services. Methods: Thirty semi-structured interviews were conducted with GPs and NPs working in primary care OOH services. Inductive thematic analysis was used to analyse data. Results: The research shows that factors particular to OOH influence antibiotic prescribing, including a lack of patient follow-up, access to patient GP records, consultation time, working contracts and implementation of feedback, audit and supervision. NPs reported perceptions of greater accountability for their prescribing compared with GPs and reported they had longer consultations during which they were able to discuss decisions with patients. Participants agreed that more complex cases should be seen by GPs and highlighted the importance of consistency of decision making, illness explanations to patients as well as a perception that differences in clinical training influence communication with patients and antibiotic prescribing decisions. Conclusions: Environmental and social factors in OOH services and a mixed healthcare workforce provide unique influences on antibiotic prescribing for RTIs, which would need to be considered in tailoring interventions that promote prudent antibiotic prescribing in OOH services.

AB - Atypical DNA secondary structures play an important role in expandable trinucleotide repeat (TR) and hexanucleotide repeat (HR) diseases. The cytosine mismatches in C-rich homoduplexes and hairpin stems are weakly bonded; experiments show that for certain sequences these may flip out of the helix core, forming an unusual structure termed an 'e-motif'. We have performed molecular dynamics simulations of C-rich TR and HR DNA homoduplexes in order to characterize the conformations, stability and dynamics of formation of the e motif, where the mismatched cytosines symmetrically flip out in the minor groove, pointing their base moieties towards the 5'-direction in each strand. TRs have two non-equivalent reading frames, (GCC)n and (CCG)n; while HRs have three: (CCCGGC)n, (CGGCCC)n, (CCCCGG)n. We define three types of pseudo basepair steps related to the mismatches and show that the e-motif is only stable in (GCC)n and (CCCGGC)n homoduplexes due to the favorable stacking of pseudo GpC steps (whose nature depends on whether TRs or HRs are involved) and the formation of hydrogen bonds between the mismatched cytosine at position i and the cytosine (TRs) or guanine (HRs) at position i - 2 along the same strand. We also characterize the extended e-motif, where all mismatched cytosines are extruded, their extra helical stacking additionally stabilizing the homoduplexes.

AB - Ration of food per capita of larval population is widely thought to limit mosquito production from container habitats, directly reflecting resource limitation. In this study, the importance of density-dependent resource limitation on larval Aedes triseriatus (Say) (Diptera: Culicidae) depended on the degree of microbial conditioning of senescent leaf detritus in surrogate tree holes. Density and ration strongly affected emergence, total female mass, and mean female mass of populations grown on leaves that had conditioned for 3 d, but had less impact when larval populations were grown on leaves that had conditioned for 1 mo. Ration per capita was a stronger predictor (50-94% of the variance) of all growth parameters measured for populations grown on leaves conditioned for 3 d compared with 1 mo (2-66% of variance), with the exception of development time. Larvae grew faster and to a larger body size on leaves conditioned for 3 d at low densities of larvae and a higher ration per capita. However, populations grown on leaves conditioned for 1 mo produced equal or more total mass and individuals of higher average mass than when grown on leaves conditioned for 3 d in treatments with low ration per capita. Well-conditioned detritus, representing the degree of microbial colonization of the organic material, must reflect the typical condition in tree holes with unconditioned leaves atypical. Therefore, results of this study suggest that experiments using well-conditioned leaves better estimate growth responses, including moderated density dependence and less importance of ration per capita, than experiments using unconditioned detritus. PMID- 29190387 TI - Chronic hyperandrogenemia in the presence and absence of a western-style diet impairs ovarian and uterine structure/function in young adult rhesus monkeys. AB - STUDY QUESTION: Does chronic hyperandrogenemia beginning at menarche, in the absence and presence of a western-style diet (WSD), alter ovarian and uterine structure-function in young adult rhesus monkeys? SUMMARY ANSWER: Phenotypic alterations in ovarian and uterine structure/function were induced by exogenous testosterone (T), and compounded in the presence of a WSD (T+WSD). WHAT IS KNOWN ALREADY: Hyperandrogenemia is a well-established component of PCOS and is observed in adolescent girls, indicating a potential pubertal onset of disease symptoms. Obesity is often associated with hyperandrogenemia and it is hypothesized that metabolic dysfunction exacerbates PCOS symptoms. STUDY DESIGN, SIZE, DURATION: Macaque females (n = 40) near the onset of menarche (~2.5 years of age) were assigned to a 2 by 2 factorial cohort design. Effects on reproductive characteristics were evaluated after 3 years of treatment. PARTICIPANTS/MATERIALS, SETTING, METHODS: Rhesus macaques (Macaca mulatta) were fed either a normal balanced diet (n = 20) or a WSD (n = 20). Additionally, implants containing cholesterol (n = 20) or T (n = 20) were implanted subcutaneously to elevate serum T approximately 5-fold. This resulted in treatment groups of controls (C), T, WSD and T+WSD (n = 10/group). Vaginal swabbing was performed daily to detect menses. After 3 years of treatment, daily serum samples from one menstrual cycle were assayed for hormone levels. Ovarian structure was evaluated in the early follicular phase by 3D/4D ultrasound. Uterine endometrial size and ovarian/luteal vascular function was also evaluated in subgroups (n = 6/group) in the late follicular and mid-luteal phases by 3D/4D ultrasound and contrast-enhanced ultrasound, respectively. Expression of steroid hormone receptors and markers of decidualization and endometrial receptivity were assessed in endometrial biopsies at mid-luteal phase. MAIN RESULTS AND THE ROLE OF CHANCE: Approximately 90% of menstrual cycles appeared ovulatory with no differences in frequency or duration between groups. Serum estradiol (E2) levels during the early follicular phase were greatest in the T alone group, but reduced in T+WSD (P < 0.02). Serum LH was elevated in the T group (P < 0.04); however, there were no differences among groups in FSH levels (P > 0.13). Ovarian size at menses tended to be greater in the WSD groups (P < 0.07) and antral follicles >=1 mm were more numerous in the T+WSD group (P < 0.05). Also, females in T and T+WSD groups displayed polycystic ovarian morphology (PCOM) at greater frequency than C or WSD groups (P < 0.01). Progesterone (P4) levels during the luteal phase were reduced in the T+WSD group compared to C and T groups (P < 0.05). Blood volume (BV) and vascular flow (VF) within the corpus luteum was reduced in all treatment groups compared to C (P < 0.01, P = 0.03), with the WSD alone group displaying the slowest BV and VF (P < 0.05). C and WSD groups displayed endometrial glands at mid-luteal phase with low estrogen receptor 1 (ESR1) and progesterone receptor (PGR) mRNA and immunohistochemical staining in the functionalis zone, but appreciable PGR in the stroma. In contrast, T and T+WSD treatment resulted in glands with less secretory morphology, high ESR1 expression in the glandular epithelium and low PGR in the stroma. Endometrial levels of TIMP3 and MMP26 mRNA and immunostaining were also decreased in the T and T+WSD groups, whereas AR expression was unchanged. LARGE SCALE DATA: None. LIMITATIONS, REASONS FOR CAUTION: Females are young adults, so effects could change as they reach prime reproductive age. The T level generated for hyperandrogenemia may be somewhat greater than the 3-4-fold increase observed in adolescent girls, but markedly less than those observed in male monkeys or adolescent boys. WIDER IMPLICATIONS OF THE FINDINGS: Alterations to ovarian and uterine structure-function observed in T and, in particular, T+WSD-treated female macaques are consistent with some of the features observed in women diagnosed with polycystic ovary syndrome (PCOS), and suggest impaired fertility.

PMID- 29190388 TI - INP1 involvement in pollen aperture formation is evolutionarily conserved and may require species-specific partners. AB - Pollen wall exine is usually deposited non-uniformly on the pollen surface, with areas of low exine deposition corresponding to pollen apertures. Little is known about how apertures form, with the novel Arabidopsis INP1 (INAPERTURATE POLLEN1) protein currently being the only identified aperture factor. In developing pollen, INP1 localizes to three plasma membrane domains and underlies formation of three apertures. Although INP1 homologs are found across angiosperms, they lack strong sequence conservation. Thus, it has been unclear whether they also act as aperture factors and whether their sequence divergence contributes to interspecies differences in aperture patterns. To explore the functional conservation of INP1 homologs, we used mutant analysis in maize and tested whether homologs from several other species could function in Arabidopsis. Our data suggest that the INP1 involvement in aperture formation is evolutionarily conserved, despite the significant divergence of INP1 sequences and aperture patterns, but that additional species-specific factors are likely to be required to guide INP1 and to provide information for aperture patterning. To determine the regions in INP1 necessary for its localization and function, we used fragment fusions, domain swaps, and interspecific protein chimeras. We demonstrate that the central portion of the protein is particularly important for mediating the species-specific functionality. PMID- 29190389 TI - A Bayesian Approach for Measurements of Stray Neutrons at Proton Therapy Facilities: Quantifying Neutron Dose Uncertainty. AB - Bonner sphere measurements are typically analyzed using unfolding codes. It is well known that it is difficult to get reliable estimates of uncertainties for standard unfolding procedures. An alternative approach is to analyze the data using Bayesian parameter estimation. This method provides reliable estimates of the uncertainties of neutron spectra leading to rigorous estimates of uncertainties of the dose. We extend previous Bayesian approaches and apply the method to stray neutrons in proton therapy environments by introducing a new parameterized model which describes the main features of the expected neutron spectra. The parameterization is based on information that is available from measurements and detailed Monte Carlo simulations. The validity of this approach has been validated with results of an experiment using Bonner spheres carried out at the experimental hall of the OncoRay proton therapy facility in Dresden. PMID- 29190390 TI - Mistletoe-induced growth reductions at the forest stand scale. AB - The hemiparasite European mistletoe (Viscum album L.) adversely affects growth and reproduction of the host Scots pine (Pinus sylvestris L.) and in consequence may lead to tree death. Here, we aimed to estimate mistletoe-induced losses in timber yield applying the process-based forest growth model 4C. The parasite was implemented into the eco-physiological forest growth model 4C using (literature derived) established impacts of the parasite on the tree's water and carbon cycle. The amended model was validated simulating a sample forest stand in the Berlin area (Germany) comprising trees with and without mistletoe infection. At the same forest stand, tree core measurements were taken to evaluate simulated and observed growth. A subsample of trees were harvested to quantify biomass compartments of the tree canopy and to derive a growth function of the mistletoe population. The process-based simulations of the forest stand revealed 27% reduction in basal area increment (BAI) during the last 9 years of heavy infection, which was confirmed by the measurements (29% mean growth reduction). The long-term simulations of the forest stand before and during the parasite infection showed that the amended forest growth model 4C depicts well the BAI growth pattern during >100 years and also quantifies well the mistletoe-induced growth reductions in Scots pine stands.

AB - Objectives: We examined older adults' social reminiscence behavior in everyday life, and the relation between reminiscence functions and well-being. Method: The sample included 2,164 sound snippets that included speech from 45 healthy older adults. We examined reminiscence in daily conversations using the Electronically Activated Recorder. Across four days, we collected a random sample of about 280 sound files (30 seconds long) per participant. Participants' utterances were coded for whether they included reminiscence, for their functions and conversation partners. Participants completed mood and life satisfaction measures. Results: Participants reminisced in 5% of their utterances (range: 0% 29%). They reminisced in 40% of cases with friends, 32.8% with their partner and 8% with their children/relatives. Three reminiscence functions were observed: identity, teaching/informing, and conversation. Participants' reminiscence served the identity function while they were reminiscing with their partner and children. Participants reminisced to teach/inform while reminiscing with their children and strangers. Reminiscing for conversation occurred mainly with partner and friends. We found positive relations between life satisfaction and identity, teach/inform, and conversation functions. Mood had a negative relation with identity and teach/inform functions. Discussion: This is the first study to take a naturalistic observation approach to reminiscence and to build on self-report data. PMID- 29190391 TI - Radiotherapy for locally advanced resectable T3-T4 laryngeal cancer-does laryngeal preservation strategy compromise survival? AB - With the advancement of chemotherapy, a laryngeal preservation (LP) strategy was explored with the aim of improving maintenance of quality of life. Induction chemotherapy (ICT) following radiotherapy (RT) was considered a viable option because of its high initial response rate without hampering of overall survival (OS). Subsequently, concurrent chemoradiotherapy (CCRT) using CDDP became the standard of care for LP, showing the best LP ratio. For enhancing treatment intensity, ICT with taxan + CDDP + 5-FU (TPF-ICT) followed by RT showed superiority over ICT with CDDP + 5-FU (PF-ICT) followed by RT. Given that almost all randomized controlled trials investigating ICT include not only operable (endpoint, LP) but also inoperable (endpoint, OS) cases, physicians are faced with a dilemma regarding application in daily practice. In addition, increased treatment intensity causes augmentation of adverse events, which might reduce compliance. Thereafter, cetuximab, an effective drug with fewer adverse effects [bioradiotherapy (BRT)], emerged as another option. However, little evidence has confirmed its superiority over RT (or CCRT) in laryngeal cancer subpopulations. In spite of these developments, the OS of patients with laryngeal cancer has not improved for several decades. In fact, several studies indicated a decrease in OS during the 1990s, probably due to overuse of CCRT. Fortunately, the latter was not the case in most institutions. Currently, no other treatment has better OS than surgery. The eligibility criteria for LP and/or surgery largely depend upon the available expertise and experience, which differ from one institution to another. Therefore, a multidisciplinary team is required for the treatment of LP. PMID- 29190393 TI - Exchanging missives and missiles: the roles of extracellular vesicles in plant pathogen interactions. PMID- 29190394 TI - Acetylation of 53BP1 dictates the DNA double strand break repair pathway. AB - P53-binding protein 1 (53BP1) plays critical roles in DNA double strand break (DSB) repair by promoting non-homologous end joining (NHEJ), and loss of 53BP1 abolishes PARPi sensitivity in BRCA1-deficient cells by restoring homologous recombination (HR). 53BP1 is one of the proteins initially recruited to sites of DSBs via recognition of H4K20me2 through the Tudor-UDR domain and H2AK15ub through the UDR motif. Although extensive studies have been conducted, it remains unclear how the post-translational modification of 53BP1 affects DSB repair pathway choice. Here, we identified 53BP1 as an acetylated protein and determined that acetylation of 53BP1 inhibit NHEJ and promote HR by negatively regulating 53BP1 recruitment to DSBs. Mechanistically, CBP-mediated acetylation of K1626/1628 in the UDR motif disrupted the interaction between 53BP1 and nucleosomes, subsequently blocking the recruitment of 53BP1 and its downstream factors PTIP and RIF1 to DSBs. Hyperacetylation of 53BP1, similar to depletion of 53BP1, restored PARPi resistance in BRCA1-deficient cells. Interestingly, 53BP1 acetylation was tightly regulated by HDAC2 to maintain balance between the HR and NHEJ pathways. Together, our results demonstrate that the acetylation status of 53BP1 plays a key role in its recruitment to DSBs and reveal how specific 53BP1 modification modulates the choice of DNA repair pathway. PMID- 29190395 TI - Subjective social status and trajectories of self-rated health status: a comparative analysis of Japan and the United States. AB - Background: Japanese society is more egalitarian than the United States as is reflected by the lower degree of prevalence of social inequalities in health. We examined whether subjective socioeconomic status is associated with different trajectories of self-rated health (SRH), and whether this relationship differs between the United States and Japan. Methods: We analyzed the responses of 3968 Americans from the survey Midlife in the United States, 2004-06, and the responses of 989 Japanese from the survey Midlife in Japan, 2008. We conducted a multilevel analysis with three self-ratings of health (10 years ago, current and 10 years in the future) nested within individuals and nested within 10 levels of subjective social status. Age, sex, educational level and subjective financial situation were adjusted. Results: After making statistical adjustments for confounding variables, respondents in Japan continued to report lower average levels of health. However, the rate of expected decline in SRH over the next decade was strongly socially patterned in the United States, whereas it was not in Japan. Conclusion: The Japanese showed no disparity in the anticipated trajectory of SRH over time, whereas the Americans showed a strong social class gradient in future trajectories of SRH. PMID- 29190397 TI - The international nucleotide sequence database collaboration. AB - For more than 30 years, the International Nucleotide Sequence Database Collaboration (INSDC; http://www.insdc.org/) has been committed to capturing, preserving and providing access to comprehensive public domain nucleotide sequence and associated metadata which enables discovery in biomedicine, biodiversity and biological sciences. Since 1987, the DNA Data Bank of Japan (DDBJ) at the National Institute for Genetics in Mishima, Japan; the European Nucleotide Archive (ENA) at the European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI) in Hinxton, UK; and GenBank at National Center for Biotechnology Information (NCBI), National Library of Medicine, National Institutes of Health in Bethesda, Maryland, USA have worked collaboratively to enable access to nucleotide sequence data in standardized formats for the worldwide scientific community. In this article, we reiterate the principles of the INSDC collaboration and briefly summarize the trends of the archival content. PMID- 29190396 TI - Distinct reaction mechanisms for hyaluronan biosynthesis in different kingdoms of life. AB - Hyaluronan (HA) is an acidic high molecular weight cell surface polysaccharide ubiquitously expressed by vertebrates, some pathogenic bacteria and even viruses. HA modulates many essential physiological processes and is implicated in numerous pathological conditions ranging from autoimmune diseases to cancer. In various pathogens, HA functions as a non-immunogenic surface polymer that reduces host immune responses. It is a linear polymer of strictly alternating glucuronic acid and N-acetylglucosamine units synthesized by HA synthase (HAS), a membrane embedded family-2 glycosyltransferase. The enzyme synthesizes HA and secretes the polymer through a channel formed by its own membrane-integrated domain. To reveal how HAS achieves these tasks, we determined the biologically functional units of bacterial and viral HAS in a lipid bilayer environment by co-immunoprecipitation, single molecule fluorescence photobleaching, and site-specific cross-linking analyses. Our results demonstrate that bacterial HAS functions as an obligate homo-dimer with two functional HAS copies required for catalytic activity. In contrast, the viral enzyme, closely related to vertebrate HAS, functions as a monomer. Using site-specific cross-linking, we identify the dimer interface of bacterial HAS and show that the enzyme uses a reaction mechanism distinct from viral HAS that necessitates a dimeric assembly. PMID- 29190398 TI - The response of young adult smokers and non-smokers in the United Kingdom to dissuasive cigarettes: An online survey. AB - Introduction: The cigarette stick is an important communications tool as well as the object of consumption. We explored young adults' responses to cigarettes designed to be dissuasive. Methods: Data come from a cross-sectional online survey, conducted in September 2015, with 16-24 year old smokers and non-smokers (N=997) in the United Kingdom. Participants were shown images of a standard cigarette (white cigarette paper with imitation cork filter), a standard cigarette displaying the warning 'Smoking kills' on the cigarette paper, and an unattractively coloured cigarette (green cigarette paper and filter). They were asked to rate each of the three cigarettes, shown individually, on eight perception items, and to rate the three cigarettes, shown together, on how likely they would be to try them. Ordering of the cigarettes and questions, with the exception of the question on trial, was randomised. Results: The eight perceptions items were combined to form a composite measure of cigarette perceptions. For smokers and non-smokers, the two dissuasive cigarettes (cigarette with warning, green cigarette) were rated significantly less favourably than the standard cigarette, and less likely to encourage trial. For cigarette perceptions no significant interaction was detected between cigarette style and smoking status or susceptibility to smoke among never smokers. A significant interaction was found for likelihood of trying the cigarettes, with dissuasive cigarettes having a greater impact with smokers than non-smokers. Conclusions: This study suggests that dissuasive cigarettes may help to reduce the desirability of cigarettes. Implications: The cigarette stick is the object of tobacco consumption, which is seen every time a cigarette is smoked. It is also an increasingly important promotional tool for tobacco companies. In this study, young adults rated two dissuasive cigarettes (a green coloured cigarette and a cigarette displaying a health warning) more negatively than a standard cigarette, and considered them less likely to encourage product trial. Our findings suggest that it may be possible to reduce the desirability of cigarette sticks by altering their design, e.g., with the addition of a warning or use of an unattractive colour. PMID- 29190399 TI - Creating a Medical Workforce That Looks Like America: Community Colleges Have a Major Role. PMID- 29190400 TI - Interest in Family Medicine Among US Medical Students and Its Association With a Community College Academic Pathway. AB - BACKGROUND AND OBJECTIVES: One-third of all medical students attend a community college (CC) on their path to medical school. The objective of this study was to examine the association between CC participation and initial specialty of interest among US allopathic medical students. METHODS: We performed a national cross-sectional study of allopathic medical students who completed the 2012 Association of American Medical Colleges' Matriculating Student Questionnaire. Bivariate and logistic regression analyses were conducted. RESULTS: A total of 9,885 medical student respondents were included in the study sample, consisting of 7,035 (71%) non-CC pathway, and 2,850 (29%) CC pathway participants. CC pathway participants were more likely to express intent to specialize in family medicine (272/2,850 [10%] vs 463/7,035 [7%], P<.001), compared to those on the non-CC path. CC pathway participants had higher odds of intent to specialize in family medicine (adjusted odds ratio [AOR]=1.32; 95% CI 1.13-1.56, P<0.001), compared to those on the non-CC path. Women, independent of college pathway, were nearly two times more likely to express an intention to specialize in family medicine, and three times more likely to express an intention to specialize in pediatrics than men. CONCLUSIONS: Medical students who used a CC pathway are more likely to have intentions to specialize in family medicine, compared to those on the non-CC path. PMID- 29190401 TI - Addressing Food Insecurity in Family Medicine and Medical Education. AB - BACKGROUND AND OBJECTIVES: Food insecurity is associated with poor health outcomes, yet is not routinely addressed in health care. This study was conducted to determine if education regarding food insecurity as a health issue could modify knowledge, attitudes, and clinical behavior. METHODS: Educational sessions on food insecurity and its impact on health were conducted in 2015 at three different family medicine residency programs and one medical school. A pre/post survey was given immediately before and after this session. Attendees were encouraged to identify and implement individual and system-based changes to integrate food insecurity screening and referrals into their clinical practices. Participants completed follow-up surveys approximately 1 year later, and the authors obtained systems-level data from electronic health records and databases. Pre/post means (SD) were compared using t-tests. The numbers of patients screened and referred were calculated. RESULTS: Eighty-five participants completed the pre/post survey during the educational sessions (51 medical students, 29 residents, 5 faculty). Self-reported knowledge of food insecurity, resources, and willingness to discuss with patients increased (P<0.0001 for all). Each program identified a feasible systems-based change. Follow-up surveys demonstrated increased discussion of food insecurity during clinical visits and referrals to food resources. Over 1,600 patients were screened for food insecurity as a result of systems-based changes. CONCLUSIONS: Educational interventions focused on the role of food insecurity in health can produce improvements in knowledge and attitudes toward addressing food insecurity, increase discussions with patients about food insecurity, and result in measurable patient and systems-level changes. PMID- 29190402 TI - Resident and Residency Characteristics Associated With Self-reported Preparedness for Population Health Management. AB - BACKGROUND AND OBJECTIVES: Population health management (PHM) is an important function of primary care with potential to improve outcomes and decrease costs, but is also among the most difficult strategies to implement in both practices and residency training. Our objective was to determine resident and residency program characteristics associated with graduates' reported preparation to perform PHM. METHODS: We used data from the American Board of Family Medicine (ABFM) Certification Examination registration questionnaire in 2014 and 2015 and ABFM administrative data. Resident PHM preparedness was assessed via a single, self-reported question. Bivariate analysis and logistic multilevel regression were performed to determine independent associations between characteristics and reported PHM preparedness. Odds ratios were converted to risk ratios given the high prevalence of the outcome. RESULTS: Our sample included 6,135 residents from 442 family medicine residencies. Sixty-nine percent (n=4,240) reported being extremely or moderately prepared to perform PHM. No residency program characteristics showed an association with reported PHM preparedness. Resident characteristics independently associated with reported preparedness included being an international medical graduate (IMG) (RR=1.21 [1.07-1.35]) and of Hispanic ethnicity. Reporting greater preparedness to use health information tools, to lead quality improvement projects, and to provide care in different settings were also associated with reported PHM preparedness. CONCLUSIONS: Similar to a study of practicing physicians, we found that IMGs are more likely to report preparedness to perform PHM. This suggests that elements of international medical education may better inculcate PHM principles, and that these elements could be used to produce physicians better prepared to manage population health. PMID- 29190403 TI - Family Medicine Didactics Revisited. AB - BACKGROUND AND OBJECTIVES: All family medicine programs are required to provide specialty-specific didactic conferences for residents. Since a baseline study of family medicine didactic formats was published in 2000, training requirements have changed, core content has evolved, and new teaching strategies have been recommended. The present study examines the characteristics of current family medicine didactics, compares current and past conference format data, and identifies factors affecting content selection. METHODS: The survey used in the prior conference formats study was distributed to all US family medicine programs. All questions from the original survey were repeated, and items regarding factors affecting conference content and threats to conferences were added. RESULTS: The survey response rate was 66%. The majority of family medicine programs endorse block formats for structuring conferences. Compared to the original study, programs are devoting significantly more hours to didactics on fewer days. Family medicine faculty and residents are responsible for 70% of didactic offerings (also a significant shift), and 87% of programs use a core curriculum. In over 70% of programs, some residents are unavailable for conferences due to work restrictions or service demands. The Accreditation Council for Graduate Medical Education subcompetencies and Milestones have only a moderate impact on topic selection. CONCLUSIONS: Family medicine didactics have evolved in the past 15 years with a notable increase in reliance upon core faculty and residents to lead conferences. Reduced availability of residents prevents all residents from having full exposure to the didactic curriculum. Family medicine faculty who are taking greater responsibility for didactics are also faced with increased clinical and administrative duties. PMID- 29190404 TI - Sex Ed by Brown Med: A Student-Run Curriculum and Its Impact on Sexual Health Knowledge. AB - BACKGROUND AND OBJECTIVES: Risky sexual behavior among adolescents is a public health crisis. We describe a novel approach to sexual health education where medical students manage a curriculum for an entire seventh grade in one Rhode Island city to better equip students with comprehensive knowledge about sexual health. METHODS: Medical students were trained to teach 12 sessions to seventh grade students under the supervision of the classroom teacher using a curriculum designed by medical students and faculty (modeled on the Family Life and Sexual Health [FLASH] curriculum but tailored to meet the community's needs). Pre- and postassessment surveys were conducted during the 2015-2016 academic year. We analyzed survey data collected pre- and postprogram using IBM SPSS Statistics. RESULTS: Pre and postassessments were completed by 62% of students (74/120). Students completing the curriculum scored 8% higher on the postassessment vs the preassessment, (70.4% vs 62.32%, absolute difference=8.11%, P<0.001). Student knowledge improved in domains of pregnancy prevention, reproductive system/anatomy, general knowledge and prevention of sexually transmitted infections (STIs), safe sex practices, sexual assault, and sexual decision making. Respondents' perception of the importance of school-based sexual health lessons as well as their willingness to discuss sexual issues with an adult increased after completing the program. CONCLUSIONS: A year-long, middle school based sexual health program taught by medical students showed significant improvements in sexual health knowledge and increased willingness to engage in dialogue about sex with trusted adults. Adolescents may benefit from long-term interaction and instruction about sexual education from medical students. PMID- 29190405 TI - Are Self-study Procedural Teaching Methods Effective? A Pilot Study of a Family Medicine Residency Program. AB - BACKGROUND AND OBJECTIVES: A family medicine residency is a unique training environment where residents are exposed to care in multiple settings, across all ages. Procedures are an integral part of family medicine practice. Family medicine residency (FMR) programs are tasked with the job of teaching these skills at a level of intensity and frequency that allows a resident to achieve competency of such skills. In an environment that is limited by work hour restrictions, self-study teaching methods are one way to ensure all residents receive the fundamental knowledge of how to perform procedures. We developed and evaluated the efficacy of a self-study procedure teaching method and procedure evaluation checklist. METHODS: A self-study procedure teaching intervention was created, consisting of instructional articles and videos on three procedures. To assess the efficacy of the intervention, and the competency of the residents, pre and postintervention procedure performance sessions were completed. These sessions were reviewed and scored using a standardized procedure performance checklist. RESULTS: All 24 residents participated in the study. Overall, the resident procedure knowledge increased on two of the three procedures studied, and ability to perform procedure according to expert-validated checklist improved significantly on all procedures. CONCLUSIONS: A self-study intervention is a simple but effective way to increase and improve procedure training in a way that fits the complex scheduling needs of a residency training program. In addition, this study demonstrates that the procedure performance checklists are a simple and reliable way to increase assessment of resident procedure performance skills in a residency setting. PMID- 29190406 TI - Development of a Multifaceted Health Disparities Curriculum for Medical Residents. AB - BACKGROUND AND OBJECTIVES: Health disparities education is required during residency training. However, residency program directors cite numerous barriers to implementing disparities curricula, and few publications describing successful disparities curricula exist in the literature. In this report, we describe the development, implementation, and early evaluation of a longitudinal health disparities curriculum for resident physicians. We provide resource references, process, and didactic toolkits to facilitate use by other residency programs. METHODS: We used a standard, six-step model for curricular design, implementation, and evaluation. We assessed feasibility of curricular development including practicality (program cost and time requirements) and demand (resident engagement). We also assessed program and learner outcomes, including number of didactic and clinic sessions delivered and resident preparedness, attitudes, and skill in caring for vulnerable patients. RESULTS: We designed, implemented, and evaluated our curriculum in less than 1 year, with no external funding. Time costs included 100 chief resident and 20 faculty hours for curricular development, followed by 20 chief resident and 16 faculty hours for implementation. In the first year of our curriculum, 21% of residents (16 of 75) participated. We created eight didactic sessions and delivered four as intended. Residents provided 84 free clinic sessions for uninsured patients and reported increased preparedness and skill caring for vulnerable patients in 15 of 20 measured domains. Residents also reported 20 commitments to change on themes that comprehensively reflected the content of our first curricular year. CONCLUSIONS: It is possible to design a disparities curriculum, overcome cited barriers, and improve educational outcomes related to the care of vulnerable patients. PMID- 29190407 TI - Perceptions of Nutrition Education in the Current Medical School Curriculum. AB - BACKGROUND AND OBJECTIVES: Although the National Academy of Sciences has recommended a minimum of 25 hours of nutrition education, the majority of medical schools offer very little to no training or education in nutrition to medical students during their tenure in medical school. In order to assess the relevance and efficacy of current levels of nutrition training as viewed by students, residents, and physicians, as well as possible areas for further improvement, the authors conducted a qualitative study exploring students' experiences. METHODS: Medical students, residents, and physicians at a Midwestern medical school were interviewed during a series of eight focus groups and one-on-one interviews. Results were coded and analyzed using NVivo qualitative software for emerging themes. RESULTS: Medical students felt nutrition was poorly integrated into the curriculum. They witnessed little nutrition counseling during shadowing experiences, and the nutrition information that was imparted was often outdated or incorrect. Residents stated they felt ill-prepared to offer nutrition counseling and desired further education in this area. CONCLUSIONS: Overall, medical students and physicians agreed that the nutrition education currently provided in medical school is inadequate. Residents stated they would benefit from further training in behavioral counseling in order to increase their confidence in educating patients about nutrition. Increasing training in these areas could translate into improved health outcomes. PMID- 29190408 TI - Transformations. PMID- 29190409 TI - Bambi Keith.

AB - BACKGROUND: The prevalence of overweight and obesity is increasing globally, an increase which has major implications for both population health and costs to health services. This is an update of a Cochrane Review. OBJECTIVES: To assess the effects of strategies to change the behaviour of health professionals or the organisation of care compared to standard care, to promote weight reduction in children and adults with overweight or obesity. SEARCH METHODS: We searched the following databases for primary studies up to September 2016: CENTRAL, MEDLINE, Embase, CINAHL, DARE and PsycINFO. We searched the reference lists of included studies and two trial registries. SELECTION CRITERIA: We considered randomised trials that compared routine provision of care with interventions aimed either at changing the behaviour of healthcare professionals or the organisation of care to promote weight reduction in children and adults with overweight or obesity. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane when conducting this review. We report the results for the professional interventions and the organisational interventions in seven 'Summary of findings' tables. MAIN RESULTS: We identified 12 studies for inclusion in this review, seven of which evaluated interventions targeting healthcare professional and five targeting the organisation of care. Eight studies recruited adults with overweight or obesity and four recruited children with obesity. Eight studies had an overall high risk of bias, and four had a low risk of bias. In total, 139 practices provided care to 89,754 people, with a median follow-up of 12 months. Professional interventions Educational interventions aimed at general practitioners (GPs), may slightly reduce the weight of participants (mean difference (MD) -1.24 kg, 95% confidence interval (CI) -2.84 to 0.37; 3 studies, N = 1017 adults; low-certainty evidence).Tailoring interventions to improve GPs' compliance with obesity guidelines probably leads to little or no difference in weight loss (MD 0.05 (kg), 95% CI -0.32 to 0.41; 1 study, N = 49,807 adults; moderate-certainty evidence).It is uncertain if providing doctors with reminders results in a greater weight reduction than standard care (men: MD -11.20 kg, 95% CI -20.66 kg to -1.74 kg, and women: MD -1.30 kg, 95% CI [-7.34, 4.74] kg; 1 study, N = 90 adults; very low-certainty evidence).Providing clinicians with a clinical decision support (CDS) tool to assist with obesity management at the point of care leads to little or no difference in the body mass index (BMI) z score of children (MD -0.08, 95% CI -0.15 to -0.01 in 378 children; moderate certainty evidence), CDS tools may lead to little or no difference in weight loss in adults: MD -0.095 kg (-0.21 lbs), P = 0.47; 1 study, N = 35,665; low-certainty evidence. Organisational interventions Adults with overweight or obesity may lose more weight if the care was provided by a dietitian (by -5.60 kg, 95% CI -4.83 kg to -6.37 kg) or by a doctor-dietitian team (by -6.70 kg, 95% CI -7.52 kg to -5.88 kg; 1 study, N = 270 adults; low-certainty evidence). Shared care leads to little or no difference in the BMI z-score of children with obesity (adjusted MD -0.05, 95% CI -0.14 to 0.03; 1 study, N = 105 children; low-certainty evidence).Organisational restructuring of the delivery of primary care (i.e. introducing the chronic care model) may result in a slightly lower increase in the BMI of children who received care at intervention clinics (BMI change: adjusted MD -0.21, 95% CI -0.50 to 0.07; 1 study, unadjusted MD -0.18, 95% CI 0.20 to -0.16; N=473 participants; moderate-certainty evidence).Mail and phone interventions probably lead to little or no difference in weight loss in adults (mean weight change (kg) using mail: -0.36, 95% CI -1.18 to 0.46; phone: -0.44, 95% CI -1.26 to 0.38; 1 study, N = 1801 adults; moderate-certainty evidence). Care delivered by a nurse at a primary care clinic may lead to little or no difference in the BMI z-score in children (MD -0.02, 95% CI -0.16 to 0.12; 1 study, N = 52 children; very low-certainty evidence).Two studies reported data on cost effectiveness: one study favoured mail and standard care over telephone consultations, and the other study achieved weight loss at a modest cost in both intervention groups (doctor and doctor-dietitian). One study of shared care reported similar adverse effects in both groups. AUTHORS' CONCLUSIONS: We found little convincing evidence for a clinically-important effect on participants' weight or BMI of any of the evaluated interventions. While pooled results from three studies indicate that educational interventions targeting healthcare professionals may lead to a slight weight reduction in adults, the certainty of these results is low. Two trials evaluating CDS tools (unpooled results) for improved weight management suggest little or no effect on weight or BMI change in adults or children with overweight or obesity. Evidence for all the other interventions evaluated came mostly from single studies. The certainty of the included evidence varied from moderate to very low for the main outcomes (weight and BMI). All of the evaluated interventions would need further investigation to ascertain their strengths and limitations as effective strategies to change the behaviour of healthcare professionals or the organisation of care. As only two studies reported on cost, we know little about cost effectiveness across the evaluated interventions.

PMID- 29190421 TI - Exciton-Exciton Annihilation Is Coherently Suppressed in H-Aggregates, but Not in J-Aggregates. AB - We theoretically demonstrate a strong dependence of the annihilation rate between (singlet) excitons on the sign of dipole-dipole couplings between molecules. For molecular H-aggregates, where this sign is positive, the phase relation of the delocalized two-exciton wave functions causes a destructive interference in the annihilation probability. For J-aggregates, where this sign is negative, the interference is constructive instead; as a result, no such coherent suppression of the annihilation rate occurs. As a consequence, room temperature annihilation rates of typical H- and J-aggregates differ by a factor of ~3, while an order of magnitude difference is found for low-temperature aggregates with a low degree of disorder. These findings, which explain experimental observations, reveal a fundamental principle underlying exciton-exciton annihilation, with major implications for technological devices and experimental studies involving high excitation densities. PMID- 29190422 TI - Structure-Specific Effects of Short-Chain Fatty Acids on Plasma Cholesterol Concentration in Male Syrian Hamsters. AB - Previous studies have shown that short-chain fatty acids (SCFAs) are capable of decreasing plasma cholesterol. However, the relative plasma-cholesterol-lowering activity of individual SCFAs and the underlying mechanisms by which SCFAs decrease plasma cholesterol remain largely unknown. The present study was done to compare the plasma-cholesterol-lowering potencies of four common SCFAs with 2-5 carbons and to investigate their interactions with gene expressions of key regulatory factors involved in cholesterol metabolism. For 6 weeks, five groups of male Golden hamsters were fed either a control high-cholesterol diet (HCD) or one of the four experimental HCDs containing 0.5 mol of acetate (Ac), propionate (Pr), butyrate (Bu), or valerate (Va) per kilogram of the diet. The results showed that Ac, Pr, and Bu significantly reduced plasma total cholesterol (TC) by 24, 18, and 17% (P < 0.05), respectively. All four SCFAs could decrease non-HDL cholesterol (non-HDL-C) and the non-HDL-C/HDL-C ratio. The addition of Ac, Pr, or Bu into the diet significantly promoted fecal excretion of bile acids by 121, 113, or 120% (P < 0.05), respectively, and upregulated the gene expressions of sterol-regulatory-element-binding protein 2 (SREBP2), low-density-lipoprotein receptor (LDLR), and cholesterol 7alpha-hydroxylase (CYP7A1) in the liver. It was concluded that SCFAs with 2-4 carbons (Ac, Pr, and Bu) are more hypocholesterolemic than Va, which has 5 carbons, via enhancing fecal excretion of bile acids and promoting the hepatic uptake of cholesterol from the blood. PMID- 29190423 TI - Modeling the CH Stretch/Torsion/Rotation Couplings in Methyl Peroxy (CH3OO). AB - The manifestations of CH stretch/torsion/rotation coupling in the region of the CH stretch fundamentals are explored in the CH3OO radical. Following our earlier study of the fundamental in the totally symmetric CH stretch (the nu2 fundamental), this work focuses on the other two CH stretch fundamentals, nu1 and nu9, which would be degenerate in the absence of a barrier in the potential along the methyl torsion coordinate. The simplest model, which assumes a decoupling of the CH stretch vibrations from the torsion, fails to reproduce several important features of the spectrum. Specifically, the absence of a strong peak around the origin of the nu1 fundamental and broadening of the strong peak near the origin in the observed spectrum of the nu9 fundamental are not captured by this model. The origins of these features are explored through two more sophisticated treatments of the torsion/CH stretch couplings. In the first, a four-dimensional potential based on the three CH stretches and the torsion is developed and shown to reproduce both of these features. On the basis of the results of these calculations, the calculated parameters are adjusted to simulate the recorded spectrum. To further explore the torsion/CH stretch couplings in CH3OO, a 9-state model Hamiltonian is developed and discussed. The implications of various types of couplings on the observed energy level patterns are also discussed. PMID- 29190424 TI - Understanding How Nitriles Stabilize Electrolyte/Electrode Interface at High Voltage. AB - Nitriles have received extensive attention for their unique ability in stabilizing electrolytes against oxidation at high voltages. It was generally believed that their anodic stability originates from a monolayer of chemisorbed nitrile molecules on transition-metal oxide surface, which physically expels carbonate molecules and prevents their oxidative decomposition. We overturn this belief based on calculation and experimental results and demonstrate that, like many high voltage film-forming electrolyte additives, nitriles also experience an oxidative decomposition at high voltages, and the high oxidation stability of nitrile-containing electrolytes is merely the consequence of a new interphasial chemistry. This important mechanistic correction would be of high significance in guiding the design of new electrolytes and interphases for the future battery chemistries. PMID- 29190425 TI - The Effects of Shear Force Transmission Across Vesicle Membranes. AB - We report a comprehensive study on mechanotransmission of shear forces across lipid bilayer membranes of giant unilamellar vesicles (GUVs). GUVs containing fluorescent tracer particles were immobilized on a microfluidic platform and exposed to shear flows. A method was developed for the visualization of three dimensional flows at high precision by defocusing microscopy. We quantify the symmetry of external flow around the GUV and show its effects on vortex flows and luminal dynamics. With increasing asymmetry, luminal vortices merged while liquid exchange in between them increased. The effect of membrane composition was studied through addition of cholesterol. Mechanotransmission efficacy, quantified by the ratio of luminal flow to external flow, ranged from epsilon = 0.094 (0 mol % cholesterol) to epsilon = 0.043 (16 mol % cholesterol). Our findings give new cues to the mechanisms underlying the sensing of strength and spatial distribution of shear forces by cells and the impact of membrane composition.

AB - Ameliorations of cholinergic system dysfunction and oxidative stress in neurodegenerative diseases were main approaches to improve memory disorder. Our previous investigation showed that anchovy protein hydrolysate (APH) could attenuate scopolamine-induced memory deficits in mice by regulating acetylcholinesterase (AChE) activity. Therefore, peptides with AChE inhibitory activity in APH were explored and identified in this study, and their possible neuroprotective mechanisms on glutamate induced apoptosis in PC12 were also elucidated. Two peptides with strong AChE inhibitory capacity were identified as Pro-Ala-Tyr-Cys-Ser (PAYCS) and Cys-Val-Gly-Ser-Tyr (CVGSY) by ultraperformance liquid chromatography coupled with tandem mass spectrometry. The AChE inhibitory was 23.68 +/- 0.97% and 6.08 +/- 0.41%, respectively. Treatment with PAYCS and CVGSY could significantly (p < 0.05) increase cells viability, reduce lactate dehydrogenase release, reactive oxygen species (ROS) production, malondialdehyde content, and the ratio of Bax/Bcl-2 of glutamate-induced apoptosis PC12 cells (82.78 +/- 6.58 and 109.94 +/- 7.16% of control, respectively) as well as increase superoxide dismutase and GSH-px activities. In addition, both the peptides could inhibit Ca2+ influx but have no effects on mitochondrial membrane potential. Results indicated that AChE inhibitory peptides (PAYCS and CVGSY) possibly protected the PC12 cells against glutamate-induced apoptosis via inhibiting ROS production and Ca2+ influx. PAYCS and CVGSY might be considered as nutraceuticals for alleviating memory deficits. PMID- 29190427 TI - Controlling Long-Lived Triplet Generation from Intramolecular Singlet Fission in the Solid State. AB - The conjugated polymer poly(benzothiophene dioxide) (PBTDO1) has recently been shown to exhibit efficient intramolecular singlet fission in solution. We investigate the role of intermolecular interactions in triplet separation dynamics after singlet fission. We use transient absorption spectroscopy to determine the singlet fission rate and triplet yield in two polymers differing only by side-chain motif in both solution and the solid state. Whereas solid state films show singlet fission rates identical to those measured in solution, the average lifetime of the triplet population increases dramatically and is strongly dependent on side-chain identity. These results show that it may be necessary to carefully engineer the solid-state microstructure of these "singlet fission polymers" to produce the long-lived triplets needed to realize efficient photovoltaic devices.

AB - Defining the mechanisms of cellular pathogenesis in rare lung diseases such as Hermansky-Pudlak syndrome (HPS) is often complicated by loss of the differentiated phenotype of cultured primary alveolar type 2 (AT2) cells, as well as by a lack of durable cell lines that are faithful to both AT2-cell and rare disease phenotypes. We used CRISPR/Cas9 gene editing to generate a series of HPS specific mutations in the MLE-15 cell line. The resulting MLE-15/HPS cell lines exhibit preservation of AT2 cellular functions, including formation of lamellar body-like organelles, complete processing of surfactant protein B, and known features of HPS specific to each trafficking complex, including loss of protein targeting to lamellar bodies. MLE-15/HPS1 and MLE-15/HPS2 (with a mutation in Ap3beta1) express increased macrophage chemotactic protein-1, a well-described mediator of alveolitis in patients with HPS and in mouse models. We show that MLE 15/HPS9 and pallid AT2 cells (with a mutation in Bloc1s6) also express increased macrophage chemotactic protein-1, suggesting that mice and humans with BLOC-1 mutations may also be susceptible to alveolitis. In addition to providing a flexible platform to examine the role of HPS-specific mutations in trafficking AT2 cells, MLE-15/HPS cell lines provide a durable resource for high-throughput screening and studies of cellular pathophysiology that are likely to accelerate progress toward developing novel therapies for this rare lung disease. PMID- 29190430 TI - Evaluating UK National Guidance for Screening of Children for Tuberculosis. A Prospective Multicenter Study. AB - RATIONALE: To identify infected contacts of tuberculosis (TB) cases, the UK National Institute for Health and Care Excellence (NICE) recommended the addition of IFN-gamma release assays (IGRA) to the tuberculin skin test (TST) in its 2006 TB guidelines. Treatment for TB infection was no longer recommended for children who screened TST-positive but IGRA-negative. OBJECTIVES: We performed a cohort study to evaluate the risk of TB disease in this group. METHODS: Children exposed to an infectious case of TB in their household were recruited from 11 pediatric TB clinics. TST and IGRA were performed at baseline, with IGRA repeated at 8 weeks and TST repeated if initially negative. Children were treated according to 2006 NICE guidelines and followed for 24 months. MEASUREMENTS AND MAIN RESULTS: Of 431 recruited children, 392 completed the study. We diagnosed 48 (12.2%) cases of prevalent TB disease, 105 (26.8%) with TB infection, and 239 (60.9%) without TB infection or disease. Eighteen children aged 2 years and above had a positive TST but persistently negative IGRA. None received TB infection treatment and none developed TB disease. Ninety (26.1%) children qualified for TB infection treatment according to 2006 NICE guidelines. In contrast, 147 (42.7%) children would have qualified under revised NICE guidance, issued in 2016. CONCLUSIONS: In this low-prevalence setting we saw no incident cases of TB disease in children who were TST-positive but IGRA-negative and did not receive treatment for TB infection. Following the latest NICE guidance, significantly more children will require medication. PMID- 29190443 TI - Corrigendum to: It's more than money: policy options to secure medical specialist workforce for regional centres. AB - Objectives Regional centres and their rural hinterlands support significant populations of non-metropolitan Australians. Despite their importance in the settlement hierarchy and the key medical services provided from these centres, little research has focused on their issues of workforce supply and long-term service requirements. In addition, they are a critical component of the recent growth of 'regional' hub-and-spoke specialist models of service delivery.Methods The present study interviewed 62 resident specialists in four regional centres, seeking to explore recruitment and retention factors important to their location decision making. The findings were used to develop a framework of possible evidence-informed policies.Results This article identifies key professional, social and locational factors, several of which are modifiable and amenable to policy redesign, including work variety, workplace culture, sense of community and spousal employment; these factors that can be targeted through initiatives in selection, training and incentives.Conclusions Commonwealth, state and local governments in collaboration with communities and specialist colleges can work synergistically, with a multiplicity of interdigitating strategies, to ensure a positive approach to the maintenance of a critical mass of long-term rural specialists.What is known about the topic? Rural origin increases likelihood of long-term retention to rural locations, with rural clinical school training associated with increased rural intent. Recruitment and retention policy has been directed at general practitioners in rural communities, with little focus on regional centres or medical specialists.What does this study add? Rural origin is associated with regional centre recruitment. Professional, social and locational factors are all moderately important in both recruitment and retention. Specialist medical training for regional centres ideally requires both generalist and subspecialist skills sets. Workforce policy needs to address modifiable factors with four groups, namely commonwealth and state governments, specialist medical colleges and local communities, all needing to align their activities for achievement of long-term medical workforce outcomes.What are the implications for practitioners? Modifiable factors affecting recruitment and retention must be addressed to support specialist models of care in regional centres. Modifiable factors relate to maintenance of a critical mass of practitioners, training a fit for-purpose workforce and coordinated effort between stakeholders. Although remuneration is important, the decision to stay relates primarily to non financial factors.

AB - Thirteen compounds were isolated from the aerial parts of Hypericum kelleri Bald., growing as an endemic on the island of Crete (Greece). These compounds comprise four previously unknown prenylated xanthones 1,2-dihydro-3,8-dihydroxy-6 methoxy-1,1,5-tri(3-methylbut-2-enyl)xanthen-2,9-dione (kellerine A), 1,2-dihydro 3,6,8-trihydroxy-1,1,5-tri(3-methylbut-2-enyl)xanthen-2,9-dione (kellerine B), 1,2-dihydro-3,8-dihydroxy-6-methoxy-1,1-bi(3-methylbut-2-enyl)xanthen-2,9-dione (6-methylpatulone), (R/S)-1,3,5-trihydroxy-2-(3-methyl-2-buten-1-yl)-4-[2-(3 methylbut-2-enyl)-3-methylbut-3-enyl]-6-methoxy-9H-xanthen-9-one ((2"R/S) kellerine C) and the hitherto undescribed depsidone (R/S)-1,3,6-trihydroxy-5 methoxy-2-(3-methyl-2-buten-1-yl)-4-[2-(3-methylbut-2-enyl)-3-methylbut-3-enyl] 11Eta-dibenzo[b,e] [1,4]dioxepin-9-one ((2"R/S)-creticine). As known compounds, brevipsidone D, 4-geranyl-2-(2'-isobutyryl)-phloroglucinol, 4-geranyl-2-(2' methylbutyryl)-phloroglucinol, I3, II8-biapigenin, quercetin, avicularin, pseudohypericin and neochlorogenic acid have been isolated. The structures were elucidated on the basis of their 1D, 2D NMR, CD and MS data. The study confirms the typical occurrence of xanthones in Hypericum section Oligostema (Boiss.) Stef., and is also the first report on the simultaneous isolation of acylphloroglucinols in this section. Furthermore the first evidence of depsidones in the genus Hypericum L. is reported. Cytotoxicity was investigated in HeLa cells for prenylated xanthones and the depsidones. Both triprenylated 1,2 dihydroxanthones (kellerine A and B) showed significant in vitro cytotoxicity with IC50 values of 2.5 +/- 0.1 (kellerine A) and 5.9 +/- 0.9 (kellerine B) MUM, whereas other compounds were less cytotoxic (IC50 > 20 MUM).

AB - Glossina palipides salivary gland hypertrophy virus (GpSGHV) infects tsetse flies, which are vectors for African trypanosomosis. This virus represents a major challenge in insect mass rearing and has hampered the implementation of the sterile insect technique programs in the Member States of the International Atomic Energy Agency. GpSGHV virions consist of long rod-shaped particles over 9000A in length, but little is known about their detailed structural organization. We show by cryo electron microscopy and cryo electron tomography that the GpSGHV virion has a unique, non-icosahedral helical structure. Its envelope exhibits regularly spaced spikes that protrude from the lipid bilayer and are arranged on a four-start helix. This study provides a detailed insight into the 3D architecture of GpSGHV, which will help to understand the viral life cycle and possibly allow the design of antiviral strategies in the context of tsetse fly infections.

AB - OBJECTIVE: Enamel structure reflects ameloblast function. By studying the structure of the superficial enamel, information about ameloblast function toward the end of the secretory stage may be obtained. DESIGN: The superficial enamel in midcoronal areas of acid-etched facio-lingual sections from human third molars was studied in the scanning electron microscope (SEM). RESULTS: A great variation was observed in occurrence of prism-free enamel. Prism-free enamel dominated in 40% (mandibular) and 47% (maxillary) of observed areas and had a mean thickness of about 30MUm. Striations in the prism-free enamel had an interstriae distance of about 3.3-3.8MUm. The angle between prisms and enamel surface was about 60 degrees , between prisms and Retzius lines about 45 degrees and between Retzius lines and enamel surface about 15 degrees . The distances between regularly occurring Retzius lines and between striations in the prism-free enamel both tended to decrease toward the enamel surface. Prisms could change direction as they approached the enamel surface, mostly in cervical direction. Where Retzius lines curved and converged occlusally, prisms tended to deviate in an occlusal direction. CONCLUSIONS: Judged from the incremental lines and occurrence of prism free enamel, ameloblasts slow down and tend to lose their Tomes' process as they approach the end of secretion. The crystals of prism-free enamel belong to the same system as the interprism crystals of prismatic enamel. A method, based on the disposition of fine incremental lines, is suggested for evaluation of ameloblast dynamics in the last stage of enamel secretion. PMID- 29190457 TI - The influence of the number of toys in the environment on toddlers' play. AB - We tested the hypothesis that an environment with fewer toys will lead to higher quality of play for toddlers. Each participant (n=36) engaged in supervised, individual free play sessions under two conditions: Four Toy and Sixteen Toy. With fewer toys, participants had fewer incidences of toy play, longer durations of toy play, and played with toys in a greater variety of ways (Z=-4.448, p<0.001, r=-0.524; Z=2.828, p=0.005, r=0.333; and Z=4.676, p<0.001, r=0.55, respectively). This suggests that when provided with fewer toys in the environment, toddlers engage in longer periods of play with a single toy, allowing better focus to explore and play more creatively. This can be offered as a recommendation in many natural environments to support children's development and promote healthy play.

AB - INTRODUCTION: Older adults, including those with mild cognitive impairment (MCI), are increasingly undergoing surgery. METHODS: Relative risks (RRs) of MCI alone or with delirium on adverse outcomes were estimated in an ongoing prospective, observational cohort study of 560 nondemented adults aged >=70 years. RESULTS: MCI (n = 61, 11%) was associated with increased RR of delirium (RR = 1.9, P < .001) and delirium severity (RR = 4.6, P < .001). Delirium alone (n = 107), but not MCI alone (n = 34), was associated with multiple adverse outcomes including more major postoperative complication(s) (RR = 2.5, P = .002) and longer length of stay (RR = 2.2, P < .001). Patients with concurrent MCI and delirium (n = 27) were more often discharged to a postacute facility (RR = 1.4, P < .001) and had synergistically increased risk for new impairments in cognitive functioning (RR = 3.6, P < .001). DISCUSSION: MCI is associated with increased risk of delirium incidence and severity. Patients with delirium and MCI have synergistically elevated risk of developing new difficulties in cognitively demanding tasks.

AB - Due to the excessive use of antibiotics over the years, the microorganisms have developed resistance to numerous drugs. The growth of multi-resistant organisms (MROs) heads due to the insufficient treatment with the currently available medications which present a great threat to the biotic component of the environment as well as to the food technology sectors. The goal of this research was to develop a nano-composite made up of single-walled carbon nanotubes (SWCNTs) and amine-functionalized porphyrin, which could further be used for the anti-microbial studies in presence of visible light showing photodynamic effect to inactivate cells. Photodynamic antimicrobial chemotherapy is gaining significant interest due to its capabilities as an innovative form of antimicrobial treatment. The development of anti-microbial photodynamic therapy (a-PDT) is a non-antibiotic access to inactivate microorganisms. We examined the synthesis of amine-functionalized porphyrin and conjugated it to the oxidised single-walled carbon nanotubes (SWCNTs). By the use of appropriate amount of single-walled carbon nanotubes (SWCNTs), we have shown the interaction between the porphyrin conjugated nanotubes and the bacterial cells in presence of visible light led to the cell membrane damage, concluding that SWCNT-porphyrin conjugates can be used as an antibacterial agent. The characterization of the oxidised SWCNT and SWCNT-porphyrin conjugates was determined by field emission scanning electron microscopy (FE-SEM), which provides detailed information about the composition and the morphological analysis. The particle size measurements were carried out by transmission electron microscopy (TEM). On investigating under the florescence microscopy, red fluorescence was observed. Thus, these properties demand us to design this facile material comprised of SWCNT-aminoporphyrin conjugates that shows potent antibacterial activity.

AB - In this paper, the colorimetric sensing of H2O2 related molecules and biothiols based on etching and anti-etching strategy was firstly proposed. Ag/carbon nanocomposite (Ag/C NC) was served as the sensing nanoprobe, which was synthesized via carbon dots (C-dots) as the reductant and stabilizer. The characteristic surface plasmon resonance (SPR) absorbance of Ag nanoparticles (AgNPs) was sensitive to the amount of hydrogen peroxide (H2O2). It exhibited strong optical responses to H2O2 with the solution colour changing from yellow to nearly colourless, which is resulted from the etching of Ag by H2O2. The sensing platform was further extended to detect H2O2 related molecules such as lactate in coupling with the specific catalysis oxidation of L-lactate by lactate oxidase (LOx) and formation of H2O2. It provides wide linear range for detecting H2O2 in 0.1-80MUM and 80-220MUM with the detection limit as low as 0.03MUM (S/N=3). In the presence of biothiols, the etching from the H2O2 can be hampered. Other biothiols exhibit anti-etching effects well. The strategy works well in detecting of typical biothiols including cysteine (Cys), homocysteine (Hcy) and glutathione (GSH). Thus, a simple colorimetric strategy for sensitive detection of H2O2 and biothiols is proposed. It is believed that the colorimetric sensor based on etching and anti-etching strategy can be applied in other systems in chemical and biosensing areas.

AB - Schwann cell-seeded nerve guidance channels are designed to assist post-traumatic nerve regeneration in the PNS. Chitosan is a natural polymer well suited for tissue engineering as it is biocompatible, non-immunogenic, and biodegradable. Electrospun chitosan nanofibers utilized in nerve guidance channels have the capacity for guiding axonal growth within the channel lumen yet are limited in their capacity to maintain structural integrity within physiological environments. To address this, we attempted genipin crosslinking of chitosan nanofibers. Compared to neat chitosan nanofibers, genipin-treated nanofibers exhibited increased stiffness, resistance to swelling and lysozymal degradation. Furthermore, alignment and proliferation of purified Schwann cell cultures upon genipin-treated substratum was enhanced. When dorsal root ganglion explants were utilized as an in vitro model of peripheral nerve regeneration, emigrating neurons and Schwann cells assumed the uniaxial pattern of aligned electrospun chitosan nanofibers. Neurite growth along the nanofibers led, reaching a frontier more than twice that of the pursuant Schwann cells. Critically, neurite growth rate upon genipin-treated nanofibers demonstrated a 100% increase. Altogether, genipin treatment improves upon the physical and biological properties of chitosan nanofibers towards their utility in nerve guidance channel design.

AB - We developed a facile one-pot fabrication process for magnetic iron oxide-calcium phosphate (IO-CaP) composite nanoparticles via coprecipitation in labile supersaturated CaP solutions containing IO nanocrystals. All the source solutions used were clinically approved for injection, including water and magnetic IO nanocrystals (ferucarbotran, used as a negative magnetic resonance imaging (MRI) contrast agent). This ensured that the resulting nanoparticles were pathogen- and endotoxin-free. The dispersants used were clinically approved heparin sodium (heparin) or adenosine triphosphate disodium hydrate (ATP), which were added to the IO-containing labile supersaturated CaP solutions. Both heparin and ATP coprecipitated with CaP and ferucarbotran to form heparin- and ATP-modified IO CaP nanoparticles, respectively, with a hydrodynamic diameter of a few hundred nanometers. Both the resulting nanoparticles exhibited relatively large negative zeta potentials, caused by the negatively charged functional groups in heparin and ATP, which improved the particle dispersibility when compared to non-modified IO-CaP nanoparticles. The heparin-modified IO-CaP nanoparticles were effectively ingested by murine macrophages (RAW264.7) without showing significant cytotoxicity but barely ingested by non-phagocytotic human umbilical vein endothelial cells, indicating the potential of these nanoparticles for targeted delivery to macrophages. The heparin-modified IO-CaP nanoparticles exhibited a negative contrast enhancing ability for MRI. Our results show that IO-CaP nanoparticles have potential as delivery and MRI contrast agents for macrophages.

AB - Boronate affinity chromatography is a common purification method used for isolation and purification of cis-diol containing biomolecules. Poly (hydroxyethyl methacrylate-co-vinyl phenyl boronic acid) [P(HEMA-VPBA)] nanoparticles were prepared by miniemulsion polymerization to use in RNA purification methods. The P(HEMA-VPBA) nanoparticles were characterized by particle size distribution, surface area, Fourier transform infrared spectroscopy and atomic force microscopy. The effects of temperature, pH, RNA concentration and different salt types on RNA binding on the P(HEMA-VPBA) nanoparticles were examined. It was observed that RNA binding was increased with the increasing of pH and max RNA binding was obtained at pH 9.0. RNA binding capacity of the P(HEMA VPBA) nanoparticles was increased from 167mg/g to 601mg/g with addition of BaCl2 to the binding medium. Maximum RNA binding capacity of the P(HEMA-VPBA) nanoparticles was 172mg/g at 1.0mg/mL initial RNA concentration. The P(HEMA-VPBA) nanoparticles were reusable for RNA binding. RNA was also extracted from Escherichia coli cells and purified successfully using the P(HEMA-VPBA) nanoparticles. PMID- 29190466 TI - Thermo-responsive molecularly imprinted polymer containing magnetic nanoparticles: Synthesis, characterization and adsorption properties for curcumin. AB - A novel intelligent thermoresponsive-magnetic molecularly imprinted polymer (TMMIP) nanocomposite based on N-isopropylacrylamide (NIPAM) & Fe3O4 was designed for the controlled & sustained release of Curcumin (CUR) with the ability to response external stimulus. The TMMIP nanocomposite was prepared using acryl functionalized beta-cyclodextrin (beta-CD) and NIPAM as functional monomers and CUR as target molecule. The recognition cavities which caused by host-guest interactions had direct influence to enhanced drug loading and sustained release of CUR. According to in-vitro release experiment in two different temperatures (below & above LCST of NIPAM) the prolonged & controlled release of CUR were observed. The release rate could be controlled by changing the temperature because of the phase transition behavior of NIPAM monomer. Also, the proposed biosensor displayed effective role in separation science, reasonable adsorption capacity (77mgg-1), fast recognition (10min equilibration), selective extraction toward CUR in the presence of structural analogues and easily separation using external magnetic field. Moreover, the synthesized TMMIP was confirmed by various characterization. PMID- 29190467 TI - pH sensitive surfactant-stabilized Fe3O4 magnetic nanocarriers for dual drug delivery. AB - Highly water-dispersible surfactant-stabilized Fe3O4 magnetic nanocarriers (SMNCs) were prepared by self-assembly of anionic surfactant, sodium dodecyl sulphate (SDS) on hydrophobic (oleic acid coated) nanoparticles and their biomedical applications were investigated. These nanocarriers have an average size of about 10nm and possess tunable surface charge properties. The formation of an organic coating of SDS was evident from infrared spectroscopy, dynamic light scattering, zeta-potential and thermogravimetric measurements. These nanocarriers were used for loading of both hydrophilic and hydrophobic anticancer agents such as doxorubicin hydrochloride (DOX) and curcumin (CUR), respectively. DOX was conjugated onto the surface of nanocarriers through electrostatic interaction, whereas CUR was encapsulated into the hydrophobic interlayer between oleic acid and SDS. The toxicity and cellular internalization of drug loaded nanocarriers were investigated against WEHI-164 cancer cell line. Specifically, the drug loading, pH sensitive drug release and cellular internalization studies suggested that these nanocarriers are suitable for dual drug delivery. Furthermore, they show good heating ability under AC magnetic field, thus can be used as effective heating source for hyperthermia treatment of cancer. PMID- 29190468 TI - Selenoprotein L-inspired nano-vesicular peroxidase mimics based on amphiphilic diselenides. AB - In this study, we developed selenoprotein L-inspired nano-vesicular peroxidase mimics based on amphiphilic diselenides. Selenocystine (SeCyst) was used as the starting material for the synthesis of four liposomal membrane-compatible diselenide derivatives (R-Se-Se-R') with two hydrophobic tails and a polar part. The diselenide derivatives were successfully incorporated into the phosphatidylcholine (PC)-based nano-vesicular scaffold. The results of the particle diameter and zeta-potential measurements suggested that the functional diselenide moiety was placed around the outer surface, not in the hydrophobic interior, of the liposomal membrane structures. The GPx-like catalytic activity of the diselenide/PC liposomes was determined by the conventional NADPH method using glutathione as the reducing substrate. For three peroxide substrates, i.e., hydrogen peroxide, organic tert-butyl hydroperoxide and cummen hydroperoxide, the cationic property-possessing diselenide derivatives in the PC-based liposomes resulted in a higher catalytic activity in comparison to electrically neutral and anionic derivatives. Overall, the diselenide derivatives at the surface of a liposomal colloidal scaffold could exert a GPx-like catalytic activity in physiological aqueous media. PMID- 29190469 TI - Effects of solution chemistry on the sunlight inactivation of particles associated viruses MS2. AB - The inactivation efficacy of bacteriophage MS2 by simulated sunlight irradiation was investigated to understand the effects of MS2 aggregation and adsorption to particles in solutions with different components. Kaolinite and Microcystis aeruginosa were used as model inorganic and organic particles, respectively. Lower pH and di-valent ions (Ca2+) were main factors on the aggregation and inactivation of MS2. In the presence of both particles, there was no significant impact on the MS2 inactivation efficacy by kaolinite (10-200mM) or Microcystis aeruginosa (102-105Cells/mL) in 1mM NaCl at pH 7. However at lower pH 3, MS2 aggregates formed in the particle-free and kaolinite-containing solutions, caused lower inactivation since the outer viruses of aggregation protect the inner viruses. In addition, more MS2 adsorbed on Microcystis aeruginosa at lower pH (3 and 4). Microcystis aeruginosa would act as a potential photosensitizer for ROS production to inactivate the adsorbed MS2, since extracellular organic matter (EOM) of Microcystis aeruginosa was detected in this study, which has been reported to produce ROS under solar irradiation. At pH 7, Na+ had no effect on the inactivation of MS2, because MS2 was stable and dispersed even at 200mM Na+. MS2 aggregated and adsorbed on particles even at 10mM Ca2+ and led to lower inactivation. Kaolinite cannot offer enough protection to adsorbed MS2 as aggregation and Microcystis aeruginosa acts as potential photosensitizer to produce ROS and inactivate the adsorbed MS2 at high concentration of Ca2+. In particle-free solution, SRNOM inhibited MS2 inactivation by shielding the sunlight and coating MS2 to increase its survival. PMID- 29190470 TI - Negatively charged polypeptide-peptide nanoparticles showing efficient drug delivery to the mitochondria. AB - Polymeric nanoparticles (NPs) represent an effective platform for drug delivery systems, albeit with various limitations including low drug loading capacity, cytotoxicity and specificity. NPs composed of the negatively charged Polypeptide, poly gamma glutamic acid (gamma-PGA) and a designed amphiphilic and cationic beta sheet Peptide (denoted PoP-NPs) loaded with the drug lonidamine (LND), denoted LND-PoP-NPs were previously used in our lab to successfully target the mitochondria when coated with the peptide (LND-mPoP-NPs). In this study, we improved the drug capacity of the LND-mPoP-NPs in addition to lowering non specific toxicity associated with the drug deficient mPoP-NPs. LND concentrations in LND-mPoP-NPs were increased (h-LND-mPoP-NPs) and the peptide coating concentration was decreased. The new h-LND-mPoP-NPs formulation shows the ability to carry the drug to the proximity of the mitochondria despite the NP's negative zeta potential. PMID- 29190471 TI - Influence of shape and dispersion media of titanium dioxide nanostructures on microvessel network and ossification. AB - Titanium dioxide nanoparticles (TiO2 NPs) production has been used for pigment, food and cosmetic industry and more recently, shaped as belts for treatment of contaminated water, self-cleaning windows and biomedical applications. However, the toxicological data have demonstrated that TiO2 NPs inhalation induce inflammation in in vivo models and in vitro exposure leads to cytotoxicity and DNA damage. Dermal exposure has limited adverse effects and the possible risks for implants used for tissue regeneration is still under research. Then, it has been difficult to establish a straight statement about TiO2 NPs toxicity since route of exposure and shapes of nanoparticles play an important role in the effects. In this study we aimed to investigate the effect of three different types of TiO2 NPs (industrial, food-grade and belts) dispersed in fetal bovine serum (FBS) and saline solution (SS) on microvessel network, angiogenesis gene expression and femur ossification using a chick embryo model after an acute exposure of NPs on the day 7 after eggs fertilization. Microvascular density of chorioallantoic membrane (CAM) was analyzed after 7days of NPs injection and vehicles induced biological effects per se. NPs dispersed in FBS or SS have slight differences in microvascular density, mainly opposite effect on angiogenesis gene expression and no effects on femur ossification for NPs dispersed in SS. Interestingly, NPs shaped as belts dramatically prevented the alterations in ossification induced by FBS used as vehicle. PMID- 29190472 TI - A fluorescent sensor for detecting dopamine and tyrosinase activity by dual emission carbon dots and gold nanoparticles. AB - In this work, we report a fluorescence strategy for detecting dopamine (DA) and sensing tyrosinase (TYR) activity on the basis of the dual-emission carbon dots (DECDs), which contain two emitters: the blue emitters (BE, maximum emission at 385nm) and yellow emitters (YE, maximum emission at 530nm). Gold nanoparticles (AuNPs) can effectively quench the two emissions of DECDs. The addition of DA aggregates AuNPs effectively, leading to the fluorescence recovery of dual emitters gradually. This strategy exhibits a high selectivity toward DA and shows good linear ranges, such as 0.5-3MUM for BE and 0.1-3MUM for YE. Additionally, the proposed method is successfully applied to the determination of DA in real samples with satisfactory recoveries. Subsequently, this DECDs-AuNPs platform is further taken advantage to assess TYR activity by the aid of TYR's capability for oxidation of DA into dopaquinone, which will not induce the agglomeration of AuNPs, so the fluorescence quenching of DECDs is associated with TYR activity. Finally, the mechanism of the reaction is discussed in detail, and the results suggest that both amine and phenolic hydroxyl groups of DA bring the aggregation of AuNPs. PMID- 29190473 TI - Participation of copper ions in formation of alginate conditioning layer: Evolved structure and regulated microbial adhesion. AB - Antifouling function of copper-based layers is usually gained through the release of cuprous or copper ions to damage most fouling species. In this research the intervening mechanisms of copper ions in formation of simplified conditioning layer comprising marine polysaccharide alginate and subsequent adhesion of typical marine bacteria and algae were studied. Fast interaction of Cu2+ with alginate with the formation of copper alginate multimers was observed for the first time by negative-staining electron microscopy. Interconnecting chains of alginate and copper alginate upon adsorption on silicon wafer and tangled structure of the conditioning layer were further characterized by atomic force microscopy. Adhesion testing showed that consumption of copper ions by their linking with alginate in incubation solutions resulted in mitigated toxicity of the ions to the microorganisms Bacillus sp., Chlorella pyrenoidosa and Phaeodactylum tricornutum. The results would give insight into understanding and regulating the formation of conditioning layer for desired antifouling performances. PMID- 29190474 TI - Functional Micrococcus lysodeikticus layers deposited by laser technique for the optical sensing of lysozyme. AB - Whole cell optical biosensors, made by immobilizing whole algal, bacterial or mammalian cells on various supports have found applications in several fields, from ecology and ecotoxicity testing to biopharmaceutical production or medical diagnostics. We hereby report the deposition of functional bacterial layers of Micrococcus lysodeikticus (ML) via Matrix-Assisted Pulsed Laser Evaporation (MAPLE) on poly(diallyldimethylamonium) (PDDA)-coated-glass slides and their application as an optical biosensor for the detection of lysozyme in serum. Lysozyme is an enzyme upregulated in inflammatory diseases and ML is an enzymatic substrate for this enzyme. The MAPLE-deposited bacterial interfaces were characterised by Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Fourier-Transformed Infrared Spectroscopy (FTIR), Raman and optical microscopy and were compared with control interfaces deposited via layer-by-layer on the same substrate. After MAPLE deposition and coating with graphene oxide (GO), ML-modified interfaces retained their functionality and sensitivity to lysozyme's lytic action. The optical biosensor detected lysozyme in undiluted serum in the clinically relevant range up to 10MUgmL-1, in a fast and simple manner. PMID- 29190475 TI - Discovery of microRNAs associated with the antiviral immune response of Atlantic cod macrophages. AB - MicroRNAs (miRNAs) are known to play important immunoregulatory roles in teleosts, although miRNAs involved in the antiviral immune response of Atlantic cod (Gadus morhua) were previously uncharacterised. Using deep sequencing and qPCR, the present study was conducted to identify miRNAs responsive to the viral mimic, polyriboinosinic polyribocytidylic acid (pIC) in Atlantic cod macrophages. Macrophage samples isolated from Atlantic cod (n=3) and treated with pIC or phosphate buffered saline (PBS control) for 24 and 72h were used for miRNA profiling. Following deep sequencing, DESeq2 analyses identified four (miR-731 3p, miR-125b-3-3p, miR-150-3p and miR-462-3p) and two (miR-2188-3p and miR-462 3p) significantly differentially expressed miRNAs at 24 and 72h post-stimulation (HPS), respectively. Sequencing-identified miRNAs were subjected to qPCR validation using a larger number of biological replicates (n=6) exposed to pIC or PBS over time (i.e. 12, 24, 48 and 72 HPS). As in sequencing, miR-731-3p, miR-462 3p and miR-2188-3p showed significant up-regulation by pIC. The sequencing results were not qPCR-validated for miR-125b-3-3p and miR-150-3p as up- and down regulated miRNAs at 24 HPS, respectively; however, qPCR results showed significant up-regulation in response to pIC stimulation at later time points (i.e. 48 and/or 72 HPS). We also used qPCR to assess the expression of other miRNAs that were previously shown as immune responsive in other vertebrates. qPCR results at 48 and/or 72 HPS revealed that miR-128-3-5p, miR-214-1-5p and miR-451 3p were induced by pIC, whereas miR-30b-3p and miR-199-1-3p expression were repressed in response to pIC. The present study identified ten pIC-stimulated miRNAs, suggesting them as important in antiviral immune responses of Atlantic cod macrophages. Some pIC-responsive miRNAs identified in this study were predicted to target putative immune-related genes of Atlantic cod (e.g. miR-30b 3p targeting herc4), although the regulatory functions of these miRNAs need to be validated by future studies. PMID- 29190476 TI - The "Janus face" of the thrombin binding aptamer: Investigating the anticoagulant and antiproliferative properties through straightforward chemical modifications. AB - BACKGROUND: The thrombin binding aptamer (TBA) is endowed with both anticoagulant and antiproliferative activities. Its chemico-physical and/or biological properties can be tuned by the site-specific replacement of selected residues. METHODS: Four oligodeoxynucleotides (ODNs) based on the TBA sequence (5' GGTTGGTGTGGTTGG-3') and containing 2'-deoxyuridine (U) or 5-bromo-2'-deoxyuridine (B) residues at positions 4 or 13 have been investigated by NMR and CD techniques. Furthermore, their anticoagulant (PT assay) and antiproliferative properties (MTT assay) have been tested and compared with two further ODNs containing 5-hydroxymethyl-2'-deoxyuridine (H) residues in the same positions, previously investigated. RESULTS: The CD and NMR data suggest that all the investigated ODNs are able to form G-quadruplexes strictly resembling that of TBA. The introduction of B residues in positions 4 or 13 increases the melting temperature of the modified aptamers by 7 degrees C. The replacement of thymidines with U in the same positions results in an enhanced anticoagulant activity compared to TBA, also at low ODN concentration. Although all ODNs show antiproliferative properties, only TBA derivatives containing H in the positions 4 and 13 lose the anticoagulant activity and remarkably preserve the antiproliferative one. CONCLUSIONS: All ODNs have shown antiproliferative activities against two cancer cell lines but only those with U and B are endowed with anticoagulant activities similar or improved compared to TBA. GENERAL SIGNIFICANCE: The appropriate site-specific replacement of the residues in the TT loops of TBA with commercially available thymine analogues is a useful strategy either to improve the anticoagulant activity or to preserve the antiproliferative properties by quenching the anticoagulant ones.

AB - A new series of oxopyrrolidines was synthesized and evaluated for their effect on Alzheimer's disease by measuring their inhibitory activity against acetyl cholinesterase enzyme and amyloid beta 42 protein. Most of the compounds showed good inhibitory activity with ethyl 2-(2-(2, 6-dimethylphenylcarbamoyl)- 5 oxopyrrolidin-1-yl) acetate (V) having the highest activity against acetyl cholinesterase with IC50 value 1.84 ng/g tissue compared to standard donepezil 3.34 ng/g tissue. Furthermore, compound 1-((4-(4-chlorophenyl) piperazin-1-yl) methyl)-N-(2,6-dimethylphenyl)-5- oxopyrrolidine- 2-carboxamide (IIIe) displayed the highest activity against beta 42 protein with IC50 value of 11.3 Pg/g tissue compared to 18.4 Pg/g tissue of donepezil.

AB - Curcumin is a multi-functional pharmacologically safe natural agent with proven cytoprotective effects to healthy human cells. In this study, a new series of sulfonamides with curcumin scaffold were synthesized, characterized and investigated for their carbonic anhydrase isoenzyme I (human) and II (bovine) isoforms. The structures of newly synthesized compounds were described by IR, 1H NMR and 13C NMR spectral data. Compound 14 showed the Ki value of 0.99 uM with highest inhibitory activity among all other synthesized compounds against hCA-I enzyme. Similarly enzyme kinetic studies of compound 14, 16 and 30 against bCAII enzyme showed Ki values of 0.71, 0.67 and 0.71 uM respectively. Our biological assays results showed that most of active compounds have similar inhibitory activities compared to standard acetazolamide drug. The molecular docking predicted binding modes showed that these compounds bind with hCA-1 enzyme in similar fashion. PMID- 29190480 TI - Treatment of a highly-concentrated sulphate-rich synthetic wastewater using calcium hydroxide in a fluidised bed crystallizer. AB - This study aimed to investigate factors that affect the conversion of sulphates and magnesium, and the recovery of gypsum and magnesium hydroxide in the neutralization of a sulphate rich stream using calcium hydroxide, in a laboratory scale seeded fluidised bed crystallizer. Particular focus was on reducing the precipitated fines that escaped with the treated water, through the use of seeds, while removing as much sulphate-compounds from the waste stream as possible. The composition of the total sulphate salts was as follows: 80% magnesium sulphate, calcium sulphate remaining at its saturation concentration (1.5 g/L), with the remainder being sodium sulphate based on typical reverse osmosis retentate concentrations ranging from 1.5 - 120 g/L of total sulphate salts. The fluidised bed crystallizer, using silica seeds, was found to be effective at reducing the formation of gypsum and magnesium hydroxide fines by almost half. Feed concentrations of 35 g/L of total salts yielded better sulphate conversions (+/ 75%), compared to a feed concentration of 8 g/L (+/-30%). It was possible to remove 99% of the magnesium in the saline wastewater stream using a calcium to sulphate ratio of 1:1 for feed concentrations of 15 g/L and higher. Excess calcium hydroxide suspension improved sulphate conversions. PMID- 29190481 TI - A novel Fe-La-Ce tri-metallic composite for the removal of fluoride ions from aqueous media.

AB - Pharmaceuticals are environmental micropollutants that pose an emerging challenge because they are poorly eliminated in conventional wastewater treatment plants. Over the last decade, many attempts have been made to solve this problem, and wastewater fungal treatment is a promising alternative. In this study, six different ligninolytic fungi (Trametes versicolor, Ganoderma lucidum, Irpex lacteus, Stropharia rugosoannulata, Gymnopilus luteofolius and Agrocybe erebia) were studied as bioremediation candidates for the removal and degradation of six recalcitrant pharmaceutical micropollutants: Carbamazepine (CBZ), Venlafaxine (VFX), Iopromide (IPD), Diclofenac (DCF), Cyclophosphamide (CFD) and Ifosfamide (IFD). Self-immobilization in a pellet shape was achieved for all fungal mycelia (which was the first time that this was reported for S. rugosoannulata, G. luteofolius, and A. erebia). Biodegradation achievement was greater than 90% for IPD with G. luteofolius and greater than 70% for CBZ with S. rugosoannulata, which suggests a great potential for this alternative biological treatment. Besides, this was the first report where fungal treatment achieved CFD and IFD removals greater than 20% for the treatment with T. versicolor, G. lucidum and S. rugosoannulata. PMID- 29190483 TI - Eggshell membrane as a novel bio sorbent for remediation of boron from desalinated water. AB - This study investigated the use of eggshell membrane (ESM) as a bio-sorbent and the effect of temperature, pH, and initial concentration on its efficiency. Furthermore, by altering the chemical composition, modified eggshell membrane (MESM) was prepared, and its efficiency was compared with the ESM. Results showed that the adsorption of boron preferred an acidic condition; pH 6 at 35 degrees C. In addition, the positive value of DeltaH degrees suggested that the reaction favored endothermic pathway, while the negative value for DeltaG degrees further suggested that the adsorption process was spontaneous. Furthermore, the ESM could adsorb 97% of boron, while MESM was able to adsorb 95%. From the Fourier transform infrared (FTIR), different functional groups were recorded on the surface of the ESM and MESM, and they played key role in the boron adsorption mechanisms. Linear Freundlich model was suggested to best describe the experimental data with 99.4% correlation coefficient. PMID- 29190484 TI - A new biostimulation approach based on the concept of remaining P for soil bioremediation. AB - C:N:P ratio is generally adopted to estimate the amount of nitrogen and phosphorus to be added to soils to accelerate biodegradation of organic contaminants. However, differences in P fixation among soils lead to varying amounts of available P when a specific dose of the element is applied to different soils. Thus, the application of fertilizers to achieve a previously established C:P ratio leads to biodegradation rates that can be lower than the theoretical maximum. In this study, we developed an equation to estimate the dose of P required to maximize organic contaminant biodegradation in soils as a function of remaining P (P-rem), using diesel as a model contaminant. The soils were contaminated with diesel and received six doses of P. CO2 emission was used to estimate biodegradation of hydrocarbons. Biodegradation increased with P doses. The P level that provided the highest hydrocarbon biodegradation rate showed linear and negative correlation with P-rem. The result shows that the requirement for P decreases as the P-rem of the soil increases (or the P-fixing capacity decreases). The dose of P recommended to maximize hydrocarbon biodegradation rate in soil can be estimated by the formula P (mg/dm3) = 436.5 5.39 * P-rem (mg/L).

AB - As a new class of organic optical nanomaterials, semiconducting polymer nanoparticles (SPNs) have the advantages of excellent optical properties, high photostability, facile surface functionalization, and are considered to possess good biocompatibility for biomedical applications. This review surveys recent progress made on the design and synthesis of SPNs for molecular imaging and cancer phototherapy. A variety of novel polymer design, chemical modification and nanoengineering strategies have been developed to precisely tune up optoelectronic properties of SPNs to enable fluorescence, chemiluminescence and photoacoustic (PA) imaging in living animals. With these imaging modalities, SPNs have been demonstrated not only to image tissues such as lymph nodes, vascular structure and tumors, but also to detect disease biomarkers such as reactive oxygen species (ROS) and protein sulfenic acid as well as physiological indexes such as pH and blood glucose concentration. The potentials of SPNs in cancer phototherapy including photodynamic and photothermal therapy are also highlighted with recent examples. Future efforts should further expand the use of SPNs in biomedical research and may even move them beyond pre-clinical studies.

AB - In this research, a stable graphene oxide (GO) suspension was prepared by chemical reduction method from graphite powder. By TEM, the irregular GO sheets with single-atom-layered structure could be observed. The zeta potentials measurement indicated the surface charges of GO were strongly related to pH. BET analysis showed the GO had a specific surface area of 30.7 m2/g and pore volume of 0.10 cm3/g. When the GO was used to remove the residual cellulase in bio polishing effluent, it was found the removal capacity reached its maximum value at the pH 4-5. The kinetics studies showed that the removal process of cellulase followed a pseudo-second-order kinetic model with a rate constant (k2) of 0.276 * 10-3 g/mg min and equilibrium adsorption capacity of 278.55 mg/g, respectively. By plotting the adsorption isotherms, it was found the Langmuir model fitted the experimental data well with a cellulase adsorption capacity of 574.71 mg/g, indicating the adsorption of cellulase by GO in a monolayer manner. When dyeing the cotton fabrics with reactive dyes, it was found that the cotton fabrics could acquire similar color properties in the recycled bio-polishing effluent as in fresh water, meaning the effectiveness of removing cellulase by GO and the feasibility of recycling the bio-polishing effluent.

AB - Ossicular fixation through otosclerosis, chronic otitis media and other pathologies, especially tympanosclerosis, are treated by surgery if hearing aids fail as an alternative. However, the best hearing outcome is often based on knowledge of the degree and location of the fixation. Objective methods to quantify the degree and position of the fixation are largely lacking. Laser vibrometry is a known method to detect ossicular fixation but clinical applicability remains limited. A new method, minimally invasive laser vibrometry (MIVIB), is presented to quantify ossicle mobility using laser vibrometry measurement through the ear canal after elevating the tympanic membrane, thus making the method feasible in minimally invasive explorative surgery. A floating mass transducer provides a clinically relevant transducer to drive ossicular vibration. This device was attached to the manubrium and drove vibrations at the same angle as the longitudinal axis of the stapes and was therefore used to assess ossicular chain mobility in a fresh-frozen temporal bone model with and without stapes fixation. The ratio between the umbo and incus long process was shown to be useful in assessing stapes fixation. The incus-to-umbo velocity ratio decreased by 15 dB when comparing the unfixated situation to stapes fixation up to 2.5 kHz. Such quantification of ossicular fixation using the incus-to-umbo velocity ratio would allow quick and objective analysis of ossicular chain fixations which will assist the surgeon in surgical planning and optimize hearing outcomes.

AB - Unilateral hearing loss (UHL) occurs in 25% of cases of congenital sensorineural hearing loss. Due to the unilaterally reduced audibility associated with UHL, everyday demanding listening situations may be disrupted despite normal hearing in one ear. The aim of this study was to quantify acute changes in recognition of speech in spatially separate competing speech and sound localization accuracy, and relate those changes to two levels of temporary induced UHL (UHL30 and UHL43; suffixes denote the average hearing threshold across 0.5, 1, 2, and 4 kHz) for 8 normal-hearing adults. A within-subject repeated-measures design was used (normal binaural conditions, UHL30 and UHL43). The main outcome measures were the threshold for 40% correct speech recognition and the overall variance in sound localization accuracy quantified by an Error Index (0 = perfect performance, 1.0 = random performance). Distinct and statistically significant deterioration in speech recognition (2.0 dB increase in threshold, p < 0.01) and sound localization (Error Index increase of 0.16, p < 0.001) occurred in the UHL30 condition. Speech recognition did not significantly deteriorate further in the UHL43 condition (1.0 dB increase in speech recognition threshold, p > 0.05), while sound localization was additionally impaired (Error Index increase of 0.33, p < 0.01) with an associated large increase in individual variability. Qualitative analyses on a subject-by-subject basis showed that high-frequency audibility was important for speech recognition, while low-frequency audibility was important for horizontal sound localization accuracy. While the data might not be entirely applicable to individuals with long-standing UHL, the results suggest a need for intervention for mild-to-moderate UHL. PMID- 29190489 TI - Critical role of top-down processes and the push-pull mechanism in semantic single negative priming. AB - The present study investigated the roles of bottom-up mask-triggered inhibition and top-down inhibition in semantic categorization using the single negative priming (NP) paradigm. The masking (bottom-up) and ignore instructions (top-down, i.e., instructing participants to ignore the primes) were manipulated in Experiments 1-3 and Experiment 4, respectively. No priming was observed when only the masking was manipulated (Experiments 2 and 3), but NP was observed when a possible top-down ignore strategy (Experiment 1) or an ignore instruction (Experiment 4) was added. The results indicate that bottom-up mask-triggered inhibition cannot elicit semantic single NP by itself. However, top-down inhibition from an ignore instruction or ignore strategy is critical for triggering reliable semantic single NP. The findings suggest that semantic single NP originates from a push-pull mechanism by facilitating responses to unrelated trials and inhibiting responses to related trials. The experimental evidence also suggests that unconscious processes can be modulated by top-down control. PMID- 29190490 TI - Legionella quorum sensing and its role in pathogen-host interactions. AB - Legionella pneumophila is a water-borne opportunistic pathogen causing a life threatening pneumonia called 'Legionnaires' disease'. The Legionella quorum sensing (Lqs) system produces and responds to the alpha-hydroxyketone signaling molecule 3-hydroxypentadecane-4-one (Legionella autoinducer-1, LAI-1). The Lqs system controls the switch between the replicative/non-virulent and the transmissive/virulent phase of L. pneumophila, and it is a major regulator of natural competence, motility and virulence of the pathogen. Yet, beyond gene regulation, LAI-1 also directly affects pathogen-host interactions, since the signaling molecule modulates the migration of eukaryotic cells. Genes encoding Lqs homologues are present in many environmental bacteria, suggesting that alpha hydroxyketone signaling is widely used for inter-bacterial as well as inter kingdom signaling. In this review we summarize recent advances on the characterization of the Lqs system and its role in L. pneumophila-host cell interactions. PMID- 29190491 TI - Lipid metabolism and its implication in mycobacteria-host interaction. AB - The complex lipids present in the cell wall of Mycobacterium tuberculosis (Mtb) act as major effector molecules that actively interact with the host, modulating its metabolism and stimulating the immune response, which in turn affects the physiology of both, the host cell and the bacilli. Lipids from the host are also nutrient sources for the pathogen and define the fate of the infection by modulating lipid homeostasis. Although new technologies and experimental models of infection have greatly helped understanding the different aspects of the host pathogen interactions at the lipid level, the impact of this interaction in the Mtb lipid regulation is still incipient, mainly because of the low background knowledge in this area of research. PMID- 29190492 TI - Determinants for Effective ALECSAT Immunotherapy Treatment on Autologous Patient Derived Glioblastoma Stem Cells. AB - Glioblastoma (GBM) is the most aggressive primary brain tumor with a median survival of less than 15 months, emphasizing the need for better treatments. Immunotherapy as a treatment for improving or aiding the patient's own immune defense to target the tumor has been suggested for GBM. A randomized clinical trial of adoptive cell transfer using ALECSAT (Autologous Lymphoid Effector Cells Specific Against Tumor Cells) is currently ongoing in Sweden. Here we performed a paired pre-clinical study to investigate the composition and in vitro effect of ALECSAT and identify determinants for the effect using autologous GBM-derived cancer stem cells (CSC), immunocytochemistry and flow cytometry. We show a clear dose-response relationship of ALECSAT on CSC, suggesting that the number of infused cells is of importance. In addition, the in vitro effect of ALECSAT on CSC correlated significantly to the blood count of T helper (Th) cells in the patient indicating a potential benefit of collecting cells for ALECSAT preparation at an even earlier stage when patients generally have a better blood count. The factors identified in this study will be important to consider in the design of future immunotherapy trials to achieve prolonged survival. PMID- 29190495 TI - Global Uniform Asymptotic Fixed Deviation Stability and Stability for Delayed Fractional-order Memristive Neural Networks with Generic Memductance. AB - In this paper, we study global uniform asymptotic fixed deviation stability and stability for a wide class of memristive neural networks with time-varying delays. Firstly, a new mathematical expression of the generic memductance (memristance) is proposed according to the feature of the memristor and the general current-voltage characteristic and a new class of neural networks is designed. Next, a new concept of stability (fixed deviation stability) is proposed in order to describe veritably the stability characteristics of the discontinuous system and the sufficient conditions are given to guarantee the global uniform asymptotic fixed deviation stability and stability of the new system. Finally, two numerical examples are provided to show the applicability and effectiveness of our main results. PMID- 29190493 TI - BIGH3 Promotes Osteolytic Lesions in Renal Cell Carcinoma Bone Metastasis by Inhibiting Osteoblast Differentiation. AB - BACKGROUND: Bone metastasis is common in renal cell carcinoma (RCC), and the lesions are mainly osteolytic. The mechanism of bone destruction in RCC bone metastasis is unknown. METHODS: We used a direct intrafemur injection of mice with bone-derived 786-O RCC cells (Bo-786) as an in vivo model to study if inhibition of osteoblast differentiation is involved in osteolytic bone lesions in RCC bone metastasis. RESULTS: We showed that bone-derived Bo-786 cells induced osteolytic bone lesions in the femur of mice. We examined the effect of conditioned medium of Bo-786 cells (Bo-786 CM) on both primary mouse osteoblasts and MC3T3-E1 preosteoblasts and found that Bo-786 CM inhibited osteoblast differentiation. Secretome analysis of Bo-786 CM revealed that BIGH3 (Beta ig h3 protein), also known as TGFBI (transforming growth factor beta-induced protein), is highly expressed. We generated recombinant BIGH3 and found that BIGH3 inhibited osteoblast differentiation in vitro. In addition, CM from Bo-786 BIGH3 knockdown cells (786-BIGH3 KD) reduced the inhibition of osteoblast differentiation compared to CM from vector control. Intrafemural injection of mice with 786-BIGH3 KD cells showed a reduction in osteolytic bone lesions compared to vector control. Immunohistochemical staining of 18 bone metastasis specimens from human RCC showed strong BIGH3 expression in 11/18 (61%) and moderate BIGH3 expression in 7/18 (39%) of the specimens. CONCLUSIONS: These results suggest that suppression of osteoblast differentiation by BIGH3 is one of the mechanisms that enhance osteolytic lesions in RCC bone metastasis, and raise the possibilty that treatments that increase bone formation may improve therapy outcomes. PMID- 29190494 TI - FUS-CHOP Promotes Invasion in Myxoid Liposarcoma through a SRC/FAK/RHO/ROCK Dependent Pathway. AB - Deregulated SRC/FAK signaling leads to enhanced migration and invasion in many types of tumors. In myxoid and round cell liposarcoma (MRCLS), an adipocytic tumor characterized by the expression of the fusion oncogene FUS-CHOP, SRC have been found as one of the most activated kinases. Here we used a cell-of-origin model of MRCLS and an MRCLS cell line to thoroughly characterize the mechanisms of cell invasion induced by FUS-CHOP using in vitro (3D spheroid invasion assays) and in vivo (chicken chorioallantoic membrane model) approaches. FUS-CHOP expression activated SRC-FAK signaling and increased the invasive ability of MRCLS cells. In addition, FAK expression was found to significantly correlate with tumor aggressiveness in sarcoma patient samples. The involvement of SRC/FAK activation in FUS-CHOP-mediated invasion was further confirmed using the SRC inhibitor dasatinib, the specific FAK inhibitor PF-573228, and FAK siRNA. Notably, dasatinib and PF573228 could also efficiently block the invasion of cancer stem cell subpopulations. Downstream of SRC/FAK signaling, we found that FUS-CHOP expression increases the levels of the RHO/ROCK downstream effector phospho-MLC2 (T18/S19) and that this activation was prevented by dasatinib or PF573228. Moreover, the ROCK inhibitor RKI-1447 was able to completely abolish invasion in FUS-CHOP-expressing cells. These data uncover the involvement of SRC/FAK/RHO/ROCK signaling axis in FUS-CHOP-mediated invasion, thus providing a rationale for testing inhibitors of this pathway as potential novel antimetastatic agents for MRCLS treatment. PMID- 29190496 TI - Rerouting mesenchymal stem cell trajectory towards epithelial lineage by engineering cellular niche. AB - Mesenchymal stromal/stem cells (MSCs) are multipotent cells that offer a promising outcome in the field of regenerative medicine. MSCs are present in various tissues including bone marrow, fat, skin, and placenta. The interest in clinical application of these mesoderm-derived MSCs is primarily fueled by their high self-renewal capacity and multipotency. Although, early studies indicated limited differentiation capacity of MSCs into same cell lineages from which they were isolated, subsequent investigations showed differentiation potential into other cell types of mesoderm origin including osteoblasts, adipocytes, fibroblasts, cardiomyocytes, and chondrocytes. Furthermore, MSCs exhibit a remarkable feature of transdifferentiation into ectodermal, neuroectodermal, and endodermal cells, phenomena referred to as 'stem cell plasticity'. This opened the possibility of clinical applications of MSCs in the regeneration of other tissues like corneal reconstruction, treatment of acute lung injury, oral mucosal regeneration, homing of MSCs for regeneration at sites of injury etc. Though several evidence have accrued demonstrating this phenomenon, there is still a gap in understanding the molecular mechanism of such transitions which will be important to efficiently control the process. Interestingly, the process can be drawn a parallel with the Mesenchymal to Epithelial Transitions (MET) that takes place inside the body during embryonic development or certain pathophysiological conditions. In this review, a brief attempt is first made to understand the evidence of MSC transdifferentiation based on the current knowledge about MET. We then specifically focus on systematic presentation and analysis of the microenvironment factors involved in MSC transdifferentiation to epithelial lineages which would have applications in regenerative medicine. PMID- 29190497 TI - Red blood cell-like particles with the ability to avoid lung and spleen accumulation for the treatment of liver fibrosis. AB - Micro-sized drug-carrier particles accumulate mainly in the lungs and nano-sized particles tend to accumulate in the liver and spleen. Here, we show that micro particles designed to mimic red blood cells (RBCs) can overcome these limitations. The RBC-MPs created in this study have a unique intra-particle elasticity distribution (IED), enabling them to bend around the central axis of the RBC-like dent, enabling them to pass through pores smaller than their diameter, mechanically behaving as authentic RBCs. In contrast, spherical MPs (SPH-MPs) and RBC-MPs hardened by incorporating a siloxane network (SiO2-RBC MPs), could not. In addition to the IED, we discovered that the deformability also depends on the shape and average particle elasticity. RBC-MPs did not accumulate in the lungs and the spleen, but were targeted specifically to the liver instead. In contrast, non-RBC-MPs such as SPH-MPs and SiO2-RBC-MPs showed heavy accumulation in the lungs and/or spleen, and were dispersed non specifically in various organs. Thus, controlling the shape and mechanical properties of RBC-MPs is important for achieving the desired biodistribution. When RBC-MPs were loaded with a (TGF)-beta receptor inhibitor, RBC-MPs could treat liver fibrosis without pneumotoxicity. PMID- 29190498 TI - A gapmer aptamer nanobiosensor for real-time monitoring of transcription and translation in single cells. AB - Transcription and translation are under tight spatiotemporal regulation among cells to coordinate multicellular organization. Methods that allow massively parallel detection of gene expression dynamics at the single cell level are required for elucidating the complex regulatory mechanisms. Here we present a multiplex nanobiosensor for real-time monitoring of protein and mRNA expression dynamics in live cells based on gapmer aptamers and complementary locked nucleic acid probes. Using the multiplex nanobiosensor, we quantified spatiotemporal dynamics of vascular endothelial growth factor A mRNA and protein expressions in single human endothelial cells during microvascular self-organization. Our results revealed distinct gene regulatory processes in the heterogeneous cell subpopulations. PMID- 29190499 TI - Crosstalk between developing vasculature and optogenetically engineered skeletal muscle improves muscle contraction and angiogenesis. AB - Capillary networks surrounding skeletal muscle play an important role in not only supplying oxygen and nutrients but also in regulating the myogenesis and repair of skeletal muscle tissues. Herein, we model the early stages of 3D vascularized muscle fiber formation in vitro using a sequential molding technique to investigate interactions between angiogenesis of endothelial cells and myogenesis of skeletal muscle cells. Channelrhodopsin-2 C2C12 muscle fiber bundles and 3D vascular structures (600 MUm diameter) were formed at 500 MUm intervals in a collagen gel. Endothelial cells exhibited an emergent angiogenic sprouting behavior over several days, which was modulated by the muscle fiber bundle through the secretion of angiopoietin-1. Through a reciprocal response, myogenesis was also upregulated by interactions with the vascular cells, improving muscle contraction via angiopoetin-1/neuregulin-1 signaling. Moreover, continuous training of muscle tissue by optical stimulation induced significantly more angiogenic sprouting. This in vitro model could be used to better understand the formation of vascularized muscle tissues and to test the interactions between muscle growth, repair or training and angiogenesis for applications in tissue engineering and regenerative medicine. PMID- 29190500 TI - Inhibition of intrinsic coagulation improves safety and tumor-targeted drug delivery of cationic solid lipid nanoparticles. AB - Cationic solid lipid nanoparticles (cSLNs) are promising nanoparticles for controlled drug delivery. Increasing surface charge and/or reducing PEG density enhance cellular uptake of cSLNs in vitro, but for unknown reasons fail to improve drug delivery in vivo. Herein, we show that cSLNs present a risk for systemic platelet activation and aggregation in vivo, and this toxic effect can be significantly augmented by increasing the surface charge and reducing the PEG density. Furthermore, thrombotic toxicity significantly reduces blood circulation time and in vivo cellular uptake of cSLNs. Mechanistic studies revealed that the intrinsic coagulation pathway is responsible for cSLN-induced platelet activation. Importantly, pretreatment of the recipient mice with heparin, a clinically-approved intrinsic coagulation inhibitor, was highly effective in preventing toxicity, prolonging the circulation time of cSLNs, and improving cSLN based antitumor drug delivery and therapeutic efficacy in tumor-bearing mice. This study offers a useful strategy for improving both the safety and efficacy of cSLN-based anticancer therapies. PMID- 29190501 TI - Biomaterials-based 3D cell printing for next-generation therapeutics and diagnostics. AB - Building human tissues via 3D cell printing technology has received particular attention due to its process flexibility and versatility. This technology enables the recapitulation of unique features of human tissues and the all-in-one manufacturing process through the design of smart and advanced biomaterials and proper polymerization techniques. For the optimal engineering of tissues, a higher-order assembly of physiological components, including cells, biomaterials, and biomolecules, should meet the critical requirements for tissue morphogenesis and vascularization. The convergence of 3D cell printing with a microfluidic approach has led to a significant leap in the vascularization of engineering tissues. In addition, recent cutting-edge technology in stem cells and genetic engineering can potentially be adapted to the 3D tissue fabrication technique, and it has great potential to shift the paradigm of disease modeling and the study of unknown disease mechanisms required for precision medicine. This review gives an overview of recent developments in 3D cell printing and bioinks and provides technical requirements for engineering human tissues. Finally, we propose suggestions on the development of next-generation therapeutics and diagnostics. PMID- 29190502 TI - NaCl - Changes stem morphology, anatomy and phloem structure in Lucerne (Medicago sativa cv. Gabes): Comparison of upper and lower internodes. AB - In M. sativa cv. Gabes plants treated with 150mM NaCl, the height of the stem is decreased and the internode number, length and diameter are reduced. This depressive effect on growth, but also on photosynthetic activity and water balance, is accompanied by structural changes. In the upper internodes, NaCl treatment increases cambium development, so that the vascular ring is initiated earlier than in controls. In the lower internodes, the number of lignified phloem fibers is increased by NaCl, and their wall thickness is augmented, compared to controls; in the phloem complex, the nacreous layer is enlarged, the number of internal wall ingrowths is increased, but companion cells are damaged. In the treated lower internodes, few vessels occur in the secondary xylem, which is by contrast rich in lignified fibers and in wide vessels grouped in the metaxylem area; protoxylem parenchyma and adjacent pith are also lignified. In addition, in treated lower internodes, starch grains are less abundant than in controls, and this variation might be related to the decrease of photosynthesis. When taken together, qualitative and quantitative results indicate that the saline stress has a marked morpho-anatomical impact on the M. sativa Gabes stem. In particular, variations of secondary derivative distribution, increased wall thickening, lignification of phloem and xylem fibers and damage in the phloem complex are NaCl-induced responses, and are more expressed in the lower than in the upper internodes. The reinforcement of the stem lignified vasculature is thus a positive response to stress, but it has a negative impact on the quality of the forage. PMID- 29190503 TI - The interaction between human blood neutrophil granulocytes and quantum dots. AB - For biomedical applications, it is important to know, which kinds of blood cells can capture quantum dots (QDs). The maximum accumulation of QDs was found for the monocyte fraction of leukocytes, the minimum binding of QDs was observed for lymphocytes. It was found that CdSe/ZnS-MPA QDs are actively absorbed by the cells and have more expressed toxicity. The classical mechanism of the phagocytosis of QDs was revealed for neutrophils, when the QDs are located in phagolysosomes. The capture of QDs by neutrophil granulocytes has resulted in a destruction of certain types of QDs. The interaction of the neutrophils with the QDs has resulted in the death of the cells by one of the following cell death mechanisms: necrosis, apoptosis, autophagy, NETos, or mummification. The aggregation of the QDs manifested as an increase of the hydrodynamic diameter of the QDs was found to occur under the influence of serum and under the influence of blood cells (lymphocytes and neutrophils) in a serum-free medium. PMID- 29190504 TI - Phytohormone priming elevates the accumulation of defense-related gene transcripts and enhances bacterial blight disease resistance in cassava. AB - Cassava bacterial blight (CBB) disease caused by Xanthomonas axonopodis pv. manihotis (Xam) is a severe disease in cassava worldwide. In addition to causing significant cassava yield loss, CBB disease has not been extensively studied, especially in terms of CBB resistance genes. The present research demonstrated the molecular mechanisms underlining the defense response during Xam infection in two cassava cultivars exhibiting different degrees of disease resistance, Huay Bong60 (HB60) and Hanatee (HN). Based on gene expression analysis, ten of twelve putative defense-related genes including, leucine-rich repeat receptor-like kinases (LRR-RLKs), resistance (R), WRKY and pathogenesis-related (PR) genes, were differentially expressed between these two cassava cultivars during Xam infection. The up-regulation of defense-related genes observed in HB60 may be the mechanism required for the reduction of disease severity in the resistant cultivar. Interestingly, priming with salicylic acid (SA) or methyl jasmonate (MeJA) for 24 h before Xam inoculation could enhance the defense response in both cassava cultivars. The disease severity was decreased 10% in the resistant cultivar (HB60) and was remarkably reduced 21% in the susceptible cultivar (HN) by SA/MeJA priming. Priming with Xam inoculation modulated cassava4.1_013417, cassava4.1_030866 and cassava4.1_020555 (highest similarity to MeWRKY59, MePR1 and AtPDF2.2, respectively) expression and led to enhanced resistance of the susceptible cultivar in the second infection. The putative cis-regulatory elements were predicted in an upstream region of these three defense-related genes. The different gene expression levels in these genes between the two cultivars were due to the differences in cis-regulatory elements in their promoter regions. Taken together, our study strongly suggested that the induction of defense-related genes correlated with defense resistance against Xam infection, and exogenous application of SA or MeJA could elevate the defense response in both cultivars of cassava. This finding should pave the way for management to reduce yield loss from disease and genetic improvement in cassava. PMID- 29190511 TI - Follow (or don't follow) the crowd: Young children's conformity is influenced by norm domain and age. AB - This study investigated whether young children's conformity to a consensus varies across the normative domain and age. A total of 168 3- and 5-year-olds participated. Each child was presented with a puzzle box that had two transparent compartments. In a reward preference condition, one of the compartments contained 1 sticker, whereas the other compartment contained 12 stickers. In perceptual judgment and arbitrary preference conditions, one compartment contained a short plank, whereas one contained a perceptually longer plank. Each child was shown a video of four female adults, each of whom was asked the same question within condition: "Which one's the biggest?" (perceptual task; each model retrieved the smaller block), "Which one do you want?" (reward preference; each model retrieved the smaller reward), and "Which one do you want?" (arbitrary preference; each model retrieved the smaller plank). Children were then asked the same question by condition and were allowed to retrieve the item. Notably, more children conformed in the arbitrary preference condition than in the reward preference and perceptual judgment conditions, with 3-year-olds conforming significantly more than 5-year-olds. The 5-year-olds were more successful and imitated with greater fidelity, including demonstrating overimitation. However, less overimitation was observed in the arbitrary preference condition. Together, these findings show that children are sensitive to the contextual cues of the domain in which they are witnessing norms and vary their own conformity based on such cues. Furthermore, children can navigate which information to copy to fulfil their own ends. PMID- 29190516 TI - 57Fe internal field nuclear magnetic resonance and Mossbauer spectroscopy study of Li-Zn ferrites. AB - We report the internal field nuclear magnetic resonance (IFNMR) and Mossbauer spectroscopy study of Li-Zn ferrites at RT. The results were supported by the IFNMR data measured at 77 K. As Zn concentration increases the IFNMR echo amplitude decreases and below certain Zn concentration no signal was detected. At RT the echo amplitude vanishes at a lower Zn concentration, whereas at 77 K, the echo amplitude does not vanish completely (except for pure Zn-ferrite). However, in Mossbauer spectroscopy at RT, we have observed magnetically ordered state of all the Li-Zn ferrite samples. This discrepancy could be related to the difference between the time scale of detection of the spins by Mossbauer spectroscopy (10-7-10-10 s) and NMR spectroscopy (10-6 s). Hence, sensitivity of zero-field NMR depends on the magnetic hyperfine field, temperature and abundance of the magnetic cations at the lattice of the spinel ferrites. We have demonstrated that the 'two-equal-pulses' sequence leads to higher echo signal than the spin echo pulse sequence due to the presence of distribution of internal magnetic fields throughout the material. We obtained a limiting value for the fraction of spins needed to produce an echo signal at a particular temperature and at a particular site of the Li-Zn ferrite spinels that can be sensitively detected by pulsed IFNMR technique. PMID- 29190505 TI - Advances in sarcoma gene mutations and therapeutic targets. AB - Sarcomas are rare and complex malignancies that have been associated with a poor prognostic outcome. Over the last few decades, traditional treatment with surgery and/or chemotherapy has not significantly improved outcomes for most types of sarcomas. In recent years, there have been significant advances in the understanding of specific gene mutations that are important in driving the pathogenesis and progression of sarcomas. Identification of these new gene mutations, using next-generation sequencing and advanced molecular techniques, has revealed a range of potential therapeutic targets. This, in turn, may lead to the development of novel agents targeted to different sarcoma subtypes. In this review, we highlight the advances made in identifying sarcoma gene mutations, including those of p53, RB, PI3K and IDH genes, as well as novel therapeutic strategies aimed at utilizing these mutant genes. In addition, we discuss a number of preclinical studies and ongoing early clinical trials in sarcoma targeting therapies, as well as gene editing technology, which may provide a better choice for sarcoma patient management. PMID- 29190508 TI - Evaluation of sediment and 137Cs redistribution in the Oginosawa River catchment near the Fukushima Dai-ichi Nuclear Power Plant using integrated watershed modeling. AB - The Oginosawa River catchment lies 15 km south-west of the Fukushima Dai-ichi nuclear plant and covers 7.7 km2. Parts of the catchment were decontaminated between fall 2012 and March 2014 in preparation for the return of the evacuated population. The General-purpose Terrestrial Fluid-flow Simulator (GETFLOWS) code was used to study sediment and 137Cs redistribution within the catchment, including the effect of decontamination on redistribution. Fine resolution grid cells were used to model local features of the catchment, such as paddy fields adjacent to the Oginosawa River. The simulation was verified using monitoring data for river water discharge rates (r = 0.92), suspended sediment concentrations, and particulate 137Cs concentrations (r = 0.40). Cesium-137 input to watercourses came predominantly from land adjacent to river channels and forest gullies, e.g. the paddy fields in the Ogi and Kainosaka districts, as the ground in these areas saturates during heavy rain and is easily eroded. A discrepancy between the simulation and monitoring results on the sediment discharge rate following decontamination may be explained by fast erosion occurring after decontamination. Forested areas far from the channels only made a minor contribution to 137Cs input to watercourses, total erosion of between 0.001 and 0.1 mm from May 2011 to December 2015, as ground saturation is infrequent in these areas. The 2.3-6.9% y-1 decrease in the amount of 137Cs in forest topsoil over the study period can be explained by radioactive decay (approximately 2.3% y 1), along with a migration downwards into subsoil and a small amount of export. The amount of 137Cs available for release from land adjacent to rivers is expected to be lower in future than compared to this study period, as the simulations indicate a high depletion of inventory from these areas by the end of 2015. However continued monitoring of 137Cs concentrations in river water over future years is advised, as recultivation of paddy fields by returnees may again lead to fast erosion rates and release of the remaining inventory. PMID- 29190518 TI - Multiple focal nodular hyperplasia: MRI features. AB - PURPOSE: To describe MRI features of multiple Focal Nodular Hyperplasia (FNHs). METHODS: 40 consecutive subjects (37 females, mean age, 38.8years) were included. All studies were independently reviewed. This was an observational study to define the radiological features of multifocal FNH. RESULTS: 130 lesions were evaluated. The majority (88.5%), were peripheral in location. 92.3% lesions were lobulated. Marked enhancement was present in 94.6% lesions. In the portal venous and delayed phase, 46.2% and 47.7% lesions were mildly hyperintense. Central scar was present in 77% lesions. CONCLUSIONS: Distinctive features included predominant subcapsular location and mild hyperintensity in the delayed phase, seen in nearly 50% of FNHs. PMID- 29190515 TI - B1 gradient coherence selection using a tapered stripline. AB - Pulsed-field gradients are common in modern liquid state NMR pulse sequences. They are often used instead of phase cycles for the selection of coherence pathways, thereby decreasing the time required for the NMR experiment. Soft off resonance pulses with a B1 gradient result in a spatial encoding similar to that created by pulsed-field (B0) gradients. In this manuscript we show that pulse sequences with pulsed-field gradients can easily be converted to one which uses off-resonance B1 field gradient (OFFBEAT) pulses. The advantage of B1 gradient pulses for coherence selection is that the chemical shift evolution during the pulses is (partially) suppressed. Therefore no refocusing echos are required to correct for evolution during the gradient pulses. A tapered stripline is shown to be a convenient tool for creating a well-defined gradient in the B1 field strength. B1 gradient coherence selection using a tapered stripline is a simple and cheap alternative to B0 pulsed-field gradients. PMID- 29190510 TI - Predicted activity of UGT2B7, ABCB1, OPRM1, and COMT using full-gene haplotypes and their association with the CYP2D6-inferred metabolizer phenotype. AB - The pharmacogene, CYP2D6, is commonly used to infer metabolizer phenotype of many marketed drugs and endogenous toxins in ante- and post-mortem patients but only represents the efficiency of phase 1 metabolism. Downstream metabolic enzymes encoded by UGT2B7, ABCB1, OPRM1, and COMT also have been implicated in variable individual response to drugs due to their activity at different stages of the tramadol ADME (absorption, distribution, metabolism, and excretion) process. While commonly studied as single genes using targeted genotyping approaches, a more comprehensive tramadol metabolism profile has not been evaluated. 1000 Genomes Project data for UGT2B7, ABCB1, OPRM1, and COMT were used to characterize full-gene haplotypes and their effect on protein function using in-house excel based workbooks, PopART, and TreeView. Population genetic summary statistics and intergenic analyses associated these haplotypes with full-gene CYP2D6-inferred metabolizer phenotype. The findings suggest that UGT2B7, ABCB1, OPRM1, and COMT may contribute to predicted metabolizer phenotype as opposed to relying solely on CYP2D6. PMID- 29190513 TI - The role of algal organic matter in the separation of algae and cyanobacteria using the novel "Posi" - Dissolved air flotation process. AB - Algae and cyanobacteria frequently require separation from liquid media in both water treatment and algae culturing for biotechnology applications. The effectiveness of cell separation using a novel dissolved air flotation process that incorporates positively charged bubbles (PosiDAF) has recently been of interest but has been shown to be dependent on the algae or cyanobacteria species tested. Previously, it was hypothesised that algal organic matter (AOM) could be impacting the separation efficiency. Hence, this study investigates the influence of AOM on cell separation using PosiDAF, in which bubbles are modified using a commercially available cationic polyelectrolyte poly(N, N-diallyl-N,N dimethylammonium chloride) (PDADMAC). The separation of Chlorella vulgaris CS 42/7, Mychonastes homosphaera CS-556/01 and two strains of Microcystis aeruginosa (CS-564/01 and CS-555/1), all of which have similar cell morphology but different AOM character, was investigated. By testing the cell separation in the presence and absence of AOM, it was determined that AOM enhanced cell separation for all the strains but to different extents depending on the quantity and composition of carbohydrates and proteins in the AOM. By extracting AOM from the strain for which optimal separation was observed and adding it to the others, cell separation improved from <55% to >90%. This was attributed to elevated levels of acidic carbohydrates as well as glycoprotein-carbohydrate conjugations, which in turn were related to the nature and quantity of proteins and carbohydrates present in the AOM. Therefore, it was concluded that process optimisation requires an in-depth understanding of the AOM and its components. If culturing algae for biotechnology applications, this indicates that strain selection is not only important with respect to high value product content, but also for cell separation.

AB - Estimates of mesophyll conductance (gm), when calculated from chlorophyll fluorescence, are uncertain, especially when the photosystem II (PSII) operating efficiency is measured from the traditional single saturation pulse methodology. The multiphase flash method has recently been recommended to replace the single saturation pulse method, allowing a more reliable estimation of gm. Also, many researchers still directly use the PSII operating efficiency to derive linear electron transport rate J (that is required to estimate gm), without appropriate calibration using measurements under non-photorespiratory conditions. Here we demonstrate for tomato and rice that (i) using the multiphase flash method did not yield realistic estimates of gm if no calibration was conducted; and (ii) using the single saturation pulse method still gave reasonable estimates of gm when calibration based on the non-photorespiratory measurements was properly conducted. Therefore, conducting calibration based on data under non photorespiratory conditions was indispensable for a reliable estimation of gm, regardless whether the multiphase flash or the single saturation pulse method was used for measuring the PSII operating efficiency. Other issues related to the procedure of using the chlorophyll fluorescence method to estimate gm were discussed.

AB - BACKGROUND: Reflux esophagitis (RE) may mimic symptoms requiring cross-sectional imaging. METHODS: From 565 patients who had CT and esophagogastroduodenoscopy within four days apart, CT scans of 72 patients with RE confirmed by esophagogastroduodenoscopy and 108 matched patients without RE were evaluated for distal esophageal wall characteristics. RESULTS: In RE patients the distal esophageal wall thickness was greater (5.2+/-2.0mm) compared to patients without RE (3.5+/-1.2mm, p<0.0001) with AUC of 0.78 and 56% sensitivity, 88% specificity for a 5.0mm cut-off. CONCLUSIONS: There is a moderate association between distal esophageal wall thickness on CT and RE diagnosed by esophagogastroduodenoscopy as the reference standard. PMID- 29190512 TI - Free nitrous acid pre-treatment of waste activated sludge enhances volatile solids destruction and improves sludge dewaterability in continuous anaerobic digestion. AB - Previous work has demonstrated that pre-treatment of waste activated sludge (WAS) with free nitrous acid (FNA i.e. HNO2) enhances the biodegradability of WAS, identified by a 20-50% increase in specific methane production in biochemical methane potential (BMP) tests. This suggests that FNA pre-treatment would enhance the destruction of volatile solids (VS) in an anaerobic sludge digester, and reduce overall sludge disposal costs, provided that the dewaterability of the digested sludge is not negatively affected. This study experimentally evaluates the impact of FNA pre-treatment on the VS destruction in anaerobic sludge digestion and on the dewaterability of digested sludge, using continuously operated bench-scale anaerobic digesters. Pre-treatment of full-scale WAS for 24 h at an FNA concentration of 1.8 mg NN/L enhanced VS destruction by 17 +/- 1% (from 29.2 +/- 0.9% to 34.2 +/- 1.1%) and increased dewaterability (centrifuge test) from 12.4 +/- 0.4% to 14.1 +/- 0.4%. Supporting the VS destruction data, methane production increased by 16 +/- 1%. Biochemical methane potential tests indicated that the final digestate stability was also improved with a lower potential from FNA treated digestate. Further, a 2.1 +/- 0.2 log improvement in pathogen reduction was also achieved. With inorganic solids representing 15-22% of the full-scale WAS used, FNA pre-treatment resulted in a 16-17% reduction in the volume of dewatered sludge for final disposal. This results in significantly reduced costs as assessed by economic analysis. PMID- 29190507 TI - Results of methotrexate-etoposide-ifosfamide based regimen (M-EI) in osteosarcoma patients included in the French OS2006/sarcome-09 study. AB - BACKGROUND: In most countries, reference chemotherapy for osteosarcoma is MAP regimen (M = high-dose methotrexate, AP = doxorubicin-cisplatinum). In France, the standard preoperative chemotherapy for children/adolescents combines M and etoposide-ifosfamide (EI), based on the OS94-trial. We report the safety and efficacy results of patients <=25 years treated with preoperative M-EI regimen enroled in the French OS2006-study, between 2007 and 2014. METHODS: Treatment comprised preoperative chemotherapy with the 7 M-courses and 2 EI-courses, then surgery and postoperative chemotherapy assigned by risk's groups: standard-risk (good histological response without metastases) received 12 M-courses, 3 EI courses; high-risk (poor histologic response, initial metastases or unresectable primary) received 5 M-courses alternated with 5 AP-courses. 253 patients were randomised to receive (n = 128) or not (n = 125) zoledronate. RESULTS: 409/522 patients enroled in the OS2006 study who received preoperative M-EI were analysed. Median age was 14.3 years (4.7-24.5), with 55 patients aged 18-25 years. Primary tumour location was limb in 383 patients (94%) and 85 (21%) presented metastases. Median chemotherapy duration was 37.4 weeks. 381 (96%) patients underwent surgery, 258 patients (65%) had a good histologic response. 187/324 patients (58%) with localised disease did not receive doxorubicin nor cisplatinum. Toxicity was evaluated in the randomised study: most patients experienced >=1 severe toxicity (grade IV haematological or grade III/IV extra haematological). Median follow-up was 4.8 years, and 168 patients had events. Five-year event-free survival was 56% (95% CI, 51-62%) and overall survival 71% (66-76%). CONCLUSION: M-EI regimen/strategy was feasible for patient aged <=25 years with survival rates are comparable to those obtained with MAP regimen. PMID- 29190506 TI - Mammographic density and breast cancer risk in breast screening assessment cases and women with a family history of breast cancer. AB - BACKGROUND: Mammographic density has been shown to be a strong independent predictor of breast cancer and a causative factor in reducing the sensitivity of mammography. There remain questions as to the use of mammographic density information in the context of screening and risk management, and of the association with cancer in populations known to be at increased risk of breast cancer. AIM: To assess the association of breast density with presence of cancer by measuring mammographic density visually as a percentage, and with two automated volumetric methods, QuantraTM and VolparaDensityTM. METHODS: The TOMosynthesis with digital MammographY (TOMMY) study of digital breast tomosynthesis in the Breast Screening Programme of the National Health Service (NHS) of the United Kingdom (UK) included 6020 breast screening assessment cases (of whom 1158 had breast cancer) and 1040 screened women with a family history of breast cancer (of whom two had breast cancer). We assessed the association of each measure with breast cancer risk in these populations at enhanced risk, using logistic regression adjusted for age and total breast volume as a surrogate for body mass index (BMI). RESULTS: All density measures showed a positive association with presence of cancer and all declined with age. The strongest effect was seen with Volpara absolute density, with a significant 3% (95% CI 1 5%) increase in risk per 10 cm3 of dense tissue. The effect of Volpara volumetric density on risk was stronger for large and grade 3 tumours. CONCLUSIONS: Automated absolute breast density is a predictor of breast cancer risk in populations at enhanced risk due to either positive mammographic findings or family history. In the screening context, density could be a trigger for more intensive imaging. PMID- 29190522 TI - Ultrasound and MRI of nerves for monitoring disease activity and treatment effects in chronic dysimmune neuropathies - Current concepts and future directions. AB - New imaging modalities like high-resolution-ultrasound (HRUS) and MR-Neurography (MRN) are increasingly used for the evaluation of the peripheral nervous system. The increasing knowledge on morphological changes observed in different neuropathies has led to a better understanding of underlying pathophysiological processes. The diagnosis of acquired chronic dysimmune neuropathies (CDN) like chronic inflammatory demyelinating polyneuropathy (CIDP), Lewis-Sumner Syndrome (LSS) or multifocal motor neuropathy (MMN) can be challenging. The current diagnostic criteria and outcome parameters are mainly based on clinical and electrophysiological parameters. Especially in CDN cases with atypical presentation or during early disease stages, the diagnostic accuracy is low and standardized protocols for the evaluation of disease activity and treatment response are lacking. The establishment of combined diagnostic criteria for CDN including imaging modalities could help to improve the diagnostic accuracy, allow a better differentiation of subtypes and facilitate the follow-up of disease course. The appropriate selection of eligible patients and sensitive monitoring of treatment response is mandatory future in treatment trials. In this article, we briefly summarize the clinical presentations and pathophysiological concepts of different CDN like CIDP, LSS and MMN. Furthermore, this review focuses on the diagnostic value of HRUS/MRN and its potential role for the monitoring of disease activity. PMID- 29190517 TI - Comparing residence-based to actual path-based methods for defining adolescents' environmental exposures using granular spatial data. AB - This paper uses data from a population-based case control study of daily activities and assault injury to examine residence-based versus actual path-based approaches to measuring environmental exposures that pose risks for violence among adolescents. Defining environmental exposures based on participant home address resulted in significant misclassification compared to gold standard daily travel path measures. Dividing participant daily travel paths into origin destination segments, we explore a method for defining spatial counterfactuals by comparing actual trip path exposures to shortest potential trip path exposures. Spatial methods explored herein can be utilized in future research to more accurately quantify environmental exposures and associations with health outcomes. PMID- 29190526 TI - The influence of perceptual similarity and individual differences on false memories in aging. AB - Previous false memory research has suggested that older adults' false memories are based on an overreliance on gist processing in the absence of item-specific details. Yet, false memory studies have rarely taken into consideration the precise role of item-item similarity on the cognitive and neural mechanisms underlying perceptual false memories in older adults. In addition, work in our laboratory has suggested that when investigating the neural basis of false memories in older adults, it is equally as critical to take into account interindividual variability in behavior. With both factors in mind, the present study was the first to examine how both controlled, systematic differences in perceptual relatedness between targets and lures and individual differences in true and false recognition contribute to the neural basis of both true and false memories in older adults. Results suggest that between-subject variability in memory performance modulates neural activity in key regions associated with false memories in aging, whereas systematic differences in perceptual similarity did not modulate neural activity associated with false memories. PMID- 29190525 TI - Cognitive reserve modulates attention processes in healthy elderly and amnestic mild cognitive impairment: An event-related potential study. AB - OBJECTIVES: The study aimed to investigate and compare the effect of cognitive reserve (CR) on brain activation in healthy controls (HC) and amnestic mild cognitive impairment (aMCI) patients during 0-back and 1-back tasks measured by event-related potential (ERP). METHODS: The study recorded 85 subjects (39 aMCI patients and 46 their matched controls) with a 64-channel electroencephalogram (EEG). Subjects performed 0- and 1-back tasks. RESULTS: Compared to HC, aMCI patients showed reduced accuracy, delayed mean correct response time (RT) and decreased P300 amplitude at central-parietal and parietal electrodes. A mediation analysis indicated that higher CR reduced neural inefficiency, which might be associated with better task performance in HC. However, no correlation was detected between CR and neural inefficiency in aMCI patients, whereas higher CR was still related to enhanced accuracy and prolonged RT in aMCI patients. CONCLUSIONS: The present study reported that higher CR could contribute to better task performance via down-regulating neural inefficiency in HC. In addition, higher CR might modulate attention processes in aMCI via a way distinct from that in HC, and eventually result in better task performance. SIGNIFICANCE: The study provided evidence for that improving CR might lower cognitive impairment of healthy elderly and aMCI patients. PMID- 29190509 TI - Genetic determinants of freckle occurrence in the Spanish population: Towards ephelides prediction from human DNA samples. AB - Prediction of human pigmentation traits, one of the most differentiable externally visible characteristics among individuals, from biological samples represents a useful tool in the field of forensic DNA phenotyping. In spite of freckling being a relatively common pigmentation characteristic in Europeans, little is known about the genetic basis of this largely genetically determined phenotype in southern European populations. In this work, we explored the predictive capacity of eight freckle and sunlight sensitivity-related genes in 458 individuals (266 non-freckled controls and 192 freckled cases) from Spain. Four loci were associated with freckling (MC1R, IRF4, ASIP and BNC2), and female sex was also found to be a predictive factor for having a freckling phenotype in our population. After identifying the most informative genetic variants responsible for human ephelides occurrence in our sample set, we developed a DNA based freckle prediction model using a multivariate regression approach. Once developed, the capabilities of the prediction model were tested by a repeated 10 fold cross-validation approach. The proportion of correctly predicted individuals using the DNA-based freckle prediction model was 74.13%. The implementation of sex into the DNA-based freckle prediction model slightly improved the overall prediction accuracy by 2.19% (76.32%). Further evaluation of the newly-generated prediction model was performed by assessing the model's performance in a new cohort of 212 Spanish individuals, reaching a classification success rate of 74.61%. Validation of this prediction model may be carried out in larger populations, including samples from different European populations. Further research to validate and improve this newly-generated freckle prediction model will be needed before its forensic application. Together with DNA tests already validated for eye and hair colour prediction, this freckle prediction model may lead to a substantially more detailed physical description of unknown individuals from DNA found at the crime scene. PMID- 29190514 TI - Extracellular vesicles in leukemia. AB - Extracellular vesicles (EV) are nano-sized membrane enclosed vehicles that are involved in cell-to-cell communication and carry cargo that is representative of the parent cell. Recent studies have highlighted the significant roles leukemia EVs play in tumor progression, and ways in which they can lead to treatment evasion, thus meriting further investigation. Leukemia EVs are involved in crosstalk between the leukemia cell and its surroundings, transforming it into a cancer favorable microenvironment. Due to the diverse biological content found in leukemia EVs, they have an assortment of effects on the cells they interact with and can be harnessed as candidates for diagnostic and therapeutic treatments. This review focuses on EVs in the context of leukemia and the means by which they modulate their microenvironment, hematopoiesis, and the immune system to facilitate malignancy. We will also address current and prospective EV-based therapeutics. PMID- 29190521 TI - Presurgical language mapping using event-related high-gamma activity: The Detroit procedure. AB - A number of investigators have reported that event-related augmentation of high gamma activity at 70-110 Hz on electrocorticography (ECoG) can localize functionally-important brain regions in children and adults who undergo epilepsy surgery. The advantages of ECoG-based language mapping over the gold-standard stimulation include: (i) lack of stimulation-induced seizures, (ii) better sensitivity of localization of language areas in young children, and (iii) shorter patient participant time. Despite its potential utility, ECoG-based language mapping is far less commonly practiced than stimulation mapping. Here, we have provided video presentations to explain, point-by-point, our own hardware setting and time-frequency analysis procedures. We also have provided standardized auditory stimuli, in multiple languages, ready to be used for ECoG based language mapping. Finally, we discussed the technical aspects of ECoG-based mapping, including its pitfalls, to facilitate appropriate interpretation of the data. PMID- 29190527 TI - Urinary polycyclic aromatic hydrocarbon metabolites, Club cell secretory protein and lung function. AB - BACKGROUND: Exposure to polycyclic aromatic hydrocarbons (PAHs) has been associated with lung function decline. However, the underlying mechanisms for the association remain unclear. OBJECTIVES: To explore potential role of a lung epithelial biomarker, Club cell secretory protein (CC16), in associations between PAH exposures and lung function decline. METHODS: We investigated 3384 adults from the Wuhan-Zhuhai cohort, and followed up at three years after first examination. Linear mixed models was used to quantify dose-response relationships between urinary monohydroxylated PAH metabolites (OH-PAHs) and lung function, as well as OH-PAHs and plasma CC16. Mediation analysis was conducted to investigate role of CC16 in the association between OH-PAHs and lung function. We also estimated the relationships between OH-PAHs and lung function change in three years among participants with different levels of CC16. RESULTS: Each 1-unit increase of log-transformed total urinary high and low molecular weight OH-PAHs (?HMW OH-PAH and ?LMW OH-PAHs) were associated with a 22.59 and 25.25ml reduction of FEV1 respectively, while?HMW OH-PAH was associated with a 30.38ml reduction of FVC. Moreover, these negative associations between OH-PAHs and lung function levels were significant only among low CC16 group (<15.83ng/ml). CC16 concentration decreased monotonically with increased high molecular weight OH PAHs (?HMW OH-PAHs) when ?HMW OH-PAH concentration was over 0.67MUg/mmol Cr. CC16 mediated 22.13% of the association between ?HMW OH-PAH and FVC among individuals with higher ?HMW OH-PAH. After three years of follow-up, subjects with low level of plasma CC16 had a significant decline of FVC when exposed to high level of ?HMW OH-PAH. CONCLUSIONS: CC16 play an important role in the association between high molecular weight PAHs and FVC. Individuals with low plasma CC16 level might suffer a decline in lung function when exposed to high level of high molecular weight PAHs. PMID- 29190523 TI - Electromagnetic source imaging using simultaneous scalp EEG and intracranial EEG: An emerging tool for interacting with pathological brain networks. AB - OBJECTIVE: The goal of this study is to investigate the performance, merits and limitations of source imaging using intracranial EEG (iEEG) recordings and to compare its accuracy to the results of EEG source imaging. Accuracy in this study, is measured both by determining the location and inter-nodal connectivity of underlying brain networks. METHODS: Systematic computer simulation studies are conducted to evaluate iEEG-based source imaging vs. EEG-based source imaging, and source imaging using both EEG and iEEG. To test the source imaging models, networks of inter-connected nodes (in terms of activity) are simulated. The location of the network nodes is randomly selected within a realistic geometry head model and a connectivity link is created among these nodes based on a multi variate auto-regressive (MVAR) model. Then the forward problem is solved to calculate the potentials at the electrodes and noise (white and correlated) is added to these simulated potentials to simulate realistic measurements. Subsequently, the inverse problem is solved and an algorithm based on principle component analysis is performed on the estimated source activities to determine the location of the simulated network nodes. The activity of these nodes (over time), is then extracted, and used to estimate the connectivity links among the mentioned nodes using Granger causality analysis. RESULTS: Source imaging based on iEEG recordings may or may not improve the accuracy in localization, depending on the number and location of active nodes relative to iEEG electrodes and to other nodes within the network. However, our simulation results suggest that combining EEG and iEEG modalities (simultaneous scalp and intracranial recordings) can improve the imaging accuracy significantly. CONCLUSIONS: While iEEG source imaging is useful in estimating the exact location of sources near the iEEG electrodes, combining EEG and iEEG recordings can achieve a more accurate imaging due to the high spatial coverage of the scalp electrodes and the added near field information provided by the iEEG electrodes. SIGNIFICANCE: The present results suggest the feasibility of localizing brain electrical sources from iEEG recordings and improving EEG source localization using simultaneous EEG and iEEG recordings to cover the whole brain. The hybrid EEG and iEEG source imaging can assist the clinicians when unequivocal decisions about determining the epileptogenic zone cannot be reached using a single modality. PMID- 29190524 TI - Four-dimensional map of the human early visual system. AB - OBJECTIVE: We generated a large-scale, four-dimensional map of neuronal modulations elicited by full-field flash stimulation. METHODS: We analyzed electrocorticography (ECoG) recordings from 63 patients with focal epilepsy, and delineated the spatial-temporal dynamics of visually-elicited high-gamma70-110 Hz amplitudes on a standard brain template. We then clarified the neuronal events underlying visual evoked potential (VEP) components, by correlating with high gamma amplitude measures. RESULTS: The medial-occipital cortex initially revealed rapid neural activation followed by prolonged suppression, reflected by augmentation of high-gamma activity lasting up to 100 ms followed by attenuation lasting up to 1000 ms, respectively. With a number of covariate factors incorporated into a prediction model, the eccentricity representation independently predicted the magnitude of post-activation suppression, which was more intense in regions representing more parafoveal visual fields compared to those of more peripheral fields. The initial negative component on VEP was sharply contoured and co-occurred with early high-gamma augmentation, whose offset then co-occurred with a large positive VEP peak. A delayed negative VEP peak was blunt and co-occurred with prolonged high-gamma attenuation. CONCLUSIONS: Eccentricity-dependent gradient in neural suppression in the medial occipital region may explain the functional difference between peripheral and parafoveal/central vision. Early negative and positive VEP components may reflect neural activation, whereas a delayed negative VEP peak reflecting neural suppression. SIGNIFICANCE: Our observation provides the mechanistic rationale for transient scotoma or mild flash-blindness, characterized by physiological afterimage preferentially formed in central vision following intense but non injurious light exposure. PMID- 29190530 TI - Rare missense coding variants in oxytocin receptor (OXTR) in schizophrenia cases are associated with early trauma exposure, cognition and emotional processing. AB - BACKGROUND: Oxytocin is a peptide hormone that influences the integration of social cognition with behavior and affect regulation. Oxytocin also prominently directs the transition of neuronal GABA neurotransmission from excitatory to inhibitory after birth. The oxytocin receptor (OXTR) is linked to schizophrenia, a heterogeneous syndrome. Relationships of OXTR polymorphisms with specific clinical features could aid in evaluating any role of oxytocin in the pathogenesis of schizophrenia. METHOD: Schizophrenia cases with rare missense coding OXTR single nucleotide variants (SNVs) were identified from a well characterized sample of cases and controls who were assessed for symptoms, cognition and early life trauma. RESULTS: Five of 48 cases showed rare OXTR variants. Compared to the other cases they had less severe negative symptoms (deficits in emotional expression and motivation) and less severe general psychopathology scores (depression and anxiety). They demonstrated lower nonverbal (performance) than verbal intelligence due to deficient perceptual organization and slow processing speed. They also reported greater early trauma exposure (physical and sexual abuse and emotional trauma). CONCLUSION: Cases carrying rare OXTR SNVs had less negative and affective symptoms than other cases, but similar psychotic symptoms, along with specific cognitive deficits. The clinical characterization of these cases occurred in association with environmental exposure to early trauma, especially sexual abuse, which may have influenced the expression of schizophrenia in subjects harboring specific SNVs in the OXTR. PMID- 29190532 TI - Effect of wetting case and softness on adhesion of bioinspired micropatterned surfaces. AB - Inspired by the adhesive ability of amphibian toe-pads, polydimethylsiloxane (PDMS) hexagonal pillar arrayed surfaces with varying softness are fabricated, and their adhesion behaviors in the non-wetting, mostly wetting and totally wetting cases are throughly investigated. Experimental results demonstrate that under a totally wetting case, i.e. the biological toe-pad-like case, besides the long-range capillary force, a short-range interaction caused by close contact plays a significant role for adhesion. Compared with unpatterned surface, hexagonal pillar patterns can lead to a remarkable improvement in both short- and long-range contribution for wet adhesion. Meanwhile, the surface softness performs a beneficial character in the short-range contribution for the adhesion of micropillars. Considering the fact that the soft microstructure and the almost totally wetting case (low surface tension of secretion and high surface energy of epidermis) on the pads of nature species, it is reasonable to suggest that these evolutions are in favor for wet attachments. PMID- 29190528 TI - Daily exceedance concentration hours: A novel indicator to measure acute cardiovascular effects of PM2.5 in six Chinese subtropical cities. AB - BACKGROUND: Daily mean concentration cannot fully address the hourly variations of air pollution within one day. As such, we proposed a new indicator, daily exceedance concentration hours (DECH), to explore the acute cardiovascular effects of ambient PM2.5 (particles with aerodynamic diameters less than 2.5MUm). The DECH in PM2.5 was defined as daily total concentration-hours >25MUg/m3. METHODS: A generalized additive model with a quasi-Poisson link was applied to estimate the associations between day-to-day variation in PM2.5 DECH and day-to day variation in cardiovascular mortality in six subtropical cities in Guangdong Province, China. RESULTS: The analysis revealed significant associations between PM2.5 DECHs and cardiovascular mortality. A 500MUg/m3*h increase in PM2.5 DECHs at lag03 was associated with an increase of 4.55% (95% confidence interval (CI): 3.59%, 5.52%) in cardiovascular mortality, 4.45% (95% CI: 2.81%, 6.12%) in ischemic cardiovascular mortality, 5.02% (95% CI: 3.41%, 6.65%) in cerebrovascular mortality, and 3.00% (95% CI: 1.13%, 4.90%) in acute myocardial infarction mortality. We further observed a greater mortality burden using PM2.5 DECHs than daily mean PM2.5 (6478 (95% CI: 5071, 7917) VS 5136 (95% CI: 3990, 6305)). CONCLUSION: This study reveals that PM2.5 DECH is one important exposure indicator of ambient PM2.5 to measure its cardiovascular mortality effects in Pearl River Delta region; and that using daily mean concentration could under estimate the mortality burden compared with this new indicator. PMID- 29190533 TI - Evaluating the critical strain energy release rate of bioactive glass coatings on Ti6Al4V substrates after degradation. AB - It has been reported that the adhesion of bioactive glass coatings to Ti6Al4V reduces after degradation, however, this effect has not been quantified. This paper uses bilayer double cantilever (DCB) specimens to determine GIC and GIIC, the critical mode I and mode II strain energy release rates, respectively, of bioactive coating/Ti6Al4V substrate systems degraded to different extents. Three borate-based bioactive glass coatings with increasing amounts of incorporated SrO (0, 15 and 25mol%) were enamelled onto Ti6Al4V substrates and then immersed in de ionized water for 2, 6 and 24h. The weight loss of each glass composition was measured and it was found that the dissolution rate significantly decreased with increasing SrO content. The extent of dissolution was consistent with the hypothesis that the compressive residual stress tends to reduce the dissolution rate of bioactive glasses. After drying, the bilayer DCB specimens were created and subjected to nearly mode I and mode II fracture tests. The toughest coating/substrate system (one composed of the glass containing 25mol% SrO) lost 80% and 85% of its GIC and GIIC, respectively, in less than 24h of degradation. The drop in GIC and GIIC occurred even more rapidly for other coating/substrate systems. Therefore, degradation of borate bioactive glass coatings is inversely related to their fracture toughness when coated onto Ti6A4V substrates. Finally, roughening the substrate was found to be inconsequential in increasing the toughness of the system as the fracture toughness was limited by the cohesive toughness of the glass itself. PMID- 29190529 TI - A review of emerging adsorbents and current demand for defluoridation of water: Bright future in water sustainability. AB - Fluoride contamination of groundwater is a serious problem in several countries of the world because of the intake of excessive fluoride caused by the drinking of the contaminated groundwater. Geological and anthropogenic factors are responsible for the contamination of groundwater with fluoride. Excess amounts of fluoride in potable water may cause irreversible demineralisation of bone and tooth tissues, a condition called fluorosis, and long-term damage to the brain, liver, thyroid, and kidney. There has long been a need for fluoride removal from potable water to make it safe for human use. From among several defluoridation technologies, adsorption is the technology most commonly used due to its cost effectiveness, ease of operation, and simple physical process. In this paper, the adsorption capacities and fluoride removal efficiencies of different types of adsorbents are compiled from relevant published data available in the literature and represented graphically. The most promising adsorbents tested so far from each category of adsorbents are also highlighted. There is still a need to discover the actual feasibility of usage of adsorbents in the field on a commercial scale and to define the reusability of adsorbents to reduce cost and the waste produced from the adsorption process. The present paper reviews the currently available methods and emerging approaches for defluoridation of water. PMID- 29190534 TI - Abundance and potential contribution of Gram-negative cheese rind bacteria from Austrian artisanal hard cheeses. AB - Many different Gram-negative bacteria have been shown to be present on cheese rinds. Their contribution to cheese ripening is however, only partially understood until now. Here, cheese rind samples were taken from Vorarlberger Bergkase (VB), an artisanal hard washed-rind cheese from Austria. Ripening cellars of two cheese production facilities in Austria were sampled at the day of production and after 14, 30, 90 and 160days of ripening. To obtain insights into the possible contribution of Advenella, Psychrobacter, and Psychroflexus to cheese ripening, we sequenced and analyzed the genomes of one strain of each genus isolated from VB cheese rinds. Additionally, quantitative PCRs (qPCRs) were performed to follow the abundance of Advenella, Psychrobacter, and Psychroflexus on VB rinds during ripening in both facilities. qPCR results showed that Psychrobacter was most abundant on cheese rinds and the abundance of Advenella decreased throughout the first month of ripening and increased significantly after 30days of ripening (p<0.01). Psychrobacter and Psychroflexus increased significantly during the first 30 ripening days (p<0.01), and decreased to their initial abundance during the rest of the ripening time (p<0.05). Genome sequencing resulted in 17 to 27 contigs with assembly sizes of 2.7 Mbp for Psychroflexus, 3 Mbp for Psychrobacter, and 4.3 Mbp for Advenella. Our results reveal that each genome harbors enzymes shown to be important for cheese ripening in other bacteria such as: Cystathionine/Methionine beta or gamma-lyases, many proteases and peptidases (including proline iminopeptidases), aminotransferases, and lipases. Thus, all three isolates have the potential to contribute positively to cheese ripening. In conclusion, the three species quantified were stable community members throughout the ripening process and their abundance on cheese rinds together with the results from genome sequencing suggest an important contribution of these bacteria to cheese ripening. PMID- 29190535 TI - Experiences of nursing undergraduates on a redesigned blended communication module: A descriptive qualitative study. AB - BACKGROUND: Education is going through accelerated changes to accommodate the needs of contemporary students. However, there are ongoing concerns regarding the quality of education in communication skills for nurses and other healthcare professionals. Many studies have been conducted to evaluate the effectiveness of a blended learning pedagogical tool in enhancing the learning of nursing undergraduates. However, little is known about students' experiences of a blended learning model for teaching communication skills. OBJECTIVE: To explore first year nursing students' experiences of the blended learning design adopted in a communication module. DESIGN: A descriptive qualitative design was adopted. SETTINGS AND PARTICIPANTS: Data were collected in the form of written reflections from 74 first year nursing undergraduates who were enrolled in a university affiliated nursing school. METHODS: Students were asked to complete an online reflective exercise regarding an undergraduate communication module on their last day of class, and the submitted reflections were analyzed. A thematic analysis was conducted and ethics approval was obtained for this study. RESULTS: Six overarching themes and fifteen subthemes were generated. The six overarching themes were: 1) Helpful and engaging classroom experience, 2) valuable online activities, 3) meaningful assessment, 4) appreciation for interprofessional education, 5) personal enrichment, and 6) overall feedback and recommendations. CONCLUSIONS: The students in this study felt that the blended pedagogy communication module enhanced their learning and boosted their confidence in facing similar situations. Interprofessional education was well-accepted among students as they attained a deeper understanding on the importance of interprofessional learning and an appreciation towards other professionals. Blended pedagogy can be used in teaching communication skills to nursing students to provide a holistic and up-to-date learning experience. Future studies should consider engaging students in face-to-face interviews to obtain a deeper understanding on their experiences of a blended pedagogy incorporated communication module. PMID- 29190531 TI - Effect of two-year degradation on mechanical interaction between a bioresorbable scaffold and blood vessel. AB - This paper aims to evaluate the mechanical behaviour of a bioresorbable polymeric coronary scaffold using finite element method, focusing on scaffold-artery interaction during degradation and vessel remodelling. A series of nonlinear stress-strain responses was constructed to match the experimental measurement of radial stiffness and strength for polymeric scaffolds over 2-year in-vitro degradation times. Degradation process was modelled by incorporating the change of material property as a function of time. Vessel remodelling was realised by changing the size of artery-plaque system manually, according to the clinical data in literature. Over degradation times, stress on the scaffold tended to increase firstly and then decreased gradually, corresponding to the changing yield stress of the scaffold material; whereas the stress on the plaque and arterial layers showed a continuous decrease. In addition, stress reduction was also observed for scaffold, plaque and artery in the simulations with the consideration of vessel remodelling. For the first time, the work offered insights into mechanical interaction between a bioresorbable scaffold and blood vessel during two-year in-vitro degradation, which has significance in assisting with further development of bioresorbable implants for treating cardiovascular diseases. PMID- 29190536 TI - State-level climate, anti-discrimination law, and sexual minority health status: An ecological study. AB - How social and legal climate influence LGB health is an under-studied topic. In response, this study examines whether the lesbian/gay/bisexual (LGB) climate index and presence of anti-discrimination law show population health significance for U.S. sexual minorities. The LGB climate index uses survey data collected between 2012 and 2013 to gauge states' support of lesbian, gay, and bisexual individuals, whereas anti-discrimination law captures any state-level law that makes it illegal to discriminate because of sexual orientation in employment, housing, and public accommodations. We merge these two contextual measures with 2011-2015 Behavioral Risk Factor Surveillance System (BRFSS) aggregated, individual-level survey data, from which we generate three measures of state level rates: excellent self-rated health, routine health care utilization, and health insurance among self-identified lesbian/gay and bisexual adults. We find that the LGB climate index associates positively with rates of excellent self rated health, routine health care utilization, and health insurance-but only for states with anti-discrimination laws, and only among lesbian/gay adults. Analyses confirm salubrious synergism between a sexually-minority-friendly climate and anti-discrimination law-together these two contextual measures interact to protect lesbian/gay population health. PMID- 29190537 TI - Private or public hospital ownership: Does it really matter? AB - Incentives to improve hospital performance under prospective payments may come at a cost. First, there may be a strong incentive for hospitals to choose only low severity patients. Second, hospitals may have an incentive to reduce the quality of care. I analyze the role of hospital ownership on patient selection and quality of care by comparing private nonprofit and public hospitals. The analysis is performed by using unique hospital admission data for cardiovascular procedures in Norway, covering the period from 1999 to 2006. Matching techniques are applied to control for patient heterogeneity. The econometric analyses are based on binary probit and ordinary least squares regression models. The results indicate that private nonprofit hospitals have specialized in certain procedures. These hospitals are also more likely to admit low-severity patients for some procedures. The association between quality of care and hospital ownership is mixed since private nonprofit hospitals both offer shorter waiting time and shorter length of stay. PMID- 29190538 TI - Research altruism as motivation for participation in community-centered environmental health research. AB - Protection of human subjects in research typically focuses on extrinsic rather than intrinsic motivations for participation in research. Recent sociological literature on altruism suggests that multiple kinds of altruism exist and are grounded in a sense of connection to common humanity. We interviewed participants in eight community-centered research studies that sampled for endocrine disrupting compounds and that shared research findings with participants. The results of our analysis of participation in these studies indicate that altruistic motivations were commonly held. We found that these sentiments were tied to feeling a sense of connection to society broadly, a sense of connection to science, or a sense of connection with the community partner organization. We develop a new concept of banal altruism to address mundane practices that work towards promoting social benefits. Further, we offer that research altruism is a specific type of banal altruism that is a multi-faceted and important reason for which individuals choose to participate in community-centered research. PMID- 29190541 TI - Comparison of moss and pine needles as bioindicators of transboundary polycyclic aromatic hydrocarbon pollution in central Japan. AB - Atmospheric pollution by polycyclic aromatic hydrocarbons (PAHs) has become a serious problem, especially in Asia, as PAHs can severely affect ecologically important mountainous areas. Using pine needles and mosses as bio-indicators, this study examined PAH pollution in a mountainous study area and evaluated the influence of transboundary PAHs. PAHs in urban areas were also evaluated for comparison. The study sites were alpine areas and urban areas (inland or coastal cities) across central Japan, in the easternmost part of Asia where atmospheric pollutants are transported from mainland Asia. The mean PAH concentrations of pine needles and mosses were 198.9 +/- 184.2 ng g-1 dry weight (dw) and 131.8 +/- 60.7 ng g-1 dw (mean +/- SD), respectively. Pine needles preferentially accumulated PAHs with low molecular weights (LMW PAHs) and exhibited large differences in both PAH concentration and isomer ratios between alpine and urban sites. These differences can be explained by the strong influence of LMW PAHs emitted from domestic sources, which decreased and changed during transport from urban to alpine sites due to dry/wet deposition and photodegradation. In contrast, mosses accumulated a higher ratio of PAHs with high molecular weight (HMW PAHs). A comparison of isomer ratios showed that the PAH source for alpine moss was similar to that for northern coastal cities, which are typically influenced by long-transported PAHs from East Asia. Thus, these results indicate that alpine moss can also be strongly affected by the transboundary PAHs. It is likely that the uptake characteristics of moss, alpine climate, and alpine locations far from urban areas can strengthen the influence of transboundary pollution. Based on these results, the limitations and most effective use of bioindicators of PAH pollution for preserving alpine ecosystems are discussed. PMID- 29190539 TI - Dysbiosis of gut microbiota by chronic coexposure to titanium dioxide nanoparticles and bisphenol A: Implications for host health in zebrafish. AB - Gut microbiota is of critical relevance to host health. However, toxicological understanding of environmental pollutants on gut microbiota is limited, not to mention their combined effects. In the present study, adult zebrafish (Danio rerio) were exposed to titanium dioxide nanoparticles (nano-TiO2; 100 MUg/L), bisphenol A (BPA; 0, 2, and 20 MUg/L) or their binary mixtures for three months. Sequencing of 16S rRNA amplicons found that nano-TiO2 and BPA coexposure shifted the intestinal microbial community, interacting in an antagonistic manner when the BPA concentration was low but in a synergistic manner at a higher BPA concentration. Sex- and concentration-dependent responses to the coexposure regime were also observed for zebrafish growth and intestinal health (e.g. neurotransmission, epithelial barrier permeability, inflammation, and oxidative stress). Correlation analysis showed that oxidative stress after nano-TiO2 and BPA coexposure was tightly associated with the imbalanced ratio of pathogenic Lawsonia and normal metabolic Hyphomicrobium, where higher abundance of Lawsonia but lower abundance of Hyphomicrobium were induced concurrently. A positive relationship was observed between zebrafish body weight and the abundance of Bacteroides in the gut, which was also closely associated with the genera of Anaerococcus, Finegoldia, and Peptoniphilus. This study revealed, for the first time, the combined effects of nano-TiO2 and BPA coexposure on the dynamics of the gut microbiome, which proved to have toxicological implications for zebrafish host health. PMID- 29190544 TI - The contribution of occupational factors on frailty. AB - INTRODUCTION: Frailty is a clinical condition characterized by enhanced vulnerability to stressors and increased risk of developing dependency and/or mortality. It has been described as the multidimensional and dynamic condition that cannot be easily disentangled from psychosocial determinants. To date, the possible role of occupational factors on frailty development and its progression at advanced age are not yet fully understood. The aim of this work is to provide a comprehensive overview of existing evidence exploring the relationship between multiple occupational issues (e.g., employment history, workplace risk factors, organizational job characteristics) and frailty. METHODS: A systematic search and revision of available literature addressing the contribution of occupational factors on the quantitative and qualitative aspects of frailty in the elderly was performed in the Pubmed, Scopus, and ISI Web of Science databases. RESULTS: The major weaknesses of existing literature reside in the heterogeneous operationalization of frailty and the limited description of the workplace factors. Nevertheless, an association between life-course occupational conditions and frailty was documented. In particular, intrinsically harder, manual, or blue collar occupations emerged as possible determinants of the frailty manifestation and severity at older age. CONCLUSIONS: Our preliminary results do not allow extrapolating definite conclusions. Further studies are needed. However, it seems that a significant relationship exists between the life-course occupation and frailty at advanced age. From a public health and social geriatric perspective, this work may provide the basis to define future innovations for preventing frailty at elderly adopting a life-course approach. PMID- 29190542 TI - Reference values and equations reference of balance for children of 8 to 12 years. AB - PURPOSE: There are still no normative data in balance sway for school-age children in Brazil. We aimed to establish the reference ranges for balance scores and to develop prediction equations for estimation of balance scores in children aged 8 to 12 years old. METHODS: The study included 165 healthy children (83 boys and 82 girls; age, 8-12 years) recruited from a public school in the city of Florianopolis, Santa Catarina, Brazil. We used the Sensory Organization Test to assess the balance scores and both a digital scale and a stadiometer to measure the anthropometric variables. We tested a stepwise multiple-regression model with sex, height, weight, and mid-thigh circumference of the dominant leg as predictors of the balance score. RESULTS: For all experimental conditions, girls' age accounted for over 85% of the variability in balance scores; while, boys' age accounted only 55% of the variability in balance scores. Therefore, balance scores increase with age for boys and girls. CONCLUSION: This study described the ranges of age- and sex-specific normative values for balance scores in children during 6 different testing conditions established by the sensory organization test. We confirmed that age was the predictor that best explained the variability in balance scores in children between 8 and 12 years old. This study stimulates a new and more comprehensive study to estimate balance scores from prediction equations for overall Brazilian pediatric population. PMID- 29190540 TI - Impact of cold temperature on Euro 6 passenger car emissions. AB - Hydrocarbons, CO, NOx, NH3, N2O, CO2 and particulate matter emissions affect air quality, global warming and human health. Transport sector is an important source of these pollutants and high pollution episodes are often experienced during the cold season. However, EU vehicle emissions regulation at cold ambient temperature only addresses hydrocarbons and CO vehicular emissions. For that reason, we have studied the impact that cold ambient temperatures have on Euro 6 diesel and spark ignition (including: gasoline, ethanol flex-fuel and hybrid vehicles) vehicle emissions using the World-harmonized Light-duty Test Cycle (WLTC) at -7 degrees C and 23 degrees C. Results indicate that when facing the WLTC at 23 degrees C the tested vehicles present emissions below the values set for type approval of Euro 6 vehicles (still using NEDC), with the exception of NOx emissions from diesel vehicles that were 2.3-6 times higher than Euro 6 standards. However, emissions disproportionally increased when vehicles were tested at cold ambient temperature (-7 degrees C). High solid particle number (SPN) emissions (>1 * 1011 # km-1) were measured from gasoline direct injection (GDI) vehicles and gasoline port fuel injection vehicles. However, only diesel and GDI SPN emissions are currently regulated. Results show the need for a new, technology independent, procedure that enables the authorities to assess pollutant emissions from vehicles at cold ambient temperatures. Harmful pollutant emissions from spark ignition and diesel vehicles are strongly and negatively affected by cold ambient temperatures. Only hydrocarbon, CO emissions are currently regulated at cold temperature. Therefore, it is of great importance to revise current EU winter vehicle emissions regulation. PMID- 29190545 TI - Six weeks of combined aerobic and resistance exercise using outdoor exercise machines improves fitness, insulin resistance, and chemerin in the Korean elderly: A pilot randomized controlled trial. AB - BACKGROUND: The aim of this study was to investigate the effect of a six-week long exercise program using outdoor exercise equipment on fitness, insulin resistance and adipocytokines among Korean elderly. METHODS: A total of 47 participants were randomized into one of the following three groups; control, resistance exercise or combined exercise (aerobic and resistance exercise). The resistance exercise group completed three resistance types of exercise. The combined exercise group completed five exercises, including three resistance types of exercise and two aerobic types of exercise. Participants' body composition, fitness level, homeostasis model assessment of insulin resistance (HOMA-IR), and adipocytokines were measured at baseline and at the end of six weeks. RESULTS: After six weeks of exercise training, participants in the combined exercise group exhibited significant reduction in insulin, HOMA-IR and chemerin levels, while significant reduction was observed in HOMA-IR only in the resistance exercise group compared with the control group. Meanwhile, six weeks of exercise training, whether resistance exercise alone or combined, significantly improved upper body muscular strength/endurance and physical function compared to the control group. CONCLUSIONS: Six weeks of combined exercise using outdoor exercise equipment was effective in improving fitness, HOMA-IR, circulating chemerin levels, and other known risk factors of chronic diseases. PMID- 29190547 TI - Low-folate stress reprograms cancer stem cell-like potentials and bioenergetics metabolism through activation of mTOR signaling pathway to promote in vitro invasion and in vivo tumorigenicity of lung cancers. AB - Low-folate (LF) nutritional status is associated with increased risks of lung cancer. It has unexplored effects on lung cancer malignancy, a cancer stem cell (CSC) disease. We hypothesized that LF may reprogram CSC-like potential and bioenergetics metabolism to increase metastasis potential of lung cancers. Cultivation of human non-small-cell lung cancer cells (H23) in an LF medium enhanced CSC-like properties signified by increased expressions of the CSC surface marker CD44 and pluripotency markers Sox2, Oct4 and ALDH1A1, and promoted self-renewal ability of anchorage-independent oncospheroid formation. The CSC like phenotype of LF-treated H23 cells coupled with the metabolic reprogramming to aerobic glycolysis evident by elevated lactate release and medium acidification suppressed expressions of pyruvate dehydrogenase E1-alpha, and elevated redox status of the NADH/NAD+ and NADPH/NADP+ ratios. The LF-induced metabostemness phenotype of H23 cells was modified by DNA methylation inhibitor 5 AdC and histone acetylation inhibitor EX. Treatment of H23 cells with mTOR siRNA or the mTOR inhibitor rapamycin abrogated LF-activated Akt-mTOR-Hif1-Foxo signaling and stemness-associated sonic hedgehog pathway, reversed Warburg metabolic switch and diminished invasion of H23 cells. Intrapleural injection of LF-induced lung oncospheres into the LF recipient mice, but not the control recipient mice, caused metastasis xenograft lung tumors. The in vitro and in vivo data corroboratively demonstrate that LF stress reprograms metabostemness signatures through activated mTOR signaling pathway to promote metastasis tumorigenicity of lung cancers. PMID- 29190548 TI - Supplementation with polyunsaturated fatty acids in pregnant rats with mild diabetes normalizes placental PPARgamma and mTOR signaling in female offspring developing gestational diabetes. AB - Maternal diabetes impairs fetoplacental development and programs metabolic diseases in the offspring. We have previously reported that female offspring of pregnant rats with mild diabetes develop gestational diabetes mellitus (GDM) when they become pregnant. Here, we studied the effects of supplementation with polyunsaturated fatty acids (PUFAs) in pregnant mild diabetic rats (F0) by feeding a 6% safflower-oil-enriched diet from day 1 to 14 followed by a 6% chia oil-enriched diet from day 14 of pregnancy to term. We analyzed maternal metabolic parameters and placental signaling at term in pregnant offspring (F1). The offspring of both PUFAs-treated and untreated mild diabetic rats developed GDM. Although gestational hyperglycemia was not prevented by dietary PUFAs treatment in F0, triglyceridemia and cholesterolemia in F1 mothers were normalized by F0 PUFAs dietary treatment. In the placenta of F1 GDM rats, PPARgamma levels were reduced and lipoperoxidation was increased, changes that were prevented by the maternal diets enriched in PUFAs in the F0 generation. Moreover, fetal overgrowth and placental activation of mTOR signaling pathways were reduced in F1 GDM rats whose mothers were treated with PUFAs diets. These results suggest that F0 PUFAs dietary treatment in pregnancies with mild diabetes improves maternal dyslipidemia, fetal overgrowth and placental signaling in female offspring when they become pregnant. We speculate that an increased PUFAs intake in pregnancies complicated by diabetes may prove effective to ameliorate metabolic programming in the offspring, thereby improving the health of future generations. PMID- 29190546 TI - Age related changes in balance performance during self-selected and narrow stance testing. AB - BACKGROUND: Various balance tests have been considered as fall risk screening tools however there is a lot of variability in the methods and outcome measures reported. Based on previous research examining age-related changes in balance and differences between fallers and nonfallers, the purpose of this investigation was to examine age-related balance changes, as reflected in medial-lateral center of pressure (CP) velocity, in community-dwelling/independently living adults (>=60years) during self-selected and narrow stance testing with eyes opened and closed. METHODS: Two hundred and thirty adults aged 60yrs or older completed one 45s trial under two stances (self-selected, narrow) and two visual conditions (eyes opened, eyes closed). Average medial-lateral CP velocity was computed from the CP data, with preliminary analysis demonstrating positive skewness and association with body height. A sway velocity index (SVI) was created by a natural logarithm transformation and dividing by body height. Multiple linear regression was used to determine the association between age, visual condition, stance, and sex with SVI. RESULTS: Age, visual condition, stance and sex were all demonstrated to be significant predictors of SVI, with the combination of the predictors explaining 25% of the variance in the SVI. CONCLUSIONS: These results confirm the balance testing protocol and SVI to be sensitive to age-related changes in balance performance. The results of this study should help future research aimed towards establishing a quick, easy to administer, and readily interpretable instrumented test for assisting with identifying potential balance impairments in older adults who have yet to demonstrate outward deficits. PMID- 29190549 TI - Cholesterol oversynthesis markers define familial combined hyperlipidemia versus other genetic hypercholesterolemias independently of body weight. AB - Primary hypercholesterolemia of genetic origin, negative for mutations in LDLR, APOB, PCSK9 and APOE genes (non-FH GH), and familial combined hyperlipidemia (FCHL) are polygenic genetic diseases that occur with hypercholesterolemia, and both share a very high cardiovascular risk. In order to better characterize the metabolic abnormalities associated with these primary hypercholesterolemias, we used noncholesterol sterols, as markers of cholesterol metabolism, to determine their potential differences. Hepatic cholesterol synthesis markers (desmosterol and lanosterol) and intestinal cholesterol absorption markers (sitosterol and campesterol) were determined in non-FH GH (n=200), FCHL (n=100) and genetically defined heterozygous familial hypercholesterolemia subjects (FH) (n=100) and in normolipidemic controls (n=100). FCHL subjects had lower cholesterol absorption and higher cholesterol synthesis than non-FH GH, FH and controls (P<.001). When noncholesterol sterols were adjusted by body mass index (BMI), FCHL subjects had higher cholesterol synthesis than non-FG GH, FH and controls (P<.001). An increase in BMI was accompanied by increased cholesterol synthesis and decreased cholesterol absorption in non-FH GH, FH and controls. However, this association between BMI and cholesterol synthesis was not observed in FCHL. Non-high-density lipoprotein cholesterol showed a positive correlation with cholesterol synthesis markers similar to that of BMI in non-FH GH, FH and normolipemic controls, but there was no correlation in FCHL. These results suggest that FCHL and non-FH GH have different mechanisms of production. Cholesterol synthesis and absorption are dependent of BMI in non-FH GH, but cholesterol synthesis is increased as a pathogenic mechanism in FCHL independently of age, gender, APOE and BMI. PMID- 29190553 TI - Sewage sludge as a soil amendment in a Larix decidua plantation: Effects on tree growth and floristic diversity. AB - Sewage sludge application in forest plantations is an interesting complementary alternative practice to sewage sludge reutilization and recycling, with a significant and sustainable net effect in climate change mitigation. However, to optimize it a detailed knowledge of its effects on ecosystem components such as plants, soil, water and fauna is needed. We investigated the effects of sewage sludge application on soil, tree growth and floristic diversity in a ten-year-old plantation of European larch (Larix decidua Mill.). Our one-hectare study site, located at Melisey, Haute-Saone, France (47 degrees 753' Lat., 6 degrees 580' Long.), was subdivided into six plots. Three plots, alternating with three control plots (no sewage sludge application), were amended in June 2008 with 0.4tDWha-1 obtained from a municipal urban wastewater treatment plant in Melisey. Within each plot, one subplot was delimited and sludge was again manually applied at 3t of DWha-1 in July 2009 and March 2010 to the soil surface of the amended subplots without incorporation. The results showed no effect on radial and height growth of European larch amended with 0.4tDWha-1. While a significant temporary increase in pH, macro-element contents (N, P and Ca) and the trace metal (Cu and Zn) concentration in the soil was observed, it had no significant effect on needles and sporocarp contents. The number of species in the amended subplots with 3tDWha-1year-1 increased by 80% compared to the control. However, the relative species abundance present only in amended subplots remains <1, except for Hypericum humifusum. PMID- 29190550 TI - Green tea extract protects against hepatic NFkappaB activation along the gut liver axis in diet-induced obese mice with nonalcoholic steatohepatitis by reducing endotoxin and TLR4/MyD88 signaling. AB - Green tea extract (GTE) reduces NFkappaB-mediated inflammation during nonalcoholic steatohepatitis (NASH). We hypothesized that its anti-inflammatory activities would be mediated in a Toll-like receptor 4 (TLR4)-dependent manner. Wild-type (WT) and loss-of-function TLR4-mutant (TLR4m) mice were fed a high-fat diet containing GTE at 0 or 2% for 8 weeks before assessing NASH, NFkappaB mediated inflammation, TLR4 and its adaptor proteins MyD88 and TRIF, circulating endotoxin, and intestinal tight junction protein mRNA expression. TLR4m mice had lower (P<.05) body mass compared with WT mice but similar adiposity, whereas body mass and adiposity were lowered by GTE regardless of genotype. Liver steatosis, serum alanine aminotransferase, and hepatic lipid peroxidation were also lowered by GTE in WT mice, and were similarly lowered in TLR4m mice regardless of GTE. Phosphorylation of the NFkappaB p65 subunit and pro-inflammatory genes (TNFalpha, iNOS, MCP-1, MPO) were lowered by GTE in WT mice, and did not differ from the lowered levels in TLR4m mice regardless of GTE. TLR4m mice had lower TLR4 mRNA, which was also lowered by GTE in both genotypes. TRIF expression was unaffected by genotype and GTE, whereas MyD88 was lower in mice fed GTE regardless of genotype. Serum endotoxin was similarly lowered by GTE regardless of genotype. Tight junction protein mRNA levels were unaffected by genotype. However, GTE similarly increased claudin-1 mRNA in the duodenum and jejunum and mRNA levels of occludin and zonula occluden-1 in the jejunum and ileum. Thus, GTE protects against inflammation during NASH, likely by limiting gut-derived endotoxin translocation and TLR4/MyD88/NFkappaB activation. PMID- 29190551 TI - Predictors and correlations of phthalate metabolite concentrations in urine and seminal plasma among reproductive-aged men. AB - BACKGROUND: Certain phthalates are suspected to be endocrine disruptors that are adversely associated with male reproductive health. However, the predictors and correlations of phthalate metabolite concentrations in urine and seminal plasma among reproductive-aged men have not been thoroughly studied. OBJECTIVE: To investigate the predictors and correlations of phthalate metabolite concentrations in urine and seminal plasma among adult Chinese males. METHOD: We measured mono-n-butyl phthalate (MBP), monobenzyl phthalate (MBzP), monomethyl phthalate (MMP), monoethyl phthalate (MEP), mono-n-octyl phthalate (MOP), mono(2 ethylhexyl) phthalate (MEHP), mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and mono(2-ethyl-5-oxohexyl) phthalate (MEOHP) concentrations in seminal plasma and repeated spot-urine samples from 687 men who visited a reproductive center. Mixed effect models were used to examine the associations of sociodemographic, lifestyle and medical factors with urinary metabolite concentrations. Linear regression models were used to identify predictors of metabolite concentrations in seminal plasma and correlations between metabolite concentrations in spot urine samples and seminal plasma. RESULTS: Measurements taken from spot urine samples poorly predicted same-day seminal plasma concentrations (all R2<0.10). Inverse associations were observed between education level and urinary MBP and MEOHP and between household income and urinary MMP; receiving intravenous infusion therapy was associated with increased urinary MBP, MEHHP and MEOHP, use of facial cleanser/cream was associated with increased MEP, and smoking was associated with increased MEHP. The predictors of metabolite concentrations in seminal plasma differed from those in urine, except for the association of intravenous infusion therapy with MBP. BMI was associated with increased seminal plasma MBP, MEHP and MEOHP, smoking was associated with increased MEP, and contact with plastics was associated with increased MEOHP. CONCLUSIONS: Phthalate metabolite concentrations in adult men varied in accordance with sociodemographic variables, lifestyle factors and intravenous therapy. Measures of metabolite levels in urine may not directly reflect the exposure status of the male reproductive system. PMID- 29190556 TI - Null-space Monte Carlo particle tracking to assess groundwater PCE (Tetrachloroethene) diffuse pollution in north-eastern Milan functional urban area. AB - The Lombardy Region in Italy is one of the most urbanized and industrialized areas in Europe. The presence of countless sources of groundwater pollution is therefore a matter of environmental concern. The sources of groundwater contamination can be classified into two different categories: 1) Point Sources (PS), which correspond to areas releasing plumes of high concentrations (i.e. hot spots) and 2) Multiple-Point Sources (MPS) consisting in a series of unidentifiable small sources clustered within large areas, generating an anthropogenic diffuse contamination. The latter category frequently predominates in European Functional Urban Areas (FUA) and cannot be managed through standard remediation techniques, mainly because detecting the many different source areas releasing small contaminant mass in groundwater is unfeasible. A specific legislative action has been recently enacted at Regional level (DGR IX/3510 2012), in order to identify areas prone to anthropogenic diffuse pollution and their level of contamination. With a view to defining a management plan, it is necessary to find where MPS are most likely positioned. This paper describes a methodology devised to identify the areas with the highest likelihood to host potential MPS. A groundwater flow model was implemented for a pilot area located in the Milan FUA and through the PEST code, a Null-Space Monte Carlo method was applied in order to generate a suite of several hundred hydraulic conductivity field realizations, each maintaining the model in a calibrated state and each consistent with the modelers' expert-knowledge. Thereafter, the MODPATH code was applied to generate back-traced advective flowpaths for each of the models built using the conductivity field realizations. Maps were then created displaying the number of backtracked particles that crossed each model cell in each stochastic calibrated model. The result is considered to be representative of the FUAs areas with the highest likelihood to host MPS responsible for diffuse contamination. PMID- 29190555 TI - Sources and distribution of yttrium and rare earth elements in surface sediments from Tagus estuary, Portugal. AB - The distribution and sources of yttrium and rare-earth elements (YREE) in surface sediments were studied on 78 samples collected in the Tagus estuary (SW Portugal, SW Europe). Yttrium and total REE contents ranged from 2.4 to 32mg.kg-1 and 18 to 210mg.kg-1, respectively, and exhibited significant correlations with sediment grain-size, Al, Fe, Mg and Mn, suggesting a preferential association to fine grained material (e.g. aluminosilicates but also Al hydroxides and Fe oxyhydroxides). The PAAS (Post-Archean Australian Shale) normalized patterns display three distinct YREE fractionation pattern groups along the Tagus estuary: a first group, characterized by medium to coarse-grained material, a depleted and almost flat PAAS-normalized pattern, with a positive anomaly of Eu, representing one of the lithogenic components; a second group, characterized mainly by fine grained sediment, with higher shale-normalized ratios and an enrichment of LREE relative to HREE, associated with waste water treatment plant (WWTP) outfalls, located in the northern margin; and, a third group, of fine-grained material, marked by a significant enrichment of Y, a depletion of Ce and an enrichment of HREE over LREE, located near an inactive chemical-industrial complex (e.g. pyrite roast plant, chemical and phosphorous fertilizer industries), in the southern margin. The data allow the quantification of the YREE contents and its spatial distribution in the surface sediments of the Tagus estuary, identifying the main potential sources and confirming the use of rare earth elements as tracers of anthropogenic activities in highly hydrodynamic estuaries. PMID- 29190552 TI - Evaluation of local anesthetic effects of Lidocaine-Ibuprofen ionic liquid stabilized silver nanoparticles in Male Swiss mice. AB - A simple approach for the synthesis of Lidocaine-Ibuprofen ionic liquid stabilized silver nanoparticles (IL-AgNPs) was reported in this work. The shape, size and surface morphology of the Lidocaine-Ibuprofen ionic liquid stabilized AgNPs were characterized by using spectroscopic and microscopic techniques such as Ultraviolet-visible spectroscopy (UV-Visible), X-ray diffraction (XRD) analysis, Selected area electron diffraction (SAED), Transmission electron microscopy (TEM). TEM analysis showed the formation of 20-30nm size of IL-AgNPs with very clear lattice fringes. SAED pattern confirmed the highly crystalline nature of fabricated IL stabilized AgNPs. EDS results confirmed the formation of nanosilver. The fabricated IL-AgNPs were studied for their local anesthetic effect in rats. The results of local anesthetic effect showed that the time for onset of action by IL-AgNPs is 10min, which is significantly higher than that for EMLA. Further, tactile test results confirmed the stronger and faster local anesthetic effect of IL-AgNPs when compared to that of EMLA. PMID- 29190554 TI - A potential microRNA regulation of immune-related genes in invertebrate haemocytes. AB - Bivalve mollusks have been employed as sentinel organisms in environmental health programs due to their sedentary lifestyle, filter-feeding behavior and their ability to accumulate pathogens or toxin molecules inside tissues. Endocrine disrupting chemicals (EDCs) can be up taken and bioaccumulated, and due to sensibility of mollusks to these EDCs, being able to cause immune alterations. Recently, microRNAs (miRNAs) were shown to be involved in modulation and buffering developmental processes against the effects of environmental alterations and pathogenic microorganisms. Moreover, it is suggested that this miRNAs are incorporated into the estrogen-controlled immune network, regulating mechanism of immune gene expression at the posttranscriptional level, modulating immune responses as phagocytosis, redox reaction and apoptosis in bivalve haemocytes. Thus, miRNAs can be used as biomarkers that specifically elucidate immunotoxic effects caused by exogenous biotic or abiotic factors, and can act as useful tools in integrated monitoring environmental health programs. In this review, we aim to describe the investigations that have been carried out on miRNAs in bivalve mollusks, especially those associated with immune responses against infectious agents and xenobiotic exposure. PMID- 29190557 TI - Prenatal co-exposure to neurotoxic metals and neurodevelopment in preschool children: The Environment and Childhood (INMA) Project. AB - We sought to determine whether prenatal co-exposure to As, Cd, Hg, Mn, and Pb was associated with impaired neurodevelopment in preschool children from the Spanish Environment and Childhood (INMA) Project, using the placenta as exposure matrix. We measured metal levels in placenta tissue samples randomly selected from five of the seven population-based birth cohorts participating in the INMA Project, collected between 2000 and 2008. Neuropsychological assessment of cognitive and motor function was carried through the use of the McCarthy Scales of Children's Abilities (MSCA) at the age of 4-5years. Data on placental metal levels, MSCA scores, and relevant covariates was available for 302 children. Mn was detected in all placental samples, Cd in nearly all placentas (99%) and As, Hg, and Pb in 22%, 58%, and 17% of the placentas, respectively. After adjusting for potential confounders, detectable As levels were associated with decrements in global and verbal executive functions and quantitative abilities; detectable Hg was associated with lower scores on the verbal function of posterior cortex in a dose response manner, and non-linearly related to poorer motor function and gross motor skills; and Mn levels were associated with decrement in perceptual performance skills in a dose-response manner but with better memory span and quantitative skills. A synergistic interactive effect was found between As and Pb with respect to the general cognitive score, whereas an antagonistic interaction was found between Mn and Hg. Prenatal exposure to As and Hg may be a risk factor for cognitive and motor impairment in children, while the effects of Cd and Mn on neurodevelopment are less clear. Future studies should examine combined and interactive effects of exposure to multiple metals during vulnerable periods of brain development prospectively. PMID- 29190561 TI - Labile and stable soil organic carbon and physical improvements using groundcovers in vineyards from central Spain. AB - Mediterranean vineyards are usually managed with continuous tillage to maintain bare soils leading to low organic matter stocks and soil degradation. Vineyards are part of the Mediterranean culture, their management can be sustainable. We propose the setup of two types of groundcovers with the aim to assess their potential influence to improve soil properties. A field trial was performed to compare the effects of a seeded (Brachypodium distachyon) and spontaneous groundcovers, on a set of soil parameters, in comparison with the traditional tillage in four vineyards located in the center of Spain. Three years after the groundcovers establishment soil organic carbon stocks increased up to 1.62 and 3.18Mgha-1 for the seeded and the spontaneous groundcovers, respectively, compared to conventional tillage. Both labile and stable fractions improved their soil organic carbon content with the use of groundcovers, particularly the labile fraction. Moreover, soil structure and functional soil properties improved through better aggregate stability, pore connectivity and infiltration rates. The higher root biomass input of the spontaneous groundcovers derived in higher soil organic carbon increases and soil quality improvement. Consequently, under low rainfall conditions (<400mmperyear) spontaneous vegetation, properly managed according to site conditions, is an effective soil management strategy to revert soil degradation and increase soil quality in Mediterranean vineyards.

AB - Re-establishing submerged vegetation is considered an important tool to restore shallow eutrophic lakes. A whole year comparative field study was performed in a eutrophic lake and its connected pond with Potamogeton crispus in order to determine the effects of the growth and senescence of submerged macrophytes on structure of phytoplankton. P. crispus improved the water quality at the growing season in terms of improving transparency, decreasing total phosphorus, soluble reactive phosphorus (SRP) and chlorophyll a concentrations and slowering turnover rate of dissolved organic phosphorus (DOP). Meanwhile, dominant species shift from Chlorophyta to Diatom. Notably, senescence and decomposition of P. crispus in late spring resulted in an abrupt increase of DOP, providing a suitable growing environment for Euglena and dinoflagellates and a Peridiniopsis bloom occurred owing to their advantage in utilizing DOP. Peridiniopsis excreted phosphatase as evidence by simultaneously in situ enzyme labelled fluorescence (ELF) labelling and main alkaline phosphatase activity contributed by large particles, suggesting that the dominance of dinoflagellate with low SRP is enabled by its ability to efficiently hydrolyze DOP. Under the scenario of worldwide application of re-establishing submerged vegetation, our results provide the evidence of the negative environmental effects that occurred when transplanting P. crispus to recover a eutrophic lake.

AB - Inflammation is a common hallmark of neurodegenerative disorders. Systemic inflammation is usually associated with cognitive deficits. Scutellarin is a flavone with established antioxidant, anti-inflammatory, and neuroprotective effects. In this study, the effect of this flavone in prevention of lipopolysaccharide (LPS)-induced cognitive deficit was evaluated. LPS was i.p. injected at a dose of 500MUg/kg/day and scutellarin was administered i.p. at doses of 5, 25, or 50mg/kg/day. Treatment of LPS-injected rats with scutellarin dose-dependently ameliorated deficits of spatial recognition memory in Y maze, discrimination index in novel object discrimination task, and retention and recall index in passive avoidance test. Additionally, scutellarin lowered hippocampal malondialdehyde (MDA) and potentiated antioxidant defense elements comprising superoxide dismutase (SOD), catalase, and glutathione (GSH) in addition to reduction of acetylcholinesterase (AChE) activity. Furthermore, scutellarin decreased hippocampal nuclear factor-kappaB (NF-kappaB), tumor necrosis factor alpha (TNFalpha), interleukin 6 (IL-6) and elevated nuclear factor (erythroid-derived 2)-like 2 (Nrf2). Inappropriate alterations of authophagy markers including beclin-1, LC3 II, mTOR, and P62 were also prevented in the presence of scutellarin. Our findings demonstrate that scutellarin alleviates LPS-induced cognitive disturbances, however, the precise mechanism remains still speculative. PMID- 29190560 TI - Methylmercury complexes: Selection of thermodynamic properties and application to the modelling of a column experiment. AB - Complexation with methyl groups produces the most toxic form of mercury, especially because of its capacity to bioconcentrate in living tissues. Understanding and integrating methylation and demethylation processes is of the utmost interest in providing geochemical models relevant for environmental assessment. In a first step, we investigated methylation at equilibrium, by selecting the thermodynamic properties of different complexes that form in the chemical system Hg-SO3-S-Cl-C-H2O. The selection included temperature dependencies of the equilibrium constants when available. We also considered adsorption and desorption reactions of both methylated and non-methylated mercury onto mineral surfaces. Then we assessed the kinetics of methylation by comparing a dedicated column experiment with the results of a geochemical model, including testing different methylation and demethylation kinetic rate laws. The column system was a simple medium: silicic sand and iron hydroxides spiked with a mercury nitrate solution. The modelling of methylmercury production with two different rate laws from the literature is bracketing the experimental results. Dissolved mercury, iron and sulfate concentrations were also correctly reproduced. The internal evolution of the column was also correctly modeled, including the precipitation of mackinawite (FeS) and the evolution of dissolved iron. The results validate the conceptual model and underline the capacity of geochemical models to reproduce some processes driven by bacterial activity. PMID- 29190558 TI - Factors controlling the three-decade long rise in cyanobacteria biomass in a eutrophic shallow lake. AB - We aimed at quantifying the importance of limnological variables in the decadal rise of cyanobacteria biomass in shallow hemiboreal lakes. We constructed estimates of cyanobacteria (blue-green algae) biomass in a large, eutrophic lake (Estonia, Northeastern Europe) from a database comprising 28 limnological variables and spanning more than 50years of monitoring. Using a dual-model approach consisting in a boosted regression trees (BRT) followed by a generalized least squares (GLS) model, our results revealed that six variables were most influential for assessing the variance of cyanobacteria biomass. Cyanobacteria response to nitrate concentration and rotifer abundance was negative, whereas it was positive to pH, temperature, cladoceran and copepod biomass. Response to total phosphorus (TP) and total phosphorus to total nitrogen ratio was very weak, which suggests that actual in-lake TP concentration is still above limiting values. The most efficient GLS model, which explained nearly two thirds (r2=0.65) of the variance of cyanobacteria biomass included nitrate concentration, water temperature and pH. The very high number of observations (maximum n=525) supports the robustness of the models. Our results suggest that the decadal rise of blue green algae in shallow lakes lies in the interaction between cultural eutrophication and global warming which bring in-lake physical and chemical conditions closer to cyanobacteria optima. PMID- 29190562 TI - Indoor thermal environment, air exchange rates, and carbon dioxide concentrations before and after energy retro fits in Finnish and Lithuanian multi-family buildings. AB - Impacts of energy retrofits on indoor thermal environment, i.e. temperature (T) and relative humidity (RH), as well as ventilation rates and carbon dioxide (CO2) concentrations, were assessed in 46 Finnish and 20 Lithuanian multi-family buildings, including 39 retrofitted case buildings in Finland and 15 in Lithuania (the remaining buildings were control buildings with no retrofits). In the Finnish buildings, high indoor T along with low RH levels was commonly observed both before and after the retrofits. Ventilation rates (l/s per person) were higher after the retrofits in buildings with mechanical exhaust ventilation than the corresponding values before the retrofits. Measured CO2 levels were low in vast majority of buildings. In Lithuania, average indoor T levels were low before the retrofits and there was a significant increase in the average T after the retrofits. In addition, average ventilation rate was lower and CO2 levels were higher after the retrofits in the case buildings (N=15), both in apartments with natural and mixed ventilation. Based on the results, assessment of thermal conditions and ventilation rates after energy retrofits is crucial for optimal indoor environmental quality and energy use. PMID- 29190563 TI - Institutional impediments to conservation of freshwater dependent ecosystems. AB - When freshwater resources become scarce there is a trade-off between human resource demands and environmental sustainability. The cost of conserving freshwater ecosystems can potentially be reduced by implementing institutional reforms that endow environmental water managers with a permanent water entitlement and the capacity to store, trade and release water. Australia's Murray Darling Basin Plan (MDBP) includes one of the world's most ambitious programs to recover water for the environment, supported by institutional reforms that allow environmental water managers to operate in water markets. One of the anticipated benefits of the Plan is to improve the health of flood-dependent forests, which are among the most endangered ecosystems globally because of river regulation and land clearance. However, periodic flooding to conserve floodplain ecosystems in the MDB creates losses to riparian landowners such as damage to fencing and temporary loss of access to flooded land. To reduce these losses reservoir operators restrict daily water release volumes. Using a model of optimal water management in Australia's southern MDB we estimate that current reservoir operating restrictions will substantially reduce the ecological benefits of investments made to recover water for the environment. The reduction in benefits is largest if floodplain forests decline rapidly without periodic inundation. In the latter circumstances, ecological losses cannot significantly be reduced by allowing environmental water managers to operate in water markets. Our findings demonstrate that the recovery of large volumes of water for environmental purposes and water market reforms are insufficient for conserving flood-dependent ecosystems without coordination and cooperation among multiple stakeholders responsible for water and land management. PMID- 29190564 TI - Application of microwave-pretreated cephalosporin mycelial dreg (CMD) as soil amendment: Temporal changes in chemical and fluorescent parameters of soil organic matter. AB - Land application of treated cephalosporin mycelial dreg (CMD) as a soil amendment is an alternative to its disposal in landfills and incineration because it has environmental and agronomic benefits. This study validated the efficacy of using the dewatered, microwave-pretreated CMD as a soil amendment. Pot experiments were conducted to assess the temporal changes in soil organic matter (SOM) profiles via chemical and fluorescent parameters. During the ageing period, the CMD treated soil experienced a sudden rise in soil pH and soil electrical conductivity, along with a rapid decline in soil organic carbon and soil organic nitrogen content. The specific Ex/Em peak related to protein-like substances gradually disappeared, while those related to humic acid-like substances continued to increase thereafter. Fluorescence regional integration (FRI) results showed an ascended PV,n/PIII,n index (1.94) and significant correlations with chemical data (M2=0.2875, r=0.8441, P<0.001, 999 permutations for Procrustes analysis). Taken together, despite the temporal changes in chemical and fluorescent data after soil conditioning, the increased content of SOM containing humic acid-like substances was observed at the end of the incubation period compared with control soil samples, indicating that the microwave-pretreated CMD might be applied as a soil amendment. PMID- 29190567 TI - Simulating emissions of 1,3-dichloropropene after soil fumigation under field conditions. AB - Soil fumigation is an important agricultural practice used to produce many vegetable and fruit crops. However, fumigating soil can lead to atmospheric emissions which can increase risks to human and environmental health. A complete understanding of the transport, fate, and emissions of fumigants as impacted by soil and environmental processes is needed to mitigate atmospheric emissions. Five large-scale field experiments were conducted to measure emission rates for 1,3-dichloropropene (1,3-D), a soil fumigant commonly used in California. Numerical simulations of these experiments were conducted in predictive mode (i.e., no calibration) to determine if simulation could be used as a substitute for field experimentation to obtain information needed by regulators. The results show that the magnitude of the volatilization rate and the total emissions could be adequately predicted for these experiments, with the exception of a scenario where the field was periodically irrigated after fumigation. In addition, the timing of the daily peak 1,3-D emissions was not accurately predicted for these experiments due to the peak emission rates occurring during the night or early morning hours. This study revealed that more comprehensive mathematical models (or adjustments to existing models) are needed to fully describe emissions of soil fumigants from field soils under typical agronomic conditions. PMID- 29190570 TI - Grooving of nanoparticles using sublimable liquid crystal for transparent omniphobic surface. AB - Hierarchical assembly of nanoparticles (NPs) is of interest for omniphobic surfaces in the way that hierarchical scale roughness possibly provides effective liquid repellency and also it is relatively easy to build large-area coatings via the bottom-up assembly process. However, all NP assemblies often lacks mechanical robustness. Hence, the development of the effective fabrication method to make well-deposited hierarchical NPs assembly is demanded. In this report, we have demonstrated an all-NP three-dimensional hierarchical surface that is omniphobic yet highly transparent and mechanically robust. By taking advantage of sublimation and recondensation of smectic A liquid crystals (LCs) in a simple thermal annealing process, we patterned NP aggregates in one-dimensional grooves directed by LCs. The resultant groove-like NP-assembled surface showed omniphobicity, repelling water, glycerol, ethylene glycol, and olive oil (with contact angle of 156.5 degrees , 147 degrees , 136.5 degrees , and 123.2 degrees , respectively) because of the low surface energy of the fluorinated NPs and dual roughness. The coating is highly transparent with ~90% transmittance in the visible wavelength. We investigate the mechanical robustness of the all NP coatings by sand abrasion, which shows nearly identical omniphobicity and transparency after the sand abrasion. PMID- 29190565 TI - Contrasting responses of soil respiration and temperature sensitivity to land use types: Cropland vs. apple orchard on the Chinese Loess Plateau. AB - Land use plays an essential role in regional carbon cycling, potentially influencing the exchange rates of CO2 flux between soil and the atmosphere in terrestrial ecosystems. Temperature sensitivity of soil respiration (Q10), as an efficient parameter to reflect the possible feedback between the global carbon cycle and climate change, has been extensively studied. However, very few reports have assessed the difference in temperature sensitivity of soil respiration under different land use types. In this study, a three-year field experiment was conducted in cropland (winter wheat, Triticum aestivum L.) and apple orchard (Malus domestica Borkh) on the semi-arid Loess Plateau from 2011 to 2013. Soil respiration (measured using Li-Cor 8100), bacterial community structure (represented by 16S rRNA), soil enzyme activities, and soil physicochemical properties of surface soil were monitored. The average annual soil respiration rate in the apple orchard was 12% greater than that in the cropland (2.01 vs. 1.80MUmolm-2s-1), despite that the average Q10 values in the apple orchard was 15% lower than that in the cropland (ranging from 1.63 to 1.41). As to the differences among predominant phyla, Proteobacteria was 26% higher in the apple orchard than that in the cropland, whereas Actinobacteria and Acidobacteria were 18% and 36% lower in the apple orchard. The beta-glucosidase and cellobiohydrolase activity were 15% (44.92 vs. 39.09nmolh-1g-1) and 22% greater (21.39 vs. 17.50nmolh-1g-1) in the apple orchard than that in the cropland. Compared to the cropland, the lower Q10 values in the apple orchard resulted from the variations of bacterial community structure and beta-glucosidase and cellobiohydrolase activity. In addition, the lower C: N ratios in the apple orchard (6.50 vs. 8.40) possibly also contributed to its lower Q10 values. Our findings call for further studies to include the varying effects of land use types into consideration when applying Q10 values to predict the potential CO2 efflux feedbacks between terrestrial ecosystems and future climate scenarios. PMID- 29190566 TI - Life cycle and hydrologic modeling of rainwater harvesting in urban neighborhoods: Implications of urban form and water demand patterns in the US and Spain. AB - Water management plays a major role in any city, but applying alternative strategies might be more or less feasible depending on the urban form and water demand. This paper aims to compare the environmental performance of implementing rainwater harvesting (RWH) systems in American and European cities. To do so, two neighborhoods with a water-stressed Mediterranean climate were selected in contrasting cities, i.e., Calafell (Catalonia, Spain) and Ukiah (California, US). Calafell is a high-density, tourist city, whereas Ukiah is a typical sprawled area. We studied the life cycle impacts of RWH in urban contexts by using runoff modeling before (i.e. business as usual) and after the implementation of this system. In general, cisterns were able to supply >75% of the rainwater demand for laundry and toilet flushing. The exception were multi-story buildings with roofs smaller than 200m2, where the catchment area was insufficient to meet demand. The implementation of RWH was environmentally beneficial with respect to the business as-usual scenario, especially because of reduced runoff treatment needs. Along with soil features, roof area and water demand were major parameters that affected this reduction. RWH systems are more attractive in Calafell, which had 60% lower impacts than in Ukiah. Therefore, high-density areas can potentially benefit more from RWH than sprawled cities. PMID- 29190571 TI - Patterns and predictors of pain following lung transplantation. AB - OBJECTIVE: Our objective was to examine variability in pain levels following lung transplantation, and examine individual biopsychosocial factors influencing changes in pain. METHOD: We performed a retrospective study of a cohort of 150 patients transplanted and discharged from Duke University Hospital between January 2015 and September 2016. During hospitalization and at clinic visits up to two months after discharge, subjective pain ratings were obtained using a 0-10 Numeric Rating Scale. Psychiatric diagnoses of anxiety and depression and Center for Epidemiological Studies - Depression (CES-D) scores collected after hospital discharge were examined as predictors of post-surgery pain. Medical and surgical variables were examined as covariates. RESULTS: During hospitalization, pain ratings decreased over time (p<0.001). Predictors of higher pain levels included pre-transplant history of depression (p=0.001) and anxiety (p=0.04), bilateral lung transplant (p=0.03), and lower six-minute walk distance (p=0.02). Two months after discharge, 18% of patients reported continued pain and 34% remained on opioid pain medications. Two months after discharge, more frequent post-operative complications predicted higher pain levels in a univariate analysis (p=0.02) although this relationship was attenuated after adjustment for depression. In a multivariate analysis, elevated CES-D scores (p=0.002), and greater opioid use (p=0.031) predicted higher pain levels 2-months post-discharge. CONCLUSION: We conclude that patients with psychiatric comorbidities may be at risk for greater pain, and may require additional strategies for more effective pain management. PMID- 29190569 TI - The effect of the relative permittivity on the tactoid formation in nanoplatelet systems. A combined computer simulation, SAXS, and osmotic pressure study. AB - The structural properties, and the intracrystalline swelling of Na+-, and Ca2+ montmorillonite (Na-, and Ca-mmt) have been investigated as an effect of decreasing the relative permittivity of the solvent, i.e. from water to ethanol (EtOH), utilizing the experimental techniques; small angle X-ray scattering (SAXS) and osmotic pressure measurements. The experimental data were compared with the continuum model, utilizing coarse-grained molecular dynamics bulk simulations, Monte Carlo simulations of two infinite parallel surfaces corresponding to two clay platelets, and the strong coupling theory. It was found that it is possible to tune the electrostatic interactions to obtain a transition from a repulsive to an attractive system for the Na-mmt by increasing the EtOH concentration, i.e. the Bjerrum length increases, and hence, the attractive ion ion correlation forces are enhanced. A qualitative agreement was observed between the simulations and the experimental results. Moreover, a non-monotonic behavior of the intracrystalline swelling of Ca-mmt as a function of EtOH concentration was captured experimentally, where an increase in the osmotic pressure, and hence, an increase in the d-spacing was found at low concentrations, indicating that repulsive short-ranged interactions dominate in the system. Theoretically, the non-monotonic behavior could not be captured with the continuum model, probably due to the limitation that the electrostatic interactions solely enters the Hamiltonian via the Bjerrum length. PMID- 29190568 TI - Polydopamine-assisted immobilization of hierarchical zinc oxide nanostructures on electrospun nanofibrous membrane for photocatalysis and antimicrobial activity. AB - Depositing of hierarchical ZnO nanostructures on electrospun nanofibers and their proper attachment has gained significant interest for myriad applications. However, the weak attachment of such nanostructures to the nanofiber surface limits their practical applications. In this study, a simple and efficient method has been developed for preparing hierarchical ZnO nanorod deposited polyurethane (PU) nanofiber by combining electrospinning, surface functionalization and hydrothermal treatment. Electrospun PU nanofibers were coated with polydopamine (Pdopa) via dip coating method. The resulting Pdopa coated PU nanofibrous mat was soaked in aqueous ZnO nanoparticles (ZnONPs) solution in order to seed the metal oxide particles on its surface. Later, ZnO nanorods (ZNRs) were grown on the ZnO seeded electrospun PU nanofiber via a hydrothermal process. X-ray photoelectron spectroscopy (XPS), Field-Emission Scanning electron microscopy (FE-SEM), X-ray diffraction pattern (XRD) and infra-red (IR) spectra indicated that ZnO nanorods firmly adhered to the functionalized PU nanofiber surface and had high photocatalytic/antimicrobial activity at the low-intensity UV-LED device with good reusability. The catechol group of Pdopa not only causes adhesion of ZnO nanostructures, but also act as an electron trap, preventing the recombination of e-h pairs and thereby improving the photocatalytic efficiency. We believe that the fabricated composite membrane with antifouling effect and photocatalytic activity is a potential candidate for organic pollutant degdration and wastewater purification. PMID- 29190572 TI - Increased prevalence and risk of anxiety disorders in adults with tinnitus: A population-based study in Taiwan. AB - OBJECTIVE: Tinnitus is a common disorder that may cause psychological distress and anxiety. The aim of this study was to investigate the association between anxiety disorders (ADs) and tinnitus in a large population. METHOD: We conducted a cross-sectional study using the National Health Insurance Research Database in Taiwan. Study subjects included 14,772 patients with tinnitus and 709,963 people in the general population who sought treatment in 2005. Distributions in ADs, age, sex, and medical comorbidities were compared between groups using chi squared tests. Multivariate logistic regression models adjusted for age, sex, and medical comorbidities were used to analyze the association between tinnitus and ADs. RESULTS: Prevalence of ADs in tinnitus and general population groups was 3.9% and 1.5%, respectively, and this difference was significant (P<0.001). Diabetes mellitus, hypertension, hyperlipidemia, concussion or head injury, Meniere's disease, sensorineural hearing impairment, renal disease, coronary artery disease, and cerebrovascular disease were significantly more prevalent in the tinnitus group (all P-values<0.001). Multivariate logistic regression model demonstrated that patients with tinnitus were significantly associated with increased risk of ADs (adjusted OR=1.99; 95% CI=1.81-2.19; P<0.001). CONCLUSION: Because the risk of ADs was significantly higher in patients with tinnitus than in the general population, physicians should be aware of the importance of psychological factors in tinnitus management.

AB - The authors report a case of a 69-year-old woman with multiple sclerosis treated with fingolimod for duration of over one year who subsequently developed cutaneous large B cell lymphoma. There are few reported cases of lymphoma associated with fingolimod treatment for multiple sclerosis, but rates are higher than expected in the general population. The authors hope to promote awareness of the potential risk of this medication so that more diligent disease surveillance can be performed by both prescribing practitioners of fingolimod and their patients who receive it. PMID- 29190576 TI - The semiotics of medical image Segmentation. AB - As the interaction between clinicians and computational processes increases in complexity, more nuanced mechanisms are required to describe how their communication is mediated. Medical image segmentation in particular affords a large number of distinct loci for interaction which can act on a deep, knowledge driven level which complicates the naive interpretation of the computer as a symbol processing machine. Using the perspective of the computer as dialogue partner, we can motivate the semiotic understanding of medical image segmentation. Taking advantage of Peircean semiotic traditions and new philosophical inquiry into the structure and quality of metaphors, we can construct a unified framework for the interpretation of medical image segmentation as a sign exchange in which each sign acts as an interface metaphor. This allows for a notion of finite semiosis, described through a schematic medium, that can rigorously describe how clinicians and computers interpret the signs mediating their interaction. Altogether, this framework provides a unified approach to the understanding and development of medical image segmentation interfaces. PMID- 29190579 TI - Efficacy and safety of vigabatrin in Japanese patients with infantile spasms: Primary short-term study and extension study. AB - Vigabatrin was approved for the treatment of infantile spasms by the US Food and Drug Administration, but not in Japan at the time of initiating this clinical study because of concerns about irreversible peripheral visual field defects (VFDs). This study evaluated the efficacy and safety of vigabatrin for Japanese patients with infantile spasms. Of 15 patients (aged >=4weeks and <2years) enrolled, with the exception of two patients who did not receive vigabatrin, 13 were treated with a titrated dosage of vigabatrin (50-150mg/kg/day; limited to 3000mg/day). Twelve out of 13 patients receiving vigabatrin had spasms that were treatment refractory; these patients were concurrently treated with at least one other antiepileptic drug. One patient received vigabatrin monotherapy. Eight of the 13 patients (61.5% [95% CI: 31.6-86.1%]) had a >=50% reduction during the dose-adjustment phase compared with baseline in the frequency of spasms, with efficacy maintained through a 2-week maintenance phase. Spasms disappeared in six out of nine patients (66.7% [95% CI: 29.9-92.5%]) who transitioned to the maintenance phase and hypsarrhythmia on electroencephalography also resolved in four patients. Hypsarrhythmia was improved in another two patients. Six out of seven patients who continued treatment through Week 32 of an extension study reported ongoing efficacy for vigabatrin. The most common adverse events (AEs) were psychiatric disorders and nervous system disorders (n=8; 61.5%) that were generally mild in severity. No treatment-related peripheral VFDs were observed. No severe AEs or AEs resulting in discontinuation of vigabatrin therapy were reported. An abnormality in magnetic resonance images was observed in one patient during the extension period. Vigabatrin was deemed to be clinically effective and well tolerated in Japanese patients with infantile spasms. PMID- 29190573 TI - Common comorbidities and survival in MS: Risk for stroke, type 1 diabetes and infections. AB - BACKGROUND: Survival in MS has increased during the era of disease modifying therapies, but life expectancy in MS patients is still reduced by several years. Increased risk for common comorbidities related to brain health, such as risk for circulatory diseases have been reported in MS and could affect survival. In this paper, we studied age- and gender adjusted risks for circulatory diseases and related disorders, and their impact on overall MS survival in population of Southwest Finland. MATERIALS AND METHODS: The ICD-10 codes for hospital visits were searched from the administrative data pool from 1.1.2004 up to 31.12.2012 for the resident MS and control cases at the Hospital District of Southwest Finland. The MS population under study consisted of prevalent cases in 1.1.2004 and new cases from 1.1.2004 followed up to death or 31.12.2012. Patient documents were scrutinized to confirm the MS diagnosis (G 35) by the McDonald's criteria and to confirm the diagnoses and causes of death for the cerebro- and cardiovascular diagnoses under study. The randomly chosen 10-fold control population was matched by birth year and gender to calculate the coincident risks (odds ratio, OR) with 95% confidence intervals (95% CI) and another separate control population from the same patient pool was used to verify the stability of the results. P-values were calculated using Pearson's chi2 test. The Kaplan- Meier analysis log rank test was applied to study survival. RESULTS: During the follow-up 1074 confirmed MS cases were treated in the hospital district, including the deceased cases after 1.1.2004 (5.9%). The probability of survival was 82.4 years among MS and 85.6 years among the control cases, log rank p < 0.001. The survival disadvantage within MS was associated with comorbidity for circulatory disease codes in ICD -10: I06-I71, log rank p < 0.001. The specific risk for ischemic and haemorrhagic stroke was significant with high OR of 1.49 (95% CI 1.03- 2.35) and 2.5 (1.24-5.06) respectively. The two-fold risk for type 1 diabetes in MS was significant, OR 2.1 (1.3-3.36). The main causes of death among the MS cases were infections and the coincident high risk for several infections was significant. There was no difference in the risk for acute myocardial infarct, transient ischemic attack, atrial fibrillation, hypertension, or obesity in comparison with the control cases. CONCLUSIONS: Given the high risk for stroke in this MS population and the observed complexity among the coincident common risk factors for circulatory diseases, the high risk for type 1 diabetes and common infections raise a need to recognize patients at risk with these conditions and with the other known risk factors such as metabolic syndrome and smoking. The survival disadvantage related to circulatory diseases observed in general population is true also in MS and should be recognized to reduce the burden of disease and premature mortality in MS.

AB - Diffusion magnetic resonance imaging (dMRI) has enabled in vivo investigation of white matter tracts. Fiber orientation (FO) estimation is a key step in tract reconstruction and has been a popular research topic in dMRI analysis. In particular, the sparsity assumption has been used in conjunction with a dictionary-based framework to achieve reliable FO estimation with a reduced number of gradient directions. Because image noise can have a deleterious effect on the accuracy of FO estimation, previous works have incorporated spatial consistency of FOs in the dictionary-based framework to improve the estimation. However, because FOs are only indirectly determined from the mixture fractions of dictionary atoms and not modeled as variables in the objective function, these methods do not incorporate FO smoothness directly, and their ability to produce smooth FOs could be limited. In this work, we propose an improvement to Fiber Orientation Reconstruction using Neighborhood Information (FORNI), which we call FORNI+; this method estimates FOs in a dictionary-based framework where FO smoothness is better enforced than in FORNI alone. We describe an objective function that explicitly models the actual FOs and the mixture fractions of dictionary atoms. Specifically, it consists of data fidelity between the observed signals and the signals represented by the dictionary, pairwise FO dissimilarity that encourages FO smoothness, and weighted l1-norm terms that ensure the consistency between the actual FOs and the FO configuration suggested by the dictionary representation. The FOs and mixture fractions are then jointly estimated by minimizing the objective function using an iterative alternating optimization strategy. FORNI+ was evaluated on a simulation phantom, a physical phantom, and real brain dMRI data. In particular, in the real brain dMRI experiment, we have qualitatively and quantitatively evaluated the reproducibility of the proposed method. Results demonstrate that FORNI+ produces FOs with better quality compared with competing methods. PMID- 29190577 TI - CTAB and SDS assisted facile fabrication of SnO2 nanoparticles for effective degradation of carbamazepine from aqueous phase: A systematic and comparative study of their degradation performance. AB - In the present study, SnO2 nanoparticles were successfully synthesized by chemical precipitation method using anhydrous aspartic acid and surfactant at two annealing temperatures, 300 degrees C and 600 degrees C. The effect of surfactants cationic CTAB and anionic SDS on the synthesized SnO2 nanoparticles (NPs) were studied elaborately. In this article, for the first time, SnO2 NPs were employed as an excellent photocatalyst in the degradation of carbamazepine (CBZ), a popular antiepileptic drug which is most commonly detected pharmaceutically active compounds (PhACs) in municipal wastewater under UV-C light irradiation. Comparative studies between the photocatalytic activity of SnO2 NPs synthesized with CTAB (SC1) and SDS (SS1) on the degradation of the CBZ drug were investigated. Parameters like the effect of catalytic loading, initial concentration, pH and contact time were also studied for optimization. The results indicate that SC1 is a better photocatalyst with rate constant 6.66 * 10 2 min-1 than SS1 with rate 5.7 * 10-2 min-1. To determine the transformation product formed on the photodegradation LCMS (ESI) analysis was done. The synthesized SnO2 NPs can be recycled up to 8th cycles without any notable alteration in its photocatalytic activity.

AB - To achieve superior fire safety epoxy resins (EP), a novel multifunctional organic-inorganic hybrid, melamine-containing polyphosphazene wrapped ammonium polyphosphate (PZMA@APP) with rich amino groups was prepared and used as an efficient flame retardant. Thanks to the cross-linked polyphosphazene part, PZMA@APP exhibited high flame retardant efficiency and smoke suppression to the EP composites. Thermogravimetric analysis indicated that PZMA@APP significantly enhanced the thermal stability of EP composites. The obtained sample passed UL-94 V-0 rating with 10.0wt% addition of PZMA@APP. Notably, inclusion of incorporating PZMA@APP leads to significantly decrease on fire hazards of EP, for instance, bring about a 75.6% maximum decrease in peak heat release rate and 65.9% maximum reduction in total heat release, accompanied with lower smoke production rate and higher graphitized char layer. With regards to mechanical property, the glass transition temperature of EP/PZMA@APP10.0 was as high as 184.5 degrees C. In particular, the addition of PZMA@APP did not worsen the mechanical properties, compared to pure APP. It was confirmed that the participation of melamine containing polyphosphazene could significantly enhance the quality of char layer and thereby resulting the higher flame retardant efficiency of PZMA@APP.

AB - Superhydrophobic and superoleophilic porous reduced graphene oxide/polycarbonate (RGO/PC) monoliths with novel micro-nanoscale binary structure were first fabricated by thermally impacted nonsolvent induced phase separation (TINIPS) method. Owing to the unique pore structure, the porous monoliths possessed high specific surface area (137.19m2/g) and porosity (91.3%). The superhydrophobic RGO/PC monoliths exhibited excellent capability to selectively adsorb a wide range of oils and organic solvents from water. Furthermore, the monoliths could keep a stable repellency against corrosive mediums (e.g., acidic and alkali solutions). Based on these superior properties, porous RGO/PC monoliths will be a promising candidate for high-efficiency oil/water separation to deal with water pollution. PMID- 29190578 TI - Evaluation of a full-scale wastewater treatment plant upgraded with ozonation and biological post-treatments: Abatement of micropollutants, formation of transformation products and oxidation by-products. AB - To protect the ecosystem and drinking water resources in Switzerland and in the countries of the downstream catchments, a new Swiss water protection act entered into force in 2016 aiming to reduce the discharge of micropollutants from wastewater treatment plants (WWTPs). As a consequence, selected WWTPs must be upgraded by an advanced treatment for micropollutant abatement with suitable and economic options such as (powdered) activated carbon treatment or ozonation. WWTP Neugut (105'000 people equivalent) was the first WWTP in Switzerland to implement a long-term full-scale ozonation. Differing specific ozone doses in the range of 0.35-0.97 g O3/g DOC were applied to determine the adequate ozone dose to fulfill the requirements of the Swiss water protection act. Based on this assessment, a specific ozone dose of 0.55 g O3/g DOC is recommended at this plant to ensure an average abatement of the twelve selected indicator substances by >=80% over the whole treatment. A monitoring of 550 substances confirmed that this dose was very efficient to abate a broad range of micropollutants by >79% on average. After ozonation, an additional biological post-treatment is required to eliminate possible negative ecotoxicological effects generated during ozonation caused by biodegradable ozonation transformation products (OTPs) and oxidation by-products (OBPs). Three biological treatments (sand filtration, moving bed, fixed bed) and granular activated carbon (GAC, fresh and pre-loaded) filtration were evaluated as post-treatments after ozonation. In parallel, a fresh GAC filter directly connected to the effluent of the secondary clarifier was assessed. Among the three purely biological post-treatments, the sand filtration performed best in terms of removal of dissolved organic carbon (DOC), assimilable organic carbon (AOC) and total suspended solids (TSS). The fresh activated carbon filtration ensured a significant additional micropollutants abatement after ozonation due to sorption. The relative abatement of the indicator substances ranged between 20 and 89% after 27'000 bed volumes (BV) and was still substantial at 50'000 BV. In an identical GAC filter running in parallel and being fed with the effluent of the secondary clarifier, the elimination was less efficient. Seven primary OTPs (chlorothiazide and six N-oxides) formed during ozonation could be quantified thanks to available reference standards. Their concentration decreased with increasing specific ozone doses with the concomitant formation of other OTPs. The seven OTPs were found to be stable compounds and were not abated in the biological post-treatments. They were sorbed in the fresh GAC filter, but less efficiently than the corresponding parent compounds. Two OBPs, bromate (BrO3-) and N-nitrosodimethylamine (NDMA), were formed during ozonation but did not exceeded 5 MUg/L for bromate and 30 ng/L for NDMA at the recommended specific ozone dose of 0.55 g O3/g DOC. NDMA was well abated in all post-treatments (minimum 41% during fixed bed filtration, maximum 83% during fresh GAC filtration), while bromate was very stable as expected.

AB - We developed nanoporous adsorbent exhibiting unprecedented performance in separation of toxic carbon monoxide (CO). The adsorbent was prepared by dispersing CuCl on mesoporous boehmite via thermal monolayer dispersion route. A key point of the present synthesis is dispersing optimized amount of CuCl on the boehmite at a moderate temperature to maintain the characteristics of the boehmite. We performed a systematic study to reveal that a CuCl/boehmite composite (30wt% CuCl in total) thermally treated at 573K was the best optimized sample for CO separation. The CuCl/boehmite had a high capacity of CO adsorption (1.56mmolg-1) and an exceedingly low capacity of CO2 adsorption (0.13mmolg-1) under 100kPa of each gas at 293K. The CO/CO2 separation factor was 12.4. To the best of our knowledge, this value is the best on record. The achievement of this work is attributed to finding a new type of suitable supporting material: boehmite. The boehmite has a high affinity to CuCl, exhibits excellent dispersion of the CuCl, and achieves a superior CO adsorption capacity. However, it has a weak interaction with CO2. The CuCl/boehmite composite is a promising adsorbent for selective separation of CO from combustion exhaust and industrial off-gas streams.

AB - Environmental risk assessment procedures require acute and chronic toxicity values of hazardous chemicals. In this respect, the 96-h toxicity bioassays of nitro-, methyl-, methoxy-, chloro-, and nitrile- substituted phenols and anilines to Chlorella vulgaris were performed. Median inhibitory and low-toxic-effect concentrations were reported. Significant correlations between acute and chronic toxicities were found for the chemicals in the data set regardless of mode of action. Consequently, linear models employing theoretical and empirical descriptors were developed for the prediction of NOEC and IC20. The outcome of the study will be beneficial in the risk assessments of organic chemicals and setting water quality standards by the regulators. PMID- 29190580 TI - Potentially antidiabetic and antihypertensive compounds identified from Pistacia atlantica leaf extracts by LC fingerprinting. AB - The objective of this paper is to evaluate the variations in the ability of Pistacia atlantica leaves to inhibit enzymes linked to type 2 diabetes (alpha amylase and alpha-glucosidase) and to hypertension (angiotensin converting enzyme I (ACE-I)), depending on harvesting month, gender and growing region, as well as to identify the peaks in chromatographic fingerprints that potentially correspond to components with enzymatic inhibitory activities. In this study, LC fingerprints of P. atlantica leave extracts were developed. Peaks which were probably responsible for the anti-amylase, anti-glucosidase and anti-ACE-I activities were assigned. For the latter purpose, the relevant information was extracted, linking the chromatographic fingerprints with the activities using a linear multivariate calibration technique, i.e., Partial Least Squares (PLS) regression. Prior to the construction of the models, the fingerprints are aligned using a warping method, called Correlation Optimized Warping (COW). Besides COW, different other data pretreatment methods were applied and compared. Our findings revealed that the influence of the growing region and gender on the alpha amylase, alpha-glucosidase and ACE-I inhibitory activities of P. atlantica leaves was less important than the harvest time. Thirteen common peaks were selected from the chromatograms and used as a dataset to model the biological activities. The peaks potentially responsible for the biological activity of the samples were indicated by studying the regression coefficients of the models. Seven peaks corresponding to possibly anti-amylase compounds were found, while 6 peaks were considered important for inhibiting the alpha-glucosidase activity. Furthermore, the regression coefficients of the hypertension model indicated eight peaks as being important for inhibiting the ACE-I activity. The contributions of individual phenolic compounds of P. atlantica leaves to the alpha-amylase, alpha glucosidase and ACE-I inhibitory activities were also identified. This investigation showed that the extract of P. atlantica leaves provides a rational basis for the isolation and development of antidiabetic and antihypertensive agents.

AB - The RuO2-Ag3PO4 heterostructured nanocomposite was successfully synthesized by facile in situ deposition of porous ruthenium oxide (RuO2) nanoparticles on the surface of the silver phosphate (Ag3PO4). Under visible light irradiation, the 0.5wt.% RuO2-Ag3PO4 heterostructure photocatalyst exhibits enhanced photocatalytic efficiency compared to other composites of RuO2-Ag3PO4 and Ag3PO4. The optimized 0.5wt.% RuO2-Ag3PO4 nanocomposites exhibited 1.5 times enhanced photocatalytic activity towards the degradation of methylene blue (MB) than Ag3PO4. Moreover, the degradation rate of 0.5wt.% RuO2-Ag3PO4 nanocomposite towards the cationic dyes MB and rhodamine B (RhB) was nearly 6.6 times and 4.7 times higher than that towards the anionic dye methyl orange (MO). The formed heterojunction electric field of 310mV at the interface between RuO2 and Ag3PO4 heterostructure induces downward band bending of Ag3PO4. Also, this electric field increases the separation efficiency of electrons-holes resulting higher degradation efficiency. The quenching effect of scavengers test confirms that holes are reactive species and the RuO2-Ag3PO4 nanocomposite is highly stable, exhibited 88% of MB degradation after 4 recycles. The RuO2-Ag3PO4 nanocomposites inhibit self oxidation of Ag3PO4 resulting improved efficiency and stability. PMID- 29190585 TI - A novel "turn-on" fluorescent probe based on triphenylimidazole-hemicyanine dyad for colorimetric detection of CN- in 100% aqueous solution. AB - A new colorimetric fluorescent probe (MCy) for CN- is designed and synthesized based on triphenylimidazole-hemicyanine dyad. The probe shows high selectivity towards CN- in 100% aqueous solution even in the presence of other competitive anions such as F-, Cl-, AcO-, NO2-, H2PO4-, I-, SCN-, SO42-, NO3-, HCO3-, Br- and S2-. Upon nucleophilic addition of CN- to the indolium group, the probe displays large blue-shift in UV-vis spectrum and remarkable "turn-on" fluorescence owing to the disruption of intramolecular charge transfer. Meanwhile, the probe also undergoes a naked-eye discernible color change from orange to light pink in the sunlight as well as an obvious fluorescence color change from non-emissive to bright blue under a UV lamp. The detection limit of CN- in aqueous solution can be as low as 20.6nM, which is much lower than the permissible level of CN- in drinking water according to the WHO. In addition, the probe has been successfully used to determine CN- in real water samples as well as to fabricate test paper kit for CN- detection. PMID- 29190586 TI - Efficiency of the formulated plant-growth promoting Pseudomonas fluorescens MC46 inoculant on triclocarban treatment in soil and its effect on Vigna radiata growth and soil enzyme activities. AB - For bioaugmentation-based treatment of triclocarban (TCC), an emerging soil pollutant that is recalcitrant to biodegradation and phytotransformation, efficient TCC-degrading bacteria with an effective soil-delivering means are required. This work developed the formulated bacterial inoculant, and successfully demonstrated its TCC removal and detoxification performance in pot soil experiment with Vigna radiata plants. The soil bacterium Pseudomonas fluorescens MC46 was isolated as TCC-degrading, plant-growth promoting bacterium. The characterizations were conducted in vitro revealing that it could utilize TCC as a sole carbon source, and at a wide and higher concentration range from 1.6 31.6mgkg-1 than those previously reported, while the detoxification was assessed by cytogenotoxicity and phytotoxicity tests. The developed sawdust-based inoculant formula combined with molasses (5% w/w), and either PEG or CMC-starch blend (1% w/w) could maintain a 20-week shelf-life inoculant stability in terms of cell viability, and TCC-degrading activity. Bioaugmentation of the formulated inoculants into TCC-contaminated soil efficiently removed TCC up to 74-76% of the initial concentration, mitigated toxicity, restored plant growth and health, and enhanced soil enzyme activities. This work is the first to demonstrate potential application of the formulated plant-growth promoting bacterial inoculant for the treatment and detoxification of a persistent TCC contaminated in soil. PMID- 29190590 TI - The impact of simulation based education on nursing confidence, knowledge and patient outcomes on general medicine units. AB - The ability to quickly and reliably detect a clinically deteriorating patient and intervene appropriately is a skill nurses are expected to bring into practice. Simulation education has been shown to improve nurses' knowledge, confidence and communication, especially when focused on deteriorating patients. In a simulation center at a large tertiary level Canadian teaching hospital, a 4 h simulation based education session was developed for general medicine nursing staff. The education included a didactic lecture followed by four 40 min simulation scenarios focused on deteriorating patient. This study was designed as a pre- and post-analytic design. It utilized a paper based survey completed at three separate time points to measure confidence and knowledge. The study also examined data from the Critical Care Outreach nurse audits and site code blue audit data. Results demonstrated statistically significant improvements in nursing confidence and knowledge, and were sustained over the three month follow-up period. PMID- 29190588 TI - LRFN (leucine-rich repeat and fibronectin type-III domain-containing protein) recognizes bacteria and promotes hemocytic phagocytosis in the Pacific oyster Crassostrea gigas. AB - In bivalve mollusks, circulating hemocyte mediated phagocytosis is one of the primary ways to eliminate invading microbes. Here, we have identified one CgLRFN (leucine-rich repeat and fibronectin type-III domain-containing protein) in the Crassostrea gigas as a novel transmembrane LRR (Leucine-rich repeat) domain containing protein in C. gigas, homologous to the jawless fish VLR protein, that plays an important role in recognizing bacteria and promoting hemocytic phagocytosis. Tissue distribution analysis of CgLRFN in Pacific oyster showed that it is widely expressed in various tissues like the gills, adductor muscles, digestive glands, gonads, heart and in the hemocytes. Furthermore, infection of Pacific oysters with two marine Vibrio strains V. alginolyticus and V. parahaemolyticus was found to significantly increase CgLRFN expression in the hemocytes. Analysis of subcellular localization showed that CgLRFN is primarily localized in the cell membrane. Additionally, CgLRFN was found to be able to bind both the bacterial strains, indicating its possible role as a cell surface receptor. Flow cytometry analysis revealed that CgLRFN coated bacteria was phagocytosed by oyster hemocytes at a significantly higher rate compared to the uncoated bacteria. Finally, RNAi mediated knockdown of CgLRFN in vivo resulted in reduced clearance of both the bacterial strains from the oyster hemolymph. Overall, our study demonstrates that CgLRFN acts as a pattern recognition receptor for Vibrio spp. and promotes hemocytic phagocytosis in the Pacific oyster, which is critical for understanding the mechanism of bacterial infection in lower invertebrates, and also contributes to disease management of this economically and ecologically important marine mollusk. PMID- 29190592 TI - Performance of direct anaerobic digestion of dewatered sludge in long-term operation. AB - Direct anaerobic digestion of dewatered sludge with total solids (TS) content of 15-20% was tested in a horizontal digester for one and half years. The system kept stable with pH 7-8. The concentration of volatile fatty acids was lower than 800 mg/L, free ammonia nitrogen was lower than 200 mg/L, and total alkalinity kept higher than 6000 mg/L. The performance was influenced by organic load rate (OLR) and organic content in feed sludge. When volatile solids (VS) in TS of feed sludge reached 60-65% at OLR 3.50-3.70 g/(L.d), the process exhibited the best performance with organic removal rate of 32.19 +/- 7.73% and methane production of 156.86 +/- 13.05 ml/g VS added. Microbial analyses indicated that Methanosarcina became predominant and Methanosaeta almost disappeared. Moreover, hydrogenotrophic and methylotrophic methanogens accounted for 18.13-29.40% and 11.58-29.56% of the total, respectively. These provide a new guideline for small scale or centralized sludge treatment. PMID- 29190591 TI - First report of a fish kill episode caused by pyrethroids in Italian freshwater. AB - INTRODUCTION: Fish kills are events of strong emotional impact on the population because of the frequent suspicion that they can be the result of serious pollution accidents. As a matter of fact, they are often due to natural occurrences, such as low levels of dissolved oxygen in the water, but in many cases the causes remain unknown. Fish are particularly sensitive to pesticides and pyrethroids are reported to be the most ecotoxicologically active in the aquatic environment. Nevertheless, the reported cases of massive wild fish mortalities due to these toxicants are very few. This paper describes a fish kill episode occurred in the Padua Province (Veneto Region - North Eastern Italy) which involved several fish species and for which it was possible to identify the cause in the presence of pyrethroids in the water. CASE PRESENTATION: When a whitish liquid coming from the rainwater drain of an industrial area was seen to be spilling into a drainage channel, a fish massive mortality was noticed and investigated. The collected water samples showed the presence of relevant concentrations of cypermethrin, permethrin, deltamethrin and tetramethrin. Analyses on the fish tissues revealed the presence of cypermethrin and permethrin at a concentration range of 476-2834MUg/kg and 346-2826MUg/kg on a lipid basis, respectively. DISCUSSION: According to the results of the performed analyses, we can reasonably state that the described episode had been caused by the exposure of biota to high concentrations of pyrethroids. The present case report significantly contributes to the limited literature available on pesticides related fish kills. Moreover, it highlights the importance of sharing protocols for fish kill management at a national level, as this would help to better define the roles of the different institutions involved and to improve the investigation and the reporting of these events. PMID- 29190589 TI - Professional formation through personal involvement and value integration. AB - Formation is an important part of nursing education, and it is the responsibility of nurse educators to facilitate learning situations that provide students with opportunities for personal discovery. Studies have shown that awareness of one's own vulnerability can be a source of professional maturation and courageous action. The study setting is a Christian university that emphasises its value base through the perspective of diakonia in the nursing programme. Diakonia is understood as the provision of caring. Two hundred and forty-five pages of reflective journals from 124 third-year students were analysed with qualitative content analysis. The main theme of the study was Professional formation through personal involvement and value integration. Four categories emerged: 1) Diakonia as a guide to professional compassion; 2) Consciousness of one's own values; 3) The urge to act courageously; and 4) Choosing to spend the time available. The article discusses how students can integrate values in their professional lives by using all senses when learning in real-life situations and by using systematic reflection alone and together with others. Professional formation is an ongoing process, and we have found that mandatory participation, reiteration and progression are important conditions for such formation to occur.

AB - A novel bio-refinery sequence yielding varieties of co-products was developed using straw pulping solid residue. This process utilizes neutral sulfite pretreatment which under optimal conditions (160 degrees C and 3% (w/v) sulfite charge) provides 64.3% delignification while retaining 90% of cellulose and 67.3% of xylan. The pretreated solids exhibited excellent enzymatic digestibility, with saccharification yields of 86.9% and 81.1% for cellulose and xylan, respectively. After pretreatment, the process of semi-simultaneous saccharification and fermentation (S-SSF) and bio-catalysis was investigated. The results revealed that decreased ethanol yields were achieved when solid loading increased from 5% to 30%. An acceptable ethanol yield of 76.8% was obtained at 20% solid loading. After fermentation, bio-catalysis of xylose remaining in fermentation broth resulted in near 100% xylonic acid (XA) yield at varied solid loadings. To complete the co-product portfolio, oxidation ammoniation of the dissolved lignin successfully transformed it into biodegradable slow-release nitrogen fertilizer with excellent agricultural properties. PMID- 29190598 TI - Evaluation and Management of Kidney Calculi. AB - INTRODUCTION: The recent change in the view towards nephrolithiasis from a benign isolated disease to a disorder associated with numerous systemic and chronic conditions has added to the importance of a more thorough and timely diagnostic and therapeutic intervention. MATERIALS AND METHODS: Both original and review articles found via the PubMed search on recent evaluation and management strategies of urinary calculi were reviewed. These resources were integrated with the authors' knowledge of the field. RESULTS: The emerging evidence attests to the association of nephrolithiasis with many morbid and fatal diseases, such as coronary heart disease, ischemic stroke, hypertension, chronic kidney insufficiency, malignancies, and bone loss, as well as the economic burden of urinary calculus on health system and work force. CONCLUSIONS: Findings of this review justify a timely and comprehensive workup and dietary-therapeutic measures in order to prevent, treat, and control the associated complications of this condition. PMID- 29190597 TI - Insecticidal activity of camphene, zerumbone and alpha-humulene from Cheilocostus speciosus rhizome essential oil against the Old-World bollworm, Helicoverpa armigera. AB - The fast-growing resistance development to several synthetic and microbial insecticides currently marketed highlighted the pressing need to develop novel and eco-friendly pesticides. Among the latter, botanical ones are attracting high research interest due to their multiple mechanisms of action and reduced toxicity on non-target vertebrates. Helicoverpa armigera (Lepidoptera: Noctuidae) is a key polyphagous insect pest showing insecticide resistance to several synthetic molecules used for its control. Therefore, here we focused on the rhizome essential oil extracted from an overlooked Asian plant species, Cheilocostus speciosus (J. Konig) C. Specht (Costaceae), as a source of compounds showing ingestion toxicity against H. armigera third instar larvae, as well as ovicidal toxicity. In acute larvicidal assays conducted after 24h, the C. speciosus essential oil achieved a LC50 value of 207.45ug/ml. GC and GC-MS analyses highlighted the presence of zerumbone (38.6%), alpha-humulene (14.5%) and camphene (9.3%) as the major compounds of the oil. Ingestion toxicity tests carried out testing these pure molecules showed LC50 values of 10.64, 17.16 and 20.86ug/ml, for camphene, zerumbone and alpha-humulene, respectively. Moreover, EC50 values calculated on H. armigera eggs were 35.39, 59.51 and 77.10ug/ml for camphene, zerumbone and alpha-humulene, respectively. Overall, this study represents the first report on the toxicity of C. speciosus essential oil against insect pests of agricultural and medical veterinary importance, highlighting that camphene, zerumbone and alpha-humulene have a promising potential as eco-friendly botanical insecticides.

AB - In this study, the combination of strengthen circulation anaerobic (SCA) and biological aerated filter (BAF) reactor was employed to treat municipal wastewater. Different reflux percentages or gas/water ratios were selected for evaluating the removal performance of contaminants in SCA-BAF system and sequential nitrification and denitrification process in BAF reactor. In general, reflux percentage (200%) and gas/water ratio (3:1) were a relatively suitable operational condition for BAF reactor. The COD, NH3-N, TN concentrations of effluents collected from BAF reactor varied in the ranges of 18-80, 0.2-7.2, 9.1 33.0 mg L-1, respectively. A higher NO3-N concentration in effluents of BAF reactor resulted from the lack of organic carbon resource in wastewater. High throughput sequencing analysis indicated that different nitrification and denitrification bacteria thrived in the BAF reactor. The DO, NO2-N and NO3-N concentrations showed a strong correlation with Nitrospira and Nitrosomonas in bacterial samples outlet (c and e) under gas/water ratio of 3:1.

AB - INTRODUCTION: It may be difficult to differentiate acute kidney injury from chronic kidney disease in patients with no past medical reports of kidney function. This study aimed to investigate the role of serum hyaluronic acid (HA), which is known as a marker of fibrosis, in differential diagnosis of kidney failure. MATERIALS AND METHODS: A total of 90 patients (52 women and 38 mne) admitted to our renal unit with uremia for the first time were included. Serum HA level was measured. The diagnostic role of the test was investigated using the receiver operator curve curves. RESULTS: The mean age of the patients was 54.6 +/ 17.9 years. The diagnosis was chronic kidney disease (CKD) in 41.1%, acute kidney injury (AKI) in 48.9%, AKI on CKD in 6.7% (3 died without a diagnosis). The mean serum HA was significantly higher in the CKD group (146.1 +/- 119.3 ng/mL) than the AKI group (68.9 +/- 69.1 ng/mL; P < .001). Serum HA significantly correlated with proteinuria (r = 0.717, P < .001) and serum albumin level (r = - 0.599, P < .001) in the CKD group only. Serum HA cutoff level of 61 ng/dL had a sensitivity of 82% and specificity of 67% for differential diagnosis of AKI and CKD. CONCLUSIONS: Serum HA level may be used as tool to differentiate AKI from CKD. Further larger studies are warranted to clarify the definite the role of this marker. PMID- 29190596 TI - The impacts of modern-use pesticides on shrimp aquaculture: An assessment for north eastern Australia. AB - The use of pyrethroid and neonicotinoid insecticides has increased in Australia over the last decade, and as a consequence, increased concentrations of the neonicotinoid insecticide imidacloprid have been measured in Australian rivers. Previous studies have shown that non-target crustaceans, including commercially important species, can be extremely sensitive to these pesticides. Most shrimp farms in Australia are predominantly located adjacent to estuaries so they can obtain their required saline water, which support multiple land uses upstream (e.g. sugar-cane farming, banana farming, beef cattle and urbanisation). Larval and post-larval shrimp may be most susceptible to the impacts of these pesticides because of their high surface area to volume ratio and rapid growth requirements. However, given the uncertainties in the levels of insecticides in farm intake water and regarding the impacts of insecticide exposure on shrimp larvae, the risks that the increased use of new classes of pesticide pose towards survival of post-larval phase shrimp cannot be adequately predicted. To assess the potential for risk, toxicity in 20day past hatch post-larval Black Tiger shrimp (Penaeus monodon) to modern use insecticides, imidacloprid, bifenthin, and fipronil was measured as decreased survival and feeding inhibition. Post-larval phase shrimp were sensitive to fipronil, bifenthrin, and imidacloprid, in that order, at concentrations that were comparable to those that cause mortality other crustaceans. Bifenthrin and imidacloprid exposure reduced the ability of post larval shrimp to capture live prey at environmentally realistic concentrations. Concentrations of a broad suite of pesticides were also measured in shrimp farm intake waters. Some pesticides were detected in every sample. Most of the pesticides detected were measured below concentrations that are toxic to post larval shrimp as used in this study, although pesticides exceed guideline values, suggesting the possibility of indirect or mixture-related impacts. However, at two study sites, the concentrations of insecticides were sufficient to cause toxicity in shrimp post larvae, based on the risk assessment undertaken in this study. PMID- 29190595 TI - Chronic exposure to a glyphosate-containing pesticide leads to mitochondrial dysfunction and increased reactive oxygen species production in Caenorhabditis elegans. AB - Glyphosate-containing herbicides are among the most widely-used in the world. Although glyphosate itself is relatively non-toxic, growing evidence suggests that commercial herbicide formulations may lead to increased oxidative stress and mitochondrial inhibition. In order to assess these mechanisms in vivo, we chronically (24h) exposed Caenorhabditis elegans to various concentrations of the glyphosate-containing herbicide TouchDown (TD). Following TD exposure, we evaluated the function of specific mitochondrial electron transport chain complexes. Initial oxygen consumption studies demonstrated inhibition in mid- and high-TD concentration treatment groups compared to controls. Results from tetramethylrhodamine ethyl ester and ATP assays indicated reductions in the proton gradient and ATP levels, respectively. Additional studies were designed to determine whether TD exposure resulted in increased reactive oxygen species (ROS) production. Data from hydrogen peroxide, but not superoxide or hydroxyl radical, assays showed statistically significant increases in this specific ROS. Taken together, these data indicate that exposure of Caenorhabditis elegans to TD leads to mitochondrial inhibition and hydrogen peroxide production.

AB - INTRODUCTION: Idiopathic nephrotic syndrome (INS) is a glomerular disease with completely unclear pathogenesis and different responses to steroid therapy. This study aimed to investigate the role of cytokine genes promoter polymorphisms in steroid therapy responses. MATERIALS AND METHODS: One hundred children with INS and 30 healthy controls were studied. Genotyping of TNF-alpha-G308A single nucleotide polymorphism was done using polymerase chain reaction-restriction fragment length polymorphism method, while of IL-6-G174C single nucleotide polymorphism was done using real-time polymerase chain reaction. RESULTS: The IL 6-G174C exhibited a significantly different genotype distribution among the children with INS compared with the controls (GG versus CC, P = .02; GG versus GC, P = .003; odds ratio [OR], 5.83; 95% confidence interval [CI], 1.64 to 20.70; as well as alleles distribution of G versus C, P ? .001; OR, 7.57; 95% CI, 2.28 to 25.17). With regard to TNF-alpha-G308A genotype, there was no significant difference in genotype distribution of the children with INS compared with the controls, but a significant difference was observed at the alleles level. Comparing the steroid-resistant group with the steroid-sensitive group, significant association was found at genotypic level in case of IL-6-G174C (GG versus CC, P = .03; OR, 5.52; 95% CI, 1.39 to 21.89), but no association was found regarding GG versus GC. At the allelic level of IL-6-G174C, there was no significant association either. CONCLUSIONS: IL-6-G174C and TNFalpha-G308A polymorphisms may affect susceptibility to idiopathic nephrotic syndrome and might affect steroid response in INS patients.

AB - INTRODUCTION: Nephrotoxicity is an important side effects of captopril and gentamicin. This study investigated the prophylactic and protective effects of pomegranate juice (PJ) on the kidney exposed to nephrotoxicity induced by these medications. MATERIALS AND METHODS: Wistar male rats received drinking water (groups 1 to 3) or PJ at doses of 4 mL/kg (group 4), 10 mL/kg (groups 5 and 7), and 15 mL/kg (group 6) for 14 days. Captopril and gentamicin were administrated on days 10 and 14 to groups 1 and 2, respectively, while groups 3 to 6 received both. Group 7 did not receive anything. The serum, urine, and renal tissue parameters were measured after the experiment. RESULTS: Group 1 (captopril) had a higher malondialdehyde level than groups 4, 5, 6, and 7 with PJ (P <0.05), and group 3 (captopril and gentamicin) showed the most significant malondialdehyde level compared to other groups (P < .001). Group 5 (captopril, gentamicin, and PJ, 10 mL/kg) had the most significant sodium excretion compared to other groups (P < .001), and group 2 (gentamicin) showed the highest potassium absolute excretion (P < .001). The instability of the renal index was observed during the experiment for the groups receiving drinking water, while no significant changes were observed in the groups receiving PJ. CONCLUSIONS: The prophylactic consumption of PJ for 14 days could show nephroprotective effects by reducing oxidative stress and potassium depletion. It could also lead to the stabilization of kidney function during this period despite using captopril and gentamicin. PMID- 29190607 TI - Effect of Paricalcitol on Bone Density After Kidney Transplantation: Analysis of 2 Transplant Centers. AB - INTRODUCTION: The Kidney Disease: Improving Global Outcomes Clinical Practice Guidelines on the management of bone disease in patients with chronic kidney disease recommend periodic measurement of serum calcium, phosphorus, vitamin D, and parathyroid hormone levels after kidney transplantation, with the frequencies that will vary according to the severity of bone disease and graft function. Paricalcitol, a selective vitamin D receptor activator, is indicated in the prevention and treatment of secondary hyperparathyroidism. MATERIALS AND METHODS: We retrospectively evaluated the effect of treatment with paricalcitol among our kidney transplant recipients. We monitored the effect of paricalcitol on bone density; the plasma levels of parathyroid hormone, calcium, and phosphorus; and proteinuria and calciuria. Comparisons were made between these parameters before treatment and 12 months after treatment. RESULTS: Eighty-eight kidney transplant recipients with a mean age at the time of transplantation of 47.1 +/- 10.5 years were receiving paricalcitol. On average, paricalcitol was included into the treatment for 48 months from transplantation (median, 27 months). The patients had significantly improved bone density (P < .001), significantly lower parathyroid hormone levels (P < .001), and significantly decreased proteinuria (P = .02) after 12 months of treatment. During the treatment with paricalcitol, the immunosuppressive therapy, dose of prednisone, body mass index, and vitamin D levels had not significantly changed. Nor had any significant change occurred to graft function. CONCLUSIONS: Paricalcitol is an effective therapy for secondary hyperparathyroidism in kidney transplant recipients.

AB - INTRODUCTION: Calcineurin-binding protein 1 (Cabin1) interacts with calcineurin and p53, but its function in renal tubular epithelial cell (RTEC) is unclear. We established 5/6 nephrectomized rats and angiotensin II-induced injury to the RTECs in vitro, to observe the expression of Cabin1 during RTEC injury. MATERIALS AND METHODS: Sprague-Dawley rats were sacrificed at 4 and 8 weeks after 5/6 nephrectomy. Renal pathology and mitochondrial damage were detected by light and electrical microscope. The distribution of E-cadherin and alpha-smad were detected by indirect immunofluorescence staining. Cabin1 protein expression was detected by Western blot. RESULTS: Obvious tubulointerstitial fibrosis was found in the nephrectomized rats at 8 weeks after 5/6 nephrectomy, accompanied by the increasing levels of creatinine, as well as the disruption of E-cadherin and overexpression of alpha-smad in RTECs. Moreover, the mitochondria became swollen and mitochondrial cristae were disrupted and poorly defined in the RTECs. Compared to the sham-operated rats, Cabin1 protein expression was significantly increased at 8 weeks after 5/6 nephrectomy, while angiotensin II-induced Cabin1 protein expression significantly increased 48 hours after stimulation in normal rat kidney epithelial cells. CONCLUSIONS: Injury to the RTEC and Cabin1 protein overexpression occurred in a time-dependent manner both in vitro and in vivo. Cabin1 may become a potential molecular target in RTEC injury. PMID- 29190608 TI - Seropositivity of Rheumatoid Arthritis Specific Tests in a Patient With Nephrotic Syndrome: Successful Treatment With Rituximab. AB - Presentation of rheumatoid arthritis (RA) with renal complications is very rare without articular symptoms. We here report a case of a 23-year-old woman, presenting with the edema of the extremities, no relevant previous medical history, and the features of acute tubular injury in her percutaneous kidney biopsy. Following the incidental notification of a positive rheumatoid factor test, other immunologic tests including anticyclic citrullinated peptide and antimutated citrullinated vimentin were performed, the positive results of which favored the diagnosis of RA. Administration of rituximab led to the complete remission of the disease. Six weeks later, along with steroid dose reduction, the symptoms of arthralgia was observed, which was managed with methotrexate. Nephrotic syndrome could be rarely the first manifestation of RA, and screening of specific RA autoantibodies might be considered as part of diagnostic evaluations in nephrotic syndrome workup. PMID- 29190605 TI - Evaluation of Renal Toxicity of Colistin Therapy With Neutrophil Gelatinase associated Lipocalin: a Biomarker of Renal Tubular Damage. AB - INTRODUCTION: Nephrotoxicity has been a concern with new dosing regimens of colistin. This study was designed to compare nephrotoxicity of high dose and conventional dose of colistin and the ability of detecting it using neutrophil gelatinase-associated lipocalin (NGAL). MATERIALS AND METHODS: A randomized clinical trial was carried out on 40 patients with multidrug-resistant gram negative infections assigned into 2 groups to receive high and conventional doses of colistin. Blood samples were taken 4 times for measuring serum NGAL. The incidence of acute kidney injury was also evaluated based on the risk, injury, failure, loss, end-stage renal disease (RIFLE) criteria. RESULTS: Baseline levels of NGAL were not significantly different between the patients on the high dose and conventional dose of colistin. The mean NGAL levels on day 10 were 762.14 +/- 415.44 pg/mL and 623.67 +/- 272.61 pg/mL, respectively. However, between-group analysis did not show a significant difference in the NGAL levels. The prevalence of acute kidney injury was 60% and 15% based on the RIFLE criteria, in the high dose and conventional-dose groups, respectively (P = .003). CONCLUSIONS: Although colistin-induced nephrotoxicity was not confirmed with NGAL levels, our findings, however, showed a higher incidence of acute kidney injury associated with high dose colistin, defined by the RIFLE criteria. Higher levels of NGAL in the acute kidney injury patients were associated with high-dose regimen of colistin. PMID- 29190606 TI - Association Between Klotho Gene Polymorphism and Markers of Bone Metabolism in Patients Receiving Maintenance Hemodialysis in Iran. AB - INTRODUCTION: Some genetic variations of Klotho have been reported as a risk factor for calcification and hyperphosphatemia in chronic kidney disease. Klotho polymorphism is also associated with outcome in patients receiving hemodialysis. This study aimed to evaluate the relationship between Klotho single nucleotide polymorphism (SNP) and bone metabolism as an early prognostic measure for chronic kidney disease. Materials and Methods. Sixty patients receiving hemodialysis and 60 age-matched controls were enrolled in the study of the assessment of 2 types of Klotho polymorphism (G395A and C1818T). Serum biochemical parameters, including calcium, phosphate, urea, creatinine, parathyroid hormone, and 25 hydroxyvitamin D3 were measured. Results. The frequency of being A carriers suggested marginal significances between the groups (GA and AA, 30% versus GG, 18.3%, P = .06), but such significant results were not found for the T allele carriers (CT and TT, 76.6% versus CC, 76.6%, P > .99). Homozygote and heterozygote individuals for the A allele at G395A SNP (A allele carriers) were more likely to be on hemodialysis (odds ratio, 1.43; 95% confidence interval, 0.60 to 3.30), but this association was not true for T allele carriers of C1818T SNP. Parathyroid hormone and serum calcium, phosphate, creatinine, and urea showed prominently higher levels in the patients receiving hemodialysis compared with control individuals. CONCLUSIONS: The A allele of the G395A polymorphism of Klotho, which emerges the higher levels of phosphate, may be associated with the risk of mortality in Iranian patients receiving hemodialysis. PMID- 29190612 TI - Assessment of Bronchial Obstruction Using Lateral Pressure Measurement during Bronchoscopy. AB - BACKGROUND: In patients with bronchial obstruction estimating the location of the maximal obstruction is crucial for guiding interventional bronchoscopy. However, flow-volume curves cannot discriminate between the right and left lungs. OBJECTIVES: The aim of this study was to physiologically evaluate bronchial obstruction during interventional bronchoscopy. METHODS: We prospectively measured lateral airway pressure (Plat) at either side of the obstruction using a double-lumen catheter (pressure-pressure [P-P] curve) simultaneously to assess the degree of bronchial obstruction in 22 patients. The shape of the P-P curve was assessed to confirm the site of maximal obstruction. RESULTS: In the experimental study, Plat was uniform between both bronchi in the normal model. For the unilateral and bilateral obstruction models, a phase shift was only seen for the more obstructed side. In healthy subjects, the angle of the P-P curve was close to 45 degrees and linear in shape. In patients with bronchial obstruction, the angle was much smaller but approached 45 degrees after the bronchoscopic procedure. The degree of bronchial obstruction was significantly correlated with the angle of the P-P curve (r = -0.51, p < 0.01). Dyspnea significantly increased when the airway lumen was obstructed by more than 60% (p < 0.0001), and when the P-P curve appeared loop-shaped (p < 0.01). CONCLUSIONS: The shape of the P-P curve could be used to detect the site of maximal obstruction for the optimal positioning of the stent and assess the need for additional procedures in real time in patients with bronchial obstruction. PMID- 29190604 TI - Metabolic Response to Mulberry Extract Supplementation in Patients With Diabetic Nephropathy: a Randomized Controlled Trial. AB - INTRODUCTION: This study aimed to evaluate the effects of mulberry extract administration on markers of insulin metabolism, lipid concentrations, and biomarkers of inflammation and oxidative stress in patients with diabetic nephropathy (DN). MATERIALS AND METHODS: Sixty patients were randomly allocated into 2 groups to receive either 300 mg/d of mulberry extract (n = 30) or placebo (n = 30), twice per day for 12 weeks. Fasting blood samples were taken at the onset of the study and 12 weeks after supplementation to examine markers of insulin metabolism, lipid concentrations, and biomarkers of inflammation and oxidative stress. RESULTS: Mulberry extract, compared to placebo, resulted in significant reductions in serum triglycerides (-37.3 +/- 64.7 mg/dL versus 3.0 +/ 78.8 mg/dL, P = .03) and very low-density lipoprotein cholesterol (-7.4 +/- 12.9 mg/dL versus 0.6 +/- 15.8 mg/dL, P = .03), and a significant increase in high density lipoprotein cholesterol concentration (0.5 +/- 4.0 mg/dL versus -2.0 +/- 5.0 mg/dL, P = .03). Other significant changes were in serum high-sensitivity C reaction protein (-2.3 +/- 4.5 ug/mL versus -0.1 +/- 2.2 ug/mL, P = .02), plasma glutathione (87.8 +/- 159.7 umol/L versus -24.2 +/- 138.8 umol/L, P = .005) and malondialdehyde (-0.03 +/- 0.5 umol/L versus 0.7 +/- 1.0 umol/L, P < .001). Conclusions. These findings showed that mulberry extract administration had favorable effects on serum lipids, HSCRP, glutathione, and malondialdehyde levels in DN patients; however, it did not affect markers of insulin metabolism or biomarkers of inflammation and oxidative stress. PMID- 29190613 TI - N-Terminal Prohormone of Brain Natriuretic Peptide but not C-Terminal Pre-Pro Vasopressin (Copeptin) Level is Associated with the Response to Antihypertensive Therapy in Haemodialysis Patients. AB - BACKGROUND/AIMS: Volume overload, frequently clinically asymptomatic is considered as a causative factor limiting the effectiveness of antihypertensive therapy in haemodialysis (HD) patients. Therefore, the aim of this study was to assess plasma levels of N-terminal fragment of the prohormone brain natriuretic peptide (NT-proBNP) and a C-terminal portion of the precursor of vasopressin (CT proAVP, copeptin), surrogate markers of volume overload in HD patients in relation to the number of antihypertensive drugs used in the hypertension treatment. METHODS: One hundred and fifty adult HD patients (92 males) were enrolled into this study. Clinical data concerning blood pressure (BP) measurements prior haemodialysis session and pharmacotherapy were collected from all patients. In addition to routine laboratory parameters, plasma levels of NT proBNP and CT-proAVP were measured, and daily sodium and water consumption were estimated with a portion-size food frequency questionnaire. RESULTS: Among 145 (96.7%) hypertensive HD patients, 131 were receiving antihypertensive medication. Despite antihypertensive therapy, 31.0% had inadequate BP control. Plasma concentration of NT-proBNP was associated with systolic (R=0.19; p=0.02) but not diastolic BP values and with the number of received antihypertensive drugs (R=0.21; p=0.01). The highest NT-proBNP values were observed in patients receiving 3 or more antihypertensive drugs. In contrast, no significant correlation was found between plasma CT-proAVP concentrations and BP values as well as and the number of antihypertensive drugs. Receiver operator curve analysis showed that NT-proBNP values over 13,184 pg/mL predicted the use of at least 3 antihypertensive drugs in maximal doses in the therapy of hypertension, similar analyses performed for CT-proAVP showed much less specificity. CONCLUSIONS: 1. Increased levels of NT-proBNP seems to be a better biomarker of multidrug antihypertensive therapy requirement than CT-proAVP. 2. Whether estimation of NT-proBNP in these patients will be also better biomarker than copeptin in the prediction of cardiovascular complications related to hypertension needs further investigations. PMID- 29190619 TI - Ruptured de novo Aneurysm following Gamma Knife Surgery for Arteriovenous Malformation: Case Report. AB - Stereotactic radiosurgery is a well-known treatment tool for arteriovenous malformations (AVMs). The method has high validity and minimal invasiveness, but late-onset problems involving tumor formation and vasculopathy induced by radiation have been reported. We present a rare case of a radiation-induced ruptured de novo aneurysm following Gamma Knife surgery (GKS) for an AVM. A 17 year-old, right-handed male underwent GKS for AVM at the left parietal lobe. After 3 years, a follow-up angiogram showed a residual AVM at the angular gyrus. Then, a 2nd GKS was performed for the residual lesion. Six years after the 1st GKS, the AVM disappeared on the angiogram. Seven years later, he suffered a sudden onset of headache. A left carotid angiogram revealed a ruptured aneurysm at the M2-M3 junction of the middle cerebral artery parietal branch. Coil embolization was performed, and the aneurysm was occluded. The patient was discharged without any neurologic deficits. PMID- 29190620 TI - Four Novel NR5A1 Mutations in 46,XY Gonadal Dysgenesis Patients Including Frameshift Mutations with Altered Subcellular SF-1 Localization. AB - 46,XY gonadal dysgenesis (46,XY GD) is a disorder of sexual development caused by mutations in genes involved in early gonadal development (bipotential gonads) and testis differentiation. In 46,XY GD individuals, mutations of the SRY gene are detected most frequently, followed by mutations in the NR5A1 (SF-1) gene, but in a lot of cases, the underlying molecular mechanism remains elusive. In this study, we retrospectively performed sequence analyses of the NR5A1 (SF-1) gene in 84 patients with complete, partial, and syndromic forms of 46,XY GD. In total, 7 heterozygous mutations were found in 6 of 84 patients (7.1%). Among these, we identified 4 mutations that, to the best of our knowledge, have not been reported before (c.268G>T, c.369del, c.871-1G>C, and c.893T>C). Transfection of different mutations revealed altered subcellular localization of the mutant SF-1 protein in the case of the frameshift mutations, indicating an impaired protein function. In conclusion, we present 4 novel mutations of the NR5A1 gene associated with 46,XY GD together with in vitro data pointing towards a possible functional impairment of the mutant SF-1 proteins. PMID- 29190614 TI - How Survey Design Affects Monkey Counts: A Case Study on Individually Recognized Spider Monkeys (Ateles geoffroyi). AB - The fast movement and high degree of fission-fusion dynamics of spider monkeys (Ateles spp.) make them notoriously difficult to survey. We examined which aspects of survey design affect spider monkey sightings along transects in a group of individually recognized spider monkeys (Ateles geoffroyi) in Punta Laguna, Yucatan, Mexico. We calculated the number of monkeys and subgroups sighted per transect walk. Using generalized linear models, we found no effect of the number of observers, transect type (new vs. existing), walking speed, or time of day on individual monkey counts or subgroup counts. Recounting of individuals was relatively rare and occurred when transects were walked relatively slowly. We missed more young than adult monkeys. The group composition based on survey data was similar to the known group composition. Based on our findings we recommend that surveys performed on relatively flat terrain be conducted at speeds similar to or faster than the moving speed of spider monkeys to minimize recounting of individuals and that young:adult female ratios based on survey data be interpreted as conservative indicators of population health. The novel methods presented to determine sources of bias in population estimates are applicable to a wide range of primates that are difficult to survey. PMID- 29190616 TI - Apatinib Inhibits Angiogenesis Via Suppressing Akt/GSK3beta/ANG Signaling Pathway in Anaplastic Thyroid Cancer. AB - BACKGROUND/AIMS: Anaplastic thyroid carcinoma (ATC) is one of the most lethal human malignancies, and there is no efficient method to slow its process. Apatinib, a novel tyrosine kinase inhibitor (TKI), has been confirmed for its efficacy and safety in the treatment of advanced gastric carcinoma patients. However, the effects of Apatinib in ATC are still unknown. METHODS: In this study, we explored the effects and mechanisms of Apatinib on tumor growth and angiogenesis in vitro and in vitro in ATC cells. Angiogenesis antibodies array was utilized to detect the expression of angiogenesis-related genes after Apatinib treatment in ATC cells. In addition, we used Akt activator, Akt inhibitor and GSK3beta inhibitor to further study the mechanism for how Apatinib suppressed angiogenesis. RESULTS: Apatinib treatment could suppress the growth of ATC cells in a dose- and time-dependent manner via inducing apoptosis and blocking cell cycle progression at G0/G1 phase. Moreover, Apatinib treatment decreased the expression of angiogenin (ANG) and inhibited angiogenesis of ATC cells in vitro and in vitro. We further confirmed that recombinant human ANG (rhANG) significantly abrogated Apatinib-mediated anti-angiogenic ability in ATC cells. Additionally, Apatinib treatment decreased the level of p-Akt and p GSK3beta. Moreover, the Apatinib-mediated decrease of ANG and anti-angiogenic ability were partly reversed when an Akt activator, SC79, was administered. Furthermore, the anti-angiogenic ability of Apatinib can be enhanced in the presence of Akt inhibitor, and the inhibition of GSK3beta attenuated the anti angiogenic ability of Apatinib. CONCLUSION: Our results demonstrated that Apatinib treatment inhibited tumor growth, and Apatinib-induced suppression of Akt/GSK3beta/ANG signaling pathway may play an important role in the inhibition of angiogenesis in ATC, supporting a potential therapeutic approach for using Apatinib in the treatment of ATC. PMID- 29190615 TI - The Key Roles of GSK-3beta in Regulating Mitochondrial Activity. AB - Glycogen synthase kinase-3beta (GSK-3beta), a serine/threonine protein kinase, has been reported to show essential roles in molecular pathophysiology of many diseases. Mitochondrion is a dynamic organelle for producing cellular energy and determining cell fates. Stress-induced translocated GSK-3beta may interact with mitochondrial proteins, including PI3K-Akt, PGC-1alpha, HK II, PKCepsilon, components of respiratory chain, and subunits of mPTP. Mitochondrial pool of GSK 3beta has been implicated in mediation of mitochondrial functions. GSK-3beta exhibits the regulatory effects on mitochondrial biogenesis, mitochondrial bioenergetics, mitochondrial permeability, mitochondrial motility, and mitochondrial apoptosis. The versatile functions of GSK-3beta might be associated with its wide range of substrates. Accumulative evidence demonstrates that GSK 3beta inactivation may be potentially developed as the promising strategy in management of many diseases, such as Alzheimer's disease (AD) and Parkinson's disease (PD). Intensive efforts have been made for exploring GSK-3beta inhibitors. Natural products provide us a great source for screening new lead compounds in inactivation of GSK-3beta. The key roles of GSK-3beta in mediation of mitochondrial functions are discussed in this review. PMID- 29190622 TI - Classifying Apnea of Prematurity by Transcutaneous Electromyography of the Diaphragm. AB - BACKGROUND: Treatment of apnea is highly dependent on the type of apnea. Chest impedance (CI) has inaccuracies in monitoring respiration, which compromises accurate apnea classification. Electrical activity of the diaphragm measured by transcutaneous electromyography (EMG) is feasible in preterm infants and might improve the accuracy of apnea classification. OBJECTIVES: To compare the accuracy of apnea classification based on diaphragmatic EMG (dEMG) and CI tracings in preterm infants. METHODS: Fifteen cases of central apnea, 5 of obstructive apnea, and 10 of mixed apnea were selected from recordings containing synchronized continuous tracings of respiratory inductive plethysmography (RIP), airway flow, heart rate (HR), oxygen saturation (SpO2), and breathing activity measured by dEMG and CI. Twenty-two assessors (neonatologists, pediatricians-in-training, and nurses) classified each apnea twice; once based on dEMG, HR, and SpO2 tracings, and once based on CI, HR, and SpO2. The assessors were blinded to the type of respiratory tracing (dEMG or CI) and to the RIP and flow tracings. RESULTS: In total 1,320 assessments were performed, and in 71.1% the apnea was classified correctly. Subgroup analysis based on respiratory tracing showed that 74.8% of the dEMG tracings were classified correctly compared to 67.3% of the CI tracings (p < 0.001). This improved apnea classification based on dEMG was present for central (86.7 vs. 80.3%, p < 0.02) and obstructive (56.4 vs. 32.7%, p < 0.001) apnea. The improved apnea classification based on dEMG tracing was independent of the type of assessor. CONCLUSION: Transcutaneous dEMG improves the accuracy of apnea classification when compared to CI in preterm infants, making this technique a promising candidate for future monitoring systems. PMID- 29190611 TI - Upregulated TRIM11 Exerts its Oncogenic Effects in Hepatocellular Carcinoma Through Inhibition of P53. AB - BACKGROUND/AIMS: The tripartite motif containing (TRIM) family plays crucial roles in tumor development and progression. However, little is known about the function and mechanism of TRIM11 in hepatocellular carcinoma (HCC). METHODS: The expression levels of TRIM11 were examined by real-time PCR, Western blot and Immunohistochemical (IHC) staining. TRIM11 knockdown cells were produced by lentivirus infection, and functional assays, such as MTT, colony formation assay, migration and invasion assays and a xenograft tumor model were used to investigate the role of TRIM11 in HCC. We also determined the effect of TRIM11 on p53 signaling and its downstream molecules. RESULTS: We found that TRIM11 mRNA and protein levels were significantly increased in HCC tissues as compared with normal tissues; increased levels correlated with poor patient survival. By loss- and gain-of-function investigations, knockdown of TRIM11 suppressed cell proliferation, migration, invasion in vitro and tumor growth in vivo. Moreover, TRIM11 negatively regulated p53 expression. Knockdown of p53 abrogated the in vitro and in vivo biological functions of TRIM11 shRNA in HCC cells. CONCLUSIONS: These data show that TRIM11 exerts its oncogenic effect in HCC by downregulating p53 both in vitro and in vivo. Our data provide new insights into the pathogenesis of HCC and indicate that TRIM11 may serve as a new therapeutic target for HCC treatment. PMID- 29190621 TI - NSCLC Patients Harbouring Rare or Complex EGFR Mutations Are More Often Smokers and Might Not Benefit from First-Line Tyrosine Kinase Inhibitor Therapy. AB - BACKGROUND: Generally, tyrosine kinase inhibitor (TKI) therapy is recommended in first-line treatment of patients with advanced non-small cell lung cancer (NSCLC) harbouring a classic epidermal growth factor receptor (EGFR) mutation. However, the response of patients with rare or complex EGFR mutations to TKI treatment is not predictable, nor is the prognosis for such patients. OBJECTIVES: In cases of rare or complex EGFR mutations, the right approach to therapy remains challenging. That is why we sought to analyse the characteristics as well as the prognosis and the response to TKI treatment of patients with rare or complex EGFR mutations. PATIENTS AND METHODS: 343 NSCLC patients tested for EGFR mutation at a German lung cancer centre were analysed for age, gender, and smoking status as well as for the mutation status. For 12 patients with rare and complex mutations, response to TKI treatment was described. RESULTS: 282 of all patients had a wild type EGFR, whereas 61 harboured an EGFR mutation. 32 of these were classic mutations, followed by 16 rare and 7 complex mutations. EGFR mutations were significantly more frequent in women. Patients with rare or complex mutations were significantly more often smokers compared to those with classic EGFR mutations. Furthermore, rare and complex mutations were less responsive to TKI therapy. CONCLUSION: Patients with rare or complex EGFR mutations differ from those with classic mutations in terms of smoking status and response to TKIs. As these mutations may not respond well to TKI therapy, first-line TKIs should not be automatically chosen based on the sole presence of an EGFR mutation. PMID- 29190623 TI - Axial Length/Corneal Radius of Curvature Ratio Assessment of Posterior Sclera Reinforcement for Pathologic Myopia. AB - PURPOSE: The aim of this study was to assess the axial length/corneal radius of curvature ratio changes after posterior scleral reinforcement (PSR) for pathologic myopia. PROCEDURES: This study enrolled 32 pathologically myopic eyes treated with PSR and 35 untreated pathologically myopic eyes. Axial length, refractive error, best corrected visual acuity, corneal radius of curvature, and the axial length/corneal radius of curvature ratio were evaluated during the 1 year follow-up. RESULTS: There were no statistical differences in each parameter between the 2 groups at baseline. Significant differences were found between the 2 groups in both axial elongation and best corrected visual acuity improvement. The average axial length/horizontal corneal radius of curvature ratio significantly decreased in the PSR group. CONCLUSION: The PSR surgery can effectively delay the axial elongation in pathological myopia. Axial length/horizontal corneal radius of curvature ratio significantly decreased, which may indicate less myopic progression after surgery. PMID- 29190624 TI - Extreme Surgical Maneuvers in Fungal Endophthalmitis. AB - PURPOSE: To present the different evolution of 2 cases of endophthalmitis caused by Fusarium solani, an aggressive filamentous fungus, depending on the medical and surgical treatment performed. METHODS: We present 2 cases of endophthalmitis caused by Fusarium solani. Topical, intrastromal, intravitreal, and systemic antifungal treatment (natamycin, voriconazole, amphotericin B) failed in both cases. Corneal perforation took place in one of them, being unsuccessfully treated with cyanoacrylate and several amniotic membrane transplants. It became necessary to perform a hot penetrating keratoplasty (PK) in both patients. The lenses were removed, and the microbiological analysis showed their colonization by Fusarium solani. In one of the cases, a second PK and a more aggressive pars plana vitrectomy (PPV) were performed after corneal recurrence detected by confocal microscopy, as well as the following therapeutic intra- and postoperative maneuvers: anterior chamber washing with povidone-iodine 5% for 1 min; iridectomy of the infiltrated regions; aspiration of the fungal colonies with vitrector; several air/fluid/amphotericin/voriconazole exchanges during PPV; endodiathermy and endophotocoagulation of the chorioretinitis foci; and intrascleral angle injections of voriconazole and amphotericin. RESULTS: These were the only cases of endophthalmitis caused by Fusarium attended to at our hospital during the last 10 years. In the case in which PPV was performed without those maneuvers, endophthalmitis rapidly recurred in a more aggressive way, so finally it became necessary to eviscerate the globe. On the other hand, in the patient who underwent PPV with the specific surgical maneuvers and postoperative procedures described above, we could preserve the eye and even a vision of hand motion without an intraocular lens. CONCLUSIONS: The main objectives of these surgical procedures are to control the fungal infection and to preserve the ocular globe. It is essential to eliminate all ocular structures (iris, lens, vitreous, etc.) affected by this strain of fungus in order to reduce the risk of recurrence. When indicated, early surgery with the appropriate maneuvers detailed above may make an evisceration unnecessary and even recover some visual acuity. PMID- 29190627 TI - Gender-Related Differences and Short-Term Outcome of Stroke: Results from a Hospital-Based Registry in Sub-Saharan Africa. AB - BACKGROUND: Studies suggest that sex differences have an impact on patients with stroke, but existing data in Africa remain inconclusive about this inference. OBJECTIVES: To study sex differences in terms of the clinical profile and short term outcome of stroke in the Douala General Hospital, Cameroon. METHODS: A hospital-based prospective cohort study was carried out in a tertiary care hospital over an 8-year period, which included all patients admitted for confirmed acute stroke. Information about the history of stroke with emphasis on clinical profile and outcome was collected. Descriptive statistics, t test, and chi square test were used for comparisons, while the Kaplan-Meier curve was used for survival rate analysis. RESULTS: Of the 818 patients included, 455 (55.6%) were male patients. When compared to males, female patients are more likely to experience a stroke at an older age (mean age 62.3 +/- 14.1 vs. 58.4 +/- 12.9 years, p < 0.001), to be unmarried, to remain unemployed, and to have higher rates of cardio-embolic stroke (p = 0.049), body mass index (p = 0.031), altered levels of consciousness at presentation (p = 0.005), higher mean HDL cholesterol levels (p = 0.001), and in-hospital complications (p = 0.011), especially urinary tract infections (p = 0.018). Males were more likely to have health insurance, to smoke, to consume alcohol (p < 0.001), and to have higher rates of dysarthria (p = 0.004), higher mean uric acid (p = 0.013), and creatinine (p < 0.001) concentrations. Ischemic and hemorrhagic strokes were more prevalent in men (p = 0.003). There are no sex differences in terms of stroke severity, length-of hospital stay, case fatality, and functional outcome on admission. CONCLUSIONS: Sex differences exist in the clinical profile of stroke but not in the outcome. Knowledge of these differences could help influence stroke prevention, thereby improving stroke burden in Africa. PMID- 29190631 TI - A Retrospective Review of the Diagnostic and Management Challenges of Mirizzi Syndrome at the Singapore General Hospital. AB - BACKGROUND: Mirizzi syndrome (MS) occurs when gallstone impaction in Hartmann's pouch results in extrinsic obstruction of the common bile duct, and fistulation may occur. METHODS: We retrospectively reviewed electronic records of patients surgically treated for MS from November 2001 to June 2012. Patient presentations, diagnostic methods, treatments and complications were recorded. RESULTS: Sixty four patients were grouped according to a classification proposed by Beltran et al. [World J Surg 2008; 32: 2237-2243]. Forty-three (66.2%), 18 (27.7%) and 3 (4.6%) patients were classified as types I, II, and III respectively. Magnetic resonance-cholangiopancreaticography was the most sensitive imaging modality, suggesting MS in 24 (88.9%), followed by CT scan (40%) and ultrasonography (11.4%). Forty-four underwent Endoscopic-retrograde-cholangiopancreaticography and 29 (65.9%) suggested the presence of MS. MS was accurately diagnosed pre operatively in 48 (73.8%) patients. In type I, 40 (93.0%) patients underwent cholecystectomy, while 3 required hepaticojejunostomy. In type II, 12 (66.7%) underwent cholecystectomy and 5 (27.8%) required hepatico-enteric anastomosis. In type III, 1 underwent cholecystectomy and 2 (66.7%) required hepatico-enteric anastomosis. Laparoscopic cholecystectomy was attempted in 20 (30.8%) patients and 13 (65.0%) required conversion. Twenty-nine (44.6%) underwent intra-operative cholangioscopy, 30 (46.2%) underwent intra-operative-cholangiogram and 41 (63.1%) underwent intra-operative T-tube placement. Six (9.2%) experienced intra operative complications, 12 (18.5%) experienced post-operative complications and 10 (15.4%) experienced late complications. CONCLUSION: MS is a challenging condition and multimodal diagnostic approach has the greatest yield in achieving accurate pre-operative diagnosis. If suspicion is high, a trial of laparoscopic dissection with low threshold for open conversion is recommended. PMID- 29190632 TI - Tinnitus Is Associated with a Higher Risk of Benign Brain Tumors: A Nationwide, Population-Based Secondary Cohort Study of Young and Middle-Aged Adults. AB - BACKGROUND: It remains unclear whether tinnitus is associated with a higher risk of benign or malignant brain tumors in humans. Therefore, the aim of this secondary study was to investigate the risk of brain tumors in adult with tinnitus using data from a nationwide health claims research database. METHODS: Patients aged 20-50 years who were newly diagnosed with tinnitus were identified from the Taiwan's National Health Insurance Research Database and they served as the study cohort. A comparison cohort was formed by using patients without tinnitus from the same database with frequency matching (4: 1) by 10-year age interval and gender to the patients in the tinnitus cohort. Cox proportional hazards models were used to calculate the adjusted hazard ratios (AHR) for benign and malignant brain tumors in patients with tinnitus, adjusting for age, gender, and comorbidities. RESULTS: There were 15,819 patients in the tinnitus cohort and 63,276 in the comparison cohort. A significantly higher proportion of patients with tinnitus had benign brain tumor (p = 0.003) and all 11 comorbid conditions (p < 0.001) compared to those without tinnitus. Cox proportional hazards regression analysis performed on the basis of age, gender, and the 11 comorbidities revealed that tinnitus was independently associated with a higher risk for benign brain tumor (AHR 1.65, 95% CI 1.24-2.20, p = 0.001) and but not with malignant brain tumors (AHR 1.66, 95% CI 0.93-2.94, p = 0.085). CONCLUSIONS: Findings from this secondary cohort analysis indicated that tinnitus is associated with a higher risk of benign brain tumors. PMID- 29190629 TI - Suppressed Adiponectin Levels and Increased Adiponectin Response to Oral Glucose Load in Lean Women with Severe Acne Normalizes after Isotretinoin Treatment. AB - BACKGROUND/AIM: Isotretinoin, the drug of choice for severe acne, might be associated with a decrease in insulin sensitivity. Adiponectin is an adipose tissue-derived protein that increases insulin sensitivity. In this study, we aimed to investigate adiponectin levels in postadolescent severe acne and the effect of isotretinoin on adiponectin levels. METHODS: Participants included 18 female patients with severe acne and 18 healthy women matched for age and body mass index (BMI). Acne patients completed a 6-month isotretinoin treatment. Anthropometric measurements, serum adiponectin, lipids, fasting glucose, fasting insulin, and homeostatic model assessment for insulin resistance (HOMA-IR) were determined, and a standard 2-h oral glucose tolerance test (OGTT) was performed in healthy women once and in patients with acne before and after treatment. RESULTS: At baseline, patients with acne had significantly lower serum adiponectin levels than controls. Isotretinoin treatment resulted in a significant increase in weight, BMI, and triglyceride and adiponectin levels. Glucose metabolism markers in patients with acne and controls were similar at baseline and did not change after treatment. Baseline OGTT in acne patients revealed an increased adiponectin response at 2 h, which was not present in healthy controls. Remarkably, this OGTT-induced adiponectin increment in acne patients was diminished after isotretinoin treatment. CONCLUSION: Adiponectin levels are differently regulated in women with severe acne and healthy controls in that circulating basal levels in patients are suppressed and show an increase in response to oral glucose load. Suppression of baseline adiponectin ameliorates after 6 months of isotretinoin treatment, reaching levels similar to those of healthy controls. PMID- 29190635 TI - Neonatal lupus - case series of a tertiary hospital. AB - Neonatal lupus (NL) is a very rare condition with an estimated incidence of 1 in 20.000 pregnancies. It is caused by the transplacental passage of autoantibodies anti-Ro/SSA, antiSa/SSB antibodies and/or anti-U1 RNP antibodies into the fetal circulation. The mother may be completely asymptomatic or have a known inflammatory rheumatic disease, such as Sjogren syndrome (SS) or Systemic Lupus Erythematosus (SLE). Clinical manifestations are diverse, being the most common cutaneous and cardiac. The authors present a case series of eight cases diagnosed with NL between January 2008 and December 2016 in a tertiary hospital and a brief revision of the literature. PMID- 29190628 TI - Cord Blood Biomarkers of Cardiac Dysfunction and Damage in Term Growth-Restricted Fetuses Classified by Severity Criteria. AB - OBJECTIVE: To assess cardiovascular function and damage in term small-for gestational-age (SGA) and intrauterine growth-restricted (IUGR) fetuses by echocardiography and biomarkers in cord blood. METHODS: This was a cohort study including 60 normal fetuses and 47 term small fetuses subclassified as small for gestational age (SGA) with estimated fetal weight (EFW) between the 3rd and 9th centiles and normal fetoplacental Doppler (n = 14) or intrauterine growth restriction (IUGR, n = 33) if EFW <3rd centile or EFW <10th centile together with cerebroplacental ratio <5th and/or mean uterine artery pulsatility index >95th centile. Fetal echocardiography included left myocardial performance index (MPI) and annular plane systolic excursion. Fetal B-type natriuretic peptide (BNP), troponin-I, heart-type fatty acid-binding proteins (H-FABP), and homocysteine concentrations were measured in cord blood collected at delivery. RESULTS: Both SGA and IUGR cases presented echocardiographic signs of systolic and diastolic dysfunction with increased MPI (mean controls 0.43 [SD 0.12], SGA 0.47 [0.03], and IUGR 0.57 [0.08], p < 0.01) and decreased mitral annular plane systolic excursion (controls 6.0 mm [1.0], SGA 5.5 mm [0.6], and IUGR 4.9 mm [0.8], p = 0 01). IUGR fetuses presented increased levels of cord blood BNP (controls 17.2 pg/mL [11.5], SGA 22.4 pg/mL [10.7], and IUGR 31.2 pg/mL [26.8], p < 0.01). Troponin I was increased in both SGA and IUGR cases (controls 0.004 ng/mL [0.007], SGA 0.012 ng/mL [0.02], and IUGR 0.018 ng/mL [0.05], p < 0.01). H-FABP and homocysteine showed similar values among groups. CONCLUSIONS: Cardiac dysfunction and cell damage is a common feature of term SGA and IUGR fetuses despite of the severity criteria for perinatal outcome. Further research is needed to evaluate the potential long-term consequences on their cardiovascular system. PMID- 29190626 TI - SPARCL1, a Novel Prognostic Predictive Factor for GI Malignancies: a Meta Analysis. AB - BACKGROUND/AIMS: Secreted protein acidic and rich in cysteines-like 1 (SPARCL1) is abnormally expressed in gastrointestinal (GI) malignancies. However, the correlation between SPARCL1 expression and the prognosis of patients remains unknown. Therefore, we performed a meta-analysis to investigate the potential value of SPARCL1 as a prognostic predictive marker for GI malignancies. METHODS: The PubMed, Embase, EBSCO, CNKI, and Wanfang databases were systematically searched for studies examining SPARCL1 and clinicopathological features, including the prognoses of patients. Hazard ratios (HRs) and odds ratios (ORs) from individual studies were calculated and pooled using a random-effects or fix effects model. Heterogeneity and publication bias analyses were performed. RESULTS: Data from 8 studies, including a total of 2,356 patients, were summarized. The expression of SPARCL1 suggested a better prognosis (HR=0.57, 95% CI: 0.445-0.698, P=0.000) and was associated with clinicopathological features of GI malignancies, including distant metastasis (OR=0.44, 95% CI: 0.23-0.85, P=0.014), lymph node metastasis (OR=0.56, 95% CI: 0.39-0.81, P=0.002) and tumor differentiation (OR=2.21, 95% CI: 1.82-2.69, P=0.000). Subgroup analyses based on cancer type revealed that the expression of SPARCL1 had no effect on lymph node metastasis in colorectal cancer, and it did not influence tumor differentiation in gastric cancer. Egger's test showed no evidence of publication bias (all P>0.05). CONCLUSION: SPARCL1 could be a novel prognostic predictive factor for GI malignancies. The expression of SPARCL1 could influence the clinicopathological features of GI malignancies. Further large-scale studies are essential to confirm SPARCL1's prognostic predictive value, and more fundamental experimental studies are needed to illustrate the mechanisms. PMID- 29190625 TI - mTOR as Regulator of Lifespan, Aging, and Cellular Senescence: A Mini-Review. AB - The mechanistic target of rapamycin (mTOR) network is an evolutionary conserved signaling hub that senses and integrates environmental and intracellular nutrient and growth factor signals to coordinate basic cellular and organismal responses such as cell growth, proliferation, apoptosis, and inflammation depending on the individual cell and tissue. A growing list of evidence suggests that mTOR signaling influences longevity and aging. Inhibition of the mTOR complex 1 (mTORC1) with rapamycin is currently the only known pharmacological treatment that increases lifespan in all model organisms studied. This review discusses the potential mechanisms how mTOR signaling controls lifespan and influences aging related processes such as cellular senescence, metabolism, and stem cell function. Understanding these processes might provide novel therapeutic approaches to influence longevity and aging-related diseases. PMID- 29190634 TI - Focal Segmental Glomerulosclerosis Associated with Chronic Progressive External Ophthalmoplegia and Mitochondrial DNA A3243G Mutation. AB - Focal segmental glomerulosclerosis (FSGS) is caused by various etiologies, with mitochondrial dysfunction being one of the causes. FSGS is known to be associated with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS), which is a subclass of mitochondrial disease. However, it has rarely been reported in other mitochondrial disease subclasses. Here, we reported a 20 year-old man diagnosed with FSGS associated with chronic progressive external ophthalmoplegia (CPEO) due to mitochondrial DNA (mtDNA) 3243A>G mutation. He presented with left ptosis, short stature, mild sensorineural deafness, and cardiac conduction block. A renal biopsy sample showed segmental sclerosis and adhesions between capillaries and Bowman's capsule, indicating FSGS. Electron microscopy demonstrated abnormal aggregated mitochondria in podocytes, and the basement membrane and epithelial cells of Bowman's capsule. Skeletal muscle biopsy also showed accumulation of abnormal mitochondria. mtDNA analysis identified heteroplasmic mtDNA 3243A>G mutation with no large-scale deletions. From these findings, we diagnosed the case as CPEO with multi-organ involvement including FSGS. Our report demonstrates that CPEO, as well as MELAS, can be associated with FSGS. Because mitochondrial disease presents with a variety of clinical symptoms, atypical cases with non-classical manifestations are observed. Thus, mitochondrial disease should be considered as an underlying cause of FSGS with systemic manifestations even with atypical phenotypes. PMID- 29190638 TI - Linking gene dynamics to vascular hyperplasia - Toward a predictive model of vein graft adaptation. AB - Reductionist approaches, where individual pieces of a process are examined in isolation, have been the mainstay of biomedical research. While these methods are effective in highly compartmentalized systems, they fail to account for the inherent plasticity and non-linearity within the signaling structure. In the current manuscript, we present the computational architecture for tracking an acute perturbation in a biologic system through a multiscale model that links gene dynamics to cell kinetics, with the overall goal of predicting tissue adaptation. Given the complexity of the genome, the problem is made tractable by clustering temporal changes in gene expression into unique patterns. These cluster elements form the core of an integrated network that serves as the driving force for the response of the biologic system. This modeling approach is illustrated using the clinical scenario of vein bypass graft adaptation. Vein segments placed in the arterial circulation for treatment of advanced occlusive disease can develop an aggressive hyperplastic response that narrows the lumen, reduces blood flow, and induces in situ thrombosis. Reducing this hyperplastic response has been a long-standing but unrealized goal of biologic researchers in the field. With repeated failures of single target therapies, the redundant response pathways are thought to be a fundamental issue preventing progress towards a solution. Using the current framework, we demonstrate how theoretical genomic manipulations can be introduced into the system to shift the adaptation to a more beneficial phenotype, where the hyperplastic response is mitigated and the risk of thrombosis reduced. Utilizing our previously published rabbit vein graft genomic data, where grafts were harvested at time points ranging from 2 hours to 28 days and under differential flow conditions, and a customized clustering algorithm, five gene clusters that differentiated the low flow (i.e., pro-hyperplastic) from high flow (i.e., anti-hyperplastic) response were identified. The current analysis advances these general associations to create a model that identifies those genes sets most likely to be of therapeutic benefit. Using this approach, we examine the range of potential opportunities for intervention via gene cluster over-expression or inhibition, delivered in isolation or combination, at the time of vein graft implantation. PMID- 29190633 TI - Contractile Responses in Spontaneously Hypertensive Rats after Transient Middle Cerebral Artery Occlusion. AB - Stroke is one of the leading causes of mortality and morbidity worldwide, and few therapeutic treatments have shown beneficial effect clinically. One reason for this could be the lack of risk factors incorporated into the preclinical stroke research. We have previously demonstrated phenotypic receptor changes to be one of the injurious mechanisms occurring after stroke but mostly in healthy rats. The aim of this study was to investigate if hypertension has an effect on vasoconstrictive receptor responses to endothelin 1, sarafotoxin 6c and angiotensin II after stroke by inducing transient middle cerebral artery occlusion in spontaneously hypertensive rats and Wistar-Kyoto rats using the wire myograph. We demonstrated an increased contractile response to endothelin 1 and extracellular potassium as well as an increased carbachol-induced dilator response in the middle cerebral arteries from hypertensive rats after stroke. This study demonstrates the importance of including risk factors in experimental stroke research. PMID- 29190630 TI - Alpha-Mangostin Suppresses the Metastasis of Human Renal Carcinoma Cells by Targeting MEK/ERK Expression and MMP-9 Transcription Activity. AB - BACKGROUND/AIMS: alpha-mangostin has anti-carcinogenic effects against several cancers. We investigated the molecular mechanism of this compound on the metastasis of human renal carcinoma cells. METHODS: Cell viability was measured using the MTT assay, and cell cycle distribution using flow cytometry. A Matrigel based assay was used to measure in vitro cell migration and invasion. MAPK related proteins and matrix metalloproteinase (MMP)-9 and MMP-2 expression were measured by western blotting, and MMP2/-9 activities were determined by gelatin zymography. RT-qPCR and a luciferase assay were used to examine the transcriptional activity of MMP-9. RESULTS: alpha-mangostin inhibited the migration and invasion of RCC cells in a dose-dependent manner, but had no evident cytotoxic effects. Treatment of 786-O cells with alpha-mangostin inhibited activation of MEK and ERK. Treatment with a specific MEK inhibitor (U0126) enhanced the inhibitory effects of alpha-mangostin on cell migration and invasion, and the phosphorylation of ERK and MEK. Moreover, alpha-mangostin inhibited the expression of the MMP-9 mRNA levels as well as the activity of MMP 9 promoter, and these suppressive effects were further enhanced by U0126. CONCLUSIONS: Our results suggest that alpha-mangostin suppresses cell migration and invasion via MEK/ERK/MMP9 pathway, and might be a promising anti-metastatic agent against human renal cell carcinoma. PMID- 29190637 TI - Standard-dose osimertinib for refractory leptomeningeal metastases in T790M positive EGFR-mutant non-small cell lung cancer. AB - BACKGROUND: Osimertinib demonstrated promising efficacy for refractory leptomeningeal metastases (LM) in preclinical data and a clinical study at 160 mg, but there is limited data for the standard 80 mg dose. METHODS: T790M positive patients with suspected LM after classical epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) failure were enroled. RESULTS: We investigated 13 patients (5 definitive and 8 possible LM cases). In two of the five definitive cases with T790M in and outside the central nervous system (CNS), osimertinib was effective for both lesions, with cerebrospinal fluid (CSF) clearance of cancer cells and sensitive/T790M mutations. In three definitive cases with extra-CNS T790M without CSF T790M, cancer cells and sensitive mutations in the CSF persisted after osimertinib initiation. The median progression-free survival of all 13 patients was 7.2 months. Osimertinib was generally well-tolerated despite poor performance status, but interstitial lung disease (grade 2) was confirmed in one patient. Based on 25 samples from 13 patients, the osimertinib CSF penetration rate was 2.5+/-0.3%. CONCLUSIONS: Osimertinib 80 mg is a useful therapeutic option for refractory LM after classical EGFR-TKI failure. It appears more effective in CSF T790M-positive cases. PMID- 29190636 TI - Tumour budding in oral squamous cell carcinoma: a meta-analysis. AB - BACKGROUND: Tumour budding has been reported as a promising prognostic marker in many cancers. This meta-analysis assessed the prognostic value of tumour budding in oral squamous cell carcinoma (OSCC). METHODS: We searched OvidMedline, PubMed, Scopus and Web of Science for articles that studied tumour budding in OSCC. We used reporting recommendations for tumour marker (REMARK) criteria to evaluate the quality of studies eligible for meta-analysis. RESULTS: A total of 16 studies evaluated the prognostic value of tumour budding in OSCC. The meta-analysis showed that tumour budding was significantly associated with lymph node metastasis (odds ratio=7.08, 95% CI=1.75-28.73), disease-free survival (hazard ratio=1.83, 95% CI=1.34-2.50) and overall survival (hazard ratio=1.88, 95% CI=1.25-2.82). CONCLUSIONS: Tumour budding is a simple and reliable prognostic marker for OSCC. Evaluation of tumour budding could facilitate personalised management of OSCC. PMID- 29190644 TI - Structural analysis of human glycoprotein butyrylcholinesterase using atomistic molecular dynamics: The importance of glycosylation site ASN241. AB - Human butyrylcholinesterase (BChE) is a glycoprotein capable of bioscavenging toxic compounds such as organophosphorus (OP) nerve agents. For commercial production of BChE, it is practical to synthesize BChE in non-human expression systems, such as plants or animals. However, the glycosylation profile in these systems is significantly different from the human glycosylation profile, which could result in changes in BChE's structure and function. From our investigation, we found that the glycan attached to ASN241 is both structurally and functionally important due to its close proximity to the BChE tetramerization domain and the active site gorge. To investigate the effects of populating glycosylation site ASN241, monomeric human BChE glycoforms were simulated with and without site ASN241 glycosylated. Our simulations indicate that the structure and function of human BChE are significantly affected by the absence of glycan 241. PMID- 29190641 TI - Intracardiac anatomical relationships and potential for streaming in double inlet left ventricles. AB - The aim of this study was to gain better understanding of the variable anatomical features of double inlet left ventricle hearts without cavopulmonary connection that would potentially facilitate favorable streaming. Thirty-nine post-mortem specimens of double inlet left ventricle without cavopulmonary connection were investigated. The focus was on anatomical characteristics that could influence the flow and separation of deoxygenated and oxygenated blood in the ventricles. Elements of interest were the ventriculoarterial connection, the spatial relationship of the ventricles, the position and size of the great arteries, the ventricular septal defect, the presence of relative outflow tract stenosis and the relationship of the inflow and outflow tracts. The most common anatomy was a discordant ventriculoarterial connection with an anatomically left-sided morphologically right ventricle (n = 12, 31%). When looking at the pulmonary trunk/aorta ratio, 21 (72%) hearts showed no pulmonary stenosis relative to the aorta. The ventricular septal defect created a relative subpulmonary or subaortic stenosis in 13 (41%) cases. Sixteen (41%) hearts had a parallel relationship of the inflow and outflow tracts, facilitating separation of deoxygenated and oxygenated blood streams. On the other end of the spectrum were 10 (25%) hearts with a perpendicular relationship, which might lead to maximum mixing of the blood streams. The relationship of the inflow and outflow tracts as well as the presence of (sub-) pulmonary stenosis might play a crucial role in the distribution of blood in double inlet left ventricle hearts. Additional in vivo studies will be necessary to confirm this postulation. PMID- 29190639 TI - Induction of colon and cervical cancer cell death by cinnamic acid derivatives is mediated through the inhibition of Histone Deacetylases (HDAC). AB - Recent studies from our group and many others have shown the ability of histone deacetylase (HDAC) inhibitors for retarding the growth of carcinomas of cervix, colon and rectum in vitro. A search for naturally occurring HDAC inhibitors continues due to the adverse effects associated with known HDAC inhibitors like SAHA and TSA. Therefore in the current study, naturally occurring cinnamic acids derivatives were screened for HDAC inhibitory effect using in silico docking method which identified cinnamic acids as potential candidates. Cinnamic acids (CA) are naturally occurring phenolic compounds known to exhibit anticancer properties. However, it is not clearly known whether the anticancer properties of CA derivatives are due to the inhibition of oncogenic HDACs, if so how the efficacy varies among various CA derivatives. Hence, the HDAC inhibitory potential of CA derivatives containing increasing number of hydroxylic groups or methoxy moieties was determined using Discovery Studio software and the most potent CA derivatives tested ex vivo (biochemical assay) as well as in vitro (using cell based assay). Among CA derivatives tested, dihydroxy cinnamic acid (DHCA, commonly known as caffeic acid) exhibited better interactions with HDAC2 (compared to other isoforms) in silico and inhibited its activity ex vivo as well as in vitro. Targeted reduction of HDAC activity using DHCA induced death of cancer cells by (a) generating reactive oxygen species, (b) arresting cells in S and G2/M phases; and (c) induction of caspase-3 mediated apoptosis. In conclusion, we demonstrated that DHCA inhibited cancer cell growth by binding to HDAC followed by the induction of apoptosis. PMID- 29190642 TI - Measuring stigma affecting sex workers (SW) and men who have sex with men (MSM): A systematic review. AB - BACKGROUND: Stigma involves discrediting a person or group based on a perceived attribute, behaviour or reputation associated with them. Sex workers (SW) and men who have sex with men (MSM) are key populations who are often at increased risk for the acquisition and transmission of HIV and who are affected by stigma that can negatively impact their health and well-being. Although stigma was included as an indicator in the US National HIV/AIDS Strategic Plan and there have been consultations focused on adding a stigma indicator within PEPFAR and the Global Fund in relation to potentiating HIV risks among key populations, there remains limited consensus on the appropriate measurement of SW- or MSM-associated stigma. Consequently, this systematic review summarizes studies using quantitative, qualitative, or mixed methods approaches to measure stigma affecting sex workers and men who have sex with men. METHODS AND FINDINGS: This systematic review included English, French, and Spanish peer-reviewed research of any study design measuring SW- or MSM-associated stigma. Articles were published from January 1, 2004 to March 26, 2014 in PsycINFO, PubMed, EMBASE, CINAHL Plus, Global Health, and World Health Organization Global Health Library Regional Indexes. Of the 541 articles reviewed, the majority measured stigma toward MSM (over 97%), were conducted in North America, used quantitative methods, and focused on internalized stigma. CONCLUSIONS: With the inclusion of addressing stigma in several domestic and international HIV strategies, there is a need to ensure the use of validated metrics for stigma. The field to date has completed limited measurement of stigma affecting sex workers, and limited measurement of stigma affecting MSM outside of higher income settings. Moving forward requires a concerted effort integrating validated metrics of stigma into health-related surveys and programs for key populations. PMID- 29190640 TI - Perceptual integration rapidly activates dorsal visual pathway to guide local processing in early visual areas. AB - Rapidly grouping local elements into an organized object (i.e., perceptual integration) is a fundamental yet challenging task, especially in noisy contexts. Previous studies demonstrate that ventral visual pathway, which is widely known to mediate object recognition, engages in the process by conveying object-level information processed in high-level areas to modulate low-level sensory areas. Meanwhile, recent evidence suggests that the dorsal visual pathway, which is not typically attributable to object recognition, is also involved in the process. However, the underlying whole-brain fine spatiotemporal neuronal dynamics remains unknown. Here we used magnetoencephalography (MEG) recordings in combination with a temporal response function (TRF) approach to dissociate the time-resolved neuronal response that specifically tracks the perceptual grouping course. We demonstrate that perceptual integration initiates robust and rapid responses along the dorsal visual pathway in a reversed hierarchical manner, faster than the ventral pathway. Specifically, the anterior intraparietal sulcus (IPS) responds first (i.e., within 100 ms), followed by activities backpropagating along the dorsal pathway to early visual areas (EVAs). The IPS activity causally modulates the EVA response, even when the global form information is task irrelevant. The IPS-to-EVA response profile fails to appear when the global form could not be perceived. Our results support the crucial function of the dorsal visual pathway in perceptual integration, by quickly extracting a coarse global template (i.e., an initial object representation) within first 100 ms to guide subsequent local sensory processing so that the ambiguities in the visual inputs can be efficiently resolved. PMID- 29190646 TI - Risk factors for incidental durotomy during posterior open spine surgery for degenerative diseases in adults: A multicenter observational study. AB - Incidental durotomy (ID) is a common intraoperative complication of spine surgery. It can lead to persistent cerebrospinal fluid leakage, which may cause serious complications, including severe headache, pseudomeningocele formation, nerve root entrapment, and intracranial hemorrhage. As a result, it contributes to higher healthcare costs and poor patient outcomes. The purpose of this study was to clarify the independent risk factors that can cause ID during posterior open spine surgery for degenerative diseases in adults. We conducted a prospective multicenter study of adult patients who underwent posterior open spine surgery for degenerative diseases at 10 participating hospitals from July 2010 to June 2013. A total of 4,652 consecutive patients were enrolled. We evaluated potential risk factors, including age, sex, body mass index, American Society of Anesthesiologists physical status classification, the presence of diabetes mellitus, the use of hemodialysis, smoking status, steroid intake, location of the surgery, type of operative procedure, and past surgical history in the operated area. A multivariate logistic regression analysis was performed to identify the risk factors associated with ID. The incidence of ID was 8.2% (380/4,652). Corrective vertebral osteotomy and revision surgery were identified as independent risk factors for ID, while cervical surgery and discectomy were identified as factors that independently protected against ID during posterior open spine surgery for degenerative diseases in adults. Therefore, we identified 2 independent risk factors for and 2 protective factors against ID. These results may contribute to making surgeons aware of the risk factors for ID and can be used to counsel patients on the risks and complications associated with open spine surgery. PMID- 29190649 TI - Effects of Lactobacillus acidophilus on gut microbiota composition in broilers challenged with Clostridium perfringens. AB - This study shows the effects of dietary supplementation with Lactobacillus acidophilus on the gut microbiota of broiler chickens challenged with Clostridium perfringens infection during a 21-day period according to pyrosequencing of the 16S ribosomal RNA gene. In a 2 * 2 factorial arrangement of treatments, 308 1-day old male Arbor Acres broiler chicks were analyzed for the effects of the probiotic (groups without or with L. acidophilus supplementation), pathogen challenge (groups without or with C. perfringens), and the effects of interaction. The infection decreased the number of Observed species, Chao1, and ACE of ileal microbiota and increased Chao1 of cecal microbiota of broilers, whereas L. acidophilus supplementation decreased the Shannon index of the ileal microbiota. Shannon index and Simpson indices were lower in the ileal microbiota than in the cecal microbiota. In the ileal microbiota, the control group had higher relative abundance of Lachnospiraceae and Ruminococcaceae in comparison with the other groups; however, the relative abundance of Gammaproteobacteria was significantly higher in the challenge group than in the other groups. C. perfringens infection tended to increase lactate concentration and decreasedconcentrations of formate, acetate and propionate in the ileum; decreased isobutyrate concentration; and tended to decrease isovalerate concentration in the cecum. Besides, L. acidophilus supplementation increased the concentration of lactate and butyrate and decreased concentrations of formate and propionate in the ileum, and increased concentrations of lactate and valerate in the cecum. In conclusion, C. perfringens infection and/or dietary supplementation with L. acidophilus modulated the relative abundance of some bacteria taxa, and the L. acidophilus supplementation helped to restore the microbial community disrupted by C. perfringens infection. PMID- 29190647 TI - The influence of inherited plumage colour morph on morphometric traits and breeding investment in zebra finches (Taeniopygia guttata). AB - Melanin-based plumage polymorphism occurs in many wild bird populations and has been linked to fitness variation in several species. These fitness differences often arise as a consequence of variation in traits such as behaviour, immune responsiveness, body size and reproductive investment. However, few studies have controlled for genetic differences between colour morphs that could potentially generate artefactual associations between plumage colouration and trait variation. Here, we used zebra finches (Taeniopygia guttata) as a model system in order to evaluate whether life-history traits such as adult body condition and reproductive investment could be influenced by plumage morph. To maximise any potential differences, we selected wild-type and white plumage morphs, which differ maximally in their extent of melanisation, while using a controlled three generation breeding design to homogenise the genetic background. We found that F2 adults with white plumage colouration were on average lighter and had poorer body condition than wild-type F2 birds. However, they appeared to compensate for this by reproducing earlier and producing heavier eggs relative to their own body mass. Our study thus reveals differences in morphological and life history traits that could be relevant to fitness variation, although further studies will be required to evaluate fitness effects under natural conditions as well as to characterise any potential fitness costs of compensatory strategies in white zebra finches. PMID- 29190645 TI - CD105+-mesenchymal stem cells migrate into osteoarthritis joint: An animal model. AB - Mesenchymal stem cells are being the focus of connective tissue technology and regenerative medicine, presenting a good choice cell source for improving old and well recognized techniques of cartilage defect repair. For instance, the autologous chondrocyte transplantation using new concepts of regenerative medicine. The present study investigated the risk of xenogenicity of human synovial membrane-derived MSCs, injected into the monkeys using intravenous and intra-articular administration. The animal models used were adult monkeys Rhesus which had been injured into the left knee to create an Osteoarthritis (OA) animal model. CD105+-MSCs were injected twice into the OA monkeys with an interval of one week between them. The animals were euthanized one month after treatment. Immunohistochemistry analysis of different organs: spleen, heart, fat, liver, gut, pancreas, lung, skeletal muscle and kidney from the animals revealed that CD105+-MSCs migrated towards the injured knee joint. MSCs naive were found statistically significant increased in the injured knee in front of healthy one. CD105+-MSCs were negatives for CD68 and the area where CD105+-MSCs were found presented SDF-1 increased levels in front of healthy knee. We concluded that a characterized MSCs subset could be a safe alternative for cell therapy in clearly localized pathologies. PMID- 29190648 TI - Anterior chamber associated immune deviation used as a neuroprotective strategy in rats with spinal cord injury. AB - The inflammatory response is probably one of the main destructive events occurring after spinal cord injury (SCI). Its progression depends mostly on the autoimmune response developed against neural constituents. Therefore, modulation or inhibition of this self-reactive reaction could help to reduce tissue destruction. Anterior chamber associated immune deviation (ACAID) is a phenomenon that induces immune-tolerance to antigens injected into the eye's anterior chamber, provoking the reduction of such immune response. In the light of this notion, induction of ACAID to neural constituents could be used as a potential prophylactic therapy to promote neuroprotection. In order to evaluate this approach, three experiments were performed. In the first one, the capability to induce ACAID of the spinal cord extract (SCE) and the myelin basic protein (MBP) was evaluated. Using the delayed type hypersensibility assay (DTH) we demonstrated that both, SCE and MBP were capable of inducing ACAID. In the second experiment we evaluated the effect of SCE-induced ACAID on neurological and morphological recovery after SCI. In the results, there was a significant improvement of motor recovery, nociceptive hypersensitivity and motoneuron survival in rats with SCE-induced ACAID. Moreover, ACAID also up-regulated the expression of genes encoding for anti-inflammatory cytokines and FoxP3 but down regulated those for pro-inflamatory cytokines. Finally, in the third experiment, the effect of a more simple and practical strategy was evaluated: MBP-induced ACAID, we also found significant neurological and morphological outcomes. In the present study we demonstrate that the induction of ACAID against neural antigens in rats, promotes neuroprotection after SCI. PMID- 29190643 TI - Transcriptomic analysis of gene expression in mice treated with troxerutin. AB - Troxerutin, a semi-synthetic derivative of the natural bioflavanoid rutin, has been reported to possess many beneficial effects in human bodies, such as vasoprotection, immune support, anti-inflammation and anti-aging. However, the effects of troxerutin on genome-wide transcription in blood cells are still unknown. In order to find out effects of troxerutin on gene transcription, a high throughput RNA sequencing was employed to analysis differential gene expression in blood cells consisting of leucocytes, erythrocytes and platelets isolated from the mice received subcutaneous injection of troxerutin. Transcriptome analysis demonstrated that the expression of only fifteen genes was significantly changed by the treatment with troxerutin, among which 5 genes were up-regulated and 10 genes were down-regulated. Bioinformatic analysis of the fifteen differentially expressed genes was made by utilizing the Gene Ontology (GO), and the differential expression induced by troxerutin was further evaluated by real-time quantitative PCR (Q-PCR). PMID- 29190650 TI - Reduced bone length, growth plate thickness, bone content, and IGF-I as a model for poor growth in the CFTR-deficient rat. AB - BACKGROUND: Reduced growth and osteopenia are common in individuals with cystic fibrosis (CF). Additionally, improved weight and height are associated with better lung function and overall health in the disease. Mechanisms for this reduction in growth are not understood. We utilized a new CFTR knockout rat to evaluate growth in young CF animals, via femur length, microarchitecture of bone and growth plate, as well as serum IGF-I concentrations. METHODS: Femur length was measured in wild-type (WT) and SD-CFTRtm1sage (Cftr-/-) rats, as a surrogate marker for growth. Quantitative bone parameters in Cftr-/- and WT rats were measured by micro computed tomography (micro-CT). Bone histomorphometry and cartilaginous growth plates were analyzed. Serum IGF-I concentrations were also compared. RESULTS: Femur length was reduced in both Cftr-/- male and female rats compared to WT. Multiple parameters of bone microarchitecture (of both trabecular and cortical bone) were adversely affected in Cftr-/- rats. There was a reduction in overall growth plate thichkness in both male and female Cftr-/- rats, as well as hypertrophic zone thickness and mean hypertrophic cell volume in male rats, indicating abnormal growth characteristics at the plate. Serum IGF-I concentrations were severely reduced in Cftr-/- rats compared to WT littermates. CONCLUSIONS: Despite absence of overt lung or pancreatic disease, reduced growth and bone content were readily detected in young Cftr-/- rats. Reduced size of the growth plate and decreased IGF-I concentrations suggest the mechanistic basis for this phenotype. These findings appear to be intrinsic to the CFTR deficient state and independent of significant clinical confounders, providing substantive evidence for the importance of CFTR on maintinaing normal bone growth. PMID- 29190651 TI - APOE allele frequencies in suspected non-amyloid pathophysiology (SNAP) and the prodromal stages of Alzheimer's Disease. AB - Biomarker definitions for preclinical Alzheimer's disease (AD) have identified individuals with neurodegeneration (ND+) without beta-amyloidosis (Abeta-) and labeled them with suspected non-AD pathophysiology (SNAP). We evaluated Apolipoprotein E (APOE) epsilon2 and epsilon4 allele frequencies across biomarker definitions-Abeta-/ND- (n = 268), Abeta+/ND- (n = 236), Abeta-/ND+ or SNAP (n = 78), Abeta+/ND+ (n = 204)-hypothesizing that SNAP would have an APOE profile comparable to Abeta-/ND-. Using AD Neuroimaging Initiative data (n = 786, 72+/-7 years, 48% female), amyloid status (Abeta+ or Abeta-) was defined by cerebrospinal fluid (CSF) Abeta-42 levels, and neurodegeneration status (ND+ or ND-) was defined by hippocampal volume from MRI. Binary logistic regression related biomarker status to APOE epsilon2 and epsilon4 allele carrier status, adjusting for age, sex, education, and cognitive diagnosis. Compared to the biomarker negative (Abeta-/ND-) participants, higher proportions of epsilon4 and lower proportions of epsilon2 carriers were observed among Abeta+/ND- (epsilon4: OR = 6.23, p<0.001; epsilon2: OR = 0.53, p = 0.03) and Abeta+/ND+ participants (epsilon4: OR = 12.07, p<0.001; epsilon2: OR = 0.29, p = 0.004). SNAP participants were statistically comparable to biomarker negative participants (p values>0.30). In supplemental analyses, comparable results were observed when coding SNAP using amyloid imaging and when using CSF tau levels. In contrast to APOE, a polygenic risk score for AD that excluded APOE did not show an association with amyloidosis or neurodegeneration (p-values>0.15), but did show an association with SNAP defined using CSF tau (beta = 0.004, p = 0.02). Thus, in a population with low levels of cerebrovascular disease and a lower prevalence of SNAP than the general population, APOE and known genetic drivers of AD do not appear to contribute to the neurodegeneration observed in SNAP. Additional work in population based samples is needed to better elucidate the genetic contributors to various etiological drivers of SNAP. PMID- 29190652 TI - Range-based volatility, expected stock returns, and the low volatility anomaly. AB - One of the foundations of financial economics is the idea that rational investors will discount stocks with more risk (volatility), which will result in a positive relation between risk and future returns. However, the empirical evidence is mixed when determining how volatility is related to future returns. In this paper, we examine this relation using a range-based measure of volatility, which is shown to be theoretically, numerically, and empirically superior to other measures of volatility. In a variety of tests, we find that range-based volatility is negatively associated with expected stock returns. These results are robust to time-series multifactor models as well as cross-sectional tests. Our findings contribute to the debate about the direction of the relationship between risk and return and confirm the presence of the low volatility anomaly, or the anomalous finding that low volatility stocks outperform high volatility stocks. In other tests, we find that the lower returns associated with range based volatility are driven by stocks with lottery-like characteristics. PMID- 29190653 TI - Novel molecular imaging ligands targeting matrix metalloproteinases 2 and 9 for imaging of unstable atherosclerotic plaques. AB - Molecular imaging of matrix metalloproteinases (MMPs) may allow detection of atherosclerotic lesions vulnerable to rupture. In this study, we develop a novel radiolabelled compound that can target gelatinase MMP subtypes (MMP2/9) with high selectivity and inhibitory potency. Inhibitory potencies of several halogenated analogues of MMP subtype-selective inhibitors (N-benzenesulfonyliminodiacetyl monohydroxamates and N-halophenoxy-benzenesulfonyl iminodiacetyl monohydroxamates) were in the nanomolar range for MMP2/9. The analogue with highest inhibitory potency and selectivity was radiolabelled with [123I], resulting in moderate radiochemical yield, and high radiochemical purity. Biodistribution studies in mice, revealed stabilization in blood 1 hour after intravenous bolus injection. Intravenous infusion of the radioligand and subsequent autoradiography of excised aortas showed tracer uptake in atheroprone mice. Distribution of the radioligand showed co-localization with MMP2/9 immunohistochemical staining. In conclusion, we have developed a novel selective radiolabeled MMP2/9 inhibitor, suitable for single photon emission computed tomography (SPECT) imaging that effectively targets atherosclerotic lesions in mice. PMID- 29190654 TI - Prenatal folic acid use associated with decreased risk of myelomeningocele: A case-control study offers further support for folic acid fortification in Bangladesh. AB - Neural tube defects contribute to severe morbidity and mortality in children and adults; however, they are largely preventable through maternal intake of folic acid before and during early pregnancy. We examined the association between maternal prenatal folic acid supplement intake and risk of myelomeningocele (a severe and common type of neural tube defect) in the offspring. We performed secondary analysis using data from a case-control study conducted at Dhaka Community Hospital, Bangladesh between April and November of 2013. Cases and controls included children with and without myelomeningocele, respectively, and their mothers. Cases were identified from local hospitals and rural health clinics served by Dhaka Community Hospital. Controls were selected from pregnancy registries located in the same region as the cases, and matched (1:1) to cases by age and sex. Myelomeningocele in the offspring was confirmed by a pediatrician with expertise in classifying neural tube defects. Maternal prenatal folic acid supplement intake was the main exposure of interest. We estimated crude and adjusted odds ratios (OR) and 95% confidence intervals (CI) using conditional logistic regression analysis. There were 53 pairs of matched cases and controls in our study. Overall, 51% of case mothers reported using folic acid supplements during pregnancy compared to 72% of control mothers (p = 0.03). Median plasma folate concentrations at the time of study visit were 2.79 ng/mL and 2.86 ng/mL among case and control mothers, respectively (p = 0.85). Maternal prenatal folic acid use significantly decreased the odds of myelomeningocele in the offspring (unadjusted OR = 0.42, 95% CI = 0.18-0.96). The association was slightly attenuated after adjusting for maternal age at the time of pregnancy (adjusted OR = 0.43, 95% CI = 0.18-1.02). Our study confirms the protective association between maternal prenatal folic acid supplement use and myelomeningocele among children born in Bangladesh. Our findings point to an overall low folic acid supplement use and low plasma folate concentrations among women of reproductive age in Bangladesh. Mandatory fortification of staple foods with folic acid can address low folate status among women of child-bearing age, and prevent child morbidity and mortality associated with myelomeningocele in Bangladesh. PMID- 29190655 TI - The effects of a culturally-tailored campaign to increase blood donation knowledge, attitudes and intentions among African migrants in two Australian States: Victoria and South Australia. AB - Research suggests that African migrants are often positively predisposed towards blood donation, but are under-represented in participation. A culturally-tailored intervention targeting the African migrant community in Australia was developed and implemented, to enhance knowledge about blood donation, improve attitudes towards donating, increase intentions to donate blood, and increase the number of new African donors in Australia. Four weeks after a targeted campaign, a survey evaluation process commenced, administered face-to-face by bilingual interviewers from the African community in Melbourne and Adelaide, Australia (community survey). The questionnaires covered demographics, campaign awareness, blood donation knowledge and intentions, medical mistrust and perceived discrimination, and were analysed to evaluate changes in knowledge and intention. Sixty-two percent of survey participants (n = 454) reported being aware of the campaign. With increasing campaign awareness, there was a 0.28 increase in knowledge score (p = .005); previous blood donation was also associated with an increased blood donation knowledge score. Blood donation intention scores were not associated with campaign awareness (p = 0.272), but were associated with previous blood donation behaviour and a positive blood donation attitude score. More positive scores on the blood donation attitude measure were associated with increasing blood donation intentions, self-efficacy and campaign awareness (score increases of 0.27, 0.30 and 0.04, respectively, all p<0.05). Data were collected on the ethnicity of new blood donors in six blood collection centres before and after the intervention, and independent of the intervention evaluation survey. These data were also used to assess behavioural changes and the proportions of donors from different countries before and after the survey. There was no difference in the number of new African migrant donors, before and after the intervention. The culturally-relevant marketing campaign was associated with improved blood donation knowledge and attitudes, but there was no short-term change in blood donation intentions or the number of African donors. PMID- 29190656 TI - MRI for the assessment of malignancy in BI-RADS 4 mammographic microcalcifications. AB - PURPOSE: Assess the performance of breast MRI to diagnose breast cancer in BI RADS 4 microcalcifications detected by mammography. MATERIALS AND METHODS: This retrospective, IRB-approved study included 248 consecutive contrast-enhanced breast MRI (1.5T, protocol in accordance with EUSOBI recommendations) performed to further diagnose BI-RADS 4 microcalcifications detected at mammography during a 3-year period. Standard of reference had to be established by histopathology. Routine consensus reading results by two radiologists were dichotomized as positive or negative and compared with the reference standard (benign vs malignant) to calculate diagnostic parameters. RESULTS: There were 107 malignant and 141 benign microcalcifications. Malignancy rates were 18.3% (23/126 BI-RADS 4a), 41.7% (25/60 BI-RADS 4b) and 95% (59/62 BI-RADS 4c). There were 103 true positive, 116 true-negative, 25 false-positive, and 4 false-negative (one invasive cancer, three DCIS; 2 BI-RADS 4c, 1 BI-RADS 4b on mammography) breast MRI findings, effecting a sensitivity, specificity, PPV, and NPV of 96.3% (95%-CI 90.7-99.0%), 82.3% (95%-CI 75.0-88.2%), 80.5% (95%-CI 72.5-87.0%) and 96.7% (95% CI 91.7-99.1%), respectively. CONCLUSION: MRI is an accurate tool to further diagnose BI-RADS 4a and 4b microcalcifications and may be helpful to avoid unnecessary biopsies in BI-RADS 4a and 4b lesions. BI-RADS 4c microcalcifications should be biopsied irrespective of MRI findings. PMID- 29190657 TI - Tree seedlings respond to both light and soil nutrients in a Patagonian evergreen deciduous forest. AB - Seedlings of co-occurring species vary in their response to resource availability and this has implications for the conservation and management of forests. Differential shade-tolerance is thought to influence seedling performance in mixed Nothofagus betuloides-Nothofagus pumilio forests of Patagonia. However, these species also vary in their soil nutrient requirements. To determine the effects of light and soil nutrient resources on small seedlings we examined responses to an experimental reduction in canopy tree root competition through root trenching and restricting soil nutrient depletion through the addition of fertilizer. To understand the effect of light these treatments were undertaken in small canopy gaps and nearby beneath undisturbed canopy with lower light levels. Seedling diameter growth was greater for N. pumilio and height growth was greater for N. betuloides. Overall, diameter and height growth were greater in canopy gaps than beneath undisturbed canopy. Such growths were also greater with fertilizer and root trenching treatments, even beneath undisturbed canopy. Seedling survival was lower under such treatments, potentially reflecting thinning facilitated by resource induced growth. Finally, above-ground biomass did not vary among species although the less shade tolerant N. pumilio had higher below-ground biomass and root to shoot biomass ratio than the more shade tolerant N. betuloides. Above- and below-ground biomass were higher in canopy gaps so that the root to shoot biomass ratio was similar to that beneath undisturbed canopy. Above-ground biomass was also higher with fertilizer and root trenching treatments and that lowered the root to shoot biomass ratio. Restricting soil nutrient depletion allowed seedlings of both species to focus their responses above-ground. Our results support a view that soil nutrient resources, as well as the more commonly studied light resources, are important to seedlings of Nothofagus species occurring on infertile soils. PMID- 29190658 TI - Screening tools to identify patients with complex health needs at risk of high use of health care services: A scoping review. AB - BACKGROUND: Many people with chronic conditions have complex health needs often due to multiple chronic conditions, psychiatric comorbidities, psychosocial issues, or a combination of these factors. They are at high risk of frequent use of healthcare services. To offer these patients interventions adapted to their needs, it is crucial to be able to identify them early. OBJECTIVE: The aim of this study was to find all existing screening tools that identify patients with complex health needs at risk of frequent use of healthcare services, and to highlight their principal characteristics. Our purpose was to find a short, valid screening tool to identify adult patients of all ages. METHODS: A scoping review was performed on articles published between 1985 and July 2016, retrieved through a comprehensive search of the Scopus and CINAHL databases, following the methodological framework developed by Arksey and O'Malley (2005), and completed by Levac et al. (2010). RESULTS: Of the 3,818 articles identified, 30 were included, presenting 14 different screening tools. Seven tools were self reported. Five targeted adult patients, and nine geriatric patients. Two tools were designed for specific populations. Four can be completed in 15 minutes or less. Most screening tools target elderly persons. The INTERMED self-assessment (IM-SA) targets adults of all ages and can be completed in less than 15 minutes. CONCLUSION: Future research could evaluate its usefulness as a screening tool for identifying patients with complex needs at risk of becoming high users of healthcare services. PMID- 29190659 TI - A digital memories based user authentication scheme with privacy preservation. AB - The traditional username/password or PIN based authentication scheme, which still remains the most popular form of authentication, has been proved insecure, unmemorable and vulnerable to guessing, dictionary attack, key-logger, shoulder surfing and social engineering. Based on this, a large number of new alternative methods have recently been proposed. However, most of them rely on users being able to accurately recall complex and unmemorable information or using extra hardware (such as a USB Key), which makes authentication more difficult and confusing. In this paper, we propose a Digital Memories based user authentication scheme adopting homomorphic encryption and a public key encryption design which can protect users' privacy effectively, prevent tracking and provide multi-level security in an Internet & IoT environment. Also, we prove the superior reliability and security of our scheme compared to other schemes and present a performance analysis and promising evaluation results. PMID- 29190660 TI - Actionable mutations in canine hemangiosarcoma. AB - BACKGROUND: Angiosarcomas (AS) are rare in humans, but they are a deadly subtype of soft tissue sarcoma. Discovery sequencing in AS, especially the visceral form, is hampered by the rarity of cases. Most diagnostic material exists as archival formalin fixed, paraffin embedded tissue which serves as a poor source of high quality DNA for genome-wide sequencing. We approached this problem through comparative genomics. We hypothesized that exome sequencing a histologically similar tumor, hemangiosarcoma (HSA), that occurs in approximately 50,000 dogs per year, may lead to the identification of potential oncogenic drivers and druggable targets that could also occur in angiosarcoma. METHODS: Splenic hemangiosarcomas are common in dogs, which allowed us to collect a cohort of archived matched tumor and normal tissue samples suitable for whole exome sequencing. Mapping of the reads to the latest canine reference genome (Canfam3) demonstrated that >99% of the targeted exomal regions were covered, with >80% at 20X coverage and >90% at 10X coverage. RESULTS AND CONCLUSIONS: Sequence analysis of 20 samples identified somatic mutations in PIK3CA, TP53, PTEN, and PLCG1, all of which correspond to well-known tumor drivers in human cancer, in more than half of the cases. In one case, we identified a mutation in PLCG1 identical to a mutation observed previously in this gene in human visceral AS. Activating PIK3CA mutations present novel therapeutic targets, and clinical trials of targeted inhibitors are underway in human cancers. Our results lay a foundation for similar clinical trials in canine HSA, enabling a precision medicine approach to this disease. PMID- 29190661 TI - Physiological effects of a novel artificially synthesized antimalarial cyclic peptide: Mahafacyclin B. AB - Mahafacyclin B is a cyclic peptide isolated from the latex of Jatropha mahafalensis and is an antimalarial agent. However, the physiological effects of mahafacyclin B in mammalian cells are not known. Here, we assessed the growth, morphology, and alterations in the transcriptome of CHO-K1 cells exposed to mahafacyclin B (0-22 MUM). Mahafacyclin B at 2.2 MUM did not affect the proliferation or death of CHO-K1 cells. Mahafacyclin B was not toxic to mammalian cells at 2.2 MUM, which represents a normal physiological concentration at which mahafacyclin B retains its antimalarial properties. Interestingly, mahafacyclin B altered the size and morphology of CHO-K1 cells. Comparative transcriptomics revealed that mahafacyclin B modulated the expression of a specific subset of genes. PMID- 29190662 TI - Using systems science to understand the determinants of inequities in healthy eating. AB - INTRODUCTION: Systems thinking has emerged in recent years as a promising approach to understanding and acting on the prevention and amelioration of non communicable disease. However, the evidence on inequities in non-communicable diseases and their risks factors, particularly diet, has not been examined from a systems perspective. We report on an approach to developing a system oriented policy actor perspective on the multiple causes of inequities in healthy eating. METHODS: Collaborative conceptual modelling workshops were held in 2015 with an expert group of representatives from government, non-government health organisations and academia in Australia. The expert group built a systems model using a system dynamics theoretical perspective. The model developed from individual mind maps to pair blended maps, before being finalised as a causal loop diagram. RESULTS: The work of the expert stakeholders generated a comprehensive causal loop diagram of the determinants of inequity in healthy eating (the HE2 Diagram). This complex dynamic system has seven sub-systems: (1) food supply and environment; (2) transport; (3) housing and the built environment; (4) employment; (5) social protection; (6) health literacy; and (7) food preferences. DISCUSSION: The HE2 causal loop diagram illustrates the complexity of determinants of inequities in healthy eating. This approach, both the process of construction and the final visualisation, can provide the basis for planning the prevention and amelioration of inequities in healthy eating that engages with multiple levels of causes and existing policies and programs. PMID- 29190663 TI - Self-microemulsifying drug delivery system and nanoemulsion for enhancing aqueous miscibility of Alpinia galanga oil. AB - Alpinia galanga oil (AGO) possesses various activities but low aqueous solubility limits its application particularly in aquatic animals. AGO has powerful activity on fish anesthesia. Ethanol used for enhancing water miscible of AGO always shows severe side effects on fish. The present study explores the development of self microemulsifying drug delivery systems (SMEDDS) and nanoemulsions (NE) to deliver AGO for fish anesthesia with less or no alcohol. Pseudoternary phase diagrams were constructed to identify the best SMEDDS-AGO formulation, whereas NE-AGO were developed by means of high-energy emulsification. The mean droplet size of the best SMEDDS-AGO was 82 +/- 0.5 nm whereas that of NE-AGO was 48 +/- 1.6 nm. The anesthetic effect of the developed SMEDDS-AGO and NE-AGO in koi (Cyprinus carpio) was evaluated and compared with AGO ethanolic solution (EtOH-AGO). It was found that the time of induction the fish to reach the surgical stage of anesthesia was dose dependent. NE-AGO showed significantly higher activity than SMEDDS-AGO and EtOH-AGO, respectively. EtOH-AGO caused unwanted hyperactivity in the fish. This side effect did not occur in the fish anesthetized with SMEDDS-AGO and NE-AGO. In conclusion, SMEDDS and NE are promising delivery systems for AGO. PMID- 29190664 TI - A systematic review of zoonotic enteric parasitic diseases among nomadic and pastoral people. AB - INTRODUCTION: Zoonotic enteric parasites are ubiquitous and remain a public health threat to humans due to our close relationship with domestic animals and wildlife, inadequate water, sanitation, and hygiene practices and diet. While most communities are now sedentary, nomadic and pastoral populations still exist and experience unique exposure risks for acquiring zoonotic enteric parasites. Through this systematic review we sought to summarize published research regarding pathogens present in nomadic populations and to identify the risk factors for their infection. METHODS: Using systematic review guidelines set forth by PRISMA, research articles were identified, screened and summarized based on exclusion criteria for the documented presence of zoonotic enteric parasites within nomadic or pastoral human populations. A total of 54 articles published between 1956 and 2016 were reviewed to determine the pathogens and exposure risks associated with the global transhumance lifestyle. RESULTS: The included articles reported more than twenty different zoonotic enteric parasite species and illustrated several risk factors for nomadic and pastoralist populations to acquire infection including; a) animal contact, b) food preparation and diet, and c) household characteristics. The most common parasite studied was Echinococcosis spp. and contact with dogs was recognized as a leading risk factor for zoonotic enteric parasites followed by contact with livestock and/or wildlife, water, sanitation, and hygiene barriers, home slaughter of animals, environmental water exposures, household member age and sex, and consumption of unwashed produce or raw, unprocessed, or undercooked milk or meat. CONCLUSION: Nomadic and pastoral communities are at risk of infection with a variety of zoonotic enteric parasites due to their living environment, cultural and dietary traditions, and close relationship to animals. Global health efforts aimed at reducing the transmission of these animal-to-human pathogens must incorporate a One Health approach to support water, sanitation, and hygiene development, provide education on safe food handling and preparation, and improve the health of domestic animals associated with these groups, particularly dogs. PMID- 29190665 TI - Distinctness of Brazilian common bean cultivars with carioca and black grain by means of morphoagronomic and molecular descriptors. AB - Common bean (Phaseolus vulgaris L.) is one of the most important legumes for human consumption and is a staple food in the diet of the population of some countries of Latin America, Africa and Asia. The distinction between cultivars is based predominantly on morphological descriptors, which proved inefficient for the differentiation of some cultivars. This study had the objective of describing, distinguishing and evaluating the agronomic potential of 39 common bean cultivars of the carioca and black grain groups registered for cultivation in Brazil, based on 49 morphoagronomic descriptors and microsatellite (simple sequence repeat -SSR) markers. The morphoagronomic traits of each commercial group were characterized in four environments. Thirty-seven SSR markers were used for the molecular description. The morphological data, analyzed by the Shanonon Weaver index, detected low variability among cultivars for qualitative data. On the other hand, the estimates of variance analysis, relative importance of the traits and hierarchical grouping analysis applied to the quantitative variables showed that the descriptors related to plant morphology were the most important for the carioca group, and those related to seed morphology were determining for the black group. The genetic parameters estimated for SSR markers by hierarchical and Bayesian cluster analysis identified 116 alleles, with 33 and 30 polymorphic loci and 24 and 22 private alleles for the carioca and black groups, respectively. The combined use of morphoagronomic and molecular descriptors improves the distinguishability of cultivars, contributing in a more efficient way to breeding and to the protection of cultivars. PMID- 29190666 TI - Movement to outpatient hysterectomy for benign indications in the United States, 2008-2014. AB - INTRODUCTION: The past decade has witnessed adoption of conservative gynecologic treatments, including minimally invasive surgery (MIS), alongside steady declines in inpatient hysterectomies. It remains unclear what factors have contributed to trends in outpatient benign hysterectomy (BH), as well as whether these trends exacerbate disparities. MATERIALS AND METHODS: Retrospective cohort of 527,964 women >=18 years old who underwent BH from 2008 to 2014. BH surgical approaches included: open/abdominal hysterectomy (AH), vaginal hysterectomy (VH), laparoscopic hysterectomy (LH), and robotic-assisted hysterectomy (RH). Quarterly frequencies were calculated by care setting and surgical approach. We used multilevel logistic regression (MLR) using the most recent year of data (2014) to examine the influence of patient-, physician-, and hospital-level preoperative factors and surgical approaches on outpatient migration. RESULTS: From 2008-2014, surgical approaches for LH and RH increased, which coincided with decreases in VH and AH. Overall, a 44.2% shift was observed from inpatient to outpatient settings (P<0.0001). Among all outpatient visits MIS increased, particularly for RH (3.6% to 41.07%). We observed increases in the proportion of non-Hispanic Black and Medicaid patients who obtained MIS in 2014 vs. 2008 (P<0.001). Surgical approach (51.8%) and physician outpatient MIS experience (19.9%) had the greatest influence on predicting outpatient BH. Compared with LH, RH was associated with statistically significantly higher likelihood of outpatient BH overall (OR 1.23; 95% CI, 1.16-1.31), as well as in sub-analyses of more complex cases and hospitals that performed >=1 RH (P<0.05). CONCLUSION: From 2008-2014, rates of LH and RH significantly increased. A significant shift from inpatient to outpatient setting was observed. These findings suggest that RH may facilitate the shift to outpatient BH, particularly for patients with complexities. The adoption of MIS in outpatient settings may improve access to disadvantaged patient groups. PMID- 29190667 TI - Hospital admissions for skin infections among Western Australian children and adolescents from 1996 to 2012. AB - The objective of this study was to describe the occurrence of skin infection associated hospitalizations in children born in Western Australia (WA). We conducted a retrospective cohort study of all children born in WA between 1996 and 2012 (n = 469,589). Of these, 31,348 (6.7%) were Aboriginal and 240,237 (51.2%) were boys. We report the annual age-specific hospital admission rates by geographical location and diagnostic category. We applied log-linear regression modelling to analyse changes in temporal trends of hospitalizations. Hospitalization rates for skin infections in Aboriginal children (31.7/1000 child years; 95% confidence interval [CI] 31.0-32.4) were 15.0 times higher (95% CI 14.5-15.5; P<0.001) than those of non-Aboriginal children (2.1/1000 child-years; 95% CI 2.0-2.1). Most admissions in Aboriginal children were due to abscess, cellulitis and scabies (84.3%), while impetigo and pyoderma were the predominant causes in non-Aboriginal children (97.7%). Admissions declined with age, with the highest rates for all skin infections observed in infants. Admissions increased with remoteness. Multiple admissions were more common in Aboriginal children. Excess admissions in Aboriginal children were observed during the wet season in the Kimberley and during summer in metropolitan areas. Our study findings show that skin infections are a significant cause of severe disease, requiring hospitalization in Western Australian children, with Aboriginal children at a particularly high risk. Improved community-level prevention of skin infections and the provision of effective primary care are crucial in reducing the burden of skin infection associated hospitalizations. The contribution of sociodemographic and environmental risk factors warrant further investigation.

AB - This paper focuses on the technological characteristics of Keilmesser with a lateral tranchet blow modification on the cutting edge. It examines the underlying technological production of these bifacial objects: this implies the evaluation of their working stage succession, as well as produced forms necessary for the execution of tranchet blow performance. Furthermore, it offers a techno morphological description of these enigmatic tools. The Keilmesser with tranchet blow and corresponding blanks of tranchet blows from Grotte de la Verpilliere I in Germolles (Saone-et-Loire, France) are used as case study. The collection of Keilmesser with tranchet blow and corresponding blanks of tranchet blow has been massively expanded with new fieldwork and the review of ancient assemblages. The majority of the pieces were made on blanks from local raw material. The evaluation of the underlying production concept shows that a Keilmesser with tranchet blow, regardless of the wide range of morphologies and matrix size, always consists of specific parts that are necessary for the production sequence and the assumed function. The production of these pieces follows highly specific working stages, some of which can be interchanged in sequence. However, it is always the goal to obtain a low-angled cutting edge. The performance of a tranchet blow is not only an integral part of production, but it is rather the aim of the entire production.

AB - Although histological grade and muscular invasion are related to the malignant behaviors of endometrial endometrioid carcinoma, lymphatic and/or distant metastases are unexpectedly encountered, even in patients in the low-risk group. To re-evaluate additional reliable parameters to predict the risk of progression, we examined the immunohistochemical expression profiles of p53 and estrogen receptor (ER) beta proteins. Patients with endometrial endometrioid carcinoma who underwent surgical treatment at our hospital (n = 154) were recruited to this study, and the significance of the relationships between the incidence of regional lymph node metastasis and/or postoperative recurrence and clinical or experimental parameters was evaluated. By multivariate analysis, we found that histological grades, detection of immunoreactive p53 (positive rates more than 10%, p53-stained), and high expression of ERbeta (high-ERbeta) were independently associated with metastasis and/or recurrence. Among these parameters, the sensitivity and negative predictive values of high-ERbeta were very high (up to 100%). In the population with high-ERbeta, the positive rates of metastasis and/or recurrence were 61.1% in the p53-stained group and 21.9% in the p53-non stained (negative) group. Furthermore, the positive rate in the group showing myometrial invasion of more than 1/2 and showing both p53-stained and high-ERbeta was 80%. The disease-free survival of patients who were double-positive for p53 stained and high-ERbeta was significantly shorter than that in other patients. In summary, our findings showed that increases in ERbeta and p53 immunoreactivity were significantly correlated with the incidence of metastasis and/or recurrence in endometrial endometrioid carcinoma, suggesting that double-positivity for p53 stained and high-ERbeta may provide a promising clinical indicator to predict the risk of progression. PMID- 29190670 TI - Quantification of HBsAg to predict low levels and seroclearance in HBeAg-negative patients receiving nucleos(t)ide analogues. AB - BACKGROUND: HBeAg-negative chronic hepatitis B patients require long-term nucleos(t)ide analogues(NAs) because loss of surface antigen (HBsAg) is unusual. Low quantitative HBsAg (qHBsAg) levels can identify patients with higher probability of seroclearance. The aim of our study was to evaluate qHBsAg in HBeAg-negative patients receiving NAs to predict a reduction of HBsAg levels and seroclearance. METHODS: Retrospective analysis of qHBsAg in HBeAg-negative patients before and at years 1, 3, 5, 8 and over of NAs treatment. RESULTS: From 1999 to 2015, HBsAg was quantified in 358 serum samples from 95 HBeAg-negative patients. Low qHBsAg (<120 IU/mL) was identified at baseline or during follow-up in 14% of patients and HBsAg loss in 4%. No baseline variables predicted seroclearance and only treatment duration predicted low qHBsAg. The annual decline of qHBsAg was -0.102 log IU/mL and the median time to HBsAg loss was 6.04 years. The decline was greater in patients achieving low HBsAg levels (-0.257) than in those who did not (-0.057)(p<0.001). The diagnostic accuracy (ROC curve, 95%CI) of qHBsAg delta at year 3 was 0.89 (0.81-0.97), with cut-off >0.3 log IU/mL showing a positive and negative predictive value of 42% and 100% to identify patients achieving low levels of HBsAg. CONCLUSIONS: Reduction of qHBsAg is slow in HBeAg-negative patients receiving NAs, although low levels or faster qHBsAg decline may occur in 14%. A qHBsAg reduction >0.3 log IU/mL at year 3 can identify patients with a higher probability of achieving low levels and HBsAg seroclearance. PMID- 29190671 TI - malERA: An updated research agenda for insecticide and drug resistance in malaria elimination and eradication. AB - Resistance to first-line treatments for Plasmodium falciparum malaria and the insecticides used for Anopheles vector control are threatening malaria elimination efforts. Suboptimal responses to drugs and insecticides are both spreading geographically and emerging independently and are being seen at increasing intensities. Whilst resistance is unavoidable, its effects can be mitigated through resistance management practices, such as exposing the parasite or vector to more than one selective agent. Resistance contributed to the failure of the 20th century Global Malaria Eradication Programme, and yet the global response to this issue continues to be slow and poorly coordinated-too often, too little, too late. The Malaria Eradication Research Agenda (malERA) Refresh process convened a panel on resistance of both insecticides and antimalarial drugs. This paper outlines developments in the field over the past 5 years, highlights gaps in knowledge, and proposes a research agenda focused on managing resistance. A deeper understanding of the complex biological processes involved and how resistance is selected is needed, together with evidence of its public health impact. Resistance management will require improved use of entomological and parasitological data in decision making, and optimisation of the useful life of new and existing products through careful implementation, combination, and evaluation. A proactive, collaborative approach is needed from basic science and the development of new tools to programme and policy interventions that will ensure that the armamentarium of drugs and insecticides is sufficient to deal with the challenges of malaria control and its elimination. PMID- 29190674 TI - A Bayesian view of murine seminal cytokine networks. AB - It has long been established that active agents in seminal fluid are key to initiating and coordinating mating-induced immunomodulation. This is in part governed by the actions of a network of cytokine interactions which, to date, remain largely undefined, and whose interspecific evolutionary conservation is unknown. This study applied Bayesian methods to illustrate the interrelationships between seminal profiles of interleukin (IL)-1alpha, IL-1beta, IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-12 (p70), IL-13, IL-17, eotaxin, granulocyte-colony stimulating factor (G-CSF), granulocyte macrophage-colony stimulating factor (GM CSF), interferon (IFN)-gamma, keratinocyte-derived chemokine (KC), monocyte chemoattractant protein (MCP-1), macrophage inflammatory protein (MIP-1) alpha, MIP-1beta, regulated on activation normal T cell expressed and secreted (RANTES), tumour necrosis factor (TNF)-alpha, leptin, inducible protein (IP)-10 and vascular endothelial growth factor (VEGF) in a rat model. IL-2, IL-9, IL-12 (p70), IL-13, IL-18, eotaxin, IFN-gamma, IP-10, KC, leptin, MCP-1, MIP-1alpha and TNF-alpha were significantly higher in serum, whilst IL-1beta, IL-5, IL-6, IL-10, IL-17, G-CSF and GM-CSF were significantly higher in seminal fluid. When compared to mouse profiles, only G-CSF was present at significantly higher levels in the seminal fluid in both species. Bayesian modelling highlighted key shared features across mouse and rat networks, namely TNF-alpha as the terminal node in both serum and seminal plasma, and MCP-1 as a central coordinator of seminal cytokine networks through the intermediary of KC and RANTES. These findings reveal a marked interspecific conservation of seminal cytokine networks. PMID- 29190673 TI - Campylobacter jejuni transcriptome changes during loss of culturability in water. AB - BACKGROUND: Water serves as a potential reservoir for Campylobacter, the leading cause of bacterial gastroenteritis in humans. However, little is understood about the mechanisms underlying variations in survival characteristics between different strains of C. jejuni in natural environments, including water. RESULTS: We identified three Campylobacter jejuni strains that exhibited variability in their ability to retain culturability after suspension in tap water at two different temperatures (4 degrees C and 25 degrees C). Of the three, strains C. jejuni M1 exhibited the most rapid loss of culturability whilst retaining viability. Using RNAseq transcriptomics, we characterised C. jejuni M1 gene expression in response to suspension in water by analyzing bacterial suspensions recovered immediately after introduction into water (Time 0), and from two sampling time/temperature combinations where considerable loss of culturability was evident, namely (i) after 24 h at 25 degrees C, and (ii) after 72 h at 4 degrees C. Transcript data were compared with a culture-grown control. Some gene expression characteristics were shared amongst the three populations recovered from water, with more genes being up-regulated than down. Many of the up regulated genes were identified in the Time 0 sample, whereas the majority of down-regulated genes occurred in the 25 degrees C (24 h) sample. CONCLUSIONS: Variations in expression were found amongst genes associated with oxygen tolerance, starvation and osmotic stress. However, we also found upregulation of flagellar assembly genes, accompanied by down-regulation of genes involved in chemotaxis. Our data also suggested a switch from secretion via the sec system to via the tat system, and that the quorum sensing gene luxS may be implicated in the survival of strain M1 in water. Variations in gene expression also occurred in accessory genome regions. Our data suggest that despite the loss of culturability, C. jejuni M1 remains viable and adapts via specific changes in gene expression. PMID- 29190672 TI - First-in-human phase I study of ISTH0036, an antisense oligonucleotide selectively targeting transforming growth factor beta 2 (TGF-beta2), in subjects with open-angle glaucoma undergoing glaucoma filtration surgery. AB - PURPOSE: To evaluate the safety and tolerability of intravitreal ISTH0036, an antisense oligonucleotide selectively targeting transforming growth factor beta 2 (TGF-beta2), in patients with primary open angle glaucoma (POAG) undergoing trabeculectomy (TE; glaucoma filtration surgery). METHODS: In this prospective phase I trial glaucoma patients scheduled for TE with mitomycin C (MMC) received a single intravitreal injection of ISTH0036 at the end of surgery in escalating total doses of 6.75 MUg, 22.5 MUg, 67.5 MUg or 225 MUg, resulting in calculated intraocular ISTH0036 concentrations in the vitreous humor of approximately 0.3 MUM, 1 MUM, 3 MUM or 10 MUM after injection, respectively. Outcomes assessed included: type and frequency of adverse events (AEs), intraocular pressure (IOP), numbers of interventions post trabeculectomy, bleb survival, visual acuity, visual field, electroretinogram (ERG), slit lamp biomicroscopy and optic disc assessment. RESULTS: In total, 12 patients were treated in the 4 dose groups. Main ocular AEs observed were corneal erosion, corneal epithelium defect, or too high or too low IOP, among others. No AE was reported to be related to ISTH0036. All other safety-related analyses did not reveal any toxicities of concern, either. The mean medicated preoperative IOP at decision time-point for surgery was 27.3 mmHg +/- 12.6 mmHg (SD). Mean IOP (+/-SD) for dose levels 1, 2, 3, and 4 were at Day 43 9.8 mmHg +/- 1.0 mmHg, 11.3 mmHg +/- 6.7 mmHg, 5.5 mmHg +/- 3.0 mmHg and 7.5 mmHg +/- 2.3 mmHg SD; and at Day 85 9.7 mmHg +/- 3.3 mmHg, 14.2 mmHg +/- 6.5 mmHg, 5.8 mmHg +/- 1.8 mmHg and 7.8 mmHg +/- 0.6 mmHg, respectively. In contrast to IOP values for dose levels 1 and 2, IOP values for dose levels 3 and 4 persistently remained below 10 mmHg throughout the observation period. CONCLUSION: This first-in-human trial demonstrates that intravitreal injection of ISTH0036 at the end of TE is safe. Regarding IOP control, single-dose ISTH0036 administration of 67.5 MUg or 225 MUg at the time of TE resulted in IOP values persistently < 10 mmHg over the three month postoperative observation period. PMID- 29190675 TI - In patients with suspected acute stroke, CT perfusion-based cerebral blood flow maps cannot substitute for DWI in measuring the ischemic core. AB - BACKGROUND: Neuroimaging may guide acute stroke treatment by measuring the volume of brain tissue in the irreversibly injured "ischemic core." The most widely accepted core volume measurement technique is diffusion-weighted MRI (DWI). However, some claim that measuring regional cerebral blood flow (CBF) with CT perfusion imaging (CTP), and labeling tissue below some threshold as the core, provides equivalent estimates. We tested whether any threshold allows reliable substitution of CBF for DWI. METHODS: 58 patients with suspected stroke underwent DWI and CTP within six hours of symptom onset. A neuroradiologist outlined DWI lesions. In CBF maps, core pixels were defined by thresholds ranging from 0%-100% of normal, in 1% increments. Replicating prior studies, we used receiver operating characteristic (ROC) curves to select thresholds that optimized sensitivity and specificity in predicting DWI-positive pixels, first using only pixels on the side of the brain where infarction was clinically suspected ("unilateral" method), then including both sides ("bilateral"). We quantified each method and threshold's accuracy in estimating DWI volumes, using sums of squared errors (SSE). For the 23 patients with follow-up studies, we assessed whether CBF-derived volumes inaccurately exceeded follow-up infarct volumes. RESULTS: The areas under the ROC curves were 0.89 (unilateral) and 0.90 (bilateral). Various metrics selected optimum CBF thresholds ranging from 29% 32%, with sensitivities of 0.79-0.81, and specificities of 0.83-0.85. However, for the unilateral and bilateral methods respectively, volume estimates derived from all CBF thresholds above 28% and 22% were less accurate than disregarding imaging and presuming every patient's core volume to be zero. The unilateral method with a 30% threshold, which recent clinical trials have employed, produced a mean core overestimation of 65 mL (range: -82-191), and exceeded follow-up volumes for 83% of patients, by up to 191 mL. CONCLUSION: CTP-derived CBF maps cannot substitute for DWI in measuring the ischemic core. PMID- 29190676 TI - Effects of serum 25-hydroxyvitaminD level on decreased bone mineral density at femoral neck and total hip in Chinese type 2 diabetes. AB - OBJECTIVE: The aims of this study is to observe the levels of serum 25 hydroxyvitaminD (25OHD), parathyroid hormone and bone mineral density (BMD) in type 2 diabetes as well as to analyze the correlationship between 25OHD level and BMD. METHODS: The subjects included 368 type 2 diabetic patients, ages ranged 40 79 years and 300 non-diabetic control subjects matched for age, gender and body mass index. The serum 25OHD concentration, parathyroid hormone level and BMDs value at lumbar spine (L1-L4), femoral neck, total hip and total body were measured. The BMDs (g/cm2) was measured by LUNAR's DEXA dual-energy X-ray absorptiometry. RESULTS: 1Compared with control subjects, the serum 25OHD level, BMDs at the femoral neck and total hip declined in type 2 diabetes[(45+/-17 vs. 36+/-12 nmol/L), (0.93+/-0.17 vs. 0.85+/-0.14 g/cm2), (0.93+/-0.14 vs. 0.87+/ 0.15g/cm2) (all P<0.05)]; The parathyroid hormone level in type 2 diabetes was higher in type 2 diabetes than that in control subjects (8.5+/-4.2 vs. 5.6+/-3.9 pmol/L) (P<0.05). 2Compared with diabetes duration <=10 years group, BMDs at the femoral neck and total hip decreased in diabetes duration >10years group [(0.88+/ 0.11 vs. 0.81+/-0.15 g/cm2), (0.91+/-0.14 vs. 0.84+/-0.16 g/cm2)(All P<0.05)]; The parathyroid hormone level increased in diabetes duration >10years group than diabetes duration <=10 years group (10.6+/-9.1 vs. 7.1+/-3.7 pmol/L) (P<0.05). 3 Compared with hemoglobin A1c (HbA1c) <=8% group, 25OHD and BMDs at the femoral neck and total hip in HbA1c>8% group decreased [(40+/-15 vs. 32+/-13 nmol/l), (0.89+/-0.13 vs. 0.83+/-0.13 g/cm2), (0.95+/-0.13 vs. 0.83+/-0.16 g/cm2) (All P<0.05)] and the parathyroid hormone level increased (7.2+/-4.0 vs. 10.0+/-8.8 pmol/L) (P<0.05). 4The morbidity of diabetic osteoporosis and osteopenia (41.0%, 47.8%) were higher than those in control subjects (27.0%,33.3%) (X2 = 4.37 and 4.70, P = 0.04 and 0.03); Diabetes duration, HbA1c and parathyroid hormone levels were longer or higher in Diabetic osteoporosis group than those in normal BMD group and osteopenia group(All p<0.05). 5 Simple factor correlation analysis showed that the BMD at the femoral neck was negatively correlated with the age, diabetes duration, HbA1c, parathyroid hormone (rs = -0.18,-0.23,-0.18,-0.25), and positively correlated with 25OHD (rs = 0.23). CONCLUSIONS: Decreased BMDs and increased incidence of osteoporosis were observed in type 2 diabetic patients, which are closely related to the serum 25OHD level. These findings were more prominent at the femoral neck and total hip for patients with a longer diabetic history and poor glycemic control. PMID- 29190677 TI - Cortical actin nodes: Their dynamics and recruitment of podosomal proteins as revealed by super-resolution and single-molecule microscopy. AB - Electron tomography of the plasma membrane (PM) identified several layers of cortical actin meshwork running parallel to the PM cytoplasmic surface throughout the PM. Here, cortical actin structures and dynamics were examined in living cells, using super-resolution microscopy, with (x,y)- and z-resolutions of ~140 and ~400 nm, respectively, and single-molecule imaging. The super-resolution microscopy identified sub-micron-sized actin clusters that appeared identical by both phalloidin post-fixation staining and Lifeact-mGFP expression followed by fixation, and therefore, these actin clusters were named "actin-pl-clusters". In live cells, the actin-pl-clusters visualized by Lifeact-mGFP linked two or more actin filaments in the fine actin meshwork, acting as a node of the meshwork, and dynamically moved on/along the meshwork in a myosin II-dependent manner. Their formation depended on the Arp2/3 activities, suggesting that the movements could involve both the myosin motor activity and actin polymerization-depolymerization. The actin-pl-clusters differ from the actin nodes/asters found previously after latrunculin treatments, since myosin II and filamin A were not colocalized with the actin-pl-clusters, and the actin-pl-clusters were much smaller than the previously reported nodes/asters. The Lifeact linked to a fluorescently-labeled transmembrane peptide from syntaxin4 (Lifeact-TM) expressed in the PM exhibited temporary immobilization in the PM regions on which actin-pl-clusters and stress fibers were projected, showing that >=66% of actin-pl-clusters and 89% of stress fibers were located in close proximity (within 3.5 nm) to the PM cytoplasmic surface. Podosome-associated cytoplasmic proteins, Tks4, Tks5, cortactin, and N WASP, were transiently recruited to actin-pl-clusters, and thus, we propose that actin-pl-clusters also represent "actin podosome-like clusters". PMID- 29190678 TI - Type I interferon signaling restrains IL-10R+ colonic macrophages and dendritic cells and leads to more severe Salmonella colitis. AB - Type I interferons (IFNalpha, IFNbeta) are key regulators of innate and adaptive immunity, modulating the severity of both viral and bacterial infections. While type I IFN signaling leads to improved outcomes in viral infections, its role in bacterial infections is more contextual and depends on the specific pathogen and route of infection. Given the limited evidence on whether type I IFN signaling affects enteric bacterial pathogens, we investigated the role of this signaling pathway in Salmonella enterica serovar Typhimurium (S. typhimurium)-induced colitis. Comparing mice deficient in IFNAR1- the common receptor for IFNalpha and IFNbeta- with wild-type mice, we found that type I IFN signaling leads to more rapid death, more severe colonic inflammation, higher serum levels of pro inflammatory cytokines, and greater bacterial dissemination. Specific ablation of plasmacytoid dendritic cells (pDCs), which are prominent producers of type I IFNs in antiviral responses, did not alter survival after infection. This result established that pDCs do not play a major role in the pathogenesis of S. typhimurium colitis. Flow cytometric analysis of macrophages and conventional dendritic cells (cDCs) during active colitis demonstrated an increase in CD11c- macrophages and CD103+ cDCs in the colon of Ifnar1-/- animals. Interestingly, cells expressing the anti-inflammatory cytokine receptor IL-10R are more abundant within these subsets in Ifnar1-/- than in wild-type mice. Moreover, blockade of IL-10R in Ifnar1-/- mice increased their susceptibility to S. typhimurium colitis, suggesting that altered numbers of these immunoregulatory cells may underlie the difference in disease severity. This cross-talk between type I IFN and IL-10R signaling pathways may represent a key host cellular mechanism to investigate further in order to unravel the balance between pathogenic inflammation and homeostasis of the colon. Taken together, our data clearly demonstrate that type I IFN signaling is pathogenic in S. typhimurium colitis. PMID- 29190679 TI - Infarct morphology assessment in patients with carotid artery/middle cerebral artery occlusion using fast fluid-attenuated inversion recovery (FLAIR) vascular hyperintensity (FVH). AB - We aim to evaluate the value of fast fluid-attenuated inversion recovery (FLAIR) vascular hyperintensity (FVH) in assessing infarct morphology in patients with symptomatic internal carotid artery (ICA) or middle cerebral artery (MCA) occlusions. Magnetic resonance (MR) diffusion-weighted imaging (DWI) FLAIR sequences, and carotid/cerebral magnetic resonance angiography of 102 patients with symptomatic ICA or MCA occlusions were evaluated. The location and score of FVH were determined using Olindo's method; patients were classified as having Low or High FVHs based on FVH score, and either Distal or Proximal FVH based on FVH location. The differences between infarct morphologies were analyzed. FVH were detectable in 62 patients with High FVH and in 40 patients with Low FVHs based on the Olindo's scale. There were no statistically significant differences in age, gender, hypertension, diabetes, hyperlipidemia, smoking history, and vascular occlusive site between High and Low FVHs patients, except for infarct morphology (P<0.01). Patients with Distal FVH presented with significant (P<0.01) perforating artery and border zone infarcts, whereas those with Proximal FVH had significant (P<0.01) large territorial infarcts. The scores and locations of FVH could be a predictive imaging marker for infarct morphology in patients with symptomatic ICA or MCA occlusion. PMID- 29190680 TI - Identifying social factors amongst older individuals in linked electronic health records: An assessment in a population based study. AB - Identification and quantification of health inequities amongst specific social groups is a pre-requisite for designing targeted healthcare interventions. This study investigated the recording of social factors in linked electronic health records (EHR) of individuals aged >=65 years, to assess the potential of these data to identify the social determinants of disease burden and uptake of healthcare interventions. Methodology was developed for ascertaining social factors recorded on or before a pre-specified index date (01/01/2013) using primary care data from Clinical Practice Research Datalink (CPRD) linked to hospitalisation and deprivation data in a cross-sectional study. Social factors included: religion, ethnicity, immigration status, small area-level deprivation, place of residence (including communal establishments such as care homes), marital status and living arrangements (e.g. living alone, cohabitation). Each social factor was examined for: completeness of recording including improvements in completeness by using other linked EHR, timeliness of recording for factors that might change over time and their representativeness (compared with English 2011 Census data when available). Data for 591,037 individuals from 389 practices from England were analysed. The completeness of recording varied from 1.6% for immigration status to ~80% for ethnicity. Linkages provided the deprivation data (available for 82% individuals) and improved completeness of ethnicity recording from 55% to 79% (when hospitalisation data were added). Data for ethnicity, deprivation, living arrangements and care home residence were comparable to the Census data. For time-varying variables such as residence and living alone, ~60% and ~35% respectively of those with available data, had this information recorded within the last 5 years of the index date. This work provides methods to identify social factors in EHR relevant to older individuals and shows that factors such as ethnicity, deprivation, not living alone, cohabitation and care home residence can be ascertained using these data. Applying these methodologies to routinely collected data could improve surveillance programmes and allow assessment of health equity in specific healthcare studies.

AB - For urban rail transit network, the space-time flow distribution can play an important role in evaluating and optimizing the space-time resource allocation. For obtaining the space-time flow distribution without the restriction of schedules, a dynamic assignment problem is proposed based on the concept of continuous transmission. To solve the dynamic assignment problem, the cell transmission model is built for urban rail transit networks. The priority principle, queuing process, capacity constraints and congestion effects are considered in the cell transmission mechanism. Then an efficient method is designed to solve the shortest path for an urban rail network, which decreases the computing cost for solving the cell transmission model. The instantaneous dynamic user optimal state can be reached with the method of successive average. Many evaluation indexes of passenger flow can be generated, to provide effective support for the optimization of train schedules and the capacity evaluation for urban rail transit network. Finally, the model and its potential application are demonstrated via two numerical experiments using a small-scale network and the Beijing Metro network. PMID- 29190683 TI - Usability study of pH strips for nasogastric tube placement. AB - AIMS: (1) To model the process of use and usability of pH strips (2) to identify, through simulation studies, the likelihood of misreading pH strips, and to assess professional's acceptance, trust and perceived usability of pH strips. METHODS: This study was undertaken in four phases and used a mixed method approach (an audit, a semi-structured interview, a survey and simulation study). The three months audit was of 24 patients, the semi-structured interview was performed with 19 health professionals and informed the process of use of pH strips. A survey of 134 professionals and novices explored the likelihood of misinterpreting pH strips. Standardised questionnaires were used to assess professionals perceived usability, trust and acceptance of pH strip use in a simulated study. RESULTS: The audit found that in 45.7% of the cases aspiration could not be achieved, and that 54% of the NG-tube insertions required x-ray confirmation. None of those interviewed had received formal training on pH strips use. In the simulated study, participants made up to 11.15% errors in reading the strips with important implications for decision making regarding NG tube placement. No difference was identified between professionals and novices in their likelihood of misinterpreting the pH value of the strips. Whilst the overall experience of usage is poor (47.3%), health professionals gave a positive level of trust in both the interview (62.6%) and the survey (68.7%) and acceptance (interview group 65.1%, survey group 74.7%). They also reported anxiety in the use of strips (interview group 29.7%, survey group 49.7%). CONCLUSIONS: Significant errors occur when using pH strips in a simulated study. Manufacturers should consider developing new pH strips, specifically designed for bedside use, that are more usable and less likely to be misread. PMID- 29190684 TI - Respiratory syncytial and influenza viruses in children under 2 years old with severe acute respiratory infection (SARI) in Maputo, 2015. AB - INTRODUCTION: Although respiratory syncytial virus (RSV) and influenza virus (influenza) infections are one of the leading causes of Severe Acute Respiratory Infections (SARI) and death in young children worldwide, little is known about the burden of these pathogens in Mozambique. MATERIAL AND METHODS: From January 2015 to January 2016, nasopharyngeal swabs from 450 children, aged <=2 years, who had been admitted to the Pediatric Department of the Maputo Central Hospital (HCM) in Mozambique, suffering with SARI were enrolled and tested for influenza and RSV using a real-time PCR assay. RESULTS: Influenza and RSV were detected in 2.4% (11/450) and 26.7% (113/424) of the participants. Children with influenza were slightly older than those infected with RSV (10 months in influenza-infected children compared to 3 months in RSV-infected children); male children were predominant in both groups (63.6% versus 54.9% in children with influenza and RSV, respectively). There was a trend towards a higher frequency of influenza (72.7%) and RSV (93.8%) cases in the dry season. Bronchopneumonia, bronchitis and respiratory distress were the most common diagnoses at admission. Antibiotics were administered to 27,3% and 15,9% of the children with influenza and RSV, respectively. Two children, of whom, one was positive for RSV (aged 6 months) and another was positive for Influenza (aged 3 months) died; both were children of HIV seropositive mothers and had bronchopneumonia. CONCLUSIONS: Our data demonstrated that RSV, and less frequently influenza, occurs in children with SARI in urban/sub-urban settings from southern Mozambique. The occurrence of deaths in small children suspected of being HIV-infected, suggests that particular attention should be given to this vulnerable population. Our data also provide evidence of antibiotics prescription in children with respiratory viral infection, which represents an important public health problem and calls for urgent interventions. PMID- 29190685 TI - Evaluation of RNAi and CRISPR technologies by large-scale gene expression profiling in the Connectivity Map. AB - The application of RNA interference (RNAi) to mammalian cells has provided the means to perform phenotypic screens to determine the functions of genes. Although RNAi has revolutionized loss-of-function genetic experiments, it has been difficult to systematically assess the prevalence and consequences of off-target effects. The Connectivity Map (CMAP) represents an unprecedented resource to study the gene expression consequences of expressing short hairpin RNAs (shRNAs). Analysis of signatures for over 13,000 shRNAs applied in 9 cell lines revealed that microRNA (miRNA)-like off-target effects of RNAi are far stronger and more pervasive than generally appreciated. We show that mitigating off-target effects is feasible in these datasets via computational methodologies to produce a consensus gene signature (CGS). In addition, we compared RNAi technology to clustered regularly interspaced short palindromic repeat (CRISPR)-based knockout by analysis of 373 single guide RNAs (sgRNAs) in 6 cells lines and show that the on-target efficacies are comparable, but CRISPR technology is far less susceptible to systematic off-target effects. These results will help guide the proper use and analysis of loss-of-function reagents for the determination of gene function.

AB - Global positioning system (GPS) technologies have improved the ability of researchers to monitor wildlife; however, use of these technologies is often limited by monetary costs. Some researchers have begun to use commercially available GPS loggers as a less expensive means of tracking wildlife, but data regarding performance of these devices are limited. We tested a commercially available GPS logger (i-gotU GT-120) by placing loggers at ground control points with locations known to < 30 cm. In a preliminary investigation, we collected locations every 15 minutes for several days to estimate location error (LE) and circular error probable (CEP). Using similar methods, we then investigated the influence of cover on LE, CEP, and fix success rate (FSR) by constructing cover over ground control points. We found mean LE was < 10 m and mean 50% CEP was < 7 m. FSR was not significantly influenced by cover and in all treatments remained near 100%. Cover had a minor but significant effect on LE. Denser cover was associated with higher mean LE, but the difference in LE between the no cover and highest cover treatments was only 2.2 m. Finally, the most commonly used commercially available devices provide a measure of estimated horizontal position error (EHPE) which potentially may be used to filter inaccurate locations. Using data combined from the preliminary and cover investigations, we modeled LE as a function of EHPE and number of satellites. We found support for use of both EHPE and number of satellites in predicting LE; however, use of EHPE to filter inaccurate locations resulted in the loss of many locations with low error in return for only modest improvements in LE. Even without filtering, the accuracy of the logger was likely sufficient for studies which can accept average location errors of approximately 10 m.

AB - The hypothalamic-pituitary-adrenal (HPA) axis has been postulated to play a major role in mediating the antidiabetic effects of leptin. We tested if the pituitary is essential for the chronic central nervous system mediated actions of leptin on metabolic and cardiovascular function in insulin-dependent diabetic and non diabetic rats. Male 12-week-old hypophysectomized Sprague-Dawley rats (Hypo, n = 5) were instrumented with telemetry probes for determination of mean arterial pressure (MAP) and heart rate (HR) 24-hrs/day and an intracerebroventricular (ICV) cannula was placed into the brain lateral ventricle for continuous leptin infusion. In additional groups of Hypo and control rats (n = 5/group), diabetes was induced by single injection of streptozotocin (50 mg/kg, IP). Hypo rats were lighter, had lower MAP and HR (83+/-4 and 317+/-2 vs 105+/-4 mmHg and 339+/-4 bpm), with similar caloric intake per kilogram of body weight and fasting plasma glucose levels (84+/-4 vs 80+/-4 mg/dl) compared to controls. Chronic ICV leptin infusion (7 days, 0.62 MUg/hr) in non-diabetic rats reduced caloric intake and body weight (-10%) in Hypo and control rats and markedly increased HR in control rats (~25 bpm) while causing only modest HR increases in Hypo rats (8 bpm). In diabetic Hypo and control rats, leptin infusion reduced caloric intake, body weight and glucose levels (323+/-74 to 99+/-20 and 374+/-27 to 108+/-10 mg/dl), respectively; however, the effects of leptin on HR were abolished in Hypo rats. These results indicate that hypophysectomy attenuates leptin's effect on HR regulation without altering leptin's ability to suppress appetite or normalize glucose levels in diabetes.

AB - Non-muscle invasive bladder cancer is one of the most common tumors of the urinary tract. Despite the current multimodal therapy, recurrence and progression of disease have been challenging problems. We hereby introduced a new approach, ultrasound-assisted intravesical chemotherapy, intravesical instillation of chemotherapeutic agents and microbubbles followed by ultrasound exposure. We investigated the feasibility of the treatment for non-muscle invasive bladder cancer. In order to evaluate intracellular delivery and cytotoxic effect as a function to the thickness, we performed all experiments using a bladder cancer mimicking 3D culture model. Ultrasound-triggered microbubble cavitation increased both the intracellular platinum concentration and the cytotoxic effect of cisplatin at the thickness of 70 and 122 MUm of the culture model. The duration of enhanced cytotoxic effect of cisplatin by ultrasound-triggered microbubble cavitation was approximately 1 hr. Based on the distance and duration of delivery, we further tested the feasibility of repetition of the treatment. Triple treatment increased the effective distance by 1.6-fold. Our results clearly showed spatial and temporal profile of delivery by ultrasound-triggered microbubble cavitation in a tumor-mimicking structure. Furthermore, we demonstrated that the increase in intracellular concentration results in the enhancement of the cytotoxic effect in a structure with the certain thickness. Repetition of ultrasound exposure would be treatment of choice in future clinical application. Our results suggest ultrasound-triggered microbubble cavitation can be repeatable and is promising for the local control of non-muscle invasive bladder cancer. PMID- 29190689 TI - Trichomonicidal and parasite membrane damaging activity of bidesmosic saponins from Manilkara rufula. AB - The infection caused by Trichomonas vaginalis is the most common but overlooked non-viral sexually transmitted disease worldwide. Treatment relies on one class of drugs, the 5-nitroimidazoles, but resistance is widespread. New drugs are urgently needed. We reported the effect of crude and purified saponin fractions of Manilkara rufula against Trichomonas vaginalis. The compound responsible for antitrichomonal activity was isolated and identified as an uncommon bidesmosic saponin, Mi-saponin C. This saponin eliminated parasite viability without toxicity against the human vaginal epithelial line (HMVII). In addition, the isolated saponin fraction improved the metronidazole effect against a metronidazole-resistant isolate and dramatically reduced the cytoadherence of T. vaginalis to human cells. Investigation of the mechanism of death showed that the saponin fraction induced the parasite death due to profound membrane damage, inducing a disturbance of intracellular content without nuclear damage. To the best of our knowledge, this is the first report of antitrichomonal activity in the bidesmosic saponins of Manilkara rufula. PMID- 29190691 TI - Premedical special master's programs increase USMLE STEP1 scores and improve residency placements. AB - The effectiveness of Special Master's Programs (SMPs) in benefiting a potential medical student's career beyond admission into an MD-program is largely unknown. This study aims to evaluate the role of SMPs, if any, in affecting the performance and outcomes of students during their medical school career. This study analyzed anonymous surveys of students and residents from the University of Toledo. The data analysis is used to evaluate a student's academic performance before, during and after medical school. Measured metrics included: MCAT Scores, undergraduate GPA, USMLE STEP 1 scores, participation in research, number of research publications, and residency placement. Of 500 people surveyed 164 medical students or residents responded. Based on their responses, the respondents were divided into traditional (non-SMP) and SMP groups. As anticipated, MCAT scores (SMP: 29.82 vs. traditional 31.10) are significantly (p<0.05) different between the two groups. Interestingly, there is no significant difference in USMLE STEP 1 scores (SMP: 232.7 vs. traditional: 233.8) and when normalized relative to MCAT scores, USMLE STEP 1 scores for SMP-students are significantly (p<0.05) higher than their traditional counterparts (p<0.05). Additionally, SMP-students did not outperform the traditional students with regards to research publications. But, they did demonstrate a significant (p<0.05) proclivity towards surgical residencies when compared to the traditional students. Overall, our results highlight that SMPs potentiate USMLE STEP 1 performance and competitive residency-placements for its students. PMID- 29190690 TI - Development of effective tumor immunotherapy using a novel dendritic cell targeting Toll-like receptor ligand. AB - Although dendritic cell (DC)-based immunotherapy shows little toxicity, improvements should be necessary to obtain satisfactory clinical outcome. Using interferon-gamma injection along with DCs, we previously obtained significant clinical responses against small or early stage malignant tumors in dogs. However, improvement was necessary to be effective to largely developed or metastatic tumors. To obtain effective methods applicable to those tumors, we herein used a DC-targeting Toll-like receptor ligand, h11c, and examined the therapeutic effects in murine subcutaneous and visceral tumor models and also in the clinical treatment of canine cancers. In murine experiments, most and significant inhibition of tumor growth and extended survival was observed in the group treated with the combination of h11c-activated DCs in combination with interferon-gamma and a cyclooxygenase2 inhibitor. Both monocytic and granulocytic myeloid-derived suppressor cells were significantly reduced by the combined treatment. Following the successful results in mice, the combined treatment was examined against canine cancers, which spontaneously generated like as those in human. The combined treatment elicited significant clinical responses against a nonepithelial malignant tumor and a malignant fibrous histiocytoma. The treatment was also successful against a bone-metastasis of squamous cell carcinoma. In the successful cases, the marked increase of tumor-responding T cells and decrease of myeloid-derived suppressor cells and regulatory T cells was observed in their peripheral blood. Although the combined treatment permitted the growth of lung cancer of renal carcinoma-metastasis, the marked elevated and long-term maintaining of the tumor-responding T cells was observed in the patient dog. Overall, the combined treatment gave rise to emphatic amelioration in DC-based cancer therapy. PMID- 29190692 TI - Transcatheter arterial chemoembolization after stopping sorafenib therapy for advanced hepatocellular carcinoma. AB - Targeted therapy is currently the standard treatment for advanced hepatocellular carcinoma (HCC), but an effective treatment after the discontinuation of sorafenib therapy remains uncertain. We aim to investigate the survival benefits of transcatheter arterial chemoembolization (TACE) after stopping sorafenib therapy. We retrospectively analyzed all patients with advanced HCC, who had received palliative TACE after terminating sorafenib therapy, from January 2008 to June 2016. Patients who were in the terminal stage (Child-Pugh class C or performance status 3-4), who received a liver transplantation, or who had received any HCC treatment other than TACE, were excluded. Finally, 28 patients were recruited as the TACE group, and were randomly matched 1:1 by age, gender, Child-Pugh class, extrahepatic metastasis, and portal vein thrombosis with 28 controls who only received supportive care. For avoiding any immortal time bias, the index date of outcome follow-up was also matched. Cumulative incidences of, and hazard ratios (HRs) for, patient mortality were analyzed. The baseline demographic data between the TACE group and the control group were similar, but the 1-year overall survival rate in the TACE group was significantly higher than that of the control group (41.2%, 95% confidence interval [CI]: 19.4-63.0% vs. 24.5%, 95% CI: 6.3-42.7%; p < 0.01). In multivariate analysis, after adjusting for alpha-fetoprotein > 400ng/mL, Child-Pugh class B, and tumor extension > 50% of liver volume, TACE was independently associated with a decreased mortality risk(HR 0.19, 95% CI: 0.08-0.42). In addition, tumor extension > 50% of the liver was another independent prognostic factor associated with an increased mortality risk (HR 2.99, 95% CI: 1.31-6.82). Multivariate stratified analyses verified the association of TACE with a decreased mortality rate in each patient subgroup (all HR < 1.0). By controlling intrahepatic tumor growth, TACE may be a treatment option for use in improving patient survival in advanced HCC, after the termination of sorafenib therapy. PMID- 29190693 TI - Criterion validity of 8-item Morisky Medication Adherence Scale in patients with asthma. AB - The 8-item Morisky Medication Adherence Scale (MMAS-8) is reliable and valid in patients with hypertension, but to our knowledge validity has not been established for patients with asthma. The aim of the study was to determine the criterion validity of the MMAS-8 in patients with asthma. In the cross-sectional study patients older than 12 year were recruited when dispensed asthma medications in community pharmacies. Criterion validity of the scale was assessed through associations with asthma control and quality of life. Asthma control was assessed by the Asthma Control Test (ACT) and quality of life was evaluated by the Saint George Respiratory Questionnaire (SGRQ). A total of 208 patients (mean age 56 years, 59% female) were included in the study. Almost all patients were prescribed inhaled corticosteroids (96%). Asthma was not controlled in 37% of the patients and 22% experienced at least one exacerbation requiring emergency room visit, hospitalization or treatment with oral corticosteroid therapy in the previous year. The 8-item MMAS was significantly associated with asthma control and quality of life. Patients who scored 8 points, <8 to >6 points and <=6 points on the scale were considered to have high, medium and low adherence, respectively. High, medium and low adherence was found in 53%, 23% and 24% of the patients, respectively. As adherence improved from low to medium or from medium to high, the odds of asthma control increased by 1.7 times (OR 1.65, p = 0.027). Patients with high and medium adherence had SGRQ scores that were 6.1 and 5.3 points lower, respectively, compared with patients with low adherence. The MMAS-8 was found to be valid for assessing medication adherence and predicting health outcomes in patients with asthma. PMID- 29190694 TI - Contrast-enhanced magnetic resonance imaging for the detection of ruptured coronary plaques in patients with acute myocardial infarction. AB - PURPOSE: X-ray coronary angiography (XCA) is the current gold standard for the assessment of lumen encroaching coronary stenosis but XCA does not allow for early detection of rupture-prone vulnerable plaques, which are thought to be the precursor lesions of most acute myocardial infarctions (AMI) and sudden death. The aim of this study was to investigate the potential of delayed contrast enhanced magnetic resonance coronary vessel wall imaging (CE-MRCVI) for the detection of culprit lesions in the coronary arteries. METHODS: 16 patients (13 male, age 61.9+/-8.6 years) presenting with sub-acute MI underwent CE-MRCVI within 24-72h prior to invasive XCA. CE-MRCVI was performed using a T1-weighted 3D gradient echo inversion recovery sequence (3D IR TFE) 40+/-4 minutes following the administration of 0.2 mmol/kg gadolinium-diethylenetriamine-pentaacetic acid (DTPA) on a 3T MRI scanner equipped with a 32-channel cardiac coil. RESULTS: 14 patients were found to have culprit lesions (7x LAD, 1xLCX, 6xRCA) as identified by XCA. Quantitative CE-MRCVI correctly identified the culprit lesion location with a sensitivity of 79% and excluded culprit lesion formation with a specificity of 99%. The contrast to noise ratio (CNR) of culprit lesions (9.7+/ 4.1) significantly exceeded CNR values of segments without culprit lesions (2.9+/ 1.9, p<0.001). CONCLUSION: CE-MRCVI allows the selective visualization of culprit lesions in patients immediately after myocardial infarction (MI). The pronounced contrast uptake in ruptured plaques may represent a surrogate biomarker of plaque activity and/or vulnerability. PMID- 29190695 TI - High-accuracy detection of early Parkinson's Disease using multiple characteristics of finger movement while typing. AB - Parkinson's Disease (PD) is a progressive neurodegenerative movement disease affecting over 6 million people worldwide. Loss of dopamine-producing neurons results in a range of both motor and non-motor symptoms, however there is currently no definitive test for PD by non-specialist clinicians, especially in the early disease stages where the symptoms may be subtle and poorly characterised. This results in a high misdiagnosis rate (up to 25% by non specialists) and people can have the disease for many years before diagnosis. There is a need for a more accurate, objective means of early detection, ideally one which can be used by individuals in their home setting. In this investigation, keystroke timing information from 103 subjects (comprising 32 with mild PD severity and the remainder non-PD controls) was captured as they typed on a computer keyboard over an extended period and showed that PD affects various characteristics of hand and finger movement and that these can be detected. A novel methodology was used to classify the subjects' disease status, by utilising a combination of many keystroke features which were analysed by an ensemble of machine learning classification models. When applied to two separate participant groups, this approach was able to successfully discriminate between early-PD subjects and controls with 96% sensitivity, 97% specificity and an AUC of 0.98. The technique does not require any specialised equipment or medical supervision, and does not rely on the experience and skill of the practitioner. Regarding more general application, it currently does not incorporate a second cardinal disease symptom, so may not differentiate PD from similar movement-related disorders. PMID- 29190696 TI - Asymmetry of price returns-Analysis and perspectives from a non-extensive statistical physics point of view. AB - We study how the approach grounded on non-extensive statistical physics can be applied to describe and distinguish different stages of the stock and money market development. A particular attention is given to asymmetric behavior of fat tailed distributions of positive and negative returns. A new method to measure this asymmetry is proposed. It is based on the value of the non-extensive Tsallis parameter q. The new quantifier of the relative asymmetry level between tails in terms of the Tsallis parameters q+/- is provided to analyze the effect of memory in data caused by nonlinear autocorrelations. The presented analysis takes into account data of separate stocks from the main developing stock market in Europe, i.e., the Warsaw Stock Exchange (WSE) in Poland and-for comparison-data from the most mature money market (Forex). It is argued that the proposed new quantifier is able to describe the stage of market development and its robustness to speculation. The main strength is put on a description and interpretation of the asymmetry between statistical properties of positive and negative returns for various stocks and for diversified time-lags Deltat of data counting. The particular caution in this context is addressed to the difference between intraday and interday returns. Our search is extended to study memory effects and their dependence on the quotation frequency for similar large companies-owners of food-industrial retail supermarkets acting on both Polish and European markets (Eurocash, Jeronimo-Martins, Carrefour, Tesco)-but traded on various European stock markets of diversified economical maturity (respectively in Warsaw, Lisbon, Paris and London). The latter analysis seems to indicate quantitatively that stocks from the same economic sector traded on different markets within European Union (EU) may be a target of diversified level of speculations involved in trading independently on the true economic situation of the company. Our work thus gives indications that the statement:" where you are is more important than who you are" is true on trading markets.

PMID- 29190698 TI - Profiles of a broad spectrum of epigenetic DNA modifications in normal and malignant human cell lines: Proliferation rate is not the major factor responsible for the 5-hydroxymethyl-2'-deoxycytidine level in cultured cancerous cell lines. AB - Active demethylation of 5-methylcytosine moiety in DNA occurs by its sequential oxidation to 5-hydroxymethylcytosine, 5-formylcytosine and 5-carboxycytosine, catalysed by enzymes of the Ten-Eleven Translocation family proteins (TETs 1, 2 and 3). Here we analyzed for the first time all the intermediate products of DNA demethylation pathway in the form of deoxynucleosides (5-methyl-2'-deoxycytidine, 5-(hydroxymethyl)-2'-deoxycytidine, 5-formyl-2'-deoxycytidine and 5-carboxy-2' deoxycytidine as well as 5-(hydroxymethyl)-2'-deoxyuridine) using automated isotope-dilution online two-dimensional ultra-performance liquid chromatography with tandem mass spectrometry. DNA was isolated from human malignant cell lines of colon adenocarcinoma (HCT 116), melanoma (Me45), myelogenous leukemia bone marrow blasts (K562), EBV-positive Burkitt's lymphoma lymphoblasts (Raji), EBV negative Burkitt's lymphoma lymphoblasts (male-CA46 and female-ST486), as well as normal neonatal dermal fibroblasts (NHDF-Neo). The expression levels of TET1, TET2, TET3, SMUG1, and TDG genes were also assayed by RT-qPCR. Our results show a global erasure of 5-hydroxymethyl-2'-deoxycytidine and 5-carboxy-2'-deoxycytidine in DNA of cultured cells compared with DNA from primary malignant tissue. Moreover, malignant cells in culture have a quite different DNA epigenetic profile than cultured normal cells, and different types of malignant cells display different and characteristic profiles of DNA epigenetic marks. Similar analyses of a broader spectrum of epigenetic modifications, not restricted to 5 methyl-2'-deoxycytidine, could lead to better understanding of the mechanism(s) responsible for emergence of different types of cancer cells. PMID- 29190699 TI - Cost-effectiveness of expanding childhood routine immunization against Neisseria meningitidis serogroups C, W and Y with a quadrivalent conjugate vaccine in the African meningitis belt. AB - BACKGROUND: Neisseria meningitidis constitutes a major public health problem among countries in the African meningitis belt. Following regional vaccination campaigns for serogroup A and subsequent increases in protection against this serogroup, non-A serogroups such as C and W now pose significant epidemic threats, particularly in young children. OBJECTIVE: To evaluate the cost effectiveness of broadening coverage from conjugate serogroup A to quadrivalent ACWY vaccination. METHODS: We developed a 40-year Markov state transition model with annual cycles to simulate costs and clinical outcomes in children aged 1 to 10 in the 26 countries of the African meningitis belt. The incidence of CWY meningitis cases among an unvaccinated population was held constant at inter epidemic rates of 50 per 100,000/year and 150 per 100,000/year. The country specific cost and probability of access to meningitis care, vaccine efficacy, the mortality risk among treated and untreated meningitis cases, the risk of clinical sequelae and their respective disability weights were based on published sources. Vaccination cost was based on international prices lists, presented in 2014 US$. RESULTS: At an incidence rate of 50 per 100,000/year, routine conjugate vaccination is highly cost-effective in 14 out of 26 countries with a cost/DALY averted ranging from US$555-US$787. At the higher incidence rate of 150 per 100,000/year, quadrivalent vaccination is cost-effective in all 26 countries with a cost/DALY averted ranging from US$105-US$250. The annual incidence rate at which routine conjugate quadrivalent vaccination is expected to be economically justifiable ranges from 13 per 100,000/year in Nigeria to 142 per 100,000/year in Burundi. CONCLUSION: Routine quadrivalent conjugate vaccination against Neisseria meningitidis is cost-effective at incidence rates well below the epidemic threshold among children living in the African meningitis belt. PMID- 29190700 TI - Evaluation of the difference in caries experience in diabetic and non-diabetic children-A case control study. AB - AIM: To evaluate the caries prevalence and related variables in Type 1 diabetic and non-diabetic children and among the diabetic children according to their metabolic status. METHODS: Sixty-eight diabetic and 136 non-diabetic children, matching by gender and age (4-14 years) were enrolled. The diabetic children were divided: a) 20 children in good metabolic control (Hb1ac<=7.5) and b) 48 children in bad metabolic control (Hb1ac>7.5). Dietary and oral hygiene habits were investigated. Caries status was registered using the International Caries Detection and Assessment System. Oral microflora was analysed using the checkerboard DNA-DNA hybridisation method. Plaque acidogenicity was recorded after a sucrose rinse. RESULTS: Sugared beverage and snack intake was higher in diabetic group compared to non-diabetic group (p = 0.03 and p = 0.04, respectively) and in subjects in bad metabolic control (p = 0.03 and p<0.01, respectively). Oral hygiene habits were similar, except for the use of fluoridated adjuvants, higher in non-diabetic children (p = 0.04). No statistically significant differences were observed regarding caries figures, but a higher number of caries free subjects was found in diabetic subjects in good metabolic control (p<0.01). Significant difference for the main cariogenic bacteria was found between diabetic and non-diabetic subjects (p<0.05). The pH values showed statistically significant differences between diabetic and non diabetic subjects and between diabetic subjects in good and bad metabolic control (p<0.01). CONCLUSIONS: Diabetic children in good metabolic control might even be considered at low caries risk, while those in bad metabolic control showed an oral environment prone to a high caries risk. PMID- 29190702 TI - The infection and impact of Azorhizobium caulinodans ORS571 on wheat (Triticum aestivum L.). AB - Based on our previous study, cereal crop wheat (Triticum aestivum L.) could be infected by rhizobia Azorhizobium caulinodans ORS571, and form para-nodules with the induction of 2.4-dichlorophenoxyacetic acid, a common plant growth regulator. To enhance this infection and the potential agricultural application, we compared six different infection methods (Direct seed dip; Seed germination dip; Pruned root dip; Foliar spray; Circum-soil dip; Seed dip and circum-soil dip) for achieving the high efficient infection of A. caulinodans into wheat plants by employing a green fluorescent protein (gfp)-labeled Azorhizobium caulinodans strain ORS571. With proper methods, copious rhizobia could enter the interior and promote the growth of wheat to the hilt. Circum-soil dip was proved to be the most efficient method, seed germination dip and pruned-root dip is the last recommended to infect wheat, seed germination dip and seed dip and circum-soil dip showed better effects on plant growth, pruned-root dip did not show too much effect on plant growth. This study laid the foundation for understanding the interaction between rhizobia and cereal crops and the growth-promoting function of rhizobia. PMID- 29190701 TI - A non-threshold region-specific method for detecting rare variants in complex diseases. AB - A region-specific method, NTR (non-threshold rare) variant detection method, was developed-it does not use the threshold for defining rare variants and accounts for directions of effects. NTR also considers linkage disequilibrium within the region and accommodates common and rare variants simultaneously. NTR weighs variants according to minor allele frequency and odds ratio to combine the effects of common and rare variants on disease occurrence into a single score and provides a test statistic to assess the significance of the score. In the simulations, under different effect sizes, the power of NTR increased as the effect size increased, and the type I error of our method was controlled well. Moreover, NTR was compared with several other existing methods, including the combined multivariate and collapsing method (CMC), weighted sum statistic method (WSS), sequence kernel association test (SKAT), and its modification, SKAT-O. NTR yields comparable or better power in simulations, especially when the effects of linkage disequilibrium between variants were at least moderate. In an analysis of diabetic nephropathy data, NTR detected more confirmed disease-related genes than the other aforementioned methods. NTR can thus be used as a complementary tool to help in dissecting the etiology of complex diseases. PMID- 29190703 TI - Developing an eye-tracking algorithm as a potential tool for early diagnosis of autism spectrum disorder in children. AB - BACKGROUND: Autism spectrum disorder (ASD) currently affects nearly 1 in 160 children worldwide. In over two-thirds of evaluations, no validated diagnostics are used and gold standard diagnostic tools are used in less than 5% of evaluations. Currently, the diagnosis of ASD requires lengthy and expensive tests, in addition to clinical confirmation. Therefore, fast, cheap, portable, and easy-to-administer screening instruments for ASD are required. Several studies have shown that children with ASD have a lower preference for social scenes compared with children without ASD. Based on this, eye-tracking and measurement of gaze preference for social scenes has been used as a screening tool for ASD. Currently available eye-tracking software requires intensive calibration, training, or holding of the head to prevent interference with gaze recognition limiting its use in children with ASD. METHODS: In this study, we designed a simple eye-tracking algorithm that does not require calibration or head holding, as a platform for future validation of a cost-effective ASD potential screening instrument. This system operates on a portable and inexpensive tablet to measure gaze preference of children for social compared to abstract scenes. A child watches a one-minute stimulus video composed of a social scene projected on the left side and an abstract scene projected on the right side of the tablet's screen. We designed five stimulus videos by changing the social/abstract scenes. Every child observed all the five videos in random order. We developed an eye-tracking algorithm that calculates the child's gaze preference for the social and abstract scenes, estimated as the percentage of the accumulated time that the child observes the left or right side of the screen, respectively. Twenty-three children without a prior history of ASD and 8 children with a clinical diagnosis of ASD were evaluated. The recorded video of the child's eye movement was analyzed both manually by an observer and automatically by our algorithm. RESULTS: This study demonstrates that the algorithm correctly differentiates visual preference for either the left or right side of the screen (social or abstract scenes), identifies distractions, and maintains high accuracy compared to the manual classification. The error of the algorithm was 1.52%, when compared to the gold standard of manual observation. DISCUSSION: This tablet based gaze preference/eye-tracking algorithm can estimate gaze preference in both children with ASD and without ASD to a high degree of accuracy, without the need for calibration, training, or restraint of the children. This system can be utilized in low-resource settings as a portable and cost-effective potential screening tool for ASD. PMID- 29190704 TI - Electrocortical correlates of human level-ground, slope, and stair walking. AB - This study investigated electrocortical dynamics of human walking across different unconstrained walking conditions (i.e., level ground (LW), ramp ascent (RA), and stair ascent (SA)). Non-invasive active-electrode scalp electroencephalography (EEG) signals were recorded and a systematic EEG processing method was implemented to reduce artifacts. Source localization combined with independent component analysis and k-means clustering revealed the involvement of four clusters in the brain during the walking tasks: Left and Right Occipital Lobe (LOL, ROL), Posterior Parietal Cortex (PPC), and Central Sensorimotor Cortex (SMC). Results showed that the changes of spectral power in the PPC and SMC clusters were associated with the level of motor task demands. Specifically, we observed alpha and beta suppression at the beginning of the gait cycle in both SA and RA walking (relative to LW) in the SMC. Additionally, we observed significant beta rebound (synchronization) at the initial swing phase of the gait cycle, which may be indicative of active cortical signaling involved in maintaining the current locomotor state. An increase of low gamma band power in this cluster was also found in SA walking. In the PPC, the low gamma band power increased with the level of task demands (from LW to RA and SA). Additionally, our results provide evidence that electrocortical amplitude modulations (relative to average gait cycle) are correlated with the level of difficulty in locomotion tasks. Specifically, the modulations in the PPC shifted to higher frequency bands when the subjects walked in RA and SA conditions. Moreover, low gamma modulations in the central sensorimotor area were observed in the LW walking and shifted to lower frequency bands in RA and SA walking. These findings extend our understanding of cortical dynamics of human walking at different level of locomotion task demands and reinforces the growing body of literature supporting a shared-control paradigm between spinal and cortical networks during locomotion. PMID- 29190706 TI - Elderly emergency patients presenting with non-specific complaints: Characteristics and outcomes. AB - BACKGROUND: Non-specific complaints (NSC) are common at the emergency department, but only a few studies have shown evidence that these complaints are associated with a poor prognosis in elderly emergency patients. OBJECTIVE: To describe patient characteristics and outcomes in a cohort of elderly emergency patients presenting with NSC. Outcomes were: patient characteristics, hospitalization, 90 day ED-return visits, and 30-day mortality. METHOD: A retrospective cohort study was conducted amongst elderly patients present to the Internal Medicine Emergency Department (ED) between 01-09-2010 and 31-08-2011. NSC were defined as indefinable complaints that lack a pre-differential diagnosis needed to initiate of a standardized patient evaluation. Cox regression was performed to calculate Hazard Ratios (HR) and corrected for confounders such as comorbidity. RESULTS: In total, 1784 patients were enrolled; 244 (13.7%) presented with NSC. Compared to those with SC, comorbidity was higher in the NSC-group (Charlson comorbidity index 3.0 vs. 2.4, p<0.001). The triage level did not differ, but ED-length of stay was longer in the NSC-group (188 vs. 178 minutes, p = 0.004). Hospitalization was more frequent (84.0 vs. 71.1%, p<0.001) and the length of hospital stay (9 vs. 6 days, p<0.001 was longer in the NSC- than in the SC-group. The number of ED-return visits were comparable between both groups (HR 0.8, 95%CI 0.6-1.1). Mortality within 30-days was higher in the NSC- (20.1%) than in the SC group (11.0%, HR 1.7 95%CI 1.2-2.4). CONCLUSION: Elderly patients present with NSC at the ED regularly. These patients are more often hospitalized and have a substantially higher 30-day mortality than patients with SC. PMID- 29190705 TI - Arthritic role of Porphyromonas gingivalis in collagen-induced arthritis mice. AB - Epidemiological studies show an association between rheumatoid arthritis (RA) and periodontal disease. Porphyromonas gingivalis (P.gingivalis) is a well-known pathogen in periodontitis. This study investigated the pathogenic effects of P.gingivalis on autoimmune arthritis in vivo. Collagen-induced arthritis (CIA) mice were intraperitoneally injected with W83 and 2561 strains of P.gingivalis. Infection with P.gingivalis exacerbated arthritis score in CIA mice. Synovial inflammation and bone destruction in CIA mice infected with P.gingivalis were more severe than in uninfected CIA mice. Both W83 and 2561 strains were more pro arthritic after arthritis symptom was fully activated. Interestingly, only W83 strain was arthritogenic before autoimmune reaction initiated. Citrullination was detected in synovial tissue of CIA mice and CIA mice inoculated with P.gingivalis, but not in normal control mice. The citrullinated area was greater in P.gingivalis-infected CIA mice than in non-infected CIA mice. This study showed that P.gingivalis exacerbated disease in a mouse model of autoimmune arthritis and increased the expression of citrullinated antigens in the synovium. The arthritogenic effects of P.gingivalis were at least in part, dependent upon the bacterial strain with or without fimbriae expression, route and time of infection. P.gingivalis-mediated citrullination may explain the possible link between periodontal disease and RA. PMID- 29190707 TI - Hypofractionated stereotactic boost in intermediate risk prostate carcinoma: Preliminary results of a multicenter phase II trial (CKNO-PRO). AB - PURPOSE: Dose escalation may improve curability in intermediate-risk prostate carcinoma. A multicenter national program was developed to assess toxicity and tumor response with hypofractionated stereotactic boost after conventional radiotherapy in intermediate-risk prostate cancer. METHODS AND MATERIAL: Between August 2010 and April 2013, 76 patients with intermediated-risk prostate carcinoma were included in the study. A first course delivered 46 Gy by IMRT (68.4% of patients) or 3D conformal radiotherapy (31.6% of patients). The second course delivered a boost of 18 Gy (3x6Gy) within 10 days. Gastrointestinal (GI) and genitourinary (GU) toxicities were evaluated as defined by NCI-CTCAE (v4.0). Secondary outcome measures were local control, overall and metastasis-free survival, PSA kinetics, and patient functional status (urinary and sexual) according to the IIEF5 and IPSS questionnaires. RESULTS: The overall treatment time was 45 days (median, range 40-55). Median follow-up was 26.4 months (range, 13.6-29.9 months). Seventy-seven per cent (n = 58) of patients presented a Gleason score of 7. At 24 months, biological-free survival was 98.7% (95% CI, 92.8-99.9%) and median PSA 0.46 ng/mL (range, 0.06-6.20 ng/mL). Grade >=2 acute GI and GU toxicities were 13.2% and 23.7%, respectively. Grade >=2 late GI and GU toxicities were observed in 6.6% and 2.6% of patients, respectively. No grade 4 toxicity was observed. CONCLUSIONS: Hypofractionated stereotactic boost is effective and safely delivered for intermediate-risk prostate carcinoma after conventional radiation. Mild-term relapse-free survival and tolerance results are promising, and further follow-up is warranted to confirm the results at long term. TRIAL REGISTRATION: ClinicalTrials.gov NCT01596816. PMID- 29190708 TI - Human mobility prediction from region functions with taxi trajectories. AB - People in cities nowadays suffer from increasingly severe traffic jams due to less awareness of how collective human mobility is affected by urban planning. Besides, understanding how region functions shape human mobility is critical for business planning but remains unsolved so far. This study aims to discover the association between region functions and resulting human mobility. We establish a linear regression model to predict the traffic flows of Beijing based on the input referred to as bag of POIs. By solving the predictor in the sense of sparse representation, we find that the average prediction precision is over 74% and each type of POI contributes differently in the predictor, which accounts for what factors and how such region functions attract people visiting. Based on these findings, predictive human mobility could be taken into account when planning new regions and region functions. PMID- 29190709 TI - Relative muscle mass and the risk of incident type 2 diabetes: A cohort study. AB - AIMS: The association between relative muscle mass (RMM) and incidence of type 2 diabetes (T2DM) is largely unknown. We examined whether RMM predicted development of T2DM in an apparently young healthy population. METHODS: This cohort study was comprised of 113,913 men and 89,854 women, free of T2DM at baseline, who underwent a health checkup examination and were followed-up annually or biennially for an average of 2.9 years. We used skeletal muscle mass index (SMI) as an indicator of RMM. SMI (%) [total skeletal muscle mass (kg)/body weight (kg)*100] was estimated using a bioelectrical impedance analyzer. The study outcome was incident T2DM, defined as fasting serum glucose >=126 mg/dL, HbA1C >=6.5%, or use of medication for T2DM. RESULTS: During 589,098.8 person-years of follow-up, 4,264 individuals developed T2DM (incidence rate, 7.2 per 1000 person years). Median age (range) at baseline was 39.1 years (18.1-87.1). RMM was negatively associated with incidence of T2DM in a dose-response manner. The multivariate-adjusted hazard ratios (95% CIs) for incident T2DM comparing quartiles 3, 2 and 1 of RMM to the highest quartile were 1.32 (1.14-1.52), 1.63 (1.42-1.86), and 2.21 (1.94-2.51), respectively, for males and 1.18 (0.88-1.58), 1.46 (1.11-1.91), and 1.96 (01.51-2.53) for females (P for trend <0.001; 0.011). This association was stronger in younger or premenopausal subjects. CONCLUSIONS: RMM was negatively associated with development of T2DM in a large sample of young and middle-aged Korean adults. Further research is required to determine whether preservation of muscle mass through intervention affects the risk of T2DM. PMID- 29190710 TI - The association between depressive symptoms and insulin resistance, inflammation and adiposity in men and women. AB - INTRODUCTION: Depression has been shown to be associated with elevated leptin levels, low-grade inflammation and insulin resistance. These derangements are often measured in mixed gender cohorts despite the different body compositions and hormonal environments of men and women and gender-specific prevalence and responses to depression. METHODS: A cross-sectional analysis was carried out on a cohort of 639 participants from the ADDITION-Leicester dataset to assess differences in markers of diabetes risk, cardiovascular risk and inflammation in depressed and non-depressed individuals. Depressive symptoms were determined using the WHO (Five) well-being index. Multivariate linear and logistic regression analyses were adjusted for age, sex, ethnicity, body mass index, smoking, social deprivation and activity levels for continuous and binary variables respectively. Further analysis included stratifying the data by gender as well as assessing the interaction between depression and gender by including an interaction term in the model. RESULTS: Women with depressive symptoms had a 5.3% larger waist circumference (p = 0.003), 28.7% higher HOMA IR levels (p = 0.026), 6.6% higher log-leptin levels (p = 0.01) and 22.37% higher TNF-alpha levels (p = 0.015) compared with women without. Conversely, depressive symptoms in men were associated with 7.8% lower body fat % (p = 0.015) but 48.7% higher CRP levels (p = 0.031) compared to men without. However, interaction analysis failed to show a significant difference between men and women. CONCLUSIONS: Depressive symptoms are associated with metabolic derangements. Whilst women tended to show elevations in biomarkers related to an increased risk of type 2 diabetes (HOMA IR, leptin and TNF-alpha), men showed a marked increase in the cardiovascular disease risk biomarker CRP. However, perhaps due to the cohort size, interaction analysis did not show a significant gender difference. PMID- 29190711 TI - Engineering substrate promiscuity in halophilic alcohol dehydrogenase (HvADH2) by in silico design. AB - An alcohol dehydrogenase from the halophilic archaeon Haloferax volcanii (HvADH2) has been engineered by rational design to broaden its substrate scope towards the conversion of a range of aromatic substrates, including flurbiprofenol, that is an intermediate of the non-steroidal anti-inflammatory drug, flurbiprofen. Wild type HvADH2 showed minimal activity with flurbiprofenol (11.1 mU/mg). A homology model of HvADH2 was built and docking experiments with this substrate revealed that the biphenyl rings of flurbiprofenol formed strong interactions with residues F85 and F108, preventing its optimal binding in the active site. Mutations at position 85 however did not increase activity. Site directed mutagenesis at position F108 allowed the identification of three variants showing a significant (up to 2.3-fold) enhancement of activity towards flurbiprofenol, when compared to wild-type HvADH2. Interestingly, F108G variant did not show the classic inhibition in the presence of (R)-enantiomer when tested with rac-1 phenylethanol, underling its potential in racemic resolution of secondary alcohols. PMID- 29190712 TI - Replication capacity and adaptability of a severe fever with thrombocytopenia syndrome virus at different temperatures. AB - Severe fever with thrombocytopenia syndrome (SFTS) is an emerging disease caused by the SFTS virus (SFTSV). Although fever and thrombocytopenia are the typical manifestations of SFTS, a specific SFTS case with no fever was observed in Zhejiang, China. In this report, we aimed to explore the probable reason for the absence of fever by analyzing the genetic characteristics and temperature sensitivity (ts) of the SFTSV strain ZJ2013-06, which was isolated from the specific case. Phylogenetically, different clusters of SFTSV strains circulated in Zhejiang. ZJ2013-06 was farthest from ZJ2014-02, an isolate belonging to a Chinese dominant cluster, and nearest to the coastal strain NB24/CHN/2013. Ts tests, performed on Vero cells at 37 degrees C and 39 degrees C, indicated that ZJ2013-06 had restricted replication at 39 degrees C. Its viral loads were substantially reduced at 39 degrees C compared with that at 37 degrees C (approximately 100-fold reduction) and were significantly lower than that of ZJ2014-02 at 39 degrees C (P < 0.01). By adaptive culture at 39 degrees C, the induced strain ZJ2013-06-P7 was obtained. Owing to a reverse mutation (S1616), ZJ2013-06-P7 lost the ts of the original strain, displaying similar replication processes with NB24/CHN/2013. The results indicated that the amino acid residue 1616 was related to the ts characteristics of ZJ2013-06. Our study revealed that ZJ2013-06 was temperature-sensitive and may be related to the absence of fever in our case. PMID- 29190713 TI - Operational evaluation of rapid diagnostic testing for Ebola Virus Disease in Guinean laboratories. AB - BACKGROUND: Rapid Diagnostic Tests (RDTs) for Ebola Virus Disease (EVD) at the point of care have the potential to increase access and acceptability of EVD testing and the speed of patient isolation and secure burials for suspect cases. A pilot program for EVD RDTs in high risk areas of Guinea was introduced in October 2015. This paper presents concordance data between EVD RDTs and PCR testing in the field as well as an assessment of the acceptability, feasibility, and quality assurance of the RDT program. METHODS AND FINDINGS: Concordance data were compiled from laboratory surveillance databases. The operational measures of the laboratory-based EVD RDT program were evaluated at all 34 sentinel sites in Guinea through: (1) a technical questionnaire filled by the lab technicians who performed the RDTs, (2) a checklist filled by the evaluator during the site visits, and (3) direct observation of the lab technicians performing the quality control test. Acceptability of the EVD RDT was good for technicians, patients, and families although many technicians (69.8%) expressed concern for their safety while performing the test. The feasibility of the program was good based on average technician knowledge scores (6.6 out of 8) but basic infrastructure, equipment, and supplies were lacking. There was much room for improvement in quality assurance of the program. CONCLUSIONS: The implementation of new diagnostics in weak laboratory systems requires general training in quality assurance, biosafety and communication with patients in addition to specific training for the new test. Corresponding capacity building in terms of basic equipment and a long-term commitment to transfer supervision and quality improvement to national public health staff are necessary for successful implementation. PMID- 29190714 TI - Biomarkers of IgA vasculitis nephritis in children. AB - Henoch-Schonlein purpura is a systemic vasculitis characterized by IgA deposits, which target the skin, joints, and kidneys, among other organs. In children, prognosis is often good but little is known about biomarkers of pediatric nephritis. We hypothesized that biological markers, including cytokines, immunoglobulins, IgA-immune complexes, IgA glycosylation and neutrophil gelatinase-associated lipocalin (NGAL), may discriminate IgA vasculitis (IgAV) pediatric patients with renal involvement from those without renal involvement. Fifty children at the time of IgAV rash between 2010 and 2015 were prospectively enrolled and compared to 21 controls. All patients were assessed for clinical and biological parameters at the time of diagnosis, including the levels of cytokines, immunoglobulins, immune complexes, IgA glycosylation and NGAL in serum and urine. Among IgAV patients, 33 patients exhibited nephritis (IgAV-N) and 17 children were without nephritis (IgAV-woN). The serum level of galactose deficient (Gd)-IgA1 (p<0.01) and the urinary concentrations of IgA, IgG, IgM, IL 6, IL-8, IL-10, IgA-IgG complexes and IgA-sCD89 complexes (p<0.001 for all) were higher in the IgAV-N patients than in the IgAV-woN patients. Among those markers, urinary IgA and IgM had the highest AUC (0.86 and 0.87 respectively, p<0.0001). This prospective cohort study furthers our understanding of the pathophysiology of IgAV. We identified biomarkers that are able to distinguish patients initially with or without nephritis. To conclude, serum Gd-IgA1 and urinary IgA, IgG, IgM, IL-6, IL-8, IL-10, and IgA-IgG and IgA-sCD89 complexes could identify IgAV pediatric patients with renal involvement at the time of diagnosis. PMID- 29190715 TI - A history of repetitive cesarean section is a risk factor of anemia in healthy perimenopausal women: The Korea National Health and Nutrition Examination Survey 2010-2012. AB - BACKGROUND AND OBJECTIVES: To determine whether the delivery method is associated with the rate of anemia in later life, using the data from the Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: This study used data from the KNHANES 2010-2012. Among 25,534 participants, 8,126 cases were included in this study after exclusion of males and other inappropriate data. The study population was divided into three groups according to the delivery modes: vaginal delivery (VD) only group, single cesarean delivery (SCD) group and repetitive cesarean delivery (RCD) group. The primary outcome was anemia and iron deficiency. Anemia was defined as hemoglobin <12 g/dl in accordance with the World Health Organization criteria. Iron deficiency was defined as low transferrin saturation (TSAT) or ferritin levels. Multivariate analysis was used for determination of association between the delivery modes and anemia. RESULTS: The mean age was 53.4 years and the median time from the last delivery to the survey was 25 years. The VD only group was composed of 6,493 (79.9%) women, while 685 (8.4%) were classified as the SCD group and 948 (11.7%) were classified as a RCD group. The rates of anemia were 11.8%, 13.9%, and 19.7% in VD only group, SCD group, and RCD group, respectively. However, those groups were significantly different in many confounding factors. Therefore, to adjust those factors, multivariate analysis and subgroup analysis were followed. The odds of SCD for anemia and iron deficiency were not different from those of VD only. However, RCD was independently associated with anemia [Odds ratio(OR) 1.47, 95% Confidence interval (CI) 1.21-1.79, P <0.001] and iron deficiency (OR 1.42, 95% CI 1.21 1.67, P <0.001) compared to VD only. In the subgroup analysis, RCD was significantly associated with anemia in perimenopausal women, women with iron deficiency, those without any comorbidity and those without anemia-prone treatment. CONCLUSION: Repetitive cesarean section may be a risk factor for future development of anemia in later life, especially in perimenopausal period. Therefore, evaluation and management of anemia in longer postpartum period should be considered for women who experience repetitive cesarean section. PMID- 29190716 TI - Suppression of cancer stemness by upregulating Ligand-of-Numb protein X1 in colorectal carcinoma. AB - Cancer stem-like cells (CSCs) have been reported to play major roles in tumorigenesis, tumor relapse, and metastasis after therapy against colorectal carcinoma (CRC). Therefore, identification of colorectal CSC regulators could provide promising targets for CRC. Ligand-of-Numb protein X1 (LNX1) is one E3 ubiquitin ligase which mediates the ubiquitination and degradation of Numb. Although several studies indicate LNX1 could be a potential suppressor of cancer diseases, the functions of LNX1 in mediating cancer stemness remain poorly understood. In this study, LNX1 was identified as a negative regulator of cancer stemness in CRC, which was downregulated in colonospheres or side population (SP) cells. Furthermore, the coxsackievirus and adenovirus receptor (CXADR) was found to be one critical downstream mediator of cancer stemness regulated by LNX1. Interestingly, the anti-breast cancer drug tamoxifen was found to be an agonist of LNX1 and suppress cancer stemness in CRC. In sum, this study provided the evidences that LNX1 signaling plays important roles in regulating the stemness of colon cancer cells. PMID- 29190717 TI - Impact of chemotherapy on perceptions related to food intake in women with breast cancer: A prospective study. AB - Breast cancer (BC) treatment includes mostly chemotherapy (CT), which can cause side effects like nausea, taste changes, early satiety, slow gastric emptying and xerostomia. In this way, the individual's relationship with food may change during the treatment. The aim of this study was to evaluate the impact of chemotherapy on perceptions related to food intake of women with BC. Fifty-five women with BC were followed, and data were collected at three periods during first-line CT: beginning (T0), intermediate (T1) and end (T2). A visual analogue scale (VAS) (0 to 10 cm) for hunger, appetite for various food categories and meal enjoyment was investigated. The frequency and intensity of side effects were evaluated using a 4 cm scale. The results showed a higher prevalence of taste changes in T1 (p = 0.044) and more nausea in T1 and T2 (p = 0.018). Furthermore, the intensity of nausea was higher in T2 (p = 0.01) than in the other periods. We observed moderate hunger in T0, T1 and T2 (p = 0.113), but the overall appetite increased between T0 and T2 (p = 0.003). Meal enjoyment was reduced from T0 to T1and returned back to the initial value in T2 (p = 0.021). The appetite for salty (p = 0.004) and spicy (p = 0.03) foods was increased in T1. There was an increase of body weight (p = 0.008), body mass index (BMI) (p = 0.009) and waist circumference (WC) (p = 0.03) during CT. CT changes food hedonism, increasing the overall appetite and the appetite for salty and spicy foods. Moreover, we observed the negative impact of CT on meal enjoyment and an increase in side effects and anthropometric parameters. PMID- 29190718 TI - Investigating the validity of the DN4 in a consecutive population of patients with chronic pain. AB - Neuropathic pain is clinically described as pain caused by a lesion or disease of the somatosensory nervous system. The aim of this study was to assess the validity of the Dutch version of the DN4, in a cross-sectional multicentre design, as a screening tool for detecting a neuropathic pain component in a large consecutive, not pre-stratified on basis of the target outcome, population of patients with chronic pain. Patients' pain was classified by two independent (pain-)physicians as the gold standard. The analysis was initially performed on the outcomes of those patients (n = 228 out of 291) in whom both physicians agreed in their pain classification. Compared to the gold standard the DN4 had a sensitivity of 75% and specificity of 76%. The DN4-symptoms (seven interview items) solely resulted in a sensitivity of 70% and a specificity of 67%. For the DN4-signs (three examination items) it was respectively 75% and 75%. In conclusion, because it seems that the DN4 helps to identify a neuropathic pain component in a consecutive population of patients with chronic pain in a moderate way, a comprehensive (physical-) examination by the physician is still obligate. PMID- 29190719 TI - Breakfast habits and differences regarding abdominal obesity in a cross-sectional study in Spanish adults: The ANIBES study. AB - BACKGROUND: Previous studies have indicated that breakfast has a protective effect against obesity. The aim of this study was to describe the breakfast habits of the Spanish adult population and to assess the possible association between breakfast frequency and the presence of abdominal obesity, in a cross sectional analysis of the ANIBES Study. METHODS: A representative sample of 1655 Spanish adults (aged 39+/-12 y; (mean+/-sd)) from the ANIBES Study was investigated. The final field work was carried out from mid-September to November (three months) 2013. Collected data included a dietary data collected by a 3-days food record, and health, socioeconomic, physical activity and anthropometric (weight, height and waist circumference) data. Abdominal obesity was defined as having a waist-to-height ratio >=0.5. The adults were also classified into three groups based on the number of days they ate breakfast (never (0/3 days), sometimes (1-2/3 days) and always (3/3 days)). Logistic regression analyses were used to evaluate the association between breakfast and abdominal obesity. RESULTS: In total, 3.6% of adults skipped breakfast and 14.1% ate breakfast sometimes. Having always breakfast was negatively associated with abdominal obesity [OR = 0.738 (0.558-0.975) p = 0.033]. The odds of abdominal obesity after full adjustment (age, gender, and educational and activity level) were 1.5 times higher for those who skipped breakfast when compared to those who always have breakfast. By correcting the model considered for other variables, the odds among smokers decreased when they have breakfast sometimes [OR = 0.032 (0.003-0.387) p = 0.007] and always [OR = 0.023 (0.002-0.270) p = 0.003] comparing with smokers who skip breakfast. CONCLUSION: Breakfast frequency could be negatively associated with abdominal obesity, especially among smokers. PMID- 29190720 TI - Intramyocellular triacylglycerol accumulation across weight loss strategies; Sub study of the CENTRAL trial. AB - BACKGROUND: Intramyocellular triacylglycerol (IMTG) is utilized as metabolic fuel during exercise and is linked to insulin resistance, but the long-term effect of weight loss strategies on IMTG among participants with abdominal fat, remain unclear. METHODS: In an 18-month trial, sedentary participants with abdominal fat/dyslipidemia were randomized to either a low-fat (LF) or Mediterranean/low carbohydrate (MED/LC) diet (including 28g.day-1 of walnuts). After 6-months, the participants were re-randomized to moderate intense physical activity (PA+) or non-physical activity (PA-). Magnetic resonance imaging (MRI) was used to quantify changes of IMTG, abdominal sub-depots, hepatic and intermuscular fats. RESULTS: Across the 277 participants [86% men, age = 48 years, body-mass-index (BMI) = 31kg/m2, visceral fat = 33%] 86% completed the 18-m trial. At baseline, women had higher IMTG than men (3.4% vs. 2.3%, p<0.001) and increased IMTG was associated with aging and higher BMI, visceral and intermuscular fats, HbA1c%, HDL-c and leptin(p<0.05), but not with intra-hepatic fat. After 18 month of intervention and a -3 kg mean weight loss, participants significantly increased IMTG by 25%, with a distinct effect in the MED/LCPA+ group as compared to the other intervention groups (57% vs. 9.5-18.5%, p<0.05). Changes in IMTG were associated with visceral and intermuscular fat, metabolic syndrome, insulin and leptin (p<0.05 for all), however, these associations did not remain after adjustment for visceral fat changes. CONCLUSIONS: Lifestyle strategies differentially affect IMTG accumulation; combination of exercise with decreased carbohydrate/increased unsaturated fat proportion intake greatly increase IMTG. Our findings suggest that increased IMTG during diet-induced moderate weight loss may not be directly related to cardiometabolic risk. TRIAL REGISTRATION: ClinicalTrials.gov NCT01530724. PMID- 29190721 TI - Carriage of Staphylococcus aureus among Portuguese nursing students: A longitudinal cohort study over four years of education. AB - BACKGROUND: Staphylococcus aureus is a major human pathogen that can colonize healthy people mainly in the anterior nares. The aim of the present study was to evaluate S. aureus nasal colonization over time among Portuguese nursing students, including methicillin-resistant S. aureus (MRSA). METHODS AND FINDINGS: In this longitudinal cohort study, we collected 280 nasal swabs from nursing students at 14 time points over four years of schooling (2012-2016). The isolates were characterized by pulsed-field gel electrophoresis (PFGE), spa typing, multilocus sequence typing (MLST), and SCCmec typing for MRSA. Among 47 students, 20 (43%) carried methicillin-susceptible S. aureus (MSSA) at admission, but none was colonized with MRSA. A total of 19 students (40%) became colonized after exposure during the nursing training, out of which five carried MRSA. Overall, 39 students (83%) had S. aureus detected at least once during the study period. Among the 97 MSSA isolates, most (65%) belonged to four clones: PFGE A-ST30 (21%), B-ST72 (20%), C-ST508 (13%), and D-ST398 (11%). Three of the five MRSA carriers were colonized with the predominant clone circulating in Portuguese hospitals (ST22-IVh) and two with ST3162-II. Colonization of nursing students was highly dynamic with continuous appearance of strains with distinct PFGE types in the same individual. CONCLUSIONS: A considerable proportion of students became colonized by S. aureus, including MRSA, during the nursing education, evidencing this population represents an important reservoir of S. aureus. Therefore, education on infection control measures in nursing schools is of major importance. PMID- 29190722 TI - Association between grip strength and hand and knee radiographic osteoarthritis in Korean adults: Data from the Dong-gu study. AB - OBJECTIVES: We assessed whether grip strength was related to various types of radiographic damage in Korean adults with osteoarthritis (OA). METHODS: Data from 2,251 subjects enrolled in the Dong-gu study, who had no hand joint pain, were analyzed to investigate the relationship between grip strength and OA. Hand grip strength was measured using a hand-held dynamometer, and radiographs of the hand and knee were scored according to a semi-quantitative grading system. Multiple linear regressions were used to explore associations between grip strength and radiographic features of OA. RESULTS: Grip strength in men and women was negatively related to hand (both p < 0.001) and knee (men, p < 0.001; women, p = 0.010) OA after adjusting for confounders. Hand (men, p < 0.001; women, p = 0.001) and knee (both p < 0.001) joint space narrowing (JSN) showed the strongest associations with low grip strength, regardless of gender. Moreover, the severity of hand osteophytes in women (p = 0.001), and subchondral cysts (men, p < 0.001) was correlated with low grip strength in both genders. CONCLUSIONS: Among subjects without hand joint pain, low grip strength was associated significantly with hand and knee radiographic OA, regardless of gender. Among all types of OA radiographic damage, low grip strength showed the strongest association with JSN. PMID- 29190723 TI - Effects of increasing temperature and, CO2 on quality of litter, shredders, and microorganisms in Amazonian aquatic systems. AB - Climate change may affect the chemical composition of riparian leaf litter and, aquatic organisms and, consequently, leaf breakdown. We evaluated the effects of different scenarios combining increased temperature and carbon dioxide (CO2) on leaf detritus of Hevea spruceana (Benth) Mull. and decomposers (insect shredders and microorganisms). We hypothesized that simulated climate change (warming and elevated CO2) would: i) decrease leaf-litter quality, ii) decrease survival and leaf breakdown by shredders, and iii) increase microbial leaf breakdown and fungal biomass. We performed the experiment in four microcosm chambers that simulated air temperature and CO2 changes in relation to a real-time control tracking current conditions in Manaus, Amazonas, Brazil. The experiment lasted seven days. During the experiment mean air temperature and CO2 concentration ranged from 26.96 +/- 0.98oC and 537.86 +/- 18.36 ppmv in the control to 31.75 +/ 0.50oC and 1636.96 +/- 17.99 ppmv in the extreme chamber, respectively. However, phosphorus concentration in the leaf litter decreased with warming and elevated CO2. Leaf quality (percentage of carbon, nitrogen, phosphorus, cellulose and lignin) was not influenced by soil flooding. Fungal biomass and microbial leaf breakdown were positively influenced by temperature and CO2 increase and reached their highest values in the intermediate condition. Both total and shredder leaf breakdown, and shredder survival rate were similar among all climatic conditions. Thus, low leaf-litter quality due to climate change and higher leaf breakdown under intermediate conditions may indicate an increase of riparian metabolism due to temperature and CO2 increase, highlighting the risk (e.g., decreased productivity) of global warming for tropical streams. PMID- 29190724 TI - Socioeconomic characterization of regions through the lens of individual financial transactions. AB - People are increasingly leaving digital traces of their daily activities through interacting with their digital environment. Among these traces, financial transactions are of paramount interest since they provide a panoramic view of human life through the lens of purchases, from food and clothes to sport and travel. Although many analyses have been done to study the individual preferences based on credit card transaction, characterizing human behavior at larger scales remains largely unexplored. This is mainly due to the lack of models that can relate individual transactions to macro-socioeconomic indicators. Building these models, not only can we obtain a nearly real-time information about socioeconomic characteristics of regions, usually available yearly or quarterly through official statistics, but also it can reveal hidden social and economic structures that cannot be captured by official indicators. In this paper, we aim to elucidate how macro-socioeconomic patterns could be understood based on individual financial decisions. To this end, we reveal the underlying interconnection of the network of spending leveraging anonymized individual credit/debit card transactions data, craft micro-socioeconomic indices that consists of various social and economic aspects of human life, and propose a machine learning framework to predict macro-socioeconomic indicators.

AB - BACKGROUND: No study has estimated the potential impact of Human Papillomavirus (HPV) vaccination in Puerto Rico, a population with considerable burden of HPV related morbidities. We evaluated the health and economic impacts of implementing a vaccination strategy for females and males in Puerto Rico, with the quadrivalent HPV (HPV4) vaccine, under different vaccination scenarios. METHODS: We adapted a mathematical model which estimates the direct and indirect health benefits and costs of HPV4 vaccination in a dynamic population. The model compared three vaccination scenarios against screening only (no-vaccination) for three doses of HPV4 vaccine among individuals aged 11-15 years in Puerto Rico: 1) 34% for females and 13% for males (34%F/13%M), 2) 50% for females and 40% for males (50%F/40%M), and 3) 80% for female and 64% for male (80%F/64%M). Data specific to Puerto Rico was used. When not available, values from the United States were used. Input data consisted of demographic, behavioral, epidemiological, screening, and economic parameters. RESULTS: The model predicted decreases in: 1) HPV infection prevalence for females and males, 2) cervical intraepithelial neoplasia and cervical cancer incidence for females, 3) genital warts incidence for females and males, and 4) cervical cancer deaths among females, when various vaccination program scenarios were considered. In addition, when the vaccination percentage was increased in every scenario, the reduction was greater and began earlier. The analysis also evidenced an incremental cost effectiveness ratio (ICER) of $1,964 per quality-adjusted life year gained for the 80%F/64%M uptake scenario. CONCLUSIONS: HPV vaccine can prove its cost effectiveness and substantially reduce the burden and costs associated to various HPV-related conditions when targeted to the adequate population together with an organized HPV vaccination program. PMID- 29190726 TI - Socio-demographic, health-related, and individual correlates of diagnostic self testing by lay people: Results from a representative survey in Germany. AB - INTRODUCTION: A broad range of self-tests (testing for e.g. HIV, cancer, hepatitis B/C) have become available and can be conducted by lay consumers without the help of a health professional. The aims of this study were to (a) investigate the prevalence of self-testing, (b) identify the most frequently used self-tests, and (c) explore the associations between socio-demographic, health related and individual factors with self-testing. METHODS: A face-to-face plus paper-pencil cross-sectional survey was conducted. The sample consisted of 2.527 respondents who were representative of the German population in terms of the age, sex, and residence. Basic descriptive statistics and univariate logistic regression analyses were performed. RESULTS: 8.5% of the participants reported having used one or more self-tests in the past, totalling 363 self-tests, with a mean of 1.7 (min. = 1, max. = 6). The three self-tests most frequently indicated were for detecting diabetes, bowel cancer, and allergies. Self-testers were older (Nagelkerke R2 = .006, p < .01), had a higher BMI (Nagelkerke R2 = .013, p < .001) and displayed more physical and mental fatigue (Nagelkerke R2 = .031, p < .001) than non-testers. Self-testers also reported higher global life satisfaction values (Nagelkerke R2 = .008, p < .01) and a higher educational level (Nagelkerke R2 = .015, p < .01). CONCLUSIONS: Self-testing is fairly prevalent in Germany Given the current shortage of physicians in Germany, especially in rural areas, and recent studies on the use of self-medication, the topic of self-testing has a great practical and socio-political relevance. Future studies should investigate further predictors of self-testing (e.g. contextual, situational and individual factors) as well as the emotional consequences of testing as a layperson without the attendance of a health professional. PMID- 29190727 TI - Influence of the type of training task on intermanual transfer effects in upper limb prosthesis training: A randomized pre-posttest study. AB - Intermanual transfer, the transfer of motor skills from the trained hand to the untrained hand, can be used to train upper limb prosthesis skills. The aim of this study was to determine the relation between the magnitude of the intermanual transfer effect and the type of training task. The used tasks were based on different aspects of prosthetic handling: reaching, grasping, grip-force production and functional tasks. A single-blinded clinical trial, with a pre posttest design was executed. Seventy-one able-bodied, right-handed participants were randomly assigned to four training and two control groups. The training groups performed a training program with an upper-limb prosthesis simulator. One control group performed a sham training (a dummy training without the prosthesis simulator) and another control group received no training at all. The training groups and sham group trained on five consecutive days. To determine the improvement in skills, a test was administered before, immediately after, and one week after the training. Training was performed with the 'unaffected' arm; tests were performed with the 'affected' arm, with the latter resembling the amputated limb. In this study half of the participants trained with the dominant hand, while the other half trained with the non-dominant hand. Participants executed four tests that corresponded to the different training tasks. The tests measured the reaching (movement time and symmetry ratio), grasping (opening time, duration of maximum hand opening, and closing time), grip-force production (deviation of asked grip-force) and functional (movement time) performance. Half of the participants were tested with their dominant arm and half of the participants with their non-dominant arm. Intermanual transfer effects were not found for reaching, grasping or functional tasks. However, we did find intermanual transfer effects for grip-force production tasks. Possibly, the study design contributed to the negative results due to the duration of the training sessions and test sessions. The positive results of the grip-force production might be an effect of the specificity of the training, that was totally focused on training grip-force production. When using intermanual transfer training in novice amputees, specific training should be devoted to grip-force. PMID- 29190728 TI - Chagas disease vector control and Taylor's law. AB - BACKGROUND: Large spatial and temporal fluctuations in the population density of living organisms have profound consequences for biodiversity conservation, food production, pest control and disease control, especially vector-borne disease control. Chagas disease vector control based on insecticide spraying could benefit from improved concepts and methods to deal with spatial variations in vector population density. METHODOLOGY/PRINCIPAL FINDINGS: We show that Taylor's law (TL) of fluctuation scaling describes accurately the mean and variance over space of relative abundance, by habitat, of four insect vectors of Chagas disease (Triatoma infestans, Triatoma guasayana, Triatoma garciabesi and Triatoma sordida) in 33,908 searches of people's dwellings and associated habitats in 79 field surveys in four districts in the Argentine Chaco region, before and after insecticide spraying. As TL predicts, the logarithm of the sample variance of bug relative abundance closely approximates a linear function of the logarithm of the sample mean of abundance in different habitats. Slopes of TL indicate spatial aggregation or variation in habitat suitability. Predictions of new mathematical models of the effect of vector control measures on TL agree overall with field data before and after community-wide spraying of insecticide. CONCLUSIONS/SIGNIFICANCE: A spatial Taylor's law identifies key habitats with high average infestation and spatially highly variable infestation, providing a new instrument for the control and elimination of the vectors of a major human disease. PMID- 29190729 TI - Increased MMAB level in mitochondria as a novel biomarker of hepatotoxicity induced by Efavirenz. AB - BACKGROUND: Efavirenz (EFV), a non-nucleoside reverse transcriptase inhibitor (NNRTI), has been widely used in the therapy of human immunodeficiency virus (HIV) infection. Some of its toxic effects on hepatic cells have been reported to display features of mitochondrial dysfunction through bioenergetic stress and autophagy, etc. However, alteration of protein levels, especially mitochondrial protein levels, in hepatic cells during treatment of EFV has not been fully investigated. METHODS: We built a cell model of EFV-induced liver toxicity through treating Huh-7 cells with different concentrations of EFV for different time followed by the analysis of cell viability using cell counting kit -8 (CCK8) and reactive oxygen species (ROS) using 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) and MitoSox dye. Proteomic profiles in the mitochondria of Huh-7 cells stimulated by EFV were analyzed. Four differentially expressed proteins were quantified by real time RT-PCR. We also detected the expression of mitochondrial precursor Cob(I)yrinic acid a,c-diamide adenosyltransferase (MMAB) by immunohistochemistry analysis in clinical samples. The expression levels of MMAB and ROS were detected in EFV-treated Huh-7 cells with and without shRNA used to knock down MMAB, and in primary hepatocytes (PHC). The effects of other anti HIV drugs (nevirapine (NVP) and tenofovirdisoproxil (TDF)), and hydrogen peroxide (H2O2) were also tested. Amino acid analysis and fatty aldehyde dehydrogenase (ALDH3A2) expression after MMAB expression knock-down with shRNA was used to investigate the metabolic effect of MMAB in Huh-7 cells. RESULTS: EFV treatment inhibited cell viability and increased ROS production with time- and concentration-dependence. Proteomic study was performed at 2 hours after EFV treatment. After treated Huh-7 cells with EFV (2.5mg/L or 10 mg/L) for 2 h, fifteen differentially expressed protein spots from purified mitochondrion that included four mitochondria proteins were detected in EFV-treated Huh-7 cells compared to controls. Consistent with protein expression levels, mRNA expression levels of mitochondrial protein MMAB were also increased by EFV treatment. In addition, the liver of EFV-treated HIV infected patients showed substantially higher levels of MMAB expression compared to the livers of untreated or protease inhibitor (PI)-treated HIV-infected patients. Furthermore, ROS were found to be decreased in Huh-7 cells treated with shMMAB compared with empty plasmid treated with EFV at the concentration of 2.5 or 10 mg/L. MMAB was increased in EFV treated Huh-7 cells and primary hepatocytes. However, no change in MMAB expression was detected after treatment of Huh-7 cells and primary hepatocytes with anti-HIV drugs nevirapine (NVP) and tenofovirdisoproxil (TDF), or hydrogen peroxide (H2O2), although ROS was increased in these cells. Finally, knockdown of MMAB by shRNA induced increases in the beta-Alanine (beta-Ala) production levels and decrease in ALDH3A2 expression. CONCLUSIONS: A mitochondrial proteomic study was performed to study the proteins related to EFV-inducted liver toxicity. MMAB might be a target and potential biomarker of hepatotoxicity in EFV-induced liver toxicity. PMID- 29190730 TI - Increased levels of plasma total tau in adult Down syndrome. AB - Down syndrome (DS) is the most prevalent chromosomal abnormality. Early-onset dementia with the pathology of Alzheimer's disease (AD) frequently develops in DS. Reliable blood biomarkers are needed to support the diagnosis for dementia in DS, since positron emission tomography or cerebrospinal fluid sampling is burdensome, particularly for patients with DS. Plasma t-tau is one of the established biomarkers for the diagnosis of AD, suggesting the potential value of t-tau as a biomarker for dementia in DS. The aim of this study was to assess and compare plasma levels of t-tau in adults with DS and in an age-matched control population. In this study, plasma levels of t-tau in 21 patients with DS and 22 control participants were measured by an ultrasensitive immunoassay technology, the single-molecule immunoarray (Simoa) method. We observed significantly increased plasma t-tau levels in the DS group (mean +/- standard deviation (SD) = 0.643+/-0.493) compared to those in the control group (mean +/- SD = 0.470+/ 0.232): P = 0.0050. Moreover, age dependent correlation of plasma t-tau was only found in the DS group, and not in the control group. These findings suggest that elevated plasma t-tau levels reflect AD pathology and therefore have potential as an objective biomarker to detect dementia in adult DS. PMID- 29190731 TI - Newly identified risk factors for MRSA carriage in The Netherlands. AB - OBJECTIVES: To elucidate new risk factors for MRSA carriers without known risk factors (MRSA of unknown origin; MUO). These MUO carriers are neither pre emptively screened nor isolated as normally dictated by the Dutch Search & Destroy policy, thus resulting in policy failure. METHODS: We performed a prospective case control study to determine risk factors for MUO acquisition/carriage (Dutch Trial Register: NTR2041). Cases were MUO carriers reported by participating medical microbiological laboratories to the RIVM from September 1st 2011 until September 1st 2013. Controls were randomly selected from the community during this period. RESULTS: Significant risk factors for MUO in logistic multivariate analysis were antibiotic use in the last twelve months, aOR 8.1 (5.6-11.7), screened as contact in a contact tracing but not detected as a MRSA carrier at that time, aOR 4.3 (2.1-8.8), having at least one foreign parent, aOR 2.4 (1.4-3.9) and receiving ambulatory care, aOR 2.3 (1.4-3.7). Our found risk factors explained 83% of the MUO carriage. CONCLUSIONS: Identifying new risk factors for MRSA carriers remains crucial for countries that apply a targeted screening approach as a Search and Destroy policy or as vertical infection prevention measure. PMID- 29190732 TI - Xuezhikang, an extract from red yeast rice, attenuates vulnerable plaque progression by suppressing endoplasmic reticulum stress-mediated apoptosis and inflammation. AB - Xuezhikang (XZK), an extract of red yeast rice, is a traditional Chinese medicine widely used for the treatment of cardiovascular diseases in China and other countries. However, whether XZK treatment can improve atherosclerotic plaque stability is not fully understood. Based on our previously developed mouse model of spontaneous vulnerable plaque formation and rupture in carotid arteries in ApoE-/- mice. We showed that low-dose (600 mg/kg/d) XZK improved plaque stability without decreasing plaque area, whereas high-dose (1200 mg/kg/d) XZK dramatically inhibited vulnerable plaque progression accompanied by decreased plaque area. Mechanistically, XZK significantly suppressed lesional endoplasmic reticulum (ER) stress in mouse carotid arteries. In vitro, XZK inhibited 7-KC-induced activation of ER stress in RAW264.7 macrophages, as assessed by the reduced levels of p PERK, p-IRE1alpha, p-eIF2alpha, c-ATF6, s-XBP1, and CHOP. Compared to controls, the XZK-treated group displayed dramatically decreased apoptotic cell numbers (shown by decreased TUNEL- and cleaved caspase3-positive cells), lower necrotic core area and ratio, and reduced expression of NF-kappaB target gene. In RAW264.7 cells, XZK inhibited 7-KC-induced upregulation of apoptosis, protein expression of apoptotic markers (cleaved caspase-3 and cleaved PARP), and NF-kappaB activation (shown by target gene transcription and IkappaBalpha reduction). Collectively, our results suggest that XZK effectively suppresses vulnerable plaque progression and rupture by mitigating macrophage ER stress and consequently inhibiting apoptosis and the NF-kappaB pro-inflammatory pathway, thereby providing an alternative therapeutic strategy for stabilizing atherosclerotic plaques.

PMID- 29190734 TI - A novel Porphyromonas gingivalis enzyme: An atypical dipeptidyl peptidase III with an ARM repeat domain. AB - Porphyromonas gingivalis, an asaccharolytic Gram-negative oral anaerobe, is a major pathogen associated with adult periodontitis, a chronic infective disease that a significant percentage of the human population suffers from. It preferentially utilizes dipeptides as its carbon source, suggesting the importance of dipeptidyl peptidase (DPP) types of enzyme for its growth. Until now DPP IV, DPP5, 7 and 11 have been extensively investigated. Here, we report the characterization of DPP III using molecular biology, biochemical, biophysical and computational chemistry methods. In addition to the expected evolutionarily conserved regions of all DPP III family members, PgDPP III possesses a C-terminal extension containing an Armadillo (ARM) type fold similar to the AlkD family of bacterial DNA glycosylases, implicating it in alkylation repair functions. However, complementation assays in a DNA repair-deficient Escherichia coli strain indicated the absence of alkylation repair function for PgDPP III. Biochemical analyses of recombinant PgDPP III revealed activity similar to that of DPP III from Bacteroides thetaiotaomicron, and in the range between activities of human and yeast counterparts. However, the catalytic efficiency of the separately expressed DPP III domain is ~1000-fold weaker. The structure and dynamics of the ligand-free enzyme and its complex with two different diarginyl arylamide substrates was investigated using small angle X-ray scattering, homology modeling, MD simulations and hydrogen/deuterium exchange (HDX). The correlation between the experimental HDX and MD data improved with simulation time, suggesting that the DPP III domain adopts a semi-closed or closed form in solution, similar to that reported for human DPP III. The obtained results reveal an atypical DPP III with increased structural complexity: its superhelical C terminal domain contributes to peptidase activity and influences DPP III interdomain dynamics. Overall, this research reveals multifunctionality of PgDPP III and opens direction for future research of DPP III family proteins. PMID- 29190735 TI - Subgroup analysis of continuous renal replacement therapy in severely burned patients. AB - Continuous renal replacement therapy (CRRT) is administered to critically ill patients with renal injuries as renal replacement or renal support. We aimed to identify predictors of mortality among burn patients receiving CRRT, and to investigate clinical differences according to acute kidney injury (AKI) status. This retrospective observational study evaluated 216 Korean burn patients who received CRRT at a burn intensive care unit. Patients were categorized by AKI status. Data were collected regarding arterial pH, laboratory results, ratio of arterial oxygen partial pressure to fractional inspired oxygen (PF ratio), and urine production. Among surviving patients, CRRT duration and the sequential organ failure assessment score were 6.5 days and 4.7 in the non-AKI group and 23.4 days and 7.4 in the AKI group, respectively (p = 0.003 and p = 0.008). On logistic regression analyses, mortality was significantly associated with a pH of <7.2 (p = 0.004), potassium levels of >5.0 mEg/L (p = 0.045), creatinine levels of >2.0 mg/dL (p = 0.011), lactate levels of >2 mmol/L (p<0.001), a PF ratio of <200 (p = 0.042), and a platelet count of <100,000/MUL (p<0.001). In the AKI group, poor outcomes were associated with a pH of <7.2, potassium levels of <5.0 mEg/L, lactate levels of >2 mmol/L, and a platelet count of <100,000/MUL, while good outcomes were associated with creatinine levels of >2 mg/dL. In the non-AKI group, poor outcomes were associated with lactate levels of >1.5 mmol/L, a PF ratio of <200, and a platelet count of <100,000/MUL, while good outcomes were associated with creatinine levels of >1.2 mg/dL. Duration of the CRRT application and the requirement for either renal replacement or renal support at the initiation of CRRT application are important considerations depending on its application. PMID- 29190736 TI - Humoral immune response against two surface antigens of Chlamydia pecorum in vaccinated and naturally infected sheep. AB - Chlamydia pecorum is a globally recognised livestock pathogen due to the significant clinical and economic impact it poses to livestock producers. Routine serological diagnosis is through a complement fixation test (CFT), which is often criticised for cross-reactivity, poor sensitivity and specificity. Although serology remains the preferred method in veterinary diagnostic laboratories, serological assays based on surface antigens of C. pecorum have not been established until now. In this study, we evaluated the use of two chlamydial recombinant protein antigens (PmpG and MOMP-G) by a direct IgG ELISA method for detection of ovine anti-chlamydial antibodies. Using the Pepscan method we then identified B cell epitopes across PmpG and MOMP-G proteins, in lambs with (a) naturally occurring asymptomatic C. pecorum infections (b) C. pecorum-associated polyarthritis and (c) recombinant PmpG and MOMP-G vaccine. Plasma IgG antibodies to PmpG in natural infection of lambs were detected earlier in infection than CFT and served as an acute phase marker. Antibodies to MOMP-G IgG were significantly heightened in lambs with C. pecorum-associated polyarthritis. PmpG and MOMP-G specific B-cell epitope mapping revealed epitope responses in immunised lambs cluster with some of the epitope responses in naturally infected lambs. B-cell epitope mapping further revealed that lambs with polyarthritis recognised several unique PmpG (50% frequency, peptide 8, 25, 40, 41 and 50) and MOMP (50% frequency, peptide 50) epitopes in comparison to asymptomatic infections. The findings of this study will have implications towards improved serodiagnosis of C. pecorum infections in livestock and inform the downstream development of alternative peptide-based antigens for future C. pecorum vaccine studies. PMID- 29190737 TI - A short feature vector for image matching: The Log-Polar Magnitude feature descriptor. AB - The choice of an optimal feature detector-descriptor combination for image matching often depends on the application and the image type. In this paper, we propose the Log-Polar Magnitude feature descriptor-a rotation, scale, and illumination invariant descriptor that achieves comparable performance to SIFT on a large variety of image registration problems but with much shorter feature vectors. The descriptor is based on the Log-Polar Transform followed by a Fourier Transform and selection of the magnitude spectrum components. Selecting different frequency components allows optimizing for image patterns specific for a particular application. In addition, by relying only on coordinates of the found features and (optionally) feature sizes our descriptor is completely detector independent. We propose 48- or 56-long feature vectors that potentially can be shortened even further depending on the application. Shorter feature vectors result in better memory usage and faster matching. This combined with the fact that the descriptor does not require a time-consuming feature orientation estimation (the rotation invariance is achieved solely by using the magnitude spectrum of the Log-Polar Transform) makes it particularly attractive to applications with limited hardware capacity. Evaluation is performed on the standard Oxford dataset and two different microscopy datasets; one with fluorescence and one with transmission electron microscopy images. Our method performs better than SURF and comparable to SIFT on the Oxford dataset, and better than SIFT on both microscopy datasets indicating that it is particularly useful in applications with microscopy images. PMID- 29190738 TI - Cervical HSV-2 infection causes cervical remodeling and increases risk for ascending infection and preterm birth. AB - Preterm birth (PTB), or birth before 37 weeks gestation, is the leading cause of neonatal mortality worldwide. Cervical viral infections have been established as risk factors for PTB in women, although the mechanism leading to increased risk is unknown. Using a mouse model of pregnancy, we determined that intra-vaginal HSV2 infection caused increased rates of preterm birth following an intra-vaginal bacterial infection. HSV2 infection resulted in histological changes in the cervix mimicking cervical ripening, including significant collagen remodeling and increased hyaluronic acid synthesis. Viral infection also caused aberrant expression of estrogen and progesterone receptor in the cervical epithelium. Further analysis using human ectocervical cells demonstrated a role for Src kinase in virus-mediated changes in estrogen receptor and hyaluronic acid expression. In conclusion, HSV2 affects proteins involved in tissue hormone responsiveness, causes significant changes reminiscent of premature cervical ripening, and increases risk of preterm birth. Studies such as this improve our chances of identifying clinical interventions in the future. PMID- 29190739 TI - Anthelminthic activity of glibenclamide on secondary cystic echinococcosis in mice. AB - Cystic echinococcosis (CE) is a worldwide parasitic zoonosis caused by the larval stage of Echinococcus granulosus. Current chemotherapy against this disease is based on the administration of benzimidazoles (BZMs). However, BZM treatment has a low cure rate and causes several side effects. Therefore, new treatment options are needed. The antidiabetic drug glibenclamide (Glb) is a second-generation sulfonylurea receptor inhibitor that has been shown to be active against protozoan parasites. Hence, we assessed the in vitro and in vivo pharmacological effects of Glb against the larval stage of E. granulosus. The in vitro activity was concentration dependent on both protoscoleces and metacestodes. Moreover, Glb combined with the minimum effective concentration of albendazole sulfoxide (ABZSO) was demonstrated to have a greater effect on metacestodes in comparison with each drug alone. Likewise, there was a reduction in the cyst weight after oral administration of Glb to infected mice (5 mg/kg of body weight administered daily for a period of 8 weeks). However, in contrast to in vitro assays, no differences in effectiveness were found between Glb + albendazole (ABZ) combined treatment and Glb monotherapy. Our results also revealed mitochondrial membrane depolarization and an increase in intracellular Ca2+ levels in Glb-treated protoscoleces. In addition, the intracystic drug accumulation and our bioinformatic analysis using the available E. granulosus genome suggest the presence of genes encoding sulfonylurea transporters in the parasite. Our data clearly demonstrated an anti-echinococcal effect of Glb on E. granulosus larval stage. Further studies are needed in order to thoroughly investigate the mechanism involved in the therapeutic response of the parasite to this sulfonylurea. PMID- 29190740 TI - Correlation of serum cytokines, chemokines, growth factors and enzymes with periodontal disease parameters. AB - BACKGROUND: Periodontal disease (PD) is characterized by inflammatory tissue destruction in tooth supporting apparatus. Many studies indicate that the underlying pathogenesis is in concordance with rheumatoid arthritis (RA) sharing immune-inflammatory events affect both diseases. The aim of this study was to investigate serum cytokines, chemokines, growth factors, enzymes and costimulatory proteins in association with periodontal conditions in PD and RA subjects. MATERIALS & METHODS: Periodontal examination was performed in RA (n = 38), PD (n = 38) and healthy subjects (n = 14). Bleeding on probing (BOP) and probing pocket depth (PPD) were measured. Marginal bone loss (MBL) for premolars and molars was measured on digital panoramic radiographs. PD was defined as present if the PPD was >=5mm in >= 3 different sites. Serum samples were collected from all subjects. A multiplex proximity extension assay (PEA) was used to analyze the samples for simultaneous measurement of 92 cytokines. Cytokines with >= 60% quantitative results were included. RESULTS: A significant positive correlation was seen for ST1A1, FGF-19 and NT-3 whereas EN-RAGE, DNER, CX3CL1 and TWEAK associated inversely with BOP, PPD>= 5mm and MBL but positively with number of teeth. Several CD markers (CD244, CD40, CDCP1, LIF-R, IL-10RA, CD5 and CD6) were found to be associated with BOP, shallow and deep pockets, MBL and number of teeth, either directly or inversely. Most chemokines (CCL8, CX3CL1, CXCL10, CXCL11, CCL11, CCL4, CCL20, CXCL5, CXCL6, and CCL23) were positively associated with number of teeth and some inversely related to MBL (CCL8, CXCL10). Proteins with enzymatic activity (ST1A1, HGF and CASP-8) were directly related to the severity of periodontal conditions and inversely related to number of teeth. Aside from FGF-19, other growth factors were also directly associated with MBL (HGF), number of teeth (VEGF-A, LAP TGF-beta-1) and, inversely to, shallow pockets (LAP TGF-beta-1, TGFA and Beta-NGF). Out of 33 cytokines, 32 associated inversely with shallow pockets, whereas only CD40 associated positively. Associations between cytokines and periodontal parameters in the RA group were comparatively less. Statistical analyses were adjusted for multivariate effects using the Benjamini-Hochberg false discovery rate method. CONCLUSION: Systemic inflammatory burden, via known and novel markers, is associated with periodontal conditions in PD and RA subjects. Shallow pockets are not associated with a higher inflammatory state. PMID- 29190741 TI - Preoperative transcranial direct current stimulation: Exploration of a novel strategy to enhance neuroplasticity before surgery to control postoperative pain. A randomized sham-controlled study. AB - BACKGROUND: An imbalance in the excitatory/inhibitory systems in the pain networks may explain the persistent chronic pain after hallux valgus surgery. Thus, to contra-regulate this dysfunction, the use of transcranial direct current stimulation (tDCS) becomes attractive. OBJECTIVE: We tested the hypothesis that two preoperative active(a)-tDCS sessions compared with sham(s)-tDCS could improve the postoperative pain [as indexed by Visual Analogue Scale (VAS) at rest and during walking (primary outcomes)]. To assess their effect on the change in the Numerical Pain Scale (NPS0-10) during Conditioned Pain Modulation (CPM-task), disability related to pain (DRP) and analgesic consumption (secondary outcomes). Also, we assessed if the brain derived neurotrophic factor (BDNF) in the cerebral spinal fluid (CSF) after tDCS could predict the intervention's effect on the DRP. METHODS: It is a prospective, double blind, sham-controlled, randomized single center, 40 women (18-70 years-old) who had undergone hallux valgus surgery were randomized to receive two sessions (20 minutes each) of anodal a-tDCS or s-tDCS on the primary motor cortex at night and in the morning before the surgery. To assess the DRP was used the Brazilian Profile of Chronic Pain: Screen (B-PCP:S). RESULTS: A-tDCS group showed lower scores on VAS at rest and during walking (P<0.001). At rest, the difference between groups was 2.13cm (95%CI = 1.59 to 2.68) while during walking was 1.67cm (95%CI = 1.05 to 2.28). A-tDCS, when compared to s-tDCS reduced analgesic doses in 73.25% (P<0.001), produced a greater reduction in B-PCP:S (mean difference of 9.41 points, 95%CI = 0.63 to 18.21) and higher function of descending pain modulatory system (DPMS) during CPM task. CONCLUSION: A-tDCS improves postoperative pain, the DRP and the function of DPMS. Also, the CSF BDNF after a-tDCS predicted the improvement in the DRP. In overall, these findings suggest that a-tDCS effects may be mediated by top-down regulatory mechanisms associated with the inhibitory cortical control. TRIAL REGISTRATION: ClinicalTrials.gov NCT02360462. PMID- 29190742 TI - Effect of nursing care hours on the outcomes of Intensive Care assistance. AB - OBJECTIVES: To correlate the average number of nursing care hours dedicated to Intensive Care Unit (ICU) patients with nursing care indicators. METHOD: Transverse, descriptive study conducted between 2011 and 2013. Data were obtained from the electronic records system and from the nursing staff daily schedule. Generalized Linear Models were used for analysis. RESULTS: A total of 1,717 patients were included in the study. The average NAS (Nursing Activities Score) value was 54.87. The average ratio between the number of nursing care hours provided to the patient and the number of nursing care hours required by the patient (hours ratio) was 0.87. Analysis of the correlation between nursing care indicators and the hours ratio showed that the indicators phlebitis and ventilator-associated pneumonia significantly correlated with hours ratio; that is, the higher the hours ratio, the lower the incidence of phlebitis and ventilator-associated pneumonia. CONCLUSION: The number of nursing care hours directly impacts patient outcomes, which makes adjustment of nurse staffing levels essential. PMID- 29190743 TI - Crystal structure of a tripartite complex between C3dg, C-terminal domains of factor H and OspE of Borrelia burgdorferi. AB - Complement is an important part of innate immunity. The alternative pathway of complement is activated when the main opsonin, C3b coats non-protected surfaces leading to opsonisation, phagocytosis and cell lysis. The alternative pathway is tightly controlled to prevent autoactivation towards host cells. The main regulator of the alternative pathway is factor H (FH), a soluble glycoprotein that terminates complement activation in multiple ways. FH recognizes host cell surfaces via domains 19-20 (FH19-20). All microbes including Borrelia burgdorferi, the causative agent of Lyme borreliosis, must evade complement activation to allow the infectious agent to survive in its host. One major mechanism that Borrelia uses is to recruit FH from host. Several outer surface proteins (Osp) have been described to bind FH via the C-terminus, and OspE is one of them. Here we report the structure of the tripartite complex formed by OspE, FH19-20 and C3dg at 3.18 A, showing that OspE and C3dg can bind simultaneously to FH19-20. This verifies that FH19-20 interacts via the "common microbial binding site" on domain 20 with OspE and simultaneously and independently via domain 19 with C3dg. The spatial organization of the tripartite complex explains how OspE on the bacterial surface binds FH19-20, leaving FH fully available to protect the bacteria against complement. Additionally, formation of tripartite complex between FH, microbial protein and C3dg might enable enhanced protection, particularly on those regions on the bacteria where previous complement activation led to deposition of C3d. This might be especially important for slow growing bacteria that cause chronic disease like Borrelia burgdorferi.

AB - BACKGROUND: Prevalence of metabolic syndrome (MS) and vitamin D deficiency was reported among postmenopausal women (PMW) in India. However, no report is available regarding the association of MS and 25-hydroxyvitamin D [25(OH)D] among PMW in India. This study aimed to find out the prevalence of MS and 25(OH)D status as well as their association among rural PMW of West Bengal, India. MATERIALS AND METHODS: This cross-sectional study was conducted among 222 randomly selected rural PMW in Singur Block, West Bengal, India. Serum 25(OH)D, Blood pressure (BP), waist circumference (WC), fasting blood glucose (FBG), triglycerides (TG) and high density lipoprotein cholesterol (HDL-C) were measured using standard procedures. MS was defined as per International Diabetes Federation, 2005 (for Asian-Indians) criteria. Statistical tests were done using SPSS software. RESULTS: Prevalence of metabolic syndrome was 46%. 51% and 19% PMW were vitamin D insufficient and deficient, respectively. 22% and 53% women having MS were vitamin D insufficient and deficient, respectively. Among the PMW, 21% and 47% with WC>=80cm; 22% and 62% with FBG>=110mg/dl; 21% and 54% with TG>=150mg/dl; 23% and 51% with HDL-C<50mg/dl, 15% and 55% with BP>=130/85mm of Hg were vitamin D insufficient and deficient, respectively. Significant statistical association between FBG and 25(OH)D status existed (p = 0.01). Significant positive correlation between WC and 25(OH)D level (p = 0.004) and significant negative correlation between FBG and 25(OH)D level observed (p = 0.02). WC was the only statistically significant predictor of the dependent variable. Odds of non-sufficient 25(OH)D level increased with decrease in WC. CONCLUSION: High prevalence of MS as well as vitamin D insufficiency and deficiency existed among PMW of Singur block, West Bengal, India. 25(OH)D had significant inverse and direct relationship with FBG and WC. Low 25(OH)D may be one of the potential risk factors for developing MS in PMW or vice-versa.

AB - Necrotizing enterocolitis (NEC) is a significant cause of morbidity and mortality in premature infants; yet its pathogenesis remains poorly understood. To evaluate the role of intestinal bacteria in protection against NEC, we assessed the ability of naturally occurring intestinal colonizer E. coli EC25 to influence composition of intestinal microbiota and NEC pathology in the neonatal rat model. Experimental NEC was induced in neonatal rats by formula feeding/hypoxia, and graded histologically. Bacterial populations were characterized by plating on blood agar, scoring colony classes, and identifying each class by sequencing 16S rDNA. Binding of bacteria to, and induction of apoptosis in IEC-6 enterocytes were examined by plating on blood agar and fluorescent staining for fragmented DNA. E. coli EC 25, which was originally isolated from healthy rats, efficiently colonized the intestine and protected from NEC following introduction to newborn rats with formula at 106 or 108 cfu. Protection did not depend significantly on EC25 inoculum size or load in the intestine, but positively correlated with the fraction of EC25 in the microbiome. Introduction of EC25 did not prevent colonization with other bacteria and did not significantly alter bacterial diversity. EC25 neither induced cultured enterocyte apoptosis, nor protected from apoptosis induced by an enteropathogenic strain of Cronobacter muytjensii. Our results show that E. coli EC25 is a commensal strain that efficiently colonizes the neonatal intestine and protects from NEC. PMID- 29190747 TI - Characterizing the heterogeneity of tumor tissues from spatially resolved molecular measures. AB - BACKGROUND: Tumor heterogeneity can manifest itself by sub-populations of cells having distinct phenotypic profiles expressed as diverse molecular, morphological and spatial distributions. This inherent heterogeneity poses challenges in terms of diagnosis, prognosis and efficient treatment. Consequently, tools and techniques are being developed to properly characterize and quantify tumor heterogeneity. Multiplexed immunofluorescence (MxIF) is one such technology that offers molecular insight into both inter-individual and intratumor heterogeneity. It enables the quantification of both the concentration and spatial distribution of 60+ proteins across a tissue section. Upon bioimage processing, protein expression data can be generated for each cell from a tissue field of view. RESULTS: The Multi-Omics Heterogeneity Analysis (MOHA) tool was developed to compute tissue heterogeneity metrics from MxIF spatially resolved tissue imaging data. This technique computes the molecular state of each cell in a sample based on a pathway or gene set. Spatial states are then computed based on the spatial arrangements of the cells as distinguished by their respective molecular states. MOHA computes tissue heterogeneity metrics from the distributions of these molecular and spatially defined states. A colorectal cancer cohort of approximately 700 subjects with MxIF data is presented to demonstrate the MOHA methodology. Within this dataset, statistically significant correlations were found between the intratumor AKT pathway state diversity and cancer stage and histological tumor grade. Furthermore, intratumor spatial diversity metrics were found to correlate with cancer recurrence. CONCLUSIONS: MOHA provides a simple and robust approach to characterize molecular and spatial heterogeneity of tissues. Research projects that generate spatially resolved tissue imaging data can take full advantage of this useful technique. The MOHA algorithm is implemented as a freely available R script (see supplementary information).

AB - BACKGROUND & AIMS: Aryl hydrocarbon Receptor Nuclear Translocator (ARNT) and its partners hypoxia-inducible factors (HIF)-1alpha and HIF-2alpha are candidate factors for the well-known link between the liver, metabolic dysfunction and elevation in circulating lipids and glucose. Methods: Hepatocyte-specific ARNT null (LARNT), HIF-1alpha-null (LHIF1alpha) and HIF-2alpha-null (LHIF2alpha) mice were created. RESULTS: LARNT mice had increased fasting glucose, impaired glucose tolerance, increased glucose production, raised post-prandial serum triglycerides (TG) and markedly lower hepatic ATP versus littermate controls. There was increased expression of G6Pase, Chrebp, Fas and Scd-1 mRNAs in LARNT animals. Surprisingly, LHIF1alpha and LHIF2alpha mice exhibited no alterations in any metabolic parameter assessed. CONCLUSIONS: These results provide convincing evidence that reduced hepatic ARNT can contribute to inappropriate hepatic glucose production and post-prandial dyslipidaemia. Hepatic ARNT may be a novel therapeutic target for improving post-prandial hypertriglyceridemia and glucose homeostasis. PMID- 29190748 TI - Low hepatitis C antibody screening rates among an insured population of Tennessean Baby Boomers. AB - INTRODUCTION: Chronic Hepatitis C Virus (HCV) infection is common and can cause liver disease and death. Persons born from 1945 through 1965 ("Baby Boomers") have relatively high prevalence of chronic HCV infection, prompting recommendations that all Baby Boomers be screened for HCV. If chronic HCV is confirmed, evaluation for antiviral treatment should be performed. Direct-acting antivirals can cure more than 90% of people with chronic HCV. This sequence of services can be referred to as the HCV "cascade of cure" (CoC). The Tennessee (TN) Department of Health (TDH) and a health insurer with presence in TN aimed to determine the proportion of Baby Boomers who access HCV screening services and appropriately navigate the HCV CoC in TN. METHODS: TDH surveillance data and insurance claim records were queried to identify the cohort of Baby Boomers eligible for HCV testing. Billing codes and pharmacy records from 2013 through 2015 were used to determine whether HCV screening and other HCV-related services were provided. The proportion of individuals accessing HCV screening and other steps along the HCV CoC was determined. Multivariable analyses were performed to identify factors associated with HCV screening and treatment. RESULTS: Among 501,388 insured Tennessean Baby Boomers, 7% were screened for HCV. Of the 40,019 who received any HCV-related service, 86% were screened with an HCV antibody test, 20% had a confirmatory HCV PCR, 9% were evaluated for treatment, and 4% were prescribed antivirals. Hispanics were more likely to be screened and treated for HCV than non-Hispanic whites. HCV screening was more likely to occur in the Nashville-Davidson region than in other regions of TN, but there were regional variations in HCV treatment. CONCLUSIONS: Many insured Tennessean Baby Boomers do not access HCV screening services, despite national recommendations. Demographic and regional differences in uptake along the HCV CoC should inform public health interventions aimed at mitigating the effects of chronic HCV. PMID- 29190749 TI - Physiological and fitness differences between cytotypes vary with stress in a grassland perennial herb. AB - BACKGROUND AND AIMS: Understanding the consequences of polyploidization is a major step towards assessing the importance of this mode of speciation. Most previous studies comparing different cytotypes, however, did so only within a single environment and considered only one group of traits. To take a step further, we need to explore multiple environments and a wide range of traits. The aim of this study was to assess response of diploid and autotetraploid individuals of Knautia arvensis (Dipsacaceae) to two stress conditions, shade or drought. METHODS: We studied eleven photosynthetic, morphological and fitness parameters of the plants over three years in a common garden under ambient conditions and two types of stress. KEY RESULTS: The results indicate strong differences in performance and physiology between cytotypes in ambient conditions. Interestingly, higher fitness in diploids contrasted with more efficient photosynthesis in tetraploids in ambient conditions. However, stress, especially drought, strongly reduced fitness and disrupted function of the photosystems in both cytotypes reducing the between cytotype differences. The results indicate that drought stress reduced function of the photosynthetic processes in both cytotypes but particularly in tetraploids, while fitness reduction was stronger in diploids. CONCLUSIONS: The photosynthesis related traits show higher plasticity in polyploids as theoretically expected, while the fitness related traits show higher plasticity in diploids especially in response to drought. This suggests that between cytotype comparisons need to consider multiple traits and multiple environments to understand the breath of possible responses of different cytotypes to stress. They also show that integrating results based on different traits is not straightforward and call for better mechanistic understanding of the relationships between species photosynthetic activity and fitness. Still, considering multiple environments and multiple species traits is crucial for understanding the drivers of niche differentiation between cytotypes in future studies. PMID- 29190750 TI - The joint effect of personality traits and perceived stress on pedestrian behavior in a Chinese sample. AB - While improper pedestrian behavior has become an important factor related to road traffic fatalities, especially in developing countries, the effects of personality traits and/or stress on pedestrian behavior have been rarely reported. The current study explored the joint effects of five personality traits (i.e., extraversion, openness, neuroticism, normlessness and altruism) and global perceived stress (measured with the Perceived Stress Scale-10) on pedestrian behavior (measured with the Pedestrian Behavior Scale) in 311 Chinese individuals. Results showed that altruism, neuroticism and openness significantly affected different pedestrian behavior dimensions, while global perceived stress also significantly and positively predicted positive behavior. Moreover, the effect of neuroticism on positive behavior was fully mediated by stress. Some explanations and implications are provided in the discussion section. PMID- 29190751 TI - Acute effect of dietary nitrate on forearm muscle oxygenation, blood volume and strength in older adults: A randomized clinical trial. AB - Both recovery time of post-exercise muscle oxygenation and muscle strength decline with aging. Although beetroot consumption has been shown to improve muscle oxygenation and exercise performance in adults, these effects in the elderly has not been addressed. The aim of the present study was to evaluate the effect of a beetroot-based gel (BG) on muscle O2 saturation, blood volume (tHb) and handgrip strength in the elderly in response to handgrip exercise. In a randomized crossover double-blind design, twelve older subjects consumed BG (100 g of beetroot-based gel containing ~ 12 mmol nitrate) or PLA (100 g of nitrate depleted gel nitrate-depleted). The subjects performed a rhythmic handgrip exercise which consisted of a one 1-min set at 30% of the maximal voluntary contraction (MVC) of each subject, followed by a 1 min recovery. The muscle oxygenation parameters and tHb were continuously monitored by using near-infrared spectroscopy. MVC was evaluated at baseline, immediately after exercise, and 30 min afterwards. The muscle O2 resaturation rate during exercise recovery was greater in the BG when compared to PLA condition (1.43 +/- 0.77 vs 1.02 +/- 0.48%.s-1; P < 0.05). Significant increase was observed in tHb during exercise recovery (10.25 +/- 5.47 vs 6.72 +/- 4.55 MUM; P < 0.05) and significant reduction of handgrip strength decline was observed 30 min after exercise in BG ( 0.24 +/- 0.18 vs-0.39 +/- 0.20 N; P < 0.05). In summary, a single dose of a beetroot-based gel speeds up muscle O2 resaturation, increases blood volume and improves recovery of handgrip strength after handgrip exercise in older adults. PMID- 29190753 TI - Children and young people's perceptions of energy drinks: A qualitative study. AB - BACKGROUND: Consumption of soft drinks is declining in many countries, yet energy drink sales continue to increase, particularly amongst young consumers. Little is currently known about the drivers behind these trends. Energy drinks are high in sugar and caffeine, and evidence indicates that regular or heavy use by under 18s is likely to be detrimental to health. This study aimed to explore children and young people's attitudes and perceptions in relation to energy drinks in a UK context. METHODS: Eight focus groups were conducted with pupils aged 10-11 years (n = 20) and 13-14 years (n = 17) from four schools in northern England. A sub sample also took part in a mapping exercise to generate further insights. Data were analysed using the constant comparative approach. RESULTS: Energy drinks were reportedly consumed in a variety of public and private places, generally linked to social activities, sports and computer gaming (particularly amongst boys). Participants demonstrated strong brand awareness and preferences that were linked to taste and perceived value for money. The relatively low price of energy drinks and their widespread availability were identified as key factors, along with gendered branding and marketing. Some participants demonstrated a critical approach to manufacturers' claims and many were keen to become better informed, often through school- or peer-based interventions. Other potential interventions included age restrictions, voluntary schemes involving retailers and improved labelling. CONCLUSIONS: The lack of a single dominant factor in participants' consumption choices suggests that there is unlikely to be a 'silver bullet' in attempting to address this issue. However, the findings provide support for policy-level interventions that seek to change the behaviours of manufacturers and retailers as well as consumers, and actively involve children and young people where possible. PMID- 29190752 TI - Differential transcriptome profiling of chilling stress response between shoots and rhizomes of Oryza longistaminata using RNA sequencing. AB - Rice (Oryza sativa) is very sensitive to chilling stress at seedling and reproductive stages, whereas wild rice, O. longistaminata, tolerates non-freezing cold temperatures and has overwintering ability. Elucidating the molecular mechanisms of chilling tolerance (CT) in O. longistaminata should thus provide a basis for rice CT improvement through molecular breeding. In this study, high throughput RNA sequencing was performed to profile global transcriptome alterations and crucial genes involved in response to long-term low temperature in O. longistaminata shoots and rhizomes subjected to 7 days of chilling stress. A total of 605 and 403 genes were respectively identified as up- and down regulated in O. longistaminata under 7 days of chilling stress, with 354 and 371 differentially expressed genes (DEGs) found exclusively in shoots and rhizomes, respectively. GO enrichment and KEGG pathway analyses revealed that multiple transcriptional regulatory pathways were enriched in commonly induced genes in both tissues; in contrast, only the photosynthesis pathway was prevalent in genes uniquely induced in shoots, whereas several key metabolic pathways and the programmed cell death process were enriched in genes induced only in rhizomes. Further analysis of these tissue-specific DEGs showed that the CBF/DREB1 regulon and other transcription factors (TFs), including AP2/EREBPs, MYBs, and WRKYs, were synergistically involved in transcriptional regulation of chilling stress response in shoots. Different sets of TFs, such as OsERF922, OsNAC9, OsWRKY25, and WRKY74, and eight genes encoding antioxidant enzymes were exclusively activated in rhizomes under long-term low-temperature treatment. Furthermore, several cis-regulatory elements, including the ICE1-binding site, the GATA element for phytochrome regulation, and the W-box for WRKY binding, were highly abundant in both tissues, confirming the involvement of multiple regulatory genes and complex networks in the transcriptional regulation of CT in O. longistaminata. Finally, most chilling-induced genes with alternative splicing exclusive to shoots were associated with photosynthesis and regulation of gene expression, while those enriched in rhizomes were primarily related to stress signal transduction; this indicates that tissue-specific transcriptional and post transcriptional regulation mechanisms synergistically contribute to O. longistaminata long-term CT. Our findings provide an overview of the complex regulatory networks of CT in O. longistaminata. PMID- 29190754 TI - Encryption of agonistic motifs for TLR4 into artificial antigens augmented the maturation of antigen-presenting cells. AB - Adjuvants are indispensable for achieving a sufficient immune response from vaccinations. From a functional viewpoint, adjuvants are classified into two categories: "physical adjuvants" increase the efficacy of antigen presentation by antigen-presenting cells (APC) and "signal adjuvants" induce the maturation of APC. Our previous study has demonstrated that a physical adjuvant can be encrypted into proteinous antigens by creating artificial proteins from combinatorial assemblages of epitope peptides and those peptide sequences having propensities to form certain protein structures (motif programming). However, the artificial antigens still require a signal adjuvant to maturate the APC; for example, co-administration of the Toll-like receptor 4 (TLR4) agonist monophosphoryl lipid A (MPLA) was required to induce an in vivo immunoreaction. In this study, we further modified the previous artificial antigens by appending the peptide motifs, which have been reported to have agonistic activity for TLR4, to create "adjuvant-free" antigens. The created antigens with triple TLR4 agonistic motifs in their C-terminus have activated NF-kappaB signaling pathways through TLR4. These proteins also induced the production of the inflammatory cytokine TNF-alpha, and the expression of the co-stimulatory molecule CD40 in APC, supporting the maturation of APC in vitro. Unexpectedly, these signal adjuvant-encrypted proteins have lost their ability to be physical adjuvants because they did not induce cytotoxic T lymphocytes (CTL) in vivo, while the parental proteins induced CTL. These results confirmed that the manifestation of a motif's function is context-dependent and simple addition does not always work for motif-programing. Further optimization of the molecular context of the TLR4 agonistic motifs in antigens should be required to create adjuvant-free antigens. PMID- 29190755 TI - Towards improving sterile insect technique: Exposure to orange oil compounds increases sexual signalling and longevity in Ceratitis capitata males of the Vienna 8 GSS. AB - The Mediterranean fruit fly (medfly), Ceratitis capitata, is a notorious insect pest causing huge economic losses worldwide. The sterile insect technique (SIT) is widely used for its control. Using sexually mature sterilized males of the Vienna 8 (tsl) strain in the laboratory, we explored whether exposure of males to citrus compounds (separately or in a mixture) affects their sexual behaviour and if nutritional conditions and age modulate those effects. Exposed males exhibited increased sexual signalling compared to unexposed ones, particularly when fed a rich adult diet. Interestingly, and for the first time reported in medfly, exposure of Vienna 8 males to a mixture of citrus compounds increases longevity under poor adult diet conditions. We discuss the possible associated mechanisms and provide some practical implications of our results towards improving the effectiveness of SIT. PMID- 29190756 TI - Visualizing the spatiotemporal map of Rac activation in bovine aortic endothelial cells under laminar and disturbed flows. AB - Disturbed flow can eliminate the alignment of endothelial cells in the direction of laminar flow, and significantly impacts on atherosclerosis in collateral arteries near the bifurcation and high curvature regions. While shear stress induced Rac polarity has been shown to play crucial roles in cell polarity and migration, little is known about the spatiotemporal map of Rac under disturbed flow, and the mechanism of flow-induced cell polarity still needs to be elucidated. In this paper, disturbed flow or laminar flow with 15 dyn/cm2 of average shear stress was applied on bovine aortic endothelial cells (BAECs) for 30 minutes. A genetically-encoded PAK-PBD-GFP reporter was transfected into BAECs to visualize the real-time activation of Rac in living cell under fluorescence microscope. The imaging of the fluorescence intensity was analyzed by Matlab and the normalized data was converted into 3D spatiotemporal map. Then the changes of data upon chemical interference were fitted with logistic curve to explore the rule and mechanism of Rac polarity under laminar or disturbed flow. A polarized Rac activation was observed at the downstream edge along the laminar flow, which was enhanced by benzol alcohol-enhanced membrane fluidity but inhibited by nocodazole-disrupted microtubules or cholesterol-inhibited membrane fluidity, while no obvious polarized Rac activation could be found upon disturbed flow application. It is concluded that disturbed flow inhibits the flow-induced Rac polarized activation, which is related to the interaction of cell membrane and cytoskeleton, especially the microtubules. PMID- 29190758 TI - The influence of anticipated pride and guilt on pro-environmental decision making. AB - The present research explores the relationship between anticipated emotions and pro-environmental decision making comparing two differently valenced emotions: anticipated pride and guilt. In an experimental design, we examined the causal effects of anticipated pride versus guilt on pro-environmental decision making and behavioral intentions by making anticipated emotions (i.e. pride and guilt) salient just prior to asking participants to make a series of environmental decisions. We find evidence that anticipating one's positive future emotional state from green action just prior to making an environmental decision leads to higher pro-environmental behavioral intentions compared to anticipating one's negative emotional state from inaction. This finding suggests a rethinking in the domain of environmental and climate change messaging, which has traditionally favored inducing negative emotions such as guilt to promote pro-environmental action. Furthermore, exploratory results comparing anticipated pride and guilt inductions to baseline behavior point toward a reactance eliciting effect of anticipated guilt. PMID- 29190757 TI - Long-lived weight-reduced alphaMUPA mice show higher and longer maternal dependent postnatal leptin surge. AB - We investigated whether long-lived weight-reduced alphaMUPA mice differ from their wild types in postnatal body composition and leptin level, and whether these differences are affected by maternal-borne factors. Newborn alphaMUPA and wild type mice had similar body weight and composition up to the third postnatal week, after which alphaMUPA mice maintained lower body weight due to lower fat free mass. Both strains showed a surge in leptin levels at the second postnatal week, initiating earlier in alphaMUPA mice, rising higher and lasting longer than in the wild types, mainly in females. Leptin level in dams' serum and breast milk, and in their pup's stomach content were also higher in alphaMUPA than in the WT during the surge peak. Leptin surge preceded the strain divergence in body weight, and was associated with an age-dependent decrease in the leptin:fat mass ratio-suggesting that postnatal sex and strain differences in leptin ontogeny are strongly influenced by processes independent of fat mass, such as production and secretion, and possibly outside fat tissues. Dam removal elevated corticosterone level in female pups from both strains similarly, yet mitigated the leptin surge only in alphaMUPA-eliminating the strain differences in leptin levels. Overall, our results indicate that alphaMUPA's postnatal leptin surge is more pronounced than in the wild type, more sensitive to maternal deprivation, less related to pup's total adiposity, and is associated with a lower post-weaning fat-free mass. These strain-related postnatal differences may be related to alphaMUPA's higher milk-borne leptin levels. Thus, our results support the use of alphaMUPA mice in future studies aimed to explore the relationship between maternal (i.e. milk borne) factors, postnatal leptin levels, and post-weaning body composition and energy homeostasis. PMID- 29190759 TI - Graph-based analysis of brain connectivity in schizophrenia. AB - The present study evaluated brain connectivity using electroencephalography (EEG) data from 14 patients with schizophrenia and 14 healthy controls. Phase-Locking Value (PLV), Phase-Lag Index (PLI) and Directed Transfer Function (DTF) were calculated for the original EEG data and following current source density (CSD) transformation, re-referencing using the average reference electrode (AVERAGE) and reference electrode standardization techniques (REST). The statistical analysis of adjacency matrices was carried out using indices based on graph theory. Both CSD and REST reduced the influence of volume conducted currents. The largest group differences in connectivity were observed for the alpha band. Schizophrenic patients showed reduced connectivity strength, as well as a lower clustering coefficient and shorter characteristic path length for both measures of phase synchronization following CSD transformation or REST re-referencing. Reduced synchronization was accompanied by increased directional flow from the occipital region for the alpha band. Following the REST re-referencing, the sources of alpha activity were located at parietal rather than occipital derivations. The results of PLV and DTF demonstrated group differences in fronto posterior asymmetry following CSD transformation, while for PLI the differences were significant only using REST. The only analysis that identified group differences in inter-hemispheric asymmetry was DTF calculated for REST. Our results suggest that a comparison of different connectivity measures using graph based indices for each frequency band, separately, may be a useful tool in the study of disconnectivity disorders such as schizophrenia. PMID- 29190760 TI - Simulated ocean acidification reveals winners and losers in coastal phytoplankton. AB - The oceans absorb ~25% of the annual anthropogenic CO2 emissions. This causes a shift in the marine carbonate chemistry termed ocean acidification (OA). OA is expected to influence metabolic processes in phytoplankton species but it is unclear how the combination of individual physiological changes alters the structure of entire phytoplankton communities. To investigate this, we deployed ten pelagic mesocosms (volume ~50 m3) for 113 days at the west coast of Sweden and simulated OA (pCO2 = 760 MUatm) in five of them while the other five served as controls (380 MUatm). We found: (1) Bulk chlorophyll a concentration and 10 out of 16 investigated phytoplankton groups were significantly and mostly positively affected by elevated CO2 concentrations. However, CO2 effects on abundance or biomass were generally subtle and present only during certain succession stages. (2) Some of the CO2-affected phytoplankton groups seemed to respond directly to altered carbonate chemistry (e.g. diatoms) while others (e.g. Synechococcus) were more likely to be indirectly affected through CO2 sensitive competitors or grazers. (3) Picoeukaryotic phytoplankton (0.2-2 MUm) showed the clearest and relatively strong positive CO2 responses during several succession stages. We attribute this not only to a CO2 fertilization of their photosynthetic apparatus but also to an increased nutrient competitiveness under acidified (i.e. low pH) conditions. The stimulating influence of high CO2/low pH on picoeukaryote abundance observed in this experiment is strikingly consistent with results from previous studies, suggesting that picoeukaryotes are among the winners in a future ocean. PMID- 29190761 TI - Acute glucoregulatory and vascular outcomes of three strategies for interrupting prolonged sitting time in postmenopausal women: A pilot, laboratory-based, randomized, controlled, 4-condition, 4-period crossover trial. AB - BACKGROUND: Prolonged sitting is associated with cardiometabolic and vascular disease. Despite emerging evidence regarding the acute health benefits of interrupting prolonged sitting time, the effectiveness of different modalities in older adults (who sit the most) is unclear. METHODS: In preparation for a future randomized controlled trial, we enrolled 10 sedentary, overweight or obese, postmenopausal women (mean age 66 years +/-9; mean body mass index 30.6 kg/m2 +/ 4.2) in a 4-condition, 4-period crossover feasibility pilot study in San Diego to test 3 different sitting interruption modalities designed to improve glucoregulatory and vascular outcomes compared to a prolonged sitting control condition. The interruption modalities included: a) 2 minutes standing every 20 minutes; b) 2 minutes walking every hour; and c) 10 minutes standing every hour. During each 5-hr condition, participants consumed two identical, standardized meals. Blood samples, blood pressure, and heart rate were collected every 30 minutes. Endothelial function of the superficial femoral artery was measured at baseline and end of each 5-hr condition using flow-mediated dilation (FMD). Participants completed each condition on separate days, in randomized order. This feasibility pilot study was not powered to detect statistically significant differences in the various outcomes, however, analytic methods (mixed models) were used to test statistical significance within the small sample size. RESULTS: Nine participants completed all 4 study visits, one participant completed 3 study visits and then was lost to follow up. Net incremental area under the curve (iAUC) values for postprandial plasma glucose and insulin during the 5-hr sitting interruption conditions were not significantly different compared to the control condition. Exploratory analyses revealed that the 2-minute standing every 20 minutes and the 2-minute walking every hour conditions were associated with a significantly lower glycemic response to the second meal compared to the first meal (i.e., condition-matched 2-hour post-lunch glucose iAUC was lower than 2 hour post-breakfast glucose iAUC) that withstood Bonferroni correction (p = 0.0024 and p = 0.0084, respectively). Using allometrically scaled data, the 10 minute standing every hour condition resulted in an improved FMD response, which was significantly greater than the control condition after Bonferroni correction (p = 0.0033). CONCLUSION: This study suggests that brief interruptions in prolonged sitting time have modality-specific glucoregulatory and vascular benefits and are feasible in an older adult population. Larger laboratory and real-world intervention studies of pragmatic and effective methods to change sitting habits are needed. TRIAL REGISTRATION: ClinicalTrials.gov NCT02743286. PMID- 29190762 TI - Comprehensive analysis of early fractional anisotropy changes in acute ischemic stroke. AB - BACKGROUND AND PURPOSE: Cerebral ischemia leads to a rapid decrease of the apparent diffusion coefficient. For fractional anisotropy both increase and decrease have been reported in acute ischemic stroke. Aim of this study was to characterize early water diffusion changes in a homogenous group of acute stroke patients and to clarify the issue of early fractional anisotropy changes and their relation to time from symptom onset. METHODS: MRI data of patients with acute ischemic stroke examined by diffusion tensor imaging within 8h after symptom were analyzed. We calculated fractional anisotropy, eigenvalues and the isotropic and anisotropic components of the diffusion tensor. The values were calculated as ratios between the ischemic lesion and a mirror region in the unaffected side and correlated with clinical parameters. RESULTS: We included 63 patients: 49% female, mean age 69 +/- 14 years, median NIHSS on admission 9 (IQR 4-14). For the whole sample, mean fractional anisotropy was increased (ratio: 1.083 +/- 0.168), while all other diffusion parameters were decreased. Both the isotropic and anisotropic component of the diffusion tensor were decreased with a more pronounced decrease of the isotropic component (ratios: isotropic = 0.730 +/ 0.106, anisotropic = 0.788 +/- 0.127; p<0.001). There was no correlation of fractional anisotropy with time from symptom onset. Looking at individual patients, fractional anisotropy was increased in 70%. There were no differences in clinical characteristics between patients with increased and decreased fractional anisotropy. CONCLUSION: Fractional anisotropy increase in acute stroke results from a more pronounced decrease of the isotropic diffusion component and is not related to time from symptom onset. Thus, fractional anisotropy is not helpful as a surrogate marker of lesion age in the very first hours of stroke. PMID- 29190763 TI - In vitro activity of Spirulina platensis water extract against different Candida species isolated from vulvo-vaginal candidiasis cases. AB - The high incidence of vulvo-vaginal candidiasis, combined with the growing problems about azole resistance and toxicity of antifungal drugs, highlights the need for the development of new effective strategies for the treatment of this condition. In this context, natural compounds represent promising alternatives. The cyanobacterium Spirulina platensis, a blue-green alga, exhibits antimicrobial activities against several microorganisms. Nevertheless, only few data about the antifungal properties of Spirulina platensis are available and its potential toxic effects have not been largely investigated. The aim of this study was to evaluate the in vitro activity of a fully-characterized water extract of Spirulina platensis against 22 strains of Candida spp. Prior to considering its potential topical use, we both investigated whether the extract exerted target activities on guinea pig uterine smooth muscle, and the impact of Spirulina platensis on the dominant microorganisms of the vaginal microbiota (i.e., lactobacilli), in order to exclude possible adverse events. By means of a broth microdilution assay, we found that the microalga extract possesses good antifungal properties (MIC: 0.125-0.5 mg/ml), against all the Candida species with a fungicidal activity. At the concentrations active against candida, Spirulina platensis did not modify the spontaneous basic waves pattern of uterine myometrium as underlined by the absence of aberrant contractions, and did not affect the main health-promoting bacteria of the vaginal ecosystem. Finally, we evaluated the selectivity index of our extract by testing its cytotoxicity on three different cell lines and it showed values ranging between 2 and 16. Further in vivo studies are needed, in particular to evaluate the use of control-release formulations in order to maintain Spirulina platensis concentrations at anti Candida active doses but below the toxic levels found in the present work. PMID- 29190764 TI - Selenium requirements based on muscle and kidney selenoprotein enzyme activity and transcript expression in the turkey poult (Meleagris gallopavo). AB - The current NRC selenium (Se) requirement for turkeys is 0.2 MUg Se/g diet. We previously fed turkey poults a Se-deficient diet (0.005 MUg Se/g) supplemented with 10 graded levels of Se (0, 0.025, 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, 0.75, 1.0 MUg Se/g as Na2SeO3, 5/treatment) for 4 wk, and found that the minimum dietary Se requirement was 0.3 MUg Se/g based on selenoprotein enzyme activity in blood, liver, gizzard and pancreas. Because the turkey is primarily a production animal, we expanded this analysis to kidney, heart, breast and thigh. Se concentrations in Se-deficient poults were 5.0, 9.8, 33, and 15% of levels in poults fed 0.4 MUg Se/g in liver, kidney, thigh and breast, respectively. Increasing Se supplementation resulted in hyperbolic response curves for all tissues; breakpoint analysis indicated minimum Se requirements of 0.34-0.36 MUg Se/g based on tissue Se levels in liver, kidney and thigh. Similarly, GPX1 activity in muscle tissues and kidney responded hyperbolically to increasing dietary Se, reaching well-defined plateaus with breakpoints at 0.30-0.36 MUg Se/g. Minimum Se requirements based on GPX4 activity were 0.30-0.32 MUg Se/g for breast and thigh. Selenoprotein transcript expression decreased significantly in Se deficiency for only 2, 3, 5, and 6 mRNA in breast, thigh, heart, and kidney, respectively, out of 24 known avian selenoproteins. Se response curves for regulated selenoprotein transcripts were hyperbolic, and reached well-defined plateaus with breakpoints in a narrow range of 0.08-0.19 MUg Se/g. No selenoprotein transcript was altered by supernutritional Se. In summary, these results clearly indicate that the NRC dietary Se requirement should be raised to 0.4 MUg Se/g, at least for poults, to meet the nutritional needs of the young turkey. The Se response curve plateaus further show that limits for turkey supplementation with selenite could safely be raised to 0.5 MUg Se/g diet.

AB - Traditionally, species of the genus Zinaida were assigned to the genus Polytremis, until molecular evidence revealed that the former is a distinct genus. Nine species in Polytremis sensu Evans have since been removed and assigned to Zinaida; however, there is still uncertainty as to the taxonomic status of an additional seven Polytremis species. Moreover, the interspecific relationships within Zinaida have remained unresolved. To further investigate the taxonomic statuses and interspecific relationships within Zinaida, a molecular phylogeny of most species of Zinaida and its allies was inferred based on regions of the mitochondrial COI-COII and 16S and nuclear EF-1alpha genes (3006 bp). The results revealed that Zinaida is monophyletic and consists of four intra-generic clades that correspond to morphological characteristics. Clade A (Z. suprema group) consists of P. kiraizana, Z. suprema, and P. gigantea, with the latter two as sister species. Clade B (Z. nascens group) consists of seven species, and is the sister group of Clade C (Z. pellucida group), which comprises sister species Z. pellucida and Z. zina. In Clade B, Z. caerulescens and Z. gotama, and Z. theca and Z. fukia are sister species, respectively. On the basis of our molecular evidence and morphological features, we have moved P. gigantea, P. kiraizana, P. jigongi, and P. micropunctata to the genus Zinaida as new combinations. We review morphological characteristics and discuss the distribution of each of these groups in the light of our phylogenetic hypothesis, and provide a comprehensive taxonomic checklist. PMID- 29190766 TI - Developmental peculiarities in placentae of ovine uniparental conceptuses. AB - Genomic imprinting is an epigenetic phenomenon regulating mono-allelic expression of genes depending on their parental origin. Defective genomic imprinting is involved in several placental disorders, such as intrauterine growth restriction and pre-eclampsia. Uniparental embryos, having maternal-only or paternal-only genomes (parthenogenotes [PAR] and androgenotes [AND], respectively), are useful models to study placentation. The aim of this work was to reveal the effect of parental genome (maternal and paternal) on placentation. To do this, uniparental (AND and PAR) and biparental (CTR) in vitro produced sheep embryos transferred to recipient females were collected at day 20 of pregnancy and their placentae were analyzed. qPCR analysis showed that imprinted genes (H19, IGF2R and DLK1) were expressed accordingly to their parental origin while the expression f DNA methyltransferases () was disregulated, especially in PAR (P < 0.05). AND placentae were significantly hypomethylated compared to both PAR and CTR (P = 0.023). Chorion-allantoid of AND showed impaired development of vessels and reduced mRNA expression of vasculogenetic factors (ANG2 P = 0.05; VEGFR2 P< 0.001; TIE2 P < 0.001). Morphologically, PAR placentae were characterized by abnormal structure of the trophoectodermal epithelium and reduced total number (P<0.03) of Trophoblastic Binucleate Cells. A reduced implantation rate of both classes of uniparental embryos (P<0.03) was also noted. Our results provide new insights into the characterization of uniparental embryos and demonstrate the complementary role of parental genomes for the correct establishment of pregnancy. Thus, our findings may suggest new targets to improve our understanding of the origin of imprinting-related placental dysfunction. PMID- 29190768 TI - Medical costs, Cesarean delivery rates, and length of stay in specialty hospitals vs. non-specialty hospitals in South Korea. AB - BACKGROUND: Since 2011, specialty hospitals in South Korea have been known for providing high- quality care in specific clinical areas. Much research related to specialty hospitals and their performance in many such areas has been performed, but investigations about their performance in obstetrics and gynecology are lacking. Thus, we aimed to compare specialty vs. non-specialty hospitals with respect to mode of obstetric delivery, especially the costs and length of stay related to Cesarean section (CS) procedures, and to provide evidence to policy makers for evaluating the success of hospitals that specialize in obstetric and gynecological (OBGYN) care. METHODS: We obtained National Health Insurance claim data from 2012 to 2014, which included information from 418,141 OBGYN cases at 214 hospitals. We used a generalized estimating equation model to identify a potential association between the likelihood of CS at specialty hospitals compared with other hospitals. We also evaluated medical costs and length of stay in specialty hospitals according to type of delivery. RESULTS: We found that 150,256 (35.9%) total deliveries were performed by CS. The odds ratio of CS was significantly lower in specialty hospitals (OR: 0.95, 95% CI: 0.93-0.96compared to other hospitals Medical costs (0.74%) and length of stay (1%) in CS cases increased in specialty hospitals, although length of stay following vaginal delivery was lower (0.57%) in specialty hospitals compared with other hospitals. CONCLUSIONS: We determined that specialty hospitals are significantly associated with a lower likelihood of CS delivery and shorter length of stay after vaginal delivery. Although they are also associated with higher costs for delivery, the increased cost could be due to the high level of intensive care provided, which leads to improve quality of care. Policy-makers should consider incentive programs to maintain performance of specialty hospitals and promote efficiency that could reduce medical costs accrued by patients. PMID- 29190767 TI - High DNA stability in white blood cells and buffy coat lysates stored at ambient temperature under anoxic and anhydrous atmosphere. AB - Conventional storage of blood-derived fractions relies on cold. However, lately, ambient temperature preservation has been evaluated by several independent institutions that see economic and logistic advantages in getting rid of the cold chain. Here we validated a novel procedure for ambient temperature preservation of DNA in white blood cell and buffy coat lysates based on the confinement of the desiccated biospecimens under anoxic and anhydrous atmosphere in original hermetic minicapsules. For this validation we stored encapsulated samples either at ambient temperature or at several elevated temperatures to accelerate aging. We found that DNA extracted from stored samples was of good quality with a yield of extraction as expected. Degradation rates were estimated from the average fragment size of denatured DNA run on agarose gels and from qPCR reactions. At ambient temperature, these rates were too low to be measured but the degradation rate dependence on temperature followed Arrhenius' law, making it possible to extrapolate degradation rates at 25 degrees C. According to these values, the DNA stored in the encapsulated blood products would remain larger than 20 kb after one century at ambient temperature. At last, qPCR experiments demonstrated the compatibility of extracted DNA with routine DNA downstream analyses. Altogether, these results showed that this novel storage method provides an adequate environment for ambient temperature long term storage of high molecular weight DNA in dehydrated lysates of white blood cells and buffy coats. PMID- 29190769 TI - Measuring couple relationship quality in a rural African population: Validation of a Couple Functionality Assessment Tool in Malawi. AB - Available data suggest that individual and family well-being are linked to the quality of women's and men's couple relationships, but few tools exist to assess couple relationship functioning in low- and middle-income countries. In response to this gap, Catholic Relief Services has developed a Couple Functionality Assessment Tool (CFAT) to capture valid and reliable data on various domains of relationship quality. This tool is designed to be used by interventions which aim to improve couple and family well-being as a means of measuring the effectiveness of these interventions, particularly related to couple relationship quality. We carried out a validation study of the CFAT among 401 married and cohabiting adults (203 women and 198 men) in rural Chikhwawa District, Malawi. Using psychometric scales, the CFAT addressed six domains of couple relationship quality (intimacy, partner support, sexual satisfaction, gender roles, decision making, and communication and conflict management), and included questions on intimate partner violence. We used exploratory factor analysis to assess scale performance of each domain and produce a shortened Relationship Quality Index (RQI) composed of items from five relationship quality domains. This article reports the performance of the RQI. Internal reliability and validity of the RQI were found to be good. Regression analyses examined the relationship of the RQI to outcomes important to health and development: intra-household cooperation, positive health behaviors, intimate partner violence, and gender-equitable norms. We found many significant correlations between RQI scores and these couple- and family-level development issues. There is a need to further validate the tool with use in other populations as well as to continue to explore whether the observed linkages between couple functionality and development outcomes are causal relationships. PMID- 29190770 TI - Genetic diversity and population structure analysis of spinach by single nucleotide polymorphisms identified through genotyping-by-sequencing. AB - Spinach (Spinacia oleracea L., 2n = 2x = 12) is an economically important vegetable crop worldwide and one of the healthiest vegetables due to its high concentrations of nutrients and minerals. The objective of this research was to conduct genetic diversity and population structure analysis of a collection of world-wide spinach genotypes using single nucleotide polymorphisms (SNPs) markers. Genotyping by sequencing (GBS) was used to discover SNPs in spinach genotypes. Three sets of spinach genotypes were used: 1) 268 USDA GRIN spinach germplasm accessions originally collected from 30 countries; 2) 45 commercial spinach F1 hybrids from three countries; and 3) 30 US Arkansas spinach cultivars/breeding lines. The results from this study indicated that there was genetic diversity among the 343 spinach genotypes tested. Furthermore, the genetic background in improved commercial F1 hybrids and in Arkansas cultivars/lines had a different structured populations from the USDA germplasm. In addition, the genetic diversity and population structures were associated with geographic origin and germplasm from the US Arkansas breeding program had a unique genetic background. These data could provide genetic diversity information and the molecular markers for selecting parents in spinach breeding programs. PMID- 29190772 TI - Fairness in optimizing bus-crew scheduling process. AB - This work proposes a model considering fairness in the problem of crew scheduling for bus drivers (CSP-BD) using a hybrid ant-colony optimization (HACO) algorithm to solve it. The main contributions of this work are the following: (a) a valid approach for cases with a special cost structure and constraints considering the fairness of working time and idle time; (b) an improved algorithm incorporating Gamma heuristic function and selecting rules. The relationships of each cost are examined with ten bus lines collected from the Beijing Public Transport Holdings (Group) Co., Ltd., one of the largest bus transit companies in the world. It shows that unfair cost is indirectly related to common cost, fixed cost and extra cost and also the unfair cost approaches to common and fixed cost when its coefficient is twice of common cost coefficient. Furthermore, the longest time for the tested bus line with 1108 pieces, 74 blocks is less than 30 minutes. The results indicate that the HACO-based algorithm can be a feasible and efficient optimization technique for CSP-BD, especially with large scale problems. PMID- 29190771 TI - Synergistic role of 5-azacytidine and ascorbic acid in directing cardiosphere derived cells to cardiomyocytes in vitro by downregulating Wnt signaling pathway via phosphorylation of beta-catenin. AB - BACKGROUND: Cardiosphere derived cells (CDCs) represent a valuable source in stem cell based therapy for cardiovascular diseases, yet poor differentiation rate hinders the transplantation efficiency. The aim of this study is to check the ability of 5-Azacytidine (Aza) alone and in combination with ascorbic acid (Aza+AA) in delineating CDCs to cardiomyogenesis and the underlying Wnt signaling mechanism in induced differentiation. METHODS: CDCs were treated with Aza and Aza+AA for a period of 14 days to examine the expression of cardiac specific markers and Wnt downstream regulators by immunofluorescence, real time PCR and western blot. RESULTS: Results revealed that Aza+AA induced efficient commitment of CDCs to cardiomyogenic lineage. Immunofluorescence analysis showed significant augment for Nkx 2.5, GATA 4 and alpha-Sarcomeric actinin markers in Aza+AA group than control group (p = 0.0118, p = 0.009 and p = 0.0091, respectively). Relative upregulation of cardiac markers, Nkx 2.5 (p = 0.0156), GATA 4 (p = 0.0087) and down regulation of Wnt markers, beta-catenin (p = 0.0107) and Cyclin D1 (p = 0. 0116) in Aza+AA group was revealed by RNA expression analysis. Moreover, the Aza+AA induced prominent expression of GATA 4, alpha-Sarcomeric actinin and phospho beta-catenin while non phospho beta-catenin and Cyclin D1 expression was significantly suppressed as displayed in protein expression analysis. Generation of spontaneous beating in Aza+AA treated CDCs further reinforced that Aza+AA accelerates the cardiomyogenic potential of CDCs. CONCLUSION: Combined treatment of Aza along with AA implicit in inducing cardiomyogenic potential of CDCs and is associated with down regulating Wnt signaling pathway. Altogether, CDCs represent a valuable tool for the treatment of cardiovascular disorders.

PMID- 29190775 TI - Transcriptome profiling analysis of senescent gingival fibroblasts in response to Fusobacterium nucleatum infection. AB - Periodontal disease is caused by dental plaque biofilms. Fusobacterium nucleatum is an important periodontal pathogen involved in the development of bacterial complexity in dental plaque biofilms. Human gingival fibroblasts (GFs) act as the first line of defense against oral microorganisms and locally orchestrate immune responses by triggering the production of reactive oxygen species and pro inflammatory cytokines (IL-6 and IL-8). The frequency and severity of periodontal diseases is known to increase in elderly subjects. However, despite several studies exploring the effects of aging in periodontal disease, the underlying mechanisms through which aging affects the interaction between F. nucleatum and human GFs remain unclear. To identify genes affected by infection, aging, or both, we performed an RNA-Seq analysis using GFs isolated from a single healthy donor that were passaged for a short period of time (P4) 'young GFs' or for longer period of time (P22) 'old GFs', and infected or not with F. nucleatum. Comparing F. nucleatum-infected and uninfected GF(P4) cells the differentially expressed genes (DEGs) were involved in host defense mechanisms (i.e., immune responses and defense responses), whereas comparing F. nucleatum-infected and uninfected GF(P22) cells the DEGs were involved in cell maintenance (i.e., TGF beta signaling, skeletal development). Most DEGs in F. nucleatum-infected GF(P22) cells were downregulated (85%) and were significantly associated with host defense responses such as inflammatory responses, when compared to the DEGs in F. nucleatum-infected GF(P4) cells. Five genes (GADD45b, KLF10, CSRNP1, ID1, and TM4SF1) were upregulated in response to F. nucleatum infection; however, this effect was only seen in GF(P22) cells. The genes identified here appear to interact with each other in a network associated with free radical scavenging, cell cycle, and cancer; therefore, they could be potential candidates involved in the aged GF's response to F. nucleatum infection. Further studies are needed to confirm these observations. PMID- 29190774 TI - Activation of the cholinergic anti-inflammatory pathway by GTS-21 attenuates cisplatin-induced acute kidney injury in mice. AB - Acute kidney injury (AKI) is the most common side effect of cisplatin, a widely used chemotherapy drug. Although AKI occurs in up to one third of cancer patients receiving cisplatin, effective renal protective strategies are lacking. Cisplatin targets renal proximal tubular epithelial cells leading to inflammation, reactive oxygen species, tubular cell injury, and eventually cell death. The cholinergic anti-inflammatory pathway is a vagus nerve-mediated reflex that suppresses inflammation via alpha7 nicotinic acetylcholine receptors (alpha7nAChRs). Our previous studies demonstrated the renoprotective and anti-inflammatory effects of cholinergic agonists, including GTS-21. Therefore, we examined the effect of GTS 21 on cisplatin-induced AKI. Male C57BL/6 mice received either saline or GTS-21 (4mg/kg, i.p.) twice daily for 4 days before cisplatin and treatment continued through euthanasia; 3 days post-cisplatin mice were euthanized and analyzed for markers of renal injury. GTS-21 significantly reduced cisplatin-induced renal dysfunction and injury (p<0.05). GTS-21 significantly attenuated renal Ptgs2/COX 2 mRNA and IL-6, IL-1beta, and CXCL1 protein expression, as well as neutrophil infiltration after cisplatin. GTS-21 blunted cisplatin-induced renal ERK1/2 activation, as well as renal ATP depletion and apoptosis (p<0.05). GTS-21 suppressed the expression of CTR1, a cisplatin influx transporter and enhanced the expression of cisplatin efflux transporters MRP2, MRP4, and MRP6 (p<0.05). Using breast, colon, and lung cancer cell lines we showed that GTS-21 did not inhibit cisplatin's tumor cell killing activity. GTS-21 protects against cisplatin-AKI by attenuating renal inflammation, ATP depletion and apoptosis, as well as by decreasing renal cisplatin influx and increasing efflux, without impairing cisplatin-mediated tumor cell killing. Our results support further exploring the cholinergic anti-inflammatory pathway for preventing cisplatin induced AKI. PMID- 29190777 TI - Embedding resilience in the design of the electricity supply for industrial clients. AB - This paper proposes an optimization model, using Mixed-Integer Linear Programming (MILP), to support decisions related to making investments in the design of power grids serving industrial clients that experience interruptions to their energy supply due to disruptive events. In this approach, by considering the probabilities of the occurrence of a set of such disruptive events, the model is used to minimize the overall expected cost by determining an optimal strategy involving pre- and post-event actions. The pre-event actions, which are considered during the design phase, evaluate the resilience capacity (absorption, adaptation and restoration) and are tailored to the context of industrial clients dependent on a power grid. Four cases are analysed to explore the results of different probabilities of the occurrence of disruptions. Moreover, two scenarios, in which the probability of occurrence is lowest but the consequences are most serious, are selected to illustrate the model's applicability. The results indicate that investments in pre-event actions, if implemented, can enhance the resilience of power grids serving industrial clients because the impacts of disruptions either are experienced only for a short time period or are completely avoided. PMID- 29190776 TI - Large-scale identification of human cerebrovascular proteins: Inter-tissue and intracerebral vascular protein diversity. AB - The human cerebrovascular system is responsible for regulating demand-dependent perfusion and maintaining the blood-brain barrier (BBB). In addition, defects in the human cerebrovasculature lead to stroke, intracerebral hemorrhage, vascular malformations, and vascular cognitive impairment. The objective of this study was to discover new proteins of the human cerebrovascular system using expression data from the Human Protein Atlas, a large-scale project which allows public access to immunohistochemical analysis of human tissues. We screened 20,158 proteins in the HPA and identified 346 expression patterns correlating to blood vessels in human brain. Independent experiments showed that 51/52 of these distributions could be experimentally replicated across different brain samples. Some proteins (40%) demonstrated endothelial cell (EC)-enriched expression, while others were expressed primarily in vascular smooth muscle cells (VSMC; 18%); 39% of these proteins were expressed in both cell types. Most brain EC markers were tissue oligospecific; that is, they were expressed in endothelia in an average of 4.8 out of 9 organs examined. Although most markers expressed in endothelial cells of the brain were present in all cerebral capillaries, a significant number (21%) were expressed only in a fraction of brain capillaries within each brain sample. Among proteins found in cerebral VSMC, virtually all were also expressed in peripheral VSMC and in non-vascular smooth muscle cells (SMC). Only one was potentially brain specific: VHL (Von Hippel-Lindau tumor suppressor). HRC (histidine rich calcium binding protein) and VHL were restricted to VSMC and not found in non-vascular tissues such as uterus or gut. In conclusion, we define a set of brain vascular proteins that could be relevant to understanding the unique physiology and pathophysiology of the human cerebrovasculature. This set of proteins defines inter-organ molecular differences in the vasculature and confirms the broad heterogeneity of vascular cells within the brain. PMID- 29190779 TI - Manifold absolute pressure estimation using neural network with hybrid training algorithm. AB - In a modern small gasoline engine fuel injection system, the load of the engine is estimated based on the measurement of the manifold absolute pressure (MAP) sensor, which took place in the intake manifold. This paper present a more economical approach on estimating the MAP by using only the measurements of the throttle position and engine speed, resulting in lower implementation cost. The estimation was done via two-stage multilayer feed-forward neural network by combining Levenberg-Marquardt (LM) algorithm, Bayesian Regularization (BR) algorithm and Particle Swarm Optimization (PSO) algorithm. Based on the results found in 20 runs, the second variant of the hybrid algorithm yields a better network performance than the first variant of hybrid algorithm, LM, LM with BR and PSO by estimating the MAP closely to the simulated MAP values. By using a valid experimental training data, the estimator network that trained with the second variant of the hybrid algorithm showed the best performance among other algorithms when used in an actual retrofit fuel injection system (RFIS). The performance of the estimator was also validated in steady-state and transient condition by showing a closer MAP estimation to the actual value. PMID- 29190778 TI - MiR-6835 promoted LPS-induced inflammation of HUVECs associated with the interaction between TLR-4 and AdipoR1 in lipid rafts. AB - BACKGROUND: High mortality rate of critically-ill patients could be induced by sepsis and septic shock, which is the extremely life threatening. The purpose of this work is to identify and evaluate the potential regulatory mechanism of LPS induced inflammation associated with miR-6835 and lipid rafts in HUVECs. METHODS: The 3' UTR luciferase activity of AdipoR1 was detected, which was predicted the potential target gene of miR-6835. Moreover, the treated HUVECs with or without inhibitors or mimics of miR-6835 were used. Furthermore, the bio-functions of HUVECs were explored. The protein expression levels of SIRT-1, AMPK, and AdipoR1 were assessed, which were involved in the AdipoR1 signaling pathway. Then, the interaction between TLR-4 and AdipoR1 in lipid rafts and its mediation role on LPS-induced inflammation was investigated in HUVECs. RESULTS: MiR-6835 targeted directly on AdipoR1, and suppressed its expression in mRNA (mimics of miR-6835: 0.731+/-0.016 vs control: 1.527+/-0.015, P<0.001) and proteins levels, then regulated protein expression of SIRT-1 and AMPK, which were the downstream target genes of AdipoR1 signaling pathway. MiR-6835 enhanced LPS-induced inflammation process in HUVECs (TNF-alpha: LPS+mimics of miR-6835: 1638.51+/-78.43 vs LPS: 918.73+/-39.73, P<0.001; IL-6: LPS+mimics of miR-6835: 1249.35+/-69.51 vs LPS: 687.52+/-43.64, P<0.001), which was associated with the interaction between TLR-4 and AdipoR1 in lipid rafts. CONCLUSIONS: MiR-6835 is the key regulator of LPS induced inflammation process in HUVECs. The interaction between TLR-4 and AdipoR1 mediated by lipid rafts at membrane of HUVECs with inflammation process induced by miR-6835. Our results demonstrated a hopeful strategy for treatment on sepsis by aiming at lipid rafts and miR-6835. PMID- 29190780 TI - Characterization of thermostable alkaline proteases from Bacillus infantis SKS1 isolated from garden soil. AB - Proteases are one of the largest groups of hydrolytic enzymes constituting about 60% of total worldwide sales of industrial enzymes due to their wide applications in detergent, leather, textile, food and pharmaceutical industry. Microbial proteases have been preferred over animal and plant proteases because of their fundamental features and ease in production. Bacillus infantis SKS1, an alkaline protease producing bacteria has been isolated from garden soil of north India and identified using morphological, biochemical and molecular methods. 16S rDNA sequence amplified using universal primers has 99% sequence identity with corresponding gene sequence of Bacillus infantis strain FM 34 and Bacillus sp. Beige. The bacterial culture and its 16S rDNA gene sequence have been deposited to Microbial Culture Collection (Pune, India) with accession number MCC 3035 and GenBank with accession number KR092197 respectively. The partially purified extract of Bacillus infantis SKS1 was thermostable and active in presence of Mg2+, acetyl acetone and laundry detergents implicating its application in industry. Production of these enzymes using this strain was maximized by optimization of various parameters including temperature, pH, media components and other growth conditions. Our results show that fructose and dextrose serve as the best carbon sources for production of these enzymes, highlighting the use of this strain for enzyme production utilizing relatively inexpensive substrates like beet molasses and corn steep liquor. Additionally, this strain showed maximum production of enzymes at 40 degrees C similar to bacterial species used for commercial production of alkaline proteases. Characterization of alkaline proteases from this strain of Bacillus infantis and optimization of parameters for its production would help in understanding its industrial application and large-scale production. PMID- 29190782 TI - Addressing the cost of infractions in the online literature and databases. AB - Myocardial infarction sometimes appears misspelt as myocardial infraction in the cardiovascular research literature. With accurate citation of literature contributions important to advancing the field and its contributors, in this study we aimed to document the frequency and explore the causes and impact of this error specific to the cardiology literature. Literature databases (PubMed, Scopus, Web of Science, WIPO, Google Scholar, Google) were searched to identify the rate of myocardial infraction errors and found an error rate between 0.2% and 1.6%, with substantial differences between search tools used. A Scopus search was used to show changes in errors over time, differences between journals and by specific authors. Myocardial infraction occurred at increasing annual rates over time and at higher rates than other errors. Increasing error rates were associated with increased volume of searchable material rather than quality of the literature. Transcription from article to database is a common source of error and some databases have higher rates of these errors. Simple measures to avoid and to correct these errors in the literature and the databases are also discussed. PMID- 29190781 TI - Roles of CD34+ cells and ALK5 signaling in the reconstruction of seminiferous tubule-like structures in 3-D re-aggregate culture of dissociated cells from neonatal mouse testes. AB - Tissue reconstruction in vitro can provide, if successful, a refined and simple system to analyze the underlying mechanisms that drive the morphogenesis and maintain the ordered structure. We have recently succeeded in reconstruction of seminiferous cord-like and tubule-like structures using 3-D re-aggregate culture of dissociated testicular cells. In testis formation, endothelial cells that migrated from mesonephroi to embryonic gonads have been shown to be critical for development of testis cords, but how endothelial cells contribute to testis cord formation remains unknown. To decipher the roles of endothelial and peritubular cells in the reconstruction of cord-like and tubule-like structures, we investigated the behavior of CD34+ endothelial and p75+ cells, and peritubular myoid cells (PTMCs) in 3-D re-aggregate cultures of testicular cells. The results showed that these 3 types of cells had the capacity of re-aggregation on their own and with each other, and of segregation into 3 layers in a re-aggregate, which were very similar to interstitial and peritubular tissues in vivo. Observation of behaviors of fluorescent Sertoli cells and other non-fluorescent types of cells using testes from Sox9-EGFP transgenic mice showed dynamic cell movement and segregation in re-aggregate cultures. Cultures of testicular cells deprived of interstitial and peritubular cells resulted in dysmorphic structures, but re-addition of them restored tubule-like structures. Purified CD34+ cells in culture differentiated into p75+ cells and PTMCs. These results indicate that CD34+ cells differentiate into p75+ cells, which then differentiate into PTMCs. TGFbeta signaling inhibitors, SB431542 and ALK5i, disturbed the reconstruction of cord-like and tubule-like structures, and the latter compromised re-construction of interstitial-like and peritubular-like structures, as well as the proliferation of CD34+, p75+, PTMCs, and Sertoli cells, and their movement and differentiation. These results indicate that CD34+ cells and signaling through ALK5 play pivotal roles in the morphogenesis of interstitial-like, peritubular like and cord-like structures. PMID- 29190783 TI - Satellite imagery-based monitoring of archaeological site damage in the Syrian civil war. AB - Since the start of the Syrian civil war in 2011, the rich archaeological heritage of Syria and northern Iraq has faced severe threats, including looting, combat related damage, and intentional demolition of monuments. However, the inaccessibility of the conflict zone to archaeologists or cultural heritage specialists has made it difficult to produce accurate damage assessments, impeding efforts to develop mitigation strategies and policies. This paper presents results of a project, undertaken in collaboration with the American Schools of Oriental Research (ASOR) and the US Department of State, to monitor damage to archaeological sites in Syria, northern Iraq, and southern Turkey using recent, high-resolution satellite imagery. Leveraging a large database of archaeological and heritage sites throughout the region, as well as access to continually updated satellite imagery from DigitalGlobe, this project has developed a flexible and efficient methodology to log observations of damage in a manner that facilitates spatial and temporal queries. With nearly 5000 sites carefully evaluated, analysis reveals unexpected patterns in the timing, severity, and location of damage, helping us to better understand the evolving cultural heritage crisis in Syria and Iraq. Results also offer a model for future remote sensing-based archaeological and heritage monitoring efforts in the Middle East and beyond.

AB - OBJECTIVE: In France, indications for pre-exposure prophylaxis (PrEP) for HIV prevention are based on individual-level risk factors for HIV infection. However, the risk of HIV infection may also depend on characteristics of sexual partnerships. Here we study how place-based selection of partners change transmission and the overall efficiency of PrEP. METHODS: We used the PREVAGAY survey of sexual behavior and HIV serostatus in men who have sex with men (MSM) in a Parisian district to look for associations between sexual network characteristics and HIV infection. We then simulated HIV transmission in a high risk MSM population. We used information about venues visited to meet casual sexual partners (clubs, backrooms or saunas) to define sexual networks. We then simulated HIV transmission in these networks and assessed the impact of PrEP in this population. RESULTS: In the PREVAGAY study, we found that HIV serostatus changed with the type of venues visited, in addition to other individual risk factors. In simulations, we found similar differences in HIV incidence when the choice of venues visited was not random. The use of PrEP allowed reducing incidence, irrespective of the venues visited by PrEP users. However, with the same amount of PrEP, the number of infections adverted could almost double depending on network structure and venues visited by PrEP users. CONCLUSION: This study shows that characteristics of the sexual network structure can strongly impact the effectiveness of PrEP interventions. These should be considered further to refine individual risk assessment and maximize the effect of individual-based prevention policies.

AB - Alveolar bone remodelling is vital for the success of dental implants and orthodontic treatments. However, the underlying biomechanical mechanisms, in particular the function of the periodontal ligament (PDL) in bone loading and remodelling, are not well understood. The PDL is a soft fibrous connective tissue that joins the tooth root to the alveolar bone and plays a critical role in the transmission of loads from the tooth to the surrounding bone. However, due to its complex structure, small size and location within the tooth socket it is difficult to study in vivo. Finite element analysis (FEA) is an ideal tool with which to investigate the role of the PDL, however inclusion of the PDL in FE models is complex and time consuming, therefore consideration must be given to how it is included. The aim of this study was to investigate the effects of including the PDL and its fibrous structure in mandibular finite element models. A high-resolution model of a human molar region was created from micro-computed tomography scans. This is the first time that the fibrous structure of the PDL has been included in a model with realistic tooth and bone geometry. The results show that omission of the PDL creates a more rigid model, reducing the strains observed in the mandibular corpus which are of interest when considering mandibular functional morphology. How the PDL is modelled also affects the strains. The inclusion of PDL fibres alters the strains in the mandibular bone, increasing the strains in the tooth socket compared to PDL modelled without fibres. As strains in the alveolar bone are thought to play a key role in bone remodelling during orthodontic tooth movement, future FE analyses aimed at improving our understanding and management of orthodontic treatment should include the fibrous structure of the PDL. PMID- 29190786 TI - Unsupervised morphological segmentation of tissue compartments in histopathological images. AB - Algorithmic segmentation of histologically relevant regions of tissues in digitized histopathological images is a critical step towards computer-assisted diagnosis and analysis. For example, automatic identification of epithelial and stromal tissues in images is important for spatial localisation and guidance in the analysis and characterisation of tumour micro-environment. Current segmentation approaches are based on supervised methods, which require extensive training data from high quality, manually annotated images. This is often difficult and costly to obtain. This paper presents an alternative data independent framework based on unsupervised segmentation of oropharyngeal cancer tissue micro-arrays (TMAs). An automated segmentation algorithm based on mathematical morphology is first applied to light microscopy images stained with haematoxylin and eosin. This partitions the image into multiple binary 'virtual cells', each enclosing a potential 'nucleus' (dark basins in the haematoxylin absorbance image). Colour and morphology measurements obtained from these virtual cells as well as their enclosed nuclei are input into an advanced unsupervised learning model for the identification of epithelium and stromal tissues. Here we exploit two Consensus Clustering (CC) algorithms for the unsupervised recognition of tissue compartments, that consider the consensual opinion of a group of individual clustering algorithms. Unlike most unsupervised segmentation analyses, which depend on a single clustering method, the CC learning models allow for more robust and stable detection of tissue regions. The proposed framework performance has been evaluated on fifty-five hand-annotated tissue images of oropharyngeal tissues. Qualitative and quantitative results of the proposed segmentation algorithm compare favourably with eight popular tissue segmentation strategies. Furthermore, the unsupervised results obtained here outperform those obtained with individual clustering algorithms.

AB - Preoperative planning for total hip arthroplasty includes templating on anteroposterior radiographs. It is necessary to consider radiographic magnification in order to scale templates accurately. Studies dealing with hip templating report different values of radiographic magnification. It is not clear if the observed difference in magnification between the studies is caused by variability in studied groups, methodology or instrumentation. We hypothesize that there is a difference in magnification between clinical workplaces. Within this study, radiographic magnification was estimated on 337 radiographs of patients after total hip surgery from five orthopaedic departments in the Czech Republic. Magnification was determined for each patient as a ratio between diameter of implanted femoral head measured on radiogram and its true size. One way ANOVA revealed significant differences in magnification between workplaces (F(4,332) = 132, p<=0.001). These results suggest that radiographic magnification depends on the workplace where it is taken or more precisely on radiographic device. It indicates potential limits in generalizability of results of studies dealing with preoperative planning accuracy to other institutions. PMID- 29190788 TI - Non-invasive assessment of pulsatile intracranial pressure with phase-contrast magnetic resonance imaging. AB - Invasive monitoring of pulsatile intracranial pressure can accurately predict shunt response in patients with idiopathic normal pressure hydrocephalus, but may potentially cause complications such as bleeding and infection. We tested how a proposed surrogate parameter for pulsatile intracranial pressure, the phase contrast magnetic resonance imaging derived pulse pressure gradient, compared with its invasive counterpart. In 22 patients with suspected idiopathic normal pressure hydrocephalus, preceding invasive intracranial pressure monitoring, and any surgical shunt procedure, we calculated the pulse pressure gradient from phase-contrast magnetic resonance imaging derived cerebrospinal fluid flow velocities obtained at the upper cervical spinal canal using a simplified Navier Stokes equation. Repeated measurements of the pulse pressure gradient were also undertaken in four healthy controls. Of 17 shunted patients, 16 responded, indicating high proportion of "true" normal pressure hydrocephalus in the patient cohort. However, there was no correlation between the magnetic resonance imaging derived pulse pressure gradient and pulsatile intracranial pressure (R = -.18, P = .43). Pulse pressure gradients were also similar in patients and healthy controls (P = .26), and did not differ between individuals with pulsatile intracranial pressure above or below established thresholds for shunt treatment (P = .97). Assessment of pulse pressure gradient at level C2 was therefore not found feasible to replace invasive monitoring of pulsatile intracranial pressure in selection of patients with idiopathic normal pressure hydrocephalus for surgical shunting. Unlike invasive, overnight monitoring, the pulse pressure gradient from magnetic resonance imaging comprises short-term pressure fluctuations only. Moreover, complexity of cervical cerebrospinal fluid flow and pulsatility at the upper cervical spinal canal may render the pulse pressure gradient a poor surrogate marker for intracranial pressure pulsations. PMID- 29190789 TI - Consumption of minimally processed food is inversely associated with excess weight in adolescents living in an underdeveloped city. AB - BACKGROUND: The consumption of ultra-processed foods may be associated with the development of chronic diseases, both in adults and in children/adolescents. This consumption is growing worldwide, especially in low and middle-income countries. Nevertheless, its magnitude in small, poor cities from the countryside is not well characterized, especially in adolescents. This study aimed to assess the consumption of minimally processed, processed and ultra-processed foods by adolescents from a poor Brazilian city and to determine if it was associated with excess weight, high waist circumference and high blood pressure. METHODS: Cross sectional study, conducted at a public federal school that offers technical education together with high school, located in the city of Murici. Adolescents of both sexes and aged between 14-19 years old were included. Anthropometric characteristics (weight, height, waist circumference), blood pressure, and dietary intake data were assessed. Associations were calculated using Poisson regression models, adjusted by sex and age. RESULTS: At total, 249 adolescents were included, being 55.8% girls, with a mean age of 16 years-old. The consumption of minimally processed foods was inversely associated with excess weight (Adjusted Prevalence Ratio: 0.61, 95% Confidence Interval: [0.39-0.96], P = 0.03). Although the consumption of ultra-processed foods was not associated with excess weight, high blood pressure and high waist circumference, 46.2% of the sample reported eating these products more than weekly. CONCLUSION: Consumption of minimally processed food is inversely associated with excess weight in adolescents. Investments in nutritional education aiming the prevention of chronic diseases associated with the consumption of these foods are necessary. PMID- 29190790 TI - InDel marker based genetic differentiation and genetic diversity in traditional rice (Oryza sativa L.) landraces of Chhattisgarh, India. AB - Rice has been cultivating and utilizing by humans for thousands of years under diverse environmental conditions. Therefore, tremendous genetic differentiation and diversity has occurred at various agro-ecosystems. The significant indica japonica differentiation in rice provides great opportunities for its genetic improvement. In the present investigation, a total of 42 polymorphic InDel markers were used for differentiating 188 rice landraces and two local varieties of Chhattisgarh, India into indica and japonica related genotypes based on 'InDel molecular index'. Frequency of japonica alleles varied from 0.11 to 0.89 among landraces. Results revealed that 104 rice landraces have indica type genetic architecture along with three tested indica cultivars Swarna, Mahamaya and Rajeshwari. Another 60 landraces were placed under 'close to indica' type. It was found that three rice landraces i.e. Kalajeera, Kapri, Tulsimala were 'close to japonica' type and 21 landraces were 'intermediate' type. The result from the calculation of 'InDel molecular index' was further verified with STRUCTURE, AMOVA, PCA and cluster analysis. Population structure analysis revealed two genetically distinct populations within the 190 rice landraces/genotypes. Based on AMOVA, 'intermediate' type, 'close to japonica' type and Dongjinbyeo (a japonica cultivar from Republic of Korea) displayed significant genetic differentiation (phiPT = 0.642, P = 0.000) from 'indica' and 'close to indica' groups. The PCA scatter plot and dendrogram demonstrated a clear pattern of two major group differentiations. 'Close to japonica' type and 'intermediate' type landraces/genotypes were grouped with Dongjinbyeo and formed a separate cluster at 30% Jaccard's similarity level from rest of the landraces/genotypes which were 'close to indica' or 'indica' type. Such a significant genetic differentiation among the locally adapted landraces could be exploited for the development of rice varieties introgressing higher yield potential and better plant types of japonica type as per the need of consumers and rice traders. PMID- 29190791 TI - Can self-testing increase HIV testing among men who have sex with men: A systematic review and meta-analysis. AB - BACKGROUND: Globally, four out of ten individuals living with HIV have not been tested for HIV. Testing is especially important for men who have sex with men (MSM), among whom an increasing HIV epidemic has been identified in many regions of the world. As a supplement to site-based HIV testing services, HIV self testing (HIVST) provides a promising approach to promote HIV testing. However, evidence is scattered and not well-summarized on the effect of HIVST to improve HIV testing behaviors, especially for MSM. METHODS: Seven databases (PubMed, Web of Science, Cochrane Library, PsycINFO, CINAHL Plus, WanFang, and China National Knowledge Internet) and conference abstracts from six HIV/sexually transmitted infections conferences were searched from January 2000-April 2017. RESULTS: Of 1,694 records retrieved, 23 studies were identified, 9 conducted in resource limited countries and 14 in high-income countries. The pooled results showed that HIVST increased HIV test frequency for MSM by one additional test in a 6-month period (mean difference = 0.88 [95% CI 0.52-1.24]). The pooled proportion of first-time testers among those who took HIVST was 18.7% (95% CI: 9.9-32.4) globally, with a rate 3.32 times higher in resource-limited country settings (32.9% [95% CI: 21.3-47.6]) than in high-income countries (9.9% [95% CI: 7.4 13.8]). The pooled proportions included non-recent testers, 32.9% (95% CI: 28.1 38.3); ever or currently married MSM, 16.7% (95% CI: 14.5-19.4); and HIV positive men, 3.8% (95% CI: 2.0-5.7) globally; 6.5% [95% CI: 0.38-12.3] in resource limited country settings; and 2.9% [95% CI: 2.0-5.0] in high-income countries). The rates reported for linkage to care ranged from 31.3% to 100%. CONCLUSIONS: HIVST could increase HIV testing frequency and potentially have capacity equivalent to that of site-based HIV testing services to reach first-time, delayed, married, and HIV-infected testers among MSM and link them to medical care. However, more rigorous study designs are needed to explore the specific self-testing approach (oral-fluid based or finger-prick based) on improving HIV testing for MSM in different social and economic settings. PMID- 29190792 TI - Molecular genetic diversity and population structure of Ethiopian white lupin landraces: Implications for breeding and conservation. AB - White lupin is one of the four economically important species of the Lupinus genus and is an important grain legume in the Ethiopian farming system. However, there has been limited research effort to characterize the Ethiopian white lupin landraces. Fifteen polymorphic simple sequence repeat (SSR) markers were used to assess the genetic diversity and population structure of 212 Ethiopian white lupin (Lupinus albus) landraces and two genotypes from different species (Lupinus angustifolius and Lupinus mutabilis) were used as out-group. The SSR markers revealed 108 different alleles, 98 of them from 212 landraces and 10 from out group genotypes, with an average of 6.5 alleles per locus. The average gene diversity was 0.31. Twenty eight landraces harbored one or more private alleles from the total of 28 private alleles identified in the 212 white lupin accessions. Seventy-seven rare alleles with a frequency of less than 5% were identified and accounted for 78.6% of the total alleles detected. Analysis of molecular variance (AMOVA) showed that 92% of allelic diversity was attributed to individual accessions within populations while only 8% was distributed among populations. At 70% similarity level, the UPGMA dendrogram resulted in the formation of 13 clusters comprised of 2 to 136 landraces, with the out-group genotypes and five landraces remaining distinct and ungrouped. Population differentiation and genetic distance were relatively high between Gondar and Ethiopian white lupin populations collected by Australians. A model-based population structure analysis divided the white lupin landraces into two populations. All Ethiopian white lupin landrace populations, except most of the landraces collected by Australians (77%) and about 44% from Awi, were grouped together with significant admixtures. The study also suggested that 34 accessions, as core collections, were sufficient to retain 100% of SSR diversity. These accessions (core G-34) represent 16% of the whole 212 Ethiopian white lupin accessions and populations from West Gojam, Awi and Australian collections contributed more accessions to the core collection. PMID- 29190793 TI - Transcriptome analysis of WRKY gene family in Oryza officinalis Wall ex Watt and WRKY genes involved in responses to Xanthomonas oryzae pv. oryzae stress. AB - Oryza officinalis Wall ex Watt, a very important and special wild rice species, shows abundant genetic diversity and disease resistance features, especially high resistance to bacterial blight. The molecular mechanisms of bacterial blight resistance in O. officinalis have not yet been elucidated. The WRKY transcription factor family is one of the largest gene families involved in plant growth, development and stress response. However, little is known about the numbers, structure, molecular phylogenetics, and expression of the WRKY genes under Xanthomonas oryzae pv. oryzae (Xoo) stress in O. officinalis due to lacking of O. officinalis genome. Therefore, based on the RNA-sequencing data of O. officinalis, we performed a comprehensive study of WRKY genes in O. officinalis and identified 89 OoWRKY genes. Then 89 OoWRKY genes were classified into three groups based on the WRKY domains and zinc finger motifs. Phylogenetic analysis strongly supported that the evolution of OoWRKY genes were consistent with previous studies of WRKYs, and subgroup IIc OoWRKY genes were the original ancestors of some group II and group III OoWRKYs. Among the 89 OoWRKY genes, eight OoWRKYs displayed significantly different expression (>2-fold, p<0.01) in the O. officinalis transcriptome under Xoo strains PXO99 and C5 stress 48 h, suggesting these genes might play important role in PXO99 and C5 stress responses in O. officinalis. QRT-PCR analysis and confirmation of eight OoWRKYs expression patterns revealed that they responded strongly to PXO99 and C5 stress 24 h, 48 h, and 72 h, and the trends of these genes displaying marked changes were consistent with the 48 h RNA-sequencing data, demonstrated these genes played important roles in response to biotic stress and might even involved in the bacterial blight resistance. Tissue expression profiles of eight OoWRKY genes revealed that they were highly expressed in root, stem, leaf, and flower, especially in leaf (except OoWRKY71), suggesting these genes might be also important for plant growth and organ development. In this study, we analyzed the WRKY family of transcription factors in O.officinalis. Insight was gained into the classification, evolution, and function of the OoWRKY genes, revealing the putative roles of eight significantly different expression OoWRKYs in Xoo strains PXO99 and C5 stress responses in O.officinalis. This study provided a better understanding of the evolution and functions of O. officinalis WRKY genes, and suggested that manipulating eight significantly different expression OoWRKYs would enhance resistance to bacterial blight. PMID- 29190794 TI - 3D collagen fibrillar microstructure guides pancreatic cancer cell phenotype and serves as a critical design parameter for phenotypic models of EMT. AB - Pancreatic cancer, one of the deadliest cancers, is characterized by high rates of metastasis and intense desmoplasia, both of which are associated with changes in fibrillar type I collagen composition and microstructure. Epithelial to mesenchymal transition (EMT), a critical step of metastasis, also involves a change in extracellular matrix (ECM) context as cells detach from basement membrane (BM) and engage interstitial matrix (IM). The objective of this work was to develop and apply an in-vitro three-dimensional (3D) tumor-ECM model to define how ECM composition and biophysical properties modulate pancreatic cancer EMT. Three established pancreatic ductal adenocarcinoma (PDAC) lines were embedded within 3D matrices prepared with type I collagen Oligomer (IM) at various fibril densities to control matrix stiffness or Oligomer and Matrigel combined at various ratios while maintaining constant matrix stiffness. Evaluation of cell morphology and protein expression at both the cellular- and population-levels revealed a spectrum of matrix-driven EMT phenotypes that were dependent on ECM composition and architecture as well as initial PDAC phenotype. In general, exposure to fibrillar IM was sufficient to drive EMT, with cells displaying spindle-shaped morphology and mesenchymal markers, and non-fibrillar BM promoted more epithelial behavior. When cultured within low density Oligomer, only a subpopulation of epithelial BxPC-3 cells displayed EMT while mesenchymal MiaPaCa 2 cells displayed more uniform spindle-shaped morphologies and mesenchymal marker expression. Interestingly, as IM fibril density increased, associated changes in spatial constraints and matrix stiffness resulted in all PDAC lines growing as tight clusters; however mesenchymal marker expression was maintained. Collectively, the comparison of these results to other in-vitro tumor models highlights the role of IM fibril microstructure in guiding EMT heterogeneity and showcases the potential of standardized 3D matrices such as Oligomer to serve as robust platforms for mechanistic study of metastasis and creation of predictive drug screening models. PMID- 29190796 TI - Risk factors for the development of chronic pulmonary aspergillosis in patients with nontuberculous mycobacterial lung disease. AB - Nontuberculous mycobacterial lung disease (NTM-LD) is increasingly recognized as an important predisposing condition for the development of chronic pulmonary aspergillosis (CPA), but there are limited data on the risk factors for CPA development in NTM-LD patients. We reviewed the medical records of 566 patients who, at the time of diagnosis of NTM-LD, did not have CPA and who received >=12 months of treatment for NTM-LD between January 2010 and June 2015. Of these patients, 41 (7.2%) developed CPA (NTM-CPA group), whereas the remaining 525 patients did not develop CPA (NTM group). The median time to the development of CPA was 18.0 months from treatment initiation for NTM-LD. The NTM-CPA group was older and had significantly higher proportions of males, current smokers, and patients with a low body mass index (<18.5 kg/m2), when compared to the NTM group. Moreover, the NTM-CPA group was more likely to have a history of tuberculosis and chronic obstructive lung disease and to have used inhaled or systemic steroids. In the NTM-CPA group, more than 40% of patients had Mycobacterium abscessus complex (MABC) as the cause of NTM-LD, and the fibrocavitary form of NTM-LD was the most common; both associations were higher than in the NTM group. Overall, 17 (3%) patients died, and the NTM-CPA group had a higher mortality rate than did the NTM group (19.5% vs. 1.7%, respectively; P<0.001). In a multivariable analysis, old age, male gender, low body mass index, chronic obstructive lung disease, systemic steroids, MABC as the etiologic organism, and the fibrocavitary form of NTM-LD remained significant predictors of development of CPA. In conclusion, CPA occurred in 7.2% of patients after initiation of treatment for NTM-LD, and some risk factors were associated with CPA development. Given the worse prognosis, early diagnosis and treatment of CPA are important in patients with NTM-LD. PMID- 29190795 TI - Expression of phosphatase of regenerating liver (PRL)-3, is independently associated with biochemical failure, clinical failure and death in prostate cancer. AB - BACKGROUND: Prostate cancer (PC) stratification needs new prognostic tools to reduce overtreatment. Phosphatase of regenerating liver (PRL-3) is a phosphatase found at high levels in several cancer types, where its expression is associated with survival. A recent PC cell line study has shown it to be involved in PC growth and migration. METHODS: We used a monoclonal antibody to evaluate the expression of PRL-3 in PC tissue of patients in an unselected cohort of 535 prostatectomy patients. We analyzed associations between PRL-3 expression and biochemical failure-free survival (BFFS), clinical failure-free survival (CFFS) and PC death-free survival (PCDFS). RESULTS: Cytoplasmic PRL-3 staining in tumor cells was significantly correlated to expression of molecules in the VEGFR-axis, but not to the clinicopathological variables. High PRL-3 was not significantly associated with survival in the univariate analysis for BFFS (p = 0.131), but significantly associated with CFFS (p = 0.044) and PCDFS (p = 0.041). In multivariate analysis for the various end points, PRL-3 came out as an independent and significant indicator of poor survival for BFFS (HR = 1.53, CI95% 1.10-2.13, p = 0.012), CFFS (HR = 2.41, CI95% 1.17-4.98, p = 0.017) and PCDFS (HR = 3.99, CI95% 1.21-13.1, p = 0.023). CONCLUSIONS: PRL-3 is independently associated with all PC endpoints in this study. Since high PRL-3 expression also correlates with poor prognosis in other cancers and functional studies in PC support these findings, PRL-3 emerges as a potential treatment target in PC. PMID- 29190797 TI - Topographic characteristics after Descemet's membrane endothelial keratoplasty and Descemet's stripping automated endothelial keratoplasty. AB - PURPOSE: To investigate the topographic characteristics of the posterior corneal surface after Descemet's endothelial membrane keratoplasty (DMEK) and Descemet's stripping automated endothelial keratoplasty (DSAEK) and their effects on postoperative visual acuity. METHODS: Nineteen eyes of 19 patients after DMEK, 23 eyes of 23 patients after DSAEK, and 18 eyes of 18 control subjects were retrospectively analyzed. Best spectacle-corrected visual acuity (BSCVA), aberration factors (higher-order aberrations [HOAs], spherical aberrations [SAs], and coma aberrations [Comas] at 6.0 mm) were evaluated preoperatively and at 1, 3, and 6 months postoperatively. The posterior refractive pattern of the topography map was classified into 5 grades (0-5) (posterior color grade) using anterior segment optical coherence tomography. Correlations between BSCVA and some factors (abbreviation factors, posterior color grade) were analyzed. RESULTS: BSCVA was significantly better after DMEK than after DSAEK (P < 0.001). Posterior HOAs, SAs, and Comas after each type of endothelial keratoplasty were significantly greater compared to control (P < 0.01). Posterior HOAs, total/anterior/posterior SAs, and posterior color grade were significantly lower in the DMEK group than in the DSAEK group at 3 months (P < 0.024 [posterior HOAs], P = 0.047 [total SA], P < 0.001 [anterior SAs], P = 0.021 [posterior SAs], and P < 0.001 [posterior color grade]) and 6 months postoperatively (P = 0.034 [posterior HOAs], P < 0.001 [total SAs], P < 0.001 [anterior SAs], P = 0.013 [posterior SAs], and P = 0.004 [posterior color grade]). BSCVA was significantly correlated with HOAs, SAs, and posterior color grade (P < 0.001 for all except anterior HOAs [P = 0.004]). CONCLUSIONS: High posterior color grades were associated with larger aberration factors and had a negative effect on visual function after endothelial keratoplasty. Rapid improvement of visual function after DMEK may be attributed to less change at the posterior surface. PMID- 29190798 TI - Human pleural fluid is a potent growth medium for Streptococcus pneumoniae. AB - Empyema is defined by the presence of bacteria and/or pus in pleural effusions. However, the biology of bacteria within human pleural fluid has not been studied. Streptococcus pneumoniae is the most common cause of pediatric and frequent cause of adult empyema. We investigated whether S. pneumoniae can proliferate within human pleural fluid and if growth is affected by the cellular content of the fluid and/or characteristics of pneumococcal surface proteins. Invasive S. pneumoniae isolates (n = 24) and reference strain recovered from human blood or empyema were inoculated (1.5*106CFU/mL) into sterile human malignant pleural fluid samples (n = 11). All S. pneumoniae (n = 25) strains proliferated rapidly, increasing by a median of 3009 (IQR 1063-9846) from baseline at 24hrs in all pleural effusions tested. Proliferation was greater than in commercial pneumococcal culture media and concentrations were maintained for 48hrs without autolysis. A similar magnitude of proliferation was observed in pleural fluid before and after removal of its cellular content, p = 0.728. S. pneumoniae (D39 strain) wild-type, and derivatives (n = 12), each with mutation(s) in a different gene required for full virulence were inoculated into human pleural fluid (n = 8). S. pneumoniae with pneumococcal surface antigen A (DeltapsaA) mutation failed to grow (2207-fold lower than wild-type), p<0.001, however growth was restored with manganese supplementation. Growth of other common respiratory pathogens (n = 14) across pleural fluid samples (n = 7) was variable and inconsistent, with some strains failing to grow. We establish for the first time that pleural fluid is a potent growth medium for S. pneumoniae and proliferation is dependent on the PsaA surface protein and manganese. PMID- 29190799 TI - Detecting event-related changes in organizational networks using optimized neural network models. AB - Organizational external behavior changes are caused by the internal structure and interactions. External behaviors are also known as the behavioral events of an organization. Detecting event-related changes in organizational networks could efficiently be used to monitor the dynamics of organizational behaviors. Although many different methods have been used to detect changes in organizational networks, these methods usually ignore the correlation between the internal structure and external events. Event-related change detection considers the correlation and could be used for event recognition based on social network modeling and supervised classification. Detecting event-related changes could be effectively useful in providing early warnings and faster responses to both positive and negative organizational activities. In this study, event-related change in an organizational network was defined, and artificial neural network models were used to quantitatively determine whether and when a change occurred. To achieve a higher accuracy, Back Propagation Neural Networks (BPNNs) were optimized using Genetic Algorithms (GAs) and Particle Swarm Optimization (PSO). We showed the feasibility of the proposed method by comparing its performance with that of other methods using two cases. The results suggested that the proposed method could identify organizational events based on a correlation between the organizational networks and events. The results also suggested that the proposed method not only has a higher precision but also has a better robustness than the previously used techniques. PMID- 29190800 TI - ERRalpha protein is stabilized by LSD1 in a demethylation-independent manner. AB - The LSD1 histone demethylase is highly expressed in breast tumors where it constitutes a factor of poor prognosis and promotes traits of cancer aggressiveness such as cell invasiveness. Recent work has shown that the Estrogen Related Receptor alpha (ERRalpha) induces LSD1 to demethylate the Lys 9 of histone H3. This results in the transcriptional activation of a number of common target genes, several of which being involved in cellular invasion. High expression of ERRalpha protein is also a factor of poor prognosis in breast tumors. Here we show that, independently of its demethylase activities, LSD1 protects ERRalpha from ubiquitination, resulting in overexpression of the latter protein. Our data also suggests that the elevation of LSD1 mRNA and protein in breast cancer (as compared to normal tissue) may be a key event to increase ERRalpha protein, independently of its corresponding mRNA. PMID- 29190801 TI - Comparison between manual and mechanical chest compressions during resuscitation in a pediatric animal model of asphyxial cardiac arrest. AB - AIMS: Chest compressions (CC) during cardiopulmonary resuscitation are not sufficiently effective in many circumstances. Mechanical CC could be more effective than manual CC, but there are no studies comparing both techniques in children. The objective of this study was to compare the effectiveness of manual and mechanical chest compressions with Thumper device in a pediatric cardiac arrest animal model. MATERIAL AND METHODS: An experimental model of asphyxial cardiac arrest (CA) in 50 piglets (mean weight 9.6 kg) was used. Animals were randomized to receive either manual CC or mechanical CC using a pediatric piston chest compressions device (Life-Stat(r), Michigan Instruments). Mean arterial pressure (MAP), arterial blood gases and end-tidal CO2 (etCO2) values were measured at 3, 9, 18 and 24 minutes after the beginning of resuscitation. RESULTS: There were no significant differences in MAP, DAP, arterial blood gases and etCO2 between chest compression techniques during CPR. Survival rate was higher in the manual CC (15 of 30 = 50%) than in the mechanical CC group (3 of 20 = 15%) p = 0.016. In the mechanical CC group there was a non significant higher incidence of haemorrhage through the endotracheal tube (45% vs 20%, p = 0.114). CONCLUSIONS: In a pediatric animal model of cardiac arrest, mechanical piston chest compressions produced lower survival rates than manual chest compressions, without any differences in hemodynamic and respiratory parameters.

PMID- 29190802 TI - Perceiving the evil eye: Investigating hostile interpretation of ambiguous facial emotional expression in violent and non-violent offenders. AB - Research into the causal and perpetuating factors influencing aggression has partly focused on the general tendency of aggression-prone individuals to infer hostile intent in others, even in ambiguous circumstances. This is referred to as the 'hostile interpretation bias'. Whether this hostile interpretation bias also exists in basal information processing, such as perception of facial emotion, is not yet known, especially with respect to the perception of ambiguous expressions. In addition, little is known about how this potential bias in facial emotion perception is related to specific characteristics of aggression. In the present study, conducted in a penitentiary setting with detained male adults, we investigated if violent offenders (n = 71) show a stronger tendency to interpret ambiguous facial expressions on a computer task as angry rather than happy, compared to non-violent offenders (n = 14) and to a control group of healthy volunteers (n = 32). We also investigated if hostile perception of facial expressions is related to specific characteristics of aggression, such as proactive and reactive aggression. No clear statistical evidence was found that violent offenders perceived facial emotional expressions as more angry than non violent offenders or healthy volunteers. A regression analysis in the violent offender group showed that only age and a self-report measure of hostility predicted outcome on the emotion perception task. Other traits, such as psychopathic traits, intelligence, attention and a tendency to jump to conclusions were not associated with interpretation of anger in facial emotional expressions. We discuss the possible impact of the study design and population studied on our results, as well as implications for future studies. PMID- 29190804 TI - Virulence genes and subclone status as markers of experimental virulence in a murine sepsis model among Escherichia coli sequence type 131 clinical isolates from Spain. AB - OBJECTIVE: To assess experimental virulence among sequence type 131 (ST131) Escherichia coli bloodstream isolates in relation to virulence genotype and subclone. METHODS: We analysed 48 Spanish ST131 bloodstream isolates (2010) by PCR for ST131 subclone status (H30Rx, H30 non-Rx, or non-H30), virulence genes (VGs), and O-type. Then we compared these traits with virulence in a murine sepsis model, as measured by illness severity score (ISS) and rapid lethality (mean ISS >= 4). RESULTS: Of the 48 study isolates, 65% were H30Rx, 21% H30 non Rx, and 15% non-H30; 44% produced ESBLs, 98% were O25b, and 83% qualified as extraintestinal pathogenic E. coli (ExPEC). Of 49 VGs, ibeA and iss were associated significantly with non-H30 isolates, and sat, iha and malX with H30 isolates. Median VG scores differed by subclone, i.e., 12 (H30Rx), 10 (H30 non Rx), and 11 (non-H30) (p < 0.01). Nearly 80% of isolates represented a described virotype. In mice, H30Rx and non-H30 isolates were more virulent than H30 non-Rx isolates (according to ISS [p = 0.03] and rapid lethality [p = 0.03]), as were ExPEC isolates compared with non-ExPEC isolates (median ISS, 4.3 vs. 2.7: p = 0.03). In contrast, most individual VGs, VG scores, VG profiles, and virotypes were not associated with mouse virulence. CONCLUSIONS: ST131 subclone and ExPEC status, but not individual VGs, VG scores or profiles, or virotypes, predicted mouse virulence. Given the lower virulence of non-Rx H30 isolates, hypervirulence probably cannot explain the ST131-H30 clade's epidemic emergence. PMID- 29190805 TI - Single-molecule study of full-length NaChBac by planar lipid bilayer recording. AB - Planar lipid bilayer device, alternatively known as BLM, is a powerful tool to study functional properties of conducting membrane proteins such as ion channels and porins. In this work, we used BLM to study the prokaryotic voltage-gated sodium channel (Nav) NaChBac in a well-defined membrane environment. Navs are an essential component for the generation and propagation of electric signals in excitable cells. The successes in the biochemical, biophysical and crystallographic studies on prokaryotic Navs in recent years has greatly promoted the understanding of the molecular mechanism that underlies these proteins and their eukaryotic counterparts. In this work, we investigated the single-molecule conductance and ionic selectivity behavior of NaChBac. Purified NaChBac protein was first reconstituted into lipid vesicles, which is subsequently incorporated into planar lipid bilayer by fusion. At single-molecule level, we were able to observe three distinct long-lived conductance sub-states of NaChBac. Change in the membrane potential switches on the channel mainly by increasing its opening probability. In addition, we found that individual NaChBac has similar permeability for Na+, K+, and Ca2+. The single-molecule behavior of the full length protein is essentially highly stochastic. Our results show that planar lipid bilayer device can be used to study purified ion channels at single molecule level in an artificial environment, and such studies can reveal new protein properties that are otherwise not observable in in vivo ensemble studies. PMID- 29190806 TI - Size-conditional smolting and the response of Carmel River steelhead to two decades of conservation efforts. AB - Threshold effects are common in ecosystems and can generate counterintuitive outcomes in management interventions. A threshold effect proposed for steelhead trout (Oncorhynchus mykiss) is size-conditional smolting and marine survival. Steelhead are anadromous, maturing in the ocean but migrating to freshwater to spawn, where their offspring reside for one or more years before smolting physiologically transforming to a saltwater form-and migrating to the ocean. In conditional smolting, juveniles transform only if growth exceeds a threshold body size prior to migration season, and subsequent marine survival correlates with size at ocean entry. Conditional smolting suggests that efforts to improve freshwater survival of juveniles may reduce smolt success if they increase competition and reduce growth. Using model-selection techniques, we asked if this effect explained declining numbers of adult Carmel River steelhead. This threatened population has been the focus of two decades of habitat restoration, as well as active translocation and captive-rearing of juveniles stranded in seasonally dewatered channels. In the top-ranked model selected by information theoretic criteria, adult decline was linked to reduced juvenile growth rates in the lower river, consistent with the conditional smolting hypothesis. According to model inference, since 2005 most returning adult steelhead were captively reared. However, a lower-ranked model without conditional smolting also had modest support, and suggested a negative effect of captive rearing. Translocations of juvenile fish to perennial reaches may have reduced the steelhead run slightly by raising competition, but this effect is confounded in the data with effects of river flow on growth. Efforts to recover Carmel River steelhead will probably be more successful if they focus on conditions promoting rapid growth in the river. Our analysis clearly favored a role for size conditional smolting and marine survival in the decline of the population, but did not definitively rule out alternative explanations. PMID- 29190807 TI - Identification of BLCAP as a novel STAT3 interaction partner in bladder cancer. AB - Bladder cancer associated protein (Blcap) expression is commonly down-regulated in invasive bladder cancer, and may have prognostic value given that its expression is negatively correlated with patient survival. We have previously investigated the expression patterns and cellular localization of Blcap in bladder cancer, where we found that about 20% of the lesions examined displayed strong nuclear expression of Blcap, and that this phenotype was associated with overall poor disease outcome. Here we report on the analysis of possible functional associations between nuclear expression of Blcap and canonical signaling pathways. We performed serial immunohistochemistry (IHC) analysis of bladder tissue samples, with serial sections stained with phospho-specific antibodies recognizing key signaling intermediates, such as P-Stat3, P-Akt, and P Erk1/2, among others, in an immunophenotyping approach we have established and reported previously. Using this approach, we found that nuclear localization of Blcap was associated with expression of P-Stat3. A parallel analysis, cytokine profiling of bladder tumor interstitial fluids of samples expressing (or not) Blcap, showed interleukin (IL)-6, IL-8, and monocyte chemotactic protein 1 (MCP 1) to be correlated with nuclear expression of Blcap, independently supporting a role for Stat3 signaling in localization of Blcap. Multiple indirect immunofluorescence analysis of tissue biopsies confirmed that Blcap co-localized with Stat3. Furthermore, we could also demonstrate, using an in situ proximity ligation assay that Blcap and Stat3 are in close physical proximity of each other in bladder tissue, and that Blcap physically interacts with Stat3 as determined by co-immunoprecipitation of these proteins. Our data indicates that Blcap is a novel Stat3 interaction partner and suggests a role for Blcap in the Stat3 mediated progression of precancerous lesions to invasive tumors of the bladder. PMID- 29190808 TI - The validity of linear and non-linear heart rate metrics as workload indicators of emergency physicians. AB - BACKGROUND: It has been shown that linear and non-linear heart rate variability (HRV) metrics are suitable to assess workload of anesthetists administering anesthesia. In pre-hospital emergency care, these parameters have not yet been evaluated. We hypothesized that heart rate (HR) and HRV metrics discriminate between differing workload levels of an emergency physician. METHODS: Electrocardiograms were obtained from 13 emergency physicians. Mean HR, ten linear and seven non-linear HRV metrics were analyzed. For each sortie, four different levels of workload were defined. Mixed-effects models and the area under the receiver operating characteristics curve (AUC) were used to test and quantify the HR and HRV metrics' ability to discriminate between levels of workload. This was conducted for mean HR and each HRV metric as well as for groups of metrics (time domain vs. frequency domain vs. non-linear metrics). RESULTS: The non-linear HRV metric Permutation entropy (PeEn) discriminated best between the time before the alarm and primary patient care (AUC = 0.998, 1st rank of 18 HRV metrics). In contrast, AUC of the mean HR was low (0.558, 17th rank). In the multivariable approach, the non-linear HRV metrics provided a higher AUC (0.998) compared to the frequency domain (0.677) and to the time domain metrics (0.680). CONCLUSION: Non-linear heart rate metrics and, specifically, PeEn provided good validity for the assessment of different levels of a physician's workload in the setting of pre-hospital emergency care. In contradiction to earlier findings, the physicians' mean HR was not a valid marker of workload. PMID- 29190809 TI - Molecular diagnosis of patients with epilepsy and developmental delay using a customized panel of epilepsy genes. AB - Pediatric epilepsies are a group of disorders with a broad phenotypic spectrum that are associated with great genetic heterogeneity, thus making sequential single-gene testing an impractical basis for diagnostic strategy. The advent of next-generation sequencing has increased the success rate of epilepsy diagnosis, and targeted resequencing using genetic panels is the a most cost-effective choice. We report the results found in a group of 87 patients with epilepsy and developmental delay using targeted next generation sequencing (custom-designed Haloplex panel). Using this gene panel, we were able to identify disease-causing variants in 17 out of 87 (19.5%) analyzed patients, all found in known epilepsy associated genes (KCNQ2, CDKL5, STXBP1, SCN1A, PCDH19, POLG, SLC2A1, ARX, ALG13, CHD2, SYNGAP1, and GRIN1). Twelve of 18 variants arose de novo and 6 were novel. The highest yield was found in patients with onset in the first years of life, especially in patients classified as having early-onset epileptic encephalopathy. Knowledge of the underlying genetic cause provides essential information on prognosis and could be used to avoid unnecessary studies, which may result in a greater diagnostic cost-effectiveness. PMID- 29190810 TI - Aneurysmal subarachnoid haemorrhage (aSAH): Five consecutive years' experience of Fars province, Iran. AB - OBJECTIVE: Subarachnoid haemorrhage (SAH), caused by the rupture of intracranial aneurysms, is a devastating event with high rates of morbidity and mortality. Aneurysmal subarachnoid haemorrhage (aSAH) plays a critical role in the potential loss of life as its sufferers are usually of a young age. We aimed to investigate the incidence of aSAH along with the patients' characteristics over five consecutive years in Fars, a large province located in Southern Iran. METHODS: In this prospective study, anonymous data of all patients diagnosed with aSAH in Fars province were collected after patient admission and surgery. Data from the last national census in 2011 were used to calculate the incidence. The data were analysed using SPSS software version 18 using independent sample t test, chi square test and ANOVA. The significance level was set at 0.05. RESULTS: The number of aSAH cases identified in Fars, Iran, each year varied between 78 (2011) and 98 (2015) for a total of 421 aSAH cases within the 5-year study period. The annual aSAH incidence estimates showed no differences and were 1.65 [95% confidence interval (CI): 1.58-1.72], 1.70 (95%CI: 1.68-1.72), 1.71 (95%CI: 1.63 1.78), 1.82 (95%CI: 1.74-1.9), and 2.05 (95%CI: 1.97-2.13) per 100,000 persons, respectively, for the five consecutive years from 21 March 2011 to 20 March 2016. Hypertension was the most common risk factor, and was found in 198 (48%) aSAH patients. Ninety-four (22.5%) patients had moderate hydrocephalus on admission. Middle cerebral artery and anterior communicating artery were the most common sites of aneurysms. On admission, 351 (83%) patients had a Glasgow Coma Scale score >7, 197 (47%) presented with Hunt and Hess score of 1, and 365 (87%) had a Fisher score of <=3. Multiple aneurysms were found in 59 (14%) of the 421 cases and the most common risk factors in multiple aneurysms were hypertension in 30 (51%) and smoking in 26 (44%) cases. Survival data were available only on patients diagnosed in year 2015, and the six-month survival rate was 89.8%. CONCLUSIONS: This study revealed that although the incidence of aSAH remained stable, the survival of aSAH patients who reached the hospital alive and were operated on, improved in Shiraz (the six-month survival rate was 89.8% in year 2015). The incidence and survival study on aSAH in other geographic areas of Iran as a multi-centre study is recommended. There is a need to inform primary healthcare workers regarding the possibility of aSAH in a patient with signs of the sentinel headache. PMID- 29190812 TI - Diagnostic performance of the (1-3)-beta-D-glucan assay in patients with Pneumocystis jirovecii compared with those with candidiasis, aspergillosis, mucormycosis, and tuberculosis, and healthy volunteers. AB - BACKGROUND: Diagnosis of pneumocystis pneumonia (PCP) relies on microscopic visualization of P. jirovecii, or detection of Pneumocystis DNA in respiratory specimens, which involves invasive procedures such as bronchoalveolar lavage. The (1-3)-beta-D-glucan (BG) assay has been proposed as a less invasive and less expensive diagnostic test to rule out PCP. We therefore compared blood levels of BG in patients with PCP with those of patients with candidemia, chronic disseminated candidiasis (CDC), invasive aspergillosis, mucormycosis, and tuberculosis and those of healthy volunteers. METHODS: Adult patients who were diagnosed with PCP, candidemia, CDC, invasive aspergillosis, mucormycosis, and tuberculosis whose blood samples were available, and healthy volunteers were enrolled in a tertiary hospital in Seoul, South Korea, during a 21-month period. The blood samples were assayed with the Goldstream Fungus (1-3)-beta-D-glucan test (Gold Mountain River Tech Development, Beijing, China). RESULTS: A total of 136 individuals including 50 patients P. jirovecii,15 candidemia, 6 CDC, 15 invasive aspergillosis, 10 mucormycosis, and 40 controls (20 TB and 20 healthy volunteers) were included. The mean+/-SD of the concentration of 1-3-beta-D glucan in the patients with PCP (290.08 pg/mL+/-199.98) were similar to those of patients with candidemia (314.14 pg/mL+/-205.60, p = 0.90 at an alpha = 0.005) and CDC (129.74 pg/mL+/-182.79, p = 0.03 at an alpha = 0.005), but higher than those of patients with invasive aspergillosis (131.62 pg/mL+/-161.67, p = 0.002 at an alpha = 0.005), mucormycosis (95.08 pg/mL+/-146.80, p<0.001 at an alpha = 0.005), and tuberculosis (103.31 pg/mL+/-140.81, p<0.001 at an alpha = 0.005) as well as healthy volunteers (101.18 pg/mL+/-197.52, p<0.001 at an alpha = 0.005). At a cut-off value > 31.25 pg/mL, which is highly sensitive for PCP versus tuberculosis plus healthy volunteers at the expense of specificity, the BG assay had a sensitivity of 92% (95% CI 81%-98%) and a specificity of 55% (95% CI 39% 71%). CONCLUSIONS: The BG assay appears to be a useful adjunct test for PCP. PMID- 29190811 TI - Network dynamics of human face perception. AB - Prevailing theories suggests that cortical regions responsible for face perception operate in a serial, feed-forward fashion. Here, we utilize invasive human electrophysiology to evaluate serial models of face-processing via measurements of cortical activation, functional connectivity, and cortico cortical evoked potentials. We find that task-dependent changes in functional connectivity between face-selective regions in the inferior occipital (f-IOG) and fusiform gyrus (f-FG) are bidirectional, not feed-forward, and emerge following feed-forward input from early visual cortex (EVC) to both of these regions. Cortico-cortical evoked potentials similarly reveal independent signal propagations between EVC and both f-IOG and f-FG. These findings are incompatible with serial models, and support a parallel, distributed network underpinning face perception in humans.

AB - Flow cytometry is the primary immunological technique used to analyze multiple parameters on complex cell populations. We present a staining method that identifies major human mononuclear lymphoid and myeloid populations (CD4+ and CD8+ T cells, gammadelta T cells, B cells, NK cells and monocytes), using only two fluorochromes and a minimal number of cells. Our approach increases the number of markers recordable on most flow cytometers allowing for a deeper and more comprehensive immunophenotyping. PMID- 29190814 TI - Whole genome sequencing of Oryza sativa L. cv. Seeragasamba identifies a new fragrance allele in rice. AB - Fragrance of rice is an important trait that confers a large economic benefit to the farmers who cultivate aromatic rice varieties. Several aromatic rice varieties have limited geographic distribution, and are endowed with variety specific unique fragrances. BADH2 was identified as a fragrance gene in 2005, and it is essential to identify the fragrance alleles from diverse geographical locations and genetic backgrounds. Seeragasamba is a short-grain aromatic rice variety of the indica type, which is cultivated in a limited area in India. Whole genome sequencing of this variety identified a new badh2 allele (badh2-p) with an 8 bp insertion in the promoter region of the BADH2 gene. When the whole genome sequences of 76 aromatic varieties in the 3000 rice genome project were analyzed, the badh2-p allele was present in 13 varieties (approximately 17%) of both indica and japonica types. In addition, the badh2-p allele was present in 17 varieties that already had the loss-of-function allele, badh2-E7. Taken together, the frequency of badh2-p allele (approximately 40%) was found to be greater than that of the badh2-E7 allele (approximately 34%) among the aromatic rice varieties. Therefore, it is suggested to include badh2-p as a predominant allele when screening for fragrance alleles in aromatic rice varieties. PMID- 29190816 TI - A national survey of clinical pharmacy services in county hospitals in China. AB - BACKGROUND: Clinical pharmacy is not only a medical science but also an elaborate public health care system firmly related to its subsystems of education, training, qualification authentication, scientific research, management, and human resources. China is a developing country with a tremendous need for improvements in the public health system, including the clinical pharmacy service system. OBJECTIVES: The aim of this research was to evaluate the infrastructure and personnel qualities of clinical pharmacy services in China. SETTING: Public county hospitals in China. MATERIALS AND METHOD: A national survey of clinical pharmacists in county hospitals was conducted. It was sampled through a stratified sampling strategy. Responses were analyzed using descriptive and inferential statistics. The main outcome measures include the coverage of clinical pharmacy services, the overall staffing of clinical pharmacists, the software and hardware of clinical pharmacy services, the charge mode of clinical pharmacy services, and the educational background, professional training acquisition, practical experience, and entry path of clinical pharmacists. RESULTS: The overall coverage of clinical pharmacy services on both the department scale (median = 18.25%) and the patient scale (median = 15.38%) does not meet the 100% coverage that is required by the government. In 57.73% of the sample hospitals, the staffing does not meet the requirement, and the size of the clinical pharmacist group is smaller in larger hospitals. In addition, 23.4% of the sample hospitals do not have management rules for the clinical pharmacists, and 43.1% do not have rational drug use software, both of which are required by the government. In terms of fees, 89.9% of the sample hospitals do not charge for the services. With regard to education, 8.5% of respondents are with unqualified degree, and among respondents with qualified degree, 37.31% are unqualified in the major; 43% of respondents lack the clinical pharmacist training required by the government. Most respondents (93.5%) have a primary or medium professional title. The median age and work seniority of respondents are 31 and four years, respectively. Only 18.5% of respondents chose this occupation by personal consideration or willingness. CONCLUSIONS: The main findings in this research include the overall low coverage of clinical pharmacy services, the low rate of clinical pharmacy service software, hardware, and personnel as well as a wide variance in educational training of pharmacists at county hospitals. PMID- 29190815 TI - Aldose reductase modulates acute activation of mesenchymal markers via the beta catenin pathway during cardiac ischemia-reperfusion. AB - Aldose reductase (AR: human, AKR1B1; mouse, AKR1B3), the first enzyme in the polyol pathway, plays a key role in mediating myocardial ischemia/reperfusion (I/R) injury. In earlier studies, using transgenic mice broadly expressing human AKR1B1 to human-relevant levels, mice devoid of Akr1b3, and pharmacological inhibitors of AR, we demonstrated that AR is an important component of myocardial I/R injury and that inhibition of this enzyme protects the heart from I/R injury. In this study, our objective was to investigate if AR modulates the beta-catenin pathway and consequent activation of mesenchymal markers during I/R in the heart. To test this premise, we used two different experimental models: in vivo, Akr1b3 null mice and wild type C57BL/6 mice (WT) were exposed to acute occlusion of the left anterior descending coronary artery (LAD) followed by recovery for 48 hours or 28 days, and ex-vivo, WT and Akr1b3 null murine hearts were perfused using the Langendorff technique (LT) and subjected to 30 min of global (zero-flow) ischemia followed by 60 min of reperfusion. Our in vivo results reveal reduced infarct size and improved functional recovery at 48 hours in mice devoid of Akr1b3 compared to WT mice. We demonstrate that the cardioprotection observed in Akr1b3 null mice was linked to acute activation of the beta-catenin pathway and consequent activation of mesenchymal markers and genes linked to fibrotic remodeling. The increased activity of the beta-catenin pathway at 48 hours of recovery post-LAD was not observed at 28 days post-infarction, thus indicating that the observed increase in beta-catenin activity was transient in the mice hearts devoid of Akr1b3. In ex vivo studies, inhibition of beta-catenin blocked the cardioprotection observed in Akr1b3 null mice hearts. Taken together, these data indicate that AR suppresses acute activation of beta-catenin and, thereby, blocks consequent induction of mesenchymal markers during early reperfusion after myocardial ischemia. Inhibition of AR might provide a therapeutic opportunity to optimize cardiac remodeling after I/R injury. PMID- 29190817 TI - Screening for precancerous anal lesions with P16/Ki67 immunostaining in HIV infected MSM. AB - BACKGROUND: Screening of anal cancer in HIV-infected MSM with anal cytology results in high rates of false positive results and elevated burden of high resolution anoscopies. High-risk HPV up-regulates p16 and Ki67 expression in epithelial cells. We assessed the usefulness of P16/Ki-67 immunostaining cytology for the diagnosis of precancerous anal lesions. METHODOLOGY: Cross-sectional multicenter study. Concomitant anal liquid cytology with p16/Ki-67 immunostaining and HRA with biopsy of acetowhite lugol-negative lesions was performed in HIV infected MSM. We compared the diagnostic performance of an abnormal anal cytology and p16/Ki-67 immunostaining relative to HRA-guided biopsy by logistic regression and comparison of ROC areas. RESULTS: We included 328 HIV-infected MSM. HSIL was histologically diagnosed in 72 subjects (25.1%), and 2 (0.6%) were diagnosed with anal cancer. An abnormal cytology showed a sensitivity of 95.6% and a specificity of 58.8% for the diagnosis of biopsy-proven HSIL. P16/Ki67 positivity was associated with the presence of biopsy-proven HSIL (P trend = 0.004) but with low sensitivity (41.2%) and specificity (71%). The combination of standard cytology with P16/Ki67 immunostaining did not increment the predictive value of standard cytology alone (AUC 0.685 vs. 0.673, respectively, P = 0.688). CONCLUSION: In HIV infected MSM P16/Ki67 immunostaining does not improve the diagnostic accuracy of anal cytology, which shows a high sensitivity yet poor specificity. Other approaches aimed at improving the diagnostic accuracy of current techniques for the diagnostic of precancerous HSIL are warranted. PMID- 29190818 TI - Role of cis-trans proline isomerization in the function of pathogenic enterobacterial Periplasmic Binding Proteins. AB - Periplasmic Binding Proteins (PBPs) trap nutrients for their internalization into bacteria by ABC transporters. Ligand binding triggers PBP closure by bringing its two domains together like a Venus flytrap. The atomic determinants that control PBP opening and closure for nutrient capture and release are not known, although it is proposed that opening and ligand release occur while in contact with the ABC transporter for concurrent substrate translocation. In this paper we evaluated the effect of the isomerization of a conserved proline, located near the binding site, on the propensity of PBPs to open and close. ArgT/LAO from Salmonella typhimurium and HisJ from Escherichia coli were studied through molecular mechanics at two different temperatures: 300 and 323 K. Eight microseconds were simulated per protein to analyze protein opening and closure in the absence of the ABC transporter. We show that when the studied proline is in trans, closed empty LAO and HisJ can open. In contrast, with the proline in cis, opening transitions were much less frequent and characterized by smaller changes. The proline in trans also renders the open trap prone to close over a ligand. Our data suggest that the isomerization of this conserved proline modulates the PBP mechanism: the proline in trans allows the exploration of conformational space to produce trap opening and closure, while in cis it restricts PBP movement and could limit ligand release until in productive contact with the ABC transporter. This is the first time that a proline isomerization has been related to the control of a large conformational change like the PBP flytrap mechanism. PMID- 29190819 TI - The ectodomain of cadherin-11 binds to erbB2 and stimulates Akt phosphorylation to promote cranial neural crest cell migration. AB - During development, a multi-potent group of cells known as the cranial neural crest (CNC) migrate to form craniofacial structures. Proper migration of these cells requires proteolysis of cell adhesion molecules, such as cadherins. In Xenopus laevis, preventing extracellular cleavage of cadherin-11 impairs CNC migration. However, overexpression of the soluble cleavage product (EC1-3) is capable of rescuing this phenotype. The mechanism by which EC1-3 promotes CNC migration has not been investigated until now. Here we show that EC1-3 stimulates phosphorylation of Akt, a target of PI3K, in X.laevis CNC. Through immunoprecipitation experiments, we determined that EC1-3 interacts with all ErbB receptors, PDGFRalpha, and FGFR1. Of these receptors, only ErbB2 was able to produce an increase in Akt phosphorylation upon treatment with a recombinant EC1 3. This increase was abrogated by mubritinib, an inhibitor of ErbB2. We were able to recapitulate this decrease in Akt phosphorylation in vivo by knocking down ErbB2 in CNC cells. Knockdown of the receptor also significantly reduced CNC migration in vivo. We confirmed the importance of ErbB2 and ErbB receptor signaling in CNC migration using mubritinib and canertinib, respectively. Mubritinib and the PI3K inhibitor LY294002 significantly decreased cell migration while canertinib nearly prevented it altogether. These data show that ErbB2 and Akt are important for CNC migration and implicate other ErbB receptors and Akt independent signaling pathways. Our findings provide the first example of a functional interaction between the extracellular domain of a type II classical cadherin and growth factor receptors. PMID- 29190820 TI - Interactive effects of spectral quality and trace metal availability on the growth of Trichodesmium and Symbiodinium. AB - Light and trace metals are critical growth factors for algae but how the interdependence of light quality and metal availability affects algal growth remains largely unknown. Our previous studies have demonstrated the importance of Ni and Fe on the growth of Trichodesmium and Symbiodinium, respectively, two important marine primary producers inhabiting environments with high light intensities. Here, we investigated the effects of light quality and intensity with availability of either Ni or Fe on their growth. For Trichodesmium, we found that specific growth rates for high Ni treatments were all significantly higher than in corresponding low Ni treatments with varying light quality and intensity. The inhibitory effect of low intensity red light was also countered by sufficient Ni supply. For Symbiodinium, we found that growth rates and biomass were reduced by 75% under low intensity red light and the stress can only be partially relieved by sufficient Fe supply. The results show that trace metal availability plays an important role in relieving the stress induced by low red light condition for both Trichodesmium and Symbiodinium although the cyanobacterium performs better in this growth condition. The difference may be attributed to the presence of phycocyanin, a unique pigment attuned to absorption of red light, in Trichodesmium. Our study shows that the concerted effects of light intensity and quality compounded with trace metal availability may influence the growth of photosynthetic organisms in the ocean.

AB - Iron is an indispensable element for plant growth and defense and hence it is essential to improve the plant's ability to accumulate iron. Besides, it is also an important aspect for human health. In view of this, we attempted to increase the iron content in banana cultivar Rasthali using MusaFer1 as a candidate gene. Initially, the expression of all five genes of the MusaFer family (MusaFer1-5) was quantified under iron-excess and -deficient conditions. The supplementation of 250 and 350 MUM iron enhanced expression of all MusaFer genes; however, MusaFer1 was increased maximally by 2- and 4- fold in leaves and roots respectively. Under iron deficient condition, all five MusaFer genes were downregulated, indicating their iron dependent regulation. In MusaFer1 overexpressing lines, iron content was increased by 2- and 3-fold in leaves and roots respectively, as compared with that of untransformed lines. The increased iron was mainly localized in the epidermal regions of petiole. The analysis of MusaFer1 promoter indicated that it might control the expression of iron metabolism related genes and also other genes of MusaFer family. MusaFer1 overexpression led to downregulated expression of MusaFer3, MusaFer4 and MusaFer5 in transgenic leaves which might be associated with the plant's compensatory mechanism in response to iron flux. Other iron metabolism genes like Ferric reductase (FRO), transporters (IRT, VIT and YSL) and chelators (NAS, DMAS and NAAT) were also differentially expressed in transgenic leaf and root, suggesting the multifaceted impact of MusaFer1 towards iron uptake and organ distribution. Additionally, MusaFer1 overexpression increased plant tolerance against methyl viologen and excess iron which was quantified in terms of photosynthetic efficiency and malondialdehyde content. Thus, the study not only broadens our understanding about iron metabolism but also highlights MusaFer1 as a suitable candidate gene for iron fortification in banana.

PMID- 29190824 TI - Comparison of laser and circumlimbal suture induced elevation of intraocular pressure in albino CD-1 mice. AB - Animal models of ocular hypertension are important tools for glaucoma studies. Both acute transient models and chronic models of ocular hypertension may be useful to investigate specific aspects of neurodegeneration. In this study, we compare the intraocular pressure (IOP) and inner retinal changes induced by 1) laser photocoagulation of both episcleral veins and limbal vessels and 2) circumlimbal suture in CD-1 mice. The suture group is divided into 3 subgroups depending on the level of the immediate IOP spike (acute > 55 mmHg or chronic < 55 mmHg) and time period of monitoring (7 or 28 days). The laser group is followed for 7 days. IOP data show that it peaks at 5 hours and returns to normal level within 7 days in the laser group. In all suture groups, IOP spikes initially and decreases gradually, but it remains significantly elevated at 7 days. In 7 days, the acute suture model generates rapid loss of retinal nerve fiber layer (RNFL) and retinal ganglion cells (RGCs) when compared to the gradual loss by the chronic suture model, possibly due to retinal ischemia and reperfusion within the first few hours after treatment. The laser model falls between the acute suture and chronic suture models resulting in less RNFL and RGC loss than the acute suture model but significantly more loss than the chronic suture model. These results suggest that when using suture models of IOP elevation, it is critical to take the initial IOP spike into consideration and to choose between the acute and chronic models depending on respective research purposes. PMID- 29190822 TI - The tumor suppressor phosphatase PP2A-B56alpha regulates stemness and promotes the initiation of malignancies in a novel murine model. AB - Protein phosphatase 2A (PP2A) is a ubiquitously expressed Serine-Threonine phosphatase mediating 30-50% of protein phosphatase activity. PP2A functions as a heterotrimeric complex, with the B subunits directing target specificity to regulate the activity of many key pathways that control cellular phenotypes. PP2A B56alpha has been shown to play a tumor suppressor role and to negatively control c-MYC stability and activity. Loss of B56alpha promotes cellular transformation, likely at least in part through its regulation of c-MYC. Here we report generation of a B56alpha hypomorph mouse with very low B56alpha expression that we used to study the physiologic activity of the PP2A-B56alpha phosphatase. The predominant phenotype we observed in mice with B56alpha deficiency in the whole body was spontaneous skin lesion formation with hyperproliferation of the epidermis, hair follicles and sebaceous glands. Increased levels of c-MYC phosphorylation on Serine62 and c-MYC activity were observed in the skin lesions of the B56alphahm/hm mice. B56alpha deficiency was found to increase the number of skin stem cells, and consistent with this, papilloma initiation was accelerated in a carcinogenesis model. Further analysis of additional tissues revealed increased inflammation in spleen, liver, lung, and intestinal lymph nodes as well as in the skin lesions, resembling elevated extramedullary hematopoiesis phenotypes in the B56alphahm/hm mice. We also observed an increase in the clonogenicity of bone marrow stem cells in B56alphahm/hm mice. Overall, this model suggests that B56alpha is important for stem cells to maintain homeostasis and that B56alpha loss leading to increased activity of important oncogenes, including c-MYC, can result in aberrant cell growth and increased stem cells that can contribute to the initiation of malignancy.

AB - During routine monitoring of commercial purse seine catches in 2011, 87 fingerling specimens of scombrids were collected in the southern Adriatic Sea. Sequencing of the mitochondrial DNA control region locus inferred that specimens belonged to the Atlantic bluefin tuna, Thunnus thynnus (Linnaeus, 1758) (N = 29), bullet tuna, Auxis rochei (Risso, 1810) (N = 30) and little tunny, Euthynnus alletteratus, Rafinesque, 1810 (N = 28). According to previously published growth parameters, the age of the collected specimens was estimated at approximately 30 40 days, suggesting they might have been spawned in the Adriatic Sea, contrary to the current knowledge. A coupled modelling system with hydrodynamic (ROMS) and individual based model (IBM-Ichthyop) was set up to determine the location of the spawning event. Numerical simulations with the IBM model, both backward and forward in time, indicate commercial tuna cages in the middle Adriatic coastal area as possible spawning location. The two other non-commercial species likely opportunistically use the positive environmental (abiotic and biotic) conditions to spawn in the same area. PMID- 29190826 TI - Biological responses of the marine diatom Chaetoceros socialis to changing environmental conditions: A laboratory experiment. AB - Diatoms constitute a major group of phytoplankton, accounting for ~20% of the world's primary production. It has been shown that iron (Fe) can be the limiting factor for phytoplankton growth, in particular, in the HNLC (High Nutrient Low Chlorophyll) regions. Iron plays thus an essential role in governing the marine primary productivity and the efficiency of biological carbon pump. Oceanic systems are undergoing continuous modifications at varying rates and magnitudes as a result of changing climate. The objective of our research is to evaluate how changing environmental conditions (dust deposition, ocean warming and acidification) can affect marine Fe biogeochemistry and diatom growth. Laboratory culture experiments using a marine diatom Chaetoceros socialis were conducted at two temperatures (13 degrees C and 18 degrees C) and under two pCO2 (carbon dioxide partial pressure) (400 MUatm and 800 MUatm) conditions. The present study clearly highlights the effect of ocean acidification on enhancing the release of Fe upon dust deposition. Our results also confirm that being a potential source of Fe, dust provides in addition a readily utilizable source of macronutrients such as dissolved phosphate (PO4) and silicate (DSi). However, elevated atmospheric CO2 concentrations may also have an adverse impact on diatom growth, causing a decrease in cell size and possible further changes in phytoplankton composition. Meanwhile, ocean warming may lead to the reduction of diatom production and cell size, inducing poleward shifts in the biogeographic distribution of diatoms. The changing climate has thus a significant implication for ocean phytoplankton growth, cell size and primary productivity, phytoplankton distribution and community composition, and carbon (C), nitrogen (N), phosphorus (P), silicon (Si) and Fe biogeochemical cycles in various ways.

PMID- 29190827 TI - Intra-venous bevacizumab in hereditary hemorrhagic telangiectasia (HHT): A retrospective study of 46 patients. AB - BACKGROUND: Bevacizumab, an anti-VEGF monoclonal antibody, has recently emerged as a new option for severe forms of hereditary hemorrhagic telangiectasia (HHT). Its utilization in this orphan disease has rapidly spread despite the lack of randomized trials and international guidelines. The objective of this study is to report the main clinical data (baseline characteristics, dose schedule, efficacy, adverse events and deaths) of HHT patients treated by intravenous bevacizumab in France. METHODS: Retrospective observational study of HHT patients treated with bevacizumab for a severe form of the disease in the 14 centers of the French HHT network. RESULTS: Forty-six patients (median age: 68 years) were treated between March 2009 and May 2015. Ten patients were treated for high output cardiac failure, 20 patients for severe hemorrhages and 16 for both indications. The standard protocol (6 infusions of 5mg/kg every 2 weeks) was initially used in 89% of the cases but diverse strategies were subsequently applied. A clinical improvement was noted by the referent physician for 74% of the patients with a median effect's duration of 6 months. Wound healing complications led to 2 amputations. Arthralgia/arthritis and arterial hypertension occurred in 5 patients each. One third of the patients were dead at the time of the final update, coherently with age and the poor prognosis of these highly symptomatic patients. CONCLUSION: Intravenous bevacizumab seems to provide a clinical benefice in severe HHT patients. Precautions concerning wound healing and vascular pathologies must be respected. Prospective double blinded versus placebo trials are needed. PMID- 29190829 TI - A comprehensive analysis of breast cancer microbiota and host gene expression. AB - The inflammatory tumoral-immune response alters the physiology of the tumor microenvironment, which may attenuate genomic instability. In addition to inducing inflammatory immune responses, several pathogenic bacteria produce genotoxins. However the extent of microbial contribution to the tumor microenvironment biology remains unknown. We utilized The Cancer Genome Atlas, (TCGA) breast cancer data to perform a novel experiment utilizing unmapped and mapped RNA sequencing read evidence to minimize laboratory costs and effort. Our objective was to characterize the microbiota and associate the microbiota with the tumor expression profiles, for 668 breast tumor tissues and 72 non-cancerous adjacent tissues. The prominent presence of Proteobacteria was increased in the tumor tissues and conversely Actinobacteria abundance increase in non-cancerous adjacent tissues. Further, geneset enrichment suggests Listeria spp to be associated with the expression profiles of genes involved with epithelial to mesenchymal transitions. Moreover, evidence suggests H. influenza may reside in the surrounding stromal material and was significantly associated with the proliferative pathways: G2M checkpoint, E2F transcription factors, and mitotic spindle assembly. In summary, further unraveling this complicated interplay should enable us to better diagnose and treat breast cancer patients. PMID- 29190831 TI - Erectile dysfunction and quality of life in men receiving methadone or buprenorphine maintenance treatment. A cross-sectional multicentre study. AB - BACKGROUND: Erectile dysfunction (ED) is common among men on opioid replacement therapy (ORT), but most previous studies exploring its prevalence and determinants yielded contrasting findings. Moreover, the impact of ED on patients' quality of life (QoL) has been seldom explored. OBJECTIVE: To explore the prevalence and determinants of ED in men on ORT, and the impact on QoL. METHODS: In a multicentre cross-sectional study, we recruited 797 consecutive male patients on methadone and buprenorphine treatment, collected data on demographic, clinical, and psychopathological factors, and explored their role as predictors of ED and QoL through univariate and multivariate analysis. ED severity was assessed with a self-assessment questionnaire. RESULTS: Nearly half of patients in our sample were sexually inactive or reported some degree of ED. Some demographic, clinical and psychopathological variables significantly differed according to the presence or absence of ED. Multivariate regression analysis indicated that age, employment, smoke, psychoactive drugs, opioid maintenance dosage, and severity of psychopathological factors significantly influenced the risk and severity of ED. QoL was worse in patients with ED and significantly correlated with ED severity. Age, education, employment, opioid maintenance dosage, ED score, and severity of psychopathology significantly influenced QoL in the multivariate analysis. CONCLUSIONS: ED complaints can be explored in male opioid users on ORT through a simple and quick self-assessment tool. ED may have important effects on emotional and social well-being, and may affect outcome. PMID- 29190830 TI - Reduced functional connectivity of fronto-parietal sustained attention networks in severe childhood abuse. AB - Childhood maltreatment is associated with attention deficits. We examined the effect of childhood abuse and abuse-by-gene (5-HTTLPR, MAOA, FKBP5) interaction on functional brain connectivity during sustained attention in medication/drug free adolescents. Functional connectivity was compared, using generalised psychophysiological interaction (gPPI) analysis of functional magnetic resonance imaging (fMRI) data, between 21 age-and gender-matched adolescents exposed to severe childhood abuse and 27 healthy controls, while they performed a parametrically modulated vigilance task requiring target detection with a progressively increasing load of sustained attention. Behaviourally, participants exposed to childhood abuse had increased omission errors compared to healthy controls. During the most challenging attention condition abused participants relative to controls exhibited reduced connectivity, with a left-hemispheric bias, in typical fronto-parietal attention networks, including dorsolateral, rostromedial and inferior prefrontal and inferior parietal regions. Abuse-related connectivity abnormalities were exacerbated in individuals homozygous for the risky C-allele of the single nucleotide polymorphism rs3800373 of the FK506 Binding Protein 5 (FKBP5) gene. Findings suggest that childhood abuse is associated with decreased functional connectivity in fronto-parietal attention networks and that the FKBP5 genotype moderates neurobiological vulnerability to abuse. These findings represent a first step towards the delineation of abuse related neurofunctional connectivity abnormalities, which hopefully will facilitate the development of specific treatment strategies for victims of childhood maltreatment. PMID- 29190832 TI - Low level of polyandry constrains phenotypic plasticity of male body size in mites. AB - Polyandry, i.e. females mating with multiple males, is more common than previously anticipated and potentially provides both direct and indirect fitness benefits to females. The level of polyandry (defined by the lifetime number of male mates of a female) is an important determinant of the occurrence and intensity of sexual selection acting on male phenotypes. While the forces of sexual selection acting on phenotypic male traits such as body size are relatively well understood, sexual selection acting on phenotypic plasticity of these traits is unexplored. We tackled this issue by scrutinizing the link between polyandry and phenotypic plasticity of male body size in two sympatric plant-inhabiting predatory mite species, Phytoseiulus persimilis and Neoseiulus californicus. These two species are similar in life history, ecological niche requirements, mating behavior, polygyny and female body size plasticity but strikingly differ in the level of both polyandry and phenotypic plasticity of male body size (both lower in P. persimilis). We hypothesized that deviations from standard body size, i.e. the size achieved under favorable conditions, incur higher costs for males in the less polyandrous P. persimilis. To test our hypotheses, we conducted two experiments on (i) the effects of male body size on spermatophore transfer in singly mating females and (ii) the effects of mate sequence (switching the order of standard-sized and small males) on mating behavior and paternity success in doubly mating females. In P. persimilis but not N. californicus, small males transferred fewer but larger spermatophores to the females; in both species, females re-mated more likely with standard-sized following small than small following standard-sized males; in P. persimilis, first standard-sized males sired a higher proportion of offspring produced after re-mating by the female than first small males, whereas in N. californicus the paternity success of small and standard-sized males was independent of the mating sequence. Based on our results and pertinent previous studies, which showed that females of P. persimilis, but not N. californicus, prefer mating with standard sized over small males and allow them fertilizing more eggs, the lack of interspecific difference in female body size plasticity, and the absence of any clue pointing at a role of natural selection, we suggest that the interspecific difference in male body size plasticity is sexually selected. Our study provides an indication of sexual selection constraining plasticity of male phenotypes, suggesting that the level of polyandry may be an important co-determinant of the level of phenotypic plasticity of male body size. PMID- 29190833 TI - Lupus nephritis progression in FcgammaRIIB-/-yaa mice is associated with early development of glomerular electron dense deposits and loss of renal DNase I in severe disease. AB - FcgammaRIIB-/-yaa mice develop severe lupus glomerulonephritis due to lack of an inhibitory immune cell receptor combined with a Y-chromosome linked autoimmune accelerator mutation. In the present study, we have investigated nephritis development and progression in FcgammaRIIB-/-yaa mice to find shared features with NZB/NZW F1 lupus prone mice and human disease. We sacrificed 25 male FcgammaRIIB-/-yaa mice at various disease stages, and grouped them according to activity and chronicity indices for lupus nephritis. Glomerular morphology and localization of electron dense deposits containing IgG were further determined by immune electron microscopy. Renal DNase I and pro-inflammatory cytokine mRNA levels were measured by real-time quantitative PCR. DNase I protein levels was assessed by immunohistochemistry and zymography. Our results demonstrate early development of electron dense deposits containing IgG in FcgammaRIIB-/-yaa mice, before detectable levels of serum anti-dsDNA antibodies. Similar to NZB/NZW F1, electron dense deposits in FcgammaRIIB-/-yaa progressed from being confined to the mesangium in the early stage of lupus nephritis to be present also in capillary glomerular basement membranes. In the advanced stage of lupus nephritis, renal DNase I was lost on both transcriptional and protein levels, which has previously been shown in NZB/NZW F1 mice and in human disease. Although lupus nephritis appears on different genetic backgrounds, our findings suggest similar processes when comparing different murine models and human lupus nephritis. PMID- 29190834 TI - Ephrin-B2 reverse signaling regulates progression and lymph node metastasis of oral squamous cell carcinoma. AB - Oral squamous cell carcinoma (OSCC) is a common malignant tumor of the head and neck and frequently metastasizes to cervical lymph nodes. Aggressive local invasion and metastasis of OSCC are significant factors for poor prognosis. In this study, we investigated whether ephrin-B2 expressed in OSCC contributed to tumor progression and lymph node metastasis. Clinical specimens from patients with OSCC had robust ephrin-B2-positive tumor cells and ephrin-B2 protein level was associated with clinical stage, lymph node metastasis, and poor survival outcomes. We also determined that ephrin-B2 protein level was increased in OSCC cell lines compared to normal human oral keratinocytes and that its levels were associated with the migratory and invasive potential of OSCC cell lines. Transfection of an EFNB2-specific small interfering RNA (siRNA) into SAS-L1 cells significantly reduced proliferation, attachment, migration, and invasion through phosphorylation of the epidermal growth factor receptor, FAK, ERK1/2, p38, AKT, and JNK1/2 pathways. Furthermore, knockdown of EFNB2 significantly suppressed adhesion and transmigration of SAS-L1 cells toward human lymphatic endothelial cells. In addition, the growth rate of tumor xenografts and cervical lymph node metastases of OSCC were suppressed by local injection of EFNB2 siRNA. These results suggest that ephrin-B2 overexpression and activation of the ephrin-B2 reverse signaling pathway in tumor microenvironment in OSCC facilitates progression and lymph node metastasis via enhancement of malignant potential and interaction with surrounding cells.

AB - Falls are the leading cause of emergency department (ED) visits for fatal and non fatal injuries among adults 65 years old and older. We aimed to better understand the fall history, risk for further falls, and actions taken to prevent further falls among this higher fall risk population. This cross-sectional study included older adults without cognitive impairment presenting to the Rhode Island Hospital ED from February to May 2017. Of the 76 participants, 35 self-reported no prior falls, and 41 self-reported at least one prior fall, of whom 20 fell on the day of ED presentation. Participants with vs. without self-reported prior falls were similar in age, gender, race, and substance use. Participants with prior falls scored lower on cognitive testing and had more comorbidities associated with falls. Only one quarter of those with prior falls reported making changes and few were evaluated by professionals to prevent future falls. This study highlights that older adult ED patients who sustain a fall are at higher risk for subsequent falls, and that greater fall prevention efforts are needed to protect this vulnerable group.

PMID- 29190839 TI - Violence Against Women: Injuries and Deaths in Rhode Island Yongwen Jiang, PhD; Deborah Debare, MMHS; Lynne-Marie Shea, BA; Samara Viner-Brown, MS. AB - Violence against women is a public health issue. Monitoring assault-related injury and homicide death among women is imperative for understanding this public health issue. We used data from the 2014 Rhode Island emergency department (ED), hospital discharge (HD), and 2004-2014 Rhode Island violent death reporting system (RIVDRS) to provide a broad picture for violence against women injuries and deaths in Rhode Island. ED visit and HD data show that the majority of female assault injuries occurred among women aged 25-44, resided in the core cities, and had public insurance. RIVDRS data showed that over half of the homicides among women were aged 25-64; nearly two in five were non-Hispanic black or Hispanic. Precipitating circumstances include intimate partner violence, a preceding argument or a conflict, and precipitated by another crime. Evidence-informed interventions need to target high-risk populations and urban areas to effectively reduce violence against women.

AB - Using editorials published in the Rhode Island Medical Journal's inaugural year, this article examines what it meant to practice medicine in Rhode Island in 1917. One hundred years ago, the state's medical community was undergoing rapid transformation epitomized by a turn toward the germ theory of disease, ongoing education and hospital reform, and a growing sense of the profession's political and social role. In many ways, the social and professional concerns of Rhode Island physicians in 1917 continue to resonate today. Physicians writing in the Journal were excited by but concerned about technological advancement in medicine, debating how new institutions and sites of care would shape their interactions with patients. They were also influenced by broader social changes affecting the medical profession, expressing ambivalence toward regulation, debating the implications of social insurance and compulsory health insurance, and reflecting on their financial livelihood and the social prestige of their profession.

AB - OBJECTIVE: Twin pregnancies are associated with an increased risk of spontaneous preterm birth. Our objective was to compare the performance of uterocervical angle to cervical length as predictors of spontaneous preterm birth in this population. METHODS: We conducted a retrospective cohort study of twin gestations at a single center from May 2008 to 2016 who received a transvaginal ultrasound for the evaluation of the cervix between 16 0/7 and 23 0/7 weeks. The primary outcome was prediction of preterm birth <28 and <32 weeks by uterocervical angle and cervical length. RESULTS: Among 259 women with twin gestation, the mean gestational age at birth was 34.83 +/- 3.48 weeks. Receiver operator characteristic curves demonstrated optimal prediction of spontaneous preterm birth prior to 32 weeks at a uterocervical angle >110 degrees (80% sensitivity, 82% specificity) [odds ratio (OR), 15.7 (95% confidence interval (CI), 7.2-34.4)] versus cervical length <20 mm (53% sensitivity, 85% specificity; p < 0.001, OR, 6.4 [95% CI, 2.3-17.8]) and similarly, prior to 28 weeks at a uterocervical angle >114 degrees (OR, 24.3 [95% CI, 6.7-88.5]) compared with cervical length <20 mm (OR, 11.4 [95% CI, 3.5-36.7]). CONCLUSION: Uterocervical angles >110 degrees performed better than cervical length for the prediction of spontaneous preterm birth in twin gestations. PMID- 29190845 TI - Nasogastric Feeding Tubes May Not Contribute to Gastroesophageal Reflux in Preterm Infants. AB - OBJECTIVE: The objective was to determine if the presence of a nasogastric (NG) feeding tube is associated with increased gastroesophageal reflux (GER) and acid exposure in preterm infants. STUDY DESIGN: This is a retrospective study on preterm infants [gestational age (GA) <37 weeks] who were evaluated by multichannel intraluminal impedance and pH monitoring (MII-pH) between October 2009 and March 2016. Infants were divided into two groups, NG tube present and no feeding tube. GER events per hour and the percent of time with pH <4 during a 24 hour period were then compared. RESULTS: Eighty-three infants were included, 41 had an NG tube present and 42 did not. The group without an NG tube had significantly more reflux events per hour (2.3 +/- 2.9 vs. 1.3 +/- 0.8, p < 0.05) even after adjusting for differences in birth weight, GA, corrected GA, and total fluid intake. There was no significant difference in acidic events per hour and acid exposure time between the two groups. CONCLUSION: The presence of a 5 French NG tube is not associated with an increase in GER or acid exposure in preterm infants. In fact, it appears that infants fed through an NG tube have fewer episodes of GER. PMID- 29190846 TI - Characterization of Thermal and Mechanical Indices from Serial Ultrasound Exams and Associations with Neonatal Anthropometry: The NICHD Fetal Growth Studies. AB - OBJECTIVE: This article aims to determine if the number of maternal ultrasound scans where the highest thermal (TI) or mechanical (MI) indices recorded during obstetrical ultrasound exceed 1.0 were associated with neonatal anthropometric measurements. STUDY DESIGN: A prospective cohort of 2,334 nonobese low-risk pregnant women from 12 U.S. clinical sites underwent a total of six ultrasound scans, for which the highest TI and MI values were recorded. Neonatal anthropometric measurements were obtained within 12 to 24 hours of delivery. Multiple linear regression models adjusted for maternal race/ethnicity, body mass index, weight gain, and gestational age were used to examine associations between the number of maternal ultrasounds during gestation with a TI or MI exceeding 1.0 and the mean change in neonatal anthropometry. RESULTS: Ultrasounds with TI or MI >1.0 were not associated with birth weight, neonatal length, nor head, chest, and abdominal circumferences. TI >1.0 was negatively associated with neonatal mid upper arm and mid-upper thigh circumferences. MI >1.0 was negatively associated with neonatal skinfold measurements of the anterior thigh and triceps, and neonatal circumferences of the mid-upper thigh and umbilicus. CONCLUSION: Prenatal ultrasound examinations in which TI or MI intermittently exceeded 1.0 did not identify a pattern of alterations of birth size. PMID- 29190848 TI - Temporal Relationship of Onset of Necrotizing Enterocolitis and Introduction of Enteric Feedings and Powdered Milk Fortifier. AB - OBJECTIVE: This article evaluates temporal relationships between onset of necrotizing enterocolitis (NEC) in preterm infants and introduction of enteral feedings or powdered human milk fortifier (HMF). STUDY DESIGN: This is a Poisson regression analysis of NEC cases at a single children's hospital between 1999 and 2009, using the self-controlled case series method to estimate adjusted daily event rate ratios (DERR) during postexposure intervals. RESULTS: Of 139 patients with a clinical diagnosis of NEC, 26 had early disease onset prior to initiation of feeding and were considered to be cases of spontaneous intestinal perforation (SIP). For the remaining 113 infants, the DERR for NEC onset were significantly greater on days for which infants were <14 days of age (DERR, 2.15; 95% confidence interval [CI], 1.22-3.79) or >=31 weeks postmenstrual age (2.94; 95% CI, 1.51-5.83) or which fell within 14 days after initiation of enteric feeding (8.29; 95% CI, 4.73-14.53) or 4 days after introduction of HMF (12.32; 95% CI, 7.13-21.29). CONCLUSION: There are strong temporal associations between onset of NEC and initiation of enteral feeding or powdered HMF in preterm infants. PMID- 29190847 TI - Adverse Maternal and Neonatal Outcomes in Indicated Compared with Spontaneous Preterm Birth in Healthy Nulliparas: A Secondary Analysis of a Randomized Trial. AB - OBJECTIVE: To compare the risks of adverse maternal and neonatal outcomes associated with spontaneous (SPTB) versus indicated preterm births (IPTB). METHODS: A secondary analysis of a multicenter trial of vitamin C and E supplementation in healthy low-risk nulliparous women. Outcomes were compared between women with SPTB (due to spontaneous membrane rupture or labor) and those with IPTB (due to medical or obstetric complications). A primary maternal composite outcome included: death, pulmonary edema, blood transfusion, adult respiratory distress syndrome (RDS), cerebrovascular accident, acute tubular necrosis, disseminated intravascular coagulopathy, or liver rupture. A neonatal composite outcome included: neonatal death, RDS, grades III or IV intraventricular hemorrhage (IVH), sepsis, necrotizing enterocolitis (NEC), or retinopathy of prematurity. RESULTS: Of 9,867 women, 10.4% (N = 1,038) were PTBs; 32.7% (n = 340) IPTBs and 67.3% (n = 698) SPTBs. Compared with SPTB, the composite maternal outcome was more frequent in IPTB-4.4% versus 0.9% (adjusted odds ratio [aOR], 4.0; 95% confidence interval [CI], 1.4-11.8), as were blood transfusion and prolonged hospital stay (3.2 and 3.7 times, respectively). The frequency of composite neonatal outcome was higher in IPTBs (aOR, 1.8; 95% CI, 1.1-3.0), as were RDS (1.7 times), small for gestational age (SGA) < 5th percentile (7.9 times), and neonatal intensive care unit (NICU) admission (1.8 times). CONCLUSION: Adverse maternal and neonatal outcomes were significantly more likely with IPTB than with SPTB. PMID- 29190849 TI - Concussion Recovery Phase Affects Vestibular and Oculomotor Symptom Provocation. AB - Vestibular and oculomotor testing is emerging as a valuable assessment in sport related concussion (SRC). However, their usefulness for tracking recovery and guiding return-to-play decisions remains unclear. Therefore the purpose of this study was to evaluate their clinical usefulness for tracking SRC recovery. Vestibular and oculomotor assessments were used to measure symptom provocation in an acute group (n=21) concussed<=10 days, prolonged symptoms group (n=10) concussed >=16 days (median=84 days), healthy group (n=58) no concussions in >6 months. Known-groups approach was used with three groups at three time points (initial, 2-week and 6-week follow-up). Provoked symptoms for Gaze-Stabilization (GST), Rapid Eye Horizontal (REH), Optokinetic Stimulation (OKS), Smooth-Pursuit Slow (SPS) and Fast (SPF) tests, total combined symptoms scores and near point convergence (NPC) distance were significantly greater at initial assessment in both injury groups compared to controls. Injury groups improved on the King Devick test and combined symptom provocation scores across time. The acute group improved over time on REH and SPF tests, while the prolonged symptoms group improved on OKS. A regression model (REH, OKS, GST) was 90% accurate discriminating concussed from healthy. Vestibular and ocular motor tests give valuable insight during recovery. They can prove beneficial in concussion evaluation given the modest equipment, training and time requirements. The current study demonstrates that when combined, vestibular and oculomotor clinical tests aid in the detection of deficits following a SRC. Additionally, tests such as NPC, GST, REH, SPS, SPF OKS and KD provide valuable information to clinicians throughout the recovery process and may aid in return to play decisions. PMID- 29190850 TI - MRI Cartilage Assessment of the Subtalar and Midtarsal Joints During a Transcontinental Ultramarathon - New Insights into Human Locomotion. AB - MR measurements can be accurately performed during 4486 km of running, opening a window into in vivo assessment of hindfoot articular cartilage under extreme ultra-endurance loading. This observational cross-sectional study included 22 randomized participants of TransEurope FootRace between Italy and the North Cape, which was accompanied by a trailer-mounted 1.5T MRI scanner over 9 weeks. Four follow up MR examinations of subtalar and midtarsal joints were performed. Statistics of cartilage T2* and thickness were obtained. Nearly all observed joints showed an initial significant mean T2* increase of 20.9% and 26.3% for the left and right side, followed by a relative decrease of 28.5% and 16.0% during the second half, respectively. It could be demonstrated that mobile MRI field studies allow in vivo functional tissue observations under extreme loading. Elevated T2* values recovered during the second half of the ultramarathon supported the evidence that this response is a physiological adaptive mechanism of chondrocyte function via upregulation of de novo synthesis of proteoglycans and collagen. These changes occurred in a distinct asymmetric pattern leaving a "biochemical signature" of articular cartilage that allows in vivo insight into joint loading. In conclusion, the normal articular cartilage of the hindfoot is resilient and adaptive, leaving extreme endurance activities up to limitless human ambition. PMID- 29190851 TI - Oxidized Low-Density Lipoprotein and Cell Adhesion Molecules Following Exercise Training. AB - Elevated oxidized low-density lipoprotein (ox-LDL) and cell adhesion molecules are associated with inflammation and atherosclerosis. The role of exercise in circulating ox-LDL, enzyme mediators, and cell adhesion molecules are not clearly understood in obesity. As a randomized controlled design, 27 obese (BMI>30 kg/m2) sedentary men (N=13) and women (N=14) were randomly assigned to either an exercise (N=15) or a control (N=12) group. The exercise group performed a 60-min supervised treadmill exercise at moderate intensity (70% of HRmax) for 3 days per week for 4 weeks, while the control group did not exercise. Overnight fasting blood samples were collected before and after the study period to analyze serum lipids, lipoprotein-cholesterol, ox-LDL, 12- and 15-lipoxygenases, myeloperoxidase (MPO), and soluble vascular cell adhesion molecules-1 and intercellular adhesion molecule-1. Moderate-intensity exercise training lowered both ox-LDL (from 44.76+/-1.99 to 38.51+/-1.99 U/L, p=0.032) and MPO (from 31.48+/-2.20 to 23.09+/-2.20 ng/mL, p=0.010), without significantly altering body weight, other parameters of serum lipids and lipoproteins, or soluble cell adhesion molecules. Moderate intensity exercise training reduced the levels of ox LDL and MPO, indicating a reduced risk for developing CVD and additional protection to the possible metabolic complications associated with obesity. PMID- 29190852 TI - Exercise Prescription Using the Borg Rating of Perceived Exertion to Improve Fitness. AB - The present study aimed to compare two fitness-training methodologies, instability circuit resistance training (ICRT) versus traditional circuit resistance training (TCRT), applying an experimental model of exercise prescription controlling and modulating exercise load using the Borg rating of perceived exertion. Forty-four healthy young adults age (21.6+/-2.3 years) were randomly assigned to three groups: TCRT (n=14), ICRT (n=14) and a control group (n=16). Strength and cardiorespiratory tests were chosen to evaluate cardiorespiratory and muscular fitness before and after the training program. In cardiorespiratory data, a significant difference was observed for the time effect in VO2max, peak heart rate, peak velocity, and heart rate at anaerobic threshold intensity (p<0.05) in the experimental groups. In strength variables, a significant Group x Time interaction effect was detected in 1RM, in mean propulsive power, and in peak power (p<=0.01) in the back squat exercise. In the bench press exercise, a significant time effect was detected in 1RM, in mean propulsive power, and in peak power, and a Group x Time interaction in peak power (all p<0.05). We can conclude that applying an experimental model of exercise prescription using RPE improved cardiorespiratory and muscular fitness in healthy young adults in both experimental groups. PMID- 29190853 TI - Contributions of Hamstring Stiffness to Straight-Leg-Raise and Sit-and-Reach Test Scores. AB - The passive straight-leg-raise (PSLR) and the sit-and-reach (SR) tests have been widely used to assess hamstring extensibility. However, it remains unclear to what extent hamstring stiffness (a measure of material properties) contributes to PSLR and SR test scores. Therefore, we aimed to clarify the relationship between hamstring stiffness and PSLR and SR scores using ultrasound shear wave elastography. Ninety-eight healthy subjects completed the study. Each subject completed PSLR testing, and classic and modified SR testing of the right leg. Muscle shear modulus of the biceps femoris, semitendinosus, and semimembranosus was quantified as an index of muscle stiffness. The relationships between shear modulus of each muscle and PSLR or SR scores were calculated using Pearson's product-moment correlation coefficients. Shear modulus of the semitendinosus and semimembranosus showed negative correlations with the two PSLR and two SR scores (absolute r value<=0.484). Shear modulus of the biceps femoris was significantly correlated with the PSLR score determined by the examiner and the modified SR score (absolute r value<=0.308). The present findings suggest that PSLR and SR test scores are strongly influenced by factors other than hamstring stiffness and therefore might not accurately evaluate hamstring stiffness. PMID- 29190854 TI - [Clostridium difficile Infection: Epidemiology, Clinical Presentation, Therapy and Prevention]. AB - Clostridium difficile infections (CDI) are common causes of diarrhoea in hospitalised medical and surgical patients. Clinical presentation ranges from mild diarrhoea to pseudomembraneous enterocolitis of the colon and sometimes the small intestines, with development of a toxic megacolon. Recurrent infections are common. Early diagnosis is necessary because of high rates of complications and mortality. Knowledge of risk factors for the development of CDI is recommended. Early initiation of therapy is recommended to avoid complications and standard therapy is antibiotics, while therapy with monoclonal antibodies and vaccination is under research and development. Fulminant septic courses indicate surgical source control. Minimally invasive surgical therapy establishing a loop ileostomy and antibiotic installation via enema has to be considered as early surgical intervention. Fecal microbiotic transplantation is a new therapeutic option for recurrent infection. Provisions for prevention and control have to be established to avoid in-hospital spread of pathogenic agents. This includes isolation of patients, personalisation of instruments, restriction of in-hospital transports, protective clothing and gloves, strict hand washing and antibiotic stewardship (ABS). PMID- 29190856 TI - Evaluation of Paclitaxel Nanocrystals In Vitro and In Vivo. AB - We created a novel paclitaxel (PTX) nanoparticle drug delivery system and compared this to acommercial injection preparation to evaluate the antitumor effects for both formulations in vivo and in vitro.PTXnanocrystals were 194.9 nm with potential of -29.6 mV. Cytotoxicity tests indicated that both formulations had similar effects and cytotoxicity was dose- and time dependent.Pharmacodynamics indicated that the drug concentration at the tumor was greater with PTX nanocrystals compared to commercial injection (P<0.01) and that drug accumulated more and for a longer duration. In vivo antitumor evaluation indicated significant antitumor effects and low toxicity of PTX nanocrystals. Moreover, bioimaging indicated that the PTX retention time in MCF-7-bearing mice was longer, especially at the tumor site, and this high drug concentration was maintained for a long time.Overall, PTX nanocrystalsare feasible and superior to traditional injection formulation chemotherapy. PMID- 29190855 TI - Efficacy of Lophira alata Leaf Extract and its Combination with Artesunate in Mice Prior Exposed to Plasmodium berghei. AB - Enhanced antimalarial activity of plant extracts used for treatment of malaria in endemic areas is attributed to partial immunity gained by prior infection. This suggests synergy between immunity and extract activity in treatment. Testing this hypothesis, rodent malaria was used to determine efficacy of Lophira alata leaf extracts in treating malaria in prior infected mice. One round of P. berghei infection and Pyrimethamine drug-cure was used to establish partial immunity in mice. Previously Exposed Mice (PEM) and Previously Unexposed Mice (PUM) mice challenged with P. berghei were used to determine influence of partial antimalarial immunity on efficacy of L. alata leaf extracts, administered alone or in combination with Artesunate (ART) in malaria treatment. There was a significant reduction in parasitemia in PEM when compared to PUM animals (P<0.001) irrespective of treatment regimen. Administration of L. alata combined with ART significantly reduced parasitemia (P<0.0032) and prolonged (P=0.0109) survival than when L. alata was administered alone in infected mice. These findings suggest that the action of L. alata in treating malaria infections in a murine model is enhanced by prior exposure to the malaria parasite. Thus the requirements of using plants in treating malaria in endemic populations may differ for those used in western systems, where trials are carried out with non immune cohorts. Combining artemisinin derivatives and medicinal plants in malaria exposed populations may provide an alternative control measure in endemic regions and may justify the continued use of these plants by indigenous populations in treating malaria. PMID- 29190857 TI - Preparation, in vitro Characterization and Pharmacokinetic Study of Coenzyme Q10 Long-Circulating Liposomes. AB - Long-circulating liposomal delivery systems of encapsulated Coenzyme Q10 (CoQ10), a ubiquinone anti-cataract agent, were developed with different molar ratios of PEGylated lipids and/or cholesterol. The resulting samples were contrasted through observation of morphology, analysis of particle size and Zeta potential, and in vivo pharmacokinetics. A protamine aggregation method with high selectivity was developed to determine the encapsulation efficiency (EE), after which the liposome formulation was further optimized by applying a Box Behnken design (BBD) using EE as the evaluation index. The results showed that liposomes had a large, unilamellar structure, and that particle sizes of cholesterol containing liposomes increased along with the increase of cholesterol molar percentage, while the size of PEGylated vesicles decreased slightly as PEG-lipid contents increasing. The optimum formulation and optimal values of each influencing factor were quantitatively obtained, and the measured value was highly consistent with the predicted results. In vivo evaluation performed by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) demonstrated that liposomal encapsulation largely prolonged half-lives and improved bioavailability for vectors prepared with either lipid component, and the liposomes composed of both cholesterol and PEG-lipid possessed the best pharmacokinetic properties. The results suggest that incorporating high contents of cholesterol and PEG modification could be a potentially useful method for enhancing the length of circulation and the sustained release effect for liposome encapsulated chemicals.

AB - On August, the second edition of the Healthcare Book Fair took place, sponsored by the Facultad de Medicina of UNAM. Again, the Revista Medica del Instituto Mexicano del Seguro Social participated with a stand where we promoted it, talked about the different indexes where our journal is included, explained its objective and scope, and finally talked about its nature as an open access journal, which is aimed to the clinical staff of the different health institutions of our country. PMID- 29190860 TI - [Hemodynamic regime of asymptomatic heart disease patients studied by echocardiogram]. AB - BACKGROUND: Viewing heart failure as a clinical syndrome delays treatment and impairs prognosis, which leads to the question: Is it possible to make an early diagnosis based on echocardiography studies? METHODS: It was carried out a review of medical records of asymptomatic heart disease patients, with no treatment, who were studied by echocardiogram in order to measure cardiac output (CO) and total peripheral vascular resistance (TPVR), for which mean blood pressure was calculated. It is described the hemodynamic regime on the basis of the proportion of three integrated groups according to CO and TPVR. RESULTS: The hemodynamic regime in 200 heart disease patients was hypokinetic in 36%, hyperkinetic in 17% and eukinetic in 47%. CONCLUSIONS: Non-invasive hemodynamic study identified asymptomatic heart failure in one third of the cases. PMID- 29190859 TI - [Work accidents associated with the discouragement of SERUMS physicians to work in the primary care services of Lima, Peru]. AB - BACKGROUND: Employee retention is an important issue, because professionals are required in primary care services (PCS). The objective was to determine whether accidents were associated with the discouragement of physicians to work in PCS in Lima, Peru. METHODS: Analytical cross-sectional study of secondary data from a database generated from a survey of physicians who performed his Rural and Urban Health Care Service (Servicio Rural y Urbano-Marginal en Salud: SERUMS). We only included physicians who said at the beginning of their SERUMS that they could work in PCS in Lima. Those who completed their service and reported that they no longer wished to work in Lima were defined as change of intention to work in PCS. This was associated with having a work accident and was adjusted with other variables. RESULTS: Out of 124 physicians, 63% (78) were men. Median age was 26 years (interquartile range: 25-27 years). After they completed their SERUMS, 12% (15) said they changed their mind and that they wished to work in Lima. In the multivariate analysis, having had an accident diminished the frequency of changing their mind of working in the PCS (aPR: 0.28, 95% CI: 0.14-0.54, p < 0.001), adjusted for eight variables. CONCLUSIONS: A previous study found that work accidents decreased the frequency outside Lima, but our study states the opposite, probably because of the perception that a job in the capital would allow them to be closer to services; to be cared for in case of any emergency. PMID- 29190861 TI - [Prediction of acute kidney injury in critically ill patients treated with intermittent hemodialysis versus CRRT]. AB - BACKGROUND: Acute kidney injury (AKI) is common in critically ill patients and it is associated with poor outcome. Some patients require renal replacement therapy (RRT), and the most frequently used are intermittent hemodialysis (IHD) and continuous renal replacement therapies (CRRT). Current evidence is insufficient to conclude which modality is most appropriate to treat critically ill patients with AKI. METHODS: We reviewed the clinical records of critically ill patients with stage 3 AKI treated with RRT. We recorded demographic and clinical data and serum creatinine. We compared the evolution and prognosis of patients treated with IHD versus those treated with CRRT by Student's t test, chi squared, Kaplan Meier curves, and Cox regression. Logistic regression was performed to determine the association between RRT and mortality. RESULTS: We analyzed 221 patients; the mean age was 49.8 years, and 55.2% were men. Mortality was 36.7%. IHD was used in 73.8% and CRRT in 26.2% of cases. In the group treated with CRRT, the severity of disease was higher, the recovery of renal function less frequent, the need for long-term RRT less frequent, and mortality higher, compared with those treated with IHD. CRRTs had an odds ratio (OR) of 8.64 for mortality (p = 0.063). CONCLUSIONS: IHD is the RRT most frequently used. Mortality is higher in patients treated with CRRT. CRRTs are not an independent risk factor for death. PMID- 29190862 TI - [Comparison of mortality by femur fracture versus hip fracture in elderly patients in a period of five years]. AB - BACKGROUND: Fractures in the elderly population are an economic, social and medical challenge. Not much is known about fractures in this population, which makes difficult the selection of an appropriate treatment. Hip fractures (HF) increase the risk of death and morbidity. Patients with midshaft femur fracture (MFF) have less morbidity and risk of death. The objective was to compare HF and MFF's survival. METHODS: Observational analytic study. The Hospital General de Mexico database was used to gather patients aged 65 to 94 years with HF and MFF from 2010 to 2014. Patients had an heterogeneous follow-up and their cognitive status was not considered; we had a total of 146 patients. Follow-up was made through phone call. RESULTS: Kaplan-Meier estimate was used to assess survival. We compared survival depending on type of fracture and found no statistically significant difference (p = 0.97). On sub-analysis, we compared type of fracture on male gender (p = 0.21) and female gender (p = 0.316) and found no statistically significant difference on survival. This differs from what has been reported. It was used t test to evaluate survival in months, according to male (39.61 +/- 19.1) and female (36.58 +/- 23.19) gender; this showed a significant difference in both groups (p = 0.037). CONCLUSIONS: In the presence of fractures, we must consider gender when estimating survival on patients with hip or midshaft femur fracture. PMID- 29190863 TI - [Effect of exercise on the serum concentrations of leptin and adiponectin in adolescents with risk factors of developing diabetes]. AB - BACKGROUND: Type 2 diabetes mellitus (T2DM) is an increasing health issue. Physical activity (PA) in early stages is a preventive measure in the development of degenerative diseases. It has been documented the association between exercise and leptin and adiponectin concentrations. The objective was to evaluate the effect of a physical activity program (PAP) on serum leptin and adiponectin in teenagers with risk factors for developing T2DM. METHODS: Experimental longitudinal study. Teenagers (men and women), with T2DM risk factors, aged 14 to 16 years, participated in a PAP for three months, five days a week, 45 minutes each day. Before and after the program, all anthropometric variables, incluiding leptin and adiponectin, were evaluated. RESULTS: 22 adolescents participated in the PAP and they were compared with 22 adolescents from the control group (who did not participate in the PAP). There was a reduction in the serum concentration of leptin in the intervention group (baseline 23 +/- 13; after the PAP 14 +/- 8, p > 0.0001), compared with the control group (baseline 18 +/- 13, three months follow-up 20 +/- 14, p < 0.520). Also, the adiponectin concentration increased (baseline 10 +/- 3, after the PAP 13 +/- 4.0, p > 0.014), compared with the control group (baseline 11 +/- 3, 13 +/- 4.0 after the PAP p > 0.032). CONCLUSIONS: This study support the efficacy of an aerobic exercise intervention on metabolic markers of adolescents with risk factors for developing diabetes. PMID- 29190864 TI - [Application of BARS scale in children with ataxia in a child rehabilitation center in Chiapas, Mexico]. AB - BACKGROUND: Ataxias are an heterogeneous group of diseases with different etiologies. Scales are used to understand better its natural history and evaluate properly drug efficacy in clinical trials. SARA and ICARS scales have been the most studied and validated so far. BARS scale is based on a modified form of the ICARS scale and is valid, reliable and sufficiently fast for clinical purposes. METHODS: Cross-sectional, descriptive and correlational study. Kruskall-Wallis test was used. We administered BARS to children from 4 to 18 years of age, with ataxic syndrome, without cognitive impairment, in active status, from February, 2007 to September, 2014, at the CRIT (Centro de Rehabilitacion Infantil Teleton) from Chiapas, Mexico. RESULTS: 14 children were included. The main BARS score was 17.9/30; 4H syndrome with the worst score was 27.6/30; ataxia telangiectasia 15.6/30; ataxic cerebral palsy 12/30; and others 16.1/30. Kruskall-Wallis test did not show a significant statistically difference when comparing the etiology with BARS score (p = 0.068). CONCLUSIONS: BARS items were an easy way to assess ataxic clinic in children; worse condition was found in neurodegenerative ataxias and better results in ataxic cerebral palsy.

AB - BACKGROUND: Low-penetrance susceptibility genes such as 5,10 methylenetetrahydrofolate reductase gene (MTHFR) have been considered in the progression of breast cancer (BC). Cancer is a result of genetic, environmental and epigenetic interactions; therefore, these genes should be studied in environmental context, because the results can vary between populations and even within the same country. The objective was to analyze the allelic and genotypic frequencies of the MTHFR C667T SNP in Mexican Mestizo patients with BC and controls from Northeastern Mexico. METHODS: 243 patients and 118 healthy women were studied. The analysis of the polymorphism was performed with a DNA microarray. Once the frequency of the polymorphism was obtained, Hardy-Weinberg equilibrium test was carried out for the genotypes. Chi square test was used to compare the distribution of frequencies. RESULTS: The allele frequency in patients was: C = 0.5406; T = 0.4594 and in controls C = 0.5678, T = 0.4322. Genotype in BC patients was: C / C = 29.9%, C / T = 48.3% and T / T = 21.8. The distribution in controls was: C / C = 31.4%, C / T = 50.8%, T / T = 17.8% (chi squared 0.77, p = 0.6801). CONCLUSIONS: Northeastern Mexican women in this study showed no association between MTFHR C667T SNP and the risk of BC. It seems that the contribution of this polymorphism to BC in Mexico varies depending on various factors, both genetic and environmental. PMID- 29190866 TI - [Chronic kidney disease in Mexico and its relation with heavy metals]. AB - Chronic kidney disease (CKD) is a public health problem in Mexico, causing 25% of deaths related to diabetes mellitus (DM) and 28% related to hypertensive heart disease. In 2008 CKD reached the highest incidence of end-stage renal disease in the world. Diabetes mellitus is the main risk factor associated with CKD in Mexican population; however, heavy metals such as lead, arsenic, cadmium and mercury have been associated to nephropathies. In Mexico there are still high levels of these compounds in occupational and environmental settings; therefore, chronic exposures to these metals persist. In this review we approach to the main mechanisms of action of these metals in the body and its renal effects, as well as information about the sources of exposure to these chemical risks, the relationship between exposure to heavy metals and CKD, coupled with the economic and social consequences of this disease.

AB - The aim of this paper is to describe educational programs that reportedly teach how to break bad news in the emergency department. We also suggest some recommendations on how to communicate bad news based on the research of evidence available in the field. The examined evidence points toward six major components with which physicians should familiarize when communicating bad news: 1) doctor patient empathic communication, 2) establishing a proper space to give the news, 3) identifying characteristics of the person who receives the news, 4) essential aspects for communicating the news; 5) emotional support, and 6) medical and administrative aspects of the encounter. Finally, we point out several limitations in the studies in the field and future challenges identified in the communication of bad news in emergency room facilities.

It represents the main cause of vision loss in diabetes type I and II with a prevalence of 3-10% in diabetic patients of the Instituto Mexicano del Seguro Social (IMSS). Our aim is to elaborate treatment guidelines and provide recommendations for the use of intravitreal ranibizumab for diabetic medical edema at IMSS. Nine retina specialists and 10 ophthalmologists from IMSS high specialty medical units gathered to discuss the bibliographic evidence for the safety and efficacy of ranibizumab for this disease, in order to create consensus on its use in the institution. Intravitreal ranibizumab injection should be used on patients presenting diffuse or cystic diabetic macular edema who have strict metabolic control and visual acuity between 20/30 and 20/200 ETDRS, as well as structural features, such as inferior foveal limit of 280 MUm and ischemic areas no larger than 50% of the central foveal area. Treatment regime should consist of a loading charge of three monthly injections of ranibizumab 0.5 mg, followed by monthly follow-ups and treatment as needed according to anatomic and functional criteria. This consensus decision-making process on the criteria to treat and re treat patients with this drug will result in better health outcomes than those currently observed among patients with diabetic macular edema at IMSS.

AB - Librarian and information services focused on supporting research, teaching, and health care are vital for the generation of new knowledge and its application in health care, both by staff and students, helps to improve the quality of medical care. Therefore, in this article we expose an historical and social tour of 50 years of the Instituto Mexicano del Seguro Social's library services in Puebla. From 1964 to 2014 occurred many events in the development of these services in our area, from the creation of a small space in the basement, to the implementation of spaces created deliberately to provide dignified service to all users, which is why this historical sketch is here as an acknowledgement to the first librarians who contributed to the training of specialists in Mexico. PMID- 29190872 TI - [Level of teaching competence at the Undergraduate Medical Internship of UNAM's Faculty of Medicine]. AB - BACKGROUND: There is no systematic evaluation of teaching performance in the clinical area at UNAM Faculty of Medicine. The study purpose is to assess the teaching competence level in the Undergraduate Medical Internship (UMI). METHODS: The paper describes the process of psychometric validity for the instrument designed to evaluate teaching competence in the UMI. This instrument was constructed from two previously developed instruments. The final version with 54 items in a Likert scale was studied with exploratory factorial analysis. Four dimensions were obtained: Solution of clinical problems, Psychopedagogy, Mentoring, and Evaluation. The instrument had a reliability of 0.994, with an explained variance of 77.75%. RESULTS: To evaluate the teaching competence level, we administered 844 questionnaires to a sample of students with a response rate of 89%. We obtained an overall global score of 89.4 +/- 9.6 (mean +/- SD). The dimension Solution of clinical problems was the one with a greater value, in contrast with the dimension of Evaluation, which had a lower score. CONCLUSION: The teachers of the UMI are considered educators with high level of teaching competence, according to the perceptions of the undergraduate internal doctors. The evaluation of teaching competence level is very important for institutions that look for the continuous professional development of its faculty. PMID- 29190873 TI - [Segmental portal hypertension with splenic vein thrombosis caused by pancreatitis]. AB - BACKGROUND: Splenic vein thrombosis is a complication of pancreatic carcinoma, pancreatitis or pancreatic pseudocyst. It may lead to segmental portal hypertension and bleeding from gastric varices. CLINICAL CASE: A 31 year-old man was diagnosed with pancreatitis of two weeks of evolution and was referred to our hospital in 2013. He had a history of alcohol consumption. Physical examination showed no stigmata of liver cirrhosis. Laboratory analyses revealed hemoglobin 9.5 g/dL, and leukocytes and platelets were normal. Liver function tests were normal as well. Abdominal CT showed a pseudocyst, which was drained by percutaneous puncture. By pseudocyst recurrence, drainage and necrosectomy by retroperitoneal laparascopy were performed. The patient presented hyperglycemia during his treatment in hospital. He was discharged, but he returned to emergency room because of gastrointestinal bleeding without hemodynamic instability. Gastroscopy showed bleeding gastric varices. The colonoscopy showed normal results. Liver biopsy was also normal. Abdominal CT angiography revealed blockage of the splenic vein. Patient underwent splenectomy and was discharged. CONCLUSION: This case is rare due to the high frequency of portal hypertension and cirrhosis. The isolated gastric varices with normal liver function are a sign of splenic thrombosis. The definitive treatment is splenectomy. PMID- 29190874 TI - [Subaortic membrane in adults. A brief review of literature apropos of one case]. AB - A 54-year-old man, ex smoker with high blood pressure and a history of possible Wolff-Parkinson-White syndrome was admitted for presenting an episode suggestive of acute coronary syndrome with immediate syncope and left bundle branch block, while performing physical activity. Angioplasty and a drug-eluting stent were performed in the left circumflex artery. Subsequently, Doppler echocardiography disclosed an image suggestive of a subaortic membrane. Given these findings, the patient underwent a 3D transesophageal echocardiogram and a magnetic resonance study, which confirmed the diagnosis of a subaortic membrane. In turn, in the Holter monitoring a paroxysmal pattern of Wolff-ParkinsonWhite was observed. The patient presented three possible causes of syncope. A stress echocardiogram elicited a gradient of 126 mm Hg, which could be possibly related to the syncopal episode that the patient suffered. PMID- 29190875 TI - [IgG4-related disease: a case report]. AB - IgG4-related disease is an inflammatory condition characterized by high levels of IgG4. It affects salivary and lacrimal glands, pancreas, lymph nodes, lungs or kidney. The diagnosis is based on identifying a histological pattern with a dense lymphocyte and plasmacyte infiltration, focal fibrosis or phlebitis, finding more than 10 IgG4 positive cells per high power field and/or IgG4/IgG ratio in plasma higher than 40%. We present a patient with Mikulicz's disease who meets histological findings required for the diagnosis of IgG4 related disease.

PMID- 29190877 TI - Measurement of retropubic tissue thickness using intrapartum transperineal ultrasound to assess cephalopelvic disproportion. AB - PURPOSE: First, to describe a new method of assessing cephalopelvic disproportion by measuring the retropubic tissue thickness (RTT), and second, to determine whether RTT was associated with an eventual delivery by cesarean section. METHODS: Three-dimensional transperineal ultrasound scans were performed on 129 laboring nulliparous women to obtain 3-dimensional volume datasets for assessing RTT. RTT was measured off-line by three operators (A, B, and C) as the shortest distance between the capsule of the pubic symphysis and the outer border of the fetal skull. The intraoperator repeatability of operator A and the interoperator reproducibility among A, B, and C were determined. The RTT in women who were delivered by cesarean section due to failure to progress was compared to that of women who had a vaginal delivery. RESULTS: The intraoperator repeatability for RTT was 1.2 mm. The overall RTT interoperator interclass correlation was 0.97 (0.95-0.98). The RTT in women who had a spontaneous, instrumental, or cesarean delivery was 1.16+/-0.32 cm, 1.12+/-0.25 cm, and 0.94+/-0.25 cm, respectively. Women who were delivered by cesarean section had a significantly smaller RTT than women who had a spontaneous delivery (P=0.008). There was no statistically significant difference in RTT between patients who had a normal vaginal delivery and patients who had an instrumental delivery (P=0.990), or between those who had an instrumental delivery and those who had a cesarean delivery after the Bonferroni correction (P=0.120). CONCLUSION: RTT can be measured with satisfactory intraoperator repeatability and interoperator reproducibility. RTT was significantly smaller in women who eventually had a cesarean delivery than in those who had a vaginal delivery.

AB - Six Transmembrane Protein of Prostate 2 (STAMP2) has been implicated in both prostate cancer (PCa) and metabolic disease. STAMP2 has unique anti-inflammatory and pro-metabolic properties in mouse adipose tissue, but there is limited information on its role in human metabolic tissues. Using human adipose-derived stem cells (ASCs), we report that STAMP2 expression is dramatically upregulated during adipogenesis. shRNA-mediated STAMP2 knockdown in ASCs significantly suppresses adipogenesis and interferes with optimal expression of adipogenic genes and adipocyte metabolic function. Furthermore, ASC-derived adipocyte mediated stimulation of prostate tumor growth in nude mice is significantly reduced upon STAMP2 knockdown in ASC adipocytes. These results suggest that STAMP2 is crucial for normal ASC conversion into adipocytes and their metabolic function, as well as their ability to facilitate PCa growth in vivo. PMID- 29190879 TI - Longevity of protective immune responses induced by a split influenza A (H7N9) vaccine mixed with MF59 adjuvant in BALB/c mice. AB - The influenza virus is a serious threat to public health worldwide. A novel avian influenza A (H7N9) virus with a mortality rate of approximately 30% has been identified as an unusually dangerous virus for humans by the World Health Organization. Pathogenic H7N9 continue to represent a public health concern, and several candidate vaccines are currently in development. We generated candidate H7N9 vaccine strains using reverse genetics, consisting of hemagglutinin and neuraminidase genes derived from a human H7N9 virus and the remaining genes from the PR8 (A/PuertoRico/8/34 (H1N1)) virus. This H7N9 vaccine exhibited superior efficacy when combined with MF59 compared to other adjuvants. Immunized BALB/c mice were followed to determine the duration of the protective immune response. Antibody levels decreased to between one-half and one-eighth of the peak values four months after the final dose of the vaccine. Previously vaccinated mice received an A/Zhejiang/DTID-ZJU01/2013 H7N9 challenge six months post vaccination, and all remained protected. We also verified that MF59 enhanced the HI, MN, and IgG antibody titers to influenza antigens. The humoral immune response and Th2 cytokine production following influenza challenge was potently induced in the animals that received the split vaccine. Therefore, the split H7N9 influenza vaccine with the MF59 adjuvant could effectively induce antibody production and protect mice from H7N9 virus challenge even after six months. PMID- 29190880 TI - Enhancement of the anti-tumor activity of FGFR1 inhibition in squamous cell lung cancer by targeting downstream signaling involved in glucose metabolism. AB - Fibroblast Growth Factor Receptor (FGFR) signaling is a complex pathway which controls several processes, including cell proliferation, survival, migration, and metabolism. FGFR1 signaling is frequently deregulated via amplification/over expression in NSCLC of squamous histotype (SQCLC), however its inhibition has not been successfully translated in clinical setting. We determined whether targeting downstream signaling implicated in FGFR1 effects on glucose metabolism potentiates the anti-tumor activity of FGFR1 inhibition in SQCLC. In FGFR1 amplified/over-expressing SQCLC cell lines, FGF2-mediated stimulation of FGFR1 under serum-deprivation activated both MAPK and AKT/mTOR pathways and increased glucose uptake, glycolysis, and lactate production, through AKT/mTOR-dependent HIF-1alpha accumulation and up-regulation of GLUT-1 glucose transporter. These effects were hindered by PD173074 and NVP-BGJ398, selective FGFR inhibitors, as well as by dovitinib, a multi-kinase inhibitor. Glucose metabolism was hampered by the FGFR inhibitors also under hypoxic conditions, with consequent inhibition of cell proliferation and viability. In presence of serum, glucose metabolism was impaired only in cell models in which FGFR1 inhibition was associated with AKT/mTOR down-regulation. When the activation of the AKT/mTOR pathway persisted despite FGFR1 down-regulation, the efficacy of NVP-BGJ398 could be significantly improved by the combination with NVP-BEZ235 or other inhibitors of this signaling cascade, both in vitro and in xenotransplanted nude mice. Collectively our results indicate that inhibition of FGFR1 signaling impacts on cancer cell growth also by affecting glucose energy metabolism. In addition, this study strongly suggests that the therapeutic efficacy of FGFR1 targeting molecules in SQCLC may be implemented by combined treatments tackling on glucose metabolism. PMID- 29190881 TI - Toll-like receptor expression in human non-small cell lung carcinoma: potential prognostic indicators of disease. AB - Introduction: Lung cancer remains the highest cause of cancer mortality worldwide. Toll-like receptors (TLR) are innate immune receptors that have both pro- and anti-tumorigenic properties. Based on findings from epidemiological studies and in rodents, we hypothesized that elevated TLR expression would be a positive prognostic indicator of disease in non-small cell lung carcinoma patients. Results: Higher mRNA expression of TLR1-3 and 5-8 were significantly associated with increased overall survival (OS) when analyzed individually or as a group in both non-small cell lung carcinoma (NSCLC) patients and in the adenocarcinoma (ADC) subtype. Significant co-expression of many TLR combinations in ADC patients were also observed via RNA sequencing. Immunostaining demonstrated TLR4 and 8 significantly correlated in tumor tissue, similar to RNA. Methods: We used kmplot.com to perform a meta-analysis on mRNA expression of TLR1 10 to determine any significant associations with OS in NSCLC and the ADC subtype. cBioportal was also used simultaneously to assess co-expression in TLR1 10 in ADC patients via RNA sequencing and to identify any molecular alterations. Lastly, immunostaining for a subset of TLRs was conducted on ADC patients. Conclusions: Expression of innate immune receptors TLR1-10 is associated with improved survival outcomes in NSCLC. Thus, further evaluation of their predictive capacity and therapeutic utility is warranted. PMID- 29190882 TI - Functional polymorphisms in pre-miR146a and pre-miR499 are associated with systemic lupus erythematosus but not with rheumatoid arthritis or Graves' disease in Mexican patients. AB - Recently, different microRNA (miRNA) gene polymorphisms have been evaluated in patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and Graves' disease (GD). In the present study, we examined three single-nucleotide polymorphisms (SNPs) located in the pre-miR-146a (rs2910164G/C), pre-miR-196a-2 (rs11614913C/T), and pre-miR-499 (rs3746444A/G) genes. Our study population included 900 Mexican patients with RA, SLE, or GD, as well as 486 healthy control individuals with no family history of inflammatory or autoimmune diseases. Genotyping was performed using TaqMan probes and a 5' exonuclease assay. None of the investigated SNPs were associated with RA or GD susceptibility under any genetic model (co-dominant, recessive, or dominant). Genotype and allele frequencies of the miR-196a-2 rs11614913C/T polymorphism were similar between SLE cases and controls. In contrast, the miR-146a rs2910164G/C and miR-499 rs3746444A/G polymorphisms were associated with SLE susceptibility. These SNPs were not associated with lupus nephritis (LN). Our results suggest that polymorphisms in miR-146a, miR-196a-2, and miR-499 are not associated with RA or GD susceptibility. This is the first report documenting that the miR-146a rs2910164G/C and miR-499 rs3746444 polymorphisms are associated with SLE susceptibility but not with LN. PMID- 29190883 TI - Ghrelin protects against nucleus pulposus degeneration through inhibition of NF kappaB signaling pathway and activation of Akt signaling pathway. AB - The objective of the present study was to examine the potential role of ghrelin in degeneration of nucleus pulposus (NP). Lower expression levels of ghrelin were found in human NP cells stimulated with interleukin-1beta (IL-1beta). Moreover, exogenous ghrelin suppressed IL-1beta induced degeneration and inflammation associated biomarkers in human NP cells, including matrix metalloproteinase-13, a disintegrin and metalloproteinase with thrombospondin motifs-5, tumor necrosis factor-alpha and iNOS, which was possibly mediated by antagonization of NF-kappaB signaling. Moreover, ghrelin enhanced production of critical extracellular matrix of NP cells, including collagen 2, aggrecan, and Sox-9 in NP cells. Ghrelin also promoted NP tissue regeneration in a rabbit IVD degeneration model, which seems to be associated with growth hormone secretagogue receptor. Additionally, the protective role of ghrelin in anabolism potentially relies on activation of Akt signaling pathway. Taken together, ghrelin may represent a molecular target for prevention and treatment of intervertebral disc degeneration. PMID- 29190884 TI - The autophagy marker LC3 strongly predicts immediate mortality after surgical resection for hepatocellular carcinoma. AB - The remnant liver's ability to regenerate may affect post-hepatectomy immediate mortality. The promotion of autophagy post-hepatectomy could enhance liver regeneration and reduce mortality. This study aimed to identify predictive factors of immediate mortality after surgical resection for hepatocellular carcinoma (HCC). A total of 535 consecutive HCC patients who had undergone their first surgical resection in Taiwan were enrolled between 2010 and 2014. Clinicopathological data and immediate mortality, defined as all cause-mortality within three months after surgery, were analyzed. The expression of autophagy proteins (LC3, Beclin-1, and p62) in adjacent non-tumor tissues was scored by immunohistochemical staining. Approximately 5% of patients had immediate mortality after surgery. The absence of LC3, hypoalbuminemia (<3.5 g/dl), high alanine aminotransferase, and major liver surgery were significantly associated with immediate mortality in univariate analyses. Multivariate logistic regression demonstrated that absence of LC3 (hazard ratio/95% confidence interval: 40.8/5.14 325) and hypoalbuminemia (2.88/1.11-7.52) were significantly associated with immediate mortality. The 3-month cumulative incidence of mortality was 12.1%, 13.0%, 21.4% and 0.4%, respectively, among patients with absence of LC3 expression, hypoalbuminemia, both, or neither of the two. In conclusion, the absence of LC3 expression in adjacent non-tumor tissues and hypoalbuminemia were strongly predictive of immediate mortality after resection for HCC. PMID- 29190886 TI - Metformin activates type I interferon signaling against HCV via activation of adenosine monophosphate-activated protein kinase. AB - Activation of the type I interferon (IFN) signaling pathway is essential for the eradication of hepatitis C virus (HCV). Metformin can activate adenosine monophosphate-activated protein kinase (AMPK) to reduce insulin resistance. Cross talks between AMPK and IFN signaling remain unclear. To understand the influence of metformin on the type I IFN signaling pathway and HCV infection, the full length HCV replicon OR6 cells and the infectious HCV clones JFH1 were used to assess the anti-HCV effect of the insulin sensitizers, metformin and pioglitazone. Immunofluorescence staining and the immunoblotting of HCV viral protein demonstrated that metformin, but not pioglitazone, inhibited HCV replication in OR-6 and JFH-1-infected Huh 7.5.1 cells. Immunoblotting data showed that metformin activated the phosphorylation of STAT-1 and STAT-2 in OR-6 and JFH-1 infected Huh 7.5.1 cells. Metformin enhanced the phosphorylation of AMPK, and the metformin-activated IFN signaling was down-regulated by AMPK inhibitor. After treatment of AMPK inhibitor, the level of HCV core protein decreased by metformin can be rescued. In conclusion, metformin activates type I interferon signaling and inhibits the replication of HCV via activation of AMPK. PMID- 29190885 TI - The IDO inhibitor 1-methyl tryptophan activates the aryl hydrocarbon receptor response in mesenchymal stromal cells. AB - The catabolism of tryptophan (Trp) by indoleamine 2,3-dioxygenase (IDO) is a key step in tolerance effected by a variety of cell types, including mesenchymal stromal cells (MSCs). Trp catabolism generates molecules known as kynurenines, whose tolerance mechanisms involve activation of the Aryl Hydrocarbon Receptor (AHR). A synthetic analog of Trp, 1-methyl tryptophan (1MT), is a selective inhibitor of IDO enzymatic activity being utilized in cancer immunotherapy trials. We hypothesized 1MT might activate AHR independently of its effects on IDO. We demonstrate MSCs express AHR protein, and that in vitro treatment with 1MT causes AHR nucleotranslocation. Upon analyzing mRNA, we observed transcriptional upregulation of cytochrome p450 1a1 and 1b1 by 1MT racemic mixture (R-MT), consistent with AHR-activation. RNA-sequencing identified Nrf2, MAPK12 and IL-1a as downstream targets of 1MT. We demonstrate 1a1 and 1b1 activation by 1MT in IDO+ MSC following interferon-gamma (IFN-gamma) activation, suggesting AHR signaling is uncoupled from IDO catalytic function. Such a mechanism of action for 1MT may extend its usage to a wider range of patients, irrespective of tumor IDO expression. These observations support a novel paradigm by which AHR-activating compounds like 1MT can be used in cancer immunotherapy to stimulate a pro-inflammatory response. PMID- 29190887 TI - MiR-205 as a promising biomarker in the diagnosis and prognosis of lung cancer. AB - MicroRNA-205 (miR-205) was revealed as a novel diagnostic and prognostic biomarker for lung cancer, but the results in the published papers were inconsistent. This meta-analysis aimed to investigate the diagnostic and prognostic roles of miR-205 in patients with lung cancer. Totally, 16 eligible articles were included, among which 10 articles investigated the diagnostic value of miR-205, 5 articles examined its prognostic values, and 1 article studied both diagnostic and prognostic values. For the diagnostic meta-analysis, the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and the overall area under the curve of miR-205 for patients with lung cancer were 0.88 (95% CI = 0.78 - 0.94), 0.78 (95% CI = 0.66 - 0.86), 4.00 (95% CI = 2.47 - 6.49), 0.16 (95% CI = 0.08 - 0.30), 25.86 (95% CI = 9.29 - 71.95), and 0.90 (95% CI = 0.87 - 0.92), respectively, indicating that miR 205 is a useful biomarker for diagnostic of lung cancer. The subgroup analysis further demonstrated that miR-205 had an excellent overall accuracy for detection with tissue samples compare with blood samples. For the prognostic meta-analysis, the pooled outcome of the disease-free survival and recurrence-free survival analyses revealed that increased miR-205 levels had a protective role in the prognosis of patients with lung cancer (pooled HR = 0.86, 95% CI: 0.78-0.96, z = 2.83, P = 0.005). In conclusion, miR-205 may be a promising biomarker for detection, predicting the recurrence of patients with lung cancer. PMID- 29190888 TI - Genomic profiles of a hepatoblastoma from a patient with Beckwith-Wiedemann syndrome with uniparental disomy on chromosome 11p15 and germline mutation of APC and PALB2. AB - Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth disorder mainly associated with altered genomic imprinting at chromosome 11p15.5. Children with BWS, especially uniparental disomy (UPD) at 11p15.5, are at increased risk of embryonal tumors including hepatoblastoma. Although genetic alterations of sporadic hepatoblastomas have been identified, integrated germline and somatic alterations of BWS-related hepatoblastoma have not been reported. For this, we performed whole-exome sequencing and genome-wide loss of heterozygosity/copy number analyses using a single nucleotide polymorphism (SNP) array for a hepatoblastoma in a BWS infant with paternal UPD at chromosome 11p15.5. We found germline 11p15.5 UPD as well as germline mutations of APC and PALB2 in the patient. At the somatic level, we found a CTNNB1 hotspot mutation and chromosome 1q gain in the tumor. The development of hepatoblastoma in this case might be explained by predisposition of the germline events (11p15.5 UPD, mutations of APC and PALB2) and later by somatic events with CTNNB1 somatic mutation and 1q gain. To our knowledge, this is the first report of germline and somatic genomic alteration profiles in hepatoblastoma arising from BWS. Clinically, our results provide a rationale for performing a more strict and intense protocol for hepatoblastoma surveillance in a high-risk BWS infant, such as the UPD-carrying case, for early detection and treatment. PMID- 29190889 TI - Aberrant brain grey matter volume patterns differ among Chinese Han drug-naive depression patients with acute and chronic stress. AB - Chronic or acute stress can induce structural changes and brain alterations associated with the neural mechanisms of depression. Aimed to investigate the GMV alterations in the drug-naive depression patients with chronic and acute stress experience,we enrolled fifty depression patients with acute stress experience, fifty five depression patients with chronic stress experience and forty seven healthy controls(HC) to participant in the present study. We used voxel-based morphometry to analyze the brain grey matter volume (GMV) alterations. Compared with the HC, the patients with acute stress and those with chronic stress exhibited a distinct GMV impairment pattern. Widespread, decreased GMV was detected in most of the cerebral cortex in all the depression patients. Importantly, the greatest finding in our study is that the decreased GMV in the depression patients with chronic stress was more widespread than that in the patients with acute stress. All brain regions with decreased GMV participated in the regulation of emotions, memory, and executive function processing, which is consistent with previous findings. There was no significant difference between the major depression disorder patients with acute stressful life events and those with chronic stressful life events, and this finding largely weakens the support of our current conclusion. Thus, we cannot confirm this postulation. However, our findings probably indicate that GMV may be more sensitive to major depression disorder patients when compared to healthy controls, it did not sensitive when in the comparison of patient's group. Overall, our findings provide important information for the use of appropriate treatment methods to address acute stress and alleviate chronic stress in patients with depression, and such treatments can delay the deterioration of the affected brain regions and improve remission rates. More importantly, all the inexplicable findings in the present study encourage us to conduct a follow-up study to describe the developmental trajectory of the pathological brain features of depression patients and explore therapeutic targets for future personalized treatment. PMID- 29190890 TI - Administration of alpha-ketoglutarate improves epithelial restitution under stress injury in early-weaning piglets. AB - Alpha-ketoglutarate (AKG) is an important cellular metabolite that participates in energy production and amino acid metabolism. However, the protective effects and mechanism of AKG on mucosal lesions have not been well understood. This study was conducted to investigate the effects of dietary AKG supplementation on epithelial restitution in early-weaning piglets under Escherichia coli lipopolysaccharide (LPS) induction. A total of 32 weaned piglets were used in a 2 * 2 factorial design; the major factors were dietary treatment (basal diet or AKG diet) and inflammatory challenge (LPS or saline). The results showed that AKG supplementation improved the growth performance and intestinal morphology in the LPS-induced early-weaning piglets. Compared with the basal diet, the AKG diet remarkably decreased the concentration and mRNA expression of intestinal inflammatory cytokines (IL-1beta, IL-6, and IL-12) in the LPS-induced piglets. Moreover, AKG administration upregulated the mRNA expression of nutrient-sensing transporters (GLUT-2, SGLT-1, PEPT-1, I-FABP2) in the small intestine of both saline- and LPS-treated piglets, and improved the distribution and expression of tight-junction genes andproteins (ZO-1, Occludin, Claudins, E-cadherin). Collectively, our findings indicate that AKG has the potential to alleviate intestinal inflammatory response and improve epithelial restitution and nutrient sensing ability under stress injury in early-weaning piglets, and it also provides an experimental basis for enteral use of AKG in swine production and clinical application to prevent intestinal epithelial damage. PMID- 29190891 TI - High bone marrow ID2 expression predicts poor chemotherapy response and prognosis in acute myeloid leukemia. AB - Dysregulation of ID proteins is a frequent event in various human cancers and has a direct role in cancer initiation, maintenance, progression and drug resistance. Our previous study has revealed ID1 expression and its prognostic value in acute myeloid leukemia (AML). Herein, we further reported ID2 expression and its clinical significance in AML. Real-time quantitative PCR was performed to detect ID2 transcript level in bone marrow mononuclear cells of 145 de novo AML patients. ID2 expression was significantly up-regulated in AML patients compared with controls. ID2 overexpression occurred with the highest frequency in poor karyotype (10/17, 59%), lower in intermediate karyotype (35/83, 42%), and the lowest in favorable karyotype (7/40, 18%). Moreover, high ID2 expression correlated with lower complete remission (CR) rate, shorter overall survival, and acted as an independent prognostic biomarker in whole-cohort AML and non-M3-AML patients. Importantly, the prognostic value of ID2 expression in AML was validated by The Cancer Genome Atlas (TCGA) data. In the follow-up of patients, ID2 expression at CR phase was decreased than at the time of diagnosis, and was increased again at the time of relapse. These findings demonstrated that bone marrow ID2 overexpression was a frequent event in AML patients, and predicts poor chemotherapy response and prognosis. PMID- 29190892 TI - LncRNA H19 is a major mediator of doxorubicin chemoresistance in breast cancer cells through a cullin4A-MDR1 pathway. AB - Development of chemoresistance is a persistent problem during cancer treatment. Long non-coding RNAs (LncRNAs) are currently emerging as an integral functional component of the human genome and as critical regulators of cancer development and progression. In the present study, we investigated the role and molecular mechanism of H19 lncRNA in chemoresistance development by using doxorubicin (Dox) resistance in breast cancer cells as a model system. H19 lncRNA expression was significantly increased in anthracycline-treated and Dox-resistant MCF-7 breast cancer cells. This H19 overexpression was contributed to cancer cell resistance to anthracyclines and paclitaxel as knockdown of H19 lncRNA by a specific H19 shRNA in Dox-resistant cells significantly improved the cell sensitivity to anthracyclines and paclitaxel. Furthermore, gene expression profiling analysis revealed that a total of 192 genes were associated with H19-mediated Dox resistance. These genes were enriched in multiple KEGG pathways that are related to chemoresistance. Using genetic and pharmacological approaches, we demonstrated that MDR1 and MRP4 were major effectors of H19-regulated Dox resistance in breast cancer cells as MDR1 and MRP4 expression was markedly elevated in Dox-resistant cells while dramatically reduced when H19 was knocked down. Moreover, we found that CUL4A, an ubiquitin ligase component, was a critical factor bridging H19 lncRNA to MDR1 expression, and a high tumor CUL4A expression was associated with low survival in breast cancer patients treated with chemotherapy. These data suggest that H19 lncRNA plays a leading role in breast cancer chemoresistance, mediated mainly through a H19-CUL4A-ABCB1/MDR1 pathway. PMID- 29190893 TI - Effect of PGE2-EPs pathway on primary cultured rat neuron injury caused by aluminum. AB - To observe the characteristic changes of PGE2-EPs pathway and divergent functions of PGE2 receptor subtypes on neuronal injury. The primary cultured rat hippocampus neuron injury model was established via aluminum maltolate (100 MUM). The aluminum-overload neurons were treated with the agonists of EP1 (17-phenyl trinor Prostaglandin E2 ethyl amide), EP2 (Butaprost), EP3 (Sulprostone) and EP4 (CAY10598) and antagonists of EP1 (SC-19220), EP2 (AH6809) and EP4 (L-161982) at different concentrations, respectively. The neuronal viability, lactate dehydrogenase leakage rate and PGE2 content were detected by MTT assay, lactate dehydrogenase assay kit and enzyme-linked immunosorbent assay, respectively. The mRNA and protein expressions of mPGES-1 and EPs were determined by RT-PCR and western blot, respectively. The pathomorphology was identified by hematoxylin eosin staining. In the model group, neuronal viability significantly decreased, while lactate dehydrogenase leakage rate and PGE2 content increased. The mPGES-1, EP1, EP2 and EP4 mRNA expression, and the mPGES-1, EP1 and EP2 protein expression increased, while EP3 level decreased. EP3 agonist exerted protective function in neuronal viability and lactate dehydrogenase leakage rate, while EP1 agonist, EP2 and EP4 antagonist exerted an opposite effect. In conclusion, aluminum-overload caused an imbalance of PGE2-EP1-4 pathway and activation of EP receptor may provide a viable therapeutic target in neuronal injury. PMID- 29190894 TI - MicroRNA-212/ABCG2-axis contributes to development of imatinib-resistance in leukemic cells. AB - BCR-ABL-independent resistance against tyrosine kinase inhibitor is an emerging problem in therapy of chronic myeloid leukemia. Such drug resistance can be linked to dysregulation of ATP-binding cassette (ABC)-transporters leading to increased tyrosine kinase inhibitor efflux, potentially caused by changes in microRNA expression or DNA-methylation. In an in vitro-imatinib-resistance model using K-562 cells, microRNA-212 was found to be dysregulated and inversely correlated to ABC-transporter ABCG2 expression, targeting its 3'-UTR. However, the functional impact on drug sensitivity remained unknown. Therefore, we performed transfection experiments using microRNA-mimics and -inhibitors and investigated their effect on imatinib-susceptibility in sensitive and resistant leukemic cell lines. Under imatinib-treatment, miR-212 inhibition led to enhanced cell viability (p = 0.01), reduced apoptosis (p = 0.01) and cytotoxicity (p = 0.03). These effects were limited to treatment-naive cells and were not observed in cells, which were resistant to various imatinib-concentrations (0.1 MUM to 2 MUM). Further analysis in treatment-naive cells revealed that miR-212 inhibition resulted in ABCG2 upregulation and increased ABCG2-dependent efflux. Furthermore, we observed miR-212 promoter hypermethylation in 0.5 and 2 MUM IM-resistant sublines, whereas ABCG2 methylation status was not altered. Taken together, the miR-212/ABCG2-axis influences imatinib-susceptibility contributing to development of imatinib-resistance. Our data reveal new insights into mechanisms initiating imatinib-resistance in leukemic cells. PMID- 29190895 TI - Silibinin suppresses bladder cancer through down-regulation of actin cytoskeleton and PI3K/Akt signaling pathways. AB - Silibinin is the major active constituent of silymarin, an extract of milk thistle seeds. Silibinin has been shown to have significant anti-cancer effects in a variety of malignancies. However, the molecular mechanisms of silibinin action in bladder cancer have not been studied extensively. In the present study, we found that silibinin (10 MUM) significantly suppressed proliferation, migration, invasion and induced apoptosis of T24 and UM-UC-3 human bladder cancer cells. Silibinin down-regulated the actin cytoskeleton and phosphatidylinositide 3-kinase (PI3K)/Akt signaling pathways in these cancer cell lines. These pathways were found to crosstalk through RAS cascades. We found that silibinin suppressed levels of trimethylated histone H3 lysine 4 and acetylated H3 at the KRAS promoter. Furthermore, silibinin targets long non-coding RNA: HOTAIR and ZFAS1, which are known to play roles as oncogenic factors in various cancers. This study shows that silibinin exerts anti-cancer effects through down-regulation of actin cytoskeleton and PI3K/Akt pathways and thus suppresses bladder cancer growth and progression. PMID- 29190897 TI - Biomarkers identified for prostate cancer patients through genome-scale screening. AB - Prostate cancer is a threat to men and usually occurs in aged males. Though prostate specific antigen level and Gleason score are utilized for evaluation of the prostate cancer in clinic, the biomarkers for this malignancy have not been widely recognized. Furthermore, the outcome varies across individuals receiving comparable treatment regimens and the underlying mechanism is still unclear. We supposed that genetic feature may be responsible for, at least in part, this process and conducted a two-cohort study to compare the genetic difference in tumorous and normal tissues of prostate cancer patients. The Gene Expression Omnibus dataset were used and a total of 41 genes were found significantly differently expressed in tumor tissues as compared with normal prostate tissues. Four genes (SPOCK3, SPON1, PTN and TGFB3) were selected for further evaluation after Gene Ontology analysis, Kyoto Encyclopedia of Genes and Genomes pathway analysis and clinical association analysis. MIR1908 was also found decreased expression level in prostate cancer whose target genes were found expressing in both prostate tumor and normal tissues. These results indicated that these potential biomarkers deserve attention in prostate cancer patients and the underlying mechanism should be further investigated. PMID- 29190896 TI - Cofilin 1 promotes bladder cancer and is regulated by TCF7L2. AB - Earlier reports demonstrated that Cofilin expression is increased in bladder cancer samples, though its function remains unknown. Here, we found that Cofilin 1 expression was higher in bladder cancer tissues than in paracancerous tissues. Overexpression of Cofilin 1 promoted, while Cofilin 1 knockdown inhibited, proliferation, migration, and invasion in the T24 and RT4 bladder cancer cell lines. In addition, Cofilin 1 overexpression increased, while Cofilin 1 knockdown decreased, bladder tumor volumes in mouse xenograft experiments. Transcription factor 7-like 2 (TCF7L2) targeted the promoter of the Cofilin 1 gene, and TCF7L2 knockdown or mutations in the Cofilin 1 promoter dramatically decreased Cofilin 1 transcription. TCF7L2 promoted cell proliferation and migration and increased Cofilin 1 protein levels in RT4 and T24 cells. Thus, TCF7L2 contributed to Cofilin 1-induced promotion of bladder cancer development by binding to the Cofilin 1 promoter and increasing its expression. PMID- 29190898 TI - Trimedazidine alleviates pulmonary artery banding-induced acute right heart dysfunction and activates PRAS40 in rats. AB - The molecular mechanism underlying acute right heart failure (RHF) is poorly understood. We used pulmonary artery banding (PAB) to induce acute RHF characterized by a rapid rise of right ventricular pressure, and then a decrease in right ventricular pressure along with a decrease in blood pressure right after banding. We found higher brain natriuretic peptide (BNP) and beta-myosin heavy chain (betaMHC) levels and lower alpha-myosin heavy chain (alphaMHC) levels in RHF rats than sham-operated rats. Hemodynamic indexes in rats with acute RHF were slightly improved by trimedazidine TMZ, a key inhibitor of fatty acid (FA) oxidation. TMZ also reversed downregulation of peroxisome proliferator-activated receptor gamma coactivator 1-beta (PGC-1beta) and peroxisome proliferator activated receptor alpha (PPARalpha) by PAB and up-regulates peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1alpha), peroxisome proliferator-activated receptor delta (PPARdelta) and pyruvate dehydrogenase kinase isoform 4 (PDK4). In addition, TMZ reversed upregulation of phosphorylated Akt by PAB and increased phosphorylated proline-rich Akt-substrate 40 (PRAS40). Autophagy and apoptosis were not modified by PAB or TMZ. An acute RHF model was established in rats through 70% constriction of the pulmonary artery. TMZ treatment alleviated PAB-induced acute RHF by activating PRAS40 and upregulatingPGC-1alpha, PGC-1beta, PPARalpha, PPARdelta, and PDK4. PMID- 29190899 TI - Targeting myocyte-specific enhancer factor 2D contributes to the suppression of cardiac hypertrophic growth by miR-92b-3p in mice. AB - The role of microRNA-92b-3p (miR-92b-3p) in cardiac hypertrophy was not well illustrated. The present study aimed to investigate the expression and potential target of miR-92b-3p in angiotensin II (Ang-II)-induced mouse cardiac hypertrophy. MiR-92b-3p was markedly decreased in the myocardium of Ang-II infused mice and of patients with cardiac hypertrophy. However, miR-92b-3p expression was revealed increased in Ang-II-induced neonatal mouse cardiomyocytes. Cardiac hypertrophy was shown attenuated in Ang-II-infused mice received tail vein injection of miR-92b-3p mimic. Moreover, miR-92b-3p inhibited the expression of atrial natriuretic peptide (ANP), skeletal muscle alpha-actin (ACTA1) and beta-myosin heavy chain (MHC) in Ang-II-induced mouse cardiomyocytes in vitro. Myocyte-specific enhancer factor 2D (MEF2D), which was increased in Ang II-induced mouse hypertrophic myocardium and cardiomyocytes, was identified as a target gene of miR-92b-3p. Functionally, miR-92b-3p mimic, consistent with MEF2D siRNA, inhibited cell size increase and protein expression of ANP, ACTA1 and beta MHC in Ang-II-treated mouse cardiomyocytes. Taken together, we demonstrated that MEF2D is a novel target of miR-92b-3p, and attenuation of miR-92b-3p expression may contribute to the increase of MEF2D in cardiac hypertrophy. PMID- 29190900 TI - Immuno-PET imaging based radioimmunotherapy in head and neck squamous cell carcinoma model. AB - The epidermal growth factor receptor (EGFR) is one of the most comprehensively studied molecular targets in head and neck squamous cell carcinoma (HNSCC). However, inherent and acquired resistance are serious problems and are responsible for limited clinical efficacy and tumor recurrence. In this study, we evaluated the feasibility of immuno-positron emission tomography (PET) imaging and radioimmunotherapy (RIT) with 64Cu-/177Lu-PCTA-cetuximab in cetuximab resistant SNU-1066 HNSCC xenografted model. The cellular uptake of 64Cu/177Lu 3,6,9,15-tetraazabicyclo[9.3.1]-pentadeca-1(15),11,13-triene-3,6,9,-triacetic acid (PCTA)-cetuximab showed good correlation with western blot and flow cytometry analysis in EGFR expression level of various HNSCC cells. 177Lu-PCTA cetuximab selectively killed cetuximab-resistant SNU-1066 cells in vitro. 64Cu /177Lu-PCTA-cetuximab specifically accumulated in SNU-1066 tumor and those uptakes were peaked at 48 h and 7 day, respectively in biodistribution, PET and single-photon emission computed tomography/computed tomography (SPECT/CT) imaging. RIT with single dose of 177Lu-PCTA-cetuximab exhibited significant tumor regression and markedly reduced 2-[18F]fluoro-2-deoxy-D-glucose (18F-FDG) uptake, compared to other groups. Proliferation index were dramatically decreased and apoptotic index increased in RIT group. These results suggest that a diagnostic and therapeutic convergence radiopharmaceutical, 64Cu-/177Lu-PCTA-cetuximab has the potential of target selection using immuno-PET imaging and targeted therapy by RIT in EGFR expressing cetuximab-resistant HNSCC tumors. PMID- 29190901 TI - KIF11 is required for proliferation and self-renewal of docetaxel resistant triple negative breast cancer cells. AB - Development of chemoresistance remains a major hurdle for triple negative breast cancer treatment. Previous studies suggest that CD44+/CD24- cells, subpopulation of cancer stem cells with self-renewing and tumor-initiating capacities, are partly responsible for chemoresistance and therapeutic failure of triple negative breast cancer. Therefore, novel agents that target cancer stem cells (CSCs) may improve the clinical outcome. KIF11 (kinesin family member 11), overexpressed in many cancer cells, is a molecular motor protein that plays essential role in mitosis. In this study, we assess its role in docetaxel resistant triple negative breast cancer (TNBC). We found that the expression of KIF11 was significantly increased in CD44+/CD24- subpopulation of docetaxel resistant TNBC cells. Knockdown of KIF11 resulted in a significant decrease in the percentage of CSCs and mammosphere formation. KIF11 knockdown also inhibits cell growth and induces cell cycle G2/M arrest followed by cell mitosis and apoptosis. Further docetaxel resistant TNBC xenograft models demonstrated that KIF11 inhibitor exerts growth inhibitory effect in vivo. Of note, we also found that KIF11 was highly expressed in TNBC and its expression was correlated with shorter disease free survival time. All these data indicate that KIF11 is critical for proliferation and self renewal in TNBC tumor cells in vitro and in vivo, suggesting that KIF11 may be a promising therapeutic target for treating chemoresistant TNBC. PMID- 29190902 TI - MicroRNA-212 inhibits the proliferation, migration and invasion of renal cell carcinoma by targeting X-linked inhibitor of apoptosis protein (XIAP). AB - MicroRNAs have been found to be critical regulator of cancer cell biology. MicroRNA-212 (miR-212) was identified to be a critical cancer-associated microRNA playing either oncogenic functions or tumor suppressive roles in different types of human cancers. In this study, we found that the level of miR-212 in renal cell carcinoma (RCC) tissues was significantly lower than that in adjacent non-tumor tissues. Decreased level of miR-212 was associated with advanced T stage and TNM stage of RCC. The expression of miR-212 was decreased in RCC cell lines as compared with the HK-2 cell line. Overexpression of miR-212 inhibited cell viability, proliferation, migration and invasion of CAKI-2 cells. Knockdown of miR-212 increased cell viability and proliferation, migration and invasion of ACHN cells. In vivo experiments showed that miR-212 inhibited the proliferation and promoted the apoptosis of ACHN cells in nude mice and thus inhibited the in vivo tumor growth of CAKI-2 cells. Furthermore, we confirmed that X-linked inhibitor of apoptosis protein (XIAP) was the downstream target of miR-212. The expression level of miR-212 was negatively correlated with XIAP expression in RCC tissues. Moreover, XIAP mediated the tumor suppressive roles of miR-212 in RCC. Finally, we demonstrated that the aberrant expression of miR-212 and XIAP was evidently correlated with poor prognosis of RCC patients. In all, miR-212 can act as a prognostic biomarker for RCC patients and inhibits the growth and metastasis of RCC cells by inhibiting XIAP. PMID- 29190903 TI - Downregulation of tumor suppressive microRNAs in vivo in dense breast tissue of postmenopausal women. AB - Women with dense breast tissue on mammography are at higher risk of developing breast cancer but the underlying mechanisms are not well understood. De regulation of microRNAs (miRNAs) has been associated with the onset of breast cancer. miRNAs in the extracellular space participate in the regulation of the local tissue microenvironment. Here, we recruited 39 healthy postmenopausal women attending their mammography-screen that were assessed having extreme dense or entirely fatty breasts (nondense). Microdialysis was performed in breast tissue and a reference catheter was inserted in abdominal subcutaneous fat for local sampling of extracellular compounds. Three miRNAs, associated with tumor suppression, miR-193b, miR-365a, and miR-452 were significantly down-regulated in dense breast tissue compared with nondense breast tissue. In addition, miR-452 exhibited significant negative correlations with several pro-inflammatory cytokines in vivo, which was confirmed in vitro by overexpression of miR-452 in breast cancer cells. No differences were found of miR-21, -29a, -30c, 146a, 148a, -203, or -451 in breast tissue and no miRs were different in plasma. Extracellular miRNAs may be among factors that should be included in studies of novel prevention strategies for breast cancer. PMID- 29190904 TI - Measurements of heterotypic associations between cluster of differentiation CD74 and CD44 in human breast cancer-derived cells. AB - Interactions between pairs of membrane-bound receptors can enhance tumour development with implications for targeted therapies for cancer. Here we demonstrate clear heterotypic interaction between CD74 and CD44, which might act in synergy and hence contribute to breast cancer progression. CD74, a type II transmembrane glycoprotein, is a chaperone for MHC class II biosynthesis and a receptor for the MIF. CD44 is the receptor for hyaluronic acid and is a Type I transmembrane protein. Interactions between CD74, MIF and the intra-cytoplasmic domain of CD44 result in activation of ERK1/2 pathway, leading to increased cell proliferation and decreased apoptosis. The level of CD44 in the breast tumor cell lines CAMA-1, MDA-MB-231, MDA-MB-435 and the immortalized normal luminal cell line 226LDM was higher than that of CD74. It was also observed that CD74 and CD44 exhibit significant variation in expression levels across the cells. CD74 and CD44 were observed to accumulate in cytoplasmic compartments, suggesting they associate with each other to facilitate tumour growth and metastasis. Use of a novel and validated colocalisation and image processing approach, coupled with co immunoprecipitation, confirmed that CD74 and CD44 physically interact, suggesting a possible role in breast tumour growth. This is the first time that CD74 and CD44 colocalization has been quantified in breast cancer cells using a non invasive and validated bioimaging procedure. Measuring the co-expression levels of CD74 and CD44 could potentially be used as a 'biomarker signature' to monitor different stages of breast cancer. PMID- 29190905 TI - The exon 38-containing ARHGEF11 splice isoform is differentially expressed and is required for migration and growth in invasive breast cancer cells. AB - Breast cancer invasion involves the loss of cell-cell junctions and acquisition of an invasive, migratory phenotype, and breast cancer cells of the basal intrinsic subtype are more invasive and metastatic than breast cancer cells of other subtypes. ARHGEF11 is a RhoGEF that was previously shown to bind to the tight junction protein ZO-1 at perijunctional actomyosin ring (PJAR), a network of cortically organized actin and myosin filaments associated with junctional complexes that regulates cell-cell adhesion and polarization. We show here that ARHGEF11 shows splice isoform expression that differs according to the intrinsic subtype of breast cancer cells and that controls their invasive phenotype. Luminal subtype breast cancer cells express the isoform of ARHGEF11 lacking exon 38 (38-), which binds to ZO-1 at PJAR and is necessary for formation and maintenance of cell-cell junctions. Basal subtype breast cancer cells express the isoform of ARHGEF11 containing exon 38 (38+), which does not bind to ZO-1 and which drives cell migration and motility. Depletion of ARHGEF11 in basal subtype breast cancer cells is sufficient to alter cell morphology from a mesenchymal stellate form with extensive cell protrusions to a cobblestone-like epithelial form, and to suppress growth and survival both in vitro and in vivo. These findings show that the expression of the particular splice isoform of ARHGEF11 is critically linked to the malignant phenotype of breast cancer cells, identifying ARHGEF11 exon 38(+) as a biomarker and target for therapy of breast cancer. PMID- 29190906 TI - Improved prognostic stratification using NCCN- and GELTAMO-international prognostic index in patients with diffuse large B-cell lymphoma. AB - The National Comprehensive Cancer Network (NCCN)-International Prognostic Index (IPI) and GELTAMO (Grupo Espanol de Linfomas/Trasplante Autologo de Medula Osea) IPI were developed to enable better risk prediction of patients with diffuse large B-cell lymphoma (DLBCL). The present study compared the effectiveness of risk prediction between IPI, NCCN-IPI, and GELTAMO-IPI in patients with DLBCL particularly in terms of determining high-risk patients. Among 439 patients who were enrolled to a prospective DLBCL cohort treated with R-CHOP immunochemotherapy, risk groups were classified according to the three IPIs and the prognostic significance of individual IPI factors and IPI models were analyzed and compared. All three IPI effectively separated the analyzed patients into four risk groups according to overall survival (OS). Estimated 5-year OS of patients classified as high-risk according to the IPI was 45.7%, suggesting that the IPI is limited in the selection of patients who are expected to have a poor outcome. In contrast, the 5-year OS of patients stratified as high-risk according to NCCN- and GELTAMO-IPI was 31.4% and 21.9%, respectively. The results indicate that NCCN- and GELTAMO-IPI are better than the IPI in predicting patients with poor prognosis, suggesting the superiority of enhanced, next-generation IPIs for DLBCL. PMID- 29190907 TI - Profile of differentially expressed Toll-like receptor signaling genes in the natural killer cells of patients with Sezary syndrome. AB - Sezary syndrome (SS), an aggressive and leukemic form of cutaneous T-cell lymphoma, usually results in shortened survival. Improving innate immunity in SS by targeting natural killer (NK) cells with Toll-like receptor (TLR) agonists could be an interesting modulatory strategy. We evaluated the NK cell populations in SS patients assessing activating and inhibitory receptors expression and profiled the differential expression of TLR signaling pathway genes in unstimulated NK cells and after TLR7/8 stimulation. We observed preserved CD56bright NK cells and a low percentage of CD56dim NK cells in the peripheral blood of SS patients compared to those in the healthy control group. Both NK cell populations showed down-modulation of NKG2C and NKG2D expression, which was associated with high serum levels of the soluble form of NKG2D ligands. In contrast, an expansion of "memory" CD57+ NKG2C+ NK cells and high cytomegalovirus antibody titers were detected in SS patients. Profiling of the TLR signaling genes in NK cells from SS patients showed an abundance of differentially expressed genes (DEGs) in NK cells in the unstimulated condition, with mostly up regulation of NFkappaB/JNK p38 pathway genes, but there was down-regulation of type I (IFN-alpha/beta) and II (IFN-gamma) interferon and IL-12A. After activation of NK cells with TLR7/8 agonist, the down-regulated genes correlated with the IFN response, and IL-12 became up-regulated, together with other antitumor factors. NK cell activation with a dual agonist for TLR7 and TLR8 is able to induce the expression of IFN-gamma and type I IFN, which can improve immunity in SS patients. PMID- 29190908 TI - EGFR-targeted nonviral NIS gene transfer for bioimaging and therapy of disseminated colon cancer metastases. AB - Liver metastases present a serious problem in the therapy of advanced colorectal cancer (CRC), as more than 20% of patients have distant metastases at the time of diagnosis with less than 5% being cured. Consequently, new therapeutic approaches are of major need together with high-resolution imaging methods that allow highly specific detection of small metastases. The unique combination of reporter and therapy gene function of the sodium iodide symporter (NIS) may represent a promising theranostic strategy for CRC liver metastases allowing non-invasive imaging of functional NIS expression and therapeutic application of 131I. For targeted NIS gene transfer polymers containing linear polyethylenimine (LPEI), polyethylene glycol (PEG) and the epidermal growth factor receptor (EGFR) specific ligand GE11 were complexed with human NIS DNA (LPEI-PEG-GE11/NIS). Tumor specificity and transduction efficiency were examined in high EGFR-expressing LS174T metastases by non-invasive imaging using 18F-tetrafluoroborate (18F-TFB) as novel NIS PET tracer. Mice that were injected with LPEI-PEG-GE11/NIS 48 h before 18F-TFB application showed high tumoral levels (4.8+/-0.6% of injected dose) of NIS-mediated radionuclide uptake in comparison to low levels detected in mice that received untargeted control polyplexes. Three cycles of intravenous injection of EGFR-targeted NIS polyplexes followed by therapeutic application of 55.5 MBq 131I resulted in marked delay in metastases spread, which was associated with improved animal survival. In conclusion, these preclinical data confirm the enormous potential of EGFR-targeted synthetic polymers for systemic NIS gene delivery in an advanced multifocal CRC liver metastases model and open the exciting prospect of NIS-mediated radionuclide therapy in metastatic disease. PMID- 29190909 TI - Genes co-amplified with ERBB2 or MET as novel potential cancer-promoting genes in gastric cancer. AB - Gastric cancer (GC), one of the most common cancers worldwide, has a high mortality rate due to limited treatment options. Identifying novel and promising molecular targets is a major challenge that must be overcome if treatment of advanced GC is to be successful. Here, we used comparative genomic hybridization and gene expression microarrays to examine genome-wide DNA copy number alterations (CNAs) and global gene expression in 38 GC samples from old and young patients. We identified frequent CNAs, which included copy number gains on chromosomes 3q, 7p, 8q, 20p, and 20q and copy number losses on chromosomes 19p and 21p. The most frequently gained region was 7p21.1 (55%), whereas the most frequently deleted region was 21p11.1 (50%). Recurrent highly amplified regions 17q12 and 7q31.1-7q31.31 harbored two well-known oncogenes: ERBB2 and MET. Correlation analysis of CNAs and gene expression levels identified CAPZA2 (co amplified with MET) and genes GRB7, MIEN1, PGAP3, and STARD3 (co-amplified with ERBB2) as potential candidate cancer-promoting genes (CPGs). Public dataset analysis confirmed co-amplification of these genes with MET or ERBB2 in GC tissue samples, and revealed that high expression (except for PGAP3) was significantly associated with shorter overall survival. Knockdown of these genes using small interfering RNA led to significant suppression of GC cell proliferation and migration. Reduced GC cell proliferation mediated by CAPZA2 knockdown was attributable to attenuated cell cycle progression and increased apoptosis. This study identified novel candidate CPGs co-amplified with MET or ERBB2, and suggests that they play a functional role in GC. PMID- 29190910 TI - The tissue distribution and significance of B7-H4 in laryngeal carcinoma. AB - The costimulatory signals CD28 and B7 have been shown to control tumor invasion and metastasis by regulating T cell activation, whereas the distribution characteristics of B7-associated proteins in laryngeal carcinoma (LC) tissue are still unclear. Here, the expression of members of the B7 superfamily, including B7-H1 (PD-L1), B7-DC (PD-L2) and B7-H4, in fifty-two LC samples was determined by immunohistochemistry, and the relationship between B7-H4 and epithelial mesenchymal transition (EMT)-associated markers was further assessed by immunofluorescence double staining. Furthermore, the human LC cell lines, Hep-2 and TU212 cells, were further transfected to overexpress B7-H4, and cell invasion and metastasis were analyzed. The results showed that B7-H1, B7-DC and B7-H4 were expressed in the tumor cells, and their expression was restricted to the cell membrane and the cytoplasm. The positive rates of these molecules in the tumor tissues were 57.7% (30/52), 32.7% (17/52) and 34.6% (18/52), respectively. Interestingly, double immunofluorescence staining showed that B7-H4 is coexpression with EMT-related markers, including p-Smad2/3, Snail and Vimentin, in carcinoma cells. Moreover, overexpression of B7-H4 in Hep-2 cells promotes the expression of pSmad2/3 and Snail by activating AKT-STAT3 signaling. Transwell and wound-healing assays demonstrated that B7-H4 enhanced both Hep-2 and TU212 cell invasion and metastasis. Our results suggest that B7-H4 transmits feedback signaling to tumor cells and promotes invasion and metastasis by promoting EMT progression. Therefore, blocking B7-H4 signaling might be a novel treatment strategy for LC. PMID- 29190911 TI - Acquisition of EGFR TKI resistance and EMT phenotype is linked with activation of IGF1R/NF-kappaB pathway in EGFR-mutant NSCLC. AB - Epithelial-mesenchymal transition (EMT) is clinically associated with acquired resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) in non-small cell lung cancers (NSCLC). However, the mechanisms promoting EMT in EGFR TKI-resistant NSCLC have not been fully elucidated. Previous studies have suggested that IGF1R signaling is involved in both acquired EGFR TKI resistance in NSCLC and induction of EMT in some types of tumor. In this study, we further explored the role of the IGF1R signaling in the acquisition of EMT phenotype associated with EGFR TKI resistance in mutant-EGFR NSCLC. Compared to gefitinib-sensitive parental cells, gefitinib-resistant (GR) cells displayed an EMT phenotype associated with increased migration and invasion abilities with the concomitant activation of IGF1R and NF-kappaB p65 signaling. Inhibition of IGF1R or p65 using pharmacological inhibitor or specific siRNA partially restored sensitivity to gefitinib with the concomitant reversal of EMT in GR cells. Conversely, exogenous IGF1 induced both gefitinib resistance and accompanying EMT in parental cells. We also demonstrated that IGF1R could phosphorylate downstream Akt and Erk to activate NF-kappaB p65. Taken together, our findings indicate that activation of IGF1R/Akt/Erk/NF-kappaB signaling is linked to the acquisition of EGFR TKI resistance and EMT phenotype in EGFR-mutant NSCLC and could be a novel therapeutic target for advanced NSCLC. PMID- 29190913 TI - Epitope mapping of spontaneous autoantibodies to anaplastic lymphoma kinase (ALK) in non-small cell lung cancer. AB - The anaplastic lymphoma kinase (ALK) is recognized by the immune system as a tumor antigen, and preclinical evidence suggests that ALK-rearranged NSCLCs can also be successfully targeted immunologically using vaccine-based approaches. In contrast to ALK-rearranged lymphomas, the frequency and clinical significance of spontaneous ALK immune responses in patients with ALK-rearranged NSCLCs are largely unknown. We developed an enzyme-linked immunosorbent assay (ELISA) to measure anti-ALK antibody levels and mapped specific peptide epitope sequences within the ALK cytoplasmic domain in patients with non-small cell lung cancer. The ELISA method showed good correlation with ALK antibody titers measured with a standard immunocytochemical approach. Strong anti-ALK antibody responses were detected in 9 of 53 (17.0%) ALK-positive NSCLC patients and in 0 of 38 (0%) ALK negative NSCLC patients (P<0.01), and the mean antibody levels were significantly higher in ALK-positive than in ALK-negative NSCLC patients (P=0.02). Across individual patients, autoantibodies recognized different epitopes in the ALK cytoplasmic domain, most of which clustered outside the tyrosine kinase domain. Whether the presence of high ALK autoantibody levels confers a more favorable prognosis in this patient population warrants further investigation. PMID- 29190912 TI - RBP4 and THBS2 are serum biomarkers for diagnosis of colorectal cancer. AB - The potential role of serum RBP4 and THBS2 as biomarker in colorectal cancer (CRC) diagnosis has never been studied. We investigated in large sample using quantitative ELISA method to explore whether serum RBP4 and THBS2 can act as biomarkers for CRC diagnosis. The concentration of RBP4 and THBS2 was measured in 402 CRC patients' serum samples and 218 normal controls' serum samples. The results showed that the average RBP4 and THBS2 concentrations in normal controls were significantly higher than in CRC patients (36.5+/-11.4MUg/mL vs 21.8+/ 8.7MUg/mL and 20.5+/-6.1ng/mL vs 14.5+/-7.3ng/mL, respectively), both p<0.001. RBP4 distinguished CRC patients from normal individuals with the area under the receiver operating characteristic curve (AUC) performing at 0.852, with sensitivity of 74.9% and specificity of 81.7%. While THBS2 distinguished CRC patients performing AUC at 0.794, with sensitivity of 64.9% and specificity of 87.1%. The ability of RBP4 and THBS2 serum concentration distinguishing CRC from normal controls showed better than that of serum CEA (AUC=0.818) or CA19-9 (AUC=0.650) concentration. This is the first study to report RBP4 and THBS2 as diagnosis serum biomarkers for CRC, which might be a good supplement for CEA or CA19-9 for clinical diagnosis. PMID- 29190914 TI - Genomic copy number gains of ErbB family members predict poor clinical outcomes in glioma patients. AB - The aim of this study was to investigate copy number of ErbB family members (including EGFR, HER2, HER3 and HER4) in a cohort of gliomas and benign meningiomas (control subjects), and explore the associations of their copy number with clinicopathological characteristics and clinical outcomes of glioma patients. Using real-time quantitative PCR assay, we demonstrated that copy number of EGFR, HER2, HER3 and HER4 in glioma patients was significantly increased compared to control subjects. Moreover, our data also showed that the risk of cancer-related death was positively associated with copy number gain (CNG) of EGFR, HER3 and HER4, but not HER2. CNG of EGFR and HER2 was positively related to radiotherapy, while CNG of HER3 and HER4 was negatively related to chemotherapy. Importantly, EGFR CNG significantly shortened median survival times of glioma patients regardless of gender, tumor grade and therapeutic regimens. Stratified analysis showed that CNG of HER2-4 almost did not influence the survival of male patients, patients with high-grade tumors and patients receiving chemotherapy, but dramatically shortened median survival times of female patients, those with low-grade tumors and those receiving radiotherapy. Collectively, our data not only demonstrate that the members of ErbB family are frequently amplified in gliomas, but also suggest that these common genetic events may be prognostic factors for poor clinical outcomes in glioma patients. PMID- 29190915 TI - The prognostic significance of CD11b+CX3CR1+ monocytes in patients with newly diagnosed diffuse large B-cell lymphoma. AB - Despite their critical roles in angiogenesis and host immunosuppression within the tumor microenvironment, the prognostic significance of myeloid-lineage cells expressing CD11b and CX3CR1 in diffuse large B-cell lymphoma (DLBCL) has not been well studied. We prospectively enrolled newly-diagnosed DLBCL patients at two Korean institutions between May 2011 and Aug 2015. CD11b+CX3CR1+ cells were analyzed by flow cytometry using peripheral blood (PB) and bone marrow (BM) aspirate samples before treatments. Eighty-nine patients (52 males) were enrolled. The median age was 65 years (range, 19-88 years). Thirty-seven patients (42%) were classified as high-intermediate or high risk according to the National Comprehensive Cancer Network International Prognostic Index (NCCN-IPI). Patients were categorized into either high or low PB-/BM-CD11b+CX3CR1+ monocyte group according to the cutoffs identified by the receiver-operating-characteristics analysis (PB, 3.68%; BM, 3.45%). The high PB-CD11b+CX3CR1+ monocyte group was significantly associated with high-intermediate and high risk NCCN-IPI group (P = 0.004). With a median follow-up of 27.7 months (range, 1.7-60.4 months), the low PB-CD11b+CX3CR1+ monocyte group showed significantly better overall survival (OS) than the high PB-CD11b+CX3CR1+ monocyte group (3-year, 92.3% vs. 51.2%, respectively; P < 0.001). In contrast, no significant difference was observed between the high and low BM-CD11b+CX3CR1+ monocyte groups. Among patients with high-intermediate to high risk NCCN-IPI, the high PB-CD11b+CX3CR1+ monocyte group showed significantly worse OS than the low PB-CD11b+CX3CR1+ monocyte group (3 year, 29.3% vs. 80.2%, respectively; P = 0.008). Taken together, PB-CD11b+CX3CR1+ monocyte percentage correlates with the NCCN-IPI risk stratification, which enables identification of subgroups with extremely poor clinical outcomes. PMID- 29190916 TI - Coenzyme Q10 inhibits the activation of pancreatic stellate cells through PI3K/AKT/mTOR signaling pathway. AB - Aim: Pancreatic stellate cells (PSCs) have a vital role in pancreatic fibrosis accompanied by pancreatic ductal adenocarcinoma (PDAC) and chronic pancreatitis (CP). Any agents which can affect the activation of PSCs could become potential candidates for treatment strategies in PDAC and CP. Our aim was to explore the effect of Coenzyme Q10 (CoQ10) in the process of PSCs activation. Methods: Isolated PSCs from C57BL/6 mice were treated with various dosages of CoQ10 (1, 10, and 100MUM) and different time (24h, 48h, and 72 h). Effect of CoQ10 on autophagy, apoptosis, senescence and oxidative stress, as well as the activation of PSCs were analyzed by immunocytofluorescent staining, quantitative real time RT-PCR, western blotting, SA-beta-galactosidase staining, malondialdehyde and reactive oxygen species (ROS) assay. Results: Expression of alpha-smooth muscle actin, LC3II, Beclin1, Cleaved caspases-3 and Bax levels were significantly reduced in CoQ10 treatment groups. Meanwhile, compared with the control group, significant differences for the expression of desmin, P62, Bcl-2, p-PI3K, p-AKT and p-mTOR levels in CoQ10 treatment groups were found. Moreover, CoQ10 affected the secretion of extracellular matrix components for PSCs. Few SA-beta-gal positive cells were found in CoQ10 treated groups. A significant decrease in ROS positive cells and malondialdehyde levels were observed after 72 h exposure to CoQ10. Conclusions: Our finding suggests that CoQ10 inhibits the activation of PSCs by suppressing autophagy through activating the PI3K/AKT/mTOR signaling pathway. CoQ10 may act as a therapeutic agent in PSC-relating pathologies and/or anti-fibrotic approaches. PMID- 29190917 TI - Pretreatment Epstein-Barr virus DNA in whole blood is a prognostic marker in peripheral T-cell lymphoma. AB - Because there are few studies regarding the clinical impact of circulating EBV DNA in peripheral T-cell lymphomas (PTCLs), we tried to evaluate the role of EBV DNA in whole blood as a prognostic factor for PTCL. We retrospectively reviewed 110 PTCL patients with median age of 63 (20-94) years. Forty-seven patients (42.7%) showed positive results for EBV-DNA, and these patients also had stage III/IV disease, elevated lactic dehydrogenase, and low albumin level (P = 0.007, P = 0.004, P = 0.002, respectively). The 5-year overall survival (OS) and progression free survival (PFS) were 21.0% and 18.0%. Univariable analysis showed that positive EBV-DNA was related with inferior OS and PFS (P = 0.015 and P < 0.001, respectively). Multivariable analysis showed that poor performance status, extranodal involvement more than one site and positive EBV-DNA results were related with OS and PFS (P < 0.001, P < 0.001, P = 0.007 and P = 0.001, P = 0.002, P < 0.001, respectively). Using these three variables, we made a new prognostic model which classified patients on risk as follows: low, no adverse factors; intermediate, 1 factor; or high, 2-3 factors. The new prognostic model could stratify the three groups for OS and PFS better than either international prognostic index or prognostic index of PTCL-u, and showed statistical significance in PTCL, not otherwise specified. This study suggests that whole blood EBV-DNA is related with aggressive clinical characteristics and inferior survival. The new prognostic model, which incorporates EBV-DNA, could better stratify PTCL patients. PMID- 29190918 TI - Plasma lipid profiling and diagnostic biomarkers for oral squamous cell carcinoma. AB - Biological requirements for tumor cell proliferation include the sustained increase of structural, energetic, signal transduction and biosynthetic precursors. Because lipids participate in membrane construction, energy storage, and cell signaling. We hypothesized that the differences in lipids between malignant carcinoma and normal controls could be reflected in the bio-fluids. A total of 100 pre-operative plasma samples were collected from 50 oral squamous cell carcinoma (OSCC), 50 normal patients and characterize by lipid profiling using ultra performance liquid chromatography/electro spray ionization mass spectrometry (UPLC-MS). The lipid profiles of the OSCC and control samples as well as the different stages were compared. Differentially expressed lipids were categorized as glycerophospholipids and sphingolipids. All glycerophospholipids were decreased, especially phosphatidylcholine and phosphoethanolamine plasmalogens, whereas sphingolipids were increased in the OSCC patients compared to the controls. We further identified 12 staging related lipids, which could be utilized to discriminate early stage patients from advanced stage patients. In the future, the differential lipids may provide biologists with additional information regarding lipid metabolism and guide clinicians in making individualized therapeutic decisions if these results are confirmed in a larger study. PMID- 29190919 TI - Molecular characterization of pro-metastatic functions of beta4-integrin in colorectal cancer. AB - The beta4-integrin subunit has been implicated in development and progression of several epithelial tumor types. However, its role in metastases of colorectal cancer (CRC) remains elusive. To study CRC metastasis, we generated a highly invasive, metastatic cell line MC38-LM10 (LM10) by passaging mouse CRC MC38 cells ten times, using a splenic injection model of liver metastasis. Affymetrix microarray analyses of LM10 and MC38 cell lines and their corresponding liver metastases generated a gene signature for CRC metastasis. This signature shows strong upregulation of beta4-integrin in LM10 cells and corresponding metastases. Upregulation of beta4-integrin in highly aggressive LM10 cells is associated with increased migration, invasion, and liver metastases. Furthermore, stable knockdown of beta4-integrin in human CRC SW620 cells reduces Bcl-2 expression, increases apoptosis, and decreases invasion, tumorigenicity, and liver metastasis, thus resulting in significantly increased survival of mice (hazard ratio = 0.32, 95% confidence interval = 0.15-0.66, P<0.01). Patients with CRC tumors display higher beta4-integrin levels in stages 1-4 and significantly lower survival rate. Collectively, beta4-integrin plays a critical role in CRC progression, invasion, and metastasis, suggesting that it could be a potential therapeutic target for CRC patients. PMID- 29190920 TI - A cassaine diterpene alkaloid, 3beta-acetyl-nor-erythrophlamide, suppresses VEGF induced angiogenesis and tumor growth via inhibiting eNOS activation. AB - Angiogenesis is one of the hallmarks of cancer, playing an essential role in tumor growth, invasion, and metastasis. 3beta-Acetyl-nor-erythrophlamide (3-ANE), a cassaine diterpene alkaloid compound from Erythrophleum fordii, exerts various pharmacological effects, including antitumor activity. However, the effects of 3 ANE on tumor angiogenesis and its potential molecular mechanism are still unknown. Here, we demonstrated that 3-ANE inhibited the vascular endothelial growth factor (VEGF)-mediated proliferation, migration, invasion, and capillary like tube formation of human umbilical vascular endothelial cells (HUVECs), without inducing apoptosis. We also found that 3-ANE blocked angiogenesis in vivo, and suppressed tumor angiogenesis and human lung adenocarcinoma growth in the xenograft tumor model. Furthermore, we showed that 3-ANE blocked VEGF mediated endothelial nitric oxide synthase (eNOS) phosphorylation, vascular permeability and NO production in HUVECs, via disrupting the VEGF-induced association of eNOS and heat-shock protein 90 (HSP90). Our studies therefore provide the first evidence that 3-ANE inhibits tumor angiogenesis by inhibiting the VEGF-mediated eNOS activation and NO production, and 3-ANE could be a potential candidate in angiogenesis-related disease therapy. PMID- 29190921 TI - Bisphenol A deteriorates egg quality through HDAC7 suppression. AB - Bisphenol A (BPA), a synthetic substance of endocrine disrupter, widely distributes in environment and can affect the health of ovarian follicles, thereby impacting the fertilization ability and pregnancy rate. However, the underlying mechanisms regarding how BPA disrupts the egg quality have not been fully revealed. In this study, we determine that BPA treated female mice display the decreasing HDAC7 expression in ovary and eggs compared to control. Moreover, the global levels of H3K9 and H4K16 acetylation abnormally increase after BPA treatment and recover partially upon HDAC7 compensation. Collectively, our study reveals that BPA deteriorates egg quality through HDAC7 suppression. PMID- 29190922 TI - Effect of ligustrazine on preventing contrast-induced nephropathy in patients with unstable angina. AB - Objective: Our purpose was to assess the effect of ligustrazine in the prevention of contrast-induced nephropathy (CIN) in patients with unstable angina (UA). Methods: 148 patients with UA undergoing coronary angiography and/or percutaneous coronary intervention (PCI) were selected for observation; the patients were divided into a control group (group A, n=74) and a ligustrazine group (group B, n=74). Group A was given routine treatment, while group B was given routine treatment combined with ligustrazine. Serum creatinine (Scr), cystatin C and glomerular filtration rate (eGFR) concentrations were measured before and 1 day, 2 days and 3 days after treatment, and the incidence of contrast-induced nephropathy (CIN) and major cardiovascular events (MACE) were observed in both groups. Results: The Scr, Cystatin C and eGRF levels in group B were better than in group A after 1 day (OR: 2.64, 95% CI: 2.47-4.98; OR: 2.66, 95% CI: 2.62-5.77; OR: 4.02, 95% CI: 3.02-5.53, respectively), 2 days (OR: 3.58, 95% CI: 2.41-4.92; OR: 2.92, 95% CI: 2.83-5.02; OR: 3.28, 95% CI: 3.24-5.14, respectively) and 3 days of treatment (OR: 3.26, 95% CI: 2.17-4.35; OR: 2.85, 95% CI: 2.26-4.02; OR: 3.19, 95% CI: 2.53-4.34, respectively). The incidence of CIN (9.26% vs 16.67%) and MACE (7.41% vs 18.51%) of group B were significantly lower than in group A (P<0.05). Conclusions: Our study suggests that ligustrazine can reduce CIN and MACE in patients with UA when undergoing coronary angiography and/or PCI. PMID- 29190923 TI - Prognostic values of distinct CBX family members in breast cancer. AB - Chromobox (CBX) family proteins are canonical components in polycomb repressive complexes 1 (PRC1), with epigenetic regulatory function and transcriptionally repressing target genes via chromatin modification. A plethora of studies have highlighted the function specifications among CBX family members in various cancer, including lung cancer, colon cancer and breast cancer. Nevertheless, the functions and prognostic roles of distinct CBX family members in breast cancer (BC) remain elusive. In this study, we reported the prognostic values of CBX family members in patients with BC through analysis of a series of databases, including CCLE, ONCOMINE, Xena Public Data Hubs, and Kaplan-Meier plotter. It was found that the mRNA expression of CBX family members were noticeably higher in BC than normal counterparts. CBX2 was highly expressed in Basal-like and HER-2 subtypes, while CBX4 and CBX7 expressions were enriched in Luminal A and Luminal B subtypes of BC. Survival analysis revealed that CBX1, CBX2 and CBX3 mRNA high expression was correlated to worsen relapse-free survival (RFS) for all BC patients, while CBX4, CBX5, CBX6 and CBX7 high expression was correlated to better RFS in this setting. Noteworthily, CBX1 and CBX2 were associated with chemoresistance whereas CBX7 was associated with tamoxifen sensitivity, as well as chemosensitivity in breast tumors. Therefore, we propose that CBX1, CBX2 and CBX7 are potential targets for BC treatment. The results might be beneficial for better understanding the complexity and heterogeneity in the molecular underpinning of BC, and to develop tools to more accurately predict the prognosis of patients with BC. PMID- 29190924 TI - PTTG1 cooperated with GLI1 leads to epithelial-mesenchymal transition in esophageal squamous cell cancer. AB - Pituitary tumor-transforming gene-1 (PTTG1) could acquire its metastasis promoting effects via inducing epithelial-mesenchymal transition (EMT). However, its role and mechanism in EMT in esophageal squamous cell cancer (ESCC) had not been clearly elucidated. Here, we demonstrated that PTTG1 was overexpressed in ESCC cell lines and tissues especially those with lymph node metastasis. Down regulation of PTTG1 levels dampened the ESCC cells invasion, migration, proliferation ability and colony formation in vitro and inhibited the growth of mouse xenograft model of ESCC cells in vivo. In addition, our in vitro and in vivo experiments consistently showed that decreased PTTG1 led to the inhibition of EMT process. Glioma-associated oncogene homolog1 (GLI1), a key factor in HH GLI signaling pathway, was also overexpressed in ESCC cells and tissues. Mechanistic studies demonstrated that decreased PTTG1 mitigated the expression levels of GLI1 in vitro and in vivo and ChIP assay also indicated that PTTG1 cooperated with GLI1 by binding to its promoter. Furthermore, overexpression of GLI1 rescued the EMT inhibited by down regulation of PTTG1 in vitro. Together, these data suggested that PTTG1 promoted the invasion ability of ESCC cells via EMT, more important, PTTG1 participated in EMT via activating the expression of GLI1 in ESCC. PTTG1 could be a candidate biomarker for defining ESCC metastasis and useful target for therapy. PMID- 29190925 TI - Nab-paclitaxel plus S-1 in advanced pancreatic adenocarcinoma (NPSPAC): a single arm, single center, phase II trial. AB - This single-arm, phase II trial is to investigate efficacy and safety of nab paclitaxel plus S-1 as first-line treatment in advanced pancreatic cancer. Nab paclitaxel was administered at 120 mg/m2 intravenously on day 1 and 8, S-1 was given twice a day orally on day 1-14 of each 21-day cycle, for 6 cycles. The primary endpoint was objective response rate (ORR), the secondary endpoints were progression-free survival (PFS), overall survival (OS) and safety. The ORR in intent-to-treat population (N=60) by either blinded independent review (BIR) or investigator assessment was 50.0%. Median PFS (mPFS) by BIR and median OS (mOS) were 5.6 months (95%CI, 4.6 to 6.6 m) and 9.4 months (95%CI, 8.0 to 10.8m), respectively. The most common grade 3 or 4 toxicities were leukopenia/neutropenia (35%) and fatigue (8.3%). Subgroup analyses based on BIR showed a remarkable ORR (>70%) was achieved in patients with female gender, >= 50% decline from baseline CA19-9, and developed grade 3 or 4 leukopenia/neutropenia. Remarkable survival benefit was statistically significant in female (mPFS: 7.7m, mOS: 18.2m), >= 50% decline from baseline CA19-9 (mPFS: 6.8m, mOS: 11.8m), objective responders (mPFS: 6.9m, mOS: 12.2m), and ECOG of 0 at baseline (mPFS: 7.5m, mOS: 16.1m). Nab paclitaxel plus S-1 showed encouraging ORR and manageable toxicities, which is an effective alternative treatment regimen for advanced pancreatic cancer.

AB - Thrombosis is one of the most common causes of mortality in Paroxysmal nocturnal hemoglobinuria (PNH), but the predisposing factors for thrombosis are yet to be defined. In this study, we outline the clinical characters and the susceptible genes which lead to thrombotic formation in 104 patients with PNH. The results displayed that the genotypes with minor alleles of rs495828 or rs2519093 in the ABO gene were associated with high risk to thrombus formation (OR 5.95, 95% CI 1.90-18.65 and OR 6.3, 95% CI 2.01-19.79, respectively). Further, the TT haplotype was associated with a significant increased risk of thrombosis (OR=3.25, 95%CI 1.42-7.39). Multivariate regression analysis showed larger PNH clone and genotypes with rs495828/rs2519093 minor allele as independent risk factors for thrombosis in PNH. Some patients who came back for follow-up were tested for the plasma levels of vWF and factor VIII. Patients carrying the rs495828/rs2519093 minor allele had a significant higher level of vWF and factor VIII compared with those carrying the major allele. Therefore, we found for the first time that the rs495828/rs2519093 polymorphism represent an independent prognostic factor in PNH patients for thrombus formation, probably by increasing the vWF and factor VIII. PMID- 29190927 TI - Dietary apple pectic oligosaccharide improves gut barrier function of rotavirus challenged weaned pigs by increasing antioxidant capacity of enterocytes. AB - Rotavirus can lead to decreasing gut barrier function and diarrhea of children and young animals. Apple pectic oligosaccharide treatment reduced diarrhea in rotavirus-infected piglets. This study was conducted to explore whether apple pectic oligosaccharide administration could protect gut barrier function of piglets against rotavirus infection. A total of 28 crossbred weaned barrows were allotted into 2 treatments fed the diets supplementing 0 and 200 mg/kg apple pectic oligosaccharide. Half of pigs in each diet treatment were challenged by rotavirus on d 15. The whole duration of this experiment is 18 days. Rotavirus challenge increased average diarrhea index, and impaired microbiota in cecal digesta, and histology, expressions of tight-junction proteins, mucins and glucagon like peptide-2 concentrations, antioxidant capacity, endoplasmic reticulum stress, autophagy and apoptosis in jejunal mucosa of piglets. However, dietary apple pectic oligosaccharide supplementation relieved effects of rotavirus challenge on diarrhea, gut health, and antioxidant capacity, endoplasmic reticulum stress, autophagy and apoptosis of jejunal mucosa in piglets. These results suggest that apple pectic oligosaccharide administration can prevent diarrhea and damage of gut barrier function via improving antioxidant capacity that might reduce endoplasmic reticulum stress, autophagy and apoptosis of intestinal epithelial cells in rotavirus-infected piglets. PMID- 29190928 TI - Prediction model of hepatocellular carcinoma risk in Asian patients with chronic hepatitis B treated with entecavir. AB - Background: Until now, no risk score could predict hepatocellular carcinoma (HCC) in nucleos(t)ide analog (NA)-treated Asian patients. Methods: We enrolled 1325 NA naive chronic hepatitis B patients with entecavir monotherapy for >12 months, with 883 and 442 patients randomly assigned to the development and validation groups, respectively, in the risk model. Results: The cumulative probabilities of HCC were 2.4%, 4.1%, and 9.9% after 2, 3, and 5 years of treatment, respectively. In the development group, age, platelet counts, and alpha-fetoprotein levels after 12 months of treatment were the independent predictors of HCC. We converted the Cox proportional hazards regression coefficients for these predictors into risk scores and developed the APA-B model, with the total risk scores ranging from 0 to 15. The risk scores accurately categorized patients with low (0-5), medium (6-9), and high (10-15) risks in the validation group (P <0.001). The areas under the receiver operating characteristic curve for predicting HCC risk after 2, 3, and 5 years were 0.877, 0.842, and 0.827, respectively, in the development group and 0.939, 0.892, and 0.862, respectively, in the validation group. Conclusion: The proposed HCC risk prediction model exhibited excellent predictive accuracy in NA-naive Asian patients receiving entecavir therapy. PMID- 29190929 TI - Whole-lesion ADC histogram and texture analysis in predicting recurrence of cervical cancer treated with CCRT. AB - Purpose: To explore the value of whole-lesion apparent diffusion coefficient (ADC) histogram and texture analysis in predicting tumor recurrence of advanced cervical cancer treated with concurrent chemo-radiotherapy (CCRT). Methods: 36 women with pathologically confirmed advanced cervical squamous carcinomas were enrolled in this prospective study. 3.0 T pelvic MR examinations including diffusion weighted imaging (b = 0, 800 s/mm2) were performed before CCRT (pre CCRT) and at the end of 2nd week of CCRT (mid-CCRT). ADC histogram and texture features were derived from the whole volume of cervical cancers. Results: With a mean follow-up of 25 months (range, 11 ~ 43), 10/36 (27.8%) patients ended with recurrence. Pre-CCRT 75th, 90th, correlation, autocorrelation and mid-CCRT ADCmean, 10th, 25th, 50th, 75th, 90th, autocorrelation can effectively differentiate the recurrence from nonrecurrence group with area under the curve ranging from 0.742 to 0.850 (P values range, 0.001 ~ 0.038). Conclusions: Pre- and mid-treatment whole-lesion ADC histogram and texture analysis hold great potential in predicting tumor recurrence of advanced cervical cancer treated with CCRT. PMID- 29190930 TI - MicroRNA-34a functions as a tumor suppressor by directly targeting oncogenic PLCE1 in Kazakh esophageal squamous cell carcinoma. AB - Esophageal squamous cell carcinoma (ESCC) is one of the frequent malignant tumors with poor prognosis worldwide. Identifying the prognostic biomarkers and potential mechanisms of such tumors has attracted increasing interest in esophageal cancer biology. Our previous study showed that phospholipase C elipson 1 (PLCE1) expression is up-regulated and associated with disease progression in esophageal carcinoma. MicroRNAs (miRNAs) play vital roles in regulating its target gene expression. However, studies on miRNA-regulated PLCE1 expression and its cellular function are still very few. We found that miR-34a is significantly expressed lower in ESCC tissues. We further showed that PLCE1 is a direct functional target gene of miR-34a, and the functional roles of miR-34a in ESCC cell lines in vitro were also determined through gain- and loss-of-function analyses. Results revealed that miR-34a functions as a tumor suppressor by inhibiting the proliferation, migration, and EMT phenotype, as well as promoting apoptosis of ESCC cell lines. Moreover, PLCE1 is overexpressed in ESCC tumors and promotes tumorigenicity in vivo and vitro. PLCE1 expression is negatively correlated with miR-34a profiles in ESCC tissues. Our data suggest that miR-34a exerts its anti-cancer function by suppressing PLCE1. The newly identified miR 34a/PLCE1 axis partially illustrates the molecular mechanism of ESCC metastasis and represents a new candidate therapeutic target for ESCC treatment. PMID- 29190931 TI - Cancer mortality trends in an industrial district of Shanghai, China, from 1974 to 2014, and projections to 2029. AB - We aimed to characterize the trends and projections of cancer mortalities in Yangpu, an industry restructuring district of Shanghai, China. With high-quality data from the death registration system, the authors analyzed the trends in cancer mortalities during 1974-2014 and their relationship with pollution control and socioeconomic improvements. Cancer burden was projected into 2029. During 1974-2014, cancer death accounted for 28.80% of all-cause death. The 5 leading causes of cancer death were cancers of the lung & bronchus, stomach, liver, colon & rectum, and esophagus. Age-standardized mortality of all cancers was higher in men than in women (153.1/105vs. 88.8/105, p<0.001) and increased from 1974 to 1991 and decreased thereafter. The mortalities of cancers of the larynx, bladder, liver, nasopharynx, lung & bronchus, esophagus, lip oral & pharynx, stomach, kidney, and lymphoma were significantly higher in men than in women. Age standardized mortalities of cancers of the esophagus, stomach, leukemia, female nasopharynx, female bladder, liver, and bone decreased especially after the 1990s, those of the colon & rectum, kidney, prostate, pancreas, breast, gallbladder, and ovary increased significantly. Lung cancer, breast cancer, colorectal cancer, and pancreas cancer in women and lung cancer, colorectal cancer, prostate cancer, and stomach cancer in men will be the leading causes of cancer death in 2025-2029. Cancer-caused life loss kept increasing since 2000. Conclusively, cancers associated with pollutions and infection decreased, especially after the 1990s, while those related to metabolic syndrome increased. These trends are related to closedown of polluted industries in the 1980s and lifestyle changes. PMID- 29190932 TI - Multigene methylation analysis of enriched circulating tumor cells associates with poor progression-free survival in metastatic breast cancer patients. AB - Blood-based biomarkers such as circulating tumor cells (CTCs) provide dynamic real-time assessment of molecular tumor characteristics beyond the primary tumor. The aim of this study was to evaluate the feasibility of a size-based microfilter to assess multigene methylation analysis of enriched CTCs in a prospective proof of principle study. We examined the quantitative methylation status of nine genes (AKR1B1, BMP6, CST6, HOXB4, HIST1H3C, ITIH5, NEUROD1, RASSF1, SOX17) in enriched CTCs from metastatic breast cancer patients. Feasibility and clinical performance testing were assessed in a test set consisting of 37 patients and 25 healthy controls. With established cut-off values from the healthy control group, methylation of enriched CTCs was detected in at least one gene in 18/37 patients (48.6%), while 97.8% of all control samples were unmethylated. Patients with CTCs unmethylated for CST6, ITIH5, or RASSF1 showed significantly longer PFS compared to patients with corresponding enriched methylated CTCs. This proof-of-principle study shows the feasibility of a size-based microfilter to enrich and analyze multigene methylation profile of CTCs from metastatic breast cancer patients. For the first time, we report that multigene methylation analysis of enriched CTCs provides prognostic information in metastatic breast cancer patients. PMID- 29190933 TI - The anticipating value of PLK1 for diagnosis, progress and prognosis and its prospective mechanism in gastric cancer: a comprehensive investigation based on high-throughput data and immunohistochemical validation. AB - Polo-like kinase 1 (PLK1) is a multi-functional protein and its aberrant expression is a driver of cancerous transformation and progression. To increase our understanding of the clinical value and potential molecular mechanism of PLK1 in gastric cancer (GC), we performed this comprehensive investigation. A total of 25 datasets and 12 publications were finally incorporated. Additional immunohistochemistry was conducted to validate the expression pattern of PLK1 in GC. The pooled standard mean deviation (SMD) indicated that PLK1 mRNA was up regulated in GC (SMD=1.21, 95% CI: 0.65-1.77, P< 0.001). Similarly, the pooled odds ratio (OR) revealed that PLK1 protein was overexpressed in GC compared with normal gastric tissue (OR=12.12, 95% CI: 5.41-27.16, P<0.001). The area under the curve (AUC) of the summary receiver operating characteristic (SROC) curve was 0.86. Furthermore, our results demonstrated that GC patients with PLK1 overexpression were significantly associated with unfavorable overall survival (HR =1.54, 95% CI: 1.30-1.83, P<0.001), lymph node metastasis (OR = 1.78, 95% CI: 1.13-2.80, P=0.013) and advanced TNM stage (OR=1.48, 95% CI: 1.02-2.15, P=0.038). Altogether, 100 similar genes were identified by Gene Expression Profiling Interactive Analysis (GEPIA) and further with gene-set enrichment analysis. These genes were related to gene ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways relevant to the cell cycle. Gene set enrichment analysis (GSEA) indicated that PLK1 is associated with various cancer-related pathways. Collectively, this study suggests that PLK1 overexpression could play vital roles in the carcinogenesis and deterioration of GC via regulating tumor related pathways. PMID- 29190934 TI - Red blood cell distribution width as a predictor of survival in nasal-type, extranodal natural killer/T-cell lymphoma. AB - We retrospectively enrolled 191 nasal-type, extranodal natural killer/T-cell lymphoma (ENKTL) patients newly diagnosed from 2008 to 2016 at the Sichuan Cancer Hospital, in order to evaluate the relationship between disease outcomes, demographic and clinical factors, and red blood cell distribution width (RDW). C index, fisher's exact test, univariate analysis, and cox regression analysis were applied. The median age of patients was 44 years and 134 (70%) were men. The cutoff of RDW was 46.2 fL determined by Cutoff Finder. Patients with RDW<=46.2 fL had significantly better progression-free survival (PFS) (3-year PFS, 80.4% vs. 63.1%; P=0.01) and overall survival (OS) (3-year OS, 83.2% vs. 65.5%; P=0.004) than those with RDW>46.2 fL. Multivariate analysis demonstrated that elevated RDW is an independent adverse predictor of OS (P=0.021, HR=2.04). RDW is an independent predictor of survival outcomes in ENKTL, which we found to be superior to both the prognostic index of natural killer lymphoma (PINK) and the Korean Prognostic Index (KPI) in discriminating patients with different outcomes in low-risk and high-risk groups (all P < 0.05). The new models combining RDW with the International Prognostic Index (IPI), KPI, and PINK showed more powerful prognostic value than corresponding original models. RDW represents an easily available and inexpensive marker for risk stratification in patients with ENKTL treated with radiotherapy-based treatment. Further prospective studies are warranted to confirm the prognostic value of RDW in ENKTL. PMID- 29190935 TI - Reduced expression of chemerin is associated with poor clinical outcome in acute myeloid leukemia. AB - Chemerin is dysregulation in numerous solid cancers. However, only little is known about the role of chemerin in acute myeloid leukemia (AML). In this study, we aimed to investigate the expression and clinical significance of recently described chemerin in acute myeloid leukemia (AML). The expression of chemerin in 149 patients with de novo AML and 35 normal controls was quantified by Real-time quantitative PCR (RQ-PCR). Chemerin was down-expressed in AML compared with controls (P=0.042). A receiver operating characteristic (ROC) curve revealed that chemerin expression could differentiate patients with AML from control subjects (AUC=0.611, 95% CI: 0.490-0.732; P=0.042) respectively. The cohort of AML patients was divided into two groups according to the cut-off value of 0.0826 (79% sensitivity and 54% specificity, respectively). In addition, the AML patients with low chemerin expression had significantly shorter overall survival (OS) than those with high chemerin expression (P=0.049). Moreover, multivariate survival analysis confirmed that chemerin was an independent prognostic factor for AML patients. In conclusion, downregulation of chemerin might be a useful diagnostic and prognostic factor for AML patients. PMID- 29190936 TI - MiR-145 inhibits the epithelial-to-mesenchymal transition via targeting ADAM19 in human glioblastoma. AB - In recent years, increasing studies demonstrated that miR-145 plays a tumor suppressor role in many human cancers. In the present study, we evaluated the expression of miR-145 and A Disintegrin and Metalloproteinase 19 (ADAM19) in glioblastoma multiforme (GBM) tissues and cells. Furthermore, we investigated the mechanisms underlying miR-145/ADAM19-induced GBM biology. Here, we found that miR 145 expression was down-regulated, while ADAM19 expression was up-regulated in GBM tissues and cells. Moreover, miR-145 mimics repressed U87 and U251 cell proliferation, migration and invasion. miR-145 mimics also inhibited the epithelial-to-mesenchymal transition (EMT) of U87 and U251 cells. Mechanically, the 3' untranslated region (3'-UTR) of ADAM19 mRNA was a direct target for miR 145. In addition, ADAM19 over-expression also partially abrogated miR-145 inhibited EMT. In conclusion, this work suggested that high miR-145 expression inhibited EMT of GBM cells by targeting ADAM19. Thus miR-145/ADAM19 can be suggested as a novel target for GBM patients. PMID- 29190937 TI - 18F-fluorodeoxyglucose positron emission tomography-computed tomography as a screening tool for second primary cancers in cancer patients. AB - Background: We performed a meta-analysis to evaluate the value of 18F fluorodeoxyglucose positron emission tomography-computed tomography (18FDG PET CT) for the detection of second primary cancers in cancer patients. Results: This present study analyzed a total of 6 selected studies (1374 patients). The sensitivity and specificity of PET-CT were 0.84 (95% confidence interval [CI] = 0.66 to 0.93), and 0.98 (95% CI = 0.97 to 0.98). Area under the curve was 0.98 (95% CI = 0.96 to 0.99). Methods: Studies were systematically searched for relevant PET-CT original articles in the MEDLINE and EMBASE databases. We calculated the pooled sensitivity, specificity, and likelihood ratios for 18FDG PET-CT. We also constructed the summary receiver-operating characteristic curve for 18FDG PET-CT. Conclusions: 18FDG PET-CT has high sensitivity and specificity for the detection of second primary cancers in cancer patients. PMID- 29190938 TI - Enhanced killing of HepG2 during cryosurgery with Fe3O4-nanoparticle improved intracellular ice formation and cell dehydration. AB - Cryosurgery is a minimally invasive treatment that utilize extreme low temperatures to destroy abnormal tissues. The clinical monitoring methods for cryosurgery are almost based on the visualization of the iceball. However, for a normal cryosurgery process, the effective killing region is always smaller than the iceball. As a result, the end of the cryosurgery process can only be judged by the surgeons according to their experience. The subjective judgement is one of the main reasons for poor estimation of tumor ablation, and it sparks high probability of recurrence and metastasis associate with cryosurgery. Being different from the previous optimization studies, we develop a novel approach with the aid of nanoparticles to enlarge the effective killing region of entire iceball, and thus it greatly decrease the difficulty of precise judgement of the cryosurgery only by applying the common clinical imaging methods. To verify this approach, both the experiments on a tissue-scale phantom with embedded living HepG2 cells in agarose and on a cell-scale cryo-microscopic freeze-thaw stage are performed. The results indicate that the introduction of the self-synthesized Fe3O4 nanoparticles significantly improved cell killing in the cryosurgery and the range of killing is extended to the entire iceball. The potential mechanism is further revealed by the cryo-microscopic experiments, which verifies the presence of Fe3O4 nanoparticles can significantly enhance the probability of intracellular ice formation and the cell dehydration during freezing hence it promote precise killing of the cells. These findings may further promote the widespread clinical application of modern cryosurgery. PMID- 29190939 TI - Early antagonism of cerebral high mobility group box-1 protein is benefit for sepsis induced brain injury. AB - Sepsis induced brain injury acts as an acute complication and accounts for deterioration and high mortality rate of septic condition. HMGB1 is a late inflammatory mediator that plays a critical role in brain dysfunction and diseases. However, the role of HMGB1 in sepsis induced brain dysfunction remains intricate. The current study investigated the effect of HMGB1 on brain injury in septic mice model with intracerebroventricular injection of BoxA (a specific antagonist of HMGB1). The expression of HMGB1, morphological changes of brain tissues, apoptosis of brain cells, and alteration of behavior were determined. The expressions of HMGB1 in cortex, hippocampus, and striatum were significantly enhanced in the sepsis group when compared with the sham group. In septic conditions, brain tissues showed significant abnormalities in tissue structure, and increased apoptosis of brain cells which was caspase-3 dependent. Septic mice showed suppression of locomotor activity and impairment of memory and learning. Neutralizing brain HMGB1 significantly improved brain injury and apoptosis of brain cells, and further ameliorated disturbed locomotor activities and damaged memory and learning. However, no significant improvement of survival rate was seen after inhibiting central HMGB1. These results reveal that HMGB1 is a potential target for ameliorating sepsis induced brain injury with early antagonizing. PMID- 29190940 TI - Elevation of MAP17 enhances the malignant behavior of cells via the Akt/mTOR pathway in hepatocellular carcinoma. AB - MAP17, a small non-glycosylated membrane protein, was significantly up-regulated in hepatocellular carcinoma (HCC) tissues in our previous genome-wide microarray analysis. In this study, quantitative real-time RT-PCR and immunohistochemistry were applied to examine MAP17 mRNA and protein expression in primary HCC and matched peritumoral tissues. The disease-free survival (DFS) and overall survival (OS) was estimated using the Kaplan-Meier analysis. The expression of MAP17 was significantly higher in HCC tissues compared to the paired peritumoral tissues at both mRNA and protein levels. High MAP17 expression was positively correlated with gender, distant metastasis, early recurrence (<= 2 year), and serum alpha fetoprotein (all p < 0.05). Kaplan-Meier analysis showed that the DFS (p = 0.004) and OS (p = 0.013) in HCC patients with elevated expression of MAP17 were much worse than that in the low expression subgroup. High level of MAP17 was also significantly associated with a high probability of HCC early recurrence after surgical resection (p = 0.005). Cox regression analysis indicated MAP17 was an independent prognostic factor for DFS (HR, 1.710; 95% CI, 1.156-2.449, p = 0.012) and OS (HR, 1.743; 95% CI, 1.152-2.639, p = 0.009) in HCC. Silencing MAP17 significantly inhibited the proliferation, invasion and migration of HCC cells in vitro, and decreased the expression levels of Akt, p-Akt (Ser473), mTOR, p-mTOR (Ser2448) and MMP-9. Suggesting MAP17 was a novel diagnostic and prognostic biomarker for HCC patients and promoted HCC cell proliferation, invasion and migration via the Akt/mTOR pathway. PMID- 29190941 TI - Associations between novel genetic variants in the promoter region of MALAT1 and risk of colorectal cancer. AB - The metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), a well-known long non-coding RNA, is involved in pathogenesis and progress of multiple tumors. However, no study has been performed to investigate the relationship between the genetic variants in promoter region of MALAT1 and colorectal cancer risk. In this study, we conducted a two-stage case-control study to evaluate whether MALAT1 genetic variants were associated with colorectal cancer risk. We identified that a single nucleotide polymorphism (SNP) rs1194338 was significantly associated with the decreased colorectal cancer risk with an odds ratio (OR) of 0.70 [95% confidence interval (CI) = 0.49-0.99] in the combined stage. The subsequently stratified analyses showed that the protective effect of rs1194338 was more pronounced in several subgroups. Furthermore, gene expression profiling analysis revealed overexpression of MALAT1 mRNA in colorectal cancer tissue compared with normal controls. Confirmation studies with large sample size and further mechanistic investigations into the function of MALAT1 and its genetic variants are warranted to advance our understanding of their roles in colorectal carcinogenesis, and to aid in the development of novel and targeted therapeutic strategies. PMID- 29190942 TI - Clinical predictors of intracranial injuries on CT in infants younger than 2 years old with mild traumatic brain injury. AB - Purpose: Mild traumatic brain injury (TBI) is common in children. The aim of this study was to identify clinical predictors of intracranial injuries on computed tomography (CT) in infants younger than 2 years old with mild TBI, which allow reducing number of imaging. Results: Of 214 enrolled infants with complete data, 30 (5.8%) sustained intracranial injuries. Younger age in months, severe injury mechanism and scalp hematomas were associated with traumatic intracranial injuries on CT. 71 had scalp hematomas and 143 had no scalp hematoma. Within infants with scalp hematomas, 26 sustained intracranial injuries and 45 presented normal. Intracranial injuries were significantly correlated with larger scalp hematomas and different scalp hematoma locations. Logistic regression analysis showed that scalp hematoma and mechanism of injury in infants younger than 2 years old with mild TBI was related to intracranial injuries (hazard ratio=38.291, P=0.0001; hazard ratio=0.174, P=0.001). In subgroup of mild TBI infants with scalp hematomas, logistic regression analysis showed age, scalp hematoma size and mechanism of injury were independently associated with intracranial injuries (hazard ratio=0.299, P=0.032; hazard ratio=5.272, P=0.006; hazard ratio=0.312, P=0.030). Methods: Between 2014 and 2016, we retrospectively enrolled infants <2 years old with mild TBI. Data recorded included age, sex, mechanism of head injury, size and location of scalp hematoma, fracture and intracranial injuries on CT. Conclusion: The characteristics of scalp hematomas and mechanism of injury were associated with intracranial injuries. These factors should be considered when making decisions on radiologic examinations of infants < 2 years old with mild TBI and alternative procedures, which do not involve ionizing radiation, should be used if appropriate. PMID- 29190943 TI - Neuroprotective effects of bajijiasu against cognitive impairment induced by amyloid-beta in APP/PS1 mice. AB - Alzheimer's disease (AD) is a progressive neurological degenerative disease. The main clinical manifestations of AD include progressive cognitive impairment and alteration of personality. Senile plaques, neuroinflammation, and destruction of synapse structure stability are the main pathological features of AD. Bajijiasu(BJJS) is extracted from Morinda Officinalis, a Chinese herb. In this study, we explored the effect of BJJS on AD from many aspects in APPswe/PSEN1DeltaE9 (APP/PS1) double transgenic mice. The Morris water maze and novel object recognition tests results showed that BJJS could significantly improve the learning and memory abilities in APP/PS1 mice. BJJS treatment increased the level of insulin degradation enzyme (IDE) and neprilysin (NEP) and decreased the level of beta-site app cleaving enzyme 1(BACE1) in the brain of APP/PS1 mice. BJJS-treated APP/PS1 mice appeared to have reductions of Abeta deposition and senile plaques, and showed higher levels of neurotrophic factors in the brain. We also found that BJJS had an inhibitory function on neuroinflammation in APP/PS1 mice. In addition, the synapse structure relevant proteins were elevated in the brain of BJJS-treated APP/PS1 mice. The present results indicated that BJJS could attenuate cognitive impairment via ameliorating the AD-related pathological alterations in APP/PS1 mice. These findings suggest that BJJS may be a potential therapeutic strategy in Alzheimer's disease. PMID- 29190944 TI - Alteration of exosomes secreted from renal tubular epithelial cells exposed to high-concentration oxalate. AB - Oxalate (Ox) is a metabolic end product that is produced by the kidneys and is associated with several pathological conditions. The accumulation of oxalate in the body is one of the factors that lead to calcium oxalate kidney stones. To simulate the high-concentration Ox environment in vivo, we established an in vitro model of high Ox using renal tubular epithelial (HK-2) cells. Cell viability and proliferation were assessed to evaluate the effects of various concentrations (0, 0.25, 0.5, 1, 2, 4, 5, 8 and 10Mm) of Ox on HK-2 cells to select the optimum concentration and time to extract the exosomes. Treatment with 0, 1, or 2 mM Ox altered the morphology and secretion capacity of exosomes. As the concentration of Ox increased, peak and mean particle size decreased, but exosomes particle concentration, exosome RNA, and exosome protein increased. Size, distribution, and rate of secretion, as well as RNA and protein content, differed among extracellular vesicle subtypes. Furthermore, the three subtypes of exosomes delivered different signal factors in the microenvironment. We therefore speculated that three subtypes of exosomes may play differing roles in intercellular signal communication and the formation of CaOx kidney stones. PMID- 29190945 TI - Serum ferritin and primary lung cancer. AB - Existing research yields conflicting results regarding the relation between iron deficiency and high serum ferritin (SF) levels in primary lung cancer patients. We investigated the concentrations of SF, hemoglobin (Hb) and transferrin (TRF) in 569 male primary lung cancer patients and 252 female primary lung cancer patients. We grouped the subjects according to gender, smoking status, menopausal status, pathological type, stage, and TNM stage. The levels of SF and TRF were correlated with T stage in male patients (p<0.01). The levels of SF and TRF were correlated with menopausal status in female patients (p<0.01). Hb was correlated with smoking status, pathological type, stage, and TNM stages in male patients(p<0.01), but in female patients, Hb was not correlated with these grouping factors(p>0.05). The levels of SF may be regulated by different mechanisms and may be of different physiological significance in different populations. PMID- 29190946 TI - beta2GPI exerts an anti-obesity effect in female mice by inhibiting lipogenesis and promoting lipolysis. AB - In humans, males compared to females have increased visceral adipose tissue which contributes to their increased risk of early death. Mice display analogous sexual diamorphism whereby females are protected from weight gain when fed a high fat diet compared to males. A role has recently been reported for beta2-glycoprotein I, an abundant plasma protein, in healthy leanness in humans. In this study we investigated the role of beta2-glycoprotein I in fat metabolism in male and female mice fed a normal chow or high fat diet. We have made a number of novel insights into factors contributing to sexual diamorphism in obesity. Female wild type mice are protected from obesity when fed a high fat diet due to down regulation of lipogenesis in the visceral adipose tissues. This down regulation is due to beta2-glycoprotein I as female mice deficient in this protein have increased levels of lipogenesis enzymes in their visceral adipose tissues with an accompanying increase in weight compared to female wild type controls. Understanding female specific regulators of obesity may lead to sex specific anti obesity therapies to address this major health problem. PMID- 29190947 TI - Thioredoxin system-mediated regulation of mutant Kras associated pancreatic neoplasia and cancer. AB - Peroxiredoxin-1 (Prdx1), a member of the thioredoxin (Txn) system, is overexpressed and correlates with poor prognosis in pancreatic cancer patients and can suppress Kras signaling through redox-mediated inhibition of ERK and AKT in lung and breast cancer. Its redox function is maintained by Txn and sulfiredoxin (Srxn), and its tumor promoting functions are activated by post translational modification. We studied the role of the Txn system in pancreatic neoplasia and cancer by determining how it regulates the phosphorylation of Kras effectors and by determining its association with patient survival. We found that elevated Prdx1 nuclear localization significantly correlated with better patient survival. Our data also demonstrate that the expression of the Txn system is dysregulated, with elevated Prdx1 expression and significantly decreased Txn and Srxn expression in pancreatic lesions of targeted mutant Kras mouse models. This correlated with distinct differences in the interconversion of Prdx1 oligomers that affect its ability to regulate ERK and AKT phosphorylation. Our data also suggest that Prdx1 post-translational modification and oligomerization suppress Prdx1 mediated redox regulation of ERK phosphorylation. We observed distinct differences in Txn expression and in the ability of pTyr-Prdx1 to bind to pERK in a PanIN model of pancreatic neoplasia as compared to an IPMN model, indicating a distinct difference in the function of post-translationally modified Prdx1 in cells with less Txn expression. Modified Txn system function and post translational regulation may therefore play a significant role in pancreatic tumorigenesis by altering Kras effector phosphorylation and inhibiting the tumor suppressive redox functions of Prdx1. PMID- 29190948 TI - Enhanced antitumor efficacy and reduced toxicity of Abnormal Savda Munziq on tumor bearing mice treated with chemotherapy. AB - Previous research has demonstrated the anti-tumor properties of Abnormal Savda Munziq (ASMq), a traditional Uyghur compound herbal medicine. The effects of ASMq on cervical carcinomas in U27 tumor-bearing mice is investigated, the effect of adding Fluorouracil (5-FU) is also assessed in this paper. The results demonstrate that ASMq and 5-FU significantly inhibited the proliferation of U27 cells in a time-dependent and dose-dependent manner. Evaluating the interactions between ASMq and 5-FU on U27 cell growth yields a combination index (CI) < 1 in different time periods, suggesting a synergistic effect between the two drugs in vitro. Nuclear magnetic resonance (NMR) analysis demonstrates that ASMq can inhibit enhanced lipid metabolism in tumor mice, enhance the glutamine content, promote lymphocyte and macrophage proliferation, and increase tumor necrosis factor(TNF-alpha) and interleukin(IL) production, which can enhance the effect of 5-FU on the inhibition of tumors. Also ASMq can reduce the content of ALT and AST in serum. Increased SOD, GSH-Px, and decreased the content of MDA in liver tissue. ASMq has a synergistic effect on liver and tumor pathology, as well as tumor inhibition rate. In addition, ASMq can also enhance the body's antioxidant capacity and improve the body's metabolism, and reduce 5-FU's toxic side effects. PMID- 29190949 TI - Association between PD-L1 expression combined with tumor-infiltrating lymphocytes and the prognosis of patients with advanced hypopharyngeal squamous cell carcinoma. AB - Limited information is available regarding the immune-related prognostic factors of patients with advanced hypopharyngeal squamous cell carcinoma (HPSCC). The expression of programmed cell death-ligand 1 (PD-L1) in tumor cells contributes to a mechanism that allows cancer cells to escape immune surveillance. We investigated whether PD-L1 or human leukocyte antigen (HLA) class I expression in tumor cells and the tumor-infiltrating lymphocyte (TIL) density were associated with the tumor response to neoadjuvant chemotherapy (NAC) and survival in patients with advanced HPSCC. We retrospectively reviewed 83 consecutive patients with stage III or IV HPSCC who received NAC. We evaluated PD-L1 and HLA class I expression and TIL density using immunohistochemistry. Univariate and multivariate analyses demonstrated that CD8+ TIL density was an independent and significant predictive factor for the response to NAC, progression-free survival (PFS) and overall survival (OS), whereas PD-L1 or HLA class I expression did not significantly correlate. The subgroup analysis revealed that a higher CD8+ TIL density without detectable PD-L1 expression tended to be associated with longer patient survival. These results suggest that PD-L1 expression levels combined with CD8+ TIL density may serve as a predictive biomarker for patients with stage III or IV HPSCC receiving NAC. PMID- 29190950 TI - Therapeutic response and long-term outcome of differentiated thyroid cancer with pulmonary metastases treated by radioiodine therapy. AB - Objective: To explore the therapeutic response (TR) and long-term outcomes of iodine-131 (I-131) treatment for patients with differentiated thyroid cancer and pulmonary metastases (DTC+PM), as well as the association between the assessment of TR and long-term outcomes. Methods: This retrospective study comprised 151 DTC+PM patients. TR was evaluated by changes in serum levels of thyroglobulin, anatomic imaging and iodine uptake in pulmonary nodules; logistic regression was applied to identify predictors. Overall survival (OS) was calculated using the Kaplan-Meier method and predictive factors of outcome by multivariate analyses. Results: After I-131 treatment, 17 patients achieved a complete response, 71 a partial response, and 63 no response. Age, pulmonary nodule size, iodine concentration within PM, extra-PM, frequency and cumulative dose of I-131 treatment were significant for TR. OS was 72.2% at 5, 55.2% at 10 and 51.3% at 15 years. After adjustment for other factors, age, pulmonary nodule size, extra-PM, frequency and cumulative dose of I-131 treatment were significant. A significant difference of survival rate in patients with different TR group was observed. Conclusions: There was a supportive response and prognosis for I-131 treatment upon DTC+PM patients. Older patients and those with non-I-131-avid PM were more likely to have no response to I-131 treatment, and greater benefits could be achieved by patients who complete treatment. Long-term outcome was better in patients with age <45 years, pulmonary nodule size <2 cm, without extra-PM, and the frequency of iodine treatment >=5 times. The predictive power of the TR on long-term prognosis was favorable. PMID- 29190951 TI - Multi-omics analysis reveals that ornithine decarboxylase contributes to erlotinib resistance in pancreatic cancer cells. AB - Molecular and metabolic alterations in cancer cells are one of the leading causes of acquired resistance to chemotherapeutics. In this study, we explored an experimental strategy to identify which of these alterations can induce erlotinib resistance in human pancreatic cancer. Using genetically matched erlotinib sensitive (BxPC-3) and erlotinib-resistant (BxPC-3ER) pancreatic cancer cells, we conducted a multi-omics analysis of metabolomes and transcriptomes in these cells. Untargeted and targeted metabolomic analyses revealed significant changes in metabolic pathways involved in the regulation of polyamines, amino acids, and fatty acids. Further transcriptomic analysis identified that ornithine decarboxylase (ODC) and its major metabolite, putrescine, contribute to the acquisition of erlotinib resistance in BxPC-3ER cells. Notably, either pharmacological or genetic blockage of ODC was able to restore erlotinib sensitivity, and this could be rescued by treatment with exogenous putrescine in erlotinib-resistant BxPC-3ER cells. Moreover, using a panel of cancer cells we demonstrated that ODC expression levels in cancer cells are inversely correlated with sensitivity to chemotherapeutics. Taken together, our findings will begin to uncover mechanisms of acquired drug resistance and ultimately help to identify potential therapeutic markers in cancer. PMID- 29190952 TI - Verrucarin J inhibits ovarian cancer and targets cancer stem cells. AB - Ovarian Cancer is the fifth leading cause of death among women from cancer. Cancer stem cells are a small population of cells present in cancer and the cause of chemoresistance and recurrence of cancer. We tested a new compound "Verrucarin J (VJ)", a metabolite of the Myrothecium fungus family, and showed that VJ significantly inhibits cell proliferation of both cisplatin-sensitive (A2780 and OVCAR5) and cisplatin-resistant (A2780/CP70) cell lines in a dose- and time dependent manner with IC50 value of approximately 10 nM after 48 h of treatment. VJ was found to induce apoptosis, DNA damage, and generation of reactive oxygen species (ROS). Treatment of A2780 cells with VJ resulted in a significant suppression of expression of CSCs markers including ALDH1, LGR5, NANOG and OCT4 in a dose-dependent manner, elimination of ALDH1+ CSC population and inhibition of expression of Notch1 and Wnt1 signaling pathways. Our study also showed that VJ inhibited the tumorigenic potential (spheroid formation on ultralow attachment plates) of isolated ALDH1+ CSCs in vitro and tumor growth and metastasis in vivo. VJ resulted downregulation of expression of securin an "oncogene" involved in tumor growth and progression, indicating that securin may serve as a downstream signaling gene to mediate antitumor effects of VJ. PMID- 29190953 TI - Distribution pattern of tumor associated macrophages predicts the prognosis of gastric cancer. AB - Purpose: As mayor biomarkers in tumor microenvironment (TME), tumor associated macrophages (TAMs) of gastric cancer (GC) still needs further studies in terms of the number and distribution pattern. Methods: Herein, tissue microarrays (TMA) incorporating 494 GC surgical samples in duplicate were stained for TAMs infiltration analysis. TAMs number was counted according to the locations, including infiltrating macrophages in cancer nest (MC), in invasive front (MF) and in stroma (MS). Correlations between TAMs number, distribution pattern and clinic-pathological features and survival analyses were performed. Results: Infiltrating macrophages number in GC tissues was much higher than that in peritumoral tissues. TAMs number was not significantly correlated with the overall survival (OS). TAMs distribution pattern could be categorized into MC or MF/MS dominant pattern, and correlated with histological grade (P =0.001). The median OS of MF/MS dominant pattern (22.1, 95%CI: 23.5-28.9) was significantly shorter than that of MC dominant pattern (25.6, 95%CI: 28.5-35.6) (P =0.002). By receiver operating characteristic curve (ROC) analysis, the predictive value of TAMs distribution pattern was superior to histological grade and pM stage, but inferior to pN and TNM stage. Conclusions: TAMs distribution pattern could be an independent prognostic factor for the OS of GC patients, and patients with MF/MS dominant pattern had worse outcomes. PMID- 29190954 TI - Cyclooxygenase-2 mediated synergistic effect of ursolic acid in combination with paclitaxel against human gastric carcinoma. AB - Ursolic acid (UA) induces apoptosis in gastric cancer cells by inhibiting cyclooxygenase-2 (COX-2). Paclitaxel (PTX) is an important chemotherapy agent used to treat solid tumors. We evaluated the in vitro antitumor activity of UA in combination with PTX against gastric cancer cells and investigated the mechanisms underlying the combined effects. A cytotoxicity test and flow cytometry were utilized to study the effects of UA and PTX on proliferation and apoptosis, respectively. To further elucidate the mechanism, Western blot analysis was used to assess changes in the expression of a series of related proteins, including COX-2, proliferating cell nuclear antigen (PCNA), Bcl-2, and Bax. UA and PTX dose and time-dependently inhibited BGC-823 and SGC-7901 gastric cancer cell proliferation. Combined delivery of UA and PTX synergistically reduced cell proliferation and induced apoptosis in these cells by lowering COX-2, PCNA, and Bcl-2 expression and by increasing Bax expression. These results indicate that the synergistic inhibition of proliferation and induction of apoptosis by UA and PTX may be induced by reducing COX-2 expression in gastric cancer cells. PMID- 29190955 TI - Concurrent administration of trastuzumab and anthracyclines as adjuvant regimen for HER2-positive breast cancer: a randomised controlled trial. AB - Background: The regimen of concurrent administration of trastuzumab and anthracyclines in the adjuvant treatment of breast cancer has never been evaluated prospectively for fear of cardiac toxicity. Methods: Patients with HER2 positive operable breast cancer were randomised to receive adjuvant treatment with concurrent or sequential administration of trastuzumab and anthracyclines. Cardiac monitoring was scheduled at baseline and every 3 months after the first dose of trastuzumab. The primary study endpoint was cardiac safety. Secondary endpoints were disease-free and overall survival. Results: From 2011 to 2014, 201 participants were enrolled and randomised. The median follow-up time was 42 months. Nineteen patients (19.4%) in the concurrent group and 22 patients (22.4%) in the sequential group met the criteria for cardiac events with non-significant difference (P=0.598). There was no difference in the mean LVEF between the two groups at the baseline and at 3, 6, 9, 12, and 24 months after the first dose of trastuzumab. No case of congestive heart failure or cardiac death occurred. The differences between the efficacies of the two regimens, defined by disease-free or overall survival, were not significant. Conclusions: Concurrent administration of trastuzumab and anthracyclines is a safe adjuvant regimen and it provides evidence for further clinical trials. PMID- 29190956 TI - Peroxiredoxin 3 maintains the survival of endometrial cancer stem cells by regulating oxidative stress. AB - Cancer stem cell (CSC)-targeted therapy could reduce tumor growth, recurrence, and metastasis in endometrial cancer (EC). The mitochondria of CSCs have been recently found to be an important target for cancer treatment, but the mitochondrial features of CSCs and their regulators, which maintain mitochondrial function, remain unclear. Here, we investigated the mitochondrial properties of CSCs, and identified specific targets for eliminating CSCs in EC. We found that endometrial CSCs displayed higher mitochondrial membrane potential, Ca2+, reactive oxygen species, ATP levels, and oxygen consumption rates than non-CSCs. Further, we also verified that mitochondrial peroxiredoxin 3 (Prx3) was upregulated, and that it contributed to the survival of CSCs in EC. The knockdown of the Prx3 gene resulted not only in decreased sphere formation, but also reduced the viability of endometrial CSCs, by causing mitochondrial dysfunction. Furthermore, we found that the forkhead box protein M1 (FoxM1), an important transcriptional factor, is overexpressed in patients with EC. FoxM1 expression correlates with elevated Prx3 expression levels, in agreement with the tumorigenic ability of Prx3 in endometrial CSCs. Taken together, our findings indicate that human endometrial CSCs have enhanced mitochondrial function compared to that of endometrial tumor cells. Endometrial CSCs show increased expression of the mitochondrial Prx3, which is required for the maintenance of mitochondrial function and survival, and is induced by FoxM1. Based on our findings, we believe that these proteins might represent valuable therapeutic targets and could provide new insights into the development of new therapeutic strategies for patients with endometrial cancer. PMID- 29190957 TI - MicroRNA-30c-5p ameliorates hypoxia-reoxygenation-induced tubular epithelial cell injury via HIF1alpha stabilization by targeting SOCS3. AB - The cellular hypoxia-reoxygenation (H/R) model is an ideal method to study ischemia-reperfusion injury, which is associated with high mortality. The role of microRNA-30c-5p (miR-30c-5p) in the H/R epithelial cell model remains unknown. In the current study, we observed a significant reduction in apoptosis when miR-30c 5p was up-regulated. We also found decreased levels of C-caspase-3 (C-CASP3) and Bcl-2-associated X (BAX) proteins and increased levels of B-cell lymphoma-2 (BCL2). Epidermal growth factor receptor (EGFR) showed similar results. Down regulating miR-30c-5p increased the levels of apoptosis and C-CASP3 and BAX expression; additionally, cell proliferation was inhibited. Hypoxia-inducible factor 1alpha (HIF1alpha) protein expression levels were up-regulated in response to up-regulation of miR-30c-5p expression. The anti-apoptotic and proliferative effects of miR-30c-5p decreased significantly after the HIF1alpha protein levels were knocked down. Using a luciferase reporter assay, we confirmed that miR-30c 5p targets suppressor of cytokine signaling-3 (SOCS3). HIF1alpha levels increased when SOCS3 was blocked. Our data show that SOCS3 expression enhances apoptosis in the H/R model. In conclusion, up-regulating miR-30c-5p protects cells from H/R induced apoptosis and induces cell proliferation; furthermore, HIF1alpha markedly contributes to this protective effect. MiR-30c-5p stabilizes HIF1alpha expression by targeting SOCS3 to achieve anti-apoptotic and proliferative effects. PMID- 29190958 TI - LncRNA BCAR4 promotes colon cancer progression via activating Wnt/beta-catenin signaling. AB - BCAR4 (Breast Cancer Anti-Estrogen Resistance 4) is a long noncoding RNA that was identified as an oncogene in breast cancer. In our research, we found that the expression level of BCAR4 was upregulated in colon cancer tissues compared to paired normal tissues. What's more, higher BCAR4 expression was correlated with lower survival rate in patients with colon cancer. Mechanistically, we showed that BCAR4 activated Wnt/beta-catenin signaling in colon cancer by protecting beta-catenin from degradation. We also showed that BCAR4 overexpression promoted cell proliferation and migration in colon cancer. However, silencing BCAR4 inhibited cell growth and promoted apoptosis. Besides, BCAR4 knockdown decreased tumor growth in vivo. These findings indicate that BCAR4 facilitated colon cancer progression by enhancing cell proliferation and inhibiting apoptosis via BCAR4/beta-catenin axis. BCAR4 may be a useful new target for treatment of patients with colon cancer. PMID- 29190959 TI - Effect of AMPK signal pathway on pathogenesis of abdominal aortic aneurysms. AB - Background and aims: Determine the effect of AMPK activation and inhibition on the development of AAA (abdominal aortic aneurysm). Methods: AAA was induced in ApoE-/- mice by Ang II (Angiotensin II)-infusion. AICAR (5-aminoimidazole-4 carboxamide-1-beta-d-ribofuranoside) was used as AMPK activator and Compound C was used as AMPK inhibitor. We further investigate the effect of metformin, a widely used anti-diabetic drug which could activate AMPK signal pathway, on the pathogenesis of aneurysm. Results: Phospho-AMPK level was significantly decreased in AAA tissue compared with control aortas. AICAR significantly reduced the incidence, severity and mortality of aneurysm in the Ang II-infusion model. AICAR also alleviated macrophage infiltration and neovascularity in Ang II infusion model at day 28. The expression of pro-inflammatory factors, angiogenic factors and the activity of MMPs were also alleviated by AICAR during AAA induction. On the other hand, Compound C treatment did not exert obvious protective effect. AMPK activation may inhibit the activation of nuclear factor-kappaB (NF-kappaB) and signal transducer and activator of transcription-3 (STAT-3) during AAA induction. Administration of metformin also activated AMPK signal pathway and retarded AAA progression in Ang II infusion model. Conclusions: Activation of AMPK signaling pathway may inhibit the Ang II-induced AAA in mice. Metformin may be a promising approach to the treatment of AAA. PMID- 29190960 TI - Interleukin-32alpha promotes the proliferation of multiple myeloma cells by inducing production of IL-6 in bone marrow stromal cells. AB - Multiple myeloma (MM) is a malignant plasma disease closely associated with inflammation. In MM bone marrow microenvironment, bone marrow stromal cells (BMSCs) are the primary source of interleukin-6 (IL-6) secretion, which promotes the proliferation and progression of MM cells. However, it is still unknown how the microenvironment stimulates BMSCs to secrete IL-6. Interleukin-32 (IL-32) is a newly identified pro-inflammatory factor. It was reported that in solid tumors, IL-32 induces changes in other inflammatory factors including IL-6, IL-10, and TNF-alpha. The aim of this study was to investigate the expression of IL-32 and the role of IL-32 in the MM bone marrow microenvironment. Our data illustrate that MM patients have higher expression of IL-32 than healthy individuals in both bone marrow and peripheral blood. We used ELISA and qRT-PCR to find that malignant plasma cells are the primary source of IL-32 production in MM bone marrow. ELISA and Western blot analysis revealed that recombinant IL-32alpha induces production of IL-6 in BMSCs by activating NF-kappaB and STAT3 signaling pathways, konckdown of IL-32 receptor PR3 inhibit this process. Knockdown of IL 32 by shRNA decreased the proliferation in MM cells that induced by BMSCs. In conclusion, IL-32 secreted from MM cells has paracrine effect to induce production of IL-6 in BMSCs, thus feedback to promote MM cells growth. PMID- 29190961 TI - Long noncoding RNA CCAT1 functions as a ceRNA to antagonize the effect of miR-410 on the down-regulation of ITPKB in human HCT-116 and HCT-8 cells. AB - Colorectal cancer is one of the most common malignancies, which has seriously affected people's health. Abnormal expression of long non-coding RNAs and microRNAs are closely related to the process of occurrence, development, invasion and metastasis of colorectal cancer. However, the effect of lnc CCAT1 on human HCT-116/HCT-8 cells and its potential mechanism were investigated. In present study, differential expression of CCAT1, miR-410 and ITPKB were detected in colon cancer tissues and adjacent parts. Then the prediction programs were applied to predict the target genes of miR-410. The complementary bindings of miR-410 with lnc CCAT1 and ITPKB were assessed by luciferase assays. The interaction between LncRNA CCAT1 and miR-410 was analyzed. In addition, the mRNA and protein of ITPKB and apoptosis factors were examined in cells after miR-410 overexpression or silencing. Meanwhile, MTT and flow cytometer were used to detect the cells proliferation and apoptosis level. Results showed that CCAT1 and miR-410 were up regulated in colon cancer tissues, but ITPKB was down-regulated. Lnc CCAT1 and ITPKB were predicted to be the targets of miR-410 and the prediction were verified by luciferase assays. The expression of lnc CCAT1 and ITPKB were inhibited by miR-410 in human HCT-116/HCT-8 cells. Meanwhile, lnc CCAT1 could lead to a decrease of miR-410. Furthermore, miR-410 overexpression could promote cell proliferation and reduce apoptosis. In summary, these data demonstrated that miR-410 could promote cell proliferation and reduce apoptosis by inhibiting ITPKB expression and the expression of lnc CCAT1 antagonized the effect of miR-410. PMID- 29190962 TI - Wu-tou decoction attenuates neuropathic pain via suppressing spinal astrocytic IL 1R1/TRAF6/JNK signaling. AB - Neuropathic pain (NP) caused by nerve injuries continues to be an intractable challenge due to inadequate therapeutic strategies. Recent study demonstrated glia-induced neuro-inflammation in the spinal cord, especially the activation of astrocytes, plays an essential role in the development of NP, which opens new avenues for NP treatment. In this study, we explored the anti-hyperalgesia properties of Wu-tou decoction (WTD) and showed that WTD potently attenuates mechanical allodynia and heat hyperalgesia in lumbar 5 (L5) spinal nerve ligation (SNL)-induced NP without noticeable side effect or affecting basal pain perception of mice. Mechanistically, initial targets screening tests indicated WTD's analgesic action may be centrally mediated within the spinal cord, which further verified by its inhibitory actions on glia-releasing factors of IL-1beta, CCL2 and CXCL1. Meanwhile, WTD significantly reduced spinal IL-1R1, TRAF6 expressions, p-JNK levels, and number of GFAP/IL-1R1, GFAP/TRAF6, GFAP/p-JNK positive astrocytes in the superficial lamina of spinal cord. Additionally, co administration of IL-1Ra increased the anti-hyperalgesia effects of WTD and further decreased CCL2 and CXCL1 expressions, while no synergistic effects were detected when TRAF6 or JNK inhibitors were co-administrated with WTD. Thus, our data suggested that the effective inhibition of spinal astrocytic IL 1R1/TRAF6/JNK signaling (especially IL-1R1) contributes, at least in part, to WTD's anti-hyperalgesia action. It also indicates that WTD might be a promising candidate for the treatments of chronic pain, especially under NP-related neurological disorders. PMID- 29190963 TI - Inter- and intra-observer reproducibility of ADC measurements in esophageal carcinoma primary tumors. AB - The apparent diffuse coefficient (ADC) may correlate with the treatment response to chemotherapy/radiotherapy in solid tumors. Our aim was to determine the inter- and intra-observer reproducibility of ADC measurements in primary esophageal squamous cell carcinoma (ESCC). ADCs were blindly measured in 31 patients diagnosed with ESCC by two observers before treatment (pre-ADC) and after 5th fraction radiotherapy (intra-ADC) twice with a 2-week interval. The mean pre-ADC of primary tumors was 1.25+/-0.22 and 1.27+/-0.23 (in 10-3mm2/s) from observer A for measurements 1 and 2, respectively, and the intra-observer measurements were 0.02 bias vs. -0.13-0.09 limits of agreement. From observer B, the mean pre-ADC varied between 1.25+/-0.23 and 1.27+/-0.23 (in 10-3mm2/s) for measurements 1 and 2, respectively, and intra-observer measurements were -0.02 bias vs. -0.17~0.16 limits of agreement. The mean pre-ADC of primary tumors was 1.26+/-0.24 (in 10 3mm2/s) from observers A and B, and inter-observer measurements were 0.01 bias vs. -0.09-0.09 limits of agreement, revealing a low inter-observer variance. Similar measurements of the intra-SD parameters showed that the pre- and intra ADC of primary tumors differed significantly. Thus ADC measurements may have sufficient inter-observer and intra-observer reproducibility to measure primary tumor responses to treatment, and the ADCs before and during treatment differed. PMID- 29190965 TI - Association between dose-volume parameters and acute bone marrow suppression in rectal cancer patients treated with concurrent chemoradiotherapy. AB - Concurrent chemoradiotherapy is one of the main treatments for rectal cancer. Bone marrow suppression is one of the critical factors that affect the progress of radiotherapy. We aimed to explore the association of incidence of acute bone marrow suppression with dose-volume parameters of pelvic bone marrow among rectal cancer patients with concurrent chemoradiotherapy. We retrospectively analyzed 50 rectal cancer patients for multivariate logistic regression analyses. Three subdomains of pelvic bone marrow (PBM), bilateral ilium (IBM), lower pelvis (LPBM), and lumbosacral spine (LSBM) were assigned. The radiation dose-volume parameters from the three subdomains and the whole pelvis were evaluated. Compared to Grade 0-1 leukopenia patients, >=Grade 2 leukopenia patients exhibited significantly higher levels of IBM V20, V25, V35, mean dose (Dmean), LPBM V20, V25, V30, LSBM V15, PBM V15, V20, and PTV. The PBM V20 of >=Grade 2 neutropenia patients was significantly higher than that of Grade 0-1 neutropenia patients. Multivariate analysis have demonstrated that IBM V20 and LSBM V15 were the independent factors affecting >= Grade 2 leukopenia. There is a correlation between low dose-volume parameters with acute bone marrow suppression. IBM V20, LSBM V15 and PBM V20 can be employed as the predictors of acute bone marrow suppression. PMID- 29190964 TI - Tumoral PD-L1 expression defines a subgroup of poor-prognosis vulvar carcinomas with non-viral etiology. AB - Vulvar cancer is rare but incidence rates are increasing due to an aging population and higher frequencies of young women being affected. In locally advanced, metastatic or recurrent disease prognosis is poor and new treatment modalities are needed. Immune checkpoint blockade of the PD-1/PD-L1 pathway is one of the most important advancements in cancer therapy in the last years. The clinical relevance of PD-L1 expression in vulvar cancer, however, has not been studied so far. We determined PD-L1 expression, numbers of CD3+ T cells, CD20+ B cells, CD68+ monocytes/macrophages, Foxp3+ regulatory T cells and CD163+ tumor associated macrophages by immunohistochemistry in 103 patients. Correlation analysis with clinicopathological parameters was undertaken; the cause-specific outcome was modeled with competing risk analysis; multivariate Cox regression was used to determine independent predictors of survival. Membranous PD-L1 was expressed in a minority of tumors, defined by HPV-negativity. Its presence geographically correlated with immunocyte-rich regions of cancer islets and was an independent prognostic factor for poor outcome. Our data support the notion that vulvar cancer is an immunomodulatory tumor that harnesses the PD-1/PD-L1 pathway to induce tolerance. Accordingly, immunotherapeutic approaches might have the potential to improve outcome in patients with vulvar cancer and could complement conventional cancer treatment. PMID- 29190966 TI - MicroRNA-21 inhibits mitochondria-mediated apoptosis in keloid. AB - MicroRNA-21 acts as an oncogene by promoting cell proliferation and migration, whereas inhibiting apoptosis in majority of cancers. MicroRNA-21 is upregulated in human keloid fibroblasts. We hypothesized that microRNA-21 may contribute to pathogenesis of keloid fibroblasts. First, enhanced miR-21 but reduced mitochondrial-mediated apoptosis observed in keloid tissues indicated its importance in keloids development. Second, upregulation of microRNA-21 induced a decrease in the ratio of BAX to BCL-2 and suppressed mitochondrial fission in keloid fibroblasts. Third, by attenuating the decline in cellular mitochondrial membrane potential, overexpression of miR-21 suppressed cytochrome c release to the cytoplasm, followed by a decrease in the activity of intracellular caspase-9 and caspase-3, suggesting that mitochondrial-mediated proapoptotic pathway was impaired. Simultaneously, intracellular reactive oxygen species were decreased, indicating microRNA-21 undermined oxidative stress. This phenotype was reversed by miR-21 inhibition. Therefore, our study demonstrates that inhibition of microRNA-21 induces mitochondrial-mediated apoptosis in keloid fibroblasts, proposing microRNA-21 as a potential therapeutic target in keloid fibroblasts. PMID- 29190967 TI - Differential prioritization of therapies to subtypes of triple negative breast cancer using a systems medicine method. AB - Triple negative breast cancer (TNBC) is a group of cancers whose heterogeneity and shortage of effective drug therapies has prompted efforts to divide these cancers into molecular subtypes. Our computational platform, entitled GenEx-TNBC, applies concepts in systems biology and polypharmacology to prioritize thousands of approved and experimental drugs for therapeutic potential against each molecular subtype of TNBC. Using patient-based and cell line-based gene expression data, we constructed networks to describe the biological perturbation associated with each TNBC subtype at multiple levels of biological action. These networks were analyzed for statistical coincidence with drug action networks stemming from known drug-protein targets, while accounting for the direction of disease modulation for coinciding entities. GenEx-TNBC successfully designated drugs, and drug classes, that were previously shown to be broadly effective or subtype-specific against TNBC, as well as novel agents. We further performed biological validation of the platform by testing the relative sensitivities of three cell lines, representing three distinct TNBC subtypes, to several small molecules according to the degree of predicted biological coincidence with each subtype. GenEx-TNBC is the first computational platform to associate drugs to diseases based on inverse relationships with multi-scale disease mechanisms mapped from global gene expression of a disease. This method may be useful for directing current efforts in preclinical drug development surrounding TNBC, and may offer insights into the targetable mechanisms of each TNBC subtype. PMID- 29190968 TI - Genetic variation at the microRNA binding site of CAV1 gene is associated with lung cancer susceptibility. AB - Single nucleotide polymorphism (SNP) may influence the genesis and development of cancer in a variety of ways depending on their location. Here we conducted a study in Chinese female non-smokers to investigate the relationship between rs1049337, rs926198 and the risk or survival of lung cancer. Further, we explored whether rs1049337 could alter the binding affinity between the mRNA of CAV1 and the corresponding microRNAs. Finally, we evaluated the relationship between expression level of CAV1 and prognosis of lung cancer. The results showed that the rs1049337-C allele and rs926198-C allele were the protective alleles of lung cancer risk. Haplotype analysis indicated that the C-C haplotype (constructed by rs1049337 and rs926198) was a protective haplotype for lung cancer risk. The result of luciferase reporter assay showed that rs1049337 can affect the binding affinity of CAV1 mRNA to the corresponding microRNAs both in A549 cell line and H1299 cell line. Compared with C allele, T allele had a relatively decreased luciferase activity. Compared with paired normal adjacent tissue or normal lung tissue, lung cancer tissue showed a relatively low level of CAV1. Refer to those patients at early stage of lung cancer, the expression level of CAV1 in patients at late stage of lung cancer was relatively low. In conclusion, the results indicated that rs1049337, it's a SNP located at 3'UTR region of CAV1 may affect lung cancer risk by altering the binding affinity between the mRNA of CAV1 and the corresponding microRNAs. PMID- 29190969 TI - Effect of oxytocin on the survival of random skin flaps. AB - Random flap transplantation is widely used to repair and rebuild skin soft tissue. However, such flaps exhibit poor survival. Plastic surgeons seek to improve flap survival. We explored whether oxytocin improved skin flap survival. Overlength random skin flaps (9 * 3 cm) were established on backs of 80 healthy male SD rats randomly divided into two groups. One group was injected daily with oxytocin (1 mg/kg; test group) and the other with normal saline (control group). On postoperative day 2, malondialdehyde (MDA) and superoxide dismutase (SOD) levels were measured. On postoperative day 7, the flap survival area was measured using transparent graph paper. Microvessel numbers were evaluated histologically by hematoxylin and eosin staining. VEGF expression was assessed immunohistochemically. Angiogenesis was evaluated via lead oxide-gelatin angiography and blood flow via laser Doppler flowmetry. In the test group compared with the control group, the flap survival rate and SOD activity were increased markedly, the MDA level was decreased, and according to hematoxylin and eosin staining, inflammation was significantly attenuated. In addition, the test group exhibited higher levels of VEGF and skin flap angiogenesis. Oxytocin improved flap survival rate by increasing microcirculation and angiogenesis and attenuating ischemia-reperfusion injury. PMID- 29190970 TI - Genome-wide identification of cancer/testis genes and their association with prognosis in a pan-cancer analysis. AB - Cancer/testis (CT) genes are excellent candidates for cancer immunotherapies because of their restrict expression in normal tissues and the capacity to elicit an immune response when expressed in tumor cells. In this study, we provide a genome-wide screen for CT genes with the identification of 745 putative CT genes. Comparison with a set of known CT genes shows that 201 new CT genes were identified. Integration of gene expression and clinical data led us to identify dozens of CT genes associated with either good or poor prognosis. For the CT genes related to good prognosis, we show that there is a direct relationship between CT gene expression and a signal for CD8+ cells infiltration for some tumor types, especially melanoma. PMID- 29190971 TI - Nomograms for predicting the overall and cancer-specific survival of patients with classical Hodgkin lymphoma: a SEER-based study. AB - The aim of this study was to establish nomograms, based on significant clinicopathologic parameters, for predicting the overall survival (OS) and the cancer-specific survival (CSS) of patients with classical Hodgkin lymphoma (CHL). The data of 43,330 CHL patients, diagnosed between 1983 and 2014, were obtainedfrom the database of the Surveillance, Epidemiology, and End Results (SEER) program. These patients were randomly divided into training (n = 30,339) and validation (n = 12,991) cohorts. The Kaplan-Meier method and Cox proportional hazards regression model were used to evaluate the prognostic effects of multiple clinicopathologic parameters on survival. Significant prognostic factors were combined to build nomograms. The predictive performance of nomograms was evaluated using the index of concordance (C-index) and calibration curves. In the training cohort, on univariate and multivariate analyses, age at diagnosis, gender, race, Ann Arbor stage, and histological type significantly correlated with the survival outcomes. These characteristics were used to establish nomograms. The nomograms showed good accuracy in predicting 1-, 5-, and 10-year OS and CSS, with a C-index of 0.794 (95% confidence interval [CI], 0.789-0.799) for OS and 0.760 (95% CI, 0.753-0.767) for CSS. In the validation cohort, the C index for nomogram-based predictions was 0.787 (95% CI, 0.779-0.795) for OS and 0.769 (95% CI, 0.758-0.780) for CSS. All calibration curves revealed excellent consistency between predicted and actual survival. In summary, novel nomograms were established and validated to predict OS and CSS for patients with CHL. These new prognostic models could aid in improved prediction of survival outcomes leading to reasonable treatment recommendations. PMID- 29190972 TI - Development of estrogen receptor beta binding prediction model using large sets of chemicals. AB - We developed an ERbeta binding prediction model to facilitate identification of chemicals specifically bind ERbeta or ERalpha together with our previously developed ERalpha binding model. Decision Forest was used to train ERbeta binding prediction model based on a large set of compounds obtained from EADB. Model performance was estimated through 1000 iterations of 5-fold cross validations. Prediction confidence was analyzed using predictions from the cross validations. Informative chemical features for ERbeta binding were identified through analysis of the frequency data of chemical descriptors used in the models in the 5-fold cross validations. 1000 permutations were conducted to assess the chance correlation. The average accuracy of 5-fold cross validations was 93.14% with a standard deviation of 0.64%. Prediction confidence analysis indicated that the higher the prediction confidence the more accurate the predictions. Permutation testing results revealed that the prediction model is unlikely generated by chance. Eighteen informative descriptors were identified to be important to ERbeta binding prediction. Application of the prediction model to the data from ToxCast project yielded very high sensitivity of 90-92%. Our results demonstrated ERbeta binding of chemicals could be accurately predicted using the developed model. Coupling with our previously developed ERalpha prediction model, this model could be expected to facilitate drug development through identification of chemicals that specifically bind ERbeta or ERalpha. PMID- 29190973 TI - CLCA4 inhibits bladder cancer cell proliferation, migration, and invasion by suppressing the PI3K/AKT pathway. AB - Calcium activated chloride channel A4 (CLCA4), a tumor suppressor, was shown to contribute to the progression of several human cancers, while its role in bladder carcinoma remains unclear. In this study, we showed CLCA4 expression was down regulated in bladder carcinoma tissues and cells compared to adjacent non-tumor tissues and normal urothelial cells. Low CLCA4 expression was correlated with larger tumor size, advanced tumor stage, and poor prognosis in bladder carcinoma patients. Overexpression of CLCA4 profoundly attenuated the proliferation, growth, migratory and invasive capabilities of bladder cancer cells, whereas CLCA4 knockdown had the opposite effect. Mechanistically, CLCA4 is involved in PI3K/AKT signaling and its downstream molecules can promote bladder cancer cell proliferation. Additionally, CLCA4 could mediate the migration and invasion of bladder cancer cells by regulating epithelial-mesenchymal transition and PI3K/Akt activation. This study suggests that CLCA4 may represent a promising prognostic biomarker for bladder cancer and provides a possible mechanism for bladder cancer growth and invasion. PMID- 29190974 TI - MiR-3613-3p affects cell proliferation and cell cycle in hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is one of the most common types of malignant tumors with poor sensitivity to chemotherapy drugs and poor prognosis among patients. In the present study, we downloaded the original data from the Gene Expression Omnibus and compared gene expression profiles of liver cancer cells in patients with HCC with those of colon epithelial cells of healthy controls to identify differentially expressed genes (DEGs). After filtering target microRNAs (miRNA) from core DEGs, we cultured HepG2 cells in vitro, knocked down the miRNA and core mRNAs, and analyzed the effects. We found 228 differentially expressed genes between liver cancer tissue and healthy control tissue. We also integrated the protein-proteininteraction network and module analysis to screen 13 core genes, consisting of 12 up-regulated genes and 1 down-regulated gene. Five core genes were regulated hsa-miR-3613-3p, therefor we hypothesized that hsa-miR-3613 3p was a critical miRNA. After the transfection procedure, we found that changes in hsa-miR-3613-3p were the most obvious. Therefore, we speculated that hsa-miR 3613-3p was a main target miRNA. In addition, we transfected with si (BIRC5, CDK1, NUF2, ZWINT and SPC24), to target genes that can be targeted by miR-3613 3p. Our data shows that BIRC5, NUF2, and SPC24 may be promising liver cancer biomarkers that may not only predict disease occurrence but also potential personalized treatment options. PMID- 29190975 TI - The association of plasma fibrinogen with clinicopathological features and prognosis in esophageal cancer patients. AB - Background: Numerous studies have shown that plasma fibrinogen was linked to esophageal cancer (EC) risk. However, the clinical significance of plasma fibrinogen in EC patients remain unclear and need to be further clarified. Results: A total of 2865 patients with EC from 11 published studies were included in this meta-analysis. The prognostic and clinical relevance of plasma fibrinogen were evaluated in EC patients. Statistical significance of the pooled hazard ratio (HR) was found for overall survival (OS), disease free survival (DFS) and recurrence-free survival (RFS) in EC. Subgroup analyses for OS were also performed to confirm the prognostic value of plasma fibrinogen. Additionally, the overall results indicated that elevated plasma fibrinogen was significantly associated with tumor invasion, lymph node metastasis (LNM) and clinical stage. Materials and Methods: A comprehensive literature retrieval was performed in PubMed, Embase, Cochrane database, Web of science and Chinese National Knowledge Infrastructure (CNKI) and Wanfang databases to identify relevant studies published prior to April 15, 2017. Conclusions: Elevated plasma fibrinogen could be served as a promising biomarker for predicting a poor prognosis and unfavorable clinicopathologic features for EC. PMID- 29190976 TI - Celastrol induces apoptosis in hepatocellular carcinoma cells via targeting ER stress/UPR. AB - Hepatocellular carcinoma (HCC) is one of the most serious and deadly diseases worldwide with limited options for effective treatment. Biomarker-based active compound targeting therapy may shed some light on novel drugs for HCC. The endoplasmic reticulum (ER) stress and unfolded protein response (UPR) play important roles in the regulation of cell fate and have become novel signaling targets for the development of anticancer drugs. Celastrol, a triterpene from traditional Chinese medicine, has been reported to possess anti-tumor effects on various cancers. We, along with several other research groups, have recently reported that UPR was induced by celastrol in several different cancers, including hepatocellular carcinoma. However, UPR status in HCC still remains unclear. The role of ER stress and autophagy in response to celastrol also has yet to be elucidated. Our results demonstrated that celastrol could cause G2/M phase rest and inhibit proliferation in HepG2 and Bel7402. Exposure to celastrol resulted in the activation of the intrinsic apoptotic pathway, via ER stress and the UPR. In murine syngeneic model studies celastrol inhibited H22 tumor growth via the induction of ER stress and apoptosis. Our study suggests that celastrol is a potential drug for HCC therapy via targeting ER-stress/UPR. PMID- 29190977 TI - PPAR-alpha acutely inhibits functional activity of ASICs in rat dorsal root ganglion neurons. AB - Peroxisome proliferator-activated receptor-alpha (PPAR-alpha), a lipid activated transcription factor of nuclear hormone receptor superfamily, can relieve pain through a rapid-response mechanism. However, little is known about the underlying mechanism. Herein, we report that PPAR-alpha activation acutely inhibits the functional activity of acid-sensing ion channels (ASICs), key sensors for extracellular protons, in rat dorsal root ganglion (DRG) neurons. Pre-application of PPAR-alpha agonist GW7647 for 2 min decreased the amplitude of proton-gated currents mediated by ASICs in a concentration-dependent manner. GW7647 shifted the concentration-response curve for proton downwards, with a decrease of 36.9 +/ 2.3% in the maximal current response to proton. GW7647 inhibition of proton gated currents can be blocked by GW6471, a selective PPAR-alpha antagonist. Moreover, PPAR-alpha activation decreased the number of acidosis-evoked action potentials in rat DRG neurons. Finally, peripheral administration of GW7647 dose dependently relieved nociceptive responses to injection of acetic acid in rats. These results indicated that activation of peripheral PPAR-alpha acutely inhibited functional activity of ASICs in a non-genomic manner, which revealed a novel mechanism underlying rapid analgesia through peripheral PPAR-alpha. PMID- 29190978 TI - Pooling-analysis on hMLH1 polymorphisms and cancer risk: evidence based on 31,484 cancer cases and 45,494 cancer-free controls. AB - To elucidate the veritable relationship between three hMLH1 polymorphisms (rs1800734, rs1799977, rs63750447) and cancer risk, we performed this meta analysis based on overall published data up to May 2017, from PubMed, Web of knowledge, VIP, WanFang and CNKI database, and the references of the original studies or review articles. 57 publications including 31,484 cancer cases and 45,494 cancer-free controls were obtained. The quality assessment of six articles obtained a summarized score less than 6 in terms of the Newcastle-Ottawa Scale (NOS). All statistical analyses were calculated with the software STATA (Version 14.0; Stata Corp, College Station, TX). We found all the three polymorphisms can enhance overall cancer risk, especially in Asians, under different genetic comparisons. In the subgroup analysis by cancer type, we found a moderate association between rs1800734 and the risk of gastric cancer (allele model: OR = 1.14, P = 0.017; homozygote model: OR = 1.33, P = 0.019; dominant model: OR = 1.27, P = 0.024) and lung cancer in recessive model (OR = 1.27, P = 0.024). The G allele of rs1799977 polymorphism was proved to connect with susceptibility of colorectal cancer (allele model: OR = 1.21, P = 0.023; dominate model: OR = 1.32, P <0.0001) and prostate cancer (dominate model: OR = 1.36, P <0.0001). Rs63750447 showed an increased risk of colorectal cancer, endometrial cancer and gastric cancer under all genetic models. These findings provide evidence that hMLH1 polymorphisms may associate with cancer risk, especially in Asians. PMID- 29190979 TI - Resting-state functional connectivity of the dorsal frontal cortex predicts subcortical vascular cognition impairment. AB - Functional magnetic resonance imaging (fMRI) studies have revealed group differences in the frontal area between the subcortical vascular cognition impairment (SVCI) patients and the controls. However, most of the existing research focused on average differences between the two groups, and therefore had limited clinical applicability. The aim of our study was to investigate whether inter-regions functional connectivity of the dorsal frontal cortex (DFC) can be used to discriminate the SVCI from the controls at the level of the individual. Thirty-two SVCI patients and 32 demographically similar healthy individuals underwent resting-state functional magnetic resonance imaging. The DFC, derived from a prior atlas, was divided into 10 clusters. Features based on DFC were obtained through functional connectivity analysis between pairs of DFC. A nonlinear kernel support vector machine was used for classification and validated using 8-fold cross validation. An excellent classification accuracy was obtained from both the left and the right DFC functional connectivity (accuracy=75.07%, sensitivity=81.57% and specificity=61.71%; accuracy=45.38%, sensitivity=60.74% and specificity=39.48%; P<0.001). These findings shed further light on the pathogenesis of SVCI and showed promising classification performance using machine learning analysis based on DFC fMRI data, which may be useful for the differentiation of SVCI. PMID- 29190980 TI - Transplanted olfactory ensheathing cells restore retinal function in a rat model of light-induced retinal damage by inhibiting oxidative stress. AB - There is still not an effective treatment for continuous retinal light exposure and subsequent photoreceptor degeneration. Olfactory ensheathing cell (OEC) transplantation has been shown to be neuroprotective in spinal cord, and optic nerve injury and retinitis pigmentosa. However, whether OECs protect rat photoreceptors against light-induced damage and how this may work is unclear. Thus, to elucidate this mechanism, purified rat OECs were grafted into the subretinal space of a Long-Evans rat model with light-induced photoreceptor damage. Light exposure decreased a- and b- wave amplitudes and outer nuclear layer (ONL) thickness, whereas the ONL of rats exposed to light for 24 h after having received OEC transplants in their subretinal space was thicker than the PBS control and untreated groups. A- and b- wave amplitudes from electroretinogram of OEC-transplanted rats were maintained until 8 weeks post OEC transplantation. Also, transplanted OECs inhibited formation of reactive oxygen species in retinas exposed to light. In vitro experiments showed that OECs had more total antioxidant capacity in a co-cultured 661W photoreceptor cell line, and cells were protected from damage induced by hydrogen-peroxide. Thus, transplanted OECs preserved retinal structure and function in a rat model of light-induced degeneration by suppressing retinal oxidative stress reactions. PMID- 29190981 TI - A20 enhances the radiosensitivity of hepatocellular carcinoma cells to 60Co-gamma ionizing radiation. AB - The radioresistance of hepatocellular carcinoma (HCC) cells is a critical obstacle for effectively applying radiotherapy (RT) in HCC treatment. NF-kappaB, an important transcription factor, can influence critical cell fate decisions by promoting cell survival or anti-apoptosis in response to cell-stress, e.g. chemotherapies or ionizing radiation (IR). A20, also named as tumor necrosis factor alpha induced protein 3 (TNFAIP3), is a dominant negative regulator of NF kappaB pathway and its functions in HCC are largely unknown. The present work aimed to reveal the role of A20 plays in affecting the radiosensitivity of HCC cells. Higher expression of A20 was detected in hepatic non-tumor cell line or clinical specimens compared with HCC cell lines or clinical specimens. A20 decreased the expression of proteins mediating cellular stress/injury response or epithelial-mesenchymal transition (EMT) process. Overexpression of A20 via adenovirus enhanced the effect of 60Co-gamma ionizing radiation (IR) on HCC cells' injury, e.g. G2/M arrest or DNA double strands break (DSB). Moreover, A20 also enhanced the in vitro or in vivo survival inhibiting of HCC cells induced by IR. These results reveal the roles of A20 in HCC radiosensitization and overexpression of A20 would be a novel strategy for HCC radiotherapy. PMID- 29190984 TI - Prognostic value of smoking status in non-small-cell lung cancer patients treated with immune checkpoint inhibitors: a meta-analysis. AB - Immune checkpoint inhibitors (ICIs) have emerged as a new treatment option for patients with advanced non-small-cell lung cancer (NSCLC). Some studies with ICIs in NSCLC suggested that smoking history was associated with improved survival outcomes. We conducted this meta-analysis to investigate if survival benefits of ICIs in patients with advanced NSCLC are different according to smoking status. Electronic databases were searched for eligible studies. We included randomized controlled trials with the data of survival outcomes and extracted progression free survival (PFS) or overall survival (OS) stratified by smoking status. From 6 studies, 2,389 ever-smokers and 413 never-smokers were included in the meta analysis. In first-line treatment setting, ICIs tended to improve PFS in patients with smoking history (HR = 0.85 [95% CI, 0.71-1.10], P = 0.07). For never-smokers with advanced NSCLC, chemotherapy, not ICIs, was significantly associated with improvement of PFS (HR = 2.30 [95% CI, 1.23-4.28], P = 0.009). In more than second-line setting, ICIs significantly prolonged OS over that with chemotherapy in ever-smokers (HR = 0.70 [95% CI, 0.63-0.79], P < 0.00001). For never-smokers with NSCLC, however, ICIs failed to significantly improve OS (HR = 0.79 [95% CI, 0.59-1.06], P = 0.12). In conclusion, this meta-analysis indicates that ICIs can prolong survival over that with chemotherapy in ever-smokers with advanced NSCLC. However, ICIs failed to improve survival in never-smokers. These results suggest that smoking status may be a predictive marker for survival benefits to ICIs. PMID- 29190983 TI - Ginkgetin induces autophagic cell death through p62/SQSTM1-mediated autolysosome formation and redox setting in non-small cell lung cancer. AB - Promoting cell death by autophagy could be a novel treatment for cancer. The major player in autophagy, p62, serves as a good therapeutic target. Ginkgetin, a biflavonoid from Ginkgo biloba leaves, exhibited promising anticancer activity in non-small cell lung cancer cell lines, with an IC50 lower than that of cisplatin. This anticancer effect of ginkgetin was illustrated in a xenograft nude mouse model. Ginkgetin induced autophagic cell death in A549 cells, and this effect was markedly reversed by chemical and genetic approaches. Ginkgetin showed potential binding affinity to p62. Upregulation of p62 through chemical and genetic means decreased cell death, lysosome acidification, and autophagosome formation, which consequently disrupted autolysosome formation. In addition, the decreased autophagy induced by p62 overexpression increased Nrf2/ARE activity and the oxygen consumption rate and decreased on formation of reactive oxygen species. These phenomena were exhibited in a reciprocal manner when p62 was knocked down. Thus, p62 may be a potential target in ginkgetin-induced autophagic cell death, and ginkgetin could be developed as a novel anticancer drug. PMID- 29190982 TI - Diagnostic performance enhancement of pancreatic cancer using proteomic multimarker panel. AB - Due to its high mortality rate and asymptomatic nature, early detection rates of pancreatic ductal adenocarcinoma (PDAC) remain poor. We measured 1000 biomarker candidates in 134 clinical plasma samples by multiple reaction monitoring-mass spectrometry (MRM-MS). Differentially abundant proteins were assembled into a multimarker panel from a training set (n=684) and validated in independent set (n=318) from five centers. The level of panel proteins was also confirmed by immunoassays. The panel including leucine-rich alpha-2 glycoprotein (LRG1), transthyretin (TTR), and CA19-9 had a sensitivity of 82.5% and a specificity of 92.1%. The triple-marker panel exceeded the diagnostic performance of CA19-9 by more than 10% (AUCCA19-9 = 0.826, AUCpanel= 0.931, P < 0.01) in all PDAC samples and by more than 30% (AUCCA19-9 = 0.520, AUCpanel = 0.830, P < 0.001) in patients with normal range of CA19-9 (<37U/mL). Further, it differentiated PDAC from benign pancreatic disease (AUCCA19-9 = 0.812, AUCpanel = 0.892, P < 0.01) and other cancers (AUCCA19-9 = 0.796, AUCpanel = 0.899, P < 0.001). Overall, the multimarker panel that we have developed and validated in large-scale samples by MRM-MS and immunoassay has clinical applicability in the early detection of PDAC. PMID- 29190985 TI - Prognostic value of B7-H3 expression in patients with solid tumors: a meta analysis. AB - Increasing evidence suggests B7-H3 is aberrantly expressed in various cancers, though its prognostic significance in solid tumors remains controversial. We therefore performed a meta-analysis to clarify the prognostic value of B7-H3 expression in human solid tumors. The PubMed and Embase databases were searched, and 28 studies involving 4623 patients were ultimately included in the analysis. Hazard ratios (HRs) with 95% confidence intervals (CIs) were utilized as effect estimates to evaluate the association between B7-H3 expression and overall survival (OS), progression-free survival (PFS) and recurrence-free survival (RFS). The pooled results showed B7-H3 was associated with poor OS (HR = 1.58; 95% CI: 1.32-1.90; P < 0.00001) and PFS (HR = 1.67; 95% CI: 1.05-2.65; P = 0.031), but not RFS (HR = 1.17; 95% CI: 0.89-1.53; P = 0.267). These results suggest B7-H3 is a negative predictor of OS and PFS in patients with solid tumors. B7-H3 may thus be a useful prognostic biomarker and therapeutic target for human solid tumors. However, further studies will be needed to more precisely determine the prognostic value of B7 H3 expression. PMID- 29190986 TI - The relationship between obstructive sleep apnea and obesity hypoventilation syndrome: a systematic review and meta-analysis. AB - Obstructive Sleep Apnea and Obesity Hypoventilation Syndrome are two similar diseases. Obstructive Sleep Apnea has been receiving more and more attention while the diagnostic rate of Obesity Hypoventilation Syndrome is not high. Few studies directly evaluated the relationship between them. We systematically analyzed the relevance of the two diseases. MEDLINE(r), EMBASE(r) and the Cochrane Library were carried out to find studies until May 2017. Pooled mean difference and 95% confidence interval were calculated to evaluate the value of clinical and physiologic variables in the prediction of Obesity Hypoventilation Syndrome. 9 Studies (n = 2085) fulfilled the predefined selection criteria. Totally 575 patients (28%) with Obesity Hypoventilation Syndrome were diagnosed from 2085 Obstructive Sleep Apnea patients. Among clearly diagnosed Obstructive Sleep Apnea patients, higher Body Mass Index levels(mean difference:4.72 kg/m2; 95% confidence interval: 4.26 to 5.17; p < 0.00001), higher Apnea-Hypopnea Index (mean difference: 8.36; 95% confidence interval: -3.88 to -2.84; p < 0.00001), greater neck circumference (mean difference:1.01; 95% confidence interval: 0.10 to 1.92; p = 0.03) and lower percent predicted FEV1 (mean difference:-10.28; 95% confidence interval:-11.33 to -9.22; p < 0.00001)were associated with the occurrence with obesity hypoventilation syndrome. We should be highly skeptical of obesity hypoventilation syndrome in Obstructive Sleep Apnea patients with these factors as early identification and appropriate treatment can improve prognosis. PMID- 29190987 TI - Efficacy of anti-VEGF agents in the treatment of elderly hepatocellular carcinoma: a systematic review. AB - Purpose: We aimed to investigate the role of anti-vascular endothelial growth factor (VEGF) agents, including tyrosine-kinase inhibitors or monoclonal anti bodies, in the treatment of elderly hepatocellular carcinoma (HCC) patients. Materials and Methods: Databases from PubMed, Web of Science and abstracts presented at ASCO meeting up to March 31, 2017 were searched to identify relevant studies. The endpoints were overall survival (OS) and progression-free survival (PFS). Data were examined using age cutoffs of 65 years. Results: A total of 1,309 elderly (aged >= 65 years) HCC patients from seven trials were included for analysis. Our results demonstrated that the use of anti-VEGF agents MTAs in patients aged >= 65 years significantly improved PFS (HR 0.65, 95% CI: 0.55-0.76, p < 0.001) but not for OS (HR 0.87, 95% CI: 0.73-1.05, p = 0.15). Sub-group analysis according to treatment line showed that the use of anti-VEGF agents as second-line treatment significantly improved PFS (HR 0.55, 95% CI: 0.45-0.67, p < 0.001) and marginally improved OS (HR 0.83, 95% CI: 0.68-1.01, p = 0.061). Additionally, no survival benefits were observed in elderly HCC received first line anti-VEGF treatments in terms of PFS (HR 0.87, 95% CI: 0.67-1.13, p = 0.29) and OS (HR 1.19, 95% CI: 0.74-1.36, p = 0.47). No publication bias was detected by Begg's and Egger's tests for OS. Conclusions: The findings of this study show that elderly HCC patients who relapsed after a first-line sorafenib treatment obtains a survival benefits from anti-VEGF agents rechallenge. Further studies are recommended to search for predictors of good responders in these patients received anti-VEGF agents. PMID- 29190988 TI - Association of Ezrin expression with the progression and prognosis of gastrointestinal cancer: a meta-analysis. AB - Background: Ezrin, a cytoskeletal protein, is involved in cell adhesion. Several studies have been performed to explore the association between Ezrin and gastrointestinal cancers, but the results are inconclusive. This meta-analysis aims to assess the prognostic value of Ezrin. Materials and Methods/Findings: PubMed and EMBASE were searched. Pooled hazard ratio (HR), odds ratio (OR) and 95% confidence intervals (CI) were utilized to evaluate the association between Ezrin expression and various clinical parameters. 2701 patients from 19 studies were included in the meta-analysis. For gastric cancer, Ezrin expression was associated with tumor grade (OR 2.32, 95% CI 1.53-3.52), TNM stage (OR 4.69, 95% CI 1.38-15.89), lymph node involvement (OR 3.96, 95% CI 1.47-10.70) and overall survival (HR 1.88, 95% CI 1.33-2.66). In colorectal cancer, Ezrin expression was associated with tumor grade (OR 3.94, 95% CI 2.10-3.78), TNM stage (OR 5.66, 95% CI 1.41-22.67), lymph node metastasis (OR 9.52, 95% CI 3.93-23.02), distant metastasis (OR 3.06, 95% CI 1.77-5.31), disease free survival (HR 2.48, 95% CI 1.44-4.28). For esophageal cancer, Ezrin expression was associated with lymph node metastasis (OR 2.07, 95% CI 1.00-4.28) and overall survival (HR 1.49, 95% CI 1.17-1.89). Conclusions: Ezrin expression is significantly associated with tumor grade, TNM stage, and lymph node metastasis in gastric and colorectal cancers. For gastric cancers, Ezrin is useful in predicting distant metastasis. Survival data showed that high Ezrin expression is associated with poor prognosis in gastric, colorectal and esophageal cancers. Our findings suggest that Ezrin might be a potential biomarker in several gastrointestinal cancers. PMID- 29190989 TI - Aberrant pattern of regional cerebral blood flow in Alzheimer's disease: a voxel wise meta-analysis of arterial spin labeling MR imaging studies. AB - Many studies have applied arterial spin labeling (ASL) to characterize cerebral perfusion patterns of Alzheimer's disease (AD). However, findings across studies are not conclusive. A quantitatively voxel-wise meta-analysis to pool the resting state ASL studies that measure regional cerebral blood flow (rCBF) alterations in AD was conducted to identify the most consistent and replicable perfusion pattern using seed-based d mapping. The meta-analysis, including 17 ASL studies encompassing 327 AD patients and 357 healthy controls, demonstrated that decreased rCBF in AD patients relative to healthy controls were consistently identified in the bilateral posterior cingulate cortices (PCC)/precuneus, bilateral inferior parietal lobules (IPLs), and left dorsolateral prefrontal cortex. The meta-regression analysis showed that more severe cognitive impairment in the AD samples correlated with greater decreases of rCBF in the bilateral PCC and left IPL. This study characterizes an aberrant ASL-rCBF perfusion pattern of AD involving the posterior default mode network and executive network, which are implicated in its pathophysiology and hold promise for developing imaging biomarkers. PMID- 29190990 TI - Smoking and the risk of diabetic nephropathy in patients with type 1 and type 2 diabetes: a meta-analysis of observational studies. AB - Background: Conflicting evidence exists for observational studies on whether tobacco smoking is a risk factor for diabetic nephropathy (DN) in patients with type 1 (T1DM) and type 2 diabetes mellitus (T2DM). In this meta-analysis, we aimed to assess the effects of tobacco smoking on the development of DN. Materials and Methods: We searched MEDLINE and EMBASE databases from their inception to March 31st, 2017 for cross-sectional, case-control, and prospective cohort studies. We screened reference lists of retrieved articles. Summary relative risks (SRRs) and 95% confidence intervals (CIs) were calculated using a random-effects model. Results: A total of nineteen observational studies (1 case control, 8 cross-sectional and 10 prospective cohort studies) were identified, involving more than 78,000 participants and a total of 17,832 DN cases. Compared with never-smokers, there was an augmented SRR (95% CI) of DN in ever-smokers in patients with T1DM (1.31 [1.06-1.62]; P = 0.006) and T2DM (1.44 [1.24-1.67]; P < 0.001), respectively. In patients with T1DM, the SRR (95% CI) was 1.25 (0.86 1.83) for microalbuminuria only, 1.27 (1.10-1.48) for macroalbuminuria only, and 1.06 (0.97-1.15) for end-stage renal disease (ESRD). In patients with T2DM, the SRR (95% CI) associated with ever smoking was 1.46 (0.94-2.26) for microalbuminuria only, 1.72 (1.04-2.84) for macroalbuminuria only, and 1.10 (0.36 3.33) for ESRD. Conclusions: Our meta-analysis suggests evidence for cigarette smoking as an independent risk factor for the development of DN in patients with both T1DM and T2DM. PMID- 29190991 TI - Association of HLA-DRB1 polymorphism with Alzheimer's disease: a replication and meta-analysis. AB - Genome-wide association studies (GWAS) have identified one single-nucleotide polymorphism (SNP) rs9271192 within HLA-DRB1 as a risk factor for Alzheimer's disease (AD) in Caucasians. The effect of rs9271192 on AD needed to be verified in other ethnic cohorts. In order to evaluate the association between HLA-DRB1 rs9271192 polymorphism and late-onset AD (LOAD) in the Northern Han Chinese population, we recruited 982 LOAD patients and 1344 sex- and age-matched healthy controls. The results showed that HLA-DRB1 rs9271192 was associated with LOAD (genotype P = 0.015, allele P = 0.04). The results of logistic regression revealed the C allele homozygosity strongly increased the risk of LOAD under a recessive model in the total sample (P = 0.004, OR =2.069, 95% CI = 1.262-3.434). When these data were stratified by apolipoprotein E (APOE) epsilon4 status, the observed association was confined to APOE epsilon4 non-carriers (additive model: P=0.048, OR =1.191, 95% CI =1.001-1.417; recessive model: P < 0.001, OR = 2.601, 95% CI =1.519-4.566). Furthermore, meta-analysis after sensitive analysis confirmed that rs9271192 within HLA-DRB1 increased the risk of LOAD (OR = 1.12, 95% CI = 1.08-1.15). To summarize, the C allele in HLA-DRB1 rs9271192 may be an independent risk factor for LOAD. PMID- 29190992 TI - Prognostic role of long non-coding RNA LINC00152 in Chinese cancer patients: a meta-analysis. AB - The role of long intergenic non-coding RNA 152 (LINC00152) in predicting the prognosis of cancer has been investigated but results remain inconclusive and inconsistent. A meta-analysis was performed to explore the effect of LINC00152 on cancer prognosis. PubMed and ScienceDirect were searched for suitable studies and the results of 10 studies with a total of 775 patients were pooled. Pooled hazard ratios (HRs) and odds ratios (ORs) were calculated to assess the prognostic value of LINC00152. The results revealed that tumour patients with high LINC00152 expression were more likely to have lymph node metastasis (OR = 2.94, 95% CI 1.97 4.40, P < 0.001) and unfavourable tumour-node-metastasis stage (grade III/IV vs. I/II: OR = 3.07, 95% CI 1.69-5.59, P < 0.001). In addition, high LINC00152 expression levels were significantly associated with poor overall survival (pooled HR = 1.99, 95% CI 1.54-2.56, P < 0.001). The results suggest that high LINC00152 expression may serve as a predictive biomarker for the poor prognosis of various cancers in the Chinese population. PMID- 29190993 TI - Whether partial colectomy is oncologically safe for patients with transverse colon cancer: a large population-based study. AB - Due to special tumor location and technical difficulty of transverse colon cancer (TCC), partial colectomy (PC) is being widely applied in selected TCC patients, instead of extended hemicolectomy (HC). However, the oncological safety of this less aggressive surgical approach is not well studied. Here, we identified 10344 TCC patients from Surveillance, Epidemiology, and End-Results (SEER) database. The surgical treatment for those patients included PC and HC. Firstly, we compared lymph nodes evaluations between patients treated with HC and PC, including median number of nodes, the rate of nodes >= 12 and the rate of node positivity. Then, 5-year cancer specific survival (CSS) was obtained. Kaplan Meier methods and Cox regression models were performed to assess the correlations between prognostic factors and long-term survival. Despite of less node examined by PC, the rate of node positivity was equal between PC and HC, suggesting node retrieval under PC was adequate to tumor stage. In addition, the 5-year CSS for patients who underwent PC were 67.5%, which was similar to patients who received HC (66.5%). The result after propensity score matching also confirmed the equivalent survival outcome between HC and PC. However, subgroup analyses showed that patients with tumor size >= 5 cm could not obtain survival benefit from PC. Furthermore, surgical approach was not considered as independent prognostic factor for TCC patients. Therefore, although PC is a less aggressive surgical approach, it should be a safe and feasible option for selected TCC patients. PMID- 29190994 TI - Hemorrhage of brain metastasis is a poor prognostic factor in hepatocellular carcinoma patients. AB - It is unclear whether hemorrhage of brain metastasis is a poor prognostic factor in patients with hepatocellular carcinoma. We conducted a retrospective cohort study to compare overall survival between hemorrhage and no-hemorrhage groups of hepatocellular carcinoma patients with brain metastasis. Hepatocellular carcinoma patients with brain metastasis treated between June 2000 and June 2016 at the Cancer Hospital of Guangxi Medical University were retrospectively reviewed. Clinical characteristics and overall survival were compared between patients with (n = 11) and without (n = 25) hemorrhage of brain metastasis. Univariate and multivariate survival analyses showed hemorrhage to be a poor prognostic factor (hazard ratio = 5.812, 95% confidence interval: 1.399-24.142, p = 0.015). Patients with hemorrhage had a shorter median survival than those without hemorrhage (4 weeks vs 8 weeks, p = 0.001). These results suggest hemorrhage of brain metastasis is a poor prognostic factor in patients with hepatocellular carcinoma patients. PMID- 29190995 TI - Predictors of hypertension urgency in primary aldosteronism patients during the first 24 hours after surgery. AB - Study about blood pressure variation in the first 24 hours post-operation is limited in patients with adrenal aldosterone-producing adenoma. We aim to evaluate the potential predictors for postoperative hypertension urgency during the first 24 hours after laparoscopic adrenalectomy in patients with aldosterone producing adenoma. Clinical data of 177 patients with aldosterone-producing adenoma were retrospectively collected from January 2009 to December 2015 and the potential factors that may influence postoperative blood pressure during the first 24 hours after surgery were analyzed. The factors included gender, age, body mass index, preoperative maximum systolic blood pressure, number of antihypertensive medicines, preoperative spironolactone treatment, duration of hypertension, surgical method and approach, adenoma diameter, preoperative proteinuria, estimated glomerular filtration rate, serum potassium and serum aldosterone. Univariate and multivariate regression analyses were used to evaluate the relationship between the above variables and postoperative hypertension urgency. We found that the proportion of patients with a higher systolic blood pressure >= 160 mmHg and >= 180 mmHg were significantly increased post-operation (both p < 0.001). In multivariate analysis, the maximum systolic blood pressure was an independent predictor of postoperative hypertension urgency, and the cut-off point was 157 mmHg with the sensitivity of 66% and specificity of 82%. Multivariable analysis also showed that preoperative maximum systolic blood pressure and number of antihypertensive medicines were independent risk factors for higher postoperative systolic blood pressure. This study was derived from a high volume adrenal tumor center, and these data may provide a potential tool to guide preoperative counseling. PMID- 29190996 TI - Surgical resection for hepatocellular carcinoma with portal vein tumor thrombus in the Asia-Pacific region beyond the Barcelona Clinic Liver Cancer treatment algorithms: a review and update. AB - Portal vein tumor thrombus (PVTT) usually worsens prognosis of hepatocellular carcinoma (HCC), as characterized by aggressive disease progression, impaired liver function and tolerance to treatment. Conventionally, the European Association for the Study of the Liver (EASL) and the American Association for the Study of Liver Diseases (AASLD) accepted the Barcelona Clinical Liver Cancer (BCLC) treatment algorithms, identifying PVTT as an absolute contra-indication of surgical resection for HCC. HCC-PVTT patients are offered sorafenib as the standard treatment. Evidently, SHARP and Asia-Pacific trials demonstrated that sorafenib only improves overall survival by approximately 3 months in patients with advanced HCC. Besides, BCLC treatment algorithm does not provide different therapeutic recommendations for different degree of PVTT, and only supports single treatment option for each stage of HCC rather than a combination of comprehensive treatments, which limited individual and best care for every HCC PVTT patients. In the past few years, many surgeons do not restrict surgical resection to HCC with PVTT. There have been new reports demonstrated that surgical treatment is feasible for selected HCC-PVTT patients with resectable tumor and moderate liver function to prolong survival period and elevate life quality as long as PVTT limited to the first-order branch, whereas non-surgical treatments fail to provide comparable therapeutic effects. At present, guidelines on HCC management from mainland China, Japan, and Hong Kong have been updated and a consensus of Asia-Pacific experts has established that portal venous invasion is not an absolute contradiction of surgical resection for HCC. This review summarized the emerging data on surgical resection for HCC-PVTT patients beyond the BCLC treatment algorithms and discussed recent therapeutic conceptualchanges in the Asia-Pacific region. PMID- 29190998 TI - Radiological and nuclear medicine imaging of sarcoidosis. AB - Sarcoidosis is a multisystem chronic inflammatory disease of unknown etiology characterized by widespread growth of non-caseating granulomas. The diagnosis of sarcoidosis is based on clinical and imaging presentation, histologic confirmation and the absence of alternative diseases. Radiology and Nuclear Medicine play an essential role in the diagnostic work-up of patients with sarcoidosis to assess disease extent and activity. In addition, imaging modalities have shown their potential in managing these patients in terms of treatment response and prognostic assessment. Sarcoidosis has a predilection for chest involvement, showing typical and atypical manifestations in the lungs, airways and hilar/mediastinal lymph nodes. Chest radiography (X-ray) still plays an important role in suggesting diagnosis for cases with typical presentation of sarcoidosis, while computed tomography (CT) has higher accuracy in detecting early stage disease and in narrowing differential diagnosis, particularly in atypical manifestations. For extrathoracic involvement, both CT and MR (magnetic resonance) have comparable performance even though MR is the modality of choice for assessing neurosarcoidosis and cardiac sarcoidosis. In the last decades positron emission tomography/CT (PET/CT) has demonstrated an increasing and relevant value in assessing disease extent and activity, treatment planning and therapy response, with a crucial role in the management of cardiac sarcoidosis. In this article, an overview of the possible imaging manifestations of thoracic and extrathoracic sarcoidosis and current concepts on staging, response assessment and prognosis is provided. Finally, the potential applications of non FDG radiotracers is briefly discussed. PMID- 29190999 TI - Animal models for the study of inflammatory bowel diseases: a meta-analysis on modalities for imaging inflammatory lesions. AB - Inflammatory bowel diseases are lifelong disorders affecting the gastrointestinal tract characterized by intermittent disease flares and periods of remission with a progressive and destructive nature. Unfortunately, the exact etiology is still not completely known, therefore a causal therapy to cure the disease is not yet available. Current treatment options mainly encompass the use of non-specific anti-inflammatory agents and immunosuppressive drugs that cause significant side effects that often have a negative impact on patients' quality of life. As the majority of patients need a long-term follow-up it would be ideal to rely on a non-invasive technique with good compliance. Currently, the gold standard diagnostic tools for managing IBD are represented by invasive procedures such as colonoscopy and histopathology. Nevertheless, recent advances in imaging technology continue to improve the ability of imaging techniques to non invasively monitor disease activity and treatment response in preclinical models of IBD. Novel and emerging imaging techniques not only allow direct visualization of intestinal inflammation, but also enable molecular imaging and targeting of specific alterations of the inflamed murine mucosa. Furthermore, molecular imaging advances allow us to increase our knowledge on the critical biological pathways involved in disease progression by characterizing in vivo processes at a cellular and molecular level and enabling significant improvements in the understanding of the etiology of IBD. This review presents a critical and updated overview on the imaging advances in animal models of IBD. Our aim is to highlight the potential beneficial impact and the range of applications that imaging techniques could offer for the improvement of the clinical monitoring and management of IBD patients: diagnosis, staging, determination of therapeutic targets, monitoring therapy and evaluation of the prognosis, personalized therapeutic approaches. PMID- 29191000 TI - In-vivo imaging of tumor-infiltrating immune cells: implications for cancer immunotherapy. AB - Dynamic interactions between tumor cells and immune cells promote the initiation, progression, metastasis and therapy-resistance of cancer. With respect to immunotherapy, immune cell populations such as cytotoxic CD8+ T-cells, CD56+ NK cells and myeloid phagocytic cells play decisive roles. From an imaging perspective, the immune system displays unique challenges, which have implications for the design and performance of studies. The immune system comprises highly mobile cells that undergo distinct phases of development and activation. These cells circulate through several compartments during their active life span and accumulate in rather limited numbers in cancer lesion, where their effector phenotype further diversifies. Given these features, accurate evaluation of the tumor microenvironment and its cellular components during anti cancer immunotherapy is challenging. In-vivo imaging currently offers quantitative and sensitive modalities that exploit long-lived tracers to interrogate, e.g. distinct immune cell populations, metabolic phenotypes, specific targets relevant for therapy or critical for their effector function. This review provides a comprehensive overview of current status for in-vivo imaging tumor-infiltrating immune cell populations, focusing on lymphocytes, NK cells and myeloid phagocytic cells, with emphasis on clinical translation. PMID- 29190997 TI - Inflammatory microenvironment in the initiation and progression of bladder cancer. AB - Accumulating evidence suggests the idea that chronic inflammation may play a critical role in various malignancies including bladder cancer and long-term treatment with non-steroidal anti-inflammatory drugs (NSAIDs) is significantly effective in reducing certain cancer incidence and mortality. However, the molecular mechanisms leading to malignant transformation and the progression of bladder cancer in a chronically inflammatory environment remain largely unknown. In this review, we will describe the role of inflammation in the formation and development of bladder cancer and summarize the possible molecular mechanisms by which chronic inflammation regulates cell immune response, proliferation and metastasis. Understanding the novel function orchestrating inflammation and bladder cancer will hopefully provide us insights into their future clinical significance in preventing bladder carcinogenesis and progression. PMID- 29191001 TI - Hybrid imaging in Crohn's disease: from SPECT/CT to PET/MR and new image interpretation criteria. AB - Crohn's disease is a chronic relapsing disease characterized by mucosal inflammation, lymphocytes infiltration and fibrotic strictures. Usually, the assessment of location, extension, inflammatory activity and severity of intestinal lesions is complex and invasive with endoscopic methods or histological and biochemical investigations. Thus, the diagnosis remains a challenge for the management of patients. Nuclear medicine techniques, in particular hybrid and molecular imaging, might offer a valid option for the evaluation and determination of the prognosis of the disease. Indeed, imaging methods provide a non-invasive, reproducible and quantitative analysis. An overview of the currently available multimodality imaging techniques in Crohn's disease are reviewed, with particular regard to positron-emission tomography/magnetic resonance and the choice of the best evaluation Score, explaining advantages and disadvantages of each one, with particular regard to their potential role for the assessment of disease activity and extent of inflammation in order to improve the diagnosis. We propose new interpretation criteria for PET/MR images. PMID- 29191002 TI - Tailoring Natural Abenquines To Inhibit the Photosynthetic Electron Transport through Interaction with the D1 Protein in Photosystem II. AB - Abenquines are natural N-acetylaminobenzoquinones bearing amino acid residues, which act as weak inhibitors of the photosynthetic electron transport chain. Aiming to exploit the abenquine scaffold as a model for the synthesis of new herbicides targeting photosynthesis, 14 new analogues were prepared by replacing the amino acid residue with benzylamines and the acetyl with different acyl groups. The synthesis was accomplished in three steps with a 68-95% overall yield from readily available 2,5-dimethoxyaniline, acyl chlorides, and benzyl amines. Key steps include (i) acylation of the aniline, (ii) oxidation, and (iii) oxidative addition of the benzylamino moiety. The compounds were assayed for their activity as Hill inhibitors, under basal, uncoupled, or phosphorylating conditions, or excluding photosystem I. Four analogues showed high effectiveness (IC50 = 0.1-0.4 MUM), comparable with the commercial herbicide diuron (IC50 = 0.3 MUM). The data suggest that this class of compounds interfere at the reducing side of photosystem II, having protein D1 as the most probable target. Molecular docking studies with the plastoquinone binding site of Spinacia oleracea further strengthened this proposal. PMID- 29191003 TI - Enhanced Gas Separation through Nanoconfined Ionic Liquid in Laminated MoS2 Membrane. AB - Two-dimensional (2D) materials-based membranes show great potential for gas separation. Herein an ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]), was confined in the 2D channels of MoS2-laminated membranes via an infiltration process. Compared with the corresponding bulk [BMIM][BF4], nanoconfined [BMIM][BF4] shows an obvious incremental increase in freezing point and a shift of vibration bands. The resulting MoS2-supported ionic liquid membrane (MoS2 SILM) exhibits excellent CO2 separation performance with high CO2 permeance (47.88 GPU) and superb selectivity for CO2/N2 (131.42), CO2/CH4 (43.52), and CO2/H2 (14.95), which is much better than that of neat [BMIM][BF4] and [BMIM][BF4]-based membranes. The outstanding performance of MoS2 SILMs is attributed to the nanoconfined [BMIM][BF4], which enables fast transport of CO2. Long-term operation also reveals the durability and stability of the prepared MoS2 SILMs. The method of confining ILs in the 2D nanochannels of 2D materials may pave a new way for CO2 capture and separation. PMID- 29191004 TI - Wrinkle-Free Single-Crystal Graphene Wafer Grown on Strain-Engineered Substrates. AB - Wrinkles are ubiquitous for graphene films grown on various substrates by chemical vapor deposition at high temperature due to the strain induced by thermal mismatch between the graphene and substrates, which greatly degrades the extraordinary properties of graphene. Here we show that the wrinkle formation of graphene grown on Cu substrates is strongly dependent on the crystallographic orientations. Wrinkle-free single-crystal graphene was grown on a wafer-scale twin-boundary-free single-crystal Cu(111) thin film fabricated on sapphire substrate through strain engineering. The wrinkle-free feature of graphene originated from the relatively small thermal expansion of the Cu(111) thin film substrate and the relatively strong interfacial coupling between Cu(111) and graphene, based on the strain analyses as well as molecular dynamics simulations. Moreover, we demonstrated the transfer of an ultraflat graphene film onto target substrates from the reusable single-crystal Cu(111)/sapphire growth substrate. The wrinkle-free graphene shows enhanced electrical mobility compared to graphene with wrinkles. PMID- 29191005 TI - Construction of High Drug Loading and Enzymatic Degradable Multilayer Films for Self-Defense Drug Release and Long-Term Biofilm Inhibition. AB - Bacterial infections and biofilm formation on the surface of implants are important issues that greatly affect biomedical applications and even cause device failure. Construction of high drug loading systems on the surface and control of drug release on-demand is an efficient way to lower the development of resistant bacteria and biofilm formation. In the present study, (montmorillonite/hyaluronic acid-gentamicin)10 ((MMT/HA-GS)10) organic/inorganic hybrid multilayer films were alternately self-assembled on substrates. The loading dosage of GS was as high as 0.85 mg/cm2, which could be due the high specific surface area of MMT. The obtained multilayer film with high roughness gradually degraded in hyaluronidase (HAS) solutions or a bacterial infection microenvironment, which caused the responsive release of GS. The release of GS showed dual enzyme and bacterial infection responsiveness, which also indicated good drug retention and on-demand self-defense release properties of the multilayer films. Moreover, the GS release responsiveness to E. coli showed higher sensitivity than that to S. aureus. There was only ~5 wt % GS release from the film in PBS after 48 h of immersion, and the amount quickly increased to 30 wt % in 105 CFU/mL of E. coli. Importantly, the high drug dosage, smart drug release, and film peeling from the surface contributed to the efficient antibacterial properties and long-term biofilm inhibition functions. Both in vitro and in vivo antibacterial tests indicated efficient sterilization function and good mammalian cell and tissue compatibility.

AB - Nanoparticle (NP)-mediated drug delivery (NMDD) has emerged as a novel method to overcome the limitations of traditional systemic delivery of therapeutics, including the controlled release of the NP-associated drug cargo. Currently, our most advanced understanding of how to control NP-associated cargos is in the context of soft nanoparticles (e.g., liposomes), but less is known about controlling the release of cargos from the surface of hard NPs (e.g., gold NPs). Here we employ a semiconductor quantum dot (QD) as a prototypical hard NP platform and use intracellularly triggered actuation to achieve spatiotemporal control of drug release and modulation of drug efficacy. Conjugated to the QD are two peptides: (1) a cell-penetrating peptide (CPP) that facilitates uptake of the conjugate into the endocytic pathway and (2) a display peptide conjugated to doxorubicin (DOX) via three different linkages (ester, disulfide, and hydrazone) that are responsive to enzymatic cleavage, reducing conditions, and low pH, respectively. Formation of the QD-[peptide-DOX]-CPP complex is driven by self assembly that allows control over both the ratio of each peptide species conjugated to the QD and the eventual drug dose delivered to cells. Forster resonance energy transfer assays confirmed successful assembly of the QD-peptide complexes and functionality of the linkages. Confocal microscopy was employed to visualize residence of the QD-[peptide-DOX]-CPP complexes in the endocytic pathway, and distinct differences in DOX localization were noted for the ester linkage, which showed clear signs of nuclear delivery versus the hydrazone, disulfide, and amide control. Finally, delivery of the QD-[peptide-DOX]-CPP conjugate resulted in cytotoxicity for the ester linkage that was comparable to free DOX. Attachment of DOX via the hydrazone linkage facilitated intermediary toxicity, while the disulfide and amide control linkages showed minimal toxicity. Our data demonstrate the utility of hard NP-peptide bioconjugates to function as multifunctional scaffolds for simultaneous control over cellular drug uptake and toxicity and the vital role played by the nature of the chemical linkage that appends the drug to the NP carrier.

AB - Hydrogen peroxide (H2O2) is an endogenous molecule that plays several important roles in brain function: it is generated in cellular respiration, serves as a modulator of dopaminergic signaling, and its presence can indicate the upstream production of more aggressive reactive oxygen species (ROS). H2O2 has been implicated in several neurodegenerative diseases, including Parkinson's disease (PD), creating a critical need to identify mechanisms by which H2O2 modulates cellular processes in general and how it affects the dopaminergic nigrostriatal pathway, in particular. Furthermore, there is broad interest in selective electrochemical quantification of H2O2, because it is often enzymatically generated at biosensors as a reporter for the presence of nonelectroactive target molecules. H2O2 fluctuations can be monitored in real time using fast-scan cyclic voltammetry (FSCV) coupled with carbon-fiber microelectrodes. However, selective identification is a critical issue when working in the presence of other molecules that generate similar voltammograms, such as adenosine and histamine. We have addressed this problem by fabricating a robust, H2O2-selective electrode. 1,3-Phenylenediamine (mPD) was electrodeposited on a carbon-fiber microelectrode to create a size-exclusion membrane, rendering the electrode sensitive to H2O2 fluctuations and pH shifts but not to other commonly studied neurochemicals. The electrodes are described and characterized herein. The data demonstrate that this technology can be used to ensure the selective detection of H2O2, enabling confident characterization of the role this molecule plays in normal physiological function as well as in the progression of PD and other neuropathies involving oxidative stress.

AB - Przewalskin A, a novel C23 terpenoid with anti-HIV-1 activity from Salvia przewalskii Maxim, was formed in 10 steps via isorosmanol from (+)-carnosic acid. The synthetic strategy was inspired primarily by the biogenetic hypothesis and was enabled by epoxidation, epoxide ring opening, and lactonization in one pot to prepare the 11,12-dimethoxy isorosmanol, and bismuthonium ylide-induced ring expansion of o-quinone to construct the 2-acyl-3-hydroxytropone. PMID- 29191009 TI - Prediction of Broad-Spectrum Pathogen Attachment to Coating Materials for Biomedical Devices. AB - Bacterial infections in healthcare settings are a frequent accompaniment to both routine procedures such as catheterization and surgical site interventions. Their impact is becoming even more marked as the numbers of medical devices that are used to manage chronic health conditions and improve quality of life increases. The resistance of pathogens to multiple antibiotics is also increasing, adding an additional layer of complexity to the problems of employing safe and effective medical procedures. One approach to reducing the rate of infections associated with implanted and indwelling medical devices is the use of polymers that resist the formation of bacterial biofilms. To significantly accelerate the discovery of such materials, we show how state of the art machine learning methods can generate quantitative predictions for the attachment of multiple pathogens to a large library of polymers in a single model for the first time. Such models facilitate design of polymers with very low pathogen attachment across different bacterial species that will be candidate materials for implantable or indwelling medical devices such as urinary catheters, cochlear implants, and pacemakers. PMID- 29191010 TI - Design of a Temperature-Responsive Transcription Terminator. AB - RNA structures regulate various steps in gene expression. Transcription in bacteria is typically terminated by stable hairpin structures. Translation initiation can be modulated by metabolite- or temperature-sensitive RNA structures, called riboswitches or RNA thermometers (RNATs), respectively. RNATs control translation initiation by occlusion of the ribosome binding site at low temperatures. Increasing temperatures destabilize the RNA structure and facilitate ribosome access. In this study, we exploited temperature-responsive RNAT structures to design regulatory elements that control transcription termination instead of translation initiation in Escherichia coli. In order to mimic the structure of factor-independent intrinsic terminators, naturally occurring RNAT hairpins were genetically engineered to be followed by a U stretch. Functional temperature-responsive terminators (thermoterms) prevented mRNA synthesis at low temperatures but resumed transcription after a temperature upshift. The successful design of temperature-controlled terminators highlights the potential of RNA structures as versatile gene expression control elements. PMID- 29191011 TI - Use of Lentinan To Control Sharp Eyespot of Wheat, and the Mechanism Involved. AB - Lentinan (LNT), a complex polysaccharide with a beta-(1->3)-linked backbone of d glucose residues, has been reported to inhibit plant diseases. Our objective was to explore the efficacy and action mechanism of LNT used as a seed dressing to control sharp eyespot of wheat. Seed dressing promoted wheat growth. At control germination rates of 50%, 8 g of LNT/100 kg of seeds of the Jimai 22, Shannong 23, and Luyuan 502 cultivars significantly increased seed germination to 54%, 52%, and 51%, respectively. Seven days after emergence, the heights and root activity of wheat treated with LNT were significantly greater than those of controls. These effects were dose-dependent. At this time, the plant heights of Jimai 22, Shannong 23, and Luyuan 502 cultivars were 9.52, 8.52, and 10.52 cm, respectively, significantly higher than that of the controls. LNT prevented the development of wheat sharp eyespot. In the highly susceptible Jimai 22 cultivar, sharp eyespot development was reduced by 33.7%, 31.9%, and 30.4% at 7, 14, and 21 days after germination. LNT somewhat increased phenylalanine ammonia-lyase, peroxidase, and superoxide dismutase activity; reduced the malondialdehyde content; increased chlorophyll a and b levels; and enhanced the root vigor of wheat. These effects peaked 7 days after germination. LNT increased transcription of the genes encoding alternative oxidase (AOX) and beta-1,3-glucanase (GLU), the salicylic acid signaling pathway-related gene NbPR1a, and the sharp eyespot resistance-related gene RS33. A significant dose-effect relationship was evident in terms of AOX transcription; we thus speculate that AOX may be the target gene. PMID- 29191012 TI - Tape-Assisted Photolithographic-Free Microfluidic Chip Cell Patterning for Tumor Metastasis Study. AB - Cancer metastatic dissemination is a complex event during tumor progression which involves cell-cell and cell-matrix interactions. Micropatterning is one of the most efficient ways to study tumor development because it can tune the distribution of cells with spatial and temporal control. Extensive studies have shown that microfluidics can provide a feasible method for cell patterning. However, the current technique requires a microfabrication laboratory to manufacture the chip, which results in inaccessibility to researchers, especially biologists who focus on disclosing biological mechanisms rather than the methods. In this work, we developed a new methodology (tape-assisted photolithographic free microfluidic chip, TAPMiC) that can realize homogeneous and heterogeneous micropatterning (45 features, 300 MUm diameter of each) on a culture dish without the photolithographic procedure. We have applied this method to study critical biological problems, such as tumor cell migration under different conditions, including antitumor pharmaceutics and candidate gene RNAi assay that was relevant to tumor translocation and invasion. Moreover, this platform can achieve copatterning to recapitulate the tumor invasion scenario with single-cell trackable analysis. To decode regulation during metastasis, we conducted in situ recovering for quantitative polymerase chain reaction (qPCR) analysis from each cell type from tumor-fibroblast copairing. Regulation of several essential genes has unveiled that matrix degradation gene MMP2 and angiogenesis associated gene VEGFA were up-regulated in tumor cells in the fibroblast-enriched niche compared with homogeneous cultivation. Therefore, this approach constitutes a novel tool for investigating metastasis with quantitative measurements both on phenotype and genetical information. PMID- 29191013 TI - Multiscale Molecular Dynamics Approach to Energy Transfer in Nanomaterials. AB - After local transient fluctuations are dissipated, in an energy transfer process, a system evolves to a state where the energy density field varies slowly in time relative to the dynamics of atomic collisions and vibrations. Furthermore, the energy density field remains strongly coupled to the atomic scale processes (collisions and vibrations), and it can serve as the basis of a multiscale theory of energy transfer. Here, a method is introduced to capture the long scale energy density variations as they coevolve with the atomistic state in a way that yields insights into the basic physics and implies an efficient algorithm for energy transfer simulations. The approach is developed based on the N-atom Liouville equation and an interatomic force field and avoids the need for conjectured phenomenological equations for energy transfer and other processes. The theory is demonstrated for sodium chloride and silicon dioxide nanoparticles immersed in a water bath via molecular dynamics simulations of the energy transfer between a nanoparticle and its aqueous host fluid. The energy density field is computed for different sets of symmetric grid densities, and the multiscale theory holds when slowly varying energy densities at the nodes are obtained. Results strongly depend on grid density and nanoparticle constituent material. A nonuniform temperature distribution, larger thermal fluctuations in the nanoparticle than in the bath, and enhancement of fluctuations at the surface, which are expressed due to the atomic nature of the systems, are captured by this method rather than by phenomenological continuum energy transfer models. PMID- 29191014 TI - Pyrrolidone Modification Prevents PAMAM Dendrimers from Activation of Pro Inflammatory Signaling Pathways in Human Monocytes. AB - The biological features of dendrimers are affected by the character of highly reactive terminal moieties. In some polyamine dendrimer types the surface charge makes them bioincompatible and prevent their direct medical application. Moreover, foreign particles can induce the immune response which is undesirable due to the adverse side effects in vivo. The reduction of cytotoxicity of positively charged macromolecules is possible through chemical modifications of terminal groups. In our study, we have developed new derivatives of PAMAM dendrimers modified with 4-carbomethoxypyrrolidone and evaluated their immunomodulatory properties. The experiments were conducted on two human cancer myeloid cell lines: THP-1 and U937. To evaluate the cytotoxicity of dendrimers, the reasazurin assay was applied. The expression level of NF-kappaB targets (NFKBIA, BTG2) and cytokine genes (IL1B, TNF) was determined by quantitative real time RT-PCR. The measurement of binding of NF-kappaB to a consensus DNA probe was determined by electrophoretic mobility shift assay. The ELISA cytokine assay was performed to measure protein concentration of IL-1beta and TNFalpha. We have found that PAMAM-pyrrolidone dendrimers did not impact THP-1 and U937 viability even at high concentrations (up to 200 MUM). The surface modification prevented PAMAM dendrimers from stimulating NF-kappaB-related signal transduction, which have been determined on the level of nuclear translocation, gene expression and protein secretion. Pyrrolidone modification efficiently prevents PAMAM dendrimers from stimulating pro-inflammatory response in human cancer myeloid cell lines, thus it can be used to improve the biocompatibility of positively charged dendrimers and to broaden the scope of their biological applications. PMID- 29191015 TI - Dynamics Sampling in Transition Pathway Space. AB - The minimum energy pathway contains important information describing the transition between two states on a potential energy surface (PES). Chain-of states methods were developed to efficiently calculate minimum energy pathways connecting two stable states. In the chain-of-states framework, a series of structures are generated and optimized to represent the minimum energy pathway connecting two states. However, multiple pathways may exist connecting two existing states and should be identified to obtain a full view of the transitions. Therefore, we developed an enhanced sampling method, named as the direct pathway dynamics sampling (DPDS) method, to facilitate exploration of a PES for multiple pathways connecting two stable states as well as addition minima and their associated transition pathways. In the DPDS method, molecular dynamics simulations are carried out on the targeting PES within a chain-of-states framework to directly sample the transition pathway space. The simulations of DPDS could be regulated by two parameters controlling distance among states along the pathway and smoothness of the pathway. One advantage of the chain-of-states framework is that no specific reaction coordinates are necessary to generate the reaction pathway, because such information is implicitly represented by the structures along the pathway. The chain-of-states setup in a DPDS method greatly enhances the sufficient sampling in high-energy space between two end states, such as transition states. By removing the constraint on the end states of the pathway, DPDS will also sample pathways connecting minima on a PES in addition to the end points of the starting pathway. This feature makes DPDS an ideal method to directly explore transition pathway space. Three examples demonstrate the efficiency of DPDS methods in sampling the high-energy area important for reactions on the PES. PMID- 29191016 TI - Room-Temperature Mid-Infrared Emission from Faceted InAsSb Multi Quantum Wells Embedded in InAs Nanowires. AB - There is considerable interest in the development of InAsSb-based nanowires for infrared photonics due to their high tunability across the infrared spectral range, high mobility, and integration with silicon electronics. However, optical emission is currently limited to low temperatures due to strong nonradiative Auger and surface recombination. Here, we present a new structure based on conical type II InAsSb/InAs multiquantum wells within InAs nanowires which exhibit bright mid-infrared photoluminescence up to room temperature. The nanowires are grown by catalyst-free selective area epitaxy on silicon. This unique geometry confines the electron-hole recombination to within the quantum wells which alleviates the problems associated with recombination via surface states, while the quantum confinement of carriers increases the radiative recombination rate and suppresses Auger recombination. This demonstration will pave the way for the development of new integrated quantum light sources operating in the technologically important mid-infrared spectral range. PMID- 29191017 TI - Development of Antifouling Hyperbranched Polyglycerol Layers on Hydroxyl Poly-p xylylene Coatings. AB - Antifouling surfaces that are resistant to protein adsorption and cell adhesion are desirable for many biomedical devices, such as diagnostic devices, biosensors, and implants. In this study, we developed an antifouling hyperbranched polyglycerol (hPG) surface on hydroxyl poly-p-xylylene (PPX-OH). PPX-OH was deposited via chemical vapor deposition (CVD), and an hPG film was then developed via the ring-opening reaction of glycidol. The hPG film greatly reduced the adhesion of L929 cells and platelets as well as protein adsorption. The addition of alkenyl groups in the hPG layer allows the conjugation of biomolecules, such as peptides and biotin, and elicits specific biological interactions. Since the CVD deposition of PPX-OH could be applied to most types of materials, our approach makes it possible to decorate an antifouling hPG film on most types of materials. Our method could be applied to biosensors, diagnostics, and biomedical devices in the future. PMID- 29191018 TI - Production of N2O5 and ClNO2 through Nocturnal Processing of Biomass-Burning Aerosol. AB - Biomass burning is a source of both particulate chloride and nitrogen oxides, two important precursors for the formation of nitryl chloride (ClNO2), a source of atmospheric oxidants that is poorly prescribed in atmospheric models. We investigated the ability of biomass burning to produce N2O5(g) and ClNO2(g) through nocturnal chemistry using authentic biomass-burning emissions in a smog chamber. There was a positive relationship between the amount of ClNO2 formed and the total amount of particulate chloride emitted and with the chloride fraction of nonrefractory particle mass. In every fuel tested, dinitrogen pentoxide (N2O5) formed quickly, following the addition of ozone to the smoke aerosol, and ClNO2(g) production promptly followed. At atmospherically relevant relative humidities, the particulate chloride in the biomass-burning aerosol was rapidly but incompletely displaced, likely by the nitric acid produced largely by the heterogeneous uptake of N2O5(g). Despite this chloride acid displacement, the biomass-burning aerosol still converted on the order of 10% of reacted N2O5(g) into ClNO2(g). These experiments directly confirm that biomass burning is a potentially significant source of atmospheric N2O5 and ClNO2 to the atmosphere. PMID- 29191019 TI - Affinity of Ketamine to Clinically Relevant Transporters. AB - Ketamine is a widely used intravenous anesthetic drug that has also a pronounced analgesic effect. Moreover, one of its metabolites was very recently shown to possess antidepressant activity. Consequently, oral administration of ketamine may become of interest in the future. There is evidence from in vitro data, drug drug interactions, and the physicochemical properties of the drug that ketamine may be a substrate of drug transporters. Thus, it was the aim of this study to investigate the affinity of ketamine to clinically relevant transporter proteins that are expected to affect its intestinal absorption, distribution, and excretion. Ketamine was shown to be significantly taken up in a time- and concentration-dependent manner by OCT1-3. The affinity to OCT transporters at pH 6.5 (Km ~ 35-75 MUM) was clearly higher than that at pH 7.4. In addition, ketamine permeability was markedly lower at pH 6.5 than at pH 7.4 in a parallel artificial membrane permeability assay (PAMPA). Ketamine showed a low but significant affinity to P-gp at pH 6.5. In contrast to this, we could not detect any transport of ketamine by MATE1/2K. In conclusion, ketamine is a substrate for OCT1-3 and P-gp but is not recognized by MATE1/2K. Considering that ketamine is a lipophilic base that mainly exists as a cationic moiety (>90%) in the intestinal lumen, we conclude that the OCT-mediated cellular uptake as well as P-gp efflux is expected to be only of relevance in the human intestine (i.e., in the case of oral drug administration), where OCT1, OCT3, and P-gp are stably expressed at the apical membrane. On the other side, P-gp is not expected to contribute significantly to tissue (brain) distribution or renal excretion of ketamine. PMID- 29191021 TI - Dealkanative Main Group Couplings across the peri-Gap. AB - Here, we highlight the ability of peri-substitution chemistry to promote a series of unique P-P/P-As coupling reactions, which proceed with concomitant C-H bond formation. This dealkanative reactivity represents an interesting and unexpected expansion to the established family of main-group dehydrocoupling reactions. These transformations are exceptionally clean, proceeding essentially quantitatively at relatively low temperatures (70-140 degrees C), with 100% diastereoselectivity in the products. The reaction appears to be radical in nature, with the addition of small quantities of a radical initiator (azobis(isobutyronitrile)) increasing the rate dramatically, as well as altering the apparent order of reaction. DFT calculations suggest that the reaction involves dissociation of a phosphorus centered radical (stabilized by the peri backbone) to the P-P coupled product and a free propyl radical, which carries the chain. This unusual reaction demonstrates the powerful effect that geometric constraints, in this case a rigid scaffold, can have on the reactivity of main group species, an area of research that is gaining increasing prominence in recent years. PMID- 29191020 TI - Highly Tunable Electronic Structures of Phosphorene/Carbon Nanotube Heterostructures through External Electric Field and Atomic Intercalation. AB - Black phosphorene (BP)/carbon nanotube (CNT) heterostructures can be classified as either type I or II, depending on the size of the CNTs. An external electric field (Eext) can modulate the interfacial electronic structures and separate the electron and hole carriers of the BP/CNT heterostructures. The giant Stark effect is observed, and the band gap of the semiconducting heterostructures can vary several-fold. The intercalation of 3d transition metals can strongly bond BP and CNTs together. Furthermore, strong ferromagnetism with Curie temperature (TC) above room temperature is predicted. It is expected that these BP/CNT heterostructures will provide new opportunities and applications in the fields of optoelectronics and electronics as well as spintronics. PMID- 29191022 TI - Phonon-Driven Oscillatory Plasmonic Excitonic Nanomaterials. AB - We demonstrate that coherent acoustic phonons derived from plasmonic nanoparticles can modulate electronic interactions with proximal excitonic molecular species. A series of gold bipyramids with systematically varied aspect ratios and corresponding localized surface plasmon resonance energies, functionalized with a J-aggregated thiacarbocyanine dye molecule, produces two hybridized states that exhibit clear anticrossing behavior with a Rabi splitting energy of 120 meV. In metal nanoparticles, photoexcitation generates coherent acoustic phonons that cause oscillations in the plasmon resonance energy. In the coupled system, these photogenerated oscillations alter the metal nanoparticle's energetic contribution to the hybridized system and, as a result, change the coupling between the plasmon and exciton. We demonstrate that such modulations in the hybridization are consistent across a wide range of bipyramid ensembles. We also use finite-difference time domain calculations to develop a simple model describing this behavior. Such oscillatory plasmonic-excitonic nanomaterials offer a route to manipulate and dynamically tune the interactions of plasmonic/excitonic systems and unlock a range of potential applications.

AB - Esters are valuable electrophiles for cross-coupling due to their ubiquity and ease of synthesis. However, harsh conditions are traditionally required for the effective cross-coupling of ester substrates. Utilizing a recently discovered precatalyst, Pd-catalyzed Suzuki-Miyaura and Buchwald-Hartwig reactions involving cleavage of the C(acyl)-O bond of aryl esters that proceed under mild conditions are reported. The Pd(II) precatalyst is highly active because it is reduced to the Pd(0) active species more rapidly than previous precatalysts. PMID- 29191024 TI - Pretargeted PET Imaging Using a Bioorthogonal 18F-Labeled trans-Cyclooctene in an Ovarian Carcinoma Model. AB - In cancer research, pretargeted positron emission tomography (PET) imaging has emerged as an effective two-step approach that combines the excellent target affinity and selectivity of antibodies with the advantages of using short-lived radionuclides such as fluorine-18. One possible approach is based on the bioorthogonal inverse-electron-demand Diels-Alder (IEDDA) reaction between tetrazines and trans-cyclooctene (TCO) derivatives. Here, we report the first successful use of an 18F-labeled small TCO compound, [18F]1 recently developed in our laboratory, to perform pretargeted immuno-PET imaging. The study was performed in an ovarian carcinoma mouse model, using a trastuzumab-tetrazine conjugate. PMID- 29191025 TI - Progress and Future Direction of Chromosome-Centric Human Proteome Project.

AB - In this work, screening of Lauraceae species for their antifungal activity against Collectotrichum tamarilloi was carried out and the ethanol extract derived from the bark of Endlicheria arenosa was found to be the best candidate. From the ethanolic extract of the bark of E. arenosa, the hexane and chloroform fractions were found to be active, from these five fatty acids were identified and two lactones were isolated. The most active fatty acid was the dodecanoic acid with a minimal inhibitory concentration (MIC) of 78.0 MUM. The butyrolactone 3R,4R-licunolide A, it has not previously reported, and licunolide B show both the lowest MIC (55.3 MUM). This is the first report of compounds of natural origin as growth inhibitors of C. tamarilloi. PMID- 29191042 TI - Optimization on biodistribution and antitumor activity of tripterine using polymeric nanoparticles through RES saturation. AB - Systemic delivery of tripterine (TPR) is challenged by its insoluble property and unsuitable pharmacokinetics. This work aimed to develop polymeric nanoparticles (NPs) combined with the reticuloendothelial system (RES) saturation to improve the in vivo distribution and antitumor activity of TPR. TPR-loaded nanoparticles (TPR-NPs) were prepared by the low-energy emulsification/evaporation method and characterized with particle size, entrapment efficiency, and morphology. The resulting TPR-NPs were 75 nm around in particle size and displayed a sustained drug release in pH 7.4 medium. Pharmacokinetic studies revealed that TPR-NPs had the advantage in bettering the pharmacokinetic properties of TPR over the solution formulation. However, the ameliorative effect on pharmacokinetics was more significant in the case of RES saturation (i.e. preinjection of blank NPs). Preinjection of blank NPs followed by injection of TPR-NPs resulted in higher distribution of TPR into the tumor due to reduced sequestration of TPR-NPs by RES. In tumor-bearing mice (prostatic cancer model), TPR-NPs treatment with RES saturation exhibited a superior antitumor efficacy to free TPR and TPR-NPs alone. It can be concluded that formulating TPR into polymeric NPs in combination with RES saturation is an effective means to address the systemic delivery of TPR.

AB - INTRODUCTION: It is well recognized that a lesion that does not cause a hemodynamically significant stenosis can trigger a sudden cardiac event through plaque rupture. As a diagnostic tool, intravascular imaging was developed to circumvent limitations of coronary angiography; however, none of the intravascular imaging devices are individually able to provide complete assessment of the plaque morphology, geometry, physiology and biology. Therefore, over the past few years an effort was made to develop hybrid intravascular imaging catheters to provide more complete evaluation of coronary plaque pathobiology. Areas covered: This paper aims to give an overview of the recent developments on 1) single-modality intravascular imaging devices; 2) hybrid intravascular imaging devices and 3) the hemodynamic analysis in models reconstructed from the fusion of intravascular imaging and angiographic data. Expert commentary: Within five years, most of the hybrid imaging techniques which are now in pre-clinical phase will be utilized in the clinical arena, as NIRS IVUS. Software for online blood simulation is likely to be developed that will enable ESS calculation while the patient is in the catheterization laboratory. PMID- 29191045 TI - Corrigendum.

PMID- 29191047 TI - Stealth lipid polymer hybrid nanoparticles loaded with rutin for effective brain delivery - comparative study with the gold standard (Tween 80): optimization, characterization and biodistribution. AB - The blood-brain barrier is considered the leading physiological obstacle hindering the transport of neurotherapeutics to brain cells. The application of nanotechnology coupled with surfactant coating is one of the efficacious tactics overcoming this barrier. The aim of this study was to develop lipid polymer hybrid nanoparticles (LPHNPs), composed of a polymeric core and a phospholipid shell entangled, for the first time, with PEG-based surfactants (SAA) viz. TPGS or Solutol HS 15 in comparison with the gold standard Tween 80, aiming to enhance brain delivery and escape opsonization. LPHNPs were successfully prepared using modified single-step nanoprecipitation technique, loaded with the flavonoid rutin (RU), extracted from the flowers of Calendula officinalis L., and recently proved as a promising anti-Alzheimer. The effect of the critical process parameters (CPP) viz. PLGA amount, Wlecithin/WPLGA ratio, and Tween 80 concentration on critical quality attributes (CQA); entrapment, size and size distribution, was statistically analyzed via design of experiments, and optimized using the desirability function. The optimized CPP were maintained while substituting Tween 80 with other PEG-SAA. All hybrid particles exhibited spherical shape with perceptible lipid shells. The biocompatibility of the prepared NPs was confirmed by hemolysis test. The pharmacokinetic assessments, post-intravenous administration to rats, revealed a significant higher RU bioavailability for NPs relative to drug solution. Biodistribution studies proved non-significant differences in RU accumulation within brain, but altered phagocytic uptake among various LPHNPs. The present study endorses the successful development of LPHNPs using PEG-SAA, and confirms the prospective applicability of TPGS and Solutol in enhancing brain delivery. PMID- 29191048 TI - Drug delivery vectors based on filamentous bacteriophages and phage-mimetic nanoparticles. AB - With the development of nanomedicine, a mass of nanocarriers have been exploited and utilized for targeted drug delivery, including liposomes, polymers, nanoparticles, viruses, and stem cells. Due to huge surface bearing capacity and flexible genetic engineering property, filamentous bacteriophage and phage mimetic nanoparticles are attracting more and more attentions. As a rod-like bio nanofiber without tropism to mammalian cells, filamentous phage can be easily loaded with drugs and directly delivered to the lesion location. In particular, chemical drugs can be conjugated on phage surface by chemical modification, and gene drugs can also be inserted into the genome of phage by recombinant DNA technology. Meanwhile, specific peptides/proteins displayed on the phage surface are able to conjugate with nanoparticles which will endow them specific-targeting and huge drug-loading capacity. Additionally, phage peptides/proteins can directly self-assemble into phage-mimetic nanoparticles which may be applied for self-navigating drug delivery nanovehicles. In this review, we summarize the production of phage particles, the identification of targeting peptides, and the recent applications of filamentous bacteriophages as well as their protein/peptide for targeting drug delivery in vitro and in vivo.

AB - The current study investigated the rates of addictions to Internet use, online gaming, and online social networking as well as their associations with depressive symptoms among young adults in China, Singapore, and the United States. A total of 3267 undergraduate students were recruited. Psychological instruments were used to assess various Internet-related addictions and depressive symptoms. Male students were more addicted to Internet and online gaming whereas female students were more addicted to online social networking. Compared with students in the United States, Chinese and Singaporean students were more addicted to Internet use and online social networking but less to online gaming. The odds of depression among students with addiction to various Internet-related addictions were highest in China. Internet-related addiction is a new public health concern of young adults, especially in the Asia-Pacific regions. It is found to associate with depressive symptoms. Strategies should address this phenomenon with attention to specific needs of gender and region while managing mood disturbances.

AB - A new isoprenylated sanggenon-type flavanone, nigrasin K (1), together with three known analogs (2-4) and five known Diels-Alder adducts (5-9), were isolated from the twigs of Morus nigra. Their structures were elucidated by spectroscopic methods. Sanggenon M (2), chalcomoracin (5), sorocein H (6), kuwanon J (7), sanggenon C (8), and sanggenon O (9) showed significant inhibitory effects on mushroom tyrosinase. PMID- 29191051 TI - Preoperative evaluation of moyamoya spontaneous anastomosis of combined revascularization donor vessels in adults by duplex ultrasonography. AB - OBJECTIVE: To evaluate the preoperative diagnostic value of duplex ultrasonography in moyamoya spontaneous anastomosis of combined revascularization donor vessels in adults. METHODS: A total of 99 preoperative adult patients who underwent superficial temporal artery-to-middle cerebral artery (STA-MCA) anastomosis were retrospectively analyzed. Each side of the cerebral hemisphere was examined as a separate procedure. A total of 198 cerebral hemispheres were divided into three groups: a collateral, non-collateral, and control group based on digital subtraction angiography (DSA). Hemodynamic parameters, including peak systolic velocity (PSV), end diastolic velocity (EDV), and resistance index (RI) were analyzed. RESULTS: There were only four of cases (5%, 4/198) of STA spontaneous anastomosis, whereas those of maxillary artery (MA) anastomosis were 44 (23.7%, 44/186). Compared with the control group, MA PSV and EDV of the collateral group increased significantly, while RI decreased significantly (p < .05). The area under the curve (AUC) of MA RI was 0.654. As a predictor of MA spontaneous anastomosis, duplex ultrasonography had high specificity but poor sensitivity. In collateral group, PSV and EDV detected two weeks post-surgery were significantly higher than those detected pre-operatively (PSV: p = .018, EDV: p = .025). By contrast, there were no significant difference of the PSV and EDV detected six months post-surgery compared with pre-operation (PSV: p = .450, EDV: p = .099). Additionally, MA RI in two weeks after the surgery was comparable with preoperative values. CONCLUSIONS: Duplex ultrasonography could be applied to evaluate the adult moyamoya spontaneous anastomoses of MA preoperatively. Despite its poor sensitivity, this diagnostic modality is still reliable and specific. STA-MCA anastomosis combined with EDMS did not affect MA pre-operative spontaneous anastomosis. PMID- 29191052 TI - A randomized controlled trial of resistance and endurance exercise in amyotrophic lateral sclerosis. AB - OBJECTIVE: Evaluate the safety and tolerability of resistance and endurance exercise in ALS participants as measured by their ability to complete this six month study. METHODS: Participants were randomized to Resistance, Endurance, or Stretching/Range of Motion (SROM the exercise regimen prescribed for most ALS patients) exercises. All exercises were performed at home with an individualized regimen designed by a physical therapist trained in ALS management. Primary outcome measures were tolerability of the exercises at 24 weeks defined by 50% of participants completing at least 50% of the prescribed exercise regimen. Secondary outcome measures included the ALSFRS-R, pulmonary FVC, and other measures of ALS function. RESULTS: At 12 and 24 weeks, all three exercise regimens were tolerated according to our pre-specified criteria. Compliance to the prescribed exercise regimen was the highest in the resistance and SROM arms of the study. All three forms of exercise were considered safe as there were no differences in the rates of disease progression among groups. There were no differences in the secondary outcome measures and feasibility for evaluating these measures was successful. In a post-hoc analysis, there was a trend towards fewer falls in the Resistance and Endurance groups. CONCLUSIONS: This study demonstrates that SROM, resistance, and endurance exercise are all safe to be performed with the specified regimen without any worsening of outcomes as related to ALS function. All three forms of exercise were tolerated with resistance and SROM exercises showing the highest compliance over the 24 week-period. PMID- 29191053 TI - Diagnosis and Management of Conjunctivitis for the Dermatologist. AB - Atopic dermatitis is a chronic, sometimes relapsing inflammatory skin condition that presents with pruritus and characteristic skin manifestations. Conjunctivitis is a common ocular comorbidity affecting almost half of patients with the risk increasing with atopic dermatitis severity. Recent targeted biologic therapies that successfully treat atopic skin disease, including dupilumab, which blocks interleukin (IL)-4 and IL-13, as well as agents that block IL-13 alone, have been associated with an increased rate of conjunctivitis in clinical trials. Because conjunctivitis commonly occurs in patients with atopic dermatitis and as the treatment with targeted biologic agents may increase the risk or severity of conjunctivitis, it is important that dermatologists recognize symptoms, appreciate treatment options, and know when referral to an ophthalmologist is appropriate. PMID- 29191054 TI - Onychomycosis and Chronic Fungal Disease: Exploiting a Commensal Disguise to Stage a Covert Invasion. AB - Onychomycosis is a chronic fungal infection that is recalcitrant to treatment and often results in relapse. New evidence suggests that disease prognosis may be linked to pathogens manipulating host immune responses. Therefore, individuals with specific mutations, including those affecting pattern recognition receptors or the interleukin (IL)-17 and IL-22 pathways, may be more susceptible to infection. Moreover, it is recommended that those with a family history of immune mutations or predisposition to fungal disease be treated aggressively for onychomycosis prior to symptom progression. In addition, incorporating genetic testing and new investigational therapy such as IL-33 and interferon-gamma may improve treatment outcome. PMID- 29191055 TI - Recurrence after pulmonary vein isolation is associated with low contact force. AB - OBJECTIVES: Recurrent arrhythmia after pulmonary vein isolation (PVI) by radiofrequency (RF) ablation in patients with atrial fibrillation (AFIB) remains a significant challenge. Using contact force (CF) sensing ablation catheters, we aimed to identify procedure related parameters associated with recurrence after de-novo PVI in patients with AFIB. METHODS: Consecutive patients undergoing a de novo PVI procedure (n = 120, 63% paroxysmal and 37% persistent AFIB) employing a force-sensing ablation catheter were included. A clinical control including electrocardiogram and 120 hour of Holter-recording at 12-months was performed in all patients. Recurrence was defined as any documented AFIB or atrial flutter more than 30 seconds on Holter-recording after an initial blanking period of three months. RESULTS: Recurrence occurred in 44 patients (37%). Mean CF was lower in patients with recurrent arrhythmia (22.2 +/- 9.5 vs. 28.8 +/- 9.3 g, p < .001). In multi-variable analyses lower mean CF (OR 0.9 (95% CI 0.8-1.0), p = .03), and higher percentage of ablation time with a CF <10 grams (OR 1.1 (95% CI 1.0-1.1), p = .004) were both associated with recurrence in two distinct models. Dragging during ablation compared with point-by-point ablation technique was associated with recurrence in both models (OR 19.2 (95% CI 2.9-130.0), p = .002, and OR 21.7 (95% CI 2.7-176.2), p = .004). CONCLUSIONS: Low CF and dragging during ablation as compared with point-by-point ablation technique were associated with recurrent arrhythmia in patients with AFIB undergoing de-novo PVI by RF ablation. PMID- 29191056 TI - Emotional distress and subjective impact of the disease in young women with breast cancer and their spouses. AB - AIM: Evaluate the influence of emotional distress of young women with breast cancer and their spouses on their daily subjective experience of the disease, through application of the Actor-Partner Interdependence Model. PATIENTS & METHODS: A total of 112 women under 45 years of age were diagnosed with nonmetastatic breast cancer and their spouses answered self-reported measures of anxiety, depression and subjective experience of the disease and its treatment. RESULTS: The patient's emotional distress influenced more the subjective experience of her spouse than the spouse's emotional distress influenced the patient. The spouse's difficulties depended as much on his own distress level as on the patient's distress level. CONCLUSION: These data confirm the importance of implementing couple-focused interventions. PMID- 29191057 TI - Co-delivery nanoparticles of anti-cancer drugs for improving chemotherapy efficacy. AB - To achieve superior therapeutic efficacy, the combination chemotherapy using two or more anticancer drugs in clinical practice has been generally accepted as a feasible strategy. On account of the concept of combination chemotherapy, co delivery of anticancer drugs with nanotechnology gradually becomes a desired strategy and one of the research frontiers on modern drug delivery. In recent years, nano drug co-delivery system (NDCDS), which loads at least two anticancer drugs with different physicochemical and pharmacological properties into a combination delivery system, has achieved rapid development. NDCDS synergistically inhibited the growth of the tumor compared with the free drugs. In this review, we highlighted the current state of co-delivery nanoparticles and the most commonly used nanomaterial, discussed challenges and strategies, and prospect future development. PMID- 29191058 TI - Nanoemulsion-based delivery system for enhanced oral bioavailability and caco-2 cell monolayers permeability of berberine hydrochloride. AB - Berberine hydrochloride (BBH) has a variety of pharmacological activities such as antitumor, antimicrobial, anti-inflammation, and reduce irritable bowel syndrome. However, poor stability and low oral bioavailability limited its usage. Herein, an oil-in-water nanoemulsion system of BBH was developed to improve its stability and oral bioavailability. The pseudoternary phase diagrams were constructed for the determination of composition of various nanoemulsions. The nanoemulsions of BBH composed of Labrafil M 1944 CS (oil phase), RH-40 (surfactant), glycerin (co surfactant), and water (aqueous phase). The O/W nanoemulsion of BBH showed a relative bioavailability of 440.40% compared with unencapsulated BBH and was stable in our 6-month stability study. Further, there was a significant increase in intestinal permeability of BBH as assessed by Caco-2 cell monolayers and a significant reduction in efflux of BBH by the multidrug efflux pump P glycoprotein. This study confirmed that the nanoemulsion formulation could be used as an alternative oral formulation of BBH to improve its stability, oral bioavailability and permeability. PMID- 29191059 TI - Optimization of biologic therapy in Crohn's disease. AB - INTRODUCTION: Crohn's disease (CD) is a manifestation of inflammatory bowel disease (IBD), which can result in significant morbidity. Biologic therapy with anti-TNF medication has been effective in treating inflammation and reducing complications in CD. It is important for clinicians to have better knowledge of the various biologic therapies including mechanisms of action and optimization strategies. Areas covered: The review describes optimization of biologic therapy in CD including different mechanisms of loss of response, therapeutic drug monitoring in CD, clinical implications and management strategies which utilize drug monitoring, and areas of future development and research in optimization of biologic therapy. Expert opinion: Achieving adequate levels of the drug (antibody unbound) is one of the most important determinants of attaining clinical remission and mucosal healing. Drug level is also critical in determining if a patient requires combination therapy with an immunomodulator. Certain populations, including those with active perianal disease, may require higher serum levels to achieve healing or closure. Treat to target level is an algorithm that is not universally accepted and more data is need. Additionally, there are numerous assays that don't always correlate, especially regarding measuring anti drug antibodies.

Endoscopic endonasal approaches to these lesions in the mesencephalon and pons have been described. In this article the authors present the first case of a medullary cavernoma resected by an endoscopic transclival approach. A 26 year-old woman with a 1.5 cm medullary cavernoma presented with imbalance, swallowing difficulty, and right hemibody weakness. She was taken to the operating room for endoscopic endonasal transclival resection. Her pre-existing neurologic deficits worsened initially after surgery, but at three-month follow-up she had made a full neurologic recovery. PMID- 29191061 TI - The identification of new ATAD2 bromodomain inhibitors: the application of combined ligand and structure-based virtual screening. AB - Ligand-based virtual screening (LBVS) and structure-based virtual screening (SBVS) approaches were used to identify new inhibitors for ATAD2 bromodomain. The LBVS approach was used to search 23,129,083 clean compounds to identify compounds similar to an active compound with reported pIC50 equal to 7.2. Based on LBVS results, 19 compounds were selected. To perform SBVS, by applying nine filters on 23,129,083 clean compounds, 1,057,060 compounds were selected. After performing SBVS on these selected compounds with idock software, 16 compounds with the lowest binding energies were selected. More accurate molecular docking analysis was performed on these 35 selected compounds by using iGEMDOCK software and six of them with the lowest binding energies were selected as hit compounds. These compounds were zinc36647229, zinc77969074, zinc13637358, zinc77971540, zinc12991296 and zinc19374204.

AB - We present the case of a 15 year old boy who developed transient lower motor neuron facial weakness on two separate occasions shortly after ventriculoperitoneal shunt insertion. Both episodes, each of which occurred on the ipsilateral side to shunt insertion, were transient, self-limiting and were managed medically with a course of oral steroids. We believe this is the first reported case of Bell's palsy after this type of surgery in a child. Potential pathophysiological mechanisms are discussed.

AB - This study was designed to assess the epigenetic alterations in blood cells, induced by occupational exposure to multi-wall carbon nanotubes (MWCNT). The study population comprised of MWCNT-exposed workers (n=24) and unexposed controls (n=43) from the same workplace. We measured global DNA methylation/hydroxymethylation levels on the 5th cytosine residues using a validated liquid chromatography tandem-mass spectrometry (LC-MS/MS) method. Sequence-specific methylation of LINE1 retrotransposable element 1 (L1RE1) elements, and promoter regions of functionally important genes associated with epigenetic regulation [DNA methyltransferase-1 (DNMT1) and histone deacetylase 4 (HDAC4)], DNA damage/repair and cell cycle pathways [nuclear protein, coactivator of histone transcription/ATM serine/threonine kinase (NPAT/ATM)], and a potential transforming growth factor beta (TGF-beta) repressor [SKI proto-oncogene (SKI)] were studied using bisulfite pyrosequencing. Analysis of global DNA methylation levels and hydroxymethylation did not reveal significant difference between the MWCNT-exposed and control groups. No significant changes in Cytosine-phosphate Guanine (CpG) site methylation were observed for the LINE1 (L1RE1) elements. Further analysis of gene-specific DNA methylation showed a significant change in methylation for DNMT1, ATM, SKI, and HDAC4 promoter CpGs in MWCNT-exposed workers. Since DNA methylation plays an important role in silencing/regulation of the genes, and many of these genes have been associated with occupational and smoking-induced diseases and cancer (risk), aberrant methylation of these genes might have a potential effect in MWCNT-exposed workers. PMID- 29191065 TI - Physiological responses of the Drosophila labellum to amino acids. AB - We have systematically studied the physiological responses elicited by amino acids from the principal taste organ of the Drosophila head. Although the detection and coding of sugars and bitter compounds have been examined extensively in this organism, little attention has been paid to the physiology of amino acid taste. We find that one class of sensilla, the S sensilla, yield the strongest responses to amino acids, although these responses were much weaker than the most robust responses to sugar or bitter compounds. S sensilla are heterogeneous in their amino acid responses and amino acids differ in the responses they elicit from individual sensilla. Tryptophan elicited relatively strong responses from S sensilla and these responses were eliminated when bitter sensing neurons were ablated. Although tryptophan yielded little if any response in a behavioral paradigm, phenylalanine elicited a relatively strong response in the same paradigm and had a different physiological profile, supporting the notion that different amino acids are differentially encoded by the repertoire of taste neurons. PMID- 29191066 TI - Intervention effect of gamma aminobutyric acid on anxiety behavior induced by phthalate (2-ethylhexyl ester) in rats. AB - BACKGROUND: Di(2-ethylhexyl) phthalate (DEHP) is one of the most widely used phthalate esters. The application of DEHP has caused serious environmental pollution and posed a threat to human health. METHODS: A total of 30 male Sprague Dawley rats were randomly divided into control group, DEHP group (500 mg/kg DEHP), low GABA (Gama-aminobutyric acid) group (500 mg/kg DEHP and 1 mg/kg GABA), medium GABA group (500 mg/kg DEHP and 2 mg/kg GABA) and high GABA group (500 mg/kg DEHP and 4 mg/kg GABA). The interventions continued for 30 consecutive days. Open-field test and elevated plus-maze test were used to detect behavioral changes of rats before and after interventions. RESULTS: The levels of nitric oxide and nitric oxide synthase in prefrontal cortex of rats were measured using enzyme-linked immunosorbent assay. DEHP and GABA treatment had no significant effects on the body weight of rats. GABA restored food utilization rate of rats impaired by DEHP to the level of healthy rats. According to open-field test and elevated plus-maze test, GABA alleviated the effects of DEHP on rat behaviors. Enzyme-linked immunosorbent assay showed that GABA was effective in reducing the levels of nitric oxide and nitric oxide synthase in rats treated with DEHP. CONCLUSION: DEHP exposure induced anxiety in rats, which may be achieved through elevating nitric oxide and nitric oxide synthase levels in prefrontal cortex of rats. However, the effects caused by DEHP could be alleviated by GABA. PMID- 29191067 TI - Differences in pain intensity in anti- and pro-nociceptive pain profile subgroups in patients with knee osteoarthritis. AB - AIM: Facilitated temporal summation is one component of central sensitization. The aim of this exploratory study was to classify pro-, eu- and antinociceptive subgroups based on wind-up ratio cut-off scores in patients with knee osteoarthritis (OA). PATIENTS & METHODS: A total of 56 patients with knee OA met the inclusion criteria. Temporal summation was measured and wind-up ratio was calculated. Reference values of 180 healthy subjects were used to define wind-up ratio cut-off scores. RESULTS: Twenty-seven percent of patients showed a pro nociceptive pain profile. Sixteen percent of patients showed an anti-nociceptive pain profile. A eu-nociceptive pain profile was present in 57% of patients. CONCLUSION: Central pain sensitization was present in approximately a third of knee OA patients. The results should be confirmed in larger studies. PMID- 29191068 TI - An exploratory cost-effectiveness analysis of systemic treatments for cutaneous T cell lymphoma. AB - PURPOSE: To conduct an exploratory cost-effectiveness analysis of systemic treatment options for more advanced cutaneous T-cell lymphoma (CTCL). METHODS: A cost-effectiveness model compared systemic bexarotene, denileukin diftitox, interferon-alpha, methotrexate, pralatrexate, romidepsin, vorinostat, and extracorporeal photopheresis (ECP) treatment of CTCL. Treatment effectiveness data were extracted from published studies and/or US product labeling. Overall response, the primary effectiveness measure, was defined as the proportion of patients achieving complete or partial response. Costs were based on wholesale acquisition cost (medications) and Medicare reimbursement rates (ECP, medication administration, adverse drug effect treatment). The perspective of the study was from that of a payer. RESULTS: Methotrexate was the lowest cost option [mean $436; standard deviation (SD) $284], followed by interferon-alpha (mean $32,174; SD $27,582), denileukin difitox (mean $40,107; SD $18,598), and ECP (mean $40,985; SD $45,633). Other treatments had costs greater than $50,000, ranging from vorinostat ($65,958; SD $40,637) to bexarotene ($239,424; SD $178,881). The incremental cost-effectiveness ratio per successfully treated patient was $396,725 (interferon) and $213,416 (ECP). Denileukin diftitox, romidepsin, and vorinostat were less effective and cost more than methotrexate. CONCLUSION: Methotrexate is the most cost-effective option for CTCL; however, its low cost is offset by its limited effectiveness in advanced stages of CTCL. ECP and interferon appear the next most cost-effective therapies. PMID- 29191069 TI - Information needs of survivors and families after childhood CNS tumor treatment: a population-based study. AB - BACKGROUND: This study examines information needs and satisfaction with provided information among childhood central nervous system (CNS) tumor survivors and their parents. MATERIAL AND METHODS: In a population-based sample of 697 adult survivors in Sweden, 518 survivors and 551 parents provided data. Information needs and satisfaction with information were studied using a multi-dimensional standardized questionnaire addressing information-related issues. RESULTS: Overall, 52% of the survivors and 48% of the parents reported no, or only minor, satisfaction with the extent of provided information, and 51% of the survivors expressed a need for more information than provided. The information received was found useful (to some extent/very much) by 53%, while 47% did not find it useful, or to a minor degree only. Obtaining written material was associated with greater satisfaction and usefulness of information. Dissatisfaction with information was associated with longer time since diagnosis, poorer current health status and female sex. The survivors experienced unmet information needs vis-a-vis late effects, illness education, rehabilitation and psychological services. Overall, parents were more dissatisfied than the survivors. CONCLUSION: These findings have implications for improvements in information delivery. Information in childhood CNS tumor care and follow-up should specifically address issues where insufficiency was identified, and recognize persistent and with time changing needs at the successive stages of long-term survivorship. PMID- 29191070 TI - Predictors of Mortality in Nondemented Patients With Parkinson Disease: Motor Symptoms Versus Nonmotor Symptoms. AB - BACKGROUND AND OBJECTIVE: The aim of this study is to identify risk factors for mortality in a community-based cohort of nondemented patients with Parkinson disease (PD) during prospective long-term follow-up, while also comparing the effect of motor complications to nonmotor symptoms (NMS) on risk of mortality. METHODS: One hundred forty seven nondemented patients with PD (57.1% males; 70.9 +/- 8.6 years old) were included in this 48 month follow-up, longitudinal, single, evaluation study. Motor and therapy-related complications were assessed using the Unified Parkinson's Disease Rating Scale/part-IV (UPDRS-IV). Non-Motor Symptoms Scale (NMSS) total score was used to assess NMS burden. Cox proportional hazard models were applied to identify independent predictors of mortality during follow-up. RESULTS: Twenty-two patients of 146 (15.1%) died (1 case without information). Both UPDRS-IV and NMSS total scores were higher at baseline in patients with PD who died (3.5 +/- 3.1 vs 2.4 +/- 2.4, P = .049 and 96.9 +/- 58.6 vs 61.9 +/- 51.0, P = .004, respectively). Unadjusted hazard ratios (HRs) associated with UPDRS-IV and NMSS total scores among those who died during follow up were 1.171 (95% confidence interval [CI]: 1.012-1.357; P = .035) and 1.008 (95% CI: 1.002-1.013; P = .006), respectively. Independent predictors of mortality during follow-up after adjusting for other covariates were UPDRS-IV (HR: 1.224; 95% CI: 1.002-1.494; P = .047), age (HR: 1.231; 95% CI: 1104-1.374; P < .0001), and comorbidity (Charlson Index; HR: 1.429; 95% CI: 1.023-1.994; P = .036), but not NMSS total score (HR: 1.005; 95% CI: 0.996-1.014; P = .263). CONCLUSIONS: Both motor complications (UPDRS-IV) and NMS (NMSS) were associated with mortality at 4 years, being motor complications an independent predictor of it. PMID- 29191071 TI - Allosteric activation of cytochrome P450 3A4 by efavirenz facilitates midazolam binding. AB - 1. The purpose of this study is to investigate the heteroactivation mechanism of CYP3A4 by efavirenz, which enhances metabolism of midazolam in vivo, in terms of its binding to CYP3A4 with in vitro spectroscopic methods. 2. Efavirenz exhibited a type II spectral change with binding to CYP3A4 indicating a possible inhibitor. Although dissociation constant (K d) was approximated as 520 MUM, efavirenz enhanced binding affinity of midazolam as a co-existing drug with an estimated iK d value of 5.6 uM which is comparable to a clinical concentration. 3. Efavirenz stimulated the formation of 1'-hydroxymidazolam, and the product formation rate (V max) concentration-dependently increased without changing the K m. Besides, an efavirenz analogue, [6-chloro-1,4-dihydro-4-(1-pentynyl)-4-(trifluoromethyl)-2H 3,1-benzoxazin-2-one] (efavirenz impurity) slightly facilitated the binding affinity of midazolam in a concentration-dependent manner. These results propose that efavirenz affects midazolam-binding via binding to the peripheral site which is apart from the active site of CYP3A4. 4. A molecular dynamics simulation also suggested the bound-efavirenz was repositioned to effector-binding site. As a consequence, our spectroscopic studies clarified the heteroactivation of CYP3A4 caused by efavirenz with a proper affinity to the peripheral site, and we concluded the method can be a useful tool for characterising the potential for drug-drug interactions.

PMID- 29191073 TI - Using an Allometric Equation to Accurately Predict the Energy Expenditure of Children and Adolescents With Nonalcoholic Fatty Liver Disease. AB - BACKGROUND: Pediatric patients with nonalcoholic fatty liver disease (NAFLD) require targeted nutrition therapy that relies on calculating energy needs. Common energy equations are inaccurate in predicting resting energy expenditure (REE), influencing total energy expenditure (TEE) estimates. Equations based on allometric scaling are simple, accurate, void of subjective activity and/or stress factor bias, and they estimate TEE. OBJECTIVE: To investigate the predictive accuracy of an allometric energy equation (AEE) in predicting TEE of children and adolescents with NAFLD. METHODS: Retrospective study performed in a single institution. The allometric equation was used to calculate AEE, and the results were compared with TEE calculated using indirect calorimetry data (measured REE) multiplied by an activity factor (AF) of 1.5 or 1.7. RESULTS: Fifty-six patients with a mean age of 13 years were included in this study. The agreement between TEE (using an AF of 1.5) and AEE was -96 kcal/d (confidence interval, -29 to 221). The predictive accuracy of the allometric equation was not different between obese and nonobese patients. CONCLUSIONS: Allometric equations allow for accurate estimation of TEE in children with NAFLD. PMID- 29191074 TI - Behavioural lateralization in domestic pigs (Sus scrofa)-variations between motor functions and individuals. AB - Motor lateralization is hypothesized to depend on the complexity of the motor function, but it might at the same time reflect hemispheric dominance within an individual across motor functions. We investigated possible motor lateralization patterns in four motor functions of different complexity (snout use in a manipulative task, foot use in two-stepping tasks and tail curling) in the domestic pig, a tetrapod species relevant as farm animal but also as a model in human neuroscience. A significant majority of our sample showed individual biases for manipulation with their snout and for curling their tail. Interestingly, the tail curling was lateralized towards the right at the population level and showed stronger lateralization patterns than the snout. Using a cluster analysis with combined tail and snout laterality, we identified groups of individuals with different lateralization patterns across motor functions that potentially reflect the individuals' hemispheric dominance. To conclude, our results suggest that pigs show lateralization patterns that depend on the motor function and on the individual. Such individual lateralization patterns might have broader implications for animal personality and welfare. Our study lays the methodological groundwork for future research on laterality in pigs. PMID- 29191075 TI - Flavonoids, cytotoxic, antioxidant and antibacterial activities of Evax pygmaea. AB - CONTEXT: Phytochemical study and biological potential of Evax pygmaea (L.) Brot. (Asteraceae) are reported for the first time. OBJECTIVE: To identify the secondary metabolites of Evax pygmaea and to determine its antioxidant, antibacterial and cytotoxic activities. MATERIALS AND METHODS: Dried aerial parts (1 kg) were macerated in 70% MeOH (5 L) during 72 h. The concentrated hydromethanolic extract was subjected to extractions with chloroform (3 * 300 mL), ethyl acetate (3 * 300 mL) and n-butanol (3 * 300 mL), successively. VLC of combined ethyl acetate (EAEP) and n-butanol (BEP) fractions was followed by column purifications. Antioxidant activity was investigated using DPPH, CUPRAC, and metal chelating, beta-carotene/linoleic acid and ABTS assays. Agar method was used in the antibacterial study. Cytotoxic activity was determined by Brine shrimp lethality test in DMSO and ethanol, at varying concentrations (2, 1 and 0.2%) and (1, 0.2 and 0.1%) successively. RESULTS: Quercetin (1), isorhamnetin 3 O-beta-d-xyloside (2), isorhamnetin 3-O-beta-d-glucoside (3), quercetin 3-O-beta d-glucoside (4), quercetin 7-O-beta-D-glucoside (5), patuletin 3-O-beta-d glucoside (6) were isolated from for the first time from Evax genus. The EAEP was the most active in ABTS (IC50: <3.125 MUg/mL) assay whereas the BEEP exhibited the highest activity in the beta-carotene/linoleic acid assay (IC50: <3.125 MUg/mL). The EAEP and BEP exhibited good antibacterial activity (MIC: 40-80 ug/mL). The plant did not show any toxicity (LD50>80 ug/mL). DISCUSSION AND CONCLUSIONS: Six flavonoids were isolated for the first time from Evax pygmaea which exhibited good antioxidant and antibacterial activities. PMID- 29191076 TI - Customized surface-guided knee implant: Contact analysis and experimental test. AB - Contact pressure and stresses on the articulating surface of the tibial component of a total knee replacement are directly related to the joint contact forces and the contact area. These stresses can result in wear and fatigue damage of the ultra-high-molecular-weight polyethylene. Therefore, conducting stress analysis on a newly designed surface-guided knee implant is necessary to evaluate the design with respect to the polyethylene wear. Finite element modeling is used to analyze the design's performance in level walking, stair ascending and squatting. Two different constitutive material models have been used for the tibia component to evaluate the effect of material properties on the stress distribution. The contact pressure results of the finite element analysis are compared with the results of contact pressure using pressure-sensitive film tests. In both analyses, the average contact pressure remains below the material limits of ultra high-molecular-weight polyethylene insert. The peak von Mises stresses in 90 degrees of flexion and 120 degrees of flexion (squatting) are 16.28 and 29.55 MPa, respectively. All the peak stresses are less than the fatigue failure limit of ultra-high-molecular-weight polyethylene which is 32 MPa. The average contact pressure during 90 degrees and 120 degrees of flexion in squatting are 5.51 and 5.46 MPa according to finite element analysis and 5.67 and 8.14 MPa according to pressure-sensitive film experiment. Surface-guided knee implants are aimed to resolve the limitations in activities of daily living after total knee replacement by providing close to normal kinematics. The proposed knee implant model provides patterns of motion much closer to the natural target, especially as the knee flexes to higher degrees during squatting.

AB - Mitochondrial genome (mitogenome) sequences are frequently used to infer phylogenetic relationships of insects at different taxonomic levels. Next generation sequencing (NGS) techniques are revolutionizing many fields of biology, and allow for acquisition of insect mitogenomes for large number of species simultaneously. In this study, 20 full or partial mitogenomes were sequenced from pooled genomic DNA samples by NGS for leaf beetles (Chrysomelidae). Combined with published mitogenome sequences, a higher level phylogeny of Chrysomelidae was reconstructed under maximum likelihood and Bayesian inference with different models and various data treatments. The results revealed support for a basal position of Bruchinae within Chrysomelidae. In addition, two major subfamily groupings were recovered: one including seven subfamilies, namely Donaciinae, Criocerinae, Spilopyrinae, Cassidinae, Cryptocephalinae, Chlamisinae and Eumolpinae, another containing a non monophyletic Chrysomelinae and a monophyletic Galerucinae.

AB - We report a consanguineous family with three affected siblings with novel mutation in the KCNJ10 gene. All three presented with central nervous system symptoms in the form of infantile focal seizures, ataxia, slurred speech with early developmental delay and intellectual disability in two siblings. None had any associated electrolyte abnormalities and no symptomatic hearing deficits were observed. PMID- 29191079 TI - Comparison of semen quality between university-based and private assisted reproductive technology laboratories. AB - OBJECTIVE: Obtaining a semen analysis (SA) is an essential step in evaluating infertile men. Despite using standardized procedures for analysis semen quality in the same individual often varies on repeated tests. The objective of this study was to investigate inter-laboratory variation in semen quality between private- and university-based assisted reproductive technology (ART) laboratories. MATERIALS AND METHODS: IRB approval was obtained to retrospectively evaluate men with a SA at both the private- and university-based ART laboratories. When more than one SA was available from either laboratory, the first at each laboratory was selected for analysis. Comparison of major semen parameters was performed using descriptive statistics and Bland-Altman plots, with differences tested using Wilcoxon-signed rank test. RESULTS: Twenty-eight men aged 33 +/- 5 (mean +/- SD) years were included in the study. Motility was higher at the private laboratories compared to the university-based laboratory (Median difference -12.5%, 95% confidence interval -20.3%; -5.5%). Percent normal morphology was higher at the university-based laboratory compared to private laboratories (5.0%, 3.6%; 6.9%). No significant differences were found in volume, concentration and total motile sperm count although the Bland-Altman plot bias for concentration was clinically significant (15.9 * 106/ml). CONCLUSIONS: In this small series, motility was significantly higher at private laboratories compared to a university-based laboratory but was above WHO reference limits at both places. Normal sperm morphology was significantly lower in semen analyses performed at private laboratories compared to a university-based laboratory and was below WHO reference limits.

AB - While partnerships for health delivery and improvement are frequently described by their structure, goals, and plans, less attention is paid to the interactive relationships among partners or for larger stakeholder groups' coalition memberships. The Give-Get Grid group process tool can be used to assess each stakeholders' expected benefits ("gets") and contributions ("gives") needed to establish and maintain long-term, mutually advantageous community-academic partnerships. This article describes three case study experiences using the Give Get Grid in real-world context to understand and generate ideas to address contemporary health promotion opportunities among a variety of stakeholders. The case studies address three distinct community health promotion opportunities: prevention of school-based adolescent obesity disparities, higher education health professions training programs in rural community-based settings, and methods for engaging community coalitions in state Comprehensive Cancer Control Programs. The case studies demonstrate the Give-Get Grid's utility in both planning and evaluating partnerships and documenting key elements for progress in health promotion initiatives built on long-term community-academic relationships. Steps are explained with practical lessons learned in using the Grid. PMID- 29191082 TI - Scaling Up and Tailoring the "Putting Public Health in Action" Training Curriculum. AB - Despite access to a growing menu of evidence-based interventions, public health practitioners continue to underuse them, in part because practitioners may require new knowledge, skills, and resources to do so. Numerous foundations, universities, governmental agencies, and consultants are providing trainings to address the gaps in practitioners' capacity. To most significantly affect population health, these trainings need to reach practitioners who may have limited access to on-site trainings. Despite the number of organizations offering trainings, little is known about how to scale up trainings to efficiently extend their reach or how to tailor trainings to the needs of different intervention. The Cancer Prevention and Control Research Network and its collaborating centers have developed a training curriculum and delivered it in both in-person and distance formats to a range of audiences. The purpose of this article is to describe the training curriculum and findings from the Network's evaluation of approaches used to scale up delivery of the "Putting Public Health Evidence in Action" curriculum and tailor content for specific evidence-based interventions. PMID- 29191081 TI - Improving Linkage, Retention, and Reengagement in HIV Care in 12 Metropolitan Areas. AB - The Centers for Disease Control and Prevention developed the Enhanced Comprehensive HIV Prevention Planning (ECHPP) project to support 12 health departments' improvement of their HIV prevention and care portfolios in response to new national guidelines. We systematically analyzed 3 years of progress reports to learn how grantees put into practice local intervention strategies intended to link people to, and keep them in, HIV care. All grantees initiated seven activities to support these strategies: (1) improve surveillance data systems, (2) revise staffing duties and infrastructures, (3) update policies and procedures, (4) establish or strengthen partnerships, (5) identify persons not in care, (6) train personnel, and (7) create ways to overcome obstacles to receiving care. Factors supporting ECHPP grantee successes were thorough planning, attention to detail, and strong collaboration among health department units, and between the health department and external stakeholders. Other jurisdictions may consider adopting similar strategies when planning and enhancing HIV linkage, retention, and reengagement efforts in their areas. ECHPP experiences, lessons learned, and best practices may be relevant when applying new public health policies that affect community and health care practices jurisdiction-wide.

AB - In three studies, we examined the relationship between free will beliefs and job satisfaction over time and across cultures. Study 1 examined 252 Taiwanese real estate agents over a 3-months period. Study 2 examined job satisfaction for 137 American workers on an online labor market over a 6-months period. Study 3 extended to a large sample of 14,062 employees from 16 countries and examined country-level moderators. We found a consistent positive relationship between the belief in free will and job satisfaction. The relationship was above and beyond other agency constructs (Study 2), mediated by perceived autonomy (Studies 2-3), and stronger in countries with a higher national endorsement of the belief in free will (Study 3). We conclude that free-will beliefs predict outcomes over time and across cultures beyond other agency constructs. We call for more cross cultural and longitudinal studies examining free-will beliefs as predictors of real-life outcomes. PMID- 29191085 TI - Effects of eicosapentaenoic acid and docosahexaenoic acid on anxiety-like behavior in socially isolated rats. AB - The effects of fish oil for improving mental health have been reported. The present study was undertaken to compare the effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on anxiety-like behavior using a rat model. Experimental diets enriched in EPA or DHA as glycerides were prepared. Rats were exposed to social isolation stress and fed the experimental diet for 14 days. The results of behavioral tests revealed that rats fed the EPA-enriched diet exhibited less anxiety-like behavior than rats fed the control or DHA-enriched diets. Furthermore, EPA suppressed anxiety-like behavior only in socially isolated rats. The increase in EPA contents in the brain phospholipid fraction by feeding EPA-enriched diet was more significant than that of DHA by feeding DHA enriched diet. These results suggest that dietary EPA is more anxiolytic than DHA in rats exposed to social isolation stress and is effective in increasing EPA content in brain membranes. PMID- 29191086 TI - A modern purification method for volatile sesquiterpenes produced by recombinant Escherichia coli carrying terpene synthase genes. AB - Most volatile sesquiterpenes had been purified from plants using distillation and preparative gas chromatography, which is not applicable to many laboratories that do not possess a needed facility. Thus, this review focuses on a modern purification method for volatile sesquiterpenes using Escherichia coli cells that functionally express terpene synthase (Tps) genes. It was recently developed that recombinant E. coli cells carrying Tps genes were cultured in two-layer media (n octane/TB medium) without harming the cells, and the volatile hydrophobic compounds trapped in the n-octane were purified by two-phase partition (alkane/alkaline 50% MeOH), silica gel column chromatography, and reversed-phase preparative high-performance liquid chromatography (if necessary). Consequently, it was found that the volatile sesquiterpenes are easily purified, the structures of which can then be determined by nuclear magnetic resonance, [alpha]D and gas chromatography-mass spectrometry analyses. The antioxidant activities of several volatile sesquiterpenes are also presented in this review. PMID- 29191087 TI - Neuroprotective effect of formononetin in ameliorating learning and memory impairment in mouse model of Alzheimer's disease. AB - Alzheimer's disease (AD) is the most common cause of dementia among elderly population. Deranged beta-amyloid (Abeta) trafficking across the blood-brain barrier is known to be a critical element in the pathogenesis of AD. In the vascular endothelial cells of hippocampus, Abeta transport is mainly mediated by low-density lipoprotein-associated protein 1 (LRP1) and the receptor for advanced glycation end (RAGE) products; therefore, LRP1 and RAGE endothelial cells are potential therapeutic targets for AD. In this study, we explored the effects of Formononetin (FMN) on learning and memory improvement in APP/PS1 mice and the related mechanisms. We found that FMN significantly improved learning and memory ability by suppressing Abeta production from APP processing, RAGE-dependent inflammatory signaling and promoted LRP1-dependent cerebral Abeta clearance pathway. Moreover, FMN treatment alleviated ultrastructural changes in hippocampal vascular endothelial cells. In conclusion, we believe that FMN may be an efficacious and promising treatment for AD. PMID- 29191088 TI - The delaying effect of alpha-glycerophosphocholine on senescence, transthyretin deposition, and osteoarthritis in senescence-accelerated mouse prone 8 mice. AB - Administration of alpha-glycerophosphocholine (GPC), a choline compound in food, is expected to contribute to human health. In this study, we evaluated its effect on aging in senescence-accelerated mouse prone 8 (SAMP8) mice. Male SAMP8 mice had free access to a commercial stock diet and drinking water with or without GPC (0.07 mg/ml). Mice in the GPC group had significantly lower total senescence grading score than that of the control group at 36 weeks of age. Administration of GPC decreased the deposition of transthyretin (TTR), an amyloidogenic protein, in the brain. Aggregated TTR activated microglia and led to neuroinflammation. Thus, GPC would protect the brain by reducing TTR deposition and preventing neuroinflammation. In a histological study of knee joints, it was found that SAMP8 mice administered GPC showed decreased joint degeneration. These results suggest that GPC delays the aging process and may be a useful compound in anti aging functional food development. PMID- 29191089 TI - Purification and characterization of small and large rubber particles from Hevea brasiliensis. AB - Natural rubber (NR) is synthesized by the rubber transferase (RTase) on rubber particles (RPs) in latex. Due to the heterogeneity of the RPs in latex, it is difficult to precisely characterize the RTase activity. In this study, we separated the RPs of Hevea brasiliensis with different particle size distributions, via stepwise centrifugations. Analyses of protein compositions and size distributions of NR in the RPs suggest that RPs in Hevea latex can be categorized into two distinct subclasses, the larger RPs (termed 1kRP, 2kRP, and 8kRP) and the smaller RPs (termed 20kRP and 50kRP). Precise enzymatic assays using the RPs revealed that 50kRP showed the highest RTase activity, whereas the larger RPs, which had been regarded to have quite low activity, also exhibited a comparable activity to the smaller RPs. Immunological detections of cis prenyltransferases in the RPs showed that the abundance of these enzymes correlates with the extent of RTase activity. PMID- 29191091 TI - Schizosaccharomyces japonicus has low levels of CoQ10 synthesis, respiration deficiency, and efficient ethanol production. AB - Coenzyme Q (CoQ) is essential for mitochondrial respiration and as a cofactor for sulfide quinone reductase. Schizosaccharomyces pombe produces a human-type CoQ10. Here, we analyzed CoQ in other fission yeast species. S. cryophilus and S. octosporus produce CoQ9. S. japonicus produces low levels of CoQ10, although all necessary genes for CoQ synthesis have been identified in its genome. We expressed three genes (dps1, dlp1, and ppt1) for CoQ synthesis from S. japonicus in the corresponding S. pombe mutants, and confirmed that they were functional. S. japonicus had very low levels of oxygen consumption and was essentially respiration defective, probably due to mitochondrial dysfunction. S. japonicus grows well on minimal medium during anaerobic culture, indicating that it acquires sufficient energy by fermentation. S. japonicus produces comparable levels of ethanol under both normal and elevated temperature (42 degrees C) conditions, at which S. pombe is not able to grow. PMID- 29191090 TI - Alterations in circadian and meal-induced gut peptide levels in lean and obese rats. AB - Alterations in gut hormone signaling are a likely contributing factor to the metabolic disturbances associated with overweight/obesity as they coordinate the timing of feeding behavior, absorption, and utilization of nutrients. These hormones are released in response to food intake, or follow a circadian or anticipatory pattern of secretion that is independent of nutrient stimulation. The aim of this study was to identify the degree to which high-fat diet-induced obesity would alter the daily rhythm of gut peptide plasma levels (glucagon-like peptide-1 [GLP-1], peptide YY [PYY], insulin or amylin [AMY]) or meal-induced levels in the middle of the light or dark cycle. Male Sprague-Dawley rats were fed a high-fat diet (OBESE) or chow (LEAN), implanted with jugular catheters, and blood samples were taken every 2 h throughout the light/dark cycle while freely feeding or after an Ensure liquid meal. We found that even when OBESE and LEAN animals ate the same kcals and have a similar pattern of food intake, there is a difference in both the levels and rhythm of plasma gut peptides. GLP-1 and PYY are higher during the light cycle in LEAN animals and AMY is higher in the OBESE group throughout the light/dark cycle. There was also a differential response of plasma gut signals after the Ensure meal, even though the composition and amount of intake of the meal were the same in both groups. These changes occur prior to the high-fat diet induced loss of glycemic control and may be a target for early intervention. Impact statement The aim of this study was to test if obesity would alter the daily rhythm of gut peptides or meal-induced levels in the middle of the light or dark cycle. We found that even when animals are eating the same amount (in kcal) of food that the obese animals have altered daily rhythms and meal-induced gut peptide levels. In particular, we are the first to show that obesity induces increases in peptide YY levels during the light cycle and amylin remains high throughout the light and dark cycle in obese animals. These changes occurred prior to a loss of glycemic control. Thus, the rhythm of gut peptides could be used as an early indicator of later and more serious metabolic disturbances and may be a target for early intervention. PMID- 29191092 TI - Plant-derived isoprenoid sweeteners: recent progress in biosynthetic gene discovery and perspectives on microbial production. AB - Increased public awareness of negative health effects associated with excess sugar consumption has triggered increasing interest in plant-derived natural sweeteners. Steviol glycosides are a group of highly sweet diterpene glycosides contained in the leaves of stevia (Stevia rebaudiana). Mogrosides, extracted from monk fruit (Siraitia grosvenorii), are a group of cucurbitane-type triterpenoid glycosides. Glycyrrhizin is an oleanane-type triterpenoid glycoside derived from the underground parts of Glycyrrhiza plants (licorice). This review focuses on the natural isoprenoid sweetening agents steviol glycosides, mogrosides, and glycyrrhizin, and describes recent progress in gene discovery and elucidation of the catalytic functions of their biosynthetic enzymes. Recently, remarkable progress has been made in engineering the production of various plant-specialized metabolites in microbial hosts such as Saccharomyces cerevisiae via the introduction of biosynthetic enzyme genes. Perspectives on the microbial production of plant-derived natural sweeteners are also discussed. PMID- 29191093 TI - Branched-chain amino acids regulate type I tropocollagen and type III tropocollagen syntheses via modulation of mTOR in the skin. AB - Branched-chain amino acids (BCAAs) exhibit many physiological functions. However, the potential link and mechanism between BCAA and skin function are unknown. We examined the effects of deletion of branched-chain alpha-keto acid dehydrogenase kinase (BDK), a key enzyme in BCAA catabolism, on type I and III tropocollagen syntheses in mice. Leucine and isoleucine levels were significantly lower in the skin of BDK-KO mice compared with wild-type mice. No changes in valine concentrations were observed. The levels of type I and III tropocollagen proteins and mRNAs (COL1A1 and COL3A1) were significantly lower in the skin of BDK-KO mice compared with wild-type mice. The phosphorylation of p70 S6 kinase, which indicates mammalian target of rapamycin (mTOR) activation, was reduced in the skin of BDK-KO mice compared with wild-type mice. These findings suggest that deficiencies of leucine and isoleucine reduce type I and III tropocollagen syntheses in skin by suppressing the action of mTOR. PMID- 29191094 TI - Potential of predictive computer models for preoperative patient selection to enhance overall quality-adjusted life years gained at 2-year follow-up: a simulation in 234 patients with adult spinal deformity. AB - OBJECTIVE Patients with adult spinal deformity (ASD) experience significant quality of life improvements after surgery. Treatment, however, is expensive and complication rates are high. Predictive analytics has the potential to use many variables to make accurate predictions in large data sets. A validated minimum clinically important difference (MCID) model has the potential to assist in patient selection, thereby improving outcomes and, potentially, cost effectiveness. METHODS The present study was a retrospective analysis of a multiinstitutional database of patients with ASD. Inclusion criteria were as follows: age >= 18 years, radiographic evidence of ASD, 2-year follow-up, and preoperative Oswestry Disability Index (ODI) > 15. Forty-six variables were used for model training: demographic data, radiographic parameters, surgical variables, and results on the health-related quality of life questionnaire. Patients were grouped as reaching a 2-year ODI MCID (+MCID) or not (-MCID). An ensemble of 5 different bootstrapped decision trees was constructed using the C5.0 algorithm. Internal validation was performed via 70:30 data split for training/testing. Model accuracy and area under the curve (AUC) were calculated. The mean quality-adjusted life years (QALYs) and QALYs gained at 2 years were calculated and discounted at 3.5% per year. The QALYs were compared between patients in the +MCID and -MCID groups. RESULTS A total of 234 patients met inclusion criteria (+MCID 129, -MCID 105). Sixty-nine patients (29.5%) were included for model testing. Predicted versus actual results were 50 versus 40 for +MCID and 19 versus 29 for -MCID (i.e., 10 patients were misclassified). Model accuracy was 85.5%, with 0.96 AUC. Predicted results showed that patients in the +MCID group had significantly greater 2-year mean QALYs (p = 0.0057) and QALYs gained (p = 0.0002). CONCLUSIONS A successful model with 85.5% accuracy and 0.96 AUC was constructed to predict which patients would reach ODI MCID. The patients in the +MCID group had significantly higher mean 2-year QALYs and QALYs gained. This study provides proof of concept for using predictive modeling techniques to optimize patient selection in complex spine surgery. PMID- 29191095 TI - Male sex may not be associated with worse outcomes in primary all-posterior adult spinal deformity surgery: a multicenter analysis. AB - OBJECTIVE Adolescent spine deformity studies have shown that male patients require longer surgery and have greater estimated blood loss (EBL) and complications compared with female patients. No studies exist to support this relationship in adult spinal deformity (ASD). The purpose of this study was to investigate associations between sex and complications, deformity correction, and health-related quality of life (HRQOL) in patients with ASD. It was hypothesized that male ASD patients would have greater EBL, longer surgery, and more complications than female ASD patients. METHODS A multicenter ASD cohort was retrospectively queried for patients who underwent primary posterior-only instrumented fusions with a minimum of 5 levels fused. The minimum follow-up was 2 years. Primary outcomes were EBL, operative time, intra-, peri-, and postoperative complications, radiographic correction, and HRQOL outcomes (Oswestry Disability Index, SF-36, and Scoliosis Research Society-22r Questionnaire). Poisson multivariate regression was used to control for age, comorbidities, and levels fused. RESULTS Ninety male and 319 female patients met the inclusion criteria. Male patients had significantly greater mean EBL (2373 ml vs 1829 ml, p = 0.01). The mean operative time, transfusion requirements, and final radiographic measurements did not differ between sexes. Similarly, changes in HRQOL showed no significant differences. Finally, there were no sex differences in the incidence of complications (total, major, or minor) at any time point after controlling for age, body mass index, comorbidities, and levels fused. CONCLUSIONS Despite higher EBL, male ASD patients did not experience more complications or require less deformity correction at the 2-year follow-up. HRQOL scores similarly showed no sex differences. These findings differ from adolescent deformity studies, and surgeons can counsel patients that sex is unlikely to influence the outcomes and complication rates of primary all-posterior ASD surgery. PMID- 29191096 TI - Lumbar computed tomography scans are not appropriate surrogates for bone mineral density scans in primary adult spinal deformity. AB - OBJECTIVE The authors examined the correlation between lumbar spine CT Hounsfield unit (HU) measurements and bone mineral density measurements in an adult spinal deformity (ASD) population. METHODS Patients with ASD were identified in the records of a single institution. Lumbar CT scans were reviewed, and the mean HU measurements from L1-4 were recorded. Bone mineral density (BMD) was assessed using femoral neck and lumbar spine dual-energy x-ray absorptiometry (DEXA). The number of patients who met criteria for osteoporosis was determined for each imaging modality. RESULTS Forty-eight patients underwent both preoperative DEXA and CT scanning. Forty-three patients were female and 5 were male. Forty-seven patients were Caucasian and one was African American. The mean age of the patients was 62.1 years. Femoral neck DEXA was more likely to identify osteopenia (n = 26) than lumbar spine DEXA (n = 8) or lumbar CT HU measurements (n = 6) (p < 0.001). There was a low-moderate correlation between lumbar spine CT and lumbar spine DEXA (r = 0.463, p < 0.001), and there was poor correlation between lumbar spine CT and femoral neck DEXA (r = 0.303, p = 0.036). CONCLUSIONS Despite the opportunistic utility of lumbar spine CT HU measurements in identifying osteoporosis in patients undergoing single-level fusion, these measurements were not useful in this cohort of ASD patients. The correlation between femoral neck DEXA and HU measurements was poor. DEXA assessment of BMD in ASD patients is essential to optimize the care of these complicated cases. PMID- 29191097 TI - Introduction. Adult spinal deformity. PMID- 29191098 TI - Complication rates associated with open versus percutaneous pedicle screw instrumentation among patients undergoing minimally invasive interbody fusion for adult spinal deformity. AB - OBJECTIVE High-quality studies that compare outcomes of open and minimally invasively placed pedicle screws for adult spinal deformity are needed. Therefore, the authors compared differences in complications from a circumferential minimally invasive spine (MIS) surgery and those from a hybrid surgery. METHODS A retrospective review of a multicenter database of patients with spinal deformity who were treated with an MIS surgery was performed. Database inclusion criteria included an age of >= 18 years and at least 1 of the following: a coronal Cobb angle of > 20 degrees , a sagittal vertical axis of > 5 cm, a pelvic incidence-lumbar lordosis angle of > 10 degrees , and/or a pelvic tilt of > 20 degrees . Patients were propensity matched according to the levels instrumented. RESULTS In this database, a complete data set was available for 165 patients, and after those who underwent 3-column osteotomy were excluded, 137 patients were available for analysis; 76 patients remained after propensity matching (MIS surgery group 38 patients, hybrid surgery group 38 patients). The authors found no difference in demographics, number of levels instrumented, or preoperative and postoperative radiographic results. At least 1 complication was suffered by 55.3% of patients in the hybrid surgery group and 44.7% of those in the MIS surgery group (p = 0.359). Patients in the MIS surgery group had significantly fewer neurological, operative, and minor complications than those in the hybrid surgery group. The reoperation rates in both groups were similar. The most common complication category for the MIS surgery group was radiographic and for the hybrid surgery group was neurological. Patients in both groups experienced postoperative improvement in their Oswestry Disability Index and visual analog scale (VAS) back and leg pain scores (all p < 0.05); however, MIS surgery provided a greater reduction in leg pain according to VAS scores. CONCLUSIONS Overall complication rates in the MIS and hybrid surgery groups were similar. MIS surgery resulted in significantly fewer neurological, operative, and minor complications. Reoperation rates in the 2 groups were similar, and despite complications, the patients reported significant improvement in their pain and function. PMID- 29191099 TI - An assessment of frailty as a tool for risk stratification in adult spinal deformity surgery. AB - OBJECTIVE The goal of this study was to analyze the value of an adult spinal deformity frailty index (ASD-FI) in preoperative risk stratification. Preoperative risk assessment is imperative before procedures known to have high complication rates, such as ASD surgery. Frailty has been associated with risk of complications in trauma surgery, and preoperative frailty assessments could improve the accuracy of risk stratification by providing a comprehensive analysis of patient factors that contribute to an increased risk of complications. METHODS Using 40 variables, the authors calculated frailty scores with a validated method for 417 patients (enrolled between 2010 and 2014) with a minimum 2-year follow-up in an ASD database. On the basis of these scores, the authors categorized patients as not frail (NF) (< 0.3 points), frail (0.3-0.5 points), or severely frail (SF) (> 0.5 points). The correlation between frailty category and incidence of complications was analyzed. RESULTS The overall mean ASD-FI score was 0.33 (range 0.0-0.8). Compared with NF patients (n = 183), frail patients (n = 158) and SF patients (n = 109) had longer mean hospital stays (1.2 and 1.6 times longer, respectively; p < 0.001). The adjusted odds of experiencing a major intraoperative or postoperative complication were higher for frail patients (OR 2.8) and SF patients ( 4.1) compared with NF patients (p < 0.01). For frail and SF patients, respectively, the adjusted odds of developing proximal junctional kyphosis (OR 2.8 and 3.1) were higher than those for NF patients. The SF patients had higher odds of developing pseudarthrosis (OR 13.0), deep wound infection (OR 8.0), and wound dehiscence (OR 13.4) than NF patients (p < 0.05), and they had 2.1 times greater odds of reoperation (p < 0.05). CONCLUSIONS Greater patient frailty, as measured by the ASD-FI, was associated with worse outcome in many common quality and value metrics, including greater risk of major complications, proximal junctional kyphosis, pseudarthrosis, deep wound infection, wound dehiscence, reoperation, and longer hospital stay. PMID- 29191100 TI - Preliminary results of anterior lumbar interbody fusion, anterior column realignment for the treatment of sagittal malalignment. AB - OBJECTIVE Sagittal malalignment decreases patients' quality of life and may require surgical correction to achieve realignment goals. High-risk posterior based osteotomy techniques are the current standard treatment for addressing sagittal malalignment. More recently, anterior lumbar interbody fusion, anterior column realignment (ALIF ACR) has been introduced as an alternative for correction of sagittal deformity. The objective of this paper was to report clinical and radiographic results for patients treated using the ALIF-ACR technique. METHODS A retrospective study of 39 patients treated with ALIF ACR was performed. Patient demographics, operative details, radiographic parameters, neurological assessments, outcome measures, and preoperative, postoperative, and mean 1-year follow-up complications were studied. RESULTS The patient population comprised 39 patients (27 females and 12 males) with a mean follow-up of 13.3 +/- 4.7 months, mean age of 66.1 +/- 11.6 years, and mean body mass index of 27.3 +/- 6.2 kg/m2. The mean number of ALIF levels treated was 1.5 +/- 0.5. Thirty-three (84.6%) of 39 patients underwent posterior spinal fixation and 33 (84.6%) of 39 underwent posterior column osteotomy, of which 20 (60.6%) of 33 procedures were performed at the level of the ALIF ACR. Pelvic tilt, sacral slope, and pelvic incidence were not statistically significantly different between the preoperative and postoperative periods and between the preoperative and 1-year follow-up periods (except for PT between the preoperative and 1-year follow-up, p = 0.018). Sagittal vertical axis, T-1 spinopelvic inclination, lumbar lordosis, pelvic incidence-lumbar lordosis mismatch, intradiscal angle, and motion segment angle all improved from the preoperative to postoperative period and the preoperative to 1-year follow-up (p < 0.05). The changes in motion segment angle and intradiscal angle achieved in the ALIF-ACR group without osteotomy compared with the ALIF-ACR group with osteotomy at the level of ACR were not statistically significant. Total visual analog score, Oswestry Disability Index, and Scoliosis Research Society-22 scores all improved from preoperative to postoperative and preoperative to 1-year follow-up. Fourteen patients (35.9%) experienced 26 complications (15 major and 11 minor). Eleven patients required reoperation. The most common complication was proximal junctional kyphosis (6/26 complications, 23%) followed by vertebral body/endplate fracture (3/26, 12%). CONCLUSIONS This study showed satisfactory radiographic and clinical outcomes at the 1-year follow up. Proximal junctional kyphosis was the most common complication followed by fracture, complications that are commonly associated with sagittal realignment surgery and may not be mitigated by the anterior approach. PMID- 29191101 TI - Despite worse baseline status depressed patients achieved outcomes similar to those in nondepressed patients after surgery for cervical deformity. AB - OBJECTIVE Depression and anxiety have been demonstrated to have negative impacts on outcomes after spine surgery. In patients with cervical deformity (CD), the psychological and physiological burdens of the disease may overlap without clear boundaries. While surgery has a proven record of bringing about significant pain relief and decreased disability, the impact of depression and anxiety on recovery from cervical deformity corrective surgery has not been previously reported on in the literature. The purpose of the present study was to determine the effect of depression and anxiety on patients' recovery from and improvement after CD surgery. METHODS The authors conducted a retrospective review of a prospective, multicenter CD database. Patients with a history of clinical depression, in addition to those with current self-reported anxiety or depression, were defined as depressed (D group). The D group was compared with nondepressed patients (ND group) with a similar baseline deformity determined by propensity score matching of the cervical sagittal vertical axis (cSVA). Baseline demographic, comorbidity, clinical, and radiographic data were compared among patients using t-tests. Improvement of symptoms was recorded at 3 months, 6 months, and 1 year postoperatively. All health-related quality of life (HRQOL) scores collected at these follow-up time points were compared using t-tests. RESULTS Sixty-six patients were matched for baseline radiographic parameters: 33 with a history of depression and/or current depression, and 33 without. Depressed patients had similar age, sex, race, and radiographic alignment: cSVA, T-1 slope minus C2-7 lordosis, SVA, and T-1 pelvic angle (p > 0.05). Compared with nondepressed individuals, depressed patients had a higher incidence of osteoporosis (21.2% vs 3.2%, p = 0.028), rheumatoid arthritis (18.2% vs 3.2%, p = 0.012), and connective tissue disorders (18.2% vs 3.2%, p = 0.012). At baseline, the D group had greater neck pain (7.9 of 10 vs 6.6 on a Numeric Rating Scale [NRS], p = 0.015), lower mean EQ-5D scores (68.9 vs 74.7, p < 0.001), but similar Neck Disability Index (NDI) scores (57.5 vs 49.9, p = 0.063) and myelopathy scores (13.4 vs 13.9, p = 0.546). Surgeries performed in either group were similar in terms of number of levels fused, osteotomies performed, and correction achieved (baseline to 3-month measurements) (p < 0.05). At 3 months, EQ-5D scores remained lower in the D group (74.0 vs 78.2, p = 0.044), and NDI scores were similar (48.5 vs 39.0, p = 0.053). However, neck pain improved in the D group (NRS score of 5.0 vs 4.3, p = 0.331), and modified Japanese Orthopaedic Association (mJOA) scores remained similar (14.2 vs 15.0, p = 0.211). At 6 months and 1 year, all HRQOL scores were similar between the 2 cohorts. One-year measurements were as follows: NDI 39.7 vs 40.7 (p = 0.878), NRS neck pain score of 4.1 vs 5.0 (p = 0.326), EQ-5D score of 77.1 vs 78.2 (p = 0.646), and mJOA score of 14.0 vs 14.2 (p = 0.835). Anxiety/depression levels reported on the EQ-5D scale were significantly higher in the depressed cohort at baseline, 3 months, and 6 months (all p < 0.05), but were similar between groups at 1 year postoperatively (1.72 vs 1.53, p = 0.416). CONCLUSIONS Clinical depression was observed in many of the study patients with CD. After matching for baseline deformity, depression symptomology resulted in worse baseline EQ-5D and pain scores. Despite these baseline differences, both cohorts achieved similar results in all HRQOL assessments 6 months and 1 year postoperatively, demonstrating no clinical impact of depression on recovery up until 1 year after CD surgery. Thus, a history of depression does not appear to have an impact on recovery from CD surgery.

AB - OBJECTIVE The aim of this study was to educate medical professionals about potential financial impacts of improper diagnosis-related group (DRG) coding in adult spinal deformity (ASD) surgery. METHODS Medicare's Inpatient Prospective Payment System PC Pricer database was used to collect 2015 reimbursement data for ASD procedures from 12 hospitals. Case type, hospital type/location, number of operative levels, proper coding, length of stay, and complications/comorbidities (CCs) were analyzed for effects on reimbursement. DRGs were used to categorize cases into 3 types: 1) anterior or posterior only fusion, 2) anterior fusion with posterior percutaneous fixation with no dorsal fusion, and 3) combined anterior and posterior fixation and fusion. RESULTS Pooling institutions, cases were reimbursed the same for single-level and multilevel ASD surgery. Longer stay, from 3 to 8 days, resulted in an additional $1400 per stay. Posterior fusion was an additional $6588, while CCs increased reimbursement by approximately $13,000. Academic institutions received higher reimbursement than private institutions, i.e., approximately $14,000 (Case Types 1 and 2) and approximately $16,000 (Case Type 3). Urban institutions received higher reimbursement than suburban institutions, i.e., approximately $3000 (Case Types 1 and 2) and approximately $3500 (Case Type 3). Longer stay, from 3 to 8 days, increased reimbursement between $208 and $494 for private institutions and between $1397 and $1879 for academic institutions per stay. CONCLUSIONS Reimbursement is based on many factors not controlled by surgeons or hospitals, but proper DRG coding can significantly impact the financial health of hospitals and availability of quality patient care. PMID- 29191103 TI - Relative lumbar lordosis and lordosis distribution index: individualized pelvic incidence-based proportional parameters that quantify lumbar lordosis more precisely than the concept of pelvic incidence minus lumbar lordosis. AB - OBJECTIVE The subtraction of lumbar lordosis (LL) from the pelvic incidence (PI) offers an estimate of the LL required for a given PI value. Relative LL (RLL) and the lordosis distribution index (LDI) are PI-based individualized measures. RLL quantifies the magnitude of lordosis relative to the ideal lordosis as defined by the magnitude of PI. LDI defines the magnitude of lower arc lordosis in proportion to total lordosis. The aim of this study was to compare RLL and PI - LL for their ability to predict postoperative complications and their correlations with health-related quality of life (HRQOL) scores. METHODS Inclusion criteria were >= 4 levels of fusion and >= 2 years of follow-up. Mechanical complications were proximal junctional kyphosis/proximal junctional failure, distal junctional kyphosis/distal junctional failure, rod breakage, and implant-related complications. Correlations between PI - LL, RLL, PI, and HRQOL were analyzed using the Pearson correlation coefficient. Mechanical complication rates in PI - LL, RLL, LDI, RLL, and LDI interpreted together, and RLL subgroups for each PI - LL category were compared using chi-square tests and the exact test. Predictive models for mechanical complications with RLL and PI - LL were analyzed using binomial logistic regressions. RESULTS Two hundred twenty-two patients (168 women, 54 men) were included. The mean age was 52.2 +/- 19.3 years (range 18-84 years). The mean follow-up was 28.8 +/- 8.2 months (range 24-62 months). There was a significant correlation between PI - LL and PI (r = 0.441, p < 0.001), threatening the use of PI - LL to quantify spinopelvic mismatch for different PI values. RLL was not correlated with PI (r = -0.093, p > 0.05); therefore, it was able to quantify divergence from ideal lordosis for all PI values. Compared with PI - LL, RLL had stronger correlations with HRQOL scores (p < 0.05). Discrimination performance was better for the model with RLL than for PI - LL. The agreement between RLL and PI - LL was high (kappa = 0.943, p < 0.001), moderate (kappa = 0.455, p < 0.001), and poor (kappa = -0.154, p = 0.343), respectively, for large, average, and small PI sizes. When analyzed by RLL, each PI - LL category was further divided into distinct groups of patients who had different mechanical complication rates (p < 0.001). CONCLUSIONS Using the formula of PI - LL may be insufficient to quantify normolordosis for the whole spectrum of PI values when applied as an absolute numeric value in conjunction with previously reported population-based average thresholds of 10 degrees and 20 degrees . Schwab PI - LL groups were found to constitute an inhomogeneous group of patients. RLL offers an individualized quantification of LL for all PI sizes. Compared with PI - LL, RLL showed a greater association with both mechanical complications and HRQOL. The use of RLL and LDI together, instead of PI - LL, for surgical planning may result in lower mechanical complication rates and better long-term HRQOL. PMID- 29191104 TI - Does prior spine surgery or instrumentation affect surgical outcomes following 3 column osteotomy for correction of thoracolumbar deformities? AB - OBJECTIVE Adult spinal deformity (ASD) develops in the setting of asymmetrical arthritic degeneration, and can also be due to iatrogenic causes, such as prior surgery. Many patients who present with ASD have undergone prior spine surgery with instrumentation. Unfortunately, contemporary studies that evaluate the effect of prior surgery or instrumentation on perioperative outcomes, readmission rates, and need for reoperation are lacking. METHODS All ASD patients who underwent a 3-column osteotomy performed by the senior author at the authors' institution for correction of thoracolumbar spinal deformity between 2006 and 2016 were identified. The authors compared surgical outcomes between primary (first-time) and revision cases. Further subgroup analysis was conducted to investigate the effect of the number of prior surgeries (0, 1, 2, 3, 4, and 5 or more) and the presence of spinal instrumentation on outcomes. Multivariate analysis was used to adjust for relevant and significant confounders. RESULTS A total of 300 patients were included; 38.3% of patients were male. The overall perioperative complication rate was 24.7%, and the mean length of hospitalization was 8.2 days. The 90-day readmission rate was 9.0%, and the overall follow-up reoperation rate was 26.7%. There were no significant differences in complication rates (26.6% vs 24.0%, p = 0.645), length of hospitalization (8.7 vs 7.9 days, p = 0.229), readmission rates (11.4% vs 8.1%, p = 0.387), or reoperation rates (26.6% vs 26.7%, p = 0.984) between primary and revision cases. There was no significant difference in wound complications (infections/dehiscence) requiring reoperation (5.1% vs 6.3%, p = 0.683). Subgroup analysis conducted to evaluate the effect of the number of prior spinal surgeries or the presence of spinal instrumentation did not reveal significant differences for the aforementioned surgical outcomes. In adjusted multivariate analysis, there were no significant associations between history of prior surgery (number of prior surgeries and prior instrumentation) and all of the surgical outcomes of interest. CONCLUSIONS The findings from this study suggest that patients who have undergone prior spine surgery with or without instrumentation are not at increased risk for perioperative complications, need for readmission, or reoperation following 3 column osteotomy of the thoracolumbar spine.

AB - Certain dioxins, including 2,3,7,8,-tetrachloro-dibenzo-p-dioxin (TCDD), are exogenous ligands for an aryl hydrocarbon receptor (AhR) and induces various drug metabolizing enzymes. In this study, we examined the effect of curcumin on expression of drug-metabolizing enzymes through the AhR and NF-E2 related factor 2 (Nrf2) pathways. Curcumin dose-dependently inhibited TCDD-induced expression of phase I enzyme cytochrome P450 1A1 (CYP1A1) and phase II enzymes NAD(P)H:quinone oxidoreductase-1 (NQO1) and heme oxygenase 1 (HO-1) but not tert-butyl hydroquinone-induced NQO1 and HO-1, suggesting that curcumin inhibited only AhR pathway, but not Nrf2 one directly. Furthermore, we used 14 curcumin derivatives and obtained the correlation between hydrophobicity of the compounds and suppressive effect against AhR transformation. Results from the quantitative structure active correlative analysis indicated that methoxy groups and beta diketone structure possessing keto-enol tautomerism in curcumin were necessary to inhibit AhR transformation, and the addition of methyl and methoxy group(s) to the curcumin increased the inhibition effect. PMID- 29191106 TI - Suppression of phenotype of Escherichia coli mutant defective in farnesyl diphosphate synthase by overexpression of gene for octaprenyl diphosphate synthase. AB - We investigated suppression of the slow growth of an Escherichia coli ispA null mutant lacking farnesyl diphosphate (FPP) synthase (i.e. IspA) by plasmids carrying prenyl diphosphate synthase genes. The growth rates of ispA mutant transformants harboring a medium-copy number plasmid that carries ispA or ispB were almost the same as that of the wild-type strain. Although the level of FPP in the transformant with the ispA plasmid was almost the same as that in the wild type strain, the level in the transformant with the ispB plasmid was as low as that in the ispA mutant. Purified octaprenyl diphosphate synthase (IspB) could condense isopentenyl diphosphate (IPP) with dimethylallyl diphosphate (DMAPP) to form octaprenyl diphosphate and nonaprenyl diphosphate. It is possible that suppression of the slow growth of the ispA mutant by ispB was due to condensation of IPP not only with FPP but also with DMAPP by octaprenyl diphosphate synthase. PMID- 29191107 TI - Not All Skepticism Is Equal: Exploring the Ideological Antecedents of Science Acceptance and Rejection. AB - Many topics that scientists investigate speak to people's ideological worldviews. We report three studies-including an analysis of large-scale survey data-in which we systematically investigate the ideological antecedents of general faith in science and willingness to support science, as well as of science skepticism of climate change, vaccination, and genetic modification (GM). The main predictors are religiosity and political orientation, morality, and science understanding. Overall, science understanding is associated with vaccine and GM food acceptance, but not climate change acceptance. Importantly, different ideological predictors are related to the acceptance of different scientific findings. Political conservatism best predicts climate change skepticism. Religiosity, alongside moral purity concerns, best predicts vaccination skepticism. GM food skepticism is not fueled by religious or political ideology. Finally, religious conservatives consistently display a low faith in science and an unwillingness to support science. Thus, science acceptance and rejection have different ideological roots, depending on the topic of investigation.

AB - The objective of this study was to determine falls risk profiles to derive a falls risk prediction score and establish a simple and practical clinical screening tool for Chinese community-dwelling elderly individuals. This was a prospective cohort study (n = 619) among adults aged 60 years and older. Falls were ascertained at a 1-year follow-up appointment. Sociodemographic information, medical history, and physical performance data were collected. The mean age was 67.4 years; 57.7% were women. Female sex (odds ratios [ORs] 1.82; 95% confidence interval [95% CI] 1.17-2.82), diabetes (OR 2.13; 95% CI 1.13-3.98), a Timed Up and Go Test (TUGT) >=10.49 seconds (OR 1.51; 95% CI 1.23-1.94), a history of falls (OR 3.15; 95% CI 1.72-5.79), and depression (Geriatric Depression Scale [GDS] >=11, OR 2.51; 95% CI 1.36-4.63) were the strongest predictors. These predictors were used to establish a risk score. The area under the curve of the score was 0.748. From a clinical point of view, the most appropriate cutoff value was 7 (97.5% specificity, 70.7% positive predictive value, and 83.6% negative predictive value). For this cutoff, the fraction correctly classified was 82.5%. A cutoff score of 7 derived from a risk assessment tool using four risk factors (gender, falls history, diabetes, and depression) and the TUGT may be used in Chinese community-dwelling elderly individuals as an initial step to screen those at low risk for falls. PMID- 29191109 TI - Utilization of an intermediate of the methylerythritol phosphate pathway, (E)-4 hydroxy-3-methylbut-2-en-1-yl diphosphate, as the prenyl donor substrate for various prenyltransferases. AB - (E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate (HMBPP) is an intermediate of the methylerythritol phosphate pathway. Utilization of HMBPP by lycopene elongase from Corynebacterium glutamicum, which is a UbiA-family prenyltransferase responsible for C50 carotenoid biosynthesis, was investigated using an Escherichia coli strain that contained the exogenous mevalonate pathway as well as the carotenoid biosynthetic pathway. Inhibition of the endogenous methylerythritol phosphate pathway resulted in loss of the production of C50 carotenoid flavuxanthin, while C40 lycopene formation was retained. Overexpression of E. coli ispH gene, which encodes HMBPP reductase, also decreased the production of flavuxanthin in E. coli cells. These results indicate the preference of lycopene elongase for HMBPP instead of the previously proposed substrate, dimethylallyl diphosphate. Furthermore, several (all-E)-prenyl diphosphate synthases, which are classified in a distinct family of prenyltransferase, were demonstrated to accept HMBPP, which implies that the compound is more widely used as a prenyl donor substrate than was previously expected. PMID- 29191110 TI - Decennial trends and inequalities in healthy life expectancy: The HUNT Study, Norway. AB - AIMS: Norway is experiencing a rising life expectancy combined with an increasing dependency ratio - the ratio of those outside over those within the working force. To provide data relevant for future health policy we wanted to study trends in total and healthy life expectancy in a Norwegian population over three decades (1980s, 1990s and 2000s), both overall and across gender and educational groups. METHODS: Data were obtained from the HUNT Study, and the Norwegian Educational Database. We calculated total life expectancy and used the Sullivan method to calculate healthy life expectancies based on self-rated health and self reported longstanding limiting illness. The change in health expectancies was decomposed into mortality and disability effects. RESULTS: During three consecutive decades we found an increase in life expectancy for 30-year-olds (~7 years) and expected lifetime in self-rated good health (~6 years), but time without longstanding limiting illness increased less (1.5 years). Women could expect to live longer than men, but the extra life years for females were spent in poor self-rated health and with longstanding limiting illness. Differences in total life expectancy between educational groups decreased, whereas differences in expected lifetime in self-rated good health and lifetime without longstanding limiting illness increased. CONCLUSIONS: The increase in total life expectancy was accompanied by an increasing number of years spent in good self-rated health but more years with longstanding limiting illness. This suggests increasing health care needs for people with chronic diseases, given an increasing number of elderly. Socioeconomic health inequalities remain a challenge for increasing pensioning age. PMID- 29191112 TI - Attitude Accessibility as a Function of Emotionality. AB - Despite the centrality of both attitude accessibility and attitude basis to the last 30 years of theoretical and empirical work concerning attitudes, little work has systematically investigated their relation. The research that does exist provides conflicting results and is not at all conclusive given the methodology that has been used. The current research uses recent advances in statistical modeling and attitude measurement to provide the most systematic examination of the relation between attitude accessibility and basis to date. Specifically, we use mixed-effects modeling which accounts for variation across individuals and attitude objects in conjunction with the Evaluative Lexicon (EL)-a linguistic approach that allows for the simultaneous measurement of an attitude's valence, extremity, and emotionality. We demonstrate across four studies, over 10,000 attitudes, and nearly 50 attitude objects that attitudes based on emotion tend to be more accessible in memory, particularly if the attitude is positive.

AB - This paper explores two key norms that underpin intimate partner violence in Rwanda: men's roles as economic providers and decision-making authorities in the household. It describes the political, legal and socio-economic factors affecting these norms and how they create opportunities and barriers to 'undoing' restrictive gender norms. Findings are drawn from an evaluation of Inadshyikirwa, an intimate partner violence prevention programme operating in Rwanda. Across three intervention sectors, 24 focus groups were conducted with unmarried and married men and women residing in intervention communities. Thirty interviews with couples and nine interviews with opinion leaders were conducted before they completed programme training designed to shift gender norms underlying intimate partner violence. The data indicate a strong awareness of and accountability to Rwandan laws and policies supporting women's economic empowerment and decision making, alongside persisting traditional notions of men as household heads and primary breadwinners. Transgression of these norms could be accommodated in some circumstances, especially those involving economic necessity. The data also identified increasing recognition of the value of a more equitable partnership model. Findings highlight the importance of carefully assessing cracks in the existing gender order that can be exploited to support gender equality and non violence.

AB - The hypO gene from Sinorhizobium meliloti, located within the trans-4-hydroxy-L proline metabolic gene cluster, was first successfully expressed in the host Pseudomonas putida. Purified HypO protein functioned as a FAD-containing cis-4 hydroxy-D-proline dehydrogenase with a homomeric structure. In contrast to other known enzymes, significant activity for D-proline was found, confirming a previously proposed potential involvement in D-proline metabolism. PMID- 29191114 TI - Gene CG15630 (fipi) is involved in regulation of the interpulse interval in Drosophila courtship song. AB - To study the central pattern generators functioning, previously we identified genes, whose neurospecific knockdowns led to deviations in the courtship song of Drosophila melanogaster males. Reduced expression of the gene CG15630 caused a decrease in the interpulse interval. To investigate the role of CG15630, which we have called here fipi (factor of interpulse interval), in the courtship song production, at first, we have characterized fipi transcripts and protein (FIPI) in the mutant flies carrying P insertion and deletions in this gene and in flies with its RNAi knockdown. FIPI is homologous to the mammalian NCAM2 protein, an important factor of neuronal development in the olfactory system. In this study, we have revealed that local fipi knockdown in the antennal olfactory sensory neurons (OR67d and IR84a), which are responsible for reception of chemosignals modulating courtship behavior, alters the interpulse interval in the opposite directions. Thus, a proper fipi expression seems to be necessary for perception of sexual chemosignals, and the effect of fipi knockdown on IPI value depends on the type of chemoreceptor neurons affected.

PMID- 29191115 TI - Focal neurons: another source of vascular endothelial growth factor in brain arteriovenous malformation tissues? AB - Background Brain arteriovenous malformations (bAVMs) are devastating, hemorrhage prone, cerebrovascular entities characterized by well-defined feeding arteries, draining veins, and the absence of a capillary bed. The endothelial cells that comprise bAVMs exhibit a loss of arterial and venous specification. The role of abnormal angiogenesis in the formation and progression of bAVMs is still unclear. This study aimed to investigate the expression of vascular endothelial growth factor (VEGF) in neurons and glial cells in bAVMs to try to uncover the multiple cell origin of VEGF. Methods A total of 25 bAVM specimens and 25 control tissues were obtained. Western blot and immunohistochemical analyses were used to evaluate the expression of VEGF. The distribution of VEGF in neurons and glial cells in these bAVMs were observed by double-label immunofluorescence staining and subsequent imaging. Results Western blot analysis revealed a significant overexpression of VEGF in bAVM tissues (P < 0.05). Immunohistochemistry showed that the amount of cells that overexpressed VEGF in bAVM tissues was significantly greater compared to that in normal tissues (P < 0.05). Double-label immunofluorescence staining showed no significant difference between the mean amounts of VEGF-positive cells in astrocytes and in neurons (P < 0.05). Conclusions The formation and progression of bAVMs is related to the local overexpression of VEGF. Similar levels of VEGF overexpression are found in astrocytes, neurons, and vascular endothelial cells, which suggest that VEGF may be derived from astrocytes and neurons. It implied that focal neurons may play a certain role in the pathophysical process of bAVMs, however, identification of the production and functional mechanisms of VEGF in the neurons still requires further investigation.

AB - AIM OF THE STUDY: Thiopurines are effective drugs in treating neuromyelitis optica spectrum disorders and other diseases. Thiopurines' toxicity is mainly imputed to thiopurine S-methyltransferase activity. In Chinese population, the most common and important variation of thiopurine S-methyltransferase is TPMT*3C (rs1142345). This study aims to reveal the association between thiopurine S methyltransferase activity and genetic polymorphisms of thiopurine S methyltransferase in patients with neuromyelitis optica spectrum disorders in China. MATERIAL AND METHODS: A liquid chromatography tandem mass/mass method was used to evaluate the thiopurine S-methyltransferase activity by using 6 mercapthioprine as the substrate in human erythrocyte haemolysate via 1 h incubation at 37 degrees C to form its methylated product 6 methylmercaptopurine. The amount of 6-methylmercaptopurine was adjusted by haematocrit and normalized to 8 * 108 erythrocytes. The selected polymorphisms of thiopurine S-methyltransferase were identified using MassARRAY system (Sequenom) and multiple SNaPshot technique. RESULTS: In 69 patients with neuromyelitis optica spectrum disorders, thiopurine S-methyltransferase activity was 80.29 154.53 (127.51 +/- 16.83) pmol/h/8 * 108 erythrocytes. TPMT*3C (rs1142345) was associated with lower thiopurine S-methyltransferase activity (BETA = -25.37, P = 0.011). Other selected variants were not associated with thiopurine S methyltransferase activity. CONCLUSIONS: TPMT*3C affects TPMT activity in Chinese patients with neuromyelitis optica spectrum disorders. Further studies are warranted to confirm the results.

In the early years, general surgeons training in the United States would spend post-residency time abroad learning from surgical masters in Europe and other places. Since Harvey Cushing's day, neurosurgeons from around the world continue to travel abroad, with many now coming to America for training at centers of excellence. Current clinical practice is defined by multi-national, multi-center clinical trials, and the AANS subsidiary NeuroPoint Alliance has positioned itself to serve as an international center for the oversight of such trials. The Neurosurgery Research & Education Foundation and the Journal of Neurosurgery Publishing Group have made it possible for a neurosurgeon anywhere with Internet access to learn relevant surgical anatomy, learn new neurosurgical procedures, and watch masters in the field perform operations via high-definition surgical videos at no cost via learning platforms such as the Rhoton Collection, the Neurosurgical Atlas, and Neurosurgical Focus video supplements. At the same time, patients are now traveling abroad to seek medical specialty care. Although the globalization of health care poses certain threats, it also presents neurosurgeons with a world of opportunities. PMID- 29191123 TI - Patient Perceptions of Barriers to Self-Management of Breast Cancer-Related Lymphedema. AB - Breast cancer survivors are at lifetime risk for the development of breast cancer related lymphedema, a chronic, potentially debilitating condition that requires life-long symptom management. Suboptimal self-management rates suggest that health care providers may not be offering educative-support options that are customized to patient-perceived needs. An Institutional Review Board-approved focus group ( N = 9) and mailed surveys ( N = 15) were used to identify (a) barriers to lymphedema self-management, (b) how breast cancer survivors with lymphedema defined education and support, (c) what type of education and support they had received, and (d) what kind of education and support they wanted. Physiological, psychological, and psychosocial factors were identified as barriers to successful lymphedema self-management. One of the main barriers identified was lack of education about lymphedema treatment and risk reduction. In addition, more than half defined support as "prescriptions" and "referrals"; therefore, it is unclear whether patients were exposed to support other than medical treatment.

AB - INTRODUCTION: Non-muscle invasive bladder cancer (NMIBC) is a highly recurrent disease with potential progression to muscle invasive disease despite the standard bladder instillations with mitomycin C (MMC) or Bacille Calmette-Guerin immunotherapy. Therefore, alternatives such as radiofrequency-induced chemohyperthermia (RF-CHT) with MMC are being investigated. The mechanism explaining the efficacy of RF-CHT is only partly understood. We examined whether RF-CHT results in higher MMC tissue concentrations as compared to cold MMC instillation. PATIENTS AND METHODS: Prior to a planned transurethral resection of bladder tumour (TURBT), patients with stage Ta NMIBC were allocated to either (1) cold MMC instillation or (2) RF-CHT. After MMC instillation, three biopsies were taken of both normal and tumour tissue. Biopsies were snap-frozen and MMC tissue concentrations were analysed using ultra-performance liquid chromatography. RESULTS: Eleven patients were included of which six received RF-CHT. Ten patients had TaG2-LG/HG papillary tumours at pathology. One patient in the RF-CHT group appeared to be free of malignancy and was excluded from the analysis as no tumour biopsies were available. The median MMC concentration in tumour tissue was higher in the RF-CHT group (median 665.00 ng/g vs. 63.75 ng/g, U = 51.0, p = 0.018). Moreover, in both techniques the MMC concentration was lower in normal tissue compared to tumour tissue. Tissue MMC concentration measurements varied substantially within, and between, different patients from the same group. CONCLUSION: Intravesical RF-CHT results in higher tumour MMC concentrations vs. cold MMC instillation which contributes to its superior efficacy. PMID- 29191127 TI - The association between the environmental endocrine disruptor bisphenol A and polycystic ovary syndrome: a systematic review and meta-analysis. AB - OBJECTIVE: To investigate the association between bisphenol A (BPA) and polycystic ovary syndrome (PCOS). METHODS: A systematic review and meta-analysis using STATA software for observational studies. RESULTS: Nine studies involving 493 PCOS patients and 440 controls were included in this review. The meta analysis demonstrated that PCOS patients had significantly higher BPA levels compared with control groups (standardized mean difference (SMD): 2.437, 95% confidence interval (CI): (1.265, 3.609), p < .001). For studies of serum samples detected by enzyme-linked immunosorbent assay (ELISA), subgroup analyses according to ethnicity, body mass index (BMI), sample size, detection method (high-performance liquid chromatography (HPLC) and ELISA), PCOS-to-control ratio and study quality displayed that high BPA levels were significantly associated with Caucasian PCOS patients (SMD: 0.615, 95% CI: (0.308, 0.922), p < .001), high BMI (SMD: 0.512, 95% CI: (0.180, 0.843), p = .002), high quality (SMD: 0.624, 95% CI: (0.391, 0.856), p < .001), and high HOMA-IR (SMD: 0.467, 95% CI: (0.121, 0.813), p = .008). CONCLUSIONS: Serum BPA may be positively associated with women with PCOS and BPA might be involved in the insulin-resistance and hyperandrogenism of PCOS. More evidence from high quality studies, advanced detection methods, and larger cohorts for observational trials are needed to further confirm the association between BPA and PCOS.

AB - Inhibition of excessive fructose intake in the small intestine could alleviate fructose-induced diseases such as hypertension and non-alcoholic fatty liver disease. We examined the effect of phytochemicals on fructose uptake using human intestinal epithelial-like Caco-2 cells which express the fructose transporter, GLUT5. Among 35 phytochemicals tested, five, including nobiletin and epicatechin gallate (ECg), markedly inhibited fructose uptake. Nobiletin and ECg also inhibited the uptake of glucose but not of L-leucine or Gly-Sar, suggesting an inhibitory effect specific to monosaccharide transporters. Kinetic analysis further suggested that this reduction in fructose uptake was associated with a decrease in the apparent number of cell-surface GLUT5 molecules, and not with a change in the affinity of GLUT5 for fructose. Lastly, nobiletin and ECg suppressed the permeation of fructose across Caco-2 cell monolayers. These findings suggest that nobiletin and ECg are good candidates for preventing diseases caused by excessive fructose intake. PMID- 29191129 TI - Subcellular localization of aphidicolin biosynthetic enzymes heterologously expressed in Aspergillus oryzae. AB - The secondary metabolite aphidicolin has previously been produced by Aspergillus oryzae after the heterologous expression of four biosynthetic enzymes isolated from Phoma betae. In this study, we examined the subcellular localization of aphidicolin biosynthetic enzymes in A. oryzae. Fusion of green fluorescent protein to each enzyme showed that geranylgeranyl diphosphate synthase and terpene cyclase are localized to the cytoplasm and the two monooxygenases (PbP450 1 and PbP450-2) are localized to the endoplasmic reticulum (ER). Protease protection assays revealed that the catalytic domain of both PbP450s was cytoplasmic. Deletion of transmembrane domains from both PbP450s resulted in the loss of ER localization. Particularly, a PbP450-1 mutant lacking the transmembrane domain was localized to dot-like structures, but did not colocalize with any known organelle markers. Aphidicolin biosynthesis was nearly abrogated by deletion of the transmembrane domain from PbP450-1. These results suggest that ER localization of PbP450-1 is important for aphidicolin biosynthesis.

AB - There are many reports about carotenoid-producing bacteria and carotenoid biosynthesis genes. In databases for Pseudomonas genome sequences, there are genes homologous to carotenoid biosynthesis genes, but the function of these genes in Pseudomonas has not been elucidated. In this study, we cloned the carotenoid biosynthesis genes from a Pseudomonas sp. strain, named Akiakane, which was isolated from the excrement of the Autumn Darter dragonfly. Using an Escherichia coli functional expression system, we confirmed that the idi, crtE, crtB, crtI, and crtY gene products of the Akiakane strain show predictable catalytic activities. A cluster of six genes was also found, which was comparable to other carotenoid-producing bacteria that belong to the alpha-Proteobacteria or gamma-Proteobacteria class. PMID- 29191131 TI - Efficacy of ceftazidime-avibactam in a rat intra-abdominal abscess model against a ceftazidime- and meropenem-resistant isolate of Klebsiella pneumoniae carrying blaKPC-2. AB - Efficacies of ceftazidime-avibactam (4:1 w/w) and ceftazidime were tested against ceftazidime-susceptible (blaKPC-2-negative), and meropenem- and ceftazidime resistant (blaKPC-2-positive), Klebsiella pneumoniae in a 52-h, multiple dose, abdominal abscess model in the rat. Efficacies corresponded to minimum inhibitory concentrations (MICs) measured in vitro and were consistent with drug exposures modelled from pharmacokinetics in infected animals. The ceftazidime, ceftazidime avibactam and meropenem control treatments were effective in the rat abscess model against the susceptible strain, whereas only ceftazidime-avibactam was effective against K. pneumoniae harbouring blaKPC-2. PMID- 29191132 TI - Severe Disseminated Necrotizing and Granulomatous Lymphadenitis and Encephalitis in a Dog Due to Sporotrichum pruinosum (Teleomorph: Phanerochaete chrysosporium). AB - A 9-year-old female mixed breed dog presented for an acute onset of anorexia, vomiting, and cough. Initial examination and diagnostics revealed a large multilobular cranial mediastinal mass with unidentified fungal organisms on cytology. The disease progressed in spite of therapy until the dog was euthanized 8 months later. Gross necropsy findings were a large multilobular intrathoracic mass, mild pleuritis, and generalized lymphadenopathy. Histologic evaluation showed granulomatous inflammation and necrosis with numerous 20- to 70-micron, periodic acid-Schiff- and Gomori methenamine silver-positive spherules effacing lymph node parenchyma, as well as severe inflammation within the midbrain. Endosporulation was a common finding, and large numbers of fungal hyphae were also present in affected areas. Ribosomal RNA gene sequencing found 100% identity to published sequences of Phanerochaete chrysosporium, the teleomorph form of Sporotrichum pruinosum. This is the first published report of disease caused by natural infection with this basidiomycete organism in animals. PMID- 29191133 TI - Focal Segmental Glomerulosclerosis in Related Miniature Schnauzer Dogs. AB - Focal segmental glomerulosclerosis (FSGS) recently has been recognized as a common cause of proteinuria in dogs in general, and in Miniature Schnauzer dogs in particular. This study describes the morphologic features present in the kidneys of 8 related proteinuric Miniature Schnauzer dogs. The FSGS, characterized by solidification of portions of the capillary tuft, affected 32% to 49% of examined glomeruli in these dogs. Synechiae, often accompanied by hyalinosis, were present in 13% to 54% of glomeruli and were more prevalent in older dogs. Seven of 8 dogs had arteriolar hyalinosis. Ultrastructurally, all dogs had evidence of a podocytopathy in the absence of electron-dense deposits, glomerular basement membrane splitting, or fibrils. All dogs had multifocal to extensive podocyte foot process effacement. Other podocyte changes included microvillous transformation, the presence of vacuoles or protein resorption droplets, cytoplasmic electron-dense aggregates, and occasional binucleation. Variable amounts of intraglomerular lipid were present in all dogs. All dogs were proteinuric, with measured values for the urine protein-to-creatinine ratio ranging from 1.2 to 6.5. Azotemia was mild to absent and dogs were euthanatized at 5.1 to 14 years of age, in all cases due to nonrenal diseases. The underlying cause of FSGS in these Miniature Schnauzer dogs has yet to be determined, but contributors likely include genetic podocytopathy, lipid abnormalities, and glomerular hypertension. PMID- 29191135 TI - Message Framing and Engagement in Specialty Mental Health Care. AB - OBJECTIVE: Engagement rates in specialty mental health care for depression are suboptimal. This study examined the extent to which framing-by gain, by loss, or neutral- of health messages promotes appointment attendance among patients referred to specialty mental health care. METHODS: The study employed a randomized, prospective, experimental design. Patients meeting criteria for major depression and referred to specialty mental health care at the Corporal Michael J. Crescenz Department of Veterans Affairs Medical Center were randomly assigned (N=360) to receive a patient reminder letter routinely mailed prior to scheduled specialty care appointments (neutral) or one of two messages (gain framed versus loss framed) that were added to the routine letter. Appointment and attendance data were extracted from the computerized system. Logistic regression was used to determine the association between message frame condition and initial appointment attendance. RESULTS: The sample (mean+/-SD age=51.5+/-13.5) was primarily male (85%) and nonwhite (62%), and the mean depressive symptom score indicated moderately severe depression. Participants who received the gain-framed message after being referred to specialty mental health care were significantly more likely to attend their appointment than those who received a neutral letter (p=.04). No statistically significant differences were noted among those receiving a loss-framed message compared with the other two arms. CONCLUSIONS: Findings suggest that highlighting the benefits of attending an initial specialty mental health care appointment, even if in writing, can affect engagement rates. If replicated, results have the potential to improve mental health treatment initiation rates in a timely, efficient, and cost-effective manner. PMID- 29191134 TI - Safety Evaluation of Lipid Nanoparticle-Formulated Modified mRNA in the Sprague Dawley Rat and Cynomolgus Monkey. AB - The pharmacology, pharmacokinetics, and safety of modified mRNA formulated in lipid nanoparticles (LNPs) were evaluated after repeat intravenous infusion to rats and monkeys. In both species, modified mRNA encoding the protein for human erythropoietin (hEPO) had predictable and consistent pharmacologic and toxicologic effects. Pharmacokinetic analysis conducted following the first dose showed that measured hEPO levels were maximal at 6 hours after the end of intravenous infusion and in excess of 100-fold the anticipated efficacious exposure (17.6 ng/ml) at the highest dose tested.24 hEPO was pharmacologically active in both the rat and the monkey, as indicated by a significant increase in red blood cell mass parameters. The primary safety-related findings were caused by the exaggerated pharmacology of hEPO and included increased hematopoiesis in the liver, spleen, and bone marrow (rats) and minimal hemorrhage in the heart (monkeys). Additional primary safety-related findings in the rat included mildly increased white blood cell counts, changes in the coagulation parameters at all doses, as well as liver injury and release of interferon gamma-inducible protein 10 in high-dose groups only. In the monkey, as seen with the parenteral administration of cationic LNPs, splenic necrosis and lymphocyte depletion were observed, accompanied with mild and reversible complement activation. These findings defined a well-tolerated dose level above the anticipated efficacious dose. Overall, these combined studies indicate that LNP-formulated modified mRNA can be administered by intravenous infusion in 2 toxicologically relevant test species and generate supratherapeutic levels of protein (hEPO) in vivo. PMID- 29191136 TI - Use of a Mental Health Center Collaborative Care Team to Improve Diabetes Care and Outcomes for Patients With Psychosis. AB - OBJECTIVE: This study aimed to evaluate the feasibility, acceptability, and preliminary effectiveness (compared with usual care) of a collaborative care model to treat community mental health center (CMHC) patients with psychosis and poorly controlled diabetes. METHODS: Stakeholder input was used to adapt a primary care-based collaborative care intervention for CMHC settings. Thirty-five adult CMHC clients with type II diabetes and hemoglobin A1c (HbA1c) >8% or blood pressure >140/90 were randomized to receive either collaborative care or usual care. Change in HbA1c was evaluated between baseline and three months. Paired t tests were used for within-group comparisons. RESULTS: After three months, intervention participants had a statistically significant mean decrease in HbA1c of 1.1% (p=.049). There was no significant change in HbA1c in the usual-care group. CONCLUSIONS: This pilot demonstrates the feasibility and acceptability of implementing collaborative care in CMHC settings and its preliminary effectiveness in improving glycemic control in a high-risk population. PMID- 29191137 TI - Racial-Ethnic Differences in Patterns of Discontinuous Medication Treatment Among Medicaid-Insured Youths With ADHD. AB - OBJECTIVE: This study examined the association between race-ethnicity and patterns of medication gaps and discontinuities among Medicaid-insured children initiating pharmacotherapy for attention-deficit hyperactivity disorder (ADHD). METHODS: Medicaid claims data from nine states were used to identify racial ethnic differences in patterns of ADHD medication treatment among 102,669 children initiating ADHD medication. Multinomial logistic regression with state indicators was used to estimate these differences, with adjustment for individual and contextual confounders. RESULTS: Approximately three-fifths of the sample did not receive continuous medication treatment as defined by HEDIS guidelines; among them, one-fifth discontinued treatment with no subsequent reinitiation (early termination), less than one-tenth reinitiated pharmacotherapy following a single medication gap, more than three-tenths experienced discontinuous pharmacotherapy with two gaps, and more than four-tenths experienced discontinuous pharmacotherapy with three or more gaps. Compared with white children, black children had a 25% relative increase in the likelihood of early termination and Hispanic children had a 21% relative increase (p<.001); their relative increases in the likelihood of two medication gaps were 41% and 29%, respectively (p<.001), and for three or more gaps they were 56% and 40%, respectively (p<.001). CONCLUSIONS: Black and Hispanic children were much more likely than white children to be classified as discontinuing ADHD medication treatment, according to HEDIS. The differences predominantly occurred because youths from minority groups were more likely to experience multiple medication gaps, rather than complete discontinuation. Future studies should examine reasons for these multiple gaps to inform interventions to improve ADHD treatment continuity. PMID- 29191138 TI - Differential Reimbursement of Psychiatric Services by Psychiatrists and Other Medical Providers. AB - OBJECTIVE: Given low psychiatrist participation in insurance networks, this study examines how psychiatrists are reimbursed in network and out of network under commercial insurance relative to other providers for the same diagnoses and services. METHODS: Paid private insurance claims from the 2014 Truven Health Analytics MarketScan Commercial Claims and Encounters Database were analyzed. The sample included all services billed for 3.8 million individuals with a mental disorder as the primary diagnosis by psychiatrists, nonpsychiatrist medical doctors, psychologists, social workers, or psychiatric nurses. The authors determined the most common services provided by each provider type, the median reimbursement and median out-of-pocket payment for the services by provider type and by network status (in or out of network), and the proportion of bills for services delivered out of network. RESULTS: "Evaluation and management" services for presenting problems of low to moderate and moderate to high severity were the two procedures most frequently billed by psychiatrists and nonpsychiatrist medical doctors. The median reimbursement for services for presenting problems of low to moderate and moderate to high severity was 13% less ($66 versus $76) and 20% less ($91 versus $114), respectively, for psychiatrists versus nonpsychiatrist medical doctors if the services were provided in network but 28% higher ($100 versus $78) and 6% higher ($122 versus $115), respectively, for psychiatrists versus nonpsychiatrist medical doctors for services provided out of network. CONCLUSIONS: Psychiatrists receive lower in-network reimbursement than nonpsychiatrist medical doctors for many of the same services. This may contribute to psychiatrists' lower participation in insurance networks relative to other providers and has implications for patient cost sharing and access to psychiatrists. PMID- 29191139 TI - Potential Benefits to Patients and Payers From Increased Measurement of Antipsychotic Plasma Levels in the Management of Schizophrenia. AB - Approximately 40% of patients with schizophrenia either do not respond to the prescribed antipsychotic drug or cannot tolerate it because of side effects, resulting in poor disease control and negative health and economic outcomes. Identifying the root cause of such complicated courses of treatment is a critical step in the treatment of these patients. Although measurement of antipsychotic plasma levels can be used to discern potential root causes, this tool is not routinely used in the United States. The authors of this column discuss the potential effects on patient outcomes and on the value of care from greater use of this diagnostic tool, especially under emerging payment models and delivery system reform efforts. PMID- 29191140 TI - Management of Common Medical Conditions by Office-Based Psychiatrists. AB - OBJECTIVE: This study examined the extent of psychiatrists' involvement in general medical management activities for their patients. METHODS: With data from the 2006-2013 U.S. National Ambulatory Medical Survey-an annual cross-sectional survey of visits in a random week to office-based physicians-general medical management activities in 11,046 visits to psychiatrists, 66,267 to general medical physicians (general and family physicians and internists), and 158,933 to other physicians were compared. General medical management activities included recordings of hypertension, hyperlipidemia, diabetes, or obesity; prescriptions of medications for hypertension, hyperlipidemia, or diabetes; blood pressure or weight measurements; ordering glucose, glycohemoglobin (HbA1c), lipids, or cholesterol laboratory tests; and education or counseling for weight, exercise, diet and nutrition, or tobacco use. RESULTS: Any of the target general medical management activities were provided in 37.0% of visits to psychiatrists, compared with 98.0% of visits to general medical physicians and 78.4% to other physicians. Differences between psychiatrists and all other physician groups were smaller for health education and counseling. For each general medical management activity, many of the psychiatrists did not engage in the activity in any of their sampled visits. The most consistent predictors of general medical management activities in each psychiatrist visit were the extent of these activities in other visits to the same psychiatrist and having recorded other types of general medical management activities in the same visit. CONCLUSIONS: Efforts to expand psychiatric practice to general medical management activities require better understanding of barriers to such expansion, better characterization of conditions under which such expansion is feasible, and continuing medication education. PMID- 29191141 TI - Person-Oriented Recovery of Individuals With Serious Mental Illnesses: A Review and Meta-Analysis of Longitudinal Findings. AB - OBJECTIVE: Although there is significant literature examining changes over time in the functional recovery of people with serious mental illnesses, relatively little is known about the longitudinal nature of person-oriented recovery. The purpose of this review and meta-analysis is to synthesize findings pertaining to the study of person-oriented recovery constructs over time and concomitants of change. METHODS: Systematic searches up to February 2017 were conducted and were supplemented by hand-searching of reference lists and by contacting study authors. Twenty-three independent studies that included a sample of individuals with serious mental illnesses and that quantitatively measured person-oriented recovery, empowerment, or hope over at least two time points were included in the review. Of these, seven were randomized controlled trials that were included in the meta-analysis. Data were independently extracted by two reviewers. Aggregate effect sizes for person-oriented recovery outcomes were calculated, and individual, intervention, and methodological characteristics served as moderators in meta-regression analyses. RESULTS: The meta-analysis (N=1,739 participants) demonstrated that consumers experience greater (and sustained) improvement in person-oriented recovery outcomes when they are involved in recovery-oriented mental health treatment versus usual care or other types of treatment. Only type of intervention provider was a significant moderator; a study of an intervention that was delivered by both mental health professionals and peer providers demonstrated the greatest differences between treatment and control groups. CONCLUSIONS: Recovery-focused interventions, especially those that involve collaborations between mental health professionals and peer providers, may serve to foster increased recovery, hope, and empowerment among individuals with serious mental illnesses. PMID- 29191142 TI - Forensic Experts, Indigent Defendants, and the Constitution. AB - Over 30 years ago, the U.S. Supreme Court held that indigent defendants raising psychiatric issues are entitled to the assistance of a mental health expert. However, the exact dimensions of that assistance, and whether the expert must be assigned exclusively to assist the defense, have been in contention ever since. In its recent decision in McWilliams v. Dunn, the Court underscored that the state-funded expert must be available to consult with the defense, not merely to evaluate the defendant, but declined to opine on whether the defense is entitled to its own expert for the purpose. PMID- 29191143 TI - A crude sword bean (Canavalia gladiata) extract is gelated by cooling. AB - White sword bean (Canavalia gladiata) seeds have the potential to be utilized in the manufacturing of processed foods owing to their high protein and carbohydrate content. Our previous reports explored the use of the sword bean as a source of food materials by preparing extracts in distilled water. In the present study, we found that one such extract can be gelated by cooling. The gelling substances were extracted by boiling and simultaneously stirring a suspension containing ground beans. Few proteins were present in the gelated extract. We also examined the conditions under which gelation occurred and the gel melting temperature. The extract gelated at temperatures below 10 degrees C, and the resulting gel melted at those above 65 degrees C. This is the first report that gelling substances can be extracted from sword beans in large quantities. We expect that this gelling agent can be used for the production of processed foods.

AB - This column describes the development, implementation, and outcomes of a quality improvement learning collaborative that aimed to better integrate chaplaincy with mental health care services at 14 participating health care facilities evenly distributed across the U.S. Department of Veterans Affairs and Department of Defense. Teams of health care chaplains and mental health professionals from participating sites sought to improve cross-disciplinary service integration in six key domains: screening, referrals, assessment, communication and documentation, cross-disciplinary training, and role clarification. Chaplains and mental health providers across all facilities at participating sites were significantly more likely post-collaboration to report having a clear understanding of how to collaborate and to report using a routine process for screening patients who could benefit from seeing a professional from the other discipline. Foundational efforts to enhance cross-disciplinary awareness and screening practices between chaplains and mental health professionals appear particularly promising.

AB - Social factors have not been sufficiently explored in municipal solid waste management studies. Latin America has produced even fewer studies with this approach; technical and economic investigations have prevailed. We explored the impacts of socioeconomic factors on municipal solid waste generation in Greater Sao Paulo, which includes 39 municipalities. We investigated the relations between municipal solid waste generation and social factors by Pearson's correlation coefficient. The Student's t-test (at p <- 0.01) proved significance, and further regression analysis was performed with significant factors. We considered 10 socioeconomic factors: population, rural population, density, life expectancy, education (secondary, high and undergraduate level), income per capita, inequality and human development. A later multicollinearity analysis resulted in the determination of inequality (rp = 0.625) and income per capita (rp = 0.607) as major drivers. The results showed the relevance of considering social aspects in municipal solid waste management and isolated inequality as an important factor in planning. Inequality must be used as a complementary factor to income, rather than being used exclusively. Inequality may explain differences of waste generation between areas with similar incomes because of consumption patterns. Therefore, unequal realities demand unequal measures to avoid exacerbation, for example, pay-as-you-throw policies instead of uniform fees. Unequal realities also highlight the importance of tiering policies beyond the waste sector, such as sustainable consumption. PMID- 29191153 TI - The effect of specially designed and managed occlusal devices on patient symptoms of tinnitus: A cohort study. AB - Objective Bioesthetic maxillary anterior guided orthoses (BMAGOs) were designed and adjusted to establish the mandibular location referred to as stable seated condylar position SSCP. This study demonstrates treatment efficacy of this device on tinnitus. Methods All patients had histories of temporomandibular disorder (TMD), head, neck and shoulder pain. Each patient wore the BMAGO at all times, eating, talking and sleeping with it functioning as a surrogate occlusion. Patients were seen every two weeks for adjustments. They were provided a self reporting numeric rating scale (NRS) beginning each visit. NRS scores ranged from 0 to 10, with 10 being the highest intensity pain for 12 TMD symptoms including tinnitus. Results A significant decrease of tinnitus symptoms (p<.001) were recorded for all effected patients by visit #12. Conclusions These findings firmly support symptomatic reduction of tinnitus. PMID- 29191154 TI - Hepatitis C testing and re-testing among people attending sexual health services in Australia, and hepatitis C incidence among people with human immunodeficiency virus: analysis of national sentinel surveillance data. AB - BACKGROUND: Direct acting antivirals are expected to drastically reduce the burden of hepatitis C virus (HCV) in people living with Human Immunodeficiency Virus (HIV). However, rates of HCV testing, re-testing and incident infection in this group remain uncertain in Australia. We assessed trends in HCV testing, re testing and incident infection among HIV-positive individuals, and evaluated factors associated with HCV re-testing and incident infection. METHODS: The study population consisted of HIV-positive individuals who visited a sexual health service involved in the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance (ACCESS) between 2007 and 2015. Poisson regression was used to assess trends and to evaluate factors associated with HCV re-testing and incident HCV infection. RESULTS: There were 9227 HIV-positive individuals included in our testing rate analysis. Of 3799 HIV-positive/HCV-negative people that attended an ACCESS sexual health service more than once, 2079 (54.7%) were re-tested for HCV and were therefore eligible for our incidence analysis. The rate of HCV testing increased from 17.1 to 51.4 tests per 100 patient years between 2007 and 2015 (p for trend <0.01). Over the same period, HCV re-testing rates increased from 23.9 to 79.7 tests per 100 person years (p for trend <0.01). A clear increase in testing and re-testing began after 2011. Patients who identified as men who have sex with men and those with a history of injecting drug use experienced high rates of HCV re-testing over the course of the study period. Among those who re-tested, 157 incident HCV infections occurred at a rate of 2.5 events per 100 person years. Between 2007 and 2009, 2010-2011, 2012-2013 and 2014-2015, rates of incident HCV were 0.8, 1.5, 3.9 and 2.7 events per 100 person years, respectively (p for trend <0.01). Incident HCV was strongly associated with a history of injecting drug use. CONCLUSIONS: High rates of HCV testing and re-testing among HIV-positive individuals in Australia will assist strategies to achieve HCV elimination through rapid treatment scale up. Continued monitoring of HCV incidence in this population is essential for guiding both HCV prevention and treatment strategies. PMID- 29191155 TI - Provider initiated tuberculosis case finding in outpatient departments of health care facilities in Ghana: yield by screening strategy and target group. AB - BACKGROUND: Meticulous identification and investigation of patients presenting with tuberculosis (TB) suggestive symptoms rarely happen in crowded outpatient departments (OPDs). Making health providers in OPDs diligently follow screening procedures may help increase TB case detection. From July 2010 to December 2013, two symptom based TB screening approaches of varying cough duration were used to screen and test for TB among general outpatients, PLHIV, diabetics and contacts in Accra, Ghana. METHODS: This study was a retrospective analysis comparing the yield of TB cases using two different screening approaches, allocated to selected public health facilities. In the first approach, the conventional 2 weeks cough duration with or without other TB suggestive symptoms was the criterion to test for TB in attendants of 7 general OPDs. In the second approach the screening criteria cough of >24 hours, as well as a history of at least one of the following symptoms: fever, weight loss and drenching night sweats were used to screen and test for TB among attendants of 3 general OPDs, 7 HIV clinics and 2 diabetes clinics. Contact investigation was initiated for index TB patients. The facilities documented the number of patients verbally screened, with presumptive TB, tested using smear microscopy and those diagnosed with TB in order to calculate the yield and number needed to screen (NNS) to find one TB case. Case notification trends in Accra were compared to those of a control area. RESULTS: In the approach using >24-hour cough, significantly more presumptive TB cases were identified among outpatients (0.82% versus 0.63%), more were tested (90.1% versus 86.7%), but less smear positive patients were identified among those tested (8.0% versus 9.4%). Overall, all forms of TB cases identified per 100,000 screened were significantly higher in the >24-hour cough approach at OPD (92.7 for cough >24 hour versus 82.7 for cough >2 weeks ), and even higher in diabetics (364), among contacts (693) and PLHIV (995). NNS (95% Confidence Interval) varied from 100 (93-109) for PLHIV, 144 (112-202) for contacts, 275 (197-451) for diabetics and 1144 (1101-1190) for OPD attendants. About 80% of the TB cases were detected in general OPDs. Despite the intervention, notifications trends were similar in the intervention and control areas. CONCLUSION: The >24-hour cough approach yielded more TB cases though required TB testing for a larger number of patients. The yield of TB cases per 100,000 population screened was highest among PLHIV, contacts, and diabetics, but the majority of cases were detected in general OPDs. The intervention had no discernible impact on general case notification. PMID- 29191156 TI - Pre-pregnancy BMI, gestational weight gain and risk of preeclampsia: a birth cohort study in Lanzhou, China. AB - BACKGROUND: To evaluate the independent and joint effects of maternal pre pregnancy BMI and gestational weight gain (GWG) on the risk of preeclampsia and its subtypes. METHODS: A birth cohort study was conducted from 2010 to 2012 in Lanzhou, China. Three hundred fourty seven pregnant women with preeclampsia and 9516 normotensive women at Gansu Provincial Maternity and Child Care Hospital were included in the present study. Unconditional logistic regression models were used to evaluate the associations between pre-pregnancy BMI, GWG, and risk of preeclampsia and its subtypes. RESULTS: Compared to women with normal pre pregnancy BMI, those who were overweight/obese had an increased risk of preeclampsia (OR = 1.81; 95%CI: 1.37-2.39). Women with excessive GWG had an increased risk of preeclampsia (OR = 2.28; 95%CI: 1.70-3.05) compared to women with adequate GWG. The observed increased risk was similar for mild-, severe- and late-onset preeclampsia. No association was found for early-onset preeclampsia. Overweight/obese women with excessive GWG had the highest risk of developing preeclampsia compared to normal weight women with no excessive weight gain (OR = 3.78; 95%CI: 2.65-5.41). CONCLUSIONS: Our results suggested that pre-pregnancy BMI and GWG are independent risk factors for preeclampsia and that the risk might vary by preeclampsia subtypes. Our study also proposed a potential synergistic effect of pre-pregnancy BMI and GWG that warrants further investigation. PMID- 29191157 TI - Genome-wide analysis of the Solanum tuberosum (potato) trehalose-6-phosphate synthase (TPS) gene family: evolution and differential expression during development and stress. AB - BACKGROUND: Trehalose-6-phosphate synthase (TPS) serves important functions in plant desiccation tolerance and response to environmental stimuli. At present, a comprehensive analysis, i.e. functional classification, molecular evolution, and expression patterns of this gene family are still lacking in Solanum tuberosum (potato). RESULTS: In this study, a comprehensive analysis of the TPS gene family was conducted in potato. A total of eight putative potato TPS genes (StTPSs) were identified by searching the latest potato genome sequence. The amino acid identity among eight StTPSs varied from 59.91 to 89.54%. Analysis of dN/dS ratios suggested that regions in the TPP (trehalose-6-phosphate phosphatase) domains evolved faster than the TPS domains. Although the sequence of the eight StTPSs showed high similarity (2571-2796 bp), their gene length is highly differentiated (3189-8406 bp). Many of the regulatory elements possibly related to phytohormones, abiotic stress and development were identified in different TPS genes. Based on the phylogenetic tree constructed using TPS genes of potato, and four other Solanaceae plants, TPS genes could be categorized into 6 distinct groups. Analysis revealed that purifying selection most likely played a major role during the evolution of this family. Amino acid changes detected in specific branches of the phylogenetic tree suggests relaxed constraints might have contributed to functional divergence among groups. Moreover, StTPSs were found to exhibit tissue and treatment specific expression patterns upon analysis of transcriptome data, and performing qRT-PCR. CONCLUSIONS: This study provides a reference for genome-wide identification of the potato TPS gene family and sets a framework for further functional studies of this important gene family in development and stress response. PMID- 29191158 TI - The miR172c-NNC1 module modulates root plastic development in response to salt in soybean. AB - BACKGROUND: Plant roots are highly plastic to high salinity. However, the molecular mechanism by which root developmental plasticity is regulated remains largely unknown. Previously we reported that miR172c-NNC1 module plays a key role in soybean-rhizobial symbiosis. The fact that the miR172c promoter contains several stress-related cis elements indicates that miR172c may have a role in root response to abiotic stress. RESULTS: Here we showed that miR172c is greatly induced by salt stress in soybean. Overexpression of miR172c and knockdown of miR172c activity resulted in substantially increased and reduced root sensitivity to salt stress, respectively. Furthermore, we show that the target gene NNC1 (Nodule Number Control 1) of miR172c was downregulated by salt stress. The transgenic roots overexpressing or knocking down NNC1 expression also exhibited the altered root sensitivity to salt stress. CONCLUSION: The study reveals the crucial role of miR172c-NNC1 module in root stress tolerance to salt stress in soybean. PMID- 29191159 TI - Barriers and facilitating factors related to use of early warning score among acute care nurses: a qualitative study. AB - BACKGROUND: The early warning score (EWS) was developed to identify deteriorating patients early. It is a track-and-trigger system based on vital signs designed to direct appropriate clinical responses based on the seriousness and nature of the underlying condition. Despite its wide dissemination, serious adverse events still occur, often due to failure among staff on general wards to follow the EWS protocol. The purpose of the study was to determine barriers and facilitating factors related to three aspects of the EWS protocol: 1) adherence to monitoring frequency, 2) call for junior doctors to patients with an elevated EWS, and 3) call for the medical emergency team. METHODS: Focus groups were conducted with nurses from medical and surgical acute care wards, and content analysis was used to identify barriers and facilitating factors in relation to the research questions. RESULTS: Adherence to monitoring frequency would frequently be set aside during busy periods for other tasks. Collaboration and communication with doctors about medical patients with elevated EWS was considered to be unrealistic due to the high number of patients with these scores. Collaboration with the medical emergency team was problematic, since many nurses found the team to have negative attitudes. CONCLUSION: EWS reduces complex clinical conditions to a single number, with the inherent risk to overlook clinical cues and subtle changes in patients' condition. The study showed that identifying and treating deteriorating patients is a collaborative task that requires diverse technical and non-technical skills for staff to perform optimally. PMID- 29191160 TI - The usefulness of the McGrath MAC laryngoscope in comparison with Airwayscope and Macintosh laryngoscope during routine nasotracheal intubation: a randomaized controlled trial. AB - BACKGROUND: McGrath MAC video laryngoscope offers excellent laryngosopic views and increases the success rate of orotracheal intubation in some cases. The aim of this study was to determine the usefulness of McGrath MAC for routine nasotracheal intubation by comparing McGrath MAC with Airway scope and Macintosh laryngoscope. METHODS: A total of 60 adult patients with ASA physical status class 1 or 2, aged 20-70 years were enrolled in this study. Patients were scheduled for elective oral surgery under general anesthesia with nasotracheal intubation. Exclusion criteria included lack of consent and expected difficult airway. Patients were randomly allocated to three groups: McGrath MAC (n = 20), Airway scope (n = 20), and Macintosh laryngoscope (n = 20). After induction, nasotracheal intubation was performed by six expert anesthesiologists with more than 6 years of experience. RESULTS: There were no significant differences in preoperative airway assessment among the three groups. Successful tracheal intubation time was 26.8 +/- 5.7 (mean +/- standard deviation) s for McGrath MAC, 36.4 +/- 11.0 s for Airway scope, and 36.5 +/- 8.9 s for Macintosh laryngoscope groups. The time for successful tracheal intubation for McGrath MAC group was significantly shorter than that for Airway scope and Macintosh laryngoscope (p < 0.01). McGrath MAC significantly improved the Cormack Lehane grade for nasotracheal intubation compared with Macintosh laryngoscope (p < 0.05). CONCLUSION: McGrath MAC significantly facilitates routine nasotracheal intubation compared with Airwayscope and Macintosh laryngoscope by shortening the tracheal intubation time and improving the Cormack Lehane grade. TRIAL REGISTRATION: UMINCTR Registration number UMIN000023506 . Registered 5 Aug 2016. PMID- 29191161 TI - Using Mechanical Turk to recruit participants for internet intervention research: experience from recruitment for four trials targeting hazardous alcohol consumption. AB - BACKGROUND: Mechanical Turk (MTurk) is an online portal operated by Amazon where 'requesters' (individuals or businesses) can submit jobs for 'workers.' MTurk is used extensively by academics as a quick and cheap means of collecting questionnaire data, including information on alcohol consumption, from a diverse sample of participants. We tested the feasibility of recruiting for alcohol Internet intervention trials through MTurk. METHODS: Participants, 18 years or older, who drank at least weekly were recruited for four intervention trials (combined sample size, N = 11,107). The same basic recruitment strategy was employed for each trial - invite participants to complete a survey about alcohol consumption (less than 15 min in length, US$1.50 payment), identify eligible participants who drank in a hazardous fashion, invite those eligible to complete a follow-up survey ($10 payment), randomize participants to be sent or not sent information to access an online intervention for hazardous alcohol use. Procedures where put in place to optimize the chances that participants could only complete the baseline survey once. RESULTS: There was a substantially slower rate of recruitment by the fourth trial compared to the earlier trials. Demographic characteristics also varied across trials (age, sex, employment and marital status). Patterns of alcohol consumption, while displaying some differences, did not appear to vary in a linear fashion between trials. CONCLUSIONS: It is possible to recruit large (but not inexhaustible) numbers of people who drink in a hazardous fashion. Issues for online intervention research when employing this sample are discussed. PMID- 29191162 TI - Severe congenital microcephaly with 16p13.11 microdeletion combined with NDE1 mutation, a case report and literature review. AB - BACKGROUND: Microcephaly is a disorder characterized by severe impairment in brain development, reduced brain and head size. Congenital severe microcephaly is very rare, and NDE1 deletion and genetic mutations are important contributors. CASE PRESENTATION: Single nucleotide polymorphism (SNP) chromosomal microarray analysis (CMA) and muation screening of NDE1 gene were performed in an 8-month patient with severe congenital microcephaly, and/or his parents. Genetic studies found a 16p13.11 deletion containing NDE1 gene, and a novel NDE1 mutation c.555_556GC > CT on the non-deleted homolog, inherited from his phenotypically normal parents, respectively. The 2 bp nucleotide change results in a missense mutation p.K185 N and a nonsense mutation p.Q186X. We also conducted literaturte review to compare the clinical phenotypes of our patient to those of cases previously reported with NDE1 mutations, and found all patients had mental retardation, severe microcephaly, and corpus callosum agenesis. CONCLUSION: This is the first Chinese reported with microcephaly caused by NDE1 mutations. NDE1 is a critical pathogenetic gene in severe congenital microcephaly. Sequencing NDE1 and CMA in patients with severe congenital microcephaly may be warranted. PMID- 29191163 TI - Antibiotic-resistant bacteria in the guts of insects feeding on plants: prospects for discovering plant-derived antibiotics. AB - BACKGROUND: Although plants produce many secondary metabolites, currently none of these are commercial antibiotics. Insects feeding on specific plants can harbour bacterial strains resistant to known antibiotics suggesting that compounds in the plant have stimulated resistance development. We sought to determine whether the occurrence of antibiotic-resistant bacteria in insect guts was a widespread phenomenon, and whether this could be used as a part of a strategy to identify antibacterial compounds from plants. RESULTS: Six insect/plant pairs were selected and the insect gut bacteria were identified and assessed for antibiotic susceptibilities compared with type strains from culture collections. We found that the gut strains could be more or less susceptible to antibiotics than the type strains, or show no differences. Evidence of antibacterial activity was found in the plant extracts from five of the six plants, and, in one case Catharanthus roseus (Madagascar Periwinkle), compounds with antibacterial activity were identified. CONCLUSION: Bacterial strains isolated from insect guts show a range of susceptibilities to antibiotics suggesting a complex interplay between species in the insect gut microbiome. Extracts from selected plants can show antibacterial activity but it is not easy to isolate and identify the active components. We found that vindoline, present in Madagascar Periwinkle extracts, possessed moderate antibacterial activity. We suggest that plant-derived antibiotics are a realistic possibility given the advances in genomic and metabolomic methodologies. PMID- 29191164 TI - Weighted likelihood inference of genomic autozygosity patterns in dense genotype data. AB - BACKGROUND: Genomic regions of autozygosity (ROA) arise when an individual is homozygous for haplotypes inherited identical-by-descent from ancestors shared by both parents. Over the past decade, they have gained importance for understanding evolutionary history and the genetic basis of complex diseases and traits. However, methods to infer ROA in dense genotype data have not evolved in step with advances in genome technology that now enable us to rapidly create large high-resolution genotype datasets, limiting our ability to investigate their constituent ROA patterns. METHODS: We report a weighted likelihood approach for inferring ROA in dense genotype data that accounts for autocorrelation among genotyped positions and the possibilities of unobserved mutation and recombination events, and variability in the confidence of individual genotype calls in whole genome sequence (WGS) data. RESULTS: Forward-time genetic simulations under two demographic scenarios that reflect situations where inbreeding and its effect on fitness are of interest suggest this approach is better powered than existing state-of-the-art methods to infer ROA at marker densities consistent with WGS and popular microarray genotyping platforms used in human and non-human studies. Moreover, we present evidence that suggests this approach is able to distinguish ROA arising via consanguinity from ROA arising via endogamy. Using subsets of The 1000 Genomes Project Phase 3 data we show that, relative to WGS, intermediate and long ROA are captured robustly with popular microarray platforms, while detection of short ROA is more variable and improves with marker density. Worldwide ROA patterns inferred from WGS data are found to accord well with those previously reported on the basis of microarray genotype data. Finally, we highlight the potential of this approach to detect genomic regions enriched for autozygosity signals in one group relative to another based upon comparisons of per-individual autozygosity likelihoods instead of inferred ROA frequencies. CONCLUSIONS: This weighted likelihood ROA inference approach can assist population- and disease-geneticists working with a wide variety of data types and species to explore ROA patterns and to identify genomic regions with differential ROA signals among groups, thereby advancing our understanding of evolutionary history and the role of recessive variation in phenotypic variation and disease. PMID- 29191167 TI - Using variant databases for variant prioritization and to detect erroneous genotype-phenotype associations. AB - BACKGROUND: In the search for novel causal mutations, public and/or private variant databases are nearly always used to facilitate the search as they result in a massive reduction of putative variants in one step. Practically, variant filtering is often done by either using all variants from the variant database (called the absence-approach, i.e. it is assumed that disease-causing variants do not reside in variant databases) or by using the subset of variants with an allelic frequency > 1% (called the 1%-approach). We investigate the validity of these two approaches in terms of false negatives (the true disease-causing variant does not pass all filters) and false positives (a harmless mutation passes all filters and is erroneously retained in the list of putative disease causing variants) and compare it with an novel approach which we named the quantile-based approach. This approach applies variable instead of static frequency thresholds and the calculation of these thresholds is based on prior knowledge of disease prevalence, inheritance models, database size and database characteristics. RESULTS: Based on real-life data, we demonstrate that the quantile-based approach outperforms the absence-approach in terms of false negatives. At the same time, this quantile-based approach deals more appropriately with the variable allele frequencies of disease-causing alleles in variant databases relative to the 1%-approach and as such allows a better control of the number of false positives. We also introduce an alternative application for variant database usage and the quantile-based approach. If disease-causing variants in variant databases deviate substantially from theoretical expectancies calculated with the quantile-based approach, their association between genotype and phenotype had to be reconsidered in 12 out of 13 cases. CONCLUSIONS: We developed a novel method and demonstrated that this so-called quantile-based approach is a highly suitable method for variant filtering. In addition, the quantile-based approach can also be used for variant flagging. For user friendliness, lookup tables and easy-to-use R calculators are provided. PMID- 29191165 TI - Renal association clinical practice guideline on Anaemia of Chronic Kidney Disease. AB - Anaemia is a commonly diagnosed complication among patients suffering with chronic kidney disease. If left untreated, it may affect patient quality of life. There are several causes for anaemia in this patient population. As the kidney function deteriorates, together with medications and dietary restrictions, patients may develop iron deficiency, resulting in reduction of iron supply to the bone marrow (which is the body organ responsible for the production of different blood elements). Chronic kidney disease patients may not be able to utilise their own body's iron stores effectively and hence, many patients, particularly those receiving haemodialysis, may require additional iron treatment, usually provided by infusion.With further weakening of kidney function, patients with chronic kidney disease may need additional treatment with a substance called erythropoietin which drives the bone marrow to produce its own blood. This substance, which is naturally produced by the kidneys, becomes relatively deficient in patients with chronic kidney disease. Any patients will eventually require treatment with erythropoietin or similar products that are given by injection.Over the last few years, several iron and erythropoietin products have been licensed for treating anaemia in chronic kidney disease patients. In addition, several publications discussed the benefits of each treatment and possible risks associated with long term treatment. The current guidelines provide advice to health care professionals on how to screen chronic kidney disease patients for anaemia, which patients to investigate for other causes of anaemia, when and how to treat patients with different medications, how to ensure safe prescribing of treatment and how to diagnose and manage complications associated with anaemia and the drugs used for its treatment. PMID- 29191168 TI - Self-reported physical activity correlates in Swedish adults with multiple sclerosis: a cross-sectional study. AB - BACKGROUND: The benefits of physical activity in persons with Multiple Sclerosis (MS) are considerable. Knowledge about factors that correlate to physical activity is helpful in order to develop successful strategies to increase physical activity in persons with MS. Previous studies have focused on correlates to physical activity in MS, however falls self-efficacy, social support and enjoyment of physical activity are not much studied, as well as if the correlates differ with regard to disease severity. The aim of the study was to examine associations between physical activity and age, gender, employment, having children living at home, education, disease type, disease severity, fatigue, self efficacy for physical activity, falls self-efficacy, social support and enjoyment of physical activity in a sample of persons with MS and in subgroups with regard to disease severity. METHODS: This is a cross-sectional survey study including Swedish community living adults with MS, 287 persons, response rate 58.2%. The survey included standardized self-reported scales measuring physical activity, disease severity, fatigue, self-efficacy for physical activity, falls self efficacy, and social support. Physical activity was measured by the Physical Activity Disability Survey - Revised. RESULTS: Multiple regression analyzes showed that 59% (F(6,3) = 64.9, p = 0.000) of the variation in physical activity was explained by having less severe disease (beta = -0.30), being employed (beta = 0.26), having high falls self-efficacy (beta = 0.20), having high self-efficacy for physical activity (beta = 0.17), and enjoying physical activity (beta = 0.11). In persons with moderate/severe MS, self-efficacy for physical activity explained physical activity. CONCLUSIONS: Consistent with previous research in persons with MS in other countries this study shows that disease severity, employment and self-efficacy for physical activity are important for physical activity. Additional important factors were falls self-efficacy and enjoyment. More research is needed to confirm this and the subgroup differences. PMID- 29191166 TI - The insect pathogenic bacterium Xenorhabdus innexi has attenuated virulence in multiple insect model hosts yet encodes a potent mosquitocidal toxin. AB - BACKGROUND: Xenorhabdus innexi is a bacterial symbiont of Steinernema scapterisci nematodes, which is a cricket-specialist parasite and together the nematode and bacteria infect and kill crickets. Curiously, X. innexi expresses a potent extracellular mosquitocidal toxin activity in culture supernatants. We sequenced a draft genome of X. innexi and compared it to the genomes of related pathogens to elucidate the nature of specialization. RESULTS: Using green fluorescent protein-expressing X. innexi we confirm previous reports using culture-dependent techniques that X. innexi colonizes its nematode host at low levels (~3-8 cells per nematode), relative to other Xenorhabdus-Steinernema associations. We found that compared to the well-characterized entomopathogenic nematode symbiont X. nematophila, X. innexi fails to suppress the insect phenoloxidase immune pathway and is attenuated for virulence and reproduction in the Lepidoptera Galleria mellonella and Manduca sexta, as well as the dipteran Drosophila melanogaster. To assess if, compared to other Xenorhabdus spp., X. innexi has a reduced capacity to synthesize virulence determinants, we obtained and analyzed a draft genome sequence. We found no evidence for several hallmarks of Xenorhabdus spp. toxicity, including Tc and Mcf toxins. Similar to other Xenorhabdus genomes, we found numerous loci predicted to encode non-ribosomal peptide/polyketide synthetases. Anti-SMASH predictions of these loci revealed one, related to the fcl locus that encodes fabclavines and zmn locus that encodes zeamines, as a likely candidate to encode the X. innexi mosquitocidal toxin biosynthetic machinery, which we designated Xlt. In support of this hypothesis, two mutants each with an insertion in an Xlt biosynthesis gene cluster lacked the mosquitocidal compound based on HPLC/MS analysis and neither produced toxin to the levels of the wild type parent. CONCLUSIONS: The X. innexi genome will be a valuable resource in identifying loci encoding new metabolites of interest, but also in future comparative studies of nematode-bacterial symbiosis and niche partitioning among bacterial pathogens. PMID- 29191169 TI - Genetic parameters and expected responses to selection for components of feed efficiency in a Duroc pig line. AB - BACKGROUND: Improving feed efficiency ([Formula: see text]) is a key factor for any pig breeding company. Although this can be achieved by selection on an index of multi-trait best linear unbiased prediction of breeding values with optimal economic weights, considering deviations of feed intake from actual needs ([Formula: see text]) should be of value for further research on biological aspects of [Formula: see text]. Here, we present a random regression model that extends the classical definition of [Formula: see text] by including animal specific needs in the model. Using this model, we explore the genetic determinism of several [Formula: see text] components: use of feed for growth ([Formula: see text]), use of feed for backfat deposition ([Formula: see text]), use of feed for maintenance ([Formula: see text]), and unspecific efficiency in the use of feed ([Formula: see text]). Expected response to alternative selection indexes involving different components is also studied. RESULTS: Based on goodness-of-fit to the available feed intake ([Formula: see text]) data, the model that assumes individual (genetic and permanent) variation in the use of feed for maintenance, [Formula: see text] and [Formula: see text] showed the best performance. Joint individual variation in feed allocation to maintenance, growth and backfat deposition comprised 37% of the individual variation of [Formula: see text]. The estimated heritabilities of [Formula: see text] using the model that accounts for animal-specific needs and the traditional [Formula: see text] model were 0.12 and 0.18, respectively. The estimated heritabilities for the regression coefficients were 0.44, 0.39 and 0.55 for [Formula: see text], [Formula: see text] and [Formula: see text], respectively. Estimates of genetic correlations of [Formula: see text] were positive with amount of feed used for [Formula: see text] and [Formula: see text] but negative for [Formula: see text]. Expected response in overall efficiency, reducing [Formula: see text] without altering performance, was 2.5% higher when the model assumed animal-specific needs than when the traditional definition of [Formula: see text] was considered. CONCLUSIONS: Expected response in overall efficiency, by reducing [Formula: see text] without altering performance, is slightly better with a model that assumes animal specific needs instead of batch-specific needs to correct [Formula: see text]. The relatively small difference between the traditional [Formula: see text] model and our model is due to random intercepts (unspecific use of feed) accounting for the majority of variability in [Formula: see text]. Overall, a model that accounts for animal-specific needs for [Formula: see text], [Formula: see text] and [Formula: see text] is statistically superior and allows for the possibility to act differentially on [Formula: see text] components. PMID- 29191170 TI - The Arabidopsis ELP3/ELO3 and ELP4/ELO1 genes enhance disease resistance in Fragaria vesca L. AB - BACKGROUND: Plant immune response is associated with a large-scale transcriptional reprogramming, which is regulated by numerous transcription regulators such as the Elongator complex. Elongator is a multitasking protein complex involved in diverse cellular processes, including histone modification, DNA methylation, and tRNA modification. In recent years, Elongator is emerging as a key regulator of plant immune responses. However, characterization of Elongator's function in plant immunity has been conducted only in the model plant Arabidopsis thaliana. It is thus unclear whether Elongator's role in plant immunity is conserved in higher plants. The objective of this study is to characterize transgenic woodland strawberry (Fragaria vesca L.) overexpressing the Arabidopsis Elongator (AtELP) genes, AtELP3 and AtELP4, and to determine whether F. vesca carries a functional Elongator complex. METHODS: Transgenic F. vesca and Arabidopsis plants were produced via Agrobacterium-mediated genetic transformation and characterized by morphology, PCR, real-time quantitative PCR, and disease resistance test. The Student's t test was used to analyze the data. RESULTS: Overexpression of AtELP3 and AtELP4 in F. vesca impacts plant growth and development and confers enhanced resistance to anthracnose crown rot, powdery mildew, and angular leaf spot, which are caused by the hemibiotrophic fungal pathogen Colletotrichum gloeosporioides, the obligate biotrophic fungal pathogen Podosphaera aphanis, and the hemibiotrophic bacterial pathogen Xanthomonas fragariae, respectively. Moreover, the F. vesca genome encodes all six Elongator subunits by single-copy genes with the exception of FvELP4, which is encoded by two homologous genes, FvELP4-1 and FvELP4-2. We show that FvELP4-1 complemented the Arabidopsis Atelp4/elo1-1 mutant, indicating that FvELP4 is biologically functional. CONCLUSIONS: This is the first report on overexpression of Elongator genes in plants. Our results indicate that the function of Elongator in plant immunity is most likely conserved in F. vesca and suggest that Elongator genes may hold potential for helping mitigate disease severity and reduce the use of fungicides in strawberry industry. PMID- 29191171 TI - Self-assessment of the mental health status in older adults in Poland: a cross sectional study. AB - BACKGROUND: Demographic aging of society poses numerous challenges, including the provision of health care to the elderly population. According to World Health Organization data, the most frequent mental disorders in the senior population are: dementia, depression, and drug and alcohol addiction. The aim of this study was to subjectively assess mental health status (the severity of non-psychotic symptoms of mental functions and depressive symptoms) in older adults of Bialystok (Poland). METHODS: The study included 300 people - inhabitants of Bialystok and its surrounding areas - aged over 60: 100 residents of a nursing home, 100 senior students of the University of the Third Age in Bialystok, and 100 senior students of the University of a Healthy Senior. Two standardized psychometric scales were used in the study: the General Health Questionnaire (GHQ 28) and the Beck Depression Inventory (BDI). RESULTS: The median GHQ total point value equaled 26 points, which indicated possible non-psychotic mental disorders. The overall BDI score showed that respondents had a subjective feeling of depressive symptom intensification at the level of 11 points out of 63 points, which indicated minor depressive disorders. Positive and statistically significant correlations were observed between suspicion of non-psychotic mental disorders and the occurrence of depressive symptoms both without distribution into groups and with distribution into sex, group affiliation, and age. CONCLUSIONS: Subjective assessment of mental health status in older adults, inhabitants of Bialystok, was negative. Social and demographic characteristics (sex, group affiliation, age) analyzed in the study, played no significant role in the assessment of depressive and non-psychotic mental symptom occurrence. Residents of the nursing home were characterized negatively in terms of subjective assessment mental health status from the other two study groups. PMID- 29191172 TI - MicroRNA profile in HBV-induced infection and hepatocellular carcinoma. AB - BACKGROUND: MicroRNAs (miRNAs) exhibit essential regulatory functions related to cell growth, apoptosis, development and differentiation. Dysregulated expression of miRNAs is associated with a wide variety of human diseases. As such miRNA signatures are valuable as biomarkers for disease and for making treatment decisions. Hepatitis B virus (HBV) is a major risk factor for hepatocellular carcinoma (HCC). Here we screened for miRNAs in chronic HBV associated HCC. METHODS: To determine the miRNAs in HCC occurrence associated with HBV infection, we analyzed global miRNA expression profiles in 12 pairs of HCC and adjacent matched non-HCC tissues from HBV-positive and HBV-negative patients using microarray analyses. The microarray result was validated by real-time PCR in 32 HBV-positive and 24 HBV-negative patient HCC samples. The potential candidate target genes of the miRNAs were predicted by miRWalk software. Genes simultaneously predicted as targets by two or more miRNAs were subjected to GO and KEGG pathway analysis. The miRNA regulatory network analysis was performed using the Ingenuity Pathway Analysis (IPA) software. RESULTS: Eight miRNAs (miR 223, miR-98, miR-15b, miR-199a-5p, miR-19b, miR-22, miR-451, and miR-101) were involved in HBV-unrelated HCC, 5 miRNAs (miR-98, miR-375, miR-335, miR-199a-5p, and miR-22) were involved in HBV infection, and 7 miRNAs (miR-150, miR-342-3p, miR-663, miR-20b, miR-92a-3p, miR-376c-3p and miR-92b) were specifically altered in HBV-related HCC. Gene Ontology and KEGG analyses predict that these HBV related HCC miRNAs are involved in the regulation of: transcription, RNA polymerase II promoter, phosphorylation of proteins through MAPK signaling pathway, focal adhesion, and actin cytoskeleton. IPA analysis also suggest that these miRNAs act on AGO2, TP53, CCND1, and 11 other genes that significantly influence HCC occurrence and HBV infection. CONCLUSION: Our data indicates that the unique 7 miRNAs expression signature could be involved in the development HBV related HCC. PMID- 29191173 TI - Identifying levels of general distress in first line mental health services: can GP- and eHealth clients' scores be meaningfully compared? AB - BACKGROUND: The Four-Dimensional Symptom Questionnaire (4DSQ) (Huisarts Wetenschap 39: 538-47, 1996) is a self-report questionnaire developed in the Netherlands to distinguish non-specific general distress from depression, anxiety, and somatization. This questionnaire is often used in different populations and settings and there is a paper-and-pencil and computerized version. METHODS: We used item response theory to investigate whether the 4DSQ measures the same construct (structural equivalence) in the same way (scalar equivalence) in two samples comprised of primary mental health care attendees: (i) clients who visited their General Practitioner responded to the 4DSQ paper and-pencil version, and (ii) eHealth clients responded to the 4DSQ computerized version. Specifically, we investigated whether the distress items functioned differently in eHealth clients compared to General Practitioners' clients and whether these differences lead to substantial differences at scale level. RESULTS: Results showed that in general structural equivalence holds for the distress scale. This means that the distress scale measures the same construct in both General Practitioners' clients and eHealth clients. Furthermore, although eHealth clients have higher observed distress scores than General Practitioners' clients, application of a multiple group generalized partial credit response model suggests that scalar equivalence holds. CONCLUSIONS: The same cutoff scores can be used for classifying respondents as having low, moderate and high levels of distress in both settings. PMID- 29191174 TI - New methods for estimating follow-up rates in cohort studies. AB - BACKGROUND: The follow-up rate, a standard index of the completeness of follow up, is important for assessing the validity of a cohort study. A common method for estimating the follow-up rate, the "Percentage Method", defined as the fraction of all enrollees who developed the event of interest or had complete follow-up, can severely underestimate the degree of follow-up. Alternatively, the median follow-up time does not indicate the completeness of follow-up, and the reverse Kaplan-Meier based method and Clark's Completeness Index (CCI) also have limitations. METHODS: We propose a new definition for the follow-up rate, the Person-Time Follow-up Rate (PTFR), which is the observed person-time divided by total person-time assuming no dropouts. The PTFR cannot be calculated directly since the event times for dropouts are not observed. Therefore, two estimation methods are proposed: a formal person-time method (FPT) in which the expected total follow-up time is calculated using the event rate estimated from the observed data, and a simplified person-time method (SPT) that avoids estimation of the event rate by assigning full follow-up time to all events. Simulations were conducted to measure the accuracy of each method, and each method was applied to a prostate cancer recurrence study dataset. RESULTS: Simulation results showed that the FPT has the highest accuracy overall. In most situations, the computationally simpler SPT and CCI methods are only slightly biased. When applied to a retrospective cohort study of cancer recurrence, the FPT, CCI and SPT showed substantially greater 5-year follow-up than the Percentage Method (92%, 92% and 93% vs 68%). CONCLUSIONS: The Person-time methods correct a systematic error in the standard Percentage Method for calculating follow-up rates. The easy to use SPT and CCI methods can be used in tandem to obtain an accurate and tight interval for PTFR. However, the FPT is recommended when event rates and dropout rates are high. PMID- 29191175 TI - A common base method for analysis of qPCR data and the application of simple blocking in qPCR experiments. AB - BACKGROUND: qPCR has established itself as the technique of choice for the quantification of gene expression. Procedures for conducting qPCR have received significant attention; however, more rigorous approaches to the statistical analysis of qPCR data are needed. RESULTS: Here we develop a mathematical model, termed the Common Base Method, for analysis of qPCR data based on threshold cycle values (C q ) and efficiencies of reactions (E). The Common Base Method keeps all calculations in the logscale as long as possible by working with log10(E) ? C q , which we call the efficiency-weighted C q value; subsequent statistical analyses are then applied in the logscale. We show how efficiency-weighted C q values may be analyzed using a simple paired or unpaired experimental design and develop blocking methods to help reduce unexplained variation. CONCLUSIONS: The Common Base Method has several advantages. It allows for the incorporation of well specific efficiencies and multiple reference genes. The method does not necessitate the pairing of samples that must be performed using traditional analysis methods in order to calculate relative expression ratios. Our method is also simple enough to be implemented in any spreadsheet or statistical software without additional scripts or proprietary components. PMID- 29191176 TI - Mobile electronic versus paper case report forms in clinical trials: a randomized controlled trial. AB - BACKGROUND: Regulations, study design complexity and amounts of collected and shared data in clinical trials render efficient data handling procedures inevitable. Recent research suggests that electronic data capture can be key in this context but evidence is insufficient. This randomized controlled parallel group study tested the hypothesis that time efficiency is superior when electronic (eCRF) instead of paper case report forms (pCRF) are used for data collection. We additionally investigated predictors of time saving effects and data integrity. METHODS: This study was conducted on top of a clinical weight loss trial performed at a clinical research facility over six months. All study nurses and patients participating in the clinical trial were eligible to participate and randomly allocated to enter cross-sectional data obtained during routine visits either through pCRF or eCRF. A balanced randomization list was generated before enrolment commenced. 90 and 30 records were gathered for the time that 27 patients and 2 study nurses required to report 2025 and 2037 field values, respectively. The primary hypothesis, that eCRF use is faster than pCRF use, was tested by a two-tailed t-test. Analysis of variance and covariance were used to evaluate predictors of entry performance. Data integrity was evaluated by descriptive statistics. RESULTS: All randomized patients were included in the study (eCRF group n = 13, pCRF group n = 14). eCRF, as compared to pCRF, data collection was associated with significant time savings across all conditions (8.29 +/- 5.15 min vs. 10.54 +/- 6.98 min, p = .047). This effect was not defined by participant type, i.e. patients or study nurses (F(1,112) = .15, p = .699), CRF length (F(2,112) = .49, p = .609) or patient age (Beta = .09, p = .534). Additional 5.16 +/- 2.83 min per CRF were saved with eCRFs due to data transcription redundancy when patients answered questionnaires directly in eCRFs. Data integrity was superior in the eCRF condition (0 versus 3 data entry errors). CONCLUSIONS: This is the first study to prove in direct comparison that using eCRFs instead of pCRFs increases time efficiency of data collection in clinical trials, irrespective of item quantity or patient age, and improves data quality. TRIAL REGISTRATION: Clinical Trials NCT02649907 . PMID- 29191177 TI - Performance comparison of first-order conditional estimation with interaction and Bayesian estimation methods for estimating the population parameters and its distribution from data sets with a low number of subjects. AB - BACKGROUND: Exploratory preclinical, as well as clinical trials, may involve a small number of patients, making it difficult to calculate and analyze the pharmacokinetic (PK) parameters, especially if the PK parameters show very high inter-individual variability (IIV). In this study, the performance of a classical first-order conditional estimation with interaction (FOCE-I) and expectation maximization (EM)-based Markov chain Monte Carlo Bayesian (BAYES) estimation methods were compared for estimating the population parameters and its distribution from data sets having a low number of subjects. METHODS: In this study, 100 data sets were simulated with eight sampling points for each subject and with six different levels of IIV (5%, 10%, 20%, 30%, 50%, and 80%) in their PK parameter distribution. A stochastic simulation and estimation (SSE) study was performed to simultaneously simulate data sets and estimate the parameters using four different methods: FOCE-I only, BAYES(C) (FOCE-I and BAYES composite method), BAYES(F) (BAYES with all true initial parameters and fixed omega 2 ), and BAYES only. Relative root mean squared error (rRMSE) and relative estimation error (REE) were used to analyze the differences between true and estimated values. A case study was performed with a clinical data of theophylline available in NONMEM distribution media. NONMEM software assisted by Pirana, PsN, and Xpose was used to estimate population PK parameters, and R program was used to analyze and plot the results. RESULTS: The rRMSE and REE values of all parameter (fixed effect and random effect) estimates showed that all four methods performed equally at the lower IIV levels, while the FOCE-I method performed better than other EM-based methods at higher IIV levels (greater than 30%). In general, estimates of random-effect parameters showed significant bias and imprecision, irrespective of the estimation method used and the level of IIV. Similar performance of the estimation methods was observed with theophylline dataset. CONCLUSIONS: The classical FOCE-I method appeared to estimate the PK parameters more reliably than the BAYES method when using a simple model and data containing only a few subjects. EM-based estimation methods can be considered for adapting to the specific needs of a modeling project at later steps of modeling. PMID- 29191178 TI - A fast indirect method to compute functions of genomic relationships concerning genotyped and ungenotyped individuals, for diversity management. AB - BACKGROUND: Pedigree-based management of genetic diversity in populations, e.g., using optimal contributions, involves computation of the [Formula: see text] type yielding elements (relationships) or functions (usually averages) of relationship matrices. For pedigree-based relationships [Formula: see text], a very efficient method exists. When all the individuals of interest are genotyped, genomic management can be addressed using the genomic relationship matrix [Formula: see text]; however, to date, the computational problem of efficiently computing [Formula: see text] has not been well studied. When some individuals of interest are not genotyped, genomic management should consider the relationship matrix [Formula: see text] that combines genotyped and ungenotyped individuals; however, direct computation of [Formula: see text] is computationally very demanding, because construction of a possibly huge matrix is required. Our work presents efficient ways of computing [Formula: see text] and [Formula: see text], with applications on real data from dairy sheep and dairy goat breeding schemes. RESULTS: For genomic relationships, an efficient indirect computation with quadratic instead of cubic cost is [Formula: see text], where Z is a matrix relating animals to genotypes. For the relationship matrix [Formula: see text], we propose an indirect method based on the difference between vectors [Formula: see text], which involves computation of [Formula: see text] and of products such as [Formula: see text] and [Formula: see text], where [Formula: see text] is a working vector derived from [Formula: see text]. The latter computation is the most demanding but can be done using sparse Cholesky decompositions of matrix [Formula: see text], which allows handling very large genomic and pedigree data files. Studies based on simulations reported in the literature show that the trends of average relationships in [Formula: see text] and [Formula: see text] differ as genomic selection proceeds. When selection is based on genomic relationships but management is based on pedigree data, the true genetic diversity is overestimated. However, our tests on real data from sheep and goat obtained before genomic selection started do not show this. CONCLUSIONS: We present efficient methods to compute elements and statistics of the genomic relationships [Formula: see text] and of matrix [Formula: see text] that combines ungenotyped and genotyped individuals. These methods should be useful to monitor and handle genomic diversity. PMID- 29191179 TI - Decontaminating eukaryotic genome assemblies with machine learning. AB - BACKGROUND: High-throughput sequencing has made it theoretically possible to obtain high-quality de novo assembled genome sequences but in practice DNA extracts are often contaminated with sequences from other organisms. Currently, there are few existing methods for rigorously decontaminating eukaryotic assemblies. Those that do exist filter sequences based on nucleotide similarity to contaminants and risk eliminating sequences from the target organism. RESULTS: We introduce a novel application of an established machine learning method, a decision tree, that can rigorously classify sequences. The major strength of the decision tree is that it can take any measured feature as input and does not require a priori identification of significant descriptors. We use the decision tree to classify de novo assembled sequences and compare the method to published protocols. CONCLUSIONS: A decision tree performs better than existing methods when classifying sequences in eukaryotic de novo assemblies. It is efficient, readily implemented, and accurately identifies target and contaminant sequences. Importantly, a decision tree can be used to classify sequences according to measured descriptors and has potentially many uses in distilling biological datasets. PMID- 29191180 TI - White, affluent, educated parents are least likely to choose HPV vaccination for their children: a cross-sectional study of the National Immunization Study - teen. AB - BACKGROUND: Human Papillomavirus (HPV) vaccination coverage is below national goals in the United States. Research is needed to inform strategically designed interventions that target sociodemographic groups with underutilization of HPV vaccination. METHODS: Secondary data analysis of the National Immunization Survey Teen 2013 measured association of sociodemographic factors (e.g., ethnicity/race, insurance) with HPV vaccination among females and males ages 13-17 (N = 18,959). Chi-square and multivariable Poisson regressions were conducted using survey weighted statistics. RESULTS: Having a mother >=35 years, a mother with some college, being of "Other" ethnicity/race, and having no providers who order vaccines from health departments was negatively associated with females initiating HPV vaccination. Having a mother with some college, being of Non Hispanic White or "Other" ethnicity/race, and having some or no providers who order vaccines from health departments was negatively associated with males initiating HPV vaccination. These same factors were negatively associated with males completing HPV vaccination with the exception of "Other" ethnicity/race. In contrast, having an unmarried mother, being ages 15-17, having a hospital based provider, and receiving other adolescent vaccinations were positively associated with females initiating and completing HPV vaccination. Having an unmarried mother, health insurance that is not employer or union sponsored, and influenza and meningitis vaccinations was positively associated with male's initiating HPV vaccination. For males, being 15 or 17 years old and having other adolescent vaccinations was positively associated with vaccine completion. All findings p <= 0.05. CONCLUSIONS: Future HPV vaccination interventions may benefit from targeting certain sociodemographic groups that were negatively associated with HPV vaccination in this study. PMID- 29191181 TI - Immunohistochemistry defined subtypes of breast cancer in 678 Sudanese and Eritrean women; hospitals based case series. AB - BACKGROUND: Breast cancer is the most common malignancy accounting for 25% of all cancers in females. In Africa, breast cancer prevalence and mortality are steadily increasing. Knowledge of hormone receptors and human epidermal growth factor receptor-2 (HER-2) expressions are vital for breast cancer management plans and decision making. There is wide regional variation in the proportion of these biomarkers, especially in African countries. Hormone receptors positivity in indigenous African and African American women is considered to be low and triple negative breast cancer is a dominant phenotype. There is paucity of data regarding hormone receptors (ER and PR) and HER2 expressions in North-eastern Africa (Eritrea and Sudan). The purpose of this study was to evaluate the expression of ER, PR and HER2 in Eritrean and Sudanese case series and correlate these biomarkers with the clinicopathological profile. METHOD: Clinicopathologic data of patients were collected from clinical records. Immunohistochemistry biomarkers (ER, PR, and HER2) were assessed in consecutive female patients who had been diagnosed with invasive breast cancer from 2011 to 2015 in Gezira University Pathology Laboratory, the Sudan and National Health laboratory, Asmara, Eritrea. RESULTS: There were 678 cases involved in this study. The mean age was 48.8 years with +/-0.53 standard error of the mean. Two-thirds of the case were <=50 years. Invasive ductal carcinoma, no special type was the most dominant histologic type (86%) in both study groups. The majority of cases (70%) had tumour stage pT2 and pT3 and about 50% had lymph node involvement. Less than 5% of the cases had well-differentiated tumours. The ER, PR and HER2 positive rates were 45%, 32%, and 29%, respectively. The proportion of luminal-A like, luminal-B like, HER2 enriched and TNBC were 37%, 13%, 16% and 34%, respectively. Fisher extract analysis showed age (p = .015), tumour size (p = .041), and histologic grade (p = .000) were significantly associated with intrinsic subtypes. Furthermore, Logistic regression analysis stratified by origin, age, tumour size, lymph-node metastasis and grade indicated that younger women age (<=50 years) and grade III tumours were more likely to be diagnosed with ER negative breast cancer. CONCLUSION: Most of Sudanese and Eritrean women were diagnosed at younger age and with unfavourable prognostic clinicopathologic prognostic markers. TNBC is more frequent in this cohort study; patients with grade III tumours and young age are more likely to be hormone receptors negative. Therefore, routine determination of hormone receptors is warranted for appropriate targeted therapy. PMID- 29191182 TI - What systemic factors contribute to collaboration between primary care and public health sectors? An interpretive descriptive study. AB - BACKGROUND: Purposefully building stronger collaborations between primary care (PC) and public health (PH) is one approach to strengthening primary health care. The purpose of this paper is to report: 1) what systemic factors influence collaborations between PC and PH; and 2) how systemic factors interact and could influence collaboration. METHODS: This interpretive descriptive study used purposive and snowball sampling to recruit and conduct interviews with PC and PH key informants in British Columbia (n = 20), Ontario (n = 19), and Nova Scotia (n = 21), Canada. Other participants (n = 14) were knowledgeable about collaborations and were located in various Canadian provinces or working at a national level. Data were organized into codes and thematic analysis was completed using NVivo. The frequency of "sources" (individual transcripts), "references" (quotes), and matrix queries were used to identify potential relationships between factors. RESULTS: We conducted a total of 70 in-depth interviews with 74 participants working in either PC (n = 33) or PH (n = 32), both PC and PH (n = 7), or neither sector (n = 2). Participant roles included direct service providers (n = 17), senior program managers (n = 14), executive officers (n = 11), and middle managers (n = 10). Seven systemic factors for collaboration were identified: 1) health service structures that promote collaboration; 2) funding models and financial incentives supporting collaboration; 3) governmental and regulatory policies and mandates for collaboration; 4) power relations; 5) harmonized information and communication infrastructure; 6) targeted professional education; and 7) formal systems leaders as collaborative champions. CONCLUSIONS: Most themes were discussed with equal frequency between PC and PH. An assessment of the system level context (i.e., provincial and regional organization and funding of PC and PH, history of government in successful implementation of health care reform, etc) along with these seven system level factors could assist other jurisdictions in moving towards increased PC and PH collaboration. There was some variation in the importance of the themes across provinces. British Columbia participants more frequently discussed system structures that could promote collaboration, power relations, harmonized information and communication structures, formal systems leaders as collaboration champions and targeted professional education. Ontario participants most frequently discussed governmental and regulatory policies and mandates for collaboration. PMID- 29191183 TI - An economic model of advance care planning in Australia: a cost-effective way to respect patient choice. AB - BACKGROUND: Advance care planning (ACP) is a process of planning for future health and personal care. A person's values and preferences are made known so that they can guide decision making at a future time when that person cannot make or communicate his or her decisions. This is particularly relevant for people with dementia because their ability to make decisions progressively deteriorates over time. This study aims to evaluate the cost-effectiveness of delivering a nationwide ACP program within the Australian primary care setting. METHODS: A decision analytic model was developed to identify the costs and outcomes of an ACP program for people aged 65+ years who were at risk of developing dementia. Inputs for the model was sourced and estimated from the literature. The reliability of the results was thoroughly tested in sensitivity analyses. RESULTS: The results showed that, compared to usual care, a nationwide ACP program for people aged 65+ years who were at risk of dementia would be cost effective. However, the results only hold if ACP completion is higher than 50% and adherence to ACP wishes is above 75%. CONCLUSIONS: A nationwide ACP program in the primary care setting is a cost-effective or cost-saving intervention compared to usual care in a population at-risk of developing dementia. Cost savings are generated from providing treatment and care that is consistent with patient preferences, resulting in fewer hospitalisations and less-intensive care at end-of-life. PMID- 29191184 TI - Accessibility of general and specialized obstetric care providers in Germany and England: an analysis of location and neonatal outcome. AB - BACKGROUND: Health care accessibility is known to differ geographically. With this study we focused on analysing accessibility of general and specialized obstetric units in England and Germany with regard to urbanity, area deprivation and neonatal outcome using routine data. METHODS: We used a floating catchment area method to measure obstetric care accessibility, the degree of urbanization (DEGURBA) to measure urbanity and the index of multiple deprivation to measure area deprivation. RESULTS: Accessibility of general obstetric units was significantly higher in Germany compared to England (accessibility index of 16.2 vs. 11.6; p < 0.001), whereas accessibility of specialized obstetric units was higher in England (accessibility index for highest level of care of 0.235 vs. 0.002; p < 0.001). We further demonstrated higher obstetric accessibility for people living in less deprived areas in Germany (r = - 0.31; p < 0.001) whereas no correlation was present in England. There were also urban-rural disparities present, with higher accessibility in urban areas in both countries (r = 0.37 0.39; p < 0.001). The analysis did not show that accessibility affected neonatal outcomes. Finally, our computer generated model for obstetric care provider demand in terms of birth counts showed a very strong correlation with actual birth counts at obstetric units (r = 0.91-0.95; p < 0.001). CONCLUSION: In Germany the focus of obstetric care seemed to be put on general obstetric units leading to higher accessibility compared to England. Regarding specialized obstetric care the focus in Germany was put on high level units whereas in England obstetric care seems to be more balanced between the different levels of care with larger units on average leading to higher accessibility. PMID- 29191186 TI - Roles and responsibilities of clinical ethics committees in priority setting. AB - BACKGROUND: Fair prioritization of healthcare resources has been on the agenda for decades, but resource allocation dilemmas in clinical practice remain challenging. Can clinical ethics committees (CECs) be of help? The aim of the study was to explore whether and how CECs handle priority setting dilemmas and contribute to raising awareness of fairness concerns. METHOD: Descriptions of activities involving priority setting in annual reports from Norwegian CECs (2003 2015) were studied and categorized through qualitative content analysis. RESULTS: Three hundred thirty-nine reports from 38 CECs were studied. We found 78 activities where resource use or priority setting were explicitly highlighted as main topics. Of these, 29 were seminars or other educational activities, 21 were deliberations on individual patient cases, whereas 28 were discussions of principled or general cases. Individual patient cases concerned various distributional dilemmas where values were at stake. Six main topics and seven roles for the CEC were identified. CECs handle issues concerning the introduction of new costly drugs, extraordinarily costly established treatment, the application of priority setting criteria, resource use for vulnerable groups, resource constraints compromising practice, and futility of care. The CEC can act as an analyst, advisor, moderator, disseminator, facilitator, watch dog, and guardian of values and laws. DISCUSSION: In order to fulfil their responsibilities in handling priority setting cases, CECs need knowledge of both the ethics and the institutionalized systems of priority setting. There is potential for developing this aspect of the CECs' work further. CONCLUSIONS: The Norwegian CECs are involved in priority setting decisions where they can play multiple constructive roles. In particular, they advise and raise awareness of ethical aspects in resource allocations; bridge clinical practice with higher level decisions; and promote fair resource allocation and stakeholder rights and interests. PMID- 29191185 TI - Compassionate collaborative care: an integrative review of quality indicators in end-of-life care. AB - BACKGROUND: Compassion and collaborative practice are individually associated with high quality healthcare. When combined in a compassionate collaborative care (CCC) practice framework, they are reported to improve health, strengthen care provision, and control health costs. Little is known about how to integrate and measure CCC, yet it is fundamentally applied in palliative and end-of-life care settings. This study aimed to identify quality indicators of CCC by systematically reviewing and synthesizing the current state of the palliative and end-of-life care literature. METHODS: An integrative review of the palliative and end-of-life care literature was conducted using Whittemore and Knafl's method. Donabedian's healthcare quality framework was applied in the data analysis phase to organize and display the data. The analysis involved an iterative process that applied a constant comparative method. RESULTS: The final literature sample included 25 articles. Patient and family-centered care emerged as a primary structure for CCC, with overarching values including empathy, sharing, respect, and partnership. The analysis revealed communication, shared decision-making, and goal setting as overarching processes for achieving CCC at end-of-life. Patient and family satisfaction, enhanced teamwork, decreased staff burnout, and organizational satisfaction are exemplars of outcomes that suggest high quality CCC. Specific quality indicators at the individual, team and organizational levels are reported with supporting exemplar data. CONCLUSIONS: CCC is inextricably linked to the inherent values, needs and expectations of patients, families and healthcare providers. Compassion and collaboration must be enacted and harmonized to fully operationalize and sustain patient and family-centered care in palliative and end-of-life practice settings. Towards that direction, the quality indicators that emerged from this integrative review provide a two-fold application in palliative and end-of-life care. First, to evaluate the existing structures, processes, and outcomes at the patient-family, provider, team, and organizational levels. Second, to guide the planning and implementation of team and organizational changes that improve the quality delivery of CCC. PMID- 29191187 TI - Clinical value of a prophylactic minitracheostomy after esophagectomy: analysis in patients at high risk for postoperative pulmonary complications. AB - BACKGROUND: The aim of this study is to evaluate the clinical value of a prophylactic minitracheostomy (PMT) in patients undergoing an esophagectomy for esophageal cancer and to clarify the indications for a PMT. METHODS: Ninety-four patients who underwent right transthoracic esophagectomy for esophageal cancer between January 2009 and December 2013 were studied. Short surgical outcomes were retrospectively compared between 30 patients at high risk for postoperative pulmonary complications who underwent a PMT (PMT group) and 64 patients at standard risk without a PMT (non-PMT group). Furthermore, 12 patients who required a delayed minitracheostomy (DMT) due to postoperative sputum retention were reviewed in detail, and risk factors related to a DMT were also analyzed to assess the indications for a PMT. RESULTS: Preoperative pulmonary function was lower in the PMT group than in the non-PMT group: FEV1.0 (2.41 vs. 2.68 L, p = 0.035), and the proportion of patients with FEV1.0% <60 (13.3% vs. 0%, p = 0.009). No between-group differences were observed in the proportion of patients who suffered from postoperative pneumonia, atelectasis, or re-intubation due to respiratory failure. Of the 12 patients with a DMT, 11 developed postoperative pneumonia, and three required re-intubation due to severe pneumonia. Multivariate analysis revealed FEV1.0% <70% and vocal cord palsy were independent risk factors related to a DMT. CONCLUSION: A PMT for high-risk patients may prevent an increase in the incidence of postoperative pneumonia and re-intubation. The PMT indications should be expanded for patients with vocal cord palsy or mild obstructive respiratory disturbances. PMID- 29191188 TI - Construct validation and correlates of preoperative expectations of postsurgical recovery in persons undergoing knee replacement: baseline findings from a randomized clinical trial. AB - BACKGROUND: A patient's recovery expectations prior to knee arthroplasty influence postsurgical outcome and satisfaction but a unidimensional measure of expectation has not been reported in the literature. Our primary purpose was to determine the extent to which a patient expectations scale reflects a unidimensional construct. Our second purpose was to identify pre-operative variables associated with patients' expectations. We hypothesized that previously identified predictors of the latent expectation scale score would be associated with expectations and that previously unexplored variables of pain catastrophizing, depressive and anxiety symptoms, self-efficacy and number of painful body regions would also associate with pre-operative expectations. METHODS: Our randomized clinical trial had 384 patients assessed prior to knee replacement surgery. The expectations scale along with several predictor variables including WOMAC, psychological distress, and sociodemographic variables were obtained. Confirmatory factor analysis tested the unidimensionality of the measure and structural equation modeling identified predictors of the latent expectations measure. RESULTS: The expectations scale was found to be unidimensional with superior model fit (chi2 = 1.481; df = 2; p = 0.224; RMSEA = 0.035; 90% CI = [0-0.146]; CFI = 0.999; TLI = 0.993). The only variable significantly associated with expectations in the multivariate model was self efficacy. CONCLUSIONS: The expectations scale used in our study demonstrated unidimensionality and has strong potential for clinical application. Poor self efficacy is a potential target for intervention given its independent association with expectation. Addressing expectations directly and indirectly through self efficacy assessment may assist in better aligning patient's expectations with likely outcome. TRIAL REGISTRATION: ClinicalTrials.gov NCT01620983 . PMID- 29191189 TI - Fostering clinical reasoning in physiotherapy: comparing the effects of concept map study and concept map completion after example study in novice and advanced learners. AB - BACKGROUND: Health profession learners can foster clinical reasoning by studying worked examples presenting fully worked out solutions to a clinical problem. It is possible to improve the learning effect of these worked examples by combining them with other learning activities based on concept maps. This study investigated which combinaison of activities, worked examples study with concept map completion or worked examples study with concept map study, fosters more meaningful learning of intervention knowledge in physiotherapy students. Moreover, this study compared the learning effects of these learning activity combinations between novice and advanced learners. METHODS: Sixty-one second-year physiotherapy students participated in the study which included a pre-test phase, a 130-min guided-learning phase and a four-week self-study phase. During the guided and self-study learning sessions, participants had to study three written worked examples presenting the clinical reasoning for selecting electrotherapeutic currents to treat patients with motor deficits. After each example, participants engaged in either concept map completion or concept map study depending on which learning condition they were randomly allocated to. Students participated in an immediate post-test at the end of the guided-learning phase and a delayed post-test at the end of the self-study phase. Post-tests assessed the understanding of principles governing the domain of knowledge to be learned (conceptual knowledge) and the ability to solve new problems that have similar (i.e., near transfer) or different (i.e., far transfer) solution rationales as problems previously studied in the examples. RESULTS: Learners engaged in concept map completion outperformed those engaged in concept map study on near transfer (p = .010) and far transfer (p < .001) performance. There was a significant interaction effect of learners' prior ability and learning condition on conceptual knowledge but not on near and far transfer performance. CONCLUSIONS: Worked examples study combined with concept map completion led to greater transfer performance than worked examples study combined with concept map study for both novice and advanced learners. Concept map completion might give learners better insight into what they have and have not yet learned, allowing them to focus on those aspects during subsequent example study. PMID- 29191190 TI - The effects of freeze-dried Ganoderma lucidum mycelia on a recurrent oral ulceration rat model. AB - BACKGROUND: Conventional scientific studies had supported the use of polysaccharides and beta-glucans from a number of fungi, including Ganoderma lucidum for the treatment of recurrent oral ulceration (ROU). Our aim of the present study was to evaluate whether freeze-dried powder from G. lucidum mycelia (FDPGLM) prevents ROU in rats. METHODS: A Sprague-Dawley (SD) rat model with ROU was established by autoantigen injection. The ROU rats were treated with three different dosages of FDPGLM and prednisone acetate (PA), and their effects were evaluated according to the clinical therapeutic evaluation indices of ROU. RESULTS: High-dose FDPGLM induced significantly prolonged total intervals and a reduction in the number of ulcers and ulcer areas, thereby indicating that the treatment was effective in preventing ROU. Enzyme-linked immunosorbent assay (ELISA) showed that high-dose FDPGLM significantly enhanced the serum transforming growth factor-beta1 (TGF-beta1) levels, whereas reduced those of interleukin-6 (IL-6) and interleukin-17 (IL-17). Flow cytometry (FCM) showed that the proportion of CD4+ CD25+ Foxp3+ (forkhead box P3) regulatory T cells (Tregs) significantly increased by 1.5-fold in the high-dose FDPGLM group compared to that in the rat model group (P < 0.01). The application of middle- and high-dose FDPGLM also resulted in the upregulation of Foxp3 and downregulation of retinoid related orphan receptor gamma t(RORgammat) mRNA. CONCLUSION: High-dose FDPGLM possibly plays a role in ROU by promoting CD4+ CD25+ Foxp3+ Treg and inhibiting T helper cell 17 differentiation. This study also shows that FDPGLM may be potentially used as a complementary and alternative medicine treatment scheme for ROU. PMID- 29191192 TI - Anticancer activities of ethanol extract from the Antarctic freshwater microalga, Botryidiopsidaceae sp. AB - BACKGROUND: Cancer is a leading cause of human death around the world and occurs through the highly complex coordination of multiple cellular pathways. Recent studies have revealed that microalgal extracts exhibit considerable pharmaceutical activities, including those against various cancer cells. Thus, microalgae are promising candidates as novel cancer therapeutic drugs. In this study, we evaluated the biological functions of the ethanolic extract of the Antarctic freshwater microalga, Bo tryidiopsidaceae sp., such as its antioxidant, anti-proliferative, apoptotic and anti-invasive properties. METHODS: To estimate antioxidant capacity of ethanol extract of Bo tryidiopsidaceae sp. (ETBO), free radical 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) and 1,1 diphenyl-2-picrylhydrazyl (DPPH) assays were used. The anti-proliferative activity of ETBO was assessed in several cancer cell lines (A375, Hs578T and HeLa) and non-tumorigenic keratinocyte cells (HaCaT), using MTT assay. In addition, Annexin V binding was performed to detect ETBO-induced apoptotic cells, and the expression levels of apoptosis-regulating proteins, caspase-3, p53, and Bcl-2, were determined by western blot. Boyden chamber assays were used to determine anti-migratory and anti-invasive properties of ETBO. RESULTS: ETBO exhibited antioxidant activity and concentration-dependent anticancer activities, such as anti-proliferation and pro-apoptotic activities against cancer cells. Furthermore, the expression of the apoptosis-inducing proteins, p53 and caspase 3, significantly increased in response to ETBO, whereas the expression of the anti-apoptotic protein, Bcl-2, decreased. These data imply that ETBO induces apoptosis by caspase activation through the modulation of pro-apoptotic and anti apoptotic gene, p53 and Bcl-2, respectively. In addition, ETBO significantly inhibited migration and invasion of cervical cancer cells in a concentration dependent manner. CONCLUSION: In this study, ETBO exhibited considerable anticancer activities, such as inhibition of proliferation, invasion, and migration, as well as induction of apoptosis. These data suggest that ETBO is a promising therapeutic agent in cancer therapy and drug discovery. PMID- 29191191 TI - Asymptomatic infections with highly polymorphic Chlamydia suis are ubiquitous in pigs. AB - BACKGROUND: Chlamydia suis is an important, globally distributed, highly prevalent and diverse obligate intracellular pathogen infecting pigs. To investigate the prevalence and genetic diversity of C. suis in China, 2,137 nasal, conjunctival, and rectal swabs as well as whole blood and lung samples of pigs were collected in 19 regions from ten provinces of China in this study. RESULTS: We report an overall positivity of 62.4% (1,334/2,137) of C. suis following screening by Chlamydia spp. 23S rRNA-based FRET-PCR and high-resolution melting curve analysis and confirmatory sequencing. For C. suis-positive samples, 33.3 % of whole blood and 62.5% of rectal swabs were found to be positive for the C. suis tetR(C) gene, while 13.3% of whole blood and 87.0% of rectal swabs were positive for the C. suis tet(C) gene. Phylogenetic comparison of partial C. suis ompA gene sequences revealed significant genetic diversity in the C. suis strains. This genetic diversity was confirmed by C. suis-specific multilocus sequence typing (MLST), which identified 26 novel sequence types among 27 examined strains. Tanglegrams based on MLST and ompA sequences provided evidence of C. suis recombination amongst the strains analyzed. CONCLUSIONS: Genetically highly diverse C. suis strains are exceedingly prevalent in pigs. As it stands, the potential pathogenic effect of C. suis on pig health and production of C. suis remains unclear and will be the subject of further investigations. Further study is also required to address the transmission of C. suis between pigs and the risk of 'spill-over' and 'spill-back' of infections to wild animals and humans. PMID- 29191194 TI - Integrating herbal medicine into mainstream healthcare in Ghana: clients' acceptability, perceptions and disclosure of use. AB - BACKGROUND: Although there are current efforts to integrate herbal medicine (HM) into mainstream healthcare in Ghana, there is paucity of empirical evidence on the acceptability and concurrent use of HM, in the formal health facilities in Ghana. This study sought to determine client perception, disclosure and acceptability of integrating herbal medicine in mainstream healthcare in Kumasi, Ghana. METHODS: A cross-sectional study was conducted from May to August, 2015. Five hundred patients presenting at the outpatient departments of Kumasi South, Suntreso and Tafo Government Hospitals in Kumasi were randomly selected. Interviews were conducted with the use of structured questionnaires. A logistic regression analysis, using backward selection, was conducted to determine the influence of socio-demographic and facility related factors on the odds of using HM at the facility. All statistical tests were two-sided and considered significant at a p-value of <0.05. RESULTS: Majority of the study respondents were females (64.8%) and the median age was 36 years. Less than half, 42.2%, of the respondents utilized HM services when they visited the health facility. Reasons for using HM at the facility level included 'being effective' (24.4%), 'easy to access' (25.3%) and 'being comparatively cheaper' (16%). About 86% never disclosed previous use of HM to their health care providers. Socio-economic status and perception of service provision influenced use of herbal medicines. Respondents who rated themselves wealthy had increased odds of using herbal medicines at the health facility as compared to those who rated themselves poor (OR = 4.9; 95%CI = 1.6-15.3). CONCLUSION: This study shows that integration of herbal medicine is feasible and herbal medicines may be generally accepted as a formal source of healthcare in Ghana. The results of this study might serve as a basis for improvement and upscale of the herbal medicine integration programme in Ghana. PMID- 29191193 TI - Adequacy of control of cardiovascular risk factors in ambulatory patients with type 2 diabetes attending diabetes out-patients clinic at a county hospital, Kenya. AB - BACKGROUND: Type 2 diabetes is associated with substantial cardiovascular morbidity and mortality arising from the high prevalence of cardiovascular risk factors such as hypertension, dyslipidaemia, obesity, poor glycaemic control and albuminuria. Adequacy of control of these risk factors determines the frequency and outcome of cardiovascular events in the patients. Current clinical practice guidelines emphasize primary prevention of cardiovascular disease in type 2 diabetes. There is scarce data from the developing countries, Kenya included, on clinical care of patients with type 2 diabetes in the regions that are far away from tertiary health facilities. So we determined the adequacy of control of the modifiable risk factors: glycaemic control, hypertension, dyslipidemia, obesity and albuminuria in the study patients from rural and peri-urban dwelling. METHODS: This was a cross-sectional study on 385 randomly selected ambulatory patients with type 2 diabetes without overt complications. They were on follow up for at least 6 months at the Out-patient diabetes clinic of Nyeri County Hospital, a public health facility located in the central region of Kenya. RESULTS: Females were 65.5%. The study subjects had a mean duration of diabetes of 9.4 years, IQR of 3.0-14 years. Their mean age was 63.3 years, IQR of 56-71 years. Only 20.3% of our subjects had simultaneous optimal control of the three (3) main cardiovascular risk factors of hypertension, high LDL-C and hyperglycaemia at the time of the study. The prevalence of cardiovascular risk factors were as follows: HbA1c above 7% was 60.5% (95% CI, 55.6-65.5), hypertension, 49.6% of whom 76.6% (95% CI, 72.5-80.8) were poorly controlled. High LDL-Cholesterol above 2.0 mmol/L was found in 77.1% (95% CI 73.0-81.3) and Albuminuria occurred in 32.7% (95% CI 27.8-37.4). The prevalence of the other habits with cardiovascular disease risk were: excess alcohol intake at 26.5% (95% CI 27.8-37.4) and cigarette-smoking at 23.6%. A modest 23.4% of the treated patients with hypertension attained target blood pressure of <140/90 mmHg. Out of a paltry 12.5% of the statin-treated patients and others not actively treated, only 22.9% had LDL-Cholesterol of target <2.0 mmol/L. There were no obvious socio demographic and clinical determinants of poor glycaemic control. However, old age above 50 yrs., longer duration with diabetes above 5 yrs. and advanced stages of CKD were significantly associated with hypertension. Female gender and age, statin non-use and socio-economic factor of employment were the significant determinants of high levels of serum LDL-cholesterol. CONCLUSION: The majority of the study patients attending this government-funded health facility had high prevalence of cardiovascular risk factors that were inadequately controlled. Therefore patients with type 2 diabetes should be risk-stratified by their age, duration of diabetes and cardiovascular risk factor loading. Consequently, composite risk factor reduction strategies are needed in management of these patients to achieve the desired targets safely. This would be achieved through innovative care systems and modes of delivery which would translate into maximum benefit of primary cardiovascular disease prevention in those at high risk. It is a desirable quality objective to have a higher proportion of the patients who access care benefiting maximally more than the numbers we are achieving now.

PMID- 29191195 TI - Maternal dietary free or bound fructose diversely influence developmental programming of lipogenesis. AB - BACKGROUND: Maternal dietary choices throughout preconception, pregnancy, and lactation irreversibly affect the development of fetal tissues and organs, known as fetal programming. Recommendations tend to emphasize reducing added sugars. However, the impact of maternal dietary free or bound fructose in added sugars on developmental programming of lipogenesis is unknown. METHODS: Virgin Sprague Dawley rats were randomly divided into five groups. Rats were given feed and plain water (control) or water containing maltodextrin (vehicle), fructose, high fructose corn syrup (HFCS) containing 55% fructose, sucrose (20% w/v) for 12 weeks before mating and throughout the pregnancy and lactation periods. Body weight, water, and feed intake were measured throughout the study. At the end of the lactation period, blood was drawn to determine the fasting levels of glucose, insulin, triglycerides, and non-esterified fatty acids (NEFA) in blood. Triglycerides and acetyl Co-A Carboxylase-1 (ACC1) levels in livers were analyzed, and insulin resistance was calculated. RESULTS: The energy intake of dams in the HFCS group was higher than in the fructose group, while weight gain was less in the HFCS group than in the fructose group. HFCS resulted in greater insulin resistance in dams, whereas free fructose had a robust effect on the fetal programming of insulin resistance. Free fructose and HFCS in the maternal diet increased blood and liver triglycerides and NEFA content in pups. Furthermore, fructose and HFCS exposure increased phosphorylated ACC1 as compared to maltodextrin and control, indicating greater fatty acid synthesis in pups and dams. CONCLUSION: Different types of added sugar in the maternal diet have different metabolic effects on the developmental programming of lipogenesis. Consequently, high fructose intake via processed foods may increase the risk for chronic diseases, and free fructose might contribute to developmental programming of chronic diseases more than bound fructose. PMID- 29191197 TI - In vitro and in vivo aphrodisiac properties of the seed extract from Allium tuberosum on corpus cavernosum smooth muscle relaxation and sexual behavior parameters in male Wistar rats. AB - BACKGROUND: Allium tuberosum is a well-known spice as well as a herb in traditional Chinese medicine, used for increasing libido and treating erectile dysfunction. However, not many studies have been done to evaluate the sexual enhancing properties of A. tuberosum. The aim of this study was to evaluate the aphrodisiac and vasorelaxant properties of A. tuberosum on corpus cavernosum smooth muscle (CCSM) as well as checking the effect on enhancing male rat sexual behavior, libido, potency as well as its spermatogenic properties. METHOD: The seeds were powdered and sequentially extracted with hexane, ethyl acetate and butanol. Male Wistar rats were administered with graded doses of the n-BuOH extracts (ATB) of A. tuberosum (50, 100, 200 and 400 mg/kg) and Viagra was used as the positive control drug. The extract/drug was administered by gastric probe once daily for 45 days and the sexual behavior was analyzed by exposing the male rats to female rats in the estrus period. RESULTS: ATB relaxed corpus cavernosum smooth muscle (68.9%) at a concentration of 200 MUg/ml. The results obtained from the animal studies indicated that ATB significantly increased mount frequency (MF), intromission frequency (IF), ejaculation frequency (EF), ejaculation latency (EL) and markedly reduced post ejaculatory interval (PEI), mount latency (ML), and intromission latency (IL). Furthermore, a remarkable increase in the test for potency was observed as witnessed by marked increase in erections, quick flips, long flips and total reflex. In addition, ATB significantly improved the sperm viability and count as well as increased the concentrations of testosterone, follicle stimulating hormone (FSH), and phosphatases in the treated animals. CONCLUSION: Thus our results suggest that A. tuberosum could stimulate sexual arousal and enhance sexual execution in male rats, thus providing valuable experimental evidence that A. tuberosum possesses sexual enhancing properties. PMID- 29191198 TI - Relationship between screw sagittal angle and stress on endplate of adjacent segments after anterior cervical corpectomy and fusion with internal fixation: a Chinese finite element study. AB - BACKGROUND: In order to reduce the incidence of adjacent segment disease (ASD), the current study was designed to establish Chinese finite element models of normal 3rd~7th cervical vertebrae (C3-C7) and anterior cervical corpectomy and fusion (ACCF) with internal fixation , and analyze the influence of screw sagittal angle (SSA) on stress on endplate of adjacent cervical segments. METHODS: Mimics 8.1 and Abaqus/CAE 6.10 softwares were adopted to establish finite element models. RESULTS: For C4 superior endplate and C6 inferior endplate, their anterior areas had the maximum stress in anteflexion position, and their posterior areas had the maximum stress in posterior extension position. As SSA increased, the stress reduced. With an increase of 10 degrees in SSA, the stress on anterior areas of C4 superior endplate and C6 inferior endplate reduced by 12.67% and 7.99% in anteflexion position, respectively. With an increase of 10 degrees in SSA, the stress on posterior areas of C4 superior endplate and C6 inferior endplate reduced by 9.68% and 10.22% in posterior extension position, respectively. CONCLUSIONS: The current study established Chinese finite element models of normal C3-C7 and ACCF with internal fixation , and demonstrated that as SSA increased, the stress on endplate of adjacent cervical segments decreased. In clinical surgery, increased SSA is able to play important role in protecting the adjacent cervical segments and reducing the incidence of ASD. PMID- 29191199 TI - Paraffin immunofluorescence for detection of immune complexes in renal biopsies: an efficient salvage technique for diagnosis of glomerulonephritis in dogs. AB - BACKGROUND: Renal biopsy is an essential tool for the diagnosis of proteinuric kidney diseases in dogs, and evaluation of immune complexes (IC) by immunofluorescence (IF) of frozen sections (IF-F) is required for the diagnosis of IC-mediated glomerulonephritis (ICGN). However, the use of frozen sections from renal biopsies can have limitations. The aim of this study was to develop a reliable IF method using formalin-fixed and paraffin-embedded (FFPE) sections to detect ICs in dog ICGN. METHODS: Renal biopsy specimens were obtained from dogs with protein-losing nephropathies. FFPE sections were prepared, and eight antigen retrieval pretreatment protocols were performed: digestion with trypsin, microwave (MW) heating in citrate buffer (MW-CB; pH 6.0), MW heating in Tris-EDTA buffer (MW-TEB; pH 9.0), as well as combinations of the above, and a non-treated control. RESULTS: A combination of trypsin for 30 min (Try-30) and MW-TEB; pH 9.0 was the most effective antigen retrieval pretreatment, with clear positive signals for IgG, IgA, IgM, and C3 detected by IF-FFPE. Granular signals, an important diagnostic indicator of ICGN, were clearly observed by both IF-F and IF FFPE after combined pretreatment with Try-30 and MW-TEB, and IgG, IgA, IgM, and C3 signals were almost completely matched in all samples by IF-F and IF-FFPE. CONCLUSION: IF-FFPE with Try-30 and MW-TEB pretreatment is a valuable technique for the diagnosis of renal diseases in dogs. This method could be an efficient tool when standard IF-F cannot be used, or does not provide useful results due to lack of glomeruli in the specimens for IF-F. PMID- 29191200 TI - Emergency general surgery in Rwandan district hospitals: a cross-sectional study of spectrum, management, and patient outcomes. AB - BACKGROUND: Management of emergency general surgical conditions remains a challenge in rural sub-Saharan Africa due to issues such as insufficient human capacity and infrastructure. This study describes the burden of emergency general surgical conditions and the ability to provide care for these conditions at three rural district hospitals in Rwanda. METHODS: This retrospective cross-sectional study included all patients presenting to Butaro, Kirehe and Rwinkwavu District Hospitals between January 1st 2015 and December 31st 2015 with emergency general surgical conditions, defined as non-traumatic, non-obstetric acute care surgical conditions. We describe patient demographics, clinical characteristics, management and outcomes. RESULTS: In 2015, 356 patients presented with emergency general surgical conditions. The majority were male (57.2%) and adults aged 15-60 years (54.5%). The most common diagnostic group was soft tissue infections (71.6%), followed by acute abdominal conditions (14.3%). The median length of symptoms prior to diagnosis differed significantly by diagnosis type (p < 0.001), with the shortest being urological emergencies at 1.5 days (interquartile range (IQR):1, 6) and the longest being complicated hernia at 17.5 days (IQR: 1, 208). Of all patients, 54% were operated on at the district hospital, either by a general surgeon or general practitioner. Patients were more likely to receive surgery if they presented to a hospital with a general surgeon compared to a hospital with only general practitioners (75% vs 43%, p < 0.001). In addition, the general surgeon was more likely to treat patients with complex diagnoses such as acute abdominal conditions (33.3% vs 4.1%, p < 0.001) compared to general practitioners. For patients who received surgery, 73.3% had no postoperative complications and 3.2% died. CONCLUSION: While acute abdominal conditions are often considered the most common emergency general surgical condition in sub Saharan Africa, soft tissue infections were the most common in our setting. This could represent a true difference in epidemiology in rural settings compared to referral facilities in urban settings. Patients were more likely to receive an operation in a hospital with a general surgeon as opposed to a general practitioner. This provides evidence to support increasing the surgical workforce in district hospitals in order to increase surgical availability for patients. PMID- 29191201 TI - Single versus double row suture anchor fixation for greater tuberosity fractures a biomechanical study. AB - BACKGROUND: Fractures of the humeral greater tuberosity (GT) are a frequent injury progressively treated with arthroscopic suture anchor repair. Yet, no biomechanical study has been performed comparing fixation strength of arthroscopic single- (SR) vs. double row (DR) fixation. METHODS: Standardized fractures of the greater tuberosity were created in 12 fresh frozen proximal humeri. After random assignation to the SR or DR group the fixed humeri were tested applying cyclic loading to the supraspinatus and infraspinatus tendon. Load to failure and fragment displacement were assessed by means of an electrodynamic material testing machine using an optical tracking system. RESULTS: Load to failure values were higher in the DR group (649 N; +/-176) than in the SR group (490 N; +/-145) however without statistical significance (p = .12). In greater tuberosity displacement of 3-5 mm surgical treatment is recommended. The fixing constructs in this study did not reach displacement landmarks of 3 or 5 mm before construct failure as shown in previous studies. Thus the applied traction force (N) at 1 mm displacement was analyzed. In the SR group the load at 1 mm displacement was 277 N; +/-46 compared to 260 N; +/-62 in the DR group (p = .65). CONCLUSION: The results suggest that both techniques are viable options for refixation of greater tuberosity fractures. LEVEL OF EVIDENCE: Laboratory study. PMID- 29191202 TI - Evaluation of an accelerated hydrogen peroxide disinfectant to inactivate porcine epidemic diarrhea virus in swine feces on aluminum surfaces under freezing conditions. AB - BACKGROUND: Since its emergence in 2013, porcine epidemic diarrhea virus (PEDV) spread rapidly throughout the country due, in part, to contaminated livestock trailers. The objective of this study was to test the efficacy of an accelerated hydrogen peroxide (AHP) disinfectant for inactivating PEDV in swine feces on metal surfaces under freezing conditions. One 15.24 X 15.24 X 2.54 cm aluminum coupon, contaminated with swine feces, and randomly matched to one pig was the experimental unit. Eight treatment groups representing two AHP concentrations (1:16 and 1:32) in a 10% propylene glycol solution, two contact times in a -10 degrees C freezer (40 min and 60 min), and two levels of fecal contamination (5 mL and 10 mL) in addition to negative and positive control groups were evaluated. Forty 3-week-old pigs, intragastrically inoculated with the contents of the coupons after treatment, were used as a bioassay to determine the infectivity of PEDV after treatment. Infectivity was determined by detection of virus with a nucleocapsid (N) gene-based quantitative real-time reverse transcription polymerase chain reaction (RT-qPCR) on rectal swabs collected from the inoculated pigs on days three and seven post-inoculation. RESULTS: All post-treatment swabs from the negative control coupons were negative for PEDV via RT-qPCR. All post treatment swabs collected from coupons in the AHP disinfectant treatment groups and the positive control group were positive for PEDV via RT-qPCR. For the bioassay, no rectal swabs from pigs in the negative control (0 of 4) or the AHP disinfectant treatment groups (0 of 32) were positive for PEDV. Rectal swabs from all pigs within the positive control group (4 of 4) were positive for PEDV by RT qPCR. CONCLUSIONS: Under the conditions of this study, 1:16 and 1:32 dilutions of the AHP disinfectant successfully inactivated PEDV in swine feces on metal surfaces when applied at -10 degrees C with 40 or 60 min of contact time. This study also suggests that a positive RT-qPCR result for PEDV on an environmental sample should be expected when the AHP disinfectant is applied under freezing conditions, but does not necessarily indicate that an infectious dose of PEDV remains after disinfection. PMID- 29191203 TI - What do US and Canadian parents do to encourage or discourage physical activity among their 5-12 Year old children? AB - BACKGROUND: Parents have the potential to substantively influence their child's physical activity. This study identified the parenting practices of US and Canadian parents to encourage or discourage their 5-12 year-old child's physical activity and to examine differences in parenting practices by country, parental sex, age of child, and income. METHODS: The sample consisted of 134 US and Canadian parents (54.5% US; 60.4% female) recruited from a web-based panel by a polling firm. The parents answered open-ended questions about what they and other parents do to encourage or discourage their child to be active. Responses were coded using a scheme previously developed to code items used in the published literature. Coded responses were summarized by domain and dimension with differences in responses by country, parental sex, age of child, or household income assessed with a log-linear analysis. RESULTS: The 134 parents provided 649 and 397 responses to ways that parents encourage or discourage their child's physical activity, respectively. Over 70% of responses for practices that encourage physical activity were related to structure of the environment, parental encouragement, and co-participation. The most common response was co participation in activity with the child. Of the practices that discourage physical activity, 67% were related to structure of the environment, lack of parental control, and modeling poor behaviors. The most common response was allowing screen time. There were no differences in response by country, parental sex, child age, or household income. CONCLUSIONS: Parents most often encouraged physical activity through structure and emotional support and discouraged physical activity through lack of structure and control. Understanding how parents influence their child's physical activity may help improve intervention strategies. The current results will inform the development of a physical activity parenting practices instrument.

PMID- 29191205 TI - Different effects of cardiac and diaphragm function assessed by ultrasound on extubation outcomes in difficult-to-wean patients: a cohort study. AB - BACKGROUND: Ultrasound is a convenient tool to evaluate cardiac and diaphragm function. The ratio (E/Ea) of mitral Doppler inflow velocity to annular tissue Doppler wave velocity by transthoracic echocardiography (TTE) and diaphragmatic excursion (DE) by diaphragm ultrasound have been confirmed in predicting extubation outcomes independently, however their different roles in the weaning process have not been determined until now. METHODS: We designed a cohort study to preform diaphragm ultrasound and TTE before and after the spontaneous breathing trial (SBT) in difficult-to-wean patients. Patients considered for enrollment should succeed on a SBT and have been extubated. They were followed up with the events of respiratory failure within 48 h, and divided into the respiratory failure and extubation success subgroups. Relevant risk factors predicting respiratory failure were analysed by a multivariate logistic regression model. Then, each subgroup was assessed with respect to re-intubation within 1 week, and divided into the re-intubation and non-intubation subgroups. Furthermore, relevant risk factors predicting re-intubation were also analysed in each subgroup. The area under the curve (AUC) and optimum cut-off value were identified by the receiver operating characteristic curve. RESULTS: Among 60 patients, 29 cases developed respiratory failure within 48 h, and 14 cases were re-intubated or died within 1 week, respectively. Multivariate logistic regression analysis showed that E/Ea (average) after SBT [odds ratio (OR) 1.450, 95% confidence intervals (CI) 1.092-1.926, P = 0.01] and left ventricular ejection fraction were associated with respiratory failure. The AUC of E/Ea (average) after SBT was 0.789, and a cut-off value >= 12.5 showed the highest diagnostic accuracy with a sensitivity and specificity of 72.4% and 77.4%, respectively. Furthermore, in the respiratory failure subgroup only DE (average) after SBT was associated with re-intubation (OR 0.690, CI 0.499-0.953, P = 0.024). The AUC of DE (average) after SBT was 0.805, and a cut-off value <= 12.6 mm showed the highest diagnostic accuracy with a sensitivity and specificity of 80% and 68.4%, respectively. CONCLUSIONS: E/Ea (average) after SBT could help predict respiratory failure within 48 h. However, DE (average) after SBT could help predict re-intubation within 1 week in the respiratory failure subgroup. PMID- 29191206 TI - Optimized CEST cardiovascular magnetic resonance for assessment of metabolic activity in the heart. AB - BACKGROUND: Previous studies have linked cardiac dysfunction to loss of metabolites in the creatine kinase system. Chemical exchange saturation transfer (CEST) is a promising metabolic cardiovascular magnetic resonance (CMR) imaging technique and has been applied in the heart for creatine mapping. However, current limitations include: (a) long scan time, (b) residual cardiac and respiratory motion, and (c) B0 field variations induced by respiratory motion. An improved CEST CMR technique was developed to address these problems. METHODS: Animals with chronic myocardial infarction (N = 15) were scanned using the proposed CEST CMR technique and a late gadolinium enhancement (LGE) sequence as reference. The major improvements of the CEST CMR technique are: (a) Images were acquired by single-shot FLASH, significantly increasing the scan efficiency. (b) All images were registered to reduce the residual motion. (c) The acquired Z spectrum was analyzed using 3-pool-model Lorentzian-line fitting to generate CEST signal, reducing the impact of B0 field shifting due to respiratory motion. Feasibility of the technique was tested in a porcine model with chronic myocardial infarction. CEST signal was measured in the scar, border zone and remote myocardium. Initial studies were performed in one patient. RESULTS: In all animals, healthy remote myocardial CEST signal was elevated (0.16 +/- 0.02) compared to infarct CEST signal (0.09 +/- 0.02, P < 0.001) and the border zone (0.12 +/- 0.02, P < 0.001). For both animal and patient studies, the hypointense regions in the CEST contrast maps closely match the bright areas in the LGE images. CONCLUSIONS: The proposed CEST CMR technique was developed to address long scan times, respiratory and cardiac motion, and B0 field variations. Lower CEST signal in bright region of the LGE image is consistent with the fact that myocardial infarction has reduced metabolic activity. PMID- 29191207 TI - Medical subdomain classification of clinical notes using a machine learning-based natural language processing approach. AB - BACKGROUND: The medical subdomain of a clinical note, such as cardiology or neurology, is useful content-derived metadata for developing machine learning downstream applications. To classify the medical subdomain of a note accurately, we have constructed a machine learning-based natural language processing (NLP) pipeline and developed medical subdomain classifiers based on the content of the note. METHODS: We constructed the pipeline using the clinical NLP system, clinical Text Analysis and Knowledge Extraction System (cTAKES), the Unified Medical Language System (UMLS) Metathesaurus, Semantic Network, and learning algorithms to extract features from two datasets - clinical notes from Integrating Data for Analysis, Anonymization, and Sharing (iDASH) data repository (n = 431) and Massachusetts General Hospital (MGH) (n = 91,237), and built medical subdomain classifiers with different combinations of data representation methods and supervised learning algorithms. We evaluated the performance of classifiers and their portability across the two datasets. RESULTS: The convolutional recurrent neural network with neural word embeddings trained medical subdomain classifier yielded the best performance measurement on iDASH and MGH datasets with area under receiver operating characteristic curve (AUC) of 0.975 and 0.991, and F1 scores of 0.845 and 0.870, respectively. Considering better clinical interpretability, linear support vector machine-trained medical subdomain classifier using hybrid bag-of-words and clinically relevant UMLS concepts as the feature representation, with term frequency-inverse document frequency (tf-idf)-weighting, outperformed other shallow learning classifiers on iDASH and MGH datasets with AUC of 0.957 and 0.964, and F1 scores of 0.932 and 0.934 respectively. We trained classifiers on one dataset, applied to the other dataset and yielded the threshold of F1 score of 0.7 in classifiers for half of the medical subdomains we studied. CONCLUSION: Our study shows that a supervised learning-based NLP approach is useful to develop medical subdomain classifiers. The deep learning algorithm with distributed word representation yields better performance yet shallow learning algorithms with the word and concept representation achieves comparable performance with better clinical interpretability. Portable classifiers may also be used across datasets from different institutions. PMID- 29191208 TI - Emotional distress and dysfunctional illness perception are associated with low mental and physical quality of life in Chinese breast cancer patients. AB - BACKGROUND: To evaluate the relationship between quality of life (QOL) and physical as well as psychological variables in Chinese breast cancer patients. METHODS: This multicenter cross-sectional study enrolled 254 Chinese breast cancer patients in different stages and treatment phases. They answered standard instruments assessing QOL (EORTC), somatic symptom severity (PHQ-15), depression (PHQ-9), anxiety (GAD-7), health-related anxiety (WI-7), illness perception (BIPQ), and sense of coherence (SOC-9). Canonical correlation was applied to identify the strongest correlates between the physical, emotional and social QOL scales and the physical and psychological variables. RESULTS: In our sample, a low global QOL was significantly associated with the following physical and psychological variables: symptom-related disability (Karnofsky Index) (r = .211, p < .01), somatic symptom severity (r = -.391, p < .001), depression (r = -.488, p < .001), anxiety (r = -.439, p < .001), health-related anxiety (r = -.398, p < .001), dysfunctional illness perception (r = -.411, p < .001), and sense of coherence (r = .371, p < .001). In the canonical correlation analysis, high somatic symptom severity, depression, anxiety, dysfunctional illness perception, and low sense of coherence showed the strongest correlations with low physical, emotional and social functioning. The first three significant canonical correlations between these two sets of variables were .78, .56, and .45. CONCLUSIONS: QOL in Chinese breast cancer patients is strongly associated with psychological factors. Our results suggest that Chinese physicians and nurses should incorporate these factors into their care for women with breast cancer to improve patients' QOL.

AB - OBJECTIVE: This study investigated an outbreak of Bartonellosis in a coastal region in Peru. RESULTS: A total of 70 (n = 70) samples with clinical criteria for the acute phase of Bartonellosis and a positive peripheral blood smear were included. 22.85% (n = 16) cases of the samples were positive for Bartonella bacilliformis by PCR and automatic sequencing. Of those positive samples, 62.5% (n = 10) cases were positive only for B. bacilliformis and 37.5% (n = 6) cases were positive to both Mycobacterium spp. and B. bacilliformis. The symptom frequencies were similar in patients diagnosed with Carrion's disease and those co-infected with Mycobacterium spp. The most common symptoms were headaches, followed by malaise and arthralgia. PMID- 29191210 TI - New clues to the nature of immunoglobulin G4-related disease: a retrospective Japanese multicenter study of baseline clinical features of 334 cases. AB - BACKGROUND: The aim was to further characterize immunoglobulin G4-related disease (IgG4-RD) by a large-scale multicenter study of its clinical and laboratory features conducted by multidisciplinary physicians of IgG4-RD in Japan. METHODS: Various specialists retrospectively evaluated IgG4-RD patients diagnosed between 1996 and 2015 in five hospitals by analyzing their baseline clinical features, laboratory, imaging, and pathological test findings, and treatment. RESULTS: Of the 334 patients listed, 205 were male and median age at diagnosis was 65 years. The mean number of organs involved was 3.2 at diagnosis. The most frequently affected organs were the salivary glands, followed by the lacrimal glands, lymph nodes, pancreas, retroperitoneum/periaorta, kidneys, and lungs. The mean serum level of IgG4 was 755 mg/dl, and more than 95% of patients had elevated serum IgG4 levels. The median serum level of C-reactive protein (CRP) was 0.1 mg/dl and the level was less than 1 mg/dl in 90% of patients. A total of 34.7% of patients had low serum levels of C3. Serum levels of C3 and non-IgG4 IgG, calculated as the total IgG minus IgG4, showed an inverse correlation in patients with kidney lesions, while serum IgG4 levels were not correlated with serum C3 levels. Corticosteroid was administered in 78.0% of patients, and was effective in all. CONCLUSIONS: The serum CRP level is generally low and the serum IgG4 level is elevated in most Japanese IgG4-RD patients, in contrast to western patients. These original findings suggest that these two parameters in IgG4-RD differ in some interesting ways from those hitherto reported in western populations. Additional studies, especially international comparative ones, are needed to elucidate the extent and significance of these differences between populations. Attention will also have to be paid to whether the existence of such differences requires consideration when devising international classification criteria. PMID- 29191211 TI - Unexpected pulmonary tumor: metastasis from a benign uterine leiomyoma in a post menopausal woman: a case report. AB - BACKGROUND: The occurrence of lung metastasis from benign uterine leiomyomas is rarely reported especially in post menopausal women. The pathogenesis of these metastatic benign tumors still remains a subject of various speculations. CASE PRESENTATION: A 57-year-old woman presented with a chronic cough and dyspnea. She had undergone 8 years previously, hysterectomy for benign leiomyomas. A chest computed tomography scan showed a 4 cm solitary nodular parenchymal tumor that increased in size after 12 months. The histological analysis of the biopsy from this nodule showed a benign tumor with regular spindle cells disposed in intersected fascicles. At immunohistochemical analysis, the tumor cells were positive for smooth muscle markers and oestrogen-progesterone receptors with a low mitotic index assessed by Ki-67. These features were consistent with a benign metastasizing uterine leiomyoma. At the multidisciplinary meeting, prescription of an aromatase inhibitor has been decided for the patient. CONCLUSIONS: Benign metastasizing uterine leiomyomas of the lung are very rare tumors. Although extremely rare in post menopausal women, their diagnosis should be considered in symptomatic patients with a history of hysterectomy for leiomyomas. PMID- 29191212 TI - Involuntary protection against dermatosis: A preliminary observation on trypophobia. AB - OBJECTIVE: Trypophobia refers to the intense negative emotions evoked by exposure to repeated visual patterns like a honeycomb. We propose a cognitive mechanism that can explain why such negative emotions are triggered by trypophobic objects, primarily through automatic and involuntary avoidance of skin diseases, which is also called as the Involuntary Protection Against Dermatosis (IPAD) hypothesis. RESULTS: We asked 856 participants to evaluate the discomfort evoked by trypophobic images and to report their past and current skin-related medical problems. Results showed that participants with a history of skin problems rated the pictures as evoking high discomfort as compared to those without skin problems. We conducted another survey to replicate the original survey using additional 690 participants, which confirmed the reliability of the current findings. The current study presents preliminary observational data that supports the IPAD hypothesis and suggests ways to reduce maladaptive emotional reactions toward trypophobic objects. PMID- 29191213 TI - Modified pedicle screw-rod fixation versus anterior pelvic external fixation for the management of anterior pelvic ring fractures: a comparative study. AB - BACKGROUND: Anterior pelvic ring fracture, as high-energy trauma, needs to be effectively treated. The purpose of the current study was to evaluate the clinical applications of modified pedicle screw-rod fixation and anterior pelvic external fixation for the treatment of anterior pelvic ring fracture. METHODS: Either modified pedicle screw-rod fixation (modified PSRF group, N = 21) or anterior pelvic external fixation (APEF group, N = 22) was performed to 43 patients, with or without fixation of posterior ring. Clinical outcomes were evaluated via Majeed scores. Relevant clinical evaluation indicators including operation time, intraoperative blood loss, hospitalization duration, and complications were compared between these two groups. RESULTS: The operation time in APEF group was significantly less than that in modified PSRF group (P < 0.0001). No significant difference with respect to intraoperative blood loss and hospitalization duration between the two groups was shown (P = 0.51 and P = 0.33, respectively). Six patients developed surgical site infection in APEF group. Three patients experienced loss of fixation, and two patients experienced loosening of fixator in APEF group. Temporary lateral femoral cutaneous nerve irritation occurred in three patients in modified PSRF group while two patients in APEF group. One patient experienced femoral nerve palsy in modified PSRF group. Fractures of all patients healed well eventually. No statistical difference regarding Majeed evaluation scores was found between two groups. CONCLUSIONS: Application of both modified PSRF and APEF could provide similar satisfactory clinical outcomes for anterior pelvic ring fracture. Modified PSRF, a minimally invasive technique with the advantages of internal fixation, could be performed as an alternative method for instable pelvic fractures.

PMID- 29191214 TI - The role of aberrant expression of T cell miRNAs affected by TNF-alpha in the immunopathogenesis of rheumatoid arthritis. AB - BACKGROUND: Tumor necrosis factor-alpha (TNF-alpha) can cause diverse T cell dysfunctions in patients with rheumatoid arthritis (RA). It is involved in the regulation of microRNAs (miRNAs) expression in different cell types. We hypothesized that the expression of T cell miRNAs would be affected by TNF-alpha, and these miRNAs could participate in the immunopathogenesis of RA. METHODS: Expression profiles of 270 human miRNAs in Jurkat cells, cultured in the presence or absence of TNF-alpha for 7 days were analyzed by real-time polymerase chain reaction. Potentially aberrantly expressed miRNAs were validated using T cell samples from 35 patients with RA and 15 controls. Transfection studies were conducted to search for gene expression and biological functions regulated by specific miRNAs. RESULTS: Initial analysis revealed 12 miRNAs were significantly lower, whereas the expression level of miR-146a was significantly higher in Jurkat cells after being cultured with TNF-alpha for 7 days. Decreased expression of miR-139-3p, miR-204, miR-760, miR-524-5p, miR-136, miR-548d-3p, miR-214, miR 383, and miR-887 were noted in RA T cells. Expression levels of miR-139-3p, miR 204, miR-214, and miR-760 were correlated with the use of biologic agents. The transfection of miR-214 mimic suppressed TNF-alpha-mediated apoptosis of Jurkat cells. Increased phosphorylation of extracellular regulating kinase (ERK) and c Jun N-terminal kinase (JNK) was noted in RA T cells and Jurkat cells after TNF alpha exposure. Transfection of Jurkat cells with miR-214 mimic suppressed both the basal and TNF-alpha-mediated ERK and JNK phosphoryation. CONCLUSIONS: Among T cell miRNAs affected by TNF-alpha, the expression levels of nine miRNAs were decreased in T cells from patients with RA. The expression levels of miR-139-3p, miR-204, miR-214, and miR-760 increased in RA patients receiving biologic agents. The transfection of miR-214 reversed the TNF-alpha-mediated cells apoptosis and inhibited the phosphorylation of ERK and JNK in Jurkat cells. PMID- 29191215 TI - Domestication of self-splicing introns during eukaryogenesis: the rise of the complex spliceosomal machinery. AB - : ?: The spliceosome is a eukaryote-specific complex that is essential for the removal of introns from pre-mRNA. It consists of five small nuclear RNAs (snRNAs) and over a hundred proteins, making it one of the most complex molecular machineries. Most of this complexity has emerged during eukaryogenesis, a period that is characterised by a drastic increase in cellular and genomic complexity. Although not fully resolved, recent findings have started to shed some light on how and why the spliceosome originated. In this paper we review how the spliceosome has evolved and discuss its origin and subsequent evolution in light of different general hypotheses on the evolution of complexity. Comparative analyses have established that the catalytic core of this ribonucleoprotein (RNP) complex, as well as the spliceosomal introns, evolved from self-splicing group II introns. Most snRNAs evolved from intron fragments and the essential Prp8 protein originated from the protein that is encoded by group II introns. Proteins that functioned in other RNA processes were added to this core and extensive duplications of these proteins substantially increased the complexity of the spliceosome prior to the eukaryotic diversification. The splicing machinery became even more complex in animals and plants, yet was simplified in eukaryotes with streamlined genomes. Apparently, the spliceosome did not evolve its complexity gradually, but in rapid bursts, followed by stagnation or even simplification. We argue that although both adaptive and neutral evolution have been involved in the evolution of the spliceosome, especially the latter was responsible for the emergence of an enormously complex eukaryotic splicing machinery from simple self-splicing sequences.

PMID- 29191216 TI - COSUMO: study protocol for the development of a core outcome set for efficacy and effectiveness trials in posterior segment-involving uveitis. AB - BACKGROUND: Uveitis, a group of disorders characterised by intraocular inflammation, causes 10-15% of total blindness in the developed world. The most sight-threatening uveitis affects the posterior segment of the eye (posterior segment involving uveitis (PSIU)). Numerous different outcomes have been used in clinical trials evaluating alternative treatments for uveitis, limiting inter trial comparison and aggregation of data. We aim to develop a core outcome set (COS) that would provide a standardised set of outcomes to be measured and reported in all effectiveness trials for PSIU. METHODS: A three-phase design will be used informed by recommendations from the Core Outcome Measures in Effectiveness Trials (COMET) initiative. Phase 1: a comprehensive list of outcomes will be identified through both a systematic review of effectiveness trials of PSIU and qualitative research with stakeholders. The qualitative study will comprise focus groups with patients and their carers in parallel with one-to one telephone interviews with health professionals and policy-makers. In the focus groups, patients will be grouped according to whether or not their uveitis is complicated by the sight-threatening condition uveitic macular oedema (UMO) since it is hypothesised that the presence of UMO may significantly impact on patient experience of PSIU. Phase 2: Delphi methodology will be used to reduce the range of potential outcomes for the core set. Up to three Delphi rounds will be used through an online survey. Participants will be asked to rate the importance of each outcome on a 9-point Likert scale where 9 is most important. Phase 3: a consensus meeting will be held with key stakeholders to discuss the Delphi results and ratify the final outcomes to be included in the COS. DISCUSSION: The development of an agreed COS for PSIU would help ensure that outcomes which matter to key stakeholders are captured and reported in a consistent way. A COS for PSIU would allow greater comparison and aggregation of data across trials for the better evaluation of established and emerging therapies through evidence synthesis and meta-analysis to inform clinical guidelines and health policy.

PMID- 29191217 TI - Multi-level comparisons of cloacal, skin, feather and nest-associated microbiota suggest considerable influence of horizontal acquisition on the microbiota assembly of sympatric woodlarks and skylarks. AB - BACKGROUND: Working toward a general framework to understand the role of microbiota in animal biology requires the characterisation of animal-associated microbial communities and identification of the evolutionary and ecological factors shaping their variation. In this study, we described the microbiota in the cloaca, brood patch skin and feathers of two species of birds and the microbial communities in their nest environment. We compared patterns of resemblance between these microbial communities at different levels of biological organisation (species, individual, body part) and investigated the phylogenetic structure to deduce potential microbial community assembly processes. RESULTS: Using 16S rRNA gene amplicon data of woodlarks (Lullula arborea) and skylarks (Alauda arvensis), we demonstrated that bird- and nest-associated microbiota showed substantial OTU co-occurrences and shared dominant taxonomic groups, despite variation in OTU richness, diversity and composition. Comparing host species, we uncovered that sympatric woodlarks and skylarks harboured similar microbiota, dominated by Proteobacteria, Firmicutes, Actinobacteria, Bacteroidetes and Acidobacteria. Yet, compared with the nest microbiota that showed little variation, each species' bird-associated microbiota displayed substantial variation. The latter could be partly (~ 20%) explained by significant inter-individual differences. The various communities of the bird's body (cloaca, brood patch skin and feathers) appeared connected with each other and with the nest microbiota (nest lining material and surface soil). Communities were more similar when the contact between niches was frequent or intense. Finally, bird microbiota showed significant phylogenetic clustering at the tips, but not at deeper branches of the phylogeny. CONCLUSIONS: Our interspecific comparison suggested that the environment is more important than phylogeny in shaping the bird-associated microbiotas. In addition, variation among individuals and among body parts suggested that intrinsic or behavioural differences among females and spatial heterogeneity among territories contributed to the microbiome variation of larks. Modest but significant phylogenetic clustering of cloacal, skin and feather microbiotas suggested weak habitat filtering in these niches. We propose that lark microbiota may be primarily, but not exclusively, shaped by horizontal acquisition from the regional bacterial pool at the breeding site. More generally, we hypothesise that the extent of ecological niche-sharing by avian (or other vertebrate) hosts may predict the convergence of their microbiota. PMID- 29191218 TI - Analysis of choroidal and central foveal thicknesses in acute anterior uveitis by enhanced-depth imaging optical coherence tomography. AB - BACKGROUND: Currently, there are a limited number of reports of structural changes in the retina and choroid in acute anterior uveitis (AAU). The aim of this study was to evaluate choroidal and central foveal thicknesses during episodes of AAU. METHODS: The medical records of 120 patients with AAU and 120 healthy subjects matched for age, sex, and spherical equivalent of refractive error were reviewed. Subjects were divided into group 1 (AAU-affected eyes), 2 (unaffected fellow eyes), and 3 (healthy control eyes). RESULTS: In the uveitis group, etiologic diagnoses included human leukocyte antigen (HLA)-B27-associated (n = 71) and idiopathic (n = 49) AAU. The mean subfoveal choroidal thicknesses (SFCTs) in groups 1-3 were 326.7 +/- 64.2, 296.1 +/- 66.6, and 294.9 +/- 41.7 MUm, respectively. The corresponding mean central foveal thicknesses (CFTs) were 273.5 +/- 29.3, 264.4 +/- 24.6, and 263.0 +/- 30.8 MUm, respectively. The AAU group exhibited a significantly greater SFCT than the control groups (P < .001). Relative to the control group, while eyes with idiopathic AAU exhibited a significantly greater CFT, those with HLA-B27-associated AAU exhibited no such significant difference. Anterior chamber cell grade was not associated with SFCT or CFT. CONCLUSIONS: The SFCT increased significantly during AAU. This indicates the importance of OCT examination for detection of subclinical choroidal and retinal changes in all types of AAU. PMID- 29191220 TI - Type IV dual left anterior descending coronary artery: a case report. AB - BACKGROUND: Dual left anterior descending (LAD) artery or duplication of LAD is a rarely reported coronary anomaly, consisting of two branches supplying the usual distribution of the LAD. Type IV dual LAD, in which a short LAD arises from the left main coronary artery and a long LAD arises from the right coronary artery is remarkably rare, and has not been reported in a Bangladeshi subject. CASE PRESENTATION: We describe the case of a 70-year old Bangladeshi male who presented with breathlessness in the background of a prior inferior myocardial infarction. Coronary angiography revealed an anomalous dual LAD. The short LAD which arose from the left main coronary artery gave off the first septal branch and terminated after giving off a large diagonal branch which continued further down towards the apex. The long LAD arose from the proximal right coronary artery and after traversing a distance, arrived at the interventricular septum, terminating at the apex after giving off diagonal branches. The right coronary artery was totally occluded from its early mid part and well-collateralized with retrograde flow from the left system. CONCLUSION: We describe a case with unique variation of dual LAD type IV, which has previously not been described in a Bangladeshi subject thus far. Coronary angiography is vital to determine this coronary anomaly, which is usually detected incidentally on routine angiography for chest pain, sometimes with involvement of significant lesion of other coronary arteries, as in this case. PMID- 29191221 TI - Increased synovial lipodystrophy induced by high fat diet aggravates synovitis in experimental osteoarthritis. AB - BACKGROUND: Metabolic syndrome (MetS) may be associated with knee osteoarthritis (OA), but the association between the individual components and OA are not well understood. We aimed to study the effect of hypercholesterolemia on synovial inflammation in knee OA. METHODS: OA was surgically induced in rabbits fed with standard diet (OA group, n = 10) or in rabbits fed with high fat diet (OA-HFD, n = 10). Healthy rabbits receiving standard diet (Control, n = 10) or fed with HFD (HFD, n = 6) were also monitored. Twelve weeks after OA induction, synovial membranes were isolated and processed for studies. RESULTS: Animals fed HFD showed higher levels of total serum cholesterol, triglycerides and C-reactive protein than control rabbits. Twelve weeks after OA induction, synovial membrane inflammation and macrophage infiltration were increased in rabbits with OA, particularly in the OA-HFD group. Extensive decrease of synovial adipose tissue area, adipocyte size and perilipin-1A synthesis were observed in the OA-HFD group in comparison to the OA and control groups. The HFD further increased the proinflammatory mediators IL-1beta, IL-6 and TNF in the OA synovium. However, the synovial gene expression of adipokines, such as leptin and adiponectin, were markedly decreased in the rabbits with OA, especially in the OA-HFD group, in correlation with adipose tissue loss. However, circulating leptin was upregulated in the HFD and OA-HFD groups. CONCLUSION: Our results indicate that a HFD is an aggravating factor worsening synovial membrane inflammation during OA, guided by increased infiltration of macrophages and removal of the adipose tissue, together with a remarkable presence of proinflammatory factors. Synovial adipocytes and dyslipemia could probably play pivotal roles in OA joint deterioration in patients with MetS, supporting that the link between obesity and OA transcends mechanical loading. PMID- 29191219 TI - Neurons derived from sporadic Alzheimer's disease iPSCs reveal elevated TAU hyperphosphorylation, increased amyloid levels, and GSK3B activation. AB - BACKGROUND: Alzheimer's disease (AD) is the most common type of dementia, affecting one in eight adults over 65 years of age. The majority of AD cases are sporadic, with unknown etiology, and only 5% of all patients with AD present the familial monogenic form of the disease. In the present study, our aim was to establish an in vitro cell model based on patient-specific human neurons to study the pathomechanism of sporadic AD. METHODS: We compared neurons derived from induced pluripotent stem cell (iPSC) lines of patients with early-onset familial Alzheimer's disease (fAD), all caused by mutations in the PSEN1 gene; patients with late-onset sporadic Alzheimer's disease (sAD); and three control individuals without dementia. The iPSC lines were differentiated toward mature cortical neurons, and AD pathological hallmarks were analyzed by RT-qPCR, enzyme-linked immunosorbent assay, and Western blotting methods. RESULTS: Neurons from patients with fAD and patients with sAD showed increased phosphorylation of TAU protein at all investigated phosphorylation sites. Relative to the control neurons, neurons derived from patients with fAD and patients with sAD exhibited higher levels of extracellular amyloid-beta 1-40 (Abeta1-40) and amyloid-beta 1-42 (Abeta1-42). However, significantly increased Abeta1-42/Abeta1-40 ratios, which is one of the pathological markers of fAD, were observed only in samples of patients with fAD. Additionally, we detected increased levels of active glycogen synthase kinase 3 beta, a physiological kinase of TAU, in neurons derived from AD iPSCs, as well as significant upregulation of amyloid precursor protein (APP) synthesis and APP carboxy-terminal fragment cleavage. Moreover, elevated sensitivity to oxidative stress, as induced by amyloid oligomers or peroxide, was detected in both fAD- and sAD-derived neurons. CONCLUSIONS: On the basis of the experiments we performed, we can conclude there is no evident difference except secreted Abeta1 40 levels in phenotype between fAD and sAD samples. To our knowledge, this is the first study in which the hyperphosphorylation of TAU protein has been compared in fAD and sAD iPSC-derived neurons. Our findings demonstrate that iPSC technology is suitable to model both fAD and sAD and may provide a platform for developing new treatment strategies for these conditions. PMID- 29191222 TI - Magico-religious and social belief of tribals of district Udaipur, Rajasthan. AB - BACKGROUND: Religious beliefs and practices have long influenced human perceptions and uses of nature. Animals in particular play a prominent role in magico-religious practices and provide historical and cultural depth of these relationships. Understanding human-faunal relations is often fundamental to the cause of meaningful wildlife conservation. This study investigates the domestic and wild harvested species used for spiritual and religious purposes among the tribals of six tehsils of Udaipur district. METHODS: The ethnozoological data were obtained by an emic approach, applying different tools such as semi structured interviews, participatory rural appraisal, key informant interviews, and focus group discussions. The scientific name and species of animals were identified using relevant and standard literature. Present investigation is a part of major concept worked out for study on tribal people and their beliefs. Ethnozoological information was collected by interview of 150 tribals. The questionnaire was prepared in Hindi keeping all parameters in mind. A total of 55 respondents (35 males and 20 females) answered to the magico-religious parameter. The collected data were analyzed through informant fidelity level (FL). RESULTS: The present study was undertaken to have an insight of the ethnozoological uses of animals prevalent in Bhil, Meena, and Kathodi tribes inhabiting the Udaipur district of Rajasthan. A total of 25 animals used for magico-religious and social purposes were recorded from the study area. Out of the total number of animals, 60% (15) were mammals, 24% (6) were birds, 12% (3) were reptiles, and the rest 4% (1) were the mollusks. Of the total ethnozoological practices, 64% fall in the magico-religious category, 12% in socio-cultural category, 12% in the category of ethnomusical, and 12% in the category of taboos. CONCLUSIONS: The tribal people maintain strong ties with animals at both the material and spiritual level. Study reveals that traditional people depend on local therapies either magico-religious or natural ones in absence of awareness, modern medical facilities, expensive drugs, and poor transportation. However, the use of animal material in such practices is on a decline. PMID- 29191223 TI - Resistin upregulates chemokine production by fibroblast-like synoviocytes from patients with rheumatoid arthritis. AB - BACKGROUND: Adipokines are bioactive hormones secreted by adipose tissues. Resistin, an adipokine, plays important roles in the regulation of insulin resistance and inflammation. Resistin levels are known to be increased in the serum and synovial fluid of rheumatoid arthritis (RA) patients. However, the pathogenic role of resistin in RA has not yet been elucidated. METHODS: The expression of resistin and adenylate cyclase-associated protein 1 (CAP1), a receptor for resistin, was examined immunohistochemically in synovial tissue. CAP1 expression in in vitro cultured fibroblast-like synoviocytes (FLSs) was assessed with a reverse transcription-polymerase chain reaction (PCR) and western blotting. The gene expression of resistin-stimulated FLSs was evaluated by RNA sequencing (RNA-Seq) and quantitative real-time PCR. Concentrations of chemokine (C-X-C motif) ligand (CXCL) 8, chemokine (C-C motif) ligand (CCL) 2, interleukin (IL)-1beta, IL-6 and IL-32 in culture supernatants were measured by enzyme-linked immunosorbent assay. Small interfering RNA (siRNA) for CAP1 was transfected into FLSs in order to examine inhibitory effects. RESULTS: The expression of resistin and CAP1 in synovial tissue was stronger in RA than in osteoarthritis (OA). Resistin was expressed by macrophages in the RA synovium, while CAP1 was expressed by macrophages, FLSs and endothelial cells. In vitro cultured RA FLSs also expressed CAP1. RNA-Seq revealed that the expression levels of 18 molecules were more than twofold higher in resistin-stimulated FLSs than in unstimulated FLSs. Seven chemokines, CXCL1, CXCL2, CXCL3, CXCL5, CXCL6, CXCL8, and CCL2, were included among the 18 molecules. Increases induced in the expression of CXCL1, CXCL8, and CCL2 by the resistin stimulation were confirmed by real-time PCR. The stimulation with resistin increased the protein levels of CXCL8 and CCL2 produced by RA FLSs, and the upregulated expression of CXCL8 was inhibited by the abrogation of CAP1 by siRNA for CAP1. Production of IL-6 by FLSs was also increased by resistin. Expression of IL-1beta and IL-32 was not detected by ELISA. CONCLUSIONS: Resistin contributes to the pathogenesis of RA by increasing chemokine production by FLSs via CAP1 in synovial tissue. PMID- 29191224 TI - I knew how it feels but couldn't save my daughter; testimony of an Ethiopian mother on female genital mutilation/cutting. AB - BACKGROUND: World Health Organization defines female genital mutilation/cutting as all procedures that involve partial or total removal of the external female genitalia, or other injury to the female genital organs for non-medical reasons. The practice is common in Ethiopia, especially among Somali (99%) ethnic groups. Even though FGM/C is labeled illegal practice according to the revised 2005 Penal Code of the country, the practice is still responsible for misery of many girls in Ethiopia. METHODS: This personal testimony is presented using woman's own words. Data were collected through in-depth interview with a woman at Gursum health center, Somali regional state, eastern Ethiopia on June 19/2016. The interview was conducted in a private environment and original names were changed to overcome ethical concerns. Informed written consent was obtained from the participant prior to data collection. The interview was audio-taped using a digital voice recorder, later transcribed and translated verbatim from the local language, Amharic to English. RESULTS: The study participant described a range of experiences she had during her own and her daughter's circumcision. Three themes emerged from the woman's description: womanhood, social pressure and stigmatization of uncircumcised women and uncertain future. CONCLUSION: Even though the national prevalence may show a decline, FGM/C is still practiced underground. Thus, anti-FGM/C interventions shall take in to account elders influence and incorporate a human rights approach rather than relying merely on the dire health consequences. Further exploration of the determinants of FGM/C on a wider scale is recommended. PMID- 29191226 TI - Antibacterial and antifungal activities and phytochemical profile of leaf extract from different extractants of Ricinus communis against selected pathogens. AB - OBJECTIVES: Ricinus communis leaves are used in herbal preparations for treating candidiasis, skin and wound infections in Ghana. This study aimed at comparing the phytochemical profile of aqueous, methanol, petroleum ether, ethyl acetate and ethanolic extracts of the leaves of Ricinus communis and determine the growth inhibitory activities, bactericidal, bacteriostatic and fungicidal effects of the respective extracts on Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumonaie and Candida albicans. RESULTS: The aqueous, methanol and ethanol extracts were shown to contain most of the phytochemicals analyzed. All solvents extracts exhibited inhibitory activity against the growth of all microorganisms under study. The methanol extract showed highest zones of inhibition and was found to be statistically significant (P < 0.05) compared to other solvents extracts. All solvents extracts exhibited both bacteriostatic and bactericidal effects on the test organisms at varying concentration, with MIC values ranging from 3.13 to 25.0 mg/ml and MBCs were from 200 to 400 mg/ml. MFCs of Candida albicans was between 200 and 400 mg/l. Our data confirm the anti bacterial and anti-fungal properties of R. communis and showed that the biologically relevant phytochemicals from the leaves of this plant can be extracted with the solvents aqueous, methanol and ethanol. PMID- 29191225 TI - Landscape and evolution of tissue-specific alternative polyadenylation across Drosophila species. AB - BACKGROUND: Drosophila melanogaster has one of best-described transcriptomes of any multicellular organism. Nevertheless, the paucity of 3'-sequencing data in this species precludes comprehensive assessment of alternative polyadenylation (APA), which is subject to broad tissue-specific control. RESULTS: Here, we generate deep 3'-sequencing data from 23 developmental stages, tissues, and cell lines of D. melanogaster, yielding a comprehensive atlas of ~ 62,000 polyadenylated ends. These data broadly extend the annotated transcriptome, identify ~ 40,000 novel 3' termini, and reveal that two-thirds of Drosophila genes are subject to APA. Furthermore, we dramatically expand the numbers of genes known to be subject to tissue-specific APA, such as 3' untranslated region (UTR) lengthening in head and 3' UTR shortening in testis, and characterize new tissue and developmental 3' UTR patterns. Our thorough 3' UTR annotations permit reassessment of post-transcriptional regulatory networks, via conserved miRNA and RNA binding protein sites. To evaluate the evolutionary conservation and divergence of APA patterns, we generate developmental and tissue-specific 3'-seq libraries from Drosophila yakuba and Drosophila virilis. We document broadly analogous tissue-specific APA trends in these species, but also observe significant alterations in 3' end usage across orthologs. We exploit the population of functionally evolving poly(A) sites to gain clear evidence that evolutionary divergence in core polyadenylation signal (PAS) and downstream sequence element (DSE) motifs drive broad alterations in 3' UTR isoform expression across the Drosophila phylogeny. CONCLUSIONS: These data provide a critical resource for the Drosophila community and offer many insights into the complex control of alternative tissue-specific 3' UTR formation and its consequences for post-transcriptional regulatory networks.

AB - OBJECTIVE: Multidrug-resistant tuberculosis (MDR-TB) case finding progressively increased in Ethiopia mainly as a result of the utilization of World Health Organization (WHO)-endorsed rapid technologies including MTBDRplus assay. However, there is inadequate data on routine testing performance of the MTBDRplus assay. Consequently, the aim of the study was to assess the routine performance of the MTBDRplus assay in detecting MDR-TB at St. Peter's TB Specialized Hospital. RESULTS: The sensitivity and specificity of MTBDRplus in detecting isoniazid (INH) resistance were 96.3 and 100%, respectively. While for rifampicin (RIF) 100% was recorded for both. Similarly, a sensitivity of 97.96% and a specificity of 100% was measured for detecting MDR-TB. Among 49 MTBDRplus RIF resistant isolates, 46 (93.9%) strains had rpoB mutation. S531L was the most common rpoB mutant (81.6% of RIF resistant cases). All MTBDRplus INH resistant isolates (n = 52) had S315T1 katG mutation. PMID- 29191228 TI - The oncology nurse coordinator: role perceptions of staff members and nurse coordinators. AB - BACKGROUND: There is extensive evidence that the role of nurse coordinators is beneficial for patients. Nurse coordinators are more available to patients compared to general registered nurses, know better to control symptoms and work as team players with multiple care providers. Despite its significance, there is a dearth of literature on the subject in Israel and a lack of clarity regarding the definitions of the role in terms of responsibilities and authorities. The aim of the study is to: To examine how the role of nurse oncology coordinator is implemented in various fields of oncology and to describe the actual performance of different kinds of oncology nurse coordinators and staff perceptions regarding this role in one tertiary hospital in Jerusalem. METHODS: A phenomenological approach was used to explore the participants' experiences and views of nurse coordinators' performance. We conducted a qualitative study using in-depth semi structured interviews. Interviewees included 30 employees from different levels of the hospitals, and leading figures associated with oncology medicine outside of the hospital: Nurses and physicians of the Sharett Oncology Institute of Hadassah Ein Kerem Hospital in Jerusalem, the administrative staff of Hadassah Ein Kerem Hospital, head nurses of the Israel Cancer Association, the chairperson of the Non-Profit Organization of Oncology Nurses, nurse directors at the Ministry of Health Nursing Division, and seven nurse coordinators at Hadassah Ein Kerem Hospital in diverse fields of oncology. RESULTS: The nurse coordinator is perceived as an important staff member providing care to cancer patients. Several key elements were found to be common features in the work of all nurse coordinators: emotional support, guidance to patients, and coordination of patients' care. CONCLUSIONS: The nurse coordinator plays a noteworthy role in the health care system. In view of the variety of roles that the nurse coordinator assumes in different units, performance standards must be adapted to the performance areas for each unit, as well as nurses' professional development requirements. Changes in a service organization and careful attention to the continuum of care highlight the need to develop and to strengthen the role of a nurse who coordinates treatment over the entire continuum of care, both in the hospital and in the community. PMID- 29191229 TI - Medical students as health coaches, and more: adding value to both education and patient care. AB - New ways of thinking about medicine and health care demand new methods in medical education. Over the past two decades, as both the practice and the study of medicine have become increasingly concerned with demonstrable outcomes, medical schools have developed new curricula in health systems science and are increasingly emphasizing students' development and demonstration of skills essential to a systems-based, outcomes-oriented practice environment.Polak and colleagues recently reported the development in Israel of one such curriculum, in lifestyle medicine, that includes opportunities for students to adopt the role of health coach. This commentary describes additional recent curricular developments elsewhere with similar goals, but utilizing more ambitious approaches that embed students in medical practices and provide meaningful, ongoing responsibility for assisting in the care of patients. These emerging new models for ambulatory care education, through a construct known as "value added education," can simultaneously benefit both educational and patient care outcomes. PMID- 29191231 TI - Assessing loss to follow-up in the MObile Technology for Improved Family Planning (MOTIF) randomised controlled trial. AB - BACKGROUND: Loss to follow-up (LTFU) in clinical trials is an important source of bias that can affect statistical power and generalisability of findings. The aim of this paper is to assess factors associated with LTFU in the MObile Technology for Improved Family Planning (MOTIF) trial in Cambodia and compare how the result might have varied using different analytical methods. METHODS: Follow-up in the MOTIF trial was 86% at 4 months and 66% at 12 months. For the primary analysis, we undertook a complete case analysis, similar to the approach used in similar trials of interventions delivered by mobile phone to increase contraception use. We conducted an exploratory analysis and found that factors associated with LTFU were young age, lower socio-economic status, not planning to use post-abortion contraception, availability of phone credit and not providing additional contact numbers. We then undertook two analyses to estimate the effect of the intervention on the primary outcome at 4 and 12 months for comparison with the complete case analysis. First, we undertook multiple imputation, and second we conducted an analysis treating all participants' LTFU as non-users of contraception. RESULTS: Using multiple imputation, we found that the risk ratio was slightly increased at 4 months and slightly decreased at 12 months compared with the complete case analysis. When counting all participants' LTFU as non users of contraception, we observed that, compared with the complete case analysis, the risk ratio was slightly decreased at 4 months and slightly increased at 12 months. Despite the changes in the risk ratio, use of the different analytical methods did not result in an effect using the complete case analysis becoming statistically significant or vice versa. CONCLUSION: Future studies assessing contraception use might anticipate increased attrition amongst younger participants, those of lower socio-economic status or those who do not provide additional contact details. Attrition could be reduced by collecting as many contact details as possible, by providing incentives and possibly by enhanced counselling to groups at higher risk of LTFU on recruitment. Multiple imputation should be considered in addition to complete case analysis if LTFU not missing at random is expected or observed. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01823861 . Registered on 30 March 2013. PMID- 29191230 TI - Implementation fidelity trajectories of a health promotion program in multidisciplinary settings: managing tensions in rehabilitation care. AB - BACKGROUND: Although the importance of evaluating implementation fidelity is acknowledged, little is known about heterogeneity in fidelity over time. This study aims to generate insight into the heterogeneity in implementation fidelity trajectories of a health promotion program in multidisciplinary settings and the relationship with changes in patients' health behavior. METHODS: This study used longitudinal data from the nationwide implementation of an evidence-informed physical activity promotion program in Dutch rehabilitation care. Fidelity scores were calculated based on annual surveys filled in by involved professionals (n = +/- 70). Higher fidelity scores indicate a more complete implementation of the program's core components. A hierarchical cluster analysis was conducted on the implementation fidelity scores of 17 organizations at three different time points. Quantitative and qualitative data were used to explore organizational and professional differences between identified trajectories. Regression analyses were conducted to determine differences in patient outcomes. RESULTS: Three trajectories were identified as the following: 'stable high fidelity' (n = 9), 'moderate and improving fidelity' (n = 6), and 'unstable fidelity' (n = 2). The stable high fidelity organizations were generally smaller, started earlier, and implemented the program in a more structured way compared to moderate and improving fidelity organizations. At the implementation period's start and end, support from physicians and physiotherapists, professionals' appreciation, and program compatibility were rated more positively by professionals working in stable high fidelity organizations as compared to the moderate and improving fidelity organizations (p < .05). Qualitative data showed that the stable high fidelity organizations had often an explicit vision and strategy about the implementation of the program. Intriguingly, the trajectories were not associated with patients' self-reported physical activity outcomes (adjusted model beta = - 651.6, t(613) = - 1032, p = .303). CONCLUSIONS: Differences in organizational level implementation fidelity trajectories did not result in outcome differences at patient-level. This suggests that an effective implementation fidelity trajectory is contingent on the local organization's conditions. More specifically, achieving stable high implementation fidelity required the management of tensions: realizing a localized change vision, while safeguarding the program's standardized core components and engaging the scarce physicians throughout the process. When scaling up evidence-informed health promotion programs, we propose to tailor the management of implementation tensions to local organizations' starting position, size, and circumstances. TRIAL REGISTRATION: The Netherlands National Trial Register NTR3961 . Registered 18 April 2013. PMID- 29191232 TI - Active versus passive adverse event reporting after pediatric chiropractic manual therapy: study protocol for a cluster randomized controlled trial. AB - BACKGROUND: Patient safety performance can be assessed with several systems, including passive and active surveillance. Passive surveillance systems provide opportunity for health care personnel to confidentially and voluntarily report incidents, including adverse events, occurring in their work environment. Active surveillance systems systematically monitor patient encounters to seek detailed information about adverse events that occur in work environments; unlike passive surveillance, active surveillance allows for collection of both numerator (number of adverse events) and denominator (number of patients seen) data. Chiropractic manual therapy is commonly used in both adults and children, yet few studies have been done to evaluate the safety of chiropractic manual therapy for children. In an attempt to evaluate this, this study will compare adverse event reporting in passive versus active surveillance systems after chiropractic manual therapy in the pediatric population. METHODS/DESIGN: This cluster randomized controlled trial aims to enroll 70 physicians of chiropractic (unit of randomization) to either passive or active surveillance system to report adverse events that occur after treatment for 60 consecutive pediatric (13 years of age and younger) patient visits (unit of analysis). A modified enrollment process with a two-phase consent procedure will be implemented to maintain provider blinding and minimize dropouts. The first phase of consent is for the provider to confirm their interest in a trial investigating the safety of chiropractic manual therapy. The second phase ensures that they understand the specific requirements for the group to which they were randomized. Percentages, incidence estimates, and 95% confidence intervals will be used to describe the count of reported adverse events in each group. The primary outcome will be the number and quality of the adverse event reports in the active versus the passive surveillance group. With 80% power and 5% one-sided significance level, the sample size was calculated to be 35 providers in each group, which includes an 11% lost to follow-up of chiropractors and 20% of patient visits. DISCUSSION: This study will be the first direct comparison of adverse event reporting using passive versus active surveillance. It is also the largest prospective evaluation of adverse events reported after chiropractic manual therapy in children, identified as a major gap in the academic literature.

PMID- 29191233 TI - Functional dissection of Drosophila melanogaster SUUR protein influence on H3K27me3 profile. AB - BACKGROUND: In eukaryotes, heterochromatin replicates late in S phase of the cell cycle and contains specific covalent modifications of histones. SuUR mutation found in Drosophila makes heterochromatin replicate earlier than in wild type and reduces the level of repressive histone modifications. SUUR protein was shown to be associated with moving replication forks, apparently through the interaction with PCNA. The biological process underlying the effects of SUUR on replication and composition of heterochromatin remains unknown. RESULTS: Here we performed a functional dissection of SUUR protein effects on H3K27me3 level. Using hidden Markow model-based algorithm we revealed SuUR-sensitive chromosomal regions that demonstrated unusual characteristics: They do not contain Polycomb and require SUUR function to sustain H3K27me3 level. We tested the role of SUUR protein in the mechanisms that could affect H3K27me3 histone levels in these regions. We found that SUUR does not affect the initial H3K27me3 pattern formation in embryogenesis or Polycomb distribution in the chromosomes. We also ruled out the possible effect of SUUR on histone genes expression and its involvement in DSB repair. CONCLUSIONS: Obtained results support the idea that SUUR protein contributes to the heterochromatin maintenance during the chromosome replication. A model that explains major SUUR-associated phenotypes is proposed. PMID- 29191234 TI - Analysis of the relationship between prescribed dose and dosimetric advantage of real-time intraoperatively built custom-linked seeds in iodine-125 prostate brachytherapy. AB - BACKGROUND: The purpose of this study was to investigate the differences in the dosimetric advantage of using intraoperatively built custom-linked (IBCL) seeds between permanent iodine-125 (I-125) seed implantation (PI) alone and PI followed by external-beam radiation therapy (EBRT) for prostate cancer. METHODS: We reviewed the records of 62 patients with localized prostate cancer who received transperineal interstitial brachytherapy with I-125 using free seeds or IBCL seeds. Twenty-four low- and intermediate-risk patients underwent PI alone with the prescribed dose of 160 Gy, and 39 high-risk patients underwent PI with 110 Gy, followed by EBRT with 45 Gy (PI + EBRT). Intraoperative and post-implant dosimetric parameters 1 month after implantation were collected and analyzed. RESULTS: The numbers of patients implanted with free seeds and IBCL seeds were 14 (58.3%) and 10 (41.7%), respectively, in the PI group and 25 (65.8%) and 13 (34.2%), respectively, in the PI + EBRT group. In the PI group, although there were significant differences in prostate V100 (p = 0.003) and D90 (p = 0.009) and rectum V100 (p = 0.026) on intraoperative dosimetry, these differences were not found on post-implant dosimetry. In the PI + EBRT group, the dosimetric parameters of IBCL seeds, such as prostate V200 (p = 0.013) and V250 (p = 0.010) and urethra D30 (p = 0.038), were better than those of free seeds on intraoperative dosimetry. Furthermore, even on post-implant dosimetry, prostate D90 (p = 0.004), V150 (p = 0.001), and homogeneity index (HI, p = 0.001), as well as V200 (p = 0.001) and V250 (p = 0.020), and urethra D5 (p = 0.008) as well as D30 (p = 0.003) had a better dosimetric quality in IBCL seeds than in free seeds. There was no significant difference in the operation time between free seeds and IBCL seeds in each PI and PI + EBRT group. CONCLUSIONS: Our results reveal that greater dosimetric benefits could be obtained using IBCL seeds in the case of permanent implantation with a lower prescribed dose, such as PI + EBRT, rather than PI alone. PMID- 29191235 TI - Pediatric training and practice of Canadian chiropractic and naturopathic doctors: a 2004-2014 comparative study. AB - BACKGROUND: To assess chiropractic (DC) and naturopathic doctors' (ND) knowledge, attitudes, and behaviour with respect to the pediatric patients in their practice. METHODS: Cross-sectional surveys were developed in collaboration with DC and ND educators. Surveys were sent to randomly selected DCs and NDs in Ontario, Canada in 2004, and a national online survey was conducted in 2014. Data were analyzed using descriptive statistics, t-tests, non-parametric tests, and linear regression. RESULTS: Response rates for DCs were n = 172 (34%) in 2004, n = 553 (15.5%) in 2014, and for NDs, n = 171 (36%) in 2004, n = 162 (7%) in 2014. In 2014, 366 (78.4%) of DCs and 83 (61%) of NDs saw one or more pediatric patients per week. Pediatric training was rated as inadequate by most respondents in both 2004 and 2014, with most respondents (n = 643, 89.9%) seeking post graduate training by 2014. Respondents' comfort in treating children and youth is based on experience and post-graduate training. Both DCs and NDs that see children and youth in their practices address a broad array of pediatric health concerns, from well child care and preventative health, to mild and serious illness. CONCLUSIONS: Although the response rate in 2014 is low, the concerns identified a decade earlier remain. The majority of responding DCs and NDs see infants, children, and youth for a variety of health conditions and issues, but self-assess their undergraduate pediatric training as inadequate. We encourage augmented pediatric educational content be included as core curriculum for DCs and NDs and suggest collaboration with institutions/organizations with expertise in pediatric education to facilitate curriculum development, especially in areas that affect patient safety.

AB - BACKGROUND: A few methanogens have been previously recovered from periodontitis lesions, yet their repertoire may not be completed. We recovered a previously unreported methanogen species in this situation. CASE PRESENTATION: A 64-year-old Caucasian woman was diagnosed with chronic, severe generalized periodontitis. In the presence of negative controls, an 18-month culture of periodontal pockets in anaerobe Hungate tube yielded "Methanobrevibacter massiliense" and Pyramidobacter piscolens. CONCLUSIONS: This case report provides evidence of the symbiotic strategy deployed by the methanogens and the anaerobes, and reports the first culture of a new methanogen, "M. massiliense". PMID- 29191237 TI - The immediate effect of a soft knee brace on pain, activity limitations, self reported knee instability, and self-reported knee confidence in patients with knee osteoarthritis. AB - BACKGROUND: We aimed to (i) evaluate the immediate effect of a soft knee brace on pain, activity limitations, self-reported knee instability, and self-reported knee confidence, and (ii) to assess the difference in effect between a non-tight and a tight soft brace in patients with knee osteoarthritis (OA). METHODS: Forty four patients with knee OA and self-reported knee instability participated in the single-session, laboratory, experimental study. A within-subject design was used, comparing a soft brace with no brace, and comparing a non-tight with a tight soft brace. The outcome measures were pain, self-reported knee instability and knee confidence during level and perturbed walking on the treadmill and activity limitations (10-m walk test and the get up and go (GUG) test). Linear mixed effect model analysis for continuous outcomes and logistic generalized estimating equations for categorical outcomes were used to evaluate the effect of wearing a soft brace. RESULTS: Wearing a soft brace significantly reduced pain during level walking (B - 0.60, P = 0.001) and perturbed walking (B - 0.80, P < 0.001), reduced the time to complete the 10-m walk (B - 0.23, P < 0.001) and the GUG tests (B - 0.23, P = 0.004), reduced self-reported knee instability during level walking (OR 0.41, P = 0.002) and perturbed walking (OR 0.36, P < 0.001), and reduced lack of confidence in the knees during level walking (OR 0.45, P < 0.001) and perturbed walking (OR 0.56, P < 0.001), compared with not wearing a soft brace. There was no difference in effects between a non-tight and tight brace, except for the 10-m walk test. Wearing a tight brace significantly reduced the time to complete the 10-m walk test in comparison with wearing a non-tight brace (B - 0.11, P = 0.03). CONCLUSION: The results of this study indicate that a soft brace is an efficacious intervention targeting pain, activity limitations, self reported knee instability, and knee confidence in the immediate term in patients with knee OA. Further studies are needed evaluating the mode of action based on exerted pressure, and on the generalization to functioning in daily life. TRIAL REGISTRATION: trialregister.nl, NTR6363 . Retrospectively registered on 15 May 2017. PMID- 29191238 TI - Ethnopharmacological studies of indigenous plants in Kel village, Neelum Valley, Azad Kashmir, Pakistan. AB - BACKGROUND: This explorative study was undertaken for the first time in Kel village located in the Upper Neelum Valley, Azad Kashmir, Pakistan. The purpose was to document the indigenous knowledge of the native people used in the preparation of herbal medicines. METHODS: To get the data on traditional uses of medicinal plants, 20 informants were interviewed. Quantitative ethnobotanical indices, i.e., use value (UV), relative frequencies of citation (RFC), informant consensus factor (Fic), fidelity level (FL), data matrix ranking (DMR), preference ranking (PR), and jaccard index (JI), were calculated for the recorded medicinal plants. RESULTS: A total of 50 medicinal plants belonging to 33 families used in 13 disease categories were documented. Leaves were the frequently used plant parts, and decoction was the commonly used method for herbal medicine. Plants with high use value were Berberis lycium (2.05), Impatiens glandulifera (1.95), Artemisia scoparia (1.75), Ageratum conozoides (1.75), and Achillea millefolium (1.7). The highest RFC value was calculated for Berberis lycium (0.75), Cynoglossum lanceolatum (0.65), and Impatiens glandulifera and Achillea millefolium (0.60 each). The maximum informant consensus factor was for urinary system, cardiac diseases, baldness, and abortion and miscarriage (1.00). Berberis lyceum (95%) used in jaundice, hepatitis, typhoid, fever, and tuberculosis disorders. Plants with maximum fidelity level (FL) were Berberis lycium (95%) followed by Dioscorea bulbifera, Impatiens glandulifera, and Artemisia vulgaris (90%). Olea ferruginea was the most multipurpose plant and exports (21.2%) was the leading threat in the area. The pearson correlation coefficient (0.500) showed a positive correlation between the use value and relative frequency of citation. CONCLUSION: The present study provides useful information about traditional uses of medicinal plants used by local communities in different ailments. The plants with the highest use values could be employed in pharmacological research and biotechnological approaches in order to achieve adequate revenue. Some of the plants in the study area are facing high threats of becoming rare, and conservation initiatives are needed to conserve them for sustainable management in the region. PMID- 29191239 TI - Fine-scale population genetic structure of arctic foxes (Vulpes lagopus) in the High Arctic. AB - OBJECTIVE: The arctic fox (Vulpes lagopus) is a circumpolar species inhabiting all accessible Arctic tundra habitats. The species forms a panmictic population over areas connected by sea ice, but recently, kin clustering and population differentiation were detected even in regions where sea ice was present. The purpose of this study was to examine the genetic structure of a population in the High Arctic using a robust panel of highly polymorphic microsatellites. RESULTS: We analyzed the genotypes of 210 individuals from Bylot Island, Nunavut, Canada, using 15 microsatellite loci. No pattern of isolation-by-distance was detected, but a spatial principal component analysis (sPCA) revealed the presence of genetic subdivisions. Overall, the sPCA revealed two spatially distinct genetic clusters corresponding to the northern and southern parts of the study area, plus another subdivision within each of these two clusters. The north-south genetic differentiation partly matched the distribution of a snow goose colony, which could reflect a preference for settling into familiar ecological environments. Secondary clusters may result from higher-order social structures (neighbourhoods) that use landscape features to delimit their borders. The cryptic genetic subdivisions found in our population may highlight ecological processes deserving further investigations in arctic foxes at larger, regional spatial scales. PMID- 29191240 TI - Myopia as a risk factor for subsequent retinal tears in the course of a symptomatic posterior vitreous detachment. AB - BACKGROUND: Retinal tears complicating the course of a posterior vitreous detachment (PVD) may be unique or multiple, and when multiple they may occur simultaneously or subsequently at different moments in the evolution of a PVD. The purpose of our study was to analyze the prevalence of subsequent retinal tears (SRT) in patients with a PVD, and to identify possible risk factors for SRT. METHODS: One hundred and seventy six eyes in 165 consecutive patients that presented one or more retinal tears in the evolution of a symptomatic PVD, with a minimum follow-up of 12 months, were retrospectively evaluated. The primary outcome measure was to characterize the clinical features associated with SRT formation against those eyes with non-subsequent retinal tear (NSRT-retinal tear/s diagnosed at initial examination) formation. For that purpose, this cohort of patients was divided into two different groups: group 1 included eyes presenting one or multiple retinal tears only at initial examination (NSRT), and group 2 eyes that progressed to a further retinal tear/s (SRT) during follow-up. RESULTS: Group 1 comprised 154 eyes from 145 patients, 48.7% males and 51.3% females with a mean age of 56.9 +/- 14.0 years (range = 15-89); 17.2% of patients had a previous retinal tear or retinal detachment in the fellow eye; mean number of retinal tears per eye 1.42 +/- 0.8 (range = 1-5); 20.8% presented bilateral retinal tears; 59.1% were myopic eyes (p < 0.05). Group 2 comprised 22 eyes from 20 patients; mean age was 53.3 +/- 13.6 years (range = 30-69); 63.6% were male (p = 0.13), and 7 patients (31.8%) had a history of SRT or retinal detachment in the fellow eye (p = 0.13). The mean number of retinal tears per eye was 1.36 +/- 0.5 (range = 1-2); bilateral retinal tears were noted in 18.2% of eyes; 86.4% were myopic eyes (p = 0.01); 81.8% occurred within a 120 days-period following diagnosis of the first retinal tear. CONCLUSIONS: Multiple retinal tears may be diagnosed in the evolution of a PVD. SRT are most frequently observed in myopic patients, and are usually symptomatic. Follow-up must extend for at least 4 months after the initial symptoms. PMID- 29191241 TI - Preoperative detection of pleural adhesions by respiratory dynamic computed tomography. AB - BACKGROUND: Video-assisted thoracic surgery (VATS) plays an important role in thoracic surgery because it is less invasive. However, the existence of severe pleural adhesions may make VATS difficult and complicated. The aim of this study was to assess the utility of inspiration and expiration computed tomography (respiratory dynamic CT (RD-CT)) in evaluation of pleural adhesions preoperatively. METHODS: RD-CT was performed on 107 patients undergoing thoracotomies (both VATS and open). We assessed synchronous motion during respiration on RD-CT. Comparing the results of RD-CT and intraoperative findings, we assessed the utility of preoperative evaluation. RESULTS: A negative correlation between sliding score and adhesion grade was revealed. Sliding score in adhesion negative patients was significantly higher than that in adhesion positive patients (P < 0.0001). The sensitivity of RD-CT was 63.6%, specificity was 74.1%, and accuracy was 72%. Among 62 patients with a CT-Respiration Ratio of less than 0.65, the sensitivity of RD-CT was 77.8%, specificity was 86.8%, and accuracy was 85.5%. CONCLUSIONS: RD-CT may be clinically useful for detecting the presence of pleural adhesions. It can be adopted as one of the criteria for deciding the surgical approach. PMID- 29191243 TI - Potential for broad-scale transmission of Ebola virus disease during the West Africa crisis: lessons for the Global Health security agenda. AB - BACKGROUND: The 2014-2016 Ebola crisis in West Africa had approximately eight times as many reported deaths as the sum of all previous Ebola outbreaks. The outbreak magnitude and occurrence of multiple Ebola cases in at least seven countries beyond Liberia, Sierra Leone, and Guinea, hinted at the possibility of broad-scale transmission of Ebola. MAIN TEXT: Using a modeling tool developed by the US Centers for Disease Control and Prevention during the Ebola outbreak, we estimated the number of Ebola cases that might have occurred had the disease spread beyond the three countries in West Africa to cities in other countries at high risk for disease transmission (based on late 2014 air travel patterns). We estimated Ebola cases in three scenarios: a delayed response, a Liberia-like response, and a fast response scenario. Based on our estimates of the number of Ebola cases that could have occurred had Ebola spread to other countries beyond the West African foci, we emphasize the need for improved levels of preparedness and response to public health threats, which is the goal of the Global Health Security Agenda. Our estimates suggest that Ebola could have potentially spread widely beyond the West Africa foci, had local and international health workers and organizations not committed to a major response effort. Our results underscore the importance of rapid detection and initiation of an effective, organized response, and the challenges faced by countries with limited public health systems. Actionable lessons for strengthening local public health systems in countries at high risk of disease transmission include increasing health personnel, bolstering primary and critical healthcare facilities, developing public health infrastructure (e.g. laboratory capacity), and improving disease surveillance. With stronger local public health systems infectious disease outbreaks would still occur, but their rapid escalation would be considerably less likely, minimizing the impact of public health threats such as Ebola. CONCLUSIONS: The Ebola outbreak could have potentially spread to other countries, where limited public health surveillance and response capabilities may have resulted in additional foci. Health security requires robust local health systems that can rapidly detect and effectively respond to an infectious disease outbreak. PMID- 29191244 TI - Frequency, characteristics and risk factors of QT interval prolonging drugs and drug-drug interactions in cancer patients: a multicenter study. AB - BACKGROUND: Cancer patients may receive a high number of medications with the potential to prolong QT interval and subsequent TdP (torsades de pointes). This study aimed to identify the prevalence of QT prolonging drugs, their TdP risk, QT prolonging drug-drug interactions (QT-DDIs), levels, predictors, and TdP risk of drugs involved in QT-DDIs. METHODS: This multicenter study included cancer patients from three major tertiary care hospitals of Khyber-Pakhtunkhwa, Pakistan. Micromedex DrugReax(r) was used for identification of QT-DDIs. TdP risks were identified by AZCERT (Arizona Center for Education and Research on Therapeutics) classification. Logistic regression analysis was performed to identify predictors of QT-DDIs. RESULTS: Of 555 patients, 51% were females. Mean age was 46.9 +/- 15.7 years. Total 28 distinct QT prolonging drugs were identified in 92.6% of the patients. Overall 21.8% patients were presented with QT-DDIs. Of total 288 identified QT-DDIs, all were of major-severity and fair documentation. According to AZCERT classification, 59.9% of the interacting drugs were included in list-1 (known risk of TdP), 4.7% in list-2 (possible risk of TdP) and 6.8% in list-3 (conditional risk of TdP). Univariate logistic regression analysis showed significant results for various predictors such as, 8-9 prescribed medications (p < 0.001) and >=10 medications (p < 0.001), 2 QT drugs (p < 0.001) and >=3 QT drugs (p < 0.001), breast cancer (p = 0.03), gastrointestinal cancer (p = 0.03), 4-5 supportive care drugs (p < 0.001), 6-8 supportive care drugs (p < 0.001) and >8 supportive care drugs (p < 0.001). CONCLUSIONS: A high prevalence of QT prolonging drugs and QT-DDIs was reported in oncology. Appropriate precautions are needed to prevent harmful consequences of these interactions. PMID- 29191242 TI - Copy number variation meta-analysis reveals a novel duplication at 9p24 associated with multiple neurodevelopmental disorders. AB - BACKGROUND: Neurodevelopmental and neuropsychiatric disorders represent a wide spectrum of heterogeneous yet inter-related disease conditions. The overlapping clinical presentations of these diseases suggest a shared genetic etiology. We aim to identify shared structural variants spanning the spectrum of five neuropsychiatric disorders. METHODS: We investigated copy number variations (CNVs) in five cohorts, including schizophrenia (SCZ), bipolar disease (BD), autism spectrum disorders (ASD), attention deficit hyperactivity disorder (ADHD), and depression, from 7849 cases and 10,799 controls. CNVs were called based on intensity data from genome-wide SNP arrays and CNV frequency was compared between cases and controls in each disease cohort separately. Meta-analysis was performed via a gene-based approach. Quantitative PCR (qPCR) was employed to validate novel significant loci. RESULTS: In our meta-analysis, two genes containing CNVs with exonic overlap reached genome-wide significance threshold of meta P value < 9.4 * 10-6 for deletions and 7.5 * 10-6 for duplications. We observed significant overlap between risk CNV loci across cohorts. In addition, we identified novel significant associations of DOCK8/KANK1 duplications (meta P value = 7.5 * 10-7) across all cohorts, and further validated the CNV region with qPCR. CONCLUSIONS: In the first large scale meta-analysis of CNVs across multiple neurodevelopmental/psychiatric diseases, we uncovered novel significant associations of structural variants in the locus of DOCK8/KANK1 shared by five diseases, suggesting common etiology of these clinically distinct neurodevelopmental conditions. PMID- 29191245 TI - 3.0T MRI for long-term observation of lung nodules post cryoablation: a pilot study. AB - BACKGROUND: The purpose of this study was to use serial magnetic resonance imaging (MRI) examinations to observe changes in malignant lung tumors over time post-cryoablation. METHODS: The study protocol was approved by Institutional Review Board, and written informed consent was obtained from each participant in accordance with the Declaration of Helsinki. Patients with primary or metastatic lung tumors eligible for cryoablation were included in this prospective study. Cryoablation was performed according to standard procedures. Unenhanced and dynamic contrast-enhanced MRI scans were performed pre-cryoablation and at 1 day, 1 week, and 3-, 6-, and 12 months after cryoablation. At each time point, the signal intensity of the ablated zone on both T1WI and T2WI images, and volume and characteristics of the ablation zone were examined, and changes over time analyzed. RESULTS: A total of 26 nodules in 23 patients were included in the study. The mean patient age was 53.7 +/- 13.6 years, and 57.7% were males. Ablation zone volume increased to 1 week after the procedure, and then returned to baseline by 3 months. Cavitation post-cryoablation was found in 34.6% (9/26) of the nodules 1 month after treatment. Two types of time-signal intensity curves post-cryoablation were found: a straight line representing no definite enhancement from 1-day to 1-month, and an inflow curve representing mild delayed enhancement from month 3 to month 12. Local progression was associated with an incomplete hypointense rim around the ablation zone and absence of cavitation post-treatment. CONCLUSIONS: Characteristic changes are present on MRI after cryoablation of lung tumors. A complete hypointense rim and cavitation may be signs of adequate treatment and that local tumor progression is less likely. PMID- 29191247 TI - The implication of the shortage of health workforce specialist on universal health coverage in Kenya. AB - BACKGROUND: Globally, there is an acute shortage of human resources for health (HRH), and the greatest burden is borne by low-income countries especially in sub Saharan Africa and some parts of Asia. This shortage has not only considerably constrained the achievement of health-related development goals but also impeded accelerated progress towards universal health coverage (UHC). Like any other low income country, Kenya is experiencing health workforce shortage particularly in specialized healthcare workers to cater for the rapidly growing need for specialized health care (MOH Training Needs Assessment report (2015)). Efficient use of the existing health workforce including task shifting is under consideration as a short-term stop gap measure while deliberate efforts are being put on retention policies and increased production of HRH. METHODS: The Ministry of Health (MOH) with support from the United States Agency for International Development-funded FUNZOKenya project and MOH/Japan International Cooperation Agency (JICA) project conducted a country-wide training needs assessment (TNA) to identify skill gaps in the provision of specialized health care in private and public hospitals in 46 out of Kenya's 47 counties between April and June 2015. A total of 99 respondents participated in the TNA. Structured questionnaires were used to undertake this assessment. The assessment sought to determine the extent of skill gaps on the basis of the national guidelines and as perceived by the County Directors of Health (CDH). The questionnaires were posted to and received by all the respondents a week prior to a face-to-face interview with the respondents for familiarization. Data analysis was done using SPSS statistical package. RESULTS: Overall, the findings revealed average skill gaps on selected specialists (healthcare professional whose practice is limited to a particular area, such as a branch of medicine, surgery, or nursing, especially, one who by virtue of advanced training is certified by a specialty board as being qualified to so limit his or her practice, Free dictionary) at 85 and 62% when compared to the guideline and as perceived by the CDH respectively. It also revealed that gynecologists exceeded the requirements by 88 and 246% against the guidelines and as perceived by the CDH respectively. CONCLUSION: There is an overall huge gap in health specialists across the 46 counties, and the focus of training should be on the following specialists: cardio-surgeons, neurosurgeons, oncologists, nephrologists, lung and skin clinical officers, anesthetic clinical officers, cardiology nurses, forensic nurses, dental nurses, accident and emergency nurses, and oncology nurses. More innovative approaches, including the use of technology, need to be considered to address this challenge in the immediate, medium, and long terms. Policies and legal frameworks should be developed to facilitate cross county sharing of specialist expertise. Efforts need to be made to ensure harmonized skill gaps revealed by the guideline and as perceived by the CDHs to inform the development of mitigation strategies. PMID- 29191246 TI - MUNC18-1 gene abnormalities are involved in neurodevelopmental disorders through defective cortical architecture during brain development. AB - While Munc18-1 interacts with Syntaxin1 and controls the formation of soluble N ethylmaleimide-sensitive factor attachment protein receptors (SNARE) complex to regulate presynaptic vesicle fusion in developed neurons, this molecule is likely to be involved in brain development since its gene abnormalities cause early infantile epileptic encephalopathy with suppression-burst (Ohtahara syndrome), neonatal epileptic encephalopathy and other neurodevelopmental disorders. We thus analyzed physiological significance of Munc18-1 during cortical development. Munc18-1-knockdown impaired cortical neuron positioning during mouse corticogenesis. Time-lapse imaging revealed that the mispositioning was attributable to defects in radial migration in the intermediate zone and cortical plate. Notably, Syntaxin1A was critical for radial migration downstream of Munc18 1. As for the underlying mechanism, Munc18-1-knockdown in cortical neurons hampered post-Golgi vesicle trafficking and subsequent vesicle fusion at the plasma membrane in vivo and in vitro, respectively. Notably, Syntaxin1A-silencing did not affect the post-Golgi vesicle trafficking. Taken together, Munc18-1 was suggested to regulate radial migration by modulating not only vesicle fusion at the plasma membrane to distribute various proteins on the cell surface for interaction with radial fibers, but also preceding vesicle transport from Golgi to the plasma membrane. Although knockdown experiments suggested that Syntaxin1A does not participate in the vesicle trafficking, it was supposed to regulate subsequent vesicle fusion under the control of Munc18-1. These observations may shed light on the mechanism governing radial migration of cortical neurons. Disruption of Munc18-1 function may result in the abnormal corticogenesis, leading to neurodevelopmental disorders with MUNC18-1 gene abnormalities. PMID- 29191248 TI - Squamous cell carcinoma arising from a keratocystic odontogenic tumor: a case report. AB - BACKGROUND: The term "primary intraosseous squamous cell carcinoma" was introduced in 2005 by the World Health Organization with three subcategories. Squamous cell carcinoma arising from the lining of an odontogenic cyst is one important rare subcategory of such lesions with an incidence of 0.01 to 0.02%. Furthermore, the appearance of such malignancy in an odontogenic tumor such as keratocystic odontogenic tumor is considered extremely rare. CASE PRESENTATION: In this case report we report a case of a 50-year-old Sri Lankan woman who complained of pain and increase in the size of a swelling at the anterior mandible, which had been present for over 1 year. The increase was significant for 1 month with accompanying numbness of the left half of her lip. Cone beam computed tomography results revealed an irregular radiolucent lesion involving most of her mandible and, except in the anterior part, very little buccolingual expansion was seen that suggested a keratocystic odontogenic tumor. An excision biopsy of the cyst lining confirmed a squamous cell carcinoma arising from a preexisting keratocystic odontogenic tumor. CONCLUSIONS: Even though primary intraosseous squamous cell carcinoma arising from a keratocystic odontogenic tumor is considered to be very rare, the present case is comparable to most of the aspects cited in the literature. The current case emphasizes the importance of careful investigation of swellings present in the mandible. Clinicians as well as patients should be aware and detect these changes to avoid being clinically negligent. PMID- 29191249 TI - Tracing GFP-labeled WJMSCs in vivo using a chronic salpingitis model: an animal experiment. AB - BACKGROUND: The present study was conducted to evaluate the distribution of Wharton's jelly-derived mesenchymal stem cells (WJMSCs) and their repairing function on the oviduct. METHODS: WJMSCs were transfected with the LV3-GFP-PURO lentivirus. Female New Zealand rabbits (n = 24) were divided randomly into control A and B groups and experimental C and D groups to establish inflammation models. Sterile saline solution or WJMSCs were injected into rabbits via ear veins and/or genital tract perfusion once weekly for 3 weeks. All rabbits were humanely sacrificed 1 week after the last perfusion to collect the oviduct, uterus, liver, and bladder for examination. Green fluorescent protein (GFP) and cytokeratin 7 (CK7) were imaged using a Leica Qwin Plus V3 fluorescence confocal microscope and analyzed as mean optical densities in an Image-Pro Plus analysis system. RESULTS: We found that lentivirus expressing the GFP gene produced an efficient transfection. The mean optical density values of GFP and CK7 in the oviducts were higher in the experimental D group than those in the control A and experimental C groups. No GFP fluorescence deposits occurred in the bladder of the control A group or experimental C group. Colocalization of CK7 and WJMSCs was observed in the oviducts in all groups. CONCLUSIONS: WJMSCs exhibited homing characteristics and migrated to the injured oviduct to promote epithelial cell growth. Additionally, local treatment resulted in higher efficiency. PMID- 29191250 TI - Sociodemographic factors are associated with dietary patterns in Mexican schoolchildren. AB - OBJECTIVE: Childhood obesity has increased rapidly in Mexico, along with changes in the food environment. However, little is known about the dietary patterns (DP) of Mexican children. We aimed to characterize the DP of schoolchildren and to analyse their associations with sociodemographic factors. DESIGN: Cross-sectional analysis. Dietary and sociodemographic information was obtained, including a single 24 h recall, socio-economic status (SES), geographic region, area of residence and ethnicity. DP were defined with cluster analysis (using k-means). Multinomial logistic regression models, adjusted for the survey design, were used to assess associations between DP and sociodemographic variables. SETTING: 2012 Mexican National Health and Nutrition Survey (ENSANUT-2012). SUBJECTS: Schoolchildren (n 2751) aged 5-11 years who participated in ENSANUT-2012. RESULTS: Four DP were identified: 'Traditional', 'Industrialized', 'Varied' and 'Modern'. Reported energy intake (mean (sd)) was lowest in the 'Traditional' and highest in the 'Industrialized' DP (7037 (3707) kJ/d (1682 (886) kcal/d) v. 8427 (3753) kJ/d (2014 (897) kcal/d), respectively, P<0.05). Significant differences in fat and fibre intakes were seen across DP. Non-indigenous v. indigenous children were 22.0 times (95 % CI 5.1, 93.6) more likely to have a 'Modern' rather than 'Traditional' DP. Relative likelihood of having an 'Industrialized' rather than 'Traditional' DP was 6.2 (95 % CI 3.9, 9.9) among schoolchildren from high SES v. low SES. CONCLUSIONS: Among Mexican schoolchildren, DP were associated with sociodemographic variables. Non-indigenous children were significantly more likely to consume a 'Modern' than a 'Traditional' DP. Children with higher SES were more likely to have an 'Industrialized' pattern. It is necessary to consider dietary characteristics in the different sociodemographic strata when dietary interventions are designed. PMID- 29191251 TI - Grooves surrounding the micropyle decrease the inseminating dose in fish. AB - In fish with external fertilization, sperm must reach the oocyte through the micropyle to enter the cytoplasm. Fertilization success is then influenced by characteristics of oocytes or sperm. In this study, we evaluated oocyte morphology and sperm motility parameters and their effects on the inseminating dose in a teleost fish Astyanax altiparanae. Interestingly, we found one of the lowest yet described inseminating doses in teleosts (2390 spermatozoa oocyte-1 ml 1). Such a fertilization efficacy may be explained by the long duration of sperm motility (>75 s), the small oocyte diameter (695.119 um), large micropyle diameter (7.57 um), and the presence of grooves on the oocyte surface that guides spermatozoon to the fertilization area. Additionally, we have described for the first time a structure that combines grooves on the chorion surface and a ridge in the micropylar area. PMID- 29191252 TI - Pseudopregnancy and aseasonal breeding in dairy goats: genetic basis of fertility and impact on lifetime productivity. AB - Until recently, the main selection focus in UK dairy goats has been on milk yield. To develop a selection index suitably weighted for a variety of traits, it is important to understand the genetic relationships between production, health and fertility traits. This study focussed on three aspects of reproduction that are of interest to goat breeders. (1) Out of season (OOS) kidding ability: goats are highly seasonal breeders so achieving consistent, year-round dairy production presents a challenge. It may be possible to select for extended or shifted breeding cycles, however, there are no published studies on the genetic basis of seasonal kidding ability, and a genetic correlation with milk production in dairy goats; (2) age at first kidding (AFK): a reduced AFK offers the opportunity for more rapid genetic improvement, as well as reducing the amount of time and resources required to raise the animals to producing age; (3) pseudopregnancy (PPG): as it is difficult to diagnose pregnancy within 30 days of mating, high herd levels of PPG could add a significant delay in breeding replacement animals, or commencing a new lactation. Using records from 9546 goats, the objective of this study was to investigate the genetic relationships between the reproductive traits described above, and the production traits 520-day milk yield (MY520), lifetime milk yield (MYLife) and lifetime number of days in milk (DIMLife). The 'out of season' phenotype was defined as week of kidding relative to the 4 weeks of the year where the highest average number of births occur. Incidences of PPG that occurred during the first lactation were used as cases, while goats with none were assigned as controls. Relevant fixed and random effects were fitted in the models. In line with other reproduction traits, heritability estimates were low ranging from 0.08 to 0.11. A negative genetic correlation was found between AFK and MY520 (-0.22+/-0.10), whereas a positive genetic correlation was found between PPG and DIMLife (0.58+/-0.11). Pseudopregnancy and OOS were positively genetically correlated (0.36+/-0.15). All other genetic correlations were very low. The results of this study indicate that selection for the reproductive traits analysed is feasible, without adversely affecting MYLife.

PMID- 29191255 TI - Resveratrol and inflammatory bowel disease: the evidence so far. AB - Despite the fact that inflammatory bowel disease (IBD) has still no recognised therapy, treatments which have proven at least mildly successful in improving IBD symptoms include anti-inflammatory drugs and monoclonal antibodies targeting pro inflammatory cytokines. Resveratrol, a natural (poly)phenol found in grapes, red wine, grape juice and several species of berries, has been shown to prevent and ameliorate intestinal inflammation. Here, we discuss the role of resveratrol in the improvement of inflammatory disorders involving the intestinal mucosa. The present review covers three specific aspects of resveratrol in the framework of inflammation: (i) its content in food; (ii) its intestinal absorption and metabolism; and (iii) its anti-inflammatory effects in the intestinal mucosa in vitro and in the very few in vivo studies present to date. Actually, if several studies have shown that resveratrol may down-regulate mediators of intestinal immunity in rodent models, only two groups have performed intervention studies in human subjects using resveratrol as an agent to improve IBD conditions. The effects of resveratrol should be further investigated by conducting well-designed clinical trials, also taking into account different formulations for the delivery of the bioactive compound.

AB - The apicomplexan protozoan parasites include the causative agents of animal and human diseases ranging from malaria (Plasmodium spp.) to toxoplasmosis (Toxoplasma gondii). The complex life cycle of T. gondii is regulated by a unique family of calcium-dependent protein kinases (CDPKs) that have become the target of intensive efforts to develop new therapeutics. In this review, we will summarize structure-based strategies, recent successes and future directions in the pursuit of specific and selective inhibitors of T. gondii CDPK1.

AB - The U.S. Department of Agriculture, Food Safety Inspection Service regulatory method for monensin, Chemistry Laboratory Guidebook CLG-MON, is a semiquantitative bioautographic method adopted in 1991. Official Method of AnalysisSM (OMA) 2011.24, a modern quantitative and confirmatory LC-tandem MS method, uses no chlorinated solvents and has several advantages, including ease of use, ready availability of reagents and materials, shorter run-time, and higher throughput than CLG-MON. Therefore, a bridging study was conducted to support the replacement of method CLG-MON with OMA 2011.24 for regulatory use. Using fortified bovine tissue samples, CLG-MON yielded accuracies of 80-120% in 44 of the 56 samples tested (one sample had no result, six samples had accuracies of >120%, and five samples had accuracies of 40-160%), but the semiquantitative nature of CLG-MON prevented assessment of precision, whereas OMA 2011.24 had accuracies of 88-110% and RSDr of 0.00-15.6%. Incurred residue results corroborated these results, demonstrating improved accuracy (83.3-114%) and good precision (RSDr of 2.6-20.5%) for OMA 2011.24 compared with CLG-MON (accuracy generally within 80-150%, with exceptions). Furthermore, chi2 analysis revealed no statistically significant difference between the two methods. Thus, the microbiological activity of monensin correlated with the determination of monensin A in bovine tissues, and OMA 2011.24 provided improved accuracy and precision over CLG-MON. PMID- 29191257 TI - Proteasome Inhibitor MG132 Enhances Cisplatin-Induced Apoptosis in Osteosarcoma Cells and Inhibits Tumor Growth. AB - Although cisplatin has been shown to be an integral part of chemotherapy regimen in osteosarcoma (OS) treatment, toxicity issues and chemoresistance have hindered therapeutic development for OS. Exploring novel combination therapy methods is needed to circumvent the limitations of cisplatin alone. The proteasome inhibitor MG132 has shown antitumor effects in many solid tumors. However, little is known about its effects in combination with cisplatin in OS cells. In this study, we examined the effects of MG132 in combination with cisplatin in human OS cells (MG 63 and HOS). MG132 and cisplatin were applied to OS cells, respectively or jointly. The results demonstrated that MG132 markedly inhibited cell viability in a dose- and time-dependent manner, whereas viability of osteoblast cells was not affected, suggesting a selective toxicity of MG132 to cancerous cells. Mechanistically, MG132 arrested cells in the G2/M phase in association with increased p21waf1 and induced cell apoptosis, which was accompanied by cleaved PARP. In addition to its apoptotic effect alone, MG132 significantly enhanced cisplatin-induced apoptosis in OS cells. Furthermore, cell viability of the combined application of 10 MUM MG132 and 5 MUg/ml cisplatin was markedly inhibited compared to that of the individual application. These events were accompanied by the downregulation of NF-kappaB, mitochondrial antiapoptotic protein Bcl-xL, and PI3K/Akt, which play a key role in cell survival. Finally, combination treatment of MG132 and cisplatin showed more antiproliferative effect than the single treatment in OS xenograft models. In summary, we concluded that MG132 interacted synergistically with cisplatin, which raised the possibility that combining the two drugs may represent a novel strategy in OS.

AB - BACKGROUND: Cumulative exposure to ultraviolet radiation (UV) is a risk factor for development of skin cancer. We estimated changes in knowledge, attitudes, and behaviors among Nevada school-age children following implementation of a program to decrease UV exposure. COMMUNITY CONTEXT: The Nevada Cancer Coalition's Sun Smart Schools pilot program was implemented in 7 Nevada schools during the 2015 2016 school year. The target population was students at participating schools. METHODS: Participation in the program was voluntary. Students surveyed spanned grades from fourth to tenth. Pre-intervention surveys were conducted at the start of the school year. Post-intervention surveys were conducted at the end of the school year. Changes in knowledge, attitudes, and behaviors were assessed among study participants by using self-reported survey responses. OUTCOMES: The Sun Smart Schools pilot program was effective in increasing a broad range of knowledge, attitudes, and behaviors about protection from UV among elementary and middle school students. Students in high school reported an increase in the adoption of selected protective behaviors. However, this population also maintained a positive attitude toward the appearance of tanned skin, indicating susceptibility to competing influences. High school students also did not report any evident change in knowledge about sun protection strategies. Parents reported a decrease in knowledge about UV protection but an increase in adoption of certain protective behaviors. INTERPRETATION: Our findings are similar to those of previous studies demonstrating that education about the dangers of UV exposure is most effective in younger age groups. Results were mixed in older age groups. PMID- 29191259 TI - Exposure to Advertisements and Marijuana Use Among US Adolescents. AB - INTRODUCTION: This study examined whether exposure to marijuana advertisements was associated with current marijuana use and frequency of use among US adolescents in grades 8, 10, and 12. METHODS: Weighted estimates of exposure to marijuana advertisements and marijuana use from the 2014 and 2015 Monitoring the Future studies were investigated. Factors associated with the prevalence and frequency of marijuana use were analyzed by using logistic regression and linear regression models, respectively. RESULTS: Of all respondents (n = 12,988), 13.8% reported marijuana use in the past 30 days. Exposure to marijuana advertisements was prevalent among adolescents, with 52.8% reporting exposure from internet advertisements, 32.1% from television advertisements, 24.1% from magazine or newspaper advertisements, 19.7% from radio advertisements, 19.0% from advertisements on storefronts, and 16.6% from billboards. In the multivariable analysis, current use of marijuana among adolescents was associated with exposure to marijuana advertisements on storefronts (adjusted odds ratio [OR] = 1.4, P < .001), magazines or newspapers (adjusted OR = 1.6, P < .001), billboards (adjusted OR = 1.4, P = .002), internet (adjusted OR = 1.8, P < .001), television (adjusted OR = 1.4, P < .001) and radio (adjusted OR = 1.7, P < .001). Exposure to marijuana advertisements from the internet was associated with increased use of marijuana (beta = 0.3, P = .04). CONCLUSION: Exposure to marijuana advertisements was associated with higher odds of current marijuana use among adolescents. Regulations that limit marijuana advertisements to adolescents and educational campaigns on harmfulness of illicit marijuana use are needed. PMID- 29191260 TI - Physical Activity as a Vital Sign: A Systematic Review. AB - INTRODUCTION: Physical activity (PA) is strongly endorsed for managing chronic conditions, and a vital sign tool (indicator of general physical condition) could alert providers of inadequate PA to prompt counseling or referral. This systematic review examined the use, definitions, psychometric properties, and outcomes of brief PA instruments as vital sign measures, with attention primarily to studies focused on arthritis. METHODS: Electronic databases were searched for English-language literature from 1985 through 2016 using the terms PA, exercise, vital sign, exercise referral scheme, and exercise counseling. Of the 838 articles identified for title and abstract review, 9 articles qualified for full text review and data extraction. RESULTS: Five brief PA measures were identified: Exercise Vital Sign (EVS), Physical Activity Vital Sign (PAVS), Speedy Nutrition and Physical Activity Assessment (SNAP), General Practice Physical Activity Questionnaire (GPPAQ), and Stanford Brief Activity Survey (SBAS). Studies focusing on arthritis were not found. Over 1.5 years of using EVS in a large hospital system, improvements occurred in relative weight loss among overweight patients and reduction in glycosylated hemoglobin among diabetic patients. On PAVS, moderate physical activity of 5 or more days per week versus fewer than 5 days per week was associated with a lower body mass index (-2.90 kg/m2). Compared with accelerometer-defined physical activity, EVS was weakly correlated (r = 0.27), had low sensitivity (27%-59%), and high specificity (74%-89%); SNAP showed weak agreement (kappa = 0.12); GPPAQ had moderate sensitivity (46%) and specificity (50%), and SBAS was weakly correlated (r = 0.10-0.28), had poor to moderate sensitivity (18%-67%), and had moderate specificity (58%-79%). CONCLUSION: Few studies have examined a brief physical activity tool as a vital sign measure. Initial investigations suggest the promise of these simple and quick assessment tools, and research is needed to test the effects of their use on chronic disease outcomes. PMID- 29191261 TI - Do Cancer-Related Fatigue and Physical Activity Vary by Age for Black Women With a History of Breast Cancer? AB - INTRODUCTION: Cancer-related fatigue (CRF) is the most uncomfortable symptom among women with a history of breast cancer. Black women are more likely than women of other racial/ethnic groups to have CRF risk factors, such as physical inactivity and obesity, yet CRF studies have not focused on black women. We conducted a cross-sectional analysis to assess CRF and physical activity among black women survivors of breast cancer. METHOD: In May and July of 2012, 267 members (mean age, 54 y) of the Sisters Network, Inc, completed an online survey of sociodemographic characteristics, medical characteristics, and physical activity, and a fatigue instrument (the Functional Assessment of Chronic Illness Therapy [FACIT]). Multiple linear regression assessed fatigue and physical activity compliance (ie, 150 minutes of moderate to vigorous physical activity per week). RESULTS: Participants had an average FACIT score of 32.3, Fatigue was greater (P < .001) among the 56% of women not meeting physical activity guidelines. In multivariable analysis, correlates of fatigue showed that physical activity compliance (beta = 3.20, P < .001) and older age group (50-59 y: beta = 3.98, P = .001; >=60 y,: beta = 3.76, P = .003) were associated with less fatigue. The interaction between age and fatigue was also significant: mean differences in fatigue by physical activity level were obvious only among women younger than 50 years. (P < .001). CONCLUSION: Physical activity compliance was associated with a lower level of fatigue. However, the effect of physical activity on fatigue may differ by age. Interventions aimed at curbing CRF in black women should consider age-appropriate strategies that can be integrated into existing lifestyles.

AB - INTRODUCTION: Although practitioners in state health departments are ideally positioned to implement evidence-based interventions, few studies have examined how to build their capacity to do so. The objective of this study was to explore how to increase the use of evidence-based decision-making processes at both the individual and organization levels. METHODS: We conducted a 2-arm, group randomized trial with baseline data collection and follow-up at 18 to 24 months. Twelve state health departments were paired and randomly assigned to intervention or control condition. In the 6 intervention states, a multiday training on evidence-based decision making was conducted from March 2014 through March 2015 along with a set of supplemental capacity-building activities. Individual-level outcomes were evidence-based decision making skills of public health practitioners; organization-level outcomes were access to research evidence and participatory decision making. Mixed analysis of covariance models was used to evaluate the intervention effect by accounting for the cluster randomized trial design. Analysis was performed from March through May 2017. RESULTS: Participation 18 to 24 months after initial training was 73.5%. In mixed models adjusted for participant and state characteristics, the intervention group improved significantly in the overall skill gap (P = .01) and in 6 skill areas. Among the 4 organizational variables, only access to evidence and skilled staff showed an intervention effect (P = .04). CONCLUSION: Tailored and active strategies are needed to build capacity at the individual and organization levels for evidence-based decision making. Our study suggests several dissemination interventions for consideration by leaders seeking to improve public health practice. PMID- 29191263 TI - Persistent and severe hypoglycemia associated with trimethoprim-sulfamethoxazole in a frail diabetic man on polypharmacy: A case report and literature review?. AB - OBJECTIVE: Trimethoprim-sulfamethoxazole (co-trimoxazole) is a commonly used broad-spectrum antibiotic, but it can be associated with potentially serious adverse effects, often not recognized by clinicians. This is a relevant problem in elderly patients, who are particularly susceptible to adverse drug reactions. Moreover, multiple medications taken by older people increase the risk for adverse drug reactions and drug-drug interactions. CASE REPORT: We report the case of an 85-year-old man with diabetes mellitus who attended the emergency room with severe hypoglycemia that persisted despite multiple intravenous bolus doses and continuous infusion of glucose. He needed hospital admission to stabilize glycemia. The patient, a nursing home resident, was being treated with co trimoxazole for an uncomplicated urinary tract infection, but was also taking multiple additional drugs for his co-morbidities. After co-trimoxazole was discontinued, plasma glucose levels slowly stabilized within the normal range. A diagnosis of prolonged and refractory hypoglycemia induced mainly by the antimicrobial agent was made, with additional contribution from multiple other drugs. No further episodes of hypoglycemia occurred during the next 6 months of follow-up. CONCLUSION: This case study illustrates once more the critical importance of prescription appropriateness in elderly patients with multiple morbidities in terms of type and dosage of drugs, in order to avoid serious adverse reactions.?.

Eur.) general chapter 5.14. Gene transfer medicinal products for human use suggests the use of absorbance measurements at 260 nm to determine the DNA concentration of plasmid vectors used for the preparation of gene therapy products for human use. An international collaborative study was organised by the European Directorate for the Quality of Medicines & HealthCare (EDQM) to confirm the suitability of UV spectrophotometry for the quantification of plasmid vectors used in gene therapy (GT). Three Official Medicine Control Laboratories (OMCLs of the European OMCL Network) and members of the OMCL Working Group for GT products took part in the study, in which various types of spectrophotometers were assessed using common test samples. Results of the study demonstrated that UV spectrophotometry can be considered suitable for the quantification of plasmid DNA in GT products regardless of the instrument used.

Aside from plummeting health care costs, we might enjoy a healthier life free of cancer and chronic disease. Prevention requires the adoption of healthier choices and a moderate amount of exercise. The supporting evidence is observational, clinical, and partly common sense. Further investigations reveal several substances in a whole-food plant-based diet that have protective effects and an inhibitory effect on tumor development. For pancreatic cancer, the basis of cure remains a century old operation that rarely cures. With little to lose, prevention deserves center stage and additional studies.

This article reviews the trials of pancreatic cancer and radiation in adjuvant, neoadjuvant, and unresectable lesions. The article reviews the impact and outcomes of evolving radiation technology. PMID- 29191269 TI - Nonoperative Ablation of Pancreatic Neoplasms. AB - Pancreatic cancer is a poor prognostic tumor and about 20% of patients are eligible for surgical resection at the time of diagnosis. Recently, minimally invasive procedures have provided promising results as a therapeutic option for locally advanced unresectable pancreatic cancer. In particular, high-intensity focused ultrasound is an emerging noninvasive thermally ablative procedure that may have a dominant role in the future. Although the clinical applications of minimally invasive therapies to pancreatic cancers are still in their infancy, the results at present are promising. PMID- 29191270 TI - Preoperative Evaluation of a Pancreas Mass: Diagnostic Options. AB - As modern abdominal imaging equipment advances, pancreatic lesion detection improves. Most of these lesions are incidental, and present a conundrum to the clinician and create great anxiety to the patient until a final diagnosis is made. For the practicing physician, the plethora of diagnostic options is overwhelming. The relevant question is, what is the most efficient algorithm to follow and to arrive at a timely and accurate diagnosis. This article presents a logical approach to the initial evaluation of a pancreatic lesion to get the most information possible with the least amount of testing, and to avoid duplicative measures. PMID- 29191271 TI - Incidental Intraductal Papillary Mucinous Neoplasm, Cystic or Premalignant Lesions of the Pancreas: The Case for Aggressive Management. AB - Incidental cystic intrapancreatic lesions are daily findings in abdominal radiology. The discovery of incidental pancreatic lesions is increasingly common with technologic diagnostic advancements. This article provides a perspective and guideline on the clinical management of incidental intraductal papillary mucinous neoplasms and cystic or premalignant lesions of the pancreas. PMID- 29191272 TI - Nonfunctioning Incidental Pancreatic Neuroendocrine Tumors: Who, When, and How to Treat? AB - Asymptomatic non-functioning pancreatic neuroendocrine tumors are indolent, slow growing tumors, and surveillance is safe and reasonable. Despite consensus, size may be less important than grade and Ki-67 when making decisions regarding optimal therapy. Plans to proceed with surveillance or surgical resection require a multidisciplinary approach and a shared decision making process with colleagues, patients, and families. Decisions should be based on tumor characteristics, patient morbidities, preferences, and risks. As molecular diagnostics evolve, preoperative acquisition of tissue samples may become even more critical in choosing between operative management and surveillance. PMID- 29191273 TI - Rare Tumors and Lesions of the Pancreas. AB - There are a few entities that account for most solid and cystic masses of the pancreas. The pancreas harbors a wide array of diseases, including adenocarcinoma, and its variants, such as anaplastic and adenosquamous carcinoma. Other neoplasms include acinar cell carcinoma, solid pseudopapillary tumor, and sarcomas. Benign lesions include hamartomas, hemangiomas, lymphangioma, and plasmacytoma. Isolated metastases include renal cell carcinoma, melanoma, and other carcinomas. Benign inflammatory conditions, such as autoimmune pancreatitis and groove pancreatitis can also mimic solid neoplasms of the pancreas. PMID- 29191274 TI - Ex Vivo Resection and Autotransplantation for Pancreatic Neoplasms. AB - There are several low-grade pancreatic tumors whose biology permits the use of aggressive surgery to achieve a curative resection. Tumors that are deemed unresectable by conventional techniques due to mesenteric vessel involvement may benefit from ex vivo tumor resection and autotransplantation to allow complete resection while minimizing ischemic organ injury. Despite the excellent oncologic outcomes when used for these neoplasms, the procedure carries substantial morbidity and a high complication rate. But for patients who were otherwise offered total enterectomy and allotransplantation or told that their tumor was unresectable, ex vivo resection may offer them a hope for cure. PMID- 29191275 TI - Screening of Patients at Risk for Familial Pancreatic Cancer: What Is Beneficial? AB - Family history is a significant risk factor for developing pancreatic cancer and this hereditary risk can be secondary to familial cancer predisposition syndromes, hereditary pancreatitis, or familial pancreatic cancer. Certain high risk individuals are recommended to undergo screening for pancreatic cancer with endoscopic ultrasound or MRI/magnetic resonance retrograde cholangiopancreatography because of the potential to identify and curatively resect precursor lesions. The management of suspicious lesions identified on screening high-risk individuals is also discussed. PMID- 29191276 TI - Preoperative Stenting for Benign and Malignant Periampullary Diseases: Unnecessary if Not Harmful. AB - Preoperative biliary drainage (PBD) is often performed in patients with jaundice with the presumption that it will decrease the risk of postoperative complications. PBD carries its own risk of complications and, therefore, has been controversial. Multiple randomized controlled trials and metaanalyses have shown that PBD has significantly increased overall complications compared with surgery alone. As such, the routine application of PBD should be avoided except in a subset of clinical situations. This is discussed in detail in this article. PMID- 29191277 TI - A Tale of 2 Techniques: Preoperative Biliary Drainage and Routine Surgical Drainage with Pancreaticoduodenectomy. AB - Preoperative drainage of an obstructed biliary tree before pancreaticoduodenal resection (PDR) and placement of intraabdominal drains following pancreatic resection have been suggested to be both unnecessary and associated with a higher complication rate. The evidence for and against that practice is presented and analyzed to highlight its risks and benefits. A selective approach on an individual basis for preoperative biliary decompression is advocated, based on multiple factors. Additionally, the evidence for routine use of surgical drains after PDR is critically reviewed and the rationale for routine drainage is made. PMID- 29191278 TI - Timing of Pancreatic Resection and Patient Outcomes: Is There a Difference? AB - Rates of long-term survival after treatment of pancreatic cancer remain low, in part because most patients are still treated with primary resection. This approach is often inadequate because of early local control failures, early manifestation of metastatic disease because of the unrecognized and untreated systemic component of this disease, and because half of patients never receive multimodal therapy. Preoperative therapy can be used to improve local control and treat the systemic nature of pancreatic cancer while also selecting for patients who benefit from a morbid operation. Preoperative therapy makes sense for most patients with this aggressive and deadly disease. PMID- 29191279 TI - Cancer of the Pancreas-Actual 5, 10, and 20+Year Survival: The Lucky and Fortunate Few. AB - Cancer of the pancreas (CaP) is a dismal, uncommon, systemic malignancy.

Survival is expressed as actual, not projected, survival. PMID- 29191280 TI - Rare, Uncommon, and Unusual Complications After Pancreaticoduodenal Resection. AB - Complications after pancreaticoduodenal resection occur in at least 30% of patients. Most are a direct result of an intraoperative event, dissection, or anastomoses which account for the most serious morbidities, sepsis, pseudoaneurysms, and hemorrhage. Rarely, complications are due to the systemic impact of the procedure even if the procedure itself was unremarkable. Rare systemic complications after PDR (Transfusion transmitted Babesiosis, pituitary apoplexy, and TRALI) and a number of uncommon and unusual other complications are discussed. Pancreaticoduodenal resection is a significant operation with serious consequences. Decisions on selection of candidates and safe operations should be thoughtful and always in surgeons' minds. PMID- 29191281 TI - Adjuvant or Neoadjuvant Therapy in the Treatment in Pancreatic Malignancies: Where Are We? AB - Since the advent of modern surgery for pancreatic cancer, clinicians have recognized this cancer's propensity to recur locally, metastasize, and cause death. Despite significant efforts to improve patient outcomes with better adjuvant therapy, only modest gains in survival have been observed. An alternative strategy of neoadjuvant therapy followed by surgery has the potential to improve patient selection and survival, and expand the pool of patients eligible for curative surgery. This article summarizes large, randomized trials of adjuvant therapy, explains the limitations imposed by up-front surgery, and suggests neoadjuvant therapy as a rational alternative to initial surgery and adjuvant therapy.

PMID- 29191285 TI - Effects of 3 Different Elastic Therapeutic Taping Methods on the Subacromial Joint Space. AB - OBJECTIVE: The purpose of this study was to examine the effects of 3 different elastic therapeutic taping methods on the subacromial joint space in healthy adults. METHODS: Pre-/post-test laboratory study method was used in this study. Forty-eight healthy adults with no prior history of shoulder injury or surgery and no history of dominant shoulder pain in the past 6 months were enrolled in the study. Participants were placed into 3 groups (8 males and 8 females per group) on the basis of a consecutively assigned allocation design. A baseline measurement of the acromiohumeral distance (AHD) was taken by using diagnostic ultrasonography for every participant. On the basis of group assignment, participants were then taped according to the Kinesio Tape (Kinesio Tex Classic Tape) guidelines in one of 3 conditions: (1) taping of the supraspinatus from insertion to origin; (2) taping of the anterior and posterior deltoids from insertion to origin; and (3) a combination of both techniques. After a 5-minute wait period, the AHD was remeasured with the tape intervention in place, with each participant serving as his or her own control. RESULTS: Data analysis showed a statistically significant increase in AHD when using the taping technique over the anterior and posterior deltoids (Condition 2). The subacromial space increased in both males and females when the supraspinatus was taped from insertion to origin (Condition 1), but not at a statistically significant level. Condition 3, in which both taping techniques were used simultaneously, did not show an increase at a statistically significant level. CONCLUSIONS: The application of the Kinesio Tape from insertion to muscle origin of the supraspinatus or the anterior and posterior deltoid increased the subacromial joint space. PMID- 29191286 TI - The Validity and Reproducibility of the Flexicurve in the Evaluation of Cervical Spine Lordosis. AB - OBJECTIVE: The purpose of this study was to measure the validity and reliability of flexicurve measurements of cervical curvature in the sagittal plane in adults. METHODS: One hundred thirteen adults were assessed in the seated position with flexicurve radiographs. Two groups were measured: (1) the validity group (n = 55), and (2) the reliability group (n = 58). Both groups were subdivided into 3 subgroups according to body mass index: underweight, normal weight, and overweight. Radiographs were simultaneously taken with flexicurve molded on the cervical spine. Pearson's correlation and the root mean square error were used for the concurrent validity. The reliability of the flexicurve was assessed by 3 raters using the intraclass correlation coefficient (ICC), the standard error of the measurement (SEM), and minimal detectable change (MDC). RESULTS: For the concurrent validity, a high correlation (r = 0.570, P < .001, root mean square error = 9.8 degrees ), and excellent results were obtained for intra-rater (ICC = 0.771, P < .001, SEM = 4.4 degrees , MDC = 8.6 degrees ) and inter-rater (ICC = 0.775, P < .001, SEM = 4.3 degrees , MDC = 8.5 degrees ) reliability. The subgroups had different results, whereas the underweight subgroup consistently had the best results. CONCLUSION: These findings suggest that the flexicurve can be a valid instrument for evaluating the curvature of the cervical spine in the sagittal plane in adults classified according to the body mass index as underweight and normal weight. Reliable measurements were provided for its use whether by the same or different raters. The flexicurve can be recommended for use both in clinical practice and in research settings as long as the suggested protocol is followed. PMID- 29191288 TI - Spinal Manipulative Therapy and Sports Performance Enhancement: A Systematic Review. AB - OBJECTIVE: The purpose of this study was to review the literature regarding the relationship between spinal manipulative therapy (SMT) and sports performance. METHODS: PubMed and Embase databases were searched for original studies published up to July 2016. Inclusion criteria were if SMT has been applied to athletes and if any sports performance-related outcome was measured. RESULTS: Of the 581 potential studies, 7 clinical trials were selected. Most studies had adequate quality (>=6/11) when assessed by the PEDro scale. None of those studies assessed performance at an event or competition. Four studies revealed improvement in a sports performance test after SMT. Meta-analysis could not be performed because of the wide differences in methodologies, design, and outcomes measured. Spinal manipulative therapy influences a wide range of neurophysiological parameters that could be associated with sports performance. Of the 3 studies where SMT did not improve test performance, 2 used SMT not for therapeutic correction of a dysfunctional vertebral joint but to an arbitrary previously set joint. CONCLUSIONS: Although 4 of 7 studies showed that SMT improved sports performance tests, the evidence is still weak to support its use. Spinal manipulative therapy may be a promising approach for performance enhancement that should be investigated with more consistent methodologic designs. PMID- 29191287 TI - A Survey of the Scope of Chiropractic Practice in South Africa: 2015. AB - OBJECTIVES: The purpose of this study was to identify characteristics specific to the chiropractic profession in South Africa and compare them with those of other countries where similar surveys have been conducted. METHODS: This survey utilized a structured questionnaire designed to reflect chiropractic practice in South Africa. The questionnaire was made available online for completion by 714 chiropractic practitioners who were registered with the Allied Health Professions Council of South Africa in 2015. Participation was both voluntary and anonymous. RESULTS: The response rate was 32%; of the respondents, 56% were males and 44% were females. The majority of the respondents had a master's degree in chiropractic. Most participants worked between 31 and 40 hours and saw fewer than 50 patients per week, typically allocating 31 to 45 minutes for initial consultations and 16 to 30 minutes for follow-up visits. Participants saw more female patients than male patients, and most patients were between the ages of 31 and 50 years. Patients typically presented to chiropractors during the acute phase, the primary complaint was low back and pelvic pain/injury without leg pain, and overuse/repetitive stress was reported as being the common etiology. Chiropractors have developed interprofessional referral relationships with general practitioners and massage therapists. CONCLUSIONS: Compared with similar survey analyses from Switzerland, the United Kingdom, and the United States, our findings showed overlap, but some characteristics were unique to the chiropractic profession in South Africa. PMID- 29191289 TI - Introduction: Current preterm birth prevention strategies, Part 2. PMID- 29191290 TI - New techniques in evaluation of the cervix. AB - The process of parturition is poorly understood, but the cervix clearly plays a key role. Because of this, recent research efforts have been directed at objective quantification of cervical remodeling. Investigation has focused on two basic areas: (1) quantification of tissue deformability and (2) presence, orientation, and/or concentration of microstructural components (e.g. collagen). Methods to quantify tissue deformability include strain elastography and shear wave elasticity imaging (SWEI). Methods to describe tissue microstructure include attenuation and backscatter. A single parameter is unlikely to describe the complexities of cervical remodeling, but combining related parameters should improve accuracy of cervical evaluation. This chapter reviews options for cervical tissue characterization. PMID- 29191291 TI - Tocolysis: Present and future treatment options. AB - In the United States, the generally accepted indication for tocolytic therapy centers on suppression of preterm labor. This may be in the form of preventative therapy with progesterone in women with prior spontaneous preterm birth or as an acute intervention to suppress established uterine contractions associated with cervical change occurring at less than 37 weeks gestation. This article seeks to apply this perspective to tocolytic therapy. Here, we provide a review of current tocolytic options and what the last decade of discovery has revealed about the regulation of myometrial excitability and quiescence. Moving forward, we must incorporate the emerging molecular data that is amassing in order to develop novel and effective tocolytic therapeutic options to prevent preterm labor and spontaneous preterm birth (sPTB). PMID- 29191292 TI - Long-term childhood outcomes after interventions for prevention and management of preterm birth. AB - Globally, preterm birth rates are rising and have a significant impact on neonatal morbidity and mortality. Preterm birth remains difficult to prevent and a number of strategies for preterm birth prevention (progesterone, cervical pessaries, cervical cerclage, tocolytics, and antibiotics) have been identified. While some of these show more promise, there is a paucity of evidence regarding the long-term effects of these strategies on childhood outcomes. Strategies used to improve the health of babies if born preterm, such as antenatal magnesium sulfate for fetal neuroprotection and antenatal corticosteroids for fetal lung maturation, show evidence of short-term benefit but lack large-scale follow-up data of long-term childhood outcomes. Future research on preterm birth interventions should include long-term follow-up of the children, ideally with similar outcome measures to allow for future meta-analyses. PMID- 29191293 TI - Cardiac Transplantation: Current Outcomes and Contemporary Controversies. AB - Despite advances in pharmacologic and device treatment of chronic heart failure, long-term morbidity and mortality remain high, and many patients progress to end stage heart failure. Over the last 5 decades, heart transplantation (HTx) has become the preferred therapy for select patients with end-stage heart disease. However, although HTx has become standard of care for the management of end-stage heart failure, challenges continue to exist. The number of patients with end stage heart failure is increasing, whereas the number of donor organs remains constant and a limiting factor in HTx. Not only are there more potential heart transplantation candidates, but HTx candidates today are more complex: older, sensitized, and in need of mechanical circulatory support. Such candidates are at higher risk for poor outcomes including primary graft dysfunction and antibody mediated rejection. This article focuses on current post-transplantation outcomes and recent advances in HTx that could address the current challenges. These advances include: 1) attempts to expand the donor pool; 2) proposed changes in HTx allocation policy for more equitable organ distribution; 3) a better understanding of the definition and management of primary graft dysfunction; and 4) advances in the management of sensitized HTx candidates. Developments in these areas could result in expansion and more equitable distribution of the donor pool and improved survival and quality of life for HTx recipients. PMID- 29191294 TI - Evolving Areas in Heart Transplantation. AB - It has been 50 years since Dr. Christiaan Barnard performed the first human-to human heart transplant in December 1967 in South Africa. Remarkable progress has been made since that time, including changes in surgical techniques, immunosuppression, donor and recipient selection, and post-transplant care. In this paper, we provide a perspective on the changing face of heart transplantation and highlight key evolving areas. Topics that are covered include advances in immunosuppression, screening for acute and chronic rejection, cardiac allograft vasculopathy, and ongoing advancements in cardiac replacement therapy, including xenotransplantation, stem-cell research, tissue engineering, and the total artificial heart. PMID- 29191296 TI - Cardiac Allograft Vasculopathy: It Really Has Changed Over Time. PMID- 29191295 TI - Changes in Outcomes of Cardiac Allograft Vasculopathy Over 30 Years Following Heart Transplantation. AB - OBJECTIVES: This study investigated temporal changes in the demographics and the prognosis of cardiac allograft vasculopathy (CAV) over 30 years following heart transplantation (HTx). BACKGROUND: Effects of the changing HTx demographics on CAV outcomes, based on International Society for Heart and Lung Transplantation (ISHLT) classification of CAV, have been incompletely investigated. METHODS: Patients who underwent HTx at the Montreal Heart Institute were classified according to the severity of CAV (CAV 0 is no presence of CAV; CAV 1 is mild, CAV 2 to 3 is moderate to severe) and era of HTx (early: 1983 to 1998; recent: 1999 to 2011). We compared the risk of progression, survival, and independent predictors of outcomes among the groups. RESULTS: A total of 298 patients were followed for 11.6 +/- 6.6 years. Patients who received transplants in the early era exhibited a higher risk for progression from CAV 1 to a higher grade (adjusted odds ratio: 8.0; 95% confidence interval [CI]: 1.01 to 62.6). The presence of CAV was associated with a significantly increased risk for all-cause mortality in the early era (hazard ratio [HR]: 1.6; 95% CI: 1.1 to 2.5) but not in the recent era (HR: 1.1; 95% CI: 0.2 to 4.9). Regardless of the era, CAV classes 2 to 3 and CAV 1 were associated with a significantly increased risk for all-cause mortality compared to CAV 0 (HR: 6.5; 95% CI: 2.7 to 15.7; and HR: 1.750; 95% CI: 1.001 to 3.046, respectively). CONCLUSIONS: The progression and prognosis of CAV have improved over 30 years. The ISHLT CAV classification accurately and independently predicts long-term outcome following HTx. PMID- 29191297 TI - Verification of Heart Disease: Implications for a New Heart Transplantation Allocation System. AB - OBJECTIVES: This study sought to determine the accuracy of the pre transplantation clinical diagnosis of heart disease in the United Network for Organ Sharing (UNOS) database. BACKGROUND: Because survival on the heart transplantation waitlist depends on underlying heart disease, a new allocation system will include the type of heart disease. Accuracy of the pre transplantation clinical diagnosis and the effect of misclassification are unknown. METHODS: We included all adults who received transplants at our center between January 2009 to December 2015. We compared the pre-transplantation clinical diagnosis at listing with pathology of the explanted heart and determined the potential effect of misclassification with the proposed allocation system. RESULTS: A total of 334 patients had the following clinical cardiac diagnoses at listing: 148 had dilated cardiomyopathy, 19 had restrictive cardiomyopathy, 103 had ischemic cardiomyopathy, 24 had hypertrophic cardiomyopathy, 11 had valvular disease, 16 had congenital heart disease (CHD), and 13 patients had a diagnosis of "other." Pathology of the explanted hearts revealed 82% concordance and 18% discordance (10% coding errors and 8% incorrect diagnosis). The most common incorrect diagnoses were sarcoidosis (66%), arrhythmogenic right ventricular dysplasia (60%), and other causes of predominately right-sided heart failure (33%). Among the misclassified diagnoses, 40% were listed as UNOS status 2, 8% remained at status 2 at transplantation, and only sarcoidosis and CHD were potentially at a disadvantage with the new allocation. CONCLUSIONS: There is high concordance between clinical and pathologic diagnosis, except for sarcoidosis and genetic diseases. Few misclassifications result in disadvantages to patients based on the new allocation system, but rare diseases like sarcoidosis remain problematic. To improve the UNOS database and enhance outcome research, pathology of the explanted hearts should be required post-transplantation.

PMID- 29191299 TI - Implantable Cardioverter-Defibrillators in Patients With a Continuous-Flow Left Ventricular Assist Device: An Analysis of the INTERMACS Registry. AB - OBJECTIVES: This study sought to determine if the presence of implantable cardioverter-defibrillators (ICD) provided a mortality benefit during continuous flow left ventricular assist device (LVAD) support. BACKGROUND: An ICD decreases mortality in selected patients with advanced heart failure and have been associated with reduced mortality in patients with pulsatile LVAD. However, it is unclear whether that benefit extends to patients with a contemporary continuous flow LVAD. METHODS: Propensity score matching was used to generate a cohort of patients with similar baseline characteristics. The primary outcome was freedom from death during LVAD support. Secondary endpoints included freedom from unexpected death, likelihood of transplantation and recovery, and adverse events. RESULTS: Among 16,384 eligible patients in the Interagency Registry for Mechanically Assisted Circulatory Support registry, 2,209 patients with an ICD and 2,209 patients without one had similar propensity scores and were included. The presence of an ICD was associated with an increased mortality risk (hazard ratio: 1.20; 95% confidence interval [CI]: 1.04 to 1.39; p = 0.013) and an increased risk of unexpected death during device support (HR: 1.33; 95% CI: 1.03 to 1.71; p = 0.03). Patients with an ICD were more likely to undergo transplantation (HR: 1.16; 95% CI: 0.99 to 1.35; p = 0.06) and less likely to have LVAD explant for recovery (HR: 0.53, 95% CI: 0.29 to 0.98; p = 0.04). Patients with an ICD had a higher rate of treated ventricular arrhythmias (rate ratio: 1.27; 95% CI: 1.10 to 1.48; p = 0.001) and rehospitalization (rate ratio: 1.08; 95% CI: 1.04 to 1.12; p < 0.0001), but rates of hemorrhagic stroke were similar (rate ratio: 1.01; 95% CI: 0.81 to 1.26; p = 0.98). CONCLUSIONS: Among patients with a continuous flow LVAD, the presence of an ICD was not associated with reduced mortality. PMID- 29191301 TI - Incremental Value of Deformation Imaging and Hemodynamics Following Heart Transplantation: Insights From Graft Function Profiling. AB - OBJECTIVES: This study investigated to define graft dysfunction and to determine its incremental association with long-term outcome after heart transplantation (HT). BACKGROUND: Although graft failure is an established cause of late mortality after HT, few studies have analyzed the prognostic value of graft dysfunction at 1- and 5-year follow-up of HT. METHODS: Patients who underwent HT and completed their first annual evaluation with right heart catheterization and echocardiography at Stanford University between January 1999 and December 2011 were included in the study. Hierarchical clustering was used to identify modules to capture independent features of graft dysfunction at 1 year. The primary endpoint for analysis consisted of the composite of cardiovascular mortality, re transplantation, or heart failure hospitalization within 5 years of HT. The study further explored whether changes in graft dysfunction between 1 and 5 years were associated with 10-year all-cause mortality. RESULTS: A total of 215 HT recipients were included in the study. Using hierarchical clustering, 3 functional modules were identified; among them, left ventricular global longitudinal strain (LVGLS), stroke volume index, and right atrial pressure (RAP) or pulmonary capillary wedge pressure (PCWP) captured key features of graft function. Graft dysfunction based on pre defined LVGLS in absolute value <14%, stroke volume index <35 ml/m2, RAP >10 mm Hg, or PCWP >15 mm Hg were present in 41%, 36%, and 27%, respectively. The primary endpoint at 5 years occurred in 52 patients (24%), whereas 10-year all-cause mortality occurred in 30 (27%) of 110 patients alive at 5 years. On multivariate analysis, RAP (standardized hazard ratio: 1.63), LVGLS (standardized hazard ratio: 1.39), and a history of hemodynamically compromising rejection within 1 year (hazard ratio: 2.18) were independent predictors of 5-year outcome. RAP at 5 years, as well as change in RAP from 1 to 5 years, was predictive of 10-year all-cause mortality. CONCLUSIONS: RAP and LVGLS at the first annual evaluation provide complementary prognostic information in predicting 5-year outcome after HT.

AB - This study aimed to reveal how amoxicillin (AMX) affected the microbial community and the spread mechanism of antibiotic resistance genes (ARGs) in the AMX manufacture wastewater treatment system. For this purpose, a 1.47 L expanded granular sludge bed (EGSB) reactor was designed and run for 241days treating artificial AMX manufacture wastewater. 454 pyrosequencing was applied to analyze functional microorganisms in the system. The antibiotic genes OXA-1, OXA-2, OXA 10, TEM-1, CTX-M-1, class I integrons (intI1) and 16S rRNA genes were also examined in sludge samples. The results showed that the genera Ignavibacterium, Phocoenobacter, Spirochaeta, Aminobacterium and Cloacibacillus contributed to the degradation of different organic compounds (such as various sugars and amines). And the relative quantification of each beta-lactam resistance gene in the study was changed with the increasing of AMX concentration. Furthermore the vertical gene transfer was the main driver for the spread of ARGs rather than horizontal transfer pathways in the system.

AB - Phthalates are a large family of ubiquitous environmental pollutants suspected of being endocrine disruptors. Epidemiological studies have associated phthalate metabolites with decreased reproductive parameters and linked phthalate exposure with the level of urinary 5-methyl-2'-deoxycytidine (5mdC, a product of methylated DNA). In this study, adult male mice were exposed to 450mg di-isobutyl phthalate (DiBP)/(kg.day) via dietary exposure for 28days. Mono-isobutyl phthalate (MiBP, the urinary metabolite) and reproductive function parameters were determined. The levels of 5mdC and 5-hydroxymethyl-2'-deoxycytidine (5hmdC) were measured in urine to evaluate if their contents were also altered by DiBP exposure in this animal model. Results showed that DiBP exposure led to a significant increase in the urinary 5mdC level and significant decreases in sperm concentration and motility in the epididymis, accompanied with reduced testosterone levels and down-regulation of the P450 cholesterol side-chain cleavage enzyme (P450scc) gene in the mice testes. Our findings indicated that exposure to DiBP increased the urinary 5mdC levels, which supported our recent epidemiological study about the associations of urinary 5mdC with phthalate exposure in the male human population. In addition, DiBP exposure impaired male reproductive function, possibly by disturbing testosterone levels; P450scc might be a major steroidogenic enzyme targeted by DiBP or other phthalates. PMID- 29191311 TI - Analysis of PFAAs in American alligators part 1: Concentrations in alligators harvested for consumption during South Carolina public hunts. AB - Environmental contamination resulting from the production or release of harmful chemicals can lead to negative consequences for wildlife and human health. Perfluorinated alkyl acids (PFAAs) were historically produced as protective coatings for many household items and currently persist in the environment, wildlife, and humans. PFAAs have been linked to immune suppression, endocrine disruption, and developmental toxicity in wildlife and laboratory studies. This study examines the American alligator, Alligator mississippiensis, as an important indicator of ecosystem contamination and a potential pathway for PFAA exposure in humans. Alligator meat harvested in the 2015 South Carolina (SC) public hunt season and prepared for human consumption was collected and analyzed for PFAAs to determine meat concentrations and relationships with animal body size (total length), sex, and location of harvest. Of the 15 PFAAs analyzed, perfluorooctane sulfonate (PFOS) was found in all alligator meat samples and at the highest concentrations (median 6.73ng/g). No relationship was found between PFAA concentrations and total length or sex. Concentrations of one or all compounds varied significantly across sampling locations, with alligators harvested in the Middle Coastal hunt unit having the highest PFOS concentrations (median 16.0ng/g; p=0.0001). Alligators harvested specifically from Berkley County, SC (located in the Middle Coastal hunt unit) had the highest PFOS concentrations and the greatest number of PFAAs detected (p<0.0001). The site specific nature of PFAA concentrations in alligator meat observed in this study suggests a source of PFAA contamination in Berkley County, SC.

AB - Enhanced ozonation degradation of atrazine (ATZ) with nano-ZnO (nZnO) as catalyst and the influences of the operational parameters have been investigated through semi-continuous experiments in this study. The results demonstrated that the combination of ozone (O3) and nZnO showed an obvious synergetic effect and the ATZ degradation conformed to pseudo-first-order kinetics. An improvement of ATZ degradation efficiency by 41.8% and pseudo-first-order rate constant by more than a factor of four was obtained in the O3/nZnO process after 5min of reaction compared to O3 alone. Meanwhile, the degradation efficiency of ATZ was gradually enhanced with increasing nZnO dosage and initial pH in the range from 3.0 to 8.0, and a higher amount of ATZ was degraded when the initial concentration of ATZ rose from 0.5 to 5mg/L. Additionally, sulfate ion, chloride ion, nitrate ion and low concentrations of humic acid substances led to enhancement of the ATZ degradation. The notable decrease of ATZ removal efficiency observed in the presence of radical scavengers and the results of free radical tests indicated that OH is the dominant active radical species. The mechanism investigation demonstrated that the enhancement effect could be attributed to the introduction of nZnO, which could promote the utilization of O3, enhance the formation of superoxide radical, and further accelerate the production of hydrogen peroxide and the generation of OH/O2-. PMID- 29191313 TI - Analysis of PFAAs in American alligators part 2: Potential dietary exposure of South Carolina hunters from recreationally harvested alligator meat. AB - Exposure to perfluorinated alkyl acids (PFAAs) has been linked to many harmful health effects including reproductive disorders, developmental delays, and altered liver and kidney function. Most human exposure to environmental contaminants, including PFAAs, occurs through consumption of contaminated food or drinking water. This study uses PFAA data from meat samples collected from recreationally harvested American alligators (Alligator mississippiensis) in South Carolina to assess potential dietary exposure of hunters and their families to PFAAs. Consumption patterns were investigated using intercept surveys of 23 hunters at a wild game meat processor. An exposure scenario using the average consumption frequency, portion size, and median perfluorooctane sulfonic acid (PFOS) concentration in alligator meat from all hunt units found the daily dietary exposure to be 2.11ng/kg body weight per day for an adult human. Dietary PFOS exposure scenarios based on location of harvest suggested the highest daily exposure occurs with alligator meat from the Middle Coastal hunt unit in South Carolina. Although no samples were found to exceed the recommended threshold for no consumption of PFOS found in Minnesota state guidelines, exposure to a mixture of PFAAs found in alligator meat and site-specific exposures based on harvest location should be considered in determining an appropriate guideline for vulnerable populations potentially exposed to PFAAs through consumption of wild alligator meat.

AB - Anaerobic sewage sludge capable of rapidly degrading tetrabromobisphenol A (TBBPA) was successfully acclimated in an anaerobic reactor over 280days. During the period from 0 to 280days, the TBBPA degradation rate (DR), utilization of glucose, and VSS were monitored continuously. After 280days of acclimation, the TBBPA DR of active sludge reached 96.0% after 20days of treatment in batch experiments. Based on scanning electron microscopy (SEM) observations and denaturing gradient gel electrophoresis (DGGE) determinations, the diversity of the microorganisms after 0 and 280days in the acclimated anaerobic sewage sludge was compared. Furthermore, eleven metabolites, including 2-bromophenol, 3 bromophenol, 2,4-dibromophenol, 2,6-dibromophenol, tribromophenol and bisphenol A, were identified by gas chromatography-mass spectrometry (GC-MS). Moreover, the six primary intermediary metabolites were also well-degraded by the acclimated anaerobic sewage sludge to varying degrees. Among the six target metabolites, tribromophenol was the most preferred substrate for biodegradation via debromination. These metabolites degraded more rapidly than monobromide and bisphenol A. The biodegradation data of the intermediary metabolites exhibited a good fit to a pseudo-first-order model. Finally, based on the metabolites, metabolic pathways were proposed. In conclusion, the acclimated microbial consortia degraded TBBPA and its metabolites well under anaerobic conditions. PMID- 29191315 TI - Occurrence and fate of endogenous steroid hormones, alkylphenol ethoxylates, bisphenol A and phthalates in municipal sewage treatment systems. AB - Steroid hormones, alkylphenol ethoxylates (APEOs) and phthalic acid esters (PAEs) are emerging endocrine disrupting chemicals (EDCs) that can interfere with the endocrine function in organisms at low concentrations. The occurrence, distribution behavior, removal rate and the fate of 31 target EDCs in sewage treatment plants, which consist of various treatment facilities and receiving water in Hong Kong, were investigated. Estrone, nonylphenol-di-ethoxylate and diethyl phthalate were found to be dominant in each group of influent samples with concentrations ranging from 11-33, 747-3945 and 445-4635ng/L, respectively. Conversely, progesterone, nonylphenol-mono-ethoxylate and bis (2-ethylhexyl) phthalate were the most abundant in dewatered sludge, with concentrations ranging from 0.9-237, 75-19,743 and 4310-37,016ng/g (dry weight). The removal rates of primary sedimentation and disinfection approaches were lower than 30% for most of the chemicals, while those of activated sludge and reverse osmosis were greater than 80% for more than two-thirds of the compounds, noticeably decreasing the estrogenic risk of sewage discharged into the environment. Steroid hormones were removed via biological degradation, while some APEOs and PAEs adsorbed to the sludge. Victoria Harbor poses a low to medium estrogenic risk mainly contributed by estrone and estradiol and deserves attention.

AB - This study examined concentrations of 15 perfluoroalkyl acids (PFAAs) in tissues from male Mozambique tilapia (Oreochromis mossambicus) collected at Loskop Dam, Mpumalanga, South Africa in 2014 and 2016. Nine of the 15 PFAAs were detected frequently and were included in statistical analysis and included two of the most commonly known PFAAs, perfluorooctanesulfonic acid (PFOS) (median, 41.6ng/g) and perfluorooctanoic acid (PFOA) (median, 0.0825ng/g). Of the tissues measured, plasma (2016 and 2014 median, 22.2ng/g) contained the highest PFAA burden followed by (in descending order): liver (median, 11.6ng/g), kidney (median, 9.04ng/g), spleen (median, 5.92ng/g), adipose (median, 2.54ng/g), and muscle (median, 1.11ng/g). Loskop Dam tilapia have been affected by an inflammatory disease of the adipose tissue known as pansteatitis, so this study also aimed to investigate relationships between PFAA tissue concentrations and incidence of pansteatitis or fish health status. Results revealed that healthy tilapia exhibited an overall higher (p-value<0.05) PFAA burden than pansteatitis-affected tilapia across all tissues. Further analysis showed that organs previously noted in the literature to contain the highest PFAA concentrations, such as kidney, liver, and plasma, were the organs driving the difference in PFAA burden between the two tilapia groups. Care must be taken in the interpretations we draw from not only the results of our study, but also other PFAA measurements made on populations (human and wildlife alike) under differing health status. PMID- 29191317 TI - SeaNine 211 as antifouling biocide: A coastal pollutant of emerging concern. AB - SeaNine 211, with 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT) being the biocidal ingredient, is a widely-used antifouling agent to deter the undesirable biofouling phenomenon. It is commercially promoted as an environmentally acceptable antifoulant mainly due to its claimed rapid degradation in marine environment. However, increasing researches document varying degradative kinetics in different environments, proving that SeaNine 211 is actually not degraded equally fast around the world (half-life between <1day and 13.1days). Large-scale application of SeaNine 211 in antifouling coatings has also caused global contamination of marine environment in various compartments. For example, accumulation of SeaNine 211 is detected as high as 3700ng/L in Spanish seawater and 281ng/g dry weight in Korean sediment. Considering that SeaNine 211 is highly toxic against non-target marine organisms, environmental risk assessment finds that most marine organisms are endangered by SeaNine 211 in worst-case scenario. Its endocrine disrupting and reproductive impairing effects at environmentally worst-case concentrations further constitute a long-term threat to the maintenance of population stability. Therefore, in the light of the varying degradability, environmental pollution and high toxicity, especially the endocrine disruption, SeaNine 211 as an antifouling agent is likely to cause non negligible damages to the marine ecosystem. There is an urgency to perform a systematic ecological risk assessment of SeaNine 211 to prevent the potential impacts on the health of marine environment. A regular monitoring also becomes necessary to place the usage of antifouling biocides under control. PMID- 29191318 TI - Contribution of precursor compounds to the release of per- and polyfluoroalkyl substances (PFASs) from waste water treatment plants (WWTPs). AB - Per- and polyfluoroalkyl substances (PFASs) are ubiquitous in sludge and water from waste water treatment plants, as a result of their incorporation in everyday products and industrial processes. In this study, we measured several classes of persistent PFASs, precursors, transformation intermediates, and newly identified PFASs in influent and effluent sewage water and sludge from three municipal waste water treatment plants in Sweden, sampled in 2015. For sludge, samples from 2012 and 2014 were analyzed as well. Levels of precursors in sludge exceeded those of perfluoroalkyl acids and sulfonic acids (PFCAs and PFSAs), in 2015 the sum of polyfluoroalkyl phosphoric acid esters (PAPs) were 15-20ng/g dry weight, the sum of fluorotelomer sulfonic acids (FTSAs) was 0.8-1.3ng/g, and the sum of perfluorooctane sulfonamides and ethanols ranged from non-detected to 3.2ng/g. Persistent PFSAs and PFCAs were detected at 1.9-3.9ng/g and 2.4-7.3ng/g dry weight, respectively. The influence of precursor compounds was further demonstrated by an observed substantial increase for a majority of the persistent PFCAs and PFSAs in water after waste water treatment. Perfluorohexanoic acid (PFHxA), perfluorooctanoic acid (PFOA), perfluorohexane sulfonic acid (PFHxS), and perfluorooctane sulfonic acid (PFOS) had a net mass increase in all WWTPs, with mean values of 83%, 28%, 37% and 58%, respectively. The load of precursors and intermediates in influent water and sludge combined with net mass increase support the hypothesis that degradation of precursor compounds is a significant contributor to PFAS contamination in the environment. PMID- 29191319 TI - Rate of hexabromocyclododecane decomposition and production of brominated polycyclic aromatic hydrocarbons during combustion in a pilot-scale incinerator. AB - Here, we examined the incineration of extruded polystyrene containing hexabromocyclododecane (HBCD) in a pilot-scale incinerator under various combustion temperatures (800-950 degrees C) and flue gas residence times (2 8sec). Rates of HBCD decomposition ranged from 99.996% (800 degrees C, 2sec) to 99.9999% (950 degrees C, 8sec); the decomposition of HBCD, except during the initial stage of combustion (flue gas residence time<2sec), followed a pseudo first-order kinetics model. An Arrhenius plot revealed that the activation energy and frequency factor of the decomposition of HBCD by combustion were 14.2kJ/mol and 1.69sec-1, respectively. During combustion, 11 brominated polycyclic aromatic hydrocarbons (BrPAHs) were detected as unintentional by-products. Of the 11 BrPAHs detected, 2-bromoanthracene and 1-bromopyrene were detected at the highest concentrations. The mutagenic and carcinogenic BrPAHs 1,5-dibromoanthracene and 1 bromopyrene were most frequently detected in the flue gases analyzed. The total concentration of BrPAHs exponentially increased (range, 87.8-2,040,000ng/m3) with increasing flue gas residence time. Results from a qualitative analysis using gas chromatography/high-resolution mass spectrometry suggest that bromofluorene and bromopyrene (or fluoranthene) congeners were also produced during the combustion. PMID- 29191320 TI - Distribution characteristics of poly- and perfluoroalkyl substances in the Yangtze River Delta. AB - In this work, a method was developed and optimized for the analysis of polyfluoroalkyl and/or perfluoroalkyl substances (PFASs) content in surface water and sediment samples with high instrumental response and good separation. Surface water and sediment samples were collected from the Yangtze River Delta (YRD) to analyze the distribution characteristics of perfluoroalkyl carboxylic acids (PFCAs), perfluoroalkane sulfonic acids (PFSAs), perfluoroalkyl phosphonic acids (PFPAs), perfluoroalkyl phosphinic acids (PFPiAs), and polyfluoroalkyl phosphoric acid diesters (diPAPs). The results showed that the total concentrations of PFCAs and PFSAs in YRD varied from 31 to 902ng/L. PFCAs (>=11 carbons) and PFSAs (>=10 carbons atoms) were not detected in any surface water samples. The mean concentrations of all PFCAs and PFSAs in surface water from the sampling areas decreased in the following order: Yangtze river (191ng/L)~Taihu lake (189ng/L)>Huangpu river (122ng/L)~Qiantang river (120ng/L)>Jiaxing urban river (100ng/L). Strong significant (p<0.05) correlations between the concentrations of many of the compounds were found in the sampling areas, suggesting a common source for these compounds. Only perfluorooctanoic acid (PFOA) was observed in all sediment samples, at concentrations varying from 0.02 to 1.35ng/g. Finally, detection rates of two diPAPs were only 8% and 10%, respectively and the concentration of diPAPs was two to three times lower compared to PFCAs and PFSAs. PMID- 29191321 TI - Abdominal Obesity Is Associated With an Increased Risk of All-Cause Mortality in Patients With HFpEF. AB - BACKGROUND: There is a lack of studies that evaluate the association between abdominal obesity and subsequent outcomes in patients with heart failure with preserved ejection fraction (HFpEF). OBJECTIVES: The present study aimed to assess the association between abdominal obesity and risk of all-cause mortality in patients with HFpEF. METHODS: The present study used data from the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist) trial. The primary outcome was all-cause mortality. We analyzed and compared the hazard ratios (HRs) in patients with abdominal obesity and those without abdominal obesity using multivariable Cox proportional hazard models. Abdominal obesity was defined as a waist circumference of >=102 cm in men and >=88 cm in women. RESULTS: The present study included 3,310 patients with HFpEF: 2,413 patients with abdominal obesity and 897 without abdominal obesity. The mean follow-up was 3.4 +/- 1.7 years. During follow-up, 500 patients died. All-cause mortality rates in patients with and without abdominal obesity were 46.1 and 40.7 events per 1,000 person-years, respectively. After multivariable adjustment, the risk of all-cause mortality was significantly higher in patients with abdominal obesity than in those without abdominal obesity (adjusted HR: 1.52; 95% confidence interval [CI]: 1.16 to 1.99; p = 0.002). The risk of cardiovascular and noncardiovascular mortality was also significantly higher in patients with abdominal obesity than in those without abdominal obesity (adjusted HR: 1.50; 95% CI: 1.08 to 2.08; p = 0.01 and adjusted HR: 1.58; 95% CI: 1.00 to 2.51; p = 0.04, respectively). CONCLUSIONS: The risk of all-cause mortality was significantly higher in patients with HFpEF with abdominal obesity than in those without abdominal obesity.

AB - BACKGROUND: Migraine is a prevalent and disabling disorder. Patent foramen ovale (PFO) has been associated with migraine, but its role in the disorder remains poorly understood. OBJECTIVES: This study examined the efficacy of percutaneous PFO closure as a therapy for migraine with or without aura. METHODS: The PREMIUM (Prospective, Randomized Investigation to Evaluate Incidence of Headache Reduction in Subjects With Migraine and PFO Using the AMPLATZER PFO Occluder to Medical Management) was a double-blind study investigating migraine characteristics over 1 year in subjects randomized to medical therapy with a sham procedure (right heart catheterization) versus medical therapy and PFO closure with the Amplatzer PFO Occluder device (St. Jude Medical, St. Paul, Minnesota). Subjects had 6 to 14 days of migraine per month, had failed at least 3 migraine preventive medications, and had significant right-to-left shunt defined by transcranial Doppler. Primary endpoints were responder rate defined as 50% reduction in migraine attacks and adverse events. Secondary endpoints included reduction in migraine days and efficacy in patients with versus without aura. RESULTS: Of 1,653 subjects consented, 230 were enrolled. There was no difference in responder rate in the PFO closure (45 of 117) versus control (33 of 103) groups. One serious adverse event (transient atrial fibrillation) occurred in 205 subjects who underwent PFO closure. Subjects in the PFO closure group had a significantly greater reduction in headache days (-3.4 vs. -2.0 days/month, p = 0.025). Complete migraine remission for 1 year occurred in 10 patients (8.5%) in the treatment group versus 1 (1%) in the control group (p = 0.01). CONCLUSIONS: PFO closure did not meet the primary endpoint of reduction in responder rate in patients with frequent migraine.

PMID- 29191323 TI - Transcatheter Aortic Valve Replacement in Pure Native Aortic Valve Regurgitation. AB - BACKGROUND: Limited data exist about safety and efficacy of transcatheter aortic valve replacement (TAVR) in patients with pure native aortic regurgitation (AR). OBJECTIVES: This study sought to compare the outcomes of TAVR with early- and new generation devices in symptomatic patients with pure native AR. METHODS: From the pure native AR TAVR multicenter registry, procedural and clinical outcomes were assessed according to VARC-2 criteria and compared between early- and new generation devices. RESULTS: A total of 331 patients with a mean STS score of 6.7 +/- 6.7 underwent TAVR. The early- and new-generation devices were used in 119 patients (36.0%) and 212 patients (64.0%), respectively. STS score tended to be lower in the new-generation device group (6.2 +/- 6.7 vs. 7.6 +/- 6.7; p = 0.08), but transfemoral access was more frequently used in the early-generation device group (87.4% vs. 60.8%; p < 0.001). Compared with the early-generation devices, the new-generation devices were associated with a significantly higher device success rate (81.1% vs. 61.3%; p < 0.001) due to lower rates of second valve implantation (12.7% vs. 24.4%; p = 0.007) and post-procedural AR >= moderate (4.2% vs. 18.8%; p < 0.001). There were no significant differences in major 30 day endpoints between the 2 groups. The cumulative rates of all-cause and cardiovascular death at 1-year follow-up were 24.1% and 15.6%, respectively. The 1-year all-cause mortality rate was significantly higher in the patients with post-procedural AR >= moderate compared with those with post-procedural AR <= mild (46.1% vs. 21.8%; log-rank p = 0.001). On multivariable analysis, post procedural AR >= moderate was independently associated with 1-year all-cause mortality (hazard ratio: 2.85; 95% confidence interval: 1.52 to 5.35; p = 0.001). CONCLUSIONS: Compared with the early-generation devices, TAVR using the new generation devices was associated with improved procedural outcomes in treating patients with pure native AR. In patients with pure native AR, significant post procedural AR was independently associated with increased mortality. PMID- 29191327 TI - Optogenetic Modulation of Cardiac Sympathetic Nerve Activity to Prevent Ventricular Arrhythmias. AB - BACKGROUND: Studies have shown that left stellate ganglion (LSG) suppression protects against ventricular arrhythmias (VAs). Optogenetics is a novel technique to reversibly regulate the activity of the targeted neurons. OBJECTIVES: This study aimed to investigate whether an optogenetically silenced LSG could protect against VAs induced by myocardial ischemia. METHODS: Adeno-associated virus (AAV) was used as the vector to deliver ArchT, an inhibitory light-sensitive opsin, to the LSG neurons. Twenty male beagles were randomized into the optogenetics group (n = 10, AAV2/9-CAG-ArchT-GFP microinjected into LSG) and control group (n = 10, AAV2/9-CAG-GFP microinjected into LSG). After 4 weeks, the LSG function and neural activity, heart rate variability, ventricular action potential duration, and effective refractory period were measured in the absence or presence of a light-emitting diode illumination (565 nm). Myocardial ischemia was induced by left anterior coronary artery ligation and 1 h of electrocardiography was recorded for VAs analysis. RESULTS: ArchT was successfully expressed in all dogs. Transient light-emitting diode illumination significantly suppressed the LSG function, LSG neural activity, and sympathetic nerve indices of heart rate variability as well as prolonged left ventricular effective refractory period and APD90 only in the optogenetics group. Thirty-minute illumination further enhanced these changes in the optogenetics group. Importantly, all of these changes returned to baseline within 2 h after illumination was turned off. Moreover, the ischemia-induced VAs were significantly suppressed by illumination only in the optogenetics group. CONCLUSIONS: Optogenetic modulation could reversibly inhibit the neural activity of LSG, thereby increasing electrophysiological stability and protecting against myocardial ischemia-induced VAs.

AB - BACKGROUND: Little information exists regarding population-based epidemiological changes in infective endocarditis (IE) in Europe. OBJECTIVES: This study sought to analyze temporal trends in IE in Spain from 2003 to 2014. METHODS: This retrospective, population-based, temporal trend study analyzed the incidence, epidemiological and clinical characteristics, and outcome of all patients discharged from hospitals included in the Spanish National Health System with a diagnosis of IE, from January 2003 to December 2014. RESULTS: Overall, 16,867 episodes of IE were identified during the study period, 66.3% in men. The rate of IE significantly increased, from 2.72 in 2003 to 3.49 per 100,000 person-years in 2014, and this rise was higher among older adults. The most frequent microorganisms were staphylococci (28.7%), followed by streptococci (20.4%) and enterococci (13.1%). Twenty-three percent of patients underwent cardiac surgery. The in-hospital mortality rate was 20.4%. Throughout the study period, the proportion of patients with previously known heart valve disease and diabetes mellitus significantly increased, whereas the prevalence of intravenous drug use decreased. Regarding microorganisms, Staphylococcus aureus and streptococci slightly declined, whereas coagulase-negative staphylococci and enterococci consistently increased over the years. In-hospital complications and cardiac surgery rates significantly increased across the years. The risk-adjusted in hospital mortality rate diminished (0.2% per year) during the study period. CONCLUSIONS: The incidence of IE episodes significantly increased over the decade of the study period, particularly among older adults. Relevant changes in clinical and microbiological profile included older patients with more comorbidity and a rise in enterococci and coagulase-negative staphylococcal infections. Adjusted mortality rates slightly declined over the study period. PMID- 29191330 TI - Is Infective Endocarditis Changing Over Time? PMID- 29191333 TI - Current State of Public Reporting.

AB - Regulators and payers have contrasting priorities that can lead to divergent decisions and delays in patient access to new treatments. Those involved in coverage decisions have not routinely been integrated in the drug development process. Theoretically, inclusion of payer representatives early in development could help discern discordance among stakeholder priorities; facilitate cooperation to align objectives; foster agreement on the evidence required for approval and reimbursement; improve transparency, accountability, and consistency of payer decision making; and ideally, minimize delays in patient access to new therapies. However, early participation by payers may not provide these expected benefits if payers' decision-making processes are not evidence based or cannot be reliably predicted. This paper describes current interactions among regulatory agencies, payers, sponsors, and investigators and proposes collaboration among all stakeholders earlier in the development process. The premise that a priori discussions might facilitate the delivery of advances in cardiovascular care is a hypothesis worth testing.

AB - Skin injury is the most common form of child physical abuse. Although the pattern and visual appearance of skin injury and the treatment needed for the injury is similar in children and adults, characteristics of infant and childhood skin may complicate the diagnosis of injury. A good understanding of normal developmental presentation of accidental injury from infancy to adulthood, locations for injury that should trigger consideration of abuse, and cutaneous mimics of abuse across the lifespan are critical to the identification of suspected abuse. Adults and older children can provide a history directly to providers, though it should be noted that abused adults and children may not always disclose the true cause of their injuries. In infants and very young children, a history from the patient is lacking due to the verbal abilities of the child, and a parent or other caregiver may provide a false or misleading history that can complicate the diagnosis and treatment. The approach to taking the history, when abuse is suspected, is a critical part of the evaluation, and best practice will vary depending on whether your patient is a child or an adult. PMID- 29191343 TI - An age-based approach to dermatologic surgery: Kids are not just little people. AB - Surgical dermatologic procedures in children pose unique challenges that differ from those in adults. Child and parental anxiety, along with procedural anxiety in adults, necessitate different approaches. Special considerations are reviewed in the application of topical anesthesia and administration of local anesthesia in children as opposed to adults, and the use and safety of general anesthesia in children is highlighted. In addition, management of postprocedural analgesia differs in children, largely due to concern for safety of opioids in children.

Although similar types of skin tumors can affect both children and adults, the epidemiology, pathogenesis, and treatment of these skin neoplasms can vary drastically in children compared with adults. Despite the clear need for literature elucidating the differences of skin tumors in children compared with adults, there is a serious dearth of scientific contributions addressing this area. This contribution highlights the types of differences that can occur between adults and children with skin neoplasms, as well as the special considerations that need to be recognized when managing skin tumors in children by providing a comparative analysis of basal cell carcinoma, squamous cell carcinoma, and Kaposi sarcoma occurring in adults with these same tumors occurring in children. Specifically, we examine the aforementioned tumors with a focus on (1) epidemiology, (2) etiology, (3) clinical presentation, (4) workup, and (5) treatment.

Cutaneous vasculitis is rare in children, and most childhood vasculitides, of which Henoch Schonlein purpura is the most common, histologically are small vessel leukocytoclastic vasculitis. In children, infectious etiologies are more common than in adults. Childhood cutaneous vasculitis is most often self-limited with a good prognosis, and treatment is mainly supportive.

AB - Granulomatous diseases represent a heterogeneous group of conditions characterized by histiocytic inflammation that affect patients of any age. These diseases differ widely in their pathogenesis and include infectious and noninfectious conditions. This review focuses on noninfectious granulomatous conditions, with particular emphasis on age-related differences in the onset, epidemiology, clinical manifestations, prognosis, and age-specific management of specific granulomatous disorders. Knowledge of age-specific aspects of granulomatous conditions in adults and children improves both the extent of the diagnostic workup and the management of these patients. PMID- 29191348 TI - Cutaneous adverse drug reactions: Kids are not just little people. AB - Cutaneous adverse drug reactions are a common complication of drug therapy and affect patients of all ages. Despite the daunting frequency at which these reactions occur, there are no scientific contributions comparing cutaneous adverse drug reactions in adults to those occurring in children. Literature delineating such differences is important given that there are significant age related differences in the pharmacokinetics of many drugs and that most of the package-insert data on adverse drug reactions are based on preclinical trials that do not include children as participants. This contribution attempts to bridge the literature gap by examining five cutaneous adverse drug reactions that occur in both adults and children, highlighting the many types of age-related differences, with a special emphasis on comparisons of (1) epidemiology, (2) etiology, (3) clinical presentation, (4) workup, and (5) treatment. PMID- 29191349 TI - Clinical trials: Kids are not just little people. AB - Clinical trials are the backbone of modern evidence-based medicine. They are the vital bridge between research-based discovery and cutting edge patient care. Randomized, controlled clinical trials are the gold standard of medical research, providing a method for evaluation and discovery of novel therapies that improve and even save lives. Despite an increase in the number of pediatric and adult clinical trials over recent decades, this growth has not been equal among these populations. The volume of clinical trials involving children lags substantially behind their adult counterparts. Children are not simply little adults. As a result, extrapolating results from adult clinical trials to the treatment of children may be inappropriate and, possibly, harmful. In this review, we discuss the intricacies of performing clinical trials in all patients and stress the unique distinguishing characteristics of pediatric clinical trials. PMID- 29191350 TI - Teledermatology: Kids are not just little people. AB - Teledermatology has emerged as a promising solution for pediatric and adult patients accessing dermatologic care in a health care environment fraught with barriers to access. Teledermatology has been extensively evaluated in terms of diagnostic accuracy, clinical outcomes, patient and provider satisfaction, and costs, relative to traditional health care delivery models. Current research indicates that teledermatology is effective and efficient in diagnosis and management of skin diseases. The majority of studies on the subject, however, rely on adult patient data. Pediatric patients, with their unique clinical features and challenges, may interact with telemedicine differently than their adult counterparts. Maximizing the benefits of teledermatology in pediatric dermatologic care is dependent on future research. We review and analyze the commonalities and differences between pediatric and adult patient care using teledermatology. PMID- 29191351 TI - How issues of autonomy and consent differ between children and adults: Kids are not just little people. AB - Decision making in dermatology practice with adult patients is in most cases a relatively straightforward process, involving a back-and-forth exchange of information, ideas and opinions between the physician and patient. This process is more complex in the field of pediatric dermatology. It involves the triad of the patient, parent or guardian, and physician. It utilizes a model, common to many fields in pediatrics, whereby the physician seeks to obtain informed permission from the parent with the assent of the child, all the while endeavoring to act in the best interests of the child. This model can be challenged in many ways; from parents seeking interventions, which are not in the best interests of the child, to a child refusing to assent to a procedure that is deemed necessary by the parent and physician. We review the theory, terminology, and guidelines relevant to the ethics of decision making when working with children compared with adults. We explore approaches to a variety of ethically challenging situations that may be encountered by the dermatologist, through their work with pediatric patients. PMID- 29191353 TI - Editorial Comment. PMID- 29191352 TI - Predatory journals and dishonesty in science. AB - Predatory magazines are created by unreliable publishers who, after collecting a fee, publish the submitted paper in the Open Access (OA) formula without providing substantive control. For the purpose of "encouraging" authors to submit their work, they often impersonate existing periodicals by using a similar sounding title, a similar webpage, and copied names of editors of the editorial board. They also offer credits close in name to the Impact Factor. The purpose of such activity is to deceive authors and to earn money in an unfair manner. This contribution presents mechanisms used by such journals and includes suggestions for protection from the duplicity and the subsequent disappointment of publishing, often for an exorbitant fee. PMID- 29191354 TI - Alliances: fair or lethal. AB - Alliances are necessary for the development of individuals, institutions, and civilizations. Optimally, alliances provide benefits to their components; nevertheless, gains are not always symmetrical. Some alliances may prove detrimental or even lethal to some or all of the allies. I analyze some types of covenants using examples of history to provide a framework for drawing salient features of the alliance between the legal and the medical professions. This joint effort should be inherently beneficial to both; yet, particularly in the United States, the equilibrium is skewed against the medical profession. If it is not redressed, medicine and its specialties-in particular, dermatology-will go into a decline and wilt. PMID- 29191355 TI - Clinical and prognostic factors in the development of basal cell carcinoma. AB - We investigated the environmental and personal risk factors associated with the development of basal cell carcinoma (BCC). This retrospective cohort study included a total of 997 patients whose diagnosis was confirmed by histopathologic examination between 2007 and 2014. A control examination was performed in 363 of these patients, who were accessed via telephone. A total of 1151 tumors were detected in 997 patients. During their follow-up, 13% of them developed subsequent tumors. The risk of developing subsequent tumor was 2.7-fold higher in patients with multiple BCCs at the time of diagnosis than those with single BCC. Multiple BCCs tended to develop in older patients and men. The risk of developing multiple BCCs was increased in patients with a history of BCC, skin type 1 or 2, and chronic sun exposure (sun exposure of >500 weeks, a high photoaging score [>=30], and the presence of actinic keratosis). We concluded that chronic sun exposure may increase the risk of developing multiple BCCs. These data also indicate that cumulative sun exposure is as important for developing BCC as for squamous cell carcinoma. PMID- 29191356 TI - A novel modality for intraoperative margin assessment and its impact on re excision rates in breast conserving surgery. AB - BACKGROUND: A single center retrospective chart review was performed examining the ability of a novel radiofrequency probe (Margin Probe; Dune Medical Devices, Caesarea, Israel) for intraoperative margin assessment to reduce the number of reexcisions in breast-conserving surgery. METHODS: Reexcision rates were evaluated in one-hundred and twenty consecutive patients before and after the institution of the device. Utility of the device was evaluated by comparing intraoperative feedback with postoperative pathology reports. RESULTS: Two hundred and forty patient subjects were reviewed in total. There was a significant decrease in the re-lumpectomy rate (50%, p = 0.039) in the device group without increasing the total volume of tissue resected. CONCLUSIONS: The use of the MarginProbe device as an adjunct to the standard of care resulted in reduction of positive margins after lumpectomy and the number of re-excisions, significantly improving outcomes in breast-conserving surgery at our institution. PMID- 29191357 TI - Patient-specific evolution of renal function in chronic heart failure patients dynamically predicts clinical outcome in the Bio-SHiFT study. AB - Renal dysfunction is an important component of chronic heart failure (CHF), but its single assessment does not sufficiently reflect clinically silent progression of CHF prior to adverse clinical outcome. Therefore, we aimed to investigate temporal evolutions of glomerular and tubular markers in 263 stable patients with CHF, and to determine if their patient-specific evolutions during this clinically silent period can dynamically predict clinical outcome. We determined the risk of clinical outcome (composite endpoint of Heart Failure hospitalization, cardiac death, Left Ventricular Assist Device placement, and heart transplantation) in relation to marker levels, slopes and areas under their trajectories. In each patient, the trajectories were estimated using repeatedly measured glomerular markers: creatinine/estimated glomerular filtration rate (eGFR), cystatin C (CysC), and tubular markers: urinary N-acetyl-beta-D-glucosaminidase (NAG) and kidney injury molecule (KIM)-1, plasma and urinary neutrophil gelatinase associated lipocalin (NGAL). During 2.2 years of follow-up, we collected on average 8 urine and 9 plasma samples per patient. All glomerular markers predicted the endpoint (univariable hazard ratio [95% confidence interval] per 20% increase: creatinine: 1.18[1.07-1.31], CysC: 2.41[1.81-3.41], and per 20% eGFR decrease: 1.13[1.05-1.23]). Tubular markers, NAG, and KIM-1 also predicted the endpoint (NAG: 1.06[1.01-1.11] and KIM-1: 1.08[1.04-1.11]). Larger slopes were the strongest predictors (creatinine: 1.57[1.39-1.84], CysC: 1.76[1.52 2.09], eGFR: 1.59[1.37-1.90], NAG: 1.26[1.11-1.44], and KIM-1: 1.64[1.38-2.05]). Associations persisted after multivariable adjustment for clinical characteristics. Thus, during clinically silent progression of CHF, glomerular and tubular functions deteriorate, but not simultaneously. Hence, patient specific evolutions of these renal markers dynamically predict clinical outcome in patients with CHF. PMID- 29191358 TI - [Stereotactic body radiation therapy for oligometastatic prostate cancer]. AB - INTRODUCTION: The first line treatment of metastatic prostate cancer is medical or surgical androgen-deprivation. This treatment however has significant side effects that can affect the patients' quality of life. For oligometastatic patients, a new therapeutic approach, focusing on local treatment of metastases, is emerging. METHODS: A systematic review of studies published on Stereotactic Body Radiation Therapy (SBRT) for oligometastatic prostate cancer was performed using results from search request on MEDLINE. RESULTS: Treatment regimens vary from a single fraction of 20Gy (bone lesions) to ten fractions for a total dose of 64Gy (visceral metastases). Local control is 95.5 to 100% at 2 years with grade 1 and 2 toxicities around 10%, without any grade 3 side effects. These retrospective studies show the feasibility and very low toxicity of SBRT for this population of patients. The effect of SBRT on disease-free or global survival and quality of life has not been assessed. Several prospective trials (STOMP & ORIOLE) are underway. CONCLUSION: Treating patients with up to five prostate cancer metastases is efficient and has a low toxicity. Prospective trials should identify which patients, if any, really benefit from this approach. PMID- 29191359 TI - Evaluation of Esophageal Anastomotic Integrity With Serial Pleural Amylase Levels. AB - BACKGROUND: An anastomotic leak is the most devastating and potentially fatal complication after esophagectomy. Current detection methods can be inaccurate and place patients at risk of other complications. Analysis of pleural fluid for amylase may be more accurate and place patients at less of a risk for evaluating the integrity of an esophageal anastomosis. METHODS: We retrospectively reviewed prospective data of 45 consecutive patients who underwent an Ivor Lewis esophagectomy over an 18-month period and evaluated their anastomotic integrity with serial pleural amylase levels (PAL). RESULTS: There were 40 men (89%), and median age was 63 years (range, 35 to 79). Indication for esophagectomy was cancer in 38 patients (84%); 27 (71%) underwent neoadjuvant chemoradiation. A barium swallow was performed in the first 25 patients at median postoperative day (POD) 5 (range, 5 to 10); the swallow was negative in 23 patients (93%). Serial PALs were obtained starting on POD 3 and stopped 1 day after toleration of clear liquids. The PALs in the no-leak patients were highest on POD 3 (median 42 IU/L; range, 20 to 102 IU/L) and decreased (median 15 IU/L; range, 8 to 34 IU/L) to the lowest levels 1 day after clear liquid toleration (p = 0.04). Two patients had a leak and had peak PALs of 227 IU/L and 630 IU/L, respectively; both leaks occurred on POD 4, 1 day before their scheduled swallow test. The last 20 patients underwent serial PALs only, without a planned swallow test or computed tomography scan for anastomotic integrity evaluation. One of these patients had a leak on POD 5 with a low PAL of 55 IU/L the day before the spike of more than 4,000 IU/L. Two of the leaks were treated with esophageal stent placement and intravenous antibiotics, and the remaining patient's leak resolved with intravenous antibiotics, no oral intake, and observation only. None of the leak patients required transthoracic esophageal repair or drainage of an empyema. There was 1 postoperative death (2%) secondary to aspiration pneumonia on POD 10; no leak was ever identified, and the patient had been eating for 3 days before death. Complications occurred in 15 patients (33%), most commonly respiratory; no respiratory issues occurred in PAL-only evaluated patients. No late anastomotic leaks occurred in any patient while in the hospital or after discharge. CONCLUSIONS: Serial PALs for the detection of esophageal anastomotic leaks proved to be accurate, safe, and inexpensive. Elimination of barium swallows and computed tomography scans for evaluation of anastomotic integrity may decrease aspiration risks as well as associated pulmonary failure during the postoperative period. Serial PALs may be the preferred method of detecting an anastomotic leak after esophagectomy. A prospective randomized study is warranted. PMID- 29191360 TI - Early Mentoring of Medical Students and Junior Doctors on a Path to Academic Cardiothoracic Surgery. AB - BACKGROUND: In 2005 the Department of Cardiothoracic Surgery at The Royal Children's Hospital started an early academic mentoring program for medical students and junior doctors with the aim of fostering an interest in academic surgery. METHODS: Between 2005 and 2015, 37 medical students and junior doctors participated in research in the Department of Cardiothoracic Surgery at The Royal Children's Hospital. Each was given an initial project on which to obtain ethics approval, perform a literature review, data collection, statistical analysis, and prepare a manuscript for publication. A search of the names of these former students and doctors was conducted on PubMed to identify publications. RESULTS: A total of 113 journal articles were published in peer-reviewed journals with an average impact factor of 4.1 (range, 1.1 to 19.9). Thirty (30 of 37, 81%) published at least one article. A mean of 4.3 journal articles was published per student or junior doctor (range, 0 to 29). Eleven (11 of 37, 30%) received scholarships for their research. Nine (9 of 37, 24%) have completed or are enrolled in higher research degrees with a cardiothoracic surgery focus. Of these 9, 2 have completed doctoral degrees while in cardiothoracic surgery training. Five will complete their cardiothoracic surgery training with a doctoral degree and the other 2 are pursuing training in cardiology. CONCLUSIONS: A successful early academic mentoring program in a busy cardiothoracic surgery unit is feasible. Mentoring of motivated individuals in academic surgery benefits not only their medical career, but also helps maintain high academic output of the unit. PMID- 29191362 TI - Current conditions and colonization history asymmetrically shape the organization of shallow sessile communities after simulated state shifts. AB - Historical processes affecting biological organization are rarely considered when predicting the effects of disturbance on community structure. In order to assess the relative importance of historical and post-disturbance conditions as determinants of community structure, we undertook reciprocal transplants, at different successional stages, of sessile communities developing at recreational piers that were previously observed to show contrasting fish predation pressure and settlement rate in the Sao Sebastiao Channel, Brazil. Regardless the direction of state shift, after 15 weeks communities converged to the destination site structure, substantially drifting away from the path observed at origin, therefore revealing high susceptibility to environmental change. Although converging, transplanted communities never matched the destination standard in both transplant directions, suggesting that history still mattered, as providing some legacy that lasted, at least, for 15 weeks. The taxonomic groups resisting community drift were hard-bodied invertebrates, which could eventually provide some resilience to these communities through ecosystem engineering. PMID- 29191361 TI - Comparing the effects of fluticasone, anti-IgE and anti-TNF treatments in a chronic asthma model. AB - BACKGROUND: Corticosteroids are used in the treatment of asthma. The aim of this study was to determine the efficacy of anti-IgE and anti-TNF alpha as asthma treatments. METHODS: A mouse model of chronic asthma was developed. The fluticasone group was exposed to fluticasone and the anti-IgE and anti-TNF groups were administered anti-IgE or anti-TNF. IL-4, and IgE levels were measured, and histological analysis, pathological analysis and miRNA-126, miRNA-133a analyses were applied. RESULTS: The cell concentration in the BAL fluid decreased in all the treatment groups. The rate of perivascular and peribronchial cell infiltration decreased in the lung in the high-dose anti-IgE and anti-TNF groups. Smooth muscle thickness decreased in the lung tissue in the low-dose anti-IgE and anti-TNF groups. Bronchial wall thickness decreased in the lung tissue in the fluticasone+anti-IgE group. The IL-4 level in BAL fluid decreased in the high dose anti-IgE, fluticasone+anti-IgE and anti-TNF groups. IgE levels increased in the BAL fluid in the high-dose anti-IgE and anti-TNF groups. The lymphocyte level increased in the BAL fluid in the high-dose anti-IgE group. The macrophage level decreased in the BAL fluid in the anti-TNF group. The relative expression of miRNA-126 increased in all groups. The relative expression of miRNA-133a decreased in the placebo and fluticasone groups. The relative expression of miRNA 133a increased in the low-dose anti-IgE, high-dose anti-IgE, fluticasone+anti-IgE and anti-TNF groups. CONCLUSIONS: The results showed that anti-IgE is successful as a treatment. Fluticasone+anti-IgE and anti-TNF were seen to be superior to other therapeutic modalities when used for prophylaxis. PMID- 29191363 TI - Histopathological proof of the pathogenicity of a rare GFAP mutation in a patient with flaccid paraparesis. AB - Infantile Alexander disease is a rare progressive leukodystrophy caused by autosomal dominant mutations in the (GFAP) gene typically presenting with psychomotor retardation, progressive macrocephaly and refractory epilepsy. Neuroradiological hallmarks are extensive white matter lesions with frontal preponderance as well as signal intensity changes of basal ganglia and medulla oblongata with variable contrast enhancement. Here, we report an atypical manifestation in a 21-month-old boy presenting with flaccid paraparesis and areflexia. Cognitive, visual as well as fine motor skills and muscular strength of the upper extremities were appropriate for age. Weight and height as well as head circumference were within normal range. Clinical or electroencephalographic signs of seizures were absent. Cranial MRI demonstrated bifrontal cystic tumorous lesions with partial contrast rims, as well as space-occupying focal lesions of the caudate nuclei. Spinal MRI revealed swelling of the lumbar and cervical spinal cord. CSF and blood chemistry showed normal results. Histopathology of a subcortical lesion showed large amounts of Rosenthal fibers and protein droplets characteristic of Alexander disease. Sequencing detected a heterozygous mutation of the GFAP gene (c.205G > A; p.(Glu69Lys)) that has been reported before as probably pathogenetic in another case of lower spinal involvement. This well documented case draws attention to atypical spinal manifestations of Alexander disease and gives histopathological proof of the pathogenetic role of a rare GFAP mutation with marked spinal involvement. PMID- 29191365 TI - Trainee Knowledge of Imaging Appropriateness and Safety: Results of a Series of Surveys From a Large Academic Medical Center. AB - OBJECTIVE: In order to provide high quality care to their patients and utilize imaging most judiciously, physician trainees should possess a working knowledge of appropriate use, radiation dose, and safety. Prior work has suggested knowledge gaps in similar areas. We aimed to evaluate the knowledge of imaging appropriateness, radiation dose, and MRI and contrast safety of physician trainees across a variety of specialties. METHODS: Between May 2016 and January 2017, three online surveys were distributed to all interns, residents, and fellows in ACGME accredited training programs at a large academic institution over two academic years. RESULTS: Response rates to three surveys ranged from 17.2% (218 of 1266) for MRI and contrast material safety, 19.1% (242 of 1266) for imaging appropriateness, to19.9% (246 of 1238) for radiation dose. Overall 72% (509 of 706) of survey respondents reported regularly ordering diagnostic imaging examinations, but fewer than half (47.8%; 470 of 984) could correctly estimate radiation dose across four commonly performed imaging studies. Only one third (34%; 167 of 488) of trainees chose appropriate imaging in scenarios involving pregnant patients. Trainee post-graduate year was not significantly correlated with overall radiation safety scores, and no significant difference was found between radiation safety or appropriate imaging scores of those who participated in a medical school radiology elective vs. those who did not. A total of 84% (57 of 68) of radiology trainees and 43% (269 of 630) of non-radiology trainees considered their knowledge adequate but that correlated only weakly correlated to actual knowledge scores (p<0.001). Most trainees (73%, 518 of 706) agreed that more training in these areas would have beneficial effects on patient care. CONCLUSIONS: Knowledge gaps pertaining to appropriateness and imaging safety exist among many trainees. In order to enhance the value of imaging at the population level, further work is needed to assess the most appropriate method and stage of training to address these knowledge gaps. PMID- 29191364 TI - An improved system for grading and treating tinnitus. AB - OBJECTIVE: Tinnitus is an auditory sensation that can cause discomfort or even pain. Because patients with tinnitus frequently have psychological problems, self reporting of the severity of tinnitus is unreliable. We developed a new grading system and practical protocol for the systematic treatment of tinnitus that accounts for its severity, patients' psychological problems, and the frequency of catastrophic episodes. The aim of this study is to employ and validate the new system in patients with tinnitus. METHODS: This study comprised two parts: (i) We identified 113 patients, who were then analyzed in terms of severity of tinnitus, psychological problems, and catastrophic episodes. They were then classified into 5 grades, and the records of their previous treatments were scrutinized. From these records, we designed a practical treatment protocol suitable for each of the 5 grades. (ii) We then identified 82 new patients, and graded and treated them according to the system developed in part (i). Patients were followed-up for at least 6 months; treatment efficacy was evaluated using the pre- and post treatment scores on the Tinnitus Handicap Inventory (THI) and Hospital Anxiety and Depression Scale (HADS). Psychological status was also assessed with the DSM IV. RESULTS: (i) The overall patient group was categorized as follows: Grade I, 38 patients, average THI=37.6 points, average HADS=10.9 points, catastrophic episodes=0 points; Grade II, 24 patients, THI=70.6, HADS=13.1, catastrophic episodes=0; Grade III, 5 patients, THI=73.2, HADS=28.4, catastrophic episodes=0; Grade IV, 33 patients, THI=63.5, HADS=18.8, catastrophic episodes=1.0; Grade V, 13 patients, THI=73.2, HADS=22.4, catastrophic episodes=2.2. The treatment records revealed treatment via psychotropic drugs for 40% of Grade III, 45.5% of Grade IV, and 84.6% of Grade V patients; psychiatric consultation was provided for 20% of Grade III, 12.5% of Grade IV, and 53.8% of Grade V patients. (ii) THI scores improved significantly in Grades II, IV, and V after treatment using the new protocol; HADS scores improved significantly in Grades IV and V. Catastrophic episode scores improved significantly in Grades IV and V. CONCLUSION: We found large enough differences in THI and HADS scores to successfully classify patients with tinnitus into 5 distinct grades that accounted for tinnitus severity, psychological problems, and catastrophic episodes. We found significant improvements in tinnitus severity and psychological problems in the higher (more severe) grades when this system was used to guide treatment. This system not only provided a reasonably reliable categorization system, it simplified treatment without sacrificing efficacy. PMID- 29191366 TI - Cell-Autonomous Metabolic Reprogramming in Hypoxia. AB - Molecular oxygen (O2) is a universal electron acceptor that enables ATP synthesis through mitochondrial respiration in all metazoans. Consequently, hypoxia (low O2) has arisen as an organizing principle for cellular evolution, metabolism, and (patho)biology, eliciting a remarkable panoply of metabolic adaptations that trigger transcriptional, translational, post-translational, and epigenetic responses to determine cellular fitness. In this review we summarize current and emerging cell-autonomous molecular mechanisms that induce hypoxic metabolic reprogramming in health and disease. PMID- 29191367 TI - Heterotypic Ubiquitin Chains: Seeing is Believing. AB - The biological diversity of ubiquitination resides in the multivalent nature of linkage-specific homotypic and heterotypic ubiquitin (Ub) chains. A recent publication by Yau et al. in Cell describes the development of K11/K48-bispecific antibodies and a physiological role for K11/K48 heterotypic chains in regulation of the cell cycle and clearance of aggregated proteins. PMID- 29191368 TI - A novel homozygous nonsense mutation in NEFL causes autosomal recessive Charcot Marie-Tooth disease. AB - The neurofilament light polypeptide (NEFL) gene mutations cause mainly autosomal dominant Charcot-Marie-Tooth disease (CMT) and rarely the recessive forms of CMT. We describe a 13-year-old girl born of consanguineous parents. She presented an early onset of gait disturbance with weakness in lower extremities during the first decade. Nerve conduction velocity of median nerve was 24 m/s and amplitude of compound muscle action potential was 2.2 mV. Sensory nerve action potential was not recordable. Sural nerve biopsy showed severe loss of the large myelinated fibers. Electron microscopy revealed absence of neurofilaments in both myelinated and unmyelinated axons. Genetic analysis identified a novel homozygous nonsense mutation in NEFL c.487G>T (p.Glu163*) as the potential causative mutation in this patient. Our study expands the mutation spectrum of NEFL-related neuropathy. PMID- 29191370 TI - LINC complexes and nuclear positioning. AB - One of the characteristics of eukaryotic cells is their structural plasticity associated with the ability to carry out a broad range of complex functions, both autonomously and as components of tissues and organs. Major cellular rearrangements can be observed in various systems from meiosis in fission yeast, through dermal differentiation in nematodes, to muscle and neuronal development in vertebrates. Each of these processes involves oftentimes dramatic relocation of the nucleus within the cell. During the last decade it has become apparent that the nuclear periphery represents a nexus of cytoskeletal interactions that are involved not only in nuclear movement but also in the distribution and dissemination of mechanical forces throughout the cell. Nucleocytoskeletal coupling is mediated in large part by SUN- and KASH-domain proteins of the nuclear membranes, that together assemble to form LINC (Linker of the Nucleoskeleton and Cytoskeleton) complexes. In this review we will describe how the LINC complex repertoire contributes to nuclear positioning and chromosome dynamics in a variety of cellular contexts. PMID- 29191369 TI - Effect of drying, composting and subsequent impurity removal by sieving on the properties of digestates from municipal organic waste. AB - The application of organic soil amendments is a common measure to prevent structural degradation of agricultural soils and to maintain and improve long term soil fertility. Solid residues from anaerobic digestion of municipal organic waste (MOW) are rich in nutrients and organic matter and have a promising potential to be used as soil amendment. However, no study has related amendment properties of MOW digestate of one origin to different treatment procedures. We therefore investigated the impact of drying, composting and sieving on final digestate properties and specifically nutrient availability and heavy metal and carbon elution. Samples were provided by a semi-industrial two-stage biogas plant with dry fermentation of MOW. Results confirm that in comparison to drying, composting of MOW digestates leads to a significant increase of K, P, Mg, Ca, Cd and Cr in the digestates. Sieving of composted digestates showed that heavy metals are not evenly distributed and that heavy metal concentration in the digestate increases with decreasing mesh sizes (highest concentrations in the fractions <1 mm). Although the element concentration is higher in composted batches, the water-extractability of nutrients, heavy metals and carbon is significantly lower from composted over dried digestates. A significant correlation was found between the dissolution of Zn, Ni, Ca and Mg and pH of eluate as well as dissolved organic carbon (DOC) release (R > 0.7, p<0.05). Results confirm that the extent of carbon elution depends on the degradation rate of digestates. DOC may therefore be a good measure to evaluate digestate stability and to decide on treatment measures. PMID- 29191371 TI - Rat-bite fever due to Streptobacillus notomytis isolated from a human specimen. AB - Rat-bite fever (RBF) is a disease that usually presents with fever, arthralgia and skin rash. Streptobacillus moniliformis was considered the main cause of RBF among the genus Streptobacillus. Although with similar clinical presentation, RBF due to Streptobacillus notomytis is unusual in humans. To the best of our knowledge, we present a case involving the first isolate of S. notomytis in humans. A 63-year-old woman was admitted to our hospital with fever, rash and polyarthritis. She recalled being bitten by a rat on her finger 5 days before presentation. Clinical manifestations were compatible with rat-bite fever (RBF) and the diagnosis was confirmed by the detection of Streptobacillus species from both blood and pustule samples. Initial polymerase chain reaction tests revealed that the organism was S. moniliformis. However, thorough genetic analysis revealed the organism to be S. notomytis. The condition was successfully treated with ampicillin. PMID- 29191372 TI - Th1-related disease development during omalizumab treatment: Two cases with severe asthma.

PMID- 29191374 TI - [Involuntary psychiatric care for inmates in France: Only for "dangerous" patients?] AB - The unites hospitalieres specialement amenagees (UHSA) are full-time inpatient psychiatric units for inmates in France. Their creation has been associated with several advances in access to psychiatric care for inmates in recent years. However, there is still only one means of involuntary hospitalization for prisoners in France: care by decision of a representative of the state (les soins sur decision d'un representant de l'etat [SDRE]). Interestingly, for SDRE to be recognized as legal by the French judge, the patient must be "a danger to himself or to the others". Thus, there is a major difference with involuntary hospitalization outside the prison, and there are specific criteria for involuntary psychiatric hospitalization for inmates in France. This situation questions the general framework of involuntary psychiatric care and is very inconsistent with French law. Indeed, the goal of the loi no 94-43 du 18 janvier 1994 relating to public health and social protection is to ensure equivalent care for all patients, incarcerated or not. PMID- 29191375 TI - Rheumatologic symptoms in oncologic patients on PD-1 inhibitors. AB - OBJECTIVE: Immune checkpoint inhibitors are effective cancer therapies that have been associated with immune-related adverse events (irAEs). Recent reports of irAEs describe symptoms resembling classic rheumatologic syndromes, most notably associated with cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitor blockade. Though cases have been described, there are fewer reports of rheumatologic disease associated with programmed cell death protein-1 (PD-1) inhibitors. Here, we describe a series of four patients presenting to the Brigham and Women's Hospital (BWH) Arthritis Center with de novo polymyalgia rheumatica (PMR)-type conditions and/or peripheral synovitis after treatment with PD-1/PD Ligand 1 (PD-L1) pathway inhibitors. METHODS: Patients with metastatic renal cell carcinoma (RCC) who were treated with PD-1/PD-L1 pathway inhibitors and subsequently developed complaints of new joint pain were referred to the BWH Arthritis Center as part of routine care and identified retrospectively. The electronic medical record was reviewed for cancer history and treatment, rheumatologic symptoms, physical exam, laboratory testing, and clinical course. RESULTS: All four patients developed irAEs consistent with a PMR-type syndrome and/or peripheral synovitis. Symptoms persisted despite discontinuation of the PD 1/PD-L1 pathway inhibitors; however, three of the patients responded well to oral glucocorticoids alone while one patient required the addition of oral methotrexate. All patients had an eventual decline in inflammatory markers. CONCLUSION: These cases highlight the need for both oncologists and rheumatologists to recognize the development of rheumatologic disease during treatment with immune checkpoint blockade. Further investigation is needed to optimize the management of irAEs, particularly considering the increasing use of checkpoint inhibitors to treat malignancies. PMID- 29191376 TI - Clinical, histological, immunological presentations and outcomes of bullous systemic lupus erythematosus: 10 New cases and a literature review of 118 cases. AB - BACKGROUND: Bullous systemic lupus erythematosus (BSLE) is a rare blistering condition associated with systemic lupus erythematosus (SLE). PATIENTS AND METHODS: We conducted a multi-center retrospective study and literature review in order to describe the clinical, immunological, and histological presentations and outcomes of BSLE. The skin biopsies were centrally reviewed, and sera obtained during a flare of BSLE were analyzed for identification of circulating anti basement membrane zone antibodies. RESULTS: Ten patients (all women, median age at SLE diagnosis of 22 years) were included, as well as 118 cases from a systematic review of the literature. Lupus nephritis was associated in 50% of the cases. BSLE presented as tensed bullae on normal or erythematous skin, predominantly localized on the trunk, arms, head, and neck. Urticarial lesions were associated in 31% of the cases, and mucous membrane involvement was seen in 51%. Histological analyses displayed subepidermal detachment, dermal infiltration of polynuclear neutrophils, alignment of these cells at the basal membrane zone and leukocytoclasis. The direct immunofluorescence was polymorphic, showing linear and/or granular deposits of IgG, IgA, IgM, and/or C3. Anti-type VII collagen antibodies were detected in 69% of cases. Dapsone was efficacious in 90% of cases. CONCLUSION: BSLE is rather an autoimmune neutrophilic blistering disease associated with SLE than a cutaneous manifestation and may be associated with active extra-cutaneous manifestations of SLE. Dapsone is the first-choice option.

AB - BACKGROUND: The conventional procedure of the sural neuro-fasciocutaneous flap enables the supply of blood and venous drainage by increasing the width of the adipofascial tissue and preserving tiny venous return routes. Moreover, skin graft is a common method for donor site closure, which may lead to some complications and influence the aesthetic appearance. We report modifications for a distally based sural neuro-fasciocutaneous perforator flap and a relaying flap for donor site closure without skin graft. METHODS: Twelve patients undergoing the modified flap for foot and ankle reconstruction were included in this study between 2014 and 2016. A peroneal-based perforator, a superficial vein, and the vascular axis of the sural nerve were included in the pedicle. A Z-shape skin incision was performed to explore the perforator vessels and a relaying island perforator flap was used to close the donor site. RESULTS: All flaps survived completely without necrosis. The area of the flaps ranged from 16 * 8 cm to 30 * 15 cm. The diameter width of the pedicle ranged from 1.0 to 2.0 cm. A relaying perforator island flap was used in 10 cases for donor site closure and no skin graft was performed. There were no serious donor site complications. All patients were satisfied with the aesthetic outcome postoperatively at the final follow-up. CONCLUSIONS: The distally based sural neuro-fasciocutaneous perforator flap is considered a reliable method for foot and ankle reconstruction. The modification for flap pedicle and donor site closure method without skin graft should be recommended. PMID- 29191378 TI - Patients with head trauma: A study on initial prehospital assessment and care. AB - BACKGROUND: Best evidence guidelines are intended to standardise assessment and treatment of patients with head trauma and improve outcomes for TBI patients. The primary aim was to explore pre-hospital emergency care nurses' (PECNs') documented assessment and care of patients with head trauma and the secondary aim to study gender differences in the documented care and interventions given by the PECNs. METHODS: A retrospective observational study was conducted by evaluating 2750 prehospital medical records. RESULTS: The results showed that 25.2% of the patients were assessed according to all four core-elements in the guidelines and 78.6% of the patients underwent at least one intervention by the PECNs. Male patients were to a higher extent assessed according to guidelines and were given higher transport priority while females were more often assessed for vital parameters and received significantly more analgesics. The assessment documented by the PECNs was not optimal concerning documentation using the Glasgow Coma Scale, but the documented assessment of circulation and, especially, respiratory rate was high (77.2%) compared to previous studies. CONCLUSION: The findings of this study showed a low degree of documented assessment of parameters related to head trauma and might also indicate some gender differences in the assessment and management.

PMID- 29191383 TI - Growth and development in school-age children from Rostov region, Russia: Comparison between urban and rural settings. AB - The purposes of the current study were: (1) to describe growth and physical development and establish norms for schoolchildren from Rostov region in Russia; (2) to compare major characteristics of development between urban and rural children by sex and age. Nearly 200,000 children (198,712) aged between 7 and 17 years from 232 urban and rural schools of Rostov region (Southern Federal District of Russia) participated in the study. School age is a period of intensive growth and physiological and psychological development. Irregularities of personal development are caused by a multitude of factors, such as sex differences, heredity, socio-economic status of a family, standard of living, particular environmental conditions, and lifestyle. It has been established that children from the Southern Federal District of Russia had body mass index values higher than age-appropriate norms for all Russians (Total Russian, Rudnev et al., 2014) and World Health Organization charts. Children from urban settings were taller and heavier than children from rural settings. Sex is one of the most influential factors which play key role in determining specific characteristics of growth and personal development. According to our results, boys and girls both had similar age-related changes in weight and height, but their respective dynamics differed. Girls' height and weight values accelerated at the age 10 to 12 years and plateaued after the age fourteen, whereas in boys height and weight steadily increased with age, showing slight acceleration at the age 12 to 13 years, and reached a plateau by the age of seventeen. PMID- 29191384 TI - The effect of bioresorbable vascular scaffold implantation on distal coronary endothelial function in dyslipidemic swine with and without diabetes. AB - BACKGROUND: We studied the effect of bioresorbable vascular scaffold (BVS) implantation on distal coronary endothelial function, in swine on a high fat diet without (HFD) or with diabetes (DM+HFD). METHODS: Five DM+HFD and five HFD swine underwent BVS implantation on top of coronary plaques, and were studied six months later. Conduit artery segments >5mm proximal and distal to the scaffold and corresponding segments of non-scaffolded coronary arteries, and segments of small arteries within the flow-territory of scaffolded and non-scaffolded arteries were harvested for in vitro vasoreactivity studies. RESULTS: Conduit segments proximal and distal of the BVS edges showed reduced endothelium dependent vasodilation as compared to control vessels (p<=0.01), with distal segments being most prominently affected(p<=0.01). Endothelial dysfunction was only observed in DM+/-HFD swine and was principally due to a loss of NO. Endothelium-independent vasodilation and vasoconstriction were unaffected. Surprisingly, segments from the microcirculation distal to the BVS showed enhanced endothelium-dependent vasodilation (p<0.01), whereas endothelium independent vasodilation and vasoconstriction were unaltered. This enhanced vasorelaxation was only observed in DM+HFD swine, and did not appear to be either NO- or EDHF-mediated. CONCLUSIONS: Six months of BVS implantation in DM+HFD swine causes NO-mediated endothelial dysfunction in nearby coronary segments, which is accompanied by a, possibly compensatory, increase in endothelial function of the distal microcirculation. Endothelial dysfunction extending into coronary conduit segments beyond the implantation-site, is in agreement with recent reports expressing concern for late scaffold thrombosis and of early BVS failure in diabetic patients. PMID- 29191385 TI - Hydrophilic modified magnetic multi-walled carbon nanotube for dispersive solid/liquid phase microextraction of sunitinib in human samples. AB - In this paper, a novel approach for the efficient microextraction and determination of anticancer drug, sunitinib from human samples is described. We synthesized a new nanocomposite; honey coated magnetic multi-walled carbon nanotubes (Honey@magnetic-CNTs). This nanocomposite retains the magnetic properties of individual magnetic nanoparticles (MNPs) and can be effectively separated under an external magnetic field. The synthesized nanoparticles were characterized by FT-IR, VSM, EDAX and XRD and TEM studies. The spherical particles obtained before and after the functionalization had sizes of 14 nm and 16 nm, respectively. The method is based on Honey@magnetic-CNTs assisted dispersive solid-liquid phase microextraction for determination and analysis of the drug. The influences of experimental parameters were investigated. Under optimal conditions, the applied nanocomposite showed good performance, high sensitivity and fast extraction of the analyte from biological samples. In linearity test, the regression correlation coefficient was obtained more than 99% for analyte of interest and linear dynamic range for the proposed method was from 5 to 5000 ng mL-1. Method detection and quantification limits were 1.58 ng mL-1 and 5.28 ng mL-1, respectively. Relative standard deviation was 3.15%.

AB - Accumulating documents have revealed that microRNAs (miRNAs) play critical roles in the development and progression of tumors. MiR-429 has been reported to be involved in regulating various cellular processes. However, its biological role and underlying mechanism in hepatocellular carcinoma (HCC) still need to be further studied. The present study aimed to investigate the function of miR-429 in the progression of HCC. In terms of this paper, it was found that miR-429 was down-regulated in HCC tissues and cells. After being transfected with miR-429 mimics, miR-429 decreased the migratory capacity and reversed the EMT to MET in HCC cells. RAB23 was confirmed as a target of miR-429. Rescue assays further verified that the function of miR-429 in HCC cells was exerted through targeting RAB23. In general, it was concluded that the signal pathway miR-429/RAB23 might be a potential target for HCC treatment. PMID- 29191387 TI - Knowledge translation in tri-sectoral collaborations: An exploration of perceptions of academia, industry and healthcare collaborations in innovation adoption. AB - With the aging population and increase in chronic disease conditions, innovation to transform treatment pathways and service delivery will be necessary. The innovation adoption process however, can take 15 years before widespread adoption occurs in most healthcare systems. Current UK government policies to increase the facilitation of innovation adoption are under way. The aim of this study is to explore perceptions of tri-sectoral collaborations in the healthcare sector. The data in the study are drawn from a cross-sectional survey conducted in 2015 of professionals in academia, industry and the healthcare sectors in England, focusing on Diabetes care. Academia and healthcare respondents had the least work experience outside of their sectors compared to the industry respondents. Healthcare and academia respondents rated the industry sector less trustworthy, unethical, having different goals and less understanding of the other sectors. Industry respondents had a more positive perspective towards potential collaborators. The results from the study demonstrate greater potential challenges to tri-sectoral collaborations and the government's knowledge translation policy, due to pre-conceived notions and lack of understanding of other sectors. The purely structural approach of establishing government mandated translational networks may be insufficient without active attempts to improve collaborative relationships. Mechanisms to facilitate trust building and collaboration are proposed. PMID- 29191388 TI - Tracing the evolution of venom phospholipases A2 in Gloydius strauchii and related pitvipers: A tale of two acidic isozymes. AB - Two acidic Asp49-PLA2s with Glu6 substitution and a neutral Lys49-PLA (designated Gst-K49) were cloned from G. strauchii venom glands, their full amino acid sequences were deduced. The predominant acidic PLA2 (designated Gst-E6a) contains 124 residues and the M18W30 substitutions, while the minor acidic PLA2 (designated Gst-E6b) contains 122 residues and the V18A30 substitutions. Their sequences are most similar to those of the respective orthologous PLA2s of G. intermedius venom. Gst-E6a and Gst-E6b appear to be paralogs and possibly have different predatory targets or functions. The LC-MS/MS results indicate the presence of only three PLA2 gene products in the crude venom, the relative expression levels were in the order of Gst-E6a ? Gst-E6b > Gst-K49, as confirmed by qPCR results. In contrast to other Gloydius, G. strauchii venom does not contain neurotoxic or basic anticoagulant Asp49-PLA2s, but Gst-K49 is the first Lys49-PLA2 identified in Gloydius venoms. However, its venom content is relatively low and its pI value 7.3 is much lower than those of other Lys49-PLA2s and. The Lys49-PLA2 genes appear to regress in the venom of most of Gloydius and related rattlesnake, and this evolutionary regression occurred before the dispersal of Asian pitvipers to the New World.

PMID- 29191390 TI - Efficacy of intraoperative lumbar subarachnoid drainage for prevention of cerebrospinal fluid leak after spinal cord tumor resection. AB - BACKGROUND: Postoperative cerebrospinal fluid (CSF) leakage is a major clinical problem, and prevention of CSF leakage at the surgical site is an important issue. The goal of the study was to evaluate the efficacy of intraoperative lumbar subarachnoid drainage (LSAD) for prevention of CSF leakage after spinal cord tumor resection. METHODS: The subjects were 97 patients with a cervical or thoracic primary intradural spinal cord tumor who underwent surgery at our hospital. A LSAD catheter was placed in the lumbar thecal sac before incision and left in place for several days postoperatively. Age, tumor level, number of laminectomy levels, operation time, estimated blood loss (EBL) intraoperatively, use of artificial dura mater, white blood cell (WBC) counts and C-reactive protein (CRP) levels on postoperative days (PODs) 3 and 10, subcutaneous CSF accumulation at the operation site, and postoperative complications were examined retrospectively. RESULTS: LSAD of CSF was performed in 35 patients. In this group, the drainage catheter was left in place for an average of 4.9 (range 3-8) days. Use of artificial dura mater was significantly higher and CRP on POD 10 was significantly lower in the drainage group. Subcutaneous accumulation of CSF due to leakage was significantly higher in patients with cervical lesions than in those with thoracic lesions. In cases in which artificial dura mater was used, CSF leakage occurred at a significantly lower rate in the drainage group. Without use of an artificial dura mater, CSF leakage did not differ significantly between the two groups. CONCLUSION: Lumbar subarachnoid CSF drainage was associated with a significant decrease in postoperative CRP. In cases in which artificial dura mater was used and in surgery for a cervical lesion, drainage was useful to prevent subcutaneous CSF accumulation. PMID- 29191391 TI - Biphasic lung injury during Streptococcus pneumoniae infection in a murine model. AB - OBJECTIVES: Streptococcus pneumoniae is the leading cause of community-acquired pneumonia. We aimed to analyze the epithelial response to S. pneumoniae-induced lung injury. METHODS: Using an in vitro model with 16HBE cells and experimental in vivo murine model of acute lung injury, we analyzed the epithelial response to S. pneumoniae. Lung epithelial cell monolayers were exposed to S. pneumoniae and permeability was assessed by transepithelial resistance (TER) measurement and organization and expression of junction proteins. Functional consequences were studied with an in vivo murine model measuring alveolar permeability, distal alveolar fluid clearance (DAFC), and the alveolar inflammatory response. RESULTS: In vitro, S. pneumoniae induced a dose-dependent decrease in transepithelial resistance, which was associated with significant modifications in the organization of junction proteins assessed by immunofluorescence staining and expression after 6hours of exposure. In vivo, S. pneumoniae induced a transient increase in alveolar permeability with an adequate increase in DAFC 6hours post infection. In a second phase, a permanent increased permeability was associated with a major decrease in DAFC. CONCLUSION: Overall, the epithelial response to S. pneumoniae followed a biphasic pattern with an initial reversible increase in permeability related to the alteration of tight and adherens junctions and a second phase associated with an epithelial injury with a major increase in permeability with a decreased DAFC reflecting an injured alveolar capillary barrier. PMID- 29191392 TI - Cold atmospheric plasma (CAP) activates angiogenesis-related molecules in skin keratinocytes, fibroblasts and endothelial cells and improves wound angiogenesis in an autocrine and paracrine mode. AB - BACKGROUND: Cold atmospheric plasma (CAP) emerged as a novel therapeutic field with applications developed for bacterial sterilization, wound healing and cancer treatment. For clinical implementation it is important to know how CAP works and which molecular changes occur after the CAP treatment. Vascularization is an important step during wound healing, however, the effects of CAP on wound angiogenesis are not well examined so far. Furthermore, it has not been investigated, whether CAP primarily affects endothelial cells directly or via paracrine mechanisms to modulate the vasculature. OBJECTIVE: This study concentrates on the influence of CAP on angiogenesis-related molecules in human epidermal keratinocytes, dermal fibroblasts and endothelial cells. METHODS: CAP was generated by the MicroPlaSter beta(r) plasma torch system and CAP effects on angiogenesis were determined in vitro and in vivo. RESULTS: We observed that CAP significantly induces the expression of Artemin, EGF, EG-VEGF (PK1), Endothelin-1 (ET-1), FGF-2 (FGF basic), IL-8 (CXCL8) and uPA in keratinocytes and Angiogenin (ANG), Endostatin (Col18A1), MCP-1 (CCL2), MMP-9, TIMP-1, uPA and VEGF in fibroblasts. In addition, CAP activates the expression of Angiopoietin-2 (Ang-2), Angiostatin (PLG), Amphiregulin (AR), Endostatin, FGF-2 and angiogenic-involved receptor expression of FGF R1 and VEGF R1 in HUVEC endothelial cells. It was also demonstrated that supernatants collected from CAP activated fibroblasts and keratinocytes elevate tube formation by endothelial cells and FGF-2 appears to be an important pro-angiogenic factor that controls vascularization via paracrine mechanisms. Mouse experiments supplement that CAP promotes angiogenesis during wound healing in vivo. CONCLUSIONS: Taken together, these results suggest that CAP modulates angiogenesis-involved factors via autocrine and paracrine mechanisms and may be used to affect angiogenesis during wound healing. PMID- 29191393 TI - A novel anti-melanogenic agent, KDZ-001, inhibits tyrosinase enzymatic activity. AB - BACKGROUND: The demand for anti-melanogenic agents is increasing due to the unwanted side effects of current treatments. To find an effective anti melanogenic agent, we used zebrafish as a whole animal model for phenotype-based drug and cosmetic discovery screening. OBJECTIVES: The aim of this study was to identify and explore a small molecule that could be used for skin-whitening cosmetics. METHODS: Using zebrafish embryos, we examined the effects of 1000 compounds on zebrafish development and pigmentation. Pigmentation production was assessed by tyrosinase (TYR) enzymatic activity and melanin contents. Pigmentation marker expression in the human melanoma cell line HMV-II was analyzed by western blot. We also tested reconstituted human skin tissue and analyzed KDZ-001 with computational molecular modeling. RESULTS: We identified three compounds that affected the pigmentation of developing melanophores in zebrafish. Among them, we identified KDZ-001, a novel anti-melanogenic agent, which strongly inhibits melanin synthesis in the developing melanophores of zebrafish, HMV-II cells, and reconstituted human skin with no toxicity. We found that KDZ-001 directly inhibits TYR enzymatic activity. Notably, computational molecular modeling of KDZ-001 suggested that its interaction with copper ions in the active site of TYR is essential for melanin synthesis, further demonstrating that KDZ-001 mainly acts as a TYR inhibitor to synthesize melanin. CONCLUSION: KDZ-001 inhibits melanin synthesis and has a potential for use in skin-whitening cosmetics. PMID- 29191395 TI - A novel cell-based high throughput assay to determine neutralizing antibody titers against circulating strains of rubella virus. AB - A large rubella outbreak occurred in Japan 2013, and 14,344 rubella and 45 congenital rubella syndrome (CRS) cases were reported. At that time, the populational immunity was above the protective threshold assessed by hemmaglutination inhibition (HI) titer. The genotype 2B rubella virus (RV) strains were responsible for the outbreak, which are non-indigenous in Japan. In this work, a cell-based high throughput assay was established to measure the neutralizing antibody (NA) titer against circulating RV isolates. RV infection poorly induces cytopathic effects in tissue culture, preventing the casual measurement of NA titer. Our assay system has overcome this hurdle. Using this assay, we re-evaluated the antibody prevalence rate against circulating viral isolates using human sera collected before the outbreak. Individuals with protective IgG titer (>=10 IU/ml) represented 88.1% of the population. Consistently, 85.2% of the population had protective neutralizing antibody titers (>=1:8) against the vaccine strain. In contrast, 50.5% of the population had protective neutralizing antibody titers against circulating genotype 2B RV strains. These data suggest that the herd immunity assessed by HI titer should have been appreciated deliberately. PMID- 29191396 TI - Blood Lead Levels and Dental Caries in U.S. Children Who Do Not Drink Tap Water. AB - INTRODUCTION: This study's purpose is to determine whether nonconsumption of tap water is associated with lower prevalence of elevated blood lead levels and higher prevalence of dental caries in children and adolescents. METHODS: Cross sectional data from the National Health and Nutrition Examination Survey 2005 2014 recorded drinking water source (n=15,604) and blood lead levels (n=12,373) for participants aged 2-19 years, and dental caries experience for the 2011-2014 subset (n=5,677). The threshold for elevated blood lead level was >=3 MUg/dL. A binary outcome indicated presence or absence of dental caries experience. Multivariable generalized linear models estimated adjusted prevalence ratios with 95% confidence limits. RESULTS: In analysis conducted in 2017, 15% of children and adolescents did not drink tap water, 3% had elevated blood lead levels >=3 MUg/dL, and 50% had dental caries experience. Children and adolescents who did not drink water were less likely than tap water drinkers to have an elevated blood lead level (adjusted prevalence ratios=0.62, 95% confidence limits=0.42, 0.90). Nonconsumers of tap water were more likely to have dental caries (adjusted prevalence ratios=1.13, 95% confidence limits=1.03, 1.23). Results persisted after adjustment for other covariates and using a higher threshold for elevated blood lead level. CONCLUSIONS: In this nationally representative U.S. survey, children and adolescents who did not drink tap water had lower prevalence of elevated blood lead levels and higher prevalence of dental caries than those who drank tap water. PMID- 29191398 TI - The Search for 'Evolution-Proof' Antibiotics. AB - The effectiveness of antibiotics has been widely compromised by the evolution of resistance among pathogenic bacteria. It would be restored by the development of antibiotics to which bacteria cannot evolve resistance. We first discuss two kinds of 'evolution-proof' antibiotic. The first comprises literally evolution proof antibiotics to which bacteria cannot become resistant by mutation or horizontal gene transfer. The second category comprises agents to which resistance may arise, but so rarely that it does not become epidemic. The likelihood that resistance to a novel agent will spread is evaluated here by a simple model that includes biological and therapeutic parameters governing the evolution of resistance within hosts and the transmission of resistant strains between hosts. This model leads to the conclusion that epidemic spread is unlikely if the frequency of mutations that confer resistance falls below a defined minimum value, and it identifies potential targets for intervention to prevent the evolution of resistance. Whether or not evolution-proof antibiotics are ever found, searching for them is likely to improve the deployment of new and existing agents by advancing our understanding of how resistance evolves. PMID- 29191397 TI - The inhibitory effect of Aconiti Sinomontani Radix extracts on the proliferation and migration of human synovial fibroblast cell line SW982. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Aconiti Sinomontani Radix is frequently used in the treatment of Bi syndrome in traditional Chinese medicine. Several reports indicate that Aconiti Sinomontani Radix has therapeutic effects for rheumatoid arthritis (RA). However, the cellular mode of action is still unclear. To investigate the effect of alkaloid extracts of Aconiti Sinomontani Radix on proliferation and migration of human synovial sarcoma SW982 cells as well as the molecular mechanism underlying. MATERIALS AND METHODS: SW982 cells were examined for proliferation by a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) method. Wound scratch assays were performed to assess the migrated rate of SW982 cells. Quantitative real-time PCR was used to measure the mRNA expression levels of Wnt5a, Runx2, MMP3, and Bmp2. Western blotting was used to measure the phosphorylated levels of JNK and NF-kappaB as well as the expression of MMP3. RESULTS: The alkaloid extract from Aconiti Sinomontani Radix (MQA) and MQB, which removed lappaconitine from MQA significantly inhibited the proliferation of SW982 in a dose-dependent manner. The proliferation inhibitory effect of MQB was more potent. Incubation with 10MUg/ml MQB for 12, 24, and 36h inhibited the migration of SW982 cells by 83%, 58%, and 42%, respectively. Treatment with different concentrations of MQB for 24h inhibited mRNA expression of Wnt5a, Runx2, and MMP3, but Bmp2 mRNA expression was elevated by MQB. Further, MQB inhibited phosphorylation of JNK and NF-kappaB p65 as well as MMP3 expression by Western blotting analysis. CONCLUSION: The results showed that MQB inhibited proliferation and migration of SW982 cells possibly through suppressing Wnt5a mediated JNK and NF-kappaB pathways. These results indicated that MQB might be an active extract of Aconiti Sinomontani Radix for targeting fibroblast-like synoviocytes (FLS) and be potential for RA therapy. PMID- 29191399 TI - From Axenic to Mixed Cultures: Technological Advances Accelerating a Paradigm Shift in Microbiology. AB - Since the onset of microbiology in the late 19th century, scientists have been growing microorganisms almost exclusively as pure cultures, resulting in a limited and biased view of the microbial world. Only a paradigm shift in cultivation techniques - from axenic to mixed cultures - can allow a full comprehension of the (chemical) communication of microorganisms, with profound consequences for natural product discovery, microbial ecology, symbiosis, and pathogenesis, to name a few areas. Three main technical advances during the last decade are fueling the realization of this revolution in microbiology: microfluidics, next-generation 3D-bioprinting, and single-cell metabolomics. These technological advances can be implemented for large-scale, systematic cocultivation studies involving three or more microorganisms. In this review, we present recent trends in microbiology tools and discuss how these can be employed to decode the chemical language that microorganisms use to communicate. PMID- 29191394 TI - Medications for alcohol use disorders: An overview. AB - Patients who suffer from alcohol use disorders (AUDs) usually go through various socio-behavioral and pathophysiological changes that take place in the brain and other organs. Recently, consumption of unhealthy food and excess alcohol along with a sedentary lifestyle has become a norm in both developed and developing countries. Despite the beneficial effects of moderate alcohol consumption, chronic and/or excessive alcohol intake is reported to negatively affect the brain, liver and other organs, resulting in cell death, organ damage/failure and death. The most effective therapy for alcoholism and alcohol related comorbidities is alcohol abstinence, however, chronic alcoholic patients cannot stop drinking alcohol. Therefore, targeted therapies are urgently needed to treat such populations. Patients who suffer from alcoholism and/or alcohol abuse experience harmful effects and changes that occur in the brain and other organs. Upon stopping alcohol consumption, alcoholic patients experience acute withdrawal symptoms followed by a protracted abstinence syndrome resulting in the risk of relapse to heavy drinking. For the past few decades, several drugs have been available for the treatment of AUDs. These drugs include medications to reduce or stop severe alcohol withdrawal symptoms during alcohol detoxification as well as recovery medications to reduce alcohol craving and support abstinence. However, there is no drug that completely antagonizes the adverse effects of excessive amounts of alcohol. This review summarizes the drugs which are available and approved by the FDA and their mechanisms of action as well as the medications that are under various phases of preclinical and clinical trials. In addition, the repurposing of the FDA approved drugs, such as anticonvulsants, antipsychotics, antidepressants and other medications, to prevent alcoholism and treat AUDs and their potential target mechanisms are summarized. PMID- 29191400 TI - [Primary care in Portugal]. AB - The economic crisis and deterioration of the Portuguese National Health service has forced professionals to leave the country. The Portuguese National Health System was introduced in 1976, but it has been unable to provide citizens with the social and health advantages of an equality of access and free national health system. The Portuguese National Health System is financed by taxes. However, a 35% of its incomes are from private sources. The health minister decides the budget, and it is based on an historical financing plus a per capita system. Portuguese citizens and immigrants are entitled to free health care, but there is a co-payment for care, diagnostic, pharmacy, and emergency care. Health care provision is a mixture of public and private health care at a regional level. It leads to fragmentation of services and greater inequalities. Doctors are civil servants. Salary is regulated and it depends on seniority and on-call shifts. Primary care activities are similar to those of their Spanish counterparts. General practitioners have gatekeeper function, but the system is imperfect, and patients with private insurance get direct access to the specialist. Specialist training is similar to the training system in Spain. Continuing education is not regulated. The Portuguese Health System has been trying to become a national health system since 1979. Political instability, fragmentation of services, lack of clarity between public and private and co payments are important constraints. Inequalities are an important problem to reconsider while discussing a national health system. PMID- 29191401 TI - Comparative profiling of adrenal steroids in maternal and umbilical cord blood. AB - Fetal steroidome in late pregnancy receives multiple contributions from both maternal and fetal adrenals as well as from placenta. Depressed glucocorticoid levels have been reported in fetal blood at birth, yet studies on mineralocorticoid pathways are sparse. To investigate biosynthesis pathways at birth, adrenal steroids profiles were established in paired mothers and neonates. Forty-six paired healthy term newborns and their mothers from the Aldo cohort were assessed. Steroidomic profiles of mineralocorticoids, glucocorticoids and adrenal androgens were established from umbilical cord and maternal blood at birth using a highly sensitive and specific LC-MS/MS methodology. As compared to maternal blood, umbilical cord blood exhibited high levels of steroids precursors (progesterone and 11-deoxycorticosterone) contrasting with a collapse in corticosterone levels. Consecutively, 18-hydroxycorticosterone and aldosterone levels were also depressed in neonates. Similarly, umbilical cord blood levels of both 17-hydroxyprogesterone and 11-deoxycortisol were higher while cortisol levels sharply decreased. The product-to-substrate ratios evaluating the 11 hydroxylation step (corticosterone/11-deoxycorticosterone and cortisol/11 deoxycortisol) fell for both pathways. As expected, cortisone and 11 dehydrocorticosterone levels exceed those of cortisol and corticosterone in umbilical cord blood reflecting the strong placental 11-beta-hydroxysteroid dehydrogenase type 2 (11betaHSD2) activity. Dehydroepiandrosterone-sulphate levels are higher in neonates, while both androstenedione and testosterone levels sharply fell. No significant difference in steroid levels could be observed according the gender except higher testosterone concentrations in umbilical cord of boys. Moreover, a strong and negative relationship between testosterone and progesterone levels was recorded in umbilical cord of boys. These adrenal steroidomic profiling demonstrate a deficit in mineralocorticoids (aldosterone, 18-hydroxycorticosterone and corticosterone) and glucocorticoids (cortisol) in term neonates, reflecting either a relative defect in 11-hydroxylase activity or more likely the strong placental 11-beta-HSD2 activity. Collectively, these findings should be taken into account for a better understanding of regulatory interactions between placenta and fetal adrenal.

AB - The modeling and simulation software COMSOL Multiphysics(r) was recently extended with an electrophoretic transport interface. Its performance was investigated by comparison to results obtained using the 1D dynamic electrophoresis simulators GENTRANS and SIMUL5. Simulations of zone electrophoresis, isotachophoresis, isoelectric focusing and of an oscillating electrolyte system were performed. Smooth profiles were essentially identical indicating that the COMSOL electrophoretic transport interface is able to reproduce results of the 1D simulators. Differences in the way the respective numerical schemes handle steep concentration gradients and associated instabilities were observed. The COMSOL electrophoretic transport interface is expected to be useful as a general model for simulations in 1D, 2D or 3D geometries, as well as for simulations combining electrophoresis with other physical phenomena.

AB - In the present work, molecularly imprinted polymer (MIP) microspheres were packed in polypropylene hollow fiber (HF) segments for the micro solid-phase extraction and clean-up of thiabendazole (TBZ) in citrus samples. Experimental parameters affecting TBZ extraction were carefully optimized. Hollow fiber membrane was able to protect MIP beads from solid matrix allowing the extraction and clean-up without the inclusion of further filtration and/or centrifugation steps. Under optimum experimental conditions, recoveries for TBZ at 0.83 mg kg-1 concentration level ranged from 5.1 to 6.1%, depending upon the sample analyzed (orange or lemon peel samples), with relative standard deviations (RSDs) lower than 4%. The limits of detection were 0.004 mg kg-1 in orange and 0.009 mg kg-1 in lemon, low enough for the determination of TBZ according to European Union legislation. PMID- 29191403 TI - Laminin-deficient muscular dystrophy: Molecular pathogenesis and structural repair strategies. AB - Laminins are large heterotrimers composed of the alpha, beta and gamma subunits with distinct tissue-specific and developmentally regulated expression patterns. The laminin-alpha2 subunit, encoded by the LAMA2 gene, is expressed in skeletal muscle, Schwann cells of the peripheral nerve and astrocytes and pericytes of the capillaries in the brain. Mutations in LAMA2 cause the most common type of congenital muscular dystrophies, called LAMA2 MD or MDC1A. The disorder manifests mostly as a muscular dystrophy but slowing of nerve conduction contributes to the disease. There are severe, non-ambulatory or milder, ambulatory variants, the latter resulting from reduced laminin-alpha2 expression and/or deficient laminin alpha2 function. Lm-211 (alpha2beta1gamma1) is responsible for initiating basement membrane assembly. This is primarily accomplished by anchorage of Lm-211 to dystroglycan and alpha7beta1 integrin receptors, polymerization, and binding to nidogen and other structural components. In LAMA2 MD, Lm-411 replaces Lm-211; however, Lm-411 lacks the ability to polymerize and bind to receptors. This results in a weakened basement membrane leading to the disease. The possibility of introducing structural repair proteins that correct the underlying abnormality is an attractive therapeutic goal. Recent studies in mouse models for LAMA2 MD reveal that introduction of laminin-binding linker proteins that restore lost functional activities can substantially ameliorate the disease. This review discusses the underlying mechanism of this repair and compares this approach to other developing therapies employing pharmacological treatments.

AB - We have previously reported on the solvent versatility of immobilized amylose and cellulose-based chiral stationary phases in enantioselective liquid chromatographic separation of racemates. The studies were mainly focusing on the tris substituted 3,5-dimethylphenylcarbamate polysaccharide-based chiral stationary phases namely CHIRALPAK IA(r) [Amylose tris (3,5 dimethylphenylcarbamate)] or ADMPC and CHIRALPAK IB(r) [Cellulose tris (3,5 dimethylphenylcarbamate)] or CDMPC. Here we focus on the application of the recently introduced amylose tris (3-chloro-5-methylphenylcarbamate) or ACMPC and brand name CHIRALPAK IG(r) with a chlorine substituent replacing the methyl group in CHIRALPAK IA(r). This was investigated for the enantioslective separation of different classes of pharmaceuticals namely beta- and alpha-blockers, anti inflammatory and antifungal drugs, norepinephrine-dopamine reuptake inhibitor, catecholamines, sedative hypnotics, anti-histaminics, anticancer drugs, antiarrhythmic drugs, flavonoids, amino acids, alpha-2 adrenergic agonist, adrenaline and miscellaneous.A brief comparison between CHIRALPAK IG(r) and CHIRALPAK IA(r) under normal standard, non-standard and reversed mobile phase is demonstrated. The results revealed the versatility of the CHIRALPAK IG(r) column, its compatibility with a wide ranges of solvent and operation modes and its ability to separate chiral compounds not separated with other amylose based chiral stationary phases. PMID- 29191407 TI - Occupational outcomes following combat-related gunshot injury: Cohort study. AB - BACKGROUND: The long-term impact of gun violence on physical function and occupational disability remains poorly explored. We sought to examine the effect of combat-related gunshot injury on work capacity within a cohort of military servicemembers and identify clinical characteristics that influence the capacity to return to work. METHODS: A query was performed to identify all servicemembers injured by gunshot in the years 2005-2009. These soldiers were then followed for a period up to the end of 2014 in order to identify those separated from service due to an inability to perform military duties as a result of their injury. Socio demographic and clinical characteristics were considered co-variates. The dependent variable in this study was inability to effectively return to work, as delineated by the proxy of medical separation from military service. A multivariable logistic regression model was used to evaluate factors associated with an increased likelihood of medical separation following gunshot injury. RESULTS: Of the 1417 individuals meeting inclusion criteria, 40% (n = 572) of the cohort were medically separated in the time-period under study. Significant predictors of separation included non-thoracic injuries, increased injury severity score (ISS; OR 1.05; 95% CI 1.04, 1.06), Senior Enlisted (OR 3.90; 95% CI 2.16, 7.01), and Junior Enlisted military rank (OR 6.99; 95% CI 3.93, 12.44). CONCLUSIONS: This is the largest study in the literature to assess the long-term capacity to return to work following gunshot injury in any population. Individuals in high-demand occupations and those with non-thoracic wounds, or elevated ISS, should be counseled in the post-gunshot injury period regarding the negative associations of these characteristics with the capacity to return to work. Enhanced access to social services in the period following injury could similarly benefit individuals of low socioeconomic background. PMID- 29191408 TI - The retrieval of at least 25 lymph nodes should be essential for advanced gastric cancer patients with lymph node metastasis: A retrospective analysis of single institution database study design: Cohort study. AB - BACKGROUND: Recently, increased evidence have shown that the better prognosis of gastric cancer (GC) patients was associated with the larger number of retrieved lymph nodes (RLNs), but the optimal number of RLNs remains controversial. In the present study, we investigated whether adequate LN retrieval (>=15) was necessary to evaluate the prognosis of patients and attempted to propose an appropriate cutoff-point for the number of RLNs. METHODS: We reviewed 2246 GC patients who underwent radical gastrectomy in our research institution between January 1986 and January 2008. All patients were divided into several groups based on the number of RLNs. The prognostic outcomes of different patient groups were compared and clinicopathologic features were analyzed. RESULTS: In the present study, our results indicated that >=15 RLNs showed a better survival outcome than inadequate LN retrieval (<15), regardless of the node-negative or node-positive GC patients (P < 0.001). For the more advanced GC patients (T2-T4 stage, N1-N3 stage, and stage II-stage III), the retrieval of 25-29 LNs could provide a better survival benefit compared with <25 or >=30 RLNs (P < 0.05). In addition, for the patients who underwent proximal or total gastrectomy, the superior prognosis was still observed in the patient group with 25-29 RLNs. CONCLUSION: The minimal goal of 15 RLNs may not be enough to accurately evaluate prognosis of all patients and at least 25 RLNs should be necessary for advanced GC patients with lymph node metastasis. PMID- 29191409 TI - Reducing the sensation of electrical stimulation with dry electrodes by using an array of constant current sources. AB - Hydrogel electrodes are commonly used for functional and other electrical stimulation applications since the hydrogel layer has been shown to considerably reduce the perception of stimulation compared to dry electrodes. However, these hydrogel electrodes must be changed regularly as they dry out or become contaminated with skin cells and sweat products, thus losing their adhesiveness and resistive properties. Dry electrodes are longer lasting but are more uncomfortable due to unequal current distribution (current hogging). We hypothesise that if current through a dry electrode is equally shared amongst an array of small sub-electrodes, current hogging and thus the sensitivity perceived due to stimulation will be reduced. We constructed an 8 * 8 array of millimetre sized dry electrodes that could either be activated as individual current sources, or together as one large source. A study was performed with 13 participants to investigate the differences in sensation between the two modes of operation. The results showed that 12 out of 13 participants found the new (distributed-constant-current) approach allowed higher stimulation for the same sensation. The differences in sensation between single and multiple sources became larger with higher intensity levels.

AB - INTRODUCTION: The coronary arterial system has been the subject of greater investigation than its venous system due to the importance of human coronary artery disease. With the advent of new percutaneous treatments, the anatomy of the coronary venous system has increasing relevancy. We compared the organization of the coronary venous circulation in three species commonly used in research and compared these to normal humans using both macroscopic anatomic and angiographic studies. ANIMALS: The anatomy of five explanted hearts from healthy dogs, pigs, and sheep were studied macroscopically, and 10 explanted hearts per animal species and 10 clinically normal human were examined by angiography. METHODS: Animal hearts were injected with latex and dissected macroscopically. The coronary venous system of humans was evaluated from clinical angiographic studies. In the animal hearts, a retrograde angiographic study was performed via a Foley catheter in the coronary sinus. RESULTS: The general organization of the coronary venous circulation was similar among humans, dogs, sheep, and pigs. Despite overall similarities to humans, animal hearts demonstrated the absence of the oblique vein of the left atrium and differences in position and organization of venous valves; venous diameters; number of tributary veins; and presence of an anastomosis between the left and right (human anterior and posterior) venous tree. The left azygos of the pig and sheep joined the coronary sinus. CONCLUSIONS: Anatomical differences must be considered when planning biomedical and veterinary studies incorporating cardiac veins. This study provides baseline data regarding structure and organization of the cardiac venous system. PMID- 29191415 TI - Paleoecology of the Serengeti during the Oldowan-Acheulean transition at Olduvai Gorge, Tanzania: The mammal and fish evidence. AB - Eight years of excavation work by the Olduvai Geochronology and Archaeology Project (OGAP) has produced a rich vertebrate fauna from several sites within Bed II, Olduvai Gorge, Tanzania. Study of these as well as recently re-organized collections from Mary Leakey's 1972 HWK EE excavations here provides a synthetic view of the faunal community of Olduvai during Middle Bed II at ~1.7-1.4 Ma, an interval that captures the local transition from Oldowan to Acheulean technology. We expand the faunal list for this interval, name a new bovid species, clarify the evolution of several mammalian lineages, and record new local first and last appearances. Compositions of the fish and large mammal assemblages support previous indications for the dominance of open and seasonal grassland habitats at the margins of an alkaline lake. Fish diversity is low and dominated by cichlids, which indicates strongly saline conditions. The taphonomy of the fish assemblages supports reconstructions of fluctuating lake levels with mass die-offs in evaporating pools. The mammals are dominated by grazing bovids and equids. Habitats remained consistently dry and open throughout the entire Bed II sequence, with no major turnover or paleoecological changes taking place. Rather, wooded and wet habitats had already given way to drier and more open habitats by the top of Bed I, at 1.85-1.80 Ma. This ecological change is close to the age of the Oldowan-Acheulean transition in Kenya and Ethiopia, but precedes the local transition in Middle Bed II. The Middle Bed II large mammal community is much richer in species and includes a much larger number of large-bodied species (>300 kg) than the modern Serengeti. This reflects the severity of Pleistocene extinctions on African large mammals, with the loss of large species fitting a pattern typical of defaunation or 'downsizing' by human disturbance. However, trophic network (food web) analyses show that the Middle Bed II community was robust, and comparisons with the Serengeti community indicate that the fundamental structure of food webs remained intact despite Pleistocene extinctions. The presence of a generalized meat-eating hominin in the Middle Bed II community would have increased competition among carnivores and vulnerability among herbivores, but the high generality and interconnectedness of the Middle Bed II food web suggests this community was buffered against extinctions caused by trophic interactions. PMID- 29191416 TI - Metabolic syndrome in drug naive schizophrenic patients. AB - INTRODUCTION: Research in the last decade tried to focus on natural and unnatural causes of death in schizophrenic patients, but recent few years has focussed on emerging cardio-metabolic risk factors, as a cause of mortality in such patients. AIM OF THE STUDY: To assess the determinant of metabolic syndrome in drug naive schizophrenic patients. METHODOLOGY: It was a cross sectional study; 30 indoor patients with diagnosis of schizophrenia were included. Height, weight, waist circumference and Blood pressure assessment was done by using standard protocol. Fasting Blood Glucose (FBG), Triglyceride (TGs), High Density Lipoprotein (HDL) cholesterol, Low Density Lipoprotein (LDL) total cholesterol were measured. International Diabetes Federation (IDF) criteria was considered for establishing metabolic syndrome. Statistical analysis was done by using chi square and ANOVA. RESULTS: Majority of the patients were females; hailing from rural area; unskilled professional; educated up to below primary level; were single and Hindu by religion. Most common metabolic abnormality was low HDL in 76.6%; High TGs in 26.6%; High SBP >=130mm Hg in 16.67%; DBP>85mm Hg in 13.33%; High FBS 10% of the patients. In risk assessment strongest risk factors for metabolic syndrome were high waist circumference, FBS and TGs. BMI, total cholesterol, LDL and VLDL were also observed as a risk factors in drug naive schizophrenic patients. CONCLUSION: HDL, FBS, TGs, waist circumference and BMI are all the strong risk factors for development of metabolic syndrome in drug naive schizophrenia patients. PMID- 29191417 TI - Effects of Classic Progressive Resistance Training Versus Eccentric-Enhanced Resistance Training in People With Multiple Sclerosis. AB - OBJECTIVE: To compare the effects of classic progressive resistance training (PRT) versus eccentric strength-enhanced training (EST) on the performance of functional tests and different strength manifestations in the lower limb of people with multiple sclerosis (PwMS). DESIGN: Experimental trial. SETTING: Strength training program. PARTICIPANTS: PwMS (N=52; 19 men, 33 women) belonging to MS associations from the Castilla y Leon, Spain. INTERVENTIONS: Participants were assigned to 1 of 2 groups: a control group that performed PRT or an experimental group that performed EST. In both groups, the knee extensor muscles were trained for 12 weeks. MAIN OUTCOME MEASURES: Before and after 12 weeks of training, maximal voluntary isometric contraction and 1 repetition maximum (1RM) of the knee extensors were evaluated, as were the Chair Stand Test (CST) and Timed 8-Foot Up and Go (TUG) functional tests. RESULTS: No differences were found between the groups in the initial values for different tests. Intragroup comparisons found significant differences in CST (F=69.4; P<.001), TUG (F=40.0; P<.001), and 1RM (F=57.8; P<.001). For intergroup comparisons, EST presented better results than PRT in the CST (EST, 4.7%+/-2.8%; PRT, 1.9%+/-2.8%; F=13.1; P=.001) and TUG (EST, -2.9+/-4.7; PRT, -.41+/-5.6; F=5.6; P=.022). CONCLUSIONS: In PwMS, EST leads to improvements in 1RM, TUG, and CST that are similar to those of PRT. However, for patients who participated in this study, the EST seems to promote a better transfer of strength adaptations to the functional tests, which are closer to daily-living activities. PMID- 29191419 TI - Application of guar gum in brine clarification and oily water treatment. AB - The increasing amount of oil wastewater is causing serious damage to the environment. Oily water is a worrisome by-product of the oil industry due to its growing volume in mature basins and complex chemical composition. Low-cost polymers are being used as alternative materials to treat oily waters after treatment by conventional methods, oil and grease (O&G) concentration being the primary parameter for final disposal. In this respect, guar gum can be used to treat petroleum-contaminated waters, with the advantage of being a low-cost, highly-hydrophilic natural polymer. In this study, guar gum, under specific conditions, shapes itself into three-dimensional structures with interesting physicochemical properties. The salting out effect occurs with reticulation of the polymeric chains by borate ions and in the presence of electrolytes, reducing the solubility of the polymeric network in the solution and leading to an electrolyte- and polymer-rich phase. When the guar gum gel was prepared in situ in the produced water, after the salting out effect, the oil was imprisoned in the interstices of the collapsed gel. The gelling guar gum was highly efficient in synthetic oily waters. In the case of initial O&G above 100ppm, the oil removal percentage was above 90%.

AB - In this study, in order to investigate the potential of the novel polysaccharide sacran from Aphanothece Sacrum for development of atopic dermatitis (AD), we evaluated the potential of pretreatment with topical sacran to prevent the development of hapten (dinitrofluorobenzene: DNFB)-induced AD-like disease in mice. In the AD model mice, sacran markedly ameliorated AD symptoms such as scratching behavior and edema in ear. In addition, sacran significantly increased water content of the stratum corneum which regulates the skin barrier function. Furthermore, sacran significantly inhibited inflammatory cytokine and chemokine mRNA levels in the dermatitis skin as well as the IgE antibody level in serum. Sacran inhibited inflammatory cytokines mRNA production from Jurkat cells derived from human leukemia T cells after stimulation with phorbol 12-myristate 13 acetate/ionomycin. Meanwhile, sacran did not inhibit the proliferation of primary B cells stimulated with lipopolysaccharide. These results suggest that sacran has good anti-allergic effect on AD model mice, probably due to the amelioration of skin barrier function and suppression of immune responses. PMID- 29191420 TI - Effect of duration of sonication during gelatinization on properties of tapioca starch water hyacinth fiber biocomposite. AB - This paper characterizes properties of biocomposite sonicated during gelatinization. The biocomposite consisted of tapioca starch based plastic reinforced by 10% volume fraction of water hyacinth fiber (WHF). During gelatinization, the biocomposite was poured into a rectangular glass mold then vibrated in an ultrasonic bath using 40kHz, 250W for varying durations (0, 15, 30, and 60min). The resulting biocomposite was then dried in a drying oven at 50 degrees C for 20h. The results of this study indicate that a biocomposite with optimal properties can be produced using tapioca starch and WHF if the gelatinizing mixture is exposed to ultrasound vibration for 30min. After this vibration duration, tensile strength (TS) and tensile modulus (TM) increased 83% and 108%. A further 60min vibration only increased the TS at 13% and TM at 23%. Moisture resistance of the biocomposite after vibration increased by around 25% reaching a maximal level after 30min. Thermal resistance of the vibrated biocomposites was also increased. PMID- 29191421 TI - Comparative studies of the low-resolution structure of two p23 co-chaperones for Hsp90 identified in Plasmodium falciparum genome. AB - The p23 proteins are small acidic proteins that aid the functional cycle of the Hsp90 molecular chaperone. Such co-chaperone acts by temporarily inhibiting the ATPase activity of Hsp90 and exhibits intrinsic chaperone activity, suggesting independent roles. A search for p23 in the Plasmodium falciparum genome led to the identification of two putative proteins showing 13% identity to each other and approximately 20% identity to human p23. To understand the presence of two p23 proteins in this organism, we generated recombinant p23 proteins (Pfp23A and Pfp23B) and investigated their structure and function. The proteins presented some similarities and dissimilarities in structural contents and showed different chemical and thermal stabilities, with Pfp23A being more stable than Pfp23B, suggesting that these proteins may present different functions in this organism. Both Pfp23 proteins behaved as elongated monomers in solution and were capable of preventing the thermal-induced aggregation of model client proteins with different efficiencies. Finally, the Pfp23 proteins inhibited the ATPase activity of recombinant P. falciparum Hsp90 (PfHsp90). These results validate the studied proteins as p23 proteins and co-chaperones of PfHsp90. PMID- 29191422 TI - Resistant starch produces antidiabetic effects by enhancing glucose metabolism and ameliorating pancreatic dysfunction in type 2 diabetic rats. AB - The aim of the study was to evaluate the hypoglycemic effect of low, medium, and high doses of resistant starch type 2(RS2;100, 150, and 200g/kg) for 28days and explore its potential mechanism of this effect in type 2 diabetic rats treated with high-glucose-fat diet and low-dose streptozotocin(STZ). RS2 treatment induced better regulation of lipid in plasma and liver, fructosamine, oral glucose tolerance test, insulin, glucose metabolism and pancreatic damage in diabetic rats. The best hypoglycemic activity was observed after the medium-dose RS2 treatment. Western blot and real-time Polymerase Chain Reaction (RT PCR)results revealed that phosphoenolpyruvate carboxykinase and glucose-6 phosphatase are involved in glyconeogenesis in the liver, and pancreatic duodenum homeobox 1 controls gluconeogenesis balance by regulating the expression levels of glucose kinase and glucose transport protein 2 in the liver and pancreas. Furthermore, the expression levels of insulin receptor substrate 1 and insulin receptor substrate 2 were enhanced in the pancreas. Results suggested that decreases in the blood glucose levels of diabetic rats fed with RS are regulated through the alteration of the expression levels of the genes related to glucose metabolism and amelioration of pancreatic dysfunction. PMID- 29191423 TI - An electrochemical nitric oxide biosensor based on immobilized cytochrome c on a chitosan-gold nanocomposite modified gold electrode. AB - Goldnanoparticle (AuNPs), chitosan (CS), cytochrome c (Cyt c) and Nafion were immobilized on the surface of a gold electrode to form a Nafion/Cyt c/CS-3 Mercaptopropionic acid (MPA)-AuNPs/cysteamine-MPA (SAMs)-Au electrode. The CS-MPA AuNPs nanocomposite was characterized by UV-vis spectroscopy. Electrochemical behavior of modified electrode was analyzed by electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and chronoamperometry. Uv-vis results showed that CS-MPA-AuNPs nanocomposite could improve electron transfer between Cyt c and electrode surface and keep the catalytic activity of Cyt c. A pair of well defined and reversible redox peaks could be observed for the modified electrode in a 0.1M phosphate buffer solution (PBS, pH 7.0). The anodic and cathodic peak potentials of Cyt c/CS-MPA-AuNPs/SAMs-Au electrode were at 0.006V and -0.043V (vs. Ag/AgCl), respectively. Particular electrocatalytic activity was shown by Cyt c on CS-MPA-AuNPs layer for nitric oxide (NO) reduction. The relationship between peak current and NO concentration was linear in the range of 1*10-7-21.5*10-7M with a detection limit of 0.45*10-7M (S/N=3).The sensitivity was 0.199MUA/MUM. The obtained results indicating that the newly developed biosensor was quite selective and stable which was used for accurate and exact detection of NO. PMID- 29191424 TI - Receptor-mediated targeted delivery of DNA using Lactoferrin nanoparticles. AB - Efficient gene delivery facilitated by non-viral vectors, is comparatively safer alternative than viral carriers. Current approaches to gene delivery largely depends on methods that overcome cellular and tissue barriers impeding efficient DNA delivery. While the conventional delivery systems have the drawback of low cellular uptake and off target effects, the receptor-mediated gene delivery system has shown remarkable breakthrough. In that context exploiting the specific receptor targeting properties of lactoferrin protein, we have developed pDNA loaded lactoferrin protein nanoparticles (pDNA-LfNPs). pDNA-LfNPs were spherical in shape within the size range of 140+/-20nm. They were found to be resistant against nuclease digestion and stable under long storage. Additionally, LfNPs were biocompatible and have targeting ability to facilitate gene uptake by receptor mediated internalization in lactoferrin receptor expressing cell lines. It is also evident from our studies that Lf nanoparticles did not exhibit any cytotoxicity even at the highest concentration. Here we first time report the use of lactoferrin nanoparticles as a gene delivery carrier with targeting abilities.

This splint will be applied several weeks to guide healing in a desired direction. The molding of the nose can be re-sculpted to guide the scarring to a better result. Lightweight, washable, discreet, our splint works to the advantage to be worn without discomfort for several weeks in order to improve the efficiency of contention. PMID- 29191425 TI - GH11 xylanase from Aspergillus tamarii Kita: Purification by one-step chromatography and xylooligosaccharides hydrolysis monitored in real-time by mass spectrometry. AB - The present study describes the one-step purification and biochemical characterization of an endo-1,4-beta-xylanase from Aspergillus tamarii Kita. Extracellular xylanase was purified to homogeneity 7.43-fold through CM cellulose. Enzyme molecular weight and pI were estimated to be 19.5kDa and 8.5, respectively. The highest activity of the xylanase was obtained at 60 degrees C and it was active over a broad pH range (4.0-9.0), with maximal activity at pH 5.5. The enzyme was thermostable at 50 degrees C, retaining more than 70% of its initial activity for 480min. The K0.5 and Vmax values on beechwood xylan were 8.13mg/mL and 1,330.20MUmol/min/mg of protein, respectively. The ions Ba2+ and Ni2+, and the compounds beta-mercaptoethanol and DTT enhanced xylanase activity, while the heavy metals (Co2+, Cu2+, Hg+, Pb2+ and Zn2+) strongly inhibited the enzyme, at 5mM. Enzymatic hydrolysis of xylooligosaccharides monitored in real time by mass spectrometer showed that the shortest xylooligosaccharide more efficiently hydrolyzed by A. tamarii Kita xylanase corresponded to xylopentaose. In agreement, HPLC analyzes did not detect xylopentaose among the hydrolysis products of xylan. Therefore, this novel GH11 endo-xylanase displays a series of physicochemical properties favorable to its application in the food, feed, pharmaceutical and paper industries. PMID- 29191427 TI - Antivirals acting on viral envelopes via biophysical mechanisms of action. AB - Most antivirals target viral proteins and are specific for only one virus, or viral type. Whereas viral proteins are encoded in the plastic viral genome, virion lipids are not and their rearrangements during fusion are conserved among otherwise unrelated enveloped viruses. Antivirals that inhibit these lipid rearrangements could thus pose a high barrier to resistance and have broad spectrum activity. Fusion occurs through a hemifusion stalk in which only the outer leaflets are fused and thus curved with a smaller radius for the polar heads than for the hydrophobic tails (negative curvature). Outer leaflets enriched in phospholipids with head groups of larger cross sections than their lipid tails ("inverted cone") disfavor negative curvature, inhibiting fusion. The rigid amphipathic fusion inhibitors (RAFIs) are synthetic compounds of inverted cone molecular geometry. They inhibit infectivity of otherwise unrelated enveloped viruses. The leading RAFI, aUY11, has an ethynyl-perylene hydrophobic and an uracil-arabinose polar moiety. aUY11 intercalates in viral envelopes and inhibits virion-to-cell fusion of a broad spectrum of otherwise unrelated enveloped viruses. Previous studies showed that amphipathicity, rigidity, and inverted cone molecular geometry were required. We propose that the inverted cone molecular geometry of the RAFIs increases the energy barrier for the hemifusion stalk, inhibiting fusion. Then, chemically distinct compounds with similar amphipathicity, rigidity, and inverted cone shape would have similar antiviral potencies, regardless of specific chemical groups. Alternatively, the perylene group exposed to visible light may induce viral lipid peroxidation. Then, the perylene group and absorbance at visible spectrum would be required. We now evaluated twenty-five chemically distinct RAFIs. The perylene moiety and absorption at visible spectrum were not required, but a minimum length of the hydrophobic moiety was, 10.3 A. The arabino moiety could be modified or replaced by other groups. Cytidine was not tolerated. Bilayer intercalation was required but not sufficient. The vast majority of RAFIs had no overt cytotoxicity (CC50 > 20 MUM; TI > 250-1200). Carbonyl or butylamide substitutions for arabino, or cytidine replacement for uracil, increased cytotoxicity. Cytotoxicity was mainly determined by the polar moiety and there was no correlation between antiviral and cytostatic activities. The definition of the effects of shape and chemical groups of the RAFIs opens the possibility to the rational design of lipid-acting antivirals active against a broad spectrum of enveloped viruses. PMID- 29191428 TI - Monoamine and neuroendocrine gene-sets associate with frustration-based aggression in a gender-specific manner. AB - Investigating phenotypic heterogeneity in aggression and understanding the molecular biological basis of aggression subtypes may lead to new prevention and treatment options. In the current study, we evaluated the taxonomy of aggression and examined specific genetic mechanisms underlying aggression subtypes in healthy males and females. Confirmatory Factor Analysis (CFA) was used to replicate a recently reported three-factor model of the Reactive Proactive Questionnaire (RPQ) in healthy adults (n=661; median age 24.0 years; 41% male). Gene-set association analysis, aggregating common genetic variants within (a combination of) three molecular pathways previously implicated in aggression, i.e. serotonergic, dopaminergic, and neuroendocrine signaling, was conducted with MAGMA software in males and females separately (total n=395) for aggression subtypes. We replicate the three-factor CFA model of the RPQ, and found males to score significantly higher on one of these factors compared to females: proactive aggression. The genetic association analysis showed a female-specific association of genetic variation in the combined gene-set with a different factor of the RPQ; reactive aggression due to internal frustration. Both the neuroendocrine and serotonergic gene-sets contributed significantly to this association. Our genetic findings are subtype- and sex-specific, stressing the value of efforts to reduce heterogeneity in research of aggression etiology. Importantly, subtype- and sex differences in the underlying pathophysiology of aggression suggest that optimal treatment options will have to be tailored to the individual patient. Male and female needs of intervention might differ, stressing the need for sex-specific further research of aggression. Our work highlights opportunities for sample size maximization offered by population-based studies of aggression. PMID- 29191429 TI - Successful Repatriation of Breast Cancer Surveillance for High-Risk Women to the UK National Health Service Breast Screening Programme. AB - BACKGROUND: Since April 2013, the UK's National Health Service Breast Screening Programme (NHSBSP) centers have been obliged to provide services for women at the highest risk of breast cancer, including those carrying highly penetrant single gene mutations (BRCA1, BRCA2, TP53). Since then, such individuals previously undergoing surveillance in the Royal Marsden Hospital were referred to their local NHSBSP centers. We aimed to assess patient experience of surveillance provided by local NHSBSP services at 1 and 3 years after repatriation. PATIENTS AND METHODS: High-risk gene mutation carriers referred to the NHSBSP for breast cancer surveillance were identified from a departmental database in the Cancer Genetics Unit and invited to complete questionnaires about their experience of surveillance under this new pathway, first in 2014 and again in 2016. RESULTS: Three hundred forty-six individuals were invited to participate in 2014, of whom 182 responded (53%). A total of 464 patients were invited in 2016, of whom 246 (53%) completed the second questionnaire. Ninety-four percent of patients with residual breast tissue received some screening at the first (n = 161) and second (n = 185) time points. Ninety-one percent of patients (n = 146) received at least recommended surveillance in the year preceding the initial survey, a proportion decreasing slightly by the second time point (n = 164, 87%). Seventeen percent of individuals required additional diagnostic investigations, with cancers detected in 2%. These proportions remained stable between surveys. CONCLUSION: Repatriation of high-risk individuals from Royal Marsden Hospital to NHSBSP centers has been successfully accomplished. Most individuals received appropriate recommended annual surveillance. Further improvements are required to ensure equal and timely provision of recommended surveillance. PMID- 29191430 TI - Oculomotor abnormalities in children with Niemann-Pick type C. AB - Niemann-Pick type C (NP-C) is a rare recessive disorder associated with progressive supranuclear gaze palsy. Degeneration occurs initially for vertical saccades and later for horizontal saccades. There are studies of oculomotor degeneration in adult NP-C patients [1, 2] but no comparable studies in children. We used high-resolution video-based eye tracking to record monocular vertical and horizontal eye movements in 2 neurological NP-C patients (children with clinically observable oculomotor abnormalities) and 3 pre-neurological NP-C patients (children without clinically observable oculomotor abnormalities). Saccade onset latency, saccade peak velocity and saccade curvature were compared to healthy controls (N=77). NP-C patients had selective impairments of vertical saccade peak velocity and vertical saccade curvature, with slower peak velocities and greater curvature. Changes were more pronounced in neurological than pre neurological patients, showing that these measures are sensitive to disease progress, but abnormal curvature and slowed downward saccades were present in both groups, showing that eye-tracking can register disease-related changes before these are evident in a clinical exam. Both slowing, curvature and the detailed characteristics of the curvature we observed are predicted by the detailed characteristics of RIMLF population codes. Onset latencies were not different from healthy controls. High-resolution video-based eye tracking is a promising sensitive and objective method to measure NP-C disease severity and neurological onset. It may also help evaluate responses to therapeutic interventions. PMID- 29191431 TI - Epidemiological characteristics of lower extremity arterial disease in Chinese diabetes patients at high risk: a prospective, multicenter, cross-sectional study. AB - AIMS: To determine the epidemiological characteristics of lower extremity arterial disease (LEAD) in high-risk patients and identify practical gaps in LEAD management. METHODS: This cross-sectional study consecutively enrolled 10681 patients with type 2 diabetes from 30 hospitals across China from June 2016 to January 2017. All patients were assessed for LEAD by the Ankle-Brachial Index in conjunction with lower limb ultrasonography according to local guidelines. RESULTS: The mean age of patients was 64.2 years, and the median duration of diabetes was 9.0 years. The overall prevalence of LEAD was 21.2%, with 10.6% of patients diagnosed with LEAD before enrollment and 11.8% newly diagnosed at the present visit. Patients with older age, hypertension and dyslipidemia as well as those who smoked were at higher risk of developing LEAD. Only 55.0%, 28.2%, and 42.5% of participating patients reached the guideline-recommended goals for glycemic, blood pressure, and lipid control, respectively. Anti-hypertensive agents, lipid lowering therapies, anti-platelet agents, and vasodilators were underused, especially in newly diagnosed LEAD patients (44.1%, 46.2%, 35.3%, and 31.7%, respectively). CONCLUSIONS: Despite the high prevalence of LEAD, it was still found to be underdiagnosed and undertreated in Chinese diabetes patients. More efforts should be directed at encouraging awareness of early LEAD and achieving guideline-recommended goals in type 2 diabetes patients. PMID- 29191432 TI - Cereal fiber, fruit fiber, and type 2 diabetes: Explaining the paradox. AB - While the relationship between dietary fiber and type 2 diabetes mellitus (T2DM) has been much studied, the evidence about its role in the prevention and control of this condition has been conflicting. We critically evaluate prospective cohort studies and randomized controlled trials (RCTs) that examined insoluble/nonviscous/cereal fiber and soluble/viscous/fruit fiber in relation to risk of T2DM. Taken as a whole this evidence indicates that, in the quantities typically eaten, cereal fiber is protective against T2DM while fruit fiber gives little protection. We argue that the protective action of cereal fiber may be explained by the modulating effects of gut microbiota through mechanisms such as: 1) improving glucose tolerance via energy metabolism pathways (colonic fermentation and generation of short-chain fatty acids); 2) reducing inflammation; and 3) altering the immune response. By gaining more knowledge of specific host and gut microbial functional pathways involved in T2DM development and the potential role of cereal fiber, appropriate disease prevention and intervention strategies may be developed. PMID- 29191433 TI - How does globalisation affect women's health? PMID- 29191435 TI - There is no weekend effect in hip fracture surgery - A comprehensive analysis of outcomes. AB - BACKGROUND: Previous studies have shown that some patient groups suffer adverse outcomes if they are acutely admitted to hospital over a weekend. We aimed to investigate this 'weekend effect' at our centre in patients presenting with a hip fracture. METHODS: Consecutive patients undergoing acute hip fracture surgery were identified from a prospective database. Patient demographics, co morbidities, fracture type, admission blood parameters were examined. Outcomes analysed included 30-day, 90-day and 1-year mortality as well as length of stay, re-operations and delay to surgery. The data were analysed with regards to day of admission and day of surgery separately. RESULTS: A total of 1326 patients were included, of which 368 patients were admitted over a weekend and 411 patients had their operation over a weekend. Overall 30-day mortality was 7.6% (101 patients), whilst the 90-day and 1-year mortalities were 15.3% and 26.8% (203 and 356 patients). There were no significant differences in any of the outcomes based on the day of admission or the day of surgery. Multivariate analysis for 30-day mortality demonstrated the following variables to be significant predictors: admission urea levels (hazard ratio (HR) 1.042, p = 0.027), age (HR 1.058, p < 0.001), admission source (HR 1.428, p < 0.001), surgical delay >48 h (HR 1.853, p = 0.004), male gender (HR 1.967, p = 0.003), previous stroke (HR 2.261, p = 0.038), acute chest infection (4.240, p < 0.001) and chronic liver disease (HR 4.581, p = 0.014). CONCLUSION: This data suggests that there is no significant weekend effect in hip fracture surgery and mortality is affected by patient co morbidities and delay to surgery. PMID- 29191434 TI - The gendered effects of foreign investment and prolonged state ownership on mortality in Hungary: an indirect demographic, retrospective cohort study. AB - BACKGROUND: Research on the health outcomes of globalisation and economic transition has yielded conflicting results, partly due to methodological and data limitations. Specifically, the outcomes of changes in foreign investment and state ownership need to be examined using multilevel data, linking macro-effects and micro-effects. We exploited the natural experiment offered by the Hungarian economic transition by means of a multilevel study designed to address these gaps in the scientific literature. METHODS: For this indirect demographic, retrospective cohort study, we collected multilevel data related to Hungary between 1995 and 2004 from the PrivMort database and other sources at the town, company, and individual level to assess the relation between the dominant company ownership of a town and mortality. We grouped towns into three ownership categories: dominant state, domestic private, and foreign ownership. We did population surveys in these towns to collect data on vital status and other characteristics of survey respondents' relatives. We assessed the relation between dominant ownership and mortality at the individual level. We used discrete-time survival modelling, adjusting for town-level and individual-level confounders, with clustered SEs. FINDINGS: Of 83 eligible towns identified, we randomly selected 52 for inclusion in the analysis and analysed ownership data from 262 companies within these towns. Additionally, between June 16, 2014, and Dec 22, 2014, we collected data on 78 622 individuals from the 52 towns, of whom 27 694 were considered eligible. After multivariable adjustment, we found that women living in towns with prolonged state ownership had significantly lower odds of dying than women living in towns dominated by domestic private ownership (odds ratio [OR] 0.74, 95% CI 0.61-0.90) or by foreign investment (OR 0.80, 0.69-0.92). INTERPRETATION: Prolonged state ownership was associated with protection of life chances during the post-socialist transformation for women. The indirect economic benefits of foreign investment do not translate automatically into better health without appropriate industrial and social policies. FUNDING: The European Research Council. PMID- 29191436 TI - Systematic profiling of alternative splicing signature reveals prognostic predictor for ovarian cancer. AB - OBJECTIVE: The majority of genes are alternatively spliced and growing evidence suggests that alternative splicing is modified in cancer and is associated with cancer progression. Systematic analysis of alternative splicing signature in ovarian cancer is lacking and greatly needed. METHODS: We profiled genome-wide alternative splicing events in 408 ovarian serous cystadenocarcinoma (OV) patients in TCGA. Seven types of alternative splicing events were curated and prognostic analyses were performed with predictive models and splicing network built for OV patients. RESULTS: Among 48,049 mRNA splicing events in 10,582 genes, we detected 2,611 alternative splicing events in 2,036 genes which were significant associated with overall survival of OV patients. Exon skip events were the most powerful prognostic factors among the seven types. The area under the curve of the receiver-operator characteristic curve for prognostic predictor, which was built with top significant alternative splicing events, was 0.937 at 2,000 days of overall survival, indicating powerful efficiency in distinguishing patient outcome. Interestingly, splicing correlation network suggested obvious trends in the role of splicing factors in OV. CONCLUSIONS: In summary, we built powerful prognostic predictors for OV patients and uncovered interesting splicing networks which could be underlying mechanisms. PMID- 29191437 TI - Urinary diversion in the genitourinary cancer survivor. AB - Urinary diversion has been in the scope of practice of Gynecologic Oncologists since the inception of the sub-specialty. However, many fewer urinary diversions are performed currently than in the past due to improved prevention of cervical cancer. The intent of this article is to provide a state of the art review for Gynecologic Oncologists. Surgeons performing these complex procedures must be knowledgeable about the differences between various types of continent and non continent urinary diversions, and the principles of pre and post-operative care. This includes the indications for surgery and pre-operative considerations, types of urinary diversion including continent and non-continent diversions, and the need for long-term follow-up with patients who undergo urinary diversion requiring lifelong follow up and testing for surveillance of the upper urinary tracts and to monitor for nutritional and metabolic alterations. PMID- 29191438 TI - Real-time EEG-defined excitability states determine efficacy of TMS-induced plasticity in human motor cortex. AB - BACKGROUND: Rapidly changing excitability states in an oscillating neuronal network can explain response variability to external stimulation, but if repetitive stimulation of always the same high- or low-excitability state results in long-term plasticity of opposite direction has never been explored in vivo. OBJECTIVE/HYPOTHESIS: Different phases of the endogenous sensorimotor MU-rhythm represent different states of corticospinal excitability, and repetitive transcranial magnetic stimulation (rTMS) of always the same high- vs. low excitability state results in long-term plasticity of different direction. METHODS: State-dependent electroencephalography-triggered transcranial magnetic stimulation (EEG-TMS) was applied to target the EEG negative vs. positive peak of the sensorimotor MU-rhythm in healthy subjects using a millisecond resolution real-time digital signal processing system. Corticospinal excitability was indexed by motor evoked potential amplitude in a hand muscle. RESULTS: EEG negative vs. positive peak of the endogenous sensorimotor MU-rhythm represent high- vs. low-excitability states of corticospinal neurons. More importantly, otherwise identical rTMS (200 triple-pulses at 100 Hz burst frequency and ~1 Hz repetition rate), triggered consistently at this high-excitability vs. low excitability state, leads to long-term potentiation (LTP)-like vs. no change in corticospinal excitability. CONCLUSIONS: Findings raise the intriguing possibility that real-time information of instantaneous brain state can be utilized to control efficacy of plasticity induction in humans. PMID- 29191439 TI - Effects of cerebellar neuromodulation in movement disorders: A systematic review. AB - BACKGROUND: The cerebellum is involved in the pathophysiology of many movement disorders and its importance in the field of neuromodulation is growing. OBJECTIVES: To review the current evidence for cerebellar modulation in movement disorders and its safety profile. METHODS: Eligible studies were identified after a systematic literature review of the effects of cerebellar modulation in cerebellar ataxia, Parkinson's disease (PD), essential tremor (ET), dystonia and progressive supranuclear palsy (PSP). Neuromodulation techniques included transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS) and deep brain stimulation (DBS). The changes in motor scores and the incidence of adverse events after the stimulation were reviewed. RESULTS: Thirty four studies were included in the systematic review, comprising 431 patients. The evaluation after stimulation ranged from immediately after to 12 months after. Neuromodulation techniques improved cerebellar ataxia due to vascular or degenerative etiologies (TMS, tDCS and DBS), dyskinesias in PD patients (TMS), gross upper limb movement in PD patients (tDCS), tremor in ET (TMS and tDCS), cervical dystonia (TMS and tDCS) and dysarthria in PSP patients (TMS). All the neuromodulation techniques were safe, since only three studies reported the existence of side effects (slight headache after TMS, local skin erythema after tDCS and infectious complication after DBS). Eleven studies did not mention if adverse events occurred. CONCLUSIONS: Cerebellar modulation can improve specific symptoms in some movement disorders and is a safe and well-tolerated procedure. Further studies are needed to lay the groundwork for new researches in this promising target. PMID- 29191441 TI - Inadequate HIV care after incarceration: case closed. PMID- 29191440 TI - Predictors of linkage to HIV care and viral suppression after release from jails and prisons: a retrospective cohort study. AB - BACKGROUND: Incarceration provides an opportunity for engagement in HIV care but is associated with poor HIV treatment outcomes after release. We aimed to assess post-release linkage to HIV care (LTC) and the effect of transitional case management services. METHODS: To create a retrospective cohort of all adults with HIV released from jails and prisons in Connecticut, USA (2007-14), we linked administrative custody and pharmacy databases with mandatory HIV/AIDS surveillance monitoring and case management data. We examined time to LTC (defined as first viral load measurement after release) and viral suppression at LTC. We used generalised estimating equations to show predictors of LTC within 14 days and 30 days of release. FINDINGS: Among 3302 incarceration periods for 1350 individuals between 2007 and 2014, 672 (21%) of 3181 periods had LTC within 14 days of release, 1042 (34%) of 3064 had LTC within 30 days of release, and 301 (29%) of 1042 had detectable viral loads at LTC. Factors positively associated with LTC within 14 days of release are intermediate (31-364 days) incarceration duration (adjusted odds ratio 1.52; 95% CI 1.19-1.95), and transitional case management (1.65; 1.36-1.99), receipt of antiretroviral therapy during incarceration (1.39; 1.11-1.74), and two or more medical comorbidities (1.86; 1.48-2.36). Reincarceration (0.70; 0.56-0.88) and conditional release (0.62; 0.50 0.78) were negatively associated with LTC within 14 days. Hispanic ethnicity, bonded release, and psychiatric comorbidity were also associated with LTC within 30 days but reincarceration was not. INTERPRETATION: LTC after release is suboptimal but improves when inmates' medical, psychiatric, and case management needs are identified and addressed before release. People who are rapidly cycling through jail facilities are particularly vulnerable to missed linkage opportunities. The use of integrated programmes to align justice and health-care goals has great potential to improve long-term HIV treatment outcomes. FUNDING: US National Institutes of Health. PMID- 29191442 TI - Adding Patella Resurfacing After Circumpatellar Electrocautery Did Not Improve the Clinical Outcome in Bilateral Total Knee Arthroplasty in Chinese Population: A Prospective Randomized Study. AB - BACKGROUND: In total knee arthroplasty (TKA), handling of the patella surface is still quite controversial. We carried out a prospective randomized study to compare circumpatellar electrocautery plus patella resurfacing vs circumpatellar electrocautery only in the single-staged bilateral TKA in Chinese population. METHODS: One hundred five patients diagnosed with late-staged osteoarthritis who received single-staged bilateral TKA were screened and 53 patients were included. All patients received the same posterior cruciate-stabilizing total knee prostheses. Patients were randomized to receive circumpatellar electrocautery plus patellar resurfacing or circumpatellar electrocautery only for the first TKA, and the second knee received the opposite treatment. All patients were followed for a minimum of 2 years. RESULTS: No differences were found with regard to Knee Society Score, Feller score, anterior knee pain, and revision rates. Fifty-two percent of patients had no preference with regard to pain and function, 27% of patients preferred the resurfacing plus circumpatellar electrocautery knee while 21% of the patients preferred the circumpatellar electrocautery only knee. The Insall-Salvati index and the patella tilt were a little smaller in the resurfacing group. One patient (2.1%) in the circumpatellar electrocautery group underwent a patella resurfacing revision for severe anterior knee pain and patella subluxation. CONCLUSION: Equivalent clinical results for circumpatellar electrocautery plus resurfacing and circumpatellar electrocautery alone of the patella in TKA were demonstrated in selective Chinese population with thick enough patella. PMID- 29191443 TI - A Meta-Analysis of Patellar Replacement in Total Knee Arthroplasty for Patients With Knee Osteoarthritis. AB - BACKGROUND: This meta-analysis (MA) aims at comparing the clinical outcomes of resurfacing and nonresurfacing the patella in patients undergoing total knee arthroplasty in the treatment of knee osteoarthritis. METHODS: Randomized controlled trials were included by retrieving data from electronic English databases. Both fixed and random-effects models were employed, and standardized mean difference and 95% confidence intervals were calculated. Stata13.1 software was used for statistical analysis for all the studies included to compare the differences in improving Knee Society Clinical Score and Knee Society Function Score as well as the reduction in rates of infection, reoperation, and anterior knee pain. RESULTS: A total of 394 studies were initially included in this MA. About 20 randomized controlled trials which met the inclusion criteria were finally enrolled in this MA. The results of our MA showed that the reoperation rate of the patellar resurfacing group was lower than that of the nonresurfacing group. The subgroup analysis was performed according to the follow-up time and revealed that the increase in the Knee Society Clinical Score was higher in the patellar resurfacing group than that in the nonresurfacing group in the follow-up period of 1 to 2 years. The risk of reoperation rate was lower in the patellar resurfacing group than that in the nonresurfacing group, while there were no statistical differences in the follow-up time over 2 years. CONCLUSION: Our study suggests that during the follow-up of 1 to 2 years, patellar resurfacing can significantly increase the Knee Society Clinical Score and reduce the reoperative rates in patients with knee osteoarthritis. PMID- 29191444 TI - Implant Survival and Complication Profiles of Endoprostheses for Treating Tumor Around the Knee in Adults: A Systematic Review of the Literature Over the Past 30 Years. AB - BACKGROUND: Endoprosthetic replacement has become the mainstream method of reconstruction after tumor resection around the knee for decades, but there is a lack of comprehensive review evaluating the implant outcomes. We performed a systematic review to analyze the implant survival and complication profiles of distal femoral replacement (DFR) and proximal tibial replacement (PTR) in adults, and to evaluate the effects of different fixation methods and hinge mechanisms. METHODS: A systematic review of 40 studies with 4748 DFR cases and 1713 PTR cases was performed after searching the PubMed and EMBASE databases. Results of the implant longevity, complications, and other relevant data were extracted, recategorized, and analyzed. An additional review of 227 cases of Compress DFR from 6 studies was also performed. RESULTS: The mean 5-, 10-, 15-, and 20-year implant survival rates of DFR were 78.3%, 70.1%, 61.6%, and 38.3%, slightly higher than those of PTR (75%, 60%, 55.3%, and 25.1%). Aseptic loosening (8.8%) and infection (8.5%) were the most devastating complications in DFR, while in PTR it was infection (16.8%). Cemented or cementless fixation did not significantly affect implant survival or aseptic loosening rate. Rotating-hinge mechanism might improve long-term implant survival and reduce bushing wear, but not necessarily prevented aseptic loosening. The series Kotz modular femur and tibia replacement system/Howmedica modular replacement system/global modular replacement system was one of the most durable implants. The Compress DFR showed no superiority in implant survival and complication profiles over other brands of endoprostheses. CONCLUSION: Short-term to mid-term implant survival of adult tumor endoprostheses around the knee is acceptable but long-term outcome remains unsatisfactory. Efforts should be made in reducing loosening and infection. PMID- 29191446 TI - The efficiency of database searches for creating systematic reviews was improved by search filters. AB - OBJECTIVES: To compare Clinical Queries (CQs) for randomized trials of therapy 'methods' and 'NOT' limits search filters with Cochrane methods filters. STUDY DESIGN AND SETTING: Analytic survey of Cochrane reviews as the reference standard for retrieving studies included in the reviews ("included studies [ISs]"). The sensitivity and precision of Cochrane content terms + Cochrane methods terms were compared in MEDLINE and Embase with Cochrane content terms + CQs maximally sensitive filter for therapy studies, without and with additional 'NOT' limits (CQ-S [CQ sensitive]; CQ-S + limits) and a balanced filter without and with additional NOT limits (CQ-B [CQ balanced]; CQ-B + limits). RESULTS: Cochrane or CQ methods terms reduced, by 64-96%, the overall retrieval of articles with minimal loss of ISs. Sensitivity was high and similar for the 4 filters. However, CQ-B + limits had the highest precision (2.64%, number needed to be read to find one eligible study [NNR] 38) followed by the CQ-B (1.05%, NNR 95), Cochrane search (0.51%, NNR 198), CQ-S + limits (0.34%, NNR 296), and CQ-S filters (0.31%, NNR 325). CONCLUSION: For systematic reviews of therapeutic interventions, the efficiency of searches in MEDLINE and Embase was better served by the CQs for therapy studies with balanced methods filter and NOT limits. PMID- 29191445 TI - Training health professionals to recruit into challenging randomized controlled trials improved confidence: the development of the QuinteT randomized controlled trial recruitment training intervention. AB - OBJECTIVES: The objective of this study was to describe and evaluate a training intervention for recruiting patients to randomized controlled trials (RCTs), particularly for those anticipated to be difficult for recruitment. STUDY DESIGN AND SETTING: One of three training workshops was offered to surgeons and one to research nurses. Self-confidence in recruitment was measured through questionnaires before and up to 3 months after training; perceived impact of training on practice was assessed after. Data were analyzed using two-sample t tests and supplemented with findings from the content analysis of free-text comments. RESULTS: Sixty-seven surgeons and 32 nurses attended. Self-confidence scores for all 10 questions increased after training [range of mean scores before 5.1-6.9 and after 6.9-8.2 (scale 0-10, all 95% confidence intervals are above 0 and all P-values <0.05)]. Awareness of hidden challenges of recruitment following training was high-surgeons' mean score 8.8 [standard deviation (SD), 1.2] and nurses' 8.4 (SD, 1.3) (scale 0-10); 50% (19/38) of surgeons and 40% (10/25) of nurses reported on a 4-point Likert scale that training had made "a lot" of difference to their RCT discussions. Analysis of free text revealed this was mostly in relation to how to convey equipoise, explain randomization, and manage treatment preferences. CONCLUSION: Surgeons and research nurses reported increased self-confidence in discussing RCTs with patients, a raised awareness of hidden challenges and a positive impact on recruitment practice following QuinteT RCT Recruitment Training. Training will be made more available and evaluated in relation to recruitment rates and informed consent. PMID- 29191447 TI - Comparative evidence on harms in pediatric randomized clinical trials from less developed versus more developed countries is limited. AB - OBJECTIVES: Evaluate comparative harm rates from medical interventions in pediatric randomized clinical trials (RCTs) from more developed (MDCs) and less developed countries (LDCs). STUDY DESIGN AND SETTING: Meta-epidemiologic empirical evaluation of Cochrane Database of Systematic Reviews (June 2014) meta analyses reporting clinically important harm-outcomes (severe adverse events [AEs], discontinuations due to AEs, any AE, and mortality) that included at least one pediatric RCT from MDCs and at least one from LDCs. We estimated relative odds ratios (RORs) for each harm, within each meta-analysis, between RCTs from MDCs and LDCs and calculated random-effects-summary-RORs (sRORs) for each harm across multiple meta-analyses. RESULTS: Only 1% (26/2,363) of meta-analyses with clinically important harm-outcomes in the entire Cochrane Database of Systematic Reviews included pediatric RCTs both from MDCs and LDCs. We analyzed 26 meta analyses with 244 data sets from pediatric RCTs, 116 from MDCs and 128 from LDCs (64 and 66 unique RCTs respectively). The summary ROR was 0.92 (95% confidence intervals: 0.78-1.08) for severe AEs; 1.13 (0.54-2.34) for discontinuations due to AEs; 1.10 (0.77-1.59) for any AE; and 0.99 (0.61-1.61) for mortality and for the all-harms-combined-end point 0.96 (0.83-1.10). Differences of ROR-point estimates >=2-fold between MDCs and LDCs were identified in 35% of meta-analyses. CONCLUSION: We found no major systematic differences in harm rates in pediatric trials between MDCs and LDCs, but data on harms in children were overall very limited. PMID- 29191448 TI - Adverse perinatal outcomes associated with crown-rump length discrepancy in in vitro fertilization pregnancies. AB - OBJECTIVE(S): To determine whether an association exists between small crown-rump length (CRL) and adverse obstetrical outcomes in pregnancies conceived by IVF and to compare a CRL reference based on IVF pregnancies to a reference based on spontaneous pregnancies. DESIGN: Retrospective cohort study. CRL was classified as small by comparing it with the local university hospital maternal fetal medicine standard and the Monash IVF reference chart. SETTING: University affiliated fertility center. PATIENT(S): Singleton pregnancies conceived by IVF with ultrasounds performed between 7+0 and 8+6 weeks of gestational age. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Pregnancy loss, preterm birth, and low birth weight. RESULT(S): Included were 940 clinical pregnancies. The overall and CRL-discrepant miscarriage rates were 12.7% and 41%, respectively. When CRL was small, the maternal age-adjusted odds of miscarriage were 13.8 times higher (95% confidence interval [CI], 8.9-21.6). At age 30, small CRL was associated with a 30% risk of miscarriage, versus 61% at age 45. There was no association between small CRL and preterm birth or low birth weight. The sensitivity and specificity for predicting miscarriage from the optimal Monash cut point were 0.69 (95% CI, 0.61-0.77) and 0.84 (95% CI, 0.82-0.87), which were similar to those of the CRL reference based on spontaneous pregnancies. CONCLUSION(S): Small CRL in IVF pregnancy was strongly associated with miscarriage, especially in the context of advanced maternal age. Small CRL was not associated with preterm birth or low birth weight. A CRL reference based on IVF pregnancies was equivalent to the standard reference for predicting miscarriage. PMID- 29191449 TI - Extent of chromosomal mosaicism influences the clinical outcome of in vitro fertilization treatments. AB - OBJECTIVE: To assess whether the extent of chromosomal mosaicism can influence the success rate of IVF treatments. DESIGN: Prospective study. SETTING: Private genetic and assisted reproduction centers. PATIENT(S): The transfer of mosaic embryos was offered to 77 women for which IVF resulted in no euploid embryos available for transfer. INTERVENTION(S): All embryos were cultured to blastocyst stage; trophectoderm biopsy was performed on day 5/6 of development. Comprehensive chromosome screening was performed using either next-generation sequencing or array-comparative genomic hybridization methodologies. MAIN OUTCOME MEASURE(S): The clinical outcome obtained after transfer of mosaic embryos with low (<50%) and high (>=50%) aneuploidy percentage was compared with that resulting from a control group of 251 euploid blastocysts. RESULT(S): A significantly higher implantation rate (48.9% vs. 24.2%), clinical pregnancy rate/ET (40.9% vs. 15.2%), and live-birth rate (42.2% vs. 15.2%) were observed comparing embryos with mosaicism <50% and >=50%. Mosaic embryos with high aneuploidy percentage (>=50%) showed a significantly lower clinical pregnancy rate/ET (15.2% vs. 46.4%), implantation rate (24.4% vs. 54.6%), and live-birth rate (15.2% vs. 46.6%) than euploid blastocysts. In contrast, embryos with lower aneuploidy percentage (<50%) have a clinical outcome similar to euploid embryos. CONCLUSION(S): The results of this study further confirm that mosaic embryos can develop into healthy euploid newborns. We demonstrated that the extent of mosaicism influences the IVF success rate. Mosaic embryos with low aneuploidy percentage have higher chances of resulting in the birth of healthy babies compared with embryos with higher mosaicism levels. PMID- 29191450 TI - Comparative Bioavailability of Hydroxyprogesterone Caproate Administered via Intramuscular Injection or Subcutaneous Autoinjector in Healthy Postmenopausal Women: A Randomized, Parallel Group, Open-label Study. AB - PURPOSE: The purpose of this study was to evaluate the bioavailability of hydroxyprogesterone caproate (HPC) administered as a subcutaneous injection in the back of the upper arm using a prefilled autoinjector syringe with a 27-gauge needle compared with standard intramuscular injection in the gluteus maximus using a 21-gauge needle. METHODS: Healthy postmenopausal women 50 to 75 years old were randomized in a parallel group design to receive a single SC injection of 1.1 mL (275-mg total dose) of preservative-free HPC administered using an autoinjector in the back of the upper arm or a single IM injection of 1 mL (250 mg total dose) of preservative-free HPC administered in the gluteus maximus. Blood samples were collected through 1008 hours (42 days) after injection. The primary measures were the Cmax, AUC0-t, and AUC0-infinity. Secondary measures were Tmax, ke, t1/2, and injection site reactions captured as a treatment emergent adverse event. FINDINGS: The pharmacokinetic population consisted of 90 individuals; 45 received subcutaneous administration and 45 received intramuscular administration. Geometric mean whole blood concentrations of HPC were comparable between administration regimens. Subcutaneous administration resulted in a higher geometric mean Cmax than intramuscular administration (7.88 vs 6.91 ng/mL), but median Tmax values were comparable (48.1 vs 49.7 hours). The least square geometric mean ratios for AUC0-168), AUC0-t, and AUC0-infinity were 102.89%, 110.25%, and 113.51%, respectively, with all 90% CIs within the 80.0% to 125.0% window that defined bioequivalence. The ratio for Cmax was 113.95% with a 90% CI of 91.94% to 141.23% but with substantial overlap of individual values between administration regimens. The geometric mean t1/2 of HPC was 212 hours for the subcutaneous administration and 188 hours for the intramuscular administration. The most common treatment-emergent adverse event was injection site pain (subcutaneous, 37.3%; intramuscular, 8.2%), described as mild (85%) to moderate (15%). IMPLICATIONS: Administration of HPC by SC injection of 1.1 mL (275 mg) via autoinjector is bioequivalent to IM injection of 1.0 mL (250 mg). ClinicalTrials.gov identifier: NCT02940522.

AB - cis-Diamminedichloroplatinum (cisplatin) is an effective chemotherapeutic and is widely used for the treatment of various types of solid tumors. Bio-distribution of cisplatin to other organs due to poor targeting towards only cancer cells constitutes the backbone of cisplatin-induced toxicity. The adverse effect of this drug on spleen is not well characterized so far. Therefore, we have set our goal to explore the mechanism of the cisplatin-induced pathophysiology of the spleen and would also like to evaluate whether carnosine, an endogenous neurotransmitter and antioxidant, can ameliorate this pathophysiological response. We found a dose and time-dependent increase of the pro-inflammatory cytokine, TNF-alpha, in the spleen tissue of the experimental mice exposed to 10 and 20 mg/kg body weight of cisplatin. The increase in inflammatory cytokine can be attributed to the activation of the transcription factor, NF-KB. This also aids in the transcription of other pro-inflammatory cytokines and cellular adhesion molecules. Exposure of animals to cisplatin at both the doses resulted in ROS and NO production leading to oxidative stress. The MAP Kinase pathway, especially JNK activation, was also triggered by cisplatin. Eventually, the persistence of inflammatory response and oxidative stress lead to apoptosis through extrinsic pathway. Carnosine has been found to restore the expression of inflammatory molecules and catalase to normal levels through inhibition of pro inflammatory cytokines, oxidative stress, NF-KB and JNK. Carnosine also protected the splenic cells from apoptosis. Our study elucidated the detailed mechanism of cisplatin-induced spleen toxicity and use of carnosine as a protective agent against this cytotoxic response.

AB - This study has evaluated the action of flavonoid hesperidin on the neurotoxic effects caused by the intake of iron (Fe) in Drosophila melanogaster. Male adult flies, aged 1-3 days, have been divided into four groups of 50 each: (1) control, (2) Hsd 10 MUM, (3) Fe 20 mM (4) Hsd 10 MUM + Fe 20 mM. During the exposure protocol, the flies have been exposed to a diet containing Hsd and/or Fe for 48 h. The survival and behavioral analyses have been carried out in vivo, and ex vivo. The analyses involved acetylcholinesterase (AChE) activity and Fe levels in the flies' heads and bodies and determination of dopaminergic levels, cellular and mitochondrial viability, activities of superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST), reactive species levels (RS), thiobarbituric acid reactive substances (TBARS) and contents of total thiols and non-proteic thiols (NPSH) in the flies' heads. A significant negative correlation between Fe levels in the head of the flies and the survival, dopamine levels and antioxidant enzymes in the head of the flies has been found. Additionally, significant positive correlation between Fe levels in the head of the flies with negative geotaxis RS and AChE activity in the head of the flies has been found. It demonstrates that the flies which had higher levels of Fe in their heads have demonstrated more susceptibility to neurotoxicity. An important result from our study is that Hsd treatment promotes a decrease in Fe concentration in the head, restores dopamine levels and cholinergic activity of the flies and improves motor function caused by Fe. Hsd also ameliorates Fe induced mortality, oxidative stress and mitochondrial dysfunction. Our results have demonstrated the neuroprotective effect of Hsd and it suggests that flavonoid acts in different ways to protect against the Parkinson disease caused by Fe exposure such as the direct scavenging of RS and activation of antioxidant enzymes.

AB - Chemo-resistance is a serious obstacle for successful treatment of cancer. Apigenin, a dietary flavonoid, has been reported as an anticancer drug in various malignant cancers. This study aimed to investigate the potential chemo sensitization effect of apigenin in doxorubicin-resistant hepatocellular carcinoma cell line BEL-7402/ADM. We observed that apigenin significantly enhanced doxorubicin sensitivity, induced miR-520b expression and inhibited ATG7 dependent autophagy in BEL-7402/ADM cells. In addition, we also showed that miR 520b mimics increased doxorubicin sensitivity and inhibited ATG7-dependent autophagy. Meanwhile, we indicated that ATG7 was a potential target of miR-520b. Furthermore, APG inhibited the growth of hepatocellar carcinoma xenografts in nude mice by up-regulating miR-520b and inhibiting ATG7. Our finding provides evidence that apigenin sensitizes BEL-7402/ADM cells to doxorubicin through miR 520b/ATG7 pathway, which furtherly supports apigenin as a potential chemo sensitizer for hepatocellular carcinoma. PMID- 29191454 TI - Fullerene (C60) particle size implications in neurotoxicity following infusion into the hippocampi of Wistar rats. AB - The buckminsterfullerene (C60) is considered as a relevant candidate for drug and gene delivery to the brain, once it has the ability to cross the blood-brain barrier. However, the biological implications of this nanomaterial are not fully understood, and its safety for intracerebral delivery is still debatable. In this study, we investigated if C60 particle size could alter its biological effects. For this, two aqueous C60 suspensions were used with maximum particle size up to 200nm and 450nm. The suspensions were injected in the hippocampus, the main brain structure involved in memory processing and spatial localization. In order to assess spatial learning, male Wistar rats were tested in Morris water maze, and the hippocampal BDNF protein levels and gene expression were analyzed. Animals treated with C60 up to 450nm demonstrated impaired spatial memory with a significant decrease in BDNF protein levels and gene expression. However, an enhanced antioxidant capacity was observed in both C60 treatments. A decrease in reactive oxygen species levels was observed in the treatments with suspensions containing particles measuring with up to 450nm. Thiobarbituric acid reactive substances, glutamate cysteine ligase, and glutathione levels showed no alterations among the different treatments. In conclusion, different particle sizes of the same nanomaterial can lead to different behavioral outcomes and biochemical parameters in brain tissue.

PMID- 29191456 TI - Impact of systemic inflammation on the relationship between insulin resistance and all-cause and cancer-related mortality. AB - BACKGROUND: Insulin resistance and inflammation play an important role in a variety of chronic diseases. OBJECTIVE: We investigated the influence of systemic inflammation on the relationship between insulin resistance and mortality risk in apparently healthy adults. METHODS: This study examined the mortality outcomes for 165,849 Koreans enrolled in a health-screening program. The subjects were divided into four groups according to their homeostatic model assessment of insulin resistance (HOMA-IR) and high-sensitivity C-reactive protein (hs-CRP) levels: group 0, HOMA-IR <75% and hs-CRP <2.0mg/L; group 1, HOMA-IR >=75% and hs CRP <2.0mg/L; group 2, HOMA-IR <75% and hs-CRP >=2.0mg/L; and group 3, HOMA-IR >=75% and hs-CRP >=2.0mg/L. The Cox proportional hazard models were used to assess hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause, cardiovascular disease, and cancer-related mortality. RESULTS: During the follow up period of 1,417,325.6person-years, a total of 1316 deaths (182 from cardiovascular disease) occurred. The multivariate-adjusted HRs for all-cause mortality were significantly higher in groups 2 (HR 1.40; 95% CI: 1.19-1.64) and group 3 (HR 1.68; 95% CI: 1.34-2.10) than that in group 0. For cardiovascular mortality, the sex-adjusted hazards were also significantly higher in groups 2 and 3 than that in group 0; however, this increased risk disappeared during multivariate analysis. Groups 2 and 3 had significantly higher risk for cancer related mortality than group 0, with multivariate-adjusted hazard ratios of 1.48 (95% CI: 1.18-1.86) and 1.84 (95% CI: 1.35-2.51), respectively. CONCLUSIONS: Systemic inflammation can be used to stratify the subjects according to the all cause and cancer-related mortality risks, irrespective of the insulin-resistance status. And this tendency is most pronounced in cancer-related mortality. PMID- 29191457 TI - The physics of small megavoltage photon beam dosimetry. AB - The increased interest during recent years in the use of small megavoltage photon beams in advanced radiotherapy techniques has led to the development of dosimetry recommendations by different national and international organizations. Their requirement of data suitable for the different clinical options available, regarding treatment units and dosimetry equipment, has generated a considerable amount of research by the scientific community during the last decade. The multiple publications in the field have led not only to the availability of new invaluable data, but have also contributed substantially to an improved understanding of the physics of their dosimetry. This work provides an overview of the most important aspects that govern the physics of small megavoltage photon beam dosimetry. PMID- 29191458 TI - Long term radiological features of radiation-induced lung damage. AB - PURPOSE: To describe the radiological findings of radiation-induced lung damage (RILD) present on CT imaging of lung cancer patients 12 months after radical chemoradiation. MATERIAL AND METHODS: Baseline and 12-month CT scans of 33 patients were reviewed from a phase I/II clinical trial of isotoxic chemoradiation (IDEAL CRT). CT findings were scored in three categories derived from eleven sub-categories: (1) parenchymal change, defined as the presence of consolidation, ground-glass opacities (GGOs), traction bronchiectasis and/or reticulation; (2) lung volume reduction, identified through reduction in lung height and/or distortions in fissures, diaphragm, anterior junction line and major airways anatomy, and (3) pleural changes, either thickening and/or effusion. RESULTS: Six patients were excluded from the analysis due to anatomical changes caused by partial lung collapse and abscess. All remaining 27 patients had radiological evidence of lung damage. The three categories, parenchymal change, shrinkage and pleural change were present in 100%, 96% and 82% respectively. All patients had at least two categories of change present and 72% all three. GGOs, reticulation and traction bronchiectasis were present in 44%, 52% and 37% of patients. CONCLUSIONS: Parenchymal change, lung shrinkage and pleural change are present in a high proportion of patients and are frequently identified in RILD. GGOs, reticulation and traction bronchiectasis are common at 12 months but not diagnostic. PMID- 29191459 TI - Impact of real-time metabolomics in liver transplantation: Graft evaluation and donor-recipient matching. AB - BACKGROUND & AIMS: There is an emerging need to assess the metabolic state of liver allografts especially in the novel setting of machine perfusion preservation and donor in cardiac death (DCD) grafts. High-resolution magic-angle spinning nuclear magnetic resonance (HR-MAS-NMR) could be a useful tool in this setting as it can extemporaneously provide untargeted metabolic profiling. The purpose of this study was to evaluate the potential value of HR-MAS-NMR metabolomic analysis of back-table biopsies for the prediction of early allograft dysfunction (EAD) and donor-recipient matching. METHOD: The metabolic profiles of back-table biopsies obtained by HR-MAS-NMR, were compared according to the presence of EAD using partial least squares discriminant analysis. Network analysis was used to identify metabolites which changed significantly. The profiles were compared to native livers to identify metabolites for donor recipient matching. RESULTS: The metabolic profiles were significantly different in grafts that caused EAD compared to those that did not. The constructed model can be used to predict the graft outcome with excellent accuracy. The metabolites showing the most significant differences were lactate level >8.3 mmol/g and phosphocholine content >0.646 mmol/g, which were significantly associated with graft dysfunction with an excellent accuracy (AUROClactates = 0.906; AUROCphosphocholine = 0.816). Native livers from patients with sarcopenia had low lactate and glycerophosphocholine content. In patients with sarcopenia, the risk of EAD was significantly higher when transplanting a graft with a high-risk graft metabolic score. CONCLUSION: This study underlines the cost of metabolic adaptation, identifying lactate and choline-derived metabolites as predictors of poor graft function in both native livers and liver grafts. HR-MAS-NMR seems a valid technique to evaluate graft quality and the consequences of cold ischemia on the graft. It could be used to assess the efficiency of graft resuscitation on machine perfusion in future studies. LAY SUMMARY: Real-time metabolomic profiles of human grafts during back-table can accurately predict graft dysfunction. High lactate and phosphocholine content are highly predictive of graft dysfunction whereas low lactate and phosphocholine content characterize patients with sarcopenia. In these patients, the cost of metabolic adaptation may explain the poor outcomes. PMID- 29191460 TI - The mitochondrial 2-oxoadipate and 2-oxoglutarate dehydrogenase complexes share their E2 and E3 components for their function and both generate reactive oxygen species. AB - Herein are reported unique properties of the novel human thiamin diphosphate (ThDP)-dependent enzyme 2-oxoadipate dehydrogenase (hE1a), known as dehydrogenase E1 and transketolase domain-containing protein 1 that is encoded by the DHTKD1 gene. It is involved in the oxidative decarboxylation of 2-oxoadipate (OA) to glutaryl-CoA on the final degradative pathway of L-lysine and is critical for mitochondrial metabolism. Functionally active recombinant hE1a has been produced according to both kinetic and spectroscopic criteria in our toolbox leading to the following conclusions: (i) The hE1a has recruited the dihydrolipoyl succinyltransferase (hE2o) and the dihydrolipoyl dehydrogenase (hE3) components of the tricarboxylic acid cycle 2-oxoglutarate dehydrogenase complex (OGDHc) for its activity. (ii) 2-Oxoglutarate (OG) and 2-oxoadipate (OA) could be oxidized by hE1a, however, hE1a displays an approximately 49-fold preference in catalytic efficiency for OA over OG, indicating that hE1a is specific to the 2-oxoadipate dehydrogenase complex. (iii) The hE1a forms the ThDP-enamine radical from OA according to electron paramagnetic resonance detection in the oxidative half reaction, and could produce superoxide and H2O2 from decarboxylation of OA in the forward physiological direction, as also seen with the 2-oxoglutarate dehydrogenase hE1o component. (iv) Once assembled to complex with the same hE2o and hE3 components, the hE1o and hE1a display strikingly different regulation: both succinyl-CoA and glutaryl-CoA significantly reduced the hE1o activity, but not the activity of hE1a. PMID- 29191461 TI - Endoplasmic reticulum stress precedes oxidative stress in antibiotic-induced cholestasis and cytotoxicity in human hepatocytes. AB - Endoplasmic reticulum (ER) stress has been associated with various drug-induced liver lesions but its participation in drug-induced cholestasis remains unclear. We first aimed at analyzing liver damage caused by various hepatotoxic antibiotics, including three penicillinase-resistant antibiotics (PRAs), i.e. flucloxacillin, cloxacillin and nafcillin, as well as trovafloxacin, levofloxacin and erythromycin, using human differentiated HepaRG cells and primary hepatocytes. All these antibiotics caused early cholestatic effects typified by bile canaliculi dilatation and reduced bile acid efflux within 2h and dose dependent enhanced caspase-3 activity within 24h. PRAs induced the highest cholestatic effects at non cytotoxic concentrations. Then, molecular events involved in these lesions were analyzed. Early accumulation of misfolded proteins revealed by thioflavin-T fluorescence and associated with phosphorylation of the unfolded protein response sensors, eIF2alpha and/or IRE1alpha, was evidenced with all tested hepatotoxic antibiotics. Inhibition of ER stress markedly restored bile acid efflux and prevented bile canaliculi dilatation. Downstream of ER stress, ROS were also generated with high antibiotic concentrations. The protective HSP27-PI3K-AKT signaling pathway was activated only in PRA-treated cells and its inhibition increased ROS production and aggravated caspase-3 activity. Overall, our results demonstrate that (i) various antibiotics reported to cause cholestasis and hepatocellular injury in the clinic can also induce such effects in in vitro human hepatocytes; (ii) PRAs cause the strongest cholestatic effects in the absence of cytotoxicity; (iii) cholestatic features occur early through ER stress; (iv) cytotoxic lesions are observed later through ER stress mediated ROS generation; and (v) activation of the HSP27-PI3K-AKT pathway protects from cytotoxic damage induced by PRAs only. PMID- 29191462 TI - Exposure of tropoelastin to peroxynitrous acid gives high yields of nitrated tyrosine residues, di-tyrosine cross-links and altered protein structure and function. AB - Elastin is an abundant extracellular matrix protein in elastic tissues, including the lungs, skin and arteries, and comprises 30-57% of the aorta by dry mass. The monomeric precursor, tropoelastin (TE), undergoes complex processing during elastogenesis to form mature elastic fibres. Peroxynitrous acid (ONOOH), a potent oxidising and nitrating agent, is formed in vivo from superoxide and nitric oxide radicals. Considerable evidence supports ONOOH formation in the inflamed artery wall, and a role for this species in the development of human atherosclerotic lesions, with ONOOH-damaged extracellular matrix implicated in lesion rupture. We demonstrate that TE is highly sensitive to ONOOH, with this resulting in extensive dimerization, fragmentation and nitration of Tyr residues to give 3 nitrotyrosine (3-nitroTyr). This occurs with equimolar or greater levels of oxidant and increases in a dose-dependent manner. Quantification of Tyr loss and 3-nitroTyr formation indicates extensive Tyr modification with up to two modified Tyr per protein molecule, and up to 8% conversion of initial ONOOH to 3-nitroTyr. These effects were modulated by bicarbonate, an alternative target for ONOOH. Inter- and intra-protein di-tyrosine cross-links have been characterized by mass spectrometry. Examination of human atherosclerotic lesions shows colocalization of 3-nitroTyr with elastin epitopes, consistent with TE or elastin modification in vivo, and also an association of 3-nitroTyr containing proteins and elastin with lipid deposits. These data suggest that exposure of TE to ONOOH gives marked chemical and structural changes to TE and altered matrix assembly, and that such damage accumulates in human arterial tissue during the development of atherosclerosis. PMID- 29191463 TI - Raphe Pallidus is Not Important to Central Chemoreception in a Rat Model of Parkinson's Disease. AB - Central chemoreceptors are primarily sensitive to changes in CO2/H+, and such changes lead to intense breathing activity. Medullary raphe and retrotrapezoid nucleus (RTN) neurons are candidates for central chemoreceptors because they are unusually pH sensitive. The pathophysiology of Parkinson's disease (PD) is related to the reduction of neurons in the substantia nigra pars compacta (SNpc) that express dopamine, although other neurons can also be degenerated in this pathology. In rodent models of PD, we showed an impairment of the hypercapnia ventilatory response due to a reduction in the number of RTN chemosensitive neurons. Here, we aimed to investigate if serotonine-expressing neurons in the Raphe pallidus/parapyramidal region (RPa/PPy) are also involved in the modulation of breathing during central chemoreception activation in a PD animal model. PD was induced in male Wistar rats with bilateral injection of 6-OHDA (6 hydroxydopamine; 24 ug/ul) into the striatum, which leads to a reduction in the catecholaminergic neurons of the SNpc by 89%. In PD animals, we noticed a reduction in the number of RPa neurons that project to the RTN, without a change in the number of hypercapnia-activated (7% CO2) raphe neurons. The PD animals that received injection of the toxin saporin anti-SERT into the RPA/PPy region did not show a further reduction of respiratory frequency (fR) or ventilation (VE) at rest or during hypercapnia challenge. These experiments demonstrate that serotonergic neurons of RPa/PPy are not involved in the breathing responses induced by central chemoreceptor activation in a PD animal model. PMID- 29191464 TI - Bombyx ortholog of the Drosophila eye color gene brown controls riboflavin transport in Malpighian tubules. AB - The Drosophila eye color gene brown is known to control the transport of pteridine precursors in adult eyes. The Brown protein belongs to the ATP-binding cassette (ABC) transporter G family, which includes proteins encoded by the genes brown, scarlet, and white. These genes are responsible for pigmentation in Drosophila and the domestic silkworm Bombyx mori. Although orthologs of brown are conserved among insects, the function of this gene is only known in Drosophila. Here, we elucidated the function of the B. mori ortholog Bm-brown. We examined the spatial and temporal expression profiles of Bm-brown and found that this gene was specifically and continuously expressed in larval Malpighian tubules (MTs), indicating this gene has a special function in MTs. We then successfully obtained a Bm-brown knockout (KO) strain based on a wild-type (WT) strain using the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR associated nuclease 9 (Cas9) system. We found that larval MTs of the KO strain were white, whereas those of WT were yellow. It is known that larval yellow MTs of WT are due to the accumulation of riboflavin. Therefore, we compared the riboflavin contents of MTs of KO and WT strains, and found that the riboflavin level in the KO strain was 20 fold less than that in WT during the 5th instar period. MTs are known to exhibit a similar milky color in w-3 mutant larvae due to a deficiency of riboflavin accumulation. The responsible gene for w-3 mutant is the Bmwh3 gene, which is orthologous to Drosophila white. Thus, we speculate that Bm-brown is heterodimerized with Bmwh3, similar to Brown/White in Drosophila, and acts as a riboflavin transporter in silkworm MTs. PMID- 29191465 TI - Crystal structure of ryanodine receptor N-terminal domain from Plutella xylostella reveals two potential species-specific insecticide-targeting sites. AB - Ryanodine receptors (RyRs) are large calcium-release channels located in sarcoplasmic reticulum membrane. They play a central role in excitation contraction coupling of muscle cells. Three commercialized insecticides targeting pest RyRs generate worldwide sales over 2 billion U.S. dollars annually, but the structure of insect RyRs remains elusive, hindering our understanding of the mode of action of RyR-targeting insecticides and the development of insecticide resistance in pests. Here we present the crystal structure of RyR N-terminal domain (NTD) (residue 1-205) at 2.84 A resolution from the diamondback moth (DBM), Plutella xylostella, a destructive pest devouring cruciferous crops all over the world. Similar to its mammalian homolog, DBM RyR NTD consists of a beta trefoil folding motif and a flanking alpha helix. Interestingly, two regions in NTD interacting with neighboring domains showed distinguished conformations in DBM relative to mammalian RyRs. Using homology modeling and molecular dynamics simulation, we created a structural model of the N-terminal three domains, showing two unique binding pockets that could be targeted by potential species specific insecticides. Thermal melt experiment showed that the stability of DBM RyR NTD was higher than mammalian RyRs, probably due to a stable intra-domain disulfide bond observed in the crystal structure. Previously DBM NTD was shown to be one of the two critical regions to interact with insecticide flubendiamide, but isothermal titration calorimetry experiments negated DBM NTD alone as a major binding site for flubendiamide. PMID- 29191466 TI - Synovial fluid multiplex PCR is superior to culture for detection of low-virulent pathogens causing periprosthetic joint infection. AB - INTRODUCTION: Analysis of joint aspirate is the standard preoperative investigation for diagnosis of periprosthetic joint infection (PJI). We compared the diagnostic performance of culture and multiplex polymerase chain reaction (PCR) of synovial fluid for diagnosis of PJI. PATIENTS AND METHODS: Patients in whom aspiration of the prosthetic hip or knee joint was performed before revision arthroplasty were prospectively included. The performance of synovial fluid culture and multiplex PCR was compared by McNemar's chi-squared test. RESULTS: A total of 142 patients were included, 82 with knee and 60 with hip prosthesis. PJI was diagnosed in 77 patients (54%) and aseptic failure in 65 patients (46%). The sensitivity of synovial fluid culture and PCR was 52% and 60%, respectively, showing concordant results in 116 patients (82%). In patients with PJI, PCR missed 6 high-virulent pathogens (S. aureus, streptococci, E. faecalis, E. coli) which grew in synovial fluid culture, whereas synovial fluid culture missed 12 pathogens detected by multiplex PCR, predominantly low-virulent pathogens (Cutibacterium acnes and coagulase-negative staphylococci). In patients with aseptic failure, PCR detected 6 low-virulent organisms (predominantly C. acnes). CONCLUSION: While the overall performance of synovial fluid PCR was comparable to culture, PCR was superior for detection of low-virulent bacteria such as Cutibacterium spp. and coagulase-negative staphylococci. In addition, synovial fluid culture required several days for growth, whereas multiplex PCR provided results within 5hours in an automated manner.

PMID- 29191468 TI - Malunion of post-traumatic thoracolumbar fractures. AB - Thoracolumbar malunion is the result of loss of correction, insufficient correction or even no correction (both in the frontal and sagittal planes) of a thoracolumbar fracture. The main causes are incorrect assessment of the fracture's complexity (burst fracture), its potential progression to kyphosis and associated disc or ligament damage. It can also be the result of a poorly conducted initial treatment. The types of malunion have changed over the years because of the introduction of vertebroplasty and kyphoplasty. The malunion can be well tolerated if there is only a moderate deformity. However, the functional and pain-related limitations can be severe with large deformities. Functional limitation is mainly related to sagittal imbalance, but also to sequelae associated with the injury in various ways (non-union, disc degeneration, spinal cord compression, syringomyelia, etc.). The deformity and its consequences are evaluated globally using full-body standing radiographs (EOS), CT scan and MRI. Comparison of MRI images taken in a lying position to weight bearing views or even dynamic ones is an additional means to evaluate whether the lesions are reducible. Differences in spine morphology and compensatory mechanisms to combat the sagittal imbalance induced by the deformity must also be analyzed. These provide more complete information about the consequences of the malunion and help to establish the best corrective strategy. These compensatory mechanisms consist of accentuation of lumbar lordosis along with reduction of thoracic kyphosis. As a last resort, the pelvis and femur contribute to this compensation when there is a large deformity or a stiff spine due to preexisting osteoarthritis. Treatment strategies are fairly well standardized. When the deformity is reducible, a two stage surgery is indicated. When the deformity is not reducible, posterior transpedicular closed wedge osteotomy is the gold standard. Nevertheless, the best way to treat thoracolumbar malunion is to prevent it. PMID- 29191469 TI - Role of anterolateral reconstruction in patients undergoing anterior cruciate ligament reconstruction. AB - There is renewed interest in anterolateral reconstruction (ALR) for patients undergoing anterior cruciate ligament (ACL) reconstruction. This is the result of isolated ACL reconstruction and double-bundle reconstruction providing inadequate control over the pivot shift, and recent anatomical and biomechanical studies on the anterolateral ligament (ALL) and its role in the knee's rotational stability. From a technical point of view, ALR can be performed either as a continuity of the intra-articular ACL reconstruction or an independent procedure. The typical peripheral grafts (gracilis and semitendinosus tendons, iliotibial band) can be used. The femoral tunnel must be posterior and proximal to the lateral epicondyle, and the tibial tunnel on a line joining Gerdy's tubercle with the ALL's tibial insertion. Tensioning and fixation are done with the knee near full extension and the tibia in neutral rotation. The ALR complication rate reported in older studies (pain, hematoma, scar damage) has been reduced. Relative to isolated ACL reconstruction, ALR does not alter the infection or stiffness rate, and it reduces the re-injury rate and secondary meniscal damage rate. Analysis of the literature has not shown an increased rate of osteoarthritis after ALR. The objective and functional outcomes are equal to those after isolated ACL reconstruction. Control over rotation is improved by adding ALR and the return to pivot sports appears to be more successful. While the indications must still be refined, ALR can be proposed to young patients undergoing ACL reconstruction who participate in high-intensity pivot sports, have a high-grade pivot shift or who have a failed ACL reconstruction. PMID- 29191470 TI - Optimal beam margins in linac-based VMAT stereotactic ablative body radiotherapy: a Pareto front analysis for liver metastases. AB - We explored the Pareto fronts mathematical strategy to determine the optimal block margin and prescription isodose for stereotactic body radiotherapy (SBRT) treatments of liver metastases using the volumetric-modulated arc therapy (VMAT) technique. Three targets (planning target volumes [PTVs] = 20, 55, and 101 cc) were selected. A single fraction dose of 26 Gy was prescribed (prescription dose [PD]). VMAT plans were generated for 3 different beam energies. Pareto fronts based on (1) different multileaf collimator (MLC) block margin around PTV and (2) different prescription isodose lines (IDL) were produced. For each block margin, the greatest IDL fulfilling the criteria (95% of PTV reached 100%) was considered as providing the optimal clinical plan for PTV coverage. Liver Dmean, V7Gy, and V12Gy were used against the PTV coverage to generate the fronts. Gradient indexes (GI and mGI), homogeneity index (HI), and healthy liver irradiation in terms of Dmean, V7Gy, and V12Gy were calculated to compare different plans. In addition, each target was also optimized with a full-inverse planning engine to obtain a direct comparison with anatomy-based treatment planning system (TPS) results. About 900 plans were calculated to generate the fronts. GI and mGI show a U shaped behavior as a function of beam margin with minimal values obtained with a +1 mm MLC margin. For these plans, the IDL ranges from 74% to 86%. GI and mGI show also a V-shaped behavior with respect to HI index, with minimum values at 1 mm for all metrics, independent of tumor dimensions and beam energy. Full inversed optimized plans reported worse results with respect to Pareto plans. In conclusion, Pareto fronts provide a rigorous strategy to choose clinical optimal plans in SBRT treatments. We show that a 1-mm MLC block margin provides the best results with regard to healthy liver tissue irradiation and steepness of dose fallout. PMID- 29191471 TI - Nerve-Sparing Approach Improves Outcomes of Patients Undergoing Minimally Invasive Radical Hysterectomy: A Systematic Review and Meta-Analysis. AB - Few studies have investigated the efficacy and safety of the nerve-sparing approach via minimally invasive surgery for the treatment of cervical cancer. We aimed to review the current evidence comparing nerve-sparing minimally invasive radical hysterectomy (NS-MRH) with conventional minimally invasive radical hysterectomy (MRH). This systematic review was registered in the International Prospective Register of Systematic Reviews (CRD#57655). Overall, 675 patients were included: 350 (51.9%) and 325 (48.1%) patients undergoing MRH and NS-MRH, respectively. MRH was associated with a shorter operative time in comparison with NS-MRH (mean difference = 32.57 minutes; 95% CI, 22.87-42.48). The estimated blood loss (mean difference = 97.14 mL, 20.01-214.29) and transfusion rate (odds ratio [OR] = 0.67; 95% confidence interval [CI], 0.15-3.01) did not differ statistically between the 2 groups. The risk of developing intraoperative (OR = 0.43; 95% CI, 0.08-2.23) and severe postoperative (OR = 0.63; 95% CI, 0.17-2.39) complications was similar between NS-MRH and MRH. Patients undergoing NS-MRH experienced lower voiding (OR = 0.39; 95% CI, 0.19-0.81) dysfunction rates than patients undergoing MRH. Moreover, a trend toward lower sexual (OR = 0.25; 95% CI, 0.06-1.07) and rectal (OR = 0.12; 95% CI, 0.01-1.02) issues was observed for patients having NS-MRH compared with patients undergoing MRH. Survival outcomes are not influenced by the type of surgical approach (recurrence [OR = 1.27; 95% CI, 0.49-3.28] and death [OR = 1.01; 95% CI, 0.36-2.83]) rates. The pooled data suggested that NS-MRH is equivalent to MRH for the treatment of cervical cancer and may be superior in reducing pelvic floor dysfunction rates. However, because of the low level of evidence of the included studies, further randomized trials are warranted.

PMID- 29191473 TI - Dopamine receptors and BDNF-haplotypes predict dyskinesia in Parkinson's disease. AB - OBJECTIVE: Dyskinesia is a known side-effect of the treatment of Parkinson's Disease (PD). We examined the influence of haplotypes in three dopamine receptors (DRD1, DRD2 and DRD3) and the Brain Derived Neurotrophic Factor (BDNF) on dyskinesia. METHODS: Patient data were drawn from a population-based case-control study. We included 418 patients with confirmed diagnoses by movement disorder specialists, using levodopa and a minimum three years disease duration at the time of assessment. Applying Haploview and Phase, we created haploblocks for DRD1 3 and BDNF. Risk scores for DRD2 and DRD3 were generated. We calculated risk ratios using Poisson regression with robust error variance. RESULTS: There was no difference in dyskinesia prevalence among carriers of various haplotypes in DRD1. However, one haplotype in each DRD2 haploblocks was associated with a 29 to 50% increase in dyskinesia risk. For each unit increase in risk score, we observed a 16% increase in dyskinesia risk for DRD2 (95%CI: 1.05-1.29) and a 17% (95%CI: 0.99-1.40) increase for DRD3. The BDNF haploblock was not associated, but the minor allele of the rs6265 SNP was associated with dyskinesia (adjusted RR 1.31 (95%CI: 1.01-1.70)). CONCLUSION: Carriers of DRD2 risk haplotypes and possibly the BDNF variants rs6265 and DRD3 haplotypes, were at increased risk of dyskinesia, suggesting that these genes may be involved in dyskinesia related pathomechanisms. PD patients with these genetic variants might be prime candidates for treatments aiming to prevent or delay the onset of dyskinesia. PMID- 29191474 TI - Chikungunya-related erosive arthritis: case report and literature review. AB - Chikungunya virus infection (CHIKV) is associated with joint involvement in half of the cases. This can lead to erosive arthritis which, given the high intervariability of clinical and serological presentations, and the probable role of genetic conditioning in the severity and chronification of the condition, represents a great diagnostic and therapeutic challenge. There is an important lack of scientific evidence that would enable us to characterize the variability of the patient and choose the most appropriate approach. PMID- 29191475 TI - Evaluation of Bruker Biotyper and Vitek MS for the identification of Candida tropicalis on different solid culture media. AB - BACKGROUND: The aim of this study was to investigate the performance of the Bruker Biotyper matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and Vitek MS systems for identification of genetically-confirmed blood isolates of Candida tropicalis that had been grown on several types of culture media commonly used for primary fungal isolation. METHODS: Isolates included 105 from the National China Hospital Invasive Fungal Surveillance Net program (CHIF-NET) and 120 from National Taiwan University Hospital (NTUH). Culture media tested for CHIF-NET isolates included trypticase soy agar supplemented with 5% sheep blood (BAP), Sabouraud dextrose agar (SDA-C), CHROMagar, China blue agar (CBA), chocolate agar supplemented with vancomycin (CAP-VA), and MacConkey agar (MAC). Culture media used for NTUH isolates included BAP, SDA, CHROMagar, eosin methylene blue (EMB), inhibitory mold agar (IMA), Mycosel agar, and cornmeal agar (CMA). RESULTS: The Bruker Biotyper correctly identified all CHIF-NET isolates to the species level on all six agar media tested and correctly identified the majority of NTUH isolates with the exception of isolates grown on SDA (85.8%) and CMA (52.5%). The Vitek MS system correctly identified all CHIF-NET isolates to the species level with the exception of isolates grown on CHROMagar (84.8%), and correctly identified the majority of NTUH isolates with the exception of isolates grown on SDA (51.7%), Mycosel agar (57.5%), and CMA (9.2%) for NTUH isolates. CONCLUSION: Clinical microbiologists should be aware that different culture media can affect the performance of the Bruker Biotyper MALDI-TOF MS and Vitek MS systems in identifying C. tropicalis. PMID- 29191476 TI - The association between serum uric acid and asymptomatic intracranial arterial stenosis in middle-aged Koreans. AB - BACKGROUND AND AIMS: Intracranial arterial stenosis (ICAS) is one of the most common causes of stroke, especially in Asians. Hyperuricemia has been associated with an increased risk of comorbidities such as metabolic syndrome or cardiovascular diseases. However, there are few studies focusing on the association between serum uric acid (SUA) levels and asymptomatic ICAS. The aim of this study was to explore the association between SUA and the prevalence of ICAS in middle-aged Korean health screening examinees. METHODS AND RESULTS: A cross-sectional study was performed on 9417 males and 7755 females who underwent a comprehensive health examination including transcranial Doppler (TCD) ultrasonography. The association of SUA and ICAS was analyzed using multivariate logistic regression. The prevalence of ICAS among the total examinee population was 3.55%. In females, the multivariate-adjusted odds ratio for ICAS was 1.52 (confidence interval 1.13-2.04) in the 3rd quartile of SUA and 1.45 (1.05-2.00) in the highest quartile, compared to the reference (P for trend 0.008). This trend was evident in all clinically relevant subgroups evaluated, including women with low inflammation status. SUA was not significantly associated with the prevalence of ICAS among males. In a sensitivity analysis, the multivariate adjusted odds ratio of middle cerebral artery stenosis in females was 1.60 (1.09 2.37) in the highest quartile compared to the reference (P for trend 0.023). CONCLUSIONS: Higher SUA level was associated with increased risk of ICAS among middle-aged females but not males. A further cohort study is warranted to elucidate the effect of SUA on asymptomatic ICAS. PMID- 29191477 TI - Improved three-dimensional multi-echo gradient echo based myelin water fraction mapping with phase related artifact correction. AB - Myelin water fraction (MWF) mapping with a multi-echo gradient echo (mGRE) sequence using complex-value based model fitting approach was recently described, in which the phase of the data plays an important role in the accuracy of the fitting results. Thus, influences coming from the undesirable phase components need to be reduced. Targeted for improved MWF mapping, methods to combat these phase related issues which include offset correction, main magnetic field (B0) inhomogeneity related correction, and flow compensation have been developed. For offset correction, a coil combine method with bipolar readout gradients has been devised. For B0 related artifact, a voxel spread function correction approach along with a navigator echo acquisition was utilized. Finally, flow compensation gradients were used to reduce the effects of flow from regions including the veins. The correction methods led to reduced residual fitting error and improved quality of the resultant MWF maps. Quantitative analysis shows increased reliability when the corrections were used. Data from normal volunteers showed improved MWF mapping with the integrated method developed in this work. PMID- 29191478 TI - Repetitive transcranial magnetic stimulation over dorsolateral prefrontal cortex modulates value-based learning during sequential decision-making. AB - Adaptive behavior in daily life often requires the ability to acquire and represent sequential contingencies between actions and the associated outcomes. Although accumulating evidence implicates the role of dorsolateral prefrontal cortex (dlPFC) in complex value-based learning and decision-making, direct evidence for involvements of this region in integrating information across sequential decision states is still scarce. Using a 3-stage deterministic Markov decision task, here we applied offline, inhibitory low-frequency 1-Hz repetitive transcranial magnetic stimulation (rTMS) over the left dlPFC in young male adults (n = 31, mean age = 23.8 years, SD = 2.5 years) in a within-subject cross-over design to study the roles of this region in influencing value-based sequential decision-making. In two separate sessions, each participant received 1-Hz rTMS stimulation either over the left dlPFC or over the vertex. The results showed that transiently inhibiting the left dlPFC impaired choice accuracy, particularly in situations in which the acquisition of sequential transitions between decision states and temporally lagged action-outcome contingencies played a greater role. Estimating parameters of a diffusion model from behavioral choices, we found that the diffusion drift rate, which reflects the efficiency of information integration, was attenuated by the stimulation. Moreover, the effects of rTMS interacted with session: individuals who could not efficiently integrate information across sequential states in the first session due to disrupted dlPFC function also could not catch up in performance during the second session with those individuals who could learn sequential transitions with intact dlPFC function in the first session. Taken together, our findings suggest that the left dlPFC is crucially involved in the acquisition of complex sequential relations and in the potential of such learning. PMID- 29191479 TI - The spatiotemporal pattern of pure tone processing: A single-trial EEG-fMRI study. AB - Although considerable research has been published on pure tone processing, its spatiotemporal pattern is not well understood. Specifically, the link between neural activity in the auditory pathway measured by functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) markers of pure tone processing in the P1, N1, P2, and N4 components is not well established. In this study, we used single-trial EEG-fMRI as a multi-modal fusion approach to integrate concurrently acquired EEG and fMRI data, in order to understand the spatial and temporal aspects of the pure tone processing pathway. Data were recorded from 33 subjects who were presented with stochastically alternating pure tone sequences with two different frequencies: 200 and 6400 Hz. Brain network correlated with trial-to-trial variability of the task-discriminating EEG amplitude was identified. We found that neural responses responding to pure tone perception are spatially along the auditory pathway and temporally divided into three stages: (1) the early stage (P1), wherein activation occurs in the midbrain, which constitutes a part of the low level auditory pathway; (2) the middle stage (N1, P2), wherein correlates were found in areas associated with the posterodorsal auditory pathway, including the primary auditory cortex and the motor cortex; (3) the late stage (N4), wherein correlation was found in the motor cortex. This indicates that trial-by-trial variation in neural activity in the P1, N1, P2, and N4 components reflects the sequential engagement of low- and high-level parts of the auditory pathway for pure tone processing. Our results demonstrate that during simple pure tone listening tasks, regions associated with the auditory pathway transiently correlate with trial-to-trial variability of the EEG amplitude, and they do so on a millisecond timescale with a distinct temporal ordering. PMID- 29191480 TI - Preterm birth leads to hyper-reactive cognitive control processing and poor white matter organization in adulthood. AB - Individuals born preterm with very low birth weight (VLBW; birth weight <= 1500 g) are at high risk for perinatal brain injuries and deviant brain development, leading to increased chances of later cognitive, emotional, and behavioral problems. Here we investigated the neuronal underpinnings of both reactive and proactive cognitive control processes in adults with VLBW. We included 32 adults born preterm with VLBW (before 37th week of gestation) and 32 term-born controls (birth weight >=10th percentile for gestational age) between 22 and 24 years of age that have been followed prospectively since birth. Participants performed a well-validated Not-X continuous performance test (CPT) adapted for use in a mixed block- and event-related fMRI protocol. BOLD fMRI and DTI data was acquired on a 3T scanner. Performance on the Not-X CPT was highly similar between groups. However, the VLBW group demonstrated hyper-reactive cognitive control processing and disrupted white matter organization. The hyper-reactive brain activation signature in VLBW adults was associated with lower gestational age, lower fluid intelligence score, and anxiety problems. Automated Multi-Atlas Tract Extraction (AutoMATE) analyses revealed that this disruption of normal brain function was accompanied by poorer white matter organization in the anterior thalamic radiation and the cingulum, as reflected in both reduced fractional anisotropy and increased mean diffusivity. These findings show that the preterm behavioral phenotype is associated with predominantly reactive-, rather than proactive cognitive control processing, as well as white matter abnormalities, that may underlie common difficulties that many preterm born individuals experience in everyday life. PMID- 29191481 TI - Surface engineered excipients: I. improved functional properties of fine grade microcrystalline cellulose. AB - Excipients with good flowability, bulk density as well as compaction properties are desired for use in tableting since they play important roles in formulation development and processing, including, handling, mixing, feeding and compaction. The objective of this paper is to examine the feasibility of using dry coating based surface modification of microcrystalline cellulose, Avicel PH-105, to produce an engineered fine grade (<30 MUm) excipient that has all three desired properties. Using a material sparing high-intensity vibrational mixer, Avciel PH 105 is dry coated with 1 wt% Aerosil 200, selected due to its relatively higher dispersive surface energy and lower particle size amongst other silica choices. The results indicated that as expected, the bulk density and flowability are significantly improved, while there was an appreciable loss of compaction. To minimize the loss of compaction, attributed to decreased surface energy after coating, while maintaining improved bulk density and flowability, the effect of reduced silica amount was examined. Remarkably, at reduced levels (0.5 wt% to 0.7 wt%) of Aerosil 200, significant improvements in bulk density and flowability were attained with only 9%-12% compaction reduction. The properties of the surface-engineered excipients were compared with several other commercially available pharmaceutical excipients using two different processibility or regime maps; tablet tensile strength versus bulk density or flow function coefficient (FFC). The surface engineered excipients exhibited the best overall performance establishing a promising pathway to engineer excipients using dry processing instead of complex processes such as spray drying. PMID- 29191482 TI - Multivariate modeling of diffuse reflectance infrared fourier transform (DRIFT) spectra of mixtures with low-content polymorphic impurities with analysis of outliers. AB - Diffuse Reflectance Fourier Transform Infrared Spectroscopy (DRIFTS)-based multivariate models were developed to quantify the content of two polymorphic impurities in mixtures with the desired active pharmaceutical ingredient (API) form, with the impurities not exceeding 2% wt/wt. In addition, close attention was paid to the outlier detection criteria: Q residuals; Hotelling T2; and score bi-plot. While reasonably accurate results were obtained for the relatively simple calibration models for both forms of the impurity, the predictions for "blank" samples (separately verified to be impurity-free) were apparently biased. Thus, the model training sets were augmented with spectra from calibration mixtures incorporating some of the API from batches used in the prediction. The performance of the updated models as assessed by cross-validation was somewhat degraded as a result, while predictions against independent batches of API showed a decrease in bias indicating robustness had improved. Nevertheless, the Q residuals criterion disqualified a large number of prediction samples as outliers in contrast to the other two criteria that reported no issues at all. The results here demonstrated the effectiveness of DRIFTS for quantifying low concentration polymorphic impurities, while simultaneously highlighting the variability issues that can be encountered in practice and which need to be understood and managed appropriately to ensure the success of any automated or Good Manufacturing Practice (GMP) compliant application of multivariate modeling. PMID- 29191484 TI - Parameter study of shipping conditions for the ready-to-use application of a 3D human hemicornea construct in drug absorption studies. AB - In this study, a shipping protocol for our 3D human hemicornea (HC) construct should be developed to provide quality-maintaining shipping conditions and to allow its ready-to-use application in drug absorption studies. First, the effects of single and multiple parameters, such as the type of shipping container, storage temperature and CO2 supply, were investigated under controlled laboratory conditions by assessing cell viability via MTT dye reaction and epithelial barrier properties via transepithelial electrical resistance (TEER) measurements. These investigations showed that TEER is more susceptible to shipping parameters than cell viability. Furthermore, the results were used to determine the optimal shipping conditions and critical values for subsequent overnight, real-time shipping experiments. Epithelial barrier properties were then investigated via TEER and the permeation of sodium fluorescein for shipped and not shipped HC. The results underscore that acceleration forces and changes in position may have a great impact on the epithelial barrier of 3D models. Low acceleration values and short changes in position caused only minor impairments. However, combined or intensive separate effects resulted in considerably low yields after shipping. Consequently, barrier-maintaining shipping of 3D in vitro models seems to be challenging, as mechanical forces have to be reduced to a minimum. PMID- 29191483 TI - Advances in bioresponsive closed-loop drug delivery systems. AB - Controlled drug delivery systems are able to improve efficacy and safety of therapeutics by optimizing the duration and kinetics of release. Among them, closed-loop delivery strategies, also known as self-regulated administration, have proven to be a practical tool for homeostatic regulation, by tuning drug release as a function of biosignals relevant to physiological and pathological processes. A typical example is glucose-responsive insulin delivery system, which can mimic the pancreatic beta cells to release insulin with a proper dose at a proper time point by responding to plasma glucose levels. Similar self-regulated systems are also important in the treatment of other diseases including thrombosis and bacterial infection. In this review, we survey the recent advances in bioresponsive closed-loop drug delivery systems, including glucose-responsive, enzyme-activated, and other biosignal-mediated delivery systems. We also discuss the future opportunities and challenges in this field. PMID- 29191486 TI - Pulmonary Alveolar Proteinosis: Crazing-Paving Appearance. PMID- 29191485 TI - Impact of non-binder ingredients and molecular weight of polymer binders on heat assisted twin screw dry granulation. AB - Two grades of commercial AFFINISOLTM HPMC HME were used as polymer binders to explore the influence of polymer viscosity and concentration on a novel heat assisted dry granulation process with a twin screw extruder. Contributions of other non-binder ingredients in the formulations were also studied for lactose, microcrystalline cellulose and an active pharmaceutical ingredient of caffeine. As sensitive indicators of processing conditions that expose the drug to high internally generated heat, dehydration of alpha-lactose monohydrate and polymorphic transformation of caffeine were monitored by differential scanning calorimetry (DSC) and powder X-ray diffraction (XRD). Additionally, any decomposition of caffeine was determined by high-performance liquid chromatography (HPLC). Granular samples were characterized by particle size, circularity, fracture strength and their temperature on the exit of extruder. Higher screw speed and lower feed rate were found to help particles agglomerate by allowing feed particles a greater opportunity to increase in temperature. Lower binder molecular weight and higher binder concentration enable granules to build stronger strength and thereby lead to higher particle size. This new twin screw dry granulation was demonstrated as offering advantages over conventional hot melt granulation by minimizing thermal degradation of the tested ingredients. PMID- 29191487 TI - The Physician From Vienna. PMID- 29191488 TI - Introduction to Neuroimaging. AB - Primary care physicians are often tasked with evaluating neurologic symptoms, and imaging plays a critical role in neurologic diagnoses. Neuroradiology routinely employs advanced imaging modalities, and hence, determination of the appropriate imaging test and interpretation of findings in the clinical context can understandably be overwhelming. In this review article, we introduce resources that can guide physicians in the selection of neuroimaging tests and summarize guidelines on contrast agent administration. Key concepts on imaging techniques and terminology are reviewed, as is relevant for the primary care physician. We then present an overview of the typical imaging manifestations of brain pathologies, including stroke, traumatic injuries, infections, demyelinating and neurodegenerative processes, and neoplasms. Spine imaging is often considered for the evaluation of degenerative, infectious, or neoplastic etiologies, and the typical imaging findings in these scenarios are also summarized. PMID- 29191489 TI - Beyond the vicious cycle: The role of innate osteoimmunity, automimicry and tumor inherent changes in dictating bone metastasis. AB - Bone metastasis is a fatal consequence of a subset of solid malignancies that fail to respond to conventional therapies. While a myriad of factors contribute to osteotropism and disseminated cell survival and outgrowth in bone, efforts to inhibit tumor cell growth in the bone-metastatic niche have largely relied on measures that disrupt the bi-directional interactions between bone resident and tumor cells. However, the targeting of isolated stromal interactions has proven ineffective to date in inhibiting bone-metastatic progression and patient mortality. Osteoimmune regulation is now emerging as a critical determinant of metastatic growth in the bone microenvironment. While this has highlighted the importance of innate immune populations in dictating the temporal development of overt bone metastases, the osteoimmunological processes that underpin tumor cell progression in bone remain severely underexplored. Along with tumor-intrinsic alterations that occur specifically within the bone microenvironment, innate osteoimmunological crosstalk poses an exciting area of future discovery and therapeutic development. Here we review current knowledge of the unique exchange that occurs between bone resident cells, innate immune populations and tumor cells that leads to the establishment of a tumor-permissive milieu. PMID- 29191490 TI - Prognosticating Clinical Prediction Scores Without Clinical Gestalt for Patients With Chest Pain in the Emergency Department. AB - BACKGROUND: Assessment of patients with chest pain is a regular challenge in the emergency department (ED). Recent guidelines recommended quantitative assessment of ischemic risk by means of risk scores. OBJECTIVE: Our aim was to assess the performance of Thrombosis in Myocardial Infarction (TIMI); Global Registry of Acute Coronary Events (GRACE); history, electrocardiogram, age, risk factors, and troponin (HEART) scores; and the North America Chest Pain Rule (NACPR) without components of clinical gestalt in predicting 30-day major adverse cardiac events (MACE). METHODS: We performed a prospective cohort study in adult patients who attended the ED with undifferentiated chest pain. Clinical prediction rules were applied and calculated. The clinical prediction rules were modified from the original ones, excluding components requiring judgment by clinical gestalt. The primary outcome was MACE. Performance of the tests were evaluated by receive operating characteristic curves and the area under curves (AUC). RESULTS: There were 1081 patients included in the study. Thirty-day MACE occurred in 164 (15.2%) patients. The AUC of the GRACE score was 0.756, which was inferior to the TIMI score (AUC 0.809) and the HEART score (AUC 0.845). A TIMI score >= 1 had a sensitivity of 97% and a specificity of 45.7%. A GRACE score >= 50 had a sensitivity of 99.4% and a specificity of 7.5%. A HEART score >= 1 had a sensitivity of 98.8% and a specificity of 11.7%. The NACPR had a sensitivity of 93.3% and a specificity of 51.5%. CONCLUSIONS: Without clinical gestalt, the modified HEART score had the best discriminative capacity in predicting 30-day MACE. PMID- 29191491 TI - A nested-PCR strategy for molecular diagnosis of mollicutes in uncultured biological samples from cows with vulvovaginitis. AB - Bacteria classified in Mycoplasma (M. bovis and M. bovigenitalium) and Ureaplasma (U. diversum) genera are associated with granular vulvovaginitis that affect heifers and cows at reproductive age. The traditional means for detection and speciation of mollicutes from clinical samples have been culture and serology. However, challenges experienced with these laboratory methods have hampered assessment of their impact in pathogenesis and epidemiology in cattle worldwide. The aim of this study was to develop a PCR strategy to detect and primarily discriminate between the main species of mollicutes associated with reproductive disorders of cattle in uncultured clinical samples. In order to amplify the 16S 23S rRNA internal transcribed spacer region of the genome, a consensual and species-specific nested-PCR assay was developed to identify and discriminate between main species of mollicutes. In addition, 31 vaginal swab samples from dairy and beef affected cows were investigated. This nested-PCR strategy was successfully employed in the diagnosis of single and mixed mollicute infections of diseased cows from cattle herds from Brazil. The developed system enabled the rapid and unambiguous identification of the main mollicute species known to be associated with this cattle reproductive disorder through differential amplification of partial fragments of the ITS region of mollicute genomes. The development of rapid and sensitive tools for mollicute detection and discrimination without the need for previous cultures or sequencing of PCR products is a high priority for accurate diagnosis in animal health. Therefore, the PCR strategy described herein may be helpful for diagnosis of this class of bacteria in genital swabs submitted to veterinary diagnostic laboratories, not demanding expertise in mycoplasma culture and identification. PMID- 29191492 TI - Initial clinical assessment of "center-specific" automated treatment plans for low-dose-rate prostate brachytherapy. AB - PURPOSE: To report results of an initial pilot study assessing iodine-125 prostate implant treatment plans created automatically by a new seed-placement method. METHODS AND MATERIALS: A novel mixed-integer linear programming method incorporating spatial constraints on seed locations in addition to standard dose volume constraints was used to place seeds. The approach, described in detail elsewhere, was used to create treatment plans fully automatically on a retrospective basis for 20 patients having a wide range of prostate sizes and shapes. Corresponding manual plans used for patient treatment at a single institution were combined with the automated plans, and all 40 plans were anonymized, randomized, and independently evaluated by five clinicians using a common scoring tool. Numerical and clinical features of the plans were extracted for comparison purposes. RESULTS: A full 51% of the automated plans were deemed clinically acceptable without any modification by the five practitioners collectively versus 90% of the manual plans. Automated plan seed distributions were for the most part not substantially different from those for the manual plans. Two observed shortcomings of the automated plans were seed strands not intersecting the prostate and strands extending into the bladder. Both are amenable to remediation by adjusting existing spatial constraints. CONCLUSIONS: After spatial and dose-volume constraints are set, the mixed-integer linear programming method is capable of creating prostate implant treatment plans fully automatically, with clinical acceptability sufficient to warrant further investigation. These plans, intended to be reviewed and refined as necessary by an expert planner, have the potential to both save planner time and enhance treatment plan consistency. PMID- 29191493 TI - Effects of melatonin supplementation on blood lipid concentrations: A systematic review and meta-analysis of randomized controlled trials. AB - BACKGROUND & AIMS: Melatonin supplementation may be associated with blood lipids improvement; however, the current evidence from randomized controlled trials (RCTs) is inconsistent. The present study aimed to systematically review and analyze RCTs assessing the effects of melatonin supplementation on blood lipids. METHODS: A comprehensive literature search in several database was performed up to January 2017. Quantitative data synthesis was performed using a fixed or random-effects model, with weight mean difference (WMD) and 95% confidence intervals (CI). Standard methods were used for assessment of heterogeneity, meta regression, sensitivity analysis and publication bias. RESULTS: A total of 8 RCTs were eligible. Meta-analysis suggested a significant association between melatonin supplementation and a reduction in triglycerides (WMD: -31.54 mg/dL, 95% CI: -50.71, -12.38, p = 0.001), and total cholesterol levels (WMD: -18.48 mg/dL, 95% CI: -35.33, -1.63, p = 0.032), while no significant effect on LDL-C (WMD: -2.37 mg/dL, 95% CI: -11.61, -6.86, p = 0.615) and HDL-C (WMD: 1.28 mg/dL, 95% CI: -0.66, 3.23, p = 0.197) was found. In sub-group analysis, a significant decrease in triglycerides was found at doses >=8 mg/d and when trials last >=8 weeks. In addition, a significant decrease of total cholesterol was found at doses >=8 mg/d and when total cholesterol baseline levels were >=200 mg/dL. CONCLUSIONS: Melatonin supplementation has significant effects on triglycerides and total cholesterol levels, which was more evident in higher dose and longer duration and also in a higher concentration of cholesterol levels. Further studies are required to determine the benefits of melatonin on lipid profile. PMID- 29191494 TI - Low protein intake, muscle strength and physical performance in the very old: The Newcastle 85+ Study. AB - BACKGROUND: Low protein intake has been linked to reduced muscle strength and physical performance in older adults but little is known about how it may affect muscle health and subsequent functional decline in the very old (aged 85+), who are at enhanced risk of malnutrition and loss of muscle mass and strength. AIMS: To investigate the associations between low protein intake, defined as the intake of <1 g protein/kg adjusted body weight/day (<1 g/kg aBW/d) and decline in muscle strength and physical performance in the very old. METHODS: The analytic sample consisted of 722 community-dwelling participants (60% women) from the Newcastle 85+ Study who had protein intake at baseline. Participants were followed-up for change in grip strength (GS) and Timed Up-and-Go (TUG) test over 5 years (baseline, 18, 36, and 60 months). We used mixed models to determine the effects of low protein intake on muscle strength and physical performance in all participants, and also stratified by sex. RESULTS: At baseline, 390 (54%) participants (261 women, p < 0.001) reported low protein intake, and these differed from participants with good intake (>=1 g/kg aBW/d) on several measures of health and function. In the model adjusted for protein intake, consuming <1 g/kg aBW/d of protein was associated with a 1.62 kg lower GS (p = 0.008) in all participants, and especially in women (beta (SE) = -0.83 (0.41), p = 0.05) after adjusting for key baseline covariates (anthropometry, multimorbidity, arthritis in hands, cognitive status and physical activity). The rate of decline in GS over 5 years was not associated with protein intake. Women, but not men, with low protein intake had worse baseline TUG (beta (SE) = 0.04 (0.02), p = 0.03) compared with those with good protein intake in the fully adjusted model, but the rate of decline in TUG was not affected by daily protein status. CONCLUSIONS: Intake of <1 g protein/kg aBW/d may negatively affect muscle strength and physical performance in late life, especially in older women, independently of important covariates. More research is needed in the very old to define the optimal protein intake for maintenance of muscle health and function. PMID- 29191495 TI - Atopic disorders in CHARGE syndrome: A retrospective study and literature review. AB - BACKGROUND: Atopic disorders have been reported in CHARGE syndrome, but the prevalence and underlying mechanisms are not known. METHODS: We performed a retrospective study of atopic disorders in 23 individuals with CHARGE syndrome, and reviewed other published reports of atopic disorders in CHARGE syndrome. We assayed for enrichment of atopic disorders in CHARGE syndrome based on gender and presence of a CHD7 pathogenic variant. RESULTS: In our cohort, 65% (15/23) of individuals with CHARGE syndrome were found to have a pathogenic CHD7 variant. Overall, 65% (15/23) of individuals with CHARGE had atopic disorders. Among the 23 individuals with CHARGE, 22% (5/23) had food allergy, 26% (6/23) exhibited drug allergy, 22% (5/23) had contact allergy, 9% (2/23) had allergic rhinitis, and 22% (5/23) had asthma. In our cohort, the proportion of males to females with CHARGE and atopic disorders was 11:4 (P < 0.01), and there was no significant difference between atopic disorders in individuals with CHD7 pathogenic variants and those without CHD7 pathogenic variants (P > 0.05). CONCLUSION: In our cohort of 23 individuals with CHARGE syndrome, 15 (65%) exhibited atopic disorders, with a slight male predominance. PMID- 29191496 TI - A higher rare CNV burden in the genetic background potentially contributes to intellectual disability phenotypes in 22q11.2 deletion syndrome. AB - The 22q11.2 deletion syndrome (22q11DS), the most common survivable human genetic deletion disorder, is caused by a hemizygous deletion of 30-40 contiguous genes on chromosome 22, many of which have not been well characterized. Clinical features seen in patients with this deletion, including intellectual disability, are not completely penetrant and vary in severity between patients, suggesting the involvement of variants elsewhere in the genome in the manifestation of the phenotype. Given that it is a relatively rare disorder (1/2000-6000 in humans), limited research has shed light into the contribution of these second-site variants to the developmental pathogenesis that underlies 22q11DS. As CNVs throughout the genome might constitute such a genetic risk factor for variability in the 22q11DS phenotypes such as intellectual disability, we sought to determine if the overall burden of rare CNVs in the genetic background influenced the phenotypic variability. We analyzed CNV and clinical data from 66 individuals with 22q11DS, and found that 77% (51/66) of individuals with the 22q11DS also carry additional rare CNVs (<0.1% frequency). We observed several trends between CNV burden and phenotype, including that the burden of large rare CNVs (>200 Kb in size) was significantly higher in 22q11DS individuals with intellectual disability than with normal IQ. Our analysis shows that rare CNVs may contribute to intellectual disability 22q11DS, and further analysis on larger 22q11DS cohorts should be performed to confirm this correlation. PMID- 29191497 TI - Recontacting in light of new genetic diagnostic techniques for patients with intellectual disability: Feasibility and parental perspectives. AB - A higher diagnostic yield from new diagnostic techniques makes re-evaluation in patients with intellectual disability without a causal diagnosis valuable, and is currently only performed after new referral. Active recontacting might serve a larger group of patients. We aimed to evaluate parental perspectives regarding recontacting and its feasibility in clinical genetic practice. A recontacting pilot was performed in two cohorts of children with intellectual disability. In cohort A, parents were recontacted by phone and in cohort B by letter, to invite them for a re-evaluation due to the new technologies (array CGH and exome sequencing, respectively). Parental opinions, preferences and experiences with recontacting were assessed by a self-administered questionnaire, and the feasibility of this pilot was evaluated. 47 of 114 questionnaires were returned. In total, 87% of the parents believed that all parents should be recontacted in light of new insights, 17% experienced an (positive or negative) emotional reaction. In cohort A, approached by phone, 36% made a new appointment for re evaluation, and in cohort B, approached by letter, 4% did. Most parents have positive opinions on recontacting. Recontacting might evoke emotional responses that may need attention. Recontacting is feasible but time-consuming and a large additional responsibility for clinical geneticists. PMID- 29191498 TI - A report of three families with FBN1-related acromelic dysplasias and review of literature for genotype-phenotype correlation in geleophysic dysplasia. AB - Acromelic dysplasia is a heterogeneous group of rare skeletal dysplasias characterized by distal limb shortening. Weill-Marchesani syndrome (WMS), Geleophysic dysplasia (GD) and Acromicric dysplasia (AD) are clinically distinct entities within this group of disorders and are characterized by short stature, short hands, stiff joints, skin thickening, facial anomalies, normal intelligence and skeletal abnormalities. Mutations of the Fibrillin-1 (FBN1) gene have been reported to cause AD, GD and related phenotypes. We reported three families with acromelic short stature. FBN1 analysis showed that all affected individuals carry a heterozygous missense mutation c.5284G > A (p.Gly1762Ser) in exon 42 of the FBN1 gene. This mutation was previously reported to be associated with GD. We reviewed the literature and compared the clinical features of the patients with FBN1 mutations to those with A Distintegrin And Metalloproteinase with Thrombospondin repeats-like 2 gene (ADAMTSL2) mutations. We found that tip-toeing gait, long flat philtrum and thin upper upper lip were more consistently found in GD patients with ADAMTSL2 mutations than in those with FBN1 mutations. The results have shed some light on the phenotype-genotype correlation in this group of skeletal disorders. A large scale study involving multidisciplinary collaboration would be needed to consolidate our findings.

PMID- 29191500 TI - 3T non-injected phase-contrast MRI sequences for the mapping of the external carotid branches: In vivo radio-anatomical pilot study for feasibility analysis. AB - An essential stage in head and neck microsurgical reconstruction is the choice of recipient vessels. To make relevant choices, surgeons must rely on accurate imaging techniques. The objective of the study was to examine the feasibility of Phase-Contrast sequences to conduct the pre-operative tests without injection and provide precise radio-anatomical data over the entire vessel region. The challenges were the large velocity range, the lack of contrast, and the large spatial resolution needed to image vessels below 5 mm in diameter. Thirty-one healthy volunteers were included in an MRI prospective study. The anatomical and morphometrical characteristics of the collaterals of the external carotid artery were determined associating 3D PCA and 2D Cine MRI-PC sequences (average protocole duration time of 49 min +/- 4 min). The average diameter was measured to be 2.1 +/- 1.4 mm for the superior thyroid artery, 2.2 +/- 1.1 mm for the lingual artery, 2.7 +/- 1.6 mm for the facial artery, 2.6 +/- 1.4 mm for the internal maxillary artery, and 2 +/- 1.4 mm for the superficial temporal artery. With a vessel identification success rate of 98%, the study showed for the first time that Phase Contrast MRI allowed non-invasive and non-operator dependent anatomical analyses of small caliber vessels without the use of agent contrast. It also proved that the designed sequences could be used on patients and provided valuable pre-operative information for head and neck surgery. PMID- 29191501 TI - Immunoprecipitation high performance liquid chromatographic analysis of healing process in chronic suppurative osteomyelitis of the jaw. AB - PURPOSE: Chronic suppurative osteomyelitis (CSO) of the jaw is one of the most difficult infectious diseases to manage, because it causes progressive bony destruction and is associated with bacterial inhabitation of the sequestra. A combination of antibiotic therapy and surgical debridement is often used to treat CSO. Nevertheless, various systemic conditions can lead to life-threatening complications. METHODS: The present study aimed to explore the wound healing progress in 16 cases of CSO through protein expression analysis of postoperative exudates (POE) that were collected 6 h, 1 day, and 2 days after saucerization and/or decortication. A bony lesion was removed during surgery and then examined pathologically, and the CSO POE was examined by immunoprecipitation thus high performance chromatography (IP-HPLC). The POE at 6 h was used as a comparative control. RESULTS: Histologically the CSO lesion showed a necrotic granulomatous lesion heavily infiltrated with polymorphonuclear leukocytes, macrophages, and plasma cells, admixed with multiple sequestra inhabited by bacterial colonies. The IP-HPLC analysis displayed a slight increase in innate immunity-related proteins, i.e., NFkB, TNFalpha, IL-1, IL-6, IL-28, and LL-37, but a gradual decrease of bacteria-related inflammatory proteins, i.e., IL-8, IL-12, CD31, CD68, and lysozyme. The angiogenesis-related proteins, i.e., VEGF-A and VEGF-C, were slightly decreased but TGF-beta1 and bFGF were markedly increased on day 2. The osteogenesis-related proteins, i.e., OPG and ALP, were slightly increased, while the osteoclastogenesis-related protein, RANKL was slightly decreased compared to the control. CONCLUSION: These findings indicate that the infected CSO undergoes a rapid wound healing process with active osteogenesis and a gradual decrease in bacteria-related inflammation, predicting a favorable prognosis after surgery. Moreover, IP-HPLC can be useful in monitoring the POE and wound healing processes during the postoperative period. PMID- 29191502 TI - Synthesis, in vitro and in silico evaluation of novel trans-stilbene analogues as potential COX-2 inhibitors. AB - 25 new trans-stilbene and trans-stilbazole derivatives were investigated using in vitro and in silico techniques. The selectivity and potency of the compounds were assessed using commercial ELISA test. The obtained results were incorporated into 2D QSAR assay. The most promising compound 4-nitro-3',4',5'-trihydroxy-trans stilbene (N1) was synthetized and its potency and selectivity were confirmed. N1 was classified as preferential COX-2 inhibitor. Its ability to inhibit COX-2 in MCF-7 cell line was established and its cytotoxicity by MTT test was assessed. The compound was more cytotoxic than celecoxib within studied concentration range. Finally, the investigated trans-stilbene was docked into COX-1 and COX-2 active sites using "CDOCKER" protocol. PMID- 29191504 TI - Predictors of In-Hospital Mortality in Patients With ST-Segment Elevation Myocardial Infarction Complicated With Cardiogenic Shock. AB - BACKGROUND: ST-segment elevation myocardial infarction (STEMI) complicated with cardiogenic shock (CS) remains as an unresolved condition causing high morbidity and mortality despite advances in medical treatment and coronary intervention procedures. In the current study, we evaluated the predictors of in-hospital mortality of STEMI complicated with CS. METHODS: In this retrospective study, we evaluated the predictive value of baseline characteristics, angiographic, echocardiographic and laboratory parameters on in-hospital mortality of 319 patients with STEMI complicated with CS who were treated with primary percutaneous coronary intervention. Patients were divided into two groups consisting of survivors and non-survivors during their index hospitalisation period. RESULTS: The mortality rate was found to be 61.3% in the study population. At multivariate analysis after adjustment for the parameters detected in univariate analysis, chronic renal failure, Thrombolysis In Myocardial Infarction (TIMI) post percutaneous coronary intervention (PCI) <=2, plasma glucose and lactate level, blood urea nitrogen level, Tricuspid Annular Plane Systolic Excursion (TAPSE) and ejection fraction were independent predictors of in-hospital mortality. CONCLUSIONS: Apart from haemodynamic deterioration, angiographic, echocardiographic and laboratory parameters have an impact on in hospital mortality in patients with STEMI complicated with CS. PMID- 29191503 TI - Management of Adults With Congenital Heart Disease and Pulmonary Arterial Hypertension in the UK: Survey of Current Practice, Unmet Needs and Expert Commentary. AB - BACKGROUND: Pulmonary arterial hypertension (PAH) is a well-recognised complication of adult congenital heart disease (CHD). However, management is not currently standardised between centres and specific guidelines are lacking. In order to identify and understand the unmet needs related to PAH associated with CHD (PAH-CHD), a survey of physicians was performed. METHODS: An electronic survey was sent to two physician groups: (1) cardiologists registered in a UK cardiology directory; (2) specialist pulmonary hypertension (PH) physicians known to manage patients with adult PAH-CHD. The questions related to referral pathways, screening, therapy and palliative care. RESULTS: 821 surveys were distributed and 106 were returned. Respondents included a broad mix of specialist physicians with many patients along with general cardiologists managing only a small number of PAH-CHD patients. Although 97% of respondents have access to a specialist PH centre, patients are still being managed in non-specialist settings. Shared care arrangements are widespread but only 41% have formal shared care protocols. Palliative care services are limited and general cardiologists rarely perform 6-minute walk tests (6MWT) or quality of life assessments. People with PAH-CHD are often undertreated, with 39% of respondents reporting that fewer than 25% of these patients were receiving PAH-specific therapies. CONCLUSIONS: The survey revealed gaps and inconsistencies in the management of patients with PAH-CHD therefore patient-specific guidance is needed for many of these aspects. PMID- 29191505 TI - Predictors of Frequent Readmissions in Patients With Heart Failure. AB - BACKGROUND: Patients with heart failure (HF) have a high incidence of hospital readmissions. However risk models that explore predictors of a single readmission may be less useful at identifying the patients with frequent readmissions who contribute to a disproportionately large proportion of morbidity and health care costs. METHODS: A total of 6252 patients enrolled in the Management of Cardiac Failure Program (MACARF) in Northern Sydney Area Hospitals between 1998 and 2015 were randomly divided into derivation and validation cohorts to create and test a risk model for predictors of >=2 readmissions or death within 1year of initial hospitalisation for HF. RESULTS: Multivariate predictors of frequent (>=2) readmissions or death were a history of ischaemic heart disease and chronic kidney disease, being unmarried, having anaemia, low serum albumin, elevated creatinine, prolonged hospital stay (>7 days), and not receiving beta blockers on discharge. Event rates increased with a higher risk score (p<0.001) and the prediction was similar in the validation and derivation cohorts (p=0.588). The C statistic was 0.65. CONCLUSIONS: Our risk score may assist in focussing health care resources and interventions by identifying the subset of HF patients at increased risk for a disproportionately high burden of disease. PMID- 29191506 TI - A Practical Guide for Fractional Flow Reserve Guided Revascularisation. AB - The presence and extent of myocardial ischaemia is a major determinant of prognosis and benefit from revascularisation in patients with stable coronary artery disease. Fractional Flow Reserve (FFR) is accepted as the reference standard for invasive assessment of ischaemia. Its ability to detect lesion specific ischaemia makes it a useful test in a wide range of patient and lesion subsets, with FFR guided intervention improving clinical outcomes and reducing health care costs compared to assessment with coronary angiography alone. This article will review the basic principles in FFR, practical tips in FFR guided revascularisation and the role of emerging non-hyperaemic indices of ischaemia. PMID- 29191508 TI - In vivo performance of freeze-dried decellularized pulmonary heart valve allo- and xenografts orthotopically implanted into juvenile sheep. AB - : The decellularization of biological tissues decreases immunogenicity, allows repopulation with cells, and may lead to improved long-term performance after implantation. Freeze drying these tissues would ensure off-the-shelf availability, save storage costs, and facilitates easy transport. This study evaluates the in vivo performance of freeze-dried decellularized heart valves in juvenile sheep. TritonX-100 and sodium dodecylsulfate decellularized ovine and porcine pulmonary valves (PV) were freeze-dried in a lyoprotectant sucrose solution. After rehydration for 24 h, valves were implanted into the PV position in sheep as allografts (fdOPV) and xenografts (fdPPV), while fresh dezellularized ovine grafts (frOPV) were implanted as controls. Functional assessment was performed by transesophageal echocardiography at implantation and at explantation six months later. Explanted grafts were analysed histologically to assess the matrix, and immunofluorescence stains were used to identify the repopulating cells. Although the graft diameters and orifice areas increased, good function was maintained, except for one insufficient, strongly deteriorated frOPV. Cells which were positive for either endothelial or interstitial markers were found in all grafts. In fdPPV, immune-reactive cells were also found. Our findings suggest that freeze-drying does not alter the early hemodynamic performance and repopulation potential of decellularized grafts in vivo, even in the challenging xenogeneic situation. Despite evidence of an immunological reaction for the xenogenic valves, good early functionalities were achieved. STATEMENT OF SIGNIFICANCE: Decellularized allogeneic heart valves show excellent results as evident from large animal experiments and clinical trials. However, a long-term storing method is needed for an optimal use of this limited resource in the clinical setting, where an optimized matching of graft and recipient is requested. As demonstrated in this study, freeze-dried and freshly decellularized grafts reveal equally good results after implantation in the juvenile sheep concerning function and repopulation with recipients' cells. Thus, freeze-drying arises as a promising method to extend the shelf-life of valvular grafts compared to those stored in antibiotic-solution as currently practised. PMID- 29191507 TI - Viscoelastic properties of human pancreatic tumors and in vitro constructs to mimic mechanical properties. AB - : Pancreatic ductal adenocarcinoma (PDAC) is almost universally fatal, in large part due to a protective fibrotic barrier generated by tumor-associated stromal (TAS) cells. This barrier is thought to promote cancer cell survival and confounds attempts to develop effective therapies. We present a 3D in vitro system that replicates the mechanical properties of the PDAC microenvironment, representing an invaluable tool for understanding the biology of the disease. Mesoscale indentation quantified viscoelastic metrics of resected malignant tumors, inflamed chronic pancreatitis regions, and histologically normal tissue. Both pancreatitis (2.15 +/- 0.41 kPa, Mean +/- SD) and tumors (5.46 +/- 3.18 kPa) exhibit higher Steady-State Modulus (SSM) than normal tissue (1.06 +/- 0.25 kPa; p < .005). The average viscosity of pancreatitis samples (63.2 +/- 26.7 kPa.s) is significantly lower than that of both normal tissue (252 +/- 134 kPa.s) and tumors (349 +/- 222 kPa.s; p < .005). To mimic this remodeling behavior, PDAC and TAS cells were isolated from human PDAC tumors. Conditioned medium from PDAC cells was used to culture TAS-embedded collagen hydrogels. After 7 days, TAS embedded gels in control medium reached SSM (1.45 +/- 0.12 kPa) near normal pancreas, while gels maintained with conditioned medium achieved higher SSM (3.38 +/- 0.146 kPa) consistent with tumors. Taken together, we have demonstrated an in vitro system that recapitulates in vivo stiffening of PDAC tumors. In addition, our quantification of viscoelastic properties suggests that elastography algorithms incorporating viscosity may be able to more accurately distinguish between pancreatic cancer and pancreatitis. STATEMENT OF SIGNIFICANCE: Understanding tumor-stroma crosstalk in pancreatic ductal adenocarcinoma (PDAC) is challenged by a lack of stroma-mimicking model systems. To design appropriate models, pancreatic tissue must be characterized with a method capable of evaluating in vitro models as well. Our indentation-based characterization tool quantified the distinct viscoelastic signatures of inflamed resections from pancreatitis, tumors from PDAC, and otherwise normal tissue to inform development of mechanically appropriate engineered tissues and scaffolds. We also made progress toward a 3D in vitro system that recapitulates mechanical properties of tumors. Our in vitro model of stromal cells in collagen and complementary characterization system can be used to investigate mechanisms of cancer-stroma crosstalk in PDAC and to propose and test innovative therapies. PMID- 29191509 TI - Cavitation nucleation in gelatin: Experiment and mechanism. AB - : Dynamic cavitation in soft materials is becoming increasingly relevant due to emerging medical implications such as the potential of cavitation-induced brain injury or cavitation created by therapeutic medical devices. However, the current understanding of dynamic cavitation in soft materials is still very limited, mainly due to lack of robust experimental techniques. To experimentally characterize cavitation nucleation under dynamic loading, we utilize a recently developed experimental instrument, the integrated drop tower system. This technique allows quantitative measurements of the critical acceleration (acr) that corresponds to cavitation nucleation while concurrently visualizing time evolution of cavitation. Our experimental results reveal that acr increases with increasing concentration of gelatin in pure water. Interestingly, we have observed the distinctive transition from a sharp increase (pure water to 1% gelatin) to a much slower rate of increase (~10* slower) between 1% and 7.5% gelatin. Theoretical cavitation criterion predicts the general trend of increasing acr, but fails to explain the transition rates. As a likely mechanism, we consider concentration-dependent material properties and non-spherical cavitation nucleation sites, represented by pre-existing bubbles in gels, due to possible interplay between gelatin molecules and nucleation sites. This analysis shows that cavitation nucleation is very sensitive to the initial configuration of a bubble, i.e., a non-spherical bubble can significantly increase acr. This conclusion matches well with the experimentally observed liquid-to-gel transition in the critical acceleration for cavitation nucleation. STATEMENT OF SIGNIFICANCE: From a medical standpoint, understanding dynamic cavitation within soft materials, i.e., tissues, is important as there are both potential injury implications (blast-induced cavitation within the brain) as well as treatments utilizing the phenomena (lithotripsy). In this regard, the main results of the present work are (1) quantitative characterization of cavitation nucleation in gelatin samples as a function of gel concentration utilizing well-controlled mechanical impacts and (2) mechanistic understanding of complex coupling between cavitation and liquid-/solid-like material properties of gel. The new capabilities of testing soft gels, which can be tuned to mimic material properties of target organs, at high loading rate conditions and accurately predicting their cavitation behavior are an important step towards developing reliable cavitation criteria in the scope of their biomedical applications. PMID- 29191510 TI - Transplantation of human amnion prevents recurring adhesions and ameliorates fibrosis in a rat model of sciatic nerve scarring. AB - : Peripheral nerve fibrosis and painful adhesions are common, recurring pathological sequelae following injury. In this study, vital human amnion (hAM), an increasingly interesting biomaterial for regenerative medicine, was investigated as a novel therapy. hAM was first analyzed in vitro regarding its anti-adhesive characteristics. Then, the reflected region of hAM which was identified as more suitable, was transplanted into female Sprague Dawley rats with recurring sciatic nerve scarring (n = 24) and compared with untreated controls (n = 30) at one, four and twelve weeks. Immune response and fibrosis were investigated by (immuno)histochemical analysis. Nerve structure was examined and function determined using electrophysiology and gait analysis. Here we identified strongly reduced adhesions in the hAM-treated rats, displaying a significant difference at four weeks post transplantation compared to untreated controls (p = .0052). This correlated with the in vitro cell attachment test on hAM explants, which demonstrated a distinctly limited ability of fibroblasts to adhere to amniotic epithelial cells. Upon hAM transplantation, significantly less intraneural fibrosis was identified at the later time points. Moreover, hAM treated rats exhibited a significantly higher sciatic functional index (SFI) after four weeks compared to controls (p < .05), which indicated a potentially pro-regenerative effect of hAM. As a possible explanation, an impact of hAM on the endogenous immune response, including T cell and macrophage subsets, was indicated. We conclude that hAM is strongly effective against recurring nerve scarring and induces an anti-fibrotic and pro-regenerative effect, making it highly promising for treating adhesion-related disorders. STATEMENT OF SIGNIFICANCE: Abnormal fibrotic bonding of tissues, frequently involving peripheral nerves, affects millions of people worldwide. These so-called adhesions usually cause severe pain and drastically reduce quality of life. To date, no adequate treatment exists and none is routinely used in the clinical practice. In this study, vital human amnion, the innermost of the fetal membranes, was transplanted in a rat model of peripheral nerve scarring and recurring adhesions as novel therapeutic approach. Amniotic cells have already demonstrated to feature stem-cell like properties and produce pro-regenerative factors, which makes the amnion an increasingly promising biomaterial for regenerative medicine. We identified that its transplantation was very effective against peripheral nerve scarring and distinctly reduced recurring adhesions. Moreover, we identified a pro-regenerative effect. This study showed that the amnion is a highly promising novel therapeutic approach for adhesion-related disorders. PMID- 29191511 TI - The Role of Inhibition in Avoiding Distraction by Salient Stimuli. AB - Researchers have long debated whether salient stimuli can involuntarily 'capture' visual attention. We review here evidence for a recently discovered inhibitory mechanism that may help to resolve this debate. This evidence suggests that salient stimuli naturally attempt to capture attention, but capture can be avoided if the salient stimulus is suppressed before it captures attention. Importantly, the suppression process can be more or less effective as a result of changing task demands or lapses in cognitive control. Converging evidence for the existence of this suppression mechanism comes from multiple sources, including psychophysics, eye-tracking, and event-related potentials (ERPs). We conclude that the evidence for suppression is strong, but future research will need to explore the nature and limits of this mechanism. PMID- 29191512 TI - A unique respiratory adaptation in Drosophila independent of supercomplex formation. AB - Large assemblies of respiratory chain complexes, known as supercomplexes, are present in the mitochondrial membrane in mammals and yeast, as well as in some bacterial membranes. The formation of supercomplexes is thought to contribute to efficient electron transfer, stabilization of each enzyme complex, and inhibition of reactive oxygen species (ROS) generation. In this study, mitochondria from various organisms were solubilized with digitonin, and then the solubilized complexes were separated by blue native PAGE (BN-PAGE). The results revealed a supercomplex consisting of complexes I, III, and IV in mitochondria from bovine and porcine heart, and a supercomplex consisting primarily of complexes I and III in mitochondria from mouse heart and liver. However, supercomplexes were barely detectable in Drosophila flight-muscle mitochondria, and only dimeric complex V was present. Drosophila mitochondria exhibited the highest rates of oxygen consumption and NADH oxidation, and the concentrations of the electron carriers, cytochrome c and quinone were higher than in other species. Respiratory chain complexes were tightly packed in the mitochondrial membrane containing abundant phosphatidylethanolamine with the fatty acid palmitoleic acid (C16:1), which is relatively high oxidation-resistant as compared to poly-unsaturated fatty acid. These properties presumably allow efficient electron transfer in Drosophila. These findings reveal the existence of a new mechanism of biological adaptation independent of supercomplex formation. PMID- 29191513 TI - International consensus on definition and criteria of borderline resectable pancreatic ductal adenocarcinoma 2017. AB - This statement was developed to promote international consensus on the definition of borderline resectable pancreatic ductal adenocarcinoma (BR-PDAC) which was adopted by the National Comprehensive Cancer Network (NCCN) in 2006, but which has changed yearly and become more complicated. Based on a symposium held during the 20th meeting of the International Association of Pancreatology (IAP) in Sendai, Japan, in 2016, the presenters sought consensus on issues related to BR PDAC. We defined patients with BR-PDAC according to the three distinct dimensions: anatomical (A), biological (B), and conditional (C). Anatomic factors include tumor contact with the superior mesenteric artery and/or celiac artery of less than 180 degrees without showing stenosis or deformity, tumor contact with the common hepatic artery without showing tumor contact with the proper hepatic artery and/or celiac artery, and tumor contact with the superior mesenteric vein and/or portal vein including bilateral narrowing or occlusion without extending beyond the inferior border of the duodenum. Biological factors include potentially resectable disease based on anatomic criteria but with clinical findings suspicious for (but unproven) distant metastases or regional lymph nodes metastases diagnosed by biopsy or positron emission tomography-computed tomography. This also includes a serum carbohydrate antigen (CA) 19-9 level more than 500 units/ml. Conditional factors include the patients with potentially resectable disease based on anatomic and biologic criteria and with Eastern Cooperative Oncology Group (ECOG) performance status of 2 or more. The definition of BR-PDAC requires one or more positive dimensions (e.g. A, B, C, AB, AC, BC or ABC). The present definition acknowledges that resectability is not just about the anatomic relationship between the tumor and vessels, but that biological and conditional dimensions are also important. The aim in presenting this consensus definition is also to highlight issues which remain controversial and require further research. PMID- 29191515 TI - Mapping the spatial distribution of Aedes aegypti and Aedes albopictus. AB - Mosquito-borne infectious diseases, such as Rift Valley fever, Dengue, Chikungunya and Zika, have caused mass human death with the transnational expansion fueled by economic globalization. Simulating the distribution of the disease vectors is of great importance in formulating public health planning and disease control strategies. In the present study, we simulated the global distribution of Aedes aegypti and Aedes albopictus at a 5*5km spatial resolution with high-dimensional multidisciplinary datasets and machine learning methods Three relatively popular and robust machine learning models, including support vector machine (SVM), gradient boosting machine (GBM) and random forest (RF), were used. During the fine-tuning process based on training datasets of A. aegypti and A. albopictus, RF models achieved the highest performance with an area under the curve (AUC) of 0.973 and 0.974, respectively, followed by GBM (AUC of 0.971 and 0.972, respectively) and SVM (AUC of 0.963 and 0.964, respectively) models. The simulation difference between RF and GBM models was not statistically significant (p>0.05) based on the validation datasets, whereas statistically significant differences (p<0.05) were observed for RF and GBM simulations compared with SVM simulations. From the simulated maps derived from RF models, we observed that the distribution of A. albopictus was wider than that of A. aegypti along a latitudinal gradient. The discriminatory power of each factor in simulating the global distribution of the two species was also analyzed. Our results provided fundamental information for further study on disease transmission simulation and risk assessment. PMID- 29191514 TI - Perceived neighborhood characteristics predict severity and emotional response to daily stressors. AB - RATIONALE: Neighborhood characteristics may influence health and well-being outcomes through stressors in daily life. OBJECTIVES: This study tested whether a varied set of perceived characteristics of neighborhood (i.e., social cohesion, safety, aesthetic quality, violence) predicted stressor frequency and severity as well as negative emotional responses to stressors. We predicted greater reported cohesion and safety and less violence would be associated with less frequent stressor exposure and severity and less intense negative affect following stressors; we conducted subsequent tests of neighborhood aesthetic quality as a predictor. METHODS: Participants (n = 233, age 25-65 years) were residents in a socio-economically, racially, and ethnically diverse zip code in Bronx, New York, most who participated in the Effects of Stress on Cognitive Aging, Physiology and Emotion study between 2012 and 2013. They provided demographic information and neighborhood ratings, then participated in the EMA protocol in which they completed brief smartphone surveys of current negative affect and stressor exposure, severity, and recency, five times daily for 14 days. RESULTS: No coded neighborhood characteristic was related to the frequency of stressors. Individuals who reported greater neighborhood violence, however, rated their stressors as more severe. Individuals rating their neighborhood lower in safety or aesthetic quality, or higher in violence, had greater negative affect following stressors. CONCLUSION: Even among people living within the same zip code, individual differences in perceptions of neighborhood predict how stressful they appraised stressors in daily life to be and how much negative affect they reported following stressors. PMID- 29191517 TI - Potential risk of a liver fluke Opisthorchis viverrini infection brought by immigrants from prevalent areas: A case study in the lower Northern Thailand. AB - Considering the long lifespan of the liver fluke Opisthorchis viverrini, human mobility from prevalent regions to other neighboring areas has the possibility to disperse carriers and complicate the opisthorchiasis problem. To evaluate this, mass screening of the fluke infection was conducted in nine communities of lower Northern Thailand, combined with a questionnaire survey to distinguish the participant's origin. The liver fluke infection was found in 70 individuals (7.2%) of the examined 971 stool samples from seven communities, with light intensity providing small numbers of eggs in the examined stool. Prevalence in the positive communities varied from 2.1% to 28.7%. As a result of generalized linear mixed models fitting, regional origin and raw-fish eating habits were stably selected as variables affecting the parasite infection while occupation and educational background were secondary ones. Majority of the infected cases (64.3%) were found from the immigrants of northeastern Thailand (the fluke prevalent region), providing 2.28-2.42 times higher infectious risk on average against the local residents. Daily consumption of raw fish averaged a 3.12-3.60 times higher risk compared to those with no raw-fish eating habit. Our findings suggest that people's origin and moving history deserve further attentions in health promotion programs including education for safe eating. PMID- 29191516 TI - Sero-prevalence of Bovine Brucellosis and associated risk factors in mbeya region, Southern highlands of Tanzania. AB - A cross-sectional study was conducted to establish the seroprevalence of brucellosis and associated risk factors in indigenous and exotic breeds of cattle from 178 farms in Mbeya region. A total of 1211 cattle (929exotic cattle from 108 commercial farms and 282 indigenous cattle from 70 traditional farms) were tested for Brucella antibodies using the Rose Bengal Plate Test (RBPT) and competitive Enzyme Linked Immunosorbent Assay (c-ELISA) as screening and confirmatory tests, respectively. The overall animal-level seroprevalence was 9.3%; 11.3% (95% CI: 9.4-13.5) in indigenous cattle and 2.8% (95% CI:1.4-5.6) in exotic cattle. Further, the overall herd level seroprevalence was 32.0%; 50.5% (95% CI: 40.9 59.9) in indigenous cattle and 4.2% (95% CI: 1.3-12.4) in exotic cattle. Infections were higher in cattle aged 6-10 years old, (39.8%; 95% CI: 31.2-49.1) followed by those aged 1-5 years (5.8%; 95% CI: 4.8-6.6) and 11-15years old (2.7%; 95% CI: 0.8-8). When compared to cattle sampled from herds size of 1-50, those sampled from the herd sizes of 51-100 and 101-150 had higher odds of brucellosis seropositivity [(OR=3.6, CI: 1.76-7.16, p<0.001) and (OR=3.0, CI: 1.09-8.04, p=0.033). The odds of seropositivity in animals which calved on pasture was 3.0 (CI: 1.1-7.8, p=0.028) compared to those that calved at home. Brucella seroprevalence was also observed to vary according to districts, with Mbarari district recording the highest (45.4%). It is evident from the study that Brucellosis is present in Mbarari, Mbeya and Momba districts of Mbeya Region. The findings of this study provide some baseline data that could contribute to the design and implementation of brucellosis control measures in the study areas. PMID- 29191518 TI - New paleoparasitological investigations from the pre-inca to hispanic contact period in northern Chile. AB - Paleoparasitological studies have demonstrated that changes in environment or culture are reflected in the patterns of parasitic infection diseases in populations worldwide. The advent of agriculture and animal domestication, with its accompanying reduction in human mobility and expanding population involves changes in or emergence of, parasites, the so-called first epidemiological transition. Cultural processes related to territory occupation contribute to both loss and acquisition of parasites. The archaeological site Lluta 57 in the Lluta Valley, Chile, provides a chronology of the transition from the pre-Inca or Late Intermediate Period (LIP), through the Late or Inca Period (LP), to the Hispanic Contact Period (HCP), providing the possibility of evaluating this epidemiological transition. The aim of this study was to conduct a paleoparasitological investigation of to gain insight into the dynamics of parasitism in Lluta people throughout the Inca expansion. Fourteen human coprolites from the three periods were rehydrated, submitted to spontaneous sedimentation, and examined by light microscopy for the presence of intestinal parasite eggs, pollen grains, and micro-remains. Eggs of four parasites: Enterobius vermicularis, Trichostrongylus sp., Trichuris sp., and Eimeria macusaniensis were recovered. Frequency, diversity, and number of parasite eggs per sample increased over the studied time period. Trichostrongylus sp. and E. macusaniensis were recorded in the region for the first time. Enterobius vermicularis eggs, absent in the LIP, were present as a hyper-infection in LP. The presence of E. macusaniensis is likely related to exploitation of llamas, which were used for food and transport and as sacrificial offerings. The paleobotanical analysis revealed ten families of pollen grains, as well as phytoliths and floral remains. In contrast to parasitological results, a diachronic pattern was not detected. Evolution of the settlements, with the advent of larger, more densely populated, villages, could have influenced the emergence and intensification of transmission of parasites in the region. The study showed that the Inca expansion influenced host-parasite-environment relationships in the Lluta Valley.

AB - The aim of this study was to develop a novel controlled ionic gelation strategy for chitosan nanoparticle preparation to avoid particle aggregation tendency associated with conventional ionic gelation process. In this study inclusion complexation behaviour of sodium tripolyphosphate (TPP) with beta cyclodextrin (beta-CD) has been investigated. The TPP-beta-CD inclusion complex was characterized by FT-IR, XRD and DSC techniques. The complexation behaviour was also investigated by molecular docking study. The results showed that the TPP molecule formed inclusion complex with beta-CD. Further, TPP-beta-CD inclusion complex was used to prepare chitosan nanoparticles. The chitosan nanoparticles based on TPP-beta-CD inclusion complex had smaller size of 104.2nm+/-0.608, good PDI value of 0.346+/-0.016 and acceptable zeta potential of +27.33mV+/-0.416. The surface characteristics of chitosan nanoparticles were also observed with transmission electron microscopy. Results indicates that TPP-beta-CD inclusion complex can be used for the formation of chitosan nanoparticles with smaller and more uniform particle size in comparison to conventional TPP based chitosan nanoparticles. PMID- 29191519 TI - Opisthorchis felineus infection prevalence in Western Siberia: A review of Russian literature. AB - In this study we reviewed Russian scientific literature (scientific publications, book chapters, monographs) published between 1 January 1979 and 31 August 2015 from two sources: Main database of the Russian Scientific Electronic Library (eLIBRARY, http://elibrary.ru/), and the Scientific Medical Library of Siberian State Medical University (http://medlib.tomsk.ru/). Specifically, the review details the infection prevalence of Opisthorchis felineus (O. felineus) in Western Siberia, Russian Federation. From the primary key words screening, 1591 records were identified from which 32 Russian-language publications were relevant. The lowest O. felineus infection rate of 0.4% was reported in Tatarstan Republic, and the highest reached 83.9% in the Khanty-Mansiysk Autonomous Okrug. The infection prevalence was lower in children than in adults and increased with age. O. felineus infection was detected more often in indigenous population than in migrants. Infection intensity in western regions (Permskaya, Bryanskaya Oblast) was low and varied from 15 to 336 eggs per gram stool (epg), while in endemic regions it reached more than 2000 epg. In some settlements the mean intensity infection was 5234 epg. The high rates of intensity were registered in regions with a high prevalence of infection. Based on obtained data, a map of O. felineus infection prevalence in Western Siberia was developed. After mapping the results, the highest prevalence was detected in Tyumenskaya Oblast with over 60%, while the Tomskaya Oblast had the lowest prevalence at fewer than 19.0%. Khanty Mansiysk Autonomus Okrug, Altaiskii Krai, Novosibirskaya Oblast and Omskaya Oblast had an average level of O. felineus infection of 20-39%. According to the results of the review, Western Siberia must be considered as highly endemic region for opisthorchiasis in the Russian Federation. The development of a control program specific for the Russian community is warranted. PMID- 29191521 TI - The possibility of obtaining marketing authorization of orphan pharmaceutical compounding preparations: 3,4-DAP for Lambert-Eaton Myasthenic Syndrome. AB - BACKGROUND: Pharmaceutical compounding preparations, produced by (hospital) pharmacies, usually do not have marketing authorization. As a consequence, some of these pharmaceutical compounding preparations can be picked-up by a pharmaceutical company to obtain marketing authorization, often leading to price increases. An example is the 3,4-diaminopyridine slow release (3,4-DAP SR) tablets for Lambert-Eaton Myasthenic Syndrome (LEMS). In 2009 marketing authorization was given for the commercial immediate release phosphate salt of the drug, including a fifty-fold price increase compared to the pharmaceutical compounding preparation. Obtaining marketing authorization for 3,4-DAP SR by academia might have been a solution to prevent this price increase. To determine whether the available data of a pharmaceutical compounding preparation with long term experience in regular care are adequate to obtain marketing authorization, 3,4-DAP SR is used as a case study. METHODS: A retrospective qualitative case study was performed. Initially, document analysis was executed by collecting the required data for marketing authorization in general and whether data of Firdapse(r) and 3,4-DAP SR met these requirements. Secondly, the (non-) available data of the two formulations were compared with each other to determine the differences in availability. RESULTS: At the time of approval, almost all data were available for both Firdapse(r) and 3,4-DAP SR. Conversely, much of the data used for the approval of Firdapse(r) originated from the 3,4-DAP immediate release (3,4-DAP IR) formulation. Only two bioequivalence studies and one pharmacology safety study was performed with Firdapse(r) before marketing authorization application. CONCLUSIONS: In conclusion, at time Firdapse(r) obtained approval, the data available did not differ substantially from 3,4-DAP SR, indicating that approval with 3,4-DAP SR would have been possible. We make a plea for approval of orphan medicinal products developed and manufactured by academic institutions as to keep utilization of these products affordable. PMID- 29191522 TI - Cyclodextrin-siRNA conjugates as versatile gene silencing agents. AB - Functional siRNAs (luciferase and PLK1) have been conjugated to beta-cyclodextrin and the ability of the conjugates to retain gene knockdown activity has been assessed by delivery to cancer cell lines using various formulations. Initially two formulations used complexation with polycations, namely Lipofectamine 2000 and an amphiphilic polycationic cyclodextrin. Gene knockdown results for human glioblastoma cells (U87) and prostate cancer cells (PC3, DU145) showed that conjugation to the cyclodextrin did not reduce gene silencing by the RNA. A third mode of delivery involved formation of targeted nanoparticles in which the conjugate was first complexed with adamantyl-PEG-ligands (targeting ligand RVG peptide or dianisamide) by adamantyl inclusion in the cyclodextrin cavities of the conjugates, followed by charge neutralisation with the cationic polymer chitosan. Enhanced knockdown was achieved by these ligand-targeted formulations. In summary, while this study illustrated the gene silencing efficacy of a simple cyclodextrin-siRNA conjugate it is envisaged that future studies will explore the use of conjugates with a modified cyclodextrin which would be self-delivering. Detailed data such as stability, lysosomal escape etc. will then be reported for each conjugate, since this will be appropriate for conjugates which are intended to exploit, rather than merely demonstrate, the concept. The present paper was intended to demonstrate the viability and generality of this novel concept.

PMID- 29191525 TI - Apixaban in the prevention of stroke and systemic embolism in patients with non valvular atrial fibrillation in France: Rationale and design of the PAROS cross sectional study. AB - BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia worldwide, and its prevalence is expected to increase with population ageing. The use of vitamin K antagonists (VKAs) for the prevention of stroke and/or systemic embolism in patients with non-valvular atrial fibrillation (NVAF) was recently challenged by non-VKA oral anticoagulants (NOACs), demonstrating a favourable risk-benefit profile, with reductions in stroke, intracranial haemorrhage and mortality, similar major bleeding, but increased gastrointestinal bleeding. Nevertheless, data on their use in a "real-life" setting are scarce for France. AIMS: To compare the characteristics of patients with AF newly anticoagulated with either VKAs or NOACs, to describe the reasons for discontinuing the previous anticoagulant strategy and/or choosing the newly initiated anticoagulant treatment, and to precisely describe the prescriptions of patients newly initiated with apixaban. METHODS: This is a nationwide multicentre non interventional cross-sectional study conducted in patients with AF by a representative stratified sample of cardiologists in France. Over a 12-month accrual period, consecutive patients aged >=18 years with NVAF, for whom anticoagulant treatment (VKAs or NOACs) has been initiated within the last three months before the index consultation, will be included. The primary outcome will be the comparison of anticoagulant-naive patient characteristics, co-morbidities and treatment history among the anticoagulant subgroups. Secondary endpoints will include a description of the reasons for discontinuing the previous anticoagulant strategy and/or for initiating and choosing the newly initiated anticoagulant treatment, as well as the prescription conditions of apixaban. CONCLUSION: The PAROS study will provide real-life data on the characteristics of NVAF patients and their anticoagulant prescription in France. PMID- 29191526 TI - Clinical Application of an Open-Source 3D Volume Rendering Software to Neurosurgical Approaches. AB - BACKGROUND: Preoperative recognition of the anatomic individualities of each patient can help to achieve more precise and less invasive approaches. It also may help to anticipate potential complications and intraoperative difficulties. Here we describe the use, accuracy, and precision of a free tool for planning microsurgical approaches using 3-dimensional (3D) reconstructions from magnetic resonance imaging (MRI). METHODS: We used the 3D volume rendering tool of a free open-source software program for 3D reconstruction of images of surgical sites obtained by MRI volumetric acquisition. We recorded anatomic reference points, such as the sulcus and gyrus, and vascularization patterns for intraoperative localization of lesions. Lesion locations were confirmed during surgery by intraoperative ultrasound and/or electrocorticography and later by postoperative MRI. RESULTS: Between August 2015 and September 2016, a total of 23 surgeries were performed using this technique for 9 low-grade gliomas, 7 high-grade gliomas, 4 cortical dysplasias, and 3 arteriovenous malformations. The technique helped delineate lesions with an overall accuracy of 2.6 +/- 1.0 mm. 3D reconstructions were successfully performed in all patients, and images showed sulcus, gyrus, and venous patterns corresponding to the intraoperative images. All lesion areas were confirmed both intraoperatively and at the postoperative evaluation. CONCLUSIONS: With the technique described herein, it was possible to successfully perform 3D reconstruction of the cortical surface. This reconstruction tool may serve as an adjunct to neuronavigation systems or may be used alone when such a system is unavailable. PMID- 29191527 TI - Optic Nerve Meningioma Mimicking Cavernous Hemangioma. AB - A 38-year-old woman presented with rapidly worsening, painless right monocular vision loss. An examination revealed a visual acuity of 1.4/10 and a central scotoma in the right eye. The orbital magnetic resonance imaging (MRI) showed a well-delineated ovoid intraconal mass of the right eye, hyperintense on T2 weighted MRI with homogenous enhancement after contrast injection. The mass abutted and displaced the optic nerve. A diagnosis of cavernous hemangioma was evoked, which is the most common benign adult orbital mass with these MRI features. A biopsy was performed, and the histopathologic examination yielded a diagnosis of optic nerve sheath meningioma based on a positive antiprogesterone receptor antibody immunostaining. Our case highlights the problem with establishing a specific pathologic diagnosis based on MRI alone, even though the morphologic aspect is evocative. It is recommended to always conduct a histopathologic examination before establishing a specific diagnosis as pathology remains the gold standard, especially when the course of action or treatment may change, as in our case. PMID- 29191528 TI - Web Vessels: Literature Review and Neurointerventional Management. AB - OBJECTIVE: The aim of this study was to describe 27 patients with 32 web vessels (WVs) from our practice and provide a review of the literature regarding imaging diagnostics, clinical presentation, and treatment of WVs. METHODS: A MEDLINE search was performed using combinations of the following terms: "stroke in young adults," "web," "recurrent stroke," "diaphragm-like," "atypical fibromuscular hyperplasia," "atypical fibromuscular dysplasia," "septal fibromuscular dysplasia," "septa," "diaphragms," "pseudovalvular folds," and "carotid diaphragm." Our series was added in this review. RESULTS: According to location, there were 88 carotid WVs (91.66%), 7 vertebral WVs (7.3%), and 1 subclavian WV (1.04%). According to clinical presentation, the reported WVs caused stroke in 81 cases (84.38%). Treatment was supportive care in 46 cases (47.91%), surgery in 33 cases (35.41%), and an endovascular procedure through angioplasty and stenting in 17 cases (17.7%). Variables such as age (P = 0.7565), sex (P = 0.6912), and location (P = 0.7993) were not shown to be risk factors for stroke in these patients. CONCLUSIONS: Although few cases have been reported in the literature, the stroke rate in patients with WVs is high. Endovascular treatment is presented as an effective form of treatment with no associated morbidities or recurrences of ischemic events. PMID- 29191529 TI - Health-Related Quality of Life and Posttraumatic Growth in Low-Grade Gliomas in China: A Prospective Study. AB - OBJECTIVE: The present study aimed to describe the quality of life (QoL) changes of survivors of low-grade gliomas (LGGs) 1 year after surgery and to identify determinants of QoL with an emphasis on the role of perceived posttraumatic growth (PTG). We also tried to examine the linear and quadratic relationship between QoL and PTG. METHODS: Two hundred sixty participants were included in the final data analysis. The Chinese version of posttraumatic growth inventory and the Functional Assessment of Cancer Therapy-Brain scale were used to measure PTG and QoL. Hierarchical linear models were fitted to explore the individual time trajectories in change of QoL and examine the relationship between demographics, clinical features, PTG, and QoL. RESULTS: All dimensions of QoL and PTG increased over time except physical well-being, social well-being in QoL, and new possibilities in PTG. Time, PTG score, insurance, socioeconomic status, and right hemisphere tumor position were positive predictors of QoL. Seizure and depression negatively predicted QoL. The quadratic of PTG predicted QoL; however, the coefficient of quadratic PTG approached zero. CONCLUSIONS: In general, PTG and QoL increased over time. Perceived PTG could significantly predict QoL of LGGs survivors 1 year after surgery. A quadratic relation between PTG and QoL was not found. Although our data suggested that the growth of QoL may vary across different patients, there were only 2 time points in this study. Future studies should set more time points to examine this relationship. PMID- 29191530 TI - Acute Bilateral Isolated Foot Drop: Changing the Paradigm in Management of Degenerative Spine Surgery with Percutaneous Endoscopy. AB - BACKGROUND: Acute bilateral isolated foot drop due to lumbar disk prolapse with canal stenosis is rare with only 3 cases reported in literature. Our patient was managed using the percutaneous full endoscopic technique. This is mainly to highlight the ease of access and patient outcome with preoperative and postoperative images to support our minimally invasive treatment for this rare condition. CASE DESCRIPTION: A 46-year-old male presented with sudden-onset severe back pain with bilateral foot drop. Clinical examination showed a bilateral L5 radiculopathy with normal perianal sensation. Investigations excluded other causes of bilateral foot drop. A magnetic resonance imaging scan showed disk herniation at the right L4-L5 (inferior migrated) and L5-S1 level (paracentral and extraforaminal) with spinal canal stenosis at the L2-L3 and L5 S1 levels due to ligamentum flavum hypertrophy. The patient underwent percutaneous endoscopic stenosis lumbar decompression at the L2-L3 and L5-S1 level. At the right L4-L5, L5-S1 level, transforaminal endoscopic diskectomy was done using the conventional percutaneous approach. The inferior migrated disk of the L4-L5 level was removed using a left L5-S1 contralateral approach. The patient recovered with favorable outcome and added benefits of minimally invasive surgery. CONCLUSION: Lumbar disk prolapse with canal stenosis should be considered in patients presenting with bilateral isolated foot drop. To our best knowledge, this is the first report of percutaneous endoscopic treatment to address multiple-lumbar-level pathology for this rare condition of acute bilateral isolated foot drop. PMID- 29191531 TI - Utility of Retrograde Amnesia Assessment Alone, Compared with Anterograde Amnesia Assessment in Determining Recovery After Traumatic Brain Injury: Prospective Cohort Study. AB - BACKGROUND: Posttraumatic amnesia (PTA) after traumatic brain injury (TBI) comprises anterograde amnesia (AA), disorientation, and retrograde amnesia (RA). However, RA is often neither assessed nor emphasized. A recent study demonstrated that although AA and disorientation were both present in non-TBI inpatients uniformly taking opioids, RA was absent. This suggests potentially significant utility with RA assessment alone since opioids are commonly prescribed post TBI. METHODS: We compared RA recovery with AA recovery in a prospective cohort post TBI. The Galveston Orientation and Amnesia Test (GOAT) represented a crude test for PTA (GOAT <75). AA was primarily assessed using the Westmead PTA Scale, and RA was assessed using the GOAT. All patients were prescribed oxycodone. RESULTS: Results were obtained (n = 31). While RA recovery coincided with a GOAT recovery in 19/31 (61%), AA recovery coincided with GOAT recovery in only 6/31 (19%), (chi2 = 11.5, P < 0.001). RA recovery preceded AA recovery in 15/31 (48%), while AA recovery preceded RA recovery in 7/31 (23%) (chi2 = 8.6, P = 0.003). Where RA recovery less frequently followed AA recovery, temporal lobe contusions were more frequent. RA recovery preceded/coincided with AA recovery in 100% of those who recovered when AA was defined as *3 consecutive 12/12 scores (as is current widespread practice). AA recovery typically followed RA recovery with minimal delay. CONCLUSIONS: In the presence of potential in-hospital confounders including opioids, RA recovered significantly sooner after TBI than AA and was predictive of imminent AA recovery. RA assessment alone therefore had significant and novel utility in post-TBI assessment. RA assessment should be routinely recorded in all PTA assessment. Given its simplicity and resilience to common confounders, RA assessment should also be incorporated into the Glasgow Coma Scale. PMID- 29191532 TI - The Incidence and Risk Factors of In-Stent Restenosis for Vertebrobasilar Artery Stenting. AB - BACKGROUND AND OBJECTIVES: In-stent restenosis (ISR) remains a challenge for vertebrobasilar artery stenting (VBAS). We aimed to investigate the incidence and risk factors of ISR. METHODS: This was a retrospective study. From July 28, 2005, to July 30, 2015, patients who received VBAS with an angiographic follow-up time of 6 to 12 months after surgery were enrolled. The clinical and angiographic issues were recorded and analyzed. RESULTS: In total, 283 patients with 335 stents were incorporated into the study. Vertebral ostial lesions accounted for 73.4% (246/335) of the lesions. During the follow-up period, 58 patients with 60 stents experienced ISR (>50%). Stepwise logistic regression analysis showed that the degree of residual stenosis, stent diameter, and alcohol consumption were independent predictors of ISR. CONCLUSIONS: Our study demonstrated the incidence and risk factors of ISR after VBAS. This retrospective study with the largest cohort to date provided insight into the occurrence of ISR after VBAS. PMID- 29191533 TI - Oncogenic Viruses in Skull Base Chordomas. AB - BACKGROUND: Chordomas are rare tumors assumed to derive from notochordal remnants. We believe that a molecular switch is responsible for their malignant behavior. The involvement of oncogenic viruses has not been studied, however. Thus, in the present study, we investigated the presence of oncogenic viruses in chordomas. METHODS: DNA and RNA from snap-frozen chordoma (n = 18) and chondrosarcoma (n = 15) specimens were isolated. Real-time PCR or RT-PCR was performed to assess the presence of multiple oncogenic viruses, including herpesviridea (herpes simplex virus [HSV]-1, HSV-2, Epstein-Barr virus [EBV], cytomegalovirus, human herpesvirus [HHV]- 6, HHV-7, and Kaposi's sarcoma associated herpesvirus), polyomaviridea (parvovirus B19 [PVB19], BK virus, JC virus, Simian virus 40, Merkel cell polyomavirus, human polyomavirus [HPyV]-6, and HPyV-7), papillomaviridae, and respiratory viruses. Immunohistochemistry (IHC) and in situ hybridization (ISH) were used to validate the positive results. RESULTS: PVB19 DNA was detected in 4 of 18 chordomas (22%) and in 1 of 15 chondrosarcomas (7%). IHC recognizing the VP2 capsid protein of PVB19 showed a positive cytoplasmic staining in 44% of the cases (14 of 32). HHV7 DNA was present in 6 of the 18 chordomas (33%). Genomic DNA of EBV was found in 22% of the samples; however, no positive results were found on ISH. None of the chordoma cases showed any presence of DNA from the remaining viruses. CONCLUSIONS: Viral involvement in the etiology of chordomas is likely, with PVB19 the most distinguishing. PMID- 29191534 TI - Microsurgical Clipping of a Giant Middle Cerebral Artery Aneurysm with Successful Postoperative Endovascular Mechanical Thrombectomy for Emergent Treatment of Large Vessel Occlusion. AB - BACKGROUND: Giant intracranial aneurysms (>25 mm) are uncommon. These lesions typically manifest clinically due to mass effect, acute hemorrhage, or thromboembolic events. To minimize the risk of poor clinical outcome, detailed operative planning and a consideration of all neurosurgical and endovascular techniques are essential before proceeding with microsurgical clipping of ruptured giant aneurysms. CASE DESCRIPTION: We describe a case involving a 15 year-old male with a ruptured giant middle cerebral artery aneurysm treated with microsurgical clipping. After clip application, poor distal flow was demonstrated intraoperatively, and emergent angiography demonstrated an M1 occlusion with thrombus. A salvage procedure using endovascular mechanical thrombectomy reestablished distal flow resulting in a good neurologic outcome. CONCLUSIONS: To our knowledge, this is the first case report to describe microsurgical clipping of an aneurysm followed by successful postoperative endovascular mechanical thrombectomy. PMID- 29191535 TI - What Should We Do for Those Hemifacial Spasm Patients Without Efficacy Following Microvascular Decompression: Expectation of Delayed Relief or Early Reoperation? AB - BACKGROUND: Although microvascular decompression (MVD) has been widely accepted as an effective treatment for hemifacial spasm (HFS), some patients may experience delayed relief instead of immediate improvement after the surgery. The need for and timing of repeat MVD has been controversial to date; thus, we conducted the present study with emphasis on those unrelieved patients. METHODS: Between January 2010 and December 2014, 3095 patients with idiopathic HFS were treated with MVD at XinHua Hospital, Shanghai Jiaotong University School of Medicine. Among these patients, 174 (5.6%) reported no symptom relief. Those patients without immediate relief were the focus of this study, and all were reevaluated at 2 years after MVD surgery. RESULTS: Among these 174 patients, 96 underwent redo MVD within 1 week of the first procedure (early MVD redo group), 19 underwent redo between 3 and 12 months after the first procedure (late MVD redo group), and 59 were observed (observation group). In the early redo MVD group, immediate improvement was reported by all patients except 1, who did not experience symptom relief until 3 months later. In the later redo MVD group, immediate symptom improvement was reported by 14 of 19 patients. By the end of the 2-year follow-up period, 1 recurrence occurred in the early redo MVD group, no changes occurred in the later MVD group, and 9 patients improved in the observation group. Ultimately, the final rates of symptom relief were 99.0% in the early redo MVD group, 73.7% in the later redo MVD group, and 15.3% in the observation group (P < 0.01). In the early redo MVD group, postoperative courses showed no significant differences between the first and the second operations. In the later redo MVD group, 1 patient developed a mild facial palsy and 1 had a cerebrospinal fluid leak. CONCLUSIONS: Our findings demonstrate that MVD is the most effective treatment for patients with HFS. An early reoperation is easier and safer than a later reoperation and may improve the likelihood of immediate relief. PMID- 29191536 TI - The Enigma of Orbital Compartment Syndrome After Lumbar Spine Surgery in the Prone Position: Case Report and Literature Review. AB - BACKGROUND: Perioperative visual loss after spinal surgery is a devastating complication for the patient and the surgical team. Two known major causes are ischemic optic neuropathy and central retinal artery occlusion (CRAO). Traditional understanding of CRAO has been consistently related to occurrence of periocular trauma and signs of increased intraorbital pressure in addition to visual loss. However, such orbital signs are not a feature of any common perioperative visual loss syndrome. CASE DESCRIPTION: A 55-year-old woman underwent prolonged lumbar decompression and fusion for spinal stenosis under general anesthesia in the prone position. At the end of surgery, periocular hyperemia, corneal edema, and a tense orbit on the right side were noted. Complete internal and external ophthalmoplegia was observed on examination. Orbital computed tomography confirmed the clinical diagnosis of orbital compartment syndrome. Bony decompression was performed, but the treated eye remained blind. Resolution of the complete ophthalmoplegia was observed during late follow-up. CONCLUSIONS: In retrospect, patients diagnosed with often misunderstood CRAO and ischemic optic neuropathy with orbital signs after spinal surgery most likely had orbital compartment syndrome. The inclusion of orbital signs in the clinical picture of ischemic optic neuropathy and CRAO is not only incorrect but also gives the impression of therapeutic futility, thereby preventing successful orbital decompression in a timely fashion. PMID- 29191537 TI - Risk Factors and Microbiology of Meningitis and/or Bacteremia After Transsphenoidal Surgery for Pituitary Adenoma. AB - OBJECTIVE: To investigate the incidence, bacteriologic features, and risk factors of posttranssphenoidal surgery (post-TSS) meningitis and/or bacteremia. METHODS: This retrospective study included 3242 patients who underwent TSS for pituitary adenoma at the Department of Neurosurgery of Peking Union Medical College Hospital between January 2012 and December 2016. Clinical data for patients with and without post-TSS meningitis and/or bacteremia were compared and analyzed. RESULTS: Meningitis and bacteremia developed after 27 (0.8%) and 26 (0.8%) procedures, respectively, and 6 patients (0.2%) developed both. Gram-positive organisms (coagulase-negative staphylococci, Streptococcus pneumonia, and S viridans) predominated in meningitis, whereas gram-negative organisms (Klebsiella pneumonia, Enterobacter aerogenes, and Escherichia coli) predominated in bacteremia. All identified species were sensitive to amikacin, imipenem, and meropenem. Antibiotic treatment cured 52 patients (7 died). In a multivariate analysis, the risk of meningitis and/or bacteremia was independently associated with diabetes (P < 0.001; odds ratio [OR], 6.06), previous surgery at the same location (P < 0.001; OR, 4.23), intraoperative cerebrospinal fluid leakage (P < 0.001l; OR, 4.63), and an endoscopic approach (P = 0.001; OR, 2.50). CONCLUSIONS: Meningitis and/or bacteremia remain critical postoperative complications of TSS for pituitary adenoma. The pathogens with drug sensitivity to antibiotics differed between meningitis and bacteremia. Early blood and cerebrospinal fluid bacterial cultures, drug susceptibility analyses, and appropriate antibiotic treatment can help control the rate of infection. PMID- 29191538 TI - Collet-Sicard Syndrome Attributable to Extramedullary Plasmacytoma of the Jugular Foramen. AB - BACKGROUND: Collet-Sicard syndrome is a rare manifestation of skull base disease involving the jugular and hypoglossal foramina. We report the first case of Collet-Sicard attributable to extramedullary plasmacytoma-multiple myeloma (EP MM) and the second case of EP-MM precipitating a jugular foramen syndrome (JFS) spectrum disorder. CASE DESCRIPTION: A 59-year-old woman presented with 4 months of left aural fullness and pulsatile tenderness, positional vertigo, hoarseness, and dysphagia. Examination identified left tongue weakness and nonspecific sensory abnormalities of the ear, pharynx, and throat localizing to cranial nerves IX-XII. Imaging revealed a 3.4 * 1.4 * 2.8 cm lytic lesion extending from the left jugular foramen into the posterior fossa, for which she was referred to neurosurgery and otolaryngology for consideration of resection. A second, much smaller (1.1-cm) lytic lesion in the left posterior occipital bone was incidentally discovered by the surgeon during preoperative consultation. A stereotactic biopsy of the occipital lesion was subsequently recommended, which identified plasma cell neoplasm. Serum studies and skeletal survey were consistent with MM, and a definitive pathologic diagnosis of MM with cranial EP was confirmed by bone marrow biopsy. CONCLUSION: Tumors of the jugular foramen present with a diverse array of lower cranial nerve deficits, including Collet Sicard syndrome, a rare subset of JFS-spectrum diseases. Paragangliomas are the most common jugular foramen neoplasms, followed by schwannomas and meningiomas; however, many other rare entities have been reported as masqueraders, and diligent work-up with consideration for preliminary biopsy is recommended, particularly in the presence of additional lesions, equivocal imaging findings, or cases arousing high suspicion. PMID- 29191539 TI - Prognostic Role of Microembolic Signals After Endovascular Treatment in Anterior Circulation Ischemic Stroke Patients. AB - BACKGROUND: Endovascular treatment (EVT) is an effective therapy for acute ischemic stroke due to large artery occlusion of the anterior circulation. Yet some patients do not experience clinical improvement despite successful recanalization and reperfusion. The reasons are unknown, but one possible explanation is microvessel obstruction downstream. The aim of this study was to assess the presence of microembolic signals (MES) with transcranial Doppler and define their role as predictors of clinical outcome in stroke patients after EVT. MATERIALS AND METHODS: We enrolled 40 consecutive patients (23 men, mean age 65.8 +/- 7.6 years) with an acute ischemic stroke caused by large artery occlusion of the anterior circulation who underwent EVT. Presence and rate of MES were assessed by 60-minute transcranial Doppler monitoring at the end of the procedure and after 15 days from stroke onset. RESULTS: MES were detected in 65% (26/40) of patients after EVT. Ipsilateral carotid occlusion (P = 0.05), >=50% ipsilateral carotid stenosis (P = 0.05), incomplete recanalization (P = 0.03), and inadequate collaterals (P = 0.04) were associated with a significantly higher MES count, which was correlated with a worse functional prognosis (P = 0.03), higher mortality (P = 0.02), higher distal embolization burden even outside the original ischemic territory (P = 0.02), and higher risk of cardiovascular events (P = 0.04). CONCLUSIONS: MES monitoring in stroke patients after EVT provides useful prognostic information, sheds light on the lack of clinical improvement despite successful recanalization, and might guide medical treatment in higher risk patients. PMID- 29191540 TI - Postoperative Neurologic Outcome in Patients with Pituitary Apoplexy After Transsphenoidal Surgery. AB - OBJECTIVE: Pituitary apoplexy can cause severe neuro-ophthalmologic or endocrinologic sequelae, requiring timely treatment. The present study was performed to evaluate postoperative neurologic outcomes and to identify their risk factors in patients who underwent transsphenoidal surgery for pituitary apoplexy. METHODS: Forty-one consecutive patients with pituitary apoplexy who underwent transsphenoidal surgery were reviewed retrospectively. The initial rates of visual acuity (VA) decrease, visual field (VF) defect, and ocular palsy were 34.1%, 46.3%, and 68.3%, respectively. The median maximal diameter and tumoral volume was 2.6 cm (range, 2.0-4.6 cm) and 5.3 cm3 (range, 2.4-38.8 cm3), respectively. Seventeen patients (41.5%) underwent surgery within 7 days. The median follow-up duration was 45 months (range, 12-196 months). RESULTS: At the last follow-up, 62.9% (22/35) of patients had made a full recovery from preoperative neurologic deficits, with partial recovery observed in the remaining patients. The rates of improvement and full recovery from VA decrease were 92.9% and 57.1%, respectively; those from VF defect were 94.7% and 36.8%, respectively; and those from ocular palsy were 100.0% and 96.4%, respectively. On multivariate analysis, initial visual impairment score (>=20) was the only significant risk factor for postoperative neurologic sequelae (P < 0.001; odds ratio, 40.8). Surgical timing was not associated with postoperative neurological recovery (P = 0.733). CONCLUSIONS: Ocular palsy was fully recovered in 96.4% patients with pituitary apoplexy after transsphenoidal surgery. Initial visual impairment status was found to be more strongly associated with postoperative neurologic recovery than surgical timing. PMID- 29191541 TI - Subtemporal "Interdural" Surgical Approach for "Giant" Facial Nerve Neurinomas. AB - OBJECTIVE: The management issues of 15 cases of giant and dumbbell-shaped facial neurinomas that extended both in the middle and posterior cranial fossa are reported. MATERIAL AND METHODS: During the period 2002 to June 2017, we surgically treated 15 cases of giant and dumbbell shaped facial neurinomas: 10 males and 5 females ranging from 17-59 years (average 34.2 years). Average duration of facial nerve weakness before seeking surgical relief was 49.46 months. Fourteen patients had varying degrees of hearing disturbance. Seven patients had ataxia. The sizes of the tumor ranged from 5.2-8 cm (average being 6.2 cm). The tumors were in an "interdural" location, both in the middle and in the posterior cranial fossa. An extradural subtemporal "interdural" approach was used to resect the tumor in both compartments. The dural cover of the tumor provided a well-defined surgical plane of dissection. Tumor recurrence was observed in 3 cases. The tumor was interdural even at the time of recurrence. CONCLUSIONS: Understanding the fact that the facial nerve neurinomas are interdural in nature and soft and necrotic in character can allow quick and safe surgery with a relatively small surgical exposure. PMID- 29191542 TI - Self-Inflicted Drywall Screws in the Sagittal Sinus. AB - A 30-year-old right-handed man with a history of schizophrenia presented with 2 self-inflicted drywall screws in the skull. The patient was sleepy but easily arousable; blood tests showed he had taken methamphetamines. Computed tomography and computed tomography angiography of the head showed the frontal screw abutted left of the superior sagittal sinus, and the posterior screw went through the superior sagittal sinus with no extravasation of contrast material at either site. Both screws were removed with exposure of the sagittal sinus using U-shaped craniectomies. There was no bleeding on the removal of the screws. It appears the posterior screw entered between the leaflets of the sagittal sinus dura mater. The patient had returned to work without any sequelae 1 month after injury. PMID- 29191543 TI - One-Level or Multilevel Interbody Fusion for Multilevel Lumbar Degenerative Diseases: A Prospective Randomized Control Study with a 4-Year Follow-Up. AB - BACKGROUND: The treatment of multilevel lumbar degenerative disease (LDD) is complicated and challenging, and the optimal surgical strategy remains controversial. OBJECTIVE: To compare the differences in clinical and radiologic outcomes and in complications after 1-level interbody fusion versus multilevel interbody fusion for the treatment of multilevel LDD. METHODS: A total of 100 patients with multilevel LDD were randomized in a 1:1 ratio into the 1-level interbody fusion group or the multilevel interbody fusion group. Clinical and radiologic results and major complications in the 2 groups were analyzed. Clinical outcomes were assessed using the Visual Analog Scale for radicular and back pain, the Oswestry Disability Index, and the short-form 36 physical score. Clinical status was assessed by the Whitecloud classification. Radiologic evaluation included assessment of lumbar lordosis, pelvic incidence, and sacral slope. RESULTS: There were no significant differences in clinical and radiologic results between the 2 groups. Procedure duration and intraoperative blood loss were significantly greater in the multilevel interbody fusion group than in the 1 level interbody fusion group; the multilevel interbody fusion group also had greater incidences of temporary nerve root palsy, wound infection, and adjacent segment disease. CONCLUSION: A hybrid technique including 1-level interbody fusion and multilevel posterolateral fusion is recommended for patients with multilevel LDD. PMID- 29191544 TI - Association of SOX17 Gene Polymorphisms and Intracranial Aneurysm: A Case-Control Study and Meta-Analysis. AB - BACKGROUND: Genome-wide association studies have revealed an association between SRY-box 17 (SOX17) gene and intracranial aneurysm (IA) formation. However, results were mainly derived from European and Japanese populations. We investigated the association between SOX17 gene polymorphisms and IA in a homogeneous Korean population. We performed a meta-analysis to assess these results in East-Asian populations. METHODS: This cross-sectional study included 187 age- and sex-matched patients with IA and 372 control subjects. Genetic association analysis was performed in the generalized linear model to identify associations between 4 single nucleotide polymorphisms and IA, including 95 patients with ruptured aneurysms and 92 with unruptured aneurysms. The East-Asian meta-analysis of 5100 IA cases and 7930 control cases was conducted under an inverse variance model. RESULTS: Among 4 single nucleotide polymorphisms that passed quality control tests, the minor C allele of rs1072737 was significantly associated with IA (odds ratio 0.69, 95% confidence interval 0.49-0.96, P = 0.03). None of the 4 single nucleotide polymorphisms showed a significant association between patients with ruptured and unruptured aneurysms. Meta analysis revealed that G alleles of rs10958409 and rs9298506 were significantly associated with IA in the East-Asian population after removing study heterogeneity (odds ratio 1.11, 95% confidence interval 1.04-1.19, P = 0.0023 and odds ratio 1.19, 95% confidence interval 1.07-1.32, P = 0.0016). CONCLUSIONS: Identification of genetic variants located near SOX17 is likely to be clinically significant for IA formation. rs10958409 and rs9298506 may increase risk of IA in East-Asian populations. Our findings may help in the identification of IA pathogenesis. PMID- 29191545 TI - Intracranial Erdheim-Chester Disease Mimicking Parafalcine Meningioma: Report of Two Cases and Review of the Literature. AB - BACKGROUND: Erdheim-Chester disease (ECD) is a rare, non-Langerhans cell histiocytosis that typically occurs in middle-aged patients. It is usually characterized by multifocal osteosclerotic lesions of the long-bones, however many cases have extraskeletal involvement. Central nervous system (CNS) involvement is common, but isolated CNS involvement at presentation has rarely been reported. CASE DESCRIPTION: Here we report two cases of dural-based ECD mimicking meningioma on imaging with no other identified sites of disease. CONCLUSION: ECD is a rare disease, with isolated CNS involvement reported only a few times in the literature. The significance of this presentation requires additional study and long-term follow up. PMID- 29191546 TI - Patched Closure of Dural Outlet of External Ventricular Drainage Catheter: Better Way to Prevent Cerebrospinal Fluid Leakage. AB - Postoperative continuous bloody cerebral spinal fluid drainage with external ventricular drainage catheter could decrease the incidence of inflammation. But the drainage catheter left in place will interrupt the watertight dura matter closure. To prevent the related cerebrospinal fluid leakage and subgaleal pseudomeningocele after the catheter removal, we developed a patched closure method to seal the dural outlet of the drainage catheter with a favorable clinical outcome. PMID- 29191547 TI - Pial Arteriovenous Fistula: A Brief Review and Report of 14 Surgically Treated Cases. AB - OBJECTIVE: The authors report their successful experience of treating 14 cases of pial arteriovenous fistula (PAVF) by direct surgery. METHODS: During the period January 2010 to April 2017, 14 patients with PAVF were treated by surgery. Only those patients were selected who had a single arterial feeding channel. There were 9 male patients and 5 female patients, and their ages ranged from 5 to 53 years (average, 19 years). Ten patients were younger than 20 years of age. Five patients presented clinical and radiologic features that suggested hemorrhage from the PAVF. Ten patients had seizures. Two patients had hemispheric symptoms or neurologic deficits at the time of presentation. In 12 patients, there were no gross neurologic deficits. The diagnosis was made on the basis of digital subtraction angiography in all patients and computed tomographic angiography in 8 patients. Angiography revealed that the PAVFs in 8 patients were supplied by the middle cerebral artery, in 5 patients by the anterior cerebral artery, and in 1 patient by branches of the basilar artery. Surgical procedures involved identification of the site of fistula, obliteration of the feeding artery, and resection of the entire venous varix. RESULTS: The PAVF was successfully excluded from circulation in all patients. There were no neurologic deficits related to the surgical procedure. CONCLUSIONS: Direct surgical resection of the entire PAVF is a safe, effective, and probably curative method of treatment. PMID- 29191548 TI - Evaluation of Enterprise Stent-Assisted Coiling and Telescoping Stent Technique as Treatment of Supraclinoid Blister Aneurysms of the Internal Carotid Artery. AB - BACKGROUND: Supraclinoid blister aneurysms (BAs) of the internal carotid artery are uncommon and deadly, and appropriate treatment is controversial. Endovascular reconstruction may allow treatment through aneurysm isolation. We report a single institution experience in the use of Enterprise stent-assisted coiling (ESAC) for treating BAs to appraise the safety and efficacy of this technique. METHODS: Patients treated with ESAC for a BA at our institution between 2013 and 2016 were retrospectively included in this study. Patients' aneurysm characteristics, progression status, aneurysm occlusion on follow-up angiography, and modified Rankin Scale (mRS) score were recorded and analyzed. Occlusion rates and neurologic outcomes were compared between patients treated with a single stent and those treated with multiple telescoping stents. RESULTS: Forty-four patients were included (17 males; average age, 47.3 years), and ESAC was successfully performed in all patients. Immediate postprocedure angiography revealed complete occlusion in 23 patients (52.3%), residual neck in 15 (34.1%), and residual aneurysm in 6 (13.6%). Twenty patients (45.5%) suffered perioperative cerebral vasospasm, and 3 (6.8%) died of secondary ischemic stroke. The duration of follow up ranged from 2.5 to 27 months (mean, 11.59 +/- 5.76 months). One patient with recurrence was treated with additional coiling, and another patient was treated with a covered stent. The use of telescoping stents was associated with a better complete aneurysm occlusion rate compared with the use of single stents (84.4% [27 of 34] vs. 44.4% [4 of 9]; P = 0.04). Follow-up mRS score was <=1 for 32 of 41 patients (78.4%). CONCLUSIONS: ESAC to treat BAs is safe, effective, and provides good clinical outcomes. ESAC with telescoping stents has a higher follow up complete occlusion rate compared with ESAC with single stents. PMID- 29191549 TI - Treatment of Brain Arteriovenous Malformations with Hemodynamic Aneurysms: A Series of 131 Consecutive Cases. AB - BACKGROUND: The natural history of hemodynamic aneurysms (HAs) associated with brain arteriovenous malformations (AVMs) remains controversial, with no single approach to treatment. The purpose of this study was to justify preventive treatment tactics for HAs that pose an increased risk of rupture based on hemodynamic studies demonstrating hypertension in the afferent bed after AVM exclusion. METHODS: This retrospective analysis included 131 of 1740 patients (8%) with brain AVMs and at least 1 aneurysm treated at Burdenko Neurosurgical Institute between 2000 and 2016. Treatment consisted of microsurgery, endovascular interventions, or a combination of modalities. Patients were evaluated with the modified Rankin Scale before and after treatment. RESULTS: A total of 205 aneurysms were discovered. Multiple HAs were found in 46 patients (35%), and were significantly more often associated with posterior fossa AVMs; in addition, most were distally located. There was no difference in the incidence of hemorrhage between proximal and distal HAs. Microsurgical treatment was marked by high radicalism; 85% of HAs and 94% of AVMs were totally excluded based on control studies. In 10 cases, aneurysms were found after AVM removal, including 4 de novo aneurysms. In 1 case, the aneurysm regressed after AVM treatment. The mortality rate was 2.3%. CONCLUSIONS: Preoperative imaging should be carefully examined for associated aneurysms before and after surgical treatment. Our data suggests that HA exclusion, either as the first step or simultaneously with AVM treatment, is most beneficial to patients. PMID- 29191550 TI - Lipopolysaccharide- and beta-1,3-glucan-binding protein from Litopenaeus vannamei: Purification, cloning and contribution in shrimp defense immunity via phenoloxidase activation. AB - Lipopolysaccharide- and beta-1,3-glucan-binding protein (LGBP) existed in diversity of invertebrates including shrimp plays a crucial role in an innate immunity via mediating the recognition of invading pathogens. In this study, LGBP was cloned and characterized from the hepatopancreas of Litopenaeus vannamei, named as LvLGBP. Its full-length cDNA of 1282 bp contained an open reading frame (1101 bp) encoding a peptide of 367 amino acids. The LGBP primary structure contained a glycosyl hydrolase domain, two integrin binding motifs, two kinase C phosphorylation sites, and two polysaccharide recognition motifs which were identified as a polysaccharide binding motif and a beta-1,3-glucan recognition motif. The LvLGBP transcripts were expressed mainly in the hepatopancreas. Upon challenge with Vibrio parahaemolyticus or white spot syndrome virus (WSSV), the LvLGBP mRNA expression was significantly up-regulated to reach a maximum at 48 h post injection. Its expression was also induced by lipopolysaccharide (LPS) or beta-1,3-glucan stimulation. RNAi-based silencing resulted in the critical suppression of LvLGBP expression. Knockdown of LvLGBP gene with co-inoculation by V. parahaemolyticus or WSSV led to increase in the cumulative mortality and reduce in the median lethal time. Native LGBP was detected only in the hepatopancreas as verified by Western blotting. Purified LGBP from the hepatopancreas exhibited the agglutinating and binding activity towards Gram negative bacterium V. parahaemolyticus with calcium-dependence. Its agglutinating activity was dominantly inhibited by LPS with higher potential than beta-1,3 glucan. Purified LvLGBP could significantly activate the hemocyte phenoloxidase activity in the presence of LPS (12.9 folds), while slight activation was detected with beta-1,3-glucan (2.0 folds). It could enhance the encapsulation by hemocytes but did not have antibacterial activity. These results provided evidence that LvLGBP might act as a pathogenic recognition protein to activate shrimp immune defense against invading pathogens via the agglutination, binding and enhancing encapsulation and phenoloxidase activity of the hemocytes. PMID- 29191551 TI - The Drosophila lymph gland is an ideal model for studying hematopoiesis. AB - Hematopoiesis in Drosophila melanogaster occurs throughout the entire life cycle, from the embryo to adulthood. The healthy lymph gland, as a hematopoietic organ during the larval stage, can give rise to two mature types of hemocytes, plasmatocytes and crystal cells, which persist into the pupal and adult stages. Homeostasis of the lymph gland is tightly controlled by a series of conserved factors and signaling pathways, which also play key roles in mammalian hematopoiesis. Thus, revealing the hematopoietic mechanisms in Drosophila will advance our understanding of hematopoietic stem cells and their niche as well as leukemia in mammals. In addition, the lymph gland employs a battery of strategies to produce lamellocytes, another type of mature hemocyte, to fight against parasitic wasp eggs, making the lymph gland an important immunological organ. In this review, the developmental process of the lymph gland and the regulatory networks of hematopoiesis are summarized. Moreover, we outline the current knowledge and novel insight into homeostasis of the lymph gland. PMID- 29191552 TI - Production of bioactive recombinant human Eb-peptide of pro-IGF-I and identification of binding components from the plasma membrane of human breast cancer cells (MDA-MB-231). AB - E-peptide of the pro-Insulin-like growth factor-I (pro-IGF-I) is produced from pre-pro-IGF-I by proteolytic cleavage in the post-translational processing. The human Eb-peptide (hEb-peptide), derived from the E domain of pro-IGF-IB isoform, is a bioactive molecule whose exact physiological role remains elusive. Accumulated evidence reported from our laboratory indicated that hEb-peptide possesses activity against multiple hallmark characteristics of solid tumor in different cancer cell types. In human breast carcinoma cells (MDA-MB-231), it was demonstrated that hEb-peptide can promote cell attachment to substratum, inhibit colony formation in a semisolid medium, reduce cancer cell invasion, and inhibit cancer-induced angiogenesis. Like the action of other peptide hormones, these cellular responses triggered by hEb may be initiated through binding to a receptor molecule residing on the surface of the cell. Our laboratory and the others have previously provided evidence demonstrating the existence of hEb peptide specific binding components residing on the cell membrane. In this study, we report the isolation and identification of eight protein molecules bound reversibly with hEb-peptide from the membrane preparation of MDA-MB-231 cells. Some of the identified proteins are known to be present at cell surface and function as receptors while the others are not. The functions of these molecules reveal strong correlation with the demonstrated activities of hEb-peptide on MDA MB-231cells, suggesting hEb-peptide activity on cancer cells might be mediated by these molecules. PMID- 29191553 TI - AMP and adenosine are both ligands for adenosine 2B receptor signaling. AB - Adenosine is considered the canonical ligand for the adenosine 2B receptor (A2BR). A2BR is upregulated following kidney ischemia augmenting post ischemic blood flow and limiting tubular injury. In this context the beneficial effect of A2BR signaling has been attributed to an increase in the pericellular concentration of adenosine. However, following renal ischemia both kidney adenosine monophosphate (AMP) and adenosine levels are substantially increased. Using computational modeling and calcium mobilization assays, we investigated whether AMP could also be a ligand for A2BR. The computational modeling suggested that AMP interacts with more favorable energy to A2BR compared with adenosine. Furthermore, AMPalphaS, a non-hydrolyzable form of AMP, increased calcium uptake by Chinese hamster ovary (CHO) cells expressing the human A2BR, indicating preferential signaling via the Gq pathway. Therefore, a putative AMP-A2BR interaction is supported by the computational modeling data and the biological results suggest this interaction involves preferential Gq activation. These data provide further insights into the role of purinergic signaling in the pathophysiology of renal IRI. PMID- 29191554 TI - Structure-based design, synthesis, and binding mode analysis of novel and potent chymase inhibitors. AB - Based on insight from the X-ray crystal structure of human chymase in complex with compound 1, a lactam carbonyl of the diazepane core was exchanged with O substituted oxyimino group, leading to amidoxime derivatives. This modification resulted in highly potent chymase inhibitors, such as O-phenylamidoxime 5f. X-ray crystal structure analysis indicated that compound 5f induced movement of the Leu99 and Tyr94 side chains at the S2 site, and the increase in inhibitory activity of O-phenyl amidoxime derivatives suggested that the O-phenyl moiety interacted with the Tyr94 residue. Surface plasmon resonance experiments showed that compound 5f had slower association and dissociation kinetics and the calculated residence time of compound 5f to human chymase was extended compared to that of amide compound 1. PMID- 29191555 TI - Discovery of benzotriazole-azo-phenol/aniline derivatives as antifungal agents. AB - A series of benzotriazole-azo-phenol/aniline derivatives were prepared and evaluated for their antifungal activities against six phytopathogenic fungi such as Fusarium graminearum, Fusarium solani, Alternaria alternate, Valsa mali, Botrytis cinerea, and Curvularia lunata. Among them, compounds IIf, IIn, and IIr showed a broad-spectrum of potent antifungal activities. Especially some compounds displayed 3.5-10.8 folds more potent activities than carbendazim against A. alternata and C. lunata. Notably, compounds IIc, IIm, and IIr exhibited good protective and therapeutic effects against B. cinerea at 200 MUg/mL. Their structure-activity relationships were also discussed. PMID- 29191557 TI - Synthesis of radioiodinated probes targeted toward matrix metalloproteinase-12. AB - Matrix metalloproteinase-12 (MMP-12, macrophage elastase) is a member of the MMP family that is responsible for the degradation of extracellular matrix, and is associated with the inflammatory process of chronic obstructive pulmonary disease (COPD). COPD, characterized by progressive and irreversible airflow obstruction, is recently a major cause of mortality and morbidity worldwide. Herein, to develop radioiodinated probes for the early diagnosis of COPD, we designed and synthesized novel MMP-12-targeted dibenzofuran compounds (1-3) with a variety of linker structures (carbamate, amide, and sulfonamide). In competitive enzyme activity assays, it was revealed that the linker structures significantly affected the inhibitory activity against and selectivity for MMP-12. Compound 1, with carbamate linker, demonstrated potent MMP-12 inhibitory activity (IC50 = 8.5 nM) compared to compound 2, with amide linker, and compound 3, with sulfonamide linker. Using bromo-substituted carbamate 13 as a radioiodination precursor, [125I]1 was successfully prepared to high radiochemical purity (over 98%) and good specific radioactivity (4.1 GBq/MUmol). These results suggest that radioiodinated compound 1 is potent as a novel MMP-12-targeted probe. PMID- 29191556 TI - Assessment of a pretomanid analogue library for African trypanosomiasis: Hit-to lead studies on 6-substituted 2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3]thiazine 8-oxides. AB - A 900 compound nitroimidazole-based library derived from our pretomanid backup program with TB Alliance was screened for utility against human African trypanosomiasis (HAT) by the Drugs for Neglected Diseases initiative. Potent hits included 2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3]thiazine 8-oxides, which surprisingly displayed good metabolic stability and excellent cell permeability. Following comprehensive mouse pharmacokinetic assessments on four hits and determination of the most active chiral form, a thiazine oxide counterpart of pretomanid (24) was identified as the best lead. With once daily oral dosing, this compound delivered complete cures in an acute infection mouse model of HAT and increased survival times in a stage 2 model, implying the need for more prolonged CNS exposure. In preliminary SAR findings, antitrypanosomal activity was reduced by removal of the benzylic methylene but enhanced through a phenylpyridine-based side chain, providing important direction for future studies. PMID- 29191558 TI - Where Is the Breakthrough Innovation for Parasite Control? AB - The need to improve parasite control to overcome drug-resistant parasite populations, and to improve compliance by more convenient drug application methods, is evident. While a number of incremental stepwise improvements are visible, the big disruptive innovation, an iPhone-equivalent breakthrough, has been hard to find. Why? PMID- 29191559 TI - Identifying radon priority areas and dwellings with radon exceedances in Bulgaria using stored CD/DVDs. AB - The implementation of the 2013/59/EURATOM directive in the part related to radon exposure imposes challenges for radon measurement methodology and radon survey design. Among them is the need to have estimates (preferably direct) of the annual average radon concentrations, which can be directly compared to the recommended reference levels. On this basis, the surveys should make possible the identification of dwellings with indoor radon above the reference levels and "radon priority areas" where significant proportion of the dwellings falls in this category. The performance of the CD/DVD method for radon measurements as a tool to address these issues is presented. A recent large scale field study based on the CD/DVD method that was carried out in the suburb area of Sofia, Bulgaria is described. Part of the studied area was affected in the past by the uranium mining and milling industry. In total 462 disks (CDs and DVDs) taken from 335 private dwellings from 10 districts in the region were analyzed. The results revealed the large heterogeneity in radon distribution in the area, with the percentage of dwellings with a 222Rn level above 300 Bq m-3 ranking from about 7% to 74%. The district of Yana, for which this percent was 74, was identified as the area of highest radon priority in the region. The paper also discusses how prompt identification of dwellings with radon above the reference level by CD/DVDs can be incorporated within an integrated approach to the radon problem. Within this approach the radon hazard is identified shortly after the stakeholder's decision to test, which allows fast solution of the problem without waiting the long (and usually demotivating) one-year period needed for direct results by the commonly used prospective methods. PMID- 29191560 TI - MSBIS: A Multi-Step Biomedical Informatics Screening Approach for Identifying Medications that Mitigate the Risks of Metoclopramide-Induced Tardive Dyskinesia. AB - In 2009 the U.S. Food and Drug Administration (FDA) placed a black box warning on metoclopramide (MCP) due to the increased risks and prevalence of tardive dyskinesia (TD). In this study, we developed a multi-step biomedical informatics screening (MSBIS) approach leveraging publicly available bioactivity and drug safety data to identify concomitant drugs that mitigate the risks of MCP-induced TD. MSBIS includes (1) TargetSearch (http://dxulab.org/software) bioinformatics scoring for drug anticholinergic activity using CHEMBL bioactivity data; (2) unadjusted odds ratio (UOR) scoring for indications of TD-mitigating effects using the FDA Adverse Event Reporting System (FAERS); (3) adjusted odds ratio (AOR) re-scoring by removing the effect of cofounding factors (age, gender, reporting year); (4) logistic regression (LR) coefficient scoring for confirming the best TD-mitigating drug candidates. Drugs with increasing TD protective potential and statistical significance were obtained at each screening step. Fentanyl is identified as the most promising drug against MCP-induced TD (coefficient: -2.68; p-value<0.01). The discovery is supported by clinical reports that patients fully recovered from MCP-induced TD after fentanyl-induced general anesthesia. Loperamide is identified as a potent mitigating drug against a broader range of drug-induced movement disorders through pharmacokinetic modifications. Using drug-induced TD as an example, we demonstrated that MSBIS is an efficient in silico tool for unknown drug-drug interaction detection, drug repurposing, and combination therapy design. PMID- 29191561 TI - Epitope-Specific Immunotherapy Targeting CD4-Positive T Cells in Celiac Disease: Safety, Pharmacokinetics, and Effects on Intestinal Histology and Plasma Cytokines with Escalating Dose Regimens of Nexvax2 in a Randomized, Double-Blind, Placebo-Controlled Phase 1 Study. AB - BACKGROUND: Nexvax2(r) is a novel, peptide-based, epitope-specific immunotherapy intended to be administered by regular injections at dose levels that increase the threshold for clinical reactivity to natural exposure to gluten and ultimately restore tolerance to gluten in patients with celiac disease. Celiac disease patients administered fixed intradermal doses of Nexvax2 become unresponsive to the HLA-DQ2.5-restricted gluten epitopes in Nexvax2, but gastrointestinal symptoms and cytokine release mimicking gluten exposure, that accompany the first dose, limit the maximum tolerated dose to 150MUg. Our aim was to test whether stepwise dose escalation attenuated the first dose effect of Nexvax2 in celiac disease patients. METHODS: We conducted a randomized, double blind, placebo-controlled trial at four community sites in Australia (3) and New Zealand (1) in HLA-DQ2.5 genotype positive adults with celiac disease who were on a gluten-free diet. Participants were assigned to cohort 1 if they were HLA-DQ2.5 homozygotes; other participants were assigned to cohort 2, or to cohort 3 subsequent to completion of cohort 2. Manual central randomization without blocking was used to assign treatment for each cohort. Initially, Nexvax2-treated participants in cohorts 1 and 2 received an intradermal dose of 30MUg (consisting of 10MUg of each constituent peptide), followed by 60MUg, 90MUg, 150MUg, and then eight doses of 300MUg over six weeks, but this was amended to include doses of 3MUg and 9MUg and extended over a total of seven weeks. Nexvax2-treated participants in cohort 3 received doses of 3MUg, 9MUg, 30MUg, 60MUg, 90MUg, 150MUg, 300MUg, 450MUg, 600MUg, 750MUg, and then eight of 900MUg over nine weeks. The dose interval was 3 or 4days. Participants, care providers, data managers, sponsor personnel, and study site personnel were blinded to treatment assignment. The primary outcome was the number of adverse events and percentage of participants with adverse events during the treatment period. This completed trial is registered with ClinicalTrials.gov, number NCT02528799. FINDINGS: From the 73 participants who we screened from 19 August 2015 to 31 October 2016, 24 did not meet eligibility criteria, and 36 were ultimately randomized and received study drug. For cohort 1, seven participants received Nexvax2 (two with the starting dose of 30MUg and then five at 3MUg) and three received placebo. For cohort 2, 10 participants received Nexvax2 (four with starting dose of 30MUg and then six at 3MUg) and four received placebo. For cohort 3, 10 participants received Nexvax2 and two received placebo. All 36 participants were included in safety and immune analyses, and 33 participants completed treatment and follow up; in cohort 3, 11 participants were assessed and included in pharmacokinetics and duodenal histology analyses. Whereas the maximum dose of Nexvax2 had previously been limited by adverse events and cytokine release, no such effect was observed when dosing escalated from 3MUg up to 300MUg in HLA-DQ2.5 homozygotes or to 900MUg in HLA-DQ2.5 non-homozygotes. Adverse events with Nexvax2 treatment were less common in cohorts 1 and 2 with the starting dose of 3MUg (72 for 11 participants) than with the starting dose of 30MUg (91 for six participants). Adverse events during the treatment period in placebo-treated participants (46 for nine participants) were similar to those in Nexvax2-treated participants when the starting dose was 3MUg in cohort 1 (16 for five participants), cohort 2 (56 for six participants), and cohort 3 (44 for 10 participants). Two participants in cohort 2 and one in cohort 3 who received Nexvax2 starting at 3MUg did not report any adverse event, while the other 33 participants experienced at least one adverse event. One participant, who was in cohort 1, withdrew from the study due to adverse events, which included abdominal pain graded moderate or severe and associated with nausea after receiving the starting dose of 30MUg and one 60MUg dose. The most common treatment-emergent adverse events in the Nexvax2 participants were headache (52%), diarrhoea (48%), nausea (37%), abdominal pain (26%), and abdominal discomfort (19%). Administration of Nexvax2 at dose levels from 150MUg to 900MUg preceded by dose escalation was not associated with elevations in plasma cytokines at 4h. Nexvax2 treatment was associated with trends towards improved duodenal histology. Plasma concentrations of Nexvax2 peptides were dose-dependent. INTERPRETATION: We show that antigenic peptides recognized by CD4-positive T cells in an autoimmune disease can be safely administered to patients at high maintenance dose levels without immune activation if preceded by gradual dose escalation. These findings facilitate efficacy studies that test high-dose epitope-specific immunotherapy in celiac disease.

AB - Dental caries is a chronic infectious disease that affects billions of people with large individual differences in activity. We investigated whether PRH1 and PRH2 polymorphisms in saliva acidic proline-rich protein (PRP) receptors for indigenous bacteria match and predict individual differences in the development of caries. PRH1 and PRH2 variation and adhesion of indigenous and cariogenic (Streptococcus mutans) model bacteria were measured in 452 12-year-old Swedish children along with traditional risk factors and related to caries at baseline and after 5-years. The children grouped into low-to-moderate and high susceptibility phenotypes for caries based on allelic PRH1, PRH2 variation. The low-to-moderate susceptibility children (P1 and P4a-) experienced caries from eating sugar or bad oral hygiene or infection by S. mutans. The high susceptibility P4a (Db, PIF, PRP12) children had more caries despite receiving extra prevention and irrespective of eating sugar or bad oral hygiene or S. mutans-infection. They instead developed 3.9-fold more caries than P1 children from plaque accumulation in general when treated with orthodontic multibrackets; and had basic PRP polymorphisms and low DMBT1-mediated S. mutans adhesion as additional susceptibility traits. The present findings thus suggest genetic autoimmune-like (P4a) and traditional life style (P1) caries, providing a rationale for individualized oral care. PMID- 29191564 TI - Dynamic ST-Segment Abnormality. AB - A 37-year-old man came to the emergency department because of several days of intermittent chest pain. An electrocardiogram (ECG) showed sinus rhythm, left atrial and left ventricular enlargement, and an early repolarization pattern. A second ECG recorded 10 minutes later was strikingly different, with ST-segment elevation and large upright T waves in the anterior precordial leads, interpreted as evidence of an ST-segment elevation myocardial infarction, and the cardiac catheterization team was activated. Closer inspection of the ECG, however, disclosed that the changes were because of intermittent ventricular pre excitation of the Wolff-Parkinson-White type, and no electrocardiographic, echocardiographic, or serum markers of myocardial infarction were found. PMID- 29191565 TI - Magnetic Resonance Imaging Correlates of Left Bundle Branch Disease in Patients With Nonischemic Cardiomyopathy. AB - The pathologic correlates of intraventricular conduction delays in patients with nonischemic cardiomyopathy (NIC) have been scarcely investigated. We assessed left ventricular (LV) structural, functional, and tissue abnormalities associated with intraventricular conduction left bundle disease (LBD), including left anterior hemiblock or complete left bundle branch block, in a cohort of patients with NIC submitted to cardiovascular magnetic resonance. Twelve-lead electrocardiogram and cardiovascular magnetic resonance were performed in 196 consecutive patients with NIC. The presence and extent of myocardial fibrosis was evaluated with late gadolinium enhancement (LGE) technique. Compared with normal intraventricular conduction patients, those with LBD were older (66 vs 59 years, p = 0.001), had greater LV volumes (p = 0.035 for end-diastolic and p = 0.009 for end-systolic volume) and mass (p = 0.034), and showed lower LV ejection fraction (33% vs 40%, p = 0.008). LGE was observed more commonly in LBD than in normal intraventricular conduction patients and was more often located in the ventricular septum (p < 0.001). On multivariate analysis, septal LGE was independently associated with a higher likelihood of LBD (odds ratio 6.1, 95% confidence interval 2.9 to 12.7, p < 0.001), even after correction for LV volumes, mass, and ejection fraction. In conclusion, in NIC, the presence of LBD is associated with worse LV remodeling and dysfunction than normal intraventricular conduction. Septal fibrosis yielded a 6-fold greater likelihood of LBD, independently of the degree of LV dilatation and systolic dysfunction. PMID- 29191563 TI - TGF-beta1/p53 signaling in renal fibrogenesis. AB - Fibrotic disorders of the renal, pulmonary, cardiac, and hepatic systems are associated with significant morbidity and mortality. Effective therapies to prevent or curtail the advancement to organ failure, however, remain a major clinical challenge. Chronic kidney disease, in particular, constitutes an increasing medical burden affecting >15% of the US population. Regardless of etiology (diabetes, hypertension, ischemia, acute injury, urologic obstruction), persistently elevated TGF-beta1 levels are causatively linked to the activation of profibrotic signaling networks and disease progression. TGF-beta1 is the principal driver of renal fibrogenesis, a dynamic pathophysiologic process that involves tubular cell injury/apoptosis, infiltration of inflammatory cells, interstitial fibroblast activation and excess extracellular matrix synthesis/deposition leading to impaired kidney function and, eventually, to chronic and end-stage disease. TGF-beta1 activates the ALK5 type I receptor (which phosphorylates SMAD2/3) as well as non-canonical (e.g., src kinase, EGFR, JAK/STAT, p53) pathways that collectively drive the fibrotic genomic program. Such multiplexed signal integration has pathophysiological consequences. Indeed, TGF-beta1 stimulates the activation and assembly of p53-SMAD3 complexes required for transcription of the renal fibrotic genes plasminogen activator inhibitor-1, connective tissue growth factor and TGF-beta1. Tubular-specific ablation of p53 in mice or pifithrin-alpha-mediated inactivation of p53 prevents epithelial G2/M arrest, reduces the secretion of fibrotic effectors and attenuates the transition from acute to chronic renal injury, further supporting the involvement of p53 in disease progression. This review focuses on the pathophysiology of TGF-beta1 initiated renal fibrogenesis and the role of p53 as a regulator of profibrotic gene expression. PMID- 29191566 TI - Usefulness of Achieving >=10 METs With a Negative Stress Electrocardiogram to Screen for High-Risk Obstructive Coronary Artery Disease in Patients Referred for Coronary Angiography After Exercise Stress Testing. AB - Functional capacity in exercise stress testing is an independent predictor of cardiac events. Routine use of nuclear perfusion imaging increases radiation burden and cost. Our goal was to assess the clinical utility of exercise functional capacity with stress electrocardiogram (ECG) as an adjunct in predicting the presence of high-risk obstructive coronary artery disease (CAD) on diagnostic coronary angiography. We performed a retrospective study of patients who underwent exercise stress testing for the evaluation of chest pain and underwent diagnostic coronary angiography within the subsequent 3 months. High risk CAD was defined as coronary artery diameter stenosis of >=70% in the proximal left anterior descending artery, >=70% diameter stenosis in 3 major epicardial arteries, or >=50% diameter stenosis in the left main artery. Univariable and multivariable analyses were performed to identify predictors of high-risk CAD. Of the 412 patients, 105 (25%) had high-risk CAD on coronary angiography. On multivariate logistic regression, we found that positive stress ECG, abnormal stress imaging, left ventricular ejection fraction, and male gender were independent predictors of high-risk CAD. The strongest predictor was positive stress ECG (hazard ratio 3.16, 95% confidence interval 1.90 to 5.27, p <0.001). Functional capacity measures alone were not independent predictors of high-risk CAD. Achieving >=10 METs with a negative stress ECG resulted in 94% sensitivity and 97% negative predictive value in identifying high-risk CAD. This supports the strategy for provisional use of myocardial perfusion imaging in patients with low functional capacity and/or abnormal stress ECG to minimize cost and radiation exposure. PMID- 29191568 TI - Value of the Electrocardiographic (P Wave, T Wave, QRS) Axis as a Predictor of Mortality in 14 Years in a Population With a High Prevalence of Chagas Disease from the Bambui Cohort Study of Aging. AB - We sought to investigate the prognostic value of the electrocardiogram (ECG) electrical axes (P wave, T wave and QRS) as predictors of mortality in the 14 year follow-up of the prospective cohort of all residents >=60 years living in the southeastern Brazilian city of Bambui, a population with high prevalence of Chagas disease (ChD). Baseline ECG axes were automatically measured with normal values defined as follows: P-wave axis 0 degrees to 75 degrees , QRS axis -30 degrees to 90 degrees , and T axis 15 degrees to 75 degrees . Participants underwent annual follow-up visits and death was verified using death certificates. Cox proportional hazards regression was used to assess the prognostic value of ECG axes for all-cause mortality, after adjustment for potential confounders. From 1,742 qualifying residents, 1,462 were enrolled, of whom 557 (38.1%) had ChD. Mortality rate was 51.9%. In multivariable adjusted models, abnormal P-wave axis was associated with a 48% (hazard ratio [HR] = 1.48 [95% confidence interval (CI) 1.16-1.88]) increased mortality risk in patients with ChD and 43% (HR = 1.43 [CI 1.13-1.81]) in patients without ChD. Abnormal QRS axis was associated with a 34% (HR = 1.34 [CI 1.04-1.73]) increased mortality risk in patients with ChD, but not in individuals without ChD. Similarly, in the ChD group, abnormal T-wave axis was associated with a 35% (HR = 1.35 [CI 1.07 1.71]) increased mortality, but not in patients without ChD. In conclusion, abnormal P-wave, QRS, and T-wave axes were associated with increased all-cause mortality in patients with ChD. Abnormal P-wave axis was associated with mortality also among those without ChD, being the strongest predictor among ECG variables. PMID- 29191569 TI - Safety and Efficacy of Beta Blockers in Cocaine-Using Patients With Heart Failure. PMID- 29191567 TI - Histamine H2 Receptor Polymorphisms, Myocardial Transcripts, and Heart Failure (from the Multi-Ethnic Study of Atherosclerosis and Beta-Blocker Effect on Remodeling and Gene Expression Trial). AB - Myocardial H2 receptor activation contributes to heart failure (HF) in preclinical models, and H2 receptor antagonists are associated with decreased HF incidence. This study evaluated whether H2 histamine receptor (HRH2) single nucleotide polymorphisms (SNPs) are associated with HF incidence and whether myocardial transcript abundance is associated with HF recovery. The association of SNPs in HRH2 with incident HF was characterized using Cox proportional hazards regression among participants in the Multi-Ethnic Study of Atherosclerosis. Differences in myocardial HRH2 transcripts were characterized in participants with dilated cardiomyopathy comparing 6 "super-responders" with 6 nonresponders to beta blockade in the Beta-Blocker Effect on Remodeling and Gene Expression Trial. In MESA, no candidate SNP was associated with HF in black, Hispanic, or white participants. The rs2241562 minor allele was present only in Chinese participants and the adjusted HF hazard among those with 1 or more copies of this allele was 3.7, 95% confidence interval 1.0 to 13.4. In BORG, super-responders to beta blockade had higher levels of myocardial HRH2 transcript at baseline compared with nonresponders (fragments per kilobase per transcript per million mapped reads: Variant 2, 5.5 +/- 1.1 compared with 3.2 +/- 0.8 in nonresponders, p = 0.002; Variant 1 + 2, 32.1 +/- 7.4 compared with 23.3 +/- 4.2 in nonresponders, p = 0.04). In conclusion, the presence of a minor allele at rs2241562 was associated with increased HF incidence in Chinese participants. Differences in myocardial HRH2 transcript abundance were seen in participants with dilated cardiomyopathy who responded to beta blockade. These observations support the hypothesis that HRH2 is involved in the pathogenesis of HF. PMID- 29191570 TI - The effect of interactions between genetics and cannabis use on neurocognition. A review. AB - BACKGROUND: Cannabis is one of the most widely-used drugs in industrialized countries. It is now well established that cannabis use impacts neurocognition. In the intoxication period time episodic memory, working memory and attention are impacted and impulsivity is increased. The long-term effects of cannabis use tend to be similar. Various internal factors, such as sex differences, modulate this impact. It is unclear whether genetic variations can also influence the impact of cannabis on neurocognition. We set out to examine the impact of genetic variations on neurocognition in cannabis users. METHOD: We conducted a search via the PubMed, Web of Science, and ScienceDirect databases to identify studies measuring neurocognition and assessing genotypes in the context of cannabis use. RESULTS: We included 13 articles. We found that working memory, verbal and visual memory and sustained attention are more impacted during intoxication in subjects with the Val COMT allele. COMT gene could also modulate sustained attention in regular use. The CNR1, AKT1, DBH and 5-HTT/SLC6A4 genes may also modulate effects. CONCLUSION: Most of these genes are linked to schizophrenia. A fuller understanding of their impact on the effects of cannabis on neurocognition would thus help elucidate the mechanisms linking cannabis and psychosis. However, evidence is still scant, and more research is needed. PMID- 29191571 TI - Distinguish self- and hetero-perceived stress through behavioral imaging and physiological features. AB - Stress reactivity is a complex phenomenon associated to multiple and multimodal expressions. Response to stressors has an obvious survival function and may be seen as an internal regulation to adapt to threat or danger. The intensity of this internal response can be assessed as the self-perception of the stress response. In species with social organization, this response also serves a communicative function, so-called hetero-perception. Our study presents multimodal stress detection assessment - a new methodology combining behavioral imaging and physiological monitoring for analyzing stress from these two perspectives. The system is based on automatic extraction of 39 behavioral (2D+3D video recording) and 62 physiological (Nexus-10 recording) features during a socially evaluated mental arithmetic test. The analysis with machine learning techniques for automatic classification using Support Vector Machine (SVM) show that self-perception and hetero-perception of social stress are both close but different phenomena: self-perception was significantly correlated with hetero perception but significantly differed from it. Also, assessing stress with SVM through multimodality gave excellent classification results (F1 score values: 0.9+/-0.012 for hetero-perception and 0.87+/-0.021 for self-perception). In the best selected feature subsets, we found some common behavioral and physiological features that allow classification of both self- and hetero-perceived stress. However, we also found the contributing features for automatic classifications had opposite distributions: self-perception classification was mainly based on physiological features and hetero-perception was mainly based on behavioral features. PMID- 29191572 TI - Th17 cells in primary Sjogren's syndrome: Pathogenicity and plasticity. AB - Th17 cells play an important physiological role at mucosal barriers, and are involved in inflammatory responses to pathogens. Th17 cells and their signature cytokine IL-17 are also present in salivary gland lesions of primary Sjogren's syndrome (pSS) patients and can be elevated in their peripheral blood. In pSS patients, clear correlations between increased Th17 cell activity and symptoms of the disease have not been found, but Th17 cells may contribute to disease progression, for example by supporting autoreactive B cell responses. In mouse models of pSS, Th17 cells play an important role in pathogenesis, particularly at disease onset, when there is a disturbed balance between T effector and T regulatory cells. Studying the pathogenicity of Th17 cells in humans is complicated due to the plasticity of this cell subset, allowing them to obtain different effector functions depending on the local environment. Th17 cells can develop towards Th17.1 cells, producing both IL-17 and IFN-gamma, or even towards Th1-like cells producing IFN-gamma in the absence of IL-17. These effector subsets may be more pathogenic than bona fide Th17 cells. Co-expression of IFN gamma by Th17 cells has been shown to promote chronic inflammation in several autoimmune diseases and may also contribute to pSS pathogenesis. In line with the noticeable role of IL-17 in pSS mouse models, interference with Th17 cell generation, recruitment or effector functions (e.g. IL-17 inhibition) can prevent or ameliorate disease in these models. Therapies targeting Th17 cells or IL-17 have not been tested so far in pSS patients, although treatment with rituximab seems to lower local and systemic IL-17 protein levels, and to a lesser extent also chemokine receptor-defined Th17 cells. In this review we discuss current knowledge of pathogenicity and plasticity of Th17 cells in human pSS and murine models of pSS. We postulate that plasticity towards Th17.1 cells in pSS may enhance pathogenicity of Th17 cells at the main target sites of the disease, i.e. salivary and lacrimal glands. PMID- 29191573 TI - Excessive interferon-alpha signaling in autoimmunity alters glycosphingolipid processing in B cells. AB - Excessive interferon-alpha (IFN-alpha) production by innate immune cells is a hallmark of autoimmune diseases. What other cell type secretes IFN-alpha and how IFN-alpha affects immune cell metabolism and homeostasis in autoimmunity are largely unclear. Here, we report that autoimmune B cells, arising from two different B cell-specific genetic lesions in mice, secrete IFN-alpha. In addition, IFN-alpha, found in abundance in autoimmunity, elicited profound changes in the B cell lipidome, increasing their expression of glycosphingolipids (GSLs) and leading to their CD1d-mediated depletion of iNKT cells in vitro and in vivo. IFN-alpha receptor blockade could reverse the loss of iNKT cells. Excessive stimulation of B cells with IFN-alpha altered the expression of enzymes that catalyze critical steps in GSL processing, increasing the expressions of glucosylceramide synthase (GCS) and globotrihexosylceramide synthase (Gb3S) but decreasing that of alpha-galactosidase A (alpha-galA). Inhibiting GCS or restoring alpha-galA expression prevented iNKT depletion by IFN-alpha-activated B cells. Taken together, our work indicated that excessive IFN-alpha perturbs GSL metabolism in B cells which in turn adversely affects iNKT homeostasis. PMID- 29191574 TI - [Collapsing focal segmental glomerulosclerosis induced by cytomegalovirus: A case report]. AB - Focal segmental glomerulosclerosis (FSGS) is a common cause of nephrotic syndrome in child and adult. The collapsing forms are of poor renal prognosis and are usually secondary to viral infections with, first and foremost, the human immunodeficiency virus. Among other viral etiologies, cytomegalovirus (CMV) is an uncommon cause. We report a case of a 32years-old patient with collapsing focal segmental glomerulosclerosis induced by cytomegalovirus with initial acute renal failure and proteinuria at 12.4g/24h. The treatment associated ganciclovir during 7days followed by valganciclovir during 14days and steroids at 1mg/kg/day. Renal function improved and proteinuria decreased with this treatment. Proteinuria increase again 3weeks after valganciclovir discontinuation while CMV Polymerase chain reaction (PCR) was positive. Therefore, valganciclovir has been resumed allowing renal function normalization and decrease in proteinuria to 4g/24h after negative CMVPCR assay after 15weeks. Anti-CMV therapy combined with steroids seems to provide a renal response in case of FSGS induced by CMV even if long term prognosis stays uncertain.

Both acquired and innate immune systems are involved in the development of this systemic disease. Lupus nephritis usually is the most serious manifestation of systemic lupus erythematosus, with significant morbidity and mortality. The physiopathological development of the renal involvement of lupus has been increasingly elucidated over the years and various target therapies have recently been developed. After some physiopathological reminders, we discuss the conventional treatment of lupus nephritis as well as the various therapeutic advances, in particular the contribution and the place of the new target therapies in the treatment of the lupus nephritis. PMID- 29191576 TI - [Comparison of citrate 4% and heparin as tunneled-catheters-locking solution in chronic hemodialysis]. AB - INTRODUCTION: Citrate 4% is an alternative to heparin as catheter-locking solution in chronic hemodialysis patients. We compared catheter dysfunction episodes, dialysis adequacy, plasminogen-tissular activators use and costs according to catheter-locking solution in our centre. METHODS: Prospective, monocentric, cohort study (NephroCare Tassin-Charcot) on 49 prevalent patients in chronic hemodialysis. Two main groups were formed according to the prescription of catheter-locking solution at the beginning of the study (03/02/2016) and followed until 05/10/2016: heparin (n=26) and citrate (n=22). RESULTS: The number of diabetic patients was higher in the citrate group (12/22) than in the heparin one (5/26; P=0.025). The 2 groups were comparable for the other studied variables. We didn't observe any difference in terms of catheter-dysfunction (4.23 versus 4.14% in heparin and citrate groups, respectively; P=1.0) and dialysis adequacy. The prescription of citrate was associated with lower TPA uses (1/604 versus 14/946; P=0.022) and lower costs (1.42 ? for one session versus 2.94 ?). CONCLUSION: Administration of citrate 4% as a catheter-locking solution is not inferior to heparin in terms of catheter-dysfunction episodes, is associated with similar dialysis adequacy results, lower plasminogen-tissular activators uses and reduced costs in chronic prevalent hemodialysed patients. PMID- 29191577 TI - Electrical stimulation of the insular cortex as a novel target for the relief of refractory pain: An experimental approach in rodents. AB - Cortical electrical stimulation (CES) has shown to be an effective therapeutic alternative for neuropathic pain refractory to pharmacological treatment. The primary motor cortex(M1) was the main cortical target used in the vast majority of both invasive and non-invasive studies. Despite positive results M1-based approaches still fail to relieve pain in a significant proportion of individuals. It has been advocated that the direct stimulation of cortical areas directly implicated in the central integration of pain could increase the efficacy of analgesic brain stimulation. Here, we evaluated the behavioral effects of electrical stimulation of the insular cortex (ESI) on pain sensitivity in an experimental rat model of peripheral neuropathy, and have described the pathways involved. Animals underwent chronic constriction of the sciatic nerve in the right hind limb and had concentric electrodes implanted in the posterior dysranular insular cortex. Mechanical nociception responses were evaluated before and at the end of a 15-min session of ESI (60Hz, 210MUs, 1V). ESI reversed mechanical hypersensitivity in the paw contralateral to the brain hemisphere stimulated, without inducing motor impairment in the open-field test. Pharmacological blockade of MU-opioid (MOR) or type 1-cannabinoid receptors (CB1R) abolished ESI-induced antinociceptive effects. Evaluation of CB1R and MOR spatial expression demonstrated differential modulation of CB1R and MOR in the periaqueductal gray matter (PAG) of ESI-treated rats in sub-areas involved in pain processing/modulation. These results indicate that ESI induces antinociception by functionally modulating opioid and cannabinoid systems in the PAG pain circuitry in rats with experimentally induced neuropathic pain. PMID- 29191578 TI - Gastrin-releasing peptide attenuates fear memory reconsolidation. AB - BACKGROUND: Gastrin Releasing Peptide (GRP) may play a role in fear learning. The GRP Receptor is expressed in the basolateral amygdala and hippocampus, and central administration of GRP mediates fear learning. The effects of GRP on reconsolidation, however, have been minimally explored. Reconsolidation, the process by which formed memories are rendered labile following recall, provides a window of opportunity for pharmacological intervention. Although evidence suggests the window of opportunity to alter reactivated consolidation memory can be as long as 6 h, shorter intervals have not been extensively investigated. METHOD: Male Sprague-Dawley rats received six 1.0 mA continuous footshocks. 24 h later, were re-exposed to the context (shock chamber). Immediately following memory retrieval rats received i.p. injection of GRP (10 nmol/kg), Flumazenil (1 mg/kg), GRP + Flumazenil (10 nmol/kg GRP with 1 mg/kg Flumazenil), or Vehicle. Other groups received GRP or Vehicle at 0, 10, 30, or 60 min post-reactivation. 24 h and 5 days later rats were assessed for fear expression upon re-exposure to the fearful stimulus. RESULTS: GRP significantly attenuated the reconsolidation of learned fear when administered immediately (but not 10 min or longer) following recall. Some of the variability in the impact of treatments aimed at disrupting fear memories may be governed, in part, by the time-frame of the reconsolidation window. Our results indicate that the effect of immediate administration persisted for at least 5 days. Co-administration of benzodiazepine receptor antagonist Flumazenil blocked this effect, suggesting the effect is mediated via a GABAergic mechanism. PMID- 29191579 TI - Prenatal stress increases adult vulnerability to cocaine reward without affecting pubertal anxiety or novelty response. AB - Prenatal stress (PS) induces long-lasting molecular alterations in brain circuits of the offspring and increases the propensity to develop neuropsychiatric diseases during adulthood, including mood disorders and drug addiction. A major goal of this study was to assess the impact of PS on pubertal behaviour and adult vulnerability to cocaine-induced conditioning place preference (CPP). We therefore evaluated pubertal novelty response and anxiety-like behaviour in control (C) and PS rats, and then, we examined cocaine-induced CPP in those animals during adulthood. We found no differences between C and PS groups on pubertal behaviour, however, only PS rats showed a significant cocaine-induced CPP. To further analyze our results, we classified cocaine-treated rats regarding their CPP score in Low CPP or High CPP and we then analysed their pubertal behaviour. We found different relations of anxiety-like behaviour to cocaine reward as a function of PS exposure: for C group, High CPP and Low CPP had shown similar levels of anxiety-like behaviour at puberty; on the contrary, for PS group, High CPP had shown lower anxiety-like behaviour than Low CPP rats. This study underscores the importance of considering prenatal exposure to stress when analysing the relationship between anxiety and cocaine vulnerability. Moreover, the evaluation of behavioural traits at puberty opens the possibility of early intervention and will allow the development of specific prevention strategies to avoid the devastating consequences of drug addiction later in life. PMID- 29191580 TI - Anaplastic lymphoma kinase gene rearrangement predicts better prognosis in NSCLC patients: A meta-analysis. AB - OBJECTIVE: For non-small cell lung cancer (NSCLC), anaplastic lymphoma kinase (ALK) rearrangement and epidermal growth factor receptor (EGFR) mutations are predictive markers of the treatment benefit from selective tyrosine kinase inhibitors (TKI). However, their prognostic roles remained uncertain. Thus, we conducted this meta-analysis to evaluate the prognosis of ALK+ NSCLC patients in the treatment of surgery, chemotherapy, and/or EGFR-TKI. MATERIALS AND METHODS: PubMed, Embase and Cochrane databases were thoroughly searched to identify relevant studies. Primary endpoints of this study included overall survival (OS), recurrence/progression free survival (RFS/PFS) and objective response rate (ORR). All statistical analyses were performed via REVIEW MANAGER (version 5.3). RESULTS: In total, 15 studies involving 4981 NSCLC patients were included. This study demonstrated that smoking status profoundly influenced prognosis of ALK related NSCLC. In the general population with NSCLC, compared with ALK- arm, ALK+ arm obtained a significantly better prognosis (HR=0.81 for OS, 95% CI=0.72-0.91; 0.80 for RFS/PFS, 95% CI=0.70-0.90), even after further stratification analysis according to disease stage. However, in the non-smoking population with NSCLC, compared with ALK- arm, those in the ALK+ arm had a worse prognosis (HR=1.65 for OS, 95% CI=1.28-2.12; 1.23 for RFS/PFS, 95% CI=1.05-1.44). Furthermore, ALK+ patients experienced a significantly higher ORR in pemetrexed-based chemotherapy but not in EGFR-TKI. CONCLUSIONS: Smoking status had a profound influence on the ALK-related prognosis of NSCLC. ALK rearrangement predicted a better prognosis in the general population with NSCLC, but a poor survival in the non-smoking population. Therefore, stratification according to smoking status is strongly recommended for future studies exploring ALK-related prognosis. PMID- 29191581 TI - Prognostic value of HLA-A2 status in advanced non-small cell lung cancer patients. AB - INTRODUCTION: The class I human leucocyte antigen (HLA) molecules play a critical role as an escape mechanism of antitumoral immunity. HLA-A2 status has been evaluated as a prognostic factor in lung cancer, mostly in localized disease and with inconsistent findings. We evaluated the role of HLA-A2 status as a prognostic factor in a large and homogeneus cohort of advanced NSCLC patients. METHODS: Advanced NSCLC patients eligible for platinum-based chemotherapy were consecutively included in a single center between October 2009 and July 2015 in the prospective MSN study (NCT02105168). HLA-A2 status was analysed by flow cytometry. Clinical, pathological and molecular data were collected. A Cox model was used for prognostic analyses. RESULTS: Of 545 stage IIIB/IV NSCLC patients included, 344 (63%) were male, 466 (85%) were smokers, 447 (83%) had PS 0-1, 508 (93%) had stage IV, 407 (75%) had an adenocarcinoma and median age was 61 years (range, 21-84). Incidence of patients with EGFRmut, ALK-positive and KRASmut was 14% (49/361), 9% (29/333) and 31% (107/350), respectively. The overall rate of HLA-A2 positivity was 48%. No association was observed between HLA-A2 status and any patient or tumor characteristics analyzed. With a median follow-up of 27.1 months, median OS was 12.8 months [95%CI 11.0-14.6] in HLA-A2+ vs. 12.5 months [95%CI 10.4-15.3] in HLA-A2- patients (HR 1.05 [95%CI 0.86-1.29], p=0.61). Median progression-free survival was similar in the two cohorts. CONCLUSION: HLA-A2 status was not identified as prognostic for benefit in a large advanced NSCLC population treated with platinum-based chemotherapy. PMID- 29191583 TI - Wolf in Sheep's Clothing: Primary Lung Cancer Mimicking Benign Entities. AB - Lung cancer is the most common cancer worldwide. On imaging, it typically presents as mass or nodule. Recognition of these typical cases is often straightforward, whereas diagnosis of uncommon manifestations of primary lung cancer is far more challenging. Lung cancer can mimic a variety of benign entities, including pneumonia, lung abscess, postinfectious scarring, atelectasis, a mediastinal mass, emphysema and granulomatous diseases. Correlation with previous history, clinical and biochemical parameters is necessary in the assessment of these cases, but often aspecific and inconclusive. Whereas 18F-fluorodeoxyglucose (18F-FDG) Positron Emission Tomography is the cornerstone in staging of lung cancer, its role in diagnosis of these uncommon manifestations is less straightforward since benign entities can present with increased 18F-FDG-uptake and, on the other hand, a number of these uncommon lung cancer manifestations do not exhibit increased uptake. Chest Computed Tomography (CT) is the imaging modality of choice for both lesion detection and characterization. In this pictorial review we present the wide imaging spectrum of CT-findings as well as radiologic-pathologic correlation of these uncommon lung cancer manifestations. Knowledge of the many faces of lung cancer is crucial for early diagnosis and subsequent treatment. A multidisciplinary approach in these cases is mandatory. PMID- 29191582 TI - Patterns of care and survival among patients with malignant mesothelioma in the United States. AB - BACKGROUND: Mesothelioma is a rare malignancy that is associated with poor survival. This study aimed to describe the patterns of care and subsequent survival among malignant mesothelioma patients in the United States, while adjusting for patient demographics and comorbidities. METHODS: A random sample of patients diagnosed with histologically confirmed mesothelioma in 2011, as reported to the National Cancer Institute's Surveillance Epidemiology and End Results program, were included. Logistic regression and Cox proportional hazard regression were utilized to identify factors associated with receipt of therapy and all-cause mortality, respectively, among patients with pleural mesothelioma. RESULTS: This study included 389 patients with pleural mesothelioma and 53 patients with non-pleural mesothelioma. Almost a third (29.3%) of the pleural patients and 21.5% of the non-pleural patients received no therapy. Additionally, approximately 60% of both patient groups received systemic therapy. Among pleural mesothelioma patients, receipt of therapy was less likely among older patients. Median survival was 9 months among the pleural patients and 18 months among the non-pleural patients. Receipt of either surgery or systemic therapy and particularly the combination of these two modalities was associated with better all-cause survival. Additionally, among pleural mesothelioma patients, younger age and lower socioeconomic status were found to be associated with better all cause survival. Comorbidity score was not found to be associated with receipt of treatment nor was it independently associated with survival among pleural mesothelioma patients. CONCLUSION: These findings indicate the need for efforts to ensure equitable application of currently available therapies to all patients. PMID- 29191585 TI - Treatment outcomes by histology in REVEL: A randomized phase III trial of Ramucirumab plus docetaxel for advanced non-small cell lung cancer. AB - OBJECTIVES: Ramucirumab, a recombinant human immunoglobulin G1 monoclonal antibody inhibiting vascular endothelial growth factor receptor-2, increased overall survival (OS) combined with docetaxel versus docetaxel alone in non-small cell lung cancer (NSCLC) in the REVEL trial. Pre-specified exploratory analysis examined efficacy and safety by histology. MATERIALS AND METHODS: 1253 patients with NSCLC were randomized to receive ramucirumab (10mg/kg; n=628) plus docetaxel (75mg/m2) or placebo plus docetaxel (n=625) after disease progression on or after platinum-based therapy, with or without bevacizumab or maintenance therapy. OS was analyzed using Kaplan-Meier method. Hazard ratios (HRs) and 95% confidence intervals (CIs) were obtained using an unstratified Cox proportional hazards model. Primary quality-of-life analysis was time to deterioration (TtD) of the Lung Cancer Symptom Scale (LCSS) scores using the Kaplan-Meier method and Cox regression. RESULTS: Median OS for adenocarcinoma was 11.2 months for ramucirumab docetaxel (n = 377) and 9.8 months for placebo-docetaxel (n=348); HR=0.83 (95% CI: 0.69-0.99). In squamous disease, median OS was 9.5 months for ramucirumab docetaxel (n=157) versus 8.2 months for placebo-docetaxel (n=171); HR 0.88 (95% CI: 0.69-1.13). Median OS for other nonsquamous was 10.8 months for ramucirumab docetaxel (n=74) and 9.3 months for placebo-docetaxel (n=78); HR=0.86 (95% CI: 0.59-1.26). Treatment-emergent adverse events were comparable between treatment arms across histologic subgroups. TtD for LCSS scores was similar between treatment arms in the nonsquamous and squamous subgroups. CONCLUSION: REVEL demonstrated similar favorable efficacy and manageable safety for ramucirumab docetaxel across histologic subgroups of NSCLC. PMID- 29191584 TI - Circulating tumor cells as a predictive biomarker in patients with small cell lung cancer undergoing chemotherapy. AB - BACKGROUND: There are no biomarkers for assessment of disease burden or activity of therapy in SCLC. PATIENTS AND METHODS: We conducted a prospective study enumerating serial CTCs in patients with newly diagnosed limited disease (LD) and extensive stage (ED) SCLC. CTCs demonstrating DNA damage and apoptosis based on gammaH2AX and M30 staining were also assessed. We correlated CTC number with disease stage, survival outcomes and tumor burden by RECIST. RESULTS: Between 03/2011-10/2013, 50 evaluable patients were enrolled (20 LD). Baseline CTC number was higher for ED (median CTC 71 vs. 1.5 for LD; p 0.0004). Patients with <5 CTC had longer PFS but not OS (11 vs. 6.7 months, p 0.0259 and 15.5 vs. 12.9 months, p 0.4357). A higher cutoff (CTC<50 or CTC>=50) was significantly correlated with both OS (20.2 vs. 11.8 months, p 0.0116) and PFS (10 vs. 4.8 months, p 0.0002). Patients with <5 CTC on day 1 of cycle 2 had longer PFS (10 vs. 3.17 months, p<0.001) and OS (18 vs. 9 months, p 0.0001). Patients with an increase in gamma2HAX-positive CTCs after chemotherapy had longer OS compared to patients without an increase (25.3 vs. 9 months, p 0.15). CONCLUSIONS: This study demonstrates that CTCs at baseline and Cycle 2 of chemotherapy correlate with disease stage and survival in patients with SCLC, suggesting that CTCs may be used as a surrogate biomarker for clinical response. Confirmatory prospective clinical trials are needed before we can incorporate routine evaluation of CTCs into clinical practice. PMID- 29191586 TI - Outcome of radical local treatment of non-small cell lung cancer patients with synchronous oligometastases. AB - OBJECTIVES: Patients with stage IV non-small cell lung cancer (NSCLC) are considered incurable and are mainly treated with palliative intent. This patient group has a poor overall survival (OS) and progression free survival (PFS). The purpose of this study was to investigate PFS and OS of NSCLC patients diagnosed with synchronous oligometastatic disease who underwent radical treatment of both intrathoracic disease and metastases. MATERIALS AND METHODS: Patients with NSCLC and oligometastatic disease at diagnosis, who were treated with radical intent between 2008 and 2016, were included in this observational study. Treatment consisted of systemic treatment and radical radiotherapy or resection of the intrathoracic disease. Treatment of the metastases consisted of radical or stereotactic radiotherapy, surgical resection or radiofrequency ablation. RESULTS AND CONCLUSIONS: Ninety-one patients (52% men, mean age 60 years) in good performance status were included. Thirty-eight patients (42%) died during follow up (median follow-up 35 months). The cause of dead was lung cancer in all patients, except one. Sixty-three (69%) patients developed recurrent disease. Eleven recurrences (17%) occurred within the irradiated area. For the whole group, the median PFS was 14 months (range 2-89, 95%CI 12-16) and the median OS was 32 months (range 3-89, 95%CI 25-39). The 1- and 2-year OS rates were 85% and 58% and the 1- and 2-year PFS rates were 55% and 27%, respectively. Radical local treatment of a selected group of NSCLC patients with good performance status presenting with synchronous oligometastatic disease resulted in favorable long term PFS and OS. PMID- 29191587 TI - Phenotypes of lung cancer and statistical interactions between tobacco smoking and occupational exposure to asbestos and crystalline silica from a large case only study: The CaProMat study. AB - OBJECTIVES: The aim of this study was to assess the effect modification of the association between tobacco smoking and phenotypes of lung cancer (histological type, tumor location, and age at diagnosis) by occupational exposure to asbestos or to crystalline silica. MATERIALS AND METHODS: The CaProMat study is a pooled case-only study including 7256 male lung cancer cases recruited between 1996 and 2011 in France and Canada. Two job-exposure matrices (JEMs) were used to assess occupational exposure to asbestos and crystalline silica. Statistical interactions between tobacco smoking and occupational exposure to asbestos or crystalline silica were assessed using unconditional logistic regression models for histological type and tumor location and linear regression models for age at diagnosis. RESULTS: Tobacco smoking was associated with squamous cell carcinoma and small cell carcinomas as well as an earlier age at diagnosis. Additional exposure to either asbestos or crystalline silica did not modify the effect of tobacco smoking for either histological type or age at diagnosis. Neither tobacco smoking nor occupational exposure to asbestos or crystalline silica influenced tumor location. CONCLUSIONS: Tobacco smoking was the main factor related to histological type and age at diagnosis. Those associations were not modified by occupational exposure to asbestos or crystalline silica. PMID- 29191588 TI - Timeliness of access to lung cancer diagnosis and treatment: A scoping literature review. AB - The Institute of Medicine recently called for increased understanding of and commitment to timely care. Lung cancer can be difficult to diagnose, resulting in delays that may adversely affect survival; rapid diagnosis and treatment therefore is critical for enabling improved patient outcomes. This scoping review provides an update on timeliness of lung cancer care over the past decade. We searched PubMed for English-language articles published from 2007 to 2016 that report wait time intervals related to diagnosis and treatment of lung cancer. Two authors independently reviewed titles and abstracts for inclusion. Abstracted data included sample size, patient population, study type, dates of study, wait times, and information on disparities, survival, costs, healthcare utilization, and interventions. The final review included 65 studies from 21 different countries. A total of 96 unique variations of wait intervals were reported (e.g., time to diagnosis from first pulmonologist visit, imaging, or initial evaluation), making comparisons across studies difficult. The most common interval was diagnosis to treatment initiation, with reported medians ranging from 6 to 45 days. Fourteen articles reported information on survival, 14 on healthcare utilization, 18 on disparities, and 14 on interventions; results varied by study. Significant variation exists in how access to care time delays are reported. Many patients across different facilities and countries appear to be facing substantial waits to receive lung cancer diagnosis and care. Further research, using common wait-interval metrics, is needed to evaluate and improve timeliness of lung cancer diagnosis and treatment. PMID- 29191589 TI - Does timeliness of care in Non-Small Cell Lung Cancer impact on survival? AB - OBJECTIVES: To measure time intervals in the management of Non-Small Cell Lung Cancer (NSCLC) patients, identify factors associated with this and evaluate the impact of timeliness of care on survival. MATERIALS AND METHODS: A retrospective cohort of South Western Sydney (SWS) patients with newly diagnosed NSCLC from 2006 to 2012 was identified from the SWSLHD Clinical Cancer Registry. Time intervals evaluated in days were "Diagnosis to Initial Treatment" and "Referral to Initial Treatment". Treatment included surgery, radiotherapy, systemic therapy and palliative care. Negative binomial regression and Cox regression were used to identify factors associated with timeliness of care and survival respectively. RESULTS: 1926 NSCLC patients were identified of whom 1729 had initial treatment recorded. Initial treatment was palliative care in 35% (n=611), radiotherapy in 29% (n=498), surgery in 18% (n=314) and systemic therapy in 18% (n=306). Median time from diagnosis to treatment was 32days (IQR 15-58). Median time from specialist referral to treatment was 35days for surgery (IQR 21-49), 21days for radiotherapy (IQR 13-32) and 25days (IQR 15-35) for systemic therapy. On multivariable analysis, age between 70 and 79 years, ECOG performance status 0-1, Stage I-III NSCLC and systemic treatment were associated with longer Diagnosis to Treatment: intervals. Diagnosis to Treatment: interval was not associated with mortality in Stage I & II NSCLC. A longer interval was associated with reduced mortality in Stage III (HR 0.99, 95%CI 0.99-1.0, p=0.03) and Stage IV NSCLC (HR=0.99, 95% CI 0.99-0.99, p=0.0008). CONCLUSIONS: At the population level, longer Diagnosis to Treatment: time intervals were not associated with adverse survival outcomes in NSCLC. However, delays to treatment may impact on other outcomes such as patient's psychological wellbeing and quality of life which were not measured in this study. PMID- 29191590 TI - Clinical predictors of survival in young patients with small cell lung cancer: Results from the California Cancer Registry. AB - BACKGROUND: Small cell lung cancer (SCLC) is an often lethal disease that commonly occurs in older individuals with a history of heavy tobacco use. Limited epidemiologic and outcomes data are available on young SCLC patients aged less than 50 years of age. We assessed clinical variables related to cause specific survival (CSS) of young patients with SCLC. METHODS: SCLC patients in the California Cancer Registry diagnosed between 1998 and 2012 were included. Primary outcome measure was CSS. Hazard ratios (HR) for CSS were calculated using Cox Proportional Hazards (pH) models for all ages & for patients <50 years, adjusted for baseline variables: age, gender, stage, race, year of diagnosis, initial treatment, socioeconomic status (SES), and location (urban vs. rural). RESULTS: We identified 22,863 SCLC patients, of which 975 were less than 50 years of age (4.2%). Most patients <50years of age were male (51%), white race (71%), and had stage IV disease (60%). A lower proportion of patients aged 50 years or younger was diagnosed in later years: from 40% in 1998-2002 to 24% in 2008-2012. For all SCLC patients, age less than 50 years was an independent predictor of improved CSS (HR=0.82, p<0.0001). Multivariate Cox pH models showed that in younger patients, female sex (HR=0.81, p=0.0045), Asian race (HR=0.57, p=0.0075), and rural residence (HR=0.75, p=0.042) were associated with better CSS, among other variables. CONCLUSIONS: In patients with SCLC, age less than 50 years was an independent predictor of improved CSS. Baseline clinical variables associated with better CSS were identified. These results have potential clinical applications. PMID- 29191591 TI - Fine-mapping the MHC region in Asian populations identified novel variants modifying susceptibility to lung cancer. AB - OBJECTIVES: The polymorphic major histocompatibility complex (MHC) plays a vital role in the immune system and drives predisposition to multiple cancers. A number of lung cancer-related genetic variants in the MHC have been identified in recent genome-wide association studies; however, the causal variants remain unclear. MATERIALS AND METHODS: In the present study, we conducted a large-scale fine mapping study of lung cancer in the MHC region of 13,945 unrelated Asian individuals to search for potential causal variants. We used the recently constructed Pan-Asian panel as the reference and imputed eight HLA genes (HLA-A, HLC-B, HLA-C, HLA-DRB1, HLA-DQA1, HLA-DQB1, HLA-DPA1, and HLA-DPB1) using SNP2HLA software. RESULTS: We identified one single nucleotide polymorphism, rs12333226 (OR=1.41, P=3.97*10-7), five HLA amino acid polymorphisms in HLA-DRB1 (OR=0.89, P=7.51*10-6-8.57*10-6), and one two-digit classic HLA allele HLA-A*11 (OR=0.87, P=9.68*10-6) that were strongly associated with the risk of lung cancer. Rs12333226 was an expression quantitative trait locus of HLA-A and HLA-H in circulating monocytes, and exerted effect on lung cancer risk especially in the younger. HLA-DRbeta1 positions 10, 16, and 25 drove the effect of one reported SNP rs2395185. The peptide position analysis identified additional lung cancer susceptibility amino acid positions, including HLA-DRbeta1 position 30 and 11 (Pomnibus=6.11*10-5 and 6.91*10-5), HLA-DQa1 47 and 76 (Pomnibus=3.96*10-4 and 1.41*10-2) and HLA-A 152 (Pomnibus=4.86*10-4). Most of the peptide positions were located in the peptide-binding grooves and seemed to affect antigen presentation. All the existing and novel variants explained approximately 2.37% of the phenotypic variances, while 21.10% was attributed to the variants identified in this study. CONCLUSION: We identified seven novel bi-allelic variants and five polymorphic amino acid positions in HLA-DRbeta1, HLA-DQalpha1, and HLA-A that confer a risk of lung cancer. This finding provides evidence for the substantial contributions of HLA class I and II molecules to lung cancer susceptibility. PMID- 29191592 TI - Adherence to surveillance guidelines in resected NSCLC: Physician compliance and impact on outcomes. AB - BACKGROUND: Resected NSCLC guidelines have varying recommendations on appropriate post-operative surveillance. There is general consensus that patients require follow-up with clinic visits and/or CT scans every 6 months for the first 2 years. This study evaluated compliance with surveillance guidelines and the impact on outcomes. METHODS: The BC Cancer Agency (BCCA) provides cancer control for 4.6 million individuals. Inclusion criteria included referred patients from 2005 to 2010, resected stage Ib/II NSCLC, minimum 2 years follow-up at the BCCA, no prior cancer within 5 years. Retrospective chart review collected baseline parameters, follow up visits, CT imaging, recurrence and death. RESULTS: 479 were referred and 263 were eligible. Baseline characteristics: median age 68, male 52%, current/former/never smoker 38/52/10%, stage Ib/II 51/49%, squamous/non 30%/70%. Adherence to visits and/or CT scans every 6 months in 2 years: clinic visits 77%, CT scans 35%, visit and/or CT 80%. Recurrence rate was 46% at 2 years. Surveillance below vs per/above guidelines; metastatic recurrence 57% vs 79% (p=0.28), curative intent treatment at recurrence 14% vs 9% (p=0.50), palliative systemic treatment given 14% vs 34% (p=0.42), DFS 66.6m vs 37.6m (p<0.001), OS 76.5m vs 37.7m (p<0.001). CONCLUSIONS: Compliance with follow up recommendations for resected NSCLC was 80%. Guideline conformity did not increase the rate of curative treatment at recurrence nor did it increase the proportion of patients treated with palliative chemotherapy. Better adjuvant treatment and surveillance options are needed for resected NSCLC. PMID- 29191593 TI - Outcomes in patients with aggressive or refractory disease from REVEL: A randomized phase III study of docetaxel with ramucirumab or placebo for second line treatment of stage IV non-small-cell lung cancer. AB - OBJECTIVES: The REVEL study demonstrated improved efficacy for patients with advanced non-small cell lung cancer treated with ramucirumab plus docetaxel, independent of histology. This exploratory analysis characterized the treatment effect in REVEL patients who were refractory to prior first-line treatment. MATERIALS AND METHODS: Refractory patients had a best response of progressive disease to first-line treatment. Endpoints included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), quality of life (QoL), and safety. Kaplan-Meier and Cox proportional hazards regression were performed for OS and PFS, and Cochran-Mantel-Haenszel test was used for response. QoL was assessed with the Lung Cancer Symptom Scale. Sensitivity analyses were performed on subgroups of the intent-to-treat population with limited time on first-line therapy. RESULTS: Of 1253 randomized patients in REVEL, 360 (29%) were refractory to first-line treatment. Baseline characteristics were largely balanced between treatment arms. In the control arm, median OS for refractory patients was 6.3 versus 10.3 months for patients not meeting this criterion, demonstrating the poor prognosis of refractory patients. Median OS (8.3 vs. 6.3 months; HR, 0.86; 95% CI, 0.68-1.08), median PFS (4.0 vs. 2.5 months; HR, 0.71; 95% CI, 0.57-0.88), and ORR (22.5% vs. 12.6%) were improved in refractory patients treated with ramucirumab compared to placebo, without new safety concerns or further deteriorating patient QoL. CONCLUSIONS: The effect of ramucirumab in refractory patients is similar to that in the intent-to-treat population. The benefit/risk profile for refractory patients suggests that ramucirumab plus docetaxel is an appropriate treatment option even in this difficult-to-treat population. PMID- 29191594 TI - A phase II trial of carboplatin plus S-1 for elderly patients with advanced non small-cell lung cancer with wild-type epidermal growth factor receptor: The Okayama Lung Cancer Study Group Trial 1202. AB - INTRODUCTION: S-1 is an oral fluoropyrimidine-based combination of tegafur, gimeracil, and oteracil potassium. Although the combination of S-1 with carboplatin is a first-line chemotherapy regimen for advanced non-small cell lung cancer (NSCLC), the efficacy and safety of the regimen in the elderly remain unknown. METHODS: The patient inclusion criteria were previously untreated advanced NSCLC, wild-type epidermal growth factor receptor, aged 70 years or more, and a performance status (PS) of 0-2. The patients received oral S-1 (40mg/m2, twice daily) for 2 weeks and carboplatin (area under the curve: 5) on day 1 every 4 weeks as induction treatment. After four induction cycles, S-1 alone (40mg/m2, twice daily) was administered for 2 weeks every 4 weeks as a maintenance therapy until disease progression. The primary endpoint was the overall response rate (ORR), which was expected to exceed 20%, and the secondary endpoints included the disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and the toxicity profile. The associations between clinical outcomes and expression of genes such as thymidylate synthase and thymidine phosphorylase in the tumors were evaluated. RESULTS: Thirty-three patients were enrolled between March 2013 and June 2015. The median age was 78 (range 70-89) years, and 51.5% had a PS of 0. The ORR was 30.3% (95% confidence interval (CI): 14.6-46.0) and the DCR 57.6% (95% CI: 40.7-74.4). Grade 3/4 toxicities included thrombocytopenia (42.4%), neutropenia (33.3%), and anemia (27.3%). There was one treatment-related death due to aspiration pneumonia following febrile neutropenia. The median PFS and OS were 134days (95% CI: 79 173) and 479days (95% CI: 250-571), respectively. Low thymidine phosphorylase expression was associated with the DCR (P<0.01). CONCLUSION: This study met the predesigned primary endpoint, and the regimen seems to be a favorable treatment option. PMID- 29191595 TI - Phase 2 study of intermittent pulse dacomitinib in patients with advanced non small cell lung cancers. AB - BACKGROUND: Dacomitinib is a second-generation, irreversible epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI). Pre-clinical data suggest that intermittent pulsatile dosing of dacomitinib may result in inhibition of EGFR T790M. METHODS: We evaluated safety, pharmacokinetics and efficacy of intermittent pulsatile dacomitinib in both molecularly unselected patients and patients with lung cancers harboring EGFR T790M (Clinical Trial Registration Number NCT01858389). RESULTS: Thirty-eight patients were treated on study with pulse dacomitinib; sixteen with EGFR T790M in Cohort A and 22 who were not molecularly selected in Cohort B. One patient out of 16 patients in Cohort A had a partial response to study therapy (ORR 6.3%, 95% CI 0.2-30.2%). The median progression-free survival (PFS) in Cohort A was 2.3 months and median PFS in Cohort B was 1.6 months. The adverse event profile was similar to standard daily dose dacomitinib with the most frequent treatment-related toxicities occurring in >20% of patients being diarrhea, rash, stomatitis, nausea, dry skin, paronychia, fatigue, and decreased appetite. CONCLUSION: Intermittent pulsatile dacomitinib is safe and relatively well tolerated but is not effective in patients that harbor EGFR T790M or in unselected patients with non-small cell lung cancer. PMID- 29191596 TI - PD-L1 expression in advanced NSCLC: Insights into risk stratification and treatment selection from a systematic literature review. AB - Tumors can evade immune detection by exploiting inhibitory immune checkpoints such as the programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1) pathway. Antibodies that block this pathway offer a promising new approach to treatment in advanced/metastatic non-small cell lung cancer (NSCLC). A systematic review of the literature was conducted to assess the association of PD-L1 with important patient and disease characteristics, the prognostic significance of PD L1 expressing NSCLC tumors, and the value of PD-L1 as a predictive biomarker of response to anti-PD-1/PD-L1 treatments in advanced/metastatic NSCLC. A total of 35 eligible studies were selected for analysis. Methods used to determine PD-L1 in NSCLC tissue varied considerably; with different PD-L1 antibodies, antibody detection methods, and staining cut-offs. Immunohistochemistry was the most frequent type of PD-L1 assay. Overall, study evidence did not support an association between PD-L1 expression and gender, age, smoking history, tumor histology (adenocarcinoma vs. squamous cell carcinoma), performance status, pathologic tumor grade or EGFR/KRAS/ALK mutational status. In several studies, high PD-L1 expression was associated with shorter survival compared with low expression. Most evidence indicated that patients with high vs. low PD-L1 expression were more likely to experience treatment benefit with anti-PD-1/PD-L1 agents (nivolumab, pembrolizumab, durvalumab, atezolizumab, and avelumab) in advanced NSCLC. Variability in the methods used to determine PD-L1 expression in NSCLC tissue suggests a need for standardized use of well-validated PD-L1 diagnostic assays. Although considerable research links PD-L1 expression in tumors to shorter survival in advanced/metastatic NSCLC, its use as a prognostic factor requires more study. As studies of anti-PD-1/PD-L1 agents continue, PD-L1 is likely to play an important role as a predictive biomarker for selecting patients deriving most benefit from anti-PD-1/PD-L1 monotherapy and directing patients with lower levels of tumor PD-L1 expression (with a high unmet medical need), to alternative treatments, such as combination immunotherapies. PMID- 29191597 TI - Anamorelin for advanced non-small-cell lung cancer with cachexia: Systematic review and meta-analysis. AB - INTRODUCTION: Cancer anorexia-cachexia syndrome (CACS) is characterized by involuntary weight loss. CACS is commonly observed in advanced non-small-cell lung cancer (NSCLC), and it leads to a poor quality of life (QOL). No effective standard treatment exists for this condition. However, anamorelin has reportedly caused improvement in patients with several cancers. MATERIALS AND METHODS: We conducted a quantitative meta-analysis to explore the efficacy of anamorelin for treating CACS in patients with NSCLC. We systematically searched CENTRAL, MEDLINE, EMBASE, CINAHL, and OvidSP. We pooled the data and calculated and compared total body weight (TBW), lean body mass (LBM), overall survival (OS), hand grip strength (HGS), QOL, and adverse events (AEs) between patients treated with anamorelin (anamorelin group) and those not (placebo group). RESULT: Six randomized controlled trials included 1641 patients with NSCLC. Both TBW and LBM were significantly increased in the anamorelin group compared to the placebo group (mean differences [MD] 1.78, 95%CI: 1.28-2.28, p<0.00001; MD 1.10, 95%CI: 0.35-1.85, p=0.004, respectively). The groups showed no difference in OS or HGS (hazard ratio 0.99, 95%CI: 0.85-1.14, p=0.84; MD 0.52, 95% CI: -0.09-1.13, p=0.09, respectively). Anamorelin significantly improved the QOL (standardized MD 0.19, 95%CI: 0.08-0.30, p=0.0006). The frequency of any AEs and grade 3 or 4 AEs were not significantly different between groups (risk ratio[RR] 1.03, 95%CI: 0.95 1.10, p=0.49; RR 0.86, 95%CI: 0.48-1.54, p=0.62). CONCLUSION: This analysis demonstrated that anamorelin represents a promising treatment option for CACS in patients with advanced NSCLC. PMID- 29191598 TI - Prospective analysis of patient reported symptoms and quality of life in patients with incurable lung cancer treated in a rapid access clinic. AB - INTRODUCTION: The Vancouver Rapid Access (VARA) clinic was designed to provide palliative radiotherapy and holistic care to patients with incurable lung cancer. Analysis of the pilot phase demonstrated improved radiotherapy wait-times and access to supportive services compared to standard practice. This study aims to prospectively assess the impact of the clinic on patient reported symptoms and quality of life. MATERIALS AND METHODS: Patient assessments are completed at baseline and by a telephone follow up four-weeks later using Likert scales adapted from the Edmonton Symptom Assessment System (scale 0-10) and European Organization for Research and Treatment of Cancer questionnaires (scale 1-4). Patient reported outcomes at follow-up are compared to baseline using wilcoxon signed-rank test for categorical variables and paired sample t-test for continuous variables. RESULTS: Baseline data was collected on 125 patients, 109 received palliative radiotherapy (87%). At the 4 week follow up, 22 patients had died. Seventy-one of the remaining 103 patients completed the follow-up questionnaire, resulting in a 69% response rate among survivors. The mean patient reported overall health score, improved from 4.8 to 6.1 (p<0.01). All respiratory symptoms except chest pain (p=0.06) were associated with a statistically significant improvement after the clinic, whereas all respiratory symptoms improved post radiotherapy. Mean bone pain scores decreased from 5.5 to 2.7 (p<0.01). Assessment of symptoms secondary to brain metastases is limited by small patient numbers. CONCLUSION: The VARA clinic provides timely access to palliative radiotherapy and supportive services resulting in improved patient reported outcomes. Despite a high symptom and disease burden, patients report improved overall health and palliation of respiratory symptoms and bony pain. The studies completed on the VARA clinic to date, continue to support its value in our center. PMID- 29191599 TI - Limited mutagenicity of electronic cigarettes in mouse or human cells in vitro. AB - OBJECTIVES: Electronic cigarettes (e-cig), which are promoted as safe alternatives to tobacco cigarettes or as aides to smoking cessation, are becoming increasingly popular among adult chronic smokers and adolescents experimenting with tobacco products. Despite the known presence of toxicants and carcinogens in e-cig liquid and vapor, the possible carcinogenic effects of e-cig use in humans are unknown. MATERIALS AND METHODS: We have utilized two validated in vitro model systems to investigate whether e-cig vapor induces mutation in mouse or human cells. We have exposed transgenic mouse fibroblasts in vitro to e-cig vapor extracts prepared from three popular brands, and determined the induction of mutagenesis in a reporter gene, the cII transgene. Furthermore, we have treated the pSP189 plasmid with e-cig vapor extract, transfected human fibroblast cells with the e-cig-treated plasmid, and screened for the induced mutations in the supF gene. RESULTS AND CONCLUSION: We observed no statistically significant increases in relative mutant frequency in the cII transgene or supF gene in the e cig treated mouse or human cells, respectively. Our data indicate that e-cig vapor extracts from the selected brands and at concentrations tested in this study have limited mutagenicity in both mouse and human cells in vitro. PMID- 29191601 TI - Clinical significance of tumor cavitation in surgically resected early-stage primary lung cancer. AB - OBJECTIVES: The prognostic impact of tumor cavitation is unclear in patients with early-stage primary lung cancer. The aim of the present study was to examine the clinicopathological features and prognoses of patients with pathological stage I IIA (p-stage I-IIA) primary lung cancers harboring tumor cavitation. This study was conducted according to the eighth edition of the TNM classification for lung cancer. MATERIALS AND METHODS: We examined 602 patients with p-stage I-IIA primary lung cancer out of 890 patients who underwent pulmonary resection from January 2007 through March 2014 and searched for the presence of tumor cavitation, which is defined as the presence of air space within the primary tumor. RESULTS: A total of 59 out of the 602 patients had tumor cavitation (10%). Compared with patients without tumor cavitation, those with tumor cavitation had a significantly higher frequency of the following characteristics: high serum carcinoembryonic antigen (CEA) level (>=5ng/ml, p=0.027), interstitial pneumonia (p=0.0001), high SUVmax value on FDG-PET scan (>=4.2, p=0.023), tumors located in the lower lobe (p=0.024), large tumor size (>3cm, p=0.002), vascular invasion (66% vs 17%, p<0.0001) and non-adenocarcinoma histology (p=0.025). The overall survival period of patients with tumor cavitation was significantly shorter than that of patients without tumor cavitation (log-rank test: p<0.0001, 5-year OS rate: 56% vs 81%). Tumor cavitation was found to be an independent and significant factor associated with poor prognosis in the multivariate analysis (hazard ratio: 1.76, 95% confidence interval: 1.02-3.10, p=0.042). CONCLUSIONS: Tumor cavitation is an independent factor for poor prognosis in patients with resected p-stage I-IIA primary lung cancer. Based on our analyses, patients with tumor cavitation should be regarded as a separate cohort that requires more intensive follow-up. PMID- 29191600 TI - Mig-6 deficiency cooperates with oncogenic Kras to promote mouse lung tumorigenesis. AB - OBJECTIVES: Lung cancer is the leading cause of cancer related deaths worldwide and mutation activating KRAS is one of the most frequent mutations found in lung adenocarcinoma. Identifying regulators of KRAS may aid in the development of therapies to treat this disease. The mitogen-induced gene 6, MIG-6, is a small adaptor protein modulating signaling in cells to regulate the growth and differentiation in multiple tissues. Here, we investigated the role of Mig-6 in regulating adenocarcinoma progression in the lungs of genetically engineered mice with activation of Kras. MATERIALS AND METHODS: Using the CCSPCre mouse to specifically activate expression of the oncogenic KrasG12D in Club cells, we investigated the expression of Mig-6 in CCSPCreKrasG12D-induced lung tumors. To determine the role of Mig-6 in KrasG12D-induced lung tumorigenesis, Mig-6 was conditionally ablated in the Club cells by breeding Mig6f/f mice to CCSPCreKrasG12D mice, yielding CCSPCreMig-6d/dKrasG12D mice (Mig-6d/dKrasG12D). RESULTS: We found that Mig-6 expression is decreased in CCSPCreKrasG12D-induced lung tumors. Ablation of Mig-6 in the KrasG12D background led to enhanced tumorigenesis and reduced life expectancy. During tumor progression, there was increased airway hyperplasia, a heightened inflammatory response, reduced apoptosis in KrasG12D mouse lungs, and an increase of total and phosphorylated ERBB4 protein levels. Mechanistically, Mig-6 deficiency attenuates the cell apoptosis of lung tumor expressing KRASG12D partially through activating the ErbB4 pathway. CONCLUSIONS: In summary, Mig-6 deficiency promotes the development of KrasG12D-induced lung adenoma through reducing the cell apoptosis in KrasG12D mouse lungs partially by activating the ErbB4 pathway. PMID- 29191602 TI - LKB1/STK11 mutations in non-small cell lung cancer patients: Descriptive analysis and prognostic value. AB - BACKGROUND: LKB1/STK11 (STK11) is among the most inactivated tumor-suppressor genes in non-small cell lung cancer (NSCLC). While evidence concerning the biologic role of STK11 is accumulating, its prognostic significance in advanced NSCLC has not been envisaged yet. MATERIALS AND METHODS: This retrospective analysis included consecutive NSCLC patients with available STK11 information who underwent a platinum-based chemotherapy. STK11 mutational status was correlated to clinico-pathological and mutational features. Kaplan-Meier and Cox models were used for survival curves and multivariate analyses, respectively. RESULTS: Among the 302 patients included, 267 (89%) were diagnosed with stage IIIB/IV NSCLC and 25 (8%) harbored a STK11 mutation (STK11mut). No statistical differences were observed between STK11 status and clinico-pathological variables. We detected a significant correlation between STK11 and KRAS status (p=0.008); among the 25 STK11mut patients, 13 (52%) harbored a concomitant KRAS mutation. Overall survival (OS) was shorter for STK11mut (median OS=10.4months) compared to wild type patients (STK11wt; median OS=17.3months) in univariate analysis (p=0.085). STK11 status did not impact upon OS in multivariate analysis (p=0.45) and non significant results were observed for progression-free survival. The co occurrence of KRAS and STK11 mutations suggest a trend toward detrimental effect in OS (p=0.12). CONCLUSIONS: In our cohort enriched for advanced NSCLC patients who received platinum-based chemotherapy, STK11 mutations were not specifically associated with clinico-pathological features and they did not impact upon survival. We confirm the positive correlation between STK11 and KRAS mutations. The co-occurrence of KRAS and STK11 mutations could label a more aggressive molecular subtype of NSCLC. PMID- 29191603 TI - Serum lipid profile discriminates patients with early lung cancer from healthy controls. AB - OBJECTIVES: The role of a low-dose computed tomography lung cancer screening remains a matter of controversy due to its low specificity and high costs. Screening complementation with blood-based biomarkers may allow a more efficient pre-selection of candidates for imaging tests or discrimination between benign and malignant chest abnormalities detected by low-dose computed tomography (LD CT). We searched for a molecular signature based on a serum lipid profile distinguishing individuals with early lung cancer from healthy participants of the lung cancer screening program. MATERIALS AND METHODS: Blood samples were collected from 100 patients with early stage lung cancer (including 31 screen detected cases) and from a matched group of 300 healthy participants of the lung cancer screening program. MALDI-ToF mass spectrometry was used to analyze the molecular profile of lipid-containing organic extract of serum samples in the 320 1000Da range. RESULTS: Several components of the serum lipidome were detected, with abundances discriminating patients with early lung cancer from high-risk smokers. An effective cancer classifier was built with an area under the curve of 0.88. Corresponding negative predictive value was 98% and a positive predictive value was 42% when the classifier was tuned for maximum negative predictive value. Furthermore, the downregulation of a few lysophosphatidylcholines (LPC18:2, LPC18:1 and LPC18:0) in samples from cancer patients was confirmed using a complementary LC-MS approach (a reasonable cancer discrimination was possible based on LPC18:2 alone with 25% total weighted error of classification). CONCLUSIONS: Lipid-based serum signature showed potential usefulness in discriminating early lung cancer patients from healthy individuals. PMID- 29191604 TI - MHC class II expression in lung cancer. AB - BACKGROUND: Immunotherapy is an exciting development in lung cancer research. In this study we described major histocompatibility complex (MHC) Class II protein expression in lung cancer cell lines and patient tissues. METHODS: We studied MHC Class II (DP, DQ, DR) (CR3/43, Abcam) protein expression in 55 non-small cell lung cancer (NSCLC) cell lines, 42 small cell lung cancer (SCLC) cell lines and 278 lung cancer patient tissues by immunohistochemistry (IHC). RESULTS: Seven (12.7%) NSCLC cell lines were positive for MHC Class II. No SCLC cell lines were found to be MHC Class II positive. We assessed 139 lung cancer samples available in the Hirsch Lab for MHC Class II. There was no positive MHC Class II staining on SCLC tumor cells. MHC Class II expression on TILs in SCLC was significantly lower than that on TILs in NSCLC (P<0.001). MHC Class II was also assessed in an additional 139 NSCLC tumor tissues from Medical University of Gdansk, Poland. Patients with positive staining of MHC Class II on TILs had longer regression free survival (RFS) and overall survival (OS) than those whose TILs were MHC Class II negative (2.980 years, 95% CI 1.628-4.332 vs. 1.050 years, 95% CI 0.556 1.554, P=0.028) (3.230 years, 95% CI 2.617-3.843 vs. 1.390 years, 95% CI 0.629 2.151, P=0.014). CONCLUSIONS: MHC Class II was expressed both in NSCLC cell lines and tissues. However, MHC Class II was not detected in SCLC cell lines or tissue tumor cells. MHC Class II expression was lower on SCLC TILs than on NSCLC TILs. Loss of expression of MHC Class II on SCLC tumor cells and reduced expression on SCLC TILs may be a means of escaping anti-cancer immunity. Higher MHC Class II expression on TILs was correlated with better prognosis in patients with NSCLC. PMID- 29191605 TI - Inhibition of protein phosphatase 5 suppresses non-small cell lung cancer through AMP-activated kinase activation. AB - OBJECTIVES: Non-small cell lung cancer (NSCLC) continues to be the top cause of cancer death. To improve the treatment of lung cancer, there is necessity to identify novel oncogenes and investigate their effects on lung carcinogenesis. Protein phosphatase 5 (PP5) has long been known to regulate stress-induced apoptosis and cell proliferation. Recently, PP5 has been found overexpressed and emerged as a viable therapeutic target in various human cancers, but its role in NSCLC remains elusive. MATERIALS AND METHODS: The expression of PP5 in NSCLC cell lines (A549, H358, and H460) and human tumor samples were examined. Protein phosphatase inhibitors, cantharidin and norcantharidin, were used as proof-of concept compounds to investigate the pathological function of PP5 in NSCLC. Apoptosis and cellular signaling were analyzed. In vivo efficacy was determined in nude mice with H460 xenograft. RESULTS AND CONCLUSION: We found that PP5 was more highly expressed in human lung tumor samples than in adjacent normal tissues. Overexpression of PP5 promoted cell proliferation, colony formation, and sphere-forming ability of A549 cells. Inhibition of PP5 phosphatase activity by cantharidin induced significant apoptosis and upregulated AMP-activated protein kinase (AMPK) signaling. Importantly, we found that PP5-mediated dephosphorylation of AMPK determines the in vitro anti-NSCLC effects of cantharidin. Consistent with our in vitro data, PP5 inhibition suppressed H460 tumor growth and upregulated p-AMPK in tumor samples. Our results demonstrate that PP5 inhibition suppresses tumor growth via activating AMPK signaling. Targeting oncogenic PP5 represents an attractive therapeutic strategy for treating lung cancer. PMID- 29191606 TI - Response rates to single-agent chemotherapy after exposure to immune checkpoint inhibitors in advanced non-small cell lung cancer. AB - INTRODUCTION: Exploratory analysis of clinical trials in various tumor types have demonstrated potential improvements in overall response rate (ORR) to chemotherapy after exposure to vaccine-based immunotherapy. The objective of this retrospective study was to determine if single-agent chemotherapy (3rd-line or beyond) would yield improved ORR when given after exposure to programmed death (ligand)1 inhibitors (anti-PD1) in metastatic non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: We queried the Thoracic GEMINI database of MD Anderson Cancer Center for patients treated between 06/12 and 11/16 who received at least one single-agent chemotherapy as 3rd-line or beyond, following progression after platinum-based chemotherapy and anti-PD1. We evaluated efficacy outcomes to each therapy, including ORR by RECIST version 1.1, progression-free survival (PFS), and overall survival (OS). RESULTS: Out of 306 anti-PD1-treated patients registered in the database, 28 met eligibility criteria - 54% were male, median age was 66 years, 82% had adenocarcinoma, and 71% were former/current smokers. The anti-PD1 and single-agent chemotherapy most commonly used were nivolumab (86%) and docetaxel (50%), respectively. ORR to single-agent chemotherapy after exposure to anti-PD1 was 39% (11/28 patients, 8 confirmed). In contrast, ORR to first-line chemotherapy in this cohort was 37%. Liver metastasis was the only factor associated with response to single-agent chemotherapy on univariate analysis (p<0.05). CONCLUSION: In NSCLC patients, the confirmed ORR to single agent chemotherapy after immunotherapy exposure was higher as compared to historical data from the pre-anti-PD1 era, and approached ORR to first-line platinum-based chemotherapy. Further investigation of a possible immunotherapy induced chemosensitization effect is warranted. PMID- 29191607 TI - PIK3CA mutation as a distinctive genetic feature of non-small cell lung cancer with chronic obstructive pulmonary disease: A comprehensive mutational analysis from a multi-institutional cohort. AB - OBJECTIVES: Non-small cell lung cancer (NSCLC) and chronic obstructive pulmonary disease (COPD) have been proposed to have a mutual developmental mechanism, but their association has not been fully understood. We aimed to examine the association of the mutational landscape of NSCLC with co-morbid COPD. MATERIALS AND METHODS: A total of 197 surgical specimens of early stage NSCLC were retrospectively collected from two independent sources, namely, the Japan Molecular Epidemiology for Lung Cancer Study and the Osaka City University Hospital cohort from 2010 to 2013. COPD and its severity were defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines and grading system. For molecular profiling of NSCLC patients with COPD, the extracted DNAs were deep-sequenced using next generation sequence technologies for somatic mutations in a maximum 72 cancer-associated genes. Logistic regression analysis was performed to evaluate the impact of COPD on the somatic mutations. RESULTS: The COPD group (n=77), including 56 GOLD 1 and 21 GOLD 2 or 3 patients, had 58 squamous cell lung carcinoma (SCC) cases and 19 adenocarcinoma cases. The non-COPD group (n=120) had 53 SCC cases, 64 adenocarcinoma cases, and three cases with other histology. The frequency of PIK3CA mutation was significantly higher in the COPD group than in the non-COPD group (10.4% vs. 1.7%, p=0.015). Meanwhile, NFE2L2 mutation was observed only in SCC cases, with no difference in the frequency between the two groups (17.2% vs. 17.0%). In the multivariate logistic regression model with consideration for COPD status, age, smoking dose, pathological stage, and histology, significantly more PIK3CA mutation was observed in the presence of COPD (odds ratio=5.31, 95% CI: 1.03 27.29, p=0.046). CONCLUSIONS: PIK3CA mutation is a distinctive genetic feature of NSCLC with COPD, regardless of age, smoking dose, pathological stage, and histology. PMID- 29191608 TI - A fully digital approach to replicate functional and aesthetic parameters in implant-supported full-arch rehabilitation. AB - PURPOSE: The aim of this technical procedure was to use a fully digital technique (FDT) for full-arch implant support rehabilitation. The FDT was used to transfer the provisional restoration parameters to definitive restorations using intraoral scanners. METHODS: Three sets of digital impressions were obtained. Through the first set, standard tessellation language 1 (STL1), provisional restorations screwed to implants and the surrounding gingival tissue was captured. STL2 consisted of intraoral scans of standardized scanbodies screwed to implants to collect 3D positioning data of implants. STL3 included the digital impression of provisional restoration out of the mouth in order to capture the gingival architecture and the peri-implant soft tissue that was not possible to transfer with the previous impressions. STL1, STL2, and STL3 were combined using computer aided design (CAD) functions into a single file, STL4. Thus, STL4 contained information on the 3D implant positions, soft tissue architectures, occlusal relationships, correct occlusal vertical dimension and aesthetic features. Using STL4, the master models with implant analogues were 3D printed. Computer-aided design and computer-aided manufacturing milled (CAD/CAM-milled) aluminium bars and a resin prototype were produced to test the accuracy and the functional and aesthetic parameters. Titanium frameworks were digitally designed using STL4, milled using CAD/CAM, and finalized with pink resin and resin teeth. CONCLUSION: The FDT provided an effective fully digital protocol to capture all information for provisional full-arch implant restorations using an intraoral scanner and transfer that information to definitive restorations. PMID- 29191609 TI - Accuracy of various impression materials and methods for two implant systems: An effect size study. AB - PURPOSE: An accurate impression is required for implant treatment. The aim of this in-vitro study was to determine the effect size of the impression material/method, implant system and implant angulation on impression transfer precision. METHODS: An upper jaw model with three BEGO and three Straumann implants (angulations 0 degrees , 15 degrees , 20 degrees ) in the left and right maxilla was used as a reference model. One polyether (Impregum Penta) and two polyvinyl siloxanes (Flexitime Monophase/Aquasil Ultra Monophase) were examined with two impression techniques (open and closed tray). A total of 60 impressions were made. A coordinate measurement machine was used to measure the target variables for 3D-shift, implant axis inclination and implant axis rotation. All the data were subjected to a four-way ANOVA. The effect size (partial eta-squared [eta2P]) was reported. RESULTS: The impression material had a significant influence on the 3D shift and the implant axis inclination deviation (p values=.000), and both factors had very large effect sizes (3D-shift [eta2P]=.599; implant axis inclination [eta2P]=.298). Impressions made with polyvinyl siloxane exhibited the highest transfer precision. When the angulation of the implants was larger, more deviations occurred for the implant axis rotational deviation. The implant systems and impression methods showed partially significant variations (p-values=.001-.639) but only very small effect sizes (eta2P=.001-.031). CONCLUSIONS: The impression material had the greatest effect size on accuracy in terms of the 3D shift and the implant axis inclination. For multiunit restorations with disparallel implants, polyvinyl siloxane materials should be considered. In addition, the effect size of a multivariate investigation should be reported. PMID- 29191610 TI - Incidence and prevention of infective endocarditis and bacteraemia after transcatheter aortic valve implantation in a French university hospital: a retrospective study. AB - Infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI) is a rare but severe complication. Among 326 patients who underwent TAVI at Grenoble Alpes University Hospital, six (1.8%) cases of IE and 11 (3.4%) cases of bacteraemia were identified. No cases of IE were linked to the intervention; one was due to Staphylococcus aureus despite a screening and targeted decolonization strategy. This underscores the need for randomized studies to evaluate the benefit and cost-effectiveness of this policy. PMID- 29191611 TI - Activation of peroxymonosulfate using drinking water treatment residuals for the degradation of atrazine. AB - Drinking water treatment residuals (WTRs) are safe byproducts of water treatment plants containing iron. This work studies the degradation of atrazine (ATZ) by WTR-catalyzed peroxymonosulfate (PMS) in aqueous solutions. Factors that affect the catalytic performance (the PMS concentration, catalyst dose, initial solution pH, reaction temperature and water matrix species) were investigated. The results show that the catalytic degradation efficiency of ATZ increases with the increase in PMS concentration and temperature, whereas a higher content of WTRs results in lower removal efficiency because of the quenching effect and negative effect of high pH. For an initial solution pH of 3 and 5, 94.1% and 87.4% of ATZ degradation can be achieved within 6h, whereas the value is only 26% for pH of 7. The production of sulfate radicals (SO4-) and hydroxyl radicals (OH) was confirmed by classic radical quenching and electron spin resonance (ESR) tests. Based on the GC-MS and LC-MS results, the main degradation pathways of ATZ may contain dealkylation, dechlorination-hydroxylation, and alkyl chain oxidation processes. In addition to the ATZ removal ability, the WTRs/PMS system can simultaneously remove phosphorus. This article provides a new idea for wastewater treatment and usage of WTRs as a resource. PMID- 29191612 TI - In vivo activity of fluconazole/tetracycline combinations in Galleria mellonella with resistant Candida albicans infection. AB - OBJECTIVES: Treatment of azole-resistant Candida albicans infections continues to pose significant challenges. With limited options of licensed agents, drug combinations may be a practical treatment alternative. In our previous studies, the combinations minocycline/fluconazole (MINO/FLC) and doxycycline/fluconazole (DOXY/FLC) shown synergistic effects in vitro. It is necessary to explore their appropriate dosage, potential toxicity and in vivo efficacy. METHODS: The Galleria mellonella infection model was employed to study the in vivo efficacy of MINO/FLC and DOXY/FLC by survival analysis, quantification of C. albicans fungal burden and histological studies. RESULTS: The survival rates of G. mellonella larvae infected with lethal doses of resistant C. albicans CA10 increased significantly when treated with the drug combinations compared with FLC treatment alone, and the fungal burden was reduced by almost four-fold. The histopathological study showed that fewer infected areas in larvae were observed and the destructive degree was less when larvae were exposed to the drug combinations. CONCLUSIONS: These findings suggest that combination of a tetracycline antibiotic (MINO or DOXY) with FLC has antifungal activity against azole-resistant C. albicans in vivo. This is in agreement with several previous in vitro studies and provides preliminary in vivo evidence that such a combination might be useful therapeutically. PMID- 29191613 TI - Abnormal biventricular performance in asymptomatic adolescents late after repaired Tetralogy of Fallot: Combined two-dimensional speckle tracking and three dimensional echocardiography study. AB - BACKGROUND: The aim of this prospective study was to assess biventricular performance in asymptomatic adolescents with repaired tetralogy of Fallot (TOF) using 2D speckle tracking and real time 3D echocardiography simultaneously. METHODS: We studied 31 patients with repaired TOF (M/F: 22/9, age: 16.1 +/- 6.1 yrs) who had history of cardiac surgery with mean follow-up duration of 12.8 years, and 32 age- and sex-matched normal individuals (M/F: 23/9, age: 16.6 +/- 5.1 yrs). All subjects underwent speckle tracking and 3D echocardiography, electrocardiogram, treadmill, and blood sampling for measurement of brain natriuretic peptide (BNP). RESULTS: Compared to the control group, the TOF group had higher BNP level (31.8 +/- 21.4 vs 14.1 +/- 12.4 pg/ml, p < 0.01), lower peak oxygen consumption (8.4 +/- 1.7 vs 9.9 +/- 1.6 ml/kg/min, p < 0.05), and longer QRS duration (126 +/- 30 vs 82 +/- 9 ms, p < 0.01). Patients with repaired TOF had significantly impaired right ventricle (RV) global and all six regional longitudinal strain and strain rate than normal controls. Left ventricle (LV) global and mainly apical regional longitudinal strain and strain rate were reduced in patients with repaired TOF. There was a significant correlation of global longitudinal strain (r = 0.456, p = 0.01) and global time to peak longitudinal strain (r = 0.484, p < 0.01) between LV and RV in patients with repaired TOF. In terms of 3D echo cardiographic volume data, patients with repaired TOF had lower LV stroke volume index (p < 0.05), but higher RV end diastolic volume index (p < 0.01), RV end systolic volume index (p < 0.01), RV stroke volume index (p < 0.01), and pulmonary regurgitation fraction (p < 0.01) than normal controls. CONCLUSION: Our results suggest asymptomatic adolescents with repaired TOF had abnormal biventricular myocardial performance, as demonstrated by combined 2D speckle-tracking and 3D echocardiography. The implications of these findings for management of adolescents late after repaired TOF remain to be determined. PMID- 29191614 TI - Accuracy of a Cone-Beam CT Virtual Parenchymal Perfusion Algorithm for Liver Cancer Targeting during Intra-arterial Therapy. AB - PURPOSE: To evaluate accuracy of virtual parenchymal perfusion (VPP) algorithm developed for targeting liver cancer during intra-arterial therapy (IAT) using cone-beam CT guidance. MATERIALS AND METHODS: VPP was retrospectively applied to 15 patients who underwent IAT for liver cancer. Virtual territory (VT) was estimated after positioning a virtual injection point on nonselective dual-phase (DP) cone-beam CT images acquired during hepatic arteriography at the same position chosen for selective treatment. Targeted territory (TT) was used as the gold standard and was defined by parenchymal phase enhancement of selective DP cone-beam CT performed before treatment start. Qualitative evaluation of anatomic conformity between VT and TT was performed using a 3-rank scale (poor, acceptable, excellent) by 3 double-blinded readers. VT and TT were also quantitatively compared using spatial overlap-based (Dice similarity coefficient [DSC], sensitivity, and positive predictive value), distance-based (mean surface distance [MSD]), and volume-based (absolute volume error and correlation between pairwise volumes) metrics. Interreader agreement was evaluated for the 2 evaluation methods. RESULTS: Eighteen DP cone-beam CT scans were performed. Qualitative evaluation showed excellent overlap between VT and TT in 88.9%-94.4%, depending on the readers. DSC was 0.78 +/- 0.1, sensitivity was 80%, positive predictive value was 83%, and MSD was 5.1 mm +/- 2.4. Absolute volume error was 15%, and R2 Pearson correlation factor was 0.99. Interreader agreement was good for both qualitative and quantitative evaluations. CONCLUSIONS: VPP algorithm is accurate and reliable in identification of liver arterial territories during IAT using cone-beam CT guidance. PMID- 29191615 TI - Percutaneous Mitral Valve Technology: What Is on the Horizon? AB - Mitral valve disease is common, with mitral regurgitation (MR) being the most frequent pathology. The etiology of MR is diverse, but, if left untreated, MR results in left ventricular (LV) volume overload, leading to remodeling, dilation of the LV, pulmonary hypertension, heart failure, and death. Mitral regurgitation is a high-risk diagnosis, yet a minority of symptomatic patients are referred for discussion of surgical treatment options. Percutaneous repair options are under development to address this clinical need and emphasize correction of the underlying anatomical pathology to restore mitral valve coaptation. Transcatheter mitral valve replacement is in the early stages of development and may prove safe and effective in certain patient populations. Investigational devices are challenging our current thinking about the management of mitral valve disease, and it will be the task of the multidisciplinary Heart Team to determine the right device for the right pathology.

PMID- 29191618 TI - Is "As Good" Good Enough? PMID- 29191619 TI - Lung Cancer Screening in the Post-National Lung Screening Trial Era: Applying Screening in the Real World. AB - The National Lung Screening Trial established a survival benefit for lung cancer screening using low-dose computed tomography. In the wake of this trial several international bodies now recommend lung cancer screening. However, three main questions remain unanswered: Who is the optimal population for screening? How often should they be screened? For how long should screening be continued? We examine the results of the available randomized trials to address these questions. PMID- 29191620 TI - Genetic Alterations in Primary Acral Melanoma and Acral Melanocytic Nevus in Korea: Common Mutated Genes Show Distinct Cytomorphological Features. AB - Acral melanoma occurring on the palms, soles, and nails is the most common subtype of cutaneous melanoma in Asians. Genetic alterations in acral melanoma and acral melanocytic nevus are not well known. We performed next-generation sequencing and evaluated the correlations between genetic information and the clinicopathologic characteristics from 85 Korean patients with acral melanocytic neoplasms. Of the 64 patients with acral melanoma, most had lesions at the T2 stage or higher, and the heel was the most common anatomical site of melanoma (n = 34 [53.1%]). The five most common mutations were BRAF (22 [34.4%]), NRAS (14, [21.9%]), NF1 (11, [17.2%]), GNAQ (12, [17.2%]), and KIT (7, [10.9%]). In the 21 acral melanocytic nevi, those five gene mutations were also common. Copy number variations were also frequently detected in 75% of acral melanomas and 47.6% of acral melanocytic nevi, and amplification was more common than deletion in both lesions. BRAF mutation was associated with round epithelioid cells and NRAS and NF1 mutations with bizarre cells. NF1 and GNAQ mutations showed elongated and spindle cells with prominent dendrites in acral melanomas. KIT mutations were common in amelanotic acral melanoma. This study suggests that common mutated genes are associated with distinct cytomorphological features in acral melanocytic lesions. PMID- 29191621 TI - Propionibacterium acnes Induces Autophagy in Keratinocytes: Involvement of Multiple Mechanisms. AB - Propionibacterium acnes is a dominant member of the cutaneous microbiota. Herein, we evaluate the effects of different P. acnes strains and propionic acid on autophagy in keratinocytes. Our results showed that P. acnes strain 889 altered the architecture of the mitochondrial network; elevated the levels of microtubule associated protein 1 light chain 3B-II, Beclin-1, and phospho-5'-adenosine monophosphate-activated protein kinase alpha; stimulated autophagic flux; facilitated intracellular redistribution of microtubule-associated protein 1 light chain 3B; increased average number of autophagosomes per cell; and enhanced development of acidic vesicular organelles in the HPV-KER cell line. Propionic acid increased the level of phospho-5'-adenosine-monophosphate-activated protein kinase alpha, enhanced lipidation of microtubule-associated protein 1 light chain 3B, stimulated autophagic flux, and facilitated translocation of microtubule associated protein 1 light chain 3B into autophagosomes in HPV-KER cells. P. acnes strains 889 and 6609 and heat-killed strain 889 also stimulated autophagosome formation in primary keratinocytes to varying degrees. These results indicate that cell wall components and secreted propionic acid metabolite of P. acnes evoke mitochondrial damage successively, thereby triggering 5' adenosine-monophosphate-activated protein kinase-associated activation of autophagy, which in turn facilitates the removal of dysfunctional mitochondria and promotes survival of keratinocytes. Thus, we suggest that low-level colonization of hair follicles with noninvasive P. acnes strains, by triggering a local increase in autophagic activity, might exert a profound effect on several physiological processes responsible for the maintenance of skin tissue homeostasis.

AB - The present study demonstrates the scale-eating behavior of a siluroid catfish, Pachypterus khavalchor, and the role of its oral structure and bacterial endosymbionts in shaping this lepidophagous habit. Scale-eating behavior in P. khavalchor was studied using a series of behavioral experiments. P. khavalchor was found to feed only on the scales of live fish and never of dead fish, even after 72h of starvation. It was nocturnal in habit and attacked all species that were used as prey. Attacking behavior showed extensive chasing of prey species followed by a powerful random strike at the flank or close to the caudal region in posterior oblique position. After a strike, P. khavalchor was found to immediately turn back and pick up the falling dislodged scales. SEM analysis of oral structures of P. khavalchor revealed three different types of teeth arranged in specific order on the upper jaw, lower jaw and pharyngeal region that could facilitate their lepidophagous habit. Teeth of upper and lower jaws are likely to help in dislodging the scales and pharyngeal teeth may help to engulf the scales. Gut microflora analysis and enzyme assay revealed two isolates, namely Bacillus pumilus and Bacillus licheniformis, which were positive for chitinase production. These two isolates were found to be capable of producing chitinase indicating that they are likely to be involved in the digestion of chitin-rich scales in the host fish gut. An in vitro scale degradation assay further strengthens the results since both isolates were found to be efficient in chitinase production and degradation of scales. PMID- 29191623 TI - Diversity out of simplicity: interaction behavior of land planarians with co occurring invertebrates. AB - Land planarians have a simple anatomy and simple behavioral repertoire in relation to most bilaterian animals, which makes them adequate for the study of biological processes. In this study, we investigate the behavior of land planarians during interaction events with other invertebrates found in the same environment. We observed 16 different behavioral units, including seven different capture behaviors and three different prey ingestion behaviors. The capture behavior varied from very simple, such as simply covering the prey with the body, to more complex ones, including two forms of tube formation that are described for the first time. In general, the capture behaviors were similar among different predators but different for different prey. Similarly, prey ingestion type was more related to prey type than to predator species, with small soft prey being swallowed without fragmentation, large prey being crushed, and prey with a hard skeleton being perforated. Considering that land planarians face limitations due to their lack of efficient ways to retain water, thus being highly dependent on a moist environment, the set of behaviors shown by them in this study was considerably rich, especially concerning strategies to capture prey. PMID- 29191624 TI - Phosphate Kinetic Models in Hemodialysis: A Systematic Review. AB - BACKGROUND: Understanding phosphate kinetics in dialysis patients is important for the prevention of hyperphosphatemia and related complications. One approach to gain new insights into phosphate behavior is physiologic modeling. Various models that describe and quantify intra- and/or interdialytic phosphate kinetics have been proposed, but there is a dearth of comprehensive comparisons of the available models. The objective of this analysis was to provide a systematic review of existing published models of phosphate metabolism in the setting of maintenance hemodialysis therapy. STUDY DESIGN: Systematic review. SETTING & POPULATION: Hemodialysis patients. SELECTION CRITERIA FOR STUDIES: Studies published in peer-reviewed journals in English about phosphate kinetic modeling in the setting of hemodialysis therapy. PREDICTOR: Modeling equations from specific reviewed studies. OUTCOMES: Changes in plasma phosphate or serum phosphate concentrations. RESULTS: Of 1,964 nonduplicate studies evaluated, 11 were included, comprising 9 different phosphate models with 1-, 2-, 3-, or 4 compartment assumptions. Between 2 and 11 model parameters were included in the models studied. Quality scores of the studies using the Newcastle-Ottawa Scale ranged from 2 to 11 (scale, 0-14). 2 studies were considered low quality, 6 were considered medium quality, and 3 were considered high quality. LIMITATIONS: Only English-language studies were included. CONCLUSIONS: Many parameters known to influence phosphate balance are not included in existing phosphate models that do not fully reflect the physiology of phosphate metabolism in the setting of hemodialysis. Moreover, models have not been sufficiently validated for their use as a tool to simulate phosphate kinetics in hemodialysis therapy. PMID- 29191625 TI - Impact of Diabetes Mellitus on the Association of Vascular Disease Before Transplantation With Long-term Transplant and Patient Outcomes After Kidney Transplantation: A Population Cohort Study. AB - BACKGROUND: Advances in kidney transplantation have led to considerable improvements in short-term transplant and patient outcomes, but there are few data regarding long-term transplant outcomes in patients with vascular comorbid conditions. This study examined the association of vascular disease before transplantation with transplant and patient survival after transplantation and evaluated whether this association was modified by diabetes. STUDY DESIGN: All deceased donor kidney transplant recipients recorded in the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) for 1990 to 2012. PREDICTOR: Vascular disease burden. OUTCOMES: All-cause mortality and overall transplant loss. Potential interactions between diabetes and vascular disease for mortality and transplant loss were assessed using 2-way interaction terms. RESULTS: Of 7,128 recipients with 58,120 patient-years of follow-up, 854 (12.0%) and 263 (3.7%) had vascular diseases at 1 and 2 or more sites, respectively. Overall survival for recipients without vascular disease 15 years after transplantation was 65% compared with 35% and 22% among recipients with vascular disease at 1 and 2 or more sites, respectively (P<0.001). Compared with recipients without vascular disease, adjusted HRs for mortality and transplant loss were 1.75 (95% CI, 1.39-2.20; P<0.001) and 1.61 (95% CI, 1.30-1.99; P<0.001), respectively, for recipients with 2 or more vascular diseases. Among recipients without diabetes but with 2 or more vascular diseases, adjusted HRs for mortality and transplant loss were 2.10 (95% CI, 1.56-2.82; P<0.001) and 1.84 (95% CI, 1.39-2.42; P<0.001), respectively, compared with those without vascular disease. Similar associations were not observed for recipients with diabetes mellitus (P for interaction < 0.001). LIMITATIONS: Selection bias and unmeasured residual confounders, such as the severity/extent of comorbid conditions likely to be present. CONCLUSIONS: The impact of vascular disease on long-term outcomes was modified by the presence of diabetes, whereby excess risks for death and transplant loss are more apparent in recipients without diabetes. PMID- 29191626 TI - To support and to be supported. A qualitative study of peer support centres in cancer care in Norway. AB - OBJECTIVE: To explore what peer supporters, patients and their relatives want and gain from peer support in cancer care. METHODS: Focus group interviews with peer supporters, and in-depth interviews with peer supporters, patients and relatives (N=38) and observations of daily activities in a Vardesenter ("Cairn Centre"). RESULTS: Peer supporters helped cancer patients and relatives with coping in and outside the hospital in several ways: (1) conveying hope and providing ways to cope in situations where despair would often be prevalent, thus protecting against unhealthy stress; (2) being someone who had the same experiences of disease and treatment, and thus providing a framework for positive social comparisons; and (3) to be an important supplement to family and health care providers. To be working as a peer supporter was also found to be positive and important for the peer supporters themselves. CONCLUSION: The peer support program represented a valuable supplement to informal support from family and friends and healthcare providers, and gave the peer supporters a new role as "professionally unprofessional". PRACTICE IMPLICATIONS: Organised peer support represents a feasible intervention to promote coping for cancer survivors. PMID- 29191627 TI - Scarlet fever makes a comeback. PMID- 29191628 TI - Resurgence of scarlet fever in England, 2014-16: a population-based surveillance study. AB - BACKGROUND: After decades of decreasing scarlet fever incidence, a dramatic increase was seen in England beginning in 2014. Investigations were launched to assess clinical and epidemiological patterns and identify potential causes. METHODS: In this population-based surveillance study, we analysed statutory scarlet fever notifications held by Public Health England from 1911 to 2016 in England and Wales to identify periods of sudden escalation of scarlet fever. Characteristics of cases and outbreaks in England including frequency of complications and hospital admissions were assessed and compared with the pre upsurge period. Isolates from throat swabs were obtained and were emm typed. FINDINGS: Data were retrieved for our analysis between Jan 1, 1911, and Dec 31, 2016. Population rates of scarlet fever increased by a factor of three between 2013 and 2014 from 8.2 to 27.2 per 100 000 (rate ratio [RR] 3.34, 95% CI 3.23 3.45; p<0.0001); further increases were observed in 2015 (30.6 per 100 000) and in 2016 (33.2 per 100 000), which reached the highest number of cases (19 206) and rate of scarlet fever notifcation since 1967. The median age of cases in 2014 was 4 years (IQR 3-7) with an incidence of 186 per 100 000 children under age 10 years. All parts of England saw an increase in incidence, with 620 outbreaks reported in 2016. Hospital admissions for scarlet fever increased by 97% between 2013 and 2016; one in 40 cases were admitted for management of the condition or potential complications. Analysis of strains (n=303) identified a diversity of emm types with emm3 (43%), emm12 (15%), emm1 (11%), and emm4 (9%) being the most common. Longitudinal analysis identified 4-yearly periodicity in population incidence of scarlet fever but of consistently lower magnitude than the current escalation. INTERPRETATION: England is experiencing an unprecedented rise in scarlet fever with the highest incidence for nearly 50 years. Reasons for this escalation are unclear and identifying these remains a public health priority. FUNDING: None. PMID- 29191629 TI - Effects of Delta(9)-tetrahydrocannabinol (THC) on human amniotic epithelial cell proliferation and migration. AB - BACKGROUND: The deleterious effects of cannabis consumption for fertility and pregnancy outcome are recognized for years. The main psychoactive molecule of cannabis, Delta(9)-tetrahydrocannabinol (THC) is able to cross the placenta barrier and cause alterations in fetal growth, low birth weight and preterm labor. However, the effects of THC on the human placenta amnion are still unknown. METHODS: The distributions of CB1R and CB2R in human amnion tissues were observed by immunohistochemistry (IHC). Human amniotic epithelial cell proliferation and migration in response to THC treatment were measured by MTS and transwell assays, respectively. The PCR array was performed to study the key regulators involved in the cell migration. The protein levels of CB1R, CB2R in amnion tissues and MMP2, MMP9 in cells were detected by western blotting. Small interfering RNAs (siRNAs) were used to knockdown MMP2 and MMP9 in WISH cells. RESULTS: Our results indicated that both CB1R and CB2R primarily identified in the epithelial layer of human placental amnion tissue. The CB1R expression in the amnion tissue was higher in the preterm group than normal control. High-dose of THC (30uM, but not 20 and 10uM) significantly inhibited (p<0.01) human amniotic epithelial cell lines (WISH) proliferation. Meanwhile, THC at both 10uM and 20uM (p<0.05) significantly suppressed cells migration in both WISH and primary human amniotic epithelial cells. The PCR array data and siRNA experiments demonstrated that MMP2/9 were tightly involved in the regulation of THC-inhibited cell migration in WISH cells. CONCLUSION: These results suggested that THC inhibited the migration of human amniotic epithelial cell through the regulation of MMP2 and MMP9, which in turn altered the development of the amnion during the gestation and partially resulted in preterm labor and other adverse pregnancy outcomes. PMID- 29191630 TI - Efficacy and safety of bivalirudin in coronary artery disease patients with mild to moderate chronic kidney disease: Meta-analysis. AB - BACKGROUND: Patients with chronic kidney disease (CKD) have elevated bleeding and ischemic outcomes. We aim to assess the short- and long-term efficacy and safety of bivalirudin compared to heparin plus glycoprotein IIb/IIIa inhibitors (GPIs) in coronary artery disease (CAD) patients with CKD. METHODS: Randomized trials were searched in PubMed, Cochrane, and Embase databases up to January 2017. Among the trials retrieved, efficacy endpoints were defined as mortality, myocardial infarction (MI), repeat revascularization, stent thrombosis, and major adverse cardiac events (MACEs). Safety endpoints were reported as non-coronary artery bypass grafting (CABG) related major bleeding and thrombolysis in myocardial infarction (TIMI) major bleeding. Risk ratio (RR) and 95% confidence interval (CI) were calculated for each outcome using a fixed effect model. RESULTS: Five studies with a total of 3796 patients were included. In short-term follow up (30 days), bivalirudin significantly reduced non-CABG related major bleeding (p=0.0004) and TIMI major bleeding (p=0.007) compared to heparin plus GPIs. No significant differences were observed in rates of mortality, MI, repeat revascularization, stent thrombosis, and MACEs between the two groups in short- and long-term follow up (6 months to 3 years). In patients with ST elevated myocardial infarction (STEMI) with concurrent CKD, the decreased non-CABG related major bleeding (p=0.04) without increasing ischemic events was also observed after short-term follow up. CONCLUSIONS: (1) Bivalirudin is safer than and as effective as heparin plus GPIs in CAD patients with CKD. (2) Impaired renal function does not affect the safety benefits of bivalirudin. (3) Similar efficacy profiles were identified between the two groups after both short- and long-term follow up in the CAD patients with CKD. PMID- 29191632 TI - Recent controversy regarding the accuracy of CT-FFR. The truth is out there. PMID- 29191631 TI - [Clinical problems in medical mycology: Problem number 52]. AB - The case of a 60 year old woman with hemoptysis and a thin-walled cavitary lesion at the upper lobe of the right lung is presented. The woman presented at the Mycology Unit of the Muniz Hospital in Buenos Aires City 3 months after the beginning of her clinical manifestations. A hyaline micelial fungus with chlamido arthroconidias was isolated from the bronchoalveolar lavage. Immunodiffusion and counter-immnunoelectrophoresis with coccidioidin and histoplasmin rendered positive results against both antigents, and skin tests with coccidioidin and histoplasmin were also positive with strong reactions. The isolated fungus was identified as Coccidioides posadasii at the National Microbiology Institute Carlos Malbran, by means of a molecular technique. The patient was treated with itraconazole by oral route at a daily dose of 200mg with good clinical response, but due to the persistence of the lung cavity, a surgical removal of the upper lobe of the right lung had to be scheduled. PMID- 29191633 TI - Sensitivity of intervertebral joint forces to center of rotation location and trends along its migration path. AB - Translational vertebral motion during functional tasks manifests itself in dynamic loci for center of rotation (COR). A shift of COR affects moment arms of muscles and ligaments; consequently, muscle and joint forces are altered. Based on posture- and level-specific trends of COR migration revealed by in vivo dynamic radiography during functional activities, it was postulated that the instantaneous COR location for a particular joint is optimized in order to minimize the joint reaction forces. A musculoskeletal multi-body model was employed to investigate the hypotheses that (1) a posterior COR in upright standing and (2) an anterior COR in forward flexed posture leads to optimized lumbar joint loads. Moreover, it was hypothesized that (3) lower lumbar levels benefit from a more superiorly located COR. The COR in the model was varied from its initial position in posterior-anterior and inferior-superior direction up to +/-6 mm in steps of 2 mm. Movement from upright standing to 45 degrees forward bending and backwards was simulated for all configurations. Joint reaction forces were computed at levels L2L3 to L5S1. Results clearly confirmed hypotheses (1) and (2) and provided evidence for the validity of hypothesis (3), hence offering a biomechanical rationale behind the migration paths of CORs observed during functional flexion/extension movement. Average sensitivity of joint force magnitudes to an anterior shift of COR was +6 N/mm in upright and -21 N/mm in 30 degrees forward flexed posture, while sensitivity to a superior shift in upright standing was +7 N/mm and -8N/mm in 30 degrees flexion. The relation between COR loci and joint loading in upright and flexed postures could be mainly attributed to altered muscle moment arms and consequences on muscle exertion. These findings are considered relevant for the interpretation of COR migration data, the development of numerical models, and could have an implication on clinical diagnosis and treatment or the development of spinal implants. PMID- 29191634 TI - A mathematical analysis to address the 6 degree-of-freedom segmental power imbalance. AB - Segmental power is used in human movement analyses to indicate the source and net rate of energy transfer between the rigid bodies of biomechanical models. Segmental power calculations are performed using segment endpoint dynamics (kinetic method). A theoretically equivalent method is to measure the rate of change in a segment's mechanical energy state (kinematic method). However, these two methods have not produced experimentally equivalent results for segments proximal to the foot, with the difference in methods deemed the "power imbalance." In a 6 degree-of-freedom model, segments move independently, resulting in relative segment endpoint displacement and non-equivalent segment endpoint velocities at a joint. In the kinetic method, a segment's distal end translational velocity may be defined either at the anatomical end of the segment or at the location of the joint center (defined here as the proximal end of the adjacent distal segment). Our mathematical derivations revealed the power imbalance between the kinetic method using the anatomical definition and the kinematic method can be explained by power due to relative segment endpoint displacement. In this study, we tested this analytical prediction through experimental gait data from nine healthy subjects walking at a typical speed. The average absolute segmental power imbalance was reduced from 0.023 to 0.046 W/kg using the anatomical definition to <=0.001 W/kg using the joint center definition in the kinetic method (95.56-98.39% reduction). Power due to relative segment endpoint displacement in segmental power analyses is substantial and should be considered in analyzing energetic flow into and between segments.

PMID- 29191635 TI - O-POSSUM score predicts morbidity and mortality in patients undergoing hip fracture surgery. AB - PURPOSE: The aim of this study is to evaluate the O-POSSUM score capacity to predict the morbidity and mortality of patients undergoing hip fracture surgery. MATERIAL AND METHODS: We retrospectively reviewed the clinical records of patients older than 65years old, operated on for hip fractures between January 2012 and December 2013. Of 229 patients, the mean age was 82.3years and 170 were women. We collected comorbidities, type of surgery, and expected morbidity and mortality O-POSSUM values. RESULTS: After a minimum follow up of one year, 38 deaths were reported and 77 patients had complications. The expected mortality according to the O-POSSUM was 35 patients and expected morbidity 132. CONCLUSION: By comparing the observed results with those predicted, the O-POSSUM scale is reliable in predicting mortality and overestimates morbidity. PMID- 29191637 TI - Spontaneous development of hepatosteatosis in perilipin-1 null mice with adipose tissue dysfunction. AB - Fatty liver features triglyceride accumulation in hepatocytes and often occurs with obesity and lipodystrophy in humans. Here, we investigated the mechanism of maladaptive hepatosteatosis with adipose-tissue dysfunction. Perilipin 1 (Plin1) did not exist in hepatocytes but was expressed exclusively in adipocytes as a dual modulator for regulating two principal adipose-tissue functions, triglyceride storage and breakdown. Plin1-/- mice showed decreased fat storage but increased lipolysis and efflux of fatty acids from adipose tissue, and hepatosteatosis spontaneously developed without altered circulating inflammatory adipocytokine levels. Plin1-/- adipose dysfunction impaired insulin sensitivity and hepatic glucose metabolism, which might inhibit gluconeogenesis to produce more intermediates for hepatic lipid synthesis. Indeed, the livers of Plin1-/- mice exhibited upregulated mRNA and protein expression of key enzymes and transcriptional factors for the uptake and transport of fatty acids and for de novo synthesis of triglycerides, but the expression of key enzymes and transcriptional factors for fatty-acid oxidation was downregulated. Biochemical assays in Plin1-/- mice confirmed increased fatty acid synthase activity but decreased activity of mitochondrial carnitine palmitoyltransferase 1 and [3H] palmitate oxidation in the liver. We concluded that dysregulation of two principal functions, adipose storage and hydrolysis, had deleterious consequences on the hepatic lipid metabolism and thereby caused maladaptive hepatosteatosis. This mouse model might mimic and explain the pathogenesis of hepatosteatosis occurring in two typical disorders of adipose tissue dysfunction, obesity and lipodystrophy, particularly in lipodystrophic patients with Plin1 mutation. PMID- 29191639 TI - Population-based Analysis of Treatment Toxicity Among Men With Castration resistant Prostate Cancer: A Phase IV Study. AB - OBJECTIVE: To assess the toxicity and effectiveness of contemporary metastatic castrate-resistant prostate cancer (mCRPC) treatments at a population level, among all patients in Ontario particularly treated with newer agents, including abiraterone, enzalutamide, docetaxel, and cabazitaxel. METHODS: We performed a population-based, retrospective cohort study of 2439 men aged >=65 years treated for mCRPC with abiraterone, enzalutamide, docetaxel, or cabazitaxel from 2003 to 2015 in Ontario, Canada. Our primary outcome was treatment-related toxicity, defined as hospitalizations and emergency room (ER) visits during mCRPC treatment. Based on toxicity profiles identified during phase III trials, we further identified specific treatment-related toxicity. We calculated hazard ratios (HRs) using multivariable Cox proportional hazards models with time varying exposures. RESULTS: Abiraterone and enzalutamide exposure were not associated with any-cause (P = .19 and .52, respectively) or treatment-related (P = .45 and .64, respectively) toxicities. In contrast, docetaxel exposure was associated with an increased risk of any-cause (HR 1.29, 95% confidence interval [CI] 1.15-1.44) and treatment-related (HR 1.52, 95% CI 1.33-1.74) toxicities. Cabazitaxel exposure was associated with a significant risk of treatment-related toxicity (HR 5.94, 95% CI 1.87-18.92) but not any-cause toxicity (HR 2.37, 95% CI 0.59-9.63). CONCLUSION: Among patients with mCRPC, we failed to show any increased risk of hospitalizations and ER visits for treatment-related complications for abiraterone or enzalutamide. In contrast, treatment with intravenous chemotherapeutic agents was associated with an increased risk of hospitalizations and ER visits to manage these complications. PMID- 29191638 TI - Cystathionine gamma-lyase/hydrogen sulfide system is essential for adipogenesis and fat mass accumulation in mice. AB - Hydrogen sulfide (H2S) has been recognized as an important gasotransmitter analogous to nitric oxide and carbon monoxide. Cystathionine gamma-lyase (CSE) derived H2S is implicated in the regulation of insulin resistance and glucose metabolism, but the involvement of CSE/H2S system in energy homeostasis and fat mass has not been extensively explored. In this study, a potential functional role of the CSE/H2S system in in vitro adipocyte differentiation and in vivo adipogenesis and the underlying mechanism was investigated. CSE expression and H2S production were increased during adipocyte differentiation, and that the pattern of CSE mRNA expression was similar to that of CCAAT/enhancer-binding protein (C/EBP) beta and delta, two key regulators for adipogenesis. C/EBPbeta and gamma bind to the CCAAT box in CSE promoter and stimulate CSE gene transcription. H2S induced PPARgamma transactivation activity by S-sulfhydrating all the cysteine residues in the DNA binding domain and stimulated adipogenesis. High fat diet-induced fat mass was lost in CSE deficient mice, and exogenously applied H2S promoted fat mass accumulation in fruit flies. In conclusion, CSE/H2S system is essential for adipogenesis and fat mass accumulation through enhancement of PPARgamma function in adipocytes. This study suggests that the CSE/H2S system is involved in the pathogenesis of obesity in mice. PMID- 29191640 TI - Incidence of Visible Hematuria Among Antithrombotic Agents: A Systematic Review of Over 175,000 Patients. AB - OBJECTIVE: To determine the probability of visible hematuria with antithrombotic agents and to evaluate association of urologic etiology in antithrombotic-related hematuria. METHODS: Preferred Reporting Items in Systematic Reviews and Meta Analyses guidelines were followed to conduct a systematic review using search engines PUBMED and SCOPUS with the terms "(hematuria) OR (haematuria) OR urinary bleeding)) AND ((anticoagulants) OR anticoagulation) OR noac) OR novel anticoagulants) OR antiplatelet) OR dabigatran) OR rivaroxaban) OR apixaban) OR warfarin) OR aspirin) OR heparin) OR dipyridamole)." Raw data were used to perform a pooled analysis. Chi-square and logistic regression analysis were used for statistical analyses. RESULTS: Twenty-two studies describing 175,114 patients met inclusion criteria. Odds ratio of hematuria with warfarin to rivoraxaban was 33 and warfarin to dabigatran was 16. The odds ratio of hematuria for oral anticoagulant (26.7%) to prophylactic parenteral anticoagulant (1.1%) agents was 9.6. Antiplatelet agents are 76 times less likely to cause hematuria compared to anticoagulants. Odds of hematuria with aspirin were 6.7 times the odds with clopidogrel and 3.5 times the odds with ticagrelor. Dabigatran was 198 times more likely to cause major hematuria compared to warfarin, whereas clopidogrel is 1.2 times more likely to cause major hematuria compared to aspirin. Urologic pathology was identified in 44% (234/532) of cases, malignancy in 24%. CONCLUSION: Warfarin use poses the greatest risk for hematuria but is unlikely to cause major hematuria, whereas novel antithrombotic agents are more commonly associated with major hematuria. This review further characterizes the risk profile of antithrombotic agents and associated hematuria to equip clinicians with knowledge to choose an appropriate antithrombotic agent in patients with high-risk hematuria. PMID- 29191641 TI - Vena Cavoscopy in the Assessment of Intraluminal Vena Caval Tumor Involvement. AB - OBJECTIVE: To improve confirmation of complete tumor thrombus removal in advanced malignancy, we report on our experience using intraoperative vena cavoscopy using a flexible cystoscope to confirm complete thrombus resection. Patients with renal cell carcinoma or testicular cancer associated with inferior vena caval tumor involvement benefit from surgical resection of the primary tumor and the tumor thrombus. Intraoperative assessment of the vena cava represents a technical challenge, particularly when the thrombus is friable and involves the hepatic veins, or there is caudal extension of thrombus toward the bifurcation. MATERIAL AND METHODS: From 2006 to 2014, 36 patients underwent tumor thrombectomy and vena cavoscopy. When residual caval thrombus was suspected, a flexible cystoscope was inserted into the vena cava for direct visual inspection of the caval lumen. Perioperative outcomes including residual tumor, changes in management, and postoperative complications were analyzed. RESULTS: All patients underwent endoscopy of the caval lumen without complications. Eight of 36 (22%) patients were found to have residual tumor thrombus visualized during cavoscopy. Five of these patients had evidence of residual mass and caval invasion within the caval lumen that ultimately resulted in cavectomy. Two patients had residual tumor thrombus that was bluntly removed. One patient was found to have significant involvement of the hepatic veins. CONCLUSION: Vena cavoscopy using a flexible cystoscope is a practical technique that may be utilized intraoperatively to ensure clearance of residual thrombus burden within the inferior vena cava and to assess for caval invasion. PMID- 29191642 TI - Combined Partial Penectomy With Bilateral Robotic Inguinal Lymphadenectomy Using Near-infrared Fluorescence Guidance. AB - OBJECTIVE: To describe our novel technique for performing a combined partial penectomy and bilateral robotic inguinal lymphadenectomy using intraoperative near-infrared (NIR) fluorescence guidance with indocyanine green (ICG) and the DaVinci Firefly camera system. METHODS: A 58-year-old man presented status post recent excisional biopsy of a 2-cm lesion on the left coronal aspect of the glans penis. Pathology revealed "invasive squamous cell carcinoma of the penis with multifocal positive margins." His examination was suspicious for cT2 primary and his inguinal nodes were cN0. He was counseled to undergo partial penectomy with possible combined vs staged bilateral robotic inguinal lymphadenectomy. Preoperative computed tomography scan was negative for pathologic lymphadenopathy. Before incision, 5 mL of ICG was injected subcutaneously beneath the tumor. Bilateral thigh pockets were then developed simultaneously and a right, then left robotic modified inguinal lymphadenectomy was performed using NIR fluorescence guidance via the DaVinci Firefly camera. A partial penectomy was then performed in the standard fashion. RESULTS: The combined procedure was performed successfully without complication. Total operative time was 379 minutes and total robotic console time was 95 minutes for the right and 58 minutes to the left. Estimated blood loss on the right and left were 15 and 25 mL, respectively. A total of 24 lymph nodes were retrieved. CONCLUSION: This video demonstrates a safe and feasible approach for combined partial penectomy and bilateral inguinal lymphadenectomy with NIR guidance using ICG and the DaVinci Firefly camera system. The combined robotic approach has minimal morbidity and avoids the need for a staged procedure. Furthermore, use of NIR guidance with ICG during robotic inguinal lymphadenectomy is feasible and may help identify sentinel lymph nodes and improve the quality of dissection. Further studies are needed to confirm the utility of NIR guidance for robotic sentinel lymph node dissection. PMID- 29191643 TI - Incidence of Stress Urinary Incontinence After Posterior Urethroplasty for Radiation-induced Urethral Strictures. AB - OBJECTIVE: To identify the frequency of de novo stress urinary incontinence (SUI) after posterior excision and primary anastomotic (EPA) urethroplasty in patients with radiation-induced urethral strictures (RIUS) and compare with patients with pelvic fracture urethral injuries (PFUIs). MATERIALS AND METHODS: A retrospective review was conducted among patients who underwent successful posterior EPA urethroplasty between 2008 and 2016 for RIUS from prostate cancer or PFUI from blunt trauma. Only patients with an intact bladder neck on imaging were included. SUI was defined by patient-reported outcomes and daily pad use. RESULTS: Inclusion criteria were met by 36 patients with RIUS and 33 patients with PFUI. Among the RIUS cohort, mean follow-up was 18 months, mean stricture length was 2.5 cm, and surgical dissection extended to the prostatic urethra in 67% (n = 24). The overall frequency of de novo SUI among patients with RIUS was 33% (n = 12), of which 75% (9 of 12) had prostatic urethral involvement. Two patients with RIUS (17%, n = 12) proceeded with artificial urinary sphincter (AUS) placement, whereas the remaining 10 patients required pads. SUI after urethroplasty in patients with PFUI was less common (12%, n = 4) and the prostatic urethra was involved in only 3% (n = 1) of all patients with PFUI. One patient with PFUI underwent AUS placement, whereas the remaining 3 patients did not require pads. CONCLUSION: Among RIUS patients with an intact bladder neck, SUI impacts one third of patients. Subsequent AUS placement is uncommon. Prostatic urethral involvement increases risk of SUI. SUI is less common among patients with PFUI, likely related to a more limited involvement of the proximal bulbomembranous urethra and lack of radiation.

AB - AIMS: Previous reports from our laboratory have established that morphine-6-O sulfate (M6S) is a mixed MU/delta opioid receptor (OR) agonist and a potential improved alternative to morphine for treatment of chronic multimodal pain in non diabetic rats. This study extends the antinociceptive effects of M6S and morphine in STZ-induced diabetic rats. MATERIALS AND METHODS: Effects of morphine and M6S were studied across a range of pain modalities, using hot plate threshold (HPT), pinprick sensitivity threshold (PST) and paw pressure threshold (PPT) tests. KEY FINDINGS: Acutely, M6S was 3- to 5-fold more potent and 2- to 3-fold more efficacious than morphine in HPT and PST tests. No differences in analgesic drug potency/efficacy were detected in the PPT test. After 7-9days of chronic treatment, tolerance developed to the antinociceptive effects of morphine, but not to M6S, in all three pain tests. Furthermore, morphine-tolerant rats were not cross-tolerant to M6S. The selective delta-OR antagonist, naltrindole, blocked M6S-induced antinociception by 62+/-3% in the HPT test, 93+/-5% in the PST test, and 30+/-17% in the PPT test when examined acutely. SIGNIFICANCE: These studies provide additional confirmation for the mixed MU/delta activity of M6S and demonstrate potential improved clinical utility for dual MU/delta agonists relative to morphine in treatment of diabetic neuropathy across multiple pain domains.

AB - During their reproductive years women produce significant levels of estrogens, predominantly in the form of estradiol, that are thought to play an important role in cardioprotection. Mechanisms underlying this action include both estrogen mediated changes in gene expression, and post-transcriptional activation of protein signaling cascades in the heart and in neural centers controlling cardiovascular function, in particular, in the brainstem. There, specific neurons, especially those of the bulbar region play an important role in the neuronal control of the cardiovascular system because they control the outflow of sympathetic activity and parasympathetic activity as well as the reception of chemical and mechanical signals. In the present review, we discuss how estrogens exert their cardioprotective effect in part by modulating the actions of internally generated products of cellular oxidation such as reactive oxygen species (ROS) in brain stem neurons. The significance of this review is in integrating the literature of oxidative damage in the brain with the literature of neuroprotection by estrogen in order to better understand both the benefits and limitations of using this hormone to prevent cardiovascular disease. PMID- 29191646 TI - [Thrombotic and haemorrhagic complications in patients with cerebral aneurysms treated by endovascular approach and their association with the use of antiplatelet agents: Descriptive evaluation]. AB - OBJECTIVE: The protocol for optimal antiplatelet therapy to prevent thrombotic complications following brain aneurysm embolisation is not clear. Our objective is to describe the characteristics of patients presenting with thrombotic or haemorrhagic complications secondary to endovascular treatment. METHODS: A cross sectional descriptive study was performed, which included all patients that required endovascular treatment for brain aneurysm at San Ignacio University Hospital from November 2007 to January 2016. Thrombotic and haemorrhagic complications over six months of follow-up were assessed, considering the premedication regimen with antiplatelet agents, location, size of the aneurysm and embolisation technique performed. RESULTS: 122 patients were evaluated, on whom 130 procedures were performed for endovascular treatment of brain aneurysms. Thrombotic complications were more frequent in patients who did not receive premedication (25%) compared to those who did receive an antiplatelet treatment regimen (standard dose 3.87% or loading dose 8.70%), and this difference was statistically significant (P=.043). CONCLUSIONS: Thromboembolic events are the most common complication of brain aneurysm embolisation. Both our study and the literature suggest that the use of dual antiplatelet therapy with aspirin and clopidogrel lowers the rate of symptomatic thromboembolic complications, regardless of the administration protocol. PMID- 29191647 TI - Defining and identifying concepts of medication literacy: An international perspective. AB - BACKGROUND: Multiple concepts to define health literacy in the context of medication use exist, such as medication literacy, pharmacotherapy literacy, pharmacy health literacy; however, no studies have looked at consensus among experts internationally. METHOD: A Delphi process was used to achieve consensus on the statements about medication literacy. Experts for the Delphi were selected from a review of the literature and suggestions from an international survey conducted with members of the International Pharmaceutical Federation on medication literacy. The preliminary Delphi questionnaire was built using the statements about medication literacy found in the scientific literature. Responses and comments were analyzed using a pre-established method and communicated to the experts after each round of Delphi. Statements with an agreement of at least 80% were accepted and used to develop a definition of medication literacy. RESULTS: The Delphi process started with 21 experts and included 4 rounds. Overall, 30 statements regarding medication literacy were accepted and divided into 4 clusters representing: (1) type of information necessary for optimal and safe use of medication, (2) skills and abilities, (3) format of information, and (4) outcomes. These statements were used to propose 2 different definitions of medication literacy. One of the definitions was preferred by 75% of the expert panel, which provided further comments for improvements. Of the 11 experts who answered the final questionnaire, nine strongly agreed with the refined definition. CONCLUSION: Medication literacy is the degree to which individuals can obtain, comprehend, communicate, calculate and process patient-specific information about their medications to make informed medication and health decisions in order to safely and effectively use their medications, regardless of the mode by which the content is delivered (e.g. written, oral and visual). Future studies should focus on how this definition can be operationalized to support the role that pharmacists and other healthcare providers. PMID- 29191648 TI - Ventilation Strategy During Cardiopulmonary Bypass: A Moving Target. PMID- 29191649 TI - Multilevel Thoracic Paravertebral Block Using Ropivacaine With/Without Dexmedetomidine in Video-Assisted Thoracoscopic Surgery. AB - OBJECTIVES: Thoracic paravertebral block (TPVB) is reported to have advantages in postoperative pain management in unilateral thoracic surgeries. Previous studies have demonstrated that dexmedetomidine could be used as an adjuvant to local anesthetics, with the aim of prolonging the duration of neural blockade. However, little is known about whether such a combination could improve the quality of postoperative analgesia compared with local anesthetic only when TPVB is used for patients undergoing video-assisted thoracoscopic surgery (VATS). DESIGN: A prospective, randomized, controlled study. SETTING: Single-center university hospital. PARTICIPANTS: The study included 60 patients undergoing VATS under general anesthesia. INTERVENTIONS: The patients were allocated randomly into the following 2 groups: 0.375% ropivacaine, 20 mL only (group R, n = 30), and 0.375% ropivacaine, 20 mL plus 1 MUg/kg of dexmedetomidine (group RD, n = 30). At the end of surgery, TPVB guided using ultrasound was performed at 4 points-T4-5, T5 6, T6-7, and T7-8-of the surgical side; 5 mL of solution were injected at each point. Postoperatively, the intravenous nonsteroidal anti-inflammatory drug flurbiprofen was used as part of multimodal analgesia. MEASUREMENTS AND MAIN RESULTS: Pain scores at rest and during coughing were evaluated by a blinded observer in the postanesthesia care unit postoperatively at 1, 2, 4, 8, 12, 24, 36, and 48 hours, and the dermatomal levels of sensory blockade, postoperative requirements for rescue analgesia, adverse events, and patient satisfaction also were recorded. There was a significant reduction in postoperative pain scores at rest starting from the postoperative 8th hour until the 48th hour and during coughing starting at the postoperative 4th hour until the 48th hour in the group RD compared with those in group R (p = 0.043). The dermatomal levels of sensory blockade were comparable in the 2 groups. Patient satisfaction after surgery was significantly higher in the group RD than in group R (p < 0.001). Total consumption of the intravenous rescue analgesic morphine and adverse events were not significantly different between the 2 groups. CONCLUSIONS: Compared with ropivacaine only, the addition of dexmedetomidine, 1 MUg/kg, to local anesthetic for multilevel TPVB in patients undergoing VATS prolonged the duration of postoperative analgesia and improved patient satisfaction without serious side effects when combined with postoperative intravenous nonsteroidal anti inflammatory drug administration. PMID- 29191650 TI - Cortical Language Areas and Plasticity in Pediatric Patients With Epilepsy: A Review. AB - Chronic injury to the brain from seizure activity is associated with decreased language skills in pediatric patients, as measured on neuropsychological tests for language function and academic achievement. This makes the study of language in patients with epilepsy clinically necessary. Functional magnetic resonance imaging and direct electrical cortical stimulation have been used to evaluate aspects of cortical language processing in healthy adults and in adults with epilepsy or other neurological insults. Results of these studies help to locate cortical language areas that are involved with modality-specific language processing (visual naming, auditory naming, sentence-completion, and repetition) and the neuroplasticity of language areas in the setting of neurological injury and reorganization. A better understanding of language processing contributes to a more efficient and efficacious electrical cortical stimulation mapping of language areas for patients with intractable epilepsy who are undergoing preresection evaluation. Most of the current literature on localization and reorganization of cortical language areas in the setting of epilepsy concerns the adult patient population, whereas the literature on pediatric patients is substantially lacking in comparison. This article reviews the conclusions drawn thus far from Wada, magnetoencephalography, functional magnetic resonance imaging, and electrical cortical stimulation language studies on types of language reorganization seen in pediatric patients with intractable temporal lobe epilepsy and the clinical factors associated with reorganization, and proposes future directions of research to further the academic and clinical understanding of language processing in pediatric patients. PMID- 29191652 TI - Effect of erythropoietin production induced by hypoxia on autophagy in HepG2 cells. AB - The induction of hypoxia inducible factor (HIF) and autophagy are important cellular responses to hypoxia. The production of erythropoietin (EPO) regulated by HIF is increased by hypoxia and participates in cell protection in various organs and tissues. Signal Transducers and Activator of Transcription 3 (STAT3) is a regulatory factor that is common to autophagy induction and EPO-EPO receptor signaling. In this study, we analyzed the promotion of EPO production and autophagy, and the participation of STAT3, in HepG2 cells under hypoxia. Treatment with EPO siRNA (si-EPO) significantly increased autophagy induction by hypoxia, while treatment with recombinant EPO inhibited the effect of si-EPO. NSC74859, an inhibitor of the phosphorylation of STAT3, increased autophagy induction to the same extent as si-EPO treatment. Even when 3-Methyladenine, an inhibitor of autophagy, was added, the increase of EPO mRNA expression due to hypoxia was not affected. Hypoxia-induced EPO restrained autophagy induction through the EPO receptor and phosphorylation of STAT3. Because cell viability with treatment of si-EPO under hypoxia did not increase over the control, our results suggested that EPO produced by hypoxia prevented excess autophagy induction. PMID- 29191651 TI - Molecular Interactions of a DNA Modifying Enzyme APOBEC3F Catalytic Domain with a Single-Stranded DNA. AB - The single-stranded DNA (ssDNA) cytidine deaminase APOBEC3F (A3F) deaminates cytosine (C) to uracil (U) and is a known restriction factor of HIV-1. Its C terminal catalytic domain (CD2) alone is capable of binding single-stranded nucleic acids and is important for deamination. However, little is known about how the CD2 interacts with ssDNA. Here we report a crystal structure of A3F-CD2 in complex with a 10-nucleotide ssDNA composed of poly-thymine, which reveals a novel positively charged nucleic acid binding site distal to the active center that plays a key role in substrate DNA binding and catalytic activity. Lysine and tyrosine residues within this binding site interact with the ssDNA, and mutating these residues dramatically impairs both ssDNA binding and catalytic activity. This binding site is not conserved in APOBEC3G (A3G), which may explain differences in ssDNA-binding characteristics between A3F-CD2 and A3G-CD2. In addition, we observed an alternative Zn-coordination conformation around the active center. These findings reveal the structural relationships between nucleic acid interactions and catalytic activity of A3F. PMID- 29191653 TI - Distorted antibody repertoire developed in the absence of pre-B cell receptor formation. AB - The pre-B cell receptor (pre-BCR), consisting of the MU heavy chain (MUHC) and the surrogate light chain (SLC, Vpre-B and lambda5), plays important roles during B cell development. The formation of the pre-BCR, which enables the nascent immunoglobulin HC to associate with the SLC, is considered a prerequisite for B cell development. However, a significant number of peripheral mature (leaky) B cells exist in SLC-deficient mice. These leaky B cells develop in the absence of pre-BCR and do not undergo the pre-BCR checkpoint. The antibody repertoires of leaky B cells thus reflect the absence of pre-BCR function. To investigate how the absence of the pre-BCR is circumvented by these leaky-B cells and examine the effect of the pre-BCR checkpoint on the antibody system, we analyzed the antibody repertoires of lambda5-deficient (lambda5-/-) mice using next-generation sequencing. In lambda5-/- mice, spleen B cells displayed different patterns of VDJ-usage, relative to those in wild-type (WT) mice. Moreover, leaky B cells were neither derived from unusual B2 cells, characterized by particular LC gene rearrangements in the absence of pre-BCR signaling, nor from B1 cells, originating from different B cell progenitors. Analysis of the CDR-H3 amino acid sequences of MU-chain repertoires revealed that certain bone marrow B cells with particular CDR-H3 profiles undergo clonal expansion in lambda5-/- mice. Part of these CDR-H3s contain arginine(s) in the middle of the CDR-H3 loop in lambda5-/- mice, whereas few arginine(s) exist in this middle loop in WT CDR-H3s in the absence of clonal expansion. This CDR-H3 feature in lambda5-/- mice presumably reflects the role of the pre-BCR in autoantibody regulation, since arginine(s) are often found in the antigen-binding site of autoantibodies. Here, we present a unique viewpoint on the role of pre-BCR, by assessing the whole antibody repertoire formed in SLC-deficient mice. PMID- 29191654 TI - Differential mGluR5 expression in response to the same stress causes individually adapted hippocampal network activity. AB - Individual differences in stress vulnerability and resilience have been observed even within a single cohort of inbred rats or mice. Stress phenotypes are typically quantified as changes in the behavior of experimental animals, which is the outcome of altered electrical activity of the brain network. Although mGluR5 is associated with individual vulnerability to stress and can act as a sensitive biomarker of stress adaptation, our understanding of mGluR5-dependent modifications to neural network activities in vivo remains limited. Here, we examined individual rats for changes in hippocampal mGluR5 expression induced by restraint stress and found that these changes cause accompanying changes in hippocampal electroencephalography (EEG) activity. We found six days of restraint stress caused variable changes in hippocampal mGluR5 expression, ranging from 20.9% to 210.7% of the control group. The low mGluR5 protein group (LE) showed increased methylation of the mGluR5 CpG island, reduced mGluR5 mRNA levels, and unaltered basal EEG theta spectral power between stress day 1 and 6. In contrast, the high mGluR5 protein group (HE) showed reduced methylation of CpG sites, increased mGluR5 mRNA expression, and reduced basal theta spectral power on stress day 6. We also found that injection of lentiviruses expressing mGluR5 specific shRNAs into the hippocampus rescued this reduction in baseline theta power in HE rats. These data suggest a causal relationship between individual differences in the changes in hippocampal mGluR5 expression induced by repetitive restraint stress and the accompanying changes in ensemble neural activity in the hippocampus. PMID- 29191656 TI - Overexpression of microRNA-26a protects against deficient beta-cell function via targeting phosphatase with tensin homology in mouse models of type 2 diabetes. AB - The prevalence of type 2 diabetes mellitus (T2DM) increased rapidly in the world. The development of beta-cell dysfunction is the quintessential defects in T2DM patients However, the pathogenesis of beta-cell dysfunction is still unclear. MicroRNAs are short non-coding RNAs and has been reported to be involved in pathogenesis of beta-cell dysfunction and T2DM. Here, we investigated the mechanisms by which miR-26a regulate beta-cell function and insulin signaling pathway in high fat diet (HFD) fed and db/db T2DM mice model. The expression of miR-26a was down-regulated dramatically in the serum and islets of both HFD and db/db mice model. miR-26a overexpression protected against HFD-induced diabetes and maintained prolonged normoglycemic time in HFD fed mice. Overexpression of miR-26a improved beta-cell dysfunction in T2DM mice. Further, we identified that PTEN is a direct target gene of miR-26a. Overexpression of miR-26a significantly inhibited the luciferase activity of hPTEN 3'-UTR, while the effect of miR-26a disappeared when the miR-26a potential binding site within the PTEN 3'-UTR was mutated. Overexpression of miR-26a reduced both the mRNA and protein levels of PTEN in vitro and in vivo. We also found that miR-26a overexpression increased the expression of p-Akt and p-FoxO-1, while the effect of miR-26a was blocked by PTEN overexpression. In conclusion, our data indicated that miR-26a potentially contributes to the beta-cell dysfunction in T2DM, and miR-26a may be a new therapeutic strategy against T2DM. PMID- 29191655 TI - Q482H mutation of procaspase-8 in acute myeloid leukemia abolishes caspase-8 mediated apoptosis by impairing procaspase-8 dimerization. AB - INTRODUCTION: Certain procaspase-8 mutations are reported to be associated with the progression and prognosis of multiple tumors. However, it remains unclear whether the poor chemotherapy response and frequent relapse after complete remission of patients with acute myeloid leukemia (AML) is also related to procaspase-8 abnormalities. METHODS: Polymerase chain reaction (PCR) amplification and Sanger sequencing of the procaspase-8 gene (CASP8) were performed. Apoptotic rates were analyzed with Annexin V-FITC staining in cells expressing wild-type (WT) procaspase-8, the Q482H or C360S mutant, or control vector after treatment with or without tumor necrosis factor-related apoptosis inducing ligand (TRAIL). Western blot analysis was performed to detect activation of procaspase-8 and downstream apoptotic signaling pathway components in those cells. The Co-immunoprecipitation (Co-IP) assays were performed to detect interaction between WT and mutant procaspase-8 proteins. RESULTS: AML patients carrying the Q482H mutation were likely to develop chemotherapy resistance. Similar to C360S, The Q482H mutation abolished caspase-8-mediated apoptotic signaling and inhibited TRAIL-induced apoptosis. The Q482H mutation impaired procaspase-8 dimerization, thus preventing the self-activation of procaspase-8. CONCLUSION: The procaspase-8 Q482H mutation in AML patients abolishes caspase-8 mediated apoptosis by impairing procaspase-8 dimerization. PMID- 29191657 TI - Extracellular vesicle-encapsulated microRNA-761 enhances pazopanib resistance in synovial sarcoma. AB - The development of drug resistance in tumor cells leads to relapse and distant metastasis. Secreted microRNAs (miRNAs) enclosed in extracellular vesicles (EVs) can act as intercellular messengers. The objective of our study was to elucidate the role of secreted miRNAs to better understand the regulatory network underlying pazopanib-resistance in synovial sarcoma cells. We performed a comprehensive analysis of secreted miRNA abundance in pazopanib treated/untreated synovial sarcoma cells from four different cell lines (SYO-1, HS-SYII, 1273/99, and YaFuSS) using microarray technology, and discovered miR-761 in EVs as a potential biomarker of pazopanib-resistance in synovial sarcoma. Furthermore, we showed that miR-761 putatively targeted three proteins, thyroid hormone receptor interactor 6 (TRIP6), lamin A/C (LMNA), and NAD-dependent protein deacetylase sirtuin-3 (SIRT3). Knockdown of any of these proteins was shown in previous studies to confer increased resistance to chemotherapeutic agents. Our findings provide new insight into the potential role of miR-761, an EV-secreted miRNA from synovial sarcoma cells, making it a potential candidate for use in sarcoma therapy in the future.

AB - We examined the use of shared medical appointments (SMA) for educating and counseling children with penile problems. Forty-eight families were seen over 4 months with 21 participating in the SMA group and 27 in the traditional group. Using a questionnaire to assess adequacy of education, there was no difference in the overall scores between groups with a mean of 6.64/7 in the SMA and 6.56/7 in the traditional setting. With the increasing demands on providers, an SMA offers a solution to caring for more patients with penile problems in an efficient manner without impacting family education and satisfaction. PMID- 29191658 TI - Identification and target-modifications of temporin-PE: A novel antimicrobial peptide in the defensive skin secretions of the edible frog, Pelophylax kl. esculentus. AB - A potent natural antimicrobial peptide named temporin-PE was identified and encoded from the skin secretions of Pelophylax kl. esculentus via "shotgun" cloning and LC-MS/MS fragmentation analysis. Target-modifications were carried out to further enhance the antimicrobial and anti-proliferative bioactivities, whilst decreasing the hemolytic effect. A range of bioassays demonstrated that replacing a proline with a tyrosine residue resulted in a loss of the bioactivity against Gram-negative bacteria, but dramatically improved the hemolytic and anti proliferative activity, indicating the FLP- motif influences the hemolytic activity of temporins. Moreover, the coupling of TAT to the peptide dramatically improved its antimicrobial activity, indicating coupling TAT to these peptides could be considered as a potential tool to improve their antimicrobial activity. Overall, we have shown that targeted modifications of this natural antimicrobial peptide can adjust its bioactivities to help its development as an antibiotic or anti-proliferative agent. PMID- 29191661 TI - Anterior Segment Dimensions Following Laser Iridotomy in Acute Primary Angle Closure and Fellow Eyes. AB - PURPOSE: To compare the change in anterior segment morphology after laser peripheral iridotomy (LPI) in acute primary angle closure (APAC) and their fellow eyes. DESIGN: Prospective, fellow eye-matched case series. METHODS: In this study 42 individuals with unilateral episode of APAC were enrolled and the anterior segment optical coherence tomography (ASOCT) images were obtained in both eyes at baseline and at 6 weeks after LPI. A linear mixed-effects model was used to compare changes in anterior chamber and angle variables with consideration of laterality as the random effect and pupil diameter as the fixed effect. RESULTS: APAC eyes had smaller angle parameters (P = .013 for all), less central anterior chamber depth (cACD) (P < .001), and lower anterior chamber area (ACA) (P < .001), as well as greater lens vault (LV) (P = .007), compared with fellow eyes. LPI resulted in angle widening with a significant increase in opening distance (P < .01 for all) in both APAC and fellow eyes. cACD (P = .003) and ACA (P < .001) increased and LV (P = .002) decreased in APAC eyes. However, there was no significant change in cACD (P = .190) and LV (P = .430) in fellow eyes. In both APAC eyes and fellow eyes, iris curvature decreased after LPI (P < .001). The changes in angle parameters, ACA, and iris curvature were not significantly different between the 2 groups. CONCLUSION: In APAC eyes and their fellow eyes, LPI resulted in significant anterior chamber angle widening and increased anterior chamber area. In APAC eyes, the iris flattened, cACD deepened, and the lens shifted posteriorly after resolution of the attack. However, in fellow eyes, the increase in ACA was mainly owing to decreased iris curvature. PMID- 29191662 TI - Osseous and Adipocytic Differentiations in the Intraocular Lens and Vitreous. AB - PURPOSE: To analyze 3 unusual mesenchymal transformations within the eye: adipose or osseous metaplasia of the lens and adipose tissue in the vitreous cavity. DESIGN: Observational case series. METHODS: Reevaluation of clinicopathologic diagnoses and histopathologic findings in sections stained with hematoxylin eosin, periodic acid-Schiff (PAS) reaction, and Masson trichrome method. RESULTS: The 3 cases of mesenchymal transformation occurred in microphthalmic eyes with persistent hyperplastic primary vitreous (more recently termed persistent fetal vasculature). In 1 case there was total lens replacement with lamellar bone; in another, total replacement of the crystalline lens by adipose tissue; and in a third, an anomalous pocket of adipose tissue in the central vitreous. Multifocal remnants of the lens capsule were seen in the osseous case but were absent from the adipocytic cases. The vitreous adipose tissue was surrounded by an elaborate capillary plexus with an empty, collapsed PAS-positive lens capsule in the pupillary region. Anterior pigmented neuroectodermal disorganization, dysgenesis of angle structures, and a hypoplastic or disorganized iris were also observed in the 3 cases. CONCLUSIONS: After review of the literature, it appears that lenticular osseous replacement occurs more often than adipocytic. In addition to vascularization of the lens through a capsular dehiscence, other causes are explored, including direct epithelial-mesenchymal transformations of the lens epithelium or, less likely, of the disorganized adjacent neuroectoderm. The focus of vitreous adipose tissue may represent a transformed luxated lens extruded from its capsule, which was left behind in the pupillary zone. PMID- 29191663 TI - Impact of Single-Dose Plerixafor as an Adjunct to Granulocyte Colony-Stimulating Factor-Based Peripheral Blood Stem Cell Mobilization on the Graft Composition and Outcome for T Cell-Replete Haploidentical Peripheral Blood Stem Cell Transplantation with Post-Transplantation Cyclophosphamide: A Comparative Study. AB - We conducted a prospective study on T and natural killer (NK) cell subset composition of graft and transplant outcomes in T cell-replete haploidentical transplantation with a single dose of subcutaneous plerixafor (Px) added to granulocyte colony-stimulating factor (G-CSF)-based mobilization in allogeneic donors to collect 10 * 106/kg CD34+ hematopoietic stem cells (HSCs) at single apheresis. Twnety-six donors received G-CSF + Px and 25 G-CSF alone for mobilization. Despite significantly lower peripheral blood (PB) CD34+ HSCs on day 4 in the G-CSF + Px group (33 [range, 6-47] cells/uL versus 81 [range, 50-168] cells/uL in the G-CSF group; P = .0001), PB CD34+ HSC count (median 136 versus 139 cells/uL) on day 5 as well as that in the graft (2.7 versus 2.3 * 106/mL, P = .1) were comparable between the 2 groups. The total nucleated cell count was higher (3.4 versus 3.1 * 108/mL, P = .05), but CD4+ T cells (2.3 versus 2.7 * 107/mL, P = .09) were lower in the G-CSF group with mobilization of regulatory T cells being similar. NK cells were skewed toward the CD56+/16- subset in both groups, varying significantly from the steady-state NK subset ratio in PB. The time to engraftment, incidences of acute and chronic graft-versus-host disease, nonrelapse mortality, and overall survival were also similar. Addition of single dose Px to G-CSF mobilization improves CD34 recovery and does not significantly alter the T and NK cell composition of the graft, including regulatory T cells, with no adverse impact on transplant outcomes. PMID- 29191664 TI - Immune Reconstitution Following Autologous Stem Cell Transplantation in Patients with High-Risk Neuroblastoma at the Time of Immunotherapy. AB - Outcomes for patients with high-risk neuroblastoma (HR-NBL) are significantly improved with the addition of immunotherapy (dinutuximab + cytokines) following autologous hematopoietic stem cell transplantation (auto-HSCT). We hypothesized that the immune system is not fully reconstituted at the initiation of immunotherapy. To test this hypothesis, we evaluated hematologic and immune subsets in 34 patients with HR-NBL before and after auto-HSCT. We found that absolute T, B, and NK cell counts at the time of immunotherapy were below normal in 80% of patients. Patients with residual disease at the time of transplantation had significantly lower absolute lymphocyte counts (ALC; P = .008), lower CD16+ cell counts (P = .009), and an abnormal ratio of cytokine-releasing to cytotoxic NK cells at the time of dinutuximab treatment. In addition, the preparative regimen used for auto-HSCT predicted immune recovery. Finally, higher total white blood cell count (P = .013) and ALC (P = .013) at 3 months after completion of therapy were measured in patients who remained in remission compared with those who relapsed. Our results indicate that most patients with HR-NBL do not have full immune reconstitution at the time of dinutuximab treatment after auto-HSCT, and that immune recovery may correlate with disease-related outcomes in patients with high-risk disease. PMID- 29191665 TI - Augmenting Total Body Irradiation with a Cranial Boost before Stem Cell Transplantation Protects Against Post-Transplant Central Nervous System Relapse in Acute Lymphoblastic Leukemia. AB - The purpose of this study was to determine the effect of a pretransplant cranial boost (CB) on post-transplant central nervous system (CNS) relapse and survival in acute lymphoblastic leukemia (ALL) patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) using a total body irradiation (TBI)-containing preparation regimen. Two hundred thirteen ALL patients were treated consecutively at our institution with allogeneic HSCT. Conditioning included TBI (1320 cGy in 8 fractions given twice daily) and cyclophosphamide (120 mg/kg) with or without fludarabine (75 mg/m2). Patients were divided into 4 groups based on history of CNS disease and whether a CB was given. Of the 160 patients with no history of CNS disease, none received a CB (CNS-/CB-). Of the 53 patients with prior CNS disease, 41 had not received prior cranial irradiation. Thirty of these 41 received a CB of 900 to 1000 cGy in 5 daily fractions (CNS+/CB+), whereas the other 11 did not receive a CB because of physician preference (CNS+/CB-). The remaining 12 patients with prior CNS involvement had previously received cranial irradiation and thus were not candidates for a CB (CNS + PriorRT). Two-year CNS relapse risk, overall survival (OS), and disease free survival (DFS) were calculated using Kaplan-Meier analysis. Seven patients experienced post-transplant CNS relapse: 4 in the CNS-/CB- group, 2 in the CNS+/CB- group, and 1 in the CNS + PriorRT group. None of the 30 patients who received a CB relapsed in the CNS. Two-year CNS relapse risk was 0% in the CNS+/CB+ group compared with 21% (95% CI, 0% to 45%) in the CNS+/CB- group (P = .03). Two-year OS and DFS did not differ between the groups. In conclusion, among ALL patients with prior CNS leukemia, there was a trend toward a reduced risk of post-transplant CNS relapse in patients who received a CB. However, the addition of a CB did not appear to have an impact on OS or DFS. PMID- 29191666 TI - Nepenthes: State of the art of an inspiring plant for biotechnologists. AB - Plant carnivory results from the adaptation of plants to their environment. The capture and digestion of preys, followed by their assimilation by the plant is a source of additional nutrients to overcome scarce nutrient in poor soils. Nepenthes are highly studied carnivorous plants and have developed a number of ecological traits which have attracted the attention of plant biologists. Multiple adaptive strategies developed by these plants make them a source of inspiration for many applications ranging from therapeutic treatments to biocontrol solution in agriculture. The outstanding tissue organization of the digestive pitcher can help to create new and original materials usable in everyday life. In this review article, we propose a state of the art of the latest studies carried out on these particular plants and we establish a list of potential tracks for their exploitation.

Predictive analysis shows this strain encodes at least 45 gene clusters for the biosynthesis of secondary metabolites, including a type 2 polyketide synthase encoding cluster for the antibacterial formicamycins. Streptomyces formicae KY5 is a new, taxonomically distinct Streptomyces species and this complete genome sequence provides an important marker in the genus of Streptomyces. PMID- 29191668 TI - Non-operative management is feasible for selected blunt trauma patients with pericardial effusion. AB - BACKGROUND: Blunt pericardial effusion (BPE) in trauma patients can be suggestive of injuries to the heart or great vessels. Surgical exploration is the mainstay of management; however, the effectiveness of non-operative management in this patient group remains unclear. METHODS: Patients presenting with BPE in the trauma registry system at our level I trauma center were reviewed. Patients with and without cardiovascular (CVS) injury were compared to identify predictors for CVS injury and to understand the factors related to the requirement for surgery. Patients with and without CVS injury who presented with stable hemodynamics and initially received conservative management were also compared. RESULTS: Thirty patients were enrolled in the study with a mean age of 53.2 (standard deviation (SD) 18.0) years and a mean injury severity score (ISS) of 26.7 (SD 9.0). Eleven patients presented with systolic blood pressure (SBP)<100mmHg, and immediate surgical intervention was performed. Eight patients had evidence of CVS injury (73%). Nineteen patients had stable hemodynamics and initially received conservative treatment. Of these, twelve patients received further surgical interventions, and only three had evidence of CVS injury (16%, 3/19). Comparisons of individuals with and without CVS injury revealed that the SBP on presentation was higher in patients without CVS injury than in those with CVS injury (132.7 (SD 41.3) mmHg vs. 95.6 (SD 21.1) mmHg). Clinically irrelevant differences between the two groups were observed for the creatine kinase (CK)-MB level, the troponin I level, the presence of an echocardiography tamponade sign, associated chest trauma and ISS. No remarkable predictors for CVS injury were found in hemodynamically stable patients. CONCLUSION: Non-operative management can be considered for patents with traumatic BPE and stable hemodynamics; however, this approach must be performed at an institution with adequate facilities and well trained staff. PMID- 29191670 TI - Short-term cooling increases serum angiopoietin-like 4 levels in healthy lean men. AB - BACKGROUND: Cold exposure enhances sympathetic outflow to peripheral tissues, thereby stimulating intracellular lipolysis in white adipose tissue and increasing the lipoprotein lipase-dependent uptake and combustion of triglyceride derived fatty acids (FAs) by brown adipose tissue. Angiopoietin-like 4 (ANGPTL4) inhibits lipoprotein lipase and can be regulated by cold exposure, at least in mice. OBJECTIVE: In the present study, we examined the effect of short-term mild cooling on serum ANGPTL4 levels in healthy lean men of White Caucasian and South Asian descent. METHODS: Healthy, lean White Caucasian (n = 12) and South Asian (n = 12) men were exposed to an individualized cooling protocol for 2 hours. Serum ANGPTL4 levels were measured before and after cooling, and its relation with previously measured parameters (ie, free fatty acid [FFA] levels, body fat percentage, and resting energy expenditure) was determined. RESULTS: Short-term cooling increased ANGPTL4 levels (+17%, P < .001). Thermoneutral ANGPTL4 levels positively correlated with FFA levels (R2 = 0.250, P < .05) and body fat percentage (R2 = 0.338, P < .05). Furthermore, ANGPTL4 negatively correlated with resting energy expenditure (R2 = 0.235, P < .05). The relative increase in ANGPTL4 levels was higher in White Caucasians compared with South Asians (25 +/- 4 vs 9 +/- 4%, P < .05). CONCLUSION: Short-term cooling increases ANGPTL4 levels in healthy lean men. We anticipate that FFA liberated from white adipose tissue during cooling increases ANGPTL4 to limit uptake of triglyceride-derived FA by this tissue. PMID- 29191669 TI - Incidence and factors associated with development of heterotopic ossification after damage control laparotomy. AB - INTRODUCTION: The incidence of heterotopic ossification (HO) following damage control laparotomy (DCL) is unknown. Abdominal wall reconstruction may prove more challenging in patients with HO. This study examines the incidence and factors associated with HO in patients with an open abdomen following DCL. METHODS: A retrospective review of all patients with an open abdomen after DCL at a level 1 trauma centre from 2009 to 2015 was conducted. Demographics and peri-operative outcomes of patients with and without HO were compared. Univariate and multivariable binary logistic regression models were used to determine the association of peri-operative factors with the development of HO. RESULTS: 68 patients were included, of which 36 (53%) developed HO. On univariate analysis, development of HO was significantly associated with hollow viscus injury (OR, 3.89; CI 1.42-10.7), greater number of abdominal surgeries prior to definitive closure (OR, 1.84; CI, 1.10-3.05), non-fascial closure (OR, 4.33; CI, 1.44-13.1) and higher peak ALP (OR 1.01; CI, 1.00-1.02). The presence of a hollow viscus injury remained an independent predictor of HO on multivariable analysis after adjusting for covariates (OR, 3.77; CI, 1.22-11.6). CONCLUSION: Heterotopic ossification develops in a high proportion of trauma patients following damage control laparotomy, particularly in the presence of hollow viscus injury. Its impact on delayed abdominal wall reconstruction and the efficacy of prophylaxis strategies merit further investigation. PMID- 29191671 TI - Erectile Dysfunction and Lower Urinary Tract Symptoms. AB - CONTEXT: Lower urinary tract symptoms (LUTSs) and erectile dysfunction (ED) are substantial health concerns with a significant impact on the overall male quality of life. OBJECTIVE: To evaluate the available evidence of the association between LUTSs and ED in patients with benign prostatic hyperplasia (BPH), and discuss possible clinical implications for the management of LUTS/BPH. EVIDENCE ACQUISITION: A systematic review of the existing literature published between 1997 and June 2017 and available in the Medline, Scopus, and Web of Science databases was conducted using both the Medical Subject Heading (MeSH) and free text protocols. The MeSH search was conducted by combining the following terms: "lower urinary tract symptoms," "LUTS," "benign prostatic hyperplasia," "BPH," "erectile dysfunction," "sexual dysfunction," "BPE," and "benign prostatic enlargement." The Preferred Reporting Items for Systematic Reviews and Meta Analysis guidelines were followed. EVIDENCE SYNTHESIS: Several community-based studies in different geographical areas have provided strong evidence of an age independent association between LUTSs and ED. Several biological mechanisms have been proposed to explain this association, but further research is required to better understand the molecular pathways involved. It is necessary to evaluate the possible impact of the metabolic syndrome treatment on LUTS/ED management. Considering the possible relationship between LUTSs and ED, their impact on the quality of life, and the possible adverse effects associated with LUTS medical treatment, clinicians should always evaluate ED in patients with LUTSs and take the opportunity to evaluate patients reporting ED for LUTSs. CONCLUSIONS: Data from the peer-reviewed literature suggest the existence of an association between LUTS/BPH and ED, although their casual relationship has not been established yet. Emerging data also suggest that pathophysiological mechanisms involved in the metabolic syndrome are key factors in both disorders. Considering the association, it is also recommended that men presenting with LUTSs or ED should be evaluated for both disorders. A better understanding of the molecular pathways behind this association may also help identify new possible targets and develop novel therapeutic approaches to manage LUTSs and ED. PATIENT SUMMARY: In this manuscript, we report on all the available evidence linking erectile dysfunction and lower urinary tract symptoms. Our findings suggest the existence of a strong relationship between these two conditions. On the basis of these findings, we recommend that clinicians always explore both conditions in male patients presenting with either of symptoms.

PMID- 29191673 TI - Automated tracing of helical assemblies from electron cryo-micrographs. AB - Structure determination of helical specimens commonly requires datasets from thousands of micrographs often obtained by automated cryo-EM data acquisition. Interactive tracing of helical assemblies from such a number of micrographs is labor-intense and time-consuming. Here, we introduce an automated tracing tool MicHelixTrace that precisely locates helix traces from micrographs of rigid as well as very flexible helical assemblies with small numbers of false positives. The computer program is fast and has low computational requirements. In addition to helix coordinates required for a subsequent helical reconstruction work-flow, we determine the persistence length of the polymer ensemble. This information provides a useful measure to characterize mechanical properties of helical assemblies and to evaluate the potential for high-resolution structure determination.

AB - BACKGROUND: Laparoscopic common bile duct exploration is an underutilized treatment for choledocholithiasis. We sought to evaluate the impact of a simulation-based mastery-learning curriculum for surgical residents on laparoscopic common bile duct exploration utilization and to compare outcomes for patients treated with laparoscopic common bile duct exploration versus endoscopic retrograde cholangiopancreatography (ERCP). METHODS: The number of laparoscopic common bile duct explorations performed before and after curriculum implementation was reviewed and outcomes were compared between patients with choledocholithiasis managed with laparoscopic common bile duct exploration and endoscopic retrograde cholangiopancreatography. Based on cost savings from increased utilization of laparoscopic common bile duct exploration, the annual return on investment associated with the curriculum was calculated. RESULTS: Twenty-two residents completed the curriculum. In the pre-curriculum period, an average of 1.7 laparoscopic common bile duct explorations was performed yearly, which increased to 8.4 cases per year after curriculum implementation (P < .05). Identified were 155 patients with choledocholithiasis: 31 underwent laparoscopic common bile duct exploration plus laparoscopic cholecystectomy and 124 underwent endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy. The laparoscopic common bile duct exploration and laparoscopic cholecystectomy group had a reduced duration of stay (2.5 +/- 1.8 days versus 4.3 +/- 2.2 days, P < .0001) and costs ($12,987 +/- $3,286 versus $15,022 +/- $4,613, P = .01) compared with endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy. Rates of readmission and reoperation were equivalent between groups. Cost savings were more than $38,000, resulting in a 3.8 to 1 return on investment from curriculum implementation. CONCLUSION: A simulation-based mastery learning curriculum increased institutional utilization of laparoscopic common bile duct exploration and adoption of the curriculum resulted in positive return on investment. PMID- 29191676 TI - Does anatomic resection improve the postoperative outcomes of solitary hepatocellular carcinomas located on the liver surface? AB - BACKGROUND: It is unclear whether anatomic resection achieves better outcomes than nonanatomic resection in patients with hepatocellular carcinoma. This study aimed to compare the outcomes of anatomic resection and nonanatomic resection for hepatocellular carcinoma located on the liver surface via one-to-one propensity score-matching analysis. METHODS: Data from all consecutive patients who underwent liver resection for primary solitary hepatocellular carcinoma at Nara Medical University Hospital, Japan, January 2007- December 2015 were retrieved. Superficial hepatocellular carcinomas were defined as hepatocellular carcinoma that extended to a depth of < 3 cm from the liver surface and measured < 5 cm in diameter. The prognoses of the patients with superficial hepatocellular carcinoma who underwent anatomic resection and nonanatomic resection were compared. RESULTS: In this study 23 patients with superficial hepatocellular carcinoma underwent anatomic resection and 70 patients who underwent nonanatomic resection. The recurrence-free survival rate of the patients who underwent anatomic resection was better than that of the patients who underwent nonanatomic resection (P = .006), while no such difference was observed for nonsuperficial hepatocellular carcinoma. After the propensity score-matching procedure, the resected liver volume and operation time were the only background or clinical characteristics to exhibit significant differences between the anatomic resection (n = 20) and nonanatomic resection groups (n = 20). The recurrence-free survivial rate of the patients who underwent anatomic resection was significantly than that of the patients that underwent nonanatomic resections (P = .030), but overall survival did not differ significantly between the groups (P = .182). CONCLUSION: Anatomic resection decreases the risk of tumor recurrence and improves recurrence free survival compared with nonanatomic resection in patients with superficial hepatocellular carcinoma. PMID- 29191677 TI - Inhibition of Toll-like receptor 4 ameliorates experimental postischemic injury in the cholestatic liver through inhibition of high-mobility group box protein b1 (HMGB1) signaling. AB - BACKGROUND: The objective of this study was to elucidate whether the inhibition of Toll-like receptor 4 attenuates liver injury ischemia/reperfusion in the cholestatic liver. METHOD: Rats were assigned into sham, bile duct ligation, sham ischemia/reperfusion (ischemia/reperfusion after laparotomy), and bile duct ligation ischemia/reperfusion (ischemia/reperfusion after bile duct ligation) groups. In some rats, TAK-242, an inhibitor of Toll-like receptor 4, was administered 15 minutes before ischemia/reperfusion. We measured intrahepatic Toll-like receptor 4 expression, serum hepatic marker expression, liver necrosis, gene expression of inflammation-associated factors, and serum high-mobility group box protein b1 levels. RESULTS: Intrahepatic Toll-like receptor 4 expression was significantly greater in the bile duct ligation group than in the sham group. Toll-like receptor 4 expression was further increased after ischemia/reperfusion in bile duct ligation ischemia/reperfusion groups. The levels of serum hepatic markers were significantly greater in both the sham ischemia/reperfusion and bile duct ligation ischemia/reperfusion groups than in the groups without ischemia/reperfusion. Liver necrosis was greater in the bile duct ligation group than in the sham group and was further increased in the bile duct ligation ischemia/reperfusion group. Genomic expression of inflammation-associated factors was also significantly greater in the bile duct ligation ischemia/reperfusion group than in the sham group. Serum high-mobility groups box protein b1 levels were greater in the bile duct ligation ischemia/reperfusion group than in the sham group (28.1 ng/ml versus 9.2 ng/ml, P = .011) and the bile duct ligation group (28.1 ng/ml versus 10.6 ng/ml, P = .017). These changes in the bile duct ligation ischemia/reperfusion group were significantly attenuated by preconditioning with TAK242. CONCLUSIONS: Toll-like receptor 4 inhibition has a potential to minimize severe injury after ischemia/reperfusion in the cholestatic liver through inhibition of high-mobility groups box protein b1. PMID- 29191678 TI - Comparison of digital color fundus imaging and fluorescein angiographic findings for the early detection of diabetic retinopathy in young type 1 diabetic patients. AB - PURPOSE: To compare the findings from digital 7-field color fundus (CF) photography and fundus fluorescein angiography (FFA) in young patients with diabetes mellitus (DM) type 1 without known diabetic retinopathy. METHODS: In this prospective, observational cohort study, 54 type 1 diabetic patients were recruited. Participants had been diagnosed with diabetes mellitus (DM) for at least 6 years, had Best Corrected Visual Acuity of 20/25 or better and did not have any known retinal pathology. One hundred and seven eyes were analyzed. All patients underwent a complete ophthalmic examination in the Retina Service of a University Eye Clinic including digital CF imaging and FFA. RESULTS: The mean age of the patients was 18.6 years. Mean duration of DM was 11.3 years, and mean haemoglobin A1c (HbA1c) level was 8.6%. Of the 107 eyes, 8 eyes (7.5%) showed microvascular abnormalities on CF images, while FFA images revealed changes in 26 eyes (24.3%). Hence, 18 of the 26 eyes showing abnormalities on FFA did not show any abnormalities on CF images. Mean DM duration in the patient group with detectable microvascular changes was found to be significantly higher compared to patients without changes, while no difference in HbA1c levels, serum lipid levels or blood pressure was observed. CONCLUSIONS: Comparison of digital CF and FFA findings for the detection of diabetic microvascular changes in type 1 diabetic patients showed that FFA reveals more information about retinal vascular pathology for early detection of diabetic retinopathy. PMID- 29191680 TI - Food allergy: Update on prevention and tolerance. AB - Of the many possible hypotheses that explain the recent increase in childhood food allergy (FA), the dual-allergen exposure hypothesis has been the most extensively investigated. This chapter serves as a review and update on the prevention of FA and focuses on recently published randomized controlled trials exploring the efficacy of oral tolerance induction in infancy for the prevention of FA. As a result of these RCTs, National Institutes of Health recommendations now actively encourage the early introduction of peanut for the prevention of peanut allergy, and other countries/settings recommend the inclusion of potential common food allergens, including peanut and egg, in complementary feeding regimens commencing at approximately 6 months but not before 4 months of age. Further studies that explore the efficacy of oral tolerance induction to other common food allergens and that focus on optimal timing, duration, and adherence are required. PMID- 29191679 TI - Intraocular pressure measurements and corneal biomechanical properties using a dynamic Scheimpflug analyzer, after several keratoplasty techniques, versus normal eyes. AB - PURPOSE: To evaluate the biomechanical properties of the cornea and their impact on intraocular pressure (IOP) measurement after lamellar keratoplasty, compared to healthy eyes, using a non-contact tonometer with a Scheimpflug camera. METHODS: This study, from 2014 to 2015, included 22 primary DSAEK, 5 DALK, 6 DSAEK after PK, and 50 control eyes. Using a non-contact tonometer with a high speed Scheimpflug camera (CORVIS ST, Oculus Optikgerate GmbH, Wetzlar, Germany), several biomechanical parameters were recorded, including radius at highest concavity (Rhc) and defomation amplitude (DA). Central corneal thickness (CCT) and uncorrected IOP, were also recorded. For the control eyes only, a corrected IOP was calculated, based on age, central corneal thickness, and biomechanical parameters. RESULTS: Rhc was significantly lower after DALK (Rhc=5.54+/-0.71, P=0.007) and DSAEK (Rhc=6.26+/-0.77, P=0.042) compared to control eyes (Rhc=6.82+/-0.76). DA was higher after DALK and DSAEK, but not significantly (respectively 1.24+/-0.09 P=0.41 and 1.22+/-0.15, P=0.923) compared to normal eyes (1.18+/-0.15). Uncorrected IOP was not significantly different between post keratoplasty and control eyes. In control eyes, the corrected IOP (15.23+/-1.88) was lower than the uncorrected IOP (16.10+/-2.34); a statistically significant positive correlation between Rhc and CCT (R2=0.6020, P<0001), and a significant negative correlation between DA and CCT (R2=-0.641, P<0.0001) were found. CONCLUSION: Our study showed that, after lamellar keratoplasty, corneal biomechanics are altered. Corneas with higher ocular rigidity will show a lower DA and a higher Rhc. PMID- 29191681 TI - Social behavior-induced multistability in minimal competitive ecosystems. AB - Mimimal models of coordinated behavior of populations living in the same environment are introduced for the cases when they either both gain by mutual interactions, or one hunts the other one, or finally when they compete with each other. The equilibria of the systems are analysed, showing that in some cases the populations may both disappear. Coexistence leads to global asymptotic stability for symbiotic populations, or to Hopf bifurcations for predator-prey systems. Finally, a new very interesting phenomenon is discovered in the competition case: tristability may be achieved showing that the principle of competitive exclusion fails in this case. Indeed either one of the competing populations may thrive, but also the case of populations coexistence is allowed, for the same set of parameter values. PMID- 29191682 TI - Complete mitochondrial genome of Saturnia jonasii (Lepidoptera: Saturniidae): Genomic comparisons and phylogenetic inference among Bombycoidea. AB - The complete mitochondrial genome (mitogenome) of Saturnia jonasii (Lepidoptera: Saturniidae) was sequenced and compared to those of 19 other bombycoid species. Furthermore, the mitogenome sequences were used to infer phylogenetic relationships among bombycoid species. The 15,261-bp Saturnia jonasii mitogenome contained the typical sets of genes and gene arrangements found in majority of Lepidoptera. All Bombycoidea species, including Saturnia jonasii, have a 15-33-bp spacer sequence at the trnS2-ND1 junction. The phylogenetic reconstruction of bombycoid species consistently and strongly supported monophylies of the families, Saturniidae, Bombycidae, and Sphingidae, based on Bayesian inference (BI) and maximum-likelihood (ML) methods. Among these families, the Bombycidae and Sphingidae species consistently showed a sister relationship, regardless of data partitions; the BI method strongly supported this relationship, whereas it was moderately supported using the ML method. PMID- 29191683 TI - Clinical outcome after 36 months of treatment with injections of autologous blood for recurrent dislocation of the temporomandibular joint. AB - We investigated the prognosis after three years of treatment for recurrent dislocation of the temporomandibular joint with autologous blood given intravenously in 21 patients with a mean (range) age 64 (17-92) years of whom 16 had coexisting systemic disease. The mean (range) follow up from the first injection was 64 (41-99) months. Eighteen patients had no recurrence during the first 36 months after their first injection, which showed that this minimally invasive treatment was effective, particularly for those who had conditions that made a mouthpiece or operation unsuitable. PMID- 29191685 TI - Breast MRI as a Problem-solving Study in the Evaluation of BI-RADS Categories 3 and 4 Microcalcifications: Is it Worth Performing? AB - RATIONALE AND OBJECTIVES: We aimed to investigate the utility of problem-solving breast magnetic resonance imaging (MRI) for mammographic Breast Imaging Reporting and Data System (BI-RADS) categories 3 and 4 microcalcifications. MATERIALS AND METHODS: Between January 1, 2010 and December 31, 2011, 138 women with 146 areas of categories 3 and 4 microcalcifications without sonographic correlates underwent breast MRI and had a stereotactic core biopsy using an 11-gauge needle or follow-up at least for 24 months. Positive predictive value (PPV), negative predictive value, sensitivity, and specificity were calculated on the basis of BI RADS category, with categories 1-3 being considered benign and categories 4 and 5 being considered malignant. RESULTS: Twenty-four cases (16.4%) were malignant (18 ductal carcinoma in situ, 6 invasive). MRI increased PPV and specificity from 43% to 68% and from 80% to 93% (P = .054 and .005) compared to mammography. Within 102 category 3 microcalcifications, 5 carcinomas were assessed correctly as category 4 by MRI. Within 44 category 4 microcalcifications, a correct diagnosis was made by MRI in 77% (34 of 44) as opposed to 43% (19 of 44) by mammography, and 80% (20 of 25) of unnecessary biopsies could have been avoided. Within the 24 carcinomas, 5 were negative at MRI. MRI-negative carcinomas have a significantly higher possibility of being low grade (ductal carcinoma in situ or invasive) (P = .0362). CONCLUSIONS: Breast MRI has the potential to improve the diagnosis of category 3 or 4 microcalcifications and could alter indications for biopsy. Breast MRI could help predict the presence or absence of higher-grade carcinoma for category 3 or 4 microcalcifications. PMID- 29191684 TI - Model-based Iterative Reconstruction in Low-radiation-dose Computed Tomography Colonography: Preoperative Assessment in Patients with Colorectal Cancer. AB - RATIONALE AND OBJECTIVES: To assess the effect of model-based iterative reconstruction (MBIR) on image quality and diagnostic performance of low radiation-dose computed tomography colonography (CTC) in the preoperative assessment of colorectal cancer. MATERIALS AND METHODS: This study included 30 patients with colorectal cancer referred for surgical treatment. All patients underwent CTC with a standard dose (SD) protocol in the supine position and a low dose (LD; radiation dose reduction of approximately 85%) protocol in the prone position. The SD protocol images were post-processed using filtered back projection (FBP), whereas the LD protocol images were post-processed using FBP and MBIR. Objective and subjective image quality parameters were compared among the three different methods. Preoperative evaluations, including site, length, and tumor and node staging were performed, and the findings were compared to the postsurgical findings. RESULTS: The mean image noise of SD-FBP, LD-FBP, and LD MBIR images was 17.3 +/- 3.2, 40.5 +/- 10.9, and 11.2 +/- 2.0 Hounsfield units, respectively. There were significant differences for all comparison combinations among the three methods (P < .01). For image noise, the mean visual scores were significantly higher for SD-FBP and LD-MBIR than for LD-FBP, and the scores for SD-FBP and LD-MBIR were equivalent (3.9 +/- 0.3 [SD-FBP], 2.0 +/- 0.5 [LD-FBP], and 3.7 +/- 0.3 [LD-MBIR]). Preoperative information was more accurate under SD FBP and LD-MBIR than under LD-FBP, and the information was comparable between SD FBP and LD-MBIR. CONCLUSION: MBIR can yield significantly improved image quality on low-radiation-dose CTC and provide preoperative information equivalent to that of standard-radiation-dose protocol. PMID- 29191686 TI - CT Features of Hepatic Veno-occlusive Disease: A Meta-analysis. AB - RATIONALE AND OBJECTIVE: The computed tomography (CT) features of hepatic veno occlusive disease (HVOD) could play a role in its diagnosis. We aimed to perform a meta-analysis of studies examining the CT features of HVOD. METHODS: Relevant studies published up to May 3, 2017 were searched in major electronic databases. The extracted data included the proportion of various CT features in patients with HVOD. The meta-analysis was conducted using R 3.3.3 with the "meta" package. RESULTS: Eleven studies were included. The studies involved 326 patients with a mean age range of 50.2-58.9 years, and the proportion of female patients ranged from 20% to 57.5%. The meta-analysis showed the pooled proportion of CT features: hepatic parenchyma with heterogeneous hypoattenuation (81.05%, 95% confidence interval [CI]: 56.97%-93.25%), patchy enhancement in the portal venous phase (87.09%, 95% CI: 75.15%-93.77%) with or without a narrow or invisible hepatic vein (71.02% 95% CI: 42.09%-89.20%), gallbladder wall edema (65.51%, 95% CI: 28.98%-89.84%), and patchy heterogeneous enhancement in the arterial phase (44.36%, 95% CI: 29.98%-59.76%) with or without slightly enlarged hepatic artery (56.61%, 95% CI: 40.62%-71.33%). CONCLUSION: Hepatic parenchyma with heterogeneous hypoattenuation and patchy enhancement with or without narrowing or an invisible hepatic vein in the portal venous or equilibrium phase may be the most important CT feature for diagnosing HVOD. PMID- 29191687 TI - Interpreting Change in Quantitative Imaging Biomarkers. AB - RATIONALE AND OBJECTIVES: Quantitative imaging biomarkers (QIBs) are becoming increasingly adopted into clinical practice to monitor changes in patients' conditions. The repeatability coefficient (RC) is the clinical cut-point used to discern between changes in a biomarker's measurements due to measurement error and changes that exceed measurement error, thus indicating real change in the patient. Imaging biomarkers have characteristics that make them difficult for estimating the repeatability coefficient, including nonconstant error, non Gaussian distributions, and measurement error that must be estimated from small studies. METHODS: We conducted a Monte Carlo simulation study to investigate how well three statistical methods for estimating the repeatability coefficient perform under five settings common for QIBs. RESULTS: When the measurement error is constant and replicates are normally distributed, all of the statistical methods perform well. When the measurement error is proportional to the true value, approaches that use the log transformation or coefficient of variation perform similarly. For other common settings, none of the methods for estimating the repeatability coefficient perform adequately. CONCLUSION: Many of the common approaches to estimating the repeatability coefficient perform well for only limited scenarios. The optimal approach depends strongly on the pattern of the within-subject variability; thus, a precision profile is critical in evaluating the technical performance of QIBs. Asymmetric bounds for detecting regression vs progression can be implemented and should be used when clinically appropriate. PMID- 29191688 TI - Diaphragm and lung-preserving surgery with hyperthermic chemotherapy for malignant pleural mesothelioma: A 10-year experience. AB - BACKGROUND: The best surgical treatment for malignant pleural mesothelioma is still under a debate, but recent evidence points toward a less-invasive approach to reduce morbidity and mortality. We reported our 10-year experience of a limited surgical approach associated with hyperthermic intrathoracic chemotherapy (HITHOC). MATERIAL AND METHODS: Between 2005 and 2014, patients with epithelioid or biphasic malignant pleural mesothelioma were treated with lung-diaphragm pericardium-sparing pleurectomy associated with double-drug HITHOC; at least 3 cycles of adjuvant chemotherapy were then administered. The primary outcome examined was the feasibility of the procedure, whereas secondary outcomes were overall survival and disease-free interval. RESULTS: Among 49 patients, 41 were male. Median age was 68 years (35-76 years). Histology was epithelioid in 43 cases. Pathologic stage I, II, III, and IV occurred in 12, 14, 20, and 3 cases, respectively. No intraoperative complications or postoperative mortality occurred, whereas morbidity rate was 46.9%. Median hospital stay was 8 days (5-45 days). Actuarial median overall survival was 22 months and a 1-, 2-, and 5-year survival accounted for 79.6%, 45.7%, and 9.9%, respectively. Disease-free survival after surgery was 62%, 37.5%, and 18.5% at 1, 2, and 5 years, respectively. Risk factors analysis for overall survival confirmed a significant role for early stages, epithelioid histology, and fibrinogen serum levels. CONCLUSIONS: Cytoreductive surgery associated with HITHOC and adjuvant chemotherapy appears feasible and safe, with no mortality and low morbidity. Preserving lung and diaphragmatic function might warrant an acceptable long-term outcome. PMID- 29191689 TI - Does the surgical waiting list affect pathological and survival outcome in resectable pancreatic ductal adenocarcinoma? AB - BACKGROUND: High-volume centers have to deal with long surgical waiting-lists leading to a potential delay in treatment. This study assessed whether a longer time from diagnosis to surgery worsened pathological and survival outcomes in resectable pancreatic ductal adenocarcinoma (PDAC). METHODS: A retrospective analysis of patients treated for resectable PDAC. Difference in size between preoperative CT-scan and specimen, pathological features, the rate of vascular and R1 resections as well as recurrence and survival were analyzed depending on the waiting time using a 30-day cut-off. RESULTS: Waiting more than 30 days for surgery was associated with an increase in tumor size on specimen when compared with CT-scan (+3 vs. +1 mm, p = 0.04). T and N status, rate of vascular resection, grading, perineural and lymphovascular infiltration, and R1 rates did not differ between groups, as well as tumor recurrence (48.8% vs. 48.9%, p = 0.5) and survival (31 vs. 29 months, p = 0.7). For PDAC < 20 mm, waiting less than 30 days improved overall survival (p = 0.02). CONCLUSION: The duration of the surgical waiting-list did not affect pathological features and survival. Delayed surgery was associated with increased cancer size on the specimen. However, surgery should not be delayed for PDACs < 20 mm as this may negatively affect the prognosis. PMID- 29191690 TI - The extent of vascular resection is associated with perioperative outcome in patients undergoing pancreaticoduodenectomy. AB - BACKGROUND: Few studies have examined the relation between extent of vascular resection and morbidity following pancreaticoduodenectomy (PD) with vein resection (PDVR). METHODS: Patients undergoing PD for malignancy were identified using the American College of Surgeons National Surgical Quality Improvement Project from 2006 to 2013. Current procedural terminology codes were used to characterize PDVR. RESULTS: 9235 patients underwent PD, 977 (10.6%) had PDVR - 640 with direct and 224 with graft repair. PDVR had longer operative times (456 +/- 136 vs 374 +/- 128 min, p < 0.05) and higher intraoperative transfusions (1.8 +/- 3.4 vs 4.3 +/- 4.9 units, p < 0.05) than PD alone. On adjusted multivariable regression, PDVR with either direct or graft repairs was associated with higher rates of overall morbidity (OR [odds ratio] 1.50 for direct, 1.74 for graft, p < 0.05), bleeding (OR 2.18 for direct, 3.26 for graft, p < 0.05), and DVT (OR 2.12 for direct, 2.62 for graft, p < 0.05) compared to PD alone. Graft repair was further associated with increased risk of reoperation (OR 1.59), septic shock (OR 2.77) and 30-day mortality (OR 2.72), all p < 0.05. DISCUSSION: The risk of significant morbidity and mortality for PDVR is associated with the extent of vascular resection, with graft repairs having increased morbidity and mortality rates. PMID- 29191691 TI - Assessing the impact of conversion on outcomes of minimally invasive distal pancreatectomy and pancreatoduodenectomy. AB - BACKGROUND: Our aim was to compare outcomes of patients who undergo conversion to open during minimally invasive distal pancreatectomy (MI-DP) and pancreatoduodenectomy (MI-PD) to those completed in minimally invasive fashion, and to compare outcomes of minimally invasive completions and conversions to planned open pancreatectomy. METHODS: Propensity scoring was used to compare outcomes of completed and converted cases from a national cohort, and multivariate regression analysis (MVA) was used to compare minimally invasive completions and conversions to planned open pancreatectomy. RESULTS: MI-DP was performed in 43.0%. Conversions (20.2%) had increased morbidity (32.3 vs 42.0%), serious morbidity (11.1 vs 21.2%), and organ space infection (6.2 vs 14.2%). Outcomes of MI-DP conversions were comparable to open. MI-PD was performed in 6.1%. Conversions (25.2%) had increased organ space infection (10.9 vs 26.6%), blood transfusions (17.2 vs 42.2%), and clinically relevant pancreatic fistula (11.5 vs 28.1%). On MVA, conversion of MI-PD was associated with increased mortality (OR 2.84, 95% CI 1.09-7.42), post-operative percutaneous drain placement (OR 2.36, 95% CI 1.32-4.20), and blood transfusions (OR 1.85, 95% CI 1.07-3.21). CONCLUSION: Converted cases have increased morbidity compared to completions, and for patients undergoing PD, conversions may be associated with inferior outcomes compared to planned open cases. PMID- 29191692 TI - Thermodynamic properties of an emerging chemical disinfectant, peracetic acid. AB - Peracetic acid (PAA or CH3COOOH) is an emerging disinfectant with a low potential to form carcinogenic disinfection by-products (DBPs). Basic thermodynamic properties of PAA are, however, absent or inconsistently reported in the literature. This review aimed to summarize important thermodynamic properties of PAA, including standard Gibbs energy of formation and oxidation-reduction (redox) potential. The standard Gibbs energies of formation of CH3COOOH(aq), CH3COOOH(g), CH3COOOH(l), and CH3COOO(aq)- are -299.41kJ.mol-1, -283.02kJ.mol-1, -276.10kJ.mol 1, and -252.60kJ.mol-1, respectively. The standard redox potentials of PAA are 1.748V and 1.005V vs. standard hydrogen electrode (SHE) at pH 0 and pH 14, respectively. Under biochemical standard state conditions (pH 7, 25 degrees C, 101,325Pa), PAA has a redox potential of 1.385V vs. SHE, higher than many disinfectants. Finally, the environmental implications of the thermodynamic properties of PAA were systematically discussed. Those properties can be used to predict the physicochemical and biological behavior of aquatic systems exposed to PAA. PMID- 29191693 TI - Association between rs823128 polymorphism and the risk of Parkinson's disease: A meta-analysis. AB - Numerous published case-control studies have investigated a role of PARK16 gene in susceptibility to Parkinson's disease (PD), but the results remain conflicting and under-powered. Herein, we performed this meta-analysis to evaluate the possible association between the polymorphism of the PARK16 rs8231128 (A/G) and PD.A comprehensive search of six databases was conducted to identify all case control studies involving PARK16rs823128variants and PD risk up to August 2017. The strict inclusion and exclusion criteria were applied. A total of 9 studies including 15 case-control studies with 7277 PD cases and 6188 controls were included in the meta-analysis. And STATA 12.0 statistics software was used to calculate available data from each study. The crude odds ratios (OR) and 95% confidence interval (CI) were calculated to assess the genetic association between PARK16 rs823128 polymorphism and the risk of PD. In the combined analysis, results showed a significant association between rs823128 and PD in allelic model(G vs. A: OR=0.886, 95% CI=0.811-0.969, P=0.008), dominant model (GG+ AG vs. AA: OR=0.886, 95% CI=0.804-0.976, P=0.014), and heterozygote model (AG vs. AA: OR=0.897, 95% CI=0.812-0.991, P=0.032). Further, ethnicity based analysis showed a significant association in Asian and Chilean population, but not in Caucasian samples. Within its limitations, this meta-analysis demonstrated that the rs823128 variants(G allele, GA and GG genotype)in PARK16 might be a potential protective factor for PD. However, these associations vary in different ethnicities. PMID- 29191694 TI - Frontal evoked gamma activity modulates behavioural performance in Autism Spectrum Disorders in a perceptual simultaneity task. AB - Autism spectrum disorders (ASDs) are associated with anomalies in time perception. In a perceptual simultaneity task, individuals with ASD demonstrate superior performance compared to typically developing (TD) controls. gamma activity, a robust marker of visual processing, is reportedly altered in ASD in response to a wide variety of tasks and these differences may be related to superior performance in perceptual simultaneity. Using time-frequency analysis, we assessed evoked gamma-band phase-locking in magnetoencephalographic recordings of 16 ASD individuals and 17 age-matched TD controls. Individuals judged whether presented visual stimuli were simultaneous or asynchronous. We identified left frontal gamma-activity in ASD, which was associated with a reduced perception of simultaneity. Where feature binding was observed at a neurophysiological level in parieto-occipital cortices in ASD in apparent simultaneity (asynchronous stimuli with short delay between them), this did not predict the correct behavioural outcome. These findings suggest distinct gamma profiles in ASD associated with the perception of simultaneity. PMID- 29191695 TI - Association of circulating manganese levels with Parkinson's disease: A meta analysis. AB - Whether systemic manganese (Mn) dysfunctions in Parkinson's Disease (PD) is still under ongoing debate. The recent reported studies on the circulating Mn levels in PD showed inconsistent results. A meta-analysis study was conducted to evaluate the association of circulating Mn levels with PD, and to clarify whether Mn should be considered as a potential risk factor for PD. A systematic searching was performed based on PubMed, web of science, and China National Knowledge Infrastructure (CNKI). Finally, 22 studies were identified, involving 637 PD patients and 802 health controls (HC) individuals for serum Mn, 1258 PD patients and 1304 HC individuals for peripheral blood Mn, and 195 PD patients and 196 HC individuals for cerebrospinal fluid (CSF) Mn. Forest plots were adopted to represent the comparison of the groups by assessing standardized mean difference with random effects model. This meta-analysis revealed a significantly increased serum Mn levels in PD patients (SMD=0.78; 95% CI [0.32, 1.24]; P=0.001), and it was further confirmed when serum, plasma and whole blood studies were analyzed together (SMD=0.58; 95% CI [0.25, 0.91]; P=0.001). Instead, no significant differences of CSF Mn were observed between PD patients and HC individuals (SMD= 0.09; 95% CI [-0.47, 0.29]; P=0.644). These results supported the notion that elevated Mn level should be a potential risk factor for PD, although the high heterogeneity and methodological limitations recommended caution in the interpretations for the present findings. PMID- 29191696 TI - Modulating effect of low intensity pulsed ultrasound on the phenotype of inflammatory cells. AB - AIMS: The purpose of this study was toclarify the effect of low intensity pulsed ultrasound (LIPUS) on the phenotype of the inflammatory infiltrate in muscle tissue following acute injury. MAIN METHODS: Forty Wistar rats were submitted to cryoinjury of the tibialis anterior muscle and only half were treated with LIPUS. After 1, 2, 3 and 7 days macrophages and neutrophils were quantified. KEY FINDINGS: With one day, LIPUS led to reductions in the number of neutrophils and M1 macrophages. After two days, muscles treated with LIPUS had fewer total macrophages and M1 macrophages, but a greater number of M2 macrophages. Muscles treated with LIPUS showed fewer macrophages after three and seven days. SIGNIFICANCE: As the permanence of cells with pro-inflammatory and anti inflammatory action can lead to the perpetuation of inflammation with consequent tissue damage and tissue fibrosis, respectively, the ability of LIPUS to modulate the occurrence of these cells demonstrates the therapeutic potential of this resource. PMID- 29191697 TI - Deliverable transgenics & gene therapy possibilities for the testes. AB - Male infertility and hypogonadism are clinically prevalent conditions with a high socioeconomic burden and are both linked to an increased risk in cardiovascular metabolic diseases and earlier mortality. Therefore, there is an urgent need to better understand the causes and develop new treatments for these conditions that affect millions of men. The accelerating advancement in gene editing and delivery technologies promises improvements in both diagnosis as well as affording the opportunity to develop bespoke treatment options which would both prove beneficial for the millions of individuals afflicted with these reproductive disorders. In this review, we summarise the systems developed and utilised for the delivery of gene therapy and discuss how each of these systems could be applied for the development of a gene therapy system in the testis and how they could be of use for the future diagnosis and repair of common male reproductive disorders. PMID- 29191698 TI - MicroRNAs-361-5p and miR-574-5p associate with human adipose morphology and regulate EBF1 expression in white adipose tissue. AB - Reduced adipose expression of the transcription factor Early B cell factor 1 (EBF1) is linked to white adipose tissue (WAT) hypertrophy. We aimed to identify microRNAs (miRNAs) associated with WAT hypertrophy and EBF1 regulation. We mapped WAT miRNA expression from 26 non-obese women discordant in WAT morphology and determined EBF1 activity in the non-obese and 30 obese women. Expression of 15 miRNAs was higher in hypertrophy and 10 were predicted to target EBF1. Binding of miR-365-5p/miR-574-5p were validated with 3'-UTR assay. Overexpression of miR-365 5p or miR-574-5p reduced EBF1 while inhibition of miR-574 increased EBF1 expression in human adipocytes in vitro. Additive effects on EBF1 were observed when concomitantly overexpressing both miRNAs. EBF1 targets were affected by over expression/inhibition of either miRNAs. Finally, miR-365-5p/miR-574-5p expression in 56 individuals correlated significantly with EBF1 activity. Our results suggest that miR-365-5p and miR-574-5p may be linked to WAT hypertrophy via effects on EBF1 expression. PMID- 29191699 TI - In vitro activity of new N-benzyl-1H-benzimidazol-2-amine derivatives against cutaneous, mucocutaneous and visceral Leishmania species. AB - The identification of specific therapeutic targets and the development of new drugs against leishmaniasis are urgently needed, since chemotherapy currently available for its treatment has several problems including many adverse side effects. In an effort to develop new antileishmanial drugs, in the present study a series of 28 N-benzyl-1H-benzimidazol-2-amine derivatives was synthesized and evaluated in vitro against Leishmania mexicana promastigotes. Compounds 7 and 8 with the highest antileishmanial activity (micromolar) and lower cytotoxicity than miltefosine and amphotericin B were selected to evaluate their activity against L. braziliensis 9and L. donovani, species causative of mucocutaneous and visceral leishmaniasis, respectively. Compound 7 showed significantly higher activity against L. braziliensis promastigotes than compound 8 and slightly lower than miltefosine. Compounds 7 and 8 had IC50 values in the micromolar range against the amastigote of L. mexicana and L. braziliensis. However, both compounds did not show better activity against L. donovani than miltefosine. Compound 8 showed the highest SI against both parasite stages of L. mexicana. In addition, compound 8 inhibited 68.27% the activity of recombinant L. mexicana arginase (LmARG), a therapeutic target for the treatment of leishmaniasis. Docking studies were also performed in order to establish the possible mechanism of action by which this compound exerts its inhibitory effect. Compound 8 shows promising potential for the development of more potent antileishmanial benzimidazole derivatives. PMID- 29191700 TI - Health Care Utilization in the First Month After Birth and Its Relationship to Newborn Weight Loss and Method of Feeding. AB - OBJECTIVE: Guidelines recommend closer outpatient follow-up for exclusively breastfed newborns, especially those with pronounced weight loss, because of increased risk of hyperbilirubinemia and dehydration that might require readmission. Our objective was to determine how feeding method and weight loss are associated with neonatal health care utilization. METHODS: A retrospective cohort study conducted at Northern California Kaiser Permanente hospitals in 2009 2013 assessed 143,889 neonates to study the inpatient method of feeding as well as inpatient and outpatient weights. The main outcome measures were inpatient and outpatient health care utilization in the 30 days after birth. RESULTS: Newborn weight loss and feeding method were both associated with utilization. Exclusively breastfed newborns had higher readmission rates than those exclusively formula fed for both vaginal (4.3% compared to 2.1%) (P < .001) and cesarean deliveries (2.1% compared to 1.5%) (P = .025). Those exclusively breastfed also had more neonatal outpatient visits compared to those exclusively formula fed for both vaginal (means of 3.0 and 2.3, P < .001) and cesarean deliveries (means of 2.8 and 2.2, P < .001). Among vaginally delivered newborns of all feeding types, newborns with weight loss >10% at discharge had a relative risk of readmission of 1.10 (95% confidence interval [CI],1.00, 1.20) compared to those with <8% weight loss at discharge; among the subset weighed as inpatients or outpatients between 48 and 72 hours, those with >10% weight loss between 48-72 hours had a relative risk of readmission of 2.11 (95% CI, 1.95, 2.26) compared to those with <8% weight loss at 48-72 hours. CONCLUSIONS: Exclusive breastfeeding and weight loss are associated with increased neonatal health care utilization. Improving clinical management of exclusively breastfed neonates with pronounced weight loss might reduce health care utilization. PMID- 29191701 TI - Back Pain and Body Posture Evaluation Instrument for Adults: Expansion and Reproducibility. AB - BACKGROUND: The BackPEI questionnaire was developed and validated just exclusively to evaluate children. AIMS: To propose, validate, and test the reproducibility of an expanded version of the Back Pain and Body Posture Evaluation Instrument (BackPEI), originally designed to assess back pain in school-aged children, for use with adults. DESIGN: Validation Study. METHODS: Five questions from the original BackPEI were replaced, resulting in the revised instrument (BackPEI-A) containing 20 questions. Three experts checked the content validity of the revised instrument, and the reproducibility was tested by trialing the questionnaire with 154 adults. RESULTS: The reproducibility data for the questions regarding pain intensity, analyzed using the Wilcoxon test and intraclass correlation coefficient (ICC), indicated that (a) there was no difference between the medians and (b) the answers were highly correlated, both for lower back (p = .574) (ICC = 0.908) and cervical (p = .968) (ICC = 0.865) pain. The reproducibility data for the remaining questions analyzed using the kappa coefficient were classified as moderate (0.4 < kappa <= 0.6) or very good (kappa > 0.8). CONCLUSION: The BackPEI-A is a reproducible, valid, and reliable instrument for use in the evaluation of back and neck pain and their associated risk factors. The instrument also facilitates the evaluation of postural habits in activities of daily living in adults. PMID- 29191702 TI - Association of initial recorded rhythm and underlying cardiac disease in sudden cardiac arrest. AB - BACKGROUND: Asystole (ASY) and pulseless electrical activity (PEA) are increasing and ventricular fibrillation (VF) or ventricular tachycardia (VT) declining as presenting rhythms of sudden cardiac arrest (SCA). Since there is limited information on possible differences in the etiology of underlying structural heart disease, we analyzed the clinical and/or autopsy findings of victims with ASY, PEA or VT/VF. METHODS: All SCA cases with recorded ASY, PEA or VT/VF occurring after onset of witnessed collapse were analyzed by the emergency personnel between the years 2007-2012 within the Oulu University Hospital area. Underlying structural heart disease was diagnosed by medico-legal autopsy or by clinical investigation (echocardiography, angiography). Of a total number of 659 subjects with a documented rhythm at the time of SCA, 300 were determined to be due to cardiac disease at autopsy or as a result of clinical investigation. Delay was less than 30min from collapse to rhythm recording in 274 subjects (mean age 65+/-14 yrs; 214 males, 78.1%). RESULTS: The presenting rhythm was ASY in 87 (31.8%) PEA in 38 (13.9%) and VT/VF in 149 subjects (54.4%). There was no significant difference in the delay from the onset of collapse to the rhythm recording between ASY (11+/-8min) and VT/VF (9+/-6min, p=0.06) or PEA (6+/-8min) and VT/VF (p=0.334). The majority of SCA subjects had an ischemic cause for the event (n=216, 78.8%). Non-ischemic cause for SCA was associated with non shockable rhythm (Non-ischemic: ASY 46.6% PEA 17.2% VT/VF 36.2% v. Ischemic: ASY 27.8% PEA 13.0% VT/VF 59.3%) even when adjusted for gender, age and delay from collapse to rhythm recording (ASY/PEA v. VT/VF, OR 3.2 95%CI: 1.67-6.50, p=0.001). CONCLUSIONS: Asystole and PEA are a more common presenting rhythm than VT/VF at the time of SCA in non-ischemic cardiac disease. The decreasing trend of ischemic heart disease as a cause of SCA may partly explain the increasing trend of ASY/PEA. PMID- 29191703 TI - Assessing health-related quality of life (HRQoL) in survivors of out-of-hospital cardiac arrest: A systematic review of patient-reported outcome measures. AB - AIM: High quality evidence of out-of-hospital cardiac arrest (OHCA) survivors' health-related quality of life (HRQoL) can measure the long-term impact of CA. The aim of this study was to critically appraise the evidence of psychometric quality and acceptability of measures used in the assessment of HRQoL in cardiac arrest survivors. METHODS: Systematic literature searches (2004-2017) and named author searches to identify articles pertaining to the measurement of HRQoL. Data on study quality, measurement and practical properties were extracted and assessed against international standards. RESULTS: From 356 reviewed abstracts, 69 articles were assessed in full. 25 provided evidence for 10 measures of HRQoL: one condition-specific; three generic profile measures; two generic index; and four utility measures. Although limited, evidence for measurement validity was strongest for the HUI3 and SF-36. However, evidence for reliability, content validity, responsiveness and interpretability and acceptability was generally limited or not available in the CA population for all measures. CONCLUSIONS: This review has demonstrated that a measure of quality of life specific to OHCA survivors is not available. Limited evidence of validity exists for one utility measure - the HUI3 - and a generic profile - the SF-36. Robust evidence of the quality and acceptability of HRQoL measures in OHCA was limited or not available. Future collaborative research must seek to urgently establish the relevance and acceptability of these measures to OHCA survivors, to establish robust evidence of essential measurement and practical properties over the short and long-term, and to inform future HRQoL assessment in the OHCA population. PMID- 29191704 TI - Microfouling inhibition of human nosocomial pathogen Pseudomonas aeruginosa using marine cyanobacteria. AB - Pseudomonas aeruginosa is a Gram negative, opportunistic biofilm forming pathogenic bacterium which is developing as a serious problem worldwide. The pathogenicity of P. aeruginosa mainly depends upon biofilm and quorum sensing (QS) mechanism. Targeting biofilm and QS regulated factor will automatically reduce the pathogenicity of P. aeruginosa. Therefore it is compulsory to identify naturally derived biofilm and QS inhibitors against P. aeruginosa. In the present study Oscillatoria subuliformis, a marine cyanobacterium was used against the biofilm and QS of P. aeruginosa. O. subuliformis intracellular methanolic extract (OME) at different concentration (1.5 MUg mL-1, 3 MUg mL-1 and 5 MUg mL-1) was tested against several virulence factors like Extracellular Polymeric Substance (EPS), Cell Surface Hydrophobicity (CSH), elastase, pyocyanin and swarming motility. OME inhibited biofilm (56%), EPS (40%), CSH (56%), pyocyanin (27%), elastase activity and swarming motility in P. aeruginosa without interfering in their survival. Characterization of the OME using FTIR and GCMS confirmed palmitic acid and oleic acid as active compound. CLSM analysis of catheter coated with OME, palmitic and oleic acid proved biofilm inhibition over urinary catheters. The results postulates that oleic and palmitic acid could be an effective attenuator of P. aeruginosa pathogenesis. PMID- 29191705 TI - Integrated analysis of miRNA and mRNA expression profiling in bovine endometrial cells in response to lipopolysaccharide-stimulation. AB - MicroRNAs (miRNA) play an important role in regulating gene expression, making them important resources for exploring molecular mechanisms. Molecular mechanisms involved in the inflammatory responses of bovine endometrial cells induced by lipopolysaccharide (LPS) have not been widely studied. In the present study, miRNA and mRNA expression profiling of bovine endometrial cells treated with 1 MUg/mL LPS for 24 h were evaluated by RNA-Seq (RNA-sequencing). The results showed that LPS induced 20 (11 up- and 9 down-regulated) differentially-expressed miRNAs and 108 (90 up- and 18 down-regulated) differentially-expressed mRNAs of bovine endometrial cells. The results for 5 mRNAs and 4 miRNAs were evaluated by quantitative real-time PCR (qRT-PCR) to validate the reliability of the RNA-seq data. Integrating analysis of the miRNA and mRNA expression profiles revealed 116 miRNA-target gene pairs. GO and KEGG pathway analysis of differentially expressed miRNAs and target genes predicted the likely roles of differentially expressed miRNAs in inflammatory responses in bovine endometrial cells induced by LPS. The reliability of the integrating analysis of the miRNA and mRNA data were validated by measuring the expression of three miRNA-target gene pairs by qRT-PCR. Our results improve the understanding of the role of miRNA involvement in inflammatory response of bovine endometrial cells induced by LPS. PMID- 29191706 TI - Biological control of the Pulse beetle, Callosobruchus maculatus in stored grains using the entomopathogenic bacteria, Bacillus thuringiensis. AB - In the present study, we reported the biological control of stored product insect pest, Callosobruchus maculatus using the entomopathogenic bacteria, Bacillus thuringiensis. A significant delay in the larval, pupal and total development period of C. maculatus was observed after treatment with B. thuringiensis at 4 * 108 cells/mL. Furthermore, B. thuringiensis are highly effective in the control of C. maculatus and produced 100% mortality at 4 * 108 cells/mL. The LC50 value was estimated to be 3 * 107 cells/mL. In addition, a significant decrease in the activity of mid-gut alpha-amylase, cysteine protease, alpha & beta-glucosidases, lipase, glutathione S-transferase (GST) and lactate dehydrogenase (LDH) was observed after treatment with B. thuringiensis at 4 * 108 cells/mL. This study concludes that B. thuringiensis are more effective against C. maculatus and could be used as a potential biological control agent in the management of stored product insect pests in the future. PMID- 29191707 TI - Changes in inflammatory/cardiac markers of HIV positive patients. AB - : HIV replication promotes atherogenesis and participates in the immune response to the virus, thereby influencing the inflammatory profile. These changes may, in turn, contribute to the risk of cardiovascular diseases with involvement of platelets. However, adenine nucleotides and nucleosides involved in thromboregulation and modulation of immune response may therefore be affected by these alterations. OBJECTIVES: This study sought to evaluate the profile of pro and anti-inflammatory cytokines (IL-10, IL-6, IL-17, TNF, IL-4, IL-2 and IFN gamma), cardiac markers (troponin, CK, CK MB, LDH, CRP) in HIV-positive patients and assess the in vitro effect of antiretroviral therapy on the activities of ectonucleotidases (E-NTPDase and E-5'-nucleotidase) in human platelets. DESIGN AND METHODS: Blood samples were obtained from ten HIV positive patients at the Infectious Disease Clinic of the University Hospital of Santa Maria, Brazil and ten HIV negative individuals (control group) for this study. RESULTS: The results revealed that there were significant (P < 0.05) increases in serum levels of IL-6 and IFN-gamma with no significant (P > 0.05) changes in the serum levels of the cardiac markers investigated (CK, CK-MB, troponin, LDH and CRP). In addition, the ectonucleotidases (E-NTPDase and E-5'-nucleotidase) activities were not altered (P > 0.05) in human platelets when incubated with different antiretroviral drugs in vitro. CONCLUSIONS: The results of this study suggest that, despite successful treatment, a proinflammatory state is not altered in HIV patients, and that antiretroviral therapy per se does not change the purinergic profile. PMID- 29191708 TI - Neuroprotective effect of (-)-tetrahydropalmatine in Japanese encephalitis virus strain GP-78 infected mouse model. AB - Japanese encephalitis virus (JEV), known to affect children, is a major cause of severe encephalopathy. Its prevalence has been percolated over wider regions of Southern Asia. JEV is associated with neurodegeneration, severe inflammation, increased oxidative stress and elevated levels of stress linked proteins. Four groups of 15 mice each (4-5 weeks old BALB/c mice of either sex) was used for the study. Mice were intravenously infected with lethal dose of 3 * 105 pfu of JEV, followed by mortality after 8 days. On the next day and onwards, the animals were administered intraperitonially with (-)-tetrahydropalmatine (LTHP) solution (0.1 mg/mL in PBS) for the next 7 days. Animals exhibited protection against JEV infection, after being administered with LTHP. Reduction in levels of, viral population, caspase-2 expression, reactive oxygen and nitrogen species, microglial cells and proinflammatory mediators, stress linked protein molecules and neuronal apoptosis was exhibited in JEV infected animals treated with LTHP. The effects produced by the administration of LTHP indicated its possible use to treat JEV in mouse model. Potential to reduce viral count in brain and subsequent neuronal apoptosis, reduction in mediators of inflammation and oxidative stress, strictly advocate the use of LTHP for treatment of JEV. Thus, the present investigation indorses LTHP as a potentially strong drug candidate for the treatment of JEV infection due to its neuroprotective, anti-inflammatory, antiviral and anti-oxidative effect. PMID- 29191709 TI - Strigolactones promote rhizobia interaction and increase nodulation in soybean (Glycine max). AB - Strigolactones (SLs) play an important role in controlling root growth, shoot branching, and plant-symbionts interaction. Despite the importance, the components of SL biosynthesis and signaling have not been unequivocally explored in soybean. Here we identified the putative components of SL synthesis enzymes GmMAX1a and GmMAX4a with tissue expression patterns and were apparently regulated by rhizobia infection and changed during nodule development. GmMAX1a and GmMAX4a were further characterized in soybean nodulation with knockdown transgenic hairy roots. GmMAX1a and GmMAX4a knockdown lines exhibit decreased nodule number and expression levels of several nodulation genes required for nodule development. Hormone analysis showed that GmMAX1a and GmMAX4a knockdown hairy roots had increased physiological level of ABA and JA but significantly decreased auxin content. This study not only revealed the conservation of SL biosynthesis but also showed close interactions between SL and other hormone signaling in controlling plant development and legume-rhizobia interaction.

PMID- 29191711 TI - Analyzing test batteries in animal models of psychopathology with multivariate analysis of variance (MANOVA): One possible approach to increase external validity. AB - BACKGROUND: One concern regarding animal models of psychopathology is unclear external validity. One way to establish external validity is to examine measures representing separate facets of the pathology with a battery of tests in the same cohort of animals. Additionally, utilizing the same animals in a battery of tests can help to reduce the number of animals in research. However, issues had been raised regarding the analysis of data coming from batteries and the standard practice is to analyze each test separately. This approach introduces two problems: (1) the analysis answers the question regarding separate tests but not regarding the general effect; (2) there is no correction for multiple comparisons. One way to overcome these challenges is to use transformations to Z scores. We suggest an additional approach, analyzing test batteries with multivariate analysis of variance (MANOVA). METHODS: To compare the outcomes of Z score analysis and MANOVA we re-analyzed two published studies where data were initially analyzed separately for each test. Additionally, we computed effect sizes. RESULTS: The first study tested interaction between sex and lithium in a battery of manic-like behaviors, the second study tested asenapine in a battery of anxiety-like behaviors. For the first study, the MANOVA analysis indicated no effects of sex and a significant antimanic-like effect of lithium and for the second study, the MANOVA indicated a significant anxiolytic effect of asenapine. Z-score analysis resulted in a significant general antimanic-like effect in the lithium study but failed to demonstrate the anxiolytic effects of asenapine in the second study. CONCLUSIONS: It is possible to suggest that MANOVA is an appropriate way to analyze data from test batteries and that its use, when appropriate, can increase the validity, predictability and reproducibility of results. PMID- 29191712 TI - Biochemical and physiological effects of nickel in the euryhaline crab Neohelice granulata (Dana, 1851) acclimated to different salinities. AB - The estuarine crab Neohelice granulata was maintained under control condition or exposed to sublethal concentrations of dissolved Ni (measured: 128 and 1010MUg/L) for 96h at different salinities (2 and 30ppt). After metal exposure, whole-body oxygen consumption was measured and tissue (hemolymph, gills, hepatopancreas and muscle) samples were collected. Control crabs acclimated to 2ppt salinity showed lower hemolymph concentrations of Na+ (33%), Mg2+ (19%) and K+ (30%), as well as increased LPO levels in anterior gills (379%), posterior gills (457%) and hepatopancreas (35%) with respect to those acclimated to 30ppt salinity. In crabs acclimated to 2ppt salinity, Ni exposure increased whole-body oxygen consumption (75%), hemolymph K+ concentration (52%), hemolymph (135%) and hepatopancreas (62%) LDH activity. Also, it reduced hemolymph Cl- concentration (16%) and muscle LDH activity (33%). In crabs acclimated to 30ppt salinity, Ni exposure increased LDH activity in hemolymph (195%), hepatopancreas (126%) and muscle (53%), as well as hemolymph osmolality (10%), Cl- (26%) and Ca2+ (20%) concentration. It also reduced hepatopancreas lipid peroxidation (20%) and hemolymph Mg2+ (29%) and K+ (31%) concentration. These findings indicate that N. granulata is hyper osmoregulating in 2ppt salinity and hypo-regulating in 30ppt salinity, showing adjustments of hemolymph ionic composition and metabolic rates, with consequent higher oxidative damage to lipids in low salinity (2ppt). Ni effects are associated with metabolic (aerobic and anaerobic) disturbances in crabs acclimated to 2ppt salinity, while osmotic and ionoregulatory disturbances were more evident in crabs acclimated to 30ppt salinity. PMID- 29191713 TI - Assessment of right atrial function with speckle tracking echocardiography after percutaneous closure of an atrial septal defect. AB - INTRODUCTION: Speckle tracking echocardiography (STE) for two-dimensional (2D) strain analysis is a new tool to assess myocardial function. The aim of this study was to assess right atrial (RA) function using STE in patients with an atrial septal defect (ASD) before and one month after percutaneous closure. METHODS: We prospectively examined 32 consecutive patients (nine male, 23 female) who underwent percutaneous transcatheter closure of a secundum ASD between June 2013 and December 2015. Echocardiography was performed on admission, prior to cardiac catheterization and then one month after ASD closure. Peak global RA longitudinal strain was analyzed by 2D-STE. RESULTS: Patients' mean age was 34.6+/-8.2 years. The mean diameter of the occlusive devices was 18.5+/-7.5 mm. Right ventricular (RV) end-diastolic diameters were significantly increased but decreased significantly after ASD closure (43+/-5 vs. 38+/-4 mm, p<0.05). Left atrial (LA) diameters (40+/-8 vs. 37+/-6 mm, p<0.05) decreased significantly after the intervention, whereas left ventricular (LV) end-diastolic diameters (45+/-5 vs. 46+/-4 mm, NS) remained unchanged. Tricuspid annular plane systolic excursion increased significantly (17.6+/-5.4 vs. 22.3+/-8.1 mm, p<0.05). After closure of the defect, a significant increase was observed in longitudinal RA strain (26.5+/-9.6% vs. 35.3+/-10.5%, p<0.001). CONCLUSIONS: After percutaneous transcatheter closure of a secundum ASD, there was an increase in RA longitudinal strain. 2D-STE strain analysis appears to be helpful for the assessment of RA function and of response to correction of volume overload after percutaneous transcatheter closure of a secundum ASD. PMID- 29191714 TI - Subcutaneous immunoglobulins in patients with multiple myeloma and secondary hypogammaglobulinemia: a randomized trial. AB - Multiple myeloma is commonly associated with a reduction of non-paraprotein immunoglobulins, resulting in a higher risk of infections that represent the leading cause of the patients' death. Therefore, immunoglobulin replacement therapy appears a logical approach. A total number of 46 myeloma patients were randomly enrolled: 24 of them were assigned to receive subcutaneous immunoglobulins, and 22 were controls. The primary endpoint was the evaluation of the annual rate of severe infections in immunoglobulins-receiving patients as compared with those untreated. Subcutaneous immunoglobulins-treated patients showed a significantly lower number of severe infections per year. Adverse events were limited to the site of infusion and were easily manageable. Health-related quality of life was significantly better in subcutaneous immunoglobulins receiving patients. By decreasing the rate of infections, the prophylactic administration of SCIg improves both adherence to chemotherapy and health-related quality of life, and is cost-effective by reducing the need of hospitalization and the use of antibiotics. PMID- 29191715 TI - VcR-CVAD Induction Chemotherapy Followed by Maintenance Rituximab Produces Durable Remissions in Mantle Cell Lymphoma: A Wisconsin Oncology Network Study. AB - INTRODUCTION: VcR-CVAD was developed as an intermediate-intensity induction regimen with maintenance rituximab (MR) to improve remission durations after first-line therapy for mantle cell lymphoma (MCL) in older and younger patients with MCL. PATIENTS AND METHODS: Patients with previously untreated MCL received VcR-CVAD induction chemotherapy for 6 cycles (21-day cycles). Patients achieving at least a partial response received rituximab consolidation (375 mg/m2 * 4 weekly doses) and MR (375 mg/m2 every 12 weeks * 20 doses). The primary endpoints were overall and complete response (CR), and the secondary endpoints were progression-free survival (PFS) and overall survival (OS). Thirty patients were enrolled, with a median age of 61 years. There was an even distribution of patients < 60 years and >= 60 years. Mantle cell lymphoma international prognostic index medium- or high-risk disease was present in 60%. The overall response rate observed was 90% (77% CR/unconfirmed CR). After a median follow-up of 7.8 years, the 6-year PFS and OS were 53% and 70%, respectively. There was no difference in 6-year PFS or OS between the younger (age < 60 years) and older (age >= 60 years) subgroups. In a univariate analysis, lactate dehydrogenase, when analyzed for interaction with age, had a significant effect on PFS outcomes at 6 years. There were no pretreatment variables determined to have a significant effect on OS outcomes at 6 years. CONCLUSIONS: Long-term outcomes with VcR-CVAD are comparable with more intensive inductions and consolidation approaches. MCL is biologically heterogeneous, and durable remission can be achieved with intermediate intensity therapy. MR appears to contribute to these excellent outcomes. PMID- 29191716 TI - Pulmonary absorption - estimation of effective pulmonary permeability and tissue retention of ten drugs using an ex vivo rat model and computational analysis. AB - Permeation of inhaled drugs across the pulmonary epithelium can regulate the rate and extent of local drug absorption and hence the pulmonary tissue concentration. Therefore, understanding pulmonary epithelial transport could be important for successful design of novel inhaled medicines. To enhance understanding of pulmonary epithelial transport, drug transport data were generated for a set of inhaled compounds (n = 10) in the single-pass, isolated perfused rat lung model. A compartmental in silico model was used to estimate pulmonary permeability and tissue retention. The theoretical model was also used to re-analyze previously obtained historical drug transport data from the isolated perfused lung (n = 10) with re-circulating buffer. This was performed to evaluate the re-circulating model for assessing tissue retention measurements and to increase the number of data points. The tissue retention was an important parameter to estimate to be able to describe the drug transport profiles accurately of most of the investigated compounds. A relationship between the pulmonary permeability and the intrinsic (carrier-mediated transport inhibited) permeability of Caco-2 cell monolayers (n = 1-6) was also established. This correlation (R2 = 0.76, p < .0001) suggests that intrinsic Caco-2 permeability measurements could offer early predictions of the passive transcellular permeability of lung epithelium to candidate drugs. Although, for some compounds a deviation from the correlation suggests that other transport mechanisms may coexist. The compartmental in silico model was successful in describing the pulmonary drug transport profiles of the investigated compounds and has potential for further development to investigate the effects of formulations with different features on the pulmonary overall absorption rate. PMID- 29191717 TI - Improved in vitro models for preclinical drug and formulation screening focusing on 2D and 3D skin and cornea constructs. AB - The present overview deals with current approaches for the improvement of in vitro models for preclinical drug and formulation screening which were elaborated in a joint project at the Center of Pharmaceutical Engineering of the TU Braunschweig. Within this project a special focus was laid on the enhancement of skin and cornea models. For this reason, first, a computation-based approach for in silico modeling of dermal cell proliferation and differentiation was developed. The simulation should for example enhance the understanding of the performed 2D in vitro tests on the antiproliferative effect of hyperforin. A second approach aimed at establishing in vivo-like dynamic conditions in in vitro drug absorption studies in contrast to the commonly used static conditions. The reported Dynamic Micro Tissue Engineering System (DynaMiTES) combines the advantages of in vitro cell culture models and microfluidic systems for the emulation of dynamic drug absorption at different physiological barriers and, later, for the investigation of dynamic culture conditions. Finally, cryopreserved shipping was investigated for a human hemicornea construct. As the implementation of a tissue-engineering laboratory is time-consuming and cost intensive, commercial availability of advanced 3D human tissue is preferred from a variety of companies. However, for shipping purposes cryopreservation is a challenge to maintain the same quality and performance of the tissue in the laboratory of both, the provider and the customer.

AB - This paper discusses the "non-reception" of Darwin's works and concepts in French palaeontology and palaeoanthropology between 1859 and 1914. Indeed, this integration was difficult, biased and belated, for ideological, intellectual and epistemological reasons: Clemence Royer's biased 1862 translation of Darwin's Origin of Species pulled its ideas toward "social darwinism", making them less attractive to the natural sciences. - French nationalism and the authority of religion, which imposed Cuvier's thinking until late into the century - the dominance of Lamarckian and neo-Lamarckian transformism in France, both in biology and in paleontology, which proposed the notion of orthogenetic laws and environmental determinations, and refused darwinian evolutionary mechanisms - obstacles inherent to the application of Darwin's concepts to palaeontology, namely the impossibility to identify evolutionary mechanisms through the fossil record, which was stressed by Darwin himself and underlined in turn by 19th century French palaeontologists. However, as I argue, in the course of the examined period, French palaeontology grew from refusal to a better understanding and evaluation of Darwin's thinking. The quest for intermediary forms, the construction of branching evolutionary trees and the attempts to reconstruct human biological and cultural evolution were important efforts toward an integration of some aspects of Darwinian views and practices into French palaeontology and plaeoanthropology. The 1947 Paris conference which brought together American Neo-darwinists and French paleontologists made Darwinian concepts better understood and triggered a revival of French palaeontology from the 1960s. PMID- 29191719 TI - JAK/STAT - Emerging Players in Metabolism. AB - The Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway is crucial for transducing signals from a variety of metabolically relevant hormones and cytokines including growth hormone, leptin, erythropoietin, IL4, IL6 and IFNgamma. A growing body of evidence suggests that this pathway is dysregulated in the context of obesity and metabolic disease. Recent development of animal models has been instrumental in identifying the role of JAK/STAT signaling in the peripheral metabolic organs including adipose, liver, muscle, pancreas, and the immune system. In this review we summarize current knowledge about the function of JAK/STAT proteins in the regulation of metabolism, and highlight new potential therapeutic targets for the treatment of obesity and diabetes.

AB - CONTEXT: Stroke is the second leading cause of death and the primary cause of disability worldwide. It is uncertain what care patients with stroke receive in their end of life and what trends in care are in recent years. OBJECTIVES: The objective of this study was to investigate the changes in the use of intensive and supportive procedures for Taiwanese patients with stroke in their last month of life during 2000-2010. METHODS: Analysis of claims data of 55,930 patients with stroke obtained from the National Health Insurance Research Database was performed to investigate the changes in the use of intensive and supportive procedures for Taiwanese patients with stroke in their last month of life during 2000-2010. RESULTS: Over the whole study period, 25.4% of patients with stroke were admitted to intensive care units in their last month of life. The percentages of patients receiving mechanical ventilation (77.4%-67.9%), cardiopulmonary resuscitation (53.8%-35.8%), and inotropic agents (73.5%-64.3%) decreased over time. The percentages of patients receiving artificial hydration and nutrition (65.9%-73.3%) and sedative or analgesic agents (34.7%-38.6%) increased over time. Patients under 85 years old were more likely to be admitted to intensive care units. Men were more likely to receive mechanical ventilation and cardiopulmonary resuscitation than women. CONCLUSION: Over time, the use of supportive procedures increased, and the use of intensive procedures decreased in patients with stroke in the last month of life. This study highlights a need for research, guidelines, and training in how to provide palliative care for end stage patients with stroke.

PMID- 29191724 TI - Moral Distress at the End of a Life: When Family and Clinicians Do Not Agree on Implantable Cardioverter-Defibrillator Deactivation. AB - A 63-year-old man with end-stage ischemic cardiomyopathy presented with incessant ventricular tachycardia. He had been hospitalized multiple times in the past year for severe heart failure. As he approached end of life and was regularly receiving defibrillator shocks, his care team recommended deactivation of his implantable cardioverter-defibrillator. However, his family did not wish to allow deactivation, reporting a religious obligation to prolong his life, regardless of the risk of suffering. The patient was unable to adequately participate in the decision-making process. An implantable cardioverter-defibrillator can serve to avoid sudden death but may lead to a prolonged death from heart failure. This possibility forces the examination of values regarding prolongation of life, sometimes producing disagreement among stakeholders. Although ethical consensus holds that defibrillator deactivation is legal and ethical, disagreements about life prolongation may complicate decision making. The ethical, technical, and medical complexity involved in this case speaks to the need for clear, prospective communication involving the patient, the patient's family, and members of the care team. PMID- 29191725 TI - Bonding in neonatal intensive care units: Experiences of extremely preterm infants' mothers. AB - BACKGROUND: The birth of an extremely preterm infant can disrupt normal mother infant physical contact and the care provided by the mother. This situation has an impact on the process of bonding between the mother and the child. AIM: The objective of this study was to describe and understand the experiences of mothers who have extremely preterm infants admitted in Neonatal Intensive Care Units with regard to their bonding process. METHODS: An interpretive, qualitative research methodology using Gadamer's philosophical hermeneutics was carried out. A focus group and eleven in-depth, semi-structured interviews were conducted. Data were collected between June and September of 2016. FINDINGS: Sixteen women with a mean age of 34.4 years participated in the study. Two themes emerged from the data analysis: (1) premature labour and technological environment, a distorted motherhood, with the subthemes 'feeling of emptiness and emotional crisis' and 'the complexity of the environment and care generate an emotional swing'; (2) learning to be the mother of an extremely preterm infant, with the subthemes "the difficulty of relating to a stranger" and 'forming the bond in spite of difficulties'. CONCLUSIONS: The bonding with extremely preterm infants is interrupted after giving birth. The maternal emotional state and the environment of the neonatal intensive care unit limit its development. Nursing care can facilitate mother-infant bonding by encouraging communication, participation in care, massaging or breastfeeding. PMID- 29191726 TI - Essential oils of culinary herbs and spices display agonist and antagonist activities at human aryl hydrocarbon receptor AhR. AB - Essential oils (EOs) of culinary herbs and spices are used to flavor, color and preserve foods and drinks. Dietary intake of EOs is significant, deserving an attention of toxicologists. We examined the effects of 31 EOs of culinary herbs and spices on the transcriptional activity of human aryl hydrocarbon receptor (AhR), which is a pivotal xenobiotic sensor, having also multiple roles in human physiology. Tested EOs were sorted out into AhR-inactive ones (14 EOs) and AhR active ones, including full agonists (cumin, jasmine, vanilla, bay leaf), partial agonists (cloves, dill, thyme, nutmeg, oregano) and antagonists (tarragon, caraway, turmeric, lovage, fennel, spearmint, star anise, anise). Major constituents (>10%) of AhR-active EOs were studied in more detail. We identified AhR partial agonists (carvacrol, ligustilide, eugenol, eugenyl acetate, thymol, ar-turmerone) and antagonists (trans-anethole, butylidine phtalide, R/S-carvones, p-cymene), which account for AhR-mediated activities of EOs of fennel, anise, star anise, caraway, spearmint, tarragon, cloves, dill, turmeric, lovage, thyme and oregano. We also show that AhR-mediated effects of some individual constituents of EOs differ from those manifested in mixtures. In conclusion, EOs of culinary herbs and spices are agonists and antagonists of human AhR, implying a potential for food-drug interactions and interference with endocrine pathways. PMID- 29191727 TI - Stable PEG-coated silver nanoparticles - A comprehensive toxicological profile. AB - The present study was purported to assess the toxicological profile of bare and polyethylene glycol (PEG) coated spherical silver nanoparticles (AgNPs) by means of in vitro (on human keratinocytes - HaCat cells) and in vivo non-invasive tests (after intraperitoneal - i.p. administration to mice). Bare and PEG-coated AgNPs were synthesized by applying Turkevich's method slightly modified. The physico chemical characterization revealed the formation of stable, spherical AgNPs and PEG-AgNPs, with narrow size distributions and mean hydrodynamic sizes in the range of 19 nm and 50 nm, respectively. Toxicity data revealed a dose-dependent safe profile for low concentrations of test compounds (<10 MUM) in terms of cell viability, whereas higher concentrations were associated with a high rate of cell mortality. In vivo acute/subacute toxicity data showed no denotive changes in mice health status after i.p. administration. Histological observations of internal organs and the biochemical parameters analyzed together with the other biological observations showed a low toxicity level with no major differences related to control, albeit at skin level a reduced number of mast cells was detected. All these observations provide strong support for the idea that coated silver nanoparticles could be applied as targeted nanocarriers for skin pathologies and diagnostic. PMID- 29191728 TI - The sp2-iminosugar glycolipid 1-dodecylsulfonyl-5N,6O-oxomethylidenenojirimycin (DSO2-ONJ) as selective anti-inflammatory agent by modulation of hemeoxygenase-1 in Bv.2 microglial cells and retinal explants. AB - Neuroinflammation is an early event during diabetic retinopathy (DR) that impacts the dynamics of microglia polarization. Gliosis is a hallmark of DR and we have reported the beneficial effects of 1R-DSO-ONJ, a member of the sp2-iminosugar glycolipid (sp2-IGL) family, in targeting microglia and reducing gliosis in diabetic db/db mice. Herein, we analyzed the effect of DSO2-ONJ, another family compound incorporating a sulfone group that better mimics the phosphate group of phosphatidylinositol ether lipid analogues (PIAs), in Bv.2 microglial cells treated with bacterial lipopolysaccaride (LPS) and in retinal explants from db/db mice. In addition to decreasing iNOS and inflammasome activation, the anti inflammatory effect of DSO2-ONJ was mediated by direct p38alpha MAPK activation. Computational docking experiments demonstrated that DSO2-ONJ binds to p38alpha MAPK at the same site where PIAs and the alkyl phospholipid perifosine activators do, suggesting similar mechanism of action. Moreover, treatment of microglial cells with DSO2-ONJ increased both heme-oxygenase (HO)-1 and Il10 expression regardless the presence of LPS. In retinal explants from db/db mice, DSO2-ONJ also induced HO-1 and reduced gliosis. Since IL-10-mediated induction of HO-1 expression is mediated by p38alpha MAPK activation, our results suggest that this molecular mechanism is involved in the anti-inflammatory effects of DSO2-ONJ in microglia. PMID- 29191729 TI - Hardness and posting of foot orthoses modify plantar contact area, plantar pressure, and perceived comfort when cycling. AB - OBJECTIVES: To evaluate the effects of hardness and posting of orthoses on plantar profile and perceived comfort and support during cycling. DESIGN: A repeated measures study with randomised order of orthoses, hardness, and posting conditions. METHODS: Twenty-three cyclists cycled at a cadence of 90rpm and a perceived exertion rating of twelve. Contoured soft and hard orthoses with or without a medial forefoot or lateral forefoot post were evaluated. Plantar contact area, mean pressure and peak pressure were measured for nine plantar regions using the pedar(r)-X system and represented as a percentage of the total (CA%, MP%, and PP% respectively). Perceived comfort and support was rated on a visual analogue scale. RESULTS: The softer orthosis significantly increased CA% (p=0.014) across the midfoot and heel with a decrease in the toe region and forefoot. MP% (p=0.034) and PP% (p=0.012) were significantly increased at the mid and lateral forefoot with reductions in MP% at the midfoot and in PP% at the hallux and toes. Forefoot posting significantly increased CA% (p=0.018) at the toes and forefoot and decreased it at the heel. PP% was significantly altered (p=0.013) based on posting position. Lateral forefoot posting significantly decreased heel comfort (p=0.036). CONCLUSION: When cycling, a soft, contoured orthosis increased contact across the midfoot and heel, modulating forefoot and midfoot plantar pressures but not altering comfort or support. Forefoot postings significantly modified contact areas and plantar pressures and reduced comfort at the heel. PMID- 29191730 TI - Clinical Outcome of Isolated Tricuspid Regurgitation in Patients with Preserved Left Ventricular Ejection Fraction and Pulmonary Hypertension. AB - BACKGROUND: The outcome of tricuspid regurgitation (TR) remains unclear because of heterogeneity of etiology and the contradictory results of outcome studies. The aim of this study was to evaluate the clinical outcomes of TR in patients with pulmonary hypertension (PH) and normal left systolic function, stratified to patients with post- or precapillary PH. METHODS: In patients with no left valvar disease (isolated) functional TR, preserved left systolic function (ejection fraction >= 50%), and PH (systolic pulmonary pressure > 50 mm Hg), TR was assessed both qualitatively (grade) and semiquantitatively using the vena contracta method, and retrospective analysis of long-term outcomes was conducted. Patients with severe comorbid diseases were excluded. RESULTS: The study included 245 patients (age 80.5 years, 37% men, ejection fraction 57%, all with pulmonary systolic pressure > 50 mm Hg). At least moderate to severe TR was diagnosed in 178 patients, and their outcomes were compared with those of 67 patients with the same characteristics and less than mild TR. At least moderate to severe TR was associated with lower survival, independent of all characteristics, right ventricular size or function, comorbidity, or pulmonary pressure (P = .03 for grade and P = .02 for vena contracta). Cox proportional-hazard analysis with interaction terms for TR severity and etiology of PH (post- vs precapillary) showed that the etiology of PH did not affect the association of TR with outcome (P = .90 for the interaction term). CONCLUSIONS: At least moderate to severe isolated TR is independently associated with excess mortality in patients with preserved systolic function and PH, warranting heightened attention to diagnosis and grading. This is irrespective of etiology (pre- or postcapillary) of PH. Semiquantitative assessment of TR by vena contracta is an independent associate of outcome, superior to standard qualitative assessment. PMID- 29191731 TI - Characteristic Morphologies of the Bicuspid Aortic Valve in Patients with Genetic Syndromes. AB - BACKGROUND: In patients with bicuspid aortic valve (BAV), complications including progressive aortic stenosis and aortic dilatation develop over time. The morphology of cusp fusion is one of the determinants of the type and severity of these complications. We present the association of morphology of cusp fusion in BAV patients with distinctive genetic syndromes. METHODS: The Mayo Clinic echocardiography database was retrospectively reviewed to identify patients (age <= 22 years) diagnosed with BAV from 1990 to 2016. Cusp fusion morphology was determined from the echocardiographic studies, while coexisting cardiac defects and genetic syndromes were determined from chart review. RESULTS: A total of 1,037 patients with BAV were identified: 550 (53%) had an isolated BAV, 299 (29%) had BAV and a coexisting congenital heart defect, and 188 (18%) had BAV and a coexisting genetic syndrome or disorder. There were no differences in distribution of morphology across the three groups. However, right-noncoronary (RN) cusp fusion was the predominant morphology associated with Down syndrome (P = .002) and right-left (RL) cusp fusion was the predominant morphology associated with Turner syndrome (P = .02), DiGeorge syndrome (P = .02), and Shone syndrome (P = .0007), when compared with valve morphology in patients with isolated BAV. Isolated BAV patients with RN cusp fusion had larger ascending aorta diameter (P = .001) and higher number of patients with >= moderate aortic regurgitation (P = .02), while those with RL cusp fusion had larger sinus of Valsalva diameter (P = .0006). CONCLUSIONS: Morphological subtypes of BAV are associated with different genetic syndromes, suggesting distinct perturbations of developmental pathways in aortic valve malformation. PMID- 29191732 TI - Quantification of Aortic Valve Regurgitation by Pulsed Doppler Examination of the Left Subclavian Artery Velocity Contour: A Validation Study with Cardiovascular Magnetic Resonance Imaging. AB - BACKGROUND: Reflux of the aortic regurgitation (AR) causes an increased diastolic reverse flow in the aorta and its branching vessels. We aimed to evaluate the feasibility and accuracy of Doppler measurements in the left subclavian artery (LSA) for quantification of AR in a cardiovascular magnetic resonance imaging (CMR) validation study. METHODS: Systolic and diastolic flow profiles of the LSA (subclavicular approach) were evaluated prospectively by use of pulsed wave Doppler in 59 patients (55.5 +/- 15 years; 44 men), 47 with a wide spectrum of AR and 12 as control group. Using CMR phase-contrast sequences (performed 1 cm above the aortic valve), the AR was divided into three groups: mild, regurgitant fraction (RF) < 20% (n = 17); moderate, RF 20%-40% (n = 10); and severe, RF > 40% (n = 20). The LSA Doppler-derived RF was calculated as the ratio between diastolic and systolic velocity-time integrals (VTI). RESULTS: Quality LSA Doppler signal could be obtained in all cases. Patients with CMR severe AR had higher values of LSA Doppler-derived RF (51% +/- 9% vs 36% +/- 11% vs 16% +/- 8%; P < .0001). LSA Doppler showed a good correlation with CMR, with a sensitivity of 95%, specificity of 89%, and diagnostic accuracy for severe AR of 91.5%. Finally, Bland-Altman plots showed agreement in the group with moderate to severe AR (mean bias = -2.2% +/- 8%, 95% CI, -17.7 to 13.3; P = .145) but differed in mild AR. CONCLUSIONS: Measurements of the RF for quantification of AR using LSA Doppler are comparable to those of CMR, highlighting the potential role of LSA Doppler as an adjunctive technique to assess the severity of AR. PMID- 29191734 TI - Splenomegaly: Pathophysiological bases and therapeutic options. AB - The spleen is the largest immune organ in the human body and is also essential for red blood cell homeostasis and iron recycling. An average human spleen is approximately 10 centimetres in length and weighs 150g. Pathological conditions can result in the spleen weighing in excess of 2000g and extending over 30 centrimetres in length. This remarkable property of the spleen to expand is termed splenomegaly. Splenomegaly can occur as a physiological response to stress or as a chronic process that is often detrimental to the wellbeing of the individual. Here, we will discuss the normal function and physiology of the spleen, the pathophysiological bases of splenomegaly and the commonly available therapeutic options. Additionally we will address experimental systems to determine the regulatory mechanisms underlying splenomegaly. PMID- 29191735 TI - First trimester serum afamin concentrations are associated with the development of pre-eclampsia and gestational diabetes mellitus in pregnant women. AB - OBJECTIVE: Aim of this study was to assess the prognostic capability of afamin to predict pregnancy complications. METHOD: First-trimester screening was consecutively performed in 4948 pregnant women, of whom 474 women developed pregnancy complications [gestational hypertension (n=84), pre-eclampsia (n=30), intrauterine growth restriction (n=107), preterm birth (n=44), and gestational diabetes mellitus (n=209)]. To each woman with pregnancy complications an uncomplicated pregnancy was matched for body mass index. Afamin serum concentrations were measured in 948 pregnant women at the first-trimester screening. RESULTS: Median afamin concentrations were significantly higher in women developing pre-eclampsia or gestational diabetes mellitus when compared to women with uncomplicated pregnancies (76mg/L vs. 65mg/L, p=0.001 and 80mg/L vs. 69mg/L, p<0.001). There was no difference in median afamin values between all other pregnancy complications and their matched controls. Increased afamin (i.e. >65mg/L) was a strong and independent predictor for the development of pre eclampsia (risk ratio, 24.58; 95%CI, 2.82-214.12; p=0.004) as well as gestational diabetes mellitus (risk ratio, 2.07; 95%CI, 1.33-3.22; p=0.001). CONCLUSION: In this large nested case-control study increased afamin concentrations were a strong and independent predictor for pre-eclampsia and gestational diabetes mellitus, suggesting a potential role of afamin as predictive marker for pregnancy-related metabolic disorders. PMID- 29191736 TI - Immunogenicity of Vibrio cholerae outer membrane vesicles secreted at various environmental conditions. AB - Cholera is caused by toxigenic Vibrio cholerae. It is a significant health problem and an important cause of mortality of children in developing countries. Annually, about 5-7 million people are being infected worldwide, leading to death of 100,000 to 120,000. Immunization using the currently available cholera vaccines has been recommended by World Health Organization (WHO) in areas where cholera is endemic or at risk of outbreaks. Gram-negative bacteria secrete outer membrane vesicles (OMVs) that play important roles in virulence and host-pathogen interaction. The content of protein and lipid in OMVs are affected by purification methods and bacterial growth condition. OMVs released from V. cholerae are an appropriate candidate for vaccine development. The protection conferred by a new vaccine candidate prepared using different methods and in two different growth conditions with nanoparticles in an experimental model of cholera in mice was investigated. OMVs were encapsulated in chitosan tripolyphosphate (TPP) nanoparticles prepared by an ionic gelation method and coated with Eudragit as an enteric polymer. OMVs loaded into nanoparticles (NP OMVs) were homogeneous and spherical in shape, with a size of 417nm. BALB/c mice (male, 20-24g) were immunized via intraperitoneal (10ug) or oral route (50ug) with free or encapsulated OMVs. Seventy-eight days after first administration, serum of mice was infected with infection dose of V. cholerae (>=107 CFU). The new vaccine was able to protect fully against infection when it was administered via mucosa. By intraperitoneal route, the unpolymerized OMVs increased the protection against these bacteria.

AB - Although tRNAs participate in the essential function of protein translation in the cytoplasm, tRNA transcription and numerous processing steps occur in the nucleus. This subcellular separation between tRNA biogenesis and function requires that tRNAs be efficiently delivered to the cytoplasm in a step termed "primary tRNA nuclear export". Surprisingly, tRNA nuclear-cytoplasmic traffic is not unidirectional, but, rather, movement is bidirectional. Cytoplasmic tRNAs are imported back to the nucleus by the "tRNA retrograde nuclear import" step which is conserved from budding yeast to vertebrate cells and has been hijacked by viruses, such as HIV, for nuclear import of the viral reverse transcription complex in human cells. Under appropriate environmental conditions cytoplasmic tRNAs that have been imported into the nucleus return to the cytoplasm via the 3rd nuclear-cytoplasmic shuttling step termed "tRNA nuclear re-export", that again is conserved from budding yeast to vertebrate cells. We describe the 3 steps of tRNA nuclear-cytoplasmic movements and their regulation. There are multiple tRNA nuclear export and import pathways. The different tRNA nuclear exporters appear to possess substrate specificity leading to the tantalizing possibility that the cellular proteome may be regulated at the level of tRNA nuclear export. Moreover, in some organisms, such as budding yeast, the pre-tRNA splicing heterotetrameric endonuclease (SEN), which removes introns from pre tRNAs, resides on the cytoplasmic surface of the mitochondria. Therefore, we also describe the localization of the SEN complex to mitochondria and splicing of pre tRNA on mitochondria, which occurs prior to the participation of tRNAs in protein translation.

AB - BACKGROUND: Obesity is a risk factor for increased morbidity and mortality associated with many vaccine preventable infectious diseases such as influenza. Moreover, higher volume of passive rabies immunoglobulin (RIG) due to weight based dosing might suppress vaccine-induced immune responses in obese patients. This study aimed to evaluate the effect of obesity on humoral immune responses to combined equine RIG and rabies vaccine treatment among patients with WHO category III exposure to a rabies suspected animal. METHODS: A single centre, prospective, open-labelled study among WHO category III rabies exposed patients was conducted to compare serum rabies virus neutralizing antibody (RVNA) responses measured by rapid fluorescent focus inhibition test between obese (body mass index, BMI > 30 kg/m2) and control (BMI < 25 kg/m2) patients after combined immunization with equine rabies immunoglobulin and purified chick-embryo cell rabies vaccine for post exposure prophylaxis treatment. RESULTS: Post-vaccination geometric mean titer (GMT) of RVNA concentrations between two groups at day 7 were 0.33 (95% CI: 0.23, 0.46) vs 0.39 (95% CI: 0.27, 0.55), 4.61 (95% CI: 3.20, 6.63) vs 3.78 (95% CI: 2.77, 5.16) at day 14, and 7.45 (95% CI: 5.86, 9.49) vs 5.93 (95%CI: 4.46 7.90) at day 28 for obese and control patients, respectively. There was no statistically significant difference of RVNA GMT between two groups. Seroconversion to at least adequate concentration (RVNA titer >=0.5 IU/mL) rates were 34% at day 7 and 100% at days 14 and 28 in both groups. There were no immediate hypersensitivity reaction and no serious adverse events observed during the study period. CONCLUSIONS: There was no evidence of immunosuppression of antibodies' responses in obese patients. Combined ERIG and rabies virus vaccination for post exposure treatment is safe. PMID- 29191738 TI - Efficacy and safety of simultaneous vaccination with two modified live virus vaccines against porcine reproductive and respiratory syndrome virus types 1 and 2 in pigs. AB - The objective of the study was to compare responses of pigs vaccinated with a PRRS MLV vaccine against PRRSV-1 or PRRSV-2 with the responses of pigs vaccinated simultaneously with both vaccines. Furthermore, the efficacy of the two PRRSV MLV vaccination strategies was assessed following challenge. The experimental design included four groups of 4-weeks old SPF-pigs. On day 0 (DPV0), groups 1-3 (N=18 per group) were vaccinated with modified live virus vaccines (MLV) containing PRRSV-1 virus (VAC-T1), PRRSV-2 virus (VAC-T2) or both (VAC-T1T2). One group was left unvaccinated (N=12). On DPV 62, the pigs from groups 1-4 were mingled in new groups and challenged (DPC 0) with PRRSV-1, subtype 1, PRRSV-1, subtype 2 or PRRSV-2. On DPC 13/14 all pigs were necropsied. Samples were collected after vaccination and challenge. PRRSV was detected in all vaccinated pigs and the majority of the pigs were positive until DPV 28, but few of the pigs were still viremic 62 days after vaccination. Virus was detected in nasal swabs until DPV 7 14. No overt clinical signs were observed after challenge. PRRSV-2 vaccination resulted in a clear reduction in viral load in serum after PRRSV-2 challenge, whereas there was limited effect on the viral load in serum following challenge with the PRRSV-1 strains. Vaccination against PRRSV-1 had less impact on viremia following challenge. The protective effects of simultaneous vaccination with PRRSV Type 1 and 2 MLV vaccines and single PRRS MLV vaccination were comparable. None of the vaccines decreased the viral load in the lungs at necropsy. In conclusion, simultaneous vaccination with MLV vaccines containing PRRSV-1 and PRRSV-2 elicited responses comparable to single vaccination and the commercial PRRSV vaccines protected only partially against challenge with heterologous strains. Thus, simultaneous administration of the two vaccines is an option in herds with both PRRSV types. PMID- 29191739 TI - Addition of C3d-P28 adjuvant to a rabies DNA vaccine encoding the G5 linear epitope enhances the humoral immune response and confers protection. AB - Rabies DNA vaccines based on full-length glycoprotein (G) induce virus neutralizing antibody (VNA) responses and protect against the virus challenge. Although conformational epitopes of G are the main target of VNAs, some studies have shown that a polypeptide linear epitope G5 is also able to induce VNAs. However, a G5 DNA vaccine has not been explored. While multiple doses of DNA vaccines are required in order to confer a protective immune response, this could be overcome by the inclusion of C3d-P28, a molecular adjuvant is know to improve the antibody response in several anti-viral vaccine models. To induce and enhance the immune response against rabies in mice, we evaluated two DNA vaccines based on the linear epitope G5 of Rabies Virus (RABV) glycoprotein (pVaxG5 vaccine) and another vaccine consisting of G5 fused to the molecular adjuvant C3d-P28 (pVaxF1 vaccine). VNA responses were measured in mice immunized with both vaccines. The VNA levels from the group immunized with pVaxG5 decreased gradually, while those from the group vaccinated with pVaxF1 remained high throughout the experimental study. After challenge with 22 LD50 of the Challenge Virus Strain (CVS), the survival rate of mice immunized with pVaxG5 and pVaxF1 was increased by 27% and 50% respectively, in comparison to the PBS group. Furthermore, the in vitro proliferation of anti-rabies specific spleen CD4+ and CD8+ T cells from mice immunized with pVaxF1 was observed. Collectively, these results suggest that the linear G5 epitope is a potential candidate vaccine. Furthermore, the addition of a C3d-P28 adjuvant contributed to enhanced protection, the sustained production of VNAs, and a specific T-cell proliferative response. PMID- 29191740 TI - Influence of Prior Nicotine and Alcohol Use on Functional Outcome in Patients after Intracerebral Hemorrhage. AB - BACKGROUND: The influence of prior nicotine or alcohol use (legal drug use [LDU]) on outcome measures after intracerebral hemorrhage (ICH) is insufficiently established. We investigated drug-specific associations with (1) neuroradiologic and clinical parameters and (2) functional long-term outcome after ICH. METHODS: This observational cohort study analyzed consecutive spontaneous patients with ICH (n = 554) from our prospective institutional registry over a 5-year study period (January 2010 to December 2014). We compared no-LDU patients with LDU patients, and patients using only nicotine, only alcohol, or both. To account for baseline imbalances, we reanalyzed cohorts after propensity score matching. RESULTS: Prevalence of prior LDU was 197 of 554 (35.6%), comprising 94 of 554 (17.0%) with only nicotine use, 33 of 554 (6.0%) with only alcohol use, and 70 of 554 (12.6%) with alcohol and nicotine use. LDU patients were younger (65 [56-73] versus 75 [67-82], P <.01), less often female (n = 61 of 197 [31.0%] versus n = 188 of 357 [52.7%], P <.01), had more often prior myocardial infarction (n = 29 of 197 [14.7%] versus n = 24 of 357 [6.7%], P <.01), and in-hospital complications (sepsis or systemic inflammatory response syndrome: n = 95 of 197 [48.2%] versus n = 98 of 357 [27.5%], P <.01; pneumonia: n = 89 of 197 [45.2%] versus n = 110 of 357 [30.8%], P <.01). Except for an increased risk of pneumonia (odds ratio 2.22, confidence interval [1.04-4.75], P = .04) in patients using both nicotine and alcohol, we detected no significant differences upon reanalysis after propensity score matching of neuroradiologic or clinical parameters, complications, or long-term outcome between patients with and without LDU (mortality: n = 48 of 150 [32.0%] versus n = 45 of 150 [30.0%], P = .71; favorable outcome [modified Rankin Scale 0-3]: n = 56 of 150 [37.3%] versus n = 53 of 150 [35.3%], P = .72). CONCLUSIONS: Prior nicotine use, alcohol use, and their combination were associated with significant differences in baseline characteristics. However, adjusting for unevenly balanced baseline parameters revealed no differences in functional long-term outcome after ICH. PMID- 29191741 TI - Thrombolytic Therapy of Acute Ischemic Stroke during Early Pregnancy. AB - Thrombolytic treatment (recombinant tissue plasminogen activator [rt-PA]) has established efficacy in acute ischemic stroke, but pregnancy has been an exclusion criterion for all clinical trials that validated alteplase in acute stroke, so our knowledge about its use in this condition is limited. Herein we report the successful use of intravenous rt-PA thrombolysis, uncomplicated by neither hemorrhage development nor other complication in a woman who was 13 weeks pregnant with acute ischemic stroke. The brain magnetic resonance imaging diffusion-weighted sequences showed increased signal in the territory of the left middle cerebral artery. Our case had a good maternal and fetal outcome, and advocates that the use of thrombolytics may be feasible in pregnant patients and help to avoid residual neurologic deficits. A summary of published cases in the early aspect of pregnancy and outcomes is presented. Risks and benefits to mother and fetus must be weighted up, but intravenous thrombolysis must not be considered as an absolute contraindication, even in early pregnancy.

PMID- 29191744 TI - Predicting fruit and vegetable consumption in long-haul heavy goods vehicle drivers: Application of a multi-theory, dual-phase model and the contribution of past behaviour. AB - Fruit and vegetable intake is insufficient in industrialized nations and long haul heavy goods vehicle (HGV) drivers are considered a particularly at-risk group. The aim of the current study was to test the effectiveness of a multi theory, dual-phase model to predict fruit and vegetable consumption in Australian long-haul HGV drivers. A secondary aim was to examine the effect of past fruit and vegetable consumption on model paths. A prospective design with two waves of data collection spaced one week apart was adopted. Long-haul HGV drivers (N = 212) completed an initial survey containing theory-based measures of motivation (autonomous motivation, intention), social cognition (attitudes, subjective norms, perceived behavioural control), and volition (action planning, coping planning) for fruit and vegetable consumption. One week later, participants (n = 84) completed a self-report measure of fruit and vegetable intake over the previous week. A structural equation model revealed that autonomous motivation predicted intentions, mediated through attitudes and perceived behavioural control. It further revealed that perceived behavioural control, action planning, and intentions predicted fruit and vegetable intake, whereby the intention behaviour relationship was moderated by coping planning. Inclusion of past behaviour attenuated the effects of these variables. The model identified the relative contribution of motivation, social cognition, and volitional components in predicting fruit and vegetable intake of HGV drivers. Consistent with previous research, inclusion of past fruit and vegetable consumption led to an attenuation of model effects, particularly the intention-behaviour relationship. Further investigation is needed to determine which elements of past behaviour exert most influence on future action. PMID- 29191745 TI - Do nutrition labels influence healthier food choices? Analysis of label viewing behaviour and subsequent food purchases in a labelling intervention trial. AB - BACKGROUND: There are few objective data on how nutrition labels are used in real world shopping situations, or how they affect dietary choices and patterns. DESIGN: The Starlight study was a four-week randomised, controlled trial of the effects of three different types of nutrition labels on consumer food purchases: Traffic Light Labels, Health Star Rating labels, or Nutrition Information Panels (control). Smartphone technology allowed participants to scan barcodes of packaged foods and receive randomly allocated labels on their phone screen, and to record their food purchases. The study app therefore provided objectively recorded data on label viewing behaviour and food purchases over a four-week period. A post-hoc analysis of trial data was undertaken to assess frequency of label use, label use by food group, and association between label use and the healthiness of packaged food products purchased. RESULTS: Over the four-week intervention, study participants (n = 1255) viewed nutrition labels for and/or purchased 66,915 barcoded packaged products. Labels were viewed for 23% of all purchased products, with decreasing frequency over time. Shoppers were most likely to view labels for convenience foods, cereals, snack foods, bread and bakery products, and oils. They were least likely to view labels for sugar and honey products, eggs, fish, fruit and vegetables, and meat. Products for which participants viewed the label and subsequently purchased the product during the same shopping episode were significantly healthier than products where labels were viewed but the product was not subsequently purchased: mean difference in nutrient profile score -0.90 (95% CI -1.54 to -0.26). CONCLUSIONS: In a secondary analysis of a nutrition labelling intervention trial, there was a significant association between label use and the healthiness of products purchased. Nutrition label use may therefore lead to healthier food purchases. PMID- 29191746 TI - Proteomics analysis to understand the ABA stimulation of wound suberization in kiwifruit. AB - : Quick suberin-based healing after wounding played a protective role for plant to prevent further damage. In this study, the stimulative effect of exogenous abscisic acid (ABA) on wound suberization in postharvest kiwifruit was evaluated through suberin staining with toluidine blue O as well as the determination of suberin phenolics and aliphatics in wound tissue. Furthermore, to reveal the regulatory involvement of ABA in wound suberization, comparative quantitative proteomics and transcriptomics analyses based on iTRAQ and qRT-PCR technique were performed. In proteomics levels, a total of 95 protein species consistently showed differential abundance between ABA and control, including 29 down regulated and 66 up-regulated protein species. The Kyoto Encyclopedia of Genes and Genomes (KEGG) with protein-protein interaction analyses revealed that ABA mainly affected the antioxidant system, phenylpropanoid metabolism and lipid metabolism associated with wound suberization. Based on the data of proteomics analysis, the differential expressions of genes encoding 11 selected protein species were confirmed by qRT-PCR analyses. GSH-Px, MDHAR, SOD, APX, POD, PAL, CCR, PPO, CYP86B1, DGGT and KCS11 were likely to be the key enzymes that involved the response of ABA to stimulate wound suberization by mediating the antioxidant system, phenylpropanoid metabolism and lipid metabolism. BIOLOGICAL SIGNIFICANCE: Kiwifruit is susceptible to physical injury causing postharvest deterioration during harvest, transportation and storage. Therefore, quick healing is important for maintaining the postharvest quality of injured fruit. This work elucidated the potential role of ABA and the proteomic mechanism of its regulation in wound suberization of postharvest kiwifruit. PMID- 29191747 TI - Peptide fingerprinting of the sea anemone Heteractis magnifica mucus revealed neurotoxins, Kunitz-type proteinase inhibitors and a new beta-defensin alpha amylase inhibitor. AB - : Sea anemone mucus, due to its multiple and vital functions, is a valuable substance for investigation of new biologically active peptides. In this work, compounds of Heteractis magnifica mucus were separated by multistage liquid chromatography and resulting fractions were analyzed by MALDI-TOF MS. Peptide maps constructed according to the molecular masses and hydrophobicity showed presence of 326 both new and known peptides. Several major peptides from mucus were identified, including the sodium channel toxin RpII isolated earlier from H. magnifica, and four Kunitz-type proteinase inhibitors identical to H. crispa ones. Kunitz-type transcript diversity was studied and sequences of mature peptides were deduced. New beta-defensin alpha-amylase inhibitor, a homolog of helianthamide from Stichodactyla helianthus, was isolated and structurally characterized. Overall, H. magnifica is a source of biologically active peptides with great pharmacological potential. BIOLOGICAL SIGNIFICANCE: Proteinase and alpha-amylase inhibitors along with toxins are major components of H. magnifica mucus which play an important role in the successful existence of sea anemones. Obtained peptide maps create a basis for more accurate identification of peptides during future transcriptomic/genomic studies of sea anemone H. magnifica. PMID- 29191748 TI - Study of a novel agent for TCA precipitated proteins washing - comprehensive insights into the role of ethanol/HCl on molten globule state by multi spectroscopic analyses. AB - : Sample preparation for mass spectrometry-based proteomics is a key step for ensuring reliable data. In gel-free experimental workflows, protein purification often starts with a precipitation stage using trichloroacetic acid (TCA). In presence of TCA, proteins precipitate in a stable molten globule state making the pellet difficult to solubilize in aqueous buffer for proteolytic digestion and MS analysis. In this context, the objective of this work was to study the suitability of a novel agent, ethanol/HCl, for the washing of TCA-precipitated proteins. This method optimized the recovery of proteins in aqueous buffer (50 to 96%) while current organic solvents led to losses of material. Following a mechanistic study, the effect of ethanol/HCl on the conformation of TCA precipitated proteins was investigated. It was shown that the reagent triggered the unfolding of TCA-stabilized molten globule into a reversible intermediate, characterized by a specific Raman signature, which favored protein subsequent resolubilization. Finally, the efficiency of ethanol/HCl for the washing of TCA precipitated proteins extracted from a biofilm, a soil or a mouse liver was demonstrated (data available via ProteomeXchange with identifier PXD008110). Being versatile and simple, it could be of great interest to include an ethanol/HCl wash-step to produce high-quality protein extracts. SIGNIFICANCE: In mass spectrometry-based proteomics workflows, proteins precipitation and/or washing usually involves the use of acetone. In fact, this solvent is effective for removing both biological interferences (e.g. lipids) and chemicals employed in protein extraction/purification protocols (e.g. TCA, SDS). However, the use of acetone can lead to significant protein losses. Moreover, when proteins are precipitated with TCA, the acetone-treated precipitate remains hard to disperse, leading to poor resolubilization of proteins in aqueous buffers. Here, we investigated the use of ethanol/HCl for washing TCA-precipitated proteins, with the aim to produce high-quality protein extracts which can be directly analyzed by LC-MS. An opening study on standard solutions showed that ethanol/HCl led to reduced losses of proteins compared to usual solvents (i.e. acetone and ethanol). This reagent also enabled a better solubilization of proteins in aqueous buffer that is necessary for their direct trypsin digestion and LC-HRMS analysis. A mechanistic study, performed through several spectroscopic analyses (LC-HRMS, Raman, spectrofluorometry), showed that treatment with ethanol/HCl induced conformational changes of TCA-precipitated proteins. Finally, we compared the efficiency of ethanol/HCl to published protocols for the washing of protein extracts from three different complex samples (i.e. soil, biofilm, and mouse liver). Our results demonstrated that ethanol/HCl is a valuable alternative to previous protein washing methods and, therefore could become a useful tool in mass spectrometry-based proteomics workflows for various applications (e.g. clinical research, chemical biology, environmental metaproteomics...). PMID- 29191749 TI - Design and verification of halogen-bonding system at the complex interface of human fertilization-related MUP PDZ5 domain with CAMK's C-terminal peptide. AB - Calmodulin-dependent protein kinase (CAMK) is physiologically activated in fertilized human oocytes and is involved in the Ca2+ response pathways that link the fertilization calmodulin signal to meiosis resumption and cortical granule exocytosis. The kinase has an unstructured C-terminal tail that can be recognized and bound by the PDZ5 domain of its cognate partner, the multi-PDZ domain protein (MUP). In the current study, we reported a rational biomolecular design of halogen-bonding system at the complex interface of CAMK's C-terminal peptide with MUP PDZ5 domain by using high-level computational approaches. Four organic halogens were employed as atom probes to explore the structural geometry and energetic property of designed halogen bonds in the PDZ5-peptide complex. It was found that the heavier halogen elements such as bromine Br and iodine I can confer stronger halogen bond but would cause bad atomic contacts and overlaps at the complex interface, while fluorine F cannot form effective halogen bond in the complex. In addition, the halogen substitution at different positions of peptide's aromatic ring would result in distinct effects on the halogen-bonding system. The computational findings were then verified by using fluorescence analysis; it is indicated that the halogen type and substitution position play critical role in the interaction strength of halogen bonds, and thus the PDZ5 peptide binding affinity can be improved considerably by optimizing their combination. PMID- 29191750 TI - Sucrose withdrawal induces depression and anxiety-like behavior by Kir2.1 upregulation in the nucleus accumbens. AB - Dieting induces depression and anxiety among other emotional symptoms. Animal models indicate that repeated access to palatable foods such as sugar induces depression and anxiety-like behavior when the food is no longer available. However, the neurobiological mechanisms of how dietary restriction influences mood have not been fully understood. We used the two-bottle sucrose choice paradigm as an overeating and withdrawal model. Withdrawal after lengthy sucrose overeating elicited depression and anxiety-like behavior, which was reversed by sucrose reinstatement. In the nucleus accumbens (NAc) of sucrose withdrawal animals, dopamine levels and cAMP response element binding protein (CREB) activity were significantly reduced, while the inwardly rectifying K+ channel, Kir2.1, was significantly elevated. In addition, overexpression of Kir2.1 selectively in neurons expressing dopamine D1 receptors was sufficient to induce negative mood-linked behavior in the absence of sucrose overeating experience. As elevated K+ channels reduce neuronal excitability, a sucrose withdrawal-induced increase in Kir2.1 expression is able to decrease NAc activity, which provides a cellular basis for depression and anxiety-like behavior in animals. PMID- 29191752 TI - The use of chemogenetic approaches to study the physiological roles of muscarinic acetylcholine receptors in the central nervous system. AB - Chemical genetic has played an important role in linking specific G protein coupled receptor (GPCR) signalling to cellular processes involved in central nervous system (CNS) functions. Key to this approach has been the modification of receptor properties such that receptors no longer respond to endogenous ligands but rather can be activated selectively by synthetic ligands. Such modified receptors have been called Receptors Activated Solely by Synthetic Ligands (RASSLs) or Designer Receptors Exclusively Activated by Designer Drugs (DREADDs). Unlike knock-out animal models which allow detection of phenotypic changes caused by loss of receptor functions, RASSL and DREADD receptors offer the possibility of rescuing "knock-out" phenotypic deficits by administration of the synthetic ligands. Here we describe the use of these modified receptors in defining the physiological role of GPCRs and validation of receptors as drug targets. This article is part of the Special Issue entitled 'Neuropharmacology on Muscarinic Receptors'. PMID- 29191751 TI - Hippocampus ghrelin receptor signaling promotes socially-mediated learned food preference. AB - Social cues are potent regulators of feeding behavior, yet the neurobiological mechanisms through which social cues influence food intake are poorly understood. Here we investigate the hypothesis that the appetite-promoting gut-derived hormone, ghrelin, signals in the hippocampus to promote learned social aspects of feeding behavior. We utilized a procedure known as 'social transmission of food preference' (STFP) in which rats ('Observers') experience a social interaction with another rat ('Demonstrators') that recently consumed flavored/scented chow. STFP learning in Observer rats is indicated by a significant preference for the Demonstrator paired flavor of chow vs. a novel unpaired flavor of chow in a subsequent consumption choice test. Our results show that relative to vehicle treatment, ghrelin targeted to the ventral CA1 subregion of the hippocampus (vHP) enhanced STFP learning in rats. Additionally, STFP was impaired following peripheral injections of l-cysteine that reduce circulating ghrelin levels, suggesting that vHP ghrelin-mediated effects on STFP require peripheral ghrelin release. Finally, the endogenous relevance of vHP ghrelin receptor (GHSR-1A) signaling in STFP is supported by our data showing that STFP learning was eliminated following targeted viral vector RNA interference-mediated knockdown of vHP GHSR-1A mRNA. Control experiments indicate that vHP ghrelin-mediated STFP effects are not secondary to altered social exploration and food intake, nor to altered food preference learning based on nonsocial olfactory cues. Overall these data reveal a novel neurobiological system that promotes conditioned, social aspects of feeding behavior. PMID- 29191753 TI - Melanin-Concentrating Hormone acts through hypothalamic kappa opioid system and p70S6K to stimulate acute food intake. AB - Melanin-Concentrating Hormone (MCH) is one of the most relevant orexigenic factors specifically located in the lateral hypothalamic area (LHA), with its physiological relevance demonstrated in studies using several genetically manipulated mice models. However, the central mechanisms controlling MCH-induced hyperphagia remain largely uncharacterized. Here, we show that central injection of MCH in mice deficient for kappa opoid receptor (k-OR) failed to stimulate feeding. To determine the hypothalamic area responsible for this MCH/k-OR interaction, we performed virogenetic studies and found that downregulation of k OR by adeno-associated viruses (shOprk1-AAV) in LHA, but not in other hypothalamic nuclei, was sufficient to block MCH-induced food intake. Next, we sought to investigate the molecular signaling pathway within the LHA that mediates acute central MCH stimulation of food intake. We found that MCH activates k-OR and that increased levels of phosphorylated extracellular signal regulated kinase (ERK) are associated with downregulation of phospho-S6 Ribosomal Protein. This effect was prevented when a pharmacological inhibitor of k-OR was co-administered with MCH. Finally, the specific activation of the direct upstream regulator of S6 (p70S6K) in the LHA attenuated MCH-stimulated food consumption. Our results reveal that lateral hypothalamic k-OR system modulates the orexigenic action of MCH via the p70S6K/S6 pathway. PMID- 29191754 TI - Disease-modifying benefit of Fyn blockade persists after washout in mouse Alzheimer's model. AB - Alzheimer's disease remains without a disease-modifying therapy that improves symptoms after therapy withdrawal. Because no investigational agents have demonstrated disease-modifying effects clinically, we tested whether the Fyn inhibitor, saracatinib, provides persistent improvement in a transgenic model. Aged APPswe/PS1DeltaE9 mice were treated with saracatinib or memantine for 4 weeks and spatial memory improved to control levels. After drug washout, there was sustained rescue of both memory function and synapse density by saracatinib, but a loss of benefit from memantine. These data demonstrate a disease-modifying persistent benefit for saracatinib in a preclinincal Alzheimer's model, and distinguish its action from that of memantine. PMID- 29191756 TI - Functional connectivity between anterior cingulate cortex and orbitofrontal cortex during value-based decision making. AB - There is a growing body of evidence showing that the anterior cingulate (ACC) and the orbitofrontal (OFC) cortex are both essential for reinforcement-guided decision making. Focusing on functional connectivity approach through coherence, we studied whether communication between the ACC and OFC through neural synchronization is a necessary stage for performing value-based decision making. We used a T-maze task with a differential reward (Large vs. small reward) and cost (long vs. short waiting time) and simultaneously recorded local field potentials (LFP) from the ACC and OFC. Task-dependent synchronization in theta/low beta (4-20 Hz) frequency bands were observed between areas when rats chose the higher over the lower reward. This synchronization was significantly poorer when rats chose lower rewards or passively performed the task. High-gamma (80-100 Hz) synchrony between areas was also observed, however, it was not dependent on the animal's decision. Our results propose that synchronization between the ACC and OFC in the low-frequency range is necessary during value based decision making. PMID- 29191755 TI - Pharmacological validation of voluntary gait and mechanical sensitivity assays associated with inflammatory and neuropathic pain in mice. AB - The urgent need for more effective analgesic treatment options has prompted a re evaluation of the behavioral tests used to assess pain in pre-clinical research, with an emphasis on inclusion of more voluntary, un-evoked behavioral assessments of pain. In order to validate voluntary gait analysis and a voluntary mechanical conflict-avoidance assay, we tested mouse models of neuropathy (spared nerve injury) and inflammation (complete Freund's adjuvant) alongside reflexive measures of mechanical and thermal hypersensitivity. To establish whether the observed changes in behavioral responses were pain-related, known analgesics (buprenorphine, gabapentin, carprofen) were also administered. Spared nerve injury persistently altered several gait indices, whereas complete Freund's adjuvant caused only transient changes. Furthermore, known analgesics could not reverse these gait changes, despite demonstrating their previously established efficacy in reflexive measures of mechanical and thermal hypersensitivity. In contrast, the mechanical conflict-avoidance assay demonstrated aversion in mice with neuropathy and inflammation-induced hypersensitivity, which could both be reversed by analgesics. We conclude that voluntary gait changes in rodent neuropathic and inflammatory pain models are not necessarily indicative of pain related adaptations. On the other hand, mechanical conflict-avoidance represents a valid operant assay for quantifying pain-related behaviors in mice that can be reversed by known analgesics. PMID- 29191757 TI - Does Previous Laparoscopic Experience Influence Basic Robotic Surgical Skills? AB - OBJECTIVE: Studies addressing the effect of laparoscopic experience on robotic skills have produced conflicting results. This study aimed to compare simulated robotic surgical tasks using the virtual reality simulator dV-Trainer between laparoscopically experienced surgeons and first-year surgical residents. DESIGN: A cross-sectional study. Participants completed 4 trials of the following tasks on the dV-Trainer: Peg Board 2, Ring and Rail 1, and Suture Sponge 1. Performance was recorded using a computerized built-in scoring algorithm. Scores and metrics were compared between groups 1 and 2 and between the first and subsequent trials. SETTING: Hospital de Clinicas, Porto Alegre, Brazil, a tertiary care teaching hospital. PARTICIPANTS: Twenty laparoscopically experienced surgeons (group 1) and 20 first-year surgical residents (group 2). All participants completed the study. RESULTS: The overall scores for Peg Board 2 (738.04 +/- 267.83 vs 730.39 +/- 225.31; p = 0.57), Ring and Rail 1 (919.03 +/- 242.69 vs 965.84 +/- 222.96; p = 0.13), and Suture Sponge 1 (563.62 +/- 185.50 vs 560.99 +/- 152.71; p = 0.67) did not differ significantly between groups 1 and 2. Group 1 had better results for master workspace range in Peg Board 2 and Ring and Rail 1. Group 2 had higher scores for economy of motion in Peg Board 2 and Ring and Rail 1 and for excessive instrument force in Ring and Rail 1. In both groups, the overall scores in the third and fourth trials were significantly higher than those in the first trial. CONCLUSIONS: There are no significant differences in the performance of simulated robotic surgical tasks between laparoscopically experienced surgeons and laparoscopically naive surgical residents. Some slight differences were observed in specific metrics, but these differences were not sufficient to change the final results. We may assume that laparoscopic experience should not be an essential step in the initial learning curve of robotic surgery. PMID- 29191758 TI - The association between experiences with patient-centred care and health-related quality of life in women with endometriosis. AB - In this cross-sectional study, we investigated whether patient-centred endometriosis care (PCEC) is associated with health-related quality of life (HRQOL). Dutch-speaking women with endometriosis, treated by laparoscopy in a university clinic between 2009 and 2010, were eligible (n = 194). Endometriosis Health Profile-30 and ENDOCARE questionnaire were used to assess HRQOL and PCEC, respectively. Overall and subscale scores were converted to a scale from 0 (best score) to 100 (worst score). Linear regression analyses were conducted while controlling for confounders. Participants (n = 109) had a mean age of 35.4 years; 79.6% had moderate-severe endometriosis. Mean scores for overall HRQOL and PCEC were 29.3/100 and 38.0/100, respectively. The PCEC-subscale 'continuity' was significantly associated with overall HRQOL (P = 0.029). A significant association was found between overall PCEC and the HRQOL-subscale 'social support' (P = 0.026). The PCEC-subscales 'information' and 'continuity' were significantly associated with the HRQOL-subscales 'emotional wellbeing' and 'social support' (P < 0.05). The PCEC-subscale 'respect' was significantly associated with the HRQOL-subscale 'emotional wellbeing' (P = 0.023). Multivariable regression analyses produced no significant associations, including all subscales of PCEC. Providing PCEC could lead to better HRQOL, especially if paying attention to 'continuity', 'respect' and 'information'. Large-scale longitudinal research is needed. PMID- 29191759 TI - A novel and versatile dual fluorescent reporter tool for the study of gene expression and regulation in multi- and single copy number. AB - To unravel intricate mechanisms of gene regulation it is imperative to work in physiologically relevant conditions and therefore preferentially in single copy constructs, which are not always easy to manipulate. Such in vivo studies are generally based on enzymatic assays, microarrays, RNA-seq, qRT-PCR, or multicopy reporter gene systems, frequently with beta-galactosidase, luciferase or a fluorescent protein as reporter. Each method has its advantages and shortcomings and may require validation. Enzyme assays are generally reliable but may be quite complex, time consuming, and require a (expensive) substrate. Microarrays and RNA seq provide a genome wide view of gene expression but may rapidly become expensive and time consuming especially for detailed studies with large numbers of mutants, different growth conditions and multiple time points. Multicopy reporter gene systems are handy to generate numerous constructs but may not provide accurate information due to titration effects of trans-acting regulatory elements. Therefore and in spite of the existence of various reporter systems, there is still need for an efficient and user-friendly tool for detailed studies and high throughput screenings. Here we develop and validate a novel and versatile fluorescent reporter tool to study gene regulation in single copy mode that enables real-time measurement. This tool bears two independent fluorescent reporters that allow high throughput screening and standardization, and combines modern efficient cloning methods (multicopy, in vitro manipulation) with classical genetics (in vivo homologous recombination with a stable, self transmissible episome) to generate multi- and single copy reporter systems. We validate the system with constitutive and differentially regulated promoters and show that the tool can equally be used with heterologous transcription factors. The flexibility and versatility of this dual reporter tool in combination with an easy conversion from a multicopy plasmid to a stable, single copy reporter system makes this system unique and attractive for a variety of applications. Examples are in vivo studies of DNA-binding transcription factors (single copy) or screening of promoter and RBS libraries (multicopy) for synthetic biology purposes. PMID- 29191760 TI - Thermodynamic Estimate of the Number of Solvent Molecules Displaced by a Solute Molecule for Enthalpy-Driven Adsorption: Phenobarbital and Activated Carbons as the Model System. AB - A Modified Crisp Equation, describing the differential Gibbs free energy of the adsorption process, is being proposed, which considers multiple sites available on the surface for adsorption and their relative fractions. The differential Gibbs free energy can be calculated by the van't Hoff Equation, which depends on the affinity constant in the Langmuir-like equation. To consider the number of solvent molecules displaced by a solute molecule in the adsorption process, a new derivative of the Langmuir-like equation is being proposed as well. By comparing the differential Gibbs free energies obtained from the 2 thermodynamic relationships, it can be determined that a phenobarbital molecule displaces 5 water molecules on the activated carbon surface for site-specific adsorption from solution. For the series of experimental conditions studied, including 4 activated carbons, pH effects, temperature effects, and solvent effects, the corrected differential Gibbs free energies using n1 = 5 for site-specific adsorption are quite consistent between the 2 thermodynamic relationships. The difference between the estimates of the differential Gibbs free energies by the Modified Crisp Equation and the van't Hoff Equation provides a new experimental method to calculate the number of solvent molecules displaced by an adsorbing solute molecule. PMID- 29191761 TI - DSM-5 personality trait domains and withdrawal versus approach motivational tendencies in response to the perception of other people's desperation and angry aggression. AB - Expressions of affect communicate social messages, which trigger approach and withdrawal/avoidance motivational tendencies in the observer. The present study investigated relationships between inter-individual differences in the motivational responses to other people's affect expressions and DSM-5 personality trait domains. State-dependent, transient EEG alpha asymmetry responses provided indicators of the relative activation of withdrawal versus approach motivation in the respective social-emotional contexts. The Personality Inventory for the DSM-5 (PID-5) was used for the assessment of personality traits in a non-clinical sample. Individuals with higher levels of Antagonism showed relative activation of approach versus withdrawal motivation (as indicated by less relative right frontal activation) in response to confrontation with auditory expressions of angry aggression, whereas participants with higher levels of Detachment showed relative activation of withdrawal versus approach motivation (as indicated by greater relative right frontal activation) to the perception of other people's desperate crying. PMID- 29191762 TI - APRN-Conducted Medication Reviews for Long-Stay Nursing Home Residents. AB - OBJECTIVE: As part of the Missouri Quality Initiative (MOQI) to reduce hospitalizations for long-stay nursing home residents, this article describes reasons MOQI advanced practice registered nurses (APRNs) recommended medication order changes as part of their medication review process as well as the outcomes of their recommendations. DESIGN: Cross-sectional descriptive study of MOQI APRN conducted medication reviews. SETTING: Long-stay nursing homes participating in the MOQI project. PARTICIPANTS: Seventeen MOQI APRNs recorded medication reviews for 3314 long-stay residents residing in 16 Midwestern nursing homes over a 2 year period. INTERVENTION: APRNs conducted medication reviews and made recommendations for medication order changes to residents' medical providers. MEASUREMENTS: The MOQI medication review database was used to abstract data. RESULTS: There were 19,629 medication reviews recorded for 3314 residents during the 2-year period. Of the 19,629 reviews, 50% (n = 9841) resulted in recommended order changes of which 82% (n = 8037) of order changes occurred. More than two thirds of recommendations were because of changes in the residents' plans of care. Other recommendations included adjusting and/or discontinuing medications that had the potential for harm. CONCLUSION: Resident care needs are dynamic, resulting in the need for frequent medication order changes. MOQI APRNs, because of their advanced pharmacological education and daily presence in the nursing home, are uniquely positioned to ensure residents' medications aligned with their overall goals of care while minimizing risk of harm. PMID- 29191763 TI - Reliability and Validity of the Care Plan Checklist for Evidence of Person Centered Approaches for Behavioral and Psychological Symptoms Associated With Dementia. AB - PURPOSE: The purpose of this study was to test the reliability and validity of the Care Plan Checklist for Evidence of Person-Centered Approaches for Behavioral and Psychological Symptoms Associated with Dementia (BPSD). METHODS: This study used baseline data from the first cohort of a larger randomized clinical trial testing the implementation of the Evidence of Integration Triangle for BPSD. Fourteen settings volunteered to participate, 8 from Maryland and 6 from Pennsylvania, and a total of 137 residents were recruited. In addition to completing the Care Plan Checklist for Evidence of Person-Centered Approaches for BPSD, assessments of depressive symptoms (Cornell Scale for Depression in Dementia), resistiveness to care (Resistiveness to Care Scale), and agitation (Cohen-Mansfield Agitation Inventory) were also completed on each participant. Reliability was tested based on evidence of internal consistency and inter-rater reliability. Construct validity was tested using a Rasch measurement model to determine item fit and hypothesis testing using bivariate correlations. Item mapping was also performed. RESULTS: The majority of the sample was female (69%), Caucasian (69%), non-Hispanic (98%), and not married (78%). The mean age of the sample was 82.01 years (standard deviation = 11.44). There was evidence of reliability based on internal consistency with a Cronbach alpha of 0.96 and inter rater reliability with correlations between 2 evaluators of r = 0.93, P = .001. There was evidence of validity of the scale based on item fit as the infit statistics and outfit statistics were all within the acceptable range with the exception of the outfit statistic for the item focused on sexually inappropriate behaviors. Lastly, there was evidence of significant relationships between the Care Plan Checklist for Evidence of Person-Centered Approaches for BPSD and the Cornell Scale for Depression in Dementia (r = 0.38, P < .001) and the Cohen Mansfield Agitation Inventory (r = 0.44, P < .001). There was not a significant relationship between resistiveness to care and scores on the Care Plan Checklist for Evidence of Person-Centered Approaches for BPSD (r = -0.02, P = .86). There were 78 care plans that were so low in evidence of using appropriate interventions that they could not be differentiated. CONCLUSIONS: There was sufficient evidence for the reliability and validity of the Care Plan Checklist for Evidence of Person-Centered Approaches for BPSD. Additional items should be considered to better differentiate those low on the Checklist for Evidence of Person-Centered Approaches for BPSD. PMID- 29191764 TI - Nursing Home-Hospice Collaboration and End-of-Life Hospitalizations Among Dying Nursing Home Residents. AB - OBJECTIVES: Nursing homes (NHs) collaboration with hospices appears to improve end-of-life (EOL) care among dying NH residents. However, the potential benefits of NH-hospice collaboration may vary with the patterns of this collaboration. This study examines the relationship between the attributes of NH-hospice collaboration, especially the exclusivity of NH-hospice collaboration (ie, the number of hospice providers in a NH), and EOL hospitalizations among dying NH residents. DESIGN: This national retrospective cohort study linked 2000-2009 NH assessments (ie, the Minimum Data Set 2.0) and Medicare data. A linear probability model with facility fixed-effects was estimated to examine the relationship between EOL hospitalization and the attributes of NH-hospice collaborations, adjusting for individual and facility characteristics. We also performed a set of sensitivity analyses, including stratified analyses by volume of hospice services in a NH and stratified analyses by rural vs urban NH locations. SETTINGS: All Medicare and/or Medicaid certified US NHs with at least 8 years of data and at least 30 beds. PARTICIPANTS: NH decedents resided in Medicare and/or Medicaid certified NHs in the US between 2000 and 2009. We restricted the analyses to those continuously enrolled in Medicare fee-for service in the last 6 months of life and those who were in NHs for the last 30 days of life. In total, we identified 2,954,276 NH decedents over the study period. MEASUREMENTS: The outcome variable was measured as dichotomous, indicating whether a dying NH resident was hospitalized in the last 30 days of life. The attributes of NH-hospice collaboration were measured by the volume of hospice services (defined as the ratio of number of hospice days to the total NH days per NH per calendar year) and the number of hospice providers in a NH (defined as the number of unique hospice providers in a NH per year). We categorized NHs into groups based on the number of hospice providers (1, 2 or 3, and >=4) in the NH, and conducted sensitivity analysis using a different categorization (1, 2, and 3+ hospice providers). RESULTS: The pattern of NH hospice collaboration changed significantly over years; the average number of hospices in a NH increased from 1.4 in 2000 to 3.2 in 2009. The volume of NH hospice collaboration also increased substantially. The multivariate regression analyses indicated that having more hospice providers in the NH was not associated with lower risks of EOL hospitalizations. After accounting for individual and facility characteristics, increasing hospice providers from 1 to at least 4 was associated with an overall 1 percentage point increase in the likelihood of EOL hospitalizations among dying residents (P < .01), and such relationship remained in NHs with moderate or high volume NHs in the stratified analyses. Stratified analysis by rural vs urban NHs suggested that the relationship between the number of hospice providers and EOL hospitalizations was mainly in urban NHs. CONCLUSIONS: More hospice providers in the NH was not associated with lower EOL hospitalizations, especially among NHs with relatively high volume of hospice services.

PMID- 29191766 TI - JAMDA's New Editors-in-Chief Present a Vision for the Journal of Post-Acute and Long-Term Care Medicine. PMID- 29191767 TI - Capsaicin, the primary constituent of pepper sprays and its pharmacological effects on mammalian ocular tissues. AB - Capsaicin is the principal constituent of oleoresin capsicum, or pepper spray, as it is commonly known. Pepper sprays are frequently used in riot control situations by defence organizations all over the world to deal with uncontrolled civil or criminal disturbances. Although capsaicin is noted for its irritant and inflammatory properties, the ocular profile of capsaicin has not been specifically studied and interpreted. The present review analyses the mammalian opthalmological profile of capsaicin and its pharmacological and toxicological manifestations including capsaicin induced corneal changes, neurogenic inflammation, neuroprotective influences on retinal ganglion cells (RGCs), depletion of neuropeptide content in sensory nerve terminals etc. Substantial views on the capsaicin receptor Transient Receptor Potential Vanilloid V1 (TRPV1), its presence, significance and capsaicin induced mediations have been presented. Studies conducted previously on the reversal of capsaicin evoked ocular responses have been briefly demonstrated. In this regard, TRPV1 antagonists (especially the competitive antagonist Capsazepine) have been indicated as potential candidates in mitigating or alleviating capsaicin elicited ocular responses. The review overall is a comprehensive perspective of the ocular inflammatory and pharmacological responses generated on exposure to capsaicin and concludes suggesting a possible regulatory framework for relief from the same presumably by the employment of specialized and target specific TRPV1 antagonists. PMID- 29191768 TI - Interactions of aliskiren, a direct renin inhibitor, with antiepileptic drugs in the test of maximal electroshock in mice. AB - Experimental studies showed that certain angiotensin-converting enzyme inhibitors and angiotensin AT1 receptor antagonists can decrease seizure severity in rodents. Additionally, some of these blockers of the renin-angiotensin system have been documented to enhance the anticonvulsant activity of antiepileptic drugs against maximal electroshock-induced seizures. The aim of the current study was to investigate the effect of aliskiren, a direct renin inhibitor and a novel antihypertensive drug, on the protective action of numerous antiepileptic drugs (carbamazepine, valproate, clonazepam, phenobarbital, oxcarbazepine, lamotrigine, topiramate and pregabalin) in the test of maximal electroshock in mice. The examined drugs were administered intraperitoneally. Aliskiren up to a dose of 75mg/kg did not affect the threshold for electroconvulsions, however, aliskiren (75mg/kg) enhanced the anticonvulsant action of clonazepam and valproate. Following aliskiren treatment, a higher brain concentration of valproate was noted, suggesting a pharmacokinetic interaction. In the rota-rod test, the concomitant treatment with aliskiren (50 or 75mg/kg) and clonazepam (22.6mg/kg) impaired motor coordination while clonazepam (22.6mg/kg) alone showed strong tendency towards this impairment. The combination of aliskiren (75mg/kg) with phenobarbital (25.5mg/kg) caused long-term memory deficits in the passive avoidance task. This study shows that there are no negative interactions between aliskiren and the examined antiepileptic drugs as concerns their anticonvulsant activity. Aliskiren even potentiated the anticonvulsant action of clonazepam and valproate against maximal electroshock. The impact of aliskiren alone on seizure activity or on the anticonvulsant and adverse activity of antiepileptic drugs needs further evaluation in other animal models of seizures. PMID- 29191769 TI - Berberine protects acute liver failure in mice through inhibiting inflammation and mitochondria-dependent apoptosis. AB - Acute liver failure (ALF) is characterized by sudden large area of inflammation and extensive hepatocyte apoptosis. This study identified the natural product berberine as a potential agent for acute liver failure(ALF). First, in vitro, BBR pre-incubation (5, 10 and 20MUM) alleviated L02 hepatocytes injury induced by D GalN (5mM)/TNF-alpha (100ng/ml). Second, in vivo, BBR pre-treatment attenuated D Galactosamine (D-GalN)/lipopolysaccharide (LPS)-induced acute liver failure, as evidenced by the reduction of mortality, the alleviation of liver pathological changes and the inhibition of alanine aminotransferase (ALT)/aspartate aminotransferase (AST). Our results further illustrated that BBR inhibited the nuclear translocation of NF-kappaB p65 and subsequently suppressed the expressions of inflammatory cytokines, tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) at both mRNA and protein levels in ALF. Moreover, western blotting demonstrated that BBR effectively inhibited apoptosis via reducing cytochrome c release, Bax/Bcl-2 ratio and caspase-3/-9 cleavage in vitro and in vivo. In conclusion, our findings suggest that BBR serves as a potential agent for preventing or treating human ALF by inhibiting inflammation and mitochondria-dependent apoptosis. PMID- 29191770 TI - Auditory-motor coupling affects phonetic encoding. AB - Recent studies have shown that moving in synchrony with auditory stimuli boosts attention allocation and verbal learning. Furthermore rhythmic tones are processed more efficiently than temporally random tones ('timing effect'), and this effect is increased when participants actively synchronize their motor performance with the rhythm of the tones, resulting in auditory-motor synchronization. Here, we investigated whether this applies also to sequences of linguistic stimuli (syllables). We compared temporally irregular syllable sequences with two temporally regular conditions where either the interval between syllable onsets (stimulus onset asynchrony, SOA) or the interval between the syllables' vowel onsets was kept constant. Entrainment to the stimulus presentation frequency (1 Hz) and event-related potentials were assessed in 24 adults who were instructed to detect pre-defined deviant syllables while they either pedaled or sat still on a stationary exercise bike. We found larger 1 Hz entrainment and P300 amplitudes for the SOA presentation during motor activity. Furthermore, the magnitude of the P300 component correlated with the motor variability in the SOA condition and 1 Hz entrainment, while in turn 1 Hz entrainment correlated with auditory-motor synchronization performance. These findings demonstrate that acute auditory-motor coupling facilitates phonetic encoding. PMID- 29191771 TI - Silencing rno-miR-155-5p in rat temporal lobe epilepsy model reduces pathophysiological features and cell apoptosis by activating Sestrin-3. AB - Temporal lobe epilepsy (TLE) is a chronic neurological disease characterized by recurrent spontaneous seizures. MicroRNAs are dysregulated in various pathological conditions including epilepsy. Therefore, we hypothesized that the dysregulation of these microRNAs might also be associated with the pathogenesis of TLE. In this study, we found that a microRNA, hsa-miR-155-5p, was upregulated in patients with TLE post-surgery, and hence associated with clinical and pathological manifestations and seizure outcomes. We then used a rat model of experimental epilepsy induced by pilocarpine and revealed that the rat homologue was upregulated as well. Importantly, injection of an antagomiR of rno-miR-155-5p in vivo resulted in a reduction of the pathophysiological features associated with the status epilepticus, which was accompanied by decrease of apoptosis in the hippocampus. This effect was correlated with an increase in rat Sestrin-3 expression, which was a gene known to counteract oxidative stress. This rescue was also observed after injection of a lentivirus carrying the small interfering RNA of rat Sestrin-3 gene in the hippocampus. In addition, rno-miR-155-5p as well as rat Sestrin-3 mRNA and protein expression were partly dependent on oxidative stress induced by H2O2 in PC12 cells. Taken together, our data suggest that rno miR-155-5p is a potent post-transcriptional regulator of rat Sestrin-3 and it may be one of the molecular links between brain damage and increased risk for seizures during damage by oxidative stress. PMID- 29191772 TI - Gap-induced reductions of evoked potentials in the auditory cortex: A possible objective marker for the presence of tinnitus in animals. AB - Animal models of tinnitus are essential for determining the underlying mechanisms and testing pharmacotherapies. However, there is doubt over the validity of current behavioural methods for detecting tinnitus. Here, we applied a stimulus paradigm widely used in a behavioural test (gap-induced inhibition of the acoustic startle reflex GPIAS) whilst recording from the auditory cortex, and showed neural response changes that mirror those found in the behavioural tests. We implanted guinea pigs (GPs) with electrocorticographic (ECoG) arrays and recorded baseline auditory cortical responses to a startling stimulus. When a gap was inserted in otherwise continuous background noise prior to the startling stimulus, there was a clear reduction in the subsequent evoked response (termed gap-induced reductions in evoked potentials; GIREP), suggestive of a neural analogue of the GPIAS test. We then unilaterally exposed guinea pigs to narrowband noise (left ear; 8-10 kHz; 1 h) at one of two different sound levels - either 105 dB SPL or 120 dB SPL - and recorded the same responses seven-to-ten weeks following the noise exposure. Significant deficits in GIREP were observed for all areas of the auditory cortex (AC) in the 120 dB-exposed GPs, but not in the 105 dB-exposed GPs. These deficits could not simply be accounted for by changes in response amplitudes. Furthermore, in the contralateral (right) caudal AC we observed a significant increase in evoked potential amplitudes across narrowband background frequencies in both 105 dB and 120 dB-exposed GPs. Taken in the context of the large body of literature that has used the behavioural test as a demonstration of the presence of tinnitus, these results are suggestive of objective neural correlates of the presence of noise-induced tinnitus and hyperacusis. PMID- 29191774 TI - Endogenous Pain Modulation Induced by Extrinsic and Intrinsic Psychological Threat in Healthy Individuals. AB - : Many factors interact to influence threat perception and the subsequent experience of pain. This study investigated the effect of observing pain (extrinsic threat) and intrinsic threat of pain to oneself on pressure pain threshold (PPT). Forty socially connected pairs of healthy volunteers were threat primed and randomly allocated to experimental or control roles. An experimental pain modulation paradigm was applied, with non-nociceptive threat cues used as conditioning stimuli. In substudy 1, the extrinsic threat to the experimental participant was observation of the control partner in pain. The control participant underwent hand immersion in noxious and non-noxious water baths in randomized order. Change in the observing participant's PPT from baseline to mid- and postimmersion was calculated. A significant interaction was found for PPT between conditions and test time (F2,78 = 24.9, P < .005). PPT increased by 23.6% +/- 19.3% between baseline and during hand immersion (F1,39 = 43.7, P < .005). Substudy 2 investigated threat of imminent pain to self. After a 15-minute break, the experimental participant's PPT was retested ("baseline 2"). Threat was primed by suggestion of whole arm immersion in an icier, larger water bath. PPT was tested immediately before anticipated arm immersion, after which the experiment ended. A significant increase in PPT between "baseline 2" and "pre-immersion" was seen (t = -7.6, P = .005), a pain modulatory effect of 25.8 +/- 20.7%. Extrinsic and intrinsic threat of pain, in the absence of any afferent input therefore influences pain modulation. This may need to be considered in studies that use noxious afferent input with populations who show dysfunctional pain modulation. PERSPECTIVE: The effect on endogenous analgesia of observing another's pain and of threat of pain to oneself was investigated. Extrinsic as well as intrinsic threat cues, in the absence of any afferent input, increased pain thresholds, suggesting that mere threat of pain may initiate analgesic effects in traditional noxious experimental paradigms. PMID- 29191775 TI - Agreement of different reference equations to classify patients with COPD as having reduced or preserved 6MWD. AB - BACKGROUND: Interpretation of the six-minute walk distance (6MWD) is enhanced by using recommended reference equations. Whenever possible, the choice of equation should be region-specific. A potential problem is that different equations for the 6MWD may have been developed for the same population, and it may be complicated to choose the most suitable. OBJECTIVE: To verify the agreement of different reference equations in classifying patients with Chronic Obstructive Pulmonary Disease (COPD) as having reduced or preserved 6MWD. METHODS: 159 patients with COPD performed the six-minute walk test according to international standardization. They were classified as having reduced 6MWD if it was below the lower limit of normal. Five Brazilian equations (Iwama; Britto1; Britto2; Dourado; Soares) and the two non-Brazilian equations most cited worldwide (Troosters; Enright) were used. The agreement for patients classified as reduced or preserved 6MWD was verified by Cohen's Kappa (pair-to-pair) analysis. The proportion of patients classified as having reduced walked distance was compared by the Chi-squared test. RESULTS: Agreement between equations varied largely in classifying subjects as having reduced or preserved 6MWD (Kappa: 0.10-0.82). Brazilian equations with the highest agreement were Iwama, Britto1 and Britto2 (Kappa>0.75). The proportion of patients classified as having reduced 6MWD was statistically similar only between equations in which the agreement was higher than 0.70. CONCLUSION: Even reference equations from the same country vary considerably in the classification of reduced or preserved 6MWD, and it is recommended that the region-specific ones be used as they give with higher agreement for similar and comparable interpretation of the patients' functional exercise capacity. PMID- 29191773 TI - Expression of channelrhodopsin-2 localized within the deep CA1 hippocampal sublayer in the Thy1 line 18 mouse. AB - Optogenetic proteins are powerful tools for advancing our understanding of neural circuitry. However, the precision of optogenetics is dependent in part on the extent to which expression is limited to cells of interest. The Thy1-ChR2 transgenic mouse is commonly used in optogenetic experiments. Although general expression patterns in these animals have been characterized, a detailed evaluation of cell-type specificity is lacking. This information is critical for interpretation of experimental results using these animals. We characterized ChR2 expression under the Thy1promoter in line 18 in comparison to known expression profiles of hippocampal cell types using immunohistochemistry in CA1. ChR2 expression did not colocalize with parvalbumin or calbindin expressing interneurons. However, we found ChR2 expression to be localized in the deep sublayer of CA1 in calbindin-negative pyramidal cells. These findings demonstrate the utility of the Thy1-ChR2-YFP mouse to study the activity and functional role of excitatory neurons located in the deep CA1 pyramidal cell layer. PMID- 29191777 TI - Clinical Significance of Plasma Epstein-Barr Virus DNA in Pulmonary Lymphoepithelioma-like Carcinoma (LELC) Patients. AB - INTRODUCTION: Primary pulmonary lymphoepithelioma-like carcinoma (LELC) is a histologically distinctive subtype of NSCLC and an Epstein-Barr virus (EBV) associated epithelial neoplasm. We investigated the clinical significance of plasma concentrations of EBV DNA in patients with pulmonary LELC. METHODS: Two independent sets of plasma samples from a total of 429 patients with patients with pulmonary LELC (287 initial and 142 confirmatory) were available for EBV DNA determination. Plasma samples from the patients were subjected to a real-time quantitative polymerase chain reaction before treatment and 3 months after radical resection. Cutoff points were determined for pretreatment plasma EBV DNA concentration (low <4000 copies/mL versus high >=4000 copies/mL) on the basis of a measure of heterogeneity with the log-rank test statistic with respect to overall survival (OS). The Kaplan-Meier method and Cox regression were used to evaluate the relationship between plasma EBV DNA concentrations and clinical outcome. Among patients with advanced-stage pulmonary LELC who underwent sequential blood draws, we evaluated the relationship between change in disease status and change in EBV DNA concentrations by using nonparametric tests. RESULTS: High EBV DNA concentration was associated with shorter OS in the initial, confirmatory, and combined data sets (combined data set hazard ratio = 3.67, 95% confidence interval: 2.72-4.38, p < 0.001). These findings persisted after multivariable adjustment. Compared with low EBV DNA concentration, high EBV DNA concentration was associated with shorter OS in patients with any stage of disease. High EBV DNA concentration was also associated with shorter disease-free survival (DFS) in patients with stage I/II disease. Patients with persistently detectable plasma EBV DNA had significantly poorer OS (p < 0.001) and DFS (p < 0.001) than did patients with undetectable EBV DNA 3 months after radical resection. In patients who underwent sequential evaluation of EBV DNA, an association was identified between an increase in EBV DNA concentration and a poor response to treatment and disease progression of pulmonary LELC. CONCLUSION: High baseline EBV DNA concentration is an independent poor prognostic marker in patients with pulmonary LELC. These results should be confirmed in larger prospective trials. PMID- 29191778 TI - Paraneoplastic Syndromes and Thymic Malignancies: An Examination of the International Thymic Malignancy Interest Group Retrospective Database. AB - INTRODUCTION: Thymic epithelial tumors (TETs) are associated with paraneoplastic/autoimmune (PN/AI) syndromes. Myasthenia gravis is the most common PN/AI syndrome associated with TETs. METHODS: The International Thymic Malignancy Interest Group retrospective database was examined to determine (1) baseline and treatment characteristics associated with PN/AI syndromes and (2) the prognostic role of PN/AI syndromes for patients with TETs. The competing risks model was used to estimate cumulative incidence of recurrence (CIR) and the Kaplan-Meier method was used to calculate overall survival (OS). A Cox proportional hazards model was used for multivariate analysis. RESULTS: A total of 6670 patients with known PN/AI syndrome status from 1951 to 2012 were identified. PN/AI syndromes were associated with younger age, female sex, thymoma histologic type, earlier stage, and an increased rate of total thymectomy and complete resection status. There was a statistically significant lower CIR in the group with a PN/AI syndrome than in the group without a PN/AI syndrome (10-year CIR 17.3% versus 21.2%, respectively [p = 0.0003]). The OS was improved in the group with a PN/AI syndrome compared to the group without a PN/AI syndrome (median OS 21.6 years versus 17.0 years, respectively [hazard ratio = 0.63, 95% confidence interval: 0.54-0.74, p < 0.0001]). However, in the multivariate model for recurrence-free survival and OS, PN/AI syndrome was not an independent prognostic factor. DISCUSSION: Previously, there have been mixed data regarding the prognostic role of PN/AI syndromes for patients with TETs. Here, using the largest data set in the world for TETs, PN/AI syndromes were associated with favorable features (i.e., earlier stage and complete resection status) but were not an independent prognostic factor for patients with TETs.

This growth has fueled the development of new imaging protocols and technologies in parallel to help facilitate these minimally-invasive procedures. Fusion imaging is an exciting new technology that combines the strength of 2 imaging modalities and has the potential to improve procedural planning and the safety of many commonly performed transcatheter procedures. In this review we discuss the basic concepts of fusion imaging along with the relative strengths and weaknesses of static vs dynamic fusion imaging modalities. This review will focus primarily on echocardiographic-fluoroscopic fusion imaging and its application in commonly performed transcatheter structural heart procedures.

AB - INTRODUCTION: The reported prevalence of ALK receptor tyrosine kinase gene (ALK) rearrangement in NSCLC ranges from 2% to 7%. The primary standard diagnostic method is fluorescence in situ hybridization (FISH). Recently, immunohistochemistry (IHC) has also proved to be a reproducible and sensitive technique. Reverse-transcriptase polymerase chain reaction (RT-PCR) has also been advocated, and most recently, the advent of targeted next-generation sequencing (NGS) for ALK and other fusions has become possible. This study compares anaplastic lymphoma kinase (ALK) evaluation with all four techniques in resected NSCLC from the large European Thoracic Oncology Platform Lungscape cohort. METHODS: A total of 96 cases from the European Thoracic Oncology Platform Lungscape iBiobank, with any ALK immunoreactivity were examined by FISH, central RT-PCR, and NGS. An H-score higher than 120 defines IHC positivity. RNA was extracted from the same formalin-fixed, paraffin-embedded tissues. For RT-PCR, primers covered the most frequent ALK translocations. For NGS, the Oncomine Solid Tumour Fusion Transcript Kit (Thermo Fisher Scientific, Waltham, MA) was used. The concordance was assessed using the Cohen kappa coefficient (two-sided alpha <= 5%). RESULTS: NGS provided results for 77 of the 95 cases tested (81.1%), whereas RT-PCR provided results for 77 of 96 (80.2%). Concordance occurred in 55 cases of the 60 cases tested with all four methods (43 ALK negative and 12 ALK positive). Using ALK copositivity for IHC and FISH as the criterion standard, we derived a sensitivity for RT-PCR/NGS of 70.0%/85.0%, with a specificity of 87.1%/79.0%. When either RT-PCR or NGS was combined with IHC, the sensitivity remained the same, whereas the specificity increased to 88.7% and 83.9% respectively. CONCLUSION: NGS evaluation with the Oncomine Solid Tumour Fusion transcript kit and RT-PCR proved to have high sensitivity and specificity, advocating their use in routine practice. For maximal sensitivity and specificity, ALK status should be assessed by using two techniques and a third one in discordant cases. We therefore propose a customizable testing algorithm. These findings significantly influence existing testing paradigms and have clear clinical and economic impact. PMID- 29191780 TI - The Value of the SYNTAX Score II in Predicting Clinical Outcomes in Patients Undergoing Transcatheter Aortic Valve Implantation. AB - INTRODUCTION AND OBJECTIVES: The predictive value of the SYNTAX score (SS) for clinical outcomes after transcatheter aortic valve implantation (TAVI) is very limited and could potentially be improved by the combination of anatomic and clinical variables, the SS-II. We aimed to evaluate the value of the SS-II in predicting outcomes in patients undergoing TAVI. METHODS: A total of 402 patients with severe symptomatic aortic stenosis undergoing transfemoral TAVI were included. Preprocedural TAVI angiograms were reviewed and the SS-I and SS-II were calculated using the SS algorithms. Patients were stratified in 3 groups according to SS-II tertiles. The coprimary endpoints were all-cause death and major adverse cardiovascular events (MACE), a composite of all-cause death, cerebrovascular event, or myocardial infarction at 1 year. RESULTS: Increased SS II was associated with higher 30-day mortality (P=.036) and major bleeding (P=.015). The 1-year risk of death and MACE was higher among patients in the 3rd SS-II tertile (HR, 2.60; P=.002 and HR, 2.66; P<.001) and was similar among patients in the 2nd tertile (HR, 1.27; P=.507 and HR, 1.05; P=.895) compared with patients in the 1st tertile. The highest SS-II tertile was an independent predictor of long-term mortality (P=.046) and MACE (P=.001). CONCLUSIONS: The SS II seems more suited to predict clinical outcomes in patients undergoing TAVI than the SS-I. Increased SS-II was associated with poorer clinical outcomes at 1 and 4 years post-TAVI, independently of the presence of coronary artery disease.

PMID- 29191783 TI - Executive-related oculomotor control is improved following a 10-min single-bout of aerobic exercise: Evidence from the antisaccade task. AB - Previous work has shown that a single-bout of moderate-to-vigorous intensity exercise improves task-specific activity within frontoparietal networks and produces a short-term 'boost' to executive-related cognitive control - an effect in healthy young adults that is reported to be selective to exercise durations of 20min or greater. The present study sought to determine whether such a 'boost' extends to an exercise duration as brief as 10min. Healthy young adults performed a 10-min single-bout of moderate-to-vigorous intensity aerobic exercise (i.e., via a cycle ergometer) and pre- and post-exercise executive control was examined via the antisaccade task. Antisaccades are an executive task requiring a goal directed eye movement (i.e., a saccade) mirror-symmetrical to a visual stimulus. The hands- and language-free nature of antisaccades coupled with the temporal precision of eye-tracking technology make it an ideal tool for identifying executive performance changes. Moreover, an extensive literature has shown that antisaccades are mediated via frontoparietal networks that are modulated following single-bout and chronic exercise training. Results showed that antisaccade reaction time (RT) reliably decreased by 27ms from pre- to post exercise assessments. Further, the percentage of antisaccade directional errors did not reliably vary from the pre- (13%) to post-exercise (9%) assessments - a result indicating that the RT improvement was unrelated to a speed-accuracy trade off. A follow-up experiment involving antisaccade sessions separated by a non exercise interval did not show a similar RT modulation. Thus, a 10-min bout of moderate-to-vigorous intensity aerobic exercise benefits executive-related oculomotor control, and is a finding we attribute to an exercise-based increase in attention/arousal and/or improved task-specific activity within the frontoparietal networks supporting antisaccades. PMID- 29191782 TI - Comparison of the Hemodynamic Performance of the Balloon-expandable SAPIEN 3 Versus Self-expandable Evolut R Transcatheter Valve: A Case-matched Study. AB - INTRODUCTION AND OBJECTIVES: The SAPIEN 3 (S3) valve and the Medtronic Evolut R (EVR) are second-generation transcatheter valves, designed to further reduce the rate of paravalvular aortic regurgitation (AoR). The aim of this study was to compare the 2 devices in terms of valve performance in a case-matched study with independent echocardiographic analysis. METHODS: Of a population of 201 patients who underwent transcatheter aortic valve implantation, 144 patients (S3, n = 80; EVR, n = 64) were matched according to aortic annulus diameter and aortic valve calcium score, as assessed by computed tomography. All echocardiographic examinations collected at baseline and at 1- and 6-month follow-up were centrally analyzed. RESULTS: The 2 groups were well balanced in baseline clinical and echocardiographic characteristics. The EVR valve showed a better hemodynamic profile as assessed by peak aortic gradient (EVR 13 +/- 7 vs S3 20 +/- 10mmHg; P<.001), mean aortic gradient (EVR 7 +/- 3 vs S3 11 +/- 6mmHg; P<.001), and Doppler velocity index (EVR 0.65+/-0.15 vs S3 0.51+/-0.16; P<.001). The rate of moderate-severe or any paravalvular (>= mild) AoR was higher in the EVR group (11% and 50%) than in the S3 group (2.5% and 21%; P <.05, respectively), with a larger number of paravalvular jets (P <.001). CONCLUSIONS: In a case-matched cohort of transcatheter aortic valve implantation patients, the S3 valve was associated with a lower rate of paravalvular AoR but also with a higher residual gradient than the EVR system. PMID- 29191784 TI - Nanoparticulate peptide delivery exclusively to the brain produces tolerance free analgesia. AB - The delivery of peptide drugs to the brain is challenging, principally due to the blood brain barrier and the low metabolic stability of peptides. Exclusive delivery to the brain with no peripheral exposure has hitherto not been demonstrated with brain quantification data. Here we show that polymer nanoparticles encapsulating leucine5-enkephalin hydrochloride (LENK) are able to transport LENK exclusively to the brain via the intranasal route, with no peripheral exposure and nanoparticle localisation is observed within the brain parenchyma. Animals dosed with LENK nanoparticles (NM0127) showed a strong anti nociceptive response in multiple assays of evoked and on going pain whereas animals dosed intranasally with LENK alone were unresponsive. Animals did not develop tolerance to the anti-hyperalgesic activity of NM0127 and NM0127 was active in morphine tolerant animals. A microparticulate formulation of clustered nanoparticles was prepared to satisfy regulatory requirements for nasal dosage forms and the polymer nanoparticles alone were found to be biocompatible, via the nasal route, on chronic dosing. PMID- 29191785 TI - Folate-targeted liposomal nitrooxy-doxorubicin: An effective tool against P glycoprotein-positive and folate receptor-positive tumors. AB - Drug efflux transporters, in particular P-glycoprotein (Pgp), limit the success of chemotherapy. We previously found that synthetic doxorubicin conjugated with nitric oxide (NO)-releasing group overcomes resistance by inducing a NO-mediated inhibition of Pgp. Here we produced the first liposomal formulations of this nitrooxy-doxorubicin decorated with folic acid (FA), termed LNDF, in order to improve their active targeting against Pgp-expressing tumors. Folate was inserted onto liposomes surface using two different methods and the formulations were compared with respect to their technological features and in vitro behavior. By analyzing human and murine breast cancer cells with different expression of FA receptor (FAR) and Pgp, we demonstrated that LNDF are internalized in a FAR dependent manner and achieve maximal anti-tumor efficacy against FAR-positive/Pgp positive cells. Upon uptake of LNDF, nitrooxy-doxorubicin was delivered within nucleus, where it induced cell cycle arrest and DNA damages, and mitochondria, where it impaired the mitochondrial energy metabolism and triggered mitochondria dependent apoptosis. LNDF reduced the growth of FAR-positive/Pgp-positive tumors and prevented tumor formation in mice, whereas doxorubicin and Caelyx(r) failed. LNDF cardiotoxicity was comparable to Caelyx(r). The sensitivity to LNDF was maintained in tumors exposed to repeated cycles of the drug and in cells derived from the exposed tumors, excluding the onset of secondary resistance. By combining an innovative multitarget cargo drug, conceived to achieve high efficacy against Pgp-expressing cells, and appropriate strategies of liposome formulation and decoration, we produced a therapeutic tool that may represent a significant advancement in the treatment of FAR-positive/Pgp-positive tumors. PMID- 29191786 TI - KIR-HLA distribution in a Vietnamese population from Hanoi. AB - The KIR (killer cell immunoglobulin-like receptors) gene family codifies a group of receptors that recognize human leukocyte antigens (HLA) and modulate natural killer (NK) cells response. Genetic diversity of KIR genes and HLA ligands has not yet been deeply investigated in South East Asia. Here, we characterized KIR gene presence and absence polymorphism of 14 KIR genes and two pseudogenes, as well as the frequencies of the ligands HLA-Bw4, HLA-C1 and HLA-C2 in a Vietnamese population from Hanoi (n = 140). Genotyping was performed by polymerase chain reaction with specific sequence primers (PCR-SSP). We compared KIR frequencies and performed principal component analysis with 43 worldwide populations of different ancestries. KIR carrier frequencies in Vietnamese were similar to those reported for Thai and Chinese Han, but differed significantly from other geographically close populations such as Japanese and South Korean. This similarity was also observed in KIR gene-content genotypes and is in accordance with the origin from Southern China and Thailand proposed for the Vietnamese population. The frequencies of HLA ligands observed in Vietnamese did not differ from those reported for other East-Asian populations (p > .05). Studies regarding KIR-HLA in populations are of prime importance to understand their evolution, function and role in diseases. PMID- 29191787 TI - Post-translational regulation of metabolism in fumarate hydratase deficient cancer cells. AB - Deregulated signal transduction and energy metabolism are hallmarks of cancer and both play a fundamental role in tumorigenesis. While it is increasingly recognised that signalling and metabolism are highly interconnected, the underpinning mechanisms of their co-regulation are still largely unknown. Here we designed and acquired proteomics, phosphoproteomics, and metabolomics experiments in fumarate hydratase (FH) deficient cells and developed a computational modelling approach to identify putative regulatory phosphorylation-sites of metabolic enzymes. We identified previously reported functionally relevant phosphosites and potentially novel regulatory residues in enzymes of the central carbon metabolism. In particular, we showed that pyruvate dehydrogenase (PDHA1) enzymatic activity is inhibited by increased phosphorylation in FH-deficient cells, restricting carbon entry from glucose to the tricarboxylic acid cycle. Moreover, we confirmed PDHA1 phosphorylation in human FH-deficient tumours. Our work provides a novel approach to investigate how post-translational modifications of enzymes regulate metabolism and could have important implications for understanding the metabolic transformation of FH-deficient cancers with potential clinical applications. PMID- 29191788 TI - Progressive impairment of atrial myocyte function during left ventricular hypertrophy and heart failure. AB - Hypertensive heart disease (HHD) can cause left ventricular (LV) hypertrophy and heart failure (HF). It is unclear, though, which factors may contribute to the transition from compensated LV hypertrophy to HF in HHD. We hypothesized that maladaptive atrial remodeling with impaired atrial myocyte function would occur in advanced HHD and may be associated with the emergence of HF. Experiments were performed on atrial myocytes and tissue from old (15-25months) normotensive Wistar-Kyoto rats (WKY) and spontaneously hypertensive rats (SHR) with advanced HHD. Based on the absence or presence of elevated lung weight, a sign of lung congestion and heart failure, SHR were divided into a non-failing (SHR-NF) and failing (SHR-HF) group. Compared with WKY, SHR exhibited elevated blood pressure, LV hypertrophy and left atrial (LA) hypertrophy with increased LA expression of markers of hypertrophy and fibrosis. SHR-HF were distinguished from SHR-NF by aggravated hypertrophy and fibrosis. SHR-HF atrial myocytes exhibited reduced contractility and impaired SR Ca2+ handling. Moreover, in SHR the expression and phosphorylation of SR Ca2+-regulating proteins (SERCA2a, calsequestrin, RyR2 and phospholamban) showed negative correlation with increasing lung weight. Increasing stimulation frequency (1-2-4Hz) of atrial myocytes caused a progressive increase in arrhythmogenic Ca2+ release (including alternans), which was observed most frequently in SHR-HF. Thus, in old SHR with advanced HHD there is profound structural and functional atrial remodeling. The occurrence of HF in SHR is associated with LA and RA hypertrophy, increased atrial fibrosis, impaired atrial myocyte contractility and SR Ca2+ handling and increased propensity for arrhythmogenic Ca2+ release. Therefore, functional remodeling intrinsic to atrial myocytes may contribute to the transition from compensated LV hypertrophy to HF in advanced HHD and an increased propensity of atrial arrhythmias in HF. PMID- 29191789 TI - Accidental sulfur mustard exposure: A case report. AB - The clinical progression following a sulfur mustard-induced skin exposure is well documented in the literature. Upon skin contact and a characteristic latency period, sulfur mustard (SM) causes erythema, blister formation and ulceration, which is associated with wound healing disorders that may require surgical treatment. Here, we present a case report of accidental exposure to SM in a laboratory setting which required surgical treatment of the skin. The case was illustrated at close intervals over a period of two years and underlines that exposure to SM has to be taken into account when typical clinical symptoms occur. Moreover skin grafts appear to be effective in SM-induced non healing skin ulcerations. PMID- 29191790 TI - Morphological and transcriptomic effects of endocrine modulators on the gonadal differentiation of chicken embryos: The case of tributyltin (TBT). AB - Morphological malformations induced by tributyltin (TBT) exposure during embryonic development have already been characterized in various taxonomic groups, but, nonetheless, the molecular processes underlying these changes remain obscure. The present study provides the first genome-wide screening for differentially expressed genes that are linked to morphological alterations of gonadal tissue from chicken embryos after exposure to TBT. We applied a single injection of TBT (between 0.5 and 30 pg as Sn/g egg) into incubated fertile eggs to simulate maternal transfer of the endocrine disruptive compound. Methyltestosterone (MT) served as a positive control (30 pg/g egg). After 19 days of incubation, structural features of the gonads as well as genome-wide gene expression profiles were assessed simultaneously. TBT induced significant morphological and histological malformations of gonadal tissue from female embryos that show a virilization of the ovaries. This phenotypical virilization was mirrored by altered expression profiles of sex-dependent genes. Among these are several transcription and growth factors (e.g. FGF12, CTCF, NFIB), whose altered expression might serve as a set of markers for early identification of endocrine active chemicals that affect embryonic development by transcriptome profiling without the need of elaborate histological analyses. PMID- 29191791 TI - Electrophysiological investigation of the effect of structurally different bispyridinium non-oxime compounds on human alpha7-nicotinic acetylcholine receptor activity-An in vitro structure-activity analysis. AB - Organophosphorus compounds, including nerve agents and pesticides, exert their toxicity through irreversible inhibition of acetylcholinesterase (AChE) resulting in an accumulation of acetylcholine and functional impairment of muscarinic and nicotinic acetylcholine receptors. Current therapy comprises oximes to reactivate AChE and atropine to antagonize effects induced by muscarinic acetylcholine receptors. Nicotinic malfunction leading to depression of the central and peripheral respiratory system is not directly treated calling for alternative therapeutic interventions. In the present study, we investigated the electrophysiological properties of the human nAChR subtype alpha7 (halpha7-nAChR) and the functional effect of the 4-tert-butyl bispyridinium (BP) compound MB327 and of a series of novel substituted bispyridinium compounds on the receptors by an automated patch clamp technique. Activation of halpha7-nAChRs was induced by nicotine and acetylcholine demonstrating rapid cationic influx up to 100MUM. Agonist-induced currents decayed within a few milliseconds revealing fast desensitization of the receptors. Application of higher agonist concentrations led to a decline of current amplitudes which seemed to be due to increasing receptor desensitization. When 100MUM of agonist was coapplied with low concentrations of the well characterized alpha7-specific positive allosteric modulator PNU-120596 (1MUM-10MUM), the maximum response and duration of nAChR activation were markedly augmented indicating an elongated mean open-time of receptors and prevention of receptor desensitization. However, co-application of increasing PNU-120596 concentrations (>10MUM) with agonist induced a decline of potentiated current responses. Although less pronounced than PNU-120596, six of the twenty tested substituted BP compounds, in particular those with a substituent at 3-position and 4-position at the pyridinium moieties, were found to potentiate current responses of halpha7-nAChRs, most pronounced MB327.This effect was clearly depended on the presence of the agonist indicating a positive allosteric mechanism of these compounds. Besides potentiation at low concentrations, these compounds seem to interact at different binding sites on halpha7-nAChRs since enhancement decreased at high concentrations. The residual fourteen BP compounds, possessing either an isopropyl-group or more than one group at the pyridinium moiety, antagonized nicotinic currents exhibiting IC50 of low up to high micromolar concentrations (~1MUM-300MUM). PMID- 29191792 TI - The binding efficiency of RPA to telomeric G-strands folded into contiguous G quadruplexes is independent of the number of G4 units. AB - Replication protein A (RPA) is a single-stranded DNA binding protein involved in replication and in telomere maintenance. During telomere replication, G quadruplexes (G4) can accumulate on the lagging strand template and need to be resolved. It has been shown that human RPA is able to unfold a single G4. Nevertheless, the G-strand of human telomeres is prone to fold into higher-order structures formed by contiguous G-quadruplexes. To understand how RPA deals with these structures, we studied its interaction with telomeric G-strands folding into an increasing number of contiguous G4s. The aim of this study was to determine whether the efficiency of binding/unfolding of hRPA to telomeric G strands depends on the number of G4 units. Our data show that the number n of contiguous G4 units (n >= 2) does not affect the efficiency of hRPA to coat transiently exposed single-stranded telomeric G-strands. This feature may be essential in preventing instability due to G4 structures during telomere replication. PMID- 29191793 TI - Combined therapies to treat complex diseases: The role of the gut microbiota in multiple sclerosis. AB - The commensal microbiota has emerged as an environmental risk factor for multiple sclerosis (MS). Studies in experimental autoimmune encephalomyelitis (EAE) models have shown that the commensal microbiota is an essential player in triggering autoimmune demyelination. Likewise, the commensal microbiota modulates the host immune system, alters the integrity and function of biological barriers and has a direct effect on several types of central nervous system (CNS)-resident cells. Moreover, a characteristic gut dysbiosis has been recognized as a consistent feature during the clinical course of MS, and the MS-related microbiota is gradually being elucidated. This review highlights animal studies in which commensal microbiota modulation was tested in EAE, as well as the mechanisms of action and influence of the commensal microbiota not only in the local milieu but also in the innate and adaptive immune system and the CNS. Regarding human research, this review focuses on studies that show how the commensal microbiota might act as a pathogenic environmental risk factor by directing immune responses towards characteristic pathogenic profiles of MS. We speculate how specific microbiome signatures could be obtained and used as potential pathogenic events and biomarkers for the clinical course of MS. Finally, we review recently published and ongoing clinical trials in MS patients regarding the immunomodulatory properties exerted by some microorganisms. Because MS is a complex disease with a large variety of associated environmental risk factors, we suggest that current treatments combined with strategies that modulate the commensal microbiota would constitute a broader immunotherapeutic approach and improve the clinical outcome for MS patients. PMID- 29191794 TI - The antennae of damselfly larvae. AB - The larval antennal sensilla of two Zygoptera species, Calopteryx haemorroidalis (Calopterygidae) and Ischnura elegans (Coenagrionidae) are investigated with SEM and TEM. These two species have different antennae (geniculate, setaceous) and live in different environments (lotic, lentic waters). Notwithstanding this, similarities in the kind and distribution of sensilla are outlined: in both species the majority of sensilla types is located on the apical portion of the antenna, namely a composed coeloconic sensillum (possible chemoreceptor), two other coeloconic sensilla (possible thermo-hygroreceptors) and an apical seta (direct contact mechanoreceptor). Other mechanoreceptors, such as filiform hairs sensitive to movements of the surrounding medium or bristles positioned to sense the movements of the flagellar segments, are present on the antenna. Similarities in the antennal sensilla types and distribution are observed also with other dragonfly species, such as Onychogomphus forcipatus and Libellula depressa. A peculiar structure with an internal organization similar to that of a gland is observed in the apical antenna of C. haemorroidalis and I. elegans and it is present also in O. forcipatus and L. depressa. The possible function of this structure is at the moment unknown but deserves further investigations owing to its widespread presence in Odonata larvae. PMID- 29191795 TI - Glucan-MOS(r) improved growth and innate immunity in pacu stressed and experimentally infected with Aeromonas hydrophila. AB - We tested the efficacy of a commercial product (Glucan-MOS(r)) derived from yeast Saccharomyces cerevisiae, containing two combined products, beta-1,3-1,6 glucans and mannans on the growth, feed efficiency, stress and innate immune responses of juvenile pacu (Piaractus mesopotamicus) after a stressful handling and bacterial inoculation. For this, we evaluated the serum cortisol and plasma glucose levels, the respiratory activity of leukocytes, the serum lysozyme levels, as well as the number of circulating erythrocytes and leukocytes of fish fed during 30 days with diets containing increased levels of Glucan-MOS (0.0, 0.1, 0.2, 0.4 and 0.8%). The supplementation of 0.1% improved weight gain, feed conversion and the protein efficiency ratio compared to a control diet. The 0.2 and 0.4% Glucan-MOS(r) diets were sufficient to increase the respiratory burst of leukocytes and lysozyme activity, the number of thrombocytes, neutrophils and monocytes in the blood after a stressful handling and bacterial challenge, and minimized stress response as shown by decreased cortisol and glucose levels when compared to the control. The results of this work reinforce the benefits of the adoption of feeding strategies including combination of both beta-1,3-1,6 glucans and mannans as a dietary supplement in periods prior to intensive management. The 30-day period was sufficient to stimulate growth performance, improve nutrient utilization, minimize stress response and modulate innate immunity responses. PMID- 29191796 TI - De novo transcriptome assembly and analysis of differential gene expression following lipopolysaccharide challenge in Pelteobagrus fulvidraco. AB - The yellow catfish, Pelteobagrus fulvidraco, has been recognized as an important freshwater aquaculture species in Eastern and Southeast Asia. To gain a better understanding of the immune response in P. fulvidraco, we analyzed its transcriptome following stimulation with lipopolysaccharide (LPS). Phosphate buffer saline (PBS) was used as control. Following assembly and annotation, 72,152 unigenes with an average length of 1090 bp were identified. A total of 370 differentially expressed genes (DEGs) in the P. fulvidraco were observed at 12 h post LPS treatment, including 197 up-regulated genes and 173 down-regulated genes. Clusters of Orthologous Groups of proteins (KOG/COG) annotation demonstrated that a total of 18,819 unigenes classified into 26 categories. Gene ontology (GO) analysis revealed 20 biological process subcategories, 7 cellular component subcategories and 20 molecular function subcategories. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis identified immune responses pathways. Quantitative reverse transcription polymerase chain reaction measured the expression of 18 genes involved in the immune response. CXCL2-like chemokine (CXCL2), goose-type lysozyme (LYZ G), and cathepsin K (CTSK) were significantly up-regulated. This study enriches the P. fulvidraco transcriptome database and provides insight into the immune response of P. fulvidraco against infection. PMID- 29191797 TI - Web-Based Intervention to Teach Developmentally Supportive Care to Parents of Preterm Infants: Feasibility and Acceptability Study. AB - BACKGROUND: Preterm birth affects 8% to 11% of the population and conveys a significant risk of developmental delays. Intervention programs that support child development have been shown to have a positive impact on early motor and cognitive development and on parental well-being. However, these programs are often difficult to implement in a real-life setting due to lack of resources. Hence, our multidisciplinary team developed Mieux Agir au Quotidien (MAQ) to teach developmentally supportive care to parents of preterm infants with the goal of improving child development and parental outcomes. Our intervention included 3 in-person workshops that occurred prior to hospital discharge and a Web-based platform with written and videotaped materials that addressed 5 main themes: (1) infant behavioral cues, (2) flexion positioning; (3) oral feeding support, (4) parent-infant interactions, and (5) anticipation of developmental milestones. OBJECTIVE: This study aimed to test the feasibility and acceptability of the intervention by parents of preterm infants and assess clinical benefits on child neurodevelopment and parental outcomes during the first year of life. METHODS: A total of 107 infants born at <30 weeks and admitted to Sainte-Justine Hospital neonatal intensive care unit and their parents were enrolled in a nonrandomized controlled before-and-after interventional study (intervention n=55, comparison n=52). Acceptability of the program was assessed with a user satisfaction questionnaire. When the infants were at 4 months' corrected age, all parents completed questionnaires on infant temperament, parenting stress, sense of competence, and parenting satisfaction. At 12 months' corrected age, neurodevelopmental testing was performed on infants using the Alberta Infant Motor Scale and the Bayley Scales of Infant and Toddler Development, Third Edition. Comparisons between the 2 groups were done using independent t tests, Wilcoxon rank-sum tests, and Fisher exact tests. RESULTS: The majority of parents (43/45) were satisfied with the intervention program and all would recommend MAQ to others. MAQ met their need for evidence-based information that proved useful to support their child development. No difference in parental or child neurodevelopmental outcomes was detected in this pilot study for most outcomes except for higher median scores for parental coercive behaviors in the intervention group, although proportions scoring in the coercive range did not differ. CONCLUSIONS: Acceptability of the program was high among parents thus supporting the relevance of such intervention. A larger study using a randomized controlled trial design is needed to better document impact on parent and children and investigate how Web-based technologies can efficiently complement individualized intervention to alleviate the burden on health care resources. PMID- 29191798 TI - Using Android and Open Data Kit Technology in Data Management for Research in Resource-Limited Settings in the Niger Delta Region of Nigeria: Cross-Sectional Household Survey. AB - BACKGROUND: Data collection in Sub-Saharan Africa has traditionally been paper based. However, the popularization of Android mobile devices and data capture software has brought paperless data management within reach. We used Open Data Kit (ODK) technology on Android mobile devices during a household survey in the Niger Delta region of Nigeria. OBJECTIVE: The aim of this study was to describe the pros and cons of deploying ODK for data management. METHODS: A descriptive cross-sectional household survey was carried out by 6 data collectors between April and May 2016. Data were obtained from 1706 persons in 601 households across 6 communities in 3 states in the Niger Delta. The use of Android mobile devices and ODK technology involved form building, testing, collection, aggregation, and download for data analysis. The median duration for data collection per household and per individual was 25.7 and 9.3 min, respectively. RESULTS: Data entries per device ranged from 33 (33/1706, 1.93%) to 482 (482/1706, 28.25%) individuals between 9 (9/601, 1.5%) and 122 (122/601, 20.3%) households. The most entries (470) were made by data collector 5. Only 2 respondents had data entry errors (2/1706, 0.12%). However, 73 (73/601, 12.1%) households had inaccurate date and time entries for when data collection started and ended. The cost of deploying ODK was estimated at US $206.7 in comparison with the estimated cost of US $466.7 for paper-based data management. CONCLUSIONS: We found the use of mobile data capture technology to be efficient and cost-effective. As Internet services improve in Africa, we advocate their use as effective tools for health information management.

PMID- 29191799 TI - Implementation of a Web-Based Organ Donation Educational Intervention: Development and Use of a Refined Process Evaluation Model. AB - BACKGROUND: The lack of available organs is often considered to be the single greatest problem in transplantation today. Internet use is at an all-time high, creating an opportunity to increase public commitment to organ donation through the broad reach of Web-based behavioral interventions. Implementing Internet interventions, however, presents challenges including preventing fraudulent respondents and ensuring intervention uptake. Although Web-based organ donation interventions have increased in recent years, process evaluation models appropriate for Web-based interventions are lacking. OBJECTIVE: The aim of this study was to describe a refined process evaluation model adapted for Web-based settings and used to assess the implementation of a Web-based intervention aimed to increase organ donation among African Americans. METHODS: We used a randomized pretest-posttest control design to assess the effectiveness of the intervention website that addressed barriers to organ donation through corresponding videos. Eligible participants were African American adult residents of Georgia who were not registered on the state donor registry. Drawing from previously developed process evaluation constructs, we adapted reach (the extent to which individuals were found eligible, and participated in the study), recruitment (online recruitment mechanism), dose received (intervention uptake), and context (how the Web-based setting influenced study implementation) for Internet settings and used the adapted model to assess the implementation of our Web-based intervention. RESULTS: With regard to reach, 1415 individuals completed the eligibility screener; 948 (67.00%) were determined eligible, of whom 918 (96.8%) completed the study. After eliminating duplicate entries (n=17), those who did not initiate the posttest (n=21) and those with an invalid ZIP code (n=108), 772 valid entries remained. Per the Internet protocol (IP) address analysis, only 23 of the 772 valid entries (3.0%) were within Georgia, and only 17 of those were considered unique entries and could be considered for analyses. With respect to recruitment, 517 of the 772 valid entries (67.0%) of participants were recruited from a Web recruiter. Regarding dose received, no videos from the intervention website were watched in their entirety, and the average viewing duration was 17 seconds over the minimum. With respect to context, context analysis provided us with valuable insights into factors in the Internet environment that may have affected study implementation. Although only active for a brief period of time, the Craigslist website advertisement may have contributed the largest volume of fraudulent responses. CONCLUSIONS: We determined fraud and low uptake to be serious threats to this study and further confirmed the importance of conducting a process evaluation to identify such threats. We suggest checking participants' IP addresses before study initiation, selecting software that allows for automatic duplicate protection, and tightening minimum requirements for intervention uptake. Further research is needed to understand how process evaluation models can be used to monitor implementation of Web-based studies. PMID- 29191800 TI - Implementation Intention and Reminder Effects on Behavior Change in a Mobile Health System: A Predictive Cognitive Model. AB - BACKGROUND: Implementation intentions are mental representations of simple plans to translate goal intentions into behavior under specific conditions. Studies show implementation intentions can produce moderate to large improvements in behavioral goal achievement. Human associative memory mechanisms have been implicated in the processes by which implementation intentions produce effects. On the basis of the adaptive control of thought-rational (ACT-R) theory of cognition, we hypothesized that the strength of implementation intention effect could be manipulated in predictable ways using reminders delivered by a mobile health (mHealth) app. OBJECTIVE: The aim of this experiment was to manipulate the effects of implementation intentions on daily behavioral goal success in ways predicted by the ACT-R theory concerning mHealth reminder scheduling. METHODS: An incomplete factorial design was used in this mHealth study. All participants were asked to choose a healthy behavior goal associated with eat slowly, walking, or eating more vegetables and were asked to set implementation intentions. N=64 adult participants were in the study for 28 days. Participants were stratified by self-efficacy and assigned to one of two reminder conditions: reminders-presented versus reminders-absent. Self-efficacy and reminder conditions were crossed. Nested within the reminders-presented condition was a crossing of frequency of reminders sent (high, low) by distribution of reminders sent (distributed, massed). Participants in the low frequency condition got 7 reminders over 28 days; those in the high frequency condition were sent 14. Participants in the distributed conditions were sent reminders at uniform intervals. Participants in the massed distribution conditions were sent reminders in clusters. RESULTS: There was a significant overall effect of reminders on achieving a daily behavioral goal (coefficient=2.018, standard error [SE]=0.572, odds ratio [OR]=7.52, 95% CI 0.9037-3.2594, P<.001). As predicted by ACT-R, using default theoretical parameters, there was an interaction of reminder frequency by distribution on daily goal success (coefficient=0.7994, SE=0.2215, OR=2.2242, 95% CI 0.3656-1.2341, P<.001). The total number of times a reminder was acknowledged as received by a participant had a marginal effect on daily goal success (coefficient=0.0694, SE=0.0410, OR=1.0717, 95% CI -0.01116 to 0.1505, P=.09), and the time since acknowledging receipt of a reminder was highly significant (coefficient=-0.0490, SE=0.0104, OR=0.9522, 95% CI -0.0700 to -0.2852], P<.001). A dual system ACT-R mathematical model was fit to individuals' daily goal successes and reminder acknowledgments: a goal-striving system dependent on declarative memory plus a habit-forming system that acquires automatic procedures for performance of behavioral goals. CONCLUSIONS: Computational cognitive theory such as ACT-R can be used to make precise quantitative predictions concerning daily health behavior goal success in response to implementation intentions and the dosing schedules of reminders.

PMID- 29191802 TI - Peripheral Neuropathy Induced by Microtubule-Targeted Chemotherapies: Insights into Acute Injury and Long-term Recovery. AB - Chemotherapy-induced peripheral neuropathy (CIPN) is a major cause of disability in cancer survivors. CIPN investigations in preclinical model systems have focused on either behaviors or acute changes in nerve conduction velocity (NCV) and amplitude, but greater understanding of the underlying nature of axonal injury and its long-term processes is needed as cancer patients live longer. In this study, we used multiple independent endpoints to systematically characterize CIPN recovery in mice exposed to the antitubulin cancer drugs eribulin, ixabepilone, paclitaxel, or vinorelbine at MTDs. All of the drugs ablated intraepidermal nerve fibers and produced axonopathy, with a secondary disruption in myelin structure within 2 weeks of drug administration. In addition, all of the drugs reduced sensory NCV and amplitude, with greater deficits after paclitaxel and lesser deficits after ixabepilone. These effects correlated with degeneration in dorsal root ganglia (DRG) and sciatic nerve and abundance of Schwann cells. Although most injuries were fully reversible after 3-6 months after administration of eribulin, vinorelbine, and ixabepilone, we observed delayed recovery after paclitaxel that produced a more severe, pervasive, and prolonged neurotoxicity. Compared with other agents, paclitaxel also displayed a unique prolonged exposure in sciatic nerve and DRG. The most sensitive indicator of toxicity was axonopathy and secondary myelin changes accompanied by a reduction in intraepidermal nerve fiber density. Taken together, our findings suggest that intraepidermal nerve fiber density and changes in NCV and amplitude might provide measures of axonal injury to guide clinical practice.Significance: This detailed preclinical study of the long-term effects of widely used antitubulin cancer drugs on the peripheral nervous system may help guide clinical evaluations to improve personalized care in limiting neurotoxicity in cancer survivors.

AB - Atrial fibrillation (AF), which is the most diagnosed arrhythmia, is becoming a significant issue for health policy-makers. In particular, more and more attention is being devoted to AF prevention. Indeed, several studies recently published point out how targeted interventions could be useful in reducing the risk of AF occurrence (or recurrence). In this review, we briefly summarised the role of the major risk factors associated with the incidence of AF, as well as the effectiveness of interventions aimed at controlling these risk factors. Several general risk factors, such as alcohol consumption, physical activity, smoking habit, as well as specific cardiovascular risk factors as diabetes mellitus, hypertension and obesity have a relevant impact in determining the occurrence of AF, along with a strong clinical evidence of a dose-effect response mechanism for most of the factors examined. Specific interventions aimed at controlling risk factors have been showed to clearly reduce the risk of AF in several cohorts. Even more importantly, integrated programmes aimed at controlling for multiple risk factors would be more efficient in terms of reducing risk of AF, in particular whena stricter control is observed. AF prevention requires a series of initiatives focused on the many risk factors that we reviewed, as well as a more integrated approach, which should involve many stakeholders at different levels. In this light and also considering the constantly changing epidemiology, AF prevention may constitute a future 'win-win' strategy for all the stakeholders. PMID- 29191807 TI - DNA Methyltransferase 1-Dependent DNA Hypermethylation Constrains Arteriogenesis by Augmenting Shear Stress Set Point. AB - BACKGROUND: Arteriogenesis is initiated by increased shear stress and is thought to continue until shear stress is returned to its original "set point." However, the molecular mechanism(s) through which shear stress set point is established by endothelial cells (ECs) are largely unstudied. Here, we tested the hypothesis that DNA methyltransferase 1 (DNMT1)-dependent EC DNA methylation affects arteriogenic capacity via adjustments to shear stress set point. METHODS AND RESULTS: In femoral artery ligation-operated C57BL/6 mice, collateral artery segments exposed to increased shear stress without a change in flow direction (ie, nonreversed flow) exhibited global DNA hypermethylation (increased 5 methylcytosine staining intensity) and constrained arteriogenesis (30% less diameter growth) when compared with segments exposed to both an increase in shear stress and reversed-flow direction. In vitro, ECs exposed to a flow waveform biomimetic of nonreversed collateral segments in vivo exhibited a 40% increase in DNMT1 expression, genome-wide hypermethylation of gene promoters, and a DNMT1 dependent 60% reduction in proarteriogenic monocyte adhesion compared with ECs exposed to a biomimetic reversed-flow waveform. These results led us to test whether DNMT1 regulates arteriogenic capacity in vivo. In femoral artery ligation operated mice, DNMT1 inhibition rescued arteriogenic capacity and returned shear stress back to its original set point in nonreversed collateral segments. CONCLUSIONS: Increased shear stress without a change in flow direction initiates arteriogenic growth; however, it also elicits DNMT1-dependent EC DNA hypermethylation. In turn, this diminishes mechanosensing, augments shear stress set point, and constrains the ultimate arteriogenic capacity of the vessel. This epigenetic effect could impact both endogenous collateralization and treatment of arterial occlusive diseases. PMID- 29191808 TI - Suberanilohydroxamic Acid as a Pharmacological Kruppel-Like Factor 2 Activator That Represses Vascular Inflammation and Atherosclerosis. AB - BACKGROUND: Kruppel-like factor 2 (KLF2) is an important zinc-finger transcription factor that maintains endothelial homeostasis by its anti inflammatory, -thrombotic, -oxidative, and -proliferative effects in endothelial cells. In light of the potent vasoprotective effects of KLF2, modulating KLF2 expression or function could give rise to new therapeutic strategies to treat cardiovascular diseases. METHODS AND RESULTS: High-throughput drug screening based on KLF2 promoter luciferase reporter assay was performed to screen KLF2 activators. Real-time PCR and western blot were used to detect gene and protein expression. Identified KLF2 activator was orally administered to ApoE-/- mice to evaluate anti-atherosclerotic efficacy. By screening 2400 compounds in the Spectrum library, we identified suberanilohydroxamic (SAHA) acid, also known as vorinostat as a pharmacological KLF2 activator through myocyte enhancer factor 2. We found that SAHA exhibited anti-inflammatory effects and attenuated monocyte adhesion to endothelial cells inflamed with tumor necrosis factor alpha. We further showed that the inhibitory effect of SAHA on endothelial inflammation and ensuing monocyte adhesion was KLF2 dependent using KLF2-deficient mouse lung endothelial cells or KLF2 small interfering RNA- depleted human endothelial cells. Importantly, we observed that oral administration of SAHA reduced diet induced atherosclerotic lesion development in ApoE-/- mice without significant effect on serum lipid levels. CONCLUSIONS: These results demonstrate that SAHA has KLF2-dependent anti-inflammatory effects in endothelial cells and provide the proof of concept that KLF2 activation could be a promising therapeutic strategy for treating atherosclerosis.

AB - BACKGROUND: Clinical decision making in abdominal aortic aneurysms (AAA) relies completely on diameter. At this point, improved decision tools remain an unmet medical need. Our goal was to identify changes at the molecular level specifically leading up to AAA rupture. METHODS AND RESULTS: Aortic wall tissue specimens were collected during open elective (eAAA; n=31) or emergency repair of ruptured AAA (rAAA; n=17), and gene expression was investigated using microarrays. Identified candidate genes were validated with quantitative real time polymerase chain reaction in an independent sample set (eAAA: n=46; rAAA: n=18). Two gene sets were identified, 1 set containing 5 genes linked to terminal progression, that is, positively associated with progression of larger AAA, and with rupture (HILPDA, ANGPTL4, LOX, SRPX2, FCGBP), and a second set containing 5 genes exclusively upregulated in rAAA (ADAMTS9, STC1, GFPT2, GAL3ST4, CCL4L1). Genes in both sets essentially associated with processes related to impaired tissue remodeling, such as angiogenesis and adipogenesis. In gene expression experiments we were able to show that upregulated gene expression for identified candidate genes is unique for AAA. Functionally, the selected upregulated factors converge at processes coordinated by the canonical HIF-1alpha signaling pathway and are highly expressed in fibroblasts but not inflammatory cells of the aneurysmatic wall. Histological quantification of angiogenesis and exploration of the HIF-1alpha network in rAAA versus eAAA shows enhanced microvessel density but also clear activation of the HIF-1alpha network in rAAA. CONCLUSIONS: Our study shows a specific molecular fingerprint for terminal AAA disease. These changes appear to converge at activation of HIF-1alpha signaling in mesenchymal cells. Aspects of this cascade might represent targets for rupture risk assessment. PMID- 29191811 TI - Neonatal mannequin comparison of the Upright self-inflating bag and snap-fit mask versus standard resuscitators and masks: leak, applied load and tidal volumes. AB - OBJECTIVE: Neonatal mask ventilation is a difficult skill to acquire and maintain. Mask leak is common and can lead to ineffective ventilation. The aim of this study was to determine whether newly available neonatal self-inflating bags and masks could reduce mask leak without additional load being applied to the face. DESIGN: Forty operators delivered 1 min episodes of mask ventilation to a mannequin using the Laerdal Upright Resuscitator, a standard Laerdal infant resuscitator (Laerdal Medical) and a T-Piece Resuscitator (Neopuff), using both the Laerdal snap-fit face mask and the standard Laerdal size 0/1 face mask (equivalent sizes). Participants were asked to use pressure sufficient to achieve 'appropriate' chest rise. Leak, applied load, airway pressure and tidal volume were measured continuously. Participants were unaware that load was being recorded. RESULTS: There was no difference in mask leak between resuscitation devices. Leak was significantly lower when the snap-fit mask was used with all resuscitation devices, compared with the standard mask (14% vs 37% leak, P<0.01). The snap-fit mask was preferred by 83% of participants. The device-mask combinations had no significant effect on applied load. CONCLUSIONS: The Laerdal Upright Resuscitator resulted in similar leak to the other resuscitation devices studied, and did not exert additional load to the face and head. The snap-fit mask significantly reduced overall leak with all resuscitation devices and was the mask preferred by participants. PMID- 29191812 TI - Physiologically based cord clamping stabilises cardiac output and reduces cerebrovascular injury in asphyxiated near-term lambs. AB - BACKGROUND: Physiologically based cord clamping (PBCC) has advantages over immediate cord clamping (ICC) during preterm delivery, but its efficacy in asphyxiated infants is not known. We investigated the physiology of PBCC following perinatal asphyxia in near-term lambs. METHODS: Near-term sheep fetuses (139+/-2 (SD) days' gestation) were instrumented to measure umbilical, carotid, pulmonary and femoral arterial flows and pressures. Systemic and cerebral oxygenation was recorded using pulse oximetry and near-infrared spectroscopy, respectively. Fetal asphyxia was induced until mean blood pressure reached ~20 mm Hg, where lambs underwent ICC and initiation of ventilation (n=7), or ventilation for 15 min prior to umbilical cord clamping (PBCC; n=8). Cardiovascular parameters were measured and white and grey matter microvascular integrity assessed using qRT-PCR and immunohistochemistry. RESULTS: PBCC restored oxygenation and cardiac output at the same rate and in a similar fashion to lambs resuscitated following ICC. However, ICC lambs had a rapid and marked overshoot in mean systemic arterial blood pressure from 1 to 10 min after ventilation onset, which was largely absent in PBCC lambs. ICC lambs had increased cerebrovascular injury, as indicated by reduced expression of blood-brain barrier proteins and increased cerebrovascular protein leakage in the subcortical white matter (by 86%) and grey matter (by 47%). CONCLUSION: PBCC restored cardiac output and oxygenation in an identical time frame as ICC, but greatly mitigated the postasphyxia rebound hypertension measured in ICC lambs. This likely protected the asphyxiated brain from cerebrovascular injury. PBCC may be a more suitable option for the resuscitation of the asphyxiated newborn compared with the current standard of ICC.

PMID- 29191814 TI - Individual and partnership factors associated with anticipated versus actual partner notification following STI diagnosis among men who have sex with men and/or with transgender women in Lima, Peru. AB - OBJECTIVES: A detailed understanding of intentions and practices related to partner notification (PN) following STI diagnosis can improve control strategies. We assessed participant-level and partner-level factors guiding notification behaviour among men who have sex with men and/or with transgender women (MSM-TW) in Lima, Peru, including discordances between anticipated and actual notification. METHODS: Men newly diagnosed with gonorrhoea, chlamydia and/or syphilis between 2012 and 2014 reported recent partners' characteristics, anticipated PN practices, and actual PN outcomes following diagnosis. Generalised estimating equation Poisson regression analyses assessed factors guiding PN outcomes. RESULTS: Participants (n=150) predominantly identified as homosexual (70%) and moderno (versatile sexual role, 55%); 55% of partners (n=402) were casual. Among all sexual partners, 35% were notified of the STI diagnosis, though only 51% of predicted PN occurred and 26% of actual notifications were unanticipated. 47% of participants notified no partners, while 24% notified all partners. PN was more common with stable versus casual (adjusted prevalence ratio (aPR), 95% CI: 0.53, 0.39 to 0.73) or commercial (aPR, 95% CI: 0.38, 0.12 to 1.21) partners, and among participants who perceived PN as normative among their peers (aPR, 95% CI: 1.96, 1.37 to 2.82). A trend towards greater notification following condom-protected intercourse was observed (aPR, 95% CI: 1.33, 0.98 to 1.81). PN frequency did not differ by type of STI diagnosed.Anticipated notification predicted actual notification (aPR, 95% CI: 1.67, 1.19 to 2.33) only imperfectly: 81 (54%) participants' PN practices did not match their anticipated behaviour. Successful notification despite anticipated silence (40 participants, 63 partners) was associated with stable partnerships and a normative perception of PN. Non-notification despite intention (43 participants, 73 partners) frequently occurred among participants reporting exclusively oral sex with the partner or with partners identified as activo (insertive role). CONCLUSIONS: Anticipated notification imperfectly reflects actual PN behaviour. Future interventions to improve PN among MSM-TW in Peru need to acknowledge partnership contexts.

PMID- 29191815 TI - Sexual relationships, intimate partner violence and STI partner notification in Cape Town, South Africa: an observational study. AB - OBJECTIVES: We aimed to identify individual and sexual partnership characteristics associated with partner notification (PN) among people with STI. We hypothesised that PN would be less likely in more casual sexual partnerships and in partnerships with intimate partner violence (IPV). METHODS: We conducted an observational study among the first 330 patients with STI enrolled in a trial of a behavioural intervention to reduce STI incidence, at a clinic in a poor, Cape Town community. We included 195 index patients (those reporting STI symptoms), and conducted longitudinal analyses using participant-completed questionnaires on the day of diagnosis and 2 weeks later. Using partnership data for five recent sexual partners, we assessed factors associated with reported PN with logistic regressions, adjusting for repeated measurements on the same participant for each partner. RESULTS: The sample included 99 males with 303 partners and 96 females with 158 partners. Males reported perpetrating IPV in 46.2% of partnerships. Females reported being IPV victims in 53.2% of partnerships. Males notified 58.1%, females 75.4% of partners during the 2 weeks following diagnosis. Type of partner was an independent correlate of PN for males and females, with the odds of PN lower in more casual partnerships. For males, reporting physical IPV perpetration in the partnership was an independent correlate of PN. For females, there was no association between IPV victimisation in a partnership and PN. CONCLUSIONS: Efforts to decrease the pool of infectious partners need to have a strong focus on the promotion of PN in casual relationships and one-night stands. IPV was not identified as a barrier to PN. In future, we need to investigate the association between IPV with an objective measure of PN success such as partner testing or treatment, or index patient reinfection.

PMID- 29191816 TI - Clinical factors associated with syphilis concordance in men in sexual partnerships: a cross-sectional couples study. AB - BACKGROUND: Syphilis infections continue to increase among men who have sex with men (MSM) in many countries, with rates often higher among HIV-positive MSM. There is limited understanding of the risk and determinants of syphilis transmission between men. We aimed to examine the concordance of early syphilis infection between male sexual partners and clinical factors associated with transmission. METHODS: Men attending Melbourne Sexual Health Centre with their male partners, where at least one was diagnosed with early syphilis, were identified from linkage of partner records between March 2011 and April 2016. Early latent syphilis was defined as a new asymptomatic syphilis presentation of less than 2 years' duration. Associations between concordance and potential risk factors were examined using Fisher's exact test. RESULTS: Among 43 couples (86 men) identified, there were 13 couples (26 men) where both were diagnosed with early syphilis, representing a concordance rate of 30.2% (95% CI 17.2% to 46.1%). Among the 13 concordant couples, 5 men had primary syphilis (4 penile, 1 anal), 11 secondary syphilis (8 generalised rash, 3 penile, 2 anal, 1 oral lesion) and 10 early latent infections. Concordance was higher among couples where at least one partner had secondary syphilis compared with couples where neither partner had secondary syphilis (53% (9/17) vs 15% (4/26), P=0.016). Furthermore, concordance was higher among couples where one was HIV positive compared with couples where both were HIV negative (62% (5/8) vs 23% (8/35), P=0.042). CONCLUSIONS: There was an overall concordance rate of 30%. Higher concordance rates for early syphilis infection between male sexual partners were associated with HIV and secondary syphilis. PMID- 29191818 TI - Sterol 27-hydroxylase gene dosage and the antiatherosclerotic effect of Rifampicin in mice. AB - Sterol 27-hydroxylase (CYP27A1) catalyzes the hydroxylation of cholesterol to 27 hydroxycholesterol (27-OHC) and regulates cholesterol homeostasis. In Cyp27a1/ Apolipoprotein E (ApoE) double knockout (KO) mice fed with Western diet (WD), the atherosclerotic phenotype found in ApoE KO mice was reversed. As protective mechanism, up-regulation of Cyp3a11 and Cyp7a1 was proposed. Cyp27a1 heterozygote/ApoE KO (het) mice, with reduced Cyp27a1 expression and normal levels of Cyp7a1 and Cyp3a11, developed more severe lesions than ApoE KO mice. To analyze the contribution of Cyp3a11 to the protection of atherosclerosis development, Cyp3a11 was induced by Rifampicin (RIF) in ApoE KO and het mice. Males were fed with WD and treated daily with RIF (10 mg/kg ip) or vehicle for 4 weeks. Atherosclerosis was quantified in the aortic valve. Plasma lipids and 27 hydroxycholesterol (27-OHC), expression of cytochromes P450 and genes involved in cholesterol transport and bile acids (BAs) signaling in liver and intestine, and intestinal cholesterol absorption were analyzed. RIF increased expression of hepatic but not intestinal Cyp3a11 4-fold in both genotypes. In ApoE KO mice treated with RIF, we found a 2-fold decrease in plasma cholesterol, and a 2-fold increase in high-density lipoprotein/low-density lipoprotein ratio and CY27A1 activity. Intestinal cholesterol absorption remained unchanged and atherosclerotic lesions decreased approximately 3-fold. In het mice, RIF had no effect on plasma lipids composition, CYP27A1 activity, and atherosclerotic plaque development, despite a reduction in cholesterol absorption. In conclusion, the antiatherogenic effect of Cyp3a11 induction by RIF was also dependent on Cyp27a1 expression. PMID- 29191819 TI - Efficacy and safety of tocilizumab in patients with refractory Takayasu arteritis: results from a randomised, double-blind, placebo-controlled, phase 3 trial in Japan (the TAKT study). AB - OBJECTIVE: To investigate the efficacy and safety of the interleukin-6 receptor antibody tocilizumab in patients with Takayasu arteritis (TAK). METHODS: Patients with TAK who had relapsed within the previous 12 weeks were induced into remission with oral glucocorticoid therapy. In this double-blind, placebo controlled trial, patients were randomly assigned 1:1 to receive weekly tocilizumab 162 mg or placebo subcutaneously, and oral glucocorticoids were tapered 10 %/week from week 4 to a minimum of 0.1 mg/kg/day until 19 patients relapsed. The primary endpoint was time to relapse of TAK, defined as >=2 of the following: objective systemic symptoms, subjective systemic symptoms, elevated inflammation markers, vascular signs and symptoms or ischaemic symptoms. RESULTS: The intent-to-treat and safety populations included 18 tocilizumab-treated and 18 placebo-treated patients. The per-protocol set (PPS) included 16 tocilizumab treated and 17 placebo-treated patients. HRs for time to relapse of TAK were 0.41 (95.41% CI 0.15 to 1.10; p=0.0596) in the intent-to-treat population (primary endpoint) based on relapse in eight tocilizumab-treated and 11 placebo-treated patients and 0.34 (95.41% CI 0.11 to 1.00; p=0.0345) in the PPS. The secondary endpoints, time to relapse assessed by Kerr's definition and clinical symptoms only, were consistent with the primary endpoint. Serious adverse events were reported in one tocilizumab-treated and two placebo-treated patients. There were no serious infections and no deaths. CONCLUSION: Although the primary endpoint was not met, the results suggest favour for tocilizumab over placebo for time to relapse of TAK without new safety concerns. Further investigation is warranted to confirm the efficacy of tocilizumab in patients with refractory TAK. TRIAL REGISTRATION NUMBER: JapicCTI-142616. PMID- 29191821 TI - Follicular bronchiolitis in an HIV-infected individual on combination antiretroviral therapy with low CD4+ cell count but sustained viral suppression. AB - A 36-year-old Danish man, living in Asia, was diagnosed with Pneumocystis pneumonia (PCP) and HIV in 2013 (CD4+ count: 6 cells/uL; viral load: 518 000 copies/mL). He initiated combination antiretroviral therapy. Later that year, he was also diagnosed with granulomatosis with polyangiitis and was treated with prednisolone. Despite complete viral suppression and increasing CD4+ count (162 cells/uL), he was readmitted with PCP in April 2015. Subsequently, he returned to Denmark (CD4+ count: 80 cells/uL, viral suppression). Over the following months, he developed progressive dyspnoea. Lung function tests demonstrated severely reduced lung capacity with an obstructive pattern and a moderately reduced diffusion capacity. High resolution computer tomography revealed minor areas with tree-in-bud pattern and no signs of air trapping on expiratory views. Lung biopsy showed lymphocytic infiltration surrounding the bronchioles with sparing of the alveolar septa. He was diagnosed with follicular bronchiolitis. The patient spontaneously recovered along with an improvement of the immune system. PMID- 29191820 TI - Monocyte alterations in rheumatoid arthritis are dominated by preterm release from bone marrow and prominent triggering in the joint. AB - OBJECTIVE: Rheumatoid arthritis (RA) accompanies infiltration and activation of monocytes in inflamed joints. We investigated dominant alterations of RA monocytes in bone marrow (BM), blood and inflamed joints. METHODS: CD14+ cells from BM and peripheral blood (PB) of patients with RA and osteoarthritis (OA) were profiled with GeneChip microarrays. Detailed functional analysis was performed with reference transcriptomes of BM precursors, monocyte blood subsets, monocyte activation and mobilisation. Cytometric profiling determined monocyte subsets of CD14++CD16-, CD14++CD16+ and CD14+CD16+ cells in BM, PB and synovial fluid (SF) and ELISAs quantified the release of activation markers into SF and serum. RESULTS: Investigation of genes differentially expressed between RA and OA monocytes with reference transcriptomes revealed gene patterns of early myeloid precursors in RA-BM and late myeloid precursors along with reduced terminal differentiation to CD14+CD16+monocytes in RA-PB. Patterns associated with tumor necrosis factor/lipopolysaccharide (TNF/LPS) stimulation were weak and more pronounced in RA-PB than RA-BM. Cytometric phenotyping of cells in BM, blood and SF disclosed differences related to monocyte subsets and confirmed the reduced frequency of terminally differentiated CD14+CD16+monocytes in RA-PB. Monocyte activation in SF was characterised by the predominance of CD14++CD16++CD163+HLA DR+ cells and elevated concentrations of sCD14, sCD163 and S100P. CONCLUSION: Patterns of less mature and less differentiated RA-BM and RA-PB monocytes suggest increased turnover with accelerated monocytopoiesis, BM egress and migration into inflamed joints. Predominant activation in the joint indicates the action of local and primary stimuli, which may also promote adaptive immune triggering through monocytes, potentially leading to new diagnostic and therapeutic strategies.

PMID- 29191822 TI - Systemic thrombolysis in a patient with massive pulmonary embolism and recent glioblastoma multiforme resection. AB - While trials of systemic thrombolysis for submassive and massive pulmonary embolism (PE) report intracranial haemorrhage (ICH) rates of 2%-3%, the risk of ICH in patients with recent brain surgery or intracranial neoplasm is unknown since these patients were excluded from these trials. We report a case of massive PE treated with systemic thrombolysis in a patient with recent neurosurgery for an intracranial neoplasm. We discuss the risks and benefits of systemic thrombolysis for massive PE in the context of previous case reports, prior cohort studies and trials, and current guidelines. There may be times when the immediate risk of death from massive PE outweighs the risk of ICH from systemic thrombolysis, even when guideline-listed major contraindications exist. This case provides an example of how the haemodynamic benefit of systemic thrombolysis outweighed the impact of ICH in a patient who had undergone recent neurosurgical resection of a glioblastoma multiforme tumour.

AB - Rupture of fetal membranes (ROM) can initiate parturition at both term and preterm. Collagen III in the compact layer of the amnion contributes to the tensile strength of fetal membranes. However, the upstream signals triggering collagen III degradation remain mostly elusive. In this study, we investigated the role of cortisol regenerated by 11beta-hydroxysteroid dehydrogenase 1 (11beta HSD1) in collagen III degradation in human amnion fibroblasts with an aim to seek novel targets for the prevention of preterm premature ROM (pPROM)-elicited preterm birth. Human amnion tissue and cultured amnion tissue explants and amnion fibroblasts were used to study the regulation of collagen III, which is composed of three identical 3alpha 1 chains (COL3A1), by cortisol. Cortisol decreased COL3A1 protein but not mRNA abundance in a concentration-dependent manner. Cortisone also decreased COL3A1 protein, which was blocked by 11beta-HSD1 inhibition. The reduction in COL3A1 protein by cortisol was not affected by a transcription inhibitor but was further enhanced by a translation inhibitor. Autophagic pathway inhibitor chloroquine or siRNA-mediated knock-down of ATG7, an essential protein for autophagy, failed to block cortisol-induced reduction in COL3A1 protein abundance, whereas proteasome pathway inhibitors MG132 and bortezomib significantly attenuated cortisol-induced reduction in COL3A1 protein abundance. Moreover, cortisol increased COL3A1 ubiquitination and the reduction of COL3A1 protein by cortisol was blocked by PYR-41, a ubiquitin-activating enzyme inhibitor. Conclusively, cortisol regenerated in amnion fibroblasts may be associated with ROM at parturition by reducing collagen III protein abundance through a ubiquitin-proteasome pathway.

AB - In lipoxygenases, the topologically conserved C-terminal domain catalyzes the oxidation of polyunsaturated fatty acids, generating an assortment of biologically relevant signaling mediators. Plant and animal lipoxygenases also contain a 100-150-amino acid N-terminal C2-like domain that has been implicated in interactions with isolated fatty acids and at the phospholipid bilayer. These interactions may lead to increased substrate availability and contribute to the regulation of active-site catalysis. Because of a lack of structural information, a molecular understanding of this lipid-protein interaction remains unresolved. Herein, we employed hydrogen-deuterium exchange MS (HDXMS) to spatially resolve changes in protein conformation upon interaction of soybean lipoxygenase with a fatty acid surrogate, oleyl sulfate (OS), previously shown to act at a site separate from the substrate-binding site. Specific, OS-induced conformational changes are detected both at the N-terminal domain and within the substrate portal nearly 30 A away. Combining previously measured kinetic properties in the presence of OS with its impact on the Kd for linoleic acid substrate binding, we conclude that OS binding brings about an increase in rate constants for both the ingress and egress of substrate. We discuss the role of OS-induced changes in protein flexibility in the context of changes in the mechanism of substrate acquisition.

AB - Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with a poor prognosis. Gemcitabine, as a single agent or in combination therapy, remains the frontline chemotherapy despite its limited efficacy due to de novo or acquired chemoresistance. There is an acute need to decipher mechanisms underlying chemoresistance and identify new targets to improve patient outcomes. Here, we report a novel role for the ST6Gal-I sialyltransferase in gemcitabine resistance. Utilizing MiaPaCa-2 and BxPC-3 PDAC cells, we found that knockdown (KD) of ST6Gal I expression, as well as removal of surface alpha2-6 sialic acids by neuraminidase, enhances gemcitabine-mediated cell death assessed via clonogenic assays and cleaved caspase 3 expression. Additionally, KD of ST6Gal-I potentiates gemcitabine-induced DNA damage as measured by comet assays and quantification of gammaH2AX foci. ST6Gal-I KD also alters mRNA expression of key gemcitabine metabolic genes, RRM1, RRM2, hENT1, and DCK, leading to an increased gemcitabine sensitivity ratio, an indicator of gemcitabine toxicity. Gemcitabine-resistant MiaPaCa-2 cells display higher ST6Gal-I levels than treatment-naive cells along with a reduced gemcitabine sensitivity ratio, suggesting that chronic chemotherapy selects for clonal variants with more abundant ST6Gal-I. Finally, we examined Suit2 PDAC cells and Suit2 derivatives with enhanced metastatic potential. Intriguingly, three metastatic and chemoresistant subclones, S2-CP9, S2-LM7AA, and S2-013, exhibit up-regulated ST6Gal-I relative to parental Suit2 cells. ST6Gal-I KD in S2-013 cells increases gemcitabine-mediated DNA damage, indicating that suppressing ST6Gal-I activity sensitizes inherently resistant cells to gemcitabine. Together, these findings place ST6Gal-I as a critical player in imparting gemcitabine resistance and as a potential target to restore PDAC chemoresponse. PMID- 29191830 TI - Lipoic acid metabolism and mitochondrial redox regulation. AB - Lipoic acid is an essential cofactor for mitochondrial metabolism and is synthesized de novo using intermediates from mitochondrial fatty-acid synthesis type II, S-adenosylmethionine and iron-sulfur clusters. This cofactor is required for catalysis by multiple mitochondrial 2-ketoacid dehydrogenase complexes, including pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase, and branched chain ketoacid dehydrogenase. Lipoic acid also plays a critical role in stabilizing and regulating these multienzyme complexes. Many of these dehydrogenases are regulated by reactive oxygen species, mediated through the disulfide bond of the prosthetic lipoyl moiety. Collectively, its functions explain why lipoic acid is required for cell growth, mitochondrial activity, and coordination of fuel metabolism. PMID- 29191831 TI - Structural features of alpha-synuclein amyloid fibrils revealed by Raman spectroscopy. AB - Parkinson's disease (PD) is associated with the formation of alpha-synuclein amyloid fibrils. Elucidating the role of these beta-sheet-rich fibrils in disease progression is crucial; however, collecting detailed structural information on amyloids is inherently difficult because of their insoluble, non-crystalline, and polymorphic nature. Here, we show that Raman spectroscopy is a facile technique for characterizing structural features of alpha-synuclein fibrils. Combining Raman spectroscopy with aggregation kinetics and transmission electron microscopy, we examined the effects of pH and ionic strength as well as four PD related mutations (A30P, E46K, G51D, and A53T) on alpha-synuclein fibrils. Raman spectral differences were observed in the amide-I, amide-III, and fingerprint regions, indicating that secondary structure and tertiary contacts are influenced by pH and to a lesser extent by NaCl. Faster aggregation times appear to facilitate unique fibril structure as determined by the highly reproducible amide I band widths, linking aggregation propensity and fibril polymorphism. Importantly, Raman spectroscopy revealed molecular-level perturbations of fibril conformation by the PD-related mutations that are not apparent through transmission electron microscopy or limited proteolysis. The amide-III band was found to be particularly sensitive, with G51D exhibiting the most distinctive features, followed by A53T and E46K. Relating to a cellular environment, our data would suggest that fibril polymorphs can be formed in different cellular compartments and potentially result in distinct phenotypes. Our work sets a foundation toward future cellular Raman studies of amyloids. PMID- 29191832 TI - Molecular characterization of human anti-hinge antibodies derived from single cell cloning of normal human B cells. AB - Anti-hinge antibodies (AHAs) are an autoantibody subclass that, following proteolytic cleavage, recognize cryptic epitopes exposed in the hinge regions of immunoglobulins (Igs) and do not bind to the intact Ig counterpart. AHAs have been postulated to exacerbate chronic inflammatory disorders such as inflammatory bowel disease and rheumatoid arthritis. On the other hand, AHAs may protect against invasive microbial pathogens and cancer. However, despite more than 50 years of study, the origin and specific B cell compartments that express AHAs remain elusive. Recent research on serum AHAs suggests that they arise during an active immune response, in contrast to previous proposals that they derive from the preexisting immune repertoire in the absence of antigenic stimuli. We report here the isolation and characterization of AHAs from memory B cells, although anti-hinge-reactive B cells were also detected in the naive B cell compartment. IgG AHAs cloned from a single human donor exhibited restricted specificity for protease-cleaved F(ab')2 fragments and did not bind the intact IgG counterpart. The cloned IgG-specific AHA-variable regions were mutated from germ line-derived sequences and displayed a high sequence variability, confirming that these AHAs underwent class-switch recombination and somatic hypermutation. Consistent with previous studies of serum AHAs, several of these clones recognized a linear, peptide-like epitope, but one clone was unique in recognizing a conformational epitope. All cloned AHAs could restore immune effector functions to proteolytically generated F(ab')2 fragments. Our results confirm that a diverse set of epitope-specific AHAs can be isolated from a single human donor. PMID- 29191833 TI - Autophagy and disease. AB - As outlined in the accompanying Minireviews, autophagy is a complicated and highly regulated process that delivers cellular material to lysosomes for degrading, recycling, and generating molecules that fuel cellular metabolism. Autophagy is important for normal cellular and organismal physiology, and both increased and decreased autophagy has been associated with disease. Importantly, these connections are already being exploited to treat patients with dozens of clinical trials that aim to manipulate autophagy to treat (or prevent) disease. This Minireview discusses some of the important issues and problems to be solved if these efforts are to be successful. PMID- 29191834 TI - Three mammalian tropomyosin isoforms have different regulatory effects on nonmuscle myosin-2B and filamentous beta-actin in vitro. AB - The metazoan actin cytoskeleton supports a wide range of contractile and transport processes. Recent studies have shown how the dynamic association with specific tropomyosin isoforms generates actin filament populations with distinct functional properties. However, critical details of the associated molecular interactions remain unclear. Here, we report the properties of actomyosin tropomyosin complexes containing filamentous beta-actin, nonmuscle myosin-2B (NM 2B) constructs, and either tropomyosin isoform Tpm1.8cy (b.-.b.d), Tpm1.12br (b. .b.c), or Tpm3.1cy (b.-.a.d). Our results show the extent to which the association of filamentous beta-actin with these different tropomyosin cofilaments affects the actin-mediated activation of NM-2B and the release of the ATP hydrolysis products ADP and phosphate from the active site. Phosphate release gates a transition from weak to strong F-actin-binding states. The release of ADP has the opposite effect. These changes in dominant rate-limiting steps have a direct effect on the duty ratio, the fraction of time that NM-2B spends in strongly F-actin-bound states during ATP turnover. The duty ratio is increased ~3 fold in the presence of Tpm1.12 and 5-fold for both Tpm1.8 and Tpm3.1. The presence of Tpm1.12 extends the time required per ATP hydrolysis cycle 3.7-fold, whereas it is shortened by 27 and 63% in the presence of Tpm1.8 and Tpm3.1, respectively. The resulting Tpm isoform-specific changes in the frequency, duration, and efficiency of actomyosin interactions establish a molecular basis for the ability of these complexes to support cellular processes with widely divergent demands in regard to force production, capacity to move processively, and speed of movement. PMID- 29191835 TI - Phosphorylation of human enhancer filamentation 1 (HEF1) stimulates interaction with Polo-like kinase 1 leading to HEF1 localization to focal adhesions. AB - Elevated expression of human enhancer filamentation 1 (HEF1; also known as NEDD9 or Cas-L) is an essential stimulus for the metastatic process of various solid tumors. This process requires HEF1 localization to focal adhesions (FAs). Although the association of HEF1 with FAs is considered to play a role in cancer cell migration, the mechanism targeting HEF1 to FAs remains unclear. Moreover, up regulation of Polo-like kinase 1 (Plk1) positively correlates with human cancer metastasis, yet how Plk1 deregulation promotes metastasis remains elusive. Here, we report that casein kinase 1delta (CK1delta) phosphorylates HEF1 at Ser-780 and Thr-804 and that these phosphorylation events promote a physical interaction between Plk1 and HEF1. We found that this interaction is critical for HEF1 translocation to FAs and for inducing migration of HeLa cells. Plk1-docking phosphoepitopes were mapped/confirmed in HEF1 by various methods, including X-ray crystallography, and mutated for functional analysis in HeLa cells. In summary, our results reveal the role of a phosphorylation-dependent HEF1-Plk1 complex in HEF1 translocation to FAs to induce cell migration. Our findings provide critical mechanistic insights into the HEF1-Plk1 complex-dependent localization of HEF1 to FAs underlying the metastatic process and may therefore contribute to the development of new cancer therapies. PMID- 29191836 TI - Steady-state analysis of enzymes with non-Michaelis-Menten kinetics: The transport mechanism of Na+/K+-ATPase. AB - Procedures to define kinetic mechanisms from catalytic activity measurements that obey the Michaelis-Menten equation are well established. In contrast, analytical tools for enzymes displaying non-Michaelis-Menten kinetics are underdeveloped, and transient-state measurements, when feasible, are therefore preferred in kinetic studies. Of note, transient-state determinations evaluate only partial reactions, and these might not participate in the reaction cycle. Here, we provide a general procedure to characterize kinetic mechanisms from steady-state determinations. We described non-Michaelis-Menten kinetics with equations containing parameters equivalent to kcat and Km and modeled the underlying mechanism by an approach similar to that used under Michaelis-Menten kinetics. The procedure enabled us to evaluate whether Na+/K+-ATPase uses the same sites to alternatively transport Na+ and K+ This ping-pong mechanism is supported by transient-state studies but contradicted to date by steady-state analyses claiming that the release of one cationic species as product requires the binding of the other (ternary-complex mechanism). To derive robust conclusions about the Na+/K+-ATPase transport mechanism, we did not rely on ATPase activity measurements alone. During the catalytic cycle, the transported cations become transitorily occluded (i.e. trapped within the enzyme). We employed radioactive isotopes to quantify occluded cations under steady-state conditions. We replaced K+ with Rb+ because 42K+ has a short half-life, and previous studies showed that K+- and Rb+-occluded reaction intermediates are similar. We derived conclusions regarding the rate of Rb+ deocclusion that were verified by direct measurements. Our results validated the ping-pong mechanism and proved that Rb+ deocclusion is accelerated when Na+ binds to an allosteric, nonspecific site, leading to a 2 fold increase in ATPase activity.

PMID- 29191837 TI - Age-dependent increase in angiopoietin-like protein 2 accelerates skeletal muscle loss in mice. AB - Skeletal muscle atrophy, or sarcopenia, is commonly observed in older individuals and in those with chronic disease and is associated with decreased quality of life. There is recent medical and broad concern that sarcopenia is rapidly increasing worldwide as populations age. At present, strength training is the only effective intervention for preventing sarcopenia development, but it is not known how this exercise regimen counteracts this condition. Here, we report that expression of the inflammatory mediator angiopoietin-like protein 2 (ANGPTL2) increases in skeletal muscle of aging mice. Moreover, in addition to exhibiting increased inflammation and accumulation of reactive oxygen species (ROS), denervated atrophic skeletal muscles in a mouse model of denervation-induced muscle atrophy had increased ANGPTL2 expression. Interestingly, mice with a skeletal myocyte-specific Angptl2 knockout had attenuated inflammation and ROS accumulation in denervated skeletal muscle, accompanied by increased satellite cell activity and inhibition of muscular atrophy compared with mice harboring wildtype Angptl2 Moreover, consistent with these phenotypes, wildtype mice undergoing exercise training displayed decreased ANGPTL2 expression in skeletal muscle. In conclusion, ANGPTL2 up-regulation in skeletal myocytes accelerates muscle atrophy, and exercise-induced attenuation of ANGPTL2 expression in those tissues may partially explain how exercise training prevents sarcopenia.

PMID- 29191842 TI - Targeting the anion exchanger 2 with specific peptides as a new therapeutic approach in B lymphoid neoplasms. AB - Regulatory T (Treg) cells can weaken antitumor immune responses, and inhibition of their function appears to be a promising therapeutic approach in cancer patients. Mice with targeted deletion of the gene encoding the Cl-/HCO3- anion exchanger AE2 (also termed SLC4A2), a membrane-bound carrier involved in intracellular pH regulation, showed a progressive decrease in the number of Treg cells. We therefore challenged AE2 as a potential target for tumor therapy, and generated linear peptides designed to bind the third extracellular loop of AE2, which is crucial for its exchange activity. Peptide p17AE2 exhibited optimal interaction ability and indeed promoted apoptosis in mouse and human Treg cells, while activating effector T-cell function. Interestingly, this linear peptide also induced apoptosis in different types of human leukemia, lymphoma and multiple myeloma cell lines and primary malignant samples, while it showed only moderate effects on normal B lymphocytes. Finally, a macrocyclic AE2 targeting peptide exhibiting increased stability in vivo was effective in mice xenografted with B-cell lymphoma. These data suggest that targeting the anion exchanger AE2 with specific peptides may represent an effective therapeutic approach in B-cell malignancies. PMID- 29191844 TI - Reduction in Hypoglycemia With the Predictive Low-Glucose Management System: A Long-term Randomized Controlled Trial in Adolescents With Type 1 Diabetes. AB - OBJECTIVE: Short-term studies with automated systems that suspend basal insulin when hypoglycemia is predicted have shown a reduction in hypoglycemia; however, efficacy and safety have not been established in long-term trials. RESEARCH DESIGN AND METHODS: We conducted a 6-month, multicenter, randomized controlled trial in children and adolescents with type 1 diabetes using the Medtronic MiniMed 640G pump with Suspend before low (predictive low-glucose management [PLGM]) compared with sensor-augmented pump therapy (SAPT) alone. The primary outcome was percentage time in hypoglycemia with sensor glucose (SG) <3.5 mmol/L (63 mg/dL). RESULTS: In an intent-to-treat analysis of 154 subjects, 74 subjects were randomized to SAPT and 80 subjects to PLGM. At baseline, the time with SG <3.5 mmol/L was 3.0% and 2.8% in the SAPT and PLGM groups, respectively. During the study, PLGM was associated with a reduction in hypoglycemia compared with SAPT (% time SG <3.5 mmol/L: SAPT vs. PLGM, 2.6 vs. 1.5, P < 0.0001). A similar effect was also noted in time with SG <3 mmol/L (P < 0.0001). This reduction was seen both during day and night (P < 0.0001). Hypoglycemic events (SG <3.5 mmol/L for >20 min) also declined with PLGM (SAPT vs. PLGM: events/patient-year 227 vs. 139, P < 0.001). There was no difference in glycated hemoglobin (HbA1c) at 6 months (SAPT 7.6 +/- 1.0% vs. PLGM 7.8 +/- 0.8%, P = 0.35). No change in quality of life measures was reported by participants/parents in either group. There were no PLGM-related serious adverse events. CONCLUSIONS: In children and adolescents with type 1 diabetes, PLGM reduced hypoglycemia without deterioration in glycemic control. PMID- 29191846 TI - Acquired triggering of the fingers and thumb in adults. PMID- 29191845 TI - Revisiting the Relationships Between Measures of Glycemic Control and Hypoglycemia in Continuous Glucose Monitoring Data Sets. AB - OBJECTIVE: The Diabetes Control and Complications Trial (DCCT) identified an inverse relationship between HbA1c and severe hypoglycemia. We investigated the relationship between hypoglycemia and HbA1c in a large type 1 diabetes cohort on multiple daily injection or insulin pump therapy using blinded continuous glucose monitoring (CGM) data. The impact of real-time CGM on these relationships and how these relationships differ with biochemical definitions of hypoglycemia have also been assessed. RESEARCH DESIGN AND METHODS: CGM data were obtained from the JDRF CGM randomized control trial. Baseline blinded CGM data were used to assess time in hypoglycemia in all individuals. End point data from the CGM intervention group were used to assess the impact of CGM. Percentage of time spent below 3.9, 3.3, 3.0, and 2.8 mmol/L were calculated and quadratic regression plots drawn. Relationships were analyzed visually, and ANOVA was used to assess relationships between glycemia and time below threshold. RESULTS: J-shaped relationships were observed for all biochemical hypoglycemia thresholds, with the lowest hypoglycemia risk occurring at HbA1c values between 8.1 and 8.6% (65-70 mmol/mol). The use of an average of 5 days/week of CGM flattened the relationships for 3.3, 3.0, and 2.8 mmol/L, and ANOVA confirmed the loss of relationship for the 3.3 mmol/L threshold using CGM. CONCLUSIONS: The relationship between hypoglycemia and HbA1c in a population with type 1 diabetes is J-shaped. Lower HbA1c values are still associated with increased hypoglycemia risk, although the magnitude of risk depends on biochemical threshold. Real-time CGM may reduce the percentage time spent in hypoglycemia, changing the relationship between HbA1c and hypoglycemia. PMID- 29191847 TI - WASP family proteins and formins compete in pseudopod- and bleb-based migration. AB - Actin pseudopods induced by SCAR/WAVE drive normal migration and chemotaxis in eukaryotic cells. Cells can also migrate using blebs, in which the edge is driven forward by hydrostatic pressure instead of actin. In Dictyostelium discoideum, loss of SCAR is compensated by WASP moving to the leading edge to generate morphologically normal pseudopods. Here we use an inducible double knockout to show that cells lacking both SCAR and WASP are unable to grow, make pseudopods or, unexpectedly, migrate using blebs. Remarkably, amounts and dynamics of actin polymerization are normal. Pseudopods are replaced in double SCAR/WASP mutants by aberrant filopods, induced by the formin dDia2. Further disruption of the gene for dDia2 restores cells' ability to initiate blebs and thus migrate, though pseudopods are still lost. Triple knockout cells still contain near-normal F actin levels. This work shows that SCAR, WASP, and dDia2 compete for actin. Loss of SCAR and WASP causes excessive dDia2 activity, maintaining F-actin levels but blocking pseudopod and bleb formation and migration. PMID- 29191849 TI - Statin Treatment in Patients With Intracerebral Hemorrhage. PMID- 29191848 TI - Keratin 6a reorganization for ubiquitin-proteasomal processing is a direct antimicrobial response. AB - Skin and mucosal epithelia deploy antimicrobial peptides (AMPs) to eliminate harmful microbes. We reported that the intermediate filament keratin 6a (K6a) is constitutively processed into antimicrobial fragments in corneal epithelial cells. In this study, we show that K6a network remodeling is a host defense response that directly up-regulates production of keratin-derived AMPs (KAMPs) by the ubiquitin-proteasome system (UPS). Bacterial ligands trigger K6a phosphorylation at S19, S22, S37, and S60, leading to network disassembly. Mutagenic analysis of K6a confirmed that the site-specific phosphorylation augmented its solubility. K6a in the cytosol is ubiquitinated by cullin-RING E3 ligases for subsequent proteasomal processing. Without an appreciable increase in K6a gene expression and proteasome activity, a higher level of cytosolic K6a results in enhanced KAMP production. Although proteasome-mediated proteolysis is known to produce antigenic peptides in adaptive immunity, our findings demonstrate its new role in producing AMPs for innate immune defense. Manipulating K6a phosphorylation or UPS activity may provide opportunities to harness the innate immunity of epithelia against infection. PMID- 29191850 TI - Long-Term Effect of Pravastatin on Carotid Intima-Media Complex Thickness: The J STARS Echo Study (Japan Statin Treatment Against Recurrent Stroke). AB - BACKGROUND AND PURPOSE: The effect of statins on progression of carotid intima media complex thickness (IMT) has been shown exclusively in nonstroke Western patients. This study aimed to determine the effect of low-dose pravastatin on carotid IMT in Japanese patients with noncardioembolic ischemic stroke. METHODS: This is a substudy of the J-STARS trial (Japan Statin Treatment Against Recurrent Stroke), a multicenter, randomized, open-label, parallel-group trial to examine whether pravastatin reduces stroke recurrence. Patients were randomized to receive pravastatin (10 mg daily, usual dose in Japan; pravastatin group) or not to receive any statins (control group). The primary outcome was IMT change of the common carotid artery for a 5-year observation period. IMT change was compared using mixed-effects models for repeated measures. RESULTS: Of 864 patients registered in this substudy, 71 without baseline ultrasonography were excluded, and 388 were randomly assigned to the pravastatin group and 405 to the control group. Baseline characteristics were not significantly different, except National Institutes of Health Stroke Scale scores (median, 0 [interquartile range, 0-2] versus 1 [interquartile range, 0-2]; P=0.019) between the 2 groups. Baseline IMT (mean+/-SD) was 0.887+/-0.155 mm in the pravastatin group and 0.887+/-0.152 mm in the control group (P=0.99). The annual change in the IMT at 5-year visit was significantly reduced in the pravastatin group as compared with that in the control group (0.021+/-0.116 versus 0.040+/-0.118 mm; P=0.010). CONCLUSIONS: The usual Japanese dose of pravastatin significantly reduced the progression of carotid IMT at 5 years in patients with noncardioembolic stroke.

AB - BACKGROUND AND PURPOSE: We aimed to study the intrarater and interrater agreement of clinicians attributing DWI-ASPECTS (Diffusion-Weighted Imaging-Alberta Stroke Program Early Computed Tomography Scores) and DWI-FLAIR (Diffusion-Weighted Imaging-Fluid Attenuated Inversion Recovery) mismatch in patients with acute ischemic stroke referred for mechanical thrombectomy. METHODS: Eighteen raters independently scored anonymized magnetic resonance imaging scans of 30 participants from a multicentre thrombectomy trial, in 2 different reading sessions. Agreement was measured using Fleiss kappa and Cohen kappa statistics. RESULTS: Interrater agreement for DWI-ASPECTS was slight (kappa=0.17 [0.14 0.21]). Four raters (22.2%) had a substantial (or higher) intrarater agreement. Dichotomization of the DWI-ASPECTS (0-5 versus 6-10 or 0-6 versus 7-10) increased the interrater agreement to a substantial level (kappa=0.62 [0.48-0.75] and 0.68 [0.55-0.79], respectively) and more raters reached a substantial (or higher) intrarater agreement (17/18 raters [94.4%]). Interrater agreement for DWI-FLAIR mismatch was moderate (kappa=0.43 [0.33-0.57]); 11 raters (61.1%) reached a substantial (or higher) intrarater agreement. CONCLUSIONS: Agreement between clinicians assessing DWI-ASPECTS and DWI-FLAIR mismatch may not be sufficient to make repeatable clinical decisions in mechanical thrombectomy. The dichotomization of the DWI-ASPECTS (0-5 versus 0-6 or 0-6 versus 7-10) improved interrater and intrarater agreement, however, its relevance for patients selection for mechanical thrombectomy needs to be validated in a randomized trial. PMID- 29191852 TI - Challenge and Yield of Enrolling Racially and Ethnically Diverse Patient Populations in Low Event Rate Clinical Trials. AB - BACKGROUND AND PURPOSE: We report patient enrollment and retention by race and ethnicity in the CREST (Carotid Revascularization Endarterectomy Versus Stent Trial) and assess potential effect modification by race/ethnicity. In addition, we discuss the challenge of detecting differences in study outcomes when subgroups are small and the event rate is low. METHODS: We compared 2502 patients by race, ethnicity, baseline characteristics, and primary outcome (any periprocedural stroke, death, or myocardial infarction and subsequent ipsilateral stroke up to 10 years). RESULTS: Two hundred forty (9.7%) patients were minority by race (6.1%) or ethnicity (3.6%); 109 patients (4.4%) were black, 32 (1.3%) Asian, 2332 (93.4%) white, 11 (0.4%) other, and 18 (0.7%) unknown. Ninety (3.6%) were Hispanic, 2377 (95%) non-Hispanic, and 35 (1.4%) unknown. The rate of the primary end point for all patients was 10.9%+/-0.9% at 10 years and did not differ by race or ethnicity (Pinter>0.24). CONCLUSIONS: The proportion of minorities recruited to CREST was below their representation in the general population, and retention of minority patients was lower than for whites. Primary outcomes did not differ by race or ethnicity. However, in CREST (like other studies), the lack of evidence of a racial/ethnic difference in the treatment effect should be interpreted with caution because of low statistical power to detect such a difference.

PMID- 29191854 TI - Intended Versus Inferred Treatment After 18F-Fluoride PET Performed for Evaluation of Osseous Metastatic Disease in the National Oncologic PET Registry. AB - We have previously reported that PET with 18F-fluoride (NaF PET) for assessment of osseous metastatic disease led to changes in intended management in a substantial fraction of patients with prostate or other types of cancer participating in the National Oncologic PET Registry. This study was performed to assess the concordance of intended patient management after NaF PET and inferred management based on analysis of Medicare claims. Methods: We analyzed linked post NaF PET data of consenting National Oncologic PET Registry participants age 65 y or older from 2011 to 2014 and their corresponding Medicare claims. Post-NaF PET treatment plans, including combinations of 2 modes of therapy, were assessed for their concordance with clinical actions inferred from Medicare claims. NaF PET studies were stratified by indication (initial staging [IS] or suspected first osseous metastasis [FOM]) and cancer type (prostate, lung, or other cancers). Agreement was assessed between post-NaF PET intended management plans for treatment (surgery, radiotherapy, or systemic therapy) within 90 d for lung and 180 d for prostate or other cancers, and for watching (the absence of treatment claims for >=60 d) as compared with claims-inferred care. Results: Actions after 9,898 scans were assessed. After NaF PET for IS, there was claims agreement for planned surgery in 76.0% (19/25) lung, 75.4% (98/130) other cancers, and 58.9% (298/506) prostate cancer. Claims confirmed chemotherapy plans after NaF PET done for IS or FOM in 81.0% and 73.5% for lung cancer (n = 148 and 136) and 69.4% and 67.5% for other cancers (n = 111 and 228). For radiotherapy plans, agreement ranged from 80.0% to 84.4% after IS and 68.4% to 74.0% for suspected FOM. Concordance was greatest for androgen deprivation therapy (ADT) (86.0%, n = 308) alone or combined with radiotherapy in prostate cancer IS (80.8%, n = 517). In prostate FOM, the concordance across all treatment plans was lower if the patients had ADT claims within 180 d before NaF PET. Agreement with nontreatment plans was high for FOM (87.2% in other cancers and 78.6% if no prior ADT in prostate) and low after IS (40.7%-62.5%). Conclusion: Concordance of post-NaF PET plans and claims was substantial and higher overall for IS than for FOM. PMID- 29191855 TI - Sensitivity Comparison of 68Ga-OPS202 and 68Ga-DOTATOC PET/CT in Patients with Gastroenteropancreatic Neuroendocrine Tumors: A Prospective Phase II Imaging Study. AB - Radiolabeled somatostatin (sst) receptor agonists are integral to the diagnosis of gastroenteropancreatic neuroendocrine tumors (NETs), but detection rates, especially of liver metastases, remain limited even with PET/CT. 68Ga-OPS202 (68Ga-NODAGA-JR11; NODAGA = 1,4,7-triazacyclononane,1-glutaric acid-4,7-acetic acid and JR11 = Cpa-c(dCys-Aph(Hor)-dAph(Cbm)-Lys-Thr-Cys)-dTyr-NH2)), a novel radiolabeled sst receptor antagonist with a high affinity for the sst2 receptor, has the potential to perform better than sst receptor agonists. Here, we present the results of the phase II component of a phase I/II study that evaluated the sensitivity of 68Ga-OPS202, compared with the reference compound, 68Ga-DOTATOC (an sst receptor agonist), in PET imaging. Methods: Patients received a single 150-MBq intravenous injection of 68Ga-DOTATOC (15 MUg of peptide) and 2 single 150-MBq intravenous injections of 68Ga-OPS202 (15 MUg of peptide at visit 1 and 50 MUg at visit 2). Whole-body PET/CT acquisitions were performed 1 h after injection on the same calibrated PET/CT scanner. Diagnostic efficacy measures were compared against contrast medium-enhanced CT or MRI as the gold standard. Two independent masked experts read the scans, and both outcomes were combined for analysis. Results: Twelve consecutive patients with low- or intermediate grade gastroenteropancreatic NETs took part in this prospective study. Image contrast for matched malignant liver lesions was significantly higher for the 68Ga-OPS202 scans than for the 68Ga-DOTATOC scan: the median of the mean tumor-to background SUVmax ratios were significantly higher for 15 and 50 MUg of 68Ga OPS202 (5.3 and 4.3, with interquartile ranges of 2.9-5.7 and 3.4-6.3 and P values of 0.004 and 0.008) than for 68Ga-DOTATOC (1.9, with an interquartile range of 1.4-2.9). The higher tumor-to-background ratio of 68Ga-OPS202 resulted not only in a higher detection rate of liver metastases but also in a significantly higher lesion-based overall sensitivity with the antagonist than with 68Ga-DOTATOC: 94% and 88% for 50 and 15 MUg of 68Ga-OPS202, respectively, and 59% for 15 MUg of 68Ga-DOTATOC (P < 0.001). Positive predictive values for 68Ga-OPS202 PET/CT and 68Ga-DOTATOC PET/CT were similar (~98%). There were no significant differences in image contrast, sensitivity, or positive predictive values between the 2 68Ga-OPS202 peptide doses, indicating a high reproducibility. Conclusion: Preliminary diagnostic efficacy data from this phase II study indicate that 68Ga-OPS202 has high sensitivity for the detection of gastroenteropancreatic NETs. Further studies in larger patient populations are warranted. PMID- 29191856 TI - PSMA-11-Derived Dual-Labeled PSMA Inhibitors for Preoperative PET Imaging and Precise Fluorescence-Guided Surgery of Prostate Cancer. AB - Resection of tumors using targeted dual-modality probes combining preoperative imaging with intraoperative guidance is of high clinical relevance and might considerably affect the outcome of prostate cancer therapy. This work aimed at the development of dual-labeled prostate-specific membrane antigen (PSMA) inhibitors derived from the established N,N'-bis[2-hydroxy-5 (carboxyethyl)benzyl]ethylenediamine-N,N'-diacetic acid (HBED-CC)-based PET tracer 68Ga-Glu-urea-Lys(Ahx)-HBED-CC (68Ga-PSMA-11) to allow accurate intraoperative detection of PSMA-positive tumors. Methods: A series of novel PSMA targeting fluorescent dye conjugates of Glu-urea-Lys-HBED-CC was synthesized, and their biologic properties were determined in cell-based assays and confocal microscopy. As a preclinical proof of concept, specific tumor uptake, pharmacokinetics, and feasibility for intraoperative fluorescence guidance were investigated in tumor-bearing mice and healthy pigs. Results: The designed dual labeled PSMA inhibitors exhibited high binding affinity and PSMA-specific effective internalization. Conjugation of fluorescein isothiocyanate (10.86 +/- 0.94 percentage injected dose [%ID]/g), IRDye800CW (13.66 +/- 3.73 %ID/g), and DyLight800 (15.62 +/- 5.52 %ID/g) resulted in a significantly increased specific tumor uptake, whereas 68Ga-Glu-urea-Lys-HBED-CC-AlexaFluor488 (9.12 +/- 5.47 %ID/g) revealed a tumor uptake similar to that of 68Ga-PSMA-11 (4.89 +/- 1.34 %ID/g). The first proof-of-concept studies with the clinically relevant candidate 68Ga-Glu-urea-Lys-HBED-CC-IRDye800CW reinforced a fast, specific enrichment in PSMA-positive tumors, with rapid background clearance. With regard to intraoperative navigation, a specific fluorescence signal was detected in PSMA expressing tissue. Conclusion: This study demonstrated that PSMA-11-derived dual labeled dye conjugates are feasible for providing PSMA-specific pre-, intra-, and postoperative detection of prostate cancer lesions and have high potential for future clinical translation. PMID- 29191857 TI - Evaluation of 11C-Me-NB1 as a Potential PET Radioligand for Measuring GluN2B Containing NMDA Receptors, Drug Occupancy, and Receptor Cross Talk. AB - Clinical and preclinical research with modulators at the N-methyl-d-aspartate (NMDA) receptor GluN2B N-terminal domain (NTD) aims for the treatment of various neurologic diseases. The interpretation of the results is hampered by the lack of a suitable NMDA PET tracer for assessing the receptor occupancy of potential drugs. We have developed 11C-Me-NB1 as a PET tracer for imaging GluN1/GluN2B containing NMDA receptors and used it to investigate in rats the dose-dependent receptor occupancy of eliprodil, a GluN2B NTD modulator. Methods:11C-Me-NB1 was synthesized and characterized by in vitro displacement binding experiments with rat brain membranes, in vitro autoradiography, and blocking and displacement experiments by PET and PET kinetic modeling. Receptor occupancy by eliprodil was studied by PET with 11C-Me-NB1. Results:11C-Me-NB1 was synthesized at 290 +/- 90 GBq/MUmol molar activity, 7.4 +/- 1.9 GBq total activity at the end of synthesis (n = 17), and more than 99% radiochemical purity. 11C-Me-NB1 binding in rat brain was blocked in vitro and in vivo by the NTD modulators Ro-25-6981 and eliprodil. Half-maximal receptor occupancy by eliprodil occurred at 1.5 MUg/kg. At 1 mg/kg of eliprodil, a dose with reported neuroprotective effects, more than 99.5% of binding sites were occupied. In vitro, 11C-Me-NB1 binding was independent of the sigma-1 receptor (Sigma1R), and the Sigma1R agonist (+)-pentazocine did not compete for high-affinity binding. In vivo, a 2.5 mg/kg dose of (+)-pentazocine abolished 11C-Me-NB1-specific binding, indicating an indirect effect of Sigma1R on 11C-Me-NB1 binding. Conclusion:11C-Me-NB1 is suitable for the in vivo imaging of NMDA GluN1/GluN2B receptors and the assessment of receptor occupancy by NTD modulators. GluN1/GluN2B NMDA receptors are fully occupied at neuroprotective doses of eliprodil. Furthermore, 11C-Me-NB1 enables imaging of GluN1/GluN2B NMDA receptor cross talk. PMID- 29191858 TI - Flortaucipir F 18 Quantitation Using Parametric Estimation of Reference Signal Intensity. AB - PET imaging of tau pathology in Alzheimer disease may benefit from the use of white matter reference regions. These regions have shown reduced variability compared with conventional cerebellar regions in amyloid imaging. However, they are susceptible to contamination from partial-volume blurring of tracer uptake in the cortex. We present a new technique, PERSI (Parametric Estimation of Reference Signal Intensity), for flortaucipir F 18 count normalization that leverages the advantages of white matter reference regions while mitigating potential partial volume effects. Methods: Subjects with a clinical diagnosis of Alzheimer disease, mild cognitive impairment, or normal cognition underwent T1-weighted MRI and florbetapir imaging (to determine amyloid [Abeta] status) at screening and flortaucipir F 18 imaging at single or multiple time points. Flortaucipir F 18 images, acquired as 4 * 5 min frames 80 min after a 370-MBq injection, were motion-corrected, averaged, and transformed to Montreal Neurological Institute (MNI) space. The PERSI reference region was calculated for each scan by fitting a bimodal gaussian distribution to the voxel-intensity histogram within an atlas based white matter region and using the center and width of the lower-intensity peak to identify the voxel intensities to be included. Four conventional reference regions were also evaluated: whole cerebellum, cerebellar gray matter, atlas-based white matter, and subject-specific white matter. SUVr (standardized uptake value ratio) was calculated for a statistically defined neocortical volume of interest. Performance was evaluated with respect to test-retest variability in a phase 2 study of 21 subjects (5-34 d between scans). Baseline variability in controls (SD of SUVr and DeltaSUVr) and effect sizes for group differences (Cohen d; Abeta-positive impaired vs. Abeta-negative normal) were evaluated in another phase 2 study with cross-sectional data (n = 215) and longitudinal data (n = 142/215; 18 +/- 2 mo between scans). Results: PERSI showed superior test-retest reproducibility (1.84%) and group separation ability (cross-sectional Cohen d = 9.45; longitudinal Cohen d = 2.34) compared with other reference regions. Baseline SUVr variability and DeltaSUVr were minimal in Abeta control subjects with no specific flortaucipir F 18 uptake (SUVr, 1.0 +/- 0.04; DeltaSUVr, 0.0 +/- 0.02). Conclusion: PERSI reduced variability while enhancing discrimination between diagnostic cohorts. Such improvements could lead to more accurate disease staging and robust measurements of changes in tau burden over time for the evaluation of putative therapies. PMID- 29191859 TI - Swim and fly: escape strategy in neustonic and planktonic copepods. AB - Copepods can respond to predators by powerful escape jumps that in some surface dwelling forms may propel the copepod out of the water. We studied the kinematics and energetics of submerged and out-of-water jumps of two neustonic pontellid copepods, Anomalocera patersoni and Pontella mediterranea, and one pelagic calanoid copepod, Calanus helgolandicus (euxinus). We show that jumping out of the water does not happen just by inertia gained during the copepod's acceleration underwater, but also requires the force generated by the thoracic limbs when breaking through the water's surface to overcome surface tension, drag and gravity. The timing of this appears to be necessary for success. At the moment of breaking the water interface, the instantaneous velocity of the two pontellids reached 125 cm s-1, while their maximum underwater speed (115 cm s-1) was close to that of similarly sized C. helgolandicus (106 cm s-1). The average specific power produced by the two pontellids during out-of-water jumps (1700 3300 W kg-1 muscle mass) was close to that during submerged jumps (900-1600 W kg 1 muscle mass) and, in turn, similar to that produced during submerged jumps of C. helgolandicus (1300 W kg-1 muscle mass). The pontellids may shake off water adhering to their body by repeated strokes of the limbs during flight, which leads to a slight acceleration in the air. Our observations suggest that out-of water jumps of pontellids are not dependent on any exceptional ability to perform this behavior but have the same energetic cost and are based on the same kinematic patterns and contractive capabilities of muscles as those of copepods swimming submerged. PMID- 29191860 TI - Hormesis-like effect of mild larval crowding on thermotolerance in Drosophila flies. AB - Crowding is a complex stress that can affect organisms' physiology, especially through decreased food quality and accessibility. Here, we evaluated the effect of larval density on several biological traits of Drosophila melanogaster An increasing gradient, from 1 to 1000 eggs per milliliter of food, was used to characterize life-history traits variations. Crowded conditions resulted in striking decreases of fresh mass (up to 6-fold) and viability, as well as delayed development. Next, we assessed heat and cold tolerance in L3 larvae reared at three selected larval densities: low (LD, 5 eggs ml-1), medium (MD, 60 eggs ml-1) and high (HD, 300 eggs ml-1). LT50 values of MD and, to a lesser extent, HD larvae were repeatedly higher than those from LD larvae, under both heat and cold stress. We investigated potential physiological correlates associated with this density-dependent thermotolerance shift. No marked pattern could be drawn from the expression of stress-related genes. However, a metabolomic analysis differentiated the metabotypes of the three density levels, with potential candidates associated with this clustering (e.g. glucose 6-phosphate, GABA, sugars and polyols). Under HD, signs of oxidative stress were noted but not confirmed at the transcriptional level. Finally, urea, a common metabolic waste, was found to accumulate substantially in food from MD and HD larvae. When supplemented in food, urea stimulated cold tolerance but reduced heat tolerance in LD larvae. This study highlights that larval crowding is an important environmental parameter that induces drastic consequences on flies' physiology and can affect thermotolerance in a density-specific way. PMID- 29191861 TI - Determining forward speed from accelerometer jiggle in aquatic environments. AB - How fast animals move is critical to understanding their energetic requirements, locomotor capacity and foraging performance, yet current methods for measuring speed via animal-attached devices are not universally applicable. Here, we present and evaluate a new method that relates forward speed to the stochastic motion of biologging devices as tag jiggle, the amplitude of the tag vibrations as measured by high sample rate accelerometers, increases exponentially with increasing speed. We successfully tested this method in a flow tank using two types of biologging devices and in situ on wild cetaceans spanning ~3 to >20 m in length using two types of suction cup-attached tag and two types of dart-attached tag. This technique provides some advantages over other approaches for determining speed as it is device-orientation independent and relies only on a pressure sensor and a high sample rate accelerometer, sensors that are nearly universal across biologging device types. PMID- 29191863 TI - Exposure to CO2 influences metabolism, calcification and gene expression of the thecosome pteropod Limacina retroversa. AB - Thecosomatous pteropods, a group of aragonite shell-bearing zooplankton, are becoming an important sentinel organism for understanding the influence of ocean acidification on pelagic organisms. These animals show vulnerability to changing carbonate chemistry conditions, are geographically widespread, and are both biogeochemically and trophically important. The objective of this study was to determine how increasing duration and severity of CO2 treatment influence the physiology of the thecosome Limacina retroversa, integrating both gene expression and organism-level (respiration and calcification) metrics. We exposed pteropods to over-saturated, near-saturated or under-saturated conditions and sampled individuals at 1, 3, 7, 14 and 21 days of exposure to test for the effect of duration. We found that calcification was affected by borderline and under saturated conditions by week two, while respiration appeared to be more strongly influenced by an interaction between severity and duration of exposure, showing complex changes by one week of exposure. The organismal metrics were corroborated by specific gene expression responses, with increased expression of biomineralization-associated genes in the medium and high treatments throughout and complex changes in metabolic genes corresponding to both captivity and CO2 treatment. Genes associated with other physiological processes such as lipid metabolism, neural function and ion pumping had complex responses, influenced by both duration and severity. Beyond these responses, our findings detail the captivity effects for these pelagic organisms, providing information to contextualize the conclusions of previous studies, and emphasizing a need for better culturing protocols. PMID- 29191862 TI - GABAA receptors activate fish feeding behaviour via two distinct functional pathways. AB - Benzodiazepines, acting through ionotropic receptors of gamma-aminobutyric acid (GABAA receptors, GABAR), have been shown to modify feeding behaviour and increase appetite in humans and non-human subjects. However, the cellular and molecular mechanisms that underlie connected short-term behavioural fluctuations are still unclear. In the present study, we used Carassius gibelio (Prussian carp) as a model organism to research the impact of scantily explored benzodiazepine phenazepam (PNZ) on feeding behaviour and the related molecular mechanisms of PNZ action at single-cell and single-receptor levels. We found that the feeding activity of C. gibelio is under control of GABARs via two distinct mechanisms: orthosteric (triggered by GABA binding site) and allosteric (triggered by benzodiazepine binding site). PNZ displayed clear stimulatory effects on both mechanisms in a GABA-dependent manner. In addition, orthosteric and allosteric effects were found to be partially competitive, which leads to complex behavioural repercussions of conjoint effects of GABAR ligands. PMID- 29191864 TI - Ontogeny and morphometrics of the gills and swim bladder of air-breathing striped catfish Pangasianodon hypophthalmus. AB - The air-breathing fish Pangasianodon hypophthalmus has been shown to have highly plastic branchial surfaces whose area (SA) increases with temperature and aquatic hypoxia. This modulation occurs through development of inter-lamellar cell mass (ILCM). Paradoxically, in conditions where this fish has been shown capable of covering its entire aerobic scope from the water phase, it has been shown to have a very small branchial SA. To address this paradox, we measured the SA, harmonic mean diffusion distance (tauh) and calculated the anatomic diffusion factor (ADF) of the branchial and swim bladder surfaces in fish ranging from 3 to 1900 g at 27 degrees C in normoxia. Since the lamellae were distinguishable from the ILCM, we measured the actual SA as well as the potential SA if ILCM were lost. As a result of low tauh, P. hypophthalmus has a high capacity for branchial oxygen uptake with or without ILCM. Actual and potential gill ADF were 361 and 1002 cm2 um-1 kg 1, respectively, for a 100 g fish and the ADF of the swim bladder was found to be 308 cm2 um-1 kg-1 By swimming fish to exhaustion at different temperatures, we show that modulation of this SA is rapid, indicating that the apparent paradox between previous studies is eliminated. Regression analysis of log-log plots of respiratory SA in relation to body mass shows that the gill scales with mass similarly to the SA in active water-breathing fish, whereas the swim bladder scales with mass more like the mammalian lung does. This fish presents a combination of respiratory surfaces not previously seen in air-breathing fish.

AB - Global sagittal malalignment has been demonstrated to have correlation with clinical symptoms and is a key component to be restored in adult spinal deformity. In this article, various types of sagittal balance-correction osteotomies are reviewed primarily on the basis of the 3 most commonly used procedures: Smith-Petersen osteotomy, pedicle subtraction osteotomy, and vertebral column resection. Familiarity with the expected imaging appearance and commonly encountered complications seen on postoperative imaging studies following correction osteotomies is crucial for accurate image interpretation. PMID- 29191869 TI - John Nash and the Organization of Stroke Care. AB - The concept of Nash equilibrium, developed by John Forbes Nash Jr, states that an equilibrium in noncooperative games is reached when each player takes the best action for himself or herself, taking into account the actions of the other players. We apply this concept to the provision of endovascular thrombectomy in the treatment of acute ischemic stroke and suggest that collaboration among hospitals in a health care jurisdiction could result in practices such as shared call pools for neurointervention teams, leading to better patient care through streamlined systems. PMID- 29191870 TI - Reproducibility of Deep Gray Matter Atrophy Rate Measurement in a Large Multicenter Dataset. AB - BACKGROUND AND PURPOSE: Precise in vivo measurement of deep GM volume change is a highly demanded prerequisite for an adequate evaluation of disease progression and new treatments. However, quantitative data on the reproducibility of deep GM structure volumetry are not yet available. In this paper we aim to investigate this reproducibility using a large multicenter dataset. MATERIALS AND METHODS: We have assessed the reproducibility of 2 automated segmentation software packages (FreeSurfer and the FMRIB Integrated Registration and Segmentation Tool) by quantifying the volume changes of deep GM structures by using back-to-back MR imaging scans from the Alzheimer Disease Neuroimaging Initiative's multicenter dataset. Five hundred sixty-two subjects with scans at baseline and 1 year were included. Reproducibility was investigated in the bilateral caudate nucleus, putamen, amygdala, globus pallidus, and thalamus by carrying out descriptives as well as multilevel and variance component analysis. RESULTS: Median absolute back to-back differences varied between GM structures, ranging from 59.6-156.4 MUL for volume change, and 1.26%-8.63% for percentage volume change. FreeSurfer had a better performance for the outcome of longitudinal volume change for the bilateral amygdala, putamen, left caudate nucleus (P < .005), and right thalamus (P < .001). For longitudinal percentage volume change, Freesurfer performed better for the left amygdala, bilateral caudate nucleus, and left putamen (P < .001). Smaller limits of agreement were found for FreeSurfer for both outcomes for all GM structures except the globus pallidus. Our results showed that back-to back differences in 1-year percentage volume change were approximately 1.5-3.5 times larger than the mean measured 1-year volume change of those structures. CONCLUSIONS: Longitudinal deep GM atrophy measures should be interpreted with caution. Furthermore, deep GM atrophy measurement techniques require substantially improved reproducibility, specifically when aiming for personalized medicine. PMID- 29191871 TI - MR Imaging Characteristics Associate with Tumor-Associated Macrophages in Glioblastoma and Provide an Improved Signature for Survival Prognostication. AB - BACKGROUND AND PURPOSE: In glioblastoma, tumor-associated macrophages have tumor promoting properties. This study determined whether routine MR imaging features could predict molecular subtypes of glioblastoma that differ in the content of tumor-associated macrophages. MATERIALS AND METHODS: Seven internally derived MR imaging features were assessed in 180 patients, and 25 features from the Visually AcceSAble Rembrandt Images feature set were assessed in 164 patients. Glioblastomas were divided into subtypes based on the telomere maintenance mechanism: alternative lengthening of telomeres positive (ALT+) and negative (ALT ) and the content of tumor-associated macrophages (with [M+] or without [M-] a high content of macrophages). The 3 most frequent subtypes (ALT+/M-, ALT-/M+, and ALT-/M-) were correlated with MR imaging features and clinical parameters. The fourth group (ALT+/M+) did not have enough cases for correlation with MR imaging features. RESULTS: Tumors with a regular margin and those lacking a fungating margin, an expansive T1/FLAIR ratio, and reduced ependymal extension were more frequent in the subgroup of ALT+/M- (P < .05). Radiologic necrosis, lack of cystic component (by both criteria), and extensive peritumoral edema were more frequent in ALT-/M+ tumors (P < .05). Multivariate testing with a Cox regression analysis found the cystic imaging feature was additive to tumor subtype, and O6 methylguanine methyltransferase (MGMT) status to predict improved patient survival (P < .05). CONCLUSIONS: Glioblastomas with tumor-associated macrophages are associated with routine MR imaging features consistent with these tumors being more aggressive. Inclusion of cystic change with molecular subtypes and MGMT status provided a better estimate of survival. PMID- 29191872 TI - Influences for Gender Disparity in Academic Neuroradiology. AB - BACKGROUND AND PURPOSE: There has been extensive interest in promoting gender equality within radiology, a predominately male field. In this study, our aim was to quantify gender representation in neuroradiology faculty rankings and determine any related factors that may contribute to any such disparity. MATERIALS AND METHODS: We evaluated the academic and administrative faculty members of neuroradiology divisions for all on-line listed programs in the US and Canada. After excluding programs that did not fulfill our selection criteria, we generated a short list of 85 US and 8 Canadian programs. We found 465 faculty members who met the inclusion criteria for our study. We used Elsevier's SCOPUS for gathering the data pertaining to the publications, H-index, citations, and tenure of the productivity of each faculty member. RESULTS: Gender disparity was insignificant when analyzing academic ranks. There are more men working in neuroimaging relative to women (chi2 = 0.46; P = .79). However, gender disparity was highly significant for leadership positions in neuroradiology (chi2 = 6.76; P = .009). The median H-index was higher among male faculty members (17.5) versus female faculty members (9). Female faculty members have odds of 0.84 compared with male faculty members of having a higher H-index, adjusting for publications, citations, academic ranks, leadership ranks, and interaction between gender and publications and gender and citations (9). CONCLUSIONS: Neuroradiology faculty members follow the same male predominance seen in many other specialties of medicine. In this study, issues such as mentoring, role models, opportunities to engage in leadership/research activities, funding opportunities, and mindfulness regarding research productivity are explored. PMID- 29191873 TI - Time for a Time Window Extension: Insights from Late Presenters in the ESCAPE Trial. AB - BACKGROUND AND PURPOSE: The safety and efficacy of endovascular therapy for large artery stroke in the extended time window is not yet well-established. We performed a subgroup analysis on subjects enrolled within an extended time window in the Endovascular Treatment for Small Core and Proximal Occlusion Ischemic Stroke (ESCAPE) trial. MATERIALS AND METHODS: Fifty-nine of 315 subjects (33 in the intervention group and 26 in the control group) were randomized in the ESCAPE trial between 5.5 and 12 hours after last seen healthy (likely to have groin puncture administered 6 hours after that). Treatment effect sizes for all relevant outcomes (90-day mRS shift, mRS 0-2, mRS 0-1, and 24-hour NIHSS scores and intracerebral hemorrhage) were reported using unadjusted and adjusted analyses. RESULTS: There was no evidence of treatment heterogeneity between subjects in the early and late windows. Treatment effect favoring intervention was seen across all clinical outcomes in the extended time window (absolute risk difference of 19.3% for mRS 0-2 at 90 days). There were more asymptomatic intracerebral hemorrhage events within the intervention arm (48.5% versus 11.5%, P = .004) but no difference in symptomatic intracerebral hemorrhage. CONCLUSIONS: Patients with an extended time window could potentially benefit from endovascular treatment. Ongoing randomized controlled trials using imaging to identify late presenters with favorable brain physiology will help cement the paradigm of using time windows to select the population for acute imaging and imaging to select individual patients for therapy. PMID- 29191874 TI - CT Attenuation Analysis of Carotid Intraplaque Hemorrhage. AB - BACKGROUND AND PURPOSE: Intraplaque hemorrhage is considered a leading parameter of carotid plaque vulnerability. Our purpose was to assess the CT characteristics of intraplaque hemorrhage with histopathologic correlation to identify features that allow for confirming or ruling out the intraplaque hemorrhage. MATERIALS AND METHODS: This retrospective study included 91 patients (67 men; median age, 65 +/ 7 years; age range, 41-83 years) who underwent CT angiography and carotid endarterectomy from March 2010 to May 2013. Histopathologic analysis was performed for the tissue characterization and identification of intraplaque hemorrhage. Two observers assessed the plaque's attenuation values by using an ROI (>= 1 and <=2 mm2). Receiver operating characteristic curve, Mann-Whitney, and Wilcoxon analyses were performed. RESULTS: A total of 169 slices were assessed (59 intraplaque hemorrhage, 63 lipid-rich necrotic core, and 47 fibrous); the average values of the intraplaque hemorrhage, lipid-rich necrotic core, and fibrous tissue were 17.475 Hounsfield units (HU) and 18.407 HU, 39.476 HU and 48.048 HU, and 91.66 HU and 93.128 HU, respectively, before and after the administration of contrast medium. The Mann-Whitney test showed a statistically significant difference of HU values both in basal and after the administration of contrast material phase. Receiver operating characteristic analysis showed a statistical association between intraplaque hemorrhage and low HU values, and a threshold of 25 HU demonstrated the presence of intraplaque hemorrhage with a sensitivity and specificity of 93.22% and 92.73%, respectively. The Wilcoxon test showed that the attenuation of the plaque before and after administration of contrast material is different (intraplaque hemorrhage, lipid-rich necrotic core, and fibrous tissue had P values of .006, .0001, and .018, respectively). CONCLUSIONS: The results of this preliminary study suggest that CT can be used to identify the presence of intraplaque hemorrhage according to the attenuation. A threshold of 25 HU in the volume acquired after the administration of contrast medium is associated with an optimal sensitivity and specificity. Special care should be given to the correct identification of the ROI. PMID- 29191875 TI - Lymphographic-Like Technique for the Treatment of Microcystic Lymphatic Malformation Components of <3 mm. AB - BACKGROUND AND PURPOSE: The treatment of microcystic lymphatic malformations remains challenging. Our aim was to describe the lymphographic-like technique, a new technique of slow bleomycin infusion for the treatment of microcyst components of <3 mm, performed at our institution. MATERIALS AND METHODS: A retrospective analysis of a prospectively collected lymphatic malformation data base was performed. Patients with at least 1 microcystic lymphatic malformation component demonstrated on MR imaging treated by lymphographic-like technique bleomycin infusion were included in the study. Patient interviews and MR imaging were performed to assess subjective and objective (microcystic lymphatic malformation size decrease of >30%) clinical improvement, respectively. Patients were reviewed 3 months after each sclerotherapy session. Lymphographic-like technique safety and efficacy were assessed. RESULTS: Between January 2012 and July 2016, sixteen patients (5 males, 11 females; mean age, 15 years; range, 1-47 years) underwent the bleomycin lymphographic-like technique for microcystic lymphatic malformations. Sixty sclerotherapy sessions were performed, with a mean of 4 sessions per patient (range, 1-8 sessions) and a mean follow-up of 26 months (range, 5-58 months). We observed no major and 3 minor complications: 1 eyelid infection, 1 case of severe postprocedural nausea and vomiting, and 1 case of skin discoloration. One patient was lost to follow-up. Overall MR imaging objective improvement was observed in 5/16 (31%) patients; overall improvement of clinical symptoms was obtained in 93% of treated patients. CONCLUSIONS: The bleomycin lymphographic-like technique for microcystic lymphatic malformations is safe and feasible with objective improvement in about one-third of patients. MR signal intensity changes after the lymphographic-like technique are associated with subjective improvement of the patient's symptoms. PMID- 29191876 TI - Comment on "Water harvesting from air with metal-organic frameworks powered by natural sunlight". AB - Kim et al (Reports, 28 April 2017, p. 430) presented results for the solar-driven harvesting of water from air via metal-organic frameworks as a prodigious potential advance toward remedying global water shortages. Basic thermodynamics and a survey of multiple off-the-shelf technologies show that their approach is vastly inferior in efficiency (and thereby in feasibility) to available alternatives. PMID- 29191877 TI - Response to Comment on "Water harvesting from air with metal-organic frameworks powered by natural sunlight". AB - In their comment, Bui et al argue that the approach we described in our report is vastly inferior in efficiency to alternative off-the-shelf technologies. Their conclusion is invalid, as they compare efficiencies in completely different operating conditions. Here, using heat transfer and thermodynamics principles, we show how Bui et al's conclusions about the efficiencies of off-the-shelf technologies are fundamentally flawed and inaccurate for the operating conditions described in our study.

PMID- 29191878 TI - The target landscape of clinical kinase drugs. AB - Kinase inhibitors are important cancer therapeutics. Polypharmacology is commonly observed, requiring thorough target deconvolution to understand drug mechanism of action. Using chemical proteomics, we analyzed the target spectrum of 243 clinically evaluated kinase drugs. The data revealed previously unknown targets for established drugs, offered a perspective on the "druggable" kinome, highlighted (non)kinase off-targets, and suggested potential therapeutic applications. Integration of phosphoproteomic data refined drug-affected pathways, identified response markers, and strengthened rationale for combination treatments. We exemplify translational value by discovering SIK2 (salt-inducible kinase 2) inhibitors that modulate cytokine production in primary cells, by identifying drugs against the lung cancer survival marker MELK (maternal embryonic leucine zipper kinase), and by repurposing cabozantinib to treat FLT3 ITD-positive acute myeloid leukemia. This resource, available via the ProteomicsDB database, should facilitate basic, clinical, and drug discovery research and aid clinical decision-making.

PMID- 29191879 TI - Osteoblasts remotely supply lung tumors with cancer-promoting SiglecFhigh neutrophils. AB - Bone marrow-derived myeloid cells can accumulate within tumors and foster cancer outgrowth. Local immune-neoplastic interactions have been intensively investigated, but the contribution of the systemic host environment to tumor growth remains poorly understood. Here, we show in mice and cancer patients (n = 70) that lung adenocarcinomas increase bone stromal activity in the absence of bone metastasis. Animal studies reveal that the cancer-induced bone phenotype involves bone-resident osteocalcin-expressing (Ocn+) osteoblastic cells. These cells promote cancer by remotely supplying a distinct subset of tumor infiltrating SiglecFhigh neutrophils, which exhibit cancer-promoting properties. Experimentally reducing Ocn+ cell numbers suppresses the neutrophil response and lung tumor outgrowth. These observations posit osteoblasts as remote regulators of lung cancer and identify SiglecFhigh neutrophils as myeloid cell effectors of the osteoblast-driven protumoral response.

AB - Marine ecosystem models have advanced to incorporate metabolic pathways discovered with genomic sequencing, but direct comparisons between models and "omics" data are lacking. We developed a model that directly simulates metagenomes and metatranscriptomes for comparison with observations. Model microbes were randomly assigned genes for specialized functions, and communities of 68 species were simulated in the Atlantic Ocean. Unfit organisms were replaced, and the model self-organized to develop community genomes and transcriptomes. Emergent communities from simulations that were initialized with different cohorts of randomly generated microbes all produced realistic vertical and horizontal ocean nutrient, genome, and transcriptome gradients. Thus, the library of gene functions available to the community, rather than the distribution of functions among specific organisms, drove community assembly and biogeochemical gradients in the model ocean. PMID- 29191901 TI - Stripe order in the underdoped region of the two-dimensional Hubbard model. AB - Competing inhomogeneous orders are a central feature of correlated electron materials, including the high-temperature superconductors. The two-dimensional Hubbard model serves as the canonical microscopic physical model for such systems. Multiple orders have been proposed in the underdoped part of the phase diagram, which corresponds to a regime of maximum numerical difficulty. By combining the latest numerical methods in exhaustive simulations, we uncover the ordering in the underdoped ground state. We find a stripe order that has a highly compressible wavelength on an energy scale of a few kelvin, with wavelength fluctuations coupled to pairing order. The favored filled stripe order is different from that seen in real materials. Our results demonstrate the power of modern numerical methods to solve microscopic models, even in challenging settings. PMID- 29191902 TI - Numerical evidence of fluctuating stripes in the normal state of high-Tc cuprate superconductors. AB - Upon doping, Mott insulators often exhibit symmetry breaking where charge carriers and their spins organize into patterns known as stripes. For high transition temperature cuprate superconductors, stripes are widely suspected to exist in a fluctuating form. We used numerically exact determinant quantum Monte Carlo calculations to demonstrate dynamical stripe correlations in the three-band Hubbard model, which represents the local electronic structure of the copper oxygen plane. Our results, which are robust to varying parameters, cluster size, and boundary conditions, support the interpretation of experimental observations such as the hourglass magnetic dispersion and the Yamada plot of incommensurability versus doping in terms of the physics of fluctuating stripes. These findings provide a different perspective on the intertwined orders emerging from the cuprates' normal state. PMID- 29191903 TI - Observations and modeling of the elastogravity signals preceding direct seismic waves. AB - After an earthquake, the earliest deformation signals are not expected to be carried by the fastest (P) elastic waves but by the speed-of-light changes of the gravitational field. However, these perturbations are weak and, so far, their detection has not been accurate enough to fully understand their origins and to use them for a highly valuable rapid estimate of the earthquake magnitude. We show that gravity perturbations are particularly well observed with broadband seismometers at distances between 1000 and 2000 kilometers from the source of the 2011, moment magnitude 9.1, Tohoku earthquake. We can accurately model them by a new formalism, taking into account both the gravity changes and the gravity induced motion. These prompt elastogravity signals open the window for minute time-scale magnitude determination for great earthquakes. PMID- 29191904 TI - Organocalcium-mediated nucleophilic alkylation of benzene. AB - The electrophilic aromatic substitution of a C-H bond of benzene is one of the archetypal transformations of organic chemistry. In contrast, the electron-rich pi-system of benzene is highly resistant to reactions with electron-rich and negatively charged organic nucleophiles. Here, we report that this previously insurmountable electronic repulsion may be overcome through the use of sufficiently potent organocalcium nucleophiles. Calcium n-alkyl derivatives synthesized by reaction of ethene, but-1-ene, and hex-1-ene with a dimeric calcium hydride-react with protio and deutero benzene at 60 degrees C through nucleophilic substitution of an aromatic C-D/H bond. These reactions produce the n-alkyl benzenes with regeneration of the calcium hydride. Density functional theory calculations implicate an unstabilized Meisenheimer complex in the C-H activation transition state. PMID- 29191905 TI - The image-forming mirror in the eye of the scallop. AB - Scallops possess a visual system comprising up to 200 eyes, each containing a concave mirror rather than a lens to focus light. The hierarchical organization of the multilayered mirror is controlled for image formation, from the component guanine crystals at the nanoscale to the complex three-dimensional morphology at the millimeter level. The layered structure of the mirror is tuned to reflect the wavelengths of light penetrating the scallop's habitat and is tiled with a mosaic of square guanine crystals, which reduces optical aberrations. The mirror forms images on a double-layered retina used for separately imaging the peripheral and central fields of view. The tiled, off-axis mirror of the scallop eye bears a striking resemblance to the segmented mirrors of reflecting telescopes. PMID- 29191906 TI - Spectroscopic signatures of localization with interacting photons in superconducting qubits. AB - Quantized eigenenergies and their associated wave functions provide extensive information for predicting the physics of quantum many-body systems. Using a chain of nine superconducting qubits, we implement a technique for resolving the energy levels of interacting photons. We benchmark this method by capturing the main features of the intricate energy spectrum predicted for two-dimensional electrons in a magnetic field-the Hofstadter butterfly. We introduce disorder to study the statistics of the energy levels of the system as it undergoes the transition from a thermalized to a localized phase. Our work introduces a many body spectroscopy technique to study quantum phases of matter. PMID- 29191907 TI - Giant nonlinear response at a plasmonic nanofocus drives efficient four-wave mixing. AB - Efficient optical frequency mixing typically must accumulate over large interaction lengths because nonlinear responses in natural materials are inherently weak. This limits the efficiency of mixing processes owing to the requirement of phase matching. Here, we report efficient four-wave mixing (FWM) over micrometer-scale interaction lengths at telecommunications wavelengths on silicon. We used an integrated plasmonic gap waveguide that strongly confines light within a nonlinear organic polymer. The gap waveguide intensifies light by nanofocusing it to a mode cross-section of a few tens of nanometers, thus generating a nonlinear response so strong that efficient FWM accumulates over wavelength-scale distances. This technique opens up nonlinear optics to a regime of relaxed phase matching, with the possibility of compact, broadband, and efficient frequency mixing integrated with silicon photonics. PMID- 29191908 TI - Selective increase in CO2 electroreduction activity at grain-boundary surface terminations. AB - Altering a material's catalytic properties requires identifying structural features that give rise to active surfaces. Grain boundaries create strained regions in polycrystalline materials by stabilizing dislocations and may provide a way to create high-energy surfaces for catalysis that are kinetically trapped. Although grain-boundary density has previously been correlated with catalytic activity for some reactions, direct evidence that grain boundaries create surfaces with enhanced activity is lacking. We used a combination of bulk electrochemical measurements and scanning electrochemical cell microscopy with submicrometer resolution to show that grain-boundary surface terminations in gold electrodes are more active than grain surfaces for electrochemical carbon dioxide (CO2) reduction to carbon monoxide (CO) but not for the competing hydrogen (H2) evolution reaction. The catalytic footprint of the grain boundary is commensurate with its dislocation-induced strain field, providing a strategy for broader exploitation of grain-boundary effects in heterogeneous catalysis. PMID- 29191909 TI - Egg accumulation with 3D embryos provides insight into the life history of a pterosaur. AB - Fossil eggs and embryos that provide unique information about the reproduction and early growth of vertebrates are exceedingly rare, particularly for pterosaurs. Here we report on hundreds of three-dimensional (3D) eggs of the species Hamipterus tianshanensis from a Lower Cretaceous site in China, 16 of which contain embryonic remains. Computed tomography scanning, osteohistology, and micropreparation reveal that some bones lack extensive ossification in potentially late-term embryos, suggesting that hatchlings might have been flightless and less precocious than previously assumed. The geological context, including at least four levels with embryos and eggs, indicates that this deposit was formed by a rare combination of events, with storms acting on a nesting ground. This discovery supports colonial nesting behavior and potential nesting site fidelity in the Pterosauria. PMID- 29191910 TI - Host DNases prevent vascular occlusion by neutrophil extracellular traps. AB - Platelet and fibrin clots occlude blood vessels in hemostasis and thrombosis. Here we report a noncanonical mechanism for vascular occlusion based on neutrophil extracellular traps (NETs), DNA fibers released by neutrophils during inflammation. We investigated which host factors control NETs in vivo and found that two deoxyribonucleases (DNases), DNase1 and DNase1-like 3, degraded NETs in circulation during sterile neutrophilia and septicemia. In the absence of both DNases, intravascular NETs formed clots that obstructed blood vessels and caused organ damage. Vascular occlusions in patients with severe bacterial infections were associated with a defect to degrade NETs ex vivo and the formation of intravascular NET clots. DNase1 and DNase1-like 3 are independently expressed and thus provide dual host protection against deleterious effects of intravascular NETs. PMID- 29191912 TI - Being out in STEM. PMID- 29191911 TI - 3.9 A structure of the yeast Mec1-Ddc2 complex, a homolog of human ATR-ATRIP. AB - The ataxia telangiectasia-mutated and Rad3-related (ATR) kinase is a master regulator of DNA damage response and replication stress in humans, but the mechanism of its activation remains unclear. ATR acts together with its partner ATRIP. Using cryo-electron microscopy, we determined the structure of intact Mec1 Ddc2 (the yeast homolog of ATR-ATRIP), which is poised for catalysis, at a resolution of 3.9 angstroms. Mec1-Ddc2 forms a dimer of heterodimers through the PRD and FAT domains of Mec1 and the coiled-coil domain of Ddc2. The PRD and Bridge domains in Mec1 constitute critical regulatory sites. The activation loop of Mec1 is inhibited by the PRD, revealing an allosteric mechanism of kinase activation. Our study clarifies the architecture of ATR-ATRIP and provides a structural framework for the understanding of ATR regulation. PMID- 29191913 TI - Metabolic reprogramming of human CD8+ memory T cells through loss of SIRT1. AB - The expansion of CD8+CD28- T cells, a population of terminally differentiated memory T cells, is one of the most consistent immunological changes in humans during aging. CD8+CD28- T cells are highly cytotoxic, and their frequency is linked to many age-related diseases. As they do not accumulate in mice, many of the molecular mechanisms regulating their fate and function remain unclear. In this paper, we find that human CD8+CD28- T cells, under resting conditions, have an enhanced capacity to use glycolysis, a function linked to decreased expression of the NAD+-dependent protein deacetylase SIRT1. Global gene expression profiling identified the transcription factor FoxO1 as a SIRT1 target involved in transcriptional reprogramming of CD8+CD28- T cells. FoxO1 is proteasomally degraded in SIRT1-deficient CD8+CD28- T cells, and inhibiting its activity in resting CD8+CD28+ T cells enhanced glycolytic capacity and granzyme B production as in CD8+CD28- T cells. These data identify the evolutionarily conserved SIRT1 FoxO1 axis as a regulator of resting CD8+ memory T cell metabolism and activity in humans. PMID- 29191915 TI - Platelets and vascular integrity: how platelets prevent bleeding in inflammation. AB - Platelets play a central role in primary hemostasis by forming aggregates that plug holes in injured vessels. Half a century ago, detailed studies of the microvasculature by electron microscopy revealed that under inflammatory conditions that do not induce major disruption to vascular structure, individual platelets are mobilized to the vessel wall, where they interact with leukocytes and appear to seal gaps that arise between endothelial cells. Recent developments in genetic engineering and intravital microscopy have allowed further molecular and temporal characterization of these events. Surprisingly, it turns out that platelets support the recruitment of leukocytes to sites of inflammation. In parallel, however, they exercise their hemostatic function by securing the integrity of inflamed blood vessels to prevent bleeding from sites of leukocyte infiltration. It thus appears that platelets not only serve in concert as building blocks of the hemostatic plug but also act individually as gatekeepers of the vascular wall to help preserve vascular integrity while coordinating host defense. Variants of this recently appreciated hemostatic function of platelets that we refer to as "inflammation-associated hemostasis" are engaged in different contexts in which the endothelium is challenged or dysfunctional. Although the distinguishing characteristics of these variants and the underlying mechanisms of inflammation-associated hemostasis remain to be fully elucidated, they can differ notably from those supporting thrombosis, thus presenting therapeutic opportunities. PMID- 29191916 TI - Duvelisib, a novel oral dual inhibitor of PI3K-delta,gamma, is clinically active in advanced hematologic malignancies. AB - Duvelisib is an oral dual inhibitor of phosphoinositide 3-kinase-delta (PI3K delta) and PI3K-gamma in late-stage clinical development for hematologic malignancy treatment. This phase 1 study evaluated maximum tolerated dose (MTD), pharmacokinetics, pharmacodynamics (PD), efficacy, and safety of duvelisib in 210 patients with advanced hematologic malignancies. In the dose escalation phase (n = 31), duvelisib 8 to 100 mg twice daily was administered, with MTD determined as 75 mg twice daily. In the expansion phase (n = 179), patients with indolent non Hodgkin lymphoma (iNHL), chronic lymphocytic leukemia (CLL), or T-cell lymphoma (TCL) were treated with 25 or 75 mg duvelisib twice daily continuously. Single dose duvelisib was rapidly absorbed (time to maximum concentration, 1-2 hours), with a half-life of 5.2 to 10.9 hours. PD results showed inhibition of phospho AKT (S473) in CLL tumor cells following a single dose and near-complete inhibition of CLL proliferation (Ki-67) by cycle 2. Clinical responses were seen across a range of doses and disease subtypes: iNHL overall response rate, 58% (n = 31) with 6 complete responses (CRs); relapsed/refractory CLL, 56% (n = 55) with 1 CR; peripheral TCL, 50% (n = 16) with 3 CR; and cutaneous TCL, 32% (n = 19). Median time to response was ~1.8 months. Severe (grade >=3) adverse events occurred in 84% of patients: neutropenia (32%), alanine transaminase increase (20%), aspartate transaminase increase (15%), anemia and thrombocytopenia (each 14%), diarrhea (11%), and pneumonia (10%). These data support further investigation of duvelisib in phase 2 and 3 studies. This trial was registered at clinicaltrials.gov as #NCT01476657.

PMID- 29191914 TI - Resolvins suppress tumor growth and enhance cancer therapy. AB - Cancer therapy reduces tumor burden by killing tumor cells, yet it simultaneously creates tumor cell debris that may stimulate inflammation and tumor growth. Thus, conventional cancer therapy is inherently a double-edged sword. In this study, we show that tumor cells killed by chemotherapy or targeted therapy ("tumor cell debris") stimulate primary tumor growth when coinjected with a subthreshold (nontumorigenic) inoculum of tumor cells by triggering macrophage proinflammatory cytokine release after phosphatidylserine exposure. Debris-stimulated tumors were inhibited by antiinflammatory and proresolving lipid autacoids, namely resolvin D1 (RvD1), RvD2, or RvE1. These mediators specifically inhibit debris-stimulated cancer progression by enhancing clearance of debris via macrophage phagocytosis in multiple tumor types. Resolvins counterregulate the release of cytokines/chemokines, including TNFalpha, IL-6, IL-8, CCL4, and CCL5, by human macrophages stimulated with cell debris. These results demonstrate that enhancing endogenous clearance of tumor cell debris is a new therapeutic target that may complement cytotoxic cancer therapies. PMID- 29191918 TI - Pml nuclear body disruption cooperates in APL pathogenesis and impairs DNA damage repair pathways in mice. AB - A hallmark of acute promyelocytic leukemia (APL) is altered nuclear architecture, with disruption of promyelocytic leukemia (PML) nuclear bodies (NBs) mediated by the PML-retinoic acid receptor alpha (RARalpha) oncoprotein. To address whether this phenomenon plays a role in disease pathogenesis, we generated a knock-in mouse model with NB disruption mediated by 2 point mutations (C62A/C65A) in the Pml RING domain. Although no leukemias developed in PmlC62A/C65A mice, these transgenic mice also expressing RARalpha linked to a dimerization domain (p50 RARalpha model) exhibited a doubling in the rate of leukemia, with a reduced latency period. Additionally, we found that response to targeted therapy with all trans retinoic acid in vivo was dependent on NB integrity. PML-RARalpha is recognized to be insufficient for development of APL, requiring acquisition of cooperating mutations. We therefore investigated whether NB disruption might be mutagenic. Compared with wild-type cells, primary PmlC62A/C65A cells exhibited increased sister-chromatid exchange and chromosome abnormalities. Moreover, functional assays showed impaired homologous recombination (HR) and nonhomologous end-joining (NHEJ) repair pathways, with defective localization of Brca1 and Rad51 to sites of DNA damage. These data directly demonstrate that Pml NBs are critical for DNA damage responses, and suggest that Pml NB disruption is a central contributor to APL pathogenesis. PMID- 29191919 TI - On type 1 diabetes mellitus pathogenesis. AB - Type 1 diabetes mellitus (T1DM) results from the autoimmune destruction of beta cells of the endocrine pancreas. Pathogenesis of T1DM is different from that of type 2 diabetes mellitus, where both insulin resistance and reduced secretion of insulin by the beta cells play a synergistic role. We will present genetic, environmental and immunologic factors that destroy beta cells of the endocrine pancreas and lead to insulin deficiency. The process of autoimmune destruction takes place in genetically susceptible individuals under the triggering effect of one or more environmental factors and usually progresses over a period of many months to years, during which period patients are asymptomatic and euglycemic, but positive for relevant autoantibodies. Symptomatic hyperglycemia and frank diabetes occur after a long latency period, which reflects the large percentage of beta cells that need to be destroyed before overt diabetes become evident. PMID- 29191920 TI - Combined test of serum CgA and NSE improved the power of prognosis prediction of NF-pNETs. AB - PURPOSE: Chromogranin A (CgA) and neuron-specific enolase (NSE) are important markers for neuroendocrine tumors; however, the clinical value of combining these markers has not been well studied. In this study, we investigated the utility of each marker individually and in combination for patients with nonfunctional pancreatic neuroendocrine tumors (NF-pNETs). PATIENTS AND METHODS: In this study, NF-pNET patients and controls were recruited from December 2011 to March 2016; 784 serum samples from peripheral vein were collected. The clinical characteristics and biomarker values of all the individuals were recorded and analyzed. Tumor burdens were calculated by CT/MRI scan. Receiver-operating characteristic curves were constructed to assess the diagnostic predictive values; sensitivity and specificity were calculated to determine the cut-off value. Therapeutic responses reflected on the changes of the biomarkers' concentration were assessed by the RECIST criterion. Clinical relations between the prognosis and the biomarker values were also analyzed. Statistical significance was defined as P value less than 0.05. RESULTS: Among the 167 NF pNETs patients, 82 were males (49.1%) and the mean age was 50.0 (17.4). The mean CgA values of G1, G2 and G3 NF-pNENs were 75, 121 and 134 MUg/L (P < 0.05), respectively. In NF-pNETs, CgA correlated with the WHO tumor grade (WHO G1 vs G2, P < 0.05); the linear regression relationships were found between the tumor burdens (both in pancreas and liver) and CgA concentration (P < 0.001); changes in CgA and NSE concentrations also reflect treatment response (P < 0.001). CONCLUSION: CgA and NSE are important diagnostic and follow-up markers in patients with NF-pNETs. The combined monitoring of CgA and NSE possesses more accuracy than individual values of CgA and NSE at predicting prognosis and disease progression. PMID- 29191921 TI - Selective EGFR (Epidermal Growth Factor Receptor) Deletion in Myeloid Cells Limits Atherosclerosis-Brief Report. AB - OBJECTIVE: To determine the consequences of specific inhibition of EGFR (epidermal growth factor receptor) in myeloid cells in atherosclerosis development. APPROACH AND RESULTS: Atherosclerotic lesion size was significantly reduced in irradiated Ldlr-/- mice reconstituted with LysMCre+Egfrlox/lox bone marrow, compared with chimeric Ldlr-/- mice reconstituted with LysMCre Egfrlox/lox bone marrow, after 4 (-43%; P<0.05), 7 (-34%; P<0.05), and 12 weeks ( 54%; P<0.001) of high-fat diet. Reduction of lesion size was associated with marked reduction in macrophage accumulation and necrotic core size. Specific deletion of Egfr in myeloid cells reduced TNF-alpha (tumor necrosis factor-alpha) and IL (interleukin)-6 production by stimulated macrophages but had no effect on IL-10 and IL-12p70 secretion. Finally, we found that myeloid deletion of Egfr limited cytoskeletal rearrangements and also lipid uptake by macrophages through a downregulation of the scavenger receptor CD36 (cluster of differentiation 36). CONCLUSIONS: Gene deletion of Egfr in myeloid cells limits IL-6 and TNF-alpha production, lipid uptake, and consecutively reduces atherosclerosis development. PMID- 29191922 TI - Adventitial Sca1+ Cells Transduced With ETV2 Are Committed to the Endothelial Fate and Improve Vascular Remodeling After Injury. AB - OBJECTIVE: Vascular adventitial Sca1+ (stem cell antigen-1) progenitor cells preferentially differentiate into smooth muscle cells, which contribute to vascular remodeling and neointima formation in vessel grafts. Therefore, directing the differentiation of Sca1+ cells toward the endothelial lineage could represent a new therapeutic strategy against vascular disease. APPROACH AND RESULTS: We thus developed a fast, reproducible protocol based on the single-gene transfer of ETV2 (ETS variant 2) to differentiate Sca1+ cells toward the endothelial fate and studied the effect of cell conversion on vascular hyperplasia in a model of endothelial injury. After ETV2 transduction, Sca1+ adventitial cells presented a significant increase in the expression of early endothelial cell genes, including VE-cadherin, Flk-1, and Tie2 at the mRNA and protein levels. ETV2 overexpression also induced the downregulation of a panel of smooth muscle cell and mesenchymal genes through epigenetic regulations, by decreasing the expression of DNA-modifying enzymes ten-eleven translocation dioxygenases. Adventitial Sca1+ cells grafted on the adventitial side of wire injured femoral arteries increased vascular wall hyperplasia compared with control arteries with no grafted cells. Arteries seeded with ETV2-transduced cells, on the contrary, showed reduced hyperplasia compared with control. CONCLUSIONS: These data give evidence that the genetic manipulation of vascular progenitors is a promising approach to improve vascular function after endothelial injury. PMID- 29191924 TI - Both Autocrine Signaling and Paracrine Signaling of HB-EGF Enhance Ocular Neovascularization. AB - OBJECTIVE: The incidence of blindness is increasing because of the increase in abnormal ocular neovascularization. Anti-VEGF (vascular endothelial growth factor) therapies have led to good results, although they are not a cure for the blindness. The purpose of this study was to determine what role HB-EGF (heparin binding epidermal growth factor-like growth factor) plays in ocular angiogenesis. APPROACH AND RESULTS: We examined the role played by HB-EGF in ocular neovascularization in 2 animal models of neovascularization: laser-induced choroidal neovascularization (CNV) and oxygen-induced retinopathy. We also studied human retinal microvascular endothelial cells in culture. Our results showed that the neovascularization was decreased in both the CNV and oxygen induced retinopathy models in HB-EGF conditional knockout mice compared with that in wild-type mice. Moreover, the expressions of HB-EGF and VEGF were increased after laser-induced CNV and oxygen-induced retinopathy, and their expression sites were located around the neovascular areas. Exposure of human retinal microvascular endothelial cells to HB-EGF and VEGF increased their proliferation and migration, and CRM-197 (cross-reactive material-197), an HB-EGF inhibitor, decreased the HB-EGF-induced and VEGF-induced cell proliferation and migration. VEGF increased the expression of HB-EGF mRNA. VEGF-dependent activation of EGFR (epidermal growth factor receptor)/ERK1/2 (extracellular signal-regulated kinase 1/2) signaling and cell proliferation of endothelial cells required stimulation of the ADAM17 (a disintegrin and metalloprotease) and ADAM12. CRM-197 decreased the grades of the fluorescein angiograms and size of the CNV areas in marmoset monkeys. CONCLUSIONS: These findings suggest that HB-EGF plays an important role in the development of CNV. Therefore, further investigations of HB-EGF are needed as a potential therapeutic target in the treatment of exudative age-related macular degeneration. PMID- 29191923 TI - Sortilin and Its Multiple Roles in Cardiovascular and Metabolic Diseases. AB - Cardiovascular disease is a leading cause of morbidity and mortality in the Western world. Studies of sortilin's influence on cardiovascular and metabolic diseases goes far beyond the genome-wide association studies that have revealed an association between cardiovascular diseases and the 1p13 locus that encodes sortilin. Emerging evidence suggests a significant role of sortilin in the pathogenesis of vascular and metabolic diseases; this includes type II diabetes mellitus via regulation of insulin resistance, atherosclerosis through arterial wall inflammation and calcification, and dysregulated lipoprotein metabolism. Sortilin is also known for its functional role in neurological disorders. It serves as a key receptor for cytokines, lipids, and enzymes and participates in pathological cargo loading to and trafficking of extracellular vesicles. This article provides a comprehensive review of sortilin's contributions to cardiovascular and metabolic diseases but focuses particularly on atherosclerosis. We summarize recent clinical findings that suggest that sortilin may be a cardiovascular risk biomarker and also discuss sortilin as a potential drug target. PMID- 29191925 TI - Inhalation of Fine Particulate Matter Impairs Endothelial Progenitor Cell Function Via Pulmonary Oxidative Stress. AB - OBJECTIVE: Exposure to fine particulate matter (PM2.5) air pollution is associated with the depletion of circulating endothelial progenitor cells (EPCs), as well as vascular injury and dysfunction. Nevertheless, it remains unclear whether PM2.5 exposure leads to significant impairments in EPC function. Hence, we studied the effects of PM2.5 on EPC-mediated recovery of vascular perfusion after hindlimb ischemia and examined the mechanisms whereby PM2.5 exposure affects EPC abundance and function. APPROACH AND RESULTS: In comparison with EPCs isolated from mice breathing filtered air, EPCs from mice exposed for 9 consecutive days (6 hours per day) to concentrated ambient PM2.5 (CAP) had defects in both proliferation and tube formation. However, CAP exposure of mice overexpressing extracellular superoxide dismutase (ecSOD-Tg) in the lungs did not affect EPC tube formation. Exposure to CAP also suppressed circulating EPC levels, VEGF (vascular endothelial growth factor)-stimulated aortic Akt phosphorylation, and plasma NO levels in wild-type but not in ecSOD-Tg mice. EPCs from CAP-exposed wild-type mice failed to augment basal recovery of hindlimb perfusion when injected into unexposed mice subjected to hindlimb ischemia; however, these deficits in recovery of hindlimb perfusion were absent when using EPCs derived from CAP-exposed ecSOD-Tg mice. The improved reparative function of EPCs from CAP-exposed ecSOD-Tg mice was also reflected by greater expression of Mmp-9 and Nos3 when compared with EPCs from CAP-exposed wild-type mice. CONCLUSIONS: Exposure to PM2.5 impairs EPC abundance and function and prevents EPC-mediated vascular recovery after hindlimb ischemia. This defect is attributed, in part, to pulmonary oxidative stress and was associated with vascular VEGF resistance and a decrement in NO bioavailability. PMID- 29191926 TI - Molecular Ultrasound Imaging of Junctional Adhesion Molecule A Depicts Acute Alterations in Blood Flow and Early Endothelial Dysregulation. AB - OBJECTIVE: The junctional adhesion molecule A (JAM-A) is physiologically located in interendothelial tight junctions and focally redistributes to the luminal surface of blood vessels under abnormal shear and flow conditions accompanying atherosclerotic lesion development. Therefore, JAM-A was evaluated as a target for molecularly targeted ultrasound imaging of transient endothelial dysfunction under acute blood flow variations. APPROACH AND RESULTS: Flow-dependent endothelial dysfunction was induced in apolipoprotein E-deficient mice (n=43) by carotid partial ligation. JAM-A expression was investigated by molecular ultrasound using antibody-targeted poly(n-butyl cyanoacrylate) microbubbles and validated with immunofluorescence. Flow disturbance and arterial remodeling were assessed using functional ultrasound. Partial ligation led to an immediate drop in perfusion at the ligated side and a direct compensatory increase at the contralateral side. This was accompanied by a strongly increased JAM-A expression and JAM-A-targeted microbubbles binding at the partially ligated side and by a moderate and temporary increase in the contralateral artery (~14* [P<0.001] and ~5* [P<0.001] higher than control, respectively), both peaking after 2 weeks. Subsequently, although JAM-A expression and JAM-A-targeted microbubbles binding persisted at a higher level at the partially ligated side, it completely normalized within 4 weeks at the contralateral side. CONCLUSIONS: Temporary blood flow variations induce endothelial rearrangement of JAM-A, which can be visualized using JAM-A-targeted microbubbles. Thus, JAM-A may be considered as a marker of acute endothelial activation and dysfunction. Its imaging may facilitate the early detection of cardiovascular risk areas, and it enables the therapeutic prevention of their progression toward an irreversible pathological state. PMID- 29191927 TI - Associations Between Residential Proximity to Traffic and Vascular Disease in a Cardiac Catheterization Cohort. AB - OBJECTIVE: Exposure to mobile source emissions is nearly ubiquitous in developed nations and is associated with multiple adverse health outcomes. There is an ongoing need to understand the specificity of traffic exposure associations with vascular outcomes, particularly in individuals with cardiovascular disease. APPROACH AND RESULTS: We performed a cross-sectional study using 2124 individuals residing in North Carolina, United States, who received a cardiac catheterization at the Duke University Medical Center. Traffic-related exposure was assessed via 2 metrics: (1) the distance between the primary residence and the nearest major roadway; and (2) location of the primary residence in regions defined based on local traffic patterns. We examined 4 cardiovascular disease outcomes: hypertension, peripheral arterial disease, the number of diseased coronary vessels, and recent myocardial infarction. Statistical models were adjusted for race, sex, smoking, type 2 diabetes mellitus, body mass index, hyperlipidemia, and home value. Results are expressed in terms of the odds ratio (OR). A 23% decrease in residential distance to major roadways was associated with higher prevalence of peripheral arterial disease (OR=1.29; 95% confidence interval, 1.08 1.55) and hypertension (OR=1.15; 95% confidence interval, 1.01-1.31). Associations with peripheral arterial disease were strongest in men (OR=1.42; 95% confidence interval, 1.17-1.74) while associations with hypertension were strongest in women (OR=1.21; 95% confidence interval, 0.99-1.49). Neither myocardial infarction nor the number of diseased coronary vessels were associated with traffic exposure. CONCLUSIONS: Traffic-related exposure is associated with peripheral arterial disease and hypertension while no associations are observed for 2 coronary-specific vascular outcomes.

PMID- 29191928 TI - Sustained Activation of Rho GTPases Promotes a Synthetic Pulmonary Artery Smooth Muscle Cell Phenotype in Neprilysin Null Mice. AB - OBJECTIVE: Pulmonary artery smooth muscle cells (PASMCs) from neprilysin (NEP) null mice exhibit a synthetic phenotype and increased activation of Rho GTPases compared with their wild-type counterparts. Although Rho GTPases are known to promote a contractile SMC phenotype, we hypothesize that their sustained activity decreases SM-protein expression in these cells. APPROACH AND RESULTS: PASMCs isolated from wild-type and NEP-/- mice were used to assess levels of SM-proteins (SM-actin, SM-myosin, SM22, and calponin) by Western blotting, and were lower in NEP-/- PASMCs compared with wild-type. Rac and Rho (ras homology family member) levels and activity were higher in NEP-/- PASMCs, and ShRNA to Rac and Rho restored SM-protein, and attenuated the enhanced migration and proliferation of NEP-/- PASMCs. SM-gene repressors, p-Elk-1, and Klf4 (Kruppel lung factor 4), were higher in NEP-/- PASMCs and decreased by shRNA to Rac and Rho. Costimulation of wild-type PASMCs with PDGF (platelet-derived growth factor) and the NEP substrate, ET-1 (endothelin-1), increased Rac and Rho activity, and decreased SM protein levels mimicking the NEP knock-out phenotype. Activation of Rac and Rho and downstream effectors was observed in lung tissue from NEP-/- mice and humans with chronic obstructive pulmonary disease. CONCLUSIONS: Sustained Rho activation in NEP-/- PASMCs is associated with a decrease in SM-protein levels and increased migration and proliferation. Inactivation of RhoGDI (Rho guanine dissociation inhibitor) and RhoGAP (Rho GTPase activating protein) by phosphorylation may contribute to prolonged activation of Rho in NEP-/- PASMCs. Rho GTPases may thus have a role in integration of signals between vasopeptides and growth factor receptors and could influence pathways that suppress SM-proteins to promote a synthetic phenotype.

AB - OBJECTIVE: To develop sex-specific and age-specific normative values for the nine Eurofit tests in European children and adolescents aged 9-17 years. METHODS: A systematic review was undertaken to identify papers that explicitly reported descriptive results for at least one of nine Eurofit tests (measuring balance, muscular strength, muscular endurance, muscular power, flexibility, speed, speed agility and cardiorespiratory fitness (CRF)) on children and adolescents. Data were included on apparently healthy (free from known disease/injury) children and adolescents aged 9-17 years. Following harmonisation for methodological variation where appropriate, pseudodata were generated using Monte Carlo simulation, with population-weighted sex-specific and age-specific normative centiles generated using the Lambda Mu Sigma (LMS) method. Sex-specific and age-specific differences were expressed as standardised differences in means, with the percentage of children and adolescents with healthy CRF estimated at the sex-age level. RESULTS: Norms were displayed as tabulated centiles and as smoothed centile curves for the nine Eurofit tests. The final dataset included 2 779 165 results on children and adolescents from 30 European countries, extracted from 98 studies. On average, 78% of boys (95% CI 72% to 85%) and 83% of girls (95% CI 71% to 96%) met the standards for healthy CRF, with the percentage meeting the standards decreasing with age. Boys performed substantially (standardised differences >0.2) better than girls on muscular strength, muscular power, muscular endurance, speed-agility and CRF tests, but worse on the flexibility test. Physical fitness generally improved at a faster rate in boys than in girls, especially during the teenage years. CONCLUSION: This study provides the largest and most geographically representative sex-specific and age-specific European normative values for children and adolescents, which have utility for health and fitness screening, profiling, monitoring and surveillance.

AB - With the introduction of hormonal substitution therapy in the 1950s, adrenal insufficiency (AI) has been turned into a manageable disease in pregnant women. In fact, in the light of glucocorticoid replacement therapy and improved obstetric care, it is realistic to expect good maternal and fetal outcomes in patients with AI. However, there are still a number of challenges such as establishing the diagnosis of AI in pregnant women and optimizing the treatment of AI and related comorbidities prior to as well as during pregnancy. Clinical and biochemical diagnoses of a new-onset AI may be challenging because of overlapping symptoms of normal pregnancy as well as pregnancy-induced changes in cortisol values. Physiological changes occurring during pregnancy should be taken into account while adjusting the substitution therapy. The high proportion of reported adrenal crisis in pregnant women with AI highlights persistent problems in this particular clinical situation. Due to the rarity of the disease, there is no prospective data-guiding management of pregnancy in patients with known AI. The aim of this review is to summarize the maternal and fetal outcomes based on recently published case reports in patients with AI and to suggest a practical approach to diagnose and manage AI in pregnancy.

PMID- 29191940 TI - Loss of cellular FLICE-inhibitory protein promotes acute cholestatic liver injury and inflammation from bile duct ligation. AB - Cholestatic liver injury results from impaired bile flow or metabolism and promotes hepatic inflammation and fibrogenesis. Toxic bile acids that accumulate in cholestasis induce apoptosis and contribute to early cholestatic liver injury, which is amplified by accompanying inflammation. The aim of the current study was to evaluate the role of the antiapoptotic caspase 8-homolog cellular FLICE inhibitory (cFLIP) protein during acute cholestatic liver injury. Transgenic mice exhibiting hepatocyte-specific deletion of cFLIP (cFLIP-/-) were used for in vivo and in vitro analysis of cholestatic liver injury using bile duct ligation (BDL) and the addition of bile acids ex vivo. Loss of cFLIP in hepatocytes promoted acute cholestatic liver injury early after BDL, which was characterized by a rapid release of proinflammatory and chemotactic cytokines (TNF, IL-6, IL-1beta, CCL2, CXCL1, and CXCL2), an increased presence of CD68+ macrophages and an influx of neutrophils in the liver, and resulting apoptotic and necrotic hepatocyte cell death. Mechanistically, liver injury in cFLIP-/- mice was aggravated by reactive oxygen species, and sustained activation of the JNK signaling pathway. In parallel, cytoprotective NF-kappaB p65, A20, and the MAPK p38 were inhibited. Increased injury in cFLIP-/- mice was accompanied by activation of hepatic stellate cells and profibrogenic regulators. The antagonistic caspase 8-homolog cFLIP is a critical regulator of acute, cholestatic liver injury. NEW & NOTEWORTHY The current paper explores the role of a classical modulator of hepatocellular apoptosis in early, cholestatic liver injury. These include activation of NF-kappaB and MAPK signaling, production of inflammatory cytokines, and recruitment of neutrophils in response to cholestasis. Because these signaling pathways are currently exploited in clinical trials for the treatment of nonalcoholic steatohepatitis and cirrhosis, the current data will help in the development of novel pharmacological options in these indications. PMID- 29191937 TI - Peroxynitrite preferentially oxidizes the dithiol redox motifs of protein disulfide isomerase. AB - Protein-disulfide isomerase (PDI) is a ubiquitous dithiol-disulfide oxidoreductase that performs an array of cellular functions, such as cellular signaling and responses to cell-damaging events. PDI can become dysfunctional by post-translational modifications, including those promoted by biological oxidants, and its dysfunction has been associated with several diseases in which oxidative stress plays a role. Because the kinetics and products of the reaction of these oxidants with PDI remain incompletely characterized, we investigated the reaction of PDI with the biological oxidant peroxynitrite. First, by determining the rate constant of the oxidation of PDI's redox-active Cys residues (Cys53 and Cys397) by hydrogen peroxide (k = 17.3 +/- 1.3 m-1 s-1 at pH 7.4 and 25 degrees C), we established that the measured decay of the intrinsic PDI fluorescence is appropriate for kinetic studies. The reaction of these PDI residues with peroxynitrite was considerably faster (k = (6.9 +/- 0.2) * 104 m-1 s-1), and both Cys residues were kinetically indistinguishable. Limited proteolysis, kinetic simulations, and MS analyses confirmed that peroxynitrite preferentially oxidizes the redox-active Cys residues of PDI to the corresponding sulfenic acids, which reacted with the resolving thiols at the active sites to produce disulfides (i.e. Cys53-Cys56 and Cys397-Cys400). A fraction of peroxynitrite, however, decayed to radicals that hydroxylated and nitrated other active-site residues (Trp52, Trp396, and Tyr393). Excess peroxynitrite promoted further PDI oxidation, nitration, inactivation, and covalent oligomerization. We conclude that these PDI modifications may contribute to the pathogenic mechanism of several diseases associated with dysfunctional PDI. PMID- 29191939 TI - Effects of hypothalamic leptin gene therapy on osteopetrosis in leptin-deficient mice. AB - Impaired resorption of cartilage matrix deposited during endochondral ossification is a defining feature of juvenile osteopetrosis. Growing, leptin deficient ob/ob mice exhibit a mild form of osteopetrosis. However, the extent to which the disease is (1) self-limiting and (2) reversible by leptin treatment is unknown. We addressed the first question by performing histomorphometric analysis of femurs in rapidly growing (2-month-old), slowly growing (4-month-old) and skeletally mature (6-month-old) wild-type (WT) and ob/ob male mice. Absent by 6 months of age in WT mice, cartilage matrix persisted to varying extents in distal femur epiphysis, metaphysis and diaphysis in ob/ob mice, suggesting that the osteopetrotic phenotype is not entirely self-limiting. To address the second question, we employed hypothalamic recombinant adeno-associated virus (rAAV) gene therapy to restore leptin signaling in ob/ob mice. Two-month-old mice were randomized to one of the three groups: (1) untreated control, (2) rAAV-Leptin or (3) control vector rAAV-green fluorescent protein and vectors injected intracerebroventricularly. Seven months later, rAAV-leptin-treated mice exhibited no cartilage in the metaphysis and greatly reduced cartilage in the epiphysis and diaphysis. At the cellular level, the reduction in cartilage was associated with increased bone turnover. These findings (1) support the concept that leptin is important for normal replacement of cartilage by bone, and (2) demonstrate that osteopetrosis in ob/ob mice is bone-compartment-specific and reversible by leptin at skeletal sites capable of undergoing robust bone turnover. PMID- 29191938 TI - International External Validation Study of the 2014 European Society of Cardiology Guidelines on Sudden Cardiac Death Prevention in Hypertrophic Cardiomyopathy (EVIDENCE-HCM). AB - BACKGROUND: Identification of people with hypertrophic cardiomyopathy (HCM) who are at risk of sudden cardiac death (SCD) and require a prophylactic implantable cardioverter defibrillator is challenging. In 2014, the European Society of Cardiology proposed a new risk stratification method based on a risk prediction model (HCM Risk-SCD) that estimates the 5-year risk of SCD. The aim was to externally validate the 2014 European Society of Cardiology recommendations in a geographically diverse cohort of patients recruited from the United States, Europe, the Middle East, and Asia. METHODS: This was an observational, retrospective, longitudinal cohort study. RESULTS: The cohort consisted of 3703 patients. Seventy three (2%) patients reached the SCD end point within 5 years of follow-up (5-year incidence, 2.4% [95% confidence interval {CI}, 1.9-3.0]). The validation study revealed a calibration slope of 1.02 (95% CI, 0.93-1.12), C index of 0.70 (95% CI, 0.68-0.72), and D-statistic of 1.17 (95% CI, 1.05-1.29). In a complete case analysis (n= 2147; 44 SCD end points at 5 years), patients with a predicted 5-year risk of <4% (n=1524; 71%) had an observed 5-year SCD incidence of 1.4% (95% CI, 0.8-2.2); patients with a predicted risk of >=6% (n=297; 14%) had an observed SCD incidence of 8.9% (95% CI, 5.96-13.1) at 5 years. For every 13 (297/23) implantable cardioverter defibrillator implantations in patients with an estimated 5-year SCD risk >=6%, 1 patient can potentially be saved from SCD. CONCLUSIONS: This study confirms that the HCM Risk-SCD model provides accurate prognostic information that can be used to target implantable cardioverter defibrillator therapy in patients at the highest risk of SCD. PMID- 29191941 TI - Genetic deletion of the circadian clock transcription factor BMAL1 and chronic alcohol consumption differentially alter hepatic glycogen in mice. AB - Multiple metabolic pathways exhibit time-of-day-dependent rhythms that are controlled by the molecular circadian clock. We have shown that chronic alcohol is capable of altering the molecular clock and diurnal oscillations in several elements of hepatic glycogen metabolism ( 19 , 44 ). Herein, we sought to determine whether genetic disruption of the hepatocyte clock differentially impacts hepatic glycogen content in chronic alcohol-fed mice. Male hepatocyte specific BMAL1 knockout (HBK) and littermate controls were fed control or alcohol containing diets for 5 wk to alter hepatic glycogen content. Glycogen displayed a significant diurnal rhythm in livers of control genotype mice fed the control diet. While rhythmic, alcohol significantly altered the diurnal oscillation of glycogen in livers of control genotype mice. The glycogen rhythm was mildly altered in livers of control-fed HBK mice. Importantly, glycogen content was arrhythmic in livers of alcohol-fed HBK mice. Consistent with these changes in hepatic glycogen content, we observed that some glycogen and glucose metabolism genes were differentially altered by chronic alcohol consumption in livers of HBK and littermate control mice. Diurnal rhythms in glycogen synthase (mRNA and protein) were significantly altered by alcohol feeding and clock disruption. Alcohol consumption significantly altered Gck, Glut2, and Ppp1r3g rhythms in livers of control genotype mice, with diurnal rhythms of Pklr, Glut2, Ppp1r3c, and Ppp1r3g further disrupted (dampened or arrhythmic) in livers of HBK mice. Taken together, these findings show that chronic alcohol consumption and hepatocyte clock disruption differentially influence the diurnal rhythm of glycogen and various key glycogen metabolism-related genes in the liver. NEW & NOTEWORTHY We report that circadian clock disruption exacerbates alcohol-mediated alterations in hepatic glycogen. We observed differential responsiveness in diurnal rhythms of glycogen and glycogen metabolism genes and proteins in livers of hepatocyte-specific BMAL1 knockout and littermate control mice fed alcohol. Our findings provide new insights into potential mechanisms by which alcohol alters glycogen, an important energy source for liver and other organs. PMID- 29191942 TI - beta-PIX plays an important role in regulation of intestinal epithelial restitution by interacting with GIT1 and Rac1 after wounding. AB - Early gut mucosal restitution is a process by which intestinal epithelial cells (IECs) migrate over the wounded area, and its defective regulation occurs commonly in various critical pathological conditions. This rapid reepithelialization is mediated by different activating small GTP-binding proteins, but the exact mechanism underlying this process remains largely unknown. Recently, it has been reported that interaction between p21-activated kinase-interacting exchange factor (beta-PIX) and G protein-coupled receptor kinase-interacting protein 1 (GIT1) activates small GTPases and plays an important role in the regulation of cell motility. Here, we show that induced association of beta-PIX with GIT1 is essential for the stimulation of IEC migration after wounding by activating Rac1. Levels of beta-PIX and GIT1 proteins and their association in differentiated IECs (line of IEC-Cdx2L1) were much higher than those observed in undifferentiated IECs (line of IEC-6), which was associated with an increase in IEC migration after wounding. Decreased levels of endogenous beta-PIX by its gene-silencing destabilized beta-PIX/GIT1 complexes, repressed Rac1 activity and inhibited cell migration over the wounded area. In contrast, ectopic overexpression of beta-PIX increased the levels of beta PIX/GIT1 complexes, stimulated Rac1 activity, and enhanced intestinal epithelial restitution. Increased levels of cellular polyamines also stimulated beta PIX/GIT1 association, increased Rac1 activity, and promoted the epithelial restitution. Moreover, polyamine depletion decreased cellular abundances of beta PIX/GIT1 complex and repressed IEC migration after wounding, which was rescued by ectopic overexpression of beta-PIX or GIT1. These results indicate that beta PIX/GIT1/Rac1 association is necessary for stimulation of IEC migration after wounding and that this signaling pathway is tightly regulated by cellular polyamines. NEW & NOTEWORTHY Our current study demonstrates that induced association of beta-PIX with GIT1 is essential for the stimulation of intestinal epithelial restitution by activating Rac1, and this signaling pathway is tightly regulated by cellular polyamines.

PMID- 29191945 TI - Thrombopoietin mutation in congenital amegakaryocytic thrombocytopenia treatable with romiplostim. AB - Congenital amegakaryocytic thrombocytopenia (CAMT) is an inherited disorder characterized at birth by thrombocytopenia with reduced megakaryocytes, which evolves into generalized bone marrow aplasia during childhood. Although CAMT is genetically heterogeneous, mutations of MPL, the gene encoding for the receptor of thrombopoietin (THPO), are the only known disease-causing alterations. We identified a family with three children affected with CAMT caused by a homozygous mutation (p.R119C) of the THPO gene. Functional studies showed that p.R119C affects not only ability of the cytokine to stimulate MPL but also its release, which is consistent with the relatively low serum THPO levels measured in patients. In all the three affected children, treatment with the THPO-mimetic romiplostim induced trilineage hematological responses, remission of bleeding and infections, and transfusion independence, which were maintained after up to 6.5 years of observation. Recognizing patients with THPO mutations among those with juvenile bone marrow failure is essential to provide them with appropriate substitutive therapy and prevent the use of invasive and unnecessary treatments, such as hematopoietic stem cell transplantation or immunosuppression.

PMID- 29191947 TI - A proteomic network approach across the ALS-FTD disease spectrum resolves clinical phenotypes and genetic vulnerability in human brain. AB - Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are neurodegenerative diseases with overlap in clinical presentation, neuropathology, and genetic underpinnings. The molecular basis for the overlap of these disorders is not well established. We performed a comparative unbiased mass spectrometry based proteomic analysis of frontal cortical tissues from postmortem cases clinically defined as ALS, FTD, ALS and FTD (ALS/FTD), and controls. We also included a subset of patients with the C9orf72 expansion mutation, the most common genetic cause of both ALS and FTD Our systems-level analysis of the brain proteome integrated both differential expression and co-expression approaches to assess the relationship of these differences to clinical and pathological phenotypes. Weighted co-expression network analysis revealed 15 modules of co expressed proteins, eight of which were significantly different across the ALS FTD disease spectrum. These included modules associated with RNA binding proteins, synaptic transmission, and inflammation with cell-type specificity that showed correlation with TDP-43 pathology and cognitive dysfunction. Modules were also examined for their overlap with TDP-43 protein-protein interactions, revealing one module enriched with RNA-binding proteins and other causal ALS genes that increased in FTD/ALS and FTD cases. A module enriched with astrocyte and microglia proteins was significantly increased in ALS cases carrying the C9orf72 mutation compared to sporadic ALS cases, suggesting that the genetic expansion is associated with inflammation in the brain even without clinical evidence of dementia. Together, these findings highlight the utility of integrative systems-level proteomic approaches to resolve clinical phenotypes and genetic mechanisms underlying the ALS-FTD disease spectrum in human brain.

AB - Chronic obstructive pulmonary disease (COPD) airways are characterised by thickening of airway smooth muscle, partly due to airway smooth muscle cell (ASMC) hyperplasia. Metabolic reprogramming involving increased glycolysis and glutamine catabolism supports the biosynthetic and redox balance required for cellular growth. We examined whether COPD ASMCs show a distinct metabolic phenotype that may contribute to increased growth.We performed an exploratory intracellular metabolic profile analysis of ASMCs from healthy nonsmokers, healthy smokers and COPD patients, under unstimulated or growth conditions of transforming growth factor (TGF)-beta and fetal bovine serum (FBS).COPD ASMCs showed impaired energy balance and accumulation of the glycolytic product lactate, glutamine, fatty acids and amino acids compared to controls in unstimulated and growth conditions. Fatty acid oxidation capacity was reduced under unstimulated conditions. TGF-beta/FBS-stimulated COPD ASMCs showed restoration of fatty acid oxidation capacity, upregulation of the pentose phosphate pathway product ribose-5-phosphate and of nucleotide biosynthesis intermediates, and increased levels of the glutamine catabolite glutamate. In addition, TGF-beta/FBS-stimulated COPD ASMCs showed a higher reduced-to-oxidised glutathione ratio and lower mitochondrial oxidant levels. Inhibition of glycolysis and glutamine depletion attenuated TGF-beta/FBS-stimulated growth of COPD ASMCs.Changes in glycolysis, glutamine and fatty acid metabolism may lead to increased biosynthesis and redox balance, supporting COPD ASMC growth. PMID- 29191951 TI - Predictors of sleepiness in obstructive sleep apnoea at baseline and after 6 months of continuous positive airway pressure therapy. AB - We evaluated factors associated with subjective and objective sleepiness at baseline and after 6 months of continuous positive airway pressure (CPAP) therapy in patients with obstructive sleep apnoea (OSA).We analysed data from the Apnoea Positive Pressure Long-term Efficacy Study (APPLES), a prospective 6-month multicentre randomised controlled trial with 1105 subjects with OSA, 558 of who were randomised to active CPAP. Epworth sleepiness scale (ESS) scores and the mean sleep latency (MSL) on the maintenance of wakefulness test at baseline and after 6 months of CPAP therapy were recorded.Excessive sleepiness (ESS score >10) was present in 543 (49.1%) participants. Younger age, presence of depression and higher apnoea-hypopnoea index were all associated with higher ESS scores and lower MSL. Randomisation to the CPAP group was associated with lower odds of sleepiness at 6 months. The prevalence of sleepiness was significantly lower in those using CPAP >4 h.night-1versus using CPAP <=4 h.night-1 Among those with good CPAP adherence, those with ESS >10 at baseline had significantly higher odds (OR 8.2, p<0.001) of persistent subjective sleepiness.Lower average nightly CPAP use and presence of sleepiness at baseline were independently associated with excessive subjective and objective sleepiness after 6 months of CPAP therapy. PMID- 29191952 TI - European Respiratory Society statement: diagnosis and treatment of pulmonary disease in alpha1-antitrypsin deficiency. AB - alpha1-antitrypsin deficiency (AATD) is the most common hereditary disorder in adults. It is associated with an increased risk of developing pulmonary emphysema and liver disease. The pulmonary emphysema in AATD is strongly linked to smoking, but even a proportion of never-smokers develop progressive lung disease. A large proportion of individuals affected remain undiagnosed and therefore without access to appropriate care and treatment.The most recent international statement on AATD was published by the American Thoracic Society and the European Respiratory Society in 2003. Since then there has been a continuous development of novel, more accurate and less expensive genetic diagnostic methods. Furthermore, new outcome parameters have been developed and validated for use in clinical trials and a new series of observational and randomised clinical trials have provided more evidence concerning the efficacy and safety of augmentation therapy, the only specific treatment available for the pulmonary disease associated with AATD.As AATD is a rare disease, it is crucial to organise national and international registries and collect information prospectively about the natural history of the disease. Management of AATD patients must be supervised by national or regional expert centres and inequalities in access to therapies across Europe should be addressed.

PMID- 29191953 TI - Surfactant protein D is a causal risk factor for COPD: results of Mendelian randomisation. AB - Surfactant protein D (SP-D) is produced primarily in the lung and is involved in regulating pulmonary surfactants, lipid homeostasis and innate immunity. Circulating SP-D levels in blood are associated with chronic obstructive pulmonary disease (COPD), although causality remains elusive.In 4061 subjects with COPD, we identified genetic variants associated with serum SP-D levels. We then determined whether these variants affected lung tissue gene expression in 1037 individuals. A Mendelian randomisation framework was then applied, whereby serum SP-D-associated variants were tested for association with COPD risk in 11 157 cases and 36 699 controls and with 11 years decline of lung function in the 4061 individuals.Three regions on chromosomes 6 (human leukocyte antigen region), 10 (SFTPD gene) and 16 (ATP2C2 gene) were associated with serum SP-D levels at genome-wide significance. In Mendelian randomisation analyses, variants associated with increased serum SP-D levels decreased the risk of COPD (estimate 0.19, p=6.46*10-03) and slowed the lung function decline (estimate=0.0038, p=7.68*10-3).Leveraging genetic variation effect on protein, lung gene expression and disease phenotypes provided novel insights into SP-D biology and established a causal link between increased SP-D levels and protection against COPD risk and progression. SP-D represents a very promising biomarker and therapeutic target for COPD. PMID- 29191955 TI - Mortality: a neglected outcome in OCS-treated severe asthma.

AB - Mesenchymal stromal cells have emerged as potential candidates for cell-based therapies to modulate the immune response in organ transplantation and repair tissues after acute or chronic injury. Preclinical studies have shown convincingly in rodent models that mesenchymal stromal cells can prolong solid organ graft survival and that they can induce immune tolerance, accelerate recovery from AKI, and promote functional improvement in chronic nephropathies. Multiple complex properties of the cells, including immunomodulatory, anti inflammatory, and proregenerative effects, seem to contribute. The promising preclinical studies have encouraged investigators to explore the safety, tolerability, and efficacy of mesenchymal stromal cell-based therapy in pilot clinical trials, including those for bone marrow and solid organ transplantation, autoimmune diseases, and tissue and organ repair. Here, we review the available data on culture-expanded mesenchymal stromal cells tested in renal transplantation, AKI, and CKD. We also briefly discuss the relevant issues that must be addressed to ensure rigorous assessment of the safety and efficacy of mesenchymal stromal cell therapies to allow the translation of this research into the practice of clinical nephrology. PMID- 29191960 TI - Magnesium and Risk of Hip Fracture among Patients Undergoing Hemodialysis. AB - Magnesium is an essential mineral for bone metabolism. However, little is known about the relationship between magnesium and the risk of fractures. In this cohort study, we elucidated the association between serum magnesium level and the risk of incident hip fracture among patients undergoing hemodialysis. We identified 113,683 patients undergoing hemodialysis with no history of hip fracture from a nation-wide database of patients undergoing dialysis in Japan. During a 2-year follow-up, a total of 2305 (2%) new hip fractures occurred. The crude incidence rate was significantly higher among patients in the lower quartiles of serum magnesium levels (2.63%, 2.08%, 1.76%, and 1.49% in Q1-Q4, respectively; P<0.001 for trend). The range of serum magnesium levels (in milligrams per deciliter) in each quartile was as follows: Q1, <2.3; Q2, 2.4-2.6; Q3, 2.7-2.8, and Q4, >2.9. After adjustment for demographic and clinical factors, patients in Q1 had a 1.23-fold higher risk for hip fracture than those in Q4 (95% confidence interval, 1.06 to 1.44; P<0.01). Similarly, an inverse probability weighting analysis showed an increased risk of hip fracture among patients in the lower magnesium quartiles. We did not observe significant effect modifications in subgroup analyses. The population-attributable fraction of serum magnesium level for incident hip fractures was 13.7% (95% confidence interval, 3.7% to 22.7%), which was much higher than that of serum calcium, serum phosphate, and parathyroid hormone levels. Thus, mild hypermagnesemia is associated with a lower risk of hip fracture among patients undergoing hemodialysis. PMID- 29191961 TI - Intragraft Molecular Pathways Associated with Tolerance Induction in Renal Transplantation. AB - The modern immunosuppression regimen has greatly improved short-term allograft outcomes but not long-term allograft survival. Complications associated with immunosuppression, specifically nephrotoxicity and infection risk, significantly affect graft and patient survival. Inducing and understanding pathways underlying clinical tolerance after transplantation are, therefore, necessary. We previously showed full donor chimerism and immunosuppression withdrawal in highly mismatched allograft recipients using a bioengineered stem cell product (FCRx). Here, we evaluated the gene expression and microRNA expression profiles in renal biopsy samples from tolerance-induced FCRx recipients, paired donor organs before implant, and subjects under standard immunosuppression (SIS) without rejection and with acute rejection. Unlike allograft samples showing acute rejection, samples from FCRx recipients did not show upregulation of T cell- and B cell mediated rejection pathways. Gene expression pathways differed slightly between FCRx samples and the paired preimplantation donor organ samples, but most of the functional gene networks overlapped. Notably, compared with SIS samples, FCRx samples showed upregulation of genes involved in pathways, like B cell receptor signaling. Additionally, prediction analysis showed inhibition of proinflammatory regulators and activation of anti-inflammatory pathways in FCRx samples. Furthermore, integrative analyses (microRNA and gene expression profiling from the same biopsy sample) identified the induction of regulators with demonstrated roles in the downregulation of inflammatory pathways and maintenance of tissue homeostasis in tolerance-induced FCRx samples compared with SIS samples. This pilot study highlights the utility of molecular intragraft evaluation of pathways related to FCRx-induced tolerance and the use of integrative analyses for identifying upstream regulators of the affected downstream molecular pathways.

AB - Nontypeable Haemophilus influenzae (NTHi), one of the most common acute otitis media (OM) pathogens, is postulated to promote middle-ear epithelial remodeling in the progression of OM from acute to chronic. The goal of this study was to examine early quantitative proteomic secretome effects of NTHi lysate exposure in a human middle-ear epithelial cell (HMEEC) line. NTHi lysates were used to stimulate HMEEC, and conditional quantitative stable isotope labeling with amino acids in cell culture of cell secretions was performed. Mass spectrometry analysis identified 766 proteins across samples. Of interest, several heterogeneous nuclear ribonucleoproteins (hnRNPs) were regulated by NTHi lysate treatment, especially hnRNP A2B1 and hnRNP Q, known to be implicated in microRNA (miRNA) packaging in exosomes. After purification, the presence of exosomes in HMEEC secretions was characterized by dynamic light scattering (<100 nm), transmission electron microscopy, and CD63/heat shock protein 70 positivity. hnRNP A2B1 and hnRNP Q were confirmed to be found in exosomes by Western blot and proteomic analysis. Finally, exosomal miRNA content comprised 110 unique miRNAs, with 5 found to be statistically induced by NTHi lysate (miR-378a-3p + miR-378i, miR-200a-3p, miR-378g, miR30d-5p, and miR-222-3p), all known to target innate immunity genes. This study demonstrates that NTHi lysates promote release of miRNA-laden exosomes from middle-ear epithelium in vitro. -Val, S., Krueger, A., Poley, M., Cohen, A., Brown, K., Panigrahi, A., Preciado, D.

AB - Static apnea provides a unique model that combines transient hypertension, hypercapnia, and severe hypoxemia. With apnea durations exceeding 5 min, the purpose of the present study was to determine how that affects cerebral free radical formation and the corresponding implications for brain structure and function. Measurements were obtained before and following a maximal apnea in 14 divers with transcerebral exchange kinetics, measured as the product of global cerebral blood flow (duplex ultrasound) and radial arterial to internal jugular venous concentration differences ( a-vD). Apnea increased the systemic (arterial) and, to a greater extent, the regional (jugular venous) concentration of the ascorbate free radical, resulting in a shift from net cerebral uptake to output ( P < 0.05). Peroxidation (lipid hydroperoxides, LDL oxidation), NO bioactivity, and S100beta were correspondingly enhanced ( P < 0.05), the latter interpreted as minor and not a pathologic disruption of the blood-brain barrier. However, those changes were insufficient to cause neuronal-parenchymal damage confirmed by the lack of change in the a-vD of neuron-specific enolase and human myelin basic protein ( P > 0.05). Collectively, these observations suggest that increased cerebral oxidative stress following prolonged apnea in trained divers may reflect a functional physiologic response, rather than a purely maladaptive phenomenon.

AB - One of the hallmarks of the tauopathies, which include the neurodegenerative disorders, such as Alzheimer disease (AD), corticobasal degeneration, frontotemporal dementia, and progressive supranuclear palsy (PSP), is the abnormal accumulation of post-translationally modified, insoluble tau. The result is a loss of neurons, decreased mental function, and complete dependence of patients on others. Aggregation of tau, which under physiologic conditions is a highly soluble protein, is thought to be central to the pathogenesis of these diseases. Indeed one of the strongest lines of evidence is the MAPT gene polymorphisms that lead to the familial forms of tauopathy. Extensive research in animal models over the years has contributed some of the most important findings regarding the pathogenesis of these diseases. Despite this, the precise molecular mechanisms that lead to abnormal tau folding, accumulation, and spreading remain unknown. Owing to the fact that most of the biochemical pathways are conserved, Caenorhabditis elegans provides an alternative approach to identify cellular mechanisms and druggable genes that operate in such disorders. Many human genes implicated in neurodegenerative diseases have counterparts in C. elegans, making it an excellent model in which to study their pathogenesis. In this article, we review some of the important findings gained from C. elegans tauopathy models. Pir, G. J., Choudhary, B., Mandelkow, E. Caenorhabditiselegans models of tauopathy.

AB - INTRODUCTION: The 'Safety in Numbers' (SiN) phenomenon refers to a decline of injury risk per time or distance exposed as use of a mode increases. It has been demonstrated for cycling using cross-sectional data, but little evidence exists as to whether the effect applies longitudinally -that is, whether changes in cycling levels correlate with changes in per-cyclist injury risks. METHODS: This paper examines cross-sectional and longitudinal SiN effects in 202 local authorities in Britain, using commuting data from 1991, 2001 and 2011 censuses plus police -recorded data on 'killed and seriously injured' (KSI) road traffic injuries. We modelled a log-linear relationship between number of injuries and number of cycle commuters. Second, we conducted longitudinal analysis to examine whether local authorities where commuter cycling increased became safer (and vice versa). RESULTS: The paper finds a cross-sectional SiN effect exists in the 1991, 2001 and 2011 censuses. The longitudinal analysis also found a SiN effect, that is, places where cycling increased were more likely to become safer than places where it had declined. Finally, these longitudinal results are placed in the context of changes in pedestrian, cyclist and motorist safety. While between 1991 and 2001 all modes saw declines in KSI risk (37% for pedestrians, 36% for cyclists and 27% for motor vehicle users), between 2001 and 2011 pedestrians and motorists saw even more substantial declines (41% and 49%), while risk for cyclists increased by 4%. CONCLUSION: The SiN mechanism does seem to operate longitudinally as well as cross-sectionally. However, at a national level between 2001-11 it co-existed with an increase in cyclist injury risk both in absolute terms and in relation to other modes. PMID- 29191969 TI - Olaratumab Exerts Antitumor Activity in Preclinical Models of Pediatric Bone and Soft Tissue Tumors through Inhibition of Platelet-Derived Growth Factor Receptor alpha. AB - Purpose: Platelet-derived growth factor receptor alpha (PDGFRalpha) is implicated in several adult and pediatric malignancies, where activated signaling in tumor cells and/or cells within the microenvironment drive tumorigenesis and disease progression. Olaratumab (LY3012207/IMC-3G3) is a human mAb that exclusively binds to PDGFRalpha and recently received accelerated FDA approval and conditional EMA approval for treatment of advanced adult sarcoma patients in combination with doxorubicin. In this study, we investigated olaratumab in preclinical models of pediatric bone and soft tissue tumors.Experimental Design: PDGFRalpha expression was evaluated by qPCR and Western blot analysis. Olaratumab was investigated in in vitro cell proliferation and invasion assays using pediatric osteosarcoma and rhabdoid tumor cell lines. In vivo activity of olaratumab was assessed in preclinical mouse models of pediatric osteosarcoma and malignant rhabdoid tumor.Results:In vitro olaratumab treatment of osteosarcoma and rhabdoid tumor cell lines reduced proliferation and inhibited invasion driven by individual platelet-derived growth factors (PDGFs) or serum. Furthermore, olaratumab delayed primary tumor growth in mouse models of pediatric osteosarcoma and malignant rhabdoid tumor, and this activity was enhanced by combination with either doxorubicin or cisplatin.Conclusions: Overall, these data indicate that olaratumab, alone and in combination with standard of care, blocks the growth of some preclinical PDGFRalpha-expressing pediatric bone and soft tissue tumor models.

AB - Purpose: Neuroblastoma displays important clinical and genetic heterogeneity, with emergence of new mutations at tumor progression.Experimental Design: To study clonal evolution during treatment and follow-up, an innovative method based on circulating cell-free DNA (cfDNA) analysis by whole-exome sequencing (WES) paired with target sequencing was realized in sequential liquid biopsy samples of 19 neuroblastoma patients.Results: WES of the primary tumor and cfDNA at diagnosis showed overlap of single-nucleotide variants (SNV) and copy number alterations, with 41% and 93% of all detected alterations common to the primary neuroblastoma and cfDNA. CfDNA WES at a second time point indicated a mean of 22 new SNVs for patients with progressive disease. Relapse-specific alterations included genes of the MAPK pathway and targeted the protein kinase A signaling pathway. Deep coverage target sequencing of intermediate time points during treatment and follow-up identified distinct subclones. For 17 seemingly relapse specific SNVs detected by cfDNA WES at relapse but not tumor or cfDNA WES at diagnosis, deep coverage target sequencing detected these alterations in minor subclones, with relapse-emerging SNVs targeting genes of neuritogenesis and cell cycle. Furthermore a persisting, resistant clone with concomitant disappearance of other clones was identified by a mutation in the ubiquitin protein ligase HERC2Conclusions: Modelization of mutated allele fractions in cfDNA indicated distinct patterns of clonal evolution, with either a minor, treatment-resistant clone expanding to a major clone at relapse, or minor clones collaborating toward tumor progression. Identification of treatment-resistant clones will enable development of more efficient treatment strategies. Clin Cancer Res; 24(4); 939 49. (c)2017 AACR.

PMID- 29191972 TI - Mutations in Homologous Recombination Genes and Outcomes in Ovarian Carcinoma Patients in GOG 218: An NRG Oncology/Gynecologic Oncology Group Study. AB - Purpose: We hypothesized that mutations in homologous recombination repair (HRR) genes beyond BRCA1 and BRCA2 improve outcomes for ovarian carcinoma patients treated with platinum therapy and would impact the relative benefit of adding prolonged bevacizumab.Experimental Design: We sequenced DNA from blood and/or neoplasm from 1,195 women enrolled in GOG-0218, a randomized phase III trial in advanced ovarian carcinoma of bevacizumab added to carboplatin and paclitaxel. Defects in HRR were defined as damaging mutations in 16 genes. Proportional hazards models were used to estimate relative hazards for progression-free survival (PFS) and overall survival (OS).Results: Of 1,195 women with ovarian carcinoma, HRR mutations were identified in 307 (25.7%). Adjusted hazards for progression and death compared with those without mutations were lower for women with non-BRCA HRR mutations [HR = 0.73; 95% confidence interval (CI), 0.57-0.94; P = 0.01 for PFS; HR = 0.67; 95% CI, 0.50-0.90; P = 0.007 for OS] and BRCA1 mutations (HR = 0.80; 95% CI, 0.66-0.97; P = 0.02 for PFS; HR = 0.74; 95% CI, 0.59-0.94; P = 0.01 for OS) and were lowest for BRCA2 mutations (HR = 0.52; 95% CI, 0.40-0.67; P < 0.0001 for PFS; HR = 0.36; 95% CI, 0.25-0.53; P < 0.0001 for OS). A test of interaction showed no difference in the effect of bevacizumab on PFS between cases with and without mutations.Conclusions: HRR mutations, including non-BRCA genes, significantly prolong PFS and OS in ovarian carcinoma and should be stratified for in clinical trials. The benefit of adding bevacizumab was not significantly modified by mutation status. Clin Cancer Res; 24(4); 777-83. (c)2017 AACR. PMID- 29191973 TI - Blocking the Feedback Loop between Neuroendocrine Differentiation and Macrophages Improves the Therapeutic Effects of Enzalutamide (MDV3100) on Prostate Cancer. AB - Purpose: Androgen deprivation therapy (ADT), including enzalutamide, induces resistance in prostate cancer; ADT resistance is associated with neuroendocrine differentiation (NED) and tumor-associated macrophages (TAM). This study aimed to investigate the association between enzalutamide-induced NED and TAMs and its mechanism.Experimental Design: The association between enzalutamide-induced NED and TAMs was investigated by IHC using prostate cancer tissues, enzalutamide resistant mouse xenografts, and a coculture system. The underlying mechanisms were assessed using in vitro cytokine antibody arrays, ELISAs, chromatin immunoprecipitation, and other methods. An orthotopic prostate cancer mouse model was established to evaluate the in vivo effects of combined IL6 receptor (IL6R) and high mobility group box 1 (HMGB1) inhibition on enzalutamide resistance.Results: High CD163 expression was observed in ADT-treated prostate cancer or castration-resistant prostate cancer (CRPC) tissues with high levels of neuron-specific enolase (NSE) and chromogranin A (CHGA) and in enzalutamide resistant xenografts, indicating the crucial roles of NED and TAMs in enzalutamide resistance. Specifically, enzalutamide-induced HMGB1 expression facilitated TAM recruitment and polarization and drove NED via beta-catenin stabilization. HMGB1-activated TAMs secreted IL6 to augment enzalutamide-induced NED and directly promote HMGB1 transcription via STAT3. Finally, inhibition of the IL6/STAT3 pathway by tocilizumab combined with HMGB1 knockdown inhibited enzalutamide-induced resistance in an orthotopic prostate cancer mouse model.Conclusions: Enzalutamide elevates HMGB1 levels, which recruits and activates TAMs. Moreover, IL6 secreted by HMGB1-activated TAMs facilitates the enzalutamide-induced NED of prostate cancer, forming a positive feedback loop between NED in prostate cancer and TAMs. The combined inhibition of IL6R and HMGB1 may serve as a new treatment for enzalutamide resistance in patients with advanced or metastatic prostate cancer.

AB - Shigella deploys a unique mechanism to manipulate macrophage pyroptosis by delivering the IpaH7.8 E3 ubiquitin ligase via its type III secretion system. IpaH7.8 ubiquitinates glomulin (GLMN) and elicits its degradation, thereby inducing inflammasome activation and pyroptotic cell death of macrophages. Here, we show that GLMN specifically binds cellular inhibitor of apoptosis proteins 1 and 2 (cIAP1 and cIAP2), members of the inhibitor of apoptosis (IAP) family of RING-E3 ligases, which results in reduced E3 ligase activity, and consequently inflammasome-mediated death of macrophages. Importantly, reducing the levels of GLMN in macrophages via IpaH7.8, or siRNA-mediated knockdown, enhances inflammasome activation in response to infection by Shigella, Salmonella, or Pseudomonas, stimulation with NLRP3 inflammasome activators (including SiO2, alum, or MSU), or stimulation of the AIM2 inflammasome by poly dA:dT GLMN binds specifically to the RING domain of both cIAPs, which inhibits their self ubiquitination activity. These findings suggest that GLMN is a negative regulator of cIAP-mediated inflammasome activation, and highlight a unique Shigella stratagem to kill macrophages, promoting severe inflammation. PMID- 29191980 TI - Prior automatic posture and activity identification improves physical activity energy expenditure prediction from hip-worn triaxial accelerometry. AB - Accelerometry is increasingly used to quantify physical activity (PA) and related energy expenditure (EE). Linear regression models designed to derive PAEE from accelerometry-counts have shown their limits, mostly due to the lack of consideration of the nature of activities performed. Here we tested whether a model coupling an automatic activity/posture recognition (AAR) algorithm with an activity-specific count-based model, developed in 61 subjects in laboratory conditions, improved PAEE and total EE (TEE) predictions from a hip-worn triaxial accelerometer (ActigraphGT3X+) in free-living conditions. Data from two independent subject groups of varying body mass index and age were considered: 20 subjects engaged in a 3-h urban-circuit, with activity-by-activity reference PAEE from combined heart-rate and accelerometry monitoring (Actiheart); and 56 subjects involved in a 14-day trial, with PAEE and TEE measured using the doubly labeled water method. PAEE was estimated from accelerometry using the activity specific model coupled to the AAR algorithm (AAR model), a simple linear model (SLM), and equations provided by the companion-software of used activity-devices (Freedson and Actiheart models). AAR-model predictions were in closer agreement with selected references than those from other count-based models, both for PAEE during the urban-circuit (RMSE = 6.19 vs 7.90 for SLM and 9.62 kJ/min for Freedson) and for EE over the 14-day trial, reaching Actiheart performances in the latter (PAEE: RMSE = 0.93 vs. 1.53 for SLM, 1.43 for Freedson, 0.91 MJ/day for Actiheart; TEE: RMSE = 1.05 vs. 1.57 for SLM, 1.70 for Freedson, 0.95 MJ/day for Actiheart). Overall, the AAR model resulted in a 43% increase of daily PAEE variance explained by accelerometry predictions. NEW & NOTEWORTHY Although triaxial accelerometry is widely used in free-living conditions to assess the impact of physical activity energy expenditure (PAEE) on health, its precision and accuracy are often debated. Here we developed and validated an activity specific model which, coupled with an automatic activity-recognition algorithm, improved the variance explained by the predictions from accelerometry counts by 43% of daily PAEE compared with models relying on a simple relationship between accelerometry counts and EE. PMID- 29191977 TI - The tumor suppressor Brat controls neuronal stem cell lineages by inhibiting Deadpan and Zelda. AB - The TRIM-NHL protein Brain tumor (Brat) acts as a tumor suppressor in the Drosophila brain, but how it suppresses tumor formation is not completely understood. Here, we combine temperature-controlled brat RNAi with transcriptome analysis to identify the immediate Brat targets in Drosophila neuroblasts. Besides the known target Deadpan (Dpn), our experiments identify the transcription factor Zelda (Zld) as a critical target of Brat. Our data show that Zld is expressed in neuroblasts and required to allow re-expression of Dpn in transit-amplifying intermediate neural progenitors. Upon neuroblast division, Brat is enriched in one daughter cell where its NHL domain directly binds to specific motifs in the 3'UTR of dpn and zld mRNA to mediate their degradation. In brat mutants, both Dpn and Zld continue to be expressed, but inhibition of either transcription factor prevents tumorigenesis. Our genetic and biochemical data indicate that Dpn inhibition requires higher Brat levels than Zld inhibition and suggest a model where stepwise post-transcriptional inhibition of distinct factors ensures sequential generation of fates in a stem cell lineage. PMID- 29191981 TI - Impact of training state on fasting-induced regulation of adipose tissue metabolism in humans. AB - Recruitment of fatty acids from adipose tissue is increased during fasting. However, the molecular mechanisms behind fasting-induced metabolic regulation in human adipose tissue and the potential impact of training state in this are unknown. Therefore the aim of the present study was to investigate 1) fasting induced regulation of lipolysis and glyceroneogenesis in human adipose tissue as well as 2) the impact of training state on basal oxidative capacity and fasting induced metabolic regulation in human adipose tissue. Untrained [maximal oxygen uptake (Vo2max) < 45 ml.min-1.kg-1] and trained subjects (Vo2max > 55 ml.min-1.kg 1) fasted for 36 h, and abdominal subcutaneous adipose tissue biopsies were obtained 2, 12, 24, and 36 h after a standardized meal. Adipose tissue oxidative phosphorylation complexes, phosphoenolpyruvate carboxykinase, and pyruvate dehydrogenase (PDH)-E1alpha protein as well as PDH kinase (PDK) 2, PDK4, and PDH phosphatase 2 mRNA content were higher in trained subjects than in untrained subjects. In addition, trained subjects had higher adipose tissue hormone sensitive lipase Ser660 phosphorylation and adipose triglyceride lipase protein content as well as higher plasma free fatty acid concentration than untrained subjects during fasting. Moreover, adipose tissue PDH phosphorylation increased with fasting only in trained subjects. Taken together, trained subjects seem to possess higher basal adipose tissue oxidative capacity as well as higher capacity for regulation of lipolysis and for providing substrate for glyceroneogenesis in adipose tissue during fasting than untrained subjects. NEW & NOTEWORTHY This study shows for the first time higher protein content of lipolytic enzymes and higher oxidative phosphorylation protein in adipose tissue from trained subjects than from untrained subjects during fasting. Furthermore, trained subjects had higher capacity for adipose tissue glyceroneogenesis than untrained subjects. PMID- 29191982 TI - Exercise-induced diaphragm fatigue in a Paralympic champion rower with spinal cord injury. AB - The aim of this case report was to determine whether maximal upper body exercise was sufficient to induce diaphragm fatigue in a Paralympic champion adaptive rower with low-lesion spinal cord injury (SCI). An elite arms-only oarsman (age: 28 yr; stature: 1.89 m; and mass: 90.4 kg) with motor-complete SCI (T12) performed a 1,000-m time trial on an adapted rowing ergometer. Exercise measurements comprised pulmonary ventilation and gas exchange, diaphragm EMG derived indexes of neural respiratory drive, and intrathoracic pressure-derived indexes of respiratory mechanics. Diaphragm fatigue was assessed by measuring pre to postexercise changes in the twitch transdiaphragmatic pressure (Pdi,tw) response to anterolateral magnetic stimulation of the phrenic nerves. The time trial (248 +/- 25 W, 3.9 min) elicited a peak O2 uptake of 3.46 l/min and a peak pulmonary ventilation of 150 l/min (57% MVV). Breath-to-stroke ratio was 1:1 during the initial 400 m and 2:1 thereafter. The ratio of inspiratory transdiaphragmatic pressure to diaphragm EMG (neuromuscular efficiency) fell from rest to 600 m (16.0 vs. 3.0). Potentiated Pdi,tw was substantially reduced (-33%) at 15-20 min postexercise, with only partial recovery (-12%) at 30-35 min. This is the first report of exercise-induced diaphragm fatigue in SCI. The decrease in diaphragm neuromuscular efficiency during exercise suggests that the fatigue was partly due to factors independent of ventilation (e.g., posture and locomotion). NEW & NOTEWORTHY This case report provides the first objective evidence of exercise-induced diaphragm fatigue in spinal cord injury (SCI) and, for that matter, in any population undertaking upper body exercise. Our data support the notion that high levels of exercise hyperpnea and factors other than ventilation (e.g., posture and locomotion) are responsible for the fatigue noted after upper body exercise. The findings extend our understanding of the limits of physiological function in SCI. PMID- 29191983 TI - Alteration in upper airway dilator muscle coactivation during sleep: comparison of patients with obstructive sleep apnea and healthy subjects. AB - In patients with obstructive sleep apnea (OSA), substantial increases in genioglossus (GG) activity during hypopneas/apneas usually fail to restore normal airflow. We have previously suggested that sleep-induced alteration in tongue muscle coordination may explain this finding, as retractor muscle coactivation was reduced during sleep compared with wakefulness. The present study was undertaken to evaluate whether these alterations in dilator muscle activation during sleep play a role in the pathogenesis of OSA and whether coactivation of additional peripharyngeal muscles (non-GG muscles: styloglossus, geniohyoid, sternohyoid, and sternocleidomastoid) is also impaired during sleep. We compared GG and non-GG muscle electromyographic (EMG) activity in 8 patients with OSA and 12 healthy subjects during wakefulness while breathing through inspiratory resistors with the activity observed during sleep toward the end of flow limitation, before arousal, at equivalent esophageal pressures. During wakefulness, resistive breathing triggered increases in both GG and non-GG muscle activity. During sleep, flow limitation was associated with increases in GG-EMG that reached, on average, >2-fold the level observed while awake. In contrast, EMGs of the non-GG muscles, recorded simultaneously, reached, on average, only ~2/3 the wakefulness level. We conclude that during sleep GG activity may increase to levels that substantially exceed those sufficient to prevent pharyngeal collapse during wakefulness, whereas other peripharyngeal muscles do not coactivate during sleep in both patients with OSA and healthy subjects. We speculate that upper airway muscle dyssynchrony during sleep may explain why GG EMG activation fails to alleviate flow limitation and stabilize airway patency during sleep. NEW & NOTEWORTHY Pharyngeal obstruction during sleep may trigger genioglossus activity to levels substantially exceeding those observed during wakefulness, without ameliorating flow limitation. In contrast, other peripharyngeal muscles exhibit a much lower activity during sleep in both patients with obstructive sleep apnea and healthy subjects. Coordinated muscular synergy stabilizes the pharynx despite relatively low activity while awake, yet even higher genioglossal activity allows the pharynx to obstruct when simultaneous activity of other dilator muscles is inadequate during sleep.

AB - OBJECTIVE: Investigate whether hyoscine patch or glycopyrronium liquid is more effective and acceptable to treat drooling in children with neurodisability. DESIGN: Multicentre, single-blind, randomised controlled trial. SETTING: Recruitment through neurodisability teams; treatment by parents. PARTICIPANTS: Ninety children with neurodisability who had never received medication for drooling (55 boys, 35 girls; median age 4 years). EXCLUSION CRITERIA: medication contraindicated; in a trial that could affect drooling or management. INTERVENTION: Children were randomised to receive a hyoscine skin patch or glycopyrronium liquid. Dose was increased over 4 weeks to achieve optimum symptom control with minimal side-effects; steady dose then continued to 12 weeks. PRIMARY AND SECONDARY OUTCOMES: Primary outcome: Drooling Impact Scale (DIS) score at week-4. SECONDARY OUTCOMES: change in DIS scores over 12 weeks, Drooling Severity and Frequency Scale and Treatment Satisfaction Questionnaire for Medication; adverse events; children's perception about treatment. RESULTS: Both medications yielded clinically and statistically significant reductions in mean DIS at week-4 (25.0 (SD 22.2) for hyoscine and 26.6 (SD 16) for glycopyrronium). There was no significant difference in change in DIS scores between treatment groups. By week-12, 26/47 (55%) children starting treatment were receiving hyoscine compared with 31/38 (82%) on glycopyrronium. There was a 42% increased chance of being on treatment at week-12 for children randomised to glycopyrronium relative to hyoscine (1.42, 95% CI 1.04 to 1.95). CONCLUSIONS: Hyoscine and glycopyrronium are clinically effective in treating drooling in children with neurodisability. Hyoscine produced more problematic side effects leading to a greater chance of treatment cessation.

Here we report on a method termed MS Western that accurately determines the molar abundance of dozens of user-selected proteins at the subfemtomole level in whole cell or tissue lysates without metabolic or chemical labeling and without using specific antibodies. MS Western relies on GeLC-MS/MS and quantifies proteins by in-gel codigestion with an isotopically labeled QconCAT protein chimera composed of concatenated proteotypic peptides. It requires no purification of the chimera and relates the molar abundance of all proteotypic peptides to a single reference protein. In comparative experiments, MS Western outperformed immunofluorescence Western blotting by the protein detection specificity, linear dynamic range and sensitivity of protein quantification. To validate MS Western in an in vivo experiment, we quantified the molar content of zebrafish core histones H2A, H2B, H3 and H4 during ten stages of early embryogenesis. Accurate quantification (CV<10%) corroborated the anticipated histones equimolar stoichiometry and revealed an unexpected trend in their total abundance. PMID- 29192004 TI - Effectiveness of a Comprehensive Case Management Service for Children With Medical Complexity. AB - OBJECTIVES: To assess whether children with medical complexity (CMC) exposed to a hospital-based comprehensive case management service (CCMS) experience improved health care quality, improved functional status, reduced hospital-based utilization, and/or reduced overall health care costs. METHODS: Eligible CMC at Seattle Children's Hospital were enrolled in a cluster randomized controlled trial between December 1, 2010, and September 29, 2014. Participating primary care providers (PCPs) were randomly assigned, and CMC either had access to an outpatient hospital-based CCMS or usual care directed by their PCP. The CCMS included visits to a multidisciplinary clinic >= every 6 months for 1.5 years, an individualized shared care plan, and access to CCMS providers. Differences between control and intervention groups in change from baseline to 12 months and baseline to 18 months (difference of differences) were tested. RESULTS: Two hundred PCPs caring for 331 CMC were randomly assigned. Intervention group (n = 181) parents reported more improvement in the Consumer Assessment of Healthcare Providers and Systems version 4.0 Child Health Plan Survey global health care quality ratings than control group parents (6.7 [95% confidence interval (CI): 3.5-9.8] vs 1.3 [95% CI: 1.9-4.6] at 12 months). We did not detect significant differences in child functional status and most hospital-based utilization between groups. The difference in change of overall health care costs was higher in the intervention group (+$8233 [95% CI: $1701-$16 937]) at 18 months). CCMS clinic costs averaged $3847 per child-year. CONCLUSIONS: Access to a CCMS generally improved health care quality, but was not associated with changes in child functional status or hospital-based utilization, and increased overall health care costs among CMC. PMID- 29192005 TI - Successful Reversal of Furosemide-Induced Secondary Hyperparathyroidism With Cinacalcet. AB - Secondary hyperparathyroidism (SHPT) is a rare complication of furosemide therapy that can occur in patients treated with the loop diuretic for a long period of time. We report a 6-month-old 28-weeks premature infant treated chronically with furosemide for his bronchopulmonary dysplasia, who developed hypocalcemia and severe SHPT, adversely affecting his bones. Discontinuation of the loop diuretic and the addition of supplemental calcium and calcitriol only partially reversed the SHPT, bringing serum parathyroid hormone level down from 553 to 238 pg/mL. After introduction of the calcimimetic Cinacalcet, we observed a sustained normalization of parathyroid hormone concentration at 27 to 63 pg/mL and, with that correction, of all biochemical abnormalities and healing of the bone disease. No adverse effects were noted. We conclude that in cases of SHPT due to furosemide in which traditional treatment fails, there may be room to consider the addition of a calcimimetic agent.

PMID- 29192015 TI - EMA Review of Panobinostat (Farydak) for the Treatment of Adult Patients with Relapsed and/or Refractory Multiple Myeloma. AB - : On August 28, 2015, a marketing authorization valid through the European Union was issued for panobinostat, in combination with bortezomib and dexamethasone, for the treatment of adult patients with relapsed and/or refractory multiple myeloma who have received at least two prior regimens including bortezomib and an immunomodulatory agent (IMiD).Panobinostat is an orally available histone deacetylase (HDAC) inhibitor that inhibits the enzymatic activity of HDAC proteins at nanomolar concentrations. HDAC proteins catalyze the removal of acetyl groups from the lysine residues of histones and some nonhistone proteins. Inhibition of HDAC activity results in increased acetylation of histone proteins, an epigenetic alteration that results in a relaxing of chromatin, leading to transcriptional activation. The recommended starting dose of panobinostat is 20 mg, taken orally in a cyclical manner for up to 48 weeks.The use of panobinostat in combination with bortezomib and dexamethasone was studied in a randomized, double-blind, placebo-controlled, multicenter phase III study (PANORAMA I) in 768 patients with relapsed or relapsed and refractory multiple myeloma who had received one to three prior lines of therapies. In the subgroup of patients who have received at least two prior regimens including bortezomib and an IMiD, there was a difference of 7.8 months in the progression-free survival in favor of the experimental arm (12.5 months for panobinostat + bortezomib + dexamethasone vs. 4.7 months for placebo + bortezomib + dexamethasone; hazard ratio = 0.47, 95% confidence interal 0.31-0.72; log-rank p value = .0003). The incidence of grade 3 4 adverse events suspected to be related to study drug was 76.9% vs. 51.2%, for the panobinostat and the placebo group, respectively. The most common side effects (grade 3-4) associated with panobinostat included diarrhea (18.9%), fatigue (14.7%), nausea (4.5%), vomiting (5.5%), thrombocytopenia (43.6%), anemia (7.9%), neutropenia (16.5%) and lymphopenia (8.1%).This article summarizes the scientific review of the application leading to regulatory approval in the European Union. The full scientific assessment report and product information, including the Summary of Product Characteristics, are available on the European Medicines Agency website (http://www.ema.europa.eu/ema/index.jsp?curl=pages/includes/medicines/medicines_l nding_page.jsp&mid=). IMPLICATIONS FOR PRACTICE: Farydak was approved in the European Union in combination with bortezomib and dexamethasone, for the treatment of adult patients with relapsed and/or refractory multiple myeloma who have received at least two prior regimens including bortezomib and an immunomodulatory agent (IMiD). The addition of panobinostat to bortezomib and dexamethasone resulted in a clinically meaningful and statistically significant improvement of progression-free survival compared with bortezomib and dexamethasone, and an additional therapeutic option with a new mechanism of action was considered valuable. Although the toxicity associated with panobinostat combination was significant, at the time of the marketing authorization of panobinostat, it was considered that it was acceptable and that it should be left to the clinician and the patient to decide whether the panobinostat combination is the preferred treatment option or not. PMID- 29192016 TI - Comparative Efficacy of Daratumumab Monotherapy and Pomalidomide Plus Low-Dose Dexamethasone in the Treatment of Multiple Myeloma: A Matching Adjusted Indirect Comparison. AB - BACKGROUND: Daratumumab (a human CD38-directed monoclonal antibody) and pomalidomide (an immunomodulatory drug) plus dexamethasone are both relatively new treatment options for patients with heavily pretreated multiple myeloma. A matching adjusted indirect comparison (MAIC) was used to compare absolute treatment effects of daratumumab versus pomalidomide + low-dose dexamethasone (LoDex; 40 mg) on overall survival (OS), while adjusting for differences between the trial populations. MATERIALS AND METHODS: The MAIC method reduces the risk of bias associated with naive indirect comparisons. Data from 148 patients receiving daratumumab (16 mg/kg), pooled from the GEN501 and SIRIUS studies, were compared separately with data from patients receiving pomalidomide + LoDex in the MM-003 and STRATUS studies. RESULTS: The MAIC-adjusted hazard ratio (HR) for OS of daratumumab versus pomalidomide + LoDex was 0.56 (95% confidence interval [CI], 0.38-0.83; p = .0041) for MM-003 and 0.51 (95% CI, 0.37-0.69; p < .0001) for STRATUS. The treatment benefit was even more pronounced when the daratumumab population was restricted to pomalidomide-naive patients (MM-003: HR, 0.33; 95% CI, 0.17-0.66; p = .0017; STRATUS: HR, 0.41; 95% CI, 0.21-0.79; p = .0082). An additional analysis indicated a consistent trend of the OS benefit across subgroups based on M-protein level reduction (>=50%, >=25%, and <25%). CONCLUSION: The MAIC results suggest that daratumumab improves OS compared with pomalidomide + LoDex in patients with heavily pretreated multiple myeloma. IMPLICATIONS FOR PRACTICE: This matching adjusted indirect comparison of clinical trial data from four studies analyzes the survival outcomes of patients with heavily pretreated, relapsed/refractory multiple myeloma who received either daratumumab monotherapy or pomalidomide plus low-dose dexamethasone. Using this method, daratumumab conferred a significant overall survival benefit compared with pomalidomide plus low-dose dexamethasone. In the absence of head-to-head trials, these indirect comparisons provide useful insights to clinicians and reimbursement authorities around the relative efficacy of treatments.

AB - BACKGROUND: The management of localized extremity soft tissue sarcomas (STS) is challenging and the role of pre- and postoperative chemotherapy is unclear and debated among experts. MATERIALS AND METHODS: Medical oncology experts of the European Organization for Research and Treatment of Cancer Soft Tissue and Bone Sarcoma Group were asked to participate in this survey on the use of pre- and postoperative chemotherapy in STS. Experts from 12 centers in Belgium, France, Germany, Great Britain, Italy, Switzerland, and The Netherlands agreed to participate and provided their treatment algorithm. Answers were converted into decision trees based on the objective consensus methodology. The decision trees were used as a basis to identify consensus and discrepancies. RESULTS: Several criteria used for decision-making in extremity STS were identified: chemosensitivity, fitness, grading, location, and size. In addition, resectability and resection status were relevant in the pre- and postoperative setting, respectively. Preoperative chemotherapy is considered in most centers for marginally resectable tumors only. Yet, in some centers, neoadjuvant chemotherapy is used routinely and partially combined with hyperthermia. Although most centers do not recommend postoperative chemotherapy, some offer this treatment on a regular basis. Radiotherapy is an undisputed treatment modality in extremity STS. CONCLUSION: Due to lacking evidence on the utility of pre- and postoperative chemotherapy in localized extremity STS, treatment strategies vary considerably among European experts. The majority recommended neoadjuvant chemotherapy for marginally resectable grade 2-3 tumors; the majority did not recommend postoperative chemotherapy in any setting. IMPLICATIONS FOR PRACTICE: The management of localized extremity soft tissue sarcomas (STS) is challenging and the role of pre- and postoperative chemotherapy is unclear and debated among experts. This study analyzed the decision-making process among 12 European experts on systemic therapy for STS. A wide range of recommendations among experts regarding the use of perioperative chemotherapy was discovered. Discrepancies in the use of decision criteria were also uncovered, including the definition of what constitutes high-risk cancer, which is a basis for many to recommend chemotherapy. Before any standardization is possible, a common use of decision criteria is necessary. PMID- 29192020 TI - Sexual health services on the brink.

AB - Neuropsychological and neurophysiological studies have emphasized the role of the prefrontal cortex (PFC) in maintaining information about the temporal order of events or items for upcoming actions. However, the medial temporal lobe (MTL) has also been considered critical to bind individual events or items to their temporal context in episodic memory. Here we characterize the contributions of these brain areas by comparing single-unit activity in the dorsal and ventral regions of macaque lateral PFC (d-PFC and v-PFC) with activity in MTL areas including the hippocampus (HPC), entorhinal cortex, and perirhinal cortex (PRC) as well as in area TE during the encoding phase of a temporal-order memory task. The v-PFC cells signaled specific items at particular time periods of the task. By contrast, MTL cortical cells signaled specific items across multiple time periods and discriminated the items between time periods by modulating their firing rates. Analysis of the temporal dynamics of these signals showed that the conjunctive signal of item and temporal-order information in PRC developed earlier than that seen in v-PFC. During the delay interval between the two cue stimuli, while v-PFC provided prominent stimulus-selective delay activity, MTL areas did not. Both regions of PFC and HPC exhibited an incremental timing signal that appeared to represent the continuous passage of time during the encoding phase. However, the incremental timing signal in HPC was more prominent than that observed in PFC. These results suggest that PFC and MTL contribute to the encoding of the integration of item and timing information in distinct ways. PMID- 29192023 TI - Galphas protein binds ubiquitin to regulate epidermal growth factor receptor endosomal sorting. AB - The Galphas subunit is classically involved in the signal transduction of G protein-coupled receptors (GPCRs) at the plasma membrane. Recent evidence has revealed noncanonical roles for Galphas in endosomal sorting of receptors to lysosomes. However, the mechanism of action of Galphas in this sorting step is still poorly characterized. Here, we report that Galphas interacts with ubiquitin to regulate the endosomal sorting of receptors for lysosomal degradation. We reveal that the N-terminal extremity of Galphas contains a ubiquitin-interacting motif (UIM), a sorting element usually found in the endosomal sorting complex required for transport (ESCRT) machinery responsible for sorting ubiquitinated receptors into intraluminal vesicles (ILVs) of multivesicular bodies (MVBs). Mutation of the UIM in Galphas confirmed the importance of ubiquitin interaction for the sorting of epidermal growth factor receptor (EGFR) into ILVs for lysosomal degradation. These findings demonstrate a role for Galphas as an integral component of the ubiquitin-dependent endosomal sorting machinery and highlight the dual role of Galphas in receptor trafficking and signaling for the fine-tuning of the cellular response. PMID- 29192024 TI - Eph-ephrin signaling modulated by polymerization and condensation of receptors. AB - Eph receptor signaling plays key roles in vertebrate tissue boundary formation, axonal pathfinding, and stem cell regeneration by steering cells to positions defined by its ligand ephrin. Some of the key events in Eph-ephrin signaling are understood: ephrin binding triggers the clustering of the Eph receptor, fostering transphosphorylation and signal transduction into the cell. However, a quantitative and mechanistic understanding of how the signal is processed by the recipient cell into precise and proportional responses is largely lacking. Studying Eph activation kinetics requires spatiotemporal data on the number and distribution of receptor oligomers, which is beyond the quantitative power offered by prevalent imaging methods. Here we describe an enhanced fluorescence fluctuation imaging analysis, which employs statistical resampling to measure the Eph receptor aggregation distribution within each pixel of an image. By performing this analysis over time courses extending tens of minutes, the information-rich 4D space (x, y, oligomerization, time) results were coupled to straightforward biophysical models of protein aggregation. This analysis reveals that Eph clustering can be explained by the combined contribution of polymerization of receptors into clusters, followed by their condensation into far larger aggregates. The modeling reveals that these two competing oligomerization mechanisms play distinct roles: polymerization mediates the activation of the receptor by assembling monomers into 6- to 8-mer oligomers; condensation of the preassembled oligomers into large clusters containing hundreds of monomers dampens the signaling. We propose that the polymerization condensation dynamics creates mechanistic explanation for how cells properly respond to variable ligand concentrations and gradients. PMID- 29192025 TI - STOREKEEPER RELATED1/G-Element Binding Protein (STKR1) Interacts with Protein Kinase SnRK1. AB - Sucrose nonfermenting related kinase1 (SnRK1) is a conserved energy sensor kinase that regulates cellular adaptation to energy deficit in plants. Activation of SnRK1 leads to the down-regulation of ATP-consuming biosynthetic processes and the stimulation of energy-generating catabolic reactions by transcriptional reprogramming and posttranslational modifications. Although considerable progress has been made during the last years in understanding the SnRK1 signaling pathway, many of its components remain unidentified. Here, we show that the catalytic alpha-subunits KIN10 and KIN11 of the Arabidopsis (Arabidopsis thaliana) SnRK1 complex interact with the STOREKEEPER RELATED1/G-Element Binding Protein (STKR1) inside the plant cell nucleus. Overexpression of STKR1 in transgenic Arabidopsis plants led to reduced growth, a delay in flowering, and strongly attenuated senescence. Metabolite profiling revealed that the transgenic lines exhausted their carbohydrates during the dark period to a greater extent than the wild type and accumulated a range of amino acids. At the global transcriptome level, genes affected by STKR1 overexpression were broadly associated with systemic acquired resistance, and transgenic plants showed enhanced resistance toward a virulent strain of the biotrophic oomycete pathogen Hyaloperonospora arabidopsidis Noco2. We discuss a possible connection of STKR1 function, SnRK1 signaling, and plant immunity. PMID- 29192026 TI - Reassessing the Roles of PIN Proteins and Anticlinal Microtubules during Pavement Cell Morphogenesis. AB - The leaf epidermis is a biomechanical shell that influences the size and shape of the organ. Its morphogenesis is a multiscale process in which nanometer-scale cytoskeletal protein complexes, individual cells, and groups of cells pattern growth and define macroscopic leaf traits. Interdigitated growth of neighboring cells is an evolutionarily conserved developmental strategy. Understanding how signaling pathways and cytoskeletal proteins pattern cell walls during this form of tissue morphogenesis is an important research challenge. The cellular and molecular control of a lobed cell morphology is currently thought to involve PIN FORMED (PIN)-type plasma membrane efflux carriers that generate subcellular auxin gradients. Auxin gradients were proposed to function across cell boundaries to encode stable offset patterns of cortical microtubules and actin filaments between adjacent cells. Many models suggest that long-lived microtubules along the anticlinal cell wall generate local cell wall heterogeneities that restrict local growth and specify the timing and location of lobe formation. Here, we used Arabidopsis (Arabidopsis thaliana) reverse genetics and multivariate long-term time-lapse imaging to test current cell shape control models. We found that neither PIN proteins nor long-lived microtubules along the anticlinal wall predict the patterns of lobe formation. In fields of lobing cells, anticlinal microtubules are not correlated with cell shape and are unstable at the time scales of cell expansion. Our analyses indicate that anticlinal microtubules have multiple functions in pavement cells and that lobe initiation is likely controlled by complex interactions among cell geometry, cell wall stress patterns, and transient microtubule networks that span the anticlinal and periclinal walls. PMID- 29192027 TI - Transcription Factor-Mediated Control of Anthocyanin Biosynthesis in Vegetative Tissues. AB - Plants accumulate secondary metabolites to adapt to environmental conditions. These compounds, here exemplified by the purple-colored anthocyanins, are accumulated upon high temperatures, UV-light, drought, and nutrient deficiencies, and may contribute to tolerance to these stresses. Producing compounds is often part of a more broad response of the plant to changes in the environment. Here we investigate how a transcription-factor-mediated program for controlling anthocyanin biosynthesis also has effects on formation of specialized cell structures and changes in the plant root architecture. A systems biology approach was developed in tomato (Solanum lycopersicum) for coordinated induction of biosynthesis of anthocyanins, in a tissue- and development-independent manner. A transcription factor couple from Antirrhinum that is known to control anthocyanin biosynthesis was introduced in tomato under control of a dexamethasone-inducible promoter. By application of dexamethasone, anthocyanin formation was induced within 24 h in vegetative tissues and in undifferentiated cells. Profiles of metabolites and gene expression were analyzed in several tomato tissues. Changes in concentration of anthocyanins and other phenolic compounds were observed in all tested tissues, accompanied by induction of the biosynthetic pathways leading from Glc to anthocyanins. A number of pathways that are not known to be involved in anthocyanin biosynthesis were observed to be regulated. Anthocyanin-producing plants displayed profound physiological and architectural changes, depending on the tissue, including root branching, root epithelial cell morphology, seed germination, and leaf conductance. The inducible anthocyanin-production system reveals a range of phenomena that accompanies anthocyanin biosynthesis in tomato, including adaptions of the plants architecture and physiology. PMID- 29192028 TI - The Impacts of Fluctuating Light on Crop Performance. AB - Rapidly changing light conditions can reduce carbon gain and productivity in field crops because photosynthetic responses to light fluctuations are not instantaneous. Plant responses to fluctuating light occur across levels of organizational complexity from entire canopies to the biochemistry of a single reaction and across orders of magnitude of time. Although light availability and variation at the top of the canopy are largely dependent on the solar angle and degree of cloudiness, lower crop canopies rely more heavily on light in the form of sunflecks, the quantity of which depends mostly on canopy structure but also may be affected by wind. The ability of leaf photosynthesis to respond rapidly to these variations in light intensity is restricted by the relatively slow opening/closing of stomata, activation/deactivation of C3 cycle enzymes, and up regulation/down-regulation of photoprotective processes. The metabolic complexity of C4 photosynthesis creates the apparently contradictory possibilities that C4 photosynthesis may be both more and less resilient than C3 to dynamic light regimes, depending on the frequency at which these light fluctuations occur. We review the current understanding of the underlying mechanisms of these limitations to photosynthesis in fluctuating light that have shown promise in improving the response times of photosynthesis-related processes to changes in light intensity.

PMID- 29192060 TI - High-content tripartite split-GFP cell-based assays to screen for modulators of small GTPase activation. AB - The human Ras superfamily of small GTPases controls essential cellular processes such as gene expression and cell proliferation. As their deregulation is widely associated with human cancer, small GTPases and their regulatory proteins have become increasingly attractive for the development of novel therapeutics. Classical methods to monitor GTPase activation include pulldown assays that limit the analysis of GTP-bound form of proteins from cell lysates. Alternatively, live cell FRET biosensors may be used to study GTPase activation dynamics in response to stimuli, but these sensors often require further optimization for high throughput applications. Here, we describe a cell-based approach that is suitable to monitor the modulation of small GTPase activity in a high-content analysis. The assay relies on a genetically encoded tripartite split-GFP (triSFP) system that we integrated in an optimized cellular model to monitor modulation of RhoA and RhoB GTPases. Our results indicate the robust response of the reporter, allowing the interrogation of inhibition and stimulation of Rho activity, and highlight potential applications of this method to discover novel modulators and regulators of small GTPases and related protein-binding domains. PMID- 29192062 TI - Distinct roles for plasma membrane PtdIns(4)P and PtdIns(4,5)P2 during receptor mediated endocytosis in yeast. AB - Clathrin-mediated endocytosis requires the coordinated assembly of various endocytic proteins and lipids at the plasma membrane. Accumulating evidence demonstrates a crucial role for phosphatidylinositol-4,5-bisphosphate [PtdIns(4,5)P2] in endocytosis but specific roles for phosphatidylinositol-4 phosphate [PtdIns(4)P], other than as the biosynthetic precursor of PtdIns(4,5)P2, have not been clarified. In this study we investigated the roles of PtdIns(4)P and PtdIns(4,5)P2 in receptor-mediated endocytosis through the construction of temperature-sensitive (ts) mutants for the phosphatidylinositol 4 kinases (PI4-kinases) Stt4p and Pik1p and the 1-phosphatidylinositol-4-phosphate 5-kinase [PtdIns(4) 5-kinase] Mss4p. Quantitative analyses of endocytosis revealed that both the stt4tspik1ts and mss4ts mutants have a severe defect in endocytic internalization. Live-cell imaging of endocytic protein dynamics in stt4tspik1ts and mss4ts mutants revealed that PtdIns(4)P is required for the recruitment of the alpha-factor receptor Ste2p to clathrin-coated pits, whereas PtdIns(4,5)P2 is required for membrane internalization. We also found that the localization to endocytic sites of the ENTH/ANTH domain-bearing clathrin adaptors, Ent1p, Ent2p, Yap1801p and Yap1802p, is significantly impaired in the stt4tspik1ts mutant but not in the mss4ts mutant. These results suggest distinct roles in successive steps for PtdIns(4)P and PtdIns(4,5)P2 during receptor mediated endocytosis. PMID- 29192061 TI - NudE regulates dynein at kinetochores but is dispensable for other dynein functions in the C. elegans early embryo. AB - In mitosis, the molecular motor dynein is recruited to kinetochores by the Rod Zw10-Zwilch complex (RZZ) and Spindly to control spindle assembly checkpoint (SAC) signaling and microtubule attachment. How the ubiquitous dynein co-factors Lis1 and NudE contribute to these functions remains poorly understood. Here, we show that the C. elegans NudE homolog NUD-2 is dispensable for dynein- and LIS-1 dependent mitotic spindle assembly in the zygote. This facilitates functional characterization of kinetochore-localized NUD-2, which is recruited by the CENP-F like proteins HCP-1 and HCP-2 independently of RZZ-Spindly and dynein-LIS-1. Kinetochore dynein levels are reduced in Deltanud-2 embryos, and, as occurs upon RZZ inhibition, loss of NUD-2 delays the formation of load-bearing kinetochore microtubule attachments and causes chromatin bridges in anaphase. Survival of Deltanud-2 embryos requires a functional SAC, and kinetochores without NUD-2 recruit an excess of SAC proteins. Consistent with this, SAC signaling in early Deltanud-2 embryos extends mitotic duration and prevents high rates of chromosome mis-segregation. Our results reveal that both NUD-2 and RZZ-Spindly are essential for dynein function at kinetochores, and that the gain in SAC strength during early embryonic development is relevant under conditions that mildly perturb mitosis. PMID- 29192063 TI - Mechanism of inhibition of taurolithocholate-induced retrieval of plasma membrane MRP2 by cyclic AMP and tauroursodeoxycholate. AB - Taurolithocholate (TLC) produces cholestasis by inhibiting biliary solute secretion in part by retrieving MRP2 from the plasma membrane (PM). Tauroursodeoxycholate (TUDC) and cAMP reverse TLC-induced cholestasis by inhibiting TLC-induced retrieval of MRP2. However, cellular mechanisms for this reversal are incompletely understood. Recently, we reported that TLC decreases PM MRP2 by activating PKCepsilon followed by phosphorylation of myristoylated alanine-rich C kinase substrate (MARCKS). Thus, cAMP and TUDC may reverse TLC induced cholestasis by inhibiting the TLC/PKCepsilon/MARCKS phosphorylation pathway. We tested this hypothesis by determining whether TUDC and/or cAMP inhibit TLC-induced activation of PKCepsilon and phosphorylation of MARCKS Studies were conducted in HuH-NTCP cell line and rat hepatocytes. Activation of PKCepsilon was determined from the translocation of PKCepsilon to PM using a biotinylation method. Phosphorylation of MARCKS was determined by immunoblotting with a phospho-MARCKS antibody. TLC, but not cAMP and TUDC, activated PKCepsilon and increased MARCKS phosphorylation in HuH-NTCP as well in rat hepatocytes. Treatment with TUDC or cAMP inhibited TLC-induced activation of PKCepsilon and increases in MARCKS phosphorylation in both cell types. Based on these results, we conclude that the reversal of TLC-induced cholestasis by cAMP and TUDC involves, at least in part, inhibition of TLC-mediated activation of the PKCepsilon/MARCKS phosphorylation pathway.

AB - The renal podocyte is central to the filtration function of the kidney that is dependent on maintaining both highly organized, branched cell structures forming foot processes, and a unique cell-cell junction, the slit diaphragm. Our recent studies investigating the developmental formation of the slit diaphragm identified a novel claudin family tetraspannin, TM4SF10, which is a binding partner for ADAP (also known as Fyn binding protein Fyb). To investigate the role of ADAP in podocyte function in relation to Fyn and TM4SF10, we examined ADAP knockout (KO) mice and podocytes. ADAP KO mice developed glomerular pathology that began as hyalinosis and progressed to glomerulosclerosis, with aged male animals developing low levels of albuminuria. Podocyte cell lines established from the KO mice had slower attachment kinetics compared to wild-type cells, although this did not affect the total number of attached cells nor the ability to form focal contacts. After attachment, the ADAP KO cells did not attain typical podocyte morphology, lacking the elaborate cell protrusions typical of wild-type podocytes, with the actin cytoskeleton forming circumferential stress fibers. The absence of ADAP did not alter Fyn levels nor were there differences between KO and wild-type podocytes in the reduction of Fyn activating phosphorylation events with puromycin aminonucleoside treatment. In the setting of endogenous TM4SF10 overexpression, the absence of ADAP altered the formation of cell-cell contacts containing TM4SF10. These studies suggest ADAP does not alter Fyn activity in podocytes, but appears to mediate downstream effects of Fyn controlled by TM4SF10 involving actin cytoskeleton organization.

AB - Nerve function assessments are crucial for surgical intervention during acoustic neuroma surgery. Cranial nerves such as acoustic and facial nerves, can be possibly damaged during tumor dissection. Proper surgical intervention should prevent neurological deficit and achieve total tumor removal. Conventionally, nerve function is qualitatively evaluated by surgeon and neurologist. Facial nerves can be preserved by monitoring the compound muscle action potential (CMAP) response. The differences in the amplitude and latency of CMAP are used as indicators during surgical interventions. However, baseline CMAPs cannot be recorded in the presence of large acoustic tumors. This paper presents a new way of estimating nerve function. Instead of a single CMAP examination, multi-CMAP responses are obtained from a train of varied stimulus intensities and these are applied a mathematical model. Shifts in the mathematical model parameters reflect changes in facial nerve function. In this study, experiments conducted in frog revealed that shifts in the linear model parameters were related to the level of induced nerve injury. Significant differences in the slope parameter of the linear model were found between each nerve condition. The identification of healthy and severed nerves via a support vector machine (SVM) corresponded to 94% accuracy. This classification criterion could be used with surgical intervention to prevent severed facial nerve palsy in acoustic neuroma surgery. The proposed method could be used to estimate nerve outcomes without prior information of a CMAP baseline.

However, whether other cytokines are secreted is currently unknown. Skeletal muscle ex vivo preparations commonly used to study cytokine secretion have dealt with limitations including auto-oxidation of catecholamines. The use of metal chelators could be an alternative to avoid auto-oxidation and allow catecholamines to be used at physiological doses. We exposed isolated soleus muscles to 1 or 100 ng/mL epinephrine (EPI) and collected bath samples at 1 and 2 h for multiplex cytokine analysis. Keratinocyte chemoattractant (CXCL1), IL-6, and IL-1alpha were significantly elevated by 100 ng/mL exposure, but not by 1 ng/mL (median [CXCL1] (2 h) = 83 pg/mL; [IL-6] = 19 pg/mL; IL-1alpha = 7.5 pg/mL). CXCL1 and IL-6 were highly correlated in each sample (P = 0.0001). A second experiment combined the metal chelator, deferoxamine mesylate (DFO), to prevent EPI autoxidation, with 2 ng/mL EPI and 10.5 ng/mL norepinephrine (NOREPI) to mimic peak exercise. Unexpectedly, DFO alone stimulated both IL-6 and CXCL1 secretion, but together with EPI and NOREPI had no additional effects. Stimulation of cytokine secretory responses from skeletal muscle cells in response to DFO thus precludes its use as a chelating agent in ex vivo models. In conclusion, 100 ng/mL EPI stimulates a robust secretory CXCL1 response, which together with IL-6 and IL-1alpha, may constitute an adrenal-muscle endocrine response system. PMID- 29192068 TI - Passive elongation of muscle fascicles in human muscles with short and long tendons. AB - This study tested the hypothesis that the ratio of changes in muscle fascicle and tendon length that occurs with joint movement scales linearly with the ratio of the slack lengths of the muscle fascicles and tendons. We compared the contribution of muscle fascicles to passive muscle-tendon lengthening in muscles with relatively short and long fascicles. Fifteen healthy adults participated in the study. The medial gastrocnemius, tibialis anterior, and brachialis muscle tendon units were passively lengthened by slowly rotating the ankle or elbow. Change in muscle fascicle length was measured with ultrasonography. Change in muscle-tendon length was calculated from estimated muscle moment arms. Change in tendon length was calculated by subtracting change in fascicle length from change in muscle-tendon length. The median (IQR) contribution of muscle fascicles to passive lengthening of the muscle-tendon unit, measured as the ratio of the change in fascicle length to the change in muscle-tendon unit length, was 0.39 (0.26-0.48) for the medial gastrocnemius, 0.51 (0.29-0.60) for tibialis anterior, and 0.65 (0.49-0.90) for brachialis. Brachialis muscle fascicles contributed to muscle-tendon unit lengthening significantly more than medial gastrocnemius muscle fascicles, but less than would be expected if the fascicle contribution scaled linearly with the ratio of muscle fascicle and tendon slack lengths. PMID- 29192067 TI - Effect of myostatin deletion on cardiac and microvascular function. AB - The objective of this study is to test the hypothesis that increased muscle mass has positive effects on cardiovascular function. Specifically, we tested the hypothesis that increases in lean body mass caused by deletion of myostatin improves cardiac performance and vascular function. Echocardiography was used to quantify left ventricular function at baseline and after acute administration of propranolol and isoproterenol to assess beta-adrenergic reactivity. Additionally, resistance vessels in several beds were removed, cannulated, pressurized to 60 mmHg and reactivity to vasoactive stimuli was assessed. Hemodynamics were measured using in vivo radiotelemetry. Myostatin deletion results in increased fractional shortening at baseline. Additionally, arterioles in the coronary and muscular microcirculations are more sensitive to endothelial-dependent dilation while nonmuscular beds or the aorta were unaffected. beta-adrenergic dilation was increased in both coronary and conduit arteries, suggesting a systemic effect of increased muscle mass on vascular function. Overall hemodynamics and physical characteristics (heart weight and size) remained unchanged. Myostatin deletion mimics in part the effects of exercise on cardiovascular function. It significantly increases lean muscle mass and results in muscle-specific increases in endothelium-dependent vasodilation. This suggests that increases in muscle mass may serve as a buffer against pathological states that specifically target cardiac function (heart failure), the beta-adrenergic system (age), and nitric oxide bio-availability (atherosclerosis). Taken together, pharmacological inhibition of the myostatin pathway could prove an excellent mechanism by which the benefits of exercise can be conferred in patients that are unable to exercise.

AB - BACKGROUND: Recreational marijuana has been legalized in 11 jurisdictions; Canada will legalize marijuana by July 2018. With this changing landscape, there is a need to understand the public health risks associated with marijuana to support patient-care provider conversations, harm-reduction measures and evidence informed policy. The objective of this work was to summarize the health effects of exposure to second- and third-hand marijuana smoke. METHODS: In this systematic review, we searched 6 databases from inception to October 2017. Abstract and full-text review was conducted in duplicate. Studies were included if they were human, in vivo or in vitro studies with more than 1 case reported in English or French, and reported original, quantitative data. Three outcomes were extracted: 1) cannabinoids and cannabinoid metabolites in bodily fluids, 2) self reported psychoactive effects and 3) eye irritation and discomfort. RESULTS: Of the 1701 abstracts identified, 60 proceeded to full-text review; the final data set contained 15 articles. All of the included studies were of good to poor quality as assessed with the Downs and Black checklist. There is evidence of a direct relation between the tetrahydrocannabinol content of marijuana and effects on those passively exposed. This relation is mediated by several environmental factors including the amount of smoke, ventilation, air volume, number of marijuana cigarettes lit and number of smokers present. No evidence was identified assessing exposure to third-hand marijuana smoke or the health effects of long-term exposure. INTERPRETATION: Exposure to second-hand marijuana smoke leads to cannabinoid metabolites in bodily fluids, and people experience psychoactive effects after such exposure. Alignment of tobacco and marijuana smoking bylaws may result in the most effective public policies. More research is required to understand the impact of exposure to third-hand smoke and the health effects of long-term exposure to second-hand smoke. PMID- 29192094 TI - Overproduction of growth differentiation factor 15 promotes human rhinovirus infection and virus-induced inflammation in the lung. AB - Human rhinovirus (HRV) is the most common virus contributing to acute exacerbations of chronic obstructive pulmonary disease (COPD) nearly year round, but the mechanisms have not been well elucidated. Recent clinical studies suggest that high levels of growth differentiation factor 15 (GDF15) protein in the blood are associated with an increased yearly rate of all-cause COPD exacerbations. Therefore, in the current study, we investigated whether GDF15 promotes HRV infection and virus-induced lung inflammation. We first examined the role of GDF15 in regulating host defense and HRV-induced inflammation using human GDF15 transgenic mice and cultured human GDF15 transgenic mouse tracheal epithelial cells. Next, we determined the effect of GDF15 on viral replication, antiviral responses, and inflammation in human airway epithelial cells with GDF15 knockdown and HRV infection. Finally, we explored the signaling pathways involved in airway epithelial responses to HRV infection in the context of GDF15. Human GDF15 protein overexpression in mice led to exaggerated inflammatory responses to HRV, increased infectious particle release, and decreased IFN-lambda2/3 (IL-28A/B) mRNA expression in the lung. Moreover, GDF15 facilitated HRV replication and inflammation via inhibiting IFN-lambda1/IL-29 protein production in human airway epithelial cells. Lastly, Smad1 cooperated with interferon regulatory factor 7 (IRF7) to regulate airway epithelial responses to HRV infection partly via GDF15 signaling. Our results reveal a novel function of GDF15 in promoting lung HRV infection and virus-induced inflammation, which may be a new mechanism for the increased susceptibility and severity of respiratory viral (i.e., HRV) infection in cigarette smoke-exposed airways with GDF15 overproduction.

PMID- 29192122 TI - Propofol Is an Allosteric Agonist with Multiple Binding Sites on Concatemeric Ternary GABAA Receptors. AB - GABAA receptors can be directly activated and potentiated by the intravenous anesthetic propofol. Previous photolabeling, modeling, and functional data have identified two binding domains through which propofol acts on the GABAA receptor. These domains are defined by the beta(M286) residue at the beta"+"-alpha"-" interface in the transmembrane region and the beta(Y143) residue near the beta"-" surface in the junction between the extracellular and transmembrane domains. In the ternary receptor, there are predicted to be two copies of each class of sites, for a total of four sites per receptor. We used beta2alpha1gamma2L and beta2alpha1 concatemeric constructs to determine the functional effects of the beta(Y143W) and beta(M286W) mutations to gain insight into the number of functional binding sites for propofol and the energetic contributions stemming from propofol binding to the individual sites. A mutation of each of the four sites affected the response to propofol, indicating that each of the four sites is functional in the wild-type receptor. The mutations mainly impaired stabilization of the open state by propofol, i.e., reduced gating efficacy. The effects were similar for mutations at either site and were largely additive and independent of the presence of other Y143W or M286W mutations in the receptor. The two classes of sites appeared to differ in affinity for propofol, with the site affected by M286W having about a 2-fold higher affinity. Our analysis indicates there may be one or two additional functionally equivalent binding sites for propofol, other than those modified by substitutions at beta(Y143) and beta(M286).

AB - The CB2 cannabinoid agonist LY2828360 lacked both toxicity and efficacy in a clinical trial for osteoarthritis. Whether LY2828360 suppresses neuropathic pain has not been reported, and its signaling profile is unknown. In vitro, LY2828360 was a slowly acting but efficacious G protein-biased CB2 agonist, inhibiting cAMP accumulation and activating extracellular signal-regulated kinase 1/2 signaling while failing to recruit arrestin, activate inositol phosphate signaling, or internalize CB2 receptors. In wild-type (WT) mice, LY2828360 (3 mg/kg per day i.p. * 12 days) suppressed chemotherapy-induced neuropathic pain produced by paclitaxel without producing tolerance. Antiallodynic efficacy of LY2828360 was absent in CB2 knockout (KO) mice. Morphine (10 mg/kg per day i.p. * 12 days) tolerance developed in CB2KO mice but not in WT mice with a history of LY2828360 treatment (3 mg/kg per day i.p. * 12 days). LY2828360-induced antiallodynic efficacy was preserved in WT mice previously rendered tolerant to morphine (10 mg/kg per day i.p. * 12 days), but it was absent in morphine-tolerant CB2KO mice. Coadministration of LY2828360 (0.1 mg/kg per day i.p. * 12 days) with morphine (10 mg/kg per day * 12 days) blocked morphine tolerance in WT but not in CB2KO mice. WT mice that received LY2828360 coadministered with morphine exhibited a trend (P = 0.055) toward fewer naloxone-precipitated jumps compared with CB2KO mice. In conclusion, LY2828360 is a slowly signaling, G protein-biased CB2 agonist that attenuates chemotherapy-induced neuropathic pain without producing tolerance and may prolong effective opioid analgesia while reducing opioid dependence. LY2828360 may be useful as a first-line treatment in chemotherapy induced neuropathic pain and may be highly efficacious in neuropathic pain states that are refractive to opioid analgesics. PMID- 29192124 TI - Drugs and Scaffold That Inhibit Cytochrome P450 27A1 In Vitro and In Vivo. AB - Cytochrome P450 27A1 (CYP27A1) is a ubiquitous enzyme that hydroxylates cholesterol and other sterols. Complete CYP27A1 deficiency owing to genetic mutations is detrimental to human health, whereas 50% of activity retention is not and does not affect the whole body cholesterol levels. CYP27A1 is considered a potential therapeutic target in breast cancer and age-related neurodegenerative diseases; however, CYP27A1 inhibition should be <=50%. Herein, 131 pharmaceuticals were tested for their effect on CYP27A1-mediated cholesterol 27 hydroxylation by in vitro enzyme assay. Of them, 14 drugs inhibited CYP27A1 by >=75% and were evaluated for in vitro binding to the enzyme active site and for inhibition constants. All drugs except one (dasatinib) elicited a spectral response in CYP27A1 and had Ki values for cholesterol 27-hydroxylation either in the submicromolar (clevidipine, delavirdine, etravirine, felodipine, nicardipine, nilotinib, and sorafenib) or low micromolar range (abiratone, candesartan, celecoxib, dasatinib, nilvadipine, nimodipine, and regorafenib). Clevidipine, felodipine, nicardipine, nilvadipine, and nimodipine have the same 1,4 dihydropyridine scaffold and are indicated for hypertension. We used two of these antihypertensives (felodipine and nilvadipine) for administration to mice at a 1 mg/kg of body weight dose, daily, for 7 days. Mouse 27-hydroxycholesterol levels in the plasma, brain, and liver were reduced, whereas tissue levels of total cholesterol were unchanged. Structure-activity relationships within the 1,4 dihydropyridine scaffold were investigated, and features important for CY27A1 inhibition were identified. We confirmed our previous finding that CYP27A1 is a druggable enzyme and found additional drugs as well as the scaffold with potential for partial CYP27A1 inhibition in humans.

Before a motor phenotype, animal models of HD show aberrant cortical-striatal glutamate signaling. Here, we tested synaptic plasticity of cortical excitatory synapses onto striatal spiny projection neurons (SPNs) early in the YAC128 mouse model of HD. High-frequency stimulation-induced long-term depression, mediated by the endocannabinoid anandamide and cannabinoid receptor 1 (CB1), was significantly attenuated in male and female YAC128 SPNs. Indirect pathway SPNs, which are more vulnerable in HD, were most affected. Our experiments show metabotropic glutamate receptor and endocannabinoid 2-arachidonoylglycerol dependent plasticity, as well as direct CB1 activation by agonists, was similar in YAC128 and FVB/N wild-type SPNs suggesting that presynaptic CB1 is functioning normally. These results are consistent with a specific impairment in postsynaptic anandamide synthesis in YAC128 SPN. Strikingly, although suppression of degradation of anandamide was not effective, elevating 2-arachidonoylglycerol levels restored long-term depression in YAC128 striatal neurons. Together, these results have potential implications for neuroprotection and ameliorating early cognitive and motor deficits in HD.SIGNIFICANCE STATEMENT Huntington's disease (HD) is an inherited neurodegenerative disease with no cure. Recent studies find impairment of the endocannabinoid system in animal models but the functional implication for synaptic plasticity in HD remains unclear. Sepers et al. show a selective deficit in synaptic plasticity mediated by the endocannabinoid anandamide, but not 2-arachidonoylglycerol in a mouse model of HD. The deficit is rescued by selectively elevating levels of 2-arachidonoylglycerol produced on demand. This mechanism could be targeted in the development of future therapeutics for HD. PMID- 29192126 TI - Entorhinal Tau Pathology, Episodic Memory Decline, and Neurodegeneration in Aging. AB - The medial temporal lobe (MTL) is an early site of tau accumulation and MTL dysfunction may underlie episodic-memory decline in aging and dementia. Postmortem data indicate that tau pathology in the transentorhinal cortex is common by age 60, whereas spread to neocortical regions and worsening of cognition is associated with beta-amyloid (Abeta). We used [18F]AV-1451 and [11C]PiB positron emission tomography, structural MRI, and neuropsychological assessment to investigate how in vivo tau accumulation in temporal lobe regions, Abeta, and MTL atrophy contribute to episodic memory in cognitively normal older adults (n = 83; age, 77 +/- 6 years; 58% female). Stepwise regressions identified tau in MTL regions known to be affected in old age as the best predictor of episodic-memory performance independent of Abeta status. There was no interactive effect of MTL tau with Abeta on memory. Higher MTL tau was related to higher age in the subjects without evidence of Abeta. Among temporal lobe subregions, episodic memory was most strongly related to tau-tracer uptake in the parahippocampal gyrus, particularly the posterior entorhinal cortex, which in our parcellation includes the transentorhinal cortex. In subjects with longitudinal MRI and cognitive data (n = 57), entorhinal atrophy mirrored patterns of tau pathology and their relationship with memory decline. Our data are consistent with neuropathological studies and further suggest that entorhinal tau pathology underlies memory decline in old age even without Abeta.SIGNIFICANCE STATEMENT Tau tangles and beta-amyloid (Abeta) plaques are key lesions in Alzheimer's disease (AD) but both pathologies also occur in cognitively normal older people. Neuropathological data indicate that tau tangles in the medial temporal lobe (MTL) underlie episodic-memory impairments in AD dementia. However, it remains unclear whether MTL tau pathology also accounts for memory impairments often seen in elderly people and how Abeta affects this relationship. Using tau-specific and Abeta-specific positron emission tomography tracers, we show that in vivo MTL tau pathology is associated with episodic-memory performance and MTL atrophy in cognitively normal adults, independent of Abeta. Our data point to MTL tau pathology, particularly in the entorhinal cortex, as a substrate of age-related episodic-memory loss. PMID- 29192127 TI - Compressive Temporal Summation in Human Visual Cortex. AB - Combining sensory inputs over space and time is fundamental to vision. Population receptive field models have been successful in characterizing spatial encoding throughout the human visual pathways. A parallel question, how visual areas in the human brain process information distributed over time, has received less attention. One challenge is that the most widely used neuroimaging method, fMRI, has coarse temporal resolution compared with the time-scale of neural dynamics. Here, via carefully controlled temporally modulated stimuli, we show that information about temporal processing can be readily derived from fMRI signal amplitudes in male and female subjects. We find that all visual areas exhibit subadditive summation, whereby responses to longer stimuli are less than the linear prediction from briefer stimuli. We also find fMRI evidence that the neural response to two stimuli is reduced for brief interstimulus intervals (indicating adaptation). These effects are more pronounced in visual areas anterior to V1-V3. Finally, we develop a general model that shows how these effects can be captured with two simple operations: temporal summation followed by a compressive nonlinearity. This model operates for arbitrary temporal stimulation patterns and provides a simple and interpretable set of computations that can be used to characterize neural response properties across the visual hierarchy. Importantly, compressive temporal summation directly parallels earlier findings of compressive spatial summation in visual cortex describing responses to stimuli distributed across space. This indicates that, for space and time, cortex uses a similar processing strategy to achieve higher-level and increasingly invariant representations of the visual world.SIGNIFICANCE STATEMENT Combining sensory inputs over time is fundamental to seeing. Two important temporal phenomena are summation, the accumulation of sensory inputs over time, and adaptation, a response reduction for repeated or sustained stimuli. We investigated these phenomena in the human visual system using fMRI. We built predictive models that operate on arbitrary temporal patterns of stimulation using two simple computations: temporal summation followed by a compressive nonlinearity. Our new temporal compressive summation model captures (1) subadditive temporal summation, and (2) adaptation. We show that the model accounts for systematic differences in these phenomena across visual areas. Finally, we show that for space and time, the visual system uses a similar strategy to achieve increasingly invariant representations of the visual world.

AB - Zinc is a transition metal that has a long history of use as an anti-inflammatory agent. It also soothes pain sensations in a number of animal models. However, the effects and mechanisms of zinc on chemotherapy-induced peripheral neuropathy remain unknown. Here we show that locally injected zinc markedly reduces neuropathic pain in male and female mice induced by paclitaxel, a chemotherapy drug, in a TRPV1-dependent manner. Extracellularly applied zinc also inhibits the function of TRPV1 expressed in HEK293 cells and mouse DRG neurons, which requires the presence of zinc-permeable TRPA1 to mediate entry of zinc into the cytoplasm. Moreover, TRPA1 is required for zinc-induced inhibition of TRPV1-mediated acute nociception. Unexpectedly, zinc transporters, but not TRPA1, are required for zinc-induced inhibition of TRPV1-dependent chronic neuropathic pain produced by paclitaxel. Together, our study demonstrates a novel mechanism underlying the analgesic effect of zinc on paclitaxel-induced neuropathic pain that relies on the function of TRPV1.SIGNIFICANCE STATEMENT The chemotherapy-induced peripheral neuropathy is a major limiting factor affecting the chemotherapy patients. There is no effective treatment available currently. We demonstrate that zinc prevents paclitaxel-induced mechanical hypersensitivity via inhibiting the TRPV1 channel, which is involved in the sensitization of peripheral nociceptors in chemotherapy. Zinc transporters in DRG neurons are required for the entry of zinc into the intracellular side, where it inhibits TRPV1. Our study provides insight into the mechanism underlying the pain-soothing effect of zinc and suggests that zinc could be developed to therapeutics for the treatment of chemotherapy-induced peripheral neuropathy.

PMID- 29192134 TI - Poly[n]catenanes: Synthesis of molecular interlocked chains. AB - As the macromolecular version of mechanically interlocked molecules, mechanically interlocked polymers are promising candidates for the creation of sophisticated molecular machines and smart soft materials. Poly[n]catenanes, where the molecular chains consist solely of interlocked macrocycles, contain one of the highest concentrations of topological bonds. We report, herein, a synthetic approach toward this distinctive polymer architecture in high yield (~75%) via efficient ring closing of rationally designed metallosupramolecular polymers. Light-scattering, mass spectrometric, and nuclear magnetic resonance characterization of fractionated samples support assignment of the high-molar mass product (number-average molar mass ~21.4 kilograms per mole) to a mixture of linear poly[7-26]catenanes, branched poly[13-130]catenanes, and cyclic poly[4 7]catenanes. Increased hydrodynamic radius (in solution) and glass transition temperature (in bulk materials) were observed upon metallation with Zn2. PMID- 29192133 TI - Synthetic transcription elongation factors license transcription across repressive chromatin. AB - The release of paused RNA polymerase II into productive elongation is highly regulated, especially at genes that affect human development and disease. To exert control over this rate-limiting step, we designed sequence-specific synthetic transcription elongation factors (Syn-TEFs). These molecules are composed of programmable DNA-binding ligands flexibly tethered to a small molecule that engages the transcription elongation machinery. By limiting activity to targeted loci, Syn-TEFs convert constituent modules from broad spectrum inhibitors of transcription into gene-specific stimulators. Here we present Syn-TEF1, a molecule that actively enables transcription across repressive GAA repeats that silence frataxin expression in Friedreich's ataxia, a terminal neurodegenerative disease with no effective therapy. The modular design of Syn-TEF1 defines a general framework for developing a class of molecules that license transcription elongation at targeted genomic loci. PMID- 29192135 TI - Encephalocraniocutaneous Lipomatosis: Haberland Syndrome. AB - BACKGROUND Encephalocraniocutaneous lipomatosis (ECCL) was first announced as a new type of ectomesodermal dysgenesis in 1970 by Haberland and Perou. ECCL was first described in 1970, and approximately 60 cases have been reported since then. The classic triad of ECCL are skin, ocular, and central nervous system involvement, including conditions such as unilateral porencephalic cyst, ipsilateral lipomatous hamartoma of the scalp-eyelids-eye globe, cortical atrophy, cranial asymmetry, developmental delay, seizures, mental retardation, and spasticity of the contralateral limbs. The dermatological hallmark is a hairless fatty tissue nevus of the scalp called nevus psiloliparus. CASE REPORT An 11-year-old right-handed boy, born at full term, was referred to our clinic. His family had no consanguinity or history of neurocutaneous disease. The patient's physical examination revealed a large hairless lesion on the right frontoparietal scalp called nevus psiloliparus. Beginning from the birth, a dermolipoma (an uncommon benign tumor) was reported to have occurred on the conjunctiva, mostly ipsilateral in his right eye and present on the ipsilateral side of the neurological abnormalities shown on magnetic resonance imaging and computed tomography. The patient had muscle weakness in left upper and lower extremities. He had a mild form of mental retardation. CONCLUSIONS There is no specific treatment for ECCL. Management of ECCL is usually symptomatic. Surgical correction of a cutaneous lesion can be performed for cosmetic improvement. An early diagnosis of ECCL allows for early symptom treatment and improved patient quality of life. PMID- 29192136 TI - Up-Regulated Maternal Embryonic Leucine Zipper Kinase Predicts Poor Prognosis of Hepatocellular Carcinoma Patients in a Chinese Han Population. AB - BACKGROUND Maternal embryonic leucine zipper kinase (MELK) has been implicated in various types of tumors, but its expression profile and clinicopathologic significance in hepatocellular carcinoma (HCC) in Chinese Han people remains unknown. Therefore, this study attempted to investigate the expression pattern of MELK in HCC tissues obtained from a Chinese Han population. MATERIAL AND METHODS The expression of MELK, from RNA to protein levels, in HCC or disease-free human liver tissues was evaluated using quantitative real-time polymerase chain reaction assays and immunohistochemistry staining, and its prognostic significance was determined based on its impact on HCC patients' survival. RESULTS We found that HCC tissues expressed a higher level of MELK RNA than non tumor tissues in tumor-related public databases (P<0.001). Hence, we assessed MELK mRNA expression within 32 HCC samples and their adjacent non-tumorous liver tissues in our center. Subsequently, MELK protein expression was evaluated within 101 HCC specimens and 40 disease-free liver tissues. Notably, it revealed that high MELK protein expression was significantly related with tumor number, tumor size, higher pathological tumor-nodule-metastasis stage, vascular invasion, and recurrence (P<0.05, all). Furthermore, elevated MELK protein expression was correlated with decreased overall survival and disease-free survival (P=0.004 and P=0.002, respectively). Univariate and multivariate analysis results show that MELK protein may serve as an independent prognostic indicator for determining prognosis of HCC patients. CONCLUSIONS We found that, in a Chinese Han population, MELK was highly expressed within HCC tissues from RNA to protein levels, and may be a potential independent prognostic biomarker for HCC patients. PMID- 29192137 TI - Application of Fully Covered Self-Expandable Metallic Stents with and without Antimigration Waist Versus Repeated Plastic Biliary Stent Placement in Management of Anastomotic Biliary Strictures After Orthotopic Liver Transplantation. AB - BACKGROUND Standard methods for endoscopic retrograde cholangiopancreatography (ERCP) management of anastomotic strictures (AS) after OLT includes repeated balloon dilation of the stricture with subsequent insertion of a plastic biliary stent (PBS). In post-OLT patients not responding to standard endoscopic treatment, the placement of fully covered self-expanding metal stents (FCSEMS) is a valid alternative to surgical treatment. The aim of this study was to compare the results of new FCSEMS implantation with the standard ERCP stricture management protocol and with conventional FCSEMS insertion. MATERIAL AND METHODS This retrospective study involved 39 post-OLT patients with confirmed diagnosis of biliary AS. Enrolled subjects were divided into 2 groups: the FCSEMS group (study group) and the PBS group (control group). The study group was divided into 2 subgroups: the conventional FCSEMS group and the new-type FCSEMS group. RESULTS Stricture recurrence after PBS placement was observed in 36.36% of controls and in only 9.52% of study group members (P=0.170). Recurrence rates in patients after conventional FCSEMS and new type FCSEMS implantation was similar (10% vs. 9.09%; P=0.501). The applied treatment was successful in 82.61% of study group members and only 43.75% of controls (P=0.029). Success rates of conventional FCSEMS and new-type SEMS insertion did not differ significantly (81.82% vs. 83.33%, P=0.649). There was no statistically significant difference in complication rates between groups (P=0.879). CONCLUSIONS Implantation of FCSEMS is more effective than repeated balloon dilatation of AS with subsequent PBS placement and is they have similar complication rates. Application of new-type FCSEMS gives results comparable to conventional FCSEMS. PMID- 29192138 TI - Publisher Correction: Multi-orbital charge transfer at highly oriented organic/metal interfaces.

AB - Regulation of mRNA splicing, processing and stability is increasingly recognized as a critical control point in dynamically altering gene expression during stress or disease. Very little is understood of this process in heart failure. Here, we show that BEX1 is a heart failure-induced gene functioning as an mRNA-associated protein that enhances expression of a subset of cardiac disease-promoting genes. Modeling the increase in BEX1 that occurs in disease, cardiac-specific BEX1 transgenic mice show worse cardiac disease with stress stimulation, whereas Bex1 gene-deleted mice are protected from heart failure-promoting insults. Proteomic and interactive screening assays show that BEX1 is part of a large ribonucleoprotein processing complex involved in regulating proinflammatory mRNA expression in the heart. Specifically, induction of BEX1 augments the stability and expression of AU-rich element containing mRNAs typically found within proinflammatory genes. Thus, BEX1 functions as an mRNA-dependent effector that augments pathology-promoting gene expression during heart failure. PMID- 29192140 TI - The gibberellin GID1-DELLA signalling module exists in evolutionarily ancient conifers. AB - Gibberellins (GAs) participate in controlling various aspects of basic plant growth responses. With the exception of bryophytes, GA signalling in land plants, such as lycophytes, ferns and angiosperms, is mediated via GIBBERELLIN INSENSITIVE DWARF1 (GID1) and DELLA proteins. To explore whether this GID1-DELLA mechanism is present in pines, we cloned an orthologue (PtGID1) of Arabidopsis AtGID1a and two putative DELLA proteins (PtDPL; PtRGA) from Pinus tabuliformis, a widespread indigenous conifer species in China, and studied their recombinant proteins. PtGID1 shares with AtGID1a the conserved HSL motifs for GA binding and an N-terminal feature that are essential for interaction with DELLA proteins. Indeed, A. thaliana 35S:PtGID1 overexpressors showed a strong GA-hypersensitive phenotype compared to the wild type. Interactions between PtGID1 and PtDELLAs, but also interactions between the conifer-angiosperm counterparts (i.e. between AtGID1 and PtDELLAs and between PtGID1 and AtDELLA), were detected in vivo. This demonstrates that pine has functional GID1-DELLA components. The Delta17-domains within PtDPL and PtRGA were identified as potential interaction sites within PtDELLAs. Our results show that PtGID1 has the ability to interact with DELLA and functions as a GA receptor. Thus, a GA-GID1-DELLA signalling module also operates in evolutionarily ancient conifers. PMID- 29192141 TI - Colloidal shuttles for programmable cargo transport. AB - The active transport of cargo molecules within cells is essential for life. Developing synthetic strategies for cargo control in living or inanimate thermal systems could lead to powerful tools to manipulate chemical gradients at the microscale and thus drive processes out of equilibrium to realize work. Here we demonstrate a colloidal analog of the complex biological shuttles responsible for molecular trafficking in cells. Our colloidal shuttles consist of magneto dielectric particles that are loaded with cargo particles or living cells through size-selective dielectrophoretic trapping using electrical fields. The loaded colloidal shuttle can be transported with magnetic field gradients before cargo is released at the target location by switching off the electrical field. Such spatiotemporal control over the distribution of chemically active cargo in a reversible fashion can be potentially exploited for fundamental biological research or for the development of novel technologies for advanced cell culturing, drug discovery and medical diagnosis. PMID- 29192142 TI - Ice nucleation triggered by negative pressure. AB - Homogeneous ice nucleation needs supercooling of more than 35 K to become effective. When pressure is applied to water, the melting and the freezing points both decrease. Conversely, melting and freezing temperatures increase under negative pressure, i.e. when water is stretched. This study presents an extrapolation of homogeneous ice nucleation temperatures from positive to negative pressures as a basis for further exploration of ice nucleation under negative pressure. It predicts that increasing negative pressure at temperatures below about 262 K eventually results in homogeneous ice nucleation while at warmer temperature homogeneous cavitation, i. e. bubble nucleation, dominates. Negative pressure occurs locally and briefly when water is stretched due to mechanical shock, sonic waves, or fragmentation. The occurrence of such transient negative pressure should suffice to trigger homogeneous ice nucleation at large supercooling in the absence of ice-nucleating surfaces. In addition, negative pressure can act together with ice-inducing surfaces to enhance their intrinsic ice nucleation efficiency. Dynamic ice nucleation can be used to improve properties and uniformity of frozen products by applying ultrasonic fields and might also be relevant for the freezing of large drops in rainclouds. PMID- 29192143 TI - Profiling of the transcriptional response to all-trans retinoic acid in breast cancer cells reveals RARE-independent mechanisms of gene expression. AB - Retinoids, derivatives of vitamin A, are key physiological molecules with regulatory effects on cell differentiation, proliferation and apoptosis. As a result, they are of interest for cancer therapy. Specifically, models of breast cancer have varied responses to manipulations of retinoid signaling. This study characterizes the transcriptional response of MDA-MB-231 and MDA-MB-468 breast cancer cells to retinaldehyde dehydrogenase 1A3 (ALDH1A3) and all-trans retinoic acid (atRA). We demonstrate limited overlap between ALDH1A3-induced gene expression and atRA-induced gene expression in both cell lines, suggesting that the function of ALDH1A3 in breast cancer progression extends beyond its role as a retinaldehyde dehydrogenase. Our data reveals divergent transcriptional responses to atRA, which are largely independent of genomic retinoic acid response elements (RAREs) and consistent with the opposing responses of MDA-MB-231 and MDA-MB-468 to in vivo atRA treatment. We identify transcription factors associated with each gene set. Manipulation of the IRF1 transcription factor demonstrates that it is the level of atRA-inducible and epigenetically regulated transcription factors that determine expression of target genes (e.g. CTSS, cathepsin S). This study provides a paradigm for complex responses of breast cancer models to atRA treatment, and illustrates the need to characterize RARE-independent responses to atRA in a variety of models. PMID- 29192145 TI - Self-medication by orang-utans (Pongo pygmaeus) using bioactive properties of Dracaena cantleyi. AB - Animals self-medicate using a variety of plant and arthropod secondary metabolites by either ingesting them or anointing them to their fur or skin apparently to repel ectoparasites and treat skin diseases. In this respect, much attention has been focused on primates. Direct evidence for self-medication among the great apes has been limited to Africa. Here we document self-medication in the only Asian great ape, orang-utans (Pongo pygmaeus), and for the first time, to our knowledge, the external application of an anti-inflammatory agent in animals. The use of leaf extracts from Dracaena cantleyi by orang-utan has been observed on several occasions; rubbing a foamy mixture of saliva and leaf onto specific parts of the body. Interestingly, the local indigenous human population also use a poultice of these leaves for the relief of body pains. We present pharmacological analyses of the leaf extracts from this species, showing that they inhibit TNFalpha-induced inflammatory cytokine production (E-selectin, ICAM 1, VCAM-1 and IL-6). This validates the topical anti-inflammatory properties of this plant and provides a possible function for its use by orang-utans. This is the first evidence for the deliberate external application of substances with demonstrated bioactive potential for self-medication in great apes. PMID- 29192144 TI - Downregulation of myostatin pathway in neuromuscular diseases may explain challenges of anti-myostatin therapeutic approaches. AB - Muscular dystrophies are characterized by weakness and wasting of skeletal muscle tissues. Several drugs targeting the myostatin pathway have been used in clinical trials to increase muscle mass and function but most showed limited efficacy. Here we show that the expression of components of the myostatin signaling pathway is downregulated in muscle wasting or atrophying diseases, with a decrease of myostatin and activin receptor, and an increase of the myostatin antagonist, follistatin. We also provide in vivo evidence in the congenital myotubular myopathy mouse model (knock-out for the myotubularin coding gene Mtm1) that a down-regulated myostatin pathway can be reactivated by correcting the underlying gene defect. Our data may explain the poor clinical efficacy of anti-myostatin approaches in several of the clinical studies and the apparent contradictory results in mice regarding the efficacy of anti-myostatin approaches and may inform patient selection and stratification for future trials. PMID- 29192146 TI - Cardiovascular Disease Risk Assessment in the United States and Low- and Middle Income Countries Using Predicted Heart/Vascular Age. AB - Almost 80% of the global burden of cardiovascular disease (CVD) occurs in low- and middle-income countries (LMICs). However, LMICs do not have well-established, low-technology ways to quantify and communicate CVD risk at population or individual levels. We examined predicted heart/vascular age (PHA) in six LMICs and the United States. Data were from CVD-free adults in World Health Organization Study on Global Aging and Adult Health (n = 29094) and US National Health and Nutritional Examination Survey (n = 6726). PHA was calculated using the non-laboratory Framingham CVD risk equation. High excess PHA (HEPHA) was defined as the differences between PHA and chronological age >5 years. Logistic regression models were used to identify factors associated with HEPHA. Age standardized prevalence of HEPHA was higher in Russia 52%; China 56%; Mexico 59%; and South Africa 65% compared to the US 45%, Ghana 36%; and India 38%. In LMICs, higher income, being divorced/widowed, alcohol intake and abdominal obesity had higher odds of HEPHA; higher education, fruit intake and physical activity had lower odds of HEPHA. The use of PHA may offer a useful avenue to communicate CVD risk. Interventions tailored at socioeconomic and cultural factors that influence CVD risk factors may be necessary to prevent CVD in LMICs. PMID- 29192147 TI - Protein crowding and lipid complexity influence the nanoscale dynamic organization of ion channels in cell membranes. AB - Cell membranes are crowded and complex environments. To investigate the effect of protein-lipid interactions on dynamic organization in mammalian cell membranes, we have performed coarse-grained molecular dynamics simulations containing >100 copies of an inwardly rectifying potassium (Kir) channel which forms specific interactions with the regulatory lipid phosphatidylinositol 4,5-bisphosphate (PIP2). The tendency of protein molecules to cluster has the effect of organizing the membrane into dynamic compartments. At the same time, the diversity of lipids present has a marked effect on the clustering behavior of ion channels. Sub diffusion of proteins and lipids is observed. Protein crowding alters the sub diffusive behavior of proteins and lipids such as PIP2 which interact tightly with Kir channels. Protein crowding also affects bilayer properties, such as membrane undulations and bending rigidity, in a PIP2-dependent manner. This interplay between the diffusion and the dynamic organization of Kir channels may have important implications for channel function. PMID- 29192148 TI - The importance of parameter choice in modelling dynamics of the eye lens. AB - The lens provides refractive power to the eye and is capable of altering ocular focus in response to visual demand. This capacity diminishes with age. Current biomedical technologies, which seek to design an implant lens capable of replicating the function of the biological lens, are unable as yet to provide such an implant with the requisite optical quality or ability to change the focussing power of the eye. This is because the mechanism of altering focus, termed accommodation, is not fully understood and seemingly conflicting theories require experimental support which is difficult to obtain from the living eye. This investigation presents finite element models of the eye lens based on data from human lenses aged 16 and 35 years that consider the influence of various modelling parameters, including material properties, a wide range of angles of force application and capsular thickness. Results from axisymmetric models show that the anterior and posterior zonules may have a greater impact on shape change than the equatorial zonule and that choice of capsular thickness values can influence the results from modelled simulations. PMID- 29192149 TI - Transcription factor repertoire in Ashwagandha (Withania somnifera) through analytics of transcriptomic resources: Insights into regulation of development and withanolide metabolism. AB - Transcription factors (TFs) are important regulators of cellular and metabolic functions including secondary metabolism. Deep and intensive RNA-seq analysis of Withania somnifera using transcriptomic databases provided 3532 annotated transcripts of transcription factors in leaf and root tissues, belonging to 90 different families with major abundance for WD-repeat (174 and 165 transcripts) and WRKY (93 and 80 transcripts) in root and leaf tissues respectively, followed by that of MYB, BHLH and AP2-ERF. Their detailed comparative analysis with Arabidopsis thaliana, Capsicum annum, Nicotiana tabacum and Solanum lycopersicum counterparts together gave interesting patterns. However, no homologs for WsWDR representatives, LWD1 and WUSCHEL, were observed in other Solanaceae species. The data extracted from the sequence read archives (SRA) in public domain databases were subjected to re-annotation, re-mining, re-analysis and validation for dominant occurrence of WRKY and WD-repeat (WDR) gene families. Expression of recombinant LWD1 and WUSCHEL proteins in homologous system led to enhancements in withanolide content indicating their regulatory role in planta in the biosynthesis. Contrasting expression profiles of WsLWD1 and WsWUSCHEL provided tissue-specific insights for their participation in the regulation of developmental processes. The in-depth analysis provided first full-spectrum and comparative characteristics of TF-transcripts across plant species, in the perspective of integrated tissue-specific regulation of metabolic processes including specialized metabolism. PMID- 29192151 TI - Spatially resolved Raman spectroscopy of defects, strains, and strain fluctuations in domain structures of monolayer graphene. AB - We report spatially resolved Raman scattering results of polycrystalline monolayer graphene films to study the effects of defects, strains, and strain fluctuations on the electrical performance of graphene. Two-dimensional Raman images of the integrated intensities of the G and D peaks (I G and I D) were used to identify the graphene domain boundaries. The domain boundaries were also identified using Raman images of I D/I G and I 2D/I G ratios and 2D spectral widths. Interestingly, the I D maps showed that the defects within individual domains significantly increased for the graphene with large domain size. The correlation analysis between the G and 2D peak energies showed that biaxial tensile strain was more developed in the graphene with large domain size than in the graphene with small domain size. Furthermore, spatial variations in the spectral widths of the 2D peaks over the graphene layer showed that strain fluctuations were more pronounced in the graphene with large domain size. It was observed that the mobility (sheet resistance) was decreased (increased) for the graphene with large domain size. The degradation of the electrical transport properties of the graphene with large domain size is mainly due to the defects, tensile strains, and local strain fluctuations within the individual domains. PMID- 29192150 TI - Directed self-assembly of fluorescence responsive nanoparticles and their use for real-time surface and cellular imaging. AB - Directed self-assemblies in water are known as the most efficient means of forming complex higher ordered structures in nature. Here we show a straightforward and robust method for particle assembly which utilises the amphiphilic tri-block co-polymer poloxamer-188 and a hydrophobic fluorophore as the two designer components, which have a built-in ability to convey spatial and temporal information about their surroundings to an observer. Templating of particle self-assembly is attributed to interactions between the fluorophore and hydrophobic segment of the poloxamer. Particle fluorescence in water is quenched but can be induced to selectively switch on in response to temperature, surface adsorption and cellular uptake. The ability of the particles to dynamically modulate emission intensity can be exploited for selective labelling and real time imaging of drug crystal surfaces, natural fibres and insulin fibrils, and cellular delivery. As particle solutions are easily prepared, further applications for this water-based NIR-fluorescent paint are anticipated. PMID- 29192152 TI - One small edit for humans, one giant edit for humankind? Points and questions to consider for a responsible way forward for gene editing in humans. AB - Gene editing, which allows for specific location(s) in the genome to be targeted and altered by deleting, adding or substituting nucleotides, is currently the subject of important academic and policy discussions. With the advent of efficient tools, such as CRISPR-Cas9, the plausibility of using gene editing safely in humans for either somatic or germ line gene editing is being considered seriously. Beyond safety issues, somatic gene editing in humans does raise ethical, legal and social issues (ELSI), however, it is suggested to be less challenging to existing ethical and legal frameworks; indeed somatic gene editing is already applied in (pre-) clinical trials. In contrast, the notion of altering the germ line or embryo such that alterations could be heritable in humans raises a large number of ELSI; it is currently debated whether it should even be allowed in the context of basic research. Even greater ELSI debates address the potential use of germ line or embryo gene editing for clinical purposes, which, at the moment is not being conducted and is prohibited in several jurisdictions. In the context of these ongoing debates surrounding gene editing, we present herein guidance to further discussion and investigation by highlighting three crucial areas that merit the most attention, time and resources at this stage in the responsible development and use of gene editing technologies: (1) conducting careful scientific research and disseminating results to build a solid evidence base; (2) conducting ethical, legal and social issues research; and (3) conducting meaningful stakeholder engagement, education and dialogue.

PMID- 29192155 TI - Trehalose significantly enhances the recovery of serum and serum exosomal miRNA from a paper-based matrix. AB - The preservation of nucleic acids from clinical samples is critical to facilitate accurate molecular diagnosis. The use of a paper matrix, Flinders Technology Associates (FTA) Elute cards, to archive DNA and viral RNA is well-documented. However, the feasibility of FTA Elute cards for archiving serum and serum exosomal microRNAs (miRNAs) remains unclear. Here, we performed a comprehensive evaluation of FTA Elute cards for miRNA storage and recovery in different pre analytical conditions. The recovery of serum miRNA dry-spotted on FTA Elute cards by direct elution with water at high temperature was poor. However, serum miRNAs dry-spotted on the cards were isolated with about 40% yield when using QIAzol lysis reagent and recovery was improved remarkably (>80%) upon extraction from cards pre-treated with trehalose. miRNAs stored on the cards remained stable at room temperature and can be kept for prolonged periods. Furthermore, miRNAs could be similarly recovered from serum exosomes dry-spotted on the cards. Importantly, when using sera from gastric cancer (GC) patients, the miRNAs were efficiently recovered from trehalose pre-treated cards without affecting their representation. Collectively, we have demonstrated the potential of FTA Elute cards to archive serum and serum exosomal miRNAs, making it useful for biomarker discovery and diagnostics. PMID- 29192156 TI - Unbiased Quantitative Proteomics Reveals a Crucial Role of the Allergen Context for the Activation of Human Dendritic Cells. AB - Worldwide, more than 1 billion people suffer from allergic diseases. However, until now it is not fully understood how certain proteins can induce allergic immune responses, while others cannot. Studies suggest that allergenicity is a process not only determined by properties of the allergen itself but also by costimulatory factors, that are not classically associated with allergic reactions. To investigate the allergenicity of the major birch pollen allergen Bet v 1 and the impact of adjuvants associated with pollen, e.g. lipopolysaccharide (LPS), we performed quantitative proteome analysis to study the activation of monocyte-derived dendritic cells (moDCs). Thus, we treated cells with birch pollen extract (BPE), recombinant Bet v 1, and LPS followed by proteomic profiling via high-performance liquid chromatography and tandem mass spectrometry (HPLC-MS/MS) using isobaric labelling. Enrichment and pathway analysis revealed the influence of regulated proteins especially in cytokine signalling and dendritic cell activation. We found highly regulated, but differentially expressed proteins after treatment with BPE and LPS, whereas the cellular response to Bet v 1 was limited. Our findings lead to the conclusion that Bet v 1 needs a specific "allergen context" involving cofactors apart from LPS to induce an immune response in human moDCs.

AB - A synthetic method for diversely substituted tetrahydropyrrolo[1,2-a]quinolines was developed via CuCl-catalyzed cascade transformation of internal aminoalkynes with alkynes under microwave- irradiation. PMID- 29192157 TI - Linking functional connectivity and dynamic properties of resting-state networks. AB - Spontaneous brain activity is organized into resting-state networks (RSNs) involved in internally-guided, higher-order mental functions (default mode, central executive and salience networks) and externally-driven, specialized sensory and motor processing (auditory, visual and sensorimotor networks). RSNs are characterized by their functional connectivity in terms of within-network cohesion and between-network integration, and by their dynamic properties in terms of synchrony and metastability. We examined the relationship between functional connectivity and dynamic network features using fMRI data and an anatomically constrained Kuramoto model. Extrapolating from simulated data, synchrony and metastability across the RSNs emerged at coupling strengths of 5 <= k <= 12. In the empirical RSNs, higher metastability and synchrony were respectively associated with greater cohesion and lower integration. Consistent with their dual role in supporting both sustained and diverse mental operations, higher-order RSNs had lower metastability and synchrony. Sensory and motor RSNs showed greater cohesion and metastability, likely to respectively reflect their functional specialization and their greater capacity for altering network states in response to multiple and diverse external demands. Our findings suggest that functional and dynamic RSN properties are closely linked and expand our understanding of the neural architectures that support optimal brain function. PMID- 29192159 TI - Light and Capillary Waves Propagation in Water Fibers. AB - The confinement of light and sound, while they are traveling in fibers, enables a variety of light-matter interactions. Therefore, it is natural to ask if fibers can also host capillary waves. Capillary waves are similar to those we see when throwing a stone into a puddle. Such capillary waves are prohibited in microfluidic devices where the liquid is bounded by solid walls. In contrast, we have fabricated fibers, which are made entirely from water and are suspended in air. The water fiber can therefore move, e.g. in a resonant mode that reassembles the motion of a guitar string. In our experiment, light guided through the water fiber allows optical interrogation of is capillary oscillations. Co-confining two important oscillations in nature: capillary and electromagnetic, might allow a new type of devices called Micro-Electro-Capillary-Systems [MECS]. The softness of MECS is a million times higher when compared to what the current solid-based technology permits, which accordingly improves MECS response to minute forces such as small changes in acceleration. Additionally, MECS might allow new ways to optically interrogate viscosity and surface tension, as well as their changes caused by introducing an analyte into the system. PMID- 29192160 TI - A Novel Human Systemic Lupus Erythematosus Model in Humanised Mice. AB - Mouse models have contributed to the bulk of knowledge on Systemic Lupus Erythematosus (SLE). Nevertheless, substantial differences exist between human and mouse immune system. We aimed to establish and characterise a SLE model mediated by human immune system. Injection of pristane into immunodeficient mice reconstituted with human immune system (humanised mice) recapitulated key SLE features, including: production of human anti-nuclear autoantibodies, lupus nephritis, and pulmonary serositis. There was a reduction in the number of human lymphocytes in peripheral blood, resembling lymphopenia in SLE patients. Concurrently, B cells and T cells were systemically hyperactivated, with a relative expansion of CD27+ and CD27-IgD- memory B cells, increased number of plasmablasts/plasma cells, and accumulation of effector memory T cells. There was also an increased production of human pro-inflammatory cytokines, including: IFN gamma, IL-8, IL-18, MCP-1, and IL-6, suggesting their role in SLE pathogenesis. Increased expression of type I IFN signature genes was also found in human hepatocytes. Altogether, we showed an SLE model that was mediated by human immune system, and which recapitulated key clinical and immunological SLE features. The advancements of humanised mice SLE model would provide an in vivo platform to facilitate translational studies and pre-clinical evaluations of human-specific mechanisms and immunotherapies. PMID- 29192161 TI - Unusual scaling laws for plasmonic nanolasers beyond the diffraction limit. AB - Plasmonic nanolasers are a new class of amplifiers that generate coherent light well below the diffraction barrier bringing fundamentally new capabilities to biochemical sensing, super-resolution imaging, and on-chip optical communication. However, a debate about whether metals can enhance the performance of lasers has persisted due to the unavoidable fact that metallic absorption intrinsically scales with field confinement. Here, we report plasmonic nanolasers with extremely low thresholds on the order of 10 kW cm-2 at room temperature, which are comparable to those found in modern laser diodes. More importantly, we find unusual scaling laws allowing plasmonic lasers to be more compact and faster with lower threshold and power consumption than photonic lasers when the cavity size approaches or surpasses the diffraction limit. This clarifies the long-standing debate over the viability of metal confinement and feedback strategies in laser technology and identifies situations where plasmonic lasers can have clear practical advantage. PMID- 29192162 TI - Environmental conditions limit attractiveness of a complex sexual signal in the tungara frog. AB - Animals choosing particular display sites often balance sexual and natural selection pressures. Here we assess how physical properties of display sites can alter this balance by influencing signal production and attractiveness of the tungara frog (Physalaemus pustulosus). Males that call from very shallow water bodies (few mm depth) benefit from reduced predation risk, but by manipulating water levels, we show that this comes at a cost of reduced attractiveness to females. Our data show that calling from shallower water reduces a male's ability to float, limits the inflation of his vocal sac, and consequently reduces signal conspicuousness in terms of amplitude and complexity. Our results demonstrate that display site properties can set limits on signal production and attractiveness and may hence influence signal evolution. Signallers may shift between sites or engineer their display location, which can play a crucial role in signal divergence and speciation, particularly in a rapidly changing world. PMID- 29192163 TI - Investigating quantum metrology in noisy channels. AB - Quantum entanglement lies at the heart of quantum information and quantum metrology. In quantum metrology, with a colossal amount of quantum Fisher information (QFI), entangled systems can be ameliorated to be a better resource scheme. However, noisy channels affect the QFI substantially. This research work seeks to investigate how QFI of N-qubit Greenberger-Horne-Zeilinger (GHZ) state is affected when subjected to decoherence channels: bit-phase flip (BPF) and generalize amplitude damping (GAD) channels, which can be induced experimentally. We determine the evolution under these channels, deduce the eigenvalues, and then derive the QFI. We found that when there is no interaction with the environment, the Heisenberg limit can be achieved via rotations along the z direction. It has been shown that in BPF channel, the maximal mean QFI of the N-qubit GHZ state ([Formula: see text]) dwindles as decoherence rate (p B ) increases due to flow of information from the system to the environment, until p B = 0.5, then revives to form a symmetric around p B = 0.5. Thus, p B > 0.5 leads to a situation where more noise yields more efficiency. We found that in GAD channel, at finite temperature, QFIs decay more rapidly than at zero temperature. Our results also reveal that QFI can be enhanced by adjusting the temperature of the environment. PMID- 29192164 TI - Low-dose levels of bisphenol A inhibit telomerase via ER/GPR30-ERK signalling, impair DNA integrity and reduce cell proliferation in primary PBMC. AB - Controversy exists about the human health risk of environmental exposure to bisphenol A (BPA). Telomerase activity is emerging both as biomarker and contributing factor for age-related diseases. The effects of BPA exposure at 1 1000 nM on telomerase, DNA integrity and cell proliferation were investigated in PBMC from human donors. Telomerase activity was determined by TRAP-ELISA assay and mRNA expression by qRT-PCR. Mechanistic studies were carried out on the ER/GPR30-ERK pathway using specific inhibitors/antagonists, the comet assay to quantify DNA damage and flow cytometry for cell proliferation. 24 h BPA exposure inhibited telomerase in a non-monotonic pattern with a peak inhibition of 32% at 1 nM (p <= 0.01). A significant telomerase inhibition was evident at 1 h after exposure with a minimum at 6 h. Elevated levels of DNA damage frequency and decrease in cell proliferation were evident upon long-term exposure. The results further demonstrate that BPA triggered rapidly an ER/GPR30-ERK transduction pathway that leads to decreased telomerase activity in human PBMC. This is the first study to demonstrate adverse impact of BPA at levels of current human exposure on telomerase in normal cells, mediated by ER/GPR30-ERK. The results suggest a potentially harmful influence of BPA on immune cells and should be addressed in future studies. PMID- 29192165 TI - Fine control of metal concentrations is necessary for cells to discern zinc from cobalt. AB - Bacteria possess transcription factors whose DNA-binding activity is altered upon binding to specific metals, but metal binding is not specific in vitro. Here we show that tight regulation of buffered intracellular metal concentrations is a prerequisite for metal specificity of Zur, ZntR, RcnR and FrmR in Salmonella Typhimurium. In cells, at non-inhibitory elevated concentrations, Zur and ZntR, only respond to Zn(II), RcnR to cobalt and FrmR to formaldehyde. However, in vitro all these sensors bind non-cognate metals, which alters DNA binding. We model the responses of these sensors to intracellular-buffered concentrations of Co(II) and Zn(II) based upon determined abundances, metal affinities and DNA affinities of each apo- and metalated sensor. The cognate sensors are modelled to respond at the lowest concentrations of their cognate metal, explaining specificity. However, other sensors are modelled to respond at concentrations only slightly higher, and cobalt or Zn(II) shock triggers mal-responses that match these predictions. Thus, perfect metal specificity is fine-tuned to a narrow range of buffered intracellular metal concentrations. PMID- 29192166 TI - Spindle associated membrane protein 1 (Samp1) is required for the differentiation of muscle cells. AB - Muscles are developed and regenerated in a differentiation process called myogenesis, which involves components of the nuclear envelope. We have investigated Samp1 (Spindle Associated Membrane Protein 1), a transmembrane nuclear envelope protein, which interacts with emerin and lamin A, both of which are linked to Emery-Dreifuss muscular dystrophy (EDMD). We found that the levels of Samp1 increased seven-fold during differentiation of mouse C2C12 muscle progenitor cells. To test if Samp1 could have a role in myogenesis we developed stable C2C12 knockdown cell lines expressing short hairpin RNA targeting Samp1 expression. The Samp1 depleted C2C12 cells displayed normal mobility and normal distribution of emerin and lamin A. However, Samp1 depletion increased ERK signaling and completely blocked differentiation of C2C12 cells, which failed to express myogenic marker proteins and failed to form myotubes. The block in myogenesis in Samp1 depleted cells was completely rescued by ectopic expression of RNAi resistant human Samp1, showing that Samp1 is required for muscle differentiation. PMID- 29192168 TI - Investigating disordered many-body system with entanglement in momentum space. AB - We study the entanglement in momentum space of the ground state of a disordered one-dimensional fermion lattice model with attractive interaction. We observe two components in the entanglement spectrum, one of which is related to paired fermion entanglement and contributes to the long-range correlation in position space. The vanishing point of it indicates the localization phenomenon in the ground state of this model. Additionally, by method of entanglement spectrum, we provide a new evidence to show the transition of two phases induced by interaction, and find that this phase transition is not influenced by the disorder. Our result show key characteristics in entanglement for different phases in the system, and provide a novel perspective to understand localization phenomena. PMID- 29192167 TI - Partially native intermediates mediate misfolding of SOD1 in single-molecule folding trajectories. AB - Prion-like misfolding of superoxide dismutase 1 (SOD1) is associated with the disease ALS, but the mechanism of misfolding remains unclear, partly because misfolding is difficult to observe directly. Here we study the most misfolding prone form of SOD1, reduced un-metallated monomers, using optical tweezers to measure unfolding and refolding of single molecules. We find that the folding is more complex than suspected, resolving numerous previously undetected intermediate states consistent with the formation of individual beta-strands in the native structure. We identify a stable core of the protein that unfolds last and refolds first, and directly observe several distinct misfolded states that branch off from the native folding pathways at specific points after the formation of the stable core. Partially folded intermediates thus play a crucial role mediating between native and non-native folding. These results suggest an explanation for SOD1's propensity for prion-like misfolding and point to possible targets for therapeutic intervention. PMID- 29192169 TI - Face Dependence of Schottky Barriers Heights of Silicides and Germanides on Si and Ge. AB - Density functional supercell calculations of the Schottky barrier heights (SBH) of metal germanides and silicides on Si or Ge find that these vary with the facet, unlike those of elemental metals. In addition, silicides and germanides show a stronger dependence of their SBHs on the work function than those of elemental metals, as seen experimentally. Both effects are beyond the standard metal induced gap states model. NiSi2 is found to have a much lower SBH on n Si(100) than on n-Si(111), as seen experimentally. It is shown how such results can be used to design lower SBH contacts for n-Ge, which are needed technologically. The SBHs of the better behaved Si/silicide interfaces can be used to benchmark the behavior of the less well behaved Ge-germanide interfaces for this purpose. The dependence of the SBH of epitaxial Pb-Si(111) on its reconstruction is also covered. PMID- 29192170 TI - Monkeys share the neurophysiological basis for encoding sound periodicities captured by the frequency-following response with humans. AB - The extraction and encoding of acoustical temporal regularities are fundamental for human cognitive auditory abilities such as speech or beat entrainment. Because the comparison of the neural sensitivity to temporal regularities between human and animals is fundamental to relate non-invasive measures of auditory processing to their neuronal basis, here we compared the neural representation of auditory periodicities between human and non-human primates by measuring scalp recorded frequency-following response (FFR). We found that rhesus monkeys can resolve the spectrotemporal structure of periodic stimuli to a similar extent as humans by exhibiting a homologous FFR potential to the speech syllable /da/. The FFR in both species is robust and phase-locked to the fundamental frequency of the sound, reflecting an effective neural processing of the fast-periodic information of subsyllabic cues. Our results thus reveal a conserved neural ability to track acoustical regularities within the primate order. These findings open the possibility to study the neurophysiology of complex sound temporal processing in the macaque subcortical and cortical areas, as well as the associated experience-dependent plasticity across the auditory pathway in behaving monkeys. PMID- 29192171 TI - A strategy for effective latent HIV reactivation using subtherapeutic drug doses. AB - Cell state switches underlie a plethora of biological phenomena and disease treatment strategies. Hence the ability to efficiently switch states in a chosen direction is of central importance in a number of scenarios. Increasing the concentration of an effector that results in a given switch is often limited by side effects. Approaches are thus increasingly sought to bypass these constraints, increasing the frequency of state switching without increasing the frequency of the side effect. Here, we employ dynamical systems theory to uncover a simple strategy as to how to maximize the probability of reactivating latent Human immunodeficiency virus (HIV) whilst maintaining minimal side effects. We demonstrate that continuous supply of an effector is significantly more likely to result in a switch with minimal side effects than the same effector supplied in temporally discrete doses. Importantly this continual dosage is likely to occur far below the Minimum effective dose at a concentration that has classically been thought subtherapeutic. We therefore suggest that in many interventional settings there exists potential to reduce drug dose much further than has previously been thought possible yet still maintaining efficacy. PMID- 29192172 TI - Emergence of Quantum Critical Behavior in Metallic Quantum-Well States of Strongly Correlated Oxides. AB - Controlling quantum critical phenomena in strongly correlated electron systems, which emerge in the neighborhood of a quantum phase transition, is a major challenge in modern condensed matter physics. Quantum critical phenomena are generated from the delicate balance between long-range order and its quantum fluctuation. So far, the nature of quantum phase transitions has been investigated by changing a limited number of external parameters such as pressure and magnetic field. We propose a new approach for investigating quantum criticality by changing the strength of quantum fluctuation that is controlled by the dimensional crossover in metallic quantum well (QW) structures of strongly correlated oxides. With reducing layer thickness to the critical thickness of metal-insulator transition, crossover from a Fermi liquid to a non-Fermi liquid has clearly been observed in the metallic QW of SrVO3 by in situ angle-resolved photoemission spectroscopy. Non-Fermi liquid behavior with the critical exponent alpha = 1 is found to emerge in the two-dimensional limit of the metallic QW states, indicating that a quantum critical point exists in the neighborhood of the thickness-dependent Mott transition. These results suggest that artificial QW structures provide a unique platform for investigating novel quantum phenomena in strongly correlated oxides in a controllable fashion. PMID- 29192173 TI - Metric clusters in evolutionary games on scale-free networks. AB - The evolution of cooperation in social dilemmas in structured populations has been studied extensively in recent years. Whereas many theoretical studies have found that a heterogeneous network of contacts favors cooperation, the impact of spatial effects in scale-free networks is still not well understood. In addition to being heterogeneous, real contact networks exhibit a high mean local clustering coefficient, which implies the existence of an underlying metric space. Here we show that evolutionary dynamics in scale-free networks self organize into spatial patterns in the underlying metric space. The resulting metric clusters of cooperators are able to survive in social dilemmas as their spatial organization shields them from surrounding defectors, similar to spatial selection in Euclidean space. We show that under certain conditions these metric clusters are more efficient than the most connected nodes at sustaining cooperation and that heterogeneity does not always favor-but can even hinder cooperation in social dilemmas. PMID- 29192174 TI - Long-term climate change in the D-region. AB - Controversy exists over the potential effects of long-term increases in greenhouse gas concentrations on the ionospheric D-region at 60-90 km altitudes. Techniques involving in-situ rocket measurements, remote optical observations, and radio wave reflection experiments have produced conflicting results. This study reports a novel technique that analyses long-distance subionospheric very low frequency radiowave observations of the NAA 24.0 kHz transmitter, Cutler, Maine, made from Halley Station, Antarctica, over the period 1971-2016. The analysis is insensitive to any changes in the output power of the transmitter, compensates for the use of different data logging equipment, and can confirm the accuracy of the timing systems operated over the 45 year long record. A ~10% reduction in the scale size of the transmitter nighttime interference fringe pattern has been determined, taking into account the quasi-11 year solar cycle. Subionospheric radiowave propagation modeling suggests that the contraction of the interference fringe pattern about the mid-latitude NAA transmitter is due to a 3 km reduction in the effective height of the nighttime ionospheric D-region over the last 45 years. This is consistent with the effect of enhanced infra-red cooling by increasing greenhouse gases. PMID- 29192175 TI - Higher Platelet-to-Lymphocyte Ratio Increased the Risk of Sarcopenia in the Community-Dwelling Older Adults. AB - The platelet-to-lymphocyte ratio (PLR) has been extensively studied in oncologic diseases. However, the correlation between PLR and sarcopenia remains unknown. In this cross-sectional analysis, we enrolled 3,671 non-institutionalized individuals from the National Health and Nutrition Examination Survey (NHANES) III (1988-1994) aged >=60 years and whose complete blood counts (CBCs), body composition measurements, and related demographic information was available. Skeletal muscle mass was assessed using a previously published equation (including age, sex, height, and bioelectrical impedance analysis). PLR values were estimated based on laboratory data. Multiple linear and logistic regression analyses, quartile-based stratified odds ratio comparisons, and trend tests were performed. Elevations in serum PLR values were significantly associated with sarcopenia status and negatively associated with skeletal muscle index. After additionally adjusting for other covariates, the significant negative correlation remained; moreover, participants with highest serum PLR values (>=155) had 2.36 times greater risk of sarcopenia than those with lowest PLR values (<90; odds ratio (OR) = 2.36; 95% confidence interval (CI): 1.21-3.31; p < 0.01). Higher PLR levels are associated with a greater risk of sarcopenia in geriatric populations. Thus, PLR as an inexpensive and easily measurable parameter can be considered as an inflammatory biomarker for sarcopenia. PMID- 29192176 TI - PGC-1alpha levels correlate with survival in patients with stage III NSCLC and may define a new biomarker to metabolism-targeted therapy. AB - Lung cancer remains the leading cause of cancer-related death worldwide, with one third diagnosed with locally advanced (stage III) disease. Preoperative induction chemo-radiotherapy is key for the treatment of these patients, however conventional cisplatin based approaches has apparently reached a plateau of effectiveness. In the search for new therapies, the targeting of tumor metabolism is revealed as an interesting option to improve the patient's responses. Here we describe the importance of PGC-1alpha and GAPDH/MT-CO1 ratio levels as surrogates of the Warburg effect from a series of 28 stage III NSCLC patients, on PFS, OS and PET uptake. Moreover, our results show a great variability between tumors of different individuals, ranging from very glycolytic to more OXPHOS-dependent tumors, which compromises the success of therapies directed to metabolism. In this sense, using 3 different cell lines, we describe the relevance of Warburg effect on the response to metabolism-targeted therapies. Specifically, we show that the inhibitory effect of metformin on cell viability depends on cell's dependence on the OXPHOS system. The results on cell lines, together with the results of PGC-1alpha and GAPDH/MT-CO1 as biomarkers on patient's biopsies, would point out what type of patients would benefit more from the use of these drugs. PMID- 29192177 TI - Up-regulation of Interleukin-21 Contributes to Liver Pathology of Schistosomiasis by Driving GC Immune Responses and Activating HSCs in Mice. AB - The pathology of schistosome egg-induced liver granuloma, fibrosis and eventually liver scarring is complicated. CD4+ helper T (Th) cells play critical roles in both host humoral immunity and cellular immunity against parasitic infection and immunopathology in schistosomiasis. Follicular helper T (Tfh) cells are another specialized subset of Th cells and involved in infectious diseases. However, the immune regulatory mechanism of Tfh cells in severe liver pathology of schistosomiasis is still poorly understood. In this study, using a S. japonicum infected mouse model, we studied the dynamics and effects of Tfh cells in vivo and demonstrated that Tfh phenotype molecules ICOS, PD-1 and functional factor IL 21 were positively correlated with disease development by flow cytometry. Meanwhile, our results also showed that Tfh cells enriched in splenic germinal center (GC) and promoted B cells producing IgM with the progress of hepatic immunopathology by B-T co-culture experiments. More importantly, our data indicated that IL-21 contributed to the formation and development of hepatic egg granuloma and subsequent fibrosis by driving GC responses and activating HSCs by immunohistochemical detection and blocking assay in vitro. Our findings contribute to the better understanding of the immunopathogenesis of schistosomiasis and have implications for therapeutic intervention of hepatic fibrotic diseases. PMID- 29192178 TI - Characterisation of porous knitted titanium for replacement of intervertebral disc nucleus pulposus. AB - Effective restoration of human intervertebral disc degeneration is challenged by numerous limitations of the currently available spinal fusion and arthroplasty treatment strategies. Consequently, use of artificial biomaterial implant is gaining attention as a potential therapeutic strategy. Our study is aimed at investigating and characterizing a novel knitted titanium (Ti6Al4V) implant for the replacement of nucleus pulposus to treat early stages of chronic intervertebral disc degeneration. Specific knitted geometry of the scaffold with a porosity of 67.67 +/- 0.824% was used to overcome tissue integration failures. Furthermore, to improve the wear resistance without impairing original mechanical strength, electro-polishing step was employed. Electro-polishing treatment changed a surface roughness from 15.22 +/- 3.28 to 4.35 +/- 0.87 um without affecting its wettability which remained at 81.03 +/- 8.5 degrees . Subsequently, cellular responses of human mesenchymal stem cells (SCP1 cell line) and human primary chondrocytes were investigated which showed positive responses in terms of adherence and viability. Surface wettability was further enhanced to super hydrophilic nature by oxygen plasma treatment, which eventually caused substantial increase in the proliferation of SCP1 cells and primary chondrocytes. Our study implies that owing to scaffolds physicochemical and biocompatible properties, it could improve the clinical performance of nucleus pulposus replacement. PMID- 29192179 TI - CMScaller: an R package for consensus molecular subtyping of colorectal cancer pre-clinical models. AB - Colorectal cancers (CRCs) can be divided into four gene expression-based biologically distinct consensus molecular subtypes (CMS). This classification provides a potential framework for stratified treatment, but to identify novel CMS-drug associations, translation of the subtypes to pre-clinical models is essential. The currently available classifier is dependent on gene expression signals from the immune and stromal compartments of tumors and fails to identify the poor-prognostic CMS4-mesenchymal group in immortalized cell lines, patient derived organoids and xenografts. To address this, we present a novel CMS classifier based on a filtered set of cancer cell-intrinsic, subtype-enriched gene expression markers. This new classifier, referred to as CMScaller, recapitulated the subtypes in both in vitro and in vivo models (551 in total). Importantly, by analyzing public drug response data from patient-derived xenografts and cell lines, we show that the subtypes are predictive of response to standard CRC drugs. CMScaller is available as an R package. PMID- 29192180 TI - Clinical Application of Artificial Ascites in assisting CT-guided Percutaneous Cryoablation of Hepatic Tumors Adjacent to the Gastrointestinal Tract. AB - This study was to assess the safety and efficacy of artificial ascitetes in assisting CT-guided cryoablation of hepatic tumors adjacent to the gastrointestinal (GI) tract. A total of 84 patients with peripheral hepatic tumors adjacent to the GI tract, who were treated cryoablation, were included in this retrospective study. Of these 84 patients, cryoablation had been performed in 39 patients with 41 peripheral hepatic tumors. These were assisted by induction artificial ascites while 40 patients with 43 peripheral hepatic tumors underwent cryoablation without induction of ascites. The artificial ascites separation success rate, the cryoablation technique effectiveness, local tumor progression and complications were all evaluated. The results showed that the artificial ascites separation success rate for 41 hepatic tumors adjacent to the GI tract was 95% (39/41). Technique effectiveness of group I was achieved in 35 of 43 tumors (81.3%) after follow-up imaging three months after cryoablation. In group II, technique effectiveness was achieved in 39 of 41 tumors after follow-up imaging three months following cryoablation. No major complications were encountered in either of the two groups. Artificial ascites assisting in CT guided percutaneous cryoablation is a reliable and effective method for the treatment of hepatic tumors adjacent to the GI tract, and it can achieve a fine local control of such tumors. PMID- 29192181 TI - Raman-Deuterium Isotope Probing for in-situ identification of antimicrobial resistant bacteria in Thames River. AB - The emergence and widespread distribution of antimicrobial resistant (AMR) bacteria has led to an increasing concern with respect to potential environmental and public health risks. Culture-independent and rapid identification of AMR bacteria in-situ in complex environments is important in understanding the role of viable but non-culturable and antibiotic persistent bacteria and in revealing potential pathogens without waiting for colony formation. In this study, a culture-independent and non-destructive phenotyping approach, so called Raman Deuterium Stable Isotope Probing (Raman-DIP), was developed to identify AMR bacteria in the River Thames. It is demonstrated that Raman-DIP was able to accurately identify resistant and susceptible bacteria within 24 hours. The work shows that, in the River Thames, the majority of the bacteria (76 +/- 2%) were metabolically active, whilst AMR bacteria to carbenicillin, kanamycin and both two antibiotics were 35 +/- 5%, 28 +/- 3%, 25 +/- 1% of the total bacterial population respectively. Raman activated cell ejection (RACE) was applied to isolate single AMR bacteria for the first time, linking AMR phenotype (reistance to antibiotics) and genotype (DNA sequence). The sequences of the RACE sorted cells indicate that they were potential human pathogens Aeromonas sp., Stenotrophomonas sp. and an unculturable bacterium. This work demonstrates Raman DIP and RACE are effective culture-independent approach for rapid identification of AMR bacteria at the single cell level in their natural conditions. PMID- 29192182 TI - Precise optical modeling of quantum dots for white light-emitting diodes. AB - Quantum dots (QDs)-based white light-emitting diodes (QDs-WLEDs) have been attracting numerous attentions in lighting and flat panel display applications, by virtue of their high luminous efficacy and excellent color rendering ability. However, QDs' key optical parameters including scattering, absorption and anisotropy coefficients for optical modeling are still unclear, which are severely against the design and optimization of QDs-WLEDs. In this work, we proposed a new precise optical modeling approach towards QDs. Optical properties of QDs-polymer film were obtained for the first time, by combining double integrating sphere (DIS) system measurement with inverse adding doubling (IAD) algorithm calculation. The measured results show that the typical scattering, absorption and anisotropy coefficients of red emissive QDs are 2.9382 mm-1, 3.7000 mm-1 and 0.4918 for blue light, respectively, and 1.2490 mm-1, 0.6062 mm-1 and 0.5038 for red light, respectively. A Monte-Carlo ray-tracing model was set up for validation. With a maximum deviation of 1.16%, the simulated values quantitatively agree with the experimental results. Therefore, our approach provides an effective way for optical properties measurement and precise optical modeling of QDs for QDs-WLEDs.

Mutations in six different genes of Plasmodium falciparum (crt, mdr1, dhfr, dhps, ATPase6 and K-13 propeller) that confer resistance to chloroquine, sulphadoxine-pyrimethamine and artemisinin-based combination therapy were analyzed in samples from Chhattisgarh. Seventy-eight percent of the samples were found to have a pfcrt mutation (53% double, 24% triple and 1% single mutant), and 59% of pfmdr1 genes were found to have an N86Y mutation. Double mutations were recorded in pfdhfr gene among 76% of the samples while only 6% of the samples harbored mutant genotypes in pfdhps. No mutation was found in the K 13 propeller gene, while only one sample showed a mutant genotype for the PfATPase6 gene. The Tajima test confirmed that there is no role of evolutionary natural selection in drug resistance, and gene pairwise linkage of disequilibrium showed significant intragenic association. The high level of pfcrt mutations suggests that parasite resistance to chloroquine is almost at a fixed level, whereas resistance to SP is evolving in the population and parasites remain sensitive to artemisinin derivatives. These findings provide potential information and understanding of the evolution and spread of different drug resistance alleles in Chhattisgarh.

AB - The present study evaluated the activities of heart rate variability (HRV) and dorsolateral prefrontal cortex (DLPFC) in response to the presentation of affective pictures correlated with posttraumatic growth (PTG) among adults exposed to the Tianjin explosion incident. The participants who were directly involved in the Tianjin explosions were divided into control, post-traumatic stress disorder (PTSD) and PTG group according to the scores of PTSD Checklist Civilian Version and PTG Inventory survey. All participants received exposure to affective images. Electrocardiogram recording took place during the process for the purpose of analyzing HRV. Meanwhile, functional near-infrared spectroscopy (fNIRS) was used to measure DLPFC activity through hemodynamic response. Our results indicated that, while performing the negative and positive picture stimulating, PTG increased both in low and high frequency components of HRV compared with the control group, but PTSD was not observed in this phenomenon. Moreover, the fNIRS data revealed that PTG had an increased activation in the left DLPFC compared to the control in the condition of negative pictures stimulating, wheras PTSD showed a higher activation in the right DLPFC while receiving positive pictures stimulating. To our knowledge, this is the first study which provides the differences between PTSD and PTG in emotional regulation. PMID- 29192185 TI - Association of circulating progenitor cells with angiotensin II in newly diagnosed hypertensive patients. AB - Populations of CD34- and VEGFR2-expressing cells are responsible for regeneration of damaged endothelium and vascular remodelling. As their quantity and activity changes during cardiovascular diseases, they are potentially useful markers of cardiovascular health. The aim of our study was to investigate changes of various CD34+ and CD34+ VEGFR2+ populations in subjects with newly recognised hypertension and to evaluate whether observed alterations are influenced by clinical parameters and angiotensin II. Circulating CD34+ and CD34+ VEGFR2+ cells were analysed in peripheral blood samples by flow cytometry. Serum levels of angiotensin II were determined using immunoenzymatic assay. We discovered increased proportions of various CD34+ populations and CD34+ VEGFR2+ c-Kit+ cells in newly diagnosed patients. CD34+ cells seem to be influenced by angiotensin II, but we did not observe comparable results when populations co-expressing VEGFR2 were analysed. The quantity of CD34+ VEGFR2+ cells in patients with newly recognised primary hypertension ought to be determined by other factors. Increased proportions of CD34+ progenitors in blood could comprise compensatory mechanism for increased endothelial damage in hypertension. PMID- 29192187 TI - An Idealized Method of Simulating Residual Ionospheric Errors in Radio Occultation. AB - An idealized model is used to simulate radio occultation bending angles and residual ionospheric errors. The test results of the proposed simulation method agree with those of previous studies that use end-to-end simulation tools. Also, a new residual ionospheric error model proposed by Healy and Culverwell (2015) is verified in this letter by characterizing the key parameter, kappa. A simple model, kappa(a) = A - B * (a - 20)/60, is used to estimate the values of kappa, where A and B are constants that indicate the magnitude and variation of the values of kappa, respectively, and a represents the impact height. When the modelled values of kappa are applied in performing ionospheric corrections, the residual ionospheric errors decrease from approximately 5 * 10-8 rad to 1 * 10-9 rad at a latitude of 40 degrees N during the daytime and at a solar activity level of F10.7 = 210. Though the proposed model does not assess other error terms, such as those associated with asymmetry and noise, it will likely prove to be an effective tool for describing idealized residual ionospheric errors in radio occultation, and the features of the kappa values identified in this study may be helpful in improving ionospheric correction methods. PMID- 29192186 TI - Inverted activity patterns in ventromedial prefrontal cortex during value-guided decision-making in a less-is-more task. AB - Ventromedial prefrontal cortex has been linked to choice evaluation and decision making in humans but understanding the role it plays is complicated by the fact that little is known about the corresponding area of the macaque brain. We recorded activity in macaques using functional magnetic resonance imaging during two very different value-guided decision-making tasks. In both cases ventromedial prefrontal cortex activity reflected subjective choice values during decision making just as in humans but the relationship between the blood oxygen level dependent signal and both decision-making and choice value was inverted and opposite to the relationship seen in humans. In order to test whether the ventromedial prefrontal cortex activity related to choice values is important for decision-making we conducted an additional lesion experiment; lesions that included the same ventromedial prefrontal cortex region disrupted normal subjective evaluation of choices during decision-making. PMID- 29192188 TI - Transient experimental demonstration of an elliptical thermal camouflage device. AB - The camouflage phenomenon (invisibility or illusion) of thermodynamics has attracted great attentions and many experimental demonstrations have been achieved by virtue of simplified approaches or the scattering cancellation. However, all of the experiments conducted are limited in the invisibility of spheres or two-dimensional (2D) cylinders. An ellipsoid camouflage device with a homogenous and isotropic shell is firstly reported based on the idea of the neutral inclusion and a 2D elliptical thermal camouflage device is realized by a thin-layer cloak of homogeneous isotropic material firstly. The robustness of this scheme is validated in both 2D and 3D configurations. The current work may provide a new avenue to the control of the thermal signatures and we believe this work will broaden the current research and pave a new path to the control of the path of the heat transfer. PMID- 29192189 TI - Single-shot structural analysis by high-energy X-ray diffraction using an ultrashort all-optical source. AB - High-energy X-rays (HEX-rays) with photon energies on order of 100 keV have attractive characteristics, such as comparably low absorption, high spatial resolution and the ability to access inner-shell states of heavy atoms. These properties are advantageous for many applications ranging from studies of bulk materials to the investigation of materials in extreme conditions. Ultrafast X ray diffraction allows the direct imaging of atomic dynamics simultaneously on its natural time and length scale. However, using HEX-rays for ultrafast studies has been limited due to the lack of sources that can generate pulses of sufficiently short (femtosecond) duration in this wavelength range. Here we show single-crystal diffraction using ultrashort ~90 keV HEX-ray pulses generated by an all-optical source based on inverse Compton scattering. We also demonstrate a method for measuring the crystal lattice spacing in a single shot that contains only ~105 photons in a spectral bandwidth of ~50% full width at half maximum (FWHM). Our approach allows us to obtain structural information from the full X ray spectrum. As target we use a cylindrically bent Ge crystal in Laue transmission geometry. This experiment constitutes a first step towards measurements of ultrafast atomic dynamics using femtosecond HEX-ray pulses. PMID- 29192191 TI - Viscous Fingering in Multiport Hele Shaw Cell for Controlled Shaping of Fluids. AB - The pursuit of mimicking complex multiscale systems has been a tireless effort with many successes but a daunting task ahead. A new perspective to engineer complex cross-linked meshes and branched/tree-like structures at different scales is presented here. Control over Saffman-Taylor instability which otherwise randomly rearranges viscous fluid in a 'lifted Hele-Shaw cell' is proposed for the same. The proposed control employs multiple-ports or source-holes in this cell, to spontaneously shape a stretched fluid film into a network of well defined webs/meshes and ordered multiscale tree-like patterns. Use of multiple ports enables exercising strong control to fabricate such structures, in a robust and repeated fashion, which otherwise are completely non-characteristic to viscous fingering process. The proposed technique is capable of fabricating spontaneously families of wide variety of structures over micro and very large scale in a period of few seconds. Thus the proposed method forms a solid foundation to new pathways for engineering multiscale structures for several scientific applications including efficient gas exchange, heat transport, tissue engineering, organ-on-chip, and so on. Proposal of multi-port Hele-Shaw cell also opens new avenues for investigation of complex multiple finger interactions resulting in interesting fluid patterns. PMID- 29192190 TI - Schwann cell TRPA1 mediates neuroinflammation that sustains macrophage-dependent neuropathic pain in mice. AB - It is known that transient receptor potential ankyrin 1 (TRPA1) channels, expressed by nociceptors, contribute to neuropathic pain. Here we show that TRPA1 is also expressed in Schwann cells. We found that in mice with partial sciatic nerve ligation, TRPA1 silencing in nociceptors attenuated mechanical allodynia, without affecting macrophage infiltration and oxidative stress, whereas TRPA1 silencing in Schwann cells reduced both allodynia and neuroinflammation. Activation of Schwann cell TRPA1 evoked NADPH oxidase 1 (NOX1)-dependent H2O2 release, and silencing or blocking Schwann cell NOX1 attenuated nerve injury induced macrophage infiltration, oxidative stress and allodynia. Furthermore, the NOX2-dependent oxidative burst, produced by macrophages recruited to the perineural space activated the TRPA1-NOX1 pathway in Schwann cells, but not TRPA1 in nociceptors. Schwann cell TRPA1 generates a spatially constrained gradient of oxidative stress, which maintains macrophage infiltration to the injured nerve, and sends paracrine signals to activate TRPA1 of ensheathed nociceptors to sustain mechanical allodynia. PMID- 29192192 TI - Fruit fracture biomechanics and the release of Lepidium didymum pericarp-imposed mechanical dormancy by fungi. AB - The biomechanical and ecophysiological properties of plant seed/fruit structures are fundamental to survival in distinct environments. Dispersal of fruits with hard pericarps (fruit coats) encasing seeds has evolved many times independently within taxa that have seed dispersal as their default strategy. The mechanisms by which the constraint of a hard pericarp determines germination timing in response to the environment are currently unknown. Here, we show that the hard pericarp of Lepidium didymum controls germination solely by a biomechanical mechanism. Mechanical dormancy is conferred by preventing full phase-II water uptake of the encased non-dormant seed. The lignified endocarp has biomechanically and morphologically distinct regions that serve as predetermined breaking zones. This pericarp-imposed mechanical dormancy is released by the activity of common fungi, which weaken these zones by degrading non-lignified pericarp cells. We propose that the hard pericarp with this biomechanical mechanism contributed to the global distribution of this species in distinct environments. PMID- 29192193 TI - Alleviation of adverse effects of drought stress on wheat seed germination using atmospheric dielectric barrier discharge plasma treatment. AB - Atmospheric dielectric barrier discharge (DBD) was attempted to improve the resistance of wheat seed to drought stress. Effects of DBD plasma on wheat seed germination, seedling growth, osmotic-adjustment products, lipid peroxidation, reactive oxygen species (ROS), antioxidant enzyme activity, abscisic acid, and drought resistant related genes expression under drought stress were investigated. The changes of the wheat seed coat before and after the DBD plasma treatment were explored. Experimental results showed that the DBD plasma treatment could alleviate the adverse effects of drought stress on wheat seed germination and seedling growth; the germination potential and germination rate increased by 27.2% and 27.6%, and the root length and shoot length of the wheat seedlings also increased. Proline and soluble sugar levels under drought stress were improved after the DBD plasma treatment, whereas the malondialdehyde content decreased. ROS contents under drought stress were reduced after the DBD plasma treatment, whereas the activities of superoxide dismutase, catalase, and peroxidase were promoted. DBD plasma treatment promoted abscisic acid generation in wheat seedlings, and it also regulated functional gene LEA1 and stimulated regulation genes SnRK2 and P5CS to resist drought stress. Etching effect and surface modification occurred on the seed coat after the DBD plasma treatment. PMID- 29192194 TI - Solution structure and interaction with copper in vitro and in living cells of the first BIR domain of XIAP. AB - The X-chromosome linked inhibitor of apoptosis (XIAP) is a multidomain metalloprotein involved in caspase inhibition and in copper homeostasis. It contains three zinc-binding baculoviral IAP repeats (BIR) domains, which are responsible for caspase interaction. Recently, it has been suggested that the BIR domains can bind copper, however high resolution data on such interaction is missing. Here we characterize by NMR the structural properties of BIR1 in solution, and the effects of its interaction with copper both in vitro and in physiological environments. BIR1 is dimeric in solution, consistent with the X ray structure. Cysteine 12, located in the unfolded N-terminal region, has a remarkably low redox potential, and is prone to oxidation even in reducing physiological environments. Interaction of BIR1 with copper(II) results in the oxidation of cysteine 12, with the formation of either an intermolecular disulfide bond between two BIR1 molecules or a mixed disulfide bond with glutathione, whereas the zinc binding site is not affected by the interaction. PMID- 29192195 TI - Repellency of zerumbone identified in Cyperus rotundus rhizome and other constituents to Blattella germanica. AB - The compounds 1,8-cineole and zerumbone (ZER) from the Cyperus rotundus rhizome along with another 11 previously identified rhizome essential oil constituents and alpha-humulene, which lacks the only carbonyl group present in ZER, as well as binary mixtures of ZER and seven active compounds were tested for repellency to male B. germanica. The results were compared to N,N-diethyl-3-methylbenzamide (deet). In filter-paper choice tests, ZER was the most repellent compound, and alpha-humulene was ineffective, which indicates that the alpha,beta-unsaturated carbonyl group of ZER is a prerequisite component for repellency. At 81.5 MUg cm 2, enhanced repellency was produced by binary mixtures of ZER and 1,8-cineole, (+)-dihydrocarvone or (R)-(+)-limonene (70:30, 50:50 and 30:70 ratios by weight). These mixtures were very effective against male B. germanica within 24 h and were more repellent than a single compound or deet alone. The optimum ZER content was determined to be more than 50%. In Ebeling choice box tests at 652.4 MUg cm-2, these compounds and deet resulted in complete repellency to intact male B. germanica, while they exhibited 35-47% repellency to antennectomized male one. Mixtures formulated from the active constituents of the C. rotundus rhizome could be useful as potential repellents for controlling B. germanica. PMID- 29192196 TI - A robust cell culture system supporting the complete life cycle of hepatitis B virus. AB - The discovery of sodium taurocholate cotransporting polypeptide (NTCP) as the hepatitis B virus (HBV) receptor enabled researchers to create hepatoma cell lines susceptible to HBV infection. Infection in current systems, however, is inefficient and virus fails to spread. Infection efficiency is enhanced by treating cells with polyethylene glycol 8000 (PEG) during infection. However, this alone does not promote virus spread. Here we show that maintaining PEG in culture medium increases the rate of infection by at least one order of magnitude, and, most importantly, promotes virus spread. To demonstrate the utility of this system, we show that two interferon-stimulated genes (ISGs), ISG20 and tetherin, restrict HBV spread in NTCP-expressing hepatoma cells. Thus, this protocol can be easily applied to existing cell culture systems to study the complete HBV life cycle, including virus spread. PMID- 29192197 TI - Interaction of Synthetic Human SLURP-1 with the Nicotinic Acetylcholine Receptors. AB - Human SLURP-1 is a secreted protein of the Ly6/uPAR/three-finger neurotoxin family that co-localizes with nicotinic acetylcholine receptors (nAChRs) and modulates their functions. Conflicting biological activities of SLURP-1 at various nAChR subtypes have been based on heterologously produced SLURP-1 containing N- and/or C-terminal extensions. Here, we report the chemical synthesis of the 81 amino acid residue human SLURP-1 protein, characterization of its 3D structure by NMR, and its biological activity at nAChR subtypes. Radioligand assays indicated that synthetic SLURP-1 did not compete with [125I] alpha-bungarotoxin (alpha-Bgt) binding to human neuronal alpha7 and Torpedo californica muscle-type nAChRs, nor to mollusk acetylcholine binding proteins (AChBP). Inhibition of human alpha7-mediated currents only occurred in the presence of the allosteric modulator PNU120596. In contrast, we observed robust SLURP-1 mediated inhibition of human alpha3beta4, alpha4beta4, alpha3beta2 nAChRs, as well as human and rat alpha9alpha10 nAChRs. SLURP-1 inhibition of alpha9alpha10 nAChRs was accentuated at higher ACh concentrations, indicating an allosteric binding mechanism. Our results are discussed in the context of recent studies on heterologously produced SLURP-1 and indicate that N-terminal extensions of SLURP-1 may affect its activity and selectivity on its targets. In this respect, synthetic SLURP-1 appears to be a better probe for structure function studies. PMID- 29192198 TI - Hydrodenitrogenation of pyridines and quinolines at a multinuclear titanium hydride framework. AB - Investigation of the hydrodenitrogenation (HDN) of aromatic N-heterocycles such as pyridines and quinolines at the molecular level is of fundamental interest and practical importance, as this transformation is essential in the industrial petroleum refining on solid catalysts. Here, we report the HDN of pyridines and quinolines by a molecular trinuclear titanium polyhydride complex. Experimental and computational studies reveal that the denitrogenation of a pyridine or quinoline ring is easier than the ring-opening reaction at the trinuclear titanium hydride framework, which is in sharp contrast with what has been reported previously. Hydrolysis of the pyridine-derived nitrogen-free hydrocarbon skeleton at the titanium framework with H2O leads to recyclization to afford cyclopentadiene with the generation of ammonia, while treatment with HCl gives the corresponding linear hydrocarbon products and ammonium chloride. This work has provides insights into the mechanistic aspects of the hydrodenitrogenation of an aromatic N-heterocycle at the molecular level. PMID- 29192199 TI - CRISPR/Cas9-assisted gRNA-free one-step genome editing with no sequence limitations and improved targeting efficiency. AB - The CRISPR/Cas9 system is a powerful, revolutionary tool for genome editing. However, it is not without limitations. There are PAM-free and CRISPR-tolerant regions that cannot be modified by the standard CRISPR/Cas9 system, and off target activity impedes its broader applications. To avoid these drawbacks, we developed a very simple CRISPR/Cas9-assisted gRNA-free one-step (CAGO) genome editing technique which does not require the construction of a plasmid to express a specific gRNA. Instead, a universal N20 sequence with a very high targeting efficiency is inserted into the E. coli chromosome by homologous recombination, which in turn undergoes a double-stranded break by CRISPR/Cas9 and induces an intra-chromosomal recombination event to accomplish the editing process. This technique was shown to be able to edit PAM-free and CRISPR-tolerant regions with no off-target effects in Escherichia coli. When applied to multi-locus editing, CAGO was able to modify one locus in two days with a near 100% editing efficiency. Furthermore, modified CAGO was used to edit large regions of up to 100 kbp with at least 75% efficiency. Finally, genome editing by CAGO only requires a transformation procedure and the construction of a linear donor DNA cassette, which was further simplified by applying a modular design strategy. Although the technique was established in E. coli, it should be applicable to other organisms with only minor modifications. PMID- 29192200 TI - CRISPR/Cas9-mediated genome editing in naive human embryonic stem cells. AB - The combination of genome-edited human embryonic stem cells (hESCs) and subsequent neural differentiation is a powerful tool to study neurodevelopmental disorders. Since the naive state of pluripotency has favourable characteristics for efficient genome-editing, we optimized a workflow for the CRISPR/Cas9 system in these naive stem cells. Editing efficiencies of respectively 1.3-8.4% and 3.8 19% were generated with the Cas9 nuclease and the D10A Cas9 nickase mutant. Next to this, wildtype and genome-edited naive hESCs were successfully differentiated to neural progenitor cells. As a proof-of-principle of our workflow, two monoclonal genome-edited naive hESCs colonies were obtained for TUNA, a long non coding RNA involved in pluripotency and neural differentiation. In these genome edited hESCs, an effect was seen on expression of TUNA, although not on neural differentiation potential. In conclusion, we optimized a genome-editing workflow in naive hESCs that can be used to study candidate genes involved in neural differentiation and/or functioning. PMID- 29192201 TI - Mechanism in External Field-mediated Trapping of Bacteria Sensitive to Nanoscale Surface Chemical Structure. AB - Molecular imprinting technique enables the selective binding of nanoscale target molecules to a polymer film, within which their chemical structure is transcribed. Here, we report the successful production of mixed bacterial imprinted film (BIF) from several food poisoning bacteria by the simultaneous imprinting of their nanoscale surface chemical structures (SCS), and provide highly selective trapping of original micron-scale bacteria used in the production process of mixed BIF even for multiple kinds of bacteria in real samples. Particularly, we reveal the rapid specific identification of E. coli group serotypes (O157:H7 and O26:H11) using an alternating electric field and a quartz crystal microbalance. Furthermore, we have performed the detailed physicochemical analysis of the specific binding of SCS and molecular recognition sites (MRS) based on the dynamic Monte Carlo method under taking into account the electromagnetic interaction. The dielectrophoretic selective trapping greatly depends on change in SCS of bacteria damaged by thermal treatment, ultraviolet irradiation, or antibiotic drugs, which can be well explained by the simulation results. Our results open the avenue for an innovative means of specific and rapid detection of unknown bacteria for food safety and medicine from a nanoscale viewpoint. PMID- 29192202 TI - Reassessment of fluctuating dental asymmetry in Down syndrome. AB - Fluctuating dental asymmetry (FDA) is a tool to measure developmental stability that could be increased in gonosomal aneuploidies. The aim of this study was to quantify FDA in individuals with Down syndrome (DS). The study group comprised 40 individuals with DS, and a control group matched for age and sex was created. The target teeth were the maxillary central incisors (11,21), maxillary lateral incisors (12,22), maxillary canines (13,23), and maxillary first molars (16,26). Dental morphometric variables measured on CBCT images included tooth length, crown height, root length, mesio-distal diameter, crown-to-root ratio, vestibular palatine diameter, mid mesio-distal diameter, mid buccal-palatal diameter, maximum buccal-palatal diameter, and cervical circumference. The FA2 fluctuating asymmetry index (Palmer and Strobeck, 1986) was applied. Some discrepancies in crown-to-root ratios and root length asymmetry were significantly lower in the DS individuals than in controls. Combining the crown-to-root ratio of tooth 11 versus 21, tooth 12 versus 22, and tooth 13 versus 23, we developed a predictive model with a discriminatory power between DS and controls of 0.983. Some dental morphometric variables may actually be more stable in DS individuals than in the general population. This offers a new perspective on the relationship between canalization, fluctuating asymmetry, and aneuploidy. PMID- 29192203 TI - Habitat-dependent changes in vigilance behaviour of Red-crowned Crane influenced by wildlife tourism. AB - The Endangered Red-crowned Crane (Grus japonensis) is one of the most culturally iconic and sought-after species by wildlife tourists. Here we investigate how the presence of tourists influence the vigilance behaviour of cranes foraging in Suaeda salsa salt marshes and S. salsa/Phragmites australis mosaic habitat in the Yellow River Delta, China. We found that both the frequency and duration of crane vigilance significantly increased in the presence of wildlife tourists. Increased frequency in crane vigilance only occurred in the much taller S. salsa/P. australis mosaic vegetation whereas the duration of vigilance showed no significant difference between the two habitats. Crane vigilance declined with increasing distance from wildlife tourists in the two habitats, with a minimum distance of disturbance triggering a high degree of vigilance by cranes identified at 300 m. The presence of wildlife tourists may represent a form of disturbance to foraging cranes but is habitat dependent. Taller P. australis vegetation serves primarily as a visual obstruction for cranes, causing them to increase the frequency of vigilance behaviour. Our findings have important implications for the conservation of the migratory red-crowned crane population that winters in the Yellow River Delta and can help inform visitor management. PMID- 29192204 TI - Bending and breaking of stripes in a charge ordered manganite. AB - In charge-ordered phases, broken translational symmetry emerges from couplings between charge, spin, lattice, or orbital degrees of freedom, giving rise to remarkable phenomena such as colossal magnetoresistance and metal-insulator transitions. The role of the lattice in charge-ordered states remains particularly enigmatic, soliciting characterization of the microscopic lattice behavior. Here we directly map picometer scale periodic lattice displacements at individual atomic columns in the room temperature charge-ordered manganite Bi0.35Sr0.18Ca0.47MnO3 using aberration-corrected scanning transmission electron microscopy. We measure transverse, displacive lattice modulations of the cations, distinct from existing manganite charge-order models. We reveal locally unidirectional striped domains as small as ~5 nm, despite apparent bidirectionality over larger length scales. Further, we observe a direct link between disorder in one lattice modulation, in the form of dislocations and shear deformations, and nascent order in the perpendicular modulation. By examining the defects and symmetries of periodic lattice displacements near the charge ordering phase transition, we directly visualize the local competition underpinning spatial heterogeneity in a complex oxide.

PMID- 29192206 TI - Developmental YAPdeltaC determines adult pathology in a model of spinocerebellar ataxia type 1. AB - YAP and its neuronal isoform YAPdeltaC are implicated in various cellular functions. We found that expression of YAPdeltaC during development, but not adulthood, rescued neurodegeneration phenotypes of mutant ataxin-1 knock-in (Atxn1-KI) mice. YAP/YAPdeltaC interacted with RORalpha via the second WW domain and served as co-activators of its transcriptional activity. YAP/YAPdeltaC formed a transcriptional complex with RORalpha on cis-elements of target genes and regulated their expression. Both normal and mutant Atxn1 interacted with YAP/YAPdeltaC, but only mutant Atxn1 depleted YAP/YAPdeltaC from the RORalpha complex to suppress transcription on short timescales. Over longer periods, mutant Atxn1 also decreased RORalpha in vivo. Genetic supplementation of YAPdeltaC restored the RORalpha and YAP/YAPdeltaC levels, recovered YAP/YAPdeltaC in the RORalpha complex and normalized target gene transcription in Atxn1-KI mice in vivo. Collectively, our data suggest that functional impairment of YAP/YAPdeltaC by mutant Atxn1 during development determines the adult pathology of SCA1 by suppressing RORalpha-mediated transcription. PMID- 29192207 TI - Discovery of naturally occurring ESR1 mutations in breast cancer cell lines modelling endocrine resistance. AB - Resistance to endocrine therapy remains a major clinical problem in breast cancer. Genetic studies highlight the potential role of estrogen receptor-alpha (ESR1) mutations, which show increased prevalence in the metastatic, endocrine resistant setting. No naturally occurring ESR1 mutations have been reported in in vitro models of BC either before or after the acquisition of endocrine resistance making functional consequences difficult to study. We report the first discovery of naturally occurring ESR1 Y537C and ESR1 Y537S mutations in MCF7 and SUM44 ESR1 positive cell lines after acquisition of resistance to long-term-estrogen deprivation (LTED) and subsequent resistance to fulvestrant (ICIR). Mutations were enriched with time, impacted on ESR1 binding to the genome and altered the ESR1 interactome. The results highlight the importance and functional consequence of these mutations and provide an important resource for studying endocrine resistance. PMID- 29192208 TI - Endogenous Annexin-A1 Regulates Haematopoietic Stem Cell Mobilisation and Inflammatory Response Post Myocardial Infarction in Mice In Vivo. AB - Endogenous anti-inflammatory annexin-A1 (ANX-A1) plays an important role in preserving left ventricular (LV) viability and function after ischaemic insults in vitro, but its long-term cardioprotective actions in vivo are largely unknown. We tested the hypothesis that ANX-A1-deficiency exaggerates inflammation, haematopoietic stem progenitor cell (HSPC) activity and LV remodelling in response to myocardial ischaemia in vivo. Adult ANX - A1 -/- mice subjected to coronary artery occlusion exhibited increased infarct size and LV macrophage content after 24-48 h reperfusion compared with wildtype (WT) counterparts. In addition, ANX - A1 -/- mice exhibited greater expansion of HSPCs and altered pattern of HSPC mobilisation 8 days post-myocardial infarction, with increased circulating neutrophils and platelets, consistent with increased cardiac inflammation as a result of increased myeloid invading injured myocardium in response to MI. Furthermore, ANX - A1 -/- mice exhibited significantly increased expression of LV pro-inflammatory and pro-fibrotic genes and collagen deposition after MI compared to WT counterparts. ANX-A1-deficiency increased cardiac necrosis, inflammation, hypertrophy and fibrosis following MI, accompanied by exaggerated HSPC activity and impaired macrophage phenotype. These findings suggest that endogenous ANX-A1 regulates mobilisation and differentiation of HSPCs. Limiting excessive monocyte/neutrophil production may limit LV damage in vivo. Our findings support further development of novel ANX-A1-based therapies to improve cardiac outcomes after MI. PMID- 29192209 TI - Mineral particles stimulate innate immunity through neutrophil extracellular traps containing HMGB1. AB - Calcium phosphate-based mineralo-organic particles form spontaneously in the body and may represent precursors of ectopic calcification. We have shown earlier that these particles induce activation of caspase-1 and secretion of IL-1beta by macrophages. However, whether the particles may produce other effects on immune cells is unclear. Here, we show that these particles induce the release of neutrophil extracellular traps (NETs) in a size-dependent manner by human neutrophils. Intracellular production of reactive oxygen species is required for particle-induced NET release by neutrophils. NETs contain the high-mobility group protein B1 (HMGB1), a DNA-binding protein capable of inducing secretion of TNF alpha by a monocyte/macrophage cell line and primary macrophages. HMGB1 functions as a ligand of Toll-like receptors 2 and 4 on macrophages, leading to activation of the MyD88 pathway and TNF-alpha production. Furthermore, HMGB1 is critical to activate the particle-induced pro-inflammatory cascade in the peritoneum of mice. These results indicate that mineral particles promote pro-inflammatory responses by engaging neutrophils and macrophages via signaling of danger signals through NETs. PMID- 29192210 TI - Low resistance to chytridiomycosis in direct-developing amphibians. AB - Host-generalist pathogens sporadically infect naive hosts, potentially triggering epizootics. The waterborne fungus Batrachochytrium dendrobatidis (Bd) is linked to declines of hundreds of amphibian species with aquatic larvae. Although several population declines and extinctions attributed to Bd have been reported among cryptic species undergoing direct development away from water, epidemiological studies focused on these terrestrial frogs are lacking. Our field data support that terrestrial direct-developing hosts are less exposed to Bd during their ontogeny than species with aquatic larvae, and thus they might lack adaptive responses against waterborne chytrids. Using controlled laboratory experiments, we exposed wild-caught amphibian species with terrestrial and aquatic life histories to Bd and found that direct developers showed more rapid increases in infection loads and experienced higher mortality rates than species with aquatic larvae. Our findings provide novel information about host responses to generalist pathogens and specifically show that our focal direct developing species have low resistance to Bd infections. Finally, our results underscore that we should not ignore Bd as a potential threat to direct developing species simply because they are less exposed to Bd in nature; instead future amphibian conservation plans should include efforts to safeguard hundreds of direct developing amphibian species globally. PMID- 29192211 TI - Nematic superconducting state in iron pnictide superconductors. AB - Nematic order often breaks the tetragonal symmetry of iron-based superconductors. It arises from regular structural transition or electronic instability in the normal phase. Here, we report the observation of a nematic superconducting state, by measuring the angular dependence of the in-plane and out-of-plane magnetoresistivity of Ba0.5K0.5Fe2As2 single crystals. We find large twofold oscillations in the vicinity of the superconducting transition, when the direction of applied magnetic field is rotated within the basal plane. To avoid the influences from sample geometry or current flow direction, the sample was designed as Corbino-shape for in-plane and mesa-shape for out-of-plane measurements. Theoretical analysis shows that the nematic superconductivity arises from the weak mixture of the quasi-degenerate s-wave and d-wave components of the superconducting condensate, most probably induced by a weak anisotropy of stresses inherent to single crystals.

AB - We present a simple and practical strategy that allows to design high-efficiency grating couplers. The technique is based on the simultaneous apodization of two structural parameters: the grating period and the fill-factor, along with the optimization of the grating coupler etching depth. Considering a 260 nm Si-thick Silicon-on-insulator platform, we numerically demonstrated a coupling efficiency of -0.8 dB (83%), well matching the experimental value of -0.9 dB (81%). Thanks to the optimized design, these results represent the best performance ever reported in the literature for SOI structures without the use of any back reflector. PMID- 29192213 TI - Differentiation therapy revisited. AB - The concept of differentiation therapy emerged from the fact that hormones or cytokines may promote differentiation ex vivo, thereby irreversibly changing the phenotype of cancer cells. Its hallmark success has been the treatment of acute promyelocytic leukaemia (APL), a condition that is now highly curable by the combination of retinoic acid (RA) and arsenic. Recently, drugs that trigger differentiation in a variety of primary tumour cells have been identified, suggesting that they are clinically useful. This Opinion article analyses the basis for the clinical successes of RA or arsenic in APL by assessing the respective roles of terminal maturation and loss of self-renewal. By reviewing other successful examples of drug-induced tumour cell differentiation, novel approaches to transform differentiating drugs into more efficient therapies are proposed. PMID- 29192214 TI - Ribosome biogenesis in cancer: new players and therapeutic avenues. AB - The ribosome is a complex molecular machine composed of numerous distinct proteins and nucleic acids and is responsible for protein synthesis in every living cell. Ribosome biogenesis is one of the most multifaceted and energy- demanding processes in biology, involving a large number of assembly and maturation factors, the functions of which are orchestrated by multiple cellular inputs, including mitogenic signals and nutrient availability. Although causal associations between inherited mutations affecting ribosome biogenesis and elevated cancer risk have been established over the past decade, mechanistic data have emerged suggesting a broader role for dysregulated ribosome biogenesis in the development and progression of most spontaneous cancers. In this Opinion article, we highlight the most recent findings that provide new insights into the molecular basis of ribosome biogenesis in cancer and offer our perspective on how these observations present opportunities for the design of new targeted cancer treatments. PMID- 29192217 TI - Decreased miRNA expression in Klinefelter syndrome. AB - The widelyvariable phenotypic spectrum and the different severity of symptoms in men with Klinefelter syndrome (KS) suggest a role for epigenetic mediators. Therefore, the aim of this study is to evaluate the possible involvement of miRNAs in the clinical manifestations of KS. To accomplish this, we performed a transcriptome analysis in peripheral blood mononuclear cells (PBMCs) of 10 non mosaic KS patients, 10 aged-matched healthy men and 10 aged-matched healthy female controls with normal karyotype. After RNA extraction from PBMC and the preparation of RNA libraries, the samples were sequenced using next generation high-throughput sequencing technology. Expression profiling analysis revealed a significant differential expression of 2 miRNAs in KS compared to male controls. In particular, MIR3648 resulted significantly (q-value < 0.0001) down-regulated by -19.084- fold, while MIR3687was strongly down-regulated (q-value < 0.0001) considering KS patients. These results were confirmed by qRT-PCR. The functional analysis of the two transcripts showed that they seem to play a role in breast cancer, hemopoietic abnormalities, immune defects and adipocyte differentiation and fat cell maturation. Therefore, we speculate that both miRNAs may play a role in the immune and metabolic disorders and in the risk of breast cancer development in men with KS. PMID- 29192216 TI - BET inhibitors RVX-208 and PFI-1 reactivate HIV-1 from latency. AB - Persistent latent reservoir in resting CD4+ T cells is a major obstacle in curing HIV-1 infection. Effective strategies for eradication of the HIV-1 reservoir are urgently needed. We report here for the first time that two BET inhibitors, RVX 208, which has entered phase II clinical trials for diverse cardiovascular disorders, and PFI-1, which has been widely studied in oncology, can reactivate HIV-1 from latency. RVX-208 and PFI-1 treatment alone or in combination with other latency reversing agents efficiently reactivated HIV-1 transcription through an up-regulation of P-TEFb by increasing CDK9 Thr-186 phosphorylation in latently infected Jurkat T cells in vitro. The two BET inhibitors also reactivated HIV-1 transcription in cART treated patient-derived resting CD4+ T cells ex vivo, without influence on global immune cell activation. Our findings, in combination with previous reports, further confirm that BET inhibitors are a group of leading compounds for combating HIV-1 latency for viral eradication. PMID- 29192218 TI - Magnesium uptake by connecting fluid-phase endocytosis to an intracellular inorganic cation filter. AB - Cells acquire free metals through plasma membrane transporters. But, in natural settings, sequestering agents often render metals inaccessible to transporters, limiting metal bioavailability. Here we identify a pathway for metal acquisition, allowing cells to cope with this situation. Under limited bioavailability of Mg2+, yeast cells upregulate fluid-phase endocytosis and transfer solutes from the environment into their vacuole, an acidocalcisome-like compartment loaded with highly concentrated polyphosphate. We propose that this anionic inorganic polymer, which is an avid chelator of Mg2+, serves as an immobilized cation filter that accumulates Mg2+ inside these organelles. It thus allows the vacuolar exporter Mnr2 to efficiently transfer Mg2+ into the cytosol. Leishmania parasites also employ acidocalcisomal polyphosphate to multiply in their Mg2+-limited habitat, the phagolysosomes of inflammatory macrophages. This suggests that the pathway for metal uptake via endocytosis, acidocalcisomal polyphosphates and export into the cytosol, which we term EAPEC, is conserved. PMID- 29192220 TI - Study of the lithium diffusion properties and high rate performance of TiNb6O17 as an anode in lithium secondary battery. AB - TiNb6O17 and TiNb2O7 were synthesized using a solid-state method. The techniques were used to assess the electrochemical performance and lithium diffusion kinetics of TiNb6O17 related to the unit cell volume with TiNb2O7. The charge discharge curves and cyclic voltammetry revealed TiNb6O17 to have a similar redox potential to TiNb2O7 as well as a high discharge capacity. The rate performance of TiNb6O17 was measured using a rate capability test. SSCV and EIS showed that TiNb6O17 had higher lithium diffusion coefficients during the charging. From GITT, the lithium diffusion coefficients at the phase transition region showed the largest increase from TiNb2O7 to TiNb6O17. PMID- 29192219 TI - Symbionts protect aphids from parasitic wasps by attenuating herbivore-induced plant volatiles. AB - Plants respond to insect attack by releasing blends of volatile chemicals that attract their herbivores' specific natural enemies, while insect herbivores may carry endosymbiotic microorganisms that directly improve herbivore survival after natural enemy attack. Here we demonstrate that the two phenomena can be linked. Plants fed upon by pea aphids release volatiles that attract parasitic wasps, and the pea aphid can carry facultative endosymbiotic bacteria that prevent the development of the parasitic wasp larva and thus markedly improve aphid survival after wasp attack. We show that these endosymbionts also attenuate the systemic release of volatiles by plants after aphid attack, reducing parasitic wasp recruitment and increasing aphid fitness. Our results reveal a novel mechanism through which symbionts can benefit their hosts and emphasise the importance of considering the microbiome in understanding insect ecological interactions. PMID- 29192221 TI - A combined experimental and theoretical investigation on cellular blebbing. AB - Although accumulating evidence has demonstrated the important role of membrane blebbing in various cellular processes, the fundamental question of how the initiation/evolution of blebs are influenced by physical factors like membrane cortex interactions and intracellular pressure remains unclear. Here, we report a combined modeling and experimental study to address this outstanding issue. Specifically, boundary integral method was used to track the motion of membrane (in 3D) during blebbing while possible rupture of the bilayer-cortex adhesion has also been taken into account. We showed that, for a given differential pressure across the cell membrane, the size of the weakened cortex must be over a critical value for blebbing to occur and the steady-state volume of a bleb is proportional to its initial growth rate, all in good agreement with recent experiments. The predicted shape evolution of blebs also matches well with our observations. Finally, a blebbing map, summarizing the essential physics involved, was obtained which exhibits three distinct regimes: no bleb formation corresponding to a low intracellular pressure or a small weakened cortex region; bleb formed with a fixed width when the disrupted cortex zone is very large; and a growing bleb resulted from progressive membrane-cortex detachment under intermediate weakened cortex size. PMID- 29192222 TI - Roller-Induced Bundling of Long Silver Nanowire Networks for Strong Interfacial Adhesion, Highly Flexible, Transparent Conductive Electrodes. AB - Silver nanowires (AgNWs) have been the most promising electrode materials for fabrication of flexible transparent touch panel, displays and many other electronics because of their excellent electrical properties, cost effectiveness, synthesis scalability, and suitability for mass production. Although a few literature reports have described the use of short Ag NWs in fabrication of randomly oriented Ag NW network-based electrode, their electrical conductivities are still far lower than that of Ag films. So far, no any literature report was able to provide any simple solution to fabrication of large-area and mass manufactural ability to address the issues, such as, conductivity, transparency, electrical current withstand, bending stability, and interfacial adhesion. In the current work, we provide a simple solution to conquer the above-mentioned challenges, and report the development of long Ag NW bundle network electrodes on large area PET films that were coated, aligned, and bundled quickly and simply using a steel roller. Our developed AgNWs-bundle networks had superior performance in optoelectronic properties (sheet resistance 5.8 Omega sq-1; optical transmittance 89% at 550 nm wavelength), electrical current withstand up to 500 mA, and bending stability over 5000 bending cycles, and strong interfacial adhesion. PMID- 29192223 TI - Predictors of Atrial Fibrillation Recurrence after Catheter Ablation: Data from the German Ablation Registry. AB - Catheter ablation (CA) for atrial fibrillation (AF) has emerged as a widespread first or second line treatment option. However, up to 45% of patients (pts) show recurrence of AF within 12 month after CA. We present prospective multicenter registry data comparing characteristics of pts with and without recurrence of AF within the first year after CA. This study comprises all pts with complete follow up one year after CA (1-y-FU; n = 3679). During 1y-FU in 1687 (45.9%) pts recurrence of AF occurred. The multivariate analysis revealed female sex and AF type prior to the procedure as predictors for AF recurrence. Furthermore, comorbidities such as valvular heart disease and renal failure as well as an early AF relapse were also predictors of AF recurrence during 1-y-FU. However, despite an AF recurrence rate of 45.9%, the majority of these pts (72.4%) reported a significant alleviation of clinical symptoms. In conclusion in pts with initially successful CA for AF female sex, AF type, in-hospital AF relapse and comorbidities such as renal failure and valvular heart disease are independent predictors for AF recurrence during 1-y-FU. However, the majority of pts deemed their interventions as successful with significant reduction of symptoms irrespective of AF. PMID- 29192224 TI - Conserved RNA structures in the intergenic regions of ambisense viruses. AB - Ambisense viruses are negative-sense single-stranded RNA viruses that use a unique expression strategy. Their genome contains at least one ambisense RNA segment that carries two oppositely oriented reading frames separated by an intergenic region. It is believed that a structural RNA element within the intergenic region is involved in transcription termination. However, a general overview over the structural repertoire of ambisense intergenic regions is currently lacking. In this study we investigated the structural potential of the intergenic regions of all known ambisense viruses and compared their structural repertoire by structure-guided clustering. Intergenic regions of most ambisense viruses possess a high potential to build stable secondary structures and many viruses share common structural motifs in the intergenic regions of their ambisense segments. We demonstrate that (i) within the phylogenetic virus groups sets of conserved functional structures are present, but that (ii) between the groups conservation is low to non-existent. These results reflect a high degree of freedom to regulate ambisense transcription termination and also imply that the genetic strategy of having an ambisense RNA genome has evolved several times independently. PMID- 29192225 TI - Tunneling nanotubes (TNT) mediate long-range gap junctional communication: Implications for HIV cell to cell spread. AB - Cell-to-cell communication is essen for the development of multicellular systems and is coordinated by soluble factors, exosomes, gap junction (GJ) channels, and the recently described tunneling nanotubes (TNTs). We and others have demonstrated that TNT-like structures are mostly present during pathogenic conditions, including HIV infection. However, the nature, function, and communication properties of TNTs are still poorly understood. In this manuscript, we demonstrate that TNTs induced by HIV infection have functional GJs at the ends of their membrane extensions and that TNTs mediate long-range GJ communication during HIV infection. Blocking or reducing GJ communication during HIV infection resulted in aberrant TNT cell-to-cell contact, compromising HIV spread and replication. Thus, TNTs and associated GJs are required for the efficient cell-to cell communication and viral spread. Our data indicate that targeting TNTs/GJs may provide new therapeutic opportunities for the treatment of HIV. PMID- 29192226 TI - Transcriptomics reveal an integrative role for maternal thyroid hormones during zebrafish embryogenesis. AB - Thyroid hormones (THs) are essential for embryonic brain development but the genetic mechanisms involved in the action of maternal THs (MTHs) are still largely unknown. As the basis for understanding the underlying genetic mechanisms of MTHs regulation we used an established zebrafish monocarboxylic acid transporter 8 (MCT8) knock-down model and characterised the transcriptome in 25hpf zebrafish embryos. Subsequent mapping of differentially expressed genes using Reactome pathway analysis together with in situ expression analysis and immunohistochemistry revealed the genetic networks and cells under MTHs regulation during zebrafish embryogenesis. We found 4,343 differentially expressed genes and the Reactome pathway analysis revealed that TH is involved in 1681 of these pathways. MTHs regulated the expression of core developmental pathways, such as NOTCH and WNT in a cell specific context. The cellular distribution of neural MTH-target genes demonstrated their cell specific action on neural stem cells and differentiated neuron classes. Taken together our data show that MTHs have a role in zebrafish neurogenesis and suggest they may be involved in cross talk between key pathways in neural development. Given that the observed MCT8 zebrafish knockdown phenotype resembles the symptoms in human patients with Allan-Herndon-Dudley syndrome our data open a window into understanding the genetics of this human congenital condition. PMID- 29192228 TI - Inhibition of litter decomposition of two emergent macrophytes by addition of aromatic plant powder. AB - Aromatic plants show antimicrobial activity due to their essential oils, but their effect on litter decomposition is unclear. In this study, we evaluated the biomass loss and nutrient dynamics in leaf litters of two macrophytes (Miscanthus sacchariflorus and Carex brevicuspis) with and without addition of powdered material of the aromatic plant Polygonum hydropiper or the non-aromatic plant C. brevicuspis. The two powders had similar basic chemical qualities but P. hydropiperi had a higher essential oils concentration. Leaf litters of M. sacchariflorus and C. brevicuspis were incubated with powdered P. hydropiper or C. brevicuspis (500 g m-3, 250 g m-3, and no addition) for 120 days in a mesocosm experiment. Compared with the control (no addition), P. hydropiperi addition decelerated nutrient release and litter decomposition, while C. brevicuspis addition accelerated those processes. The nitrogen concentrations in both leaf litters and the phosphorus concentration in C. brevicuspis leaf litter were increased by addition of both plant powders. The fungal biomass in both leaf litters decreased after P. hydropiperi addition, due to the antifungal activity of its essential oils. These data indicate that the aromatic plant P. hydropiperi inhibits litter decomposition via its essential oils and that such inhibition is not species-specific. PMID- 29192229 TI - Seasonal Expression of Oxytocin and Oxytocin Receptor in the Scented Gland of Male Muskrat (Ondatra zibethicus). AB - Oxytocin (OT) can modulate multiple physiological functions via binding to the widely distributed oxytocin receptor (OTR). In this study, we investigated the seasonal expressions of OT, OTR and extracellular signal regulated kinase (ERK1/2) signaling pathway components in the scented gland of muskrat during the breeding and non-breeding seasons. Histologically, glandular cells, interstitial cells and excretory tubules were identified in the breeding season scented glands, whereas epithelial cells were sparse in the non-breeding season. Immunohistochemical results showed that OTR was present in epithelial cells and interstitial cells while OT, pERK1/2, ERK1/2 and c-fos were expressed in epithelial cells and glandular cells. The protein and mRNA expressions of OTR, OT and c-fos were significantly higher in the scented gland in the breeding season than in the non-breeding season. Importantly, the levels of OT in scented glands and serum were measured by hormone assays, and their concentrations were both significantly higher in the breeding season than in the non-breeding season. Moreover, bioinformatics analysis showed that the predicted targets of the differentially expressed microRNAs might include the genes encoding OTR, ERK1/2 and c-fos. These findings suggested that OT may regulate the function of muskrat scented glands by the locally expressed receptors. PMID- 29192227 TI - Conservation of Nonsense-Mediated mRNA Decay Complex Components Throughout Eukaryotic Evolution. AB - Nonsense-mediated mRNA decay (NMD) is an essential eukaryotic process regulating transcript quality and abundance, and is involved in diverse processes including brain development and plant defenses. Although some of the NMD machinery is conserved between kingdoms, little is known about its evolution. Phosphorylation of the core NMD component UPF1 is critical for NMD and is regulated in mammals by the SURF complex (UPF1, SMG1 kinase, SMG8, SMG9 and eukaryotic release factors). However, since SMG1 is reportedly missing from the genomes of fungi and the plant Arabidopsis thaliana, it remains unclear how UPF1 is activated outside the metazoa. We used comparative genomics to determine the conservation of the NMD pathway across eukaryotic evolution. We show that SURF components are present in all major eukaryotic lineages, including fungi, suggesting that in addition to UPF1 and SMG1, SMG8 and SMG9 also existed in the last eukaryotic common ancestor, 1.8 billion years ago. However, despite the ancient origins of the SURF complex, we also found that SURF factors have been independently lost across the Eukarya, pointing to genetic buffering within the essential NMD pathway. We infer an ancient role for SURF in regulating UPF1, and the intriguing possibility of undiscovered NMD regulatory pathways. PMID- 29192230 TI - Multi-scale magnetic mapping of serpentinite carbonation. AB - Peridotite carbonation represents a critical step within the long-term carbon cycle by sequestering volatile CO2 in solid carbonate. This has been proposed as one potential pathway to mitigate the effects of greenhouse gas release. Most of our current understanding of reaction mechanisms is based on hand specimen and laboratory-scale analyses. Linking laboratory-scale observations to field scale processes remains challenging. Here we present the first geophysical characterization of serpentinite carbonation across scales ranging from km to sub mm by combining aeromagnetic observations, outcrop- and thin section-scale magnetic mapping. At all scales, magnetic anomalies coherently change across reaction fronts separating assemblages indicative of incipient, intermittent, and final reaction progress. The abundance of magnetic minerals correlates with reaction progress, causing amplitude and wavelength variations in associated magnetic anomalies. This correlation represents a foundation for characterizing the extent and degree of in situ ultramafic rock carbonation in space and time. PMID- 29192231 TI - Regulation of ethylene-responsive SlWRKYs involved in color change during tomato fruit ripening. AB - WRKY transcription factors (TFs) play important roles in stress responses in planta. However, the function of WRKY TFs in the regulation of fruit ripening is unclear. Here, 23 tomato SlWRKYs that are similar to ethylene-responsive WRKY genes from other plant species, or show up-regulation during fruit ripening in previous genome-wide study, were selected, and their function in fruit ripening was investigated. Twelve SlWRKYs were found to be responsive to ethylene (SlER WRKYs), showing expression patterns similar to those of genes related to fruit ripening. Eight SlER-WRKYs-SlWRKY16, 17, 22, 25, 31, 33, 53, and 54, detected in the nuclei-interacted with and activated the promoters of 4 genes related to color change: Pheophytin Pheophorbide Hydrolase (SlPPH), Pheophorbide a Oxygenase (SlPAO), Phytoene Synthase 1 (SlPSY1) and Phytoene Desaturase (SlPDS). Yeast two hybrid and bimolecular fluorescence complement (BiFC) assays in Arabidopsis protoplasts indicated that protein interactions occurred between SlWRKY17 and SlRIN, SlERF2b or SlERF7; SlWRKY33 and SlERF7; SlWRKY54 and SlERF2b; and SlWRKY16 and SlWRKY17. Suppression of SlWRKY 16, 17, 53 or 54 by virus-induced gene silencing (VIGS) retarded the red coloration of the fruit. Our study provides comprehensive molecular evidence that WRKY TFs function in fruit ripening, particularly in color change, and are linked to the intricate regulatory network of other ripening regulators. PMID- 29192232 TI - Thin single crystal perovskite solar cells to harvest below-bandgap light absorption. AB - The efficiency of perovskite solar cells has surged in the past few years, while the bandgaps of current perovskite materials for record efficiencies are much larger than the optimal value, which makes the efficiency far lower than the Shockley-Queisser efficiency limit. Here we show that utilizing the below-bandgap absorption of perovskite single crystals can narrow down their effective optical bandgap without changing the composition. Thin methylammonium lead triiodide single crystals with tuned thickness of tens of micrometers are directly grown on hole-transport-layer covered substrates by a hydrophobic interface confined lateral crystal growth method. The spectral response of the methylammonium lead triiodide single crystal solar cells is extended to 820 nm, 20 nm broader than the corresponding polycrystalline thin-film solar cells. The open-circuit voltage and fill factor are not sacrificed, resulting in an efficiency of 17.8% for single crystal perovskite solar cells. PMID- 29192233 TI - Kaempferide Prevents Titanium Particle Induced Osteolysis by Suppressing JNK Activation during Osteoclast Formation. AB - Kaempferide (KF) is an O-methylated flavonol, a natural plant extract, which is often found in Kaempferia galanga. It has a variety of effects including anti carcinogenic, anti-inflammatory, anti-oxidant, anti-bacterial and anti-viral properties. In this study, we aimed to investigate whether KF effectively inhibits titanium particle induced calvarial bone loss via down regulation of the JNK signaling pathway. In the mice with titanium particle induced calvarial osteolysis, the Low dose of KF mildly reduced the resorption pits while in the high dose group, fewer scattered pits were observed on the surface of calvarium. Histological examination showed fewer osteoclasts formation in the KF group. In mouse bone marrow macrophages (BMMs) and RAW264.7 cells, KF significantly inhibited the osteoclast formation and bone resorption at 12.5 MUM. However, KF does not affect the mature osteoclast F-actin ring formation. But when being co treated with KF and anisomycin, BMMs differentiated into mature osteoclasts. At the molecular levels, the JNK phosphorylation was inhibited and the osteoclastogenesis-related specific gene expression including V-ATPase d2, TRAP, calcitonin receptor (CTR), c-Fos and NFATc1 was markedly suppressed. In conclusion, these results indicated that KF is a promising agent in the treatment of osteoclast-related diseases. PMID- 29192234 TI - Architectural diversity and galling insects on Caryocar brasiliense trees. AB - Galling insects are a highly sophisticated herbivore group on Caryocar brasiliense, a tree that represents the main income source for many communities. The effect of architectural diversity of C. brasiliense trees on galling insect community diversity and abundance was studied. The abundance of adult insects and galled leaves were seven and 1.6 times higher in trees with a greater height/width of canopy (RHW) ratio, respectively. Gall parasitoid richness was 1.8 times greater on trees with higher RHW. Zelus armillatus (Lepeletier & Serville) (Hemiptera: Reduviidae) and ant numbers were 5.8 and 2.7 higher on trees with the largest and smallest RHW, respectively. More complex plant architectures favored species diversity for galling insects and their natural enemies. The competition among four galling insect species for space and feeding and the evidence of "prudence strategy" were, for the first time, observed for galling insects in the Brazilian Cerrado biome. PMID- 29192235 TI - Multiplex single-cell visualization of nucleic acids and protein during HIV infection. AB - Technical limitations in simultaneous microscopic visualization of RNA, DNA, and proteins of HIV have curtailed progress in this field. To address this need we develop a microscopy approach, multiplex immunofluorescent cell-based detection of DNA, RNA and Protein (MICDDRP), which is based on branched DNA in situ hybridization technology. MICDDRP enables simultaneous single-cell visualization of HIV (a) spliced and unspliced RNA, (b) cytoplasmic and nuclear DNA, and (c) Gag. We use MICDDRP to visualize incoming capsid cores containing RNA and/or nascent DNA and follow reverse transcription kinetics. We also report transcriptional "bursts" of nascent RNA from integrated proviral DNA, and concomitant HIV-1, HIV-2 transcription in co-infected cells. MICDDRP can be used to simultaneously detect multiple viral nucleic acid intermediates, characterize the effects of host factors or drugs on steps of the HIV life cycle, or its reactivation from the latent state, thus facilitating the development of antivirals and latency reactivating agents. PMID- 29192236 TI - Estrogen attenuates AGTR1 expression to reduce pancreatic beta-cell death from high glucose. AB - Chronic exposure of pancreatic beta-cells to high glucose levels results in beta cell dysfunction and death. These effects can be protected by estrogen. The local pancreatic renin-angiotensin system (RAS) has been shown as a novel pathological pathway of high-glucose-induced cell death. The effect of estrogen on pancreatic RAS is still unknown. This study examines whether estrogen protects against pancreatic beta-cell death caused by glucotoxicity via a decrease in the pancreatic beta-cell RAS pathway. When INS-1 cells were cultured in a high glucose medium, cell death was significantly higher than when the cells were cultured in a basal glucose medium; similarly, there were also higher levels of AGTR1 and p47 ph degrees x mRNA, and protein expression. Moreover, the addition of 10-8 M 17beta-estradiol to INS-1 cells cultured in a high glucose medium markedly reduced cell death, AGTR1 and p47 ph degrees x mRNA levels, and protein expression. Similar results were demonstrated in the pancreatic islets. The presence of 10-8 M 17beta-estradiol, losartan, or a combination of both, in a high glucose medium had similar levels of reduction of p47 ph degrees x mRNA and protein expression, compared with those cultured in high glucose. Taken together, estrogen protected pancreatic beta-cells from high-glucose-induced cell death by reducing the AGTR1 pathway.

PMID- 29192238 TI - Evaluation of reported pathogenic variants and their frequencies in a Japanese population based on a whole-genome reference panel of 2049 individuals. AB - Clarifying allele frequencies of disease-related genetic variants in a population is important in genomic medicine; however, such data is not yet available for the Japanese population. To estimate frequencies of actionable pathogenic variants in the Japanese population, we examined the reported pathological variants in genes recommended by the American College of Medical Genetics and Genomics (ACMG) in our reference panel of genomic variations, 2KJPN, which was created by whole genome sequencing of 2049 individuals of the resident cohort of the Tohoku Medical Megabank Project. We searched for pathogenic variants in 2KJPN for 57 autosomal ACMG-recommended genes responsible for 26 diseases and then examined their frequencies. By referring to public databases of pathogenic variations, we identified 143 reported pathogenic variants in 2KJPN for the 57 ACMG recommended genes based on a classification system. At the individual level, 21% of the individuals were found to have at least one reported pathogenic allele. We then conducted a literature survey to review the variants and to check for evidence of pathogenicity. Our results suggest that a substantial number of people have reported pathogenic alleles for the ACMG genes, and reviewing variants is indispensable for constructing the information infrastructure of genomic medicine for the Japanese population. PMID- 29192240 TI - Characterization of the B-cell receptor repertoires in peanut allergic subjects undergoing oral immunotherapy. AB - B-cell receptors (BCRs) play a critical role in adaptive immunity as they generate highly diverse immunoglobulin repertoires to recognize a wide variety of antigens. To better understand immune responses, it is critically important to establish a quantitative and rapid method to analyze BCR repertoire comprehensively. Here, we developed "Bcrip", a novel approach to characterize BCR repertoire by sequencing millions of BCR cDNA using next-generation sequencer. Using this method and quantitative real-time PCR, we analyzed expression levels and repertoires of BCRs in a total of 17 peanut allergic subjects' peripheral blood samples before and after receiving oral immunotherapy (OIT) or placebo. By our methods, we successfully identified all of variable (V), joining (J), and constant (C) regions, in an average of 79.1% of total reads and 99.6% of these VJC-mapped reads contained the C region corresponding to the isotypes that we aimed to analyze. In the 17 peanut allergic subjects' peripheral blood samples, we observed an oligoclonal enrichment of certain immunoglobulin heavy chain alpha (IGHA) and IGH gamma (IGHG) clones (P = 0.034 and P = 0.027, respectively) in peanut allergic subjects after OIT. This newly developed BCR sequencing and analysis method can be applied to investigate B-cell repertoires in various research areas, including food allergies as well as autoimmune and infectious diseases. PMID- 29192241 TI - MicroRNA-21 regulates Osteogenic Differentiation of Periodontal Ligament Stem Cells by targeting Smad5. AB - Human periodontal ligament stem cells (hPDLSCs) are mesenchymal stem cells (MSCs) derived from dental and craniofacial tissues that exhibit high potential for differentiation into osteoblasts. Recently, microRNAs (miRNAs) have been established to play important roles in MSC osteogenesis. In the current study, we report that miR-21 was down-regulated in osteogenically differentiated PDLSCs. Overexpression of miR-21 significantly inhibited osteogenesis of hPDLSC, whereas its inhibition demonstrated the opposite effects. Furthermore, SMAD family member 5 (Smad5) was predicted to be a downstream target of miR-21 and was shown to undergo up-regulation in PDLSCs induced toward osteogenesis. Moreover, Smad5 and Runx2, which are the critical transcription factors in osteogenic differentiation, were predicted to be targets of miR-21. Suppression of miR-21 expression increased the level of Smad5 in vitro and during in vivo transplantation experiments. Furthermore, suppression of Smad5 inhibited osteogenic differentiation and decreased the protein level of Runx2. Taken together, these results suggested that miR-21 be mechanistically implicated in the regulation of osteogenic differentiation of hPDLSCs by targeting Smad5.

AB - Understanding the basis of regeneration of each tissue and organ, and incorporating this knowledge into clinical treatments for degenerative tissues and organs in patients, are major goals for researchers in regenerative biology. Here we provide an overview of current work, from high-regeneration animal models, to stem cell-based culture models, transplantation technologies, large animal chimeric models, and programmable nuclease-based genome-editing technologies. Three-dimensional culture generating organoids, which represents intact tissue/organ identity including cell fate and morphology are getting more general approaches in the fields by taking advantage of embryonic stem cells, induced pluripotent stem cells and adult stem cells. The organoid culture system potentially has profound impact on the field of regenerative medicine. We also emphasize that the large animal model, in particular pig model would be a hope to manufacture humanized organs in in vivo empty (vacant) niche, which now potentially allows not only appropriate cell fate identity but nearly the same property as human organs in size. Therefore, integrative and collaborative researches across different fields might be critical to the aims needed in clinical trial.

AB - Large quantities of impact-related microspherules have been found in fine-grained sediments retained within seven out of nine, radiocarbon-dated, Late Pleistocene mammoth (Mammuthus primigenius) and bison (Bison priscus) skull fragments. The well-preserved fossils were recovered from frozen "muck" deposits (organic-rich silt) exposed within the Fairbanks and Klondike mining districts of Alaska, USA, and the Yukon Territory, Canada. In addition, elevated platinum abundances were found in sediment analysed from three out of four fossil skulls. In view of this new evidence, the mucks and their well-preserved but highly disrupted and damaged vertebrate and botanical remains are reinterpreted in part as blast deposits that resulted from several episodes of airbursts and ground/ice impacts within the northern hemisphere during Late Pleistocene time (~46-11 ka B.P.). Such a scenario might be explained by encounters with cometary debris in Earth-crossing orbits (Taurid Complex) that was generated by fragmentation of a large short period comet within the inner Solar System.

AB - Although runt-related transcription factor 1 (RUNX1) and its associating core binding factor-beta (CBFB) play pivotal roles in leukemogenesis, and inhibition of RUNX1 has now been widely recognized as a novel strategy for anti-leukemic therapies, it has been elusive how leukemic cells could acquire the serious resistance against RUNX1-inhibition therapies and also whether CBFB could participate in this process. Here, we show evidence that p53 (TP53) and CBFB are sequentially up-regulated in response to RUNX1 depletion, and their mutual interaction causes the physiological resistance against chemotherapy for acute myeloid leukemia (AML) cells. Mechanistically, p53 induced by RUNX1 gene silencing directly binds to CBFB promoter and stimulates its transcription as well as its translation, which in turn acts as a platform for the stabilization of RUNX1, thereby creating a compensative RUNX1-p53-CBFB feedback loop. Indeed, AML cells derived from relapsed cases exhibited higher CBFB expression levels compared to those from primary AML cells at diagnosis, and these CBFB expressions were positively correlated to those of p53. Our present results underscore the importance of RUNX1-p53-CBFB regulatory loop in the development and/or maintenance of AML cells, which could be targeted at any sides of this triangle in strategizing anti-leukemia therapies.

AB - The conformations of polycarboxylate ether (PCE) type superplasticizer polymers adsorbed on the surface of MgO in cement pore solution are simulated by molecular dynamics (MD). Three types of PCEs commonly applied to concrete are simulated, namely a methacrylate type PCE (PCEM-P), an allyl ether type PCE (PCEA-P), and an isoprenyl ether type PCE (PCEI-P) with ethylene oxide (EO) unit numbers (P) of 25, 34 and 25, respectively. It is observed that the adsorbed layer thickness is inversely proportional to the experimentally measured adsorbed amount at the initial paste flow of 26 +/- 0.5 cm. Simulation results indicate that the adsorbed layer thickness is sensitive to the initial polymer orientations against the model MgO surface. I.e., polymer molecules initially placed parallel/perpendicularly against the MgO surface gradually forms a train shaped or a loop and tail adsorption profile, respectively. As a result, the loop and tail shaped conformation gives a higher layer thickness. PMID- 29192245 TI - Obesity: Ankyrin-B in susceptibility to obesity.

AB - Liver plays a crucial role in controlling energy homeostasis in mammals, although the exact mechanism by which it influences other peripheral tissues has yet to be addressed. Here we show that Creb regulates transcriptional co-activator (Crtc) 2 is a major regulator of whole-body energy metabolism. Crtc2 liver-specific knockout lowers blood glucose levels with improved glucose and insulin tolerance. Liver-specific knockout mice display increased energy expenditure with smaller lipid droplets in adipose depots. Both plasma and hepatic Fgf21 levels are increased in Crtc2 liver-specific knockout mice, as a result of the reduced miR 34a expression regulated by Creb/Crtc2 and the induction of Sirt1 and Pparalpha. Ectopic expression of miR-34a reverses the metabolic changes in knockout liver. We suggest that Creb/Crtc2 negatively regulates the Sirt1/Pparalpha/Fgf21 axis via the induction of miR-34a under diet-induced obesity and insulin-resistant conditions. PMID- 29192249 TI - Multilocus DNA barcoding - Species Identification with Multilocus Data. AB - Species identification using DNA sequences, known as DNA barcoding has been widely used in many applied fields. Current barcoding methods are usually based on a single mitochondrial locus, such as cytochrome c oxidase subunit I (COI). This type of barcoding method does not always work when applied to species separated by short divergence times or that contain introgressed genes from closely related species. Herein we introduce a more effective multi-locus barcoding framework that is based on gene capture and "next-generation" sequencing. We selected 500 independent nuclear markers for ray-finned fishes and designed a three-step pipeline for multilocus DNA barcoding. We applied our method on two exemplar datasets each containing a pair of sister fish species: Siniperca chuatsi vs. Sini. kneri and Sicydium altum vs. Sicy. adelum, where the COI barcoding approach failed. Both of our empirical and simulated results demonstrated that under limited gene flow and enough separation time, we could correctly identify species using multilocus barcoding method. We anticipate that, as the cost of DNA sequencing continues to fall that our multilocus barcoding approach will eclipse existing single-locus DNA barcoding methods as a means to better understand the diversity of the living world. PMID- 29192250 TI - Coupling optogenetics and light-sheet microscopy, a method to study Wnt signaling during embryogenesis. AB - Optogenetics allows precise, fast and reversible intervention in biological processes. Light-sheet microscopy allows observation of the full course of Drosophila embryonic development from egg to larva. Bringing the two approaches together allows unparalleled precision into the temporal regulation of signaling pathways and cellular processes in vivo. To develop this method, we investigated the regulation of canonical Wnt signaling during anterior-posterior patterning of the Drosophila embryonic epidermis. Cryptochrome 2 (CRY2) from Arabidopsis Thaliana was fused to mCherry fluorescent protein and Drosophila beta-catenin to form an easy to visualize optogenetic switch. Blue light illumination caused oligomerization of the fusion protein and inhibited downstream Wnt signaling in vitro and in vivo. Temporal inactivation of beta-catenin confirmed that Wnt signaling is required not only for Drosophila pattern formation, but also for maintenance later in development. We anticipate that this method will be easily extendable to other developmental signaling pathways and many other experimental systems. PMID- 29192251 TI - Access to a main alphaherpesvirus receptor, located basolaterally in the respiratory epithelium, is masked by intercellular junctions. AB - The respiratory epithelium of humans and animals is frequently exposed to alphaherpesviruses, originating from either external exposure or reactivation from latency. To date, the polarity of alphaherpesvirus infection in the respiratory epithelium and the role of respiratory epithelial integrity herein has not been studied. Equine herpesvirus type 1 (EHV1), a well-known member of the alphaherpesvirus family, was used to infect equine respiratory mucosal explants and primary equine respiratory epithelial cells (EREC), grown at the air liquid interface. EHV1 binding to and infection of mucosal explants was greatly enhanced upon destruction of the respiratory epithelium integrity with EGTA or N acetylcysteine. EHV1 preferentially bound to and entered EREC at basolateral cell surfaces. Restriction of infection via apical inoculation was overcome by disruption of intercellular junctions. Finally, basolateral but not apical EHV1 infection of EREC was dependent on cellular N-linked glycans. Overall, our findings demonstrate that integrity of the respiratory epithelium is crucial in the host's innate defence against primary alphaherpesvirus infections. In addition, by targeting a basolaterally located receptor in the respiratory epithelium, alphaherpesviruses have generated a strategy to efficiently escape from host defence mechanisms during reactivation from latency. PMID- 29192253 TI - Chitosan-Graphene Oxide 3D scaffolds as Promising Tools for Bone Regeneration in Critical-Size Mouse Calvarial Defects. AB - Limited self-regenerating capacity of human skeleton makes the reconstruction of critical size bone defect a significant challenge for clinical practice. Aimed for regenerating bone tissues, this study was designed to investigate osteogenic differentiation, along with bone repair capacity of 3D chitosan (CHT) scaffolds enriched with graphene oxide (GO) in critical-sized mouse calvarial defect. Histopathological/histomorphometry and scanning electron microscopy(SEM) analysis of the implants revealed larger amount of new bone in the CHT/GO-filled defects compared with CHT alone (p < 0.001). When combined with GO, CHT scaffolds synergistically promoted the increase of alkaline phosphatase activity both in vitro and in vivo experiments. This enhanced osteogenesis was corroborated with increased expression of bone morphogenetic protein (BMP) and Runx-2 up to week 4 post-implantation, which showed that GO facilitates the differentiation of osteoprogenitor cells. Meanwhile, osteogenesis was promoted by GO at the late stage as well, as indicated by the up-regulation of osteopontin and osteocalcin at week 8 and overexpressed at week 18, for both markers. Our data suggest that CHT/GO biomaterial could represent a promising tool for the reconstruction of large bone defects, without using exogenous living cells or growth factors. PMID- 29192252 TI - Restoration of patterned vision with an engineered photoactivatable G protein coupled receptor. AB - Retinitis pigmentosa results in blindness due to degeneration of photoreceptors, but spares other retinal cells, leading to the hope that expression of light activated signaling proteins in the surviving cells could restore vision. We used a retinal G protein-coupled receptor, mGluR2, which we chemically engineered to respond to light. In retinal ganglion cells (RGCs) of blind rd1 mice, photoswitch charged mGluR2 ("SNAG-mGluR2") evoked robust OFF responses to light, but not in wild-type retinas, revealing selectivity for RGCs that have lost photoreceptor input. SNAG-mGluR2 enabled animals to discriminate parallel from perpendicular lines and parallel lines at varying spacing. Simultaneous viral delivery of the inhibitory SNAG-mGluR2 and excitatory light-activated ionotropic glutamate receptor LiGluR yielded a distribution of expression ratios, restoration of ON, OFF and ON-OFF light responses and improved visual acuity. Thus, SNAG-mGluR2 restores patterned vision and combinatorial light response diversity provides a new logic for enhanced-acuity retinal prosthetics. PMID- 29192254 TI - Effect of Src Kinase inhibition on Cytochrome c, Smac/DIABLO and Apoptosis Inducing Factor (AIF) Following Cerebral Hypoxia-Ischemia in Newborn Piglets. AB - We have previously shown that cerebral Hypoxia-ischemia (HI) results in activation of Src kinase in the newborn piglet brain. We investigated the regulatory mechanism by which the pre-apoptotic proteins translocate from mitochondria to the cytosol during HI through the Src kinase. Newborn piglets were divided into 3 groups (n = 5/group): normoxic (Nx), HI and HI pre-treated with Src kinase inhibitor PP2 (PP2 + HI). Brain tissue HI was verified by neuropathological analysis and by Adenosine Triphosphate (ATP) and Phosphocreatine (PCr) levels. We used western blots, immunohistochemistry, H&E and biochemical enzyme assays to determine the role of Src kinase on mitochondrial membrane apoptotic protein trafficking. HI resulted in decreased ATP and PCr levels, neuropathological changes and increased levels of cytochrome c, Smac/DIABLO and AIF in the cytosol while their levels were decreased in mitochondria compared to Nx. PP2 decreased the cytosolic levels of pre-apoptotic proteins, attenuated the neuropathological changes and apoptosis and decreased the HI-induced increased activity of caspase-3. Our data suggest that Src kinase may represent a potential target that could interrupt the enzymatic activation of the caspase dependent cell death pathway. PMID- 29192255 TI - The mitochondrial genome of the wolfberry fruit fly, Neoceratitis asiatica (Becker) (Diptera: Tephritidae) and the phylogeny of Neoceratitis Hendel genus. AB - Neoceratitis asiatica (Becker) (Diptera: Tephritidae) is one of the most important fruit pestsof wolfberry which is a traditional Chinese medicinal herb. We characterized the complete mitochondrial genome of N. asiatica and described its organization in this study. This mitogenome had a total length of 15,481 bp, consisting of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a non coding region (A + T-rich control region). The overall base composition of N. asiatica in descending order was 40.6% A, 8.5% G, 38.4% T and 12.6% C. The phylogenetic relationships shows that Ceratitis capitata and N. asiatica may be sister taxa. This is the first report of the complete mitochondrial genome of a member of the Neoceratitis Genus and the complete mitochondrial genome sequence may provide useful information for phylogenetic analysis and studies between the genera Ceratitis and Neoceratitis. PMID- 29192256 TI - Posterior parietal cortex evaluates visuoproprioceptive congruence based on brief visual information. AB - To represent one's upper limbs for action, the brain relies on a combined position estimate based on visual and proprioceptive information. Monkey neurophysiology and human brain imaging suggest that the underlying operations are implemented in a network of fronto-parietal and occipitotemporal cortical areas. Recently, a potential hierarchical arrangement of these areas has been proposed, emphasizing the posterior parietal cortex (PPC) in early multisensory comparison and integration. Here, we used functional magnetic resonance imaging (fMRI) and a virtual reality-based setup to briefly (0.5 s) present healthy human participants photorealistic virtual hands, of matching or nonmatching anatomical side, or objects at the same or a different location than their real hidden left or right hand. The inferior parietal lobe (IPL) of the left PPC showed a significant preference for congruent visuoproprioceptive hand position information. Moreover, the left body part-selective extrastriate body area (EBA; functionally localized) significantly increased its coupling with the left IPL during visuoproprioceptive congruence vs. incongruence. Our results suggest that the PPC implements early visuoproprioceptive comparison and integration processes, likely relying on information exchange with the EBA.

AB - Antisense oligonucleotides (ASOs) were first discovered to influence RNA processing and modulate protein expression over two decades ago; however, progress translating these agents into the clinic has been hampered by inadequate target engagement, insufficient biological activity, and off-target toxic effects. Over the years, novel chemical modifications of ASOs have been employed to address these issues. These modifications, in combination with elucidation of the mechanism of action of ASOs and improved clinical trial design, have provided momentum for the translation of ASO-based strategies into therapies. Many neurological conditions lack an effective treatment; however, as research progressively disentangles the pathogenic mechanisms of these diseases, they provide an ideal platform to test ASO-based strategies. This steady progress reached a pinnacle in the past few years with approvals of ASOs for the treatment of spinal muscular atrophy and Duchenne muscular dystrophy, which represent landmarks in a field in which disease-modifying therapies were virtually non existent. With the rapid development of improved next-generation ASOs toward clinical application, this technology now holds the potential to have a dramatic effect on the treatment of many neurological conditions in the near future. PMID- 29192263 TI - Comprehensive high-throughput image analysis for therapeutic efficacy of architecturally complex heterotypic organoids. AB - Bioengineered three-dimensional (3D) tumor models that incorporate heterotypic cellular communication are gaining interest as they can recapitulate key features regarding the intrinsic heterogeneity of cancer tissues. However, the architectural complexity and heterogeneous contents associated with these models pose a challenge for toxicological assays to accurately report treatment outcomes. To address this issue, we describe a comprehensive image analysis procedure for structurally complex organotypic cultures (CALYPSO) applied to fluorescence-based assays to extract multiparametric readouts of treatment effects for heterotypic tumor cultures that enables advanced analyses. The capacity of this approach is exemplified on various 3D models including adherent/suspension, mono-/heterocellular cultures and several disease types. The subsequent analysis revealed specific morphological effects of oxaliplatin chemotherapy, radiotherapy, and photodynamic therapy. The procedure can be readily implemented in most laboratories to facilitate high-throughput toxicological screening of pharmaceutical agents and treatment regimens on organotypic cultures of human disease to expedite drug and therapy development.

PMID- 29192270 TI - HIDEEP: a systems approach to predict hormone impacts on drug efficacy based on effect paths. AB - Experimental evidence has shown that some of the human endogenous hormones significantly affect drug efficacy. Since hormone status varies with individual physiological states, it is essential to understand the interplay of hormones and drugs for precision medicine. Here, we developed an in silico method to predict interactions between 283 human endogenous hormones and 590 drugs for 20 diseases including cancers and non-cancer diseases. We extracted hormone effect paths and drug effect paths from a large-scale molecular network that contains protein interactions, transcriptional regulations, and signaling interactions. If two kinds of effect paths for a hormone-drug pair intersect closely, we expect that the influence of the hormone on the drug efficacy is significant. It has been shown that the proposed method correctly distinguishes hormone-drug pairs with known interactions from random pairs in blind experiments. In addition, the method can suggest underlying interaction mechanisms at the molecular level so that it helps us to better understand the interplay of hormones and drugs. PMID- 29192271 TI - Tailoring magnetic properties of multicomponent layered structure via current annealing in FePd thin films. AB - Multicomponent layered systems with tailored magnetic properties were fabricated via current annealing from homogeneous Fe67Pd33 thin films, deposited via radio frequency sputtering on Si/SiO2 substrates from composite target. To promote spontaneous nano-structuring and phase separation, selected samples were subjected to current annealing in vacuum, with a controlled oxygen pressure, using various current densities for a fixed time and, as a consequence, different phases and microstructures were obtained. In particular, the formation of magnetite in different amount was observed beside other iron oxides and metallic phases. Microstructures and magnetic properties evolution as a function of annealing current were studied and interpreted with different techniques. Moreover, the temperature profile across the film thickness was modelled and its role in the selective oxidation of iron was analysed. Results show that is possible to topologically control the phases formation across the film thickness and simultaneously tailor the magnetic properties of the system.

PMID- 29192272 TI - Ribosomal stress and Tp53-mediated neuronal apoptosis in response to capsid protein of the Zika virus. AB - We report here that in rat and human neuroprogenitor cells as well as rat embryonic cortical neurons Zika virus (ZIKV) infection leads to ribosomal stress that is characterized by structural disruption of the nucleolus. The anti nucleolar effects were most pronounced in postmitotic neurons. Moreover, in the latter system, nucleolar presence of ZIKV capsid protein (ZIKV-C) was associated with ribosomal stress and apoptosis. Deletion of 22 C-terminal residues of ZIKV-C prevented nucleolar localization, ribosomal stress and apoptosis. Consistent with a casual relationship between ZIKV-C-induced ribosomal stress and apoptosis, ZIKV C-overexpressing neurons were protected by loss-of-function manipulations targeting the ribosomal stress effector Tp53 or knockdown of the ribosomal stress mediator RPL11. Finally, capsid protein of Dengue virus, but not West Nile virus, induced ribosomal stress and apoptosis. Thus, anti-nucleolar and pro-apoptotic effects of protein C are flavivirus-species specific. In the case of ZIKV, capsid protein-mediated ribosomal stress may contribute to neuronal death, neurodevelopmental disruption and microcephaly. PMID- 29192274 TI - Synthesis of structurally controlled hyperbranched polymers using a monomer having hierarchical reactivity. AB - Hyperbranched polymers (HBPs) have attracted significant attention because of their characteristic topological structure associated with their unique physical properties compared with those of the corresponding linear polymers. Dendrimers are the most structurally controlled HBPs, but the necessity of a stepwise synthesis significantly limits their applications in materials science. Several methods have been developed to synthesize HBPs by a one-step procedure, as exemplified by the use of AB2 monomers and AB' inimers under condensation and self-condensing vinyl polymerization conditions. However, none of these methods provides structurally controlled HBPs over the three-dimensional (3D) structure, i.e., molecular weight, dispersity, number of branching points, branching density, and chain-end functionalities, except under special conditions. Here, we introduce a monomer design concept involving two functional groups with hierarchical reactivity and demonstrate the controlled synthesis of dendritic HBPs over the 3D structure by the copolymerization of the designed monomer and acrylates under living radical polymerization conditions. PMID- 29192275 TI - The habitability of the Milky Way during the active phase of its central supermassive black hole. AB - During the peak of their accretion phase, supermassive black holes in galactic cores are known to emit very high levels of ionizing radiation, becoming visible over intergalactic distances as quasars or active galactic nuclei (AGN). Here, we quantify the extent to which the activity of the supermassive black hole at the center of the Milky Way, known as Sagittarius A* (Sgr A*), may have affected the habitability of Earth-like planets in our Galaxy. We focus on the amount of atmospheric loss and on the possible biological damage suffered by planets exposed to X-ray and extreme ultraviolet (XUV) radiation produced during the peak of the active phase of Sgr A*. We find that terrestrial planets could lose a total atmospheric mass comparable to that of present day Earth even at large distances (~1 kiloparsec) from the galactic center. Furthermore, we find that the direct biological damage caused by Sgr A* to surface life on planets not properly screened by an atmosphere was probably significant during the AGN phase, possibly hindering the development of complex life within a few kiloparsecs from the galactic center. PMID- 29192276 TI - Protein-lysine methyltransferases G9a and GLP1 promote responses to DNA damage. AB - Upon induction of DNA breaks, ATM activation leads to a cascade of local chromatin modifications that promote efficient recruitment of DNA repair proteins. Errors in this DNA repair pathway lead to genomic instability and cancer predisposition. Here, we show that the protein lysine methyltransferase G9a (also known as EHMT2) and GLP1 (also known as EHMT1) are critical components of the DNA repair pathway. G9a and GLP1 rapidly localizes to DNA breaks, with GLP1 localization being dependent on G9a. ATM phosphorylation of G9a on serine 569 is required for its recruitment to DNA breaks. G9a catalytic activity is required for the early recruitment of DNA repair factors including 53BP and BRCA1 to DNA breaks. Inhibition of G9a catalytic activity disrupts DNA repair pathways and increases sensitivity to ionizing radiation. Thus, G9a is a potential therapeutic target in the DNA repair pathway. PMID- 29192277 TI - Graphene-edge dielectrophoretic tweezers for trapping of biomolecules. AB - The many unique properties of graphene, such as the tunable optical, electrical, and plasmonic response make it ideally suited for applications such as biosensing. As with other surface-based biosensors, however, the performance is limited by the diffusive transport of target molecules to the surface. Here we show that atomically sharp edges of monolayer graphene can generate singular electrical field gradients for trapping biomolecules via dielectrophoresis. Graphene-edge dielectrophoresis pushes the physical limit of gradient-force-based trapping by creating atomically sharp tweezers. We have fabricated locally backgated devices with an 8-nm-thick HfO2 dielectric layer and chemical-vapor deposited graphene to generate 10* higher gradient forces as compared to metal electrodes. We further demonstrate near-100% position-controlled particle trapping at voltages as low as 0.45 V with nanodiamonds, nanobeads, and DNA from bulk solution within seconds. This trapping scheme can be seamlessly integrated with sensors utilizing graphene as well as other two-dimensional materials. PMID- 29192278 TI - Profiling of different pancreatic cancer cells used as models for metastatic behaviour shows large variation in their N-glycosylation. AB - To characterise pancreatic cancer cells from different sources which are used as model systems to study the metastatic behaviour in pancreatic ductal adenocarcinoma (PDAC), we compared the N-glycan imprint of four PDAC cells which were previously shown to differ in their galectin-4 expression and metastatic potential in vivo. Next to the sister cell lines Pa-Tu-8988S and Pa-Tu-8988T, which were isolated from the same liver metastasis of a PDAC, this included two primary PDAC cell cultures, PDAC1 and PDAC2. Additionally, we extended the N glycan profiling to a normal, immortalized pancreatic duct cell line. Our results revealed major differences in the N-glycosylation of the different PDAC cells as well as compared to the control cell line, suggesting changes of the N glycosylation in PDAC. The N-glycan profiles of the PDAC cells, however, differed vastly as well and demonstrate the diversity of PDAC model systems, which ultimately affects the interpretation of functional studies. The results from this study form the basis for further biological evaluation of the role of protein glycosylation in PDAC and highlight that conclusions from one cell line cannot be generalised, but should be regarded in the context of the corresponding phenotype. PMID- 29192279 TI - Self-righting potential and the evolution of shell shape in Galapagos tortoises. AB - Self-righting, the capacity of an animal to self-turn after falling on its back, is a fitness-related trait. Delayed self-righting can result in loss of mating opportunities or death. Traits involved in self-righting may therefore be under selection. Galapagos giant tortoises have two main shell morphologies - saddleback and domed - that have been proposed to be adaptive. The more sloped shape on the sides of the shell and the longer extension of neck and legs of the saddlebacks could have evolved to optimize self-righting. The drier environments with more uneven surfaces where the saddleback tortoises occur increases their risk to fall on their back while walking. The ability to fast overturn could reduce the danger of dying. To test this hypothesis, we used 3D shell reconstructions of 89 Galapagos giant tortoises from three domed and two saddleback species to compare self-righting potential of the two shell morphotypes. Our results indicate that saddleback shells require higher energy input to self-right than domed ones. This suggests that several traits associated with the saddleback shell morphology could have evolved to facilitate self righting. Studying the functional performances of fitness-related traits, as in this work, could provide important insight into the adaptive value of traits. PMID- 29192280 TI - Improved Detection of Cytokines Produced by Invariant NKT Cells. AB - Invariant Natural killer T (iNKT) cells rapidly produce copious amounts of multiple cytokines after in vivo activation, allowing for the direct detection of a number of cytokines directly ex vivo. However, for some cytokines this approach is suboptimal. Here, we report technical variations that allow the improved detection of IL-4, IL-10, IL-13 and IL-17A ex vivo. Furthermore, we describe an alternative approach for stimulation of iNKT cells in vitro that allows a significantly improved detection of cytokines produced by iNKT cells. Together, these protocols allow the detection of iNKT cell cytokines ex vivo and in vitro with increased sensitivity. PMID- 29192281 TI - High-speed, high-frequency ultrasound, in utero vector-flow imaging of mouse embryos. AB - Real-time imaging of the embryonic murine cardiovascular system is challenging due to the small size of the mouse embryo and rapid heart rate. High-frequency, linear-array ultrasound systems designed for small-animal imaging provide high frame-rate and Doppler modes but are limited in regards to the field of view that can be imaged at fine-temporal and -spatial resolution. Here, a plane-wave imaging method was used to obtain high-speed image data from in utero mouse embryos and multi-angle, vector-flow algorithms were applied to the data to provide information on blood flow patterns in major organs. An 18-MHz linear array was used to acquire plane-wave data at absolute frame rates >=10 kHz using a set of fixed transmission angles. After beamforming, vector-flow processing and image compounding, effective frame rates were on the order of 2 kHz. Data were acquired from the embryonic liver, heart and umbilical cord. Vector-flow results clearly revealed the complex nature of blood-flow patterns in the embryo with fine-temporal and -spatial resolution. PMID- 29192282 TI - Functionalized gold nanorod nanocomposite system to modulate differentiation of human mesenchymal stem cells into neural-like progenitors. AB - A 2D multifunctional nanocomposite system of gold nanorods (AuNRs) was developed. Gold nanorods were functionalized via polyethylene glycol with a terminal amine, and, were characterized using transmission and scanning electron microscopy, ultra violet-visible and X-ray photoelectron spectroscopy, and Zeta-potential. The system was cytocompatible to and maintained the integrity of Schwann cells. The neurogenic potential of adipose tissue - derived human mesenchymal stem cells (hMSCs) was evaluated in vitro. The expression pattern and localization of Vimentin confirmed the mesenchymal origin of cells and tracked morphological changes during differentiation. The expression patterns of S100beta and glial fibrillary acidic protein (GFAP), were used as indicator for neural differentiation. Results suggested that this process was enhanced when the cells were seeded on the AuNRs compared to the tissue-culture surface. The present study indicates that the design and the surface properties of the AuNRs enhances neural differentiation of hMSCs and hence, would be beneficial for neural tissue engineering scaffolds.

AB - Multi-material systems interfaced with 2D materials, or entirely new 3D heterostructures can lead to the next generation multi-functional device architectures. Physical and chemical control at the nanoscale is also necessary tailor these materials as functional structures approach physical limit. 2D transition metal thiophosphates (TPS), with a general formulae Cu1-xIn1+x/3P2S6, have shown ferroelectric polarization behavior with a T c above the room temperature, making them attractive candidates for designing both: chemical and physical properties. Our previous studies have demonstrated that ferroic order persists on the surface, and that spinoidal decomposition of ferroelectric and paraelectric phases occurs in non-stoichiometric Cu/In ratio formulations. Here, we discuss the chemical changes induced by helium ion irradiation. We explore the TPS compound library with varying Cu/In ratio, using Helium Ion Microscopy, Atomic Force Microscopy (AFM), and Time of Flight-Secondary Ion Mass Spectrometry (ToF-SIMS). We correlate physical nano- and micro- structures to the helium ion dose, as well as chemical signatures of copper, oxygen and sulfur.

AB - The challenges of seasonal environments are thought to contribute to brain evolution, but in which way is debated. According to the Cognitive Buffer Hypothesis (CBH) brain size should increase with seasonality, as the cognitive benefits of a larger brain should help overcoming periods of food scarcity via, for instance, increased behavioral flexibility. However, in line with the Expensive Brain Framework (EBF) brain size should decrease with seasonality because a smaller brain confers energetic benefits in periods of food scarcity. Empirical evidence is inconclusive and mostly limited to homoeothermic animals. Here we used phylogenetic comparative analyses to test the impact of seasonality on brain evolution across 30 species of anurans (frogs) experiencing a wide range of temperature and precipitation. Our results support the EBF because relative brain size and the size of the optic tectum were negatively correlated with variability in temperature. In contrast, we found no association between the variability in precipitation and the length of the dry season with either brain size or the sizes of other major brain regions. We suggest that seasonality induced food scarcity resulting from higher variability in temperature constrains brain size evolution in anurans. Less seasonal environments may therefore facilitate the evolution of larger brains in poikilothermic animals.

AB - Given the therapeutic and commercial success of small-molecule enzyme inhibitors, as exemplified by kinase inhibitors in oncology, a major focus of current drug discovery and development efforts is on enzyme targets. Understanding the course of an enzyme-catalysed reaction can help to conceptualize different types of inhibitor and to inform the design of screens to identify desired mechanisms. Exploiting this information allows the thorough evaluation of diverse compounds, providing the knowledge required to efficiently optimize leads towards differentiated candidate drugs. This review highlights the rationale for conducting high-quality mechanistic enzymology studies and considers the added value in combining such studies with orthogonal biophysical methods. PMID- 29192288 TI - Optical charge state control of spin defects in 4H-SiC. AB - Defects in silicon carbide (SiC) have emerged as a favorable platform for optically active spin-based quantum technologies. Spin qubits exist in specific charge states of these defects, where the ability to control these states can provide enhanced spin-dependent readout and long-term charge stability. We investigate this charge state control for two major spin qubits in 4H-SiC, the divacancy and silicon vacancy, obtaining bidirectional optical charge conversion between the bright and dark states of these defects. We measure increased photoluminescence from divacancy ensembles by up to three orders of magnitude using near-ultraviolet excitation, depending on the substrate, and without degrading the electron spin coherence time. This charge conversion remains stable for hours at cryogenic temperatures, allowing spatial and persistent patterning of the charge state populations. We develop a comprehensive model of the defects and optical processes involved, offering a strong basis to improve material design and to develop quantum applications in SiC. PMID- 29192289 TI - Caspase-3/-7-Specific Metabolic Precursor for Bioorthogonal Tracking of Tumor Apoptosis. AB - Apoptosis is one of the most important intracellular events in living cell, which is a programmed cell death interrelated with caspase enzyme activity for maintaining homeostasis in multicellular organisms. Therefore, direct apoptosis imaging of living cells can provide enormous advantages for diagnosis, drug discovery, and therapeutic monitoring in various diseases. However, a method of direct apoptosis imaging has not been fully validated, especially for live cells in in vitro and in vivo. Herein, we developed a new apoptosis imaging technology via a direct visualization of active caspase-3/-7 activity in living cells. For this, we synthesized a caspase-3/-7-specific cleavable peptide (KGDEVD) conjugated triacetylated N-azidoacetyl-D-mannosamine (Apo-S-Ac3ManNAz), wherein the Apo-S-Ac3ManNAz can be cleaved by the active caspase-3/-7 in live apoptotic cells and the cleaved Ac3ManNAz molecules can further generate targetable azido groups (N3) on the living cell surface. Importantly, the azido groups on the apoptotic tumor cells could be visualized with Cy5.5-conjugated dibenzylcyclooctyne (DBCO-Cy5.5) via bioorthogonal click chemistry in vitro cell culture condition and in vivo tumor-bearing mice. Therefore, our Apo-S-Ac3ManNAz can be utilized for the further applications in tumor therapy as a monitoring tool for anticancer efficacy and optimization of anticancer new drugs in cell culture system and in tumor-bearing mice. PMID- 29192290 TI - Direct conversion of human fibroblasts into hepatocyte-like cells by ATF5, PROX1, FOXA2, FOXA3, and HNF4A transduction. AB - Recently, it has been reported that human hepatocyte-like cells can be generated from fibroblasts by direct reprogramming technology. However, the conversion efficiency of human induced hepatocyte-like cells (hiHeps) is not high enough. In addition, comparative analysis with the existing models of hepatocytes, such as human iPS cell-derived hepatocyte-like cells and primary human hepatocytes, has not been sufficiently carried out. In this study, we screened hepatic transcription factors for efficient direct hepatic reprogramming and compared hepatic functions between hiHeps and other existing hepatocyte models. We found that human fibroblasts were efficiently converted into hiHeps by using a combination of ATF5, PROX1, FOXA2, FOXA3, and HNF4A (albumin+/alpha-1 antitrypsin+ cells = 27%, asialoglycoprotein receptor 1+ cells = 22%). The CYP expression levels and CYP activities in hiHeps were higher than those in human iPS cell-derived hepatocyte-like cells, but lower than those in short-term (4 hr) cultured primary human hepatocytes and primary human hepatocytes collected immediately after thawing. These results suggested that functional hiHeps could be efficiently generated by ATF5, PROX1, FOXA2, FOXA3, and HNF4A transduction. We believe that hiHeps generated by our method will be useful for the drug-discovery activities such as hepatotoxicity screening and drug metabolism tests. PMID- 29192292 TI - Association between central papilla recession and gingival and interdental smile line. AB - OBJECTIVE: Interdental soft tissues play a critical role in pink esthetics. The presence and preservation of the interdental papillae in the esthetic zone is as crucial as the shape and contour of the anterior teeth in achieving an esthetically pleasing smile. The present study determines the association of central papilla recession with gingival and interdental smile line in periodontally healthy patients of different age groups. METHOD AND MATERIALS: The present study included 200 patients equally divided into 21 to 40 years and 41 to 60 years age groups. The clinical and photographic evaluation of the central papilla, with midfacial gingiva, and its relationship with the vermilion border was performed. RESULTS: In total, 137 patients exhibited presence of central papilla, whilst 63 patients had central papilla recession with variable extent. The male patients predominantly had presence of central papilla in both the age groups, with 86% and 64%, compared with 74% and 50% in females, respectively. High gingival smile line was seen in the majority of the patients (62%), and this trend was similar to high interdental smile line (82% of the patients). CONCLUSION: Esthetics is affected in individuals having papilla recession along with high gingival smile line and interdental smile line as compared to individuals with low or cupid bow gingival smile line and interdental smile line. PMID- 29192287 TI - Next generation antibody drugs: pursuit of the 'high-hanging fruit'. AB - Antibodies are the most rapidly growing drug class and have a major impact on human health, particularly in oncology, autoimmunity and chronic inflammatory diseases. Many of the best understood and most tractable cell surface and secreted targets with known roles in human diseases have been extensively exploited for antibody drug development. In this Review, we focus on emerging and novel mechanisms of action of antibodies and innovative targeting strategies that could extend their therapeutic applications, including antibody-drug conjugates, bispecific antibodies and antibody engineering to facilitate more effective delivery. These strategies could enable the pursuit of difficult to hit, less well-understood or previously undruggable targets - the 'high-hanging fruit'. PMID- 29192291 TI - Kif1bp loss in mice leads to defects in the peripheral and central nervous system and perinatal death. AB - Goldberg-Shprintzen syndrome is a poorly understood condition characterized by learning difficulties, facial dysmorphism, microcephaly, and Hirschsprung disease. GOSHS is due to recessive mutations in KIAA1279, which encodes kinesin family member 1 binding protein (KIF1BP, also known as KBP). We examined the effects of inactivation of Kif1bp in mice. Mice lacking Kif1bp died shortly after birth, and exhibited smaller brains, olfactory bulbs and anterior commissures, and defects in the vagal and sympathetic innervation of the gut. Kif1bp was found to interact with Ret to regulate the development of the vagal innervation of the stomach. Although newborn Kif1bp -/- mice had neurons along the entire bowel, the colonization of the gut by neural crest-derived cells was delayed. The data show an essential in vivo role for KIF1BP in axon extension from some neurons, and the reduced size of the olfactory bulb also suggests additional roles for KIF1BP. Our mouse model provides a valuable resource to understand GOSHS. PMID- 29192293 TI - Digital evaluation of the fit of zirconia-reinforced lithium silicate crowns with a new three-dimensional approach. AB - OBJECTIVE: Several methods for the evaluation of fit of computer-aided design/computer-assisted manufacture (CAD/CAM)-fabricated restorations have been described. In the study, digital models were recorded with an intraoral scanning device and were measured using a new three-dimensional (3D) computer technique to evaluate restoration internal fit. The aim of the study was to evaluate the internal adaptation and fit of chairside CAD/CAM-fabricated zirconia-reinforced lithium silicate ceramic crowns fabricated with different post-milling protocols. The null hypothesis was that different post-milling protocols did not influence the fitting accuracy of zirconia-reinforced lithium silicate restorations. METHOD AND MATERIALS: A master all-ceramic crown preparation was completed on a maxillary right first molar on a typodont. Twenty zirconia-reinforced lithium silicate ceramic crowns (Celtra Duo, Dentsply Sirona) were designed and milled using a chairside CAD/CAM system (CEREC Omnicam, Dentsply Sirona). The 20 crowns were randomly divided into two groups based on post-milling protocols: no manipulation after milling (Group MI) and oven fired-glazing after milling (Group FG). A 3D computer method was used to evaluate the internal adaptation of the crowns. This was based on a subtractive analysis of a digital scan of the crown preparation and a digital scan of the thickness of the cement space over the crown preparation as recorded by a polyvinylsiloxane (PVS) impression material. The preparation scan and PVS scan were matched in 3D and a 3D difference analysis was performed with a software program (OraCheck, Cyfex). Three areas of internal adaptation and fit were selected for analysis: margin (MA), axial wall (AX), and occlusal surface (OC). Statistical analysis was performed using 80% percentile and one-way ANOVA with post-hoc Scheffe test (P = .05). RESULTS: The closest internal adaptation of the crowns was measured at the axial wall with 102.0 +/- 11.7 um for group MI-AX and 106.3 +/- 29.3 um for group FG-AX. The largest internal adaptation of the crowns was measured for the occlusal surface with 258.9 +/- 39.2 um for group MI-OC and 260.6 +/- 55.0 um for group FG-OC. No statistically significant differences were found for the post-milling protocols (P > .05). The 3D difference pattern was visually analyzed for each area with a color-coded scheme. CONCLUSION: Post-milling processing did not affect the internal adaptation of zirconia-reinforced lithium silicate crowns fabricated with a chairside CAD/CAM technique. The new 3D computer technique for the evaluation of fit of restorations may be highly promising and has the opportunity to be applied to clinical studies. PMID- 29192294 TI - Primary burning mouth syndrome: Literature review and preliminary findings suggesting possible association with pain modulation. AB - Primary burning mouth syndrome (BMS) is a chronic pain of a burning quality affecting the tongue and intraoral mucosa. Currently, there are no definite diagnostic criteria; therefore, the diagnosis is made by exclusion of potential local and systemic causes that could justify the burning sensation. The etiology behind primary BMS remains unclear; however, the most acceptable theories link primary BMS with neuropathic pain. This article provides a review of primary BMS diagnosis, mechanisms, and treatment with focus on the association of BMS with pain modulation. Preliminary data are presented suggesting a link between primary BMS and a faulty inhibitory pain system. PMID- 29192295 TI - High-performance liquid chromatography mass spectrometry of gold and alloy clusters protected by hydrophilic thiolates. AB - In this work, we found two hydrophilic interaction liquid chromatography (HILIC) columns for high-performance liquid chromatography (HPLC) suitable for the high resolution separation of hydrophilic metal clusters. The mass distributions of the product mixtures of hydrophilic metal clusters were evaluated via HPLC mass spectrometry (LC/MS) using these HILIC columns. Consequently, we observed multiple clusters that had not been previously reported for glutathionate (SG) protected gold clusters (Aun(SG)m). Additionally, we demonstrated that Aun xMx(SG)m alloy clusters (M = Ag, Cu, or Pd) in which part of the Au in the Aun(SG)m cluster is replaced by a heteroelement can be synthesized, similar to the case of hydrophobic alloy clusters. It is easy to evaluate the mass distributions of hydrophilic metal clusters using this method. Thus, remarkable progress in the synthesis techniques of hydrophilic metal clusters through the use of this method is anticipated, as is the situation for hydrophobic metal clusters. PMID- 29192296 TI - Reaction mechanism of hydrogen evolution catalysed by Co and Fe complexes containing a tetra-dentate phosphine ligand - a DFT study. AB - The reaction mechanism of the electro-catalytic proton reduction in neutral phosphate buffer enabled by mononuclear cobalt and iron complexes containing a tetra-dentate phosphine ligand (MP4N2, M = Fe, Co) has been elucidated by density functional calculations. The phosphate from the buffer was found to play a crucial role by coordinating to the metal and delivering a proton to the metal hydride in the H-H bond formation. For the more efficient cobalt catalyst, the starting species is a CoII complex with a hydrogen phosphate and a water molecule ligated at the two vacant coordination sites. Two sequential proton-coupled electron transfer reductions lead to the formation of a CoII-H intermediate with a dihydrogen phosphate ligand, and the reduction potentials for these two steps were calculated to be -0.58 V and -0.72 V, respectively. Subsequently, the H-H bond formation takes place via coupling of the CoII-H and the proton from the dihydrogen phosphate ligand. The total barrier was calculated to be 18.2 kcal mol 1 with an applied potential of -0.5 V, which can further decrease to only 11.2 kcal mol-1 with an applied potential of -0.8 V. When the phosphate is displaced by a water molecule, the total barrier for the dihydrogen formation increases by 7.3 kcal mol-1. For the iron catalyst, the overall mechanism is essentially the same; however, the first reduction (FeII/FeI, potential of -1.13 V) is likely the rate-limiting step. The calculated results are in good agreement with the experimental data, which showed an onset potential of -0.50 V for the cobalt complex and -1.03 V for the iron complex. PMID- 29192297 TI - Rapid spheroid clearing on a microfluidic chip. AB - Spheroids are three-dimensional (3D) cell cultures that aim to bridge the gap between the use of whole animals and cellular monolayers. Microfluidics is regarded as an enabling technology to actively control the chemical environment of 3D cell cultures. Although a wide variety of platforms have been developed to handle spheroid cultures, the development of analytical systems for spheroids remains a major challenge. In this study, we engineered a microfluidic large scale integration (mLSI) chip platform for tissue-clearing and imaging. To enable handling and culturing of spheroids on mLSI chips, with diameters within hundreds of microns, we first developed a general rapid prototyping procedure, which allows scaling up of the size of pneumatic membrane valves (PMV). The presented prototyping method makes use of milled poly(methylmethacrylate) (PMMA) molds for obtaining semi-circular microchannels with heights up to 750 MUm. Semi-circular channel profiles are required for the functioning of the commonly used PMVs in normally open configuration. Height limits to tens of microns for this channel profile on photolithographic molds have hampered the application of 3D tissue models on mLSI chips. The prototyping technique was applied to produce an mLSI chip for miniaturization, automation, and integration of the steps involved in the tissue clearing method CLARITY, including spheroid fixation, acrylamide hydrogel infiltration, temperature-initiated hydrogel polymerization, lipid extraction, and immuno-fluorescence staining of the mitochondrial protein COX-IV, and metabolic enzyme GAPDH. Precise fluidic control over the liquids in the spheroid culturing chambers allowed implementation of a local hydrogel polymerization reaction, exclusively within the spheroid tissue. Hydrogel embedded spheroids undergo swelling and shrinkage depending on the pH of the surrounding buffer solution. A pH-jump from 8.5 to 5.5 shrinks the hydrogel embedded spheroid volume by 108% with a rate constant of 0.36 min-1. The process is reversible upon increasing the pH, with the rate constant for the shrinkage being -0.12 min-1. Repetitive cycling of the pH induces an osmotic flow within the hydrogel-embedded spheroid. Thirty cycles, performed in a total time interval of 10 minutes on-chip, reduced the clearing time of a hydrogel-embedded spheroid (with a diameter of 200 MUm) from 14 days to 5 hours. Therefore, we developed a physicochemical method to decrease the clearing time of hydrogel-embedded tissues. While the osmotic pump mechanism is an alternative to electrophoretic forces for decreasing tissue clearing times, the integration of the CLARITY method on chip could enable high throughput imaging with 3D tissue cultures. PMID- 29192298 TI - The bond rupture force for sulfur chains calculated from quantum chemistry simulations and its relevance to the tensile strength of vulcanized rubber. AB - From quantum chemistry simulations using density functional theory, we obtain the total electronic energy of an eight-atom sulfur chain as its end-to-end distance is extended until S-S bond rupture occurs. We find that a sulfur chain can be extended by about 40% beyond its nominally straight conformation, where it experiences rupture at an end-to-end tension of about 1.5 nN. Using this rupture force as the chain failure limit in an explicit polymer network simulation model (EPnet), we predict the tensile failure stress for sulfur crosslinked (vulcanized) natural rubber. Quantitative agreement with published experimental data for the failure stress is obtained in these simulations if we assume that only about 30% of the sulfur chains produce viable network crosslinks. Surprisingly, we also find that the failure stress of a rubber network does not scale linearly with the chain failure force limit.

AB - New technologies that measure sparse molecular biomarkers from easily accessible bodily fluids (e.g. blood, urine, and saliva) are revolutionizing disease diagnostics and precision medicine. Microchip devices can measure more disease biomarkers with better sensitivity and specificity each year, but clinical interpretation of these biomarkers remains a challenge. Single biomarkers in 'liquid biopsy' often cannot accurately predict the state of a disease due to heterogeneity in phenotype and disease expression across individuals. To address this challenge, investigators are combining multiplexed measurements of different biomarkers that together define robust signatures for specific disease states. Machine learning is a useful tool to automatically discover and detect these signatures, especially as new technologies output increasing quantities of molecular data. In this paper, we review the state of the field of machine learning applied to molecular diagnostics and provide practical guidance to use this tool effectively and to avoid common pitfalls. PMID- 29192302 TI - Efficacy of Medicaid for Patients With Cancer in California. PMID- 29192303 TI - Association Between Ophthalmologist Age and Unsolicited Patient Complaints. AB - Importance: Understanding the distribution of patient complaints by physician age may provide insight into common patient concerns characteristic of early, middle, and late stages of careers in ophthalmology. Most previous studies of patient dissatisfaction have not addressed the association with physician age or controlled for other characteristics (eg, practice setting, subspecialty) that may contribute to the likelihood of patient complaints, unsafe care, and lawsuits. Objective: To assess the association between ophthalmologist age and the likelihood of generating unsolicited patient complaints (UPCs) among a cohort of ophthalmologists. Design, Setting, and Participants: Retrospective cohort study with variable duration of follow-up. The study assessed time to first complaint between 2002 and 2015 in 1342 attending ophthalmologists or neuro ophthalmologists who had graduated from medical school before 2010 and were affiliated with an organization that participates in Vanderbilt University Medical Center's Patient Advocacy Reporting System. Participants were stratified into 5 age bands and were followed up from the time of their employment to receipt of their first complaint. Trained coders categorized UPCs into 34 specific types under 6 major categories. Main Outcomes and Measures: Time to first recorded complaint. Multivariable Cox proportional hazards model was used to measure the association between time to first complaint and ophthalmologist age after adjustment for predetermined covariates. Results: The median physician age was 47 years, with 9% who were 71 years or older. The cohort was 74% male, 90% held MD degrees, and 73% practiced in academic medical centers. The mean follow-up period was 9.8 years. Ophthalmologists older than 70 years had the lowest complaint rate (0.71 per 1000 follow-up days vs 1.41, 1.84, 2.02, and 1.88 in descending order of age band). By 2000 days of follow-up (or within 5.5 years), the youngest group had an estimated UPC risk of 0.523. By 4000 days (>10 years), participants in the older than 70 years age band had an estimated risk of UPC of only 0.364. The 2 youngest age bands were associated with a statistically significant shorter time to first complaint. Compared with those aged 71 years or older, the risk of incurring a UPC for those aged 41 to 50 years was 1.73-fold higher (hazard ratio [HR], 1.73; 95% CI, 1.21-2.46; P = .002). Similarly, participants aged 31 to 40 years had a 2.36 times higher risk of incurring a UPC (HR, 2.36; 95% CI, 1.64-3.40; P < .001). Conclusions and Relevance: This study suggests that older ophthalmologists are less likely to receive UPCs than younger ones. Although limitations in the study design could affect the interpretation of these conclusions, the findings may have practical implications for patient safety, clinical education, and clinical practice management. PMID- 29192304 TI - Association of Hearing Loss and Otologic Outcomes With Fibrous Dysplasia. AB - Importance: Fibrous dysplasia (FD) and McCune-Albright syndrome (MAS) are rare bone and endocrine disorders in which expansile fibro-osseous lesions result in deformity, pain, and functional impairment. The effect of FD on hearing and otologic function has not been established. Objectives: To characterize audiologic and otologic manifestations in a large cohort of individuals with FD/MAS and to investigate potential mechanisms of hearing loss. Design, Setting, and Participants: In this natural history study, individuals with craniofacial FD seen at a clinical research center underwent clinical, biochemical, computed tomographic, audiologic, and otolaryngologic evaluations. Main Outcomes and Measures: Clinical and radiologic features associated with hearing loss and otologic disease were evaluated. Conductive hearing loss was hypothesized to be associated with narrowing of the external auditory canal (EAC), FD involving the epitympanum, and FD crowding the ossicular chain. Sensorineural hearing loss was hypothesized to be associated with FD affecting the internal auditory canal (IAC) and otic capsule. Results: Of the 130 study participants with craniofacial FD who were evaluated, 116 (89.2%) had FD that involved the temporal bone (median age, 19.6 years; range, 4.6-80.3 years; 64 female [55.2%]), whereas 14 (10.8%) had craniofacial FD that did not involve the temporal bone. Of the 183 ears with temporal bone FD, hearing loss was identified in 41 ears (22.4%) and was conductive in 27 (65.9%), sensorineural in 12 (29.3%), and mixed in 2 (4.9%). Hearing loss was mild and nonprogressive in most participants. Whereas EACs were narrower in ears with FD (mean difference [MD], 0.33 mm; 95% CI, 0.11-0.55 mm), this finding was associated with conductive hearing loss in only 4 participants. Fibrous dysplasia crowding of the ossicles was associated with conductive hearing loss (odds ratio [OR], 5.0; 95% CI, 2.1-11.6). The IAC length was not different between ears with and without FD (MD, -0.37; 95% CI, -0.95 to 0.211); however, canals were elongated in ears with sensorineural hearing loss (MD, -1.33; 95% CI, -2.60 to -0.07). Otic capsule involvement was noted in only 4 participants, 2 of whom had sensorineural hearing loss. Both MAS-associated growth hormone excess (OR, 3.1; 95% CI, 1.3-7.5) and neonatal hypercortisolism (OR, 11; 95% CI, 2.5-55) were associated with an increased risk of hearing loss . Conclusions and Relevance: Hearing loss in craniofacial FD is common and mild to moderate in most individuals. It typically arises from FD crowding of the ossicular chain and elongation of the IAC, whereas EAC stenosis and otic capsule invasion are less common causes. Individuals with craniofacial FD should undergo otolaryngologic evaluation and monitoring, including assessment to identify those with high-risk features. PMID- 29192305 TI - Association of Quantitative Metastatic Lymph Node Burden With Survival in Hypopharyngeal and Laryngeal Cancer. AB - Importance: Nodal staging for laryngohypopharyngeal cancers is based primarily on size and laterality, with less value placed on absolute number of metastatic lymph nodes (LNs). We are aware of no studies to date that have specifically addressed the prognostic effect of quantitative nodal burden in larynx or hypopharynx malignancies. Objective: To assess the independent impact of quantitative metastatic LN burden on mortality risk. Design, Setting, and Participants: Univariate and multivariable models were constructed to evaluate the association between patients' number of metastatic LNs and their survival, adjusting for factors such as nodal size, laterality, extranodal extension, margin status, and adjuvant treatment. Participants were patients with squamous cell carcinoma of the larynx or hypopharynx undergoing upfront surgical resection for curative intent at a US hospital between 2004 and 2013, as identified in the National Cancer Database. A neck dissection of a minimum of 10 LNs was required. Main Outcomes and Measures: Overall survival. Results: Overall, 8351 cases were included (mean [SD] age, 61 [10.1] years; 6499 men [77.8%]; 4710 patients with metastatic LNs and 3641 with no metastatic LNs). Mortality risk escalated continuously without plateau as number of metastatic nodes increased, with the hazard per node (hazard ratio [HR], 1.19; 95% CI, 1.16-1.23; P < .001) most pronounced up to 5 positive LNs. Extranodal extension was also associated with increased mortality (HR, 1.34; 95% CI, 1.13-1.59; P < .001). Increasing number of nodes examined was associated with improved survival, albeit to a lesser degree (per 10 LNs: HR, 0.97; 95% CI, 0.96-0.98; P < .001) and without a detectable change point. Other nodal factors, including nodal size, contralateral LN involvement (TNM stage N2c), and lower LN involvement (levels 4-5), were not associated with mortality in multivariable models when accounting for number of positive LNs. A novel, parsimonious nodal staging system derived by recursive partitioning analysis exhibited greater concordance with survival than the TNM staging system outlined in the American Joint Committee on Cancer's AJCC Staging Manual, 8th edition. Conclusions and Relevance: The number of metastatic nodes is a predominant independent factor associated with mortality in hypopharyngeal and laryngeal cancers. Moreover, standard nodal staging factors like LN size and contralaterality have no independent prognostic value when accounting for positive LN number. Deeper integration of quantitative metastatic nodal disease may simplify staging and better triage the need for adjuvant therapy. PMID- 29192306 TI - Asymptomatic Septal Mass. PMID- 29192307 TI - Trends in Cancer Survival by Health Insurance Status in California From 1997 to 2014. AB - Importance: There have been substantial improvements in the early detection, treatment, and survival from cancer in the United States, but it is not clear to what extent patients with different types of health insurance have benefitted from these advancements. Objective: To examine trends in cancer survival by health insurance status from January 1997 to December 2014. Design, Setting, and Participants: California Cancer Registry (a statewide cancer surveillance system) data were used to estimate population-based survival by health insurance status in 3 calendar periods: January 1997 to December 2002, January 2003 to December 2008, and January 2009 to December 2014 with follow-up through 2014. Overall, 1 149 891 patients diagnosed with breast, prostate, colorectal, or lung cancer, or melanoma in California were included in the study. Main Outcomes and Measures: Five-year all-cause and cancer-specific survival probabilities by insurance category and calendar period for each cancer site and sex; hazard ratios (HRs) and 95% CIs for each insurance category (none, Medicare, other public) compared with private insurance in each calendar period. Results: According to data from 1 149 891 patients diagnosed with breast, prostate, colorectal, or lung cancer, or melanoma gathered from the California Cancer Registry, improvements in survival were almost exclusively limited to patients with private or Medicare insurance. For patients with other public or no insurance, survival was largely unchanged or declined. Relative to privately insured patients, cancer-specific mortality was higher in uninsured patients for all cancers except prostate, and disparities were largest from 2009 to 2014 for breast (HR, 1.72; 95% CI, 1.45-2.03), lung (men: HR, 1.18; 95% CI, 1.06-1.31 and women: HR, 1.32; 95% CI, 1.15-1.50), and colorectal cancer (women: HR, 1.30; 95% CI, 1.05-1.62). Mortality was also higher for patients with other public insurance for all cancers except lung, and disparities were largest from 2009 to 2014 for breast (HR, 1.25; 95% CI, 1.17 1.34), prostate (HR, 1.17; 95% CI, 1.04-1.31), and colorectal cancer (men: HR, 1.16; 95% CI, 1.08-1.23 and women: HR, 1.11; 95% CI, 1.03-1.20). Conclusions and Relevance: After accounting for patient and clinical characteristics, survival disparities for men with prostate cancer and women with lung or colorectal cancer increased significantly over time, reflecting a lack of improvement in survival for patients with other public or no insurance. To mitigate these growing disparities, all patients with cancer need access to health insurance that covers all the necessary elements of health care, from prevention and early detection to timely treatment according to clinical guidelines.

PMID- 29192313 TI - The shape of novel objects contributes to shared impressions. AB - How do people share impressions of novel objects, and is this even possible? We tested whether the shape of novel 3-D objects can lead to similar impressions across people. To do this, we introduced a technique for manipulating highly complex shapes and measured four types of evaluative impressions (approachable, dangerous, beautiful, likable). Because relatively little is understood regarding how people form impressions of novel objects, we first sought to confirm the reliability of this behavior by examining how similar impressions are for an individual asked to re-evaluate the stimuli (i.e., impression consistency). To situate the magnitude of reliability, we compared novel objects to faces-familiar and extensively studied stimuli. Impression consistency was always present for both types of stimuli and comparable across all evaluations. Second, and more importantly, we tested how similar impressions are across people (i.e., impression consensus). Impression consensus was always present for faces, but not always for novel objects. In Study 2 we examined a greater diversity of shapes and replicated the findings of Study 1 for novel objects. The findings suggest that impression consensus for novel objects only emerges when certain types of shapes and evaluations map together. When such mapping is possible, impressions are isomorphic with the parametrized shapes. PMID- 29192312 TI - Association of Lymph Node Density With Survival of Patients With Papillary Thyroid Cancer. AB - Importance: Lymph node metastases are common in papillary thyroid cancer (PTC), yet the impact of nodal metastases on survival remains unclear. Lymph node density (LND) is the ratio between the number of positive lymph nodes excised and the total number of excised lymph nodes. Lymph node density has been suggested as a prognostic factor in many types of cancer. Objective: To evaluate the prognostic role of LND in PTC. Design, Setting, and Participants: This cohort study reviewed medical records of patients with PTC who were treated at the University of Texas MD Anderson Cancer Center between January 1, 2000, and December 31, 2015. Survival and recurrence outcomes were calculated by using the Kaplan-Meier method. Significant variables on univariate analysis were subjected to a Cox proportional hazards regression multivariate model. Main Outcomes and Measures: Primary study outcome was disease-specific survival (DSS); other measurements included overall survival (OS). Results: The study cohort included data for 2542 patients (1801 [71%] male; median age, 48 years [range, 18-97 years]) with a median follow-up of 55 months (range, 4-192 months). The 10-year disease-specific survival rate was 98% for patients with LND of 0.19 or less, compared with 90% for those with LND greater than 0.19 (effect size, 8%; 95% CI, 4%-15%). The 10-year overall survival was 87% for patients with LND of 0.19 or less, compared with 79% for patients with LND greater than 0.19 (effect size, 8%; 95% CI, 3%-15%). Multivariable analysis revealed that LND greater than 0.19 was independently associated with an adverse DSS (hazard ratio [HR], 4.11; 95% CI, 2.11-8.97) and OS (HR, 1.96; 95% CI, 1.24-4.11). Subgroup analysis of patients with 18 or more lymph nodes analyzed revealed that LND greater than 0.19 remained a significant marker for DSS (HR, 2.94; 95% CI, 1.36-9.81) and OS (HR, 2.26; 95% CI, 1.12-5.34). Incorporating LND into the current American Joint Committee on Cancer staging system successfully stratified risk groups compared with the traditional TNM staging system. Conclusions and Relevance: This single-institute study demonstrates the reproducibility of LND as a predictor of outcomes in PTC. Lymph node density can potentially assist in identifying patients with poorer survival who may benefit from more aggressive adjuvant therapy. PMID- 29192314 TI - Contour junctions defined by dynamic image deformations enhance perceptual transparency. AB - The majority of work on the perception of transparency has focused on static images with luminance-defined contour junctions, but recent work has shown that dynamic image sequences with dynamic image deformations also provide information about transparency. The present study demonstrates that when part of a static image is dynamically deformed, contour junctions at which deforming and nondeforming contours are connected facilitate the deformation-based perception of a transparent layer. We found that the impression of a transparent layer was stronger when a dynamically deforming area was adjacent to static nondeforming areas than when presented alone. When contour junctions were not formed at the dynamic-static boundaries, however, the impression of a transparent layer was not facilitated by the presence of static surrounding areas. The effect of the deformation-defined junctions was attenuated when the spatial pattern of luminance contrast at the junctions was inconsistent with the perceived transparency related to luminance contrast, while the effect did not change when the spatial luminance pattern was consistent with it. In addition, the results showed that contour completions across the junctions were required for the perception of a transparent layer. These results indicate that deformation defined junctions that involve contour completion between deforming and nondeforming regions enhance the perception of a transparent layer, and that the deformation-based perceptual transparency can be promoted by the simultaneous presence of appropriately configured luminance and contrast-other features that can also by themselves produce the sensation of perceiving transparency. PMID- 29192315 TI - Clinical Factors Associated With Reoperation and Prolonged Length of Stay in Free Tissue Transfer to Oncologic Head and Neck Defects. AB - Importance: Prolonged hospitalization and reoperation after free tissue transfer may be associated with certain clinical factors. Objective: To determine patient and surgical factors associated with length of stay (LOS) and reoperation following surgical procedures for malignant neoplasm of the head and neck involving microvascular free tissue transfer reconstruction. Design, Setting, and Participants: This was a retrospective review of American College of Surgeons National Surgical Quality Improvement Program data from 2012 to 2014 using International Classification of Diseases, Ninth Revision (ICD-9), codes for malignant neoplasms of the head and neck. Multivariable logistic regression modeling was used to examine correlation of patient and surgical variables with reoperation and LOS. The national retrospective database included outcomes from community and academic participant hospitals (517 member institutions in 2014). A total of 1115 cases of head and neck malignant neoplasm ablation with microvascular free tissue transfer flap were reviewed retrospectively. Main Outcomes and Measures: Incidence of reoperation within 30 days of index operation and hospitalization equal to or longer than 13.0 days, which is equal to being in the top quartile for duration of stay. Results: Of the 1115 patients, 370 (33.2) were female, and the mean (SD) age was 66.8 (3.9) years. Predictors of prolonged length of stay included return to the operating room (odds ratio [OR], 4.8; 95% CI, 3.3-6.9), smoking (OR, 2.1; 95% CI, 1.5-3.1), clean-contaminated wound (OR, 2.2; 95% CI, 1.3-4.0), bony flap (OR, 1.8; 95% CI, 1.2-2.8), age (OR, 1.5; 95% CI, 1.2-1.7), and operative time (OR, 1.2; 95% CI, 1.1-1.3). Reoperation occurred 298 times for 225 patients (20.2%). Mean (SD) time to reoperation was 8.0 (7.7) days, with 180 (80%) occurring before discharge from the primary operation. The most common indications for reoperation were neck exploration (37 [12.4%]) or incision and drainage of neck (35 [11.7%]). Conclusions and Relevance: American College of Surgeons National Surgical Quality Improvement Program data allow for large database analysis of free flap transfer to the head and neck. The data herein provide information to help guide surgeons on which patients will require longer stay in hospital and the most common reasons for return to the operating room. Wound class of index operation, subsequent wound-related complications, and long duration of the index operation were the primary drivers of increased risk for reoperation and, therefore, prolonged hospitalization. These same factors were also associated with prolonged hospitalization without reoperation. Level of Evidence: NA.

PMID- 29192318 TI - The Influence of Target and Masker Characteristics on Infants' and Adults' Detection of Speech. AB - Purpose: Several investigators have compared infants' detection of speech in speech and nonspeech maskers to evaluate developmental differences in masking. Such comparisons have produced contradictory results, possibly because each investigation used different stimuli. The current study examined target and masker effects on infants' and adults' detection of speech. Method: An observer based procedure was used to compare infants' and adults' detection of the vowel /v/ and the word "baby" in a 2-talker speech masker and matched speech-spectrum noise. The measure of performance was d'. A total of 43 7-month-old infants and 41 young adults were randomly assigned to 1 target-masker combination condition, and mean performance was compared across conditions at each age. Results: Adults' detection was influenced by an interaction between the target and the masker: Adults detected the vowel better in the 2-talker masker than in speech-spectrum noise but detected the word equally well in the 2 maskers. In contrast, infants detected both targets better in speech-spectrum noise than in the 2-talker masker. Conclusions: The relative effects of the masker on target detection by infants and adults depend on the target to be detected. Thus, conclusions drawn about differences between infants and adults in the mechanisms responsible for masking will depend on the stimuli. Standardization of speech stimuli in developmental research would help clarify the nature of infants' segregation difficulties. Supplemental Material: https://doi.org/10.23641/asha.5613139.

PMID- 29192320 TI - Combined SN-38 and gefitinib treatment promotes CD44 degradation in head and neck squamous cell carcinoma cells. AB - The aim of the present study was to search for an effective regimen among existing chemotherapies for head and neck squamous cell carcinoma (HNSCC). Among the tested drugs, we focused on combined SN-38, which is the active metabolite produced from irinotecan hydrochloride - a type I DNA topoisomerase inhibitor - after it is metabolized by carboxylesterase in the liver and gefitinib, an EGFR tyrosine kinase inhibitor treatment, based on the ability of this combination to inhibit HNSCC cell growth. Contrary to our expectation, in vivo, there was no significant difference in tumor growth suppression between gefitinib-only treatment and gefitinib plus SN-38. However, when tumor measurements were continued after treatment ceased, we found that several tumors showed renewed growth in the gefitinib-only group. The tumors that resumed growing after treatment showed increased CD44 expression compared with tumors from the combined treatment group. Next, we investigated the mechanism whereby SN-38 and gefitinib inhibited CD44 expression in vitro. These studies revealed that the combined treatment promoted lysosomal degradation of CD44. The present study revealed that combined gefitinib and SN-38 treatment inhibits CD44 expression by promoting its lysosomal degradation in HNSCC cells. However, it is still unclear whether inhibition of CD44 expression in HNSCC cells can directly suppress tumor regrowth after therapy. Thus, it may be necessary to elucidate the relationship between the effects of these chemotherapeutic agents on CD44 expression and tumor recurrence/metastasis in future studies. PMID- 29192321 TI - miR-106b-5p promotes cell cycle progression of malignant melanoma by targeting PTEN. AB - This study investigated how miR-106b-5p/PTEN signaling affects the cell cycle of malignant melanoma (MM) cells. miR-106b-5p mRNA was identified with qRT-PCR. Through transient transfection, miR-106b-5p or PTEN was upregulated and downregulated in MM cells. With such transfected cells, MTT assay, colony formation assay and flow cytometry were carried out to investigate the role of miR-106b-5p in cell cycle progression after the transfected cells were treated with reverse-regulation of miR-106b-5p or PTEN. Western blot analysis was used to quantify all proteins, and a luciferase reporter assay was carried out to validate miR-106b-5p targeting PTEN. miR-106b-5p mRNA was overexpressed in MM tissues and cell lines. MM cells with upregulated miR-106b-5p presented faster growth and shorter cell cycles, while those with knockdown of miR-106b-5p presented the opposite trend. PTEN was subject to post-transcriptional regulation of miR-106b-5p. Based on such a finding, further exploration was carried out to investigate the interaction between cyclin D1 and P27Kip1, with the finding that miR-106b-5p can stimulate cyclin D1 and suppress P27Kip1 via the Akt/ERK pathway. The results of this study suggest that miR-106b-5p may be a promoter in MM progression, possibly by targeting PTEN and thus regulating the downstream cell cycle-related proteins and Akt/ERK pathway. PMID- 29192322 TI - omega3-polyunsaturated fatty acids induce cell death through apoptosis and autophagy in glioblastoma cells: In vitro and in vivo. AB - Among brain tumors, glioblastoma (GBM) is the most aggressive type and is associated with the lowest patient survival rate. Numerous lines of evidence have established that omega-3-polyunsaturated fatty acids (omega3-PUFAs) have potential for the prevention and therapy of several types of cancers. Docosahexaenoic acid (DHA), an omega3-PUFA, was reported to inhibit growth and induce apoptotic and autophagic cell death in several cancer cell lines; however, its effects on GBM cells are still unknown. in the present study, we examined the cytotoxic effect of DHA on the GBM cell lines, D54MG, U87MG, U251MG and GL261. Treatment of GBM cells with DHA induced PARP cleavage, increased the population of sub-G1 cells, and increased the number of TUNEL-positive cells, which are all indicative of apoptosis. Furthermore, treatment of GBM cells with DHA resulted in a significant increase in autophagic activity, as revealed by increased LC3-II levels, GFP-LC3 puncta, and autophagic flux activation, accompanied by activation of 5'-AMP-activated protein kinase (AMPK) and decreases in phosphorylated Akt (p AktSer473) levels and mTOR activity. In vivo, endogenous expression of Caenorhabditis elegans omega3-desaturase, which converts omega6-PUFAs to omega3 PUFAs, in fat-1 transgenic mice yielded a significant decrease in tumor volume following subcutaneous injection of mouse glioma cells (GL261), when compared with wild-type mice. TUNEL-positive cell numbers and LC3-II levels were elevated in tumor tissue from the fat-1 transgenic mice compared with tumor tissue from the wild-type mice. In addition, p-Akt levels were decreased and p-AMPK levels were increased in tumor tissue from the fat-1 transgenic mice. These results indicate that omega3-PUFAs induce cell death through apoptosis and autophagy in GBM cells; thus, it may be possible to use omega3-PUFAs as chemopreventive and therapeutic agents for GBM. PMID- 29192323 TI - Significant inhibition of infantile hemangioma growth by sustained delivery of urea from liposomes-in-microspheres. AB - Infantile hemangioma (IH) is a benign pediatric tumor, and rapid growth of IH can result in serious morbidity and even mortality. Only one drug HemangeolTM (propranolol hydrochloride oral solution) has been approved for the treatment of IH, whereas patients suffer from its adverse effects and high frequency of administration. We have used urea, an organic compound and a normal body metabolite, in the treatment of IH for 20 years, and demonstrated that urea is an effective and well-tolerated treatment for IH. To reduce the daily administration of urea, we firstly utilized urea-loaded liposomes-in-microspheres (ULIM) as a novel topical controlled release system to realize the sustained release of urea. ULIM were fabricated from the encapsulation of urea-loaded liposomes in poly(lactic-co-glycolic acid)-b-poly(ethylene glycol)-b-poly(lactic-co-glycolic acid) microspheres. The characteristics, activity and mechanism against IH of ULIM were examined in vitro and in vivo. ULIM were of a desired particle size (~62.4 um), drug encapsulation efficiency (~51.5%) and sustained drug release for 40 days. ULIM inhibited the proliferation of hemangioma endothelia cells (HemECs) and expression of vascular endothelial growth factor-A in HemECs. The therapeutic effect of ULIM in IH was better than propranolol, urea, urea-loaded liposomes and urea-loaded microspheres in vivo, as reflected by markedly decreased hemangioma weight, volume and microvessel density. None of the treated mice showed behavioral changes, severe side-effects and weight loss. Our results suggest that use of ULIM is a potential and safe approach with which to locally and efficiently deliver urea to hemangioma, and is a promising alternative to propranolol in the treatment of IH. PMID- 29192324 TI - A novel mechanism of neovascularization in peritoneal dissemination via cancer associated mesothelial cells affected by TGF-beta derived from ovarian cancer. AB - Epithelial ovarian cancer (EOC) is believed to cause peritoneum dissemination through microenvironmental cell-to-cell communication between the tumor and mesothelium, leading to the further acquisition of progressive and metastatic potentials. In the present study, we aimed to determine the role of cancer associated mesothelial cells (CAMCs) in the promotion of tumor neovascularization and vascular permeability via enhanced vascular endothelial growth factor (VEGF) production. We examined whether a characteristic morphological change in human peritoneal mesothelial cells (HPMCs) was observed in the presence of malignant ascites and tumor-derived TGF-beta. We focused on the enhanced production of VEGF in CAMCs and its crucial role in endothelial migration and tube formation. Normal HPMCs showed an epithelial morphology with a cobblestone appearance. When HPMCs were co-cultured with malignant ascites from patients with advanced EOC, a dramatic morphologic change was noted from an epithelioid pattern to an alpha-SMA positive fibroblastic, mesenchymal pattern. Additionally, we found that EOC derived TGF-beta induced typical EMT-like morphological alteration in HPMCs, which was associated with CAMCs. We further discovered that CAMCs play a crucial role in the enhanced migration and tube formation of endothelial cells by the promotion of VEGF production. In conclusion, our findings indicate the possible involvement of CAMCs in the neovascularization of EOC and enhancement of vascular permeability, resulting in the formation of malignant ascites. The novel mechanism of CAMCs as a facilitator of EOC progression is displayed by microenvironmental cell-to-cell communication between EOC and the mesothelium. PMID- 29192325 TI - Downregulation of microRNA-1274a induces cell apoptosis through regulation of BMPR1B in clear cell renal cell carcinoma. AB - Our previous studies of the microRNA (miRNA) expression signature in clear cell renal cell carcinoma (ccRCC) indicated that miRNA-1274a (miR-1274a) was significantly upregulated in clinical specimens, suggesting that miR-1274a may act as an oncogenic miRNA in ccRCC. The aim of this study was to investigate the functional roles of miR-1274a and identify downstream tumor-suppressive targets regulated by miR-1274a in ccRCC cells. Functional studies of miR-1274a were carried out by anti-miRNA to investigate cell proliferation and apoptosis using the A498, ACHN and Caki1 ccRCC cell lines. Suppression of miR-1274a significantly inhibited cancer cell proliferation and induced apoptosis in the ccRCC cells. Gene expression data combined with in silico analysis and luciferase reporter assays demonstrated that bone morphogenetic protein receptor type 1B (BMPR1B) was directly regulated by miR-1274a. Moreover, TCGA database as well as immunohistochemistry demonstrated low expression of BMPR1B in ccRCC clinical specimens compared to that in normal kidney tissues. We conclude that loss of oncogenic miR-1274a reduced cancer cell proliferation and induced apoptosis in ccRCC through targeting BMPR1B. Our data revealing molecular pathways and a target gene regulated by oncogenic miR-1274a provide new insight into the potential mechanisms of ccRCC oncogenesis. PMID- 29192326 TI - EPS8 regulates proliferation, apoptosis and chemosensitivity in BCR-ABL positive cells via the BCR-ABL/PI3K/AKT/mTOR pathway. AB - Although the introduction of tyrosine kinase inhibitors greatly improved the survival of patients with chronic myeloid leukemia (CML), drug resistance remains a problem. Thus, mechanism-based novel therapeutic targets warrant exploration. Recently, epidermal growth factor receptor kinase substrate 8 (EPS8), which has been identified as an oncogene and plays an important role in a broad spectrum of solid tumours, was reported to be related to poor prognosis or chemoresistance in acute leukemia patients. However, its role in CML remains unclear. In the present study, using q-RT-PCR, we demonstrated that CML patients expressed a higher level of EPS8 mRNA in bone marrow mononuclear cells than healthy controls. Then, to determine the effect of EPS8 on the biological functions of CML cells, EPS8 expression was knocked down in the human CML cell line K562. Reduced proliferation, increased apoptosis, impaired adhesion and migration were observed in K562 cells after EPS8 silencing. Notably, attenuation of EPS8 increased chemosensitivity both in imatinib-sensitive K562 cells and in the imatinib resistant murine BCR-ABL+ 32D-p210BCR/ABL-T315I cells. Mechanistically, knockdown of EPS8 downregulated p-BCR/ABL and its downstream AKT/mTOR signalling pathway. Finally, knockdown of EPS8 attenuated K562 cell proliferation in BALB/c nude mice. These data indicated that EPS8 regulated the proliferation, apoptosis and chemosensitivity in BCR-ABL positive cells via the BCR-ABL/PI3K/AKT/mTOR pathway. Targeting EPS8 alone or combined with a tyrosine kinase inhibitor may be a promising alternative therapeutic strategy. PMID- 29192327 TI - Characterization of etoposide- and cisplatin-chemoresistant retinoblastoma cell lines. AB - Retinoblastoma (RB) is the most common malignant intraocular tumor in early childhood. Imminent chemotherapy resistance diminishes the clinical-therapeutic options and emphasizes the necessity for new therapeutic approaches. The present study aimed at characterizing and comparing etoposide and cisplatin-resistant human RB cell lines with regard to changes in proliferation and apoptosis levels, anchorage independent growth behavior in vitro as well as tumor formation capacity in vivo. The proliferation rates were significantly increased in the etoposide-resistant RB cell lines Y-79, WERI-Rb1 and RB-355 reflecting significantly higher growth kinetics compared to the parental controls. In line with these findings in in vivo chicken chorioallantoic (CAM) assays, etoposide resistant cell lines generated significantly increased numbers of tumors with higher tumor weights compared to their parental counterparts. In contrast to etoposide, the cisplatin-resistant RB cell lines Y-79, WERI-Rb1 and RB-355 displayed significantly increased apoptosis rates and reduced proliferation rates resulting in significantly decreased growth kinetics. Tumor formation capacity of cisplatin-resistant cell lines did not significantly change, and in comparison with parental controls cisplatin-resistant Y-79 cells displayed significantly reduced tumor weight. Soft agarose assays indicated that anchorage-independent growth of all chemotherapy-resistant cell lines analyzed was significantly decreased. Summarizing, one can state that etoposide-resistant RB cells behave more aggressively than the tumor cells of origin and potentially represent a risk factor for local relapse, while cisplatin-resistant cells show a significantly decreased tumorigenic potential. PMID- 29192328 TI - CRISPR/Cas9-mediated knockout of PiSSK1 reveals essential role of S-locus F-box protein-containing SCF complexes in recognition of non-self S-RNases during cross compatible pollination in self-incompatible Petunia inflata. AB - KEY MESSAGE: Function of Petunia PiSSK1. Self-incompatibility (SI), an inbreeding preventing mechanism, is regulated in Petunia inflata by the polymorphic S-locus, which houses multiple pollen-specific S-locus F-box (SLF) genes and a single pistil-specific S-RNase gene. S 2-haplotype and S 3-haplotype possess the same 17 polymorphic SLF genes (named SLF1 to SLF17), and each SLF protein produced in pollen is assembled into an SCF (Skp1-Cullin1-F-box) E3 ubiquitin ligase complex. A complete suite of SLF proteins is thought to collectively interact with all non self S-RNases to mediate their ubiquitination and degradation by the 26S proteasome, allowing cross-compatible pollination. For each SCFSLF complex, the Cullin1 subunit (named PiCUL1-P) and Skp1 subunit (named PiSSK1), like the F-box protein subunits (SLFs), are pollen-specific, raising the possibility that they also evolved specifically to function in SI. Here we used CRISPR/Cas9-meditated genome editing to generate frame-shift indel mutations in PiSSK1 and examined the SI behavior of a T 0 plant (S 2 S 3) with biallelic mutations in the pollen genome and two progeny plants (S 2 S 2) each homozygous for one of the indel alleles and not carrying the Cas9-containing T-DNA. Their pollen was completely incompatible with pistils of seven otherwise-compatible S-genotypes, but fully compatible with pistils of an S 3 S 3 transgenic plant in which production of S3 RNase was completely suppressed by an antisense S 3-RNase gene, and with pistils of immature flower buds, which produce little S-RNase. These results suggest that PiSSK1 specifically functions in SI and support the hypothesis that SLF containing SCF complexes are essential for compatible pollination. PMID- 29192329 TI - Oral curcumin for radiation dermatitis: a URCC NCORP study of 686 breast cancer patients. AB - PURPOSE: Despite advances in medical technology, radiation dermatitis occurs in 95% of patients receiving radiation therapy (RT) for cancer. Currently, there is no standard and effective treatment for the prevention or control of radiation dermatitis. The goal of the study was to determine the efficacy of oral curcumin, one of the biologically active components in turmeric, at reducing radiation dermatitis severity (RDS) at the end of RT, using the RDS scale, compared to placebo. METHODS: This was a multisite, randomized, double-blinded, placebo controlled trial of 686 breast cancer patients. Patients took four 500-mg capsules of placebo or curcumin three times daily throughout their prescribed course of RT until 1 week post-RT. RESULTS: A total of 686 patients were included in the final analyses (87.5% white females, mean age = 58). Linear mixed-model analyses demonstrated that curcumin did not reduce radiation dermatitis severity at the end of RT compared to placebo (B (95% CI) = 0.044 (- 0.101, 0.188), p = 0.552). Fewer curcumin patients with RDS > 3.0 suggested a trend toward reduced severity (7.4 vs. 12.9%, p = 0.082). Patient-reported changes in pain, symptoms, and quality of life were not statistically significant between arms. CONCLUSIONS: Oral curcumin did not significantly reduce radiation dermatitis severity compared to placebo. The skin rating variation and broad eligibility criteria could not account for the undetectable therapeutic effect. An objective measure for radiation dermatitis severity and further exploration for an effective treatment for radiation dermatitis is warranted. PMID- 29192330 TI - The role of ocelli in cockroach optomotor performance. AB - Insect ocelli are relatively simple eyes that have been assigned various functions not related to pictorial vision. In some species they function as sensors of ambient light intensity, from which information is relayed to various parts of the nervous system, e.g., for the control of circadian rhythms. In this work we have investigated the possibility that the ocellar light stimulation changes the properties of the optomotor performance of the cockroach Periplaneta americana. We used a virtual reality environment where a panoramic moving image is presented to the cockroach while its movements are recorded with a trackball. Previously we have shown that the optomotor reaction of the cockroach persists down to the intensity of moonless night sky, equivalent to less than 0.1 photons/s being absorbed by each compound eye photoreceptor. By occluding the compound eyes, the ocelli, or both, we show that the ocellar stimulation can change the intensity dependence of the optomotor reaction, indicating involvement of the ocellar visual system in the information processing of movement. We also measured the cuticular transmission, which, although relatively large, is unlikely to contribute profoundly to ocellar function, but may be significant in determining the mean activity level of completely blinded cockroaches. PMID- 29192331 TI - Are neutrophil, platelet and eosinophil-to-lymphocyte ratio and red blood cell distribution width can be used for nasal polyposis? AB - INTRODUCTION: The aim of this study is to explore the relationship of neutrophil, platelet and eosinophil-to-lymphocyte ratios and red blood cell distribution width values with nasal polyposis, and whether this could be a predictive parameter that can be used for the severity and recurrence risk of the disease. METHOD: Neutrophil/lymphocyte, platelet/lymphocyte, eosinophil/lymphocyte ratios and red blood cell distribution width values were compared between nasal polyposis patients who were reviewed in a retrospective manner and the control group comparable for age and sex. Moreover, the nasal polyposis group was grouped for nasal polyposis severity and recurrence, and these subgroups were statistically compared, too. RESULTS: When the nasal polyposis patient group and the control group are compared, no statistically significant difference was found between two groups except for eosinophil/lymphocyte ratio. While only the difference between nasal polyposis severity and eosinophil/lymphocyte ratio is statistically significant, there was no parameter with statistically significant difference for recurrence. CONCLUSION: We think that caution should be exercised when using these new hematological parameters which can be affected by many factors for the presence, severity and recurrence risk of nasal polyposis, and literature data should be proven by conducting different and objective studies on this subject.

PMID- 29192334 TI - Putative Independent Evolutionary Reversals from Genotypic to Temperature Dependent Sex Determination are Associated with Accelerated Evolution of Sex Determining Genes in Turtles. AB - The evolutionary lability of sex-determining mechanisms across the tree of life is well recognized, yet the extent of molecular changes that accompany these repeated transitions remain obscure. Most turtles retain the ancestral temperature-dependent sex determination (TSD) from which multiple transitions to genotypic sex determination (GSD) occurred independently, and two contrasting hypotheses posit the existence or absence of reversals back to TSD. Here we examined the molecular evolution of the coding regions of a set of gene regulators involved in gonadal development in turtles and several other vertebrates. We found slower molecular evolution in turtles and crocodilians compared to other vertebrates, but an acceleration in Trionychia turtles and at some phylogenetic branches demarcating major taxonomic diversification events. Of all gene classes examined, hormone signaling genes, and Srd5a1 in particular, evolve faster in many lineages and especially in turtles. Our data show that sex linked genes do not follow a ubiquitous nor uniform pattern of molecular evolution. We then evaluated turtle nucleotide and protein evolution under two evolutionary hypotheses with or without GSD-to-TSD reversals, and found that when GSD-to-TSD reversals are considered, all transitional branches irrespective of direction, exhibit accelerated molecular evolution of nucleotide sequences, while GSD-to-TSD transitional branches also show acceleration in protein evolution. Significant changes in predicted secondary structure that may affect protein function were identified in three genes that exhibited hastened evolution in turtles compared to other vertebrates or in transitional versus non-transitional branches within turtles, rendering them candidates for a key role during SDM evolution in turtles. PMID- 29192335 TI - Diversity and Cyclical Seasonal Transitions in the Bacterial Community in a Large and Deep Perialpine Lake. AB - High-throughput sequencing (HTS) was used to analyze the seasonal variations in the bacterioplankton community composition (BCC) in the euphotic layer of a large and deep lake south of the Alps (Lake Garda). The BCC was analyzed throughout two annual cycles by monthly samplings using the amplification and sequencing of the V3-V4 hypervariable region of the 16S rRNA gene by the MiSeq Illumina platform. The dominant and most diverse bacterioplankton phyla were among the more frequently reported in freshwater ecosystems, including the Proteobacteria, Cyanobacteria, Bacteroidetes, Verrucomicrobia, Actinobacteria, and Planctomycetes. As a distinctive feature, the development of the BCC showed a cyclical temporal pattern in the two analyzed years and throughout the euphotic layer. The recurring temporal development was controlled by the strong seasonality in water temperature and thermal stratification, and by cyclical temporal changes in nutrients and, possibly, by the remarkable annual cyclical development of cyanobacteria and eukaryotic phytoplankton hosting bacterioplankton that characterizes Lake Garda. Further downstream analyses of operational taxonomic units associated to cyanobacteria allowed confirming the presence of the most abundant taxa previously identified by microscopy and/or phylogenetic analyses, as well as the presence of other small Synechococcales/Chroococcales and rare Nostocales never identified so far in the deep lakes south of the Alps. The implications of the high diversity and strong seasonality are relevant, opening perspectives for the definition of common and discriminating patterns characterizing the temporal and spatial distribution in the BCC, and for the application of the new sequencing technologies in the monitoring of water quality in large and deep lakes.

Sporocysts were obtained from intestinal tracts of 8 of 13 D. aurita trapped in Rio de Janeiro state, Brazil, and were orally inoculated into Melopsittacus undulatus and Balb/c nude Mus musculus. Portions of organs and muscles were processed for histology, immunohistochemistry, transmission electron microscopy (TEM), and PCR using primers JNB 33/54, and ITS. Amplification products were subjected to RFLP using DraI and HinfI. Some birds were euthanized 6, 7, 13, 16, and 24 days after inoculation (DAI). All other birds and all mice were euthanized 60 DAI. Schizonts were observed in the lungs using histology and immunostaining in birds examined prior to 60 DAI. Sarcocysts with a ~ 1.5-MUm-thick wall were found in the breast, thigh, and tongue of some birds. Sarcocystis asexual stages were isolated in cell cultures inoculated with sporozoites. Parasite DNA isolated from bird tissues and cell cultures demonstrated that S. falcatula-like parasites were present in all samples derived from positive opossums. Asexual stages molecularly characterized as S. lindsayi like were isolated in cell culture from one opossum with an apparent multiple infection. This study demonstrated that D. aurita is a definitive host for S. falcatula-like parasites and indicates that S. lindsayi-like parasites can be found in coinfections of this opossum species.

AB - BACKGROUND: Despite reductions in youth pedestrian and bicyclist deaths over the past two decades, these injuries remain a substantial cause of morbidity and mortality for children and adolescents. There is a need for additional information on non-fatal pediatric pedestrian injuries and the role of traumatic brain injury (TBI), a leading cause of acquired disability. METHODS: Using a multi-year national sample of emergency department (ED) records, we estimated annual motorized-vehicle related pediatric pedestrian and bicyclist (i.e. pedalcyclist) injury rates by age and region. We modeled in-hospital fatality risk controlling for age, gender, injury severity, TBI, and trauma center status. RESULTS: ED visits for pediatric pedestrian injuries declined 19.3% (95% CI 16.8, 21.8) from 2006 to 2012, with the largest decreases in 5-to-9 year olds and 10-to 14 year olds. Case fatality rates also declined 14.0%. There was no significant change in bicyclist injury rates. TBI was implicated in 6.7% (95% CI 6.3, 7.1) of all pedestrian and bicyclist injuries and 55.5% (95% CI 27.9, 83.1) of fatalities. Pedestrian ED visits were more likely to be fatal than bicyclist injuries (aOR = 2.4, 95% CI 2.3, 2.6), with significant additive interaction between pedestrian status and TBI. CONCLUSIONS: TBI in young pedestrian ED patients was associated with a higher risk of mortality compared to cyclists. There is a role for concurrent clinical focus on TBI recovery alongside ongoing efforts to mitigate and prevent motor vehicle crashes with pedestrians and bicyclists. Differences between youth pedestrian and cycling injury trends merit further exploration and localized analyses, with respect to behavior patterns and interventions. ED data captures a substantially larger number of pediatric pedestrian injuries compared to crash reports and can play a role in those analyses. PMID- 29192338 TI - Evolutionary trends in animal ribosomal DNA loci: introduction to a new online database. AB - Ribosomal DNA (rDNA) loci encoding 5S and 45S (18S-5.8S-28S) rRNAs are important components of eukaryotic chromosomes. Here, we set up the animal rDNA database containing cytogenetic information about these loci in 1343 animal species (264 families) collected from 542 publications. The data are based on in situ hybridisation studies (both radioactive and fluorescent) carried out in major groups of vertebrates (fish, reptiles, amphibians, birds, and mammals) and invertebrates (mostly insects and mollusks). The database is accessible online at www.animalrdnadatabase.com . The median number of 45S and 5S sites was close to two per diploid chromosome set for both rDNAs despite large variation (1-74 for 5S and 1-54 for 45S sites). No significant correlation between the number of 5S and 45S rDNA loci was observed, suggesting that their distribution and amplification across the chromosomes follow independent evolutionary trajectories. Each group, irrespective of taxonomic classification, contained rDNA sites at any chromosome location. However, the distal and pericentromeric positions were the most prevalent (> 75% karyotypes) for 45S loci, while the position of 5S loci was more variable. We also examined potential relationships between molecular attributes of rDNA (homogenisation and expression) and cytogenetic parameters such as rDNA positions, chromosome number, and morphology. PMID- 29192339 TI - Cytomixis in plants: facts and doubts. AB - The migration of nuclei between plant cells (cytomixis) is a mysterious cellular phenomenon frequently observable in the male meiosis of higher plants. Cytomixis attracts attention because of unknown cellular mechanisms underlying migration of nuclei and its potential evolutionary significance, since the genetic material is transferred between the cells that form pollen. Although cytomixis was discovered over a century ago, the advance in our understanding of this process has been rather insignificant because of methodological difficulties. The data that allowed for a new insight into this phenomenon were obtained by examining the migrating nuclei with electron and confocal laser microscopy, immunostaining, and fluorescence in situ hybridization. As has been shown, the chromatin migrating between cells is surrounded by an undamaged nuclear membrane. Such chromatin does not undergo heterochromatization and contains normal euchromatin markers. The condensation degree of the migrating chromatin corresponds to the current meiotic stage, and normal structures of synaptonemal complex are present in the migrating part of the nucleus. The cells involved in cytomixis lack any detectable morphological and molecular markers of programmed cell death. It has been shown that individual chromosomes and genomes (in the case of allopolyploids) have no predisposition to the migration between cells, i.e., parts of the nucleus are involved in cytomixis in a random manner. However, the fate of migrating chromatin after it has entered the recipient cell is still vague. A huge amount of indirect data suggests that migrating chromatin is incorporated into the nucleus of the recipient cell; nonetheless, the corresponding direct evidences are still absent. No specific markers of cytomictic chromatin have been yet discovered. Thus, the causes and consequences of cytomixis are still disputable. This review briefs the recent data on the relevant issues, describes the classical and modern methodological approaches to analysis of the intercellular migration of nuclei, and discusses the problems in cytomixis research and its prospects. PMID- 29192340 TI - The effect of polarized light on the organization of collagen secreted by fibroblasts. AB - Recent studies have demonstrated the beneficial effect of low-power lasers and polarized light on wound healing, inflammation, and the treatment of rheumatologic and neurologic disorders. The overall effect of laser irradiation treatment is still controversial due to the lack of studies on the biochemical mechanisms and the optimal parameters for the incident light that should be chosen for particular applications. Here, we study how NIH/3T3 fibroblasts respond to irradiation with linearly polarized light at different polarization angles. In particular, we examined vascular endothelial growth factor (VEGF) secretion, differentiation to myofibroblasts, and collagen organization in response to 800 nm polarized light at 0 degrees , 45 degrees , 90 degrees , and 135 degrees with a power density of 40 mW/cm2 for 6 min every day for 6 days. Additional experiments were conducted in which the polarization angle of the incident was changed every day to induce an isotropic distribution of collagen. The data presented here shows that polarized light can upregulate VEGF production, myofibroblast differentiation, and induce different collagen organization in response to different polarization angles of the incident beam. These results are encouraging and demonstrate possible methods for controlling cell response through the polarization angle of the laser light, which has potential for the treatment of wounds. PMID- 29192341 TI - Linking Time-Use Data to Explore Health Outcomes: Choosing to Vaccinate Against Influenza. AB - To inform public health and medical decision makers concerning vaccination interventions, a methodology for merging and analyzing detailed activity data and health outcomes is presented. The objective is to investigate relationships between individual's activity choices and their decision to receive an influenza vaccination. Data from the Behavioral Risk Factor Surveillance System (BRFSS) are used to predict vaccination rates in the American Time Use Survey (ATUS) data between 2003 and 2013 by using combined socioeconomic and demographic characteristics. The correlations between the extensive (do or not do) and intensive (how much) decisions to perform activities and influenza vaccination are further explored. Significant positive and negative correlations were found between several activities and vaccination. For some activities, the sign of the correlation flips when considering either the intensive or the extensive decision. This flip occurs with highly studied activities, like smoking. Correlations between activities and vaccination can provide an additional metric for targeting those least likely to vaccinate. The methodology outlined in this paper can be replicated to explore correlation among actions and other health outcomes. PMID- 29192342 TI - Zoonotic Enterobacterial Pathogens Detected in Wild Chimpanzees. AB - Infectious diseases including those acquired through direct or indirect contact with people and livestock threaten the survival of wild great apes. Few studies have reported enterobacterial pathogens in chimpanzees. We used multiplex PCR to screen faeces of chimpanzees sharing a landscape with villagers and livestock in Bulindi, Uganda for Salmonella spp., enterohemorrhagic Escherichia coli (E. coli) and Shigella spp./enteroinvasive E. coli. All three potentially zoonotic pathogens were detected. Individual prevalence ranged between 7 and 20%, with most infections observed in mature male chimpanzees. These preliminary findings suggest detailed investigation of enterobacterial infections in people, primates and livestock in this ecosystem is warranted. PMID- 29192343 TI - A View on the Importance of "Multi-Attribute Method" for Measuring Purity of Biopharmaceuticals and Improving Overall Control Strategy. AB - Today, we are experiencing unprecedented growth and innovation within the pharmaceutical industry. Established protein therapeutic modalities, such as recombinant human proteins, monoclonal antibodies (mAbs), and fusion proteins, are being used to treat previously unmet medical needs. Novel therapies such as bispecific T cell engagers (BiTEs), chimeric antigen T cell receptors (CARTs), siRNA, and gene therapies are paving the path towards increasingly personalized medicine. This advancement of new indications and therapeutic modalities is paralleled by development of new analytical technologies and methods that provide enhanced information content in a more efficient manner. Recently, a liquid chromatography-mass spectrometry (LC-MS) multi-attribute method (MAM) has been developed and designed for improved simultaneous detection, identification, quantitation, and quality control (monitoring) of molecular attributes (Rogers et al. MAbs 7(5):881-90, 2015). Based on peptide mapping principles, this powerful tool represents a true advancement in testing methodology that can be utilized not only during product characterization, formulation development, stability testing, and development of the manufacturing process, but also as a platform quality control method in dispositioning clinical materials for both innovative biotherapeutics and biosimilars. PMID- 29192344 TI - Pulseless supracondylar humeral fractures in children: vascular complications in a ten year series. AB - PURPOSE: The management of pulseless supracondylar fractures remains controversial. The aims of this study were to: (1) analyse functional and vascular outcomes of conservative treatment for cases with absent pulse before reduction, whether patients showed limb ischaemia or not; and (2) identify factors associated with vascular complications. METHODS: Twenty-seven children with absent pulses on presentation were treated consecutively between 1999 and 2009. The brachial artery was surgically explored in cases of persistent signs of ischaemia after reduction. Signs of vascular impairment were recorded in the early post-operative period and at a mean final follow-up of 3.5 years. RESULTS: Recurrent ischaemia with a compartment syndrome occurred in a patient with initial ischaemia and a pink, pulseless hand after reduction. Patients with an initially well-perfused hand and those with pre-operative ischaemia and palpable pulses after reduction had satisfactory outcomes, as did patients with early arterial exploration. No patient showed signs of chronic vascular impairment. The need for vascular repair was significantly correlated with open fracture, initial ischaemia and nerve impairment. CONCLUSIONS: Conservative management of supracondylar fractures with absent pulses avoided long-term vascular complications provided that patients with a pulseless, well-perfused hand on presentation were closely monitored after reduction. Further study is necessary to determine whether a forearm Doppler would help identify children with absent pulses after reduction who need surgical revascularisation due to an insufficient collateral circulation. PMID- 29192345 TI - Transporter-Mediated Interaction Between Platinum Drugs and Sorafenib at the Cellular Level. AB - Combining the multikinase inhibitor sorafenib with the platinum-based chemotherapy of solid tumors was expected to improve treatment outcome. However, in many clinical trials, no benefit from sorafenib addition to the platinum containing regimen could be demonstrated. Moreover, in some studies, decreased survival of ovarian cancer patients as well as non-small cell lung cancer patients with squamous cell histology was observed. The aim of this study was to investigate the cellular mechanisms of the pharmacological interaction between platinum drugs and sorafenib in different cancer cell lines. The interaction was characterized by combination index analysis, platinum accumulation and DNA platination were determined using flameless atomic absorption spectrometry, and protein expression was assessed with Western blot. In the sensitive A2780 ovarian carcinoma and H520 squamous cell lung carcinoma cell lines, sorafenib induced downregulation of Na+,K+-ATPase. In A2780 cells, the kinase inhibitor also decreased the expression of copper transporter 1 (CTR1). As a result, sorafenib treatment led to a diminished cellular accumulation of cisplatin and carboplatin and to a decrease in DNA platination in these cell lines. This was not the case in the cisplatin-resistant A2780cis ovarian carcinoma and H522 lung adenocarcinoma cell lines featuring lower basal expression of the above-mentioned transporters. In all cell lines studied, an antagonistic interaction between platinum drugs and sorafenib was found. Our results suggest that sorafenib impairs cisplatin and carboplatin uptake through downregulation of CTR1 and/or Na+,K+-ATPase resulting in reduction of DNA platination. This effect is not observed in cancer cells with defects in platinum accumulation. PMID- 29192346 TI - In Vitro Sonothrombolysis Enhancement by Transiently Stable Microbubbles Produced by a Flow-Focusing Microfluidic Device. AB - Therapeutic approaches that enhance thrombolysis by combining recombinant tissue plasminogen activator (rtPA), ultrasound, and/or microbubbles (MBs) are known as sonothrombolysis techniques. To date, sonothrombolysis approaches have primarily utilized commercially available MB formulations (or derivatives thereof) with diameters in the range 1-4 um and circulation lifetimes between 5 and 15 min. The present study evaluated the in vitro sonothrombolysis efficacy of large diameter MBs (d MB >= 10 um) with much shorter lifetimes that were produced on demand and in close proximity to the blood clot using a flow-focusing microfluidic device. MBs with a N2 gas core and a non-crosslinked bovine serum albumin shell were produced with diameters between 10 and 20 um at rates between 50 and 950 * 103 per second. Use of these large MBs resulted in approximately 4.0-8.8 fold increases in thrombolysis rates compared to a clinical rtPA dose and approximately 2.1-4.2 fold increases in thrombolysis rates compared to sonothrombolysis techniques using conventional MBs. The results of this study indicate that the large diameter microbubbles with transient stability are capable of significantly enhanced in vitro sonothrombolysis rates when delivered directly to the clot immediately following production by a flow focusing microfluidic device placed essentially in situ adjacent to the clot. PMID- 29192347 TI - Pharmacogenetics of thiopurines for inflammatory bowel disease in East Asia: prospects for clinical application of NUDT15 genotyping. AB - The thiopurine drugs 6-mercaptopurine (6-MP) and azathiopurine (AZA) are widely used to treat inflammatory bowel disease. However, the incidence of adverse reactions is high, particularly in Asia, and the mechanisms of toxicity in Asian populations remain unclear. Thiopurine S-methyltransferase (TPMT) is a well-known enzyme that inactivates AZA or 6-MP through methylation and is one of the few pharmacogenetic predictors used in clinical settings in Western countries. Individuals carrying TPMT-deficient genetic variants require reduced drug doses, but this treatment modification is are not applicable to East Asian populations. Several genes code thiopurine-metabolizing enzymes, including TPMT, multidrug resistance protein 4, and inosine triphosphatase. These genes have been studied as candidate pharmacogenetic markers; however, it remains unclear why Asian populations seem to be more intolerant than other ethnic groups to a full dose of thiopurines. A genome-wide association approach to identify Asian-specific pharmacogenetic markers in Korean patients with Crohn's disease revealed that a non-synonymous single nucelotide polymorphism in nucleoside diphosphate-linked moiety X-type motif 15 (NUDT15) which causes p.Arg139Cys was strongly associated with thiopurine-induced early leukopenia. Six common haplotypes of NUDT15 were reported, and five variants showed medium-to-low enzyme activities, compared with the wild haplotype. NUDT15 hydrolyzes the thiopurine active metabolites 6-thio GTP and 6-thio-dGTP; variants of NUDT15 had lower enzyme activities, causing higher levels of thiopurine active metabolites, resulting in thiopurine-induced leukopenia. In clinical application, NUDT15 genotyping is a good candidate for predicting thiopurine toxicity in East Asian populations. However, the association of NUDT15 diplotypes with thiopurine toxicity remains unclear. Further analyses with large cohorts to confirm the clinical effects of each haplotype are planned. PMID- 29192348 TI - A nationwide population-based study of common bile duct stone recurrence after endoscopic stone removal in Korea. AB - BACKGROUND: There is no consensus whether patients who underwent endoscopic common bile duct (CBD) stone removal should be followed up periodically and whether patients with gallbladder (GB) stones should undergo cholecystectomy. Thus, this study aimed to investigate the recurrence rate of CBD stones and the difference in recurrence rate according to cholecystectomy. METHODS: We conducted a population-based study using the National Health Insurance database. Patients diagnosed with CBD stones and with procedure registry of endoscopic stone removal were included. The primary outcome was the recurrence rate of CBD stones. The secondary outcome was the difference in recurrence rate of CBD stones according to cholecystectomy. RESULTS: A total of 46,181 patients were identified. The mean follow-up was 4.2 years. The first CBD stone recurrence occurred in 5228 (11.3%) patients. The cumulative first recurrence rate was low. However, the second and third recurrence rates were 23.4 and 33.4%, respectively. The cumulative second and third recurrence rates were high and gradually increased with time. The recurrence rate in the non-cholecystectomy group was higher than that in the cholecystectomy group (p < 0.0001). The relative risk for CBD stone recurrence in the non-cholecystectomy group was higher in younger patients, with 3.198 in patients < 50 years, 2.371 in 50-59 years, 1.618 in 60-69 years, and 1.262 in >= 70 years (p < 0.0001). CONCLUSIONS: Regular follow-up is not routinely recommended for patients with first-time endoscopic stone removal, but is recommended for patients with recurrent stones. Cholecystectomy is recommended for patients with GB stones who are younger than 70 years. PMID- 29192349 TI - Placement of an antibiotic oral pack on the hard palate after primary cleft palatoplasty: a randomized controlled trial into the effect on fistula rates. AB - OBJECTIVE: The objective of this study is to determine whether placement of an antibiotic oral pack on the hard palate reduces fistula rates after primary cleft palatoplasty. SUBJECTS AND METHODS: This study was a parallel blocked randomized controlled trial. The study consisted of two groups of 100 patients each with non syndromic unilateral complete cleft lip, alveolus, and hard and soft palate that underwent primary palatoplasty. Group A had an oral pack placed on the hard palate for 5 days postoperatively while group B did not. Occurrence of fistulae between both groups was tested using odds ratios (OR). RESULTS: In 2% of the patients in group A, a fistula was found 6 months after palatal surgery. In contrast, in 21% of the patients in group B, a palatal fistula could be confirmed. The fistula occurrence in group A was statistically significantly lower than that in group B (OR = 0.0768, CI = [0.02 ... 0.34], p < 0.001). CONCLUSION: The findings of this study provide evidence that the rate of fistula formation after primary palatoplasty is significantly reduced if a pack soaked with antibiotic cream is placed on the palate postoperatively for 5 days. CLINICAL RELEVANCE: The use of an antibiotic pack after cleft palate repair can be recommended to prevent occurrence of oronasal fistulae. PMID- 29192351 TI - The implication of probiotics in the prevention of dental caries. AB - The current oral health crisis, whose causes are varied and complex, necessitates timely oral evaluation and early detection and treatment of oral health problems. Dramatic changes in eating habits and lifestyles are associated with the recent decline in oral health. Probiotics are "good" bacteria that support digestion and a healthy immune system and offer various health benefits to the host. Traditionally, probiotics have been used to improve gut health; the most common uses have historically been as a treatment or prevention of gastrointestinal infections and disease. During the last decade, studies have additionally suggested the intake of probiotics for oral health purposes. Probiotic use provides an effective strategy to combat oral disease, including the development of dental caries and periodontal infection. The aim of this review is to describe the beneficial roles of probiotic bacteria in the oral cavity and the potential mechanisms by which these bacteria exert their effects on oral health. PMID- 29192350 TI - Serum cholesterol trajectories in the 10 years prior to lymphoma diagnosis. AB - PURPOSE: Many studies suggest a role for cholesterol in cancer development. Serum cholesterol levels have been observed to be low in newly diagnosed lymphoma cases. The objective of these analyses was to examine the time-varying relationship of cholesterol with lymphomagenesis in the 10 years prior to diagnosis by lymphoma subtype. METHODS: Participants were selected from the combined membership of six National Cancer Institute-funded Cancer Research Network health plans from 1998 to 2008, excluding members with human immunodeficiency virus, cancer (except lymphoma), or organ transplants. Incident lymphoma cases within this population were ascertained and matched with up to five controls. Total serum cholesterol, high-density lipoprotein, and low-density lipoprotein were collected from plan databases. Multilevel, multivariable longitudinal models were fit after choosing the best polynomial order by deviance statistics for selected lymphoma histotypes to examine pre-diagnosis cholesterol trajectories: Hodgkin lymphoma (n = 519) and all non-Hodgkin lymphomas combined (n = 12,635) as well as six subtypes of the latter. RESULTS: For all categories, lymphoma cases had statistically significantly lower estimated total serum cholesterol, high-density lipoprotein, and low-density lipoprotein levels than controls in the years prior to diagnosis/index date. Between-group differences were most pronounced 3-4 years prior to diagnosis, when cases' cholesterol levels declined steeply. CONCLUSIONS: This analysis is the first to examine changes in serum cholesterol for a decade prior to lymphoma diagnosis. A drop in cholesterol levels was evident several years before diagnosis. Our results suggest that cholesterol-related pathways have an important relationship with lymphomagenesis and low cholesterol could be a preclinical lymphoma marker.

PMID- 29192353 TI - Effects of a mobility monitoring system on the cost of care in relation to reimbursement at Swiss nursing homes: learnings from a randomized controlled trial. AB - BACKGROUND/OBJECTIVE: Nursing homes in Switzerland are under pressure to efficiently coordinate staff activities to cover their personnel costs under the care financing system. In this study, the use of a mobility monitoring system accompanied with case conferences was investigated in order to improve sleep quality and estimate the cost benefit of this intervention. METHOD: In an open two-phase randomized controlled trial at three nursing homes, residents with cognitive impairment were randomly assigned to an intervention group and a control group. In the intervention group, a 10-week period of intensive use of the monitoring system and case conferences led by an advanced nurse practitioner (Phase I) was followed by 3 months of reduced use of the monitoring system and case conferences led by an internal registered nurse (Phase II). In the control group, the monitoring system was only used for data acquisition. Nurses reported the activities with a specifically developed tool. Based on the recorded activities, the cost of care was calculated. The correlating reimbursement per patient was calculated from the care levels in the Swiss reimbursement system. Data from 44 residents was included in the analysis with a linear mixed model. RESULTS: Although analysis revealed no statistically significant effects, results indicate that the use of a monitoring system can guide nurses in organizing their tasks to increase effectiveness. Information systems such as the mobility monitor can help to identify single outliers that do not correspond with the overall situation. CONCLUSION: In the health care system, problematic individual cases can account for a disproportionally high cost levels. It was shown that information systems can have a significant economic impact in the long run. TRIAL REGISTRATION: The study is registered at the German Clinical Trials Register under the Nr. DRKS-ID: DRKS00006829 . PMID- 29192354 TI - Prognostic Implication of Inflammation-based Prognostic Scores in Patients with Intrahepatic Cholangiocarcinoma Treated with First-line Gemcitabine plus Cisplatin. AB - Background We aimed to comprehensively evaluate the prognostic value of inflammation-based prognostic scores, including the modified Glasgow Prognostic Score (mGPS), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR), exclusively in patients with advanced intrahepatic cholangiocarcinoma (iCCA). Methods Between May 2010 and April 2015, 305 patients with histologically documented unresectable or metastatic iCCA were treated with first-line gemcitabine plus cisplatin (GemCis). Among these, 257 patients had complete data for inflammation-based prognostic scores and were included. Results Median age was 59 (range: 27-78) years, and 158 patients (61.5%) were males. High mGPS was independently associated with poor progression-free survival (PFS; mGPS >=1 vs. 0: median, 3.9 vs. 5.5 months; P = 0.001) and overall survival (OS; mGPS >=1 vs. 0; median, 6.9 vs. 14.1 months; P = 0.002) in the multivariate analysis. Regarding high NLR (> median) and PLR (> median), although a potential association existed with poor PFS or OS in the univariate analysis, these did not remain as significant in the multivariate analyses. Conclusion The current study suggests that mGPS might be the relevant prognostic index that could stratify the survival outcomes of patients with unresectable or metastatic iCCA who received first-line GemCis. PMID- 29192356 TI - Measuring 3D shape in orthodontics through geometric morphometrics. AB - BACKGROUND: Geometric morphometrics (GMM) has been traditionally applied to the field of biology to study developmental differentiations between species. Orthodontics deals with the shape and size of the face and its components. While several tools have been used to measure size, proportions, and relations between anatomical components, shape has been mainly described by esthetic criteria. The purpose of this paper is to present methods to measure shape of 3D orthodontic data, beyond the conventional tools that have been traditionally used in cephalometrics and in facial and dental cast analysis. FINDINGS: The authors showcase an example of applying geometric morphometrics to measure palates from scanned dental casts. GMM can be used as a useful tool to describe the three dimensional shape of surfaces of orthodontic interest. A general introduction to the theoretical principles of how to apply GMM is provided. CONCLUSIONS: Variability can be measured through the Principal Component Analysis (PCA) and can lead to the identification of shape patterns and sources of variability of the shape, independently from changes in size. PMID- 29192355 TI - Venous occlusion plethysmography vs. Doppler ultrasound in the assessment of leg blood flow kinetics during different intensities of calf exercise. AB - PURPOSE: It has recently been shown that venous occlusion plethysmography (VOP) can successfully assess the rate of increase in leg blood flow (LBF) (LBF kinetics) responses during calf exercise, but there is lack of data supporting its validity. METHODS: Using Doppler ultrasound (DU) as a criterion standard technique, we tested the hypothesis that VOP would provide similar estimates of LBF kinetics responses as DU during calf plantar-flexion exercise at a range of different intensities. Ten healthy men performed repeated intermittent calf plantar-flexion contractions (3 s duty cycles, 1 s contraction/2 s relaxation) at 30, 50 and 70% maximum voluntary contraction (MVC) on different days. RESULTS: Resting LBF values were significantly (P < 0.05) larger for DU than VOP but the overall mean LBF responses during exercise were not different (P > 0.05) between DU and VOP (30% MVC: 330 +/- 78 vs. 313 +/- 92 ml/min; 50% MVC: 515 +/- 145 vs. 483 +/- 164 ml/min; 70% MVC: 733 +/- 218 vs. 616 +/- 229 ml/min). LBF kinetics analyses revealed that the end-amplitude at the highest intensity (70% MVC) was significantly higher when measured by DU compared with VOP, but all other kinetics parameters were not different between VOP and DU. CONCLUSIONS: Given that these slight differences in amplitude observed during exercise can be explained by differences in vascular regions which the two techniques assess, our results suggest that VOP can accurately assess LBF kinetics responses during calf plantar-flexion exercise at intensities between 30 and 70% MVC. PMID- 29192357 TI - Three new species of Paraboea (Gesneriaceae) from limestone karsts of China based on morphological and molecular evidence. AB - BACKGROUND: The limestone karsts of Southeast Asia and South China are a major biodiversity hotspot of global terrestrial biomes. With more than 130 described species, Paraboea has become one of the most characteristic plant groups in the Southeast Asian limestone flora. During the course of extensive field work on the limestone formations of southern and southwestern China, three unknown species of Paraboea were collected. RESULTS: Molecular phylogenetic analyses based on nuclear ITS and chloroplast trnL-F sequences strongly confirm the placements of the three new species in Paraboea sensu Puglisi et al. (Taxon 65:277-292. https://doi.org/10.12705/652.5 , 2016). Moreover, these three novelties can be distinguished from known Paraboea species with distinct morphological characters, further supporting their recognition as new species. CONCLUSIONS: With the support of detailed morphological studies and molecular phylogenetic analyses, Paraboea dushanensis, P. sinovietnamica and P. xiangguiensis are recognized as three species new to science. PMID- 29192358 TI - Cryopreservation of male and female gonial cells by vitrification in the critically endangered cyprinid honmoroko Gnathopogon caerulescens. AB - We investigated the feasibility of cryopreservation of spermatogonia and oogonia in the critically endangered cyprinid honmoroko Gnathopogon caerulescens using slow-cooling (freezing) and rapid-cooling (vitrification) methods. Initially, we examined the testicular cell toxicities and glass-forming properties of the five cryoprotectants: ethylene glycol (EG), glycerol (GC), dimethyl sulfoxide (DMSO), propylene glycol (PG), and 1,3-butylene glycol (BG), and we determined cryoprotectant concentrations that are suitable for freezing and vitrification solutions, respectively. Subsequently, we prepared the freezing solutions of EG, GC, DMSO, PG, and BG at 3, 2, 3, 2, and 2 M and vitrification solutions at 7, 6, 5, 5, and 4 M, respectively. Following the cryopreservation of the testicular cells mainly containing early-stage spermatogenic cells (e.g., spermatogonia and primary spermatocytes), cells were cultured for 7 days and immunochemically stained against germ cell marker protein Vasa. Areas occupied by Vasa-positive cells indicated that vitrification led to better survival of germ cells than the freezing method, and the best result was obtained with 5 M PG, about 50% recovery of germ cells following vitrification. In the case of ovarian cells containing oogonia and stage I, II, and IIIa oocytes, vitrification with 5 M DMSO resulted the best survival of oogonia, with equivalent cell numbers to those cultured without vitrification. The present data suggest that male and female gonial cells of the endangered species G. caerulescens can be efficiently cryopreserved using suitable cryoprotectants for spermatogonia and oogonia, respectively. PMID- 29192359 TI - A field and laboratory study of the responses of cytoprotection and osmoregulation to salinity stress in mosquitofish (Gambusia affinis). AB - The mosquitofish (Gambusia affinis) naturally inhabits freshwater (FW; 1-30/00) and seawater (SW; 28-330/00) ponds in constructed wetland. To explore the physiological status and molecular mechanisms for salinity adaptation of the mosquitofish, cytoprotective responses and osmoregulation were examined. In the field study, activation of protein quality control (PQC) mechanism through upregulation of the abundance of heat shock protein (HSP) 90 and 70 and ubiquitin conjugated proteins was found in the mosquitofish gills from SW pond compared to the individuals of FW pond. The levels of aggregated proteins in mosquitofish gills had no significant difference between FW and SW ponds. Furthermore, the osmoregulatory responses revealed that the body fluid osmolality and muscle water contents of the mosquitofish from two ponds were maintained within a physiological range while branchial Na+/K+-ATPase (NKA) expression was higher in the individuals from SW than FW ponds. Subsequently, to further clarify whether the cellular stress responses and osmoregulation were mainly induced by hypertonicity, a laboratory salinity acclimation experiment was conducted. The results from the laboratory experiment were similar to the field study. Branchial PQC as well as NKA responses were induced by SW acclimation compared to FW acclimated individuals. Taken together, induction of gill PQC and NKA responses implied that SW represents an osmotic stress for mosquitofish. Activation of PQC was suggested to provide an osmoprotection to prevent the accumulation of aggregated proteins. Moreover, an increase in branchial NKA responses for osmoregulatory adjustment was required for the physiological homeostasis of body fluid osmolality and muscle water content.

PMID- 29192360 TI - Hyperglycemia-induced cardiac contractile dysfunction in the diabetic heart. AB - The development of a diabetic cardiomyopathy is a multifactorial process, and evidence is accumulating that defects in intracellular free calcium concentration [Ca2+]i or its homeostasis are related to impaired mechanical performance of the diabetic heart leading to a reduction in contractile dysfunction. Defects in ryanodine receptor, reduced activity of the sarcoplasmic reticulum calcium pump (SERCA) and, along with reduced activity of the sodium-calcium exchanger (NCX) and alterations in myofilament, collectively cause a calcium imbalance within the diabetic cardiomyocytes. This in turn is characterized by cytosolic calcium overloading or elevated diastolic calcium leading to heart failure. Numerous studies have been performed to identify the cellular, subcellular, and molecular derangements in diabetes-induced cardiomyopathy (DCM), but the precise mechanism(s) is still unknown. This review focuses on the mechanism behind DCM, the onset of contractile dysfunction, and the associated changes with special emphasis on hyperglycemia, mitochondrial dysfunction in the diabetic heart. Further, management strategies, including treatment and emerging therapeutic modalities, are discussed. PMID- 29192363 TI - Quantitative and Visual Assessments toward Potential Sub-mSv or Ultrafast FDG PET Using High-Sensitivity TOF PET in PET/MRI. AB - PURPOSE: Newer high-performance time-of-flight (TOF) positron emission tomography (PET) systems have the capability to preserve diagnostic image quality with low count density, while maintaining a high raw photon detection sensitivity that would allow for a reduction in injected dose or rapid data acquisition. To assess this, we performed quantitative and visual assessments of the PET images acquired using a highly sensitive (23.3 cps/kBq) large field of view (25-cm axial) silicon photomultiplier (SiPM)-based TOF PET (400-ps timing resolution) integrated with 3 T-MRI in comparison to PET images acquired on non-TOF PET/x-ray computed tomography (CT) systems. PROCEDURES: Whole-body 2-deoxy-2-[18F]fluoro-D-glucose ([18F]FDG) PET/CT was acquired for 15 patients followed by whole body PET/magnetic resonance imaging (MRI) with an average injected dose of 325 +/- 84 MBq. The PET list mode data from PET/MRI were reconstructed using full datasets (4 min/bed) and reduced datasets (2, 1, 0.5, and 0.25 min/bed). Qualitative assessment between PET/CT and PET/MR images were made. A Likert-type scale between 1 and 5, 1 for non-diagnostic, 3 equivalent to PET/CT, and 5 superior quality, was used. Maximum and mean standardized uptake values (SUVmax and SUVmean) of normal tissues and lesions detected were measured and compared. RESULTS: Mean visual assessment scores were 3.54 +/- 0.32, 3.62 +/- 0.38, and 3.69 +/- 0.35 for the brain and 3.05 +/- 0.49, 3.71 +/- 0.45, and 4.14 +/- 0.44 for the whole-body maximum intensity projections (MIPs) for 1, 2, and 4 min/bed PET/MR images, respectively. The SUVmean values for normal tissues were lower and statistically significant for images acquired at 4, 2, 1, 0.5, and 0.25 min/bed on the PET/MR, with values of - 18 +/- 28 % (p < 0.001), - 16 +/- 29 % (p = 0.001), - 16 +/- 31 % (p = 0.002), - 14 +/- 35 % (p < 0.001), and - 13 +/- 34 % (p = 0.002), respectively. SUVmax and SUVpeak values of all lesions were higher and statistically significant (p < 0.05) for 4, 2, 1, 0.50, and 0.25 min/bed PET/MR datasets. CONCLUSION: High-sensitivity TOF PET showed comparable but still better visual image quality even at a much reduced activity in comparison to lower-sensitivity non-TOF PET. Our data translates to a seven times reduction in either injection dose for the same time or total scan time for the same injected dose. This "ultra-sensitivity" PET system provides a path to clinically acceptable extremely low-dose FDG PET studies (e.g., sub 1 mCi injection or sub mSv effective dose) or PET studies as short as 1 min/bed (e.g., 6 min of total scan time) to cover whole body without compromising diagnostic performance. PMID- 29192364 TI - Liver metastases from prostate cancer at 11C-Choline PET/CT: a multicenter, retrospective analysis. AB - AIM: During our daily clinical practice using 11C-Choline PET/CT for restaging patients affected by relapsing prostate cancer (rPCa) we noticed an unusual but significant occurrence of hypodense hepatic lesions with a different tracer uptake. Thus, we decided to evaluate the possible correlation between rPCa and these lesions as possible hepatic metastases. MATERIALS AND METHODS: We retrospectively enrolled 542 patients diagnosed with rPCa in biochemical relapse after a radical treatment (surgery and/or radiotherapy). Among these, patients with a second tumor or other benign hepatic diseases were excluded. All patients underwent 11C-Choline PET/CT during the standard restaging workup of their disease. We analyzed CT images to evaluate the presence of hypodense lesions and PET images to identify the relative tracer uptake. In accordance to the subsequent oncological history, five clinical scenarios were recognized [Table 1]: normal low dose CT (ldCT) and normal tracer distribution (Group A); evidence of previously unknown hepatic round hypodense areas at ldCT with normal rim uptake (Group B); evidence of previously known hepatic round hypodense areas at ldCT stable over time and with normal rim uptake (Group C); evidence of previously known hepatic round hypodense areas at ldCT, in a previous PET/CT scan, with or without rim uptake and significantly changing over time in terms of size and/or uptake (Group D); evidence of hepatic round hypodense areas at ldCT with or without rim uptake confirmed as prostate liver metastases by histopathology, triple phase ceCT, ce-ultra sound (CEUS) and clinical/biochemical evaluation (Group E). We evaluated the correlation with PSA level at time of scan, rim SUVmax and association with local relapse or non-hepatic metastases (lymph nodes, bone, other parenchyma). RESULTS: Five hundred and forty-two consecutive patients were retrospectively enrolled. In 140 of the 542 patients more than one 11C-choline PET/CT had been performed. A total of 742 11C-Choline PET/CT scans were analyzed. Of the 542 patients enrolled, 456 (84.1%) had a normal appearance of the liver both at ldCT and PET (Group A). 19/542 (3,5%) belonged to Group B, 13/542 (2.4%) to Group C, 37/542 (6.8%) to Group D and 18/542 (3.3%) to Group E. Mean SUVmax of the rim was: 4.5 for Group B; 4.2 for Group C; 4.8 for Group D; 5.9 for Group E. Mean PSA level was 5.27 for Group A, 7.9 for Group B, 10.04 for Group C, 10.01 for Group D, 9.36 for Group E. Presence of positive findings at 11C-Choline PET/CT in any further anatomical area (local relapse, lymph node, bone, other extra hepatic sites) correlated with an higher PSA (p = 0.0285). In both the univariate and multivariate binary logistic regression analyses. PSA, SUVmax of the rim, local relapse, positive nodes were not associated to liver mets (Groups D-E) (p > 0.05). On the contrary, a significant correlation was found between the presence of liver metG (group D-E) and bone lesions (p= 0.00193). CONCLUSION: Our results indicate that liver metastases in relapsing prostate cancer may occur frequently. The real incidence evaluation needs more investigations. In this case and despite technical limitations, Choline PET/CT shows alterations of tracer distribution within the liver that could eventually be mistaken for simple cysts but can be suspected when associated to high trigger PSA, concomitant bone lesions or modification over time. In this clinical setting an accurate analysis of liver tracer distribution (increased or decreased uptake) by the nuclear medicine physician is, therefore, mandatory. PMID- 29192365 TI - EANM/EARL FDG-PET/CT accreditation - summary results from the first 200 accredited imaging systems. AB - PURPOSE: From 2010 until July 2016, the EANM Research Ltd. (EARL) FDG-PET/CT accreditation program has collected over 2500 phantom datasets from approximately 200 systems and 150 imaging sites worldwide. The objective of this study is to report the findings and impact of the accreditation program on the participating PET/CT systems. METHODS: To obtain and maintain EARL accredited status, sites were required to complete and submit two phantom scans - calibration quality control (CalQC), using a uniform cylindrical phantom and image quality control (IQQC), using a NEMA NU2-2007 body phantom. Average volumetric SUV bias and SUV recovery coefficients (RC) were calculated and the data evaluated on the basis of quality control (QC) type, approval status, PET/CT system manufacturer and submission order. RESULTS: SUV bias in 5% (n = 96) of all CalQC submissions (n = 1816) exceeded 10%. After corrective actions following EARL feedback, sites achieved 100% compliance within EARL specifications. 30% (n = 1381) of SUVmean and 23% (n = 1095) of SUVmax sphere recoveries from IQQC submissions failed to meet EARL accreditation criteria while after accreditation, failure rate decreased to 12% (n = 360) and 9% (n = 254), respectively. Most systems demonstrated longitudinal SUV bias reproducibility within +/-5%, while RC values remained stable and generally within +/-10% for the four largest and +/-20% for the two smallest spheres. CONCLUSIONS: Regardless of manufacturer or model, all investigated systems are able to comply with the EARL specifications. Within the EARL accreditation program, gross PET/CT calibration errors are successfully identified and longitudinal variability in PET/CT performances reduced. The program demonstrates that a harmonising accreditation procedure is feasible and achievable. PMID- 29192367 TI - Intermedin1-53 Protects Cardiac Fibroblasts by Inhibiting NLRP3 Inflammasome Activation During Sepsis. AB - Sepsis is a disease that occurs as a result of systemic inflammatory response syndrome (SIRS) in response to an infection, contributing to multiple organ dysfunction and a high mortality rate. Interleukin-lbeta (IL-1beta) is a cytokine that plays critical roles in inflammation and cardiac dysfunction during severe sepsis. Intermedin1-53 (IMD1-53) has been recently discovered to possess potential endogenous anti-inflammatory and strong cardiovascular protective effects. To investigate whether IMD1-53 can inhibit the NLRP3/caspase-1/IL-1beta pathway to alleviate cardiac injury and rescue heart function, sepsis was induced in vivo by caecal ligation and puncture (CLP) surgery, and lipopolysaccharides were used as septic stressors for cardiac fibroblasts (CFs) in vitro. The expressions of IMD1-53 receptors in sepsis rat heart were increased. After IMD1 53 treatment, inflammation caused by sepsis in vivo was greatly reduced, as shown by the downregulation of apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), nucleotide-binding domain and leucine-rich repeat containing family, pyrin containing 3 (NLRP3), pro-IL-1beta, caspase 1, and nuclear translocation of nuclear factor-kappaB (NF-kB) protein levels. In addition, cardiac function was significantly improved and mean arterial blood pressure (MABP) increased by 34.8% (P < 0.05) which almost back to normal. Surprisingly, IMD1-53 inhibited cell apoptosis, as caspase 3 activity and Bax expression was significantly reduced in the heart upon IMD1-53 treatment. IMD1-53 abolished the upregulation of ASC, NLRP3, and caspase 1 protein levels in CFs induced by lipopolysaccharide (LPS). IMD1-53 increased cell survival rates and inhibited IL-1beta production in the cell culture medium. IMD1-53 can protect against inflammation and heart injury during sepsis via attenuating the NLRP3/caspase-1/IL-1beta pathway. PMID- 29192368 TI - Are Anal Sex Roles Associated with Preferences for Pre-Exposure Prophylaxis Administration Modalities Among Men Who Have Sex with Men? AB - The current study sought to examine awareness of, willingness to use, and preferences for available and theoretical administration modalities for HIV pre exposure prophylaxis (PrEP) and the association of anal sex roles with these concepts among a sample of men who have sex with men (MSM) in Paris, France. Broadcast advertisements were placed on a popular geosocial-networking smartphone application for MSM to direct users to complete a Web-based survey. MSM answered questions on their recent engagement in condomless anal intercourse and awareness of and willingness to use PrEP in the form of once daily and event-driven pill regimens, long-acting injections, and penile and rectal microbicides as well as sexual roles. Multinomial regression models were fit to assess the association between behaviorally classified anal sexual role and preferences for one of these biomedical prevention modalities. A total of 482 HIV-uninfected MSM completed the survey, 48.1% of whom engaged in some form of condomless anal intercourse in the preceding 3 months. Most respondents (85.3%) had heard of once daily PrEP, but fewer respondents had heard of other prevention strategies. Assuming equal effectiveness, long-acting injections were the most commonly preferred (21.8%). Behaviorally defined "bottom" and "versatile" MSM more frequently preferred long acting injections (32.9% of "bottoms" and 25.3% of "versatiles"). The development of long-acting injections to deliver antiretroviral drugs and topical microbicides may offer more convenient and acceptable options for HIV prevention among MSM, as MSM in this sample were willing to use them and would prefer to use them over currently available pill regimens. PMID- 29192369 TI - Insurers' Influences on Attending Physicians of Workers Sick-listed for Common Mental Disorders: What Are the Impacts on Physicians' Practices? AB - Purpose In many jurisdictions, general practitioners (GPs) play an important role in the sick-leave and return-to-work (RTW) process of individuals with common mental disorders (CMD). Since it is insurers that decide on workers' eligibility for disability benefits, they can influence physicians' ability to act. The nature of these influences remains little documented to date. The aim of this study was therefore to describe these influences and their impacts from the GPs' perspective. Methods Semi-structured interviews were conducted with GPs having a diversified clientele (n = 13). The interviews were audio-recorded, transcribed verbatim and analyzed according to thematic analysis principles. Results The results indicated that the GPs recognized insurers as influencing their practices with patients on sick leave for CMDs. The documented influences were generally seen as constraints, but sometimes as enablers. The impacts of these influences on the GPs' practices depended on the organizational characteristics of their work context (such as limited consultation time) and other characteristics of their practice setting (such as lack of timely access to consultations with specialists). Conclusion The results brought three major issues to light: the quality of the information sent to insurers by GPs, the respect shown (or not) for workers' care preferences, and the relevance of the specialized services offered to support workers' RTW. These issues in turn reveal potential risks for workers, risks that need to be identified and recognized by all parties concerned if we are to come up with possible solutions. PMID- 29192370 TI - Directional Hydrodynamic Sensing by Free-Swimming Organisms. AB - Many aquatic organisms detect the presence of moving objects in their environment, such as predators, by sensing the hydrodynamic disturbances the movements produce. The resultant water flow is readily detectable by stationary organisms, but free-swimming organisms are carried with the surrounding water and may not detect the bulk surrounding flow, which limits the available information about the source. We have developed a theory that clarifies what information is contained in disturbances generated by an attacking predator that is available to a free-swimming organism and might be extracted from local flow deformations alone. The theory shows that, depending on how well the deformations can be measured in space and time, an organism can reduce the range of possible locations, speeds, sizes, and arrival times of the predator. We apply the theory to planktonic copepods that have mechanosensory hairs along a pair of antennules. The study reveals the presence of "blind spots," potential ambiguities in resolving from which of two sides a predator attacks, and whether it generates a bow wave or suction. Our findings lead to specific testable hypotheses concerning optimal escape strategies, which are helpful for interpreting the behavior of evasive prey and designing free-swimming robots with sensory capabilities. PMID- 29192366 TI - Blood platelets and sepsis pathophysiology: A new therapeutic prospect in critical ill patients? AB - Beyond haemostasis, platelets have emerged as versatile effectors of the immune response. The contribution of platelets in inflammation, tissue integrity and defence against infections has considerably widened the spectrum of their role in health and disease. Here, we propose a narrative review that first describes these new platelet attributes. We then examine their relevance to microcirculatory alterations in multi-organ dysfunction, a major sepsis complication. Rapid progresses that are made on the knowledge of novel platelet functions should improve the understanding of thrombocytopenia, a common condition and a predictor of adverse outcome in sepsis, and may provide potential avenues for management and therapy. PMID- 29192371 TI - Management of horizontal duodenal perforation: a report of three cases and review of literature. AB - BACKGROUND: Perforation of the horizontal duodenum is very rare due to the presence in retroperitoneal space. It depicts an unusual clinical picture and is difficult to diagnose, leading to increased morbidity and mortality. The treatment strategies are usually varied and based on small series of cases, literature reviews, and expert opinions. CASE PRESENTATION: Here, we presented three cases of horizontal duodenal perforation in three different clinical processes. The first case, a 30-year-old male patient, presented with abdominal pain and hematemesis after experiencing a physical assault on the previous day. Computed tomography (CT) scan showed rupture of the horizontal duodenum. It was repaired by side-to-side duodenojejunostomy. Postoperatively, he had anastomotic leakage, disseminated intravascular coagulation, and pulmonary failure and recovered after a long hospital stay. The second case, an 81-year-old female, had duodenal perforation with endoscopic coagulation of the bleeding diverticulum. Segmental resection of the duodenum and side-to-side duodenojejunostomy were performed. Postoperatively, there was slight anastomotic leakage, but surgical intervention was not needed. The third case, an 89-year-old female, was a patient with obstructive jaundice due to pancreas head carcinoma, who developed perforation of the horizontal duodenum during endoscopic retrograde cholangiopancreatography (ERCP). After unsuccessful conservative management, duodenojejunostomy at the perforated site and gastric bypass were performed. The postoperative course was uneventful. CONCLUSION: Early suspicion and investigation is necessary for cases of abdominal injuries. CT scan is the investigation of choice. The management options should be based on the clinical condition of the patient, comorbidities, surgical expertise, existing guidelines, and available resources. PMID- 29192372 TI - Prediction of Resectability in Pseudomyxoma Peritonei with a New CT Score. AB - BACKGROUND: Curative treatment of pseudomyxoma peritonei (PMP) is complete cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC). OBJECTIVE: The aim of this study was to build and evaluate a preoperative imaging score to predict resectability. PATIENTS AND METHODS: Between 2007 and 2014, all PMP patients in two tertiary reference centers who underwent laparotomy with intent to undergo CRS and HIPEC were included in this study retrospectively. Thickness of tumor burden was measured on preoperative multidetector-row computed tomography (MDCT) by two radiologists blinded to surgical results in five predetermined areas. Patients were divided into two cohorts with the same resectability rate (building and validation). The performances of the scores were assessed using receiver operating characteristic (ROC) curve analyses. RESULTS: Overall, 126 patients were included, with compete CRS being achieved in 91/126 patients (72.2%). Two cohorts of 63 patients matched by age, sex, burden of disease, resectability rate, and pathological grade were constituted. The MDCT score was the sum of the five measures, and was higher in unresectable disease [median 46.2 mm (range 27.9-74.6) vs. 0.0 mm (range 0.0 14.0), p < 0.001]. Area under the ROC curve was 0.863 (range 0.727-0.968) and 0.801 (range 0.676-0.914) in the building and validation cohorts, respectively. A threshold of 28 mm yielded a sensitivity, specificity, positive predictive and negative predictive value of 94, 81, 81 and 94% in the building cohort, and 80, 68, 59 and 85% in the validation cohort, respectively. Using our score, overall and disease-free survival were increased in the group classified as resectable. CONCLUSION: A simple preoperative MDCT score measuring tumor burden in the perihepatic region is able to predict resectability and survival of PMP patients. PMID- 29192373 TI - Flexible endoscopically assisted evacuation of acute and subacute subdural hematoma through a small craniotomy: preliminary results. AB - BACKGROUND: The first choice to treat acute subdural hematoma (SDH) is a large craniotomy under general anesthesia. However, increasing age or comorbid burden of the patients may render invasive treatment strategy inappropriate. These medically frail patients with SDH may benefit from a combination of small craniotomy and endoscopic hematoma removal, which is less invasive and even available under local anesthesia. Although hematoma evacuation with a rigid endoscope for acute or subacute SDHs has been reported in the literature, use of a flexible endoscope may have distinct advantages. In this article, we attempted to clarify the utility of small craniotomy evacuation with a flexible endoscope for acute and subacute SDH in the elderly patients. METHOD: Between November 2013 and September 2016, a total of 17 patients with acute SDH (15 patients), subacute SDH (1 patient), or acute aggravation of chronic SDH (1 patient) underwent hematoma evacuation with a flexible endoscope at our hospital and were enrolled in this retrospective study. Either under local or general anesthesia, the SDH was removed with a flexible suction tube with the aid of the flexible endoscope through the small craniotomy (3 * 4 cm). Hematoma evacuation rate, improvement of clinical symptoms, and procedure-related complications were evaluated. RESULTS: Hematoma evacuation rate was satisfactory, and statistically significant clinical improvement was observed in postoperative Glasgow Coma Scale in all cases compared to the preoperative assessment. No procedure-related hemorrhagic complications were observed. CONCLUSIONS: The results reported here suggest that small craniotomy evacuation with a flexible endoscope is a safe, effective, and minimally invasive treatment for acute and subacute SDH in selected cases. PMID- 29192374 TI - Impact of Bacterial Translocation on Hepatopulmonary Syndrome: A Prospective Observational Study. AB - BACKGROUND/AIMS: Hepatopulmonary syndrome (HPS) is characterized by a defect in oxygenation induced by pulmonary vascular dilatation in cirrhosis. While severe HPS is responsible for a high rate of mortality, the prevalence and pathophysiology of HPS are not fully elucidated. We evaluated the prevalence and pathophysiology of HPS in patients with cirrhosis. METHODS: A total of 142 patients with cirrhosis who underwent saline-agitated contrast echocardiography were enrolled in this prospective observational study. HPS was defined by positive findings on contrast echocardiography, cirrhosis, and the presence of an oxygenation defect (alveolar-arterial oxygen gradient > 15 mmHg). HPS grades from 0 to 3 were assigned based on the density and spatial distribution of microbubbles in the left ventricle. The primary endpoint was the prevalence of HPS. The secondary endpoints included clinical characteristics and levels of lipopolysaccharide (LPS), LPS-binding protein (LBP), nitric oxide, and endothelin 1 in HPS. RESULTS: Fifty-nine patients (41.5%) were diagnosed with HPS (grade 1: 24, grade 2: 23, and grade 3: 12 patients). The mean levels of LPS (0.36 +/- 0.02, 1.02 +/- 0.18, 2.86 +/- 0.77, and 6.56 +/- 1.46 EU/mL, p < 0.001) and LBP (7026 +/- 3336, 11,445 +/- 1247, 11,947 +/- 1164, and 13,791 +/- 2032 ng/mL, p = 0.045) were found to be increased according to HPS grade (negative, grade 1-3). Endothelin-1 levels were significantly elevated according to HPS grade (1.83 +/- 0.17, 2.62 +/- 0.22, 3.69 +/- 0.28, and 4.29 +/- 0.34 pg/mL, p < 0.001), demonstrating a significant difference between each grade (p < 0.05). CONCLUSIONS: HPS is a common complication with a prevalence of 41.5% in patients with cirrhosis. Bacterial translocation and portal pulmonary vascular dilatation are key mechanism involved in the progression of HPS.

PMID- 29192375 TI - Efficacy of Rebamipide in Organic and Functional Dyspepsia: A Systematic Review and Meta-Analysis. AB - OBJECTIVE: The role of gastritis in dyspepsia remains controversial. We aimed to examine the efficacy of rebamipide, a gastric mucosal protective agent, in both organic and functional dyspepsia. DESIGN: A systematic review and meta-analysis was performed. The following databases were searched using the keywords ("rebamipide" OR "gastroprotective agent*" OR "mucosta") AND ("dyspepsia" OR "indigestion" OR "gastrointestinal symptoms"): PubMed, Wed of Science, Embase, CINAHL, Cochrane Clinical Trials Register. The primary outcome was dyspepsia or upper GI symptom score improvement. Pooled analysis of the main outcome data were presented as risk ratio (RR) for dichotomous data and standardized mean difference (SMD) for continuous data. RESULTS: From an initial 248 records, 17 randomised controlled trial (RCT) publications involving 2170 subjects (1224 rebamipide, 946 placebo/control) were included in the final analysis. Twelve RCTs were conducted in subjects with organic dyspepsia (peptic ulcer disease, reflux esophagitis or NSAID-induced gastropathy) and five RCTs were conducted in patients with functional dyspepsia (FD). Overall, dyspepsia symptom improvement was significantly better with rebamipide compared to placebo/control drug (RR 0.77, 95% CI = 0.64-0.93; SMD -0.46, 95% CI = -0.83 to -0.09). Significant symptom improvement was observed both in pooled RR and SMD in subjects with organic dyspepsia (RR 0.72, 95% CI = 0.61-0.86; SMD -0.23, 95% CI = -0.4 to 0.07), while symptom improvement in FD was observed in pooled SMD but not RR (SMD -0.62, 95% CI = -1.16 to -0.08; RR 1.01, 95% CI = 0.71-1.45). CONCLUSION: Rebamipide is effective in organic dyspepsia and may improve symptoms in functional dyspepsia. PMID- 29192377 TI - How does transient signaling input affect the spike timing of postsynaptic neuron near the threshold regime: an analytical study. AB - The noisy threshold regime, where even a small set of presynaptic neurons can significantly affect postsynaptic spike-timing, is suggested as a key requisite for computation in neurons with high variability. It also has been proposed that signals under the noisy conditions are successfully transferred by a few strong synapses and/or by an assembly of nearly synchronous synaptic activities. We analytically investigate the impact of a transient signaling input on a leaky integrate-and-fire postsynaptic neuron that receives background noise near the threshold regime. The signaling input models a single strong synapse or a set of synchronous synapses, while the background noise represents a lot of weak synapses. We find an analytic solution that explains how the first-passage time (ISI) density is changed by transient signaling input. The analysis allows us to connect properties of the signaling input like spike timing and amplitude with postsynaptic first-passage time density in a noisy environment. Based on the analytic solution, we calculate the Fisher information with respect to the signaling input's amplitude. For a wide range of amplitudes, we observe a non monotonic behavior for the Fisher information as a function of background noise. Moreover, Fisher information non-trivially depends on the signaling input's amplitude; changing the amplitude, we observe one maximum in the high level of the background noise. The single maximum splits into two maximums in the low noise regime. This finding demonstrates the benefit of the analytic solution in investigating signal transfer by neurons. PMID- 29192378 TI - Comparing Parental Well-Being and Its Determinants Across Three Different Genetic Disorders Causing Intellectual Disability. AB - Using the Short Form 12 Health Survey this cross-sectional study examined parental well-being in caregivers of children with one of three genetic disorders associated with intellectual disability; Down syndrome, Rett syndrome and the CDKL5 disorder. Data were sourced from the Western Australian Down Syndrome (n = 291), Australian Rett Syndrome (n = 187) and International CDKL5 Disorder (n = 168) Databases. Among 596 mothers (median age, years 43.7; 24.6-72.2), emotional well-being was poorer than general female populations across age groups. Multivariate linear regression identified the poorest well-being in parents of children with the CDKL5 disorder, a rare but severe and complex encephalopathy, and negative associations with increased clinical severity irrespective of diagnosis.

AB - Children with autism experience challenges with emotion regulation. It is unclear how children's management of their emotions is associated with their family's quality of life. Forty-three preschoolers with autism and 28 typically developing preschoolers were coded on emotion regulation strategies used during low-level stress tasks. Parents reported on their quality of life and family functioning, and their child's internalizing and externalizing behaviors. More externalizing behaviors across groups and use of two emotion regulation strategies (self soothing, deep exhalation) in the autism group predicted lower family quality of life. Findings suggest that children's emotional outbursts and reduced use of passive comforting strategies are linked to lower family quality of life.

PMID- 29192381 TI - ABCB6, an ABC Transporter Impacting Drug Response and Disease. AB - Recent findings have discovered how insufficiency of ATP-binding cassette (ABC) transporter, ABCB6, can negatively impact human health. These advances were made possible by, first, finding that ABCB6 deficiency was the genetic basis for some severe transfusion reactions and by, second, determining that functionally impaired ABCB6 variants enhanced the severity of porphyria, i.e., diseases associated with defects in heme synthesis. ABCB6 is a broad-spectrum porphyrin transporter that is capable of both exporting and importing heme and its precursors across the plasma membrane and outer mitochondrial membrane, respectively. Biochemical studies have demonstrated that while ABCB6 influences the antioxidant system by reducing the levels of reactive oxygen species, the exact mechanism is currently unknown, though effects on heme synthesis are likely. Furthermore, it is unknown what biochemical or cellular signals determine where ABCB6 localizes in the cell. This review highlights the major recent findings on ABCB6 and focuses on details of its structure, mechanism, transport, contributions to cellular stress, and current clinical implications.

AB - The aim of this study was to characterize the in vivo volumetric distribution of three folate-based biosensors by different imaging modalities (X-ray, fluorescence, Cerenkov luminescence, and radioisotopic imaging) through the development of a tridimensional image reconstruction algorithm. The preclinical and multimodal Xtreme imaging system, with a Multimodal Animal Rotation System (MARS), was used to acquire bidimensional images, which were processed to obtain the tridimensional reconstruction. Images of mice at different times (biosensor distribution) were simultaneously obtained from the four imaging modalities. The filtered back projection and inverse Radon transformation were used as main image processing techniques. The algorithm developed in Matlab was able to calculate the volumetric profiles of 99mTc-Folate-Bombesin (radioisotopic image), 177Lu Folate-Bombesin (Cerenkov image), and FolateRSenseTM 680 (fluorescence image) in tumors and kidneys of mice, and no significant differences were detected in the volumetric quantifications among measurement techniques. The imaging tridimensional reconstruction algorithm can be easily extrapolated to different 2D acquisition-type images. This characteristic flexibility of the algorithm developed in this study is a remarkable advantage in comparison to similar reconstruction methods. PMID- 29192384 TI - Spin states of Mn(III) meso-tetraphenylporphyrin chloride assessed by density functional methods. AB - The present work assessed several exchange-correlation functionals (including GGA, meta-GGA and hybrid functionals), in combination with a variety of basis sets and effective core potentials (ECP) for their ability to predict the ground spin state of Mn(III) meso-tetraphenylporphyrin chloride complex, labeled Mn(III)TPPCl, for which experimental data support the quintet high spin state. Geometry optimization of Mn(III)TPPCl was performed for three possible spin states (singlet state, LS; triplet state, IS; and quintet state, HS) at the TPSSh level using the LANL2DZ ECP for Mn and the 6-311G(d) basis set for C, N, Cl and H. Afterwards, single-point energy calculations were conducted by applying 18 exchange-correlation functionals (BLYP, B3LYP, PW91, BPW91, BP86, OLYP, OPBE, OPW91, O3LYP, PBE0, PBEh1PBE, HSEH1PBE, TPSS, TPSSh, M06 L, M06, M062X and M06HF). The influence of the basis set for the metal center was assessed using a smaller group of functionals and varying between the Pople basis set 6-31G(d), its newer formulation m6-31G(d) and the larger Def2-QZVP basis set. All functionals in combination with Pople basis sets predict the quintet state as the ground spin state. In addition, the BLYP, BP86, BPW91, PW91, PBEh1PBE, TPSS and TPSSh functionals predicted the IS lying at most ~60 kJ mol-1 above the HS, which agrees with the reference data. Results including Def2-QZVP basis set were inconsistent, since only BLYP and B3LYP predict HS as the ground spin state. The recommended methodology for the treatment of such systems seems to be exchange correlations functionals with few or none Hartree-Fock exchange and modest size basis sets.

AB - BACKGROUND: Gallstone disease is common after bariatric surgery, and patients with bile duct stones in this cohort can be difficult to treat, due to the altered anatomy. This review aims to analyse the various management options available for choledocholithiasis in post-bariatric surgery patients. METHODS: A literature search of PubMed, Medline and Cochrane library databases was carried out for studies on this subject, between January 1970 and March 2017. After initial screening and further full text review, suitable studies were identified after applying the inclusion criteria. RESULTS: Twenty-nine studies were identified and analysed. Overtube-assisted endoscopy appears to be a popular technique, and 10 studies employing this technique were identified. Though there are minor variations between the three different types of overtube endoscopy, the success rate for ERCP with this approach is between 60 and 70%. Studies using a combination of radiological and endoscopic techniques report a success rate of 60 70%, though the endoscopic ultrasound-guided technique has been reported to have higher success rates (90-100%). Surgery-assisted ERCP also appears to be widely reported and has a consistently high ERCP success rate (80-100%), with an added advantage of the option to perform a concomitant cholecystectomy. There are very few reports on using surgery as the sole option in this scenario. CONCLUSION: Both overtube-assisted endoscopy and laparoscopy-assisted ERCP appear to be safe, with good success rates. The other methods may be suitable for selected patients and centres with specific interest in such techniques. PMID- 29192386 TI - Sequential Neighborhood Effects: The Effect of Long-Term Exposure to Concentrated Disadvantage on Children's Reading and Math Test Scores. AB - Prior research has suggested that children living in a disadvantaged neighborhood have lower achievement test scores, but these studies typically have not estimated causal effects that account for neighborhood choice. Recent studies used propensity score methods to account for the endogeneity of neighborhood exposures, comparing disadvantaged and nondisadvantaged neighborhoods. We develop an alternative propensity function approach in which cumulative neighborhood effects are modeled as a continuous treatment variable. This approach offers several advantages. We use our approach to examine the cumulative effects of neighborhood disadvantage on reading and math test scores in Los Angeles. Our substantive results indicate that recency of exposure to disadvantaged neighborhoods may be more important than average exposure for children's test scores. We conclude that studies of child development should consider both average cumulative neighborhood exposure and the timing of this exposure. PMID- 29192387 TI - Differences in Child Health Across Rural, Urban, and Slum Areas: Evidence From India. AB - The developing world is rapidly urbanizing, but an understanding of how child health differs across urban and rural areas is lacking. We examine the association between area of residence and child health in India, focusing on composition and selection effects. Simple height-for-age averages show that rural Indian children have the poorest health and urban children have the best, with slum children in between. With wealth or observed health environment held constant, the urban height-for-age advantage disappears, and slum children fare significantly worse than their rural counterparts. Hence, differences in composition across areas mask a substantial negative association between living in slums and height-for-age. This association is more negative for girls than boys. Furthermore, a large number of girls are "missing" in slums; we argue that this implies that the negative association between living in slums and health is even stronger than our estimate. The missing girls also help explain why slum girls appear to have a substantially lower mortality than rural girls, whereas slum boys have a higher mortality risk than rural boys. We estimate that slum conditions (such as overcrowding and open sewers), which the survey does not adequately capture, are associated with 20 % to 37 % of slum children's stunting risk.

AB - The enthusiasm about successful novel therapeutic strategies in cancer is often quickly dampened by the development of drug resistance. This is true for targeted therapies using tyrosine kinase inhibitors for EGFR or BRAF mutant cancers, but is also an increasingly recognized problem for immunotherapies. One of the major obstacles of successful cancer therapy is tumor heterogeneity of genotypic and phenotypic features. Historically, drivers for drug resistance have been suspected and found on the genetic level, with mutations either being pre existing in a subset of cancer cells or emerging de novo to mediate drug resistance. In contrast to that, our group and others identified a non-mutational adaptive response, resulting in a reversible, drug tolerant, slow cycling phenotype that precedes the emergence of permanent drug resistance and is triggered by prolonged drug exposure. More recently, studies described the importance of initially reversible transcriptional reprogramming for the development of acquired drug resistance, identified factors important for the survival of the slow cycling phenotype and investigated the relationship of mutational and non-mutational resistance mechanisms. However, the connection and relative importance of mutational and adaptive drug resistance in relation to the in vitro models at hand and the clinically observed response patterns remains poorly defined. In this review we focus on adaptive intrinsic phenotypic plasticity in cancer cells that leads to the drug tolerant slow cycling state, which eventually transitions to permanent resistance, and propose a general model based on current literature, to describe the development of acquired drug resistance. PMID- 29192391 TI - IL-21 as a Predictor of Sustained Virologic Response in Patients with Chronic Hepatitis C Virus Infection. AB - Hepatitis C virus (HCV) infection is a significant public health problem. The crucial role of interleukin (IL)-21 in HCV has been established. Thus, we aimed to investigate the association of serum IL-21 levels with the virological response to interferon (IFN)-based therapy in a group of Egyptian patients with chronic hepatitis C (CHC). Clinical data were collected from 58 HCV-positive Egyptian patients treated with IFN/ribavirin therapy and 10 non-HCV-infected healthy subjects. Liver and renal function tests, complete blood count, viral markers, and pretreatment IL-21 levels were determined in all patients and healthy controls. Patients who achieved sustained virologic response (SVR) had higher pretreatment median serum IL-21 levels than those who did not. Thus, this study concluded that higher pretreatment serum IL-21 may be useful in predicting SVR in CHC patients. PMID- 29192390 TI - EpCAM-based assays for epithelial tumor cell detection in cerebrospinal fluid. AB - The diagnosis of leptomeningeal metastases (LM) of solid tumors is complicated due to low sensitivities of both magnetic resonance imaging (MRI) and cytology. MRI has a sensitivity of 76% for the diagnosis of LM and cerebrospinal fluid (CSF) cytology has a sensitivity of 44-67% at first lumbar puncture which increases to 84-91% upon second CSF sampling. Epithelial cell adhesion molecule (EpCAM) is expressed by solid tumors of epithelial origin like non-small-cell lung cancer, breast cancer or ovarium cancer. Recently, a CELLSEARCH(r) assay and flow cytometry laboratory techniques have been developed to detect circulating tumor cells (CTCs) of epithelial origin in CSF. These laboratory techniques are based on capture antibodies labelled with different fluorescent tags against EpCAM. In this review, we provide an overview of the available laboratory techniques and diagnostic accuracy for tumor cell detection in CSF. The reported sensitivities of the EpCAM-based CTC assays for the diagnosis of LM across the different studies are highly promising and vary between 76 and 100%. An overview of the different EpCAM-based techniques for the enumeration of CTCs in the CSF is given and a comparison is made with CSF cytology for the diagnoses of LM from epithelial tumors.

The device dissolves within the vitreous body and releases dexamethasone. Here we present a clinical case that demonstrates the sustained therapeutic efficacy of Ozurdex(r) when accidentally injected into the crystalline lens. METHODS: Case report. RESULTS: Sixty-three-year-old male in which we decided to prescribe the intravitreal injection of a dexamethasone implant (Ozurdex(r)) in the left eye because of macular oedema after branch retinal vein occlusion. Best-corrected visual acuity (BCVA) was 0.4. At 15 days post-implantation, the slit-lamp examination revealed the dexamethasone implant was located in the crystalline lens. Given there was no inflammation in the anterior pole, no cataracts had developed, the intraocular pressure (IOP) was normal and the macular oedema had been resolved, we decided to assess the efficacy and safety of the dexamethasone implant located in the crystalline lens. The BCVA improved until 14 months post-accidental injection. At 18 months post Ozurdex(r) injection the BCVA worsened until 0.05 because of the cataract evolution. Phacoemulsification and intraocular lens placement in sulcus was performed. CONCLUSION: Once the complication has occurred, most authors advocate the early withdrawal of the implanted Ozurdex(r) device by means of crystalline phacoemulsification and then repositioning it in the vitreous body. However, as long as there are no signs of inflammation in the anterior pole, the IOP is within normal limits, the device does not affect the visual axis and there is no cataract development, we can evaluate the potential therapeutic effect of Ozurdex(r) in this non-indicated, abnormal location. PMID- 29192396 TI - Insights into the Synergistic Biodegradation of Waste Papers Using a Combination of Thermostable Endoglucanase and Cellobiohydrolase from Chaetomium thermophilum. AB - Enzymatic hydrolysis is considered an efficient and environmental strategy for the degradation of organic waste materials. Compared to mesophilic cellulases, thermostable cellulases with considerable activity are more advantageous in waste paper hydrolysis, particularly in terms of their participation in synergistic action. In this study, the synergistic effect of two different types of thermostable Chaetomium thermophilum cellulases, the endoglucanase CTendo45 and the cellobiohydrolase CtCel6, on five common kinds of waste papers was investigated. CtCel6 significantly enhanced the bioconversion process, and CTendo45 synergistically increased the degradation, with a maximum degree of synergistic effect of 1.67 when the mass ratio of CTendo45/CtCel6 was 5:3. The synergistic degradation products of each paper material were also determined. Additionally, the activities of CTendo45 and CtCel6 were found to be insensitive to various metals at 2 mM and 10 mM ion concentrations. This study gives an initial insight into a satisfactory synergistic effect of C. thermophilum thermostable cellulases for the hydrolysis of different paper materials, which provides a potential combination of enzymes for industrial applications, including environmentally friendly waste management and cellulosic ethanol production. PMID- 29192397 TI - Ustekinumab for Treating Moderately to Severely Active Crohn's Disease after Prior Therapy: An Evidence Review Group Perspective of a NICE Single Technology Appraisal. AB - As part of the single technology appraisal (STA) process, the National Institute for Health and Care Excellence (NICE) invited Janssen to submit evidence on the clinical and cost effectiveness of their drug ustekinumab, an interleukin-12/23 inhibitor, for treating moderate-to-severe active Crohn's disease (CD). The Centre for Reviews and Dissemination (CRD) and Centre for Health Economics (CHE) Technology Appraisal Group at the University of York was commissioned to act as the independent Evidence Review Group (ERG). This article provides a description of the Company's submission, the ERG's critical review of submitted evidence, and the resulting NICE guidance. The main supporting clinical evidence was derived from four well conducted, randomised controlled trials, comparing ustekinumab with placebo in two sub-populations (conventional care failure and anti-TNFalpha failure patients) of adults with moderate-to-severe CD. Three trials assessed treatment induction over 8 weeks, while the fourth recruited successfully induced patients into a maintenance trial for 1 year. These trials showed ustekinumab to be more effective than placebo in terms of its ability to induce and maintain clinical response and remission. In the absence of any direct head-to-head data, the Company conducted a network meta-analysis (NMA), which synthesised induction trial data on ustekinumab and relevant comparators (vedolizumab, adalimumab and infliximab) using placebo data as a common comparator. This analysis found ustekinumab to be of comparable efficacy to previously approved biologics in treatment induction. A 'treatment sequence analysis' compared long-term treatment efficacy, finding ustekinumab to be comparable in maintaining treatment response and remission to the three other biologic therapies. However, the ERG had identified many limitations and potential bias in this analysis, and urged caution when interpreting the results. The Company's economic model estimated ustekinumab to be dominant in both sub-populations compared with conventional care; however, the ERG's preferred base-case estimated an incremental cost effectiveness ratio of L109,279 in the conventional care failure sub-population, and L110,967 in the anti-TNFalpha failure sub-population when compared with conventional care. However, the ERG identified significant failings in both the model structure and data inputs, which could not be addressed without complete restructuring. The ERG considered that the economic analysis presented by the Company failed to adequately address the decision problem specified in NICE's scope. The NICE Appraisal Committee recommended ustekinumab within its market authorisation, on the grounds of sufficiently similar efficacy and costs to previously recommended biologic therapies. However, the ERG's analyses demonstrated that all currently recommended biologics are unlikely to be cost effective relative to conventional care, raising broader questions regarding the appropriateness of cost-comparison exercises for decision making. PMID- 29192398 TI - Water quality in simulated eutrophic shallow lakes in the presence of periphyton under different flow conditions. AB - Although the effects of periphyton on water quality and its relationship with flow conditions have been studied by researchers, our understanding about their combined action in eutrophic shallow lakes is poor. In this research, four aquatic model ecosystems with different water circulation rates and hydraulic conditions were constructed to investigate the effect of periphyton and flow condition on water quality. The concentrations of NH4+, TP, and chlorophyll-a and flow conditions were determined. The results show that, as a result of the rising nutrient level at the early stage and the decline in the lower limit, the presence of periphyton can make the ecosystem adaptable to a wider range of nutrients concentration. In terms of the flow condition, the circulation rate and hydraulic condition are influential factors for aquatic ecosystem. Higher circulation rate in the ecosystem, on one hand, facilitates the metabolism by accelerating nutrient cycling which is beneficial to water quality; on the other hand, high circulation rate leads to the nutrient lower limit rising which is harmful to water quality improvement. At low velocities, slight differences in hydraulic conditions, vertical velocity gradient and turbulence intensity gradient could affect the quantity of phytoplankton. Our study suggests that, considering environmental effect of periphyton, flow conditions and their combined action is essential for water quality improvement and ecological restoration in eutrophic shallow lakes.

AB - According to literature data, some of the main factors which significantly affect the quality of the indoor environment in residential households or apartments are human activities such as cooking, smoking, cleaning, and indoor exercising. The paper presents a literature overview related to air quality in everyday use spaces dedicated to specific purposes which are integral parts of residential buildings, such as kitchens, basements, and individual garages. Some aspects of air quality in large-scale car parks, as a specific type of indoor environment, are also discussed. All those areas are characterized by relatively short time use. On the other hand, high and very high concentration levels of xenobiotics can be observed, resulting in higher exposure risk. The main compounds or group of chemical compounds are presented and discussed. The main factors influencing the type and amount of chemical pollutants present in the air of such areas are indicated. PMID- 29192400 TI - Historical anthropogenic mercury in two lakes of Central Chile: comparison between an urban and rural lake. AB - Mercury concentrations in the environment tend to decrease in recent years due to environmental restrictions. Lakes store mercury in their sediments, making them potential secondary contamination sources. In South America, the occurrence of mercury in lake systems has been associated mainly with volcanic emissions and only few records anthropogenic contamination in the pre-Hispanic period. The objective of this research was to study historical anthropogenic mercury concentration in two lakes in Central Chile (La Senoraza and Pillo), in order to establish background mercury levels and their variations from preindustrial to modern periods. Different background levels and mercury concentrations were found in each lake, with significantly higher concentrations in Lake La Senoraza during the last 150 years. Mining-related activities during the nineteenth century could have a negligible influence on mercury concentrations. Later on, the use of coal railroads and subsequent employment of mercury in the cellulose industry were associated with three- and fourfold increases in mercury concentration over the nineteenth century background levels, which decrease once these activities ceased. However, in the case of Lake Pillo, an important increase in mercury concentration can be observed between 1990 and the early twenty-first century, which could be related to a higher watershed/lake area ratio, extensive agriculture, and volcanic emission, being the latter that could have contributed with mercury to both systems. Nevertheless, sedimentological characteristics in Lake Pillo can be favorable to retain mercury in this aquatic system up to the present day. PMID- 29192401 TI - Spatio-temporal evaluation of emerging contaminants and their partitioning along a Brazilian watershed. AB - The occurrence, partitioning, and spatio-temporal distribution of seven pharmaceuticals for human use, three steroid hormones and one personal care product were determined in surface water, suspended particulate matter (SPM), and sediment of Pirai Creek and Jundiai River (Jundiai River Basin, Sao Paulo, Brazil). The maximum average detected concentrations of the compounds in the Pirai River samples were < 30 ng L-1, except for caffeine (222 ng L-1). In Jundiai River samples, most of the compounds were frequently detected, wherein caffeine had the highest concentration, with maximum average concentrations of 14,050 ng L-1, followed by atenolol (431 ng L-1), ibuprofen (268 ng L-1) and diclofenac (214 ng L-1). Atenolol, propranolol, estrone, and triclosan were the contaminants most frequently detected in sediment and SPM samples. Triclosan had the highest average proportion of SPM as opposed to in the aqueous phase (> 75%). Contaminants with acid functional groups showed, in general, a lower tendency to bind to particulate matter and sediments. In addition, hydrophobicity had an important effect on their environmental partitioning. The spatial distribution of contaminants along the Jundiai River was mainly affected by the higher concentration of contaminants in water samples collected downstream from a sewage treatment plant (STP). The results obtained here clearly showed the importance of the analysis of some contaminants in the whole water, meaning both dissolved and particulate compartments in the water, and that the partitioning is ruled by a set of parameters associated to the physicochemical characteristics of contaminants and the matrix properties of the studied, which need be considered in an integrated approach to understand the fate of emerging chemical contaminants in aquatic environments.

AB - In the present experimental analysis, two non-edible oils namely neem oil and pumpkin seed oil were considered. They are converted into respective biodiesels namely neem oil methyl ester (B1) and pumpkin seed oil methyl ester (B2) through transesterification process and their physical and chemical properties were examined using ASTM standards. Diesel was used as a baseline fuel in Kirloskar TV1 model direct injection four stroke diesel engine. A fuel preheater was designed and fabricated to operate at various temperatures (60, 70, and 80 degrees C). Diesel showed higher brake thermal efficiency (BTE) than biodiesel samples. Lower brake specific fuel consumption (BSFC) was obtained with diesel than B1 sample. B1 exhibited lower BSFC than B2 sample without preheating process. High preheating temperature (80 degrees C) results in lower fuel consumption for B1 sample. The engine emission characteristics like carbon monoxide (CO), hydrocarbon (HC), and smoke were found lower with B1 sample than diesel and B2 except oxides of nitrogen (NOx) emission. In preheating of fuel, B1 sample with high preheating temperature showed lower CO, HC, and smoke emission (except NOx) than B2 sample. PMID- 29192403 TI - Transformation of sulfaquinoxaline by chlorine and UV light in water: kinetics and by-product identification. AB - Sulfaquinoxaline (SQX) is an antimicrobial of the sulfonamide class, frequently detected at low levels in drinking and surface water as organic micropollutant. The main goal of the present study is the evaluation of SQX reactivity during chlorination and UV irradiations which are two processes mainly used in water treatment plants. The SQX transformation by chlorination and UV lights (254 nm) was investigated in purified water at common conditions used for water disinfection (pH = 7.2, temperature = 25 degrees C, [chlorine] = 3 mg L-1). The result shows a slow degradation of SQX during photolysis compared with chlorination process. Kinetic studies that fitted a fluence-based first-order kinetic model were used to determine the kinetic constants of SQX degradation; they were equal to 0.7 * 10-4 and 0.7 * 10-2 s-1corresponding to the half time lives of 162 and 1.64 min during photolysis and chlorination, respectively. In the second step, seven by-products were generated during a chlorination and photo transformation of SQX and identified using liquid chromatography with electrospray ionization and tandem mass spectrometry (MS-MS). SO2 extrusion and direct decomposition were the common degradation pathway during photolysis and chlorination. Hydroxylation and isomerization were observed during photodegradation only while electrophilic substitution was observed during chlorination process.

AB - The formulation factors relevant to developing immediate and controlled release dosage forms containing poorly soluble drugs dispersed in amorphous systems are poorly understood. While the utility of amorphous solid dispersions is becoming apparent in the pharmaceutical marketplace, literature reports tend to concentrate on the development of solid dispersion particulates, which then must be formulated into a tablet. Amorphous solid dispersions of itraconazole in high molecular weight hydroxypropyl methylcellulose were prepared by KinetiSol(r) Dispersing and tablets were formulated to immediately disintegrate or control the release of itraconazole. Formulated tablets were evaluated by two non-sink dissolution methodologies and the dosage form properties that controlled the gelling tendency of the dispersion carrier, hydroxypropyl methylcellulose, were investigated. Selected formulations were evaluated in an exploratory beagle dog pharmacokinetic study; the results of which indicate potential for a prolonged absorption phase relative to the commercially extruded control. PMID- 29192404 TI - Effects of lead, cadmium, chromium, and arsenic on the sorption of lindane and norfloxacin by river biofilms, particles, and sediments. AB - The sorption of both classic and emerging organic contaminants onto aquatic solids is a critical process that controls their fate in natural waters. Sorption is affected by numerous factors, including coexisting heavy metals. The mechanisms of the influence of heavy metals, especially those occurring in acid radical anions, are still unclear. Here, the effects of Pb, Cd, Cr, and As on the sorption of lindane and norfloxacin (NOR) onto natural biofilms, suspended particles, and sediments from one river were investigated following batch equilibration methods. In addition, changes in representative components that have important roles in sorption from these solids in the presence and absence of metals were characterized by spectrum analyses. The results indicated that sorption of lindane and NOR on the three solids in the absence of heavy metals was highly linear and nonlinear, respectively. Pb and Cd promoted and Cr and As suppressed hydrophobic lindane sorption on the three solids. This was because Pb and Cd enhanced but Cr and As weakened the hydrophobicity of these solids. Pb, Cd, Cr, and As decreased NOR sorption on sediments and suspended particles at pH 5.7~6.3. This was due to electrostatic competition between cationic Pb/Cd and NORH2+, and the combination of Cr/As acid radicals with NORH2+, which suppressed its ion-exchange adsorption. Pb, Cd, Cr, and As generally increased the sorption of NOR onto the biofilms at pH 5.7~6.3. Pb and Cd strengthened the flocculation of dissolved organic matter combined with NORH2+ onto the biofilms. Cr and As enhanced the hydrophilicity of biofilms, and then increased their sorption of NOR with active hydrophilic groups. The mechanisms of how different heavy metals affect NOR sorption by biofilms were more complicated than the mechanisms affecting lindane sorption, as well as by sediments and particles.

AB - Adipose-derived mesenchymal stem cells (ADSCs) are useful cell model to study adipogenesis and energy metabolism. However, the biological characteristics of bovine ADSCs (bADSCs) remain unclear. This study aimed to isolate and identify bADSCs and further investigate fatty acid (FA)-related gene expression and composition of FAs during adipogenesis. The growth curve showed the bADSCs of P5 cells had rapid proliferation superior to P10-P50. The colony formation assay showed colony number of P5 cells was higher than that of P50 cells (51.67 +/- 3.06 vs 35.67 +/- 6.43, P < 0.05). The immunofluorescence showed that bADSCs were positive for CD13, CD44, CD49d, CD90, CD105, and Vimentin while negative for CD34. The multipotential towards adipocyte, osteocyte, and chondrocyte was confirmed by specific histological staining and lineage gene expression. During adipogenic induction, the genes related to lipogenesis and lipolysis were assessed by real-time PCR and the FA composition was detected by GC-MS. Expression of lipogenesis-related genes showed coordinated regulation as peaking on day 7 and declining until induction ended, including PPARgamma, SREBP1, ACC1, FAS, ELOVL6, SCD1, and FABP4. FA deposition-related genes (DGAT1 and ACAT1) increased until day 14. Lipolysis genes (CPT-1A, VLCAD, and ACO) showed a variant expression pattern. The profile of FAs showed that proportion of the FAs (C4-C15, >= C22) increased, but proportion of long-chain fatty acids (C16-C20) reduced after induction. And saturated FAs (SFA) decreased while monounsaturated FAs (MUFA) and polyunsaturated FAs (PUFA) increased during adipogenesis. These data suggest that bADSCs possess the characteristics of mesenchymal stem cells and have active de novo lipogenesis (DNL) and desaturation of FAs during adipogenesis.

AB - Bone morphogenetic protein 2 (BMP-2) is a potent inducer of bone formation that is currently used in a limited number of clinical indications to treat extensive bone loss. Extending the field of applications of this molecule requires design of the delivery system to protect the protein from early degradation and allow a slow long-term release. This study describes the use of a non-polymer hydrogel, based on the self-assembly of small amphiphilic glycosyl-nucleolipids into micellar structures, as a new type of delivery system for BMP-2. BMP-2 was readily encapsulated in glycosyl-nucleosyl-fluorinated (GNF)-based gels and slowly released in vitro, while maintaining its osteogenic activity. When hydrogel pieces containing fluorophore-tagged BMP-2 were deposited onto a calvaria defect in mouse, the signal detected in living mice gradually decreased and was still detectable at 3 weeks. Gel-embedded protein promoted significant calvarial bone defect regeneration at 8 weeks after surgery. In contrast, when a solution of BMP-2 without hydrogel was injected into the defects, the fluorescence signal decreased rapidly and no significant bone formation was observed. The unique property of the GNF-based hydrogel as an injectable delivery system for low doses of BMP-2 was revealed in a subcutaneous model of ectopic bone formation. Injected BMP-2-laden GNF hydrogel blocks elicited the formation of cancellous bone, showing all the typical features of remodeling bone that contains bone marrow. These results show that this GNF-based hydrogel is an easy to-use, efficient delivery system for BMP-2 and osteogenic material to support bone regeneration.

AB - OBJECTIVE: A number of programs representing virtual patients for use in teaching settings have been developed in the field of psychiatry; however, they simulate only the interview process, not the entire scope of treatment. The authors have developed software through which students can experience the practice of psychiatry (in particular, with dementia patients) in its entirety. This study compares this software with conventional learning methods. METHOD: The control group was 43 fifth-year medical students in 2014 who studied using a conventional learning method (taking lectures and being in contact with actual patients). The experimental group was 36 fifth-year medical students in 2015 that used computer software (taking lectures and with reduced time in contact with actual patients). The authors compared the two groups. Each group was tested before and after clinical training on their acquisition of knowledge of dementia. The control group was tested in 2014, and the experimental group was tested in 2015. RESULTS: The difference in average test scores between the two groups was statistically significant (p = 0.01), with the experimental group scoring higher. CONCLUSIONS: The results indicate that students who were taught using a computer-based software method were better able to answer a standard series of questions designed to evaluate their understanding of dementia than those who were taught in a conventional manner. This study demonstrated that there is a possibility to improve education in the field of psychiatry using a comprehensive clinic simulator. PMID- 29192411 TI - Increased serum neuregulin 4 levels in women with polycystic ovary syndrome: A case-control study. AB - Neuregulin 4 (NRG4) is an adipokine that is synthesized in many tissues and has been shown to be associated with the development of obesity and metabolic disorders in animals and humans. The aim of this study is to investigate the relationship between serum NRG4 levels and various metabolic parameters in women with PCOS. This cross-sectional study included 40 women with PCOS and 40 age- and BMI-matched controls without PCOS. NRG4, fasting blood glucose (FBG), insulin, hs CRP, LDL-C, HDL-C, SHBG, DHEA-SO4 and total-testosterone levels were measured in all the participants. HOMA-IR was used to calculate the insulin resistance. Serum NRG4 levels were higher in women with PCOS than in healthy women (24.89 +/- 9.32 [ng/mL] vs. 18.98 +/- 6.40 [ng/mL], p = 0.002). FBG, LDL-C, HDL-C, LH, SHBG, FAI, DHEA-SO4, insulin, hs-CRP, HOMA-IR and total-testosterone levels were significantly higher in women with PCOS than controls. Circulating NRG4 levels were positively correlated with HOMA-IR, insulin and hs-CRP for both groups. There was a positive correlation between NRG4 and FBG in the PCOS group. HOMA-IR and hs-CRP were associated with NRG4. The high concentration of circulating NRG4 in PCOS may be associated with insulin resistance and low-grade chronic inflammation. PMID- 29192412 TI - Safety and efficacy of using advanced electrosurgical bipolar vessel sealing during vaginal hysterectomy in morbidly obese patients: a retrospective cohort analysis. AB - OBJECTIVES: To assess the safety and efficacy of electrosurgical bipolar vessel sealing during vaginal hysterectomy in morbidly obese patients MATERIAL AND METHODS: A total of 105 morbidly obese patients who underwent vaginal hysterectomy due to benign gynecologic pathologies between January 2010 and April 2017 were included in the study. Patients were divided into two groups according to whether conventional suture ligation technique (n = 64) or electrosurgical bipolar vessel sealing (n = 41) were used during vaginal hysterectomy. The surgical procedure was performed with the same technique in both study groups. The primary outcomes were duration of surgery and estimated blood loss. The secondary outcomes were intra-operative complications and post-operative complications. RESULTS: The duration of surgery and estimated blood loss in the vessel sealing group was significantly less than in the conventional suture group (p < 0.05). No significant difference was present between the two groups in the rate of intra-operative and post-operative complications. CONCLUSIONS: The primary outcome of our study is that the EBVS system can be used equally and even more effectively in some aspects; and as safe an alternative approach to conventional suture ligation technique during vaginal hysterectomies performed specifically on morbidly obese patients with reduced operation times and blood loss, and without increasing the complication rates. PMID- 29192413 TI - Dysregulation of microRNAs in triple-negative breast cancer. AB - OBJECTIVES: Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with limited treatment options and poor prognosis. TNBC is usually diagnosed at a relatively young age and is characterized by high risk of developing metastases. Some epigenetic regulation of gene expression is associated with TNBC. Expression of microRNAs (miRNAs) can serve as a potential tool for identifying critical biomarkers in TNBC. The aim of our study is to examine expression of selected miRNAs in TNBC and to assess the relationship between miRNA expression and clinicopathological factors. MATERIAL AND METHODS: Expression levels of 19 selected miRNAs were compared between cancerous and normal breast tissues by use of qPCR method. We have evaluated the relationship between the expression level of miRNAs and clinicopathological factors such as: age, tumor size and lymph node status. RESULTS: We found that in TNBC tissues, when compared with normal breast tissues, the expression of miR-190a, miR- 136-5p and miR-126-5p was significantly reduced (p = 0.0041, p = 0.0007, p = 0.0007, respectively) whereas expression of miR-135b-5p and miR-182-5p was significantly increased (p = 0.0194, p = 0.0041, respectively). We found a linear trend for tumor size and expression of miR-126-5p (p = 0.0296) and miR-135b-5p (p = 0.0241). CONCLUSIONS: Our study confirms that miRNA expression profile is dysregulated in TNBC patients compared to healthy controls. MiR-190a, miR-136-5p, miR-126-5p, miR-135b-5p and miR-182-5p may be associated with development and progression of TNBC. PMID- 29192414 TI - Outcomes of patients with advanced stage ovarian cancer with intestinal metastasis. AB - OBJECTIVES: The aim of this study is to evaluate the results of advanced stage (stage IIIB-IVB) ovarian cancer (OC) patients with intestinal metastasis, and to investigate the factors that affect survival. MATERIAL AND METHODS: Patients who underwent cytoreductive surgery (CS) for FIGO stage IIIB-IVB OC with metastasis in the intestinal system, at Tepecik Research and Treatment Hospital between 2008 2014, were analyzed retrospectively. Patients with borderline ovarian tumor; those who had previously undergone radiation therapy and/or hysterectomy and patients having secondary or tertiary cytoreduction were excluded and 49 patients were included and analyzed in this study. Hysterectomy, bilateral salpingo oopherectomy, pelvic and para-aortic lymph node sampling, resection of bulky lymph nodes and omentectomy were performed. Optimal cytoreduction was accepted as that which left residual tumor <= one cm maximum size. RESULTS: The risk factors affecting OS interval were investigated according to Cox' regression analysis. Optimality of the primary CS (P = 0.008 and HR = 5.202) and cancer stage (P = 0.016 and HR = 6.083) were found to be statistically significant factors. CONCLUSIONS: Achieving optimal CS is the most important aim for the general surgeon carrying out an intestinal resection procedure. Although resection procedures are superior in providing the desired optimal results when compared to excision surgery, their higher complication rates and subsequent lower quality of life must be taken into consideration when choosing either resection or excision methods; surgical intervention should always be kept to the minimum possible. PMID- 29192415 TI - DNA methyltransferase inhibitors influence on the DIRAS3 and STAT3 expression and in vitro migration of ovarian and breast cancer cells. AB - OBJECTIVES: Downregulation of DIRAS3 (DIRAS family, GTP-binding Ras-like 3) is related to ovarian and breast cancer progression. A possible mechanism that silences this gene is the promoter region DNA methylation. The potential reversibility of this epigenetic mechanism makes it more attractive candidate for new mode of cancer treatment. DIRAS3 regulates cell cycle, tumor dormancy and inhibits cancer cell growth and motility, all of which may indirectly depend on interaction with STAT3 (Signal Transducer and Activator of Transcription 3) classified as a potential oncogene. The restoration of DIRAS3 expression could inhibit cell proliferation and invasiveness. MATERIAL AND METHODS: Human ovarian carcinoma cell line (A2780) and human breast cancer cell line (MCF7) were exposed to two DNA methyltransferase inhibitors (DNMTi): decitabine (5-aza-2' deoxycytidine) [25 MUM and 12.5 MUM] and RG108 [150 MUM and 100 MUM]. In vitro migration changes of cancer cells were examined with wound healing assay. After 7 days of DNMTi treatment cells were harvested and DNA and RNA was isolated. The methylation status of the promoter sequences of DIRAS3 and STAT3 genes was determined using methylation specific PCR (MS-PCR). Level of target genes' expression was quantified using quantitative reverse transcription PCR (QRT-PCR). RESULTS AND CONCLUSIONS: The in vitro wound healing assay showed changes in the migration rate of both adherent cell lines after DNMTi treatment compared to the untreated cells. Relative balance between methylated and unmethylated variants of DIRAS3 after MS-PCR was shifted towards unmethylated version after DNMTi treatment in A2780 cells. Statistically significant dose dependent effect of decitabine and RG108 on DIRAS3 expression in A2780 cells was observed. PMID- 29192416 TI - Mig-7 expression and vasculogenic mimicry in malignant ovarian tumors. AB - OBJECTIVES: To investigate the possible association of vasculogenic mimicry (VM), VE-cadherin and MIG-7 expression with clinicopathological features of women with malignant ovarian masses. MATERIAL AND METHODS: VM was studied with the PAS reaction and VE-cadherin was assessed with immunohistochemistry in 108 women with malignant ovarian tumors. Additionally, quantitative expression of MIG-7 mRNA was performed in 52 ovarian cancers with qRT-PCR. RESULTS: VM was found in 48/108 cases (44%), more often in higher FIGO stage tumors (83% cases; 40 vs. 8; p = 0.01). High expression of VE-cadherin was present in 37% of all ovarian masses. Ovarian tumors without VM more often expressed low levels of VE-cadherin than tumors where VM was found (37.6% vs.14.6%). No expression or very low expression of MIG-7 mRNA was found in all normal ovarian tissues and in 32 cancer samples. Median RQ of MIG-7 mRNA in tumor samples was higher than in normal ovarian tissue (RQ = 0.29 vs. RQ = 0.05, respectively; p < 0.005) and higher than in non malignant ovarian masses (0.98 vs. 0.05 respectively; p = 0.03). Expression of MIG-7 mRNA was significantly correlated with VM (p = 0.039). In tumors with PAS positive structures median RQ MIG-7 mRNA was higher than in tumors with PAS negative findings (1.89 vs. 0.13 respectively). VE-cadherin expression was more frequently found in tumors where MIG-7 mRNA was present (p = 0.004). CONCLUSIONS: Vasculogenic mimicry exists in malignant ovarian tumors and advanced clinical stages of malignancy are accompanied by a high incidence of VM formation. MIG-7 mRNA and VE-cadherin expression may serve as additional molecular markers of VM in ovarian malignancies. PMID- 29192417 TI - Diagnostic hysteroscopy and the risk of malignant cells intraabdominal spread in women with endometrial cancer. AB - Although hysteroscopy is currently the undisputed gold standard for the examination of the uterine cavity in women with suspected endometrial cancer, it remains controversial as a procedure that can enhance metastasis spread. Endometrial cancer cells may shed during hysteroscopy and be passively transported with fluid flow into the peritoneal cavity. The paper presents the review of current knowledge regarding the risk of neoplasm metastases in women who had diagnostic hysteroscopy and the conditions that have to be met for the procedure to be safe. We searched PubMed, Ovid, Medline and Scopus databases for data published in the years 1985-2017. The following browsing criteria, the "MeSH headings": hysteroscopy, endometrial cancer, intraperitoneal or metastatic spread were used to find relevant papers. Based on the current data analysis we conclude that (1.) diagnostic hysteroscopy performed in women with endometrial cancer, especially in its early stages, is a very useful, efficient and safe diagnostic method and (2.) the distension media used for endoscopic procedures in the uterine cavity must be strictly controlled for relatively low pressures to prevent the increase in risk of endometrial cancer intraperitoneal spread. PMID- 29192418 TI - Novel biomarkers of overactive bladder syndrome. AB - The social aspect of overactive bladder syndrome (OAB) and the lack of objective diagnostic methods for this syndrome have spurred research into its potential biomarkers which can constitute useful diagnostic tools, while also allowing the evaluation of the intensity of clinical symptoms and the efficacy of implemented pharmacotherapy in OAB patients. Due to the complex etiopathogenesis of this syndrome, the researchers are seeking biomarkers connected with inflammation or nerve growth. The aim of this review was to analyse the latest literature data regarding potential biomarkers in OAB. The most promising opportunities are connected with the diagnostic use of the nerve growth factor (NGF), the brain derived neurotrophic factor (BDNF), C-reactive protein (CRP), prostaglandins and cytokines. Despite the most promising results to date having been obtained with regards to neurotrophic factors, it seems that, at the moment, none of these meets the criteria for becoming an isolated OAB marker. It is also suggested that the combined use of several biomarkers will facilitate obtaining the appropriate level of specificity and selectivity to allow their use in clinical practice.

Infection is transmitted when an infected female mosquito bites a human introducing the sporozoites into human blood. The article presents the course of pregnancy and delivery in a patient complicated by Plasmodium infection. The patient had repetitive several trips to Tanzania over a short time period before she developed the condition. She had been taking antimalarial medication (proguanil atovaquone) in a prophylactic dose during and after her first travel to Tanzania. Following her first return to Poland she experienced infection-related symptoms. PMID- 29192420 TI - Use of a levonorgestrel-releasing intrauterine device for menorrhagia treatment during adjuvant therapy of adrenocortical carcinoma with mitotane. AB - Adrenocortical carcinoma is a rare tumour with high malignancy and poor prognosis. This tumour is rarely diagnosed in the reproductive age. Complete surgical resection is the only curative treatment for adrenal cancer in all stages. After surgery adjuvant chemotherapy is required. Mitotane is the most important drug in adrenal cancer chemotherapy. Mitotane's mode of action is not entirely explained. Animal studies have shown that the substance exerts a direct cytotoxic effect on the cells of the adrenal cortex. This activity is selective, progressive and affects only the zona reticularis and fasciculata of the adrenal cortex. Mitotane inhibits cortisol synthesis by disrupting the chain of cholesterol. It has been suggested, that mitotane also affects the peripheral metabolism of steroids, especially of transcortin (CBG). This results in an increase of CBG blood concentration and a reduction of the amount of free hormones. PMID- 29192421 TI - The state of critical care ultrasound training in Europe: A survey of trainers and a comparison of available accreditation programmes. AB - BACKGROUND: Although critical care ultrasound (CCUS) in the Intensive Care Unit has been increasing exponentially for diagnostic and therapeutic purposes, the lack of a uniform formal training structure and programme has posed the question of whether scans have been appropriately performed or reported, and whether there exists proper clinical governance to ensure a high standard of care. METHODS: An online survey was sent to the representatives of various national intensive care societies via the European Society of Intensive Care Medicine CoBaTrICE committee. A comparison between 5 worldwide accreditation programmes was also made. RESULTS: Twenty-seven out of 42 countries replied our survey. Five countries had a nationally accredited programme in ICM Echocardiography while six were in the process of developing one. Three countries had a CCUS-accredited programme. Most had local programmes. Transthoracic echocardiography, lung and vascular ultrasound were considered essential. Although CCUS training programmes should incorporate a combination of theoretical and practical teaching, it is not clear which is the best format. The main barriers to delivering CCUS training included a lack of formally agreed competencies, as well as a lack of trainers and time. There is also a lack of agreement between the five accreditation programmes. CONCLUSIONS: There is a need for a well-structured and competent CCUS training program. The use of ultrasound in critical care for diagnostic and therapeutic purposes has been increasing exponentially. Once the remit of radiologists and cardiologists, point-of-care ultrasound and focused echocardiography is becoming an increasingly routine instrument for all acute specialties including intensive care medicine, despite the lack of evidence that it improves patient mortality in the ICU setting. PMID- 29192422 TI - Executive summary on the use of ultrasound in the critically ill: consensus report from the 3rd Course on Acute Care Ultrasound (CACU). AB - Over the past decades, ultrasound (US) has gained its place in the armamentarium of monitoring tools in the intensive care unit (ICU). Critical care ultrasonography (CCUS) is the combination of general CCUS (lung and pleural, abdominal, vascular) and CC echocardiography, allowing prompt assessment and diagnosis in combination with vascular access and therapeutic intervention. This review summarises the findings, challenges lessons from the 3rd Course on Acute Care Ultrasound (CACU) held in November 2015, Antwerp, Belgium. It covers the different modalities of CCUS; touching on the various aspects of training, clinical benefits and potential benefits. Despite the benefits of CCUS, numerous challenges remain, including the delivery of CCUS training to future intensivists. Some of these are discussed along with potential solutions from a number of national European professional societies. There is a need for an international agreed consensus on what modalities are necessary and how best to deliver training in CCUS. PMID- 29192423 TI - Bisphosphonates for Paget's disease of bone in adults. AB - BACKGROUND: Bisphosphonates are considered to be the treatment of choice for people with Paget's disease of bone. However, the effects of bisphosphonates on patient-centred outcomes have not been extensively studied. There are insufficient data to determine whether reducing and maintaining biochemical markers of bone turnover to within the normal range improves quality of life and reduces the risk of complications. OBJECTIVES: To assess the benefits and harms of bisphosphonates for adult patients with Paget's disease of bone. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, ISI Web of Knowledge and trials registers up to March 2017. We searched regulatory agency published information for rare adverse events. SELECTION CRITERIA: Randomised controlled trials (RCTs) of bisphosphonates as treatment for Paget's disease in adults. DATA COLLECTION AND ANALYSIS: Two review authors independently screened search results, extracted data and assessed studies for risk of bias. We used standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS: We included 20 trials (25 reports, 3168 participants). Of these, 10 trials (801 participants) compared bisphosphonates (etidronate, tiludronate, ibandronate, pamidronate, olpadronate, alendronate, risedronate, zoledronate) versus placebo, seven compared two bisphosphonates (992 participants), one trial compared a bisphosphonates with a bisphosphonate plus calcitonin (44 participants), and two studies, the largest trial (1331 participants) and its interventional extension study (502 participants), compared symptomatic treatment and intensive treatment where the goal was to normalise alkaline phosphatase.Most studies were assessed at low or unclear risk of bias. Six of 10 studies comparing bisphosphonates versus placebo were assessed at high risk of bias, mainly around incomplete outcome data and selective outcome reporting.Participant populations were reasonably homogeneous in terms of age (mean age 66 to 74 years) and sex (51% to 74% male). Most studies included participants who had elevated alkaline phosphatase levels whether or not bone pain was present. Mean follow-up was six months.Bisphosphonates versus placeboBisphosphonates tripled the proportion (31% versus 9%) of participants whose bone pain disappeared (RR 3.42, 95% confidence interval (CI) 1.31 to 8.90; 2 studies, 205 participants; NNT 5, 95% CI 1 to 31; moderate-quality evidence). This result is clinically important. Data were consistent when pain change was measured as any reduction (RR 1.97, 95% CI 1.29 to 3.01; 7 studies, 481 participants).There was uncertainty about differences in incident fractures: 1.4% fractures occurred in the bisphosphonates group and none in the placebo group (RR 0.89, 95% CI 0.18 to 4.31; 4 studies, 356 participants; very low-quality evidence).None of the studies reported data on orthopaedic surgery, quality of life or hearing thresholds.Results regarding adverse effects and treatment discontinuation were uncertain. There was a 64% risk of mild gastrointestinal adverse events in intervention group participants and 48% in the control group (RR 1.32, 95% CI 0.91 to 1.92; 6 studies, 376 participants; low quality evidence). The likelihood of study participants discontinuing due to adverse effects was slightly higher in intervention group participants (4.4%) than the control group (4.1%) (RR 1.01, 95% CI 0.41 to 2.52; 6 studies, 517 participants; low-quality evidence). Zoledronate was associated with an increased risk of transient fever or fatigue (RR 2.57, 95% CI 1.21 to 5.44; 1 study, 176 participants; moderate-quality evidence).Bisphosphonates versus active comparatorMore participants reported pain relief with zoledronate than pamidronate (RR 1.30, 95% CI 1.10 to 1.53; 1 study, 89 participants; NNT 5, 95% CI 3 to 11) or risedronate (RR 1.36, 95% CI 1.06 to 1.74; 1 study, 347 participants; NNT 7, 95% CI 4 to 24; very low quality evidence). This result is clinically important.There was insufficient evidence to confirm or exclude differences in adverse effects of bisphosphonates (RR 1.05, 95% CI 0.95 to 1.76; 2 studies, 437 participants; low-quality evidence) and treatment discontinuation (2 studies, 437 participants) (RR 2.04, 95% CI 0.43 to 9.59; 2 studies, 437 participants; very low-quality evidence).Intensive versus symptomatic treatmentThere was no consistent evidence of difference to response in bone pain, bodily pain or quality of life in participants who received intensive versus symptomatic treatment.Inconclusive results were observed regarding fractures and orthopaedic procedures for intensive versus symptomatic treatment (intensive treatment for fracture: RR 1.84, 95% CI 0.76 to 4.44; absolute risk 8.1% versus 5.2%; orthopaedic procedures: RR 1.58, 95% CI 0.80 to 3.11; absolute risk 5.6% versus 3.0%; 1 study, 502 participants; low-quality evidence).There was insufficient evidence to confirm or exclude an important difference in adverse effects between intensive and symptomatic treatment (RR 1.05, 95% CI 0.79 to 1.41; low-quality evidence).There was insufficient evidence to confirm or exclude an important difference of risk of rare adverse events (including osteonecrosis of the jaw) from the regulatory agencies databases. AUTHORS' CONCLUSIONS: We found moderate-quality evidence that bisphosphonates improved pain in people with Paget's disease of bone when compared with placebo. We are uncertain about the results of head-to-head studies investigating bisphosphonates. We found insufficient evidence of benefit in terms of pain or quality of life from intensive treatment. Information about adverse effects was limited, but serious side effects were rare, and rate of withdrawals due to side effects was low. PMID- 29192424 TI - Interventions for Old World cutaneous leishmaniasis. AB - BACKGROUND: Cutaneous leishmaniasis, caused by a parasitic infection, is considered one of the most serious skin diseases in many low- and middle-income countries. Old World cutaneous leishmaniasis (OWCL) is caused by species found in Africa, Asia, the Middle East, the Mediterranean, and India. The most commonly prescribed treatments are antimonials, but other drugs have been used with varying success. As OWCL tends to heal spontaneously, it is necessary to justify the use of systemic and topical treatments. This is an update of a Cochrane Review first published in 2008. OBJECTIVES: To assess the effects of therapeutic interventions for the localised form of Old World cutaneous leishmaniasis. SEARCH METHODS: We updated our searches of the following databases to November 2016: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trials registers and checked the reference lists of included studies for further references to relevant randomised controlled trials (RCTs). We wrote to national programme managers, general co-ordinators, directors, clinicians, WHO-EMRO regional officers of endemic countries, pharmaceutical companies, tropical medicine centres, and authors of relevant papers for further information about relevant unpublished and ongoing trials. We undertook a separate search for adverse effects of interventions for Old World cutaneous leishmaniasis in September 2015 using MEDLINE. SELECTION CRITERIA: Randomised controlled trials of either single or combination treatments in immunocompetent people with OWCL confirmed by smear, histology, culture, or polymerase chain reaction. The comparators were either no treatment, placebo/vehicle, and/or another active compound. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias and extracted data. We only synthesised data when we were able to identify at least two studies investigating similar treatments and reporting data amenable to pooling. We also recorded data about adverse effects from the corresponding search. MAIN RESULTS: We included 89 studies (of which 40 were new to this update) in 10,583 people with OWCL. The studies included were conducted mainly in the Far or Middle East at regional hospitals, local healthcare clinics, and skin disease research centres. Women accounted for 41.5% of the participants (range: 23% to 80%). The overall mean age of participants was 25 years (range 12 to 56). Most studies lasted between two to six months, with the longest lasting two years; average duration was four months. Most studies were at unclear or high risk for most bias domains. A lack of blinding and reporting bias were present in almost 40% of studies. Two trials were at low risk of bias for all domains. Trials reported the causative species poorly.Here we provide results for the two main comparisons identified: itraconazole (200 mg for six to eight weeks) versus placebo; and paromomycin ointment (15% plus 10% urea, twice daily for 14 days) versus vehicle.In the comparison of oral itraconazole versus placebo, at 2.5 months' follow up, 85/125 participants in the itraconazole group achieved complete cure compared to 54/119 in the placebo group (RR 3.70, 95% CI 0.35 to 38.99; 3 studies; 244 participants). In one study, microbiological or histopathological cure of skin lesions only occurred in the itraconazole group after a mean follow up of 2.5 months (RR 17.00, 95% CI 0.47 to 612.21; 20 participants). However, although the analyses favour oral itraconazole for these outcomes, we cannot be confident in the results due to the very low certainty evidence. More side effects of mild abdominal pain and nausea (RR 2.36, 95% CI 0.74 to 7.47; 3 studies; 204 participants) and mild abnormal liver function (RR 3.08, 95% CI 0.53 to 17.98; 3 studies; 84 participants) occurred in the itraconazole group (as well as reports of headaches and dizziness), compared with the placebo group, but again we rated the certainty of evidence as very low so are unsure of the results.When comparing paromomycin with vehicle, there was no difference in the number of participants who achieved complete cure (RR of 1.00, 95% CI 0.86, 1.17; 383 participants, 2 studies) and microbiological or histopathological cure of skin lesions after a mean follow-up of 2.5 months (RR 1.03, CI 0.88 to 1.20; 383 participants, 2 studies), but the paromomycin group had more skin/local reactions (such as inflammation, vesiculation, pain, redness, or itch) (RR 1.42, 95% CI 0.67 to 3.01; 4 studies; 713 participants). For all of these outcomes, the certainty of evidence was very low, meaning we are unsure about these results.Trial authors did not report the percentage of lesions cured after the end of treatment or speed of healing for either of these key comparisons. AUTHORS' CONCLUSIONS: There was very low-certainty evidence to support the effectiveness of itraconazole and paromomycin ointment for OWCL in terms of cure (i.e. microbiological or histopathological cure and percentage of participants completely cured). Both of these interventions incited more adverse effects, which were mild in nature, than their comparisons, but we could draw no conclusions regarding safety due to the very low certainty of the evidence for this outcome.We downgraded the key outcomes in these two comparisons due to high risk of bias, inconsistency between the results, and imprecision. There is a need for large, well-designed international studies that evaluate long-term effects of current therapies and enable a reliable conclusion about treatments. Future trials should specify the species of leishmaniasis; trials on types caused by Leishmania infantum, L aethiopica, andL donovani are lacking. Research into the effects of treating women of childbearing age, children, people with comorbid conditions, and those who are immunocompromised would also be helpful.It was difficult to evaluate the overall efficacy of any of the numerous treatments due to the variable treatment regimens examined and because RCTs evaluated different Leishmania species and took place in different geographical areas. Some outcomes we looked for but did not find were degree of functional and aesthetic impairment, change in ability to detect Leishmania, quality of life, and emergence of resistance. There were only limited data on prevention of scarring. PMID- 29192425 TI - Understanding the Current Status of Korean Heart Transplantation Based on Initial KOTRY Report.

AB - To evaluate the applicability and clinical applications of Guidelines for Diagnosis and Treatment of Internal Diseases in Traditional Chinese Medicine, so as to provide the basis for the revision of the guidelines. This study was completed by the research and promotion base for traditional Chinese medicine(TCM) standard. The methods of applicability evaluation and application evaluation were used in the study. The questionnaires were filled out to evaluate applicability of the guideline, including doctor's familiarity with the guideline,the quality of the guideline, applicable conditions and clinical applications. The prospective case study analysis method was used to evaluate application of the guideline, including evaluation of clinical application compliance and application results(such as clinical effects, safety and economy). There were two parts in the guideline, which were TCM guideline and Western medicine guideline. The results of applicability evaluation showed that there were no obvious differences between TCM guideline and Western medicine guideline in doctor's familiarity with guideline(85.43%, 84.57%) and the use of the guideline(52.10%, 54.47%); the guidelines with good quality, and higher scores in the scope of application and the use of the term rationality(91.94%, 93.35%); the rationality scores of relevant contents in syndrome differentiation and treatment were more than 75%; the applicable conditions were better, and the safety score was the the highest. The comprehensive applicability evaluation showed that the proportion of the application of TCM guideline and Western medicine guideline were 77.73%, 75.46%, respectively. The results of application evaluation showed that there was high degree coincidence between the guideline with its clinical application; except for "other treatment" and "recuperation and prevention" in TCM, other items got high scores which were more than 90%; in the evaluation of application effects, safety of the guideline was best, economy of the guideline was better, and clincal effect was good.

AB - The aim of this paper was to explore the effects of Frankincense and Myrrh essential oil on transdermal absorption, and investigate the mechanism of permeation on the microstructure and molecular structure of stratum corneum. Through the determination of stratum corneum/medium partition coefficient of ferulicacid in Chuanxiong influenced by Frankincense and Myrrh essential oil, the effects of volatile oil of frankincense and Myrrh on the the microscopic and molecular structure of stratum corneum were explored by observation of skin stratum corneum structure under scanning electron microscopy, and investigation of frankincense and myrrh essential oil effects on the molecular structure of keratin and lipids in stratum corneum under Fourier transform infrared spectroscopy. The results showed that the oil could enhance the distribution of ferulic acid in the stratum corneum and medium, and to a certain extent damaged the imbricate structure of stratum corneum which was originally regularly, neatly, and closely arranged; some epidermal scales turned upward, with local peeling phenomenon. In addition, frankincense and myrrh essential oil caused the relative displacement of CH2 stretching vibration peak of stratum corneum lipids and amide stretching vibration peak of stratum corneum keratin, indicating that frankincense and myrrh essential oil may change the conformation of lipid and keratin in the stratum corneum, increase the bilayer liquidity of the stratum corneum lipid, and change the orderly and compact structure to increase the skin permeability and reduce the effect of barrier function. It can be concluded that Frankincense and Myrrh essential oil can promote the permeation effect by increasing the distribution of drugs in the stratum corneum and changing the structure of the stratum corneum.

The method for evaluating the quality of Paris was established. Infrared spectra of 78 samples from various species in different origins were collected. The contents of polyphyllin I, II and VII were determined by high performance liquid chromatography(HPLC). The HPLC data were combined with the spectral data to predict the contents of three polyphyllin rapidly. Multiplicative signal correction(MSC), standard normal variate(SNV), orthogonal signal correction(OSC), first derivative and second derivative were utilized for the spectral preprocessing. Then, the optimized spectral data were used to establish the quantitative prediction model based on PLSR. The results showed that the best spectral pretreatment of polyphyllin I and II were MSC+OSC+2nd Der and that of polyphyllin VII was MSC+SNV+OSC+2nd Der. In the quantitative calibration model, the determination coefficients (R2) of polyphyllin I, polyphyllin II and polyphyllin VII were 0.930 8, 0.934 8 and 0.912 3, respectively while the Root mean square error of estimation(RMSEE) were 1.855 0, 0.632 3 and 0.001 6 mg*g-1, respectively. In the verification model, the R2 of polyphyllin I, polyphyllin II and polyphyllin VII were 0.948 8, 0.703 6 and 0.801 7, respectively, and the root mean square error of prediction(RMSEP)were 1.704 6, 1.227 8 and 0.002 0 mg*g-1, respectively. Because of the predictive value of quantitative model was closed to the real value, the effect of the model was good. The model of polyphyllin I and II were better than that of polyphyllin VII. The developed method was non-destructive, fast, and accurate. It was feasible to determine the content of polyphyllin in Paris.

AB - Our preliminary study showed that the total flavonoids in Isodon amethystoides(TFIA), a local medicinal herb in Suzhou, had a certain therapeutic effect on adjuvant arthritis, and this therapeutic effect may be achieved through the up-regulation of miR-152 expression. In this paper, the molecular mechanism of TFIA on the pathogenesis of adjuvant arthritis(AA) rats was further studied. AA rats were prepared with complete Freund's adjuvant, and then treated with TFIA by intragastric administration. Real-time qPCR was used to detect the effects of TFIA on the negative regulatory loop of miR-152, methylase DNMT1 and methyl-CpG binding protein MeCP2 in fibroblast like synoviocytes(FLS) of AA rats, as well as the effects of TFIA on the classic Wnt signaling pathway and the expression of fibronectin gene in AA rats. Intragastric administration of TFIA significantly inhibited the expression of DNMT1 and reversed the negative regulatory loop composed of miR-152, DNMT1 and MeCP2 in the pathology of AA rats. After transfection of miR-152 inhibitors into the FLS in treatment group, DNMT1 expression was significantly restored. TFIA significantly up-regulated the expression of SFRP4 and inhibited the expression of beta-catenin, C-myc and ccnd1, the key genes of canonical Wnt signaling pathway. TFIA also significantly inhibited the expression of fibronectin, an AA gene. The effect of TFIA on the expression of SFRP4, beta-catenin, C-myc, ccnd1 and fibronectin was reversed after transfection with miR-152 inhibitors in the treatment group FLS. TFIA may inhibit the DNMT1 expression, up-regulate the SFRP4 expression, inhibit the expression of classical Wnt signaling genes beta-catenin, C-myc, and ccnd1 as well as the RA gene fibronectin expression through the up-regulation of miR-152 expression.

AB - Pinctada fucata oligopeptide is one of key pharmaceutical effective constituents of P. fucata. It is significant to analyze its pharmacological effect and mechanism. This study aims to discover the potential oligopeptides from P. fucata and analyze the mechanism of P. fucata oligopeptide based on in silico technologies and protein interaction network(PIN). First, main protein sequences of P. fucata were collected, and oligopeptides were obtained using in silico gastrointestinal tract proteolysis. Then, key potential targets of P. fucata oligopeptides were obtained through pharmacophore screening. The protein-protein interaction(PPI) of targets was achieved and implemented to construct PIN and analyze the mechanism of P. fucata oligopeptides. P. fucata oligopeptide database was constructed based on in silico technologies, including 458 oligopeptides. Twelve modules were identified from PIN by a graph theoretic clustering algorithm Molecular Complex Detection(MCODE) and analyzed by Gene ontology(GO) enrichment. The results indicated that P. fucata oligopeptides have an effect in treating neurological diseases, such as Alzheimer's disease. In silico proteolysis could be used to analyze the protein sequences of traditional Chinese medicine(TCM). According to the combination of in silico proteolysis and PIN, the biological activity of oligopeptides could be interpreted rapidly based on the known TCM protein sequence. The study provides the methodology basis for rapidly and efficiently implementing the mechanism analysis of TCM oligopeptides.

In nursing, interventions in sexual health are supported with hesitation and those issues constitute a marginal field of nursing research. A narrative literature review was realized in order to establish a portrait of the knowledge produced on this topic in the last decade. This paper illustrates three specific research areas recently developed, namely issues related to sexual autonomy, contextual factors positively or negatively contributing to emotional and sexual life, and the experiences of people identified as having an intellectual disability in this regard. On the basis of these results, different issues related to sexuality and intellectual disability are discussed, including those associated with the negotiation process of affective and sexual life, parenthood as a mediator of emotional and sexual expression, and the inclusiveness issues of sexual diversity in health interventions. Implications for nursing are finally discussed in light of the recent development of its role in sexual health.

In this article, we explore organizational projects led by HN. Depending on the situations, they may concern their health care team or involve institutional hierarchy or other teams. We rely on an intervention study, which enabled us to follow 17 organizational projects led by HN for one year. The results of this study highlight as the main condition for success, the HN' efforts to enable mutual understanding with other interested actors. Managers, who engage their health care team in the development of solutions, bring sustainable results. When problems involve the hierarchy, the managers focus on the development of personal relationships. When problems involve other departments, which they depend on, then they engage themselves into integrative negotiations. These results invite to open discussion about work organization and to formalize organizational projects. This intervention study also points out that work - training at operational audit is relevant for HN. Active par Editorial Manager(r) et ProduXion. PMID- 29192462 TI - ?

Lots of paradoxes question its preservation in favour of general interest and public order against the protection of private interest within an individualistic normative society. Exploring this interrogation, the article's objective is to initiate an ethical discussion from a professional caregiver secrecy's historical and sociological evolution perspective. Thus, with the help of theoretical understandings, especially those by Michel Foucault, medical secrecy is considered a defense of rationality specific to populations' government. This conceptualization finds arguments through social collective norms attached to an alienating biopower at the expense of secrecy integrated as an individualistic and immanent social norm. However, beyond the well-known debate on the absolute necessity for change, evolution... the distance from the Socratic and Hippocratic principles engage people and society in real democratic decisions about Health. Also, health professionals, patients, usgers and society must consider the limits that would lead to medical confidentiality.

They have defined themselves as human beings as opposed to animals and things, on account of characteristics that they regarded as essential. However it now seems necessary to question this perception of humanity and the human condition.Indeed, longer life expectancy together with its related pathologies and medical progress lead us to think differently. Today we realise that those qualities which were thought to belong specifically to human beings, such as awareness, reason, memory and free will, can disappear. Should we conclude then that those whose capacities have decreased or disappeared have become less human or have even lost all human qualities?Such questioning leads to new ways of describing humans whereby they would be defined not in substantial but rather in interpersonal terms.Surely being a person means first and foremost that we live through and for others. And the ethics of care that define men as vulnerable beings, that is to say dependent and needing their fellow human beings' solicitude, would surely offer the possibility of creating a new ?revisited' concept of the person?

This complex double mission includes, among others, the forbidding of cell phones in classroom. OBJECTIVE: this study aims at understanding the involved relational mechanism through the following question: how teachers articulate pedagogical relationship with their required authority at the same time? METHODOLOGY: qualitative study performed between 2015 and 2016 using semi structured interviews interviews of teachers and students of the nursing school. RESULTS: teachers give importance to the quality of relationship, but arrange differently to link authority and training missions. Students accept and recognize this authority as it is part of the internal rules. This legitimacy allows setting up a cooperative pedagogical relation. The internal rules contribute to build up the authority of teachers' team. CONCLUSION: This study opens perspectives for reflection on the notions of relationship, rules, legitimacy and collaboration. Authority is a complex phenomenon which fits, just like pedagogical relation, in a frame providing stability and legitimacy. The internal rules would not standardize the behaviors, but would allow expressing individual liberty.

Nevertheless, the majority succeeded in this training. This positive recovery despite a deleterious context of study questions about this schooling, and on possible resilient mechanisms and tutors of resilience. This research paper in educational sciences will begin with a synthesis of the results of publications about stressors and risk's factors of burnout of these students. We will see how this schooling can be linked to the concept of vulnerability and resilience. Then, we will present the results and the thematic analysis of 30 semi-directive interviews. The objectives of those ones were: to check factors vulnerability of this training, to determine if resilient processes can be observed, and to identify the characteristics of the resilience tutors of these weakened students. After the presentation of the results and of the analysis, we will discuss the links between vulnerability, post-traumatic stress disorder and burnout. We will explain the concept of compassion as one of the predominant characteristics of tutors. Finally, concerning the relational posture of education's professionals, we will show how they could professionally support students' resilience. PMID- 29192467 TI - It's back-to-school time.

AB - BACKGROUND: Natural antioxidants represent an effective option in the prevention and/or improvement of ultraviolet radiations (UVR)-induced/aggravated skin conditions. UVR cause DNA damage in keratinocytes, directly, in the form of cyclobutane pyrimidine dimers (CPDs), or indirectly, through oxidative stress production. Failure of the repair system can result in genetic mutations primarily responsible for the initiation of NMSCs. The aim of our study was to evaluate the in vitro protective effect of milk thistle and olive purified extracts on cultured keratinocytes after solar simulator irradiations (SSR). METHODS: Immortalized keratinocytes were pre-incubated with different concentrations of milk thistle and olive purified extracts, and irradiated with increasing doses of SSR. Thereafter, CPDs and p53 expression were evaluated to assess DNA damage, whereas cellular antioxidants consumption and lipid membranes peroxidation were measured to analyse oxidative stress. RESULTS: The study substances were well tolerated by cells and displayed good cytoprotective and anti-oxidant activities, being milk thistle dry extract more effective in limiting the direct DNA damage, and olive extract particularly able to reduce lipid membrane peroxidation and to increase cellular antioxidants. CONCLUSIONS: Both study substances can be defined as safe compounds, showing differential cytoprotective and anti-oxidant activities and might represent interesting options for NMSCs chemoprevention.

AB - BACKGROUND: Psoriatic arthritis (PsA) is an inflammatory arthritis associated with psoriasis in up to one third of psoriatic patients. Clinically it's characterized from an insidious onset. To help clinicians screen for PsA, several screening tools have been developed. The psoriatic arthritis screening and evaluation questionnaire (PASE) is one of the most used in the Psocare units. The sensibility of PASE is of 83% with a cut off of 47 or greater. The aim of our study is to create an Italian self-administered questionnaire, lighter than the PASE, able to identify patients who need a rheumatologic consultation. METHODS: Between April and June 2016 an Italian group of dermatologists and rheumatologists from north Italy developed a new questionnaire called Screening Tool for Rheumatologic Investigation in Psoriatic Patient (STRIPP). Two hundred and twelve patients with the diagnosis of psoriasis, were screened with STRIPP by dermatologists and all of them sent to the rheumatologist. RESULTS: Forty seven out of 212 patients received the diagnosis of early psoriatic arthritis. Statistical analysis (Spearman Rank correlation test, Mann Whitney test) showed a specificity of 93.3% and a sensibility of 91.5% taking a point of 3.5 as a cut off. CONCLUSIONS: The STRIPP is a very easy questionnaire, quick to out and has a very high sensitivity and specificity, higher than the PASE. Our future goal will be to screen more patients for validating the STRIPP questionnaire. PMID- 29192471 TI - Biologic agents perception in patients attending for the first-time to psoriasis centers: a multicenter Italian survey. AB - BACKGROUND: Inadequate treatment and delayed access to care represent critical issues regarding psoriasis. In Italy, patients treated with biologics are scanty and patients' misinformation could interfere with both biologics prescription and access to care. Literature provide data on disease awareness and perception about biologics in already-treated patients, but there is a lack of information concerning patients never treated with such drugs. METHODS: We conducted a national survey including three academic-based psoriasis care centers at Bologna, Rome and Catania. A questionnaire named Psoriatic Patients's Awareness on Biologics (PPAB) was administered to patients naive for biologics and accessing for the fist-time to a psoriasis care center. RESULTS: Patients from Northern Italy referred to more reliable sources of information and awareness on biologics decreased from North to South. The increase of the Psoriasis Area Severity Index was associated to unawareness about biologics and impaired self-evaluation on the eligibility to treatment. Patients under systemic conventional/multiple therapy were more likely to be unaware about biologics. CONCLUSIONS: Our survey demonstrates that psoriatic patients' awareness is still an unmet need. For more, patients potentially eligible for biologics (severe or treated with systemic conventional/multiple therapy) were less informed. We believe that patients' misinformation could have delayed the access to a psoriasis care center, so that when patients sought help their condition was more severe and required systemic conventional/multiple therapy. Our results reiterate the importance of physicians in the information process and urge the need of a common network among office dermatologists, general practitioners and psoriasis care centers.

AB - Mast cells (MCs) are a potent proangiogenic factor in tumors, they product several pro- angiogenic factors such as fibroblast growth factor 2 (FGF-2), vascular epithelial growth factor (VEGF), tryptase and chymase. Tryptase is a serine protease classified as alpha-tryptase and beta-tryptase, both produced by MCs. Tryptase degrades the tissues, playing an important role in angiogenesis and in the development of metastases. Serum tryptase increases with age, with increased damage to cells and risk of developing a malignancy and it could be considered the expression of a fundamental role of MCs in tumor growth or, on the contrary, in the antitumor response. Many biomarkers have been developed in clinical practice for improving diagnosis and prognosis of some neoplasms. Elevated tryptase levels are found in subgroups of patients with haematologic and solid cancers. In the current review, we want to update the perspectives of tryptase as a potential biomarker in daily practice in different neoplasms. PMID- 29192478 TI - 2015 snapshot of regulated nurses.

AB - The chemical compatibility between electrolytes and electrodes is an extremely important aspect governing the overall impedance of solid-oxide cells. Because these devices work at elevated temperatures, they are especially prone to cation interdiffusion between the cell components, possibly resulting in secondary insulating phases. In this work, we applied X-ray microspectroscopy to study the interface between a samarium-doped ceria (SDC) electrolyte and lanthanum ferrite cathodes (La0.4Sr0.6Fe0.8Cu0.2O3 (LSFCu); La0.9Sr0.1Fe0.85Co0.15O3 (LSCF)), at a submicrometric level. This technique allows to combine the information about the diffusion profiles of cations on the scale of several micrometers, together with the chemical information coming from space-resolved X-ray absorption spectroscopy. In SDC-LSCF bilayers, we find that the prolonged thermal treatments at 1150 degrees C bring about the segregation of samarium and iron in micrometer sized perovskite domains. In both SDC-LSCF and SDC-LSFCu bilayers, cerium diffuses into the cathode perovskite lattice A-site as a reduced Ce3+ cation, whereas La3+ is easily incorporated in the ceria lattice, reaching 30 atom % in the ceria layer in contact with LSFCu.

AB - The emergence of a rich variety of layered materials has attracted considerable attention in recent years because of their exciting properties. However, the applications of layered materials in optoelectronic devices are hampered by the low light absorption of monolayers/few layers, the lack of p-n junction, and the challenges for large-scale production. Here, we report a scalable production of beta-In2Se3/Si heterojunction arrays using pulsed-laser deposition. Photodetectors based on the as-produced heterojunction array are sensitive to a broadband wavelength from ultraviolet (370 nm) to near-infrared (808 nm), showing a high responsivity (5.9 A/W), a decent current on/off ratio (~600), and a superior detectivity (4.9 * 1012 jones), simultaneously. These figures-of-merits are among the best values of the reported heterojunction-based photodetectors. In addition, these devices can further enable the detection of weak signals, as successfully demonstrated with weak light sources including a flashlight, lighter, and fluorescent light. Device physics modeling shows that their high performance is attributed to the strong light absorption of the relatively thick beta-In2Se3 film (20.3 nm) and the rational energy band structures of beta-In2Se3 and Si, which allows efficient separation of photoexcited electron-hole pairs. These results offer a new insight into the rational design of optoelectronic devices from the synergetic effect of layered materials as well as mature semiconductor technology.

AB - The development of versatile strategies toward two-dimensional (2D) porous nanocomposites with tunable pore structures draws immense scientific attention in view of their attractive physiochemical properties and a wide range of promising applications. This paper describes a self-assembly approach for the directed growth of mesoporous polyaniline (PANi) with tunable pore structures and sizes on ultrathin freestanding MoS2 nanosheets in solution, which produces 2D mesoporous PANi/MoS2 nanocomposites. The strategy employs spherical and cylindrical micelles, which are formed by the controlled solution self-assembly of block copolymers, as the soft templates for the construction of well-defined spherical and cylindrical mesopores in the 2D PANi/MoS2 nanocomposites, respectively. With potential applications as supercapacitor electrode materials, the resultant 2D composites show excellent capacitive performance with a maximum capacitance of 500 F g-1 at a current density of 0.5 A g-1, good rate performance, as well as outstanding stability for charge-discharge cycling. Moreover, the 2D mesoporous nanocomposites offer an opportunity for the study on the influence of different pore structures on their capacitive performance, which helps to understand the pore structure-property relationship of 2D porous electrode materials and to achieve their electrochemical performance control.

AB - Availability of potable water is a problem especially in developing countries as their water sources are often contaminated biologically as well as by heavy metals. Electrochemical methods are suitable for field application to monitor heavy metal contents. Noble metal electrodes with large surface areas are the subject of intensive development as they can yield an improved signal-to-noise ratio, enhanced sensitivity, and lower limits of detection (LOD). Here, we present a nanostructured Au microelectrode array subsequently modified by selective electrodeposition in lithographically defined circles within a partially cross-linked gelatin layer. This method increased its surface area by a factor of ~1440 in comparison with an original lithography-based prepared array. The Au surface properties can be tailored by a degree of gelatin layer cross linking. We used this array for an ultrasensitive detection of the As3+ ions content by stripping voltammetry achieving LOD of ~0.0212 parts per billion (signal-to-noise ratio = 3.3), 470* below the content limit recommended by the World Health Organization for potable water. These nanostructured arrays were used to detect ions of other metals such as Cr, Cd, Hg, Cu, and Sb. In combination with a portable electrochemical device, we can envision an ultrasensitive heavy metal detection system for field application to monitor heavy metal contamination.

AB - All-inorganic lead halide perovskite quantum dots (CsPbBr3 QDs) are attracting significant research interests because of their highly efficient light-emitting performance combined with tunable emission wavelength facilely realized by ion exchange. However, blue emission from perovskite QDs with strong quantum confinement is rarely reported and suffers from lower luminescence efficiency. Here we report blue-emitting ultrasmall (~3 nm) CsPbBr3 QDs with photoluminescence (PL) quantum yield as high as 68%. Using time-resolved and steady-state PL spectroscopy, we elucidate the mechanism of the highly efficient PL as recombination of excitons localized in radiative band tail states. Through analyzing the spectral-dependent PL lifetime and the PL line shape, we obtain a large band tail width of ~80 meV and a high density of state of ~1020 cm-3. The relaxation of photocarriers into the radiative tail states suppresses the capture by nonradiative centers. Our results provide solid evidence for the positive role of band tail states in the optical properties of lead halide perovskites, which can be further tailored for high-performance optoelectronic devices.

AB - Engineering heterostructures of transition metal disulfides through low-cost and high-yield methods instead of using conventional deposition techniques still have great challenges. Herein, we present a conveniently operated and low-energy consumption solution-processed strategy for the preparation of heterostructures of MoSe2 nanosheet array on layered MoS2, among which the two-dimensional MoS2 surface is uniformly covered with high-density arrays of vertically aligned MoSe2. The unique compositional and structural features of the MoS2-MoSe2 heterostructures not only provide more exposed active sites for sequent electrochemical process, but also facilitate the ion transfer due to the open porous space within the nanosheet array serving as well-defined ionic reservoirs. As a proof of concept, the MoS2-MoSe2 heterostructures serve as promising bifunctional electrodes for both energy conversions and storages, which exhibit an active and acid-stable activity for catalyzing the hydrogen evolution reaction, high specific capacity of 728 F g-1 at 0.1 A g-1, and excellent durability with a remained capacity as high as 676 mA h g-1 after 200 cycles.

AB - Modern vaccines usually require accompanying adjuvants to increase the immune response to antigens. Aluminum (alum) compounds are the most commonly used adjuvants in human vaccinations for infection diseases. However, alum adjuvants are nondegradable, cause side effects due to the persistence of alum at injection sites, and are rather ineffective for cancer immunotherapy, which requires the Th1 immune response. Recently, we have shown that a plain mesoporous silica (MS) adjuvant can stimulate Th1 anticancer immunity for cancer vaccines. Herein, MS nanospheres doped with Ca, Mg, and Zn (MS-Ca, MS-Mg, and MS-Zn) showed significantly higher degradation rates than pure MS. Moreover, MS-Ca, MS-Mg, and MS-Zn nanospheres stimulated anticancer immune response and increased the CD4+ and CD8+ T cell populations in spleen. The MS-Ca, MS-Mg, and MS-Zn nanospheres with improved biodegradability and excellent ability to induce Th1 anticancer immunity show potential for clinical applications as cancer immunoadjuvants.

Unregulated flame retardants had lower median concentrations of 1.06 (2-ethylhexyl-2,3,4,5-tetrabromobenzoate, EH-TBB), 2.42 (1,2-bis(2,4,6-tribromophenoxy)-ethane, BTBPE), 0.52 (2,4,6-tribromophenyl 2,3 dibromopropyl ether, DPTE), and 4.78 (dechlorane plus) ng/g lw. Although these compounds are often described as recent replacements for PBDEs, they were also present in eggs from the 1980s. BDE-209 was the only compound with a significant increase (+7.2% annual change) between 1986 and 2014, while BB-153 and DPTE decreased significantly (-8.0% and -2.8% annual change, respectively). Dechlorane plus showed a nonsignificant increase.

PMID- 29192495 TI - Novel Surface Molecular Functionalization Route To Enhance Environmental Stability of Tellurium-Containing 2D Layers. AB - Recent studies have shown that tellurium-based two-dimensional (2D) crystals undergo dramatic structural, physical, and chemical changes under ambient conditions, which adversely impact their much desired properties. Here, we introduce a diazonium molecule functionalization-based surface engineering route that greatly enhances their environmental stability without sacrificing their much desired properties. Spectroscopy and microscopy results show that diazonium groups significantly slow down the surface reactions, and consequently, gallium telluride (GaTe), zirconium telluride (ZrTe3), and molybdenum ditelluride (MoTe2) gain strong resistance to surface transformation in air or when immersed under water. Density functional theory calculations show that functionalizing molecules reduce surface reactivity of Te-containing 2D surfaces by chemical binding followed by an electron withdrawal process. While pristine surfaces structurally decompose because of strong reactivity of Te surface atoms, passivated functionalized surfaces retain their structural anisotropy, optical band gap, and emission characteristics as evidenced by our conductive atomic force microscopy, photoluminescence, and absorption spectroscopy measurements. Overall, our findings offer an effective method to increase the stability of these environmentally sensitive materials without impacting much of their physical properties.

AB - Hybrid lead halide spin coated perovskite films have been successfully tested as portable, flexible, operated at room temperature, self-powered, and ultrasensitive ozone sensing elements. The electrical resistance of the hybrid lead mixed halide perovskite (CH3NH3PbI3-xClx) sensing element, was immediately decreased when exposed to an ozone (O3) environment and manage to recover its pristine electrical conductivity values within few seconds after the complete removal of ozone gas. The sensing measurements showed different response times at different gas concentrations, good repeatability, ultrahigh sensitivity and fast recovery time. To the best of our knowledge, this is the first time that a lead halide perovskite semiconductor material is demonstrating its sensing properties in an ozone environment. This work shows the potential of hybrid lead halide based perovskites as reliable sensing elements, serving the objectives of environmental control, with important socioeconomic impact. PMID- 29192497 TI - Identification of New Anti-inflammatory Peptides from Zein Hydrolysate after Simulated Gastrointestinal Digestion and Transport in Caco-2 Cells. AB - Chronic inflammation is an underlying contributor to various chronic diseases. The objectives of this study were to investigate the anti-inflammatory activity of zein hydrolysate after simulated gastrointestinal digestion and Caco-2 cell absorption and to identify novel anti-inflammatory peptides after transport across Caco-2 cells. Three zein hydrolysates were prepared and further digested using gastrointestinal proteases; their transports were studied in Caco-2 cells. Anti-inflammatory activity was studied in endothelial EA.hy926 cells. Three zein hydrolysates and their digests significantly decreased the expression of tumor necrosis factor-alpha (TNF-alpha) induced pro-inflammatory vascular cell adhesion molecule-1 (VCAM-1) by 37.3-66.0%. Eleven novel peptides with 5-9 amino acid residues were sequenced; three peptides showed strong anti-inflammatory activity by inhibiting the VCAM-1 by 54-38.9% and intercellular cell adhesion molecule-1 (ICAM-1) by 36.5-28.6% at 0.2 mM. A new approach to identify novel anti inflammatory peptides that could survive gastrointestinal digestion and absorption was developed.

PMID- 29192498 TI - Membrane Protein Structure in Live Cells: Methodology for Studying Drug Interaction by Mass Spectrometry-Based Footprinting. AB - Mass spectrometry-based footprinting is an emerging approach for studying protein structure. Because integral membrane proteins are difficult targets for conventional structural biology, we recently developed a mass spectrometry (MS) footprinting method to probe membrane protein-drug interactions in live cells. This method can detect structural differences between apo and drug-bound states of membrane proteins, with the changes inferred from MS quantification of the cysteine modification pattern, generated by residue-specific chemical labeling. Here, we describe the experimental design, interpretation, advantages, and limitations of using cysteine footprinting by taking as an example the interaction of warfarin with vitamin K epoxide reductase, a human membrane protein. Compared with other structural methods, footprinting of proteins in live cells produces structural information for the near native state. Knowledge of cellular conformational states is a necessary complement to the high-resolution structures obtained from purified proteins in vitro. Thus, the MS footprinting method is broadly applicable in membrane protein biology. Future directions include probing flexible motions of membrane proteins and their interaction interface in live cells, which are often beyond the reach of conventional structural methods. PMID- 29192500 TI - Comparative Proteomics of Contrasting Maize Genotypes Provides Insights into Salt Stress Tolerance Mechanisms. AB - Salt stress is a major abiotic factor limiting maize yield. To characterize the mechanism underlying maize salt tolerance, we compared the seedling root proteomes of salt-tolerant Jing724 and salt-sensitive D9H. The germination rate and growth parameter values (weight and length) were higher for Jing724 than for D9H under saline conditions. Using an iTRAQ-based method, we identified 513 differentially regulated proteins (DRPs), with 83 and 386 DRPs specific to Jing724 and D9H, respectively. In salt-stressed Jing724, the DRPs were primarily associated with the pentose phosphate pathway, glutathione metabolism, and nitrogen metabolism. Key DRPs, such as glucose-6-phosphate 1-dehydrogenase, NADPH producing dehydrogenase, glutamate synthase, and glutamine synthetase, were identified based on pathway enrichment and protein-protein interaction analyses. Moreover, salt-responsive proteins in Jing724 seedlings were implicated in energy management, maintenance of redox homeostasis, detoxification of ammonia, regulation of osmotic homeostasis, stress defense and adaptation, biotic cross tolerance, and regulation of gene expression. Quantitative analyses of superoxide dismutase activity, malondialdehyde content, relative electrolyte leakage, and proline content were consistent with the predicted changes based on DRP functions. Furthermore, changes in the abundance of eight representative DRPs were correlated with the corresponding mRNA levels. Our results may be useful for elucidating the molecular networks mediating salt tolerance. PMID- 29192501 TI - All Organic Label-like Copper(II) Ions Fluorescent Film Sensors with High Sensitivity and Stretchability. AB - Deep learning and analysis of heavy metal concentration are very crucial to our life, for it plays an essential role in both environmental and human health. In this paper, we developed a new Cu (II) ions sensor made by all organic material with bending and stretching properties. The new sensor consists of chlorophyll-a extracted from fresh leaves of Common Garcinia, plant fiber and with the use of PDMS as a substrate. Fluorescence spectra study shows that chlorophyll-a is significantly much more sensitive to Cu (II) ions than any other heavy metal ions and the device sensitivity outperforms all the Cu (II) ions sensors ever reported. The result fully shows the selectivity of chlorophyll-a toward Cu (II) ions. Bending and stretching tests show that the sensor has an outstanding durability, which can be used to develop accompanying applications, such as real time sampling and the analysis of Cu (II) concentration specified in athlete's sweat or patients with brain death and Parkinson's disease. PMID- 29192502 TI - Ferrous Iron Oxidation under Varying pO2 Levels: The Effect of Fe(III)/Al(III) Oxide Minerals and Organic Matter. AB - Abiotic Fe(II) oxidation by O2 commonly occurs in the presence of mineral sorbents and organic matter (OM) in soils and sediments; however, this tertiary system has rarely been studied. Therefore, we examined the impacts of mineral surfaces (goethite and gamma-Al2O3) and organic matter [Suwannee River fulvic acid (SRFA)] on Fe(II) oxidation rates and the resulting Fe(III) (oxyhydr)oxides under 21 and 1% pO2 at pH 6. We tracked Fe dynamics by adding 57Fe(II) to 56Fe labeled goethite and gamma-Al2O3 and characterized the resulting solids using 57Fe Mossbauer spectroscopy. We found Fe(II) oxidation was slower at low pO2 and resulted in higher-crystallinity Fe(III) phases. Relative to oxidation of Fe(II)(aq) alone, both goethite and gamma-Al2O3 surfaces increased Fe(II) oxidation rates regardless of pO2 levels, with goethite being the stronger catalyst. Goethite surfaces promoted the formation of crystalline goethite, while gamma-Al2O3 favored nano/small particle or disordered goethite and some lepidocrocite; oxidation of Fe(II)aq alone favored lepidocrocite. SRFA reduced oxidation rates in all treatments except the mineral-free systems at 21% pO2, and SRFA decreased Fe(III) phase crystallinity, facilitating low-crystalline ferrihydrite in the absence of mineral sorbents, low-crystalline lepidocrocite in the presence of gamma-Al2O3, but either crystalline goethite or ferrihydrite when goethite was present. This work highlights that the oxidation rate, the types of mineral surfaces, and OM control Fe(III) precipitate composition. PMID- 29192503 TI - Dynamics of Nanoparticles in Entangled Polymer Solutions. AB - The mean square displacement ?r2? of nanoparticle probes dispersed in simple isotropic liquids and in polymer solutions is interrogated using fluorescence correlation spectroscopy and single-particle tracking (SPT) experiments. Probe dynamics in different regimes of particle diameter (d), relative to characteristic polymer length scales, including the correlation length (xi), the entanglement mesh size (a), and the radius of gyration (Rg), are investigated. In simple fluids and for polymer solutions in which d ? Rg, long-time particle dynamics obey random-walk statistics ?r2?:t, with the bulk zero-shear viscosity of the polymer solution determining the frictional resistance to particle motion. In contrast, in polymer solutions with d < Rg, polymer molecules in solution exert noncontinuum resistances to particle motion and nanoparticle probes appear to interact hydrodynamically only with a local fluid medium with effective drag comparable to that of a solution of polymer chain segments with sizes similar to those of the nanoparticle probes. Under these conditions, the nanoparticles exhibit orders of magnitude faster dynamics than those expected from continuum predictions based on the Stokes-Einstein relation. SPT measurements further show that when d > a, nanoparticle dynamics transition from diffusive to subdiffusive on long timescales, reminiscent of particle transport in a field with obstructions. This last finding is in stark contrast to the nanoparticle dynamics observed in entangled polymer melts, where X-ray photon correlation spectroscopy measurements reveal faster but hyperdiffusive dynamics. We analyze these results with the help of the hopping model for particle dynamics in polymers proposed by Cai et al. and, on that basis, discuss the physical origins of the local drag experienced by the nanoparticles in entangled polymer solutions. PMID- 29192504 TI - Utility of Fecal Calprotectin in Evaluation of Chronic Gastrointestinal Symptoms in Primary Care. AB - Fecal calprotectin (FC) is a marker of intestinal inflammation. Data are limited on utility of routine FC testing in pediatric primary care. Participants 0 to 18 years old who had an FC test in the years 2010-2014 were retrospectively identified. Those with less than a year of follow-up or a prior diagnosis of inflammatory bowel disease (IBD) were excluded. In all, 84% (689/822) had normal FC; no participant with normal FC was diagnosed with IBD in the subsequent 12 months. Also, 16% (133/822) had elevated FC, and 31% of those (42/133) were diagnosed with IBD. FC values for IBD and non-IBD groups were 1084 ug/g (interquartile range [IQR] = 514.4-2000) and 27.05 ug/g (IQR = 15.6-62.6; P < .001), respectively. Abdominal pain was the primary indication. In this cohort, sensitivity of FC for IBD is 100%, and specificity is 88%. The FC test can be an excellent tool in the primary care setting to exclude IBD and avoid unnecessary referrals and colonoscopies. PMID- 29192505 TI - US oncology-wide incidence, duration, costs and deaths from chemoradiation mucositis and antimucositis therapy benefits. AB - Approximate oncology-wide incidence, duration, costs and deaths associated with mucositis and identify health economic benefits of antimucositis therapies. Review the literature relevant to the clinical experience of mucositis by pathophysiology, incidence, duration, costs and deaths. Use US insurance actuarial and epidemiology on cancer to generalize an oncology-wide impact of toxic mucositis. Toxic mucositis causes oropharyngoesophageal ulcerations, chemo induced nausea, vomiting and diarrhea. Acutely, it lasts 102 days/six cycles of chemotherapy, 60 days in human stem-cell transplantation patients and 70-84 days in head and neck cancer patients at annual costs of US$13.23 billion/522,166 treated patients (US$20,892/erosive-type mucositis patient, US$25,337/physiologic mucositis patient) and 46,699 deaths. Using antimucositis therapies prior to 2013 provided fractional benefits at high costs. By completely preventing and rapidly reversing mucositis, high-potency polymerized cross-linked sucralfate promises superior health economic benefits. PMID- 29192506 TI - Extensive Hand Thermal and Blast Injury From Electronic Cigarette Explosion: A Case Report. AB - BACKGROUND: As the use of electronic cigarettes rises, more reports of injuries related to device explosion are surfacing. METHODS: Presented here is the case of a 35-year-old man sustaining extensive thermal and blast injuries to his hand when the device exploded while he was holding it. He required multiple surgeries involving groin flap coverage, tendon transfer, and nerve grafting to optimize his postinjury function. RESULTS: While much of his hand function has been restored, he has continued deficits in range of motion and sensation as a result of the incident. CONCLUSIONS: With increasing numbers of such injuries, hand surgeons must be aware of the blast mechanism involved so as to avoid missing deep soft tissue injury or disruption of deep structures, as demonstrated in this case. PMID- 29192507 TI - Effect of Transcranial Direct Current Stimulation in Patients With Tinnitus: A Meta-Analysis and Systematic Review. AB - OBJECTIVES: Subjective tinnitus is a phantom sensation experienced without any external source of sound that profoundly impacts the quality of life. Some investigations have claimed that transcranial direct current stimulation (tDCS) reduces tinnitus, but studies on tDCS have demonstrated variable results. This meta-analysis aimed to examine the effect of tDCS on patients with tinnitus. METHODS: We searched for articles published through January 5, 2016, in Medline, Cochrane, EMBASE, and Google Scholar using the following keywords: tinnitus, transcranial direct current stimulation, and tDCS. The study outcomes were change in magnitude estimates of loudness (loudness), tinnitus-related distress (distress), and Tinnitus Handicap Inventory (THI). RESULTS: Pooled results demonstrated that tDCS did not have a beneficial effect on loudness (pooled standardized difference in means = 0.674, 95% CI, -0.089 to 1.437, P = .083). Further, the pooled results demonstrated a greater reduction in distress for the tDCS group (pooled standardized difference in means = 0.634, 95% CI, 0.021-1.247, P = .043). CONCLUSIONS: We conclude that the pooled results demonstrated a greater reduction in distress for groups treated with tDCS as compared with those administered a sham treatment. PMID- 29192508 TI - Screening for Depression and Psychological Distress in a Currently Serving Military Population: The Diagnostic Accuracy of the K10 and the PHQ9. AB - This study is the first to examine the diagnostic accuracy of two depression screening scales-the Kessler Psychological Distress Scale (K10) and the Patient Health Questionnaire (PHQ)-in an entire regular-serving military population. Currently serving Australian Defence Force personnel ( n = 24,481) completed the K10 and PHQ9. Then a targeted subsample (i.e., the analysis sample, n = 1,730) completed a diagnostic interview to identify DSM-IV 30-day disorder. Weighted results represented the entire population ( N = 50,049). Both scales similarly showed a good ability to discriminate between personnel with and without depressive disorders. Optimal cutoffs (19 for K10, 6 for PHQ9) showed high sensitivity and good specificity, and were similar to though slightly lower than those recommended in civilian populations. Both scales appear to be valid screens for depressive disorder in the military, using the cutoffs identified. As both performed similarly, scale choice may depend on other factors (e.g., availability of norms). PMID- 29192509 TI - A Comparison of Removal Rates of Headless Screws Versus Headed Screws in Calcaneal Osteotomy. AB - BACKGROUND: Calcaneal osteotomy has been used to successfully treat both valgus and varus hindfoot deformities. Pain associated with implanted hardware may lead to further surgical intervention for hardware removal. Headless screws have been used to reduce postoperative hardware-associated pain and accompanying hardware removal, but data proving their effectiveness in this regard is lacking. The purpose of this study is to compare the rates of removal of headed and headless screws utilized in calcaneal osteotomy. METHODS: We conducted a retrospective chart review of 74 patients who underwent calcaneal osteotomy between January 2010 and December 2014. The cohort was divided into 2 groups by fixation method: a headed screw and a headless screw group. Bivariate associations between infection or hardware removal, and screw type, screw head width, gender, smoking status, alcohol, hypertension, diabetes, hyperlipidemia, age, and body mass index were assessed using t-tests and Fisher's exact/chi2 tests for continuous and discrete variables, respectively. RESULTS: Headed screws were removed more frequently than headless screws (P < .0001): 15 of 30 (50%) feet that received headed screws and 4 of 44 (9%) of feet that received headless screws underwent subsequent revision for screw removal. In all cases, screws were removed because of pain. The calcaneal union rate was 100% in both cohorts. CONCLUSION: The rate of screw removal in calcaneal osteotomies is significantly lower in patients who receive headless screws than in those receiving headed screws. LEVELS OF EVIDENCE: Level IV. PMID- 29192510 TI - Aflatoxin B1 detoxification by cell-free extracts of Rhodococcus strains. AB - Aflatoxin B1 (AFB1) produced by Aspergillus molds is a genotoxic and carcinogenic mycotoxin. For the elimination of mycotoxins from food and feed, biodetoxification can be a successful tool. The aim of this study was to reveal biodetoxification with the cell-free extracts of Rhodococcus erythropolis NI1 and Rhodococcus rhodochrous NI2, which have been already proved to detoxify AFB1. Extracellular matrices of cultures and also intracellular extracts were applied for detoxification. In both cases, media containing constitutively produced and AFB1-induced enzymes were tested, respectively. The pH tolerance of enzymes in the detoxification was examined at pH 7, 7.5, and 8. The remained genotoxicity was detected by SOS-Chromotest and the AFB1 concentration was measured by high performance liquid chromatography with fluorescence detection. In the extracellular matrix, no reduction of genotoxicity was observed. However, detoxification was completed by intracellular enzymes. In intracellular extracts of both strains, genotoxicity was ceased by the constitutive enzymes within 6 h but induced and constitutive enzymes collectively achieved this result within minutes. Moreover, total biodetoxification was observed at every pH adjustment. Analytical results confirmed >84% degradation potential in each sample. Our results indicate a uniquely fast way for the detoxification of AFB1 with intracellular enzymes of R. erythropolis NI1 and R. rhodochrous NI2. PMID- 29192511 TI - The Kinect Project: Group motion-based gaming for people living with dementia. AB - Engaging in enjoyable activities is an essential part of well-being, but people with dementia can find participation increasingly difficult. Motion-based technologies can provide meaningful engagement in a wide range of activities, but for people with dementia to take advantage of these devices requires a good understanding of how best to select and present these activities to this population. The objective of this study was to explore the use of motion-based technology (Xbox Kinect) as a group activity for people with dementia who attend adult day programmes. This qualitative study took place in an adult day programme for older adults with age-related challenges. Participants (n = 23) were observed while playing a digital bowling game presented on Xbox Kinect one hour per week for a period of 20 weeks, to capture naturalistic data. Field notes generated through observations were transcribed and analysed to identify emerging themes. The findings revealed three predominant themes which illustrate the potential of motion-based technology as a group activity for people with dementia who attend adult day programmes: (a) the importance of having a trained trainer, (b) learning versus mastery and (c) playing 'independently together'. People with dementia can learn to play games presented on motion-based technology and enjoy doing so. Furthermore, using the technology in a group setting fostered an encouraging and supportive environment which further contributed to the leisure experience. However, to be used most effectively, staff must be trained to set-up and interact with the technology, as well as introduce, teach and support people with dementia to use it. PMID- 29192512 TI - Assessing apathy in long-term care residents with dementia: Who should be the rater? AB - Background Apathy is prominent in persons with dementia and apathy assessment is challenging. It remains unclear who should conduct apathy assessments in long term care settings for residents with moderate to advanced dementia. The Apathy Evaluation Scale (AES) is a widely used instrument and its use for long-term care residents with dementia needs to be further established. This study explored the relationship among apathy assessments conducted by family and clinical caregivers using the original AES (AES-18) and the nursing home version (AES-10). Methods This study used a cross-sectional, descriptive design and enrolled 15 quartets of participants recruited from long-term care settings. Each quartet consisted of one resident with dementia, one family member, one certified nursing assistant, and one licensed practical nurse or activity staff. Family, certified nursing assistants, and licensed practical nurses/activity staff rated the resident's apathy level on the AES independently. Bivariate Pearson correlation coefficients were used for analysis. Results The results revealed that ratings conducted by certified nursing assistants and licensed practical nurses/activity staff were moderately correlated for the AES-18 and the result approached statistical significance (r = 0.47, p = .08). None of the other AES ratings among family, certified nursing assistants, and licensed practical nurses/activity staff were significantly correlated. Discussion Family and clinical caregivers were incongruent on their AES ratings of apathy. It remains undetermined which rater provides the most valid AES rating for residents with dementia. Findings from this study further highlight challenges in rating apathy in this population. Future research is needed to determine best practices for accurate apathy assessment for residents with dementia in long-term care. PMID- 29192513 TI - Medication and care in Alzheimer's patients in the acute care setting: A qualitative analysis. AB - The acute hospital admission of patients with dementia is associated with poor outcome and higher costs. Much of our knowledge on how hospital stays are experienced by patients and staff is generated from short and fragmented data collections, in which the significance of knowledge about day-to-day care might be overlooked, and might partly explain why the poor outcome for this group of patients is not fully understood. This study used participant observation to follow patients with Alzheimer's disease admitted to orthopaedic wards after fall incidents. To gather longitudinal data, patients were followed during day and evening shifts, from admission to discharge. The data were interpreted from a phenomenological-hermeneutic perspective, inspired by Ricoeur's interpretation theory. The data showed that, despite having little specific knowledge about dementia care, staff were able to gather information about the patient's needs and wishes relevant to administrating medicine in a person-centred way. However, much of this valuable information was lost between shifts or became hidden among the overwhelming amount of information in electronic patient records. As a consequence, much of the knowledge about individual patients' needs and wishes had to be collected all over again at every shift. The study concludes that careful handover of information on person-centred dementia care can play an important role in making hospital stays more dementia-friendly. PMID- 29192514 TI - Iranian relatives' attitudes towards culturally profiled nursing homes for individuals living with dementia. AB - This article discusses Iranian family members' attitudes towards the culturally profiled nursing home, their relationships with the staff, the obstacles, their hopes and their fears. This study is based on qualitative research using 29 semi structured interviews with family members who had previously been informal caregivers, as well as using fieldwork, all in the same nursing home. The interviews were analysed by the three steps of content analysis. The results show the identification of three main categories with nine main subcategories. The categories and subcategories in the table clarify and explain how the interviewees tended to compare the situation in Iran with that in Sweden, how they perceived the situation in Sweden and finally how they also saw the culturally profiled nursing home.

PMID- 29192516 TI - Knockdown of angiopoietin-like 2 mimics the benefits of intermittent fasting on insulin responsiveness and weight loss. AB - Angiopoietin-like 2 (ANGPTL2) is an inflammatory adipokine linking obesity to insulin resistance. Intermittent fasting, on the other hand, is a lifestyle intervention able to prevent obesity and diabetes but difficult to implement and maintain. Our objectives were to characterize a link between ANGPTL2 and intermittent fasting and to investigate whether the knockdown of ANGPTL2 reproduces the benefits of intermittent fasting on weight gain and insulin responsiveness in knockdown and wild-type littermates mice. Intermittent fasting, access to food ad libitum once every other day, was initiated at the age of three months and maintained for four months. Intermittent fasting decreased by 63% (p < 0.05) gene expression of angptl2 in adipose tissue of wild-type mice. As expected, intermittent fasting improved insulin sensitivity (p < 0.05) and limited weight gain (p < 0.05) in wild-type mice. Knockdown mice fed ad libitum, however, were comparable to wild-type mice following the intermittent fasting regimen: insulin sensitivity and weight gain were identical, while intermittent fasting had no additional impact on these parameters in knockdown mice. Energy intake was similar between both wild-type fed intermittent fasting and ANGPTL2 knockdown mice fed ad libitum, suggesting that intermittent fasting and knockdown of ANGPTL2 equally lower feeding efficiency. These results suggest that the reduction of ANGPTL2 could be a useful and promising strategy to prevent obesity and insulin resistance, although further investigation of the mechanisms linking ANGPTL2 and intermittent fasting is warranted. Impact statement Intermittent fasting is an efficient diet pattern to prevent weight gain and improve insulin sensitivity. It is, however, a difficult regimen to follow and compliance is expected to be very low. In this work, we demonstrate that knockdown of ANGPTL2 in mice fed ad libitum mimics the beneficial effects of intermittent fasting on weight gain and insulin sensitivity in wild-type mice. ANGPTL2 is a cytokine positively associated with fat mass in humans, which inactivation in mice improves resistance to a high-fat metabolic challenge. This study provides a novel pathway by which IF acts to limit obesity despite equivalent energy intake. The development of a pharmacological ANGPTL2 antagonist could provide an efficient tool to reduce the burden of obesity. PMID- 29192517 TI - Applying the methodology of Design of Experiments to stability studies: a Partial Least Squares approach for evaluation of drug stability. AB - The aim of the present research is to show that the methodology of Design of Experiments can be applied to stability data evaluation, as they can be seen as multi-factor and multi-level experimental designs. Linear regression analysis is usually an approach for analyzing stability data, but multivariate statistical methods could also be used to assess drug stability during the development phase. Data from a stability study for a pharmaceutical product with hydrochlorothiazide (HCTZ) as an unstable drug substance was used as a case example in this paper. The design space of the stability study was modeled using Umetrics MODDE 10.1 software. We showed that a Partial Least Squares model could be used for a multi dimensional presentation of all data generated in a stability study and for determination of the relationship among factors that influence drug stability. It might also be used for stability predictions and potentially for the optimization of the extent of stability testing needed to determine shelf life and storage conditions, which would be time and cost-effective for the pharmaceutical industry. PMID- 29192518 TI - In vitro dissolution method fitted to in vivo absorption profile of rivaroxaban immediate-release tablets applying in silico data. AB - OBJECTIVE: This study aimed to develop and validate an in vitro dissolution method based on in silico-in vivo data to determine whether an in vitro-in vivo relationship could be established for rivaroxaban in immediate-release tablets. SIGNIFICANCE: Oral drugs with high permeability but poorly soluble in aqueous media, such as the anticoagulant rivaroxaban, have a major potential to reach a high level of in vitro-in vivo relationship. Currently, there is no study on scientific literature approaching the development of RIV dissolution profile based on its in vivo performance. METHODS AND RESULTS: Drug plasma concentration values were modeled using computer simulation with adjustment of pharmacokinetic properties. Those values were converted into drug fractions absorbed by the Wagner-Nelson deconvolution approach. Gradual and continuous dissolution of RIV tablets was obtained with a 30 rpm basket on 50 mM sodium acetate +0.2% SDS, pH 6.5 medium. Dissolution was conducted for up to 180 min. The fraction absorbed was plotted against the drug fraction dissolved, and a linear point-to-point regression (R2 = 0.9961) obtained. CONCLUSION: The in vitro dissolution method designed promoted a more convenient dissolution profile of RIV tablets, whereas it suggests a better relationship with in vivo performance.

AB - OBJECTIVES: The aim of this study is to derive a consensus on an interdisciplinary competency framework regarding a holistic approach for audiological rehabilitation (AR), which includes disciplines from medicine, engineering, social sciences and humanities. DESIGN: We employed a modified Delphi method. In the first round survey, experts were asked to rate an initial list of 28 generic interdisciplinary competencies and to propose specific knowledge areas for AR. In the second round, experts were asked to reconsider their answers in light of the group answers of the first round. STUDY SAMPLE: An international panel of 27 experts from different disciplines in AR completed the first round. Twenty-two of them completed the second round. RESULTS: We developed a competency framework consisting of 21 generic interdisciplinary competencies grouped in five domains and nine specific competencies (knowledge areas) in three clusters. Suggestions for the implementation of the generic competencies in interdisciplinary programmes were identified. CONCLUSIONS: This study reveals insights into the interdisciplinary competencies that are unique for AR. The framework will be useful for educators in developing interdisciplinary programmes as well as for professionals in considering their lifelong training needs in AR.

AB - INTRODUCTION: Hormone receptor positive (HR+) breast cancer represents the most common subtype of breast cancer. Metastatic HR+ breast cancer may develop resistance to standard hormone therapies, arising from genomic alterations in the estrogen receptor and/or upregulation of other signal transduction pathways. Areas covered: In this review, we discuss hormone resistance and strategies to overcome it, from the pre-clinical and clinical perspectives. This review includes a discussion of inhibition of the PI3K/AKT/mTOR, CDK 4/6, histone deacetylation, fibroblast growth factor receptor, and immune pathways, based on review of relevant literature. Expert commentary: Several emerging novel therapies to improve the response to hormone therapy are approved or are in development. The most promising agents at present are inhibitors of CDK 4/6 and mTOR, which have already been incorporated into treatment in the advanced stage setting and are under study for early stage disease. PMID- 29192521 TI - High efficiency dry coating of non-subcoated pellets for sustained drug release formulations using amino methacrylate copolymers. AB - Dry coating utilizing a fluidized bed was evaluated in order to produce films with sustained drug release using amino methacrylate copolymers as film former. In contrast to other dry coating procedures using amino methacrylate copolymers, the described method enables an appropriate polymer adhesion by the selection of a plasticizer additive mixture in combination with the use of a three-way nozzle for simultaneous application. Well spreading fatty acid esters were found to increase the coating efficiency from 73% to approximately 86%, when they were used in conjunction with the plasticizer. Pellets were used as drug cores without previous treatment. After a curing step at 55 degrees C, the pellets exhibited a prolongation of the drug release over a period of about 6 h. Mainly the three parameters, coating level, composition of the polymers in the coating mixture, and the type of plasticizer, were found to exert distinct influence on the dissolution profile. Despite the differences in the coating procedure, the dissolution profiles of the coated pellets as well as the influencing parameters were similar to those known from conventional coating techniques. PMID- 29192522 TI - Chemical partitioning of fine particle-bound As, Cd, Cr, Ni, Co, Pb and assessment of associated cancer risk due to inhalation, ingestion and dermal exposure. AB - The bioavailability and human health risks of As, Pb, Ni, Co, Cr and Cd in fine particulate matter (PM2.5) at an urban site on a National highway in Agra, India were investigated. Inductively coupled plasma-optical emission spectrometer was used for metal analysis in sequentially extracted samples to ascertain the highly mobile, reducible, bioavailable and immobile fractions of the metals. Cancer risk resulting from inhalation, dermal and ingestion exposure to each metal in these fractions was calculated according to US EPA models. The average mass concentration of PM2.5 was 87.16 +/- 62.51 MUg/m3. Cr, Ni and Pb were the most abundant metals. The results showed that Pb and Cr were higher in the mobile fraction. Cd and Co had high bioavailability. Ingestion is the major exposure pathway for all heavy metals except Cr to infants, children and adults followed by inhalation and dermal contact. The cumulative risk for Cr(VI) due to dermal and inhalation routes exceed the maximum acceptable limit for children of age 1-7 years, 8-15 years and adults when total concentration is considered, but the estimated risks are within the acceptable limit when the bioavailable, water soluble and mobile fraction are taken into account. Hence the study shows that children and adults living in the vicinity of this site are more susceptible, hence more attention should be paid to protect them from pollution hazards. The study indicates the importance of metal speciation in assessing associated human health risks. PMID- 29192523 TI - Suicide clusters among young Kenyan men. AB - Suicide is a leading cause of global mortality. Suicide clusters have recently been identified among peer networks in high-income countries. This study investigates dynamics of suicide clustering within social networks of young Kenya men ( n = 532; 18-34 years). We found a strong, statistically significant association between reported number of friends who previously attempted suicide and present suicide ideation (odds ratio = 1.9; 95% confidence interval (1.42, 2.54); p < 0.001). This association was mediated by lower collective self-esteem (23% of total effect). Meaning in life further mediated the association between collective self-esteem and suicide ideation. Survivors of peer suicide should be evaluated for suicide risk. PMID- 29192524 TI - Problematic gaming behaviour and health-related outcomes: A systematic review and meta-analysis. AB - This systematic review and meta-analysis aimed to investigate the interplay between problematic gaming behaviour and health-related outcomes at different developmental stages. A total of 50 empirical studies met the specified inclusion criteria, and a meta-analysis using correlation coefficients was used for the studies that reported adverse health implications regarding the impact of problematic gaming behaviour on depression, anxiety, obsessive-compulsive disorder and somatisation. Overall, the results suggested that problematic gaming behaviour is significantly associated with a wide range of detrimental health related outcomes. Finally, the limitations of this review alongside its implications were discussed and considered for future research. PMID- 29192525 TI - Caring for musicians' ears: insights from audiologists and manufacturers reveal need for evidence-based guidelines. AB - OBJECTIVE: This study investigated clinical care delivered to musicians in Australia by audiologists and manufacturers of musicians' hearing protectors (MHP). DESIGN: Audiologists with experience treating musicians were invited to complete a survey on their service delivery. A second survey was administered to manufacturers of MHPs. STUDY SAMPLE: Four manufacturers of MHP and 31 audiologists completed the surveys. Post hoc analyses were performed comparing the responses of audiologists with more versus less clinical experience; and those with and without musical training. RESULTS: There was considerable variation in the audiological care provided to musicians. Only one-third of audiologists performed pure-tone audiometry prior to MHP fitting, and there was little consistency across the sample in relation to impression taking, preferred attenuation or selection of canal length. There was also significant variation in the manufacturers' approach to MHP, each of whom provided different recommendations regarding preferred impression techniques and material viscosity. CONCLUSIONS: The results of this study reveal lack of consistency across the hearing healthcare sector with respect to care of musicians' hearing, with potential to impact upon the satisfaction with, and usage of, MHP. There is need for evidence-based, best practice guidelines and training to support clinical audiologists in providing optimal care. PMID- 29192526 TI - Intelligence Assessment Instruments in Adult Prison Populations: A Systematic Review. AB - Detection of intellectual disability (ID) in the penitentiary system is important for the following reasons: (a) to provide assistance to people with ID in understanding their legal rights and court proceedings; (b) to facilitate rehabilitation programs tailored to ID patients, which improves the enhancement of their quality of life and reduces their risk of reoffending; and (c) to provide a reliable estimate of the risk of offence recidivism. It requires a short assessment instrument that provides a reliable estimation of a person's intellectual functioning at the earliest possible stage of this process. The aim of this systematic review is (a) to provide an overview of recent short assessment instruments that provide a full-scale IQ score in adult prison populations and (b) to achieve a quality measurement of the validation studies regarding these instruments to determine which tests are most feasible in this target population. The Preferred Reporting Items for Systematic reviews and Meta Analyses Statement is used to ensure reliability. The Satz-Mogel, an item reduction short form of the Wechsler Adult Intelligence Scale, shows the highest correlation with the golden standard and is described to be most reliable. Nevertheless, when it comes to applicability in prison populations, the shorter and less verbal Quick Test can be preferred over others. Without affecting these conclusions, major limitations emerge from the present systematic review, which give rise to several important recommendations for further research.

PMID- 29192528 TI - Hospitalization costs and resource allocation in cholecystectomy with use of intravenous versus oral acetaminophen. AB - OBJECTIVE: To evaluate intravenous (IV) acetaminophen (APAP) vs oral APAP use as adjunctive analgesics in cholecystectomy patients by comparing associated hospital length of stay (LOS), hospital costs, opioid use, and rates of nausea/vomiting, respiratory depression, and bowel obstruction. METHODS: We conducted a retrospective analysis of the Premier Database (January 2012 to September 2015) including cholecystectomy patients who received either IV APAP or oral APAP. Differences in LOS, hospitalization costs, mean daily morphine equivalent dose (MED), and potential opioid-related adverse events were estimated. Multivariable logistic regression was performed for the binary outcomes and instrumental variable regressions, using the quarterly rate of IV APAP use for all hospitalizations by hospital as the instrument in two-stage least squares regressions for continuous outcomes. Models were adjusted for patient demographics, clinical risk factors, and hospital characteristics. RESULTS: Among 61,017 cholecystectomy patients, 31,133 (51%) received IV APAP. Subjects averaged 51 and 57 years of age, respectively, in the IV and oral APAP cohorts. In the adjusted models, IV APAP was associated with 0.42 days shorter LOS (95% CI = -0.58 to -0.27; p < .0001), $1,045 lower hospitalization costs (95% CI = -$1,521 to -$569; p < .0001), 2 mg lower average daily MED (95% CI = -3 mg to -0.9 mg; p = .0005), and lower rates of respiratory depression (odds ratio [OR] = 0.89, 95% CI = 0.82-0.97; p = .006), and nausea and vomiting (OR = 0.86, 95% CI = 0.86-0.86; p < .0001). CONCLUSIONS: In patients having cholecystectomy, the addition of IV APAP to perioperative pain management is associated with shorter LOS, lower costs, reduced opioid use, and less frequent nausea/vomiting and respiratory depression compared to oral APAP. These findings should be confirmed in a prospective study comparing IV and oral APAP. PMID- 29192529 TI - Impact of measures to control brucellosis on disease characteristics in humans: experience from an endemic region in the Balkans. AB - AIM: To analyze the impact of measures undertaken to control brucellosis in the Republic of Macedonia on demographic, epidemiological and clinical characteristics of the disease in humans. METHODS: Demographic, epidemiological and clinical characteristics of 340 patients with brucellosis were retrospectively analyzed. Patients were treated at the University Clinic of Infectious Diseases in Skopje during three time periods: 1989-1990 when no national strategy for disease control existed, 2000-2001 when some activities for control were performed and 2011-2014 when an organized and financially supported strategy was accomplished. RESULTS: A drastic decrease of the number of cases of human brucellosis during the last period when compared to the first two ones (3.9 and 3.3 times lower, respectively) was evident. Patients from the third period were significantly older, with median age 41 years (range 4-73) vs. 31 years (3 77) and 34 years (1-74), respectively (p = .013). There were more males (86.6 vs. 73.6% and 63.2%, respectively, p = .002) and the disease was more often acquired professionally (80.6 vs. 60.1% and 59.2%, respectively, p = .006). Fewer patients from the third period had elevated body temperature either as a symptom (50.7 vs. 73.6% and 69.6%, respectively, p = .003), or as a sign (35.8 vs. 55.4% and 56.8%, respectively, p = .011) and less often exhibited focal forms (40.3 vs. 56.8% and 64.0%, respectively, p = .007). CONCLUSION: The national strategy for brucellosis control, which included vaccination of small ruminants, resulted in a decrease of human brucellosis cases in the Republic of Macedonia and there was a tendency to milder disease manifestations. PMID- 29192530 TI - Cost-effectiveness analysis of infliximab, adalimumab, golimumab and vedolizumab for moderate to severe ulcerative colitis in Spain. AB - OBJECTIVES: Assess the efficiency of biologic treatment for moderate to severe ulcerative colitis (UC) which are indicated and financed for this pathology by Spain. METHODS: A Markov model was constructed to simulate the progression in a cohort of patients with moderate to severe UC. The perspective chosen was National Health Service with an over 10 years of time horizon, with a discount rate of 3%, and established threshold of ?30,000/quality-adjusted life-year (QALY). RESULTS: The comparison between infliximab versus adalimumab achieved an incremental cost-effectiveness ratio (ICER) of ?45,582/QALY, with a 0.900 QALYs difference of efficacy and an incremental cost of ?41,036. Golimumab versus adalimumab reached an ICER of ?2,175,992/QALY, with a difference of 0.001 QALY in efficacy and a raising cost to ?2,611. The comparison between vedolizumab with adalimumab achieved an ICER of ?90,532/QALY, 0.930 QALYs of difference and an increasing cost of ?84,218. The probabilistic sensitivity analysis shows that adalimumab would be cost-effective in the 65.2% of the simulations, infliximab in the 18.4%, golimumab in the 16.4% and vedulizumab for the 0%. CONCLUSIONS: Among all these drugs studied, adalimumab is the most cost-effective drug for the treatment of moderate to severe UC for a threshold of ?30,000/QALY in Spain. PMID- 29192531 TI - Comparison of acute to chronic ratios between silver and gold nanoparticles, using Ceriodaphnia dubia. AB - As integration of nanoparticles (NPs) into products becomes more common, the need to address the paucity of chronic hazard information for aquatic environments required to determine risk potential increases. This study generated acute and chronic toxicity reference values for Ceriodaphnia dubia exposed to 20 and 100 nm silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) to generate and evaluate potential differences in acute-to-chronic ratios (ACR) using two different feeding methods. A modified feeding procedure was employed alongside the standard procedures to investigate the influence of food on organism exposure. An 8-h period before food was added allowed direct organism exposure to NP dispersions (and associated ions) without food-to-NP interactions. The AgNPs [chronic lethal median concentrations (LC50) between 18.7 and 31.9 ug/L] were substantially more toxic than AuNPs (LC50 = 21 507 to >26 384 ug/L). The modified chronic testing method resulted in greater sensitivity in AgNPs exposures. However, the modified feeding ration had less of an effect in exposures to the larger (100 nm) AgNPs compared to smaller particles (20 nm). The ACRs for AgNPs using the standard feeding ration were 1.6 and 3.5 for 20 nm and 100 nm, respectively. The ACRs for AgNPs using the modified feeding ration were 3.4 and 7.6 for 20 nm and 100 nm NPs, respectively. This supports that the addition of the standard feeding ration decreases C. dubia chronic sensitivity to AgNPs, although it must also be recognized organisms may be sensitized due to less access to food. The ACRs for 20 nm and 100 nm AuNPs (standard ration only) were 4.0 and 3.0, respectively. It is important to also consider that dissolved Ag+ ions are more toxic than AgNPs, based on both acute toxicity values in the cited literature and chronic toxicity thresholds generated in this study that support existing thresholds that Ag+ are likely protective of AgNPs effects.

PMID- 29192533 TI - Cardiovascular mortality trends in non-Hodgkin's lymphoma: a population-based cohort study. AB - BACKGROUND: Non-Hodgkin's lymphoma (NHL) survivors are at a higher risk of cardiovascular diseases (CVDs). METHODS: A population-based study was conducted to investigate the cardiovascular mortality trends to identify NHL survivors at the highest risk. RESULTS: The CVDs mortality was the second most common cause of death (13.07%) after NHL. There were more patients >= 60 years old in the cardiovascular group (87.2%), P < 0.001. Patients who died from CVDs had the best survival while patients who died from NHL had a significantly lower mean survival. The overall survival rate was 92.4%. Consistently, older age, unmarried, male patients, not recently diagnosed with NHL and not receiving radiation and/or surgery were associated with a worse survival across all models. The black race and stage IV only had a worse cardiovascular specific survival (CVSS). CONCLUSIONS: Although the CVSS improved over time, the mortality from the CVDs is still the second most common cause of death after NHL. Older age, not married, black, male patients, not recently diagnosed with NHL, with an advanced stage and not receiving radiation and/or surgery were associated with a worse survival. Risk factor modification along with CVDs screening should be intensified in NHL patients with these mortality predictors. PMID- 29192534 TI - Intensive Communicative Therapy Reduces Symptoms of Depression in Chronic Nonfluent Aphasia. AB - BACKGROUND: Patients with brain lesions and resultant chronic aphasia frequently suffer from depression. However, no effective interventions are available to target neuropsychiatric symptoms in patients with aphasia who have severe language and communication deficits. OBJECTIVE: The present study aimed to investigate the efficacy of 2 different methods of speech and language therapy in reducing symptoms of depression in aphasia on the Beck Depression Inventory (BDI) using secondary analysis (BILAT-1 trial). METHODS: In a crossover randomized controlled trial, 18 participants with chronic nonfluent aphasia following left hemispheric brain lesions were assigned to 2 consecutive treatments: (1) intensive language-action therapy (ILAT), emphasizing communicative language use in social interaction, and (2) intensive naming therapy (INT), an utterance centered standard method. Patients were randomly assigned to 2 groups, receiving both treatments in counterbalanced order. Both interventions were applied for 3.5 hours daily over a period of 6 consecutive working days. Outcome measures included depression scores on the BDI and a clinical language test (Aachen Aphasia Test). RESULTS: Patients showed a significant decrease in symptoms of depression after ILAT but not after INT, which paralleled changes on clinical language tests. Treatment-induced decreases in depression scores persisted when controlling for individual changes in language performance. CONCLUSIONS: Intensive training of behaviorally relevant verbal communication in social interaction might help reduce symptoms of depression in patients with chronic nonfluent aphasia.

No Additional Effects of Prism Adaptation on Neglect Recovery in the Subacute Phase Poststroke: A Randomized Controlled Trial. AB - BACKGROUND: Patients with neglect ignore or respond slower to contralesional stimuli. Neglect negatively influences independence in activities of daily living (ADL). Prism adaptation (PA) is one of the most frequently studied treatments, yet there is little evidence regarding positive effects on neglect behavior in ADL. OBJECTIVE: To assess whether PA in the subacute phase ameliorates neglect in situations of varying complexity. METHODS: A total of 70 neglect patients admitted for inpatient stroke rehabilitation received either PA or sham adaptation (SA) for 2 weeks, with full access to standard treatment. There were 7 time-dependent measurements (baseline and 1-4, 6, and 14 weeks after start of treatment). The primary outcome was change of neglect as observed during basic ADL with the Catherine Bergego Scale (CBS). Secondary outcomes were changes in performance on a dynamic multitask (ie, the Mobility Assessment Course [MAC]) and a static paper-and-pencil task (ie, a shape cancellation task [SC]). RESULTS: In all, 34 patients received PA and 35 SA. There were significant time-dependent improvements in performance as measured with the CBS, MAC, and SC (all F > 15.57; P < .001). There was no significant difference in magnitude of improvement between groups on the CBS, MAC, and SC (all F < 2.54; P > .113]. CONCLUSIONS: No beneficial effects of PA over SA in the subacute phase poststroke were observed, which was comparable for situations of varying complexity. Heterogeneity of the syndrome, time post-stroke onset, and the content of treatment as usual are discussed. Basic knowledge on subtypes and recovery patterns would aid the development of tailored treatment. PMID- 29192538 TI - The Impact of a Childhood Cancer Diagnosis on the Children and Siblings' School Attendance, Performance, and Activities: A Qualitative Descriptive Study. AB - Families of children with cancer are confronted with unexpected out-of-pocket expenses and productivity costs associated with the diagnosis. One productivity cost that falls on children is the impact of cancer on children's school attendance, performance, and activities (eg, play, friendships, and socialization). Nested within the Childhood Cancer Cost Study, this qualitative descriptive study used convenience sampling to recruit and interview parents of children newly diagnosed with cancer. Content analysis techniques were used to inductively descriptive the semistructured interview data. Sixty-six parents of 65 children with cancer and of 73 siblings participated. The most commonly reported productivity loss in children with cancer was school absenteeism mainly due to cancer treatment. Children fell behind their classmates academically and lost important social time with peers. A few siblings also fell behind their peers primarily due to limited parental attention. Parents adopted various strategies to lessen the impact of the diagnosis on their children's school attendance, performance, and activities. Providing parents with additional resources and support may optimize their children's academic and social reintegration into school. PMID- 29192539 TI - Experimental chronic cerebral hypoperfusion results in decreased pericyte coverage and increased blood-brain barrier permeability in the corpus callosum. AB - Murine chronic cerebral hypoperfusion (CCH) results in white matter (WM) injury and behavioral deficits. Pericytes influence blood-brain barrier (BBB) integrity and cerebral blood flow. Under hypoxic conditions, pericytes detach from perivascular locations increasing vessel permeability and neuronal injury. This study characterizes the time course of BBB dysfunction and pericyte coverage following murine experimental CCH secondary to bilateral carotid artery stenosis (BCAS). Mice underwent BCAS or sham operation. On post-procedure days 1, 3, 7 and 30, corpus callosum BBB permeability was characterized using Evans blue (EB) extravasation and IgG staining and pericyte coverage/count was calculated. The BCAS cohort demonstrated increased EB extravasation on postoperative days 1 ( p = 0.003) 3 ( p = 0.002), and 7 ( p = 0.001) when compared to sham mice. Further, EB extravasation was significantly greater ( p = 0.05) at day 3 than at day 30 in BCAS mice. BCAS mice demonstrated a nadir in pericyte coverage and count on post operative day 3 ( p < 0.05, compared to day 7, day 30 and sham). Decreased pericyte coverage/count and increased BBB permeability are most pronounced on postoperative day 3 following murine CCH. This precedes any notable WM injury or behavioral deficits. PMID- 29192540 TI - Thoracoabdominal breathing motion pattern and coordination of professional ballet dancers. AB - Ballet training includes exercises of high and moderate intensities, which require breathing control for a good performance. This study describes the thoracoabdominal motion of professional dancers and compares the breathing patterns between professional dancers and non-dancers. Participants of this study were four male and four female (30.33 +/- 4.64 years) professional dancers and four male and four female (22.75 +/- 1.49 years) non-dancers. The participants executed two breathing manoeuvres while sitting motionless: quiet breathing (QB) and vital capacity (VC). The 3D coordinates of 32 retro-reflective markers positioned on the trunk were used to calculate the volume of the superior thorax, inferior thorax and abdomen. Principal component analysis was applied in the volume variation of each trunk compartment to search for dominant independent variables in a breathing motion pattern. The correlation coefficient was calculated to verify the coordination between the compartments during the breathing manoeuvres. A predominance of the superior thorax or abdomen movement was found in both groups. The professional ballet dancers have an efficient breathing pattern and maintain the same breathing pattern in QB and VC manoeuvres. On the other hand, the non-dancers group showed relevant changes of the breathing pattern to respond to a greater breathing effort, like in VC. PMID- 29192541 TI - Chronic post-traumatic headache in children and adolescents: systematic review of prevalence and headache features. AB - The aim of this systematic review is to determine the prevalence and clinical features of chronic post-traumatic headache (CPTH) in children and adolescents. Literature search of PubMed, Embase, Cochrane databases and Google Scholar was carried out for all studies reporting on CPTH in children and young people under the age of 18 years between January 1980 and November 2016. Search command included post-traumatic headache, postconcussion syndrome, child and adolescent. Demographic data, diagnostic criteria of headache disorders, occurrence of headache after head injury and headache phenotypes were collected. The prevalence of nonspecific 'chronic headache' after head injury in children was 39% and prevalence of CPTH, as defined by the International Classification of Headache Disorders (2004), was 7.6% (95% CI: 5.9-9.7). Migraine-like headache was the most common presentation followed by tension-type headache. Other children had either mixed or unclassified headache disorders. PMID- 29192542 TI - The effects of a simulated occupational kneeling exposure on squat mechanics and knee joint load during gait. AB - Occupational kneeling is associated with an increased risk for tibiofemoral knee osteoarthritis. Forces on the knee in the kneeling posture, as well as the greater incidence of meniscus tears among workers, likely contribute to the increased risk. We hypothesise that an additional mechanism may contribute - altered neuromuscular control due to prolonged high knee flexion. Forty participants (20 male, 20 female) completed an evaluation of gait and squatting before, immediately following, and 30 min following a 30 min simulated occupational kneeling exposure. An increase in the peak external knee adduction moment and a delay in vastus medialis activation onset during walking were observed post-kneeling, as well as increased frontal plane knee motion during squatting. This was the first investigation to find changes in high flexion transitions as a result of kneeling. Greater frontal plane knee motion may increase the risk for meniscal tears, and subsequently, knee osteoarthritis. Practitioner Summary: A 30 min simulated occupational kneeling exposure resulted in small but significant gait changes. The greatest effect was on frontal plane knee movement during squatting, which is especially relevant to occupations requiring frequent kneeling/squatting. This increased motion may indicate an increased risk of injury, which supports a link to knee osteoarthritis. PMID- 29192544 TI - Daughters sense their mother's stress. PMID- 29192545 TI - Cardiovascular, respiratory and sedative effects of intramuscular alfaxalone, butorphanol and dexmedetomidine compared with ketamine, butorphanol and dexmedetomidine in healthy cats. AB - Objectives The aim of the study was to evaluate the cardiorespiratory effects, quality of sedation and recovery of intramuscular alfaxalone-dexmedetomidine butorphanol (ADB) and ketamine-dexmedetomidine-butorphanol (KDB), in cats. Methods Nine adult, healthy cats (6.63 +/- 1.42 kg) were enrolled in a blinded, randomized, crossover experimental design. Cats were sedated twice intramuscularly, once with ADB (alfaxalone 1 mg/kg, dexmedetomidine 0.005 mg/kg, butorphanol 0.2 mg/kg), and once with KDB (ketamine 5 mg/kg, dexmedetomidine 0.005 mg/kg, butorphanol 0.2 mg/kg), in random order. Data collected included heart rate (HR), arterial blood pressure and blood gas analysis, respiratory rate and sedation score. Analysis of variance with Bonferroni post-hoc correction was used for parametric data, and a Wilcoxon signed rank test was used for non parametric data. Significance was set at P <0.05. Results Total sedation time was shorter for ADB (90.71 +/- 15.12 mins vs 147.00 +/- 47.75 mins). Peak sedation was observed within 15 mins in both groups. Quality of recovery was excellent in both groups. HR decreased over time in both groups. Diastolic and mean arterial pressure decreased over time for ADB, becoming significant after 30 mins. All cardiovascular variables were within the clinically acceptable range in both groups. Arterial partial pressure of oxygen was significantly decreased from baseline for KDB at all time points (73 +/- 2.5 mmHg [9.7 +/- 0.3 kPa] vs ADB 83 +/- 2.6 mmHg [11 +/- 0.3 kPa]). Hypoventilation was not observed. Conclusions and relevance Both protocols produced acceptable cardiovascular stability. Sedation and recovery quality were good, albeit sedation was shorter with ADB. Although oxygenation was better maintained in the ADB group, all sedated cats should receive oxygen supplementation. PMID- 29192546 TI - Drip infusion cholangiography with CT in cats. AB - OBJECTIVES: Ultrasonography can detect extrahepatic biliary obstructions. However, visualisation of part of the bile duct using ultrasonography can be technically difficult if there is overlying bowel gas. This study investigated the safety and value of drip infusion cholangiography with computed tomography (DIC-CT) in the visualisation of the bile duct in healthy cats and extrahepatic biliary obstruction in cats with cholelithiasis. METHODS: DIC-CT was performed in three healthy cats and two cats with cholelithiasis. Meglumine iotroxate was administered by intravenous drip infusion over 30 mins. The attenuation value was measured perpendicular to the lumen by a region of interest covering about 50% of the area of the lumen. RESULTS: The bile ducts were visualised successfully with DIC-CT in all healthy cats without any significant adverse events. The attenuation value of the contrast medium was 271 +/- 37 HU. In the two cats with cholelithiasis, the presence or absence of extrahepatic biliary obstruction was determined using DIC-CT without any significant adverse events. The attenuation value of cholelithiasis in the cat with an extrahepatic biliary obstruction was 933 +/- 119 HU. In the cat with no extrahepatic biliary obstruction, the attenuation value of the contrast medium was 249 +/- 53 HU and the attenuation value of cholelithiasis was 167 +/- 28 HU. CONCLUSIONS AND RELEVANCE: DIC-CT visualises bile ducts and detects obstructive biliary disease without significant adverse events. Therefore, it appears to be a safe procedure for visualisation of the bile duct in cats. PMID- 29192547 TI - Finding Salmonella in unusual sites: look before you leap. A case series.

AB - Introduction A standard osteosynthetic material for maxillofacial skeleton is titanium and its alloys. The convenience of degradable material is avoiding of second surgery in cases, where removal of the material is necessary. Magnesium biodegradable alloys have similar mechanic properties as cortical bone - reasonable corrosion and sufficient biologic properties. They might be used in facial skeleton fixation. Materials and methods The study included a total of 16 rabbits, and they were randomly divided into two groups. Each group received two screws (WE4 and titanium as a standard material) in artificially drilled defect into right tibia. Animals were euthanized at four-week intervals. Bone samples with implants underwent microfocus CT scans and were histologically examined. Results WE43 alloys showed fragmentation of the material on the 16th week - statistically significant volume loss was found between weeks 12 and 16. Bone healing around the WE43 screws was of similar quality as around titanium screws, and no adverse effect was noticed. Conclusion The study showed good quality of bone healing around WE43 implants. From this point of view, the WE43 alloy meets the requirements of osteosynthetic material for maxillofacial skeleton. PMID- 29192549 TI - A Single-Dose, Two-Way Crossover, Open-Label Bioequivalence Study of an Amphetamine Extended-Release Oral Suspension in Healthy Adults. AB - OBJECTIVE: The purpose of this study was to compare the pharmacokinetics of a new extended-release amphetamine oral suspension (AMP XR-OS) with a standard extended release mixed amphetamine salts product, Adderall XR(r). METHOD: In this single dose, open-label, randomized, two-period, two-treatment crossover study, 42 healthy adult volunteers received 15 mL of AMP XR-OS in one period and a 30 mg Adderall XR capsule in another period (both containing 18.8 mg of amphetamine base) under fasted conditions. Blood samples were analyzed for d- and l amphetamine concentrations, and pharmacokinetic parameters Cmax, AUC0-5, AUC5 last, and AUCinf were calculated to determine bioequivalence. Safety was monitored throughout the study. RESULTS: The 90% confidence intervals (CIs) for the log-transformed Cmax, AUC0-5, AUC5-last, and AUCinf fell within the accepted 80% to 125% range for establishing bioequivalence for d- and l-amphetamine. The most common adverse events were nausea and decreased appetite. CONCLUSION: AMP XR OS is bioequivalent to Adderall XR in healthy adult participants. PMID- 29192550 TI - Kinematic analysis of proximal-to-distal and simultaneous motion sequencing of straight punches. AB - Consecutive proximal-to-distal sequencing of motion is considered to be integral for generating high velocity of distal segments in many sports. Simultaneous usage of proximal and distal segments as seen in martial arts is by far less well investigated. Therefore, the aim of the study was to characterise and differentiate the concepts of consecutive (CSM) and simultaneous (SSM) sequence of motion in straight reverse punches as practised in Practical Wing Chun. Four experienced martial artists succeeded an eligibility test for technical proficiency in both concepts and performed a total number of 20 straight punches per concept. Eight MX13 Vicon cameras (250 fps) and Visual3D were used for motion capture and analyses. Both motion concepts showed proximal-to-distal sequencing of maximal joint velocities but, in SSM, this was coupled with simultaneous initiation. Key characteristics were: high pelvis momentum and backswing of shoulder and elbow (CSM); and importance of shoulder involvement (SSM). Different ranges of motion, timing aspects and achieved maximal angular velocities distinguished both concepts, which led to differences (p < 0.05) in fist velocity at contact, execution time, distance and horizontal shift of the centre of mass. Proper application of both concepts depends on the environmental setting, situational requirements and individual fighting style. PMID- 29192551 TI - Parent-child attachment: meta-analysis of associations with parenting behaviors in middle childhood and adolescence. AB - Maternal sensitivity predicts mother-child attachment in young children, but no meta-analysis has investigated the link between parenting and parent-child attachment in older children. This study examined the relationship between parent child attachment and multiple components of parenting in children 5-18 years of age. A series of meta-analyses showed that parents of children with more secure attachment are more responsive, more supportive of the child's autonomy, use more behavioral control strategies, and use less harsh control strategies. Parents of children with more avoidant attachment were less responsive and used less behavioral control strategies. Ambivalent attachment was not significantly related to any of the parenting behaviors, and there were not enough studies to reliably test the relationship between disorganized attachment and parenting. There were few significant moderators. The findings inform new areas for future research, as well as family interventions for at-risk youth.

MATERIALS & METHODS: Prospective observational study evaluating the association of 124 polymorphisms with the response to adalimumab or infliximab (PASI75) in patients with moderate-to-severe plaque psoriasis at 3 months (n = 95) and 6 months of treatment (n = 90). Significant SNPs for univariate analysis were subjected to multivariate analysis. RESULTS: Five SNPs were associated with PASI75 at 3 months: rs6661932 (IVL), rs2546890 (IL-12B), rs2145623 (NFKBIA), rs9304742 (ZNF816A) and rs645544 (SLC9A8). Furthermore, rs1061624 (TNFR1B) was associated with PASI75 at 6 months. CONCLUSION: Nevertheless, these biomarkers should be validated in large-scale studies before implementation in clinical practice.

AB - Diffuse large B-cell lymphoma (DLBCL) is the most common type of lymphoma in dogs. We evaluated Ki67 immunoexpression and mitotic index (MI) in dogs diagnosed with DLBCL and treated with a 19-wk CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) protocol. Twenty-nine lymph node samples from dogs diagnosed with DLBCL were analyzed for Ki67 immunostaining, and positive cells present in 1 cm2 were counted in a grid reticle for comparison of survival times above and below the means. The Ki67 mean was 107, and the MI mean was 21. There was a significant ( p < 0.05) difference in median survival time between Ki67 immunostaining above and below the mean, with no difference in MI groups. Ki67 values >107 positive cells per 5 HPF counted in a grid reticle were associated with shorter survival times in dogs with DLBCL treated with a 19-wk CHOP-based protocol. PMID- 29192555 TI - Nanoemulsions of sulfonamide carbonic anhydrase inhibitors strongly inhibit the growth of Trypanosoma cruzi. AB - Sulfonamide carbonic anhydrase (CA, EC 4.2.1.1) inhibitors targeting the alpha class enzyme from the protozoan pathogen Trypanosoma cruzi, responsible of Chagas disease, were recently reported. Although many such derivatives showed low nanomolar activity in vitro, they were inefficient anti-T. cruzi agents in vivo. Here, we show that by formulating such sulfonamides as nanoemulsions in clove (Eugenia caryophyllus) oil, highly efficient anti-protozoan effects are observed against two different strains of T. cruzi. These effects are probably due to an enhanced permeation of the enzyme inhibitor through the nanoemulsion formulation, interfering in this way with the life cycle of the pathogen either by inhibiting pH regulation or carboxylating reactions in which bicarbonate/CO2 are involved. This type of formulation of sulfonamides with T. cruzi CA inhibitory effects may lead to novel therapeutic approaches against this orphan disease.

PMID- 29192556 TI - Bacterial endotoxin (lipopolysaccharide) binds to the surface of gold nanoparticles, interferes with biocorona formation and induces human monocyte inflammatory activation. AB - Nanoparticles (NPs) are easily contaminated by bacterial endotoxin (lipopolysaccharide [LPS]). The presence of LPS can be responsible for many immune/inflammatory effects attributed to NPs. In this study, we examined the effects of LPS adsorption on the NP surface on the formation of a biocorona in biological fluids and on the subsequent inflammation-inducing activity of NPs. Different gold (Au) NPs with sizes ranging from 10 to 80 nm and with different surface functionalization (sodium citrate, lipoic acid, and branched polyethyleneimine (BPEI), or polyethylene glycol (PEG)) were exposed to E. coli LPS under different conditions. The binding capacity of LPS to the surface of AuNPs was dose- and time-dependent. LPS attached to sodium citrate and lipoic acid coatings, but did not adhere to BPEI- or PEG-coated NPs. By computational simulation, the binding of LPS to AuNPs seems to follow the Langmuir absorption isotherm. The presence of LPS on AuNP surface interfered and caused a decrease in the formation of the expected biomolecular corona upon incubation in human plasma. LPS-coated AuNPs, but not the LPS-free NPs, induced significant inflammatory responses in vitro. Notably, while free LPS did also induce an anti inflammatory response, LPS bound to NPs appeared unable to do so. In conclusion, the unintentional adsorption of LPS onto the NP surface can affect the biocorona formation and the inflammatory properties of NPs. Thus, for an accurate interpretation of NP interactions with cells, it is extremely important to be able to distinguish the intrinsic NP biological effects from those caused by biologically active contaminants such as endotoxin. PMID- 29192559 TI - A refined and translationally relevant model of chronic DSS colitis in BALB/c mice. AB - Inflammatory bowel diseases (IBD) are chronic relapsing disorders of the gastrointestinal tract. Several mouse models for IBD are available, but the acute dextran sulfate sodium (DSS)-induced colitis model is mostly used for preclinical studies. However, this model lacks chronicity and often leads to significant loss of mice. The aim of this study was to establish a refined and translationally relevant model of DSS chronic colitis in BALB/c mice. In the first part, we compared several standard therapeutic (ST) treatments for IBD in the acute DSS colitis model to identify the optimal treatment control for a DSS colitis model as compared to literature data. In the second part, we tested the two most effective ST treatments in a refined model of chronic DSS colitis. Cyclosporine A (CsA) and 6-thioguanine (6-TG) caused considerable reduction of clinical scores in acute DSS colitis. The clinical outcome was confirmed by the results for colon length and by histopathological evaluation. Moreover, CsA and 6-TG considerably reduced mRNA expression of several pro-inflammatory cytokines in spleen and colon. Both compounds also showed a substantial therapeutic effect in the refined model of chronic DSS colitis with regard to clinical scores and histopathology as well as the expression of inflammatory markers. The refined model of chronic DSS colitis reflects important features of IBD and is well suited to test potential IBD therapeutics.

However, certain doubts have arisen around probiotics, because of the beneficial effects of these microorganisms are not clear yet, and in many occasions those beneficial effects have not been proven. Therefore, it would be of interest if these probiotic strains were able to acquire new attributes to allow them improve and increase their beneficial characteristics. Genetic engineering can be used for human applications; for instance, the resistance to antibiotics is removed and the probiotic bacteria are modified in its own DNA. This process can be achieved by: (1) the use of food-grade vectors derived from lactic acid bacteria and/or bifidobacteria cryptic plasmids, (2) the genes integration or deletion in the chromosome of the probiotic strain, by site specific recombination using the attP/integrase system, or by homologous recombination, using either suicide vectors, (3) using the clustered regularly interspaced short palindromic repeats (CRISPR) and the CRISPR-associated (Cas) nuclease. Through genetic engineering, the knowledge of probiotic strains as well as its use could be improved, and the doubts about probiotics could be crumped. PMID- 29192562 TI - Cerebral microcirculatory alterations and the no-reflow phenomenon in vivo after experimental pediatric cardiac arrest. AB - Decreased cerebral blood flow (CBF) after cardiac arrest (CA) contributes to secondary ischemic injury in infants and children. We previously reported cortical hypoperfusion with tissue hypoxia early in a pediatric rat model of asphyxial CA. In order to identify specific alterations as potential therapeutic targets to improve cortical hypoperfusion post-CA, we characterize the CBF alterations at the cortical microvascular level in vivo using multiphoton microscopy. We hypothesize that microvascular constriction and disturbances of capillary red blood cell (RBC) flow contribute to cortical hypoperfusion post-CA. After resuscitation from 9 min asphyxial CA, transient dilation of capillaries and venules at 5 min was followed by pial arteriolar constriction at 30 and 60 min (19.6 +/- 1.3, 19.3 +/- 1.2 um at 30, 60 min vs. 22.0 +/- 1.2 um at baseline, p < 0.05). At the capillary level, microcirculatory disturbances were highly heterogeneous, with RBC stasis observed in 25.4% of capillaries at 30 min post CA. Overall, the capillary plasma mean transit time was increased post-CA by 139.7 +/- 51.5%, p < 0.05. In conclusion, pial arteriolar constriction, the no reflow phenomenon and increased plasma transit time were observed post-CA. Our results detail the microvascular disturbances in a pediatric asphyxial CA model and provide a powerful platform for assessing specific vascular-targeted therapies. PMID- 29192563 TI - Use of a Microcatheter to Cannulate the Contralateral Gate in Endovascular Aortic Repair. AB - Cannulation of the contralateral gate is a crucial step in endovascular aortic aneurysm repair (EVAR) to configure a modular stent-graft. Most commonly, the contralateral gate is cannulated retrogradely using a conventional catheter and hydrophilic guide wire; if this maneuver fails, a cross-over technique or additional access in the left brachial artery in association with a contralateral femoral snare catheter may be used. A cross-over technique using a microcatheter and a contralateral snare catheter might be a valuable alternative to cannulate the contralateral gate, especially in cases where there is a partly nondeployed contralateral stent-graft limb. PMID- 29192564 TI - Rare case of atypical parkinsonism: why family history is important. AB - We discuss the clinical presentation and assessment of a middle aged previously fit and well man who presented with two episodes of syncope to the cardiologists followed by the development of a rapidly progressive parkinsonian syndrome a couple of years later, which was not responsive to standard dopaminergic replacement therapies. Magnetic resonance imaging scan of the brain was normal and a DAT SPECT scan showed reduced dopamine uptake in the basal ganglia. On further enquiry, a family history of a similar presentation in his first cousin was elicited and that cousin had tested positive for a mutation in the PRNP gene. Subsequently, he also tested positive for A117V mutation in the PRNP gene, confirming familial Creutzfeld Jakob disease. Familial Creutzfeld Jakob disease presenting with parkinsonism is rare in clinical practice, but it is something that neurologists and geriatricians running movement disorder clinics should be aware of, as this is a rapidly progressive and uniformly fatal condition with inheritance risks to family members.

PMID- 29192566 TI - [Breastfeeding in a multi-ethnic population: changes between 2009 and 2015]. AB - OBJECTIVE: To examine changes in breastfeeding rates in 0 to 6 month old infants in Amsterdam, the Netherlands, over the period from 2009 to 2015, for the total population as well as for various ethnic groups. DESIGN: Cross-sectional study. METHOD: Breastfeeding rates were examined for the period from 2009 to 2015 in 165,420 registrations of 75,543 infants at the ages of 2 weeks, 3 months and 6 months for the entire Amsterdam population and for various ethnic groups. Differences were analysed using chi2 tests. RESULTS: The weighted percentage of total breastfeeding (exclusive breastfeeding as well as a combination of breast and formula feeding) increased in the entire Amsterdam study population over the period from 2009 to 2015 (2 weeks: 87.8% to 89.1%; 3 months: 61.6% to 63.6%; 6 months: 39.5% to 42.2%). Increases were mainly the result of increases in weighted percentages for exclusive breastfeeding. The highest exclusive breastfeeding rates were observed among the Turkish ethnic group, the lowest among the Antillean/Aruban and Surinamese groups. CONCLUSION: Percentages for total breastfeeding as well as exclusive breastfeeding in Amsterdam rose over the period from 2009 to 2015, but there is room for improvement. Breastfeeding promotion, whether or not in combination with formula feeding, may be of particular benefit to children of Surinam or Antillean/Aruban descent. Before ethnicity-specific interventions can be implemented, more insight is needed in the reasons for the low breastfeeding rates in specific groups. PMID- 29192567 TI - [Assessment of physicians with a foreign diploma; results of 10 years of testing of physicians with a foreign diploma]. AB - OBJECTIVE: To determine the result of the assessment procedure, initiated on 1 December 2005, for physicians with a foreign diploma who wish to practice in the Netherlands. DESIGN: Retrospective, descriptive study. METHOD: The Commission for Foreign Healthcare Graduates (CBGV) collected data on physicians with a foreign diploma who followed the procedure for requesting a declaration of professional competence and admission to the Dutch Individual Healthcare Professions (BIG) register between December 2005 - December 2015. The procedure comprises a language and communication test, followed by tests of professional competence. On the grounds of the test results, the CBGV can decide if a physician should follow a specific training course. The number of physicians who ultimately obtained BIG registration was determined. RESULTS: During the study period, 183 of the 206 physicians with a foreign diploma passed the general knowledge and skills tests. A total of 176 of the 183 physicians took the professional competence tests. In 43 (25%) of them no shortcomings in knowledge and skills were seen. They were registered in the BIG register for a period of supervision. In 129 (73%), shortfalls were made up by means of focused training programme. In 4 (2%) of them no training was possible. On the date of assessment, 137 (78%) physicians were registered. This number is expected to rise to 151 (86%). CONCLUSION: The provision of a further course of training that is focused on the elimination of identified shortcomings in physicians with a foreign diploma, increases the percentage of foreign physicians that are successfully admitted to the BIG register. PMID- 29192568 TI - [Polymyalgia rheumatica: new developments and challenges]. AB - - Polymyalgia rheumatica (PMR) is an inflammatory rheumatic disorder in which inflammation markers, both erythrocyte sedimentation rate (ESR) and CRP values, are often elevated. However, a non-abnormal ESR or CRP value does not preclude the diagnosis.- PMR is an arbitrary diagnosis and presents both diagnostic and therapeutic challenges.- Imaging diagnostics, such as echography, MRI or FDG PET/CT, may potentially be applied more frequently as a second-line investigation when there is doubt concerning the diagnosis. Currently these additional imaging techniques are not applied in first line diagnostics.- Glucocorticoids remain the cornerstone treatment for polymyalgia rheumatica. Often patients react swiftly to this, but in 29-45% of cases an effect is only observed 3-4 weeks later. The treatment course typically lasts 1-3 years.- More research has been conducted into potential glucocorticoid-sparing treatments. Most of the scientific evidence concerns the effectiveness of methotrexate; there is some evidence regarding the effectiveness of azathioprine and leflunomide. Tocilizumab, an IL-6 receptor inhibitor, has shown promise as a treatment, but further evidence is required. PMID- 29192569 TI - [From record keeping to scientific research: obstacles and opportunities for research with electronic health records]. AB - As a result of increasing digitisation of medical record keeping, electronic health records (EHRs) are an attractive source for data reuse. However, such record-based research is still suffering from poor quality of data stored in EHRs. Lack of consent for reuse of data also plays an impeding role, especially in retrospective record-based research. That said, increasing cooperation between healthcare institutions and current attention for EHR organisation also offer opportunities for record-based research. Patient data can be recorded in more standardised ways and in increasingly harmonised EHRs. In addition, if healthcare institutions were to establish a generic consent procedure - preferably with national scope - the potential of EHRs for scientific research could be exploited in considerably better ways. PMID- 29192570 TI - [Patients and physicians creating a research agenda together: the method of the British James Lind Alliance]. AB - The British James Lind Alliance (JLA) has developed a method to allow practitioners, patients and family members together to develop a research agenda for a disease or a form of treatment. In a 'priority setting partnership', they gradually establish a top-10 list of the most important unanswered research questions. Input from patients and their relatives is given the same weight when determining priorities as that from practitioners. More than 50 of these top-10 lists have been created so far, one of which was created in the Netherlands. The JLA method combines elements of the two very different methods currently prevailing in the Netherlands: the dialog model, developed by the VU and the 'health care evaluation agenda', developed by the Dutch Association of Medical Specialists. The JLA method is quite practicable and leads to new research questions. The biggest advantage is that it leads to a dialogue between creators and users of knowledge about what the relevant research questions are.

AB - OBJECTIVE: To determine the degree of agreement between delirium experts on the diagnosis of delirium based on exactly the same information, and to assess the sensitivity of delirium screening methods used by clinical nurses. DESIGN: Prospective observational longitudinal study. METHOD: Older patients (>= 60 years) who underwent major surgery were included. During the first three days after surgery they had a standardised cognitive screening test which was recorded on video. Two delirium experts independently evaluated these videos and the information from the patient records. They classified the patients as having 'no delirium', 'possible delirium' or 'delirium'. If there was disagreement, a third expert was consulted. The final classification, based on consensus of two or three delirium experts, was compared with the result of the delirium screening carried out by the clinical nurses. RESULTS: A total of 167 patients were included and 424 postoperative classifications were obtained. The agreement between the experts was 0.61 (95% confidence interval (CI): 0.53-0.68), based on Cohen's kappa. In 89 (21.0%) of the postoperative classifications there was no agreement between the experts and a third expert was consulted. The nurses using the delirium screening tools recognised 32% of the cases that had been classified as delirium by the experts. CONCLUSION: There was considerable disagreement between the classifications of individual delirium experts, based on exactly the same information, indicating the difficulty of the diagnosis. Furthermore, the sensitivity of the delirium screening tools used by the clinical nurses was poor. Further research should focus on the development of objective methods for recognising delirium.

The wheezing responded quickly to asthma treatment. The stridor, however, was caused by a significant narrowing of the trachea between the branching of a tracheal bronchus ('bronchus suis' or ' pig bronchus') and the main carina.

She was admitted with a varicella-zoster virus (VZV) primo-infection complicated by pneumonia and hepatitis. The patient was successfully treated with aciclovir. Adult VZV primo-infections are uncommon in Dutch natives but occur more often in immigrants from countries with a temperate climate where less people are infected during childhood. PMID- 29192575 TI - [Current dilemmas on the transmission of hepatitis E virus]. AB - Immunocompromised patients are especially at risk for developing chronic hepatitis E virus (HEV) infection, which may result in progressive liver disease and cirrhosis. In addition, treatment of chronic HEV infection in these patients often includes dose reduction of immunosuppressive therapy and this may lead to severe flare-ups of the underlying condition or even rejection of transplant material. Therefore prevention of HEV transmission is being more and more recognised as an essential step to stop increasing HEV seroprevalence. The Dutch National Institute for Public Health and the Environment (RIVM) has recently warned immunocompromised patients following haematopoietic stem cell and solid organ transplantations for the risk of infection by HEV through eating of contaminated products from pig meat. Furthermore, the Dutch blood bank recently decided to start screening all blood products for HEV to prevent iatrogenic transmission of HEV. We describe two patients with HEV infection and discuss risk of infection for immunocompromised patients, transmission routes and the importance of prevention of iatrogenic transfusion related transmission.

This milk might give the infant certain advantages over formula milk, and the potential advantages are reviewed in this commentary. It is concluded that there are advantages to breastfeeding, but that these are limited for an infant in an industrialised country receiving adequate formula milk. Breastfeeding should be encouraged, but there is insufficient reason for a mother who either is not able or not willing to breastfeed to feel guilty about not doing so.

AB - Nonspecific lower back pain is frequently encountered in primary care, with 25 50% of cases following a chronic course. Over recent decades, a large body of research has focused on the effectiveness of both pharmacological and non pharmacological treatments. However, hardly any effective interventions have been identified and the overall strength of evidence is low. We argue that the reason for these disappointing results lies in the 'nonspecific' nature of back pain. It is widely recognised that the causes for nonspecific back pain are not only biologically, but also psychologically and socially determined. Future research should emphasise aetiology and prognosis in order to enhance the development of tailored interventions. PMID- 29192578 TI - [Nitrous oxide-induced polyneuropathy]. AB - Nitrous oxide, laughing gas, is used as a party drug to achieve a euphoric effect. It has been gaining popularity in recent years and is considered a relatively innocent substance. Nitrous oxide is known to cause subacute degeneration of the spinal cord by inactivation of active vitamin B12. Vitamin B12 plays an essential role in the synthesis of myelin. Hence, vitamin B12 deficiency can lead to degeneration of the dorsal and lateral columns of the spinal cord. Polyneuropathy is a less known complication. We present a 17-year old woman and a 19-year-old man with subacute axonal polyneuropathy caused by laughing gas abuse. Abstinence of laughing gas and treatment with intramuscular and oral vitamin B12 suppletion respectively have led to improvement of their symptoms. Our cases demonstrate a less-known but treatable complication of laughing gas. PMID- 29192579 TI - [Heterogeneity of delirium cannot be captured by a simple diagnostic instrument]. AB - The latest criteria for delirium (DSM-5) still encompass a very heterogeneous group of patients, as both risk factors and causes differ greatly between patients. This makes it unlikely that a single biomarker (e.g. an EEG signal) can be a valid and reliable diagnostic tool in clinical practice. Researchers should be very aware of this heterogeneity, as striving for uniform biomarkers would otherwise result in a considerable waste of research effort. In clinical practice, the delineation of delirium syndrome from dementia and coma using these DSM-5 criteria remains challenging. We state that patient outcomes can probably be improved most by interprofessional, personalised management and the monitoring of vulnerable patients during their individual disease trajectories. PMID- 29192580 TI - Copy Number Variants and Exome Sequencing Analysis in Six Pairs of Chinese Monozygotic Twins Discordant for Congenital Heart Disease. AB - Congenital heart disease (CHD) is one of the most common birth defects. More than 200 susceptibility loci have been identified for CHDs, yet a large part of the genetic risk factors remain unexplained. Monozygotic (MZ) twins are thought to be completely genetically identical; however, discordant phenotypes have been found in MZ twins. Recent studies have demonstrated genetic differences between MZ twins. We aimed to test whether copy number variants (CNVs) and/or genetic mutation differences play a role in the etiology of CHDs by using single nucleotide polymorphism (SNP) genotyping arrays and whole exome sequencing of twin pairs discordant for CHDs. Our goal was to identify mutations present only in the affected twins, which could identify novel candidates for CHD susceptibility loci. We present a comprehensive analysis for the CNVs and genetic mutation results of the selected individuals but detected no consistent differences within the twin pairs. Our study confirms that chromosomal structure or genetic mutation differences do not seem to play a role in the MZ twins discordant for CHD.

AB - Diurnal preference (e.g., being an owl or lark) has been associated with several psychiatric disorders including bipolar disorder (BP), major depressive disorder, and substance use disorders. Previous large-scale genome-wide association studies (GWAS) aimed at identifying genetic influences on diurnal preference have exclusively included subjects of European ancestry. This study examined the genetic architecture of diurnal preference in two minority samples: a young adult sample of Mexican Americans (MAs), and a family-based sample of American Indians (AIs). Typed or imputed variants from exome chip data from the MA sample and low pass whole-genome sequencing from the AI cohort were analyzed using a mixed linear model approach for association with being an owl, as defined by a usual bedtime after 23:00 hrs. Genetic risk score (GRS) profiling detected shared genetic risk between evening preference and related disorders. Four variants in KIAA1549 like (KIAA1549L), a gene previously associated with attempted suicide in bipolar patients, were suggestively associated with being an owl at p < 1.82E-05; post hoc analyses showed the top variant trending in both the MA and AI cohorts at p = 2.50E-05 and p = .030, respectively. Variants associated with BP at p < .03 from the Psychiatric Genomics Consortium nominally predicted being an owl in the MA/AI cohort at p = .012. This study provides some additional evidence that genetic risk factors for BP also confer risk for being an owl in MAs/AIs and that evening preference may be a useful endophenotype for future studies of BP.

PMID- 29192587 TI - The proportion of asymptomatic recurrence after catheter ablation of atrial fibrillation in patients with a pacemaker for sick sinus syndrome. AB - BACKGROUND: Catheter ablation (CA) of paroxysmal atrial fibrillation (PAF) is an effective treatment. However, the frequency of asymptomatic AF recurrence after CA in patients with PAF and sick sinus syndrome (SSS) is not clear. The aim of this study was to elucidate the real AF recurrence after CA in patients with PAF and a pacemaker for SSS. METHODS AND RESULTS: Fifty-one consecutive patients (mean age 66.6 +/- 7.0 years, male 34) with PAF and SSS and pacemakers underwent CA. All patients were followed at 1, 3, 6, 9, and 12 months after the CA using a 12-lead ECG, Holter-ECG, and 1-month event recorder as a conventional follow-up. In addition, the pacemakers were interrogated every 12 months. During a 5-year follow-up after the final CA procedure, AF recurrences were observed in 7 patients (13.7%) with a conventional follow-up, including 1 (2.0%) asymptomatic patient. Pacemaker-interrogation revealed another 10 patients (19.6%) with asymptomatic AF recurrences. Ultimately, the conventional follow-up plus pacemaker-interrogation provided a higher incidence of AF recurrences (P = 0.009). Multiple CA procedures contributed to a significant increase in the AF free survival rate at 5 years: 58.6% after a single CA and 86.0% after multiple CA procedures with a conventional follow-up, but which decreased to 40.6% and 60.9% with a conventional follow-up plus a pacemaker interrogation, respectively. CONCLUSIONS: One-third of PAF patients with SSS and pacemakers recurred after multiple CA sessions. However, 65% of them were asymptomatic and difficult to be identified with conventional follow-up. Pacemaker interrogation significantly increased the detection rate of AF-recurrence. PMID- 29192585 TI - Yeast eIF4A enhances recruitment of mRNAs regardless of their structural complexity. AB - eIF4A is a DEAD-box RNA-dependent ATPase thought to unwind RNA secondary structure in the 5'-untranslated regions (UTRs) of mRNAs to promote their recruitment to the eukaryotic translation pre-initiation complex (PIC). We show that eIF4A's ATPase activity is markedly stimulated in the presence of the PIC, independently of eIF4E*eIF4G, but dependent on subunits i and g of the heteromeric eIF3 complex. Surprisingly, eIF4A accelerated the rate of recruitment of all mRNAs tested, regardless of their degree of structural complexity. Structures in the 5'-UTR and 3' of the start codon synergistically inhibit mRNA recruitment in a manner relieved by eIF4A, indicating that the factor does not act solely to melt hairpins in 5'-UTRs. Our findings that eIF4A functionally interacts with the PIC and plays important roles beyond unwinding 5'-UTR structure is consistent with a recent proposal that eIF4A modulates the conformation of the 40S ribosomal subunit to promote mRNA recruitment. PMID- 29192589 TI - Figure-of-eight suture for venous hemostasis in fully anticoagulated patients after atrial fibrillation catheter ablation. AB - INTRODUCTION: Limited data exists for types of venous closure and its associated complications in patients after atrial fibrillation (AF) catheter ablation. We evaluated the subcutaneous figure-of-eight closure (FO8) for achieving venous hemostasis after AF catheter ablation compared to manual pressure. METHODS: 284 consecutive patients that underwent AF catheter ablation by two operators were included. All patients received continuous therapeutic warfarin or interrupted novel oral anticoagulants (NOAC) and heparin (ACT300-400 s) without reversal. Patients were divided into two groups: 1) sheaths were left in place and pulled once ACT < 180 s, with hemostasis being achieved with manual pressure (MP); and 2) a subcutaneous FO8 suture closed the venous access site immediately after the ablation on each groin site and sheaths were removed immediately after the ablation despite full anticoagulation with heparin and warfarin or interrupted NOAC. Sutures were removed after four hours, and the patients laid flat for an additional two hours. RESULTS: The MP group (n = 105) was similar to the FO8 group (n = 179). Time in bed was 573 +/- 80 min for MP group vs. 373 +/- 49 min for FO8 group (p < 0.0001). Eleven hematomas were seen in the MP group compared to seven in the FO8 group (P = 0.041). CONCLUSIONS: In fully anticoagulated patients undergoing AF catheter ablation, excellent hemostasis was achieved with figure-of-eight sutures, with no major vascular complications, a lower hematoma rate, and a significantly shorter flat-time-in-bed compared to manual pressure. PMID- 29192590 TI - Catheter ablation in the treatment of electrical storm: Integrative review. AB - BACKGROUND: The incidence of electrical storm (ES) has been increasing with the rise of the indicated uses of implantable cardioverter defibrillators (ICDs). It is estimated that 20% of patients will evolve to have this complication. Ablative therapy stands out as the treatment for this condition when it is refractory to antiarrhythmic treatment. The objective was to define the current role of catheter ablation in the treatment of electrical storm. METHODS: An integrative literature review was performed using the PubMed and BVS databases. All identified articles were screened and verified for eligibility by the authors. RESULTS: Twenty-five out of the initial 951 articles were used in the final analysis. The categories listed for analysis included indication for ablation in ES, modality of the approach, therapeutic success, complications related to the procedure, mortality and cardiovascular follow-up and alternative therapeutic modalities by frequency of these categories in the articles researched. CONCLUSION: Catheter ablation is the initial therapy for patients with ischemic cardiomyopathy (ICM) and ES. The endocardial approach presents more relevant success rates than the other therapeutic methods presented.

AB - A 79-year-old woman who underwent catheter ablation for paroxysmal atrial fibrillation presented with Torsades de Pointes (TdP). Aggravation of prolonged QT interval which is most likely due to neural modulation by catheter ablation, played major role in the initiation of TdP. The patient was successfully treated with isoproterenol during acute stage and discharged after stabilization without implantation of permanent pacemaker or implantable cardioverter defibrillator.

AB - We present a case of a 37-year-old female who complained of frequent palpitations caused by an atrial tachycardia and atrial premature contractions. Angiography revealed that the coronary sinus was occluded at the ostium and connected to a persistent left superior vena cava. An electrophysiological study and three dimensional mapping revealed that the origin of the atrial tachycardia and atrial premature contractions was at the coronary sinus ostium in the right atrium. After repeat applications of radiofrequency energy at that site, no further atrial tachycardia or atrial premature contractions were induced by atrial burst pacing. To the best of our knowledge, this is the first report of an atrial tachycardia originating from an occluded coronary sinus ostium.

AB - Multi-site multi-polar left ventricular pacing through the coronary sinus (CS) may be preferred over endocardial right ventricular or surgical epicardial pacing in the presence of tricuspid valve disease. However, the required lead placement can be difficult through a persistent left superior vena cava (PLSVC), as the CS tends to be hugely dilated and side branches tend to have sharp angulations (>90 degrees ) when approached from the PLSVC. Pre-shaped angiography catheters and techniques used for finding venous grafts from the ascending aorta post coronary bypass surgery may help with lead placement in such a situation.

AB - A 58-year-old man undergoing cardiac resynchronization therapy with a defibrillator in his right subcostal area fell from his bed, leading to fracture of the right clavicle. Serial radiographs showed dislocation of the distal clavicle 2 months after the initial fracture. Lead parameters dramatically changed after dislocation of the distal clavicle. Radiography indicated that the device leads seemed to be compressed by the distal clavicle in certain positions of the right upper limb. It was likely that various movements of the right upper limb during his daily life insidiously damaged the device leads, leading to the lead breakages.

AB - The somatic mutations in the RAS genes (KRAS and NRAS) are widely associated with non-response to immunotherapies targeting the epidermal growth factor receptor in metastatic colorectal cancer. The detection of these mutations is carried out from tissue biopsies and become mandatory to prescribe these treatments. Nethertheless, this analysis is not possible in about 25% of cases and the development of alternative methods is therefore required. Among them, the search for mutations directly in the blood of patients are promising approaches. Circulating tumor cells (CTCs) represent a particularly relevant direct target. These cells, some of them have inducing-metastasis capabilities, have been able to detach themselves from the primary tumor, then migrate and finally enter into the bloodstream. In this sense, they are particularly resistant to physical chemical and immunological constraints used by the organism to prevent their dissemination. Consequently, they represent a particularly valuable source of information on the most aggressive tumor cells. As a corollary, these cells are very rare requiring particularly highly performant technologies to be detected. In this presentation, we focus mainly on the molecular methods used to detect these mutated RAS cells by analyzing the performance of a solution based on a filtration device followed by detection with digital PCR. Finally, we will discuss the biological significance of these cells before highlighting prospects in colorectal cancer but also in other cancers. PMID- 29192597 TI - Circulating tumour DNA: analytical aspects and clinical applications for metastatic melanoma patients. AB - The management of metastatic melanoma has evolved since the onset of treatments with BRAF inhibitors. In order to predict which patients are likely to respond to these treatments, the therapeutic strategy is now conditioned by the search for the activating mutations of the BRAF gene. Tumor genotyping is routinely performed from DNA extracted from tissue or cellular specimens from the primary tumor, metastases, or neoplastic effusions. Due to their invasiveness, these specimens are rarely repeated during the management. In addition, the analysis of the tumor material requires a pretreatment of the sample (formalin fixation, paraffin inclusion, preparation of tissue sections) and may take up to several weeks, making emergency treatment with BRAF inhibitors impossible. Circulating tumor DNA (ctDNA), released by cancer cells in the blood stream, appears as an alternative to tissue sampling. The pre-analytical conditions are now well defined, and several technological approaches can be used to demonstrate the desired molecular alterations. ctDNA is less affected by tumor heterogeneity, can be collected in a minimally invasive manner and analyzed rapidly. Furthermore, ctDNA can be repeatedly analyzed during follow-up, which makes it possible to envisage its use as a specific tumor marker, in order to monitor the response to the treatment and to detect treatment failure. PMID- 29192598 TI - Personalized medicine, pharmacogenomic and companion biomarker. AB - The aim of this review is to provide a brief overview of personalized medicine, pharmacogenetics and companion tests. Personalized or stratified medicine is a new paradigm in the management of patients, aimed at better taking into account inter-individual variability. The response to drugs' intake varies considerably, depending on the transport and metabolism of the drugs, the target and the pathophysiological characteristics of the organism. Each stage is very variable and can be modified by endogenous factors (pathophysiology, age, sex, genetics...) or exogenous (environmental: taking other medicines, food, tobacco, alcohol...). Pharmacogenetics studies the genetic factors involved in the pharmacological or toxicological response to drugs. Companion tests that are often based on a pharmacogenetic principle aim to identify in a patient's population those who will respond to a given treatment. PMID- 29192599 TI - Medical laboratory technician professional pathologies: a 2006-2016 literature review. AB - The trade of laboratory technician (TL) exposes to many risks to health, because of biological or chemical or physical exposures. But the TL occupation is constantly evolving, the techniques are constantly changing. The purpose of this article is to take stock of the occupational TL pathologies which were recently described in the literature. This is a literature review, based on Medline(r) and Scopus(r) medical databases, on publications between 01/01/2006 and 31/12/2016. The research was conducted in French and English. Only articles about TL in Hospital or Teaching Hospital were selected. Twenty-eight articles were studied. The main infectious pathology described was brucellosis and a case of meningitis was studied. The cutaneous allergies reported concerned sensitization to certain solvents. There was no allergy to latex. Musculoskeletal disorders (MSD) were studied in 4 articles. The main MSDs were low back pain and neck pain. Several articles have alerted on the occurrence of burnout syndrome (BO). However, no prevalence studies were conducted over the period studied. In conclusion, TL can present many occupational pathologies. Few articles studied the prevalence of MSD and BO.

Thus, the magazines in hospital's waiting rooms are handled by patients and visitors whose health and hygiene conditions can vary widely. In this context, we had measured the microbial load on the surface of magazines. Fifteen magazines from 5 waiting rooms of hospital are sampled by agar prints at the areas taken in hand. The agar plates are incubated at 30C for 72h. The colonies are counted and identified by MALDI-TOF mass spectrometry (Vitek(r)-MS). The extraction efficiency of bacteria by the agar print method on the magazines is calculated. All the samples highlight a varied bacterial flora: 32CFU/agar in mean. Isolated bacteria come principally from the skin flora (>60%), but we also isolate potentially pathogenic micro-organisme like S. aureus, E. faecalis, A. viridans and Aspergillus sp. as well as oropharyngeal flora bacteria like A. iwolfii and M. osloensis and fecal like B. stercoris. Some species rarely described in hospital are also isolated such as P. yeei or K. sedentarius. The extraction efficiency of the sampling method on a magazine is 36%. Our study, which is the first to be interested in the bacterial contamination of magazines in hospital, could make them consider as microbial reservoir to be controlled, especially for the most fragile patients. New bacterial identification techniques as the MALDI TOF allow to reveal the presence of rarely described and often underestimated species.

AB - A new directed interval-based tomographic reconstruction algorithm, called non additive interval based expectation maximization (NIBEM) is presented. It uses non-additive modeling of the forward operator that provides intervals instead of single-valued projections. The detailed approach is an extension of the maximum likelihood-expectation maximization algorithm based on intervals. The main motivation for this extension is that the resulting intervals have appealing properties for estimating the statistical uncertainty associated with the reconstructed activity values. After reviewing previously published theoretical concepts related to interval-based projectors, this paper describes the NIBEM algorithm and gives examples that highlight the properties and advantages of this interval valued reconstruction.

AB - We respond to the comments by Dr Yegin by identifying the source of an error in a fit in our original paper but arguing that the lack of a fit does not affect the conclusion based on the raw data that [Formula: see text] is an accurate code and we provide further benchmarking data to demonstrate this point. PMID- 29192607 TI - Modelling the impact of altered axonal morphometry on the response of regenerative nervous tissue to electrical stimulation through macro-sieve electrodes. AB - OBJECTIVE: Regenerated peripheral nervous tissue possesses different morphometric properties compared to undisrupted nerve. It is poorly understood how these morphometric differences alter the response of the regenerated nerve to electrical stimulation. In this work, we use computational modeling to explore the electrophysiological response of regenerated and undisrupted nerve axons to electrical stimulation delivered by macro-sieve electrodes (MSEs). APPROACH: A 3D finite element model of a peripheral nerve segment populated with mammalian myelinated axons and implanted with a macro-sieve electrode has been developed. Fiber diameters and morphometric characteristics representative of undisrupted or regenerated peripheral nervous tissue were assigned to core conductor models to simulate the two tissue types. Simulations were carried out to quantify differences in thresholds and chronaxie between undisrupted and regenerated fiber populations. The model was also used to determine the influence of axonal caliber on recruitment thresholds for the two tissue types. Model accuracy was assessed through comparisons with in vivo recruitment data from chronically implanted MSEs. MAIN RESULTS: Recruitment thresholds of individual regenerated fibers with diameters >2 um were found to be lower compared to same caliber undisrupted fibers at electrode to fiber distances of less than about 90-140 um but roughly equal or higher for larger distances. Caliber redistributions observed in regenerated nerve resulted in an overall increase in average recruitment thresholds and chronaxie during whole nerve stimulation. Modeling results also suggest that large diameter undisrupted fibers located close to a longitudinally restricted current source such as the MSE have higher average recruitment thresholds compared to small diameter fibers. In contrast, large diameter regenerated nerve fibers located in close proximity of MSE sites have, on average, lower recruitment thresholds compared to small fibers. Utilizing regenerated fiber morphometry and caliber distributions resulted in accurate predictions of in vivo recruitment data. SIGNIFICANCE: Our work uses computational modeling to show how morphometric differences between regenerated and undisrupted tissue results in recruitment threshold discrepancies, quantifies these differences, and illustrates how large undisrupted nerve fibers close to longitudinally restricted current sources have higher recruitment thresholds compared to adjacently positioned smaller fibers while the opposite is true for large regenerated fibers. PMID- 29192608 TI - Focus on 2D materials beyond graphene. PMID- 29192609 TI - Superior arm-movement decoding from cortex with a new, unsupervised-learning algorithm. AB - OBJECTIVE: The aim of this work is to improve the state of the art for motor control with a brain-machine interface (BMI). BMIs use neurological recording devices and decoding algorithms to transform brain activity directly into real time control of a machine, archetypically a robotic arm or a cursor. The standard procedure treats neural activity-vectors of spike counts in small temporal windows-as noisy observations of the kinematic state (position, velocity, acceleration) of the fingertip. Inferring the state from the observations then takes the form of a dynamical filter, typically some variant on Kalman's (KF). The KF, however, although fairly robust in practice, is optimal only when the relationships between variables are linear and the noise is Gaussian, conditions usually violated in practice. APPROACH: To overcome these limitations we introduce a new filter, the 'recurrent exponential-family harmonium' (rEFH), that models the spike counts explicitly as Poisson-distributed, and allows for arbitrary nonlinear dynamics and observation models. Furthermore, the model underlying the filter is acquired through unsupervised learning, which allows temporal correlations in spike counts to be explained by latent dynamics that do not necessarily correspond to the kinematic state of the fingertip. MAIN RESULTS: We test the rEFH on offline reconstruction of the kinematics of reaches in the plane. The rEFH outperforms the standard, as well as three other state-of-the art, decoders, across three monkeys, two different tasks, most kinematic variables, and a range of bin widths, amounts of training data, and numbers of neurons. SIGNIFICANCE: Our algorithm establishes a new state of the art for offline decoding of reaches-in particular, for fingertip velocities, the variable used for control in most online decoders. PMID- 29192610 TI - Comment on 'egs_brachy: a versatile and fast Monte Carlo code for brachytherapy'. AB - In a recent paper (Chamberland et al 2016 Phys. Med. Biol. 61 8214) develop a new Monte Carlo code called egs_brachy for brachytherapy treatments. It is based on EGSnrc, and written in the C++ programming language. In order to benchmark the egs_brachy code, the authors use it in various test case scenarios in which complex geometry conditions exist. Another EGSnrc based brachytherapy dose calculation engine, BrachyDose, is used for dose comparisons. The authors fail to prove that egs_brachy can produce reasonable dose values for brachytherapy sources in a given medium. The dose comparisons in the paper are erroneous and misleading. egs_brachy should not be used in any further research studies unless and until all the potential bugs are fixed in the code. PMID- 29192611 TI - Quantifying the radiant exposure and effective dose in patients treated for actinic keratoses with topical photodynamic therapy using daylight and LED white light. AB - Daylight photodynamic therapy (dl-PDT) is as effective as conventional PDT (c PDT) for treating actinic keratoses but has the advantage of reducing patient discomfort significantly. Topical dl-PDT and white light-PDT (wl-PDT) differ from c-PDT by way of light sources and methodology. We measured the variables associated with light dose delivery to skin surface and influence of geometry using a radiometer, a spectral radiometer and an illuminance meter. The associated errors of the measurement methods were assessed. The spectral and spatial distribution of the radiant energy from the LED white light source was evaluated in order to define the maximum treatment area, setup and treatment protocol for wl-PDT. We compared the data with two red LED light sources we use for c-PDT. The calculated effective light dose is the product of the normalised absorption spectrum of the photosensitizer, protoporphyrin IX (PpIX), the irradiance spectrum and the treatment time. The effective light dose from daylight ranged from 3 +/- 0.4 to 44 +/- 6 J cm-2due to varying weather conditions. The effective light dose for wl-PDT was reproducible for treatments but it varied across the treatment area between 4 +/- 0.1 J cm-2 at the edge and 9 +/- 0.1 J cm-2 centrally. The effective light dose for the red waveband (615-645 nm) was 0.42 +/- 0.05 J cm-2 on a clear day, 0.05 +/- 0.01 J cm-2 on an overcast day and 0.9 +/- 0.01 J cm-2 using the white light. This compares with 0.95 +/- 0.01 and 0.84 +/- 0.01 J cm-2 for c-PDT devices. Estimated errors associated with indirect determination of daylight effective light dose were very significant, particularly for effective light doses less than 5 J cm-2 (up to 83% for irradiance calculations). The primary source of error is in establishment of the relationship between irradiance or illuminance and effective dose. Use of the O'Mahoney model is recommended using a calibrated logging illuminance meter with the detector in the plane of the treatment area. PMID- 29192613 TI - A Health-Based Metric for Evaluating the Effectiveness of Noise Barrier Mitigation Associated With Transport Infrastructure Noise. AB - INTRODUCTION: This study examines the use of the number of night-time sleep disturbances as a health-based metric to assess the cost effectiveness of rail noise mitigation strategies for situations, wherein high-intensity noises dominate such as freight train pass-bys and wheel squeal. MATERIALS AND METHODS: Twenty residential properties adjacent to the existing and proposed rail tracks in a noise catchment area of the Epping to Thornleigh Third Track project were used as a case study. Awakening probabilities were calculated for individual's awakening 1, 3 and 5 times a night when subjected to 10 independent freight train pass-by noise events using internal maximum sound pressure levels (LAFmax). RESULTS: Awakenings were predicted using a random intercept multivariate logistic regression model. With source mitigation in place, the majority of the residents were still predicted to be awoken at least once per night (median 88.0%), although substantial reductions in the median probabilities of awakening three and five times per night from 50.9 to 29.4% and 9.2 to 2.7%, respectively, were predicted. This resulted in a cost-effective estimate of 7.6-8.8 less people being awoken at least three times per night per A$1 million spent on noise barriers. CONCLUSION: The study demonstrates that an easily understood metric can be readily used to assist making decisions related to noise mitigation for large scale transport projects. PMID- 29192612 TI - Aviation Noise Impacts: State of the Science. AB - Noise is defined as "unwanted sound." Aircraft noise is one, if not the most detrimental environmental effect of aviation. It can cause community annoyance, disrupt sleep, adversely affect academic performance of children, and could increase the risk for cardiovascular disease of people living in the vicinity of airports. In some airports, noise constrains air traffic growth. This consensus paper was prepared by the Impacts of Science Group of the Committee for Aviation Environmental Protection of the International Civil Aviation Organization and summarizes the state of the science of noise effects research in the areas of noise measurement and prediction, community annoyance, children's learning, sleep disturbance, and health. It also briefly discusses civilian supersonic aircraft as a future source of aviation noise. PMID- 29192614 TI - Using Smart Devices to Measure Intermittent Noise in the Workplace. AB - PURPOSE: To determine the accuracy of smart devices (iPods) to measure intermittent noise and integrate a noise dose in the workplace. MATERIALS AND METHODS: In experiment 1, four iPods were each paired with a Larson Davis Spark dosimeter and exposed to randomly fluctuating pink noise in a reverberant sound chamber. Descriptive statistics and the mean difference between the iPod and its paired dosimeter were calculated for the 1-s data logged measurements. The calculated time weighted average (TWA) was also compared between the devices. In experiment 2, 15 maintenance workers and 14 office workers wore an iPod and dosimeter during their work-shift for a maximum of five workdays. A mixed effects linear regression model was used to control for repeated measures and to determine the effect of the device type on the projected 8-h TWA. RESULTS: In experiment 1, a total of 315,306 1-s data logged measurements were made. The interquartile range of the mean difference fell within +/-2.0 A-weighted decibels (dBA), which is the standard used by the American National Standards Institute to classify a type 2 sound level meter. The mean difference of the calculated TWA was within +/-0.5 dBA except for one outlier. In experiment 2, the results of the mixed effects model found that, on average, iPods measured an 8-h TWA 1.7 dBA higher than their paired dosimeters. CONCLUSION: This study shows that iPods have the ability to make reasonably accurate noise measurements in the workplace, but they are not as accurate as traditional noise dosimeters. PMID- 29192615 TI - Effects of Soundscape on the Environmental Restoration in Urban Natural Environments. AB - CONTEXT: According to the attention restoration theory, directed attention is a limited physiological resource and is susceptible to fatigue by overuse. Natural environments are a healthy resource, which allows and promotes the restoration of individuals within it from their state of directed attention fatigue. This process is called the environmental restoration on individuals, and it is affected both positively and negatively by environmental factors. AIMS: By considering the relationship among the three components of soundscape, that is, people, sound and the environment, this study aims to explore the effects of soundscape on the environmental restoration in urban natural environments. MATERIALS AND METHODS: A field experiment was conducted with 70 participants (four groups) in an urban natural environment (Shenyang, China). Directed attention was first depleted with a 50-min 'consumption' phase, followed by a baseline measurement of attention level. Three groups then engaged in 40 min of restoration in the respective environments with similar visual surroundings but with different sounds present, after which attention levels were re-tested. The fourth group did not undergo restoration and was immediately re-tested. The difference between the two test scores, corrected for the practice effect, represents the attention restoration of individuals exposed to the respective environments. STATISTICAL ANALYSIS USED: An analysis of variance was performed, demonstrating that the differences between the mean values for each group were statistically significant [sig. = 0.027 (<0.050)]. RESULTS: The results showed that the mean values (confidence interval of 95%) of each group are as follows: 'natural sounds group' (8.4), 'traffic sounds group' (2.4) and 'machine sounds group' (-1.8). CONCLUSION: It can be concluded that (1) urban natural environments, with natural sounds, have a positive effect on the restoration of an individuals' attention and (2) the presence of different types of sounds has significantly divergent effects on the environmental restoration. PMID- 29192616 TI - Assessment of Reduced Tolerance to Sound (Hyperacusis) in University Students. AB - INTRODUCTION: Hyperacusis is defined as a reduction in tolerance to ordinary environmental sounds. Hyperacusis can occur in individuals of all age groups, making daily life difficult for the sufferers. Although there is no objective test to accurately diagnose hyperacusis, questionnaires are useful for the assessment of hyperacusis. The aim of this study was to explore the reduced sound tolerance in university students using a hyperacusis questionnaire (HQ). MATERIALS AND METHODS: A total of 536 university students (300 females and 236 males) aged between 18 and 25 years, with a mean age of 21.34 +/- 1.87 years, were assessed using an HQ developed by Khalfa. The mean total score of all the participants was 16.34 +/- 7.91, and 5.78% of the participants had total scores indicating hyperacusis, where a majority of them were females. RESULTS: Females had significantly higher scores than men in terms of both the total and the attentional and emotional dimensions. The scores of the participants who reported noise exposure or a decrease in their tolerance to noise were significantly higher than those of the other participants. Even among young adults, there was a group of participants suffering from some problems related to decreased tolerance to everyday sounds. DISCUSSION: Although the Turkish translation of the HQ seems to be a reliable tool for evaluating hyperacusis in young adults, further work with various populations of different age groups is required to establish validity and to assess the psychometric qualities of the Turkish form. PMID- 29192617 TI - The Effects of Low-Frequency Noise on Rats: Evidence of Chromosomal Aberrations in the Bone Marrow Cells and the Release of Low-Molecular-Weight DNA in the Blood Plasma. AB - OBJECTIVES: Evaluation of the effect of low-frequency noise (LFN) on the frequency of chromosomal aberrations in the bone marrow cells and on the content of low-molecular-weight DNA (lmwDNA) in the blood plasma of rats. MATERIALS AND METHODS: A total of 96 male Wistar rats were exposed to either single (17 min session) or multiple (17 min session repeated five times a week for 13 weeks) LFN, with the maximum range below 250 Hz and the sound pressure levels (SPLs) at 120 and 150 dB, respectively. The rats in the control groups were not subjected to any impact. The frequency of chromosomal aberrations in the bone marrow cells and the levels of lmwDNA in the blood plasma were measured afterwards. RESULTS: It has been detected that a single LFN exposure with either corresponding SPLs had a significant increase in the frequency of chromosomal aberrations (more than 10-fold) compared to the controls (0.9 +/- 0.3%) and resulted in the appearance of dicentric chromosomes in the aberration spectrum, both of which are evident for the occurrence of deoxyribonucleic acid double strand breaks triggered by the exposure. Furthermore, the lmwDNA levels in the blood plasma measured the following day after a single LFN exposure were significantly higher (7.7- and 7.6 fold, respectively) than that in the control group (11.0 +/- 5.4 ng/ml), and such levels were maintained higher (4.8- and 2.1-fold, respectively) in the week after a single LFN exposure for the SPL of 120 and 150 dB, respectively, compared to the control group (18.8 +/- 1.6 ng/ml). Similar results were obtained from the group with multiple LFN exposures (36.4- and 22.4-fold, respectively) compared to the control (17.7 +/- 1.7 ng/ml) and suggest the enhancement of cellular apoptosis as a result of the LFN impact. CONCLUSION: Presumably, the LFN may have possible mutagenic effects and cause massive cell death. PMID- 29192619 TI - Tinnitus, Medial Olivocochlear System, and Music Exposure in Adolescents. AB - INTRODUCTION: The most common cause of tinnitus is the exposure to noise; in the case of adolescents, music is the main sound source they are exposed to. Currently, one of the hypotheses about the genesis of tinnitus is related to the deterioration in the functioning of the medial olivocochlear system (MOCS). AIM: The aim of this study was to determine the presence or absence of tinnitus in adolescents with normal hearing and to relate it to: (a) the functioning of the MOCS, by the contralateral suppression of the transient evoked otoacoustic emissions (TEOAEs) and (b) the musical general exposure (MGE). MATERIALS AND METHODS: A cross-sectional descriptive correlational study was conducted. The sample was composed by adolescents with ages between 14 and 15. Two questionnaires were administered, one in relation to the subjective report of tinnitus and the other in relation to recreational activities to know the MGE. RESULTS: The results showed that the amplitude of frequencies (1000, 1500, 2000, and 3000 Hz) and global amplitude of TEOAEs, with and without acoustic contralateral stimulation, were higher in the group without tinnitus, with a statistically significant difference (P < 0.05). The suppressive effect was higher in the group without tinnitus; however, there was no statistically significant difference. Contrastingly, a significant association (P < 0.05) between exposure to music and tinnitus was observed; 72.41% of the adolescents with high exposure to music had tinnitus. DISCUSSION AND CONCLUSION: The results of the present investigation provide a contribution to the hypothesis of "the participation of the MOCS." Furthermore, a high MGE can be considered a risk factor for the onset of tinnitus. PMID- 29192618 TI - How Children Perceive the Acoustic Environment of Their School. AB - OBJECTIVE: Children's own ratings and opinions on their schools sound environments add important information on noise sources. They can also provide information on how to further improve and optimize children's learning situation in their classrooms. This study reports on the Swedish translation and application of an evidence-based questionnaire that measures how children perceive the acoustic environment of their school. STUDY DESIGN: The Swedish version was made using a back-to-back translation. Responses on the questionnaire along with demographic data were collected for 149 children aged 9-13 years of age. RESULTS: The Swedish translation of the questionnaire can be reduced from 93 to 27 items. The 27 items were distributed over five separate factors measuring different underlying constructs with high internal consistency and high inter item correlations. The responses demonstrated that the dining hall/canteen and the corridors are the school spaces with the poorest listening conditions. The highest annoyance was reported for tests and reading; next, student-generated sounds occur more frequently within the classroom than any sudden unexpected sounds, and finally, road traffic noise and teachers in adjoining classrooms are the most frequently occurring sounds from outside the classroom. Several demographic characteristics could be used to predict the outcome on these factors. CONCLUSION: The findings suggest that crowded spaces are most challenging; the children themselves generate most of the noise inside the classroom, but it is also common to hear road traffic noise and teachers in adjoining classrooms. The extent of annoyance that noise causes depends on the task but seems most detrimental in tasks, wherein the demands of verbal processing are higher. Finally, children with special support seem to report that they are more susceptible to noise than the typical child. PMID- 29192620 TI - Noise-Induced Hearing Loss - A Preventable Disease? Results of a 10-Year Longitudinal Study of Workers Exposed to Occupational Noise. AB - AIMS: To survey current, Danish industrial noise levels and the use of hearing protection devices (HPD) over a 10-year period and to characterise the association between occupational noise and hearing threshold shift in the same period. Furthermore, the risk of hearing loss among the baseline and the follow up populations according to first year of occupational noise exposure is evaluated. MATERIALS AND METHODS: In 2001-2003, we conducted a baseline survey of noise- and hearing-related disorders in 11 industries with suspected high noise levels. In 2009-2010, we were able to follow up on 271 out of the 554 baseline workers (49%). Mean noise levels per industry and self-reported HPD use are described at baseline and follow-up. The association between cumulative occupational noise exposure and hearing threshold shift over the 10-year period was assessed using linear regression, and the risk of hearing loss according to year of first occupational noise exposure was evaluated with logistic regression. RESULTS: Over the 10-year period, mean noise levels declined from 83.9 dB(A) to 82.8 dB(A), and for workers exposed >85 dB(A), the use of HPD increased from 70.1 to 76.1%. We found a weak, statistically insignificant, inverse association between higher ambient cumulative noise exposure and poorer hearing (-0.10 dB hearing threshold shift per dB-year (95% confidence interval (CI): -0.36; 0.16)). The risk of hearing loss seemed to increase with earlier first year of noise exposure, but odds ratios were only statistically significant among baseline participants with first exposure before the 1980s (odds ratio: 1.90, 95% CI: 1.11; 3.22). CONCLUSIONS: We observed declining industrial noise levels, increased use of HPD and no significant impact on hearing thresholds from current ambient industrial noise levels, which indicated a successful implementation of Danish hearing conservation programs.

PMID- 29192622 TI - Subdural empyema: Clinical presentations and management options for an uncommon neurosurgical emergency in a developing country. AB - BACKGROUND: Controversy regarding the best management strategy for subdural empyema (SDE) attests to the persisting poor outcomes for this uncommon life threatening intracranial suppurative process. Late presentation confounds the problem in developed countries. While craniotomy is commonly recommended, it is not always possible in late presentation with advanced morbidity. The aim of this study was to identify the pattern of clinical presentation and explore the outcomes following management of SDE using burr hole, aspiration, and drainage (BAAD) in resource poor settings. MATERIALS AND METHODS: This is a retrospective review of prospectively collected data of 18 patients presenting with SDE over a period of 10 years from two neurosurgical centers. Data was abstracted on patients' demographic characteristics, sources of SDE, clinical presentation and site of infection, methods of diagnosis, organisms isolated, treatments received, and outcome. Collected data was entered into the Statistical Package for the Social Sciences version 17 software and subjected to descriptive analysis for all variables. RESULTS: Majority of the patients presented late with Glasgow Coma Scale score GCS of 9/15. Altered sensorium was noted in 14 (77.8%) of the patients, 11 (61.1%) out of the 14 patients had <= grade 3 of Bannister and Williams level of consciousness. The mainstay of treatment for all patients was BAAD of abscess and administration of appropriate antibiotics. Fourteen patients (77.8%) were discharged on grade A of H.W. Mauser's grading system. Three mortalities were recorded only in patients who had grade 4 Bannister and Williams grading. CONCLUSION: BAAD is the near approximated option to standard craniotomy management in a limited resource facility and it has a very good clinical outcome. However, more studies are required to draw the final conclusion. PMID- 29192623 TI - Color recovery effect of different bleaching systems on a discolored composite resin. AB - BACKGROUND AND PURPOSE: Discoloration of resin-based composites is a commonly encountered problem, and bleaching agents may be used for the therapy of the existing discoloration. The purpose of this study was to investigate in vitro color recovery effect of different bleaching systems on the heavily discolored composite resin. MATERIALS AND METHODS: Fifty disk-shaped dental composite specimens were prepared using A2 shade nanohybrid universal composite resin (3M ESPE Filtek Z550, St. Paul, MN, USA). Composite samples were immersed in coffee and turnip juice for 1 week in each. One laser activated bleaching (LB) (Biolase Laserwhite*20) and three conventional bleaching systems (Ultradent Opalescence Boost 40% (OB), Ultradent Opalescence PF 15% home bleaching (HB), Crest 3D White [Whitening Mouthwash]) were tested in this study. Distilled water was used as control group. The color of the samples were measured using a spectrophotometer (VITA Easy shade Compact, VITA Zahnfabrik, Bad Sackingen, Germany). Color changes (DeltaE00) were calculated using the CIEDE2000 formula. Statistical analyses were conducted using paired samples test, one-way analysis of variance, and Tukey's multiple comparison tests (alpha = 0.05). RESULTS: The staining beverages caused perceptible discoloration (DeltaE00 > 2.25). The color recovery effect of all bleaching systems was statistically determined to be more effective than the control group (P < 0.05). Although OB group was found as the most effective bleaching system, there was no statistically significant difference among HB, OB, and LB groups (P > 0.05). CONCLUSION: Within the limitation of this in vitro study, the highest recovery effect was determined in office bleaching system among all bleaching systems. However, home and laser bleaching systems were determined as effective as office bleaching system. PMID- 29192624 TI - Role of trichloroacetic acid and gelfoam in closure of tympanic membrane perforations. AB - OBJECTIVE: The aim of the study was to study the closure of dry central type of tympanic membrane perforations by chemical cautery and improvement of hearing, to analyse the effect of Gelfoam on nonhealing small tympanic membrane perforations, and to examine the relevance of conservative means of closure of tympanic membrane perforations as an office procedure. MATERIALS AND METHODS: In this study, 100 patients attending the outpatient department were enrolled. Cautery of perforation margin was carried out with 50% trichloroacetic acid (TCA). After cautery, in small perforations less than 4 mm, a small piece of Gelfoam larger than the size of perforation was cut, impregnated with corticosteroid ointment, and carefully placed over the cauterized area under endoscopic visualization. In slightly larger perforations, that is, between 4 and 5 mm, after applying TCA to the margins of the perforation, a piece of Gelfoam larger than the size of perforation was soaked with corticosteroid ointment and placed in the middle ear cavity. RESULTS: Patients had relief from various symptoms, such as tinnitus, heaviness, and so on. There was some amount of auditory improvement in almost all the cases. It ranged from 5 to 23 dB. CONCLUSIONS: Cautery and patching of tympanic membrane perforation may be considered as the first-line management in the small- to medium-sized perforations before attempting the surgical closure. PMID- 29192625 TI - The force required to fracture endodontically roots restored with various materials as intra-orifice barriers. AB - OBJECTIVE: To evaluate the effect of various materials as intra-orifice barriers on the force required fracture roots. MATERIALS AND METHODS: One hundred-thirty five mandibular premolars were decoronated and prepared up to size #40. The root canals were filled and randomly divided into two control and seven experimental groups (n = 15), as follows: Positive control group (the intra-orifice barrier cavity was not prepared), negative control group (the intra-orifice barrier cavity was prepared, but not filled), filling using glass ionomer cement, nano hybrid composite resin, short fiber-reinforced composite, bulk-fill flowable composite, MTA Angelus, Micro Mega MTA or Biodentine. A fracture strength test was performed, and the data were analyzed using one-way ANOVA and Tukey's post hoc tests. RESULTS: Nano-hybrid composite, short fiber-reinforced composite, bulk fill flow able composite, and glass ionomer cement increased the force required fracture the roots compared to the positive and negative control groups (P < 0.05). While MTA groups did not increase the force required fracture the roots compared to the control groups, Biodentine increased significantly. CONCLUSIONS: Within the limitations of the present study, the use of nano-hybrid composite, short fiber-reinforced composite, bulk-fill flowable composite, and glass ionomer cement as an intra-orifice barrier may be useful in reinforcing roots. MTA placement (MTA Angelus or Micro Mega MTA) did not significantly increase the fracture resistance of endodontically treated roots compared to the control groups, however Biodentine did. PMID- 29192626 TI - Neutrophil lymphocyte ratio predicts postoperative pain after orthognathic surgery. AB - BACKGROUND AND AIM: Postoperative pain is well known and usually disturbing complication of surgery. Inflammation plays an important role in the development and progression of postoperative pain. We aimed to investigate possible relationship between preoperatively measured neutrophil-lymphocyte ratio (NLR) - as an inflammation marker - and postoperative analgesic demand in patients underwent orthognathic surgery. MATERIALS AND METHODS: We retrospectively investigated medical and anesthesia records of 177 patients underwent orthognathic surgery. Demographical data, preoperative NLR, type of surgery, modified Mallampati score, difficulty degree of intubation, duration of surgery, and postoperative analgesic (tenoxicam - as the first drug of choice, paracetamol, tramadol, or pethidine) usage were recorded. A cutoff value of NLR >=2 was determined for inflammation threshold. Two groups (Group 1 NLR >=2, Group 2 NLR <2) were compared for analgesic doses, numbers of patients needed analgesic treatment, and other parameters. RESULTS: Mean administered tenoxicam dose was significantly higher in Group 1 than in Group 2 (P < 0.0001). Further, ratio of patients treated with tenoxicam in Group 1 was significantly higher than that in Group 2 (chi2 = 4.779, P = 0.029). CONCLUSIONS: Preoperatively measured NLR may help to predict postoperative analgesic demand in patients undergoing orthognathic surgery, and thus sufficient postoperative pain control can be achieved with various preventive treatments taken at the perioperative period such as preemptive analgesia, local anesthetic administration at the end of surgery, or early administration of analgesics. PMID- 29192627 TI - Behavioural and anthropometric risk factors for diabetes mellitus among newly admitted undergraduates in a Nigerian University. AB - BACKGROUND: Type 2 diabetes mellitus (DM) is fast becoming a global epidemic, and its prevalence is increasing in children and young adults. The aim of the study was to identify young adults who had type 2 DM or impaired fasting glucose as well as those at risk of these conditions using anthropometric data and behavioral pattern. METHODOLOGY: Two hundred and twenty newly admitted undergraduates who were randomly selected during the registration process were involved in the study. Anthropometric parameters were measured while information on demographic details, medical history, and family history were obtained using a standard questionnaire. Fasting blood glucose was measured using the glucose oxidase method. RESULTS: Two hundred and seven (94%) participants had serum glucose within reference range, 10 (4.6%) had impaired fasting glucose, and 3 (1.4%) had serum glucose> 7.1 mmol/L, which is indicative of DM. A large number (91.4%) of individuals engaged in physical activity equivalent to a walk of at least 30 min/day. Most of them (93.2%) had body mass index <25.0 while 6.8% were overweight. One hundred and three participants (46.8%) indicated that they eat 3 or more servings of whole grain per day. CONCLUSION: Most of the participants are involved in healthy lifestyle. This has resulted in very low prevalence of impaired fasting glucose and type 2 DM among the group. It will be useful to follow up the group and note if they are able to maintain this trend since the risk of developing DM is known to increase with age. PMID- 29192628 TI - A comparative study of the oral microbiome compositions of healthy postmenopausal, premenopausal, and prepubertal Nigerian females, using 16s rrna metagenomics methods. AB - INTRODUCTION: There is a paucity of information on the oral microbiome compositions of Nigerians, mostly due to lack of appropriate molecular techniques. In this pilot study, we sought to determine and characterize the oral bacterial compositions of "healthy" females. MATERIALS AND METHODS: Oral samples were collected from three randomly selected females aged 56, 28, and 8 years. DNA was extracted and 16S rRNA V4 region was amplified using custom-barcoded primers before sequencing with Illumina MiSeq platform. Quantitative Insights into Microbial Ecology pipeline was used for 16S rRNA recognition. Distribution of taxonomic categories at different levels of resolution was done using the ribosomal RNA similarities to entries in the REFseq protein database. Diversity score was calculated based on the inverse Simpson's index. RESULTS: The inverse Simpson's diversity index for the postmenopausal, premenopausal, and prepubertal was 7.74, 6.95, and 7.42 respectively. A total of 12 phyla, 70 genera, and 85 species were detected. Firmicutes followed by Proteobacteria, Actinobacteria, Bacteroidetes, and Fusobacteria dominated the oral microbiome of the subjects. Streptococcus thermophilus (33.19%) was the most abundance species in subject 1, while subject 2 was highly predominated by Haemophilus parainfluenzae (80.65%), and subject 3 was predominated by Haemophilus influenzae (23.05%). CONCLUSION: The study has revealed that bacteria with varying diversities colonized the subjects and it highlighted the importance of metagenomics in deciphering the oral bacterial compositions from females of different age groups. More studies are needed using metagenomics approach, to appreciate these bacterial organisms that are associated with health and disease in our environment. PMID- 29192629 TI - Prevalence of traumatic dental injuries and associated factors among 8 to 12 years-old schoolchildren in Diyarbakir, Turkey. AB - BACKGROUND AND OBJECTIVES: This study aimed to assess the prevalence of traumatic injuries of the permanent incisors in public primary schoolchildren from 8 to 12 years old in South-Eastern Anatolia, Turkey. Additionally, the relationship between traumatic dental injuries, parents' education level, family income, size of incisal overjet and the presence of anterior open bite were examined. MATERIALS AND METHODS: Data were collected through oral examinations and structured interviews, and included socio-economic indicators. A total of 2907 children of both genders (1498 boys, 1409 girls) were included in the study. The response rate was 97%. RESULTS: The prevalence of dental injuries was 4.6% (n = 135). The highest frequency of trauma in permanent teeth was observed at the age of 12 (8%). Boys experienced more dental injuries than girls, 5.9% and 3.3% (p = 0.001), respectively. The most commonly reported cause of injuries to the permanent incisors was falls (71.8%), followed by collision with objects or people (17.8%). Maxillary central incisors were the most affected by dental injuries (154, 84.6%). The most common crown fracture was in enamel only (67.58%) followed by crown fracture of enamel and dentin (22.52%). CONCLUSION: Socio economic indicators and parents' level of education were not statistically significantly associated with the occurrence of traumatic dental injuries. Factors associated with increased risk of dental injuries in permanent teeth were age, gender, having an incisal overjet greater than 5mm and anterior open bite. PMID- 29192630 TI - Diagnostic utility of alpha-fetoprotein and des-gamma-carboxyprothrombin in nigerians with hepatocellular carcinoma. AB - BACKGROUND: Alpha-fetoprotein (AFP) and Des-gamma-carboxyprothrombin (DCP) have been extensively studied as biomarkers for the diagnosis of and prognostication in hepatocellular carcinoma (HCC). However there are only few reports on the clinical characteristics of hepatocellular carcinoma in relation to the combination of the two tumor markers in hepatitis B virus-related HCC. AIM: The aim of this study was to investigate the clinical characteristics of HBV-related HCC in relation to different sets of AFP and DCP values. METHODS: Sixty-two patients with untreated HCC were studied. The positive value of AFP was set at 20 1U/L while DCP positive value was set at 150 mAU/ml. Patients were divided into three groups: Group 1(n=36) with AFP >= 20 IU/L and DCP >= 150 mAU/ml. Group 2(n=24) with AFP <20 1U/L and DCP >= 150 mAU/ml. Group 3 (n=2) with AFP < 20 1U/L and DCP < 150 mAU/ml. There were no patients in group 4 meant for those with AFP >= 20 1U/L and DCP < 150 mAU/ml. Clinical and laboratory variables were compared among the groups. RESULTS: Clinical and laboratory variables were comparable among the groups with the exception of gender and values of serum alanine aminotransferase (ALT). Males were significantly more than females among the groups (p<0.03). ALT values were significantly different among the groups (p<0.006). Paired comparisons between the groups showed the mean values of serum ALT were significantly higher in group 2 than in group 1(p<0.003). The mean serum ALT values were also higher in group 2 than in group 3 (p <0.014). There was no significant difference between group 1 and group 3 (P = 0.124). CONCLUSION: HCC patients who are sero-positive for DCP and sero-negative for AFP have significantly higher levels of serum ALT; serum ALT levels may be of diagnostic importance in AFP-negative, HBV-related HCC patients. PMID- 29192631 TI - Intermittent testicular torsion. AB - OBJECTIVE: The aim of this study is to highlight the clinical characteristics of patients with intermittent testicular torsion and draw attention to this underreported condition. METHODS: Clinical and demographic data of all patients treated for intermittent testicular torsion from January 2007 to June 2015 were prospectively collected in a pro forma and analyzed. A diagnosis of intermittent torsion was made on the basis of recurrent scrotal pain, presence of abnormal testicular lie in otherwise normal testes, absence of urinary symptoms, and negative urine cultures. This diagnosis was confirmed by resolution of symptoms following bilateral orchidopexy. All patients had bilateral orchidopexy at the next operative day and were followed up for 12 months. RESULTS: Forty-five patients with a mean age of 20.9 years (+/-4.02) were seen within the study period. The left testis was more often involved than the right: 53.3% versus 37.8%. The condition was bilateral in 4 patients (8.9%). A total of 84 testes were evaluated. Horizontal lie was the most common anomaly causing intermittent testicular torsion 49%, followed by the clapper-bell deformity 27.5%. Patients experienced a mean of 2.8 (+/-1.74) acute pain episodes before testicular fixation. Bilateral orchidopexy resulted in resolution of symptoms and preservation of testicular volume. CONCLUSION: Horizontal lie of the testis is the most common cause of intermittent testicular torsion. The condition is more common on the left than the right testis and is predominantly unilateral. Intermittent testicular pain in the presence of abnormal testicular lie should warrant a diagnosis of intermittent testicular torsion. Early bilateral orchidopexy is efficacious. PMID- 29192632 TI - Effect of different modes of erbium:yttrium aluminum garnet laser on shear bond strength to dentin. AB - OBJECTIVES: The aim of this study was to evaluate the effect of different surface treatments on the shear bond strength (SBS) of resin composites to dentin using total etch dentin bonding adhesives. MATERIALS AND METHODS: Sixty extracted human molars were flattened to obtain dentin surfaces. The samples were divided into three groups (n = 20): Group I: 37% phosphoric acid + optibond FL + resin composite; Group II: Erbium:yttrium aluminum garnet (Er:YAG) laser (medium short pulse [MSP] mode, 120 mJ/10 Hz) + optibond FL + resin composite; Group III: Er:YAG laser (quantum square pulse [QSP] mode, 120 mJ/10 Hz) + optibond FL + resin composite. After the specimens were prepared, the SBS test was performed at a crosshead speed of 0.5 mm/min. The fractured specimens were examined under a stereomicroscope to evaluate the fracture pattern. Statistical analyses were performed with one-way ANOVA and Tukey's honestly significant difference tests. One sample of treated dentin surface from each group was sputter-coated with gold, and scanning electron microscope (SEM) images were captured. RESULTS: Acid etching showed significantly higher SBS than the other groups (P < 0.05). However, the difference between Er:YAG MSP and QSP mode groups was not statistically significant (P > 0.05). SEM images of the acid-etched dentin surface showed opened dentinal tubule with a regular surface, but Er:YAG MSP mode treated surface was irregular. The surface treated with Er:YAG QSP mode represented wide dentinal tubules with a clean and flat surface. CONCLUSION: Using different modes (MSP and QSP) of Er:YAG laser for dentin surface treatment before application of total etch adhesives is still not an sufficient alternative compared to acid etching. PMID- 29192633 TI - Pattern of maxillofacial surgical conditions in North Central Nigeria: A 5-year experience of an indigenous surgical mission. AB - BACKGROUND: Several publications have presented pattern of maxillofacial surgical conditions based on data from hospital-based studies. The objective of this study is to present the spectrum of maxillofacial surgical conditions from the perspective of a community study. METHODS: This is a prospective study of all patients seen and treated from 2011 to 2016. The information obtained included the biodata, clinical history of the disease conditions, radiological result, histopathologic result, diagnosis, and treatment records. Data analysis was carried out using SPSS version 20.0. RESULTS: There was a total of 863 patients, male 464 (53.8%) and female 399 (46.2%). The male to female sex ratio was 1.16:1. The age range was 3 days to 76 years with a mean age (SD) 16.8 +/- 15.8 years. The spectrum of surgical conditions: facial clefts 492(57.0%); tumor and tumor like lesions 126(15.2%), trauma 6(0.7%), and others 48(5.5 %). The size of tumors ranged from 5 to 50.4 cm2 with a mean (SD) 21.6 +/- 11.9 cm2 and the duration of lesion ranged from 1 to 20 years with mean (SD) 8.7 +/- 6.0 years. A total of 622(77.4) cases were operated within the study period with immediate jaw reconstruction in 5(0.8%) patients. Minor complications were recorded but there was no mortality. CONCLUSION: The spectrum of maxillofacial surgery from community-based data was associated with higher percentage of facial cleft as compared to hospital-based study that is associated with higher traumatic injury cases. High level of poverty, ignorance, and poor access to maxillofacial service have been identified as shortcomings in the management of the diseases. There is a need for pragmatic move to improve facility, training, enlightenment, and more funding of outreach programs. PMID- 29192634 TI - The Pattern of significant lesions found in computerized tomography scan of recurrent seizure patients at a center in Enugu, Nigeria. AB - INTRODUCTION: Seizures are common reasons for neurologic consultations and investigations. In the absence of magnetic resonance imaging, computerized tomography scanning of the brain is a reliable and cheaper alternative. Little is known about the pattern of brain lesions in patients with recurrent seizures in Nigeria. OBJECTIVES: To determine the pattern of significant intracerebral lesions in patients presenting with recurrent seizures in a tertiary hospital in Enugu. METHODS: All the medical and computer tomography records of patients with a clinical diagnosis of recurrent seizures were reviewed. The study duration was 11 years (January 2003 to December 2013). Relevant data were obtained and statistical analysis was done using SPSS version 19 and GraphPad Prism 6. RESULTS: The diagnostic yield of CT was 55.1%. Twenty (9.3%) individuals had two lesions each. The significant findings were tumors (20.4%), encephalomalacia (18.9%) and strokes (7.7% (ischemic stroke, 4.1%, intracerebral hemorrhage, 3.1%, subarachnoid hemorrhage/intraventricular hemorrhage, 0.5%). Hydrocephalus (HCP) was found in 18 (9.2%) cases, and 30% of them occurred together with other lesions. The diagnostic yield increased with age reaching 84.4% from the age of 60 years. Only patients with encephalomalacia were statistically older than those with normal imaging. CONCLUSION: Computed tomography scan has a high diagnostic yield, especially in elderly patients with recurrent generalized seizures. Brain tumors, encephalomalacia, and HCP are most common causes of recurrent seizures in the adults. PMID- 29192636 TI - Assessment of body perception, psychological distress, and subjective quality of life among obese and nonobese subjects in Turkey. AB - BACKGROUND: Obesity can lead to psychological, social, and medical problems that may negatively affect the quality of life Aim: In our study, we aimed to evaluate the body perception, psychological distress, and subjective quality of life of obese subjects in comparison with normal weighted ones. METHODS: A total of 494 subjects, aged between 18 and 64 years, were included to the study. Patients with the body mass index (BMI) of >=18.5-24.9 kg/m2 were assigned to the control group; BMI >= 30 kg/m2 were assigned to the obese patient group. An ethical committee approval with protocol No. of 2011/242 was obtained from the Ethical Committee of Eskisehir Osmangazi University Faculty of Medicine. Interviews were performed two times with obese subjects in the 1st and the 6th month of weight loss program, once with the control group. Data identification form, the form which included the biochemical parameters, Trait Anxiety inventory, State anxiety scale, Quality of Life scale-Short Form [(SF-36)(QOL)], Multidimensional Body Self Relations Questionnaire (MBSRQ), Zung Depression Rating Scale, and Zung Anxiety Rating Scale were applied to participants. RESULTS: Obesity is more common in women. Obesity reduces the quality of life, negatively affects body perception, and triggers anxiety. Because of their body structure, obese individuals are exposed to social pressure and unethical attitudes. CONCLUSIONS: Both health risks and social implications of obesity are important. Further studies are needed to ethically evaluate the psycho-social problems caused by obesity. PMID- 29192635 TI - Is hemorrhage the reason in crimean-congo hemorrhagic fever patients with neurological signs and symptomsa. AB - PURPOSE: Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease can result in mortality varying from 3.0% to 50.0%. In this study, we wished to discuss computed tomography (CT) findings together with clinical and laboratory findings in patients who had disease-related neurological signs. MATERIALS AND METHODS: The study included patients who were diagnosed with CCHF. Seventeen patients that had neurological signs were enrolled as the patient group. As a control group, 40 patients diagnosed with CCHF and did not have neurological signs were enrolled. Patients who had neurological signs were examined with brain CT. Radiological and clinical findings of both groups were compared. RESULTS: There were pathological findings in three patients while brain CT's of 14 patients were evaluated as normal. Blood urea nitrogen, lactate dehydrogenase, creatine kinase, total bilirubin, neutrophil, activated partial thromboplastin time, and C-reactive protein levels were significantly higher in the group with neurological signs whereas platelet count and calcium levels were significantly lower in this group. Six of 57 patients died during the follow-up period. Six patients who died were in the group, in which central nervous system (CNS) imaging study was performed. CONCLUSION: As the presence of CNS signs is a bad prognostic indicator in CCHF, they should be investigated carefully. PMID- 29192637 TI - Predictors of Vitamin D deficiency in predialysis patients with stage 3-5 chronic kidney diseases in Southern China. AB - OBJECTIVE: Vitamin D status and risk factors of Vitamin D deficiency in chronic kidney disease (CKD) patients in China have been seldom reported before. In this study, we aim to investigate serum 25-hydroxyvitamin D [25(OH)D] status and find the predictors of Vitamin D deficiency in predialysis patients with Stage 3-5 CKDs in Southern China. METHODS: In this retrospective cross-sectional study, hospitalized predialysis patients who were diagnosed of Stage 3-5 CKD and had taken measurement of serum 25(OH)D in a single center from January 2014 to June 2015 were included. Patients were divided into Vitamin D deficiency group and nondeficiency group depending on the cutoff serum 25(OH)D value of 37 nmol/L. Clinical and biochemical parameters were collected and evaluated for predictors of Vitamin D deficiency by logistic regression. RESULTS: One hundred and fifty two patients were included in this study, of which 87 (57.2%) were in Vitamin D insufficiency state while 60 (39.5%) were in Vitamin D deficiency state. Serum 25(OH)D levels of patients in Stage 4 and Stage 5 CKD were lower than that of patients in Stage 3 CKD (P = 0.002). It was discovered that female gender (odds ratio [OR] = 3.674; 95% confidence interval [CI], 1.607-8.396; P = 0.002), serum albumin level <30.0 g/L (OR = 6.816; 95% CI, 2.634-17.633; P < 0.001), and estimated glomerular filtration rate (eGFR) <30 ml/min/1.73 m2 (OR = 4.761; 95% CI, 1.353-16.754; P = 0.015) were independent predictors of Vitamin D deficiency. CONCLUSIONS: Vitamin D insufficiency and deficiency are common in predialysis patients with Stage 3-5 CKD in Southern China. Female gender, hypoalbuminemia with serum albumin level <30.0 g/L, and severe damaged renal function with eGFR <30 ml/min/1.73 m2 are independent predictors of Vitamin D deficiency in predialysis patients with Stage 3-5 CKD. PMID- 29192638 TI - Clinical outcomes after open locked intramedullary nailing of closed femoral shaft fractures for adult patients in a Nigerian Hospital. AB - BACKGROUND: Femoral shaft fractures are common injuries in adults. Closed locked intramedullary nailing is the recommended treatment for femoral shaft fractures due to its high union rate. OBJECTIVE: The objective of this study is to determine the outcome of management of closed femoral shaft fractures in adult patients, using open locked intramedullary nailing. PATIENTS AND METHODS: This is a prospective study which was carried out on all adult patients aged 16 years and above who presented within 2 weeks of sustaining closed femoral shaft fractures to the accident and emergency unit of a University Teaching Hospital in Nigeria from January 2013 to December 2013. Pathological fractures were excluded from the study. The procedure was carried out using standard techniques, and each patient was followed up for a minimum of 1 year. RESULTS: Forty-three patients were recruited into the study. They had a mean age of 36.9 +/- 11.7 years, with a male to female ratio of 2.9:1. The most common cause of closed femoral shaft fractures was road traffic crashes (95.3%), with motorcycle-related injuries found to be the highest type (56.1%). The rate of union in the study was 95.3%. The average time to radiological union was 14.0 +/- 1.2 weeks while the mean time to painless full weight bearing was 14.2 +/- 1.2 weeks. Among the complications encountered were broken nails (4.7%), infection, loosening of the distal screw, and limb length discrepancy (2.3% each). Using Thoresen's criteria, excellent results were obtained in 93% and poor results in 4.7% of patients. CONCLUSION: Open locked intramedullary nailing gives excellent clinical outcomes with high union and low complication rates in the management of closed femoral shaft fractures in adult patients. PMID- 29192639 TI - Intrathecal ropivacaine in cesarean delivery. AB - OBJECTIVE: The aim of the present study was to evaluate the optimum dose of ropivacaine by comparing three different dosing regimens of isobaric ropivacaine 1% (naropin 10 mg/ml, Astra Zeneca) administered intrathecally and to demonstrate the effects of anesthesia in pregnant women scheduled for cesarean section. PATIENTS AND METHODS: Sixty ASA grade I-II patients were scheduled to undergo elective cesarean sections under spinal anesthesia. The patients were randomly assigned into three groups. Group 1 received 15 mg ropivacaine 1%, Group 2 received 20 mg ropivacaine 1%, and Group 3 received 25 mg ropivacaine 1%. RESULTS: Intraoperative hemodynamic variables were not significantly different between the three groups, and sensory block time, motor block time and time to reach maximal sensory block time, and motor block time were similar between the three groups. The time to two-segment regression of sensory block was longer in Group 3 compared to other groups, and the difference was statistically significant (p < 0.05). The motor block time was longer with higher doses of ropivacaine; however, the difference was not statistically significant. CONCLUSION: Ropivacaine administration produced rapid induction of anesthesia and satisfactory anesthesia level, ropivacaine 15 mg and 20 mg dosing regimens are satisfactory for spinal anesthesia. PMID- 29192640 TI - Axial length/corneal radius of curvature ratio and refractive status in an adult Nigerian population. AB - AIM/BACKGROUND: Associations between axial length (AL) to corneal radius of curvature (CR) ratio and refractive status in a healthy Nigerian adult population were studied. MATERIALS AND METHODS: Healthy students and members of staff of Obafemi Awolowo Teaching Hospitals Complex, Ile-Ife, South West Nigeria, free of obvious ocular diseases except possible refractive errors were recruited. Consecutive consenting volunteers were recruited by simple random sampling and a proportionate sample of each population based on its representative fraction in the hospital community was recruited. The study was conducted between June and August 2011. Noncycloplegic objective refraction was done and spherical equivalent refraction (SER) of the right eyes was used for calculation. The AL, CR, and keratometric readings were measured with the IOL Master. The AL/CR ratio was calculated. The data were analyzed with statistical software package STATA 13. RESULTS: Three hundred and fifty volunteers aged 18-60 years were studied. The mean +/- standard deviation of AL/CR and SER were 3.04 +/- 0.10 and -0.38 +/- 1.42D, respectively. AL in myopia was significantly higher than in emmetropia and hypermetropia. There were no significant differences between CR in the refraction groups. Myopes had significantly higher AL/CR than nonmyopes. On controlling for age and gender, 1 mm increase in AL increased SER by -0.77D (95% confidence interval [CI] -0.91--0.64D) while a unit increase in AL/CR increased SER by 8.89D (95% CI -10.00--7.78D). Whereas AL accounts for 39% of variability in SER (P < 0.001), AL/CR accounts for 51% of the variability observed in SER (P < 0.001). CONCLUSION: This study has further confirmed that the AL remains a strong determinant of refraction, but a derived factor AL/CR accounts for more variation in final refractive status than AL in isolation.

AB - BACKGROUND: To determine an exploratory estimation of the strength of type 2 diabetes mellitus (T2DM) and hypertension diagnoses as risk indicators for missing teeth in a sample of Mexican adults. MATERIALS AND METHODS: A comparative cross-sectional study of sixty adult patients in a health center in Mexico included as dependent variable, the number of missing teeth (and having a functional dentition) and as independent variables, diagnoses for diabetes or hypertension, age, sex, maximum level of schooling, and tobacco use. Of the 60 participants, 20 were diagnosed with T2DM, 13 with hypertension, and 27 were otherwise diagnosed as healthy in their most recent medical checkup. A negative binomial regression (NBR) model was generated. RESULTS: Mean age was 50.7 +/- 16.2 and 50.0% were women. Mean number of missing teeth was 4.98 +/- 4.17. In the multivariate NBR model, we observed that individuals with T2DM had higher risk of more missing teeth (incidence rate ratios [IRRs] = 3.13; 95% confidence interval [CI] = 2.09-4.69), followed by those with hypertension (IRRs = 2.63; 95% CI = 1.77-3.90). In addition, participants with current tobacco use were significantly more likely to have suffered tooth loss (P < 0.05) than those who were never smokers or former smokers, just like older participants (P < 0.05). CONCLUSIONS: T2DM and hypertension are independently associated with higher experience of missing teeth in an open adult population in Mexico. Future studies with a more sophisticated epidemiological design and encompassing a more detailed landscape of chronic diseases, type and length of use of long-term medications, and patterns of dental care use are needed to better delineate these associations. PMID- 29192642 TI - Importance of optical diagnosis in early gastric cancer: A case report of early gastric signet ring cell carcinoma. AB - Gastric signet ring cell carcinoma (SRCC) is a rare form of highly malignant adenocarcinoma. It is an epithelial malignancy characterized by the histologic appearance of more than 50% of cells as signet ring cells filled with mucin. The incidence of SRCC is rising,[1],[2] therefore, the diagnosis of these cancers in the early stage is important as it is the only stage that curative measures can be done. A 49-year-old female was hospitalized due to epigastric pain, postprandial bloating for 3 months. Upper gastrointestinal endoscopy with narrow band imaging (NBI) showed 1.5 cm lesion in the lesser curvature of the stomach with irregular pit pattern and accentuated vascularization of the surrounding mucosa. Histopathology confirmed the presence of more than 50% of the cells as signet ring cells. We report on the importance of optical diagnosis in early gastric cancer with the help of NBI, the subsequent patient management, and prognosis. PMID- 29192643 TI - Multiple primary tumors. AB - Multiple primary tumors occur in clinical practice causing diagnostic dilemma. It is not very common, but the incidence has increased gradually since it was first described very many years ago. However, in spite of its increasing incidence, the presence of such primary malignancies in the breast and colon has been rare and far between, as against its presence in breast and lungs, both breasts, colon and stomach, two colonic sites, and endometrium and ovaries. It could be due to genetic disorders such as Li-Fraumeni syndrome in which case the affected individuals develop multiple cancers in childhood or early adulthood. This is, however, very rare. It could be due to metastasis of one cancer to another site. The challenge is making a correct diagnosis and giving the appropriate management. Erroneously handling one as a metastasis of the other and instituting management as such would be inappropriate. It is necessary to make proper clinical and histopathological diagnosis and to institute proper management. We report the case of a woman who had primary cancers involving rare organ combinations of the breast and ascending colon. PMID- 29192644 TI - Automated (Centrifugal) therapeutic plasma exchange option for guillain-barre syndrome: A report from Calabar, Nigeria. AB - Therapeutic plasma exchange (TPE) is performed frequently and effectively in developed countries, whereas the reverse is the case in developing countries. Guillain-Barre syndrome (GBS), synonymous with acute inflammatory demyelinating polyneuropathy, is an important indication for TPE, but this is rarely administered in the treatment of such patients in Nigeria due to lack of such automated facility, limited expertise, and high cost. This report therefore presents an uncommon case of GBS in which automated TPE was utilized in the management, with the aims of highlighting the current status and challenges of therapeutic apheresis services in Nigeria. A 42-year-old male presented with rapidly progressive (in an ascending fashion) paralysis of all four limbs within 24 h without any preceding history of fever or other symptoms. Clinical examination revealed a young man, afebrile, not pale, and also not dehydrated. Central nervous system examination showed a conscious man, alert, and oriented in time, person, and place. There were no signs of meningeal irritation and the cranial nerves were grossly intact. There was no power in the limbs: global hypotonia and areflexia were noted on examination. However, he had intact sensory perceptions to touch and pain. Following a diagnosis of GBS, he was treated with four sessions of plasmapheresis and TPE. The TPE session was done using a discontinuous flow apheresis machine which exchanged one plasma volume (3 L of plasma) and 5% albumin used for replacement. The patient made gradual but steady recovery as return of power to the upper limbs and trunk started by the 2nd week of treatment. TPE is an important treatment modality in the management of GBS as well as several other conditions, and it is becoming increasingly available in Nigeria. However, it is still grossly underutilized, thus the need for more therapeutic apheresis facilities and trained personnel, in addition to concerted efforts to subsidize the cost of accessing the treatment. PMID- 29192645 TI - H19 lncRNA regulates keratinocyte differentiation by targeting miR-130b-3p. AB - Aberrant differentiation of keratinocytes has been demonstrated to be associated with a number of skin diseases. A growing number of studies have showed that long noncoding RNAs (lncRNAs) have an important part in gene regulation, however, the role of lncRNAs in keratinocyte differentiation remains to be largely unknown. In the present study, we demonstrated that lncRNA-H19 act as an endogenous 'sponge', which binds directly to miR-130b-3p and therefore inhibits its activity on Dsg1. MiR-130b-3p was illustrated to inhibit keratinocyte differentiation by targeting Dsg1. H19 regulates Dsg1 expression and the consequent keratinocyte differentiation through miR-130b-3p. Our study casts light on a novel regulatory model of keratinocyte differentiation, which may provide new therapeutic targets of skin diseases. PMID- 29192646 TI - Development of a novel histologic diagnostic algorithm for hepatic graft-versus host disease. AB - The histopathologic diagnosis of hepatic graft-versus-host disease post bone marrow and stem cell transplantation can be challenging, but timely and unambiguous diagnosis is essential for appropriate patient management. To address this diagnostic dilemma, we identified histologic features specific for hepatic graft-versus-host disease and developed a diagnostic algorithm. Two hepatopathologists blindly evaluated 40 liver biopsies from patients with clinically and biologically confirmed graft-versus-host disease, as well as 44 controls, for percent bile duct loss, bile duct damage, intraepithelial lymphocytes, ductular reaction, acidophilic bodies/10 high power fields (HPF), cholestasis, portal and lobular inflammation, and endotheliitis. Compared with controls, graft-versus-host disease cases had significantly more bile duct loss (P<0.0001), bile duct damage (P=0.0002), cholestasis (P<0.0001), and acidophilic bodies/10 HPF (P=0.0006), as well as significantly less ductular reaction (P<0.0001). Significance was maintained with a drug-induced liver injury-only control group. No histologic differences were noted in acute versus chronic graft versus-host disease, nor cholestatic versus hepatitic types. An algorithm to predict likelihood of graft-versus-host disease was developed, with a three tiered scoring system: 1-2 not, 3-4 probable, and 5-8 unequivocal graft-versus host disease. This algorithm had a sensitivity of 93%, specificity of 93%, and accuracy of 92%. We identified histologic features with specificity for hepatic graft-versus-host disease and developed a simple algorithm for pathologists to predict its likelihood, distinguishing this critical diagnosis promptly from mimickers having vastly different treatments and prognoses. PMID- 29192649 TI - The histopathology of Erdheim-Chester disease: a comprehensive review of a molecularly characterized cohort. AB - Erdheim-Chester disease is a rare, non-Langerhans cell histiocytosis histologically characterized by multi-systemic proliferation of mature histiocytes in a background of inflammatory stroma. The disease can involve virtually any organ system; most commonly the bones, skin, retroperitoneum, heart, orbit, lung, and brain are affected. Although a histiocytic proliferation is the histological hallmark of the disease, a wide range of morphological appearances have been described as part of case studies or small series. A comprehensive review of histopathological features in clinically and molecularly defined Erdheim-Chester disease has yet to be characterized. To address this issue and help guide clinical practice, we comprehensively analyzed the pathological spectrum of Erdheim-Chester disease in a clinically and molecularly defined cohort. We reviewed 73 biopsies from 42 patients showing involvement by histiocytosis from a variety of organ systems, including bone (16), retroperitoneum (11), skin (19), orbit (6), brain (5), lung (6), cardiac structures (2), epidural soft tissue (3), oral cavity (2), subcutaneous soft tissue (2), and testis (2). In eight patients, one or more bone marrow biopsies were performed due to clinical indication and an accompanying myeloid neoplasm was detected in six of them. Thirty-eight cases were investigated for genetic abnormalities. Somatic mutations involving BRAF (25/38), MAP2K1 (6/38), ARAF (2/38), MAP2K2 (1/38), KRAS (1/38), and NRAS (1/38) genes were detected. One of the cases with a MAP2K1 mutation also harbored a PIK3CA mutation. We have observed marked heterogeneity in histology and immunophenotype, identified site specific features, overlap with other histiocytic and myeloid disorders and potential diagnostic pitfalls. We hope that broadening the spectrum of recognized pathologic manifestations of Erdheim-Chester disease will help practicing clinicians and pathologists to diagnose Erdheim-Chester disease early in the disease course and manage these patients effectively. PMID- 29192648 TI - Identification of clinically relevant cytomegalovirus infections in patients with inflammatory bowel disease. AB - Several lines of evidence indicate that cytomegalovirus infection can be substantially associated with onset of inflammatory bowel disease, especially in patients refractory to immunosuppressive treatment. As cytomegalovirus is widely spread in the population, here we present a quantitative detection system suitable to differentiate clinically relevant cytomegalovirus infection from common latent cytomegalovirus. Using a quantitative real-time PCR approach, cytomegalovirus viral load was evaluated in 917 formalin-fixed and paraffin embedded colon biopsy samples of 136 patients diagnosed with inflammatory bowel disease. Besides initial cytomegalovirus testing, the PCR system was also used to monitor therapy response after antiviral treatment. Cytomegalovirus DNA was detected in 37 patients (27%) with varying viral loads ranging from 5 to 8.7 * 105 copies/105 cells. Thereof, 13 patients (35%) received an antiviral treatment with 12 of them going into remission (92%). Later, five patients displayed a relapse and three patients who agreed to restart antiviral treatment again showed positive therapy response. A retrospective comparison of viral loads with antiviral therapy response revealed a threshold of 600 cytomegalovirus copies/105 cells as indicative for clinically relevant infection. Of note, sensitivity of cytomegalovirus detection by immunohistochemistry was found to be insufficient to reliably identify antiviral therapy responders. In conclusion, quantitative real time PCR using formalin-fixed biopsy samples is suitable for detection of cytomegalovirus infection in tissue samples of patients with inflammatory bowel disease. Moreover, it allows the definition of a viral load threshold, predictive for clinical relevance concerning antiviral therapy response. PMID- 29192647 TI - Implications of the tumor immune microenvironment for staging and therapeutics. AB - Characterizing the tumor immune microenvironment enables the identification of new prognostic and predictive biomarkers, the development of novel therapeutic targets and strategies, and the possibility to guide first-line treatment algorithms. Although the driving elements within the tumor microenvironment of individual primary organ sites differ, many of the salient features remain the same. The presence of a robust antitumor milieu characterized by an abundance of CD8+ cytotoxic T-cells, Th1 helper cells, and associated cytokines often indicates a degree of tumor containment by the immune system and can even lead to tumor elimination. Some of these features have been combined into an 'Immunoscore', which has been shown to complement the prognostic ability of the current TNM staging for early stage colorectal carcinomas. Features of the immune microenvironment are also potential therapeutic targets, and immune checkpoint inhibitors targeting the PD-1/PD-L1 axis are especially promising. FDA-approved indications for anti-PD-1/PD-L1 are rapidly expanding across numerous tumor types and, in certain cases, are accompanied by companion or complimentary PD-L1 immunohistochemical diagnostics. Pathologists have direct visual access to tumor tissue and in-depth knowledge of the histological variations between and within tumor types and thus are poised to drive forward our understanding of the tumor microenvironment. This review summarizes the key components of the tumor microenvironment, presents an overview of and the challenges with PD-L1 antibodies and assays, and addresses newer candidate biomarkers, such as CD8+ cell density and mutational load. Characteristics of the local immune contexture and current pathology-related practices for specific tumor types are also addressed. In the future, characterization of the host antitumor immune response using multiplexed and multimodality biomarkers may help predict which patients will respond to immune-based therapies. PMID- 29192650 TI - Intramucosal lipomas of the colon implicate Cowden syndrome. AB - Intramucosal lipomas are rare and easily overlooked by pathologists, despite their diagnostic significance for Cowden syndrome (PTEN hamartoma tumor syndrome), an inherited multiorgan cancer syndrome. Only 25-35% of patients harbor identifiable PTEN mutations, thus clinical features, like intramucosal lipomas, remain the mainstay of diagnosis. The significance and diagnostic approach to intramucosal lipomas have not been thoroughly addressed in the literature. Intramucosal lipomas are mimicked by pseudolipomatosis coli, an artifactual mucosal gas infiltration from endoscopic insufflation. This differential was investigated by morphology and S-100 immunohistochemistry. Twenty-five colonic intramucosal lipomas were identified from 176 archival gastrointestinal lipomas from 1998 to 2017. Controls included 40 submucosal lipomas and 30 pseudolipomatoses. S-100 immunohistochemistry on all 95 lesions confirmed delicate fat vacuole membranous and nuclear S-100 staining in lipomas absent from pseudolipomatoses. Differentiating morphology between intramucosal lipoma and pseudolipomatosis, respectively, included consistently large, regular fat vacuoles (92% vs 7%), associated spindle cells (80% vs 0%), and mucosal lymphoid aggregate involvement (12% vs 80%). Of the 25 intramucosal lipomas, five patients (20%) had confirmed Cowden syndrome (four with PTEN mutations). In four of these Cowden patients, the intramucosal lipoma was the index diagnostic lesion. Three (12%) intramucosal lipoma patients had additional clinical features associated with Cowden syndrome, but did not meet the diagnostic criteria. Sporadic-type intramucosal lipomas were identified in 17 patients (68%) without evidence of Cowden syndrome, including three with normal PTEN genetic testing. No distinguishing endoscopic or pathologic polyp features were identified between sporadic and syndromic intramucosal lipomas. These data provide evidence that intramucosal lipomas are important harbingers of Cowden syndrome, making up approximately one-third of this series, the largest in the literature. We also show for the first time that two-thirds of intramucosal lipomas are sporadic. Gastrointestinal pathologists, gastroenterologists, and geneticists should increase their awareness of this subtle but diagnosable lesion strongly associated with Cowden syndrome. PMID- 29192651 TI - Myeloid neoplasms with features intermediate between primary myelofibrosis and chronic myelomonocytic leukemia. AB - Monocytosis can develop during disease course in primary myelofibrosis simulating that seen in chronic myelomonocytic leukemia, and should not lead to disease reclassification. In contrast, at presentation, rare cases have clinical, morphologic, and molecular genetic features truly intermediate between primary myelofibrosis and chronic myelomonocytic leukemia. The taxonomy and natural history of these diseases are unclear. We identified cases which either: (1) fulfilled the 2008 World Health Organization criteria for primary myelofibrosis but had absolute monocytosis and, when available, chronic myelomonocytic leukemia related mutations (ASXL1, SRSF2, TET2) or (2) fulfilled criteria of chronic myelomonocytic leukemia but had megakaryocytic proliferation and atypia, marrow fibrosis, and myeloproliferative-type driver mutations (JAK2, MPL, CALR). Patients with established primary myelofibrosis who developed monocytosis and those with chronic myelomonocytic leukemia with marrow fibrosis were excluded. By combining the pathology databases of two large institutions, six eligible cases were identified. Patients were predominantly male and elderly with monocytosis at diagnosis (average 17.5%/2.3 * 103/MUl), organomegaly, primary myelofibrosis-like atypical megakaryocytes admixed with a variable number of chronic myelomonocytic leukemia-like hypolobated forms, variable myelodysplasia, marrow fibrosis and osteosclerosis. All had a normal karyotype and no myelodysplasia-associated cytogenetic abnormalities. Five of the patients in whom a more extensive molecular characterization was performed showed co-mutations involving JAK2 or MPL and ASXL1, SRSF2, TET2, NRAS, and/or KRAS. Disease progression has occurred in all and two have died. Rare patients present with features that overlap between primary myelofibrosis and chronic myelomonocytic leukemia and are thus difficult to classify based on current World Health Organization criteria. Biologically, these cases likely represent primary myelofibrosis with monocytosis, dysplasia, and secondary (non-driver) mutations at presentation. Alternatively, they may represent a true gray zone of neoplasms. Their clinical behavior appears aggressive and innovative therapeutic approaches may be beneficial in this particular subset.

PMID- 29192652 TI - ZC3H7B-BCOR high-grade endometrial stromal sarcomas: a report of 17 cases of a newly defined entity. AB - High-grade endometrial stromal sarcoma likely encompasses underrecognized tumors harboring genetic abnormalities besides YWHAE-NUTM2 fusion. Triggered by three initial endometrial stromal sarcomas with ZC3H7B-BCOR fusion characterized by high-grade morphology and aggressive clinical behavior, we herein investigate the clinicopathologic features of this genetic subset by expanding the analysis to 17 such tumors. All of them occurred in adult women with a median age of 54 (range, 28-71) years. They were predominantly based in the endomyometrium and demonstrated tongue-like and/or pushing myometrial invasion. Most were uniformly cellular and displayed haphazard fascicles of spindle cells with mild to moderate nuclear atypia. Myxoid matrix was seen in 14 of 17 (82%) tumors, and collagen plaques were seen in 8 (47%). The mitotic index was >=10 mitotic figures/10 high power fields (HPFs) in 14 of 17 (82%) tumors with a median of 14.5 mitotic figures/10 HPFs. No foci of conventional or variant low-grade endometrial stromal sarcoma were seen. All tumors expressed CD10 with only limited or absent desmin, SMA and/or h-caldesmon staining. ER and PR expression in >5% of cells was seen in 4 of 12 (33%) tumors. Diffuse cyclin D1 and BCOR immunoreactivity was present in 7 of 8 (88%) and 7 of 14 (50%) tumors, respectively. Fluorescence in situ hybridization or targeted RNA sequencing confirmed ZC3H7B-BCOR fusion in all tumors, including four and two previously diagnosed as myxoid leiomyosarcoma and undifferentiated uterine sarcoma, respectively. Limited clinical data suggest that patients present at higher stage and have worse prognosis compared with published outcomes in low-grade endometrial stromal sarcoma. Tumors with ZC3H7B BCOR fusion constitute a distinct group of endometrial stromal sarcomas with high grade morphology that should be distinguished from other uterine mesenchymal neoplasms that may demonstrate myxoid morphology.

PMID- 29192674 TI - Landscape of the regulatory elements for lysine 2-hydroxyisobutyrylation pathway. AB - Short-chain fatty acids and their corresponding acyl-CoAs sit at the crossroads of metabolic pathways and play important roles in diverse cellular processes. They are also precursors for protein post-translational lysine acylation modifications. A noteworthy example is the newly identified lysine 2 hydroxyisobutyrylation (Khib) that is derived from 2-hydroxyisobutyrate and 2 hydroxyisobutyryl-CoA. Histone Khib has been shown to be associated with active gene expression in spermatogenic cells. However, the key elements that regulate this post-translational lysine acylation pathway remain unknown. This has hindered characterization of the mechanisms by which this modification exerts its biological functions. Here we show that Esa1p in budding yeast and its homologue Tip60 in human could add Khib to substrate proteins both in vitro and in vivo. In addition, we have identified HDAC2 and HDAC3 as the major enzymes to remove Khib. Moreover, we report the first global profiling of Khib proteome in mammalian cells, identifying 6 548 Khib sites on 1 725 substrate proteins. Our study has thus discovered both the "writers" and "erasers" for histone Khib marks, and major Khib protein substrates. These results not only illustrate the landscape of this new lysine acylation pathway, but also open new avenues for studying diverse functions of cellular metabolites associated with this pathway.

PMID- 29192679 TI - Post-LASIK exacerbation of granular corneal dystrophy type 2 in members of a chinese family. AB - PurposeThe post-LASIK exacerbation of corneal dystrophy, otherwise asymptomatic, is almost exclusively associated with the TGFBI gene mutations at codon 124 in exon 4 and codon 555 in exon 12. It is our intention to demonstrate that the pre operative genetic screening for TGFBI mutations should be mandatory for refractive surgery candidates.Patients and MethodsIn this study, we reviewed the proband's post-LASIK slit-lamp and in vivo confocal microscopy images and genetic testing results, and performed genetic testing on eleven additional members of the family to investigate the penetrance of corneal dystrophy in asymptomatic members who carry the mutation.ResultsThe proband demonstrated a post-LASIK exacerbation of Granular Corneal Dystrophy type 2 (GCD2), identified as a TGFBI R124H mutation. Three of the 11 family members tested positive for the same R124H mutation as the proband.ConclusionThe lesson learned from this case is that the genetic screening of TGFBI mutations must be incorporated into the pre-operative screening procedures to prevent exacerbation and recurrence, which eventually could lead to the need for a corneal transplant.

PMID- 29192681 TI - EDTA chelation for symptomatic band keratopathy: results and recurrence. AB - PurposeTo identify causes of symptomatic band keratopathy, and assess the results and long-term recurrence rates following chelation with topical ethylene-diamine tetra-acetic acid (EDTA).Patients and methodsA retrospective review of surgical logbooks identified patients managed by EDTA chelation for symptomatic band keratopathy from 2009 to 2015.ResultsWe identified 108 cases; 89 case notes were available for analysis. Most cases of band keratopathy were idiopathic (36%). The most commonly identified underlying diagnosis was long-term topical glaucoma therapy (27%). Median presenting visual acuity was 6/18 (range 6/6-NPL) with the visual axis affected in 97.8% of cases. Treatment involved corneal epithelium removal, recurrent application of topical EDTA, and subsequent debridement. The mean duration of the operation was 20 min (range 10-45). Mean initial follow-up time was 40 days, and the visual axis was clear in 97.8%. Visual acuity was maintained or improved in 79.8%, with 13.5% improving by two lines or more. The mean length of follow-up was 581 days (median 374, maximum 2438). Twenty-five eyes (28.1%) showed localised recurrence of calcium with a mean time of 546 days (median 374), but only four cases required repeat EDTA chelation. The median time between operations was 430 days. Thirty-two per cent of the recurrence cases were associated with hypotony or chronic presence of silicone oil.ConclusionsChelation of calcium with topical EDTA is a safe and effective treatment for band keratopathy. Visual acuity improves in most eyes and while the rate of recurrence is moderate, the need for retreatment is low (4.5% overall).

AB - PurposeTo evaluate the relationship between central corneal thickness (CCT) and horizontal corneal diameter (HCD) in eyes with uveal coloboma and microcornea.Patients and methodsAll adult patients with uveal coloboma having microcornea in at least one eye and seen between May 2014 and July 2016 at the cataract clinic of our tertiary eye care center were evaluated. The study group comprised 26 colobomatous eyes of 15 patients who had associated microcornea. The control group comprised eyes with uveal coloboma and normal-sized cornea (n=12 eyes of 9 patients). The main outcome measure included the relationship between CCT and HCD in eyes with uveal coloboma and microcornea.ResultsThe mean HCD of the study and control groups was 6.97+/-1.28 and 11.39+/-0.67 mm, respectively. The mean central pachymetry of the study group was 668.4+/-40.2 MUm compared with 555.3+/-41.8 MUm in the control group. In both the groups, CCT was negatively correlated with HCD (R=-0.62 in the study group and R=-0.72 in the control group).ConclusionsUveal colobomatous eyes with microcornea have thicker corneas compared with uveal colobomatous eyes with normal diameter corneas that have normal central corneal thickness. In all the eyes with uveal coloboma, there is a negative correlation between horizontal corneal diameter and central corneal thickness. PMID- 29192684 TI - Early deep anterior lamellar keratoplasty for fungal keratitis poorly responsive to medical treatment. AB - PurposeTo investigate the efficacy of early therapeutic deep anterior lamellar keratoplasty (DALK) in eradicating fungal keratitis that is poorly responsive to medical treatment.Patients and methodsTwenty-three eyes (23 patients) underwent early therapeutic DALK within 15 to 50 days from the onset of symptoms. The adopted eligibility criteria for early DALK included the following: active fungal keratitis affecting the optical zone with ulcer confined in the 6.00 mm central cornea; deeper than 150 MUm but not exceeding 300 MUm; and poorly responsive to medical treatment.ResultsThe big bubble technique was accomplished in 74% (17) of eyes, whereas manual dissection was performed in the remaining 26% (6) of eyes. Histopathological examination did not show any sign of fungal colonization in the peripheral and deep stromal lamellae in any case. All grafts were transparent postoperatively, and no recurrence of infection occurred. Median best spectacle corrected visual acuity significantly improved from 2.0 (1.0 interquartile range) logMAR to 0.1 (0.1 interquartile range) logMAR (P<0.01). The mean follow-up was 32+/-10 months. Neither episode of rejection nor graft failure was noted during the follow-up period.ConclusionEarly DALK could represent a safe therapeutic approach to eradicate fungal keratitis that affects the optical zone and is poorly responsive to medical treatment. PMID- 29192685 TI - The role of keratoprostheses. PMID- 29192686 TI - Evidence summary: the relationship between oral health and dementia. AB - This is the fourth and final paper of a series of reviews undertaken to explore the relationships between oral health and general medical conditions, in order to support teams within Public Health England, health practitioners and policy makers. This review aimed to explore the most contemporary evidence on whether poor oral health and dementia occurs in the same individuals or populations, to outline the nature of the relationship between these two health outcomes and to discuss the implication of any findings for health services and future research. The review was undertaken by a working group comprising consultant clinicians from medicine and dentistry, trainees, public health and academic staff. Whilst other rapid reviews in the current series limited their search to systematic reviews, this review focused on primary research involving cohort and case control studies because of the lack of high level evidence in this new and important field. The results suggest that poor oral hygiene is associated with dementia, and more so amongst people in advanced stages of the disease. Suboptimal oral health (gingivitis, dental caries, tooth loss, edentulousness) appears to be associated with increased risk of developing cognitive impairment and dementia. The findings are discussed in relation to patient care and future research. PMID- 29192687 TI - Projected speciality career choices among undergraduate dental students in Scotland. AB - Background Despite increased numbers of dental specialists, around 90% of dentists in the UK continue to work in general practice. Previous research shows that undergraduate students indicate interest in speciality careers, however few studies have explored which specialties are of interest, when and why. The aim of this study was to explore whether Bachelor of Dental Surgery (BDS) undergraduates attending Glasgow Dental School (GDS) indicate a desire to pursue a speciality career, why, and the extent to which they feel prepared in this regard.Method We conducted an internet-based survey (response rate 81%; n = 331) of all GDS students between October and November 2016.Results One hundred and eighty-six students (56%) had decided to specialise. Seventy-eight percent of these students cited enjoyment of that service, or types of patient seen, as the single most influencing factor on their choice. Oral surgery was the most popular choice where one was indicated (35%), followed by orthodontics (26%). Just 14% of BDS4-5 students felt sufficiently exposed to cases in their chosen speciality. A large majority (88%) said they would like information regarding speciality pathways at BDS3 or before.Conclusions Educators should provide undergraduate students with information about specialties in a structured way, so that they can consider available options. PMID- 29192688 TI - Fluoridation and attention deficit hyperactivity disorder - a critique of Malin and Till (2015). AB - A recent ecological study found a statistically significant association of attention deficit hyperactivity disorder (ADHD) prevalence in youth with exposure to fluoride in fluoridated water. However, it included only household income as a possible covariate. In contrast another study found a significant association of ADHD prevalence with residential altitude. A multiple regression analysis including water fluoridation extent, mean US state elevation and a number of possibly important social factors as covariates showed statistically significant associations of ADHD prevalence in 2011 with altitude and per capita personal income in 2009. There was no statistically significant association of ADHD with the exposure to fluoride when these covariates were included. The ADHD fluoridation study suffers from insufficient consideration of possible risk modifying factors but has been widely cited because its reported findings appear advantageous to political campaigns against community water fluoridation. PMID- 29192689 TI - Using learning outcomes in dental education. AB - Explicitly-stated learning outcomes are an expected, integral part of contemporary under- and postgraduate learning programmes in dentistry. Writing learning outcomes, however, can be challenging and undertaken with a risk of not understanding what is meant by them and what well-constructed outcomes are meant to do. Written badly, learning outcomes will not help capture the goals of educational interventions or, perhaps worse, they end up as nothing more than a complex, frustrating hoop-jumping exercise in both their conception and utilisation. Underlying misconceptions of the purpose of learning outcomes or how to develop them are likely contributors to this situation. We would argue that if one understands the background, construct and intended purpose of learning outcomes we are more likely to write them so that they can actually be applied and therefore used effectively. PMID- 29192690 TI - The relevance of alcohol to dental practice. AB - Alcohol is a very widely used drug which can cause dental disease and influence dental treatment. It is therefore important that dental professionals take an alcohol history from all patients and are aware of how to give alcohol reduction advice. This article discusses the impact of alcohol on oral health, including oral cancer, trauma, halitosis, tooth wear, periodontal disease and caries, with reference to the available literature. It also outlines current alcohol risk level advice and guidance regarding giving alcohol reduction advice in a dental setting. PMID- 29192691 TI - Patient understanding of commonly used oral medicine terminology. AB - Introduction Communication within the doctor-patient relationship is complex due to a variety of reasons; a patient's understanding may not correspond with the clinician's vocabulary, resulting in misunderstanding, anxiety and ill-informed decision making. We investigated the understanding of terminology commonly used in oral and maxillofacial surgery and oral medicine clinics.Methods We investigated patients' understanding using a questionnaire-based study in the out patient setting. Age, gender, first language and highest educational level were recorded. The questionnaire included multiple choice questions regarding patients' understanding of words as well as asking patients to define certain terms. Vocabulary included 'ulcer', 'blister', 'cancer', 'malignant' and 'benign'.Results and conclusions Many patients have difficulty in understanding and explaining commonly used terminology. 'Blister' was the most commonly understood term, while 'benign' and 'lesion' were the least well understood. 'Tumour' was mistakenly thought of as synonymous with 'malignancy' by over a third of patients. Understanding was better among those for whom English was their first language. It is essential that all clinicians modify their language appropriately during consultations in order to deliver information in a comprehensive manner, to educate patients on their condition thus enabling informed decision making by patients. PMID- 29192692 TI - Detecting the earliest radiological signs of bisphosphonate-related osteonecrosis. AB - Introduction Oral bisphosphonates are the most commonly prescribed anti resorptive drugs used in the treatment of osteoporosis, but osteonecrosis of the jaw is a serious complication. The early diagnosis of this destructive side effect is crucial in preventing excessive bone loss, pain and infection.Objective To aid dental practitioners in the early identification of bisphosphonate-related osteonecrosis of the jaw.Method A scoping review was carried out.Data sources We searched MEDLINE via OVID, EMBASE via OVID, Dentistry and Oral Sciences Source (DOSS), Proquest Dissertation and Theses Search, to identify references that described clinical and radiological findings in medication-related osteonecrosis of the jaw (MRONJ).Data selection Nineteen references mentioned the earliest radiological changes in MRONJ with a description of the observations and were included in the analysis.Data synthesis The radiographic signs included osteosclerosis/lysis, widening of the periodontal ligament and thickening of the lamina dura and cortex. To assess the quality of original data on which recommendations had been made, these 19 studies were subjected to a quality appraisal.Conclusion Using bone exposure as a criterion for diagnosis of MRONJ, leads to delayed diagnosis and a poor response to treatment. In those patients at risk of bone exposure with MRONJ, insufficient information is present in the literature to allow the general dental practitioner to reliably identify the radiographic features indicating imminent bone exposure. A well-designed prospective study is needed. PMID- 29192693 TI - Who tells a mother her baby has died? Communication and staff presence during stillbirth delivery and early infant death. AB - OBJECTIVE: Perinatal loss (stillbirth or early infant death) is often a sudden, unexpected event for families. We evaluated who communicates the loss to the parents and who is there for support at the delivery or death. STUDY DESIGN: We conducted a mail survey of 900 bereaved and 500 live-birth mothers to assess emotional, physical and reproductive health outcomes. RESULTS: We had a 44% response rate at 9 months after birth or loss from 377 bereaved mothers and 232 with surviving infants. Bereaved women were less likely to have hospital staff or family members present at delivery. African-American (versus Caucasian) mothers were half as likely to have first heard about their stillbirth from a physician or midwife. CONCLUSION: This is the first large study documenting who communicates perinatal death to families and who is present for support. Hospitals should be aware that many bereaved families may lack support at critical times. PMID- 29192694 TI - Antenatal corticosteroids for the late preterm infant and agnotology. PMID- 29192696 TI - Advances in the synthesis of nitroxide radicals for use in biomolecule spin labelling. AB - EPR spectroscopy is an increasingly useful analytical tool to probe biomolecule structure, dynamic behaviour, and interactions. Nitroxide radicals are the most commonly used radical probe in EPR experiments, and many methods have been developed for their synthesis, as well as incorporation into biomolecules using site-directed spin labelling. In this Tutorial Review, we discuss the most practical methods for the synthesis of nitroxides, focusing on the tunability of their structures, the manipulation of their sidechains into spin labelling handles, and their installation into biomolecules. PMID- 29192697 TI - Mapping piezoelectric response in nanomaterials using a dedicated non-destructive scanning probe technique. AB - There has been tremendous interest in piezoelectricity at the nanoscale, for example in nanowires and nanofibers where piezoelectric properties may be enhanced or controllably tuned, thus necessitating robust characterization techniques of piezoelectric response in nanomaterials. Piezo-response force microscopy (PFM) is a well-established scanning probe technique routinely used to image piezoelectric/ferroelectric domains in thin films, however, its applicability to nanoscale objects is limited due to the requirement for physical contact with an atomic force microscope (AFM) tip that may cause dislocation or damage, particularly to soft materials, during scanning. Here we report a non destructive PFM (ND-PFM) technique wherein the tip is oscillated into "discontinuous" contact during scanning, while applying an AC bias between tip and sample and extracting the piezoelectric response for each contact point by monitoring the resulting localized deformation at the AC frequency. ND-PFM is successfully applied to soft polymeric (poly-l-lactic acid) nanowires, as well as hard ceramic (barium zirconate titanate-barium calcium titanate) nanowires, both previously inaccessible by conventional PFM. Our ND-PFM technique is versatile and compatible with commercial AFMs, and can be used to correlate piezoelectric properties of nanomaterials with their microstructural features thus overcoming key characterisation challenges in the field. PMID- 29192695 TI - Israel transcutaneous bilirubin nomogram predicts significant hyperbilirubinemia. AB - OBJECTIVE: We constructed a transcutaneous bilirubin (TcB) nomogram to represent major sectors of the Israeli population. We studied the risk of hyperbilirubinemia, defined as meeting the requirements for phototherapy, per percentile risk category. STUDY DESIGN: Newborns ?36 weeks gestation were tested daily for TcB, using Drager JM-103 devices, during birth hospitalization. A nomogram was constructed and divided into four risk groups and validated by calculating the need for phototherapy for each group. RESULTS: A total of 3303 measurements were performed on 1059 consecutive newborns including Ashkenazi, Sephardic and mixed Ashkenazi/Sephardic Jews, Arab and Ethiopian Jewish. Phototherapy risk increased progressively and more than 100-fold, from 0/225 in the <40th percentile group through 27/120 (22.5%) for those >95th percentile (relative risk (95% confidence interval) 102 (6 to 1669) for those >95th percentile compared with those <40th percentile). The optimal risk for discriminating the need for phototherapy was >75th percentile (sensitivity 93.33, specificity 59.47). CONCLUSION: The risk of significant hyperbilirubinemia increased progressively with increasing percentile. Newborns >75th percentile groups are at high risk for phototherapy and should be closely monitored. PMID- 29192698 TI - Boron and nitrogen co-doped ordered microporous carbons with high surface areas. AB - Boron and nitrogen co-doped ordered microporous carbons with high surface areas are obtained by using NaY zeolite as a hard template and an ionic liquid, 1-ethyl 3-methylimidazolium tetracyanoborate (EMIT), as a BN source. An acetylene-gas supply during a pyrolysis is effective to avoid the unfavourable reaction of zeolite and EMIT. PMID- 29192699 TI - Design and synthesis of a hybrid framework of indanone and chromane: total synthesis of a homoisoflavanoid, brazilane. AB - A chemical backbone of tetracyclic homoisoflavanoid natural products such as brazilin inspired us to design a new chemical scaffold, 6a,11b-dihydroindeno[2,1 c]chromen-7(6H)-one, which is a hybrid structure of indanone and chromane. Pd catalyzed Suzuki-Miyaura cross-coupling of 4-chloro-2H-chromene-3-carbaldehydes with (hetero)aryl boronic acids was employed as a means to introduce a wide variety of (hetero)aryl groups as the D ring and intramolecular Friedel-Crafts acylation was utilized to construct the C ring of this skeleton. Total synthesis of the natural product, brazilane, was also demonstrated via this new chemical framework. PMID- 29192700 TI - A small molecule for theraNOstic targeting of cancer cells. AB - Thera/NO - a small molecule that is activated by hydrogen peroxide to generate nitric oxide (NO) and a fluorescence signal is reported. Using cancer and primary cells, we show that Thera/NO preferentially releases NO in cancer cells, which can trigger DNA damage and cell death in them. The coupled fluorescence signal facilitated tracking the NO release in living cells without collateral consumption of NO. PMID- 29192702 TI - First-principles study of a MXene terahertz detector. AB - 2D transition metal carbides, nitrides, and carbonitrides called MXenes have attracted increasing attention due to their outstanding properties in many fields. By performing systematic density functional theory calculations, here we show that MXenes can serve as excellent terahertz detecting materials. Giant optical absorption and extinction coefficients are observed in the terahertz range in the most popular MXene, namely, Ti3C2, which is regardless of the stacking degree. Various other optical properties have been investigated as well in the terahertz range for in-depth understanding of its optical response. We find that the thermoelectric figure of merit (ZT) of stacked Ti3C2 flakes is comparable to that of carbon nanotube films. Based on excellent terahertz absorption and decent thermoelectric efficiency in MXenes, we finally suggest the promise of MXenes in terahertz detection applications, which includes terahertz bolometers and photothermoelectric detectors. Possible ZT improvements are discussed in large-scale MXene flake films and/or MXene-polymer composite films.

Application to the total synthesis and absolute configurational assignment of 3alpha,4alpha-epoxy-5beta-pipermethystine. AB - The substrate-controlled asymmetric total synthesis and absolute configurational assignment of biologically active 3alpha,4alpha-epoxy-5beta-pipermethystine, a minor component in the aerial parts of kava, has been achieved by featuring, as a key step, the environmentally friendly and direct synthesis of 2,3-epoxyamides from allyl amines. By using the chiron approach, first a carbohydrate-derived dehydropiperidine was prepared and subjected to a stereoselective tandem C H/C[double bond, length as m-dash]C oxidation reaction. In this attempt, the required alpha,alpha-trans-epoxy-2-piperidone skeleton of the kava metabolite precursor was not achieved, although the tandem oxidation was highly stereoselective. However, starting from non-carbohydrate 3-hydroxy-4,5 dehydropiperidine, and using the same tandem oxidation, the target intermediate was obtained in high yield and complete unprecedented anti-stereoselectivity. Since the proposed mechanistic course of this tandem oxidation implies the transient formation of an alpha,beta-unsaturated amide followed by the subsequent epoxidation reaction, this second approach supports the previously established biotransformation proposal of (-)-pipermethystine to (-)-3alpha,4alpha-epoxy 5beta-pipermethystine. PMID- 29192701 TI - Aptamer-mediated selective delivery of a cytotoxic cationic NHC-Au(i) complex to cancer cells. AB - A novel cationic NHC-Au(i) complex was synthesized and studied for its antitumor activity. For all the cell lines tested, cationic NHC-Au(i) complex 2 shows much higher cytotoxicity than its neutral analogue 1. To achieve selective cancer cell targeting, complex 2 was covalently conjugated to aptamer AS1411, a DNA aptamer with strong binding affinity for nucleolin. The successful conjugation was confirmed by HPLC, gel electrophoresis, fluorescence spectroscopy and UV-Vis absorption. Conjugate AS1411-2 was then examined for its specific targeting and binding ability towards cancer cells over human normal cells using flow cytometry analysis and confocal microscopy. The cytotoxicity of AS1411-2 was then estimated by MTS assay. It was found that AS1411-2 exhibits higher activity than complex 2 towards targeted cells. Importantly, AS1411-2 exhibits much lower cytotoxicity towards healthy normal cell lines. Concurrently, the control groups without the AS1411 aptamer or without the NHC-Au(i) complex do have significant impact on cancer cell viability. PMID- 29192704 TI - Quantitative structure-activity relationships for primary aerobic biodegradation of organic chemicals in pristine surface waters: starting points for predicting biodegradation under acclimatization. AB - Microbial biomass and acclimation can affect the removal of organic chemicals in natural surface waters. In order to account for these effects and develop more robust models for biodegradation, we have compiled and curated removal data for un-acclimated (pristine) surface waters on which we developed quantitative structure-activity relationships (QSARs). Global analysis of the very heterogeneous dataset including neutral, anionic, cationic and zwitterionic chemicals (N = 233) using a random forest algorithm showed that useful predictions were possible (Qext2 = 0.4-0.5) though relatively large standard errors were associated (SDEP ~0.7). Classification of the chemicals based on speciation state and metabolic pathway showed that biodegradation is influenced by the two, and that the dependence of biodegradation on chemical characteristics is non-linear. Class-specific QSAR analysis indicated that shape and charge distribution determine the biodegradation of neutral chemicals (R2 ~ 0.6), e.g. through membrane permeation or binding to P450 enzymes, whereas the average biodegradation of charged chemicals is 1 to 2 orders of magnitude lower, for which degradation depends more directly on cellular uptake (R2 ~ 0.6). Further analysis showed that specific chemical classes such as peptides and organic halogens are relatively less biodegradable in pristine surface waters, resulting in the need for the microbial consortia to acclimate. Additional literature data was used to verify an acclimation model (based on Monod-type kinetics) capable of extrapolating QSAR predictions to acclimating conditions such as in water treatment, downstream lakes and large rivers under MUg L-1 to mg L-1 concentrations. The framework developed, despite being based on multiple assumptions, is promising and needs further validation using experimentation with more standardised and homogenised conditions as well as adequate characterization of the inoculum used.

PMID- 29192706 TI - Estimation of electric field effects on the adsorption of molecular superoxide species on Au based on density functional theory. AB - Superoxide species are key intermediates in the oxygen reduction reactions (ORR) that occur at the cathodes of aprotic metal-air batteries. Herein we report a DFT study of the effects of an externally applied electric field (epsilon) on the stability of various molecular superoxide species, including MO2 (M = Li, Na, K) and O2-, on gold surfaces, which shows that the stability of such species on Au electrodes can be materially affected by the presence of an electric field and solvent molecules, suggesting that such effects should be included in the first principles modeling of cathode reactions in metal-O2 cells. In the epsilon range of +/-0.4 V A-1, the stability of MO2 species is found to vary by up to |0.4| eV on Au(111) and |0.2| eV on Au(211) in vacuo, which is larger than the field effects on the stability of O and OH, key intermediates in the ORR by hydrogen. An aprotic solvent such as dimethyl sulfoxide (DMSO), considered here via the inclusion of explicit DMSO molecules above the Au surfaces, stabilizes all three MO2 species at zero fields and amplifies the field effects on the stability of MO2, on both Au surfaces. The variations in the stability of the molecular MO2 species with epsilon, which have small polarizabilities, are closely approximated by the first-order Stark effect (MU0.epsilon, where MU0 is the static surface dipole moment induced by adsorption at epsilon = 0 V A-1). The superoxide anion (O2-) that has been identified on an under-coordinated Au site has a larger polarizability than the MOx species and a MU0 that is opposite in sign to those of the metal MO2 species, which results in larger errors by the first-order approximation, although its stability varies only moderately under positive electric fields of up to 0.4 V A-1. PMID- 29192707 TI - Polyphenol-enriched berry extracts naturally modulate reactive proteins in model foods. AB - Healthy foods like polyphenol-rich berries and high quality edible proteins are in demand in today's functional food marketplace, but it can be difficult to formulate convenient food products with physiologically-relevant amounts of these ingredients and still maintain product quality. In part, this is because proteins can interact with other food ingredients and precipitate destabilizing events, which can disrupt food structure and diminish shelf life. Proteins in foods can also interact with human receptors to provoke adverse consequences such as allergies. When proteins and polyphenols were pre-aggregated into stable colloidal particles prior to use as ingredients, highly palatable food formulations (with reduced astringency of polyphenols) could be prepared, and the overall structural properties of food formulations were significantly improved. All of the nutritive and phytoactive benefits of the proteins and concentrated polyphenols remained highly bioavailable, but the protein molecules in the particle matrix did not self-aggregate into networks or react with other food ingredients. Both the drainage half-life (a marker of structural stability) and the yield stress (resistance to flow) of model foams made with the protein polyphenol particles were increased in a dose-dependent manner. Of high significance in this complexation process, the reactive allergenic epitopes of certain proteins were effectively blunted by binding with polyphenols, attenuating the allergenicity of the food proteins. Porcine macrophages produced TNF-alpha proinflammatory cytokine when provoked with whey protein, but, this response was blocked completely when the cells were stimulated with particles that complexed whey protein with cinnamon-derived polyphenols. Cytokine and chemokine production characteristic of allergic reactions were blocked by the polyphenols, allowing for the potential creation of hypoallergenic protein-berry polyphenol enriched foods. PMID- 29192708 TI - On the combustion mechanisms of ZrH2 in double-base propellant. AB - Metal hydrides are regarded as a series of promising hydrogen-supplying fuel for solid rocket propellants. Their effects on the energetic and combustion performances of propellants are closely related to their reaction mechanisms. Here we report a first attempt to determine the reaction mechanism of ZrH2, a high-density metal hydride, in the combustion of a double-base propellant to evaluate its potential as a fuel. ZrH2 is determined to possess good resistance to oxidation by nitrocellulose and nitroglycerine. Thus its combustion starts with dehydrogenation to generate H2 and metallic Zr. Subsequently, the newly formed Zr and H2 participate in the combustion and, especially, Zr melts and then combusts on the burning surface which favors the heat feedback to the propellant. This phenomenon is completely different from the combustion behavior of the traditional fuel Al, where the Al particles are ejected off the burning surface of the propellant to get into the luminous flame zone to burn. The findings in this work validate the potential of ZrH2 as a hydrogen-supplying fuel for double base propellants. PMID- 29192709 TI - Conformational disorder and solvation properties of the key-residues of a protein in water-ethanol mixed solutions. AB - A small number of key-residues in a protein sequence play vital roles in the function, stability, and folding of the protein. The nonuniform conformational disorder of a small protein Chymotrypsin Inhibitor 2 (CI2) and its secondary segments has been quantified in the ethanol governed temperature induced unfolding process by estimating its change in configurational entropy in several water-ethanol mixed solutions. Such calculations further assist us in identifying the key-residues, from where the unfolding of the protein was initiated. Our findings match well with the reported experimental results. We then make an attempt to explore the properties of the solvent water and ethanol around the key residues of the protein in its folded and unfolded forms at ambient temperature to identify the individual role of ethanol and water in the protein unfolding. We find that the key-residues of the unfolded protein are in good contact with both water and ethanol as compared to those of the folded protein. In the presence of ethanol, water molecules are noticed to form a rigid structurally bound solvation layer around the key-residues of the protein, irrespective of its conformational state. The restricted translational motion and prominent caging effect of the water and ethanol molecules present around the key-residues of the unfolded protein are a signature of the existence of a rigid mixed water-ethanol layer as compared to that around the folded protein. Furthermore, comparable restricted structural relaxation of the key-residue-water and key-residue-ethanol hydrogen bonds in the unfolded protein as compared to that in the folded one implies that the formation of a strong long-lived hydrogen bonding environment nourishes the unfolding process. We believe that our findings will shed light to several co solvent governed unfolding processes of a protein in general. PMID- 29192710 TI - Dynamical properties of EMIM-SCN confined in a SiO2 matrix by means of 1H NMR relaxometry. AB - 1H nuclear magnetic resonance relaxometry is applied to investigate the translational and rotational dynamics of ionogels composed of an ionic liquid (IL): 1-ethyl-3-methyl-imidazolium-thiocyanate (EMIM-SCN) confined in a nanoporous SiO2 matrix. The relaxation studies were performed in the frequency range of 4 kHz-40 MHz and the temperature range of 223-248 K for different concentrations of the IL; the ratio (no. of moles of IL/no. of moles of SiO2) yields: 1/2, 3/5 and 7/10. A thorough analysis of this large set of experimental data was performed assuming the existence of two fractions of the liquid: a core fraction (near the pore center) and a surface fraction (near the confining walls). It was shown for all concentrations that the confinement does not significantly affect the translational motion near the pore center compared to the dynamics in bulk. The diffusion coefficients in the surface fraction are considerably smaller compared to the core fraction (from one to two orders of magnitude) and the difference becomes larger with increasing temperature. The diffusion coefficients become smaller for higher concentrations - this effect is not large, but visible. Very importantly, it was shown that, despite the interactions with the surface, the diffusion in the surface fraction remains of 3D character. As far as rotational dynamics in the surface fraction is concerned, it slows down compared to the bulk (and the core fraction), but this effect is of the order of factor 2-3. PMID- 29192711 TI - Nitrification in a soil-aquifer treatment system: comparison of potential nitrification and concentration profiles in the vadose zone. AB - The oxidation of ammonium in the vadose zone of soil aquifer systems is discussed and examined by detailed analysis of the depth profiles of dissolved oxygen, nitrate and ammonium concentrations in the vadose zone of a soil-aquifer treatment (SAT) system of a municipal wastewater treatment system of the Tel Aviv metropolitan area. Nitrification kinetics and ammonium adsorption capacity studies show that neither the nitrification rate nor the ammonium adsorption capacity controls the capacity of the Shafdan SAT system for ammonium removal. Evaluation of the ammonium adsorption capacity of the soil reveals that under ideal conditions, a depth of less than 50 cm is sufficient to adsorb all the ammonium supplied in a flooding cycle. In-field studies show that all the ammonium is concentrated within the first 80 cm of the vadose zone. A depth profile of the Potential Nitrification (P.N), a measure of the local amount and activity of nitrifiers, is presented for the first time in the vadose zone of a SAT system showing that there are sufficient nitrifiers to oxidize all the ammonia that is supplied in a flooding cycle within less than 2 h, under optimal microbiological conditions based on the existing nitrifiers and their spatial distribution. The biodegradation rate in the field corresponds to first order ammonium conversion with a kinetic coefficient of 8.0 +/- 0.2 d-1. Accordingly, the average measured rate was 8.6 +/- 5.8 mg NH4+-N per kg per d for in-field tests, which can be compared to the average P.N, with a value of 34.5 +/- 16.8 mg NH4+-N per kg per d. The results suggest that a SAT design, taking into account full ammonium removal capacity, is feasible and can rely on the evaluation of the ammonium adsorption capacity in the SAT soil, the ammonium input and the P.N of the equilibrated target soil under conditions simulating the operation of the infiltrating basins. PMID- 29192712 TI - Effects of the c-Si/a-SiO2 interfacial atomic structure on its band alignment: an ab initio study. AB - The crystalline-Si/amorphous-SiO2 (c-Si/a-SiO2) interface is an important system used in many applications, ranging from transistors to solar cells. The transition region of the c-Si/a-SiO2 interface plays a critical role in determining the band alignment between the two regions. However, the question of how this interface band offset is affected by the transition region thickness and its local atomic arrangement is yet to be fully investigated. Here, by controlling the parameters of the classical Monte Carlo bond switching algorithm, we have generated the atomic structures of the interfaces with various thicknesses, as well as containing Si at different oxidation states. A hybrid functional method, as shown by our calculations to reproduce the GW and experimental results for bulk Si and SiO2, was used to calculate the electronic structure of the heterojunction. This allowed us to study the correlation between the interface band characterization and its atomic structures. We found that although the systems with different thicknesses showed quite different atomic structures near the transition region, the calculated band offset tended to be the same, unaffected by the details of the interfacial structure. Our band offset calculation agrees well with the experimental measurements. This robustness of the interfacial electronic structure to its interfacial atomic details could be another reason for the success of the c-Si/a-SiO2 interface in Si-based electronic applications. Nevertheless, when a reactive force field is used to generate the a-SiO2 and c-Si/a-SiO2 interfaces, the band offset significantly deviates from the experimental values by about 1 eV.

AB - Platinum complexes of the type [Pt(PL)(AL)]2+ where PL is a derivative of 1,10 phenanthroline and AL is cis-1,4-diaminocyclohexane (1,4-dach), have been synthesised and characterised by ultraviolet spectroscopy, elemental microanalysis, nuclear magnetic resonance and X-ray crystallography. The calf thymus DNA binding affinity of these complexes was determined by isothermal titration calorimetry, revealing higher DNA affinity than their 1S,2S diaminocyclohexane analogues. In vitro cytotoxicity was assessed in eleven human cell lines, revealing unexpectedly low activity for the 1,4-dach complexes. PMID- 29192714 TI - 2-(2-Hydroxyphenyl)imidazole-based four-coordinate organoboron compounds with efficient deep blue photoluminescence and electroluminescence. AB - Two new four-coordinate organoboron compounds with 2-(2-hydroxyphenyl)imidazole derivatives as the chelating ligands have been synthesized. They possess high thermal stability and are able to form an amorphous glass state. Crystallographic analyses indicate that the differences in ligand structure cause the change of pipi stacking character. The CH2Cl2 solutions and thin films of these compounds display bright blue emission, and these compounds have appropriate HOMO and LUMO energy levels for carrier injection in OLEDs. By utilizing the good thermal and luminescent properties, as well as the proper frontier orbital energy levels, bright non-doped OLEDs with a simple structure have been realized. Notably, these simple devices show deep blue electroluminescence with the Commission Internationale de l'Eclairage (CIE) coordinate of ca. (0.16, 0.08), which is close to the CIE coordinate of (0.14, 0.08) for standard blue defined by the National Television System Committee. In addition, one of the devices exhibits good performance, showing brightness, current efficiency, power efficiency and external quantum efficiency up to 2692 cd m-2, 2.50 cd A-1, 1.81 lm W-1 and 3.63%, respectively. This study not only provides good deep-blue emitting OLED materials that are rarely achieved by using four-coordinate organoboron compounds, but also allows a deeper understanding of the structure-property relationship of 2-(2-hydroxyphenyl)imidazole-based boron complexes, which benefits the further structural design of this type of material. PMID- 29192715 TI - Tissue or blood: which is more suitable for detection of EGFR mutations in non small cell lung cancer? AB - BACKGROUND: Many studies have evaluated the accuracy of EGFR mutation status in blood against that in tumor tissues as the reference. We conducted this systematic review and meta-analysis to assess whether blood can be used as a substitute for tumor tissue in detecting EGFR mutations. METHODS: Investigations that provided data on EGFR mutation status in blood were searched in the databases of Medline, Embase, Ovid Technologies and Web of Science. The detect efficiency of EGFR mutations in paired blood and tissues was compared using a random-effects model of meta-analysis. Pooled sensitivity and specificity and diagnostic accuracy were calculated by receiver operating characteristic curve. RESULTS: A total of 19 studies with 2,922 individuals were involved in this meta analysis. The pooled results showed the positive detection rate of EGFR mutations in lung cancer tissues was remarkably higher than that of paired blood samples (odds ratio [OR] = 1.47, p<0.001). The pooled sensitivity and specificity of blood were 0.65 and 0.91, respectively, and the area under the receiver operating characteristic curve was 0.89. CONCLUSIONS: Although blood had a better specificity for detecting EGFR mutations, the absence of blood positivity should not necessarily be construed as confirmed negativity. Patients with negative results for blood should decidedly undergo further biopsies to ascertain EGFR mutations. PMID- 29192717 TI - In vitro trials of a wearable artificial kidney (WAK). AB - BACKGROUND: This paper presents results of in vitro trials of a wearable artificial kidney (WAK). MATERIALS AND METHODS: To carry out the trials, a test bench was developed. It consisted of a patient imitator, a tubing set and measuring equipment. RESULTS: Our WAK can eliminate urea, uric acid and creatinine from spent dialysate with mean mass rates of 0.85 +/- 0.1 g/h, 0.10 +/ 0.04 g/h and 0.05 +/- 0.01 g/h, respectively. Concentrations of Na+, Cl- and Ca2+ ions were kept in the 10% range from initial values. We demonstrated that our WAK can operate for 38 hours without having to replace expendable materials. CONCLUSIONS: The WAK that we developed can eliminate metabolites from spent dialysis fluid with mass rates that are sufficient to maintain stable, physiologically normal metabolite concentrations in patients' blood. PMID- 29192716 TI - The cardiotomy reservoir - a preliminary evaluation of a new cell source for cardiovascular tissue engineering. AB - OBJECTIVES: Cell sources for cardiovascular tissue engineering (TE) are scant. However, the need for an ideal TE cardiovascular implant persists. We investigated the cardiotomy reservoir (CR) as a potential cell source that is more accessible and less ethically problematic. METHODS: CR (n = 10) were removed from the bypass system after surgery. Isolation was performed using different isolation methods: blood samples were taken from the cardiopulmonary bypass and centrifuged at low density. The venous filter screen was cut out and placed into petri dishes for cultivation. The spongelike filter was removed, washed and treated in the same way as the blood samples. After cultivation, cell lines of fibroblasts (FB) and endothelial cells (EC) were obtained for analysis. The cells were seeded on polyurethane patches and analyzed via scanning electron microscopy (SEM), Life/Dead assay and immunohistochemistry. RESULTS: No correlation between age, time of surgery and quality of cells was observed. The successful extraction of FB and was proven by positive staining results for TE-7, CD31 and vWF. Cell morphology, cytoskeleton staining and quantification of proliferation using WST-1 assay resembled the cells of the control group in all ways. The topography of a confluent and vital cell layer after cell seeding was displayed by SEM analysis, Life/Dead Assay and immunohistochemistry. The establishment of an extracellular matrix (ECM) was proven by positive staining for collagen IV, laminin, fibronectin and elastin. CONCLUSIONS: Viable FB and EC cell lines were extracted from the CR after surgery. Easy access and high availability make this cell source destined for widespread application in cardiovascular tissue engineering.

However, it can suffer corrosion attacks in some specific aggressive conditions. To further increase its corrosion resistance, it is possible either to modify its surface, tuning either thickness, composition, morphology or structure of the oxide that spontaneously forms on the metal, or to modify its bulk composition. Part 2 of this review is dedicated to the corrosion of titanium and focuses on possible titanium treatments that can increase corrosion resistance. Both surface treatments, such as anodization or thermal or chemical oxidation, and bulk treatments, such as alloying, are considered, highlighting the advantages of each technique.

A review of the mechanisms involved is presented and the role of dialysis access is highlighted. PMID- 29192720 TI - Resolution of reactive angioendotheliomatosis in an arteriovenous fistula with innominate vein angioplasty. AB - INTRODUCTION: Arteriovenous fistulae (AVF)-associated reactive angioendotheliomatosis (RAE) is a very rare entity (three previously reported cases in the literature) that can manifest as extremity wounds. RAE's etiopathology is unknown. CASE DESCRIPTION: We report a case of severe limb threatening upper extremity wound with pathology-proven RAE. This lesion was previously refractory to standard wound care. There was no evidence of limb ischemia or steal syndrome, previously deemed to be the underlying cause of AVF associated RAE in other reports. CONCLUSIONS: Successful endovascular treatment of an ipsilateral innominate vein stenosis led to reduction of venous hypertension, resolution of associated arm edema, and subsequent wound healing. We therefore propose that venous engorgement and hypertension from central venous stenosis is the likely underlying cause for AVF-associated RAE. If this rare entity is encountered in the setting of AVF, there is utility in treating the wound as a sentinel lesion and venography should be conducted to rule out central venous pathology. Vascular intervention complements aggressive local wound management and biopsy is requisite for prompt diagnosis.

AB - INTRODUCTION: Despite the growing number of haemodialysis (HD) patients in India, little is known about vascular access practice. We investigated the use and cost of different vascular accesses by Indian nephrologists. METHODS: An online survey was emailed to 920 Indian nephrologists and 388 (42.1%) responded; 98.5% of whom were responsible for managing dialysis patients, 98% in hospitals. RESULTS: Sixty four percent of patients initiated renal replacement therapy with HD, 7% with peritoneal dialysis, 10% kidney transplantation and 19% conservative care. Forty eight percent of patients were self-paying, 26% had employee reimbursement and 23% had insurance. According to 59% of responders, more than three-quarters of patients started dialysis with uncuffed catheter, less than one-quarter started dialysis with fistula; and very few used grafts or tunnelled catheters. Among prevalent HD patients, over half were dialysing with fistula (79% nephrologists), rather than uncuffed catheters (15% nephrologists) or grafts (<1% nephrologists). Sixteen percent reported at least one catheter-related sepsis in more than half of patients. Placement of uncuffed catheters cost US$160 in 92% facilities, whereas tunnelled catheters cost US$320 in 46% of facilities. An arteriovenous fistula (AVF) could be created for US$160 in 40%, and US$320 in 90% of centres. Thirty-five percent of nephrologists reported that grafts were not placed at their institute and where they were available, the average cost was over US$480. Forty-six percent of nephrologists had access to pre-dialysis clinics, <30% to vascular access programmes, and <17% conducted regular vascular access audits. CONCLUSIONS: The survey provides a snapshot of the current status of vascular access care in HD patients and highlights need for pre-dialysis clinics, vascular access services and registry audits. PMID- 29192722 TI - Cephalic vein transposition is a durable approach to managing cephalic arch stenosis. AB - INTRODUCTION: The proximal cephalic vein that enters the axillary vein (cephalic arch) is a common site of stenosis in patients with upper extremity arteriovenous fistulas for hemodialysis (HD). In this study, we present the outcomes of a series of cephalic vein transposition, to determine its utility in the setting of refractory arch stenosis. METHODS: We conducted a retrospective review of patients undergoing cephalic vein transposition to manage refractory cephalic arch stenosis from January 1, 2008 to August 31, 2015. Demographics, past medical history, access history of the patients as well as procedural details of the surgery to the stenotic segment, patency of the access, and the need for subsequent interventions were recorded. RESULTS: Twenty-three patients underwent a cephalic vein transposition during the study period. The patients undergoing cephalic transposition had their current access for an average of 3.0 +/- 2.6 years and had an average of 2.3 +/- 0.9 interventions on the access prior to the surgery. Complications from the surgery were uncommon (8.7%) and no patient required a temporary tunneled dialysis catheter. The re-intervention rate was 0.2 +/- 0.2 interventions per patient per year. At two years, primary patency was 70.9% and cumulative patency was 94.7% for the patients with cephalic transposition. CONCLUSIONS: Cephalic vein transposition is safe and effective treatment for cephalic arch stenosis without interrupting utilization of the access. The surgical approach to stenosis of the proximal cephalic vein is effective, requires minimal re-interventions, and should be considered for isolated, refractory cephalic arch stenosis in mature arteriovenous fistulas.

PMID- 29192723 TI - Radiation suppresses neointimal hyperplasia through affecting proliferation and apoptosis of vascular smooth muscle cells. AB - PURPOSE: To study the effect of x-ray radiotherapy on vascular smooth muscle cells (VSMCs) and elucidate the mechanisms in preventing neointimal hyperplasia of prosthetic vascular grafts. MATERIALS AND METHODS: In model I, twelve mongrel dogs underwent revascularization with prosthetic grafts and half the dogs underwent irradiation of the grafts at 28 Gy. In model II, human VSMCs (hVSMCs) were maintained and divided into six groups to which external radiation was applied at six different doses: 0 Gy, 2 Gy, 8 Gy, 16 Gy, 24 Gy and 30 Gy. In both models, specimens were harvested and examined by using morphological, immunological, cellular and molecular methods. RESULTS: After irradiation, the neointima thickness was significantly lower in irradiated groups (p<=0.01). The radiotherapy could up-regulate p27kip1, and down-regulate proliferating cell nuclear antigen (PCNA) and S phase kinase associated protein 2 (Skp2). X-ray irradiation inhibits the proliferation of hVSMCs via acting on G1/S phase of cell cycle. The apoptosis of hVSMCs increased significantly with dose and time. The expression of PCNA and Skp2 were decreased after a first increasing trend with dose, but had a significant negative correlation with time. The expression of p27kip1 had a significant positive correlation with dose and time. CONCLUSIONS: Postoperative external fractionated irradiation after prosthetic vessel replacement of the abdominal aorta suppressed the development of hyperplasia in the graft neointima in the short term. There was a prominent time- and dose dependent inhibition of VSMC proliferation by radiation when it was administered.

AB - INTRODUCTION: The study evaluated the Heparin Bioactive Surface (HBS) Viabahn Stent (W.L. Gore & Associates, Flagstaff, Arizona) efficacy in the maintenance or re-establishment of hemodialysis. MATERIALS AND METHODS: Fifty HBS Viabahn stents deployed in 37 consecutive patients with hemodialysis dysfunction from January 2008 to May 2016 were evaluated in a single-institution retrospective review. Outcomes were stent patency intended as primary circuit patency (PP), assisted primary patency (APP), target lesion primary patency (TLPP) and secondary patency (SP). Moreover, the risk factor analysis for hemodialysis dysfunction that required reintervention was performed. A subgroup analysis was conducted to assess patency of Viabahn stent to treat peripheral venous long segment obstruction (LSO). RESULTS: Overall Kaplan-Meyer PPs were 60% at 12 months and 42% at 24 months. Overall TLPP estimated rates were 68% and 49% at 12 and 24 months, respectively. The corresponding SP rates were 85% and 78% at the same period. Estimated PP rates at 12 and 24 months for stent placement after peripheral venous long segment recanalization procedure were 53% and 31%, respectively. Corresponding SP rates were 82% and 68%, respectively. The APP rates were 79% at 12 months and 61% at 24 months. Female sex, access age and thrombosis were associated with reduced primary patency. CONCLUSIONS: Considering the high rates of PP, TLPP, APP and SP, Viabahn stents have been proven effective in maintaining or re-establishing the hemodialysis access. Moreover, stent placement after recanalization of LSO of venous out-flow represented a valid approach to rescue a dysfunctional fistula that would otherwise be abandoned. PMID- 29192726 TI - Outcomes in patients with late sequelae (healed stage) of Legg-Calve-Perthes disease undergoing arthroscopic treatment: retrospective case series. AB - INTRODUCTION: The residual hip deformities after Legg-Calve-Perthes disease (LCPD) cause mechanical symptoms and are associated with a pathomechanical environment that can feature femoroacetabular impingement (FAI). The aim of this study is to evaluate the clinical and radiological outcomes in residual or healed LCPD after arthroscopic treatment. PATIENTS AND METHODS: We retrospectively reviewed patients with LCPD amongst patients with FAI who underwent arthroscopic treatment between January 2009 and June 2013. We determined LCPD through 3 dimensional computed tomographic scans and simple radiography of the hip joint. The clinical outcomes were rated using a visual analogue scale pain score (VAS), the modified Harris Hip Score (mHHS) and hip range of motion (ROM) preoperatively and at the 2-year follow-up. All radiographs were assessed using the Tonnis classification system preoperatively and at the final follow-up of each patient. There were 23 patients (14 men, 9 women) with mean age 26.4 (range, 16-49) years undergoing arthroscopic treatment for FAI symptoms because of residual or healed LCPD. RESULTS: At the 2-year follow-up, the mean VAS had improved significantly from 6.7 to 2.1, the mean mHHS had improved significantly from 62.6 to 87.4, and hip flexion and external rotation had improved significantly from 88.7 degrees to 106.5 degrees and from 20.4 degrees to 33.5 degrees , respectively (all p<0.001). The Tonnis osteoarthritis grade had not changed in any patient at the latest follow-up. CONCLUSIONS: Arthroscopic treatment for sequelae of LCPD relieved symptoms and improved range of motion, making arthroscopic treatment a good option for the sequelae of LCPD. PMID- 29192727 TI - Which is the best bearing surface for primary total hip replacement? A New Zealand Joint Registry study. AB - INTRODUCTION: We have investigated the revision rates of all bearing surface combinations for primary total hip replacement (THR) registered on the New Zealand Joint Registry (NZJR) to determine which coupling has been the most durable and successful over the last 16 years. METHODS: There were 106,139 primary THRs registered, resulting in 4,960 revisions for any cause. We examined all-cause revision rates, reasons for revision and performed survival analyses. RESULTS: Ceramic-on-highly cross-linked polyethylene (CoPx) had the lowest all cause revision rate of 0.54/100-component-years (cys) (95% confidence interval 0.48 to 0.61). This was superior to all other hard-on-soft bearing combinations in unadjusted analysis. Furthermore, the age of patients receiving CoPx was significantly lower than for metal-on-polyethylene (mean 62.9; standard deviation [SD] 10.1 vs. 69.1; SD 9.6; p<0.001). Acetabular loosening was the reason for revision in 14.5% of CoPx, compared to 33% of MoP THRs (p<0.001). Metal-on-metal bearings had the highest revision rate of 1.43/100 cys and were significantly inferior to CoPx (p<0.001). Kaplan-Meier analysis and Cox regression analyses were performed and we adjusted the analyses to control for age, femoral head size, surgical approach and fixation. CONCLUSIONS: CoPx remained the most durable and successful coupling used in primary THR in New Zealand irrespective of age, gender or size of femoral head. PMID- 29192728 TI - Overestimation of the risk of revision with Kaplan-Meier presenting the long-term outcome of total hip replacement in older patients. AB - INTRODUCTION: The purpose of the present study was (i) to review the long-term outcome of cemented Charnley total hip replacements (THRs) performed by 1 surgeon (GH), 20 to 42 years ago, in patients >=60 years, using both the Kaplan-Meier (KM) and the cumulative incidence (CI) methods, and (ii) to compare the estimations of the 2 statistical methods. METHODS: We evaluated the outcome of 306 consecutive primary cemented THRs that were performed in 265 patients. The final clinical, radiographic assessment and satisfaction of living patients were also included. The survivorship was estimated with the use of KM and CI methods and the relative difference between their estimations was calculated. RESULTS: Living patients' final clinical results were significantly improved in comparison with respective preoperative ones, and all the acetabular and 91% of femoral components considered as well fixed. 95% of these patients reported satisfaction. The risk of revision at 25 years, with revision for aseptic loosening for 1 or both components as the endpoint, with 21 hips at risk, assessed with KM analysis was 6.9% and with CI approach was 3.9%. The relative difference between KM and CI estimations was increasing during follow-up, reaching up to 76.8% at 25 years. CONCLUSIONS: We concluded that fixation of implants with cement in older patients had satisfactory long-term results and can serve as a benchmark with which to compare newer fixation methods (hybrid and uncemented) and materials. However, KM method, in studies that include older population with long-term follow-up, may significantly overestimate the risk of revision and clinicians could consider using besides the cumulative incidence of competing risk method. PMID- 29192729 TI - Experience and outcome data of the British non-arthroplasty hip registry. AB - INTRODUCTION: The non-arthroplasty hip registry (NAHR) is a United Kingdom national register that monitors the efficacy of hip preservation surgery. We aim to highlight early experiences of incorporating the NAHR into our practice at a tertiary centre. METHODS: Between December 2013 and February 2015, 381 patients were identified on the NAHR database that had undergone non-arthroplasty hip surgery. Patient-related outcome measures EuroQuol 5D-5L (EQ-5D) and the International Hip Outcome Tool 12 (iHOT-12) were recorded at baseline and 6 months. RESULTS: The 289 arthroscopic surgeries showed a statistical significant difference (p<0.05) in iHOT-12 for both males (45.21-65.07) and females (34.57 to 55.53), and in EQ-5D for both males (0.59-0.75) and females (0.56-0.65). The 92 open procedures showed a statistical significant difference (p<0.05) in both iHOT 12 (31.71-62.42) and EQ-5D (0.54-0.68). CONCLUSIONS: Overall our results from the NAHR indicate hip preservation surgery is effective at relieving pain and improving quality of life in the short term. PMID- 29192730 TI - 3-phase Technicium-99m bone scanning in patients with pain in the hip region after cemented total hip replacement: a multicentre series of 100 cases. AB - INTRODUCTION: The aim of this study was to assess the benefit of a Technetium-99M (HDP) 3-phase bone scan (TPBS) as an additional diagnostic test in the evaluation of pain in the hip region following cemented total hip replacement (THR) surgery. METHODS: A retrospective study over a 24-month period was performed comprising 100 patients investigated with a TPBS. Investigations were summarised and analysed, and were classified as entirely normal, possibly abnormal, and definitely abnormal. RESULTS: 45% (45) of TPBSs were reported as being entirely normal, 50% (50) as possibly abnormal, and 5% (5) as definitely abnormal. During the 24-month study period 230 revision THR procedures were performed at our institution; 10% (24) were investigated with TPBS and 90% (206) were not. 29% (7/24) of patients investigated with a TPBS that subsequently underwent revision THR surgery had an entirely normal preoperative TPBS. 84% (38) with an abnormal TPBS were managed conservatively. A TPBS had a sensitivity of 29% (95% confidence interval (CI), 13%-51%) and a specificity of 50% (95% CI, 38%-62%) in the detection of infection, or loosening with concurrent infection. CONCLUSION: A TPBS should only be considered following clinical evaluation, serological investigation, diagnostic imaging and microbiological analysis of fluid obtained from arthrocentesis by a specialist revision arthroplasty surgeon. A TPBS may be useful in the situation where abnormal serology is present, but where repeated joint aspirations samples are inconclusive. PMID- 29192731 TI - Up to 10-year follow-up of the Symax stem in THA: a Danish single-centre study. AB - INTRODUCTION: The design of the cementless Symax-HA femoral stem is based on geometrical analysis of human femoral anatomy to optimise the fit within the femur. The stem combines an anatomical proximal section enabling a metaphyseal anchorage with a straight distal section. This results in an improved proximal load transfer. We aimed to determine the overall survival of total hip arthroplasty (THA) in patients operated at our institution with the Symax stem. Secondly, we investigated the cause of revision for patients having THA including the Symax stem. METHODS: The study is a registry study with results from a single centre, Vejle Hospital. From the Danish Hip -Arthroplasty Registry, we identified all THAs operated with the Symax stem. The primary outcome was revision. The secondary outcomes were aseptic loosening, periprosthetic fracture, and all other causes for revision. RESULTS: In total, 1,055 THAs were performed in 875 patients. The median 6.5-year survival rate was 97.5% (95% confidence interval [CI]: 96.6%-98.3%). 29 THAs had undergone revision due to the following causes: periprosthetic fracture (n = 11); aseptic loosening of the cup (n = 1); infection (n = 5); dislocation (n = 10); and component failure (n = 2). There was no revision due to aseptic loosening of the stem. CONCLUSIONS: From the Danish Hip Arthroplasty Registry, we identified the overall 6.5-year survival rate to be 95% for cementless THAs. In the present study, the Symax stem has a median 6.5-year survival rate at 97.5% (96.6%-98.3%). No revisions were due to aseptic loosening but the stem had a relative high prevalence of periprosthetic fractures. PMID- 29192732 TI - Leg length discrepancy after total hip arthroplasty: comparison of 3 intraoperative measurement methods. AB - INTRODUCTION: Total hip arthroplasty (THA) is 1 of the most successful and frequent orthopaedic procedures around the world. Leg length discrepancy is reported in 1% to 60% of cases and is 1 of the most frequent causes of patient dissatisfaction and a common reason for litigation. The aim of this study was to compare leg length discrepancies following THA using 3 different intraoperative measuring methods. MATERIAL AND METHODS: We present a prospective cohort study of 454 hips undergoing THA for osteoarthritis between January 2009 and August 2016. We compared postoperative leg length discrepancy using 1 of the following 3 measurement methods: (1A) direct intraoperative comparison of the legs; (1B) measurement with a compass-like device with supra-acetabular fixation, involving length and offset; (1C, D) an intraoperative device that measures the trochanteric/joint ratio. RESULTS: Leg length discrepancy >5 mm was present in 26% of the total study population. Direct intraoperative leg-to-leg assessment resulted in the greatest proportion of leg length discrepancy >5 mm (31%), followed by the compass group (27%) and the least discrepancy was observed in the trochanteric/joint ratio group (15%). The trochanteric/joint ratio assessment method resulted in the greatest reduction in discrepancy when compared to the other methods: discrepancies of 5-10 mm fell by 48% (relative risk [RR] 0.40 CI [confidence interval [CI] 95%, 0.22-0.74), and discrepancies of >=10 mm fell by 59% (RR 0.52; CI 95%, 0.32-0.84). CONCLUSIONS: We conclude that the use of an intraoperative measurement device can reduce the leg length discrepancy, with best results when using the trochanteric/joint ratio device. PMID- 29192733 TI - Systematic review: lack of evidence for the success of revision arthroplasty outcome in younger patients. AB - INTRODUCTION: Total hip arthroplasties (THAs) in younger patients are becoming increasingly popular. However, the outcome of subsequent revisions in younger patients is not well known and, therefore, their success (subsequent revision prosthesis survival) might be overestimated. We investigated available data on the outcome of primary- and subsequent revision THAs performed in the same cohort of patients who underwent primary THA under the age of 50. METHODS: Medline, Embase and the Cochrane Library (CENTRAL) were searched up until April 13, 2016 for studies that reported both the survival of primary and subsequent revisions THA of single cohorts of patients younger than 50. Eligible articles had to include Kaplan Meier analysis or competing risk analysis for survival of the primary THA at a mean follow-up of 10 years, as well as for the subsequent revision THA within the same cohort. RESULTS: We found 4,799 unique records; 43 of which were potentially eligible. Only 1 paper met our inclusion criteria. It reported on the survival of 69 primary prostheses at a mean of more than 10 years follow-up and 13 subsequent revisions. CONCLUSIONS: There is a clear lack of evidence about the outcomes of the revision arthroplasty in younger patients. Only 1 study reported the survival-rate of subsequent revision arthroplasty with the minimum 10-year survival rate of the original THA cohort. In the future, this serious lack of knowledge could result in a large number of patients with no further reconstructive options after failed THA, and a large medical burden for society. PMID- 29192734 TI - Wear rate and medium-term survival of a cemented, moderately cross-linked polyethylene acetabular prosthesis. AB - INTRODUCTION: The moderately cross-linked Depuy Marathon(r) cemented acetabular component was introduced into the UK in 2007. The wear rate for the previously introduced Marathon(r) uncemented acetabular component has been reported to range from 0.06 to 0.01 mm/year. The aim of this study was to present the medium-term results and wear rate of the Marathon(r) cemented prosthesis used in primary total hip arthroplasty. METHODS: 103 Marathon(r) cemented acetabular components were implanted between 2008 and 2009 in primary arthroplasty, who were eligible for this study. All patients received a metal 28-mm head. Mean age was 68 years (range 27-87). Mean clinical follow-up was 55 months (range 50-61). Mean radiological follow-up was 46 months (range 24-57). Wear was calculated on AP radiographs using computer-assisted uni-radiographic technique. RESULTS: The mean wear was 0.37 mm (range 0.0-0.78 mm). The wear rate was calculated as 0.03 mm/year (95% confidence interval 0.02-0.06). Postoperative complications included deep vein thrombosis (2%) and dislocation (0.8%); there were no deep infections. There were no revisions for failure of the Marathon(r) cemented acetabular component. CONCLUSIONS: The Marathon(r) cemented acetabular component demonstrates satisfactory wear rates and survivorship at medium-term follow-up.

PMID- 29192736 TI - Operative findings and complications associated with adjunctive hip arthroscopy in 95 hips undergoing periacetabular osteotomy. AB - PURPOSE: to report our initial experience with adjunctive hip arthroscopy and periacetabular osteotomy (PAO). METHODS: Retrospective review of patients who underwent PAO and ipsilateral hip arthroscopy between 2003 and 2013. Indications for arthroscopy were mechanical symptoms and/or positive magnetic resonance imaging to suggest intra-articular pathology including chondrolabral lesions, ligamentum teres tears and hypertrophy, and synovitis. Preoperative Tonnis arthritis grades, age, sex, operative findings and treatment, complications, and, if available, hip survival were recorded. RESULTS: Of 78 patients (95 hips) included, 64 (82%) were female and 14 (18%) male, average age was 30.6 (14-63) years. Tonnis grades were 0 in 40 hips (42%), 1 in 45 hips (47%), and 2 in 10 hips (11%). No Tonnis 3 hips were included. 84% of hips demonstrated labral pathology. 92% had chondromalacia, which was severe enough in 4 patients to warrant cancellation of PAO; all 4 have subsequently required total hip replacement at short-term follow-up. Labral debridement was performed in 73 hips and refixation in 7. 5 postoperative complications occurred - none major, including 1 fluid extravasation, 1 case of heterotopic ossification, and 3 transient neuropraxias. CONCLUSIONS: Intraarticular pathology is highly prevalent in patients undergoing PAO with mechanical symptoms, and can be safely managed by adjunctive arthroscopy. Complications were minimal in our series and are comparable to reports of PAO without arthroscopy. Arthroscopy can treat pathology that is inaccessible during standalone PAO and permits avoidance of routine arthrotomy, surgical dislocation, rectus release, and futile PAO in cases with severe articular damage. PMID- 29192737 TI - Dreams and Illusions in Adolescents with Terminal Cancer. AB - Being diagnosed with cancer in adolescence generally has important emotional consequences: adolescent cancer patients need to be seen as special cases with particular medical and psychosocial needs. This is especially true when a young patient is faced with a progressive, incurable disease. Herein, we report the story of a 17-year-old girl with a metastatic refractory soft tissue sarcoma who tells her dream to the psychologist of the ward. Telling this narrative is the opportunity to discuss the complex topic of how adolescent cancer patients adapt to the terminal stage of their disease; for example, the patient needs to talk to someone about their fear of dying; the healthcare operators need to be able properly listen and communicate; the patient's trust in the future despite their clinical condition; the necessity to leave space for hope; the useful role of the imagination sphere; the issue of whether and how to tell a person who is terminally ill the truth about their condition. PMID- 29192738 TI - Role of perioperative dynamic sentinel node biopsy for cN0 penile cancer management: experience from an Italian tertiary referral center. AB - PURPOSE: Inguinal lymphadenectomy (iLAD) reduces mortality in patients with cN0 penile cancer but yields high complication rates. Thus, its prophylactic role has been questioned and dynamic sentinel node biopsy (DSNB) was introduced to select men who should undergo the procedure. Our aim was to investigate the accuracy of a contemporary DSNB cohort. METHODS: We performed a retrospective analysis of >=T1 or >=G2 cN0 penile cancer undergoing perioperative DSNB from June 2009 to June 2015 at a tertiary referral center. We excluded men with <18 months follow up or with local recurrence after primary curative treatment. Complications were graded according to the Clavien-Dindo classification. RESULTS: Thirty-five men underwent DSNB; 85.71% had <=T2 penile cancer with <=G2a histology. Per groin detection rate was 80% (scintigraphy being positive bilaterally in 60% and unilaterally in 20.0%). In no cases did DSNB prolong the postoperative course compared to primary surgery. Nine men (n = 15/109 nodes removed) had positive results, 8 of whom underwent iLAD. Among negative DSNB patients, 2 developed nodal penile cancer recurrence; none of them had node biopsy due to inconclusive scintigraphy. At a median follow-up of 42 months (interquartile range 30-78 months), if considering only men with scintigraphy detected inguinal nodes, per patient sensitivity and specificity were 50% and 80% whereas positive predictive value and negative predictive value were 25% and 92.3%, respectively. CONCLUSIONS: Perioperative DSNB is a safe procedure, yielding promising results when performed at a tertiary referral center.

AB - PURPOSE: To investigate disease-free survival (DFS) and prognostic factors following the administration of postoperative (chemo)radiotherapy in patients with early-stage cervical cancers. METHODS: The medical records of 1,069 patients from 10 participating institutions were reviewed. Statistically and clinically established factors were considered as candidates for constructing the prediction model. This model was validated, using bootstrapping to correct for optimistic bias. RESULTS: The 5-year DFS rate was 81.1%, with a median follow-up period of 59.6 months. The statistically significant prognostic factors were as follows: pelvic lymph node metastasis, histologic type, parametrial invasion, lymphovascular space invasion, and tumor size. The nomogram for DFS was constructed, and it demonstrated a good discrimination performance, with an internally validated concordance index of 0.72. CONCLUSIONS: Our predictive model exhibited accurate predictions and may be useful in designing clinical trials to study if further chemotherapy can reduce the recurrence of disease in high-risk patients. PMID- 29192740 TI - Bilateral Parotid Gland Metastases from Gastric Signet-Ring Cell Carcinoma. AB - Introduction Signet-ring cell (SRC) carcinoma is a common subtype of gastric adenocarcinoma associated with poor prognosis. Metastatic involvement of the parotid gland has been reported in gastric cancer patients, but never bilaterally nor in association with the SRC histotype. Here, we report the first case and a brief review of the literature. Case description A 47-year-old woman was referred to our center for a signet-ring gastric carcinoma with synchronous hepatic and peritoneal metastases. After 3 lines of chemotherapy, the patient reported a progressive bilateral enlargement in the periauricolar area. An ultrasound of the salivary glands and a fine needle biopsy were diagnostic for parotid metastases of gastric origin. In the literature, only 3 cases of parotid gland metastases arising from gastric cancer are described - none with a feature of SRC carcinoma. Conclusions To the best of our knowledge, this is the first report of gastric SRC carcinoma with bilateral parotid metastases. This case highlights the importance of considering a parotid enlargement as a possible sign of disease progression in a patient with gastric cancer. Fine-needle biopsy and immunocytochemistry are essential in establishing the origin of the secondary lesion.

AB - PURPOSE:: Two randomized trials in the cytokine era showed that cytoreductive nephrectomy (CN) had a role in metastatic renal cell carcinoma (mRCC), increasing life expectancy. The survival benefit of tyrosine kinase inhibitors (TKIs), including first-line sunitinib and pazopanib, in mRCC has been demonstrated, but the majority of patients enrolled in the pivotal phase III studies had undergone nephrectomy. Therefore it is unknown if similar survival benefit with targeted agents could be achieved without CN. We hypothesize that in these patients CN could increase overall survival (OS) in comparison to targeted therapy without CN. We also will investigate mechanisms of primary and secondary resistance to TKIs in patients with mRCC and identify prognostic or predictive biomarkers. METHODS:: This is a randomized, open-label, controlled, multicenter phase 3 study comparing sunitinib or pazopanib vs CN followed by sunitinib or pazopanib as first-line therapy for patients with mRCC who have not received surgery and prior systemic treatment for metastatic disease. We will identify 270 patients eligible for randomization. The planned treatment duration per patient will be until progressive disease is observed. Secondary endpoints are the evaluation of progression-free survival (PFS) and response rate and the assessment of the safety profile. Exploratory objectives include the evaluation of circulating tumor cells and circulating tumor DNA and correlation with response/resistance to treatment. RESULTS:: The study is enrolling patients. CONCLUSIONS:: The use of CN in addition to targeted therapy in patients with renal cell carcinoma with synchronous metastases could lead to a significant improvement in OS and PFS. PMID- 29192742 TI - Biliary tract rhabdomyosarcoma: a report from the Soft Tissue Sarcoma Committee of the Associazione Italiana Ematologia Oncologia Pediatrica. AB - INTRODUCTION: Rhabdomyosarcoma is a soft tissue malignant musculoskeletal tumor frequent in children. Biliary duct localization is extremely rare, but it is the most common cause of malignant obstructive jaundice in pediatric patients. METHODS: This report describes a series of 10 patients under 18 years of age with biliary tract rhabdomyosarcoma who were enrolled, from 1979 to 2004, in 3 consecutive Italian pediatric cooperative protocols that had been drawn up by the Soft Tissue Sarcoma Committee of the Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP). RESULTS: Considering initial and delayed surgery, tumor resection was achieved in 7 cases, 3 complete with free margins (2 liver transplants) and 4 with microscopic residual disease. Chemotherapy was given to all patients and radiotherapy to 3. At present, 5 patients survive in complete remission 90-200 months after diagnosis while 4 died of disease progression or relapse and 1 of liver transplant-related complications. CONCLUSIONS: Better outcomes in this series were associated with the feasibility of conservative surgery due to the favorable location of the tumor, in particular in the common bile duct. Chemotherapy and radiotherapy might obviate the need for demolitive surgery or liver transplant, which were linked to worse outcomes in our series. PMID- 29192743 TI - Can pancreatic cancer be detected by adrenomedullin in patients with new-onset diabetes? The PaCANOD cohort study protocol. AB - INTRODUCTION: Pancreatic cancer is a leading cause of cancer-related death. Its diagnosis is often delayed and patients are frequently found to have unresectable disease. Patients diagnosed with new-onset diabetes have an 8-fold risk of harboring pancreatic cancer. Adrenomedullin has been claimed to mediate diabetes in pancreatic cancer. New screening tools are needed to develop an early diagnosis protocol. METHODS: Patients aged 45-75 years within 2 years of first fulfilling the ADA criteria for diabetes will be prospectively enrolled in this study. Sepsis, renal failure, microangiopathy, pregnancy, acute heart failure and previous malignancies will be considered as exclusion criteria. RESULTS: 440 patients diagnosed with new-onset diabetes will be enrolled and divided into 2 groups: one with high adrenomedullin levels and one with low adrenomedullin levels. Patients will undergo 3 years' follow-up to detect pancreatic cancer development. CONCLUSIONS: Identifying a marker for pancreatic cancer among high risk patients such as new-onset diabetics might lead to the identification of a subpopulation needing to be screened in order to enable early diagnosis and treatment of a highly lethal tumor. TRIAL REGISTRATION: This trial was registered at ClinicalTrials.gov on May 25, 2015 under registration number NCT02456051. PMID- 29192744 TI - Thirty-day mortality and five-year survival in thoracic surgery: "real-world" assessment of outcomes from a single-institution audit. AB - BACKGROUND: Accurate measurement of outcomes is essential to monitor the effectiveness of public health policies. In Italy, the Ministry of Health has chosen 30-day mortality after major surgical or medical procedures as the main outcome measure, pooling all pulmonary resections for malignancy in a single category. The present audit evaluated all pulmonary resections performed over a 13-year period in a single institution to assess the immediate (30-day mortality) and long-term (5-year survival) outcomes according to type and stage of disease and extent of surgery. METHODS: We analyzed the results of 4,234 first pulmonary resections performed from 2003 to 2015 for lung cancer (2,636), lung metastases (1,080), other primary cancers (259) and benign diseases (259). The median follow up of cancer patients was 4.1 years. RESULTS: Overall 30-day mortality was 1.1%, being 1.2% for lung cancer, 0.3% for lung metastases, 3.5% for pneumonectomies, 1% for lobectomies, and 0.5% for sublobar resections. Among lung cancer patients, 30-day mortality was 0.7% for simple anatomical resections, 2.8% for complex resections, 0.7% for stage I, and 1.6% for higher stages. Overall 5-year survival was 56% for lung cancer, 49% for lung metastases, and 53% for other primary cancers (p = 0.03). According to the surgical procedure for lung cancer, 5-year survival was 60%, 55% and 36% for lobectomies, segmentectomies and pneumonectomies, respectively (p<0.0001). CONCLUSIONS: For better monitoring of thoracic surgery outcomes in a real-world setting, we suggest evaluating lung cancer separately from other thoracic malignancies, and including 5-year survival rates stratified by resection volume and surgical procedure complexity.

PMID- 29192745 TI - Impact of coexistent adenomyosis on outcomes of patients with endometrioid endometrial cancer: a propensity score-matched analysis. AB - PURPOSE: Despite the common occurrence of adenomyosis in endometrial cancer (EC), there is a paucity and conflict in the literature regarding its impact on outcomes of patients. We sought to compare outcomes of patients with endometrioid type EC with or without adenomyosis. METHODS: A total of 314 patients were included in the analysis. Patients were divided into 2 groups according to the presence or absence of adenomyosis. Adenomyosis was identified in 79 patients (25.1%). A propensity score-matched comparison (1:1) was carried out to minimize selection biases. The propensity score was developed through multivariable logistic regression model including age, stage, and tumor grade as covariates. After performing propensity score matching, 70 patients from each group were successfully matched. Primary outcome of the study was disease-free survival (DFS), and the secondary outcomes were overall survival (OS) and disease-specific survival (DSS). RESULTS: Median follow-up time was 61 months for the adenomyosis positive group and 76 months for the adenomyosis negative group. There were no statistically significant differences in 3- and 5-year DFS, OS, and DSS rates between the 2 groups. Five-year DFS was 92% vs 88% (hazard ratio [HR] 1.54 [0.56 4.27]; p = 0.404), 5-year OS was 94% vs 92% (HR 1.60 [0.49-5.26]; p = 0.441), and 5-year DSS was 94% vs 96% (HR 2.51 [0.46-13.71]; p = 0.290) for patients with and without adenomyosis, respectively. CONCLUSIONS: Coexistent adenomyosis in EC is not a prognostic factor and does not impact survival outcomes.

AB - Cancer is a public health problem with an impact on Health Services in Mexico; it is also, one of the leading causes of mortality (mortality rate: 610.6 / 100 000) and is expected to double the total number of new cases by 2035 (GLOBOCAN). The most frequent neoplasms are the malignant tumor of breast, prostate, cervix and uterin, colorectal and pulmonary. The most affected groups are the female, and by age the 65 years and older (INEGI). At the IMSS, the mortality rate for malignant tumors has varied, with a sustained decline since 2010. In the last 15 years there has been a growth of 15% of the Disability Adjusted Life Years; during which the IMSS spent 2% of its current expenditure resources of the Health Insurance and Maternity. The IMSS has a network of medical units capable of attending to the process of prevention, early detection, diagnosis, treatment and rehabilitation of cancer patients. With the commitment of its improvement and to fulfill the National Health Programs, the OncoIMSS Program was created, with a reorganization of the care process with opportunity, quality, optimization of resources, regionalization, strengthening of infrastructure and trained human capital. PMID- 29192748 TI - A middle aged woman with isolated ACTH deficiency associated with transient growth hormone deficiency. AB - Isolated ACTH deficiency (IAD) is a rare entity characterized by secondaryadrenal insufficiency with low levels of serum cortisol, decreasedproduction of ACTH, adequate secretion of other pituitary hormonesand normal pituitary structure on radioimaging. The prevalence ofIAD as a cause of secondary adrenal insufficiency has not been determined.Impairment of growth hormone (GH) secretion has beennoted in 20 to 30% of patients with IAD which is normalized after glucocorticoidreplacement. We report the case of a 50 years-old femalewith symptoms and laboratory results suggestive of adrenal insufficiency.Insulin tolerance test confirmed ACTH and growth hormonedeficiency. The rest of the anterior pituitary hormones were normal. Apituitary MRI was unremarkable. Glucocorticoid replacement therapystarted and eight months afterwards glucagon stimulation test revealedpersistent ACTH deficiency but nor-mal growth hormone secretion. IAD can present with nonspecific symptomsand could be potentially fatal in an acute stressful period. Promptrecognition is essential to decrease morbidity and mortality. PMID- 29192749 TI - Adequate Administration of Perioperative Antibiotics in Orthopedic Patients: Quality Assessment Study. AB - The Centers for Disease Control and Prevention (CDC) estimate thatnearly 500,000 surgical site infections (SSIs) occur annually.[3] SSIs remaina substantial cause of morbidity and mortality among hospitalized patients.For this reason, we developed a quality assessment study with aperioperative antibiotic protocol that included antibiotic type, weight dependentdose, and intraoperative re-dosing regime for the proper administration of prophylaxis antibioticsprior to orthopedic surgery. We restricted our study to knee replacementand hip replacement surgeries. All records from September 2014 to June2015 were taken into consideration (78 cases). Before February 2015(protocol implementation date), only 33% or 13 of 39 cases were correctlydosed. After protocol establishment: 44 % or 17 of 39 cases were correctlydosed. Although our p-value suggests no statistical significance, there wasan increasing trend of adequate antibiotic administration. In conclusion,we need to educate more our nursing staff and implement monthly auditsof our cases to improve our mistakes and ensure that this aspect of practicewill remain in the forefront of perioperative orthopedic surgery care. PMID- 29192750 TI - Association between fine needle aspiration cytologyand final pathology in the diagnosis of thyroid noduleswith surgical indications. AB - Fine needle aspiration of thyroid (FNA) is broadly used as the preferredpreoperatory test to evaluate thyroid nodules. The clinical importance ofthis procedure is primarily related the need to exclude Thyroid Cancer.There are few studies investigating the association between FNA and finalpathology in patients with thyroid nodules with surgical indications.There is no evidence from studies in the southern area of Puerto Rico thatinvestigate this association. This was a randomized cross-sectional study, 82medical records were evaluated. Data were obtained for FNA diagnosis,demographics, body mass index, findings on ultrasound and histopathologyresults. In this study the sensitivity of FNA was 73.53% and specificity of100%. The accuracy of the study was 78%. The study reported a prevalenceof 83% malignant tumors in the final pathology and 61% in the FNA. Thepositive predictive value was 100% and negative 43.75%, suggesting thatFNA is a good diagnostic test to detect thyroid nodules suspicious formalignancy. FNA of 33 patients was reported with undetermined cytopathology.The measure of agreement and correlation coefficient showed amoderate agreement between both studies with a Kappa value of 0.487,suggesting that the test results of FNA and final pathology are associated.Of the indeterminate nodules, final pathology reported 15 benign and 18malignant. This study demonstrated that the FNA is reliable in identifyingthyroid nodules in patients with surgical indications. PMID- 29192751 TI - Anion Exchange Membranes: Enhancement by Addition of Unfunctionalized Triptycene Poly(Ether Sulfone)s. AB - Anion exchange membrane fuel cells are a clean and efficient promising future energy source. However, the development of stable high-performance membranes remains a major challenge. Herein we demonstrate that the addition of unfunctionalized triptycene poly(ether sulfones) into 1-methylimidazolium poly(ether sulfone) enhances membrane's conductivity (up to 0.082 S/cm at 80 degrees C), minimizes dimensional changes over temperatures from 20 to 80 degrees C, and enhances stability with 30% of the initial conductivity maintained after 450 h. These enhancements appear to be the result of nanophase separation and internal free volume. Small angle X-ray scattering and transmission electron microscopy reveal that the internal domain size increases (up to 7.44 nm) with increasing triptycene fraction. PMID- 29192752 TI - Graphene Oxide-Poly(dimethylsiloxane)-Based Lab-on-a-Chip Platform for Heavy Metals Preconcentration and Electrochemical Detection. AB - Herein, we present the application of a novel graphene oxide poly(dimethylsiloxane) (GO-PDMS) composite in reversible adsorption/desorption, including detection of heavy metals. GO-PDMS was fabricated by simple blending of GO with silicon monomer in the presence of tetrahydrofuran, followed by polymerization initiated upon the addition of curing agent. We found GO concentration, curing agent concentration, pH, and contact time among the most important factors affecting the adsorption of Pb(II) used as a model heavy metal. The mechanism of adsorption is based on surface complexation, where oxygen active groups of negative charge can bind with bivalent metal ions Me(II). To demonstrate a practical application of this material, we fabricated microfluidic lab-on-a-chip platform for heavy-metals preconcentration and detection. This device consists of a screen-printed carbon electrode, a PDMS chip, and a GO-PDMS chip. The use of GO-PDMS preconcentration platform significantly improves the sensitivity of electrochemical detection of heavy metals (an increase of current up to 30* was observed), without the need of modifying electrodes or special reagents addition. Therefore, samples being so far below the limit of detection (0.5 ppb) were successfully detected. This approach is compatible also with real samples (seawater) as ionic strength was found as indifferent for the adsorption process. To the best of our knowledge, GO-PDMS was used for the first time in sensing application. Moreover, due to mechanical resistance and outstanding durability, it can be used multiple times unlike other GO-based platforms for heavy-metals adsorption.

AB - We demonstrate that the highly photoredox active metal-organic framework (MOF) MIL-125-NHCyp exhibits crystalline and porosity stability in humid environments for more than 30 days as well as increased hydrophobicity compared to the unfunctionalized framework. This improved stability, in synergy with its high photocatalytic activity, makes this MOF a very promising candidate for large scale applications in CO2 photoreduction. PMID- 29192754 TI - Superior Pseudocapacitive Lithium-Ion Storage in Porous Vanadium Oxides@C Heterostructure Composite. AB - Vanadium oxides are promising anode materials for lithium-ion batteries (LIBs) due to their high capacity, good safety, and low cost. However, their practical application has been deferred by the poor rate capability and cycling stability. In this work, we report the designed synthesis of porous V2O3/VO2@carbon heterostructure electrode for high-performance LIBs. The synergic effects of porous nanostructures, phase hybridization with self-building electric field at heterointerface, and conductive carbon implantation effectively enhance the electronic/ionic conduction and buffer the volume variation in the composite material. Electrochemical tests reveal that the composite electrode exhibits high Li-ion storage capacities of 503 and 453 mAh/g at 100 and 500 mA/g, as well as good cycling stability with a retained capacity of 569 mAh/g over 105 cycles at 100 mA/g. In-depth kinetics analysis discloses that pseudocapacitive Li-ion storage process dominates in the composite electrode, which is probably enabled by efficient coupling of the heterostructure components. The strategy of in situ carbon implantation and phase hybridization presented herein may be extended to other electrode materials for rechargeable batteries with superior electrochemical properties. PMID- 29192755 TI - Tumor-Targeted Accumulation of Ligand-Installed Polymeric Micelles Influenced by Surface PEGylation Crowdedness. AB - With respect to the intriguing biocompatibility and the stealthy functions of poly(ethylene glycol) (PEG), PEGylated nanoparticulates have been intensively engineered for utilities as drug delivery vehicles. To advocate the targeted drug transportation, targeting ligands were strategically installed onto the surface of PEGylated nanoparticulates. The previous in vitro investigations revealed that the ligand-specified cell endocytosis of nanoparticulates was pronounced for the nanoparticulates with adequately high PEG crowdedness. The present study aims to explore insight into the impact of PEGylation degree on in vivo tumor-targeted accumulation activities of cRGD-installed nanoparticulates. The subsequent investigations verified the importance of the PEGylation crowdedness in pursuit of prolonged retention in the blood circulation post intravenous administration. Unprecedentedly, the PEGylation crowdedness was also identified as a crucial important parameter to pursue the tumor-targeted accumulation. A plausible reason is the elevated PEGylation crowdedness eliciting the restricted involvement in nonspecific protein adsorption of nanoparticulates in the biological milieu and consequently pronouncing the ligand-receptor-mediated binding for the nanoparticulates. Noteworthy was the distinctive performance of the class of the proposed systems once utilized for transportation of the mRNA payload to the tumors. The protein expression in the targeted tumors appeared to follow a clear PEGylation crowdedness dependence manner, where merely 2-fold PEGylation crowdedness led to remarkably 10-fold augmentation in protein expression in tumors. Hence, the results provided important information and implications for design of active-targeting PEGylated nanomaterials to fulfill the targeting strategies in systemic applications. PMID- 29192756 TI - Synthesis of Si-Induced MnO/Mn2SiO4@C Cuboids as High-Performance Anodes for Lithium-Ion Batteries. AB - The exploration of anode materials of lithium-ion batteries (LIBs) is still a great challenge because of their low electrical conductivity and poor durability. Transition-metal oxides are proposed as a potential alternative, even though their dimension and structure greatly affect their electrochemical properties. In this study, MnO/Mn2SiO4@C cuboids were prepared via the polymerization-pyrolysis process. Larger MnCO3 precursor particles embedded into a monolithic carbon framework and formed smaller nanoparticles owing to the inducing effect of Si element in phthalocyanino silicon (SiPc), giving MnO/Mn2SiO4@C cuboids. The micron-scaled cuboid composite can lead to higher tap density and greater electrical performance due to lower interparticle resistance. Therefore, the as prepared MnO/Mn2SiO4@C electrode exhibits stable specific capacities of 585.9 and 423.9 mA h g-1 after 1000 discharge/charge cycles at 1 and 2 A g-1, respectively. Meanwhile, an excellent rate capacity of 246.3 mA h g-1 was achieved even at 30 A g-1. Additionally, this facile and economical strategy to improve electrode performance provides a commercially feasible way for the construction of high performance LIBs. PMID- 29192757 TI - Innovations in Undergraduate Chemical Biology Education. AB - Chemical biology derives intellectual vitality from its scientific interface: applying chemical strategies and perspectives to biological questions. There is a growing need for chemical biologists to synergistically integrate their research programs with their educational activities to become holistic teacher-scholars. This review examines how course-based undergraduate research experiences (CUREs) are an innovative method to achieve this integration. Because CUREs are course based, the review first offers strategies for creating a student-centered learning environment, which can improve students' outcomes. Exemplars of CUREs in chemical biology are then presented and organized to illustrate the five defining characteristics of CUREs: significance, scientific practices, discovery, collaboration, and iteration. Finally, strategies to overcome common barriers in CUREs are considered as well as future innovations in chemical biology education. PMID- 29192758 TI - The Thioesterase Domain in Glycopeptide Antibiotic Biosynthesis Is Selective for Cross-Linked Aglycones. AB - The biosynthesis of the glycopeptide antibiotics (GPAs)-which include teicoplanin and vancomycin-is a complex enzymatic process relying on the interplay of nonribosomal peptide synthesis and a cytochrome P450-mediated cyclization cascade. This unique cyclization cascade generates the highly cross-linked state of these nonribosomal peptides, which is crucial for their antimicrobial activity. Given that these essential oxidative transformations occur while the peptide remains bound to the terminal module of the nonribosomal peptide synthetase (NRPS) machinery, it is important to assess the selectivity of the terminal thioesterase (TE) domain and how this domain contributes to the maintenance of an efficient biosynthetic pathway while at the same time ensuring GPA maturation is completed. In this study, we report the in vitro characterization of the thioesterase domain from teicoplanin biosynthesis, the first GPA thioesterase to be characterized. Our results show that the activity of this TE domain relies on the presence of an unusual extended N-terminal linker region that appears to be unique to the NRPS machineries found in GPA biosynthesis. In addition, we show that the activity of this domain against carrier protein bound substrates is dramatically enhanced for mature GPA aglycones as opposed to linear peptides and partially cyclized intermediates. These results demonstrate how the interplay between NRPS and P450s during late stage GPA biosynthesis is not only maintained but also leads to the efficient production of mature GPA aglycones. Thus, GPA TE domains represent another impressive example of the ability of TE domains to act as logic gates during NRPS biosynthesis, ensuring that essential late-stage peptide modifications are completed before catalyzing the release of the mature, bioactive peptide product. PMID- 29192759 TI - Sulfur Nanoparticles with Novel Morphologies Coupled with Brain-Targeting Peptides RVG as a New Type of Inhibitor Against Metal-Induced Abeta Aggregation. AB - Functionalized nanomaterials, which have been applied widely to inhibit amyloid beta protein (Abeta) aggregation, show enormous potential in the field of prevention and treatment of Alzheimer's disease (AD). A significant body of data has demonstrated that the morphology and size of nanomaterials have remarkable effects on their biological behaviors. In this work, we proposed and designed three kinds of brain-targeting sulfur nanoparticles (RVG@Met@SNPs) with novel morphologies (volute-like, tadpole-like, and sphere-like) and investigated the effect of different RVG@Met@SNPs on Abeta-Cu2+ complex aggregation and their corresponding neurotoxicity. Among them, the sphere-like nanoparticles (RVG@Met@SS) exhibited the most effective inhibitory activity, due to their unique mini size effect, and they reduced 61.6% the Abeta-Cu2+ complex aggregation and increased 92.4% SH-SY5Y cell viability in a dose of 10 MUg/mL. In vitro and in vivo, the abilities of different morphologies of RVG@Met@SNPs to cross the blood-brain barrier (BBB) and target brain parenchymal cells were significantly different. Moreover, improvements in learning disability and cognitive loss were shown in the transgenic AD mice model using the Morris water maze test after multiple doses of RVG@Met@SNPs treatment. In general, the purpose of this research is to develop a biological application of sulfur nanoparticles and to provide a novel functionalized nanomaterial to treat AD.

AB - We proposed a simple route for fabrication of the flexible BP nanoflake/carbon nanotube (CNT) composite paper as flexible electrodes in all-solid-state supercapacitors. The highly conductive CNTs not only play a role as active materials but also increase conductivity of the hybrid electrode, enhance electrolyte shuttling and prevent the restacking between BP nanoflakes. The fabricated flexible all-solid-state supercapacitor (ASSP) device at the mass proportion of BP/CNTs 1:4 was found to deliver the highest volumetric capacitance of up to 41.1 F/cm3 at 0.005 V/s, superior to the ASSP based on the bare graphene or BP. The BP/CNTs (1:4) device delivers a rapid charging/discharging up to 500 V/s, which exhibits the characteristic of a high power density of 821.62 W/cm3, while having outstanding mechanical flexibility and high cycling stability over 10 000 cycles (91.5% capacitance retained). Moreover the BP/CNTs (1:4) ASSP device still retains large volumetric capacitance (35.7 F/cm3 at the scan rate of 0.005 V/s) even after 11 months. In addition, the ASSP of BP/CNTs (1:4) exhibits high energy density of 5.71 mWh/cm3 and high power density of 821.62 W/cm3. As indicated in our work, the strategy of assembling stacked-layer composites films will open up novel possibility for realizing BP and CNTs in new-concept thin-film energy storage devices.

AB - A green and scalable route to form a honeycomblike macroporous network by homogeneously weaving V2O5 nanowires and carbon nanotubes (CNTs) was developed. The intertwinement between V2O5 nanowires and CNTs not only integrates nanopores into the macroporous system but also elevates the collection and transfer of charges through the conductive network. The unique combination of V2O5 nanowires and CNTs renders the composite monolith with synergic properties for substantially enhancing electrochemical kinetics of lithiation/delithiation when used as a lithium-ion battery (LIB) cathode. This work presents a useful approach for a large-scale production of cellular monoliths as high-performance LIB cathodes. PMID- 29192763 TI - Assessing Cumulative Effects of Climate Change Manipulations on Phosphorus Limitation in a Californian Grassland. AB - Grasslands throughout the world are responding in diverse ways to changing climate and environmental conditions. In this study we analyze indicators of phosphorus limitation including phosphorus concentrations, phosphorus to nitrogen, and carbon ratios, oxygen isotope ratios of phosphate in vegetation, and phosphatase enzyme activity in soil to shed light on potential effects of climate change on phosphorus availability to grassland vegetation. The study was conducted at the Jasper Ridge Global Change Experiment (JRGCE), California where manipulations mimicking increases in temperature, water, nitrogen and carbon dioxide have been maintained for over 15 years. We compare our results to an earlier study conducted 3 years after the start of the experiment, in order to assess any change in the response of phosphorus over time. Our results suggest that a decade later the measured indicators show similar or only slightly stronger responses. Specifically, addition of nitrogen, the principle parameter controlling biomass growth, increased phosphorus demand but thresholds that suggest P limitation were not reached. A study documenting changes in net primary productivity (NPP) over time at the JRGCE also could not identify a progressive effect of the manipulations on NPP. Combined these results indicate that the vegetation in these grassland systems is not very sensitive to the range of climate parameters tested. PMID- 29192764 TI - Light Control of Protein Solubility Through Isoelectric Point Modulation. AB - We previously described the photoactivated depot or PAD approach that allows for the light control of therapeutic protein release. This approach relies on the ability to use light to change a protein's solubility. Traditionally this was accomplished by linking the protein to an insoluble but injectable polymer via a light cleaved linker. This allows the injected material to remain at the site of injection, until transcutaneous irradiation breaks the link between polymer and protein, permitting the protein to be absorbed. However, there are multiple problems associated with polymer based approaches: The polymer makes up a majority of the material, making it inefficient. In addition, after protein release, the polymer has to be cleared from the body, a significant design challenge. In this work, we create materials that form photoactivated depots of insulin without the need for polymers, by linking photolysis to an isoelectric point shift, which itself is linked to a solubility shift. Specifically, we linked basic groups to insulin via a light cleaved linker. These shift the normal pI of insulin from 5.4 to approximately 7. The result of this incorporation are materials that are completely soluble in mildly acidic solutions but precipitate upon injection into a pH 7 environment, i.e., the skin. We successfully synthesized four such modified insulins, demonstrating that their pI values were shifted in the expected manner. We then analyzed one of them, P2-insulin, in detail, demonstrating that it behaves as designed: It is soluble in a formulation pH of 4, but precipitates at pH 7.2, its approximate pI value. Upon irradiation, the photocleavable link to insulin is broken, and completely native and soluble insulin is released from the depot in a well behaved, first order fashion. These materials are 90% therapeutic, form completely soluble and injectable formulations in mildly acidic conditions, form insoluble depots at neutral pH, efficiently release soluble protein from these depots when irradiated, and leave behind only small easily absorbed molecules after irradiation. As such they approach ideality for photoactivated depot materials.

AB - Polycyclic aromatic hydrocarbons (PAHs) are widely distributed throughout the atmosphere as mixtures attached to ambient particulate matter (PM). PAHs usually elicit similar toxicological pathways but do so with varying levels of efficacy. In this study, we utilized high-throughput screening (HTS) in vitro data of PAHs to predict health risks associated with coarse and fine PM. PM samples with 22 PAH compounds obtained from residential areas close to industrial parks in central Taiwan were analyzed. On the basis of the PM-bound PAH concentrations and their activities reported in HTS assays, we developed a probabilistic model for estimating cumulative exposure of humans to PAHs. Activity-to-exposure ratio (AER) values were calculated to compare relative risks of activating the aryl hydrocarbon receptor (AhR), nuclear factor erythroid 2-related factor 2 (Nrf2), and tumor suppressor gene (p53) when children or adults were exposed to fine or coarse PM in different seasons. On the basis of AER values, the risk of fine PM exposure was relatively higher than the risk of exposure to coarse PM in pathway activation. Children as a susceptible population had a risk of the activating AhR pathway greater than that of adults. Particularly higher risks were observed in winter than in summer. Among three pathways, AhR was the most sensitive one activated by exposure to PAHs. In addition, the activation of the AhR, Nrf2, and p53 pathways was compared by in vitro reporter assays with and without the pre extraction of PAHs from PM. Our proposed novel approach accounts for mixture toxicities in characterizing in vitro pathway-based risks via inhalation exposure to ambient PAHs.

AB - We report here the intrinsic advantages of a special family of porous chalcogenides for CO2 adsorption in terms of high selectivity of CO2/N2, large uptake capacity, and robust structure due to their first-ever unique integration of the chalcogen-soft surface, high porosity, all-inorganic crystalline framework, and the tunable charge-to-volume ratio of exchangeable cations. Although tuning the CO2 adsorption properties via the type of exchangeable cations has been well-studied in oxides and MOFs, little is known about the effects of inorganic exchangeable cations in porous chalcogenides, in part because ion exchange in chalcogenides can be very sluggish and incomplete due to their soft character. We have demonstrated that, through a methodological change to progressively tune the host-guest interactions, both facile and nearly complete ion exchange can be accomplished. Herein, a series of cation-exchanged zeolitic chalcogenides (denoted as M@RWY) were studied for the first time for CO2 adsorption. Samples were prepared through a sequential ion-exchange strategy, and Cs+-, Rb+-, and K+-exchanged samples demonstrated excellent CO2 adsorption performance. Particularly, K@RWY has the superior CO2/N2 selectivity with the N2 adsorption even undetected at either 298 or 273 K. It also has the large uptake of 6.3 mmol/g (141 cm3/g) at 273 K and 1 atm with an isosteric heat of 35-41 kJ mol-1, the best among known porous chalcogenides. Moreover, it permits a facile regeneration and exhibits an excellent recyclability, as shown by the multicycling adsorption experiments. Notably, K@RWY also demonstrates a strong tolerance toward water. PMID- 29192767 TI - Trojan Horse for Light-Triggered Bifurcated Production of Singlet Oxygen and Fenton-Reactive Iron within Cancer Cells. AB - Traditional photodynamic therapy for cancer relies on dye-photosensitized generation of singlet oxygen. However, therapeutically effective singlet oxygen generation requires well-oxygenated tissues, whereas many tumor environments tend to be hypoxic. We describe a platform for targeted enhancement of photodynamic therapy that produces singlet oxygen in oxygenated environments and hydroxyl radical, which is typically regarded as the most toxic reactive oxygen species, in hypoxic environments. The 24-subunit iron storage protein bacterioferritin (Bfr) has the unique property of binding 12 heme groups in its protein shell. We inserted the isostructural photosensitizer, zinc(II) protoporphyrin IX (ZnP), in place of the hemes and extended the surface-exposed N-terminal ends of the Bfr subunits with a peptide targeting a receptor that is hyperexpressed on the cell surface of many tumors and tumor vasculature. We then loaded the inner cavity with ~2500 irons as a ferric oxyhydroxide polymer and finally conjugated 2 kDa polyethylene glycol to the outer surface. We showed that the inserted ZnP photosensitizes generation of both singlet oxygen and the hydroxyl radical, the latter via the reaction of photoreleased ferrous iron with hydrogen peroxide. This targeted iron-loaded ZnP-Bfr construct was endocytosed by C32 melanoma cells and localized to lysosomes. Irradiating the treated cells with light at wavelengths overlapping the ZnP Soret absorption band induced photosensitized intracellular Fe2+ release and substantial lowering of cell viability. This targeted, light-triggered production of intracellular singlet oxygen and Fenton reactive iron could potentially be developed into a phototherapeutic adjunct for many types of cancers.

AB - The magnesium triphenylsilyl complex [(Me3TACD)Mg(SiPh3)] (2) was synthesized from magnesium bis(triphenylsilyl) [Mg(SiPh3)2(THF)2].THF (1; THF = tetrahydrofuran) and the NNNN-type macrocyclic amidotriamine proligand (Me3TACD)H ((Me3TACD)H = Me3[12]aneN4 = 1,4,7-trimethyl-1,4,7,10-tetraazacyclododecane). Treating 2 with AlR3 (R = Me, Et) gave the magnesium triphenylsilyl complexes with "blocked" amido function [(Me3TACD.AlR3)Mg(SiPh3)] (3a: R = Me; 3b: R = Et). Instead of forming a Mg-H bond upon reaction with dihydrogen or hydrosilanes, 2 and 3a,b underwent rapid silyl-silane exchange with hydrosilanes. Treating the ethyl complex [(Me3TACD.AlEt3)MgEt] with H3SiPh gave [(Me3TACD.AlEt3)MgH] (4), albeit not in a reproducible manner. The silyl-hydrosilane exchange allows access to other magnesium silyls of the type [(Me3TACD)Mg(SiR'3)] (5a: SiR'3 = SiH2Ph; 5b: SiR'3 = SiHPh2) and [(Me3TACD.AlR3)Mg(SiR'3)] (6a: SiR'3 = SiH2Ph, R = Me; 6b: SiR'3 = SiH2Ph, R = Et; 7a: SiR'3 = SiHPh2, R = Me; 7b: SiR'3 = SiHPh2, R = Et). The reaction of 2 with H2SiMePh in THF at room temperature resulted in an equilibrium (Keq ~ 1). Protonolysis of 2 with Bronsted acids (HX) 2,5-di-tert butylphenol, phenylacetylene, acetophenone, aniline, and triethylammonium chloride each gave a compound [(Me3TACD)Mg(X)] with the conjugated base coordinated at the magnesium along with HSiPh3. The magnesium silyls 1, 2, and 7b as well as the magnesium hydride 4 contain a distorted square-pyramidal magnesium center according to single-crystal X-ray diffraction. PMID- 29192770 TI - Dioxygen in Polyoxometalate Mediated Reactions. AB - In this review article, we consider the use of molecular oxygen in reactions mediated by polyoxometalates. Polyoxometalates are anionic metal oxide clusters of a variety of structures that are soluble in liquid phases and therefore amenable to homogeneous catalytic transformations. Often, they are active for electron transfer oxidations of a myriad of substrates and upon reduction can be reoxidized by molecular oxygen. For example, the phosphovanadomolybdate, H5PV2Mo10O40, can oxidize Pd(0) thereby enabling aerobic reactions catalyzed by Pd and H5PV2Mo10O40. In a similar vein, polyoxometalates can stabilize metal nanoparticles, leading to additional transformations. Furthermore, electron transfer oxidation of other substrates such as halides and sulfur-containing compounds is possible. More uniquely, H5PV2Mo10O40 and its analogues can mediate electron transfer-oxygen transfer reactions where oxygen atoms are transferred from the polyoxometalate to the substrate. This unique property has enabled correspondingly unique transformations involving carbon-carbon, carbon-hydrogen, and carbon-metal bond activation. The pathway for the reoxidation of vanadomolybdates with O2 appears to be an inner-sphere reaction, but the oxidation of one-electron reduced polyoxotungstates has been shown through intensive research to be an outer-sphere reaction. Beyond electron transfer and electron transfer-oxygen transfer aerobic transformations, there a few examples of apparent dioxygenase activity where both oxygen atoms are donated to a substrate.

AB - Ocimum gratissimum and Ocimum basilicum are plants ethnopharmacologically used to treat diabetes mellitus, a life-threatening disease that affects millions of people worldwide. In order to further understand their antidiabetic potential, which has been previously demonstrated in animal models, we aimed to investigate the acute and chronic effects of major phenolic substances from both plants on insulin secretion and gene expression in pancreatic islets isolated from NMRI mice. Insulin secretion was measured after acute (1 h) and long-term (72 h) incubation of islets with one of four cinnamic acid derivatives (caftaric, caffeic, chicoric, and rosmarinic acids) or a C-glucosylated flavonoid (vicenin 2). All substances acutely enhanced glucose-stimulated insulin secretion (GSIS) from islets at concentrations from 10-10 to 10-6 M. They also increased GSIS after chronic incubation (10-8 M). None of them increased insulin secretion in the presence of low glucose concentration. Furthermore, these substances markedly changed the gene expression profile of key insulin regulatory genes INS1, INS2, PDX1, INSR, IRS1, and proliferative genes as well as glucose transporter 2 (GLUT2), in treated islets. Thus, they may play an important role in diabetes treatment. This is the first report on the insulin-secretory activity of caftaric acid, rosmarinic acid, and vicenin-2. PMID- 29192772 TI - Facile Synthesis of Flowerlike LiFe5O8 Microspheres for Electrochemical Supercapacitors. AB - Facile synthesis of porous and hollow spinel materials is very urgent due to their extensive applications in the field of energy storage. In present work, flowerlike porous LiFe5O8 microspheres etched for 15, 30, and 45 min (named as p LFO-15, p-LFO-30, and p-LFO-45, respectively) are successfully synthesized through a facile chemical etching method based on bulk LiFe5O8 (LFO) particles as precursors, and they are applied as electrode materials for high-performance electrochemical capacitors. In particular, the specific surface area of p-LFO-45 reaches 46.13 m2 g-1, which is 112 times greater than that of the unetched counterpart. Therefore, the p-LFO-45 electrode can achieve a higher capacitance of 278 F g-1 at a scan rate of 5 mV s-1 than the unetched counterpart. Furthermore, the p-LFO-45 electrode presents a good cycling stability with 78.3% of capacitive retention after 2000 cycles, which is much higher than that of the unetched LFO particles (66%). Therefore, the flowerlike porous LFO microspheres are very promising candidate materials for supercapacitor applications. PMID- 29192773 TI - Activity of Tumor Necrosis Factor alpha Is Modulated by Dynamic Conformational Rearrangements. AB - The homotrimeric ligand tumor necrosis factor alpha (TNFalpha) is a key cytokine and immune regulator; however, when deregulated, it leads to several major chronic inflammatory diseases. Perturbation of the protein-protein interface has proven to be an efficient strategy to inactivate TNFalpha, but the atomic resolution mechanism of its inactivation remains poorly understood. Here, we probe the solution structure and dynamics of active and inactive TNFalpha using NMR spectroscopy. The data reveal that TNFalpha undergoes motions on different time scales. Furthermore, by site-directed mutagenesis of residues at the trimerization interface and by targeting the interface with a low molecular weight inhibitor, we show that TNFalpha retains its overall structure and trimeric state. However, upon perturbation, TNFalpha exhibits increased conformational dynamics spanning from the trimerization interface to the regions mediating receptor binding. These findings provide novel insights into the inactivation mechanism of TNFalpha and the basis for strategies to target TNFalpha activity. PMID- 29192774 TI - Nitrogen-Containing Volatiles from Marine Salinispora pacifica and Roseobacter Group Bacteria. AB - Bacteria can produce a wide variety of volatile compounds. Many of these volatiles carry oxygen, while nitrogen-containing volatiles are less frequently observed. We report here on the identification and synthesis of new nitrogen containing volatiles from Salinispora pacifica CNS863 and explore the occurrence in another bacterial lineage, exemplified by Roseobacter-group bacteria. Several compound classes not reported before from bacteria were identified, such as dialkyl ureas and oxalamides. Sulfinamides have not been reported before as natural products. The actinomycete S. pacifica CNS863 produces, for example, sulfinamides N-isobutyl- and N-isopentylmethanesulfinamide (5, 6), urea N,N' diisobutylurea (16), and oxalamide N,N'-diisobutyloxalamide (17). In addition, new imines such as (E)-1-(furan-2-yl)-N-(2-methylbutyl)methanimine (8) and (E)-2 ((isobutylimino)methyl)phenol (13) were identified together with several other imines, acetamides, and formamides. Some of these compounds including the sulfinamides were also released by the Roseobacter-group bacteria Roseovarius pelophilus G5II, Pseudoruegeria sp. SK021, and Phaeobacter gallaeciensis BS107, although generally fewer compounds were detected. These nitrogen-containing volatiles seem to originate from biogenic amines derived from the amino acids valine, leucine, and isoleucine.

AB - The push-pull effect has been widely used to effectively tune pi-electron systems. Herein, we report the synthesis and properties of 1-amino-2 boryldisilene 1 as the first push-pull disilene. Its spectroscopic and structural features show substantial interactions between the Si?Si double bond and the amino and boryl substituents. The pi -> pi* absorption band of 1 is remarkably red-shifted compared to that of the corresponding alkyl-substituted disilene 2. Treatment of 1 with H2 resulted in the cleavage of two molecules of H2 under concomitant formation of the corresponding trihydridodisilane and hydroborane. PMID- 29192776 TI - A Phosphosilicate Compound, NaCa3PSiO8: Structure Solution and Luminescence Properties. AB - NaCa3PSiO8 was synthesized in a microwave-assisted solid-state reaction. The crystal structure of the synthesized compound was solved using a least-squares method, followed by simulated annealing. The compound was crystallized in the orthorhombic space group Pna21, belonging to Laue class mmm. The structure consisted of two layers of cation planes, each of which contained three cation channels. The cation channels in each of the layers ran antiparallel to that of the adjacent layer. All the major cations together constituted four distinct crystallographic sites. The Rietveld refinement of the powder X-ray diffraction data, followed by the maximum-entropy method analysis, confirmed the obtained structure solutions. The electronic band structure of the compound was analyzed through density function theory calculations. Luminescence properties of the compound, upon activating with Eu2+ ions, were analyzed through photoluminescence measurements and decay profile analysis. The compound was found to exhibit green luminescence centered at ~502 nm, with a typical broadband emission due to the transition from the crystal-field split 4f65d to 4f7 levels.

PMID- 29192779 TI - Structure and Bonding in Uranyl(VI) Peroxide and Crown Ether Complexes; Comparison of Quantum Chemical and Experimental Data. AB - The structure, chemical bonding, and thermodynamics of alkali ions in M[12-crown 4]+, M[15-crown-5]+, and M[18-crown-6]+, M[UO2(O2)(OH2)2]+4,5, and M[UO2(O2)(OH)(OH2)]n1-n (n = 4, 5) complexes have been explored by using quantum chemical (QC) calculations at the ab initio level. The chemical bonding has been studied in the gas phase in order to eliminate solvent effects. QTAIM analysis demonstrates features that are very similar in all complexes and typical for electrostatic M-O bonds, but with the M-O bonds in the uranyl peroxide systems about 20 kJ mol-1 stronger than in the corresponding crown ether complexes. The regular decrease in bond strength with increasing M-O bond distance is consistent with predominantly electrostatic contributions. Energy decomposition of the reaction energies in the gas phase and solvent demonstrates that the predominant component of the total attractive (DeltaEelec + DeltaEorb) energy contribution is the electrostatic component. There are no steric constraints for coordination of large cations to small rings, because the M+ ions are located outside the ring plane, [On], formed by the oxygen donors in the ligands; coordination of ions smaller than the ligand cavity results in longer than normal M-O distances or in a change in the number of bonds, both resulting in weaker complexes. The Gibbs energies, enthalpies, and entropies of reaction calculated using the conductor like screening model, COSMO, to account for solvent effects deviate significantly from experimental values in water, while those in acetonitrile are in much better agreement. Factors that might affect the selectivity are discussed, but our conclusion is that present QC methods are not accurate enough to describe the rather small differences in selectivity, which only amount to 5-10 kJ mol-1. We can, however, conclude on the basis of QC and experimental data that M[crown ether]+ complexes in the strongly coordinating water solvent are of outer-sphere type, [M(OH2)n+][crown ether], while those in weakly coordinating acetonitrile are of inner-sphere type, [M-crown ether]+. The observation that the M[UO2(O2)(OH)(OH2)]n1-n complexes are more stable in solution than those of M[crown ether]+ is an effect of the different charges of the rings. PMID- 29192780 TI - Strategy for Modeling the Electrostatic Responses of the Spectroscopic Properties of Proteins. AB - For better understanding and more efficient use of the spectroscopic probes (vibrational and NMR) of the local electrostatic situations inside proteins, appropriate modeling of the properties of those probes is essential. The present study is devoted to examining the strategy for constructing such models. A more well-founded derivation than the ones in previous studies is given in constructing the models. Theoretical analyses are conducted on two representative example cases related to proteins, i.e., the peptide group of the main chains and the CO and NO ligands to the Fe2+ ion of heme, with careful treatment of the behavior of electrons in the electrostatic responses and with verification of consistency with observable quantities. It is shown that, for the stretching frequencies and NMR chemical shifts, it is possible to construct reasonable electrostatic interaction models that encompass the situations of hydration and uniform electric field environment and thus are applicable also to the cases of nonuniform electrostatic situations, which are highly expected for inside of proteins.

AB - We present a route for the functionalization of gold nanoparticles (AuNP) based on phase transfer functionalization in order to optimize the stability and the potential for self-assembly. Depending on the desired size, different ligand exchanges have to be employed: The maximum AuNP size that can be stabilized without concentration loss is 46 nm for polystyrene-based ligands with 5 and 10 kDa. Small particles <12 nm are better stabilized by smaller ligands. We are able to demonstrate that well-ordered close-packed monolayers of 28 nm AuNP covering at least 400 MUm2 are possible with a potential for much larger areas. Such monolayers are of great interest for various fundamental experiments in the context of plasmonics and SERS and for sensor applications.

AB - Electron paramagnetic resonance spectroscopy of the spin probe, TEMPOL, is used to resolve solvent phases that surround the ethanolamine ammonia-lyase (EAL) protein from Salmonella typhimurium at low temperature (T) in frozen, globally polycrystalline aqueous solution and to report on the T dependence of their detectably rigid and fluid states. EAL plays a role in human gut microbiome-based disease conditions, and physicochemical studies provide insight into protein structure and mechanism, toward potential therapeutics. Temperature dependences of the rotational correlation times (tauc; detection range, 10-11 <= tauc <= 10-7 s) and the corresponding weights of TEMPOL tumbling components from 200 to 265 K in the presence of EAL are measured in two frozen systems: (1) water-only and (2) 1% v/v dimethyl sulfoxide (DMSO). In the water-only condition, a protein-vicinal solvent component detectably fluidizes at 230 K and melts the surrounding ice crystalline region with increasing T, creating a bounded, relatively high viscosity aqueous solvent domain, up to 265 K. In the EAL, 1% v/v DMSO condition, two distinct concentric solvent phases are resolved around EAL: protein associated domain (PAD) and mesodomain. The DMSO aqueous mesodomain fluidizes at 200 K, followed by PAD fluidization at 210 K. The interphase dynamical coupling is consistent with the spatial arrangement and significant contact areas of the phases, indicated by the experimentally determined mean volume ratio, V(mesodomain)/V(PAD)/V(protein) = 0.5:0.3:1.0. The results provide a rationale for native chemical reactions of EAL at T < 250 K and an advance toward precise control of solvent dynamics as a tunable parameter for quantifying the coupling between solvent and protein fluctuations and chemical reaction steps in EAL and other enzymes.

PMID- 29192794 TI - Relationship between self-care and comprehensive understanding of heart failure and its signs and symptoms. AB - BACKGROUND: Although incomplete understanding of heart failure and its signs and symptoms appears to be a barrier to successful self-care, there are few studies examining the relationship between self-care and levels of comprehensive understanding of heart failure and its signs and symptoms. AIM: To determine whether incomplete understanding of heart failure and its signs and symptoms is associated with self-care in heart failure patients who were recently discharged from the hospital due to heart failure exacerbation. METHODS: Patients completed the nine-item European Heart Failure Self-care Behavior scale and questionnaire to assess knowledge of heart failure and its signs and symptoms. Three groups were formed by their different levels of understanding of heart failure and its signs and symptoms. Multivariable linear regression was used to determine whether these three levels of understanding groups predicted self-care after controlling for demographic and clinical variables. RESULTS: Of 571 patients 22.1%, 40.1% and 37.8% had poor, moderate, and complete understanding, respectively. Compared with patients in the poor understanding group, patients in complete and moderate understanding groups were more likely to have better adherence to self-care activities (standardized beta = -0.14, 95% confidence interval -3.41, -0.47; standardized beta = -0.19, 95% confidence interval -4.26, -1.23, respectively). CONCLUSIONS: Fewer than half of the patients had a comprehensive understanding of heart failure and its signs and symptoms, which was associated with poor self care. Our study suggests that patient education should include contents to promote comprehensive understanding of heart failure and its symptoms, as well as the importance of self-care behaviors.

AB - We report Developmental Landmark Agnosia (DLA) in a 6-year-old boy (L.G.) who was referred to us for congenital prosopagnosia (see Pizzamiglio et al., 2017 , in which both testing and rehabilitation of Congenital Prosopagnosia are reported). We investigated his performance using a neuropsychological battery and eye movement recordings. The assessment showed the presence of deficits in recognizing familiar places (along with Congenital Prosopagnosia), but not common objects. Eye movement recordings confirmed his problems in recognizing familiar landmarks and misrecognition of unfamiliar places.

AIMS: The aim of this study was to assess the test-retest reliability and responsiveness to change of the symptom-limited bicycle ergometer test, the dynamic unilateral heel-lift test and the unilateral shoulder-flexion test in patients with acute coronary syndrome. METHODS: In a longitudinal study design, a total of 40 patients (mean age 63.8 +/- 9.5 years, five women), with ACS, aged < 75 years, were included at a university hospital in Sweden. The intra-class correlation coefficient (ICC) with a 95% confidence interval, standard error of measurement (SEM) and responsiveness in terms of the minimal detectable change were calculated. RESULTS: Excellent reliability was found, showing ICC values of 0.98 (0.96-0.99), SEM 4.71 for the bicycle ergometer test, ICC 0.87 (0.75-0.93), SEM 4.62 for the shoulder-flexion test and ICC 0.84 (0.71-0.91), SEM 2.24 for the heel-lift test. The minimal detectable change was 13 W, 13 and 6 repetitions for the bicycle ergometer test, shoulder-flexion and heel-lift tests respectively. CONCLUSIONS: The test-retest reliability of clinical tests evaluating physical fitness in patients with acute coronary syndrome included in the SWEDEHEART register was excellent. This makes the future comparison and evaluation of treatment effects in large unselected clinical populations of acute coronary syndrome possible. PMID- 29192796 TI - The effect of weight loss on body composition, serum bone markers, and adipokines in prepubertal obese children after 1-year intervention. AB - : Purpose/Aim: The influence of weight loss on bone turnover and bone quality in childhood remains controversial, but it may implicate interactions between adiposity and bone metabolism. Therefore, we studied the relationships between bone markers and adipokines during weight loss in obese children. MATERIALS AND METHODS: We determined serum leptin, soluble leptin receptor, adiponectin, bone alkaline phosphatase (BALP), C-terminal telopeptide of type I collagen (CTX-I), osteocalcin (OC), carboxylated-OC (Gla-OC), undercarboxylated-OC (Glu-OC), sclerostin, body composition, and bone mineral density (BMD) in 40 obese prepubertal children before and after therapy. The control group, matched for sex and age, consisted of 40 non-obese children. RESULTS: We found that values of the total body less head-bone mineral content (TBLH-BMC) and TBLH-BMD were significantly increased, but TBLH-BMD Z-score was decreased by 25% (p = 0.002) in obese children with weight loss after therapy. We observed increases of CTX-I to OC ratio (p = 0.009), and Gla-OC concentrations (p = 0.049). Changes in TBLH-BMD Z-score in patients were positively correlated with changes in BMI Z-score (p = 0.001), percentage of fat mass (p = 0.004), and BALP activity (p = 0.01). Changes in BALP activity were negatively correlated (p < 0.001) with changes in adiponectin concentrations, while changes in sclerostin levels were positively correlated (p = 0.001) with leptin changes. CONCLUSIONS: We suggest that alterations in adipokines metabolism were associated with a lower rate of bone mineral accrual as a result of decreased bone formation rather than increased bone resorption. The lower rate of bone mass accrual in weight losing children may be an effect of reduced BALP levels related to increase in adiponectin levels. PMID- 29192798 TI - Does Nutrition Education with Fruit and Vegetable Supplementation Increase Fruit and Vegetable Intake and Improve Anthropometrics of Overweight or Obese People of Varying Socioeconomic Status? AB - Fruit and vegetable (F/V) intake is inadequate and obesity is more prevalent among adults of lower socioeconomic status (SES) in the United States. The effect of nutrition education and F/V supplementation on F/V intake and anthropometrics of overweight or obese adults of varying SES was determined. F/V intake was not different between the nutrition education and F/V supplementation groups. Individuals with a graduate degree had significant improvements in fruit intake. Few of the improvements in anthropometrics seen were significant. Future research should focus on specific barriers to F/V intake and include information on total energy intake and expenditure.

AB - According to Article 19 of the Universal Declaration on Human Rights "Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers." The purpose of this paper is to elucidate communication as a human right in the life of a young man called Declan who has Down syndrome. This commentary paper is co-written by Declan, his sister who is a speech-language pathologist (SLP) with an advocacy role, his SLP, and academics. Declan discusses, in his own words, what makes communication hard, what helps communication, his experiences of speech-language pathology, and what he knows about human rights. He also discusses his passion for politics, his right to be an active citizen and participate in the political process. This paper also focuses on the role of speech-language pathology in supporting and partnering with people with communication disabilities to have their voices heard and exercise their human rights. PMID- 29192800 TI - Development of an interprofessional lean facilitator assessment scale. AB - High reliability is important for optimising quality and safety in healthcare organisations. Reliability efforts include interprofessional collaborative practice (IPCP) and Lean quality/process improvement strategies, which require skilful facilitation. Currently, no validated Lean facilitator assessment tool for interprofessional collaboration exists. This article describes the development and pilot evaluation of such a tool; the Interprofessional Lean Facilitator Assessment Scale (ILFAS), which measures both technical and 'soft' skills, which have not been measured in other instruments. The ILFAS was developed using methodologies and principles from Lean/Shingo, IPCP, metacognition research and Bloom's Taxonomy of Learning Domains. A panel of experts confirmed the initial face validity of the instrument. Researchers independently assessed five facilitators, during six Lean sessions. Analysis included quantitative evaluation of rater agreement. Overall inter-rater agreement of the assessment of facilitator performance was high (92%), and discrepancies in the agreement statistics were analysed. Face and content validity were further established, and usability was evaluated, through primary stakeholder post-pilot feedback, uncovering minor concerns, leading to tool revision. The ILFAS appears comprehensive in the assessment of facilitator knowledge, skills, abilities, and may be useful in the discrimination between facilitators of different skill levels. Further study is needed to explore instrument performance and validity. PMID- 29192801 TI - Application of near-infrared spectroscopy to optimize dissolution profiles of tablets according to the granulation mechanism. AB - We developed a method for the optimization of dissolution properties of solid oral dosage forms manufacturing using high shear wet granulation (HSWG) by using near-infrared spectroscopy (NIRS) with chemometrics in small-scale experiments. The changes in rheology and NIR spectra of the granules were monitored to verify the granulation mechanism and determine the suitable water amount for model formulation during the HSWG. Tablets were manufactured by altering the added water amount to investigate the impact of the granulation mechanism on drug product qualities. Model formulation granules were prepared with 10-20% w/w water in a funicular state, corresponding to the plateau region in score plots obtained by principal component analysis (PCA). The dissolution rate of model formulation tablets manufactured with more than 20% w/w of water was significantly delayed while tablets manufactured with 15% w/w water showed 100% dissolution at 15 min. NIRS and PCA are applicable to the optimization of dissolution properties via the process understanding of HSWG at the early formulation development stage and could facilitate drug development. PMID- 29192802 TI - Adhering to the principles of clinical pharmacology - the correct fixed combinations of antihypertensive drugs. AB - INTRODUCTION: Hypertension is one of the primary modifiable risk factor for cardiac and renal diseases with the prevalence around 30-45% of the general population, with a steep increase with ageing. The administration of blood pressure-lowering drugs is to reduce the risk of major clinical cardiovascular outcomes. Hypertension guidelines recommend combination therapy in patients with high cardiovascular risk and with subclinical organ damage as well as when monotherapy fails. Areas covered: As the etiology of essential hypertension is multifactorial, combination therapy using different classes of antihypertensive agents have greater effect than each on its own (synergistic effect), may have better tolerability (two components minimizing each other's side effects) and lead to improved patient compliance. Several studies assess the hypotensive efficacy on drug combination; there are also studies on triple drug combination. Expert commentary: At present, dual and triple combination therapy is available to hypertensive patients with good clinical outcomes, compliance and low profile of side effects. It is critical as patients' adherence to the pharmacological therapy significantly decreases the risk of long-term adverse events including mortality. It appears that combinations not only of hypotensive drugs but also with statins (as well as antidiabetics) will be widely used. PMID- 29192803 TI - Treating hidradenitis suppurativa with photodynamic therapy. AB - Hidradenitis suppurativa is a chronic, recurring, and disabling inflammatory condition of the skin. There is no cure for hidradenitis suppurativa and treatment must be adapted to each individual patient. Several studies have been published since 2004 on the use of photodynamic therapy to treat hidradenitis suppurativa. The use of superficial or interstitial illumination with 5-amino levulinic acid (5-ALA) or methylene blue (MB) have been proposed. Injecting 5-ALA or MB followed by illumination with a fiber optic sensor placed inside the lesion appears to be a better method of treating these thick lesions. PMID- 29192804 TI - Hecogenin exhibits anti-arthritic activity in rats through suppression of pro inflammatory cytokines in Complete Freund's adjuvant-induced arthritis. AB - Hecogenin is a steroidal sapogenin isolated from the leaves of Agave genus species that plays an important role in the treatment of a variety of inflammatory diseases. The aim of the present study was to evaluate the anti arthritic activity of hecogenin in Complete Freund's adjuvant-induced arthritis in rats. The hecogenin (40 ul of 50 ug/kg, orally) and hecogenin + fluticasone (40 ul of 25 ug/kg, each, orally) was tested against Complete Freund's adjuvant induced arthritis in rats by evaluating various parameters such as paw volume, arthritic score, joint diameter, spleen weight, thymus weight, haematological and biochemical parameters and pro-inflammatory cytokines. Histopathological and radiological analyzes of ankle joints were also carried out. Treatment of rats with hecogenin and its combination elicited significant reduction in paw edema, arthritic score and joint diameter. Hecogenin and its combination also inhibited joint destruction in histopathological and radiological analyzes of ankle joint. Hecogenin and its combination significantly increased the levels of red blood cells and hemoglobin but decreased the white blood cell count. The anti-arthritic activity was also confirmed with the change in biochemical parameters and myeloperoxidase assay. In the present investigation, hecogenin and its combination prevent destruction of cartilage and protect synovial membrane with improving health status through haematonic properties and down regulation of various cytokines. Hence, hecogenin may be a potential therapeutic candidate for the treatment of rheumatoid arthritis. PMID- 29192805 TI - Social participation for people with communication disability in coffee shops and restaurants is a human right. AB - Although Article 19 of the Universal Declaration of Human Rights states that "everyone has a right to freedom of opinion and expression", for people with communication disability this may not be a reality. This commentary shares a practical example of how people with communication disabilities together with speech-language pathology (SLP) students, academics and clinical staff co designed and co-implemented a Communication Awareness Training Programme for catering staff to enable communication access in coffee shops and restaurants. This is an example of how SLPs can embrace their social responsibility to break down barriers for people with communication disabilities. This commentary shares the reflections of those involved and how they felt empowered because they had learned new skills and made a difference. This commentary highlights the need for co-design and co-delivery of programs to raise awareness of communication disability among catering staff and how the stories of people with communication disabilities served as a catalyst for change. It also highlights the need to SLPs to move intervention to a social and community space. PMID- 29192806 TI - Impact of Alcohol Tax Increase on Maryland College Students' Alcohol-Related Outcomes. AB - OBJECTIVE: This study A) assessed whether levels of alcohol-related disciplinary actions on college campuses changed among MD college students after the 2011 Maryland (MD) state alcohol tax increase from 6% to 9%, and B) determined which school-level factors impacted the magnitude of changes detected. METHOD: A quasi experimental interrupted time series (ITS) analysis of panel data containing alcohol-related disciplinary actions on 33 MD college campuses in years 2006 2013. Negative binomial regression models were used to examine whether there was a statistically significant difference in counts of alcohol-related disciplinary actions comparing time before and after the tax increase. RESULTS: The ITS anaysis showed an insignificant relationship between alcohol-related disciplinary actions and tax implementation (beta = -.27; p =.257) but indicated that alcohol related disciplinary actions decreased significantly over the time under study (beta = -.05; p =.022). DISCUSSION: Alcohol related disciplinary actions did decrease over time in the years of study, and this relationship was correlated with several school-level characteristics, including school price, school funding type, types of degrees awarded, and specialty. School price may serve as a proxy mediator or confounder of the effect of time on disciplinary actions. PMID- 29192807 TI - Autophagy in advanced low- and high-grade tubular adenocarcinomas of the stomach: An ultrastructural investigation. AB - Autophagy represents a catabolic process in which cellular protein and organelles are engulfed into autophagosomes, digested in lysosomes and reutilized for the cellular metabolism. In neoplastic conditions, autophagy may act either as a tumour suppressor avoiding the accumulation of damaged proteins and organelles or as a mechanism of cell survival promoting the tumour growth. Although enhanced autophagy has been reported in hypoxic areas of solid tumors, there are only few ultrastructural reports concerning the relationships between autophagy and tumor grade. In the present study, we have performed an ultrastructural investigation aimed to document autophagy in a cohort of advanced gastric carcinomas of tubular type, correlating the observed findings with low and high tumor grade. Among 71 surgically resected cases of advanced gastric carcinomas, we have selected twelve low-grade and thirteen high-grade tubular adenocarcinomas. Autophagic vacuoles (AV) were only occasionally found in low-grade tubular carcinomas, while they constituted a frequent finding in high-grade ones (p < 0.01). Moreover, in high grade tubular adenocarcinomas, our data revealed a morphologic association between autophagy and nuclear changes, such as multinucleation, micronucleation and nuclear buds, largely considered as ultrastructural aspects of mitotic instability. However, an increased autophagy was associated with organelle-poor cytoplasm or a senescent phenotype, characterized by lipofuscin granules and cytoplasmic vacuoles. In the light of our observations, it may be suggested that autophagy should be considered a phenomenon mainly related to the cellular differentiation and tumor progression. PMID- 29192808 TI - A splice-site variant in FLVCR1 produces retinitis pigmentosa without posterior column ataxia. AB - FLVCR1 (feline leukemia virus subgroup c receptor 1) is a transmembrane protein involved in the trafficking of intracellular heme. Homozygous variants in FLVCR1 have been described in association with a clinical syndrome of posterior column ataxia with retinitis pigmentosa (PCARP). Here, we describe a patient with non syndromic retinitis pigmentosa homozygous for a splice-site variant in FLVCR1 (c.1092 + 5G>A) without evidence of posterior column ataxia or cerebellar degeneration. We suggest an association between intronic splice-site variants in FLVCR1 and the absence of posterior column degeneration and suggest a hypothesis to explain this observation. Should this association be proven, it would provide valuable prognostic information for patients. Retinal degeneration appears to be the sole clinical manifestation of this FLVCR1 variant; gene therapy approaches using an adeno-associated viral vector with sub-retinal delivery may therefore represent a therapeutic approach to halting retinal degeneration in this patient group. PMID- 29192809 TI - Kidney carcinoid tumor: Histological, immunohistochemical and ultrastructural features. AB - Primary carcinoid tumor of the kidney is uncommon. Only limited morphologic studies have been reported in the literature. In general, renal carcinoid tumor reveals typical morphological features as present in carcinoid tumors in the other organs, i.e. growing as trabeculae intermixed with nests of monotonous cuboidal cells that show "salt and pepper" nuclear appearance. As reported in other organs, different morphological expressions may also present in renal carcinoid tumors, such as papillary, pseudoglandular or solid growth patterns and clear/eosinophilic cytoplasmic changes. These morphological variations may mimic other benign and malignant primary neoplasms in the kidney. Therefore, in some cases, ancillary studies are necessary or even crucial to differentiate carcinoid tumors from other primary renal neoplasms. Herewith, we report two primary renal carcinoid tumors with long follow-up, one showed typical morphological features of carcinoid tumor, and the second one revealed some uncommon histological findings. To differentiate these carcinoid tumors from other primary renal neoplasms and confirm neuroendocrine differentiation, immunohistochemical studies are valuable. In case 2 immunohistochemical stain results were not definitive and electron microscopy was performed confirming the diagnosis of carcinoid tumor. PMID- 29192810 TI - Histological and ultrastructural evaluation of human decellularized matrix as a hernia repair device. AB - Recently, interest has been increasing for human decellularized matrices, due to their ability to reduce numerous side effects related to hernia repair. To date, only animal studies investigated the biological interaction post-implant of human decellularized matrices for soft tissue repair. Therefore, the aim of this study was to evaluate the morphological response one year post implant of human decellularized matrix, through morphological analysis of human biopsies. The histological and ultrastructural results revealed a perfect cellular repopulation and neoangiogenesis, with minimal inflammatory response and a well-organized collagen matrix. The results have indicated that this scaffold can be an effective treatment for hernia. PMID- 29192811 TI - Effects of vitamin D on ovary in DHEA-treated PCOS rat model: A light and electron microscopic study. AB - AIM: The aim of this study was to investigate the effects of vitamin D treatment on ovary in experimentally designed polycystic ovary syndrome of female rats using light and electron microscopic techniques. METHODS: Twenty-four female pre pubertal rats were divided into control, DHEA and DHEA+Vit.D groups. In DHEA group, the PCOS rat model was developed by 6mg/kg/day dehydroepiandrosterone administration as subcutaneously injections. In DHEA+Vit.D group, 6 mg/kg/day DHEA and 120ng/100g/week 1,25(OH)2D3 was performed simultaneously. Controls were injected with vehicle alone. At the end of the 28 days, blood samples were collected and the ovarian tissues were taken for histological examinations. RESULTS: FSH, LH levels, LH/FSH ratio, and testosterone levels showed a significant increase in DHEA group when compared with the control group. Moreover, these measurements were lower in the treatment group than the DHEA group. In DHEA group, increased number of atretic follicles and cystic follicles were seen with light microscopic analysis. Cystic follicles with attenuated granulosa cell layers and thickened theca cell layers and lipid accumulation in interstitial cells were observed by electron microscope. It is observed that atretic and cystic follicles were decreased as a result of vitamin D treatment. CONCLUSION: Our results indicate the curative role of vitamin D treatment on the androgen excess in PCOS rat model which causes abnormalities in ovarian morphology and functions. Vitamin D has positive effects on the hormonal and structural changes observed in PCOS, but it has been concluded that long-term use may be more beneficial.

An Official American Thoracic Society Technical Statement. AB - BACKGROUND: The American Thoracic Society committee on Proficiency Standards for Pulmonary Function Laboratories has recognized the need for a standardized reporting format for pulmonary function tests. Although prior documents have offered guidance on the reporting of test data, there is considerable variability in how these results are presented to end users, leading to potential confusion and miscommunication. METHODS: A project task force, consisting of the committee as a whole, was approved to develop a new Technical Standard on reporting pulmonary function test results. Three working groups addressed the presentation format, the reference data supporting interpretation of results, and a system for grading quality of test efforts. Each group reviewed relevant literature and wrote drafts that were merged into the final document. RESULTS: This document presents a reporting format in test-specific units for spirometry, lung volumes, and diffusing capacity that can be assembled into a report appropriate for a laboratory's practice. Recommended reference sources are updated with data for spirometry and diffusing capacity published since prior documents. A grading system is presented to encourage uniformity in the important function of test quality assessment. CONCLUSIONS: The committee believes that wide adoption of these formats and their underlying principles by equipment manufacturers and pulmonary function laboratories can improve the interpretation, communication, and understanding of test results. PMID- 29192836 TI - Human Information Processing Shapes Language Change. AB - Human languages exhibit both striking diversity and abstract commonalities. Whether these commonalities are shaped by potentially universal principles of human information processing has been of central interest in the language and psychological sciences. Research has identified one such abstract property in the domain of word order: Although sentence word-order preferences vary across languages, the superficially different orders result in short grammatical dependencies between words. Because dependencies are easier to process when they are short rather than long, these findings raise the possibility that languages are shaped by biases of human information processing. In the current study, we directly tested the hypothesized causal link. We found that learners exposed to novel miniature artificial languages that had unnecessarily long dependencies did not follow the surface preference of their native language but rather systematically restructured the input to reduce dependency lengths. These results provide direct evidence for a causal link between processing preferences in individual speakers and patterns in linguistic diversity. PMID- 29192837 TI - Effects of the Nordic Hamstring exercise on sprint capacity in male football players: a randomized controlled trial. AB - : This assessor-blinded, randomized controlled superiority trial investigated the efficacy of the 10-week Nordic Hamstring exercise (NHE) protocol on sprint performance in football players. Thirty-five amateur male players (age: 17-26 years) were randomized to a do-as-usual control group (CG; n = 17) or to 10-weeks of supervised strength training using the NHE in-season (IG; n = 18). A repeated sprint test, consisting of 4 * 6 10 m sprints, with 15 s recovery period between sprints and 180 s between sets, was conducted to evaluate total sprint time as the primary outcome. Secondary outcomes were best 10 m sprint time (10mST) and sprint time during the last sprint (L10mST). Additionally, peak eccentric hamstring strength (ECC-PHS) and eccentric hamstring strength capacity (ECC CAPHS) were measured during the NHE. Ten players were lost to follow-up, thus 25 players were analyzed (CG n = 14; IG n = 11). Between-group differences in mean changes were observed in favor of the IG for sprint performance outcomes; TST ( 0.649 s, p = 0.056, d = 0.38), 10mST (-0.047 s, p = 0.005, d = 0.64) and L10mST ( 0.052 s, p = 0.094, d = 0.59), and for strength outcomes; ECC-PHS (62.3 N, p = 0.006, d = 0.92), and ECC-CAPHS (951 N, p = 0.005, d = 0.95). In conclusion, the NHE showed small-to-medium improvements in sprint performance and large increases in peak eccentric hamstring strength and capacity. TRIAL REGISTRATION NUMBER: NCT02674919. PMID- 29192838 TI - Perceived life stress and anxiety correlate with chronic gastrointestinal symptoms in runners. AB - Numerous causes of exercise-related gastrointestinal (GI) distress exist but scarce research has evaluated potential psychological causes. Runners (74 men, 76 women) prospectively recorded running duration, intensity (Rating of Perceived Exertion [RPE]), and GI symptoms for 30 days. Six GI symptoms were rated on a 0 10 scale. The percentage of runs over 30 days that participants reported at least one upper, lower, or any GI symptom >=3 was calculated. After 30 days, participants completed a questionnaire on GI distress triggers (demographics, anthropometrics, experience, analgesic use, antibiotic use, probiotic consumption, fluid/food intake, stress, anxiety). Stress and anxiety were measured via the Perceived Stress Scale (PSS) and Beck Anxiety Inventory (BAI). The median percentage of runs that participants experienced at least one GI symptom >=3 was 45.6% (interquartile range [IQR], 16.6-67.3%). Age and running experience negatively correlated with GI distress occurrence (rho = -0.17 to 0.34; p < 0.05). Run RPE, probiotic food consumption, PSS scores, and BAI scores positively correlated with GI distress occurrence (rho = 0.18 to 0.36; p < 0.05). Associations between GI distress, stress and anxiety remained significant after adjustment for covariates, except for lower GI symptoms. This study suggests that stress and anxiety contribute to running-related GI distress. PMID- 29192839 TI - Telephone helplines as a source of support for eating disorders: Service user, carer, and health professional perspectives. AB - Access to care for eating disorders can be problematic for numerous reasons including lack of understanding and delays with treatment referrals. Previous research has highlighted the benefits of telephone helplines as an accessible source of support for those who may not wish to access face-to-face support or to fill a gap for those waiting for treatment. This study aimed to gain an insight into the perspectives of those who may use or refer others to a telephone helpline in order to identify the requirements of such a service. Triangulation of service user, carer and health professionals' perspectives resulted in identification of themes relating to the type of support, delivery and practicalities of a helpline. The findings indicated that telephone helplines may offer numerous benefits for individuals with an eating disorder, whether accessed as a first step, alongside treatment or as an extension of this support when in recovery. Additionally helplines may provide an opportunity for carers to access information and discuss their own experiences, while supporting their loved one. Raising awareness of these services is important to encourage those affected by an eating disorder to access and make the most of this type of support. These findings offer an insight into the key requirements for new and existing service development with regard to both the type of support and the method of communication required by individuals with eating disorders. PMID- 29192840 TI - Betulinic acid induces apoptosis and ultrastructural changes in MDA-MB-231 breast cancer cells. AB - The aim of this study is to investigate the effects of betulinic acid (BA) on triple-negative breast cancer MDA-MB-231 cells and observe the ultrastructural changes. The concentration of BA required to induce apoptosis in MDA-MB-231 cells has been previously reported. In this study, a cell counting kit-8 proliferation assay was used to measure cell viability and the apoptosis rate. Western blotting was performed to observe the protein expression levels of Bcl-2. Cell morphology and changes in cell density were observed by microscopy. Electron microscopy revealed pyknotic nuclei as well as vacuoles. Collectively, our results showed the morphological mechanisms by which BA impairs the ultrastructure of MDA-MB-231 cells. PMID- 29192841 TI - A Type 3 Prophage of 'Candidatus Liberibacter asiaticus' Carrying a Restriction Modification System. AB - Prophages, the lysogenic form of bacterial phages, are important genetic entities of 'Candidatus Liberibacter asiaticus' (CLas), a nonculturable alpha proteobacterium associated with citrus Huanglongbing. Two CLas prophages have been described, SC1 (NC_019549.1, Type 1) and SC2 (NC_019550.1, Type 2), which involve the lytic cycle and the lysogenic cycle, respectively. To explore the prophage repertoire, 523 CLas DNA samples extracted from leaf petioles of CLas infected citrus were collected from southern China and surveyed for Type 1 and Type 2 prophages by specific PCR. Eighteen samples were found lacking both prophages. One sample, JXGC, sequenced using Illumina HiSeq, generated >100 million short sequence reads (150 bp per read). Read mapping to known prophage sequences showed a sequence coverage of 46% to SC1 and 50% to SC2. BLAST search using SC1 and SC2 as queries identified three contigs from the JXGC de novo assembly that form a circular P-JXGC-3 (31,449 bp), designated as a new Type 3 prophage. Chromosomal integration of P-JXGC-3 was detected to occur within a helicase gene, resulting in a duplication of this gene. P-JXGC-3 had 36 open reading frames (ORFs), 10 of which were not found in Type 1 or Type 2 prophages, including four genes that encoded a restriction-modification (R-M) system (hsdR, hsdS, hsdM1, and hsdM2). Typed by prophage-specific PCR, the CLas strains in southern China contained all combinations of the three prophage types with the exception of a Type 2-Type 3 combination, suggesting active ongoing prophage phage interactions. Based on gene annotation, P-JXGC-3 is not capable of reproduction via the lytic cycle. The R-M system was speculated to play a role against Type 1 prophage-phage invasion.

Six recreationally active men performed ten repetitions of four activities (walking, jogging, maximal acceleration, and 45o COD) on an indoor court. Activities were repeated twice, in the centre of the court and on the side. Participants wore a receiver tag (Clearsky T6, Catapult Sports) and two reflective markers placed on the tag to allow for comparisons with the criterion system (Vicon). Distance, mean and peak velocity, acceleration, and deceleration were assessed. Validity was assessed via percentage least-square means difference (Clearsky-Vicon) with 90% confidence interval and magnitude-based inference; typical error was expressed as within-subject standard deviation. The mean differences for distance, mean/peak speed, and mean/peak accelerations in the linear drills were in the range of 0.2 12%, with typical errors between 1.2 and 9.3%. Mean and peak deceleration had larger differences and errors between systems. In the COD drill, moderate-to large differences were detected for the activity performed in the centre of the court, increasing to large/very large on the side. When filtered and smoothed following a similar process, the UWB-based positioning system had acceptable validity, compared to Vicon, to assess movements representative of indoor sports.

AB - INTRODUCTION: Hepatotoxicity is a major complication of acetaminophen (APAP), a widely used analgesic and antipyretic drug. Resveratrol (RSV) is a naturally occurring diphenol and it has anticancer, antioxidant, and anti-inflammatory properties. OBJECTIVES: In this study, the beneficial effects of RSV on APAP induced hepatotoxicity was investigated in rats. MATERIALS AND METHODS: Group 1: Ethanol, Group 2: Saline, Group 3: RSV (10 mg/kg/ip), Group 4: APAP (1000 mg/kg/ip/single dose), Group 5: APAP+RSV (20 min after administration of APAP). The rats were sacrificed 24 h after administration of APAP. Light and electron microscopic changes were evaluated. Levels of malondialdehyde (MDA) and glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD) activities were determined in liver tissue. RESULTS: Rats of the ethanol, saline, and RSV groups did not present any histopathological alterations. In the APAP group, we observed vascular congestion, necrosis, inflammation, sinusoidal dilatation, and loss of glycogen content. In the APAP+RSV group, these changes were markedly reduced. iNOS immunostaining showed very weak positive stained hepatocytes the sections of control, saline, and RSV groups. However, in the APAP group, iNOS immunostaining was most evident in pericentral hepatocytes. In the same areas in APAP+RSV group, intensity of iNOS immunostaining decreased. A significant increase in MDA and decreases in GSH level, CAT, and SOD activity indicated that APAP-induced hepatotoxicity was mediated through oxidative stress. Significant beneficial changes were noted in tissue oxidative stress indicators in rats treated with RSV. CONCLUSION: These biochemical, histopathological, and ultrastructural findings revealed that RSV reduced the severity of APAP-induced alterations in liver. PMID- 29192843 TI - Somatostatin in Alzheimer's disease: A new Role for an Old Player. AB - The amyloid beta (Abeta) peptide is central to the pathogenesis of Alzheimer's disease (AD). Insights into Abeta-interacting proteins are critical for understanding the molecular mechanisms underlying Abeta-mediated toxicity. We recently undertook an in-depth in vitro interrogation of the Abeta1-42 interactome using human frontal lobes as the biological source material and taking advantage of advances in mass spectrometry performance characteristics. These analyses uncovered the small cyclic neuropeptide somatostatin (SST) to be the most selectively enriched binder to oligomeric Abeta1-42. Subsequent validation experiments revealed that SST interferes with Abeta fibrillization and promotes the formation of Abeta assemblies characterized by a 50-60 kDa SDS resistant core. The distributions of SST and Abeta overlap in the brain and SST has been linked to AD by several additional observations. This perspective summarizes this body of literature and draws attention to the fact that SST is one of several neuropeptide hormones that acquire amyloid properties before their synaptic release. The latter places the interaction between SST and Abeta among an increasing number of observations that attest to the ability of amyloidogenic proteins to influence each other. A model is presented which attempts to reconcile existing data on the involvement of SST in the AD etiology. PMID- 29192845 TI - Systematic alteration of apoptosis: a review with ultrastructural observations on leukemia cells in vivo. AB - The ultrastructural characteristics of apoptosis have been described microscopically for four decades. Alterations of nuclei, apoptotic bodies, cytoplasm, and some organelles have been illustrated and investigated during apoptosis. The successive changes of cellular components corresponding with differentiation of apoptotic cells are illustrated in the present review, based on ultrastructural observation of leukemia cells of patients in our routine clinic work by transmission electron microscopy. Most electron micrographs demonstrated that membranous components of nuclear envelop, rough endoplasmic reticulum and Golgi apparatus, and mitochondria were degenerated step by step during apoptosis. The successive images suggested that the endoplasmic reticulum and Golgi apparatus were transferred to cell surface from cytoplasm and participated in formation of apoptotic bodies in apoptosis, although relevant clinical data and more experimental evidence were needed for restraining of leukemia cases from diagnostic work randomly in recent decades. PMID- 29192846 TI - A cross-sectional and prospective analyse of reallocating sedentary time to physical activity on children's cardiorespiratory fitness. AB - Cardiorespiratory fitness (CRF) is associated with health benefits in children, improving cardiac morphology, cardiovascular disease risk factors, and biological outcomes. This study aimed to examine the substitution effects of displaying a fixed duration of sedentary time with a fixed duration of physical activity (PA) at different intensities on children's CRF. A total of 315 children (136 boys) were assessed (age: 10.6 +/- 0.6 years old). Outcomes at baseline and follow-up (16-months) were CRF determined using a maximal cycle test and sedentary time and PA measured with accelerometers. Data were analysed by isotemporal substitution analyses estimating the effect of reallocating 30 min/day of sedentary time by light (LPA), moderate (MPA) and vigorous physical activity (VPA) on CRF. VPA was positively and significantly associated with CRF cross-sectional (beta = 0.026, p < 0.001) and prospectively (beta = 0.010, p < 0.001). Reallocating 30 min/day of sedentary time into VPA was positively cross-sectionally (beta = 0.780, p < 0.001) and prospectively (beta = 0.303, p < 0.05) associated with CRF. Conversely, relocating 30-minutes of sedentary time into 30 minutes of LPA and MPA was not associated with CRF. These results suggest that reallocating an equal amount of time from sedentary into VPA is cross-sectional and prospectively associated with a favourable CRF.

AB - The aim of this study was to define the acid-etching technique for bone samples embedded in polymethyl metacrylate (PMMA) in order to visualize the osteocyte lacuno-canalicular network (LCN) for scanning electron microscopy (SEM). Human jaw bone tissue samples (N = 18) were collected from the study population consisting of patients having received dental implant surgery. After collection, the bone samples were fixed in 70% ethanol and non-decalcified samples embedded routinely into polymethyl metacrylate (PMMA). The PMMA embedded specimens were acid-etched in either 9 or 37% phosphoric acid (PA) and prepared for SEM for further analysis. PMMA embedded bone specimens acid-etched by 9% PA concentration accomplishes the most informative and favorable visualization of the LCN to be observed by SEM. Etching of PMMA embedded specimens is recommendable to start with 30 s or 40 s etching duration in order to find the proper etching duration for the samples examined. Visualizing osteocytes and LCN provides a tool to study bone structure that reflects changes in bone metabolism and diseases related to bone tissue. By proper etching protocol of non-decalcified and using scanning electron microscope it is possible to visualize the morphology of osteocytes and the network supporting vitality of bone tissue.

AB - This study investigated whether a high-fructose (HFr) diet changes the morphology of seminiferous tubules (ST) in rats and resveratrol (RES) has a possible restoring effect in this sense. Fructose (30%; w/v) was administered to rats alone or together with RES (50 mg/L) in drinking water for 8 weeks. In the HFr group, destruction of the germinal epithelium led to the detection of immature germ cells in the lumen. HFr diet gave rise to a decrease in the ST diameters (p < 0.05), Johnsen's tubular biopsy score values (p < 0.001), and an increase in the apoptotic index (p < 0.05). Ultrastructurally, HFr feeding increased lipid accumulation (p < 0.01), mitochondrial damage, and acrosomal abnormalities in spermatogenic cells. Treatment of HFr -fed rats with RES improved the reduced ST diameters and overall general histological and ultrastructural abnormalities of the STs, but did not change the increased apoptotic index.

AB - Hypothesis testing using a frequentist approach is the mainstay of biostatistics and forms the foundation for assessing the significance of study results. This classical method has well-understood advantages as it determines whether data are statistically improbable and provides a threshold (ie, the P value) for delineating significance. Alternative statistical approaches have been proposed, including Bayesian analysis. This technique incorporates a prior probability as to what is already known clinically with the observed data. It is important for otolaryngologists to understand the advantages and disadvantages of these 2 approaches to conduct the most appropriate analyses. PMID- 29192853 TI - To P or Not to P: Backing Bayesian Statistics. AB - In biomedical research, it is imperative to differentiate chance variation from truth before we generalize what we see in a sample of subjects to the wider population. For decades, we have relied on null hypothesis significance testing, where we calculate P values for our data to decide whether to reject a null hypothesis. This methodology is subject to substantial misinterpretation and errant conclusions. Instead of working backward by calculating the probability of our data if the null hypothesis were true, Bayesian statistics allow us instead to work forward, calculating the probability of our hypothesis given the available data. This methodology gives us a mathematical means of incorporating our "prior probabilities" from previous study data (if any) to produce new "posterior probabilities." Bayesian statistics tell us how confidently we should believe what we believe. It is time to embrace and encourage their use in our otolaryngology research. PMID- 29192855 TI - Early outcomes after intrathecal baclofen therapy in ambulatory patients with multiple sclerosis. AB - OBJECTIVE: Multiple sclerosis (MS) is a chronic autoimmune disease that causes demyelination and axonal loss. Walking difficulties are a common and debilitating symptom of MS; they are usually caused by spastic paresis of the lower extremities. Although intrathecal baclofen (ITB) therapy has been reported to be an effective treatment for spasticity in MS, there is limited published evidence regarding its effects on ambulation. The goal of this study was to characterize ITB therapy outcomes in ambulatory patients with MS. METHODS: Data from 47 ambulatory patients with MS who received ITB therapy were analyzed retrospectively. Outcome measures included Modified Ashworth Scale, Spasm Frequency Scale, Numeric Pain Rating Scale, and the Timed 25-Foot Walk. Repeated measures ANOVA was used to test for changes in outcome measures between baseline and posttreatment (6 months and 1 year). Significance was set at p < 0.05. Descriptive data are expressed as the mean +/- SD, and results of the repeated measures ANOVA tests and the Wilcoxon rank-sum test are expressed as the mean +/- SEM. RESULTS: There was a statistically significant reduction in the following variables: 1) aggregate lower-extremity Modified Ashworth Scale scores (from 14.8 +/- 1.0 before ITB therapy to 5.8 +/- 0.8 at 6 months posttreatment and 6.4 +/- 0.9 at 1 year [p < 0.05]); 2) Numeric Pain Rating Scale scores (4.4 +/- 0.5 before ITB, 2.8 +/- 0.5 at 6 months, and 2.4 +/- 0.4 at 1 year [p < 0.05]); 3) spasm frequency (45.7% of the patients reported a spasm frequency of >= 1 event per hour before ITB therapy, whereas 15.6% and 4.3% of the patients reported the same at 6 months and 1 year posttreatment, respectively [p < 0.05]); and 4) the number of oral medications taken for spasticity (p < 0.05). Of the 47 patients, 34 remained ambulatory at 6 months, and 32 at 1 year posttreatment. There was no statistically significant change in performance on the Timed 25-Foot Walk test over time for those patients who remained ambulatory. CONCLUSIONS: In this retrospective study, the authors found that ITB therapy is effective in reducing spasticity and related symptoms in ambulatory patients with MS. Because the use of ITB therapy is increasing in ambulatory patients with MS, randomized, prospective studies are important to help provide a more useful characterization of the effects of ITB therapy on ambulation. PMID- 29192856 TI - Management of antiplatelet therapy in patients undergoing neuroendovascular procedures. AB - Neuroendovascular techniques for treating cerebral aneurysms and other cerebrovascular pathology are increasingly becoming the standard of care. Intraluminal stents, aneurysm coils, and other flow diversion devices typically require concomitant antiplatelet therapy to reduce thromboembolic complications. The variability inherent with the pharmacodynamic response to common antiplatelet agents such as aspirin and clopidogrel complicates optimal selection of antiplatelet agents by clinicians. This review serves to discuss the literature related to antiplatelet use in neuroendovascular procedures and provides recommendations for clinicians on how to approach patients with variable response to antiplatelet agents, particularly clopidogrel. PMID- 29192857 TI - Knowledge silos: assessing knowledge sharing between specialties through the vestibular schwannoma literature. AB - OBJECTIVE It is common for a medical disorder to be managed or researched by individuals who work within different specialties. It is known that both neurosurgeons and neurotologists manage vestibular schwannoma (VS) patients. While overlap in specialty focus has the potential to stimulate multidisciplinary collaboration and innovative thinking, there is a risk of specialties forming closed-communication loops, called knowledge silos, which may inhibit knowledge diffusion. This study quantitatively assessed knowledge sharing between neurosurgery and otolaryngology on the subject of VS. METHODS A broad Web of Science search was used to download details for 4439 articles related to VS through 2016. The publishing journal's specialty and the authors' specialties (based on author department) were determined for available articles. All 114,647 of the article references were categorized by journal specialty. The prevalence of several VS topics was assessed using keyword searches of titles. RESULTS For articles written by neurosurgeons, 44.0% of citations were from neurosurgery journal articles and 23.4% were from otolaryngology journals. The citations of otolaryngology authors included 11.6% neurosurgery journals and 56.5% otolaryngology journals. Both author specialty and journal specialty led to more citations of the same specialty, though author specialty had the largest effect. Comparing the specialties' literature, several VS topics had significantly different levels of coverage, including radiosurgery and hearing topics. Despite the availability of the Internet, there has been no change in the proportions of references for either specialty since 1997 (the year PubMed became publicly available). CONCLUSIONS Partial knowledge silos are observed between neurosurgery and otolaryngology on the topic of VS, based on the peer-reviewed literature. The increase in access provided by the Internet and searchable online databases has not decreased specialty reference bias. These findings offer lessons to improve cross-specialty collaboration, physician learning, and consensus building. PMID- 29192858 TI - Head-up display may facilitate safe keyhole surgery for cerebral aneurysm clipping. AB - OBJECTIVE: The head-up display (HUD) is a modern technology that projects images or numeric information directly into the observer's sight line. Surgeons will no longer need to look away from the surgical view using the HUD system to confirm the preoperative or navigation image. The present study investigated the usefulness of the HUD system for performing cerebral aneurysm clipping surgeries. METHODS: Thirty-five patients underwent clipping surgery, including 20 keyhole surgeries for unruptured cerebral aneurysm, using the HUD system. Image information of structures such as the skull, cerebral vasculature, and aneurysm was integrated by the navigation software and linked with the positional coordinates of the microscope field of view. "Image injection" allowed visualization of the main structures that were concurrently tracked by the navigation image, and "closed shutter" switched the microscope field of view and the pointer image of the 3D brain image. RESULTS: The HUD system was effective for estimating the location and 3D anatomy of the aneurysm before craniotomy or dural opening in most patients. Scheduled keyhole minicraniotomy and opening of the sylvian fissure or partial rectal gyrus resection were performed on the optimized location with a minimum size in 20 patients. CONCLUSIONS: The HUD images superimposed on the microscope field of view were remarkably useful for less invasive and more safe aneurysm clipping and, in particular, keyhole clipping. PMID- 29192859 TI - Chemical venous thromboembolism prophylaxis in neurosurgical patients: an updated systematic review and meta-analysis. AB - OBJECTIVE: Venous thromboembolism (VTE) is a common and potentially life threatening complication. The risk of serious hemorrhagic complications when starting chemical prophylaxis for VTE prevention is a substantial concern for neurosurgeons. The objective of this study was to perform an updated systematic review and meta-analysis to determine if the rates of VTE and bleeding complications are different in patients undergoing chemoprophylaxis compared with placebo or mechanical prophylaxis alone following cranial or spinal procedures. METHODS: In February 2016 a systematic literature review was performed identifying 3944 articles from 4 different databases. A random-effects meta analysis was performed after identifying the articles that met inclusion criteria. RESULTS: Nine articles that met the inclusion criteria were included. The quality of the studies was good, with all of them being classified as Level 2 evidence, with moderate Jadad scores. A meta-analysis comparing chemoprophylaxis with placebo in the prevention of deep venous thrombosis showed a significant benefit to chemical prophylaxis (OR 0.51, 95% CI 0.37-0.71; p < 0.0001). No significant increase in major intracranial hemorrhage (p = 0.60), major extracranial hemorrhage (p = 0.98), or minor bleeding complications (p = 0.60) was found. CONCLUSIONS: Based on moderate-to-good quality of evidence, chemoprophylaxis is beneficial in preventing VTE, with no significant increase in either major or minor bleeding complications in patients undergoing cranial and spinal procedures. Further research is needed to determine whether this conclusion holds true for more specific subpopulations. PMID- 29192860 TI - Delayed cyst formation after stereotactic radiosurgery for brain arteriovenous malformations. AB - OBJECTIVE: Stereotactic radiosurgery (SRS) is a commonly employed treatment modality for brain arteriovenous malformations (AVMs). However, due to the low frequency of delayed cyst formation after AVM SRS, as well as the prolonged time interval between treatment and its occurrence, the characteristics of post-SRS cyst formation are not well defined. Therefore, the aims of this retrospective cohort study are to determine the rate of cyst formation after SRS for AVMs, identify predictive factors, and evaluate the clinical sequelae of post-SRS cysts. METHODS: The authors analyzed an SRS database for AVM patients who underwent SRS at the University of Virginia and identified those who developed post-SRS cysts. Statistical analyses were performed to determine predictors of post-SRS cyst formation and the effect of cyst formation on new or worsening seizures after SRS. RESULTS: The study cohort comprised 1159 AVM patients treated with SRS; cyst formation occurred in 17 patients (post-SRS cyst rate of 1.5%). Compared with patients who did not develop post-SRS cysts, those with cyst formation were treated with a greater number of radiosurgical isocenters (mean 3.8 vs 2.8, p = 0.047), had a longer follow-up (mean 132 vs 71 months, p < 0.001), were more likely to develop radiological radiation-induced changes (RIC) (64.7% vs 36.1%, p = 0.021), and had a longer duration of RIC (57 vs 21 months, p < 0.001). A higher number of isocenters (p = 0.014), radiological RIC (p = 0.002), and longer follow-up (p = 0.034) were found to be independent predictors of post-SRS cyst formation in the multivariate analysis. There was a trend toward a significant association between cyst formation and new or worsening seizures in univariate analysis (p = 0.054). CONCLUSIONS: Patients with greater nidal complexity appear to be more prone to post-SRS cyst formation. The findings of this study emphasize the importance of long-term follow-up for patients who have undergone AVM SRS, even after nidal obliteration is achieved. Post-SRS cysts may be epileptogenic, although seizure outcomes after AVM SRS are multifactorial. PMID- 29192861 TI - Ectopic brain tissue in the trigeminal nerve presenting as rapid-onset trigeminal neuralgia: case report. AB - The authors report the case of a 52-year-old man who presented with rapid-onset lancinating facial pain consistent with trigeminal neuralgia. Magnetic resonance imaging revealed a nonenhancing small lesion on the right trigeminal nerve concerning for an atypical schwannoma or neuroma. The patient underwent resection of the mass via a right retrosigmoid approach. His facial pain completely resolved immediately postoperatively and had not recurred at 6 months after surgery. The mass was consistent with normal brain tissue (neurons and glial cells) without evidence of mitoses. A final histopathological diagnosis of ectopic brain tissue with neural tissue demonstrating focal, chronic T-cell inflammation was made. The partial rhizotomy during resection was curative for the facial pain. To the authors' knowledge, this is the first report of neuroglial ectopia causing trigeminal neuralgia. PMID- 29192862 TI - Clinicoradiological features of intraneural perineuriomas obviate the need for tissue diagnosis. AB - OBJECTIVE: This study aimed to define a set of clinicoradiological parameters with a high specificity for the diagnosis of intraneural perineurioma, obviating the need for operative tissue diagnosis. METHODS: The authors retrospectively reviewed MR images obtained in a large cohort of patients who underwent targeted fascicular biopsy and included only those patients for whom the biopsy yielded a diagnosis. Clinical and radiological findings were then tested for their ability to predict a tissue diagnosis of intraneural perineurioma. The authors propose a new set of diagnostic criteria, referred to as the Perineurioma Diagnostic Criteria. The sensitivity, specificity, positive predictive value, and negative predictive value of several clinicoradiological methods of diagnosis were compared. RESULTS: A total of 195 patients who underwent targeted fascicular biopsy were included in the cohort, of whom 51 had a tissue diagnosis of intraneural perineurioma. When the clinicoradiological methods used in this study were compared, the highest sensitivity (0.86), negative predictive value (0.95), and F1 score (0.88) were observed for the decision trees generated in C5.0 and rPart, whereas the highest specificity (1.0) and positive predictive value (1.0) were observed for the Perineurioma Diagnostic Criteria. CONCLUSIONS: This study identified clinical and radiological features that are associated with a diagnosis of perineurioma. The Perineurioma Diagnostic Criteria were determined to be the following: 1) no cancer history, 2) unifocal disease, 3) moderate to severe hyperintensity on T2-weighted MR images, 4) moderate to severe contrast enhancement, 5) homogeneous contrast enhancement, 6) fusiform shape, 7) enlargement of the involved nerves, and 8) age <= 40 years. Use of the Perineurioma Diagnostic Criteria obviates the need for tissue diagnosis when all of the criteria are satisfied. PMID- 29192864 TI - Letter to the Editor.

PMID- 29192863 TI - Precipitating hydrophobic injectable liquid embolization of intracranial vascular shunts: initial experience and technical note. AB - Precipitating hydrophobic injectable liquid (PHIL) is a newly available liquid embolic agent for endovascular therapy. It is nonadhesive and composed of a biocompatible polymer dissolved in dimethyl sulfoxide solvent and bonded covalently with iodine. In this report, the authors present their preliminary experience using PHIL in the treatment of intracranial vascular shunts. Between July 2015 and December 2015, 11 patients underwent endovascular embolization using the PHIL embolic agent. Five patients had arteriovenous malformations, 4 had dural arteriovenous fistulas, 1 patient had a carotid-cavernous fistula, and 1 patient had a pial arteriovenous fistula. Clinical features, angioarchitectural characteristics, procedural details, and periprocedural complications were included in the analysis. Complete or near-complete obliteration of the nidus or fistulas was achieved in 8 of these patients. Partial embolization (approximately 80% in 2 and 30% in 1) was attained in the other 3 patients. Satisfactory venous penetration after nidal embolization was achieved in all patients. In 1 patient, the microcatheter could not be retrieved. No other major complications related to PHIL injection were noted during the procedure or periprocedural period. Clinical follow-up ranging from 8 months to 1 year showed good outcomes in all but 1 patient, who experienced an intraventricular hemorrhage 6 weeks after embolization. PHIL appears to be an effective alternative embolic material with certain advantages over other available liquid embolic agents. Further studies with adequate follow-up are required to fully evaluate its safety and efficacy. PMID- 29192865 TI - Electrocorticography and the early maturation of high-frequency suppression within the default mode network. AB - OBJECTIVE The acquisition and refinement of cognitive and behavioral skills during development is associated with the maturation of various brain oscillatory activities. Most developmental investigations have identified distinct patterns of low-frequency electrophysiological activity that are characteristic of various behavioral milestones. In this investigation, the authors focused on the cross sectional developmental properties of high-frequency spectral power from the brain's default mode network (DMN) during goal-directed behavior. METHODS The authors contrasted regionally specific, time-evolving high gamma power (HGP) in the lateral DMN cortex between 3 young children (age range 3-6 years) and 3 adults by use of electrocorticography (ECoG) recordings over the left perisylvian cortex during a picture-naming task. RESULTS Across all participants, a nearly identical and consistent response suppression of HGP, which is a functional signature of the DMN, was observed during task performance recordings acquired from ECoG electrodes placed over the lateral DMN cortex. This finding provides evidence of relatively early maturation of the DMN. Furthermore, only HGP relative to evoked alpha and beta band power showed this level of consistency across all participants. CONCLUSIONS Regionally specific, task-evoked suppression of the high-frequency components of the cortical power spectrum is established early in brain development, and this response may reflect the early maturation of specific cognitive and/or computational mechanisms. PMID- 29192866 TI - Frontoethmoidal meningoencephalocele: appraisal of a craniofacial surgical teaching program in Cambodia. AB - OBJECTIVE The treatment of frontoethmoidal meningoencephaloceles (fMECs) in Cambodia was not possible before the development of a program that taught some Khmer surgeons (working at the Children's Surgical Centre in Phnom Penh) how to surgically correct these deformities without any foreign help. The results of that teaching program are discussed in this paper. METHODS Between 2004 and 2009, both local and visiting foreign neurosurgical and craniofacial surgeons (the visitors coming twice a year) worked together to operate on 200 patients, and a report on those cases was published in 2010. In subsequent years (2010-2016), the Khmer surgeons operated on 100 patients without the presence of the visiting surgeons. In this study, the authors compare the second case series with the previously published series and the literature in terms of results and complications. The operations were performed with limited surgical materials and equipment, using a combined bicoronal and transfacial approach in most cases. Most of the patients came from very poor families. RESULTS Organizing the postoperative follow-up of these low-income patients (mean age 12 years) was probably the most challenging part of this teaching program. Nine of the patients were lost to surgical follow-up. In the other cases, cosmetic results were judged by the surgeons as worse than the patient's preoperative appearance in 1 case, poor in 12 cases, average in 27, and good in 51-data that are significantly less encouraging than the results reported by the joint local/visiting teams in 2010 (p = 0.0001). Nevertheless, patients and parents tended to have a better overall opinion about the surgical results (rating the results as good in 84% of the 80 cases in which parent or patient ratings were available). Twenty postoperative complications were observed (the most common being temporary CSF leaks). The rate of immediate postoperative complications directly related to fMEC surgery was less than that in the previous series, but the difference was not statistically significant (20% vs 28.5%, p = 0.58). No death was noted in this case series (in contrast to the previous series). Social questionnaire results confirmed that fMEC correction partially improved the adverse social and educational consequences of fMEC in affected children. CONCLUSIONS In the current state of this program, the local surgeons are able to correct fMECs in their own country, without foreign assistance, with good results in a majority of patients. Such humanitarian teaching programs generally take years to achieve the initial aims. PMID- 29192867 TI - Reduction of hyperthermia in pediatric patients with severe traumatic brain injury: a quality improvement initiative. AB - OBJECTIVE Severe traumatic brain injury remains a leading cause of morbidity and mortality in the pediatric population. Providers focus on reducing secondary brain injury by avoiding hypoxemia, avoiding hypotension, providing normoventilation, treating intracranial hypertension, and reducing cerebral metabolic demand. Hyperthermia is frequently present in patients with severe traumatic brain injury, contributes to cerebral metabolic demand, and is associated with prolonged hospital admission as well as impaired neurological outcome. The objective of this quality improvement initiative was to reduce the duration of hyperthermia for pediatric patients with severe traumatic brain injury during the initial 72 hours of admission to the pediatric intensive care unit. METHODS A retrospective chart review was performed to evaluate the incidence and duration of hyperthermia within a preintervention cohort. The retrospective phase was followed by three 6-month intervention periods (intervention Phase 1, the maintenance phase, and intervention Phase 2). Intervention Phase 1 entailed placement of a cooling blanket on the bed prior to patient arrival and turning it on once the patient's temperature rose above normothermia. The maintenance phase focused on sustaining the results of Phase 1. Intervention Phase 2 focused on total prevention of hyperthermia by initiating cooling blanket use immediately upon patient arrival to the intensive care unit. RESULTS The median hyperthermia duration in the preintervention cohort (n = 47) was 135 minutes. This was reduced in the Phase 1 cohort (n = 9) to 45 minutes, increased in the maintenance phase cohort (n = 6) to 88.5 minutes, and decreased again in the Phase 2 cohort (n = 9) to a median value of 0 minutes. Eight percent of patients in the intervention cohorts required additional sedation to tolerate the cooling blanket. Eight percent of patients in the intervention cohorts became briefly hypothermic while on the cooling blanket. No patient required neuromuscular blockade to tolerate the cooling blanket, experienced an arrhythmia, had new coagulopathy, or developed a pressure ulcer. CONCLUSIONS The placement of a cooling blanket on the bed prior to patient arrival and actively targeting normothermia successfully reduced the incidence and duration of hyperthermia with minimal adverse events. PMID- 29192868 TI - Bullough's bump: unusual protuberant fibro-osseous tumor of the temporal bone. Case report. AB - Scalp and calvarial masses are common in children and the differential diagnosis is broad. The authors recently cared for a child with an unusual fibro-osseous lesion of the temporal bone that has previously not been described in the pediatric neurosurgery literature. A 10-year-old girl presented with a firm, slowly enlarging protuberant mass arising from the squamous suture of the temporal bone without intracranial extension. The mass was removed en bloc through a temporal craniectomy and cranioplasty was performed. The patient had a smooth postoperative course. Histological examination showed multiple oval osseous islands dispersed throughout a bland fibrous stroma. The pathological diagnosis was "Bullough's bump," a rare, benign fibro-osseous neoplasm first described in 1999, and only 8 reported cases appear in the literature.

AB - OBJECTIVE Oligodendroglioma is a rare primary CNS neoplasm in the pediatric population, and only a limited number of studies in the literature have characterized this entity. Existing studies are limited by small sample sizes and discrepant interstudy findings in identified prognostic factors. In the present study, the authors aimed to increase the statistical power in evaluating for potential prognostic factors of pediatric oligodendrogliomas and sought to reconcile the discrepant findings present among existing studies by performing an individual-patient-data (IPD) meta-analysis and using multiple imputation to address data not directly available from existing studies. METHODS A systematic search was performed, and all studies found to be related to pediatric oligodendrogliomas and associated outcomes were screened for inclusion. Each study was searched for specific demographic and clinical characteristics of each patient and the duration of event-free survival (EFS) and overall survival (OS). Given that certain demographic and clinical information of each patient was not available within all studies, a multivariable imputation via chained equations model was used to impute missing data after the mechanism of missing data was determined. The primary end points of interest were hazard ratios for EFS and OS, as calculated by the Cox proportional-hazards model. Both univariate and multivariate analyses were performed. The multivariate model was adjusted for age, sex, tumor grade, mixed pathologies, extent of resection, chemotherapy, radiation therapy, tumor location, and initial presentation. A p value of less than 0.05 was considered statistically significant. RESULTS A systematic search identified 24 studies with both time-to-event and IPD characteristics available, and a total of 237 individual cases were available for analysis. A median of 19.4% of the values among clinical, demographic, and outcome variables in the compiled 237 cases were missing. Multivariate Cox regression analysis revealed subtotal resection (p = 0.007 [EFS] and 0.043 [OS]), initial presentation of headache (p = 0.006 [EFS] and 0.004 [OS]), mixed pathologies (p = 0.005 [EFS] and 0.049 [OS]), and location of the tumor in the parietal lobe (p = 0.044 [EFS] and 0.030 [OS]) to be significant predictors of tumor progression or recurrence and death. CONCLUSIONS The use of IPD meta-analysis provides a valuable means for increasing statistical power in investigations of disease entities with a very low incidence. Missing data are common in research, and multiple imputation is a flexible and valid approach for addressing this issue, when it is used conscientiously. Undergoing subtotal resection, having a parietal tumor, having tumors with mixed pathologies, and suffering headaches at the time of diagnosis portended a poorer prognosis in pediatric patients with oligodendroglioma.

AB - We explore the idea that cognitive demands of the handwriting would influence the degree of automaticity of the handwriting process, which in turn would affect the geometric parameters of texts. We compared the heterogeneity of handwritten texts in tasks with different cognitive demands; the heterogeneity of texts was analyzed with lacunarity, a measure of geometrical invariance. In Experiment 1, we asked participants to perform two tasks that varied in cognitive demands: transcription and exposition about an autobiographical episode. Lacunarity was significantly lower in transcription. In Experiment 2, we compared a veridical and a fictitious version of a personal event. Lacunarity was lower in veridical texts. We contend that differences in lacunarity of handwritten texts reveal the degree of automaticity in handwriting.

AB - Human figure drawing tasks such as the Draw-a-Person test have long been used to assess intelligence (F. Goodenough, 1926). The authors investigate the skills tapped by drawing and the risk factors associated with poor drawing. Self portraits of 345 preschool children were scored by raters trained in using the Draw-a-Person Intellectual Ability test (DAP:IQ) rubric (C. R. Reynolds & J. A. Hickman, 2004). Analyses of children's fine motor, gross motor, social, cognitive, and language skills revealed that only fine motor skill was an independent predictor of DAP:IQ scores. Being a boy and having a low birth weight were associated with lower DAP:IQ scores. These findings suggest that although the DAP:IQ may not be a valid measure of cognitive ability, it may be a useful screening tool for fine motor disturbances in at-risk children, such as boys who were born at low birth weights. Furthermore, researchers who use human figure drawing tasks to measure intelligence should measure fine motor skill in addition to intelligence. PMID- 29192872 TI - Experience of Being Young With Psoriasis: Self-Management Support Needs. AB - Psoriasis is a long-term condition with a possibly cumulative life course impairment. Young people struggle to minimize its effects on appearance and functioning. To date, the self-management needs of adolescents suffering from psoriasis have been underinvestigated. Using focus groups and individual interviews, we present an interpretive description of young people's experiences of living with psoriasis, the challenges they face, and the support they need to relieve suffering and come to terms with their condition. This process is characterized by loneliness, the self-imposition of limitations, and the lack of personalized knowledge and communication skills to manage the impact of disease and society's reactions. Our study provides insight into needs of early interventions tailored to address condition, role, and emotional management, involving parent education, peer support, storytelling, and roles for professionals. We argue that further research should involve young people, their parents, and professionals in the development and evaluation of interventions. PMID- 29192873 TI - Incidence of first stroke and ethnic differences in stroke pattern in Bradford, UK: Bradford Stroke Study. AB - Background Information on ethnic disparities in stroke between White and Pakistani population in Europe is scarce. Bradford District has the largest proportion of Pakistani people in England; this provides a unique opportunity to study the difference in stroke between the two major ethnic groups. Aim To determine the first-ever-stroke incidence and examine the disparities in stroke patterns between Whites and Pakistanis in Bradford. Methods Prospective 12 months study consisting of 273,327 adults (>=18 years) residents. Stroke cases were identified by multiple overlapping approaches. Results In the study period, 541 first-ever-strokes were recorded. The crude incidence rate was 198 per 100,000 person-years. Age adjusted-standardized rate to the World Health Organization world population of first-ever-stroke is 155 and 101 per 100,000 person-years in Pakistanis and Whites respectively. Four hundred and thirty-eight patients (81%) were Whites, 83 (15.3%) were Pakistanis, 11 (2%) were Indian and Bangladeshis, and 9 (1.7%) were of other ethnic origin. Pakistanis were significantly younger and had more obesity ( p = 0.049), and diabetes mellitus (DM) ( p = <0.001). They were less likely to suffer from atrial fibrillation ( p = <0.001), be ex- or current smokers ( p = <0.001), and drink alcohol above the recommended level ( p = 0.007) compared with Whites. In comparison with Whites, higher rates of age adjusted stroke (1.5-fold), lacunar infarction (threefold), and ischemic infarction due to large artery disease (twofold) were found in the Pakistanis. Conclusions The incidence of first-ever-stroke is higher in the Pakistanis compared with the Whites in Bradford, UK. Etiology and vascular risk factors vary between the ethnic groups. This information should be considered when investigating stroke etiology, and when planning prevention and care provision to improve outcomes after stroke. PMID- 29192874 TI - Young Children's ability to Discriminate between Antisocial and Prosocial Teases. AB - The present study was designed to (a) examine 5- to 8-year-old children's ability to discriminate between antisocial and prosocial teases and (b) determine whether their age and experiences within the home are associated with their ability to recognize these two types of teases. Results revealed that the 5- to 8-year-old children were able to discriminate between antisocial and prosocial teases. Although the children's parents or legal guardians indicated that the children had more frequent experience with prosocial than antisocial teases in the home, (a) the children were better able to correctly identify the intent of antisocial teasers than prosocial teasers and (b) the parents or legal guardians (correctly) indicated that their child would be better able to recognize an antisocial tease than a prosocial tease. Despite the finding that the children's comprehension of antisocial teasing tended to exceed their comprehension of prosocial teasing, the findings indicate that being relatively young (i.e., 5-6 years old vs. 7-8 years old) and having relatively frequent experience with antisocial teasing in the home may be associated with some children's difficulty in recognizing the intent behind antisocial teases. PMID- 29192875 TI - Circumferential dural resection technique and reconstruction for the removal of giant calcified transdural herniated thoracic discs. AB - OBJECTIVE The authors report a novel paradigm for resection of the disc or dural complex to treat giant calcified transdural herniated thoracic discs, and they describe a technique for the repair of dural defects. These herniated thoracic discs are uncommon, complicated lesions that often require a multidisciplinary team for effective treatment. The intradural component must be removed to effectively decompress the spinal cord. The opening of the friable dura mater, which frequently adheres to the extradural component of the disc, can result in large defects and difficult-to-manage CSF leaks. METHODS The authors performed a retrospective study of the technique and outcomes in patients with a transdural herniated disc treated at St. Joseph's Hospital and Medical Center within a 4 year period between 2012 and 2015. RESULTS During the study period, 7 patients (mean age 56.1 years) presented to the department of neurosurgery with clinical symptoms consistent with myeloradiculopathy. In all cases, 2-level corpectomies of the involved levels were combined with circumferential resection of the dura and complete decompression of the spinal cord. The dural defect was repaired with an onlay dural patch, and a large piece of AlloDerm (LifeCell Corp) graft was sewn to close the pleural defect. Every patient had a perioperative lumbar drain placed for CSF diversion. No patient suffered neurological decline related to the surgery, and 3 patients experienced clinically significant improvement in function. Two patients developed an early postoperative CSF leak that required operative revision to oversew the defects. CONCLUSIONS This novel technique for decompression of the spinal cord by dural resection for the removal of giant calcified transdural herniated thoracic discs is safe and results in excellent decompression of the spinal cord. The technique becomes necessary when primary repair of the dura is not possible, and it can be used in cases in which the resection of pathology includes the dura. PMID- 29192876 TI - Posterior inferior cerebellar artery with an extradural origin from the V3 segment: higher incidence on the nondominant vertebral artery. AB - OBJECTIVE The posterior inferior cerebellar artery (PICA) and the vertebral artery (VA) often exhibit anatomical variations at the craniovertebral junction (CVJ). An example of this is the PICA originating extradurally from the V3 segment of the VA. To date, some cadaveric investigations have been reported, but the incidence and relationship of this variation to the VA and the atlas as observed on clinical imaging have not been discussed. This study evaluated the prevalence of PICAs originating from the V3 on CT scanning. Other variations of the atlas and VA were also analyzed. METHODS CT images from a series of 153 patients who underwent 3D CT angiography (CTA) were analyzed, and variations of the PICA, VA, and atlas were investigated. RESULTS A total of 142 patients (284 sides) were analyzed; 11 patients (7.2%) were excluded due to poor image quality. The most common VA variation was the PICA originating from V3 (9.5% of 284 sides), which was more frequently observed on the nondominant VA than the dominant VA (22.5% vs 6.25%, p = 0.0005). A VA with a PICA end was identified in 4 sides (1.4%), which is the same incidence as observed in the persistent first intersegmental VA (1.4%). VA fenestration was only found in 1 side (0.35%). Regarding the atlas, ponticulus posticus was observed in 24 sides (8.5%). There was no relationship between the incidence of ponticulus posticus and the variations of the VA. CONCLUSIONS A PICA originating from V3 was the most common VA variation at the CVJ and was more common on the nondominant VA. Three dimensional CTA is useful for the evaluation of this variance. Surgeons should be mindful of this variation during operations. PMID- 29192877 TI - Impact of body mass index on surgical outcomes, narcotics consumption, and hospital costs following anterior cervical discectomy and fusion. AB - OBJECTIVE Given the increasing prevalence of obesity, more patients with a high body mass index (BMI) will require surgical treatment for degenerative spinal disease. In previous investigations of lumbar spine pathology, obesity has been associated with worsened postoperative outcomes and increased costs. However, few studies have examined the association between BMI and postoperative outcomes following anterior cervical discectomy and fusion (ACDF) procedures. Thus, the purpose of this study was to compare surgical outcomes, postoperative narcotics consumption, complications, and hospital costs among BMI stratifications for patients who have undergone primary 1- to 2-level ACDF procedures. METHODS The authors retrospectively reviewed a prospectively maintained surgical database of patients who had undergone primary 1- to 2-level ACDF for degenerative spinal pathology between 2008 and 2015. Patients were stratified by BMI as follows: normal weight (< 25.0 kg/m2), overweight (25.0-29.9 kg/m2), obese I (30.0-34.9 kg/m2), or obese II-III (>= 35.0 kg/m2). Differences in patient demographics and preoperative characteristics were compared across the BMI cohorts using 1-way ANOVA or chi-square analysis. Multivariate linear or Poisson regression with robust error variance was used to determine the presence of an association between BMI category and narcotics utilization, improvement in visual analog scale (VAS) scores, incidence of complications, arthrodesis rates, reoperation rates, and hospital costs. Regression analyses were controlled for preoperative demographic and procedural characteristics. RESULTS Two hundred seventy-seven patients were included in the analysis, of whom 20.9% (n = 58) were normal weight, 37.5% (n = 104) were overweight, 24.9% (n = 69) were obese I, and 16.6% (n = 46) were obese II-III. A higher BMI was associated with an older age (p = 0.049) and increased comorbidity burden (p = 0.001). No differences in sex, smoking status, insurance type, diagnosis, presence of neuropathy, or preoperative VAS pain scores were found among the BMI cohorts (p > 0.05). No significant differences were found among these cohorts as regards operative time, intraoperative blood loss, length of hospital stay, and number of operative levels (p > 0.05). Additionally, no significant differences in postoperative narcotics consumption, VAS score improvement, complication rates, arthrodesis rates, reoperation rates, or total direct costs existed across BMI stratifications (p > 0.05). CONCLUSIONS Patients with a higher BMI demonstrated surgical outcomes, narcotics consumption, and hospital costs comparable to those of patients with a lower BMI. Thus, ACDF procedures are both safe and effective for all patients across the entire BMI spectrum. Patients should be counseled to expect similar rates of postoperative complications and eventual clinical improvement regardless of their BMI.

AB - The authors report the case of a patient who suffered a Jefferson fracture during a professional football game. The C-1 (atlas) fracture was widely displaced anteriorly, but the transverse ligament was intact. In an effort to enable a return to play and avoid intersegmental (C1-2) fusion, the patient underwent a transoral approach for open reduction and internal fixation of the fracture. The associated posterior ring fracture displacement widened after this procedure, and a subsequent posterior arthrodesis and fixation of the fracture site was performed 6 months later when the fracture failed to heal with rigid collar immobilization. The approach maintained the normal range of motion at the atlantoaxial and atlantooccipital joints, which would have been sacrificed by an atlantoaxial or occipitocervical fusion, as is traditionally performed. Ultimately, the patient decided not to return to the football field, but this approach could avoid the more significant loss of motion associated with atlantoaxial or occipitocervical fusion for unstable Jefferson fractures. PMID- 29192879 TI - Pedicle screw placement accuracy using ultra-low radiation imaging with image enhancement versus conventional fluoroscopy in minimally invasive transforaminal lumbar interbody fusion: an internally randomized controlled trial. AB - OBJECTIVE A previous study found that ultra-low radiation imaging (ULRI) with image enhancement significantly decreases radiation exposure by roughly 75% for both the patient and operating room personnel during minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) (p < 0.001). However, no clinical data exist on whether this imaging modality negatively impacts patient outcomes. Thus, the goal of this randomized controlled trial was to assess pedicle screw placement accuracy with ULRI with image enhancement compared with conventional, standard-dose fluoroscopy for patients undergoing single-level MIS TLIF. METHODS An institutional review board-approved, prospective internally randomized controlled trial was performed to compare breach rates for pedicle screw placement performed using ULRI with image enhancement versus conventional fluoroscopy. For cannulation and pedicle screw placement, surgery on 1 side (left vs right) was randomly assigned to be performed under ULRI. Screws on the opposite side were placed under conventional fluoroscopy, thereby allowing each patient to serve as his/her own control. In addition to standard intraoperative images to check screw placement, each patient underwent postoperative CT. Three experienced neurosurgeons independently analyzed the images and were blinded as to which imaging modality was used to assist with each screw placement. Screw placement was analyzed for pedicle breach (lateral vs medial and Grade 0 [< 2.0 mm], Grade 1 [2.0-4.0 mm], or Grade 2 [> 4.0 mm]), appropriate screw depth (50% 75% of the vertebral body's anteroposterior dimension), and appropriate screw angle (within 10 degrees of the pedicle angle). The effective breach rate was calculated as the percentage of screws evaluated as breached > 2.0 mm medially or postoperatively symptomatic. RESULTS Twenty-three consecutive patients underwent single-level MIS-TLIF, and their sides were randomly assigned to receive ULRI. No patient had immediate postoperative complications (e.g., neurological decline, need for hardware repositioning). On CT confirmation, 4 screws that had K-wire placement and cannulation under ULRI and screw placement under conventional fluoroscopy showed deviations. There were 2 breaches that deviated medially but both were Grade 0 (< 2.0 mm). Similarly, 2 breaches occurred that were Grade 1 (> 2.0 mm) but both deviated laterally. Therefore, the effective breach rate (breach > 2.0 mm deviated medially) was unchanged in both imaging groups (0% using either ULRI or conventional fluoroscopy; p = 1.00). CONCLUSIONS ULRI with image enhancement does not compromise accuracy during pedicle screw placement compared with conventional fluoroscopy while it significantly decreases radiation exposure to both the patient and operating room personnel.

AB - There is a paucity of literature describing the management of recurrent symptomatic postoperative epidural hematoma or uncontrollable intraoperative hemorrhage in posterior spine surgery. Traditional management with hematoma evacuation and wound closure over suction drains may not be effective in certain cases, and it can lead to recurrence and neurological injury. The authors report 3 cases of recurrent symptomatic postoperative epidural hematoma successfully managed with novel open-wound negative-pressure dressing therapy (NPDT), as well as 1 case of uncontrollable intraoperative hemorrhage that was primarily managed with the same technique. The 3 patients who developed a postoperative epidural hematoma became symptomatic 2-17 days after the initial operation. All 3 patients underwent at least 1 hematoma evacuation and wound closure over suction drains prior to recurrence with severe neurological deficit and definitive management with NPDT. One patient was managed primarily with NPDT for uncontrollable intraoperative hemorrhage during posterior cervical laminectomy. All 4 patients had significant risk factors for postoperative epidural hematoma. NPDT for 3-9 days with delayed wound closure was successful in all patients. The 3 patients with recurrent symptomatic postoperative epidural hematoma had significant improvement in their severe neurological deficit. None of the patients developed a postoperative wound infection, and none of the patients required transfusion due to NPDT. NPDT with delayed wound closure may be an option in certain patients, when wound closure over suction drains is unlikely to prevent further neurological injury.

AB - Repeated CT scans are known to increase the risk of cancer; thus, it is paradoxical to use multiple follow-up CT scans to monitor the development of a lung nodule and conduct early treatment of the nodule. In the case of a solitary lung nodule, regional scanning and region of interest (ROI) reconstruction are likely to restore the internal area at the nodule. A limited-range few-view CT is proposed in this paper for lung nodule follow-ups with extremely reduced X radiation. For a planned scanning of an ROI, where a solitary lung nodule is positioned, a limited-range few-view CT can be employed, and thus, less tissue is exposed to X-radiation per view. An ROI reconstruction method is also proposed that makes full use of the former standard lung scan. The experimental results show that the nodule size and shape are preserved. In the case of a 40-mm ROI, the number of exposed X-rays can be reduced by 99.6% for a circular scan and 99.9% for a 3-D scan. PMID- 29192885 TI - Robust Low-Dose CT Sinogram Preprocessing via Exploiting Noise-Generating Mechanism. AB - Computed tomography (CT) image recovery from low-mAs acquisitions without adequate treatment is always severely degraded due to a number of physical factors. In this paper, we formulate the low-dose CT sinogram preprocessing as a standard maximum a posteriori (MAP) estimation, which takes full consideration of the statistical properties of the two intrinsic noise sources in low-dose CT, i.e., the X-ray photon statistics and the electronic noise background. In addition, instead of using a general image prior as found in the traditional sinogram recovery models, we design a new prior formulation to more rationally encode the piecewise-linear configurations underlying a sinogram than previously used ones, like the TV prior term. As compared with the previous methods, especially the MAP-based ones, both the likelihood/loss and prior/regularization terms in the proposed model are ameliorated in a more accurate manner and better comply with the statistical essence of the generation mechanism of a practical sinogram. We further construct an efficient alternating direction method of multipliers algorithm to solve the proposed MAP framework. Experiments on simulated and real low-dose CT data demonstrate the superiority of the proposed method according to both visual inspection and comprehensive quantitative performance evaluation. PMID- 29192887 TI - A Feasibility Study of Low-Dose Single-Scan Dual-Energy Cone-Beam CT in Many-View Under-Sampling Framework. AB - A single-scan dual-energy low-dose cone-beam CT (CBCT) imaging technique that exploits a multi-slit filter is proposed in this paper. The multi-slit filter installed between the x-ray source and the scanned object is reciprocated during a scan. The x-ray beams through the slits would generate relatively low-energy x ray projection data, while the filtered beams would make high-energy projection data. An iterative image reconstruction algorithm that uses an adaptive-steepest descent method to minimize image total-variation under the constraint of data fidelity was applied to reconstructing the image from the low-energy projection data. Since the high-energy projection data suffer from a substantially high noise level due to the beam filtration, we have developed a new algorithm that exploits the joint sparsity between the low- and high-energy CT images for image reconstruction of the high-energy CT image. The proposed image reconstruction algorithm uses a gradient magnitude image (GMI) of the low-energy CT image by regularizing the difference of GMIs of the low- and high-energy CT images to be minimized. The feasibility of the proposed technique has been demonstrated by the use of various phantoms in the experimental CBCT setup. Furthermore, based on the proposed dual-energy imaging, a material differentiation was performed and its potential utility has been shown. The proposed imaging technique produced promising results for its potential application to a low-dose single-scan dual energy CBCT. PMID- 29192889 TI - Hydration water dynamics around a protein surface: a first passage time approach. AB - A stochastic noise-driven dynamic model is proposed to study the diffusion of water molecules around a protein surface, under the effect of thermal fluctuations that arise due to the collision of water molecules with the surrounding environment. The underlying dynamics of such a system may be described in the framework of the generalized Langevin equation, where the thermal fluctuations are assumed to be algebraically correlated in time, which governs the non-Markovian behavior of the system. Results of the calculations of mean-square displacement and the velocity autocorrelation function reveal that the hydration water around the protein surface follows subdiffusive dynamics at long times. Analytical expressions for the first passage time distribution, survival probability, mean residence time and mean first passage time of water molecules are derived for different boundary conditions, to analyze hydration water dynamics under the effect of thermally correlated noise. The results depict a unimodal distribution of the first passage time unlike Brownian motion. The survival probability of hydration water follows a stretched exponential decay for both boundary conditions. The mean residence time of the hydration water molecule for different initial positions increases with increase in the complexity/heterogeneity of the surrounding environment for both boundary conditions. The mean first passage time of the water molecule to reach the absorbing/reflecting boundary follows an asymptotic power law with respect to the thickness of the hydration layer, and increases with increase in the complexity/heterogeneity of the environment. PMID- 29192888 TI - Low-Dose CBCT Reconstruction Using Hessian Schatten Penalties. AB - Cone-beam computed tomography (CBCT) has been widely used in radiation therapy. For accurate patient setup and treatment target localization, it is important to obtain high-quality reconstruction images. The total variation (TV) penalty has shown the state-of-the-art performance in suppressing noise and preserving edges for statistical iterative image reconstruction, but it sometimes leads to the so called staircase effect. In this paper, we proposed to use a new family of penalties-the Hessian Schatten (HS) penalties-for the CBCT reconstruction. Consisting of the second-order derivatives, the HS penalties are able to reflect the smooth intensity transitions of the underlying image without introducing the staircase effect. We discussed and compared the behaviors of several convex HS penalties with orders 1, 2, and for CBCT reconstruction. We used the majorization minimization approach with a primal-dual formulation for the corresponding optimization problem. Experiments on two digital phantoms and two physical phantoms demonstrated the proposed penalty family's outstanding performance over TV in suppressing the staircase effect, and the HS penalty with order 1 had the best performance among the HS penalties tested. PMID- 29192890 TI - Van der Waals heterojunction diode composed of WS2 flake placed on p-type Si substrate. AB - P-N junctions represent the fundamental building blocks of most semiconductors for optoelectronic functions. This work demonstrates a technique for forming a WS2/Si van der Waals junction based on mechanical exfoliation. Multilayered WS2 nanoflakes were exfoliated on the surface of bulk p-type Si substrates using a polydimethylsiloxane stamp. We found that the fabricated WS2/Si p-n junctions exhibited rectifying characteristics. We studied the effect of annealing processes on the performance of the WS2/Si van der Waals p-n junction and demonstrated that annealing improved its electrical characteristics. However, devices with vacuum annealing have an enhanced forward-bias current compared to those annealed in a gaseous environment. We also studied the top-gate-tunable rectification characteristics across the p-n junction interface in experiments as well as density functional theory calculations. Under various temperatures, Zener breakdown occurred at low reverse-bias voltages, and its breakdown voltage exhibited a negative coefficient of temperature. Another breakdown voltage was observed, which increased with temperature, suggesting a positive coefficient of temperature. Therefore, such a breakdown can be assigned to avalanche breakdown. This work demonstrates a promising application of two-dimensional materials placed directly on conventional bulk Si substrates. PMID- 29192891 TI - Comparison of different functional EIT approaches to quantify tidal ventilation distribution. AB - OBJECTIVE: The aim of the study was to examine the pros and cons of different types of functional EIT (fEIT) to quantify tidal ventilation distribution in a clinical setting. APPROACH: fEIT images were calculated with (1) standard deviation of pixel time curve, (2) regression coefficients of global and local impedance time curves, or (3) mean tidal variations. To characterize temporal heterogeneity of tidal ventilation distribution, another fEIT image of pixel inspiration times is also proposed. MAIN RESULTS: fEIT-regression is very robust to signals with different phase information. When the respiratory signal should be distinguished from the heart-beat related signal, or during high-frequency oscillatory ventilation, fEIT-regression is superior to other types. fEIT-tidal variation is the most stable image type regarding the baseline shift. We recommend using this type of fEIT image for preliminary evaluation of the acquired EIT data. However, all these fEITs would be misleading in their assessment of ventilation distribution in the presence of temporal heterogeneity. SIGNIFICANCE: The analysis software provided by the currently available commercial EIT equipment only offers either fEIT of standard deviation or tidal variation. Considering the pros and cons of each fEIT type, we recommend embedding more types into the analysis software to allow the physicians dealing with more complex clinical applications with on-line EIT measurements.

AB - The nanostructuring of graphene into superlattices offers the possibility of tuning both the electronic and thermal properties of graphene. Using classical and quantum mechanical calculations, we have investigated the electronic and thermoelectric properties of the atomically thin superlattice of C3Si3/C (C3Ge3/C) formed by the incorporation of Si (Ge) atoms into graphene. The bandgap and phonon thermal conductivity of C3Si3/C (C3Ge3/C) are 0.54 (0.51) eV and 15.48 (12.64) Wm-1K-1, respectively, while the carrier mobility of C3Si3/C (C3Ge3/C) is 1.285 x 105 (1.311 x 105) cm2V-1s-1 at 300 K. The thermoelectric figure of merit for C3Si3/C (C3Ge3/C) can be optimized via the tuning of carrier concentration to obtain the prominent ZT value of 1.95 (2.72).

AB - Understanding the interfacial properties of catalyst/substrate is crucial for the design of high-performance catalyst for important chemical reactions. Recent years have witnessed a surge of research in utilizing MoS2 as a promising electro catalyst for hydrogen production, and field effect has been employed to enhance the activity (Adv. Mater. 2017, 29, 1604464; Nano Lett. 2017, 17, 4109). However, the underlying atomic mechanism remains unclear. In this paper, by using the prototype MoS2/Au system as a probe, we investigate effects of external electric field on the interfacial electronic structures via density functional theory (DFT) based first-principles calculations. Our results reveal that although there is no covalent interaction between MoS2 overlayer and Au substrate, an applied electric field efficiently adjusts the charge transfer between MoS2 and Au, leading to tunable Schottky barrier type (n-type to p-type) and decrease of barrier height to facilitate charge injection. Furthermore, we predict that the adsorption energy of atomic hydrogen on MoS2/Au to be readily controlled by electric field to a broad range within a modest magnitude of field, which may benefit the performance enhancement of hydrogen evolution reaction. Our DFT results provide valuable insight into the experimental observations and pave the way for future understanding and control of catalysts in practice, such as those with vacancies, defects, edge states or synthesized nanostructures.

AB - The research interest in photoelectrochemical (PEC) water splitting is ever growing due to its potential to contribute towards clean and portable energy. However, the lack of low energy band gap materials with high photocorrosion resistance is the primary setback inhibiting this technology from commercialisation. The ternary alloy InGaN shows promise to meet the photoelectrode material requirements due to its high chemical stability and band gap tunability. The band gap of InGaN can be modulated from the UV to IR regions by adjusting the In concentration so as to absorb the maximum portion of the solar spectrum. This paper reports on the influence of In concentration on the PEC properties of planar and nanopillar (NP) InGaN/GaN multi-quantum well (MQW) photoanodes, where NPs were fabricated using a top-down approach. Results show that changing the In concentration, while having a minor effect on the PEC performance of planar MQWs, has an enormous impact on the PEC performance of NP MQWs, with large variations in the photocurrent density observed. Planar photoanodes containing MQWs generate marginally lower photocurrents compared to photoanodes without MQWs when illuminated with sunlight. NP MQWs with 30% In generated the highest photocurrent density of 1.6 mA cm-2, 4 times greater than that of its planar counterpart and 1.8 times greater than that of the NP photoanode with no MQWs. The InGaN/GaN MQWs also slightly influenced the onset potential of both the planar and NP photoanodes. Micro-photoluminescence, diffuse reflectance spectroscopy and IPCE measurements are used to explain these results.

AB - The association between corals and photosynthetic dinoflagellates (Symbiodinium spp.) is the key to the success of reef ecosystems in highly oligotrophic environments, but it is also their Achilles' heel due to its vulnerability to local stressors and the effects of climate change. Research during the last two decades has shaped a view that coral host-Symbiodinium pairings are diverse, but largely exclusive. Deep sequencing has now revealed the existence of a rare diversity of cryptic Symbiodinium assemblages within the coral holobiont, in addition to one or a few abundant algal members. While the contribution of the most abundant resident Symbiodinium species to coral physiology is widely recognized, the significance of the rare and low abundant background Symbiodinium remains a matter of debate. In this study, we assessed how coral-Symbiodinium communities assemble and how rare and abundant components together constitute the Symbiodinium community by analyzing 892 coral samples comprising >110 000 unique Symbiodinium ITS2 marker gene sequences. Using network modeling, we show that host-Symbiodinium communities assemble in non-random 'clusters' of abundant and rare symbionts. Symbiodinium community structure follows the same principles as bacterial communities, for which the functional significance of rare members (the 'rare bacterial biosphere') has long been recognized. Importantly, the inclusion of rare Symbiodinium taxa in robustness analyses revealed a significant contribution to the stability of the host-symbiont community overall. As such, it highlights the potential functions rare symbionts may provide to environmental resilience of the coral holobiont. PMID- 29192902 TI - Relevance of the p53-MDM2 axis to aging. AB - In response to varying stress signals, the p53 tumor suppressor is able to promote repair, survival, or elimination of damaged cells - processes that have great relevance to organismal aging. Although the link between p53 and cancer is well established, the contribution of p53 to the aging process is less clear. Delineating how p53 regulates distinct aging hallmarks such as cellular senescence, genomic instability, mitochondrial dysfunction, and altered metabolic pathways will be critical. Mouse models have further revealed the centrality and complexity of the p53 network in aging processes. While naturally aged mice have linked longevity with declining p53 function, some accelerated aging mice present with chronic p53 activation, whose phenotypes can be rescued upon p53 deficiency. Further, direct modulation of the p53-MDM2 axis has correlated elevated p53 activity with either early aging or with delayed-onset aging. We speculate that p53-mediated aging phenotypes in these mice must have (1) stably active p53 due to MDM2 dysregulation or chronic stress or (2) shifted p53 outcomes. Pinpointing which p53 stressors, modifications, and outcomes drive aging processes will provide further insights into our understanding of the human aging process and could have implications for both cancer and aging therapeutics. PMID- 29192906 TI - Infrared spectroscopy of hydrated polycyclic aromatic hydrocarbon cations: naphthalene+-water. AB - Polycyclic aromatic hydrocarbons (PAHs) are suggested to occur in interstellar media and ice grains. It is important to characterize hydrated PAHs and their cations to explore their stability in interstellar and biological media. Herein, the infrared photodissociation (IRPD) spectrum of the naphthalene+-H2O radical cation (Np+-H2O) recorded in the O-H and C-H stretch range is analysed by dispersion-corrected density functional theory calculations at the B3LYP-D3/aug cc-pVTZ level to determine its structure and intermolecular bonding. Monohydration of Np+ in its 2Au ground electronic state leads to the formation of a bifurcated CHO ionic hydrogen bond (H-bond), in which the lone pairs of H2O bind to two adjacent CH proton donors of the two aromatic rings. The frequency dependent branching ratios observed for IRPD of cold Np+-H2O-Ar clusters allows the estimation of the dissociation energy of Np+-H2O as D0 ~ 2800 +/- 300 cm-1. The monohydration motif of Np+ differs qualitatively from that of the benzene cation in both structure and binding energy, indicating the strong influence of the multiple aromatic rings on the hydration of PAH+ cations. This difference is rationalized by natural bond orbital analysis of the ionic H-bond motif. Comparison with neutral Np-H2O reveals the large change in structure and bond strength of the hydrated PAHs upon ionization. While neutral Np-H2O is stabilized by weak pi H-bonds (OHpi, pi-stacking), strong cation-dipole forces favour a planar bifurcated CHO ionic H-bond in Np+-H2O. PMID- 29192904 TI - Specific substrate-driven changes in human faecal microbiota composition contrast with functional redundancy in short-chain fatty acid production. AB - The diet provides carbohydrates that are non-digestible in the upper gut and are major carbon and energy sources for the microbial community in the lower intestine, supporting a complex metabolic network. Fermentation produces the short-chain fatty acids (SCFAs) acetate, propionate and butyrate, which have health-promoting effects for the human host. Here we investigated microbial community changes and SCFA production during in vitro batch incubations of 15 different non-digestible carbohydrates, at two initial pH values with faecal microbiota from three different human donors. To investigate temporal stability and reproducibility, a further experiment was performed 1 year later with four of the carbohydrates. The lower pH (5.5) led to higher butyrate and the higher pH (6.5) to more propionate production. The strongest propionigenic effect was found with rhamnose, followed by galactomannans, whereas fructans and several alpha- and beta-glucans led to higher butyrate production. 16S ribosomal RNA gene-based quantitative PCR analysis of 22 different microbial groups together with 454 sequencing revealed significant stimulation of specific bacteria in response to particular carbohydrates. Some changes were ascribed to metabolite cross-feeding, for example, utilisation by Eubacterium hallii of 1,2-propanediol produced from fermentation of rhamnose by Blautia spp. Despite marked inter-individual differences in microbiota composition, SCFA production was surprisingly reproducible for different carbohydrates, indicating a level of functional redundancy. Interestingly, butyrate formation was influenced not only by the overall % butyrate-producing bacteria in the community but also by the initial pH, consistent with a pH-dependent shift in the stoichiometry of butyrate production. PMID- 29192905 TI - Microbial life on a sand grain: from bulk sediment to single grains. AB - Globally, marine surface sediments constitute a habitat for estimated 1.7 * 1028 prokaryotes. For benthic microbial community analysis, usually, several grams of sediment are processed. In this study, we made the step from bulk sediments to single sand grains to address the microbial community directly in its micro habitat: the individual bacterial diversity on 17 sand grains was analyzed by 16S ribosomal RNA gene sequencing and visualized on sand grains using catalyzed reporter deposition fluorescence in situ hybridization. In all, 104-105 cells were present on grains from 202 to 635 MUm diameter. Colonization was patchy, with exposed areas largely devoid of any epi-growth (mean cell-cell distance 4.5+/-5.9 MUm) and protected areas more densely populated (0.5+/-0.7 MUm). Mean cell-cell distances were 100-fold shorter compared with the water column. In general, growth occurred in monolayers. Each sand grain harbors a highly diverse bacterial community as shown by several thousand species-level operational taxonomic units (OTU)0.97. Only 4-8 single grains are needed to cover 50% of OTU0.97 richness found in bulk sediment. Although bacterial communities differed between sand grains, a core community accounting for >50% of all cells was present on each sand grain. The communities between sediment grains are more similar than between soil macroaggregates.

AB - The carbon K-shell (1s) X-ray photoelectron spectroscopy (XPS) and near-edge X ray absorption fine structure (NEXAFS) spectroscopy of the seven isolated pentagon-rule (IPR) isomers of fullerene C80 have been calculated by means of density functional theory (DFT) theoretically. We have demonstrated the relationship between molecular structures and related X-ray spectroscopies. The dependence of the XPS spectra on the structures of the seven C80 molecules is imperfect, while the NEXAFS spectra show strong dependence on the seven fullerene molecules, so the NEXAFS spectra can be employed to identify all of the studied isomers. The spectral components of different local environments have been explored in detail. PMID- 29192909 TI - The silane-methane dimer revisited: more than a dispersion-bound system? AB - We present here a comprehensive computational and theoretical analysis of the silane-methane dimer with the goal of understanding the origin of the interactions that hold it together and the factors that affect its strength. Several interaction topologies have been analysed and the associated interaction energies have been evaluated at the CCSD(T)/aug-cc-pVTZ level of theory. Next, substitution effects have been studied on several silane and methane derivatives. The molecular electrostatic potential (MEP) maps of the molecules involved in the interactions have been built to try to correlate the interaction energies with the maximum/minimum EP values (Vs). Furthermore, we have performed an energy decomposition analysis to gain deeper insight into the physical nature of the interactions and to unravel whether dispersion is the primary component of the attraction. Finally, we complete the theoretical analysis with the study of several experimental crystal structures in which there are silylmethyl short contacts. PMID- 29192908 TI - A spectroscopic study on the satellite vibronic band in phosphorescent Pt complexes with high colour purity. AB - To understand the relationship between the narrowing of an emission band and structural changes, we synthesised tetradentate Pt-complexes. Pt-1 has two directly connected carbazole (Cz) moieties, Pt-2 has two additional methyl groups to Pt-1, and Pt-3 has one Cz moiety. The absorption and emission spectra of Pt-2 were identical to those of Pt-1. Pt-3's emission was observed at a shorter wavelength compared to the others. We achieved phosphorescence with high colour purity by introducing a tetradentate ligand. All the Pt-complexes showed a vibronic structure in the emission spectra measured at 77 and 300 K. The 0-0 vibronic band of the Pt-complexes is quite intense compared to the 0-1 vibronic band, which may be due to less structural change of the fused tetradentate ligand in the excited state relative to the ground state. The spacing of the 0-0 and 1-0 vibronic bands is 1487 and 1323 cm-1, respectively. To understand the origin of the satellite vibronic bands, we carried out vibrational spectroscopic (IR and Raman) measurements and theoretical calculations to analyse the infrared spectrum. In addition, we carried out a transient Raman experiment to obtain the vibronic information of an excited Pt-1. The vibronic spacing in the emission was caused by the displacement of the potential energy curve in the excited state. The highest occupied molecular orbital is populated with a Cz moiety and the lowest unoccupied molecular orbital is localized at the terminal pyridine moiety. For the triplet state, however, the highest singly occupied molecular orbital is delocalized on the pyrazole or imidazole moiety, as well as the pyridine moiety. These groups are located at the terminal site of the ligand, and are less rigidified and more flexible. Therefore, the major origin of the satellite vibration band in emission spectra is the stretching of the terminal groups. PMID- 29192910 TI - Combined determination of copper ions and beta-amyloid peptide by a single ratiometric electrochemical biosensor. AB - Copper ions (Cu2+) play a critical role in biological processes and are directly involved in beta-amyloid peptide (Abeta) aggregation, which is responsible for the occurrence and development of Alzheimer's disease (AD). Therefore, combined determination of Cu2+ and Abeta in one analytical system is of great significance to understand the exact nature of the AD event. This work presents a novel ratiometric electrochemical biosensor for the dual determination of Cu2+ and Abeta1-42. This unique sensor is based on a 2,2'-azinobis-(3-ethylbenzothiazoline 6-sulphonate) (ABTS) and poly(diallyldimethylammonium chloride) (PDDA)-bi functionalized single-walled carbon nanotubes (ABTS-PDDA/CNTs) composite. The inclusion of ABTS not only enhanced the sensitivity, but it also acted as an inner reference molecule to improve detection accuracy. The specific recognition of Cu2+ was realized by neurokinin B (NKB) coatings on the ABTS-PDDA/CNTs surface to form a [CuII(NKB)2] complex with Cu2+. The ABTS-PDDA/CNTs-NKB modified electrode also displayed an excellent electrochemical response toward the Abeta1 42 monomer, when a certain amount of the Abeta1-42 monomer was added to Cu2+ contained PBS buffer, which was due to the release of Cu2+ from the [CuII(NKB)2] complex through Abeta binding to Cu2+. Meanwhile, our work showed that Cu2+ bound Abeta1-42 was concentration-dependent. Consequently, the presented electrochemical approach was capable of quantifying two important biological species associated with AD by one single biosensor, with the detection limits of 0.04 MUM for Cu2+ and 0.5 ng mL-1 for Abeta1-42, respectively. Finally, the ratiometric electrode was successfully applied for monitoring Cu2+ and Abeta1-42 variations in plasma and hippocampus of normal and AD rats. PMID- 29192911 TI - Reversible switching of the spin state in a manganese phthalocyanine molecule by atomic nitrogen. AB - Reversible control of the spin state of an organic molecule is significant for the development of molecular spintronic devices. Here, density functional theory calculations have been performed to study the adsorption of atomic nitrogen on a single manganese phthalocyanine (MnPc) molecule, three-layered MnPc, and MnPc on an Fe(100) surface. For all three cases, the N atom strongly adsorbs on top of the Mn atom and induces a significant variation of the geometric, electronic and magnetic properties. After N adsorption, an energy gap appears and the electronic states become unpolarized. Different functionals including three hybrid functionals are used in these calculations, and all yield a switchable spin state. PMID- 29192912 TI - Quantitative profiling of carbonyl metabolites directly in crude biological extracts using chemoselective tagging and nanoESI-FTMS. AB - The extensive range of chemical structures, wide range of abundances, and chemical instability of metabolites present in the metabolome pose major analytical challenges that are difficult to address with existing technologies. To address these issues, one approach is to target a subset of metabolites that share a functional group, such as ketones and aldehydes, using chemoselective tagging. Here we report a greatly improved chemoselective method for the quantitative analysis of hydrophilic and hydrophobic carbonyl-containing metabolites directly in biological samples. This method is based on direct tissue or cells extraction with simultaneous derivatization of stable and labile carbonylated metabolites using N-[2-(aminooxy)ethyl]-N,N-dimethyl-1 dodecylammonium (QDA) and 13CD3 labeled QDA. We combined innovations of direct quenching of biological sample with frozen derivatization conditions under the catalyst N,N-dimethyl-p-phenylenediamine, which facilitated the formation of oxime stable-isotope ion pairs differing by m/z 4.02188 while minimizing metabolite degradation. The resulting oximes were extracted by HyperSep C8 tips to remove interfering compounds, and the products were detected using nano electrospray ionization interfaced with a Thermo Fusion mass spectrometer. The quaternary ammonium tagging greatly increased electrospray MS detection sensitivity and the signature ions pairs enabled simple identification of carbonyl compounds. The improved method showed the lower limits of quantification for carbonyl standards to be in the range of 0.20-2 nM, with linearity of R2 > 0.99 over 4 orders of magnitude. We have applied the method to assign 66 carbonyls in mouse tumor tissues, many of which could not be assigned solely by accurate mass and tandem MS. Fourteen of the metabolites were quantified using authentic standards. We also demonstrated the suitability of this method for determining 13C labeled isotopologues of carbonyl metabolites in 13C6-glucose based stable isotope-resolved metabolomic (SIRM) studies.

PMID- 29192914 TI - Ab initio analysis on potential superbases of several hyperlithiated species: Li3F2O and Li3F2OHn (n = 1, 2). AB - A systematic investigation on the potential basicity of the novel hyperlithiated species Li3F2O and Li3F2(OH)n (n = 1, 2) based upon the superalkali cluster Li3F2 was conducted using high-level ab initio techniques. Equilibrium structures for both the neutral and anionic states in the gas-phase were identified and their relative stabilities using atomization enthalpies are analysed and compared with their respective proton affinities and gas-phase basicities. Our calculations, using a modified form of the CBS-QB3 composite method, identified several unique structures that possess superbase potential comparable to the proton affinity of Roger Alder's canonical Proton Sponge. The calculations show that, in general, as the number of hydroxide groups increase, so too does the proton affinity. PMID- 29192915 TI - Observation of A Raman mode splitting in few layer black phosphorus encapsulated with hexagonal boron nitride. AB - We investigate the impact of encapsulation with hexagonal boron nitride (h-BN) on the Raman spectrum of few layer black phosphorus. The encapsulation results in a significant reduction of the line width of the Raman modes of black phosphorus, due to a reduced phonon scattering rate. We observe a so far elusive peak in the Raman spectra ~4 cm-1 above the A mode in trilayer and thicker flakes, which had not been observed experimentally. The newly observed mode originates from the strong black phosphorus inter-layer interaction, which induces a hardening of the surface atom vibration with respect to the corresponding modes of the inner layers. The observation of this mode suggests a significant impact of h-BN encapsulation on the properties of black phosphorus and can serve as an indicator of the quality of its surface. PMID- 29192916 TI - Theoretical investigation of the impact of ligands on the regiodivergent Rh catalyzed hydrothiolation of allyl amines. AB - The reaction mechanisms of the Rh-catalyzed regiodivergent hydrothiolation of allyl amines have been theoretically investigated with the aid of density functional theory (DFT) calculations. The impact of ligands on the regioselectivity was rationalized. The origin of the regioselectivity involved in these reactions was probed by investigating the electronic and steric effects. The regioselectivity is derived from the stability of related intermediates. Among them, the steric effect plays an important role in controlling the regioselectivity. The origin of the regioselectivity could also be interpreted through the electronic effect on the corresponding transition states. PMID- 29192917 TI - Unexpected catalytic performance of Fe-M-C (M = N, P, and S) electrocatalysts towards oxygen reduction reaction: surface heteroatoms boost the activity of Fe2M/graphene nanocomposites. AB - The rational design of non-noble materials as low-cost, highly efficient, and durable catalysts to improve the oxygen reduction reaction is extremely urgent and challenging. The oxygen reduction reaction is a kinetically sluggish process that greatly affects the energy conversion efficiency. In this paper, novel hierarchical heteroatoms-co-doped Fe2M/graphene (M = P, N) nanocomposites were developed by a facile strategy, including hydrothermal and subsequent calcination methods. The thermal treatment of an ionic liquid and thiourea not only supplied heteroatom sources but also promoted the formation of iron phosphide and iron nitride and enhanced their catalytic performances. The electrochemical results indicated that the as-obtained hybrid catalysts manifested enhanced electrocatalytic activity toward the oxygen reduction reaction owing to the strong synergistic effects. The high content of heteroatoms distributed on the surface and interface of the hybrids and the density functional theory calculations suggested that Fe-N-C, Fe-P-C, and Fe-S-C multiple active surface sites were formed at the hybrids interfaces. Moreover, these results demonstrated that heteroatom-doped catalysts could effectively form a charge-transfer channel and thus modify the charge distribution in the hybrids interfaces. The as prepared heteroatoms-doped Fe2M/graphene hybrids would be developed into highly efficient catalysts as ideal alternatives for noble metal catalysts in practical applications. PMID- 29192918 TI - External oxidant-free cross-coupling: electrochemically induced aromatic C-H phosphonation of azoles with dialkyl-H-phosphonates under silver catalysis. AB - A convenient external oxidant-free method of phosphorylation of azole derivatives (benzo-1,3-azoles, 3-methylindole, 4-methyl-2-acetylthiazole) by using dialkyl-H phosphonates through the catalytic oxidation of their mixture under electrochemical mild conditions (room temperature, normal pressure) in the presence of silver salts or oxide (1%) is proposed. This method allows us to obtain the desired azole dialkylphosphonates with good yield (up to 75%). The transformations of silver and phosphorus precursors and intermediates using cyclic voltammetry, ESR, and NMR spectroscopy were investigated, and a radical process mechanism was proposed. It has been found that AgP(O)(OEt)2 is oxidized earlier than other components of the reaction mixture with the elimination of a radical. The ESR spectrum of this radical's adduct was obtained in the presence of the radical trap PBN. Ag2+ is out of the catalytic cycle. PMID- 29192919 TI - Oxidative stress-induced increase of intracellular zinc in astrocytes decreases their functional expression of P2X7 receptors and engulfing activity. AB - Neuron-glia communication mediated by neuro- and glio-transmitters such as ATP and zinc is crucial for the maintenance of brain homeostasis, and its dysregulation is found under pathological conditions. It is reported that under oxidative stress-loaded conditions, astrocytes exhibit increased intra- and extra cellular labile zinc, the latter triggering microglial M1 activation, while the pathophysiological role of the former remains unrevealed. In this study, we examined whether the oxidative stress-induced increase of intracellular labile zinc is involved in the P2X7 receptor (P2X7R)-mediated regulation of astrocytic engulfing activity. The exposure of cultured astrocytes to sub-lethal oxidative stress through their treatment with 400 MUM H2O2 increased intracellular labile zinc, of which the concentration reached a peak level of approximately 2 MUM at 2 h after the treatment. In astrocytes under sub-lethal oxidative stress, the uptake of YO-PRO-1 and latex beads as markers for P2X7R channel/pore activity and astrocytic engulfing activity, respectively, was decreased, and these decreased activities were accompanied by decreased expression of P2X7R at the plasma membrane via intracellular labile zinc-mediated translocation of it. With the oxidative stress, the expression level of full length P2X7R relative to that of its splice variants in astrocytes was decreased, leading to a decrease of the relative expression of the trimer consisting of full length P2X7R. Collectively, sub-lethal oxidative stress induces an astrocytic modal shift from the normal resting engulfing mode to the activated astrogliosis mode via an intracellular labile zinc-mediated decrease of the functional expression of P2X7R.

PMID- 29192921 TI - Escape of anions from geminate recombination in THF due to charge delocalization. AB - Geminate recombination of 24 radical anions (M-) with solvated protons (RH2+) was studied in tetrahydrofuran (THF) with pulse radiolysis. The recombination has two steps: (1) diffusion of M- and RH2+ together to form intimate (contact and solvent separated) ion pairs, driven by Coulomb attraction; (2) annihilation of anions due to proton transfer (PT) from RH2+ to M-. The non-exponential time dependence of the geminate diffusion was determined. For all molecules protonated on O or N atoms the subsequent PT step is too fast (<0.2 ns) to measure, except for the anion of TCNE which did not undergo proton transfer. PT to C atoms was as slow as 70 ns and was always slow enough to be observable. A possible effect of charge delocalization on the PT rates could not be clearly separated from other factors. For 21 of the 24 molecules studied here, a free ion yield (71.6 +/- 6.2 nmol J-1) comprising ~29% of the total, was formed. This yield of "Type I" free ions is independent of the PT rate because it arises entirely by escape from the initial distribution of ion pair distances without forming intimate ion pairs. Three anions of oligo(9,9-dihexyl)fluorenes, Fn- (n = 2-4) were able to escape from intimate ion-pairs to form additional yields of "Type II" free ions with escape rate constants near 3 * 106 s-1. These experiments find no evidence for an inverted region for proton transfer. PMID- 29192922 TI - Novel penta-graphene nanotubes: strain-induced structural and semiconductor-metal transitions. AB - Research into novel one-dimensional (1D) materials and associated structural transitions is of significant scientific interest. It is widely accepted that a 1D system with a short-range interaction cannot have 1D phase transition at finite temperature. Herein, we propose a series of new stable carbon nanotubes by rolling up penta-graphene sheets, which exhibit fascinating well-defined 1D phase transitions triggered by axial strain. Our first-principles calculations show that such penta-graphene nanotubes (PGNTs) are dynamically stable by phonon calculations, but transform from a tri-layer structure to a highly defective single-walled nanotube at low temperature in molecular dynamics simulations. We show that moderate compressive strains can drive structural transitions of (4,4), (5,5), and (6,6) PGNTs, during which the distances of neighboring carbon dimers in the inner shell have a sudden drop, corresponding to dimer-dimer nonbonding to bonding transitions. After such transition, the tubes become much more thermally stable and undergo semiconductor-metal transitions under increasing strain. The band gaps of PGNTs are not sensitive to chirality whereas they can be tuned effectively from visible to short-wavelength infrared by appropriate strain, making them appealing materials for flexible nano-optoelectronics. These findings provide useful insight into unusual phase transitions in low-dimensional systems. PMID- 29192923 TI - Electron beam induced tunneling magnetoresistance in spatially confined manganite bridges. AB - Certain manganites exhibit rich and technologically relevant transport properties which can often be attributed to the existence and changes of the intrinsic electronic phase competition within these materials. Here we demonstrate that a scanning electron beam can be used to artificially create domain configurations within La0.3Pr0.4Ca0.3MnO3 thin film microbridges that results in novel magneto transport effects. In particular, the electron beam preferentially produces insulating regions within the narrow film and can be used to create a configuration consisting of ferromagnetic metallic domains separated by a potential barrier. This arrangement enables the spin-dependent tunneling of charge carriers and can produce large switching tunneling magnetoresistance effects which were initially absent. Hence, this work describes a new and potentially powerful method for engineering the electronic phase domains in manganites to generate functional transport properties that are important for spintronic devices. PMID- 29192924 TI - NiMn2O4 spinel binary nanostructure decorated on three-dimensional reduced graphene oxide hydrogel for bifunctional materials in non-enzymatic glucose sensor. AB - Nickel-manganese spinel oxide (NiMn2O4) was hybridized with reduced graphene oxide hydrogel (rGOH) via a facile solvothermal process and a highly porous three dimensional (3D) structure was constructed. NiMn2O4/rGOH exhibited excellent electrochemical performance due to the high specific surface area, excellent electrocatalytic activity, and enhanced electrical conductivity due to the synergetic effects between the two components. The NiMn2O4/rGOH exhibited excellent glucose sensing performance with high sensitivity (1310.8 MUA mM-1 cm 2), a wide linear range (2 MUM-20 mM), rapid response time (<3.5 s), and anti interference properties. Furthermore, it also showed excellent supercapacitor performance with a high capacitance (396.85 F g-1) and excellent energy and power density on account of the large surface area and pseudo-capacitor behavior of NiMn2O4. A self-powered glucose sensor can be fabricated with NiMn2O4/rGOH as both supercapacitor and glucose sensing electrodes. PMID- 29192925 TI - Work function and temperature dependence of electron tunneling through an N-type perylene diimide molecular junction with isocyanide surface linkers. AB - Conducting probe atomic force microscopy (CP-AFM) was employed to examine electron tunneling in self-assembled monolayer (SAM) junctions. A 2.3 nm long perylene tetracarboxylic acid diimide (PDI) acceptor molecule equipped with isocyanide linker groups was synthesized, adsorbed onto Ag, Au and Pt substrates, and the current-voltage (I-V) properties were measured by CP-AFM. The dependence of the low-bias resistance (R) on contact work function indicates that transport is LUMO-assisted ('n-type behavior'). A single-level tunneling model combined with transition voltage spectroscopy (TVS) was employed to analyze the experimental I-V curves and to extract the effective LUMO position epsilonl = ELUMO - EF and the effective electronic coupling (Gamma) between the PDI redox core and the contacts. This analysis revealed a strong Fermi level (EF) pinning effect in all the junctions, likely due to interface dipoles that significantly increased with increasing contact work function, as revealed by scanning Kelvin probe microscopy (SKPM). Furthermore, the temperature (T) dependence of R was found to be substantial. For Pt/Pt junctions, R varied more than two orders of magnitude in the range 248 K < T < 338 K. Importantly, the R(T) data are consistent with a single step electron tunneling mechanism and allow independent determination of epsilonl, giving values compatible with estimates of epsilonl based on analysis of the full I-V data. Theoretical analysis revealed a general criterion to unambiguously rule out a two-step transport mechanism: namely, if measured resistance data exhibit a pronounced Arrhenius-type temperature dependence, a two-step electron transfer scenario should be excluded in cases where the activation energy depends on contact metallurgy. Overall, our results indicate (1) the generality of the Fermi level pinning phenomenon in molecular junctions, (2) the utility of employing the single level tunneling model for determining essential electronic structure parameters (epsilonl and Gamma), and (3) the importance of changing the nature of the contacts to verify transport mechanisms.

A challenge encountered in the context of such approaches in conductive media, including aqueous buffers, is the generation of electrolysis products at the electrode/liquid interface which can lead to contamination, perturb fluid flows and generally interfere with the measurement process. Here, we address this challenge by designing a single layer microfluidic device architecture where the electric potential is applied outside and downstream of the microfluidic device while the field is propagated back to the chip via the use of a co-flowing highly conductive electrolyte solution that forms a stable interface at the separation region of the device. The co-flowing electrolyte ensures that all the generated electrolysis products, including Joule heat and gaseous products, are flowed away from the chip without coming into contact with the analytes while the single layer fabrication process where all the structures are defined lithographically allows producing the devices in a simple yet highly reproducible manner. We demonstrate that by allowing stable and effective application of electric fields in excess of 100 V cm-1, the described platform provides the basis for rapid separation of heterogeneous mixtures of proteins and protein complexes directly in their native buffers as well as for the simultaneous quantification of their charge states. We illustrate this by probing the interactions in a mixture of an amyloid forming protein, amyloid-beta, and a molecular chaperone, Brichos, known to inhibit the process of amyloid formation. The availability of a platform for applying stable electric fields and its compatibility with single-layer soft lithography processes opens up the possibility of separating and analysing a wide range of molecules on chip, including those with similar electrophoretic mobilities.

AB - Three series of six pyrazine-2-amidoxime (H2pzaox)-based 3d-4f clusters, {Ln8Ni6}, {Ln5Ni10} and {Ln5Ni8} (Ln = Dy and Gd), were solvothermally synthesized in the absence or presence of different coligands, and were structurally and magnetically characterized. The unusual ring-shaped {Ln8(MU3 OH)4} core in the two {Ln8Ni6} complexes is generated by four corner-sharing triangle {Ln3(MU3-OH)} units, which are further connected to six outer NiII ions by twelve deprotonated H2pzaox ligands in three common binding modes. By contrast, the remaining four clusters contain only two corner-sharing {Ln3(MU3 OH)} triangles, which interact with peripheral NiII ions through fourteen H2pzaox ligands in five (for {Ln5Ni10}) and four (for {Ln5Ni8}) different bridging ways. Thus, the interesting core motifs observed in these clusters depend significantly on the number of the triangular {Ln3(MU3-OH)} subunits and their connectivity manner with the singly and doubly deprotonated pyrazine-2-amidoxime ligand. Additionally, weak ferromagnetic superexchange in the {Dy5Ni10} and {Ln5Ni8} clusters and antiferromagnetic coupling in {Ln8Ni6} and {Gd5Ni10} clusters was respectively mediated by versatile oximate bridges between the intramolecular LnIII and NiII ions. Furthermore, the three DyIII-derived aggregates exhibit slightly temperature-dependent magnetic relaxations under a zero dc field, and the three GdIII-based clusters display large magnetic entropy changes of 23.5 J kg-1 K-1 for {Gd8Ni6}, 19.4 J kg-1 K-1 for {Gd5Ni10}, and 22.4 J kg-1 K-1 for {Ln5Ni8} at 4.0 K and 70 kOe. These interesting results are helpful for the understanding of oximate-based 3d-4f coordination chemistry and their structure function relationships.

AB - A method to synthesize 2-methylbenzoxazoles directly from N-phenylacetamides catalyzed by Pd(OAc)2 in the presence of K2S2O8 and TfOH has been developed. The desired products were obtained in moderate to excellent yields. This approach provides a facile procedure to prepare benzoxazoles with available substrates. It is found that TfOH is the key factor for this cyclization reaction. A plausible mechanism of the reaction is proposed according to the control reactions and the literature.

AB - We investigate creeping viscoelastic fluid flow through two-dimensional porous media consisting of random arrangements of monodisperse and bidisperse cylinders, using our finite volume-immersed boundary method introduced in S. De, et al., J. Non-Newtonian Fluid Mech., 2016, 232, 67-76. The viscoelastic fluid is modeled with a FENE-P model. The simulations show an increased flow resistance with increase in flow rate, even though the bulk response of the fluid to shear flow is shear thinning. We show that if the square root of the permeability is chosen as the characteristic length scale in the determination of the dimensionless Deborah number (De), then all flow resistance curves collapse to a single master curve, irrespective of the pore geometry. Our study reveals how viscoelastic stresses and flow topologies (rotation, shear and extension) are distributed through the porous media, and how they evolve with increasing De. We correlate the local viscoelastic first normal stress differences with the local flow topology and show that the largest normal stress differences are located in shear flow dominated regions and not in extensional flow dominated regions at higher viscoelasticity. The study shows that normal stress differences in shear flow regions may play a crucial role in the increase of flow resistance for viscoelastic flow through such porous media. PMID- 29192930 TI - Simple peptide coacervates adapted for rapid pressure-sensitive wet adhesion. AB - We report here that a dense liquid formed by spontaneous condensation, also known as simple coacervation, of a single mussel foot protein-3S-mimicking peptide exhibits properties critical for underwater adhesion. A structurally homogeneous coacervate is deposited on underwater surfaces as micrometer-thick layers, and, after compression, displays orders of magnitude higher underwater adhesion at 2 N m-1 than that reported from thin films of the most adhesive mussel-foot-derived peptides or their synthetic mimics. The increase in adhesion efficiency does not require nor rely on post-deposition curing or chemical processing, but rather represents an intrinsic physical property of the single-component coacervate. Its wet adhesive and rheological properties correlate with significant dehydration, tight peptide packing and restriction in peptide mobility. We suggest that such dense coacervate liquids represent an essential adaptation for the initial priming stages of mussel adhesive deposition, and provide a hitherto untapped design principle for synthetic underwater adhesives.

AB - A series of new pincer-type tridentate o-aryloxide-N-heterocyclic carbene nickel complexes Ni1-Ni3 were synthesized, and the molecular structure of Ni3 was confirmed by X-ray crystallography. In comparison with the above tridentate complexes, the bidentate bis(aryloxide-NHC) nickel complex Ni4 was also synthesized. On activation with either Et2AlCl or Me2AlCl, all nickel complexes showed low activity toward norbornene (NB) homopolymerization. Surprisingly, Ni1 Ni3 catalysts exhibited moderate to high activity toward the homopolymerization (up to 3.21 * 106 g PNB (mol of Ni)-1 h-1) and copolymerization of norbornene with 1-octene (up to 1.39 * 105 g polymer (mol of Ni)-1 h-1) with B(C6F5)3 as the cocatalyst even at 100 degrees C, showing that tridentate nickel catalysts have high thermal stability. Notably, the tridentate Ni1-Ni3 complexes showed better activities than the corresponding bidentate bis(aryloxide-NHC) nickel complex Ni4. The obtained poly(NB-co-1-octene)s were confirmed to be vinyl-addition copolymers, which exhibited high 1-octene insertion ratio (9%-17%), good thermal stability (Td > 400 degrees C), high molecular weight (up to 105), and narrow molecular weight distribution (PDI <= 1.91).

AB - Treatment of proximal hamstring avulsions is challenging regarding both timing and choice of repair. In chronic situations, the tissue can become attenuated, bringing into question the need for adjunctive allograft. In general, proximal hamstring avulsions are affixed back to the ischial tuberosity with suture anchors, with allograft used as needed for chronic situations. This article reports on a novel technique of suspensory fixation with a unicortical button but without allograft to repair both acute and chronic proximal hamstring avulsions.

PMID- 29192933 TI - Short-term Outcomes of Total Knee Arthroplasty Performed at an Orthopedic Specialty Hospital. AB - This study compared perioperative outcomes for total knee arthroplasty (TKA) at an orthopedic specialty hospital and a tertiary referral center. The authors identified all primary TKA procedures performed in 2014 at the 2 facilities. Each patient at the orthopedic specialty hospital was manually matched to a patient at the tertiary referral center according to demographic and clinical variables. Matching was blinded to outcomes. Outcomes were 90-day readmission, mortality rate, reoperation, length of stay, and use of inpatient rehabilitation. Each group had 215 TKA patients. The 2 groups of patients were similar in age (66.8 years, P=.98), body mass index (30.4 kg/m2, P=.99), age-adjusted Charlson Comorbidity Index (3.4, P=1.00), and sex (46.0% male, P=1.00). Mean length of stay was 1.47+/-0.62 days at the orthopedic specialty hospital vs 1.87+/-0.75 days (P<.01) at the tertiary referral center. There were 3 readmissions at the orthopedic specialty hospital and 6 readmissions at the tertiary referral center (P=.31). There were 6 reoperations at the orthopedic specialty hospital and 5 at the tertiary referral center (P=.76). In addition, 8 patients at the orthopedic specialty hospital used inpatient rehabilitation vs 15 patients at the tertiary referral center (P=.08). One patient who was treated at the orthopedic specialty hospital required transfer to a tertiary referral center. This study found that perioperative outcomes were similar for matched patients who underwent primary TKA at an orthopedic specialty hospital and a tertiary referral center. Patients treated at the orthopedic specialty hospital spent 0.4 fewer days in the hospital compared with matched patients who were treated at the tertiary referral center. This equals 2 fewer hospital nights for every 5 TKA patients. [Orthopedics. 2018; 41(1):e84-e91.].

AB - Baseball pitching imposes significant stress on the upper extremity and can lead to injury. Many studies have attempted to predict injury through pitching mechanics, most of which have used laboratory setups that are often not practical for population-based analysis. This study sought to predict injury risk in professional baseball pitchers using a statistical model based on video analysis evaluating delivery mechanics in a large population. Career data were collected and video analysis was performed on a random sample of former and current professional pitchers. Delivery mechanics were analyzed using 6 categories: mass and momentum, arm swing, posture, position at foot strike, path of arm acceleration, and finish. Effects of demographics and delivery scores on injury were determined using a survival analysis, and model validity was assessed. A total of 449 professional pitchers were analyzed. Risk of injury significantly increased with later birth date, role as reliever vs starter, and previous major injury. Risk of injury significantly decreased with increase in overall delivery score (7.8%) and independently with increase in score of the mass and momentum (16.5%), arm swing (12.0%), and position at foot strike (22.8%) categories. The accuracy of the model in predicting injury was significantly better when including total delivery score compared with demographic factors alone. This study presents a model that evaluates delivery mechanics and predicts injury risk of professional pitchers based on video analysis and demographic variables. This model can be used to assess injury risk of professional pitchers and can be potentially expanded to assess injury risk in pitchers at other levels. [Orthopedics. 2018; 41(1):43-53.].

AB - Patients who undergo open reduction and internal fixation of distal clavicle fractures have a high rate of hardware removal and persistence of symptoms, particularly when attempting to return to high-demand activities. This study evaluated the outcomes of military servicemembers after surgical treatment of distal clavicle fractures. The authors performed a retrospective analysis of active duty servicemembers who underwent open reduction and internal fixation of Neer type II distal clavicle fractures between October 17, 2007, and July 20, 2012, with a minimum of 2-year clinical follow-up. The electronic health record was queried to extract demographic features and clinical outcomes, primarily persistence of pain, removal of hardware, and postoperative return to high-level activity. A total of 48 patients were identified, with mean follow-up of 3.8 years. A total of 44% of patients underwent subsequent hardware removal. All fractures achieved radiographic union, and 35% of patients had persistence of symptoms. Patients who were treated with hook plating had a 3.64-fold higher risk of persistence of pain compared with those treated with conventional plating techniques. A total of 35% of patients successfully returned to full military function and completed a postoperative military deployment. Coracoclavicular reconstruction did not improve outcomes. Persistence of symptoms and requirement for hardware removal were not associated with the rate of postoperative deployment. Achieving excellent functional outcomes with open reduction and internal fixation of distal clavicle fractures remains a challenge. Where possible, conventional plate fixation should be considered over hook plate fixation. However, subsequent hardware removal and continuing shoulder pain do not preclude a return to high-level activity. [Orthopedics. 2018; 41(1):e117 e126.].

AB - This study compared patients who underwent femoral head microfracture with a control group of patients who did not require microfracture. Patients had more than 2 years of follow-up. The patient groups had similar demographic and radiographic features, including sex, age within 5 years, body mass index within 5 points, equal Tonnis grade, lateral center edge angle within 5 degrees , labral treatment, and capsular closure vs release. Inclusion criteria were a minimum of 2 years of follow-up, Outerbridge grade IV cartilage damage, and femoral head marrow stimulation technique performed at the time of arthroscopy. Exclusion criteria were revision surgery, dysplasia, Tonnis grade of greater than 1, protrusio or profunda acetabuli, Perthes disease of the hip, slipped capital femoral epiphysis, abductor tear, and avascular necrosis of the hip. Patient reported outcomes included modified Harris hip score, nonarthritic hip score, hip outcome score-activity of daily living subscale, hip outcome score-sports subscale, and visual analog scale score for pain. Fifteen patients had femoral head microfracture with more than 2 years of follow-up. Mean improvements in modified Harris hip score, nonarthritic hip score, hip outcome score-sports subscale, and visual analog scale score were 17.1, 19.4, 30.5, and 2.8, respectively, for the microfracture group compared with 11.8, 18.5, 22.2, and 3.0, respectively, for the control group. Both groups showed statistically significant improvement (P<.05) for all patient-reported outcomes, and no significant difference was found between the 2 patient groups at latest follow up. Two patients in the microfracture group vs 3 patients in the control required hip arthroplasty. Femoral head microfracture is a technically difficult procedure, but when performed correctly, the results are similar to those of patients who do not require microfracture. Further study of femoral head microfracture is necessary to confirm these encouraging short-term outcomes. [Orthopedics. 2018; 41(1):e70-e76.]. PMID- 29192937 TI - Primary Total Hip Arthroplasty With Same-Day Discharge: Who Failed and Why. AB - As the emphasis on value-based care within total joint arthroplasty increases, this procedure is becoming more prevalent in the outpatient setting. The goals of this study were to report on the authors' early experiences with same-day discharge and to identify patient characteristics that are associated with failure to discharge after total hip arthroplasty within this program. All patients who were enrolled in the same-day discharge total hip arthroplasty program at the study institution between January 2015 and July 2016 were included. Demographics, baseline characteristics, and clinical and quality outcomes were compared between patients who successfully completed this program and those who did not. Of the 163 study subjects, 143 (87.7%) were discharged successfully on the same day as surgery. Women, patients younger than 40 years, and patients older than 60 years all had an increased risk of failing the program. Body mass index of 26 kg/m2 or less was associated with a 40% greater risk of failure. Patients with an American Society of Anesthesiologists score of 3 had a 3-fold risk of failure compared with patients with an American Society of Anesthesiologists score of 2 or less. The screening protocol for same-day discharge at the study institution had an 87.7% rate of successful same-day discharge.

AB - OBJECTIVE: In recent years, the recovery-oriented approaches (along with experiences and thoughts of patients and patient's relatives) have been taken into account for establishing mental health services and policies. This study aims to identify the factors contributing to recovery, as observed from the perspective of schizophrenia patients working at The Blue Horse Cafe which was founded by the Federation of Schizophrenia Associations. METHOD: The sample for the study consisted of 24 patients who worked at The Blue Horse Cafe. A phenomenological approach was used in the study, whereby interviews with patients were analyzed qualitatively. RESULTS: Certain common factors, which were expressed as having contributed to recovery, were identified from the perspective of schizophrenia patients. These factors are: 1-The fact that the setting is informal and welcoming without being constrictive; 2-Predominance of the human element; 3-Hope and encouragement; 4-Being cared about; 5-Being able to reach someone when in need of support; 6-Friendly sharing; 7-Having a purpose, assuming responsibility, and being motivated; and 8-Giving meaning to life. CONCLUSION: The findings may serve as a stimulus since schizophrenia patients that contribute to recovery give mental health professionals the opportunity to question there need for a change in their professional roles. Additionally, schizophrenia patients that have experienced The Blue Horse Cafe draw attention to certain points and these points can serve as a guide, especially for establishing the working METHODS of Community Mental Health Centers.

AB - OBJECTIVE: Impairment in immune functions is proposed as a key factor in the cognitive decline in bipolar disorder (BD) however there is scarcity of research on the impact of inflammation on cognitive functions. Our aim is to compare IL-18 and IL-6 levels in BD patients and controls and to study the relationship between IL-18 and IL-6 levels and cognitive impairment METHOD: Thirty-six euthymic BD-I patients and 38 age, sex and educational level matched healthy controls were enrolled in the study. All participants were evaluated with neurocognitive tests. The plasma IL-6 and IL-18 levels of both groups were measured with ELISA kits. RESULTS: There was no statistically significant difference between IL-6 and IL-18 levels of patient and healthy control groups. In the patient group, IL-18 level was positively correlated with completed categories score wheras there was a negative correlation with perseverative response and perseverative errors. Moreover IL-18 level was positively correlated with immediate recall, delayed recall and learning scores while there was a negative correlation with stroop interference scores. No correlation was found between IL-6 level and neuropsychological test scores in the patient group. CONCLUSION: This is the first study that investigates the relation of IL-18 with cognitive functions. Possible detrimental or protective effects of IL-18 in BD is not yet clear, however the positive association of IL-18 level and neuropsychological test scores might indicate a neuroprotective role of IL-18 in the euthymic period of BD which is the closest state to physiological condition.

But this approach generally results with poor outcomes, and increased adverse effects. It is aimed to investigate the comparison of cases who diagnosed with PDDs and Mild Mental Retardation (MR) and cases with pure ADHD in terms of the clinical response to MPH. Also we aimed to investigate the relations between CES-1 polymorphism gene and the clinical response to MPH. METHODS: For clarifying this we searched for three polymorphisms (Arg199/His, Ser75/Asn, and Ile49/Val) in carboxylesterase-1 gene (CES-1) in the saliva of patients diagnosed with PDD+ADHD. Also, we assessed the clinical response to MPH by dimensional approach using the Attention Deficit Hyperactivity Disorder Rating Scale IV and Clinical Global Impression-Improvement scale. RESULTS: PDD+ADHD groups had significantly higher Arg199/His polymorphism, and clinically responded poorer with symptoms sometimes even worsening to the MPH treatment compared with "pure" ADHD and ADHD+MR groups. CONCLUSION: This is the first study that an association between Arg199/His polymorphism in CES1 and altered treatment response to MPH in patients with PDD that presents with symptoms of ADHD.

AB - OBJECTIVE: The aim of this study was to examine the correlation between shyness, perception of general self-efficacy, and life satisfaction in young adolescents. METHOD: The study participants included 489 freshman students living in Turkey and studying under different faculty at public universities in Ankara (184 female; 37.6% and 305 male; 62.4%). The subjects ranged in age between 18 (n = 207; 42.3%) and 19 (n = 282; 57.7%) years. Study data collection included the Shyness Scale (Cheek and Buss 1981), the Perception of General Self-efficacy Scale (Schwarzer and Jerusalem 1995), and the General Life Satisfaction Scale (Diener, Emmons, Laresen and Griffin 1985). The data obtained were examined through Correlation analysis, simple linear regression analysis, multiple linear regression analysis and the sobel test. RESULTS: The results of the study showed that there was a moderately significant negative correlation between shyness and perception of general self-efficacy, moderately significant negative correlation between shyness and life satisfaction and moderately significant positive correlation between the perception of general self-efficacy and life satisfaction. Finally, the level of shyness and perceptions of general self efficacy significantly predicted life satisfaction. CONCLUSION: The findings of the present study may contribute to a better understanding of the relationship between shyness, perception of self-efficacy and "life satisfaction. The results are discussed in the context of the current literature on these topics.

AB - OBJECTIVE: This study aimed to examine the cognitive profiles of children with Attention Deficit and Hyperactivity Disorder (ADHD) with the Wechsler Intelligence Scales for Children-Revised (WISC-R) and the Wechsler Intelligence Scales for Children-Fourth Edition (WISC-IV), the latter of which was recently standardized in Turkey. In addition, the reading abilities and intelligence scores of these children were also investigated. METHODS: A total of 48 children with ADHD between the ages of 6 and 16 years who were outpatients in Mus State Hospital were included in this study. The children were administered the WISC-R, the WISC-IV, and the Oral Reading Skills and Reading Comprehension Test (ORCT). RESULTS: There were no significant differences between the WISC-R IQ scores and WISC-IV index scores. Moreover, reading comprehension skills (derived from ORCT scores) were predicted with significant accuracy by both the WISC-R Verbal IQ and the WISC-IV WMI (Working Memory Index). CONCLUSION: Results of this study suggest that the WISC-R and the WISC-IV scale are not sufficient for obtaining a specific cognitive profile for ADHD - there is no significant difference between them. However, the four-factor structure of the WISC-IV is believed to provide more specific information. In addition, results of this study related to reading skills indicate that the importance of reading skills should not be overlooked when assessing children with ADHD.

AB - Posttraumatic stress disorder (PTSD) is a condition that occurs after a traumatic event, and its diagnostic criteria include attention and memory deficits as well as symptoms of anxiety. We aimed to review the literature related to attention, memory, and executive functions in PTSD. Although studies on the subject are limited (in that there is no uniformity in terms of trauma type, selection of the control groups or types of neuropsychological tests used), most reported similar deficits in PTSD subjects in terms of memory and executive functions including attention. Since the presence of psychiatric comorbidities may disrupt neuropsychological functions, results of studies that have not controlled comorbidity may be questionable. However, studies that excluded the comorbid conditions reported similar deficits in cognitive functions in PTSD patients. The relationship between recovery from PTSD symptoms and change in cognitive functions has been examined in only a few studies, and most have reported an improvement for both memory and executive functions in remitted patients. The improvement in executive functions, however, has been limited by the difficulty of task. Cognitive deficits have been among the major causes of disabilities in PTSD patients. Therefore, the amount of improvement in cognitive dysfunctions by current treatments of PTSD deserves more attention.

AB - OBJECTIVE: In this study, it is aimed to evaluate the reliability and validity of the Turkish version of Hypomania Checklist-32-Revised. METHOD: The study was carried out with 80 patients diagnosed with bipolar I disorder, 26 patients diagnosed with bipolar II disorder and 42 patients diagnosed with major depressive disorder attending the out- and in-patient psychiatry departments of three university hospitals and one training hospital, and 116 healthy volunteers consisting of university students. Mean duration of illness was 15,1 years for the bipolar disorder group, and 9,3 years for the major depressive disorder group. For concurrent validity, Mood Disorder Questionnaire was used. In the statistical analysis, internal consistency coefficient, item-total score correlation coefficients, exploratory factor analysis, correlation with concurrent scale and ROC curve were calculated. RESULTS: Translation into Turkish and back-translation into English of Hypomania Checklist-32-Revised were performed and thus the semantic harmony of the scale was obtained. In the internal consistency, Cronbach alpha coefficient was 0,914 and item-total score correlations were between 0,235-0.743. Solely the coefficient of item #23 was found as 0,110. In factor analysis, six factors were obtained but a two-factor solution representing 44,5% of the total variance was accepted and first factor represents overactivity and being expansive, second factor represents impulsivity and risky behaviors. Correlation of Hypomania Checklist-32-R with Mood Disorder Questionnaire was r=0,379. In the ROC analysis, the cut off point of the scale was calculated as 14 with a sensitivity of 71,0 and specificity of 69,8. The scale discriminates well between the bipolar group, and depressive and control groups. CONCLUSION: Hypomania Checklist-32-Revised developed for screening hypomania is reported to be reliable and valid in Turkish after cutting out item #23.

Hyperhidrosis may be caused by drugs acting at the hypothalamus, spinal thermoregulatory centres, and sympathetic ganglia or at the eccrine-neuroeffector junction. Hyperhidrosis can be distressing and embarrassing symptom, which if not addressed properly, may lead to non concordance to medication. Two female patients are reported here who developed hyperhidrosis with aripiprazole. Both the patients stopped experiencing hyperhidrosis after their aripiprazole was discontinued. To the best of the knowledge of the author, no case of aripiprazole induced hyperhidrosis has been published in the literature.

FL damage can lead to executive dysfunction by influencing frontal-subcortical circuits (dorsolateral, orbitofrontal, ventromedial). Damage to the dorsolateral prefrontal cortex (DLPFC) can lead to deterioration in EF, whereas damage to the orbitofrontal cortex (OFC) can lead to personality changes with the characteristic of disinhibition and irritability. In addition, damage to the anterior cingulate cortex/medial prefrontal cortex (ACC/MPFC) can result in decreased spontaneity. Neuropsychological tests are important components in the assessment of EF including goal-directed behavior, decision-making, risk assessment, making plans for the future, setting of priorities and order of our actions. Clinical conditions affecting frontal-subcortical connections outside of the FL can also lead to executive dysfunctions and frontal lobe syndrome (FLS). This case report is about an adolescent patient diagnosed as FLS. The clinical symptoms, assessment and treatment processes of this case are discussed in this report. The case is a 15-year-old boy that was admitted to our clinic with behavioral problems, which began after a car accident three years ago. Magnetic resonance imaging (MRI) of the brain indicated hyperintense signal increase in periventricular deep white matter that is associated with traumatic brain damage. Neuropsychological tests results (Stroop, Wisconsin Card Sorting Test, Serial Digit Learning Test, Line Orientation Test, Verbal Memory Processes Scale) have demonstrated impairment in cognitive flexibility, verbal fluency, setting priority, inappropriate response inhibition, sustained attention, planning, problem solving, organization skills and subcortical memory functions. We thought that cognitive and behavioral symptoms of this case were associated with the dysfunctions of frontal-subcortical circuits, independent of an obvious frontal lesion. FLS for the patients with sudden-onset behavioral and cognitive problems after head traumas should be kept in mind in differential diagnosis, even in the absence of an obvious frontal lesion.

AB - BACKGROUND: The optimal approach to coronary bifurcation treatment by percutaneous coronary intervention (PCI) is still a subject of debate, and dedicated bifurcation stents are one of the proposed solutions. AIM: The aim of this report was to assess the effectiveness and safety profile of a new dedicated bifurcation stent - sirolimus-eluting BiOSS LIM C(r) (Balton, Poland) at the first three months of a 12-month registry. METHODS: This is a two-centre registry, which enrolled patients with non-ST elevation acute coronary syndrome (NSTE-ACS) and stable angina. Provisional T-stenting is the obligatory strategy of the treatment. Angiographic control is planned at 12 months. The primary endpoint is the cumulative rate of cardiac death, myocardial infarction (MI), and target lesion revas-cularisation (TLR) at 12 months. RESULTS: A total of 48 patients with lesions in coronary bifurcations were enrolled (mean age 67.9 +/- 8.9 years, 14.6% female). There were 20.8% of patients with NSTE-ACS, 93.8% with hypertension, 35.4% with diabetes, 52.1% had previous MI, and 47.9% and 14.6% underwent prior PCI and coronary artery bypass grafting, respectively. The device success rate was 100%. The side branch was treated with an additional classical drug-eluting stent implantation in 18.8% of cases. The periprocedural MI (MI type 4a) was observed in two (4.2%) cases. At three months there was one (2.1%) case of TLR. No death, MI, or stent thrombosis were observed in the follow-up period. CONCLUSIONS: Bifurcation treatment with a single dedicated bifurcation stent (BiOSS LIM C(r)) is feasible and highly successful (100% implantation success rate). The short-term clinical outcomes are very promising, also in distal left main stenosis. The 12-month observations are pending. PMID- 29192952 TI - Thromboelastography for predicting bleeding in patients with aortic stenosis treated with transcatheter aortic valve implantation. AB - BACKGROUND: Bleeding complications are frequent and independently impact mortality after transcatheter aortic valve implantation (TAVI). Thromboelastography (TEG) measures viscoelastic properties of clot formation and is currently best known for perioperative management to reduce blood transfusion in cardiac surgery. AIM: We sought to determine whether TEG may be predictive of bleeding in patients treated with TAVI. METHODS AND RESULTS: Overall, 54 consecutive patients with severe aortic stenosis treated with TAVI were prospectively included. In all patients, two blood samples were obtained for TEG measurement (the first - 12 h prior to procedure tested with citrated kaolin [CK] TEG assay, and the second - immediately after prosthesis deployment tested with CK and citrated heparinised kaolin assay [CHK]). Major or life-threatening bleeding (MLTB) was diagnosed in 13 (24%) patients. In receiver-operating characteristic (ROC) curve analysis the only TEG parameters showing significant sensitivity and specific-ity for predicting MLTB were those obtained in the CK sample at the end of the procedure: R value (reaction time, time to initiation of clot formation) area under the curve (AUC) 0.69, 95% confidence interval (CI) 0.49-0.88, p = 0.04; angle (the rate of clot formation), AUC 0.75, 95% CI 0.59 0.92, p = 0.007, and maximum amplitude (MA, ultimate strength of fibrin clot), AUC 0.77, 95% CI 0.62-0.93, p = 0.003. After controlling for confounding factors on multivariate logistic regression, MA remained as the only TEG parameter that significantly correlated with bleeding after TAVI, both as a continuous variable (p = 0.004; 95% CI 0.92-0.98; odds ratio [OR] 0.95 per 1 mm increment) and after using the cut-off value derived from ROC analysis; MA < 46.6 mm (OR 10.4; 95% CI 2.1-51.8; p = 0.004). CONCLUSIONS: Low strength of fibrin clot measured by TEG immediately after TAVI may serve as an independent predictor of short-term major and life-threatening bleeding complications. PMID- 29192953 TI - Relationship between serum homocysteine levels and structural-functional carotid arterial abnormalities in inactive Behcet's disease. AB - BACKGROUND: Behcet's disease (BD) is a chronic autoimmune disorder with symptoms manifesting from an underlying vasculitis. Since the disease activity is correlated with characteristic vascular endothelial dysfunction, BD places individuals at increased risk of cardiovascular diseases, such as atherosclerosis. Hyperhomocysteinaemia is an independent risk factor for arteriosclerotic vascular diseases. AIM: This study was designed to investigate how plasma homocysteine (Hcy) affects the structural and functional properties of the carotid artery in humans. METHODS: Sixty-eight BD patients with subclinical atherosclerosis and 40 healthy controls underwent carotid sonography and Doppler ultrasound to measure carotid artery intima-media thickness (C-IMT) and carotid stiffness and distensibility (indicat-ing elasticity). Total Hcy level was determined by enzyme-linked immunosorbent assay. For analysis, the BD patients were sub-grouped according to hyperhomocysteinaemia (> 15 MUmol/L). RESULTS: The patients with BD were found to have increased C-IMT and beta stiffness and decreased distensibility. In addition, hyperhomocysteinaemia was significantly correlated with these detrimental changes in the carotid artery, possibly raising the risk of these patients developing atherosclerosis. CONCLUSIONS: These findings suggest a potential mechanism of atherosclerosis in BD and highlight the processes that future research should focus on to address identification and prophylactic treatment of BD patients at risk of cardiovascular disease. PMID- 29192954 TI - Is heart rate recovery index a predictive factor for cardioinhibitory syncope? AB - BACKGROUND: Cardioinhibitory syncope is related with excessive bradycardia or asystole due to parasympathetic response. AIM: We investigated whether patients with cardioinhibitory syncope have higher heart rate recovery index (HRRi) considered as a parasympathetic system activation in exercise stress testing (EST) than in those with other neurogenic syncope forms. METHODS: A total of 262 patients who had neurogenic syncope documented by head-up tilt test (HUTT) and 199 healthy control individuals were examined. A maximal EST was applied to all patients after the HUTT. The HRRi was obtained by subtracting the heart rate that was measured at the first (HRRi-1), second (HRRi-2), and third minute (HRRi-3) of the recovery period from the maximal heart rate that was measured during the test. RESULTS: Eighty patients had cardioinhibitory syncope, 118 patients had vasodepressor syncope, and 64 patients had mixed-type syncope. The HRRi-1 was higher in patients with syncope (43.3 +/- 7.7) compared to the control group (34.5 +/- 4.8; p < 0.001). Post hoc analysis showed that among the syncope groups, there was no difference between patients with vasodepressor syncope (42.2 +/- 7.6) and those with mixed type syncope (40.7 +/- 4.1) in terms of HRRi-1 (p = 0.420). However, patients with cardioinhibitory syncope (47 +/- 8.7) had a higher HRRi-1 than vasodepressor and mixed-type syncope groups (p < 0.05). The threshold value of the HRRi-1, which can be used for the prediction of cardioinhibitory syncope development, was determined to be 41 with 75% sensitivity and 72% specificity. CONCLUSIONS: The HRRi-1 was higher in patients with cardioinhibitory syncope compared to the controls. The HRRi-1 has the predictive feature of differentiating cardioinhibitory syncope from other syncope types. PMID- 29192955 TI - Epidemiology of dyslipidaemia in professional drivers: results of RACER-ABPM (Risk of Adverse Cardiovascular Events among professional dRivers in Poland - Ambulatory Blood Pressure Monitoring) study. AB - BACKGROUND: Professional drivers are a group exposed to many cardiovascular risk factors. Non-systematic working hours, prolonged stress, low physical activity, along with irregular, and in most cases, unhealthy meals are common aspects of the normal working schedule of most of the professional drivers. These translate into high risk of cardiovascular disease (CVD). AIM: The aim of the current analysis was to establish the prevalence of dyslipidaemia in a group of continuous professional drivers. METHODS: The RACER (Risk of Adverse Cardiovascular Events among professional dRivers in Poland - Ambulatory Blood Pressure Monitoring) study is a prospective study focused on assessing cardiovascular risk factors in professional drivers. Patients included in the study were screened for classical and non-classical cardiovascular risk factors and had an ambulatory blood pressure monitoring (ABPM) performed. Out of the whole RACER study population, 144 drivers were included into the RACER-ABPM study. RESULTS: Out of this group 135 (95.7%) were male, and the mean age was 50.2 +/- 9.3 years, and mean body mass index was 32.3 +/- 3.0 kg/m2. A family history of CVD was noted in 21.3% of patients, 28.1% were current smokers, and 2.9% had diabetes mellitus. Out of those patients, 72.2% had low-density lipoprotein cholesterol (LDL-C) level > 115 mg/dL, 85.5% had LDL-C > 100 mg/dL, and 96.7% had LDL-C > 70 mg/dL. High-density lipoprotein cholesterol < 40 mg/dL in men and < 45 mg/dL in women was present in 84.4% of cases. Triglycerides > 150 mg/dL were found in 28.9% of cases. CONCLUSIONS: In conclusion, dyslipidaemia is highly prevalent in professional drivers. Obesity is one of the major contributors to the cardiovascular risk, and dyslipidaemia along with other risk factors highly prevalent in this subgroup accounts for poorer prognosis. PMID- 29192956 TI - Initial clinical experience with the first drug (sacubitril/valsartan) in a new class - angiotensin receptor neprilysin inhibitors in patients with heart failure with reduced left ventricular ejection fraction in Poland. AB - BACKGROUND: Sacubitril/valsartan is the first drug from a new class of angiotensin receptor neprilysin inhibitors (ARNIs) recommended in the new European Society of Cardiology guidelines instead of angiotensin converting enzyme inhibitors (ACEI), or angiotensin receptor blockers (ARB) that are used if ACEI are not tolerated. Sacubitril/valsartan is recommended for further reduction in the risk of hospitalisation or death in outpatients with heart failure with reduced ejection fraction (HFrEF) if symptoms continue despite optimal treatment with ACEI/ARB, beta-blockers, and mineralocorticoid antagonists. AIM: The aim of this study is to present the initial experience with regard to the effectiveness, tolerance, and safety of sacubitril/valsartan in the outpatient cardiology practice in Poland. METHODS: The study is a retrospective analysis of data obtained through a questionnaire filled in by the physicians who initiated the sacubitril/valsartan treatment in patients with HFrEF between 1 June 2016 and 30 September 2016. Patients were followed-up for three months. RESULTS: The analysis included data on 28 patients aged 61 +/- 16 years, of whom 85.7% were males. The drug was used in patients in New York Heart Association (NYHA) class I-III. In 25 (89.2%) patients sacubitril/valsartan was started at the lowest dose (24/26 mg BID). During follow-up the sacubitril/valsartan-treated patients had a reduction in HF symptoms assessed using the NYHA functional class (p = 0.001), a significant drop in N-terminal-pro B-type natriuretic peptide levels (mean, from 2900 to 2270 pg/mL; p = 0.008), and improved exercise tolerance, which occurred shortly after treatment initiation - after a mean of 28 days. CONCLUSIONS: It was demonstrated that the use of sacubitril/valsartan in outpatients with HFrEF is safe and is associated with a significant clinical improvement. PMID- 29192957 TI - The efficacy and safety of valsartan and a combination of valsartan and hydrochlorothiazide in the treatment of patients with mild to moderate arterial hypertension: a subgroup analysis of the effect of valsartan and its combination with.... AB - BACKGROUND AND AIM: The aim of the study was to establish the effect of valsartan and combination of valsartan and hydrochlorothiazide (HCTZ) on pulse wave velocity (PWV) and central blood pressure (CBP) in a large population of patients with mild to moderate arterial hypertension. METHODS: This was an international, multicentre, open-label, prospective trial. After one week of washout in previously treated patients, 74 subjects were treated with valsartan or valsartan combined with HCTZ for 16 weeks according to the protocol. Naive patients received the treatment immediately. During the active treatment, four visits were planned for each patient to obtain data for the primary and secondary efficacy. At the beginning and at the end of the study PWV and CBP were determined with central arterial pressure waveform analysis (SphygmoCor(r), Atcor Medical). This study is registered with clinicaltrialsregister.eu, EudraCT number 2012-005129 57. RESULTS: The results of the present VICTORY trial showed that valsartan and combination of valsartan and HCTZ effectively reduced the brachial blood pressure in patients with mild to moderate arterial hypertension as well as PWV, central systolic blood pressure and central diastolic blood pressure. The effects on the augmentation index were not statistically significant. CONCLUSIONS: Valsartan and valsartan/HCTZ improve arterial stiffness in patients with mild to moderate hypertension.

PMID- 29192960 TI - Nicotinamide and skin cancer chemoprevention: The jury is still out. AB - Following the publication of the results of a Phase III trial, the administration of oral nicotinamide has been widely advocated as effective in non-melanoma skin cancer chemoprevention in high-risk individuals. However, I performed a Bayesian analysis of the reported findings and show there is insufficient evidence to demonstrate its efficacy, highlighting the significant probability that the positive conclusions drawn will not be reproducible. Given the potential widespread use of oral nicotinamide, future position statements regarding its efficacy are likely to require higher standards of evidence. PMID- 29192961 TI - The incidence and outcome of clinically significant antibodies detected in Rhesus D positive pregnant women of the Northern Territory. AB - BACKGROUND: Haemolytic disease of the fetus/newborn secondary to clinically significant non-Rhesus-D antibodies has risen in importance since the advent of immunoprophylactic anti-D administration to Rhesus-D negative women. Of interest is the incidence of these antibodies in Rhesus-D positive women, who receive less frequent antenatal alloantibody screening. This is of particular concern if the antibodies arise late in pregnancy and may go undetected. AIMS: To assess the proportion of Rhesus-D positive pregnant women with late developing clinically significant antibodies for haemolytic disease of the fetus/newborn, and whether these resulted in adverse fetal outcomes. MATERIALS AND METHODS: A retrospective analysis over a 12-month period at a tertiary hospital in the Northern Territory. Group and antibody screen results in addition to clinical data regarding pregnancy/newborn were collected. RESULTS: Sixty-four of 2612 women (2.5%) had red blood cell antibodies detected during their pregnancy. Of these, 21 clinically significant antibodies were detected in 19 women (0.7% of initial cohort). The most common antibody detected was anti-c (28.5%). In six of these women (0.23% of initial cohort), the antibodies were late developing. Mild jaundice was noted in three newborns with phototherapy required in one. CONCLUSIONS: Although clinically significant antibodies were detected during pregnancy, and in a small proportion of cases as a late developing antibody undetected in the first trimester screening, clinical outcomes for the newborn were mild. As such, the cost of retesting all Rhesus-D positive pregnant women in the third trimester would be considerable and unlikely to result in any meaningful clinical benefit. PMID- 29192962 TI - External validity in perinatal research. AB - Recent studies are beginning to focus on the external validity of well conducted internally valid research. This review gives an overview of external validity, the dimensions involved and suggestions for when future intervention trials are designed, using examples from perinatal research. Finally, we remind the perinatal researcher that it is their duty to provide extensive details beyond those needed to establish internal validity. The latter would help clinicians to determine whether the intervention is applicable to their population. PMID- 29192963 TI - Reader reaction on the fast small-sample kernel independence test for microbiome community-level association analysis. AB - Zhan et al. () presented a kernel RV coefficient (KRV) test to evaluate the overall association between host gene expression and microbiome composition, and showed its competitive performance compared to existing methods. In this article, we clarify the close relation of KRV to the existing generalized RV (GRV) coefficient, and show that KRV and GRV have very similar performance. Although the KRV test could control the type I error rate well at 1% and 5% levels, we show that it could largely underestimate p-values at small significance levels leading to significantly inflated type I errors. As a partial remedy, we propose an alternative p-value calculation, which is efficient and more accurate than KRV p-value at small significance levels. We recommend that small KRV test p-values should always be accompanied and verified by the permutation p-value in practice. In addition, we analytically show that KRV can be written as a form of correlation coefficient, which can dramatically expedite its computation and make permutation p-value calculation more efficient.

PMID- 29192965 TI - Trends in readmission rate by route of hysterectomy - a single-center experience. AB - INTRODUCTION: The aim of this study was to assess the 60-day readmission rates after hysterectomy according to route of surgery and analyze risk factors for postoperative readmission. MATERIAL AND METHODS: This retrospective study included all women who underwent hysterectomy due to benign conditions from 2009 to 2015 at a large academic center in Boston. Readmission rates were compared among the following four types of hysterectomies: abdominal, laparoscopic, robotic and vaginal. RESULTS: There were 3981 hysterectomy cases over the study period (628 abdominal hysterectomy, 2500 laparoscopic hysterectomy, 155 robotic hysterectomy and 698 vaginal hysterectomy). Intraoperative complications occurred more frequently in women undergoing abdominal hysterectomy (4.8%), followed by robotic hysterectomy (3.9%), vaginal hysterectomy (1.9%) and laparoscopic hysterectomy (1.6%) (p < 0.0001). Readmission rates were not significantly different among the groups; women receiving abdominal hysterectomy had an overall readmission rate of 3.5%, compared with 3.2% after robotic hysterectomy, 2.9% after vaginal hysterectomy and 1.9% after laparoscopic hysterectomy (p = 0.06). When stratifying for relevant variables, women who had an laparoscopic hysterectomy had a twofold reduction of readmission compared with abdominal hysterectomy (odds ratio 0.52, 95% confidence interval 0.31-0.87; p = 0.01). There was no significant difference in readmission when robotic hysterectomy or vaginal hysterectomy were compared individually with abdominal hysterectomy. Regarding risk factors related to readmission it was observed that perioperative complications were the largest driver of readmissions (odds ratio 667, 95% confidence interval 158-99; p < 0.0001). CONCLUSION: The laparoscopic approach to hysterectomy was associated with fewer hospital readmissions compared with the abdominal route; vaginal, robotic and abdominal approaches had a similar risk of readmission. Perioperative complications represent the main driver of readmissions. After adjusting for perioperative factors such as surgeon type and complications, no difference in readmissions between the different routes of hysterectomy were found. PMID- 29192966 TI - Improving identification of idiopathic intracranial hypertension patients in Swedish patient register. AB - OBJECTIVE: Idiopathic intracranial hypertension (IIH) is often misdiagnosed. This can cause problems if conducting register-based studies. The study purpose was to produce algorithms that better identify patients with correct diagnosis of IIH in the Swedish National Patient Register (NPR). METHODS: Patients with ICD-10 code G93.2 for IIH registered in the NPR (2006-2013, Stockholm County) were included and diagnosis validated by medical record reviews. Patients were randomized into two groups: one used to produce the algorithm (n = 105) and one for validation (n = 102). We tested variables possible to extract from registries and used forward stepwise logistic regression which provided a predicted probability of correct diagnosis for each patient. RESULTS: We included 207 patients of which 135 had confirmed IIH. This gave a positive predictive value of 65.2% (CI: 58.4-71.4). The algorithm produced with variables extracted from registries, that is, age, number of times with diagnosis code G93.2 recorded (>2 times), and acetazolamide treatment, predicted the diagnosis correctly 88.2% (CI: 80.3-93.3) of the time. Excluding treatment data from the algorithm did not change the prediction notably, 86.3% (CI: 78.1-91.7). CONCLUSION: We produced two algorithms that with improved accuracy predict whether an IIH diagnosis in the NPR is correct. This can be a useful tool when performing register-based studies. PMID- 29192967 TI - Targeting Behavioral Symptoms and Functional Decline in Dementia: A Randomized Clinical Trial. AB - BACKGROUND/OBJECTIVES: Dementia-related behavioral symptoms and functional dependence result in poor quality of life for persons with dementia and their caregivers. The goal was to determine whether a home-based activity program (Tailored Activity Program; TAP-VA) would reduce behavioral symptoms and functional dependence of veterans with dementia and caregiver burden. DESIGN: Single-blind (interviewer), parallel, randomized, controlled trial (Clinicaltrials.gov: NCT01357564). SETTING: Veteran's homes. PARTICIPANTS: Veterans with dementia and their family caregivers (N = 160 dyads). INTERVENTION: Dyads in TAP-VA underwent 8 sessions with occupational therapists to customize activities to the interests and abilities of the veterans and educate their caregivers about dementia and use of customized activity. Caregivers assigned to attention control received up to 8 telephone-based dementia education sessions with a research team member. MEASUREMENTS: Primary outcomes included number of behaviors and frequency of their occurrence multiplied by severity of occurrence; secondary outcomes were functional dependence, pain, emotional well-being, caregiver burden (time spent caregiving, upset with behaviors) and affect at 4 (primary endpoint) and 8 months. RESULTS: Of 160 dyads (n = 76 TAP-VA; n = 84 control), 111 completed 4-month interviews (n = 51 TAP-VA; n = 60 control), and 103 completed 8-month interviews (n = 50 TAP-VA; n = 53 control). At 4 months, compared to controls, the TAP-VA group showed reductions in number (difference in mean change from baseline = -0.68, 95% CI = -1.23 to -0.13) and frequency by severity (-24.3, 95% CI = -45.6 to -3.1) of behavioral symptoms, number of activities needing assistance with (-0.80, 95% CI = -1.41 to -0.20), functional dependence level (4.09, 95% CI = 1.06, 7.13), and pain (-1.18, 95% CI = -2.10 to 0.26). Caregivers of veterans in TAP-VA reported less behavior-related distress. Benefits did not extend to 8 months. CONCLUSION: TAP-VA had positive immediate effects and no adverse events. Because TAP-VA reduces behavioral symptoms, slows functional dependence, and alleviates pain and caregiver distress, it is a viable treatment option for families. PMID- 29192968 TI - A regression framework for assessing covariate effects on the reproducibility of high-throughput experiments. AB - The outcome of high-throughput biological experiments is affected by many operational factors in the experimental and data-analytical procedures. Understanding how these factors affect the reproducibility of the outcome is critical for establishing workflows that produce replicable discoveries. In this article, we propose a regression framework, based on a novel cumulative link model, to assess the covariate effects of operational factors on the reproducibility of findings from high-throughput experiments. In contrast to existing graphical approaches, our method allows one to succinctly characterize the simultaneous and independent effects of covariates on reproducibility and to compare reproducibility while controlling for potential confounding variables. We also establish a connection between our model and certain Archimedean copula models. This connection not only offers our regression framework an interpretation in copula models, but also provides guidance on choosing the functional forms of the regression. Furthermore, it also opens a new way to interpret and utilize these copulas in the context of reproducibility. Using simulations, we show that our method produces calibrated type I error and is more powerful in detecting difference in reproducibility than existing measures of agreement. We illustrate the usefulness of our method using a ChIP-seq study and a microarray study. PMID- 29192969 TI - Effects of applying universal fetal growth standards in a Scandinavian multi ethnic population. AB - INTRODUCTION: The question of whether universal growth charts can be used in multi-ethnic settings is of general interest. The Intergrowth-21st fetal growth and newborn size standards are suggested to represent optimal fetal growth regardless of country origin. Our aim was to examine whether women fulfilling the strict Intergrowth-21st inclusion criteria were healthier, showed less ethnic differences in fetal growth and newborn size, and less adverse perinatal outcomes. MATERIAL AND METHODS: Data were drawn from a population-based multi ethnic cohort of 823 presumably healthy pregnant women in Oslo, Norway. We assessed differences in fetal and neonatal gestational age specific z-scores and compared maternal health parameters, pregnancy and birth complications between pregnancies fulfilling and not fulfilling the Intergrowth-21st criteria. RESULTS: Only 21% of pregnancies enrolled in our cohort fulfilled the Intergrowth-21st criteria. Fetal growth deviated substantially from the new standards, in particular for ethnic Europeans. Ethnic differences persisted in pregnancies fulfilling the criteria. In South Asian fetuses, estimated fetal weight was -0.60 SD (95% confidence interval -1.00, -0.20) lower at 24 gestational weeks, and birthweight was -0.62 SD (-0.95, -0.29) lower, compared with ethnic Europeans. Corresponding numbers for Middle-East/North Africans were -0.13 (-0.62, 0.36) and -0.60 (-1.00, -0.20). Maternal health indicators and birth complications were similar in women fulfilling and not fulfilling the criteria, but the relation depended on ethnic origin. CONCLUSIONS: In an urban multi-ethnic Norwegian population, applying an extensive list of criteria to define "healthy" pregnancies excludes the majority of women but does not cancel ethnic differences in fetal growth.

AB - BACKGROUND: We previously described the principal results from an observational, prospective, multicentre, clinical trial of the diagnostic value of optical coherence tomography (OCT) for basal cell carcinoma (BCC) in a clinical setting. In this trial, much additional useful information was gathered that warranted further analysis, presented here. OBJECTIVES: To investigate the influence of candidate diagnostic criteria, OCT image quality, lesion location, and observer confidence and interobserver variability on the diagnostic performance of OCT, and to assess its potential use for diagnosis of BCC subtypes. METHODS: A total of 234 clinically unclear 'pink lesions' were evaluated in three steps: after clinical examination, after adding dermoscopy and after adding OCT. In addition to the diagnoses (including lesion subtype), observers recorded which of 15 diagnostic criteria the OCT image contained, their confidence in the diagnoses, the OCT image quality and the anatomical location of the lesion. RESULTS: Diagnostic performance of OCT did not depend on the lesion's anatomical location. Good OCT image quality was correlated with improved diagnostic performance, but diagnostic performance for lesions with mediocre image quality was still better than by clinical and dermoscopic examination. The main reason for reduced image quality was superficial scales and crusting. Observer confidence in diagnosis was correlated with diagnostic performance. Interobserver diagnostic performance was consistently higher than clinical examination and dermoscopy across all sites. BCC subtype could be determined with moderate accuracy, but further independent image markers are required. CONCLUSION: OCT is useful in the diagnosis of BCC.

PMID- 29193006 TI - A single-institution retrospective cohort study of first-line R-EPOCH chemoimmunotherapy for Richter syndrome demonstrating complex chronic lymphocytic leukaemia karyotype as an adverse prognostic factor. AB - Richter Syndrome, an aggressive lymphoma occurring in patients with chronic lymphocytic leukaemia (CLL), has a generally poor prognosis and anthracycline based chemoimmunotherapy regimens designed to treat de novo diffuse large B-cell lymphoma achieve modest clinical benefit. R-EPOCH (rituximab, etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin) has demonstrated greater activity against aggressive B-cell histologies but has not been studied in Richter Syndrome. We conducted a retrospective cohort study of 46 Richter Syndrome patients treated with first-line R-EPOCH at our institution between 1 January 2006 and 31 May 2014. The median progression-free survival (PFS) was 3.5 months [95% confidence interval (CI): 2.0-7.6] and median overall survival (OS) was 5.9 months (95% CI: 3.2-10.3). Toxicity was high and 30% of patients died without progression or response. Patients with a complex CLL karyotype had significantly shorter PFS and OS (P = 0.005 and P = 0.002, respectively). Multivariable analysis identified complex CLL karyotype as the most significant predictor of decreased survival [Hazard ratio (HR) 2.72, 95% CI: 1.14-6.52, P = 0.025], adjusting for number of prior CLL treatments (P = 0.036). Richter Syndrome patients with complex CLL karyotype experience poor survival with R EPOCH treatment and novel approaches are needed for these patients. In contrast, survival of patients without a complex CLL karyotype was similar to patients with de novo diffuse large B-cell lymphoma.

AB - BACKGROUND: Eye tracking presents a novel tool that could be used to profile skill levels in surgery objectively. The primary aim of this study was to identify differences in gaze behaviour between expert and junior surgeons performing a laparoscopic Roux-en-Y gastric bypass (LRYGB) for obesity. METHODS: This prospective observational study used a lightweight eye-tracking apparatus to determine the difference in gaze behaviours between expert (more than 75 procedures) and junior (75 or fewer procedures) surgeons at defined stages of LRYGB. Primary endpoints were normalized dwell time and fixation frequency. Secondary endpoints were blink rate, maximum pupil size and rate of pupil change. RESULTS: A total of 20 procedures (12 junior, 8 expert) were analysed. Compared with juniors, experts showed a prolonged dwell time on the screen during angle of His dissection (median (range) 91.20 (83.40-94.40) versus 68.95 (59.80-87.60) per cent; P = 0.001), formation of the retrogastric tunnel (91.50 (85.80-95.50) versus 73.60 (34.60-90.50) per cent; P = 0.001) and gastric pouch formation (86.95 (83.60-90.20) versus 67.60 (37.10-80.00) per cent P < 0.001). Juniors had a greater blink frequency throughout all recorded segments (P < 0.010) and had a larger maximum pupil size during all recorded operative segments (P < 0.010). Rate of pupil change was greater in juniors in all analysed segments (P < 0.010). CONCLUSION: These results suggest that experts display more focused attention on significant stimuli, alongside experiencing a reduced mental workload and having increased concentration. This has the potential for future use in validation of surgical skill in high-stakes assessment. PMID- 29193007 TI - Outcome of relapse after allogeneic HSCT in children with ALL enrolled in the ALL SCT 2003/2007 trial. AB - Relapse remains the major cause of treatment failure in children with high-risk acute lymphoblastic leukaemia (ALL) undergoing allogeneic haematopoietic stem cell transplantation (allo-SCT). Prognosis is considered dismal but data on risk factors and outcome are lacking from prospective studies. We analysed 242 children with recurrence of ALL after first allo-SCT enrolled in the Berlin Frankfurt-Munster (BFM) ALL-SCT-BFM 2003 and ALL-SCT-BFM international 2007 studies. Median time from allo-SCT to relapse was 7.7 months; median follow-up from relapse after allo-SCT until last follow-up was 3.4 years. The 3-year event free survival (EFS) was 15% and overall survival (OS) was 20%. The main cause of death was disease progression or relapse (86.5%). The majority of children (48%) received salvage therapy without second allo-SCT, 26% of the children underwent a second allo-SCT and 25% received palliative treatment only. In multivariate analyses, age, site of relapse, time to relapse and type of salvage therapy were identified as significant prognostic factors for OS and EFS, whereas factors associated with first SCT were not statistically significant. Combined approaches incorporating novel immunotherapeutic treatment options and second allo-SCT hold promise to improve outcome in children with post allo-SCT relapse. PMID- 29193009 TI - Do perioperative antibiotics reduce the risk of surgical-site infections following excision of ulcerated skin cancers? A Critically Appraised Topic. AB - AIM: To review the efficacy of perioperative antibiotics in reducing the risk of surgical-site infections (SSIs) following excision of ulcerated skin cancers. SETTING AND DESIGN: Study selection, data extraction and analysis were carried out independently by four authors. Only randomized controlled trials (RCTs) reported in the English language were included. INCLUDED STUDIES: RCTs in the English language in which patients received perioperative topical, intralesional or oral antibiotics for dermatological surgery, including Mohs micrographic surgery in general practice, dermatology or plastic surgery departments, were included. OUTCOME: The proportion of participants developing SSI following excision of skin lesions. RESULTS: Thirteen RCTs were identified from our literature search of PubMed and Embase, which evaluated SSI following use of topical (n = 5), oral (n = 3), intramuscular (n = 2), intravenous (n = 1) and intralesional antibiotics (n = 2) in dermatological surgery. Two RCTs specifically investigated SSIs in ulcerated skin cancer excisions; one RCT investigated the SSI rate following surgical treatment specifically for ulcerated skin cancers in individuals randomized to topical antibiotics vs. oral cephalexin; and one RCT compared intravenous cefazolin with no antibiotic, demonstrating significant reduction in SSI rates for ulcerated tumours (P = 0.04). CONCLUSIONS: The heterogeneity of the RCTs included in this study makes it difficult to make a direct comparison of the outcomes measured. High-quality evidence demonstrating a beneficial effect of the use of perioperative antibiotics to prevent SSI following excision of ulcerated skin cancers is lacking. In the absence of an evidence base, we propose that a well-designed multicentre RCT could evaluate the effect of perioperative antibiotics following excision of ulcerated tumours, and potentially reduce inappropriate antibiotic prescription. PMID- 29193010 TI - Early versus late recurrence of intrahepatic cholangiocarcinoma after resection with curative intent. AB - BACKGROUND: The objective of this study was to investigate the characteristics, treatment and prognosis of early versus late recurrence of intrahepatic cholangiocarcinoma (ICC) after hepatic resection. METHODS: Patients who underwent resection with curative intent for ICC were identified from a multi-institutional database. Data on clinicopathological characteristics, initial operative details, timing and sites of recurrence, recurrence management and long-term outcomes were analysed. RESULTS: A total of 933 patients were included. With a median follow-up of 22 months, 685 patients (73.4 per cent) experienced recurrence of ICC; 406 of these (59.3 per cent) developed only intrahepatic disease recurrence. The optimal cutoff value to differentiate early (540 patients, 78.8 per cent) versus late (145, 21.2 per cent) recurrence was defined as 24 months. Patients with early recurrence had extrahepatic disease more often (44.1 per cent versus 28.3 per cent in those with late recurrence; P < 0.001), whereas late recurrence was more often only intrahepatic (71.7 per cent versus 55.9 per cent for early recurrence; P < 0.001). From time of recurrence, overall survival was worse among patients who had early versus late recurrence (median 10 versus 18 months respectively; P = 0.029). In multivariable analysis, tumour characteristics including tumour size, number of lesions and satellite lesions were associated with an increased risk of early intrahepatic recurrence. In contrast, only the presence of liver cirrhosis was independently associated with an increased likelihood of late intrahepatic recurrence (hazard ratio 1.99, 95 per cent c.i. 1.11 to 3.56; P = 0.019). CONCLUSION: Early and late recurrence after curative resection for ICC are associated with different risk factors and prognosis. Data on the timing of recurrence may inform decisions about the degree of postoperative surveillance, as well as help counsel patients with regard to their risk of recurrence. PMID- 29193011 TI - The life-saving power of policy: Lessons from Kentucky. PMID- 29193013 TI - Lung cancer incidence and the strength of municipal smoke-free ordinances. AB - BACKGROUND: Smoke-free laws reduce disease prevalence. The impact of municipal smoke-free laws on lung cancer incidence in Kentucky was examined. The authors hypothesized that lung cancer incidence rates would be associated with the strength of smoke-free laws. METHODS: This was a secondary analysis of 83,727 Kentucky residents aged >= 50 years who were newly diagnosed with lung cancer from 1995 to 2014. In 2014, 33 municipalities had 1 or more smoke-free laws. County-level characteristics included adult smoking rate, sex, race/ethnicity, income, physician supply, observed radon values, and rurality. RESULTS: Individuals living in communities with comprehensive smoke-free laws were 7.9% less likely than those living in communities without smoke-free protections to be diagnosed with lung cancer. The difference in lung cancer incidence between counties with moderate/weak laws and those without laws was not significant. CONCLUSIONS: Comprehensive smoke-free laws were associated with fewer new cases of lung cancer, whereas weak or moderate smoke-free laws did not confer the same benefit. One hundred percent smoke-free laws, covering all workers and the public with few or no exceptions, may be key in reducing new cases of lung cancer. Cancer 2018;124:374-80.

AB - Our contribution assesses the role of information barriers for patterns of participation in Higher Education (HE) and the related social inequalities. For this purpose, we developed a large-scale clustered randomised experiment involving over 9,000 high school seniors from 62 Italian schools. We designed a counseling intervention to correct student misperceptions of the profitability of HE, that is, the costs, economic returns and chances of success of investments in different tertiary programs. We employed a longitudinal survey to test whether treated students' educational trajectories evolved differently relative to a control group. We find that, overall, treated students enrolled less often in less remunerative fields of study in favour of postsecondary vocational programmes. Most importantly, this effect varied substantially by parental social class and level of education. The shift towards vocational programmes was mainly due to the offspring of low-educated parents; in contrast, children of tertiary graduates increased their participation in more rewarding university fields. Similarly, the redistribution from weak fields to vocational programmes mainly involved the children of the petty bourgeoisie and the working class, while upper class students invested in more rewarding university fields. We argue that the status-maintenance model proposed by Breen and Goldthorpe can explain these socially differentiated treatment effects. Overall, our results challenge the claim that student misperceptions contribute to horizontal inequalities in access to HE. PMID- 29193012 TI - Advances in targeted therapy for acute myeloid leukaemia. AB - In the past few years, research in the underlying pathogenic mechanisms of acute myeloid leukaemia (AML) has led to remarkable advances in our understanding of the disease. Cytogenetic and molecular aberrations are the most important factors in determining response to chemotherapy as well as long-term outcome, but beyond prognostication are potential therapeutic targets. Our increased understanding of the pathogenesis of AML, facilitated by next-generation sequencing, has spurred the development of new compounds in the treatment of AML, particularly the creation of small molecules that target the disease on a molecular level. Various new agents, such as tyrosine kinase inhibitors, immune checkpoint inhibitors, monoclonal or bispecific T-cell engager antibodies, metabolic and pro-apoptotic agents are currently investigated within clinical trials. The highest response rates are often achieved when new molecularly targeted therapies are combined with standard chemotherapy. Presented here is an overview of novel therapies currently being evaluated in AML. PMID- 29193015 TI - The exomic landscape of t(14;18)-negative diffuse follicular lymphoma with 1p36 deletion. AB - Predominantly diffuse t(14;18) negative follicular lymphoma (FL) with 1p36 deletion shows distinctive clinical, morphological and molecular features that distinguish it from classical FL. In order to investigate whether it possesses a unique mutation profile, we performed whole exome sequencing of six well characterised cases. Our analysis showed that the mutational landscape of this subtype is largely distinct from classical FL. It appears to harbour several recurrent mutations, affecting STAT6, CREBBP and basal membrane protein genes with high frequency. Our data support the view that this FL subtype should be considered a separate entity from classical FL. PMID- 29193016 TI - Dupilumab with concomitant topical corticosteroid treatment in adults with atopic dermatitis with an inadequate response or intolerance to ciclosporin A or when this treatment is medically inadvisable: a placebo-controlled, randomized phase III clinical trial (LIBERTY AD CAFE). AB - BACKGROUND: Atopic dermatitis is a chronic inflammatory skin disease that may require systemic therapy. Ciclosporin A (CsA) is a widely used, potent immunosuppressant but it is not effective in all patients with atopic dermatitis, and side-effects limit its use. Dupilumab, a fully human anti-interleukin 4 receptor-alpha monoclonal antibody, inhibits signaling of IL-4 and IL-13, key drivers of Type 2/Th2-mediated inflammation, and is approved in the U.S.A. and the European Union for the treatment of inadequately-controlled moderate-to severe atopic dermatitis in adults. OBJECTIVES: To evaluate efficacy and safety of dupilumab with concomitant topical corticosteroids (TCS) in adults with atopic dermatitis with inadequate response to/intolerance of CsA, or for whom CsA treatment was medically inadvisable. METHODS: In this 16-week, double-blind, randomized, placebo-controlled, phase III trial, patients were randomized 1 : 1 : 1 to subcutaneous dupilumab 300 mg weekly (qw) or every 2 weeks (q2w) or placebo. All received concomitant medium-potency TCS from Week -2 through Week 16; dosage could be tapered if lesions cleared, or stopped for adverse reactions to TCS. RESULTS: In total, 390 patients were screened, 325 were randomized, and 318 completed the trial. Treatment groups had similar baseline characteristics. Significantly more patients in the dupilumab qw + TCS and q2w + TCS groups achieved >= 75% improvement from baseline in the Eczema Area and Severity Index at Week 16 vs. the placebo + TCS group (primary end point) (59.1% and 62.6% vs. 29.6%, respectively; P < 0.001 vs. placebo + TCS, both doses). Other clinical outcomes and atopic dermatitis symptoms were significantly improved in the dupilumab qw + TCS and q2w + TCS groups, including pruritus, pain, sleep disturbance, symptoms of anxiety and depression, and quality of life (QoL). Treatment groups had similar overall rates of adverse events (qw + TCS, q2w + TCS and placebo + TCS groups: 69.1%, 72.0% and 69.4%, respectively) and serious adverse events (1.8%, 1.9% and 1.9%, respectively). Conjunctivitis was more frequent with dupilumab + TCS; skin infections were more frequent with placebo + TCS. CONCLUSIONS: Dupilumab + TCS significantly improved signs and symptoms of atopic dermatitis and QoL in adults with a history of inadequate response to/intolerance of CsA, or for whom CsA treatment was medically inadvisable. No new safety signals were identified. PMID- 29193017 TI - Aggressive lymphomas of the elderly: the DEVEC metronomic chemotherapy schedule fits the unfit.

PMID- 29193018 TI - Obesity negatively impacts outcome in elderly female patients with aggressive B cell lymphomas treated with R-CHOP: results from prospective trials of the German high grade non-Hodgkin's lymphoma trial group. AB - To study if obesity is a risk factor in elderly patients (>60 years) with aggressive B-cell lymphoma, the outcomes of 576 elderly patients treated with rituximab in the RICOVER-60 trial were analysed in a retrospective study with regard to body mass index (BMI) and gender. Of the 576 patients, 1% had low body weight (BMI < 18.5), 38% were normal weight (18.5 <= BMI < 25), 42% were overweight (25 <= BMI < 30) and 19% were obese (BMI >= 30). Event-free (EFS), progression-free (PFS) and overall survival (OS) according to BMI showed no significant differences for all and for male patients. EFS (P = 0.041), PFS (P = 0.038) and OS (P = 0.031) were significantly better for female non-obese patients. A multivariate analysis adjusted for International Prognostic Index risk factors confirmed these results, with the following hazard ratios (HR) for obesity (BMI >= 30) for EFS/PFS/OS: all patients - 1.4/1.4/1.4 (not significant); male patients - 1.2/1.2/1.0 (not significant) and female patients - 1.7 (P = 0.032)/1.9 (P = 0.022)/2.0 (P = 0.017). In conclusion, obesity is a risk factor that influences treatment outcome in elderly female patients with aggressive B cell lymphoma treated with R-CHOP (rituximab + cyclophosphamide, doxorubicin, vincristine, prednisolone). The inferior outcomes in obese female patients may be due to faster rituximab clearance in obese females. PMID- 29193019 TI - Prospective subgroup analyses of the randomized MCL-002 (SPRINT) study: lenalidomide versus investigator's choice in relapsed or refractory mantle cell lymphoma. AB - In the mantle cell lymphoma (MCL)-002 study, lenalidomide demonstrated significantly improved median progression-free survival (PFS) compared with investigator's choice (IC) in patients with relapsed/refractory MCL. Here we present the long-term follow-up data and results of preplanned subgroup exploratory analyses from MCL-002 to evaluate the potential impact of demographic factors, baseline clinical characteristics and prior therapies on PFS. In MCL 002, patients with relapsed/refractory MCL were randomized 2:1 to receive lenalidomide (25 mg/day orally on days 1-21; 28-day cycles) or single-agent IC therapy (rituximab, gemcitabine, fludarabine, chlorambucil or cytarabine). The intent-to-treat population comprised 254 patients (lenalidomide, n = 170; IC, n = 84). Subgroup analyses of PFS favoured lenalidomide over IC across most characteristics, including risk factors, such as high MCL International Prognostic Index score, age >=65 years, high lactate dehydrogenase (LDH), stage III/IV disease, high tumour burden, and refractoriness to last prior therapy. By multivariate Cox regression analysis, factors associated with significantly longer PFS (other than lenalidomide treatment) included normal LDH levels (P < 0.001), nonbulky disease (P = 0.045), <3 prior antilymphoma treatments (P = 0.005), and >=6 months since last prior treatment (P = 0.032). Overall, lenalidomide improved PFS versus single-agent IC therapy in patients with relapsed/refractory MCL, irrespective of many demographic factors, disease characteristics and prior treatment history. PMID- 29193021 TI - Bendamustine, bortezomib and rituximab produces durable complete remissions in patients with previously untreated, low grade lymphoma. AB - This Phase II trial evaluated the efficacy of bendamustine, bortezomib and rituximab in patients with previously untreated low-grade lymphoma. Eligible patients had low grade lymphoma with no previous systemic disease treatment. Treatment for all patients was given in 28-day cycles for a maximum of 6 cycles. Patients received rituximab 375 mg/m2 intravenously (IV) on days 1, 8 and 15 of cycle 1 and day 1 of cycles 2-6; bendamustine 90 mg/m2 IV on days 1 and 2; and bortezomib 1.6 mg/m2 IV on days 1, 8 and 15. Patients were permitted to begin maintenance treatment with rituximab 6 months after completion of study treatment and after 6-month follow-up assessments had been conducted. Fifty-four eligible patients were enrolled. The most common grade 3/4 toxicities were leucopenia (28%), neutropenia (30%) and lymphopenia (17%). There were no treatment-related deaths and 1 unrelated death on study (embolic stroke). The overall response rate was 94% for all patients. The median follow-up was 54 months. Kaplan-Meier estimates of progression-free survival and overall survival at 36 months were 75% and 88%, respectively. The treatment regimen was well tolerated and produced high response rates. Further study of this regimen in patients with previously untreated lymphoma is warranted. PMID- 29193022 TI - Experimental study of delivery of humidified-warm carbon dioxide during open abdominal surgery. AB - BACKGROUND: The aim of this study was to monitor the effect of humidified-warm carbon dioxide (HWCO2 ) delivered into the open abdomen of mice, simulating laparotomy. METHODS: Mice were anaesthetized, ventilated and subjected to an abdominal incision followed by wound retraction. In the experimental group, a diffuser device was used to deliver HWCO2 ; the control group was exposed to passive air flow. In each group of mice, surgical damage was produced on one side of the peritoneal wall. Vital signs and core temperature were monitored throughout the 1-h procedure. The peritoneum was closed and mice were allowed to recover for 24 h or 10 days. Tumour cells were delivered into half of the mice in each cohort. Tissue was then examined using scanning electron microscopy and immunohistochemistry. RESULTS: Passive air flow generated ultrastructural damage including mesothelial cell bulging/retraction and loss of microvilli, as assessed at 24 h. Evidence of surgical damage was still measurable on day 10. HWCO2 maintained normothermia, whereas open surgery alone led to hypothermia. The degree of tissue damage was significantly reduced by HWCO2 compared with that in controls. Peritoneal expression of hypoxia inducible factor 1alpha and vascular endothelial growth factor A was lowered by HWCO2 . These effects were also evident at the surgical damage sites, where protection from tissue trauma extended to 10 days. HWCO2 did not reduce tumorigenesis in surgically damaged sites compared with passive air flow. CONCLUSION: HWCO2 diffusion into the abdomen in the context of open surgery afforded tissue protection and accelerated tissue repair in mice, while preserving normothermia. Surgical relevance Damage to the peritoneum always occurs during open abdominal surgery, by exposure to desiccating air and by mechanical trauma/damage owing to the surgical intervention. Previous experimental studies showed that humidified-warm carbon dioxide (HWCO2 ) reduced peritoneal damage during laparoscopic insufflation. Additionally, this intervention decreased experimental peritoneal carcinomatosis compared with the use of conventional dry-cold carbon dioxide. In the present experimental study, the simple delivery of HWCO2 into the open abdomen reduced the amount of cellular damage and inflammation, and accelerated tissue repair. Sites of surgical intervention serve as ideal locations for cancer cell adhesion and subsequent tumour formation, but this was not changed measurably by the delivery of HWCO2 .

AB - An impaired expression of alpha-defensins (alpha-Defs) in the ileal mucosa and, conversely, increased levels in plasma, have been reported in Crohn's disease (CD). However, the specificity and correlation of these findings with the degree of inflammation are unclear. We aimed to characterize the concentration and utility of ileal and plasma alpha-Defs in CD and to analyse a potential epigenetic mechanism of alpha-Def expression. Peripheral blood samples and ileal biopsies were obtained from patients at disease onset (aCD), from those who achieved remission (iCD) and from two control groups (healthy controls and non-CD aetiology ileitis patients). Plasma alpha-Defs 1-3 and 4 were detected by enzyme linked immunosorbent assay (ELISA); alpha-Def 5 by immunolocalization. Methylation analysis of the alpha-Def 5 gene was performed using the MassARRAY EpiTYPER system. Plasma alpha-Defs 1-3 concentrations were significantly higher in aCD with ileal involvement (L1, L3) versus iCD or the control groups. The alpha-Defs 1-3 concentrations were also similar to healthy controls in patients with non-CD ileitis. There was a significant positive correlation between plasma alpha-Defs 1-3 levels in aCD and the endoscopic index, as well as with C-reactive protein (CRP) levels. The immunopositivity scoring showed significantly reduced alpha-Def 5 expression in ileal inflamed (aCD) versus non-inflamed mucosa (iCD and healthy controls). The alpha-Def 5 gene showed a higher methylation status in CD patients than controls, regardless of the inflammation. Plasma alpha-Defs 1-3 concentrations correlate with the degree of inflammation and appear to be specific biomarkers of ileal-CD at diagnosis. Ileal alpha-Def 5 expression is down-regulated permanently by methylation. PMID- 29193024 TI - Weathering of Oil in a Surficial Aquifer. AB - The composition of crude oil in a surficial aquifer was determined in two locations at the Bemidji, MN, spill site. The abundances of 71 individual hydrocarbons varied within 16 locations sampled. Little depletion of these hydrocarbons (relative to the pipeline oil) occurred in the first 10 years after the spill, whereas losses of 25% to 85% of the total measured hydrocarbons occurred after 30 years. The C6-30 n-alkanes, toluene, and o-xylene were the most depleted hydrocarbons. Some hydrocarbons, such as the n-C10-24 cyclohexanes, tri- and tetra- methylbenzenes, acyclic isoprenoids, and naphthalenes were the least depleted. Benzene was detected at every sampling location 30 years after the spill. Degradation of the oil led to increases in the percent organic carbon and in the delta 13 C of the oil. Another method of determining hydrocarbon loss was by normalizing the total measured hydrocarbon concentrations to that of the most conservative analytes. This method indicated that the total measured hydrocarbons were depleted by 47% to 77% and loss of the oil mass over 30 years was 18% to 31%. Differences in hydrocarbon depletion were related to the depth of the oil in the aquifer, local topography, amount of recharge reaching the oil, availability of electron acceptors, and the presence of less permeable soils above the oil. The results from this study indicate that once crude oil has been in the subsurface for a number of years there is no longer a "starting oil concentration" that can be used to understand processes that affect its fate and the transport of hydrocarbons in groundwater.

Thus, humanized animal models could be useful to bridge the gap between preclinical and clinical pharmacology and gain relevant insight into the determinants of drug disposition and drug-drug interaction (DDI). PMID- 29193026 TI - Respiratory sinus arrhythmia: Modeling longitudinal change from 6 weeks to 2 years of age among low-income Mexican Americans. AB - Parasympathetically-mediated heart rate variability (HRV), commonly indexed via respiratory sinus arrhythmia (RSA), is theorized to support the physiological regulation of emotion; however, little is known about the trajectory of change in resting RSA across early development among high-risk populations for whom emotion regulation is crucial. This study characterized resting RSA change from 6 weeks to 2 years of age among 312 low-income Mexican American infants. RSA was assessed longitudinally at 6, 12, 18, 24, 52, 78, and 104 weeks of age. On average, resting RSA increased as infants aged, and this change accelerated over time. There was significant variance between infants in resting RSA at 6 weeks of age, and in the slope, and acceleration of resting RSA change. Intraclass correlation among infants' resting RSA measures was minimal, indicating that resting RSA may not be "trait-like" during infancy. Results characterize early RSA development among a high-risk sample, which can inform theoretical understanding of the development of emotional, and behavioral self-regulation in a high-risk population, as well as efforts to promote wellbeing across early childhood. PMID- 29193028 TI - Connectivity in a Karst System Using Electrical Resistivity Tomography and Network Theory. AB - The Ring of Cenotes (RC) is an alignment of numerous cenotes (sinkholes) in a semicircular form (with a radius of 100 km) located in northwestern Yucatan, Mexico. The formation roughly coincides with a concentric ring that corresponds to a buried structure, which has been identified as the product of a meteor impact, known as the Chicxulub crater. Secondary permeability generated by the fracturing and faulting of the sedimentary sequence in the Chicxulub crater has favored the karstification process and therefore the development of underground rivers that transport water from the mainland to the sea. This study implements the network theory to study the hydrological connectivity between a group of 11 cenotes within the RC. Eight electrical resistivity tomography transects were used as an empirical basis. Each transect was acquired directly in the field using the SuperSting R1/IP equipment with a dipole-dipole configuration. An adapted version of the reliability algorithm for communication networks was used as a theoretical model. We found evidence of the existence of water cavities in the study area. We made a network from the data and assigned connection probabilities among cenotes as a function of the separation length and the number of water cavities, as well as their size. PMID- 29193029 TI - Recent progress in understanding and manipulating haemoglobin switching for the haemoglobinopathies. AB - The major beta-haemoglobinopathies, sickle cell disease and beta-thalassaemia, represent the most common monogenic disorders worldwide and a steadily increasing global disease burden. Allogeneic haematopoietic stem cell transplantation, the only curative therapy, is only applied to a small minority of patients. Common clinical management strategies act mainly downstream of the root causes of disease. The observation that elevated fetal haemoglobin expression ameliorates these disorders has motivated longstanding investigations into the mechanisms of haemoglobin switching. Landmark studies over the last decade have led to the identification of two potent transcriptional repressors of gamma-globin, BCL11A and ZBTB7A. These regulators act with additional trans-acting epigenetic repressive complexes, lineage-defining factors and developmental programs to silence fetal haemoglobin by working on cis-acting sequences at the globin gene loci. Rapidly advancing genetic technology is enabling researchers to probe deeply the interplay between the molecular players required for gamma-globin (HBG1/HBG2) silencing. Gene therapies may enable permanent cures with autologous modified haematopoietic stem cells that generate persistent fetal haemoglobin expression. Ultimately rational small molecule pharmacotherapies to reactivate HbF could extend benefits widely to patients. PMID- 29193030 TI - Ankle muscle tenotomy does not alter ankle flexor muscle recruitment bias during locomotor-related repetitive limb movement in late-stage chick embryos. AB - In ovo, late-stage chick embryos repetitively step spontaneously, a locomotor related behavior also identified as repetitive limb movement (RLM). During RLMs, there is a flexor bias in recruitment and drive of leg muscle activity. The flexor biased activity occurs as embryos assume an extremely flexed posture in a spatially restrictive environment 2-3 days before hatching. We hypothesized that muscle afferent feedback under normal mechanical constraint is a significant input to the flexor bias observed during RLMs on embryonic day (E) 20. To test this hypothesis, muscle afference was altered either by performing a tenotomy of ankle muscles or removing the shell wall restricting leg movement at E20. Results indicated that neither ankle muscle tenotomy nor unilateral release of limb constraint by shell removal altered parameters indicative of flexor bias. We conclude that ankle muscle afference is not essential to ankle flexor bias characteristic of RLMs under normal postural conditions at E20.

METHOD: Studies of infants born preterm with MRI earlier than 36 weeks postmenstrual age and quantitative motor data or a diagnosis of CP at or beyond 1 year corrected age were identified. Study details were extracted and meta-analyses performed where possible. Quality of included studies was evaluated with the QUADAS-2 (a revised tool for the quality assessment of diagnostic accuracy studies). RESULTS: Thirty-one articles met the inclusion criteria, five of which reported diagnostic accuracy and five reported data sufficient for calculation of diagnostic accuracy. Early structural MRI global scores detected a later diagnosis of CP with a pooled sensitivity of 100% (95% confidence interval [CI] 86-100) and a specificity of 93% (95% CI 59-100). Global structural MRI scores determined adverse motor outcomes with a pooled sensitivity of 89% (95% CI 44-100) and a specificity of 98% (95% CI 90-100). White matter scores determined adverse motor outcomes with a pooled sensitivity of 33% (95% CI 20-48) and a specificity of 83% (95% CI 78-88). INTERPRETATION: Early structural MRI has reasonable sensitivity and specificity to determine adverse motor outcomes and CP in infants born preterm. Greater reporting of diagnostic accuracy in studies examining relationships with motor outcomes and CP is required to facilitate clinical utility of early MRI. WHAT THIS PAPER ADDS: Early magnetic resonance imaging (MRI) has reasonable sensitivity and specificity to determine later adverse motor outcomes and cerebral palsy (CP). Detection of infants who progressed to CP was stronger than motor outcomes. Global MRI scores determined adverse motor outcomes more accurately than white matter scores. Few studies report diagnostic accuracy of early MRI findings. Diagnostic accuracy is required to draw clinically meaningful conclusions from early MRI studies.

AB - Biallelic mutations in the SLC30A10 gene cause an inborn error of Mn metabolism characterized by hypermanganesemia, polycythemia, early-onset dystonia, and liver cirrhosis (HMDPC). To date, only 14 families from various ethnic groups have been reported. Here, we describe 10 patients from 7 unrelated Egyptian families with HMDPC. Markedly elevated blood Mn levels, the characteristic basal ganglia hyperintensity on T1-weighted images, and variable degrees of extrapyramidal manifestations with or without liver disease were cardinal features in all patients. Eight patients presented with striking early diseased onset (<=2 years). Unexpectedly, early hepatic involvement before the neurological regression was noted in 3 patients. Mutational analysis of SLC30A10 gene revealed 6 novel homozygous mutations (c.77T > C (p.Leu26Pro), c.90C > G (p.Tyr30*), c.119A > C (p.Asp40Ala), c.122_124delCCT (p.Ser41del), c.780_782delCAT (p.Iso260del) and c.957 + 1G > C). Treatment using 2,3 dimercaptosuccinic acid as a manganese chelating agent showed satisfactory results with improvement of biochemical markers, hepatic manifestations and relative amelioration of the neurological symptoms. Our findings present a large cohort of patients with HMDPC from same ethnic group. The majority of our patients showed severe and early presentation with clear phenotypic variability among sibship. Moreover, we extend the phenotypic and mutational spectrum and emphasize the importance of early diagnosis and treatment of this potentially fatal disorder. PMID- 29193033 TI - Designing a cancer therapeutic peptide by combining the mitochondrial targeting domain of Noxa and ErbB2-targeting moieties. AB - Many anticancer drugs target epidermal growth factor receptors to inhibit receptor tyrosine kinases and tumor growth. Here, we show that an ErbB2-targeting pronecrotic peptide (KWSY:MTD) selectively kills tumor cells expressing ErbB2 in vitro. An antibody against ErbB2 inhibits KWSY:MTD-induced cell death. KWSY:MTD causes membrane permeability which allows propidium iodide entry into the cytosol and the release of HMGB1 into the media, indicative of necrosis. Mitochondrial swelling occurs in response to KWSY:MTD. Moreover, in vivo analysis using a mouse model shows that KWSY:MTD partially suppressed growth in tumor tissue bearing ErbB2-expressing cells, but did not have obvious toxicity in mouse liver or kidney tissue. Taken together, KWSY:MTD has potential as an ErbB2-targeting anticancer drug.

PMID- 29193038 TI - Emerging Clinical Importance of Hepatic Organic Cation Transporter 1 (OCT1) in Drug Pharmacokinetics, Dynamics, Pharmacogenetic Variability, and Drug Interactions. AB - Hepatic organic cation transporter 1 (OCT1) can be a determinant of drug clearance and distribution, which can impact drug exposure and response. OCT1 was shown recently to be the rate-determining step in the clearance of several drugs in humans, and thereby a mechanism of pharmacogenetic variability and drug-drug interactions (DDIs). OCT1 mediates metformin distribution to the liver (key biophase). As OCT1 modulation impacts metformin response, but not pharmacokinetics (PK), metformin DDI studies require pharmacodynamic endpoint(s) to inform rational metformin dose adjustment. PMID- 29193036 TI - CXCL4 is a novel inducer of human Th17 cells and correlates with IL-17 and IL-22 in psoriatic arthritis. AB - CXCL4 regulates multiple facets of the immune response and is highly upregulated in various Th17-associated rheumatic diseases. However, whether CXCL4 plays a direct role in the induction of IL-17 production by human CD4+ T cells is currently unclear. Here, we demonstrated that CXCL4 induced human CD4+ T cells to secrete IL-17 that co-expressed IFN-gamma and IL-22, and differentiated naive CD4+ T cells to become Th17-cytokine producing cells. In a co-culture system of human CD4+ T cells with monocytes or myeloid dendritic cells, CXCL4 induced IL-17 production upon triggering by superantigen. Moreover, when monocyte-derived dendritic cells were differentiated in the presence of CXCL4, they orchestrated increased levels of IL-17, IFN-gamma, and proliferation by CD4+ T cells. Furthermore, the CXCL4 levels in synovial fluid from psoriatic arthritis patients strongly correlated with IL-17 and IL-22 levels. A similar response to CXCL4 of enhanced IL-17 production by CD4+ T cells was also observed in patients with psoriatic arthritis. Altogether, we demonstrate that CXCL4 boosts pro inflammatory cytokine production especially IL-17 by human CD4+ T cells, either by acting directly or indirectly via myeloid antigen presenting cells, implicating a role for CXCL4 in PsA pathology.

PMID- 29193037 TI - Model answers: Rational application of murine models in arthritis research. AB - Advances in targeted immune therapeutics have profoundly improved clinical outcomes for patients with inflammatory arthropathies particularly rheumatoid arthritis. The landscape of disease that is observed and the treatment outcomes desired for the future have also progressed. As such there is an increasing move away from traditional models of end-stage, chronic disease with recognition of the need to consider the earliest phases of pathogenesis as a target for treatment leading to resolution and/or cure. In order to continue the discovery process and enhance our understanding of disease and treatment, we therefore need to continuously revisit the animal models we employ and assess their relevance and utility in the light of contemporary therapeutic goals. In this review, we highlight the areas where we consider new developments in animal models and their application are most required. Thus, we have contextualised the relevant mouse models and their use within the current concepts of human inflammatory arthritis pathogenesis and highlight areas of need.

PMID- 29193041 TI - Early nurse attrition in New Zealand and associated policy implications. AB - AIM: To examine the factors contributing to nurses choosing to exit the nursing profession before retirement age. BACKGROUND: Population growth, ageing and growing demand for health services mean increased demand for nurses. Better retention could help meet this demand, yet little work has been done in New Zealand to understand early attrition. METHODS: An online survey of registered and enrolled nurses and nurse practitioners who had left nursing was used. This study reports analysis of responses from 285 ex-nurses aged under 55. FINDINGS: The primary reasons nurses left the profession were as follows: workplace concerns; personal challenges; career factors; family reasons; lack of confidence; leaving for overseas; unwillingness to complete educational requirements; poor work-life balance; and inability to find suitable nursing work. Most nurses discussed their intentions to leave with a family member or manager and most reported gaining transferrable skills through nursing. CONCLUSIONS: Nurses leave for many reasons. Implementing positive practice environments and individualized approaches to retaining staff may help reduce this attrition. Generational changes in the nature of work and careers mean that nurses may continue to leave the profession sooner than anticipated by policymakers. IMPLICATIONS FOR POLICY: If the nursing workforce is to be able to meet projected need, education, recruitment and retention policies must urgently address issues leading to early attrition. In particular, policies improving the wider environmental context of nursing practice and ensuring that working environments are safe and nurses are well supported must be developed and implemented. Equally, national nursing workforce planning must take into account that nursing is no longer viewed as a career for life.

PMID- 29193043 TI - The Role of Negative Affect on Headache-Related Disability Following Traumatic Physical Injury. AB - OBJECTIVE: Acute postinjury negative affect (NA) may contribute to headache pain following physical injury. Early psychiatric-headache comorbidity conveys increased vulnerability to chronic headache-related disability and impairment. Yet, it is unknown whether NA is involved in the transition to chronic headache related-disability after injury. This prospective observational study examined the role of acute postinjury NA on subacute and chronic headache-related disability above and beyond nonpsychiatric factors. METHODS: Eighty adult survivors of single-incident traumatic physical injury were assessed for negative affect (NA): a composite of depression and anxiety symptoms, and symptoms of posttraumatic stress disorder (PTSS) during the acute 2-week postinjury phase. NA was examined as the primary predictor of subacute (6-week) and chronic (3-month) headache-related disability; secondary analyses examined whether the individual NA components differentially impacted the outcomes. RESULTS: Hierarchical linear regression confirmed NA as a unique predictor of subacute (Cohen's f 2 = 0.130; P = .005) and chronic headache related-disability (Cohen's f 2 = 0.160; P = .004) beyond demographic and injury-related factors (sex, prior headaches, and closed head injury). Upon further analysis, PTSS uniquely predicted greater subacute (Cohen's f 2 = 0.105; P = .012) and chronic headache-related disability (Cohen's f 2 = 0.103; P = .022) above and beyond demographic and injury-related factors, depression, and anxiety. Avoidance was a robust predictor of subacute headache impairment (explaining 15% of the variance) and hyperarousal was a robust predictor of chronic headache impairment (10% of the variance). CONCLUSION: Although NA consistently predicted headache-related disability, PTSS alone was a unique predictor above and beyond nonpsychiatric factors, depression, and anxiety. These results are suggestive that early treatment of acute postinjury PTSS may correlate with reductions in disability and negative physical health sequelae associated with PTSS and chronic headache. PMID- 29193044 TI - Accumulation of rest deficiency precedes sudden death of epileptic Kv1.1 knockout mice, a model of sudden unexpected death in epilepsy. AB - OBJECTIVE: Chronic sleep deficiency is associated with early mortality. In the epileptic population, there is a higher prevalence of sleep disorders, and individuals with severe refractory epilepsy are at greater risk of premature mortality than the general population. Sudden unexpected death in epilepsy affects 1:1000 cases of epilepsy each year. Ketogenic diet (KD) treatment is one of the few effective options for refractory seizures. Despite KD reducing seizures and increasing longevity in Kv1.1 knockout (KO) mice, they still succumb to sudden death. This study aims to determine whether (1) the rest profiles of KO and KD-treated KO (KOKD) mice resemble each other as a function of either age or proximity to death and (2) the timing of death correlates with acute or chronic changes in rest. METHODS: Noninvasive actimetry was used to monitor rest throughout the lives of KO and wild-type (WT) littermates administered standard diet or KD. RESULTS: As KO mice age, rest is reduced (P < .0001). Rest is significantly improved in KDKO mice (P < .0001), resembling WT values at several ages. When age is removed as a variable and data are realigned to the day of death, the rest profiles of KO and KOKD groups worsen to similar degrees as a function of proximity to death. The amount of rest acutely is not sensitive to the timing of death, whereas chronic rest deficiency profiles (10-15 days prior to death) of both groups were indistinguishable. Chronic accumulation of rest deficiency over the final 15 days was associated with 75% of deaths. SIGNIFICANCE: Our data suggest that the accumulated rest deficiency is associated with sudden death in Kv1.1 KO mice. These data (1) support the proposed clinical hypothesis that chronic sleep deficiency may be associated with early mortality in epileptic patients and (2) warrant future preclinical and clinical studies on sleep monitoring in epileptic patients. PMID- 29193046 TI - Measurement invariance of the Belief in a Zero-Sum Game scale across 36 countries. AB - In this paper, we examined the psychometric properties of cross-cultural validation and replicability (i.e. measurement invariance) of the Belief in a Zero-Sum Game (BZSG) scale, measuring antagonistic belief about interpersonal relations over scarce resources. The factorial structure of the BZSG scale was investigated in student samples from 36 countries (N = 9907), using separate confirmatory factor analyses (CFAs) for each country. The cross-cultural validation of the scale was based on multigroup confirmatory factor analyses (MGCFA). The results confirmed that the scale had a one-factor structure in all countries, in which configural and metric invariance between countries was confirmed. As a zero-sum belief about social relations perceived as antagonistic, BZSG is an important factor related to, for example, social and international relations, attitudes toward immigrants, or well-being. The paper proposes different uses of the BZSG scale for cross-cultural studies in different fields of psychology: social, political, or economic. PMID- 29193045 TI - Waist circumference and risk of breast cancer in Korean women: A nationwide cohort study. AB - Although postmenopausal breast cancer (BC) risk has been linked to adiposity, associations between adiposity and premenopausal BC remain unclear. To address this question, we investigated the association of BC risk with measures of adiposity, including body mass index (BMI) and waist circumference (WC), in a large cohort of Asian women. We used a nationwide cohort of adult Korean women selected from the National Health Insurance Corporation database merged with national health examination data from 2009 to 2015. A total of 11,227,948 women were tracked to retrospectively identify incident cases of BC. Our analysis used Cox proportional hazards models to calculate hazard ratios and assess the association of BC risk with BMI and/or WC in both pre- and postmenopausal women. BMI and WC were robustly associated with increased risk for postmenopausal BC (ptrend <0.001 for both BMI and WC) but not with premenopausal BC. Association between WC and premenopausal BC was only statistically significant when considering BMI (ptrend =0.044). In contrast, postmenopausal BC was negatively associated with WC when considering BMI (ptrend =0.011). In premenopausal women, WC may predict increased BC risk when considering BMI. However, in postmenopausal women, WC is not superior to BMI as an indicator of BC risk. PMID- 29193047 TI - Prediction of Groundwater Level in Ardebil Plain Using Support Vector Regression and M5 Tree Model. AB - The Ardebil plain, which is located in northwest Iran, has been faced with a recent and severe decline in groundwater level caused by a decrease of precipitation, successive long-term droughts, and overexploitation of groundwater for irrigating the farmlands. Predictions of groundwater levels can help planners to deal with persistent water deficiencies. In this study, the support vector regression (SVR) and M5 decision tree models were used to predict the groundwater level in Ardebil plain. The monthly groundwater level data from 24 piezometers for a 17-year period (1997 to 2013) were used for training and test of models. The model inputs included the groundwater levels of previous months, the volume of entering precipitation into every cell, and the discharge of wells. The model output was the groundwater level in the current month. In order to evaluate the performance of models, the correlation coefficient (R) and the root-mean-square error criteria were used. The results indicated that both SVR and M5 decision tree models performed well for the prediction of groundwater level in the Ardebil plain. However, the results obtained from the M5 decision tree model are more straightforward, more easily applied, and simpler to interpret than those from the SVR. The highest accuracy was obtained using the SVR model to predict the groundwater level from the Ghareh Hasanloo and Khalifeloo piezometers with R = 0.996 and R = 0.983, respectively.

PMID- 29193049 TI - Development and validation of Indian Affective Picture Database. AB - Since culturally salient stimuli for emotion recognition are scarce in India, we developed and validated a set of 140 coloured pictures of six basic emotions along with a neutral expression. The expressions were posed by four expressers, two males and two females, with mean age of 25.25 (SD 3.77) years. The expressions were captured from five different angles keeping the background uniform. These pictures were shown to 350 undergraduates who labelled the emotion and rated their intensity. The mean biased hit rate was 93.02 (SD 7.33) and mean unbiased hit rate was .519 (SD .015). Within subjects ANOVA revealed significant main effect of emotion (F(1, 6) = 7.598, p < .001). The t-test value (23.116, p < .001) shows that the given emotion was identified correctly by participants beyond chance factors. The mean intensity rating was 5.94 (SD .77). Overall, the results reveal that the pictures are a valid set of affective stimuli. PMID- 29193050 TI - Antagonistic Relationship Between VEP Potentiation and Gamma Power in Visual Snow Syndrome. AB - OBJECTIVE: Using a "double-pulse" adaptation paradigm, in which two stimuli are presented in quick succession, this study examines the neural mechanisms underlying potentiation of the visual evoked potential (VEP) in visual snow syndrome. BACKGROUND: Visual snow is a persistent visual disturbance characterized by rapid flickering dots throughout the visual field. Like the related condition of migraine with aura, visual snow has been hypothesized to arise from abnormal neuronal responsiveness, as demonstrated by a lack of typical VEP habituation to repeated visual stimulation. Yet the exact neural mechanisms underlying this effect remain unclear. Previous "double-pulse" experiments suggest that typical VEP habituation reflects disruptive gamma-band (50-70 Hz) neural oscillations, possibly driven by inhibitory interneurons. Given that migraine has been associated with reduced cortical inhibition, we propose here that visual snow may likewise reflect diminished inhibitory activity, resulting in decreased gamma power following initial visual stimulation and concomitant potentiation of the subsequent VEP response. METHODS: We compared VEP responses to double-pulse adaptation in a 22-year-old man with a 2-year history of visual snow versus a group of age- and gender-matched controls (N = 5). The patient does not have a comorbid diagnosis of episodic migraine or migraine with aura, and controls had no personal or family history of migraine. RESULTS: In contrast to the pattern of habituation observed in controls, visual snow was associated with persistent potentiation of the VEP response. Consistent with our predictions, time-frequency analysis revealed reduced gamma-band power following the initial stimulus in visual snow relative to controls. CONCLUSIONS: These results support an antagonistic interplay between gamma power and rapid neural adaptation, shedding new light on the neural mechanisms of VEP potentiation in visual snow. PMID- 29193052 TI - Association Between Migraine and Suicidal Behaviors: A Nationwide Study in the USA. AB - BACKGROUND: Recent studies show migraineurs are at an increased risk of developing suicidal behaviors, even after controlling for comorbid depression. However, previous research has not examined the impact of psychiatric mood disorders on suicidal behaviors in migraineurs within a nationally representative sample. OBJECTIVE: A cross-sectional study was used to investigate the association between migraine and suicidal behaviors and determine whether psychiatric comorbidities modify this association in a nationwide inpatient cohort. METHODS: We analyzed the Nationwide Inpatient Sample of hospitalizations compiled from USA billing data. Migraine, suicidal behaviors, and psychiatric disorders were identified based on the International Classification of Diseases, 9th Revision, Clinical Modification diagnosis codes from hospitalization discharges (2007-2012). Weighted national estimates were used to estimate odds ratios (OR) and 95% confidence intervals (CI). RESULTS: 156,172,826 hospitalizations were included, of which 1.4% had a migraine diagnosis and 1.6% had a diagnosis of suicidal behavior. Migraineurs had a 2.07-fold increased odds of suicidal behaviors (95%CI: 1.96-2.19) compared with non-migraineurs. We repeated analyses after stratifying by depression, anxiety, or posttraumatic stress disorder (PTSD). Among hospitalizations with depression, migraine was associated with a 20% reduced odds of suicidal behaviors (95%CI: 0.76-0.85). Among hospitalizations without depression, migraine was associated with 2.35-fold increased odds of suicidal behaviors (95%CI: 2.20-2.51). In stratified analyses, we noted that among hospitalizations with anxiety, migraineurs had slightly increased odds of suicidal behaviors (OR: 1.07, 95%CI: 1.02-1.13). Among hospitalizations without anxiety, migraine was associated with a 2.06-fold increased odds of suicidal behaviors (95%CI: 1.94-2.20). Similarly, in analyses stratified by PTSD, migraine was not associated with an increased risk of suicidal behaviors (OR: 1.00, 95%CI: 0.94-1.07) among those with PTSD. However, the odds of suicidal behaviors were increased among hospitalizations without PTSD (OR: 1.95, 95%CI: 1.84-2.08). CONCLUSION: Chronic conditions that do not affect the current hospitalization may not have been reported. The presence of psychiatric diagnoses influences associations of suicidal behaviors with migraine in a national inpatient sample. Migraineurs with diagnosed comorbid psychiatric disorders may be receiving care that mitigates their risk for suicidal behaviors.

AB - OBJECTIVES: The chronic and progressive nature of diabetes is usually associated with micro- and macrovascular complications where failure of pancreatic beta-cell function and a general condition of hyperglycaemia is created. One possible factor is failure of the patient to comply with and adhere to the prescribed insulin due to the inconvenient administration route. This review summarizes the rationale for oral insulin administration, existing barriers and some counter strategies trialled. KEY FINDINGS: Oral insulin mimics the physiology of endogenous insulin secreted by pancreas. Following the intestinal absorption of oral insulin, it reaches the liver at high concentration via the portal vein. Oral insulin on the other hand has the potential to protect pancreatic beta-cells from autoimmune destruction. Structural modification, targeting a particular tissue/receptor, and the use of innovative pharmaceutical formulations such as nanoparticles represent strategies introduced to improve oral insulin bioavailability. They showed promising results in overcoming the hurdles facing oral insulin delivery, although delivery is far from ideal. SUMMARY: The use of advanced pharmaceutical technologies and further research in particulate carrier system delivery predominantly nanoparticle utilization would offer useful tools in delivering insulin via the oral route which in turn would potentially improve diabetic patient compliance to insulin and the overall management of diabetes. PMID- 29193051 TI - Interaction between tobacco smoking and hepatitis B virus infection on the risk of liver cancer in a Chinese population. AB - Although tobacco smoking has been reported as a risk factor for liver cancer, few studies have specifically explored the association among Chinese females and the potential interaction between smoking and other risk factors. A population-based case-control study was conducted and 2,011 liver cancer cases and 7,933 healthy controls were enrolled in Jiangsu, China from 2003 to 2010. Epidemiological data were collected, and serum hepatitis B surface antigen (HBsAg) and anti-HCV antibody were measured. Unconditional logistic regression was used to examine association and potential interaction, while semi-Bayes (SB) method was employed to make estimates more conservative. The prevalence of serum HBsAg positivity was 43.2% among cases and 6.5% among controls. The adjusted odds ratios (OR) for ever smoking were 1.62 (95% confidence interval [CI]: 1.33-1.96) among male and 0.82 (95% CI: 0.53-1.26) among female. Age at first cigarette, duration of smoking and pack-years of smoking were all significantly associated with liver cancer among men. Compared to HBsAg-negative never smokers, the adjusted ORs were 1.25 (95% CI: 1.03-1.52) for HBsAg-negative ever smokers, 7.66 (95% CI: 6.05-9.71) for HBsAg-positive never smokers, and 15.68 (95% CI: 12.06-20.39) for HBsAg-positive ever smokers. These different odds ratios indicated super-additive (RERI: 7.77, 95% CI: 3.81-11.73) and super-multiplicative interactions (ROR: 1.64, 95% CI: 1.17-2.30) between hepatitis B virus (HBV) infection and tobacco smoking. Most associations and interactions detected remained statistically significant after SB adjustments. Tobacco smoking and HBV infection positively interact in the development of liver cancer. PMID- 29193055 TI - Facial shape manifestations of growth faltering in Tanzanian children. AB - Variation in the shape of the human face and in stature is determined by complex interactions between genetic and environmental influences. One such environmental influence is malnourishment, which can result in growth faltering, usually diagnosed by means of comparing an individual's stature with a set of age appropriate standards. These standards for stature, however, are typically ascertained in groups where people are at low risk for growth faltering. Moreover, genetic differences among populations with respect to stature are well established, further complicating the generalizability of stature-based diagnostic tools. In a large sample of children aged 5-19 years, we obtained high resolution genomic data, anthropometric measures and 3D facial images from individuals within and around the city of Mwanza, Tanzania. With genome-wide complex trait analysis, we partitioned genetic and environmental variance for growth outcomes and facial shape. We found that children with growth faltering have faces that look like those of older and taller children, in a direction opposite to the expected allometric trajectory, and in ways predicted by the environmental portion of covariance at the community and individual levels. The environmental variance for facial shape varied subtly but significantly among communities, whereas genetic differences were minimal. These results reveal that facial shape preserves information about exposure to undernourishment, with important implications for refining assessments of nutritional status in children and the developmental-genetics of craniofacial variation alike. PMID- 29193056 TI - Identification of a novel fusion gene HMGA2-EGFR in glioblastoma. AB - Glioblastoma is one of the most malignant forms of cancer, for which no effective targeted therapy has been found. Although The Cancer Genome Atlas has provided a list of fusion genes in glioblastoma, their role in progression of glioblastoma remains largely unknown. To search for novel fusion genes, we obtained RNA-seq data from TGS-01 human glioma-initiating cells, and identified a novel fusion gene (HMGA2-EGFR), encoding a protein comprising the N-terminal region of the high-mobility group AT-hook protein 2 (HMGA2) fused to the C-terminal region of epidermal growth factor receptor (EGFR), which retained the transmembrane and kinase domains of the EGFR. This fusion gene product showed transforming potential and a high tumor-forming capacity in cell culture and in vivo. Mechanistically, HMGA2-EGFR constitutively induced a higher level of phosphorylated STAT5B than EGFRvIII, an in-frame exon deletion product of the EGFR gene that is commonly found in primary glioblastoma. Forced expression of HMGA2-EGFR enhanced orthotopic tumor formation of the U87MG human glioma cell line. Furthermore, the EGFR kinase inhibitor erlotinib blocked sphere formation of TGS-01 cells in culture and inhibited tumor formation in vivo. These findings suggest that, in addition to gene amplification and in-frame exon deletion, EGFR signaling can also be activated by gene fusion, suggesting a possible avenue for treatment of glioblastoma. PMID- 29193057 TI - Prognostic utility of six mutated genes for older patients with acute myeloid leukemia. AB - Approximately 50% of older patients with acute myeloid leukemia (AML) do not obtain chromosomal abnormalities as an effective risk-stratification, and present cytogenetically normal AML (CN-AML). To develop a reliable prediction model for stratifying the risk of these elderly patients, we conducted a study with a discovery and validation design. As a result, we found the top 6 mutated genes in the discovery cohort of 26 case by the whole exome sequencing, and verified as recurrent mutations in the large cohort of 329 patients by Sanger sequencing. The top 6 genes were NPM1, FLT3-ITD, DNMT3A, CEBPA double allele, IDH1 and IDH2 mutations, and the frequency of each gene in the combining cohort was 36.8%, 19.8%, 20.1%, 5.8%, 14.9% and 22.5%, respectively. In addition, clinical variables such as age, white blood cell counts, genes of IDH1 and DNMT3A mutations, European LeukemiaNet genotype (NPM1 mutations and lacking FLT3-ITD or CEBPA double allele mutations) and treatment protocols were independent factors for predicting the probabilities of overall and event-free survival. The prediction nomograms based on these significant factors showed accurate discrimination. In conclusion, we developed a reliable prediction model for stratifying the risk of elderly patients with CN-AML. PMID- 29193058 TI - Posttraumatic growth in a heterogeneous sample of traumatically injured patients 1 year postinjury. AB - OBJECTIVE: Posttraumatic growth (PTG) describes positive change resulting from challenging life events. The current study examined factors associated with PTG in traumatically injured patients 1 year postinjury. METHOD: Participants (N = 221) in this prospective cohort study included adults admitted to a Level I trauma center. Over half the participants (60%) were male, with a mean age of 47. Participants completed baseline measures during hospitalization. PTG was assessed at 12-month follow-up. RESULTS: Greater PTG was associated with minority race/ethnicity, lower income, automotive collision, and premorbid psychological disorder other than depression or posttraumatic stress (PTS). These variables are also known to predict PTS in trauma patients. Analysis confirmed that greater PTS at follow-up was associated with more growth. CONCLUSION: Participants with the most growth also experienced the most distress. This finding demonstrates the importance of implementing psychological screening and intervention for trauma patients in the acute care setting to reduce PTS and facilitate growth.

Although exercise has been used as an intervention for ameliorating cognitive deficits in various disorders, the effect on cognitive changes induced by nicotine exposure and its underlying mechanisms remain unclear. The purpose of this study was to investigate the effects of exercise on nicotine reward-associated cognitive behaviors in adolescent rats subjected to nicotine conditioned place preference paradigm (CPP). Male adolescent rats were trained on the Go/NoGo task, then subjected to nicotine CPP, and then randomly separated into four groups: sedentary (SED), high- (HE), moderate- (ME), and low-intensity (LE) exercise. Rats in exercise groups performed treadmill running 30 min daily for 10 days. Results showed that MEs had shorter escape latencies in the Morris water maze (MWM) test compared to SEDs. Although time spent and distance swam in the target quadrant significantly increased in both the MEs and HEs, the number of target quadrant crosses increased significantly only in MEs. MEs and HEs showed higher performance accuracy on NoGo and lower scores on CPP tasks. Expression of alpha7 nicotinic acetylcholine receptors (nAChRs) and downstream signaling molecules increased in MEs in prefrontal cortex but not hippocampus, with alpha7 nAChRs expression positively associated with NoGo accuracy and MWM probe test performance, but negatively correlated with CPP scores. The findings of this study suggest that moderate-intensity exercise can improve nicotine induced cognitive behaviors, and implicates prefrontal cortical alpha7 nAChR-mediated signal transduction as a possible mechanism.

AB - The properties of operant reinforcers are dynamic and dependent on a number of variables, such as schedule and effort. There has been sparse research on the generalized conditioned properties of token reinforcement. We evaluated leisure items, edible items, and tokens using a progressive ratio schedule with three children with diagnoses of ASD and developmental delays. The highest break points occurred during the token reinforcement condition for two out of three participants, but response rates tended to be higher with edibles. We then evaluated the effects of presession access to edibles on the break points of edible items and tokens with two participants. Break points decreased only in the edible reinforcement condition, and the participants chose to work for leisure items rather than edibles when presession access to edibles was in place. These findings suggest that the tokens functioned as generalized conditioned reinforcers. PMID- 29193061 TI - Modern Day Management of Headache Questions and Answers. PMID- 29193062 TI - The question-behaviour effect in intergroup attitudes research: When do attitudes towards a minority predict a relevant behaviour? AB - We hypothesised that the question-behaviour effect, referred to as the influence of questioning about a given behaviour on its subsequent performance, is a relevant issue when exploring the external validity of intergroup attitudes. In a pair of studies, we have corroborated that merely expressing attitudes towards the Jewish minority affects people's relevant behaviour towards this group. In an Internet study, participants who first completed verbal attitude measures were more likely to donate to a Jewish organisation compared to those who completed the measures after making the decision to donate. Moreover, responses to attitude measures of various types and donating to the Jewish organisation were correlated when attitudes had been expressed in the first step. When attitudes were measured after the decision to donate, only the responses to the traditional anti-Semitic scale were correlated with this behaviour. In the field study, in which the time interval between attitude and behaviour measures was introduced, no question behaviour effect was observed. We explain the results with reference to cognitive dissonance and attitude accessibility mechanisms and discuss them in a broader context of attitude-behaviour research. PMID- 29193063 TI - Clinical and Autopsy Characteristics of Fatal Methamphetamine Toxicity in Australia. AB - Characteristics of death attributed solely to methamphetamine toxicity (MT, n = 93) by forensic pathologists were examined and compared to cases of multiple drug toxicity (MDT, n = 634). The mean age of MT cases was 36.7 years, and 86.0% were male. Strenuous activity was reported in 12.9%. The most common witness observations were: collapse (60.3%), difficulty in breathing (36.2%), and hyperthermia (27.6%). MT cases had higher blood methamphetamine (0.54 vs. 0.11 mg/L) and amphetamine (0.04 vs. 0.02 mg/L) concentrations and lower likelihoods for opioids (12.5% vs. 80.9%), hypnosedatives (27.3 vs. 60.7%), antidepressants (14.8 vs. 29.8%), and antipsychotics (9.1 vs. 19.7%). MT cases had significantly heavier hearts than MDT cases (423.4 vs. 385.8 g) and were more likely to have cardiomegaly (37.1 vs. 20.4%) and replacement fibrosis (25.7 vs. 14.5%). The clinical picture was of a sudden cardiac event in a middle-aged man with a high methamphetamine concentration. Cardiovascular signs of heavy methamphetamine use are frequently seen. PMID- 29193064 TI - A Morphometric Outline Analysis of Ancestry and Sex Differences in Cranial Shape. AB - Forensic anthropological techniques that utilize nonmetric cranial traits to estimate sex and ancestry have historically been criticized for their subjectivity and qualitative nature. Nonmetric traits, however, continue to be valuable tools in identifying remains in forensic investigations. In this study, geometric morphometric analyses of cranial outlines were performed to quantitatively assess population and sex variation in modern human cranial shapes and to verify group differences in previously reported qualitative traits. Elliptical Fourier analysis was conducted on two-dimensional images of the left lateral, posterior, and superior cranial views from 198 U.S. Black and White crania. Results reveal significant sex and population differences in cranial shape that generally coincide with traditional qualitative descriptions. Although sex classification was relatively low (70.2%), ancestry classification was higher (92.4%), indicating that outline analyses that incorporate multiple nonmetric traits into a single statistical analysis may provide a more objective and accurate means of ancestry classification. PMID- 29193065 TI - Stereological assessment of the blood-air barrier and the surfactant system after mesenchymal stem cell pretreatment in a porcine non-heart-beating donor model for lung transplantation. AB - More frequent utilization of non-heart-beating donor (NHBD) organs for lung transplantation has the potential to relieve the shortage of donor organs. In particular with respect to uncontrolled NHBD, concerns exist regarding the risk of ischaemia/reperfusion (IR) injury-related graft damage or dysfunction. Due to their immunomodulating and tissue-remodelling properties, bone-marrow-derived mesenchymal stem cells (MSCs) have been suspected of playing a beneficial role regarding short- and long-term survival and function of the allograft. Thus, MSC administration might represent a promising pretreatment strategy for NHBD organs. To study the initial effects of warm ischaemia and MSC application, a large animal lung transplantation model was generated, and the structural organ composition of the transplanted lungs was analysed stereologically with particular respect to the blood-gas barrier and the surfactant system. In this study, porcine lungs (n = 5/group) were analysed. Group 1 was the sham-operated control group. In pigs of groups 2-4, cardiac arrest was induced, followed by a period of 3 h of ventilated ischaemia at room temperature. In groups 3 and 4, 50 * 106 MSCs were administered intravascularly via the pulmonary artery and endobronchially, respectively, during the last 10 min of ischaemia. The left lungs were transplanted, followed by a reperfusion period of 4 h. Then, lungs were perfusion-fixed and processed for light and electron microscopy. Samples were analysed stereologically for IR injury-related structural parameters, including volume densities and absolute volumes of parenchyma components, alveolar septum components, intra-alveolar oedema, and the intracellular and intra-alveolar surfactant pool. Additionally, the volume-weighted mean volume of lamellar bodies (lbs) and their profile size distribution were determined. Three hours of ventilated warm ischaemia was tolerated without eliciting histological or ultrastructural signs of IR injury, as revealed by qualitative and quantitative assessment. However, warm ischaemia influenced the surfactant system. The volume-weighted mean volume of lbs was reduced significantly (P = 0.024) in groups subjected to ischaemia (group medians of groups 2-4: 0.180-0.373 MUm3) compared with the sham control group (median 0.814 MUm3). This was due to a lower number of large lb profiles (size classes 5-15). In contrast, the intra alveolar surfactant system was not altered significantly. No significant differences were encountered comparing ischaemia alone (group 2) or ischaemia plus application of MSCs (groups 3 and 4) in this short-term model. PMID- 29193066 TI - Broader head, stronger bite: In vivo bite forces in European eel Anguilla anguilla. AB - This work examined three different phenotypes of the yellow-eel stage of the European eel Anguilla anguilla, broad-heads, narrow-heads and eels with an intermediate head shape. The aim was to see whether broad-headed A. anguilla, which generally consume harder, larger prey, such as crustaceans and fish, exerted greater bite force than the narrow-headed variant, which mainly consume soft, small prey such as chironomid larvae. It was found that in 99 yellow A. anguilla, in vivo bite force of broad-heads are higher compared with narrow-heads and intermediates. PMID- 29193067 TI - The role of S-nitrosylation of kainate-type of ionotropic glutamate receptor 2 in epilepsy induced by kainic acid. AB - Epilepsy is a chronic brain disease affecting millions of individuals. Kainate receptors, especially kainate-type of ionotropic glutamate receptor 2 (GluK2), play an important role in epileptogenesis. Recent data showed that GluK2 could undergo post-translational modifications in terms of S-nitrosylation (SNO), and affect the signaling pathway of cell death in cerebral ischemia-reperfusion. However, it is unclear whether S-nitrosylation of GluK2 (SNO-GluK2) contributes to cell death induced by epilepsy. Here, we report that kainic acid-induced SNO GluK2 is mediated by GluK2 itself, regulated by neuronal nitric oxide synthase (nNOS) and the level of cytoplasmic calcium in vivo and in vitro hippocampus neurons. The whole-cell patch clamp recordings showed the influence of SNO-GluK2 on ion channel characterization of GluK2-Kainate receptors. Moreover, immunohistochemistry staining results showed that inhibition of SNO-GluK2 by blocking nNOS or GluK2 or by reducing the level of cytoplasmic calcium-protected hippocampal neurons from kainic acid-induced injury. Finally, immunoprecipitation and western blotting data revealed the involvement of assembly of a GluK2-PSD95 nNOS signaling complex in epilepsy. Taken together, our results showed that the SNO-GluK2 plays an important role in neuronal injury of epileptic rats by forming GluK2-PSD95-nNOS signaling module in a cytoplasmic calcium-dependent way, suggesting a potential therapeutic target site for epilepsy. PMID- 29193068 TI - Advanced glycation end-products increase IL-6 and ICAM-1 expression via RAGE, MAPK and NF-kappaB pathways in human gingival fibroblasts. AB - BACKGROUND AND OBJECTIVES: Diabetes mellitus (DM) is a risk factor for periodontal diseases and may exacerbate the progression of the pathogenesis of periodontitis. Advanced glycation end-products (AGEs) cause DM complications relative to levels of glycemic control and larger amounts accumulate in the periodontal tissues of patients with periodontitis and DM. In the present study, we investigated the effects of AGEs on the expression of inflammation-related factors in human gingival fibroblasts (HGFs) to elucidate the impact of AGEs on DM-associated periodontitis. MATERIAL AND METHODS: HGFs were cultured with or without AGEs. Cell viability was examined, and RNA and protein fractions were isolated from AGE-treated cells. The expression of interleukin (IL)-6, intercellular adhesion molecule-1 (ICAM-1), and the receptor for AGE (RAGE) was investigated using reverse transcription-polymerase chain reaction, quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay, and reactive oxygen species activity was measured using a kit with 2',7' dichlorofluorescin diacetate. Human monocytic cells (THP-1) labeled with a fluorescent reagent were co-cultured with HGFs treated with AGEs and IL-6 siRNA, and the adhesive activity of THP-1 cells to HGFs was assessed. The expression of IL-6 and ICAM-1 was examined when HGFs were pretreated with recombinant human IL 6, the siRNAs of RAGE and IL-6, and inhibitors of MAPK and NF-kappaB, and then cultured with and without AGEs. The phosphorylation of MAPK and NF-kappaB was assessed using western blotting. RESULTS: AGEs increased the mRNA and protein expressions of RAGE, IL-6, ICAM-1 and reactive oxygen species activity in HGFs, and promoted the adhesion of THP-1 cells to HGFs, but had no effect on cell viability until 72 hours. Recombinant human IL-6 increased ICAM-1 expression in HGFs, while the siRNAs of RAGE and IL-6 inhibited AGE-induced IL6 and ICAM1 mRNA expression, and IL-6 siRNA depressed AGE-induced THP-1 cell adhesion. AGEs increased the phosphorylation of p38 and ERK MAPKs, p65 NF-kappaB and IkappaBalpha, while inhibitors of p38, ERK MAPKs and NF-kappaB significantly decreased AGE-induced IL-6 and ICAM-1 expression. CONCLUSION: AGEs increase IL-6 and ICAM-1 expression via the RAGE, MAPK and NF-kappaB pathways in HGFs and may exacerbate the progression of the pathogenesis of periodontal diseases. PMID- 29193069 TI - The Flexitarian FlipTM : Testing the Modalities of Flavor as Sensory Strategies to Accomplish the Shift from Meat-Centered to Vegetable-Forward Mixed Dishes. AB - : The American diet is lacking in plant-based foods and vegetables, higher in protein than necessary, and too centered on meat and poultry. Two major dietary shifts recommended by the 2015-2020 U.S. Dietary Guidelines are to increase vegetable intake and to increase the variety of protein food sources. One suggested strategy for doing this is to partially replace meat and poultry with vegetables and plant-based ingredients in mixed dishes. This research tested the potential of flavor modalities (taste, aroma, trigeminal, and their combination) as strategies to increase the sensory appeal of plant-forward dishes. Consumer testing (n = 141) was conducted in a cross-sectional design in a laboratory setting on 24 recipe variations. Three factors were tested: cuisine (Latin American, Mediterranean, and Asian), meat proportion (high-meat/low-vegetable versus low-meat/high-vegetable), and flavor strategy (taste, aroma, trigeminal, and a reduced-intensity trimodal combination). Statistical analysis was performed in R and XLSTAT-Sensory(r) 2017. Four consumer preference segments were uncovered. The low-meat dishes achieved parity or higher in consumer acceptance across all recipes and flavor strategies. The taste and trigeminal strategies both had higher overall acceptability scores than the aroma strategy, and the differences were significant (P < 0.05) in some consumer preference segments. The consumers successfully characterized the samples using a Check-All-That-Apply task, verifying the flavor strategy design. This research provides insight into consumer preferences regarding flavor strategies to partially replace meat with vegetables in mixed dishes. The trigeminal and trimodal combination strategies were found to be the most promising flavor modalities to use to implement this shift. PRACTICAL APPLICATION: There is little knowledge of American consumer preferences regarding vegetables in mixed dishes. Mixed dishes are a strategy recommended by the U.S. Dietary Guidelines to increase vegetable consumption and variety of protein sources. This research explores various flavor and culinary strategies with which to carry out the mixed dish meat-vegetable swap and to test the potential of the Flexitarian FlipTM (the shift from meat-centric to plant centric diets). This research shows that individuals have different preferences regarding the type of flavor they prefer in mixed dishes (for example, some consumers prefer salty and some prefer spicy), so if the dietitian can recommend recipes that cater to that client's food and flavor preferences, the client will be more likely to adhere to their diet. PMID- 29193070 TI - Development of the human shoulder joint during the embryonic and early fetal stages: anatomical considerations for clinical practice. AB - Although several studies have been published regarding the morphology and anatomical variations of the human shoulder joint, most have dealt with adult individuals. Those looking into the development of the joint have been focused on specific structures or have observed specimens in advanced gestational stages. The goal of this paper is to perform a complete analysis of the embryonic and early fetal development of the elements in the shoulder joint, and to clarify some contradictory data in the literature. In our study, serial sections of 32 human embryos (Carnegie stages 16-23) and 26 fetuses (9-13 weeks) were analyzed. The chondrogenic anlagen of the humerus and the medial border of the scapula can be observed from as early as Carnegie stage 17, whereas that of the rest of the scapula appears at stage 18. The osteogenic process begins in week 10 for the humeral head and week 11 for the scapula. At stage 19 the interzone becomes apparent, which will form the glenohumeral joint. In the next stage the glenohumeral joint will begin delaminating and exhibiting a looser central band. Denser lateral bands will join the humeral head (caput humeri) and the margins of the articular surface of the scapula, thus forming the glenoid labrum, which can be fully appreciated by stage 22. In 24-mm embryos (stage 21) we can observe, for the first time, the long head of the biceps tendon (which is already inserted in the glenoid labrum by week 9), and the intertubercular sulcus, whose depth is apparent since week 12. Regarding ligamentous structures, the coracohumeral ligament is observed at the end of Carnegie stage 23, whereas the primitive glenohumeral ligament already appeared in week 10. The results of this study provide a detailed description of the morphogenesis, origin and chronological order of appearance of the main intrinsic structures of the human shoulder joint during late embryonic and early fetal development. We expect these results to help explain several functional aspects of the shoulder joint, and to clarify some contradictory data in the literature regarding this complex anatomical and biomechanical structure, helping future researchers in their efforts.

AB - This study compared the critical swimming speed (Ucrit ) and endurance performance of three Australian freshwater fish species in different swim-test apparatus. Estimates of Ucrit measured in a large recirculating flume were greater for all species compared with estimates from a smaller model of the same recirculating flume. Large differences were also observed for estimates of endurance swimming performance between these recirculating flumes and a free surface swim tunnel. Differences in estimates of performance may be attributable to variation in flow conditions within different types of swim chambers. Variation in estimates of swimming performance between different types of flumes complicates the application of laboratory-based measures to the design of fish passage infrastructure.

AB - Rates of syphilis are beginning to once again increase, with the World Health Organization estimating that in recent years there were 12 million new cases of syphilis each year; in 2002, syphilis was responsible for 0.3% of deaths globally. At-risk groups include young males (20-29 years), prisoners, and sex workers. Increased rates in young females have elevated the numbers of congenital cases. Review of the University of Adelaide Pathology Archive revealed four cases with significant pathology, which included cardiac gummas and aortic arch aneurysms. These cases demonstrate the cardiovascular characteristics of untreated syphilis in the tertiary stage. Cases with such advanced pathology will only occur where diagnoses have not been made, and/or standard antibiotic therapy has not been implemented in the early stage of disease. PMID- 29193073 TI - Carbon and Nitrogen Stable Isotope Analyses of Ephedra Plant and Ephedrine Samples and Their Application For Methamphetamine Profiling. AB - In this study, stable isotope ratio analysis was used to track the precursor information of methamphetamine. The delta13 C and delta15 N values of 30 nature ephedra plants, 12 synthetic ephedrine/pseudoephedrine (ephedrine), 14 natural ephedrine, and 987 seized methamphetamine samples were measured and compared. Due to different weather and earth conditions, the delta13 C and delta15 N values of ephedra plants grown in the east and the west of Inner Mongolia showed great difference. The delta15 N values of ephedra plants were consistent with related ephedrine extracted from them. Moreover, the criteria to infer the synthetic origin of ephedrine were set up after the analysis of natural and synthetic ephedrine samples. Finally, the precursor origins of 949 seized methamphetamine samples synthesized by Emde and Nagai method were tentatively inferred. Influenced by different preprecursors, the delta13 C values of seized methamphetamine samples that synthesized from P2P also showed great difference, and this result is consistent with the reported data. PMID- 29193074 TI - Effects of 1alpha,25 Dihydroxyvitamin D3 on Pro-inflammatory Cytokines of Palmitic Acid Treated Thp-1 Cells. AB - : The level of saturated fatty acids, such as palmitic acid (PA), correlates with chronic inflammation in obese and metabolic syndrome patients. However, low level of vitamin D3 is observed in those conditions. The aim of this study is to investigate effects of 1alpha,25(OH)2 D3 on PA-treated THP-1 cells. Using quantitative real-time polymerase chain reaction, we measure mRNA expression of pro-inflammatory cytokines: TNF-alpha, Interleukin (IL)-1beta, IL-6, and chemokine IL-8 under PA and 1alpha,25(OH)2 D3 influence. PA, at all concentrations (25-100 MUM), enhanced LPS stimulatory effect on those mRNA expression compared to LPS-treated and -untreated cells. Combination with 1alpha,25(OH)2 D3 increased cytokine expression at high (10-6 M) and high-normal (10-8 M) concentrations compared to PA + LPS and LPS alone, both for 2 and 24 h. However, low-normal (10-10 M) and low (10-12 M) levels of 1alpha,25(OH)2 D3 could not enhance PA effect, but mRNA expression of pro-inflammatory cytokine was higher than LPS-treated cells. Upstream pathway of 1alpha,25(OH)2 D3 , which is cholecalciferol, also gave the similar result. Further, inhibition of calcium pathway does not play a role in this mechanism. Thus, these findings support pro inflammatory effect of PA and vitamin D3 on innate immune response, especially on fat-induced inflammation. PRACTICAL APPLICATION: The effect of vitamin D3 on chronic inflammation in obesity is uncertain. This study shows an in vitro possibility that vitamin D3 could exaggerate inflammation when combined with high SFAs. The idea of using vitamin D3 supplement to modulate inflammation in fat related inflammation needs further refined experiments before its clinical application. PMID- 29193075 TI - Introducing 3D Printed Models as Demonstrative Evidence at Criminal Trials. AB - This case report presents one of the first reported uses of a 3D printed exhibit in an English homicide trial, in which two defendants were accused of beating their victim to death. The investigation of this crime included a micro-CT scan of the victim's skull, which assisted the pathologist to determine the circumstances of the assault, in particular regarding the number of assault weapons and perpetrators. The scan showed two distinct injury shapes, suggesting the use of either two weapons or a single weapon with geometrically distinct surfaces. It subsequently served as the basis for a 3D print, which was shown in court in one of the first examples that 3D printed physical models have been introduced as evidence in a criminal trial in the United Kingdom. This paper presents the decision-making process of whether to use 3D printed evidence or not. PMID- 29193076 TI - Resurgent sodium current promotes action potential firing in the avian auditory brainstem. AB - KEY POINTS: Auditory brainstem neurons of all vertebrates fire phase-locked action potentials (APs) at high rates with remarkable fidelity, a process controlled by specialized anatomical and biophysical properties. This is especially true in the avian nucleus magnocellularis (NM) - the analogue of the mammalian anteroventral cochlear nucleus. In addition to high voltage-activated potassium (KHVA ) channels, we report, using whole cell physiology and modelling, that resurgent sodium current (INaR ) of sodium channels (NaV ) is equally important and operates synergistically with KHVA channels to enable rapid AP firing in NM. Anatomically, we detected strong NaV 1.6 expression near hearing maturation, which was less distinct during hearing development despite functional evidence of INaR , suggesting that multiple NaV channel subtypes may contribute to INaR . We conclude that INaR plays an important role in regulating rapid AP firing for NM neurons, a property that may be evolutionarily conserved for functions related to similar avian and mammalian hearing. ABSTRACT: Auditory brainstem neurons are functionally primed to fire action potentials (APs) at markedly high rates in order to rapidly encode the acoustic information of sound. This specialization is critical for survival and the comprehension of behaviourally relevant communication functions, including sound localization and distinguishing speech from noise. Here, we investigated underlying ion channel mechanisms essential for high-rate AP firing in neurons of the chicken nucleus magnocellularis (NM) - the avian analogue of bushy cells of the mammalian anteroventral cochlear nucleus. In addition to the established function of high voltage-activated potassium channels, we found that resurgent sodium current (INaR ) plays a role in regulating rapid firing activity of late-developing (embryonic (E) days 19-21) NM neurons. INaR of late-developing NM neurons showed similar properties to mammalian neurons in that its unique mechanism of an 'open channel block state' facilitated the recovery and increased the availability of sodium (NaV ) channels after depolarization. Using a computational model of NM neurons, we demonstrated that removal of INaR reduced high-rate AP firing. We found weak INaR during a prehearing period (E11-12), which transformed to resemble late-developing INaR properties around hearing onset (E14-16). Anatomically, we detected strong NaV 1.6 expression near maturation, which became increasingly less distinct at hearing onset and prehearing periods, suggesting that multiple NaV channel subtypes may contribute to INaR during development. We conclude that INaR plays an important role in regulating rapid AP firing for NM neurons, a property that may be evolutionarily conserved for functions related to similar avian and mammalian hearing. PMID- 29193077 TI - Evaluating bioequivalence of meloxicam tablets: is in-vitro dissolution test overdiscriminating? AB - OBJECTIVES: The aim of the study was to assess the impact of the differences in dissolution profiles of meloxicam tablets on the in-vivo bioavailability parameters after oral administration. METHODS: Compare in-vitro dissolution testing in the recommended media to evaluate in-vivo bioequivalence outcomes for the Biopharmaceutics Classification System Class II weak acidic drugs. Nine Beagle dogs received a single oral administration of each formulation (7.5 mg) in a three-way crossover design. KEY FINDINGS: The dissolution of meloxicam from both test products showed marked differences with that from the reference tablet in pH 1.0, 4.5 and 6.8 media at 50 or 75 rpm. Both formulations exhibiting slow or fast dissolution were then compared with the reference product for in-vivo bioequivalence study. Both products were bioequivalent with the reference tablet in either extent or rate of oral absorption. It indicated that the dissolution profiles which discriminated between the formulations in vitro did not accurately predict the in-vivo bioequivalence outcomes. CONCLUSIONS: Comparative dissolution profiles using similarity factor (f2 ) in the recommended media should be relaxed to fulfil the requirements for the development, scale-up and postapproval changes to immediate release oral solid dosage forms of meloxicam.

AB - The Ohio Attorney General's Sexual Assault Kit (SAK) Testing Initiative has resulted in nearly 14,000 kits being processed since the initiation of the project in 2012. A logistic regression model was fit to the data from 2500 SAKs in order to determine the probability of obtaining at least one Combined DNA Index System (CODIS) eligible DNA profile based on a number of predictor variables. The probability of obtaining at least one CODIS eligible DNA profile from an SAK varied as a function of (i) days to kit collection following a sexual assault; (ii) years to kit submission to the laboratory for testing following kit collection; (iii) the age of the victim; and (iv) the occurrence of victim reported consensual sex around the time of the assault and/or kit collection. These findings demonstrate the utility of the statistical modeling of data obtained from the "forklift" testing approach of sexual assault kits. PMID- 29193078 TI - Termination of re-entrant atrial tachycardia via optogenetic stimulation with optimized spatial targeting: insights from computational models. AB - KEY POINTS: Optogenetics has emerged as a potential alternative to electrotherapy for treating heart rhythm disorders, but its applicability for terminating atrial arrhythmias remains largely unexplored. We used computational models reconstructed from clinical MRI scans of fibrotic patient atria to explore the feasibility of optogenetic termination of atrial tachycardia (AT), comparing two different illumination strategies: distributed vs. targeted. We show that targeted optogenetic stimulation based on automated, non-invasive flow-network analysis of patient-specific re-entry morphology may be a reliable approach for identifying the optimal illumination target in each individual (i.e. the critical AT isthmus). The above-described approach yields very high success rates (up to 100%) and requires dramatically less input power than distributed illumination We conclude that simulations in patient-specific models show that targeted light pulses lasting longer than the AT cycle length can efficiently and reliably terminate AT if the human atria can be successfully light-sensitized via gene delivery of ChR2. ABSTRACT: Optogenetics has emerged as a potential alternative to electrotherapy for treating arrhythmia, but feasibility studies have been limited to ventricular defibrillation via epicardial light application. Here, we assess the efficacy of optogenetic atrial tachycardia (AT) termination in human hearts using a strategy that targets for illumination specific regions identified in an automated manner. In three patient-specific models reconstructed from late gadolinium-enhanced MRI scans, we simulated channelrhodopsin-2 (ChR2) expression via gene delivery. In all three models, we attempted to terminate re-entrant AT (induced via rapid pacing) via optogenetic stimulation. We compared two strategies: (1) distributed illumination of the endocardium by multi-optrode grids (number of optrodes, Nopt = 64, 128, 256) and (2) targeted illumination of the critical isthmus, which was identified via analysis of simulated activation patterns using an algorithm based on flow networks. The illuminated area and input power were smaller for the targeted approach (19-57.8 mm2 ; 0.6-1.8 W) compared to the sparsest distributed arrays (Nopt = 64; 124.9 +/- 6.3 mm2 ; 3.9 +/- 0.2 W). AT termination rates for distributed illumination were low, ranging from <5% for short pulses (1/10 ms long) to ~20% for longer stimuli (100/1000 ms). When we attempted to terminate the same AT episodes with targeted illumination, outcomes were similar for short pulses (1/10 ms long: 0% success) but improved for longer stimuli (100 ms: 54% success; 1000 ms: 90% success). We conclude that simulations in patient-specific models show that light pulses lasting longer than the AT cycle length can efficiently and reliably terminate AT in atria light-sensitized via gene delivery. We show that targeted optogenetic stimulation based on analysis of AT morphology may be a reliable approach for defibrillation and requires less power than distributed illumination. PMID- 29193080 TI - The non-peptidic delta-opioid receptor agonist Tan-67 mediates neuroprotection post-ischemically and is associated with altered amyloid precursor protein expression, maturation and processing in mice. AB - Tan-67 is a selective non-peptidic delta-opioid receptor (DOR) agonist that confers neuroprotection against cerebral ischemia/reperfusion (I/R)-caused neuronal injury in pre-treated animals. In this study, we examined whether post ischemic administration of Tan-67 in stroke mice is also neuroprotective and whether the treatment affects expression, maturation and processing of the amyloid precursor protein (APP). A focal cerebral I/R model in mice was induced by middle cerebral artery occlusion for 1 h and Tan-67 (1.5, 3 or 4.5 mg/kg) was administered via the tail vein at 1 h after reperfusion. Alternatively, naltrindole, a selective DOR antagonist (5 mg/kg), was administered 1 h before Tan-67 treatment. Our results showed that post-ischemic administration of Tan-67 (3 mg/kg or 4.5 mg/kg) was neuroprotective as shown by decreased infarct volume and neuronal loss following I/R. Importantly, Tan-67 improved animal survival and neurobehavioral outcomes. Conversely, naltrindole abolished Tan-67 neuroprotection in infarct volume. Tan-67 treatment also increased APP expression, maturation and processing in the ipsilateral penumbral area at 6 h but decreased APP expression and maturation in the same brain area at 24 h after I/R. Tan-67-induced increase in APP expression was also seen in the ischemic cortex at 24 h following I/R. Moreover, Tan-67 attenuated BACE-1 expression, beta secretase activity and the BACE cleavage of APP in the ischemic cortex at 24 h after I/R, which was abolished by naltrindole. Our data suggest that Tan-67 is a promising DOR-dependent therapeutic agent for treating I/R-caused disorder and that Tan-67-mediated neuroprotection may be mediated via modulating APP expression, maturation and processing, despite an uncertain causative relationship between the altered APP and the outcomes observed.

In this article, we will summarize the most recent literature on natural history and recurrence patterns of RPS compiled from multi-institutional collaborative studies and centers with extended follow-up data, and based on this evidence, propose principles for histology-based post-operative surveillance protocols. PMID- 29193082 TI - A preliminary investigation of the effect of sample collection technique on the cell and RNA content of fine-needle aspirates of five canine tumours. AB - OBJECTIVES: To evaluate the effect of syringe size, needle size, number of needle passes and operator experience on cell yield from tumour fine-needle aspirates, and the quantity and quality of extractable RNA. MATERIALS AND METHODS: Fine needle aspirates were collected from canine lymphoma, cutaneous mast cell tumour, anal gland adenocarcinoma, fibrosarcoma and oral malignant melanoma using nine different techniques. RESULTS: There was a significant difference in cell yield between fine-needle aspirate techniques for melanoma, lymphoma and anal gland adenocarcinoma. The application of suction yielded the largest number of cells. Cell numbers in lymphoma and fibrosarcoma aspirates collected by different veterinary surgeons were not significantly different. Use of a smaller gauge needle and suction increased the quantity of RNA isolated from fibrosarcoma and anal gland adenocarcinoma aspirates, but did not influence RNA integrity. CLINICAL SIGNIFICANCE: Suction during fine-needle aspiration increases cell numbers obtained from five common canine tumours. Suction increases the quantity of RNA isolated from anal gland adenocarcinoma and fibrosarcoma aspirates without affecting RNA quality. Junior veterinary surgeons gain comparable cell numbers to senior staff.

PMID- 29193083 TI - Integrating expression-related SNPs into genome-wide gene- and pathway-based analyses identified novel lung cancer susceptibility genes. AB - Traditional pathway analysis map single nucleotide polymorphisms (SNPs) to genes according to physical position, which lacks sufficient biological bases. Here, we incorporated genetics of gene expression into gene- and pathway-based analysis to identify genes and pathways associated with lung cancer risk. We identified expression-related SNPs (eSNPs) in lung tissues and integrated these eSNPs into three lung cancer genome-wide association studies (GWASs), including 12,843 lung cancer cases and 12,639 controls. We used SKAT-C for gene-based analysis, and conditional analysis to identify independent eSNPs of each gene. ARTP algorithm was used for pathway analysis. A total of 374,382 eSNPs in the GWAS datasets survived quality control, which were mapped to 5,084 genes and 2,752 pathways. In the gene-based analysis, nine genes showed significant associations with lung cancer risk. Among them, TP63 (3q28), RP11-650L12.2 (15q25.1) and CHRNA5 (15q25.1) were located in known lung cancer susceptibility loci. We also validated two newly identified susceptibility loci (RNASET2 and AL133458.1 in 6q27, and MPZL3 in 11q23.3). Besides, DVL3 (3q27.1), RP11-522I20.3 (9q21.32) and CCDC116 (22q11.21) were identified as novel lung cancer susceptibility genes. Pathway analysis showed that pathways involved in protein structure, the Notch signaling pathway and the nicotinic acetylcholine receptor-related pathways were associated with lung cancer risk. Combing eSNPs, gene- and pathway-based analysis identifies novel lung cancer susceptibility genes, which serves as a powerful approach to decipher biological mechanisms underlying GWAS findings. PMID- 29193085 TI - Elevated brain natriuretic peptide (BNP) is an early marker for patients at risk for complications after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS + HIPEC). AB - BACKGROUND: Elevated BNP is associated with adverse cardiac outcomes after noncardiac surgery. We assessed BNP values as markers of perioperative fluid status and their correlation with major/cardiopulmonary (CP) complications following CRS + HIPEC. METHODS: Fluid balance, BNP levels, and morbidity data were collected for all patients undergoing CRS + HIPEC between 6/2014 and 2/2016. RESULTS: One hundred and twenty-nine patients underwent CRS + HIPEC for appendiceal adenocarcinoma (n = 99), mesothelioma (n = 16), and colon cancer (n = 14). Less than 10% had CP comorbidities. The median PCI was 14 (range 4-39); 89% underwent CC0/1 resection (n = 115). Median blood loss (EBL) was 497 mL (50 2700). Major complications (Clavien III-V) occurred in 16 (12%), CP in 17 (13%), and major/CP in 24 (18%). Thirty-day mortality occurred in 2 (1.5%). Elevated BNP on POD1 correlated with increased risk of major/CP complications (OR 2.2, P = 0.052). This was most pronounced in the 25 patients receiving cisplatin: for each 100 unit increase in POD1 BNP the OR for major/CP complication was 7.4 versus 1.2 for the remaining patients, P = 0.083. Multivariate analysis identified increased EBL (OR 4.1 P = 0.011) and a trend toward increased BNP on POD1 (OR for each 100 unit increase 2.0, P = 0.10) as risk factors for major/CP complications. CONCLUSIONS: Postoperative BNP measurement after CRS + HIPEC may guide postoperative fluid resuscitation and facilitate identification of patients at risk for major and/or cardiopulmonary complications.

PMID- 29193086 TI - Transfer rates of aflatoxins from herbal medicines to decoctions determined by an optimized high-performance liquid chromatography with fluorescence detection method. AB - OBJECTIVES: This study aimed to explore the transfer rates of aflatoxins from several contaminated herbal medicines by fungi to their decoctions. METHODS: Five types of commonly used herbal medicines including Lilii Bulbus, Hordei Fructus Germinatus, Nelumbinis Semen, Polygalae Radix and Bombyx Batryticatus were selected as the examples. Raw herbal medicine samples were treated by ultrasonication-assisted extraction with 70% methanol and immunoaffinity column clean-up, and the decoctions were prepared following the commonly used boiling method with water for 2 h. Then, the optimized high-performance liquid chromatography with fluorescence detection (HPLC-FLD) method was validated for the quantitative analysis of four aflatoxins (AFG2 , AFG1 , AFB2 and AFB1 ) after postcolumn photochemical derivatization, which was proved to be reliable and sensitive. KEY FINDINGS: Aflatoxins were detected to be transferred from the herbal medicines to decoctions with significantly different transfer rates in the five types of herbal medicines. Quietly high transfer rates of 7.26-115.36% for AFG2 , 4.37-26.37% for AFB1 and 9.64-47.68% for AFB2 were obtained. AFB1 as the most toxic aflatoxin expressed the lowest transfer rate, but still exhibited high amount in the samples. CONCLUSIONS: Therefore, the monitoring of aflatoxins in herbal medicines and their decoctions is in great urgency to ensure the security of consumers taking decoctions. PMID- 29193090 TI - Physiological stress responses to natural variation in predation risk: evidence from white sharks and seals. AB - Predators can impact ecosystems through consumptive or risk effects on prey. Physiologically, risk effects can be mediated by energetic mechanisms or stress responses. The predation-stress hypothesis predicts that risk induces stress in prey, which can affect survival and reproduction. However, empirical support for this hypothesis is both mixed and limited, and the conditions that cause predation risk to induce stress responses in some cases, but not others, remain unclear. Unusually clear-cut variation in exposure of Cape fur seals (Arctocephalus pusillus pusillus) to predation risk from white sharks (Carcharodon carcharias) in the waters of Southwestern Africa provides an opportunity to test the predation-stress hypothesis in the wild. Here, we measured fecal glucocorticoid concentrations (fGCM) from Cape fur seals at six discrete islands colonies exposed to spatiotemporal variation in predation risk from white sharks over a period of three years. We found highly elevated fGCM concentrations in seals at colonies exposed to high levels of unpredictable and relatively uncontrollable risk of shark attack, but not at colonies where seals were either not exposed to shark predation or could proactively mitigate their risk through antipredatory behavior. Differences in measured fGCM levels were consistent with patterns of risk at the site and seasonal level, for both seal adults and juveniles. Seal fGCM levels were not correlated with colony population size, density, and geographic location. Investigation at a high risk site (False Bay) also revealed strong correlations between fGCM levels and temporal variation in shark attack rates, but not with shark relative abundance. Our results suggest that predation risk will induce a stress response when risk cannot be predicted and/or proactively mitigated by behavioral responses.

AB - Patients with retroperitoneal sarcoma can present to a variety of clinicians with non-specific symptoms and retroperitoneal sarcomas can be incidental findings. Failure to recognize retroperitoneal sarcomas on imaging can lead to inappropriate management in non-specialist centers. Therefore it is critical that the possibility of retroperitoneal sarcoma should be considered with prompt referral to a soft tissue sarcoma unit. This review guides clinicians through a diagnostic pathway, introduces concepts in response assessment and new imaging developments. PMID- 29193093 TI - Molecular adaptations of adipose tissue to 6 weeks of morning fasting vs. daily breakfast consumption in lean and obese adults. AB - KEY POINTS: In lean individuals, 6 weeks of extended morning fasting increases the expression of genes involved in lipid turnover (ACADM) and insulin signalling (IRS2) in subcutaneous abdominal adipose tissue. In obese individuals, 6 weeks of extended morning fasting increases IRS2 expression in subcutaneous abdominal adipose tissue. The content and activation status of key proteins involved in insulin signalling and glucose transport (GLUT4, Akt1 and Akt2) were unaffected by extended morning fasting. Therefore, any observations of altered adipose tissue insulin sensitivity with extended morning fasting do not necessarily require changes in insulin signalling proximal to Akt. Insulin-stimulated adipose tissue glucose uptake rates are lower in obese versus lean individuals, but this difference is abolished when values are normalised to whole-body fat mass. This suggests a novel hypothesis which proposes that the reduced adipose glucose uptake in obesity is a physiological down-regulation to prevent excessive de novo lipogenesis. ABSTRACT: This study assessed molecular responses of human subcutaneous abdominal adipose tissue (SCAT) to 6 weeks of morning fasting. Forty nine healthy lean (n = 29) and obese (n = 20) adults provided SCAT biopsies before and after 6 weeks of morning fasting (FAST; 0 kcal until 12.00 h) or daily breakfast consumption (BFAST; >=700 kcal before 11.00 h). Biopsies were analysed for mRNA levels of selected genes, and GLUT4 and Akt protein content. Basal and insulin-stimulated Akt activation and tissue glucose uptake rates were also determined. In lean individuals, lipid turnover and insulin signalling genes (ACADM and IRS2) were up-regulated with FAST versus BFAST (ACADM: 1.14 (95% CI: 0.97-1.30) versus 0.80 (95% CI: 0.64-0.96), P = 0.007; IRS2: 1.75 (95% CI: 1.33 2.16) versus 1.09 (95% CI: 0.67-1.51), P = 0.03, respectively). In obese individuals, no differential (FAST versus BFAST) expression was observed in genes involved in lipid turnover (all P > 0.1). GLUT4, Akt protein content and insulin stimulated Akt phosphorylation were unaffected by FAST versus BFAST in both lean and obese cohorts (all P > 0.1). Lower insulin-stimulated glucose uptake rates in obese versus lean individuals were eradicated when normalised to whole-body fat mass (P = 0.416). We conclude that morning fasting up-regulates lipid turnover genes in SCAT of lean individuals. Secondly, altered SCAT insulin sensitivity with morning fasting is unlikely to be explained by signalling proximal to Akt. Finally, lower insulin-stimulated SCAT glucose uptake rates in obese individuals are proportional to whole-body fat mass, suggesting a compensatory down regulation, presumably to prevent excessive de novo lipogenesis in adipose tissue. This trial was registered as ISRCTN31521726. PMID- 29193094 TI - Expression of programmed death-1 in sentinel lymph nodes of breast cancer. AB - BACKGROUND AND OBJECTIVES: To explore whether lymphocytes in sentinel lymph nodes (SLNs) are highly exposed to tumor neoantigens and thus express high level of programmed death 1 (PD-1), we examined PD-1 expression in SLNs and non-sentinel regional lymph nodes (non-SLNs) in breast cancer. METHODS: We performed PD-1 immunohistochemistry in two cohorts: 40 metastasis-negative SLNs including 10 patients for each subtype (luminal A-like, luminal B-like, HER2, and triple negative breast cancer [TNBC]); and 25 pairs of metastasis-positive SLNs and non SLNs (10 luminal A-like, 10 luminal B-like, and 5 TNBC). RESULTS: Among 40 metastasis-negative SLNs, 34 and 6 samples were PD-1 intensity grade 1 (low) and 2 (high), respectively. PD-1 intensity correlated with PD-1-positive lymphocyte numbers (P = 0.005); TNBC had the highest PD-1 lymphocyte numbers among all subtypes. The median PD-1-positive lymphocyte number was higher in SLNs than non SLNs. In most cases, more lymphocytes in SLNs expressed PD-1 than those in non SLNs (P < 0.0001). CONCLUSIONS: TNBC had the greatest PD-1 expression among all subtypes, and metastasis-positive SLNs had more PD-1-positive lymphocytes than downstream non-SLNs. These data suggested that lymphocytes in SLNs are activated following exposure to tumor neoantigens and thus tumor specific, and could be utilized as a biomarker platform. PMID- 29193095 TI - Real-time detection system for tumor localization during minimally invasive surgery for gastric and colon cancer removal: In vivo feasibility study in a swine model. AB - BACKGROUND AND OBJECTIVES: During minimally invasive surgery (MIS), it is impossible to directly detect marked clips around tumors via palpation. Therefore, we developed a novel method and device using Radio Frequency IDentification (RFID) technology to detect the position of clips during minimally invasive gastrectomy or colectomy. METHODS: The feasibility of the RFID-based detection system was evaluated in an animal experiment consisting of seven swine. The primary outcome was to successfully detect the location of RFID clips in the stomach and colon. The secondary outcome measures were to detect time (time during the intracorporeal detection of the RFID clip), and accuracy (distance between the RFID clip and the detected site). RESULTS: A total of 25 detection attempts (14 in the stomach and 11 in the colon) using the RFID antenna had a 100% success rate. The median detection time was 32.5 s (range, 15-119 s) for the stomach and 28.0 s (range, 8-87 s) for the colon. The median detection distance was 6.5 mm (range, 4-18 mm) for the stomach and 6.0 mm (range, 3-13 mm) for the colon. CONCLUSIONS: We demonstrated favorable results for a RFID system that detects the position of gastric and colon tumors in real-time during MIS. PMID- 29193096 TI - Surgical treatment of pulmonic stenosis in dogs under cardiopulmonary bypass: outcome in nine dogs. AB - OBJECTIVES: To describe the outcome for nine dogs with pulmonic stenosis treated by open patch grafting using expanded polytetrafluoroethylene under cardiopulmonary bypass. MATERIALS AND METHODS: Data were collected from the hospital records of all dogs that had undergone right ventricular outflow tract grafting with an expanded polytetrafluoroethylene patch under cardiopulmonary bypass between 2006 and 2012 for the treatment of pulmonic stenosis. Echocardiographic images were reviewed and the pressure gradient across the right ventricular outflow tract re-measured. Owners of dogs still alive at the time of writing were invited to return to the hospital for reassessment. RESULTS: Nine dogs met the inclusion criteria. Median pressure gradient preoperatively was 118 mmHg, (range 102 to 259 mmHg) reducing to a median of 20 mmHg (range 7 to 53 mmHg) at 48 hours postoperatively and 14 mmHg (range 10 to 70 mmHg), with a median percentage reduction of 89% (range 41 to 94%) at long-term follow-up. Eight of nine dogs survived surgery, with six of nine surviving to hospital discharge. Two dogs were still alive over 6 and 8 years postoperatively. No long term deaths were believed to be attributable to pulmonic stenosis. CLINICAL SIGNIFICANCE: Expanded polytetrafluoroethylene patch grafting of the right ventricular outflow tract for treatment of severe pulmonic stenosis in dogs is feasible and can be an effective method to reduce the severity of right ventricular outflow tract obstruction. PMID- 29193097 TI - In vitro digestibility, free and bound phenolic profiles and antioxidant activity of thermally treated Eragrostis tef L. AB - BACKGROUND: Total phenolic content, phenolic profile and antioxidant activity were determined in free and bound phenolic fractions of thermally treated brown and white teff grains. RESULTS: Phenolic content in raw brown and white teff (1540 and 992 mg gallic acid equivalent kg-1 ) as well as antioxidant activity (6.3 and 5.5 mmol trolox equivalent kg-1 ) were higher in free phenolic fractions. The most significant decrease in total phenolics was observed after application of the sous-vide method (35% for brown teff and 11% for white teff). Main free phenolics of heat-treated teff were ferulic, protocatechuic, p-coumaric and ellagic acids, rutin and epigallocatechin. Main bound phenolics were ferulic, gallic, sinapic and ellagic acids, catechin and epigallocatechin. The detrimental effect on free and bound quercetin and bound cinnamic acid concentrations was also examined during heat treatment. Thermally treated brown teff showed a high level of in vitro organic matter digestibility if water cooking and rice cooker (both 99.5%) and sous-vide (96.5%) methods were applied. CONCLUSION: The sous vide method may be recommended as the most suitable hydrothermal treatment for grains of teff when compared with water cooking and rice cooker methods.

AB - Spindle epithelial tumor with thymus-like elements (SETTLE) is a rare and morphologically unique biphasic pediatric thyroid tumor of low malignant potential. There are less than 50 cases reported in the literature and few reported metastases. Despite the common usage of needle aspiration for thyroid and lymph node evaluation, cytologic descriptions of SETTLE are rare and tend to focus on a hypercellular biphasic appearance. We report aspirate findings of early cystic lymph node metastases in a 14-year-old girl, showing abundant matrix and low cellularity. We propose that the lack of recognition of this abundant matrix and cystic ultrasound appearance (as well as rarity of this tumor) may account for the low number of cytologic descriptions in the literature. Improved recognition may lead to increased usefulness of aspiration in the diagnosis and follow-up of SETTLE. Laryngoscope, 128:E78-E82, 2018. PMID- 29193098 TI - Factors associated with a primary surgical approach for sinonasal squamous cell carcinoma. AB - BACKGROUND AND OBJECTIVES: Primary surgery is the preferred treatment of T1-T4a sinonasal squamous cell carcinoma (SNSCC). METHODS: Patients with SNSCC in the National Cancer Data Base (NCDB) were analyzed. Factors that contributed to selecting primary surgical treatment were examined. Overall survival (OS) in surgical patients was analyzed. RESULTS: Four-thousand seven hundred and seventy patients with SNSCC were included. In T1-T4a tumors, lymph node metastases, maxillary sinus location, and treatment at high-volume centers were associated with selecting primary surgery. When primary surgery was utilized, tumor factors and positive margin guided worse OS. Adjuvant therapy improved OS in positive margin resection and advanced T stage cases. CONCLUSIONS: Tumor and non-tumor factors are associated with selecting surgery for the treatment of SNSCC. When surgery is selected, tumor factors drive OS. Negative margin resection should be the goal of a primary surgical approach. When a positive margin resection ensues, adjuvant therapy may improve OS.

AB - BACKGROUND: Depletion of haptoglobin (Hp) and hemopexin (Hx) with increase in free hemoglobin and heme are important etiologies of vaso-occlusive complications in sickle cell disease (SCD). This study is the first to show an association between clinical improvement in SCD and repletion of Hp and Hx by therapeutic plasma exchange (TPE) using plasma replacement. STUDY DESIGN AND METHODS: Thirteen fresh-frozen plasma (FFP) units derived from consecutive whole blood donations were thawed at 37 degrees C after 10 months of storage; Hp and Hx concentrations immediately postthaw and after 5 days of refrigerated storage were analyzed by enzyme-linked immunosorbent assay (ELISA). All SCD patients presenting to a single institution over a 2-year period with acute multiorgan failure syndrome resistant to red blood cell exchange (RCE) were treated with TPE with FFP replacement; concentrations of Hp, Hx, and heme were evaluated before and after TPE by ELISA. RESULTS: Plasma concentrations of Hp and Hx decreased approximately 20% (p <= 0.002) after 5 days of refrigerated storage. Significant mean fold increases after TPE of 10 for Hp (p < 0.005) and seven for Hx (p < 0.003) and a 30% mean decrease in heme concentrations (p = 0.07) were noted in association with clinical improvement (three patients), whereas minimal increases in Hp and Hx were associated with continued clinical deterioration in one patient. CONCLUSION: Fresh-frozen plasma rather than thawed plasma is optimal for Hp and Hx replacement. Patient data are consistent with Hp and Hx increases via TPE limiting clinical toxicity of worsened hemolysis associated with severe vaso occlusive complications refractory to RCE in SCD.

AB - BACKGROUND: Intravenous immunoglobulin (IVIG) has known efficacy in various hematologic conditions, including immune thrombocytopenic purpura. STUDY DESIGN AND METHODS: We present the clinical course of a patient with splenic marginal zone lymphoma, who developed acute thrombocytopenia on three consecutive episodes, with nadir counts of 27 * 109 , 50 * 109 , and 9 * 109 /L, upon administration of Intratect IVIG for hypogammaglobulinemia. An immunofluorescence test applying flow cytometry and monoclonal antibody immobilization of platelet antigens (MAIPA) assay were used to evaluate the reaction between IgG present in the IVIG preparations and the patient's or healthy donors' platelets (PLTs). RESULTS: A strong direct binding reaction was observed between the patient's PLTs and Intratect IgG using both methods. A similar reaction failed to materialize with controls. Binding was not antigen specific according to MAIPA. CONCLUSIONS: This is the first reported case of thrombocytopenia as a possible adverse effect of IVIG. PMID- 29193105 TI - Correlations between cystic fibrosis genotype and sinus disease severity in chronic rhinosinusitis. AB - OBJECTIVE: Cystic fibrosis (CF) patients commonly develop chronic rhinosinusitis (CRS). The impact of the most common cystic fibrosis transmembrane conductance regulator (CFTR) mutation, F508del, on the severity of sinonasal disease remains inconclusive. The objective of this study is to evaluate the impact of CFTR genotype functional classification on sinonasal disease severity in patients with CRS. METHODS: Retrospective chart review of patients with CF who underwent endoscopic sinus surgery for chronic rhinosinusitis from 1998 to 2015. Patients were divided into high- or low-risk genotypes based on standardized CFTR gene functional classification. The primary outcome was the 22-item Sino-Nasal Outcome Test (SNOT-22) score. Secondary outcomes included endoscopic scores, extent of surgery performed, presence of polyposis, number of revision surgeries, and Lund MacKay computed tomography scores. RESULTS: Thirty-eight patients harbored a high risk CFTR genotype, and 11 had a low-risk genotype. On bivariate analysis, there was no association between CFTR genotype risk stratification and measures of preoperative disease severity or postoperative outcomes. There were no associations between genotype risk stratification and outcome variables on multivariate linear regression, adjusted for age and gender. There were significant improvements in several SNOT-22 subdomains before and after endoscopic sinus surgery (P < 0.05), but the magnitude of improvement was not significantly different on the basis of CFTR genotype risk stratification. CONCLUSION: High-risk CFTR genotypes are not associated with worse sinonasal disease severity or postoperative symptom control than low-risk CFTR genotypes after adjusting for confounding factors.

AB - BACKGROUND: With more than 460 RHD alleles, this gene is the most complex and polymorphic among all blood group systems. The Tunisian population has the largest known prevalence of weak D Type 4.0 alleles, occurring in one of 105 RH haplotypes. We aimed to establish a rationale for the transfusion strategy of weak D Type 4.0 in Tunisia. STUDY DESIGN AND METHODS: Donors were randomly screened for the serologic weak D phenotype. The RHD coding sequence and parts of the introns were sequenced. To establish the RH haplotype, the RHCE gene was tested for characteristic single-nucleotide positions. RESULTS: We determined all RHD alleles and the RH haplotypes coding for the serologic weak D phenotype among 13,431 Tunisian donations. A serologic weak D phenotype was found in 67 individuals (0.50%). Among them, 60 carried a weak D Type 4 allele: 53 weak D Type 4.0, six weak D Type 4.2.2 (DAR), and one weak D Type 4.1. An additional four donors had one variant allele each: DVII, weak D Type 1, weak D Type 3, and weak D type 100, while three donors showed a normal RHD sequence. The weak D Type 4.0 was most often linked to RHCE*ceVS.04.01, weak D Type 4.2.2 to RHCE*ceAR, and weak D Type 4.1 to RHCE*ceVS.02, while the other RHD alleles were linked to one of the common RHCE alleles. CONCLUSIONS: Among the weak D phenotypes in Tunisia, no novel RHD allele was found and almost 90% were caused by alleles of the weak D Type 4 cluster, of which 88% represented the weak D Type 4.0 allele. Based on established RH haplotypes for variant RHD and RHCE alleles and the lack of adverse clinical reports, we recommend D+ transfusions for patients with weak D Type 4.0 in Tunisia.

AB - BACKGROUND: Rice is a special crop, and its production differs from that of other crops because it requires a thin layer of water coverage for a long period. The calculation of the water footprint of rice production should differ from that of other crops owing to the rice growing process. This study improved the calculation of blue and grey water footprints of rice production and analyzed the variations in the water footprints for rice production under different rainfall years in Jilin Province. RESULTS: In the drought year, the green water footprint was the lowest and the blue water footprint was the highest among the three years, while in the humid year, the green water footprint was the highest and the blue water footprint was not the lowest. The areas with higher water footprints were found in the east and west regions of Jilin Province, while the areas with lower water footprints were found in the middle east and middle regions of Jilin Province. CONCLUSION: Blue water was the primary water resource for rice production, although more precipitation provided the highest green water in the humid year; also, the spatial distributions of water footprints were not the same under different rainfall years.

AB - OBJECTIVES: Untreated dental caries can compromise oral health-related quality of life (OHRQoL). However, it is not clear which specific daily activities related to OHRQoL are compromised by the presence of this problem. Therefore, the purpose of this study was to identify which specific daily activities are affected by the presence of untreated dental caries using a representative sample of Brazilian children. METHODS: A cross-sectional study using a representative sample of Brazilian children (12 years of age) was conducted. The presence of untreated dental caries was assessed using the "decayed - D" component of the DMFT (decayed, missing, and filled teeth) index. Clinical exams were conducted by trained and calibrated dentists. The daily activities were evaluated using the survey Oral Impacts on Daily Performance (OIDP), considering items and domains. Descriptive, bivariate, and multiple analyses were conducted (alpha = 0.05). RESULTS: A total of 7,247 children were included, and 39.9 percent had at least one tooth with untreated dental caries, with 33.5 percent experiencing an impact on at least one of the OIDP activities. This study identified a greater chance of the presence of untreated dental caries in children having an impact on the psychological domain (P = 0.006), as well as on the "difficulty eating" (P = 0.007), and "difficulty sleeping" (P = 0.023) items. CONCLUSION: The presence of untreated dental caries among Brazilian children was associated with an impact on specific daily activities (difficulty eating and sleeping) and the psychological domain of OHRQoL. PMID- 29193109 TI - Skeletal Trauma Resulting From Fatal Low (<=3 m) Free Falls: An Analysis of Fracture Patterns and Morphologies. AB - The skeletal trauma resulting from fatal low (<=3 m) free falls is poorly researched and understood by forensic practitioners. The aim of this study was to identify the types of skeletal trauma resulting from low falls through investigating fracture patterns and morphologies. Skeletal trauma was analyzed using full-body postmortem computed tomography scans of 145 individuals who died from a low free fall. Trauma was then contextualized to the variables that influence how a person falls using multiple logistic regression. Results showed fracture patterning primarily involved the axial skeleton and that there were a number of patterns significantly associated with the height fallen, pre-existing health conditions, and age. Analysis of fracture morphologies showed 108 possible fracture types, six of which were significantly associated with the height fallen. Understanding the skeletal trauma characteristic of low free falls will further inform anthropological interpretations of trauma in cases where a fall may be considered the possible mechanism. PMID- 29193110 TI - Tinnitus and its risk factors in african americans: The Jackson Heart Study. AB - OBJECTIVES/HYPOTHESIS: To describe the prevalence of reported tinnitus and tinnitus handicap in the all-African American Jackson Heart Study (JHS) cohort, with assessment of the relationship to cardiometabolic risk and depression. STUDY DESIGN: Prospective cohort study. METHODS: Audiologic data were obtained from a sample of 1,314 participants of the JHS. Reported tinnitus was assessed dichotomously (yes/no) by interview and with the Tinnitus Handicap Inventory (THI). The statistical relationship of reported tinnitus and tinnitus handicap to various cardiometabolic risks (i.e., hypertension and waist circumference) and Center for Epidemiologic Studies Depression scale (CES-D) was assessed with logistic and gamma regression procedures. RESULTS: Tinnitus was found to be a highly prevalent condition (29.5%), with an additionally high rate of individuals who report at least slight tinnitus handicap (35%). Hypertension (beta = 1.344, 95% confidence interval [CI]: 1.015-1.780, P = .039) and waist circumference (beta = 1.009, 95% CI: 1.001-1.018, P = .021) were found to have a statistically significant relationship with THI score, depending on the level of covariate adjustment. Depression, as measured by the CES-D, was found to have a statistically significant relationship with both reported tinnitus (odds ratio [OR]: 1.051, 95% CI: 1.030-1.072, P < .001) and THI score (beta = 1.029, 95% CI: 1.013-1.047, P = .001), which persisted for all levels of covariate adjustment in statistical models. CONCLUSIONS: Tinnitus was found to be highly prevalent in the JHS, and certain measures of cardiometabolic risk are weakly related to both reported tinnitus and level of tinnitus handicap. A consistent relationship between depression and tinnitus/level of tinnitus handicap was observed. LEVEL OF EVIDENCE: 2b. Laryngoscope, 128:1668-1675, 2018. PMID- 29193112 TI - Prevalence of adult unilateral hearing loss and hearing aid use in the United States. AB - OBJECTIVE: The prevalence of unilateral hearing loss (UHL) in adults has not been well characterized. The objectives of this study are to determine the prevalence of UHL in U.S. adults and its treatment with hearing aids using a nationally representative study. STUDY DESIGN: Cross-sectional national epidemiologic study (n = 6,242). METHODS: Subjects >= 18 years old with audiometric testing in the 2005 to 2006, 2009 to 2010, and 2011 to 2012 cycles of the National Health and Nutrition Examination Study were included. UHL was defined as normal hearing (<=25 decibels hearing level [dB HL] pure tone average [PTA]) in one ear and at least mild hearing loss (>25 dB HL PTA) in the other ear. Hearing aid usage was defined by at least 5 hours per week (2005-2006) or at least seldom (2009-2012) use. Sampling weights were utilized to ensure generalizability to the U.S. POPULATION: RESULTS: The overall prevalence of UHL in adult Americans was 7.2% (95% confidence interval 6.1%-8.6%), with 5.7% (4.8%-6.7%) having mild and 1.5% (0.1%-2.1%) with moderate-or-worse UHL; nearly one-third of the latter reported trouble hearing. The prevalence of hearing aid usage in those with UHL was 2.0% (0.6%-6.7%). Of those with mild UHL, 1.4% (0.2%-8.0%) used hearing aids. Of those with moderate UHL, 4.2% (0.1%-22%) used hearing aids. Among those with UHL and also at least moderate subjective difficulty hearing, only 11% wore hearing aids. CONCLUSION: UHL is common among U.S. adults. Hearing aid usage is very low, even when there is perceived handicap. Public health education is needed to increase awareness of and auditory rehabilitation for UHL. LEVEL OF EVIDENCE: 2.

PMID- 29193111 TI - Clinical input of anti-D quantitation by continuous-flow analysis on autoanalyzer in the management of high-titer anti-D maternal alloimmunization. AB - BACKGROUND: In addition to titration by indirect antiglobulin test most widely used, anti-D quantitation by continuous-flow analysis (CFA) may be performed to assess severity of maternal immunization. Only five studies have reported its added value in the management of pregnancies complicated by anti-D immunization. STUDY DESIGN AND METHODS: A retrospective study of 74 severe anti-D-immunized pregnancies was conducted from January 1, 2013, to December 31, 2014, in the Trousseau Hospital in Paris (France). Concentration of maternal anti-D was measured by titration and by CFA two-stages method (2SM; total amount of anti-D) and one-stage method (1SM; high-affinity IgG1 anti-D). These biologic data were analyzed according to the severity of the hemolytic disease of the fetus and the newborn. RESULTS: The value of 5 IU anti-D/mL in maternal serum is validated as a threshold to trigger ultrasonographic and Doppler fetal close follow-up. A high 1SM/2SM ratio was associated with a higher risk of intrauterine transfusion (IUT). For pregnancies requiring IUT and without increasing titer, maternal 1SM anti-D concentration tends to correlate with the precocity of fetal anemia. In the "without-IUT" group 1SM and 2SM anti-D concentrations correlate significantly with cord bilirubin levels of the newborn at birth. CONCLUSION: Altogether our results underline the importance of anti-D quantitation by CFA to optimize the management of anti-D-alloimmunized pregnancies.

PMID- 29193117 TI - The development of D antibodies after D-mismatched kidney transplantation in a setting of reduced immunosuppression. AB - BACKGROUND: D antigens are not taken into account in the allocation of solid organs. Female transplant recipients with D antibodies as a consequence of D mismatched kidney transplantation may develop hemolytic disease of the fetus and newborn in future pregnancies. We examined D antibody development in transplant recipients who received D-mismatched kidney transplantation in absence of D prophylaxis and in a setting of reduced immunosuppression. STUDY DESIGN AND METHODS: From 1993 until 2015, a total of 1355 kidney patients received transplantations in our center of whom 156 received a D-mismatched graft. A retrospective analysis was conducted; frozen stored sera obtained from transplant recipients 3 months after transplantation were tested for irregular red blood cell (RBC) antibodies using a three-cell screening and an identification panel. In the case of D antibody positivity, additional testing was performed 1 month before transplantation. RESULTS: In seven of 156 (4.5%) transplant recipients we found irregular RBC antibodies after transplantation, of which five (3.2%) were determined to be D antibodies. We observed only one (0.6%) recipient without D antibodies before transplantation. CONCLUSION: Although the risk of D antibody development is considerably lower after D-mismatched kidney transplantation than D-mismatched pregnancy, anti-D prophylaxis may still be advisable for female transplant recipients of childbearing age. PMID- 29193118 TI - In premature infants there is no decrease in 24-hour posttransfusion allogeneic red blood cell recovery after 42 days of storage. AB - BACKGROUND: Critically ill preterm very-low-birthweight (VLBW) neonates (birthweight <= 1.5 kg) frequently develop anemia that is treated with red blood cell (RBC) transfusions. Although RBCs transfused to adults demonstrate progressive decreases in posttransfusion 24-hour RBC recovery (PTR24 ) during storage-to a mean of approximately 85% of the Food and Drug Administration allowed 42-day storage-limited data in infants indicate no decrease in PTR24 with storage. STUDY DESIGN AND METHODS: We hypothesized that PTR24 of allogeneic RBCs transfused to anemic VLBW newborns: 1) will be greater than PTR24 of autologous RBCs transfused into healthy adults and 2) will not decrease with increasing storage duration. RBCs were stored at 4 degrees C for not more than 42 days in AS 3 or AS-5. PTR24 was determined in 46 VLBW neonates using biotin-labeled RBCs and in 76 healthy adults using 51 Cr-labeled RBCs. Linear mixed-model analysis was used to estimate slopes and intercepts of PTR24 versus duration of RBC storage. RESULTS: For VLBW newborns, the estimated slope of PTR24 versus storage did not decrease with the duration of storage (p = 0.18) while for adults it did (p < 0.0001). These estimated slopes differed significantly in adults compared to newborns (p = 0.04). At the allowed 42-day storage limit, projected mean neonatal PTR24 was 95.9%; for adults, it was 83.8% (p = 0.0002). CONCLUSIONS: These data provide evidence that storage duration of allogeneic RBCs intended for neonates can be increased without affecting PTR24 . This conclusion supports the practice of transfusing RBCs stored up to 42 days for small-volume neonatal transfusions to limit donor exposure. PMID- 29193119 TI - Evaluation of the applicability and effectiveness of a molecular strategy for identifying weak D and DEL phenotype among D- blood donors of mixed origin exhibiting high frequency of RHD*Psi. AB - BACKGROUND: Molecular tests designed to detect the presence of active RHD gene among D- donors have been successfully applied in people of European ancestry, but not in admixed populations with a considerable frequency of RHD*Psi. Our goal was to evaluate the performance of a molecular screening tool for identifying active RHD alleles among Brazilian blood donors classified as D- C+ and/or E+. STUDY DESIGN AND METHODS: Pools of five DNA samples of serologically D- C+ and/or E+ donors were checked by a RHD polymerase chain reaction (PCR) assay specific for RHD Intron 4 and Exon 7. When a pool result was positive, samples were genotyped individually for RHD Intron 4 and Exon 7, RHD*Psi, RHCE*Cc, and RHD zygosity. Donors suspected of active RHD gene were further evaluated by whole coding region and flanking intron direct sequencing. RESULTS: A total of 405 donors were included. Two percent exhibited active RHD gene, codifying D-weak (38 and 45) or DEL phenotype. The most prevalent DEL allele was RHD*DEL1 (c.1227G>A), which is proven to be immunogenic. A high frequency of RHD*Psi was detected in the donors with nondeleted RHD alleles (31%), far superior to the frequency of RHD variant alleles (15.5%). The proposed approach presented sensitivity of 100% and specificity of 85.7% for identifying active RHD gene. CONCLUSION: The strategy of checking D- donors with RHD PCR followed by exclusion of RHD*Psi allele has proved efficient in identifying weak-D and DEL phenotype in the Brazilian population. PMID- 29193120 TI - The role of elective neck dissection in the treatment of maxillary sinus squamous cell carcinoma. AB - OBJECTIVE: This study is designed to analyze the survival benefits of elective neck dissection (END) in the treatment of squamous cell carcinoma of the maxillary sinus (MS-SCC) with clinically negative neck lymph nodes (N0) and no metastasis (M0). STUDY DESIGN: The aim of this study was to evaluate whether END improves survival in patients with MS-SCC. METHODS: This study is a population based, concurrent retrospective database analysis of patients diagnosed with N0M0 MS-SCC from 2004 to 2013. Data were acquired from the Surveillance, Epidemiology, and End Results database. Frequency functions, Kaplan-Meier and Cox regression models were queried to analyze demographics, treatment status, and survival outcomes. RESULTS: There were a total of 927 MS-SCC cases in the database between 2004 and 2013. This analysis revealed that for the overall cohort, END significantly and independently reduces the 5-year hazard of death in MS-SCC (hazard ratio [HR] = 0.646, 95% confidence interval [CI] = 0.419-0.873, P = 0.047). For early tumor (T)1/T2 tumors and T4 tumors, END did not independently improve 5-year survival. However, for T3 disease, END significantly reduced the 5 year hazard of death in MS-SCC (HR = 0.471, 95% CI = 0.261-0.680, P = 0.001), regardless of other covariates, including adjuvant radiation. There has been an increase in the percentage of MS-SCC surgeries that have been accompanied by END since SEER started collecting this data, although this did not demonstrate significance (R2 = 0.622). CONCLUSION: END improves disease-specific survival in patients with MS-SCC size > 4 cm and advanced T-stage (American Joint Committee on Cancer AJCC TIII). Therefore, surgeons performing maxillectomies should consider conducting an END concurrent with maxillectomy for those with size > 4 cm advanced stage cancer. LEVEL OF EVIDENCE: 4.

AB - Recent studies on post-fire tree mortality suggest a role for heat-induced alterations of the hydraulic system. We analyzed heat effects on xylem hydraulics both in the laboratory and at a forest site hit by fire. Stem vulnerability to drought-induced embolism and hydraulic conductivity were measured in Picea abies, Pinus sylvestris and Fagus sylvatica. Control branches were compared with samples experimentally exposed to 90 degrees C or damaged by a natural forest fire. In addition, xylem anatomical changes were examined microscopically. Experimental heating caused structural changes in the xylem and increased vulnerability in all species. The largest shifts in vulnerability thresholds (1.3 MPa) were observed in P. sylvestris. F. sylvatica also showed heat-induced reductions (49%) in hydraulic conductivity. At the field site, increased vulnerability was observed in damaged branches of P. sylvestris and F. sylvatica, and the xylem of F. sylvatica was 39% less conductive in damaged than in undamaged branches. These results provide evidence for heat-induced impairment of tree hydraulics after fire. The effects recorded at the forest fire site corresponded to those obtained in laboratory experiments, and revealed pronounced hydraulic risks in P. sylvestris and F. sylvatica. Knowledge of species-specific hydraulic impairments induced by fire and heat is a prerequisite for accurate estimation of post-fire mortality risks. PMID- 29193123 TI - Physiologically Based Pharmacokinetic Modeling to Evaluate the Systemic Exposure of Gefitinib in CYP2D6 Ultrarapid Metabolizers and Extensive Metabolizers. AB - Gefitinib is a selective inhibitor of epidermal growth factor receptor (EGFR) tyrosine kinase and is used for the treatment of non-small-cell lung cancer (NSCLC) with activating EGFR mutations. Gefitinib is metabolized by CYP2D6 and CYP3A4. This analysis compared the systemic exposure of gefitinib after oral administration in CYP2D6 ultrarapid metabolizers (UM) vs extensive metabolizers (EM). Physiologically based pharmacokinetic (PBPK) modeling was conducted using a population-based simulator. The model was calibrated using itraconazole-gefitinib clinical drug-drug interaction data and validated with gefitinib data in CYP2D6 EM vs poor metabolizers (PM). System components of the PBPK model were evaluated using published clinical metoprolol pharmacokinetic data in CYP2D6 UM, EM, and PM. Our PBPK model predicted a gefitinib geometric least-squares mean area under the plasma concentration-time curve (AUC) from time 0 to 264 hours (AUC(0-264) ) ratio in the presence vs absence of itraconazole of 1.85, similar to the ratio of 1.78 from clinical study data. Predicted and observed metoprolol geometric least squares mean AUC(0-24) ratios in UM vs EM were also similar (0.46 and 0.55, respectively), suggesting that system components related to CYP2D6 in the PBPK model were properly established. In addition, the PBPK model also captured gefitinib pharmacokinetic profiles in CYP2D6 polymorphic populations. The final PBPK model predicted a decrease in gefitinib AUC of ~39% in CYP2D6 UM vs EM. Such changes in exposure will have limited impact as the reduced exposure is still above gefitinib's in vitro IC90 for EGFR activating mutations in NSCLC patients. PMID- 29193124 TI - Prediction of benzo[a]pyrene content of smoked sausage using back-propagation artificial neural network. AB - BACKGROUND: Benzo[a]pyrene (BaP), a potent mutagen and carcinogen, is reported to be present in processed meat products and, in particular, in smoked meat. However, few methods exist for predictive determination of the BaP content of smoked meats such as sausage. In this study, an artificial neural network (ANN) model based on the back-propagation (BP) algorithm was used to predict the BaP content of smoked sausage. RESULTS: The results showed that the BP network based on the Levenberg-Marquardt algorithm was the best suited for creating a nonlinear map between the input and output parameters. The optimal network structure was 3 7-1 and the learning rate was 0.6. This BP-ANN model allowed for accurate predictions, with the correlation coefficients (R) for the experimentally determined training, validation, test and global data sets being 0.94, 0.96, 0.95 and 0.95 respectively. The validation performance was 0.013, suggesting that the proposed BP-ANN may be used to predictively detect the BaP content of smoked meat products. CONCLUSION: An effective predictive model was constructed for estimation of the BaP content of smoked sausage using ANN modeling techniques, which shows potential to predict the BaP content in smoked sausage.

AB - Elevated tropospheric ozone (O3 ) concentration has been shown to affect many aspects of plant performance including detrimental effects on leaf photosynthesis and plant growth. However, it is not known whether such changes are accompanied by concomitant responses in plant hydraulic architecture and water relations, which would have great implications for plant growth and survival in face of unfavorable water conditions. A soybean (Glycine max (L.) Merr.) cultivar commonly used in Northeast China was exposed to non-filtered air (NF, averaged 24.0 nl l-1 ) and elevated O3 concentrations (eO3 , 40 nl l-1 supplied with NF air) in six open-top chambers for 50 days. The eO3 treatment resulted in a significant decrease in whole-plant hydraulic conductance that is mainly attributable to the reduced hydraulic conductance of the root system and the leaflets, while stem and leaf petiole hydraulic conductance showed no significant response to eO3 . Stomatal conductance of plants grown under eO3 was lower during mid-morning but significantly higher at midday, which resulted in substantially more negative daily minimum water potentials. Moreover, excised leaves from the eO3 treated plants showed significantly higher rates of water loss, suggesting a lower ability to withhold water when water supply is impeded. Our results indicate that, besides the direct detrimental effects of eO3 on photosynthetic carbon assimilation, its influences on hydraulic architecture and water relations may also negatively affect O3 -sensitive crops by deteriorating the detrimental effects of unfavorable water conditions. PMID- 29193126 TI - Pharmacokinetics and Pharmacodynamics of Azeloprazole Sodium, a Novel Proton Pump Inhibitor, in Healthy Japanese Volunteers. AB - The pharmacokinetics (PK) and pharmacodynamics (PD) of proton pump inhibitors differ among cytochrome P450 (CYP) 2C19 genotypes. Therefore, we developed azeloprazole sodium (Z-215), a novel proton pump inhibitor, whose metabolism is not affected by CYP2C19 activity in vitro. However, the PK and PD of azeloprazole sodium have not been evaluated in Japanese subjects. We conducted an open-label, crossover study in healthy Japanese male volunteers to evaluate the plasma concentration and intragastric pH with respect to CYP2C19 genotype after repeated administration of 10, 20, and 40 mg azeloprazole sodium and 10 and 20 mg rabeprazole sodium (rabeprazole). The plasma concentration profile of azeloprazole sodium was similar among genotypes, whereas that of rabeprazole differed. The 24-hour intragastric pH >= 4 holding time ratio (pH >= 4 HTR) of azeloprazole sodium was similar among genotypes. The pH >= 4 HTR was 52.5%-60.3%, 55.1%-65.8%, and 69.4%-77.1% after administration of 10, 20, and 40 mg azeloprazole sodium, respectively, and 59.2%-72.3% and 64.4%-91.2% after administration of 10 and 20 mg rabeprazole, respectively, on the fifth day of dosing. The maximum plasma concentration (Cmax ), area under the plasma concentration-time curve (AUC), and pH >= 4 HTR of azeloprazole sodium were proportional to dose. The Cmax , AUC, and pH >= 4 HTR on day 5 were slightly higher following administration of 20 mg azeloprazole sodium before comparison with after a meal. No serious adverse events were observed. These results suggest that azeloprazole sodium is useful for treating gastroesophageal reflux disease in all CYP2C19 genotypes. PMID- 29193127 TI - Pregnancy and perinatal conditions and atopic disease prevalence in childhood and adulthood. AB - BACKGROUND: Previous studies showed controversial results for the influence of pregnancy-related and perinatal factors on subsequent respiratory and atopic diseases in children. The aim of this study was to assess the association between perinatal variables and the prevalence of asthma, bronchial hyperreactivity (BHR), flexural eczema (FE), allergic rhinitis, and sensitization in childhood and early adulthood. METHODS: The studied population was first examined in Munich and Dresden in 1995/1996 at age 9-11 years. Participants were followed until age 19-24 years using questionnaires and clinical examinations. Associations between perinatal data and subsequent atopic diseases were examined using logistic regression analyses adjusting for potential confounders. RESULTS: Cesarean section was statistically significantly associated with BHR in early adulthood (odds ratio 4.8 [95% confidence interval 1.5-15.2]), while assisted birth was associated with presence of asthma symptoms in childhood (2.2 [1.2-3.9]), FE symptoms (2.2 [1.2-4.3]) and doctor's diagnosis of atopic dermatitis (1.9 [1.0 3.4]) in childhood, and sensitization in early adulthood (2.2 [1.1-4.3]). Lower birth length (1.9 [1.1-3.2]), lower birthweight (0.5 [0.3-0.9]), and higher birthweight (0.6 [0.4-1.0]) were predictive of sensitization in early adulthood compared to average birth length and birthweight, respectively. None of the other perinatal factors showed statistically significant associations with the outcomes. CONCLUSIONS: Our results indicate that children who are born by cesarean section and especially by assisted birth, might be at greater risk for developing asthma, FE, and sensitization and should hence be monitored. Prenatal maternal stress might partly explain these associations, which should be further investigated. PMID- 29193128 TI - Pathogen reduction and blood transfusion safety in Africa: strengths, limitations and challenges of implementation in low-resource settings. AB - Transfusion-transmitted infection risk remains an enduring challenge to blood safety in Africa. A high background incidence and prevalence of the major transfusion-transmitted infections (TTIs), dependence on high-risk donors to meet demand, suboptimal testing and quality assurance collectively contribute to the increased risk. With few exceptions, donor testing is confined to serological evaluation of human immunodeficiency virus (HIV), hepatitis B and C (HBV and HCV) and syphilis. Barriers to implementation of broader molecular methods include cost, limited infrastructure and lack of technical expertise. Pathogen reduction (PR), a term used to describe a variety of methods (e.g. solvent detergent treatment or photochemical activation) that may be applied to blood following collection, offers the means to diminish the infectious potential of multiple pathogens simultaneously. This is effective against different classes of pathogen, including the major TTIs where laboratory screening is already implemented (e.g. HIV, HBV and HCV) as well pathogens that are widely endemic yet remain unaddressed (e.g. malaria, bacterial contamination). We sought to review the available and emerging PR techniques and their potential application to resource-constrained parts of Africa, focusing on the advantages and disadvantages of such technologies. PR has been slow to be adopted even in high income countries, primarily given the high costs of use. Logistical considerations, particularly in low-resourced parts of Africa, also raise concerns about practicality. Nonetheless, PR offers a rational, innovative strategy to contend with TTIs; technologies in development may well present a viable complement or even alternative to targeted screening in the future. PMID- 29193129 TI - A model observer study using acquired mammographic images of an anthropomorphic breast phantom. AB - PURPOSE: To study the feasibility of a task-based framework composed of an anthropomorphic breast phantom and mathematical model observers (MOs) for the evaluation of system-processed mammographic images. METHODS: A prototype anthropomorphic breast phantom with inserted gold discs of 0.1 mm and 0.25 mm diameter was imaged with two digital mammography systems (system A and B) at four different dose levels. From the acquired processed and unprocessed images, signal present and signal-absent regions of interest (ROIs) were extracted. The ROIs were evaluated by a non-pre-whitening MO with eye filter (NPWE) and by three human observers in a two-alternative forced-choice experiment. We compared the human and the MO performance on a simple detection task of the calcification-like discs in ROIs with and without postprocessing. Proportion of correct responses of the human (PCH ) and NPWE (PCNPWE ) experiments was calculated and the correlation between the two was analyzed using a mixed-effect regression model. Correlation results including the goodness of fit (r2 ) of PCH and PCNPWE for all different parameters investigated were evaluated to determine whether NPWE MO can be used to predict human observer performance. RESULTS: PCH and PCNPWE increased with dose for all conditions investigated (signal size, processing status, and different system). In case of the 0.1 mm discs, for system A, r2 between PCH with PCNPWE was 0.81. For system B, r2 was 0.93. In case of the 0.25 mm discs, r2 in system A was 0.79 and for system B, r2 was 0.82. For the combined parameters investigated, and after excluding the 0.1 mm discs on system A because the results were influenced by aliasing, the overall r2 was 0.81. Image processing did not affect the detectability of calcification-like signals. No significant difference (P > 0.05) was found between the predicted PCH(pred) by the MO and the PCH for all different conditions. CONCLUSIONS: The framework seems promising to be used in objective image quality assessment. It was found to be relatively robust for the range of parameters investigated. However, further optimization of the anthropomorphic breast phantom and investigation of other MOs for a broader range of image quality assessment tasks is needed. PMID- 29193130 TI - Evaluation of a lateral flow-based technology card for blood typing using a simplified protocol in a model of extreme blood sampling conditions. AB - BACKGROUND: Life-threatening situations requiring blood transfusion under extreme conditions or in remote and austere locations, such as the battlefield or in traffic accidents, would benefit from reliable blood typing practices that are easily understood by a nonscientist or nonlaboratory technician and provide quick results. STUDY DESIGN AND METHODS: A simplified protocol was developed for the lateral flow-based device MDmulticard ABO-D-Rh subgroups-K. Its performance was compared to a reference method (PK7300, Beckman Coulter) in native blood samples from donors. The method was tested on blood samples stressed in vitro as a model of hemorrhage cases (through hemodilution using physiologic serum) and dehydration (through hemoconcentration by removing an aliquot of plasma after centrifugation), respectively. RESULTS: A total of 146 tests were performed on 52 samples; 126 in the hemodilution group (42 for each native, diluted 1/2, and diluted 1/4 samples) and 20 in the hemoconcentration group (10 for each native and 10% concentrated samples). Hematocrit in the tested samples ranged from 9.8% to 57.6% while hemoglobin levels ranged from 3.2 to 20.1 g/dL. The phenotype profile detected with the MDmulticard using the simplified protocol resulted in 22 A, seven B, 20 O, and three AB, of which nine were D- and five were Kell positive. No discrepancies were found with respect to the results obtained with the reference method. CONCLUSION: The simplified protocol for MDmulticard use could be considered a reliable method for blood typing in extreme environment or emergency situations, worsened by red blood cell dilution or concentration.

PMID- 29193136 TI - Clinical indications for intravenous immunoglobulin utilization in a tertiary medical center: a 9-year retrospective study. AB - BACKGROUND: Intravenous immunoglobulins (IVIG) are a biologic product originally developed to treat immunocompromised patients. In the past decades, there has been increased utilization of IVIG in autoimmune conditions. The objectives were to evaluate the clinical use of IVIG in the largest tertiary medical center in Israel and to determine top uses, estimate off-label usage, and assess consumption of this blood product. STUDY DESIGN AND METHODS: We conducted an observational, retrospective study involving all patients who received IVIG from 2007 through 2015. Subjects were classified into five groups according to the indication for treatment. RESULTS: A total of 1117 patients were identified. The mean (+/-SD) ages of adults and children were 55 +/- 17 and 8 +/- 7 years, respectively. Most common indication for treatment were immune-mediated conditions (54%), followed by secondary immunodeficiency (28%), primary immunodeficiency (10%), infections (4%), and miscellaneous (4%). The main immune mediated conditions treated were hematologic disorders (305 patients, 27%), neurologic disorders (219 patients, 20%), and rheumatologic conditions (79 patients, 7%). Overall, a significant change in study period was observed in the number of patients (p < 0.001), consumption of IVIG (p < 0.01), and amount of IVIG administered per patient (p < 0.01). Fifty-six percent of the IVIG infusions were given for off-label Food and Drug Administration (FDA) indications. CONCLUSION: In this study, we demonstrated that immune-mediated conditions represent the majority of indications for treatment with IVIG. We observed a 417% increase in IVIG administration (g) over time, attributed mainly to autoimmune diseases. Many indications are still off-label according to FDA recommendations.

PMID- 29193138 TI - Intranasal immunization with phosphorylcholine suppresses allergic rhinitis in mice. AB - OBJECTIVES/HYPOTHESIS: Intranasal immunization with phosphorylcholine (PC) is known to reduce immunoglobulin (Ig)E production. However, its effects on the occurrence of allergic rhinitis (AR) are unknown. This study was performed to evaluate the effects of PC-keyhole limpet hemocyanin (PC-KLH) and to examine the effects on the occurrence of AR in a murine model of AR. STUDY DESIGN: In vivo study using an animal model. METHODS: Forty-five female BALB/c mice were divided into three groups; those pretreated with intranasal administration of PC-KLH followed by intraperitoneal sensitization and nasal challenge with ovalbumin (OVA) (group A), those untreated with PC-KLH followed by sensitization and nasal challenge with OVA (group B), and those untreated with PC-KLH or OVA as controls (group C). Nasal symptoms, allergic inflammation in the nasal mucosa, OVA specific IgE production, and cytokine profile were compared among those three groups. Dendritic cells (DCs) were isolated from splenic cells and PC-KLH stimulated interleukin (IL)-12p40 production was measured. RESULTS: The mice pretreated with PC-KLH showed lower allergic nasal symptoms and inflammation compared to untreated mice. The levels of total IgE and OVA-specific IgE in serum, and IL-4 production by nasal and splenic CD4+ T cells were significantly reduced by PC-KLH pretreatment. Furthermore, IL-12p40 production by DCs was induced by PC-KLH in a dose-dependent manner. CONCLUSIONS: Intranasal administration of PC-KLH suppressed allergic inflammation in nasal mucosa and antigen-specific IgE production by downregulating Th2-type immune response. Intranasal immunization with PC might be useful to prevent AR and upper airway bacterial infection. LEVEL OF EVIDENCE: NA. Laryngoscope, 128:E234-E240, 2018. PMID- 29193140 TI - Erratum.

AB - Binge drinking is widespread on American college campuses, but its effects on the cardiovascular system are poorly understood. This study sought evidence of preclinical cardiovascular changes in binge drinking young adults (n = 24) compared to nondrinking (n = 24) and social drinking (n = 23) peers during baseline, paced sighing (0.033 Hz), and paced breathing (0.1 Hz) tasks. Binge drinkers showed consistent but often statistically nonsignificant evidence of greater sympathetic activation and reduced baroreflex sensitivity. Interestingly, the structure of group-averaged baseline heart rate spectra was considerably different between groups in the low frequency range (0.05-0.15 Hz). In particular, the binge drinking group-averaged spectra showed several spectral peaks not evident in the other groups, possibly indicating two functionally distinct subranges (0.05-0.08 and 0.08-0.15 Hz) that reflect vascular tone baroreflex activity and heart rate baroreflex activity, respectively. Vascular tone baroreflex gain and power in two peaks in the 0.05-0.08 Hz range were associated with years of drinking in the binge drinking group. Vascular dysfunction may be an early indicator of drinking-related change in the cardiovascular system. PMID- 29193141 TI - Behavioral variability as avoidance behavior. AB - This study aimed to investigate whether variable patterns of responses can be acquired and maintained by negative reinforcement under an avoidance contingency. Six male Wistar rats were exposed to sessions in which behavioral variability was reinforced according to a Lag contingency: Sequences of three responses on two levers had to differ from one, two or three previous sequences for shocks to be avoided (Lag 1, Lag 2 and Lag 3, respectively). Performance under the Lag conditions was compared with performance on a Yoke condition in which the animals received the same reinforcement frequency and distribution as in the Lag condition but behavioral variability was not required. The results showed that most of the subjects varied their sequences under the Lag contingencies, avoiding shocks with relatively high probability (>= 0.7). Under the Yoke procedure, responding continued to occur with high probability, but the behavioral variability decreased. These results suggest that behavioral variability can be negatively reinforced.

AB - OBJECTIVE: This study was performed to assess the anti-inflammatory and anti apoptotic effects of the combination of Ligusticum chuanxiong and Radix Paeoniae (XS) on focal cerebral ischaemic stroke. METHODS: MCAO rats were used to evaluate the effect of XS on stroke. Cerebral water content was measured, and the levels of IFN-gamma, IL-1beta, IL-6 and IL-12 in serum and brain were assessed by ELISA kits. Protein expressions including p-p38, p-38, TLR-4, p-ERK, ERK, TLR-5, NF kappaBp65, Myd88, Caspase-3 and Caspase-12 were examined by WB and IHC. Q-PCR was applied to examine IL-1beta and IL-6 mRNA levels in the rat brain of each group. KEY FINDINGS: XS treatment remarkedly decreased the levels of IFN-gamma, IL 1beta, IL-6 and IL-12 in serum and brain tissues of MCAO rats. In the ischaemic brain, the expressions of TLR-4, TLR-5, p-p38, p-ERK, Myd88, NF-kappaBp65, Caspase-3 and Caspase-12 were increased significantly, while the treatment attenuated the activated expressions by MCAO. XS also downregulated Caspase-3 and Caspase-12 expressions. IL-1beta and IL-6 mRNA levels in MCAO brain tissue were decreased by XS treatment. CONCLUSIONS: XS could protect MCAO rats by anti inflammation and anti-apoptosis through TLR4/MyD88/MAPK/NF-kappaB signalling pathway. Furthermore, the combination has a more meaningful improvement on focal cerebral ischaemic stroke. PMID- 29193144 TI - Simulating thermal effects of MR-guided focused ultrasound in cortical bone and its surrounding tissue. AB - PURPOSE: Magnetic resonance-guided focused ultrasound (MRgFUS) is emerging as a treatment alternative for osteoid osteoma and painful bone metastases. This study describes a new simulation platform that predicts the distribution of heat generated by MRgFUS when applied to bone tissue. METHODS: Calculation of the temperature distribution was performed using two mathematical models. The first determined the propagation and absorption of acoustic energy through each medium, and this was performed using a multilayered approximation of the Rayleigh integral method. The ultrasound energy distribution derived from these equations could then be converted to heat energy, and the second mathematical model would then use the heat generated to determine the final temperature distribution using a finite-difference time-domain application of Pennes' bio-heat transfer equation. Anatomical surface geometry was generated using a modified version of a mesh-based semiautomatic segmentation algorithm, and both the acoustic and thermodynamic models were calculated using a parallelized algorithm running on a graphics processing unit (GPU) to greatly accelerate computation time. A series of seven porcine experiments were performed to validate the model, comparing simulated temperatures to MR thermometry and assessing spatial, temporal, and maximum temperature accuracy in the soft tissue. RESULTS: The parallelized algorithm performed acoustic and thermodynamic calculations on grids of over 108 voxels in under 30 s for a simulated 20 s of heating and 40 s of cooling, with a maximum time per calculated voxel of less than 0.3 MUs. Accuracy was assessed by comparing the soft tissue thermometry to the simulation in the soft tissue adjacent to bone using four metrics. The maximum temperature difference between the simulation and thermometry in a region of interest around the bone was measured to be 5.43 +/- 3.51 degrees C average absolute difference and a percentage difference of 16.7%. The difference in heating location resulted in a total root-mean-square error of 4.21 +/- 1.43 mm. The total size of the ablated tissue calculated from the thermal dose approximation in the simulation was, on average, 67.6% smaller than measured from the thermometry. The cooldown was much faster in the simulation, where it decreased by 14.22 +/- 4.10 degrees C more than the thermometry in 40 s after sonication ended. CONCLUSIONS: The use of a Rayleigh-based acoustic model combined with a discretized bio-heat transfer model provided a rapid three-dimensional calculation of the temperature distribution through bone and soft tissue during MRgFUS application, and the parallelized GPU algorithm provided the computational speed that would be necessary for an intraoperative treatment planning software platform. PMID- 29193145 TI - Polyethylene glycol as marker for nitrofurazone allergy: 20 years of experience from Turkey. AB - BACKGROUND: Polyethylene glycols (PEGs) and propylene glycol (PG) are used as vehicles in various medicinal and cosmetic products. They are potential contact sensitizers, including low molecular weight PEGs in nitrofurazone preparations that are still widely used in Turkey. OBJECTIVES: To investigate the prevalence of allergic contact dermatitis caused by PEG and PG in a relatively large group of patients in Turkey. METHODS: In this retrospective, cross-sectional, single centre study, 836 patients patch tested with PEG and PG between 1996 and 2015 were reviewed. RESULTS: Thirty-five patients (4.2%) showed positive patch test reactions to PEG, and 7 (0.8%) showed positive patch test reactions to PG, partly as late positive reactions with PEG. PEG sensitivity was almost exclusively related to nitrofurazone allergy. Patch test reactions to PG were currently relevant mainly with regard to the use of minoxidil, and antiherpetic or corticosteroid creams. Ten patients (25%) had concomitant contact allergies to various topical drugs containing mainly PEGs. CONCLUSIONS: PEG sensitivity seems to be a marker for contact allergy to topical nitrofurazone in Turkey. Nitrofurazone allergy appears to favour concomitant sensitization to PEG. We would suggest the inclusion of PEG in an extended baseline patch test series in Turkey. Late patch test readings are important to diagnose delayed positive reactions to PEG.

PMID- 29193148 TI - Multi-gene phylogeny of jacks and pompanos (Carangidae), including placement of monotypic vadigo Campogramma glaycos. AB - In this study, the phylogenetic trees of jacks and pompanos (Carangidae), an ecologically and morphologically diverse, globally distributed fish family, are inferred from a complete, concatenated data set of two mitochondrial (cytochrome c oxidase I, cytochrome b) loci and one nuclear (myosin heavy chain 6) locus. Maximum likelihood and Bayesian inferences are largely congruent and show a clear separation of Carangidae into the four subfamilies: Scomberoidinae, Trachinotinae, Naucratinae and Caranginae. The inclusion of the carangid sister lineages Coryphaenidae (dolphinfishes) and Rachycentridae (cobia), however, render Carangidae paraphyletic. The phylogenetic trees also show with high statistical support that the monotypic vadigo Campogramma glaycos is the sister to all other species within the Naucratinae. PMID- 29193146 TI - Control networks and hubs. AB - Executive control functions are associated with frontal, parietal, cingulate, and insular brain regions that interact through distributed large-scale networks. Here, we discuss how fMRI functional connectivity can shed light on the organization of control networks and how they interact with other parts of the brain. In the first section of our review, we present convergent evidence from fMRI functional connectivity, activation, and lesion studies that there are multiple dissociable control networks in the brain with distinct functional properties. In the second section, we discuss how graph theoretical concepts can help illuminate the mechanisms by which control networks interact with other brain regions to carry out goal-directed functions, focusing on the role of specialized hub regions for mediating cross-network interactions. Again, we use a combination of functional connectivity, lesion, and task activation studies to bolster this claim. We conclude that a large-scale network perspective provides important neurobiological constraints on the neural underpinnings of executive control, which will guide future basic and translational research into executive function and its disruption in disease.

AB - Differential diagnosis of observed morphological features on an adult male bonobo skeleton was consistent with idiopathic scoliosis. Directional asymmetry was an order of magnitude higher compared with asymptomatic skeletons. This possible case of idiopathic scoliosis contributes to data that suggest a weaker tie between bipedalism and scoliosis than previously hypothesized.

AB - BACKGROUND: Exposure to alcohol content in movies has been shown to be associated with adolescent use of alcohol, including earlier onset. This study examined the influence of movie alcohol exposure on subsequent alcohol onset, considering the social context (whether the movie was viewed with a friend or parent). We examined whether media's influence holds across a spectrum of early drinking milestones: sipping (but not consuming a full drink of) alcohol, consuming a full drink of alcohol, and engaging in heavy episodic drinking (HED). METHODS: Data were taken from a sample of 882 middle school youth (52% female; 24% non-White) enrolled in an ongoing study on alcohol initiation and progression. Exposure to alcohol content in films was measured using a method that combines content analysis and random assignment of movie titles to youth surveys. The hazard of initiating alcohol use (sip, full drink, HED) as a function of exposure was estimated using survival analysis. Associations were adjusted for demographic, personality, and social influence factors known to be associated with both movie exposure and alcohol use. RESULTS: Exposure to alcohol content was common. Hours of exposure prospectively predicted earlier onset of alcohol involvement across all outcomes. Viewing movies with friends appeared to augment the media exposure effect, in contrast to viewing movies with parents, which was not a significant predictor of initiation. CONCLUSIONS: Exposure to alcohol in films is involved in the entry into early stages of alcohol involvement. Findings support further investigation into the role of the media in underage drinking, especially in the context of consuming media with friends and peers. Limiting media exposure and/or stronger Federal Trade Commission oversight of movie ratings should be a priority for preventing underage drinking. PMID- 29193152 TI - The high prevalence of pathogenic Vibrio harveyi with multiple antibiotic resistance in scale drop and muscle necrosis disease of the hybrid grouper, Epinephelus fuscoguttatus (?) * E. lanceolatus (?), in China. AB - Scale drop and muscle necrosis disease with high mortality widely occurred recently in the hybrid grouper (Epinephelus fuscoguttatus ? * E. lanceolatus ?), a crucial cultured marine fish species in China. In this study, 30 Harveyi clade isolates of 27 Vibrio harveyi strains were isolated from diseased hybrid groupers in the south-east and north-east coastal areas of China. A total of 22 V. harveyi strains were determined to be pathogenic, and most challenged fish died within 2 days of infection; surviving individuals exhibited scale drop and deep dermal lesions as naturally diseased fish. Although five typical virulence genes, including luxR, toxRVh , chiA, serine protease and vhh widely existed in V. harveyi, no obvious correlation was established between virulent strains and virulence genes harboured in them. Furthermore, multiple antibiotic resistance was widely exhibited in Harveyi clade strains, particularly for penicillins, polypeptides, lincomycins, acetylspiramycin, streptomycin, metronidazole and bacitracin. And the multiple antibiotic resistance indices were gradually decreased from southern to northern areas of China. This study demonstrated that the pathogenic V. harveyi with multiple antibiotic resistance is highly prevalent in hybrid grouper in China, which requires particular attention. PMID- 29193153 TI - Aquaporin 4 expression in human skeletal muscle fiber types. AB - INTRODUCTION: Aquaporins (AQPs) are a family of transmembrane proteins involved in the maintenance of osmotic gradients. AQP4 is abundant in skeletal muscle, where it seems to be associated with glycolytic metabolism. We investigated the pattern of expression of AQP4 in normal human myofibers relative to the main forms of myosin heavy chain (MHC). METHODS: Six normal human muscle biopsies were analyzed by double immunofluorescence for co-expression of AQP4 and slow or fast MHC. RESULTS: A high percentage (64-99%) of MHC-fast positive fibers showed immunoreaction for AQP4. Immunoreactivity for AQP4 was also present in MHC-slow positive fibers, but with a higher variability (5-72%) among biopsies. DISCUSSION: The expression pattern of AQP4 in human myofibers is highly variable among different patients and cannot be predicted for single fibers depending on MHC type expression. Other factors, possibly related to muscle activity, may modulate AQP4 expression. Muscle Nerve 57: 856-859, 2018. PMID- 29193154 TI - Prevalence and predictors of peripheral neuropathy in nondiabetic children with chronic kidney disease. AB - INTRODUCTION: This study sought to determine the prevalence and predictors of peripheral neuropathy in nondiabetic children with chronic kidney disease (CKD). METHODS: Fifty-one consecutive normally nourished children, 3-18 years of age, with CKD stages IV and V of nondiabetic etiology were enrolled from May to December 2012. Nerve conduction studies were performed in 50 children. Blood samples were analyzed for the biochemical parameters, trace elements, and micronutrients. RESULTS: The prevalence of peripheral neuropathy in our cohort was 52% (95% confidence interval 37.65, 66.34). The majority (80.8%) of the children had axonal neuropathy, and 11.5% had demyelinating neuropathy. Isolated motor neuropathy was identified in 92.3% of the children, and sensorimotor neuropathy was identified in 7.6%. The significant risk factors associated with peripheral neuropathy were older age, low serum copper, and dialysis therapy. DISCUSSION: Electrodiagnostic studies should be performed in children with CKD to assess for peripheral neuropathy for the purpose of optimizing medical care. Muscle Nerve 57: 792-798, 2018.

PMID- 29193156 TI - Validating and implementing the use of an infusion pump for the administration of thawed hematopoietic progenitor cells-a single-institution experience. AB - BACKGROUND: Direct thaw and administration of previously cryopreserved peripheral blood stem cell products is a commonly used practice and should be performed rapidly to reduce cellular damage caused by dimethyl sulfoxide exposure. Cells are typically thawed at the bedside and infused by gravity through a high-flow rate central venous catheter. An existing nontunneled catheter is occasionally used instead and often results in a slower infusion rate. To ensure expedient and consistent infusions, we validated and implemented the use of an infusion pump for thawed peripheral blood stem cells. STUDY DESIGN AND METHODS: Validation was performed in two phases: in vitro simulation and in vivo clinical assessment. Total nucleated cell recovery and viability plus progenitor cell viability and potency were compared in vitro between two cryopreserved peripheral blood stem cell units that were either passed through a preset infusion pump or drained by gravity. The infusion rate, adverse events, and engraftment times were retrospectively compared between patients who received infusions by infusion pump (n = 35) and by gravity (n = 38). RESULTS: No significant differences were observed in vitro between the infusion methods for all measured variables. Overall infusion rates were similar in vivo for both groups but were significantly lower for patients who had nontunneled catheters that delivered the infusion by gravity. The time to neutrophil and platelet engraftment was similar for both groups. CONCLUSION: This is the first study to assess the use of an infusion pump for stem cell transplant. The use of an infusion pump for peripheral blood stem cell infusion is safe, provides a reliable and consistent infusion method, and can mitigate the effect of the type of venous access line used. PMID- 29193157 TI - Aeromonas caviae inhibits hepatic enzymes of the phosphotransfer network in experimentally infected silver catfish: Impairment on bioenergetics. AB - Several studies have been demonstrated that phosphotransfer network, through the adenylate kinase (AK) and pyruvate kinase (PK) activities, allows for new perspectives leading to understanding of disease conditions associated with disturbances in energy metabolism, metabolic monitoring and signalling. In this sense, the aim of this study was to evaluate whether experimental infection by Aeromonas caviae alters hepatic AK and PK activities of silver catfish Rhamdia quelen. Hepatic AK and PK activities decreased in infected animals compared to uninfected animals, as well as the hepatic adenosine triphosphate (ATP) levels. Also, a severe hepatic damage was observed in the infected animals due to the presence of dilation and congestion of vessels, degeneration of hepatocytes and loss of liver parenchyma architecture and sinusoidal structure. Therefore, we have demonstrated, for the first time, that experimental infection by A. caviae inhibits key enzymes linked to the communication between sites of ATP generation and ATP utilization. Moreover, the absence of a reciprocal compensatory mechanism between these enzymes contributes directly to hepatic damage and for a severe energetic imbalance, which may contribute to disease pathophysiology. PMID- 29193158 TI - Terlipressin-induced modifications of Doppler ultrasound signals of systemic arteries in preterm infants with vasoactive-resistant patent ductus arteriosus: A pilot study. AB - PURPOSE: To study the effects of terlipressin (TP) infusion on systemic perfusion, estimated with pulsed-wave Doppler ultrasonography of systemic arteries, in a population of extremely low birth-weight (ELBW) preterm infants with vasoactive-resistant ductus arteriosus. METHODS: This prospective, observational cohort included, during five years, 12 ELBW infants with hemodynamically significant patent ductus arteriosus and absent or reversed diastolic flow at Doppler ultrasonography of systemic arteries, despite treatment and high-dose vasoactive support. We measured flow velocity of the anterior cerebral, right renal, and superior mesenteric arteries before and after TP infusion. Changes were evaluated by Spearman's rho coefficient analysis, Wilcoxon signed-rank, and Friedman test. RESULTS: Time-averaged mean velocity of the renal artery (P = .028) increased, while renal pulsatility (P = .010) and resistance (P = .004) indexes, and cerebral artery resistance index (P = .021) decreased after TP infusion. Time-averaged mean velocity of the anterior cerebral artery proportionately increased with dopamine dose (rho = 0.678; P = .015), but showed opposite shifts after TP (rho = -0.662; P = .024). CONCLUSIONS: These changes suggest that TP may improve systemic perfusion in the ELBW infants with vasoactive-resistant ductus arteriosus. PMID- 29193159 TI - Investigation of the quality of stored red blood cells after simulated air drop in the maritime environment. AB - BACKGROUND: Maritime medical capability may be compromised by blood resupply. Air dropped red blood cells (RBCs) is a possible mitigation factor. This study set out to evaluate RBC storage variables after a simulated parachute air drop into the sea, as limited data exist. STUDY DESIGN AND METHODS: The air load construction for the air drop of blood was subject to static drop assessment to simulate a worst-case parachute drop scenario. One control and two test Golden Hour shipping containers were each packaged with 10 RBC units. The control box was not dropped; Test Boxes 1 and 2 were further reinforced with waterproof boxes and underwent a simulated air drop on Day 7 or Day 8 postdonation, respectively. One day after the drop and once a week thereafter until Day 43 of storage, RBCs from each box were sampled and tested for full blood counts, hemolysis, adenosine triphosphate, 2,3-diphosphoglycerate, pH, extracellular potassium, glucose, lactate, deformability, and RBC microvesicles. RESULTS: The packaging configuration completed the air drop with no water ingress or physical damage. All units met UK specifications for volume, hemoglobin, and hemolysis. There were no significant differences for any of the variables studied between RBCs in the control box compared to RBCs in Test Boxes 1 and 2 combined over storage. CONCLUSION: The test proved that the packaging solution and the impact of a maritime air drop as performed in this study, on Day 7 or Day 8 postdonation, did not affect the in vitro quality of RBCs in SAGM over storage for 35 days. PMID- 29193161 TI - Chlorhexidine. PMID- 29193160 TI - Multicenter Experience With Mechanical Circulatory Support Using a New Diagonal Pump in 233 Children. AB - Technological innovations in pediatric extracorporeal life support circuits can reduce system-related complications and may improve patients' outcome. The Deltastream DP3 (Medos Medizintechnik AG, Stolberg, Germany) is a novel rotational pump with a diagonally streamed impeller that can be used over a broad range of flows. We collected patient data from seven pediatric centers to conduct a retrospective cohort study. We examined 233 patients whose median age was 1.9 (0-201) months. The DP3 system was used for cardiopulmonary support as veno arterial extracorporeal membrane oxygenation (ECMO) in 162 patients. Respiratory support via veno-venous ECMO was provided in 63 patients. The pump was used as a ventricular assist device in eight patients. Median supporting time was 5.5 (0.2 69) days and the weaning rate was 72.5%. The discharge home rate was 62% in the pulmonary group versus 55% in the cardiac group. Extracorporeal cardiopulmonary resuscitation was carried out in 24 patients (10%) with a survival to discharge of rate of 37.5%. About 106 (47%) children experienced no complications, while 33% suffered bleeding requiring blood transfusion or surgical intervention. Three patients suffered a fatal cerebral event. Renal replacement therapy was performed in 28% and pump or oxygenator exchange in 26%. Multivariable analysis identified system exchange (OR 1.94), kidney failure (OR 3.43), and complications on support (OR 2.56) as risk factors for dismal outcome. This novel diagonal pump has demonstrated its efficacy in all kinds of mechanical circulatory and respiratory support, revealing good survival rates. PMID- 29193162 TI - Influence of fertilizers and rice cultivation methods on the abundance and diversity of phyllosphere microbiome. AB - Rice paddies are man-made, cross-over ecologies of aquatic and terrestrial systems, which favor the proliferation of characteristic microbial communities. Moisture regimes under flooded and different levels of irrigation such as in direct seeded rice (DSR) and system of rice intensification (SRI) lead to modulation in crop physiology, soil nutrient availability, and the soil microbiome. However, the diversity of the rice phyllosphere microbiome is less investigated in terms of the influence of fertilizer application and the method of rice cultivation (conventional-flooded, DSR and SRI). Scanning electron micrographs revealed the presence of bacteria as aggregates at microsites of the leaves. Phylogenetic analysis of the dominant culturable bacterial isolates using 16S rDNA sequences revealed that they belonged to the genera - Bacillus, Brevibacillus, Pantoea, Enterobacter, Pseudomonas, Erwinia, and Streptomyces. Fertilizer application brought about a distinct modulation in the communities belonging to phyla such as Bacteriodetes, Firmicutes, and Planctomyces, besides Proteobacteria. The cyanobacterial population was much influenced by the cultivation methods, particularly the SRI. Principal component analysis (PCA), involving the culturable phyllospheric microbial groups and leaf attributes (nutrients and pigments), illustrated the importance of leaf nitrogen and zinc. Also, the communities of the phylum Firmicutes exhibited marked changes in terms of the diversity, not only due to the cultivation method, but also the application of fertilizers. Thus, the cultivation methods and fertilizer application played important roles in modulating both the structural (taxonomical) and functional attributes of the phyllosphere microbiome. PMID- 29193164 TI - Clinical and Supervisory Considerations for Transgender Therapists: Implications for Working with Clients. AB - Transgender therapists have unique and valuable perspectives into how gender organizes the therapeutic process. Currently, in the MFT field, there is discussion of the cisgender therapist's experience in the therapy room, but no known articles on the transgender therapist's experience. This article provides insight into the experiences of transgender therapists around issues of self disclosure, social locations of both therapist and client, and clinical supervision. Drawing from our clinical experiences as transmen, we highlight special considerations for working with cisgender, queer, and transgender clients. Implications for supervision of transgender therapists are also discussed. As more gender diverse students seek MFT training, there is an urgent need to acknowledge their perspectives. This article is a call for beginning conversations in this direction. PMID- 29193163 TI - Production, purification, and characterization of a novel serine-esterase from Aspergillus westerdijkiae. AB - Esterases hydrolyze water soluble short chain fatty acids esters and are biotechnologically important. A strain of Aspergillus westerdijkiae isolated from cooking oil for recycling was found to secrete an esterase. The best enzyme production (19-24 U/ml of filtrate) culture conditions were stablished. The protein was purified using ammonium sulphate precipitation, dialysis, and a chromatographic step in Sephacryl S-200 HR. The 32 kDa purified protein presented an optimal temperature of 40 degrees C, with a T50 of 48.95 degrees C, and an optimal pH of 8.0. KM and Vmax were 638.11 uM for p-NPB and 5.47 umol of released p-NP . min-1 . ug-1 of protein, respectively. The purified enzyme was partially active in the presence of 25% acetone. PMSF inhibited the enzyme, indicating that it is a serine hydrolase. MS enzyme peptides sequences were used to find the protein in the A. westerdijkiae sequenced genome. A structure model demonstrated that the protein is a member of the a/beta -hydrolase fold superfamily. PMID- 29193165 TI - Precise Quantitative Assessment of the Clinical Performances of Two High-Flux Polysulfone Hemodialyzers in Hemodialysis: Validation of a Blood-Based Simple Kinetic Model Versus Direct Dialysis Quantification. AB - Highly permeable dialysis membranes with better design filters have contributed to improved solute removal and dialysis efficacy. However, solute membrane permeability needs to be well controlled to avoid increased loss of albumin that is considered to be detrimental for dialysis patients. A novel high-flux dialyzer type (FX CorDiax; Fresenius Medical Care) incorporating an advanced polysulfone membrane modified with nano-controlled spinning technology to enhance the elimination of a broader spectrum of uremic toxins has been released. The aim of this study was to compare in the clinical setting two dialyzer types having the same surface area, the current (FX dialyzer) and the new dialyzer generation (FX CorDiax), with respect to solute removal capacity over a broad spectrum of markers, including assessment of albumin loss based on a direct dialysis quantification method. We performed a crossover study following an A1-B-A2 design involving 10 patients. Phase A1 was 1 week of thrice-weekly bicarbonate hemodialysis with the FX dialyzer, 4 h per treatment; phase B was performed with a similar treatment regimen but with a new FX CorDiax dialyzer and finally the phase A2 was repeated with FX dialyzer as the former phase. Solute removal markers of interest were assessed from blood samples taken before and after treatment and from total spent dialysate collection (direct dialysis quantification) permitting a mass transfer calculation (mg/session into total spent dialysate/ultrafiltrate). On the blood side, there were no significant differences in the solute percent reduction between FX CorDiax 80 and FX 80. On the dialysate side, no difference was observed regarding eliminated mass of different solutes including beta2 -microglobulin (143.1 +/- 33.6 vs. 138.3 +/- 41.9 mg, P = 0.8), while the solute mass removal of total protein (1.65 +/- 0.51 vs. 2.14 +/- 0.75 g, P = 0.04), and albumin (0.41 +/- 0.21 vs. 1.22 +/- 0.51 g, P < 0.001) were significantly less for FX CorDiax 80 compared to the FX 80 dialyzer. The results of this cross-over study indicate that the new FX CorDiax dialyzer has highly effective removal of middle molecules, without any concomitant increase in total protein and albumin loss. The clinical relevance and potential benefit of this finding needs to be determined. PMID- 29193166 TI - Multiplex identification of sepsis-causing Gram-negative pathogens from the plasma of infected blood. AB - Early and accurate detection of bacterial pathogens in the blood is the most crucial step for sepsis management. Gram-negative bacteria are the most common organisms causing severe sepsis and responsible for high morbidity and mortality. We aimed to develop a method for rapid multiplex identification of clinically important Gram-negative pathogens and also validated whether our system can identify Gram-negative pathogens with the cell-free plasm DNA from infected blood. We designed five MLPA probe sets targeting the genes specific to major Gram-negative pathogens (uidA and lacY for E. coli, ompA for A. baumannii, phoE for K. pneumoniae, and ecfX for P. aeruginosa) and one set targeting the CTX-M group 1 to identify the ESBL producing Gram-negative pathogens. All six target specific peaks were clearly separated without any non-specific peaks in a multiplex reaction condition. The minimum detection limit was 100 fg of pathogen DNA. When we tested 28 Gram-negative clinical isolates, all of them were successfully identified without any non-specific peaks. To evaluate the clinical applicability, we tested seven blood samples from febrile patients. Three blood culture positive cases showed E. coli specific peaks, while no peak was detected in the other four culture negative samples. This technology can be useful for detection of major sepsis-causing, drug-resistant Gram-negative pathogens and also the major ESBL producing Gram-negatives from the blood of sepsis patients in a clinical setting. This system can help early initiation of effective antimicrobial treatment against Gram-negative pathogens for sepsis patients, which is very crucial for better treatment outcomes. PMID- 29193167 TI - Childbearing importance: A qualitative study of women with infertility in China. AB - The primary goal of this study was to examine and describe the importance of childbearing as perceived by infertile women in the Chinese familial and social context. We adopted a qualitative descriptive method and conducted semi structured interviews with female patients diagnosed with infertility. Participants were recruited at a high-volume fertility clinic in Tianjin, China. Fifteen women with a diagnosis of infertility were interviewed for 60-90 min. Data were analyzed by thematic analysis. Two themes supported the importance of childbearing for Chinese women with infertility: childbearing as natural law, and childbearing for relational harmony. Childbearing as natural law referred to intrinsic forces to seek a child, including (i) achieving motherhood and womanhood and (ii) experiencing a developmental transition with childbearing as a landmark. Relational harmony included three primary factors: (i) to maintain marital quality by preventing marital failure and rejuvenating an unsatisfactory marital relationship; (ii) to fulfill both authoritative and reciprocal filial piety; (iii) to build a sense of normalcy within family and social networks. In summary, infertility resulted in loss of motherhood, womanhood, and a smooth developmental transition. Moreover, it threatened relationship harmony in the marriage, family, and social life. These insights on the value of childbearing in the Chinese context can inform healthcare professionals in identify infertility related demands and developing relevant psychosocial services for people with infertility. PMID- 29193168 TI - Energy response corrections for profile measurements using a combination of different detector types. AB - PURPOSE: Different detector properties will heavily affect the results of off axis measurements outside of radiation fields, where a different energy spectrum is encountered. While a diode detector would show a high spatial resolution, it contains high atomic number elements, which lead to perturbations and energy dependent response. An ionization chamber, on the other hand, has a much smaller energy dependence, but shows dose averaging over its larger active volume. We suggest a way to obtain spatial energy response corrections of a detector independent of its volume effect for profiles of arbitrary fields by using a combination of two detectors. METHODS: Measurements were performed at an Elekta Versa HD accelerator equipped with an Agility MLC. Dose profiles of fields between 10 * 4 cm2 and 0.6 * 0.6 cm2 were recorded several times, first with different small-field detectors (unshielded diode 60012 and stereotactic field detector SFD, microDiamond, EDGE, and PinPoint 31006) and then with a larger volume ionization chamber Semiflex 31010 for different photon beam qualities of 6, 10, and 18 MV. Correction factors for the small-field detectors were obtained from the readings of the respective detector and the ionization chamber using a convolution method. Selected profiles were also recorded on film to enable a comparison. RESULTS: After applying the correction factors to the profiles measured with different detectors, agreement between the detectors and with profiles measured on EBT3 film was improved considerably. Differences in the full width half maximum obtained with the detectors and the film typically decreased by a factor of two. Off-axis correction factors outside of a 10 * 1 cm2 field ranged from about 1.3 for the EDGE diode about 10 mm from the field edge to 0.7 for the PinPoint 31006 25 mm from the field edge. The microDiamond required corrections comparable in size to the Si-diodes and even exceeded the values in the tail region of the field. The SFD was found to require the smallest correction. The corrections typically became larger for higher energies and for smaller field sizes. CONCLUSIONS: With a combination of two detectors, experimentally derived correction factors can be obtained. Application of those factors leads to improved agreement between the measured profiles and those recorded on EBT3 film. The results also complement so far only Monte Carlo simulated values for the off-axis response of different detectors.

AB - BACKGROUND: The difficulty of supplying red blood cells within an adequate time to patients undergoing surgery is a known problem for transfusion services, particularly if the operating theater is located at some distance from the blood bank. The consequences frequently are that more blood is ordered than required; several units are allocated and issued; and unused units must be returned to the blood bank. Some sparse reports have demonstrated that remote blood issue systems can improve the efficiency of issuing blood. STUDY DESIGN AND METHODS: This study describes a computer-controlled, self-service, remote blood-release system, combined with an automated refrigerator, installed in a hospital at which major surgery was performed, located 5 kilometers away from the transfusion service. With this system, red blood cell units were electronically allocated to patients immediately before release, when the units actually were needed. Two 2-year periods, before and after implementation of the system, were compared. RESULTS: After implementation of the system, the ratio of red blood cell units returned to the transfusion service was reduced from 48.9% to 1.6% of the issued units (8852 of 18,090 vs. 182 of 11,152 units; p < 0.0001), and the issue-to-transfusion ratio was reduced from 1.96 to 1.02. An increase in the number of transfused red blood cell units was observed, probably mainly due to changes in the number and complexity of surgical procedures. No transfusion errors occurred in the two periods. CONCLUSION: The current results demonstrate that the remote blood release system is safe and useful for improving the efficiency of blood issue for patients in remote operating theatres. PMID- 29193170 TI - Dielectrophoretic choking phenomenon of a deformable particle in a converging diverging microchannel. AB - The translational motion of small particles in an electrokinetic fluid flow through a constriction can be enhanced by an increase of the applied electric potential. Beyond a critical potential, however, the negative dielectrophoresis (DEP) can overpower other forces to prevent particles that are even smaller than the constriction from passing through the constriction. This DEP choking phenomenon was studied previously for rigid particles. Here, the DEP choking phenomenon is revisited for deformable particles, which are ubiquitous in many biomedical applications. Particle deformability is measured by the particle shear modulus, and the choking conditions are reported through a parametric study that includes the channel geometry, external electric potential, and particle zeta potential. The study was carried out using a numerical model based on an arbitrary Lagrangian-Eulerican (ALE) finite-element method. PMID- 29193171 TI - Into the theory of the partial-filling affinity capillary electrophoresis and the determination of apparent stability constants of analyte-ligand complexes. AB - The partial-filling affinity capillary electrophoresis (pf-ACE) works with a ligand present in a background electrolyte that forms a weak complex with an analyte. In contrast to a more popular mobility-shift affinity capillary electrophoresis, only a short plug of the ligand is introduced into a capillary in the pf-ACE. Both methods can serve for determining apparent stability constants of the formed complexes but this task is hindered in the pf-ACE by the fact that the analyte spends only a part of its migration time in a contact with the ligand. In 1998, Amini and Westerlund published a linearization strategy that allows for extracting an effective mobility of an analyte in the presence of a neutral ligand out of the pf-ACE data. The main purpose of this paper is to show that the original formula is only approximate. We derive a new formula and demonstrate its applicability by means of computer simulations. We further inspect several strategies of data processing in the pf-ACE regarding a risk of an error propagation. This establishes a good practice of determining apparent stability constants of analyte-ligand complexes by means of the pf-ACE.

AB - Sensitive and fast detection of ibuprofen enantiomers is very critical for required routine monitoring and risk assessment of trace pollutants in water samples. Here a simple, rapid and highly sensitive android smartphone application for chiral recognition was developed. Aptamer-capped gold nanoparticles (AuNPs) was demonstrated as an efficient detection platform for (S)-(+)-ibuprofen (S-Ibu) and (R)-(-)-ibuprofen (R-Ibu). Detachment of an enantioselective aptamer from the AuNPs surface and binding with an enantiomer of Ibu lead to AuNPs aggregation, which allows a rapid enantiodiscrimination of Ibu by monitoring the absorbance changes of AuNPs solution in the UV-vis spectrum. Under optimal conditions, the limit of detection for S-Ibu and R-Ibu was 1.24 and 3.91 pg/mL, respectively. These probes showed good chiral recognition ability in mixed samples (i.e. S-Ibu + R-Ibu) and environmental samples. These advantages can be further developed by quantitative measurement with smartphone, which opens new opportunities for on site detection of trace chiral pollutants in a simple and practical manner. PMID- 29193173 TI - The fractional laser-induced coagulation zone characterized over time by laser scanning confocal microscopy-A proof of concept study. AB - BACKGROUND: Ablative fractional laser (AFXL) is an acknowledged technique to increase uptake of topical agents in skin. Micro thermal ablation zones (MAZs) consist of ablated vertical channels surrounded by a coagulation zone (CZ). Laser scanning confocal microscopy (LSCM) images individual MAZs at 733 nm (reflectance confocal microscopy (RCM)). Further, LSCM can image sodium fluorescein (NaF) fluorescence with 488 nm excitation (fluorescence confocal microcopy (FCM)), a small hydrophilic test molecule (370 MW, log P -1.52), which may simulate uptake, bio-distribution and kinetics of small hydrophilic drugs. OBJECTIVES: To explore LSCM for combined investigations of CZ thickness and uptake, bio-distribution and kinetics of NaF in AFXL-exposed skin. STUDY DESIGNS/METHODS AND MATERIALS: Excised human abdominal skin samples were exposed to AFXL (15 mJ/microbeam, 2% density) and NaF gel (1000 MUg/ml, 10 MUl/cm2) in six repetitions, including untreated control samples. CZ thickness and spatiotemporal fluorescence intensities (FI) were quantified up to four hours after NaF application by RCM and FCM. Test sites were scanned to a depth of 200 MUm, quantifying thickness of skin compartments (stratum corneum, epidermis, upper dermis), individual CZ thicknesses and FI in CZ and surrounding skin. RESULTS: RCM images established skin morphology to a depth of 200 MUm. The CZ thickness measurements were feasible to a depth of 50 MUm, and remained unchanged over time at 50 MUm (P > 0.5). FI were detected to a depth of 160 MUm and remained constant in CZ up to four hours after NaF application (15 minutes: 79 AU (73-92 AU), 60 minutes: 72 AU (58-82 AU), four hours: 78 AU (71-90 AU), P > 0.1). In surrounding skin, FI increased significantly over time, but remained lower than FI in CZ (15 minutes: 21 AU (17-22 AU), 60 minutes: 21 AU (19-26 AU), four hours: 42 (31- 48 AU), P = 0.03). AFXL-processed skin generated higher FI compared to non-laser processed skin in epidermis and upper dermis at 60 minutes and four hours (P = 0.03). CONCLUSIONS: By LSCM, assessment of the AFXL-induced CZ thickness was feasible to a depth of 50 MUm, and assessment of FI from a small hydrophilic test molecule, NaF in CZ and surrounding skin feasible to a depth of 160 MUm.

AB - : The present study was undertaken to determine the mechanism of antibacterial activity of a polyphenolic fraction, composed of mainly catechin and isorhamnetin, previously isolated from Kombucha, a 14-day fermented beverage of sugared black tea, against the enteropathogen Vibrio cholerae N16961. Bacterial growth was found to be seriously impaired by the polyphenolic fraction in a dose dependent manner. Scanning Electron Microscopy demonstrated morphological alterations in bacterial cells when exposed to the polyphenolic fraction in a concentration-dependent manner. Permeabilization assays confirmed that the fraction disrupted bacterial membrane integrity in both time- and dose-dependent manners, which were proportional to the production of intracellular reactive oxygen species (ROS). Furthermore, each of the polyphenols catechin and isorhamnetin showed the ability to permeate bacterial cell membranes by generating oxidative stress, thereby suggesting their role in the antibacterial potential of Kombucha. Thus, the basic mechanism of antibacterial activity of the Kombucha polyphenolic fraction against V. cholerae involved bacterial membrane permeabilization and morphological changes, which might be due to the generation of intracellular ROS. To the best of our knowledge, this is the first report on the investigation of antibacterial mechanism of Kombucha, which is mostly attributed to its polyphenolic content. SIGNIFICANCE AND IMPACT OF THE STUDY: The emergence of multidrug-resistant Vibrio cholerae strains has hindered an efficient anti-Vibrio therapy. This study has demonstrated the membrane damage mediated antibacterial mechanism of Kombucha, a popular fermented beverage of sugared tea, which is mostly attributed to its polyphenolic content. This study also implies the exploitation of Kombucha as a potential new source of bioactive polyphenols against V. cholerae. PMID- 29193175 TI - Parallel probing of drug uptake of single cancer cells on a microfluidic device. AB - Drug resistance is frequently developing during treatment of cancer patients. Intracellular drug uptake is one of the important characteristics to understand mechanism of drug resistance. However, the heterogeneity of cancer cells requires the investigation of drug uptake at the single cell level. Here, we developed a microfluidic device for parallel probing of drug uptake. We combined a v-type valve and peristaltic pumping to select individual cells from a pool of prostate cancer cells (PC3) and place them successively in separate cell chambers in which they were exposed to the drug. Six different concentrations of doxorubicin, a naturally fluorescent anti-cancer drug, were created in loop-shaped reactors and exposed to the cell in closed 2 nL volume chambers. Monitoring every single cell over time in 18 parallel chambers revealed increased intracellular fluorescence intensity according to the dose of doxorubicin, as well as nuclear localization of the fluorescent drug after 2 h of incubation. The herein proposed technology demonstrated a first series of proof of concept experiments and it shows high potential to use for probing drug sensitivity of single cancer cell. PMID- 29193177 TI - Soft-Bodied Fossils Are Not Simply Rotten Carcasses - Toward a Holistic Understanding of Exceptional Fossil Preservation: Exceptional Fossil Preservation Is Complex and Involves the Interplay of Numerous Biological and Geological Processes. AB - Exceptionally preserved fossils are the product of complex interplays of biological and geological processes including burial, autolysis and microbial decay, authigenic mineralization, diagenesis, metamorphism, and finally weathering and exhumation. Determining which tissues are preserved and how biases affect their preservation pathways is important for interpreting fossils in phylogenetic, ecological, and evolutionary frameworks. Although laboratory decay experiments reveal important aspects of fossilization, applying the results directly to the interpretation of exceptionally preserved fossils may overlook the impact of other key processes that remove or preserve morphological information. Investigations of fossils preserving non-biomineralized tissues suggest that certain structures that are decay resistant (e.g., the notochord) are rarely preserved (even where carbonaceous components survive), and decay prone structures (e.g., nervous systems) can fossilize, albeit rarely. As we review here, decay resistance is an imperfect indicator of fossilization potential, and a suite of biological and geological processes account for the features preserved in exceptional fossils. PMID- 29193176 TI - Using voltage-sensor toxins and their molecular targets to investigate NaV 1.8 gating. AB - Voltage-gated sodium (NaV ) channel gating is a complex phenomenon which involves a distinct contribution of four integral voltage-sensing domains (VSDI, VSDII, VSDIII and VSDIV). Utilizing accrued pharmacological and structural insights, we build on an established chimera approach to introduce animal toxin sensitivity in each VSD of an acceptor channel by transferring in portable S3b-S4 motifs from the four VSDs of a toxin-susceptible donor channel (NaV 1.2). By doing so, we observe that in NaV 1.8, a relatively unexplored channel subtype with distinctly slow gating kinetics, VSDI-III participate in channel opening whereas VSDIV can regulate opening as well as fast inactivation. These results illustrate the effectiveness of a pharmacological approach to investigate the mechanism underlying gating of a mammalian NaV channel complex. PMID- 29193178 TI - Integrated microfluidic biosensing platform for simultaneous confocal microscopy and electrophysiological measurements on bilayer lipid membranes and ion channels. AB - Combining high-resolution imaging and electrophysiological recordings is key for various types of experimentation on lipid bilayers and ion channels. Here, we propose an integrated biosensing platform consisting of a microfluidic cartridge and a dedicated chip-holder to conduct such dual measurements on suspended lipid bilayers, in a user-friendly manner. To illustrate the potential of the integrated platform, we characterize lipid bilayers in terms of thickness and fluidity while simultaneously monitoring single ion channel currents. For that purpose, POPC lipid bilayers are supplemented with a fluorescently-tagged phospholipid (NBD-PE, 1% mol) for Fluorescence Recovery After Photobleaching (FRAP) measurements and a model ion channel (gramicidin, 1 nM). These combined measurements reveal that NBD-PE has no effect on the lipid bilayer thickness while gramicidin induces thinning of the membrane. Furthermore, the presence of gramicidin does not alter the lipid bilayer fluidity. Surprisingly, in lipid bilayers supplemented with both probes, a reduction in gramicidin open probability and lifetime is observed compared to lipid bilayers with gramicidin only, suggesting an influence of NBD-PE on the gramicidin ion function. Altogether, our proposed microfluidic biosensing platform in combination with the herein presented multi-parametric measurement scheme paves the way to explore the interdependent relationship between lipid bilayer properties and ion channel function. PMID- 29193179 TI - Maximum likelihood estimation of influenza vaccine effectiveness against transmission from the household and from the community. AB - Influenza vaccination is recommended as the best way to protect against influenza infection and illness. Due to seasonal changes in influenza virus types and subtypes, a new vaccine must be produced, and vaccine effectiveness (VE) must be estimated, annually. Since 2010, influenza vaccination has been recommended universally in the United States, making randomized clinical trials unethical. Recent studies have used a monitored household cohort study design to determine separate VE estimates against influenza transmission from the household and community. We developed a probability model and accompanying maximum likelihood procedure to estimate vaccine-related protection against transmission of influenza from the household and the community. Using agent-based stochastic simulations, we validated that we can obtain maximum likelihood estimates of transmission parameters and VE close to their true values. Sensitivity analyses to examine the effect of deviations from our assumptions were conducted. We used our method to estimate transmission parameters and VE from data from a monitored household study in Michigan during the 2012-2013 influenza season and were able to detect a significant protective effect of influenza vaccination against community-acquired transmission. PMID- 29193180 TI - Considerations for analysis of time-to-event outcomes measured with error: Bias and correction with SIMEX. AB - For time-to-event outcomes, a rich literature exists on the bias introduced by covariate measurement error in regression models, such as the Cox model, and methods of analysis to address this bias. By comparison, less attention has been given to understanding the impact or addressing errors in the failure time outcome. For many diseases, the timing of an event of interest (such as progression-free survival or time to AIDS progression) can be difficult to assess or reliant on self-report and therefore prone to measurement error. For linear models, it is well known that random errors in the outcome variable do not bias regression estimates. With nonlinear models, however, even random error or misclassification can introduce bias into estimated parameters. We compare the performance of 2 common regression models, the Cox and Weibull models, in the setting of measurement error in the failure time outcome. We introduce an extension of the SIMEX method to correct for bias in hazard ratio estimates from the Cox model and discuss other analysis options to address measurement error in the response. A formula to estimate the bias induced into the hazard ratio by classical measurement error in the event time for a log-linear survival model is presented. Detailed numerical studies are presented to examine the performance of the proposed SIMEX method under varying levels and parametric forms of the error in the outcome. We further illustrate the method with observational data on HIV outcomes from the Vanderbilt Comprehensive Care Clinic. PMID- 29193181 TI - Simultaneous determination of tryptophan, kynurenine, kynurenic acid, xanthurenic acid and 5-hydroxytryptamine in human plasma by LC-MS/MS and its application to acute myocardial infarction monitoring. AB - Reliable methods for the determination of tryptophan and its metabolites are vital to the monitoring of biochemical states during the initiation and progression of cardiovascular disease. In the present study, a single-run liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the simultaneous determination of tryptophan (Trp) and its metabolites, including kynurenine (Kyn), kynurenic acid (KA), xanthurenic acid (XA) and 5 hydroxytryptamine (5-HT), in human plasma. The plasma samples were prepared using a protein precipitation approach, and the chromatographic separation was performed by gradient elution on a C18 column within a total analysis time of 3.5 min. The calibration ranges were 40-20,000 ng/mL for Trp, 4-2000 ng/mL for Kyn, 0.2-100 ng/mL for KA, 0.4-200 ng/mL for XA and 1-500 ng/mL for 5-HT, and the precision and accuracy were acceptable. The evaluation of recovery and internal standard-normalized matrix effect proved that the sample preparation approach was effective and the matrix effect could be negligible. The newly developed method was successfully applied to the analysis of plasma samples from healthy individuals and myocardial infarction patients. The findings suggested that the plasma concentrations of Trp, Kyn, 5-HT as well as the concentration ratios of Kyn/Trp and Trp/5-HT might serve as biomarkers for the monitoring of acute myocardial infarction. PMID- 29193182 TI - Cognitive impairment and quality of life in patients with myotonic dystrophy type 1. AB - INTRODUCTION: This study sought to clarify whether specific cognitive abilities are impaired in patients with myotonic dystrophy type 1 (DM1) as well as to investigate the relationships among quality of life (QoL), cognitive function, and psychological factors. METHODS: Sixty patients with DM1 were evaluated on cognitive functioning (abstract reasoning, attention/working memory, executive function, processing speed, and visuoconstructive ability), apathy, depression, excessive daytime sleepiness, fatigue, and QoL. QoL was assessed by 2 domains of the Muscular Dystrophy Quality of Life Scale (Psychosocial Relationships and Physical Functioning and Health). RESULTS: More than half of the patients exhibited cognitive impairment in attention/working memory, executive function, processing speed, and visuoconstructive ability. The Psychosocial Relationships factor was associated with processing speed, attention/working memory, and apathy, whereas depression and fatigue were associated with 2 QoL domains. DISCUSSION: Our study identified specific cognitive impairments in DM1. Specific cognitive functions and psychological factors may be potential contributors to QoL. Muscle Nerve 57: 742-748, 2018. PMID- 29193183 TI - Microbiological analysis of conjunctival secretion in anophthalmic cavity, contralateral eye and ocular prosthesis of patients with maxillofacial abnormalities. AB - : The purpose of this study was to identify and analyse the micro-organisms present in the conjunctival secretion in anophthalmic cavities of wearers of ocular prostheses, as well as on the prostheses used by them, correlating them with the microbiota of the contralateral eye. Nine patients with maxillofacial abnormalities, wearers of an acrylic resin ocular prosthesis participated in the study. Collections of conjunctival secretions and biofilm were performed on the prosthesis, anophthalmic cavity and contralateral eye for the mycological and bacterial analyses. The data were submitted to statistical analysis, performing a Kendall correlation test to identify the correlation between the collection site and the identified micro-organism (P < 0.05). It was verified that the most prevalent micro-organisms were the Staphylococcus aureus and Staphylococcus epidermidis, independent of the collection site, and that negative cultures for fungi were encountered in 85.2% of collections, independent of the region. It was not possible to establish a correlation among the types of micro-organisms and the collection sites. SIGNIFICANCE AND IMPACT OF THE STUDY: Some evidence suggests that the surface roughness of ocular prostheses can influence interactions with micro-organisms, with greater prejudicial consequences, such as the establishment of biofilms, which could lead to infections. Thus, it becomes extremely important to identify the micro-organisms present on the acrylic surfaces of ocular prostheses, as well as the microbiota of the anophthalmic cavity and contralateral eye of wearers of the same, so that subsequent control measures promote the homeostatic maintenance of the ocular region. PMID- 29193184 TI - Clinical pharmacokinetics of oral drugs in the treatment of multiple myeloma. AB - Treatment of myeloma is a long-term treatment mainly based on all-oral combinations of drugs. Because oral drugs have a more complex pharmacokinetics compared with IV treatments, an appropriate knowledge of the factors that may alter their systemic exposure is of particular clinical relevance. Both drug-drug interactions, food-effect, and dose-adaptation in renal and hepatic impairment may influence the systemic drug levels with a potential impact on drug efficacy or safety. Moreover, a better control of drug exposure may improve the side effect profiles of these treatments with a favourable impact on patient compliance. Furthermore, as long-term treatments, these drugs may also alter the systemic exposure of coadministered medications in these rather old patients. The aim of this review was to identify the factors modifying the systemic exposure of oral drugs used in myeloma by focusing on the pharmacokinetic drug-drug interactions and the effects of renal and hepatic impairment and of food impact. PMID- 29193185 TI - Ketamine Infusion for Adjunct Sedation in Mechanically Ventilated Adults. AB - BACKGROUND: Many critically ill patients receive ketamine for adjunct sedation despite a paucity of evidence on its use, dosing, and monitoring in this setting. OBJECTIVE: To describe the dosing and safety considerations of ketamine for adjunct sedation in a population of mechanically ventilated critically ill patients targeting light sedation. METHODS: We conducted a retrospective review of mechanically ventilated patients receiving continuous ketamine infusion between January 2012 and April 2016. Data included dosing, effect of ketamine on other sedatives, total sedative use, Riker Sedation-Agitation Scale (SAS) scores, adverse drug reactions (ADRs), and hemodynamic variables. RESULTS: Ninety-one patients were included in the analysis. Ketamine was infused at a median dosage of 0.41 mg/kg/hour (range 0.04-2.5 mg/kg/hr) for up to 14.7 days (median 2.8 days). Concomitant sedatives were reduced or discontinued, without the initiation of an additional sedative, in 57 patients (63%) within 24 hours of initiating ketamine. Propofol was most commonly discontinued (16 patients, 36%), followed by benzodiazepines (12 patients, 27%). There was an increase in the number of SAS scores documented in goal in the 24-hour period after ketamine initiation compared with the immediate 24 hours before (61% vs 55%, p=0.001). Patients were less frequently agitated, defined as SAS >4, after the initiation of ketamine (27% vs 33%, p=0.005). Seven patients (7.7%) required discontinuation of ketamine infusion for an ADR. There were no significant changes in hemodynamic variables after the initiation of ketamine. CONCLUSIONS: Continuous ketamine infusion for adjunct light sedation was well tolerated in a cohort of critically ill adults, with an acceptable safety profile. Prospective studies of ketamine infusion are warranted to further establish its efficacy as a sedative in this population. PMID- 29193186 TI - CE-XRF-initial steps toward a non-invasive elemental sensitive detector for liquid separations. AB - The toxicity, bioavailability, and mobilization of elements within the biosphere is dependent on its species. CE has emerged as a strong separation technique for elemental speciation. Conventionally, CE has been coupled with UV-vis, C4 D, PIXE (proton-induced X-ray emission), and ICP-MS. UV-vis and C4 D are not elemental sensitive detection methods, PIXE requires the etching of the detection window resulting in a very brittle capillary, and ICP-MS is an expensive large footprint instrument. Here, we aim to develop an elemental specific detector, XRF (X-ray fluorescence spectrometry), for use with CE. A custom-built micro-XRF was tested and static LODs were determined for 19 elements (Ca-U) with both unmodified (20 926 ppm) and modified capillaries (20-291 ppm). A custom-built CE was combined with the micro-XRF and separation of Ca2+ and Co2+ was obtained. Sr2+ coeluted with Ca2+ in the mixture, but because of the elemental sensitivity of XRF, the Sr and Ca signals could be separated. After successful testing of the micro-XRF, the feasibility of using a low-cost X-ray source and detector was tested. Even lower LODs were obtained for Ga and Rb, showing the feasibility of a smaller, low-cost XRF unit as an elemental specific detector. However, the buffer selection that can be conveniently used with XRF is currently limited due to capillary corrosion, likely correlated to radiolysis. PMID- 29193187 TI - Same-level fall injuries in US workplaces by age group, gender, and industry. AB - BACKGROUND: As the workforce ages, occupational injuries from falls on the same level will increase. Some industries may be more affected than others. METHODS: We conducted a cross-sectional study using data from the Bureau of Labor Statistics to estimate same-level fall injury incidence rates by age group, gender, and industry for four sectors: 1) healthcare and social assistance; 2) manufacturing; 3) retail; and 4) transportation and warehousing. We calculated rate ratios and rate differences by age group and gender. RESULTS: Same-level fall injury incidence rates increase with age in all four sectors. However, patterns of rate ratios and rate differences vary by age group, gender, and industry. Younger workers, men, and manufacturing workers generally have lower rates. CONCLUSIONS: Variation in incidence rates suggests there are unrealized opportunities to prevent same-level fall injuries. Interventions should be evaluated for their effectiveness at reducing injuries, avoiding gender- or age discrimination and improving work ability. PMID- 29193188 TI - Spatially Representing Vulnerability to Extreme Rain Events Using Midwestern Farmers' Objective and Perceived Attributes of Adaptive Capacity. AB - Potential climate-change-related impacts to agriculture in the upper Midwest pose serious economic and ecological risks to the U.S. and the global economy. On a local level, farmers are at the forefront of responding to the impacts of climate change. Hence, it is important to understand how farmers and their farm operations may be more or less vulnerable to changes in the climate. A vulnerability index is a tool commonly used by researchers and practitioners to represent the geographical distribution of vulnerability in response to global change. Most vulnerability assessments measure objective adaptive capacity using secondary data collected by governmental agencies. However, other scholarship on human behavior has noted that sociocultural and cognitive factors, such as risk perceptions and perceived capacity, are consequential for modulating people's actual vulnerability. Thus, traditional assessments can potentially overlook people's subjective perceptions of changes in climate and extreme weather events and the extent to which people feel prepared to take necessary steps to cope with and respond to the negative effects of climate change. This article addresses this knowledge gap by: (1) incorporating perceived adaptive capacity into a vulnerability assessment; (2) using spatial smoothing to aggregate individual level vulnerabilities to the county level; and (3) evaluating the relationships among different dimensions of adaptive capacity to examine whether perceived capacity should be integrated into vulnerability assessments. The result suggests that vulnerability assessments that rely only on objective measures might miss important sociocognitive dimensions of capacity. Vulnerability indices and maps presented in this article can inform engagement strategies for improving environmental sustainability in the region. PMID- 29193190 TI - Indoor allergen levels in settled airborne dust are higher in day-care centers than at home. AB - BACKGROUND: Early-life sensitization to indoor allergens predicts asthma development. The aim of this study was to compare allergen concentrations in day care centers (DCC) with those in private homes. METHODS: Settled airborne dust was collected 4 times a year from 20 German DCC (620 samples) and from the homes of children and day-care workers (602 samples) using electrostatic dust collectors (EDC). The samples were analyzed with fluorescence enzyme immunoassays recognizing domestic mite allergens (DM), Fel d 1, Can f 1, and Mus m 1. Pet allergen thresholds that discriminate samples from homes with cats or dogs from those without were calculated using receiver-operating characteristics. Influences on allergen levels were analyzed using multilevel models. RESULTS: Allergen loads were on average higher in DCC than in homes. In DCC, 96% of the samples were positive for DM, 95% for Can f 1, 90% for Fel d 1, and 83% for Mus m 1. In homes, 84% contained DM, 48.5% Can f 1, 33% Fel d 1, and 43% Mus m 1. The threshold level for homes with dogs was 75 ng/m2 Can f 1 (96.8% sensitivity, 96% specificity), and the threshold level for homes with cats was 46 ng/m2 Fel d 1 (92% sensitivity, 94.9% specificity). In DCC, Can f 1 and Fel d 1 loads were higher than these thresholds in 37% and 54% of the samples, respectively. Allergen levels were significantly influenced by the season and room type; however, carpets on floors had no influence. CONCLUSIONS: Mite, mouse, cat, and dog allergens were mostly higher in DCC than in homes. Exposure to dog and cat allergens in DCC often reached levels of households with pets. PMID- 29193189 TI - Chemical characterization of 21 species of marine macroalgae common in Norwegian waters: benefits of and limitations to their potential use in food and feed. AB - BACKGROUND: In the past few years, much effort has been invested into developing a new blue economy based on harvesting, cultivating and processing marine macroalgae in Norway. Macroalgae have high potential for a wide range of applications, e.g. as source of pharmaceuticals, production of biofuels or as food and feed. However, data on the chemical composition of macroalgae from Norwegian waters are scant. This study was designed to characterize the chemical composition of 21 algal species. Both macro- and micronutrients were analysed. Concentrations of heavy metals and the metalloid arsenic in the algae were also quantified. RESULTS: The results confirm that marine macroalgae contain nutrients which are relevant for both human and animal nutrition, the concentrations whereof are highly dependent on species. Although heavy metals and arsenic were detected in the algae studied, concentrations were mostly below maximum allowed levels set by food and feed legislation in the EU. CONCLUSION: This study provides chemical data on a wide range of algal species covering the three taxonomic groups (brown, red and green algae) and discusses both benefits of and potential limitations to their use for food and feed purposes.

A Risk-Informed Approach to Emergency Response in Oil Terminals. AB - The performance of fire protection measures plays a key role in the prevention and mitigation of fire escalation (fire domino effect) in process plants. In addition to passive and active safety measures, the intervention of firefighting teams can have a great impact on fire propagation. In the present study, we have demonstrated an application of dynamic Bayesian network to modeling and safety assessment of fire domino effect in oil terminals while considering the effect of safety measures in place. The results of the developed dynamic Bayesian network prior and posterior probabilities-have been combined with information theory, in the form of mutual information, to identify optimal firefighting strategies, especially when the number of fire trucks is not sufficient to handle all the vessels in danger. PMID- 29193194 TI - Impact of individual behaviour change on the spread of emerging infectious diseases. AB - Human behaviour plays an important role in the spread of emerging infectious diseases, and understanding the influence of behaviour changes on epidemics can be key to improving control efforts. However, how the dynamics of individual behaviour changes affects the development of emerging infectious disease is a key public health issue. To develop different formula for individual behaviour change and introduce how to embed it into a dynamic model of infectious diseases, we choose A/H1N1 and Ebola as typical examples, combined with the epidemic reported cases and media related news reports. Thus, the logistic model with the health belief model is used to determine behaviour decisions through the health belief model constructs. Furthermore, we propose 4 candidate infectious disease models without and with individual behaviour change and use approximate Bayesian computation based on sequential Monte Carlo method for model selection. The main results indicate that the classical compartment model without behaviour change and the model with average rate of behaviour change depicted by an exponential function could fit the observed data best. The results provide a new way on how to choose an infectious disease model to predict the disease prevalence trend or to evaluate the influence of intervention measures on disease control. However, sensitivity analyses indicate that the accumulated number of hospital notifications and deaths could be largely reduced as the rate of behaviour change increases. Therefore, in terms of mitigating emerging infectious diseases, both media publicity focused on how to guide people's behaviour change and positive responses of individuals are critical.

AB - BACKGROUND: Psoriasis is a common, chronic skin eruption characterized by abnormal hyperproliferation of the epidermis. When assessing psoriasis histologically, it is historically considered a "dry" disease, with significant amounts of serum not expected within lesional stratum corneum. However, this specific feature is not often mentioned within the literature. A retrospective study was undertaken to assess prevalence of serum within stratum corneum in cases of non-palmoplantar psoriasis. METHODS: We evaluated 27 specimens diagnosed histologically as psoriasis between January 2015 and June 2016. In addition to serum, we assessed for psoriasiform hyperplasia, hypogranulosis, suprapapillary thinning and parakeratosis with neutrophils. The cases were then categorized as either diagnostic for, or consistent with, psoriasis and were followed up with clinicians to assess whether the clinical course was consistent with psoriasis. RESULTS: A total of 27 hematoxylin and eosin (H&E)-stained biopsies were examined from 21 patients, with periodic acid-Schiff (PAS) performed on 20 of the biopsies. Of these, 12 biopsies had serum present (44.4%). Of the 12 lesions considered to clinically and histologically represent psoriasis, 5 (41.7%) had serum. CONCLUSION: Our results suggest serum within stratum corneum is possibly an acceptable feature within the spectrum of psoriasis histopathology and should not necessarily detract from the diagnosis. PMID- 29193196 TI - Extracranial and Intracranial Ultrasonographic Findings in Posterior Circulation Infarction. AB - OBJECTIVES: Patients with posterior circulation infarction are at higher risk of early recurrent stroke, especially those with vertebrobasilar stenosis or hypoplasia. The clinical presentations of this condition vary over a broad range, making diagnosis and treatment a challenge. Hemodynamic changes and stenosis detected by ultrasonography (US) are sensitive and important indicators for further evaluation. In this study, we correlated extracranial and intracranial US characteristics with brain magnetic resonance imaging (MRI) in patients with posterior circulation infarction. METHODS: Inpatients with acute ischemic stroke who received both MRI and US were enrolled. Baseline characters, underlying disorders, the ischemic territory, and vascular stenosis on MRI were recorded. Series of US data, including flow volume, diameter, mean velocity, and pulsatility index, were analyzed. Patients with new infarction over the medulla, pons, midbrain, or cerebellum were enrolled as the posterior circulation infarction group. Patients with pure anterior circulation infarction were also enrolled. RESULTS: A total of 210 patients with anterior circulation infarction (mean age +/- SD, 66.24 +/- 12.88 years) and 143 with posterior circulation infarction (mean age, 65.82 +/- 11.39 years) were enrolled. Significant higher frequencies of vertebral artery hypoplasia and decreased intracranial vertebrobasilar velocity in the posterior circulation infarction group (44.75% and 64.33%, respectively) were documented (P < .0001; P = .035). Ischemic lesion distributions were correlated with vertebral artery hypoplasia (55.56 %) and low vertebral and basilar artery velocities (44.44% and 25.53%), as documented by US. A low vertebrobasilar velocity was highly correlated with MRI-documented vascular stenosis (53.06%). CONCLUSIONS: Vertebral artery hypoplasia and a low velocity in the intracranial vertebrobasilar system on US might change the treatment of patients with posterior circulation infarction for primary and secondary prevention. PMID- 29193197 TI - Signalling Profiles of Blood Leucocytes in Sepsis and in Acute Pancreatitis in Relation to Disease Severity. AB - Intracellular signalling in blood leucocytes shows multiple aberrations in acute pancreatitis (AP) complicated by organ dysfunction (OD). We studied whether the aberrations associate with severity of AP and occur in sepsis complicated by OD. The study comprises 14 sepsis patients (11 with shock), 18 AP patients (nine mild; six moderately severe; three severe) and 28 healthy volunteers. Within 48 h after admission to hospital, phosphorylation of nuclear factor-KB (NF-KB), signal transducers and activators of transcription (STATs) 1,3, and extracellular signal regulated kinases 1/2 were measured from stimulated or non-stimulated leucocytes using phosphospecific whole blood flow cytometry. In sepsis, as compared with healthy subjects, phosphorylated NF-KB levels of monocytes promoted by bacterial lipopolysaccharides, tumour necrosis factor or Escherichia coli cells were lower (P < 0.001 for all), pSTAT1 levels of monocytes promoted by IL-6 were lower (P < 0.05 for all), and STAT3 was constitutively phosphorylated in monocytes, neutrophils and lymphocytes (P < 0.001 for all). In AP, severity was associated with proportions of pSTAT1-positive monocytes and lymphocytes promoted by IL-6 (P < 0.01 for both), constitutive STAT3 phosphorylation in neutrophils (P < 0.05), but not with any of the pNF-KB levels. Monocyte pSTAT3 fluorescence intensity, promoted by IL-6, was lower in sepsis and AP patients with OD than in AP patients without OD (P < 0.001). Collectively, signalling aberrations in sepsis with OD mimic those described previously in AP with OD. Possibility that aberrations in STAT1 and STAT3 pathways provide novel markers predicting evolution of OD warrants studies including patients presenting without OD but developing it during follow-up. PMID- 29193198 TI - The DNA-methyltransferase inhibitor 5-aza-2-deoxycytidine affects Humicola grisea enzyme activities and the glucose-mediated gene repression. AB - Humicola grisea var. thermoidea (Hgvt) is a thermophilic ascomycete that produces lignocellulolytic enzymes and it is proposed for the conversion of agricultural residues into useful byproducts. Drugs that inhibit the DNA methyltransferases (DNMTs) activity are employed in epigenetic studies but nothing is known about a possible effect on the production of fungal enzymes. We evaluated the effect of 5 aza-2'-deoxycytidine (5-Aza; a chemical inhibitor of DNMTs activity) on the secreted enzyme activity and on the transcription of cellulase and xylanase genes from Hgvt grown in agricultural residues and in glucose. Upon cultivation on wheat bran (WB), the drug provoked an increase in the xylanase activity at 96 h. When Hgvt was grown in glucose (GLU), a repressor of Hgvt glycosyl hydrolase genes, 5-Aza led to increased transcript accumulation for the cellobiohydrolases and for the xyn2 xylanase genes. In WB, 5-Aza enhanced the expression of the transcription factor CreA gene. Growth on WB or GLU, in presence of 5-Aza, led to a significant increase in transcripts of the pH-response regulator PacC gene. To our knowledge, this is the first report on the effect of a DNMT inhibitor in the production of fungal plant cell wall degradation enzymes. PMID- 29193199 TI - MUC1- and Survivin-based DNA Vaccine Combining Immunoadjuvants CpG and interleukin-2 in a Bicistronic Expression Plasmid Generates Specific Immune Responses and Antitumour Effects in a Murine Colorectal Carcinoma Model. AB - DNA vaccination is a promising cancer treatment due to its safety, but poor immunogenicity limits its application. However, immunoadjuvants, heterogeneous prime-boost strategies and combination with conventional treatments can be used to improve the antitumour immune effects. A CpG motif and interleukin-2 (IL-2) cytokine are often used as adjuvants. In this study, a DNA vaccine containing a CpG motif was constructed to evaluate its adjuvant effect. The results show that the cytotoxicity of the DNA vaccine was increased fivefold, and survival lifetime was prolonged twofold by the CpG motif adjuvant. To simplify the industrial production process, a bicistronic plasmid was constructed to carry the fusion genes of survivin/MUC1 (MS) and IL-2 and with a CpG motif in its backbone. The results showed that the antitumour effect of the bicistronic vaccine was the same as that of the two vaccine co-injected regime. Furthermore, the vaccine could suppress metastatic tumour foci by 69.1% in colorectal carcinoma-bearing mice. Moreover, the vaccine induced survivin- and MUC1-specific immune responses in splenocytes and induced the immune promoting factor CCL-19 and GM-CSF upregulated, while metastatic-associated factor MMP-9 and immunosuppressing factor PD-L1 downregulated in tumour tissue. When combining the vaccine with the chemotherapy drug oxaliplatin, the survival was prolonged by about 2.5-fold. In conclusion, the DNA vaccine containing a CpG motif in bicistronic form showed good effects on colorectal cancer by inhibiting both tumour growth and metastasis, and combination with oxaliplatin could improve its antitumour effects. PMID- 29193200 TI - Rapid identification of microorganisms from platelet concentrates by matrix assisted laser desorption ionization time-of-flight mass spectrometry after short term incubation on liquid medium. AB - BACKGROUND: Platelets (PLTs) are especially affected by the risk of bacterial contamination. Matrix-assisted laser desorption ionization time-of-flight (MALDI TOF) is an accurate method for the routine identification of bacterial isolates in microbiology laboratories. We directly applied the MALDI-TOF method to bacterial detection in PLTs. In this study, we evaluated the sensitivity, specificity, and speed of a direct MALDI-TOF approach compared to the conventional method BACTEC. STUDY DESIGN AND METHODS: Eight bacteria associated with PLT contamination, cited by the ISBT on transfusion-transmitted infectious diseases, were spiked into PLTs for a final concentration of approximately 100 CFU/bag (n = 5 for each strain). The PLTs were then agitated for 24 hours. One milliliter of PLTs was incubated in a shaker incubator for 8 hours at 37 degrees C with 1 mL of trypticase soy broth (TSB). The spectra were analyzed using the MALDI Biotyper software. As a control, 8 mL of PLTs incubated into BACTEC bottles and a positive bottle were subcultured to ensure identification of bacterial growth. RESULTS: Regardless of the strain of PLTs tested, MALDI-TOF analysis made detection and early identification possible at 8 hours. Analysis by BACTEC of PLTs infected with Escherichia coli, Bacillus cereus, and Providencia stuartii made early identification possible. For the remaining bacteria, the detection time by BACTEC was significantly longer than 8 hours. CONCLUSION: We demonstrated the possibility of detecting bacteria in PLTs using a standardized culture step in TSB with MALDI-TOF, regardless of the strain, with the same specificity and analytical sensitivity and with a time to results of 12 hours. This direct method presented rapid and reliable results. PMID- 29193201 TI - Red tattoo-related mycosis fungoides-like CD8+ pseudolymphoma. AB - Cutaneous reactions to red tattoo pigment rarely manifest as pseudolymphomatous reactions. We describe an exceedingly rare case of red tattoo-related T-cell predominant pseudolymphoma microscopically mimicking mycosis fungoides. Careful clinicopathological correlation was required to obtain the correct diagnosis and aid in an effective treatment course. PMID- 29193202 TI - Multifunctional in vivo imaging for monitoring wound healing using swept-source polarization-sensitive optical coherence tomography. AB - BACKGROUND AND OBJECTIVE: Wound healing involves a complex and dynamic biological process in response to tissue injury. Monitoring of the cascade of cellular events is useful for wound management and treatment. The aim of this study is to demonstrate the potential of multifunctional polarization-sensitive optical coherence tomography (PS-OCT) to longitudinally monitor the self-healing process in a murine cutaneous wound model. MATERIALS AND METHODS: A multi-functional PS OCT system based on swept source OCT configuration (1,310 nm central wavelength) was designed to obtain simultaneously microstructural, blood perfusion, and birefringent information of a biological tissue in vivo. A 1-mm-diameter wound was generated in a mouse pinna with a complete biopsy punch. Afterwards, the self healing process of the injured tissue was observed every week over 6-week period using the multifunctional system to measure changes in the tissue birefringence. Further OCT angiography (OCTA) was used in post data processing to obtain blood perfusion information over the injured tissue. RESULTS: Three complementary images indicating the changes in anatomical, vascular, and birefringent information of tissue around wound were simultaneously provided from a 3 dimensional (3-D) PS-OCT data set during the wound repair over 1 month. Specifically, inflammatory and proliferative phases of wound healing were characterized by thickened epidermal tissue (from OCT images) and angiogenesis (from OCT angiography images) around wound. Also, it was observed that the regenerating tissues had highly realigned birefringent structures (from PS-OCT images). CONCLUSION: This preliminary study suggests that the proposed multi functional imaging modality has a great potential to improve the understanding of wound healing through non-invasive, serial monitoring of vascular and tissue responses to injury.

AB - BACKGROUND: Interpretation of Clark's nevi has generated debate over the years; although criteria have been proposed for grading morphological features of melanocytes, there is still confusion and variability in the assessment of these lesions. METHODS: This is a retrospective observational study conducted on 100 Clark's nevi and 84 melanomas. A single expert dermatopathologist evaluated all blinded and randomized photomicrographs of both the Clark's nevi and melanomas for the presence of 14 cytologic features. Subsequently, a multivariate model was used to obtain sensitivity and specificity. RESULTS: Clark's nevi showed a significantly higher frequency of absent-or-inconspicuous nucleoli over melanoma, whereas mitotic figures, pleomorphism, notching, multiple nucleoli, peppered moth nuclear pattern, flattened adjacent nuclei, prominent nucleoli and vesicular nucleus with rounded nucleoli were found significantly higher in frequency in melanomas. CONCLUSION: Our data suggest that nuclear alterations are of value in the differentiation of atypical nevi from melanoma.

AB - INTRODUCTION: Agrin is essential for the formation and maintenance of neuromuscular junctions (NMJs). NT-1654 is a C-terminal fragment of mouse neural agrin. In this study, we determined the effects of NT-1654 on the severity of experimental autoimmune myasthenia gravis (EAMG). METHODS: EAMG was induced in female Lewis rats by immunization with the Torpedo acetylcholine receptor (tAChR) and complete Freund's adjuvant (CFA). NT-1654 was dissolved in phosphate-buffered saline (PBS) and injected daily subcutaneously into tAChR immunized rats during the first 10 days after immunization, and then every other day for the following 20 days. RESULTS: We showed that NT-1654 attenuated clinical severity, effectively promoted the clustering of AChRs at NMJs, and alleviated the impairment of NMJ transmission and the reduction of muscle-specific kinase (MuSK) in EAMG rats. DISCUSSION: We demonstrated that NT-1654 attenuated clinical severity, effectively promoted the clustering of AChRs at NMJs, and alleviated the impairment of NMJ transmission and the reduction of muscle-specific kinase (MuSK) in EAMG rats.

AB - AIMS: Organising pneumonia (OP) is composed of loose granulation tissue plugs in distal airspaces; these disappear with steroid treatment. Recently a variant labelled 'cicatricial' OP has been described in which the granulation tissue organised to much denser fibrous tissue but still retained the usual pattern of OP. Here we report 10 patients thought to have an interstitial lung disease, and who on biopsy had a variant of cicatricial OP characterised by linear bands or small nodular masses of dense fibrous tissue that does not resemble ordinary OP. METHODS AND RESULTS: The bands/nodules were usually distributed randomly but occasionally resembled fibrotic non-specific interstitial pneumonia in local areas. Small foci of loose granulation tissue at the edge of the fibrotic bands sometimes mimicked fibroblast foci. Recognisable conventional OP was always present, but often in very small amounts. Four cases, including one patient with Ehlers-Danlos syndrome, showed formation of bone in the fibrotic bands and nodules. On computerised tomography (CT) scan of the chest some cases looked like typical OP, but some demonstrated only irregularly distributed linear opacities, sometimes with associated calcification. Follow-up imaging on six cases showed that the process either markedly improved or remained stable over time; no case had progressive disease. CONCLUSIONS: Cicatricial OP with this pathological pattern represents an uncommon form of OP that appears to be a generally benign process which may have persisting linear opacities on CT scan but that does not progress; however, it can be confused on biopsy and CT with a fibrosing interstitial pneumonia. PMID- 29193208 TI - Granular cell basal cell carcinoma: A case report. AB - Granular cell basal cell carcinoma (BCC) is a rare histopathological variant of BCC. Our review of the literature revealed only 17 previously identified cases. We report the case of a 47-year-old man who presented with an ulceration on his right upper lip which was subsequently removed. Histopathologic examination revealed that the tumor was composed solely of granular cells with numerous cytoplasmic eosinophilic round inclusion bodies. Mitotic figures ranged from 8 to 15 per 10 high-power fields, with a Ki-67 proliferative index of ~5%. Immunohistochemically, the granular cells showed strong and diffuse positivity for Ber-EP4, pan-cytokeratin, AE1/AE3, CK5/6 and p63 and focal positivity for lysozyme, CD68 (clone KP1) and Bcl-2. PMID- 29193210 TI - What is the value of Values Based Recruitment for nurse education programmes? AB - AIM: A discussion of issues associated with Values Based Recruitment (VBR) for nurse education programmes. BACKGROUND: Values Based Recruitment is a mandatory element in selection processes of students for Higher Education healthcare courses in England, including all programmes across nursing. Students are selected on the basis that their individual values align with those presented in the Constitution of the National Health Service. However, there are issues associated with the use of values as selection criteria that have been insufficiently addressed. These are discussed. DESIGN: Discussion paper. DATA SOURCES: This article is based on documents published on the website of the executive body responsible for the implementation of a policy regarding VBR in Higher Education Institutions up until June 2017 and our evaluation of the conceptualisation of VBR, underpinned by contemporary theory and literature. IMPLICATIONS FOR NURSING: Values Based Recruitment influences who is accepted onto a nurse education programme, but there has been limited critical evaluation regarding the effectiveness of employing values as selection criteria. Values are subject to interpretation and evidence regarding whether or how VBR will improve practice and care is lacking. The issues discussed in this article show that Higher Education Institutions offering nursing courses, whether in England or in other countries, should be critical and reflective regarding the implementation of VBR methods. CONCLUSION: We call for a debate regarding the meaning and implications of VBR and further research regarding its validity and effectiveness. PMID- 29193212 TI - Meta-analysis for the comparison of two diagnostic tests-A new approach based on copulas. AB - Meta-analysis of diagnostic studies is still field of ongoing biometrical research. Especially, clinical researchers call for methods that allow for a comparison of different diagnostic tests to a common gold standard. Focussing on two diagnostic tests, the main parameters of interest are differences of sensitivities and specificities (with their corresponding confidence intervals) between the two diagnostic tests while accounting for the various associations across the two tests and the single studies. Similar to our previous work using generalized linear mixed models to this task, we propose a model with a quadrivariate response consisting of the two sensitivities and the two specificities of both tests. This new approach uses the ideas of copula modelling, and especially a quadrivariate Gaussian copula and a quadrivariate vine copula, which is built from bivariate Plackett copulas. The different copulas are compared in a simulation study and illustrated by the application of population-based screening for type 2 diabetes. PMID- 29193211 TI - Is tranexamic acid exposure related to blood loss in hip arthroplasty? A pharmacokinetic-pharmacodynamic study. AB - AIMS: Tranexamic acid (TXA) is an antifibrinolytic agent, decreasing blood loss in hip arthroplasty. The present study investigated the relationship between TXA exposure markers, including the time above the in vitro threshold reported for inhibition of fibrinolysis (10 mg l-1 ), and perioperative blood loss. METHODS: Data were obtained from a prospective, double-blind, parallel-arm, randomized superiority study in hip arthroplasty. Patients received a preoperative intravenous bolus of TXA 1 g followed by a continuous infusion of either TXA 1 g or placebo over 8 h. A population pharmacokinetic study was conducted to quantify TXA exposure. RESULTS: In total, 827 TXA plasma concentrations were measured in 166 patients. A two-compartment model fitted the data best, total body weight determining interpatient variability in the central volume of distribution. Creatinine clearance accounted for interpatient variability in clearance. At the end of surgery, all patients had TXA concentrations above the therapeutic target of 10 mg l-1 . The model-estimated time during which the TXA concentration was above 10 mg l-1 ranged from 3.3 h to 16.3 h. No relationship was found between blood loss and either the time during which the TXA concentration exceeded 10 mg l-1 or the other exposure markers tested (maximum plasma concentration, area under the concentration-time curve). CONCLUSION: In hip arthroplasty, TXA plasma concentrations were maintained above 10 mg l-1 during surgery and for a minimum of 3 h with a preoperative TXA dose of 1 g. Keeping TXA concentrations above this threshold up to 16 h conferred no advantage with regard to blood loss. PMID- 29193214 TI - In Grateful Recognition of Our Editorial Board. PMID- 29193213 TI - First evidence of viral and bacterial oyster pathogens in the Brazilian coast. PMID- 29193216 TI - In pursuit of peak animal welfare; the need to prioritize the meaningful over the measurable. AB - Despite the diversity of animal welfare definitions, most recognise the centrality of the feelings of animals which are currently impossible to measure directly. As a result, animal welfare assessment is heavily reliant upon the indirect measurement of factors that either affect what animals feel, or are effected by how they feel. Physiological and health orientated measures have emerged as popular metrics for assessing welfare because they are quantifiable, can effect and be affected by how animals feel and have merits regardless of their relationship to the feelings of animals. However, their popularity in animal welfare assessment has led to them having a disproportionate influence on animal management to the detriment of animal welfare in numerous instances. Here, the case is made that a tension exists between management that prioritizes aspects of care reflecting popular animal welfare metrics such as those relating to physical health, and management that emphasizes psychological wellbeing. By re examining the relative merits of physical and psychological priorities in animal management, an alternate animal welfare paradigm emerges less tied to traditional welfare metrics. This paradigm theorizes about the possibility for an optimal animal welfare state to exist where managed animal populations provided essential psychological outlets but protected from key physical stressors routinely experienced in the wild, might experience higher levels of welfare than wild populations would routinely experience. The proposition that optimal animal welfare could theoretically be achieved in well managed and well designed captive environments challenges a widely held ethical perspective that captivity is inherently bad for animal welfare. PMID- 29193217 TI - Reversibility of atrophic gastritis and intestinal metaplasia after Helicobacter pylori eradication - a prospective study for up to 10 years. AB - BACKGROUND: Atrophic gastritis and intestinal metaplasia are premalignant conditions for gastric cancer. Their reversibility by Helicobacter pylori eradication remains controversial. AIM: To evaluate the reversibility of atrophic gastritis and intestinal metaplasia by H. pylori eradication with long-term follow-up. METHODS: 598 subjects were prospectively enrolled and followed for up to 10 years. They were categorised as H. pylori-negative (n = 65), H. pylori non eradicated (n = 91), and H. pylori-eradicated (n = 442). Histological assessment was performed for antrum and corpus by Sydney classification. RESULTS: Histological follow-up was performed regularly at 1, 2, 3-4 and >=5 years, with mean follow-up of 1.07 +/- 0.21, 2.29 +/- 0.83, 3.93 +/- 1.02, and 6.45 +/- 1.28 years, respectively. Atrophic gastritis in antrum and corpus gradually and significantly (both P < .05 for all timepoints) improved only in the H. pylori eradicated group compared to that at baseline. Significant difference in atrophic gastritis between H. pylori-eradicated and H. pylori-negative groups disappeared from 1-year follow-up. Similarly, intestinal metaplasia in antrum and corpus improved significantly (both P < .05 for all timepoints) only in the H. pylori eradicated group in comparison with that at baseline. Significant difference in intestinal metaplasia between H. pylori-eradicated and H. pylori-negative groups disappeared from >=5 years of follow-up in the antrum and from 3 years of follow up in the corpus. CONCLUSION: H. pylori eradication may be a preventative strategy for intestinal-type gastric cancer by regression of atrophic gastritis and intestinal metaplasia.

PMID- 29193219 TI - Therapeutic leukocytapheresis in infants and children with leukemia and hyperleukocytosis: A single institution experience. AB - BACKGROUND: Hyperleukocytosis, defined as white blood cell (WBC) count above 100 * 109 /L, has high early morbidity and mortality from leukostasis-related complications, namely intracranial hemorrhage and pulmonary distress. Initiating chemotherapy without prior leukocytoreduction may lead to tumor lysis syndrome (TLS). Therapeutic leukocytapheresis (TL) is used as one leukocytoreductive intervention; however, its safety and efficacy in pediatric leukemia has not been established. The purpose of this study is to evaluate safety of TL in pediatric patients and assess the efficacy of TL in reducing WBC count in pediatric leukemia. METHODS: Retrospective chart review was conducted on 14 patients with acute lymphoblastic leukemia (ALL) and 5 with acute myeloid leukemia (AML) who underwent TL during the period 2000-2014 at a single institution. RESULTS: Mean WBC count of 19 patients who received TL was 483.2 * 109 /L (547.1 in ALL, 304.3 in AML); a portion of patients presented with central nervous system symptoms (15%), respiratory symptoms (10%), or both (10%). TL reduced WBC count (mean 50.7% reduction after a single TL procedure; additional 17.1% reduction after a second TL procedure in 6 patients). Short-term survival immediately following TL was 100% without any major procedural complication. Mean survival time in patients with AML was 1.5 years and with ALL was 6.5 years. CONCLUSIONS: TL significantly reduces WBC number in pediatric leukemia patients as young as 22 days old. In our retrospective study, TL was not associated with any significant complications and suggests that TL is a safe initial procedure in pediatric leukemia.

Concluding remarks 72 Acknowledgements 72 References 72 SUMMARY: The view that ectomycorrhizal (ECM) fungi commonly participate in the enzymatic liberation of nitrogen (N) from soil organic matter (SOM) has recently been invoked as a key mechanism governing the biogeochemical cycles of forest ecosystems. Here, we provide evidence that not all evolutionary lineages of ECM have retained the genetic potential to produce extracellular enzymes that degrade SOM, calling into question the ubiquity of the proposed mechanism. Further, we discuss several untested conditions that must be empirically validated before it is certain that any lineage of ECM fungi actively expresses extracellular enzymes in order to degrade SOM and transfer N contained therein to its host plant.

AB - AIMS: Mutations in FGFR3 and the promoter region of the telomerase reverse transcriptase (TERT) gene have been found frequently in urothelial carcinoma of the urinary bladder. However, related data for papillary urothelial neoplasm of low malignant potential (PUNLMP) are limited. In this study, we investigated the mutation status of the TERT promoter, FGFR3 and HRAS in low-grade papillary urothelial neoplasms and evaluated their prognostic significance. METHODS AND RESULTS: The cases included in this study comprised 21 inverted papillomas, 30 PUNLMPs and 34 low-grade non-invasive papillary urothelial carcinomas (NIPUCs). TERT promoter mutations were observed in 10 (33%) PUNLMPs and 17 (50%) low-grade NIPUCs, but not in any inverted papilloma. FGFR3 mutations were observed more frequently in PUNLMP and low-grade NIPUC than in inverted papillomas (P = 0.009), whereas the opposite trend was noted for HRAS mutations (P < 0.001). Regarding the clinical outcome, TERT promoter mutation was associated with a higher recurrence rate in PUNLMP (P = 0.024) but not in low-grade NIPUC (P = 0.530). Notably, PUNLMP cases with TERT promoter mutations had a similar recurrence rate to that in low-grade NIPUC cases (P = 0.487). CONCLUSIONS: Our results suggest that the status of the TERT promoter mutation may serve as a biomarker of prognostic stratification in patients with PUNLMP. PMID- 29193226 TI - Generic daclatasvir plus sofosbuvir, with or without ribavirin, in treatment of chronic hepatitis C: real-world results from 18 378 patients in Egypt. AB - BACKGROUND: Treatment of chronic hepatitis C using combination of sofosbuvir (SOF) and daclatasvir (DCV) was used in several clinical trials and multicentre studies, which were somewhat limited to genotypes 1-3. The national program in Egypt is using SOF-DCV combination for large scale treatment. AIM: To assess the efficacy and safety of combined SOF-DCV in treating patients with HCV-G4 in a real-world setting. METHODS: Data and outcome of chronic HCV patients who were treated for 12 weeks with generic medications: DCV 60 mg plus SOF 400 mg +/- ribavirin (RBV) within the national hepatitis C treatment program in Egypt are presented. Treatment-naive patients without cirrhosis were treated without RBV, and those who had cirrhosis or were treatment-experienced (interferon experienced or SOF experienced) received RBV. Efficacy and safety were assessed, and baseline factors associated with sustained virological response at post-treatment week 12 (SVR12) were explored. RESULTS: During the first 2 months of the programme, 18 378 patients with HCV-G4 started treatment with SOF-DCV with or without RBV. Overall, 95.1% achieved SVR12 (95.4% among patients treated without RBV and 94.7% for patients treated with RBV, P = .32). Treatment was prematurely discontinued in only 1.5% of patients. The most common events leading to discontinuation were patient withdrawal (n = 76) and pregnancy (n = 5). Five deaths occurred within this group. CONCLUSIONS: Real-world experience of generic SOF-DCV in patients with chronic HCV-G4 proved to be safe and associated with a high SVR12 rate, in patients with different stages of fibrosis.

AB - OBJECTIVE: To describe a novel Sacroiliac Luxation Instrument System (SILISTM) and its application in minimally invasive osteosynthesis (MIO) of sacroiliac luxations/fractures (SIL/F). The SILIS was designed to provide stable SIL/F reduction and accurate sacral screw placement while reducing personnel exposure to ionizing radiation during intraoperative fluoroscopy. STUDY DESIGN: Descriptive, proof of concept cadaveric study. METHODS: A right SIL and a left SIL/F were created on a Labrador Retriever that had died of natural causes. Bilateral sacroiliac lag screw fixation was performed under fluoroscopic guidance with the SILIS, which consists of dedicated reduction and fixation instruments rigidly linked to table-bound 6-axis arms. RESULTS: Throughout surgery, the SILIS facilitated and maintained stable reduction and allowed accurate placement of a custom designed drill guide over the sacral body without the surgeon's manual holding of any reduction or fixation instruments. The surgical team was therefore able to step away from the C-arm when acquiring fluoroscopic images, thus reducing exposure to radiation. Dorsoventral and craniocaudal screw deviation from an ideal trajectory ranged from 0.9 degrees to 3.8 degrees . Both screws were fully located within the sacral body. CONCLUSION: The SILIS addresses limitations associated with MIO of SIL/F, including maintenance of reduction throughout surgery along with reliable and accurate sacral screw placement. Distance from the X-ray source is the most effective protection against radiation. Use of the SILIS allows the surgical team to move away from the C-arm during fluoroscopy, thereby reducing personnel exposure to dangerous direct and back-scattered ionizing radiation.

PMID- 29193229 TI - Identification of microRNAs and genes associated with hyperandrogenism in the follicular fluid of women with polycystic ovary syndrome. AB - Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disease, which is characterized by hyperandrogenism (HA), chronic anovulation, polycystic ovaries, insulin resistance, and obesity. At present, the mechanism by which PCOS/HA occurs has not been fully elucidated, thus, the mechanisms behind and interventions for HA in PCOS are current hot topics in research. MiRNAs have recently been shown to serve as diagnostic or prognostic biomarkers in patients with cancer. Thus, we are currently focused on studying the altered expression of miRNAs in follicular fluid and their correlation with HA in PCOS. Illumina deep sequencing technology was used to explore different miRNAs in the follicular fluid of women with PCOS/HA and in the follicular fluid of women in a control group. Target prediction databases were then used to analyse the target genes of different expressed miRNAs, and GO analysis and the KEGG pathway database were used to identify the functions and the main biochemical and signalling pathways of differentially expressed target genes. The expression levels of 263 miRNAs were significantly different (>2-fold up-regulated or <0.5-fold down-regulated, P < 0.05) between the two groups of women. For example, the expression levels of miRNA (200a-3p, 10b-3p, 200b-3p, 29c-3p, 99a-3p, and 125a-5p) were significantly increased, while there was a decreased expression of miR-105-3p in PCOS patients with respect to the control. Literature has shown that the above seven miRNAs were associated with HA in PCOS. Furthermore, 31 770 genes were predicted to be targets of the 263 differentially expressed microRNAs. GO analysis and the KEGG pathway database showed involvement of these target genes in HA in PCOS. These results suggest the presence of differentially expressed miRNAs in the follicular fluid of women with PCOS/HA versus women in the control group. The potential role of these microRNAs was elucidated using bioinformatics tools and was found to be involved in the regulation of different pathways, biological functions, and cellular components underlying PCOS. The results of this research may reveal new mechanisms of PCOS/HA and suggest potential treatment targets. PMID- 29193230 TI - Deep Infiltrating Endometriosis: Comparison Between 2-Dimensional Ultrasonography (US), 3-Dimensional US, and Magnetic Resonance Imaging. AB - OBJECTIVES: To evaluate the diagnostic accuracy of 2-dimensional (2D) and 3 dimensional (3D) transvaginal ultrasonography (US) in comparison with magnetic resonance imaging (MRI) for identification of deep infiltrating endometriosis. METHODS: In this prospective observational study, 159 premenopausal women who underwent surgery for a clinical suspicion of deep infiltrating endometriosis were prospectively enrolled. All women underwent 2DUS, 3DUS, and MRI. The following 3 locations of deep endometriosis were considered: (1) intestinal; (2) other posterior lesions (retrocervical septum, rectovaginal septum, uterosacral ligaments, and vaginal fornix); and (3) anterior. The sensitivity, specificity, positive predictive value, and negative predictive value of 2D and 3D transvaginal US in comparison with MRI were determined. RESULTS: Intestinal deep infiltrating endometriosis was identified by 2DUS in 56 of 66 patients, by 3DUS in 59 of 66, and by MRI in 61 of 66. A receiver operating characteristic curve analysis showed optimal results for 2DUS, 3DUS, and MRI (areas under the curve, 0.86, 0.915, and 0.935, respectively) with a statistically significant difference between 2DUS and MRI (P = .0103), even when the 95% confidence interval showed an overlap. Other posterior deep infiltrating endometriosis was identified by 2DUS in 55 of 75 patients, by 3DUS in 65 of 75, and by MRI in 66 of 75. A receiver operating characteristic curve analysis showed very good results for 2DUS, 3DUS, and MRI (areas under the curve, 0.801, 0.838, and 0.857) with no statistically significant differences. In the 12 women with deep infiltrating endometriosis in the anterior location, the nodules were correctly identified by 2DUS in 3 of 12 patients, by 3DUS in 5 of 12, and by MRI in 6 of 12. CONCLUSIONS: Our results seem to suggest that there is a statistically significant difference between 2DUS and MRI for the intestinal location of deep infiltrating endometriosis, whereas no differences were found among the techniques for the other locations. PMID- 29193231 TI - Using MRI cell tracking to monitor immune cell recruitment in response to a peptide-based cancer vaccine. AB - PURPOSE: MRI cell tracking can be used to monitor immune cells involved in the immunotherapy response, providing insight into the mechanism of action, temporal progression of tumor growth, and individual potency of therapies. To evaluate whether MRI could be used to track immune cell populations in response to immunotherapy, CD8+ cytotoxic T cells, CD4+ CD25+ FoxP3+ regulatory T cells, and myeloid-derived suppressor cells were labeled with superparamagnetic iron oxide particles. METHODS: Superparamagnetic iron oxide-labeled cells were injected into mice (one cell type/mouse) implanted with a human papillomavirus-based cervical cancer model. Half of these mice were also vaccinated with DepoVaxTM (ImmunoVaccine, Inc., Halifax, Nova Scotia, Canada), a lipid-based vaccine platform that was developed to enhance the potency of peptide-based vaccines. RESULTS: MRI visualization of CD8+ cytotoxic T cells, regulatory T cells, and myeloid-derived suppressor cells was apparent 24 h post-injection, with hypointensities due to iron-labeled cells clearing approximately 72 h post injection. Vaccination resulted in increased recruitment of CD8+ cytotoxic T cells, and decreased recruitment of myeloid-derived suppressor cells and regulatory T cells to the tumor. We also found that myeloid-derived suppressor cell and regulatory T cell recruitment were positively correlated with final tumor volume. CONCLUSION: This type of analysis can be used to noninvasively study changes in immune cell recruitment in individual mice over time, potentially allowing improved application and combination of immunotherapies.

PMID- 29193233 TI - Development and validation of an LC-MS/MS method for the determination of a novel thienoquinolin urea transporter inhibitor PU-48 in rat plasma and its application to a pharmacokinetic study. AB - A specific, sensitive and stable high-performance liquid chromatographic-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the quantitative determination of methyl 3-amino-6-methoxythieno [2,3-b]quinoline-2 carboxylate (PU-48), a novel diuretic thienoquinolin urea transporter inhibitor in rat plasma. In this method, the chromatographic separation of PU-48 was achieved with a reversed-phase C18 column (100 * 2.1 mm, 3 MUm) at 35 degrees C. The mobile phase consisted of acetonitrile and water with 0.05% formic acid added with a gradient elution at flow rate of 0.3 mL/min. Samples were detected with the triple-quadrupole tandem mass spectrometer with multiple reaction monitoring mode via electrospray ionization source in positive mode. The retention time were 6.2 min for PU-48 and 7.2 min for megestrol acetate (internal standard, IS). The monitored ion transitions were mass-to-charge ratio (m/z) 289.1 -> 229.2 for PU 48 and m/z 385.3 -> 267.1 for the internal standard. The calibration curve for PU 48 was linear over the concentration range of 0.1-1000 ng/mL (r2 > 0.99), and the lower limit of quantitation was 0.1 ng/mL. The precision, accuracy and stability of the method were validated adequately. The developed and validated method was successfully applied to the pharmacokinetic study of PU-48 in rats. PMID- 29193234 TI - Dexmedetomidine as an adjuvant to 0.5% ropivacaine in ultrasound-guided axillary brachial plexus block. AB - WHAT IS KNOWN AND OBJECTIVE: The aim of this study was to elucidate the effect of dexmedetomidine added to ropivacaine on the onset and duration of sensory and motor block and duration of analgesia of ultrasound-guided axillary brachial plexus block. METHODS: Thirty-seven ASA physical status I-II patients with elective forearm and hand surgery under ultrasound-guided axillary brachial plexus block were randomly divided into 2 groups. Patients in ropivacaine dexmedetomidine group (group RD, n = 19) received 15 mL of 0.5% ropivacaine with 100 MUg (1 mL) dexmedetomidine, and patients in ropivacaine group (group R, n = 18) received 15 mL of 0.5% ropivacaine with 1 mL of normal saline. Onset time and duration of sensory and motor block and duration of analgesia were assessed. RESULTS AND DISCUSSION: Duration of sensory block (U-value = 35, P < .001), duration of motor block (P = .001) and duration of analgesia (P < .001) were extended in group RD compared to group R. Onset time of sensory block in group RD was significantly faster than in group R (U-value = 65.5, P = .001). Onset time of motor block showed no significant difference between the 2 groups (U-value = 116.5, P = .096). Adverse reactions were reported only in group RD (bradycardia in 2 and hypotension in 3 patients). WHAT IS NEW AND CONCLUSION: Our study indicated that dexmedetomidine 100 MUg as adjuvant on ultrasound-guided axillary plexus block significantly prolonged the duration of sensory block and analgesia, as well as accelerated the time to onset of sensory block. These results should be weighed against the increased risks of motor block prolongation, transient bradycardia and hypotension and allow for attentive optimism, only if prolonged clinical trials provide a definitive answer. PMID- 29193235 TI - Prospective aquatic risk assessment for chemical mixtures in agricultural landscapes. AB - Environmental risk assessment of chemical mixtures is challenging because of the multitude of possible combinations that may occur. Aquatic risk from chemical mixtures in an agricultural landscape was evaluated prospectively in 2 exposure scenario case studies: at field scale for a program of 13 plant-protection products applied annually for 20 yr and at a watershed scale for a mixed land-use scenario over 30 yr with 12 plant-protection products and 2 veterinary pharmaceuticals used for beef cattle. Risk quotients were calculated from regulatory exposure models with typical real-world use patterns and regulatory acceptable concentrations for individual chemicals. The results could differentiate situations when there was concern associated with single chemicals from those when concern was associated with a mixture (based on concentration addition) with no single chemical triggering concern. Potential mixture risk was identified on 0.02 to 7.07% of the total days modeled, depending on the scenario, the taxa, and whether considering acute or chronic risk. Taxa at risk were influenced by receiving water body characteristics along with chemical use profiles and associated properties. The present study demonstrates that a scenario-based approach can be used to determine whether mixtures of chemicals pose risks over and above any identified using existing approaches for single chemicals, how often and to what magnitude, and ultimately which mixtures (and dominant chemicals) cause greatest concern.

PMID- 29193236 TI - Inhibitory effect of naringenin via IL-13 level regulation on thymic stromal lymphopoietin-induced inflammatory reactions. AB - Naringenin (NG) has various beneficial properties, such as anti-cancer and anti inflammatory effects. Thymic stromal lymphopoietin (TSLP) induces mast cell proliferation and inflammatory reactions. The aim of this study was to investigate the regulatory effect of NG on TSLP-induced mast cell proliferation and inflammatory reactions using human mast cell line (HMC-1) cells. HMC-1 cells were pre-treated with NG and then treated with TSLP. HMC-1 cells proliferation was determined by quantifying bromodeoxyuridine incorporation. Levels of anti apoptotic and pro-apoptotic factors were analyzed by western blot analysis. The productions and mRNA expressions of interleukin (IL)-13 and tumour necrosis factor-alpha (TNF-alpha) were analyzed by ELISA and quantitative real-time PCR. We found that NG significantly attenuated HMC-1 cells proliferation and Ki-67 mRNA expression promoted by TSLP. NG significantly suppressed mRNA expression of TSLP receptor and IL-7 receptor alpha in TSLP-treated HMC-1 cells. NG significantly down-regulated levels of phosphorylated-signal transducer and activation of transcription 6 and murine double-minute 2 in TSLP-treated HMC-1 cells, up-regulated levels of cleaved poly ADP-ribose polymerase and p53 in TSLP treated HMC-1 cells. Furthermore, NG significantly decreased the productions and mRNA expressions of IL-13 and TNF-alpha in TSLP-treated HMC-1 cells. These results suggest NG has an inhibitory effect on mast cell-mediated allergic inflammatory reactions. PMID- 29193237 TI - Cloning and analysis of peptidoglycan recognition protein-LC and immune deficiency from the diamondback moth, Plutella xylostella. AB - Peptidoglycan (PGN) exists in both Gram-negative and Gram-positive bacteria as a component of the cell wall. PGN is an important target to be recognized by the innate immune system of animals. PGN recognition proteins (PGRP) are responsible for recognizing PGNs. In Drosophila melanogaster, PGRP-LC and IMD (immune deficiency) are critical for activating the Imd pathway. Here, we report the cloning and analysis of PGRP-LC and IMD (PxPGRP-LC and PxIMD) from diamondback moth, Plutella xylostella (L.), the insect pest of cruciferous vegetables. PxPGRP LC gene consists of six exons encoding a polypeptide of 308 amino acid residues with a transmembrane region and a PGRP domain. PxIMD cDNA encodes a polypeptide of 251 amino acid residues with a death domain. Sequence comparisons indicate that they are characteristic of Drosophila PGRP-LC and IMD homologs. PxPGRP-LC and PxIMD were expressed in various tissues and developmental stages. Their mRNA levels were affected by bacterial challenges. The PGRP domain of PxPGRP-LC lacks key residues for the amidase activity, but it can recognize two types of PGNs. Overexpression of full-length and deletion mutants in Drosophila S2 cells induced expression of some antimicrobial peptide genes. These results indicate that PxPGRP-LC and PxIMD may be involved in the immune signaling of P. xylostella. This study provides a foundation for further studies of the immune system of P. xylostella. PMID- 29193238 TI - Experiences of living with a sexually transmitted disease: an integrative review. AB - PURPOSE: This integrative review describes experiences related to living with a sexually transmitted disease (STD). DESIGN: The data search was conducted using the CINAHL, MEDLINE (Ovid), PsycINFO and PubMed databases between the years 2000 and 2016. A manual search was also used. The retrieved data consisted of 33 original articles which were analysed using deductive and inductive content analysis. RESULTS: Based on the results, an infected person has a need for information about STDs and experiences emotions such as a loss of purity and control over his/her body. In addition, the ego of the infected person is wounded due to the infection. Concerns about the results of treatments, suffering side effects, and experiences of unprofessional behaviour by nursing staff are related to the treatment of an STD. Having an STD in everyday life means coping with a changing condition, but there are resources that can provide support. The quality of life can also be negatively affected by an STD, and a future with an STD can manifest different hopes and concerns. In relation to other people, an STD has a marked effect, especially concerning sexual relations. The person's sex life can fade away; however, it may remain as an enjoyable experience. The infected person may also adopt safer sexual behaviours or continue with a risk-taking behaviour. CONCLUSION: The results of this review can be used in the development of nursing practices, as well as be used in the prevention of STDs. PMID- 29193239 TI - Calibration of silicone rubber rods as passive samplers for pesticides at two different flow velocities: Modeling of sampling rates under water boundary layer and polymer control. AB - There is a need to determine time-weighted average concentrations of polar contaminants such as pesticides by passive sampling in environmental waters. Calibration data for silicone rubber-based passive samplers are lacking for this class of compounds. The calibration data, sampling rate (Rs ), and partition coefficient between silicone rubber and water (Ksw ) were precisely determined for 23 pesticides and 13 candidate performance reference compounds (PRCs) in a laboratory calibration system over 14 d for 2 water flow velocities, 5 and 20 cm s-1 . The results showed that an in situ exposure duration of 7 d left a silicone rubber rod passive sampler configuration in the linear or curvilinear uptake period for 19 of the pesticides studied. A change in the transport mechanism from polymer control to water boundary layer control was observed for pesticides with a log Ksw of approximately 3.3. The PRC candidates were not fully relevant to correct the impact of water flow velocity on Rs . We therefore propose an alternative method based on an overall resistance to mass transfer model to adjust Rs from laboratory experiments to in situ hydrodynamic conditions. We estimated diffusion coefficients (Ds ) and thickness of water boundary layer (deltaw ) as adjustable model parameters. Log Ds values ranged from -12.13 to 10.07 m2 s-1 . The estimated deltaw value showed a power function correlation with water flow velocity. Environ Toxicol Chem 2018;37:1208-1218. (c) 2017 SETAC. PMID- 29193240 TI - Intracranial fetus-in-fetu with numerous fully developed organs. AB - Fetus in fetu (FIF) is an extremely rare anomaly featuring a monozygotic, diamniotic, parasitic twin, enclosed within its host twin. It is characterized by the presence of vertebrae and well-developed organs in a fetiform mass. Only 18 cases of intracranial FIF have been published. Of them, only five cases were prenatally detected. This study prenatally demonstrated triplet FIFs at 31 weeks within amniotic-like sac in the fetal skull, consisting of multiple well-defined organs. The FIF attached to the host twin via body stalk containing a single main feeding artery and vein, representing umbilical vessels. Surgical removal was performed at the age of two months. Pathological examination showed the triplet FIF, consisting of numerous well-developed organs (musculocutaneous-skeletal, nervous, respiratory, gastrointestinal systems etc.), with soft tissue/skin coverings, but no vertebral body was seen. Molecular genetic analysis revealed identical genetic mapping among the three FIFs and the host. This case provides strong evidence against Willis's hypothesis but supports Spencer's theory of abnormal twinning. PMID- 29193241 TI - Does informal caregiving affect self-esteem? Results from a population-based study of individuals aged 40 and over in Germany from 2002 to 2014. AB - BACKGROUND: While it is known that informal caregiving is associated with care derived self-esteem cross-sectionally, little is known about the impact of informal caregiving on general self-esteem longitudinally. Thus, we aimed at examining whether informal caregiving affects general self-esteem using a longitudinal approach. METHODS: Data were gathered from a population-based sample of community-dwelling individuals aged 40 and over in Germany from 2002 to 2014 (n = 21 271). General self-esteem was quantified using the Rosenberg scale. Individuals were asked whether they provide informal care regularly. RESULTS: Fixed effects regressions showed no significant effect of informal caregiving on general self-esteem longitudinally. General self-esteem decreased with increasing morbidity, increasing age, decreasing social ties, whereas it was not associated with changes in employment status, marital status and body mass index. Additional models showed that decreases in self-esteem were associated with decreases in functional health and increases in depressive symptoms. CONCLUSION: Our longitudinal study emphasises that the occurrence of informal caregiving did not affect general self-esteem longitudinally. Further research is needed in other cultural settings using panel data methods. PMID- 29193242 TI - A peer learning intervention targeting newly graduated nurses: A feasibility study with a descriptive design based on the Medical Research Council framework. AB - AIMS: The aim of this study was to describe the feasibility of a peer learning intervention targeting newly graduated nurses. Feasibility was tested concerning consistency of the theoretical description of peer learning with empirical findings in a new context, compliance and acceptability, as well as usability of a questionnaire measuring the intended future outcome variables. BACKGROUND: Newly graduated nurses who meet, socialize and share experiences have described supporting each other's ability to cope with stress. Peer learning involves individuals in a similar situation learning from and with each other through interaction. When implementing new interventions, feasibility studies are used to minimize problems in future evaluation studies. DESIGN: Quasi-experimental design with an intervention group, followed over time using descriptive methods. The study was based on the Medical Research Council framework. METHODS: Repeated semi structured interviews, a checklist for fidelity and a questionnaire were conducted with 10 newly graduated nurses from January to March 2015. The intervention's main component included pairs of newly graduated nurses working the same shift and having joint responsibility for a group of patients for a period of 3 weeks. The intervention also included 3 months of regular reflection by the pair. FINDINGS: Using deductive analysis, the peer learning intervention was found to be consistent with the theoretical description. Due to the compliance and acceptability, there were lessons learnt. The tested questionnaire was found to be useful. CONCLUSIONS: This peer learning intervention seems to be feasible in this context. This study will serve as the basis for a future full scale evaluation study. PMID- 29193243 TI - Dioxin-like contaminants are no longer a risk to the American eel (Anguilla rostrata) in Lake Ontario. AB - The embryotoxicity of extracts of American eels (Anguilla rostrata) was measured to determine whether maternally derived contaminants contribute to the declining recruitment of eels to Lake Ontario. Sexually maturing, large yellow and silver eels were sampled in 2007 and 2008 from 5 locations in eastern Canada, including Lake Ontario; positive controls included eels from the Hudson River, United States, and Canal Dessel-Schoten, Belgium (European eel, Anguilla anguilla). Japanese medaka eggs were injected immediately after fertilization with 1 or 10 nL of eel extract and, after 12 d, scored for signs of toxicity. Eel extracts did not cause dioxin-like embryotoxicity, reflecting the low concentrations of total dioxin equivalents measured chemically in these same extracts. Embryo mortality and reduced hatching success at high doses of eel extracts may reflect the bioaccumulation of legacy or emerging chemicals of concern. The results were consistent with long-term trends of declining concentrations of persistent organic pollutants (POPs) in tissues of eels and other fish species from Lake Ontario, trends of declining embryotoxicity of eel tissue extracts, and recent increases of recruitment of juvenile eels to Lake Ontario. If dioxin-like compounds contributed in the past to the decline of recruitment and abundance of American eels in Lake Ontario, these data suggest that recruitment should recover, following the same trends as the recovery of lake trout reproduction in Lake Ontario.

AB - PURPOSE: Ultrafast single-shot T2 -weighted images are common practice in fetal MR exams. However, there is limited experience with fetal T1 -weighted acquisitions. This study aims at establishing a robust framework that allows fetal T1 -weighted scans to be routinely acquired in utero at 3T. METHODS: A 2D gradient echo sequence with an adiabatic inversion was optimized to be robust to fetal motion and maternal breathing optimizing grey/white matter contrast at the same time. This was combined with slice to volume registration and super resolution methods to produce volumetric reconstructions. The sequence was tested on 22 fetuses. RESULTS: Optimized grey/white matter contrast and robustness to fetal motion and maternal breathing were achieved. Signal from cerebrospinal fluid (CSF) and amniotic fluid was nulled and 0.75 mm isotropic anatomical reconstructions of the fetal brain were obtained using slice-to-volume registration and super resolution techniques. Total acquisition time for a single stack was 56 s, all acquired during free breathing. Enhanced sensitivity to normal anatomy and pathology with respect to established methods is demonstrated. A direct comparison with a 3D spoiled gradient echo sequence and a controlled motion experiment run on an adult volunteer are also shown. CONCLUSION: This paper describes a robust framework to perform T1 -weighted acquisitions and reconstructions of the fetal brain in utero. Magn Reson Med 80:137-146, 2018.

PMID- 29193245 TI - Review article: gastro-oesophageal reflux disease in asthma and chronic obstructive pulmonary disease. AB - BACKGROUND: When gastro-oesophageal reflux is causing symptoms or lesions in the oesophagus, this is referred to as gastro-oesophageal reflux disease (GERD). GERD can manifest itself through typical symptoms (heartburn, regurgitation) or may lead to extra-oesophageal symptoms. Extra-oesophageal manifestations of GERD gained increasing attention over the last decade, especially respiratory disorders, because of the prevalent co-occurrence with GERD. The role of GERD in the pathogenesis of respiratory disorders has become a topic of intense discussion. AIM: To provide an overview of the current knowledge on the role of GERD in asthma and chronic obstructive pulmonary disease (COPD). METHODS: PubMed was searched for relevant articles using the keywords: GERD, asthma, COPD, prevalence, treatment. Case reports were excluded, only English language articles were considered. RESULTS: Estimates for the prevalence of GERD in asthma range from 30% to 90%, compared to an average of 24% in controls. In COPD patients, the prevalence of GERD ranges from 19% to 78% compared to an average of 18% in controls. These data indicate an increased prevalence of GERD in patients with asthma and COPD, although causality is not established and GERD treatment yielded inconsistent effects. Literature supports GERD as a risk factor for COPD exacerbations and a predictor of the 'frequent-exacerbator'-phenotype. CONCLUSIONS: Despite the high prevalence of GERD in asthma and COPD, a causal link is lacking. The results of anti-reflux therapy on pulmonary outcome are inconsistent and contradictory. Future studies will need to identify subgroups of asthmatics and COPD patients that may benefit from anti-reflux therapy (nocturnal or silent reflux). PMID- 29193246 TI - Transcutaneous carbon dioxide application with hydrogel prevents muscle atrophy in a rat sciatic nerve crush model. AB - : The acceleration of nerve regeneration remains a clinical challenge. We previously demonstrated that transcutaneous CO2 application using a novel hydrogel increases the oxygen concentration in local tissue via an "artificial Bohr effect" with the potential to prevent muscle atrophy. In this study, we investigated the effect of transcutaneous CO2 administration on limb function after peripheral nerve injury in a rat sciatic nerve injury model. In total, 73 Sprague-Dawley rats were divided into a sham group, a control group (crush injury to sciatic nerve and no treatment) or a CO2 group (crush injury with transcutaneous CO2 application). CO2 was administered percutaneously for 20 min five times per week. Scores for the sciatic function index and pinprick test were significantly higher in the CO2 group than control group. The muscle wet weight ratios of the tibialis anterior and soleus muscles were higher in the CO2 group than control group. Electrophysiological examination showed that the CO2 group had higher compound motor action potential amplitudes and shorter distal motor latency than the control group. Histological examination of the soleus muscle sections at postoperative week 2 showed shorter fiber diameter in the control group than in the CO2 group. The mRNA expression of Atrogin-1 and MuRF-1 was lower, mRNA expression of VEGF and myogenin and MyoD was higher in CO2 group at postoperative week 2 compared to the control group. CLINICAL SIGNIFICANCE: Transcutaneous CO2 application has the therapeutic potential to accelerate the recovery of muscle atrophy in peripheral nerve injury. (c) 2017 Orthopaedic Research Society.

PMID- 29193247 TI - Randomized, Double-Blind, Crossover, Clinical-End-Point Pilot Study to Examine the Use of Exhaled Nitric Oxide as a Bioassay for Dose Separation of Inhaled Fluticasone Propionate. AB - This was a randomized, double-blind, crossover, clinical-end-point pilot study examining the hypothesis that inhaled fluticasone propionate decreases exhaled nitric oxide (eNO) concentrations within a week of beginning treatment and shows evidence of dose separation across the marketed dose range. Subjects had a >=6 month history of asthma and screening eNO >=60 parts per billion. At the start of each treatment period, eNO was >=55 parts per billion, and forced expiratory volume in 1 second was >=50% predicted. Subjects attended a clinic visit daily on consecutive mornings during each of 3 1-week treatment periods to measure eNO and receive once-daily doses of 100/50, 250/50, or 500/50 fluticasone propionate/salmeterol combination product (Advair(r) Diskus). Daily eNO value recorded was the highest of 3 measurements; 1 inhalation of treatment was then administered. Procedures were repeated for 3 treatment cycles, separated by 14 day minimum washouts. A total of 105 subjects were screened; 22 were randomized; and 17 completed all treatments. Mean percentage eNO decrease (standard deviation) from day 1 baseline for each treatment period was 36.6 (+/-18.7), 45.3 (+/-16.5), and 54.6 (+/-12.5) with Advair(r) 100/50, 250/50, and 500/50, respectively. Mean percentage decrease in eNO across each treatment (dose) was modeled using a mixed-model ANOVA. Although the overall treatment was significant (P = .0015), because of the relatively small sample size and within-subject variability, only the 100/50 vs 500/50 (P = .0003) and 250/50 vs 500/50 (P = .047) treatments were significantly different.

AB - Reconstruction of thigh defects is usually straightforward, but in cases of poor soft tissue quality, free flap reconstruction is not possible due to the absence of recipient vessels. The turbocharge technique may increase the viable, vascularized area of a flap. In this report we present a case of the use of a turbocharged bilateral pedicled DIEP flap for reconstruction of thigh defect without recipient vessels.

Six weeks later, complete tumor excision and a femoropopliteal bypass with contralateral saphenous vein was performed. In the following days the wound had dehiscence, infection, necrosis of the surrounding muscles and exposure of femoropopliteal bypass. No recipient vessels were available for free flap and critical limb ischemia due to bypass thrombosis was detected. The reconstruction of a large thigh defect (30 * 12 cm) and the coverage of a femoropopliteal bypass with a turbocharged bilateral pedicled DIEP flap was performed. A flap including the entire infraumbilical tissue was designed and the anastomosis of the proximal stump of the right inferior epigastric vessels with the distal ends of the inferior left epigastric vessels was performed to increase the viable area. The flap survived without any complications during the postoperative period. At 12 month follow up, coverage was stable with no tumor recurrence. Our result suggests that a turbocharged bilateral pedicled DIEP flap may be an option for reconstructing large tissue defects when no recipient vessels are available for free flap.

AB - BACKGROUND AND AIM: This study investigated the prognostic impact of muscle volume loss (MVL) and muscle function decline in patients undergoing resection for hepatocellular carcinoma (HCC). METHODS: This study enrolled 171 naive HCC patients treated with resection from 2007 to 2015, after excluding those lacking spirometry or computed tomography findings, who had received non-curative treatments, or with restrictive or obstructive lung disorders. The median peak expiratory flow rate (%PEF) was set as the cut-off value for muscle function decline, and MVL was diagnosed using a previously reported value. Clinical backgrounds and prognosis were retrospectively evaluated. RESULTS: Overall survival rate was lower in the MVL (n = 35) as compared with the non-MVL (n = 136) group (1/3/5-year overall survival rate = 88.2%/81.6%/55.6% vs 91.0%/81.5%/74.8%, respectively; P = 0.0083), while there were no differences regarding hepatic function or tumor burden between the groups. Child-Pugh class B (hazard ratio [HR] 3.510, 95% confidence interval [CI]: 1.558-7.926, P = 0.0025), beyond Milan criteria (HR 1.866, 95%CI: 1.024-3.403, P = 0.042), and presence of MVL (HR 1.896, 95%CI: 1.052-3.416, P = 0.033) were significant prognostic factors. The decreased %PEF group (n = 84) showed a higher rate of postoperative delirium than the others (n = 87) (27.4% vs 11.5%, P = 0.0088). The cut-off values for %PEF and age for postoperative delirium were 63.3% (area under receiver operating characteristic [AUROC] 0.697) and 73 years old (AUROC 0.734), respectively. Delirium was observed in 50.0% (14/28) of patients with both factors, 23.8% (15/63) of those with 1 factor, and 5.0% (4/80) of those without either factor. CONCLUSION: Muscle volume loss is an independent prognostic factor in HCC patients treated with surgical resection, while advanced age and decreased muscle function might indicate high risk for postoperative delirium.

AB - PURPOSE: T2 -weighted sequences are particularly sensitive to the radiofrequency (RF) field inhomogeneity problem at ultra-high-field because of the errors accumulated by the imperfections of the train of refocusing pulses. As parallel transmission (pTx) has proved particularly useful to counteract RF heterogeneities, universal pulses were recently demonstrated to save precious time and computational efforts by skipping B1 calibration and online RF pulse tailoring. Here, we report a universal RF pulse design for non-selective refocusing pulses to mitigate the RF inhomogeneity problem at 7T in turbo spin echo sequences with variable flip angles. METHOD: Average Hamiltonian theory was used to synthetize a single non-selective refocusing pulse with pTx while optimizing its scaling properties in the presence of static field offsets. The design was performed under explicit power and specific absorption rate constraints on a database of 10 subjects using a 8Tx-32Rx commercial coil at 7T. To validate the proposed design, the RF pulses were tested in simulation and applied in vivo on 5 additional test subjects. RESULTS: The root-mean-square rotation angle error (RA-NRMSE) evaluation and experimental data demonstrated great improvement with the proposed universal pulses (RA-NRMSE ~8%) compared to the standard circularly polarized mode of excitation (RA-NRMSE ~26%). CONCLUSION: This work further completes the spectrum of 3D universal pulses to mitigate RF field inhomogeneity throughout all 3D MRI sequences without any pTx calibration. The approach returns a single pulse that can be scaled to match the desired flip angle train, thereby increasing the modularity of the proposed plug and play approach. Magn Reson Med 80:53-65, 2018.

AB - Gynaecomastia may be due to medication, chronic liver or kidney disease, hypogonadism (primary or secondary to pituitary disease) or hyperthyroidism. Having excluded these aetiologies, it is imperative to be vigilant for underlying malignancy causing gynaecomastia. These include human chorionic gonadotrophin secreting testicular and extratesticular tumours and oestrogen-secreting testicular tumours and feminising adrenal tumours.

AB - The Rab-family GTPases mainly regulate intracellular vesicle transport, and play important roles in the innate immune response in invertebrates. However, the function and signal transduction of Rab proteins in immune reactions remain unclear in silkworms. In this study, we analyzed a Rab-related protein of silkworm Bombyx mori (BmRABRP) by raising antibodies against its bacterially expressed recombinant form. Tissue distribution analysis showed that BmRABRP mRNA and protein were high expressed in the Malpighian tubule and fat body, respectively. However, among the different stages, only the fourth instar larvae and pupae showed significant BmRABRP levels. After challenge with four pathogenic microorganisms (Escherichia coli, BmNPV, Beauveria bassiana, Micrococcus luteus), the expression of BmRABRP mRNA in the fat body was significantly upregulated. In contrast, the BmRABRP protein was significantly upregulated after infection with BmNPV, while it was downregulated by E. coli, B. bassiana, and M. luteus. A specific dsRNA was used to explore the immune function and relationship between BmRABRP and the JAK-STAT signaling pathway. After BmRABRP gene interference, significant reduction in the number of nodules and increased mortality suggested that BmRABRP plays an important role in silkworm's response to bacterial challenge. In addition, four key genes (BmHOP, BmSTAT, BmSOCS2, and BmSOCS6) of the JAK-STAT signaling pathway showed significantly altered expressions after BmRABRP silencing. BmHOP and BmSOCS6 expressions were significantly decreased, while BmSTAT and BmSOCS2 were significantly upregulated. Our results suggested that BmRABRP is involved in the innate immune response against pathogenic microorganisms through the JAK-STAT signaling pathway in silkworm.

PMID- 29193254 TI - Obstacles and challenges for tissue engineering and regenerative medicine: Australian nuances. AB - The clinical need and historical approaches to tissue engineering as applied to regenerative medicine are introduced, along with comments on activities in this field around Australia, and then the huge advances for tissue culture studies are discussed (Part A). Combinations of human stem cells and new approaches for generating bioscaffolds present great opportunities for in vitro studies of basic biology and physiology, drug testing and high throughput screening for the pharmaceutical industry, and the advanced tissue engineering of organs and devices. The future here is bright. The major obstacles arise with in vivo application of these bioengineering advances using animal models and humans (Part B), and the complexity of living tissues and the challenges of increased scale required for clinical translation to the large human situation are first discussed. While clinical success seen with implantation of acellular bioscaffolds (with population by host cells) is likely to expand for human use, the major challenge relates to (generally) low survival in vivo of (donor or autologous) cells that are expanded and grown in tissue culture before implantation into the living body. Another major challenge is revascularisation of implanted tissues/organs at the human scale. The innovative approaches and rapid advances in tissue bioengineering hold great promise for overcoming these major obstacles and extending the clinical applications of these technologies. PMID- 29193255 TI - Evaluation of the single medial circummuscular perforator DIEP flap: Outcomes and comparison to traditional transmuscular single perforator flap. AB - INTRODUCTION: Successful breast reconstruction using deep inferior epigastric perforator (DIEP) flaps depends on optimal perforator choice. Circummuscular wraparound medial perforators allow for no rectus dissection and minimal fascial incisions, often presenting as an ideal option. The aim of our study is to evaluate outcomes of the single medial wraparound perforator flap in comparison to more traditional transmuscular single-perforator DIEP flaps. PATIENTS AND METHODS: A retrospective chart review was conducted of all DIEP flaps performed by the senior author from 2011 to 2016, yielding 269 flaps on 157 patients. For this study, we included all patients who underwent reconstruction of the breast(s) and possessed circummuscular perforators arising from the DIE vessels. A control group consisted of all consecutive patients with transmuscular one perforator DIEP flaps. Patient details and their postoperative outcomes were collected. RESULTS: In our study, eight patients (5.1%) were of the medial wraparound variety. Sixteen control patients (10.2%) with similar comorbidities had flaps that were of the more traditional single perforator transmuscular variety. There was a slight trend toward decreased operative time in the medial wraparound group, however, it was not found to be statistically significant (536 +/- 81 vs. 572 +/- 84 min, P = .377). Complication profiles were similar between groups (25.0 vs. 18.8%, P = .722), with no increased rates of fat necrosis in the wraparound cohort. CONCLUSION: Based on our findings, using a medial wraparound perforator is a safe and reliable option when compared with a single transmuscular perforator DIEP flap. Choosing the wraparound perforator may show benefit as it eliminates muscular dissection and nerve damage, and tends to minimize fascial incision length. PMID- 29193256 TI - Post-Traumatic Heterotopic Ossification: An Old Problem in Need of New Solutions. AB - Heterotopic ossification (HO) is the formation of pathological bone in ectopic sites and it can have serious consequences for functional outcomes. For many years, its main clinical relevance was as a rare complication of elective joint arthroplasty or CNS injury and a number of prophylaxes were developed to mitigate against it in these settings. As a consequence of changes in patterns of wounding and survival in conflicts since the turn of the century, post-traumatic HO has become much more common and case severity has increased. It represents one of the main barriers to rehabilitation in a large cohort of combat-injured patients. However, extant prophylaxes have not been shown to be effective or appropriate in this patient cohort. In addition, the lack of reliable early detection or means of predicting which patients will develop HO is another barrier to effective prevention. This review examines the current state of understanding of post traumatic HO including the historical context, epidemiology, pathophysiology, clinical issues, currently prophylaxis and detection, management, and potential future approaches. Our aims are to highlight the current lack of effective means of early detection and prevention of HO after major trauma and to stimulate research into novel solutions to this challenging problem.

PMID- 29193257 TI - Fundamental structural and functional properties of Aquaporin ion channels found across the kingdoms of life. AB - Aquaporin (AQP) channels in the major intrinsic protein (MIP) family are known to facilitate transmembrane water fluxes in prokaryotes and eukaryotes. Some classes of AQPs also conduct ions, glycerol, urea, CO2 , nitric oxide, and other small solutes. Ion channel activity has been demonstrated for mammalian AQPs 0, 1, 6, Drosophila Big Brain (BIB), soybean nodulin 26, and rockcress AtPIP2;1. More classes are likely to be discovered. Newly identified blockers are providing essential tools for establishing physiological roles of some of the AQP dual water and ion channels. For example, the arylsulfonamide AqB011 which selectively blocks the central ion pore of mammalian AQP1 has been shown to impair migration of HT29 colon cancer cells. Traditional herbal medicines are sources of selective AQP1 inhibitors that also slow cancer cell migration. The finding that plant AtPIP2;1 expressed in root epidermal cells mediates an ion conductance regulated by calcium and protons provided insight into molecular mechanisms of environmental stress responses. Expression of lens MIP (AQP0) is essential for maintaining the structure, integrity and transparency of the lens, and Drosophila BIB contributes to neurogenic signalling pathways to control the developmental fate of fly neuroblast cells; however, the ion channel roles remain to be defined for MIP and BIB. A broader portfolio of pharmacological agents is needed to investigate diverse AQP ion channel functions in situ. Understanding the dual water and ion channel roles of AQPs could inform the development of novel agents for rational interventions in diverse challenges from agriculture to human health. PMID- 29193258 TI - Comparative transcriptome analysis provides insights of anti-insect molecular mechanism of Cassia obtusifolia trypsin inhibitor against Pieris rapae. AB - Pieris rapae, a serious Lepidoptera pest of cultivated crucifers, utilizes midgut enzymes to digest food and detoxify secondary metabolites from host plants. A recombinant trypsin inhibitor (COTI) from nonhost plant, Cassia obtusifolia, significantly decreased activities of trypsin-like proteases in the larval midgut on Pieris rapae and could suppress the growth of larvae. In order to know how COTI took effect, transcriptional profiles of P. rapae midgut in response to COTI was studied. A total of 51,544 unigenes were generated and 45.86% of which had homologs in public databases. Most of the regulated genes associated with digestion, detoxification, homeostasis, and resistance were downregulated after ingestion of COTI. Meanwhile, several unigenes in the integrin signaling pathway might be involved in response to COTI. Furthermore, using comparative transcriptome analysis, we detected differently expressing genes and identified a new reference gene, UPF3, by qRT-polymerase chain reaction (PCR). Therefore, it was suggested that not only proteolysis inhibition, but also suppression of expression of genes involved in metabolism, development, signaling, and defense might account for the anti-insect resistance of COTI. PMID- 29193259 TI - Lipopolysaccharide levels adherent to PM2.5 play an important role in particulate matter induced-immunosuppressive effects in mouse splenocytes. AB - Epidemiological studies show that exposure to ambient particulate matter (PM) is associated with serious adverse health effects, including, but not limited to, those on the respiratory system. In the present study, we investigated the splenic response in mice administered PM of <= 2.5 MU m diameter (PM2.5). Male BALB/c mice (7 or 8 weeks old) were intratracheally administered PM2.5 (0.1 mg) four times, at 2 week intervals, and dissected 24 h after the final administration. The effect of six types of PM2.5, collected in Shenyang or Beijing (China) and Kitakyushu (Japan), on splenocytes was examined. Our results revealed a strong correlation between the levels of lipopolysaccharide (LPS), but not that of beta-glucan and polycyclic aromatic hydrocarbons, attached to PM2.5 and the effect of PM2.5 on cell activity. PM2.5 with a low amount of LPS (PM2.5LL) reduced splenocyte mitogen-induced proliferation and cytokine production compared with that in control mice. The suppressive effects of PM2.5LL on proliferation and interleukin-2 production in splenocytes were rescued by the antioxidant N-acetylcysteine. Expression of heme oxygenase-1 was elevated after PM2.5LL administration, particularly in CD11b + cells, while no elevation was observed in CD4+ , CD8+ or B220+ cells. Further, dissociation of the nuclear factor erythroid 2-related factor 2 from Kelch-like ECH-associating protein 1 was observed in splenocytes of PM2.5LL-administered mice. These data suggest that LPS attached to PM2.5 modulates the splenocyte immune responses to PM2.5. PMID- 29193260 TI - RACER-GRASP: Respiratory-weighted, aortic contrast enhancement-guided and coil unstreaking golden-angle radial sparse MRI. AB - PURPOSE: To develop and evaluate a novel dynamic contrast-enhanced imaging technique called RACER-GRASP (Respiratory-weighted, Aortic Contrast Enhancement guided and coil-unstReaking Golden-angle RAdial Sparse Parallel) MRI that extends GRASP to include automatic contrast bolus timing, respiratory motion compensation, and coil-weighted unstreaking for improved imaging performance in liver MRI. METHODS: In RACER-GRASP, aortic contrast enhancement (ACE) guided k space sorting and respiratory-weighted sparse reconstruction are performed using aortic contrast enhancement and respiratory motion signals extracted directly from the acquired data. Coil unstreaking aims to weight multicoil k-space according to streaking artifact level calculated for each individual coil during image reconstruction, so that coil elements containing a high level of streaking artifacts contribute less to the final results. Self-calibrating GRAPPA operator gridding was applied as a pre-reconstruction step to reduce computational burden in the subsequent iterative reconstruction. The RACER-GRASP technique was compared with standard GRASP reconstruction in a group of healthy volunteers and patients referred for clinical liver MR examination. RESULTS: Compared with standard GRASP, RACER-GRASP significantly improved overall image quality (average score: 3.25 versus 3.85) and hepatic vessel sharpness/clarity (average score: 3.58 versus 4.0), and reduced residual streaking artifact level (average score: 3.23 versus 3.94) in different contrast phases. RACER-GRASP also enabled automatic timing of the arterial phases. CONCLUSIONS: The aortic contrast enhancement-guided sorting, respiratory motion suppression and coil unstreaking introduced by RACER-GRASP improve upon the imaging performance of standard GRASP for free-breathing dynamic contrast-enhanced MRI of the liver.

PMID- 29193261 TI - Metaanalysis of Mood and Substance Use Disorders in Proximal Risk for Suicide Deaths. AB - Evidence for proximal risk factors for suicide is based on case-control psychological autopsy studies, with these reports showing that mood and substance use disorders are the most prevalent mental disorders among suicide decedents worldwide and are associated with marked risk. However, moderators of risk and the degree of risk associated with (nonalcohol) drug use disorder are unknown. A comprehensive search was used to identify 35 case-control psychological autopsy studies published worldwide over a 30-year period that were metaanalyzed using random effects models. Major depression, odds ratio (95% confidence interval) = 9.14 (5.53, 15.09), and drug use disorder, OR (95% CI) = 7.18 (3.22, 16.01), had large effect sizes, among other results. Risk estimates associated with major depression were greater in studies with a larger proportion of women and those conducted in Asia compared with other regions. There was no evidence of publication bias or that any one study had a disproportionate impact on findings. Risk for suicide associated with major depression appears to be moderated by sex and/or world region. Drug use disorder is a potent risk factor, illustrating the importance of assessing drug use in clinical risk assessment.

AB - Older individuals with chronic atrial fibrillation (AF) often experience physical symptoms and feel psychologically unwell. In addition, these persons are prescribed lifelong medical treatment that requires regular monitoring. Through 11 individual interviews, this interpretive description study aimed to explore and describe lifelong medical treatment and the need for medical controls as experienced from the perspective of older individuals living with chronic AF. The interviews were performed during 2014-2015; furthermore, they were recorded, transcribed verbatim and analysed for thematic patterns using thematic analysis inspired by Braun and Clarke. Ethical standards were followed throughout the study. The findings revealed one main theme: 'ambivalence in the need of knowledge' showing that lifelong medical treatment and the need for medical controls, in general, meant experiencing feelings of 'it doesn't matter, but it does matter' and 'being in the hands of the healthcare system'. The older persons lacked knowledge about their condition, which generated poor insight into their medical treatment and this in turn affected their daily life. They had thoughts and questions about their medication, but did not have an opportunity to ask the questions because of lack of follow-up from the healthcare system. The findings underscore the negative impact chronic AF has on older people's life and emphasises the need for follow-up and providing information from health care to these individuals.

AB - Serine protease inhibitors play a key role in the immune system of invertebrates by controlling proteolytic cascades. Besides its importance, the knowledge on immune functions of serpins in most of insects is fragmentary. In the present study, we identified serpin-12 from Antheraea pernyi encoding a predicted 402 amino acid residue protein (Apserpin-12). We expressed the recombinant protein in Escherichia coli and the purified protein was used for the synthesis of rabbit anti-Apserpin-12 polyclonal antibodies and functional studies. Quantitative real time ploymerase chain reaction (qRT-PCR) analysis revealed that the knock-down of Apserpin-12 enhanced the prophenoloxidase (PPO) cascade stimulated by Micrococcus luteus in hemolymph, whereas addition of recombinant Apserpin-12 protein along with same elicitor led to down-regulate PPO activation. Following different microbial challenge (E. coli, Beauveria bassiana, M. Luteus, and nuclear polyhedrosis virus), the expression of Apserpin-12 mRNA was induced significantly. Furthermore, the Apserpin-12 double-stranded RNA administration elicited the expression of antimicrobial peptides, while the treatment with recombinant protein suppressed their expression. Tissue profile of Apserpin-12 indicated that it is expressed in all examined tissues, that is, hemolymph, malpighian tubules, midgut, silk gland, integument, and fat body with variation in their transcript levels. We concluded that Apserpin-12 may regulate PPO activation and inhibit the production of antimicrobial peptides in A. pernyi, suggesting important role in its immune system. PMID- 29193265 TI - Substance use disorder and compulsory commitment to care: a care-ethical decision making framework. AB - In the era of deinstitutionalisation of psychiatric patients, steady or even increasing rates of compulsory commitment to care (CCC) are an intriguing phenomenon to analyse. From a clinical, legal and ethical perspective, CCC continues to be a controversial practice in psychiatry, and perhaps even more so when applied to patients with severe substance use disorder (SUD). Several reasons make it controversial. The lack of consensus about the benefits of CCC and professional disagreement about what mental illness and autonomy mean in the case of SUD make it difficult to apply ethically sound clinical decision-making in CCC. Also, the medico-legal framework underlying CCC use sometimes appears to foster the use of reductionist clinical evaluation. Layered on top of these issues is how stakeholders view coercion. There is a discrepancy between clinicians' and patients' perception of coercion, which leads to clinician patient differences on whether CCC is necessary. Moreover, the way in which the evaluation is typically carried out influences patients' perception of coercion and subsequently their motivation for participating fully in treatment. In this article, we explore the value of care ethics, often applied to care practices such as nursing, when applied to more procedural medical practices, such as decision-making regarding CCC. The care-ethical approach views decision-making as part of a dynamic care process, within which the lived experience, interpretative dialogue and promotion of dignity are core features. Embracing this new framework means a paradigm shift in when the therapeutic relationship begins, namely, investing in it occurs while conducting an evaluation for a possible CCC procedure. Unlike in current typical evaluations, early cultivation of the therapeutic relationship enables the patient to participate in the definition of his needs, reduces perceived coercion and negative emotions and enhances treatment motivation. Finally, implications of this novel approach for clinical practice are formulated and discussed. PMID- 29193266 TI - Motion-tolerant diffusion mapping based on single-shot overlapping-echo detachment (OLED) planar imaging. AB - PURPOSE: A new diffusion-mapping method based on single-shot overlapping-echo detachment (DM-OLED) planar-imaging sequence, along with a corresponding separation algorithm, is proposed to achieve reliable quantitative diffusion mapping in a single shot. The method can resist the effects of motion and help in detecting the quick variation of diffusion under different physiological status. METHODS: The echo-planar imaging method is combined with two excitation pulses with small flip angle to gain overlapping-echo signal in a single shot. Then the overlapping signals are separated by a separation algorithm and used for diffusion computation. Numerical simulation, phantom, and in vivo rat experiments were performed to verify the efficiency, accuracy, and motion tolerance of DM OLED. RESULTS: The DM-OLED sequence could obtain reliable diffusion maps within milliseconds in numerical simulation, phantom, and in vivo experiments. Compared with conventional diffusion mapping with spin-echo echo-planar imaging, DM-OLED has higher time resolution and fewer motion-incurred errors in the apparent diffusion coefficient maps. CONCLUSIONS: As a reliable fast diffusion measurement tool, DM-OLED shows promise for real-time dynamic diffusion mapping and functional magnetic resonance imaging. Magn Reson Med 80:200-210, 2018.

AB - Oral tolerance is defined as a state of systemic hyporesponsiveness to an antigen that has been previously administered by the oral route. Many factors affect oral tolerance induction; some of them related to antigen, and some related to the animal. The age of the animal is one of the most important factors that affect oral tolerance as ageing brings many alterations in immune responses. Herein, we demonstrated that both the oral tolerance and pattern of immune reactivity triggered in early life were kept up to 15 months regarding the magnitude of antibody production, cell proliferation and cytokine profile when compared to immune responses induced in old mice. Therefore, our results corroborate with a promising proposal for prevaccination during childhood and young age, and a booster in older age, to make sure that the primary immunization in early life is not lost in aged individuals. PMID- 29193268 TI - What role does heritability play in transgenerational phenotypic responses to captivity? Implications for managing captive populations. AB - Animals maintained in captivity exhibit rapid changes in phenotypic traits, which may be maladaptive for natural environments. The phenotype can shift away from the wild phenotype via transgenerational effects, with the environment experienced by parents influencing the phenotype and fitness of offspring. There is emerging evidence that controlling transgenerational effects could help mitigate the effects of captivity, improving the success of captively bred animals post release. However, controlling transgenerational effects requires knowledge of the mechanisms driving transgenerational changes. To better understand the genetic mechanisms that contribute to transgenerational effects in captivity we investigated the heritability of behavioral phenotypes using mid parent- and single parent-offspring regressions in a population of captive-reared house mouse (Mus musculus) that we had previously shown exhibit transgenerational changes in boldness and activity behavioral types. Slopes for boldness and activity were all positive, indicating a low to moderate degree of heritability. Though, none of the heritability estimates were statistically significant due to the large surrounding errors. However, the large error surrounding the heritability estimates may also indicate that there is variability in heritability between behavioral traits within the boldness and activity behavioral types. The implication of this finding is that the potential for heritable genetic changes in captivity varies considerably between traits. We conclude that continued investigation of the potential for traits to evolve in captivity is needed to better inform captive breeding and reintroduction programs.

AB - BACKGROUND AND AIM: We investigated the effects of PNPLA3 rs738409, TM6SF2 rs58542926, and MBOAT7-TMC4 rs641738 variants on metabolic phenotypes and their combined effects on the histological severity of non-alcoholic fatty liver disease (NAFLD). METHODS: We genotyped rs738409, rs58542926, and rs641738 in biopsy-proven NAFLD patients (n = 416) and healthy controls (n = 109). Homeostasis model assessment of insulin resistance and adipose tissue insulin resistance were calculated. RESULTS: The rs738409 and rs58542926 variants, but not rs641738, were associated not only with non-alcoholic steatohepatitis (NASH) (odds ratio [OR], 2.00; 95% confidence interval [CI], 1.46-2.73 and OR, 1.91; 95% CI, 1.04-3.51) but also with significant fibrosis (>= F2) (OR, 1.53; 95% CI, 1.11 2.11 and OR, 1.88; 95% CI, 1.02-3.46) in NAFLD, even after adjustment for metabolic risk factors. Of both variants, only rs738409 was associated with homeostasis model assessment of insulin resistance and adipose tissue insulin resistance even in healthy controls (P = 0.046 and 0.002, respectively) as well as in the entire study cohort (P = 0.016 and 0.048, respectively). PNPLA3 and TM6SF2 risk variants additively increased the risk of NASH and significant fibrosis (OR per risk allele, 2.03; 95% CI, 1.50-2.73 and 1.61; 95% CI, 1.19 2.17). Even in subjects with low insulin resistance, the risk of NASH or significant fibrosis increased as the number of risk alleles increased (P = 0.008 and 0.020, respectively). CONCLUSIONS: PNPLA3 and TM6SF2 determine the risk of NASH and significant fibrosis, even after adjustment for insulin resistance, and exert an additive effect on NASH and significant fibrosis.

AB - Extracorporeal photopheresis (ECP) is an established therapy for the treatment of graft-versus-host-disease (GVHD) following an allogeneic stem cell transplant. We performed a prospective analysis of patients receiving ECP treatment for GVHD to identify a clinical pathway and resource utilization of this process. The cohort included consecutive allogeneic stem cell recipients with GVHD. ECP was performed using the CELLEX Photopheresis System or the UVAR XTS Photopheresis System (Therakos, Inc, Exton, PA). A clinical pathway was developed and a time and motion study was conducted to define the resource utilization and costs associated with ECP. Patients were treated with either CELLEX (n = 18 procedures) or UVAR (n = 4 procedures). Total time commitment for each procedure for the 2 machines differed. The time for ECP was 117 min (median, range: 91-164 min) using CELLEX and 161 min (median; range: 140-210) using the UVAR-XTS machine. Total costs of each ECP procedure were $3420.50. There is a considerable time commitment of the patient and the clinical staff when employing ECP to treat GVHD. ECP costs are significant considering this is a prolonged therapy continued for several months. With this finalized pathway and costs, we have a standardized clinical pathway for the treatment of GVHD. We are addressing minimizing resource utilization while emphasizing quality care for these patients.

AB - This study was designed to investigate the possible synergism of amlodipine and candesartan on the reduction of blood pressure (BP) in hypertensive rats. The end organ protection was also observed. In acute experiment, spontaneously hypertensive rats (SHRs) were treated with intragastric administration of amlodipine (0.5, 1, 2, 3 mg/kg), candesartan (1, 2, 3, 4, 6, 8 mg/kg), and 14 different combinations to find the possible ratio of synergistic interaction. In two kidneys, one clip (2K1C) rats, the effects of amlodipine (1 mg/kg), canderastan (2 mg/kg) and their combination on BP reduction were also observed. In chronic study, SHRs were treated with amlodipine (1 mg/kg), candesartan (2 mg/kg), and their combination for 5 months. Organ damage evaluation was performed after BP recording. The probability sum test (q test) was used to evaluate the synergistic action. There is a synergistic interaction between amlodipine and candesartan on BP reduction. The optimal dose ratio is 1:2. The synergistic effect was also confirmed by 2K1C hypertensive rats. In chronic study, this combination (1:2) possessed an obvious synergism on the reduction of BP and BP variability (BPV) and protection on end organs. Multiple regression analysis showed that heart and aortic hypertrophy indexes and glomerular damage parameters were positively related to BP and BPV. In conclusion, combination of amlodipine and candesartan exhibited a potent antihypertensive effect and possessed an obvious synergism on BP reduction and organ protection in hypertension. The optimal proportion was 1:2. BP and BPV reduction may both importantly contribute to end organ protection. PMID- 29193273 TI - Activation of caspase-6 and cleavage of caspase-6 substrates is an early event in NMDA receptor-mediated excitotoxicity. AB - Excitotoxicity, due to overstimulation of N-methyl D-aspartate receptors (NMDARs), has a pivotal role in many neurological disorders. However, NMDAR antagonists often cause side effects, and identifying more druggable therapeutic targets for NMDAR excitotoxicity is an important goal. Activation of caspases is a downstream effect of excitotoxicity that may be critically involved in NMDAR mediated cell death. Caspase-6 (casp6) in particular has been shown to play a key role in the pathogenesis of stroke, Huntington disease, and Alzheimer disease. Using N-methyl D-aspartate (NMDA)-induced excitotoxic injuries of primary rat neurons, we demonstrate that there is an early increase in caspase profiles after an excitotoxic event at the level of mRNA, protein, and activity. Casp6 is elevated and activated first, followed by caspase-8 and caspase-3. Similarly, known casp6 substrates huntingtin, as well as novel casp6 substrates serine/threonine kinase 3 and death domain-associated protein, are cleaved in similar temporal patterns post NMDA. On the basis of these data, we propose that casp6 may be an initiator caspase in apoptotic cascades leading to neuronal death after an excitotoxic event and suggest casp6 as a potential therapeutic target for neurological disorders where NMDAR-mediated excitotoxicity has been shown to play a role.

PMID- 29193274 TI - Melatonin therapy reduces the risk of osteoporosis and normalizes bone formation in multiple sclerosis. AB - Multiple sclerosis (MS) is a common autoimmune and neurodegenerative disease of the central nervous system. Serum levels of melatonin decrease in MS patients who are also at risk of osteoporosis. Procalcitonin (proCT) has been reported as a biomarker of systemic inflammation and autoimmune disease; however, its changes in MS patients have not been well explored. This study investigated, using ELISA, the clinical correlation between serum melatonin and proCT in MS patients. We then assessed the effect of melatonin (10 mg/kg) therapy on bone metabolism and osteoporosis in experimental autoimmune encephalomyelitis (EAE) model of MS and in MS patients. Data showed a significant increase (*P < 0.05) in serum levels of proCT in MS patients, inversely correlated (r = -0.945; P = 0.0001) with melatonin levels, compared to healthy participants. On the other hand, melatonin therapy ameliorated EAE severity by significantly decreasing (*P < 0.05) mean clinical scores, compared to control EAE mice. In addition, serum levels of proCT significantly (**P < 0.01) increased in EAE mice, compared to controls, which was significantly (*P < 0.05) reduced by melatonin. Moreover, EAE-induced decrease in 25-hydroxyvitamin D, calcium, and osteocalcin (OCN) in EAE mice, compared to controls, was significantly (*P < 0.05) increased by melatonin. Finally, OCN serum levels were found to be significantly decreased (*P < 0.05) in MS patients, in comparison with controls. Taken together, we suggest that proCT could be used as a diagnostic biomarker in MS patients and that melatonin normalizes bone metabolites in MS. Further clinical and experimental investigations are needed to understand bone metabolism in MS. PMID- 29193276 TI - Review shows that using surfactant a number of times or as a vehicle for budesonide may reduce the risk of bronchopulmonary dysplasia. AB - AIM: Bronchopulmonary dysplasia (BPD) remains the most common respiratory morbidity in immature infants. This review describes the diagnosis of BPD has evolved and summarises the therapeutic approaches that have made it possible to limit the incidence of BPD. METHOD: We reviewed the literature from the first definition of BPD by Northway in 1967 to the surfactant treatment policies that are currently in use, drawing on more than 50 papers up to 2017. RESULTS: Our review showed that improvements in neonatal survival have been associated with an increased risk of severe BPD, significant levels of long-term morbidity and the increased use of healthcare resources. These issues have encouraged researchers to explore potential new treatments that limit the incidence of BPD. Repeated surfactant instillation and the use of surfactant as a vehicle for budesonide are promising strategies for alleviating the burden of chronic lung disease. Ongoing research on surfactant or stem cell therapy may further improve the respiratory prognosis for prematurely born children. CONCLUSION: Considerable research has been carried out into the increase in BPD, which has resulted from improvements in neonatal survival. Key areas of research include repeated surfactant administration, using surfactant as a vehicle for budesonide and stem cell therapy. PMID- 29193278 TI - DNP-enhanced solid-state NMR spectroscopy of active pharmaceutical ingredients. AB - Solid-state NMR spectroscopy has become a valuable tool for the characterization of both pure and formulated active pharmaceutical ingredients (APIs). However, NMR generally suffers from poor sensitivity that often restricts NMR experiments to nuclei with favorable properties, concentrated samples, and acquisition of one dimensional (1D) NMR spectra. Here, we review how dynamic nuclear polarization (DNP) can be applied to routinely enhance the sensitivity of solid-state NMR experiments by one to two orders of magnitude for both pure and formulated APIs. Sample preparation protocols for relayed DNP experiments and experiments on directly doped APIs are detailed. Numerical spin diffusion models illustrate the dependence of relayed DNP enhancements on the relaxation properties and particle size of the solids and can be used for particle size determination when the other factors are known. We then describe the advanced solid-state NMR experiments that have been enabled by DNP and how they provide unique insight into the molecular and macroscopic structure of APIs. For example, with large sensitivity gains provided by DNP, natural isotopic abundance, 13 C-13 C double-quantum single quantum homonuclear correlation NMR spectra of pure APIs can be routinely acquired. DNP also enables solid-state NMR experiments with unreceptive quadrupolar nuclei such as 2 H, 14 N, and 35 Cl that are commonly found in APIs. Applications of DNP-enhanced solid-state NMR spectroscopy for the molecular level characterization of low API load formulations such as commercial tablets and amorphous solid dispersions are described. Future perspectives for DNP-enhanced solid-state NMR experiments on APIs are briefly discussed. PMID- 29193277 TI - Spectrophotometry and Ultracentrifugation for Measurement of Plasma Lipids in Dogs with Diabetes Mellitus. AB - BACKGROUND: There are conflicting reports of plasma lipoprotein lipid content in dogs with diabetes mellitus (DM). OBJECTIVES: To determine lipoprotein lipid content of plasma of dogs with DM by spectrophotometry and ultracentrifugation; to compare lipoprotein lipid content in diabetic and healthy dogs; and to quantify apolipoprotein B-100 (ApoB) in dogs with DM. ANIMALS: 22 dogs with DM and 9 healthy dogs. METHODS: Cross-sectional study. Triglyceride (TG), total cholesterol (TC), and high-density lipoprotein cholesterol (HDL-C) concentrations were measured by spectrophotometry. Very low-density lipoprotein cholesterol (VLDL-C) and low-density lipoprotein cholesterol (LDL-C) concentrations were calculated after ultracentrifugation. Non-HDL-C cholesterol was calculated by subtracting HDL-C from TC. ApoB was quantified by ELISA. The Mann-Whitney test was used for comparison of median lipoprotein concentrations, and Spearman's correlation was used to assess associations between ApoB and lipoprotein fractions. RESULTS: All values are reported in mg/dL. Median TG (122), TC (343.5), HDL-C, (200), VLDL-C, (27) LDL-C (68), non-HDL-C (114), and ApoB (320) were significantly higher in dogs with DM, compared to healthy dogs (57, 197, 168, 12, 16, 31, and 258, respectively, P-values 0.0079, <0.001, 0.029, 0.011, <0.001, <0.001, 0.025, respectively). A significant association was found between ApoB and LDL-C (Spearman's rho = 0.41, P = 0.022) and between ApoB and non-HDL-C (Spearman's rho = 0.40, P = 0.027). CONCLUSIONS AND CLINICAL IMPORTANCE: Dyslipidemia of dogs with DM is characterized by pronounced increases in LDL-C and non-HDL-C concentrations, although all lipoprotein fractions are significantly increased. Knowledge of specific lipoprotein fraction alterations in dogs with DM can enhance treatment options for diabetic dyslipidemia in dogs. PMID- 29193279 TI - Numerical and Experimental Evaluation of High-Intensity Focused Ultrasound Induced Lesions in Liver Tissue Ex Vivo. AB - OBJECTIVES: Recent advances in the field of acoustics and piezoelectric and ultrasound transducers have led to new approaches to the diagnosis and treatment of certain diseases. One method of treatment with ultrasonic waves is high intensity focused ultrasound (HIFU) treatment, which is a thermal therapeutic method used to treat malignant tumors. Although a variety of treatment-planning strategies using ultrasonic waves have been investigated, little clinical success has been achieved. Computational modeling is a powerful tool for predicting device performance. METHODS: The heating induced by a concave transducer with operating powers of 85 and 135 W was studied, and the experimental results presented in this article verify its applicability. Numerical simulations of the nonlinear acoustic field were performed by using the Westervelt and Khokhlov Zabolotskaya-Kuznetsov equations. Heat transfer was measured for the 2 operational powers, and the results were compared with ex vivo experimental results. In addition, thermal dose contours for both the simulation and experimental results were calculated to investigate the ablated area. RESULTS: Good agreement was found between the experimental and numerical results. The results show that the average temperature deviations calculated at the focal point were 12.8% and 4.3% for transducer powers of 85 and 135 W, respectively. CONCLUSIONS: This study provides guidance to HIFU practitioners in determining lesion size and identifying nonlinear effects that should be considered in HIFU procedures. PMID- 29193280 TI - Novel endoscopic categorization for prediction of chemoradiotherapy response in locally advanced esophageal cancer. AB - BACKGROUND AND AIM: Preoperative chemoradiotherapy (CRT) followed by esophagectomy is a well-known treatment modality for patients with locally advanced esophageal cancer (EC). This study developed an algorithm to predict pathological complete response (CR) in these patients using post-CRT endoscopic category with biopsy and validated the proposed algorithm. METHODS: A retrospective review of 141 consecutive patients who completed preoperative CRT and underwent surgical resection for locally advanced EC was performed. The post CRT endoscopic findings of each patient were stratified into five categories. RESULTS: The distribution of post-CRT endoscopic categories was significantly different between the pathological CR and non-pathological CR groups (P < 0.001). About 76.8% (73/95) of patients in category 0, 1, or 2 achieved pathological CR. In contrast, 91.3% (42/46) of endoscopic categories 3 and 4 patients did not achieve pathological CR. Sensitivity of post-CRT biopsy was 11.1%. Therefore, an algorithm combining biopsy results and dichotomized post-CRT endoscopic category (category 0, 1, or 2 vs category 3 or 4) was developed. The sensitivity, specificity, and accuracy in predicting pathological CR by the proposed algorithm were 64.8%, 95.9%, and 82.8%, respectively. In the multivariate analysis, the proposed algorithm remained a significant negative factor of survival (P < 0.001). CONCLUSIONS: Algorithm using post-CRT endoscopic category with biopsy may help identify locally advanced EC patients who achieved pathological CR after preoperative CRT. Modalities to accurately detect subepithelial remnant EC may further aid in predicting pathological CR. PMID- 29193281 TI - A randomised trial of enteral glutamine supplementation for very preterm children showed no beneficial or adverse long-term neurodevelopmental outcomes. AB - AIM: This study evaluated the long-term effects of enteral glutamine supplementation on neurodevelopmental outcomes of a Dutch cohort of very preterm children at 13 years of age. METHODS: The cohort was enrolled in a randomised placebo-controlled trial between 2001 and 2003 in which infants received glutamine- or alanine-supplemented enteral nutrition during the first month of life. Participants were invited for follow-up at a mean age of 13.30 years. Motor, neurocognitive, academic and behavioural outcomes were assessed in 61 children. RESULTS: No differences were found between the groups regarding motor, intellectual, academic and behavioural functioning. Forward span visuospatial working memory performance was better in the controls (crude/adjusted model: d = 0.67/0.64, p = 0.02/0.02), but no difference was found for backward span. After the data were adjusted for confounders, the groups differed regarding parent rated attention (crude/adjusted model: d = 0.47/0.73, p = 0.07/0.003), but both groups scored within the normal range. CONCLUSION: This was the first study on the long-term effects of enteral glutamine supplementation on the neurodevelopmental outcomes of very preterm children. Our study provided no evidence that enteral glutamine supplementation had any beneficial or adverse effects on the children's motor, neurocognitive, academic and behavioural outcomes at 13 years of age. PMID- 29193282 TI - A hot-water extract of Sanguisorba officinalis ameliorates endotoxin-induced septic shock by inhibiting inflammasome activation. AB - The inflammasome is a multiprotein signaling complex that mediates inflammatory innate immune responses through caspase 1 activation and subsequent IL-1beta secretion. However, because its aberrant activation often leads to inflammatory diseases, targeting the inflammasome holds promise for the treatment of inflammation-related diseases. In this study, it was found that a hot-water extract of Sanguisorba officinalis (HSO) suppresses inflammasome activation triggered by adenosine 5'-triphosphate, nigericin, microbial pathogens, and double stranded DNA in bone marrow-derived macrophages. HSO was found to significantly suppress IL-1beta production in a dose-dependent manner; this effect correlated well with small amounts of caspase 1 and little ASC pyroptosome formation in HSO-treated cells. The anti-inflammatory activity of HSO was further confirmed in a mouse model of endotoxin-induced septic shock. Oral administration of HSO reduced IL-1beta titers in the serum and peritoneal cavity, increasing the survival rate. Taken together, our results suggest that HSO is an inhibits inflammasome activation through nucleotide-binding domain and leucine-rich repeat pyrin domain 3, nucleotide-binding domain and leucine-rich repeat caspase recruitment domain 4 and absent in melanoma 2 pathways, and may be useful for treatment of inflammasome-mediated diseases. PMID- 29193283 TI - Diastolic dysfunction in pulmonary artery hypertension: Creatine kinase and the potential therapeutic benefit of beta-blockers. AB - Passive properties of the myocardium influence diastolic filling and cardiac output. In heart failure, changes in contributors to the passive properties of the ventricle, such as titin and collagen, and loss of the metabolic enzyme creatine kinase, increase resistance to filling resulting in diastolic dysfunction. Pulmonary artery hypertension (PAH) arises from interactions between the pulmonary vasculature and the right ventricle (RV) which ultimately leads to RV failure. Beta1-adrenergic receptor blockers (BB) act on the myocardium and are beneficial in left heart failure but are not used in PAH. We investigated whether BB improved survival and RV function in a rat model of PAH. Rats were injected with monocrotaline (60 mg/kg) to induce PAH and RV failure, or saline as controls (CON). When PAH was established, rats were treated with metoprolol (10 mg/kg per day) (MCT+BB) or vehicle (sucrose) (MCT); CON were treated with vehicle. In vivo measurement of RV compliance using pressure-volume catheter, indicated diastolic dysfunction in the RV of MCT rats was improved with BB treatment. Expression of creatine kinase protein and mRNA was lower in MCT rats compared to CON, with a trend for reversion by BB treatment. Isolated CON RV myocytes had a positive contraction response to faster pacing, whereas it was negative in MCT. MCT+BB cells had an intermediate response, indicating improved ability to respond to increased demand. BB improved diastolic function, partially restored metabolic enzymes and augmented contractility in PAH. These data support the hypothesis that BB may be beneficial in PAH by supporting RV function. PMID- 29193285 TI - Bioaccumulation, uptake, and toxicity of carbamazepine in soil-plant systems. AB - Since the detection of active pharmaceutical ingredients (APIs) in various environmental media, research has explored the potential uptake and toxicity of these chemicals to species inhabiting these matrices. Specifically, pharmaceuticals, including the antiepileptic API carbamazepine (CBZ), are taken up from soil by a range of plants. Many short-term studies have also suggested that certain APIs induce toxicity in plants. However, the effects of APIs on fruiting plants remain relatively unexplored. The present study investigated the uptake, bioaccumulation, and toxicity of CBZ in Cucurbita pepo (zucchini) from seed to full maturity across a range of CBZ exposure concentrations in soil (0.1 20 mg/kg). Results of biomass, chlorophyll, starch and total nitrogen (N) concentration in C. pepo indicated toxicity at soil concentrations of >=10 mg/kg. There were clear visual indications of increasing toxicity on leaves, including chlorosis and necrosis, from soil concentrations of 1 up to 20 mg/kg. The present study also revealed novel insights into the effect of CBZ accumulation on C. pepo fruiting: female C. pepo flowers were unable to set fruit when leaf concentrations were >=14 mg/kg. These findings may have implications for future agricultural productivity in areas where reclaimed wastewater containing APIs is a source of irrigation. Detectable CBZ concentrations were found in edible C. pepo fruit, indicating the possibility of trophic transfer. Environ Toxicol Chem 2018;37:1122-1130. (c) 2017 SETAC. PMID- 29193284 TI - Drug burden index to define the burden of medicines in older adults with intellectual disabilities: An observational cross-sectional study. AB - AIMS: The drug burden index (DBI) is a dose-related measure of anticholinergic and sedative drug exposure. This cross-sectional study described DBI in older adults with intellectual disabilities (ID) and the most frequently reported therapeutic classes contributing to DBI and examined associations between higher DBI scores and potential adverse effects as well as physical function. METHODS: This study analysed data from Wave 2 (2013/2014) of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA), a representative study on the ageing of people with ID in Ireland. Self- and objectively-reported data were collected on medication use and physical health, including health conditions. The Barthel index was the physical function measure. RESULTS: The study examined 677 individuals with ID, of whom 644 (95.1%) reported taking medication and 78.6% (n = 532) were exposed to medication with anticholinergic and/or sedative activity. 54.2% (n = 367) were exposed to high DBI score (>=1). Adjusted multivariate regression analysis revealed no significant association between DBI score and daytime dozing, constipation or falls. After adjusting for confounders (sex, age, level of ID, comorbidities, behaviours that challenge, history of falls), DBI was associated with significantly higher dependence in the Barthel index (P = 0.002). CONCLUSIONS: This is the first time DBI has been described in older adults with ID. Scores were much higher than those observed in the general population and higher scores were associated with higher dependence in Barthel index activities of daily living. PMID- 29193286 TI - Understanding ED performance after the implementation of activity-based funding. AB - OBJECTIVE: The aim of this study was to describe emergency department (ED) activities and staffing after the introduction of activity-based funding (ABF) to highlight the challenges of new funding arrangements and their implementation. METHODS: A retrospective study of public hospital EDs in Queensland, Australia, was undertaken for 2013-2014. The ED and hospital characteristics are described to evaluate the alignment between activity and resourcing levels and their impact on performance. RESULTS: Twenty EDs participated (74% response rate). Weighted activity units (WAUs) and nursing staff varied based on hospital type and size. Larger hospital EDs had on average 9076 WAUs and 13 full time equivalent (FTE) nursing staff per 1000 WAUs; smaller EDs had on average 4587 WAUs and 10.3 FTE nursing staff per 1000 WAUs. Medical staff was relatively consistent (8.1-8.7 FTE per 1000 WAUs). The proportion of patients admitted, discharged, or transferred within 4 hours ranged from 73% to 79%. The ED medical and nursing staffing numbers did not correlate with the 4-hour performance. CONCLUSION: Substantial variation exists across Queensland EDs when resourcing service delivery in an activity-based funding environment. Historical inequity persists in the staffing profiles for regional and outer metropolitan departments. The lack of association between resourcing and performance metrics provides opportunity for further investigation of efficient models of care. PMID- 29193287 TI - Sensitivity enhancement for detection of hyperpolarized 13 C MRI probes with 1 H spin coupling introduced by enzymatic transformation in vivo. AB - PURPOSE: Although 1 H spin coupling is generally avoided in probes for hyperpolarized (HP) 13 C MRI, enzymatic transformations of biological interest can introduce large 13 C-1 H couplings in vivo. The purpose of this study was to develop and investigate the application of 1 H decoupling for enhancing the sensitivity for detection of affected HP 13 C metabolic products. METHODS: A standalone 1 H decoupler system and custom concentric 13 C/1 H paddle coil setup were integrated with a clinical 3T MRI scanner for in vivo 13 C MR studies using HP [2-13 C]dihydroxyacetone, a novel sensor of hepatic energy status. Major 13 C 1 H coupling JCH = ~150 Hz) is introduced after adenosine triphosphate-dependent enzymatic transformation of HP [2-13 C]dihydroxyacetone to [2-13 C]glycerol-3 phosphate in vivo. Application of WALTZ-16 1 H decoupling for elimination of large 13 C-1 H couplings was first tested in thermally polarized glycerol phantoms and then for in vivo HP MR studies in three rats, scanned both with and without decoupling. RESULTS: As configured, 1 H-decoupled 13 C MR of thermally polarized glycerol and the HP metabolic product [2-13 C]glycerol-3-phosphate was achieved at forward power of approximately 15 W. High-quality 3-s dynamic in vivo HP 13 C MR scans were acquired with decoupling duty cycle of 5%. Application of 1 H decoupling resulted in sensitivity enhancement of 1.7-fold for detection of metabolic conversion of [2-13 C]dihydroxyacetone to HP [2-13 C]glycerol-3 phosphate in vivo. CONCLUSIONS: Application of 1 H decoupling provides significant sensitivity enhancement for detection of HP 13 C metabolic products with large 1 H spin couplings, and is therefore expected to be useful for preclinical and potentially clinical HP 13 C MR studies.

PMID- 29193289 TI - Disproportionate Mental Health Burden Associated With Past-Year Intimate Partner Violence Among Women Receiving Care in the Veterans Health Administration. AB - Experience of intimate partner violence (IPV) can lead to mental health conditions, including anxiety, depression, and unhealthy substance use. Women seen in the Veterans Health Administration (VHA) face high rates of both IPV and mental health morbidity. This study aimed to identify associations between recent IPV experience and mental health diagnoses among women VHA patients. We examined medical records data for 8,888 female veteran and nonveteran VHA patients across 13 VHA facilities who were screened for past-year IPV between April, 2014 and April, 2016. Compared with women who screened negative for past-year IPV (IPV-), those who screened positive (IPV+; 8.7%) were more than twice as likely to have a mental health diagnosis, adjusted odds ratio (AOR) = 2.27, 95% confidence interval (CI) [1.95, 2.64]; or more than two mental health diagnoses, AOR = 2.29, 95% CI [1.93, 2.72]). Screening IPV+ was also associated with significantly higher odds of each type of mental health morbidity (AOR range = 1.85-3.19) except psychoses. Over half (53.5%) of the women who screened IPV+ had a mental health diagnosis, compared with fewer than one-third (32.6%) of those who screened IPV-. Each subtype of IPV (psychological, physical, and sexual violence) was significantly associated with having a mental health diagnosis (AOR range = 2.25-2.37) or comorbidity (AOR range = 2.17-2.78). Associations remained when adjusting for military sexual trauma and combat trauma among the veteran subsample. These findings highlight the mental health burden associated with past year IPV among female VHA patients and underscore the need to address psychological and sexual IPV, in addition to physical violence. PMID- 29193288 TI - Characterization of tumor vascular permeability using natural dextrans and CEST MRI. AB - PURPOSE: To investigate the use of natural dextrans as nano-sized chemical exchange saturation transfer (CEST) MRI probes for characterizing size-dependent tumor vascular permeability. METHODS: Dextrans of different molecular weight (10, 70, 150, and 2000 kD) were characterized for their CEST contrast. Mice (N = 5) bearing CT26 subcutaneous colon tumors were injected intravenously with 10 kD (D10, 6 nm) and 70 kD (D70, 12 nm) dextran at a dose of 375 mg/kg. The CEST-MRI signal in the tumors was assessed before and approximately 40 min after each injection using a dynamic CEST imaging scheme. RESULTS: All dextrans of different molecular weights have a strong CEST signal with an apparent maximum of approximately 0.9 ppm. The detectability and effects of pH and saturation conditions (B1 and Tsat ) were investigated. When applied to CT26 tumors, the injection of D10 could produce a significant "dexCEST" enhancement in the majority of the tumor area, whereas the injection of D70 only resulted in an increase in the tumor periphery. Quantitative analysis revealed the differential permeability of CT26 tumors to different size particles, which was validated by fluorescence imaging and immunohistochemistry. CONCLUSIONS: As a first application, we used 10- and 70-kD dextrans to visualize the spatially variable, size-dependent permeability in the tumor, indicating that nano-sized dextrans can be used for characterizing tumor vascular permeability with dexCEST MRI and, potentially, for developing dextran-based theranostic drug delivery systems.

PMID- 29193290 TI - The 1st step initiation essential for allergen-specific IgE antibody production upon the 2nd step: Induction of non-specific IgE+ small B cells containing secondly-sensitized allergen-specific ones in mice firstly-sensitized with an allergen. AB - There was a significant amount of non-specific, but not of allergen (e.g., papain, mite feces and four kinds of pollen)-specific, IgE antibodies (Abs) in the sera of normal mice. An i.n. injection of each allergen without adjuvant into mice caused an increase in total IgE Ab titers with a similar time course in the serum. However, the stage of initiation of allergy varied from allergen to allergen. Submandibular lymph node cells from normal mice contained papain-, but not mite feces- or pollen-specific IgE+ cells and an i.n. injection of papain induced papain-specific IgE Abs in the serum. In contrast, one (i.n.) or two (i.n. and s.c) injections of mite feces induced neither mite feces-specific IgE+ cells in the lymph nodes nor mite feces-specific IgE Abs in the serum. I.n. sensitization with cedar pollen induced cedar pollen-specific IgE+ small B cells in the lymph nodes on Day 10, when non-specific IgE Ab titers reached a peak in the serum, implying induction of related allergen-specific IgE+ small cells as well. In fact, a second (s.c.) injection of ragweed (or cedar) pollen into mice sensitized i.n. once with cedar (or ragweed) pollen, but not with mite feces, induced a large amount of ragweed (or cedar) pollen-specific IgE Abs in the serum. These results indicate that when firstly-sensitized non-specific IgE+ small B cells in mouse lymph nodes include some secondly-sensitized allergen specific ones, mice produce IgE Abs specific for the secondly-injected allergen. PMID- 29193291 TI - Validity and reliability of a Portuguese version of the Summated Xerostomia Inventory-5. AB - OBJECTIVES: The aim of this study was to validate and determine the reliability of the Portuguese version of the Summated Xerostomia Inventory. BACKGROUND: Many conditions such as head and neck radiation, autoimmune diseases or polypharmacy are characterised by hyposalivation which can affect oral and systemic quality of life. As such, this condition must be assessed, and the English version of the Xerostomia Inventory has been increasingly used to determine the severity of dry mouth perception. MATERIALS AND METHODS: This was a descriptive cross-sectional study, which employed volunteers suffering from hyposalivation after local ethical committee clearance. Each patient signed an informed consent and responded to the Portuguese version of the questionnaire in the form of an interview. This was repeated again after 2 weeks. A standard single question provided a validity check. Data were analysed using Cronbach's alpha to test its reliability and total and interitem correlation, and intraclass correlation to determine its internal consistency and test-retest reliability. Significance was set at .05. RESULTS: A sample of 103 volunteers was recruited. Cronbach's alpha was .84 and .87 for the first and second test administrations, respectively. The intraclass correlation coefficient value for the test-retest reliability was .93, and scores for the individual items ranged from .79 to .90. The correlation between the total score of the questionnaire and standard single dry mouth question was .66, indicating a very good correlation. CONCLUSION: Demonstrating excellent psychometric properties, the Summated Xerostomia Inventory (Portuguese Version) is a valid tool for quantifying Xerostomia in a dry mouth-afflicted population. PMID- 29193292 TI - A multispecies test of source-sink indicators to prioritize habitat for declining populations. AB - For species at risk of decline or extinction in source-sink systems, sources are an obvious target for habitat protection actions. However, the way in which source habitats are identified and prioritized can reduce the effectiveness of conservation actions. Although sources and sinks are conceptually defined using both demographic and movement criteria, simplifications are often required in systems with limited data. To assess the conservation outcomes of alternative source metrics and resulting prioritizations, we simulated population dynamics and extinction risk for 3 endangered species. Using empirically based habitat population models, we linked habitat maps with measured site- or habitat-specific demographic conditions, movement abilities, and behaviors. We calculated source sink metrics over a range of periods of data collection and prioritized consistently high-output sources for conservation. We then tested whether prioritized patches identified the habitats that most affected persistence by removing them and measuring the population response. Conservation decisions based on different source-sink metrics and durations of data collection affected species persistence. Shorter time series obscured the ability of metrics to identify influential habitats, particularly in temporally variable and slowly declining populations. Data-rich source-sink metrics that included both demography and movement information did not always identify the habitats with the greatest influence on extinction risk. In some declining populations, patch abundance better predicted influential habitats for short-term regional persistence. Because source-sink metrics (i.e., births minus deaths; births and immigrations minus deaths and emigration) describe net population conditions and cancel out gross population counts, they may not adequately identify influential habitats in declining populations. For many nonequilibrium populations, new metrics that maintain the counts of individual births, deaths, and movement may provide additional insight into habitats that most influence persistence.

AB - Several studies have shown the relationship between symptoms of posttraumatic stress disorder (PTSD), somatic symptoms, and the mediating effect of depression and anxiety. The following study was conducted to investigate the relationship between PTSD symptoms and somatic complaints through underlying symptoms of depression and anxiety. The participants of the study were 2,799 veterans who were examined after a 6-month deployment. They were assessed using the PTSD Checklist (PCL-5) and Patient Health Questionnaire (PHQ) for depression, anxiety, and somatic complaints. To check the indirect effect of PTSD on somatic complaints through depression and anxiety, mediation model 4 (parallel mediation) of the SPSS PROCESS macro was used. There was a significant total indirect effect of PTSD through depression and anxiety on somatic complaints, b = 0.14, 95% confidence interval (CI) [0.12, 0.16], from which an indirect effect of PTSD on somatic complaints through depression was b = 0.08, 95% CI [0.06, 0.10], and through anxiety it equaled b = 0.06, 95% CI [0.04, 0.07]. The ratio of indirect to total effect was 0.66, 95% CI [0.59, 0.75]. The present study helps us to understand the role of depression and anxiety symptoms when the symptoms of PTSD and somatic complaints are present. These new findings may have implications for the management as well as treatment of PTSD because they recognize the importance of symptoms of anxiety and depression when somatic complaints are present.

AB - Recent evidence suggests that the oral drug Fingolimod (FTY720) for relapsing remitting multiple sclerosis (MS) may act directly on the central nervous system (CNS) and modulate disease pathogenesis and progression in experimental models of MS. However, the specific subtype of sphingosine-1-phosphate (S1P) receptors that mediates the effect of FTY720 on the CNS cells has not been fully elucidated. Here, we report that S1P receptor 1 (S1PR1) is elevated in reactive astrocytes in an autoimmunity independent mouse model of MS and that selective S1PR1 modulation is sufficient to ameliorate the loss of oligodendrocytes and demyelination. The non-selective S1PR modulator, FTY720, or a short-lived S1PR1-specific modulator, CYM5442, was administered daily to mice while on cuprizone diet. Both FTY720- and CYM5422-treated mice displayed a significant reduction in oligodendrocyte apoptosis and astrocyte and microglial activation in comparison to vehicle treated groups, which was associated with decreased production of proinflammatory mediators and down-regulation of astrocytic S1PR1 protein. Interestingly, S1PR1 modulation during the early phase of cuprizone intoxication was required to suppress oligodendrocyte death and consequent demyelination as drug treatment from 10 days after the initiation of cuprizone feeding was no longer effective. CYM5442 treatment during the brief cuprizone exposure significantly prevented Il 1beta, Il-6, Cxcl10, and Cxcl3 induction, resulting in suppression of subsequent reactive gliosis and demyelination. Our study identifies functional antagonism of S1PR1 as a major mechanism for the protective effect of FTY720 in the cuprizone model and suggests pathogenic contributions of astrocyte S1PR1 signaling in primary demyelination and its potential as a therapeutic target for CNS inflammation.

PMID- 29193298 TI - What Aspects of Rural Life Contribute to Rural-Urban Health Disparities in Older Adults? Evidence From a National Survey. AB - PURPOSE: Rural-urban health disparities are well-documented and particularly problematic for older adults. However, determining which specific aspects of rural or urban living initiate these disparities remains unclear. The purpose of this study was to assess associations between place-based characteristics of rural-urban status and health among adults age 65+. METHODS: Data from the 2012 Behavioral Risk Factor Surveillance System were geographically linked to place based characteristics from the American Community Survey. Self-reported health (SRH), obesity, and health checkup within the last year were modeled against rural-urban status (distance to nearest metropolitan area, population size, population density, percent urban, Urban Influence Codes [UIC], Rural-Urban Continuum Codes [RUCC], and Rural-Urban Commuting Area [RUCA]) using generalized linear models, accounting for covariates and complex sampling, overall, and stratified by area-level income. FINDINGS: In general, increasing urbanicity was associated with a reduction in negative SRH for all 7 measures of rural-urban status. For low-income counties, this association held for all measures and characteristics of rural-urban status except population density. However, for high-income counties, the association was reversed-respondents living in areas of increasing urbanicity were more likely to report negative SRH for 4 of the 7 measures (RUCC, UIC, RUCA, and percent urban). Findings were mixed for the outcome of obesity, where rural areas had higher levels, except in low-income counties, where the association between rurality and obesity was reversed (OR 1.033, 95%CI: 1.002-1.064). CONCLUSION: These results suggest that rural-urban status is both a continuum and multidimensional. Distinct elements of rural-urban status may influence health in nuanced ways that require additional exploration in future studies. PMID- 29193299 TI - Improved parallel image reconstruction using feature refinement. AB - PURPOSE: The aim of this study was to develop a novel feature refinement MR reconstruction method from highly undersampled multichannel acquisitions for improving the image quality and preserve more detail information. THEORY AND METHODS: The feature refinement technique, which uses a feature descriptor to pick up useful features from residual image discarded by sparsity constrains, is applied to preserve the details of the image in compressed sensing and parallel imaging in MRI (CS-pMRI). The texture descriptor and structure descriptor recognizing different types of features are required for forming the feature descriptor. Feasibility of the feature refinement was validated using three different multicoil reconstruction methods on in vivo data. RESULTS: Experimental results show that reconstruction methods with feature refinement improve the quality of reconstructed image and restore the image details more accurately than the original methods, which is also verified by the lower values of the root mean square error and high frequency error norm. CONCLUSION: A simple and effective way to preserve more useful detailed information in CS-pMRI is proposed. This technique can effectively improve the reconstruction quality and has superior performance in terms of detail preservation compared with the original version without feature refinement.

AB - The green rice leafhopper, Nephotettix cincticeps, is a major rice pest in Southeast Asia and Southern China. Novel control strategies must be explored to control the rice pest. Behavior or fitness regulation of insect by modulating the Troponin C (TnC) may be a novel strategy in the comprehensive management of the insect pest. However, characterizations and functions of TnC, especially regarding effect of its RNA interference-mediated gene knockdown on the behavior or fitness of N. cincticeps remain unknown. Here, we successfully cloned and characterized TnC gene from N. cincticeps (Nc-TnC). We demonstrated that Nc-TnC ubiquitously transcribed at all development stages and special tissues in adult insects, with relative higher levels at the adult stage and in the intestinal canal. Microinjection- or oral membrane feeding-based transient knockdown of Nc TnC adversely affected the performance or fitness, such as the decreased survival, feeding capacity, weight, and fecundity of N. cincticeps. Furthermore, we revealed that the expression of Nc-TnC was suppressed by its interaction with rice dwarf virus-encoded nonstructural protein 10, which ultimately affected detrimentally the corresponding parameters of the performance or fitness of N. cincticeps. In conclusion, our data deepen understanding of Nc-TnC functions during the development of and viral infection in N. cincticeps. It imply Nc-TnC may serve as a potential target for N. cincticeps control in future. PMID- 29193301 TI - Exposure to human voices has beneficial effects on preterm infants in the neonatal intensive care unit. AB - : We reviewed the literature up to March 2016 on the effects of nonmaternal voices on preterm infants' clinical outcomes. Of the 11 studies that met the inclusion criteria, 10 focused on short-term outcomes and one looked at long-term effects. The studies mainly showed that vocal stimuli increased preterm infants' stability in terms of heart rate, respiratory rate, oxygen saturation and behavioural measures. Improvements in feeding skills were also reported. The methods and the measures used in the studies were heterogeneous, making it difficult to draw reliable conclusions. CONCLUSION: Vocal stimuli increased preterm infants' stability, but further studies are needed. PMID- 29193302 TI - Enteroendocrine and adipokine associations with type 2 diabetes: Phenotypic risk scoring approaches. AB - BACKGROUND AND AIM: The contribution of gut-derived factors to the mechanisms linking obesity and metabolic disease remains under-investigated. The aim of the current study was to examine the associations between glucagon and enteroendocrine signaling and type 2 diabetes (T2D) using a derived risk score approach. To compare the relative importance of the enteroendocrine system, associations between adipokine measures and T2D were also investigated. METHODS: A total of 130 individuals with T2D and 161 individuals without T2D were included in the study. Circulating concentrations of enteroendocrine (glucagon, ghrelin, glucagon-like peptide-1, and gastric inhibitory peptide) and adipokine mediators (adiponectin, leptin, resistin, visfatin, and adipsin) were measured. Standard scores (Z-scores) were determined for each measure and enteroendocrine risk scores (ERS) and adipokine risk scores (ARS) calculated based on summation of the component measures. Associations between both the ERS and ARS and T2D status were assessed using logistic regression models. RESULTS: The ERS was significantly associated with T2D status in an adjusted model (odds ratio: 1.36; 95% confidence interval [CI]: 1.08-1.72; P = 0.009). Associations between the ARS and T2D status were not independent of age, sex, and body mass index (odds ratio: 1.21; 95%CI: 0.99-1.47; P = 0.06). Quantification of risk across ERS tertiles revealed that individuals with an ERS in the upper tertile were 10 times more likely (CI: 3.23 32.73; P < 0.001) to have T2D. CONCLUSIONS: These data support an association between enteroendocrine signaling and T2D. Use of the ERS as a potential tool for classifying individuals with metabolic syndrome as high or low risk for T2D development is being considered. PMID- 29193303 TI - Diagnosis, treatment and outcome of cranial nuchal bursitis in 30 horses. AB - BACKGROUND: No large retrospective case series describing the treatment and outcomes following diagnosis of cranial nuchal bursitis have been published. OBJECTIVE: To describe the clinical presentation, diagnostic techniques, treatment and outcome of horses suffering from cranial nuchal bursitis and to determine their outcome after medical or surgical treatment. STUDY DESIGN: Retrospective case series. METHODS: Medical records (1990-2014) of two referral centres were reviewed for signalment, diagnostic features, method of treatment (medical, surgical or both) and outcome. RESULTS: The median age of horses was 13 years (range 5-22 years) and follow-up time ranged from 12 to 108 months. Fourteen horses were treated medically and 20 horses were treated surgically. Of those horses treated medically, four horses had recurrence of clinical signs requiring subsequent surgical treatment. Overall, 41.7% of horses had recurrence of clinical signs following treatment and 66.7% of horses were able to return to their previous level of exercise. Five horses underwent more than one surgical procedure due to recurrence of clinical signs. Of those horses treated solely surgically, 28.6% of the horses had recurrence of clinical signs and 78.6% returned to their previous level of exercise. Of those horses treated solely medically, 33.3% had recurrence of clinical signs and 66.7% returned to their previous level of exercise. Of those horses treated surgically following failed medical management, 100% had recurrence of clinical signs and 25% returned to their previous level of exercise. MAIN LIMITATIONS: Retrospective design with small sample number. CONCLUSIONS: Nuchal bursitis can be successfully managed with either medical or surgical treatment. Prognosis for return to work tends to be worse in horses requiring surgical intervention following failed medical management. PMID- 29193304 TI - Microbial colonization of the periodontal pocket and its significance for periodontal therapy. AB - The aim of this paper was to evaluate strategies for periodontal therapy from the perspective of periodontal disease being a consequence of microbial colonization of the periodontal pocket environment. In classic bacterial infections the diversity of the microbiota decreases as the disease develops. In most cases of periodontitis, however, the diversity of the flora increases. Most incriminating bacteria are thought to harm tissues significantly only if present in high numbers over prolonged periods of time. Clinical trials have repeatedly demonstrated that scaling and root planing, a procedure that aims to remove subgingival bacterial deposits by scraping on the tooth surface within the periodontal pocket, is effective. At present, for the therapy of any form of periodontal disease, there exists no protocol with proven superiority, in terms of efficiency or effectiveness, over scaling and root planing plus systemic amoxicillin and metronidazole. Some exponents advocate rationing these drugs for patients with a specific microbial profile. However, the evidence for any benefit of bacteriology-assisted clinical protocols is unsatisfactory. Treated sites are subject to recolonization with a microbiota similar to that present before therapy. The degree and speed of recolonization depends on the treatment protocol, the distribution patterns of periodontal microorganisms elsewhere in the oral cavity and the quality of the patient's oral hygiene. To limit the use of antibiotics and to avoid accumulation of harmful effects by repeated therapy, further efforts must be made to optimize procedures addressing the microbial colonization and recolonization of the periodontal pocket. PMID- 29193305 TI - The genetically determined production of the alarmin eosinophil-derived neurotoxin is reduced in visceral leishmaniasis. AB - Visceral leishmaniasis (VL) is the most severe form of leishmaniasis. Recent findings indicate that dendritic cells have a key role in the defense against the Leishmania parasite and that the activity of this cell may be modified by the eosinophil secretory protein eosinophil-derived neurotoxin (EDN). We hypothesized that the interactions between dendritic cells and EDN might be of importance in the disease development. Cellular content of EDN was analyzed by ELISA. The single-nucleotide polymorphisms at positions 405, 416, and 1122 in the EDN gene were analyzed by real-time PCR with TaqMan(r) reagents. The study cohorts comprised 239 Sudanese subjects (65 healthy controls and 174 with VL) and 300 healthy Swedish controls. The eosinophil content of EDN was lower in VL as compared with controls (p < 0.0001). The EDN405 (G>C) genotype distribution was similar among Swedish and Sudanese controls, whereas VL subjects had a higher prevalence of the EDN405-GG genotype (p < 0.0001). The content of EDN in the eosinophils was closely linked to the EDN405 polymorphism (p = 0.0002). Our findings suggest that the predisposition to acquire VL is related to the genetic polymorphism of the EDN gene and the reduced production by the eosinophil of this gene product. PMID- 29193306 TI - Artificial neural networks for stiffness estimation in magnetic resonance elastography. AB - PURPOSE: To investigate the feasibility of using artificial neural networks to estimate stiffness from MR elastography (MRE) data. METHODS: Artificial neural networks were fit using model-based training patterns to estimate stiffness from images of displacement using a patch size of ~1 cm in each dimension. These neural network inversions (NNIs) were then evaluated in a set of simulation experiments designed to investigate the effects of wave interference and noise on NNI accuracy. NNI was also tested in vivo, comparing NNI results against currently used methods. RESULTS: In 4 simulation experiments, NNI performed as well or better than direct inversion (DI) for predicting the known stiffness of the data. Summary NNI results were also shown to be significantly correlated with DI results in the liver (R2 = 0.974) and in the brain (R2 = 0.915), and also correlated with established biological effects including fibrosis stage in the liver and age in the brain. Finally, repeatability error was lower in the brain using NNI compared to DI, and voxel-wise modeling using NNI stiffness maps detected larger effects than using DI maps with similar levels of smoothing. CONCLUSION: Artificial neural networks represent a new approach to inversion of MRE data. Summary results from NNI and DI are highly correlated and both are capable of detecting biologically relevant signals. Preliminary evidence suggests that NNI stiffness estimates may be more resistant to noise than an algebraic DI approach. Taken together, these results merit future investigation into NNIs to improve the estimation of stiffness in small regions. Magn Reson Med 80:351-360, 2018.

PMID- 29193307 TI - Approaching ultimate intrinsic specific absorption rate in radiofrequency shimming using high-permittivity materials at 7 Tesla. AB - PURPOSE: The aim of this study was to evaluate the effect of integrated high permittivity materials (HPMs) on excitation homogeneity and global specific absorption rate (SAR) for transmit arrays at 7T. METHODS: A rapid electrodynamic simulation framework was used to calculate L-curves associated with excitation of a uniform 2D profile in a dielectric sphere. We used ultimate intrinsic SAR as an absolute performance reference to compare different transmit arrays in the presence and absence of a layer of HPM. We investigated the optimal permittivity for the HPM as a function of its thickness, the sample size, and the number of array elements. RESULTS: Adding a layer of HPM can improve the performance of a 24-element array to match that of a 48-element array without HPM, whereas a 48 element array with HPM can perform as well as a 64-element array without HPM. Optimal relative permittivity values changed based on sample and coil geometry, but were always within a range obtainable with readily available materials (epsilonr = 100-200). CONCLUSION: Integration of HPMs could be a practical method to improve RF shimming performance, alternative to increasing the number of coils. The proposed simulation framework could be used to explore the design of novel transmit arrays for head imaging at ultra-high field strength. Magn Reson Med 80:391-399, 2018.

AB - BACKGROUND: Chronic kidney disease (CKD) is common in companion animals. Secondary hyperparathyroidism is an inevitable consequence of the disease and may have deleterious effect on the bone; however, the information regarding CKD associated bone abnormalities in companion animals is scarce. HYPOTHESIS/OBJECTIVES: Dogs with CKD have decreased bone quality compared to dogs without CKD. ANIMALS: Nine dogs diagnosed with naturally occurring CKD for at least 6 months and 9 age-matched controls. METHODS: Dogs with CKD were enrolled and compared to 9 age-, weight-, and sex-matched control dogs with no evidence of CKD. Samples were assessed using light microscopy, mechanical testing, and microcomputed tomography. Variables evaluated included microstructural features such as number, size, and density of Haversian canals, resorption cavities and osteocytic lacunae, bone mineral density, porosity and Young's modulus. RESULTS: Median lacunae size was significantly smaller in the CKD group compared to the control group (P = 0.001). Resorption cavity density was higher in the CKD compared to the control group (10 [8-14] vs. 7 [4-9]/mm2 , respectively, P = 0.001). Overall porosity was significantly (2.3-fold) higher in the CKD compared to the control group. There was no difference in Young's moduli between groups. CONCLUSIONS AND CLINICAL IMPORTANCE: Naturally occurring CKD affects bone quality in dogs, but these changes are relatively mild and likely not to be manifested clinically. The duration of the disease in dogs evaluated here is short compared to cats and human patients, likely accounting for the more subtle changes in dogs compared to other species. PMID- 29193310 TI - Bacterial modulators of bone remodeling in the periodontal pocket. AB - The signaling network involved in the pathogenesis of periodontal disease is not yet fully understood. This review aims to describe possible mechanisms through which the bacterial modulators may be linked directly or indirectly to the process of alveolar bone loss in periodontitis. From the late 1970s to present, new paradigm shifts have been developed regarding our understanding of pathological bone remodeling in periodontal disease. Upcoming evidence suggests that in periodontal disease the local immune response is exacerbated and involves the existence of signaling pathways that have been shown to modulate bone-cell function leading to alveolar bone loss. Those complex signaling pathways have been observed not only between bacteria but also between bacteria and the gingival surface of the host. More specifically, it has been shown that bacteria, through their secretion molecules, may interact indirectly and directly with immune-type cells of the host, resulting in the production of osteolytic agents that enhance bone resorption. Further research is required to provide a clear understanding of the role of these molecules in the pathogenesis of periodontal disease, and the availability of new technologies, such as next-generation sequencing and metagenomic analysis, may be useful tools in achieving this. PMID- 29193311 TI - Proteomics analysis of human breast milk to assess breast cancer risk. AB - Detection of breast cancer (BC) in young women is challenging because mammography, the most common tool for detecting BC, is not effective on the dense breast tissue characteristic of young women. In addition to the limited means for detecting their BC, young women face a transient increased risk of pregnancy associated BC. As a consequence, reproductively active women could benefit significantly from a tool that provides them with accurate risk assessment and early detection of BC. One potential method for detection of BC is biochemical monitoring of proteins and other molecules in bodily fluids such as serum, nipple aspirate, ductal lavage, tear, urine, saliva and breast milk. Of all these fluids, only breast milk provides access to a large volume of breast tissue, in the form of exfoliated epithelial cells, and to the local breast environment, in the form of molecules in the milk. Thus, analysis of breast milk is a non invasive method with significant potential for assessing BC risk. Here we analyzed human breast milk by mass spectrometry (MS)-based proteomics to build a biomarker signature for early detection of BC. Ten milk samples from eight women provided five paired-groups (cancer versus control) for analysis of dysregulatedproteins: two within woman comparisons (milk from a diseased breast versus a healthy breast of the same woman) and three across women comparisons (milk from a woman with cancer versus a woman without cancer). Despite a wide range in the time between milk donation and cancer diagnosis (cancer diagnosis occurred from 1 month before to 24 months after milk donation), the levels of some proteins differed significantly between cancer and control in several of the five comparison groups. These pilot data are supportive of the idea that molecular analysis of breast milk will identify proteins informative for early detection and accurate assessment of BC risk, and warrant further research. Data are available via ProteomeXchange with identifier PXD007066. PMID- 29193312 TI - Understanding Age-Induced Cortical Porosity in Women: The Accumulation and Coalescence of Eroded Cavities Upon Existing Intracortical Canals Is the Main Contributor. AB - Intracortical bone remodeling normally ensures maintenance of the cortical bone matrix and strength, but during aging, this remodeling generates excessive porosity. The mechanism behind the age-induced cortical porosity is poorly understood and addressed in the present study. This study consists of a histomorphometric analysis of sections of iliac bone specimens from 35 women (age 16-78 years). First, the study shows that the age-induced cortical porosity reflects an increased pore size rather than an increased pore density. Second, it establishes a novel histomorphometric classification of the pores, which is based on the characteristics of the remodeling sites to which each pore is associated. It takes into consideration (i) the stage of the remodeling event at the level where the pore is sectioned, (ii) whether the event corresponds with the generation of a new pore through penetrative tunneling (type 1 pores) or with remodeling of an existing pore (type 2 pores), and (iii) in the latter case, whether or not the new remodeling event leads to the coalescence of pores. Of note, the advantage of this classification is to relate porosity with its generation mechanism. Third, it demonstrates that aging and porosity are correlated with: a shift from type 1 to type 2 pores, reflecting that the remodeling of existing pores is higher; an accumulation of eroded type 2 pores, reflecting an extended resorption-reversal phase; and a coalescence of these eroded type 2 pores into enlarged coalescing type 2 cavities. Collectively, this study supports the notion, that age-related increase in cortical porosity is the result of intracortical remodeling sites upon existing pores, with an extended reversal-resorption phase (eroded type 2 pores) that may likely result in a delayed or absent initiation of the subsequent bone formation.

AB - Epilepsy, characterized by recurrent seizures and abnormal electrical activity in the brain, is one of the most prevalent brain disorders. Over two million people in the United States have been diagnosed with epilepsy and 3% of the general population will be diagnosed with it at some point in their lives. While most developmental epilepsies occur due to genetic predisposition, a class of "acquired" epilepsies results from a variety of brain insults. A leading etiological factor for epilepsy that is currently on the rise is traumatic brain injury (TBI), which accounts for up to 20% of all symptomatic epilepsies. Remarkably, the presence of an identified early insult that constitutes a risk for development of epilepsy provides a therapeutic window in which the pathological processes associated with brain injury can be manipulated to limit the subsequent development of recurrent seizure activity and epilepsy. Recent studies have revealed diverse pathologies, including enhanced excitability, activated immune signaling, cell death, and enhanced neurogenesis within a week after injury, suggesting a period of heightened adaptive and maladaptive plasticity. An integrated understanding of these processes and their cellular and molecular underpinnings could lead to novel targets to arrest epileptogenesis after trauma. This review attempts to highlight and relate the diverse early changes after trauma and their role in development of epilepsy and suggests potential strategies to limit neurological complications in the injured brain. PMID- 29193313 TI - Estimating the number of potential family members eligible for BRCA1 and BRCA2 mutation testing in a "Traceback" approach. AB - U.S. guidelines recommend BRCA1/2 mutation testing for women diagnosed with high grade ovarian cancer (HGOC) to increase recognition of carriers, but most remain unidentified and at risk. Accordingly, an approach termed "Traceback" has been proposed in which probands are retrospectively identified by testing archived pathology specimens, and family members are traced to provide genetic counseling and testing. We used population-based data to estimate the number of family members who might be contacted through such a program. We used incidence data from the Surveillance, Epidemiology, and End Results (SEER) Program to estimate the number of women diagnosed with HGOC from 2005 to 2016, and census data to estimate the number of spouses, offspring, and siblings (both sexes). Using overall survival for HGOC from SEER and all-cause mortality rates from the Centers for Diseases Control and Prevention, we estimated the number of patients, spouses, offspring, and siblings of HGOC cases living in 2017. Due to the high mortality rate of HGOC, consent from living probands may be possible in only 42% of the cases; consent to test pathology specimens would need to be sought from next of kin for the remainder. In 2017, an estimated 406,919 living next of kin (spouses, siblings, offspring) would be available for potential consent. Testing archived ovarian cancer pathology specimens may enable the identification of BRCA1/2 mutation carriers, but consent from next of kin would be required in in 58% of cases. Although Traceback offers the possibility of identifying unaffected BRCA1/2 mutation carriers, pilot feasibility studies that include assessment of methods to secure consent are needed. PMID- 29193314 TI - Effects of wobble board training on single-leg landing neuromechanics. AB - Balance training programs have been shown to reduce ankle sprain injuries in sports, but little is known about the transfer from this training modality to motor coordination and ankle joint biomechanics in sport-specific movements. This study aimed to investigate the effects of wobble board training on motor coordination and ankle mechanics during early single-leg landing from a lateral jump. Twenty-two healthy men were randomly assigned to either a control or a training group, who engaged in 4 weeks of wobble board training. Full-body kinematics, ground reaction force, and surface electromyography (EMG) from 12 lower limb muscles were recorded during landing. Ankle joint work in the sagittal, frontal, and transverse plane was calculated from 0 to 100 ms after landing. Non-negative matrix factorization (NMF) was applied on the concatenated EMG Pre- and Post-intervention. Wobble board training increased the ankle joint eccentric work 1.2 times in the frontal (P < .01) and 4.4 times in the transverse plane (P < .01) for trained participants. Wobble board training modified the modular organization of muscle recruitment in the early landing phase by separating the activation of plantar flexors and mediolateral ankle stabilizers. Furthermore, the activation of secondary muscles across motor modules was reduced after training, refocusing the activation on the main muscles involved in the mechanical main subfunctions for each module. These results suggest that wobble board training may modify motor coordination when landing from a lateral jump, focusing on the recruitment of specific muscles/muscle groups that optimize ankle joint stability during early ground contact in single-leg landing. PMID- 29193315 TI - Review shows that implementing a nationwide protocol for congenital diaphragmatic hernia was a key factor in reducing mortality and morbidity. AB - : The French Rare Disease Reference Center for congenital diaphragmatic hernia (CDH) was created in 2008, to implement a national protocol for foetuses and children with this serious condition. Neonatal mortality from CDH is 30-40%, mainly due to pulmonary hypoplasia and persistent pulmonary hypertension, and half of those who live have high respiratory, nutritional and digestive morbidity. CDH management requires long-term and specialised multidisciplinary care. It has been well established that a standardised management protocol improves the prognosis of children with CDH. CONCLUSION: Organising health care and implementing a nationwide French protocol were key factors for reducing mortality and morbidity from CDH. PMID- 29193316 TI - Posttraumatic Stress Symptom Trajectories Among Children After Disaster Exposure: A Review. AB - Natural disasters, such as hurricanes and floods, are increasing in frequency and scope. Youth exposed to disasters are at risk for developing posttraumatic stress symptoms (PTSS). However, not all youth who report initially elevated PTSS report persistent PTSS that last beyond the first three to six months postdisaster. Thus, it is crucial to understand how and why youth differ in their patterns of PTSS. This study reviewed the literature on children's postdisaster PTSS, evaluating the typical number and types of patterns for children's PTSS trajectories, as well as risk and protective factors predicting trajectory membership. This review identified eight empirical studies on youth PTSS trajectories following natural disasters; these studies included 8,306 children aged 3 to 18 years. All studies identified resilience, recovery, and chronic trajectories. Evidence for a delayed trajectory was mixed. Proportions of children falling into each trajectory varied widely across studies, but overall, resilience was the most prevalent trajectory. These findings were consistent across study factors (i.e., analytic strategy, assessment timing, and study selection criteria). Female gender, disaster exposure, negative coping, and lack of social support were significant risk factors for chronic trajectories across several studies. Future research should combine individual level participant data across studies of children's responses to disasters to better understand PTSS trajectories. PMID- 29193317 TI - Addressing the wicked problem of childhood trauma through a nursing and cooperative extension system collaboration. AB - The purpose of this clinical concept report is to describe a public health project in rural Indiana that addressed the complex social issue or "wicked problem" of childhood trauma. The project was implemented through a unique partnership between nursing faculty and Cooperative Extension Educators, community-based workers who are associated with fulfilling the mission of Land Grant Universities. The core focus of the project entailed a nurse and a Cooperative Extension Educator co-teaching trauma-informed parenting classes to rural dwelling, kinship caregivers. Kinship caregivers are often grandparents who assume the parenting role after the child has been removed from the birth parents' care. The trauma-informed curriculum was developed by experts in child trauma and is available through the National Child Traumatic Stress Network. The unique partnership provided insight into the different missions of the two organizations, different values and workflow metrics, and different schedules, which at times proved to be barriers to implementation.

AB - BACKGROUND: Children with deprivation amblyopia due to childhood cataract have been excluded from much of the emerging research into amblyopia treatment. An investigation was conducted to determine whether contrast-balanced binocular treatment - a strategy currently being explored for children with anisometropic and strabismic amblyopia - may be effective in children with deprivation amblyopia. METHODS: An unmasked, case-series design intended to assess proof of principle was employed. Eighteen children with deprivation amblyopia due to childhood cataracts (early bilateral n = 7, early unilateral n = 7, developmental n = 4), as well as 10 children with anisometropic (n = 8) or mixed anisometropic and strabismic amblyopia (n = 2) were prescribed one hour a day of treatment over a six-week period. Supervised treatment was available. Visual acuity, contrast sensitivity, global motion perception and interocular suppression were measured pre- and post-treatment. RESULTS: Visual acuity improvements occurred in the anisometropic/strabismic group (0.15 +/- 0.05 logMAR, p = 0.014), but contrast sensitivity did not change. As a group, children with deprivation amblyopia had a smaller but statistically significant improvement in weaker eye visual acuity (0.09 +/- 0.03 logMAR, p = 0.004), as well a significant improvement in weaker eye contrast sensitivity (p = 0.004). Subgroup analysis suggested that the children with early bilateral deprivation had the largest improvements, while children with early unilateral cataract did not improve. Interestingly, binocular contrast sensitivity also improved in children with early bilateral deprivation. Global motion perception improved for both subgroups with early visual deprivation, as well as children with anisometropic or mixed anisometropic/strabismic amblyopia. Interocular suppression improved for all subgroups except children with early unilateral deprivation. CONCLUSION: These data suggest that supervised contrast-balanced binocular treatment should be further investigated as a treatment option for children with deprivation amblyopia. However, for children with more severe deprivation amblyopia due to early unilateral cataracts, supplementary or alternative options should also be explored.

PMID- 29193322 TI - Vision screening at two years does not reduce the prevalence of reduced vision at four and a half years of age. AB - BACKGROUND: There is currently insufficient evidence to recommend vision screening for children < 36 months of age. This study assessed the effect of comprehensive vision screening, as well as the sensitivity of age-appropriate vision tests, at two years of age on habitual visual acuity at 4.5 years of age. METHODS: Children born at risk of neonatal hypoglycaemia (n = 477) underwent vision assessment at 54 +/- 2 months of age including measurement of monocular and binocular habitual visual acuity, assessment of binocularity and stereopsis. Of these children, 355 (74.4 per cent) had also received vision screening at two years of age (mean age = 24+/- 1 months), while 122 were not screened. RESULTS: Eighty (16.8 per cent) children were classified as having reduced vision at 4.5 years of age, but the prevalence of reduced vision did not differ between children who had previously been screened at two years of age and those who had not (15.5 per cent versus 20.5 per cent, p = 0.153). However, children with reduced vision at 4.5 years of age were more likely to have had visual abnormalities requiring referral detected at two years of age (p = 0.02). Visual acuity and mean spherical equivalent autorefraction measurements were also worse (higher values) in two-year-old children who were later classified with reduced habitual visual acuity (p = 0.031 and p = 0.001, respectively). Nevertheless, unaided binocular visual acuity, non-cycloplegic refractive error, and stereopsis at two years all showed poor sensitivity and specificity for predicting visual outcomes at 4.5 years of age. CONCLUSION: Our findings do not support the adoption of early vision screening in children as current vision tests suitable for use with two-year-old children have poor sensitivity for predicting mild moderate habitual vision impairment at 4.5 years of age.

AB - Signal amplification by reversible exchange (SABRE) is a hyperpolarisation technique that catalytically transfers nuclear polarisation from parahydrogen, the singlet nuclear isomer of H2 , to a substrate in solution. The SABRE exchange reaction is carried out in a polarisation transfer field (PTF) of tens of gauss before transfer to a stronger magnetic field for nuclear magnetic resonance (NMR) detection. In the simplest implementation, polarisation transfer is achieved by shaking the sample in the stray field of a superconducting NMR magnet. Although convenient, this method suffers from limited reproducibility and cannot be used with NMR spectrometers that do not have appreciable stray fields, such as benchtop instruments. Here, we use a simple hand-held permanent magnet array to provide the necessary PTF during sample shaking. We find that the use of this array provides a 25% increase in SABRE enhancement over the stray field approach, while also providing improved reproducibility. Arrays with a range of PTFs were tested, and the PTF-dependent SABRE enhancements were found to be in excellent agreement with comparable experiments carried out using an automated flow system where an electromagnet is used to generate the PTF. We anticipate that this approach will improve the efficiency and reproducibility of SABRE experiments carried out using manual shaking and will be particularly useful for benchtop NMR, where a suitable stray field is not readily accessible. The ability to construct arrays with a range of PTFs will also enable the rapid optimisation of SABRE enhancement as function of PTF for new substrate and catalyst systems.

PMID- 29193326 TI - Tibiotarsus bone characteristics and tibial dyschondroplasia incidence of broilers fed diets supplemented with leucine and valine. AB - Two experiments were conducted to study the effect of standardized ileal digestible (SID) leucine and valine levels on tibiotarsus bone characteristics and the incidence of tibial dyschondroplasia of broilers from day 1 to 21 (Experiment I) and day 21 to 42 post-hatch (Experiment II). Each experimental phase was evaluated independently. In both experiments, a total of 1,500 one-day old Cobb 500 male broiler chickens were distributed in a completely randomized design 5 * 5 factorial arrangement for a total of 25 treatments. The SID leucine and valine levels were ranged from 10.0 to 19.6 g/kg, and 6.0 to 12.0 g/kg from day 1 to 21 post-hatch, respectively, while day 21 to 42 post-hatch ranged from 10.0 to 18.0 g leucine/kg, and 5.2 to 11.2 g valine/kg. Serum calcium and phosphorus, bone concentrations of calcium, phosphorus and ash, diameter and Seedor index of the tibiotarsus were not affected (p > .05) by the treatments at 21 or 42 days of age. There was an interaction (p <=.06) between the SID levels of leucine and valine on tibiotarsus breaking strength at 21 days, but not at 42 days of age (p > .05). Tibiotarsus breaking strength was maximized in broilers from day 1 to 21 with the dietary levels of leucine and valine at 14.2 and 9.0 g/kg respectively. Dietary leucine levels reduced linearly (p < .05) the hypertrophic zone of tibiotarsus cartilage at 21 days of age. Therefore, leucine and valine supplementation interact positively on bone strength of broilers from day 1 to 21 post-hatch. Leucine can be a useful amino acid for reducing the hypertrophic cartilage zone in broilers from day 1 to 21, but not from day 21 to 42 post-hatch. PMID- 29193327 TI - Effects of Toceranib Phosphate on the Hypothalamic-Pituitary-Thyroid Axis in Tumor-Bearing Dogs. AB - BACKGROUND: Thyroid dysfunction is associated with the use of tyrosine kinase inhibitors (TKI) in people. HYPOTHESIS/OBJECTIVES: To determine whether dysfunction in the hypothalamic-pituitary-thyroid axis occurs in dogs receiving the TKI, toceranib phosphate. ANIMALS: Forty-three client-owned dogs with cancer. METHODS: Prospective, observational study. Concentrations of total thyroxine (TT4), free thyroxine (FT4), total triiodothyronine (TT3), and thyroid stimulating hormone (TSH) were evaluated on day 0, 30, and 90. Dogs also were evaluated for the presence of thyroglobulin autoantibodies. RESULTS: The proportion of dogs with low TT4, low FT4, low TT3, high TSH, or primary hypothyroidism (increased TSH and decreased TT4, FT4 or both) did not change over 90 days. Hormone concentrations remained within laboratory reference intervals, but FT4 (P = 0.0032) and TSH (P < 0.0001) changed over time. Mean FT4 was 1.22 ng/dL (95% confidence interval [CI], 1.10-1.34) on day 0 and 1.00 ng/dL (95% CI, 0.86-1.16) on day 90. Mean TSH was 0.17 ng/mL (95% CI, 0.13-0.23) on day 0 and 0.34 ng/mL (95% CI, 0.24-0.48) on day 90. Furthermore, TT4/TT3 ratio also changed over time (P = 0.0086). Mean TT4/TT3 ratio was 2.57 (95% CI, 2.26-2.88) on day 0 and 2.02 on day 90 (95% CI, 1.61-2.44). Thyroglobulin autoantibodies were not detected in any dog. CONCLUSIONS AND CLINICAL IMPORTANCE: Toceranib phosphate can disrupt the hypothalamic-pituitary-thyroid axis in dogs. Periodic evaluation of TT4, FT4, TT3, and TSH should be carried out in dogs receiving long-term treatment with this medication. PMID- 29193328 TI - Transport of valine across the small intestinal epithelium in pigs fed different valine levels and Bacillus subtilis. AB - Mutants of Bacillus subtilis overproducing valine (B. subtilis VAL) could be an approach to supply pigs dietary valine (Val). In the study, 18 gilts were fed: (i) negative diet with a standardized ileal digestible (SID) Val:Lys of 0.63:1 (Neg); (ii) Neg added B. subtilis VAL (1.28 * 1011 cfu/kg as-fed) or; (iii) Neg added L-Val to a Val:Lys of 0.69:1. Using the Ussing chamber method, the study aimed to investigate whether (i) the diets affect intestinal transport of additions of 0, 5, 10 or 20 mmol Val/L from the mucosal to the serosal side and (ii) the B. subtilis VAL contributes to a net transport of Val produced in situ. The results showed that the Isc (DeltaIscVal ) and release of Val to the serosal side solution (Srel ; MUmol cm-2 min-1 ) increased with Val addition (linear and quadratic, p < .0001) but was similar for 5, 10 or 20 mmol Val/L and not affected by diet. No net transport of in situ produced Val by B. subtilis VAL was detected. In conclusion, feeding a Val-deficient diet with or without B. subtilis VAL or a Val sufficient diet did not affect the Val transport across intestinal epithelia. No in situ Val production by B. subtilis VAL was observed in the Ussing chambers.

PMID- 29193330 TI - A DNA-Threaded ZIF-8 Membrane with High Proton Conductivity and Low Methanol Permeability. AB - Natural biomolecules have potential as proton-conducting materials, in which the hydrogen-bond networks can facilitate proton transportation. Herein, a biomolecule/metal-organic framework (MOF) approach to develop hybrid proton conductive membranes is reported. Single-strand DNA molecules are introduced into DNA@ZIF-8 membranes through a solid-confined conversion process. The DNA-threaded ZIF-8 membrane exhibits high proton conductivity of 3.40 * 10-4 S cm-1 at 25 degrees C and the highest one ever reported of 0.17 S cm-1 at 75 degrees C, under 97% relatively humidity, attributed to the formed hydrogen-bond networks between the DNA molecules and the water molecules inside the cavities of the ZIF 8, but very low methanol permeability of 1.25 * 10-8 cm2 s-1 due to the small pore entrance of the DNA@ZIF-8 membranes. The selectivity of the DNA@ZIF-8 membrane is thus significantly higher than that of developed proton-exchange membranes for fuel cells. After assembling the DNA@ZIF-8 hybrid membrane into direct methanol fuel cells, it exhibits a power density of 9.87 mW cm-2 . This is the first MOF-based proton-conductivity membrane used for direct methanol fuel cells, providing bright promise for such hybrid membranes in this application. PMID- 29193331 TI - Host modulation therapy with anti-inflammatory agents. AB - Host modulation therapy refers to a treatment concept in which drug therapies are used as an adjunct to conventional periodontal treatment to ameliorate destructive aspects of the host inflammatory response. This strategy is not new in the treatment of periodontitis. Previously, nonsteroidal anti-inflammatory drugs have been investigated in this regard, with evidence of reductions in alveolar bone resorption when these drugs are used for prolonged periods of time. However, the risk of significant unwanted effects precludes the use of both nonselective nonsteroidal anti-inflammatory drugs and the selective cyclooxygenase-2 inhibitors as adjunctive treatments for periodontitis. Currently, the only available adjunctive host response modulator that is licensed for the treatment of periodontitis is subantimicrobial dose doxycycline, which functions as an inhibitor of matrix metalloproteinases. Although clinical benefits have been shown in carefully conducted randomized controlled trials, the efficacy of subantimicrobial dose doxycycline in routine clinical practice has yet to be determined. Anti-cytokine therapies have been developed for use in the treatment of rheumatoid arthritis, the pathogenesis of which bears many similarities to that of periodontitis; however, the significant risk of unwanted effects (as well as cost and lack of human trials in the treatment of periodontal diseases) precludes the use of any of the currently available anti-cytokine therapies in the treatment of periodontitis. The identification of pro-resolving lipid mediators as well as small molecule biologicals that influence inflammatory responses offers the best potential, at the present time, for the development of novel host response modulators in periodontal therapy, but much research remains to be done to confirm safety and efficacy. PMID- 29193332 TI - Humidity-Responsive ON/OFF Switching of Gas Inclusion by Using Cooperative Opening/Closing of Heterogeneous Crystalline Cavities in a Peptide NiII Macrocycle. AB - Humidity-responsive ON/OFF switching of CO2 inclusion, associated with cooperative structural changes of heterogeneous cavities in crystalline peptide NiII macrocycles, 1?NO3 , is demonstrated. The structural transformation between an "open form" and a "closed form" was caused by reversible water uptake into one of the cavities. The adsorption behavior of CO2 was studied with and without water vapor, combined with gas-composition analysis by using gas chromatography. The studies revealed that the open form of 1?NO3 adsorbs CO2 gas up to 34 g mol-1 , whereas the closed form adsorbs only a negligible amount of CO2 gas. Also, structural studies (X-ray and IR spectroscopies) and investigation of water content dependence of CO2 adsorption revealed that the switching of gas inclusion occurred abruptly over a narrow range of water-vapor pressure and was caused by the cooperative opening of vacant space to give the open form due to the structural transformation by water uptake. PMID- 29193333 TI - Repeated MitraClip procedure in patients with recurrent MR after a successful first procedure: Limitations and outcome. AB - OBJECTIVES: The present study aimed to evaluate the outcome and potential limitations of a repeated MitraClip procedure (ReClip). BACKGROUND: The MitraClip procedure has emerged as a treatment option in high surgical risk patients suffering from severe mitral regurgitation (MR). However, despite successful initial repair a significant number of patients develops severe recurrent MR. METHODS: Patients undergoing a ReClip procedure in our institution were retrospectively identified. Baseline data and the procedural outcome were assessed to identify potential limitations of such procedures. RESULTS: Fifteen out of 234 patients undergoing a mitral-valve repair with the MitraClip device (Abbott Vascular) underwent a ReClip due to recurrent MR. In 11 patients, a MR reduction of at least one degree without causing mitral valve stenosis (trans mitral mean gradient >=5 mmHg) was achieved by performing a ReClip. After 1 year, two patients developed severe recurrent MR again. Pulmonary artery pressures significantly decreased after the procedure in individuals with successful repair (MR reduction of at least one degree and mitral valve mean gradient <5 mmHg). CONCLUSION: A ReClip procedure may be feasible in patients with recurrent MR but the risk benefit ratio should be carefully balanced against other treatment options. PMID- 29193334 TI - Comparison of peri-implant and periodontal marginal soft tissues in health and disease. AB - The integrity of the peri-implant soft-tissue seal is crucial for maintaining peri-implant tissue health. Whilst the transmucosal component of the restored implant shares some common features with teeth, namely the presence of a junctional epithelium and a connective tissue component, there are some important differences. A key difference is the nature of the relationship of the connective tissue with the implant surface, whereby there is 'adaptation' of collagen fibers in a parallel orientation in relation to the implant, but insertion of fiber attachment perpendicularly into cementum in the case of teeth. This, combined with reduced cellularity and vascularity in the peri-implant connective tissue, may make implants more susceptible to disease initiation and progression. Furthermore, the presence of a subgingival connection between the implant and the abutment/restoration poses some specific challenges, and maintaining the integrity of this connection is important in preserving peri-implant tissue health. Implant design features, such as the nature of the connection between the implant and the abutment, as well as the surface characteristics of the abutment and implants, may influence the maintenance of the integrity of soft tissue around implants. Iatrogenic factors, such as incorrect seating of the abutment and/or the restoration, and the presence of residual subgingival cement, will lead to loss of soft-tissue integrity and hence predispose to peri-implant disease.

AB - Inspired by the experimentally synthesized Na12 @[(UO2 )(O2 )1.5 ]208- ("Na12 @U20 ") cluster, we have explored computationally the substitution of the Na cations by many other metals. 6 other M12 @U20 systems are found to be stable (M=K+ , Rb+ , Cs+ , Ag+ , Mg2+ , Fe2+ ). For 3 of these (Mg2+ , Ag+ and Na+ ), the cluster can support a group 16 dianion at its center, forming a new type of Matryoshka ("Russian Doll") actinide nanocluster E@M12 @U20 (E=S2- , Se2- , Te2- , and Po2- ). These systems have 3-shell, onion-like geometries with nearly perfect Ih symmetry. Seeking to create clusters with very high spin ground states, we have replaced M by Mn2+ and U20 by Np20 and Pu20 , generating clusters with maximum possible S values of 80/2 and 100/2 respectively. Only in the presence of a central S2- , however, are these electronic configurations the most stable; the novel Matryoshka Pu nanocluster S@Mn12 @Pu20 is predicted to have the highest ground state spin yet reported for a molecular cluster. PMID- 29193337 TI - The novel echo-guided ProGlide technique during percutaneous transfemoral transcatheter aortic valve implantation. AB - OBJECTIVES: The aim of this study was to assess clinical benefit of the Echo guided ProGlide technique in patients undergoing percutaneous transfemoral transcatheter aortic valve implantation (TF-TAVI). BACKGROUND: The efficacy of the Echo-guided ProGlide technique during percutaneous TF-TAVI was not previously clarified. METHODS: A total of 121 consecutive patients who underwent percutaneous TF-TAVI at our institution between February 2014 and July 2017 were enrolled in this study. According to the introduction of this novel technique in March 2016, patients were divided into two groups (echo-guided group who underwent TAVI from March 2016 to July 2017, n = 63; not echo-guided group who underwent TAVI from February 2014 to February 2016, n = 58). The incidence of major vascular complications, defined per the Valve Academic Research Consortium 2 criteria, and ProGlide complications including acute femoral artery stenosis or occlusion and bleeding requiring any intervention. RESULTS: The incidence of major vascular complication and ProGlide complication were significantly lower in the echo-guided group than in not echo-guided group (1.6% vs 17.2%, P < 0.002; 1.6% vs 15.5%, P = 0.003; respectively). Use of the Echo-guided ProGlide technique was independently associated with prevention of ProGlide complications (odds ratio, 0.11; 95% confidential interval, 0.01-0.76; P = 0.03). CONCLUSIONS: This novel Echo-guided ProGlide technique was associated with a lower rate of major vascular complications, particularly ProGlide complications during percutaneous TF-TAVI. PMID- 29193338 TI - The association amongst visual, hearing, and dual sensory loss with depression and anxiety over 6 years: The Tromso Study. AB - OBJECTIVE: To examine the longitudinal association of dual and single (vision and hearing) sensory loss on symptoms of depression and anxiety in older adults. METHODS: Two thousand eight hundred ninety adults aged 60 years or over who participated in the longitudinal population-based Tromso Study, Norway, were included. The impact of objective vision loss, self-report hearing loss, or dual sensory loss on symptoms of depression and anxiety, as assessed by the Hopkins Symptom Checklist 10, was examined at baseline and 6-year follow-up using linear mixed models. RESULTS: Hearing loss had a cross-sectional relationship with increased depression (b = 0.1750, SE = 0.07, P = .02) and anxiety symptoms (b = 0.1765, SE = 0.08, P = .03); however, these relationships were not significant at the 6-year follow-up. Both vision loss only and dual sensory loss predicted increased depression scores at follow-up (b = 0.0220, SE = 0.01, P = .03; and b = 0.0413, SE = 0.02, P = .01, respectively). Adjustment for social isolation did not attenuate the main depression results. CONCLUSION: Dual sensory loss resulted in increased depression symptomatology over time and posed an additional long term risk to depression severity beyond having a single sensory loss only. Only hearing loss is associated with anxiety symptoms. Older adults with vision, hearing, and dual sensory loss have different mental health profiles. Therefore, management and intervention should be tailored to the type of sensory loss. PMID- 29193339 TI - A rapid T1 mapping method for assessment of murine kidney viability using dynamic manganese-enhanced magnetic resonance imaging. AB - PURPOSE: Dynamic manganese-enhanced MRI (MEMRI) allows assessment of tissue viability by tracing manganese uptake. We aimed to develop a rapid T1 mapping method for dynamic MEMRI to facilitate assessments of murine kidney viability. METHODS: A multi-slice saturation recovery fast spin echo (MSRFSE) was developed, validated, and subsequently applied in dynamic MEMRI at 16.4T on ischemic mouse kidneys after 4 weeks of unilateral renal artery stenosis (RAS). Baseline T1 values and post-contrast R1 (1/T1 ) changes were measured in cortex (CO), outer (OSOM), inner (ISOM) strips of outer medulla, and inner medulla (IM). RESULTS: Validation studies showed strong agreement between MSRFSE and an established saturation recovery Look-Locker method. Baseline T1 (s) increased in the stenotic kidney CO (2.10 [1.95-2.56] vs. 1.88 [1.81-2.00], P = 0.0317) and OSOM (2.17 [2.05-2.33] vs. 1.96 [1.87-2.00], P = 0.0075) but remained unchanged in ISOM and IM. This method allowed a temporal resolution of 1.43 min in dynamic MEMRI. Mn2+ uptake and retention decreased in stenotic kidneys, particularly in the OSOM (DeltaR1 : 0.48 [0.38-0.56] vs. 0.64 [0.61-0.69] s-1 , P < 0.0001). CONCLUSION: Dynamic MEMRI by MSRFSE detected decreased cellular viability and discerned the regional responses to RAS. This technique may provide a valuable tool for noninvasive evaluation of renal viability. Magn Reson Med 80:190-199, 2018. (c) 2017 International Society for Magnetic Resonance in Medicine. PMID- 29193340 TI - Template-based field map prediction for rapid whole brain B0 shimming. AB - PURPOSE: In typical MRI protocols, time is spent acquiring a field map to calculate the shim settings for best image quality. We propose a fast template based field map prediction method that yields near-optimal shims without measuring the field. METHODS: The template-based prediction method uses prior knowledge of the B0 distribution in the human brain, based on a large database of field maps acquired from different subjects, together with subject-specific structural information from a quick localizer scan. The shimming performance of using the template-based prediction is evaluated in comparison to a range of potential fast shimming methods. RESULTS: Static B0 shimming based on predicted field maps performed almost as well as shimming based on individually measured field maps. In experimental evaluations at 7 T, the proposed approach yielded a residual field standard deviation in the brain of on average 59 Hz, compared with 50 Hz using measured field maps and 176 Hz using no subject-specific shim. CONCLUSIONS: This work demonstrates that shimming based on predicted field maps is feasible. The field map prediction accuracy could potentially be further improved by generating the template from a subset of subjects, based on parameters such as head rotation and body mass index.

AB - Apoptotic signaling pathways are altered in numerous pathologies such as cancer. In this scenario, caspase-9/PP2Acalpha interaction constitutes a key target with pharmacological interest to re-establish apoptosis in tumor cells. Very recently, a short peptide (C9h) known to disrupt caspase-9/PP2Acalpha interaction with subsequent apoptosis induction was described. Here, we prepared two sets of mesoporous silica nanoparticles loaded with safranin O (S2) or with C9h peptide (S4) and functionalized with epsilon-polylysine as capping unit. Aqueous suspensions of both nanoparticles showed negligible cargo release whereas in the presence of pronase, a marked delivery of safranin O or C9h was observed. Confocal microscopy studies carried out with HeLa cells indicated that both materials were internalized and were able to release their entrapped cargos. Besides, a marked decrease in HeLa cell viability (ca. 50 %) was observed when treated with C9h-loaded S4 nanoparticles. Moreover, S4 provides peptide protection from degradation additionally allowing for a dose reduction to observe an apoptotic effect when compared with C9h alone or in combination with a cell penetrating peptide (i.e., Mut3DPT-C9h). Flow cytometry studies, by means of Annexin V-FITC staining, showed the activation of apoptotic pathways in HeLa as a consequence of S4 internalization, release of C9h peptide and disruption of caspase-9/PP2Acalpha interaction. PMID- 29193346 TI - Biomimetic Platelet-Camouflaged Nanorobots for Binding and Isolation of Biological Threats. AB - One emerging and exciting topic in robotics research is the design of micro /nanoscale robots for biomedical operations. Unlike industrial robots that are developed primarily to automate routine and dangerous tasks, biomedical nanorobots are designed for complex, physiologically relevant environments, and tasks that involve unanticipated biological events. Here, a biologically interfaced nanorobot is reported, made of magnetic helical nanomotors cloaked with the plasma membrane of human platelets. The resulting biomimetic nanorobots possess a biological membrane coating consisting of diverse functional proteins associated with human platelets. Compared to uncoated nanomotors which experience severe biofouling effects and hence hindered propulsion in whole blood, the platelet-membrane-cloaked nanomotors disguise as human platelets and display efficient propulsion in blood over long time periods. The biointerfaced nanorobots display platelet-mimicking properties, including adhesion and binding to toxins and platelet-adhering pathogens, such as Shiga toxin and Staphylococcus aureus bacteria. The locomotion capacity and platelet-mimicking biological function of the biomimetic nanomotors offer efficient binding and isolation of these biological threats. The dynamic biointerfacing platform enabled by platelet membrane cloaked nanorobots thus holds considerable promise for diverse biomedical and biodefense applications.

AB - Tunability of the open-shell character, charge asymmetry, and third-order nonlinear optical (NLO) properties of covalently linked (hetero)phenalenyl dimers are investigated by using the density functional theory method. By changing the molecular species X and substitution position (i, j) for the linker part, a variety of intermonomer distances R and relative alignments between the phenalenyl dimers can be realized from the geometry optimizations, resulting in a wide-range tuning of diradical character y and charge asymmetry. It is found that the static second hyperpolarizabilities along the stacking direction, gammayyyy , are one-order enhanced for phenalenyl dimer systems exhibiting intermediate y, a feature that is in good agreement with the "y-gamma correlation". By replacing the central carbon atoms of the phenalenyl rings with a boron or a nitrogen, we have also designed covalently linked heterophenalenyl dimers. The introduction of such a charge asymmetry to the open-shell systems, which leads to closed-shell ionic ground states, is found to further enhance the gammayyyy values of the systems having longer intermonomer distance R with intermediate ionic character, that is, charge asymmetry. The present results demonstrate a promising potential of covalently linked NLO dimers with intermediate open-shell/ionic characters as a new building block of highly efficient NLO systems.

Semen analysis, anthropometric, physical activity assessments, total antioxidant capacity, malondialdehyde, inflammatory factors, and reproductive hormones were measured at the baseline and at the end of the study. At the end of study, statistically significant differences were seen in the total sperm count, sperm concentration, and motility in the intervention group to the control group. In treatment group, the total sperm count, sperm concentration, and motility levels were also statistically increased at the end of study compared to the baseline values. Curcumin nanomicelle supplementation also resulted in a statistically significant improvement in plasma levels of total antioxidant capacity, malondialdehyde, C-reactive protein, and tumor necrosis factor a in comparison to the placebo. Medical therapy of asthenoteratospermia with curcumin nanomicelle supplement could improve quality of semen parameters. However, further investigation is suggested in this regard.

AB - A systematic review and network-meta analysis (NMA) were performed to test significance of the galactagogue effect of fenugreek administrated to lactating women versus other comparators (i.e., placebo/control/other galactagogues). A pairwise comparison for the treatment effect was carried out to generate the forest plot for the NMA. League tables were generated using treatment effect, weighted mean difference (WMD; 95% confidence interval, CI) for all pairwise comparisons, where WMD > 0 favors the column-defining treatment. Five studies were identified with 122 participants receiving treatment with fenugreek. The NMA results of 4 studies indicated that consumption of fenugreek significantly increased amount of the produced breast milk [11.11, CI 95% 6.77, 15.46] versus placebo. The pairwise comparison revealed that fenugreek was effective as a galactagogue compared to placebo, control, and reference groups WMD 17.79 [CI 11.71, 23.88]. However, the effect of fenugreek was substantially inferior to Coleus amboinicus Lour and palm date. The NMA using pairwise comparison demonstrated the effect of C. amboinicus and palm date in the stimulation of the breast milk production was comparable and superior to all comparators. PMID- 29193353 TI - Gingival crevicular fluid and its immune mediators in the proteomic era. AB - The discovery of biomarkers for periodontal disease requires an in-depth understanding of the molecular basis of the initiation and progression of the disease. The gingival crevicular fluid is a biological medium suitable for identifying and measuring such biomarkers because it can be easily and noninvasively sampled from the immediate vicinity of the affected tissues. An ever-expanding pool of gingival crevicular fluid proteins associated with periodontal health or disease has been catalogued over the years, particularly with the recent implementation of proteomic technologies. 'Proteomics' refers to the large-scale study of entire arrays of proteins expressed by a genome and present in a cell, tissue, biological fluid or organism. Hence, such technologies provide a broad qualitative and quantitative insight of the proteins present in gingival crevicular fluid. Pertinent studies have amassed on the information gathered to date on protein signatures in periodontal health and disease, and have confirmed the nature of the immunological host response. This review discusses the application of proteomic technologies in characterizing the molecular networks present in gingival crevicular fluid, their potential for discovery of biomarkers that are meaningful for clinical practice, and the associated technical challenges. PMID- 29193354 TI - Decursin attenuates the amyloid-beta-induced inflammatory response in PC12 cells via MAPK and nuclear factor-kappaB pathway. AB - Decursin, the major bioactive component of Angelica gigas Nakai, exhibited neuroprotective properties. Our previous studies showed that decursin conferred neuroprotective effects in PC12 cells induced by Amyloid-beta (Abeta)25-35 via antiapoptosis and antioxidant. In this study, the antiinflammatory effects of decursin against PC12 cells injury stimulated by Abeta25-35 were assessed. Our results demonstrated that decursin suppressed the expression of cyclooxygenase-2 protein and prostaglandin E2 content which was stimulated by Abeta25-35 in PC12 cells. Meanwhile, the nuclear translocation of nuclear factor-kappaB in Abeta25 35 -treated PC12 cells was also inhibited by decursin. In addition, decursin suppressed phosphorylation of the two upstream pathway kinases, p38 and c-Jun N terminal kinase. Overall, our findings indicate that decursin exerts protective effects against neuroinflammation stimulated by Abeta25-35 in PC12 cells by abolishing cyclooxygenase-2 protein expression through inactivation of nuclear factor-kappaB via the upstream kinases including p38 and c-Jun N-terminal kinase. This work provides a new insight into the pharmacological mode of decursin and should facilitate its therapeutic application in treatment of inflammatory disorders. PMID- 29193355 TI - Development of the gingival sulcus at the time of tooth eruption and the influence of genetic factors. AB - Tooth eruption is characterized by a concert of mechanisms that result in the emergence of teeth in the oral cavity. Genetic variants seem to regulate this process and the formation of a gingival sulcus around the teeth. Interindividual variability in the response to microbial triggers in the sulcus plays an important role in the onset and progression of periodontal diseases. Host genetic variants can influence this variability, affecting the response of the host to the subgingival biofilm. Genetic factors affecting tooth eruption could potentially influence susceptibility to periodontal diseases and, specifically, susceptibility to localized aggressive periodontitis. This review aims to discuss the evidence available for the role of host genetic variants in tooth eruption and to and to give some directions for prospective research in this topic. PMID- 29193356 TI - Sofosbuvir plus daclatasvir with or without ribavirin is safe and effective for post-transplant hepatitis C recurrence and severe fibrosis and cirrhosis: A prospective study. AB - BACKGROUND: In 2012, an Italian Named Patient Program began for hepatitis C virus (HCV)-infected liver transplant (LT) recipients with advanced fibrosis, before approval of direct antiviral agents (DAA), to benefit severely ill patients. The aim of this "real-life" study was to assess treatment efficacy and safety with an extended course of daclatasvir (DCV) plus sofosbuvir (SOF) with or without ribavirin (RBV). METHODS: All HCV LT recipients with severe fibrosis in 15 Italian transplant centers were treated with DCV+SOF+/-RBV for 24 weeks; sustained virological response was assessed at 12 weeks post-treatment (SVR12). RESULTS: Eighty-seven patients were enrolled (75.9% males, mean age 58.4 +/- 7.2 years, 83.9% genotype 1, 81.6% cirrhosis); 52 (59.8%) received RBV. Overall, 79 obtained SVR12 (90.8%): 100% in F3 and 88.7% in cirrhotics (91.5% in Child-Pugh A, 83.3% in Child-Pugh B and C). According to the treatment group, SVR was 80% in DCV + SOF group and 98.1% in SOF + DCV + RBV. Two virological relapses occurred during follow-up in cirrhotic patients who received DCV + SOF. Four cirrhotic patients in DCV + SOF group and 1 in DCV + SOF + RBV group died on treatment. CONCLUSION: An extended course of SOF plus DCV for 24 weeks, with or without RBV, is effective and well tolerated for the treatment of post-LT HCV recurrence with severe fibrosis. PMID- 29193357 TI - What phytotherapy needs: Evidence-based guidelines for better clinical practice. AB - In recent decades, the pharmacological properties of numerous medicinal plants and opportunities in phytotherapy have been explored through research projects, reviews, and monographs. These studies confirm that medicinal plants offer new approaches to tackling diseases. However, improvement of phytotherapy in clinical practice relies on a number of critical factors. In particular, the studies are very heterogeneous, and results and their interpretation by healthcare workers vary greatly, so preventing consistency in clinical practice. There is therefore a lost opportunity to improve phytotherapy practice, because the work being done and the related systematic reviews cannot act as a body of data on which to base clear clinical recommendations. Approaches such as the Grading of Recommendations Assessment, Development and Evaluation or the Scottish Intercollegiate Guidelines Network methodology could easily help standardise the use of phytotherapy in clinical practice. In this context, evidence-based phytotherapy guidelines could offer new healthcare approaches to the treatment of diseases. PMID- 29193359 TI - Consensus Statement on the classification of tremors. from the task force on tremor of the International Parkinson and Movement Disorder Society. AB - BACKGROUND: Consensus criteria for classifying tremor disorders were published by the International Parkinson and Movement Disorder Society in 1998. Subsequent advances with regard to essential tremor, tremor associated with dystonia, and other monosymptomatic and indeterminate tremors make a significant revision necessary. OBJECTIVES: Convene an international panel of experienced investigators to review the definition and classification of tremor. METHODS: Computerized MEDLINE searches in January 2013 and 2015 were conducted using a combination of text words and MeSH terms: "tremor", "tremor disorders", "essential tremor", "dystonic tremor", and "classification" limited to human studies. Agreement was obtained using consensus development methodology during four in-person meetings, two teleconferences, and numerous manuscript reviews. RESULTS: Tremor is defined as an involuntary, rhythmic, oscillatory movement of a body part and is classified along two axes: Axis 1-clinical characteristics, including historical features (age at onset, family history, and temporal evolution), tremor characteristics (body distribution, activation condition), associated signs (systemic, neurological), and laboratory tests (electrophysiology, imaging); and Axis 2-etiology (acquired, genetic, or idiopathic). Tremor syndromes, consisting of either isolated tremor or tremor combined with other clinical features, are defined within Axis 1. This classification scheme retains the currently accepted tremor syndromes, including essential tremor, and provides a framework for defining new syndromes. CONCLUSIONS: This approach should be particularly useful in elucidating isolated tremor syndromes and syndromes consisting of tremor and other signs of uncertain significance. Consistently defined Axis 1 syndromes are needed to facilitate the elucidation of specific etiologies in Axis 2. (c) 2017 International Parkinson and Movement Disorder Society. PMID- 29193358 TI - Cardiovascular magnetic resonance elastography: A review. AB - Cardiovascular diseases are the leading cause of death worldwide. These cardiovascular diseases are associated with mechanical changes in the myocardium and aorta. It is known that stiffness is altered in many diseases, including the spectrum of ischemia, diastolic dysfunction, hypertension and hypertrophic cardiomyopathy. In addition, the stiffness of the aortic wall is altered in multiple diseases, including hypertension, coronary artery disease and aortic aneurysm formation. For example, in diastolic dysfunction in which the ejection fraction is preserved, stiffness can potentially be an important biomarker. Similarly, in aortic aneurysms, stiffness can provide valuable information with regard to rupture potential. A number of studies have addressed invasive and non invasive approaches to test and measure the mechanical properties of the myocardium and aorta. One of the non-invasive approaches is magnetic resonance elastography (MRE). MRE is a phase-contrast magnetic resonance imaging technique that measures tissue stiffness non-invasively. This review article highlights the technical details and application of MRE in the quantification of myocardial and aortic stiffness in different disease states. PMID- 29193361 TI - Automatic analysis of corneal nerves imaged using in vivo confocal microscopy. AB - Interest has grown over the past decade in using in vivo confocal microscopy to analyse the morphology of corneal nerves and their changes over time. Advances in computational modelling techniques have been applied to automate the estimation of sub-basal nerve structure. These objective methods have the potential to quantify nerve density (and length), tortuosity, variations in nerve thickness, as well as temporal changes in nerve fibres such as migration patterns. Different approaches to automated nerve analysis, methods proposed and how they were validated in previous literature are reviewed. Improved understanding of these approaches and their limitations will help improve the diagnostic leverage of emerging developments for monitoring the onset and progression of a broad class of systemic diseases, including diabetes. PMID- 29193360 TI - Patterns of late-life depressive symptoms and subsequent declines in cognitive domains. AB - BACKGROUND: Depression frequently co-occurs with cognitive decline, but the nature of this association is unclear. We examined relations of late-life depressive symptom patterns to subsequent domain-specific cognitive changes. METHODS: Depressive symptoms were measured at up to 3 timepoints among 11,675 Nurses' Health Study participants prior to cognitive testing. Depressive symptom patterns were categorized as non-depressed, variable or persistent, based on published severity cutpoints. Outcomes were global, verbal, and executive function-attention composite scores. RESULTS: Participants with persistent depressive symptoms had worse executive function-attention decline compared with non-depressed participants (multivariable-adjusted mean difference = -0.03 units/year, 95% CI: -0.05, -0.01; p = 0.003); this difference was comparable with 8 years of aging. However, being in the persistent versus non-depressed group was not significantly related to verbal (p = 0.71) or global score (p = 0.09) decline. By contrast, compared with the non-depressed group, those with variable depressive symptoms had worse verbal memory decline (multivariable-adjusted mean difference = -0.01 units/year, 95% CI: -0.02, -0.002; p = 0.03); this group showed no differences for global or executive function-attention decline. CONCLUSIONS: A variable pattern of depressive symptom severity related to subsequent decline in verbal memory, while a persistent pattern related to decline in executive function-attention. Findings could signal differences in underlying neuropathologic processes among persons with differing depression patterns and late-life cognitive decline. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 29193362 TI - Donor-specific anti-HLA antibodies are not associated with nonanastomotic biliary strictures but both are independent risk factors for graft loss after liver transplantation. AB - Donor-specific alloantibodies (DSA) have been associated with rejection and shorter graft survival after orthotopic liver transplantation (OLT). We examined the role of DSA in nonanastomotic biliary strictures (NAS) after OLT. Patients receiving first OLT who developed NAS (n = 68) and a control group without NAS (n = 83), with pre-OLT and 12 months post-OLT serum samples, were included. DSA were specified using the Luminex single antigen test. Risk factors for NAS and graft survival were analyzed. The presence of preformed DSA was not significantly different between patients with NAS and controls (P = .89). After 12 months, 26.5% of NAS patients and 16.9% of controls had generated de novo DSA (P = .15). Neither de novo class I DSA nor de novo class II DSA were associated with NAS. De novo DSA generally developed after the diagnosis of NAS. Time-dependent regression analysis identified both NAS (aHR 8.05, CI 3.28 - 19.77, P < .01) and de novo class II DSA (aHR 2.84, CI 1.38 - 5.82, P < .01) as independent risk factors for graft loss. Preformed or de novo DSA were not associated with the development of NAS. However, NAS as well as de novo class II DSA were independent risk factors for graft loss after OLT. PMID- 29193363 TI - Anti-MRSA activity of oxysporone and xylitol from the endophytic fungus Pestalotia sp. growing on the Sundarbans mangrove plant Heritiera fomes. AB - Heritiera fomes Buch.-Ham., a mangrove plant from the Sundarbans, has adapted to a unique habitat, muddy saline water, anaerobic soil, brackish tidal activities, and high microbial competition. Endophytic fungal association protects this plant from adverse environmental conditions. This plant is used in Bangladeshi folk medicine, but it has not been extensively studied phytochemically, and there is hardly any report on investigation on endophytic fungi growing on this plant. In this study, endophytic fungi were isolated from the surface sterilized cladodes and leaves of H. fomes. The antimicrobial activities were evaluated against two Gram-positive and two Gram-negative bacteria and the fungal strain, Candida albicans. Extracts of Pestalotia sp. showed activities against all test bacterial strains, except that the ethyl acetate extract was inactive against Escherichia coli. The structures of the purified compounds, oxysporone and xylitol, were elucidated by spectroscopic means. The anti-MRSA potential of the isolated compounds were determined against various MRSA strains, that is, ATCC 25923, SA 1199B, RN4220, XU212, EMRSA-15, and EMRSA-16, with minimum inhibitory concentration values ranging from 32 to 128 MUg/ml. This paper, for the first time, reports on the anti-MRSA property of oxysporone and xylitol, isolation of the endophyte Pestalotia sp. from H. fomes, and isolation of xylitol from a Pestalotia sp. PMID- 29193364 TI - The influence and mechanism of ligustilide, senkyunolide I, and senkyunolide A on echinacoside transport through MDCK-MDR1 cells as blood-brain barrier in vitro model. AB - Efficient transcytosis across the blood-brain-barrier is an important strategy for accessing drug targets within the central nervous system. Ligusticum chuanxiong Hort. was used as a messenger drug to increase the distribution of drugs in brain tissue in Traditional Chinese Medicine. The present study investigates the transport of echinacoside (ECH) through MDCK-MDR1 cell and the effects of ligustilide (LIG), senkyunolide A (SENA) and senkyunolide I (SENI) in chuanxiong on its transport. The results indicated that the absorption of ECH was relatively poor in MDCK-MDR1cells, and was concentration dependent and not saturable. The P-glycoprotein inhibitor verapamil could significantly increase the transport of ECH. It indicated that the transport mechanism might be passive diffusion as the dominating process with the active transportation mediated mechanism involved. The increased apparent permeability of ECH in A -> B direction by ethylenediaminetetraacetic acid-Na2 suggested that ECH was absorbed via the paracellular route. The transport of ECH in A -> B direction significantly increased when co-administrated with increasing concentrations of LIG, SENI and SENA. Western blot analysis and a decrease in transepithelial electrical resistance during the permeation experiment indicated that LIG, SENI and SENA had enhanced the transport of ECH in the BBB models attribute to down regulate the expressions of claudin-5 and zonula occludens-1 expression. PMID- 29193365 TI - Making the leap to medical education: a qualitative study of medical educators' experiences. AB - CONTEXT: Medical educators often have prior and primary experience in other academic and clinical disciplines. Individuals seeking successful careers in the education of medical students and doctors must, at some point in their development, make a conscious transition into a new identity as a medical educator. This is a necessary move if individuals are to commit to acquiring and maintaining specialist expertise in medical education. Some achieve this transition successfully, whereas others struggle and may even lose interest and abandon the endeavour. We explored senior educators' experiences of achieving the transition into medical education and their views on what helps and what hinders the process. METHODS: In 2015 we conducted three focus groups with 15 senior medical educators. All focus group discussions were audiorecorded and transcribed verbatim. We applied transition theory to guide our deductive analysis, using Schlossberg's Four S (4S) framework to code and report participants' self reported perceptions of those factors relating to Self, Situation, Support and Strategy that had assisted them to make a successful transition to a fully acknowledged medical educator identity. Through inductive analysis, we then identified 17 explanatory sub-themes common to all three focus groups. RESULTS: Background and circumstances, individual motivation, a sense of control, organisational support, and effective networking and information-seeking behaviour were factors identified as contributing to successful transition into, and maintenance of, a strong self-identity as a medical educator. CONCLUSIONS: The experiences of established medical educators and, in particular, an exploration of the factors that have facilitated their transition to an acknowledged self-identity as a medical educator could assist in supporting new educators to cope with the changes involved in developing as a medical educator. PMID- 29193366 TI - Self-Assembled alpha-Cyanostilbenes for Advanced Functional Materials. AB - In the specific context of condensed media, the significant and increasing recent interest in the alpha-cyanostilbene (CS) motif [?Ar?CH?C(CN)?Ar?] is relevant. These compounds have shown remarkable optical features in addition to interesting electrical properties, and hence they are recognized as very suitable and versatile options for the development of functional materials. This progress report is focused on current and future use of CS structures and molecular assemblies with the aim of exploring and developing for the next generations of functional materials. A critical selection of illustrative materials that contain the CS motif, including relevant subfamilies such as the dicyanodistyrylbenzene and 2,3,3-triphenylacrylonitrile shows how, driven by the self-assembly of CS blocks, a variety of properties, effects, and possibilities for practical applications can be offered to the scientific community, through different rational routes for the elaboration of advanced materials. A survey is provided on the research efforts directed toward promoting the self-assembly of the solid state (polycrystalline solids, thin films, and single crystals), liquid crystals, nanostructures, and gels with multistimuli responsiveness, and applications for sensors, organic light-emitting diodes, organic field effect transistors, organic lasers, solar cells, or bioimaging purposes.

AB - Microalgae represent a rich source that satisfies the growing need for novel ingredients of nutriceuticals, pharmaceuticals, and food supplements. Haematococcus pluvialis and Dunaliella salina microalgae are isolated from the Egyptian hydro-flora and are reported for their potent antioxidant activities. The cytotoxic activity of different fractions of both microalgae was investigated on 4 cell lines HePG2, MCF7, HCT116, and A549. The carotenoid rich fraction of H. pluvialis showed potent cytotoxic activity against colon cancer cell line and moderate activity against both liver and breast cancer cell lines. On the other hand, the carotenoid rich fraction of D. salina showed mild cytotoxic activity on breast and liver cancer cell lines. The carotenoid rich fraction of H. pluvialis was analysed using LC-DAD/ESI-MS and the major carotenoids were identified either free as well as bounded to fatty acids. PMID- 29193368 TI - Curcumin, an antibiotic resistance breaker against a multiresistant clinical isolate of Mycobacterium abscessus. AB - Curcumin, a phenolic compound extracted from Curcuma longa, exerts multiple pharmacological effects, including an antimicrobial action. Mycobacterium abscessus, an environmental, nontuberculous, rapidly growing mycobacterium, is an emerging human pathogen causing serious lung infections and one of the most difficult to treat, due to its multidrug resistance and biofilm-forming ability. We wanted to evaluate the antimicrobial and antivirulence activity of curcumin and its ability to synergize with antibiotics against a clinical M. abscessus strain (29904), isolated from the bronchoaspirate of a 66-year-old woman admitted to hospital for suspected tuberculosis. Curcumin [minimum inhibitory concentrations (MIC) = 128 mg/L] was synergic (fractional inhibitory concentration index <=0.5) with amikacin, clarithromycin, ciprofloxacin, and linezolid, to which strain 29904 showed resistance/intermediate susceptibility. Curcumin at 1/8 * MIC significantly reduced motility, whereas at 4 * MIC, it completely inhibited 4- and 8-day mature biofilms. Synergistic combinations of curcumin and amikacin induced a general reduction in microbial aggregates and substantial loss in cell viability. Disruption of 4- and 8-day biofilms was the main effect detected when curcumin was the predominant compound. The present findings support previous evidence that curcumin is a potential antibiotic resistance breaker. Curcumin, either alone or combined with antibiotics, could provide a novel strategy to combat antibiotic resistance and virulence of M. abscessus.

AB - Filled tetrahedral semiconductors are a rich family of compounds with tunable electronic structure, making them ideal for applications in thermoelectrics, photovoltaics, and battery anodes. Furthermore, these materials crystallize in a plethora of related structures that are very close in energy, giving rise to polytypism through the manipulation of synthetic parameters. This Minireview highlights recent advances in the solution-phase synthesis and nanostructuring of these materials. These methods enable the synthesis of metastable phases and polytypes that were previously unobtainable. Additionally, samples synthesized in solution phase have enhanced thermoelectric performance due to their decreased grain size.

AB - We demonstrate, based on experimental and theoretical evidence, that the isolated [2(CH3 CN)2 ]2+ complex prepared in CH3 CN and containing a mixed-valent {Cu2II,I S} core evolves towards a new [2(CH3 CN)3 ]2+ species upon solvation in CH3 CN. Unlike its type III structural analogue [2(H2 O)(OTf)]+ active toward N2 O reduction, this new type I compound is inactive. This outcome opens new perspectives for a rational for N2 O activation using bio-inspired Cu/S complexes, especially on the role of the valence localization/delocalization and the Cu-Cu bond on the reactivity.

AB - Urinary tract infections, genital tract infections and sexually transmitted infections are the most prevalent infectious diseases, and the establishment of locally optimized guidelines is critical to provide appropriate treatment. The Urological Association of Asia has planned to develop the Asian guidelines for all urological fields, and the present urinary tract infections, genital tract infections and sexually transmitted infections guideline was the second project of the Urological Association of Asia guideline development, which was carried out by the Asian Association of Urinary Tract Infection and Sexually Transmitted Infection. The members have meticulously reviewed relevant references, retrieved via the PubMed and MEDLINE databases, published between 2009 through 2015. The information identified through the literature review of other resources was supplemented by the author. Levels of evidence and grades of recommendation for each management were made according to the relevant strategy. If the judgment was made on the basis of insufficient or inadequate evidence, the grade of recommendation was determined on the basis of committee discussions and resultant consensus statements. Here, we present a short English version of the original guideline, and overview its key clinical issues. PMID- 29193371 TI - Differential interaction of PRMT1 with RGG-boxes of the FET family proteins EWS and TAF15. AB - The FET sub-family (FUS/TLS, EWS, TAF15) of RNA-binding proteins have remarkably similar overall structure but diverse biological and pathological roles. The molecular basis for FET protein specialization is largely unknown. Gly-Arg-Rich regions (RGG-boxes) within FET proteins are targets for methylation by Protein Arginine-Methyl-Transferase-1 (PRMT1) and substrate capture is thought to involve electrostatic attraction between positively charged polyRGG substrates and negatively charged surface channels of PRMT1. Unlike FUS and EWS, a high proportion of TAF15 RGG-boxes are embedded within neutrally charged YGGDR(S/G)G repeats, suggesting that they might not bind well to PRMT1. This notion runs contrary however to a report that YGGDR(S/G)G repeats are methylated by PRMT1. Using peptide-based polyRGG substrates and a novel 2-hybrid binding assay, we find that the Asp residue in YGGDR(S/G)G repeats confers poor binding to PRMT1. Our results therefore indicate that YGGDR(S/G)G repeats may contribute to TAF15 specialization by enabling differential interactions with PRMT1 and reduced overall levels of TAF15 methylation compared with other FET proteins. By analogy with molecular recognition of other disordered polyvalent ligands by globular protein partners, we also propose a dynamic polyelectrostatic model for substrate capture by PRMT1.

AB - The organometallic tris-cyclopentadienide actinide(III) (AnCp3 ) complexes were first reported about 50 years ago. However, up until now, only the NpCp3 solid state structure has been studied. Here we report on the solid state structures of UCp3 and PuCp3 which are isostructural to the Np analogue. The structural models are supported by theoretical calculations and compared to their lanthanide analogues. The observed trends in changes of bond lengths might be indicator for an increased covalency in the bonding in the tris-cyclopentadienide actinide(III) complexes (AnCp3 ) compared to their lanthanide homologues. PMID- 29193374 TI - Tunable Emission from Fluorescent Organic Nanoparticles in Water: Insight into the Nature of Self-Assembly and Photoswitching. AB - Excitation-dependent tuning of the emission behavior of fluorescent organic nanoparticles (FONs) with two simple luminescent pyrenyl-pyridyl conjugates as model systems is demonstrated. In the case of the compound with a flexible bis picolyl moiety, the simultaneous presence of multiple ground-state species with distinct absorption and emission characteristics can be observed. The relative ratios of these species can easily be modulated, and it is possible to selectively stimulate any one of them individually by choosing an appropriate excitation channel. Moreover, at high concentration, a drastic change in the nature of the self-assembly is observed, which shifts from donor-acceptor-type self-assembly to exciplex-type self-agglomeration. On the contrary, the compound containing a rigid terpyridine unit has only a single ground state and shows no such tunable emission. However, it can exhibit multiple emission bands in water, whereby the positions of their emission maxima depend on the extent of aggregation-induced planarization of the probe molecules. Overall, this work demonstrates multimodal modulation of FON emission and a gives insight into how molecular order can translate into complete switching of nanoparticle self assembly and photophysics. PMID- 29193375 TI - National Comparative Audit of Blood Transfusion: report on the 2014 audit of patient information and consent. AB - OBJECTIVES: The aim of this study was to assess current practices around obtaining consent for blood transfusion and provision of patient information in hospitals across the UK and identify areas for improvement. BACKGROUND: Recommendations from the Advisory Committee on the Safety of Blood, Tissues and Organs (SaBTO) (2011) state that valid consent should be obtained for blood transfusion and documented in clinical records. A standardised source of information should be available to patients. Practices in relation to this have historically been inconsistent. METHODS: The consent process was studied in hospitals across the UK over a 3-month period in 2014 by means of an audit of case notes and simultaneous surveys of patients and staff. RESULTS: In total, 2784 transfusion episodes were reviewed across 164 hospital sites. 85% of sites had a policy on consent for transfusion. Consent was documented in 43% of case notes. 68% of patients recalled being given information on benefits of transfusion, 38% on risks and 8% on alternatives and 28% reported receiving an information leaflet. In total, 85% of staff stated they had explained the reason for transfusion, but only 65% had documented this. 41% of staff had received training specifically on transfusion consent in the last 2 years. CONCLUSIONS: There is a need to improve clinical practice in obtaining valid consent for transfusion in line with existing national guidelines and local Trust policies, with emphasis on documentation within clinical records. Provision of patient information is an area particularly highlighted for action, and transfusion training for clinicians should be strengthened. PMID- 29193376 TI - Evaluation of left ventricular reverse remodeling in patients with severe aortic regurgitation undergoing aortic valve replacement: Comparison between diameters and volumes. AB - BACKGROUND: In patients with severe aortic regurgitation (AR), the left ventricular ejection fraction (LVEF) and left ventricle (LV) size are crucial for determining clinical prognosis and timing of valve intervention. In clinical practice, LV internal diameters obtained at end-diastole are used to assess the degree of LV dilatation. Whether quantification of LV volumes would provide more robust information as compared to LV linear dimensions is unknown. METHODS: We retrospectively analyzed preoperative and postoperative transthoracic echocardiograms of patients who underwent aortic valve replacement (AVR) for severe AR. Indexed linear LV end-diastolic and end-systolic diameters along with indexed LV end-diastolic and end-systolic volumes were obtained as per current guidelines. Post-AVR LV reverse remodeling, defined as >=10% reduction in measures of LV volumes (Teichholz and Simpson's methods), was determined. Positive and negative agreement was calculated between the volume- and diameter based LV reverse remodeling. RESULTS: Sixty-two consecutive patients were included. Nine patients (17%) without LV reverse remodeling based on Teichholz were reclassified as having LV reverse remodeling based on Simpson (positive agreement 0.846 [95% CI 0.772, 0.921], negative agreement 0.200 [95% CI -0.350, 0.435]). Left ventricle (LV) reverse remodeling assessed by the Teichholz method was underestimated by a mean of 31 mL/m2 (beta = -0.65 [95% CI -1.06 to -0.24], P = .003) compared to Simpson method. CONCLUSION: Compared to the volume-based method, diameter-based LV measurement incorrectly identified LV reverse remodeling post-AVR in 17% of patients with severe AR. Left ventricle (LV) volume may be a better measure to assess LV remodeling post-AVR than LV diameter-based measurements.

AB - Onychomycosis is a common fungal infection in dermatology clinics. The commonly used diagnostic method, potassium hydroxide (KOH) direct microscopy, does not have a high-positive detection rate. Therefore, a new diagnostic method is needed to confirm onychomycosis. The objective of this research was to use fluorescent brightener 85 (FB 85), a new fluorescent reagent for fungi detection, and to evaluate this new method based on the diagnostic positive rate, accuracy and efficiency in suspected onychomycosis compared with the KOH method. Subungual debris was collected from clinically suspected onychomycosis cases and divided into two parts. The parts were examined by FB 85 and 10% KOH solution, respectively. In total, 108 patients with suspected onychomycosis were recruited. The positive rates of FB 85 and KOH were 88.9% and 55.6%, respectively. The patients showed significant statistical differences (P < .001). Compared with the KOH method, the FB 85 fluorescent method was an accurate and efficient method with a higher positive rate. This method could increase the diagnostic accuracy and efficiency of onychomycosis detection. PMID- 29193378 TI - Acid-Triggered O-O Bond Heterolysis of a Nonheme FeIII (OOH) Species for the Stereospecific Hydroxylation of Strong C-H Bonds. AB - A novel hydroperoxoiron(III) species [FeIII (OOH)(MeCN)(PyNMe3 )]2+ (3) has been generated by reaction of its ferrous precursor [FeII (CF3 SO3 )2 (PyNMe3 )] (1) with hydrogen peroxide at low temperatures. This species has been characterized by several spectroscopic techniques and cryospray mass spectrometry. Similar to most of the previously described low-spin hydroperoxoiron(III) compounds, 3 behaves as a sluggish oxidant and it is not kinetically competent for breaking weak C-H bonds. However, triflic acid addition to 3 causes its transformation into a much more reactive compound towards organic substrates that is capable of oxidizing unactivated C-H bonds with high stereospecificity. Stopped-flow kinetic analyses and theoretical studies provide a rationale for the observed chemistry, a triflic-acid-assisted heterolytic cleavage of the O-O bond to form a putative strongly oxidizing oxoiron(V) species. This mechanism is reminiscent to that observed in heme systems, where protonation of the hydroperoxo intermediate leads to the formation of the high-valent [(Porph. )FeIV (O)] (Compound I).

AB - BACKGROUND/OBJECTIVES: Pediatricians manage skin conditions such as atopic dermatitis (AD) but report that their dermatologic training is inadequate. Online modules may enhance medical education when sufficient didactic or clinical teaching experiences are lacking. We assessed whether an online module about AD improved pediatric residents' knowledge and changed their clinical management of AD. METHODS: Target and control cohorts of pediatric residents from two institutions were recruited. Target subjects took a 30-question test about AD early in their residency, reviewed the online module, and repeated the test 6 months and 1 year later. The control subjects, who had 1 year of clinical experience but had not reviewed the online module, also took the test. The mean percentage of correct answers was calculated and compared using two-sided, two sample independent t tests and repeated-measures analysis of variance. For a subset of participants, clinical documentation from AD encounters was reviewed and 13 practice behaviors were compared using the Fisher exact test. RESULTS: Twenty-five subjects in the target cohort and 29 subjects in the control cohort completed the study. The target cohort improved from 18.0 +/- 3.2 to 23.4 +/- 3.4 correctly answered questions over 1 year (P < .001). This final value was greater than that of the control cohort (20.7 +/- 4.5; P = .01). Meaningful differences in practice behaviors were not seen. CONCLUSION: Pediatric residents who reviewed an online module about AD demonstrated statistically significant improvement in disease-specific knowledge over time and had statistically significantly higher scores than controls. Online dermatology education may effectively supplement traditional clinical teaching. PMID- 29193380 TI - Optimization and validation of accelerated golden-angle radial sparse MRI reconstruction with self-calibrating GRAPPA operator gridding. AB - PURPOSE: Golden-angle radial sparse parallel (GRASP) MRI reconstruction requires gridding and regridding to transform data between radial and Cartesian k-space. These operations are repeatedly performed in each iteration, which makes the reconstruction computationally demanding. This work aimed to accelerate GRASP reconstruction using self-calibrating GRAPPA operator gridding (GROG) and to validate its performance in clinical imaging. METHODS: GROG is an alternative gridding approach based on parallel imaging, in which k-space data acquired on a non-Cartesian grid are shifted onto a Cartesian k-space grid using information from multicoil arrays. For iterative non-Cartesian image reconstruction, GROG is performed only once as a preprocessing step. Therefore, the subsequent iterative reconstruction can be performed directly in Cartesian space, which significantly reduces computational burden. Here, a framework combining GROG with GRASP (GROG GRASP) is first optimized and then compared with standard GRASP reconstruction in 22 prostate patients. RESULTS: GROG-GRASP achieved approximately 4.2-fold reduction in reconstruction time compared with GRASP (~333 min versus ~78 min) while maintaining image quality (structural similarity index ~ 0.97 and root mean square error ~ 0.007). Visual image quality assessment by two experienced radiologists did not show significant differences between the two reconstruction schemes. With a graphics processing unit implementation, image reconstruction time can be further reduced to approximately 14 min. CONCLUSION: The GRASP reconstruction can be substantially accelerated using GROG. This framework is promising toward broader clinical application of GRASP and other iterative non Cartesian reconstruction methods. Magn Reson Med 80:286-293, 2018.

PMID- 29193381 TI - Experiences of older people following an acute exacerbation of chronic obstructive pulmonary disease: A phenomenological study. AB - AIMS AND OBJECTIVES: To explore the experience of patients affected by chronic obstructive pulmonary disease following hospitalisation due to an acute exacerbation event. BACKGROUND: Chronic obstructive pulmonary disease is a progressively debilitating disease, often with very burdensome symptoms such as acute and chronic breathlessness and fatigue. Acute exacerbation often creates a life-threatening event. Exacerbation can also have substantial psychological effects including anxiety and depression although this aspect is less well researched-especially amongst people with chronic obstructive pulmonary disease recovering from an acute event and facing a return home. DESIGN: A descriptive phenomenological study. METHODS: In-depth interviews were conducted with 12 chronic obstructive pulmonary disease patients recently recovering from an acute exacerbation of their chronic obstructive pulmonary disease. Data were analysed using Colaizzi's phenomenological framework. RESULTS: Four themes were identified from the data: a sense of loss and frustration, hopelessness, uncertainty about the future and fear of becoming a burden. Participants expressed quite negative views including a loss of hope, uncertainty about their future care and the burden they may become on their families. They appeared stressed and anxious as a result of the acute event they had experienced. CONCLUSIONS: This study shows that an acute episode of illness can generate a sense of hopelessness and uncertainty about their future care in people with chronic obstructive pulmonary disease. This occurs as they recover physically and think about the future, often in quite negative terms. RELEVANCE TO CLINICAL PRACTICE: For healthcare professionals, it is important to take into account the potential feelings of loss, hopelessness and uncertainty that people can experience following an acute exacerbation of their chronic obstructive pulmonary disease and ensure that psychological care is available as physical recovery takes place. Such care to include good discharge planning, giving patients time to express concerns and referral to counselling services if appropriate. PMID- 29193383 TI - Blood transfusion is a critical determinant of resource utilization and total hospital cost in liver transplantation. AB - OBJECTIVE: The aim of this study is to identify factors associated with increased resource use and total hospital cost (THC) after liver transplantation (LT). METHODS: A study of LT patients undergoing surgery between January 2008 and December 2013 was performed. Main end points were LOS, intensive care unit length of stay (ICU LOS), days on the ventilator, THCs, service area costs. RESULTS: A total of 191 patients undergoing LT were included in the analysis. Creatinine and blood transfusion were significantly associated with prolonged LOS, ICU LOS, and days on the ventilator. Multivariable analysis of predictors of THC demonstrated creatinine as a strong pre-operative factor. Creatinine was also a significant predictor of OR, ICU, pharmacy, in-patient (floor), diagnostics, and ancillary services cost. After controlling for intra-operative factors such as operative time and blood transfusions, we found that transfusions were the strongest independent predictors of total cost. Patients receiving <5 units of PRBCs had a median LOS of 7 days. ICU LOS doubled and ICU total cost increased by 50% if patients required more than five transfusions of PRBCs. CONCLUSIONS: Elevated serum creatinine and blood transfusions are the most critical determinants of increased resource utilization and hospital expenditure in LT. PMID- 29193382 TI - Prediction of no-reflow and major adverse cardiovascular events with a new scoring system in STEMI patients. AB - BACKGROUND: No-reflow is associated with a poor prognosis in STEMI patients. There are many factors and mechanisms that contribute to the development of no reflow, including age, reperfusion time, a high thrombus burden, Killip class, long stent use, ejection fraction <=40, and a high Syntax score. In this study, we aimed to evaluate the parameters associated with no-reflow prediction by creating a new scoring system. METHODS: The study included 515 consecutive STEMI patients who underwent PCI; 632 STEMI patients who had undergone PCI in another center were included in the external validation of the scoring system. The correlations between 1-year major adverse cardiac events and low/high risk score were assessed. RESULTS: In this study, seven independent variables were used to build a risk score for predicting no-reflow. The predictors of no-reflow are age, EF <=40, SS >=22, stent length >=20, thrombus grade >=4, Killip class >=3, and pain-balloon time >=4 h. In the derivation group, the optimal threshold score for predicting no-reflow was >10, with a 75% sensitivity and 77.7% specificity (Area under the curve (AUC) = 0.809, 95%CI: 0.772-0.842, P < 0.001). In the validation group, AUC was 0.793 (95%CI: 0.760-0.824, P < 0.001). CONCLUSION: This new score, which can be calculated in STEMI patients before PCI and used to predict no reflow in STEMI patients, may help physicians to estimate the development of no reflow in the pre-PCI period. PMID- 29193384 TI - Concurrent isotope-assisted metabolic flux analysis and transcriptome profiling reveal responses of poplar cells to altered nitrogen and carbon supply. AB - Reduced nitrogen is indispensable to plants. However, its limited availability in soil combined with the energetic and environmental impacts of nitrogen fertilizers motivates research into molecular mechanisms toward improving plant nitrogen use efficiency (NUE). We performed a systems-level investigation of this problem by employing multiple 'omics methodologies on cell suspensions of hybrid poplar (Populus tremula * Populus alba). Acclimation and growth of the cell suspensions in four nutrient regimes ranging from abundant to deficient supplies of carbon and nitrogen revealed that cell growth under low-nitrogen levels was associated with substantially higher NUE. To investigate the underlying metabolic and molecular mechanisms, we concurrently performed steady-state 13 C metabolic flux analysis with multiple isotope labels and transcriptomic profiling with cDNA microarrays. The 13 C flux analysis revealed that the absolute flux through the oxidative pentose phosphate pathway (oxPPP) was substantially lower (~threefold) under low-nitrogen conditions. Additionally, the flux partitioning ratio between the tricarboxylic acid cycle and anaplerotic pathways varied from 84%:16% under abundant carbon and nitrogen to 55%:45% under deficient carbon and nitrogen. Gene expression data, together with the flux results, suggested a plastidic localization of the oxPPP as well as transcriptional regulation of certain metabolic branchpoints, including those between glycolysis and the oxPPP. The transcriptome data also indicated that NUE-improving mechanisms may involve a redirection of excess carbon to aromatic metabolic pathways and extensive downregulation of potentially redundant genes (in these heterotrophic cells) that encode photosynthetic and light-harvesting proteins, suggesting the recruitment of these proteins as nitrogen sinks in nitrogen-abundant conditions.

AB - A new organocatalytic strategy for the synthesis of enantioenriched aza-Baylis Hillman type products via a frustrated vinylogous reaction is presented. This process proceeds under mild conditions with good yields, completed Z/E selectivity and excellent enantioselectivities. Moreover, easy derivatizations of the final products led to important building blocks of organic synthesis such as 1,3-aminoalcohols and Lewis base catalysts. PMID- 29193386 TI - On the Structure and Reaction Mechanism of Human Acireductone Dioxygenase. AB - Acireductone dioxygenase (ARD) is an intriguing enzyme from the methionine salvage pathway that is capable of catalysing two different oxidation reactions with the same substrate depending on the type of the metal ion in the active site. To date, the structural information regarding the ARD-acireductone complex is limited and possible reaction mechanisms are still under debate. The results of joint experimental and computational studies undertaken to advance knowledge about ARD are reported. The crystal structure of an ARD from Homo sapiens was determined with selenomethionine. EPR spectroscopy suggested that binding acireductone triggers one protein residue to dissociate from Fe2+ , which allows NO (and presumably O2 ) to bind directly to the metal. Mossbauer spectroscopic data (interpreted with the aid of DFT calculations) was consistent with bidentate binding of acireductone to Fe2+ and concomitant dissociation of His88 from the metal. Major features of Fe vibrational spectra obtained for the native enzyme and upon addition of acireductone were reproduced by QM/MM calculations for the proposed models. A computational (QM/MM) study of the reaction mechanisms suggests that Fe2+ promotes O-O bond homolysis, which elicits cleavage of the C1 C2 bond of the substrate. Higher M3+ /M2+ redox potentials of other divalent metals do not support this pathway, and instead the reaction proceeds similarly to the key reaction step in the quercetin 2,3-dioxygenase mechanism. PMID- 29193387 TI - The nuclear hormone receptor E75A regulates vitellogenin gene (Al-Vg) expression in the mirid bug Apolygus lucorum. AB - Apolygus lucorum is the predominant pest of Bacillus thuringiensis (Bt) cotton in China. 20-hydroxyecdysone (20E) plays a key role in the reproduction of this insect. To better understand the mechanism underlying 20E-regulated reproduction, the nuclear hormone receptor E75 isoform-A of Ap. lucorum (Al-E75A) was cloned and its expression analysed. A 2241-bp sequence of Al-E75A cDNA encoded an open reading frame of a polypeptide with a predicted molecular mass of 69.04 kDa. Al E75A mRNA was detected in female adult stages of Ap. lucorum with peak expression in 7-day-old animals. Al-E75A was also expressed in several tissues, particularly in the fat body and ovary. A 3.2 kb Al-E75A mRNA was detected in all tissues by Northern blot. The fecundity and longevity were significantly decreased in female adults treated with Al-E75A small interfering RNA. The rates of egg incubation rates were considerably lower in the RNA interference-treated animals compared to the untreated controls. In order to investigate the molecular mechanism underlying the effects described above, vitellogenin (Al-Vg) was selected for further investigation. The expression pattern of Al-Vg was similar to that of Al E75A and was up-regulated by 20E. After knockdown of Al-E75A, the expression profile of Al-Vg and the protein levels were down-regulated. These findings suggest that Al-E75A plays a crucial role in the regulation of Al-Vg expression in Ap. lucorum. PMID- 29193388 TI - The associations of illness perception with metabolic control (HbA1c) among type 2 diabetes mellitus patients in a district hospital. AB - OBJECTIVES: Despite the availability of a wide selection of anti-diabetic treatments, many type 2 DM (T2DM) patients still do not have controlled glucose levels. In addition to pharmacological intervention, patients' own implicit beliefs about their illness should be targeted for health intervention. Thus, we conducted a quantitative study to evaluate the associations between illness perception (IP) domains and metabolic control (HbA1c) of T2DM patients in Selama Hospital and to identify patients' perceptions of the causal T2DM factors. METHOD: A cross-sectional study was conducted in the outpatient department of Selama Hospital from October to December 2015. A total of 200 T2DM patients were recruited using systematic random sampling. A self-administered validated questionnaire consisting of three sections was used, and the data were analysed using SPSS version 18. The associations between eight IP domains and HbA1c were evaluated via multiple linear regression. P values <0.05 were considered significant. KEY FINDINGS: The analysis included data from 200 respondents with a mean age of 57.7 years (SE = 9.8). The majority were women (64.5%) and Malays (86%) with a primary school education (43.5%) and a family history of diabetes (53.5%). The median duration of illness was 5 years (IQR = 7), and the median HbA1c level was 8.15% (IQR = 3.1). The mean score for the eight IP domains was 33.7 (SE = 8.43) out of a total score of 80. Using multiple linear regression, HbA1c was found to be significantly associated with IP domains of identity symptoms at 0.221 (95% CI 0.083-0.358). Moreover, 79.4% of patients ranked diet and eating behaviour as the main factor for T2DM. CONCLUSION: The IP domain of identity symptoms was significantly correlated with T2DM metabolic control. By understanding patients' IP, healthcare providers can focus on behavioural approaches to managing T2DM patients. Steps must be taken to educate patients about the importance of diet control in managing T2DM. PMID- 29193389 TI - Antimicrobial activity of copaiba oil (Copaifera ssp.) on oral pathogens: Systematic review. AB - Copaifera ssp. produces an oil-resin that presents antiinflammatory, antitumor, antiseptic, germicidal, antifungal, and antibacterial activity. This systematic review aimed to analyze the antimicrobial action of Copaiba oil against oral pathogens, when compared to that of control substances. A search on Medline/PubMed, LILACS, SciELO, EMBASE, and SCOPUS databases were performed up to March 2017. To be included, the studies needed to perform any antimicrobial activity essay, using copaiba oil and a control substance. The antimicrobial effect of each substance, in each study, was extracted. Eleven studies were included, and several copaiba species were used. All studies showed that copaiba oil, regardless of its species, presented a bactericidal and/or bacteriostatic effect in in vitro analyzes. Only one study showed that the antimicrobial effect of the Copaifera officinalis was similar to the one found in chlorhexidine. A higher risk of bias was detected in most of the included studies. The studies demonstrated that the antimicrobial activity of copaiba oil, in most cases, is lower than chlorhexidine, which is considered the gold standard. However, there is great potential against oral bacteria. Further high quality studies are warranted in order to assess the efficacy of copaiba oil on oral pathogens. PMID- 29193390 TI - Lonicera japonica Thunb. Induces caspase-dependent apoptosis through death receptors and suppression of AKT in U937 human leukemic cells. AB - Decoctions obtained from the dried flowers of Lonicera japonica Thunb. (Indongcho) have been utilized in folk remedies against inflammatory diseases. Recently, many agents that have used for inflammatory diseases are showing anticancer effects. Here, we have isolated polyphenols extracted from lyophilized Lonicera japonica Thunb (PELJ) and investigated the anticancer effects of PELJ on U937 cells. Here, we demonstrated that PELJ induced apoptosis by upregulation of DR4 and Fas, and further it is augmented by suppression of XIAP. In addition, The PELJ-induced apoptosis is at least in part by blocking PI3K/Akt pathway. These findings suggest that PELJ may provide evidence of anticancer activities on U937 cells. Further study for detailed mechanism and the effects on animal models is warranted to determine whether PELJ provide more conclusive evidence that PELJ which may provide a beneficial effect for treating cancer. PMID- 29193392 TI - Ancient chromosomal rearrangement associated with local adaptation of a postglacially colonized population of Atlantic Cod in the northwest Atlantic. AB - Intraspecific diversity is central to the management and conservation of exploited species, yet knowledge of how this diversity is distributed and maintained in the genome of many marine species is lacking. Recent advances in genomic analyses allow for genome-wide surveys of intraspecific diversity and offer new opportunities for exploring genomic patterns of divergence. Here, we analysed genome-wide polymorphisms to measure genetic differentiation between an offshore migratory and a nonmigratory population and to define conservation units of Atlantic Cod (Gadus morhua) in coastal Labrador. A total of 141 individuals, collected from offshore sites and from a coastal site within Gilbert Bay, Labrador, were genotyped using an ~11k single nucleotide polymorphism array. Analyses of population structure revealed strong genetic differentiation between migratory offshore cod and nonmigratory Gilbert Bay cod. Genetic differentiation was elevated for loci within a chromosomal rearrangement found on linkage group 1 (LG1) that coincides with a previously found double inversion associated with migratory and nonmigratory ecotype divergence of cod in the northeast Atlantic. This inverted region includes several genes potentially associated with adaptation to differences in salinity and temperature, as well as influencing migratory behaviour. Our work provides evidence that a chromosomal rearrangement on LG1 is associated with parallel patterns of divergence between migratory and nonmigratory ecotypes on both sides of the Atlantic Ocean. PMID- 29193391 TI - Dihydromyricetin inhibits NLRP3 inflammasome-dependent pyroptosis by activating the Nrf2 signaling pathway in vascular endothelial cells. AB - Increasing evidence demonstrates that pyroptosis, pro-inflammatory programmed cell death, is linked to atherosclerosis; however, the underlying mechanisms remain to be elucidated. Dihydromyricetin (DHM), a natural flavonoid, was reported to exert anti-oxidative and anti-inflammatory bioactivities. However, the effect of DHM on atherosclerosis-related pyroptosis has not been studied. In the present study, palmitic acid (PA) treatment led to pyroptosis in human umbilical vein endothelial cells (HUVECs), as evidenced by caspase-1 activation, LDH release, and propidium iodide-positive staining; enhanced the maturation and release of proinflammatory cytokine IL-1beta and activation of the NLRP3 inflammasome; and markedly increased intracellular reactive oxygen species (ROS) and mitochondrial ROS (mtROS) levels. Moreover, NLRP3 siRNA transfection or treatment with inhibitors efficiently suppressed PA-induced pyroptosis, and pretreatment with total ROS scavenger or mtROS scavenger attenuated PA-induced NLRP3 inflammasome activation and subsequent pyroptosis. However, DHM pretreatment inhibited PA-induced pyroptotic cell death by increasing cell viability, decreasing LDH and IL-1beta release, improving cell membrane integrity, and abolishing caspase-1 cleavage and subsequent IL-1beta maturation. We also found that DHM pre-treatment remarkably reduced the levels of intracellular ROS and mtROS and activated the Nrf2 signaling pathway. Moreover, knockdown of Nrf2 by siRNA abrogated the inhibitory effects of DHM on ROS generation and subsequent PA-induced pyroptosis. Together, these results indicate that the Nrf2 signaling pathway plays a role, as least in part, in the DHM mediated improvement in PA-induced pyroptosis in vascular endothelial cells, which implies the underlying medicinal value of DHM targeting immune/inflammatory related diseases, such as atherosclerosis.

AB - Shell thickness dependent band-gap engineering of quasi type II core-shell material with higher carrier cooling time, lower interfacial defect states, and longer charge carrier recombination time can be a promising candidate for both photocatalysis and solar cell. In the present investigation, colloidal CdSe@CdS core-shells with different shell thickness (2, 4 and 6 monolayer CdS) were synthesized through hot injection method and have been characterized by high resolution transmission electron microscope (HRTEM) followed by steady state absorption and luminescence techniques. Ultrafast transient absorption (TA) studies suggest longer carrier cooling, lower interfacial surface states, and slower carrier recombination time in CdSe@CdS core-shell with increasing shell thickness. By TA spectroscopy, the role of CdS shell in power conversion efficiency (PCE) has been explained in detail. The measured PCE was found to initially increase and then decrease with increasing shell thickness. Shell thickness has been optimized to maximize the efficiency after correlating the shell controlled carrier cooling and recombination with PCE values and a maximum PCE of 3.88 % was obtained with 4 monolayers of CdS shell, which is found to be 57 % higher than compared to bare CdSe QDs. PMID- 29193393 TI - Modified first or second cervical nerve transplantation technique for the treatment of recurrent laryngeal neuropathy in horses. AB - BACKGROUND: In horses, the only established method for reinnervation of the larynx is the nerve-muscle pedicle implantation, whereas in human medicine, direct nerve implantation is a standard surgical technique for selective laryngeal reinnervation in human patients suffering from bilateral vocal fold paralysis. OBJECTIVES: (1) To describe a modified first or second cervical nerve transplantation technique for the treatment of recurrent laryngeal neuropathy (RLN) in horses and (2) evaluate the outcomes of reinnervation using direct nerve needle-stimulation of the first cervical nerve and exercising endoscopy before and after surgery. STUDY DESIGN: Case series. METHODS: Nerve transplantation surgery, in which the first or second cervical nerve is tunnelled through the atrophied left cricoarytenoideus dorsalis muscle, was performed in combination with ipsilateral laser ventriculocordectomy. Ultrasound-guided stimulation of the first cervical nerve at the level of the alar foramen was used to confirm successful reinnervation post-operatively. Exercising endoscopy was performed before and after surgery. The exercising RLN grade of the left arytenoid was blindly determined at the highest stride frequency for each examination. RESULTS: Surgery was performed in 17 client-owned animals with RLN. Reinnervation was confirmed by nerve stimulation and subsequent arytenoid abduction observed in 11 out of 12 cases between 4 and 12 months post-operatively. Fourteen horses had exercising endoscopy before and after surgery. Nine horses had an improved exercising RLN grade, four horses had the same exercising grade and one horse had a worse exercising grade after surgery. MAIN LIMITATIONS: A sham-operated control group was not included and follow-up beyond 12 months and objective performance data were not obtained. CONCLUSIONS: The modified first or second cervical nerve transplantation technique, using tunnelling and direct implantation of the donor nerve into the cricoarytenoideus dorsalis muscle, resulted in reinnervation in 11 out of 12 cases and improved exercising grade in 9 out of 14 horses within 12 months after surgery. PMID- 29193396 TI - Recent Advances in Metallaaromatic Chemistry. AB - Metallaaromatics can be broadly defined as aromatic compounds in which one of the ring atoms is a transition metal. The metallabenzenes are one important class of these compounds that has undergone extensive study recently. Closely related species such as fused-ring metallabenzenes, heterometallabenzenes, pi-coordinated metallabenzenes and metallabenzynes have also attracted considerable attention. Although many metallaaromatics can be considered as metalla-analogues of classic organic aromatic compounds, this is not always the case. Recent seminal studies have shown that metallapentalenes and metallapentalynes, which are metalla analogues of the anti-aromatic compounds pentalene and pentalyne, are in fact aromatic and highly stable. Very unusual spiro-metallaaromatic compounds have also recently been isolated. In this concepts article, key features of all these intriguing metallaaromatic compounds are discussed with reference to the structural, spectroscopic, reactivity and theoretical studies that have been undertaken. These compounds continue to generate much interest, not only because of the contributions they make to fundamental chemical understanding, but also because of the promise of possible practical applications. PMID- 29193395 TI - Androgen and oestrogen receptors as potential prognostic markers for patients with ductal carcinoma in situ treated with surgery and radiotherapy. AB - Ductal carcinoma in situ (DCIS) is a heterogeneous disease that has been investigated less extensively than invasive breast cancer. Women with DCIS are mainly treated with conservative surgery almost exclusively followed by radiotherapy. However, as radiation treatment is not always effective, the search for biomarkers capable of identifying DCIS lesions that could progress to invasive cancer is ongoing. Although conventional biomarkers have been thoroughly studied in invasive tumours, little is known about the role played by androgen receptor (AR), widely expressed in DCIS. A series of 42 DCIS patients treated with quadrantectomy and radiotherapy were followed for a period of up to 95 months. Of these, 11 had recurrent DCIS or progressed to invasive cancer. All tumours were analysed for clinical pathological features. Conventional biomarkers and androgen receptor expression were determined by immunohistochemistry. Our results showed that AR was higher in tumours of relapsed patients than non relapsed patients (P value: 0.0005). Conversely, oestrogen receptor (ER) was higher, albeit not significantly, in non-relapsed patients than in relapsed patients. AR/ER ratio was considerably different in the two subgroups (P value: 0.0033). Area under the curve (AUC) values were 0.85 for AR and 0.80 for the AR/ER ratio. These preliminary results highlight the potentially important role of both AR and the AR/ER ratio as prognostic markers in DCIS. PMID- 29193397 TI - Nurses' preparedness for infectious disease outbreaks: A literature review and narrative synthesis of qualitative evidence. AB - AIMS AND OBJECTIVES: To explore the core components that constitute nurses' preparedness in an epidemic event. BACKGROUND: Healthcare service providers have worked to augment efforts to protect the public from the impact of epidemic events. While constituting the major healthcare taskforce, nurses are frequently tasked with fronting the response to an infectious disease outbreak. Given the crucial role of nurses in the management of prevailing epidemics, the constituents of their preparedness in epidemic events should be identified. DESIGN: A systematic search was undertaken to identify eligible studies from the literature. A narrative synthesis approach was employed to extract and synthesise findings of the reviewed qualitative studies. METHODS: Seven qualitative studies on nurses' experience and perceptions of epidemic events were examined for scientific quality using the Critical Appraisal Skills Programme Qualitative Checklist. Findings of these studies were synthesised adopting a narrative synthesis approach. RESULTS: Three interplaying themes were identified as follows: (i) personal resources, (ii) workplace resources and (iii) situational influences. The findings suggest that an effective epidemic outbreak response would require further effort to reinforce the interplay between individual nurses, healthcare institutions and the governments. CONCLUSIONS: The practical interplay among individual nurses, healthcare institutions and the governments is crucial in establishing an effective epidemic response. Further research on the understanding of the dynamic process of preparedness development is recommended to set future directions in research. RELEVANCE TO CLINICAL PRACTICE: This study offers important insights for devising future strategies in enhancing nurses' preparedness and response to an epidemic event. These include recommendations on providing education and training to nurses regarding infectious diseases, fostering institutional assistance and support in an outbreak and revising government policies and planning.

OBJECTIVES: To test the hypothesis in a nationwide population-based cohort study. METHODS: We used Danish medical registries to construct a cohort of all patients in Denmark with an operation code of tonsillectomy 1980-2010 (n = 195,169) and a matched age and sex general population comparison cohort (n = 975,845). Patients were followed until PD diagnosis, death, censoring, or end of follow-up 30 November 2013. Using Cox regression, we computed hazard ratios for PD and corresponding 95% confidence intervals, adjusting for age and sex by study design, and potential confounders. RESULTS: We identified 100 and 568 patients diagnosed with PD among the tonsillectomy and general population comparison cohort, respectively, finding similar risks of PD (adjusted hazard ratio = 0.95 [95% confidence interval: 0.76-1.19]; for > 20 years' follow-up (adjusted hazard ratio = 0.96 [95% confidence interval: 0.64-1.41]). CONCLUSION: Tonsillectomy is not associated with risk of PD, especially early-onset PD. (c) 2017 International Parkinson and Movement Disorder Society.

AB - Bis(ferrocenyl)germylene Fc*2 Ge: [2; Fc*=2,5-bis(3,5-di-tert-butylphenyl)-1 ferrocenyl] was isolated in the form of red crystals from the reaction of the sterically demanding ferrocenyl lithium dimer (Fc*Li)2 and GeI2 . Bis(ferrocenyl)germylene 2 exhibits extraordinary thermal stability in hydrocarbon solution and the solid state, as well as stable redox behavior. Moreover, it undergoes a ligand-redistribution reaction with GeCl2 ?(dioxane) to afford the corresponding chlorogermylene, which was isolated upon coordination with PBu3 .

AB - Tripterygium wilfordii Hook F (TwHF) is a promising Chinese traditional medicine used to significantly reduce proteinuria and improve renal function. However, its efficacy and safety in treatment of chronic kidney disease need to be further explored in order to promote its application in clinics. This review compared the efficacy and safety of TwHF with the placebo, conventional Western medicine and other immunosuppressive medicine in a range of kidney disorders. One hundred three randomized controlled trials were included. TwHF therapy decreased 24-hr proteinuria by 0.59 g/day (95% confidence interval [CI; -0.68, -0.50]), serum creatinine level by 1.93 MUmol/L (95% CI [-3.69, -0.17]), and blood urea nitrogen level by 0.24 mmol/L (95% CI [-0.41, -0.07]); increased the total effective rate by 27% (95% CI [1.24, 1.30]); and decreased the incidence of adverse reactions by 19% (95% CI [0.68, 0.96]) overall. Meta regression results showed that the duration of therapy and mean age of participants were the major sources of high heterogeneity. Sensitivity analysis demonstrated that our statistic results were relatively stable and credible. The present findings suggested that TwHF possibly has nephroprotective effects by decreasing proteinuria, serum creatinine level, and blood urea nitrogen level and no more adverse reactions compared with control group in most kidney disorders. However, these findings still need to be further confirmed by high-quality trials. PMID- 29193404 TI - Surgical treatment of the residual periodontal pocket. AB - The ultimate goal of periodontal therapy is to prevent further disease progression in order to reduce the risk of tooth loss. This objective can be achieved through a number of therapeutic modalities comprising both the nonsurgical and surgical phases of periodontal therapy. Nonsurgical periodontal treatment has been shown to control periodontal infection and to arrest progression of the disease in a significant number of cases. However, despite completion of nonsurgical treatment, a number of periodontal pockets, defined as 'residual', often remain. The presence of residual pockets may jeopardize tooth survival and be a risk factor of further disease progression, and ultimately tooth loss. Therefore, the aim of this review is to analyze the knowledge available on the indications for and the performance of periodontal surgical treatment of residual pockets in terms of 'traditional' (clinical, microbiological), patient-based and systemic health outcomes. PMID- 29193405 TI - Epigallocatechin-3-gallate enhances differentiation of acute promyelocytic leukemia cells via inhibition of PML-RARalpha and HDAC1. AB - The use of all-trans retinoic acid (ATRA) has dramatically improved the treatment and survival rate of patients with acute promyelocytic leukemia (APL). However, toxicity and resistance to this drug are major problems in the treatment of APL with ATRA. Earlier studies have suggested that the green tea polyphenol epigallocatechin gallate (EGCG) induces cell death in hematopoietic neoplasms without adversely affecting normal cells. In the present study, the potential therapeutic effect of EGCG in APL and the underlying molecular mechanisms were investigated. EGCG (100 MUM) significantly inhibited proliferation and induced apoptosis in HL-60 and NB4 cells. This effect was associated with decreased expressions of multidrug resistance proteins ABCB1, and ABCC1, whereas the expressions of pro-apoptotic genes CASP3, CASP8, p21, and Bax/Bcl-2 ratio were significantly increased. EGCG, at 25 MUM concentration, induced differentiation of leukemic cells towards granulocytic pattern in a similar manner to that observed for ATRA (1 MUM). Furthermore, EGCG suppressed the expression of clinical marker PML/RARalpha in NB4 cells and reduced the expression of HDAC1 in leukemic cells. In conclusion, the results suggested that EGCG can be considered as a potential treatment for APL.

AB - The aims of this study were to implement a magnetic resonance spectroscopy (MRS) protocol for the online profiling of subnanomolar quantities of metabolites sampled from the extracellular fluid using implanted microdialysis and to apply this protocol in glioma-bearing rats for the quantification of lactate concentration and the measurement of time-varying lactate concentration during drug administration. MRS acquisitions on the brain microdialysate were performed using a home-built, proton-tuned, microsolenoid with an active volume of 2 MUL. The microcoil was placed at the outlet of the microdialysis probe inside a preclinical magnetic resonance imaging (MRI) scanner. C6-bearing rats were implanted with microdialysis probes perfused with artificial cerebrospinal fluid solution and the lactate dehydrogenase (LDH) inhibitor oxamate. Microcoil magnetic resonance spectra were continuously updated using a single-pulse sequence. Localized in vivo spectra and high-resolution spectra on the dialysate were also acquired. The limit of detection and limit of quantification per unit time of the lactate methyl peak were determined as 0.37 nmol/?min and 1.23 nmol/?min, respectively. Signal-to-noise ratios (SNRs) of the lactate methyl peak above 120 were obtained from brain tumor microdialysate in an acquisition time of 4 min. On average, the lactate methyl peak amplitude measured in vivo using the nuclear magnetic resonance (NMR) microcoil was 193 +/- 46% higher in tumor dialysate relative to healthy brain dialysate. A similar ratio was obtained from high-resolution NMR spectra performed on the collected dialysate. Following oxamate addition in the perfusate, a monotonic decrease in the lactate peaks was observed in all animals with an average time constant of 4.6 min. In the absence of overlapping NMR peaks, robust profiling of extracellular lactate can be obtained online using a dedicated sensitive NMR microcoil. MRS measurements of the dynamic changes in lactate production induced by anti-tumoral drugs can be assessed accurately with temporal resolutions on the order of minutes. The MRS protocol can be readily transferred to the clinical environment with the use of suitable clinical microdialysis probes. PMID- 29193408 TI - Threatened fertility: A longitudinal study exploring experiences of fertility and having children after cancer treatment. AB - Infertility is a recognised potential sequel of cancer treatment which impacts negatively on the quality of survival. The aim of this study was to explore how men and women experience the threat of infertility by cancer treatment and individuals' thoughts about having children after cancer during the first 2 years following diagnosis. Nine women and seven men (aged 24-41) participated in two interviews in this longitudinal interview study, after the initiation of cancer treatment and 2 years thereafter. The interviews focused on participants' thoughts and feelings about threatened fertility and having children. The interviews were analysed with qualitative content analysis with a particular focus on identifying experiences over time. The Traits-Desires-Intentions model was used to reflect upon the study findings. The analysis resulted in the identification of four themes: Continue calmly on chosen path, Abandoning plans for children, Avoiding the subject of fertility and Struggling towards life goals. The results emphasise the need to offer individualised fertility-related treatment communication and counselling, both at the time of cancer diagnosis and also in connection with follow-up care. Appropriate fertility-related communication should be included in young cancer patients' survivor care plans. PMID- 29193407 TI - Thermodynamic secrets of multidrug resistance: A new take on transport mechanisms of secondary active antiporters. AB - Multidrug resistance (MDR) presents a growing challenge to global public health. Drug extrusion transporters play a critical part in MDR; thus, their mechanisms of substrate recognition are being studied in great detail. In this work, we review common structural features of key transporters involved in MDR. Based on our membrane potential-driving hypothesis, we propose a general energy-coupling mechanism for secondary-active antiporters. This putative mechanism provides a common framework for understanding poly-specificity of most-if not all-MDR transporters. PMID- 29193409 TI - More insights into the pharmacological effects of artemisinin. AB - Artemisinin is one of the most widely prescribed drugs against malaria and has recently received increased attention because of its other potential biological effects. The aim of this review is to summarize recent discoveries of the pharmaceutical effects of artemisinin in basic science along with its mechanistic action, as well as the intriguing results of recent clinical studies, with a focus on its antitumor activity. Scientific evidence indicates that artemisinin exerts its biological activity by generating reactive oxygen species that damage the DNA, mitochondrial depolarization, and cell death. In the present article review, scientific evidence suggests that artemisinin is a potential therapeutic agent for various diseases. Thus, this review is expected to encourage interested scientists to conduct further preclinical and clinical studies to evaluate these biological activities. PMID- 29193410 TI - An integrative review of rural and remote nursing graduate programmes and experiences of nursing graduates. AB - AIMS AND OBJECTIVES: To examine international studies that specifically focus on transition to practice for graduate registered nurses in rural and remote areas. BACKGROUND: Supportive graduate nursing programmes are essential for enabling nursing graduates' transition to practice and reducing attrition rates. Literature examining support measures for nursing graduates within metropolitan areas is abundant. However, there is a paucity of evidence on effective graduate programmes for rural and remote-based nursing graduates. DESIGN: A systematic approach was used to identify robust research within appropriate electronic databases. METHOD: Eligible articles were critically reviewed using the Mixed Method Appraisal Tool critical appraisal tool. Eligible articles were thematically analysed using the Braun and Clark approach. RESULTS: Eight articles met the selection criteria for inclusion. Findings revealed that while most graduate nurses survived the transition process, they often felt overwhelmed and abandoned with intense feelings of frustration. Many suffered transition shock and did not feel ready for the role. Socialisation of graduates to the clinical environment was lacking. Support offered in many graduate programmes was ad hoc and unstructured. Senior staff were inadequately supported in their roles as preceptors to assist with the transition. Critical support measures recommended included both debrief sessions and regular one-on-one support. CONCLUSIONS: Graduate programmes need to be structured yet flexible to accommodate the needs of rural and remote nurse graduates. Graduates need to be transitioned into practice with decremental support processes for both workloads and education. Preceptors require education on how to mentor before they can provide the appropriate support for graduates. Without these measures in place, a decrease in transition shock may not be possible. RELEVANCE TO CLINICAL PRACTICE: Graduate programmes need to be structured yet flexible, including assistance with both clinical skills and socialisation. Senior staff require education before they can adequately support new graduates. PMID- 29193411 TI - A systematic review of the anti-obesity and weight lowering effect of ginger (Zingiber officinale Roscoe) and its mechanisms of action. AB - Recently, the beneficial effects of ginger on obesity is taken into consideration. Albeit, it seems that the anti-obesity effect of ginger and its mechanism of action has not yet been reviewed. Therefore, the aim of this study was to systematically review the effect of Zingiber officinale Roscoe on obesity management. Databases including PubMed, Scopus, Google scholar, and Science Direct were searched from 1995 until May 2017 using the definitive keywords. Searching was limited to articles with English language. All of the relevant human and animal studies and also in vitro studies were included. Review articles, abstract in congress, and also other varieties of ginger were excluded. Eligibility of included articles were evaluated by 3 reviewers, which also extracted data. Articles were critically assessed individually for possible risk of bias. Twenty-seven articles (6 in vitro, 17 animal, and 4 human studies) were reviewed. Most of the experimental studies supported the weight lowering effect of ginger extract or powder in obese animal models, whereas the results of the available limited clinical studies showed no changes or slight changes of anthropometric measurements and body composition in subjects with obesity. Ginger could modulate obesity through various potential mechanisms including increasing thermogenesis, increasing lipolysis, suppression of lipogenesis, inhibition of intestinal fat absorption, and controlling appetite. This review article provides some convincing evidence to support the efficacy of ginger in obesity management and demonstrates the importance of future clinical trials. PMID- 29193412 TI - Role of resveratrol in regulation of cellular defense systems against oxidative stress. AB - Resveratrol, a natural polyphenolic compound, is found in various kinds of fruits, plants, and their commercial products such as red wine. It has been demonstrated to exhibit a variety of health-promoting effects including prevention and/or treatment of cardiovascular diseases, inflammation, diabetes, neurodegeneration, aging, and cancer. Cellular defensive properties of resveratrol can be explained through its ability of either directly neutralizing reactive oxygen species/reactive nitrogen species (ROS/RNS) or indirectly upregulating the expression of cellular defensive genes. As a direct antioxidant agent, resveratrol scavenges diverse ROS/RNS as well as secondary organic radicals with mechanisms of hydrogen atom transfer and sequential proton loss electron transfer, thereby protecting cellular biomolecules from oxidative damage. Resveratrol also enhances the expression of various antioxidant defensive enzymes such as heme oxygenase 1, catalase, glutathione peroxidase, and superoxide dismutase as well as the induction of glutathione level responsible for maintaining the cellular redox balance. Such defenses could be achieved by regulating various signaling pathways including sirtuin 1, nuclear factor erythroid 2-related factor 2 and nuclear factor kappaB. This review provides current understanding and information on the role of resveratrol in cellular defense system against oxidative stress. (c) 2017 BioFactors, 44(1):36-49, 2018. PMID- 29193413 TI - Imaging brain microstructure with diffusion MRI: practicality and applications. AB - This article gives an overview of microstructure imaging of the brain with diffusion MRI and reviews the state of the art. The microstructure-imaging paradigm aims to estimate and map microscopic properties of tissue using a model that links these properties to the voxel scale MR signal. Imaging techniques of this type are just starting to make the transition from the technical research domain to wide application in biomedical studies. We focus here on the practicalities of both implementing such techniques and using them in applications. Specifically, the article summarizes the relevant aspects of brain microanatomy and the range of diffusion-weighted MR measurements that provide sensitivity to them. It then reviews the evolution of mathematical and computational models that relate the diffusion MR signal to brain tissue microstructure, as well as the expanding areas of application. Next we focus on practicalities of designing a working microstructure imaging technique: model selection, experiment design, parameter estimation, validation, and the pipeline of development of this class of technique. The article concludes with some future perspectives on opportunities in this topic and expectations on how the field will evolve in the short-to-medium term. PMID- 29193414 TI - Exploring the intervention effect moderators of a cardiovascular health promotion study among rural African-Americans. AB - OBJECTIVE: The purpose of this analysis was to examine the participant characteristics that served as intervention effect moderators of a cardiovascular health promotion intervention study. DESIGN AND SAMPLE: This exploratory study was a secondary analysis of data collected during a cluster randomized controlled trial. The participants (n = 229) of the study were African-American adults recruited from 12 rural churches that were randomized to intervention (n = 6) and control (n = 6) groups. There were 115 individual participants in the intervention group, and 114 in the control group. MEASURES: Cardiovascular health intentions, attitudes, norms, and self-efficacy for produce consumption, dietary fat intake, and exercise were measured to test the effect of the intervention. Linear mixed model was used to detect intervention effect moderators. RESULTS: Personal heart disease status was a moderator of intervention effects for intentions, norms, and self-efficacy regarding dietary fat intake and attitudes about produce consumption. Lacking a family heart disease history was a moderator for dietary fat intake self-efficacy, and age was a dietary fat norms moderator. CONCLUSIONS: Knowledge about the moderators that influenced intervention outcomes can assist public health nurses in tailoring health promotion programs for underserved populations that can be implemented in community settings. PMID- 29193415 TI - Estimating the arterial input function from dynamic contrast-enhanced MRI data with compensation for flow enhancement (I): Theory, method, and phantom experiments. AB - BACKGROUND: The arterial input function (AIF) represents the time-dependent arterial contrast agent (CA) concentration that is used in pharmacokinetic modeling. PURPOSE: To develop a novel method for estimating the AIF from dynamic contrast-enhanced (DCE-) MRI data, while compensating for flow enhancement. STUDY TYPE: Signal simulation and phantom measurements. PHANTOM MODEL: Time-intensity curves (TICs) were simulated for different numbers of excitation pulses modeling flow effects. A phantom experiment was performed in which a solution (without CA) was passed through a straight tube, at constant flow velocity. FIELD STRENGTH/SEQUENCE: Dynamic fast spoiled gradient echo (FSPGRs) at 3T MRI, both in the simulations and in the phantom experiment. TICs were generated for a duration of 373 seconds and sampled at intervals of 1.247 seconds (300 timepoints). ASSESSMENT: The proposed method first estimates the number of pulses that spins have received, and then uses this knowledge to accurately estimate the CA concentration. STATISTICAL TESTS: The difference between the median of the estimated number of pulses and the true value was determined, as well as the interquartile range (IQR) of the estimations. The estimated CA concentrations were evaluated in the same way. The estimated number of pulses was also used to calculate flow velocity. RESULTS: The difference between the median estimated and reference number of pulses varied from -0.005 to -1.371 (corresponding IQRs: 0.853 and 48.377) at true values of 10 and 180 pulses, respectively. The difference between the median estimated CA concentration and the reference value varied from -0.00015 to 0.00306 mmol/L (corresponding IQRs: 0.01989 and 1.51013 mmol/L) at true values of 0.5 and 8.0 mmol/l, respectively, at an intermediate value of 100 pulses. The estimated flow velocities in the phantom were within 10% of the reference value. DATA CONCLUSION: The proposed method accurately corrects the MRI signal affected by the inflow effect.

PMID- 29193416 TI - Healthcare professionals' knowledge and practice of physical activity promotion in cancer care: Challenges and solutions. AB - Limited research exists regarding healthcare professionals' knowledge and practice of physical activity promotion for cancer survivors in Ireland. There is also a lack of research identifying the barriers experienced by oncology professionals when promoting physical activity, or referring patients to community-based exercise programmes. This study aims to identify healthcare professionals' knowledge, barriers and practices in relation to physical activity promotion for cancer survivors, and to generate guidance regarding the optimisation of the referral process to community-based exercise programmes. Oncology healthcare professionals (n = 114) were invited to participate in two rounds of an online Delphi study. The response rates in rounds one and two were 38% (43/114) and 70% (30/43). Most respondents acknowledged the value of physical activity for cancer survivors (>=86%) and agreed that discussing physical activity with cancer patients was part of their role (88%). However, the majority of recommendations provided to patients did not align with the current physical activity guidelines. Strategies related to four themes that could optimise the referral process to community-based exercise programmes achieved consensus, including providing education to healthcare professionals and patients regarding the benefits of physical activity and the logistics and quality of programmes, and optimising the logistics of the referral process. PMID- 29193417 TI - Transforming nurse-patient relationships-A qualitative study of nurse self disclosure in mental health care. AB - AIMS AND OBJECTIVES: To describe what and why nurses self-disclose to patients in mental health care. BACKGROUND: Self-disclosure is common, but controversial and difficult to delineate. Extant research suggests that self-disclosure might have several potentially beneficial effects on therapeutic alliance and treatment outcome for patients in mental health care, but results are often mixed and limited by definitional inconsistencies. DESIGN: Multi-site study with purposive sampling and source triangulation. METHOD: Qualitative descriptive study including data from 16 nurses taking part in participant observation, individual interviews and focus group interviews. RESULTS: Separate analyses resulted in four themes addressing the research question of what nurses self-disclose, and one main theme and four subthemes addressing why nurses self-disclose. The content of self-disclosure was captured in the four themes: Immediate family, Interests and activities, Life experiences and Identity. In addition, results showed that disclosures were common among the nurses. Self-disclosure's potential to transform the nurse-patient relationship, making it more open, honest, close, reciprocal and equal, was the overarching reason why nurses shared personal information. The nurses also chose to self-disclose to share existential and everyday sentiments, to give real-life advice, because it felt natural and responsive to patients' question to do so. CONCLUSION: Nurse self-disclosure is common and cover a variety of personal information. Nurses have several reasons for choosing to self-disclose, most of which are connected to improving the nurse patient relationship. RELEVANCE TO CLINICAL PRACTICE: Self-disclosure controversy can make it difficult for nurses to know whether they should share personal information or not. Insights into the diversity of and reasons for nurse self disclosure can help with deliberations on self-disclosure. PMID- 29193418 TI - Causes and predictors of 30-day readmission after cardiovascular implantable electronic devices implantation: Insights from Nationwide Readmissions Database. AB - INTRODUCTION: Readmissions are a burden on health care resources and have negative impact on patients. Cardiovascular implantable electronic devices (CIEDs) are frequently used in the management of rhythm disorders and advanced heart failure. We assessed 30-day readmissions in patients admitted for CIED implantation in a sample of United States patients. METHODS: Data were extracted from Nationwide Readmissions Database for calendar year 2013. Patients admitted for CIED implantation were identified using ICD-9 codes. Patients <18 years of age, with missing data, who died during hospitalization or discharged in December were excluded. Primary endpoint was all-cause 30-day readmission rate. Factors associated with 30-day readmissions were identified and examined using multivariate logistic regression. RESULTS: We identified 320,783 admissions for CIED implantations. After applying exclusion criteria, 290,420 patients were included in final analysis, out of whom 45,467 (15.7%) patients were readmitted within 30 days. Readmitted patients were younger and had more comorbidities. Septicemia (5.1%), pneumonia (3.4%), CHF (2.35%), and paroxysmal ventricular tachycardia (2.3%) were common primary causes of 30-day readmission. Young age, female gender, key comorbidities, weekend admissions, and admission to medium and large size hospital were independent predictors of 30-day readmissions. CONCLUSION: In our study, 15.7% patients were readmitted within 30 days of an index admission for CIED implantation. Most readmissions were due to infectious or cardiovascular causes. There is a need to identify patients at risk for readmission to improve outcomes and curb the cost of care.

AB - The metabolic syndrome (MetS) is a multicomponent condition with a complex etiology involving genetic and environmental factors. Artichoke leaf extract (ALE) has shown favorable effects on lipid and glucose metabolism. The present study aimed to investigate the effects of ALE supplementation on metabolic parameters in women with MetS, using a nutrigenetics approach. In this double blind randomized clinical trial, 50 women (aged 20-50 years) with MetS were randomly allocated into the two groups: "ALE group" (received 1,800 mg hydroalcoholic extract of artichoke as four tablets per day) and "placebo group" (received placebo consisted of corn starch, lactose, and avicel as four tablets per day) for 12 weeks. The biochemical and anthropometric parameters were determined before and after the intervention. The FTO-rs9939609 and the TCF7L2 rs7903146 polymorphisms were genotyped by polymerase chain reaction-restriction fragment length polymorphism. In carriers of A allele of the FTO-rs9939609, ALE supplementation resulted in a statistically significant decrease in serum triglyceride level compared with placebo (-19.11% vs. 10.83%; p < .05), with no other significant differences between the two groups. The TCF7L2-rs7903146 polymorphism showed no interaction with response to ALE (p > .05). These findings suggest that ALE supplementation may improve serum triglyceride level in A allele genotype of FTO-rs9939609 polymorphism in women with MetS. PMID- 29193420 TI - Accessory neuropathy after sternotomy: Clinico-anatomical correlation supporting an inflammatory cause. AB - Inflammatory etiologies are becoming increasingly recognized as explanations of some neuropathies, especially those occurring in the perioperative period. Although "brachial neuritis" is known to affect extraplexal nerves, accessory nerve palsy following median sternotomy has been attributed to stretch on the nerve. To better elucidate stretch as a potential cause, a cadaveric study was performed. Two patients who developed accessory nerve palsy following median sternotomy are presented to illustrate features consistent with the diagnosis of a perioperative inflammatory neuropathy. Five adult unembalmed cadavers underwent exposure of the bilateral accessory nerves in the posterior cervical triangle. A median sternotomy was performed and self-retaining retractors positioned. With the head in neutral, left rotation and right rotation, retractors were opened as during surgery while observing and recording any accessory nerve movements. The self-retaining sternal retractors were fully opened to a mean inter-blade distance of 13 cm. Regardless of head position, from the initial retractor click to maximal opening there was no gross movement of the accessory nerve on the left or right sides. Opening self-retaining sternal retractors does not appear to stretch the accessory nerve in the posterior cervical triangle. Based on our clinical experience and cadaveric results, we believe that inflammatory conditions, (i.e., idiopathic brachial plexitis) can involve the accessory nerve, and might be triggered by surgical procedures.

AB - Pluta microscope used to throw light on the effect of heat treatment time on the different properties of poly (ethylene terephthalate) PET fibers. PET fibers were annealed at times ranged from 5 to 30 min at different temperatures (150, 170, 190, 210 degrees C) using two different processes (fast cooling and slow cooling processes) in air. The refractive indices, the shrinkage, orientation factor and crystallinity of PET fibers were determined for different annealing temperature during the short time treatment. The shrinkage percentage and degree of crystallinity increased with increasing the temperature and time of annealing. Microinterferograms are given for illustration. PMID- 29193423 TI - Assessing body awareness and autonomic reactivity: Factor structure and psychometric properties of the Body Perception Questionnaire-Short Form (BPQ-SF). AB - Body awareness and reactivity dysfunction are characteristic of a range of psychiatric disorders. Although the neural pathways communicating between the body and brain that contribute to these experiences involve the autonomic nervous system, few research tools for studying subjective bodily experiences have been informed by these neural circuits. This paper describes the factor structure, reliability, and convergent validity of the Body Awareness and Autonomic Reactivity subscales of the Body Perception Questionnaire-Short Form (BPQ-SF). Exploratory and confirmatory factor analyses were applied to data from three samples collected via the internet in Spain and the US and a college population in the US (combined n = 1320). Body awareness was described by a single factor. Autonomic reactivity reflected unique factors for organs above and below the diaphragm. Subscales showed strong reliability; converged with validation measures; and differed by age, sex, medication use, and self-reported psychiatric disorder. Post hoc analyses were used to create the 12-item Body Awareness Very Short Form. Results are discussed in relation to the distinct functions of supra- and sub-diaphragmatic autonomic pathways as proposed by the Polyvagal Theory and their potential dysfunction in psychiatric disorders. PMID- 29193424 TI - Oral cancer databases: A comprehensive review. AB - Cancer database is a systematic collection and analysis of information on various human cancers at genomic and molecular level that can be utilized to understand various steps in carcinogenesis and for therapeutic advancement in cancer field. Oral cancer is one of the leading causes of morbidity and mortality all over the world. The current research efforts in this field are aimed at cancer etiology and therapy. Advanced genomic technologies including microarrays, proteomics, transcrpitomics, and gene sequencing development have culminated in generation of extensive data and subjection of several genes and microRNAs that are distinctively expressed and this information is stored in the form of various databases. Extensive data from various resources have brought the need for collaboration and data sharing to make effective use of this new knowledge. The current review provides comprehensive information of various publicly accessible databases that contain information pertinent to oral squamous cell carcinoma (OSCC) and databases designed exclusively for OSCC. The databases discussed in this paper are Protein-Coding Gene Databases and microRNA Databases. This paper also describes gene overlap in various databases, which will help researchers to reduce redundancy and focus on only those genes, which are common to more than one databases. We hope such introduction will promote awareness and facilitate the usage of these resources in the cancer research community, and researchers can explore the molecular mechanisms involved in the development of cancer, which can help in subsequent crafting of therapeutic strategies.

AB - Using a combination of population- and individual-based analytical approaches, we provide a comprehensive examination of genetic connectivity of Dungeness crab (Cancer magister) along ~1,200 km of the California Current System (CCS). We sampled individuals at 33 sites in 2012 to establish a baseline of genetic diversity and hierarchal population genetic structure and then assessed interannual variability in our estimates by sampling again in 2014. Genetic diversity showed little variation among sites or across years. In 2012, we observed weak genetic differentiation among sites (FST range = -0.005-0.014) following a pattern of isolation by distance (IBD) and significantly high relatedness among individuals within nine sampling sites. In 2014, pairwise FST estimates were lower (FST range = -0.014-0.007), there was no spatial autocorrelation, and fewer sites had significant evidence of relatedness. Based on these findings, we propose that interannual variation in the physical oceanographic conditions of the CCS influences larval recruitment and thus gene flow, contributing to interannual variation in population genetic structure. Estimates of effective population size (Ne ) were large in both 2012 and 2014. Together, our results suggest that Dungeness crab in the CCS may constitute a single evolutionary population, although geographically limited dispersal results in an ephemeral signal of IBD. Furthermore, our findings demonstrate that populations of marine organisms may be susceptible to temporal changes in population genetic structure over short time periods; thus, interannual variability in population genetic measures should be considered. PMID- 29193428 TI - Amalgamation of Marginal Gains (AMG) as a potential system to deliver high quality fundamental nursing care: A qualitative analysis of interviews from high performance AMG sports and healthcare practitioners. AB - AIMS AND OBJECTIVES: To investigate the components of the Amalgamation of Marginal Gains (AMG) performance system to identify a set of principles that can be built into an innovative fundamental nursing care protocol. BACKGROUND: Nursing is urged to refocus on its fundamental care activities, but little evidence exists to guide practising nurses. Fundamental care is a combination of many small behaviours aimed at meeting a person's care needs. AMG is a successful system of performance management that focusses on small (or marginal) gains, and might provide a new delivery framework for fundamental nursing care. DESIGN: Qualitative interview study. METHODS: We undertook in-depth interviews with healthcare and sports professionals experienced in AMG. We analysed data using open coding in a framework analysis, and then interrogated the data using Normalisation Process Theory (NPT). We triangulated findings with AMG literature to develop an intervention logic model. RESULTS: We interviewed 20 AMG practitioners. AMG processes were as follows: focusing on many details to optimise performance, identification of marginal gains using different sources, understanding current versus optimum performance, monitoring at micro and macro level and strong leadership. Elements of normalisation were as follows: whole team belief in AMG to improve performance, a collective desire for excellence using evidence-based actions, whole team engagement to identify choose and implement changes, and individual and group responsibility for monitoring performance. CONCLUSIONS: We have elicited the processes described by AMG innovators in health care and sport and have mapped the normalisation potential and work required to embed such a system into nursing practice. RELEVANCE TO CLINICAL PRACTICE: The development of our logic model based on AMG and NPT may provide a practical framework for improving fundamental nursing care and is ripe for further development and testing in clinical trials.

AB - BACKGROUND: Information regarding masticatory muscle function in children with cleft lip and palate (CLP) is limited. As a consequence, research on masticatory muscle activity in cleft subjects is needed. AIM: To assess masticatory muscle activity in children surgically treated for CLP as well as identify the possible factors associated with this activity. DESIGN: The sample comprised 82 children with mixed dentition and Class I occlusions (25 children with unilateral CLP and 57 subjects with no cleft abnormalities). A DAB-Bluetooth Instrument (Zebris Medical GmbH, Germany) was used to take electromyographical (EMG) recordings of the temporal and masseter muscles both in the mandibular rest position and during maximum voluntary contraction (MVC). RESULTS: Patients with clefts showed a significant increase in temporal muscle activity at rest compared with the controls. The presence of clefts and unilateral posterior crossbites are factors strongly associated with increased temporal muscle EMG potentials during rest position. CONCLUSIONS: Children with clefts have altered temporal muscle function. The presence of posterior crossbites affects the temporal muscle activity in cleft subjects. Early diagnosis and orthodontic treatment of malocclusions are necessary to achieve functional improvement in these patients.

AB - AIMS AND OBJECTIVES: To explore the experiences of clinical research nurses recruiting patients in a large specialist care-based cohort study. BACKGROUND: Longitudinal studies are vital to better understand the aetiology and moderators of health conditions. This need is especially salient for congenital conditions, such as cleft lip and/or palate, where establishing large, comprehensive data sets from birth is vital to improve understanding and to inform interventions. Various barriers exist in recruiting patients to large cohort studies. The role of clinical research nurses embedded within health settings has grown over past decades to facilitate data collection, yet challenges remain. DESIGN: Qualitative descriptive study. METHODS: Individual semi-structured interviews with 12 clinical research nurses based in 10 National Health Service cleft services across the UK, recruiting to the Cleft Collective Birth Cohort Study. RESULTS: Of seven emergent themes, three highlighted challenges to recruiting patients, another three described facilitative factors, and one theme overlapped challenges and facilitators. Challenges included the life circumstances of potential participants; language barriers; and limited clinical research nurse time for study. Facilitative factors included integrating research into clinical practice; patient information shared with clinical research nurses; and support from the university-based research study team. The theme "Method of data collection" related to both challenges and facilitators. CONCLUSIONS: The qualitative data from clinical research nurses recruiting to a large birth cohort study provide helpful practical detail for specialist healthcare teams, specialist nurses, clinical research nurses and researchers looking to optimise recruitment and data collection in longitudinal studies. RELEVANCE TO CLINICAL PRACTICE: The findings suggest the importance of specialist clinical services and research study teams cooperating to embed research into everyday clinical practice, without compromising care. This should facilitate patients' willingness to participate in important research like the Cleft Collective study and provide them with a positive experience of research.

AB - Human pluripotent stem cell-derived osteoblasts possess great potential for use in bone disorder elucidation and repair; however, while the general ability of human pluripotent stem cells to differentiate into osteoblasts and lay down bone specific matrix has been shown, previous studies lack the complete characterization of the process whereby such osteoblasts are derived as well as a comparison between the osteogenic efficiency of multiple cell lines. Here, we compared the osteogenic potential of two human induced pluripotent stem cell lines (RIV9 and RIV4) to human H9 embryonic stem cells. Generally capable of osteogenic differentiation, the overall osteogenic yield was lower in the RIV9 and RIV4 lines and correlated with differential expression of osteocalcin (OCN) in mature cultures and PAX7 and TWIST1 during early differentiation. In the undifferentiated cells, the promoters of the latter two genes were differentially methylated potentially explaining the variation in differentiation efficiency. Furthermore, the expression signatures of selected neural crest and mesodermal genes and proteins suggested that H9 cells preferentially gave rise to neural crest-derived osteoblasts, whereas the osteoblasts in the RIV9 cultures were generated both through a mesodermal and a neural crest route although each at a lower rate. These data suggest that epigenetic dissimilarities between multiple PSC lines may lead to differences in lineage derivation and mineralization. Since osteoblast progenitors from one origin inadequately repair a defect in the other, these data underscore the importance of screening human pluripotent stem cells lines for the identity of the osteoprogenitors they lay down.

AB - For the practical application of organic light emitting devices (OLEDs) based on thermally activated delayed fluorescence (TADF) for large area TV and solid state lighting, low power consumption as well as the operation lifetime at high brightness over 1000 cd m-2 must be improved. Here, we have developed a novel hexaphenylbenzene-based sterically bulky hole-transport layer named 4DBTHPB with deep ionization potential of 5.8 eV and high triplet energy of 2.7 eV. By using 4DBTHPB, we can realize a highly efficient and stable TADF OLED exhibiting external quantum efficiency of 21.6 % and power efficiency of 54.3 lm W-1 and operation lifetime at 50 % (LT50 ) of approximately 10 000 h at an initial luminance of 1000 cd m-2 . These performances are comparable to those of the state-of-the-art green phosphorescent OLEDs reported in the scientific literatures. PMID- 29193431 TI - Chemo- and Stereoselective Cross Rauhut-Currier-Type Reaction of Tri-substituted Alkenes Containing Trifluoromethyl Groups. AB - A chemoselective cross Rauhut-Currier-type reaction has been developed involving a tri-substituted alkene (trifluoromethyl-containing acrylonitrile derivative) with a di- or tri-substituted alkene to yield tetra-substituted double bonds in RC-type products. This approach can support the synthesis of trifluoromethylated tetra-substituted olefins and synthetically important, structurally complex 3 allylic-type oxindole skeletons. The asymmetric version of this RC-type reaction can be realized by combining a Bronsted acid and Lewis base for bifunctional H bonding-tertiary amine catalysis. Subsequent transformation of multi functionalized RC-type product leads to pharmacologically interesting cyclohexane based spiro-pyrazolones bearing six contiguous chiral centers and two highly congested, vicinal quaternary carbon centers. PMID- 29193432 TI - Spatial separation of FtsZ and FtsN during cell division. AB - The division of Escherichia coli is mediated by a collection of some 34 different proteins that are recruited to the division septum and are thought to assemble into a macromolecular complex known as 'the divisome'. Herein, we have endeavored to better understand the structure of the divisome by imaging two of its core components; FtsZ and FtsN. Super resolution microscopy (SIM and gSTED) indicated that both proteins are localized in large assemblies, which are distributed around the division septum (i.e., forming a discontinuous ring). Although the rings had similar radii prior to constriction, the individual densities were often spatially separated circumferentially. As the cell envelope constricted, the discontinuous ring formed by FtsZ moved inside the discontinuous ring formed by FtsN. The radial and circumferential separation observed in our images indicates that the majority of FtsZ and FtsN molecules are organized in different macromolecular assemblies, rather than in a large super-complex. This conclusion was supported by fluorescence recovery after photobleaching measurements, which indicated that the dynamic behavior of the two macromolecular assemblies was also fundamentally different. Taken together, the data indicates that constriction of the cell envelope is brought about by (at least) two spatially separated complexes.

PMID- 29193434 TI - Working in a storied way-Narrative-based approaches to person-centred care and practice development in older adult residential care settings. AB - AIMS AND OBJECTIVES: To evaluate the effects of the implementation of a methodological framework for a narrative-based approach to practice development and person-centred care in residential aged care settings. BACKGROUND: Care in long-term residential settings for older people is moving away from the biomedical approach and adopting a more person-centred one. Narrative can help shape the way care is planned and organised. The provision of person-centred care that is holistic and that takes account of resident's beliefs and values can be enhanced by incorporating narrative approaches to care within a practice development framework. DESIGN: The chosen methodology was participatory action research. METHODS: Between 2010-2014, a methodological framework of narrative practice was implemented in two residential care settings, comprising 37 residents and 38 staff, using an action research approach. Three action cycles: (i) narrative practice and culture identification, (ii) developing narrative practice and (iii) working in a storied way emerged during the implementation. RESULTS: Key outcomes emerged in relation to the findings. These were based on narrative being, knowing and doing and centred around the key outcomes of (i) how people responded to change (narrative being), (ii) the development of shared understandings (narrative knowing) and (iii) intentional action (narrative doing). CONCLUSION: The implementation of a framework of narrative practice demonstrated that how people respond to change, the development of shared understandings and intentional action were interrelated and interlinked. It illustrated the importance of ensuring that practice context is taken account of in the implementation of action research and the importance of ensuring that narrative being, knowing and doing are clear and understandable for change to occur. RELEVANCE TO CLINICAL PRACTICE: Implementation of a narrative approach to care can develop new ways of working that value biography and promote the development of a co-constructed plan of care. PMID- 29193435 TI - Violent Poly-Victimization: The Longitudinal Patterns of Physical and Emotional Victimization Throughout Adolescence (11-17 Years). AB - In this study, we aimed to characterize developmental patterns of poly victimization in a normative sample of adolescents by applying longitudinal latent class analysis. Using the four most recent waves of data from the Zurich Project on the Social Development of Children and Youths (z-proso), we identified three classes, or separate groups, of youths with distinct patterns of victimization from age 11 to 17. The largest class represented young people who were least likely to be victimized in any way and at any time. The two smaller groups represented different types of poly-victimization-a non-parental and a long-term parental victimization group. Adolescents in the two groups differed both in the number as well as type of victimization that they experienced at different times. Moreover, class membership also had implications for different mental health outcomes. PMID- 29193436 TI - Editorial preface to special issue. PMID- 29193437 TI - Silencing of gelatinase expression delays myoblast differentiation in vitro. AB - Skeletal muscle growth and regeneration relies on the activation of muscle specific stem cells, that is, satellite cells. The activation and differentiation of satellite cells into myoblasts, as well as their migration, proliferation, and fusion of mononuclear myoblasts into a functional multi-nucleated muscle fiber, are associated with extracellular matrix (ECM) protein synthesis and degradation. The extracellular environment is dynamically adapting to the changes accompanying skeletal muscle growth or repair. Enzymes engaged in many biological processes that involve ECM remodeling are matrix metalloproteinases (MMPs). Among metalloproteinases crucial for skeletal muscles are two gelatinases-MMP-9 and MMP 2. In the current study we test the effect of silencing the MMP-9 and MMP-2 expression on the proliferation and differentiation of in vitro cultured skeletal muscle myoblasts. We show that downregulating gelatinase MMP-9 expression results in a delayed myoblast differentiation. PMID- 29193439 TI - Jackhammer esophagus: Assessing the balance between prepeak and postpeak contractile integral. AB - BACKGROUND: We hypothesized that symptoms in Jackhammer esophagus (JH) are associated with an imbalance between the prepeak and postpeak phases of contraction. Thus, we developed a method to distinguish the contractile integral components of prepeak and postpeak phase contractile activity to determine the contribution of each phase and their association with dysphagia. METHODS: Patients diagnosed with JH were enrolled and compared to controls. The first five intact swallows during manometry were analyzed. A single swallow was divided into a prepeak and postpeak phase. The contractile integral of each phase and its corresponding time-controlled integral were computed. All metrics were compared between controls and JH patients subcategorized by the impaction dysphagia question (IDQ) score with cut-off of 6. KEY RESULTS: Thirty eight JH patients and 71 controls were included. Twelve JH patients had IDQ <= 6 and 26 with IDQ > 6. JH patients had higher contractile integral in both phases, and a higher ratio between postpeak to prepeak contractile integral independent of duration. Similarly, JH patients with an IDQ > 6 had higher contractile metrics than those with IDQ <= 6. There was a correlation between the IDQ score and the ratio within the postpeak to prepeak contractile integral (r = .375). CONCLUSIONS: Abnormalities in contractile integral of the postpeak phase are more significant in JH with higher dysphagia scores Although the total postpeak contractile integral was higher in symptomatic patients, this was associated with longer duration of postpeak activity suggesting that dysphagia patients with JH have a defect in the postpeak phase of peristalsis. PMID- 29193438 TI - Routine practice in staffed community accommodation (approved premises) in England and Wales: Quantitative benchmarking from the first year of a longitudinal study. AB - BACKGROUND: In England and Wales, 'approved premises' offer 24-hour staffed accommodation for high-risk offenders, most of whom are returning to the community from prison. With a move towards a standardised operating model, it is essential to be able to measure outcomes. AIMS: Our aim is to collate and evaluate 'benchmarks' for approved premises. METHODS: A cross-sectional, descriptive design was used to establish the impact of existing practice in all four approved premises in Wales. Data on well-being, life satisfaction, attitudes to violence and problem-solving abilities were recorded with 114 male residents (of 486), and attitudes to personality disorder and personal well-being/burnout with 30 staff (of 86), in both narrative style and according to a number of scales used within criminal justice and healthcare systems. Perceptions of environmental climate were assessed with both groups. Scores were compared with those from reference groups, including prisoners and secure hospital patients. Criminological outcomes (e.g. prison recall) were obtained for all 486 men. RESULTS: Scores on the scales used were broadly comparable with those in relevant reference groups, but some showed floor or ceiling effects. Recall rates, whether directly from the premises or after further onward movement, were about 42% overall, comparable with those reported for similar offenders elsewhere. CONCLUSIONS: This paper provides a short battery of measurements for use as benchmarks of experience and outcomes in staffed community accommodation for high risk men.

PMID- 29193440 TI - Mid-term outcomes and complications of total knee arthroplasty in haemophilic arthropathy: A review of consecutive 131 knees between 2006 and 2015 in a single institute. AB - INTRODUCTION: Although total knee arthroplasty (TKA) in haemophilic arthropathy can reduce severe joint pain and improve functional disability, it is technically demanding. AIM: To evaluate mid-term outcomes and complications of TKA in haemophilic arthropathy. METHODS: This study retrospectively reviewed 131 consecutive primary TKAs in a single institute. The mean age was 41.0 years old, and the mean follow-up period was 6.8 years. Clinical and radiographic results were evaluated. Complications were categorized according to the classification system of the Knee Society for TKA complications. RESULTS: The average Western Ontario and McMaster Universities Arthritis Index (WOMAC) score improved from 66.0 to 24.2. The average flexion contracture significantly decreased from 17.3 degrees to 4.7 degrees , but the average pre- and postoperative maximum flexion did not differ (80.9 degrees vs 85.6 degrees , respectively). The average mechanical axis was varus 5.2 degrees preoperatively and valgus 0.3 degrees postoperatively. The coronal positions of the femoral and tibial components and the sagittal positions of these components were within +/-3 degrees in 83.2%, 89.3%, 63.4% and 73.3% of cases, respectively. Complications occurred in 17 knees (13.0%): hemarthrosis (n = 7), medial collateral ligament injury (n = 1), stiffness (n = 2), deep periprosthetic joint infection (PJI) (n = 3) and periprosthetic fracture (n = 4). CONCLUSIONS: The mid-term results of TKA in haemophilic arthropathy were satisfactory in pain relief, improved function and decreased flexion contracture. Bleeding and PJI continue to be major concerns for TKA in haemophilic arthropathy, and risk of periprosthetic fracture must be taken into account for patient education and appropriate prevention. PMID- 29193441 TI - Therapy for antiphospholipid miscarriages: Throwing the baby out with the bathwater? AB - PROBLEM: The association of low molecular weight heparin (LMWH) with low-dose aspirin (LDASA) provides the therapeutic cornerstone of obstetric anti phospholipid syndrome (APS). This combo approach is not effective in all patients, and few women still experience recurrences. METHOD OF STUDY: In an elegant in vitro study, Chiombori Quao and colleagues demonstrated that anti phospholipid antibodies (aPL) affect the functionality of endometrial endothelial cells interfering with angiogenesis. LMWH and LDASA, in combination or alone, did not display any protective activity but exacerbated aPL-mediated effects. RESULTS: The above data were advocated as a demonstration of the inefficacy of LMWH and LDASA in obstetric APS. Given the lack of thrombotic lesions in APS placentae, this treatment is mainly empirical. However, clinical practice clearly shows that LMWH and LDASA are effective in most patients. Non-responsive women represent a peculiar subgroup, with a high-risk aPL profile. All experimental models, including in vitro models of obstetric APS, display limitations that should be considered before translating data to patients. In particular, the use of a monoclonal antibody specific for Domain (D) 5 does not fit with the evidence that anti-D1, but not anti-D4,5, are associated with both vascular and obstetric APS manifestations. CONCLUSION: The association of LMWH and LDASA is the most effective therapeutic option for pregnant aPL-positive women. The lack of a clear demonstration of the pharmacological action of LMWH/LDASA should urge to further invtrestigate the pathophysiology of aPL-associated miscarriages.

AB - The native shape and intracellular distribution of newly synthesized DNA was visualized by correlative (light and electron) microscopy in ice embedded whole cells of Escherichia coli. For that purpose, the commercially available modified nucleoside triphosphate named BODIPY(r) FL-14-dUTP was enzymatically incorporated in vivo into the genome of E. coli mutant K12 strain, which cannot synthesize thymine. The successful incorporation of this thymidine analogue was confirmed first by fluorescence microscope, where the cells were stained in the typical for bodipy green color. Later the preselected labeled E. coli were observed by Hilbert Differential Transmission Electron Microscope (HDC TEM) and the distribution of elemental boron (contained in bodipy) was visualized at high resolution by an electron spectroscopic imaging (ESI) technique. The practical detection limit of boron was found to be around 5 ~ 10 mmol/kg in area of 0.1 MUm2 , which demonstrated that ESI is a suitable approach to study the cytochemistry and location of labeled nucleic fragments within the cytoplasmic chromosomal area. In addition, the fine cellular fibrous and chromosomal ultrastructures were revealed in situ by combing of phase-plate HDC TEM and ESI. The obtained results conclude that the correlation between fluorescent microscopy with phase-plate HDC TEM and ESI is a powerful approach to explore the structural and conformation dynamics of DNA replication machinery in frozen cells close to the living state. PMID- 29193443 TI - A review of sleep disturbance in children and adolescents with anxiety. AB - The present review examines the relations between sleep disturbance and anxiety in children and adolescents. The review begins with a detailed discussion of normative developmental trends in sleep, and the relation between sleep quality and emotion dysregulation in children. The extant literature on sleep disturbance in clinically anxious children with a focus on subjective versus objective measures of sleep is then summarized in detail. Finally, a review of the reciprocal relationship between sleep and emotion regulation is provided. The available research suggests that sleep disturbance is quite prevalent in children with anxiety disorders, although the directionality of the association between sleep disturbance and anxiety in children remains unclear. Despite this limitation, a reciprocal relationship between sleep quality and anxiety appears to be well established. Research using objective measures of sleep quality (e.g. polysomnography, sleep actigraphy, sleep bruxism) is warranted to better understand this relation. Further, complicating factors such as the environment in which sleep quality is measured, the developmental stage of participants, varying severity of anxiety and the timeframe during which assessment takes place should all be considered when examining sleep disturbance in this population. PMID- 29193444 TI - Morin exerts neuroprotection via attenuation of ROS induced oxidative damage and neuroinflammation in experimental diabetic neuropathy. AB - Morin, a bioflavonoid with diverse pharmacological effects against various diseases; in most cases morin protective effects were attributed to its detoxifying effect against reactive oxygen species (ROS). Diabetic neuropathy (DN) is a chronic, debilitating neuronal pain associated with intense generation of free radicals and proinflammatory cytokine accumulation in peripheral neurons. We investigated the pharmacological effect of morin against metabolic excess mediated mitochondrial ROS generation and corresponding effect on Nrf2, NF-kappaB pathways in Streptozotocin (STZ)-induced diabetic rats and in high glucose insulted Mouse neuroblastoma cell line, Neuro 2A (N2A). Animals were evaluated for nerve function parameters, motor and sensory nerve conduction velocities (MNCV and SNCV) and nerve blood flow (NBF) followed by TUNEL and immunoblot analysis. Mitochondrial function was evaluated by performing JC-1 and MitoSOX assays in high glucose (30 mM) incubated N2A cells. Diabetic animals showed significant impairment in MNCV, SNCV, and NBF as well as increased pain hypersensitivity. However, oral administration of morin at 50 and 100 mg/kg improved SNCV, MNCV, and NBF and reduced sensorimotor alterations (hyperalgesia and allodynia) in diabetic animals. Studies in N2A cells have revealed that morin ameliorated the high glucose-induced mitochondrial superoxide production, membrane depolarization, and total ROS generation. Morin effectively counteracted NF-kappaB-mediated neuroinflammation by reducing ROS mediated IKK activation and increased Nrf2-mediated antioxidant defenses in high glucose-induced N2A cells. The results of our study suggest that morin has exquisite role in offering neuroprotection in experimental DN and further clinical investigation may reward in finding better alternative for the management of DN.

A controlled study using a moderation approach. AB - A growing body of research suggests that, compared to normative adolescence, adoptive adolescence could be considered a specific risk condition characterized by more psychiatric problems, attachment insecurity, and emotional regulation difficulties as consequences of negative experiences in preadoption relationships. The current study explores (a) a moderation model of adoption status on the association between attachment representations (secure, dismissing, preoccupied, and disorganized) and behavioural problems and (b) a moderation model of adoption status on the association between emotion regulation processes (cognitive reappraisal and expressive suppression) and behavioural problems. Both the moderation models were controlled for verbal skills. Forty-six adopted adolescents and a control group of 34 nonadopted peers (12-16 years old) living with both their biological parents were assessed using the Friends and Family Interview, the Emotion Regulation Questionnaire for Children and Adolescents, the Child Behaviour Check List 6-18, and the verbal subtests of the Wechsler Intelligence Scale for Children, the latter as control measure. Results showed that adoption status (but not attachment) positively predicted externalizing and total behaviour problems, whereas attachment disorganization (but not adoption status) positively predicted internalizing problems in both group. Moreover, low cognitive reappraisal had a negative impact on externalizing problems only for adopted adolescents, but not for nonadopted youths. The clinical implications of these findings are discussed in order to enhance effective intervention with adopted adolescents and their parents. PMID- 29193447 TI - Increased severity of obstructive sleep apnea is associated with less anxiety and depression. AB - The objective was to investigate symptoms of depression and anxiety in relation to the presence and severity of obstructive sleep apnea (OSA) among patients referred with suspicion of OSA. The sample comprised 3770 consecutive patients with a mean age of 49.1 years; 69.7% were male. OSA was diagnosed and categorized based on a standard respiratory polygraphic sleep study using a type 3 portable monitor. Patients completed the validated Hospital Anxiety and Depression Scale (HADS) prior to the sleep study. In addition, they answered questions about whether they were currently in treatment for mental disorders and whether they had been diagnosed previously with depression. We adjusted for sex, age, smoking, alcohol consumption and obesity in the logistic regression analyses. In total, 35.1% had apnea-hypopnea index (AHI) < 5 (no OSA), 31.9% had AHI: 5-14.9 (mild OSA), 17.3% had AHI: 15-29.9 (moderate OSA) and 15.7% had AHI >= 30 (severe OSA). The prevalence of anxiety and depressive symptoms were significantly lower with increased OSA severity, and also when adjusting for sex, age, smoking, alcohol consumption and obesity (AHI >= 15 as dependent variable). Similarly, currently being in treatment for mental disorders and being diagnosed previously with depression were both associated negatively with OSA severity, with only the latter remaining significant in the fully adjusted model. Furthermore, multiple linear regressions showed that HADS anxiety and depression total scores were associated negatively with AHI. In conclusion, symptoms of anxiety and depression were associated negatively with OSA severity in these referred patients. The findings remained significant also after adjusting for several relevant confounders. PMID- 29193446 TI - A distinct mechanism of senescence activation in amnion epithelial cells by infection, inflammation, and oxidative stress. AB - PROBLEM: We investigated p38MAPK activation-induced fetal membrane cell senescence in response to inflammation (tumour necrosis factor-alpha [TNF-alpha]) and infection (lipopolysaccharide [LPS]), factors associated with spontaneous preterm birth. METHOD OF STUDY: Primary amnion epithelial cells (AECs) were exposed to TNF-alpha, 50 ng/mL and LPS, 100 ng/mL. Cigarette smoke extract (CSE), a known OS inducer, was used as positive control. AECs were cotreated with the antioxidant N-acetyl cysteine (NAC) and p38MAPK inhibitor SB203580 to determine the effect of OS and p38MAPK. Western blot analysis was performed for active (Phospho-p38MAPK) and total p38MAPK. Senescence was determined by flow cytometry, and culture supernatants were tested for IL-6 using ELISA. RESULTS: TNF-alpha, but not LPS, increased p38MAPK activation compared to untreated cells (P = .01). The number of senescent cells and senescence-associated IL-6 was higher in both TNF-alpha and LPS-treated cells compared to control (P = .001, P = .01, respectively). Antioxidant NAC inhibited p38MAPK activation by TNF-alpha. p38MAPK inhibitor SB203580 reduced the development of senescence and IL-6 by TNF-alpha and LPS. CSE treatment validated our current data. CONCLUSION: TNF-alpha caused OS-mediated p38MAPK induction, senescence, and IL-6 increase from AECs. LPS also induced senescence and IL-6 increase. Inflammatory and infectious factors may cause premature fetal cell senescence contributing to preterm birth pathophysiology. PMID- 29193449 TI - Characterization of glioblastoma in an orthotopic mouse model with magnetic resonance elastography. AB - Glioblastoma (GBM) is the most common primary brain tumor. It is highly malignant and has a correspondingly poor prognosis. Diagnosis and monitoring are mainly accomplished with MRI, but remain challenging in some cases. Therefore, complementary methods for tumor detection and characterization would be beneficial. Using magnetic resonance elastography (MRE), we performed a longitudinal study of the biomechanical properties of intracranially implanted GBM in mice and compared the results to histopathology. The biomechanical parameters of viscoelastic modulus, shear wave speed and phase angle were significantly lower in tumors compared with healthy brain tissue and decreased over time with tumor progression. Moreover, some MRE parameters revealed sub regions at later tumor stages, which were not easily detectable on anatomical MRI images. Comparison with histopathology showed that softer tumor regions contained necrosis and patches of viable tumor cells. In contrast, areas of densely packed tumor cells and blood vessels identified with histology coincided with higher values of viscoelastic modulus and shear wave speed. Interestingly, the phase angle was independent from these anatomical variations. In summary, MRE depicted longitudinal and morphological changes in GBM and may prove valuable for tumor characterization in patients. PMID- 29193450 TI - Clostridium butyricum exerts a neuroprotective effect in a mouse model of traumatic brain injury via the gut-brain axis. AB - BACKGROUND: Traumatic brain injury (TBI) is a common occurrence following gastrointestinal dysfunction. Recently, more and more attentions are being focused on gut microbiota in brain and behavior. Glucagon-like peptide-1 (GLP-1) is considered as a mediator that links the gut-brain axis. The aim of this study was to explore the neuroprotective effects of Clostridium butyricum (Cb) on brain damage in a mouse model of TBI. METHODS: Male C57BL/6 mice were subjected to a model of TBI-induced by weight-drop impact head injury and were treated intragastrically with Cb. The cognitive deficits, brain water content, neuronal death, and blood-brain barrier (BBB) permeability were evaluated. The expression of tight junction (TJ) proteins, Bcl-2, Bax, GLP-1 receptor (GLP-1R), and phosphorylation of Akt (p-Akt) in the brain were also measured. Moreover, the intestinal barrier permeability, the expression of TJ protein and GLP-1, and IL-6 level in the intestine were detected. RESULTS: Cb treatment significantly improved neurological dysfunction, brain edema, neurodegeneration, and BBB impairment. Meanwhile, Cb treatment also significantly increased the expression of TJ proteins (occludin and zonula occluden-1), p-Akt and Bcl-2, but decreased expression of Bax. Moreover, Cb treatment exhibited more prominent effects on decreasing the levels of plasma d-lactate and colonic IL-6, upregulating expression of Occludin, and protecting intestinal barrier integrity. Furthermore, Cb-treated mice showed increased the secretion of intestinal GLP-1 and upregulated expression of cerebral GLP-1R. CONCLUSIONS: Our findings demonstrated the neuroprotective effect of Cb in TBI mice and the involved mechanisms were partially attributed to the elevating GLP-1 secretion through the gut-brain axis. PMID- 29193448 TI - Increased CEST specificity for amide and fast-exchanging amine protons using exchange-dependent relaxation rate. AB - Chemical exchange saturation transfer (CEST) imaging of amides at 3.5 ppm and fast-exchanging amines at 3 ppm provides a unique means to enhance the sensitivity of detection of, for example, proteins/peptides and neurotransmitters, respectively, and hence can provide important information on molecular composition. However, despite the high sensitivity relative to conventional magnetic resonance spectroscopy (MRS), in practice, CEST often has relatively poor specificity. For example, CEST signals are typically influenced by several confounding effects, including direct water saturation (DS), semi solid non-specific magnetization transfer (MT), the influence of water relaxation times (T1w ) and nearby overlapping CEST signals. Although several editing techniques have been developed to increase the specificity by removing DS, semi solid MT and T1w influences, it is still challenging to remove overlapping CEST signals from different exchanging sites. For instance, the amide proton transfer (APT) signal could be contaminated by CEST effects from fast-exchanging amines at 3 ppm and intermediate-exchanging amines at 2 ppm. The current work applies an exchange-dependent relaxation rate (Rex ) to address this problem. Simulations demonstrate that: (1) slowly exchanging amides and fast-exchanging amines have distinct dependences on irradiation powers; and (2) Rex serves as a resonance frequency high-pass filter to selectively reduce CEST signals with resonance frequencies closer to water. These characteristics of Rex provide a means to isolate the APT signal from amines. In addition, previous studies have shown that CEST signals from fast-exchanging amines have no distinct features around their resonance frequencies. However, Rex gives Lorentzian lineshapes centered at their resonance frequencies for fast-exchanging amines and thus can significantly increase the specificity of CEST imaging for amides and fast-exchanging amines.

AB - OBJECTIVE: This study asked 40 cytotechnologists for their views on the competencies of newly graduated biomedical scientists in clinical cytology during the national conference of the Finnish Association of Cytotechnologists in November 2015. METHODS: The questionnaire mainly consisted of statements that were scored on a five-point Likert-scale, where 1 was not important and 5 was very important. It covered five sections of clinical cytology: sampling and techniques, gynaecological screening, non-gynaecological screening, safety and quality management, and miscellaneous. RESULTS: Of the 40 delegates approached to complete the questionnaire, 37 (92.5%) agreed. Respondents felt that important sampling and technique competencies were specimen fixation, with a mean score of 4.9 out of 5.0, types of specimens (4.7), Papanicolaou smear collection (4.7), Papanicolaou smear request information (4.7) and evaluation of specimen sufficiency (4.6). Less important competencies were examining FNAs (2.0) and nasopharyngeal specimens (2.2). The respondents had many expectations about how education in cytology could be developed, for example more theoretical lessons, more practice in microscope use, and consistent criteria for training and cooperation between cytology laboratories and universities of applied sciences. CONCLUSIONS: The cytotechnologists who took part in our survey expected newly graduated biomedical scientists to have basic competencies in cytology. These were sampling and techniques, laboratory safety and quality management, specimen adequacy and identifying normal cells taken during gynaecological screening. They were also keen to develop education in cytology.

AB - AIMS AND OBJECTIVES: To investigate the construct validity and reliability of the Chinese Comfort, Afford, Respect, and Expect scale, which can be used to determine clinical nurses' competence. The results can also serve to promote nursing competence and improve patient satisfaction. BACKGROUND: Nurse-patient interaction is critical for improving nursing care quality. However, to date, no relevant validated instrument has been proposed for assessing caring nurse patient interaction competence in clinical practice. This study adapted and validated the Chinese version of the caring nurse-patient interaction scale. DESIGN: A cross-cultural adaptation and validation study. METHODS: A psychometric analysis of the four major constructs of the Chinese Comfort, Afford, Respect, and Expect scale was conducted on a sample of 356 nurses from a medical centre in China. Item analysis and exploratory factor analysis were adopted to extract the main components, both the internal consistency and correlation coefficients were used to examine reliability and a confirmatory factor analysis was adopted to verify the construct validity. RESULTS: The goodness-of-fit results of the model were strong. The standardised factor loadings of the Chinese Comfort, Afford, Respect, and Expect scale ranged from 0.73-0.95, indicating that the validity and reliability of this instrument were favourable. Moreover, the 12 extracted items explained 95.9% of the measured content of the Chinese Comfort, Afford, Respect, and Expect scale. CONCLUSIONS: The results serve as empirical evidence regarding the validity and reliability of the Chinese Comfort, Afford, Respect, and Expect scale. RELEVANCE TO CLINICAL PRACTICE: Hospital nurses increasingly demand help from patients and their family members in identifying health problems and assisting with medical decision-making. Therefore, enhancing nurses' competence in nurse-patient interactions is crucial for nursing and hospital managers to improve nursing care quality. The Chinese caring nurse-patient interaction scale can serve as an effective tool for nursing and hospital managers to evaluate the caring nurse-patient interaction confidence of nurses and improve inpatient satisfaction and quality of care.

AB - In the retina, Muller glia have the potential to become progenitor cells with the ability to proliferate and regenerate neurons. However, the ability of Muller glia-derived progenitor cells (MGPCs) to proliferate and produce neurons is limited in higher vertebrates. Using the chick model system, we investigate how retinoic acid (RA)-signaling influences the proliferation and the formation of MGPCs. We observed an upregulation of cellular RA binding proteins (CRABP) in the Muller glia of damaged retinas where the formation of MGPCs is known to occur. Activation of RA-signaling was stimulated, whereas inhibition suppressed the proliferation of MGPCs in damaged retinas and in fibroblast growth factor 2 treated undamaged retinas. Furthermore, inhibition of RA-degradation stimulated the proliferation of MGPCs. Levels of Pax6, Klf4, and cFos were upregulated in MGPCs by RA agonists and downregulated in MGPCs by RA antagonists. Activation of RA-signaling following MGPC proliferation increased the percentage of progeny that differentiated as neurons. Similarly, the combination of RA and insulin-like growth factor 1 (IGF1) significantly increased neurogenesis from retinal progenitors in the circumferential marginal zone (CMZ). In summary, RA-signaling stimulates the formation of proliferating MGPCs and enhances the neurogenic potential of MGPCs and stem cells in the CMZ. Stem Cells 2018;36:392-405.

AB - In this study, pentraxin 3 (PTX3), C-reactive protein (CRP), and serum amyloid P component (SAP) concentrations in the amniotic fluid of women with preterm pre labor rupture of membranes (PPROM) were evaluated based on evidence of microbial invasion of the amniotic cavity (MIAC), intra-amniotic inflammation (IAI), and microbial-associated IAI. A total of 149 women with PPROM were included in this study. Amniotic fluid samples were obtained by transabdominal amniocentesis. Amniotic fluid PTX3, SAP, and CRP concentrations were assessed using enzyme linked immunosorbent assay. PTX3 and CRP concentrations were higher in women with MIAC, IAI, and microbial-associated IAI than in women without these conditions. SAP concentrations were only higher in the presence of IAI and microbial associated IAI. Amniotic fluid PTX3 concentrations of 11 ng/mL were found to be the best value for identifying the presence of microbial-associated IAI and IAI in women with PPROM. To conclude, amniotic fluid pentraxins are involved in intra amniotic inflammatory responses in pregnancies complicated by PPROM. PMID- 29193455 TI - The Parkinson's Disease Composite Scale: results of the first validation study. AB - BACKGROUND AND PURPOSE: The aim was to validate the Parkinson's Disease Composite Scale (PDCS). METHODS: The study included 194 Parkinson's disease (PD) patients in five countries. Investigators completed the following scales: PDCS, the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Parkinson's Disease Sleep Scale Version 2, Montreal Cognitive Assessment, the Scale for Evaluation of Neuropsychiatric Disorders in Parkinson's Disease and the Clinical Impression of Severity Index for PD (CISI-PD). For test-retest analysis, a second administration of the PDCS was carried out in 61 stable patients (as per the CISI-PD) in 7-14 days after the first evaluation. The PDCS is a novel scale for PD with a total of 17 items divided into four domains: motor, non-motor, treatment complications and disability. RESULTS: Parkinson's Disease Composite Scale mean and median values were close. Skewness values were into the criterion limits (-1 to +1). The complete range of scores was covered for 14 of the 17 items (83.4%). A floor effect of 25.26% and 28.25% was observed in the complications and disability level dimensions due to the proportion of patients free of these difficulties. No relevant floor or ceiling effect was observed for the PDCS total score (1.03% and 0.52%, respectively). The stability of the scale appeared excellent with most items meeting weighted kappa and intraclass correlation coefficient values >0.80. The convergent validity of the PDCS with corresponding scores of the MDS-UPDRS showed high correlation values (rS >= 0.60). The internal validity was into acceptable limits, with the majority of values higher than the minimal 0.30 threshold. The standard error of measurement suggested a satisfactory precision (SEM 3.81, <30% of the PDCS total score standard deviation). CONCLUSION: The PDCS appears to be a feasible, acceptable, reproducible and valid scale. PMID- 29193457 TI - Factors associated with adoption of coping strategies among Chinese patients with heart failure in ethnic minority regions. AB - AIMS AND OBJECTIVES: To examine the coping strategies in patients with heart failure (HF) in the ethnic minority regions of China and to explore the factors affecting the adoption of coping strategies. BACKGROUND: Effective coping with illness is an important element that influences the adaptation and increases the patient quality of life. Although different factors have been proposed to be determinants of coping strategy, findings are inconclusive, especially when it comes to the cultural background. DESIGN: A cross-sectional study was performed. METHODS: A total of 360 HF patients in four districts of Xinjiang were enrolled. All participants completed the Medical Coping Modes Questionnaire, the Minnesota Living with HF Questionnaire and self-management Questionnaire. RESULTS: Heart failure patients had lower scores in confrontation and higher scores in avoidance and acceptance resignation than patients in the Chinese norm. The multiple regression analysis revealed several factors that indicate confrontation coping including symptom management, employment status and psychological and social management, whereas religion (R2), disease duration, employment status and payment system (P2) were identified as indicators of avoidance coping. In addition, ethnicity (E1), disease duration and employment status were indicators of acceptance resignation coping. CONCLUSIONS: Our findings from this study suggest that HF patients in the ethnic minority regions may use less confrontation coping and more avoidance and acceptance resignation coping than patients in the Chinese norm. Moreover, the cultural background, duration of disease, quality of life and self-management play important roles in the selection of HF coping strategy. RELEVANCE TO CLINICAL PRACTICE: The disparities of racial/ethnic exist in coping strategy. Healthcare providers are required to better understand the role of religion in the coping process and how it contributes to the selection of coping strategies. PMID- 29193458 TI - High prevalence of Clostridium difficile on retail root vegetables, Western Australia. AB - AIMS: The incidence of community-associated Clostridium difficile infection (CA CDI) in Australia has increased since mid-2011. With reports of clinically important C. difficile strains being isolated from retail foods in Europe and North America, a foodborne source of C. difficile in cases of CA-CDI is a possibility. This study represents the first to investigate the prevalence and genotypes of C. difficile in Australian retail vegetables. METHODS AND RESULTS: A total of 300 root vegetables grown in Western Australia (WA) were collected from retail stores and farmers' markets. Three vegetables of the same kind bought from the same store/market were treated as one sample. Selective enrichment culture, toxin profiling and PCR ribotyping were performed. Clostridium difficile was isolated from 30% (30/100) of pooled vegetable samples, 55.6% of organic potatoes, 50% of nonorganic potatoes, 22.2% of organic beetroots, 5.6% of organic onions and 5.3% of organic carrots. Over half (51.2%, 22/43) the isolates were toxigenic. Many of the ribotypes of C. difficile isolated were common among human and Australian animals. CONCLUSIONS: Clostridium difficile could be found commonly on retail root vegetables of WA. This may be potential sources for CA CDI. SIGNIFICANCE AND IMPACT OF THE STUDY: This study enhances knowledge of possible sources of C. difficile in the Australian community, outside the hospital setting. PMID- 29193459 TI - Neuropeptide CART prevents memory loss attributed to withdrawal of nicotine following chronic treatment in mice. AB - Although chronic nicotine administration does not affect memory, its withdrawal causes massive cognitive deficits. The underlying mechanisms, however, have not been understood. We test the role of cocaine- and amphetamine-regulated transcript peptide (CART), a neuropeptide known for its procognitive properties, in this process. The mice on chronic nicotine treatment/withdrawal were subjected to novel object recognition task. The capability of the animal to discriminate between the novel and familiar objects was tested and represented as discrimination index (DI); reduction in the index suggested amnesia. Nicotine for 49 days had no effect on DI, but 8-hour withdrawal caused a significant reduction, followed by full recovery at 24-hour withdrawal timepoint. Bilateral CART infusion in dorsal hippocampus rescued deficits in DI at 8-hours, whereas CART-antibody infusion into the dorsal hippocampus attenuated the recovery at 24 hours. Commensurate changes were observed in the CART as well as CART mRNA profiles in the hippocampus. CART mRNA expression and the peptide immunoreactivity did not change significantly following chronic nicotine treatment. However, there was a significant reduction at 8-hour withdrawal, followed by a drastic increase in CART immunoreactivity as well as CART mRNA at 24-hour withdrawal, compared with 8-hour withdrawal. Distinct alpha7-nicotinic receptor immunoreactivity was detected on the hippocampal CART neurons, suggesting cholinergic inputs. An increase in the synaptophysin immunoreactive elements around CART cells in the dentate gyrus, cornu ammonis 3 and subiculum at 24-hour post-withdrawal timepoint suggested neuronal plasticity. CART circuit dynamics in the hippocampus seems to modulate short-term memory associated with nicotine withdrawal. PMID- 29193460 TI - Corticospinal tract diffusion properties and robotic visually guided reaching in children with hemiparetic cerebral palsy. AB - Perinatal stroke is the leading cause of hemiparetic cerebral palsy (CP), resulting in life-long disability. In this study, we examined the relationship between robotic upper extremity motor impairment and corticospinal tract (CST) diffusion properties. Thirty-three children with unilateral perinatal ischemic stroke (17 arterial, 16 venous) and hemiparesis were recruited from a population based research cohort. Bilateral CSTs were defined using diffusion tensor imaging (DTI) and four diffusion metrics were quantified: fractional anisotropy (FA), mean (MD), radial (RD), and axial (AD) diffusivities. Participants completed a visually guided reaching task using the KINARM robot to define 10 movement parameters including movement time and maximum speed. Twenty-six typically developing children underwent the same evaluations. Partial correlations assessed the relationship between robotic reaching and CST diffusion parameters. All diffusion properties of the lesioned CST differed from controls in the arterial group, whereas only FA was reduced in the venous group. Non-lesioned CST diffusion measures were similar between stroke groups and controls. Both stroke groups demonstrated impaired reaching performance. Multiple reaching parameters of the affected limb correlated with lesioned CST diffusion properties. Lower FA and higher MD were associated with greater movement time. Few correlations were observed between non-lesioned CST diffusion and unaffected limb function though FA was associated with reaction time (R = -0.39, p < .01). Diffusion properties of the lesioned CST are altered after perinatal stroke, the degree of which correlates with specific elements of visually guided reaching performance, suggesting specific relevance of CST structural connectivity to clinical motor function in hemiparetic children. PMID- 29193461 TI - Site-specific gene expression analysis from archived human intestine samples combining laser-capture microdissection and multiplexed color-coded probes. AB - BACKGROUND: Alterations of site-specific gene expression profiles in disease relevant networks within the different layers of the intestinal wall may contribute to the onset and clinical course of gastrointestinal disorders. To date, no systematic analysis has assessed and compared sub-regional gene expression patterns in all distinct layers of the gut using fresh frozen human samples. Our aim was to establish an optimized protocol for site-specific RNA isolation in order to achieve maximum RNA quality and amount for subsequent gene expression analysis combining laser-capture microdissection (LCM) with a probe based technology, the NanoString nCounter Analysis system. METHODS: Four full thickness colon samples from patients who underwent surgery due to pathological conditions were processed and separated into epithelium, lamina propria, myenteric plexus, submucosa, and tunica muscularis by LCM. Site-specific marker expression by nCounter technology was performed on total RNA from each sub region, respectively. KEY RESULTS: Collecting ~10 mm2 (~100 000-250 000 cells) of tissue from the epithelial layer, lamina propria, and myenteric plexus provided sufficient amounts of RNA of appropriate quality for subsequent analyses. In contrast, ~40 mm2 (~250 000-650 000 cells) of tissue were dissected from the less cell-rich submucosal and tunica muscularis layer. nCounter analysis revealed a site-specific expression pattern of marker genes in the different layers of the colonic wall which were highly correlating (r > .9). CONCLUSIONS AND INFERENCES: LCM in combination with nCounter expression analysis enables site-specific, sensitive, reliable detection, and quantification of mRNA from histologically heterogeneous tissues. PMID- 29193462 TI - Contribution of cardiac and extra-cardiac disease burden to risk of cardiovascular outcomes varies by ejection fraction in heart failure. AB - AIMS: Patients with heart failure (HF) often have multiple co-morbidities that contribute to the risk of adverse cardiovascular (CV) and non-CV outcomes. We assessed the relative contribution of cardiac and extra-cardiac disease burden and demographic factors to CV outcomes in HF patients with reduced (HFrEF) or preserved (HFpEF) left ventricular ejection fraction (LVEF). METHODS AND RESULTS: We utilized data from the CHARM trial, which enrolled HF patients across the ejection fraction spectrum. We decomposed the previously validated MAGGIC risk score into cardiac (LVEF, New York Heart Association class, systolic blood pressure, time since HF diagnosis, HF medication use), extra-cardiac (body mass index, creatinine, diabetes mellitus, chronic obstructive pulmonary disease, smoker), and demographic (age, gender) categories, and calculated subscores for each patient representing the burden of each component. Cox proportional hazards models were used to estimate the population attributable risk (PAR) associated with each component to the outcomes of death, CV death, HF, myocardial infarction, and stroke relative to patients with the lowest risk score. PARs for each component were depicted across the spectrum of LVEF. in 2675 chronic HF patients from North America [HFrEF (LVEF <=40%): n = 1589, HFpEF (LVEF >40%): n = 1086] with data available for calculation of the MAGGIC score, the highest risk of death and CV death was attributed to cardiac burden. This was especially evident in HFrEF patients (PAR: 76% cardiac disease vs. 58% extra-cardiac disease, P < 0.05). Conversely, in HFpEF patients, extra-cardiac burden accounted for a greater proportion of risk for death than cardiac burden (PAR: 15% cardiac disease vs. 49% extra-cardiac disease, P < 0.05). For HF hospitalization, the contribution of both cardiac and extra-cardiac burden was comparable in HFpEF patients (PAR: 42% cardiac disease vs. 53% extra-cardiac disease, P = NS). In addition, demographic burden was especially high in HFpEF patients, with 62% of deaths attributable to demographic characteristics. CONCLUSION: In North American HF patients enrolled in the CHARM trials, the relative contribution of cardiac and extra-cardiac disease burden to CV outcomes and death differed depending on LVEF. The high risk of events attributable to non-cardiac disease burden may help explain why cardiac disease-modifying medication proven to be efficacious in HFrEF patients has not proven beneficial in HFpEF. PMID- 29193466 TI - Asthma, urticaria and less rare than expected FPIES. PMID- 29193463 TI - Placental exosomes: A proxy to understand pregnancy complications. AB - Exosomes (30- to 150-nm particles), originating from multivesicular bodies by the invagination of the endosomal membrane, are communication channels between cells. Exosomes are released by various cell types and cargo proteins, lipids, and nucleic acids reflecting the physiologic status of their cells of origin and cause functional changes in recipient cells, which are likely dependent on their quantity and/or cargo contents. Recently, placental exosomes, produced by various placental cell types, have been isolated from maternal blood using the placental protein-specific marker, placental alkaline phosphatase (PLAP). PLAP-positive exosomes are seen in maternal blood as early as the first trimester of pregnancy and increase as gestation progresses, with maximum numbers seen at term. Although the functional relevance of placental exosomes is still under investigation, several studies have linked placental exosomes changes (quantity and cargo) reflecting placental dysfunctions associated with adverse pregnancy events. As placental exosomes can be isolated from maternal blood, they are liquid biopsies reflecting placental functions. Hence, they are useful as biomarkers of placental functions and dysfunctions obtainable through non-invasive approaches. This review summarizes the biogenesis, release, and functions of exosomes and specifically expounds the role of placental-specific exosomes and their significance associated with pregnancy complications. PMID- 29193464 TI - Functional connectivity in dementia with Lewy bodies: A within- and between network analysis. AB - Dementia with Lewy bodies (DLB) is a common form of dementia and is characterized by cognitive fluctuations, visual hallucinations, and Parkinsonism. The phenotypic expression of the disease may, in part, relate to alterations in functional connectivity within and between brain networks. This resting-state study sought to clarify this in DLB, how networks differed from Alzheimer's disease (AD), and whether they were related to clinical symptoms in DLB. Resting state networks were estimated using independent component analysis. We investigated functional connectivity changes in 31 DLB patients compared to 31 healthy controls and a disease comparator group of 29 AD patients using dual regression and FSLNets. Within-network connectivity was generally decreased in DLB compared to controls, mainly in motor, temporal, and frontal networks. Between-network connectivity was mainly intact; only the connection between a frontal and a temporal network showed increased connectivity in DLB. Differences between AD and DLB were subtle and we did not find any significant correlations with the severity of clinical symptoms in DLB. This study emphasizes the importance of reduced connectivity within motor, frontal, and temporal networks in DLB with relative sparing of the default mode network. The lack of significant correlations between connectivity measures and clinical scores indicates that the observed reduced connectivity within these networks might be related to the presence, but not to the severity of motor and cognitive impairment in DLB patients. Furthermore, our results suggest that AD and DLB may show more similarities than differences in patients with mild disease. PMID- 29193467 TI - Highly Selective Ruthenium-Catalyzed Direct Oxygenation of Amines to Amides. AB - Reports on aerobic oxidation of amines to amides are rare, and those reported suffer from several limitations like poor yield or selectivity and make use of pure oxygen under elevated pressure. Herein, we report a practical and an efficient ruthenium-catalyzed synthetic protocol that enables selective oxidation of a broad range of primary aliphatic, heterocyclic and benzylic amines to their corresponding amides, using readily available reagents and ambient air as the sole oxidant. Secondary amines instead, yield benzamides selectively as the sole product. Mechanistic investigations reveal intermediacy of nitriles, which undergo hydration to afford amide as the final product. PMID- 29193468 TI - Perceptions and experiences of nutritional care following the overwhelming experience of lower extremity amputation: A qualitative study. AB - INTRODUCTION: Good nutritional care of people following major lower extremity amputation is essential as poor nutritional status can lead to delayed wound healing. Working with patients to identify their perspectives on food, views on nutritional care and the need for dietary counselling enables the development of optimised nutritional care. AIMS AND OBJECTIVES: To explore hospital patients' perspectives on food, dietary counselling and their experiences of nutritional care following lower extremity amputation. DESIGN: A qualitative, explorative study design was employed. METHOD: An inductive content analysis of semi structured interviews with a purposive sample of 17 people over 50 years of age, who had recently undergone major lower extremity amputation, was undertaken. The study was reported according to the consolidated criteria for reporting qualitative research guideline. FINDINGS: Three themes emerged: responsible for own dietary intake, diet based on preferences and experiences with dietary counselling and feeling overwhelmed. The participants expressed motivation to ensure their nutritional needs were met but described feeling emotionally overwhelmed by the experience of amputation. They appeared not to expect nursing staff to focus on nutritional issues as they expressed belief that they themselves were solely responsible for their dietary intake. They described being motivated to receive nutritional counselling but indicated advice should be compatible with their lifestyle and eating habits. CONCLUSION: Lower extremity amputation can be an overwhelming experience which affects nutritional intake. People appear to consider themselves responsible for their nutritional care and describe not experiencing or expecting nursing staff to engage in this aspect of care. Dietary counselling by nurses who respect and incorporate patient preferences and experiences following amputation has the potential to enhance nutritional care. RELEVANCE TO CLINICAL PRACTICE: This study illustrates that nurses caring for people who undergo lower extremity amputation need to recognise that nutritional care is an essential component of nursing and should focus on working in partnership with the patient. PMID- 29193469 TI - Estimating the arterial input function from dynamic contrast-enhanced MRI data with compensation for flow enhancement (II): Applications in spine diagnostics and assessment of crohn's disease. AB - BACKGROUND: Pharmacokinetic (PK) models can describe microvascular density and integrity. An essential component of PK models is the arterial input function (AIF) representing the time-dependent concentration of contrast agent (CA) in the blood plasma supplied to a tissue. PURPOSE/HYPOTHESIS: To evaluate a novel method for subject-specific AIF estimation that takes inflow effects into account. STUDY TYPE: Retrospective study. SUBJECTS: Thirteen clinical patients referred for spine-related complaints; 21 patients from a study into luminal Crohn's disease with known Crohn's Disease Endoscopic Index of Severity (CDEIS). FIELD STRENGTH/SEQUENCE: Dynamic fast spoiled gradient echo (FSPGR) at 3T. ASSESSMENT: A population-averaged AIF, AIFs derived from distally placed regions of interest (ROIs), and the new AIF method were applied. Tofts' PK model parameters (including vp and Ktrans ) obtained with the three AIFs were compared. In the Crohn's patients Ktrans was correlated to CDEIS. STATISTICAL TESTS: The median values of the PK model parameters from the three methods were compared using a Mann-Whitney U-test. The associated variances were statistically assessed by the Brown-Forsythe test. Spearman's rank correlation coefficient was computed to test the correlation of Ktrans to CDEIS. RESULTS: The median vp was significantly larger when using the distal ROI approach, compared to the two other methods (P < 0.05 for both comparisons, in both applications). Also, the variances in vp were significantly larger with the ROI approach (P < 0.05 for all comparisons). In the Crohn's disease study, the estimated Ktrans parameter correlated better with the CDEIS (r = 0.733, P < 0.001) when the proposed AIF was used, compared to AIFs from the distal ROI method (r = 0.429, P = 0.067) or the population-averaged AIF (r = 0.567, P = 0.011). DATA CONCLUSION: The proposed method yielded realistic PK model parameters and improved the correlation of the Ktrans parameter with CDEIS, compared to existing approaches.

PMID- 29193471 TI - Effect of quantitative assessment-based nursing intervention on the bowel function and life quality of patients with neurogenic bowel dysfunction after spinal cord injury. AB - AIMS AND OBJECTIVES: To study the effect of quantitative assessment-based nursing intervention on the bowel function and life quality of patients with neurogenic bowel dysfunction after spinal cord injury. BACKGROUND: Neurogenic bowel dysfunction after spinal cord injury was clinically manifested by abdominal distension, intractable constipation, prolonged defecation and faecal incontinence, which seriously affected the normal life of patients. Traditional ways of nursing for these patients focused on basic care, but lacked sufficient recognition of disease severity and individual needs. DESIGN: One hundred and eighty-four patients with neurogenic bowel dysfunction after spinal cord injury were randomly allocated into observation group (n = 92) and control group (n = 92). METHODS: The patients in the control group were given regular nursing, and the patients in the observation group were given quantitative assessment-based nursing intervention. Recovery of bowel function, quality of life and satisfaction were compared between the two groups. RESULTS: Scores for bowel function including bloating, constipation, prolonged defecation, defecation drug dependence and faecal incontinence in the observation group were significantly lower than those in the control group (p < .05). The scores for the quality of life including physical function, general health, social functioning, role motional, mental health in the observation group were significantly higher than those in the control group (p < .001). Finally, the satisfaction rate in the observation group was 95.56%, which was significantly higher than that in the control group (83.7%) (p < .01). CONCLUSION: We concluded that quantitative assessment-based nursing intervention contributed to recovery of bowel function and improvement of life quality and satisfaction. RELEVANCE TO CLINICAL PRACTICE: Our finding can increase the rational allocation of nurse-patient ratio and provide personalised nursing for severe patients to reduce complications and promote the rehabilitation of the disease. Our findings can also serve as a reference for other countries to develop the nurse practitioner role. PMID- 29193472 TI - Intellectual disability is a risk factor for delayed emergence from total intravenous anaesthesia. AB - BACKGROUND: Previous studies have suggested that ID influences the depth of general anaesthesia (GA) and delays emergence from GA. In this retrospective cohort study, we investigated whether ID affects the time taken to emerge from GA. METHODS: We selected dental patients who underwent GA at the Department of Dental Anaesthesiology, Okayama University Hospital, using predefined inclusion and exclusion criteria, before dividing the selected participants into ID and non ID (control) groups. Relevant data were collected from electronic anaesthesia records. Emergence time, the time from the discontinuation of propofol and remifentanil to tracheal extubation, was recorded for each patient. We compared the data of the ID group and control group. The association between ID and the emergence time was tested for statistical significance. Multivariate linear regression analysis was used to control for confounders. RESULTS: A total of 97 cases (control = 50, ID = 47) were included in the study. The emergence time was significantly longer in the ID group (ID group: 15.8 +/- 6.6 min, control group: 10.8 +/- 3.6 min). The ID group included more men and lower propofol and remifentanil infusion rates. The treatment time was longer, and the mean bispectral index was lower in the ID group. Sevoflurane inhalation was used only for anaesthesia induction in the ID group. In the multivariate linear regression analysis, ID was found to be significantly associated with a longer emergence time. CONCLUSION: Our results suggest that ID is associated with a longer emergence time from GA. PMID- 29193473 TI - Autoimmune glial fibrillary acidic protein astrocytopathy in Chinese patients: a retrospective study. AB - BACKGROUND AND PURPOSE: The aim was to describe the clinical, radiological and pathological features of an autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy. METHODS: Data from 19 patients with positive GFAP-immunoglobulin G in cerebrospinal fluid (CSF) were retrospectively analyzed. RESULTS: The main disease manifestations included myelitis (68.4%), headache (63.2%), abnormal vision (63.2%), fever (52.6%), ataxia (36.8%), psychosis (31.6%), dyskinesia (15.8%), dementia (15.8%) and seizure (10.5%). Seventeen patients had brain abnormalities (89.5%), of which eight (42.1%) revealed the characteristic radial enhancing and laminar patterns. Cortical abnormalities were found in four patients (21.1%). Other abnormalities were found in the hypothalamus, midbrain, pons, medulla cerebellum, meninges and skull. Eleven patients had longitudinally extensive spinal cord lesions. CSF abnormalities were detected in all patients. Pathological examinations of four patients revealed extensive inflammation, with prominent perivascular B cells and T cells. Abundant antibody-secreting cells were noted in the interstitial and perivascular spaces. Immunohistochemical analysis showed loss of astrocytes and neurons. CONCLUSION: The present patients with positive GFAP-immunoglobulin G are highly similar to autoimmune GFAP astrocytopathy, described in a recent report. The features of the neuropathology and immunopathology of GFAP astrocytopathies were perivascular inflammation and loss of astrocytes and neurons. PMID- 29193474 TI - Copper(0) Mediated Single Electron Transfer Controlled Radical Polymerization toward C?F Bonds on Poly(vinylidene fluoride). AB - The first copper(0) mediated controlled radical polymerization (CRP) of methyl methacrylate (MMA) toward C?F bonds onto poly(vinylidene fluoride) (PVDF) is reported with rather high activity. By avoiding the halogen exchange, Cu0 instead of CuI complexes utilized as catalyst is responsible for the significantly improved polymerization activity. Using F?H decoupled nuclear magnetic resonance technique, the grafting sites onto PVDF are finely located. From this, detailed topologic information including the grafting density, average length of each side chain, along with the overall grafted content of PMMA, is detected by tracking the polymerization as a function of time. This work offers not only a facile CRP strategy based on inactive C?F bonds but also a deep insight into the cleavage of F-bearing compounds in organic chemistry.

PMID- 29193476 TI - Mere social knowledge impacts children's consumption and categorization of foods. AB - How does social information affect the perception of taste early in life? Does mere knowledge of other people's food preferences impact children's own experience when eating? In Experiment 1, 5- and 6-year-old children consumed more of a food described as popular with other children than a food that was described as unpopular with other children, even though the two foods were identical. In Experiment 2, children ate more of a food described as popular with children than a food described as popular with adults. Experiment 3 tested whether different perceptual experiences of otherwise identical foods contributed to the mechanisms underlying children's consumption. After sampling both endpoints of a sweet-to sour range (applesauce with 0 mL or 5mL of lemon juice added), children were asked to taste and categorize applesauce samples with varying amounts of lemon juice added. When classifying ambiguous samples that were near the midpoint of the range (2 mL and 3 mL), children were more likely to categorize popular foods as sweet as compared to unpopular foods. Together, these findings provide evidence that social information plays a powerful role in guiding children's consumption and perception of foods. Broader links to the sociality of food selection are discussed. PMID- 29193477 TI - Outcomes of endoscopic ultrasound-guided pancreatic FNAC diagnosis for solid and cystic lesions at Manchester Royal Infirmary based upon the Papanicolaou Society of Cytopathology pancreaticobiliary terminology classification scheme. AB - OBJECTIVE: To compare endoscopic ultrasound (EUS)-FNAC diagnosis of pancreatic lesions with patient outcome based upon the Papanicolaou Society of Cytopathology pancreaticobiliary terminology classification scheme diagnostic categories: Panc 1 (non-diagnostic); Panc 2 (negative for malignancy/neoplasia); Panc 3 (atypical); Panc 4B (neoplastic, benign); Panc 4O (neoplastic, other); Panc 5 (suspicious of malignancy); and Panc 6 (positive/malignant). METHODS: All EUS-FNA pancreas specimens taken at Manchester Royal Infirmary in 2015 were prospectively classified according to the above scheme at the time of cytology reporting and data recorded prospectively. Subsequently, outcomes based on clinical follow-up or histopathology diagnosis were compared with the cytology diagnosis. RESULTS: 120 EUS-FNA pancreas specimens from 111 patients were received, of which 112 (93.3%) specimens had follow-up data. There were 79 and 41 EUS-FNA pancreas specimens from solid and cystic lesions, respectively. Based on the cytology diagnosis the specimens were classified as Panc 1 (7.5%), Panc 2 (33.3%), Panc 3 (2.5%), Panc 4B (2.5%), Panc 4O (15.0%), Panc 5 (3.3%) and Panc 6 (35.9%). The performance indicators for diagnosis of malignancy or neoplasia with malignant potential, included sensitivity (95.4%), specificity (100%), positive predictive value (100%), negative predictive value (92.3%), false positive rate (0%) and false negative rate (4.6%). CONCLUSIONS: The Papanicolaou Society of Cytopathology pancreaticobiliary terminology classification scheme is a logical system that can easily be introduced in a diagnostic cytopathology service. This classification scheme acts as an aid to diagnostic reporting, clear communication of significant results including risk of neoplasia/malignancy to clinicians, clinical audit and comparison of results with other centres.

AB - The relaxant effects of carvacrol, a phenolic monoterpene, on tracheal smooth muscle and its preventive effect on asthmatic animals were reported. The effect of carvacrol in asthmatic patients was examined in the placebo group (Group P, n = 11) receiving placebo and treatment group (Group C, n = 12), which received carvacrol capsule (1.2 mg/kg/day) for 2 months in a double-blind manner. Pulmonary function tests, respiratory symptoms, hematological indices, and high sensitivity C-reactive protein (hs-CRP) were measured before, 1 and 2 months after starting treatment. At the end of treatment period, Pulmonary function tests values in Group C were significantly increased (p < .05 to p < .001). Most respiratory symptoms were also significantly reduced in Group C at the end of 2 month treatment (p < .05 to p < .001). Total and differential white blood cell (p < .05 to p < .001), as well as serum levels of hs-CRP in Group C were also significantly reduced after 2-month treatment with carvacrol (p < .001). Mean corpuscular hemoglobin concentration and hematocrit were changed in Group C (p < .05 and p < .01, respectively). However, in Group P, there was no significant changes in the evaluated parameters. Pulmonary function tests were increased but respiratory symptoms, inflammatory cells, and hs-CRP were reduced in asthmatic patients who received carvacrol that indicates its therapeutic effect on asthma. PMID- 29193479 TI - BCL-XL binds and antagonizes RASSF6 tumor suppressor to suppress p53 expression. AB - RASSF6, a member of the tumor suppressor Ras-association domain family proteins, induces apoptosis in the caspase-dependent and caspase-independent manners. RASSF6 interacts with MDM2 and stabilizes p53. BCL-XL is a prosurvival member of BCL-2 family proteins. BCL-XL directly inhibits proapoptotic BAX and BAK. BCL-XL also traps tBID, a proapoptotic activator BH3-only protein, and sequesters p53. In addition, BCL-XL regulates the mitochondrial membrane permeability via voltage dependent anion channel. In these manners, BCL-XL plays an antiapoptotic role. We report the interaction of BCL-XL with RASSF6. BCL-XL inhibits the interaction between RASSF6 and MDM2 and suppresses p53 expression. Consequently, BCL-XL antagonizes RASSF6-mediated apoptosis. Thus, the inhibition of RASSF6-mediated apoptosis also underlies the prosurvival role of BCL-XL. PMID- 29193480 TI - Rhabdomyolysis and fluctuating asymptomatic hyperCKemia associated with CACNA1S variant. AB - BACKGROUND AND PURPOSE: CACNA1S encodes Cav 1.1, a voltage sensor for muscle excitation-contraction coupling, which activates the ryanodine receptor 1 (RYR1) leading to calcium release from the sarcoplasmic reticulum. CACNA1S mutations cause hypokalemic periodic paralysis, malignant hyperthermia and congenital myopathy. RYR1 mutations result in congenital myopathy, malignant hyperthermia and rhabdomyolysis. METHODS: The aim was to describe a novel phenotype associated with a CACNA1S variant at a site previously linked to hypokalemic periodic paralysis. RESULTS: The patient presented with fluctuating asymptomatic creatine kinase elevation after an episode of rhabdomyolysis but has no history of periodic paralysis. His muscle biopsy showed core-like structures occurring mainly in type 2 fibers. He carries a novel Cav 1.1 variant (p.Arg528Leu) affecting a highly conserved amino acid. Different mutations at the same location cause hypokalemic periodic paralysis. CONCLUSION: This case underscores the similarity between the phenotypes caused by mutations in two functionally linked proteins, RYR1 and Cav 1.1.

AB - AIMS AND OBJECTIVES: To investigate the feasibility of a 13-week mentoring programme in providing social support to promote hope for recovery in anorexia nervosa. BACKGROUND: With no clear first-line psychological treatment for people with anorexia nervosa, mentoring support programmes, as an adjunct to treatment, may provide the social support necessary to promote hope for recovery. DESIGN: A mixed-method study; participatory action research. METHODS: Women (n = 11), recovering and who had recovered from anorexia nervosa, participated in the programme and completed self-report questionnaires related to quality of life, distress and the mentoring relationship at different time points. Qualitative feedback from logbooks, workshop evaluation questionnaires, interviews and focus groups was also collected to assess the programme's acceptability. RESULTS: General compliance for completing most study outcome questionnaires was 90%; however, the mentoring relationship questionnaires were not completed to the same degree. Five key themes emerged from the focus group/interview data: (i) she understands me and could relate to me; (ii) reconnecting with the world-asking questions and being challenged; (iii) mentors' altruistic motivations and the transformation and discovery of self; (iv) instilling hope-recovery is possible; and (v) effective communication-the key to successful mentoring. CONCLUSIONS: Further research is needed; however, the results provide preliminary support for the mentoring programme's feasibility as an adjunct to treatment. We found that having someone who understands, to talk and share with, met a clear need for people with anorexia nervosa. RELEVANCE TO CLINICAL PRACTICE: While further research is warranted mentoring support or recovered mentors, may play a potentially valuable role in supporting those in community settings.

PMID- 29193483 TI - Isomerization of Allylic Alcohols to Ketones Catalyzed by Well-Defined Iron PNP Pincer Catalysts. AB - [Fe(PNP)(CO)HCl] (PNP=di-(2-diisopropylphosphanyl-ethyl)amine), activated in situ with KOtBu, is a highly active catalyst for the isomerization of allylic alcohols to ketones without an external hydrogen supply. High reaction rates were obtained at 80 degrees C, but the catalyst is also sufficiently active at room temperature with most substrates. The reaction follows a self-hydrogen-borrowing mechanism, as verified by DFT calculations. An alternative isomerization through alkene insertion and beta-hydride elimination could be excluded on the basis of a much higher barrier. In alcoholic solvents, the ketone product is further reduced to the saturated alcohol. PMID- 29193485 TI - Roland Hauspie (April 8, 1948-April 25, 2017). PMID- 29193486 TI - Characterization of Ras k 1 a novel major allergen in Indian mackerel and identification of parvalbumin as the major fish allergen in 33 Asia-Pacific fish species. AB - BACKGROUND: Fish is a well-recognized cause of food allergy and anaphylaxis. The evolutionary and taxonomic diversity of the various consumed fish species pose a challenge in the identification and characterization of the major fish allergens critical for reliable diagnostics. Globally, fish is a rising cause of food allergy complicated by a large under-investigated variety of species as well as increasing global tourism and trade. This is the first comprehensive study on allergen profiles of heat-processed fish from Vietnam. OBJECTIVE: The aim of this study was to identify the major heat-stable allergens from frequently exported Asia-Pacific freshwater and marine fish and to characterize the major allergen parvalbumin (PV) from one of the most consumed and exported fish species from Asia, the Indian mackerel (Rastrelliger kanagurta). METHODS: Heated protein extracts from 33 fish species were separated by gel electrophoresis. PV isoforms were identified by immunoblotting utilizing 3 different PV-specific monoclonal and polyclonal antibodies and further characterized by mass spectrometry. IgE reactivity was investigated using sera from 21 patients with confirmed fish allergy. RESULTS: Heat-stable IgE-reactive PVs, with up to 5 isoforms per species, were identified in all 33 analysed fish species. In the Indian mackerel, 7 PV isoforms were identified by 2D-gel electrophoresis combined with mass spectrometric analyses. The amino acid sequence deduced from cDNA of the most expressed isoform showed a high identity (>90%) to PVs from 2 other mackerel species. CONCLUSIONS AND CLINICAL RELEVANCE: Different PVs were identified as the major heat-stable allergens in all 33 analysed freshwater and marine fish species from Vietnam, many of which are exported world-wide and 21 species that have never been investigated before. The Indian mackerel PV represents a novel fish allergen, now officially registered as Ras k 1. Improved diagnostics for fish allergy against Asia-Pacific species should be developed with focus on PV. PMID- 29193484 TI - Network dynamics engaged in the modulation of motor behavior in stroke patients. AB - Stroke patients with motor deficits typically feature enhanced neural activity in several cortical areas when moving their affected hand. However, also healthy subjects may show higher levels of neural activity in tasks with higher motor demands. Therefore, the question arises to what extent stroke-related overactivity reflects performance-level-associated recruitment of neural resources rather than stroke-induced neural reorganization. We here investigated which areas in the lesioned brain enable the flexible adaption to varying motor demands compared to healthy subjects. Accordingly, eleven well-recovered left hemispheric chronic stroke patients were scanned using functional magnetic resonance imaging. Motor system activity was assessed for fist closures at increasing movement frequencies performed with the affected/right or unaffected/left hand. In patients, an increasing movement rate of the affected hand was associated with stronger neural activity in ipsilesional/left primary motor cortex (M1) but unlike in healthy controls also in contralesional/right dorsolateral premotor cortex (PMd) and contralesional/right superior parietal lobule (SPL). Connectivity analyses using dynamic causal modeling revealed stronger coupling of right SPL onto affected/left M1 in patients but not in controls when moving the affected/right hand independent of the movement speed. Furthermore, coupling of right SPL was positively coupled with the "active" ipsilesional/left M1 when stroke patients moved their affected/right hand with increasing movement frequency. In summary, these findings are compatible with a supportive role of right SPL with respect to motor function of the paretic hand in the reorganized brain. PMID- 29193487 TI - Impaired fasting glucose and the metabolic profile in Danish children and adolescents with normal weight, overweight, or obesity. AB - OBJECTIVE: Whether the definitions of impaired fasting glucose (IFG) from the American Diabetes Association (ADA) and the World Health Organization (WHO) differentially impact estimates of the metabolic profile and IFG-related comorbidities in Danish children and adolescents is unknown. METHODS: Two thousand one hundred and fifty four (979 boys) children and adolescents with overweight or obesity (median age 12 years) and 1824 (728 boys) children with normal weight (median age 12 years) from The Danish Childhood Obesity Biobank were studied. Anthropometrics, blood pressure, puberty, and fasting concentrations of glucose, insulin, glycosylated hemoglobin (HbA1c), and lipids were measured. RESULTS: About 14.1% of participants with overweight or obesity exhibited IFG according to the ADA and 3.5% according to the WHO definition. Among individuals with normal weight, the corresponding prevalences were 4.3% and 0.3%. IFG was associated with a higher systolic blood pressure, higher concentrations of HbA1c, insulin, C-peptide (P < .0001) and triglycerides (P = .03), and lower HOMA2-IS and HOMA2-B (P < .0001) independent of sex, age, puberty, waist-to-height ratio, and degree of obesity. Furthermore, IFG was associated with a higher risk for hypertension (OR = 1.66 [95%CI: 1.21; 2.28], P = .002) and dyslipidemia (OR = 1.90 [95%CI: 1.38; 2.56], P < .0001) compared with the group without IFG independent of age, sex, and puberty. CONCLUSIONS: The prevalence of IFG, when applying the ADA criterion compared with the WHO criterion, was 4 times higher in individuals with overweight and obesity and 14 times higher in individuals with normal weight in this study sample of children and adolescents. IFG was associated with a higher risk of hypertension and dyslipidemia compared with their normoglycemic peers regardless of the definition applied.

PMID- 29193490 TI - The Eastern side of the Westernmost Europeans: Insights from subclades within Y chromosome haplogroup J-M304. AB - OBJECTIVES: We examined internal lineages and haplotype diversity in Portuguese samples belonging to J-M304 to improve the spatial and temporal understanding of the introduction of this haplogroup in Iberia, using the available knowledge about the phylogeography of its main branches, J1-M267 and J2-M172. METHODS: A total of 110 males of Portuguese descent were analyzed for 17 Y-chromosome bi allelic markers and seven Y-chromosome short tandem repeats (Y-STR) loci. RESULTS: Among J1-M267 individuals (n = 36), five different sub-haplogroups were identified, with the most common being J1a2b2-L147.1 (~72%), which encompassed the majority of representatives of the J1a2b-P58 subclade. One sample belonged to the rare J1a1-M365.1 lineage and presented a core Y-STR haplotype consistent with the Iberian settlement during the fifth century by the Alans, a people of Iranian heritage. The analysis of J2-M172 Portuguese males (n = 74) enabled the detection of the two main subclades at very dissimilar frequencies, J2a-M410 (~80%) and J2b M12 (~20%), among which the most common branches were J2a1(xJ2a1b,h)-L26 (22.9%), J2a1b(xJ2a1b1)-M67 (20.3%), J2a1h-L24 (27%), and J2b2-M241 (20.3%). CONCLUSIONS: While previous inferences based on modern haplogroup J Y-chromosomes implicated a main Neolithic dissemination, here we propose a later arrival of J lineages into Iberia using a combination of novel Portuguese Y-chromosomal data and recent evidence from ancient DNA. Our analysis suggests that a substantial tranche of J1 M267 lineages was likely carried into the Iberian Peninsula as a consequence of the trans-Mediterranean contacts during the first millennium BC, while most of the J2-M172 lineages may be associated with post-Neolithic population movements within Europe. PMID- 29193491 TI - Age-related changes in the dynamics of fear-related regulation in early childhood. AB - Self-regulation is a dynamic process wherein executive processes (EP) delay, minimize or desist prepotent responses (PR) that arise in situations that threaten well-being. It is generally assumed that, over the course of early childhood, children expand and more effectively deploy their repertoire of EP related strategies to regulate PR. However, longitudinal tests of these assumptions are scarce in part because self-regulation has been mostly studied as a static construct. This study engages dynamic systems modeling to examine developmental changes in self-regulation between ages 2 and 5 years. Second-by second time-series data derived from behavioral observations of 112 children (63 boys) faced with novel laboratory-based situations designed to elicit wariness, hesitation, and fear were modeled using differential equation models designed to capture age-related changes in the intrinsic dynamics and bidirectional coupling of PR (fear/wariness) and EP (strategy use). Results revealed that dynamic models allow for the conceptualization and measurement of fear regulation as intrinsic processes as well as direct and indirect coupling between PR and EP. Several patterns of age-related changes were in line with developmental theory suggesting that PR weakened and was regulated more quickly and efficiently by EP at age 5 than at age 2. However, most findings were in the intrinsic dynamics and moderating influences between PR and EP rather than direct influences. The findings illustrate the precision with which specific aspects of self-regulation can be articulated using dynamic systems models, and how such models can be used to describe the development of self-regulation in nuanced and theoretically meaningful ways. PMID- 29193492 TI - Perfusion measures for symptom severity and differential outcome of revascularization in limb ischemia: Preliminary results with arterial spin labeling reactive hyperemia. AB - BACKGROUND: Previously, a theoretical model based on microvascular physiology was established to facilitate the interpretation of calf perfusion dynamics recorded by arterial spin labeling (ASL). PURPOSE: To investigate the clinical relevance of novel perfusion indices by comparing them to the symptoms, response to revascularization, and short-term functional outcome in patients with peripheral arterial disease (PAD). STUDY TYPE: Prospective cohort study. POPULATION: Nineteen patients with PAD. FIELD STRENGTH/SEQUENCE: Pulsed ASL at 3T. ASSESSMENT: The mid-calf reactive hyperemia induced by 2 minutes of arterial occlusion was recorded in PAD patients. The perfusion responses were characterized by the peak, time-to-peak, and physiological model-derived indices including the baseline perfusion fr , arterial resistance Ra , and compliance Ca , and sensitivity gATP and response time tauATP of downstream microvasculature to metabolic stress. These indices were compared to the disease severity and outcome within 6 months after revascularization assessed by self-reported symptoms and the ankle-brachial index. Disease severity was categorized as asymptomatic, claudication, or critical limb ischemia. The outcome was categorized as symptom resolved or limited improvement. STATISTICAL TESTS: Severity and outcome groups were compared using Mann-Whitney and Kruskal-Wallis tests with Holm-Sidak adjustments. RESULTS: The peak perfusion decreased and model arterial resistance increased progressively with increasing severity of limb ischemia (P = 0.0402 and 0.0413, respectively). Eleven patients had a successful endovascular procedure, including six patients who had symptoms resolved, four patients who had remaining leg pain, and one patient lost to follow-up. The subjects with limited improvement had significantly lower preintervention microvascular sensitivity gATP than those with symptoms resolved (8.72 +/- 1.46 vs. 4.93 +/- 0.91, P = 0.0466). DATA CONCLUSION: ASL reactive hyperemia reflects multiple aspects of the pathophysiology. Measures of macrovascular arterial disease are related to the manifested symptom severity, whereas preintervention gATP associated with microvascular dysfunction is related to prognosis following revascularization.

PMID- 29193493 TI - The Sleep Condition Indicator: reference values derived from a sample of 200 000 adults. AB - The Sleep Condition Indicator (SCI) is an eight-item rating scale that was developed to screen for insomnia disorder based on DSM-5 criteria. It has been shown previously to have good psychometric properties among several language translations. We developed age- and sex-referenced values for the SCI to assist the evaluation of insomnia in everyday clinical practice. A random sample of 200 000 individuals (58% women, mean age: 31 +/- 13 years) was selected from those who had completed the SCI via several internet platforms. Descriptive and inferential methods were applied to generate reference data and indices of reliable change for the SCI for men and women across the age deciles 16-25, 26 35, 36-45, 46-55, 56-65 and 66-75 years. The mean SCI score for the full sample was 14.97 +/- 5.93. Overall, women scored worse than men (14.29 +/- 5.83 versus 15.90 +/- 5.94; mean difference: -1.60, eta2 = 0.018, Cohen's d = 0.272) and those of older age scored worse than those younger (-0.057 points per year, 95% confidence interval (CI): -0.059 to -0.055) relative to age 16-25 years. The Reliable Change Index was established at seven scale points. In conclusion, the SCI is a useful instrument for clinicians and researchers that can help them to screen for insomnia, compare completers to individuals of similar age and sex and establish whether a reliable change was achieved following treatment. PMID- 29193494 TI - "It's good, they're like me; the same but different." An interpretative phenomenological analysis of the identities of women with down's syndrome. AB - BACKGROUND: For people with disabilities, identity formation is based on responses to hierarchical values determined by able populations. Some adopt a disability identity, whereas others may seek to conceal their disability. No research has focused on how women with Down's Syndrome form an identity. DESIGN: Eight women with Down's Syndrome took part in semi-structured interviews designed to find out more about their individual and shared identities. The transcripts were analysed using interpretive phenomenological analysis. FINDINGS: Negative assumptions of others and oppressive, paternalistic care often lead to a lack of ownership over narratives. "Finding a place in society" is an attempt to challenge this and gain a sense of ownership over their lives. CONCLUSIONS: This research uncovered the individual and shared identities that women with Down's Syndrome construct. Services need to be aware of the role they have in supporting these women to develop autonomy and ownership over their lives. PMID- 29193495 TI - Premature birth affects the degree of airway dysanapsis and mechanical ventilatory constraints. AB - NEW FINDINGS: What is the central question of this study? Adult survivors of preterm birth without (PRE) and with bronchopulmonary dysplasia (BPD) have airflow obstruction at rest and significant mechanical ventilatory constraints during exercise compared with those born at full term (CON). Do PRE/BPD have smaller airways, indexed via the dysanapsis ratio, than CON? What is the main finding and its importance? The dysanapsis ratio was significantly smaller in BPD and PRE compared with CON, with BPD having the smallest dysanapsis ratio. These data suggest that airflow obstruction in PRE and BPD might be because of smaller airways than CON. Adult survivors of very preterm birth (<=32 weeks gestational age) without (PRE) and with bronchopulmonary dysplasia (BPD) have obstructive lung disease as evidenced by reduced expiratory airflow at rest and have significant mechanical ventilatory constraints during exercise. Airflow obstruction, in any conditions, could be attributable to several factors, including small airways. PRE and/or BPD could have smaller airways than their counterparts born at full term (CON) owing to a greater degree of dysanaptic airway development during the pre- and/or postnatal period. Thus, the purpose of the present study was to compare the dysanapsis ratio (DR), as an index of airway size, between PRE, BPD and CON. To do so, we calculated DR in PRE (n = 21), BPD (n = 14) and CON (n = 34) individuals and examined flow-volume loops at rest and during submaximal exercise. The DR, using multiple estimates of static recoil pressure, was significantly smaller in PRE and BPD (0.16 +/- 0.05 and 0.10 +/- 0.03 a.u.) compared with CON (0.22 +/- 0.04 a.u.; both P < 0.001) and smallest in BPD (P < 0.001). The DR was significantly correlated with peak expiratory airflow at rest (r = 0.42; P < 0.001) and the extent of expiratory flow limitation during exercise (r = 0.60; P < 0.001). Our findings suggest that PRE/BPD might have anatomically smaller airways than CON, which might help to explain their lower expiratory airflow rate at rest and during exercise and further our understanding of the consequences of preterm birth and neonatal O2 therapy.

PMID- 29193498 TI - The impact of shift work on intensive care nurses' lives outside work: A cross sectional study. AB - AIMS AND OBJECTIVES: To examine how shift work affects intensive care nurses' lives outside work. BACKGROUND: Shift work is unavoidable for many nurses. When attempting to minimise negative effects of shift work, it is important to identify areas which affect nurses working shifts. DESIGN: A cross-sectional study. METHODS: A questionnaire survey among Danish intensive care nurses concerning experiences with shift work and family life, spare time activities, sleep and health. RESULTS: A total of 114 nurses (88%) participated. Shift work was found to influence the opportunities for spare time activities, and about 25% of both evening- and night-shift groups found that working shifts sometimes led to social isolation. A total of 58% of nurses working evening shifts sometimes to very often experienced having trouble falling asleep when working shifts. Night shift workers had a higher percentage of physical and mental symptoms when working shifts compared with evening-shift workers, with mood swings and headaches being the most common. The median score for thriving on working shifts was 8 (IQR 5-9) for evening-shift workers and 8 (IQR 7-9) for night-shift workers (scale 0-10 with 10 being the highest level of thriving). CONCLUSION: Shift workers reported that working shifts had a negative impact on life outside work. Opportunities for participating in spare time activities and difficulties falling asleep after shifts were the main issues for evening-shift workers, whereas physical symptoms such as headaches and mood swings were more dominant among night-shift workers. Despite the negative effects, the participants generally thrived on working shifts. RELEVANCE TO CLINICAL PRACTICE: By identifying modifiable areas which negatively influence life outside work when working shifts, it will be possible subsequently to plan interventions aimed at decreasing the negative effects. Interventions may include nurses having increased influence on their work schedules and education in sleep hygiene and dietary habits.

AB - BACKGROUND AND PURPOSE: In the era of neurological subspecialization, most neurologists will have a field of specialist interest. The aim of this cross sectional multinational study was to identify the key areas of interest among trainees or junior specialists, assess the potential influence of an interest in research and consider the results in light of population needs. METHODS: A total of 300 residents and junior neurologists who received a bursary to attend the European Academy of Neurology conference were invited to participate in this study. Demographic and work-related characteristics, as well as main subspecialty of choice, were examined via an anonymous electronic questionnaire. Participants holding a higher degree (PhD/MD) or working in research posts were considered research oriented. RESULTS: In total, 191 neurologists in training or junior specialists responded (response rate 63.7%). Full data were available for 187 participants (59.4% females). The study sample had a mean age of 30.5 +/- 3.4 (range 25-45) years. The most popular subspecialty was movement disorders (18.2%), followed by multiple sclerosis (11.2%) and epilepsy (10.2%). This did not differ significantly between the participants who were or were not research oriented. CONCLUSIONS: There is a potential mismatch between the interests of trainees and the future needs of the populations they serve, which is important to identify for workforce planning. PMID- 29193503 TI - Mobile-based patient-provider communication in cancer survivors: The roles of health literacy and patient activation. AB - OBJECTIVE: Thanks to rapid penetration of mobile tools, more and more cancer survivors have adopted mobile-based patient-provider communication (MBPPC). The relationship between MBPPC and patients' health outcomes, however, remains unclear; how health literacy and patient activation interact with such relationship is unexplored. METHODS: Data were drawn from National Cancer Institute's Health Information National Trends Survey 4 Cycle 3. A sample of 459 cancer survivors were included in the analysis. Based on the 3-stage model of health promotion using interactive media, this study empirically tested a moderated mediation model. RESULTS: MBPPC (eg, patient use of email, text message, mobile app, and social media to communicate with providers) had no direct effect on cancer survivors' emotional health. Instead, health literacy completely mediated this path. Patient activation positively moderated the effect of health literacy on emotional health and further increased the indirect effect of MBPPC on emotional health. CONCLUSIONS: MBPPC alone does not directly result in better emotional health outcomes; health literacy is the key to realize its health benefits; patient activation significantly strengthens the effects of MBPPC. As we embrace the mHealth movement, innovative programs are needed to promote MBPPC, and improve health literacy and activation of cancer survivors, particularly in underserved communities, to reduce health disparities. PMID- 29193504 TI - Cohort-based income gradients in obesity among U.S. adults. AB - OBJECTIVES: No studies have focused on socioeconomic disparities in obesity within and between cohorts. Our objectives were to examine income gradients in obesity between birth-cohorts (inter-cohort variations) and within each birth cohort (intra-cohort variations) by gender and race/ethnicity. METHODS: Our sample includes 56,820 white and black adults from pooled, cross-sectional National Health and Nutrition Examination Surveys (1971-2012). We fit a series of logistic hierarchical Age-Period-Cohort models to control for the effects of age and period, simultaneously. Predicted probabilities of obesity by poverty-to income ratio were estimated and graphed for 5-year cohort groups from 1901-1990. We also stratified this relationship for four gender and racial/ethnic subgroups. RESULTS: Obesity disparities due to income were weaker for post-World War I and II generations, specifically the mid-1920s and the mid-1940s to 1950s cohorts, than for other cohorts. In contrast, we found greater income gradients in obesity among cohorts from the 1930s to mid-1940s and mid-1960s to 1970s. Moreover, obesity disparities due to income across cohorts vary markedly by gender and race/ethnicity. White women with higher income consistently exhibited a lower likelihood of obesity than those with lower income since early 1900s cohorts; whereas, black men with higher income exhibited higher risks of obesity than those with lower income in most cohorts. CONCLUSIONS: Our findings suggest that strategies that address race and/or gender inequalities in obesity should be cognizant of significant historical factors that may be unique to cohorts. Period based approaches that ignore life-course experiences captured in significant cohort-based experiences may limit the utility of policies and interventions.

AB - Diabetes occurs in 1/90 000 to 1/160 000 births and when diagnosed under 6 months of age is very likely to have a primary genetic cause. FOXP3 encodes a transcription factor critical for T regulatory cell function and mutations are known to cause "immune dysregulation, polyendocrinopathy (including insulin requiring diabetes), enteropathy, X-linked" (IPEX) syndrome. This condition is often fatal unless patients receive a bone-marrow transplant. Here we describe the phenotype of male neonates and infants who had insulin-requiring diabetes without other features of IPEX syndrome and were found to have mutations in FOXP3. Whole-exome or next generation sequencing of genes of interest was carried out in subjects with isolated neonatal diabetes without a known genetic cause. RT PCR was carried out to investigate the effects on RNA splicing of a novel intronic splice-site variant. Four male subjects were found to have FOXP3 variants in the hemizygous state: p.Arg114Trp, p.Arg347His, p.Lys393Met, and c.1044+5G>A which was detected in 2 unrelated probands and in a brother diagnosed with diabetes at 2.1 years of age. Of these, p.Arg114Trp is likely a benign rare variant found in individuals of Ashkenazi Jewish ancestry and p.Arg347His has been previously described in patients with classic IPEX syndrome. The p.Lys393Met and c.1044+5G>A variants are novel to this study. RT-PCR studies of the c.1044+5G>A splice variant confirmed it affected RNA splicing by generating both a wild type and truncated transcript. We conclude that FOXP3 mutations can cause early-onset insulin-requiring diabetes with or without other features of IPEX syndrome. PMID- 29193505 TI - A structural model of family empowerment for families of children with special needs. AB - AIMS AND OBJECTIVES: To explain and predict family empowerment in families of children with special needs. BACKGROUND: Family empowerment of families of children with special needs can be explained using the Double ABCX model. Although constant stressors such as parenting stress and family demands can have negative effects on family empowerment, family resources and parenting efficacy can mediate the negative effect through effective coping strategies. DESIGN: A cross-sectional research design was employed. METHODS: A survey was conducted with 240 parents of children with special needs. Upon exclusion of four responses deemed inadequate to the statistics process, 236 responses were selected for the analysis. Based on the items used in the previous research, we used the scale of family demands 38, the scale of parenting stress 24, the scale of parenting efficacy 37, the scale of pattern of organisation 30, the scale of communication process 16 and the scale of family empowerment 32. RESULTS: In families of children with special needs, parenting stress had a negative effect on parenting efficacy and family resources, namely, pattern of organisation and communication process. Family needs had a positive effect on parenting efficacy. Parenting stress and family demands influenced family empowerment through parenting efficacy and family resources (pattern of organisation and communication process), while parenting efficacy contributed to family empowerment. CONCLUSIONS: This study empirically analysed the usefulness of the Double ABCX model in predicting family empowerment. Family resource factors (organisation pattern and communication process) and perception or judgement factors (such as parenting efficacy) were found to mediate the negative impact of various stressors experienced by families of children with special needs. RELEVANCE TO CLINICAL PRACTICE: The study findings suggest that clinical practice and management should focus on providing efficient intervention methods to lower stress in families of children with special needs. Reinforcing factors contributing to family empowerment, such as parenting efficacy, organisation pattern and communication process, will alleviate families' stress, resulting in a positive educational and developmental impact on children with special needs. PMID- 29193506 TI - Synthesis and Stability of Lanthanum Superhydrides. AB - Recent theoretical calculations predict that megabar pressure stabilizes very hydrogen-rich simple compounds having new clathrate-like structures and remarkable electronic properties including room-temperature superconductivity. X ray diffraction and optical studies demonstrate that superhydrides of lanthanum can be synthesized with La atoms in an fcc lattice at 170 GPa upon heating to about 1000 K. The results match the predicted cubic metallic phase of LaH10 having cages of thirty-two hydrogen atoms surrounding each La atom. Upon decompression, the fcc-based structure undergoes a rhombohedral distortion of the La sublattice. The superhydride phases consist of an atomic hydrogen sublattice with H-H distances of about 1.1 A, which are close to predictions for solid atomic metallic hydrogen at these pressures. With stability below 200 GPa, the superhydride is thus the closest analogue to solid atomic metallic hydrogen yet to be synthesized and characterized. PMID- 29193507 TI - Incidence of antiemetic-induced akathisia in patients at a comprehensive cancer center. AB - INTRODUCTION: Akathisia is a common and severely disabling medication-induced movement disorder. The condition is often missed, and patients suffer for a long time until diagnosed and managed properly. It is important to bring awareness to the clinicians for early detection and management of akathisia. METHODS: We reviewed a 4-year record of patients seen at a comprehensive cancer center for anxiety and restlessness. Patients diagnosed with akathisia and the medications causing akathisia were identified. Management of akathisia is discussed. RESULTS: The results showed that 4.7% of patients developed akathisia while taking antiemetic agents to control chemotherapy-induced nausea/vomiting. Early detection and management of akathisia resulted in quick recovery and reduced patients' suffering. CONCLUSION: Akathisia is an unpleasant feeling of motor restlessness with anxiety. Clinicians need to have a full understanding to identify the subtle difference between functional anxiety and akathisia. PMID- 29193508 TI - Detection of liver fibrosis using qualitative and quantitative MR elastography compared to liver surface nodularity measurement, gadoxetic acid uptake, and serum markers. AB - BACKGROUND: Multiparametric magnetic resonance imaging (mpMRI) combining different techniques such as MR elastography (MRE) has emerged as a noninvasive approach to diagnose and stage liver fibrosis with high accuracy allowing for anatomical and functional information. PURPOSE: To assess the diagnostic performance of mpMRI including qualitative and quantitative assessment of MRE, liver surface nodularity (LSN) measurement, hepatic enhancement ratios postgadoxetic acid, and serum markers (APRI, FIB-4) for the detection of liver fibrosis. STUDY TYPE: IRB-approved retrospective. SUBJECTS: Eighty-three adult patients. FIELD STRENGTH/SEQUENCE: 1.5T and 3.0T MR systems. MRE and T1 -weighted postgadoxetic acid sequences. ASSESSMENT: Two independent observers analyzed qualitative color-coded MRE maps on a scale of 0-3. Regions of interest were drawn to measure liver stiffness on MRE stiffness maps and on pre- and postcontrast T1 -weighted images to measure hepatic enhancement ratios. Software was used to generate LSN measurements. Histopathology was used as the reference standard for diagnosis of liver fibrosis in all patients. STATISTICAL TESTS: A multivariable logistic analysis was performed to identify independent predictors of liver fibrosis. Receiver operating characteristic (ROC) analysis evaluated the performance of each imaging technique for detection of fibrosis, in comparison with serum markers. RESULTS: Liver stiffness measured with MRE provided the strongest correlation with histopathologic fibrosis stage (r = 0.74, P < 0.001), and the highest diagnostic performance for detection of stages F2-F4, F3-F4, and F4 (areas under the curve [AUCs] of 0.87, 0.91, and 0.89, respectively, P < 0.001) compared to other methods. Qualitative assessment of MRE maps showed fair to good accuracy for detection of fibrosis (AUC range 0.76-0.84). Multivariable logistic analysis identified liver stiffness and FIB-4 as independent predictors of fibrosis with AUCs of 0.90 (F2-F4), 0.93 (F3-F4) and 0.92 (F4) when combined. DATA CONCLUSION: Liver stiffness measured with MRE showed the best performance for detection of liver fibrosis compared to LSN and gadoxetic acid uptake, with slight improvement when combined with FIB-4.

PMID- 29193509 TI - The Narrowest Band Gap Ever Observed in Molecular Ferroelectrics: Hexane-1,6 diammonium Pentaiodobismuth(III). AB - Narrow band gaps and excellent ferroelectricity are intrinsically paradoxical in ferroelectrics as the leakage current caused by an increase in the number of thermally excited carriers will lead to a deterioration of ferroelectricity. A new molecular ferroelectric, hexane-1,6-diammonium pentaiodobismuth (HDA-BiI5 ), was now developed through band gap engineering of organic-inorganic hybrid materials. It features an intrinsic band gap of 1.89 eV, and thus represents the first molecular ferroelectric with a band gap of less than 2.0 eV. Simultaneously, low-temperature solution processing was successfully applied to fabricate high-quality ferroelectric thin films based on HDA-BiI5 , for which high-precision controllable domain flips were realized. Owing to its narrow band gap and excellent ferroelectricity, HDA-BiI5 can be considered as a milestone in the exploitation of molecular ferroelectrics, with promising applications in high density data storage and photovoltaic conversion.

In contrast, a bulky NHC ligand led to the para-selective alkylation of N-sec-alkyl anilides. PMID- 29193511 TI - Epidemiology of haemodialysis patients and haemodialysis performance in Nauru. AB - AIM: There is limited literature on haemodialysis in island countries in the Central Pacific. The primary aim of this study was to report on the epidemiology of haemodialysis patients and haemodialysis performance in Nauru. METHODS: We obtained registry data from the haemodialysis unit in Nauru to calculate the incidence rate, prevalence, and survival probability of haemodialysis patients in Nauru. We also reviewed medical records from January 2015 to February 2017 to evaluate the haemodialysis performance in Nauru. RESULTS: In total, 177 patients received long-term haemodialysis in the Nauru dialysis unit from 1987 to 2017. The 1-year, 2-year, and 5-year survival probabilities during the 30-year study period were 76.5%, 58.3% and 25.9%, respectively. From 2011 to 2014, the incidence rate and prevalence of treated end-stage renal disease in Nauru were significantly higher than Australia. From 2015 to 2017, there were 36 patients with a median age of 55 years who received long-term haemodialysis. Of these, 25 patients (69.4%) had diabetes. The median haemoglobin, serum albumin, and urea reduction ratio were 9.6 mg/dL, 35 g/L, and 64.7%, respectively. Multivariate analysis showed that lower serum albumin and lower urea reduction ratio were associated with mortality. CONCLUSION: To our knowledge, this is the first study to report the haemodialysis status in Nauru. The epidemiology of haemodialysis patients in Nauru is unique in Central Pacific. Improvement of primary health care in disease detection and prevention of progression should be considered to decrease the need for dialysis and optimise the care of haemodialysis patients in Nauru. PMID- 29193512 TI - Exertional hypoxemia is more severe in fibrotic interstitial lung disease than in COPD. AB - BACKGROUND AND OBJECTIVE: Despite its clinical and prognostic significance, few studies have evaluated the severity of exertional oxygen desaturation in fibrotic interstitial lung disease (ILD). Our objectives were to identify clinical and physiological variables that predict the extent of exertional oxygen desaturation in fibrotic ILD and to quantify the severity of desaturation compared to chronic obstructive pulmonary disease (COPD). METHODS: This retrospective study compared the results of 6-min walk test (6MWT) performed while breathing room air in fibrotic ILD patients and COPD patients eligible for pulmonary rehabilitation. Outcomes included the oxygen saturation (SpO2 ) nadir and the change in SpO2 from rest during a 6MWT. Predictor variables were identified on unadjusted analysis, followed by multivariate analysis to identify independent predictors of desaturation. RESULTS: The study included 134 patients with fibrotic ILD and 274 patients with COPD. The ILD and COPD cohorts had similar age, sex, frequency of major comorbidities, walk distance, baseline SpO2 and baseline Borg dyspnoea scores. DLCO was the strongest predictor of desaturation in both cohorts. Compared to patients with COPD, ILD patients had significantly lower SpO2 nadir values (88.1 +/- 6.4 vs 91.0 +/- 4.6) and greater decrease in SpO2 from baseline (7.4 +/- 5.2 vs 4.5 +/- 3.7) after adjusting for demographic features and pulmonary physiology (P < 0.0005), with greater between-group differences at lower DLCO values. CONCLUSION: Patients with fibrotic ILD have greater oxygen desaturation during 6MWT compared to patients with COPD when adjusting for demographic features and pulmonary physiology. These findings suggest the need for disease-specific studies to evaluate the potential utility of ambulatory oxygen in fibrotic ILD. PMID- 29193513 TI - Formalising the precepting process: A concept analysis of preceptorship. AB - AIMS AND OBJECTIVES: To elucidate the terminology associated with preceptorships, articulate an operational description of preceptorship that may be useful in formalising the precepting process and provide guidance for constructing a clinical environment where precepting can thrive. BACKGROUND: Precepting facilitates the transition of nurses into new roles. Precepting may improve patient outcomes and safety, as well as enhance nursing satisfaction. Most research focuses on preceptor preparation and perceptions. A comprehensive operational description of what is required to formalise the precepting process is missing from the literature. DESIGN: This concept analysis was completed using a combination of Walker and Avant's and Rodger's methods. METHODS: Existing literature relating to preceptorship was reviewed. Critical attributes, antecedents, consequences and empirical referents were identified. Model, contrary, related and borderline cases were developed. RESULTS: Preceptorships have the specific attributes of being (i) one-on-one relationships, (ii) embedded within formalised programmes, (iii) that evolve over set amounts of time, (iv) to systematically facilitate practical experiences. Antecedents include how precepting is triggered and organisational supporting activities that may facilitate effective precepting. Consequences include new hire preparedness, confidence and increased retention. Empirical referents are provided for assessing hands-on clinical expertise, individualisation of precepting programmes and the preceptor-preceptee relationship. CONCLUSIONS: This concept analysis provides a holistic view of the precepting process that shifts the focus from the people or checklist to formalised preceptorships. RELEVANCE TO CLINICAL PRACTICE: Continuity throughout an organisation's system streamlines the process of hiring new employees and transitioning nursing students to practice. Organisational policies, dedicated resources and engagement in systematically improving the precepting process are critical. Nurse managers must promote and support formalised preceptorships by providing preceptors and preceptees the time and space needed and fostering a culture that supports preceptorships. PMID- 29193514 TI - Kinetics of Thermal Polymerization Can Be Studied during Continuous Cooling. AB - It is demonstrated that differential scanning calorimetry can measure the kinetics of the thermally initiated polymerization during continuous cooling. The measurements are accomplished by switching from fast heating to much slower cooling. The study is exemplified by crosslinking polymerization (curing) of diglycidyl ether of bisphenol A epoxy and m-phenylenediamine taken in stoichiometric and nonstoichiometric ratios and measured under heating and cooling conditions. An advanced isoconversional method reveals that the reaction in the nonstoichiometric system follows the kinetics of the single-step type. Its activation energy is constant and the same for heating and cooling conditions. The stoichiometric system exhibits the multistep kinetics characterized by the dependencies of the activation energy on temperature that differ qualitatively for cooling and heating runs. The discovered differences emphasize the need for further systematic studies of the thermal polymerization during continuous cooling.

AB - The site-selective dearomatization of naphthols is realized in a straightforward manner through a gold(I)-catalyzed [3,3]-sigmatropic rearrangement/allene functionalization cascade sequence. The method employs readily available naphthylpropargyl ethers as starting materials. A range of densely functionalized dihydrofurylnaphthalen-2(1H)-ones are obtained in high yields (up to 98 %) and extremely mild reaction conditions (reagent grade solvent, air, 10 minute reaction time). A complete theoretical elucidation of the reaction machinery is also proposed, providing a rationale for important issues such as regio- and chemoselectivity. PMID- 29193516 TI - The effectiveness of clinical pathway-directed care on hospitalisation-related outcomes in patients with severe traumatic brain injury: A quasi-experimental study. AB - AIMS AND OBJECTIVES: To compare the effectiveness of clinical pathway-directed care to usual care on hospitalisation-related outcomes in patients with severe traumatic brain injury (STBI). BACKGROUND: Severe traumatic brain injury is a major cause of disability and mortality in young adults. Clinical pathways endeavour to bring evidence and clinical practice closer together to foster the delivery of best practice and to improve patient outcomes. DESIGN: Quasi experimental study. METHODS: The study was conducted in a trauma intensive care unit of a large teaching hospital in Egypt. Patients aged 18-60 years with a diagnosis of STBI, a Glasgow Coma Scale score between 3-8 and a nonpenetrating head injury were consecutively assigned to 15 days of care. The outcomes assessed were complications related to hospitalisation, clinical variances, length of intensive care unit (ICU) stay, ICU readmission rate and patient/family satisfaction. RESULTS: Sixty participants completed the study (30 in each arm). Apart from age, there were no significant differences between groups in baseline characteristics. The clinical pathway group demonstrated statistically significantly fewer cases of hospitalisation-related complications on day 15, and a significantly shorter length of ICU stay, lower ICU readmission rate and a high level of patient/family satisfaction when compared with the usual care group. The effect of the intervention on fever, pressure ulceration, hyperglycaemia and readmission to the ICU was no longer statistically significant after controlling for age. CONCLUSIONS: The findings of the current study suggest that the implementation of a clinical pathway for patients with severe TBI may be helpful in improving the patient experience as well as some hospitalisation-related outcomes. RELEVANCE TO CLINICAL PRACTICE: The provision of clinical pathway directed care in a trauma ICU may offer benefits to the patient, family and institution beyond that provided by usual care. PMID- 29193517 TI - Biological consequences of improving the structural stability of hairpins that have antimicrobial activity. AB - Designing new antimicrobial peptides (AMPs) focuses heavily on the activity of the peptide and less on the elements that stabilize the secondary structure of these peptides. Studies have shown that improving the structure of naturally occurring AMPs can affect activity and so here we explore the relationship between structure and activity of two non-naturally occurring AMPs. We have used a backbone-cyclized peptide as a template and designed an uncyclized analogue of this peptide that has antimicrobial activity. We focused on beta-hairpin-like structuring features. Improvements to the structure of this peptide reduced the activity of the peptide against gram-negative, Escherichia coli but improved the activity against gram-positive, Corynebacterium glutamicum. Distinctions in structuring effects on gram-negative versus gram-positive activity were also seen in a second peptide system. Structural improvements resulted in a peptide that was more active than the native against gram-positive bacterium but less active against gram-negative bacterium. Our results show that there is not always a correlation between improved hairpin-structuring and activity. Other factors such as the type of bacteria being targeted as well as net positive charge can play a role in the potency of AMPs.

AB - Natural peptides with antimicrobial activity are extremely diverse, and peptide synthesis technologies make it possible to significantly improve their properties for specific tasks. Here, we investigate the biological properties of the natural peptide indolicidin and the indolicidin-derived novel synthetic peptide In-58. In 58 was generated by replacing all tryptophan residues on phenylalanine in D configuration; the alpha-amino group in the main chain also was modified by unsaturated fatty acid. Compared with indolicidin, In-58 is more bactericidal, more resistant to proteinase K, and less toxic to mammalian cells. Using molecular physics approaches, we characterized the action of In-58 on bacterial cells at the cellular level. Also, we have found that studied peptides damage bacterial membranes. Using the Escherichia coli luminescent biosensor strain MG1655 (pcolD'::lux), we investigated the action of indolicidin and In-58 at the subcellular level. At subinhibitory concentrations, indolicidin and In-58 induced an SOS response. Our data suggest that indolicidin damages the DNA, but bacterial membrane perturbation is its principal mode of action.

AB - N-Acyliminoiodinanes were characterized for the first time by X-ray structural analysis. The ortho-methoxymethyl group and the carbonyl oxygen coordinate to the iodine atom of the iminoiodinane. Activation of the N-acyliminoiodinane was achieved by photoirradiation at 370 nm, thereby enabling reaction with various silyl enol ethers to give alpha-aminoketone derivatives in good to high yield. N sulfonyliminoiodinanes bearing ortho substituents were used in photoinduced amination. PMID- 29193520 TI - Physiological significance of multipolar cells generated from neural stem cells and progenitors for the establishment of neocortical cytoarchitecture. AB - Neurogenesis encompasses an entire set of events that leads to the generation of newborn neurons from neural stem cells and more committed progenitor cells, including cell division, the production of migratory precursors and their progeny, differentiation and integration into circuits. In particular, the precise control of neuronal migration and morphological changes is essential for the development of the neocortex. Postmitotic cells within the intermediate zone have been found to transiently assume a characteristic "multipolar" morphology, after which a multipolar-to-bipolar transition occurs before the cells enter the cortical plate; however, the importance of this multipolar phase in the establishment of mature cortical cytoarchitecture and the precise genetic control of this phase remains largely unknown. Thus, this review article focuses on the multipolar phase in the developing neocortex. It begins by summarizing the molecular mechanism that underlies multipolar migration for the regulation of each step in multipolar phase in intermediate zone. The physiological significance of this multipolar phase in the establishment of mature cortical lamination and neurodevelopmental disorders associated with migration defects is then described.

AB - The 3rd International Insect Hormone (21st Ecdysone) Workshop (IIHW2017) was held in July 2017 at Nasu Highland, Japan. In the 40 years of the workshop's history, this was the first to be held in an Asian country. A total of 109 insect hormone researchers from 18 countries (62 overseas and 47 domestic participants) attended IIHW2017. During the workshop, all participants stayed on-site at the venue's hotel; this was ideal for fostering communication between participants, in particular, interactions between principal investigators and young scientists. The workshop featured one keynote, 64 oral, and 35 poster presentations spanning molecular biology, cell biology, developmental biology, neurobiology, chemical biology, physiology, and ecology of insect hormones, including ecdysteroids, juvenile hormones, and a variety of neuropeptides. The workshop provided an ideal platform for discussing insect hormone biology using not only the typical genetic model insect, the fruit fly Drosophila, but also a diversity of interesting insects, such as the silkworm, the red flour beetle, the cricket, the dragonfly, the social ant, the bloodsucking tick, and so on. The participants succeeded in sharing the latest knowledge in a wide range of insect hormone research fields and in joining active and constructive scientific discussions.

Mechanistic studies suggest the intermediacy of carbon-centered radicals. PMID- 29193524 TI - Effect of Site-Specific Peptide-Tag Labeling on the Biocatalytic Properties of Thermoalkalophilic Lipase from Geobacillus thermocatenulatus. AB - Tailor-made peptides were investigated for site-specific tag labeling of Geobacillus thermocatenulatus lipase (GTL). GTL was first genetically modified by introducing a unique cysteine on the lid site of the enzyme to produce two variants (GTLsigma-A193C and GTLsigma-S196C). Chemical modification was performed by using a small library of cysteine-containing peptides. The synthesized peptide lipase biocatalysts were highly stable, more active, more specific, and more selective toward different substrates than unmodified GTL. Very high enzyme thermostability of GTLsigma-A193C modified with peptides Ac-Cys-Phe-Gly-Phe-Gly Phe-CONH2 (1) and Ac-Cys-Phe-Phe-CONH2 (2) (>95 % activity after 24 h at 60 degrees C) was observed. The incorporation of 1 and 2 in GTLsigma-S196C improved its catalytic activity in the hydrolysis of p-nitrophenyl butyrate by factors of three and greater than five, respectively. The specificity for short-chain versus long-chain esters was also strongly improved. The diacylglycerol activity of GTLsigma-S196C was enhanced more than tenfold by the incorporation of 1 and more than threefold by modification of this variant with Ac-Cys-(Arg)7 -CONH2 (6) in the hydrolysis of 1-stearoyl-2-arachidonoyl-sn-glycerol. The enantioselectivity of GTLsigma-S196C increased for all formed bioconjugates, and the GTLsigma-S196C 1 conjugate was the most active and selective in the hydrolysis of dimethylphenyl glutarate at pH 7 (72 % ee), also showing an inversion in the enzyme enantiopreference. PMID- 29193525 TI - Triple Bonds Between Iron and Heavier Group 15 Elements in AFe(CO)3- (A=As, Sb, Bi) Complexes. AB - Heteronuclear transition-metal-main-group-element carbonyl complexes of AsFe(CO)3 , SbFe(CO)3- , and BiFe(CO)3- were produced by a laser vaporization supersonic ion source in the gas phase, and were studied by mass-selected IR photodissociation spectroscopy and advanced quantum chemistry methods. These complexes have C3v structures with all of the carbonyl ligands bonded on the iron center, and feature covalent triple bonds between bare Group 15 elements and Fe(CO)3- . Chemical bonding analyses on the whole series of AFe(CO)3- (A=N, P, As, Sb, Bi, Mc) complexes indicate that the valence orbitals involved in the triple bonds are hybridized 3d and 4p atomic orbitals of iron, leading to an unusual (dp-p) type of transition-metal-main-group-element multiple bonding. The sigma-type three-orbital interaction between Fe 3d/4p and Group 15 np valence orbitals plays an important role in the bonding and stability of the heavier AFe(CO)3- (A=As, Sb, Bi) complexes. PMID- 29193523 TI - Barriers to medication adherence and links to cardiovascular disease risk factor control: the Framingham Heart Study. AB - BACKGROUND: In the elderly, impaired cognition may weaken medication adherence and compromise treatment for cardiovascular disease (CVD). AIM: We examined risk factors for medication adherence and the relationship between adherence and levels of CVD risk factors among older participants with hypertension, dyslipidaemia and diabetes in the Framingham Heart Study. METHODS: The four-item Morisky Medication Adherence Scale was administered to 1559 participants, median age 70 years, 53% women. We created an adherence score, ranging from 0 to 4, with low adherence defined as a score >=2. CVD risk factors were assessed using standard protocols. Cognition was measured using the Mini-Mental State Examination (MMSE) and depressive symptoms were measured using the Center for Epidemiologic Studies of Depression (CES-D) scale. RESULTS: Among participants who self-reported taking antihypertensive, lipid-lowering and/or hyperglycaemic medication(s), 12% (n = 191) had low medication adherence. The risk of low adherence increased by 45% (95% confidence interval (CI): 25-68%, P < 0.001) per five-unit increase in CES-D score. In participants taking antihypertensive medication (n = 1017), low adherence was associated with higher mean diastolic blood pressure (73 mmHg, 95% CI: 71-75 vs 71 mmHg, 95% CI: 70-71; P = 0.04) after adjusting for covariates. Among participants taking lipid-lowering medication (n = 937), low adherence was associated with higher mean low-density lipoprotein cholesterol (92 mg/dL, 95% CI: 87-96 vs 86 mg/dL, 95% CI: 84-88; P = 0.03). Low adherence was not associated with fasting plasma glucose (P = 0.10) or haemoglobin A1c (P = 0.68) in the subgroup of participants (n = 192) taking hypoglycaemic medication. CONCLUSIONS: Depressive symptoms might act as a barrier for medication adherence, which exacerbates CVD risk factors in older-aged adults. PMID- 29193526 TI - Triple phase computed tomography of the pancreas in healthy cats. AB - While the availability and use of computed tomography (CT) continues to grow, no study has described the size and multiphase CT appearance of the normal feline pancreas. This information is important to not only allow more accurate identification and differentiation of disease, but it may also be useful in assessing pancreatic function. In this prospective analytical study, we described a triple phase CT protocol of the pancreas for use in sedated cats and the attenuation, enhancement pattern, size, and volume of the pancreas for a group of healthy cats. Fifteen healthy cats were enrolled in the study and a standardized protocol for acquiring arterial, portal, and delayed phase CT images of the pancreas was developed and described. The pancreas was hypo to isoattenuating to both the liver and spleen in all phases in the majority of cats with a homogenous enhancement pattern noted in all 15. Mean pancreatic attenuation was 48, 79, 166, and 126 Hounsfield units (HU) respectively on precontrast, arterial, portal, and delayed phase images. In addition, mean height, length, and width of the left lobe of the pancreas were larger than the right lobe in all 15 cats. There were no associations between volume and volume: body weight ratio with age (P = 0.6518, P = 0.6968) or sex (P = 0.7013, P = 0.2043). This baseline information may be beneficial for use in future studies characterizing pancreatic disease in cats as well as future research studies evaluating pancreatic endocrine function.

BACKGROUND: Contextual factors are found to be important when applying technology in health care and applying telemedicine in home-based care has been identified as particularly complex. DESIGN AND METHODS: We conducted field observations and individual interviews among healthcare professionals in home-based care and specialist health care in a diabetes foot care telemedicine RCT (Clin.Trial.gov: NCT01710774) during 2016. This study was guided by Interpretive Description, an inductive qualitative methodology. RESULTS: Overall, we identified unequal possibilities for applying telemedicine in diabetes foot ulcer care within the hospital and home care contexts. Different circumstances and possibilities in home-based care made the application of telemedicine as intended more difficult. The healthcare professionals in both care contexts perceived the application of telemedicine to facilitate a more comprehensive approach towards the patients, but with different possibilities to enact it. CONCLUSIONS: Application of telemedicine in home-based care was more challenging than in the outpatient clinic setting. Introducing more updated equipment and minor structural adjustments in consultation time and resources could make the use of telemedicine in home-based care more robust. RELEVANCE TO CLINICAL PRACTICE: Application of telemedicine in diabetes foot ulcer follow-up may enhance the nursing staff's ability to conduct comprehensive assessment and care of the foot ulcer as well as the patient's total situation. Access to adequate equipment and time, particularly in home-based care, is necessary to capitalise on this new technology.

AB - In this study, we aimed to investigate relaxant effect of flavanol (-) epicatechin on the isolated human saphenous vein (HSV), as a part of its cardioprotective action, and to define the mechanisms underlying this vasorelaxation. (-)-Epicatechin induced a concentration-dependent relaxation of HSV pre-contracted by phenylephrine. Among K+ channel blockers, 4-aminopyridine, margatoxin, and iberiotoxin significantly inhibited relaxation of HSV, while glibenclamide considerably reduced effects of the high concentrations of (-) epicatechin. Additionally, (-)-epicatechin relaxed contraction induced by 80 mM K+ , whereas in the presence of nifedipine produced partial relaxation of HSV rings pre-contracted by phenylephrine. In Ca2+ -free solution, (-)-epicatechin relaxed contraction induced by phenylephrine, but had no effect on contraction induced by caffeine. A sarcoplasmic reticulum Ca2+ -ATPase inhibitor, thapsigargin, significantly reduced relaxation of HSV produced by (-) epicatechin. These results demonstrate that (-)-epicatechin produces endothelium independent relaxation of isolated HSV rings. Vasorelaxation to (-)-epicatechin probably involves activation of 4-aminopyridine- and margatoxin-sensitive KV channels, BKCa channels, and at least partly, KATP channels. In addition, not only the inhibition of extracellular Ca2+ influx, but regulation of the intracellular Ca2+ release, via inositol-trisphosphate receptors and reuptake into sarcoplasmic reticulum, via stimulation of Ca2+ -ATPase, as well, most likely participate in (-)-epicatechin-induced relaxation of HSV. PMID- 29193529 TI - Renal ultrasound and Doppler parameters as markers of renal function and histopathological damage in children with chronic kidney disease. AB - AIM: Doppler ultrasonography can be used to assess the progression of vascular (arterial sclerosis) and parenchymal (glomerular sclerosis and crescents) renal damage. The aim of this study was to evaluate the significance of some sonographic and Doppler parameters as non-invasive markers of glomerular filtration rate (GFR) and renal histopathological damage in children. METHODS: A cohort of 84 children were enrolled in a case-control study (42 with CKD stages 2 5 and 42 healthy children). GFR was assessed using new improved equation using serum creatinine and cystatin C. Sonar guided renal specimen was obtained and evaluated for the severity of global sclerosis (GS), segmental sclerosis (SS), tubular atrophy (TA), interstitial fibrosis (IF), arterial sclerosis (AS) and arteriolar hyalinosis (AH). The following sonographic and Doppler parameters were assessed in both patients and control group: resistivity index (RI), pulsatility index (PI), atrophic index (AI), mean renal volume, mean renal density, time average velocity (TAV) and body surface area related volume perfusion (BSARVP). RESULTS: There was significant difference in renal density (P < 0.001), RI (P < 0.001), PI (P = 0.021), TAV (P < 0.001) and BSARVP (P < 0.001) between patients and control group. The cutoff value of RI was 63.5% (sensitivity 83% and specificity 64%). Multivariate analysis revealed that renal density and RI were significant predictors of worsening of estimated GFR (eGFR) in CKD patients. CONCLUSION: Any increase in the RI and PI values must arouse alarm to the possibility of advancing renal damage. Moreover, RI and PI could fairly predict the degree of glomerular sclerosis and interstitial fibrosis.

AB - Two kinds of shape-controllable and fluorescent supramolecular organic frameworks (cuboid or spheroid) are constructed hierarchically from CB[8] and tetraphenylethylene derivatives through host-guest interaction in water. These two fluorescent SOFs exhibit intriguing and varied photophysical properties, including large red-shifts (up to 82 nm) and stimuli-responsive behavior to competitive guest by binding with CB[8], the turn-on fluorescence of which is applied in cellular imaging. PMID- 29193531 TI - High-voltage electrical injury: Modified surgical technique for optimal defect closuring of extra-large cranial defect. AB - Electrical burns are group of traumatic injuries with a mortality rate of 3-15%. High-voltage induced extensive electric burns are rarely seen in the cranial area, compared to upper and lower limbs, but extremely difficult for treatment, due to the limited flexibility in this area. The spectrum of therapeutic interventions in electrical burns in general, evolving initial necrectomy, decompression, and aggressive debridement with early skin coverage is usually not enough in cases of extensive cranial defects. The performance of a suitable flap combined with skin graft in donor site, and further implantation of expander is challenging in this area. We present a case of a high-voltage induced extra-large cranial injury in a 38-year-old man, treated with modified single large rotation flap and a split skin-thickness graft technique, for optimal defect closuring with satisfied aesthetic result.

AB - OBJECTIVES: To analyze whether living conditions, experienced by mothers and adult daughters during their childhood, are associated with age at menarche (AAM) in daughters. METHODS: From September, 2011, to January, 2014, AAM and childhood living conditions were collected from a sample of 246 dyads of Maya mothers (mean age = 59.60 years, SD = 8.64) and their adult daughters (mean age = 33.03 years, SD = 5.57) from the cities of Merida and Motul in Yucatan, Mexico. Indicators of childhood living conditions were number of siblings and quality of house construction materials in both generations, and father's absence among daughters in their pre-menarcheal years. Multiple regression models were used to assess the association between childhood conditions in mother-daughter dyads and daughter's AAM. RESULTS: The recalled mean AAM of adult Maya daughters was 12.05 years (SD = 1.53). After adjusting for the influence of mothers' AAM, number of siblings in both the mothers' and daughters' families directly predicted daughters' AAM (more siblings was associated with a later AAM); and a higher (better) index of household conditions in mothers' childhood was associated with earlier AAM in daughters. The household conditions index during the childhood of daughters and father's absence were not associated with their AAM. CONCLUSIONS: Our results suggest that better living conditions experienced by the mothers and daughters during their childhood may lower mean AAM in daughters in the context of populations that show important intergenerational changes in their social and economic conditions. PMID- 29193534 TI - DMSO as a mobile phase additive enhances detection of ubiquitination sites by nano-LC-ESI-MS/MS. AB - Large-scale detection of ubiquitination sites in whole cell proteomes using nano liquid chromatography coupled to tandem mass spectrometry is a well-established technique that has deepened the understanding of protein degradation processes in eukaryotic cells. Ubiquitination sites are usually identified by detection of Lys E-Gly-Gly (K-E-GG)-remnant peptides, which are generated by tryptic digestion of proteomes. We show in this application note that dimethyl sulfoxide addition to the liquid chromatography mobile phase enhances identification rates of K-E-GG peptides by more than 100% due to an increase of peptide signal intensities. The gain in the number of ubiquitination site identifications exceeds by far the gain that has been published for other posttranslational modifications, namely, phosphorylation and acetylation. PMID- 29193535 TI - Monodisperse N-Doped Graphene Nanoribbons Reaching 7.7 Nanometers in Length. AB - The properties of graphene nanoribbons are highly dependent on structural variables such as width, length, edge structure, and heteroatom doping. Therefore, atomic precision over all these variables is necessary for establishing their fundamental properties and exploring their potential applications. An iterative approach is presented that assembles a small and carefully designed molecular building block into monodisperse N-doped graphene nanoribbons with different lengths. To showcase this approach, the synthesis and characterisation of a series of nanoribbons constituted of 10, 20 and 30 conjugated linearly-fused rings (2.9, 5.3, and 7.7 nm in length, respectively) is presented. PMID- 29193536 TI - Temporal trend and risk determinants of hepatocellular carcinoma in chronic hepatitis B patients on entecavir or tenofovir. AB - This study aimed to elucidate the temporal change and determinants for the risk of HCC in patients with chronic hepatitis B continuously receiving NUC. Through analysis of the national healthcare database in Taiwan, we screened a total of 65 426 infected patients receiving entecavir or tenofovir for at least 3 months and excluded those with lamivudine, adefovir or telbivudine exposure, malignancy, end stage renal failure or a diagnosis of HCC within 3 months of starting treatment. Eligible patients (N = 27 820) were followed until HCC occurrence, completion of the allowed 3-year regimen or 31 December 2013. During a median follow-up of 25.1 (12.1-35.6) months, 802 patients developed HCC, with 1-, 2- and 3-year cumulative incidence of 1.82% (95% CI, 1.66-1.99%), 3.05% (95% CI, 2.82-3.28%) and 4.06% (95% CI, 3.77-4.36%), respectively. HCC annual incidence decreased with an adjusted IRR of 0.73 (95% CI, 0.66-0.80) per yearly interval and was associated with cirrhosis (IRR, 10.07; 95% CI, 6.00-16.90 in age <40 years; 4.69; 95% CI, 3.94-5.59 in age ?40 years), age (IRR, 3.38; 95% CI, 2.10-5.47 for 40-50 years; 6.92; 95% CI, 4.27-11.21 for 50-60 years; 12.50; 95% CI, 7.71-20.25 for ?60 years; <40 years as reference), male sex (IRR, 1.71; 95% CI, 1.44-2.04), HCV coinfection (IRR, 1.27; 95% CI, 1.02-1.58) and diabetes (IRR, 1.24; 95% CI, 1.05 1.45). In conclusion, the risk of HCC in patients with chronic hepatitis B receiving entecavir or tenofovir declines over time and is determined by cirrhosis, age, male sex, HCV coinfection and diabetes. PMID- 29193537 TI - E-cigarette price sensitivity among middle- and high-school students: evidence from monitoring the future. AB - AIMS: We estimated associations between e-cigarette prices (both disposable and refill) and e-cigarette use among middle and high-school students in the United States. We also estimated associations between cigarette prices and e-cigarette use. DESIGN: We used regression models to estimate the associations between e cigarette and cigarette prices and e-cigarette use. In our regression models, we exploited changes in e-cigarette and cigarette prices across four periods of time and across 50 markets. We report the associations as price elasticities. In our primary model, we controlled for socio-demographic characteristics, cigarette prices, tobacco control policies, market fixed effects and year-quarter fixed effects. SETTING: United States of America. PARTICIPANTS: A total of 24 370 middle- and high-school students participating in the Monitoring the Future Survey in years 2014 and 2015. MEASUREMENTS: Self-reported e-cigarette use over the last 30 days. Average quarterly cigarette prices, e-cigarette disposable prices and e-cigarette refill prices were constructed from Nielsen retail data (inclusive of excise taxes) for 50 US markets. FINDINGS: In a model with market fixed effects, we estimated that a 10% increase in e-cigarette disposable prices is associated with a reduction in the number of days vaping among e-cigarette users by approximately 9.7% [95% confidence interval (CI) = -17.7 to 1.8%; P = 0.02] and is associated with a reduction in the number of days vaping by the full sample by approximately 17.9% (95% CI = -31.5 to -4.2%; P = 0.01). Refill e cigarette prices were not statistically significant predictors of vaping. Cigarette prices were not associated significantly with e-cigarette use regardless of the e-cigarette price used. However, in a model without market fixed effects, cigarette prices were a statistically significant positive predictor of total e-cigarette use. CONCLUSIONS: Higher e-cigarette disposable prices appear to be associated with reduced e-cigarette use among adolescents in the US. PMID- 29193538 TI - Diversity of Polyketide Chains Achieved by Deleting the Tailoring Genes in the Biosynthesis of Ansatrienins. AB - The ast gene cluster (GenBank accession numbers KF813023.1 and KP284551) was characterized to be responsible for the biosynthesis of ansatrienins in Streptomyces sp. XZQH13, which contains astC, astF1, and astF2 genes involved in the assembly of the N-cyclohexanoyl d-alanyl side chain and the hydroxylation of C-19, respectively. Further to investigating the biosynthetic mechanism of ansatrienins, herein we constructed the mutant strains XZQH13OEDeltaastF2 and XZQH13OEDeltaastCDeltaastF2. Three new ansatrienin analogues, namely, ansatrienols I-K (1-3), along with trienomycinol (4) and 3-O demethyltrienomycinol (5), were isolated from the XZQH13OEDeltaastCDeltaastF2 strain, and trienomycin A (6) and trienomycin G (7) were isolated from the XZQH13OEDeltaastF2 strain. Their structures were determined by a combination of high-resolution MS (ESI) and 1D and 2D NMR spectroscopy. Accordingly, a pathway for the biosynthesis of these new ansatrienins was proposed. PMID- 29193539 TI - Comprehensive evaluation of the role of soy and isoflavone supplementation in humans and animals over the past two decades. AB - Soy and soy-based foods are considered healthy, particularly in many Asia-Pacific countries, where soy products have long been consumed. Soy and soy-related products have been found to help prevent the occurrence of cardiovascular diseases and certain types of cancer, such as breast and prostate cancer. These products can also have antioxidative effects that alleviate hot flashes during menopause and bone loss. These biological and therapeutic functions are primarily due to the isoflavones derived from soy, whose structure is similar to the structure of 17-beta-oestradiol. Despite the many health benefits for humans and animals, the application of isoflavones remains controversial because of their anti-oestrogenic properties. We focused on general information regarding isoflavones, as well as their structure, function, and application. We summarized evidence showing that dietary or supplemental isoflavones exert protective effects on the health of humans and animals. Based on the literature, we conclude that soy foods and isoflavones may be effective and safe; however, more high quality trials are needed to fully substantiate their potential use. PMID- 29193540 TI - The proportion of familial cases of type 1 diabetes is increasing simultaneously with the disease incidence: Eighteen years of the Israeli Pediatric Diabetes Registry. AB - BACKGROUND: The global rise in incidence of type 1 diabetes (T1D) is too rapid to be attributed to susceptible genetic background, pinpointing a significant role for environmental factors. Unlike the theory that the need for genetic susceptibility has lessened over time, we hypothesized that the rise in T1D incidence is faster in a genetically susceptible population. SUBJECTS AND METHODS: The study population comprised of 5080 patients aged 0 to 17 years who were reported to the National Israel Diabetes Registry between 1997 and 2014. The patients were divided into familial cases (first-degree relative has T1D), and sporadic cases. Demographic and clinical data were retrieved from the registry. The change in annual percent (from the entire cohort) was computed separately for the sporadic and familial cohorts. RESULTS: The familial (n = 546; 10.7%) and sporadic (n = 4534; 89.3%) cases were comparable for gender, ethnicity, and age at diagnosis. Consanguinity was more common in the familial vs sporadic group (10% vs 6.1%; P = .001). The average annual percent change increased by 1.9% in the familial cases and decreased by 0.2% in the sporadic cases (P = .04). CONCLUSIONS: The rapid rise in the proportion of familial cases of T1D suggests that environmental factors impose higher diabetogenic pressure in patients with a susceptible genetic background. PMID- 29193541 TI - Nitrogen use efficiency is regulated by interacting proteins relevant to development in wheat. AB - Wheat (Triticum aestivum) has low nitrogen use efficiency (NUE). The genetic mechanisms controlling NUE are unknown. Positional cloning of a major quantitative trait locus for N-related agronomic traits showed that the vernalization gene TaVRN-A1 was tightly linked with TaNUE1, the gene shown to influence NUE in wheat. Because of an Ala180 /Val180 substitution, TaVRN-A1a and TaVRN-A1b proteins interact differentially with TaANR1, a protein encoded by a wheat orthologue of Arabidopsis nitrate regulated 1 (ANR1). The transcripts of both TaVRN-A1 and TaANR1 were down-regulated by nitrogen. TaANR1 was functionally characterized in TaANR1::RNAi transgenic wheat, and in a natural mutant with a 23 bp deletion including 10-bp at the 5' end of intron 5 and 13-bp of exon 6 in gDNA sequence in its gDNA sequence, which produced transcript that lacked the full 84 bp exon 6. Both TaANR1 and TaHOX1 bound to the Ala180 /Val180 position of TaVRN A1. Genetically incorporating favourable alleles from TaVRN-A1, TaANR1 and TaHOX1 increased grain yield from 9.84% to 11.58% in the field. Molecular markers for allelic variation of the genes that regulate nitrogen can be used in breeding programmes aimed at improving NUE and yield in novel wheat cultivars. PMID- 29193542 TI - Improved performance of quantitative collagen parameters versus standard histology in longitudinal assessment of nonadvanced liver fibrosis for chronic hepatitis B. AB - Monitoring longitudinal nonadvanced fibrosis is a more common scenario in management of chronic hepatitis B (CHB), for which, however, current evaluation methods generally lack sufficient performance. We conducted a proof-of-concept study to evaluate the performance of quantitative fibrous collagen parameters (q FP) in the assessment. Data sets from a prior CHB trial (NCT00962533) with mostly mild-to-moderate fibrosis participants were used for this study. 301 subjects with paired liver biopsies were consecutively included. Of these, 139 subjects were used to establish the test and the rest for internal validation. Fibrosis change between baseline and week 104 of treatment was blindly assessed with q-FP and was compared with Ishak fibrosis staging. There were 70% and 93% subjects with Ishak F0-2 at baseline and week 104, respectively. For the test of the subjects, q-FP and Ishak staging showed no difference in determining the incidence of fibrosis regression (68% vs 67%; difference = 0.7%, P = 1.00). Q-FP demonstrated that the regression was independently associated with the antiviral efficacy endpoint (OR 3.0, 95% CI 1.4-6.5, P = .005), but Ishak failed the detection (OR 0.6, 95% CI 0.3-1.3, P = .24). Moreover, q-FP directly revealed a higher fibrosis-resistance to antiviral treatment in virus genotypes C vs B and in males vs females. These results were confirmed in the validation subjects. Additionally, a functional model built on the test subjects showed an accuracy of 82% in stratifying fibrosis reversibility of the validation subjects. In conclusion, q-FP could have improved efficiency and accuracy in the longitudinal assessment of mild-to-moderate CHB fibrosis, indicating a potential alternative to current evaluation methodologies. PMID- 29193543 TI - Initiation of dapagliflozin and treatment-emergent fractures. AB - An increase in fracture risk has been reported in patients with type 2 diabetes mellitus (T2DM) treated with canagliflozin, possibly mediated by effects induced by all members of the sodium-glucose co-transporter-2 (SGLT2) inhibitor class. It is unclear whether initiation of dapagliflozin is followed by an increase in the risk of fracture; therefore, we performed a population-based, open cohort study (from January 2013 to January 2016) using The Health Improvement Network (THIN). A total of 22 618 people with T2DM (4548 exposed to dapagliflozin and 18 070 receiving standard antidiabetic treatment, matched for age, sex, body mass index and diabetes duration) with no history of fractures at baseline were included. The primary outcome was the occurrence of any fragility fracture (hip, spine, wrist) during the observation period. Risk of any fracture served as a secondary outcome. Adjusted hazard rate ratios (HRs) with 95% confidence intervals (CIs) were calculated using Cox regression. A total of 289 fractures (132 fragility fractures) were recorded. No difference in the risk of fragility fracture was detected between participants prescribed dapagliflozin and matched control participants (crude HR 0.90, 95% CI 0.59-1.39, P = .645; adjusted HR 0.87, 95% CI 0.56-1.35, P = .531). Similarly, no difference in the risk of any fracture was detected (adjusted HR 0.89, 95% CI 0.66-1.20; P = .427). Sensitivity analyses limited to the subset of the population at high risk of fracture produced similar results; thus, there was no evidence to suggest an increase in the risk of treatment-emergent fractures in patients with T2DM who initiated treatment with dapagliflozin. PMID- 29193544 TI - Characterisation of a Bacterial Galactokinase with High Activity and Broad Substrate Tolerance for Chemoenzymatic Synthesis of 6-Aminogalactose-1-Phosphate and Analogues. AB - Glycosyl phosphates are important intermediates in many metabolic pathways and are substrates for diverse carbohydrate-active enzymes. Thus, there is a need to develop libraries of structurally similar analogues that can be used as selective chemical probes in glycomics. Here, we explore chemoenzymatic cascades for the fast generation of glycosyl phosphate libraries without protecting-group strategies. The key enzyme is a new bacterial galactokinase (LgGalK) cloned from Leminorella grimontii, which was produced in Escherichia coli and shown to catalyse 1-phosphorylation of galactose. LgGalK displayed a broad substrate tolerance, being able to catalyse the 1-phosphorylation of a number of galactose analogues, including 3-deoxy-3-fluorogalactose and 4-deoxy-4-fluorogalactose, which were first reported to be substrates for wild-type galactokinase. LgGalK and galactose oxidase variant M1 were combined in a one-pot, two-step system to synthesise 6-oxogalactose-1-phosphate and 6-oxo-2-fluorogalactose-1-phosphate, which were subsequently used to produce a panel of 30 substituted 6 aminogalactose-1-phosphate derivatives by chemical reductive amination in a one pot, three-step chemoenzymatic process. PMID- 29193545 TI - Identification and Characterization of a Single High-Affinity Fatty Acid Binding Site in Human Serum Albumin. AB - A single high-affinity fatty acid binding site in the important human transport protein serum albumin (HSA) is identified and characterized using an NBD (7 nitrobenz-2-oxa-1,3-diazol-4-yl)-C12 fatty acid. This ligand exhibits a 1:1 binding stoichiometry in its HSA complex with high site-specificity. The complex dissociation constant is determined by titration experiments as well as radioactive equilibrium dialysis. Competition experiments with the known HSA binding drugs warfarin and ibuprofen confirm the new binding site to be different from Sudlow-sites I and II. These binding studies are extended to other albumin binders and fatty acid derivatives. Furthermore an X-ray crystal structure allows locating the binding site in HSA subdomain IIA. The knowledge about this novel HSA site will be important for drug depot development and for understanding drug protein interaction, which are important prerequisites for modulation of drug pharmacokinetics. PMID- 29193546 TI - Relationship between high-risk patients receiving prescription opioids and high volume opioid prescribers. AB - AIMS: (1) To characterize the amount of prescription opioids prescribed for high risk patients by low-volume prescribers; (2) to quantify how high- and low-volume prescribers differ systematically in their prescribing patterns. DESIGN: Cross sectional study using 2015 longitudinal, all-payer QuintilesIMS pharmacy claims. We conducted an aggregated analysis for the first aim and an individual-level analysis for the second aim. SETTING: California, Florida, Georgia, Maryland, and Washington, USA. PARTICIPANTS: Among 4 046 275 patients, we identified 375 848 concomitant users (filling more than 30-days of concomitant opioids and benzodiazepines), 150 814 chronic users (using 100+ morphine milligram equivalents (MMEs) per day for more than 90 days), and 3190 patients prescribed opioids by > 3 prescribers and filling opioids at > 3 pharmacies during any 90 day period. Among 192 126 prescribers, we identified 8023 high-volume prescribers, who comprised the highest fifth percentile of opioid volume during four calendar quarters. MEASUREMENTS: (1) MME dose per transaction, (2) days supplied per transaction, (3) total opioid volume per patient and (4) number of prescriptions per patient. We also examined differences in opioid dispensing between high- and low-volume prescribers among patients receiving opioids from both. FINDINGS: Low-volume prescribers accounted for 15-29% of opioid volume and 18-56% of opioid prescriptions for high-risk patients, compared with 28-37% and 53-58% for low-risk patients. After accounting for state of residence, comorbid burden, prescriber specialty and care sequence, patients were more likely to receive higher doses (60.9 versus 53.2 MMEs per day, P < 0.01), longer supplies (22.1 versus 15.6 days, P < 0.01), more prescriptions (4.0 versus 2.6 prescriptions, P < 0.01) and greater opioid volume (5.6 versus 1.9 g, P < 0.01) from high- than low-volume prescribers. CONCLUSIONS: In the United States, high risk patients obtain a substantial proportion of prescription opioids from low volume prescribers. The differences in prescribing patterns between high- and low volume prescribers suggest the importance of interventions targeting prescriber behaviors. PMID- 29193547 TI - Safety and efficacy of telbivudine in late pregnancy to prevent mother-to-child transmission of hepatitis B virus: A multicenter prospective cohort study. AB - Infection of hepatitis B virus (HBV) occurs in ~10% of infants of HBV-infected mothers with positive hepatitis B e antigen (HBeAg) after immunoprophylaxis. We aimed to evaluate the safety and efficacy of telbivudine used during late pregnancy for preventing mother-to-child transmission of HBV. We conducted a multicenter prospective cohort study in 5 hospitals from 2012 to 2014, which enrolled HBV-infected singleton pregnant women with positive HBeAg. By their choice, women were divided into therapy (telbivudine 600 mg/day, from gestation 28-32 weeks to 3-4 weeks postpartum) and control (no antiviral agent) groups. Infants received passive-active immunoprophylaxis and follow-up at the age of 7 14 months. Totally, 328 pregnant women were included: 149 in the telbivudine group and 179 in the control group. Baseline HBV DNA levels were similar in the 2 groups (7.43 vs 7.37 log10 IU/mL, P = .711). At delivery, HBV DNA levels in the telbivudine and control groups were 3.80 and 7.26 log10 IU/mL, respectively (P < .0001). Of the infants, 128 (85.9%) in the telbivudine group and 156 (87.2%) in the control group were followed up. No infant in the telbivudine group had chronic infection, while 2 (1.28%) infants in the control group did (P = .503). Three (2.34%) infants in the telbivudine group, but none in the control group, had severe congenital or developmental abnormalities (P = .090). The data indicate that telbivudine may block perinatal HBV transmission. However, larger studies are required to clarify whether anti-HBV therapy in pregnancy is associated with severe adverse effects in the foetuses and infants. PMID- 29193548 TI - RePHILL: protocol for a randomised controlled trial of pre-hospital blood product resuscitation for trauma. AB - OBJECTIVES: To describe the 'Resuscitation with Pre-HospItaL bLood products' trial (RePHILL) - a multi-centre randomised controlled trial of pre-hospital blood product (PHBP) administration vs standard care for traumatic haemorrhage. BACKGROUND: PHBP are increasingly used for pre-hospital trauma resuscitation despite a lack of robust evidence demonstrating superiority over crystalloids. Provision of PHBP carries additional logistical and regulatory implications, and requires a sustainable supply of universal blood components. METHODS: RePHILL is a multi-centre, two-arm, parallel group, open-label, phase III randomised controlled trial currently underway in the UK. Patients attended by a pre hospital emergency medical team, with traumatic injury and hypotension (systolic blood pressure <90 mmHg or absent radial pulse) believed to be due to traumatic haemorrhage are eligible. Exclusion criteria include age <16 years, blood product receipt on scene prior to randomisation, Advanced Medical Directive forbidding blood product administration, pregnancy, isolated head injury and prisoners. A total of 490 patients will be recruited in a 1 : 1 ratio to receive either the intervention (up to two units of red blood cells and two units of lyophilised plasma) or the control (up to four boluses of 250 mL 0.9% saline). The primary outcome measure is a composite of failure to achieve lactate clearance of >=20%/h over the first 2 hours after randomisation and all-cause mortality between recruitment and discharge from the primary receiving facility to non-acute care. Secondary outcomes include pre-hospital time, coagulation indices, in-hospital transfusion requirements and morbidity. RESULTS: Pilot study recruitment began in December 2016. Approval to proceed to the main trial was received in June 2017. Recruitment is expected to continue until 2020. CONCLUSIONS: RePHILL will provide high-quality evidence regarding the efficacy and safety of PHBP resuscitation for trauma.

AB - We estimated the total number of undiagnosed HBV and HCV carriers and patients with hepatitis virus-related disease in Japan according to 6 different groups classified by their natural histories during 2011. In 2011, the total number of carriers and patients infected with HBV or HCV was estimated according to 6 groups using government reports and reports from the hepatitis epidemiology research group of The Ministry of Health, Labor and Welfare in Japan. In 2011, the total number of hepatitis virus carriers was estimated to be 2 090 128-2 840 128 in which the estimated number of undiagnosed HCV and HBV carriers was 776 826 (HBV: 481 470; HCV: 295 356). The total number of treated patients, as either inpatients or outpatients, was estimated to be 811588 (HBV: 303 366; HCV: 520 600) in 2011. It is presumed that many carriers shirk consultation for many reasons, such as patients' misunderstanding, lack of awareness and forgetfulness of their positive status. The numbers of infected patients who did not seek treatment increased gradually to 501 714-1 251 714 (HBV: 333 791-483 791; HCV: 167 923-767 923) in 2011. Compared to 2000, the number of undiagnosed carriers was significantly reduced in 2011 probably because of the well-organized, effective national hepatitis virus screening system that has been launched by the Japanese government since 2002. Moreover, the increase in the number of untreated persons who are aware of their positive status shows that more effort should be invested in improving the referral system from screening centres to core hospitals.

AB - Life history adaptations and spatial configuration of metapopulation networks allow certain species to persist in extreme fluctuating environments, yet long term stability within these systems relies on the maintenance of linkage habitat. Degradation of such linkages in urban riverscapes can disrupt this dynamic in aquatic species, leading to increased extinction debt in local populations experiencing environment-related demographic flux. We used microsatellites and mtDNA to examine the effects of collapsed network structure in the endemic Santa Ana sucker Catostomus santaanae of southern California, a threatened species affected by natural flood-drought cycles, "boom-and-bust" demography, hybridization and presumed artificial transplantation. Our results show a predominance of drift-mediated processes in shaping population structure and that reverse mechanisms for counterbalancing the genetic effects of these phenomena have dissipated with the collapse of dendritic connectivity. We use approximate Bayesian models to support two cases of artificial transplantation and provide evidence that one of the invaded systems better represents the historic processes that maintained genetic variation within watersheds than any remaining drainages where C. santaanae is considered native. We further show that a stable dry gap in the northern range is preventing genetic dilution of pure C. santaanae persisting upstream of a hybrid assemblage involving a non-native sucker and that local accumulation of genetic variation in the same drainage is influenced by position within the network. This work has important implications for declining species that have historically relied on dendritic metapopulation networks to maintain source-sink dynamics in phasic environments, but no longer possess this capacity in urban-converted landscapes.

AB - The development of bioorthogonal approaches for labeling of endogenous proteins under the multimolecular crowding conditions of live cells is highly desirable for the analysis and engineering of proteins without using genetic manipulation. N-Sulfonyl pyridone (SP) is reported as a new reactive group for protein sulfonylation. The ligand-directed SP chemistry was able to modify not only purified proteins in vitro, but also endogenous ones on the surface of and inside live cells selectively and rapidly, which allowed to convert endogenous proteins to FRET-based biosensors in situ. PMID- 29193551 TI - The microbial community of a biofilm contact reactor for the treatment of winery wastewater. AB - AIMS: To utilize a three-tiered approach to provide insight into the microbial community structure, the spatial distribution and the metabolic capabilities of organisms of a biofilm in the two towers of a high-rate biological contact reactor treating winery wastewater. METHODS AND RESULTS: Next-generation sequencing indicated that bacteria primarily responsible for the removal of carbohydrates, sugars and alcohol were more abundant in tower 1 than tower 2 while nitrifying and denitrifying bacteria were more abundant in tower 2. Yeast populations differed in each tower. Fluorescent in situ hybridization coupled with confocal microscopy showed distribution of organisms confirming an oxygen gradient across the biofilm depth. The Biolog system (ECO plates) specified the different carbon-metabolizing profiles of the two biofilms. CONCLUSIONS: The three-tiered approach confirmed that the addition of a second subunit to the bioreactor, expanded the treatment capacity by augmenting the microbial and metabolic diversity of the system, improving the treatment scope of the system. SIGNIFICANCE AND IMPACT OF THE STUDY: A three-tiered biofilm analysis provided data required to optimize the design of a bioreactor to provide favourable conditions for the development of a microbial consortium, which has optimal waste removal properties for the treatment requirements at hand. PMID- 29193553 TI - Styling without shedding: Novel topical formula reduces hair shedding by contracting the arrector pili muscle. AB - Approximately 40% of women experience excessive hair shedding during styling (e.g., hair brushing). Previously, we demonstrated that topically applied phenylephrine, a potent alpha1 adrenergic receptor agonist, can be used to contract the arrector pili muscle of the follicular unit; thus, increasing the force required to pluck hair and reducing shedding during brushing. While demonstrating efficacy, phenylephrine has several drawbacks when applied to the scalp, including the possibility cardiovascular events. We hypothesized that a high concentration of a weak alpha1 agonist would allow for: (a) rapid penetration through the stratum corneum eliciting a quick response; (b) a low probability of cardiac adverse events owing to the low receptor binding affinity; and (c) an efficacy of the weak alpha1 agonist similar to that of phenylephrine at the local site of application. Accordingly, we developed a novel topical solution, AB-102, containing a high concentration of a weak alpha1 agonist. Several studies were conducted to test the safety and efficacy of AB-102. In a dose escalating safety study, utilizing a wearable holter monitor, we observed no cardiac or hemodynamic adverse events. In addition, in a controlled efficacy study, AB-102 reduced the number of hairs shed during brushing by up to 77% (average of 38%). PMID- 29193554 TI - Do delays in data availability limit the implementation of near real-time vaccine safety surveillance using the Clinical Practice Research Datalink? AB - PURPOSE: Near real-time vaccine safety surveillance (NRTVSS) using electronic health records has been used to detect timely vaccine safety signals. Trial implementation of NRTVSS using the Clinical Practice Research Datalink (CPRD) has shown that there is limited power to detect safety signals for rare events. Delays in recording outcomes and receiving data influence the power and timeliness to identify a signal. Our work aimed to compare how different sources of delays influence power and expected time to signal to implement NRTVSS using CPRD. METHODS: We studied seasonal influenza vaccine/Guillain-Barre syndrome and performed power and expected time to signal calculations for the 2013-2014/2014 2015 seasons. We used the Poisson-based maximised sequential probability ratio test, which compares observed-to-expected events. For each study season, we obtained an average Guillain-Barre syndrome/seizures age-sex-adjusted rate from the 5 previous seasons and then used this rate to calculate the expected number of events, assuming a 42-day risk-window. Calculations were performed for detecting rate ratios of 1.5 to 10. We compared power and timeliness considering combinations of the presence/absence of delays in recording outcomes and in receiving data. The R-package Sequential was used. RESULTS: In general, there was >=80% power to detect increases in risk of >=4 at the end of the season. Assuming absence of delays slightly improved power (a maximum increase of 4%) but did not noticeably reduce time to detect a signal. CONCLUSION: Removing delays in data availability is insufficient to significantly improve the performance of a NRTVSS system using CPRD. Expansion of CPRD data is required. KEY POINTS The Clinical Practice Research Datalink (CPRD) can be used to implement near real-time vaccine safety surveillance, but there is limited power to detect signals for rare outcomes. Delays in recording outcomes and in receiving data might limit power and timeliness of a system. We assessed the influence of these sources of delays to inform data providers of the steps required to improve a system using CPRD data. Removing delays in recording outcomes and receiving data is unlikely to significantly improve the performance of a system using CPRD data. Expansion of the data available is needed. PMID- 29193555 TI - Overtreatment of older patients with type 2 diabetes mellitus in primary care. AB - Given that there are indications of overtreatment in older patients with type 2 diabetes in both the United States and Europe, we assessed the level of personalized diabetes treatment for older patients in primary care, focusing on overtreatment. Based on Dutch guidelines individuals aged >=70 years were classified into 3 glycated haemoglobin (HbA1c) treatment target groups: 7% (53 mmol/mol), 7.5% (58 mmol/mol) and 8% (64 mmol/mol). In our cohort of 1002 patients (n = 319 aged >=70 years), the 165 patients with HbA1c targets >7% had more micro- and macrovascular complications, more often used >=5 medicines and were more often frail compared with those with an HbA1c target <=7%. Of these 165 patients, 64 (38.8%) were overtreated; that is, 20% of all people aged >=70 years. The majority of overtreated people were frail and used >=5 medicines. Hypoglycaemia occurred in 20.3% of these patients and almost 30% reported accidents involving falls. Personalized treatment in older people with type 2 diabetes is not common practice. A substantial number of older people are overtreated, with probable harmful consequences. To prevent overtreatment, definition of lower HbA1c limits might be helpful. PMID- 29193556 TI - The Role of Copper Speciation in the Low Temperature Oxidative Upgrading of Short Chain Alkanes over Cu/ZSM-5 Catalysts. AB - Partial oxidative upgrading of C1 -C3 alkanes over Cu/ZSM-5 catalysts prepared by chemical vapour impregnation (CVI) has been studied. The undoped ZSM-5 support is itself able to catalyse selective oxidations, for example, methane to methanol, using mild reaction conditions and the green oxidant H2 O2 . Addition of Cu suppresses secondary oxidation reactions, affording methanol selectivities of up to 97 %. Characterisation studies attribute this ability to population of specific Cu sites below the level of total exchange (Cu/Al<0.5). These species also show activity for radical-based methane oxidation, with productivities exceeding those of the parent zeolite supports. When tested for ethane and propane oxidation reactions, comparable trends are observed. PMID- 29193557 TI - A three-goal model for patients with multimorbidity: A qualitative approach. AB - BACKGROUND: To meet the challenge of multimorbidity in decision making, a switch from a disease-oriented to a goal-oriented approach could be beneficial for patients and clinicians. More insight about the concept and the implementation of this approach in clinical practice is needed. OBJECTIVE: This study aimed to develop conceptual descriptions of goal-oriented care by examining the perspectives of general practitioners (GPs) and clinical geriatricians (CGs), and how the concept relates to collaborative communication and shared decision making with elderly patients with multimorbidity. METHOD: Qualitative interviews with GPs and CGs were conducted and analyzed using thematic analysis. RESULTS: Clinicians distinguished disease- or symptom-specific goals, functional goals and a new type of goals, which we labelled as fundamental goals. "Fundamental goals" are goals specifying patient's priorities in life, related to their values and core relationships. These fundamental goals can be considered implicitly or explicitly in decision making or can be ignored. Reasons to explicate goals are the potential mismatch between medical standards and patient preferences and the need to know individual patient values in case of multimorbidity, including the management in acute situations. CONCLUSION: Based on the perspectives of clinicians, we expanded the concept of goal-oriented care by identifying a three level goal hierarchy. This model could facilitate collaborative goal-setting for patients with multiple long-term conditions in clinical practice. Future research is needed to refine and validate this model and to provide specific guidance for medical training and practice. PMID- 29193558 TI - Short dental implants as compared to maxillary sinus augmentation procedure for the rehabilitation of edentulous posterior maxilla: Three-year results of a randomized clinical study. AB - BACKGROUND: Several treatment options exist for the implant-supported rehabilitation of edentulous posterior maxilla. PURPOSE: To compare maxillary sinus floor augmentation associated to standard length implants, with direct placement of implants of reduced length in the available residual bone. MATERIALS AND METHODS: Patients with edentulous posterior maxilla and a residual height of 4-7 mm were randomly allocated to the test (short implants [SIs], 6.5 to 8.5mm long) or the control (sinus augmentation [SA] and implants >=10mm long) group. Anorganic bovine bone was the grafting material for the control group. In both groups pure platelet-rich plasma was used to bioactivate implant surface prior to insertion. Implant and prosthesis survival, clinical variables, radiographic bone level change, quality of life, and patient satisfaction were assessed. RESULTS: Twenty-five patients were treated in the control group (58 standard length implants) and 27 in the test group (42 SIs). After 3 years of follow-up no implant failure and biological or mechanical complications were recorded. Marginal bone loss, soft tissue, and oral hygiene parameters were similar in the 2 groups at both 1 and 3 years' follow-up. Postoperative pain, swelling and other symptoms and daily activities were better in the SIs group than in the SA group, while patients' satisfaction after 1 year was similar. CONCLUSIONS: In spite of comparable medium-term clinical and radiographic outcomes, when the residual ridge height is sufficient for a safe placement, SIs may be preferred due to simplified protocol, less invasiveness, shorter treatment time, and reduced postoperative discomfort as compared to SA. PMID- 29193559 TI - Evaluation of exome filtering techniques for the analysis of clinically relevant genes. AB - A significant challenge facing clinical translation of exome sequencing is meaningful and efficient variant interpretation. Each exome contains ~500 rare coding variants; laboratories must systematically and efficiently identify which variant(s) contribute to the patient's phenotype. In silico filtering is an approach that reduces analysis time while decreasing the chances of incidental findings. We retrospectively assessed 55 solved exomes using available datasets as in silico filters: Online Mendelian Inheritance in Man (OMIM), Orphanet, Human Phenotype Ontology (HPO), and Radboudumc University Medical Center curated panels. We found that personalized panels produced using HPO terms for each patient had the highest success rate (100%), while producing considerably less variants to assess. HPO panels also captured multiple diagnoses in the same individual. We conclude that custom HPO-derived panels are an efficient and effective way to identify clinically relevant exome variants.

AB - We report the first catalytic diborylation of 1,1-disubstituted vinylarenes with pinacolborane using a cobalt catalyst generated from bench-stable Co(acac)2 and xantphos. A wide range of 1,1-disubstituted vinylarenes underwent this transformation to produce the corresponding gem-bis(boryl)alkanes in modest to high yields. This cobalt-catalyzed reaction can be readily conducted on a gram scale without the use of a dry box and represents a practical and effective approach to prepare a wide range of branched gem-bis(boryl)alkanes. PMID- 29193561 TI - Effectiveness and tolerability of therapy with exenatide once weekly vs basal insulin among injectable-drug-naive elderly or renal impaired patients with type 2 diabetes in the United States. AB - AIM: To evaluate the effectiveness and tolerability of exenatide once weekly (EQW) compared with basal insulin (BI) among injectable-drug-naive patients with type 2 diabetes mellitus (T2DM) who are elderly or have renal impairment (RI). MATERIALS AND METHODS: Initiators of EQW and BI with T2DM were identified for the period 2012 to 2015 within a US electronic health record database and matched by propensity score. Matched EQW and BI initiators aged >=65 years or who had RI were compared. Data on weight, glycated haemoglobin (HbA1c), estimated glomerular filtration rate (eGFR), blood pressure and lipids were obtained at baseline and quarterly (Q1-Q4) or semi-annually for 1 year after drug initiation. Hypoglycaemia and gastrointestinal symptoms were identified using diagnosis codes and data abstracted from clinical notes. RESULTS: Among patients aged >=65 years, HbA1c changed by -0.50 and -0.31 percentage points from baseline to Q4 for EQW and BI initiators, respectively. Weight changed by -1.6 kg among EQW initiators compared with 0.2 kg among BI initiators. Compared with BI initiators, EQW initiators had a 1.45-fold increased risk of nausea and vomiting. Among patients with RI, HbA1c changed by -0.58 and -0.33 percentage points from baseline to Q4 for EQW and BI initiators, respectively. Weight changed by -1.9 kg for EQW initiators while BI initiators had no change in weight. EQW initiators had a 1.28 fold increased risk of constipation and diarrhoea compared with BI initiators. CONCLUSION: Regardless of age or renal function, the benefits of EQW relative to BI treatment are improved glycaemic control and increased weight loss, which should be weighed against the increased risk of gastrointestinal symptoms. PMID- 29193562 TI - Resveratrol-induced thrombocytopenia: Inadvertent side-effect of a commonly used antioxidant. PMID- 29193563 TI - Sacubitril/valsartan reduces serum uric acid concentration, an independent predictor of adverse outcomes in PARADIGM-HF. AB - AIMS: Elevated serum uric acid concentration (SUA) has been associated with an increased risk of cardiovascular disease, but this may be due to unmeasured confounders. We examined the association between SUA and outcomes as well as the effect of sacubitril/valsartan on SUA in patients with heart failure with reduced ejection fraction (HFrEF) in PARADIGM-HF. METHODS AND RESULTS: The association between SUA and the primary composite outcome of cardiovascular death or heart failure (HF) hospitalization, its components, and all-cause mortality was examined using Cox regression analyses among 8213 patients using quintiles (Q1 Q5) of SUA adjusted for baseline prognostic variables including estimated glomerular filtration rate (eGFR), diuretic dose, and log N-terminal pro-brain natriuretic peptide. Change in SUA from baseline over 12 months was also evaluated in each treatment group. Patients in Q5 (SUA >=8.6 mg/dL) compared with Q1 (<5.4 mg/dL) were younger (62.8 vs. 64.2 years), more often male (88.7% vs. 63.1%), had lower systolic blood pressure (119 vs. 123 mmHg), lower eGFR (57.4 vs. 76.6 mL/min/1.73 m2 ), and greater diuretic use. Higher SUA was associated with a higher risk of the primary outcome (adjusted hazard ratios) Q5 vs. Q1 = 1.28 [95% confidence intervals (1.09-1.50), P = 0.003], cardiovascular death [1.44 (1.11-1.77), P = 0.001], HF hospitalization [1.37 (1.11-1.70), P = 0.004], and all-cause mortality [1.36 (1.13-1.64), P = 0.001]. Compared with enalapril, sacubitril/valsartan reduced SUA by 0.24 (0.17-0.32) mg/dL over 12 months (P < 0.0001). Sacubitril/valsartan improved outcomes, irrespective of SUA concentration. CONCLUSION: Serum uric acid concentration was an independent predictor of worse outcomes after multivariable adjustment in patients with HFrEF. Compared with enalapril, sacubitril/valsartan reduced SUA and improved outcomes irrespective of SUA. PMID- 29193564 TI - IFN-free therapy is associated with restoration of type I IFN response in HIV-1 patients with acute HCV infection who achieve SVR. AB - Interferon (IFN)-free direct-acting antiviral agents (DAAs) have revolutionized chronic hepatitis C virus (HCV) treatment; early studies suggest excellent efficacy in acute HCV. However, changes in innate immune responses during DAA therapy for acute HCV are unknown. We studied interferon-stimulated gene (ISG) expression and related cytokines/chemokines in HIV-infected patients with acute HCV receiving sofosbuvir plus ribavirin (SOF+RBV) as part of the A5327 clinical trial. ISG expression was determined from PBMCs, and circulating cytokines/chemokines were quantified from serum from study participants. The overall sustained virologic response (SVR) was 57%; all treatment failures were due to virologic relapse. Apart from NOS2a, baseline ISG/chemokine/cytokine levels were similar irrespective of treatment outcome. Downregulation of ISGs was observed at treatment week four and end of treatment (EOT), implicating HCV in establishing elevated ISGs early during HCV infection. Levels of many of these ISGs increased at post-treatment week 12 (PTW12) in relapsers only, coinciding with recurrent HCV RNA. Eleven ISGs were differentially expressed in responders vs relapsers. On-treatment viral suppression was also associated with a reduction in IP-10, CXCL11 and MIP-1beta levels. In contrast, circulating IFN-alpha levels were significantly higher at EOT and PTW12 in responders vs relapsers. Upregulation of peripheral ISG expression is established early in the course of HCV infection during acute HCV infection, but did not predict subsequent treatment outcome with SOF+RBV. ISGs were downregulated during therapy and increased post-therapy in relapsers. IFN-alpha levels were higher in responders at EOT/PTW12, suggesting that impaired type I IFN production/secretion may contribute to relapse.

PMID- 29193566 TI - Systematic review and meta-analysis of algorithms used to identify drug-induced liver injury (DILI) in health record databases. AB - BACKGROUND & AIMS: Drug induced liver injury (DILI) is largely underreported, leading to underestimation of its burden. Electronic detection of DILI in healthcare databases shows promise to overcome the issues of spontaneous reporting. The performance of detection algorithms may vary because of inconsistent DILI definition and detection criteria. We performed a systematic review and meta-analysis to identify the DILI detection criteria used in health record databases and determine the performance characteristics of the detection algorithms. METHODS: We searched PubMed, EMBASE and Scopus for studies that utilized laboratory threshold criteria to identify DILI cases. Validation studies were included in the meta-analysis. Data were abstracted using standardized forms and quality was assessed using modified Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) criteria. We evaluate the performance characteristics of the detection algorithm by obtaining the pooled estimate of the positive predictive value (PPV) assuming a random effects model. RESULTS: A total of 29 studies met the inclusion criteria for the systematic review; 25 of these studies (n = 35 948) had PPV estimates for performing the meta-analysis. The PPV of DILI detection algorithms was low, ranging from 1.0% to 40.2%, with a pooled estimate of 14.6% (95% CI 10.7-18.9). Algorithms that performed better had prespecified exclusion diagnoses as well as drugs of interest to minimize false positives. CONCLUSION: Algorithm performance varied with different case definitions of DILI attributed to different laboratory threshold criteria, diagnosis codes, and study drugs.

PMID- 29193568 TI - Language barriers and their impact on provision of care to patients with limited English proficiency: Nurses' perspectives. AB - AIM AND OBJECTIVE: To explore nurses' perspectives of language barriers and their impact on the provision of care to patients with limited English proficiency from diverse linguistic background. DESIGN AND METHODS: A qualitative descriptive approach was used. Using individual interviews and focus group discussions, data were collected from 59 nurses working in tertiary care hospitals in England. A thematic analysis was used to analyse the data. FINDINGS: Three themes, "multi ethnicities and language barriers," "the impact of language barriers" and "communicating via interpreters," were identified. Communication was identified as the most important aspect of care provision and an essential component of a nurse's professional role regardless of the clinical area or speciality. Language barriers were identified as the biggest obstacles in providing adequate, appropriate, effective and timely care to patients with limited English proficiency. Use of professional interpreters was considered useful; however, the limitations associated with use of interpretation service, including arrangement difficulties, availability and accessibility of interpreters, convenience, confidentiality and privacy-related issues and impact on the patient's comfort were mentioned. CONCLUSIONS: Language barriers, in any country or setting, can negatively affect nurses' ability to communicate effectively with their patients and thereby have a negative impact on the provision of appropriate, timely, safe and effective care to meet patient's needs. RELEVANCE TO CLINICAL PRACTICE: An understanding of language barriers can help nurses find appropriate strategies to overcome such barriers and, consequently, enhance the provision of effective care to patients affected by language barriers in any clinical setting in any healthcare system. The findings of the study have international relevance as language barriers affect healthcare provision in any country or setting. PMID- 29193569 TI - 9.4T and 17.6T MRI of Retinoblastoma: Ex Vivo evaluation of microstructural anatomy and disease extent compared with histopathology. AB - BACKGROUND: Retinoblastoma is the most common intraocular tumor in childhood with a good prognosis in terms of mortality, but detailed information about tumor morphology and disease extent in retinoblastoma is important for treatment decision making. PURPOSE: To demonstrate ultrahigh-field MRI tumor morphology and tumor extent in retinoblastoma correlating with in and ex vivo images with histopathology. STUDY TYPE: Prospective case series. POPULATION: Six retinoblastoma patients (median age 5.5 months, range 2-14) were prospectively included in this study. Median time between diagnosis and enucleation was 8 days (range 7-19). FIELD STRENGTH/SEQUENCE: In vivo pre-enucleation at 1.5T MRI with a circular surface coil. Ex vivo imaging (FLASH T1 -weighted and RARE T2 -weighted) was performed at field strengths of 9.4T and 17.6T. ASSESSMENT: After ex vivo imaging, the eyes were histopathologically analyzed and morphologically matched with MRI findings by three authors (two with respectively 14 and 4 years of experience in ocular MRI and one with 16 years of experience in ophthalmopathology). RESULTS: Small submillimeter morphological aspects of intraocular retinoblastoma were successfully depicted with higher-resolution MRI and matched with histopathology images. With ex vivo MRI a small subretinal tumor seed (300 MUm) adjacent to the choroid was morphologically matched with histopathology. Also, a characteristic geographical pattern of vital tumor tissue (400 MUm) surrounding a central vessel interspersed with necrotic areas correlated with histopathology images. Tumor invasion into the optic nerve showed a higher signal intensity on T1 -weighted higher-resolution MRI. DATA CONCLUSION: Higher-resolution MRI allows for small morphological aspects of intraocular retinoblastoma and extraocular disease extent not visible on currently used clinical in vivo MRI to be depicted.

PMID- 29193570 TI - CO Hydrogenation on Cobalt-Based Catalysts: Tin Poisoning Unravels CO in Hollow Sites as a Main Surface Intermediate. AB - Site poisoning is a powerful method to unravel the nature of active sites or reaction intermediates. The nature of the intermediates involved in the hydrogenation of CO was unraveled by poisoning alumina-supported cobalt catalysts with various concentrations of tin. The rate of formation of the main reaction products (methane and propylene) was found to be proportional to the concentration of multi-bonded CO, likely located in hollow sites. The specific rate of decomposition of these species was sufficient to account for the formation of the main products. These hollow-CO are proposed to be main reaction intermediates in the hydrogenation of CO under the reaction conditions used here, while linear CO are mostly spectators.

PMID- 29193572 TI - Incretin-based therapies and risk of pancreatic cancer in patients with type 2 diabetes: A meta-analysis of randomized controlled trials. AB - AIMS: To perform a meta-analysis of randomized controlled trials (RCTs), including 6 recently published large-scale cardiovascular outcome trials (CVOTs), to evaluate the risk of pancreatic cancer with incretin-based therapies in patients with type 2 diabetes (T2DM). MATERIALS AND METHODS: For the period January 1, 2007 to May 1, 2017, the PubMed, Embase, Cochrane Central Register and ClininalTrials.gov databases were searched for RCTs in people with T2DM that compared incretin drugs with placebo or other antidiabetic drugs, with treatment and follow-up durations of >=52 weeks. Two reviewers screened the studies, extracted the data and assessed the risk of bias independently and in duplicate. RESULTS: A total of 33 studies (n = 79 971), including the 6 CVOTs, with 87 pancreatic cancer events were identified. Overall, the pancreatic cancer risk was not increased in patients administered incretin drugs compared with controls (Peto odds ratio [OR] 0.67, 95% confidence interval [CI] 0.44-1.02). In the 6 CVOTs, 79 pancreatic cancer events were identified in 55 248 participants. Pooled estimates of the 6 CVOTs showed an identical tendency (Peto OR 0.65, 95% CI 0.42 1.01). Notably, in the subgroup of participants who received treatment and follow up for >=104 weeks, 84 pancreatic cancer events were identified in 59 919 participants, and a lower risk of pancreatic cancer was associated with incretin based therapies (Peto OR 0.62, 95% CI 0.41-0.95). CONCLUSIONS: Treatment with incretin drugs was not associated with an increased risk of pancreatic cancer in people with T2DM. Instead, it might protect against pancreatic malignancy in patients treated for >=104 weeks. PMID- 29193573 TI - Great and rapid HBsAg decline in patients with on-treatment hepatitis flare in early phase of potent antiviral therapy. AB - HBsAg decline during nucleos(t)ide analogue therapy in chronic hepatitis B with lower pretherapy ALT is usually small and slow. This study aimed to investigate why ~10% of such patients showed "rapid HBsAg decline" >=0.5 log10 IU/mL by month 6 of therapy. Patients with persistent pretherapy ALT <5X ULN who had qHBsAg at baseline, months 6 and 12 of entecavir or tenofovir therapy were studied. "On treatment ALT elevation" was defined as >10% increase above baseline to >2X ULN during first 6 months of therapy. Of the 256 patients treated, 51 experienced transient "on-treatment ALT elevation" [group A], including 30 (11.7%) with ALT elevation to 2-5X ULN [group A-1] and 21 (8.2%) flared to >5X ULN [group A-2]. The magnitude of qHBsAg decline and rate of "rapid HBsAg decline" by month 6 was significantly greater and more frequent in group A (-0.446 vs -0.042 log10 IU/mL; 45.1 vs 8.8%, respectively, P = 0.000) than in the remaining 205 patients without on-treatment ALT elevation (group B), being greatest in patients with hepatitis flare (group A-2: -0.559 log10 IU/mL and 57.1%, respectively). In patients with therapy >=2 years, patients with "on-treatment ALT elevation" also showed significantly greater annual HBsAg decline, more frequent to <100 IU/mL and 4 times higher HBsAg seroclearance rate. "On-treatment ALT elevation," especially flare >5X ULN, during entecavir therapy or tenofovir therapy may enhance/accelerate HBsAg decline, suggesting the effect of immune restoration upon potent viral suppression. PMID- 29193574 TI - Norcantharidin induce apoptosis in human nasopharyngeal carcinoma through caspase and mitochondrial pathway. AB - While Nasopharyngeal carcinoma (NPC) is uncommon in western countries, it is endemic in Southeast Asia and Southern China. Previous study of norcantharidin (NCTD), isolated from blister beetles, has proved its anticancer effect on various tumors. However, the effect of NCTD in NPC has never been studied. The purpose of this study is to inspect the suppression activity of NCTD on NPC, along with the underlying mechanism. NPC cell line NPC-BM was treated with NCTD. NCTD remarkably inhibited proliferation and induce apoptosis in NPC-BM cell. Activation of caspase-3, -8, -9 was observed through western blotting. The expression of antiapoptotic protein Bcl-XL was significantly reduced, but expression of proapoptotic protein Bak was increased after treatment of NCTD. The cytotoxic effect of NCTD on NPC-BM cell is mainly due to apoptosis, mediated by caspase and mitochondrial pathway. These results suggested that NCTD could be a potential anticancer agent for NPC.

AB - BACKGROUND & AIMS: Chronic alcohol consumption and alcoholic liver disease (ALD) afflicts individuals with substantial morbidity and mortality with limited treatment options available. Hepatic inflammation, triggered by activated Kupffer cells, is a driving force in alcoholic liver disease. Interleukin 37 (IL-37) exerts anti-inflammatory effects in hepatic diseases, however, the impact of Interleukin 37 on alcoholic liver disease is unknown. In this study, we addressed the role of Interleukin 37 in alcoholic liver disease. METHODS: We utilized Interleukin 37 expressing transgenic mice and human recombinant Interleukin 37 in models of alcoholic liver disease. Interleukin 37 expression was measured in liver samples of 20 alcoholic steatohepatitis and 36 non-alcoholic fatty liver disease patients. RESULTS: Interleukin 37 transgenic mice are not protected against hepatic injury and inflammation in alcoholic liver disease. Ethanol suppressed Interleukin 37 expression in transgenic mice. Alcoholic steatohepatitis (ASH) patients similarly exhibited reduced Interleukin 37 expression when compared to non-alcoholic fatty liver disease (NAFLD) patients. Human recombinant Interleukin 37 ameliorated hepatic inflammation in a binge drinking model of alcoholic liver disease. CONCLUSION: We provide evidence for an exogenous noxae that suppresses Interleukin 37 expression which limits its anti inflammatory effects in alcoholic liver disease.

AB - AIMS: The SERVE-HF trial investigated the impact of treating central sleep apnoea (CSA) with adaptive servo-ventilation (ASV) in patients with systolic heart failure. A preplanned substudy was conducted to provide insight into mechanistic changes underlying the observed effects of ASV, including assessment of changes in left ventricular function, ventricular remodelling, and cardiac, renal and inflammatory biomarkers. METHODS AND RESULTS: In a subset of the 1325 randomised patients, echocardiography, cardiac magnetic resonance imaging (cMRI) and biomarker analysis were performed at baseline, and 3 and 12 months. In secondary analyses, data for patients with baseline and 12-month values were evaluated; 312 patients participated in the substudy. The primary endpoint, change in echocardiographically determined left ventricular ejection fraction from baseline to 12 months, did not differ significantly between the ASV and the control groups. There were also no significant between-group differences for changes in left ventricular dimensions, wall thickness, diastolic function or right ventricular dimensions and ejection fraction (echocardiography), and on cMRI (in small patient numbers). Plasma N-terminal pro B-type natriuretic peptide concentration decreased in both groups, and values were similar at 12 months. There were no significant between-group differences in changes in cardiac, renal and systemic inflammation biomarkers. CONCLUSION: In patients with systolic heart failure and CSA, addition of ASV to guideline-based medical management had no statistically significant effect on cardiac structure and function, or on cardiac biomarkers, renal function and systemic inflammation over 12 months. The increased cardiovascular mortality reported in SERVE-HF may not be related to adverse remodelling or worsening heart failure. PMID- 29193580 TI - Stomas: time for a closer look.

PMID- 29193585 TI - Unravelling the Carbohydrate-Binding Preferences of the Carbohydrate-Binding Modules of AMP-Activated Protein Kinase. AB - The beta subunit of adenosine monophosphate (AMP)-activated protein kinase (AMPK), which exists as two isoforms (beta1 and beta2) in humans, has a carbohydrate-binding module (CBM) that interacts with glycogen. Although the beta1- and beta2-CBMs are structurally similar, with strictly conserved ligand contact residues, they show different carbohydrate affinities. beta2-CBM shows the strongest affinity for both branched and unbranched oligosaccharides and it has recently been shown that a Thr insertion into beta2-CBM (Thr101) forms a pocket to accommodate branches. This insertion does not explain why beta2-CBM binds all carbohydrates with stronger affinity. Herein, it is shown that residue 134 (Val for beta2 and Thr for beta1), which does not come into contact with a carbohydrate, appears to account for the affinity difference. Characterisation by NMR spectroscopy, however, suggests that mutant beta2-Thr101Delta/Val134Thr differs from that of beta1-CBM, and mutant beta1-Thr101ins/Thr134Val differs from that of beta2-CBM. Furthermore, these mutants are less stable to chemical denaturation, relative to that of wild-type beta-CBMs, which confounds the affinity analyses. To support the importance of Thr101 and Val134, the ancestral CBM has been constructed. This CBM retains Thr101 and Val134, which suggests that the extant beta1-CBM has a modest loss of function in carbohydrate binding. Because the ancestor bound carbohydrate with equal affinity to that of beta2-CBM, it is concluded that residue 134 plays an indirect role in carbohydrate binding.

AB - CONTEXT: Preventing unintended pregnancy and HIV transmission is important for women with HIV, but little is known about their contraceptive use, particularly under current antiretroviral therapy (ART) recommendations for treatment and prevention. METHODS: The prevalence of contraceptive use and of dual protection was examined among 453 sexually active women with HIV aged 16-49 and enrolled in the Canadian HIV Women's Sexual and Reproductive Health Cohort Study in 2013 2015; multivariable logistic regression was used to identify correlates of use. Two definitions of dual protection were assessed: the World Health Organization (WHO) definition (consistent condom use alongside another effective method) and an expanded definition (consistent condom use or a suppressed HIV viral load alongside an effective method). RESULTS: Overall, 73% of women used effective contraceptives, primarily male condoms (45%) or tubal ligation (19%). Eighteen percent practiced WHO-defined dual protection, and 40% practiced dual protection according to the expanded definition. Characteristics positively associated with contraceptive use were younger age, having been pregnant, being heterosexual, being unaware of ART's HIV prevention benefits and having had partners of unknown HIV status (odds ratios, 1.1-6.7). Younger age and perceived inability to become pregnant were positively associated with both definitions of dual protection (1.04-3.3); additionally, WHO-defined dual protection was associated with perceiving HIV care to be women-centered and having had partners of unknown HIV status (2.0-4.1), and dual protection under the expanded definition was related to having been pregnant (2.7). CONCLUSIONS: Future research should explore how sustained ART and broader contraceptive options can support women's sexual and reproductive health care needs.

AB - Electrochemically reducing CO2 into fuels using renewable electricity is a contemporary global challenge that requires significant advances in catalyst design. Photodeposition techniques were used to screen ternary alloys of Cu-Zn Sn, which includes brass and bronze, for the electrocatalytic reduction of CO2 to CO and formate. This analysis identified Cu0.2 Zn0.4 Sn0.4 and Cu0.2 Sn0.8 to be capable of reaching Faradaic efficiencies of >80 % for CO and formate formation, respectively, and capable of achieving partial current densities of 3 mA cm-2 at an overpotential of merely 200 mV. PMID- 29193587 TI - Phlebotomy as a preventive measure for crocidolite-induced mesothelioma in male rats. AB - Malignant mesothelioma (MM) is a rare but socially important neoplasm due to its association with asbestos exposure. Malignant mesothelioma is difficult to diagnose at an early stage, yet there are no particularly effective treatments available at the advanced stage, thus necessitating efficient strategies to prevent MM in individuals already exposed to asbestos. We previously showed that persistent oxidative damage caused by foreign body reaction and affinity of asbestos both to hemoglobin and histones is one of the major pathogeneses. Accordingly, as an effective strategy to prevent asbestos-induced MM, we undertook the use of an iron chelator, deferasirox, which decreased the epithelial-mesenchymal transition in a crocidolite-induced rat MM model. However, this agent may show adverse effects. Here, we studied the effects of iron removal by phlebotomy as a realistic measure on the same rat model. We injected a total of 5 mg crocidolite i.p. to F1 hybrid rats between the Fischer-344 and Brown Norway strains at the age of 6 weeks. We repeated weekly or biweekly phlebotomy of 6-8 mL/kg/time from 10 to 60 weeks of age. The animals were observed until 120 weeks. In male rats, phlebotomy significantly decreased the weight and nuclear grade of MM, and modestly reduced the associated ascites and the fraction of more malignant sarcomatoid subtype. Weekly phlebotomy prolonged long-term survival. Our results indicate that appropriate phlebotomy may be a practical preventive measure to attenuate the initiation and promotion capacity of asbestos towards MM by reducing iron in individuals exposed to asbestos.

AB - BACKGROUND: Mentorship of junior faculty is an integral component of career development. The Children's Oncology Group (COG) Young Investigator (YI) Committee designed a mentorship program in 2004 whose purpose was to pair YIs (faculty <=10 years of first academic appointment) with a senior mentor to assist with career development and involvement in COG research activities. This study reports on the committee's ability to achieve these goals. PROCEDURE: An online survey was sent to YIs who were registered with the program from 2004 to2015, assessing three major domains: (1) overall experience with the mentor pairing, (2) satisfaction with the program, and (3) academic accomplishments of the mentees. RESULTS: The response rate was 64% (110/171). Overall, YIs rated the success of their mentorship pairing as 7.2 out of 10 (median) (25th, 75th quartile 3.6, 9.6). The direct effects of the mentorship program included 70% YIs reporting a positive effect on their career, 40% reporting any grant or manuscript resulting from the pairing, 47% forming a new research collaboration, and 43% receiving appointment to a COG committee. Respondents reported success in COG with 38% authoring a manuscript on behalf of COG and 65% reporting a leadership position including seven current or past COG discipline chairs and 20 study chairs. Finally, 74% of respondents said they would consider serving as mentors in the program in the future. CONCLUSION: The COG YI mentorship program has been well received by the majority of the participants and has helped to identify and train many current leaders in COG. PMID- 29193589 TI - Corrigendum.

AB - AIMS AND OBJECTIVES: To investigate the experiences of patients who received a medical emergency team review following a period of clinical deterioration and their views about the potential use of a patient and family activated escalation system. BACKGROUND: Delay or failure by health professionals to respond to clinical deterioration remains a patient safety concern. Patients may sometimes identify subtle cues of early deterioration prior to changes in vital signs. In response to health professional and system failures, patient and family activated escalation systems have been mandated and implemented in Australia. However, little research has evaluated their effectiveness nor taken patients' perspectives into account. DESIGN: Qualitative exploratory descriptive design was used. METHODS: Purposive sampling was used. Semistructured interviews were undertaken in 2014 with 33 patients who required medical emergency team intervention. Data were collected from one private and one public hospital in Melbourne, Victoria, Australia. The framework method was used to analyse the data. RESULTS: All patients stated that it was the clinician who detected and responded to deterioration. Private patient participants were unaware of the medical emergency team system, and felt escalating care was not their responsibility. These patients reported being too sick to communicate prior to and during medical emergency team review and did not favour a patient and family activated escalation system. Public patients were well informed about the medical emergency team system yet expressed concerns around overriding clinicians if activating a patient and family activated escalation system. CONCLUSION: Patient participation during a period of deterioration is restricted by their clinical condition and limited medical knowledge. Patients felt comfortable to communicate concerns to clinicians but felt they would not activate the patient and family activated escalation system. This behoves clinicians to actively listen and respond to patient concerns. RELEVANCE TO CLINICAL PRACTICE: Clinicians must promote a collaborative relationship and encourage patients to communicate their concerns. Given the perceived barriers to patient and family activated escalation systems use, resources being employed for their implementation could be redistributed to other areas of patient safety.

PMID- 29193593 TI - Concomitant nonalcoholic fatty liver disease does not alter the activity, severity or course of primary biliary cholangitis. AB - BACKGROUND & AIMS: The impact of nonalcoholic fatty liver disease (NAFLD) on the natural history of primary biliary cholangitis (PBC) has yet to be described. The aim of this study was to document the activity, severity and progression of PBC in patients with concomitant NAFLD and compare the findings to those with PBC alone. METHODS: Disease activity was assessed by serum liver enzyme levels; severity, by Fib-4 scores and percent of patients with APRI >1.5; and progression, by changes in Fib-4 and prevalence of APRI >1.5 during follow-up. RESULTS: The study populations consisted of 168 PBC alone and 68 PBC/NAFLD patients. The mean ages and gender distributions of the two cohorts were similar. At presentation, PBC alone patients had greater disease activity (higher serum ALP and GGT values, P = .003 and 0.01, respectively) and advanced disease (higher Fib-4 (P = .04) scores) than PBC/NAFLD patients. Although the prevalence of APRI >1.5 was also higher in PBC alone (11.1%) vs PBC/NAFLD (4.7%) patients, the difference was not significant (P = .16). During mean follow-up of 6.7 +/- 5.5 (PBC alone) and 6.4 +/- 4.4 (PBC/NAFLD) years (ranges: 0.5-21 years) annual increases in Fib-4 and prevalence of >= APRI 1.5 were greater in PBC alone patients but the differences did not reach statistical significance. CONCLUSIONS: The results of this retrospective, single centre study suggest that the activity, severity and progression of PBC are not adversely affected by concomitant NAFLD.

AB - The incidence of non dermatophytic mould (NDM) onychomycosis (OM) has been steadily increasing Fusarium spp is the most common cause of NDM OM in most geographical locations. Fusarium spp and other NDMs are largely resistant to commonly used anti-fungals. The successful use of laser and light based devices has been demonstrated in dermatophytic OM, but there is no previous report of their successful use in any NDM OM. We describe a patient with OM caused by Fusarium solani spp, who was clinically (with a normal appearing nail) and mycologically (with negative microscopy and culture on repeated samples) cured of her infection following treatment with 2 sessions of Qs NdYAG (532nm and 1064nm) given 1 month apart. PMID- 29193596 TI - Superiorly based facial artery musculomucosal flap: A versatile pedicled flap. AB - BACKGROUND: The superiorly based facial artery musculomucosal (FAMM) flap is pedicled on the angular artery. This flap offers a well-vascularized mucosal surface allowing closure of medium size defects, most frequently within the oral cavity and intranasal region. METHODS: We describe a superiorly based harvest of the FAMM flap, which may be used for closure of multiple head and neck surgical defects. An operative technique video is provided, which can be viewed online. RESULTS: Our results demonstrate a fast and relatively straightforward harvest technique of the FAMM flap. This intraoral flap is a useful reconstructive tool, which also has the advantage to leave no visible external scars. CONCLUSION: The superiorly pedicled FAMM flap is a versatile and effective technique that may be integrated in the algorithm for reconstruction of head and neck defects. PMID- 29193597 TI - Mycotic pseudoaneurysm of a pulmonary artery branch caused by Cladosporium. AB - We report the case of a 53-year-old male with a history of acute myelogenous leukemia, who suffered the rupturing of a right-sided pulmonary artery pseudoaneurysm combined with pneumonia. He underwent a right-sided lower lobectomy. The resected lung tissue demonstrated a mycotic pseudoaneurysm of a pulmonary artery branch together with a filamentous fungal infection. Pseudoaneurysms are caused by the breaching of all layers of a blood vessel wall. The extravasated blood is trapped by the surrounding extravascular tissue or clots. Cladosporium was detected during a polymerase chain reaction-based analysis followed by DNA sequencing of formalin-fixed paraffin-embedded lung tissue samples. Although previous cases of pulmonary artery pseudoaneurysms caused by fungal infections, e.g., Candida or Aspergillus sp., have been reported, to the best of our knowledge this is the first case to involve cladosporiosis. PMID- 29193598 TI - Pseudomonas fluorescens Strain R124 Encodes Three Different MIO Enzymes. AB - A number of class I lyase-like enzymes, including aromatic ammonia-lyases and aromatic 2,3-aminomutases, contain the electrophilic 3,5-dihydro-5-methylidene-4H imidazol-4-one (MIO) catalytic moiety. This study reveals that Pseudomonas fluorescens R124 strain isolated from a nutrient-limited cave encodes a histidine ammonia-lyase, a tyrosine/phenylalanine/histidine ammonia-lyase (XAL), and a phenylalanine 2,3-aminomutase (PAM), and demonstrates that an organism under nitrogen-limited conditions can develop novel nitrogen fixation and transformation pathways to enrich the possibility of nitrogen metabolism by gaining a PAM through horizontal gene transfer. The novel MIO enzymes are potential biocatalysts in the synthesis of enantiopure unnatural amino acids. The broad substrate acceptance and high thermal stability of PfXAL indicate that this enzyme is highly suitable for biocatalysis.

AB - The Hippo- yes-associated protein (YAP) pathway is essential for controlling organ size and tumorigenesis. Previous studies have demonstrated that the primary outcome of YAP signaling in the nucleus is achieved by interaction with the transcription factor TEA domain transcription factor (TEAD1). The YAP/TEAD1 complex binds to DNA element and regulates the expression of genes involved in cell growth. However, constitutive knockout of TEAD1 leads to early embryonic lethality in mice. Thus, generation of a floxed TEAD1 mouse becomes crucial for further understanding mid- to late-gestation and post-natal role of TEAD1. Herein, we created and characterized a mouse model that allows for conditional disruption of TEAD1. Embryonic fibroblasts derived from the floxed TEAD1 mice enabled the Cre-mediated deletion of TEAD1 in vitro using virally delivered Cre recombinase. Furthermore, crossing the floxed TEAD1 mouse with a ubiquitously expressing Cre mouse resulted in efficient ablation of the floxed allele in vivo, and the animals recapitulated early embryonic lethality defects. In conclusion, our data demonstrate an important role of TEAD1 in early development in mice, and the floxed TEAD1 mouse model will be a valuable genetic tool to determine the temporal and tissue-specific functions of TEAD1. PMID- 29193601 TI - A Hierarchical MFI Zeolite with a Two-Dimensional Square Mesostructure. AB - A conceptual design and synthesis of ordered mesoporous zeolites is a challenging research subject in material science. Several seminal articles report that one dimensional (1D) mesostructured lamellar zeolites are possibly directed by sheet assembly of surfactants, which collapse after removal of intercalated surfactants. However, except for one example of two-dimensional (2D) hexagonal mesoporous zeolite, no other zeolites with ordered 2D or three-dimensional (3D) mesostructures have been reported. An ordered 2D mesoporous zeolite can be templated by a cylindrical assembly unit with specific interactions in the hydrophobic part. A template molecule with azobenzene in the hydrophobic tail and diquaternary ammonium in the hydrophilic head group directs hierarchical MFI zeolite with a 2D square mesostructure. The material has an elongated octahedral morphology, and quaternary, ordered, straight, square channels framed by MFI thin sheets expanded along the a-c planes and joined with 90 degrees rotations. The structural matching between the cylindrical assembly unit and zeolite framework is crucial for mesostructure construction. PMID- 29193602 TI - The role of zinc in the treatment of acne: A review of the literature. AB - Acne vulgaris is a chronic disease of the pilosebaceous units presenting as inflammatory or noninflammatory lesions in individuals of all ages. The current standard of treatment includes topical formulations in the forms of washes, gels, lotions, and creams such as antibiotics, antibacterial agents, retinoids, and comedolytics. Additionally, systemic treatments are available for more severe or resistant forms of acne. Nevertheless, these treatments have shown to induce a wide array of adverse effects, including dryness, peeling, erythema, and even fetal defects and embolic events. Zinc is a promising alternative to other acne treatments owing to its low cost, efficacy, and lack of systemic side effects. In this literature review, we evaluate the effectiveness and side-effect profiles of various formulations of zinc used to treat acne. PMID- 29193603 TI - Quality of life in adolescents with hepatitis C treated with sofosbuvir and ribavirin. AB - Chronic HCV infection has been associated with impairment of HRQL in both adults and paediatric patients. Our aim was to assess the HRQL of HCV-positive children treated with SOF + RBV. The data for this post hoc analysis were collected in a phase 2 open-label multinational study that evaluated safety and efficacy of SOF (400 mg/day) plus RBV (weight-based up to 1400 mg/day) for 12 or 24 weeks in adolescents with chronic HCV (GS-US-334-1112). Patients and their parents/guardians completed the PedsQL-4.0-SF-15 questionnaire at baseline, at the end of treatment and in post-treatment follow-up. We included 50 adolescents with HCV genotype 2 and 3 without cirrhosis (14.8 +/- 1.9 years; male: 58%; treatment-naive: 82%; vertically transmitted HCV: 70%). After treatment, 100% of patients with HCV genotype 2 and 95% with genotype 3 achieved SVR-12. During treatment with SOF + RBV, there were no significant decrements in any of patients' self-reported or parent-proxy-reported PRO scores regardless of treatment duration (all P > .05). After treatment cessation, we recorded a statistically significant improvement in patients' self-reported Social Functioning score by post-treatment week 12: on average, +4.8 points on a 0-100 scale (P = .02). By post-treatment week 24, parent-proxy-reported School Functioning score increased by, on average, +13.0 points (P = .0065). In multivariate analysis, history of abdominal pain and psychiatric disorders were predictive of impaired HRQL in adolescents with HCV (P < .05). Adolescents with HCV do not seem to experience any HRQL decrement during treatment with SOF + RBV and experience some improvement of their HRQL scores after achieving SVR. PMID- 29193604 TI - First insights into insecticidal activity against Aedes aegypti and partial biochemical characterization of a novel low molecular mass chymotrypsin-trypsin inhibitor purified from Lonchocarpus sericeus seeds. AB - BACKGROUND: Arboviroses such as dengue, Zika and chikungunya represent a serious public health issue as a consequence of the absence of approved vaccines or specific antiviral drugs against the arboviruses that cause them. One way to prevent these diseases is by combating the vector mosquito, Aedes aegypti (Diptera), which has serine proteases in the midgut. Protease inhibitors are molecules that can block enzyme activity, impairing digestion and nutrition, which can lead to death. Thus, we purified and characterized a novel chymotrypsin trypsin inhibitor (LsCTI) from Lonchocarpus sericeus seeds and investigated its effect upon Ae. aegypti egg hatching, larval development and digestive proteases. RESULTS: LsCTI showed a single protein band in sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), and the molecular mass determined by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) was 8870.45 Da. Kinetics analyses revealed a noncompetitive type of inhibition and low inhibition constant (Ki ) for chymotrypsin (8.24 x 10-8 m). The thermal resistance was remarkable, even at 100 degrees C for 180 min. The inhibitor concentration required for 50-percent enzyme inhibition (IC50 ) of LsCTI was 4.7 x 10-7 m for Ae. aegypti midgut larval enzymes. LsCTI did not affect egg hatchability at 0.3 mg mL-1 , but caused a high larval mortality rate (77%) and delayed development (37%). CONCLUSIONS: LsCTI is a novel protease inhibitor with remarkable biochemical characteristics and is a potential tool to control Ae. aegypti development. (c) 2017 Society of Chemical Industry.

AB - The active ingredient in sunless tanning products (STPs) is a simple sugar, dihydroxyacetone (DHA). Several studies have demonstrated that DHA is absorbed within the viable layers of skin and not fully contained within the stratum corneum. Additionally, spray tanning and other aerosolized application methods have increased the risk of internal exposure through mucous membranes and inhalation. Beyond its presence in STPs, DHA also occurs as an endogenous by product of fructose metabolism, and an excess of DHA in cells can induce advanced glycation end (AGE) products and oxidative stress. Therefore, exogenous and endogenous exposures to DHA may be harmful to cells, and it has already been demonstrated that exogenous exposure to DHA is cytotoxic in immortalized keratinocytes. Still, little is known about the exogenous DHA exposure effects on other skin components. In this study, we explore the effects of exogenous DHA exposure in a human melanoma cell line, A375P. Melanoma cells were sensitive to DHA and displayed a transient burst of reactive oxygen species within an hour of exposure. Cell cycle arrest at G2/M was observed within 24 h of exposure, and apoptosis, monitored by the cleavage of PARP-1 and Caspase-3, was detected within 72 h of exposure to DHA. Together, these demonstrate that exogenous exposure to DHA has cytotoxic effects in our selected cell model and indicates the need to further investigate the exogenous exposure effects of DHA in other relevant exposure models. PMID- 29193606 TI - Real-time probe tracking using EM-optical sensor for MRI-guided cryoablation. AB - BACKGROUND: A method of real-time, accurate probe tracking at the entrance of the MRI bore is developed, which, fused with pre-procedural MR images, will enable clinicians to perform cryoablation efficiently in a large workspace with image guidance. METHODS: Electromagnetic (EM) tracking coupled with optical tracking is used to track the probe. EM tracking is achieved with an MRI-safe EM sensor working under the scanner's magnetic field to compensate the line-of-sight issue of optical tracking. Unscented Kalman filter-based probe tracking is developed to smooth the EM sensor measurements when occlusion occurs and to improve the tracking accuracy by fusing the measurements of two sensors. RESULTS: Experiments with a spine phantom show that the mean targeting errors using the EM sensor alone and using the proposed method are 2.21 mm and 1.80 mm, respectively. CONCLUSION: The proposed method achieves more accurate probe tracking than using an EM sensor alone at the MRI scanner entrance. PMID- 29193608 TI - Synthesis of Low-Dimensional Polyion Complex Nanomaterials via Polymerization Induced Electrostatic Self-Assembly. AB - Nanostructured polyion complexes (PICs) are appealing in biomaterials applications. Yet, conventional assembly suffers from the weakness in scale-up and reproducibility. Only a few low-dimensional PICs are available to date. Herein we report an efficient and scalable strategy to prepare libraries of low dimensional PICs. It involves a visible-light-mediated RAFT polymerization of ionic monomer in the presence of a polyion of the opposite charge at 5-50 % w/w total solids concentration in water at 25 degrees C, namely, polymerization induced electrostatic self-assembly (PIESA). A Vesicle, multi-compartmental vesicle, and large-area unilamellar nanofilm can be achieved in water. A long nanowire and porous nanofilm can be prepared in methanol/water. An unusual unimolecular polyion complex (uPIC)-sphere-branch/network-film transition is reported. This green chemistry offers a general platform to prepare various low dimensional PICs with high reproducibility on a commercially viable scale under eco-friendly conditions. PMID- 29193607 TI - Comparative genomics reveals that loss of lunatic fringe (LFNG) promotes melanoma metastasis. AB - Metastasis is the leading cause of death in patients with advanced melanoma, yet the somatic alterations that aid tumour cell dissemination and colonisation are poorly understood. Here, we deploy comparative genomics to identify and validate clinically relevant drivers of melanoma metastasis. To do this, we identified a set of 976 genes whose expression level was associated with a poor outcome in patients from two large melanoma cohorts. Next, we characterised the genomes and transcriptomes of mouse melanoma cell lines defined as weakly metastatic, and their highly metastatic derivatives. By comparing expression data between species, we identified lunatic fringe (LFNG), among 28 genes whose expression level is predictive of poor prognosis and whose altered expression is associated with a prometastatic phenotype in mouse melanoma cells. CRISPR/Cas9-mediated knockout of Lfng dramatically enhanced the capability of weakly metastatic melanoma cells to metastasise in vivo, a phenotype that could be rescued with the Lfng cDNA. Notably, genomic alterations disrupting LFNG are found exclusively in human metastatic melanomas sequenced as part of The Cancer Genome Atlas. Using comparative genomics, we show that LFNG expression plays a functional role in regulating melanoma metastasis. PMID- 29193609 TI - Endogenous hormone 2-methoxyestradiol suppresses venous hypertension-induced angiogenesis through up- and down-regulating p53 and id-1. AB - Brain arteriovenous malformations (AVMs) which associate with angiogenesis due to local hypertension, chronic cerebral ischaemia and tissue hypoxia usually lead to haemorrhage, however, the therapeutic medicine for the disease is still lacking. 2-methoxyestradiol (2-ME) has been shown effective in the anti-angiogenic treatment. This study was conducted to examine whether and how 2-ME could improve the vascular malformations. Intracranial venous hypertension (VH) model produced in adult male Sprague-Dawley rats and culture of human umbilical vein endothelial cells (HUVECs) at the anoxia condition were used to induce in vivo and in vitro angiogenesis, respectively. Lentiviral vectors of ID-1 and p53 genes and of their siRNA were intracranially injected into rats and transfected into HUVECs to overexpress and down-regulate these molecules. 2-ME treatment not only reduced the in vivo progression of brain tissue angiogenesis in the intracranial VH rats and the in vitro increases in microvasculature formation, cellular migration and HIF-1alpha expression induced by anoxia in HUVECs but also reversed the up regulation of ID-1 and down-regulation of p53 in both the in vivo and in vitro angiogenesis models. All of the anti-angiogenesis effects of 2-ME observed in VH rats and anoxic HUVECs were abrogated by ID-1 overexpression and p53 knockdown. Our data collectively suggest that 2-ME treatment inhibits hypoxia/anoxia-induced angiogenesis dependently on ID-1 down-regulation and p53 up-regulation, providing a potential alternative medical treatment for un-ruptured AVM patients.

We test a proposed mediating role of body concerns on breastfeeding initiation and child's age at weaning using longitudinal data for 55,522 mothers from the Norwegian Mother and Child Cohort Study (MoBa). METHODS: A linear regression-based mediation analysis with bootstrapping estimates the indirect effects of BMI on breastfeeding decisions (ever-initiation of breastfeeding, child's age at weaning, and duration of any breastfeeding beyond six months) through the variables of concern around prepregnancy weight and weight gains due to pregnancy. RESULTS: Contrary to prediction, Norwegian mothers with greater prepregnancy weight concerns had a higher likelihood of initiating breastfeeding. Concerns about weight gain during pregnancy, however, predicted earlier weaning. This relationship was the same for higher and lower BMI mothers. CONCLUSION: In this very large sample, body image affects some breastfeeding decisions. However, this effect is independent of mother's body size.

AB - Overexposure to manganese (Mn) has been known to induce alpha-synuclein (alpha Syn) oligomerization, which is degraded mainly depending on endoplasmic reticulum stress (ER stress) and autophagy pathways. However, little data reported the cross-talk between ER stress and autophagy on Mn-induced alpha-Syn oligomerization. To explore the relationship between ER stress and autophagy, we used 4-phenylbutyric acid (4-PBA, the ER stress inhibitor), rapamycin (Rap, autophagy activator) and 3-methyladenine (3-MA, autophagy inhibitor) in mice model of manganism. After 4 weeks of treatment with Mn, both ER stress and autophagy were activated. Exposed to Mn also resulted in alpha-Syn oligomerization and neuronal cell damage in the brain tissue of mice, which could be relieved by 4-PBA pretreatment. Moreover, when the ER stress was inhibited, the activation of autophagy was also inhibited. Rap pretreatment significantly activated autophagy and decreased alpha-Syn oligomers. However, 3-MA pretreatment inhibited autophagy resulting in increase of alpha-Syn oligomers, and compensatorily activated PERK signaling pathway. Our results also demonstrated that the inhibition of autophagy by 3-MA aggravated neuronal cell damage. The findings clearly demonstrated that the cross-talking between autophagy and ER stress might play an important role in the alpha-Syn oligomerization and neurotoxicity by Mn.

AB - Hepatitis B virus X protein (HBx) acts as a multifunctional protein that regulates intracellular signalling pathways during HBV infection. It has mainly been studied in terms of its interaction with cellular proteins. Here, we show that HBx induces membrane permeabilization independently of the mitochondrial permeability transition pore complex. We generated mitochondrial outer membrane mimic liposomes to observe the direct effects of HBx on membranes. We found that HBx induced membrane permeabilization, and the region comprising the transmembrane domain and the mitochondrial-targeting sequence was sufficient for this process. Membrane permeabilization was inhibited by nonselective channel blockers or by N-(n-nonyl)deoxynojirimycin (NN-DNJ), a viroporin inhibitor. Moreover, NN-DNJ inhibited HBx-induced mitochondrial depolarization in Huh-7 cells. Based on the results of this study, we can postulate that the HBx protein itself is sufficient to induce mitochondrial membrane permeabilization. Our finding provides important information for a strategy of HBx targeting during HBV treatment. PMID- 29193613 TI - Integrating Trauma-Informed Care Into Maternity Care Practice: Conceptual and Practical Issues. AB - Adverse childhood experiences have a strong negative impact on health and are a significant public health concern. Adverse childhood experiences, including various forms of child maltreatment, together with their mental health sequelae (eg, posttraumatic stress disorder, depression, dissociation) also contribute to adverse pregnancy outcomes (eg, preterm birth, low birth weight), poor postpartum mental health, and impaired or delayed bonding. Intergenerational patterns of maltreatment and mental health disorders have been reported that could be addressed in the childbearing year. Trauma-informed care is increasingly used in health care organizations and has the potential to assist in improving maternal and infant health. This article presents an overview of traumatic stress sequelae of childhood maltreatment and adversity, the impact of traumatic stress on childbearing, and technical assistance that is available from the National Center for Trauma-Informed Care (NCTIC) before articulating some steps to conceptualizing and implementing trauma-informed care into midwifery and other maternity care practices.

AB - A convergent and stereoselective total synthesis of the previously assigned structure of azaspiracid-3 has been achieved by a late-stage Nozaki-Hiyama-Kishi coupling to form the C21-C22 bond with the C20 configuration unambiguously established from l-(+)-tartaric acid. Postcoupling steps involved oxidation to an ynone, modified Stryker reduction of the alkyne, global deprotection, and oxidation of the resulting C1 primary alcohol to the carboxylic acid. The synthetic product matched naturally occurring azaspiracid-3 by mass spectrometry, but differed both chromatographically and spectroscopically. PMID- 29193616 TI - Uncatalyzed, Regioselective Oxidation of Saturated Hydrocarbons in an Ambient Corona Discharge. AB - Atmospheric pressure chemical ionization (APCI) in air or in nitrogen with just traces of oxygen is shown to yield regioselective oxidation, dehydrogenation, and fragmentation of alkanes. Ozone is produced from ambient oxygen in situ and is responsible for the observed ion chemistry, which includes partial oxidation to ketones and C-C cleavage to give aldehydes. The mechanism of oxidation is explored and relationships between ionic species produced from individual alkanes are established. Unusually, dehydrogenation occurs by water loss. Competitive incorporation into the hydrocarbon chain of nitrogen versus oxygen as a mode of ionization is also demonstrated. PMID- 29193617 TI - Clinical and molecular characterization of an emerging chromosome 22q13.31 microdeletion syndrome. AB - Microdeletion of chromosome 22q13.31 is a very rare condition. Fourteen patients have been annotated in public databases but, to date, a clinical comparison has not been done and, consequently, a specific phenotype has not been delineated yet. We describe a patient showing neurodevelopmental disorders, dysmorphic features, and multiple congenital anomalies in which SNP array analysis revealed an interstitial 3.15 Mb de novo microdeletion in the 22q13.31 region encompassing 21 RefSeq genes and seven non-coding microRNAs. To perform an accurate phenotype characterization, clinical features observed in previously reported cases of 22q13.31 microdeletions were reviewed and compared to those observed in our patient. To the best of our knowledge, this is the first time that a comparison between patients carrying overlapping 22q13.31 deletions has been done. This comparison allowed us to identify a distinct spectrum of clinical manifestations suggesting that patients with a de novo interstitial microdeletion involving 22q13.31 have an emerging syndrome characterized by developmental delay/intellectual disability, speech delay/language disorders, behavioral problems, hypotonia, urogenital, and hands/feet anomalies. The microdeletion identified in our patient is the smallest reported so far and, for this reason, useful to perform a detailed genotype-phenotype correlation. In particular, we propose the CELSR1, ATXN10, FBLN1, and UPK3A as candidate genes in the onset of the main clinical features of this contiguous gene syndrome. Thus, the patient reported here broadens our knowledge of the phenotypic consequences of 22q13.31 microdeletions facilitating genotype-phenotype correlations. Additional cases are needed to corroborate our hypothesis and confirm genotype-phenotype correlations of this emerging syndrome. PMID- 29193618 TI - Distribution of ABO/Rh blood groups and their association with hepatitis B virus infection in 3.8 million Chinese adults: A population-based cross-sectional study. AB - ABO and Rh blood groups play a vital role in blood transfusion safety and clinical practice and are thought to be linked with disease susceptibility. The results from previous studies that focused on the association between blood groups and HBV infection remain controversial. China has the world's largest burden of HBV infection. We assessed the distribution of ABO/Rh blood groups in Chinese adults and examined the association between these groups and HBV infection. We did a nationwide cross-sectional study using data from a physical check-up programme from 31 provinces examined between 2010 and 2012. ELISA was used to test for HBsAg in serologic samples. Multivariable logistic regression was used to estimate aOR of the association between ABO and Rh blood groups and HBV infection. Among 3 827 125 participants, the proportion of participants with blood group A was highest (30.54%), followed by O (30.37%), B (29.42%) and AB (9.66%). A total of 38 907 (1.02%) were Rh-D negative. The prevalence of HBsAg in blood groups O, A, B and AB were 6.34%, 5.55%, 5.18% and 5.06%, respectively. HBsAg prevalence was 5.65% in Rh-D-positive and 3.96% in Rh-D-negative participants. After controlling for other potential risk factors, multivariate models showed that participants with blood group O (adjusted OR = 1.22, 95% CI: 1.20-1.25) were at higher risk of HBV infection compared with group AB. Rh-D positive participants (adjusted OR = 1.44, 95% CI: 1.37-1.52) were at higher risk of HBV infection than Rh-D-negative participants. The associations between ABO/Rh blood groups and HBV infection were similar in subgroup analysis. The proportions of O, A, B and AB blood groups were approximately 3:3:3:1, and nearly 1 in 100 people was Rh-D negative among Chinese adults. Blood group O and Rh-D positivity were both associated with increased HBV infection. The risk of HBV infection and blood safety should be taken into consideration in clinical practice, especially when transfusing those with blood group O. Awareness and prevention of HBV infection is of particular importance for individuals with blood group O. PMID- 29193619 TI - Crystal-Field Tuning of Photoluminescence in Two-Dimensional Materials with Embedded Lanthanide Ions. AB - Lanthanide (Ln) group elements have been attracting considerable attention owing to the distinct optical properties. The crystal-field surroundings of Ln ions in the host materials can determine their energy level splitting, which is of vital importance to tailor their optical properties. 2D MoS2 single crystals were utilized as the host material to embed Eu3+ and energy-level splitting was achieved for tuning its photoluminescence (PL). The high anisotropy of the 2D host materials makes them distort the degenerate orbitals of the Ln ions more efficiently than the symmetrical bulk host materials. A significant red-shift of the PL peak for Eu3+ was observed. The strategy for tailoring the energy level splitting of Ln ions by the highly designable 2D material crystal field provides a new method to extend their optical properties. PMID- 29193620 TI - Morphometric study of adipocytes on breast cancer by means of photonic microscopy and image analysis. AB - Worldwide, breast cancer (BrCa) is currently the leading cause of deaths associated to malignant lesions in adult women. Given that some studies have mentioned that peritumoral adipocytes may contribute to breast carcinogenesis, present work sought to quantitative evaluate the morphometry of these cells in a group of adult women. Three thousand six hundred sixty four breast adipocytes, that came from biopsies of a group of adult females with different types of breast carcinomas (ductal, lobular, and mixed) and one with normal tissues, were evaluated through an image analysis (IA) process regarding six morphometric descriptors: area (A), perimeter (P), Feret diameter (FD ), aspect ratio (AR), roundness factor (RF), and fractal dimension of cellular contour (FDC ). Data showed that the adipocytes of the normal tissues group were bigger (A: 3398 +/- 2331 um2 , P: 239 +/- 83 um, and FD : 79.9 +/- 24.5 um) than those from BrCa samples (A: 2860 +/- 1933 um2 , P: 214 +/- 66 um, and FD : 73.2 +/- 22.5 um), and presented a more irregular contour (FDC of 1.370 +/- 0.037 for normal group and of 1.335 +/- 0.049 for the oncologic one). Moreover, it could be accounted that adipocytes of mixed carcinomas were largest (FD : 75.1 +/- 22.4 um) than those of lobular lesions (FD : 61.6 +/- 22.6 um), while the adipocytes of ductal carcinomas were the most oval (AR: 1.421 +/- 0.524) and roughest (FDC : 1.324 +/- 0.050) cells. IA results suggest that BrCa lesions can be categorized through a quantitative morphometric evaluation of peritumoral adipocytes. These findings could let the development of an analytical tool to help the Pathologist to enhance the accuracy of the oncologic diagnose. PMID- 29193622 TI - Erratum. PMID- 29193621 TI - Review of the association between retinal microvascular characteristics and eye disease. AB - Computerized retinal imaging technologies enable the static and dynamic measurement of a range of retinal microvascular parameters. Large population based studies have reported associations between these microvascular indices and various ophthalmic diseases including diabetes, age-related macular degeneration, retinal artery embolism, retinal vein occlusion, glaucoma and non-glaucomatous optic neuropathies. Increasingly, sophisticated imaging and analysis techniques have the potential to provide relevant clinical information regarding disease risk and progression; however, further studies are required to verify associations and strengthen the predictive power of these techniques. We summarize the current state of knowledge regarding retinal microvascular characteristics and eye disease. PMID- 29193623 TI - Cognitive and behavioral phenotype of children with pseudohypoparathyroidism type 1A. AB - Pseudohypoparathyroidism 1A (PHP1A) is a rare, genetic disorder. Most patients with PHP1A have cognitive impairment but this has not been systematically studied. We hypothesized that children with PHP1A would have lower intelligent quotient (IQ) scores than controls. To evaluate cognition and behavior, we prospectively enrolled children with PHP1A, one unaffected sibling (when available) and controls matched on BMI/age/gender/race. Evaluations included cognitive and executive function testing. Parents completed questionnaires on behavior and executive function. We enrolled 16 patients with PHP1A, 8 unaffected siblings, and 15 controls. Results are presented as mean (SD). The PHP1A group had a composite IQ of 85.9 (17.2); 25% had a composite IQ < -2 SD. The PHP1A group had significantly lower IQs than matched controls (composite IQ -17.3, 95%CI -28.1 to -6.5, p < 0.01) and unaffected siblings (composite IQ -21.5, 95%CI -33.9 to -9.1, p < 0.01). Special education services were utilized for 93% of the patients with PHP1A. Deficits were observed in executive function and parents reported delayed adaptive behavior skills and increased rates of attention deficit hyperactivity disorder. In conclusion, children with PHP1A have lower intelligence quotient scores, poorer executive function, delayed adaptive behavior skills, and increased behavior problems. PMID- 29193624 TI - Management of childhood psoriasis in France. A national survey among general practitioners, pediatricians, and dermatologists. AB - Psoriasis affects 0.5-2% of children. Severe forms required use of systemic treatments. Few studies are published on efficiency and tolerance of systemic treatments in children. We conducted a survey in France to better understand management of children with psoriasis. A survey on childhood psoriasis management was sent by e-mail to GPs, pediatricians, and dermatologists. The survey included 384 physicians. Respectively 53.1%, 49.8%, and 83.3% of GPs, pediatricians, and dermatologists declare to have seen at least one child with psoriasis during the 3 previous months. Less than 5% of GPs and pediatricians used severity score versus 23.7% of dermatologists. If most of physicians declare to use local treatments, less than 5% of GPs and pediatricians used systemic treatments. 32.4% of dermatologists declared to use at least one systemic treatment, but only 2.9% to use the 4 systemic treatments available in France. This survey shows that only half of GPs and pediatricians see children with psoriasis, but most of dermatologists. However, the management of severe forms seems limited by the underuse of severity scores and systemic treatments. These results should stimulate dermatology societies to promote prospective studies and guidelines in young populations with psoriasis. PMID- 29193625 TI - Agreement Between Actigraphy and Diary-Recorded Measures of Sleep in Children With Epilepsy. AB - PURPOSE: To describe sleep patterns in young children with epilepsy and to examine levels of agreement between measurements derived from actigraphy and diary recordings. DESIGN: Cross-sectional study. METHODS: Eighty-nine toddlers and preschool-aged children with epilepsy wore an actigraph on their wrists for 7 consecutive days. Parents and caregivers maintained a concurrent sleep diary while the child was wearing the monitor. Levels of agreement between actigraphy and diary recordings were examined using the Bland and Altman method separately for all recording days, weekdays, and weekends. FINDINGS: Discrepancies between actigraphy-derived and diary-documented sleep onset, sleep offset, actual sleep at night, wake after sleep onset, and daytime sleep were +/-35, +/-15, +/-82, +/ 70, and +/-29 min, respectively. Differences between actigraphy and diary-derived sleep variables were consistently greater for weekends than for weekdays. Discrepancies between actigraphy and diary-derived actual sleep at night were significantly greater for children who slept alone than for those who co-slept with a parent. CONCLUSIONS: Our study demonstrates an acceptable agreement between actigraphy and diary recordings for sleep onset, sleep offset, and daytime sleep, but insufficient agreement for actual sleep at night and wake after sleep onset, with parents of children sleeping alone more likely to misestimate child sleep behaviors. Deviation of weekend sleep from weekdays further decreased the accuracy of parental sleep estimates and increased the discrepancies between actigraphy and diary. CLINICAL RELEVANCE: Sleep in children with epilepsy assessed using diary recordings alone could be misleading, and actigraphy should be preferred over diaries when resources are available.

PMID- 29193627 TI - A Vinyl Sulfone-Based Fluorogenic Probe Capable of Selective Labeling of PHGDH in Live Mammalian Cells. AB - Chemical probes are powerful tools for interrogating small molecule-target interactions. With additional fluorescence Turn-ON functionality, such probes might enable direct measurements of target engagement in live mammalian cells. DNS-pE (and its terminal alkyne-containing version DNS-pE2) is the first small molecule that can selectively label endogenous 3-phosphoglycerate dehydrogenase (PHGDH) from various mammalian cells. Endowed with an electrophilic vinyl sulfone moiety that possesses fluorescence-quenching properties, DNS-pE/DNS-pE2 became highly fluorescent only upon irreversible covalent modification of PHGDH. With an inhibitory property (in vitro Ki =7.4 MUm) comparable to that of known PHGDH inhibitors, our probes thus offer a promising approach to simultaneously image endogenous PHGDH activities and study its target engagement in live-cell settings. PMID- 29193628 TI - Integration of a faculty's ongoing research into an undergraduate laboratory teaching class in developmental biology. AB - Traditional developmental biology laboratory classes have utilized a number of different model organisms to allow students to be exposed to diverse biological phenomena in developing organisms. This traditional approach has mainly focused on the diverse morphological and anatomical descriptions of the developing organisms. However, modern developmental biology is focusing more on conserved genetic networks which are responsible for generating conserved body patterns in developing organisms. Therefore, it is necessary to develop a new pedagogical tool to educate undergraduate biology students in the laboratory class of developmental biology with the genetic principles which are responsible for generating and controlling the developing body patterns. A new undergraduate laboratory class for developmental biology was developed in order to offer students the opportunity to explore a wide range of experimental procedures, also incorporating the instructor's on-going research. Thereby the course can serve as a bridge between research and education by combining both into a single theme. The course design involves a sequence of exercises which can be easily adapted to the faculty's ongoing research. This style of laboratory coursework could be a transitional form between a regular laboratory course and a discovery-based laboratory course.

PMID- 29193629 TI - Relationship between the severity of cerebral white matter hyperintensities and sympathetic nervous activity in older adults. AB - AIM: White matter hyperintensities (WMH), visualized on brain magnetic resonance imaging, represent an abnormality related to the development of geriatric syndromes. Recently, it has been found that low sympathetic nervous activity might be associated with physical and cognitive dysfunction in older adults. Therefore, we investigated the relationship between the severity of cerebral WMH and sympathetic nervous activity, measured by the heart rate variability. METHODS: We carried out a cross-sectional study of 39 older patients. Holter recording was carried out for 30 min. From the RR intervals on the electrocardiogram, the standard deviation of the normal-to-normal intervals, the standard deviation of all normal-to-normal intervals in all the five segments of the entire recording, low frequency (LF), high frequency (HF) and LF/HF were calculated. In regard to the WMH, periventricular hyperintensities and deep white matter hyperintensities (DWMH) were rated according to the Fazekas classification. The WMH were also rated semiquantitatively according to the methods developed by Junque (periventricular hyperintensities) and de Groot (DWMH). RESULTS: The LF/HF showed significant negative correlations with the total and regional periventricular hyperintensities, as well as DWMH. Multiple regression analysis showed that the negative associations remained significant between the LF/HF and DWMH (total, temporal, occipital). Furthermore, fall risk index significantly correlated with the LF/HF, total and the occipital DWMH. CONCLUSIONS: The severity of the DWMH was associated with the LF/HF and the fall risk, one of the important geriatric syndromes, suggesting that WMH, sympathetic nervous dysfunction and geriatric syndrome are interrelated to each other.

PMID- 29193631 TI - An audit of change in clinical practice: from oxygen-driven to air-driven nebulisers for prehospital patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). AB - BACKGROUND: In developed countries, ambulances normally carry oxygen cylinders, but not compressed air. Treatment of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) with oxygen-driven nebulisers can result in hypercapnia and acidosis. Attempts to avoid this have involved interrupted administration of oxygen. However, small battery-powered air nebulisers are now available. This study aims to compare the prehospital oxygen saturations and treatment of patients suffering from AECOPD before and after the introduction of air nebulisers. METHODS: The oxygen saturations and treatment of 200 AECOPD patients before and 200 AECOPD patients after the introduction of air nebulisers were compared. Compliance with a target saturation of 88-92% was calculated. RESULTS: The median final oxygen saturation was lower for the post-intervention category (94%) than the pre-intervention category (96%). There was an increase in air nebuliser use from 0 to 56% (P < 0.001) and a decrease in oxygen use from 100 to 71.5% (P < 0.001). There was a numerical increase in the proportion of patients arriving at hospital with oxygen saturations of 88-92% following introduction of the air nebulisers (24 vs 16.5%) and a decrease in patients arriving with high saturations (67.5 vs 76.5%). The likelihood of achieving the target oxygen saturations following introduction of air nebulisers increased (odds ratio 1.598; 95% confidence interval 0.974, 2.621). CONCLUSION: The introduction of prehospital air nebulisers resulted in a reduction in oxygen therapy in patients with AECOPD and a lower median prehospital oxygen saturation. This study supports the use of air nebulisers in the prehospital setting. PMID- 29193632 TI - Lip repositioning for the treatment of excess gingival display: A systematic review. AB - BACKGROUND: Lip repositioning is a conservative surgical technique used to treat excess gingival display. An array of modifications has been introduced to the technique over time and as studies show the technique and its modifications to be successful, there is little standardized information for clinicians to make informed decisions when choosing this technique for the treatment of patients with excessive gingival display (EGD). OBJECTIVES: To review the current literature on the topic of lip repositioning for the treatment of excessive EGD, exploring outcome, and result longevity. METHODS: A structured systematic search was carried out using the Ovid database and Web of Science to identify published studies on lip repositioning technique. Search was restricted to studies in the English language, describing a surgical intervention. Case reports were included as the number of published studies was limited. RESULTS: The electronic search identified 93 articles, hand search identified 1 article, and reference search identified 1 article. After excluding duplicates and screening articles, a total of 22 articles met the inclusion criteria. An estimated mean improvement of 3.4 mm (95% confidence interval, 3.0-3.8 mm) was found possible with lip repositioning. Data analysis was performed using only 4 studies, amounting to a total of 33 patients. Potential risk of bias was identified in some of the studies included. CONCLUSIONS: Despite the limited available studies on lip repositioning, an estimated mean improvement of 3.4 mm was found to be possible with surgical lip repositioning, suggesting that the technique could be used successfully to treat EGD. However, more studies are necessary to properly evaluate the treatment approach and stability of the technique. CLINICAL SIGNIFICANCE: Recently, the demand for esthetics has significantly increased, driven by increased patient awareness and the search for an ideal smile. Creating the perfect smile is an intricate process that requires a multidisciplinary approach, with careful consideration of the lips and the gingival outline. Excess gingival display results in an unaesthetic smile, lip repositioning offers a comparatively simple solution for this problem. While the quality literature on this topic is limited statistical analysis of collected studies show that an estimated mean improvement of 3.4 mm can be achieved with surgical lip repositioning. PMID- 29193633 TI - Evidence-based dentistry can effectively be taught to dental care professional students - A mixed methods study. AB - BACKGROUND: Little research exists in the teaching of evidence-based dentistry (EBD) to students in the fields of dental hygiene, dental nursing and orthodontic therapy. This study aims to analyse the effect of a 1-day EBD programme on knowledge and confidence whilst also gaining insight into students' experience of the intervention. METHOD: A mixed methods study was utilised with explanatory sequential design. The population consisted of dental hygiene (DH), dental nursing (DN) and orthodontic therapy (OT) students (N = 44). The intervention consisted of a 1-day active learning EBD programme, delivered via group projects and lectures. In the initial quantitative phase, a standardised questionnaire pre and post -intervention measured changes in confidence for all participants, whilst change in knowledge was measured for DH and OT students only. Following this, focus groups were scheduled for all members of each discipline 3 months post-intervention for DN and 2 months post-intervention for DH and OT students. Semi-structured focus group schedules were drawn up, and groups organised according to the outcomes of quantitative data analysis. Qualitative results were analysed using a deductive adaptation of Burnard's thematic content analysis. RESULTS: Forty-two students took part (94.45%) in this study. Median knowledge scores increased from zero to two of five (P < .001), whilst median confidence score doubled from four to eight of eight (P < .001). Results of thematic content analysis were coincident with quantitative results; however, it also provided constructive feedback regarding design and content of the course. CONCLUSIONS: A 1-day bespoke programme in EBD increased students' confidence and knowledge in EBD skills. However, the findings further suggest that two successive half-day training sessions instead of one full-day training, tied in with coursework that requires the application of the acquired skills, may increase the learning experience further. PMID- 29193634 TI - Comparative study on the liquid chromatographic enantioseparation of cyclic beta amino acids and the related cyclic beta-aminohydroxamic acids on Cinchona alkaloid-based zwitterionic chiral stationary phases. AB - The enantiomeric pairs of cis and trans stereoisomers of cyclic beta aminohydroxamic acids and their related cis and trans cyclic beta-amino acids containing two chiral centers were directly separated on four structurally related chiral stationary phases derived from quinine and quinidine modified with (R,R)- and (S,S)-aminocyclohexanesulfonic acids. Applying these zwitterionic ion exchangers as chiral selectors, the effects of the composition of the bulk solvent, the acid and base additives, the structures of the analytes, and temperature on the enantioresolution were investigated. To study the effects of temperature and obtain thermodynamic parameters, experiments were carried out at constant mobile phase compositions in the temperature range 5-50 degrees C. The differences in the changes in standard enthalpy Delta(DeltaH degrees ), entropy Delta(DeltaS degrees ), and free energy Delta(DeltaG degrees ) were calculated from the linear van't Hoff plots derived from the ln alpha versus 1/T curves in the studied temperature range. Results thus obtained indicated enthalpy-driven separations in all cases. The sequence of elution of the enantiomers was determined and found to be reversed when ZWIX(-)TM was changed to ZWIX(+)TM or ZWIX(-A) to ZWIX(+A). PMID- 29193636 TI - Depression, Perceived Health, and Right-of-Return Hopefulness of Palestinian Refugees. AB - PURPOSE: Displacement is traumatic and often an unwanted social change that can lead to a loss of identity and socioeconomic, physical, and psychological livelihood. The purpose of the study was to describe the association of perceived health and right-of-return hopefulness to depressive symptom severity in Palestinian refugees, taking into consideration gender and poverty. DESIGN: The descriptive, correlational study was framed within a socioecological lens. Data collection occurred between October 2015 and November 2015 in Amman, Jordan, which hosts the most Palestinian refugees in the world. The participants in the sample (N = 177) had a mean age of 36.9 years. METHODS: Participants responded to the Patient Health Questionnaire for depressive symptom severity, the RAND-36 perceived health item, and a statement about hopefulness to return to Palestine. Descriptive, correlation, and logistic and linear regression analyses were computed. FINDINGS: Results showed that 43% of participants had moderate to severe depressive symptoms, 42% lived in poverty, and 20% had fair or poor health; yet, 60% were hopeful about returning to Palestine. Participants who had better perceived health and right-of-return hopefulness were less likely to have symptoms of major depression. Perceived health was the only factor-not gender, poverty, or right-of-return hopefulness-that explained the variance in depressive symptoms. CONCLUSIONS: Palestinian adult refugees in Jordan exhibited symptoms of major depression that were associated with poorer perceived health and less hopefulness about repatriation to Palestine. CLINICAL RELEVANCE: Nurses with community or mental health specialization can play a major role by systematically screening refugees for depression using worldwide, evidence-based tools and by advocating for policies that can improve the health and living conditions of refugees. PMID- 29193635 TI - Inactivation of AMMECR1 is associated with growth, bone, and heart alterations. AB - We report five individuals with loss-of-function of the X-linked AMMECR1: a girl with a balanced X-autosome translocation and inactivation of the normal X chromosome; two boys with maternally inherited and de novo nonsense variants; and two half-brothers with maternally inherited microdeletion variants. They present with short stature, cardiac and skeletal abnormalities, and hearing loss. Variants of unknown significance in AMMECR1 in four male patients from two families with partially overlapping phenotypes were previously reported. AMMECR1 is coexpressed with genes implicated in cell cycle regulation, five of which were previously associated with growth and bone alterations. Our knockdown of the zebrafish orthologous gene resulted in phenotypes reminiscent of patients' features. The increased transcript and encoded protein levels of AMMECR1L, an AMMECR1 paralog, in the t(X;9) patient's cells indicate a possible partial compensatory mechanism. AMMECR1 and AMMECR1L proteins dimerize and localize to the nucleus as suggested by their nucleic acid-binding RAGNYA folds. Our results suggest that AMMECR1 is potentially involved in cell cycle control and linked to a new syndrome with growth, bone, heart, and kidney alterations with or without elliptocytosis.

AB - Alopecia areata (AA) is an autoimmune disease characterized by non-cicatricial hair loss. No definitive therapy currently exists for AA. To compared the efficacy and safety of the mometasone furoate 0.1% cream alone with the mometasone furoate 0.1% cream plus adapalene 0.1% gel in treatment of AA. Twenty patients with AA and with mean age of 27.4 +/- 9.2 years were enrolled. Patches with a diameter of < 5 cm were treated with mometasone furate 0.1% cream (M), and patches with a diameter of >=5 cm were treated with mometasone furate 0.1% cream plus adapalene 0.1% gel (M + D) for a period of 12 weeks. Hair regrowth was evaluated using a Re-growth score (RGS). Mean RGSs of M + D group were higher than M group for 4th week (2.60 vs. 1.45); 8th week (3.85 vs. 2.40) and 12th week (4.40 vs. 3.30). Mean percentages of hair re-growth in M + D group were statistically higher than M group for 4th (50.2% vs. 23.5%), 8th (78.5% vs. 50.7%), and 12th week (90.5% vs. 71%). Study revealed the efficacy and safety of adapalene and mometasone furoate combination in AA. Adapalene can be used as a new therapeutic modality in AA. PMID- 29193638 TI - Delayed diagnosis of atrial fibrillation after first-ever stroke increases recurrent stroke risk: a 5-year nationwide follow-up study. AB - BACKGROUND: Delayed detection of atrial fibrillation (AF) is common in patients with stroke. However, it is not well known whether delayed identification of AF in patients with stroke affects the prognosis of patients. AIMS: To evaluate the association between the timing of AF diagnosis after stroke and clinical outcomes. METHODS: We identified a cohort of all patients admitted with a primary diagnosis of first-ever ischaemic stroke, which was categorised into three groups, namely, non-AF, AF presenting with stroke and delayed AF diagnosis groups. The study patients were individually followed for 5 years to evaluate the occurrence of recurrent stroke and death. RESULTS: In total, 17 399 patients were hospitalised with first-ever ischemic stroke, of whom 16 261 constituted the non AF group, 907 the AF presenting with stroke group and 231 the delayed AF diagnosis group. During the 5-year follow up, 2773 (17.1%), 175 (19.3%) and 68 (29.4%) patients in the non-AF, AF presenting with stroke and delayed AF diagnosis groups, respectively, were hospitalised for recurrent stroke. The delayed AF diagnosis group exhibited a 1.57-times higher risk of recurrent stroke than the AF presenting with stroke group, after adjustment for the CHA2DS2-VASc scores (adjusted hazard ratio (HR): 1.57; 95% confidence interval (CI) = 1.19 2.08; P = 0.002). In addition, delayed diagnosis of AF significantly increased the risk of recurrent stroke in men, but not in women, after adjustment for the CHA2DS2-VASc scores. CONCLUSION: Delayed diagnosis of AF after stroke increased the risk of recurrent stroke, particularly in men. PMID- 29193639 TI - Oligonephronia and Wolf-Hirschhorn syndrome: A further observation. AB - Wolf-Hirschhorn syndrome (WHS) is a rare chromosomal disorder caused by a partial deletion of chromosome 4 (4p16.3p16.2). We describe a case of a male 9 years old children with WHS proteinuria and hypertension. Laboratory data showed creatinine 1.05 mg/dl, GFR 65.9 ml/min/1.73 m2 , cholesterol 280 mg/dl, triglyceride 125 mg/dl with electrolytes in the normal range. Urine collection showed protein 2.72 g/L with a urine protein/creatinine ratio (UP /UCr ratio) of 4.2 and diuresis of 1,100 ml. Renal ultrasound showed reduced kidney dimensions with diffusely hyperechogenic cortex and poorly visualized pyramids. Renal biopsy showed oligonephronia with focal segmental glomerulosclerosis associated with initial tubulointerstitial sclerotic atrophy. The child began therapy with Angiotensin converting enzyme inhibitors (ACE-inhibitors) to reduce proteinuria and progression of chronic kidney disease. In the literature the anomalies of number of glomeruli oligonephronia and oligomeganephronia (OMN) are described in two forms, one without any associated anomalies, sporadic, and solitary and the other with one or more anomalies. Our review of the literature shows that the pathogenesis of this anomaly is unknown but the role of chromosome 4 is very relevant. Many cases of OMN are associated with anomalies on this chromosome, in the literature cases series we observed this association in 14/48 cases (29.2%) and in 7 of these 14 cases with WHS. Our case and the review of literature demonstrate how periodic urinalysis and renal ultrasound monitoring is recommended in patients affected by WHS and the renal biopsy must be performed when there is the onset of proteinuria. PMID- 29193640 TI - Rise of the zombie institution, the failure of mental health nursing leadership, and mental health nursing as a zombie category. AB - In this paper, we propose that mental health nursing has become a zombie category, at least in the Australian context. Mental health nursing is a concept that has lost any real explanatory or conceptual power, yet nevertheless persists in public discourse and the collective imagination. In recent decades, powerful forces have contributed to the zombification of the mental health nursing workforce and the academy. An increase in medical hegemony, the ascendancy of allied health in mental health service provision, the need for uncritical and servile workers, protocol-driven work practices, and a failure of leadership to mobilize any substantial resistance to these trends have enabled the infection to spread. The recognition of zombification, active resistance against the forces that conspire to cause it, and the cultivation of genuine conscientious critical thought and debate offer the only hope of survival of mental health nursing as a thriving specialty. PMID- 29193641 TI - Comparison of passive and active leisure activities and life satisfaction with aging. AB - AIM: Many older adults face limitations to participating in active leisure activities as a result of their physical constraints from aging. Passive leisure activities become alternative leisure activities for older adults as a result of limited physical capacity. The present study sought to determine whether there exists a difference in the frequency of participation in passive and active leisure activities, and the effect of participation in passive and active leisure activities on the life satisfaction level of old adults. METHODS: A total of 460 participants aged 60-95 years were randomly selected from 21 sites in the USA. The Life Satisfaction Index - Z and the Meaningful Activity Participation Assessment were analyzed to examine older adults' life satisfaction and frequency of active or passive activities. RESULTS: The results showed that participation in passive leisure activities, such reading, talking on the telephone and watching TV/listening to the radio, is more frequent among older adults (P = 0.000). The regression coefficient found that club/organization or volunteering (P = 0.008), homemaking/maintenance (P = 0.017) and traveling (P = 0.017) for active leisure activities were statistically significant predictors of Life Satisfaction Index - Z for older adults. CONCLUSIONS: The current study shows that older adults spent much more times participating in passive leisure activities, such as radio/watching TV, talking on the phone and reading. The result also showed that active leisure activities, such as club/organization or volunteering, home making/maintenance and traveling, were significant predictors of life satisfaction for older adults controlling for covariates. The current study suggests marketing and programming plans to overcome the constraints that influence older adults' life satisfaction. Geriatr Gerontol Int 2018; 18: 380 386.

AB - Active constraint (AC)/virtual fixture (VF) is among the most popular approaches towards the shared execution of subtasks by the surgeon and robotic systems. As more possibilities appear for the implementation of ACs in surgical scenarios, the need to introduce methods that guarantee a safe and intuitive user interaction increases. The presence of the human in the loop adds a layer of interactivity and adaptability that renders the assessment of such methods non trivial. In most works, guidance ACs have been evaluated mainly in terms of enhancement of accuracy and completion time with little regard for other aspects such as human factors, even though the continuous engagement of these methods can considerably degrade the user experience. This paper proposes a set of performance metrics and considerations that can help evaluate guidance ACs with reference to accuracy enhancement, force characteristics and subjective aspects. The use of these metrics is demonstrated through two sets of experiments on 12 surgeons and 6 inexperienced users. PMID- 29193644 TI - The use of needle holders in CTF guided biopsies as a dose reduction tool. AB - PURPOSE: The purpose of this study was to evaluate the efficacy of needle holders in reducing staff hand exposure during biopsies guided by computed tomography fluoroscopy (CTF), through the analysis of data acquired during a detailed monitoring study, undertaken in parallel with an ongoing optimization process to reduce hand irradiation. METHODS: Hand monitoring was performed with 11 extremity detectors, two per finger (base and tip) and one on the back of the wrist, for the left (dominant) hand, during two series of biopsies with comparable characteristics. The first series (47 biopsies) were performed with only quick check method (QC) and occasional side-handle (SH) manipulation of the needle. The second series (63 biopsies) were performed after introducing needle holders (NH) in the course of an optimization process. RESULTS: Choice of technique (QC, QC + NH, QC + SH) by the interventional radiologist (IR) was related to biopsy difficulty. Measured hand exposure was low (< 1 mSv) for all QC-only procedures, and for most of the QC + NH procedures. Occasional side-handle manipulation still occurred during challenging biopsies, so that 8% of biopsies in the second series accounted for ~70% of total fingertip dose (~90 mSv). The methodology used allowed a detailed insight into the dose reduction achievable with needle holders during real procedures, without the limitations of phantom measurements. CONCLUSIONS: Needle holders proved effective in reducing mean hand exposure during clinical procedures where real-time manipulation was necessary. Occasional side-handle manipulation was found to contribute disproportionately to hand exposure. This highlights the importance of individual hand monitoring during CTF guided procedures. PMID- 29193645 TI - MAPK inhibitors induce serine peptidase inhibitor Kazal type 1 (SPINK1) secretion in BRAF V600E-mutant colorectal adenocarcinoma. AB - The mitogen-activated protein kinase (MAPK) pathway plays a central role in colorectal cancers (CRC). In particular, BRAF V600E-mutant tumors, which represent around 10% of CRCs, are refractory to current therapies. Overexpression and secretion of serine peptidase inhibitor Kazal type 1 (SPINK1) are observed in around 50% of CRCs, and its serum level can be used as a biomarker for poor prognosis. Utilizing a recently developed extendable blocking probe assay, we analyzed the BRAF mutation status in a CRC patient cohort (N = 571) using tissue derived RNA as the starting material. From the same RNA samples, we measured the relative SPINK1 expression levels using a quantitative real-time PCR method. Expression of mutant BRAF V600E correlated with poor prognosis, as did low expression of SPINK1 mRNA. Further, BRAF V600E correlated negatively with SPINK1 levels. In order to investigate the effect of MAPK pathway-targeted therapies on SPINK1 secretion, we conducted in vitro studies using both wild-type and V600E CRC cell lines. BRAF inhibitor vemurafenib, and subsequent MAPK pathway inhibitors trametinib and SCH772984, significantly increased SPINK1 secretion in V600E CRC cell lines Colo205 and HT-29 with a concomitant decrease in trypsin-1 and -2 secretion. Notably, no SPINK1 increase or trypsin-1 decrease was observed in BRAF wild-type CRC cell line Caco-2 in response to MAPK pathway inhibitors. In further mechanistic studies, we observed that only trametinib was able to diminish completely both MEK and ERK phosphorylation in the V600E CRC cells. Furthermore, the key regulator of integrated stress response, activating transcription factor 4 (ATF-4), was downregulated both at mRNA and at protein level in response to trametinib treatment. In conclusion, these data suggest that sustained inhibition of not only MAPK pathway activation, but also ATF-4 and trypsin, might be beneficial in the therapy of BRAF V600E-mutant CRC and that SPINK1 levels may serve as an indicator of therapy response. PMID- 29193646 TI - Quantifying the hidden healthcare cost of diabetes mellitus in Australian hospital patients. AB - BACKGROUND: Diabetes mellitus in hospital inpatients is most commonly present as a comorbidity rather than as the primary diagnosis. In some hospitals, the prevalence of comorbid diabetes mellitus across all inpatients exceeds 30%, which could add to complexity of care and resource utilisation. However, whether and to what extent comorbid diabetes mellitus contributes indirectly to greater hospitalisation costs is ill-defined. AIM: To determine the attributable effect of comorbid diabetes mellitus on hospital resource utilisation in a General Internal Medical service in Melbourne, Australia. METHODS: We extracted data from a database of all General Internal Medical discharge episodes from July 2012 to June 2013. We fitted multivariable regression models to compare patients with diabetes mellitus to those without diabetes mellitus with respect to hospitalisation cost, length of stay, admissions per year and inpatient mortality. RESULTS: Of 4657 patients 1519 (33%) had diabetes mellitus, for whom average hospitalisation cost (AUD9910) was higher than those without diabetes mellitus (AUD7805). In multivariable analysis, this corresponded to a 1.22-fold (95% confidence interval (CI) 1.12-1.33, P < 0.001) higher cost. Mean length of stay for those with diabetes was 8.2 days versus 6.8 days for those without diabetes, with an adjusted 1.19-fold greater odds (95% CI 1.06-1.33, P = 0.001) of staying an additional day. Number of admissions and mortality were similar. CONCLUSION: Comorbid diabetes mellitus adds significantly to hospitalisation duration and costs in medical inpatients. Moreover, diabetes mellitus patients with chronic complications had a greater-still cost and hospitalisation duration compared to those without diabetes mellitus. PMID- 29193647 TI - The incidence, characteristics, management and outcomes of anaphylaxis in pregnancy: a population-based descriptive study. AB - OBJECTIVE: The aim of this study was to estimate the incidence of anaphylaxis in pregnancy and describe the management and outcomes in the UK. DESIGN: A population-based descriptive study using the UK Obstetric Surveillance System (UKOSS). SETTING: All consultant-led maternity units in the UK. POPULATION: All pregnant women who had anaphylaxis between 1 October 2012 and 30 September 2015. Anaphylaxis was defined as a severe, life-threatening generalised or systemic hypersensitivity reaction. METHODS: Prospective case notification using UKOSS. MAIN OUTCOME MEASURES: Maternal mortality, severe maternal morbidity, neonatal mortality and severe neonatal morbidity. RESULTS: There were 37 confirmed cases of anaphylaxis in pregnancy, giving an estimated incidence of 1.6 (95% CI: 1.1 2.2) per 100 000 maternities. Four cases of anaphylaxis were in women with known penicillin allergies: two received co-amoxiclav and two cephalosporins. Twelve women had anaphylaxis following prophylactic use of antibiotics at the time of a caesarean delivery. Prophylactic use of antibiotics for Group B streptococcal infection accounted for anaphylaxis in one woman. Two women died (5%), 14 (38%) women were admitted to intensive care and seven women (19%) had one or more additional severe maternal morbidities, which included three haemorrhagic events, two cardiac arrests, one thrombotic event and one pneumonia. No infants died; however, in those infants whose mother had anaphylaxis before delivery (n = 18) there were seven (41%) neonatal intensive care unit admissions, three preterm births and one baby was cooled for neonatal encephalopathy. CONCLUSIONS: Anaphylaxis is a rare severe complication of pregnancy and frequently the result of a reaction to antibiotic administration. This study highlights the seriousness of the outcomes of this condition for the mother. The low incidence is reassuring given the large proportion of the pregnant population that receive prophylactic antibiotics during delivery. TWEETABLE ABSTRACT: Anaphylaxis is a rare severe complication of pregnancy and frequently the result of a reaction to antibiotic administration. PMID- 29193648 TI - The importance of trifluoromethyl pyridines in crop protection. AB - The pyridine ring, substituted by a trifluoromethyl substituent has been successfully incorporated into molecules with useful biological properties. During the period 1990 to September 2017, 14 crop protection products bearing a trifluoromethyl pyridine have been commercialized or proposed for an ISO common name, covering fungicides, herbicides, insecticides and nematicides. Chemical processes have been developed to provide trifluoromethyl pyridine intermediates, from non-fluorinated pyridine starting materials, at scale and with affordable costs of goods. These attractive starting materials were readily adopted by research chemists, and elaborated through simple chemical modifications into new active ingredients. In a second approach, substituted trifluoromethyl pyridine rings have been constructed from acyclic, trifluoromethyl starting materials, which again has served to identify new active ingredients. Molecular matched pair analysis reveals subtle, yet important differences in physicochemical and agronomic properties of trifluoromethyl pyridines compared with the phenyl analogues. This review focuses on the past 27 years, seeking to identify reasons behind the success of such research programmes, and inspire the search for new crop protection chemicals containing the trifluoromethyl pyridine ring.

AB - Infantile hemangioma (IH) is the most common benign tumor of childhood, with a prevalence of 4 % to 10 %. It is characterized by a proliferative rapid growth phase, which starts after a few weeks of life, followed by a slow regression phase. In IH cases that are potentially disfiguring or life-threatening (10 % to 15 % of all cases), systemic therapy should be promptly initiated. Data source The present study reviews published scientific articles available in reliable electronic databases. Selected were all studies that evaluated the pathogenesis of IH and the mechanisms of action of propranolol. Conclusions The pathogenesis of IH has not been fully elucidated. Studies show that, in the proliferative phase of IH, there is an imbalance of angiogenic factors and an increase in the levels of vascular endothelial growth factor and matrix metalloproteinases 2 and 9. In the regression phase, the levels of these factors decrease, whereas those of antiangiogenic factors, including tissue inhibitors of matrix metalloproteinases, increase. Since 2008, propranolol has become the drug of choice in the treatment of IH, targeting vascular tone, angiogenesis, and apoptosis. Current insights into the pathogenesis of IH allow for the development of new therapeutic strategies. PMID- 29193650 TI - Effect of characteristics of pharmacotherapy on non-adherence in chronic cardiovascular disease: A systematic review and meta-analysis of observational studies. AB - INTRODUCTION: Cardiovascular medications are effective in prevention of cardiovascular diseases (CVD); however, medication non-adherence contributes to morbidity and mortality. OBJECTIVE: This systematic review and meta-analysis aims to summarise the evidence regarding the relationship between characteristics of drug therapy (pharmacotherapy) and medication non-adherence in the CVD population. METHODS: Systematic searches in PubMed, LILACS, Academic Search and CINAHL databases for observational studies that enrolled adults with CVD were performed, from January 1960 to December 2015. The meta-analysis tested the association between characteristics of pharmacotherapy and self-reported medication non-adherence outcome, using a random effects model. To investigate heterogeneity, we performed subgroup analysis and sensitivity analysis. RESULTS: Twenty-four cross-sectional studies and 7 cohort studies were included in this review. Based on 31 studies including 27 441 participants, we performed meta analyses for all the characteristics of drug therapy that at least 2 studies evaluated, with a total of fourteen meta-analyses. The pooled results showed that studies which evaluate whether participants have insurance or another program that assists with medication costs, but not full coverage (OR = 0.63; 95% CI: 0.53-0.74; P < .001; I2 = 0%, P = .938), and a dosing frequency of twice or more daily (OR = 1.38; 95% CI: 1.13-1.69; P < .001) were associated with non adherence. CONCLUSIONS AND RELEVANCE: The results of this review suggest that access to insurance or another program that assists with medication costs was a protection factor for non-adherence. On the other hand, a high frequency of dosing was a risk factor for non-adherence. Therefore, these characteristics of pharmacotherapy must be considered to improve medication adherence among CVD patients. PMID- 29193651 TI - Platelet-Facilitated Photothermal Therapy of Head and Neck Squamous Cell Carcinoma. AB - Here, we present a platelet-facilitated photothermal tumor therapy (PLT-PTT) strategy, in which PLTs act as carriers for targeted delivery of photothermal agents to tumor tissues and enhance the PTT effect. Gold nanorods (AuNRs) were first loaded into PLTs by electroporation and the resulting AuNR-loaded PLTs (PLT AuNRs) inherited long blood circulation and cancer targeting characteristics from PLTs and good photothermal property from AuNRs. Using a gene-knockout mouse model, we demonstrate that the administration of PLT-AuNRs and localizing laser irradiation could effectively inhibit the growth of head and neck squamous cell carcinoma (HNSCC). In addition, we found that the PTT treatment augmented PLT AuNRs targeting to the tumor sites and in turn, improved the PTT effects in a feedback manner, demonstrating the unique self-reinforcing characteristic of PLT PTT in cancer therapy.

AB - This study aimed to investigate the incidence and risk factors of deep surgical site infection (DSSI) during hospitalisation after closed tibial plateau fractures treated with open reduction and internal fixation (ORIF). We performed this retrospective study at a university-affiliated hospital with an advanced trauma centre. The data of adult patients with closed tibial plateau fractures treated with ORIF from January 2012 to February 2017 were extracted from the electronic medical records. Demographics, injury-related and surgery-related variables of DSSI and non-DSSI groups were compared by univariate test. Multivariate logistic analysis models were used to investigate the independent risk factors. In total, 676 patients with complete data met the inclusion criteria and were included, and of them, 17 developed DSSI (2.51%) during hospitalisation. Approximately 60% (9/17) of DSSI was caused by Staphylococcus aureus. Compared to the non-DSSI group, DSSI patients had a significantly longer stay in hospital (25.8 vs 15.2 days). Independent risk factors of DSSI identified by multivariate analysis were higher BMI (>26.0) (OR, 1.58; 95% CI, 1.09 to 3.27; P = 0.032), prolonged surgical duration (>138 min) (OR, 4.26; 95% CI, 1.54 to 11.19; P = 0.005) and current smoking (OR, 3.42; 95% CI, 1.47 to 8.62; P = 0.01). A relatively low incidence rate of DSSI (2.51%) was found in this study, and several significant risk factors were identified. Smoking cessation programmes should be implemented immediately after hospitalisation, especially for obesity and morbid obesity patients. Detailed and comprehensive preoperative assessment and a considerate operative plan should be guaranteed to reduce surgical duration. PMID- 29193654 TI - Technology Experience of Solid Organ Transplant Patients and Their Overall Willingness to Use Interactive Health Technology. AB - BACKGROUND: The use of interactive health technology (IHT) is a promising pathway to tackle self-management problems experienced by many chronically ill patients, including solid organ transplant (Tx) patients. Yet, to ensure that the IHT is accepted and used, a human-centered design process is needed, actively involving end users in all steps of the development process. A first critical, predevelopment step involves understanding end users' characteristics. This study therefore aims to (a) select an IHT platform to deliver a self-management support intervention most closely related to Tx patients' current use of information and communication technologies (ICTs), (b) understand Tx patients' overall willingness to use IHT for self-management support, and investigate associations with relevant technology acceptance variables, and (c) explore Tx patients' views on potential IHT features. DESIGN AND METHODS: We performed a cross-sectional, descriptive study between October and December 2013, enrolling a convenience sample of adult heart, lung, liver, and kidney Tx patients from the University Hospitals Leuven, Belgium. Broad inclusion criteria were applied to ensure a representative patient sample. We used a 35-item newly designed interview questionnaire to measure Tx patients' use of ICTs, their overall willingness to use IHT, and their views on potential IHT features, as well as relevant technology acceptance variables derived from the Unified Theory of Acceptance and Use of Technology and a literature review. Descriptive statistics were used as appropriate, and an ordinal logistic regression model was built to determine the association between Tx patients' overall willingness to use IHT, the selected technology acceptance variables, and patient characteristics. FINDINGS: Out of 139 patients, 122 agreed to participate (32 heart, 30 lung, 30 liver, and 30 kidney Tx patients; participation rate: 88%). Most patients were male (57.4%), married or living together (68%), and had a mean age of 55.9 +/- 13.4 years. Only 27.9% of Tx patients possessed a smartphone, yet 72.1% owned at least one desktop or laptop PC with wireless Internet at home. On a 10-point numeric scale, asking patients whether they think IHT development is important to support them personally in their self-management, patients gave a median score of 7 (25th percentile 5 points; 75th percentile 10 points). Patients who were single or married or living together were more likely to give a higher rating than divorced or widowed patients; patients who completed only secondary education gave a higher rating than higher educated patients; and patients with prior ICT use gave a higher rating than patients without prior ICT use. Tx patients also had clear preferences regarding IHT features, such as automatic data transfer, as much as possible, visual aids (e.g., graphs) over text messages, and personally deciding when to access the IHT. CONCLUSIONS: By investigating Tx patients' possession and use of ICTs, we learned that computers and the Internet, and not smartphones, are the most suitable IHT platforms to deliver self-management interventions for our Tx patients. Moreover, Tx patients generally are open to using IHT, yet patient acceptance variables and their preferences for certain IHT features should be taken into account in the next steps of IHT development. Designers intending to develop or use existing IHTs should never overlook this critical first step in a human-centered design. CLINICAL RELEVANCE: Before considering using eHealth technology in clinical practice, professionals should always check whether patients are familiar with using information and communication technology, and whether they are willing to use technology for health-related purposes. PMID- 29193655 TI - Polygenic risk scores distinguish patients from non-affected adult relatives and from normal controls in schizophrenia and bipolar disorder multi-affected kindreds. AB - Recent studies have used results on SNP association with schizophrenia (SZ) and bipolar disorder (BD) to create polygenic risk scores (PRS) discriminating non familial unrelated patients from controls. Little is known about the role of PRS in densely affected multigenerational families. We tested PRS differences between affected SZ and BD family members from their non-affected adult relatives (NAARs) in Eastern Quebec Kindreds and from controls. We examined 1227 subjects: from 17 SZ and BD kindreds, we studied 153 patients (57 SZ, 13 schizoaffective, and 83 BD) and 180 NAARs, and 894 unrelated controls from the Eastern Quebec population. PRS were derived from published case-control association studies of SZ and BD. We also constructed a combined SZ and BD PRS by using SNPs from both SZ and BD PRS. SZ patients had higher SZ PRS than controls (p = 0.0039, R2 = 0.027) and BD patients had higher BD PRS than controls (p = 0.013, R2 = 0.027). Differences between affected subjects and NAARs and controls were significant with both SZ and BD PRS. Moreover, a combined SZ-BD PRS was also significantly associated with SZ and BD when compared to NAARs (p = 0.0019, R2 = 0.010) and controls (p = 0.0025, R2 = 0.028), revealing a SZ-BD commonality effect in PRS at the diagnosis level. The SZ and the BD PRS, however, showed a degree of specificity regarding thought disorder symptoms. Overall, our report would confirm the usefulness of PRS in capturing the contribution of common genetic variants to the risk of SZ and BD in densely affected families.

AB - This study investigates the microstructure, mechanical properties, corrosion behavior, and biocompatibility of magnesium (Mg)-based Mg1Zr2SrxDy (x = 0, 1, 1.63, 2.08 wt %) alloys for biodegradable implant applications. The corrosion behavior of the Mg-based alloys has been evaluated in simulated body fluid using an electrochemical technique and hydrogen evolution. The biocompatibility of the Mg-based alloys has been assessed using SaSO2 cells. Results indicate that the addition of Dy to Mg-Zr-Sr alloy showed a positive impact on the corrosion behavior and significantly decreased the degradation rates of the alloys. The degradation rate of Mg1Zr2Sr1.0Dy decreased from 17.61 to 12.50 mm year-1 of Mg1Zr2Sr2.08Dy based on the hydrogen evolution. The ultimate compressive strength decreased from 270.90 MPa for Mg1Zr2Sr1Dy to 236.71 MPa for Mg1Zr2Sr2.08Dy. An increase in the addition of Dy to the Mg-based alloys resulted in an increase in the volume fraction of the Mg2 Dy phase, which mitigated the galvanic effect between the Mg17 Sr2 phase and the Mg matrix, and led to an increase in the corrosion resistance of the base alloy. The biocompatibility of the Mg-based alloys was enhanced with decreasing corrosion rates. Mg1Zr2Sr2.08Dy exhibited the lowest corrosion rate and the highest biocompatibility compared with the other Mg based alloys. (c) 2017 Wiley Periodicals, Inc.

PMID- 29193658 TI - Downregulation of dual-specificity tyrosine-regulated kinase 2 promotes tumor cell proliferation and invasion by enhancing cyclin-dependent kinase 14 expression in breast cancer. AB - Tumor progression is the main cause of death in patients with breast cancer. Accumulating evidence suggests that dual-specificity tyrosine-regulated kinase 2 (DYRK2) functions as a tumor suppressor by regulating cell survival, differentiation, proliferation and apoptosis. However, little is known about the mechanisms of transcriptional regulation by DYRK2 in cancer progression, particularly with respect to cancer proliferation and invasion. Here, using a comprehensive expression profiling approach, we show that cyclin-dependent kinase 14 (CDK14) is a target of DYRK2. We found that reduced DYRK2 expression increases CDK14 expression, which promotes cancer cell proliferation and invasion in vitro, in addition to tumorigenicity in vivo. CDK14 and DYRK2 expression inversely correlated in human breast cancer tissues. We further identified androgen receptor (AR) as a candidate of DYRK2-dependent transcription factors regulating CDK14. Taken together, our findings suggest a mechanism by which DYRK2 controls CDK14 expression to regulate tumor cell proliferation and invasion in breast cancer. Targeting of this pathway may be a promising therapeutic strategy for treating breast cancer.

METHODS: Cardiometabolic risk markers were compared in women with prior PTB versus term births; pre-eclampsia and growth restriction cases were excluded. Placental evidence of maternal vascular malperfusion (vasculopathy, infarct, advanced villous maturation, perivillous fibrin, intervillous fibrin deposition), acute infection/inflammation (chorioamnionitis, funisitis, deciduitus) and villitis of unknown aetiology (chronic inflammation) was used to classify PTBs. MAIN OUTCOME MEASURES: Carotid artery intima-media thickness (IMT), fasting lipids, blood pressure (BP) and inflammatory markers measured after delivery. RESULTS: Women with PTB and malperfusion lesions had higher total cholesterol (+13.5 mg/dl) and systolic BP (+4.0 mmHg) at follow up compared with women with term births, accounting for age, race, pre-pregnancy BMI, and smoking (P < 0.05). Women with PTB and malperfusion accompanied by inflammatory lesions had the most atherogenic profile after pregnancy (cholesterol +18.7, apolipoprotein B + 12.7 mg/dl; all P < 0.05), adjusted for pre-pregnancy features. Carotid IMT was higher in this group (+0.037 cm, P = 0.031) accounting for pre-pregnancy factors; differences were attenuated after adjusting for BP and atherogenic lipids at follow up (+0.027, P = 0.095). CONCLUSION: PTBs with placental malperfusion were associated with an excess maternal cardiometabolic risk burden in the decade after pregnancy. The placenta may offer insight into subtypes of PTB related to maternal cardiovascular disease. TWEETABLE ABSTRACT: Preterm births with placental malperfusion may mark women at higher cardiovascular disease risk.

Ascorbic acid (AsA) promotes stress tolerance by scavenging reactive oxygen species (ROS), which accumulate when plants experience abiotic stress. Although the biosynthesis and metabolism of AsA are well established, the genes that regulate these pathways remain largely unexplored. Here, we report on a novel regulatory gene from tomato (Solanum lycopersicum) named SlZF3 that encodes a Cys2/His2-type zinc-finger protein with an EAR repression domain. The expression of SlZF3 was rapidly induced by NaCl treatments. The overexpression of SlZF3 significantly increased the levels of AsA in tomato and Arabidopsis. Consequently, the AsA-mediated ROS scavenging capacity of the SlZF3-overexpressing plants was increased, which enhanced the salt tolerance of these plants. Protein-protein interaction assays demonstrated that SlZF3 directly binds CSN5B, a key component of the COP9 signalosome. This interaction inhibited the binding of CSN5B to VTC1, a GDP mannose pyrophosphorylase that contributes to AsA biosynthesis. We found that the EAR domain promoted the stability of SlZF3 but was not required for the interaction between SlZF3 and CSN5B. Our findings indicate that SlZF3 simultaneously promotes the accumulation of AsA and enhances plant salt-stress tolerance.

AB - BACKGROUND: This study was conducted to evaluate the effects of probiotic supplementation on wound healing and metabolic status in subjects with diabetic foot ulcer (DFU). METHODS: This randomized, double-blind, placebo-controlled trial was conducted among 60 subjects (aged 40-85 years old) with grade 3 diabetic foot ulcer. Individuals were randomly divided into 2 groups (30 subjects each group) to receive either probiotic or placebo daily for 12 weeks. RESULTS: After the 12-week intervention, compared with the placebo, probiotic supplementation led to significant reductions in ulcer length (-1.3 +/- 0.9 vs. 0.8 +/- 0.7 cm, P = .01), width (-1.1 +/- 0.7 vs. -0.7 +/- 0.7 cm, P = .02), and depth (-0.5 +/- 0.3 vs. -0.3 +/- 0.3 cm, P = .02). Furthermore, significant reductions in fasting plasma glucose (-29.6 +/- 30.3 vs. -5.8 +/- 39.8 mg/dL, P = .01), serum insulin concentrations (-4.3 +/- 7.9 vs. +0.4 +/- 8.5 MUIU/mL, P = .03), and haemoglobin A1c (-0.6 +/- 0.5 vs. -0.2 +/- 0.4%, P = .003) and a significant rise in the quantitative insulin sensitivity check index (+0.01 +/- 0.01 vs. -0.01 +/- 0.02, P = .003) were seen following supplementation of probiotic compared with the placebo. Additionally, compared with the placebo, probiotic supplementation resulted in significant decreases in serum total cholesterol (-4.8 +/- 16.1 vs. +7.0 +/- 27.1 mg/dL, P = .04), high-sensitivity C reactive protein (-9.0 +/- 14.7 vs. -1.7 +/- 8.6 mg/L, P = .02), plasma malondialdehyde (-0.8 +/- 0.8 vs. -0.2 +/- 0.8 MUmol/L, P = .001), and significant increases in plasma nitric oxide (+6.2 +/- 8.2 vs. +0.8 +/- 8.0 MUmol/L, P = .01) and total antioxidant capacity concentrations (+179.3 +/- 97.2 vs. -85.1 +/- 203.4 mmol/L, P < .001). CONCLUSIONS: Overall, probiotic supplementation for 12 weeks among subjects with diabetic foot ulcer had beneficial effects on ulcer size, glycaemic control, total cholesterol, high sensitivity C-reactive protein, plasma nitric oxide, total antioxidant capacity, and malondialdehyde levels.

AB - The hereditary spastic paraplegias (HSPs) are a heterogeneous group of disorders characterized by degeneration of the corticospinal and spinocerebellar tracts leading to progressive spasticity. One subtype, spastic paraplegia type 47 (SPG47 or HSP-AP4B1), is due to bi-allelic loss-of-function mutations in the AP4B1 gene. AP4B1 is a subunit of the adapter protein complex 4 (AP-4), a heterotetrameric protein complex that regulates the transport of membrane proteins. Since 2011, 11 individuals from six families with AP4B1 mutations have been reported, nine of whom had homozygous mutations and were from consanguineous families. Here we report eight patients with AP4B1-associated SPG47, the majority born to non consanguineous parents and carrying compound heterozygous mutations. Core clinical features in this cohort and previously published patients include neonatal hypotonia that progresses to spasticity, early onset developmental delay with prominent motor delay and severely impaired or absent speech development, episodes of stereotypic laughter, seizures including frequent febrile seizures, thinning of the corpus callosum, and delayed myelination/white matter loss. Given that some of the features of AP-4 deficiency overlap with those of cerebral palsy, and the discovery of the disorder in non-consanguineous populations, we believe that AP-4 deficiency may be more common than previously appreciated. PMID- 29193664 TI - Genome-wide discovery of tissue-specific miRNAs in clusterbean (Cyamopsis tetragonoloba) indicates their association with galactomannan biosynthesis. AB - Owing to the presence of 80% soluble dietary fibre, high protein content and high value gum, clusterbean (Cyamopsis tetragonoloba) has recently emerged as an economically important legume. The developing clusterbean seeds accumulate 90% galactomannans in the endosperm and, therefore, can be used as a model crop to understand galactomannan biosynthesis and its regulation. miRNAs are tiny master regulators of their corresponding target genes, resulting in variations in the amounts of their metabolic end products. To understand the role of these regulators in galactomannan biosynthesis regulation, small RNA libraries were prepared and sequenced from five tissues of clusterbean genotype RGC-936, and miRanalyzer and DSAP programs were used to identify conserved miRNAs and novel small RNAs. A total of 187 known and 171 novel miRNAs were found to be differentially expressed, of which 10 miRNAs were validated. A complicated network topology and 35% sharing of the target mRNAs between known and novel miRNAs suggest random evolution of novel miRNAs. The gene ontology (GO) annotation of potential target genes revealed the genes coding for signalling and carbohydrate metabolism (50.10%), kinases and other enzymes (20.75%), transcription factors (10.20%), transporters (8.35%) and other targets (10.6%). Two novel unigenes were annotated as ManS (mannosyltransferase/mannan synthase) and UGE (UDP- D-glucose 4-epimerase) and validated as targets for three novel miRNAs, that is Ct-miR3130, Ct-miR3135 and Ct-miR3157. Our findings reveal that these novel miRNAs could play an important role in the regulation of the galactomannan pathway in C. tetragonoloba and possibly other galactomannan producing species. PMID- 29193666 TI - Shifts in air temperature and high-magnitude winter precipitation events in coastal North America: Implications for Environmental Assessment and Management. AB - This commentary examines recent shifts in air temperature data coinciding with high-magnitude precipitation events at climate stations spanning an elevational and longitudinal gradient on the south coast of British Columbia, Canada. Results presented show that high-magnitude winter precipitation events are occurring on British Columbia's south coast under progressively warmer conditions. In the future, proportionally more winter precipitation is anticipated to report as rainfall versus snow, and over time these changes will have a marked impact on the snowmelt-dominated hydrographs that characterize local watersheds. Robust preparedness strategies will be needed to balance competing interests such as the security of domestic water supplies, the permitting and operation of major projects (e.g., mines, hydrodevelopments), and the achievement of broader ecosystem health goals under these changing hydroclimatic conditions.

AB - Storage roots of cassava (Manihot esculenta Crantz), a major subsistence crop of sub-Saharan Africa, are calorie rich but deficient in essential micronutrients, including provitamin A beta-carotene. In this study, beta-carotene concentrations in cassava storage roots were enhanced by co-expression of transgenes for deoxy-d xylulose-5-phosphate synthase (DXS) and bacterial phytoene synthase (crtB), mediated by the patatin-type 1 promoter. Storage roots harvested from field-grown plants accumulated carotenoids to <=50 MUg/g DW, 15- to 20-fold increases relative to roots from nontransgenic plants. Approximately 85%-90% of these carotenoids accumulated as all-trans-beta-carotene, the most nutritionally efficacious carotenoid. beta-Carotene-accumulating storage roots displayed delayed onset of postharvest physiological deterioration, a major constraint limiting utilization of cassava products. Large metabolite changes were detected in beta-carotene-enhanced storage roots. Most significantly, an inverse correlation was observed between beta-carotene and dry matter content, with reductions of 50%-60% of dry matter content in the highest carotenoid accumulating storage roots of different cultivars. Further analysis confirmed a concomitant reduction in starch content and increased levels of total fatty acids, triacylglycerols, soluble sugars and abscisic acid. Potato engineered to co-express DXS and crtB displayed a similar correlation between beta-carotene accumulation, reduced dry matter and starch content and elevated oil and soluble sugars in tubers. Transcriptome analyses revealed a reduced expression of genes involved in starch biosynthesis including ADP-glucose pyrophosphorylase genes in transgenic, carotene-accumulating cassava roots relative to nontransgenic roots. These findings highlight unintended metabolic consequences of provitamin A biofortification of starch-rich organs and point to strategies for redirecting metabolic flux to restore starch production. PMID- 29193667 TI - With adaptation, the WHO guidelines on calcium supplementation for prevention of pre-eclampsia are adopted by pregnant women. AB - The World Health Organization (WHO) recommends calcium supplementation for prevention of pre-eclampsia, but factors affecting adoption and acceptability of the recommendations among pregnant women have not been examined. We explored adoption of the WHO guidelines in Kenya, using the trials of improved practices. We recruited 38 pregnant women and assigned participants to three regimens representing potential trade-offs among daily dose, bioavailability, and acceptability. Participants were provided with supplements, requested to select preferred product type, counselled on how to take them, and interviewed 4 times over 6 weeks to assess their experiences. We tracked bottle opening with electronic monitors, as proxy for supplement consumption. We analysed interview transcripts thematically. All participants were willing to try the supplements. Average daily consumption ranged from 77 to 1,577 mg/d. Most participants (74%) chose the chewable product. Participants preferred its "sweet taste" and liked the ability to consume it without water. Women in the 2-dose regimen were least likely to switch; however, women assigned to the 3-dose regimen, or who switched to the 3-dose regimen, consumed the most calcium per day. Difficulties with the 4 dose regimen included afternoon doses when women were likely to forget and having to wait hours after supper for last dose. Use of an illustrated calendar, keeping supplements in conspicuous locations and requesting support from relatives were strategies that supported adherence. Pregnant women are likely to adopt Ca supplementation, with appropriate programmatic adaptations. Careful attention to product attributes, regimen complexity, and strategies for reassuring and reminding women are needed to adapt the WHO guidelines. PMID- 29193668 TI - Longitudinal study of short-term corticosteroid use by working-age adults with diabetes mellitus: Risks and mitigating factors. AB - BACKGROUND: This study assessed the frequency of short-term oral corticosteroid use in adults with diabetes, examined the incidence of fractures, venous thromboembolism (VTE), and hospitalization for sepsis after corticosteroid use, and evaluated whether preventative medications mitigated adverse events. METHODS: A longitudinal study (2012-14) was conducted of 1 548 945 adults (aged 18-64 years) who received healthcare coverage through a large national health insurer. Incidence rate ratios (IRR) were calculated using conditional Poisson regression. RESULTS: Short-term oral corticosteroids were used by 23.9%, 20.8%, and 20.9% of adults with type 2 diabetes, type 1 diabetes, and no diabetes, respectively, during the 3-year period (P < 0.001). Baseline risks of fracture, VTE, and sepsis were greater for individuals with than without diabetes (P < 0.001). The combined effect of having diabetes and using corticosteroids was greater than the sum of the individual effects (synergy indices of 1.17, 1.23, 1.30 for fracture, VTE, and sepsis, respectively). The IRR for VTE in the 5-30 days after corticosteroid use was 3.62 (95% confidence interval [CI] 2.41-5.45). Fractures increased in the 5-30 days after corticosteroid use (IRR 2.06; 95% CI 1.52, 2.80), but concomitant use of ergocalciferol mitigated this risk (IRR 1.13; 95% CI 0.12, 11.07). The risk of hospitalization for sepsis was elevated with corticosteroid use (IRR 3.79; 95% CI 2.05, 7.01), but was mitigated by the concomitant use of statins. CONCLUSIONS: Short-term oral corticosteroid use is common in adults with diabetes and is associated with an elevated, but low, risk of adverse events. The findings suggest that preventative medications may mitigate risk. PMID- 29193669 TI - Serial lipase for pancreatitis: not enough evidence. AB - BACKGROUND: Lipase is both a sensitive and specific marker for diagnosing pancreatitis. However, the benefit of serial lipase in both monitoring and defining prognosis remains undetermined. This systematic review was conducted to further evaluate this potential application. In addition, this review also looked into the benefits of serial lipase in the subgroup of traumatic pancreatitis. METHODS: PubMed, Cochrane Library and Google Scholar were systematically searched for related articles, between January 1995 and December 2015, according to Preferred Reporting Items for Systematic Reviews and Meta-analyses standards. Data was extracted and analysed by two authors. RESULTS: Seven studies were included in the final analysis: six retrospective and one prospective studies were identified. Five studies (all retrospective) concluded no benefits in serial lipase for prognostication, while two studies identified serial lipase as a beneficial prognostic factor for acute pancreatitis. Of the included studies, only two involved traumatic pancreatitis (both dedicated to the paediatric population). CONCLUSION: The evidence supporting or opposing serial lipase as a prognostic factor for pancreatitis is weak and consists mainly of retrospective analyses. The only prospective data identified suggested benefits to serial lipase in prognosis. Further prospective studies evaluating the prognostic value of serial lipase in the adult population with both traumatic and non-traumatic pancreatitis are required given the paucity of available evidence. PMID- 29193670 TI - Stable Low-Current Electrodeposition of alpha-MnO2 on Superaligned Electrospun Carbon Nanofibers for High-Performance Energy Storage. AB - Metal oxide/carbonaceous nanomaterials are promising candidates for energy storage applications. However, inhomogeneous mass and charge transfer across the electrode/electrolyte interface due to unstable metal oxide/carbonaceous nanomaterial synthesis limit their performance in supercapacitors. Here, it is shown that the above problems can be mitigated through stable low-current electrodeposition of MnO2 on superaligned electrospun carbon nanofibers (ECNFs). The key to this approach is coupling a self-designed four steel poles collector for aligned ECNFs and a constant low-current (40 uA) electrodeposition technique to form a uniform Na+ -induced alpha-MnO2 film which proceeds by a time-dependent growth mechanism involving cluster-"kebab" structures and ending with a compact, uniform MnO2 film for high-performance energy storage. PMID- 29193671 TI - Percutaneous transcatheter pulmonary valve replacement in children weighing less than 20 kg. AB - BACKGROUND: Since FDA approval of the Melody valve, transcatheter pulmonary valve replacement (TPVR) has been offered to an expanding population. Limited data exist regarding the safety and feasibility of TPVR in smaller patients. METHODS: All patients weighing <20 kg who underwent catheterization for percutaneous TPVR at four centers were reviewed. RESULTS: Of the 51 patients reviewed, 43 (84%) had successful valve implantation and 8 (16%) were found not to be candidates due to access veins too small (n = 3), coronary artery/aortic root compression (n = 3), and RVOT too large (n = 2). The 43 patients who underwent successful percutaneous TPVR had a median age and weight of 5.8 years (3.3-10) and 17.7 kg (13.5-19.8), and most had tetralogy of Fallot (TOF). TPVR was performed via femoral vein (FV) access in 24 patients and internal jugular vein (IJV) access in 19 patients. Median weight in patients with IJV implant was 1.1 kg lower than those who underwent transfemoral implant (17.0 vs. 18.1 kg, P = 0.05). There were four adverse events: one iliac vein injury, one contained MPA tear, and two patients with post-procedure femoral vein bleeding. All patients were alive at recent follow-up, a median of 2.0 years (0.1-6.0) after TPVR. There was excellent valve function with mean Doppler gradients of 3-20 mm Hg, and trivial or mild pulmonary regurgitation in all but one patient. There were no RVOT reinterventions and no cases of endocarditis. CONCLUSIONS: Percutaneous TPVR can be safely performed in patients <20 kg. The procedure frequently requires IJV access, and access site/bleeding complications may be more common in this cohort.

PMID- 29193673 TI - Ophthalmic features of cone-rod dystrophy caused by pathogenic variants in the ALMS1 gene. AB - PURPOSE: We aim to describe ophthalmic characteristics and systemic findings in a cohort of seven patients with cone-rod retinal dystrophy (CORD) caused by pathogenic variants in the ALMS1 gene. METHODS: Seven patients with Alstrom syndrome (ALMS) were included in the study. A comprehensive ophthalmological examination was performed, including best-corrected visual acuity (BCVA), a semiautomated kinetic visual field exam, colour vision testing, full-field electroretinography testing according to International Society for Clinical Electrophysiology of Vision (ISCEV) standards, spectral domain optical coherence tomography (SD-OCT) and fundus autofluorescence (FAF) imaging, and slit lamp and dilated fundus examination. DNA samples were analysed using Sanger sequencing or exome sequencing. RESULTS: In our cohort, the ocular phenotype presented with a wide variability in retinal function and disease severity. However, age of symptom onset (i.e. nystagmus and photophobia) was at 6-9 months in all patients. These symptoms mostly mislead to the diagnosis of congenital achromatopsia (ACHM), Leber congenital amaurosis (LCA), isolated CORD or Bardet-Biedl syndrome. The systemic manifestations in our cohort were highly variable. CONCLUSION: In summary, we can report that most of our ALMS patients primarily presented with nystagmus and severe photophobia since early childhood interestingly without night blindness in the absence of systemic symptoms. Only genetic testing analysing both nonsyndromic retinal disease (RD) genes and syndromic ciliopathy genes by comprehensive panel sequencing can result in the correct diagnosis, genetically and clinically, with important implication for the physical health of the individual. PMID- 29193674 TI - Potential Impact of Metabolic and Gut Microbial Response to Pregnancy and Lactation in Lean and Diet-Induced Obese Rats on Offspring Obesity Risk. AB - SCOPE: Maternal obesity programs metabolic dysfunction in offspring, increasing their susceptibility to obesity and metabolic diseases in later life. Moreover, pregnancy and lactation are associated with many metabolic adaptations, yet it is unclear how diet-induced maternal obesity may interrupt these processes. METHODS AND RESULTS: 1 H NMR serum metabolomics analysis was performed on samples collected pre-pregnancy and in pregnant and lactating lean and high fat/sucrose (HFS) diet-induced obese Sprague-Dawley rats to identify maternal metabolic pathways associated with developmental programming of offspring obesity. Gut microbial composition was assessed using qPCR. Offspring of HFS dams had nearly 40% higher adiposity at weaning compared to offspring of lean dams. While pregnancy and lactation were associated with distinct maternal metabolic changes common to both lean and obese dams, we identified several metabolic differences, potentially implicating dysregulated one-carbon and mammary gland metabolism in the metabolic programming of obesity. Gut microbial composition was significantly altered with obesity, and both gestation and lactation were accompanied by changes in gut microbiota. CONCLUSION: Diet-induced maternal obesity and consumption of an obesogenic maternal diet results in differential metabolic and gut microbial adaptations to pregnancy and lactation; these maladaptations may be directly involved in maternal programming of offspring susceptibility to obesity. PMID- 29193675 TI - Gene expression in response to glyphosate treatment in fleabane (Conyza bonariensis) - glyphosate death response and candidate resistance genes. AB - BACKGROUND: This study takes a whole-transcriptome approach to assess gene expression changes in response to glyphosate treatment in glyphosate-resistant fleabane. We assessed gene expression changes in both susceptible and resistant lines so that the glyphosate death response could be quantified, and constitutively expressed candidate resistance genes identified. There are three copies of the glyphosate target site (5-enolpyruvylshikimate-3-phosphate; EPSPS) gene in Conyza and because Conyza bonariensis is allohexaploid, there is a baseline nine copies of the gene in any individual. RESULTS: Many genes were differentially expressed in response to glyphosate treatment. Known resistance mutations are present in EPSPS2 but they are present in a glyphosate-susceptible line as well as resistant lines and therefore not sufficient to confer resistance. EPSPS1 is expressed four times more than EPSPS2, further reducing the overall contribution of these mutations. CONCLUSION: We demonstrate that glyphosate resistance in C. bonariensis is not the result of EPSPS mutations or overexpression, but due to a non-target-site mechanism. A large number of genes are affected by glyphosate treatment. We present a list of candidate non-target site-resistance (NTSR) genes in fleabane for future studies into these mechanisms.

AB - Patients with dry mouth often have an acidic oral environment lacking saliva to provide calcium (Ca) and phosphate (P) ions. There has been no report on tooth remineralization in acidic pH4 and CaP ion-lacking solutions. The objective of this study was to develop a novel method of combining poly(amido amine) (PAMAM) with adhesive containing nanoparticles of amorphous calcium phosphate (NACP) for dentin remineralization in pH4 and CaP-lacking solution for the first time. Demineralized dentin was tested in four groups: (1) dentin control, (2) dentin with PAMAM, (3) dentin with NACP adhesive, (4) dentin with PAMAM + NACP adhesive. Dentin samples were examined by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and hardness testing. Increasing the NACP filler level in adhesive from 0 to 40 wt% did not negatively affect the dentin bond strength (p > 0.1). NACP adhesive released CaP ions and neutralized the acid. PAMAM alone failed to achieve dentin remineralization in lactic acid. NACP alone induced slight dentin remineralization in lactic acid (p > 0.1). In contrast, the novel PAMAM + NACP group in the pH4 and CaP-lacking solution completely remineralized the predemineralized dentin, increasing its hardness which approached that of healthy dentin (p > 0.1). In conclusion, dentin remineralization via PAMAM + NACP adhesive in pH4 and CaP-lacking acid was achieved for the first time, when conventional remineralization methods such as PAMAM or NACP did not work. The novel PAMAM + NACP method is promising to increase the longevity of the composite-tooth bond, inhibit caries, remineralize lesions and protect tooth structures, even for patients with dry mouth and an acidic oral environment.

PMID- 29193677 TI - Gallic Acid Improves Health-Associated Biochemical Parameters and Prevents Oxidative Damage of DNA in Type 2 Diabetes Patients: Results of a Placebo Controlled Pilot Study. AB - SCOPE: Oxidative imbalance plays a key role in cancer induction and cardiovascular diseases (CVD) in patients with type 2 diabetes mellitus (T2DM). The aim of this study is to find out if gallic acid (GA) prevents oxidative stress in diabetic patients. Therefore, we investigate its impact on oxidation of DNA bases and on other health-related macromolecules. METHODS AND RESULTS: We perform an intervention study (n = 19) with GA and monitored alterations of the DNA stability in single cell gel electrophoresis (SCGE) assays in lymphocytes. Furthermore, a panel of health-related biomarkers is measured before and after consumption of GA (15 mg p-1 d-1 ) for 7 d. Significant reduction of oxidized purines (by 31%, p < 0.001, effect size 0.404) and pyrimidines (by 2%, p < 0.022, effect size 0.089) is observed in SCGE assays. Furthermore, the plasma concentrations of oxidized-LDL and C-reactive protein are reduced after the intervention by 24% (p = 0.014, effect size 0.384) and 39% (p < 0.001, effect size 0.686), respectively. No alterations of other biomarkers are found. CONCLUSIONS: A small amount of GA (in the range of daily consumption in Central Europe) prevents oxidative DNA damage and reduces markers which reflect inflammation and increased risks of cancer and CVD. PMID- 29193678 TI - Total Syntheses of Daphenylline, Daphnipaxianine A, and Himalenine D. AB - We report the total syntheses of daphenylline (1), daphnipaxianine A (5), and himalenine D (6), three Daphniphyllum alkaloids from the calyciphylline A subfamily. A pentacyclic triketone was prepared by using atom-transfer radical cyclization and the Lu [3+2] cycloaddition as key steps. Inspired by the proposed biosynthetic relationship between 1 and another calyciphylline A type alkaloid, we developed a ring-expansion/aromatization/aldol cascade to construct the tetrasubstituted benzene moiety of 1. The versatile triketone intermediate was also elaborated into 5 and 6 through a C=C bond migration/aldol cyclization approach. PMID- 29193679 TI - Increased Levels of 27-Hydroxycholesterol Induced by Dietary Cholesterol in Brain Contribute to Learning and Memory Impairment in Rats. AB - SCOPE: Dietary cholesterol has been shown to play a role in the development of Alzheimer's disease (AD). It is proposed that oxysterol especially 27 hydroxycholesterol (27-OHC) may play a potential role in beta-amyloid peptides (Abeta) production and accumulation during AD progression. METHODS AND RESULTS: To investigate the mechanisms of dietary cholesterol and 27-OHC on learning and memory impairment, male Sprague-Dawley rats are fed with cholesterol diet with or without 27-OHC synthetase inhibitor (anastrozole) injection. The levels of cholesterol, 27-OHC, 24-hydroxycholesterol (24S-OHC), 7alpha-hydroxycholesterol, and 7beta-hydroxycholesterol in plasma are determined; apolipoprotein A (ApoA), apolipoprotein B (ApoB), HDL-cholesterol (HDL-C), and LDL-cholesterol (LDL-C) in plasma or brain; CYP27A1 and CYP7A1 in liver and CYP46A1 and CYP7B1 in brain; cathepsin B, cathepsin D, and acid phosphatase in lysosome; and Abeta1-40 and Abeta1-42 in brain. Results show increased levels of 27-OHC (p < 0.01), LDL-C (p < 0.01), and ApoB (p < 0.01), and decreased level of HDL-C (p < 0.05) in plasma, upregulated CYP27A1 (p < 0.01) and CYP7A1 (p < 0.01) expression in liver, altered lysosomal function, and increased level of Abeta in brain (p < 0.05). CONCLUSIONS: This study indicates that the mechanisms of dietary cholesterol on learning and memory impairment may be involved in cholesterol metabolism and lysosome function with the increase of plasma 27-OHC, thus resulting in Abeta formation and accumulation. PMID- 29193680 TI - Larvicidal and residual activity of imidazolium salts against Aedes aegypti (Diptera: Culicidae). AB - BACKGROUND: Aedes aegypti is an important mosquito species that can transmit several arboviruses such as dengue fever, yellow fever, chikungunya and zika. Because these mosquitoes are becoming resistant to most chemical insecticides used around the world, studies with new larvicides should be prioritized. Based on the known biological profile of imidazolium salts (IS), the objective of this study was to evaluate the potential of six IS as larvicides against Ae. aegypti, as tested against Ae. aegypti larvae. Larval mortality was measured after 24 and 48 h, and residual larvicidal activity was also evaluated. RESULTS: Promising results were obtained with aqueous solutions of two IS: 1-n-octadecyl-3 methylimidazolium chloride (C18 MImCl) and 1-n-hexadecyl-3-methylimidazolium methanesulfonate (C16 MImMeS), showing up to 90% larval mortality after 48 h exposure. C18 MImCl was more effective than C16 mIMeS, causing mortality until day 15 after exposure. An application of C18 MImCl left to dry under ambient conditions for at least 2 months and then dissolved in water showed a more pronounced residual effect (36 days with 95% mortality and 80% mortality up to 78 days). CONCLUSION: This is the first study to show the potential of IS in the control of Ae. aegypti. Further studies are needed to understand the mode of action of these compounds in the biological development of this mosquito species. (c) 2017 Society of Chemical Industry. PMID- 29193682 TI - Stretchable and Energy-Efficient Heating Carbon Nanotube Fiber by Designing a Hierarchically Helical Structure. AB - Inspired by the hierarchically helical structure of classical thermal insulation material-wool, a stretchable heating carbon nanotube (CNT) fiber is created with excellent mechanical and heating properties. It can be stretched by up to 150% with high stability and reversibility, and a good thermal insulation is achieved from a large amount of formed hierarchically helical voids inside. Impressively, it exhibits ultrafast thermal response over 1000 degrees C s-1 , low operation voltage of several volts, and high heating stability over 5000 cycles. These hierarchically helical CNT fibers, for the first time, are demonstrated as monofilaments to produce soft and lightweight textiles at a large scale with high heating performances.

Its syndromic nature makes diagnosis and management difficult. The field is rapidly evolving with the definition of pre-eclampsia being challenged by some organisations, with proteinuria no longer being essential in the presence of other features. In the last decade, angiogenic factors, in particular soluble fms-like tyrosine kinase 1 (sFlt-1), have emerged as important molecules in the pathogenesis of pre-eclampsia. Here we review the most recent evidence regarding the potential of these factors as biomarkers and therapeutic targets for pre-eclampsia. TWEETABLE ABSTRACT: A review of angiogenic factors, sFlt-1 and PlGF, in the diagnosis, prediction and management of pre eclampsia. PMID- 29193683 TI - Prognostic value of urinary 11-dehydro-thromboxane B2 for mortality: A cohort study of stable coronary artery disease patients treated with aspirin. AB - AIM: There is a variable cardiovascular risk reduction attributable to aspirin because of individual differences in the suppression of thromboxane A2 and its downstream metabolite 11-dehydro-thromboxane B2 (11dhTxB2 ). The aim of this study is to evaluate the optimal cut point of urinary 11dhTxB2 for the risk of mortality in aspirin-treated coronary artery disease (CAD) patients. METHODS AND RESULTS: This was a prospective cohort study including stable CAD patients who visited the Baylor Heart and Vascular Hospital in Dallas or the Texas Heart Hospital Baylor Plano, TX between 2010 and 2013. The outcome of all-cause mortality was ascertained from chart review and automated sources. The 449 patients included in this analysis had a mean age of 66.1 +/- 10.1 years. 67 (14.9%) patients died within 5 years; 56 (87.5%) of the 64 patients with known cause of death suffered a cardiovascular related mortality. Baseline ln(urinary 11dhTxB2 /creatinine) ranged between 5.8 and 11.1 (median = 7.2) with the higher concentrations among those who died (median: 7.6) than those who survived (median = 7.2, P < 0.001). Using baseline ln(11dhTxB2 ) to predict all-cause mortality, the area under the curve was 0.70 (95% CI: 0.64-0.76). The optimal cut point was found to be ln(7.38) = 1597.8 pg/mg, which had the following decision statistics: sensitivity = 0.67, specificity = 0.62, positive predictive value = 0.24, negative predictive value = 0.92, and accuracy = 0.63. CONCLUSION: Our data indicate the optimal cut point for urine 11dhTxB2 is 1597.8 (pg/mg) for the risk prediction of mortality over five years in stable patients with CAD patients treated with aspirin.

AB - The first example of the OCPPCO ligand, diisophosphaethynolate, is reported via reductive coupling of a Sc-OCP precursor. Upon reduction with KC8 , isolation of the dinuclear complex, namely [K(OEt2 )]2 [(nacnac)Sc(OAr)]2 (OCPPCO), is observed, leading to a unique motif [OCPPCO]4- , stabilized by two scandium centers. Detailed NMR spectra of all complexes as well as IR and single crystal X ray studies were obtained to fully elucidate the nature of these complexes in solution as well as in the solid state. Theory is combined to probe the electronic structure and orbitals responsible for the bonding interactions in the Sc-OCPPCO-Sc skeleton but also to compare to the linear mode observed in the precursor.

AB - Although antiviral drugs are available for the treatment of influenza infection, it is an urgent requirement to develop new antiviral drugs regarding the emergence of drug-resistant viruses. The nucleoprotein (NP) is conserved among all influenza A viruses (IAVs) and has no cellular equivalent. Therefore, NP is an ideal target for the development of new IAV inhibitors. In this study, we identified a novel anti-influenza compound, ZBMD-1, from a library of 20,000 compounds using cell-based influenza A infection assays. We found that ZBMD-1 inhibited the replication of H1N1 and H3N2 influenza A virus strains in vitro, with an IC50 ranging from 0.41-1.14 MUM. Furthermore, ZBMD-1 inhibited the polymerase activity and specifically impaired the nuclear export of NP. Further investigation indicated that ZBMD-1 binds to the nuclear export signal 3 (NES3) domain and the dimer interface of the NP pocket. ZBMD-1 also protected mice that were challenged with lethal doses of A/PR/8/1934 (H1N1) virus, effectively relieving lung histopathology changes, as well as strongly inhibiting the expression of pro-inflammatory cytokines/chemokines, without inducing toxicity effects in mice. These results suggest that ZBMD-1 is a promising anti-influenza compound which can be further investigated as a useful strategy against IAVs in the future.

AB - Poly(lactic acid) (PLA) is one of the most promising renewable and biodegradable polymers for mimic extracellular matrix for tissue engineering applications. In this work, PLA spun membrane scaffold were successfully prepared by air jet spinning technology. Morphology, mechanical properties, in vitro biocompatibility, and in vitro and in vivo degradation of PLA fibrous scaffold were characterized by X-ray diffraction, Fourier Transform Infrared, and scanning electron microscope (SEM). Morphological results assessed by SEM analyses indicated that PLA scaffolds possessed an average fiber diameter of approximately 0.558 +/- 0.141 um for 7% w/v of PLA and approximately 0.647 +/- 0.137 um for 10% w/v. Interestingly, our results showed that the nanofiber size of PLA scaffold allow structural stability after 100 days of in vitro degradation in Ringer solution where the average fiber diameter were of approximately 0.633 +/- 0.147 um for 7% w/v and approximately 0.645 +/- 0.140 um for 10% w/v of PLA. Mechanical properties of PLA fibers scaffold after in vitro degradation showed decrease in terms of flexibility elongation, and less energy was needed to achieve maximal elastic deformation. The fiber size exerts an influence on the biological response of human Bone Marrow Mesenchymal Stromal Cells as confirmed by MTT assay after 9 days of cell culture and the in vivo degradation assay of 7% w/v and 10% w/v of PLA scaffold, did not demonstrate evidence of toxicity with a mild inflammatory respond. In conclusion, airbrushing technology promises to be a viable and attractive alternative technique for producing a biocompatible PLA nanofiber scaffold that could be considered for tissue engineering regeneration.

AB - Tumor metastases are the basic biological characteristics of malignant tumors, and the lungs are the second most prominent metastatic organs in which these develop after the liver. Currently, with the rapid development of ablation technology, ablation therapy as a local treatment is playing an increasingly important role in the treatment of lung metastases. Whether alone or in combination with other treatments, ablation therapy has achieved good therapeutic effects for the treatment of partial lung metastases. This article briefly summarizes the results of current and previous ablation treatments for lung metastases, and focuses on the value of ablation therapy for different kinds of lung metastases. PMID- 29193690 TI - Influenza-associated mortality in Yancheng, China, 2011-15. AB - INTRODUCTION: The Yangtze river delta in eastern China, centered on Shanghai, is one of the most populated regions of the world with more than 100 million residents. We examined the impact of influenza on excess mortality in Yancheng, a prefecture-level city with 8.2 million population located 250 km north of Shanghai, during 2011-2015. METHODS: We obtained individual data on deaths by date, age, sex, and cause in Yancheng from the Chinese Centers for Disease Control and Prevention, and used these to derive weekly rates of mortality from respiratory causes, respiratory and cardiovascular causes combined, and all causes. We used data on influenza-like illnesses and laboratory detections of influenza to construct a proxy measure of the weekly incidence of influenza virus infections in the community. We used regression models to estimate the association of influenza activity with mortality and excess mortality by age, cause, and influenza type/subtype. RESULTS: We estimated that an annual average of 4.59 (95% confidence interval: 3.94, 7.41) excess respiratory deaths per 100 000 persons were associated with influenza, which was 4.6% of all respiratory deaths in the years studied. Almost all influenza-associated excess deaths occurred in persons >=65 years. Influenza A(H3N2) had the greatest impact on mortality and was associated with around 50% of the influenza-associated respiratory deaths in the 5 years studied. CONCLUSIONS: Influenza has a substantial impact on respiratory mortality in Yancheng, mainly in older adults. Influenza vaccination has the potential to reduce disease burden, and cost effectiveness analysis could be used to compare policy options. PMID- 29193691 TI - Purple Potato Extract Promotes Intestinal Epithelial Differentiation and Barrier Function by Activating AMP-Activated Protein Kinase. AB - SCOPE: Perturbation of gut epithelial barrier function induces inflammation and other health problems that originate from the gut. Purple potato contains a high content of beneficial polyphenolic compounds. The objective of this study is to evaluate the effect of purple potato extract (PPE) on intestinal differentiation and barrier function, and explore its underlying mechanism using Caco-2 cells and ex vivo cultured gut tissues. METHODS AND RESULTS: PPE increases transepithelial electrical resistance and decreases FITC-dextran paracellular flux in Caco-2 cells, which are associated with strengthened intestinal epithelial differentiation in both Caco-2 cells and ex vivo guts. Furthermore, PPE treatment enhances AMP-activated protein kinase (AMPK) activity, concomitant with the increased expression of CDX2, a key transcriptional factor regulating intestinal epithelial differentiation. Knocking out AMPK using CRISPR/Cas9 system abolishes the positive effects of PPE on intestinal epithelial differentiation and barrier function, in junction with the reduced expression of CDX2. CONCLUSION: PPE improves gut epithelial differentiation and barrier function via activating AMPK, indicating that PPE, as well as associated purple potato consumption, could be used as a supportive dietary therapeutic strategy for improving gut epithelial health. PMID- 29193689 TI - Negative regulators of platelet activation and adhesion. AB - Platelets are small anucleated cells that constantly patrol the cardiovascular system to preserve its integrity and prevent excessive blood loss where the vessel lining is breached. Their key challenge is to form a hemostatic plug under conditions of high shear forces. To do so, platelets have evolved a molecular machinery that enables them to sense trace amounts of signals at the site of damage and to rapidly shift from a non-adhesive to a pro-adhesive state. However, this highly efficient molecular machinery can also lead to unintended platelet activation and cause clinical complications such as thrombocytopenia and thrombosis. Thus, several checkpoints are in place to tightly control platelet activation and adhesiveness in space and time. In this review, we will discuss select negative regulators of platelet activation, which are critical to maintain patrolling platelets in a quiescent, non-adhesive state and/or to limit platelet adhesion to sites of injury. PMID- 29193692 TI - Impact of African traditional worldviews on climate change adaptation. AB - Recent studies show cultural worldviews are a key determinant of environmental risk perceptions; thus, they could influence climate change adaptation strategies. African traditional worldviews encourage harmony between humans and the environment through a complex metaphysical belief system transmitted through folklore, taboos, and traditional knowledge. However, African traditional worldviews hold a belief in traditional gods that was shown to have a low connectedness to nature and a low willingness to change. In Makueni District, Kenya, 45% of agropastoralists surveyed believed drought was god's plan and could not be changed. In contrast, traditional knowledge, which is shaped by African traditional worldviews, is often used to frame adaptive strategies such as migration, changing modes of production, and planting different crop varieties. Furthermore, traditional knowledge has been used as a complement to science in areas where meteorological data was unavailable. However, the role of African traditional worldviews on climate change adaption remains understudied. Hence, there is a need to systematically establish the influence of African traditional worldviews on climate change risk perception, development of adaptive strategies, and policy formulation and implementation. In this commentary, we discuss the potential impacts of African traditional worldviews on climate change adaptation. Integr Environ Assess Manag 2018;14:189-193. (c) 2018 SETAC. PMID- 29193694 TI - Association between diabetes and mortality in elderly patients admitted for a first episode of acute heart failure. AB - AIM: To examine whether the presence of a prior diagnosis of diabetes mellitus (DM) influences mortality risk in elderly patients experiencing a first episode of heart failure (HF) hospitalization. METHODS: A total of 677 consecutive patients aged >=75 years admitted for a first episode of acute decompensated heart failure were evaluated according to the presence or not of DM, and in hospital and 1-year mortality rates were evaluated. RESULTS: A total of 240 patients (35.4%) had a diagnosis of DM. Overall, 42 patients (6.2%) died during admission; and 205 patients (30.3%) died after 1 year; however, no differences were observed in mortality rates between both groups. Cox univariate analysis did not identify prior DM diagnosis as a risk factor for 1-year mortality (HR 0.767, P < 0.082). Multivariate analysis identified older age (HR 1.101, P < 0.0001), lower preadmission Barthel Index (HR 0.987, P = 0.002), higher heart rate (HR 1.013, P = 0.02), higher admission serum potassium (HR 1.471, P = 0.016) and non prescription of angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists (HR 1.597, P = 0.018) as independent risk factors for 1-year mortality. CONCLUSIONS: More than one-third of elderly patients experiencing a first admission because of acute heart failure decompensation had a prior diagnosis of DM. However, DM did not seem to be associated to a significant 1 year mortality risk. Geriatr Gerontol Int 2018; 18: 554-560. PMID- 29193695 TI - Climate conditions, and changes, affect microalgae communities... should we worry? AB - Microalgae play a pivotal role in the regulation of Earth's climate and its cycles, but are also affected by climate change, mainly by changes in temperature, light, ocean acidification, water stratification, and precipitation induced nutrient inputs. The changes and impacts on microalgae communities are difficult to study, predict, and manage, but there is no doubt that there will be changes. These changes will have impacts beyond microalgae communities, and many of them will be negative. Some actions are currently ongoing for the mitigation of some of the negative impacts, such as harmful algal blooms and water quality, but global efforts for reducing CO2 emissions, temperature rises, and ocean acidification are paramount for reducing the impact of climate change on microalgae communities, and eventually, on human well-being.

AB - Nondividing cancer cells are relatively resistant to chemotherapeutic drugs and environmental stress factors. Promoting cell cycle re-entry of quiescent cancer cells is a potential strategy to enhance the cytotoxicity of agents that target cycling cells. It is therefore important to elucidate the mechanisms by which these cells are maintained in the quiescent state. The protein kinase dual specificity tyrosine phosphorylation-regulated kinase 1B (DYRK1B) is overexpressed in a subset of cancers and maintains cellular quiescence by counteracting G0 /G1 -S phase transition. Specifically, DYRK1B controls the S phase checkpoint by stabilizing the cyclin-dependent kinase (CDK) inhibitor p27Kip1 and inducing the degradation of cyclin D. DYRK1B also stabilizes the DREAM complex that represses cell cycle gene expression in G0 arrested cells. In addition, DYRK1B enhances cell survival by upregulating antioxidant gene expression and reducing intracellular levels of reactive oxygen species (ROS). Substantial evidence indicates that depletion or inhibition of DYRK1B drives cell cycle re-entry and enhances apoptosis of those quiescent cancer cells with high expression of DYRK1B. Furthermore, small molecule DYRK1B inhibitors sensitize cells to the cytotoxic effects of anticancer drugs that target proliferating cells. These encouraging findings justify continued efforts to investigate the use of DYRK1B inhibitors to disrupt the quiescent state and overturn chemoresistance of noncycling cancer cells.

AB - PURPOSE: This study investigated the staff nurses' perception of the infection prevention climate and its predictors in two hospitals. DESIGN: This is a cross sectional study employing a convenience sample of 224 staff nurses at two general hospitals in Riyadh province. METHODS: The study utilized a two-part questionnaire that captures respondents' characteristics and the validated tool on Leading a Culture of Quality for Infection Prevention (LCQ-IP). Both descriptive and inferential statistics were utilized accordingly. RESULTS: The prioritization of quality received the highest mean score among the four factors of the scale (mean = 3.89, SD = 0.65), followed by supportive work environment (mean = 3.88, SD = 0.68), psychological safety (mean = 3.85, SD = 0.65), and improvement orientation (mean = 3.84, SD = 0.64). Nationality, clinical experience, and attendance to seminars or training were identified as significant predictors. CONCLUSIONS: The respondents perceived the infection prevention climate of the two general hospitals positively. This study strengthens the idea that organizational context influences negatively or positively the programs on infection prevention being implemented in the hospitals. CLINICAL RELEVANCE: The result may facilitate nursing and hospital management to reflect, examine, and review their organizational climate, the impact of infection prevention initiatives and patient safety strategies, and the reason to amend related policies or improve procedures, including the promotion of a healthy work environment. PMID- 29193702 TI - Role of anterior segment optical coherence tomography in angle-closure disease: a review. AB - This article aims to review the published literature pertaining to the use of anterior segment optical coherence tomography (AS-OCT) in the evaluation of angle closure disease. Searches on the available published literature were last conducted on 15 June 2017. Rated as Level I evidence, we found that AS-OCT has shown good sensitivity and moderate diagnostic accuracy to detect narrow angles when compared with gonioscopy. AS-OCT quantitative and qualitative parameters demonstrated strong association with the presence of gonioscopically closed angles. This technology provides an objective non-contact method of assessing the angle that is well tolerated by the patient and correlates well with the information provided by gonioscopy. PMID- 29193703 TI - Inflammation and thrombosis: roles of neutrophils, platelets and endothelial cells and their interactions in thrombus formation during sepsis. AB - The inflammatory response and the activation of coagulation are two important responses in a host's defense against infection. These mechanisms do not work independently, but cooperate in a complex and synchronous manner. Recent research has also shed light on the critical role of thrombus formation, which prevents the dissemination of microorganisms. The cellular components of blood vessels, i.e. leukocytes, platelets, erythrocytes, and vascular endothelial cells, play significant roles in the development of thrombi in combination with activation of the coagulation system. In addition to the cellular components, alarmins such as histones and high-mobility group box 1, microparticles and secreted granule proteins are all important for clot formation. In this summary, we review the pathophysiology of sepsis-induced coagulopathy and the role of cellular components and critical factors released from damaged cells. In addition, we review important therapeutic approaches that have been developed, are under investigation and are currently available in certain countries, including antithrombin, recombinant thrombomodulin, anti-Toll-like receptor 4 therapy, anti damage associated molecular pattern therapy, and hemoadsorption with a polymyxin B-immobilized fiber column.

AB - Calcium-dependent protein kinases (CPKs) are serine/threonine protein kinases that function in plant stress responses. Although CPKs are recognized as key messengers in signal transduction, the specific roles of CPKs and the molecular mechanisms underlying their activity remain largely unknown. Here, we characterized the function of OsCPK24, a cytosol-localized calcium-dependent protein kinase in rice. OsCPK24 was universally and highly expressed in rice plants and was induced by cold treatment. Whereas OsCPK24 knockdown plants exhibited increased sensitivity to cold compared to wild type (WT), OsCPK24 overexpressing plants exhibited increased cold tolerance. Plants overexpressing OsCPK24 exhibited increased accumulation of proline (an osmoprotectant) and glutathione (an antioxidant) and maintained a higher GSH/GSSG (reduced glutathione to oxidized glutathione) ratio during cold stress compared to WT. In addition to these effects in response to cold stress, we observed the kinase activity of OsCPK24 varied under different calcium concentrations. Further, OsCPK24 phosphorylated OsGrx10, a glutathione-dependent thioltransferase, at rates modulated by changes in calcium concentration. Together, our results support the hypothesis that OsCPK24 functions as a positive regulator of cold stress tolerance in rice, a process mediated by calcium signaling and involving phosphorylation and the inhibition of OsGrx10 to sustain higher glutathione levels.

AB - INTRODUCTION: This study investigated the efficacy of scopolamine (an anticholinergic agent) ointment against clozapine-induced hypersalivation. METHODS: The patients enrolled in this study consisted of 10 clozapine-treated schizophrenia patients and 10 healthy adult men. A prospective, randomized, double-blind, crossover, placebo-controlled clinical trial was designed. RESULTS: A total of 10 patients and 10 healthy adult men completed the study. No significant reduction in the saliva production of the clozapine-treated patients was observed; however, that of the healthy adult men decreased significantly. DISCUSSION: Scopolamine ointment was not effective against clozapine-induced hypersalivation. A further study is necessary for confirming its effect.

AB - INTRODUCTION: To investigate whether early improvement can predict 8-week treatment outcome in generalized anxiety disorder (GAD) patients. METHODS: For 8 weeks, 226 GAD patients were randomly treated with escitalopram or venlafaxine. Early improvement was defined as a ?20% reduction from baseline in Hamilton anxiety rating scale at week 1 or 2. The positive and negative predictive values were calculated. RESULTS: The positive and negative predictive values of early improvement in escitalopram or venlafaxine group at week 1 were (85.19%, 67.53%) vs (84.62%, 65.33%) DISCUSSION: The early improvement achieved within the first week treatment can predict a good 8-week treatment outcome in GAD patients.

AB - Carbon nanodots (CNDs) were synthesized using low-cost and biocompatible starting materials such as citric acid/urea, under microwave irradiation, and constant pressure conditions. The obtained pressure-synthesized CNDs (pCNDs) were covalently modified with photo- and electroactive pi-extended tetrathiafulvalene (exTTF) by means of a two-step esterification reaction, affording pCND-exTTF. The electronic interactions between the pCNDs and exTTF were investigated in the ground and excited states. Ultrafast pump-probe experiments assisted in corroborating that charge separation governs the deactivation of photoexcited pCND-exTTF. These size-regular structures, as revealed by AFM, are stable electron donor-acceptor conjugates of interest for a better understanding of basic processes such as artificial photosynthesis, catalysis, and photovoltaics, involving readily available fluorescent nanodots. PMID- 29193717 TI - Is venous blood gas performed in the Emergency Department predictive of outcome during acute on chronic hypercarbic respiratory failure? AB - BACKGROUND: During acute on chronic hypercarbic respiratory failure (AHRF), arterial pH is associated with non-invasive ventilation (NIV) failure and mortality. Venous blood gas (VBG) has been proposed as a substitute for arterial blood gas, based on a good agreement between venous and arterial values. We assessed the predictive value of admission VBG on intubation rate, NIV failure and mortality during AHRF. METHODS: Retrospective chart review of inpatients admitted between 2009 and 2015 with AHRF who had VBG performed on admission. Demographic, clinical and biological data were collected throughout the hospital course. RESULTS: 196 patients were included and hospital survival was not significantly associated with initial venous pH, PCO2 or HCO3-. Patients requiring intubation had significantly lower venous pH [7.29 (7.24-7.33) vs 7.31 (7.28-7.36), P = .04] while venous PCO2 and HCO3- did not differ as compared to non-intubated patients. Intubation within 48 h of admission was associated with significantly lower venous pH [7.28 (7.24-7.30) vs 7.32 (7.28-7.37), P = .002] and higher PCO2 [72 (63-92) mm Hg vs 62 (52-75) mm Hg, P = .04]. Among 69 patients receiving NIV, there were no differences in venous pH [7.29 (7.25-7.31) vs 7.30 (7.27-7.35), P = .3] or PCO2 [68 (44-74) mm Hg vs 70 (55-97) mm Hg, P = .23] associated with subsequent intubation. Using c statistics, we observed poor performances of venous pH, PCO2 or HCO3- for prediction of NIV failure, intubation or hospital mortality. CONCLUSIONS: Our results do not support the use of VBG on admission as a predictor for NIV failure, intubation and mortality during AHRF. PMID- 29193716 TI - Acute inhibition of PMCA4, but not global ablation, reduces blood pressure and arterial contractility via a nNOS-dependent mechanism. AB - Cardiovascular disease is the world's leading cause of morbidity and mortality, with high blood pressure (BP) contributing to increased severity and number of adverse outcomes. Plasma membrane calcium ATPase 4 (PMCA4) has been previously shown to modulate systemic BP. However, published data are conflicting, with both overexpression and inhibition of PMCA4 in vivo shown to increase arterial contractility. Hence, our objective was to determine the role of PMCA4 in the regulation of BP and to further understand how PMCA4 functionally regulates BP using a novel specific inhibitor to PMCA4, aurintricarboxylic acid (ATA). Our approach assessed conscious BP and contractility of resistance arteries from PMCA4 global knockout (PMCA4KO) mice compared to wild-type animals. Global ablation of PMCA4 had no significant effect on BP, arterial structure or isolated arterial contractility. ATA treatment significantly reduced BP and arterial contractility in wild-type mice but had no significant effect in PMCA4KO mice. The effect of ATAin vivo and ex vivo was abolished by the neuronal nitric oxide synthase (nNOS) inhibitor Vinyl-l-NIO. Thus, this highlights differences in the effects of PMCA4 ablation and acute inhibition on the vasculature. Importantly, for doses here used, we show the vascular effects of ATA to be specific for PMCA4 and that ATA may be a further experimental tool for elucidating the role of PMCA4.

AB - AIM: With an aging Singapore population, there is an increasing demand for dementia care. The present study aimed to evaluate the effectiveness and cost effectiveness of the Primary Care Dementia Clinic (PCDC) in comparison with the Memory Clinic (MC; hospital-based) and other polyclinics. METHODS: A quasi experimental design was implemented. Effectiveness of PCDC was assessed through caregiver satisfaction, quality of life (caregiver-rated) and adverse events rates. Quality-of-Life measures using the EuroQol 5 Dimension Questionnaire (EQ 5D) at baseline, 6 months and 12 months was assessed. Costs were calculated from a societal perspective. The incremental cost-effectiveness of the PCDC was compared with MC and other polyclinics. RESULTS: The present study showed that quality of life and the rate of adverse events at 12 months were similar between the three groups. Caregiver satisfaction at 12 months was higher in the PCDC group when compared with other polyclinics. There were no observed differences in societal cost between the three groups. At 6-month follow up, direct medical costs for PCDC were significantly lower that of other polyclinics. At 12-month follow up, PCDC patients had higher Quality Adjusted Life Years (QALYs) compared with the MC group. CONCLUSION: PCDC provided effective care, similar to care at MC and better than care at other polyclinics. Caregiver satisfaction was higher for the PCDC group, and PCDC patients had lower direct medical costs at 6-month follow up. Given these findings, adopting a PCDC model in other polyclinics in Singapore can be beneficial for optimal right siting of patients. Geriatr Gerontol Int 2018; 18: 479-486. PMID- 29193722 TI - F2 screen, inheritance and cross-resistance of field-derived Vip3A resistance in Spodoptera frugiperda (Lepidoptera: Noctuidae) collected from Louisiana, USA. AB - BACKGROUND: Fall armyworm, Spodoptera frugiperda, is a target pest of the Vip3A protein used in pyramided Bt corn and cotton in the USA. In this study, we provide the first documentation of a resistance allele conferring Vip3A resistance in a field-derived population of S. frugiperda from the USA, and characterize its inheritance and cross-resistance. RESULTS: An F2 screen with 104 two-parent families generated from a field collection of S. frugiperda in Louisiana, USA, resulted in one family carrying a Vip3A resistance allele. The Vip3A-resistant strain (RR) derived from the two-parent family showed a high level of resistance to Vip3A in both diet and whole-plant bioassays, with a resistance ratio of >632.0-fold relative to a susceptible population (SS) based on diet-overlay bioassays. The inheritance of Vip3A resistance was monogenic, autosomal and recessive. Furthermore, the Vip3A resistance conferred no cross resistance to Cry1F, Cry2Ab2 or Cry2Ae purified proteins, with resistance ratios of 3.5, 5.0 and 1.1, respectively. CONCLUSION: These findings provide valuable information for characterizing Vip3A resistance, resistance monitoring, and developing effective resistance management strategies for the sustainable use of the Vip3A technology.

PMID- 29193723 TI - TRAF6 regulates tumour metastasis through EMT and CSC phenotypes in head and neck squamous cell carcinoma. AB - Epithelial-mesenchymal transition (EMT) is associated with metastasis formation, generation and maintenance of cancer stem cells (CSCs). However, the regulatory mechanisms of CSCs have not been clarified. This study aims to investigate the role of TNF receptor-associated factor 6 (TRAF6) on EMT and CSC regulation in squamous cell carcinoma of head and neck (SCCHN). We found TRAF6 was overexpressed in human SCCHN tissues, and high TRAF6 expression was associated with lymphatic metastasis and resulted in poor prognosis in patients with SCCHN. In addition, elevated TRAF6 expression was observed in several HNSCC cell lines, and wound healing and transwell assay results showed that TRAF6 knockdown inhibited the migration and invasion ability of the SCCHN cells. Moreover, the expression of Vimentin, Slug and N-cadherin was down-regulated and that of E cadherin was elevated after TRAF6 knockdown but decreased by transforming growth factor beta 1 (TGF-beta1) and CAL27 similar to mesenchymal cells formed after TGF beta1 induction. In addition, the expression levels of CD44, ALDH1, KLF4 and SOX2 were inhibited after TRAF6 knockdown, and the anchor-dependent colony formation number and sphere number were remarkably reduced. Flow cytometry showed TRAF6 knockdown reduced ALDH1-positive cancer stem cells. We also demonstrated that TRAF6 is closely associated with EMT process and cancer stem cells using a Tgfbr1/Pten 2cKO mice SCCHN model and human SCCHN tissue microarray. Our findings indicate that TRAF6 plays a role in EMT phenotypes, the generation and maintenance of CSCs in SCCHN, suggesting that TRAF6 is a potential therapeutic target for SCCHN.

AB - The opportunity to target weed seeds during grain harvest was established many decades ago following the introduction of mechanical harvesting and the recognition of high weed-seed retention levels at crop maturity; however, this opportunity remained largely neglected until more recently. The introduction and adoption of harvest weed seed control (HWSC) systems in Australia has been in response to widespread occurrence of herbicide-resistant weed populations. With diminishing herbicide resources and the need to maintain highly productive reduced tillage and stubble-retention practices, growers began to develop systems that targeted weed seeds during crop harvest. Research and development efforts over the past two decades have established the efficacy of HWSC systems in Australian cropping systems, where widespread adoption is now occurring. With similarly dramatic herbicide resistance issues now present across many of the world's cropping regions, it is timely for HWSC systems to be considered for inclusion in weed-management programs in these areas. This review describes HWSC systems and establishing the potential for this approach to weed control in several cropping regions. As observed in Australia, the inclusion of HWSC systems can reduce weed populations substantially reducing the potential for weed adaptation and resistance evolution.

AB - The antimalarial agent dihydroartemisinin (DHA) has been shown to be anti inflammatory. In this study, we found that DHA increased the expression of the junctional protein vascular endothelial (VE)-cadherin in human renal glomerular endothelial cells. In addition, DHA inhibited TGF-beta RI-Smad2/3 signalling and its downstream effectors SNAIL and SLUG, which repress VE-cadherin gene transcription. Correspondingly, DHA decreased the binding of SNAIL and SLUG to the VE-cadherin promoter. Together, our results suggest an effect of DHA in regulating glomerular permeability by elevation of VE-cadherin expression. PMID- 29193727 TI - General and Facile Route to Isomerically Pure Tricyclic Peptides Based on Templated Tandem CLIPS/CuAAC Cyclizations. AB - We report a one-pot ligation/cyclization technology for the rapid and clean conversion of linear peptides into tricyclic peptides that is based on using tetravalent scaffolds containing two benzyl bromide and two alkyne moieties. These react via CLIPS/CuAAC reactions with cysteines and azides in the peptide. Flexibility in the scaffolds is key to the formation of isomerically pure products as the flexible scaffolds T41 and T42 mostly promote the formation of single isomeric tricycles while the rigid scaffolds T43 and T44 do not yield clean products. There seems to be no limitation to the number and types of amino acids present as 18 canonical amino acids were successfully implemented. We also observed that azides at the peptide termini and cysteine residues in the center gave better results than compounds with the functional groups placed the other way round.

AB - beta-Catenin signalling plays an important role in regulating tubular epithelial to-mesenchymal transition (EMT), an indispensable programme for driving renal fibrosis. As an adapter protein, four and a half LIM domain protein 2 (FHL2) acts as a coregulator of beta-catenin in several other cell types. To determine whether FHL2 affects beta-catenin signalling and thus is involved in tubular EMT, we examined its expression and function in the process of TGF-beta1-induced EMT. FHL2 mRNA and protein were induced by TGF-beta1 in rat tubular epithelial cells (NRK-52E), an effect that intracellular Smad signalling was required. Ectopic expression of FHL2 inhibited E-cadherin and enhanced alpha-smooth muscle actin (alpha-SMA) and fibronectin expression, whereas knockdown of FHL2 partially restored E-cadherin and reduced alpha-SMA and fibronectin induction stimulated by TGF-beta1. Overexpression of FHL2 increased beta-catenin dephosphorylation (Ser37/Thr41), nuclear translocation and beta-catenin-mediated transcription and up-regulated expression of beta-catenin target, EMT-related genes, such as Snail, Twist, vimentin, plasminogen activator inhibitor-1 and matrix metalloproteinase 7. Conversely, knockdown of FHL2 increased beta-catenin phosphorylation (Ser33/37/Thr41), decreased its nuclear translocation and inhibited beta-catenin mediated transcription and target genes expression. TGF-beta1 induced a FHL2/beta catenin interaction in NRK-52E cells, especially in the nuclei. In a mouse model of obstructive nephropathy, FHL2 mRNA and protein were induced in a time dependent fashion, and the extent and pattern of renal beta-catenin activation were positively correlated with FHL2 induction. Collectively, this study suggests that FHL2, via modulating beta-catenin signalling, may implicate in regulation of TGF-beta1-mediated tubular EMT and could be a potential therapeutic target for fibrotic kidney disease.

PMID- 29193730 TI - The 3p14.2 tumour suppressor ADAMTS9 is inactivated by promoter CpG methylation and inhibits tumour cell growth in breast cancer. AB - Chromosome region 3p12-14 is an important tumour suppressor gene (TSG) locus for multiple cancers. ADAMTS9, a member of the metalloprotease large family, has been identified as a candidate 3p14.2 TSG inactivated by aberrant promoter CpG methylation in several carcinomas, but little known about its expression and function in breast cancer. In this report, ADAMTS9 expression and methylation was analysed in breast cancer cell lines and tissue samples. ADAMTS9 RNA was significantly down-regulated in breast cancer cell lines (6/8). After treating the cells with demethylation agent Aza and TSA, ADAMTS9 expression was dramatically increased. Bisulphite genomic sequencing and methylation-specific PCR detected promoter methylation, which was associated with decreased ADAMTS9 expression. Hypermethylation was also detected in 130/219 (59.4%) of primary tumours but only in 4.5% (2/44) of paired surgical margin tissues. Ectopic expression of ADAMTS9 in tumor cells induced significant growth suppression, cell cycle arrest at the G0/G1 phase, enhanced apoptosis and reduced cell migration and invasion. Conditioned culture medium from ADAMTS9-transfected BT549 cells markedly disrupted tube formation ability of human umbilical vein endothelial cell (HUVEC) in Matrigel. Furthermore, ADAMTS9 inhibited AKT signaling and its downstream targets (MDM2, p53, p21, p27, E-cadherin, VIM, SNAIL, VEGFA, NFkappaB p65 and MMP2). In addition, we demonstrated, for the first time, that ADAMTS9 inhibits AKT signaling, through suppressing its upstream activators EGFR and TGFbeta1/TbetaR(I/II) in breast cancer cells. Our results suggest that ADAMTS9 is a TSG epigenetically inactivated in breast cancer, which functions through blocking EGFR- and TGFbeta1/TbetaR(I/II)-activated AKT signaling.

AB - AIM: Strengthening neighborhood social networks is important for promoting health among older adults. However, effective intervention strategies aimed at increasing older adults' social networks have not yet been established. The present study examined whether a university-led community intervention that provided communication opportunities could increase older Japanese adults' neighborhood social networks. METHODS: The present study used a quasi experimental design. Before the intervention, using postal mail, we carried out a baseline questionnaire survey that was sent to all people living in the Tsurukabuto community aged >=60 years (n = 1769), of whom 1068 responded. For the community intervention, 18 event-based programs were provided over the course of 1 year at Kobe University. Academic staff at Kobe University organized all the programs. During the program, social interactions among participants were promoted. A follow-up survey was distributed to those who responded to the baseline survey, and 710 individuals answered the question about their participation in the intervention programs (138 respondents were participants, 572 were non-participants). The neighborhood social network was measured in both the baseline and follow-up surveys. RESULTS: Analysis of covariance showed that the changes in neighborhood social network among participants in the program was significantly higher than the changes among non-participants (P = 0.046) after adjusting for the baseline score of social network. CONCLUSIONS: The present study found that participants of the intervention expanded their neighborhood social network, but non-participants did not. This finding shows that community interventions using university resources could increase older adults' neighborhood social networks. Geriatr Gerontol Int 2018; 18: 462-469. PMID- 29193733 TI - Overexpression of the class I homeodomain transcription factor TaHDZipI-5 increases drought and frost tolerance in transgenic wheat. AB - Characterization of the function of stress-related genes helps to understand the mechanisms of plant responses to environmental conditions. The findings of this work defined the role of the wheat TaHDZipI-5 gene, encoding a stress-responsive homeodomain-leucine zipper class I (HD-Zip I) transcription factor, during the development of plant tolerance to frost and drought. Strong induction of TaHDZipI 5 expression by low temperatures, and the elevated TaHDZipI-5 levels of expression in flowers and early developing grains in the absence of stress, suggests that TaHDZipI-5 is involved in the regulation of frost tolerance at flowering. The TaHDZipI-5 protein behaved as an activator in a yeast transactivation assay, and the TaHDZipI-5 activation domain was localized to its C-terminus. The TaHDZipI-5 protein homo- and hetero-dimerizes with related TaHDZipI-3, and differences between DNA interactions in both dimers were specified at 3D molecular levels. The constitutive overexpression of TaHDZipI-5 in bread wheat significantly enhanced frost and drought tolerance of transgenic wheat lines with the appearance of undesired phenotypic features, which included a reduced plant size and biomass, delayed flowering and a grain yield decrease. An attempt to improve the phenotype of transgenic wheat by the application of stress-inducible promoters with contrasting properties did not lead to the elimination of undesired phenotype, apparently due to strict spatial requirements for TaHDZipI-5 overexpression. PMID- 29193735 TI - Shotgun label-free proteomic analysis for identification of proteins in HaCaT human skin keratinocytes regulated by the administration of collagen from soft shelled turtle. AB - Soft-shelled turtles (Pelodiscus sinensis) are widely distributed in some Asian countries, and we previously reported that soft-shelled turtle tissue could be a useful material for collagen. In the present study, we performed shotgun liquid chromatography (LC)/mass spectrometry (MS)-based global proteomic analysis of collagen-administered human keratinocytes to examine the functional effects of collagen from soft-shelled turtle on human skin. Using a semiquantitative method based on spectral counting, we were able to successfully identify 187 proteins with expression levels that were changed more than twofold by the administration of collagen from soft-shelled turtle. Based on Gene Ontology analysis, the functions of these proteins closely correlated with cell-cell adhesion. In addition, epithelial-mesenchymal transition was induced by the administration of collagen from soft-shelled turtle through the down-regulation of E-cadherin expression. Moreover, collagen-administered keratinocytes significantly facilitated wound healing compared with nontreated cells in an in vitro scratch wound healing assay. These findings suggest that collagen from soft-shelled turtle provides significant benefits for skin wound healing and may be a useful material for pharmaceuticals and medical care products.

AB - Click to hear Dr Baglin's perspective on the role of the laboratory in treatment with new oral anticoagulants SUMMARY: One of the key benefits of the direct oral anticoagulants (DOACs) is that they do not require routine laboratory monitoring. Nevertheless, assessment of DOAC exposure and anticoagulant effects may become useful in various clinical scenarios. The five approved DOACs (apixaban, betrixaban, dabigatran etexilate, edoxaban and rivaroxaban) have different characteristics impacting assay selection and the interpretation of results. This article provides an updated overview on (i) which test to use (and their advantages and limitations), (ii) when to assay DOAC levels, (iii) how to interpret the results relating to bleeding risk, emergency situations and perioperative management, and (iv) what is the impact of DOACs on routine and specialized coagulation assays. Assays for anti-Xa or anti-IIa activity are the preferred methods when quantitative information is useful, although the situations in which to test for DOAC levels are still debated. Different reagent sensitivities and variabilities in laboratory calibrations impact assay results. International calibration standards for all specific tests for each DOAC are needed to reduce the inter-laboratory variability and allow inter-study comparisons. The impact of the DOACs on hemostasis testing may cause false positive or false-negative results; however, these can be minimized by using specific assays and collecting blood samples at trough concentrations. Finally, prospective clinical trials are needed to validate the safety and efficacy of proposed laboratory thresholds in relation to clinical decisions. We offer recommendations on the tests to use for measuring DOACs and practical guidance on laboratory testing to help patient management and avoid diagnostic errors. PMID- 29193736 TI - Development of interstitial cells of Cajal in the human digestive tract as the result of reciprocal induction of mesenchymal and neural crest cells. AB - Neural crest cells (NCC) can migrate into different parts of the body and express their strong inductive potential. In addition, they are multipotent and are able to differentiate into various cell types with diverse functions. In the primitive gut, NCC induce differentiation of muscular structures and interstitial cells of Cajal (ICC), and they themselves differentiate into the elements of the enteric nervous system (ENS), neurons and glial cells. ICC develop by way of mesenchymal cell differentiation in the outer parts of the primitive gut wall around the myenteric plexus (MP) ganglia, with the exception of colon, where they appear simultaneously also at the submucosal border of the circular muscular layer around the submucosal plexus (SMP) ganglia. However, in a complex process of reciprocal induction of NCC and local mesenchyma, c-kit positive precursors are the first to differentiate, representing probably the common precursors of ICC and smooth muscle cells (SMC). C-kit positive precursors could represent a key impact factor regarding the final differentiation of NCC into neurons and glial cells with neurons subsequently excreting stem cell factor (SCF) and other signalling molecules. Under the impact of SCF, a portion of c-kit positive precursors lying immediately around the ganglia differentiate into ICC, while the rest differentiate into SMC. PMID- 29193738 TI - Cooperative role of the glucagon-like peptide-1 receptor and beta3-adrenergic mediated signalling on fat mass reduction through the downregulation of PKA/AKT/AMPK signalling in the adipose tissue and muscle of rats. AB - AIM: To explore the cooperation of GLP-1 receptor and beta3-adrenergic receptor (beta3-AR)-mediated signalling in the control of fat mass/feeding behaviour by studying the effects of a combined therapy composed of the GLP-1R agonist liraglutide and the beta3-AR agonist CL316243. METHODS: The study included the analysis of key mechanisms regulating lipid/cholesterol metabolism, and thermogenesis in brown (BAT) and epididymal white (eWAT) adipose tissues, abdominal muscle and liver of male rats. RESULTS: CL316243 (1 mg kg-1 ) and liraglutide (100 MUg kg-1 ) co-administration over 6 days potentiated an overall negative energy balance (reduction in food intake, body weight gain, fat/non-fat mass ratio, liver fat content, and circulating levels of non-essential fatty acids, triglycerides, very low-density lipoprotein-cholesterol and leptin). These effects were accompanied by increased plasma levels of insulin and IL6. We also observed increased gene expression of uncoupling proteins regulating thermogenesis in BAT/eWAT (Ucp1) and muscle (Ucp2/3). Expression of transcription factor and enzymes involved either in de novo lipogenesis (Chrebp, Acaca, Fasn, Scd1, Insig1, Srebp1) or in fatty acid beta-oxidation (Cpt1b) was enhanced in eWAT and/or muscle but decreased in BAT. Pparalpha and Ppargamma, essentials in lipid flux/storage, were decreased in BAT/eWAT but increased in the muscle and liver. Cholesterol synthesis regulators (Insig2, Srebp2, Hmgcr) were particularly over-expressed in muscle. These GLP-1R/beta3-AR-induced metabolic effects were associated with the downregulation of cAMP-dependent signalling pathways (PKA/AKT/AMPK). CONCLUSION: Combined activation of GLP-1 and beta3-ARs potentiate changes in peripheral pathways regulating lipid/cholesterol metabolism in a tissue-specific manner that favours a switch in energy availability/expenditure and may be useful for obesity treatment.

AB - BACKGROUND: While the 'no-tillage' management system generally improves soil properties and helps to control arthropod pests, it may also intensify crop infestation by the common vole (Microtus arvalis Pallas). In this study, we evaluated the impact of soil management (no-tillage or tillage), crop and previous crop (winter wheat or winter rape), and season (spring or autumn) on common vole density using data from the Common Vole Monitoring Programme undertaken by the Plant Protection Service of the Czech Republic between 2000 and 2009. RESULTS: Models predicted low mean values of vole infestation across management types, crops, and seasons. The untilled fields hosted significantly more voles than the tilled fields in spring but not in autumn. More common voles were found in winter rape than in winter wheat during both seasons. CONCLUSION: Recent studies suggest that no-tillage management is more profitable than tillage management as a result of its positive impact on soil properties and pest control. During periods of high vole infestation, however, tillage may constitute an alternative strategy for reducing yield losses. (c) 2017 Society of Chemical Industry. PMID- 29193740 TI - Viral internal ribosomal entry sites: four classes for one goal. AB - To ensure efficient propagation, viruses need to rapidly produce viral proteins after cell entrance. Since viral genomes do not encode any components of the protein biosynthesis machinery, viral proteins must be produced by the host cell. To hi-jack the host cellular translation, viruses use a great variety of distinct strategies. Many single-stranded positive-sensed RNA viruses contain so-called internal ribosome entry sites (IRESs). IRESs are structural RNA motifs that have evolved to specific folds that recruit the host ribosomes on the viral coding sequences in order to synthesize viral proteins. In host canonical translation, recruitment of the translation machinery components is essentially guided by the 5' cap (m7 G) of mRNA. In contrast, IRESs are able to promote efficient ribosome assembly internally and in cap-independent manner. IRESs have been categorized into four classes, based on their length, nucleotide sequence, secondary and tertiary structures, as well as their mode of action. Classes I and II require the assistance of cellular auxiliary factors, the eukaryotic intiation factors (eIF), for efficient ribosome assembly. Class III IRESs require only a subset of eIFs whereas Class IV, which are the more compact, can promote translation without any eIFs. Extensive functional and structural investigations of IRESs over the past decades have allowed a better understanding of their mode of action for viral translation. Because viral translation has a pivotal role in the infectious program, IRESs are therefore attractive targets for therapeutic purposes.

PMID- 29193742 TI - Development of a LC-MS/MS method for the determination of isomeric glutamyl peptides in food ingredients. AB - A liquid chromatography with tandem mass spectrometry method was developed for the determination of 27 glutamyl di- and tripeptides in food ingredients. Such compounds are of importance for the food industry, as they can modulate the perception of basic tastes (sweet, salty, and umami). Due to their high polarity, the hydrophilic interaction chromatography mode was selected to have sufficient retention on the column and the best separation was obtained on an amide hybrid silica stationary phase packed with 1.7 MUm particles. Thorough optimization of the mobile phase was performed as the start-composition had to be free of ammonium to avoid on-column cis-trans isomerization of the first eluting proline dipeptide. A baseline separation was achieved for all alpha and gamma isomers whereas only a partial resolution was obtained for gamma-Glu-Leu and gamma-Glu Ile, for which only the position of a methyl group differs. A fast sample preparation, based on successive dilutions, was performed before injection into the liquid chromatography with tandem mass spectrometry system. The developed method was then applied for the semi-quantification of glutamyl di- and tri peptides in four different food ingredients. The methodology will further support the optimization of production processes to select the conditions for which the peptide concentrations would be the highest. PMID- 29193741 TI - Energy Expenditure and Hormone Responses in Humans After Overeating High-Fructose Corn Syrup Versus Whole-Wheat Foods. AB - OBJECTIVE: This study sought to understand how the dietary source of carbohydrates, either high-fructose corn syrup (HFCS) or complex carbohydrates, affects energy expenditure (EE) measures, appetitive sensations, and hormones during 24 hours of overfeeding. METHODS: Seventeen healthy participants with normal glucose regulation had 24-hour EE measures and fasting blood and 24-hour urine collection during four different 1-day diets, including an energy-balanced diet, fasting, and two 75% carbohydrate diets (5% fat) given at 200% of energy requirements with either HFCS or whole-wheat foods as the carbohydrate source. In eight volunteers, hunger was assessed with visual analog scales the morning after the diets. RESULTS: Compared with energy balance, 24-hour EE increased 12.8% +/- 6.9% with carbohydrate overfeeding (P < 0.0001). No differences in 24-hour EE or macronutrient utilization were observed between the two high-carbohydrate diets; however, sleeping metabolic rate was higher after the HFCS diet (Delta = 35 +/- 48 kcal [146 +/- 200 kJ]; P = 0.01). Insulin, ghrelin, and triglycerides increased the morning after both overfeeding diets. Urinary cortisol concentrations (82.8 +/- 35.9 vs. 107.6 +/- 46.9 nmol/24 h; P = 0.01) and morning after hunger scores (Delta = 2.4 +/- 2.0 cm; P = 0.01) were higher with HFCS overfeeding. CONCLUSIONS: The dietary carbohydrate source while overeating did not affect 24-hour EE, but HFCS overconsumption may predispose individuals to further overeating due to increased glucocorticoid release and increased hunger the following morning. PMID- 29193743 TI - Development of a fidelity scale for Danish specialized early interventions service. AB - BACKGROUND: The efficacy of the Specialized Early Intervention (SEI) treatment in Denmark, the OPUS treatment, has in a randomized clinical trial proved to be very effective compared to treatment as usual, and the dissemination of SEI services is increasing in Denmark. A prerequisite for upholding positive effects along with creating new teams and preserving critical components is to ensure fidelity to the model. Currently there is no Danish fidelity scale for SEI services. AIM: To establish a fidelity scale for SEI teams, in a brief and easily manageable form, for the use of evaluating and assessing the critical components in Danish SEI services. METHOD: We identified essential evidence-based components of SEI services internationally and interviewed experts from five Danish SEI teams, using an adapted version of the Delphi Consensus method. RESULTS: An 18-point fidelity scale was constructed. The scale was divided into two dimensions: one relating to the structure of the SEI team and one relating to the character and content of the SEI treatment. Each component can be rated either 1 or 0 (1 point = fulfilling the requirements for the components; and 0 point = the requirements were not met). The maximum score was a total of 18 points with 5 of the components being mandatory. CONCLUSION: The development of the fidelity scale is an important tool for securing the quality of SEI treatment in Denmark.

AB - Supermarkets have been described as having unprecedented and disproportionate power in the food system. This scoping review synthesized the literature that describes the position and power of supermarkets in the Australian food system, and the implications for public health. A systematic search of peer-reviewed and grey literature identified 68 documents that described supermarket power. Implications for public health were also recorded. Data revealed that supermarkets hold a powerful position in the Australian food system, acting as the primary gatekeepers. Supermarkets have obtained instrumental, structural and discursive power from many sources that overlap and reinforce each other. Few positive public health impacts of supermarket power were identified, providing many opportunities for improvement in the domains of food governance, the food system and public health nutrition. There is very little public health research examining the impact of supermarket power in Australia. More research is needed, and examination of supermarket own brands is of particular importance owing to their pivotal role as a source of power and their potential to improve public health outcomes, such as obesity. PMID- 29193745 TI - United States news media and climate change in the era of US President Trump. AB - The Donald J Trump administration's strategy to disengage and downplay the Paris Climate Agreement will likely result in a slight decrease in the already low levels of US news media global warming coverage. This is because significant limitations with the news media's ability to adequately cover climate change predated the administration. First, studies indicate that advertising interests and editors have always challenged journalists' abilities to adequately report on climate change issues. Instead of climate change stories, editors often prefer more sensational topics that garner higher ratings and approval with advertisers. Second, the journalistic norm of balance and the role of sourcing give climate skeptics exceptional media exposure, which creates a "false balance" or equivalency between skeptics and scientists. Third, the massive power and influence of the fossil fuel industry's public relations arm has also had a tremendous impact on public (mis)understanding of climate change. Fourth, a trend toward declining climate change coverage and "climate silence" in US media is developing. Media corporations have substantially eliminated the number of environmental journalists that cover climate change. The overall effect of these limitations distorts public understanding of climate change and delays potential government action. Moving away from a predominantly commercial media system to one with a substantial noncommercial component can improve US journalism, whereas using advertising to increase rates for environmentally unsound products and services may also help mitigate global warming.

AB - Microbial infections continually present a major worldwide public healthcare threat, particularly in instances of impaired wound healing and biomedical implant fouling. The development of new materials with the desired antimicrobial property to avoid and treat wound infection is urgently needed in wound care management. This study reports a novel dual-functional biodegradable dextran poly(ethylene glycol) (PEG) hydrogel covalently conjugated with antibacterial Polymyxin B and Vancomycin (Vanco). The hydrogel is designed as a specialized wound dressing that eradicates existing bacteria and inhibits further bacteria growth, while, ameliorating the side effects of antibiotics and accelerating tissue repair and regeneration. The hydrogel exhibits potent antibacterial activities against both gram-negative bacteria Escherichia coli (E. coli) and gram-positive bacteria Staphylococcus aureus (S. aureus) with no observable toxicity to mouse fibroblast cell line NIH 3T3. These results demonstrate the immense potential of dextran-PEG hydrogel as a wound dressing healthcare material in efficiently controlling bacteria growth in complex biological systems.

This study was conducted to establish the bioequivalence of a new cherry-flavored mini lozenge with that of a currently marketed mint-flavored mini lozenge. The rate (Cmax ) and extent (AUC0-t ) of plasma nicotine absorption were compared after administration of 2- and 4-mg doses of each lozenge in healthy adult smokers (n = 43). The bioequivalence of each respective dose was established based on the 90% confidence interval for the ratio of geometric means for both Cmax and AUC0-t lying within the range of 0.80 to 1.25. Adverse-event profiles were similar between formulations. PMID- 29193748 TI - Modulation of cell responses to Ag-(MeO2 MA-co-OEGMA): Effects of nanoparticle surface hydrophobicity and serum proteins on cellular uptake and toxicity. AB - Nanoparticle (NP) interactions with cellular systems are influenced by both NP physico-chemical properties and the presence of surface-bound proteins that are adsorbed in biological environments. Here, we characterize cellular responses to silver nanoparticles (AgNPs) functionalized with poly(di(ethylene glycol) methyl ether methacrylate-co-oligo(ethylene glycol) methyl methacrylate) (poly(MeO2 MAx co-OEGMAy )) brushes with tunable hydrophobicity and explore how these responses are modulated by the presence or absence of serum proteins. Poly(MeO2 MAx -co OEGMAy ) with variable composition (5-10% OEGMA) was fabricated to elicit differential hydrophobicity at 37 degrees C for AgNPs capped with these copolymers. The increase in Ag-(MeO2 MAx -co-OEGMAy ) surface hydrophobicity from (x:y) = 90:10 to (x:y) = 95:5 led to enhanced cytotoxicity of L-929 fibroblasts and a concomitant increase in cell uptake and reactive oxygen species generation in the presence of serum proteins. These responses were attenuated significantly in serum-free environments. Broad inhibition of PI3 kinase-mediated endocytosis reduced both cell uptake and cytotoxicity in the presence or absence of serum proteins. In contrast, selective inhibition of clathrin- and caveolae-mediated endocytosis markedly decreased cell uptake and cytotoxicity in response to Ag (MeO2 MA95 -co-OEGMA5 ) exclusively in the presence of serum proteins, whereas cell responses to the more hydrophilic Ag-(MeO2 MA90 -co-OEGMA10 ) were less affected by the inhibition of these pathways with or without serum proteins. This study demonstrates an important role for both NP surface hydrophobicity and the presence of serum proteins in directing cell uptake and subsequent cellular responses, which we suggest has broad application in the design of polymer functionalized NPs for specific biological outcomes.

The S enantiomer was baseline resolved from its R impurity (impurity C) with a mobile phase consisting of methanol/water (100:15) without any interference coming from the other two potential chiral impurities A and B. The enantio- and chemoselective method was partially validated and compared with that reported in the United States Pharmacopoeia for the drug product. The versatility of the Chiralcel OJ-RH allowed separating the enantiomers of the impurity B also under normal phase and setting up an efficient strategy to convert the racemic sample into the enantiomeric S form on a semipreparative scale.

AB - In 2014, we established a pharmacogenetics unit with the intention of facilitating the integration of pharmacogenetic testing into clinical practice. This unit was centered around two main ideas: i) individualization of clinical recommendations, and ii) preemptive genotyping in risk populations. Our unit is based on the design and validation of a single nucleotide polymorphism (SNP) microarray, which has allowed testing of 180 SNPs associated with drug response (PharmArray), and clinical consultation regarding the results. Herein, we report our experience in integrating pharmacogenetic testing into our hospital and we present the results of the 2,539 pharmacogenetic consultation requests received over the past 3 years in our unit. The results demonstrate the feasibility of implementing pharmacogenetic testing in clinical practice within a national health system. PMID- 29193752 TI - The Proteomic Response of Bacillus pumilus Cells to Glucose Starvation. AB - Since starvation for carbon sources is a common condition for bacteria in nature and it can also occur in industrial fermentation processes due to mixing zones, knowledge about the response of cells to carbon starvation is beneficial. The preferred carbon source for bacilli is glucose. The response of Bacillus pumilus cells to glucose starvation using metabolic labeling and quantitative proteomics was analyzed. Glucose starvation led to an extensive reprogramming of the protein expression pattern in B. pumilus. The amounts of proteins of the central carbon metabolic pathways (glycolysis and TCC) remained stable in starving cells. Proteins for gluconeogenesis were found in higher amounts during starvation. Furthermore, many proteins involved in acquisition and usage of alternative carbon sources were present in elevated amounts in starving cells. Enzymes for fatty acid degradation and proteases and peptidases were also found in higher abundance when cells entered stationary phase. Among the proteins found in lower amounts were many enzymes involved in amino acid and nucleotide synthesis and several NRPS and PKS proteins.

AB - OBJECTIVES: The aim of the Hybrid Video Registry (HVR) is to assess the acute safety and efficacy of the Hybrid Approach in comparison to other contemporary methods of CTO-PCI. BACKGROUND: Recently, multiple techniques in Percutaneous Coronary Intervention (PCI) for coronary Chronic Total Occlusions (CTO) have been synthesized into a method referred to as the "Hybrid Approach". METHODS: About 194 video-taped timed live cases from CTO-PCI training workshops were analyzed by independent data abstractors and compared to three contemporary CTO-PCI registries stratified by case complexity based on the J-CTO score. RESULTS: Overall procedural success was 95% of all cases attempted with an excellent safety profile. In the most complex lesion subset, which made up 45% of all HVR cases, success was 92.8%, which was significantly higher than either the Royal Bromptom (78.9%), or Japanese-CTO (73.3%) registries, P = 0.04 Hybrid vs. Royal Brompton, P = 0.006 Hybrid vs. Japanese-CTO). The Hybrid Approach was also associated with shorter procedure times and lower contrast utilization. CONCLUSIONS: In a real world angiographic registry of complex CTOs, the Hybrid Approach to CTO-PCI is safe, and may be superior to other contemporary approaches to CTO intervention with respect to procedural success and efficiency among a diverse group of operators and lesion complexity.

AB - A novel technique that integrates extraction and clean-up into a single step format is reported as part of the search for new sample preparation techniques in the analysis of persistent organic pollutants from complex samples. This was achieved by combining the extraction efficiency of the Soxhlet extractor, the selectivity of a size exclusion membrane and the specificity of a molecularly imprinted polymer for the extraction of polycyclic aromatic hydrocarbons from wastewater sludge followed by quantitation using gas chromatography with time-of flight mass spectrometry. The approach is described as the Soxhlet extraction membrane-assisted solvent extraction molecularly imprinted polymer technique. This technique was optimised for various parameters such as extraction solvent, reflux time and membrane acceptor phase. The applicability of the developed technique was optimised using a wastewater sludge certified reference material and then tested on real wastewater sludge samples. The method detection limits ranged from 0.14 to 12.86 ng/g with relative standard deviation values for the extraction of the 16 US-EPA priority polycyclic aromatic hydrocarbons from wastewater sludge samples ranging from 0.78 to 18%. The extraction process was therefore reproducible and showed remarkable selectivity. The developed technique is a promising prospect that can be applied in the analysis of organic pollutants from complex solid samples. PMID- 29193751 TI - The triune of intestinal microbiome, genetics and inflammatory status and its impact on the healing of lower gastrointestinal anastomoses. AB - Gastrointestinal resections are a common operation and most involve an anastomosis to rejoin the ends of the remaining bowel to restore gastrointestinal (GIT) continuity. While most joins heal uneventfully, in up to 26% of patients healing fails and an anastomotic leak (AL) develops. Despite advances in surgical technology and techniques, the rate of anastomotic leaks has not decreased over the last few decades raising the possibility that perhaps we do not yet fully understand the phenomenon of AL and are thus ill-equipped to prevent it. As in all complex conditions, it is necessary to isolate each different aspect of disease for interrogation of its specific role, but, as we hope to demonstrate in this article, it is a dangerous oversimplification to consider any single aspect as the full answer to the problem. Instead, consideration of important individual observations in parallel could illuminate the way forward towards a possibly simple solution amidst the complexity. This article details three aspects that we believe intertwine, and therefore should be considered together in wound healing within the GIT during postsurgical recovery: the microbiome, the host genetic make-up and their relationship to the perioperative inflammatory status. Each of these, alone or in combination, has been linked with various states of health and disease, and in combining these three aspects in the case of postoperative recovery from bowel resection, we may be nearer an answer to preventing anastomotic leaks than might have been thought just a few years ago. PMID- 29193755 TI - Relationship between kidney findings and systemic vascular damage in elderly hypertensive patients without overt cardiovascular disease. AB - Few studies have investigated the influence of age on the relationships between systemic vascular damage, kidney dysfunction, and intrarenal hemodynamic changes in patients with hypertension without overt cardiovascular disease. The authors enrolled 126 elderly patients with hypertension (aged >=65 years) and 350 nonelderly patients with hypertension (aged <65 years). Carotid intima-media thickness, renal resistive index, and aortic pulse wave velocity were performed in all patients. Elderly patients with hypertension had lower estimated glomerular filtration rates and higher albuminuria, renal resistive index, carotid intima-media thickness, and aortic pulse wave velocity compared with nonelderly patients with hypertension (P < .001). Carotid intima-media thickness independently correlated with renal resistive index and estimated glomerular filtration rate in nonelderly patients with hypertension, whereas it was significantly related to renal resistive index only in elderly patients with hypertension. Aortic pulse wave velocity was independently associated with albuminuria in nonelderly patients with hypertension, whereas it did not independently correlate with any indexes of renal damage in elderly patients with hypertension. Age is an important modifier of the relationships between renal function and renal hemodynamics with subclinical vascular involvement in elderly persons without cardiovascular disease. PMID- 29193756 TI - Investigating the cardiac pathology of SCO2-mediated hypertrophic cardiomyopathy using patients induced pluripotent stem cell-derived cardiomyocytes. AB - Mutations in SCO2 are among the most common causes of COX deficiency, resulting in reduced mitochondrial oxidative ATP production capacity, often leading to hypertrophic cardiomyopathy (HCM). To date, none of the recent pertaining reports provide deep understanding of the SCO2 disease pathophysiology. To investigate the cardiac pathology of the disease, we were the first to generate induced pluripotent stem cell (iPSC)-derived cardiomyocytes (iPSC-CMs) from SCO2-mutated patients. For iPSC generation, we reprogrammed skin fibroblasts from two SCO2 patients and healthy controls. The first patient was a compound heterozygote to the common E140K mutation, and the second was homozygote for the less common G193S mutation. iPSC were differentiated into cardiomyocytes through embryoid body (EB) formation. To test the hypothesis that the SCO2 mutation is associated with mitochondrial abnormalities, and intracellular Ca2+ -overload resulting in functional derangements and arrhythmias, we investigated in SCO2-mutated iPSC-CMs (compared to control cardiomyocytes): (i) the ultrastructural changes; (ii) the inotropic responsiveness to beta-adrenergic stimulation, increased [Ca2+ ]o and angiotensin-II (AT-II); and (iii) the Beat Rate Variability (BRV) characteristics. In support of the hypothesis, we found in the mutated iPSC-CMs major ultrastructural abnormalities and markedly attenuated response to the inotropic interventions and caffeine, as well as delayed afterdepolarizations (DADs) and increased BRV, suggesting impaired SR Ca2+ handling due to attenuated SERCA activity caused by ATP shortage. Our novel results show that iPSC-CMs are useful for investigating the pathophysiological mechanisms underlying the SCO2 mutation syndrome. PMID- 29193757 TI - Effects of the Consumption of Milk Biofortified with Selenium, Vitamin E, and Different Fatty Acid Profile on Immune Response in the Elderly. AB - SCOPE: Nutrition is a major contributing factor for immunocompetence. The aim was to assess the immune status of older people after consuming milk produced by lactating cows fed with one of the following diets: control diet (C), C + vitamin E + selenium (C + A), C + sunflower oil (C + O), and C + sunflower oil + vitamin E + selenium (A + O). METHODS AND RESULTS: Sixty elderly people received one of these biofortified milks for 12 weeks. Immune response was assessed by measurement of the expression of COX-1, COX-2, MCP-1, PPAR (delta, alpha, and beta/delta) genes, neutrophil production of oxygen reactive species induced by immune complexes, neutrophil phagocytosis and lytic activity of the alternative pathway of the complement system, and cytokine levels. Variables were assessed before and after treatment. Our findings showed stability of some inflammatory mediators (complement activity and neutrophils burst) in treatment groups, except complement activity in C + A, and an increase of these markers in C, especially reactive oxygen species production and phagocytic activity. TNF-alpha was significantly increased in all groups. In C + A, IL-4 and IL-2 increased after treatment, and in the group that received the milk produced by cows fed with "O" diet, CCL20 and IL-27 increased. CONCLUSION: Overall, as compared to C, milk biofortification was associated with stabilization of the activity of alternative complement pathway and the neutrophils burst, and modulated different cytokines levels. PMID- 29193758 TI - Hemodynamic impact of pulmonary vasodilators on single ventricle physiology. AB - INTRODUCTION: The Fontan procedure is the palliative procedure for single ventricle physiology. Pulmonary resistance plays a key role in the success of this operation. There are conflicting data concerning the impact of pulmonary vasodilators on survival and functional capacity among Fontan patients. AIM: The aim of this retrospective, single-center, nonrandomized study was to investigate the potential effect of pulmonary vasodilators on pulmonary vasculature in Fontan patients. METHOD: Twenty-seven patients with single ventricle physiology were enrolled. Eighteen patients were treated with pulmonary vasodilators: 9 patients after Glenn procedure or just after the Fontan completion (Group A) and 9 patients >5 years after Fontan completion (Group B). Nine patients after Glenn procedure were enrolled as a control group (Group C). The primary endpoint was to assess changes in hemodynamic profile and pulmonary branches' diameter after 2 right heart catheterizations. Adverse events were recorded. RESULTS: Mean age +/- SD was 3.2 +/- 1.5 years (Group A), 26.8 +/- 12.7 years (Group B), and 3.1 +/- 1.0 years (Group C). Patients included in Group A had reduced arterial compliance (34.3 +/- 15.4 vs 52.2 +/- 24.2 mm2 /[m2 *mm Hg]; P = .03) at baseline compared with Group C. After treatment, Nakata index and pulmonary compliance increased in patients treated with pulmonary vasodilators (Group A), while remaining stable in the control group (Nakata index: +26 +/- 24% vs -8 +/- 17%, P = .003; pulmonary compliance +80 +/- 49% vs -5 +/- 30%, P = .001). Similar results were found in Group B (Nakata index: pre-168.6 +/- 70.7 mm2 /m2 ; post-204.9 +/- 97.5 mm2 /m2 ; P = .026). CONCLUSIONS: Pulmonary vasodilators reduce pulmonary artery resistance and increase vascular compliance, pulmonary artery diameter, and cardiac output in Fontan patients. Therefore, pulmonary vasodilators may be used before the Fontan procedure in patients at high risk of Fontan procedure failure. PMID- 29193759 TI - Soil and Water Assessment Tool model predictions of annual maximum pesticide concentrations in high vulnerability watersheds. AB - Recent national regulatory assessments of potential pesticide exposure of threatened and endangered species in aquatic habitats have led to increased need for watershed-scale predictions of pesticide concentrations in flowing water bodies. This study was conducted to assess the ability of the uncalibrated Soil and Water Assessment Tool (SWAT) to predict annual maximum pesticide concentrations in the flowing water bodies of highly vulnerable small- to medium sized watersheds. The SWAT was applied to 27 watersheds, largely within the midwest corn belt of the United States, ranging from 20 to 386 km2 , and evaluated using consistent input data sets and an uncalibrated parameterization approach. The watersheds were selected from the Atrazine Ecological Exposure Monitoring Program and the Heidelberg Tributary Loading Program, both of which contain high temporal resolution atrazine sampling data from watersheds with exceptionally high vulnerability to atrazine exposure. The model performance was assessed based upon predictions of annual maximum atrazine concentrations in 1-d and 60-d durations, predictions critical in pesticide-threatened and endangered species risk assessments when evaluating potential acute and chronic exposure to aquatic organisms. The simulation results showed that for nearly half of the watersheds simulated, the uncalibrated SWAT model was able to predict annual maximum pesticide concentrations within a narrow range of uncertainty resulting from atrazine application timing patterns. An uncalibrated model's predictive performance is essential for the assessment of pesticide exposure in flowing water bodies, the majority of which have insufficient monitoring data for direct calibration, even in data-rich countries. In situations in which SWAT over- or underpredicted the annual maximum concentrations, the magnitude of the over- or underprediction was commonly less than a factor of 2, indicating that the model and uncalibrated parameterization approach provide a capable method for predicting the aquatic exposure required to support pesticide regulatory decision making.

AB - AIM: To identify the measles vaccination status of nurses, their knowledge and health beliefs about measles, and the associated factors that influence their measles vaccination status during a community measles outbreak in South Korea. METHODS: The participants were 156 nurses from four hospitals in a region where a community measles outbreak occurred. RESULTS: The measles vaccination rate of the nurses was 73.7%. The nurses' health belief score about measles was 2.44 out of 4 and their knowledge score was 73.85 out of 100. The associated factors that influenced the nurses' measles vaccination status included their experience of caring for patients with measles and a low level of perceived barriers to vaccination. CONCLUSION: In order to encourage an increased measles vaccination rate in nurses, hospitals should screen susceptible nurses and offer vaccination. Effective measles vaccination campaigns and educational programs are also required in hospitals.

AB - Using dual-photoelectrode photoelectrochemical (PEC) devices based on earth abundant metal oxides for unbiased water splitting is an attractive means of producing green H2 fuel, but is challenging, owing to low photovoltages generated by PEC cells. This problem can be solved by coupling n-type BiVO4 with n-type Bi4 V2 O11 to create a virtual p/n junction due to the formation of a hole-inversion layer at the semiconductor interface. Thus, photoelectrodes with high photovoltage outputs were synthesized. The photoelectrodes exhibited features of p- and n-type semiconductors when illuminated under an applied bias, suggesting their use as photoanode and photocathode in a dual-photoelectrode PEC cell. This concept was proved by connecting a 1 mol % W-doped BiVO4 /Bi4 V2 O11 photoanode with an undoped BiVO4 /Bi4 V2 O11 photocathode, which produced a high photovoltage of 1.54 V, sufficient to drive stand-alone water splitting with 0.95 % efficiency.

AB - The photoelectrochemical (PEC) carbon dioxide reduction process stands out as a promising avenue for the conversion of solar energy into chemical feedstocks, among various methods available for carbon dioxide mitigation. Semiconductors derived from cheap and abundant elements are interesting candidates for catalysis. Whether employed as intrinsic semiconductors or hybridized with metallic cocatalysts, biocatalysts, and metal molecular complexes, semiconductor photocathodes exhibit good performance and low overpotential during carbon dioxide reduction. Apart from focusing on carbon dioxide reduction materials and chemistry, PEC cells towards standalone devices that use photohybrid electrodes or solar cells have also been a hot topic in recent research. An overview of the state-of-the-art progress in PEC carbon dioxide reduction is presented and a deep understanding of the catalysts of carbon dioxide reduction is also given. PMID- 29193764 TI - The interstitium conducts extrarenal storage of sodium and represents a third compartment essential for extracellular volume and blood pressure homeostasis. AB - The role of salt in the pathogenesis of arterial hypertension is not well understood. According to the current understanding, the central mechanism for blood pressure (BP) regulation relies on classical studies linking BP and Na+ balance, placing the kidney at the very centre of long-term BP regulation. To maintain BP homeostasis, the effective circulating fluid volume and thereby body Na+ content has to be maintained within very narrow limits. From recent work in humans and rats, the notion has emerged that Na+ could be stored somewhere in the body without commensurate water retention to buffer free extracellular Na+ and that previously unidentified extrarenal, tissue-specific regulatory mechanisms are operative regulating the release and storage of Na+ from a kidney-independent reservoir. Moreover, immune cells from the mononuclear phagocyte system not only function as local on-site sensors of interstitial electrolyte concentration, but also, together with lymphatics, act as systemic regulators of body fluid volume and BP. These studies have established new and unexpected targets in studies of BP control and thus the pathophysiology of hypertension: the interstitium/extracellular matrix of the skin, its inherent interstitial fluid and the lymphatic vasculature forming a vessel network in the interstitium. Aspects of the interstitium in relation to Na+ balance and hypertension are the focus of this review. Taken together, observations of salt storage in the skin to buffer free extracellular Na+ and macrophage modulation of the extracellular matrix and lymphatics suggest that electrolyte homeostasis in the body cannot be achieved by renal excretion alone, but also relies on extrarenal regulatory mechanisms. PMID- 29193763 TI - Identification of a novel RPGRIP1 mutation in an Iranian family with leber congenital amaurosis by exome sequencing. AB - Leber congenital amaurosis (LCA) is a heterogeneous, early-onset inherited retinal dystrophy, which is associated with severe visual impairment. We aimed to determine the disease-causing variants in Iranian LCA and evaluate the clinical implications. Clinically, a possible LCA disease was found through diagnostic imaging, such as fundus photography, autofluorescence and optical coherence tomography. All affected patients showed typical eye symptoms associated with LCA including narrow arterioles, blindness, pigmentary changes and nystagmus. Target exome sequencing was performed to analyse the proband DNA. A homozygous novel c. 2889delT (p.P963 fs) mutation in the RPGRIP1 gene was identified, which was likely the deleterious and pathogenic mutation in the proband. Structurally, this mutation lost a retinitis pigmentosa GTPase regulator (RPGR)-interacting domain at the C-terminus which most likely impaired stability in the RPGRIP1 with the distribution of polarised proteins in the cilium connecting process. Sanger sequencing showed complete co-segregation in this pedigree. This study provides compelling evidence that the c. 2889delT (p.P963 fs) mutation in the RPGRIP1 gene works as a pathogenic mutation that contributes to the progression of LCA. PMID- 29193766 TI - Negative HBcAg in immunohistochemistry assay of liver biopsy is a predictive factor for the treatment of patients with nucleos(t)ide analogue therapy. AB - The hepatitis B core antigen (HBcAg) is an important target for antiviral response in chronic hepatitis B (CHB) patients. However, the correlation between HBcAg in the hepatocyte nucleus and nucleos(t)ide analogue (NA) therapeutic response is unclear. We sought to evaluate the role of HBcAg by analysing liver biopsies for viral response in NA-naive hepatitis B e antigen (HBeAg) positive (+) CHB patients via immunohistochemistry (IHC). A total of 48 HBcAg-negative (-) patients and 48 HBcAg (+) patients with matching baseline characteristics were retrospectively analysed for up to 288 weeks. Virological response (VR) rates of patients in the HBcAg (-) group were significantly higher at week 48 and 96 than the HBcAg (+) group (77.1% versus 45.8% at week 48, respectively, P = 0.002 and 95.3% versus 83.3% at week 96, respectively, P = 0.045). The serological negative conversion rate of HBeAg was significantly higher in the HBcAg (-) than in the HBcAg (+) group from week 96 to 288 (35.4 % versus 14.6% at week 96, respectively, P = 0.018; 60.4% versus 14.6%, respectively, P < 0.001 at week 144; 72.9% versus 35.4%, respectively, P < 0.001 at week 288). The cumulative frequencies of VR and lack of HBeAg were higher in the HBcAg (-) group (both P < 0.05). Binary logistic regression analysis showed that HBcAg (-) was the predictor for the lack of HBeAg (OR 4.482, 95% CI: 1.58-12.68). In summary, the absence of HBcAg in the hepatocyte nucleus could be an independent predictor for HBeAg seroconversion rates during NA-naive treatment in HBeAg (+) CHB patients. PMID- 29193765 TI - Group for Research and Assessment of Psoriasis and Psoriatic Arthritis/Outcome Measures in Rheumatology Consensus-Based Recommendations and Research Agenda for Use of Composite Measures and Treatment Targets in Psoriatic Arthritis. AB - OBJECTIVE: A meeting was convened by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) and Outcome Measures in Rheumatology (OMERACT) to further the development of consensus among physicians and patients regarding composite disease activity measures and targets in psoriatic arthritis (PsA). METHODS: Prior to the meeting, physicians and patients completed surveys on outcome measures. A consensus meeting of 26 rheumatologists, dermatologists, and patient research partners reviewed evidence on composite measures and potential treatment targets plus results of the surveys. The meeting consisted of plenary presentations, breakout sessions, and group discussions. International experts including members of GRAPPA and OMERACT were invited to the meeting, including the developers of all of the measures discussed. After discussions, participants voted on proposals for use, and consensus was established in a second survey. RESULTS: Survey results from 128 health care professionals and 139 patients were analyzed alongside a systematic literature review summarizing evidence. A weighted vote was cast for composite measures. For randomized controlled trials, the most popular measures were the PsA disease activity score (40 votes) and the GRAPPA composite index (28 votes). For clinical practice, the most popular measures were an average of scores on 3 visual analog scales (45 votes) and the disease activity in PsA score (26 votes). After discussion, there was no consensus on a composite measure. The group agreed that several composite measures could be used and that future studies should allow further validation and comparison. The group unanimously agreed that remission should be the ideal target, with minimal disease activity (MDA)/low disease activity as a feasible alternative. The target should include assessment of musculoskeletal disease, skin disease, and health-related quality of life. The group recommended a treatment target of very low disease activity (VLDA) or MDA. CONCLUSION: Consensus was not reached on a continuous measure of disease activity. In the interim, the group recommended several composites. Consensus was reached on a treatment target of VLDA/MDA. An extensive research agenda was composed and recommends that data on all PsA clinical domains be collected in ongoing studies. PMID- 29193767 TI - Empagliflozin decreases remnant-like particle cholesterol in type 2 diabetes patients with insulin resistance. AB - AIMS/INTRODUCTION: Remnant lipoproteins are thought to be atherogenic. Remnant like particle cholesterol (RLP-C), which reflects the levels of various kinds of remnant lipoproteins in the blood, has a significant correlation with insulin resistance. MATERIALS AND METHODS: In the present study, we measured the effect of empagliflozin (EMPA) on the levels of RLP-C, and investigated whether EMPA mediated change in RLP-C is associated with a change in insulin resistance in type 2 diabetes patients who have insulin resistance. RESULTS: Patients were allocated to receive a placebo (n = 51) or EMPA (n = 58) as an add-on treatment. Fasting blood samples were collected before and 12 weeks after this intervention. EMPA significantly decreased glycated hemoglobin, bodyweight, systolic blood pressure, plasma triglycerides, liver transaminases and estimated glomerular filtration rate, and increased high-density lipoprotein cholesterol. Furthermore, EMPA decreased RLP-C and homeostatic model assessment of insulin resistance. In the placebo group, there were no significant changes in these factors except for slight increases in liver transaminases. Multiple regression analysis showed that the change in homeostatic model assessment of insulin resistance (P = 0.0102) and the change in alanine aminotransferase (P = 0.0301) were significantly associated with the change in RLP-C in the EMPA group. The change in RLP-C significantly correlated with the change in homeostatic model assessment of insulin resistance (Pearson correlation coefficient 0.503, 95% confidence interval 0.199-0.719; P = 0.00241). CONCLUSION: EMPA decreases RLP-C levels, which is closely associated with amelioration of insulin sensitivity in diabetes patients who have insulin resistance.

AB - PURPOSE: Review the initial results of a single-center complete video-assisted thoracoscopic surgery (VATS) sleeve lobectomy and discuss the key procedure of this operation, in addition to its safety and feasibility. METHODS: Retrospectively analyze the perioperative data of 11 patients who accepted complete VATS sleeve lobectomy between May 2013 and Jun 2017 in Peking University Third Hospital, try to evaluate the safety of this procedure. All the patients were followed up and their oncological recurrence and metastasis were observed, and feasibility of VATS sleeve lobectomy for lung cancer was evaluated. RESULTS: All of the 11 cases underwent complete VATS sleeve lobectomy successfully and there is no conversion to thoracotomy. The mean operative time was 338 min (range from 243 to 511 min), the mean time of bronchial anastomotic was 63 min (range from 40 to 96 min), the mean blood loss was 205 mL (range from 50 to 400 mL), and the mean number of lymph nodes dissected is 22.1. There was no other complication except one patient suffered from high-risk pulmonary embolism, and no anastomotic leakage and stricture was found. The mean hospital stay postoperation was 8.7 days. The time of follow-up was between 2 and 38 months, only one out of the 11 cases died of bone metastasis, and the other 10 survived till now. One of these 10 patients had local recurrence 24 months after operation, and one suffered adenocarcinoma of esophageal-gastric junction at 15 months postoperation. The rest of eight patients all survived to June 2017 and no local recurrence and metastasis was found. The mean survival time was 14.8 months. CONCLUSION: Complete VATS sleeve lobectomy is a safe and feasible procedure, but the advantage of perioperative and long-term survival need prospective randomized controlled large sample trial to be confirmed. PMID- 29193769 TI - Inflammatory and Physiological Consequences of Debridement of Fibrous Tissue after Volumetric Muscle Loss Injury. AB - Volumetric muscle loss (VML) injuries present chronic loss of muscle fibers followed by expansive fibrotic tissue deposition. Regenerative medicine therapies are under development to promote regeneration. However, mitigation of the expansive fibrous tissue is required for integration with the remaining muscle. Using a porcine VML model, delayed debridement of injury fibrosis was performed 3 months post-VML and observed for an additional 4 weeks. A second group underwent the initial VML and was observed for 4 weeks, allowing comparison of initial fibrosis formation and debrided groups. The following salient observations were made: (i) debridement neither exacerbated nor ameliorated strength deficits; (ii) debridement results in recurrent fibrotic tissue deposition of a similar magnitude and composition as acute VML injury; and (iii) similarly upregulated transcriptional fibrotic and transcriptional pathways persist 4 weeks after initial VML or delayed debridement. This highlights the need for future studies to investigate adjunctive antifibrotic treatments for the fibrosed musculature. PMID- 29193770 TI - Development of a clinical prediction model for the postthrombotic syndrome in a prospective cohort of patients with proximal deep vein thrombosis. AB - : Essentials We developed a prediction model for postthrombotic syndrome (PTS) after deep vein thrombosis (DVT). High risk predictors were iliac vein DVT, BMI>35 and moderate-severe Villalta category. Patients with a score >=4 had an odds ratio of 5.9 (95% CI 2.1-16.6) for PTS. SOX-PTS score may select DVT patients for close monitoring or aggressive strategies to treat DVT. SUMMARY: Background Postthrombotic syndrome (PTS) is a chronic complication that develops in 20-50% of patients after deep vein thrombosis (DVT). Although individual risk factors for PTS have been characterized, the ability to predict which DVT patients are likely to develop PTS remains limited. Objective To develop a clinical prediction score for PTS in patients with DVT. Methods The derivation cohort consisted of participants in the SOX Trial, a randomized double-blind placebo-controlled trial of elastic compression stockings versus placebo stockings worn for 2 years after DVT to prevent PTS in patients with a first proximal DVT, enrolled in 24 community and tertiary-care hospitals from 2004 to 2010. Multivariable logistic regression analysis of baseline characteristics was performed. The outcome was the occurrence of PTS, diagnosed starting from 6 months or later according to Ginsberg's criteria. Results Seven hundred and sixty two patients were included in the analysis. The median follow-up was 728 days. The model includes three independent predictors, and has a range of possible scores from 0 to 5. High-risk predictors were: index DVT in the iliac vein; body mass index of >= 35 kg m-2 ; and moderate-severe Villalta severity category at DVT diagnosis. As compared with patients with a score of 0, those with a score of >= 4 had an odds ratio of 5.9 (95% confidence interval 2.1-16.6) for developing PTS. Conclusions To our knowledge, this is the first clinical prediction score for PTS. We identified three independent predictors that, when combined, predicted PTS risk after a first proximal DVT. The SOX-PTS score requires external validation before it can be considered for clinical use.

AB - Akabane virus (AKAV) is teratogenic to the foetus of domestic ruminants and causes a significant reproduction loss in cattle in Japan. In several past epizootics in cattle, AKAV was also associated with post-natal encephalomyelitis, mainly in calves and young stock. Previously analysed AKAV isolates in East Asia form two major clusters, genogroups I and II, with isolates involved in encephalomyelitis belonging mainly to the former. Between 2007 and 2013, AKAV epizootics were regularly observed in Japan during the summer/autumn season, and abnormal deliveries and post-natal encephalomyelitis caused by the virus in cattle were reported. During this period, 30 AKAV isolates were obtained from diseased and sentinel cattle, a piglet and Culicoides biting midges throughout Japan and were subjected to genetic comparison and phylogenetic analysis with previous isolates. In 2007, 2011 and 2013, AKAV belonging to genogroup I was identified in the central nervous systems of calves showing neurological disorders. Notably, a total of 165 cases of bovine encephalomyelitis were reported in 2011 and the isolated viruses from affected animals shared high genetic identities with a South Korean isolate that was associated with a large outbreak in 2010, suggesting some epidemiological linkage between these epizootics. Epizootics of genogroup II were observed in 2008 and 2010, but bovine post-natal encephalomyelitis cases rarely occurred. Our findings suggest that the frequent incursion of genogroup I isolates has increased the frequency of post natal encephalomyelitis cases in Japan in recent years. Infection by genogroup I virus was also identified in piglets with neurological disorders or congenital malformations in 2011 and 2013. The aetiological role of AKAV in pigs should be elucidated in the future. PMID- 29193772 TI - Efficacy of nivolumab in a patient with systemic refractory ALK+ anaplastic large cell lymphoma. PMID- 29193774 TI - Optical effects on the surrounding structure during quantitative analysis using indocyanine green videoangiography: A phantom vessel study. AB - Various reports have been published regarding quantitative evaluations of intraoperative fluorescent intensity studies using indocyanine green (ICG) with videoangiography (VAG). The effects of scattering and point-spread functions (PSF) on quantitative ICG-VAG evaluations have not been investigated. Clinically, when ICG is administered through the peripheral vein, it reaches the tissue intra arterially. To achieve more reliable intraoperative quantitative intensity evaluations, we examined the impact of high-intensity structures on close areas. The study was conducted using a phantom model and surgical fluorescent microscope. A region of interest (ROI) was created for the vessel model and another ROI was created within 3 cm of that. With an ROI of 6.8 mm in the vessel phantom model, 10% intensity was confirmed, even though there was no fluorescent structure. Intensity decreased gradually as the ROI moved further from the vessel model. Our study results suggest that the presence of a high-intensity structure and the size of the ROI may affect quantitative intensity evaluations using ICG VAG. Results of linear regression analysis indicate that the relationship of intensity (Y) and distance (X) is as follows: Y(real/A) = 29 Exp(-0.062X) + 164.3 Exp(-1.81X). The optical effect should be considered when performing an intraoperative intensity study with a surgical microscope.

AB - In this study, a green, rapid, and simple method, ionic-liquid-magnetized stirring bar liquid-phase microextraction was developed for the determination of naphthoquinones, including shikonin and beta,beta'-dimethylacrylshikonin, in Zicao. This method permits active magnetic stirring, extraction, and pre enrichment in a single device simultaneously, so the extract is conveniently collected. The analytes were extracted from the sample to ionic liquid-magnetized stirring bar, then the analyte-adsorbed magnetized stirring bar can be readily isolated from the sample solution by a magnet. The key experimental parameters were investigated and optimized, including the type and volume of ionic liquid, extraction time, salt concentration, stirring speed, and pH. The recoveries were in the range of 89.47-102.38%, and good reproducibilities were obtained with relative standard deviation below 5.36%. Compared with the conventional extraction methods, the proposed method is quicker and more effective. PMID- 29193776 TI - Bayesian statistical approaches to evaluating cognitive models. AB - Cognitive models aim to explain complex human behavior in terms of hypothesized mechanisms of the mind. These mechanisms can be formalized in terms of mathematical structures containing parameters that are theoretically meaningful. For example, in the case of perceptual decision making, model parameters might correspond to theoretical constructs like response bias, evidence quality, response caution, and the like. Formal cognitive models go beyond verbal models in that cognitive mechanisms are instantiated in terms of mathematics and they go beyond statistical models in that cognitive model parameters are psychologically interpretable. We explore three key elements used to formally evaluate cognitive models: parameter estimation, model prediction, and model selection. We compare and contrast traditional approaches with Bayesian statistical approaches to performing each of these three elements. Traditional approaches rely on an array of seemingly ad hoc techniques, whereas Bayesian statistical approaches rely on a single, principled, internally consistent system. We illustrate the Bayesian statistical approach to evaluating cognitive models using a running example of the Linear Ballistic Accumulator model of decision making (Brown SD, Heathcote A. The simplest complete model of choice response time: linear ballistic accumulation. Cogn Psychol 2008, 57:153-178).

PMID- 29193773 TI - Post-genomic behavioral genetics: From revolution to routine. AB - : What was once expensive and revolutionary-full-genome sequence-is now affordable and routine. Costs will continue to drop, opening up new frontiers in behavioral genetics. This shift in costs from the genome to the phenome is most notable in large clinical studies of behavior and associated diseases in cohorts that exceed hundreds of thousands of subjects. Examples include the Women's Health Initiative (www.whi.org), the Million Veterans Program (www. RESEARCH: va.gov/MVP), the 100 000 Genomes Project (genomicsengland.co.uk) and commercial efforts such as those by deCode (www.decode.com) and 23andme (www.23andme.com). The same transition is happening in experimental neuro- and behavioral genetics, and sample sizes of many hundreds of cases are becoming routine (www.genenetwork.org, www.mousephenotyping.org). There are two major consequences of this new affordability of massive omics datasets: (1) it is now far more practical to explore genetic modulation of behavioral differences and the key role of gene-by-environment interactions. Researchers are already doing the hard part-the quantitative analysis of behavior. Adding the omics component can provide powerful links to molecules, cells, circuits and even better treatment. (2) There is an acute need to highlight and train behavioral scientists in how best to exploit new omics approaches. This review addresses this second issue and highlights several new trends and opportunities that will be of interest to experts in animal and human behaviors. PMID- 29193777 TI - Pretreatment C-reactive protein/albumin ratio is associated with poor survival in patients with stage IB-IIA cervical cancer. AB - Previous studies have shown that the C-reactive protein/albumin ratio (CAR) is a prognostic indicator in multiple types of carcinomas. This study is the first to evaluate the prognostic significance of CAR in stage IB-IIA cervical cancer patients treated with radical surgery, as well as that of several other inflammation-based factors, including the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and prognostic nutritional index (PNI). A total of 235 patients were enrolled in this study. The optimal cut-off values of CAR and other inflammation-based factors were determined by receiver operating characteristic curves. The Kaplan-Meier method and Cox regression model analysis were performed to determine the independent predictors of progression-free survival (PFS) and overall survival (OS). At a cut-off value of 0.15, patients with a high CAR had significantly shorter PFS and OS than those with a lower CAR (P < 0.001). A higher CAR was significantly associated with elevated scores of NLR and PLR and a decreased PNI (P < 0.001). Univariate analyses showed that elevated CAR preoperatively was significantly associated with poor survival; a similar trend was also noted for the NLR, PLR, and PNI. Multivariate analyses demonstrated that only CAR was an independent indicator for PFS (hazard ratio [HR]: 5.164; 95% confidence interval [CI]: 2.495-10.687; P < 0.001) and OS (HR: 4.729; 95% CI: 2.263-9.882; P < 0.001). In conclusion, preoperative CAR is a novel and superior predictor of poor survival in patients with stage IB-IIA cervical cancer. PMID- 29193778 TI - A substitution mutation in OsPELOTA confers bacterial blight resistance by activating the salicylic acid pathway. AB - We previously reported a spotted-leaf mutant pelota (originally termed HM47) in rice displaying arrested growth and enhanced resistance to multiple races of Xanthomonas oryzae pv. oryzae. Here, we report the map-based cloning of the causal gene OsPELOTA (originally termed splHM47 ). We identified a single base substitution from T to A at position 556 in the coding sequence of OsPELOTA, effectively mutating phenylalanine to isoleucine at position 186 in the translated protein sequence. Both functional complementation and over-expression could rescue the spotted-leaf phenotype. OsPELOTA, a paralogue to eukaryotic release factor 1 (eRF1), shows high sequence similarity to Drosophila Pelota and also localizes to the endoplasmic reticulum and plasma membrane. OsPELOTA is constitutively expressed in roots, leaves, sheaths, stems, and panicles. Elevated levels of salicylic acid and decreased level of jasmonate were detected in the pelota mutant. RNA-seq analysis confirmed that genes responding to salicylic acid were upregulated in the mutant. Our results indicate that the rice PELOTA protein is involved in bacterial leaf blight resistance by activating the salicylic acid metabolic pathway. PMID- 29193779 TI - Insulin Access to Skeletal Muscle is Preserved in Obesity Induced by Polyunsaturated Diet. AB - OBJECTIVE: Diets high in saturated fat induce obesity and insulin resistance and impair insulin access to skeletal muscle, leading to reduced insulin levels at the muscle cell surface available to bind insulin receptors and induce glucose uptake. In contrast, diets supplemented with polyunsaturated fat improve insulin sensitivity (SI) and reduce the risk for type 2 diabetes. It was hypothesized that a diet high in polyunsaturated fat would preserve SI and insulin access to muscle, as compared with a diet high in saturated fat. METHODS: After 12 weeks of control, saturated (LARD), or polyunsaturated (salmon oil [SO]) high-fat diet feeding, muscle SI and insulin access to skeletal muscle were measured by using lymph, a surrogate of skeletal muscle interstitial fluid. RESULTS: Both high-fat diets induced similar weight gain, yet only LARD impaired SI. Hyperinsulinemia in the LARD group did not induce an increase in basal interstitial insulin, suggesting reduced insulin access to muscle after LARD, but not after SO. CONCLUSIONS: A diet high in polyunsaturated fat does not impair insulin access to muscle interstitium or induce insulin resistance as observed with a saturated fat diet, despite similar weight gain. Future studies should determine whether dietary SO supplementation improves impairments in insulin access to skeletal muscle. PMID- 29193780 TI - Presenting characteristics and prevalence of polypoidal choroidal vasculopathy in Scandinavian patients with treatment-naive exudative age-related macular degeneration. AB - PURPOSE: To study presenting characteristics and prevalence of polypoidal choroidal vasculopathy (PCV) in Scandinavian Caucasians with treatment-naive exudative age-related macular degeneration (AMD). METHODS: We reviewed all patients referred in year 2014 and diagnosed using fundus examination, optical coherence tomography, and fluorescein and indocyanine green angiography (ICGA). Details of found PCVs and its subtypes (clinical and angiographical) were correlated to the baseline best-corrected visual acuity (BCVA). RESULTS: Of 299 Caucasian patients with a tentative diagnosis of exudative AMD, 18 eyes of 17 patients (5.7%, CI 95%: 3.5-9.1%) had PCV. Patients with PCV were 75.8 (SD: 7.5) years old and 11 (65%) were females. Lesions were predominantly extramacular. Most eyes (56%) had subretinal haemorrhage, 39% had the exudative type and one (6%) eye had the quiescent type. Larger lesion area and disruption of the foveal inner-segment/outer-segment layer correlated with worse baseline BCVA. Polypoidal choroidal vasculopathy (PCV) type 1 was present in 50% and PCV type 2 in the other 50%. Polypoidal choroidal vasculopathy (PCV) type 1 was associated with a worse baseline BCVA and greater lesion size. CONCLUSION: Polypoidal choroidal vasculopathy (PCV) is not a rare condition in Danes with exudative AMD and presents often extramacular and with haemorrhage. This study underscores the importance of ICGA as a part of the diagnostic repertoire in AMD and suggests its routine use in Scandinavian populations. PMID- 29193781 TI - Impact of tumour motion compensation and delineation methods on FDG PET-based dose painting plan quality for NSCLC radiation therapy. AB - INTRODUCTION: To quantitatively estimate the impact of different methods for both boost volume delineation and respiratory motion compensation of [18F] FDG PET/CT images on the fidelity of planned non-uniform 'dose painting' plans to the prescribed boost dose distribution. METHODS: Six locally advanced non-small cell lung cancer (NSCLC) patients were retrospectively reviewed. To assess the impact of respiratory motion, time-averaged (3D AVG), respiratory phase-gated (4D GATED) and motion-encompassing (4D MIP) PET images were used. The boost volumes were defined using manual contour (MANUAL), fixed threshold (FIXED) and gradient search algorithm (GRADIENT). The dose painting prescription of 60 Gy base dose to the planning target volume and an integral dose of 14 Gy (total 74 Gy) was discretized into seven treatment planning substructures and linearly redistributed according to the relative SUV at every voxel in the boost volume. Fifty-four dose painting plan combinations were generated and conformity was evaluated using quality index VQ0.95-1.05, which represents the sum of planned dose voxels within 5% deviation from the prescribed dose. Trends in plan quality and magnitude of achievable dose escalation were recorded. RESULTS: Different segmentation techniques produced statistically significant variations in maximum planned dose (P < 0.02), as well as plan quality between segmentation methods for 4D GATED and 4D MIP PET images (P < 0.05). No statistically significant differences in plan quality and maximum dose were observed between motion compensated PET-based plans (P > 0.75). Low variability in plan quality was observed for FIXED threshold plans, while MANUAL and GRADIENT plans achieved higher dose with lower plan quality indices. CONCLUSIONS: The dose painting plans were more sensitive to segmentation of boost volumes than PET motion compensation in this study sample. Careful consideration of boost target delineation and motion compensation strategies should guide the design of NSCLC dose painting trials. PMID- 29193782 TI - Clinical and ex vivo laboratory comparison of the self-sealing properties and dimensional stability between the femtosecond laser and manual clear corneal incisions. AB - PURPOSE: To compare the self-sealing features and dimensional stability between the femtosecond laser (FL) and manual knife corneal incision. METHODS: For the clinical study, 29 consecutive eyes from 29 patients and 28 eyes from 28 patients who underwent cataract surgery with FL corneal incision and manual knife incision, respectively, were enrolled. Immediately after cataract surgery, the self-sealing features of the corneal incisions were evaluated. Scanning electron microscopy (SEM) images were obtained. For the experimental study, clear corneal incisions with a knife or FL with different energy settings (3, 6 and 9 MUJ) were created in fresh porcine eyes, followed by a stress test. The incision width was measured before and after the stress test. RESULTS: In the clinical study, the knife group had a higher self-sealing score (0.60 +/- 0.49 points) than the FL group (0.17 +/- 0.38 points). In the experimental study, the deformation rate in the knife incision (5.04 +/- 1.93) was significantly lower than that in the FL with any energy. The deformation rate in the 9 MUJ (12.98 +/- 2.76) was significantly higher than in the 3 MUJ (8.54 +/- 2.38) and 6 MUJ (8.82 +/- 2.85) FL energies. Scanning electron microscopy (SEM) images revealed that the corneal stromal surface of the knife incision was smoother than that of the FL. Higher energy FL showed more irregular surfaces. CONCLUSION: Higher FL energy tended to widen a clear corneal incision when mechanical stress was applied. The histological differences at the inner tunnel surface may cause differences in wound stability of the corneal incision. PMID- 29193783 TI - Blue Native/SDS-PAGE and iTRAQ-Based Chloroplasts Proteomics Analysis of Nicotiana tabacum Leaves Infected with M Strain of Cucumber Mosaic Virus Reveals Several Proteins Involved in Chlorosis Symptoms. AB - Virus infection in plants involves necrosis, chlorosis, and mosaic. The M strain of cucumber mosaic virus (M-CMV) has six distinct symptoms: vein clearing, mosaic, chlorosis, partial green recovery, complete green recovery, and secondary mosaic. Chlorosis indicates the loss of chlorophyll which is highly abundant in plant leaves and plays essential roles in photosynthesis. Blue native/SDS-PAGE combined with mass spectrum was performed to detect the location of virus, and proteomic analysis of chloroplast isolated from virus-infected plants was performed to quantify the changes of individual proteins in order to gain a global view of the total chloroplast protein dynamics during the virus infection. Among the 438 proteins quantified, 33 showed a more than twofold change in abundance, of which 22 are involved in the light-dependent reactions and five in the Calvin cycle. The dynamic change of these proteins indicates that light dependent reactions are down-accumulated, and the Calvin cycle was up-accumulated during virus infection. In addition to the proteins involved in photosynthesis, tubulin was up-accumulated in virus-infected plant, which might contribute to the autophagic process during plant infection. In conclusion, this extensive proteomic investigation on intact chloroplasts of virus-infected tobacco leaves provided some important novel information on chlorosis mechanisms induced by virus infection. PMID- 29193785 TI - Contribution of hiatal hernia to asthma in patients with gastroesophageal reflux disease. AB - BACKGROUND: To determine the correlation between asthma and hiatal hernia (HH) in patients with gastroesophageal reflux disease (GERD)-related asthma requiring laparoscopic anti-reflux surgery. METHODS: One hundred and thirty-six GERD patients with medically refractory asthma with (80 patients) or without HH (56 patients) were enrolled. Gastroesophageal reflux disease was assessed by endoscopy, esophageal manometry, reflux monitoring and symptom questionnaires, and treated with laparoscopic Nissen fundoplication (LNF) or LNF with concomitant hiatal hernia repair (LNF-HHR). The outcome measures included patients' satisfaction and drug independence. RESULTS: The patients with HH had lower esophageal sphincters (P = .005) and higher DeMeester scores (P = .014) than those without HH. After an average follow-up of 24 months, symptom scores were significantly decreased from the preoperative values (P < .05). Compared to LNF, LNF-HHR showed a better improvement in both esophageal and asthmatic symptoms (P < .0001 and P = .016, respectively). CONCLUSIONS: The patients with GERD with asthma have a high prevalence of HH. The presence of HH maybe correlated with asthma and severe GERD. Actively treating HH not only improved reflux, but also controlled asthma symptoms. PMID- 29193784 TI - Expression of CPPED1 in human trophoblasts is associated with timing of term birth. AB - Understanding of timing of human parturition is incomplete. Therefore, we carried out proteomic analyses of full-term placentas from uncomplicated pregnancies to identify protein signatures associated with the onset of spontaneous delivery. We found quantitative associations of 10 proteins with spontaneous term birth, evident either in the basal or in the chorionic plates or in both. Additional 18 proteins were associated according to the location within placenta indicating local variations in protein amounts. Calcineurin-like phosphoesterase domain containing 1 (CPPED1), a phosphatase previously suggested dephosphorylating AKT1/PKB, was one of the identified proteins. qRT-PCR revealed the mRNA level of CPPED1 was higher in elective caesarean deliveries than in spontaneous births, while immunohistochemistry showed CPPED1 in cytotrophoblasts, syncytiotrophoblasts and extravillous trophoblasts. Noteworthy, phosphorylation status of AKT1 did not differ between placentas from elective caesarean and spontaneous deliveries. Additionally, analyses of samples from infants indicated that single-nucleotide polymorphisms rs11643593 and rs8048866 of CPPED1 were associated with duration of term pregnancy. Finally, post-transcriptional silencing of CPPED1 in cultured HTR8/SVneo cells by siRNAs affected gene expression in pathways associated with inflammation and blood vessel development. We postulate that functions regulated by CPPED1 in trophoblasts at choriodecidual interphase have a role in the induction of term labour, but it may be independent of AKT1.

AB - BACKGROUND: Skin hyperpigmentation is the darkening of skin due to the increased production of melanin in the body. OBJECTIVES: To evaluate the efficacy and safety of a botanical-based Rosa E pigmentation serum in healthy fair skin female volunteers with wrinkles, skin tone, and pigmentation. METHODS: This was a single arm, open label study conducted in healthy Indian females; 18 subjects aged 30 55, having fair Caucasian-like skin with at least 2 dark skin pigments with facial wrinkles diagnosed by dermatologist were selected. Rosa E pigmentation serum was applied twice a day for 84 days. Effect was evaluated by (i) instrumental technique (spectrophotometer(r) 2600D), (ii) clinically by dermatologist regarding product efficacy (skin tone, antiwrinkle, pigmentation), and (iii) volunteers self-evaluation. RESULTS: The L* value of spectrophotometer reading represents lightness in the skin pigment. Reduction in the pigment was reported from day 14, with significant reductions observed till day 84 compared with baseline. Significant (P < .0001) skin pigmentation lightening was seen on day 14 (1.11) vastly improving on day 84 (1.94) based on photographic assessments. The significant reduction in skin pigment was 76.85%, Felix von Luschan skin color score was 30.24% (P < .0001) with a 7.38-fold reduction in skin tone and 57% reduction in facial wrinkles at day 84 from baseline. CONCLUSIONS: Rosa E pigmentation serum was found safe and effective in significant reduction in skin pigments, improvement of skin tone, and antiwrinkle properties instrumentally, clinically, and self-evaluation by volunteers. In these evaluations, best results were seen the longer the Rosa E was used. PMID- 29193789 TI - Temporal changes in retinal vascular parameters associated with successful panretinal photocoagulation in proliferative diabetic retinopathy: A prospective clinical interventional study. AB - PURPOSE: We aimed to investigate changes in retinal vascular geometry over time after panretinal photocoagulation (PRP) in patients with proliferative diabetic retinopathy (PDR). METHODS: Thirty-seven eyes with PDR were included. Wide-field fluorescein angiography (Optomap, Optos PLC., Dunfermline, Scotland, UK) was used to diagnose PDR at baseline and to assess activity at follow-up month three and six. At each time-point, a trained grader measured retinal vessel geometry on optic disc (OD) centred images using semiautomated software (SIVA, Singapore I Vessel Assessment, National University of Singapore, Singapore) according to a standardized protocol. RESULTS: At baseline, the mean age and duration of diabetes were 52.8 and 22.3 years, and 65% were male. Mean HbA1c was 69.9 mmol/mol, and blood pressure was 155/84 mmHg. Of the 37 eyes with PDR, eight (22%) eyes had progression at month three and 13 (35%) progressed over six months. Baseline characteristics, including age, sex, duration of diabetes, HbA1c, blood pressure, vessel geometric variables and total amount of laser energy delivered did not differ by progression status. However, compared to patients with progression of PDR, patients with favourable treatment outcome had alterations in the retinal arteriolar structures from baseline to month six (calibre, 154.3 MUm versus 159.5 MUm, p = 0.04, tortuosity 1.12 versus 1.10, p = 0.04) and in venular structures from baseline to month three (fractal dimension 1.490 versus 1.499, p = 0.04, branching coefficient (BC) 1.32 versus 1.37, p = 0.01). CONCLUSION: In patients with PDR, successful PRP leads to alterations in the retinal vascular structure. However, baseline retinal vascular geometry characteristics did not predict treatment outcome.

PMID- 29193792 TI - RPL18aB helps maintain suspensor identity during early embryogenesis. AB - During embryogenesis, plants are thought to use a mechanism that allows the suspensor to maintain its identity. Here, we reported that RPL18aB is involved in this mechanism in Arabidopsis thaliana. The suspensor cells proliferated in rpl18aB and formed a multicellular structure rather than undergo programmed cell death, as in wild type. Suspensors of rpl18aB expressed the embryo proper marker, DRN::GFP, but not the suspensor marker, WOX8::GFP. In addition, auxin accumulated throughout the suspensors of rpl18aB proembryos. Suspensor-specific expression of RPL18aB could rescue the cell proliferation defects in rpl18aB suspensors. These findings supported a role for RPL18aB in maintaining suspensor identity. PMID- 29193791 TI - IL-35 recombinant protein reverses inflammatory bowel disease and psoriasis through regulation of inflammatory cytokines and immune cells. AB - Interleukin-35 (IL-35), a member of the IL-12 family, functions as a new anti inflammatory factor involved in arthritis, psoriasis, inflammatory bowel disease (IBD) and other immune diseases. Although IL-35 can significantly prevent the development of inflammation in many diseases, there have been no early studies accounting for the role of IL-35 recombinant protein in IBD and psoriasis. In this study, we assessed the therapeutic potential of IL-35 recombinant protein in three well-known mouse models: the dextransulfate sodium (DSS)-induced colitis mouse model, the keratin14 (K14)-vascular endothelial growth factor A (VEGF-A) transgenic (Tg) psoriasis mouse model and the imiquimod (IMQ)-induced psoriasis mouse model. Our results indicated that IL-35 recombinant protein can slow down the pathologic process in DSS-induced acute colitis mouse model by decreasing the infiltrations of macrophages, CD4+ T and CD8+ T cells and by promoting the infiltration of Treg cells. Further analysis demonstrated that IL-35 recombinant protein may regulate inflammation through promoting the secretion of IL-10 and inhibiting the expression of pro-inflammatory cytokines such as IL-6, TNF-alpha and IL-17 in acute colitis model. In addition, lower dose of IL-35 recombinant protein could achieve long-term treatment effects as TNF-alpha monoclonal antibody did in the psoriasis mouse. In summary, the remarkable therapeutic effects of IL-35 recombinant protein in acute colitis and psoriasis mouse models indicated that IL-35 recombinant protein had a variety of anti-inflammatory effects and was expected to become an effective candidate drug for the treatment of inflammatory diseases.

PMID- 29193794 TI - Making stillbirths visible: a systematic review of globally reported causes of stillbirth. AB - BACKGROUND: Stillbirth is a global health problem. The World Health Organization (WHO) application of the International Classification of Diseases for perinatal mortality (ICD-PM) aims to improve data on stillbirth to enable prevention. OBJECTIVES: To identify globally reported causes of stillbirth, classification systems, and alignment with the ICD-PM. SEARCH STRATEGY: We searched CINAHL, EMBASE, Medline, Global Health, and Pubmed from 2009 to 2016. SELECTION CRITERIA: Reports of stillbirth causes in unselective cohorts. DATA COLLECTION AND ANALYSIS: Pooled estimates of causes were derived for country representative reports. Systems and causes were assessed for alignment with the ICD-PM. Data are presented by income setting (low, middle, and high income countries; LIC, MIC, HIC). MAIN RESULTS: Eighty-five reports from 50 countries (489 089 stillbirths) were included. The most frequent categories were Unexplained, Antepartum haemorrhage, and Other (all settings); Infection and Hypoxic peripartum (LIC), and Placental (MIC, HIC). Overall report quality was low. Only one classification system fully aligned with ICD-PM. All stillbirth causes mapped to ICD-PM. In a subset from HIC, mapping obscured major causes. CONCLUSIONS: There is a paucity of quality information on causes of stillbirth globally. Improving investigation of stillbirths and standardisation of audit and classification is urgently needed and should be achievable in all well-resourced settings. Implementation of the WHO Perinatal Mortality Audit and Review guide is needed, particularly across high burden settings. FUNDING: HR, SH, SHL, and AW were supported by an NHMRC-CRE grant (APP1116640). VF was funded by an NHMRC-CDF (APP1123611). TWEETABLE ABSTRACT: Urgent need to improve data on causes of stillbirths across all settings to meet global targets. PLAIN LANGUAGE SUMMARY: Background and methods Nearly three million babies are stillborn every year. These deaths have deep and long-lasting effects on parents, healthcare providers, and the society. One of the major challenges to preventing stillbirths is the lack of information about why they happen. In this study, we collected reports on the causes of stillbirth from high-, middle-, and low-income countries to: (1) Understand the causes of stillbirth, and (2) Understand how to improve reporting of stillbirths. Findings We found 85 reports from 50 different countries. The information available from the reports was inconsistent and often of poor quality, so it was hard to get a clear picture about what are the causes of stillbirth across the world. Many different definitions of stillbirth were used. There was also wide variation in what investigations of the mother and baby were undertaken to identify the cause of stillbirth. Stillbirths in all income settings (low-, middle-, and high-income countries) were most frequently reported as Unexplained, Other, and Haemorrhage (bleeding). Unexplained and Other are not helpful in understanding why a baby was stillborn. In low-income countries, stillbirths were often attributed to Infection and Complications during labour and birth. In middle- and high-income countries, stillbirths were often reported as Placental complications. Limitations We may have missed some reports as searches were carried out in English only. The available reports were of poor quality. Implications Many countries, particularly those where the majority of stillbirths occur, do not report any information about these deaths. Where there are reports, the quality is often poor. It is important to improve the investigation and reporting of stillbirth using a standardised system so that policy makers and healthcare workers can develop effective stillbirth prevention programs. All stillbirths should be investigated and reported in line with the World Health Organization standards.

AB - INTRODUCTION: Visualization of fiducial gold markers is critical for registration on computed tomography (CT) and magnetic resonance imaging (MRI) for imaging guided radiotherapy. Although larger markers provide better visualization on MRI, they tend to generate artifacts on CT. MRI is strongly influenced by the presence of metals, such as iron, in the body. Here we compared efficacies of a 0.5% iron containing gold marker (GM) and a traditional non-iron-containing marker. METHODS: Twenty-seven patients underwent CT/MRI fusion-based intensity-modulated radiotherapy. Markers were placed by urologists under local anesthesia. Gold Anchor (GA; diameter: 0.28 mm; length: 10 mm), an iron-containing marker, was placed on the right side of the prostate using a 22-G needle and VISICOIL (VIS; diameter: 0.35 mm; length: 10 mm), a non-iron-containing marker, was placed on the left side using a 19-G needle. T2*-weighted images MRI sequences were obtained. Two radiation oncologists and a radiation technologist evaluated and assigned scores for visual quality on a five-point scale (1, poor; 5, best visibility). RESULTS: Artifact generation on CT was slightly greater with GA than with VIS. The mean marker visualization scores on MRI of all three observers were significantly superior for GA than for VIS (3.5 vs 3.2, 3.9 vs 3.2, and 4.0 vs 2.9). The actual size of the spherical GA was about 2 mm in diameter, but the signal void on MRI was approximately 5 mm. CONCLUSION: Although both markers were well visualized and can be recommended clinically, the results suggest that GA has some subtle advantages for quantitative visualization that could prove useful in certain situations of stereotactic body radiotherapy and intensity-modulated radiotherapy. PMID- 29193795 TI - Lower mean blood glucose during short-term intensive insulin therapy is associated with long-term glycemic remission in patients with newly diagnosed type 2 diabetes: Evidence-based recommendations for standardization. AB - AIMS/INTRODUCTION: Optimal glycemic targets during short-term intensive insulin therapy in patients with newly diagnosed type 2 diabetes are not standardized. The present study was carried out to determine the optimal glycemic targets during therapy by analyzing the impacts of glucose levels on therapeutic outcomes. MATERIALS AND METHODS: A total of 95 individuals with newly diagnosed type 2 diabetes were enrolled. Short-term intensive insulin therapy was carried out using an insulin pump to achieve and maintain glycemic targets (fasting blood glucose <=6.0 mmol/L, 2-h postprandial blood glucose <=7.8 mmol/L) for 14 days, with daily eight-point capillary blood glucose profiles recorded. Patients were followed up for 1 year after discharge. RESULTS: In most participants, the mean blood glucose and glycemic excursion parameters during the therapy were controlled within the normal range. Mean blood glucose was independently associated with amelioration of acute insulin response (r = -0.25, P = 0.015) and 1-year remission (odds ratio 0.12, 95% confidence interval 0.034-0.426), but negatively associated with more level 1 hypoglycemia (r = -0.34, P = 0.001), although major hypoglycemia was rare. Among mean blood glucose tertiles, patients in the middle (68.7%) and lower (75.0%) tertiles had a higher 1-year remission rate compared with the upper tertile (32.3%, both P < 0.001), whereas only the middle tertile did not have increased hypoglycemia compared with the upper tertile (8.1 +/- 5.4 vs 7.2 +/- 3.9 events/person, P = 0.48). CONCLUSIONS: Stricter glycemic control during short-term intensive insulin therapy produced more remission despite self-manageable hypoglycemia. Based on glycemic parameters in the middle mean tertile, we propose new glycemic targets that are approximately 0.4 mmol/L lower than current the targets, as long-term benefit outweighs short-term risks.

PMID- 29193797 TI - The long non-coding RNA PVT1 represses ANGPTL4 transcription through binding with EZH2 in trophoblast cell. AB - Despite progress in diagnostics and treatment for preeclampsia, it remains the foremost cause of maternal and foetal perinatal morbidity and mortality worldwide. Over recent years, various lines of evidence have emphasized long non coding RNAs (lncRNAs) which function as an innovative regulator of biological behaviour, as exemplified by proliferation, apoptosis and metastasis. However, the role of lncRNAs has not been well described in preeclampsia. Here, we identified a lncRNA, PVT1, whose expression was down-regulated in qRT-PCR analyses in severe preeclampsia. The effects of PVT1 on development were studied after suppression and overexpression of PVT1 in HTR-8/SVneo and JEG3 cells. PVT1 knockdown notably inhibited cell proliferation and stimulated cell cycle accumulation and apoptosis. Exogenous PVT1 significantly increased cell proliferation. Based on analysis of RNAseq data, we found that PVT1 could affect the expression of numerous genes, and then investigated the function and regulatory mechanism of PVT1 in trophoblast cells. Further mechanistic analyses implied that the action of PVT1 is moderately attributable to its repression of ANGPTL4 via association with the epigenetic repressor Ezh2. Altogether, our study suggests that PVT1 could play an essential role in preeclampsia progression and probably acts as a latent therapeutic marker; thus, it might be a useful prognostic marker when evaluating new therapies for patients with preeclampsia. PMID- 29193799 TI - Preliminary Evaluation of Artemisinin-Cholesterol Conjugates as Potential Drugs for the Treatment of Intractable Forms of Malaria and Tuberculosis. AB - To evaluate the feasibility of developing drugs that may be active against both malaria and tuberculosis (TB) by using in part putative cholesterol transporters in the causative pathogens and through enhancement of passive diffusion in granulomatous TB, artemisinin-cholesterol conjugates were synthesized by connecting the component molecules through various linkers. The compounds were screened in vitro against Plasmodium falciparum (Pf) and Mycobacterium tuberculosis (Mtb). Antimalarial activities (IC50 ) against Pf drug-sensitive NF54, and drug-resistant K1 and W2 strains ranged from 0.03-2.6, 0.03-1.9, and 0.02-1.7 MUm. Although the compounds are less active than the precursor artemisinin derivatives, the cholesterol moiety renders the compounds relatively insoluble in the culture medium, and variation in solubilities among the different compounds may reflect in the range of efficacies observed. Activities against Mtb H37Rv were assessed using a standardized colony-forming unit (CFU) assay after 24 h pretreatment of cultures with each of the compounds. Percentage inhibition ranged from 3-38 % and 18-52 % at 10 and 80 MUm, respectively. Thus, in contrast to the comparator drug artemether, the conjugates display enhanced activities. The immediate aims include the preparation of conjugates with enhanced aqueous solubilities, assays against malaria and TB in vivo, and for TB, assays using an infected macrophage model and assessment of granuloma influx. PMID- 29193800 TI - Suppression of circadian secretion of glucagon-like peptide-1 by the saturated fatty acid, palmitate. AB - AIM: Glucagon-like peptide-1 is an incretin hormone secreted by the intestinal L cell with a circadian rhythm that parallels expression of the core clock gene, Bmal1. Although feeding rats a high-fat/high-sucrose Western diet impairs rhythmic glucagon-like peptide-1 release, the mechanisms underlying this effect remain unclear. Therefore, the aim of this study was to determine the pathway(s) by which the saturated fat, palmitate, a major component of the Western diet, impairs circadian glucagon-like peptide-1 secretion. METHODS: Murine mGLUTag L cells were synchronized, and the effects of palmitate pre-treatment on gene expression and glucagon-like peptide-1 secretion were determined, in addition to metabolite quantification, mitochondrial function analysis and enzyme inhibition and activation assays. Glucagon-like peptide-1 secretion was also analysed in ileal crypt cultures from control and Bmal1 knockout mice. RESULTS: Pre-treatment with palmitate dampened Bmal1 mRNA and protein expression and glucagon-like peptide-1 secretion at 8 but not 20 hours after cell synchronization (P < .05 .001). Glucagon-like peptide-1 release was also impaired in Bmal1 knockout cultures as compared to wild-type controls (P < .001). Palmitate pre-treatment reduced expression of the Bmal1 downstream target, nicotinamide phosphoribosyltransferase, the rate-limiting enzyme in the synthesis of NAD+ . This was paralleled by dampening of total NAD+ levels, as well as impaired mitochondrial function and ATP production (P < .05-.001). Whereas direct inhibition of nicotinamide phosphoribosyltransferase also decreased glucagon-like peptide-1 release, activation of this enzyme restored glucagon-like peptide-1 secretion in the presence of palmitate. CONCLUSION: Palmitate impairs L-cell clock function at the peak of Bmal1 gene expression, thereby impairing mitochondrial function and ultimately rhythmic glucagon-like peptide-1 secretion. PMID- 29193801 TI - A design-by-treatment interaction model for network meta-analysis and meta regression with integrated nested Laplace approximations. AB - Network meta-analysis (NMA) is gaining popularity for comparing multiple treatments in a single analysis. Generalized linear mixed models provide a unifying framework for NMA, allow us to analyze datasets with dichotomous, continuous or count endpoints, and take into account multiarm trials, potential heterogeneity between trials and network inconsistency. To perform inference within such NMA models, the use of Bayesian methods is often advocated. The standard inference tool is Markov chain Monte Carlo (MCMC), which is computationally expensive and requires convergence diagnostics. A deterministic approach to do fully Bayesian inference for latent Gaussian models can be achieved by integrated nested Laplace approximations (INLA), which is a fast and accurate alternative to MCMC. We show how NMA models fit in the class of latent Gaussian models and how NMA models are implemented using INLA and demonstrate that the estimates obtained by INLA are in close agreement with the ones obtained by MCMC. Specifically, we emphasize the design-by-treatment interaction model with random inconsistency parameters (also known as the Jackson model). Also, we have proposed a network meta-regression model, which is constructed by incorporating trial-level covariates to the Jackson model to explain possible sources of heterogeneity and/or inconsistency in the network. A publicly available R package, nmaINLA, is developed to automate the INLA implementation of NMA models, which are considered in this paper. Three applications illustrate the use of INLA for a NMA. PMID- 29193802 TI - A Synthetic MUC1 Anticancer Vaccine Containing Mannose Ligands for Targeting Macrophages and Dendritic Cells. AB - A MUC1 anticancer vaccine equipped with covalently linked divalent mannose ligands was found to improve the antigen uptake and presentation by targeting mannose-receptor-positive macrophages and dendritic cells. It induced much stronger specific IgG immune responses in mice than the non-mannosylated reference vaccine. Mannose coupling also led to increased numbers of macrophages, dendritic cells, and CD4+ T cells in the local lymph organs. Comparison of di- and tetravalent mannose ligands revealed an increased binding of the tetravalent version, suggesting that higher valency improves binding to the mannose receptor. The mannose-coupled vaccine and the non-mannosylated reference vaccine induced IgG antibodies that exhibited similar binding to human breast tumor cells. PMID- 29193803 TI - Investigating the robustness and extraction performance of a matrix-compatible solid-phase microextraction coating in human urine and its application to assess 2-6-ring polycyclic aromatic hydrocarbons using GC-MS/MS. AB - In this work, a polydimethylsiloxane/divinylbenzene fiber overcoated with a layer of polydimethylsiloxane was evaluated as analytical sampling tool for the first time in human urine. Urinary polycyclic aromatic hydrocarbons with 2-6 aromatic rings were considered as target compounds. The analyte uptake in kinetic and thermodynamic regime was evaluated and compared to the performances of polydimethylsiloxane/divinylbenzene and polydimethylsiloxane fibers. The assessment of the robustness and endurance of the overcoated fiber was carried out by direct immersion solid-phase microextraction in undiluted urine performing up to 120 consecutive extractions. The overcoated fiber was then used to develop a fast and easy direct immersion solid-phase microextraction with gas chromatography and triple quadrupole mass spectrometry protocol for the quantification of the target polycyclic aromatic hydrocarbons. The attained values of accuracy and precision were 75-114% and 2-19%, respectively, while the limits of quantification ranged between 0.05 and 1 ng/L. The proposed protocol was applied to the screening of urine samples collected from smoking and nonsmoking volunteers. The successful results obtained by using the overcoated fiber create not only new alternatives for polycyclic aromatic hydrocarbon exposure assessment but also new perspectives for the application of direct immersion solid-phase microextraction to the analysis of bioclinical matrixes. PMID- 29193804 TI - Primary cutaneous aspergillosis, mimicking malignancy, a rare presentation in an immunocompetent patient. AB - Aspergillus species are ubiquitous opportunistic molds that cause both allergic and invasive syndromes. A 65-year-old female, farmer by occupation, presented with left upper limb and trunk swelling for one year, associated with pain, tightening of skin, and vesicles with watery discharge. Local examination showed a diffuse swelling extending from left arm to forearm and lateral chest wall associated with edema, induration, and raised temperature. The swelling was firm to hard with superficial skin ulcers and black eschar. Hematological investigations of the patient showed raised total WBC count and peripheral blood eosinophilia. Patient had no history suggesting immunosuppression. Clinico radiological impression was left breast carcinoma with secondary skin involvement. fine-needle aspiration cytology (FNAC) from the swelling showed inflammatory cells, necrosis, epitheloid cell granulomas, and giant cells along with branching hyphae of variable thickness, confirmed on Gomori Methenamine Silver stain as fungal hyphae. Culture was advised which identified the species as Aspergillius fumigatus. Primary cutaneous infection by A. fumigatus in an immunocompetent patient is unheard of. FNAC has an important role in resolving diagnostic dilemma in primary cutaneous aspergillosis, which may mimic malignancy as in our case. PMID- 29193805 TI - Separation and determination of polyurethane amine catalysts in polyether polyols by using UHPLC-Q-TOF-MS on a reversed-phase/cation-exchange mixed-mode column. AB - A simple, selective, and accurate ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry method was established and validated for the efficient separation and quantification of polyurethane amine catalysts in polyether polyols. Amine catalysts were primarily separated in polyether polyol-based sample by solid-phase extraction, and further baseline separated on a reversed-phase/cation-exchange mixed-mode column (SiELC PrimesepTM 200) using 0.1% trifluoroacetic acid/acetonitrile as a mobile phase in gradient elution mode at a flow rate of 0.2 mL/min. High-resolution quadrupole time-of flight mass spectrometry analysis in electrospray ionization positive mode allowed the identification as N,N'-bis[3-(dimethylamino)propyl]urea, N-[2-(2 dimethylaminoethoxy)ethyl]-N-methyl-1,3-propanediamine, and N,N,N',N' tetramethyldipropylenetriamine. The method was validated and presented good linearity for all the analytes in blank matrices within the concentration range of 0.20-5.0 or 0.1-2.0 MUg/mL with the correlation coefficients (R2 ) ranging from 0.986 to 0.997. Method recovery ranged within 81-105% at all three levels (80, 100, and 120% of the original amount) with relative standard deviations of 1.0-6.2%. The limits of detection were in the range of 0.007-0.051 MUg/mL. Good precision was obtained with relative standard deviation below 3.2 and 0.72% for peak area and retention time of three amines, respectively. PMID- 29193806 TI - Inhibition of larval growth and adult fecundity in Asian long-horned beetle (Anoplophora glabripennis) exposed to azadirachtins under quarantine laboratory conditions. AB - BACKGROUND: The Asian long-horned beetle [ALB; Anoplophora glabripennis (Motschulsky)] is an invasive, wood-boring insect posing significant economic and ecological threats to the deciduous forests of North America. An efficacious and environmentally acceptable chemical control technique is a requirement of a comprehensive, integrated response strategy. RESULTS: Results of this study demonstrate statistically significant, concentration-dependent effects of azadirachtins, a family of natural compounds derived from the neem tree, on both ALB larval and adult life stages. Growth inhibitory effects on ALB larvae were greatest on early life stages. Significant effects on adults included inhibition of female feeding, oviposition effort and fecundity for adults exposed to azadirachtins via maturation feeding on systemically loaded twigs. CONCLUSION: These quarantine laboratory experiments verify multi-mechanistic, deleterious effects on both larval and adult life stages of ALB, an exotic, invasive insect pest of critical importance in North America. Field efficacy studies are required to further understand dose acquisition by larval and adult ALB life stages following systemic injections to host trees under semi-operational use scenarios. Such studies could also be used to test postulates regarding optimal deployment strategies to meet objectives such as slowing the spread of this pest and protection of high-value deciduous forest resources.

PMID- 29193807 TI - Thermal plasticity potentially mediates the interaction between host Chilo partellus Swinhoe (Lepidoptera: Crambidae) and endoparasitoid Cotesia flavipes Cameron (Hymenoptera: Braconidae) in rapidly changing environments. AB - BACKGROUND: Increasing climatic average temperatures and variability elicit various insect physiological responses that affect fitness and survival and may influence subsequent trophic interactions in agroecosystems. In this background, we investigated short- and long-term plastic responses to temperature of the laboratory-reared stemborer Chilo partellus and its larval endoparasitoid Cotesia flavipes. RESULTS: Rapid cold- and heat-hardening effects in C. partellus larvae, pupae and adults and C. flavipes adults were highly significant (P < 0.001). High temperature acclimation improved critical thermal limits and heat knockdown time in C. partellus larvae and C. flavipes adults, respectively. Low-temperature acclimation enhanced the supercooling point in C. flavipes and the chill coma recovery time in both C. partellus larvae and C. flavipes adults. CONCLUSION: The results of this study suggest that thermal plasticity may enhance the survival of these two species when they are subjected to lethal low and high temperatures. However, C. partellus appeared to be more plastic than C. flavipes. These results have three major implications: (1) C. partellus may inhabit slightly warmer environments than C. flavipes, suggesting a potential mismatch in biogeography; (2) host-parasitoid relationships are complex and are probably trait dependent, and (3) host-parasitoid differential thermal plastic responses may offset biocontrol efficacy. These results may help inform biocontrol decision making under conditions of global change. (c) 2017 Society of Chemical Industry. PMID- 29193808 TI - Molecular epidemiological characterization of Brucella isolates from sheep and yaks in northwest China. AB - Animal brucellosis is a re-emerging disease in China with high prevalence in the northwest region. A total of 66 isolates of Brucella were recovered from sheep and yaks in the Inner Mongolia, Xinjiang, Qinghai and Gansu provinces of northwest China in 2015 and 2016. Using classical biotyping and the Brucella AMOS PCR assay, all isolates were identified as Brucella melitensis biovar 3 (n = 58), B. melitensis biovar 1 (n = 1), Brucella abortus (n = 5), or Brucella suis biovar 3 (n = 2), and B. melitensis biovar 3 was found to be mainly responsible for sheep brucellosis in northwest China. Multilocus variable-number tandem-repeat analysis (MLVA) was used to identify the epidemiological relationships among the isolates and to assess their genetic diversity. Multilocus variable-number tandem repeat analysis-16 identified 46 genotypes in these populations, including 37 unique and nine shared genotypes. Multilocus variable-number tandem-repeat analysis-11 showed that 71% of the isolates (47 of 66) were genotype 116 (1-5-3 13-2-2-3-2-4-41-8), a characteristic subgroup of the East Mediterranean group, showing that isolates from different geographical areas exhibit similar epidemiological characteristics in different regions and may be epidemiologically linked. Multilocus variable-number tandem-repeat analysis-11 also revealed that an isolate from Inner Mongolia had a novel genotype, 369 (1-5-3-13-2-2-3-2-7-41 8). Multilocus variable-number tandem-repeat analysis-16 genotyping of northwest China Brucella isolates allows a better understanding of the epidemiology of animal brucellosis in this region. This study is the first analysis of B. melitensis in Gansu province, and the results confirmed that in this province, isolates of this species are disorderly and unsystematic. PMID- 29193809 TI - Enhanced headspace single drop microextraction method using deep eutectic solvent based magnetic bucky gels: Application to the determination of volatile aromatic hydrocarbons in water and urine samples. AB - A facile headspace single drop microextraction method was developed using deep eutectic solvent-based magnetic bucky gel as the extraction solvent for the first time. The hydrophobic magnetic bucky gel was formed by combining choline chloride/chlorophenol deep eutectic solvent and magnetic multiwalled carbon nanotube nanocomposite. Magnetic susceptibility, high viscosity, high sorbing ability, and tunable extractability of organic analytes are the desirable advantages of the prepared gel. Using a rod magnet as a suspensor in combination with the magnetic susceptibility of the prepared gel resulted in a highly stable droplet. This stable droplet eliminated the possibility of drop dislodgement. The prepared droplet made it possible to complete the extraction process in high temperatures and elevated agitation rates. Furthermore, using larger micro droplet volumes without any operational problems became possible. These facts resulted in shorter sample preparation time, higher sensitivity of the method, and lower detection limits. Under the optimized conditions, an enrichment factor of 520-587, limit of detection of 0.05-0.90 ng/mL, and linearity range of 0.2 2000 ng/mL (coefficient of determination = 0.9982-0.9995) were obtained. Relative standard deviations were < 10%. This method was successfully coupled with gas chromatography and used for the determination of benzene, toluene, ethylbenzene, and xylene isomers as harmful volatile organic compounds in water and urine samples.

AB - PURPOSE: To highlight the variations in published definitions of hypotony and their impact on reported clinical outcomes. To propose a revised definition, focusing on clinically significant hypotony (CH). METHODS: Literature review of hypotony definitions published between January 2010 and December 2015 was carried out. Numerical definitions for hypotony, its onset, duration and associated clinical signs were recorded. Each definition was applied to surgical outcomes data collected prospectively from a cohort of 300 glaucoma patients treated at a single centre. The sensitivity and specificity of each definition in identifying CH [defined as low intraocular pressure (IOP) with signs of maculopathy hypotony and choroidal detachment] were calculated. RESULTS: A total of 128 eligible papers were identified, and 14 different definitions for hypotony were extracted. In 53 (41.4%), hypotony was not defined. In the remaining 75 (58.6%), the numerical definitions varied between 4 and 8 mmHg, and of these, 24 (32%) included the onset and duration of hypotony as part of the definition. Definition dependent hypotony rates within the cohort varied between 1% and 59.3%. No statistical differences were found between the groups based on corneal thickness or axial length. Clinically significant hypotony (CH) was identified in 37 (12.3%), with large differences in the sensitivity and specificity among published definition. CONCLUSION: Variations in defining postoperative hypotony can have a large impact on the reported success and failure rates among studies. There is a need for a more robust universal definition, focusing on clinically important signs, to allow better comparison between different treatment modalities.

AB - We report a case of a 72 year old male with hyperparathyroidism secondary to end stage diabetic renal disease and coexisting bilateral chromophobe renal cell carcinomas. The patient presented with back and groin pain, right pelvic hemorrhage, and multiple lytic bone lesions concerning for metastatic renal cell carcinoma. Fine needle aspiration cytology demonstrated benign appearing osteoclasts and spindled cells. A concurrent core biopsy showed foci of spindled cell proliferation populated by osteoclast-like giant cells with stromal hemorrhage without evidence of metastatic carcinoma. The cytologic and histologic findings, in correlation with the clinical history, radiographic features, markedly increased parathyroid hormone levels and other serologic studies, were diagnostic of the reactive lesion seen in brown tumor of hyperparathyroidism secondary to chronic renal failure. PMID- 29193814 TI - Hospital admissions for lower respiratory tract infections in children born moderately/late preterm. AB - OBJECTIVE: To evaluate the frequency and predictors of hospital admissions for lower respiratory tract infections (LRTIs) in moderately preterm (MP, 32+0 to 33+6 weeks) and late preterm (LP, 34+0 to 36+6 weeks) infants compared to term (T >=37 weeks) and very preterm (VP, <32+0 weeks) infants. STUDY DESIGN: This national register-based study covered all infants born in Finland in 1991-2008. Data on 1 018 256 infants were analyzed in four gestational age-based groups: VP (n = 6329), MP (n = 6796), LP (n = 39 928), and T (n = 965 203) groups. Data on hospital admissions due to bronchiolitis/bronchitis and pneumonia were collected up to the age of 7 years. RESULTS: Hospital admissions for LRTIs were more common in the MP and LP groups than in the T group but less frequent than in the VP group: bronchiolitis/bronchitis (VP 24.4%, MP 13.9%, LP 9.5%, and T 5.6%) and pneumonia (VP 8.8%, MP 4.5%, LP 3.3%, and T 2.4%). Compared to the term group, MP and LP birth predicted bronchiolitis/bronchitis (MP OR 1.89; 95%CI 1.75-2.03, LP 1.51; 1.45-1.56) and pneumonia (MP 1.49; 1.32-1.67, LP 1.25; 1.18-1.33) admissions. Statistically significant risk factors for LRTIs included maternal smoking, cesarean section, male sex, admission to a neonatal unit and ventilator therapy. In addition, being first-born, being born SGA and neonatal antibiotic therapy were associated with bronchiolitis/bronchitis. CONCLUSIONS: MP and LP births, in addition to VP birth, have a significant impact on respiratory infectious morbidity and the need of hospital admissions for LRTIs.

AB - C-Phycocyanin is the major phycobiliprotein in Arthrospira platensis, also known as Spirulina, which is a cyanobacterium used as a dietary supplement because of its powerful effects on body and brain. C-phycocyanin is a blue-colored accessory photosynthetic pigment with multiple applications in food industry as natural dye or additive, and in pharmaceuticals. This study presents a simple protocol for the extraction and purification of food-grade C-phycocyanin from Arthrospira platensis. The cell lysis of cyanobacterium was performed by sonication combined with repeated freezing and thawing cycles. The purification of the crude extract of C-phycocyanin was carried out by ammonium sulfate precipitation followed by ion exchange chromatography resulting in 2.5 purity. The purity of phycocyanobilin chromophore has been tested by UV-visible spectrophotometry by monitoring the absorption after each stage of purification. A high-performance liquid chromatography method has been developed and validated for the determination of food-grade C-phycocyanin. Intra- and interday precision values less than 5.6% and recovery greater than 91.2% indicated high precision and accuracy of the method for analysis of C-phycocyanin. The method has been applied to commercial confectionery of blue color and to the purified protein obtained in the first stage of the study. PMID- 29193816 TI - Genetic Fine-Mapping and Identification of Candidate Genes and Variants for Adiposity Traits in Outbred Rats. AB - OBJECTIVE: Obesity is a major risk factor for multiple diseases and is in part heritable, yet the majority of causative genetic variants that drive excessive adiposity remain unknown. Here, outbred heterogeneous stock (HS) rats were used in controlled environmental conditions to fine-map novel genetic modifiers of adiposity. METHODS: Body weight and visceral fat pad weights were measured in male HS rats that were also genotyped genome-wide. Quantitative trait loci (QTL) were identified by genome-wide association of imputed single-nucleotide polymorphism (SNP) genotypes using a linear mixed effect model that accounts for unequal relatedness between the HS rats. Candidate genes were assessed by protein modeling and mediation analysis of expression for coding and noncoding variants, respectively. RESULTS: HS rats exhibited large variation in adiposity traits, which were highly heritable and correlated with metabolic health. Fine-mapping of fat pad weight and body weight revealed three QTL and prioritized five candidate genes. Fat pad weight was associated with missense SNPs in Adcy3 and Prlhr and altered expression of Krtcap3 and Slc30a3, whereas Grid2 was identified as a candidate within the body weight locus. CONCLUSIONS: These data demonstrate the power of HS rats for identification of known and novel heritable mediators of obesity traits. PMID- 29193820 TI - Osteology and Radiological Anatomy of the Thoracic Limbs of Temminck's Ground Pangolin (Smutsia temminckii). AB - Temminck's ground pangolin is the only pangolin present in South Africa. It is a myrmecophagous mammal with a bipedal gait. The thoracic limbs are used to break open ant nests, dig for food, and expand previously occupied burrows. This study describes the osteology and radiological anatomy of the thoracic limbs of this threatened species. Thoracic limbs from four Temminck's ground pangolins, which succumbed from electrocution or natural causes, were digitally radiographed in situ. The individual bones were then cleaned, described and digitally radiographed. The skeleton of the thoracic limbs revealed a similar number and arrangement of bones compared to that of domestic carnivores. The bones were robust and displayed numerous open epiphyseal lines. The latter provide an estimate of sexual maturity and should not be confused with fractures in injured ground pangolins. The scapula was broad and triangular-shaped. The humerus displayed a massive medial epicondyle. The radius and ulna were similarly sized, and displayed a broad radial trochlea and large olecranon tuber, respectively. The manus was composed of seven carpal bones, five short metacarpal bones and five digits of which the three central digits were the best developed. The unguicular process of the distal phalanx was bifid and elongated. The osteological characteristics indicate that the thoracic limbs of Temminck's ground pangolin are specifically adapted for protraction and retraction, strong elbow extension, flexion of the carpus and digits as well as pronation and supination of the antebrachium, as opposed to weight-bearing. These functions are likewise documented for other scratch-digging species. Anat Rec, 301:624-635, 2018. (c) 2017 Wiley Periodicals, Inc. PMID- 29193819 TI - Efficacy and Safety of Selexipag in Adults With Raynaud's Phenomenon Secondary to Systemic Sclerosis: A Randomized, Placebo-Controlled, Phase II Study. AB - OBJECTIVE: To determine the effect of selexipag, an oral, selective IP prostacyclin receptor agonist, on the frequency of attacks of Raynaud's phenomenon (RP) in patients with systemic sclerosis (SSc). METHODS: Patients with SSc-related RP were randomized 1:1 to placebo (n = 38) or selexipag (n = 36) in individualized doses (maximum of 1,600 MUg twice daily) during a 3-week titration period. The primary end point was the weekly average number of RP attacks during the study maintenance period, analyzed using a Bayesian approach with a negative binomial model adjusted for baseline number of RP attacks. Other outcome measures included Raynaud's Condition Score (RCS), RP attack duration, and treatment emergent adverse events (AEs). RESULTS: Baseline characteristics were comparable between treatment groups. For 83.3% of patients, the individualized maintenance dosage of selexipag was <=800 MUg twice daily. No significant difference was observed between placebo and selexipag in weekly average number of electronic diary (eDiary)-recorded RP attacks during the maintenance period (14.2 attacks during the maintenance period and 21.5 attacks during the baseline week in the placebo group [n = 32] versus 18.0 attacks during the maintenance period and 22.4 attacks during the baseline week in the selexipag group [n = 27]; adjusted mean treatment difference of 3.4 in favor of placebo). No significant treatment effect was observed on RCS or RP attack duration. In the double-blind period, 86.8% of placebo-treated patients and 100% of selexipag-treated patients reported >=1 AE; 55.3% and 91.7%, respectively, reported >=1 prostacyclin-associated AE. CONCLUSION: Treatment with selexipag did not reduce the number of RP attacks compared with placebo. The safety profile of selexipag was similar to that previously reported. This study provides important information about the feasibility of eDiary reporting of RP attacks in clinical trials.

PMID- 29193822 TI - Evaluating refraction and visual acuity with the Nidek autorefractometer AR-360A in a randomized population-based screening study. AB - PURPOSE: The evaluation of visual acuity (VA) and refraction in the Northern Finland Birth Cohort Eye study was performed using the Nidek AR-360A autorefractometer. The accuracy of the method for this population-based screening study was assessed. METHODS: Measurements of the refractive error were obtained from the right eyes of 1238 subjects (mean age 47), first objectively with the AR 360A and then subjectively by an optometrist. Agreement with the subjective refraction was calculated for sphere, cylinder, mean spherical equivalent (MSE), cylindrical vectors J45 and J0 and presbyopic correction (add). Visual acuity (VA) was measured using an ETDRS chart and the autorefractometer. RESULTS: The refractive error measured with the AR-360A was higher than the subjective refraction performed by the optometrist for sphere (0.007 D +/- 0.24 D p = 0.30) and also for cylinder (-0.16 D +/- 0.20 D p < 0.0005). The bias between the measurements of MSE, J45 and J0 was low: -0.07 D +/- 0.22 D (p = 0.002), 0.01 D +/- 0.43 D (p = 0.25) and -0.01 D +/- 0.42 D (p = 0.43), respectively. The amount of add measured by the autorefractometer was higher than the subjective 0.35 D +/ 0.29 D (p < 0.0005). There was a statistically significant correlation between VA (p < 0.0005) and the difference between the subjective and objective refraction. In 99.2% of the measurements, visual values were within one decimal line of each other. CONCLUSION: The Nidek AR-360A autorefractometer is an accurate tool for determining the refraction and VA in a clinical screening trial.

AB - The location, number and size of the central and peripheral neurons innervating the ischiocavernous muscle (ICM) were studied in male pigs by means of Fast Blue (FB) retrograde neuronal tracing. Moreover the immunohistochemical properties of the sympathetic ganglia were investigated combining the double immunolabeling method. After injection of FB into the left ICM, a mean number of 245.3 +/- 134.9 labeled neurons were found in the ipsilateral ventral horn of the S1-S3 segments of the spinal cord (SC), 129.7 +/- 45.5 in the L6-S3 ipsilateral and S2-S3 contralateral spinal ganglia (SGs), 2279.3 +/- 622.1 in the ipsilateral L2-S2 and contralateral L5-S2 sympathetic trunk ganglia (STGs), 541.7 +/- 158 in the bilateral caudal mesenteric ganglia (CMGs), and 78.3 +/- 35.8 in the microganglia of the pelvic plexus (PGs). The mean area of the ICM projecting neurons was 1217 +/- 69.7 MUm2 in the SC, 2737.5 +/- 176.5 MUm2 in the SGs, 982.8 +/- 36.8 MUm2 in the STGs, 865.9 +/- 39.14 MUm2 in the CMGs and 426.2 +/- 24.72 MUm2 in the PGs. The FB positive neurons of autonomic ganglia contained Dopamine beta hydroxylase, vesicular acetylcholine transporter, neuronal nitric oxyde sinthase, calcitonine gene related peptide, leu-enkephaline, neuropeptide Y, substance P, vasoactive intestinal polypeptide, and somatostatine often colocalized with tyrosine hydroxylase. The particular localization of the motor somatic nucleus, the abundant autonomic innervation and the qualitatively different content of ICM projecting sympathetic neurons suggest a complex regulation of this striated muscle involved in involuntary functions, such as the erection, ejaculation, micturition and defecation.

AB - Membrane fouling commonly occurs in all filter types during virus filtration in protein-based biopharmaceutical manufacturing. Mechanisms of decline in virus filter performance due to membrane fouling were investigated using a cellulose based virus filter as a model membrane. Filter performance was critically dependent on solution conditions; specifically, ionic strength. To understand the interaction between immunoglobulin G (IgG) and cellulose, sensors coated with cellulose were fabricated for surface plasmon resonance and quartz crystal microbalance with energy dissipation measurements. The primary cause of flux decline appeared to be irreversible IgG adsorption on the surface of the virus filter membrane. In particular, post-adsorption conformational changes in the IgG molecules promoted further irreversible IgG adsorption, a finding that could not be adequately explained by DLVO theory. Analyses of adsorption and desorption and conformational changes in IgG molecules on cellulose surfaces mimicking cellulose based virus removal membranes provide an effective approach for identifying ways of optimizing solution conditions to maximize virus filter performance.

AB - Health-related quality of life (QOL) and depression burden of Mexican Americans with end-stage renal disease (ESRD) are not known. This observational cross sectional study assessed QOL and depression and examined their inter-relatedness in Mexican Americans with type 2 diabetes and ESRD on maintenance hemodialysis (HD) treatment. Prevalent Mexican Americans on HD (N = 40) completed the Kidney Disease Quality of Life-Short Form (KDQOL-SF) and the Beck Depression Inventory II. The overall median scores for the mental component summary and the physical component summary scales in the KDQOL-SF were 40.9 and 34.0, respectively. The prevalence of severe depression was 40%. The most significant differences between depressed and non-depressed groups were symptom/problem list, cognitive function, and emotional well- being (P < 0.0001 for all). Mexican Americans with depression endure a more dismal QOL compared to non-depressed peers. Significant negative correlations between depression and several QOL scales underscore plausible interactions between the two conditions which warrants further evaluation. PMID- 29193826 TI - Validation of eye-tracking measures of social attention as a potential biomarker for autism clinical trials. AB - : Social communication impairments are a core feature of autism spectrum disorder (ASD), and this class of symptoms is a target for treatments for the disorder. Measures of social attention, assessed via eye-gaze tracking (EGT), have been proposed as an early efficacy biomarker for clinical trials targeting social communication skills. EGT measures have been shown to differentiate children with ASD from typical children; however, there is less known about their relationships with social communication outcome measures that are typically used in ASD clinical trials. In the present study, an EGT task involving viewing a videotape of an actor making bids for a child's attention was evaluated in 25 children with ASD aged 24-72 months. Children's attention to the actor during the dyadic bid condition measured via EGT was found to be strongly associated with five well validated caregiver-reported outcome measures that are commonly used to assess social communication in clinical trials. These results highlight the convergent validity of EGT measures of social attention in relation to caregiver-reported clinical measures. EGT holds promise as a non-invasive, quantitative, and objective biomarker that is associated with social communication abilities in children with ASD. Autism Res 2018, 11: 166-174. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Eye-gaze tracking (EGT), an automated tool that tracks eye-gaze patterns, might help measure outcomes in clinical trials investigating interventions to treat autism spectrum disorders. In this study, an EGT task was evaluated in children with ASD, who watched a video with an actor talking directly to them. Patterns of eye-gaze were associated with caregiver-reported measures of social communication that are used in clinical trials. We show EGT may be a promising objective tool measuring outcomes.

AB - Biallelic likely pathogenic variants in SLC52A2 and SLC52A3 cause riboflavin transporter deficiency. It is characterized by muscle weakness, ataxia, progressive ponto-bulbar palsy, amyotrophy, and sensorineural hearing loss. Oral riboflavin halts disease progression and may reverse symptoms. We report two new patients whose clinical and biochemical features were mimicking mitochondrial myopathy. Patient 1 is an 8-year-old male with global developmental delay, axial and appendicular hypotonia, ataxia, and sensorineural hearing loss. His muscle biopsy showed complex II deficiency and ragged red fibers consistent with mitochondrial myopathy. Whole exome sequencing revealed a homozygous likely pathogenic variant in SLC52A2 (c.917G>A; p.Gly306Glu). Patient 2 is a 14-month old boy with global developmental delay, respiratory insufficiency requiring ventilator support within the first year of life. His muscle biopsy revealed combined complex II + III deficiency and ragged red fibers consistent with mitochondrial myopathy. Whole exome sequencing identified a homozygous likely pathogenic variant in SCL52A3 (c.1223G>A; p.Gly408Asp). We report two new patients with riboflavin transporter deficiency, caused by mutations in two different riboflavin transporter genes. Both patients presented with complex II deficiency. This treatable neurometabolic disorder can mimic mitochondrial myopathy. In patients with complex II deficiency, riboflavin transporter deficiency should be included in the differential diagnosis to allow early treatment and improve neurodevelopmental outcome. PMID- 29193831 TI - Mimicking corneal stroma using keratocyte-loaded photopolymerizable methacrylated gelatin hydrogels. AB - Cell-laden methacrylated gelatin (GelMA) hydrogels with high (approximately 90%) transparency were prepared to mimic the natural form and function of corneal stroma. They were synthesized from GelMA with a methacrylation degree of 70% as determined by nuclear magnetic resonance. Hydrogels were strong enough to withstand handling. Stability studies showed that 87% of the GelMA hydrogels remained after 21 days in phosphate buffered saline (PBS). Cell viability in the first 2 days was over 90% for the human keratocytes loaded in the gels as determined with the live-dead analysis. Cells in the hydrogel elongated and connected to each other as observed by confocal laser scanning microscopy (CLSM) images and scanning electron microscope analysis after 3 weeks in the culture medium and cells were seen to be distributed throughout the hydrogel bulk. Cells were found to synthesize collagen Types I and V, decorin, and biglycan (representative collagens and proteoglycans of human corneal stroma, respectively) showing that keratocytes maintained their functions and preserved their phenotypes in the hydrogels. Transparency of cell-loaded and cell-free hydrogels after 21 days was found to be over 90% at all time points in the visible light range and was comparable to the transparency of the native cornea. The corneal stroma equivalent produced in this study that has cells entrapped in it leads to a product with homogenous distribution of cells. It was transparent at the very beginning and is expected to allow better vision than nontransparent substrates. It, therefore, has a significant potential to be used as an alternative to the current products used to treat corneal blindness. PMID- 29193832 TI - Decision making for independent municipal action. AB - Municipalities and cities face myriad challenges with regard to planning; decisions that will have long-standing consequences need to be made in the context of pressing present concerns, constrained budgets, and uncertainty about the future under climate changes. Compounding the challenge may be a lack of clear signals from the state and federal leadership on investment priorities. This paper contends that existing strategies from decision science can prove useful for local governments as they seek actions that are robust despite uncertain futures and broadly beneficial across sectors and time horizons. An illustrative example of decision making with scenario analysis demonstrates how a city can prioritize funding and elevate the baseline functionality of its infrastructure and the well-being of its residents, regardless of when and how climate hazards occur.

PMID- 29193830 TI - Effects of cosmetics on the skin microbiome of facial cheeks with different hydration levels. AB - Basic cosmetics was used by volunteers belonging to high (HHG) and low (LHG) hydration groups for 4 weeks, and bacterial communities and biophysical parameters in facial skin were analyzed. Hydration level increases and transepidermal water loss and roughness decreases were observed in both groups after cosmetic use. Bacterial diversity was greater in LHG than HHG, and increased after cosmetic use in both groups. Bray-Curtis dissimilarities that were higher in LHG than HHG increased in HHG after cosmetic use, whereas they decreased in LHG. The phyla Actinobacteria, Proteobacteria, Firmicutes, and Bacteroidetes and the genera Propionibacterium, Ralstonia, Burkholderia, Staphylococcus, Corynebacterium, Cupriavidus, and Pelomonas were identified as common groups and they were not significantly different between LHG and HHG except for Propionibacterium that was more abundant in HHG. After cosmetic use, Propionibacterium, Staphylococcus, and Corynebacterium decreased, whereas Ralstonia, not a core genus, increased, as did KEGG categories of lipid metabolism and xenobiotics biodegradation and metabolism, suggesting that Ralstonia in skin may have the ability to metabolize cosmetics components. Bacterial communities after cosmetic use were different from those in both LHG and HHG before the cosmetic use, indicating that bacterial communities in LHG were not shifted to resemble those in HHG by cosmetics use. PMID- 29193833 TI - Diminished long-term recovery of peak flow rate (PFR) after robotic prostatectomy in men with baseline PFR <10 mL/s and incidental association with high-risk prostate cancer. AB - OBJECTIVE: The aim of this study was to evaluate the effects of robot-assisted radical prostatectomy (RARP) on uroflowmetry (UF) parameters among men with baseline peak flow rates (PFR) <10 mL/s. METHODS: A single-surgeon RARP database of 1082 men who underwent prospective UF testing was analyzed. Men filled out International Prostate Symptom Score questionnaires and underwent uroflowmetry and post-void bladder ultrasound before surgery and at each follow-up visit. Patients were divided into 2 groups based on preoperative PFR: those with PFR <10 mL/s (n = 158) and those with PFR >=10 mL/s (n = 924). Univariate and multivariate regression models tested the association of preoperative characteristics in predicting postoperative PFR improvement. Within the PFR <10 mL/s group, preoperative variables were analyzed to predict pathologic outcomes. RESULTS: Three months after RARP, men with baseline PFR <10 mL/s had a 3-fold improvement in PFR (from mean of 7.0 to 24.2 mL/s), whereas in men with PFR >=10 mL/s there was a 50% improvement (from mean of 19.7 to 28.9 mL/s; P < .001). Improvement in PFR remained stable for >5 years, but mean postoperative PFR was 20% lower in men with baseline PFR <10 mL/s. Preoperative prostate-specific antigen (odds ratio [OR] 0.75; 95% confidence interval [CI] 0.59-0.95) and PFR (OR 0.52; 95% CI 0.34-0.80) were independent predictors of the percentage improvement in men with baseline PFR <10 mL/s. Preoperative PFR <=7 mL/s was an independent predictor of Gleason score >=8 (P = .016), seminal vesicle invasion (P = .010), and lymph node invasion (0.029). CONCLUSIONS: After RARP, PFR improved significantly, with the improvement persisting over long-term follow-up. However, men with baseline PFR <10 mL/s had a 20% lower postoperative PFR over 5 years, suggesting permanent damage to the bladder and the need for early treatment to maintain bladder health. There appears to be an association between baseline PFR <=7 mL/s and adverse pathologic features. PMID- 29193834 TI - Supplementary search methods were more effective and offered better value than bibliographic database searching: A case study from public health and environmental enhancement. AB - BACKGROUND: We undertook a systematic review to evaluate the health benefits of environmental enhancement and conservation activities. We were concerned that a conventional process of study identification, focusing on exhaustive searches of bibliographic databases as the primary search method, would be ineffective, offering limited value. The focus of this study is comparing study identification methods. We compare (1) an approach led by searches of bibliographic databases with (2) an approach led by supplementary search methods. We retrospectively assessed the effectiveness and value of both approaches. METHODS: Effectiveness was determined by comparing (1) the total number of studies identified and screened and (2) the number of includable studies uniquely identified by each approach. Value was determined by comparing included study quality and by using qualitative sensitivity analysis to explore the contribution of studies to the synthesis. RESULTS: The bibliographic databases approach identified 21 409 studies to screen and 2 included qualitative studies were uniquely identified. Study quality was moderate, and contribution to the synthesis was minimal. The supplementary search approach identified 453 studies to screen and 9 included studies were uniquely identified. Four quantitative studies were poor quality but made a substantive contribution to the synthesis; 5 studies were qualitative: 3 studies were good quality, one was moderate quality, and 1 study was excluded from the synthesis due to poor quality. All 4 included qualitative studies made significant contributions to the synthesis. CONCLUSIONS: This case study found value in aligning primary methods of study identification to maximise location of relevant evidence. PMID- 29193835 TI - Incident Spine Surgery in Patients With Ankylosing Spondylitis: A Secondary Cohort Analysis of a Nationwide, Population-Based Health Claims Database. AB - OBJECTIVE: To evaluate the risk of the need for spine surgery, including cervical and lumbar spine surgeries in patients with ankylosing spondylitis (AS), compared with those without the disease. METHODS: A secondary data analysis was conducted using population-based claims data from the Taiwan National Health Insurance Research Database. Adult patients with newly diagnosed AS between January 2000 and December 2012 were identified based on the International Classification of Diseases, Ninth Revision, Clinical Modification code 720.0. A comparison cohort was assembled using frequency-matched sex, 10-year age intervals, and index year with the AS cohort at a ratio of 5:1. All patients were followed until our study outcomes (any spine surgery, cervical spine surgery, and lumbar spine surgery), based on surgical codes, had occurred, or until the end of the followup period. Incidence rate ratios (IRRs) were calculated using Poisson regression models. RESULTS: We identified 3,462 patients with AS and 17,310 patients without AS. All 3 outcome variables were seen at a significantly higher incidence in the AS cohort than in the comparison cohort (IRR 2.34 [95% confidence interval (95% CI) 1.92-2.87] for any spine surgery, IRR 2.36 [95% CI 1.55-3.59] for cervical spine surgery, and IRR 2.33 [95% CI 1.85-2.93] for lumbar spine surgery). Moreover, the magnitudes of the IRRs were the largest in the youngest age group (individuals in their 20s and 30s). CONCLUSION: Patients with AS, particularly those in their 20s and 30s, had a significantly higher risk of needing any spine surgery, cervical spine surgery, and lumbar spine surgery, compared with patients without AS.

AB - Nanomechanics has played a vital role in pushing our capability to detect, probe, and manipulate the biological species, such as proteins, cells, and tissues, paving way to a deeper knowledge and superior strategies for healthcare. Nanomechanical characterization techniques, such as atomic force microscopy, nanoindentation, nanotribology, optical tweezers, and other hybrid techniques have been utilized to understand the mechanics and kinetics of biospecies. Investigation of the mechanics of cells and tissues has provided critical information about mechanical characteristics of host body environments. This information has been utilized for developing biomimetic materials and structures for tissue engineering and artificial implants. This review summarizes nanomechanical characterization techniques and their potential applications in healthcare research. The principles and examples of label-free detection of cancers and myocardial infarction by nanomechanical cantilevers are discussed. The vital importance of nanomechanics in regenerative medicine is highlighted from the perspective of material selection and design for developing biocompatible scaffolds. This review interconnects the advancements made in fundamental materials science research and biomedical technology, and therefore provides scientific insight that is of common interest to the researchers working in different disciplines of healthcare science and technology. PMID- 29193839 TI - Implementing noninvasive follicular thyroid neoplasm with papillary-like nuclear features may potentially impact the risk of malignancy for thyroid nodules categorized as AUS/FLUS and FN/SFN. AB - BACKGROUND: Noninvasive encapsulated follicular variant of papillary thyroid carcinoma (PTC) has recently been reclassified as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). Implementation of the new terminology may alter the implied risk of malignancy (ROM) across the six categories of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). METHODS: The study cohort consisted of thyroid fine needle aspiration (FNA) cases which were assessed between January 2011 and June 2016 and led to surgical resections. For each case, patient demographics as well as cytologic and corresponding histologic diagnoses were recorded. The surgical specimens diagnosed as follicular variant of PTC (FVPTC) were re-reviewed to identify cases that met the diagnostic criteria for NIFTP. The ROM with and without exclusion of NIFTP from malignant categorization, as well as the relative change in ROM were calculated for individual categories of TBSRTC. RESULTS: A total of 908 FNA cases with surgical follow-up were retrieved and PTC was identified in 252 (27.8%) surgical specimens. Twenty-nine of 252 (11.5%) were initially classified as FVPTC, of which 17 (6.7%) were reclassified as NIFTP. The cytologic interpretations for the majority of NIFTP cases were atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS, n = 8) or follicular neoplasm/suspicious for neoplasm/(FN/SFN, n = 4). Excluding NIFTP from malignant categorization resulted in a relative decrease in ROM in AUS/FLUS (25.8%) and FN/SFN (22.3%) categories. CONCLUSION: Our institutional data demonstrates that eliminating NIFTP from malignant categorization may result in a reduction of the implied ROM for AUS/FLUS and FN/SFN categories. PMID- 29193837 TI - Weight Change During the Early Rheumatoid Arthritis Period and Risk of Subsequent Mortality in Women With Rheumatoid Arthritis and Matched Comparators. AB - OBJECTIVE: To investigate whether weight change during the early rheumatoid arthritis (RA) period is associated with subsequent mortality and to evaluate whether there is an RA-specific effect. METHODS: We identified patients with incident RA during the Nurses' Health Study (NHS; 1976-2016) and created a comparison cohort by matching each RA patient with up to 10 non-RA comparators by age and calendar year of the RA diagnosis (index date). To capture weight change around the early RA period ("peri-RA/index"), we used weight measurements collected 2-4 years before and 2-4 years after the index date. We used Cox regression analysis to estimate hazard ratios (HRs) for mortality according to peri-RA/index weight change categories, separately in each cohort and in the combined cohorts, evaluating for an RA-specific effect. RESULTS: Among 121,701 women in the NHS, 902 patients with incident RA were identified and matched to 7,884 non-RA comparators. In the RA cohort, 371 deaths (41.1%) occurred during a mean follow-up of 17.0 years after the early RA period, and 2,303 deaths (29.2%) occurred in the comparison cohort during a mean follow-up of 18.4 years. Weight loss of >30 pounds during the peri-RA period had a hazard ratio (HR) for mortality of 2.78 (95% confidence interval [95% CI] 1.58-4.89) compared to stable weight; results in the comparison cohort were similar (HR 2.16, 95% CI 1.61 2.88). A weight gain of >30 pounds had no association with mortality in patients with RA (HR 1.45, 95% CI 0.69-3.07) or comparators (HR 1.19, 95% CI 0.89-1.59). For mortality, there was no statistically significant interaction between RA/comparator status and weight change category (P = 0.68). CONCLUSION: Severe weight loss during the early RA period was associated with an increased subsequent mortality risk for women with and those without RA. These results extend prior observations by including non-RA comparators and finding no protective association between weight gain and mortality, providing evidence against an RA-specific obesity paradox for mortality. PMID- 29193840 TI - Overweight, Obesity, and the Likelihood of Achieving Sustained Remission in Early Rheumatoid Arthritis: Results From a Multicenter Prospective Cohort Study. AB - OBJECTIVE: Obesity is implicated in rheumatoid arthritis (RA) development, severity, outcomes, and treatment response. We estimated the independent effects of overweight and obesity on ability to achieve sustained remission (sREM) in the 3 years following RA diagnosis. METHODS: Data were from the Canadian Early Arthritis Cohort, a multicenter observational trial of early RA patients treated by rheumatologists using guideline-based care. sREM was defined as Disease Activity Score in 28 joints (DAS28) <2.6 for 2 consecutive visits. Patients were stratified by body mass index (BMI) as healthy (18.5-24.9 kg/m2 ), overweight (25 29.9 kg/m2 ), and obese (>=30 kg/m2 ). Cox regression was used to estimate the effect of the BMI category on the probability of achieving sREM over the first 3 years, controlling for age, sex, race, education, RA duration, smoking status, comorbidities, baseline DAS28, Health Assessment Questionnaire disability index, C-reactive protein level, and initial treatment. RESULTS: Of 982 patients, 315 (32%) had a healthy BMI, 343 (35%) were overweight, and 324 (33%) were obese; 355 (36%) achieved sREM within 3 years. Initial treatment did not differ by BMI category. Compared to healthy BMI, overweight patients (hazard ratio [HR] 0.75 [95% confidence interval (95% CI) 0.58-0.98]) and obese patients (HR 0.53 [95% CI 0.39-0.71]) were significantly less likely to achieve sREM. CONCLUSION: Rates of overweight and obesity were high (69%) in this early RA cohort. Overweight patients were 25% less likely, and obese patients were 47% less likely, to achieve sREM in the first 3 years, despite similar initial disease-modifying antirheumatic drug treatment and subsequent biologic use. This is the largest study demonstrating the negative impact of excess weight on RA disease activity and supports a call to action to better identify and address this risk in RA patients. PMID- 29193841 TI - Interfacial Engineering of Supported Liquid Membranes by Vapor Cross-Linking for Enhanced Separation of Carbon Dioxide. AB - Supported liquid membranes (SLMs) based on ionic liquids (ILs) with not only high gas permeability and selectivity, but also high stability under high pressure, are highly desired for gas separation applications. In this work, permeable and selective polyamide network (PN) layers are deposited on the surface of SLMs by utilizing the cross-linking reaction of trimesoyl chloride, which was pre dispersed in the SLMs, and vapor of amine linkers. The vapor cross-linking method makes it easy to control the growth and aggregation of PN layers, owing to the significantly reduced reaction rate, and thereby ensuring the good distribution of PN layers on the surface of SLMs. With rational choice of amine linkers and optimization of vapor cross-linking conditions, the prepared sandwich-like PN@SLMs with ILs embedded homogeneously within polymeric matrices displayed much improved CO2 permeability and CO2 /N2 selectivity in relation to the pristine SLMs. Moreover, those SLMs with ILs impregnated into porous supports physically displayed improved stability under high pressure after vapor cross-linking, because the PN layers formed on the surface of SLMs help prevent the ILs from being squeezed out. This interfacial engineering strategy represents a significant advance in the surface modification of SLMs to endow them with promising applications in CO2 capture. PMID- 29193842 TI - Determining the Risk Factors and Clinical Features Associated With Severe Gastrointestinal Dysmotility in Systemic Sclerosis. AB - OBJECTIVE: A subset of patients with systemic sclerosis (SSc) develop severe gastrointestinal (GI) dysmotility. We sought to determine predictors of severe SSc GI dysmotility and to identify distinct features associated with this phenotype. METHODS: Patients with SSc who required supplemental nutrition (enteral or parenteral tube feeding) were compared to SSc patients with mild GI symptoms in a cross-sectional analysis. The association between severe GI dysmotility and clinical and serologic features was examined using logistic regression. Baseline data were examined to determine predictors of developing severe GI dysfunction using Cox regression. RESULTS: SSc patients with severe GI dysmotility (n = 66) were more likely than those patients with mild GI symptoms (n = 1,736) to be male (odds ratio [OR] 2.47 [95% confidence interval (95% CI) 1.34-4.56]; P = 0.004), and to have myopathy (OR 5.53 [95% CI 2.82-10.82]; P < 0.001), and sicca symptoms (OR 2.40 [95% CI 1.30-4.42]; P = 0.005), even after adjustment for potential confounders. Baseline features that were associated with the future development of severe GI dysfunction included male sex (hazard ratio [HR] 2.99 [95% CI 1.53-5.84]; P = 0.001) and myopathy (HR 5.08 [95% CI 2.21 11.67]; P < 0.001). CONCLUSION: Distinct clinical features are present in SSc patients who are at risk of developing severe GI dysmotility. This finding is not only important clinically but also suggests that a unique pathologic process is at work in these patients. PMID- 29193843 TI - Polyoxometalate and Resin-Derived P-Doped Mo2 C@N-Doped Carbon as a Highly Efficient Hydrogen-Evolution Reaction Catalyst at All pH Values. AB - A new type of P-doped Mo2 C coated by N-doped carbon (P-Mo2 C@NC) has been successfully prepared by calcining a mixture of H3 [PMo12 O40 ] polyoxometalates (POMs) and urea-formaldehyde resin under an N2 atmosphere. Urea-formaldehyde resin not only serves as the carbon source to ensure carbonization but also facilitates the uniform distribution of POM precursors, which efficiently avoid the aggregation of Mo2 C particles at high temperatures. TEM analysis revealed that the average diameter of the Mo2 C particles was about 10 nm, which is coated by a few-layer N-doped carbon sheet. The as-prepared P-Mo2 C@NC displayed excellent hydrogen-evolution reaction (HER) performance and long-term stability in all pH environments. To reach a current density of 10 mA cm-2 , only 109, 159, and 83 mV were needed for P-Mo2 C@NC in 0.5 m H2 SO4 (pH 0), 0.1 m phosphate buffer (pH 7), and 1 m KOH (pH 14), respectively. This could provide a high-yield and low-cost method to prepare uniform nanosized molybdenum carbides with highly efficient and stable HER performance.

AB - The poor mechanical stability of chitosan has long impeded its industrial utilization as an immobilization carrier. In this study, the mechanical properties of chitosan beads were greatly improved through utilizing the slow rate of the sodium bicarbonate-induced chitosan gelation and combining it with the chemical cross-linking action of glutaraldehyde (GA). The GA-treated sodium bicarbonate-gelled chitosan beads exhibited much better mechanical properties and up to 2.45-fold higher observed activity of the immobilized enzyme (beta-D galactosidase (beta-gal)) when compared to the GA-treated sodium tripolyphosphate (TPP)-gelled chitosan beads. The differences between the sodium bicarbonate gelled and the TPP-gelled chitosan beads were proven visually and also via scanning electron microscopy, elemental analysis, and differential scanning calorimetry. Moreover, the optimum pH, the optimum temperature, the apparent Km , and the apparent Vmax of the beta-gals immobilized onto the two aforementioned types of chitosan beads were determined and compared. A reusability study was also performed. This study proved the superiority of the sodium bicarbonate gelled chitosan beads as they retained 72.22 +/- 4.57% of their initial observed activity during the 13th reusability cycle whereas the TPP-gelled beads lost their activity during the first four reusability cycles, owing to their fragmentation.

PMID- 29193845 TI - Anticancer Properties of Halogenated Pyrrolo[3,2-d]pyrimidines with Decreased Toxicity via N5 Substitution. AB - Halogenated pyrrolo[3,2-d]pyrimidine analogues have shown antiproliferative activity in recent studies, with cell accumulation occurring in the G2 /M stage without apoptosis. However, the mechanism of action and pharmacokinetic (PK) profile of these compounds has yet to be determined. To investigate the PK profile of these compounds, a series of halogenated pyrrolo[3,2-d]pyrimidine compounds was synthesized and first tested for activity in various cancer cell lines followed by a mouse model. EC50 values ranged from 0.014 to 14.5 MUm, and maximum tolerated doses (MTD) in mice were between 5 and 10 mg kg-1 . This indicates a wide variance in activity and toxicity that necessitates further study. To decrease toxicity, a second series of compounds was synthesized with N5 alkyl substitutions in an effort to slow the rate of metabolism, which was thought to be leading to the toxicity. The N-substituted compounds demonstrated comparable cell line activity (EC50 values between 0.83-7.3 MUm) with significantly decreased toxicity (MTD=40 mg kg-1 ). Finally, the PK profile of the active N5-substituted compound shows a plasma half-life of 32.7 minutes, and rapid conversion into the parent unsubstituted analogue. Together, these data indicate that halogenated pyrrolo[3,2-d]pyrimidines present a promising lead into potent antiproliferative agents with tunable activity and toxicity, and rapid metabolism. PMID- 29193846 TI - Microprinted Stem Cell Niches Reveal Compounding Effect of Colony Size on Stromal Cells-Mediated Neural Differentiation. AB - Microenvironmental factors have a major impact on differentiation of embryonic stem cells (ESCs). Here, a novel phenomenon that size of ESC colonies has a significant regulatory role on stromal cells induced differentiation of ESCs to neural cells is reported. Using a robotic cell microprinting technology, defined densities of ESCs are confined within aqueous nanodrops over a layer of supporting stromal cells immersed in a second, immiscible aqueous phase to generate ESC colonies of defined sizes. Temporal protein and gene expression studies demonstrate that larger ESC colonies generate disproportionally more neural cells and longer neurite processes. Unlike previous studies that attribute neural differentiation of ESCs solely to interactions with stromal cells, it is found that increased intercellular signaling of ESCs significantly enhances neural differentiation. This study offers an approach to generate neural cells with improved efficiency for potential use in translational research. PMID- 29193847 TI - Genetic loss of diazepam binding inhibitor in mice impairs social interest. AB - Neuropsychiatric disorders in which reduced social interest is a common symptom, such as autism, depression, and anxiety, are frequently associated with genetic mutations affecting gamma-aminobutyric acid (GABA)ergic transmission. Benzodiazepine treatment, acting via GABA type-A receptors, improves social interaction in male mouse models with autism-like features. The protein diazepam binding inhibitor (DBI) can act as an endogenous benzodiazepine, but a role for DBI in social behavior has not been described. Here, we investigated the role of DBI in the social interest and recognition behavior of mice. The responses of DBI wild-type and knockout male and female mice to ovariectomized female wild-type mice (a neutral social stimulus) were evaluated in a habituation/dishabituation task. Both male and female knockout mice exhibited reduced social interest, and DBI knockout mice lacked the sex difference in social interest levels observed in wild-type mice, in which males showed higher social interest levels than females. The ability to discriminate between familiar and novel stimulus mice (social recognition) was not impaired in DBI-deficient mice of either sex. DBI knockouts could learn a rotarod motor task, and could discriminate between social and nonsocial odors. Both sexes of DBI knockout mice showed increased repetitive grooming behavior, but not in a manner that would account for the decrease in social investigation time. Genetic loss of DBI did not alter seminal vesicle weight, indicating that the social interest phenotype of males lacking DBI is not due to reduced circulating testosterone. Together, these studies show a novel role of DBI in driving social interest and motivation. PMID- 29193848 TI - Mesoporous Silica and Organosilica Nanoparticles: Physical Chemistry, Biosafety, Delivery Strategies, and Biomedical Applications. AB - Predetermining the physico-chemical properties, biosafety, and stimuli responsiveness of nanomaterials in biological environments is essential for safe and effective biomedical applications. At the forefront of biomedical research, mesoporous silica nanoparticles and mesoporous organosilica nanoparticles are increasingly investigated to predict their biological outcome by materials design. In this review, it is first chronicled that how the nanomaterial design of pure silica, partially hybridized organosilica, and fully hybridized organosilica (periodic mesoporous organosilicas) governs not only the physico chemical properties but also the biosafety of the nanoparticles. The impact of the hybridization on the biocompatibility, protein corona, biodistribution, biodegradability, and clearance of the silica-based particles is described. Then, the influence of the surface engineering, the framework hybridization, as well as the morphology of the particles, on the ability to load and controllably deliver drugs under internal biological stimuli (e.g., pH, redox, enzymes) and external noninvasive stimuli (e.g., light, magnetic, ultrasound) are presented. To conclude, trends in the biomedical applications of silica and organosilica nanovectors are delineated, such as unconventional bioimaging techniques, large cargo delivery, combination therapy, gaseous molecule delivery, antimicrobial protection, and Alzheimer's disease therapy. PMID- 29193849 TI - Apparent transverse relaxation (R2*) on MRI as a method to differentiate treatment effect (pseudoprogression) versus progressive disease in chemoradiation for malignant glioma. AB - INTRODUCTION: Pseudoprogression (psPD) is a transient post-treatment imaging change that is commonly seen when treating glioma with chemotherapy and radiation. The use of apparent transverse relaxation rate (R2*), which is calculated from a contrast-free multi-echo gradient echo Magnetic Resonance Imaging (MRI) sequence, may allow for quantitative identification of patients with suspected psPD. METHODS: We acquired a multi-echo gradient echo sequence using a 3T-Siemens Prisma MRI. The signal decay through the echoes was fitted to provide the R2* coefficient. We segmented the T1 -gadolinium enhancing the image to provide a contrast enhancing lesion (CEL) and the FLAIR hyperintensity to provide a non-enhancing lesion (NEL). These regions of interest were applied to the multi-echo gradient echo to acquire a mean R2* within the CEL and NEL. We additionally acquired ADC data to attempt to corroborate our findings. RESULTS: We found that patients who later exhibited PD exhibited a higher R2* within the CEL as well as a higher ratio of CEL to NEL. Our data correctly distinguished pseudoprogression from treatment effect in 9/9 patients, while ADC corrected identified 7/9 patients using an absolute ADC of 1200 * 10-6 mm2 /s. CONCLUSIONS: Our method seems promising for the accurate identification of psPD, and the technique is amenable to evaluation in larger, multi-centre patient cohorts. PMID- 29193850 TI - Olfactory loss in chronic rhinosinusitis is associated with neuronal activation of c-Jun N-terminal kinase. AB - BACKGROUND: Olfactory inflammation in chronic rhinosinusitis (CRS) is associated with cytokines that may result in the death of olfactory sensory neurons. The principal signaling molecules involved in the apoptotic pathway are c-Jun N terminal kinases (JNK). Although the JNK pathway has emerged as a key player in programmed cell death in neuroinflammation, its specific role in CRS-associated olfactory loss has not been thoroughly investigated. METHODS: JNK activation was studied in human tissue samples from 9 control and 11 CRS patients by immunohistochemical staining for phosphorylated c-Jun. A mouse model of inducible olfactory cytokine expression was used to experimentally control inflammation and assess JNK activation over time. RESULTS: In patients with CRS, activation of c Jun is significantly increased relative to non-CRS control subjects, and there is an associated loss of sensory neurons. In the olfactory inflammation mouse model, prolonged induction of inflammation results in elevation of c-Jun expression and neuronal apoptosis. CONCLUSION: Activation of neuronal JNK is a feature of chronic olfactory inflammation that is associated with neuronal apoptosis. Given that inhibition of JNK activity is neuroprotective in other settings, antagonism of this pathway may have therapeutic potential in the management of inflammatory olfactory loss or other disorders linked to olfactory neuronal apoptosis. PMID- 29193851 TI - Survival of corneal nerve/sheath structures in organ-cultured donor corneas. AB - PURPOSE: To study the morphology of human corneal nerves in eye bank organ cultured corneas and in corneal grafts post-transplantation. METHODS: Thirty seven organ-cultured corneas were divided into: Group-A, anterior 300-400 MUm of 20 corneas used for Descemets stripping endothelial keratoplasty, and Group-B, 17 full-thickness corneas unsuitable for transplantation. Corneas whole mounts were stained for nerves using acetylcholinesterase technique and examined by NanoZoomer digital pathology microscope. Central and sub-Bowman's stromal nerves and the sub-basal nerve plexus including perforation sites and terminal bulbs were studied. Ten eyes were imaged following penetrating keratoplasty using in vivo confocal microscopy (IVCM) for the presence of sub-basal and stromal nerves at 1, 4-5 and 7-8 weeks postoperatively (five eyes) and in all the other five eyes, the final follow-up was at 12 weeks. RESULTS: Fifteen of twenty (75%) corneas had stromal nerves in Group-A and 15 of 17 (88.2%) in Group-B. Average number of stromal nerves entering peripherally were 9.1 (range: 1-36). 7.5 in Group-A and 10.8 in Group-B. Central stromal nerves were seen in eight samples in Group-A and nine in Group-B. Many stromal nerves terminated abruptly without demonstrable continuity through Bowman's membrane. No terminal bulbs or sub-basal nerves were detected. In-vivo confocal microscopy (IVCM) showed 4 of 5 in 9 of 10 (90%) donor corneas had stromal nerves 1 week postoperatively, which remained present in 8 of 10 (80%) corneas at 4-5 weeks and in 9 of 10 (90%) at 7-8 weeks postoperatively. All 5 corneas analysed at 12 weeks showed the same stromal nerves from 1 to 12 weeks postoperatively. Sub-basal nerves were absent in all corneas over the 12-week study period. CONCLUSION: This study provides further insight into the behaviour of corneal nerves in transplanted corneas. Corneal stromal nerves/nerve-sheaths are preserved in organ-cultured eye bank eyes and persist post-transplantation up to 3 months. These could provide directional guidance to regenerating nerves from host stroma. PMID- 29193852 TI - Frequency-Domain Response Analysis for Quantitative Systems Pharmacology Models. AB - Drug dosing regimen can significantly impact drug effect and, thus, the success of treatments. Nevertheless, trial and error is still the most commonly used method by conventional pharmacometric approaches to optimize dosing regimen. In this tutorial, we utilize four distinct classes of quantitative systems pharmacology models to introduce frequency-domain response analysis, a method widely used in electrical and control engineering that allows the analytical optimization of drug treatment regimen from the dynamics of the model.

AB - Plasmodium vivax is a protozoan parasite that is one of the causative agents of human malaria. Due to several occult features of its life cycle, P. vivax threatens to be a problem for the recent efforts toward elimination of malaria globally. With an emphasis on malaria elimination goals, the authors summarize the major gaps in P. vivax diagnosis and describe how proteomics technologies have begun to contribute toward the discovery of antigens that could be used for various technology platforms and applications. The authors suggest areas where, in the future, proteomics technologies could fill in gaps in P. vivax diagnosis that have proved difficult. The discovery of new parasite antigens, host responses, and immune signatures using proteomics technologies will be a key part of the global malaria elimination efforts. PMID- 29193855 TI - Sulfanilic acid-modified chitosan mini-spheres and their application for lysozyme purification from egg white. AB - A cation exchange matrix with zwitterionic and multimodal properties was synthesized by a simple reaction sequence coupling sulfanilic acid to a chitosan based support. The novel chromatographic matrix was physico-chemically characterized by ss-NMR and zeta potential, and its chromatographic performance was evaluated for lysozyme purification from diluted egg white. The maximum adsorption capacity, calculated according to Langmuir adsorption isotherm, was 50.07 +/- 1.47 mg g-1 while the dissociation constant was 0.074 +/- 0.012 mg mL-1 . The process for lysozyme purification from egg white was optimized, with 81.9% yield and a purity degree of 86.5%, according to RP-HPLC analysis. This work shows novel possible applications of chitosan based materials. The simple synthesis reactions combined with the simple mode of use of the chitosan matrix represents a novel method to purify proteins from raw starting materials.

AB - The ear can be subdivided into three distinct parts, each with significantly distinct structural and functional differences, the outer, middle, and inner ear, the latter housing the specialized sensory hair cells that act as transducers. There are numerous manuscripts documenting the anatomical development of the inner, middle, and outer ear in humans, rodents, chick, and zebrafish, dating back to the early 20th Century, and these developmental processes of these components are further compared in a number of review articles (Anthwal & Thompson, ; Basch, Brown, Jen, & Groves, ; Sai & Ladher, ). This article presents a review of both pre- and postnatal development of the inner ear, discusses recent molecular genetic advances toward our understanding of hair cells responsible for the sensory functions of the inner ear. Finally, a survey of comparative ear biology is used to pull together our understanding of the species differences, similarities, and key time points of definitive organ development of the ear. PMID- 29193856 TI - Physical forces modulate cell differentiation and proliferation processes. AB - Currently, the predominant hypothesis explains cellular differentiation and behaviour as an essentially genetically driven intracellular process, suggesting a gene-centrism paradigm. However, although many living species genetic has now been described, there is still a large gap between the genetic information interpretation and cell behaviour prediction. Indeed, the physical mechanisms underlying the cell differentiation and proliferation, which are now known or suspected to guide such as the flow of energy through cells and tissues, have been often overlooked. We thus here propose a complementary conceptual framework towards the development of an energy-oriented classification of cell properties, that is, a mitochondria-centrism hypothesis based on physical forces-driven principles. A literature review on the physical-biological interactions in a number of various biological processes is analysed from the point of view of the fluid and solid mechanics, electricity and thermodynamics. There is consistent evidence that physical forces control cell proliferation and differentiation. We propose that physical forces interfere with the cell metabolism mostly at the level of the mitochondria, which in turn control gene expression. The present perspective points towards a paradigm shift complement in biology. PMID- 29193858 TI - Exophiala phaeomuriformis keratitis in a subarctic climate region: a case report. AB - PURPOSE: To report a case of Exophiala phaeomuriformis mycotic keratitis in a patient from a subarctic climate region. Dematiaceous fungi (black yeasts) have been gaining importance as corneal keratitis and ulcer causative agents in certain regions, but no cases have been described in Scandinavia. METHODS: Case report of a patient with a persistent corneal erosion that eventually presented a brown-pigmented infiltrate. The patient had a history of several months of topical therapy comprising medication for glaucoma, corticosteroids and antibiotics. A therapeutic contact lens was used, and amniotic membrane transplantation was performed before the development of the pigmented infiltrate. RESULTS: Exophiala phaeomuriformis was identified on the microbiological cultures from the surgically obtained infiltrate scrapes. The patient responded to topical amphotericin and fluconazole, the erosion was cured and a stromal scar subsided. During follow-up, sequential slit-lamp images and anterior segment optical coherence tomography (OCT) scans were obtained. CONCLUSION: This is the first described case of keratitis caused by E. phaeomuriformis in a subarctic region, the first in Europe and, to our knowledge, the second reported case in the literature. It is important to remember that superficial corneal brown-pigmented infiltrates should raise the suspicion of an unusual fungal infection even in this climate. This is particularly important in patients with ocular surface disease treated with steroids and antibiotics for a long time. PMID- 29193859 TI - Comparative evaluation of salivary hepatocyte growth factor in smokers and non smokers with chronic periodontitis. AB - AIM: Hepatocyte growth factor (HGF) is a multifunctional cytokine with a wide range of actions, and plays a role in periodontal disease (PD) progression. Smoking significantly increases the risk for PD progression. Thus, aim of the present study was to estimate salivary HGF levels of non-smokers and smokers with chronic periodontitis (CP) and to compare its levels before and after therapy. METHODS: A total of 75 participants were recruited and divided into three groups: group 1 included 25 healthy participants, group 2 included 25 non-smokers with CP, and group 3 included 25 smokers with CP. Salivary HGF levels were estimated by enzyme-linked immunosorbent assay and correlated with clinical parameters before and after treatment. RESULTS: Salivary HGF levels of non-smokers and smokers with CP were significantly higher than the control group. There was a significant reduction in salivary HGF in smokers and non-smokers with CP after non-surgical periodontal therapy (NSPT). CONCLUSION: Salivary HGF levels positively correlated with PD progression and smoking status. A significant reduction in HGF levels was seen after NSPT. Thus, within limits, it can be suggested that HGF plays a role in PD progression and can be used as a diagnostic biomarker to detect disease activity. Salivary HGF levels could also be useful to monitor response to periodontal therapy. PMID- 29193860 TI - Higher Coronary Plaque Burden in Psoriatic Arthritis Is Independent of Metabolic Syndrome and Associated With Underlying Disease Severity. AB - OBJECTIVE: To examine the effect of metabolic syndrome and psoriatic disease related variables on coronary plaque burden in psoriatic arthritis (PsA) patients. METHODS: Fifty PsA patients without symptoms of coronary artery disease (CAD) (25 with metabolic syndrome and 25 without metabolic syndrome) and 50 age- and sex-matched controls underwent 64-slice coronary computed tomography angiography. Plaque localization, segment involvement score (SIS), segment stenosis score (SSS), and total plaque volume (TPV) were calculated. Plaques were classified as calcified, mixed, or noncalcified. Kruskal-Wallis test, rank correlations, and linear regression analyses were used to study the relationship between PsA, metabolic syndrome, and plaque burden. RESULTS: Plaques were found in 76% of PsA patients versus 44% of controls (P = 0.001), and a higher proportion of patients with PsA had affected coronary vessels (P = 0.007). SIS, SSS, and TPV were greater in PsA patients than controls (P = 0.003, P = 0.001, and P <= 0.001, respectively). More PsA patients had mixed plaques, and mixed plaque volume was higher than in controls (P < 0.001). PsA patients with metabolic syndrome and those without metabolic syndrome had similar plaque burdens and types. SIS, SSS, and TPV did not show significant relationships with features of metabolic syndrome, but did significantly correlate with disease activity measures. TPV was associated with a diagnosis of PsA (B = 0.865, P = 0.008), but not with metabolic syndrome. Age, highest C-reactive protein level, highest swollen joint count, disease duration, and plasma glucose level were independent predictors of higher plaque burden in PsA. CONCLUSION: PsA is associated with accelerated coronary plaque formation, particularly mixed plaques, independent of metabolic disease. Psoriatic disease activity and severity may predict coronary plaque burden better than traditional risk factors. PMID- 29193861 TI - The adenosine A2A receptor agonist, CGS 21680, attenuates a probabilistic reversal learning deficit and elevated grooming behavior in BTBR mice. AB - : Restricted interests and repetitive behaviors (RRBs) are a defining feature of autism spectrum disorder (ASD). To date there are limited options for treating this core symptomology. Treatments that stimulate adenosine A2A receptors may represent a promising approach for reducing RRBs in ASD. This is because A2A receptors are expressed on striatal neurons of the basal ganglia indirect pathway. Under activation of this pathway has been associated with RRBs while activation of A2A receptors leads to increased activity of the indirect basal ganglia pathway. The present studies investigated whether acute, systemic treatment with CGS21680, an A2A receptor agonist attenuates elevated self grooming and a probabilistic reversal learning deficit in the BTBR T+ Itpr3tf /J (BTBR) mouse model of idiopathic autism. The effects of this treatment were also investigated in C57BL/6J (B6) mice as a comparison strain. Using a spatial reversal learning test with 80/20 probabilistic feedback, comparable to one in which ASD individuals exhibit deficits, CGS 21680 (0.005 and 0.01mg/kg) attenuated a reversal learning deficit in BTBR mice. Enhancement in probabilistic reversal learning performance resulted from CGS 21680 improving the consistent maintenance of new adaptive behavioral choice patterns after reversal. CGS 21680 at 0.01 mg, but not 0.005 mg, also reduced self-grooming behavior in BTBR mice. CGS 21680 did not affect self-grooming or reversal learning in B6 mice. These findings demonstrate that A2A receptor agonists may be a promising receptor target in the treatment of RRBs in ASD. Autism Res 2018, 11: 223-233. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The present experiments determined whether the drug, CGS 21680, that facilitates activation of adenosine A2A receptors in the brain, would reduce repetitive and inflexible behaviors in the BTBR mouse model of idiopathic autism. CGS 21680 treatment in BTBR mice reduced repetitive and inflexible behaviors. In the control C57BL/6J (B6) mouse strain, CGS 21680 did not affect performance. These findings suggest that stimulation of brain adenosine A2A receptors may be a promising therapeutic strategy in ASD.

PMID- 29193863 TI - Sublethal effects of subzero temperatures on the light brown apple moth, Epiphyas postvittana: fitness costs in response to partial freezing. AB - Population responses to environmental extremes often dictate the bounds to species' distributions. However, population dynamics at, or near, those range limits may also be affected by sublethal effects. We exposed late instars and pupae of an invasive leafroller, Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae), to cold temperatures and measured the effects of exposure on subsequent survivorship, development, and reproduction. Cold temperature was applied as acute exposure to -10 degrees C (a low, but not immediately lethal temperature for this species) or the onset of freezing (the peak of the supercooling point exotherm). Survival was defined as the ability to successfully eclose as an adult. We measured immature development times, pupal mass, and adult longevity as proxies of fitness in survivors. Additionally, surviving insects were mated with individuals that had not been exposed to cold to measure fertility. There was no difference between the proportion of larvae or pupae that survived acute exposure to -10 degrees C and those exposed to the control temperature. Approximately 17% of larvae and 8% of pupae survived brief periods with internal ice formation and continued development to become reproductively viable adults. Importantly, surviving the onset of freezing came with significant fitness costs but not to exposure to -10 degrees C; most insects that survived partial freezing had lower fertility and shorter adult lifespans than either the 10 degrees C or control group. These results are discussed within the context of forecasting invasive insect distributions. PMID- 29193864 TI - Are the spin doctors winning? PMID- 29193865 TI - Maternal Chlamydia infection during pregnancy among younger mothers and risk of gastroschisis in singleton offspring. AB - BACKGROUND: Prevalence of gastroschisis has been increasing in the United States (US) since 1980s. Genital infection with Chlamydia has also been increasing in prevalence, particularly among younger women. The etiology of gastroschisis is unknown. Ongoing research suggests multiple causal factors may be involved, including Chlamydia infection in mothers during pregnancy. METHODS: Using birth certificate data from 2014 US vital records, we conducted a population-based case control study to examine the association between prenatal Chlamydia exposure in young women (16-25 years of age) and gastroschisis in singleton offspring. Cases consisted of live births with gastroschisis, and controls had no major birth defects reported in their birth certificate. Logistic regression analysis was used to estimate crude and adjusted odds ratios (cOR and aOR) and 95% confidence intervals (CI). RESULTS: There were 809 cases (95.6% were isolated cases) and 1,260,293 controls. Chlamydia during pregnancy was reported in 4.5% of case and 3.6% control mothers (p = .21). Case mothers were significantly more likely to be younger (16-20 years of age) at the time of delivery compared to control mothers (p < .0001). We found no significant association between Chlamydia infection during pregnancy and gastroschisis (cOR = 1.24; 95% CI = 0.89-1.73 and aOR = 1.06; 95% CI: 0.66-1.70). CONCLUSION: With the caveat of possible misclassification of exposure and outcome variables in birth certificate data, we found no significant association between prenatal exposure to Chlamydia and gastroschisis in the offspring born to younger mothers. Future studies should refine measures by focusing on relevant risk period and biomarkers. PMID- 29193866 TI - Revisit the Cavernous Sinus from Fetus to Adult-New and Old Data. AB - This article highlighted three advances in the study of the cavernous sinus: (1) the initial formation of the sinus reticulum in early development of the sphenoid bone before ossification (2) extension of reticulum of the sinus and connection with other venules, and (3) the cavernous sinus and the nerves evolved inside this sinus during gestation, for example, the trigeminal nerve already formed bundles of motor and parasympathetic components during fetal development. This ontogenetic study further confirmed the cavernous sinus is not a single or a dual set of sinuses, but a group of extensions of venous sinuses or sinusoids. These new insights were integrated with previous understandings of the cavernous sinus to form this review article. Anat Rec, 301:819-824, 2018. (c) 2017 Wiley Periodicals, Inc. PMID- 29193867 TI - Improved safety margin for embryotoxicity in rats for the new endoperoxide artefenomel (OZ439) as compared to artesunate. AB - BACKGROUND: Combination medicines including an artemisinin are the mainstay of antimalarial therapy. Artemisinins are potent embryotoxicants in animal species due to their trioxane moiety. METHODS: As part of its development, the new synthetic trioxolane antimalarial artefenomel (OZ439) was tested in rat whole embryo culture and in rat embryo-fetal toxicity studies with dosing throughout organogenesis or with a single dose on Gestational Day (GD) 12. The single-dose studies included groups treated with artesunate to allow a direct comparison of the embryotoxicity of the two antimalarials and included toxicokinetics hematology and histological examination of embryos. In addition, the distribution of artefenomel-related material in plasma was determined after the administration of 14 C-artefenomel. RESULTS: Artefenomel and artesunate showed similar patterns of embryotoxicity including cardiovascular defects and resorption with a steep dose-response. They both also caused a depletion of circulating embryonic erythroblasts both in vitro and in vivo and decreases in maternal reticulocyte count. However, artefenomel was ~250-fold less potent than the active metabolite of artesunate (dihydroartemisinin) as an embryotoxicant in vitro. The safety margin (based on AUC) for artefenomel administered on GD 12 was approximately 100 fold greater than that for artesunate. Also, unlike artesunate, artefenomel was not a selective developmental toxicant. CONCLUSIONS: The lesser embryotoxicity of artefenomel is likely linked to its original design which included two blocking side groups that had been introduced to lower the reactivity with ferrous iron. Our data support the hypothesis that artefenomel's improved safety margin is linked to a lower potential for inhibiting heme biosynthesis in embryonic erythroblasts. PMID- 29193868 TI - Xanthomonas axonopodis pv. punicae uses XopL effector to suppress pomegranate immunity. AB - Xanthomonas axonopodis pv. punicae (Xap) causing bacterial blight is an important pathogen that incurs significant losses to the exportability of pomegranate. Xap uses the Xop TTSS-effector, via the type three secretion system, to suppress pomegranate immunity. Here, we investigate the role of XopL during blight pathogenesis. We observed that XopL is essential for its in planta growth and full virulence. Leaves inoculated with Xap DeltaxopL produced restricted water soaked lesions compared to those inoculated with wild-type Xap. XopL supports Xap for its sustained multiplication in pomegranate by suppressing the plant cell death (PCD) event. We further demonstrated that XopL suppresses immune responses, such as callose deposition and production of reactive oxygen species (ROS). RT qPCR analysis revealed that immune responsive genes were upregulated when challenged with Xap DeltaxopL, whereas upregulation of such genes was compromised in the complemented strain containing the xopL gene. The transiently expressed XopL::EYFP fusion protein was localized to the plasma membrane, indicating the possible site of its action. Altogether, this study highlights that XopL is an important TTSS-effector of Xap that suppresses plant immune responses, including PCD, presumably to support the multiplication of Xap for a sufficient time-period during blight disease development. PMID- 29193870 TI - Strain engineering to reduce acetate accumulation during microaerobic growth conditions in Escherichia coli. AB - Microaerobic (oxygen limited) conditions are advantageous for several industrial applications since a majority of the carbon atoms can be directed for synthesis of desired products. Oxygen limited conditions, however, can result in high levels of undesirable by-products such as acetate, which subsequently can have an impact on biomass and product yields. The molecular mechanisms involved in acetate accumulation under oxygen limited conditions are not well understood. Our results indicate that a majority of the genetic modifications known to decrease acetate under aerobic conditions results in similar or even higher acetate under oxygen limitation. Deletion of arcA, whose gene product is a global transcriptional regulator, was the only modification among those evaluated that significantly decreased acetate under both transient and prolonged oxygen limitation. Transcriptome results indicate that the arcA deletion results in an increased expression of the operon involving acs and actP (whose gene products are involved in acetate assimilation and uptake respectively) and some genes in the TCA cycle, thereby promoting increased acetate assimilation. These results provide useful cues for strain design for improved manufacturing of biopharmaceuticals under oxygen limited conditions. (c) 2017 American Institute of Chemical Engineers Biotechnol.

PMID- 29193869 TI - CD4+ and B Lymphocyte Expression Quantitative Traits at Rheumatoid Arthritis Risk Loci in Patients With Untreated Early Arthritis: Implications for Causal Gene Identification. AB - OBJECTIVE: Rheumatoid arthritis (RA) is a genetically complex disease of immune dysregulation. This study sought to gain further insight into the genetic risk mechanisms of RA by conducting an expression quantitative trait locus (eQTL) analysis of confirmed genetic risk loci in CD4+ T cells and B cells from carefully phenotyped patients with early arthritis who were naive to therapeutic immunomodulation. METHODS: RNA and DNA were isolated from purified B and/or CD4+ T cells obtained from the peripheral blood of 344 patients with early arthritis. Genotyping and global gene expression measurements were carried out using Illumina BeadChip microarrays. Variants in linkage disequilibrium (LD) with non HLA RA single-nucleotide polymorphisms (defined as r2 >= 0.8) were analyzed, seeking evidence of cis- or trans-eQTLs according to whether the associated probes were or were not within 4 Mb of these LD blocks. RESULTS: Genes subject to cis-eQTL effects that were common to both CD4+ and B lymphocytes at RA risk loci were FADS1, FADS2, BLK, FCRL3, ORMDL3, PPIL3, and GSDMB. In contrast, those acting on METTL21B, JAZF1, IKZF3, and PADI4 were unique to CD4+ lymphocytes, with the latter candidate risk gene being identified for the first time in this cell subset. B lymphocyte-specific eQTLs for SYNGR1 and CD83 were also found. At the 8p23 BLK-FAM167A locus, adjacent genes were subject to eQTLs whose activity differed markedly between cell types; in particular, the FAM167A effect displayed striking B lymphocyte specificity. No trans-eQTLs approached experiment-wide significance, and linear modeling did not identify a significant influence of biologic covariates on cis-eQTL effect sizes. CONCLUSION: These findings further refine the understanding of candidate causal genes in RA pathogenesis, thus providing an important platform from which downstream functional studies, directed toward particular cell types, may be prioritized.

AB - Tissue engineering scaffolds are designed to mimic physical, chemical, and biological features of the extracellular matrix, thereby providing a constant support that is crucial to improved regenerative medicine outcomes. Beyond mechanical and structural support, the next generation of these materials must also consider the more dynamic presentation and delivery of drugs or growth factors to guide new and regenerating tissue development. These two aspects are explored expansively separately, but they must interact synergistically to achieve optimal regeneration. This review explores common tissue engineering materials types, electrospun polymers and hydrogels, and strategies used for incorporating drug delivery systems into these scaffolds. PMID- 29193872 TI - The Impact of Adhesion Molecules on the In Vitro Culture and Differentiation of Stem Cells. AB - The term "cell adhesion" represents cell-cell interactions and the interaction between the cell and the extracellular matrix (ECM). These interactions are crucial for the development of the stem cells niche to determine stem cell shape. The ECM is considered as a natural niche for cell residence. Cell adhesion molecules (CAMs) enable cell-cell interactions and the interactions between the cell and ECM via various mechanisms, such as trans-interaction and the heterophilic interactions. These interactions promote a broad spectrum of cell signaling that directly or indirectly modulates stem cell proliferation, self renewal property, adhesion, and multilineage differentiation. Over many years, animal-derived feeder layers and culture components have been used for stem cell culture, which produces stem cells unsuitable for clinical applications in the regenerative medicine. This review briefly describes the stages of the development of stem cell culture toward a defined condition and the drawbacks of using animal-derived culture components. Stem cell niche-derived and ECM-derived adhesion molecules and their detailed impact on stem cell adhesion and functions will be discussed. Efficient and novel adhesion molecules for stem cell culture and differentiation are needed for further large-scale applications in tissue regeneration.

AB - We investigate a simple and accurate method for quantitatively analyzing dissolved inorganic carbon in environmental water by reaction headspace gas chromatography. The neutralization reaction between the inorganic carbon species (i.e. bicarbonate ions and carbonate ions) in environmental water and hydrochloric acid is carried out in a sealed headspace vial, and the carbon dioxide formed from the neutralization reaction, the self-decomposition of carbonic acid, and dissolved carbon dioxide in environmental water is then analyzed by headspace gas chromatography. The data show that the headspace gas chromatography method has good precision (relative standard deviation <= 1.63%) and accuracy (relative differences <= 5.81% compared with the coulometric titration technique). The headspace gas chromatography method is simple, reliable, and can be well applied in the dissolved inorganic carbon detection in environmental water. PMID- 29193874 TI - A factorial design to identify process parameters affecting whole mechanically disrupted rat pancreata in a perfusion bioreactor. AB - Few studies report whole pancreatic tissue culture, as it is a difficult task using traditional culture methods. Here, a factorial design was used to investigate the singular and combinational effects of flow, dissolved oxygen concentration (D.O.) and pulsation on whole mechanically disrupted rat pancreata in a perfusion bioreactor. Whole rat pancreata were cultured for 72 h under defined bioreactor process conditions. Secreted insulin was measured and histological (haematoxylin and eosin (H&E)) as well as immunofluorescent insulin staining were performed and quantified. The combination of flow and D.O. had the most significant effect on secreted insulin at 5 h and 24 h. The D.O. had the biggest effect on tissue histological quality, and pulsation had the biggest effect on the number of insulin-positive structures. Based on the factorial design analysis, bioreactor conditions using high flow, low D.O., and pulsation were selected to further study glucose-stimulated insulin secretion. Here, mechanically disrupted rat pancreata were cultured for 24 h under these bioreactor conditions and were then challenged with high glucose concentration for 6 h and high glucose + IBMX (an insulin secretagogue) for a further 6 h. These cultures secreted insulin in response to high glucose concentration in the first 6 h, however stimulated-insulin secretion was markedly weaker in response to high glucose concentration + IBMX thereafter. After this bioreactor culture period, higher tissue metabolic activity was found compared to that of non bioreacted static controls. More insulin- and glucagon-positive structures, and extensive intact endothelial structures were observed compared to non-bioreacted static cultures. H&E staining revealed more intact tissue compared to static cultures. (c) 2017 American Institute of Chemical Engineers Biotechnol. Prog., 34:432-444, 2018. PMID- 29193875 TI - Dabigatran inhibits intravitreal thrombin activity. AB - PURPOSE: Proliferative vitreoretinopathy (PVR) is a vitreoretinal disorder in which retinal pigment epithelial (RPE) cell activation contributes to both formation of fibrotic retinal membranes and inflammation. Vitreous of patients with PVR contains increased thrombin activity which induces profibrotic and proinflammatory programs in RPE cells. Inhibition of intravitreal thrombin activity may thus represent a therapeutic option for PVR. In this study, we examined the capacity of the clinically available direct thrombin inhibitor dabigatran to inhibit thrombin activity in vitreous fluids. METHODS: ARPE-19 cells were cultured with the following: (i) thrombin, (ii) vitreous without thrombin activity and (iii) vitreous with elevated thrombin activity (PVR samples and thrombin spiked vitreous) either in the presence or absence of dabigatran (range: 10-5 to 10-7 M). Subsequently, CCL2, CXCL8, GMCSF, IL6 and PDGFB mRNA expression levels were determined by RQ-PCR and protein levels of 27 cytokines, chemokines and growth factors were detected in culture supernatants using a multiplex approach. In addition, the capacity of vitreous fluids obtained from patients after oral dabigatran intake was tested in an in vitro thrombin activity assay. RESULTS: Thrombin and vitreous fluids containing thrombin activity induced CCL2, CXCL8, GM-CSF, IL-6 and PDGF-BB expression by ARPE-19 cells, which was inhibited by dabigatran. In addition, dabigatran that reached the vitreous after repeated oral intake did inhibit thrombin activity in the in vitro activity assay. CONCLUSION: Proliferative vitreoretinopathy (PVR) is associated with increased intravitreal thrombin activity that activates profibrotic and proinflammatory pathways in RPE cells. Our findings provide evidence that this activation pathway can potentially be inhibited by dabigatran.

AB - Cell functionalization with recently developed various nano- and microcarriers for therapeutics has significantly expanded the application of cell therapy and targeted drug delivery for the effective treatment of a number of diseases. The aim of this progress report is to review the most recent advances in cell-based drug vehicles designed as biological transporter platforms for the targeted delivery of different drugs. For the design of cell-based drug vehicles, different pathways of cell functionalization, such as covalent and noncovalent surface modifications, internalization of carriers are considered in greater detail together with approaches for cell visualization in vivo. In addition, several animal models for the study of cell-assisted drug delivery are discussed. Finally, possible future developments and applications of cell-assisted drug vehicles toward targeted transport of drugs to a designated location with no or minimal immune response and toxicity are addressed in light of new pathways in the field of nanomedicine. PMID- 29193877 TI - Effects of probiotics on ghrelin and lungs in children with acute lung injury: A double-blind randomized, controlled trial. AB - AIM: To assess the effects of probiotics on serum ghrelin levels and protection for lungs in children with acute lung injury (ALI). METHODS: This study was performed as a double-blind, randomized, and controlled trial in a pediatric intensive care unit (PICU). The eligible children with ALI were assigned to either probiotic treatment or an identical placebo for 10 days. Serum ghrelin, SP A(surfactant protein-A), TNF-alpha, and IL-6 concentrations were assessed at baseline and at the end of trial. Meanwhile, pulmonary function test and echocardiography were examined, then VPEF (volume to peak tidal expiratory flow), TPEF/TE (the ratio of time taken to reach peak expiratory flow to total expiratory time), MAP (mean arterial pressure), and PAP (pulmonary artery pressure) were recorded. RESULTS: Eighty participants fulfilled the study requirements with 40 children for each group. The groups were comparable in baseline characteristics. Serum SP-A, TNF-alpha, and IL-6 levels in the probiotic group were 212.6 +/- 52.9 ng/mL, 401.9 +/- 56.4 pg/mL, and 245.1 +/- 55.1 pg/mL on day 10, respectively, significantly lower levels compared to the control group where the same parameters were 248.2 +/- 57 ng/mL, 449.4 +/- 60.1 pg/mL, and 308.3 +/- 92.2 pg/mL (P < 0.01). However, ghrelin concentrations were elevated in the intervention group (P < 0.05). On measurement of pulmonary function, the probiotic group demonstrated a VPEF of 26.1 +/- 4.2 mL and TPEF/TE of 29.1 +/- 4.7%, which were higher than the control group (24.7 +/- 4.3 mL and 26.9 +/- 4.7%, respectively) (P < 0.05). MAP and PAP also improved in the probiotic group (P < 0.05). Furthermore, ghrelin, SP-A, TNF-alpha, IL-6, and PAP were negatively correlated. Positive correlations were found between ghrelin, TPEF/TE, and MAP. There were no probiotic-associated adverse events during the observation. CONCLUSION: Probiotics administrated to children with ALI alleviates the inflammation of lungs, improves pulmonary function and circulation by ghrelin. PMID- 29193878 TI - Development of a transendothelial shuttle by macrophage modification. AB - One of the limiting factors in tissue regeneration, particularly in the context of chronic disease such as myodystrophy, motor neuron disease, sarcopenia, and cardiovascular disease, is limited availability of stem cells. We propose employing autologous macrophages to deliver stem cells, thereby facilitating tissue regeneration, by a novel and relatively non-invasive therapeutic intervention. Circulatory monocytic cells of M1 phenotype have capacity for transendothelial migration to infiltrate damaged tissue, making them ideal delivery vehicles. However, in order to deliver viable stem cells, these macrophages must undergo phagosome maturation arrest. Our aim was to induce phagosome maturation arrest in prepolarised M1 macrophages, whilst maintaining capacity for phagocytic engulfment (including phagosome formation) and transendothelial migration. Primary human M1 macrophages were treated with a wortmannin-concanamycin A-chloroquine cocktail to induce arrest. Modified cells were allowed to ingest 4.5 MUm protein-coated fluorescent latex beads (simulated stem cells), before migratory capacity in response to MCP-1 was assessed over a 2 hr period in a Transwell co-culture system. Data indicate that phagosome acidification (as indicated by pHrodo(r)) was prevented in treated cells, effectively limiting digestion of ingested "cargo" (1.23 +/- 0.26% vs. 7.52 +/- 0.98% in controls; p < .0001). Neither phagocytic engulfment capacity (68.67 +/- 3.51% vs. 61.19 +/- 4.68%) nor migratory capacity (70.14 +/- 12.6 vs. 72.86 +/- 16.0 migrated cells per well) was compromised. We conclude that macrophages were successfully modified into transendothelial delivery vehicles, without compromising required functionality. This delivery system can be exploited to develop a novel method for focussed stem cell and/or drug delivery. PMID- 29193879 TI - Organ Bioprinting: Are We There Yet? AB - About 15 years ago, bioprinting was coined as one of the ultimate solutions to engineer vascularized tissues, which was impossible to accomplish using the conventional tissue fabrication approaches. With the advances of 3D-printing technology during the past decades, one may expect 3D bioprinting being developed as much as 3D printing. Unfortunately, this is not the case. The printing principles of bioprinting are dramatically different from those applied in industrialized 3D printing, as they have to take the living components into account. While the conventional 3D-printing technologies are actually applied for biological or biomedical applications, true 3D bioprinting involving direct printing of cells and other biological substances for tissue reconstruction is still in its infancy. In this progress report, the current status of bioprinting in academia and industry is subjectively evaluated. The progress made is acknowledged, and the existing bottlenecks in bioprinting are discussed. Recent breakthroughs from a variety of associated fields, including mechanical engineering, robotic engineering, computing engineering, chemistry, material science, cellular biology, molecular biology, system control, and medicine may overcome some of these current bottlenecks. For this to happen, a convergence of these areas into a systemic research area "3D bioprinting" is needed to develop bioprinting as a viable approach for creating fully functional organs for standard clinical diagnosis and treatment including transplantation. PMID- 29193880 TI - Octyl ester of ginsenoside compound K as novel anti-hepatoma compound: Synthesis and evaluation on murine H22 cells in vitro and in vivo. AB - Ginsenoside compound K (M1) is the active form of major ginsenosides deglycosylated by intestinal bacteria after oral administration. However, M1 was reported to selectively accumulate in liver and transform to fatty acid esters. Ester of M1 was not excreted by bile as M1 was, which means it was accumulated in the liver longer than M1. This study reported a synthetic method of M1-O, a mono octyl ester of M1, and evaluated the anticancer property against murine H22 cell both in vitro and in vivo. As a result, both M1 and M1-O showed a dose-dependent manner in cytotoxicity assay in vitro. At lower dose of 12.5 MUm, M1-O showed moderate detoxification. Instead, M1-O exhibited significantly higher inhibition in H22-bearing mice than M1. M1-O induced murine H22 tumor cellular apoptosis in caspase-dependent pathway given that pan-caspase inhibitor, Z-VAD-FMK, could reverse the cytotoxicity induced by M1-O. Additionally, pro- and anti-apoptosis proteins, Bcl-2 and Bax, altered and consequently induced increased expression of cleaved caspase-3. Interestingly, cyclophosphamide regimen significantly induced atrophy of spleen and thymus, main immune organs, while M1-O treatment greatly alleviated this atrophy. Collectively, we propose M1-O as a candidate for live cancer treatment. PMID- 29193881 TI - Parent knowledge of disease management in cystic fibrosis: Assessing behavioral treatment management. AB - BACKGROUND: Cystic fibrosis (CF) is a life-shortening, burdensome disease requiring complex knowledge to manage the disease. Significant gaps in knowledge have been documented for parents, which may lead to unintentionally poor adherence and insufficient transfer of treatment responsibility from parents to adolescents. There are no current, validated measures of parent knowledge for this population and there are no measures that assess the knowledge required for day-to-day behavioral management of CF. We assessed the psychometric properties of the parent version of the Knowledge of Disease Management-Cystic Fibrosis measure (KDM-CF-P) using data from iCARE (I Change Adherence and Raise Expectations), a randomized control adherence intervention trial. METHODS: A total of 196 parents in the iCARE standard care/control arm completed 35 items assessing their knowledge of disease management at their 12-month study visit, prior to beginning the intervention. Items were eliminated from the measure if they met the threshold for ceiling effects, were deemed clinically irrelevant, or did not correlate well with their intended scale. Item-to-total correlations, confirmatory factor analysis, discriminant function, reliability, and convergent validity were calculated. RESULTS: The KDM-CF-P (19 items) demonstrated internal consistency of KR20 = 0.60 on each scale and a two-scale structure. Convergent validity for knowledge scores was found with maternal education, family income, and type of medical insurance. Parents correctly answered approximately 85% of items on the KDM-CF-P. CONCLUSIONS: The KDM-CF-P psychometrics support a two scale measure with clinical utility. It is useful for assessing gaps in knowledge that can be remediated through individualized, tailored interventions. PMID- 29193882 TI - Giant cell tumor of temporomandibular joint presenting as a parotid tumor: Challenges in the accurate subclassification of giant cell tumors in an unusual location. AB - Fine needle aspiration is frequently used as the initial diagnostic procedure in the work-up of head and neck lesions, including soft tissue masses and salivary gland neoplasms. Giant cell tumors (GCTs), both osseous and extraosseous, are benign tumors that occur, albeit rarely, in the head and neck region. Extraosseous GCTs may be further classified based on their tissue of origin and specific anatomic location. Regardless of location, giant cell tumors are morphologically similar and share cytologic and histologic diagnostic criteria. Evaluation of imaging is therefore essential to the correct classification of these tumors. Accurate diagnosis is crucial since the clinical behavior and treatment is significantly different among the subtypes of GCTs. The case presented herein illustrates the diagnostic dilemma between two uncommon entities in an unusual site: GCT of parotid gland and tenosynovial GCT. PMID- 29193884 TI - Morphological and clinical evaluation of prostatic urethra using modified sonourethrography with retrograde jelly injection. AB - OBJECTIVE: Using modified sonourethrography (mSUG) with retrograde jelly injection to precisely measure the morphological characteristics of the prostatic urethra, we assessed prostatic urethral morphology associated with clinical parameters of benign prostatic hyperplasia (BPH). METHODS: BPH patients (n = 43) and control patients with localized prostate cancer (PC; n = 57) were imaged by mSUG before surgery. Using the seminal colliculus as a landmark, prostatic urethral angulation (PUA), sagittal urethral diameter, and anterior or posterior prostatic urethral length were measured. The International Prostatic Symptoms Score (IPSS) was also evaluated in all patients. The Bladder Outlet Obstruction Index (BOOI) was measured in BPH patients that could void in a pressure-flow study. Parameters were compared between BPH and PC patients, and correlations among morphological and clinical parameters were evaluated. RESULTS: Prostatic urethras were clearly observed in all patients by mSUG. PUA, sagittal urethral diameter, and posterior urethral length were all greater in BPH than PC patients (P < .05). Among all parameters examined, PUA had the strongest correlation with IPSS (r = 0.56). Longitudinal urethral diameter showed the strongest correlation with BOOI, whereas PUA was not correlated with BOOI. CONCLUSIONS: Prostatic urethral morphology can be imaged precisely by mSUG. Morphometric measurements showed that increased PUA was strongly correlated with problematic urinary symptoms, and a flattened shape of the posterior urethra, such as extension of the sagittal urethral diameter, was correlated with urinary tract obstruction by BPH. PMID- 29193885 TI - AquaMMapS: An Alternative Tool to Monitor the Role of Water Molecules During Protein-Ligand Association. AB - Unquestionably, water appears to be an active player in the noncovalent protein ligand binding process, as it can either bridge interactions between protein and ligand or can be replaced by the bound ligand. Accordingly, in the last decade, alternative computational methodologies have been sought with the aim of predicting the position and thermodynamic profile of water molecules (i.e., hydration sites) in the binding site using either the ligand-bound or ligand-free protein conformation. Herein, we present an alternative approach, named AquaMMapS, that provides a three-dimensional sampling of putative hydration sites. Interestingly, AquaMMapS can post-inspect molecular dynamics (MD) trajectories obtained from different MD engines using indifferently crystallographic or docking-driven structures as a starting point. Moreover, AquaMMapS is naturally integrated into supervised molecular dynamics (SuMD) simulations, presenting the possibility to inspect hydration sites during the ligand-protein association process. Finally, a penalty scoring method, named AquaMMapScoring(AMS), was developed to evaluate the number and nature of the water molecules displaced by a ligand approaching its binding site during the binding event, guiding a medicinal chemist to explore the most suitable regions of a ligand that can be decorated either with or without interfering with the interaction networks mediated by water molecules with specific recognition regions of the protein. PMID- 29193883 TI - Economic Evaluation of Lupus Nephritis in the Systemic Lupus International Collaborating Clinics Inception Cohort Using a Multistate Model Approach. AB - OBJECTIVE: Little is known about the long-term costs of lupus nephritis (LN). The costs were compared between patients with and without LN using multistate modeling. METHODS: Patients from 32 centers in 11 countries were enrolled in the Systemic Lupus International Collaborating Clinics inception cohort within 15 months of diagnosis and provided annual data on renal function, hospitalizations, medications, dialysis, and selected procedures. LN was diagnosed by renal biopsy or the American College of Rheumatology classification criteria. Renal function was assessed annually using the estimated glomerular filtration rate (GFR) or estimated proteinuria. A multistate model was used to predict 10-year cumulative costs by multiplying annual costs associated with each renal state by the expected state duration. RESULTS: A total of 1,545 patients participated; 89.3% were women, the mean +/- age at diagnosis was 35.2 +/- 13.4 years, 49% were white, and the mean followup duration was 6.3 +/- 3.3 years. LN developed in 39.4% of these patients by the end of followup. Ten-year cumulative costs were greater in those with LN and an estimated glomerular filtration rate (GFR) <30 ml/minute ($310,579 2015 Canadian dollars versus $19,987 if no LN and estimated GFR >60 ml/minute) or with LN and estimated proteinuria >3 gm/day ($84,040 versus $20,499 if no LN and estimated proteinuria <0.25 gm/day). CONCLUSION: Patients with estimated GFR <30 ml/minute incurred 10-year costs 15-fold higher than those with normal estimated GFR. By estimating the expected duration in each renal state and incorporating associated annual costs, disease severity at presentation can be used to anticipate future health care costs. This is critical knowledge for cost-effectiveness evaluations of novel therapies. PMID- 29193886 TI - Association between severe nausea and vomiting in early pregnancy and the risk of neural tube defects in Northern China. AB - BACKGROUND: This study assessed the association between severe NVP and the risk of NTD in offspring compared with a population and a malformed control group. We also assessed whether folic acid supplements modified this association. STUDY DESIGN AND SETTING: A case-control study was conducted with subjects enrolled from June 19, 2002, to November 18, 2014, from a population-based birth defects surveillance system that monitors major external structural birth defects through active case ascertainment in Shanxi Province, China. The main comparison was between women with NTD-affected offspring who experienced NVP in early pregnancy versus those who did not. A multivariable logistic regression model was used to examine the associations between severe NVP and the risk of NTD while adjusting for potential confounding factors. The risk was estimated by calculating the odds ratio (OR) and 95% confidence intervals (CIs). RESULTS: The adjusted OR (AOR) of severe NVP for NTDs was 3.25 (95%CI 2.56, 4.12) compared with the population control, and 1.65 (95%CI 1.00, 2.72) compared with the malformed controls. When stratified by intake of folic acid supplements, the AOR for severe NVP was 3.40 (95%CI 2.61, 4.42) in the non-intake of folic acid supplements stratum and 2.51 (95%CI 1.42, 4.43) in the intake of folic acid supplements stratum. CONCLUSION: We conclude that severe NVP is associated with NTDs, and that severe NVP may be a consequence, rather than a cause, of NTDs. PMID- 29193887 TI - Systems Pharmacology of VEGF165b in Peripheral Artery Disease. AB - We built a whole-body computational model to study the role of the poorly understood vascular endothelial growth factor (VEGF)165b splice isoform in peripheral artery disease (PAD). This model was built and validated using published and new experimental data from cells, mice, and humans, and explicitly accounts for known properties of VEGF165b : lack of extracellular matrix (ECM) binding and weak phosphorylation of vascular endothelial growth factor receptor-2 (VEGFR2) in vitro. The resulting model captures all known information about VEGF165b distribution and signaling in human PAD, and provides novel, nonintuitive insight into VEGF165b mechanism of action in vivo. Although VEGF165a and VEGF165b compete for VEGFR2 in vitro, simulations show that these isoforms do not compete for VEGFR2 at much lower physiological concentrations. Instead, reduced VEGF165a may drive impaired VEGFR2 signaling. The model predicts that VEGF165b does compete for binding to VEGFR1, supporting a VEGFR1-mediated response to anti-VEGF165b . The model predicts a key role for VEGF165b in PAD, but in a different way than previously hypothesized. PMID- 29193888 TI - Associations Between Slower Walking Speed and T1rho Magnetic Resonance Imaging of Femoral Cartilage Following Anterior Cruciate Ligament Reconstruction. AB - OBJECTIVE: To determine whether walking speed, collected at 6 and 12 months following anterior cruciate ligament reconstruction (ACLR), is associated with inter-extremity differences in proteoglycan density, measured via T1rho magnetic resonance imaging, in tibiofemoral articular cartilage 12 months following ACLR. METHODS: Twenty-one individuals with a unilateral patellar-tendon autograft ACLR (10 women and 11 men, mean +/- SD age 23.9 +/- 2.7 years, mean +/- SD body mass index 23.9 +/- 2.7 kg/m2 ) were recruited for participation in this study. Walking speed was collected using 3-dimensional motion capture at 6 and 12 months following ACLR. The articular cartilage of the medial femoral condyle (MFC) and lateral femoral condyle and medial and lateral tibial condyles was manually segmented and subsectioned into 3 regions of interest (anterior, central, and posterior) based on the location of the meniscus in the sagittal plane. Inter extremity mean T1rho relaxation time ratios (T1rho ACLR extremity / T1rho contralateral extremity) were calculated and used for analysis. Pearson product moment correlations were used to determine associations between walking speed and inter-extremity differences in T1rho relaxation time ratios. RESULTS: Slower walking speed 6 months post-ACLR was significantly associated with higher T1rho relaxation time ratios in the MFC of the ACLR extremity 12 months following ACLR (posterior MFC, r = -0.51, P = 0.02; central MFC, r = -0.47, P = 0.04). Similarly, slower walking speed at 12 months post-ACLR was significantly associated with higher T1rho relaxation time ratios in the posterior MFC ACLR extremity (r = -0.47, P = 0.04) 12 months following ACLR. CONCLUSION: Slower walking speed at 6 and 12 months following ACLR may be associated with early proteoglycan density changes in medial femoral compartment cartilage health in the first 12 months following ACLR.

PMID- 29193892 TI - Association of Defective Regulation of Autoreactive Interleukin-6-Producing Transitional B Lymphocytes With Disease in Patients With Systemic Sclerosis. AB - OBJECTIVE: Systemic sclerosis (SSc) has the highest case-specific mortality of any rheumatic disease, and no effective therapy is available. A clear manifestation of SSc is the presence of autoantibodies. However, the origin of autoantibody-producing B lymphocytes, their mechanisms of activation and autoantibody production, and their role remain unclear. This study was undertaken to identify mechanisms that contribute to pathogenic B cell generation and involvement in SSc and to assess the altered distribution and function of B cells in SSc patients. METHODS: Multicolor flow cytometry was performed to determine B cell subset distribution, cytokine production, and tolerance induction in SSc patients and healthy controls. Cytokine production following stimulation of the cells ex vivo was determined by multiplex assay. RESULTS: A range of defects in B lymphocyte tolerance and cytokine production in SSc were noted. There was evidence of altered distribution of transitional B cell subsets, increased production of interleukin-6 (IL-6) and IL-8, and defective tolerance induction in SSc B cells. In addition, B cells from SSc patients had a reduced ability to produce IL-10 when stimulated through innate immune pathways. In contrast to healthy individuals, tolerance checkpoints in SSc patients failed to suppress the emergence of B cells that produce autoantibodies with specificity to the Scl-70 antigen, which is strongly associated with SSc. These defects were paralleled by altered intracellular signaling and apoptosis following B cell receptor engagement. CONCLUSION: Our findings provide new insights into mechanisms underlying defective B lymphocyte responses in patients with SSc and their contribution to disease. PMID- 29193893 TI - Sex Differences in Health Care Utilization, End-Stage Renal Disease, and Mortality Among Medicaid Beneficiaries With Incident Lupus Nephritis. AB - OBJECTIVE: While systemic lupus erythematosus and lupus nephritis (LN) disproportionately affect females, previous studies suggest that males may experience poorer outcomes. We undertook this study to investigate sex differences in health care utilization, end-stage renal disease (ESRD), and mortality among patients with LN receiving Medicaid, public insurance for low income individuals. METHODS: Within the Medicaid Analytic eXtract (MAX) from 29 states (from 2000 to 2010), we used billing claims to identify individuals ages 5 65 years with incident LN (positive predictive value 80%). MAX data were linked to the US Renal Data System to determine ESRD and to Social Security Death Index files to determine death. We estimated adjusted incidence rate ratios (IRRs) by sex for health care utilization using Poisson regression, and we used multivariable proportional hazards models to compare risks of ESRD and death by sex. RESULTS: Of 2,750 patients with incident LN, 283 (10%) were male. The mean +/- SD follow-up period for both sexes was 3.1 +/- 2.3 years. The mean +/- SD age was 29.6 +/- 13.9 years among females and 24.7 +/- 14.1 years among males (P < 0.01). Males had fewer outpatient visits (IRR 0.88 [95% confidence interval (95% CI) 0.80-0.97]) and fewer emergency department visits (IRR 0.75 [95% CI 0.63 0.90]). The 5-year cumulative incidence of ESRD was 22.3% in males and 21.2% in females. The 5-year cumulative incidence of death was 9.4% in males and 9.8% in females. Comparing males to females, there were no sex differences in ESRD (subdistribution hazard ratio [HR] 1.05 [95% CI 0.76-1.45]) or death (HR 0.81 [95% CI 0.47-1.35]). CONCLUSION: In this cohort of patients with incident LN, ESRD and mortality were extremely high overall but were not increased among males compared to females. In this vulnerable population, biologic and health care utilization differences by sex may not significantly affect outcomes. PMID- 29193894 TI - Phenotypic and genotypic comparison of salmonellae from diarrhoeic and healthy humans and cattle, Nigeria. AB - The sources and modes of transmission of non-typhoidal Salmonella particularly zoonotic transmission are poorly understood in Africa. This study compared phenotypic and genotypic characteristics of Salmonellae isolated from cattle and humans. Faecal samples of diarrhoeic patients (n = 234), and a healthy population (n = 160), beef cattle at slaughter (n = 250), farms (n = 72) and market (n = 100) were cultured for salmonellae and serotyping and antimicrobial susceptibility were determined. Whole-genome sequence typing (WGST) of selected isolates and bioinformatic analysis were used to identify the multilocus sequence type (MLST), plasmid replicons, antimicrobial resistance genes and genetic relatedness by single nucleotide polymorphism (SNP) analysis. The Salmonella isolates, diarrhoeic patients (n = 17), healthy population (n = 13), cattle (abattoir, n = 67; farms, n = 10; market n = 5), revealed 49 serovars; some serovars were common to humans and cattle. Rare serovars were prevalent: Colindale (cattle and humans); Rubislaw and Bredeney (humans); and Dublin, Give, Eastbourne, Hadar, Marseille, Sundsvall, Bergen, Ekotedo, Carno and Ealing (cattle). The sequence types (ST) include ST 584, ST 198, ST 562 and ST 512 for S. Colindale, S. Kentucky S. Rubislaw and S. Urbana, respectively. Clonal cluster shared by cattle and human WGST isolates was not found. Antimicrobial resistance rates were generally low and towards only chloramphenicol, ampicillin, gentamicin, ciprofloxacin, tetracycline and streptomycin, range 2.7% (chloramphenicol) to 8.9% (streptomycin). Multiply resistant isolates included serovars Kentucky, 4,5,12:i:- and Typhimurium. The study presents a baseline description of the prevalence, serotypes, antimicrobial resistance phenotypes and genetic relatedness of Salmonella isolated from healthy and diarrhoeic humans, and cattle at harvest, on farm and at market. Cattle are a reservoir of diverse salmonellae with shared serovars with humans, but WGST does not support zoonotic transmission. Further study with larger samples is recommended to determine whether epidemiological link exists between cattle and humans. PMID- 29193895 TI - Inflammatory Cytokines Stabilize SOXC Transcription Factors to Mediate the Transformation of Fibroblast-Like Synoviocytes in Arthritic Disease. AB - OBJECTIVE: Fibroblast-like synoviocytes (FLS) produce key synovial fluid and tissue components to ensure joint integrity under healthy conditions, whereas they become cancer-like and aggressively contribute to joint degeneration in inflammatory arthritis. The aim of this study was to determine whether the SOXC transcription factors SOX4 and SOX11, whose functions are critical in joint development and many cancer types, contribute to FLS activities under normal and inflammatory conditions. METHODS: We inactivated the SOXC genes in FLS from adult mice and studied the effect on joint homeostasis and tumor necrosis factor (TNF) induced arthritis. We used primary cells and synovial biopsy specimens from arthritis patients to analyze the interactions between inflammatory signals and SOXC proteins. RESULTS: Postnatal inactivation of the SOXC genes had no major effect on joint integrity in otherwise healthy mice. However, it hampered synovial hyperplasia and joint degeneration in transgenic mice expressing human TNF. These effects were explained by the ability of SOX4/11 to amplify the pathogenic impact of TNF on FLS by increasing their survival and migration. SOXC RNA levels were not changed by TNF and other proinflammatory cytokines, but SOXC proteins were strongly stabilized and able to potentiate the TNF-induced up regulation of genes involved in FLS transformation. Substantiating the relevance of these findings in human disease, SOXC protein levels, but not RNA levels, were significantly higher in inflamed synovium than in noninflamed synovium from arthritis patients. CONCLUSION: SOXC proteins are targets and pivotal mediators of proinflammatory cytokines during FLS transformation in arthritic diseases. Targeting of these proteins could thus improve current strategies to treat arthritic diseases and possibly other inflammatory diseases. PMID- 29193897 TI - Multilineage Constructs for Scaffold-Based Tissue Engineering: A Review of Tissue Specific Challenges. AB - There is a growing interest in the regeneration of tissue in interfacial regions, where biological, physical, and chemical attributes vary across tissue type. The simultaneous use of distinct cell lineages can help in developing in vitro structures, analogous to native composite tissues. This literature review gathers the recent reports that have investigated multiple cell types of various sources and lineages in a coculture system for tissue-engineered constructs. Such studies aim at mimicking the native organization of tissues and their interfaces, and/or to improve the development of complex tissue substitutes. This paper thus distinguishes itself from those focusing on technical aspects of coculturing for a single specific tissue. The first part of this review is dedicated to variables of cocultured tissue engineering such as scaffold, cells, and in vitro culture environment. Next, tissue-specific coculture methods and approaches are covered for the most studied tissues. Finally, cross-analysis is performed to highlight emerging trends in coculture principles and to discuss how tissue-specific challenges can inspire new approaches for regeneration of different interfaces to improve the outcomes of various tissue engineering strategies.

PMID- 29193896 TI - In utero ultrasound diagnosis of corpus callosum agenesis leading to the identification of orofaciodigital type 1 syndrome in female fetuses. AB - BACKGROUND: OFD1 syndrome is a rare ciliopathy inherited on a dominant X-linked mode, typically lethal in males in the first or second trimester of pregnancy. It is characterized by oral cavity and digital anomalies possibly associated with cerebral and renal signs. Its prevalence is between 1/250,000 and 1/50,000 births. It is due to heterozygous mutations of OFD1 and mutations are often de novo (75%). Familial forms show highly variable phenotypic expression. OFD1 encodes a protein involved in centriole growth, distal appendix formation, and ciliogenesis. CASES: We report the investigation of three female fetuses in which corpus callosum agenesis was detected by ultrasound during the second trimester of pregnancy. In all three fetuses, fetopathological examination allowed the diagnosis of OFD1 syndrome, which was confirmed by molecular analysis. CONCLUSIONS: To our knowledge, these are the first case reports of antenatal diagnosis of OFD1 syndrome in the absence of familial history, revealed following detection of agenesis of the corpus callosum. They highlight the impact of fetal examination following termination of pregnancy for brain malformations. They also highlight the contribution of ciliary genes to corpus callosum development. PMID- 29193899 TI - Role of Cochrane Reviews in informing US private payers' policies. AB - AIM: To assess the use of Cochrane Reviews to inform the medical policy documents of major US private payers. METHODS: The publically available drug policy documents of the five major US private payers (covering about 50% market) namely: Anthem, Aetna, Cigna, Humana and United Healthcare (UHC) were assessed in February 2017 and reviewed to find whether they had used Cochrane Reviews. We extracted information such as use of Cochrane Reviews, number of Cochrane Reviews used, context of use and impact of Cochrane Reviews on policy, and Cochrane Review Group (CRG) and Cochrane Center linked to the Cochrane Review. RESULT: Among the selected payers, less than half of the policy documents used Cochrane Reviews: maximum for Aetna (52%) and minimum for Humana (2%). Three hundred and sixty-one Cochrane Reviews from 42 CRGs have been used to inform 118 drug policy documents: Aetna (221) Anthem (64), Cigna (30), and UHC (25). The highest number of reviews used from any Cochrane Center was 79 (UK). The most reviews used from any CRG were 27 (Musculoskeletal Group). The most reviews used to inform any one policy was 18 (Drug: Botulinum Toxin, Payer: Aetna). Overall, 66% of the Cochrane Reviews were used to inform the background section of the policy document and 34% supported the clinical usage of the drug. Furthermore, 42% of the reviews had cited inline in the policies they were used to inform. CONCLUSION: Cochrane Reviews are used to inform the US healthcare payers' policies, but there is still scope to encourage the further usage of Cochrane Reviews in healthcare decision making. PMID- 29193900 TI - ERRATUM. PMID- 29193901 TI - Hepatitis C virus infection and risk of gallstones: A meta-analysis. AB - BACKGROUND/OBJECTIVES: Gallstones and its complications are one of the most common hepatobiliary tract diseases. Several epidemiologic studies have suggested that patients with hepatitis C virus (HCV) infection might be at an increased risk of gallstones. However, the data on this relationship remain inconclusive. This meta-analysis was conducted with the aims to summarize all available evidence. METHODS: A literature search was performed using MEDLINE and EMBASE databases from inception to May 2016. Studies that reported relative risks, odd ratios, or hazard ratios comparing the risk of gallstones among HCV-infected patients versus subjects without HCV infection were included. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method. RESULTS: Eleven studies met our eligibility criteria and were included in the analysis. The pooled OR of gallstones in HCV infected patients versus subjects without HCV infection was 1.83 (95% CI, 1.35 to 2.48, I2 = 89%). Subgroup analysis showed that significant risk was increased for both male (pooled OR of 2.07, 95% CI, 1.14 to 3.76) and female (pooled OR of 3.00, 95% CI, 2.16 to 4.17). CONCLUSIONS: Our study demonstrated a significantly increased risk of gallstones among HCV-infected patients. Further studies are required to clarify how this risk should be addressed in the clinical picture. PMID- 29193902 TI - Bispecific antibody process development: Assembly and purification of knob and hole bispecific antibodies. AB - Production of knob and hole dual light chain bispecific antibodies poses several unique challenges for development of a feasible industrial scale manufacturing process. We developed an efficient process for the assembly and purification of knob and hole dual light chain bispecific antibodies. Two distinct half antibodies targeting two different antigens were expressed separately in Escherichia coli cells and captured independently using Protein A chromatography. When combined, the knob and hole mutations in the CH3 domains promoted heterodimer formation. The hinge region disulfides were reduced and reoxidized to form the disulfide bridge between the two complementary half antibodies. Unreacted half antibodies, noncovalently linked homodimers, covalently linked homodimers, and noncovalently linked heterodimers are impurities closely related to the product of interest and are challenging to remove by standard processes. Characterization of the molecular properties of the half antibodies and high throughput screening predicted column chromatography performance and allowed for rapid development of downstream purification steps for removal of unique product related and process-related impurities.

PMID- 29193903 TI - Genetic susceptibility to thalidomide embryopathy in humans: Study of candidate development genes. AB - Thalidomide is a drug used worldwide for several indications, but the molecular mechanisms of its teratogenic property are not fully understood. Studies in animal models suggest the oxidative stress, the inhibition of angiogenesis, and the binding to E3-ubiquitin ligase complex as mechanisms by which thalidomide can change the expression of genes important to embryonic development. In this study, seven polymorphisms in genes related to development (FGF8, FGF10, BMP4, SHH, TP53, TP63, and TP73) were analyzed in people with thalidomide embryopathy (TE) and compared to people without malformations. The sample consisted of 36 people with TE and 135 unrelated and nonsyndromic people who had their DNA genotyped by PCR real-time. Although no allelic or genotypic differences were observed between the groups, we hypothesized that other regions in these genes and related genes may play an important role in thalidomide teratogenesis, which is known to have a genetic contribution. Identifying such molecular mechanisms is essential for the development of a molecule that will be analogue to thalidomide but safe enough to avoid the emergence of new cases of TE. PMID- 29193904 TI - Somatic mosaicism of an intragenic FANCB duplication in both fibroblast and peripheral blood cells observed in a Fanconi anemia patient leads to milder phenotype. AB - BACKGROUND: Fanconi anemia (FA) is a rare disorder characterized by congenital malformations, progressive bone marrow failure, and predisposition to cancer. Patients harboring X-linked FANCB pathogenic variants usually present with severe congenital malformations resembling VACTERL syndrome with hydrocephalus. METHODS: We employed the diepoxybutane (DEB) test for FA diagnosis, arrayCGH for detection of duplication, targeted capture and next-gen sequencing for defining the duplication breakpoint, PacBio sequencing of full-length FANCB aberrant transcript, FANCD2 ubiquitination and foci formation assays for the evaluation of FANCB protein function by viral transduction of FANCB-null cells with lentiviral FANCB WT and mutant expression constructs, and droplet digital PCR for quantitation of the duplication in the genomic DNA and cDNA. RESULTS: We describe here an FA-B patient with a mild phenotype. The DEB diagnostic test for FA revealed somatic mosaicism. We identified a 9154 bp intragenic duplication in FANCB, covering the first coding exon 3 and the flanking regions. A four bp homology (GTAG) present at both ends of the breakpoint is consistent with microhomology-mediated duplication mechanism. The duplicated allele gives rise to an aberrant transcript containing exon 3 duplication, predicted to introduce a stop codon in FANCB protein (p.A319*). Duplication levels in the peripheral blood DNA declined from 93% to 7.9% in the span of eleven years. Moreover, the patient fibroblasts have shown 8% of wild-type (WT) allele and his carrier mother showed higher than expected levels of WT allele (79% vs. 50%) in peripheral blood, suggesting that the duplication was highly unstable. CONCLUSION: Unlike sequence point variants, intragenic duplications are difficult to precisely define, accurately quantify, and may be very unstable, challenging the proper diagnosis. The reversion of genomic duplication to the WT allele results in somatic mosaicism and may explain the relatively milder phenotype displayed by the FA-B patient described here. PMID- 29193906 TI - Detection of Sotatercept (ACE-011) in human serum by SAR-PAGE and western single blotting. AB - A method for the detection of Sotatercept (ACE-011, ACVR2A-Fc) in human serum is presented. The method is a modification of a recently published protocol for Luspatercept (ACE-536, ACVR2B-Fc), another erythropoiesis stimulating fusion protein. Out of 27 tested antibodies against either the extracellular domain of ACVR2A or the full-length protein, only 4 antibodies bound strongly enough to Sotatercept for usage with immunoprecipitation followed by SAR-PAGE and Western single blotting. The adapted protocol allows the detection of 0.1 ng/mL Sotatercept in just 50 MUL human serum. None of the 3 commercial ACVR2-ELISAs was able to detect Sotatercept and the 2 tested surrogate proteins, even in the MUg/mL range. As for Luspatercept, only IPG-IEF/2D-PAGE generated discrete isoforms. Due to the long serum half-life, the SAR-PAGE method will be able to detect Sotatercept for several weeks and will be very useful in doping testing. PMID- 29193905 TI - Circulating myomiRs: a new class of biomarkers to monitor skeletal muscle in physiology and medicine. AB - MicroRNAs (miRNA) are small non-coding RNAs that target mRNAs and are consequently involved in the post-transcriptional regulation of gene expression. Some miRNAs are ubiquitously expressed in tissue, while others are tissue specific or tissue-enriched. miRNAs can be released by cells and are found in various biofluids, including serum and plasma. Thus, measuring miRNAs in the circulation may provide information on the originating tissue or cells. MyomiRs are described as striated muscle-specific or muscle-enriched miRNAs. Their circulating levels can be measured and have been proposed to be new biomarkers of physiological and pathological muscle processes. The aims of this review are to summarize the current knowledge of circulating myomiRs, to identify the types of information they can provide about skeletal muscle, and to determine how to apply that information in the fields of research and medicine. PMID- 29193907 TI - Tuberculosis in Pap samples with emphasis on LBC: Caught only when thought. AB - Despite being a commonly encountered infection, the clinical diagnosis of tuberculosis of the uterine cervix is elusive. Though a straightforward diagnosis on tissue sections, identification of typical features of tubercular infection on cervical Pap samples is challenging. In our experience, the infrequent pale staining collections of epithelioid cells are difficult to pick up on Pap stained smears, particularly LBC samples. In this series, 2 of the three samples were reported as atypical squamous cells of undetermined significance while 1 was reported as inflammatory at the initial diagnosis. Scattered Langhans' type giant cells may be seen as a subtle clue which should prompt the search for epithelioid cell granulomas. These cases may have a mass lesion clinically while no obvious signs of malignancy on the cervical samples. PMID- 29193908 TI - A detailed characterization of congenital defects and mortality following moderate X-ray doses during neurulation. AB - BACKGROUND: Both epidemiological and animal studies have previously indicated a link between in utero radiation exposure and birth defects such as microphthalmos, anophthalmos, and exencephaly. However, detailed knowledge on embryonic radiosensitivity during different stages of neurulation is limited, especially in terms of neural tube defect and eye defect development. METHODS: To assess the most radiosensitive stage during neurulation, pregnant C57BL6/J mice were X-irradiated (0.5 Gy or 1.0 Gy) at embryonic days (E)7, E7.5, E8, E8.5, or E9. Next, the fetuses were scored macroscopically for various defects and prenatal resorptions/deaths were counted. In addition, cranial skeletal development was ascertained using the alcian-alizarin method. Furthermore, postnatal/young adult survival was followed until 5 weeks (W5) of age, after X irradiation at E7.5 (0.1 Gy, 0.5 Gy, or 1.0 Gy). In addition, body and brain weights were registered at adult age (W10) following X-ray exposure at E7.5 (0.1 Gy, 0.5 Gy). RESULTS: Several malformations, including microphthalmos and exencephaly, were most evident after irradiation at E7.5, with significance starting respectively at 0.5 Gy and 1.0 Gy. Prenatal mortality and weight were significantly affected in all irradiated groups. Long-term follow-up of E7.5 irradiated animals revealed a reduction in survival at 5 weeks of age after high dose exposure (1.0 Gy), while lower doses (0.5 Gy, 0.1 Gy) did not affect brain and body weight at postnatal week 10. CONCLUSIONS: With this study, we gained more insight in radiosensitivity throughout neurulation, and offered a better defined model to further study radiation-induced malformations and the underlying mechanisms. PMID- 29193909 TI - Controlling Protein Adsorption through Nanostructured Polymeric Surfaces. AB - The initial host response to healthcare materials' surfaces after implantation is the adsorption of proteins from blood and interstitial fluids. This adsorbed protein layer modulates the biological/cellular responses to healthcare materials. This stresses the significance of the surface protein assembly for the biocompatibility and functionality of biomaterials and necessitates a profound fundamental understanding of the capability to control protein-surface interactions. This review, therefore, addresses this by systematically analyzing and discussing strategies to control protein adsorption on polymeric healthcare materials through the introduction of specific surface nanostructures. Relevant proteins, healthcare materials' surface properties, clinical applications of polymer healthcare materials, fabrication methods for nanostructured polymer surfaces, amorphous, semicrystalline and block copolymers are considered with a special emphasis on the topographical control of protein adsorption. The review shows that nanostructured polymer surfaces are powerful tools to control the amount, orientation, and order of adsorbed protein layers. It also shows that the understanding of the biological responses to such ordered protein adsorption is still in its infancy, yet it has immense potential for future healthcare materials. The review, which is-as far as it is known-the first one discussing protein adsorption on nanostructured polymer surfaces, concludes with highlighting important current research questions. PMID- 29193910 TI - Does noninvasive follicular thyroid neoplasm with papillary-like nuclear features have distinctive features on sonography? AB - BACKGROUND: The noninvasive encapsulated follicular variant of papillary carcinoma (nEFVPTC) has recently been reclassified to "noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP)," removing this entity from the malignant category. This re-categorization has had major implications for clinical management. NIFTP has overlapping cytohistologic features with papillary thyroid carcinoma (PTC) and with follicular adenomas (FA), but sonographic data comparing NIFTP to PTC and FA is lacking. Our study examines the sonographic features of NIFTP as compared with PTC and FA. METHODS: Ultrasound scans and Doppler blood flow from subjects who had pre-surgical sonograms and fine needle aspiration biopsies with final surgical pathology diagnoses of NIFTP/nEFVPTC, classical PTC, and FA between 01/2013-08/2016 were assessed. Sonographic and Doppler features as well as Bethesda System (TBS) diagnoses were recorded and analyzed. RESULTS: 40 NIFTP, 58 classical PTC, and 23 FA cases were included. The most common NIFTP pre-surgical TBS cytology diagnosis was Atypia of Undetermined Significance (AUS/FLUS) (40%). NIFTP cases predominantly displayed wider-than-tall shape (100%), smooth borders (75%), occurrence in multinodular glands (82.5%), heterogeneous echogenicity (50%), both perinodular and intranodular Doppler flow patterns (70%), minimal Doppler flow grade (62.5%), and no calcifications (90%). CONCLUSIONS: Our study demonstrates that NIFTP, PTC, and FA display several distinguishing and overlapping sonographic and Doppler features. Sonographic features appear to complement cytology findings and may help raise pre-operative concern for NIFTP in the proper clinical setting, potentially leading to a more conservative management approach. PMID- 29193911 TI - Bacterial Species, Susceptibility to antibiotics and characteristics of patients with surgicalsite infections. AB - Surgical site infections (SSI) are the most common healthcare associatedinfections. Approximately 2-5% of all surgeries develop SSI as a complication.These infections are responsible for significant fatality, morbidity, andlength of hospital stay. The purpose of this study was to describe characteristicsof SSI in a community hospital in Puerto Rico. This was cross sectionalstudy. Between July 2013 and August 2015, 5468 major operativeprocedures were performed and 31 SSI were reported for an overall SSIincidence rate of 0.57%. A total of 31 cases of SSI were studied. The meanage of patients was 59.4 years, with a range of to 29 to 89 years. The medianage was 64 years. The sex distribution showed 22 women (71%) and 9 men(29%). The prevalence rate of diabetes mellitus was 13/31 (42%). In thisstudy 90% of patients with SSI had at least one underlying health condition(diabetes, hypertension, obesity, age > 65 years). Location of surgicalsite infections were: abdominal 16 (52%), orthopedic 4 (13%), pelvic 7(22%), stump 3 (10%), and chest tube 1 (3%). A total of 12 different bacterialpathogens were found. A single etiologic agent was identified in 18 patients(53%) and multiple agents were found in 13 patients (47%). Enterococcusfaecalis was the most common pathogen (45% of patients) followedby Escherichia coli (39% of patients). The majority of bacteria isolated fromcultures were susceptible to B-lactams and aminoglycosides.

AB - Prolactinomas are the most common hormone-secreting pituitary tumorsand represents approximately 40% of all pituitary adenomas. Pharmacologytherapy with dopamine agonists is the mainstay treatment for prolactinomasUsually, patients respond to these drugs with decreased level of the serumprolactin and with time, by tumor shrinkage. Less than 10% of patientswith prolactinomas exhibit resistance to the action of dopamine agonists, asdefined by the lack of normalization of the serum prolactin levels despite long-term treatment at high doses of these drugs. However secondary resistanceto dopamine agonists therapy has also been described in patients who wereinitially responsive to treatment, either with Cabergoline or Bromocriptinebut later develop dopamine agonist resistance, with elevated prolactin levelsand sometimes an enlarging tumor volume several years afterwards.

AB - Dengue is an endemic disease in Puerto Rico, with three to nine thousandsuspected dengue cases reported yearly. In PR, physicians are required to maintainmedical education courses about dengue in order to recertify their medicallicenses. The purpose of this study was to describe characteristics of patientsadmitted to Bella Vista Hospital with suspected dengue and estimate thecompliance with guidelines established by the CDC documented in medical records.A total of 197 medical records of patients admitted with diagnosis of suspecteddengue during January 1, 2013 through December 31, 2013 were reviewed.The annual distribution of admitted cases showed a higher incidenceduring the months of June through September, with August having the higherincidence of all. Combined aches and pains were most commonly reported atadmission with a prevalence of 82%. In general there was a low prevalence ofsevere disease as per definition at presentation (DM, clinical fluid accumulation,hepatomegaly, pregnancy and/or renal insufficiency). Overall, compliancewith CDC established guidelines were only partially followed. The guidelinethat was followed more frequently was a daily CBC, with 95% of patientshaving this as part of their management. Prevalence of administration ofisotonic intravenous fluids was 63%, monitoring of vital signs was 48%),and administration of bolus of intravenous fluid was11%.

AB - OBJECTIVES: The aim of this work is to determine the diabetes treatment satisfactionin a group of hospitalized patients with type 2 diabetes. METHODS: observational cross research. Patients over the age of 18with diagnosed type 2 diabetes of at least one year until the present studywere included. Those presenting pathologies attributed to diabetes wereexcluded. Patients should have responded to the DTSQ questionnaireupon admission. r Pearson regression, multivariate linear regressionand U Mann-Whitney tests were analyzed. RESULTS: A total of 102 patients were included with an average age of 63.1years. Average value of the DTSQs was 14.5.A significant statistic correlation was observed between the score of thequestionnaires and good diabetes control showed by the levels of HbAc1and fasting blood glucose, among other parameters. Indeed there wasno correlation between satisfaction and age and BMI. Women had lowersatisfaction score than men. CONCLUSIONS: levels of diabetes treatment satisfaction in the study populationcorrelated well with diabetic status. That is, the lower diabeticcompromise, the better satisfaction score. The degree of satisfaction inpatients with type 2 diabetes was lower than the observed on patients withthe same pathology but from primary levels of health care.

AB - Methicillin-resistant Staphylococcus aureus (MRSA) is a strain of S. aureus thatshows resistance to multiple antibiotics. Up to 30% of S. aureus strains isolatedfrom nosocomial infections are MRSA, and it has become a growing problemfor public health. The cost of MRSA infection is also having a huge impactfinancially and results in considerable resource utilization. Puerto Rico'sLegislature passed Law # 298 on October 19, 2012 for the control and preventionof MRSA infections in medical installations in Puerto Rico. In order to complywith the law we conducted a pilot study to identify possible setbacks of theimplementation of the MRSA decolonization protocol as standard of care therapy inour institution while contributing to the process of quality improvement andpatient safety. Nasal swabs were taken at the Pre-admission Department andprocessed through a PCR-based MRSA detection assay. A protocol of decolonizationin patients with positive results was implemented. The study showedthat patients without apparent risk factors could be colonized either withMRSA or Methicillin-sensitive S. aureus (MSSA). The time between pre admission and surgery was less than the indicated for a proper decolonizationprocedure. Therefore, 50% of the scheduled surgeries could have beenpostponed in case of positive MRSA or MSSA. In our experience patient's educationwas crucial to guarantee compliance and adherence to treatment. Inorder to decrease risk of wound infection we recommend that both, screeningprocess and decolonization if required, be performed before the preadmissionappointment for elective surgery. This study provided a framework for MRSApre-admission screening and decolonization in our Institution. PMID- 29193923 TI - Intradialytic Hypertension / Hypotension and Mortality in San Juan, Puerto Rico. AB - End Stage Renal Disease patients undergo profound hemodynamic changesduring hemodialysis treatments which are now recognized as a marker forincreased risk of morbidity and mortality. Development of intradialytichypotension or hypertension are a common clinical problem in this populationwith an incidence of up to 20%. We performed a retrospective review of49 Hispanic patients receiving ambulatory hemodialysis during a period of6 months to ascertain the development of aforementioned intradialytic events.Clinical data examined the association of these events to mortality and theirrelationship to antihypertensive medications and cardiomegaly. The prevalenceof intradialytic hypotension was 38.78%, hypertension 16.33% individuallyand both taking place 16.33%. Taken together, the prevalence of theseintradialytic events was 71.43% in our Hispanic population. A significant association was found between mortality and Beta blockers (BB)(P=0.044),Calcium channel blockers (CCB) (P=0.023), cardiomegaly (P=0.044),and intradialytic events (P=0.035). Odds ratio of multiple variables dis-closed that dependent variable death decreased in probability with the useof BB by an estimate of 73% and with the use of CCB by 74.8%. On the otherhand, odds of developing the dependent variable death increased by 74.5% if thepatients developed intradialytic events. Similarly, the odds of developing cardiomegaly in the living group increased by 70%. A logistic regression of multiplevariables found that the probability of developing the dependent condition ofdeath increases by almost 2.896 times if intradialytic events are present andthat there is a 58.9% inferred causality. It is concluded that intradialytic hyper-tension and hypotension are major risk factors for mortality in dialysis patients.The use of BB and CCB may be protetive to avoid the risk of mortality inthese patients.

PMID- 29193925 TI - Klinefelter Syndrome (49, XXXXY/48, XXXY) associated with narrow angle glaucoma:A case report. AB - INTRODUCTION: Previous studies have described Klinefelter syndrome as a geneticdisorder characterized by at least one extra X chromosome and at least 47chromosomes. It is the most common sex chromosome aneuploidy among men.Patients may present with large height, gynecomastia, low testosterone levels,infertility, hypogonadism and diseases usually more common in females suchas osteoporosis, breast cancer and auto-immune disorders. Other rare ophthalmicassociations have been described, such as diffuse choroidal atrophy, microphtalmia,cataracts, juvenile glaucoma, choroid colobomas and goniodysgenesis. OBJECTIVES: To report on the ocular findings in a Puerto Rican patient withKlinefelter syndrome (XXXXY/XXXY). PATIENTS AND METHODS: A patient with Klinefelter syndrome with revious history of elevated intraocularpressure underwent a comprehensive ocular examination, Humphrey visualfields and Stratus optical coherence tomography (OCT) tests. Patient had inreased intraocular pressure, visual field loss and OCT findings compatible withglaucoma. After laser YAG laser iridotomies, high IOP persisted. Brimonidine0.2 % drops three times a day drops were prescribed to lower IOP. CONCLUSIONS: A patient with Klinefelter syndrome had poor visual acuity, high intraocular pressure, visual fields and OCT results, all compatible with angle closureglaucoma as part of the syndrome. PMID- 29193926 TI - Acute Shortening and re-lengthening in the management of open tibia fractures with severe boneof 14 CMS or more and extensive soft tissue loss. AB - INTRODUCTION: A traumatic event to the tibia with more than 14 cm of bone andsoft tissue loss represents a challenge to most orthopedic surgeons and is considered a limb-threatening condition. Few solutions are available in such clinical situations and among them is the acute shortening and re-lengthening ofbone and soft tissue. MATERIALS AND METHODS: Our study presents the management of 7 patientswith grade III B open fractures (according to the Gustillo Andersonclassification) of the tibia who underwent resectionof all the devitalized tissues, acute limb shortening to close the defect,application of an external fixator, and metaphyseal osteotomy for re-lengthening. The patient outcomes were basedon different parameters using the evaluation system established by Paley et al. RESULTS: Results acquired during the study show an average bone loss of 19cm(with a minimum of 14 cm and a maximum of 31.50cm). The average timeto full recovery of all patients was 19 months with a minimum of 14 monthsand a max of 34 months. Patient presented with excellent bony union andnone existent or small refractory leg length discrepancy and did not requirebone grafts or free flaps. Complications that the patients had were contractures,which required secondary procedures such as Achilles tendon re-lengtheningand recurrent infections. DISCUSSION: Overall patients had excellent bone union and were able to perform activities of their daily living. The Ilizarov technique of compression-dis-traction osteogenesis is an elegant treatment option that should be consideredin patients suffering such traumatic events providing excellent bony unionand good functional outcomes for the patient. PMID- 29193927 TI - Pheochromocytoma in pregnancy: A case Report. AB - This is the case of a 38 year-old female patient with an intrauterine pregnancy,in which a previous incidentally identified adrenal mass proved to be apheochromocytoma during the antenatal period. The patient was started onalpha and beta-adrenergic blockade to maintain hemodynamic stability, and surgicalremoval of the lesion was performed during the second trimester without majorcomplications. In view of the rarity of this disorder in pregnancy, it is imperativeto have a high index of suspicion for a prompt and dedicated management,since this tumor, if unrecognized, is associated with high fetal and maternalmortality. PMID- 29193928 TI - Secondary Resistance to dopamine agonist after thirteen months of successful treatment in a 42 years old man. AB - Prolactinomas are the most common hormone-secreting pituitary tumorsand represents approximately 40% of all pituitary adenomas. Pharmacologytherapy with dopamine agonists is the mainstay treatment for prolactinomas.Usually, patients respond to these drugs with decreased level of the serumprolactin and with time, by tumor shrinkage. Less than 10% of patientswith prolactinomas exhibit resistance to the action of dopamine agonists, asdefined by the lack of normalization of the serum prolactin levels despite long-term treatment at high doses of these drugs. However secondary resistanceto dopamine agonists therapy has also been described in patients who wereinitially responsive to treatment, either with Cabergoline or Bromocriptinebut later develop dopamine agonist resistance, with elevated prolactin levelsand sometimes an enlarging tumor volume several years afterwards. Wereport a case of a male patient with prolactinoma who developed drug resistance13 months after initial dopamine agonist therapy. PMID- 29193929 TI - [The evaluation of science].

Mortality in those patients may be as high as 90% mainly due to cardiovascular disease. Despite Framingham score has been validated in the Mexican population, it only predicts cardiovascular risk at 10 years. Meanwhile ASCVD10 score could evaluate risk at 10 years and through lifetime. None of these scores have been used for cardiovascular risk assessment in Mexican patients with severe obesity. METHODS: We conducted a quasi-experimental (before/ after) study with 109 patients with severe obesity, assessed prevalence of comorbidities, performed anthropometric and biochemical evaluations before and a year after bariatric surgery. With these results we calculated Framingham and ASCVD10 scores and compared them. RESULTS: Patients had a mean age of 45.3 +/- 10.1 years, 70% female, 79% underwent laparoscopic Roux-en-Y gastric bypass. We observed weight decrease at each evaluation point after surgery, independently of the surgical procedure. All biochemical parameters improved. Framingham score decreased from 9.4% to 5.9%, frequency of patients classified as high-risk decreased from 25% to 11%. ASCVD10 score decreased from 4.1% to 2.5%, patients classified as high-risk decreased from 28% to 16%. Tobacco use was the most important factor involved in cardiovascular risk. CONCLUSIONS: Cardiovascular risk at 10-years and lifetime decreased as soon as one year after surgery as assessed through Framingham and ASCVD scores.

AB - BACKGROUND: The aim of this paper is to compare the efficacy of tamsulosin, oxybutynin or their combination for the treatment of symptoms related to double J stent (DJS). METHODS: Randomized clinical non-blinded trial with three arms (tamsulosin, oxybutynin or combination) to assess the improvement of ureteral related symptoms with DJS with the questionnaire of Ureteral Stent Symptom Questionnaire (USSQ) and the adverse effects of treatment. Evaluations were made at 7 and 21 days after the placement of DJS. The maneuvers were compared using Chi squared test, Kruskall-Wallis, ANOVA and Wilcoxon considering a statistically significant p <= 0.05. RESULTS: 170 patients with CJJ were evaluated. A perprotocol analysis was performed in 142 patients, 53 received tamsulosin (37.4%), 42 oxybutynin (29.6%) and 47 the combination of both (33%). At 7 and 21 days the improvement was similar in all three arms. Men with tamsulosin and women with oxybutynin had less general symptoms. CONCLUSIONS: Tamsulosin, oxybutynin or its combination similarly improve ureteral stent related symptoms and this improvement becomes more noticeable over time. Men are less symptomatic with tamsulosin and women with oxybutynin. PMID- 29193938 TI - [Knowledge, behavior and perception of oral health in patients with type 2 diabetes]. AB - BACKGROUND: Periodontal disease occurs severely in patients with diabetes, also causes high blood glucose. The objective of this article was to determine knowledge, behavior and perception of oral health in patients with type 2 diabetes. METHODS: Cross-sectional study performed at the Unidad de Medicina Familiar No. 26 in Acapulco, Guerrero, Mexico; 376 patients with type 2 diabetes were included. Sociodemographic questionnaire, knowledge, behavior and perception of oral health was applied. RESULTS: 21% was sent to the dental service by the family doctor. 86% of the patients performed dental brushing 2-3 times a day; 57% perceived the relationship diabetes and oral health. In signs of oral disease they predominated with 34% gingival bleeding and inflammation with 30%. Main reason was for emergency dental surgery. CONCLUSIONS: The patient suffering from diabetes does not recognize the dentist as the main character in the comprehensive healthcare; on the other hand, the family doctor does not send a prevention stomatology. It is necessary to develop educational strategies focused on the family doctor and patient in terms of importance of oral health. PMID- 29193939 TI - [Prevalence of subclinical hypothyroidism in pediatric patients with drug resistant epilepsy]. AB - BACKGROUND: In several studies it has been reported a high prevalence of subclinical hypothyroidism in children with epilepsy secondary to the use of monotherapy with valproic acid, carbamazepine and phenytoin. The aim of this article is to determine the prevalence of subclinical hypothyroidism in children with drug-resistant epilepsy treated at the Pediatric Neurology Service of the Hospital de Pediatria, Centro Medico Nacional Siglo XXI in Mexico City. METHODS: We conducted a descriptive cross-sectional study. All pediatric patients with drug-resistant epilepsy and without structural alteration seen at the pediatric neurology service of our hospital between January 1 and June 1 2015 were included. Results: Prevalence of subclinical hypothyroidism in our sample was of 25%, with most patients receiving polytherapy with valproic acid. CONCLUSIONS: The intentional searching for subclinical hypothyroidism in pediatric patients with drug-resistant epilepsy without structural alteration might be considered as part of routine medical care and patients receiving combination therapy with valproic acid they should be considered as a subgroup with an increased risk of developing such comorbidity.

(Mch), popularly known as chamomile, has been used for centuries as an herbolary remedy due to its broad clinical spectrum. The aim of this study was to evaluate the effect of Mch associated to a vehicle with emollient function in induced atopic dermatitis (AD)-like lesions in a murine model. METHODS: AD was induced with dinitrochlorobenzene on 12 male seven-week old BALB/c mice. Animals were divided in three groups (control, GC; control negative, GCN; and experimental, GE). Liquid petrolatum was applied to the GCN and liquid petrolatum with aqueous extract of Mch at 7% to the GE. Induction and evolution of the lesions were verified by biopsy at 2nd and 6th week. Evaluation of peripheral blood cells to correlate inflammatory cells was made as well at the same weeks. Lesions were clinically evaluated at 2nd, 4th and 6th week. Scratching was monitored according to the observation methodology of Kobayashi et al. RESULTS: Mch aqueous extract associated to a vehicle with emollient function improves atopic dermatitis-like lesions after two weeks.

AB - BACKGROUND: International literature reports a prevalence of 50% of thyroid nodules detected during autopsies of subjects without known thyroid disease. Currently there are no studies of this type in Mexico. The aim was to identify the prevalence of thyroid nodules in autopsied bodies without known thyroid pathology. METHODS: A series of cases of 300 cadavers without known thyroid pathology, from which we obtained their thyroid glands. It was analyzed the presence of thyroid nodules as well as their macroscopic and microscopic characteristics. RESULTS: 300 autopsies were included. 123 cadavers (41%) presented thyroid nodules; 69 were men (56%) and 54, women (44%). The mean age was 37 +/- 14 years. A total of 149 nodules were found, out of which 94 were solid nodules (63%), and 55 were cystic (37%). Histopathological diagnosis of malignancy was found in 12 of the analyzed thyroid glands (4%). CONCLUSIONS: There was a greater prevalence of thyroid nodules in men and in subjects whose age at the time of dying was 45 years or less, unlike what is found in the international literature. We consider necessary to create screening programs for early diagnosis of thyroid nodules.

AB - Microsurgery is one of the most fertile and innovative area in reconstructive surgery. Today it is considered an indispensable technique in plastic surgery with flaps survival rates over 95% in main healthcare centers. The factors involved in achieving these results are: the improvement of the surgical technique, adequate patient selection and careful perioperative care. Perioperative care starts at the initial assessment of the patient where it's very important to consider the indications and contraindications of these procedures. We use this type of reconstruction when we face complex and extensive defects, they are mostly of the times, difficult or impossible to reconstruct with other techniques. Antibiotic prophylaxis should begin an hour before initial incision. Free flap procedures are classified as maximum risk for venous thromboembolism so it's essential to indicate an appropriate prophylaxis. Normothermia, proper fluid management and judicious use of transfusions and vasopressor are a fundamental part of intraoperative care. Postoperative monitoring of these flaps is essential for early detection of vascular thrombosis in order to save the transferred tissue.

AB - BACKGROUND: The most common cause of injury is shoulder impingement syndrome. Management includes physical therapy, analgesics, steroids and surgery. The aim of the study was to determine the cost-effectiveness of using steroids combined with therapeutic exercise at home in the chronic impingement syndrome. METHODS: Clinical trial randomized in 30 people with subacromial impingement syndrome underwent two treatments: steroid and at home rehabilitation booklet evaluated at the first and fourth week through UCLA Shoulder rating scale. RESULTS: We studied 17 men (56.7 %) and 13 women (43.3 %), mean age was 42.87 years. Group 2 earned greater improvement in UCLA Shoulder rating scale 18.87 at baseline and 27.60 at the end. With 30.27 accumulated disability days for group 1, and 14.80 for group 2. CONCLUSIONS: The combination of local steroids with therapeutic exercise is more effective clinically and declining disability compared to conventional physical therapy.

AB - The Williams-Beuren (SWB; OMIM 194050) syndrome is an autosomal dominant multisystem disorder that occurs in ~ 1 in 20,000 live births and results from a 7q11.23 deletion spanning ~ 28 genes. This deletion is caused by a nonallelic homologous recombination (NAHR) between low copy repeats present therein. The SWB phenotype is characterized by neonatal hypercalcemia, mental disability, distinctive personality and cognitive profile, short stature, dysmorphic facies, connective tissue disorders and supravalvular aortic stenosis. Ninety percent of the deletions are of 1.5 Mb, 8% of 1.84Mb, and only 2% are atypical. Although only ~ 40 atypical deletions have been described, they have contributed to clarify the genotype-phenotype correlation and allowed for a more integrative management. In this review we highlight the importance of detecting atypical deletions in patients with SWB. PMID- 29193945 TI - [The pulmonary hypertension of the chronic kidney disease]. AB - Pulmonary hypertension in chronic kidney disease is included in the group 5 of the pulmonary hypertension classification of the World Health Organization. Its mechanism is multifactorial and little known.

PMID- 29193947 TI - [Tuberculosis caused by Mycobacterium bovis, a re-emerging infection?] AB - Currently, tuberculosis (TB) is a public health problem, is present in all regions of the world and remains one of the most deadly communicable diseases, particularly associated with infection by the human immunodeficiency virus (HIV). Cases of TB Mycobacterium bovis more and more frequent, especially in vulnerable populations. TB caused by M. bovis clinical, radiological and histologically indistinguishable from tuberculosis caused by M. tuberculosis; however, there are some differences that make M. tuberculosis particular. The direct correlation between infection with M. bovis in cattle and human disease has been well documented, but the true prevalence is underestimated. Overall, the proportion of cases of human TB caused by M. bovis is low compared with M. tuberculosis, but its potential in the groups most at risk impact should not be underestimated by the impact on morbidity and mortality. PMID- 29193948 TI - [Bayesian tragedy, from clinical iatrogenesis to biotechnology]. AB - Diagnostic algorithms, as well as the biotechnological design, require the calculation of conditional probability, given the presence of certain positive data, in the context of prevalence, sensitivity and specificity; It is necessary to estimate the probability that the patient has a certain disease. Sometimes, with a test of scrutiny, it goes from a probability of 1/1000 to 1/20, constituting a great diagnostic advance, reducing the uncertainty spectacularly; However, the tragedy is that most doctors believe that the probability changed from 0.1% (1/1000) to more than 90%, which is outrageously wrong. Iatrogeny arises from the error in answering the question: "given that the test is positive, what is the probability that the patient has the disease?" In other cases, tragedy is to apply a test to an individual belonging to a subpopulation for which it was not designed. In addition, it is evident that the fascination for the sensitivity avoids the application of less sensitive methods in populations that are abandoned; It is not a matter of making better tests than those that the State does to the patients it attends, but of making less accurate tests for the patients that the State does not attend.

AB - BACKGROUND: Clostridium difficile is a spore-forming bacterium, producing exotoxins, causing potentially fatal nosocomial diarrhea. They have recently reported outbreaks of C. difficile ribotype 027, which is characterized by a hypervirulent strain and high resistance to standard therapy. CLINICAL CASE: We present three cases of Clostridium difficile NAP1/027/BI associated infection, they were presented with different clinical manifestations. Two of the patients were successfully treated with the combination of vancomycin plus tigecycline. The other case was treated with fecal microbiota transplant, with resolution of the disease. CONCLUSION: in patients with Clostridium difficile NAP1/027/BI associated infection is a good therapeutic option to consider the use of tigecycline in conjunction with vancomycin, as well as fecal microbiota transplantation.

There are two clinical types: unicentric and multicentric with three histological variants, hyaline-vascular, plasma celular and mixed. The most common sites of this are mediastinum, adbomen and neck. Magnetic resonance imaging is well suited to depict the characteristics of the masses and their relationship to adjacent structures. The knowledge of this disease and its inclusion in the differential diagnosis from other neck masses will contribute to the therapeutic approach. CLINICAL CASE: A 21 years old female patient with a left neck mass characterized by magnetic resonance as solid, heterogeneous, vascularized lesion, pre dominantly isointensa on T1-weighted images an high signal on T2-weighted images and fat sat that demonstrate moderate enhancement after contraste material administration located in posterior space of the neck with extension at thoracic outlet displacing structures of carotid, anterior cervical and viceral spaces. She underwent complete surgical resection of the mass with histopathological diagnosis of hyaline-vascular type of Castleman's disease. CONCLUSION: Magnetic resonance is well suited to depict characteristic and the extent of mass in the neck contributing to narrow the differential diagnosis. Imaging findings, especially of magnetic resonance are very important to choose the treatment of Castleman's disease.

AB - In this study, highly transparent conducting fluorine-doped tin oxide (FTO) electrodes were fabricated using the horizontal ultrasonic spray pyrolysis deposition. In order to improve their transparent conducting performances, we carried out oxygen activation by adjusting the ratio of O2/(O2+N2) in the carrier gas (0%, 20%, and 50%) used during the deposition process. The oxygen activation on the FTO electrodes accelerated the substitution concentration of F (FO*) into the oxygen sites in the FTO electrode while the oxygen vacancy (VO**) concentration was reduced. In addition, due to growth of pyramid-shaped crystallites with (200) preferred orientations, this oxygen activation caused the formation of a uniform surface structure. As a result, compared to others, the FTO electrode prepared at 50% O2 showed excellent electrical and optical properties (sheet resistance of ~4.0 +/- 0.14 Omega/?, optical transmittance of ~85.3%, and figure of merit of ~5.09 +/- 0.19 * 10-2 Omega-1). This led to a superb photoconversion efficiency (~7.03 +/- 0.20%) as a result of the improved short-circuit current density. The photovoltaic performance improvement can be defined by the decreased sheet resistance of FTO used as a transparent conducting electrode in dye-sensitized solar cells (DSSCs), which is due to the combined effect of the high carrier concentration by the improved FO* concentration on the FTO electrodes and the fasted Hall mobility by the formation of a uniform FTO surface structure and distortion relaxation on the FTO lattices resulting from the reduced VO*** concentration. PMID- 29193955 TI - Polymeric Nanoparticle-Coated Pickering Emulsion-Synthesized Conducting Polyaniline Hybrid Particles and Their Electrorheological Study. AB - To produce an electric stimuli-responsive electrorheological (ER) material, semiconducting core/shell-type polyaniline (PANI) hybrid particles were fabricated through Pickering emulsion-type polymerization, using poly(divinylbenzene-alt-maleic anhydride) (PDVMA) particles as a solid surfactant. The PDVMA nanoparticles were initially polymerized using a self stable precipitation method. The fabricated PANI/PDVMA composite particles were subjected to various chemical characterizations; further, they were suspended in silicone oil at 10 vol % to prepare an ER fluid, and their viscoelastic behaviors were scrutinized using a rheometer under various input electric fields. We also adopted an LCR meter to evaluate its dielectric characteristics. Our results showed that the PANI/PDVMA composite particles display typical ER performance, such that both dynamic and elastic yield stresses follow a polarization mechanism with a slope of 2.0. PMID- 29193956 TI - Native-MS Analysis of Monoclonal Antibody Conjugates by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry. AB - Antibody-drug conjugates (ADCs) are an important class of therapeutic molecule currently being used to treat HER2-positive metastatic breast cancer, relapsed or refractory Hodgkin lymphoma, systemic anaplastic large cell lymphoma, relapsed or refractory B-cell precursor acute lymphoblastic leukemia, and acute myeloid leukemia. An ADC typically consists of a small molecule or peptide-based cytotoxic moiety covalently linked, via lysine or cysteine residues, to a monoclonal antibody (mAb) scaffold. Mass spectrometric (MS) characterization of these molecules affords highly accurate molecular weight (MW) and drug-to antibody ratio (DAR) determination and is typically performed using orthogonal acceleration time-of-flight (oa-ToF) analyzers and more recently, Orbitrap instruments. Herein we describe for the first time the use of a 15 T solariX Fourier transform ion cyclotron mass spectrometer to characterize an IgG1 mAb molecule conjugated with biotin via native lysine and cysteine residues, under native-MS and solution conditions. The cysteine-biotin conjugates remained fully intact, demonstrating the ability of the FT-ICR to maintain the noncovalent interactions and efficiently transmit labile protein complexes. Native-MS was acquired and is displayed in magnitude mode using a symmetric Hann apodization function. Baseline separation is achieved on all covalent biotin additions, for each charge state, for both the lysine- and cysteine-biotin conjugates. Average DAR values obtained by native-MS for the lysine conjugate are compared to those derived by denaturing reversed phase liquid chromatography using an oa-ToF MS system (1.56 +/- 0.02 versus 2.24 +/- 0.02 for the 5 equivalent and 3.99 +/- 0.09 versus 4.43 +/- 0.01 for the 10 equivalent, respectively). Increased DAR value accuracy can be obtained for the higher biotin-load when using standard ESI conditions as opposed to nanoESI native-MS conditions. PMID- 29193957 TI - Functional Characterization of Insulation Effect for Synthetic Gene Circuits in Mammalian Cells. AB - Insulators are noncoding gene regulatory elements in eukaryotic genome, which function as chromatin partitioning boundaries, and block interference across different chromatin domains. To facilitate modular construction of synthetic gene circuit that is usually composed of multiple transcription cassettes, unwanted cross-regulations between different cassettes should be avoided. Here, we developed a quantitative method to characterize the functional effect of three insulators on the cross-regulations of six promoters in mammalian cells. We showed that the unwanted cross-regulations displayed a threshold-like effect, and the threshold position varied along with the context of promoters and insulators. We tested the function of insulators in both cascade and sensory switch circuits assembled in episomal plasmid vectors, and showed that the insulation effect was mainly revealed on the first regulatory layer of the cascade circuit. A deviation on the response curve of the sensory switch circuit with or without insulators was observed, but response intensity of some sensory switch circuits were not affected. Therefore, our results provided a general guide on the selection of insulators with varying promoters in episomal synthetic gene circuits in mammalian cells, which may be useful to reduce the effect of the unwanted cross regulations. PMID- 29193958 TI - Crosstalk between Diverse Synthetic Protein Degradation Tags in Escherichia coli. AB - Recently, a synthetic circuit in E. coli demonstrated that two proteins engineered with LAA tags targeted to the native protease ClpXP are susceptible to crosstalk due to competition for degradation between proteins. To understand proteolytic crosstalk beyond the single protease regime, we investigated in E. coli a set of synthetic circuits designed to probe the dynamics of existing and novel degradation tags fused to fluorescent proteins. These circuits were tested using both microplate reader and single-cell assays. We first quantified the degradation rates of each tag in isolation. We then tested if there was crosstalk between two distinguishable fluorescent proteins engineered with identical or different degradation tags. We demonstrated that proteolytic crosstalk was indeed not limited to the LAA degradation tag, but was also apparent between other diverse tags, supporting the complexity of the E. coli protein degradation system.

Taking the cheap and stable hematite (alpha-Fe2O3) wormlike nanostructure photoanode as a model system, we design a facile sacrificial interlayer approach to suppress the crystal overgrowth and realize Ti doping into the crystal lattice of alpha-Fe2O3 in one annealing step as well as to avoid the consequent anodic shift of the photocurrent onset potential, ultimately achieving five times increase in its water oxidation photocurrent compared to the bare hematite by promoting the transport of charge carriers, including both separation of photogenerated charge carriers within the bulk semiconductor and transfer of holes across the semiconductor-electrolyte interface. Our research indicates that understanding the semiconductor/electrolyte interfacial engineering mechanism is pivotal for reconciling various strategies in a beneficial way, and this simple and cost effective method can be generalized into other systems aiming for efficient and scalable solar energy conversion. PMID- 29193960 TI - Continuous and High-Throughput Electromechanical Lysis of Bacterial Pathogens Using Ion Concentration Polarization. AB - Electrical lysis of mammalian cells has been a preferred method in microfluidic platforms because of its simple implementation and rapid recovery of lysates without additional reagents. However, bacterial lysis typically requires at least a 10-fold higher electric field (~10 kV/cm), resulting in various technical difficulties. Here, we present a novel, low-field-enabled electromechanical lysis mechanism of bacterial cells using electroconvective vortices near ion selective materials. The vortex-assisted lysis only requires a field strength of ~100 V/cm, yet it efficiently recovers proteins and nucleic acids from a variety of pathogenic bacteria and operates in a continuous and ultrahigh-throughput (>1 mL/min) manner. Therefore, we believe that the electromechanical lysis will not only facilitate microfluidic bacterial sensing and analysis but also various high volume applications such as the energy-efficient recovery of valuable metabolites in biorefinery pharmaceutical industries and the disinfection of large-volume fluid for the water and food industries. PMID- 29193961 TI - Chemical Proteomics Reveals Soluble Epoxide Hydrolase as a Therapeutic Target for Ocular Neovascularization. AB - The standard-of-care therapeutics for the treatment of ocular neovascular diseases like wet age-related macular degeneration (AMD) are biologics targeting vascular endothelial growth factor signaling. There are currently no FDA approved small molecules for treating these blinding eye diseases. Therefore, therapeutic agents with novel mechanisms are critical to complement or combine with existing approaches. Here, we identified soluble epoxide hydrolase (sEH), a key enzyme for epoxy fatty acid metabolism, as a target of an antiangiogenic homoisoflavonoid, SH-11037. SH-11037 inhibits sEH in vitro and in vivo and docks to the substrate binding cleft in the sEH hydrolase domain. sEH levels and activity are up regulated in the eyes of a choroidal neovascularization (CNV) mouse model. sEH is overexpressed in human wet AMD eyes, suggesting that sEH is relevant to neovascularization. Known sEH inhibitors delivered intraocularly suppressed CNV. Thus, by dissecting a bioactive compound's mechanism, we identified a new chemotype for sEH inhibition and characterized sEH as a target for blocking the CNV that underlies wet AMD. PMID- 29193962 TI - Cell Penetrating Polymers Containing Guanidinium Trigger Apoptosis in Human Hepatocellular Carcinoma Cells unless Conjugated to a Targeting N-Acetyl Galactosamine Block. AB - A series of 3-guanidinopropyl methacrylamide (GPMA)-based polymeric gene delivery vehicles were developed via aqueous reversible addition-fragmentation chain transfer (RAFT) polymerization. The polymers have been evaluated for their cellular internalization ability, transfection efficiency, and cytotoxicity. Two homopolymers: P(GPMA20), P(GPMA34), were synthesized to study the effect of guanidium polymer length on delivery efficiency and toxicity. In addition, an N acetyl-d-galactosamine (GalNAc)-based hydrophilic block was incorporated to produce diblock polymers, which provides a neutral hydrophilic block that sterically protects plasmid-polymer complexes (polyplexes) from colloidal aggregation and aids polyplex targeting to hepatocytes via binding to asialoglycoprotein receptors (ASGPRs). Polyplexes formed with P(GPMAx) (x = 20, 34) homopolymers were shown to be internalized via both energy-dependent and independent pathways, whereas polyplexes formed with block polymers were internalized through endocytosis. Notably, P(GPMAx) polyplexes enter cells very efficiently but are also very toxic to human hepatocellular carcinoma (HepG2) cells and triggered cell apoptosis. In comparison, the presence of a carbohydrate block in the polymer structures reduced the cytotoxicity of the polyplex formulations and increased gene delivery efficiency with HepG2 cells. Transfection efficiency and toxicity studies were also carried out with HEK 293T (human embryonic kidney) cells for comparison. Results showed that polyplexes formed with the P(GPMAx) homopolymers exhibit much higher transfection efficiency and lower toxicity with HEK 293T cells. The presence of the carbohydrate block did not further increase transfection efficiency in comparison to the homopolymers with HEK 293T cells, likely due to the lack of ASGPRs on the HEK 293T cell line. This study revealed that although guanidinium-based polymers have high membrane permeability, their application as plasmid delivery vehicles may be limited by their high cytotoxicity to certain cell types. Thus, the use of cell penetrating structures in polyplex formulations should be used with caution and carefully tailored toward individual cell/tissue types.

AB - Metal-free, formal [2 + 2 + 2] cycloaddition strategies for the synthesis of polycyclic pyridine derivatives are described. The overall transformation proceeds via a two-stage pericyclic cascade mechanism. In the first step, an intramolecular propargylic ene reaction generates a vinylallene that is necessarily locked in the s-cis conformation. This vinylallene exhibits exceptional reactivity as a Diels-Alder reaction partner and engages in [4 + 2] cycloadditions with normally unreactive azadienophiles including unactivated cyano groups and heterosubstituted imine derivatives such as dimethylhydrazones and oximino ethers. Few examples of oximino ether Diels-Alder reactions have been reported previously, and normal electron-demand [4 + 2] cycloadditions of unactivated dialkylhydrazones are unprecedented. Overall, this metal-free formal [2 + 2 + 2] cycloaddition provides access to polycyclic pyridine derivatives and complements transition-metal-catalyzed [2 + 2 + 2] strategies. PMID- 29193964 TI - Out-of-Equilibrium Aggregates and Coatings during Seeded Growth of Metallic Nanoparticles. AB - Although dissipative self-assembly is ubiquitous in nature, where it gives rise to structures and functions critical to life, examples of artificial systems featuring this mode of self-assembly are rare. Here, we identify the presence of ephemeral assemblies during seeded growth of gold nanoparticles. In this process, hydrazine reduces Au(III) ions, which attach to the existing nanoparticles "seeds". The attachment is accompanied by a local increase in the concentration of a surfactant, which therefore forms a bilayer on nanoparticle surfaces, inducing their assembly. The resulting aggregates gradually disassemble as the surfactant concentration throughout the solution equilibrates. The lifetimes of the out-of-equilibrium aggregates depend on and can be controlled by the size of the constituent nanoparticles. We demonstrate the utility of our out-of equilibrium aggregates to form transient reflective coatings on polar surfaces.

PMID- 29193965 TI - Stability and Water Accessibility of the Trimeric Membrane Anchors of the HIV-1 Envelope Spikes. AB - HIV-1 envelope spike (Env) is a type I membrane protein that mediates viral entry. Recent studies showed that its transmembrane domain (TMD) forms a trimer in lipid bilayer whose structure has several peculiar features that remain difficult to explain. One is the presence of an arginine R696 in the middle of the TM helix. Additionally, the N- and C-terminal halves of the TM helix form trimeric cores of opposite nature (hydrophobic and hydrophilic, respectively). Here we determined the membrane partition and solvent accessibility of the TMD in bicelles that mimic a lipid bilayer. Solvent paramagnetic relaxation enhancement analysis showed that the R696 is indeed positioned close to the center of the bilayer, but, surprisingly, can exchange rapidly with water as indicated by hydrogen-deuterium exchange measurements. The solvent accessibility of R696 is likely mediated by the hydrophilic core, which also showed fast water exchange. In contrast, the N-terminal hydrophobic core showed extremely slow solvent exchange, suggesting the trimer formed by this region is extraordinarily stable. Our data explain how R696 is accommodated in the middle of the membrane while reporting the overall stability of the Env TMD trimer in lipid bilayer. PMID- 29193967 TI - Structure-Guided Discovery of Novel, Potent, and Orally Bioavailable Inhibitors of Lipoprotein-Associated Phospholipase A2. AB - Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a promising therapeutic target for atherosclerosis, Alzheimer's disease, and diabetic macular edema. Here we report the identification of novel sulfonamide scaffold Lp-PLA2 inhibitors derived from a relatively weak fragment. Similarity searching on this fragment followed by molecular docking leads to the discovery of a micromolar inhibitor with a 300-fold potency improvement. Subsequently, by the application of a structure-guided design strategy, a successful hit-to-lead optimization was achieved and a number of Lp-PLA2 inhibitors with single-digit nanomolar potency were obtained. After preliminary evaluation of the properties of drug-likeness in vitro and in vivo, compound 37 stands out from this congeneric series of inhibitors for good inhibitory activity and favorable oral bioavailability in male Sprague-Dawley rats, providing a quality candidate for further development. The present study thus clearly demonstrates the power and advantage of integrally employing fragment screening, crystal structures determination, virtual screening, and medicinal chemistry in an efficient lead discovery project, providing a good example for structure-based drug design. PMID- 29193968 TI - Structural Insight into the Photochemistry of Split Green Fluorescent Proteins: A Unique Role for a His-Tag. AB - Oligohistidine affinity tags (His-tags) are commonly fused to proteins to aid in their purification via metal affinity chromatography. These His-tags are generally assumed to have minimal impact on the properties of the fusion protein, as they have no propensity to form ordered elements, and are small enough not to significantly affect the solubility or size. Here we report structures of two variants of truncated green fluorescent protein (GFP), i.e., split GFP with a beta-strand removed, that were found to behave differently in the presence of light. In these structures, the N-terminal His-tag and several neighboring residues play a highly unusual structural and functional role in stabilizing the truncated GFP by substituting as a surrogate beta-strand in the groove vacated by the native strand. This finding provides an explanation for the seemingly very different peptide binding and photodissociation properties of split proteins involving beta-strands 10 and 11. We show that these truncated GFPs can bind other non-native sequences, and this promiscuity invites the possibility for rational design of sequences optimized for strand binding and photodissociation, both useful for optogenetic applications.

One trimeric compound was also isolated and one porphyrin dimer linked by palladium(II) could be structurally characterized. In solution, the size of the new compounds was estimated by DOSY NMR techniques. These compounds all contained long aliphatic chains (O-C12H25), which were used to assemble them at a highly oriented pyrolytic graphite (HOPG)/liquid interface. The highly ordered arrays were visualized by scanning tunneling microscopy (STM). PMID- 29193971 TI - On-the-Fly Computation of Frontal Orbitals in Density Matrix Expansions. AB - We propose a method for computation of frontal (homo and lumo) orbitals in recursive polynomial expansion algorithms for the density matrix. Such algorithms give a computational cost that increases only linearly with system size for sufficiently sparse systems, but a drawback compared to the traditional diagonalization approach is that molecular orbitals are not readily available. Our method is based on the idea to use the polynomial of the density matrix expansion as an eigenvalue filter giving large separation between eigenvalues around homo and lumo [ Rubensson et al. J. Chem. Phys. 2008 , 128 , 176101 ]. This filter is combined with a shift-and-square (folded spectrum) method to move the desired eigenvalue to the end of the spectrum. In this work we propose a transparent way to select recursive expansion iteration and shift for the eigenvector computation that results in a sharp eigenvalue filter. The filter is obtained as a byproduct of the density matrix expansion, and there is no significant additional cost associated either with its construction or with its application. This gives a clear-cut and efficient eigenvalue solver that can be used to compute homo and lumo orbitals with sufficient accuracy in a small fraction of the total recursive expansion time. Our algorithms make use of recent homo and lumo eigenvalue estimates that can be obtained at negligible cost [ Rubensson et al. SIAM J. Sci. Comput . 2014 , 36 , B147 ]. We illustrate our method by performing self-consistent field calculations for large scale systems. PMID- 29193972 TI - Properties of Single-Walled Aluminosilicate Nanotube/Poly(vinyl alcohol) Aqueous Dispersions. AB - The properties of (synthesized) single-walled aluminosilicate nanotube (AlSiNT; light-scattering characterized length ~2000 +/- 230 nm and diameter ~35 +/- 4 nm) dispersed in an aqueous poly(vinyl alcohol) (PVA) solution (10 wt %) are systematically explored using a comprehensive combination of (polarized/depolarized) dynamic light scattering, rheological, rheo-optical, and scanning electron microscopy analysis schemes. The nanotube/polymer dispersions under investigation are promising for their fair nanotube dispersion in pristine aqueous media (e.g., without salt or acid addition), as well as for the optical transparency that greatly facilitates systematic exploration of structural features and dispersion state that are practically inaccessible for many of their (opaque) companions such as carbon nanotube dispersions. We provide the first in depth analysis revealing excellent dispersion state of (unmodified) AlSiNT in the PVA matrix, giving rise to (critical) gel-like features and substantially promoted elasticity that can be utilized, as a practical assessment, to produce uniform and defect-free electrospun nanofibers. Additionally, there is unambiguous evidence of nematic liquid crystal-like "wagging" (strain-invariant, periodic oscillation) under steady shear flow, a phenomenon previously unreported for nanotube composite materials. Overall, the present findings suggest that AlSiNT/PVA dispersions possess promising rheological, optical, and electrospinning properties that are highly desirable for current nanotechnological applications, and may serve as an ideal model system for establishing structure-performance relationships for like nanotube/polymer composite materials. PMID- 29193970 TI - Predicted Biological Activity of Purchasable Chemical Space. AB - Whereas 400 million distinct compounds are now purchasable within the span of a few weeks, the biological activities of most are unknown. To facilitate access to new chemistry for biology, we have combined the Similarity Ensemble Approach (SEA) with the maximum Tanimoto similarity to the nearest bioactive to predict activity for every commercially available molecule in ZINC. This method, which we label SEA+TC, outperforms both SEA and a naive-Bayesian classifier via predictive performance on a 5-fold cross-validation of ChEMBL's bioactivity data set (version 21). Using this method, predictions for over 40% of compounds (>160 million) have either high significance (pSEA >= 40), high similarity (ECFP4MaxTc >= 0.4), or both, for one or more of 1382 targets well described by ligands in the literature. Using a further 1347 less-well-described targets, we predict activities for an additional 11 million compounds. To gauge whether these predictions are sensible, we investigate 75 predictions for 50 drugs lacking a binding affinity annotation in ChEMBL. The 535 million predictions for over 171 million compounds at 2629 targets are linked to purchasing information and evidence to support each prediction and are freely available via https://zinc15.docking.org and https://files.docking.org .

Our in situ electron microscopy observations and atomistic simulations demonstrate that the (2 * 1) reconstruction of the Cu3Au(110) surface alloy remains as a stable surface structure as a result of the favored Cu-Au diatom configuration. PMID- 29193975 TI - Aqueous Lubrication, Structure and Rheological Properties of Whey Protein Microgel Particles. AB - Aqueous lubrication has emerged as an active research area in recent years due to its prevalence in nature in biotribological contacts and its enormous technological soft-matter applications. In this study, we designed aqueous dispersions of biocompatible whey-protein microgel particles (WPM) (10-80 vol %) cross-linked via disulfide bonding and focused on understanding their rheological, structural and biotribological properties (smooth polydimethylsiloxane (PDMS) contacts, Ra < 50 nm, ball-on-disk set up). The WPM particles (Dh = 380 nm) displayed shear-thinning behavior and good lubricating performance in the plateau boundary as well as the mixed lubrication regimes. The WPM particles facilitated lubrication between bare hydrophobic PDMS surfaces (water contact angle 108 degrees ), leading to a 10-fold reduction in boundary friction force with increased volume fraction (phi >= 65%), largely attributed to the close packing-mediated layer of particles between the asperity contacts acting as "true surface-separators", hydrophobic moieties of WPM binding to the nonpolar surfaces, and particles employing a rolling mechanism analogous to "ball bearings", the latter supported by negligible change in size and microstructure of the WPM particles after tribology. An ultralow boundary friction coefficient, MU <= 0.03 was achieved using WPM between O2 plasma-treated hydrophilic PDMS contacts coated with bovine submaxillary mucin (water contact angle 47 degrees ), and electron micrographs revealed that the WPM particles spread effectively as a layer of particles even at low phi~ 10%, forming a lubricating load-bearing film that prevented the two surfaces from true adhesive contact. However, above an optimum volume fraction, MU increased in HL+BSM surfaces due to the interpenetration of particles that possibly impeded effective rolling, explaining the slight increase in friction. These effects are reflected in the highly shear thinning nature of the WPM dispersions themselves plus the tendency for the apparent viscosity to fall as dispersions are forced to very high volume fractions. The present work demonstrates a novel approach for providing ultralow friction in soft polymeric surfaces using proteinaceous microgel particles that satisfy both load bearing and kinematic requirements. These findings hold great potential for designing biocompatible particles for aqueous lubrication in numerous soft matter applications.

AB - Chirped-pulse Fourier transform millimeter-wave spectroscopy is a potentially powerful tool for studying chemical reaction dynamics and kinetics. Branching ratios of multiple reaction products and intermediates can be measured with unprecedented chemical specificity; molecular isomers, conformers, and vibrational states have distinct rotational spectra. Here we demonstrate chirped pulse spectroscopy of vinyl cyanide photoproducts in a flow tube reactor at ambient temperature of 295 K and pressures of 1-10 MUbar. This in situ and time resolved experiment illustrates the utility of this novel approach to investigating chemical reaction dynamics and kinetics. Following 193 nm photodissociation of CH2CHCN, we observe rotational relaxation of energized HCN, HNC, and HCCCN photoproducts with 10 MUs time resolution and sample the vibrational population distribution of HCCCN. The experimental branching ratio HCN/HCCCN is compared with a model based on RRKM theory using high-level ab initio calculations, which were in turn validated by comparisons to Active Thermochemical Tables enthalpies.

AB - In the quest for new, efficient, and noble-metal-free H2-evolution catalysts, hydrogenase enzymes are a source of inspiration. Here, we describe the development of a new hybrid material based on a structural and functional [NiFe] hydrogenase model complex (NiFe) incorporated into the Zr-based MOF PCN-777. The bulk NiFe@PCN-777 material was synthesized by simple encapsulation. Characterization by solid-state NMR and IR spectroscopy, SEM-EDX, ICP-OES, and gas adsorption confirmed the inclusion of the guest. FTO-supported thin films of the NiFe@PCN-777 composite were obtained by electrophoretic deposition of the bulk material and characterized by SEM-EDX, ICP-OES, and cyclic voltammetry. The average surface concentration of electroactive NiFe catalyst in the film was found to be ~9.6 * 10-10 mol cm-2, implying that a surprisingly high fraction (37%) of NiFe units incorporated in the MOF are electroactive. By cyclic voltammetry, we showed that NiFe maintains its electrocatalytic capabilities for H+ reduction inside the MOF cavities, even if under controlled-potential electrolysis conditions the activity of NiFe cannot be discerned from that of free PCN-777 and FTO. PMID- 29193980 TI - A Randomized, Multicenter, Double-Blind, Study to Evaluate the Safety and Efficacy of Estradiol Vaginal Cream 0.003% in Postmenopausal Women with Vaginal Dryness as the Most Bothersome Symptom. AB - BACKGROUND: Vulvovaginal atrophy (VVA) is characterized by vaginal/vulvar dryness, irritation, dyspareunia, or dysuria. The objective of this study was to examine the efficacy and safety of a very low-dose estradiol vaginal cream (0.003%) applied twice per week in postmenopausal women with VVA-related vaginal dryness. MATERIALS AND METHODS: In this phase 3, randomized, double-blind, placebo-controlled, multicenter study, postmenopausal women with moderate-severe vaginal dryness as the most bothersome VVA symptom were randomized (1:1) to estradiol cream 0.003% (15 MUg estradiol; 0.5 g cream) or placebo (0.5 g cream). Treatments were applied vaginally once daily for 2 weeks followed by two applications/week for 10 weeks. Coprimary outcomes were changes in severity of vaginal dryness, percentage of vaginal superficial and parabasal cells, and vaginal pH at final assessment. Additional outcomes comprised changes in severity of other VVA signs and symptoms. Adverse events (AEs) were assessed. RESULTS: Of the 576 randomized participants, most were white and had an average age of 59 years. At final assessment, estradiol reduced vaginal dryness severity, decreased vaginal pH, increased superficial cell percentage, and decreased parabasal cell percentage versus placebo (p <= 0.05, all). Estradiol also reduced vaginal dryness severity at Weeks 4-12 and dyspareunia at Week 8 versus placebo (p <= 0.05, all). Improvements in vaginal/vulvar irritation/itching severity and dysuria were similar between estradiol and placebo. Estradiol had comparable rates of treatment-emergent AEs to placebo. No deaths occurred. CONCLUSIONS: Very low-dose estradiol vaginal cream (0.003%) dosed twice weekly is an effective and well-tolerated treatment for VVA symptoms and dryness associated with menopause. PMID- 29193979 TI - When Enough Is Enough: Decision Criteria for Moving a Known Drug into Clinical Testing for a New Indication in the Absence of Preclinical Efficacy Data. AB - Many animal models of disease are suboptimal in their representation of human diseases and lack of predictive power in the success of pivotal human trials. In the context of repurposing drugs with known human safety, it is sometimes appropriate to conduct the "last experiment first," that is, progressing directly to human investigations. However, there are not accepted criteria for when to proceed straight to humans to test a new indication. We propose a specific set of criteria to guide the decision-making around when to initiate human proof of principle without preclinical efficacy studies in animal models. This approach could accelerate the transition of novel therapeutic approaches to human applications. PMID- 29193981 TI - The Relationship between Structure-Related Food Parenting Practices and Children's Heightened Levels of Self-Regulation in Eating. AB - BACKGROUND: Food parenting practices influence children's eating behaviors and weight status. Food parenting practices also influence children's self-regulatory abilities around eating, which has important implications for children's eating behaviors. The purpose of the following study is to examine use of structure related food parenting practices and the potential impact on children's ability to self-regulate energy intake. METHODS: Parents (n = 379) of preschool age children (M = 4.10 years, SD = 0.92) were mostly mothers (68.6%), Non-White (54.5%), and overweight/obese (50.1%). Hierarchical Multiple Regression was conducted to predict child self-regulation in eating from structure-related food parenting practices (structured meal setting, structured meal timing, family meal setting), while accounting for child weight status, parent age, gender, BMI, race, and yearly income. RESULTS: Hierarchical Multiple Regression results indicated that structure-related feeding practices (structured meal setting and family meal setting, but not structured meal timing) are associated with children's heightened levels of self-regulation in eating. Models examining the relationship within children who were normal weight and overweight/obese indicated the following: a relationship between structured meal setting and heightened self-regulation in eating for normal-weight children and a relationship between family meal setting and heightened self-regulation in eating for overweight/obese children. CONCLUSIONS: Researchers should further investigate these potentially modifiable parent feeding behaviors as a protective parenting technique, which possibly contributes to a healthy weight development by enhancing self-regulation in eating. PMID- 29193983 TI - Characterization of Departures from Regulatory Requirements Identified During Inspections Conducted by the US Federal Select Agent Program, 2014-15. AB - We studied departures from regulatory requirements identified on US Federal Select Agent Program (FSAP) inspections to increase transparency regarding biosafety and security risk at FSAP-regulated entities and identify areas for programmatic improvement. Regulatory departures from inspections led by Centers for Disease Control and Prevention inspectors during 2014-15 were grouped into "biosafety," "security," and "other" observation categories and assigned a risk level and score reflecting perceived severity. The resulting 2,267 biosafety (n = 1,153) and security (n = 1,114) observations from 296 inspections were analyzed by frequency and risk across entity and inspection characteristics. The greatest proportion of biosafety observations involved equipment and facilities (28%), and the greatest proportion of security observations involved access restrictions (33%). The greatest proportion of higher-risk observations for biosafety were containment issues and for security were inventory discrepancies. Commercial entities had the highest median cumulative risk score per inspection (17), followed by private (13), academic (10), federal government (10), and nonfederal government (8). Maximum containment (BSL-4) inspections had higher median biosafety risk per inspection (13) than other inspections (5) and lower security risk (0 vs 4). Unannounced inspections had proportionally more upper risk level observations than announced (biosafety, 21% vs 12%; security, 18% vs 7%). Possessors of select agents had higher median biosafety risk per inspection (6) than nonpossessors (4) and more upper risk level security observations (10% vs 0%). Programmatic changes to balance resources according to entity risk may strengthen FSAP oversight. Varying inspection methods by select agent possession and entity type, and conducting more unannounced inspections, may be beneficial.

AB - Purpose The 21-gene assay Oncotype Dx (Genomic Health, Redwood City, CA) test is used to aid the decision about chemotherapy in patients with hormone receptor positive breast cancer who received endocrine therapy. Economic studies to support test adoption used decision-analytic models with assumptions and data derived from disparate sources. The objective was to evaluate whether the 21-gene assay test resulted in an overall cost expense or saving to the health system. Patients and Methods One thousand participants enrolled in a field evaluation study, were linked to population-level health system administrative databases, and were observed for 20 months. The cost for the cohort, which included the cost of the test, subsequent treatments received, and health care encounters, was determined. The cost in the absence of the test was compared with the pretest recommendation about chemotherapy from the field study for a base case and under scenarios that reflected different adjuvant chemotherapy use. Overall health system costs and incremental costs were calculated. Results The 21-gene assay resulted in a net decrease in chemotherapy use of 23%. For the base case incremental analysis, the actual overall health system cost of this cohort, including the cost of 21-gene assay, was $29.2 million compared with $26.2 million in the absence of the test-an increase of $3.1 million. For three of the four scenario analyses, the actual overall cost to the health system exceeded the estimated cost in the absence of the test. Results showed that, when at least half of the population received adjuvant chemotherapy, the cost increased to $30.2 million. Conclusion The use of real-world administrative data showed that, despite lower rates of chemotherapy use, the 21-gene assay test results in an overall incremental cost to the health care system in the short-term under most assumptions.

AB - With the threat of future radiological or nuclear events, there is a need to model and develop new medical countermeasures for managing large-scale population exposures to radiation. The field of radiation biodosimetry has advanced far beyond its original objectives to identify new methodologies to quantitate unknown levels of radiation exposure that may be applied in a mass screening setting. New research in the areas of genomics, proteomics, metabolomics, transcriptomics, and electron paramagnetic resonance (EPR) applications have identified novel biological indicators of radiation injury from a diverse array of biological sample materials, and studies continue to develop more advanced models of radiation exposure and injury. In this article, we identify the urgent need for new biodosimetry assessment technologies, describe how biodosimetry diagnostics work in the context of a broad range of radiation exposure types and scenarios, review the current state of the science, and assess how well integrated biodosimetry resources are in the national radiological emergency response framework.

AB - PURPOSE: This study was conducted to find differences between patients with schizophrenia and healthy control group in ToM and to examine relationships among intelligence, ToM, and delusion in patients with schizophrenia. METHODS: Data was collected from 50 patients of schizophrenia and 32 healthy subjects. Participants were given the psychological test form with structured questionnaire. The SPSS 22.0 program was used for t-test, ANCOVA, and, Pearson's Correlation. Measurements used for this study were Korean-Wechsler intelligence scale, three types of Theory of Mind test (Hinting task, False belief task, and Emotional attribution test), and Peters delusion inventory. RESULTS: Performances of the ToM and intelligence in patients were lower than healthy controls. After controlling the impact of IQ, education level, and age, there was a difference between patients and healthy controls on the performance of the Hinting task (F(1,83) = 10.03, p =.002). Correlation analysis showed that the score of false belief task was correlated with delusion (r = -.360, p <.01) and intelligence (r =.449, p <.01). The emotional attribution task was correlated with intelligence (r = 0.309, p <.05). CONCLUSIONS: Through the finding of this study, theory of mind is highly recommended as a new target factor considering to develop nursing interventions for schizophrenia.

After DP, we established two experiments comparing single vs. repetitive DP (S-DP and R-DP, respectively) until passage 2 (P2) completion. Each experiment included a set of cultures consisting of 5 floating-to-attached cell ratios (5, 10, 15, 20, and 25) and control cultures containing floating cells only. We found similar cell and colony count drops during P0 in both S- and R-DP. During P2, counts increased in S-DP in middle ratios (10, 15, and especially 20) relative to low and high ratios (5 and 25, respectively). Counts dropped extensively in R-DP after passage 2. The superiority of intermediate ratios was demonstrated by enrichment of GFRalpha1 by qPCR. The optimal ratio of 20 in S-DP contained significantly increased proportions of GFRalpha1-positive cells (25.8+/-5.8%) as measured by flow cytometry compared to after DP (1.9+/-0.7%, p<0.0001), as well as positive immunostaining for GFRalpha1 and UTF1, with rare Sox9-positive cells. This is the first report of the impact of initial floating-to-attached cell ratios on SSC proliferation in vitro.

AB - Diplopia is a disappointing and, at times, unanticipated consequence of what might otherwise be considered anatomically successful strabismus surgery. In this study, we review the existing literature regarding diplopia after strabismus surgery in the context of the senior author's experience. We divide postoperative diplopia types into cases that occur in the setting of normal binocular vision (or "normal" suppression) vs. cases that are the consequence of rare or anomalous sensorial adaptations. We then discuss how to identify patients at greatest risk based on history and preoperative testing, and we offer strategies for managing these sometimes-challenging cases. PMID- 29193992 TI - TLRs/NLRs: Shaping the landscape of host immunity. AB - Innate immune system provides the first line of defense against pathogenic organisms. It has a varied and large collection of molecules known as pattern recognition receptors (PRRs) which can tackle the pathogens promptly and effectively. Toll-like receptors (TLRs) and NOD-like receptors (NLRs) are members of the PRR family that recognize pathogen associated molecular patterns (PAMPs) and play pivotal roles to mediate defense against infections from bacteria, fungi, virus and various other pathogens. In this review, we discuss the critical roles of TLRs and NLRs in the regulation of host immune-effector functions such as cytokine production, phagosome-lysosome fusion, inflammasome activation, autophagy, antigen presentation, and B and T cell immune responses that are known to be essential for mounting a protective immune response against the pathogens. This review may be helpful to design TLRs/NLRs based immunotherapeutics to control various infections and pathophysiological disorders. PMID- 29193993 TI - Effects of Anthropometric Variables and Seat Height on Automobile Drivers' Preferred Posture With the Presence of the Clutch. AB - Objective The effects of seat height and anthropometric dimensions on drivers' preferred postures were investigated using a multiadjustable vehicle mock-up with a large number of adjustments and extended ranges. Background Many studies have been conducted on preferred driving posture under different test conditions showing mixed and even contradictory findings. No studies thus far have considered the clutch and compared Chinese and European drivers. Method Four seat height conditions were tested: free and three imposed heights (250, 300, and 350 mm). Sixty-one subjects (40 French-born and 21 Chinese-born) participated in the experiment, covering a large range of stature and sitting height-to-stature ratio. The RAMSIS kinematic model was used to reconstruct postures, and main intersegmental angles were extracted for characterizing posture. Results Under the free seat height condition, no significant differences in preferred intersegmental angles were observed between different participant groups. Seat height mainly affected trunk-thigh angle, whereas it had almost no effect on trunk orientation and other intersegmental angles. Chinese participants sat more forward in the seat, leading to a more opened trunk-thigh angle and a more reclined trunk. Conclusions Results suggest that intersegmental angles of preferred posture are not dependent on anthropometric dimensions, although shorter drivers prefer a slightly less reclined trunk. Self-selected driving posture results from a compromise between maintaining the intersegmental angles in one's preferred range and a preferred trunk orientation in space. Applications The findings contribute to a better understanding of preferred driving postures and would be helpful for improving vehicle interior design.

AB - Objective The study's objective was to assess a new personnel selection and assessment tool for aviation security screeners. A mobile app was modified to create a tool, and the question was whether it could predict professional screeners' on-job performance. Background A variety of professions (airport security, radiology, the military, etc.) rely on visual search performance-being able to detect targets. Given the importance of such professions, it is necessary to maximize performance, and one means to do so is to select individuals who excel at visual search. A critical question is whether it is possible to predict search competency within a professional search environment. Method Professional searchers from the USA Transportation Security Administration (TSA) completed a rapid assessment on a tablet-based X-ray simulator (XRAY Screener, derived from the mobile technology app Airport Scanner; Kedlin Company). The assessment contained 72 trials that were simulated X-ray images of bags. Participants searched for prohibited items and tapped on them with their finger. Results Performance on the assessment significantly related to on-job performance measures for the TSA officers such that those who were better XRAY Screener performers were both more accurate and faster at the actual airport checkpoint. Conclusion XRAY Screener successfully predicted on-job performance for professional aviation security officers. While questions remain about the underlying cognitive mechanisms, this quick assessment was found to significantly predict on-job success for a task that relies on visual search performance. Application It may be possible to quickly assess an individual's visual search competency, which could help organizations select new hires and assess their current workforce. PMID- 29193996 TI - Genome-wide association study of rice grain width variation. AB - Seed size is variable within many plant species, and understanding the underlying genetic factors can provide insights into mechanisms of local environmental adaptation. Here we make use of the abundant genomic and germplasm resources available for rice (Oryza sativa) to perform a large-scale genome-wide association study (GWAS) of grain width. Grain width varies widely within the crop and is also known to show climate-associated variation across populations of its wild progenitor. Using a filtered dataset of >1.9 million genome-wide SNPs in a sample of 570 cultivated and wild rice accessions, we performed GWAS with two complementary models, GLM and MLM. The models yielded 10 and 33 significant associations, respectively, and jointly yielded seven candidate locus regions, two of which have been previously identified. Analyses of nucleotide diversity and haplotype distributions at these loci revealed signatures of selection and patterns consistent with adaptive introgression of grain width alleles across rice variety groups. The results provide a 50% increase in the total number of rice grain width loci mapped to date and support a polygenic model whereby grain width is shaped by gene-by-environment interactions. These loci can potentially serve as candidates for studies of adaptive seed size variation in wild grass species. PMID- 29193998 TI - Relation Among Anxiety and Family Burden in Primary First-Degree Caregivers of Outpatients with Mental Disorders in Turkey. AB - The aim of this study was to determine the relation among anxiety and family burden in primary first-degree relative caregivers of outpatients with mental disorders in Turkey. Data were collected with patients' primary first-degree relative caregivers via the Information Form, Beck Anxiety Inventory (BAI), and Perceived Family Burden Scale (PFBS). In all, 481 caregivers (325 women and 156 men) participated in this study. Based on this study's results, primary caregivers of patients with mental disorders had a moderate level anxiety, and as anxiety increased, family burden also increased. Those results suggest that mental health nurses should plan interventions not only for patients, but also for their family member or their caregivers to decrease anxiety level. PMID- 29193995 TI - Beck Depression Inventory-II: Factor Analyses with Three Groups of Midlife Women of African Descent in the Midwest, the South, and the U.S. Virgin Islands. AB - This research encompasses a factor analysis of the Beck Depression Inventory-II (BDI-II), which involves three groups of midlife women of African descent who reside in the Midwest, the South, and the U.S. Virgin Islands. The purpose of the study was to determine the factor structure of the BDI-II when administered to a sample of women aged 40-65 of African descent who reside in the three distinct geographical regions of the United States. A correlational, descriptive design was used, and 536 women of African descent were invited to participate in face-to face interviews that transpired in community settings. Results of the factor analysis revealed a two-factor explanation. Factor one included symptoms such as punishment feelings and pessimism (cognitive), and the second factor included symptoms such as tiredness and loss of energy (somatic-affective). The application of the Beck Depression Inventory-II among the three groups of women generated specific information about each group and common findings across the groups. Knowledge gained from the research could help to guide specific intervention programs for the three groups of women, and explicate the common approaches that could be used for the three groups. PMID- 29193999 TI - Nursing and the Emergence of Egoless Care: A Discussion on Social Engineering in Mental Health. AB - The narrowing of the diverse fields of psychiatry to just the single dimension of the biomedical model has resulted in a situation where professions with a focus on curing (psychiatrists and psychologists) are favoured over those with a focus on caring and encouraging near communities to care for each other (nurses). The social engineering of mental problems leads to a state of helplessness. This paper contributes to an understanding of the barriers to utilise the social resources of people with mental health problems and argues for forms of "indirect social engineering" and "egoless care," and, ultimately, a rediscovery of nursing, using the mental health care in the Netherlands as a case study. PMID- 29194000 TI - Time dependent reduction in platelet aggregation using the multiplate analyser and hirudin blood due to platelet clumping. AB - The Multiplate is a popular instrument that measures platelet function using whole blood. Potentially considered a point of care instrument, it is also used by hemostasis laboratories. The instrument is usually utilized to assess antiplatelet medication or as a screen of platelet function. According to the manufacturer, testing should be performed within 0.5-3 hours of blood collection, and preferably using manufacturer provided hirudin tubes. We report time associated reduction in platelet aggregation using the Multiplate and hirudin blood collection tubes, for all the major employed agonists. Blood for Multiplate analysis was collected into manufacturer supplied hirudin tubes, and 21 consecutive samples assessed using manufacturer supplied agonists (ADP, arachidonic acid, TRAP, collagen and ristocetin), at several time-points post sample collection within the recommended test time period. Blood was also collected into EDTA as a reference method for platelet counts, with samples collected into sodium citrate and hirudin used for comparative counts. All platelet agonists showed a diminution of response with time. Depending on the agonist, the reduction caused 5-20% and 22-47% of responses initially in the normal reference range to fall below the reference range at 120min and 180min, respectively. Considering any agonist, 35% and 67% of initially "normal" responses became 'abnormal' at 120 min and 180 min, respectively. Platelet counts showed generally minimal changes in EDTA blood, but were markedly reduced over time in both citrate and hirudin blood, with up to 40% and 60% reduction, respectively, at 240 min. The presence of platelet clumping (micro-aggregate formation) was also observed in a time dependent manner, especially for hirudin. In conclusion, considering any platelet agonist, around two-thirds of samples can, within the recommended 0.5-3 hour testing window post-blood collection, yield a reduction in platelet aggregation that may lead to a change in interpretation (i.e., normal to reduced). Thus, the stability of Multiplate testing can more realistically be considered as being between 30-120 min of blood collection for samples collected into hirudin. PMID- 29194002 TI - Auranofin, a thioredoxin reductase inhibitor, causes platelet death through calcium overload. AB - Platelets are central to normal hemostasis and must be tightly controlled to prevent thrombosis. However, drug treatments that also affect platelets could lead to unwanted side effects on hemostasis or thrombosis. In this study, the effect of auranofin on platelets was tested. Auranofin, a gold-based thioredoxin reductase (TRXR) inhibitor, has been previously used in arthritis. Recently, auranofin and other inhibitors of the thioredoxin system have been proposed as novel anti-cancer therapies. TRXR is an important part of the antioxidant defenses in many cells that maintain intracellular proteins in their reduced state. TRXR activity in platelets could be completely inhibited by auranofin. Auranofin-treated platelets showed several features of cell death, including the inability to aggregate in response to thrombin, leakage of cytosolic lactate dehydrogenase, and surface exposure of procoagulant phosphatidylserine. Auranofin increased platelet reactive oxygen species production and intracellular calcium concentration. DTT, a sulfydyl reducing agent, and BAPTA-AM, which chelates intracellular calcium, prevented auranofin-induced phosphatidylserine exposure. These data suggest that TRXR is an important part of the platelet antioxidant defense. TRXR inhibition by auranofin triggers oxidative stress and disrupts intracellular calcium homeostasis, leading to platelet necrosis. The use of auranofin or other TRXR inhibitors could therefore lead to unwanted side effects. PMID- 29194001 TI - Racial Disparities in Clinically Significant Prostate Cancer Treatment: The Potential Health Information Technology Offers. AB - PURPOSE: Black men are more likely to die as a result of prostate cancer than white men, despite effective treatments that improve survival for clinically significant prostate cancer. We undertook this study to identify gaps in prostate cancer care quality, racial disparities in care, and underlying reasons for poorer quality care. METHODS: We identified all black men and random age-matched white men with Gleason scores >= 7 diagnosed between 2006 and 2013 at two urban hospitals to determine rates of treatment underuse. Underuse was defined as not receiving primary surgery, cryotherapy, or radiotherapy. We then interviewed treating physicians about the reasons for underuse. RESULTS: Of 359 black and 282 white men, only 25 (4%) experienced treatment underuse, and 23 (92%) of these were black. Most (78%) cases of underuse were due to system failures, where treatment was recommended but not received; 38% of these men continued receiving care at the hospitals. All men with treatment underuse due to system failures were black. CONCLUSION: Treatment rates of prostate cancer are high. Yet, racial disparities in rates and causes of underuse remain. Only black men experienced system failures, a type of underuse amenable to health information technology based solutions. Institutions are missing opportunities to use their health information technology capabilities to reduce disparities in cancer care. PMID- 29194003 TI - Mediating effect of deviant peers on the relationship between sensation seeking and lifetime smoking among high school students. AB - BACKGROUND: Despite the greater risk of lifetime smoking among high sensation seekers, it is difficult to change a sensation seeking tendency through interventions. Therefore, it is important to identify a modifiable factor mediating the link between these two conditions in order to weaken or disconnect the association. OBJECTIVES: Based on the literature, deviant peers may play a pivotal role in explaining this association. Thus, we aimed to investigate the mediating effect of deviant peers on the association between sensation seeking and lifetime smoking among Korean adolescents. METHODS: We analyzed secondary data obtained from 876 high school students. Approximately 51% of the participants were male. In order to investigate the mediating effect of deviant peers after controlling for 16 factors, we tested an indirect effect in a simple mediation model using the PROCESS macro, which is a regression-based approach. RESULTS: We found a significant total effect of sensation seeking on lifetime smoking: greater risk of lifetime smoking among high sensation seekers. In addition, we found a significant mediating effect of deviant peers on the association between the two conditions. Specifically, higher sensation seeking successfully predicted a greater number of deviant peers, which, in turn, successfully predicted greater risk of lifetime smoking. CONCLUSION: Given difficulties in directly changing levels of sensation seeking and the significant mediating effect of deviant peers on the association between the two conditions, prevention strategies focusing on peers may be advantageous for high sensation seekers in reducing their risk of lifetime smoking in adolescence.

PMID- 29194005 TI - Patient Characteristics, Length of Stay, and Functional Improvement for Schizophrenia Spectrum Disorders: A Population Study of Inpatient Care in Ontario 2005 to 2015. AB - OBJECTIVES: Schizophrenia and associated illnesses account for a large proportion of mental illness burden and health care expenditures, with the majority of expense involving inpatient care. To date, the literature exploring factors associated with length of stay (LOS) and functional improvement during inpatient care is underdeveloped. In response, this study examined the association between patient characteristics, LOS, and functional improvement using Ontario Mental Health Reporting System (OMHRS) data from 2005 to 2015. METHODS: The associations of patient characteristics (including key demographics, psychosocial variables, reasons for admission, and service use history) and 2 outcome measures (LOS and Global Assessment of Functioning [GAF]) were analysed with generalised linear mixed modelling (GLMM). From 2005 to 2015, a total of 48,498 episodes for distinct patients from 18 psychiatric hospitals and 57 general hospitals in Ontario were included. RESULTS: For psychiatric and general hospitals, mean LOS was 96.6 and 20.5 days, and mean GAF improvement was 14.8 and 16.1, respectively. The majority of associations probed demonstrated a high degree of significance with similar patterns across general and tertiary facility contexts. Older age and more recent readmission following a psychiatric discharge were associated with longer LOS and less GAF improvement. Recent experience of adverse life events and substance misuse were associated with shorter LOS. CONCLUSIONS: While the findings of this exploratory cross-sectional analysis will require further inquiry with respect to validity and reliability, they suggest that a different service pathway is likely required for individuals with greater psychosocial challenge and extensive service use histories. PMID- 29194006 TI - Retention of functional characteristics of glutathione-S-transferase and lactate dehydrogenase-A in fusion protein. AB - A paradigm shift toward fusion proteins to render multiple functionalities and applications on a single platform has been incurred in enzyme based diagnosis. Herein, we report development and systematic characterizations of glutathione-S transferase (GST) and human lactate dehydrogenase A (hLDHA) in a fusion protein (GST-hLDHA) to achieve functional activities of GST and hLDHA simultaneously. The GST-pGEX-4T-2 vector system was used for cloning and purification of hLDHA, utilizing the affinity based interaction between GST and GSH in column chromatography. Bacterially purified protein was subjected to the Western blot analysis and structural analysis by circular dichroism spectroscopy, which revealed intact structural framework of the fusion construct. Kinetic characterization of the fusion GST-hLDHA protein toward GSH and NADH, suggested retention of functional activities of GST and hLDHA in fused protein as indicated by the kinetic parameters km and kcat/km. Further analysis of effect of temperature and pH on GST-hLDHA activity revealed maximum activity around human physiological conditions (37 degrees C and pH 8). Preservation of the structural and functional characteristics of the fusion enzyme paves the way for potential application for the detection of NADH and GSH in conjunction as biomarkers for cancer diagnosis. PMID- 29194007 TI - Product review on the Anti-PD-L1 antibody atezolizumab. AB - Immunotherapy as a therapeutic strategy has seized the narrative throughout clinical oncology over the past few years. Once considered a niche treatment for rare cancers, immunotherapy has quickly emerged as the standard of care for many common cancer types. The remarkable rise is largely due to the development of novel checkpoint inhibitors, specifically, antibodies targeting PD-1 and PD-L1. Offering promising efficacy with a favorable toxicity profile, these agents have been approved for use in several malignancies and are under investigation for many more. One of the more appealing features is the chance for meaningful, durable response - uncharacteristic for most cancer therapies. Atezolizumab is a humanized IgG1 monoclonal antibody that targets PD-L1. Atezolizumab has been approved for use in the treatment of advanced non-small cell lung cancer (NSCLC) and bladder cancer and has shown promising activity in several other types of cancer. Here, we provide a product review for atezolizumab. PMID- 29194008 TI - Removal of excess nutrients by Australian zeolite during anaerobic digestion of swine manure. AB - The objective of this study was to investigate the feasibility of using natural and NaCl-treated Australian zeolites to simultaneously remove excess nutrients from anaerobically digested swine manure. Ion adsorption and desorption properties of Australian zeolite during the anaerobic digestion of swine manure were investigated. Two experiments were conducted: the first was an adsorption experiment with multi-component solutions that corresponded with the ionic composition of swine manure digestates. The second experiment determined the effects of zeolite dose rates during anaerobic digestion of swine manure on the removal of N, P and K from solution. Adsorption isotherms confirmed selectivity for K+ over NH4+ by Australian natural and sodium zeolites. Therefore, NH4+ removal was considerably reduced when there was simultaneous K+ uptake. Natural zeolite desorbed more Ca2+ during K+ and NH4+ adsorption than sodium zeolite. The ion exchange reaction was independent of the presence of P. P removal was very dependent on the pH of the medium. Natural Australian zeolite was shown to be a potential sorbent for the removal of NH4+, K+ and P during the anaerobic digestion of swine manure. However, the application of high concentrations of zeolite at higher pH values (> 7.5) might not be appropriate for anaerobic digestion, because zeolite desorbed more Ca2+ ions into the solution at the higher doses of zeolite and then availability of P for microbial growth might be reduced as a result of PO43- precipitation with Ca2+ at the higher pH. PMID- 29194009 TI - Bias in Radiology: The How and Why of Misses and Misinterpretations. AB - Medical errors are a leading cause of morbidity and mortality in the medical field and are substantial contributors to medical costs. Radiologists play an integral role in the diagnosis and care of patients and, given that those in this field interpret millions of examinations annually, may therefore contribute to diagnostic errors. Errors can be categorized as a "miss" when a primary or critical finding is not observed or as a "misinterpretation" when errors in interpretation lead to an incorrect diagnosis. In this article, the authors describe the cognitive causes of such errors in diagnostic medicine, specifically in radiology. Recognizing the cognitive processes that radiologists use while interpreting images should improve one's awareness of the inherent biases that can impact decision making. The authors review the common biases that impact clinical decisions, as well as strategies to counteract or minimize the potential for misdiagnosis. System-level processes that can be implemented to minimize cognitive errors are reviewed, as well as ways to implement personal changes to minimize cognitive errors in daily practice. (c)RSNA, 2017. PMID- 29194010 TI - Impact of serogroup A meningococcal conjugate vaccine for Africa. AB - The introduction of a serogroup A meningococcal conjugate vaccine in the African meningitis belt has been a remarkable success. Meningitis due to the serogroup A meningococcus, previously responsible for most epidemics, has fallen by 99% in vaccinated countries. Success must, however, not distract from the continuing burden of meningitis in this region of Africa. The number of all meningitis epidemics at health district level has fallen by 60% following vaccination, but epidemics due to other meningococcal serogroups continue and may be increasing. The introduction of low cost multivalent conjugate vaccines must be given high public health priority. PMID- 29194011 TI - Rapid Source-Control Laparotomy: Is There a Mortality Benefit in Septic Shock? AB - BACKGROUND: In the 1990s, damage control laparotomy (DCL) became a proved approach to treat intra-abdominal injuries caused by trauma. In the ensuing two decades, this approach has been applied to non-traumatic abdominal processes as well. Although the benefits of DCL are clear, the benefit of rapid source-control laparotomy (RSCL) for non-traumatic abdominal diseases is much less clear. However, two recent cohort analyses identified significant increases in the mortality rate with RCSL compared with primary fascial closure (PFC). The purpose of this study was to assess the efficacy of RSCL in patients with septic shock. METHODS: The 2015 National Surgical Quality Improvement Project (NSQIP) database was queried for 11 International Statistical Classifications of Diseases (ICD)-10 codes associated with septic shock. Collected data included age, gender, body mass index (BMI), wound class, American Society of Anesthesiologists (ASA) class, operative time, number of risk factors, and presence or absence of post-operative pneumonia. The risk factors were diabetes mellitus, alcohol or tobacco abuse, blood dyscrasias, disseminated cancer, and cardiac, gastrointestinal, pulmonary, hepatobiliary, or renal dysfunction. The primary outcomes were rate of re operation, prevalence of post-operative pneumonia, hospital length of stay (LOS), and death by 30 days. RESULTS: The RSCL and PFC cohorts were each comprised of 56 patients matched for propensity scores for ICD-10 code. There were no significant differences in wound or ASA class, BMI, gender, or number of risk factors between the two cohorts. The operative time for RSCL was significantly shorter than for PFC (median 84 vs. 128 min, respectively; p = 0.002). There was no significant difference in re-operation rate, prevalence of post-operative pneumonia, LOS, or mortality rate between the two cohorts. CONCLUSIONS: Although this analysis showed no clear advantage to RSCL in the management of septic shock, it may be a means to salvage certain patients. The best way to assess the relative value of RSCL is a prospective trial. PMID- 29194012 TI - Funding vaccines for emerging infectious diseases. AB - Immunization has played a large role in substantially reducing the infected and death tolls from infectious diseases. In the case of emerging diseases, the identity of the pathogen responsible, as well as the time and location for the next outbreak, cannot be accurately predicted using current means. Coupled with disjointed efforts towards the development of vaccines and a lack of funds and desire to advance promising products against known emerging pathogens to clinical trials, there has been a shortage of approved products ready for emergency use. Recent outbreaks have exposed these weaknesses, and the Coalition for Epidemic Preparedness Innovations (CEPI) was created in 2016 to address these issues. In this commentary, we discuss the establishment of such a global vaccine fund, and provide some additional points to consider for stimulating further discussion on this comprehensive, ambitious initiative. PMID- 29194013 TI - Public policy for meningococcal vaccination. AB - On an individual basis, meningococcal disease is consistently shown to be one of the most feared potential childhood infections. On a population level, any clustering of cases or increase in disease requires proactive health protection management, while epidemics can be devastating. It is therefore no surprise that developing protective meningococcal vaccines and effective strategies for their implementation has been a continuing public health priority for some decades. PMID- 29194014 TI - Respiratory syncytial virus seasonality and its implications on prevention strategies. AB - With maternal and infant vaccines against respiratory syncytial virus (RSV) in development, it is timely to consider how the deployment of these vaccines might vary according to local RSV disease seasonality. In temperate regions RSV infection is predictably limited to a period of 3 to 5 months, while in tropical regions disease seasonality is often both more variable and more prolonged. Accordingly, in tropical regions a year-round immunisation schedule for both maternal and infant immunisation might be appropriate. In contrast, in temperate regions the benefit of year-round maternal immunisation would be heavily dependent on the duration of protection this provided, potentially necessitating a strategy directed at children due to be born in the months immediately prior to the RSV season. This review will consider the impact of seasonality on maternal and infant immunisation strategies against RSV, and the potential of an alternative approach of passive immunisation for all infants immediately prior to the RSV season. PMID- 29194015 TI - Phytase from Citrobacter koseri PM-7: Enhanced production using statistical method and application in ameliorating mineral bioaccessibility and protein digestibility of high-phytate food. AB - The present study was aimed at enhancing phytase (Phy-Ck) production from Citrobacter koseri PM-7 using response surface methodology (RSM) and improving the bioaccessibility of minerals (Fe and Zn) and protein digestibility in high phytate food using Phy-Ck. A five-variable and three-level central composite design of RSM using wheat bran (6.681%, w/v), inoculum level (2.5%, v/v), and triton X-100 (0.2%, v/v) resulted in up to 5.57-fold (1.047 U/ml) improvement in Phy-Ck yield from C. koseri PM-7 when compared with fermentation media I and II. The model was successfully validated in the design space by taking a random set of variable combinations. Treatment of high-phytate food with partially purified Phy-Ck showed improvement in mineral bioaccessibility maximally for defatted sesame flour (DSF) (Fe 45.5%; Zn 50.7%) followed by wheat flour (WF) (Fe 13.5%; Zn 14.4%), green gram flour (GGF) (Fe 0.7%; Zn 3.8%) and defatted groundnut flour (DGF) (Zn 5.6%). The in vitro protein digestibility (IVPD) of WF increased from 48.83 to 65.04%, GGF from 45.04 to 57.12%, and DSF from 47.34 to 55.7% after Phy Ck treatment. PMID- 29194016 TI - Assessment of occupational exposure to asbestos fibers: Contribution of analytical transmission electron microscopy analysis and comparison with phase contrast microscopy. AB - From November 2009 to October 2010, the French general directorate for labor organized a large field-study using analytical transmission electron microscopy (ATEM) to characterize occupational exposure to asbestos fibers during work on asbestos containing materials (ACM). The primary objective of this study was to establish a method and to validate the feasibility of using ATEM for the analysis of airborne asbestos of individual filters sampled in various occupational environments. For each sampling event, ATEM data were compared to those obtained by phase-contrast optical microscopy (PCOM), the WHO-recommended reference technique. A total of 265 results were obtained from 29 construction sites where workers were in contact with ACM. Data were sorted depending on the combination of the ACM type and the removal technique. For each "ACM-removal technique" combination, ATEM data were used to compute statistical indicators on short, fine and WHO asbestos fibers. Moreover, exposure was assessed taking into account the use of respiratory protective devices (RPD). As in previous studies, no simple relationship was found between results by PCOM and ATEM counting methods. Some ACM, such as asbestos-containing plasters, generated very high dust levels, and some techniques generated considerable levels of dust whatever the ACM treated. On the basis of these observations, recommendations were made to measure and control the occupational exposure limit. General prevention measures to be taken during work with ACM are also suggested. Finally, it is necessary to continue acquiring knowledge, in particular regarding RPD and the dust levels measured by ATEM for the activities not evaluated during this study. PMID- 29194017 TI - Rhizomucor miehei lipase immobilized on reinforced chitosan-chitin nanowhiskers support for synthesis of eugenyl benzoate. AB - An alternative environmentally benign support was prepared from chitosan-chitin nanowhiskers (CS/CNWs) for covalent immobilization of Rhizomucor miehei lipase (RML) to increase the operational stability and recyclability of RML in synthesizing eugenyl benzoate. The CS/CNWs support and RML-CS/CNWs were characterized using X-ray diffraction, fluorescent microscopy, and Fourier transform infrared spectroscopy. Efficiency of the RML-CS/CNWs was compared to the free RML to synthesize eugenyl benzoate for parameters: reaction temperature, stirring rate, reusability, and thermal stability. Under optimal experimental conditions (50 degrees C, 250 rpm, catalyst loading 3 mg/mL), a twofold increase in yield of eugenyl benzoate was observed for RML-CS/CNWs as compared to free RML, with the former achieving maximum yield of the ester at 62.1% after 5 hr. Results demonstrated that the strategy adopted to prepare RML-CS/CNWs was useful, producing an improved and prospectively greener biocatalyst that supported a sustainable process to prepare eugenyl benzoate. Moreover, RML-CS/CNWs are biodegradable and perform esterification reactions under ambient conditions as compared to the less eco-friendly conventional acid catalyst. This research provides a facile and promising approach for improving activity of RML in which the resultant RML-CS/CNWs demonstrated good operational stability for up to eight successive esterification cycles to synthesize eugenyl benzoate.

AB - Filtering Facepiece Respirator (FFR) is the most common respirator users in the health care environment utilize for personal protection from outside particles. Comfort and fit are important while wearing an FFR. This paper proposes a novel technology to produce customized face seal design for improving the wearing comfort and fit of FFR wearers. In order to customize the design of face seals, we scanned the faces of three subjects using three-dimensional (3D) laser scanning method. A customized face seal for a 3M 8210 N95 FFR for each headform was designed using reverse engineering technique. Next, the face seal prototypes were fabricated with Acrylonitrile Butadiene Styrene (ABS) plastic using the 3D printing method. A force sensing system based on Arduino Uno R3 was developed, and the force sensor of this system was inserted between the FFR and headform to measure contact pressure. Experimental results showed that the newly designed FFR face seal provided the subjects with an improved contact pressure.

AB - Despite longstanding recommendations for routine vaccination against influenza; pneumococcal; tetanus, diphtheria, acellular pertussis (Tdap); and herpes zoster (HZ) among the United States general adult population, vaccine uptake remains low. Understanding factors that influence adult vaccination and coverage variability beyond the national level are important steps toward developing targeted strategies for increasing vaccination coverage. A retrospective analysis was conducted using data from the Behavioral Risk Factor Surveillance System (2011-2014). Multivariable logistic regression modeling was employed to identify individual factors associated with vaccination (socio-demographics, health status, healthcare utilization, state of residence) and generate adjusted vaccination coverage and compliance estimates nationally and by state. Results indicated that multiple characteristics were consistently associated with a higher likelihood of vaccination across all four vaccines, including female sex, increased educational attainment, and annual household income. Model-adjusted vaccination coverage estimates varied widely by state, with inter-state variability for the most recent year of data as follows: influenza (aged >=18 years) 30.2-49.5%; pneumococcal (aged >=65 years) 64.0-74.7%; Tdap (aged >=18 years) 18.7-46.6%; and HZ (aged >=60 years) 21.3-42.9%. Model-adjusted compliance with age-appropriate recommendations across vaccines was low and also varied by state: influenza+Tdap (aged 18-59 years) 7.9-24.7%; influenza+Tdap+HZ (aged 60-64 years) 4.1-14.4%; and influenza+Tdap+HZ+pneumococcal (aged >=65 years) 3.0-18.3%. In summary, after adjusting for individual characteristics associated with vaccination, substantial heterogeneity across states remained, suggesting that other local factors (e.g. state policies) may be impacting adult vaccines uptake. Further research is needed to understand such factors, focusing on differences between states with high versus low vaccination coverage.

AB - A novel and effective process was put forward for converting rice straw into feed by combining diluted acid hydrolysis and ammonization with Rhodospirillum rubrum fermentation. After pretreatment with dilute sulfuric or phosphoric acid (1%, w/w) at 100 degrees C, materials were subjected to fermentation under several gases (N2, CO2, and air) and different light intensities in a 2-L fermentor. The key indexes of feed for fermented materials were estimated and several toxic substances were investigated during the fermentation. Following sulfuric acid treatment, the true protein of rice straw increased from 29 to 143 g kg-1 and the crude fiber decreased from 359 to 136 g kg-1 after fermentation at 0.3 L min-1 L 1 of N2 flow and a light intensity of 3400 lux; and following phosphoric acid treatment, the true protein increased by 286% and the crude fiber decreased by 52% after fermentation at 0.4 L min-1 L-1 of N2 flow and a light intensity of 3000 lux. Other key contents were also improved for use as feed, and some toxic substances (i.e., furfural, hydroxymethylfurfural, acetic acid, phenol, cresol) produced by the pretreatments could be removed at low levels during the fermentations. PMID- 29194021 TI - A retrospective analysis of nickel exposure data at a South African base metal refinery. AB - This study aimed to analyze historical soluble nickel exposure data from a South African base metal refinery and to identify trends in the soluble nickel exposure from 1981 until 2014 in the electrowinning department. Exposure data were presented in an exposure matrix, which described exposure profiles for both area and personal exposures inside two tankhouses. Exposure data were standardized by converting total nickel aerosol concentrations to inhalable nickel concentrations (correction factor 3.0). One-way analyses of variances (ANOVA) were conducted to identify significant differences in log-transformed area and personal exposures from 1982 until 2014, and the trends were assessed with linear regression. Differences were evaluated in area exposure between sections inside the tankhouses, i.e., East, West, and Center bays and in personal exposure between occupations, i.e., cell workers, crane drivers, and supervisors. Area exposure in Tankhouse 1 declined significantly (p <= 0.0001) between 1982 and 1986 with a factor of 29. However, after 1986 no significant downward trend in area exposure was evident in Tankhouse 1. Personal exposures in Tankhouse 1 significantly (p <= 0.0001) decreased with a factor of three between 1991 and 2014. No significant trends were evident in area and personal exposure in Tankhouse 2. Downward exposure trends were evident in Tankhouse 1 and may be ascribed to the implementation of various control measures and process changes, e.g., increasing polypropylene bead load. Limited data were available for Tankhouse 2, therefore, no trend in exposure could be established. Retrospective analyses may be used to identify trends and anomalies in exposure which might not have been identified during daily exposure monitoring. PMID- 29194022 TI - Resumes en Francais.

AB - This study aimed to understand and describe the views of family members and direct support staff regarding the use of Facebook by persons with intellectual disability (ID) within the context of social capital. In-depth, semistructured interviews conducted with 16 family members and direct support staff of persons with ID who use Facebook revealed that most participants favored Facebook use by persons with ID for bonding and bridging social capital and for normalization. Most participants noted the empowering effect of online activity on persons with ID, yet some reported risks and usage difficulties. Although Facebook use enhances the well-being of persons with ID, findings highlighted the participants' need for formal guidelines regarding social media best-practices for people with ID. PMID- 29194024 TI - Adapting the Mullen Scales of Early Learning for a Standardized Measure of Development in Children With Rett Syndrome. AB - Rett Syndrome (RTT) is characterized by severe impairment in fine motor (FM) and expressive language (EL) function, making accurate evaluations of development difficult with standardized assessm ents. In this study, the administration and scoring of the Mullen Scales of Early Learning (MSEL) were adapted to eliminate the confounding effects of FM and EL impairments in assessing development. Forty seven girls with RTT were assessed with the Adapted-MSEL (MSEL-A), a subset (n = 30) was also assessed using the Vineland Adaptive Behavior Scales-Second Edition (Vineland-II) and a further subset (n = 17) was assessed using an eye-tracking version of the MSEL (MSEL-ET). Participants performed better on the visual reception (VR) and receptive language (RL) domains compared to the FM and EL domains on the MSEL-A. Individual performance on each domain was independent of other domains. Corresponding MSEL-A and Vineland-II domains were significantly correlated. The MSEL-ET was as accurate as the MSEL-A in assessing VR and RL, yet took a 44% less time. Results suggested that the MSEL-A and the MSEL-ET could be viable measures for accurately assessing developmental domains in children with RTT. PMID- 29194025 TI - Self-Advocacy Services for People With Intellectual and Developmental Disabilities: A National Analysis. AB - Self-advocacy plays an important role in facilitating the empowerment of people with intellectual and developmental disabilities (IDD), and helps people with IDD develop the skills necessary for the participant direction of services. The purpose of this study was to examine Medicaid Home and Community Based Services (HCBS) 1915(c) waivers across the nation to determine how states were utilizing self-advocacy services for people with IDD. Findings revealed approximately half of waivers provided self-advocacy services; however, less than .01% of waiver spending was projected for stand-alone self-advocacy services. States need to expand the provision of self-advocacy services for people with IDD in order to strengthen their ability to direct their waiver services and exercise their rights.

AB - Research in centers for people with intellectual and developmental disabilities has somewhat neglected the relationship between workers' burnout and users' service evaluations. Two independent survey studies tested this connection. In the first study (100 centers, 714 workers, and 612 family members), results confirmed that burnout has a negative relationship with workers' perceptions of service quality. In turn, these perceptions are associated with the service quality perceptions of family members and their satisfaction with the service. In a replication sample (86 centers, 601 workers, and 819 family members), we reproduced these results and added situational constraints in the model. Both social and technical constraints correlated positively and significantly with burnout. These studies offer a view of the relationships between burnout and service quality.

AB - Supported decision making has received increased attention as an alternative to guardianship and a means to enable people with intellectual and developmental disabilities to exercise their right to legal capacity. Assessments are needed that can used by people with disabilities and their systems of supports to identify and plan for needed supports to enable decision making. This article describes the steps taken to develop such an assessment tool, the Supported Decision Making Inventory System (SDMIS), and initial feedback received from self advocates with intellectual disability. The three sections of the SDMIS (Supported Decision Making Personal Factors Inventory, Supported Decision Making Environmental Demands Inventory, and Decision Making Autonomy Inventory) are described and implications for future research, policy, and practice are discussed.

AB - Dysphagia (feeding and swallowing disorder) is associated with serious health complications and psychosocial sequelae. This review summarizes international research relating to the prevalence of dysphagia in people with intellectual disability. Studies published from 1990 to July 2016 were identified using Medline, Cinahl, PsycINFO, Web of Science, email requests, and cross-citations. Twenty studies were identified. Dysphagia in people with intellectual disability appears to be associated with more severe levels of intellectual disability, comorbid cerebral palsy, and motor impairments. However, further research with representative samples of people with intellectual disability using adequate methods of assessment are required in order to provide more precise prevalence estimates and clarify factors that may be associated with dysphagia in this population. PMID- 29194032 TI - Phlebotomus (Paraphlebotomus) chabaudi and Phlebotomus riouxi: closely related species or synonyms? AB - Phlebotomus riouxi Depaquit, Killick-Kendrick & Leger 1998 was described as a species closely related to Phlebotomus chabaudi Croset, Abonnenc & Rioux 1970, differing mainly by the size and number of setae of the coxite basal lobe. Molecular studies carried out on several populations from Algeria and Tunisia and based on mitochondrial genes cytochrome b (Cytb) and cytochrome oxidase I (COI) supported the typological validity of these two species. Recently, specimens from a single population in southern Tunisia were morphologically identified as Ph. riouxi, Ph. chabaudi and intermediates, but were clustered in the same clade according to their Cytb and nuclear gene elongation factor-1 alpha (EF-1alpha) sequences. These species were thus synonymized. To further explore this synonymy, we carried out a molecular study on specimens from Algeria and Tunisia using the same molecular markers and a part of 28S rDNA. We did not find any morphologically intermediate specimens in our sampling. We highlighted differences between the genetic divergence rates within and between the two species for the three markers and we identified new haplotypes. The sequence analysis did not reveal any signature of introgression in allopatric nor in sympatric populations such as in the Ghomrassen population. Phylogenetic analyses based on our specimens revealed that the two main clades are Ph. chabaudi and Ph. riouxi, in agreement with the morphological identification. These results support the validity of Ph. riouxi and Ph. chabaudi as typological species. PMID- 29194033 TI - Immunoproteomic analysis of the protein repertoire of unsporulated Eimeria tenella oocysts. AB - The apicomplexan protozoans Eimeria spp. cause coccidioses, the most common intestinal diseases in chickens. Coccidiosis is associated with significant animal welfare issues and has a high economic impact on the poultry industry. Lack of a full understanding of immunogenic molecules and their precise functions involved in the Eimeria life cycles may limit development of effective vaccines and drug therapies. In this study, immunoproteomic approaches were used to define the antigenic protein repertoire from the total proteins of unsporulated Eimeria tenella oocysts. Approximately 101 protein spots were recognized in sera from chickens infected experimentally with E. tenella. Forty-six spots of unsporulated oocysts were excised from preparative gels and identified by matrix-assisted laser desorption ionization time-of-flight MS (MALDI-TOF-MS) and MALDI-TOF/TOF MS. For unsporulated oocysts, 13 known proteins of E. tenella and 17 homologous proteins to other apicomplexan or protozoan parasites were identified using the 'Mascot' server. The remaining proteins were searched against the E. tenella protein sequence database using the 'Mascot in-house' search engine (version 2.1) in automated mode, and 12 unknown proteins were identified. The amino acid sequences of the unknown proteins were searched using BLAST against non-redundant sequence databases (NCBI), and 9 homologous proteins in unsporulated oocyst were found homologous to proteins of other apicomplexan parasites. These findings may provide useful evidence for understanding parasite biology, pathogenesis, immunogenicity and immune evasion mechanisms of E. tenella. PMID- 29194034 TI - Redescription of Cichlidogyrus philander (Monogenea, Ancyrocephalidae) using scanning electron microscopy (SEM) and molecular analysis. AB - The sclerotized structures of monogeneans have traditionally been studied by light microscopy and different staining techniques. Recently, enzymatic digestion followed by scanning electron microscopy (SEM) has enabled the examination of structural details not visible with light microscopy. In order to obtain better, and more accurate, morphological information on sclerotized structures not affected by mounting medium or cover slip pressure, the sclerites of Cichlidogyrus philander Douellou, 1993 (Monogenea, Ancyrocephalidae), collected from Pseudocrenilabrus philander (Weber, 1897), were redescribed using SEM. Parasites were collected from Padda Dam, Gauteng, South Africa and soft tissue was digested to release the sclerotized structures. The digested tissue also provided sufficient genetic material for molecular characterization of this species. Cichlidogyrus philander is characterised by a penis with a sharp, curved, lateral termination, an accessory piece with a hook-like extremity that may appear forked terminally, and lack of a visible vagina. The transverse bars have concave and convex surfaces with ribs on the concave surface. The dorsal bar bears fenestrations at the base of the auricles and the ventral and dorsal gripi are dissimilar. Furthermore, the large first pair of uncinuli shows lateral wings on the left side of the base. On top of this wing, a ball-like structure with a small fenestration is visible. Genetic characters derived from the 28S rDNA, the COI mitochondrial DNA and ITS1 rDNA regions distinguish C. philander from all other Cichlidogyrus sequenced species. PMID- 29194035 TI - The long non-coding RNA CRNDE promotes cervical cancer cell growth and metastasis. AB - This study was intended to analyze effects of lncRNA CRNDE on cervical cancer cell growth and metastasis. Fifty pairs of cervical cancer tissues and corresponding adjacent tissues were collected. Expressions of long non-coding RNAs (lncRNAs) in tissue samples were detected by microarray analysis. Expression levels of CRNDE in cervical cancer cells and normal cells were detected by qRT PCR. Cell-counting kit-8 (CCK-8) assay and clone formation assay were utilized to evaluate cell growth. Wound healing assay and Transwell assay were conducted to detect the migratory and invasive capability of cervical cancer cells. The expressions of CRNDE in cervical cancer tissues and cells were higher than those in normal tissues and cells. CCK-8 assay and clone formation assay showed that the knockdown of CRNDE could inhibit the cell proliferation of HeLa and C-33A cells. Wound healing assay indicated that the downregulation of CRNDE expression could suppress the cell migration. The result of a Transwell assay demonstrated that the number of invasion cells reduced in the CRNDE-si group in comparison with the Mock group. LncRNA CRNDE could promote the cell growth and stimulate the metastasis of cervical cancer cells. PMID- 29194036 TI - Prognostic and predictive value of EGFR and EGFR-ligands in blood of breast cancer patients: a systematic review. AB - Epidermal growth factor receptor (EGFR) serves as a co-target for dual/pan-EGFR inhibitors in breast cancer. Findings suggest that EGFR and EGFR-ligands are involved in resistance towards certain breast cancer treatments. The aim is to explore the validity of EGFR and EGFR-ligands in blood as prognostic and predictive biomarkers in breast cancer. The systematic review was conducted in accordance to the PRISMA guidelines. Literature searches were conducted to identify publications exploring correlations between EGFR/EGFR-ligands in serum/plasma of breast cancer patients and prognostic/predictive outcome measures. Sixteen publications were eligible for inclusion. Twelve studies evaluated EGFR, whereas five studies evaluated one or more of the EGFR-ligands. Current evidence indicates associations between low baseline serum-EGFR and shorter survival or reduced response to treatment in patients with advanced breast cancer, especially in patients with estrogen and/or progesterone receptor positive tumors. The prognostic and predictive value of EGFR and EGFR-ligands in blood has only been investigated in highly selected subsets of breast cancer patients and most studies were small. This is the first systematic review evaluating the utility of EGFR and EGFR-ligands as predictive and prognostic biomarkers in blood in breast cancer. Further exploration in large well-designed studies is needed. PMID- 29194037 TI - Serum prolactin levels across pregnancy and the establishment of reference intervals. AB - BACKGROUND: Reference intervals (RIs) play key roles in clinical diagnosis, treatment and prognosis. However, RIs for clinical testing tend to be confined to the general population, and RIs for pregnant women are not very comprehensive. In this study, we establish RIs for prolactin (PRL) in healthy pregnant and postpartum women in the Chinese population. METHODS: Healthy pregnant women (n=378) were divided into groups according to whether they were in the first, second or third trimester of pregnancy. Healthy postpartum women (n=493) were separated into four groups according to mode of delivery as follows: postvaginal (24 and 48 h) or postcesarean (24 and 48 h). Healthy, non-pregnant women (n=123) were enrolled as a control group. Serum PRL levels were measured by electrochemiluminescence immunoassay, and RIs were established for each group. RESULTS: The RIs for PRL were as follows: healthy non-pregnant women, 178.89 757.52 MUIU/mL; first trimester, 621.20-3584.00 MUIU/mL; second trimester, 1432.00-5349.68 MUIU/mL; third trimester, 4087.33-9733.65 MUIU/mL; 24 and 48 h postvaginal delivery (combined), 7865.36-10998.86 MUIU/mL; and 24 and 48 h postcesarean delivery, 4556.41-7675.99 and 6578.45-9980.45 MUIU/mL, respectively. CONCLUSIONS: PRL RIs for pregnant women were established according to trimester, days postpartum and mode of delivery, thus providing a clinical reference for medical staff. PMID- 29194038 TI - Commutability of control materials for external quality assessment of serum apolipoprotein A-I measurement. AB - BACKGROUND: The aim of the current study was to evaluate the commutability of commercial control materials and human serum pools and to investigate the suitability of the materials for the external quality assessment (EQA) of serum apolipoprotein A-I (apo A-I) measurement. METHODS: The Clinical and Laboratory Standards Institute (CLSI) EP14-A3 protocol was used for the commutability study. Apo A-I concentrations in two levels of commercial control materials used in EQA program, two fresh-frozen human serum pools (FSPs) and two frozen human serum pools prepared from residual clinical specimens (RSPs) were measured along with 50 individual samples using nine commercial assays. Measurement results of the 50 individual samples obtained with different assays were pairwise analyzed by Deming regression, and 95% prediction intervals (PIs) were calculated. The commutability of the processed materials was evaluated by comparing the measurement results of the materials with the limits of the PIs. RESULTS: The FSP 1 was commutable for all the 36 assay pairs, and FSP-2 was commutable for 30 pairs; RSP-1 and RSP-2 showed commutability for 27/36 and 22/36 assay pairs, respectively, whereas the two EQA materials were commutable only for 4/36 and 5/36 assay pairs, respectively. CONCLUSIONS: Non-commutability of the tested EQA materials has been observed among current apo A-I assays. EQA programs need either to take into account the commutability-related biases in the interpretation of the EQA results or to use more commutable materials. Frozen human serum pools were commutable for most of the assays. PMID- 29194039 TI - Validation of a high-performance liquid chromatography method for thiopurine S methyltransferase activity in whole blood using 6-mercaptopurine as substrate. AB - BACKGROUND: Variation in metabolism, toxicity and therapeutic efficacy of thiopurine drugs is largely influenced by genetic polymorphisms in the thiopurine S-methyltransferase (TPMT) gene. Determination of TPMT activity is routinely performed in patients to adjust drug therapy. METHODS: We further optimized a previously established high-performance liquid chromatography (HPLC) method by measuring TPMT activity in whole blood instead of isolated erythrocytes, which is based on conversion of 6-mercaptopurine to 6-methylmercaptopurine using S adenosyl-methionine as methyl donor. RESULTS: The simplified TPMT whole-blood method showed similar or better analytical and diagnostic performance compared with the former erythrocyte assay. The whole-blood method was linear for TPMT activities between 0 and 40 nmol/(mL.h) with a quantification limit of 0.1 nmol/(mL.h). Within-day imprecision and between-day imprecision were <=5.1% and <=8.5%, respectively. The optimized method determining TPMT activity in whole blood (y) showed agreement with the former method determining TPMT activity in erythrocytes (x) (n=45, y=1.218+0.882x; p>0.05). Phenotype-genotype concordance (n=300) of the whole-blood method was better when TPMT activity was expressed per volume of whole blood (specificity 92.2%), whereas correction for hematocrit resulted in lower genotype concordance (specificity 86.9%). A new cutoff for the whole-blood method to distinguish normal from reduced TPMT activity was determined at <=6.7 nmol/(mL.h). CONCLUSIONS: This optimized TPMT phenotyping assay from whole blood using 6-MP as substrate is suitable for research and routine clinical analysis. PMID- 29194040 TI - Effect of preanalytical and analytical variables on the clinical utility of mean platelet volume. AB - BACKGROUND: The study endpoint was to analyze the effect of preanalytical (time, temperature, anticoagulant) and analytical (imprecision, correlation between volume and platelet concentration) variables on mean platelet volume (MPV). A further aim was to calculate in an adult population the reference intervals using the Sysmex XE-5000 analyzer. A critical evaluation was also made of the clinical utility of these parameters. METHODS: Analyses of the above values were performed in duplicate in 170 healthy adults of both sexes: (1) within 30 min from collection, and (2) after 4 h. To evaluate stability over time, the value of the platelet parameters of 20 subjects were determined, a re-analysis being performed for a period of up to 24 h on samples maintained at room temperature and 4 degrees C using either K2-EDTA or Na-citrate as anticoagulants. RESULTS: The stability over time of MPV closely depends on the anticoagulant used, storage temperature and time interval between venipuncture and analysis. An inverse, non linear correlation between MPV and platelet count was also found. CONCLUSIONS: In view of their effect on MPV and other related indices, the preanalytical and analytical variables make them, little more than experimental.

PMID- 29194043 TI - The role of corticosteroid-binding globulin in the evaluation of adrenal insufficiency. AB - Cortisol is a hydrophobic molecule that is largely bound to corticosteroid binding globulin (CBG) in the circulation. In the assessment of adrenal insufficiency, many clinicians measure a total serum cortisol level, which assumes that CBG is present in normal concentrations and with a normal binding affinity for cortisol. CBG concentration and affinity are affected by a number of common factors including oral contraceptive pills (OCPs), fever and infection, as well as rare mutations in the serine protease inhibitor A6 (SERPINA6) gene, and as such, total cortisol levels might not be the ideal way to assess adrenal function in all clinical circumstances. This paper reviews the limitations of immunoassay and liquid chromatography-tandem mass spectrometry (LC-MS/MS) in the measurement of total cortisol, the challenges of measuring free serum cortisol directly as well as the difficulties in calculating an estimated free cortisol from total cortisol, CBG and albumin concentrations. Newer approaches to the evaluation of adrenal insufficiency, including the measurement of cortisol and cortisone in the saliva, are discussed and a possible future role for these tests is proposed.

CASE PRESENTATION: We report a patient with hypoglycemia, precocious puberty and diffuse testicular microlithiasis accompanying BRRS, and think that this case is important in the light of a newly identified mutation in the PTEN gene. CONCLUSIONS: Close attention must be paid in terms of PTEN mutations in cases of macrocephaly and accompanying neurological and dermatological findings. PMID- 29194045 TI - Mothering under the influence: how perinatal drugs of abuse alter the mother infant interaction. AB - Although drug-abusing women try to moderate their drug and alcohol use during pregnancy, they often relapse at a time when childcare needs are high and maternal bonding is critical to an infant's development. In the clinical setting, the search for the neural basis of drug-induced caregiving deficits is complex due to several intervening variables. Rather, the preclinical studies that control for drug dose and regimen, as well as for gestational and postpartum environment, allow a precise determination of the effects of drugs on maternal behaviour. Given the relevance of the issue, this review will gather reports on the phenotypic correlates of maternal behaviour in preclinical studies, and focus on the detrimental consequences on the mother-infant interaction exerted by the perinatal use of alcohol, nicotine, cannabis, cocaine and stimulants and opiates. The drug-induced disruptions of this maternal repertoire are associated with adverse maternal and infant outcomes. A comprehensive overview will help promote the refinement of the treatment approaches toward maternal drug use disorders and maternal misbehaviour, in favour of augmented parenting resiliency. PMID- 29194046 TI - Updates on the biology of serotonin and tryptophan hydroxylase. AB - PURPOSE OF REVIEW: To summarize the most recent findings relevant to the biology of serotonin (5-hydroxytryptamine; 5-HT) and the enzyme tryptophan hydroxylase (TPH) in human gastrointestinal disease. RECENT FINDINGS: Serotonin is synthesized in the central nervous system (CNS) and the gastrointestinal tract where it is secreted from enteroendocrine cells. Its biosynthesis is regulated by two isoforms of the enzyme TPH of which TPH1 is localized predominantly in gastrointestinal enteroendocrine cells. Serotonin activates the peristaltic reflexes, regulates gastrointestinal motility, and has a role in intestinal inflammation. Inhibition of TPH with novel molecules represents a new pharmacological tool in the successful management of carcinoid syndrome in patients with gastrointestinal neuroendocrine tumors (GI-NETs). Certain 5-HT receptor subtype agonists and antagonists are useful in the treatment of functional gastrointestinal disorders. SUMMARY: The gastrointestinal tract is the largest storage organ for serotonin where its biosynthesis is regulated by TPH1. It has several important functions in gastrointestinal motility, secretion, and inflammation. Furthermore, TPH represents a target for inhibitory pharmacological therapy of serotonin access states such as the carcinoid syndrome.

PMID- 29194048 TI - New Swallowing Method to Improve Pharyngeal Passage of a Bolus by Creating Negative Pressure in the Esophagus-Vacuum Swallowing. AB - Herein, we present a case of a patient with Wallenberg syndrome with severe bulbar dysphagia who discovered a unique swallowing method: creating strong negative pressure in the esophagus to improve pharyngeal passage of a bolus. A 47 yr-old man presented with a subarachnoid hemorrhage secondary to a ruptured aneurysm in the right vertebral artery. After coil embolization, he experienced severe dysphagia due to Wallenberg syndrome and required tube feeding. Eighty-one days after the onset of the stroke, a videofluoroscopic swallowing evaluation revealed that the bolus was rapidly sucked into the esophagus. High-resolution manometry showed weak constriction of the pharynx simultaneous with forced, voluntary constriction of the diaphragm before swallowing; this created negative pressure in the esophagus. The authors named this unique swallowing method "vacuum swallowing." Ultimately, the patient was able to eat an ordinary diet via the use of this technique. Vacuum swallowing is a unique method of improving pharyngeal passage of a bolus by creating strong negative pressure in the esophagus. Additional studies are necessary to determine whether vacuum swallowing can be successfully used for other forms of dysphagia. PMID- 29194049 TI - Preserving the Shoulder Function of an Elite Para Triathlete: A Case Report. AB - Shoulder pain in wheelchair users that participate in competitive adaptive sports can be a troublesome condition. Shoulder pain not only affects athletic performance, but also functional activities such as wheelchair propulsion and weight bearing during transfers. Managing pain in these athletes thus presents a unique challenge due to the difficulty in achieving relative rest and the need to modify athletic shoulder-focused rehabilitation strategies. In all athletes, it is vital to establish an early, accurate diagnosis and optimize conservative treatment prior to considering surgical interventions in order to avoid excessive shoulder-related morbidity, loss of function, and worse - loss of independence.

AB - PURPOSE OF REVIEW: We provide a concise review of recent studies focusing on the management of patients with acute heart failure (AHF). RECENT FINDINGS: In well designed randomized trials, no mortality benefit has been observed with the use of diuretics, ultrafiltration, inotropes and vasodilators in AHF. Recent trials examining the role of novel inotropes and vasodilators as well as the role of mineralocorticoid receptor antagonists in the AHF population, is reviewed. SUMMARY: The focus of therapy in AHF should be directed towards symptom management. No mortality benefit has been observed despite good quality studies. PMID- 29194051 TI - Blood, tissue and imaging biomarkers in calcific aortic valve stenosis: past, present and future. AB - PURPOSE OF REVIEW: Calcific aortic valve stenosis is the most prevalent valvular heart disease in the high-income countries. To this date, no medical therapy has been proven to prevent or to stop the progression of aortic valve stenosis. The physiopathology of aortic valve stenosis is highly complex and involves several signalling pathways, as well as genetic related factors, which delay the elaboration of effective pharmacotherapies. Moreover, it is difficult to predict accurately the progression of the valve stenosis and finding the optimal timing for aortic valve replacement remains challenging. Therefore, the present review makes an inventory of the most recent and promising circulating and imaging biomarkers related to the underlying mechanisms involved in the physiopathology of aortic valve stenosis, as well as the biomarkers associated with the left ventricular (LV) remodelling and subsequent dysfunction in patients with aortic valve stenosis. RECENT FINDINGS: Over the last decade, several blood, tissue and imaging biomarkers have been investigated in aortic valve stenosis patients. At the aortic valve level, these biomarkers are mostly associated and/or involved with processes such as lipid infiltration and oxidation, chronic inflammation and fibrocalcific remodelling of the valve. Moreover, recent findings suggest that aging and sex hormones might interact with these multiple processes. Several studies demonstrated the usefulness of circulating biomarkers such as lipoprotein(a), brain natriuretic peptides and high-sensitivity cardiac troponin, which are very close to clinical routine. Furthermore, noninvasive imaging biomarkers including positron emission tomography and cardiac magnetic resonance, which provide a detailed view of the disease activity within the aortic valve and its repercussion on the left ventricle, may help to improve the understanding of aortic valve stenosis physiopathology and enhance the risk stratification. Other biomarkers such as von Willebrand factor and microRNAs are promising but further studies are needed to prove their additive value in aortic valve stenosis. SUMMARY: Most of the biomarkers are used in research and thus, are still being investigated. However, some biomarkers including plasma level of lipoprotein(a), F-sodium fluoride, brain natriuretic peptides and high-sensitivity cardiac troponin can be or are very close to be used for the clinical management of patients with aortic valve stenosis. Moreover, a multibiomarker approach might provide a more global view of the disease activity and improve the management strategies of these patients.

AB - PURPOSE OF REVIEW: The aim of this review is to present an up-to-date overview of the application of machine learning methods in heart failure including diagnosis, classification, readmissions and medication adherence. RECENT FINDINGS: Recent studies have shown that the application of machine learning techniques may have the potential to improve heart failure outcomes and management, including cost savings by improving existing diagnostic and treatment support systems. Recently developed deep learning methods are expected to yield even better performance than traditional machine learning techniques in performing complex tasks by learning the intricate patterns hidden in big medical data. SUMMARY: The review summarizes the recent developments in the application of machine and deep learning methods in heart failure management. PMID- 29194053 TI - Cervical Injuries in Drowning Cases: A Case Report and a Review of Literature. AB - Discovery of bruises in the muscles of the neck and a fracture of the hyoid bone in a body recovered from water makes the diagnosis and the determination of the manner of death difficult.The aims of this work are to report a case of a drowned body with cervical injuries and to highlight the importance of interpreting these findings accurately.A 39-year-old woman was found dead face down in a 6-m deep well with a 3-m water level. She was mentally disturbed and had a history of suicide attempts. In fact, she had previously attempted to jump into that well in an attempt to put an end to her life. The autopsy revealed bruises in the muscles of the neck and a bruise associated with a fracture of the left horn of the hyoid bone.The mechanism for the origin of drowning-related neck injuries will be discussed. PMID- 29194054 TI - A Rare Vehicle-Assisted Ligature Hanging: Suicide at the Wheel. AB - Suicide by hanging inside a motor vehicle is a rare occurrence. A 48-year-old woman suffering from major depression was found having agonal breathing inside her automobile. A 20-mm diameter blue nylon rope was wrapped tightly around her neck, with its other end tied to a nearby wooden fence post. Despite resuscitation attempts, she was declared deceased after several minutes. The vehicle was located in an area with a slight downward slope. The motor was off. It was in neutral gear, with the parking brake disengaged. Consequently, the gravitational forces, attributable to the mass of the vehicle and the declivity of the terrain, caused the rope to tighten.The dynamics fulfill the criteria for a partial hanging, given the difference in height between the point at which the rope was secured to the post and woman's neck, which in turn presented the typical oblique upward groove.This case, thus, represents a unique mode of partial hanging inside a passenger vehicle, rarely reported in the literature. The relative lack of internal injury is also noteworthy, along with the fact that the victim was discovered while still alive. The latter feature can be explained by the absence of the sudden or violent acceleration forces that can be generated with the engine on. PMID- 29194055 TI - Hinged Lids and Fatal Head Entrapment in Early Childhood. AB - Young children are at risk of head entrapment because they often do not understand potentially dangerous situations or have the intellectual or physical capabilities to self-extricate. Two cases of head entrapment due to hinged lids are presented to demonstrate another rare lethal situation specific to the very young. Case 1 was a 14-month-old boy found suspended by his neck in a semikneeling position under a toilet seat. A horizontal linear bruise measuring 0.6 * 20 mm was present on the right side of the neck with petechial hemorrhages of the forehead. Death was due to neck compression from head entrapment with aspiration of gastric contents. Case 2 was a 17-month-old girl found suspended by her neck from the side of her crib by a hinged cover. A horizontal linear bruise measuring 10 * 50 mm was present immediately below the suprasternal notch with numerous petechial hemorrhages of the conjunctivae and face. Death was due to neck compression from head entrapment. Although these cases are very rare, they do show the potential danger that hinged lids may present to toddlers. Autopsy evaluations require comparisons of injuries with the structure and edges of the entrapping device/object. PMID- 29194056 TI - Neonatal Nurses Experience Unintended Consequences and Risks to Patient Safety With Electronic Health Records. AB - In this article, we examine the unintended consequences of nurses' use of electronic health records. We define these as unforeseen events, change in workflow, or an unanticipated result of implementation and use of electronic health records. Unintended consequences experienced by nurses while using electronic health records have been well researched. However, few studies have focused on neonatal nurses, and it is unclear to what extent unintended consequences threaten patient safety. A new instrument called the Carrington Gephart Unintended Consequences of Electronic Health Record Questionnaire has been validated, and secondary analysis using the tool explored the phenomena among neonatal nurses (N = 40). The purposes of this study were to describe unintended consequences of use of electronic health records for neonatal nurses and to explore relationships between the phenomena and characteristics of the nurse and the electronic health record. The most frequent unintended consequences of electronic health record use were due to interruptions, followed by a heavier workload due to the electronic health record, changes to the workflow, and altered communication patterns. Neonatal nurses used workarounds most often with motivation to better assist patients. Teamwork was moderately related to higher unintended consequences including patient safety risks (r = 0.427, P = .007), system design (r = 0.419, P = .009), and technology barriers (r = 0.431, P = .007). Communication about patients was reduced when patient safety risks were high (r = -0.437, P = .003). By determining the frequency with which neonatal nurses experience unintended consequences of electronic health record use, future research can be targeted to improve electronic health record design through customization, integration, and refinement to support patient safety and better outcomes. PMID- 29194057 TI - Approaches and techniques to avoid development or progression of acute respiratory distress syndrome. AB - PURPOSE OF REVIEW: Despite major improvement in ventilation strategies, hospital mortality and morbidity of the acute respiratory distress syndrome (ARDS) remain high. A lot of therapies have been shown to be ineffective for established ARDS. There is a growing interest in strategies aiming at avoiding development and progression of ARDS. RECENT FINDINGS: Recent advances in this field have explored identification of patients at high-risk, nonspecific measures to limit the risks of inflammation, infection and fluid overload, prevention strategies of ventilator-induced lung injury and patient self-inflicted lung injury, and pharmacological treatments. SUMMARY: There is potential for improvement in the management of patients admitted to intensive care unit to reduce ARDS incidence. Apart from nonspecific measures, prevention of ventilator-induced lung injury and patient self-inflicted lung injury are of major importance. PMID- 29194058 TI - Gait Deviations Associated With Concussion: A Systematic Review. AB - BACKGROUND: Gait deviations resulting from concussion are important to consider in the diagnosis, treatment progression, and return to activity after a concussion. OBJECTIVE: To identify quantifiable gait deviations associated with concussion across populations and time since injury. METHODS AND MATERIALS: Six electronic databases were systematically searched from January 1974 to September 2016. Studies selected included original data, had an analytic design, and reported a quantifiable gait parameter in individuals who had sustained a concussion as defined by the American Congress of Rehabilitation Medicine or related definitions. Preferred Reporting Items for Systematic reviews and Meta Analysis guidelines were followed. Two independent authors assessed study quality [Downs and Black (DB) criteria] and level of evidence (Oxford Center of Evidence Based Medicine Model). RESULTS: Of 2650 potentially relevant articles, 21 level 4 studies were included. The median DB score was 12/33 (range 10-16). Heterogeneity in gait parameters and timing of postconcussion testing precluded meta-analysis. There is consistent level 4 evidence of increased medial-lateral center-of-mass displacement, and inconsistent level 4 evidence of decreased gait velocity after concussion. Further, there is preliminary level 4 evidence that gait deficits may exist beyond the typical 10-day recovery period and return to activity. CONCLUSION: These findings suggest that individuals who have suffered a concussion may sway more in the frontal plane, and walk slower compared to healthy controls. Consensus about the most important gait parameters for concussion diagnosis and clinical management are lacking. Further, high-quality prospective cohort studies evaluating changes in gait from time of concussion to return to activity, sport, recreation and/or work are needed. PMID- 29194059 TI - Self-Reported Mild Traumatic Brain Injuries in Relation to Rumination and Depressive Symptoms: Moderating Role of Sex Differences and a Brain-Derived Neurotrophic Factor Gene Polymorphism. AB - OBJECTIVE: Mild traumatic brain injuries (mTBIs) have frequently been associated with the emergence and persistence of depressive symptoms. However, the factors which contribute to the increased risk for depression after these head injuries remain unclear. Accordingly, we examined the relationship between frequency of self-reported mTBIs and current symptoms of depression and the mediating role of rumination and cognitive flexibility. We also examined whether these relations were moderated by sex differences and the presence of the Val66Met polymorphism in a gene coding for brain-derived neurotrophic factor (BDNF). DESIGN: Retrospective, cross-sectional. SETTING: Carleton University. PARTICIPANTS: Two hundred nineteen Carleton University undergraduate students. MAIN OUTCOME MEASURES: Cognitive flexibility as assessed by the Wisconsin Card Sorting Task (WCST); subtypes of rumination (Ruminative Response Scale; Treynor, Gonzalez, and Nolen-Hoeksema, 2003); depressive symptoms (Beck Depression Inventory; Beck, Ward, and Mendelson, 1961). RESULTS: Greater frequency of self-reported mTBIs was associated with more frequent depressive rumination among women, but not men, which was accompanied by elevated current depressive symptoms. In addition, among Met allele carriers of the BDNF polymorphism, but not those who were Val homozygotes, greater frequency of mTBIs was related to higher levels of brooding, which was accompanied by heightened depressive symptoms. Brain-derived neurotrophic factor genotype also moderated the relationship between self reported mTBIs and cognitive flexibility in that more frequent mTBIs were associated with more perseverative errors on the WCST among Met carriers, but not Val homozygotes. CONCLUSIONS: The present findings raise the possibility that the evolution of depression after mTBIs may be dependant on a BDNF polymorphism and sex differences.

PMID- 29194065 TI - Delayed Respiratory Depression Secondary to Opioid Overdose After Multimodal Analgesia With Transversus Abdominis Plane Blocks in Postanesthesia Care Unit: A Case Report. AB - Pain control after open abdominal surgery often includes multimodal analgesia with thoracic epidural or transversus abdominis plane (TAP) block. After liposomal bupivacaine was approved for TAP blocks in 2015, it became an alternative to indwelling catheters. However, the pharmacokinetics and safety of its use during the perioperative period have not been thoroughly investigated, especially in conjunction with parenteral opioids. We present a case report of an elderly patient having urgent laparoscopic converted to open abdominal surgery, who experienced postoperative respiratory depression in the recovery room after multimodal therapy with liposomal bupivacaine TAP blocks, intravenous (IV) opioids, and ketorolac. PMID- 29194062 TI - Cost-effectiveness Analysis of Intraoperative Cell Salvage for Obstetric Hemorrhage. AB - BACKGROUND: Cost-effectiveness analyses on cell salvage for cesarean delivery to inform national and societal guidelines on obstetric blood management are lacking. This study examined the cost-effectiveness of cell salvage strategies in obstetric hemorrhage from a societal perspective. METHODS: Markov decision analysis modeling compared the cost-effectiveness of three strategies: use of cell salvage for every cesarean delivery, cell salvage use for high-risk cases, and no cell salvage. A societal perspective and lifetime horizon was assumed for the base case of a 26-yr-old primiparous woman presenting for cesarean delivery. Each strategy integrated probabilities of hemorrhage, hysterectomy, transfusion reactions, emergency procedures, and cell salvage utilization; utilities for quality of life; and costs at the societal level. One-way and Monte Carlo probabilistic sensitivity analyses were performed. A threshold of $100,000 per quality-adjusted life-year gained was used as a cost-effectiveness criterion. RESULTS: Cell salvage use for cases at high risk for hemorrhage was cost effective (incremental cost-effectiveness ratio, $34,881 per quality-adjusted life-year gained). Routine cell salvage use for all cesarean deliveries was not cost-effective, costing $415,488 per quality-adjusted life-year gained. Results were not sensitive to individual variation of other model parameters. The probabilistic sensitivity analysis showed that at the $100,000 per quality adjusted life-year gained threshold, there is more than 85% likelihood that cell salvage use for cases at high risk for hemorrhage is favorable. CONCLUSIONS: The use of cell salvage for cases at high risk for obstetric hemorrhage is economically reasonable; routine cell salvage use for all cesarean deliveries is not. These findings can inform the development of public policies such as guidelines on management of obstetric hemorrhage. PMID- 29194066 TI - Exercise as an Intervention to Mitigate Decreased Cognitive Function From Cancer and Cancer Treatment: An Integrative Review. AB - BACKGROUND: Decreased cognitive function associated with non-central nervous system cancers and cancer treatment significantly affects cancer survivors' quality of life. Exercise may be an effective intervention to mitigate decreased cognitive function. OBJECTIVE: The aim of this article is to conduct an integrative review to summarize and critique the available evidence related to the use of exercise as a potential intervention for decreased cognitive function from cancer and cancer treatment. METHODS: We conducted an integrative review through January 2016 utilizing PubMed, CINAHL, and PsycINFO. Broad inclusion criteria included any quantitative study in which cognitive outcomes were reported in relationship to any type of exercise for adult cancer survivors. Effect sizes were calculated when possible based on available data. RESULTS: Twenty-six studies were included for review. The majority of studies (including aerobic or resistance exercise as well as mindfulness-based exercise) were associated with some improved cognitive outcomes. However, studies varied significantly in levels of evidence, cognitive domains assessed, and types of cognitive measures. Less than half of the studies included objective measures of cognitive function. CONCLUSIONS: The evidence shows promising trends for the use of exercise as a potential intervention for improving cognitive function following cancer and cancer treatment, but questions remain concerning exercise type, timing of initiation, intensity, frequency, and duration. IMPLICATIONS FOR PRACTICE: Additional research is warranted to understand how various types of exercise influence cognitive function in the cancer survivor population and to better understand the mechanisms driving these effects. Trial designs that include both objective and subjective measures of cognitive function are needed. PMID- 29194068 TI - Polycythemia vera and essential thrombocythemia: algorithmic approach. AB - PURPOSE OF REVIEW: To describe an algorithm-based approach, whenever available, to the diagnosis, the risk stratification criteria informing therapy and the current management of polycythemia vera and essential thrombocythemia. RECENT FINDINGS: Description of recurrent genetic abnormalities in driver genes, including Janus Kinase 2 (JAK2), myeloproliferative leukemia and calreticulin, a better appreciation of the key diagnostic role of bone marrow features, results of large epidemiologic studies and a few but landmark controlled clinical trials produced in the last decade, all resulted in a reappraisal of the approach to polycythemia vera and essential thrombocythemia. SUMMARY: The revised 2017 WHO classification of polycythemia vera and essential thrombocythemia allows early diagnosis and accurate distinction from other chronic myeloproliferative neoplasms, particulary prefibrotic myelofibrosis. The prognostic value of selected mutations is being appreciated and JAK2V617F mutation is currently incorporated as risk variable in prognostic system for essential thrombocythemia. Risk-adjusted stratification is used to select therapeutic approaches that include target agents. However, there is not yet a curative approach to these hematologic neoplasms, and although their management has much improved in the last decades, the associated morbidity and mortality remains significant and may be worsened by toxicities of therapeutic agents. Therefore, several clinically relevant endpoints remain unmet. PMID- 29194067 TI - Personalized therapy in a GRIN1 mutated girl with intellectual disability and epilepsy. PMID- 29194069 TI - Changing patterns in treatment of angle closure glaucoma. AB - PURPOSE OF REVIEW: Angle closure glaucoma is a leading cause of blindness globally and trends of how best to treat this disease are evolving. The advent of anterior segment imaging aids our understanding of pathogenesis and allows more robust and objective measurement of treatment modalities. We will also review recent literature regarding the role of laser and surgical interventions for the treatment of primary angle closure disease. RECENT FINDINGS: Recent studies evaluating the efficacy of laser peripheral iridotomy (LPI) in primary angle closure suspects (PACs) show that while it is a safe intervention and initially anterior chamber angle widens following the laser treatment, the effect is lost with time. Only a small minority of PACs patients develop primary angle closure (PAC) or primary angle closure glaucoma (PACG). Trials evaluating argon laser peripheral iridoplasty (ALPI) have failed to show a substantial clinical benefit. In patients with early or moderate PACG and those with PAC with IOP over 30 mmHg, clear lens extraction is associated with better clinical and quality of life outcomes than LPI. SUMMARY: Recent evidence supports initial clear lens extraction in the context of PACG or primary angle closure with IOP more than 30 mmHg. PMID- 29194070 TI - Changes in gut microbiota during development of compulsive checking and locomotor sensitization induced by chronic treatment with the dopamine agonist quinpirole. AB - Long-term treatment of rats with the D2/D3 dopamine agonist quinpirole induces compulsive checking (proposed as animal model of obsessive-compulsive disorder) and locomotor sensitization. The mechanisms by which long-term use of quinpirole produces those behavioral transformations are not known. Here we examined whether changes in gut microbiota play a role in these behavioral phenomena, by monitoring the development of compulsive checking and locomotor sensitization at the same time as measuring the response of gut microbiota to chronic quinpirole injections. Two groups of rats received nine injections of saline (n=16) or quinpirole (n=15; 0.25 mg/kg), at weekly intervals for the first 5 weeks and then two injections per week until the end of treatment. After each injection, rats were placed on a large open field for 55 min, and their behavior was video recorded for subsequent analysis. Fecal matter was collected after each trial and frozen for bacterial community profiling of the 16S rRNA gene, using paired-end reads of the V3 region. The results indicated that the induction of locomotor sensitization and compulsive checking was accompanied by changes in several communities of bacteria belonging to the order Clostridiales (class Clostridia, phylum Firmicutes), and predominantly in Lachnospiraceae and Ruminococcaceae families of bacteria. It is suggested that changes in these microbes may serve to support the energy use requirements of compulsive checking and obsessive compulsive disorder. PMID- 29194071 TI - Revisiting the phenotypic and genetic profiling of anergic T cells mediating long term transplant tolerance. AB - PURPOSE OF REVIEW: Herein our focus will be to revisit peripheral tolerance mechanisms and in particular 'active' or 'dominant' tolerance as originally defined and mediated by regulatory CD4FoxP3 T lymphocytes (Treg) and also T-cell anergy that appears as a major mainstay to support long-term allograft survival. RECENT FINDINGS: It is at the same time interesting and rewarding that the tool that recently guided our efforts along this path is the in-vivo use of CD3 antibody, the first monoclonal introduced in the clinic (Orthoclone OKT3) about 35 years ago to treat and prevent rejection of renal allografts. Beyond their immunosuppressive activity, whenever administered judiciously, CD3 antibodies promote robust allograft tolerance through selective purging of alloreactive effectors, resetting Treg-mediated active tolerance and promoting a unique subset of anergic CD8 T cells. SUMMARY: The new findings discussed open up new perspectives from both a fundamental and a clinical point of view. In basic research, concrete molecular signaling paths are now spotted to finely dissect the conditions that lead to the establishment and maintenance of robust T lymphocyte anergy mediating allograft tolerance. In the clinic, this may rapidly translate into novel biomarkers to be used in parallel to the ones already available, to better adapt posttransplant immunotherapy and monitor for long-term allograft acceptance. PMID- 29194072 TI - Prenatal thrombosis of renal veins and the inferior vena cava in a newborn with double heterozygosity for the factor V Leiden and prothrombin gene G20210A mutations: a case report. AB - : Renal vein thrombosis in a neonate is a rare but well recognized condition with low mortality but high morbidity. The cause has not been explained clearly yet but is probably a multifactorial process that includes inherited prothrombotic abnormalities. Antenatal onset of renal vein thrombosis is important due to the increased risk for permanent organ damage. We report a case of prenatal thrombosis of the renal veins and the inferior vena cava in a newborn with double heterozygosity for factor V Leiden and prothrombin gene mutations who had persistently impaired renal function requiring chronic peritoneal dialysis. PMID- 29194073 TI - Update on trends in childhood tuberculosis. AB - PURPOSE OF REVIEW: Although tuberculosis (TB) causes much morbidity and mortality in children, diagnosis and treatment remain challenging. Recently, children have gained increasing attention in research and clinical trials driving improved contact management, case identification and treatment of both drug-susceptible and drug-resistant TB. This review highlights some recent advances. RECENT FINDINGS: The tuberculin skin test is the most widely used test to distinguish Mycobacterium tuberculosis (M. tuberculosis) infection from active TB, however, using M. tuberculosis-specific, antigenic stimulation of CD4 and CD8 cells appear more effective. The use of Xpert MTB/RIF to identify M. tuberculosis in clinical samples, together with novel sampling methods have in part, overcome the difficulty of sampling and increased case identification capacity. Advances in treating both drug-susceptible and drug-resistant childhood TB show promise in being more paediatric friendly and improving adherence. Dosing strategies for drug-sensitive TB have improved with dispersible fixed drug combinations now available. In the treatment and prevention of drug-resistant TB, however, research involving the use of newer and more effective drugs currently recommended for adults, are still ongoing in children. SUMMARY: The World Health Organization aims to end the TB epidemic by 2035 whereas the United Nations' Sustainable Developmental Goals sets this ambitious target for 2030. Therefore, adequate funding and implementing effective national TB programs must be prioritized, particularly in high-burden, low-income settings. PMID- 29194074 TI - Developmental dysplasia of the hip: an update on diagnosis and management from birth to 6 months. AB - PURPOSE OF REVIEW: Our understanding of the epidemiology, diagnosis, and management of developmental dysplasia of the hip (DDH) is evolving. This review focuses on the most up-to-date literature on DDH in patients from birth to six months of age. RECENT FINDINGS: Well known risk factors for DDH include family history, female sex, and breech positioning. Recent evidence suggests higher birth weight is a risk, whereas prematurity may be protective. Screening includes physical examination of all infant hips and imaging when abnormal findings or risk factors are present. Treatment in the first six months consists of a harness, with 70-95% success. Failure risk factors include femoral nerve palsy, static bracing, irreducible hips, initiation after seven weeks of age, right hip dislocation, Graf-IV hips, and male sex. Rigid bracing may be trialed if reduction with a harness fails and closed reduction is indicated after failed bracing. If the hip is still irreducible, nonconcentric, or unstable, open reduction may be required following closed reduction. Evidence does not support delaying hip reduction until the ossific nucleus is present. SUMMARY: DDH affects 1-7% of infants. All infants should be examined and selective screening with imaging should be performed for abnormal physical exams or risk factors. Early treatment is associated with optimal outcomes. PMID- 29194075 TI - Cutaneous angiosarcoma: update on biology and latest treatment. AB - PURPOSE OF REVIEW: The present review aims to provide readers with the latest updates on the biology and clinical management of cutaneous angiosarcoma (cAS). RECENT FINDINGS: The genomic alteration of cAS is heterogeneous. Mutations are enriched in the mitosis-activated kinase (MAPK) pathway. Functional analysis has identified molecules that may serve as potential markers and therapeutic targets of angiosarcoma. These molecules include survivin, HSP90, FOXM1, miR-497-5p, KCa3.1, and miR210.This body of knowledge has not yet transferred to clinical practice. The mainstay of treatment for cAS remains surgery followed by postoperative radiotherapy. The efficacy of paclitaxel as an adjuvant chemotherapy is suggested.For patients with advanced cAS, paclitaxel is the treatment of choice. There are also second-line treatment options that are supported by evidence of varying strength. A multikinase inhibitor, pazopanib, has been assessed in several studies, most of which support its efficacy for angiosarcoma. Bevacizumab monotherapy may be effective for angiosarcoma. The efficacy of eribulin mesylate and trabectedin for angiosarcoma is currently being assessed. Recent publications highlighted the role of the immune system in the biology of cAS. SUMMARY: Future research efforts should focus on the following aspects of cAS: drug development directed at recent molecular targets, clinical trials designed specifically for patients with cAS, and the role of immunotherapy for cAS. PMID- 29194076 TI - Morcellation equipment: past, present, and future. AB - PURPOSE OF REVIEW: This review was written in an effort to describe the evolution of power morcellation equipment from their creation to their current state. In addition, this review addresses the continuously evolving equipment involved with power morcellation and looks to describe where the field is headed in the future. In addition, recent professional and federal recommendations have changed the way power morcellation is being approached and has led to the development of contained morcellation systems, which, although in their infancy, are also being proven to be well tolerated options. RECENT FINDINGS: This article will review the most current research on electronic power morcellation and the multiple attempts to prove superiority from the many different types of equipment, and also the many different approaches to morcellation. In addition, with the adaptation to contained morcellation, this review will cover research focused on optimizing a containment system and the techniques involved. SUMMARY: In summary, this review is aimed at describing many of the currently available power morcellation products and contained morcellation systems in an effort to allow physicians to understand the different options available, and to discuss well tolerated, effective, and clinically proven techniques that can lead to improved surgical outcomes in the future. PMID- 29194077 TI - Advances in targeting HER2-positive breast cancer. AB - PURPOSE OF REVIEW: Breast cancer is the most common malignancy in women and HER2 positive disease comprises about 15% of all breast cancer cases. Over the last few years, substantial advances have been made in treatment of early breast cancer (EBC) and advanced (ABC) HER2-positive (HER2+) breast cancer. The present review summarizes the major publications on HER2+ breast cancer in the year 2017 and discusses their clinical relevance. RECENT FINDINGS: The clinically most relevant data in 2017 relates to the EBC setting. The St. Gallen Consensus 2017 for the first time recommended neoadjuvant treatment as standard of care in HER2+ EBC. Moreover, the APHINITY trial demonstrated efficacy of adjuvant dual antibody based HER2 blockade. Data in MBC mostly confirmed established treatment strategies. SUMMARY: Clinical data presented in 2017 for HER2+ breast cancer confirmed current guidelines and extended treatment options for patients. First intriguing steps were made towards de-escalation in the EBC setting. PMID- 29194079 TI - Compliance With Best Practice Guidelines for Neurodevelopmental Supportive Care in South Africa: A Situational Analysis. AB - Neurodevelopmental supportive care provides preterm infants with evidence-based care to ensure the best possible neurological outcomes. The study aimed to determine the compliance of current nursing care practices with best practice guidelines by means of a situational analysis. The situational analysis was done in 2 cycles in the neonatal intensive care units (n = 25) of a private healthcare provider in South Africa. Structured observations were done in cycle 1 using the Implementation of Neurodevelopmental Supportive Care checklist. Cycle 2 comprised focus group discussions to verify findings from cycle 1. Seventeen conclusion statements were formulated, which were thematically combined to be presented as 9 categories: neonatal intensive care unit design, individualized care, family centered care, infant positioning, handling techniques, environmental manipulation, pain management, knowledge of infant behavior, and feeding. The conclusion statements identified improvement opportunities in current practice and offer suggestions, which can be used to guide an implementation strategy for best practice guidelines of neurodevelopmental supportive care in the neonatal intensive care units of the private healthcare group in future. Addressing improvement opportunities in all the categories will ensure that all aspects of the guideline requirements are met, resulting in a comprehensive strategy improving practice and patient outcomes. PMID- 29194078 TI - Stress From the Neonatal Intensive Care Unit to Home: Paternal and Maternal Cortisol Rhythms in Parents of Premature Infants. AB - To examine cortisol diurnal rhythms over the transition from the critical care setting to home for fathers and mothers of very low-birth-weight infants, including how cortisol is associated with psychosocial stress and parenting sense of competence. This cohort study in a level III neonatal intensive care unit and the general community had 86 parents complete salivary collection and self reported psychosocial measures. Salivary samples were collected 3 times a day on the day before discharge, and on 3 subsequent days at home. Self-report measures included the Perceived Stress Scale and the Parenting Sense of Competence Scale, which measure parenting satisfaction. Fathers showed increased physiologic stress over the transition home, reflected by flattening of slopes, lower wakeup, and higher bedtime cortisol. Mothers reporting increases in perceived stress over the transition home had higher bedtime cortisol, suggesting a link between higher perceived stress and higher physiologic stress. Results were significant after controlling for breastfeeding, insurance status, and gestational age. This study examined a physiologic marker of stress in parents with very low-birth-weight infants, finding sex disparities in diurnal cortisol patterns during the transition from neonatal intensive care unit to the community. Fathers may be especially susceptible to stressors during this transition. PMID- 29194080 TI - Temporal Fine Structure Processing, Pitch, and Speech Perception in Adult Cochlear Implant Recipients. AB - OBJECTIVES: The aim of the study was to investigate the link between temporal fine structure (TFS) processing, pitch, and speech perception performance in adult cochlear implant (CI) recipients, including bimodal listeners who may benefit better low-frequency (LF) temporal coding in the contralateral ear. DESIGN: The study participants were 43 adult CI recipients (23 unilateral, 6 bilateral, and 14 bimodal listeners). Two new LF pitch perception tests-harmonic intonation (HI) and disharmonic intonation (DI)-were used to evaluate TFS sensitivity. HI and DI were designed to estimate a difference limen for discrimination of tone changes based on harmonic or inharmonic pitch glides. Speech perception was assessed using the newly developed Italian Sentence Test with Adaptive Randomized Roving level (STARR) test where sentences relevant to everyday contexts were presented at low, medium, and high levels in a fluctuating background noise to estimate a speech reception threshold (SRT). RESULTS: Although TFS and STARR performances in the majority of CI recipients were much poorer than those of hearing people reported in the literature, a considerable intersubject variability was observed. For CI listeners, median just noticeable differences were 27.0 and 147.0 Hz for HI and DI, respectively. HI outcomes were significantly better than those for DI. Median STARR score was 14.8 dB. Better performers with speech reception thresholds less than 20 dB had a median score of 8.6 dB. A significant effect of age was observed for both HI/DI tests, suggesting that TFS sensitivity tended to worsen with increasing age. CI pure-tone thresholds and duration of profound deafness were significantly correlated with STARR performance. Bimodal users showed significantly better TFS and STARR performance for bimodal listening than for their CI-only condition. Median bimodal gains were 33.0 Hz for the HI test and 95.0 Hz for the DI test. DI outcomes in bimodal users revealed a significant correlation with unaided hearing thresholds for octave frequencies lower than 1000 Hz. Median STARR scores were 17.3 versus 8.1 dB for CI only and bimodal listening, respectively. STARR performance was significantly correlated with HI findings for CI listeners and with those of DI for bimodal listeners. CONCLUSIONS: LF pitch perception was found to be abnormal in the majority of adult CI recipients, confirming poor TFS processing of CIs. Similarly, the STARR findings reflected a common performance deterioration with the HI/DI tests, suggesting the cause probably being a lack of access to TFS information. Contralateral hearing aid users obtained a remarkable bimodal benefit for all tests. Such results highlighted the importance of TFS cues for challenging speech perception and the relevance to everyday listening conditions.

AB - OBJECTIVE: The objective of this study was to compare quantitative and qualitative RNA extraction results from clinical voided urine samples between 3 commercially available extraction protocols. METHODS: For phase 1, fresh voided urine samples from 10 female subjects were collected and processed in clinic and transported to the laboratory with cold packs. RNA was purified with 1 of 3 RNA extraction protocols: (1) TRI Reagent Protocol; (2) Absolutely RNA Nanoprep Kit; and (3) ZR Urine RNA Isolation Kit. Real-time polymerase chain reactions (RT-PCR) were performed. As the ZR Urine RNA Isolation Kit provided the highest quality RNA in phase 1, for phase 2, RNA was extracted from 9 additional voided urine specimens using this kit to perform additional qualitative analyses. RESULTS: Median RNA yield was significantly higher with the TRI Reagent Protocol as compared with the other protocols (P = 0.007). However, there was a significantly lower median threshold cycle value from polymerase chain reaction (indicating improved downstream application performance) with the ZR Urine RNA Isolation Kit as compared with the other methods (P = 0.005). In phase 2, the median RNA integrity number of urine RNA was 2.5 (range, 1.6-5.9). CONCLUSIONS: Although other methods may provide a higher quantity of RNA, when using clinical urine samples, the ZR Urine RNA Isolation Kit provided the highest quality of extracted RNA. This kit is especially attractive for the clinical setting because it does not require an initial centrifugation step. The urine RNA obtained with this kit may be useful for polymerase chain reaction but is not likely to be of high enough integrity for RNA sequencing.

PMID- 29194083 TI - Management of Reducible Ventral Hernias: Clinical Outcomes and Cost-effectiveness of Repair at Diagnosis Versus Watchful Waiting. AB - OBJECTIVE: To compare long-term clinical and economic outcomes associated with 3 management strategies for reducible ventral hernia: repair at diagnosis (open or laparoscopic) and watchful waiting. BACKGROUND: There is variability in ventral hernia management. Recent data suggest watchful waiting is safe; however, long term clinical and economic outcomes for different management strategies remain unknown. METHODS: We built a state-transition microsimulation model to forecast outcomes for individuals with reducible ventral hernia, simulating a cohort of 1 million individuals for each strategy. We derived cohort characteristics (mean age 58 years, 63% female), hospital costs, and perioperative mortality from the Nationwide Inpatient Sample (2003-2011), and additional probabilities, costs, and utilities from the literature. Outcomes included prevalence of any repair, emergent repair, and recurrence; lifetime costs; quality-adjusted life years (QALYs); and incremental cost-effectiveness ratios. We performed stochastic and probabilistic sensitivity analyses to identify parameter thresholds that affect optimal management, using a willingness-to-pay threshold of $50,000/QALY. RESULTS: With watchful waiting, 39% ultimately required repair (14% emergent) and 24% recurred. Seventy per cent recurred with repair at diagnosis. Laparoscopic repair at diagnosis was cost-effective compared with open repair at diagnosis (incremental cost-effectiveness ratio $27,700/QALY). The choice of operative strategy (open vs laparoscopic) was sensitive to cost and postoperative quality of life. When perioperative mortality exceeded 5.2% or yearly recurrence exceeded 19.2%, watchful waiting became preferred. CONCLUSIONS: Ventral hernia repair at diagnosis is very cost-effective. The choice between open and laparoscopic repair depends on surgical costs and postoperative quality of life. In patients with high risk of perioperative mortality or recurrence, watchful waiting is preferred.

METHODS: Exhaled breath samples were collected using 2-L double-layered Nalophan bags, and were analyzed using selected-ion-flow-tube mass-spectrometry. Gold-standard test for comparison was endoscopy for luminal inspection and computed tomography (CT) to confirm cancer recurrence. Three studies were conducted: RESULTS:: CONCLUSION:: This study suggests the association of a single breath biomarker with the primary presence and recurrence of CRCa.

AB - OBJECTIVE: The aim of this paper is to report, with a high follow-up rate, 10 year results in a large cohort of patients after Roux-en-Y gastric bypass (RYGBP) done essentially by laparoscopy. BACKGROUND: RYGBP has been performed for 50 years, including 20 years by laparoscopy, yet very few long-term results have been reported, mostly after open surgery. METHODS: Prospective bariatric database established since the introduction of bariatric surgery. Retrospective data analysis on weight loss, long-term complications, quality of life, and comorbidities. RESULTS: In all, 658 consecutive patients (515 women/143 men) were included: 554 with primary RYGBP, 104 with reoperative RYGBP. There was 1 (0.15%) postoperative death. Thirty-two (5%) patients died during follow-up from causes unrelated to surgery. Ten years after primary RYGBP, patients lost 28.6 +/- 10.5% of their initial weight, corresponding to a mean of 13.2 body mass index (BMI) units. Among them, 72.8% achieved a BMI <35. Weight loss >=20% was seen in 80.3% and <10% in 3.9% of patients. Results were similar in patients undergoing primary or reoperative RYGBP, but were better in patients who were initially less obese (BMI <50 kg/m) than in superobese patients. Quality of life and comorbidities significantly improved with 80% resolution or improvement of metabolic comorbidities. All patients required supplementations, and 14.6% required long term reoperation. CONCLUSIONS: RYGBP provides long-term satisfactory weight loss up to 10 years, and significantly improves quality of life and comorbidities. Long-term complications requiring reoperation can develop. Mineral and vitamin supplementation are universally necessary. Other more effective surgical options should be discussed in patients with very severe obesity.

PMID- 29194088 TI - The Range and Impact of Postmigration Stressors During Treatment of Trauma Affected Refugees. AB - Trauma-affected refugees commonly experience postmigration stressors, which can compound conflict-related emotional distress. Our study aimed to assess clinician rated frequency and types of postmigration stressors deemed to be interfering with the treatment of refugees attending a service for trauma-related mental distress. A total of 116 patients completed 6 months of multidisciplinary treatment. Clinician-rated postmigration stressors were registered at each session. Outcome measures were Harvard Trauma Questionnaire and Global Assessment of Functioning, function (GAF-F) and symptom. Postmigration stressors were deemed to impact on 39.1% of treatment sessions with medical personnel. Issues related to work, finances, and family were the most frequently identified stressors. Postmigration stressors interfering with treatment were more common among male refugees, those living alone, those from Middle Eastern origin, and persons with low baseline GAF-F. Explicitly identifying and, where possible, dealing with postmigration stressors may assist in averting their interference with the treatment of distress in refugees. PMID- 29194089 TI - Quetiapine Dose Adjustments in Pregnant and Postpartum Women With Bipolar Disorder. PMID- 29194091 TI - Menthol reduces phototoxicity pain in a mouse model of photodynamic therapy. AB - Phototoxicity-induced pain is a major clinical problem triggered by light acting on photosensitising drugs or endogenous porphyrins, notably protoporphyrin IX (PpIX), an intermediary in heme biosynthesis. Protoporphyrin IX accumulates in individuals with erythropoietic protoporphyria and is elevated during photodynamic therapy subsequent to application of 5-aminolevulinic acid (ALA). Pain occurs during irradiation of PpIX and responds poorly to conventional analgesics. Our objective was to develop a model of PpIX phototoxicity pain and investigate the potential of menthol as an analgesic. Application of ALA to the tails of C57 black and SWISS white mice caused PpIX accumulation and nociception during irradiation (630 nm at 3.7 J/cm). Despite similar PpIX accumulation, C57 mice exhibited less pain behavior compared with SWISS mice because of light absorption by pigmentation. Irradiation of ALA-treated dorsal root ganglion neurons caused phototoxicity-evoked action potentials (APs) in both mouse strains. The antioxidant L-tryptophan increased the light dose required to elicit such APs. By contrast, the addition of keratinocytes to neuronal cultures decreased the threshold for APs, suggesting a requirement for proliferating cells. Inhibition of fatty acid amide hydrolase, selective antagonism of TRPV1 or the application of lidocaine or its quaternary derivative QX-314, reduced AP frequency, whereas antagonism of TRPA1 had no effect. These results suggest that products of singlet oxygen-mediated lipid peroxidation trigger nociceptor activation via TRPV1. Menthol inhibited phototoxicity-evoked APs and reduced pain behavior when applied topically to mice. These findings suggest that menthol might provide pain relief in patients experiencing PpIX-phototoxicity pain caused by photodynamic therapy or erythropoietic protoporphyria. PMID- 29194090 TI - The association between uric acid levels and different clinical manifestations of coronary artery disease. AB - AIMS: Uric acid (UA) has been associated with the presence and severity of coronary artery disease. To further assess the role of UA role in coronary artery disease, we investigated UA levels in both healthy asymptomatic middle-aged individuals and in different subgroups of hospitalized patients with suspected or definite myocardial infarction (MI). PATIENTS AND METHODS: The severity of coronary artery calcification (CAC) was examined in asymptomatic individuals (n=1039) using a noncontrast computed tomography scan. Hospitalized patients with suspected acute MI (n=772) were grouped according to troponin I (TnI) concentrations: (i) elevated TnI concentrations (>0.03 ug/l) with subdivision according to the type of MI and other clinical conditions associated with myocardial injury, or (ii) nonelevated TnI concentrations (<=0.03 ug/l). RESULTS: UA was not associated with the severity of CAC in asymptomatic individuals when adjusting for relevant risk factors. Patients with type 2 MI and patients with myocardial injury associated with conditions of myocardial ischemia showed significantly higher UA levels (0.390 mmol/l, P=0.002 and 0.400 mmol/l, P=0.001, respectively) than patients with type 1 MI (0.329 mmol/l), after adjusting for other risk factors. CONCLUSION: UA was not correlated with the severity of CAC in asymptomatic middle-aged individuals, and patients with type 2 MI or ischemic myocardial injury were shown to have higher UA levels than type 1 MI patients. This observation is concordant with the hypothesis that UA might be involved in the pathophysiological mechanisms leading to an imbalance in the oxygen supply/demand ratio in type 2 MI and ischemic myocardial injury. PMID- 29194092 TI - Clinicopathologic Features and Prognostic Impact of Lymph Node Involvement in Patients With Breast Implant-associated Anaplastic Large Cell Lymphoma. AB - Breast implant-associated anaplastic large cell lymphoma (BI-ALCL) is a rare T cell lymphoma that arises around breast implants. Most patients manifest with periprosthetic effusion, whereas a subset of patients develops a tumor mass or lymph node involvement (LNI). The aim of this study is to describe the pathologic features of lymph nodes from patients with BI-ALCL and assess the prognostic impact of LNI. Clinical findings and histopathologic features of lymph nodes were assessed in 70 patients with BI-ALCL. LNI was defined by the histologic demonstration of ALCL in lymph nodes. Fourteen (20%) patients with BI-ALCL had LNI, all lymph nodes involved were regional, the most frequent were axillary (93%). The pattern of involvement was sinusoidal in 13 (92.9%) cases, often associated with perifollicular, interfollicular, and diffuse patterns. Two cases had Hodgkin-like patterns. The 5-year overall survival was 75% for patients with LNI and 97.9% for patients without LNI at presentation (P=0.003). Six of 49 (12.2%) of patients with tumor confined by the capsule had LNI, compared with LNI in 8/21 (38%) patients with tumor beyond the capsule. Most patients with LNI achieved complete remission after various therapeutic approaches. Two of 14 (14.3%) patients with LNI died of disease compared with 0/56 (0%) patients without LNI. Twenty percent of patients with BI-ALCL had LNI by lymphoma, most often in a sinusoidal pattern. We conclude that BI-ALCL beyond capsule is associated with a higher risk of LNI. Involvement of lymph nodes was associated with decreased overall survival. Misdiagnosis as Hodgkin lymphoma is a pitfall.

PMID- 29194093 TI - CDKN2A/B Deletion and Double-hit Mutations of the MAPK Pathway Underlie the Aggressive Behavior of Langerhans Cell Tumors. AB - Langerhans cell histiocytosis (LCH) has a mostly favorable outcome, whereas Langerhans cell sarcoma (LCS) is an aggressive tumor. It is still unclear whether any specific molecular alterations could underlie the aggressive behavior of Langerhans cell proliferations. We used targeted next-generation sequencing and array-comparative genomic hybridization to profile 22 LCH samples from different patients together with 3 LCS samples corresponding to different relapses from the same patient. The third LCS relapse was a composite tumor including both B-cell chronic lymphocytic leukemia and LCS components. The 22 LCH samples were mostly of bone origin and showed classic histophenotypical features. Array-comparative genomic hybridization showed in all 3 LCS samples a similar homozygous somatic loss affecting the CDKN2A/B locus, whereas the 17 informative LCH samples did not show any detectable abnormality. In the 3 LCS samples, targeted next-generation sequencing of 495 cancer genes detected common mutations in KMT2D/MLL2 and in both MAP2K1 and NRAS genes, whereas BRAF was not mutated. A NOTCH1 mutation was acquired in 2 LCS samples. The composite LCS/B-cell chronic lymphocytic leukemia tumor showed the same genetic profile in its 2 components. LCH samples showed mutually exclusive mutations of BRAF (8/20) and MAP2K1 (4/19), but no mutation of KMT2D, NRAS nor NOTCH1. These results suggest that CDKN2A/B deletion and/or simultaneous mutations of MAP2K1 and NRAS may underlie the aggressive behavior of Langerhans cell tumors, and thus could be useful for the diagnosis of malignancy in histiocytic neoplasms. The MAPK pathway "double hit" profile provides a basis for targeted therapy in LCS patients. PMID- 29194095 TI - Is nonmetastatic cutaneous melanoma predictable through genomic biomarkers? AB - Cutaneous melanoma is a highly aggressive skin cancer whose treatment and prognosis are critically affected by the presence of metastasis. In this study, we address the following issue: which gene transcripts and what kind of interactions between them can allow to predict nonmetastatic from metastatic melanomas with a high level of accuracy? We carry out a meta-analysis on the first gene expression set of the Leeds melanoma cohort, as made available online on 11 May 2016 through the ArrayExpress platform with MicroArray Gene Expression number 4725. According to the authors, primary melanoma mRNA expression was measured in 204 tumours using an illumina DASL HT12 4 whole-genome array. The tumour transcripts were selected through a recently proposed predictive-based regression algorithm for gene-network selection. A set of 64 equivalent models, each including only two gene transcripts, were each sufficient to accurately classify primary tumours into metastatic and nonmetastatic melanomas. The sensitivity and specificity of the genomic-based models were, respectively, 4% (95% confidence interval: 0.11-21.95%) and 99% (95% confidence interval: 96.96 99.99%). The very high specificity coupled with a significantly large positive likelihood ratio leads to a conclusive increase in the likelihood of disease when these biomarkers are present in the primary tumour. In conjunction with other highly sensitive methods, this approach can aspire to be part of the future standard diagnosis methods for the screening of metastatic cutaneous melanoma. The small dimension of the selected transcripts models enables easy handling of large-scale genomic testing procedures. Moreover, some of the selected transcripts have an understandable link with what is known about cutaneous melanoma oncogenesis, opening a window on the molecular pathways underlying the metastatic process of this disease. PMID- 29194097 TI - An Autologous Leukocyte-Reduced Platelet-Rich Plasma Therapy for Chronic Injury of the Medial Collateral Ligament in the Knee: A Report of 3 Successful Cases. AB - Some patients complain of chronic persistent medial knee pain after isolated low grade injuries of medial collateral ligaments (MCL). These injuries often respond to various conservative treatments but insufficient healing of ligaments is believed to be responsible for symptoms in this group of patients. We report on successful treatment of chronically symptomatic MCL injuries in 3 patients using autologous leukocyte-reduced platelet-rich plasma (PRP) injections. There were 3 men with a mean age of 39.3 years and a mean disease duration of 10 months. Magnetic resonance imaging showed discontinuities of superficial layers and thickness of deep layers in the proximal MCL. After PRP injections, all cases returned to their sport activities at a previous level as without symptoms, and complete healing of proximal ligaments was identified on magnetic resonance images. The outcomes indicated that PRP injections led to successful repair for chronic injuries of MCL in knees. PMID- 29194096 TI - The Interplay between Genes and Psychosocial Home Environment on Physical Activity. AB - INTRODUCTION: Genetic factors contribute to individual differences in physical activity, but it remains uncertain whether the magnitude of the genetic effects is modified by variations in home environments. We aimed to examine to what extent the psychosocial home environment in childhood and adolescence modifies the genetic influences on leisure time physical activity in young adulthood. METHODS: Participants were Finnish twins (N = 3305) who reported their leisure time physical activity at age 24 yr. The psychosocial home environment was assessed by twins at ages 12, 14, and 17 yr, as well as by their parents when the twins were age 12 yr. Gene-environment interaction modeling was performed with OpenMx software. RESULTS: Parental ratings of positive home atmosphere as well as the twins' ratings of both positive home atmosphere at age 14 yr and lower relational tensions at ages 12 and 14 yr predicted higher leisure time physical activity levels in young adulthood (regression coefficients = 0.33-0.64). Parental perceptions as well as the twins' perceptions of positive home atmosphere at ages 14 and 17 yr increased the additive genetic variation (moderation effects: 0.55, 95% confidence interval [CI] = 0.29-0.80; 0.60, 95% CI = 0.26-1.05; and 0.52, 95% CI = 0.19-0.87, respectively). The twins' ratings of positive home atmosphere at age 12 yr and lower relational tensions at ages 12 and 14 yr increased the unique environmental variation of their subsequent physical activity (moderation effects: 0.46, 95% CI = 0.19-0.60; 0.48, 95% CI = 0.29-0.64; and 0.85, 95% CI = 0.12-0.95, respectively). CONCLUSIONS: A psychosocial home environment that is warm and supportive in childhood and adolescence not only increases the mean level of subsequent leisure time physical activity in young adulthood but also modifies the genetic and environmental variances in leisure time physical activity.

AB - Totally endoscopic robotic surgery is a safe approach to atrial septal defect closure in adults. Robotic approach can be an alternative to traditional incisions in the management of concomitant tricuspid valve regurgitation with ruptured chordae tendineae. Herein, we describe a woman who presented with atrial septal defect and tricuspid insufficiency after an unsuccessful percutaneous intervention with device removal from the right ventricle. Concomitant closure of septal defect and tricuspid valve repair with artificial chords was successfully performed using robot assistance. PMID- 29194100 TI - Hematomas in Tiger Territory: An Endovascular Alternative to Wading In. AB - A 26-year-old man presented with gunshot wound to the epigastrium. At surgery, he was hemodynamically stable and had a tense hematoma with thrill in zone 2 (right side) and porta triad. After liver injury was controlled, he underwent percutaneous stenting of a renal artery-vena cava fistula and the hepatic artery injury was followed. Historically, penetrating injury to zone 2 has mandated operative exploration. However, with the advent of endovascular options, in stable patients, catheter-based options offer a reasonable alternative with less risk of blood loss and possible nephrectomy. Renal artery stenting has been advocated for renal artery cava fistulas. The role of timing, hybrid operating suites, and traditional operative exposure will vary based on presentation and institutional capabilities. PMID- 29194101 TI - Impact of an Ultrasonically Activated Device in Robot-Assisted Distal Gastrectomy. AB - OBJECTIVE: Robot-assisted gastrectomy is increasingly used for the treatment of gastric cancer, although it remains a time-consuming procedure. An ultrasonically activated device might be useful to shorten operation times. This study therefore assessed the effect of ultrasonically activated device use on procedural times and on other early surgical outcomes. METHODS: Consecutive patients (N = 42) who underwent robot-assisted distal gastrectomy for gastric cancer were included. Clinicopathological characteristics and early surgical outcomes were compared between robotic-assisted gastrectomy procedures using an ultrasonically activated device (U group, n = 21) and those without it (NU group, n = 21). RESULTS: There were no significant differences in patient characteristics between the groups; however, the median operation time was significantly less in the U group than in the NU group (291 vs 351 minutes, P = 0.006). In detail, the median duration of console time until dividing the duodenum was less in the U group (70 vs 102 minutes, P < 0.001). Estimated blood loss, incidence of postoperative morbidity, and duration of postoperative hospital stay were not different between the groups. CONCLUSIONS: An ultrasonically activated device reduced the operation time of robot-assisted gastrectomy without increasing blood loss and morbidity. PMID- 29194102 TI - Neurocognitive Profiling of Adult Treatment Seekers Enrolled in a Clinical Trial of a Web-delivered Intervention for Substance Use Disorders. AB - OBJECTIVE: This study is a secondary descriptive analysis that explores and compares the cognitive profiles of adults entering treatment at geographically diverse community-based substance use disorder treatment facilities. METHODS: Performance on cognitive measures at baseline was compared across 5 primary substance subgroups of individuals (alcohol = 104; cocaine = 102; stimulants = 69; opioids = 108; marijuana = 114) enrolled in a web-based psychosocial treatment study conducted within the National Drug Abuse Treatment Clinical Trials Network. MicroCog subtests were used to assess cognitive domains of attention and mental control, reasoning and cognitive flexibility, and spatial processing. RESULTS: The average age of onset for a substance use disorder was early to mid-20s, with marijuana users reporting the earliest age of onset (mean 19.9, SD 7.5) and stimulant users reporting the latest (mean 25.2, SD 9.9). Among the total sample, half (49.7%) demonstrated impairment in cognitive flexibility and reasoning, and over one-third (37.3%) had impairment in verbal learning and memory. Stimulant (37.68%) and cocaine (34.31%) users showed significantly greater clinical impairment in attention and mental control compared with alcohol users (17.31%) and opioid (21.30%) users (stimulant subgroup only) (chi [4] = 10.97, P = 0.027). Cocaine users showed the greatest overall impairment across total and proficiency subtest scores, although these were not statistically different from other subgroups. CONCLUSIONS: These findings confirmed previous studies, indicating a high prevalence of significant cognitive dysfunction across all substance use categories among treatment-seeking adults, and found that cocaine use appears to be associated with the most impairment. Increasing knowledge of similarities and differences between primary substance subgroups can help guide substance use disorder treatment planning. PMID- 29194103 TI - Concerns of Anophthalmic Patients Wearing Cryolite Glass Prosthetic Eyes. AB - PURPOSE: To identify the main concerns of patients experienced in wearing cryolite glass prosthetic eyes and to investigate how these have changed over time. METHODS: One hundred six patients experienced in wearing prosthetic eyes for at least 2 years were asked to complete an anonymous questionnaire regarding prosthetic eye concerns at the time of initial eye loss and at the present time. Main outcome measures included changes in levels of concern over time. RESULTS: Initially, the participants were mainly concerned about their appearance, health of the fellow eye, and coping with monocularity. Over time, there was a significant increase of the level of concern regarding the health of the remaining eye (p < 0.001) and regarding watering, crusting, and discharge (p < 0.001). Loss of balance did not change significantly (p = 0.302). All other concerns decreased significantly over time (p < 0.001), with levels of concern about appearance decreasing the most. The current leading concern was the health of the remaining eye followed by concerns about watering, crusting, and discharge. Length of time since natural eye loss was the most important explanatory variable, with significant impact on the concerns about appearance (p = 0.013), retention of the prosthetic eye (p = 0.002), and eyelid contour (p = 0.004). CONCLUSIONS: Health of the remaining eye is the most common current concern of anophthalmic patients, acknowledging the need of good ophthalmologic follow up after losing an eye. The second most important concern is with watering, crusting, and discharge, suggesting further research for establishing an evidence-based protocol for cryolite glass prosthetic eye maintenance and supportive treatment. PMID- 29194104 TI - Comparison of Outcomes of 3-Snip Punctoplasty Versus Simple Punctal Dilatation With Monocanalicular Intubation for Acquired Punctal Stenosis. AB - PURPOSE: To evaluate and compare the outcomes of invasive (rectangular 3-snip punctoplasty) versus minimally invasive (punctal dilatation with monocanalicular intubation) treatment modalities for the management of acquired punctal stenosis. METHODS: A retrospective, comparative, interventional case series was performed on 60 eyes of 36 patients with acquired punctal stenosis. Patients were categorized in 2 groups based on the intervention as 3-snip punctoplasty (group A) and punctal dilatation with monocanalicular intubation (group B). Qualitative and quantitative assessment for epiphora and punctal stenosis grading were performed preoperatively and postoperatively. Patients with associated canalicular and nasolacrimal duct obstructions, congenital punctal disorders, eyelid malpositions, and less than 6 months' follow up were excluded. Anatomical and functional successes were recorded following stent extubation and at 6-month follow up. Statistical analyses were performed using the chi-square, Fisher exact, and the Mann-Whitney tests. A p value of <0.05 was considered significant. RESULTS: Ninety-nine puncta of 62 eyes of 36 patients were analyzed. Mean age at presentation was 49 and 50 years in groups A and B, respectively. Bilaterality was noted in 67% (24/36) of the patients. Epiphora was the most common presentation. Involvement of upper punctum was noted in 6% (4/62), lower punctum in 34% (21/62), and both in 60% (35/62) of eyes. At 6-month follow up, the anatomical success rate was 84% (47 out of 56 puncta) in group A, whereas 93% (40 out of 43 puncta) in group B (p = 0.29). At 6-month follow up, restenosis occurred in more number of puncta (n = 9) in group A and only in 3 puncta in group B; however, this was not statistically significant (p = 0.21). No stent related complications were noted. CONCLUSION: Punctal dilatation with monocanalicular intubation achieves comparable outcomes as that of 3-snip punctoplasty in patients with acquired punctal stenosis. PMID- 29194105 TI - Immune Reconstitution Inflammatory Syndrome in a Case of Nonspecific Orbital Inflammation. AB - The immune reconstitution inflammatory syndrome is an exaggerated abnormal immune response, typically seen in HIV-positive patients following restoration of a normal CD4 count as a result of initiation of antiretroviral therapy. It has been described in relation to either occult opportunistic infections or to a paradoxical relapse of a previously successfully treated infection with negative microbiological cultures. The authors report the case of a 60-year-old HIV positive African male who presented with 2 episodes of orbital inflammation that occurred in conjunction with improvements of CD4 count following Highly Active Antiretroviral Therapy. This phenomenon was underpinned by biopsies obtained following each episode. Interestingly, on both occasions, he responded well to corticosteroid therapy. Although the soft tissues of the orbits are a common area affected by other inflammatory diseases, it is rare for them to be involved in immune reconstitution inflammatory syndrome. To the authors' knowledge, this is the first case report of immune reconstitution inflammatory syndrome affecting the orbits exclusively. The authors believe that it is probably an underdiagnosed condition and may be erroneously labeled as idiopathic in many cases. This case report inspires us to keep an open mind when dealing with patients on antiretroviral therapy. PMID- 29194106 TI - Increasing Authenticity of Simulation-Based Assessment in Diagnostic Radiology. AB - INTRODUCTION: Clinical reasoning in diagnostic imaging professions is a complex skill that requires processing of visual information and image manipulation skills. We developed a digital simulation-based test method to increase authenticity of image interpretation skill assessment. METHODS: A digital application, allowing volumetric image viewing and manipulation, was used for three test administrations of the national Dutch Radiology Progress Test for residents. This study describes the development and implementation process in three phases. To assess authenticity of the digital tests, perceived image quality and correspondence to clinical practice were evaluated and compared with previous paper-based tests (PTs). Quantitative and qualitative evaluation results were used to improve subsequent tests. RESULTS: Authenticity of the first digital test was not rated higher than the PTs. Test characteristics and environmental conditions, such as image manipulation options and ambient lighting, were optimized based on participants' comments. After adjustments in the third digital test, participants favored the image quality and clinical correspondence of the digital image questions over paper-based image questions. CONCLUSIONS: Digital simulations can increase authenticity of diagnostic radiology assessments compared with paper-based testing. However, authenticity does not necessarily increase with higher fidelity. It can be challenging to simulate the image interpretation task of clinical practice in a large-scale assessment setting, because of technological limitations. Optimizing image manipulation options, the level of ambient light, time limits, and question types can help improve authenticity of simulation-based radiology assessments. PMID- 29194107 TI - Vestibulovaginal Sclerosis Versus Lichen Sclerosus. AB - To determine if vestibulovaginal sclerosis and lichen sclerosus (LS) are 2 distinct entities. Biopsies obtained from the vagina or vulvar vestibule that contained abnormal subepithelial collagen were reviewed. Cases were categorized either as LS or vestibulovaginal sclerosis based on presence or absence of basal layer degeneration and lymphocytic infiltrate. Clinical data collected included examination findings, biopsy site and indication, previous vulvovaginal surgery, medications at time of biopsy, vulvar LS, treatment, and response. There were 15 cases with a mean age of 62 yr (range: 32-86 yr); 12 (80%) specimens were from vestibule and 3 from vagina. Nine cases were categorized as LS because of lymphocytic infiltrate in combination with basal layer degeneration, of these 8 had LS elsewhere on vulvar skin. Six cases were classified as vestibulovaginal sclerosis and had an absent or sparse lymphocytic infiltrate and essentially normal epithelium; none of these had vulvar LS. While vestibulovaginal sclerosis and lichen sclerosus are distinguishable clinically and histopathologically, further studies are needed to determine if vestibulovaginal sclerosis is a subset of LS or a different condition. PMID- 29194109 TI - Crystalline arthropathy and bone health. AB - PURPOSE OF REVIEW: The purpose of this review is to provide insight on the proposed association between crystal arthritis and bone health. Crystal arthritis is the most common type of inflammatory arthritis, and fractures contribute to significant morbidity and mortality, therefore, the relationship between the two is of clinical importance. RECENT FINDINGS: There have been variable findings regarding hyperuricemia, low bone density and risk of fracture. A recent systematic review and meta-analysis of available literature showed a correlation between increased serum uric acid and lower risk of fracture. Less is known about calcium pyrophosphate deposition disease and bone health, although two large studies have suggested an association with osteopenia. SUMMARY: A systematic review and meta-analysis of available data suggest a correlation between increased serum uric acid and lower risk of fracture. Findings support an association between bone health and crystal arthritis which warrants further study and may have implications for how we treat gout.

AB - PURPOSE OF REVIEW: Aberrant epigenetic changes in DNA methylation, histone marks, and noncoding RNA expression regulate the pathogenesis of many rheumatic diseases. The present article will review the recent advances in the epigenetic profile of inflammatory arthritis and discuss diagnostic biomarkers and potential therapeutic targets. RECENT FINDINGS: Methylation signatures of fibroblast-like synoviocytes not only distinguish rheumatoid arthritis (RA) and osteoarthritis (OA), but also early RA from late RA or juvenile idiopathic arthritis. Methylation patterns are also specific to individual joint locations, which might explain the distribution of joint involvement in some rheumatic diseases. Hypomethylation in systemic lupus erythematosus (SLE) T cells is, in part, because of active demethylation and 5-hydroxymethylation. The methylation status of some genes in SLE is associated with disease severity and has potential as a diagnostic marker. An integrative analysis of OA methylome, transcriptome, and proteome in chondrocytes has identified multiple-evidence genes that might be evaluated for therapeutic potential. Class-specific histone deacetylase inhibitors are being evaluated for therapy in inflammatory arthritis. SUMMARY: Disease pathogenesis is regulated by the interplay of genetics, environment, and epigenetics. Understanding how these mechanisms regulate cell function in health and disease has implications for individualized therapy. PMID- 29194110 TI - One-Year Retention Study of Adjunctive Perampanel Treatment in Epilepsy Patients. AB - OBJECTIVES: Perampanel is a recently introduced antiepileptic drug (AED) with a unique action mechanism of noncompetitive and selective alpha-amino-3-hydroxy-5 methyl-4-isoxazolepropionic acid antagonist. Because of delayed approval of perampanel in most Asian countries, there is limited information on the clinical usefulness of perampanel in the Asian population. We performed a retrospective analysis of retention rate, seizure outcome, and adverse events for perampanel treatment in South Korea. METHODS: This was a retrospective, single-center, 1 year observational study. A total of 137 epilepsy patients (86 men, 51 women; age, 17-86 years) who were treated with perampanel as an adjunctive treatment were included. Perampanel was administered at a starting dose of 2 mg/d, and optimal-dose adjustments were made according to individual clinical responses. Efficacy and tolerability were analyzed during a 1-year follow-up. RESULTS: The overall retention rate was 71.3% at the 6-month follow-up and 61.0% at the 1-year follow-up. Retention rates were similar between patients with 1 concomitant AED and those taking 2 or more concomitant AEDs. The most common adverse event was somnolence, followed by dullness and psychiatric reactions, and the presence of psychiatric comorbidity was significantly associated with the development of psychiatric adverse reactions. CONCLUSIONS: We showed that the retention rate and adverse events for adjunctive perampanel treatment in the Korean population were comparable with those in Western countries. Our study also suggests that adjuvant perampanel treatment may be effective in patients taking a higher number of concomitant AEDs and that psychiatric comorbidity may be a risk factor for perampanel-induced psychiatric reactions.

PMID- 29194112 TI - Drug-Associated Spontaneous Orgasm: A Case Report and Systematic Review of Literature. AB - OBJECTIVES: Spontaneous orgasm is characterized by a spontaneous onset of orgasm without any preceding sexual or nonsexual trigger. It sheds insight on the mechanisms underlying orgasms and the sexual response cycle in humans. METHODS: We report a male patient of repetitive spontaneous orgasm under trazodone treatment and systematically review the literature on drug-associated spontaneous orgasm (DASO). RESULTS: A total of 25 patients (18 women and 7 men), including our reported case, experienced 27 DASO events. Over half of them were under 50 years of age during the DASO event. Depression was the leading morbidity for these patients, and a limited list of antidepressants and antipsychotics were involved in 92.5% of all DASO events. Although offending drugs possess variable pharmacological properties, their common effect is an augmentation of serotonin 1A (5HT1A) neurotransmission. Offending drugs seemingly increase personal susceptibility to DASO. Over half of the patients, especially men, did not concurrently experience sexual arousal or desire during the DASO event. In the remaining patients, the orgasm was accompanied by or ensued with arousal or desire. A reduction of dose or discontinuation of the offending drug usually abolished DASO. CONCLUSIONS: It appears that 5HT1A has a key role in generating orgasm. Orgasms may be activated through arousal-independent or arousal-dependent pathways, and both orgasms and sexual arousal are bidirectionally activated. This double-bidirectional model of sexual response cycle may promote the success of sexual procreation and recreation, and further research on this pathway could offer an innovative method to manage anorgasmia in the future. PMID- 29194113 TI - Anger Assessment in Patients Treated With Brivaracetam. AB - OBJECTIVES: To assess state and trait anger, adjusted by epilepsy type, seizure control, anxiety-depression status and quality of life, in patients treated with brivaracetam (BRV) from an open study. METHODS: We evaluated prospectively consecutive patients with partial onset seizures in an open-label study. Patients had 5 years or longer of epilepsy and were taking between 1 and 3 antiepileptic drugs. They were treated with BRV and compared with a control group selected from outpatients attending our epilepsy unit who met the following criteria: age >=16 years and diagnosis of epilepsy with focal-onset seizures at least 1 year before inclusion in the study. The following tests were assessed: State-Trait Anger with the Expression Inventory-2, Hospital Anxiety and Depression Scale, and Quality of Life in Epilepsy Inventory. RESULTS: We recruited 39 patients, 17 treated with BRV and 22 with other drugs, including 13 with levetiracetam (LEV). Mean age was 47.3 years, 43.6% were men. Symptomatic cases, 66% and 52% temporal lobe epilepsy. Antiepileptic drug polytherapy was present in 82.1% of the cases (100% BRV vs 68.2% control group). Demographic and clinical characteristics, as well as Quality of Life in Epilepsy Inventory and Hospital Anxiety and Depression Scale scores were similar in both groups. When compared with the subgroup of LEV groups did not differ significantly on their Hospital Anxiety and Depression Scale scores. CONCLUSIONS: This small, open study suggests that BRV increases anger measures less than LEV in epilepsy patients. However, larger, blinded control studies are required to establish whether this apparent difference can be confirmed. PMID- 29194114 TI - HIV-1 and hepatitis C virus selection bottleneck in Chinese people who inject drugs. AB - OBJECTIVES: For both HIV-1 and hepatitis C virus (HCV), assessing the stringency of the transmission process is a scientific priority. Enumerations of transmitted/founder (TF) viruses have shown a strict transmission bottleneck in sexual transmission of HIV-1 and a wide range in the multiplicity of infection in HCV. Here, we aim to determine the stringency of parenteral transmission for HIV 1 and HCV in people who inject drugs (PWID). DESIGN: We used molecular sequencing and several complementary analyses to enumerate the TF HIV-1 and HCV variants in a well described cohort of PWID in Xinjiang, China. METHODS: We performed single genome sequencing of HIV-1 env and 5' half HCV genomes, then applied phylogenetic analysis and validated models of early virus diversification to enumerate TF viruses in 60 PWID. We used multivariate analysis to determine correlates of multivariant transmission (MVT). RESULTS: We generated 1070 env region sequences from 33 HIV-1 early infected individuals and 773 5' half region sequences from 27 HCV early infected individuals. We found rates of MVT of 39 and 54%, respectively, for HIV-1 and HCV, with a limited range in the number of TF viruses in both infections. Behavioural characteristics suggested high-risk injection practices and lower risk sexual practices; we did not find an association between any specific behaviours and MVT. CONCLUSION: MVT is frequent in parenteral transmission of both HIV-1 and HCV in Xinjiang PWID, indicating a less stringent transmission process than sexual transmission. PMID- 29194115 TI - The validity of self-reported antiretroviral use in persons living with HIV: a population-based study. AB - OBJECTIVE: To assess the validity of self-reported antiretroviral therapy use (ART) using population-based cohort data. METHODS: Self-reported ART use and nonuse was compared with a validated laboratory assay in 557 HIV-positive participants in the Rakai Community Cohort Study surveyed between September and December 2011 in Rakai, Uganda. The study population included participants from seven communities, including one fishing community with high HIV prevalence (~41%). ART use was assayed using liquid chromatography-tandem mass spectrometry, which detects 20 antiretroviral drugs. HIV viral load measurements were also obtained. Individuals with at least two antiretroviral drugs detected were considered to be using ART. RESULTS: One hundred and fifty-three (27%) participants self-reported ART use of whom 148 (97%) had at least two antiretroviral drugs detected. There were at least two antiretroviral drugs detected in 11% (n = 44/404) of individuals with no self-reported ART use. Overall, the specificity of self-reported ART use was 99% (95% CI 97-100%) and the sensitivity was 77% (70-83%). Positive and negative predictive values were 97% (95% CI 93-99%) and 89% (95% CI 86-92%), respectively. Nondisclosure of ART use was significantly more common in younger persons (<30 years) and among those in trading occupations. CONCLUSION: Self-reported ART use has high specificity and moderate sensitivity providing reasonable, but conservative estimates of population-based ART use. There is more under-reporting of ART use among younger persons and traders suggesting a need for more research on barriers to self reporting of ART use in these sub-groups. PMID- 29194116 TI - Preexposure prophylaxis guidelines have low sensitivity for identifying seroconverters in a sample of young Black MSM in Chicago. AB - BACKGROUND: Identification of clients at greatest risk of acquiring HIV is critical for preexposure prophylaxi (PrEP) implementation. Young black MSM (YBMSM) have high incidence of HIV. We examined published guidelines in identifying eligible PrEP candidates, including seroconverters, in a representative cohort of YBMSM. METHODS: The uConnect cohort included YBMSM aged 16-29 years during PrEP roll-out in Chicago from 2013 and 2016. YBMSM with indications for PrEP were determined using Center for Disease Control and Prevention (CDC) guidelines, the HIV incidence risk index for MSM (HIRI-MSM) scoring tool, and Gilead recommendations with calculation of sensitivities, specificities, and area under the curve (AUC) for HIV seroconversion over 18 months. Incidence rate ratios (IRRs) using Poisson regression were modeled to compare individual and network factors associated with seroconversion. RESULTS: In the study cohort, 300 HIV uninfected YBMSM contributed 390.4 person-years of follow-up [mean age (SD), 22.3 years (3.07)]. HIV incidence was 8.5 cases per 100 person-years (95% confidence interval, 6.0-11.9). One network factor was associated with seroconversion: having partners more than 10 years older (IRR = 4.4, 95% confidence interval, 1.6-11.8). Overall, 49% of the cohort had an indication for PrEP using CDC guidelines; 72% using HIRI-MSM, and 86% using Gilead recommendations. HIV seroconverters (n = 33) were identified as PrEP eligible prior to seroconversion with sensitivities/AUCs for CDC (52%/0.51), HIRI MSM (85%/0.57), and Gilead guidelines (94%/0.54). CONCLUSION: Low sensitivity of CDC guidelines and limited AUC of HIRI-MSM and Gilead screening tools are of concern for PrEP implementation among most at risk populations such as YBMSM. Consideration of demographics, local epidemiology, and network factors may better guide identification of clients who could benefit most from PrEP. PMID- 29194117 TI - Nonsmall cell lung cancer from HIV-infected patients expressed programmed cell death-ligand 1 with marked inflammatory infiltrates. AB - OBJECTIVE: Immunotherapies targeting the programmed cell death-1 (PD-1)/PD-ligand 1 (PD-L1) checkpoint improved prognosis in lung cancer. PD-1/PD-L1 status, however, has not been investigated in human immunodeficiency virus (HIV)-positive patients. This study assessed PD-L1 status and tumor immune-cell infiltration in nonsmall cell lung cancer (NSCLC) in HIV patients. METHODS: Consecutive HIV patients treated between 1996 and 2014 were enrolled. PD-L1 tumor expression was assessed using immunohistochemistry with two antibodies (clones 5H1 and E1L3N), and tumor immune-cell infiltration with CD3, CD4, CD8, CD20, CD163, and MPO. PD L1 expression and immune infiltration results were compared with those of 54 NSCLCs from unknown HIV status patients. RESULTS: Thirty-four HIV-positive patients were evaluated: predominantly men (88.2%) (median age: 51.1 years) presenting stage IV (38.2%) adenocarcinomas (76.5%). The median blood CD4 count was 480 cells/MUL (86-1120) and 64% exhibited undetectable viral load. The PD-L1 score (percentage of positive cells * intensity) was higher in HIV-positive than HIV-undetermined patients with the E1L3N clone [median (range) 0 (0-150) versus 0 (0-26.7), P = 0.047], yet not with the 5H1 clone [0 (0-120) versus 0 (0-26.7) P = 0.07, respectively]. PD-L1 expression frequency did not differ between both cohorts (18.7 versus 9.3% using E1L3N and 10 versus 5.6% using 5H1 clone, respectively). There were significantly greater cytotoxic T-cell (P < 0.001), B lymphocyte (P = 0.005), and activated macrophage (P < 0.001) infiltrations in the HIV-positive patients, but no differences for CD4 T cells. CONCLUSION: Tumors in HIV-positive patients seem to express higher PD-L1 levels with increased immune infiltration, supporting their inclusion in clinical trials assessing immune checkpoint inhibitors. PMID- 29194118 TI - Trends in antiretroviral therapy prescription, durability and modification: new drugs, more changes, but less failure. AB - OBJECTIVE: To evaluate the real world durability of contemporary ART for treatment-naive people living with HIV (PLWH). DESIGN: A retrospective follow-up study in a multisite cohort. METHODS: This study of the CNICS (CFAR Network of Integrated Clinical Systems) cohort integrates data from eight Center for AIDS Research (CFARs). PLWH initiating ART between 2007 and 2014 were included. Durability was defined as time from the initiation until discontinuation/modification using Kaplan-Meier survival curves. Cox Proportional Hazards measured associations with various sociodemographic and clinical characteristics. RESULTS: Among 5373 PLWH, the initial regimen was modified in 2285 (43%) patients. Efavirenz/emtricitabine/tenofovir (n = 2173, 40%) was the most commonly prescribed initial ART regimen; elvitegravir/cobicistat/emtricitabine/tenofovir became more common after 2012. Median durability for all regimens was 48.6 months. There were statistically significant differences in median durability for NNRTI, InSTI, and protease inhibitor-based regimens, which lasted 61, 44, and 32 months, respectively. Female sex (aHR = 1.4; 95% CI 1.2-1.6), intravenous drug use (aHR = 1.6; 95% CI 1.3-1.9), and CD4 cell count less than 200 cells/MUl (aHR = 1.2; 95% CI 1.1-1.3) were significantly associated with regimen modification. Compared with InSTI, those receiving an InSTI/protease inhibitor (aHR = 2.7; 95% CI 2.0-3.7) or protease inhibitor-based ART (aHR = 1.9; 95% CI 1.6-2.2) were significantly more likely to be modified; but those receiving NNRTI (aHR = 1.1; 95% CI 0.9-1.3) were not. CONCLUSION: In treatment-naive PLWH, NNRTI and InSTI-based ART were most durable, relative to protease inhibitor and InSTI/protease inhibitor-based ART, and were least likely to be modified/discontinued. A greater understanding of reasons for regimen modification/discontinuation is needed to analyze contemporary regimen durability. PMID- 29194119 TI - Pulmonary disease in HIV-infected adults in the era of antiretroviral therapy. AB - : HIV in the antiretroviral therapy era is characterized by multimorbidity and the frequent occurrence of HIV-associated non-AIDS chronic health conditions. Respiratory symptoms and chronic pulmonary diseases, including chronic obstructive pulmonary disease, asthma, and cardiopulmonary dysfunction, are among the conditions that may present in persons living with HIV. Tobacco smoking, which is disproportionately high among persons living HIV, strongly contributes to the risk of pulmonary disease. Additionally, features associated with and at times unique to HIV, including persistent inflammation, immune cell activation, oxidative stress, and dysbiosis, may also contribute. This review summarizes the available literature regarding epidemiology of and risk factors for respiratory symptoms and chronic pulmonary disease in the current era. PMID- 29194120 TI - Experiences using and organizing HIV self-testing. AB - OBJECTIVE: HIV self-testing (HIVST) is now officially recommended by the WHO, yet much of HIVST evidence to date has focused on quantitative data and hypothetical concerns. Effective scale-up of HIVST in diverse local contexts requires qualitative data from experiences using and organizing HIVST. This qualitative systematic review aims to appraise and synthesize research evidence on experiences using and organizing HIVST. METHODS: We conducted a systematic search of seven primary literature databases, four gray literature sources, and reference lists reporting qualitative evidence on HIVST. Data extraction and thematic analysis were used to synthesize findings. Quality of studies was assessed using the Critical Appraisal Skills Programme tool. Confidence in review findings was evaluated using the Confidence in the Evidence from Reviews of Qualitative Research approach. The review protocol was registered (CRD42015027607). RESULTS: From 1266 potential articles, we included 18. Four studies were conducted in low-income countries, three in middle-income countries, 10 in high-income countries, and one in multiple countries. Generally, HIVST increased capacity to reach priority populations and expanded opportunities for service delivery. Self-testing was preferred to facility-based testing due to increased convenience and confidentiality, especially among stigmatized populations. HIVST decreased test-associated stigma compared with facility-based testing. HIVST generally empowered people because it provided greater control over individual testing needs. At the same time, HIVST rarely allowed husbands to coerce their wives to test. CONCLUSIONS: This review suggests that HIVST should be offered as an additional HIV testing option to expand testing and empower testers. Adapting national policies to incorporate HIVST will be necessary to guide scale-up. PMID- 29194121 TI - HIV-infected cannabis users have lower circulating CD16+ monocytes and IFN-gamma inducible protein 10 levels compared with nonusing HIV patients. AB - OBJECTIVE: Chronic immune activation and elevated numbers of circulating activated monocytes (CD16) are implicated in HIV-associated neuroinflammation. The objective was to compare the level of circulating CD16 monocytes and IFN gamma-inducible protein 10 (IP-10) between HIV-infected cannabis users (HIV+MJ+) and noncannabis users (HIV+MJ-) and determine whether in-vitro Delta Tetrahydrocannabinol (THC), a constituent of cannabis, affected CD16 expression as well as IP-10 production by monocytes. DESIGN: The levels of circulating CD16 monocytes and IP-10 from HIV+MJ- and HIV+MJ+ donors were examined. In-vitro experimentation using THC was performed on primary leukocytes isolated from HIV MJ-, HIV+MJ- and HIV+MJ+ donors to determine if THC has an impact on CD16 monocyte and IP-10 levels. METHODS: Flow cytometry was used to measure the number of blood CD16 monocytes and plasma IP-10 from HIV+MJ- and HIV+MJ+ donors. Peripheral blood mononuclear cells were isolated from HIV-MJ- and HIV+ (MJ- and MJ+) donors for in-vitro THC and IFNalpha treatment, and CD16 monocytes and supernatant IP-10 were quantified. RESULTS: HIV+MJ+ donors possessed a lower level of circulating CD16 monocytes and plasma IP-10, compared with HIV+MJ- donors. Further, monocytes from HIV+MJ+ donors were unable to induce CD16 expression when treated with in-vitro IFNalpha, whereas HIV-MJ- and HIV+MJ- donors displayed pronounced CD16 induction, suggesting anti-inflammatory effects by cannabis. Lastly, in-vitro THC treatment impaired CD16 monocyte transition to CD16 and monocyte-derived IP-10. CONCLUSION: Components of cannabis, including THC, may decelerate peripheral monocyte processes that are implicated in HIV associated neuroinflammation. PMID- 29194123 TI - Anti-HIV-1 antibody-dependent cellular cytotoxicity: is there more to antibodies than neutralization? AB - PURPOSE OF REVIEW: An increasing body of evidence suggests that nonneutralizing Fc effector functions including antibody-dependent cellular cytotoxicity (ADCC) contribute to protection against HIV-1 acquisition. We discuss recent advances in anti-HIV-1 ADCC research with a particular focus on ADCC mediated by Env-specific antibodies in vitro and in vivo, the curative potential of HIV-1-specific ADCC antibodies and the mechanisms of HIV-1 resistance to ADCC. RECENT FINDINGS: ADCC activities of broadly neutralizing and nonneutralizing monoclonal antibody panels were recently characterized in vitro against several lab-adapted and primary isolates of HIV-1. ADCC activity of these monoclonal antibodies generally correlated with binding to infected cells and were greater against the lab adapted strains compared with primary HIV-1 isolates. Several recent studies in mouse and macaque models of HIV-1 infection suggest Fc-mediated effector functions contribute to the protective efficacy of broadly neutralizing antibodies and exert immune pressure on HIV-1 in vivo. SUMMARY: An increasing body of evidence suggests that ADCC-mediating antibodies, particularly when combined with neutralizing functions, can facilitate prevention and control of HIV-1. The precise mechanisms of partial protection conferred by nonneutralizing antibodies in vivo remain unclear and will need to be fully investigated in order to realize their full potential for HIV-1 vaccines. PMID- 29194122 TI - Improving postpartum retention in care for women living with HIV in the United States. AB - : Research findings have consistently demonstrated that women living with HIV in the United States and globally experience declines in medication adherence and retention in care after giving birth. A number of studies have identified factors associated with postpartum retention in care, but the evidence base for interventions to address the problem and close this gap in the HIV care continuum is limited. Furthermore, the majority of studies have been conducted in low resource or moderate-resource countries and may be less applicable or require adaptation for use in high resource countries. In the United States, up to two thirds of women drop out of care after delivery and are unable to maintain or achieve viral suppression postpartum, at a time when maternal and pediatric health are closely linked. We conducted a critical review of the literature to identify existing gaps regarding maternal retention in the United States and conceptualize the problem through the lens of the integrated and ecological models of health behavior. This review describes existing barriers and facilitators to retention in HIV care postpartum from published studies and suggests steps that can be taken, using a multilevel approach, to improve maternal retention. We propose five core action steps related to increasing awareness of the problem of poor postpartum retention, addressing needs for improved care coordination and case management, and using novel approaches to adapt and implement peer support and technology-based interventions to improve postpartum retention and clinical outcomes of women living with HIV. PMID- 29194124 TI - Humanized mouse models to study pathophysiology and treatment of HIV infection. AB - PURPOSE OF REVIEW: Immunodeficient mice that lack all lymphocyte subsets and have phagocytic cells that are tolerant of human cells can be stably xenografted with human hematopoietic stem cell as well as other human tissues (fetal liver and thymus) creating 'human immune system' (HIS) mice. HIS mice develop all major human lymphocyte classes (B, T, natural killer, and innate lymphoid cell) and their specialized subsets as well as a variety of myeloid cells (dendritic cell, monocytes, and macrophages) thereby providing a small animal model in which to interrogate human immune responses to infection. RECENT FINDINGS: HIS mouse models have been successfully used to study several aspects of HIV-1 biology, including viral life cycle (entry, restriction, replication, and spread) as well as virus-induced immunopathology (CD4 T-cell depletion, immune activation, and mucosal inflammation). Recent work has shown that HIV reservoirs can be established in HIV-infected HIS mice after treatment with combinations of antiretroviral drugs thereby providing a model to test new approaches to eliminate latently infected cells. SUMMARY: HIS mice provide cost-effective preclinical platform to assess combination immunotherapies that can target HIV reservoirs. Therapeutic strategies validated in HIS mice should be considered in designing the roadmap toward HIV 'cure'. PMID- 29194125 TI - NaV1.7 and pain: contribution of peripheral nerves. AB - The sodium channel NaV1.7 contributes to action potential (AP) generation and propagation. Loss-of-function mutations in patients lead to congenital indifference to pain, though it remains unclear where on the way from sensory terminals to central nervous system the signalling is disrupted. We confirm that conditional deletion of NaV1.7 in advillin-expressing sensory neurons leads to impaired heat and mechanical nociception in behavioural tests. With single-fiber recordings from isolated skin, we found (1) a significantly lower prevalence of heat responsiveness to normally mechanosensitive C-fibers, although (2) the rare heat responses seemed quite vigorous, and (3) heat-induced calcitonin gene related peptide release was normal. In biophysical respects, although electrical excitability, rheobase, and chronaxy were normal, (4) axonal conduction velocity was 20% slower than in congenic wild-type mice (5) and when challenged with double pulses (<100 milliseconds interval), the second AP showed more pronounced latency increase (6). On prolonged electrical stimulation at 2 Hz, (7) activity dependent slowing of nerve fiber conduction was markedly less, and (8) was less likely to result in conduction failure of the mutant single fibers. Finally, recording of compound APs from the whole saphenous nerve confirmed slower conduction and less activity-dependent slowing as well as the functional absence of a large subpopulation of C-fibers (9) in conditional NaV1.7 knockouts. In conclusion, the clear deficits in somatic primary afferent functions shown in our study may be complemented by previously reported synaptic dysfunction and opioidergic inhibition, together accounting for the complete insensitivity to pain in the human mutants lacking NaV1.7.

PMID- 29194127 TI - Core outcome measurement instruments for clinical trials in nonspecific low back pain. AB - To standardize outcome reporting in clinical trials of patients with nonspecific low back pain, an international multidisciplinary panel recommended physical functioning, pain intensity, and health-related quality of life (HRQoL) as core outcome domains. Given the lack of a consensus on measurement instruments for these 3 domains in patients with low back pain, this study aimed to generate such consensus. The measurement properties of 17 patient-reported outcome measures for physical functioning, 3 for pain intensity, and 5 for HRQoL were appraised in 3 systematic reviews following the COSMIN methodology. Researchers, clinicians, and patients (n = 207) were invited in a 2-round Delphi survey to generate consensus (>=67% agreement among participants) on which instruments to endorse. Response rates were 44% and 41%, respectively. In round 1, consensus was achieved on the Oswestry Disability Index version 2.1a for physical functioning (78% agreement) and the Numeric Rating Scale (NRS) for pain intensity (75% agreement). No consensus was achieved on any HRQoL instrument, although the Short Form 12 (SF12) approached the consensus threshold (64% agreement). In round 2, a consensus was reached on an NRS version with a 1-week recall period (96% agreement). Various participants requested 1 free-to-use instrument per domain. Considering all issues together, recommendations on core instruments were formulated: Oswestry Disability Index version 2.1a or 24-item Roland-Morris Disability Questionnaire for physical functioning, NRS for pain intensity, and SF12 or 10-item PROMIS Global Health form for HRQoL. Further studies need to fill the evidence gaps on the measurement properties of these and other instruments. PMID- 29194130 TI - Competencies for Leaders in Nursing Education. AB - AIM: The study purpose was to identify and describe the competencies that educators need to be leaders in nursing education. BACKGROUND: Leadership is inherent within the role of the nurse educator; however, many lack formal education in leadership and are underprepared to fully embrace the faculty leadership role. there exists a dearth of research on the competencies necessary for leaders in nursing education. METHOD: Fifteen leaders in nursing education were interviewed. Data were analyzed using an inductive iterative process. trustworthiness was established. FINDINGS: Four competencies emerged: articulate and promote a vision for nursing education, function as a steward for the organization and nursing education, embrace professional values in the context of higher education, develop and nurture relationships. CONCLUSION: Leadership is an essential component of the nurse educator role. The findings provide evidence to support best practices in nursing education and to advance the science of nursing education. PMID- 29194131 TI - Narrative Pedagogy: Transforming Nursing Education Through 15 Years of Research in Nursing Education. AB - AIM: This article provides a review of current disciplinary understanding of Narrative Pedagogy and describes the implications for ongoing transformation in nursing education. BACKGROUND: Narrative Pedagogy has been enacted and investigated by teachers around the world for more than 15 years. Few nursing educational innovations or pedagogies in nursing have been adopted in such an array of settings/levels. METHOD: A review of the nursing literature was conducted to locate reports of research on and teaching innovations derived from Narrative Pedagogy. RESULTS: Narrative Pedagogy has an extensive and longitudinal body of research describing how the approach contributes to the educational transformation the discipline seeks. CONCLUSION: Narrative Pedagogy and the growing literature describing how it is enacted provides a way for teachers and students to persist in questioning their current understanding of nursing, the ways they think about the situations they encounter, and how their practice can best be learned. PMID- 29194132 TI - Reflections of Evidence-Based Practice in Nurse Educators' Teaching Philosophy Statements. AB - AIM: This article focuses on the nature and importance of evidence-based practice (EBP) as described in the teaching philosophy statements of academic nurse educators (ANEs). BACKGROUND: EBP is a core competency identified by the Institute of Medicine. Its incorporation into teaching philosophies expresses ANEs' ideas, values, and practices. METHOD: A mixed-method design using an online survey was used to collect and analyze demographic data and teaching philosophy statements from 375 ANEs. Coding was done via direct correct analysis. Themes were identified to capture the essence of the coded statements. RESULTS: EBP and its components were mentioned 275 times collectively; 44 ANEs specifically mentioned EBP in their teaching philosophies. other components were mentioned more frequently. three themes emerged: keeping up-to-date, setting up student success with EBP, and EBP as a teaching approach. CONCLUSION: The incorporation of EBP and its components was not widely acknowledged by ANEs. PMID- 29194133 TI - Nurse Residency Programs: An integrative Review of the Literature. AB - AIM: The aim is to explore nurse residency programs described in the literature and evaluate the evidence supporting their use. BACKGROUND: The Institute of medicine and the Joint Commission recommend that organizations provide nurse residency programs for newly licensed nurses. METHOD: An integrative review was conducted of empirical and program development articles published from 2006 to july 2013. RESULTS: Most articles included in this study had limitations, which are discussed. CONCLUSION: The literature demonstrates benefits associated with NRPs. More evidence is needed to determine if NRPs contribute to nurse-sensitive patient outcomes, thereby influencing quality of nursing care. PMID- 29194134 TI - Competence Acquisition Using Simulated Learning Experiences: A Concept Analysis. AB - AIM: To report the findings of an analysis of the concept of competence acquisition when determined using simulated learning experiences. BACKGROUND: Competence of nursing students prior to entry into practice has been stressed by the Institute of Medicine. Competence can be evaluated via simulation; however, evaluation practices vary among schools of nursing. The link between competence acquisition in simulation and clinical competence has not been determined. METHOD: Employing the methodology of , articles included in this analysis were published in english in peer-reviewed journals from 2002 to 2012 and contained information on simulation outcomes related to competence. Thirty-five articles and one text were included in the final analysis. RESULTS: Essential elements of competence acquisition identified included authentic environment, demonstration, and evaluation. CONCLUSION: Use of a consistent language and framework to evaluate competence acquisition in simulation is recommended, as is future research to test the constructs. PMID- 29194135 TI - Complexity of Care: A Concept Analysis of Older Adult Health Care Experiences. AB - PURPOSE: To define the term complexity of care. BACKGROUND: The aging population and lack of gerontological preparation in pre-licensure nursing programs are pressing issues. The NLN Advancing Care Excellence for Seniors (ACE.S) project developed a framework to facilitate faculty and student understanding of older adults' care needs. Integral to the framework is the concept of complexity of care. METHOD: Rogers and Knafl's evolutionary method of concept analysis was used. RESULTS: The analysis identified three antecedents (focus on treatment and cure of disease, multiple comorbidities, and life experiences and culture), five attributes (polypharmacy, use of advanced technologies, novel care models, a fragmented health care system, and the relational nature of caregiving), and two consequences (impact on quality of life and impact on quality of care). CONCLUSION: Defining the concept of complexity of care will facilitate student understanding of the unique health care needs of older adults.

AB - : The researchers used a quantitative pretest-posttest nonequivalent control group quasi-experimental design to determine if there is a significant difference in content knowledge acquisition between traditional and flipped classroom methods. Analysis revealed that the flipped classroom approach was significantly different for three unit exams. The results did not show a significant difference in the means for the final exam. Knowledge gains on tests and students' positive responses support the use of the flipped classroom method. PMID- 29194137 TI - Measuring Confidence in Nursing Graduates Within the Framework of the AACN Essentials. AB - : The American Association of Colleges of Nursing (AACN) Essentials of Baccalaureate Education provide a framework for assessment of nursing programs. The purpose of this pilot study was to determine if there was a difference in self-perceived confidence in meeting the AACN essentials between senior students who completed a traditional clinical course and those in a preceptorship course. A descriptive, comparative design was used. The results indicate that students who completed both course models had similarly high levels of perceived confidence in meeting the majority of the AACN essentials.

AB - : The purpose of this study was to describe learner perception, expected competence, and factors influencing satisfaction with team-based learning in a nursing course. Four-hour TBL sessions were given in a structured three-phase sequence for a cohort of 139 second-year nursing students. TBL was found to be an effective instructional strategy inducing team learning and self-directed learning. Nursing educators should improve TBL quality by focusing on the student team learning process. PMID- 29194139 TI - Nursing as an Additional Language and Culture (NALC): Supporting Student Success in a Second-Degree Nursing Program. AB - : The nursing workforce does not represent the diversity of the United States population and while recruitment of diverse nursing students is high, so are their rates of attrition. The Nursing as an Additional Language and Culture Program (NALC) was implemented in an accelerated, second-degree baccalaureate nursing program to enhance retention by minimizing barriers and supporting activities to enhance student success. Results suggest that the NALC program was successful in decreasing the attrition rate of nursing students, including minority students. PMID- 29194140 TI - High-Fidelity Simulation for Senior Maternity Nursing Students. AB - : This retrospective study examined the effectiveness of high-fidelity simulation (HFS) in a senior maternity baccalaureate nursing program. The study specifically focused on whether students who received instruction through HFS in addition to traditional hospital-based clinical instruction achieved greater practical learning, critical thinking skills, and NCLEX performance potential. Bandura's theory of self-efficacy guided the study. Simulation students (n = 132) were found to score significantly better than nonsimulation students (n = 147) in each area. Use of HFS may foster the development of competent and clinically prepared nurses. PMID- 29194141 TI - Navigating Evidence-Based Practice Projects: The Faculty Role. AB - : An innovative way to facilitate evidence-based practice (EBP) learning and to get evidence into practice is through academic-clinical agency projects involving faculty, undergraduate students, and agency staff. The central role of the faculty is key to successful academic-clinical agency partnerships. Faculty navigate the often difficult process of focusing students and engaging busy staff through initiating, maintaining, and evaluating projects. Students learn valuable EBP skills, staff become engaged in EBP, and the projects are rated highly by agency administrators.

PMID- 29194144 TI - Thoracic Epidural Analgesia and Mortality in Acute Pancreatitis: A Multicenter Propensity Analysis. AB - OBJECTIVE: Recent preclinical and clinical data suggest that thoracic epidural analgesia, a technique primarily aimed at decreasing pain, might exert anti inflammatory effects, enhance splanchnic and pancreatic blood flow during acute pancreatitis; however, the influence of epidural analgesia on mortality remains under investigated in this setting. This study was therefore designed to assess the impact of epidural analgesia on mortality in ICU patients with acute pancreatitis. DESIGN: Multicenter retrospective, observational, cohort study. SETTING: Seventeen French and Belgian ICUs. PATIENTS: All patients admitted to with acute pancreatitis between June 2009 and March 2014. INTERVENTIONS: The primary exposure was thoracic epidural analgesia versus standard care without epidural analgesia. The primary outcome was 30-day mortality. Propensity analyses were used to control for bias in treatment assignment and prognostic imbalances. MEASUREMENTS AND MAIN RESULTS: One thousand three ICU patients with acute pancreatitis were enrolled, of whom 212 died within 30 days. Epidural analgesia was used in 46 patients and was associated with reduced mortality in unadjusted analyses (4% vs. 22%; p = 0.003). After adjustment for baseline variables associated with mortality, epidural analgesia was still an independent predictor of 30-day mortality (adjusted odds ratio, 0.10; [95% CI, 0.02-0.49]; p = 0.004). Using propensity score analysis, the risk of all-cause 30-day mortality in patients with acute pancreatitis receiving epidural analgesia was significantly lower than that in matched patients who did not receive epidural analgesia (2% vs. 17%; p = 0.01). CONCLUSIONS: Among critically ill patients with acute pancreatitis, mortality at 30 days was lower in patients who received epidural analgesia than in comparable patients who did not. These findings support ongoing research on the use of epidural analgesia as a therapeutic intervention in acute pancreatitis. PMID- 29194145 TI - Continuous Infusion of Low-Dose Iohexol Measures Changing Glomerular Filtration Rate in Critically Ill Patients. AB - OBJECTIVE: Measurement of changing glomerular filtration rate in acute kidney injury remains problematic. We have previously used a continuous infusion of low dose Iohexol to measure glomerular filtration rate in stable subjects and postulate that changes greater than 10.3% in critically ill patients indicate acute kidney injury. Our objective is to explore the extent to which continuous infusion of low-dose Iohexol can be a measure of changing glomerular filtration rate during acute kidney injury. DESIGN: Clinical observational exploratory study. SETTING: Adult ICU. PATIENTS: Three patient groups were recruited: nephrectomy group: predictable onset of acute kidney injury and outcome (n = 10); surgery group: predictable onset of acute kidney injury, unpredictable outcome (n = 11); and acute kidney injury group: unpredictable onset of acute kidney injury and outcome (n = 13). INTERVENTIONS: Continuous infusion of low-dose Iohexol was administered for 24-80 hours. Plasma (ClP) and renal (ClR) Iohexol clearances were measured at timed intervals. MEASUREMENTS AND MAIN RESULTS: Kidney Disease: Improved Global Outcomes acute kidney injury criteria were fulfilled in 22 patients (nephrectomy = 5, surgery = 4, and acute kidney injury = 13); continuous infusion of low-dose Iohexol demonstrated acute kidney injury in 29 patients (nephrectomy = 10, surgery = 8, acute kidney injury = 11). Dynamic changes in glomerular filtration rate were tracked in all patients. In the nephrectomy group, ClR decreased by an expected 50% (50.8% +/- 11.0%). Agreement between ClP and ClR improved with increasing duration of infusion: bias of ClP versus ClR at 48 hours was -0.1 +/- 3.6 mL/min/1.73 m (limits of agreement: -7.2 to 7.1 mL/min/1.73 m). Coefficient of variation of laboratory sample analysis was 2.4%. CONCLUSIONS: Continuous infusion of low-dose Iohexol is accurate and precise when measuring glomerular filtration rate and tracks changes in patients with differing risks of acute kidney injury. Continuous infusion of low-dose Iohexol may provide a useful standard against which to test novel biomarkers for the diagnosis of acute kidney injury. PMID- 29194146 TI - Risk Factors of Impaired Neuropsychologic Outcome in School-Aged Survivors of Neonatal Critical Illness. AB - OBJECTIVE: Until now, long-term outcome studies have focused on general cognitive functioning and its risk factors following neonatal extracorporeal membrane oxygenation and/or congenital diaphragmatic hernia. However, it is currently unknown which neuropsychological domains are most affected in these patients and which clinical variables can be used to predict specific neuropsychological problems. This study aimed to identify affected neuropsychological domains and its clinical determinants in survivors of neonatal extracorporeal membrane oxygenation and/or congenital diaphragmatic hernia. DESIGN: Prospective follow-up study. SETTING: Tertiary university hospital. PATIENTS: Sixty-five 8-year-old survivors of neonatal extracorporeal membrane oxygenation and/or congenital diaphragmatic hernia. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Intelligence, attention, memory, executive functioning and visuospatial processing were evaluated using validated tests and compared with Dutch reference data. Assessed risk factors of outcome were illness severity indicators, number of anesthetic procedures in the first year of life, and growth at 1 year. Patients had average intelligence (mean intelligence quotient +/- SD, 95 +/- 16), but significantly poorer sustained attention (mean z score +/- SD, -2.73 +/- 2.57), verbal (immediate, -1.09 +/- 1.27; delayed, -1.14 +/- 1.86), and visuospatial memory (immediate, -1.48 +/- 1.02; delayed, -1.57 +/- 1.01; recognition, -1.07 +/- 3.10) than the norm. Extracorporeal membrane oxygenation treated congenital diaphragmatic hernia patients had significantly lower mean intelligence quotient (84 +/- 12) than other neonatal extracorporeal membrane oxygenation patients (94 +/- 10) and congenital diaphragmatic hernia patients not treated with extracorporeal membrane oxygenation (100 +/- 20). Maximum vasoactive inotropic score was negatively associated with delayed verbal (B = -0.02; 95% CI, -0.03 to -0.002; p = 0.026) and visuospatial memory (B = -0.01; 95% CI, -0.02 to 0.001; p = 0.024). CONCLUSIONS: We found memory and attention deficits in 8-year old neonatal extracorporeal membrane oxygenation and congenital diaphragmatic hernia survivors. The maximum dose of vasoactive medication was negatively associated with verbal and visuospatial memory, which may suggest an effect of early cerebral hypoperfusion in determining these abnormalities. PMID- 29194147 TI - Severity of Illness Scores May Misclassify Critically Ill Obese Patients. AB - OBJECTIVE: Severity of illness scores rest on the assumption that patients have normal physiologic values at baseline and that patients with similar severity of illness scores have the same degree of deviation from their usual state. Prior studies have reported differences in baseline physiology, including laboratory markers, between obese and normal weight individuals, but these differences have not been analyzed in the ICU. We compared deviation from baseline of pertinent ICU laboratory test results between obese and normal weight patients, adjusted for the severity of illness. DESIGN: Retrospective cohort study in a large ICU database. SETTING: Tertiary teaching hospital. PATIENTS: Obese and normal weight patients who had laboratory results documented between 3 days and 1 year prior to hospital admission. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Seven hundred sixty-nine normal weight patients were compared with 1,258 obese patients. After adjusting for the severity of illness score, age, comorbidity index, baseline laboratory result, and ICU type, the following deviations were found to be statistically significant: WBC 0.80 (95% CI, 0.27-1.33) * 10/L; p = 0.003; log (blood urea nitrogen) 0.01 (95% CI, 0.00-0.02); p = 0.014; log (creatinine) 0.03 (95% CI, 0.02-0.05), p < 0.001; with all deviations higher in obese patients. A logistic regression analysis suggested that after adjusting for age and severity of illness at least one of these deviations had a statistically significant effect on hospital mortality (p = 0.009). CONCLUSIONS: Among patients with the same severity of illness score, we detected clinically small but significant deviations in WBC, creatinine, and blood urea nitrogen from baseline in obese compared with normal weight patients. These small deviations are likely to be increasingly important as bigger data are analyzed in increasingly precise ways. Recognition of the extent to which all critically ill patients may deviate from their own baseline may improve the objectivity, precision, and generalizability of ICU mortality prediction and severity adjustment models.

PMID- 29194150 TI - English-Language Proficiency, Academic Networks, and Academic Performance of Mexican American Baccalaureate Nursing Students. AB - AIM: We examine how academic networks mediate between English-language proficiency and academic performance. BACKGROUND: The relationship between English-language proficiency and academic performance remains inconclusive; it is possible that academic networks play a role in this relationship. Filling this knowledge gap is central to building best practices in teaching, and to evaluating the impact of networks on success. METHOD: Data were analyzed from 164 Mexican American nursing students. We used English Language Acculturation Scale (ELAS) items as predictors, interaction with academic networks as the mediating variable, and course grade as the outcome; regression analyses were performed. RESULTS: Interaction with academic networks correlated with grades; ELAS was not significant. Instead, academic networks mediated between entrance GPA and grades, an unexpected finding. CONCLUSION: Academic networks are critical in academic performance. However, only those students who have a history of high performance are likely to have or to activate academic networks. PMID- 29194151 TI - A Correlational Study of a Reading Comprehension Program and Attrition Rates of ESL Nursing Students in Texas. AB - AIM: The purpose of this study was to examine the associations between English as a second language (ESL), a reading comprehension program, and attrition rates of nursing students. BACKGROUND: Higher attrition rates of ESL nursing students are an assumption, seemingly based on anecdotal evidence. Data reflecting ESL student attrition should be measured and analyzed so that students can be identified prior to attrition. METHOD: A secondary analysis of a large database of 27 initial licensure programs in Texas was completed. RESULTS: Data analysis identified that ESL students who used a reading comprehension program were almost twice as likely to be off track or out of the program as ESL students who did not use the program. CONCLUSION: Nurse educators need to evaluate student profile characteristics in a comprehensive way when determining risk of attrition. PMID- 29194153 TI - Nursing Student Satisfaction with an Associate Nursing Program. AB - PURPOSE: The purpose of this study was to conduct a nationwide survey to understand the satisfaction of associate of science in nursing (ASN) students with a nursing program as a whole. BACKGROUND: Student satisfaction is viewed as an indicator of program success. Yet, nursing student satisfaction has not been sufficiently studied in the United States. METHOD: The Curriculum, Faculty, Social Interaction, and Environment model was used to support this nationwide study. Stratified random sampling was used to recruit 56 ASN programs from 31 US states for participation. RESULTS: The students rated their satisfaction with the nursing program as close to "satisfied." The faculty, curriculum, and social interaction significantly and positively predicted overall student satisfaction with a nursing program. CONCLUSION: A nursing program can evaluate students' satisfaction periodically to determine the impact of the educational experience on the program's performance. PMID- 29194152 TI - Cultural Competence in Rural Nursing Education: Are We There Yet? AB - AIM: This multimethod study assessed the capacity of nursing education programs to promote culturally congruent practice in a single rural state. BACKGROUND: An important objective of our HRSA-funded Advanced Education in Nursing grant was to increase nurse educator proficiency in teaching cultural concepts. This study served as a statewide baseline assessment to inform future faculty development efforts. METHOD: Subjects included faculty, graduate students, and clinical educators representing all levels of nursing education programs. Self-report cultural proficiency data were collected via survey while focus groups and electronic surveys were utilized to assess curricula. RESULTS: No significant differences in proficiency were found by faculty age or education. Qualitative data indicated that concepts of culture are not easily identified across the curriculum. CONCLUSION: There is need for increased and explicit focus on concepts of culture in nursing education programs to prepare nurses for culturally congruent practice with potential to reduce health disparities. PMID- 29194154 TI - Facilitating Educational Advancement of RNs to the Baccalaureate: What Are They Telling Us? AB - AIM: This metasynthesis assists in the interpretation of qualitative research performed to explore the experience of registered nurses who return to school to pursue a baccalaureate degree. Understanding these experiences is necessary to achieve the national goal of 80 percent of RNs having BSNs by 2020. BACKGROUND: As few as 21 percent of all RNs prepared at the associate or diploma level earn a baccalaureate degree. Experts believe that enhanced academic-clinical partnerships can result in an improvement. METHOD: Noblit and Hare's method was followed to increase understanding of the phenomena. RESULTS: Seven overarching themes are presented in the words of the 324 nurses included in the 13 qualitative studies in the sample. CONCLUSION: The experiences of these nurses provide information to inform partnerships for the development of effective, efficient, and meaningful educational pathways that acknowledge the challenges and needs of these professionals. PMID- 29194155 TI - Factors Influencing Retention Among Part-Time Clinical Nursing Faculty. AB - AIM: This study sought to determine job characteristics influencing retention of part-time clinical nurse faculty teaching in pre-licensure nursing education. BACKGROUND: Large numbers of part-time faculty are needed to educate students in the clinical setting. Faculty retention helps maintain consistency and may positively influence student learning. METHOD: A national sample of part-time clinical nurse faculty teaching in baccalaureate programs responded to a web based survey. Respondents were asked to identify the primary reason for wanting or not wanting to continue working for a school of nursing (SON). RESULTS: Affinity for students, pay and benefits, support, and feeling valued were the top three reasons given for continuing to work at an SON. Conflicts with life and other job responsibilities, low pay, and workload were the top three reasons given for not continuing. CONCLUSION: Results from this study can assist nursing programs in finding strategies to help reduce attrition among part-time clinical faculty. PMID- 29194156 TI - Graduate-Entry Non-Nursing Students: Is Emotional Intelligence the Difference? AB - : Despite numerous measures of their success, nurses from graduate nursing programs for non-nurses (GPNNN) often struggle to find acceptance in the workplace. Employers frequently describe these nurses' superior psycho/social capabilities when compared to traditionally educated nurses, but little substantiating quantitative data exist to support this. This study explored nursing students' psycho/social ability by comparing measured emotional intelligence (EI) ability among students from four nursing schools, including one GPNNN program. Findings included significantly higher scores in the EI subscore "understanding emotions" for GPNNN students over two of the three comparison nursing programs, even when data were controlled for age.

There is a dearth of empirical evidence supporting simulation in psychomotor skill learning and transfer of these skills to patient care. A two-group repeated measures pretest/posttest design with three measurement times was used. Scenario-based simulation served as the intervention. All subjects were posttested in the learning laboratory and clinical settings. The experimental group had higher adjusted means at both posttesting times, though these results were not statistically significant.

PMID- 29194159 TI - Evaluating Nurse Practitioner Students Through Objective Structured Clinical Examination. AB - : Medical schools' use of Objective Structured Clinical Examination (OSCE) for over 30 years proves the OSCE is an objective way to assess a variety of clinical skills. This pilot study determined the feasibility of using OSCE, together with a checklist tool, to evaluate nurse practitioner (NP) students' competency in obtaining a patient's health history and performing a complete physical examination. In this descriptive study, four NP faculty viewed a prerecorded OSCE video of a student/ patient encounter and scored it using a checklist to determine the student's competency. Faculty showed a strong degree of agreement in grading competence. Findings suggest OSCEs could be an effective means of student evaluation, but revising the checklist to align with NP national competencies would make it meaningful for NP evaluation specifically.

Faculty, community nurses, and students who participated in interviews were asked to complete a five-item, open-ended survey. Data analysis revealed that they enjoyed the process and identified it as beneficial. A positive aspect included students' getting to present themselves as more than a GPA. The use of group interviews provides additional information for faculty who are challenged with selecting students for enrollment in programs of nursing.

AB - : This article describes the implementation and outcomes of a pediatric clinical education pilot project at a weekend overnight camp for children with special needs. Nine junior-level baccalaureate students participated in the immersion experience. The course skill inventory, an instructor-led postconference, a focus group session, and online forum entries were used to evaluate the experience. The evidence suggests that students gained a wide variety of psychomotor skills and patient-centered care attitudes. Although scheduling was challenging, we concluded the camp clinical was an enlightening and positive experience that offered opportunities not readily available in the hospital setting.

PMID- 29194165 TI - Clinical Characteristics and Risk Factors of Long-term Central Venous Catheter associated Bloodstream Infections in Children. AB - BACKGROUND: Central line-associated bloodstream infections (CLABSIs) account for significant morbidity and mortality in patients with long-term central venous catheters (CVCs). This study was performed to identify the characteristics and risk factors of CLABSIs among children with long-term CVCs. METHODS: A retrospective review of children who had a long-term CVC in Seoul National University Children's Hospital between 2011 and 2015 was performed. Data on patient demographics, the isolated pathogens and the status of CVC placement were collected. Clinical variables were compared between subjects with and without CLABSIs to determine the risk factors for CLABSIs. RESULTS: A total of 629 CVCs were inserted in 499 children during the 5-year period. The median age at insertion was 6.0 years (14 days-17.9 years), and hemato-oncologic disease was the most common underlying condition (n = 497, 79.0%). A total of 235 CLABSI episodes occurred in 155 children, with a rate of 0.93 per 1,000 catheter days. The most common pathogens were Klebsiella pneumoniae (n = 64, 27.2%), coagulase negative staphylococci (n = 40, 17.0%) and Staphylococcus aureus (n = 28, 12.0%). In the univariate analysis, the gender, underlying disease, catheter characteristics and insertion technique did not increase the risk for CLABSI. In both the univariate and logistic regression analyses, patients with prior BSIs (odds ratio 1.66; 95% confidence interval: 1.090-2.531; P = 0.018) were more likely to have a CLABSI. CONCLUSIONS: CLABSI prevention is of particular concern for children with a prior BSI. Furthermore, the antimicrobial resistance of major pathogens should be monitored to enable the empiric selection of appropriate antibiotics in patients with long-term CVCs.

AB - OBJECTIVE: The objective of this study was to determine the emergence of pain in critical-care nurses and the prognostic risk factors. DESIGN: This study is a cross-sectional descriptive research. SETTING AND SUBJECTS: This study was conducted with the participation of 111 critical-care nurses in Zonguldak province, Turkey. INTERVENTIONS: The data were collected using a survey form and the Cornell Musculoskeletal Discomfort Questionnaire between August and November 2015. The data were evaluated using frequency, average, Pearson correlation analysis, chi, logistic regression, and odds ratio tests. RESULTS: The critical care nurses were found to experience pain mostly in their lower backs (88.3%), upper backs (77.5%), right (76.6%) and left (78.4%) feet, necks (73.9%), and most infrequently in the right (28.8%) and left (28.8%) lower arms. Changing bed linens while the patient remained in bed and lifting, pulling, or pushing heavy materials caused those nurses who felt despondent and tired to feel significant pain in the shoulder, neck, upper arm, wrist, and knee (P < .05). CONCLUSIONS: These results were significant for placing emphasis on maintaining body mechanics while caring for patients, providing appropriate environmental conditions, and ensuring ergonomics to preserve the health of critical-care nurses who work in hospitals. PMID- 29194169 TI - Quality of Life of Adult Survivors After Extra Corporeal Membrane Oxygenation (ECMO): A Quantitative Study. AB - INTRODUCTION: Extracorporeal Membrane Oxygenation (ECMO) is a technique used in the treatment of patients with severe respiratory failure. A lot of studies in the literature investigated the survival rate of patients treated with ECMO, but few are those that assess the long-term outcomes and the quality of life (QoL) of survivors. MATERIALS AND METHODS: A retrospective observational study with prospective QoL assessment through administration of the questionnaire EuroQol-5 Dimension was conducted in acute respiratory distress syndrome patients who h ad ECMO as a rescue therapy for reversible refractory hypoxemia from January 2013 until December 2015 in an Italian referral ECMO center. RESULTS: Forty patients were enrolled, but the telephone interview was possible only in 17. The interviewed patients presented a reduction in QoL in the items concerning pain (59%), followed by problems regarding mobility (47%) and anxiety (47%). The patients' perceived QoL, showed in a 0 to100 scale (0 being the worst, 100 being the best value), is of 75% (interquartile range, 70-80). DISCUSSION: The problems found are in agreement with the literature about this particular type of patients. CONCLUSION: Most ECMO patients have good physical and social functioning after hospital discharge. PMID- 29194170 TI - Collaborating With Hospital Chaplains to Meet the Spiritual Needs of Critical Care Patients. AB - There are many opportunities for critical-care nurses to collaborate with chaplains in an effort to provide spiritual care for patients and their families. By recognizing the educational requirements as well as the unique roles of board certified chaplains (BCCs), the critical-care nurse will view them as respected members of the health care team. This collaboration positively impacts the work environment and creates a holistic space for healing for patients, as well as the health care team. As nurses, we must educate and inform novice nurses about the important role of BCCs on the interdisciplinary health care team. Critical-care nurses need to incorporate the BCCs' contributions into the patient plan of care during bedside report in a way that helps the nurse understand the connection between the patient's spiritual health and his/her experience as a patient. PMID- 29194171 TI - Improving the Accuracy of Delirium Assessments in Neuroscience Patients: Scaling a Quality Improvement Program to Improve Nurses' Skill, Compliance, and Accuracy in the Use of the Confusion Assessment Method in the Intensive Care Unit Tool. AB - BACKGROUND: Delirium affects up to 80% of critically ill patients; however, many cases of delirium go unrecognized because of inaccurate assessments. The effectiveness of interventions to improve assessment accuracy among the general population has been established, but assessments among neuroscience patients are uniquely complicated due to the presence of structural neurologic changes. OBJECTIVES: The purposes of this quality improvement project were to improve the accuracy of nurse's delirium assessments among neuroscience patients and to determine the comparative effectiveness of the intervention between medical and neuroscience patients. METHODS: A multifaceted nurse-led intervention was implemented, and a retrospective analysis of preintervention and postintervention data on assessment accuracy was completed. Results were stratified by population, level of sedation, and level of care. Differences were analyzed using Fisher exact test. RESULTS: Data from 1052 delirium assessments were analyzed and demonstrated improvement in assessment accuracy from 56.82% to 95.07% among all patients and from 29.79% to 92.98% among sedate or agitated patients. Although baseline accuracy was significantly lower among neuroscience patients versus medical intensive care unit patients, no significant differences in postintervention accuracy were noted between groups. CONCLUSION: Results from this project demonstrate the effectiveness of the nurse-led intervention among neuroscience patients. Future research is needed to explore the effectiveness of this nurse-led intervention across other institutions and to describe the effectiveness of new interventions to improve outcomes at the patient and organizational levels. PMID- 29194173 TI - Unit-Level Changes in Central Line-Associated Bloodstream Infection Before and After Implementation of the Affordable Care Act and Mandatory Reporting Legislation. AB - BACKGROUND: Central line-associated bloodstream infection (CLABSI) prevention efforts have increased over the past decade because of implications of the Affordable Care Act and mandatory reporting laws. These legislative measures allow for reduced reimbursement to hospitals with high level of CLABSIs and other health care-associated infections. OBJECTIVE: The aim of this study was to explore the impact of legislation and mandatory reporting on CLABSI rates and reporting. METHODS: The study team performed a retrospective review of medical intensive care unit patients in January 2008, 2012, and 2015 to examine changes in CLABSI reporting by 2 methods (International Classification of Diseases [ICD] by providers and Centers for Disease Control by infection prevention [IP]), as well as changes in central line use over time. Data were summarized and compared. Percent agreement and kappa statistics were calculated for ICD- and IP-coded CLABSIs. RESULTS: Among 465 intensive care unit patients, most were white (89.9%), males (52.0%), aged 58.7 +/- 17.1 years. Only 3 new CLABSIs were reported during the study period: 2 by ICD and IP in 2008, 1 by ICD in 2012, and 0 by either method in 2015. The percent agreement (99.6%) and kappa (0.799) represent excellent agreement. Central line usage was similar for each time period. DISCUSSION: The number of CLABSIs decreased over time; however, the findings were limited, and a larger sample over a longer period is needed to draw conclusions about the influence of legislative changes. One discrepancy was observed between the 2 reporting methods, which is consistent with other studies. More research is needed to understand the complexity of provider coding practices and changes in central line use (eg, duration, type, location) over time. PMID- 29194174 TI - The Effects of Endotracheal Suctioning in the Pediatric Population: An Integrative Review. AB - BACKGROUND: Critically ill pediatric patients with endotracheal tubes routinely receive endotracheal tube suctioning to clear secretions and ensure tube patency. This common practice can result in adverse effects. OBJECTIVES: The aim of this study was to evaluate the research literature on the stressors of endotracheal suctioning and consequent effect on the pediatric patient. METHODS: An integrative review was conducted using the Whittemore and Knafl modified framework for integrative reviews, and article selection was guided by the Preferred Reporting Items for Systematic Reviews and Meta-analyses flow diagram. A literature search was conducted via PubMed, the Cumulative Index to Nursing and Allied Health Literature, and Scopus. Selected articles were evaluated to present the current evidence on the stressors of endotracheal suctioning in the pediatric population. RESULTS: This review includes 14 articles, with a total of 849 patients, ranging in age from premature neonates to 17 years of age. The available literature aligned into 3 categories: neurovascular effects, respiratory systems effects, and pain related to endotracheal tube suctioning. Pain was the most prevalent category, with half of the studies using endotracheal suctioning as a painful procedure to validate pain assessment tools rather than examining the effect of suctioning. A majority of the studies (67%) were conducted in the premature neonate population. Children with congenital cardiac or pulmonary defects, genetic syndromes, or neurological injuries were frequently excluded. CONCLUSIONS: Literature regarding the effects of endotracheal suctioning in children is limited. There are many extrapersonal, interpersonal, and intrapersonal stressors associated with endotracheal suctioning that merit future research. PMID- 29194177 TI - Efficacy of a Micro-Prompting Technology in Reducing Support Needed by People With Severe Acquired Brain Injury in Activities of Daily Living: A Randomized Control Trial. AB - OBJECTIVE: To evaluate the effectiveness of an automated interactive prompting technology in supporting the morning routine of persons with acquired brain injury. The morning routine included maintaining personal hygiene and dressing. SETTING: An inpatient neurorehabilitation hospital. PARTICIPANTS: Persons with acquired brain injury who required prompting when following their morning routine (n = 24), but were not limited by physical disability or dysphasia, took part in the study. Participants (67% with traumatic brain injury) had impairment on indices of memory and executive function. DESIGN: A randomized control trial evaluated the effect of an automated interactive micro-prompting device on the number of prompts by trained staff required for successful completion of the morning routine. MAIN MEASURES: Study-specific checklists assessed sequence performance, errors, and verbal prompts required over baseline, rehabilitation as usual, intervention, and return to baseline conditions. RESULTS: The intervention significantly reduced the support required to complete the task compared with usual rehabilitation. CONCLUSIONS: Micro-prompting technology is an effective assistive technology for cognition, which reduces support needs in people with significant cognitive impairments. PMID- 29194176 TI - Racial Disparities in Outpatient Mental Health Service Use Among Children Hospitalized for Traumatic Brain Injury. AB - OBJECTIVE: To examine racial differences in mental health service utilization after hospitalization for traumatic brain injury (TBI) among children with Medicaid insurance. DESIGN AND MAIN MEASURES: Retrospective analysis of the MarketScan Multi-State Medicaid database from 2007 to 2012 was performed. Outpatient mental health service utilization (psychiatric and psychological individual and group services) was compared at TBI hospitalization, from discharge to 3 months and from 4 to 12 months after discharge, between children of non-Hispanic white (NHW), non-Hispanic black (NHB), Hispanic, and "Other" racial groups. Multivariable mixed-effects Poisson regression models with robust standard errors were utilized. RESULTS: A total of 5674 children (aged <21 years) were included in the study. There were no differences by race/ethnicity in mental health service utilization during hospitalization. At 3 months postdischarge, NHB children and children in the "Other" racial category were significantly less likely to receive outpatient mental health services than NHW children (NHB relative risk [RR] = 0.84; 95% confidence interval [CI], 0.72-0.98; Other RR = 0.72; 95% CI, 0.57-0.90). At 12 months, all racial minority children were significantly less likely to receive outpatient mental health services than NHW children (NHB RR = 0.84; 95% CI, 0.75-0.94; Hispanic RR = 0.72; 95% CI, 0.55 0.94; Other RR = 0.71; 95% CI, 0.60-0.84). CONCLUSIONS: Racial disparities in utilization of outpatient mental health services exist for minority children hospitalized for TBI and insured by Medicaid. Future research should focus on improving transitions of care from inpatient to outpatient services for these children. PMID- 29194178 TI - Relationship Between Neurocognitive Function and Self-Discrepancy After Severe Traumatic Brain Injury. AB - OBJECTIVE: Individuals with traumatic brain injury (TBI) often make unfavorable comparisons between their preinjury and postinjury selves. Although it is known that negative "self-discrepancy" is related to poorer emotional adjustment, the impact of neurocognitive function on self-discrepancy is unclear. This study aimed to investigate the relationship between current neurocognitive function (attention, memory, executive function, and self-awareness) and self-discrepancy after severe TBI. DESIGN: Fifty-four adults with severe TBI were recruited from outpatient and community rehabilitation services and completed measures of self discrepancy (Head Injury Semantic Differential Scale-III) and self-awareness (Awareness Questionnaire) and a battery of standardized tests of attention, memory, and executive functions. RESULTS: More negative self-discrepancy was significantly associated with greater self-awareness (r = -0.40, P < .001) and better performance on tests of immediate memory (r = -0.43, P < .01), working memory (r = -0.35, P < .05), and verbal fluency (r = -0.34, P < .05). Self awareness was the only neurocognitive factor significantly and uniquely related to self-discrepancy, accounting for 8.6% of the variance (P < .05). Furthermore, self-awareness was found to partially mediate the relationship between immediate memory and self-discrepancy. CONCLUSION: Better neurocognitive function is related to more negative self-discrepancy. These findings improve understanding of the process of identity reconstruction following TBI. PMID- 29194179 TI - Correspondence of the Boston Assessment of Traumatic Brain Injury-Lifetime and the VA Comprehensive TBI Evaluation. AB - OBJECTIVE: To compare the diagnosis of positive versus negative for mild traumatic brain injury (mTBI) using the Boston Assessment of TBI-Lifetime (BAT L), a validated forensic clinical interview used to identify TBI in research, to the diagnosis of mTBI in the clinical polytrauma service using the Comprehensive TBI Evaluation (CTBIE). PARTICIPANTS: Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn Veterans who were enrolled in the Translational Research Center for TBI and Stress Disorders longitudinal cohort study and received a CTBIE at a Veterans Health Administration healthcare facility (n = 104). MAIN MEASURES: The BAT-L, CTBIE, and Neurobehavioral Symptom Inventory. RESULTS: There was poor correspondence between the BAT-L and CTBIE mTBI diagnoses (kappa = 0.283). The CTBIE showed moderate sensitivity but poor specificity relative to the BAT-L. The agreement did not improve after removing individuals who had failed symptom validity measures, as assessed by the Validity-10 scale of the Neurobehavioral Symptom Inventory. CONCLUSIONS: This lack of correspondence highlights the difficulties in diagnosing mTBI in Veterans using retrospective self-report. Future work is needed to establish a reliable and valid method for identifying military mTBI both for the care of our Veterans and for appropriate distribution of benefits. PMID- 29194180 TI - Agitated Behavior and Activities of Daily Living Retraining During Posttraumatic Amnesia. AB - BACKGROUND: Patients in posttraumatic amnesia (PTA) may receive limited rehabilitation due to the risk of overstimulation and agitation. This assumption has not been tested. OBJECTIVE: To examine the relationship between agitated behavior and participation in therapy for retraining of activities of daily living (ADL) while in PTA. SETTING: Inpatient rehabilitation center. PARTICIPANTS: A total of 104 participants with severe traumatic brain injury, admitted to rehabilitation, in PTA of more than 7 days. INTERVENTION: ADL retraining during PTA followed errorless and procedural learning principles. DESIGN: Group comparison and regression modeling of patient agitation data from a randomized controlled trial comparing ADL retraining in PTA (treatment) versus no ADL retraining in PTA (treatment as usual, TAU). OUTCOME MEASURES: Agitation using the Agitated Behavior Scale. Therapy participation measured in minutes and missed sessions. RESULTS: There were no group differences in agitated behavior (average scores, peak scores, or number of clinically agitated days) between the treatment and TAU groups. For treated patients, there was no significant relationship between agitation and therapy participation (therapy minutes or missed ADL treatment sessions). CONCLUSIONS: This study demonstrated that agitation is not increased by delivery of structured ADL retraining during PTA and agitation did not limit therapy participation. This supports the consideration of active therapy during PTA. PMID- 29194181 TI - Feasibility of a Skills-Based Group Reintegration Workshop for OEF/OIF Veterans: STEP-Home. AB - OBJECTIVE: To evaluate the feasibility of a newly developed reintegration workshop for Operation Iraqi Freedom/Operation Enduring Freedom (OEF/OIF) Veterans that is based on an evidence-based rehabilitation program shown to be effective in treating mild traumatic brain injury-related symptoms in civilians. Underutilization and resistance to mental health treatment remain a significant problem for OEF/OIF Veterans. Innovative, integrative, transdiagnostic, and acceptable interventions are needed, particularly for this heterogeneous group. PARTICIPANTS: Eighty-four OEF/OIF/Operation New Dawn Veterans (74 male and 10 female)-mean age = 35; standard deviation = 7.4. SETTING: VA Healthcare System. INTERVENTION: A 12-week, 2-hour/wk, group skills-based workshop with individual skill building to assist all OEF/OIF Veterans (with and without psychiatric and/or traumatic brain injury) in reintegration after military service. MAIN MEASURES: Primary outcomes were feasibility measures including treatment fidelity, acceptability, tolerability/adherence, and treatment-related skill acquisition. Secondary outcomes were interest and engagement in future treatment and reintegration status. RESULTS: Veterans' enrollment, adherence, and attrition data indicated that Short-Term Executive Plus adapted for Veteran civilian reintegration (STEP-Home) was acceptable and tolerable. Pre-/postintervention differences in attention, problem-solving, and emotional regulation skills demonstrated treatment-related skills acquisition. Secondary outcome data demonstrated Veterans who were hesitant to participate in mental health treatments before enrollment were more open to treatment engagement after STEP Home, and reintegration status improved. CONCLUSIONS: This study demonstrated that the STEP-Home workshop is feasible in OEF/OIF Veterans and changes in treatment-related skill acquisition and reintegration status were observed. STEP Home has potential to facilitate readjustment and serves as a gateway to additional, critically needed Veterans Administration services. PMID- 29194182 TI - Effect of Postactivation Potentiation Induced by Elastic Resistance on Kinematics and Performance in a Roundhouse Kick of Trained Martial Arts Practitioners. AB - Aandahl, HS, Von Heimburg, E, and Van den Tillaar, R. Effect of postactivation potentiation induced by elastic resistance on kinematics and performance in a roundhouse kick of trained martial arts practitioners. J Strength Cond Res 32(4): 990-996, 2018-The aim of this study was to examine whether kicking with elastic resistance during warm-up could initiate postactivation potentiation (PAP), and thereby positively influence kinematics and performance on subsequent explosive roundhouse kicking. Five women and 11 men (n = 16) with a background in kickboxing (n = 10) or taekwondo (n = 6) performed 2 warm-up strategies with 3 subsequent test kicks 5-8 minutes after a PAP-inducing exercise. Kicking performance, defined as roundhouse kicking velocity with the foot, was measured using 3D motion capture (500 Hz) with a 15 marker lower-body 3D model. In addition, electromyography of the prime movers-vastus lateralis, vastus medialis, and rectus femoris muscles-was measured to confirm the presence of PAP. Kicking velocity of the foot increased by 3.3% after performing a warming-up strategy including kicking with elastic resistance (p = 0.009, eta = 0.32). Increases were also recorded in muscle activity in vastus medialis (35.2%, p = 0.05, eta = 0.18) and rectus femoris (43.9%, p = 0.04, eta = 0.20). These findings indicate that performing a warm-up strategy including kicking with elastic resistance can have a positive effect on kicking performance in a roundhouse kick. PMID- 29194184 TI - Biomechanical Comparison of Loaded Countermovement Jumps Performed on Land and in Water. AB - Researchers have observed physical improvements following the completion of aquatic-based jump training. However, there is a lack of research on the biomechanical specificity of aquatic-based movement. Therefore, the purpose of this investigation was to evaluate the kinetics and kinematics of loaded countermovement jumps performed in water versus land. Twenty young males and twenty-four NCAA division I women's soccer and gymnastics athletes were asked to perform unloaded and loaded countermovement jumps on land and in chest-deep water immersion. A tri-axial force platform and two dimensional videography produced various kinetic and kinematic measures of jump performance. Peak and mean mechanical power outputs (W) were 88% (8919+/-3744W vs. 4734+/-1418W; p<0.001) and 81% (3640+/-1807W vs. 2011+/-736W; p<0.001) greater for jumps performed in water versus land. Peak dorsiflexion velocity was 688% faster (44+/-39 degrees /s vs. 5.6+/-5.4 degrees /s; p<0.001) for jumps performed in water and tended to model similarly with measures of mechanical power and amortization rate. Bodyweight normalized peak and mean mechanical power outputs decreased by 23.6+/ 2.7% and 23.8+/-1.9% when load was added in the water. The addition of load on land was associated with an 8.7+/-2.3% and 10.5+/-4.4% decrease in bodyweight normalized peak and mean mechanical power. Results suggest that the aquatic environment alters movement primarily at amortization and may provide a unique training stimulus. Also, it can be concluded that fluid resistance and buoyancy combine to influence the mechanics of jumping movements performed in the water. PMID- 29194183 TI - Hyperactivity of the Sympatho-Adrenomedullary System Without Any Modification of the Hypothalamic-Pituitary-Adrenal Axis After Food Restriction Among High-Level Weightlifters. AB - Durguerian, A, Filaire, E, Drogou, C, Sauvet, F, Bougard, C, and Chennaoui, M. Hyperactivity of the sympatho-adrenomedullary system without any modification of the hypothalamic-pituitary-adrenal axis after food restriction among high-level weightlifters. J Strength Cond Res 32(6): 1643-1655, 2018-We examined the effects of 6 days of food restriction on salivary alpha-amylase (sAA), cortisol and dehydroepiandrostenedione (DHEA) awakening responses, psychological parameters and performance among 11 international weightlifters. Assessments were made at baseline (T1) and 6 days after a normal period of training while maintaining body weight (T2). Then, participants were assigned to 2 groups depending on whether they lost (Diet group) or maintained (Control group) their body mass. Anthropometric, psychological, physical, and physiological assessments were also realized 6 days (T3) after the restricted dietary period for the Diet group. Food restriction (T3) induced a significant rise of sAA awakening response (364.6%, p <= 0.05), whereas no significant variations were observed among the hypothalamic pituitary-adrenal axis (cortisol and DHEA). Significant alterations of the general Recovery Score and General stress Score, evaluated through the Recovery Stress Questionnaire for athletes, were noted after food restriction. Weightlifting performance, evaluated during a simulated weightlifting competition, was maintained after the 6-day food restriction; we even noted an increased weightlifting performance related to body mass (Sinclair coefficient). Our findings support the hypothesis that food restriction induces a challenging situation to the organism, resulting in an asymmetry between the 2 stress systems activation. These results reinforce the necessity to cautiously plan and monitor the weight regulation process before competition to avoid potential negative outcomes on psychophysiological parameters. In this regard, the psychobiological approach, especially the awakening responses, seems a useful tool. PMID- 29194185 TI - Does Maturity Status Affect The Relationship Between Anaerobic Speed Reserve And Multiple Sprints Sets Performance in Young Soccer Players? AB - The purpose of this study is to examine the relationship between repeated-sprint sets (RSS) performance indices and anaerobic speed reserve (ASR) in young soccer players of different maturity status. One hundred and seventy nine young male soccer players (11.1 to 17.8 years) classified as pre- (n=50), circum- (n=60), or post- (n=69) peak height velocity (PHV) performed multi-stage shuttle run test (MRST) to measure maximal aerobic speed (MAS), 30-m sprint with 10-m splits to estimate maximal anaerobic speed (MAnS), and RSS test. ASR was calculated as the difference between MAS and MAnS. The RSS indices, MAS, MAnS and ASR were significantly different in the three maturity groups (p< 0.001; ES =0.12-0.64). Correlations between RSS performance indices and ASR varied considerably depending on maturity status. Very large correlations between ASR and RSS indices expressed as sum sprint time (SST) and best sprint time (BST) were found for pre- and circum-PHV groups (r=-0.76, -0.79 and r=-0.82, -0.86, respectively). In the post-PHV group, ASR was moderately associated with both SST (r=-0.45) and BST (r= 0.46). To sum up, these results highlighted that the ASR is more related to factors of RSS performance in pre- and circum-PHV male soccer players compared with post-PHV ones. These findings could help coaches and strength and conditioning professionals to better understand how the relationship between ASR and RSS evolve across the maturity and may be considered, therefore, useful in youth soccer selection/training process. PMID- 29194186 TI - The Impact of Different Cross-Training Modalities on Performance and Injury Related Variables in High School Cross Country Runners. AB - Paquette, MR, Peel, SA, Smith, RE, Temme, M, and Dwyer, JN. The impact of different cross-training modalities on performance and injury-related variables in high school cross country runners. J Strength Cond Res 32(6): 1745-1753, 2018 There are many different types of aerobic cross-training modalities currently available. It is important to consider the effects that these different modalities have on running performance and injury risks. The purpose of this study was to compare movement quality, running economy (RE) and performance, injury-related biomechanical variables, and hip muscle strength before and after training with different cross-training modalities in high school runners. Thirty one high school male runners trained for 4 weeks in 1 of 3 cross-training modalities, in addition to a running-only (n = 9) group, for which training sessions replaced 2 easy runs per week: cycling (CYCLE; n = 6), indoor elliptical (n = 7), and outdoor elliptical bike (EBIKE; n = 9). Functional movement screen (FMS), RE, 3,000-m performance, hip kinematics, and hip muscle strength were assessed. Paired t-tests and Cohen's d effect sizes were used to assess mean differences for each variable before and after training within each group. Elliptical bike training was the only modality that improved FMS scores (d = 1.36) and RE before and after training (d = 0.48). All groups showed improvements in 3,000-m performance, but large effects were found only for the CYCLE (d = 1.50) and EBIKE (d = 1.41) groups. Running-only (d = 1.25), CYCLE (d = 1.17), and EBIKE (d = 0.82) groups showed improvements in maximal hip extensor strength. Outdoor cycling and EBIKE cross-training may be the most effective cross-training modalities to incorporate in early season training to improve running performance in high school runners. PMID- 29194187 TI - The prevalence of coronary artery disease in patients with liver cirrhosis: a meta-analysis. PMID- 29194189 TI - Ovarian Yolk Sac Tumors; Does Age Matter? AB - BACKGROUND: Whereas among pediatric oncologists, ovarian yolk sac tumor (O-YST) is considered a chemosensitive tumor, it is often cited as an adverse prognostic factor in adult women with ovarian germ cell tumors. METHODS: The Malignant Germ Cell International Consortium data set included 6 pediatric clinical trials (United States, United Kingdom, and France) and 2 adult gynecology clinical trials (United States). Any patient with an O-YST that was International Federation of Gynecology and Obstetrics stage IC or higher and treated with a platinum-based chemotherapy was eligible. Age was modeled as a continuous and a categorical variable (children, 0-10 years; adolescents, 11-17 years; and adults, >=18 years). In addition, analyses to establish the optimal cut point for age were conducted. Tumors were coded as pure YST (YST +/- teratoma), mixed YST (YST + other malignant germ cell component), or putative YST ("mixed" germ cell tumor + alpha-fetoprotein >1000 ng/mL). Histology, stage (II/III vs IV), preoperative alpha-fetoprotein levels (<1000; 1000-10,000, or >10,000 ng/mL), and chemotherapeutic regimen (carboplatin vs cisplatin) were analyzed as covariates. RESULTS: Two hundred fifty-one patients (median age, 13 years; range, 0-38 years) were identified (78 children, 139 adolescents, and 34 adults). Histology was pure, mixed, and putative in 129, 56, and 66 cases, respectively. Twenty-six patients had stage IV disease, similarly distributed in the 3 age groups. Median follow-up was 5.8 years. The overall 5-year event-free survival and overall survival was 91% (95% confidence interval, 87%-94%) and 96% (92%-98%), respectively. Age did not affect risk of event or death, modeled either as a categorical or continuous variable. Analysis failed to identify an age cut point that affected risk. None of the other covariates investigated had a prognostic impact on event-free survival or overall survival. CONCLUSIONS: Ovarian yolk sac tumors have an excellent outcome across all age-groups. Age has no apparent impact on the probability of event or death, allowing pediatric and gynecologic oncologists to enroll patients onto joint pediatric and adult trials. PMID- 29194190 TI - An Evaluation of Frozen Section and Lymph Node Dissection Results for Mucinous Ovarian Tumors. AB - OBJECTIVES: Intraoperative frozen section has greater than 90% accuracy for ovarian tumors; however, mucinous histology has been shown to be associated with increased frozen section inaccuracy. Recent data demonstrate that primary ovarian mucinous carcinomas have no lymph node involvement, even when extraovarian disease is present, and therefore may not require lymph node dissection. Our primary objective is to evaluate the accuracy of identifying mucinous histology on frozen section. METHODS/MATERIALS: A cross-sectional review of mucinous ovarian tumors in surgical patients at one institution from 2006 to 2016 was performed. Cases reporting a mucinous ovarian tumor on frozen section or final pathology were identified. Frozen section results were compared with final diagnosis to calculate concordance rates. Analyses with chi and t tests were performed to identify variables associated with pathology discordance. RESULTS: A total of 126 mucinous ovarian tumors were identified. Of these, 106 were reported as mucinous on frozen section and 103 (97.2%) were concordant on final pathology. Discordant cases included 2 serous and 1 clear cell tumor. Among the 103 mucinous tumors, classification as malignant, borderline, or benign was concordant in 74 (71.8%) of 103 cases, whereas 22 (21.4%) of 103 were discordant and 7 (6.8%) were deferred to final pathology. Lymph node dissection was performed in 33 cases; the only case with lymph node metastasis was a gastrointestinal mucinous adenocarcinoma. Discordance between frozen section and final pathology was associated with larger tumor size and diagnosis other than benign: discordant cases had a mean tumor size of 21.7 cm compared with 14.4 cm for concordant cases (P < 0.001), and 93.5% of discordant cases were borderline or malignant, compared with 30.5% of concordant cases (P < 0.001). CONCLUSIONS: Intraoperative identification of mucinous histology by frozen section is reliable with a concordance rate to final pathology of 97.2%. No lymph node metastases were present in any malignant or borderline primary ovarian cases. PMID- 29194191 TI - BRCA Mutation Status Is Not Associated With Increased Hematologic Toxicity Among Patients Undergoing Platinum-Based Chemotherapy for Ovarian Cancer. AB - OBJECTIVE: Women with an inherited BRCA1 or BRCA2 mutation may have an impaired ability to repair chemotherapy-induced damage as a result of a state of haploinsufficiency and may experience greater treatment-related toxicity. The objective of this study was to compare the hematologic adverse effect profiles associated with platinum-based chemotherapy in ovarian cancer patients with and without germline BRCA mutations. METHODS: We conducted a retrospective analysis of patients treated for high-grade serous ovarian cancer at Princess Margaret Cancer Center, Toronto, Ontario between January 2000 and December 2015. We included only women with known BRCA mutation status and who received first-line platinum-based chemotherapy. We compared 3 primary measures of myelosuppression (ie, hemoglobin levels, platelet counts, and neutrophil counts) before each cycle of chemotherapy in patients with and without a BRCA mutation. RESULTS: We included 130 BRCA mutation carriers and 302 noncarriers who met the eligibility criteria. There were no significant differences in baseline hemoglobin levels, neutrophil counts, or platelet counts between the groups (P >= 0.31). We found no significant difference in 3 measures of hematologic toxicity (ie, neutropenia, anemia, or thrombocytopenia) based on BRCA mutation status across all chemotherapy cycles (P >= 0.06). Although BRCA mutation carriers were more likely to experience an absolute neutrophil count below 1.0 * 10/L than noncarriers (P = 0.02), this did not translate to an increased frequency of dose reduction or dose delay. DISCUSSION: Among women with ovarian cancer, hematologic toxicity does not appear to be more frequent in BRCA mutation carriers than in noncarriers. This is reassuring for clinicians treating ovarian cancer patients with respect to dosing regimens. These findings do not support the hypothesis that a haploinsufficiency phenotype exists with respect to the repair of chemotherapy-induced double-strand DNA breaks in this high-risk population. PMID- 29194192 TI - Sentinel Node Biopsy in Endometrial Cancer With Dual Cervical and Fundal Indocyanine Green Injection. AB - PURPOSE: The aim of this study was describe a novel sentinel lymph node (SLN) tracer injection procedure featuring dual cervical and fundal indocyanine green (ICG) injection for endometrial cancer and results of SLN biopsy. METHODS: Between June 26, 2014 and October 31, 2016, 111 patients underwent laparoscopic surgery for endometrial cancer at our institution. In all cases, we performed SLN biopsy with dual cervical and fundal ICG injection. All SLNs were processed with an ultrastaging technique. A total of 69 patients also underwent total pelvic and paraaortic lymphadenectomy. RESULTS: The detection rates were as follows: 92.79% (103/111) overall for SLNs; 89.19% (99/111) overall for pelvic SLNs; 61.26% (68/111) for bilateral SLNs; 59.46% (66/111) for paraaortic SLNs, and 4% (4/111) for isolated paraaortic SLNs. We found macroscopic lymph node metastasis in 11 patients (9.9%) and microdisease in lymph nodes in another 10 patients, raising the overall rate of lymph node involvement to 18.92%. There was 1 false-negative (negative SLN biopsy but positive aortic lymphadenectomy) and another positive case in 1 undetected SLN. The sensitivity of detection was 94.44%, specificity 100%, negative predictive value 97.83%, and negative likelihood ratio 0.06 for intermediate and high-risk endometrial cancer groups. CONCLUSIONS: The SLN biopsy with both cervical and fundal ICG injection offers good overall detection rates and improved mapping of the aortic area. The SLN ultrastaging increases the number of nodes considered positive. PMID- 29194193 TI - Clinical Predictors of Recurrence and Prognostic Value of Lymph Node Involvement in the Serous Borderline Ovarian Tumor. AB - AIM: This study was aimed to evaluate the risk factors of recurrence and the value of nodal involvement in patients with serous borderline ovarian tumors (SBOT). METHODS: Two hundred twenty-five patients who underwent surgery and were diagnosed with SBOT were retrospectively studied. Univariate and multivariate analyses were used to assess the risk factors for recurrence. Patients' clinical pathologic characteristics were compared between the patients who presented lymph node involvement and those who did not. The significant values of lymph condition influencing 5-year disease-free survival were also evaluated by statistical analysis. RESULTS: Both univariate and multivariate analyses showed that risk factors for recurrence were micropapillary (P = 0.021), fertility-preserving surgery (P = 0.014), and laparoscopic approach (P = 0.009). Of these 112 patients on whom lymphadenectomy was performed, 17 cases showed lymph node positive, whereas the remaining 95 patients did not. Significant differences in terms of lymph node numbers (P < 0.0001), invasive implant (P = 0.022), and International Federation of Gynecology and Obstetrics staging (P < 0.0001) were observed between the 2 groups of lymphatic node involved or not. Kaplan-Meier curves of 5 year disease-free survival revealed that there were no significant differences either between groups of lymphatic node involved or not (P = 0.778) and groups of removed nodes whether more than 10 or not (P = 0.549). CONCLUSIONS: Micropapillary, fertility-preserving, and laparoscopic approach were factors significantly affecting the recurrence of SBOT by both univariate and multivariate analysis. Lymph node metastasis did not seem to be correlated to a worse prognosis of SBOT. PMID- 29194194 TI - Feasibility of Sentinel Node Mapping in Ovarian Tumors: What Is the Evidence? PMID- 29194195 TI - Gene Expression Signature-Based Prediction of Lymph Node Metastasis in Patients With Endometrioid Endometrial Cancer. AB - OBJECTIVE: This study aimed to develop a prediction model for lymph node metastasis using a gene expression signature in patients with endometrioid-type endometrial cancer. METHODS: Newly diagnosed endometrioid-type endometrial cancer cases in which the patients had undergone lymphadenectomy during a surgical staging procedure were identified from a national dataset (N = 330). Clinical and pathologic data were extracted from patient medical records, and gene expression datasets of their tumors were used to create a 12-gene predictive model for lymph node metastasis. We used principal components analysis on a training set (n = 110) to develop multivariate logistic models to predict low-risk patients having a probability of lymph node metastasis of less than 4%. The model with the highest prediction performance was selected for an evaluation set (n = 112), which, in turn, was validated in an independent validation set (n = 108). RESULTS: The model applied to the evaluation set showed 100% sensitivity (90% confidence interval [CI], 74%-100%) and 42% specificity (90% CI, 34%-51%), which resulted in 100% negative predictive value (90% CI, 89%-100%). In the validation set, we confirmed that the model consistently showed 100% sensitivity (90% CI, 88%-100%), 42% specificity (90% CI, 32%-50%), and 100% negative predictive value (90% CI, 88%-100%). CONCLUSIONS: Our 12-gene signature model is a useful tool for the identification of patients with endometrioid-type endometrial cancer at low risk of lymph node metastasis, particularly given that it can be used to analyze histologic tissue before surgery and used to tailor surgical options. PMID- 29194196 TI - Use of Optical Coherence Tomography by Nonexpert Personnel as a Screening Approach for Glaucoma. AB - PURPOSE: This pilot study was conducted to assess optical coherence tomography (OCT) as a screening tool for glaucoma when used by nonexpert personnel. METHODS: This prospective case-control study included 54 patients with open-angle glaucoma and 54 age-matched comparison individuals. Optovue iVue SD-OCT imaging was performed by nonprofessional photographers on undilated patients. The sensitivity, specificity, negative predictive value, and positive predictive value of iVue scan parameters for detecting open-angle glaucoma were evaluated. RESULTS: The iVue cup to disc vertical ratio had a sensitivity of 0.96 [95% confidence interval (CI), 0.90-1.00] at 90% specificity and was strongly correlated with both the Cirrus HD-OCT cup to disc vertical ratio (Pearson coefficient=0.84) and the cup to disc ratio observed on dilated clinical examination by faculty ophthalmologists (Pearson coefficient=0.80). The retinal nerve fiber layer (RNFL) parameters performed robustly, but the ganglion cell complex parameters showed limited diagnostic value. The inferior quadrant thickness was among the best performing RNFL parameters, with a sensitivity of 0.87 (95% CI, 0.78-0.96) and a specificity of 0.88 (95% CI, 0.80-0.97) using the iVue normative database thresholds for abnormality. CONCLUSIONS: OCT imaging may be performed by nonprofessional photographers on undilated patients, and quantitative parameters derived from the resultant images, particularly the vertical cup to disc ratio and the RNFL inferior quadrant thickness, demonstrate sensitivities and specificities that may be adequately robust for glaucoma screening in the community setting. PMID- 29194197 TI - Diurnal Variation of Optical Coherence Tomography Measurements of Static and Dynamic Anterior Segment Parameters. AB - PURPOSE: To examine the diurnal variation of static and dynamic anterior segment parameters in young, healthy eyes by comparing anterior segment optical coherence tomography (AS-OCT) measurements obtained in the morning and evening and also in the light and dark. METHODS: Twenty-two subjects ranging from 19 to 47 years of age with no past ocular history were selected. Imaging was performed with the Tomey CASIA2 AS-OCT device in 2 fixed lighting environments, light and dark, between the hours of 08:30 to 10:00 and 17:30 to 19:00. Four AS-OCT images were analyzed per eye. Pupil diameter (PD), iris area (IA), iris curvature (IC), anterior chamber depth (ACD), lens vault (LV), anterior chamber width (ACW), anterior chamber area (ACA), angle opening distance (AOD), angle recess area (ARA), trabecular iris space area (TISA), and trabecular iris angle (TIA) were measured. RESULTS: Pupil diameter was similar between the AM and PM groups in the light (P=0.89) and dark (P=0.51). There was no significant difference between AM and PM measurement values for any of the static or dynamic parameters in the light (P>0.39) and dark (P>0.31). Intraclass correlation coefficients (ICC) demonstrated excellent agreement between AM and PM measurement values in the light (ICC>0.81) and dark (ICC>0.93). In addition, there was no significant difference between AM and PM angle opening distance at 500 um measurement values in the light (P>0.34) and dark (P>0.40) when each of 8 angle sectors was analyzed individually. CONCLUSIONS: No significant diurnal variation of static or dynamic anterior segment parameter measurements was detected in the light and dark. Diurnal variation of these parameters does not regularly occur in young, healthy eyes. PMID- 29194198 TI - Latanoprostene Bunod 0.024% in Subjects With Open-angle Glaucoma or Ocular Hypertension: Pooled Phase 3 Study Findings. AB - PURPOSE: To compare the diurnal intraocular pressure (IOP)-lowering effect of latanoprostene bunod (LBN) 0.024% with timolol maleate 0.5% in subjects with open angle glaucoma (OAG) or ocular hypertension (OHT). PATIENTS AND METHODS: Pooled analysis of two phase 3, randomized, multicenter, double-masked, parallel-group, noninferiority trials (APOLLO and LUNAR), each with open-label safety extension phases. Adults with OAG or OHT were randomized 2:1 to double-masked treatment with LBN once daily (qd) or timolol twice daily (bid) for 3 months followed by open-label LBN treatment for 3 (LUNAR) or 9 (APOLLO) months. IOP was measured at 8 AM, 12 PM, and 4 PM at week 2, week 6, and months 3, 6, 9, and 12. RESULTS: Of the 840 subjects randomized, 774 (LBN, n=523; timolol crossover to LBN, n=251) completed the efficacy phase, and 738 completed the safety extension phase. Mean IOP was significantly lower with LBN versus timolol at all 9 evaluation timepoints during the efficacy phase (P<0.001). A significantly greater proportion of LBN-treated subjects attained a mean IOP <=18 mm Hg and IOP reduction >=25% from baseline versus timolol-treated subjects (P<0.001). The IOP reduction with LBN was sustained through the safety phase; subjects crossed over from timolol to LBN experienced additional significant IOP lowering (P<=0.009). Both treatments were well tolerated, and there were no safety concerns with long term LBN treatment. CONCLUSIONS: In this pooled analysis of subjects with OAG and OHT, LBN 0.024% qd provided greater IOP-lowering compared with timolol 0.5% bid and maintained lowered IOP through 12 months. LBN demonstrated a safety profile comparable to that of prostaglandin analogs. PMID- 29194199 TI - Evaluation of a Trabecular Microbypass Stent With Cataract Extraction in Severe Primary Open-angle Glaucoma. AB - PURPOSE: To evaluate the safety and efficacy of a trabecular microbypass stent combined with cataract surgery in patients with severe open-angle glaucoma. PATIENTS: The series included 59 eyes with severe primary open-angle glaucoma and severe visual field loss as defined by American Academy of Ophthalmology preferred practice pattern criteria. MATERIALS AND METHODS: Retrospective case series. Patients were implanted with 1 trabecular microbypass stent with concomitant cataract surgery. Primary outcome measures were intraocular pressure (IOP) and number of glaucoma medications. Safety measures included postoperative IOP pressure spikes >=15 mm Hg or IOP<6 mm Hg at any time point, and the need for additional surgery. RESULTS: The mean preoperative IOP was 19.25+/-6.97 mm Hg. Postoperatively, the mean IOP was 14.38+/-3.63 mm Hg (P<0.01) at 12 months and 14.92+/-3.86 mm Hg (P<0.01) at 24 months. The mean number of glaucoma medications was 2.27+/-1.06 preoperatively and 1.63+/-1.17 (P<0.01) at 24 months postoperative, indicating a 28% reduction in medication use. In total, 4 (7%) eyes required additional surgery. In total, 5 eyes (8%) experienced IOP spikes >=15 mm Hg, 14 (24%) eyes had IOP spikes >=10 mm Hg. Overall 55% of eyes had a 20% IOP reduction after 24 months of surgery. Eyes with baseline IOP<=19 had a mean reduction of 2.24 mm Hg 36 months after surgery. CONCLUSIONS: Trabecular microbypass stent implantation during cataract surgery safely and effectively lowers IOP and medication use in patients with severe primary open-angle glaucoma.

PMID- 29194201 TI - Evaluation of Long-term Anatomic Changes Following Canaloplasty With Anterior Segment Spectral-domain Optical Coherence Tomography and Ultrasound Biomicroscopy. AB - BACKGROUND: To analyze long-term structural changes in conjunctiva, sclera and Schlemm canal (SC) with anterior segment optical coherence tomography (AS-OCT) and ultrasound biomicroscopy (UBM) following uncomplicated canaloplasty. MATERIALS AND METHODS: Fifteen patients with planned canaloplasty and no intraoperative complications were included in this prospective study. AS-OCT images were acquired at 1, 3, 6 months and at a long-term time point (20+/-4.9 mo) postsurgery. UBM images were acquired at 3, 6 months and long-term after canaloplasty. The surgical site was evaluated for the presence of SC, transscleral filtration, a scleral lake, and the visibility of intra-Schlemm sutures. The SC's height and width were measured at the 3 and 9 o'clock limbus position. RESULTS: Following canaloplasty, the intraocular pressure was successfully reduced from 23.43+/-5.52 to 12.6+/-1.78 mm Hg (P<0.0001) at the final control visit. Topical medication was reduced from 2.9+/-1.1 to 0.4+/-0.6 over the same period. SC's increase in height was higher than that in width at the last visit (height: +351%, P=0.0004, width: +144%, P=0.002). With the UBM the SC was easily identifiable by the reflection of the tractions sutures in 75% of the patients at the last visit. Transscleral filtration was detectable in 42% of the patients at the last visit using AS-OCT and a scleral lake was still detectable by OCT in 25% of the patients and even in 42% of the patients by UBM. CONCLUSIONS: Persisting anatomic changes of SC, a transscleral filtration and a scleral lake can be recorded by AS-OCT and UBM long-term after successful canaloplasty.

PMID- 29194203 TI - Relationship Between Open-angle Glaucoma and Stroke: A 2010 to 2012 Korea National Health and Nutrition Examination Survey. AB - PURPOSE: To determine the relationship between open-angle glaucoma (OAG) and stroke in the Korean population. MATERIALS AND METHODS: This study was a population-based, cross-sectional study that used data from the Korea National Health and Nutrition Examination Survey (KNHANES), a complex, stratified, multistage, probability-cluster survey. We analyzed a total of 11,959 participants who were above 40 years old and were included in the fifth KNHANES database (2010 to 2012 data). Weighted prevalence of OAG and stroke in various populations were estimated. Univariate and multivariate logistic regressions were performed to examine potential risk factors for stroke, including OAG. Multivariate adjusted odds ratios (OR) for stroke were examined in subjects with and without OAG. Subjects were also examined by hypertension and diabetes status. RESULTS: Stroke patients had a significantly higher OAG prevalence (8.5%) than nonstroke patients (3.8%; P<0.001). After adjusting for selected risk factors, the presence of OAG tended to be associated with stroke (adjusted OR=1.629), but this result was not statistically significant (P=0.053). Stroke and OAG were significantly associated with each other in subjects with hypertension (OR=2.059; P=0.010) and diabetes (OR=2.649; P=0.040). In addition, the associations of stroke and other systemic diseases were stronger when OAG was a comorbid condition. CONCLUSIONS: Although there was no overall statistical significance, patients with OAG had an increased risk of stroke, among those with systemic comorbidities, including hypertension and diabetes. Our results may provide insight on the underlying mechanisms of OAG and their association with stroke development. PMID- 29194204 TI - A Retrospective Review Comparing the Safety and Efficacy of 120 Versus 160 Applications of Selective Laser Trabeculoplasty. AB - PURPOSE: To compare the effectiveness and safety of 120 applications versus 160 applications of selective laser trabeculoplasty (SLT) at reducing intraocular pressure (IOP) from baseline in glaucoma patients over a 1-year period. METHODS: A retrospective chart review was conducted, comprising 376 eyes from 199 patients who underwent SLT treatment performed by the same glaucoma subspecialist from 2014 to 2015. Data were obtained on patients' clinical features, management, and outcomes. Patients were treated with either 120 applications or 160 applications of SLT per 360 degrees of trabecular meshwork over 2 sessions. Statistical analyses were performed comparing baseline IOP with IOP at 6 weeks and 1-year follow-up after completion of treatment. The incidence and severity of transient IOP rises immediately post-SLT was also recorded. RESULTS: Both SLT regimes were effective at reducing IOP. Univariate t tests showed that the 160 applications group had significantly greater mean reduction of IOP from baseline at both 6 weeks (4.6 vs. 3.6 mm Hg, P=0.015) and 1-year time points (4.1 vs. 2.8 mm Hg, P=0.019). However, when multivariate analyses were used to account for the effects of clustering and include other covariates such as age, baseline IOP, history of previous SLT there was no significant difference between success rates of the 2 treatment groups at either time points. Higher baseline IOP was associated with greater IOP reduction at 6 weeks (P<0.001) and 1 year (P<0.001) for both treatment groups. There was no statistical difference in incidence and severity of IOP spikes at 1-hour post-SLT between the 2 treatment groups. CONCLUSIONS: SLT produces a significant IOP-lowering effect and treatment with 160 applications per 360 degrees may be more effective than 120 applications per 360 degrees. Furthermore, 160 applications of SLT does not increase the risk of transient IOP spikes. PMID- 29194205 TI - A Protective Eye Shield Reduces Limbal Strain and Its Variability During Simulated Sleep in Adults With Glaucoma. AB - PURPOSE: To determine the effect of wearing a protective eye shield (mask) on limbal strain magnitude and variability in glaucoma eyes when sleeping with 1 side of the face down (FD) against a pillow. METHODS: A prospective, randomized, interventional trial was conducted at the Wilmer Eye Institute with 36 glaucoma patients. A contact lens sensor measured limbal strain (output in equivalent millivolts) during intervals of up to 60 minutes in lateral decubitus, FD, and supine positions. Eighteen subjects wore a mask during 1 of 2 FD intervals, with randomized assignment of the interval. Data from additional trials with no mask were included in some analyses. In addition, some facial-feature dimensions from 3D scanned images of 23 subjects were compared with limbal strain data. RESULTS: Wearing a mask trends toward a reduced mean change in contact lens sensor output (limbal strain) on moving to a FD positions [+34.1 mVeq, P=0.01 reduced by -22.3 mVeq, P=0.09 (n=36)]. Mask wearing reduced variability in strain while FD [-22.8 mVeq, P=0.04 (n=18)]. In eyes with past progressive visual field loss, the effect of the mask reduced mean strain change when moving to FD [-44.8 mVeq, P=0.02 (n=31)]. Longer corneal apex to nose-tip and to temple lengths were associated with reduced variability while FD [P=0.02 and 0.04, respectively (n=23)]. Treating both lengths as confounding factors increased statistical significance, particularly for analysis of the no-mask change in strain data moving to and from the FD position [P=0.004 to 0.002 and P=0.03 to 0.01 (n=23)]. CONCLUSION AND RELEVANCE: Wearing a mask reduced limbal strain and variation in limbal strain during simulated FD sleep, particularly in eyes with past field worsening, as did some facial features. PMID- 29194206 TI - Predictive Factors for Visual Field Conversion: Comparison of Scanning Laser Polarimetry and Optical Coherence Tomography. AB - PURPOSE: The purpose of this study was to compare the ability of scanning laser polarimetry (SLP) and spectral-domain optical coherence tomography (SD-OCT) to predict future visual field conversion of subjects with ocular hypertension and early glaucoma. METHODS: All patients were recruited from the Erlangen glaucoma registry and examined using standard automated perimetry, 24-hour intraocular pressure profile, and optic disc photography. Peripapillary retinal nerve fiber layer thickness (RNFL) measurements were obtained by SLP (GDx-VCC) and SD-OCT (Spectralis OCT). Positive and negative predictive values (PPV, NPV) were calculated for morphologic parameters of SLP and SD-OCT. Kaplan-Meier survival curves were plotted and log-rank tests were performed to compare the survival distributions. Contingency tables and Venn-diagrams were calculated to compare the predictive ability. RESULTS: The study included 207 patients-75 with ocular hypertension, 85 with early glaucoma, and 47 controls. Median follow-up was 4.5 years. A total of 29 patients (14.0%) developed visual field conversion during follow-up. SLP temporal-inferior RNFL [0.667; 95% confidence interval (CI), 0.281 0.935] and SD-OCT temporal-inferior RNFL (0.571; 95% CI, 0.317-0.802) achieved the highest PPV; nerve fiber indicator (0.923; 95% CI, 0.876-0.957) and SD-OCT mean (0.898; 95% CI, 0.847-0.937) achieved the highest NPV of all investigated parameters. The Kaplan-Meier curves confirmed significantly higher survival for subjects within normal limits of measurements of both devices (P<0.001). Venn diagrams tested with McNemar test statistics showed no significant difference for PPV (P=0.219) or NPV (P=0.678). CONCLUSIONS: Both GDx-VCC and SD-OCT demonstrate comparable results in predicting future visual field conversion if taking typical scans for GDx-VCC. In addition, the likelihood ratios suggest that GDx-VCC's nerve fiber indicator<30 may be the most useful parameter to confirm future nonconversion.

AB - OBJECTIVES: 1) Describe publishing trends for otologic/neurotologic disorders over a 35-year span. 2) Compare trends in publishing with disease prevalence. 3) Evaluate changes in topic and journal specific ranking scores over time. METHODS: PubMed searches were performed on 35 otologic/neurotologic disorders using medical subject headings (MeSH) terms from 1980 to 2015. Searches were limited in scope to the English language. A Mann-Kendall trend analysis evaluated changes in publication frequency as a discrete variable while correcting for total number of articles published per year. Scopus was used to identify SCImago Country and Journal Rank (SJR) indicator scores and weighted-averages used to calculate changes over time. RESULTS: The total number of publications on the 35 topics increased from 853 in 1980 to a peak of 3,068 in 2013. Otitis media (tau = 0.799, p < 0.001) and Meniere's disease (tau = -0.724, p < 0.001) showed strong decreasing publication trends. Temporal bone encephaloceles (tau = 0.743, p < 0.001) and cochlear implants (tau = 0.740, p < 0.001) showed strong increasing publication trends. Rapid rise in publications on superior canal dehiscence and vestibular migraine illustrate novel diagnoses. The weighted-average SJR score increased from 0.816 in 2000 to 1.160 in 2015 (p < 0.001). CONCLUSION: This study displays trends in the literature over the past 35 years that are often inconsistent with common disorders seen by otologists/neurotologists. Certain diagnoses that are currently being researched less commonly continue to impact patients with the same regularity. Quality of otologic/neurotologic literature has become more reputable with regards to SJR scores. PMID- 29194213 TI - Ollier Disease of the Lateral Skull Base. PMID- 29194212 TI - Evaluation of Mitoquinone for Protecting Against Amikacin-Induced Ototoxicity in Guinea Pigs. AB - HYPOTHESIS: Mitoquinone (MitoQ) attenuates amikacin ototoxicity in guinea pigs. BACKGROUND: MitoQ, a mitochondria-targeted derivative of the antioxidant ubiquinone, has improved bioavailability and demonstrated safety in humans. Thus, MitoQ is a promising therapeutic approach for protecting against amikacin-induced ototoxicity. METHODS: Both oral and subcutaneous administrations of MitoQ were tested. Amikacin-treated guinea pigs (n = 12-18 per group) received water alone (control) or MitoQ 30 mg/l-supplemented drinking water; or injected subcutaneously with 3 to 5 mg/kg MitoQ or saline (control). Auditory brainstem responses and distortion product otoacoustic emissions were measured before MitoQ or control solution administration and after amikacin injections. Cochlear hair cell damage was assessed using scanning electron microscopy and Western blotting. RESULTS: With oral administration, animals that received 30 mg/l MitoQ had better hearing than controls at only 24 kHz at 3-week (p = 0.017) and 6-week (p = 0.027) post-amikacin. With subcutaneous administration, MitoQ-injected guinea pigs had better hearing than controls at only 24 kHz, 2-week post-amikacin (p = 0.013). Distortion product otoacoustic emission (DPOAE) amplitudes were decreased after amikacin injections, but were not different between treatments (p > 0.05). Electron microscopy showed minor difference in outer hair cell loss between treatments. Western blotting demonstrated limited attenuation of oxidative stress in the cochlea of MitoQ-supplemented guinea pigs. CONCLUSIONS: Oral or subcutaneous MitoQ provided limited protection against amikacin-induced hearing loss and cochlear damage in guinea pigs. Other strategies for attenuating aminoglycoside-induced ototoxicity should be explored. PMID- 29194214 TI - Prediction of Vestibular Imbalance in Acute Peripheral Vestibulopathy by Measuring Horizontal Ocular Deviation on Magnetic Resonance Imaging. AB - OBJECTIVES: The aim of the study is to evaluate whether horizontal ocular deviation (OD) from MR imaging in the emergency room (ER) reflects vestibular imbalance, by comparing the horizontal OD in patients with acute vestibulopathy to controls. STUDY DESIGN: Retrospective review. PATIENTS AND METHODS: A total of 69 patients with acute unilateral peripheral vestibulopathy and 30 healthy subjects were included. Horizontal OD was quantified by using the axial T2 weighted fast-spin echo (FSE) images of the brain at 1.5 T. In the study group, the results of VFTs (videonystagmography [VNG], caloric test, rotary chair test, and cervical vestibular evoked myogenic potentials [cVEMP]) were also reviewed. The averaged angle of right and left horizontal ODs was compared between patients with acute unilateral vestibulopathy and healthy controls. Also, the correlation between horizontal OD and results of VFTs was analyzed in the study group. RESULTS: The averaged angle of horizontal OD in study group (23.7 degrees +/- 11.6 degrees ) was significantly greater than that of control group (4.27 degrees +/- 3.7 degrees ) (p < 0.05). Horizontal OD significantly correlated with slow phase velocity of spontaneous nystagmus (SN), the value of caloric paresis (CP) on caloric testing, rotary chair gain, asymmetry ratio of rotary chair test and interaural difference (IAD) of cVEMP, regardless of time intervals between magnetic resonance imaging (MRI) and VFTs. CONCLUSIONS: Horizontal OD significantly correlated with parameters of VFT which reflect the vestibular imbalance. Therefore, horizontal OD can be used as an indicator of unilateral peripheral vestibular weakness. PMID- 29194215 TI - Cochlear Implant Insertion Axis Into the Basal Turn: A Critical Factor in Electrode Array Translocation. AB - HYPOTHESIS: An inappropriate insertion axis leads to intracochlear trauma during cochlear implantation (CI). BACKGROUND: Few studies assessed the relationship between the insertion axis and the electrode scalar location. METHODS: Preimplantation cone-beam CT (CBCT) was performed on 12 human temporal bones. In five temporal bones, an optimal insertion axis was planned, due to the impossibility to attain the ST centerline from the posterior tympanotomy, because of facial canal position. In the seven other temporal bones, an inaccurate insertion axis was intentionally planned (optimal axis+15 degrees). Automated CI array insertion according to the planned axis was performed with a motorized insertion tool driven by a navigated robot-based arm. The cochlea and basilar membrane were segmented from the preimplantation CBCT and the array segmented from the postimplantation CBCT to construct a merged final three-dimensional (3D) model. Microscopical and 3D analysis were performed to determine the intracochlear trauma at the level of each electrode. RESULTS: A good agreement was observed in determining electrode position between microscopic analysis and the 3D model (Cohen's kappa k = 0.67). The angle of approach to the ST centerline was associated with the number of electrodes inserted into the ST (r = -0.65, p = 0.02, [95% CI -0.90 to -0.11] Spearman's rank correlation). CONCLUSION: A 3D reconstruction model was effective in determining the array position in the cochlea scalae. Our data indicate that the angle of approach to the ST centerline is a critical factor in intracochlear trauma. Additional studies should be conducted to assess the importance of the insertion axis with other array designs. PMID- 29194216 TI - Gastrostomy Tubes: Care and Feeding.

PMID- 29194222 TI - Risk Factors for Admission and Prolonged Length of Stay in Pediatric Isolated Skull Fractures. AB - OBJECTIVES: This study aimed to assess management of pediatric isolated skull fracture (ISF) patients by determining frequency of admission and describing characteristics associated with patients admitted for observation compared with patients discharged directly from the emergency department (ED) and those requiring a prolonged hospitalization. METHODS: We evaluated children younger than 5 years who presented with ISF using the South Carolina Traumatic Brain Injury Surveillance and Registry System data from 2001 to 2011. Outcomes analyzed included discharged from ED, admitted for less than 24 hours, and admitted for more than 24 hours (prolonged hospitalization). Bivariate analyses and a polytomous logistic regression model identified factors associated with patient disposition. RESULTS: Five hundred twenty-seven patients met the study criteria (ED discharge = 283 [53%]; inpatient <24 hours = 156 [29%]; inpatient >24 hours = 88 [18%]). The mean length of stay for admissions was 1.9 (SD, 1.5) days. In the regression model, ED discharges had greater odds of presenting to levels 2 to 3 hospitals (level 2: odds ratio [OR], 6.16; 95% confidence interval [CI], 3.66 10.39; level 3: OR, 30.98; 95% CI, 10.92-87.91) and lower odds of a high poverty status (OR, 0.20; 95% CI, 0.10-0.40). Prolonged hospitalizations had greater odds of concomitant injuries (OR, 2.21; 95% CI, 1.12-4.36). CONCLUSIONS: Admission after ISF is high despite a low risk of deterioration. High-poverty patients presenting to high-acuity medical centers are more commonly admitted for observation. Only presence of concomitant injuries was clinically predictive of prolonged hospitalization. The ability to better stratify risk after pediatric ISF would help providers make more informed decisions regarding ED disposition. PMID- 29194224 TI - A Population Based Analysis of Melanoma of the External Ear. AB - OBJECTIVE: Malignant melanoma accounts for nearly 75% of all skin cancer deaths, and the incidence is on the rise in the United States. External ear melanoma (EEM) is rare, and there is little long-term data regarding the clinical behavior of this melanoma site. This study analyzes the demographic, clinicopathologic, and survival characteristics of EEM. METHODS: The SEER database was queried for EEM cases from 1973 to 2012 (8,982 cases). Data analyzed included patient demographics, incidence trends, and survival outcomes. RESULTS: External ear melanoma occurred most frequently in the sixth and seventh decades of life. Mean age at diagnosis was 65.5 (+/-16.8) years. However, the incidence of EEM in adolescents and young adults (ages 15-39 yr) has increased by 111.9% from 1973 to 2012. There was a strong male predilection with a male-to-female ratio of 6.40:1. The most common histologic subtype was malignant melanoma, NOS (46.8%), followed by superficial spreading melanoma (21.4%), and lentigo maligna melanoma (17.9%). The majority of cases were localized at the time of presentation (88.0%), with rare distant metastasis (1.9%). The most common treatment modality was surgery alone (97.6%), followed by surgery with radiotherapy (2.3%). Ten-year disease specific survival was better among those treated with surgery alone (90.7%), than those treated with surgery with radiotherapy (37.1%) (p < 0.0001). Increasing Breslow's thickness and presence of an ulcerating lesion were both associated with poorer survival (p < 0.0001). CONCLUSION: This study represents the largest cohort of EEM. It has an excellent survival outcome with surgery being the treatment of choice. PMID- 29194225 TI - Hearing Outcomes After Stereotactic Radiosurgery for Jugular Paraganglioma. AB - OBJECTIVE: To describe audiometric outcomes following stereotactic radiosurgery (SRS) for jugular paraganglioma (JP). STUDY DESIGN: Retrospective review. SETTING: Tertiary referral center. PATIENTS: Patients with pretreatment serviceable hearing (American Academy of Otolaryngology-Head and Neck Surgery [AAO-HNS] Class A or B) and serial post-SRS audiometric follow-up who underwent Gamma Knife SRS for JP between 1990 and 2017. INTERVENTION(S): Gamma Knife SRS. MAIN OUTCOME MEASURES: Progression to nonserviceable hearing; correlation between baseline hearing and treatment parameters with audiometric outcomes. RESULTS: Of 85 patients with JP who underwent SRS during the study period, 35 (66% female, median age 53) had pretreatment serviceable hearing and serial post-treatment audiometry available for review. Median tumor volume at the time of treatment was 7,080 mm, median cochlear point dose was 5.8 Gy (interquartile range [IQR] 4.1 to 7.3 Gy), and median marginal and maximum tumor doses were 16 and 32 Gy, respectively. After a median follow-up of 37 months (IQR 16 to 77 mo), the median change in pure-tone average and speech discrimination score in the treated ear was -1.2 dB HL/yr (IQR -4.5 to 0.3) and 0%/yr (IQR 0-3.5%), compared with 0.07 dB HL/yr (IQR -0.03 to 0.12) and 0 %/yr (IQR 0 to 0%) in the contralateral untreated ear. Seven patients developed nonserviceable hearing (AAO-HNS Class C or D) at a median of 13.2 months following SRS (IQR 4.8 to 24 mo). Among those who maintained serviceable hearing, median audiometric follow-up was 42 months (IQR 18 to 77 mo). The Kaplan-Meier estimated rates of serviceable hearing at 1, 3, and 5 years following SRS were 91%, 80%, and 80%, respectively. Sixty percent of patients with pulsatile tinnitus who underwent SRS experienced varying levels of symptomatic improvement following treatment. CONCLUSION: The short- and intermediate-term risk of progression to nonserviceable hearing following SRS for JP is low. Data regarding the impact of cochlear dose from the vestibular schwannoma literature should not be freely applied to JP, since the impact of SRS parameters on hearing preservation seems to be less significant.

PATIENTS: Thirty-one ears in 30 patients aged 65 years and older were included and matched with 31 controls, based on the type of surgery, of a pool of 133 patients aged 35 to 55 years. INTERVENTION: Therapeutic. MAIN OUTCOME MEASURE: Success was defined as tympanic membrane closure and resolution of presenting complaints. Complications were assessed. Frailty was defined by assessing multimorbidity and polypharmacy. Fisher's exact test was used to compare success and complication rates between the age groups. Linear logistic regression analysis using generalized linear models was performed on success and complication rate. RESULTS: Success rates in both the groups were 84%. Complication rate in the elderly group was 16% versus 6% in the control group. This difference was not statistically significant in the Fisher's exact test. In the generalized linear model analysis age group, multimorbidity and polypharmacy had no significant influence on both success and complication rate. CONCLUSION: There was no difference in success and complication rate in elderly undergoing tympanoplasty compared with younger adults. Having multimorbidity or polypharmacy did not correlate with failure of the tympanic membrane closure or a higher complication rate. PMID- 29194227 TI - Oesophageal or transgastric views for estimating mean pulmonary artery pressure with transoesophageal echocardiography: A prospective observational study. AB - BACKGROUND: Recent data suggest that in cardiac surgical patients, the pulmonary artery acceleration time (PAT) is useful for estimating mean pulmonary artery pressure (MPAP) noninvasively with transoesophageal echocardiography (TOE). The pulmonary valve can be visualised from multiple echocardiographic windows, but it is unclear which, if any, view correlates best with MPAP. OBJECTIVE(S): To compare the PAT measured with TOE from oesophageal and transgastric views with MPAP obtained invasively with a pulmonary artery catheter. DESIGN: A prospective observational study. SETTING: St. Vincent's Hospital, Melbourne, a university tertiary referral centre in Australia. PATIENTS: Sixty-three patients having cardiac surgery were included in our study. All patients had insertion of both a TOE probe and pulmonary artery catheter; this is the routine standard of care in our centre. INTERVENTION(S): Nil. MAIN OUTCOME MEASURES: During a period of haemodynamic stability, the PAT was measured first from an oesophageal view and then immediately after from a transgastric view. The results were then compared with the invasively measured MPAP. RESULTS: Simultaneous measurements of MPAP and PAT were taken in 63 patients. In two patients, these measurements were not possible in the transgastric position due to an inability to visualise the right ventricular outflow tract and pulmonary valve. A Bland-Altman analysis of the PAT measured from the upper oesophageal and transgastric views showed a mean difference of 1 ms and limits of agreement of -18 to 16 ms. The area under the receiver operating curves for predicting pulmonary hypertension with PAT were upper oesophageal view 0.99 [95% confidence interval (CI), 0.98 to 1.00] and transgastric view 0.99 (95% CI, 0.97 to 1.00). The agreement between the results from these two views in the diagnosis of pulmonary hypertension (defined as PAT < 107 ms) was 93.4% with a kappa of 0.85 (95% CI, 0.59 to 1.00). There is an inverse curvilinear relationship between PAT and MPAP. Using a cut-off of 107 ms, the upper oesophageal view predicted pulmonary hypertension (defined as MPAP > 25 mmHg) with a sensitivity of 94.7% and specificity of 97.6%. The transgastric view predicted pulmonary hypertension with a sensitivity of 89.4% and specificity of 95.2%. CONCLUSION: Oesophageal and transgastric measurements of PAT have close agreement and a similar high ability to discriminate between people with and without pulmonary hypertension. The transgastric measurement was unobtainable in a small percentage of patients and required more probe manipulation. We would recommend PAT measurement in the upper oesophageal view.

AB - SIGNIFICANCE: This article is the first to investigate the nature of medication cost discussions between ophthalmologists and glaucoma patients. Only 87 of the 275 office visits analyzed had a discussion of medication cost. Providers should consider discussing medication cost with patients to identify potential cost related barriers to medication use. PURPOSE: Glaucoma is an incurable chronic eye disease affecting a growing portion of the aging population. Some of the most commonly utilized treatments require lifelong use, requiring high patient adherence to ensure effectiveness. There are numerous barriers to glaucoma treatment adherence in the literature, including cost. The aim of this secondary analysis was to describe the frequency and nature of patient-physician communication regarding medication cost during glaucoma office visits. METHODS: This was a mixed-methods secondary analysis of video-recorded participant office visits (n = 275) from a larger observational study of glaucoma communication. We analyzed medical information, demographic characteristics, and interviewer administrated questionnaires, as well as verbatim transcripts of interviews. RESULTS: Only 87 participants discussed medication cost during their glaucoma office visit. The majority of the subjects who discussed cost had mild disease severity (51%), took one glaucoma medication (63%), and had Medicare (49%) as well as a form of prescription insurance (78%). The majority of glaucoma office visits did not discuss medication cost, and providers often did not ask about cost problems. Of the few conversations related to cost, most focused on providers offering potential solutions (n = 50), medical and prescription service coverage (n = 41), and brand or generic medication choices (n = 41). CONCLUSIONS: Our findings are similar to previous studies showing few patients have conversations with providers about the cost of glaucoma medications. Providers should consider bringing up medication cost during glaucoma office visits to prompt a discussion of potential cost-related barriers to medication use.

AB - BACKGROUND: Several fibrosis-related factors influence liver stiffness measurements (LSM); however, these changes have not been investigated in the context of the various disease stages of chronic hepatitis B (CHB). AIM: The aim of this study was to assess the correlations between fibrosis-related factors and LSM in different disease stages of CHB. PATIENTS AND METHODS: Patients with mild CHB (n=305) and cirrhotic hepatitis B (cirrhotic HB) (n=137) were compared with determine the relationship between LSM and fibrosis-related factors including parameters of liver inflammation [aminotransferase (ALT), aspartate transaminase (AST), total bilirubin (Tbil)], albumin, globulin, peripheral blood cells (neutrophil granulocytes, red blood cells, platelets), abdominal ultrasound B scan parameters including right liver thickness, portal vein inradium, diameter of spleen (DS), thickness of spleen (TS), and splenic vein inradium (SV). RESULTS: In patients with mild CHB, LSM was correlated strongly with ALT (r=0.3534, P<0.0001), AST (r=0.3976, P<0.0001), and ALT+AST (r=0.3760, P<0.0001). LSM was correlated closely with Tbil (r=0.2237, P<0.0001), albumin (r=-0.3126, P<0.0001), albumin/globulin (r=-0.3086, P<0.0001), SV (r=0.3317, P<0.0001), DS (r=0.4157, P<0.0001), and spleen volume (DS*TS) (r=-0.4399, P<0.0001). Red blood cells were correlated negatively with LSM in both mild CHB and cirrhotic HB patients (r=-0.1981, P=0.0203; r=-0.1593, P=0.0053). LSM was not correlated with age, peripheral blood cell parameters, right liver thickness, portal vein inradium, or TS in mild CHB or cirrhosis HB patients. However, in patients with cirrhotic HB, LSM values were not correlated significantly with other fibrosis related factors, except for Tbil (r=0.2272, P=0.0076). CONCLUSION: Our findings suggest that the magnitude of these correlations differs significantly between mild CHB and cirrhotic HB patients. PMID- 29194233 TI - Quality of life related to oral, subcutaneous, and intravenous biologic treatment of inflammatory bowel disease: a time trade-off study. AB - OBJECTIVES: Novel oral treatments (including biologics) of inflammatory bowel disease (IBD) are emerging. Apart from improvement of health, treatment convenience may be of value to patients. This 'process utility' can be estimated under the quality-of-life framework. We investigated the process utility associated with subcutaneous and intravenous biologic treatments compared with a hypothetical oral biologic treatment of IBD. MATERIALS AND METHODS: A time trade off study to estimate utilities for health states among adult patients with IBD was carried out. Respondents rated the anchor state (no description of the route of administration; the reference) and three states described: the once-daily oral, 2-weekly subcutaneous, and 8-weekly intravenous administration of biologic treatment for advanced IBD. RESULTS: Data from 127 respondents (age, 34.4 years; women, 52.9%) were collected. The oral state was valuated higher than the anchor state more frequently than subcutaneous and intravenous states (P=0.001). The process utility of the oral state adjusted for confounders was estimated at 0.147 (95% confidence interval: 0.087-0.208) and 0.164 (95% confidence interval: 0.096 0.233) in comparison with subcutaneous and intravenous states, respectively. The results were consistent across the respondents irrespective of their characteristics and unaffected by the change in the assumptions of data analysis. CONCLUSION: Oral administration is preferred over the available routes of administration of biologics by patients with IBD. The utility gains from oral treatment were significant, indicating higher value of that treatment within a cost-utilitarian approach. The additional process-related benefit can justify higher expenditures for the research of oral biologics. PMID- 29194234 TI - Beyond Admission: Enrollment Management.

PMID- 29194237 TI - Will BSN Students Consider a Future Nursing Faculty Role? AB - AIM: The aim of the study was to determine the intent of baccalaureate nursing students to pursue a future nursing faculty role. BACKGROUND: An impending nursing faculty shortage negatively affects the capacity to meet the need for nurses. METHOD: Using the constructs of social cognitive career theory, a prospective correlational research design was used to survey prelicensure BSN nursing students regarding their intent for a future nursing faculty role. RESULTS: Twenty-five percent of the students intend to pursue a future faculty role. The six statistically significant predictors for a future faculty role were type of nursing program (OR = 2.0), interest in the activities of a faculty role (OR = 2.3), outcome expectations-advantages (OR = 1.9), previous teaching experiences (OR = 1.7), encouragement (OR = 1.5), and outcome expectations disadvantages (OR = 0.8). CONCLUSION: Providing students with knowledge of the faculty role, teaching experiences, and encouragement may inspire them to pursue a future faculty role. PMID- 29194238 TI - The Effect of a Formal Mentoring Program on Career Satisfaction and Intent to Stay in the Faculty Role for Novice Nurse Faculty. AB - AIM: The purpose of this mixed-method study was to explore the influence of a formal mentoring program on career satisfaction of novice full-time nurse faculty in academia. BACKGROUND: The transition from the role of clinician to faculty in an academic setting can be challenging for novice nurse faculty. METHOD: A link to an electronic survey with open-ended questions was emailed to 1435 participants. RESULTS: The response rate was 17.6 percent (N = 124). Mean scores were obtained, and independent t-test were computed to compare scores of faculty who had participated in a mentoring program with scores of nonparticipants. Content analysis of the open-ended answers was conducted, and common themes were identified. CONCLUSION: By examining characteristics that contribute to the success of novice nursing faculty, recruitment and retention of faculty may improve, which is essential due to the worsening nursing faculty shortage. PMID- 29194239 TI - Traditional and Accelerated Baccalaureate Nursing Students' Self-Efficacy for Interprofessional Learning. AB - AIM: The aim of the study was to examine self-efficacy among traditional and accelerated nursing students with regard to interprofessional learning. BACKGROUND: The World Health Organization and other organizations recognize the need for interprofessional education to prepare health care providers for collaborative practice. Graduates of baccalaureate nursing programs require competence in interprofessional collaboration and communication. METHOD: Traditional (n = 239) and accelerated (n = 114) nursing students' self-efficacy was measured utilizing Mann et al.'s Self-Efficacy for Interprofessional Experiential Learning Scale. RESULTS: Accelerated students averaged significantly higher than traditional students on the interprofessional team evaluation and feedback subscale (p = .006) and overall self-efficacy (p = .041). CONCLUSION: Awareness of possible differences between traditional and accelerated nursing students with regard to self-efficacy may help faculty develop effective interprofessional learning experiences for students in each cohort. Although results cannot be generalized, findings from this study provide evidence to guide the selection of learning strategies. PMID- 29194240 TI - A Literature Review of Research on What Has Become of Accelerated Second-Degree Baccalaureate Nursing Graduates. AB - BACKGROUND: Accelerated second-degree baccalaureate nursing (ASDBN) programs have become popular in the United States as a solution to meet the demand for BSN nurses. The research conducted on ASDBN graduates is limited and focuses on educational experience or early career outcomes, such as NCLEX-RN pass rates or first-year job performance. AIM: This research is designed to provide a better understanding of the status of ASDBN graduates two years after completion of the BSN program. METHOD: A literature review was conducted focusing on research into ASDBN graduates beyond their student experiences or early significant career events or outcomes. RESULTS: Surprisingly, only two articles met the interest criteria used in this literature review. CONCLUSION: There are clear and significant gaps in areas that examine ASDBN graduates beyond the immediate postgraduation period. PMID- 29194241 TI - Nursing Student Perceptions of Structural Empowerment. AB - To meet role expectations for nurses, nurses must feel empowered. Faculty contributions to the learning environment for nursing students are critical. A descriptive analysis of student perceptions of empowerment within the learning environment was conducted using a form of Kanter's Conditions of Work Effectiveness Questionnaire; 203 participants from schools in 17 different states completed surveys. Subjects demonstrated moderate degrees of structural empowerment in their learning environment. This positive finding can be further investigated and used to fully prepare future nurses. PMID- 29194242 TI - Experiential Teaching Increases Medication Calculation Accuracy Among Baccalaureate Nursing Students. AB - Safe medication administration is an international goal. Calculation errors cause patient harm despite education. The research purpose was to evaluate the effectiveness of an experiential teaching strategy to reduce errors in a sample of 78 baccalaureate nursing students at a Northeastern college. A pretest posttest design with random assignment into equal-sized groups was used. The experiential strategy was more effective than the traditional method (t = -0.312, df = 37, p = .004, 95% CI) with a reduction in calculation errors. Evaluations of error type and teaching strategies are indicated to facilitate course and program changes. PMID- 29194243 TI - Simulation in an Undergraduate Nursing Pharmacology Course: A Pilot Study.

PMID- 29194252 TI - Cranioplasty With Mandibular Outer Cortex Bone Grafts. AB - BACKGROUND: Autologous bone grafts are still the best materials for calvarial reconstruction. In the past, rib, iliac crest, and cranial bone have been used for the reconstruction of the calvarial defects. However, the use of mandibular outer cortex bone graft in calvarial defects reconstruction is poorly reported in literature. This study focused on using the mandibular outer cortex bone grafts for calvarial defects. METHODS: From October 2004 to July 2016, there were a total of 13 patients in this study who underwent cranioplasty with mandibular outer cortex bone grafts to reconstruction calvarial defects. All the patients were followed up for at least 6 months. RESULTS: The majority of the patients were satisfied with the reconstructive outcome. CONCLUSION: The authors consider the mandibular outer cortex bone graft can achieve excellent esthetic results in selected cranioplasty reconstructions. PMID- 29194253 TI - Temporal Flap as an Option for Buconasal Fistula Closure. AB - Maxillary defects with buconasal/businusal communications are situations difficult to manage and solve. Several treatment options are available on the literature, each one with its indication. Temporal muscle flap is one of these options, being a technique that requires more experience of the surgeon to be properly performed and that is mainly indicated for difficult cases, large defects and those nonresponsive to simpler techniques. The main purpose of this paper is to report 3 clinical patients of the application of the temporal muscle flap for the closure of extensive oral defects. None of the patients had necrosis, nervous deficits, or any long-term changes. The authors conclude that the use of this flap was shown to be a viable, safe technique with low complication and high success rates, which may contribute to the rehabilitation of well-indicated patients. PMID- 29194254 TI - Anterior Skull Base Tumors: The Role of Transfacial Approaches in the Endoscopic Era. AB - The basis of craniofacial tumor surgery is complete surgical extirpation, preferably en bloc or with free borders. Craniofacial techniques are the gold standard and primary strategies in the treatment of anterior skull base tumors. In the last decade, the reports favoring results of endoscopic techniques have increased. One could conclude that the classical transfacial approaches might become useless, but, in fact, there is little research comparing these techniques.In this article, the authors present their experience with combined craniofacial resection of anterior craniofacial skull base tumors in 9 consecutive patients between January 2013 and July 2015. This article aims to review some of the traditional transfacial approaches, illustrating them with this series of surgical patients. Benefits and drawbacks of these approaches are discussed.

PMID- 29194256 TI - Repair of the Nasal Floor by the Cleft Margin Flap in Bilateral Complete Cleft Lip. AB - Bilateral complete cleft lip deformity has been the most challenging to plastic surgeons, and lots of methods of repair have been described in the literature. The basic principles are to achieve continuity of the orbicularis oris muscle, a balanced Cupid's bow with nasal ala, and a complete reconstruction of the nasal floor. The last one is, however, easily neglected. A well-reconstructed nasal floor serves as a good support of the nasal cartilage, which minimizes secondary deformity. In addition, a nasal floor with sufficient soft tissue and minimal contracture makes bone grafting easier in the future. The cleft margin flap was first introduced by Tajima in 1983 and used for the nasal floor repair in the unilateral complete cleft lip. The authors have used this technique in bilateral complete cleft lip repair, and from our practice, tension-free repairs of the nasal floors could easily be achieved by the cleft margin flaps. The results were satisfying and no significant scar contracture or deformity of the nasal floor was observed during follow-up. The authors conclude that the cleft margin flaps are viable and alternative choices for the repair of the nasal floors in bilateral complete cleft lip without major complications. PMID- 29194257 TI - Clinical Significance of Biofilm on Silicone Tubes Removed From Patients With Nasolacrimal Duct Stenosis. AB - PURPOSE: To determine the relationship between the optical density of biofilms on silicone tubes and surgical outcomes. METHODS: A total of 43 silicone tubes from 33 patients with nasolacrimal duct stenosis were enrolled at 6 months after bicanalicular silicone tube intubation. The removed silicone tubes were divided into 2 segments. One segment of silicone tube was cultured while the other segment was used to measure optical density of biofilm. Each segment was divided into 3 pieces according to average normal human nasolacrimal anatomy. The first piece was located from puncta to lacrimal sac. The second piece was inside the nasolacrimal duct. The third piece was in the nasal cavity. Surgical outcome was evaluated at postoperative 12 months based on Munk score and fluorescein dye disappearance test. RESULTS: A total of 31 (72.1%) patients were surgically successful while 12 (27.9%) patients had surgical failure with persistent epiphora. In the second piece of silicone tube, the mean optical density of biofilm was 0.2654 nm in the surgical success group and 0.4472 nm in the surgical failure group. These results showed statistically significant (P < 0.01) difference. The most frequently isolated organism was Staphylococcus aureus in the surgical success group (7 of 31 patients, 22.6%). It was Pseudomonas aeruginosa in the surgical failure group (6 of 12 patients, 50%). CONCLUSION: This is the first study that determines the relationship between biofilm on silicone tube and surgical outcome. Biofilm formed on silicone tubes in nasolacrimal duct might cause surgical failure. PMID- 29194258 TI - Management of Nonsyndromic Skeletal Dysgnathia by Distraction Osteogenesis Long Term Follow-Up. AB - Distraction osteogenesis has been a paradigm shift in the field of orthognathic surgery. Majority of the published cases are those of syndromic patients that have been managed using varying treatment protocols. This communication describes a patient of 18-year-old male diagnosed with skeletal Class II malocclusion due to mandibular retognathism. The patient was taken up for mandibular corpus distraction of 10 mm. By this approach the patient was benefitted with good esthetic result and functional occlusion. Distraction protocol followed in this patient for lengthening of mandibular corpus has resulted in a stable outcome. The 2-year follow-up photographs show a stable result both esthetically and functionally. PMID- 29194259 TI - A Clinical Photographic Method to Evaluate the Need for Helmet Therapy in Deformational Plagiocephaly. AB - PURPOSE: With an increase in positional plagiocephaly patients, various therapy methods have been researched and helmet therapy is the most widely used and effective treatment method. To devise a method that would allow medical professionals and patients' parents to more easily identify the shape and outcomes before and after the therapy. METHODS: This study included 399 patients who had helmet therapy from November 2014 to February 2016. Patients wore a cast helmet for more than 20 hours per day. A cranial caliper was used to measure their head before they wore the helmet (prehelmet), once a month during outpatient visits, and 6 months after they stopped wearing the helmet (posthelmet). Clinical photographs were taken on a transparent acrylic sheet with a grid of 5-mm intervals to measure cranial vault asymmetry (CVA), cranial vault asymmetry index (CVAI), and symmetry ration (SR). The patients' photographs were then measured twice: first against the background without the grid and then against the background with the grid. RESULTS: Average age at prehelmet was 20 weeks while their average therapy period was 12 weeks. Patients' prehelmet CVA was 13.3 mm, and their posthelmet CVA was 3.1 mm. Their prehelmet CVAI was 10.1%, and their posthelmet CVAI was 2.1% (P < 0.001). Their overall prehelmet and posthelmet SRs were 0.820 and 0.969, respectively (P < 0.001). In addition, the measurements based on clinical photographs with and without the grid were compared using Fleiss kappa. The results showed kappa = 0.847 and 0.956 when the patient was mild, kappa = 0.744 and 0.919 when it was moderate, and kappa = 0.767 and 0.924 when it was severe (P < 0.001). In all 3 patients, the consistency was higher with the grid. CONCLUSION: Since cast helmet manufacturing for positional plagiocephaly therapy does not require computed tomography scanning, there is no need to administer a sedative, nor does it pose any radiation exposure risk. Since the cast helmet is easier to manufacture and operate and is more cost effective, it could be used to treat more people. In addition, it would be useful for both medical professionals and patients' guardians to use clinical photographs with the acrylic sheet with the grid as a method to analyze shapes and outcomes before and after therapy, along with traditional CVA and CVAI. PMID- 29194260 TI - Facial Anthropometric Evaluation of Unilateral Cleft Lip and Palate Patients: Infancy Through Adolescence. AB - INTRODUCTION: Craniofacial anthropometric studies measure the differences in humans' craniofacial dimensions. The aim of this study was to determine facial anthropometric dimensions of newborn to 12-year-old girls with nonsyndromic unilateral cleft lip and palate (UCLP). METHODS: In this cross-sectional analytical study, data was collected from 65 infant to 12-year old girls with UCLP. Digital frontal and profile facial photographs were transferred to a computer and desired anthropometric landmarks were traced on each image. Fifteen anthropometric parameters were measured which were the angles of facial, nasofacial, nasomental, Z, nasolabial, inclination of nasal base and labial fissure, nasal deviation, mentocervical, facial convexity and also ratios of nasal prominence relative to nasal height, middle to lower facial third, upper lip to lower lip height, columellar length relative to upper lip, and incisal show relative to incisal width. Pearson coefficient and linear regression were used for statistical analysis. RESULTS: Upper lip to lower lip height ratio and angles of nasofacial, nasolabial, and facial convexity decreased with the age of the patients. In contrast, nasomental angle and the ratios of columellar length to upper lip length, middle facial height to lower facial height, and incisal show relative to incisal width increased. Other parameters studied did not appear to have any significant correlation with age. CONCLUSION: In the girls with UCLP, various craniofacial dimensions have different growth rates with some parts growing slower than others. Some of the parameters studied were significantly correlated with age, thus growth-related curves and equations were obtained and presented. PMID- 29194262 TI - Application of YL-1 Needle in Chronic Subdural Hematoma Treatment for Super-Aged Patients. AB - OBJECTIVE: The proportion of the super-aged population (at the age of 80 or above) in patients with chronic subdural hematoma (CSDH) and the incidence of CSDH of the population have been increasing. Since it is widely accepted that YL 1 needle is effective in CSDH treatment, this paper aimed to probe into the efficacy of YL-1 needle in minimally invasive surgery for super-aged (at the age of 80-90) CSDH patients. METHODS: A retrospective analysis on the clinical information of 17 super-aged CSDH patients having received the YL-1 needle puncture treatment provided by the hospital from May 2012 to December 2016 was performed. At the same time, another 19 CSDH patients (ages 60-79) who were hospitalized during the same period were randomly selected to form a control group. The same surgical treatment was provided for both groups to observe and compare the treatment efficacy. RESULTS: The patients of both groups were cured and discharged. Among the super-aged patients, there was 1 patient with postoperative hematoma recurrence, 1 patient with pneumocephalus, and 1 patient with wound infection; among the aged patients, 1 reported postoperative recurrence and 2 had pneumocephalus; The average length of stay of the super-aged group was 9.235 +/- 2.948 days while that of the aged group was 7.316 +/- 3.660 days, which showed no statistical difference. CONCLUSION: The YL-1 needle puncture treatment is safe and efficacious for both the super-aged and the aged CSDH patients. PMID- 29194263 TI - The Value of a Photobook in Informing Families About the Cosmetic Results of Surgery in Craniosynostosis. AB - This paper outlines the development and evaluation of a photobook resource to support parents' decision making regarding potential craniofacial surgery for their child. The photobook was developed at a UK Craniofacial Unit and consisted of preoperative and postoperative photographs of patients with craniosynostosis. It was intended to act as a visual adjunct to detailed verbal discussion of surgical treatment options. No changes in the uptake rate of surgery were detected following the introduction of the photobook.

PMID- 29194264 TI - Navigation-Assisted Nasal Bone Osteotomy for Malunited Fracture. AB - BACKGROUND: Nasal bone osteotomy subjectively judges the position for osteotomy by visual inspection and by manual feel using the fingertip. Therefore, the outcome depends on the surgeon's experience and mastery of the procedure is technically challenging. METHODS: The authors applied a navigation system for the intraoperative evaluation of the osteotomy line and reduction position in 5 patients with malunited nasal bone fracture. The authors performed the operation with a temporal bone post developed for otologic surgery using Stealth Station S7 System (Medtronic, Minneapolis, MN). The suretrack is attached to the bone chisel. The authors performed the osteotomies while visualizing the tip of the chisel on the monitor.In addition, evaluation of the reduction position was performed by insertion of a 23G needle syringe with the suretrack to the nasal bone surface. RESULTS: The tip of the bone chisel was visible on the monitor, and the authors could perform osteotomies while confirming the position and direction of osteotomy. In addition, the reduction position could be visualized clearly on the monitor. CONCLUSION: Navigation systems can confirm the 3-dimensional spatial relationship around the fracture site in real time, requiring only comparatively simple preoperative preparation and intraoperative operation without radiation exposure. Therefore, the advantage is that even an inexperienced surgeon can perform an accurate evaluation. This would be useful as a guide for young doctors and medical students as it would be possible to perform safe and accurate osteotomy for old nasal bone fractures. PMID- 29194265 TI - Computed Tomographic Artifacts in Maxillofacial Surgery. AB - OBJECTIVES: The present study aimed to present 4 cases and to undertake a systematic review on the current knowledge of the impact of cone beam computed tomographic (CBCT) artifacts on oral and maxillofacial surgical planning and follow-up. METHODS: The MEDLINE (PubMed) database was searched for the period from February 2004 to February 2017, for studies on the impact of CBCT artifacts on surgical planning of oral and maxillofacial surgeries. The PRISMA statement was followed during data assessment and extraction. As a result, data extraction included information regarding: the use of CBCT to plan or follow-up oral and maxillofacial surgeries, presence and type identification of a CBCT artifact, and details on the impact of artifacts on image quality and/or surgical planning. Four cases were selected to illustrate the topic. RESULTS: The search strategy yielded 408 publications in MEDLINE (PubMed). An initial screening of the publications was performed using abstracts and key words. After application of exclusion criteria, a total of 11 studies were finally identified as eligible to be discussed. Studies revealed 3 main types of artifact: beam hardening, streak, and motion artifacts. Most of the studies suggest that artifacts significantly affect oral and maxillofacial surgical planning and follow-up, despite of allowing for identification of metal projectiles in cases of maxillofacial trauma. CONCLUSION: CBCT artifacts have a significant impact on oral and maxillofacial surgical planning and follow-up. PMID- 29194266 TI - Total Cheek Reconstruction Using the Pre-Expanded Medial Arm Flap With Functional and Aesthetic Donor Site Closure. AB - This clinical study aimed at introducing a reconstructive method for total cheek soft tissue defects using the pre-expanded medial arm flap and to maximally reduce donor site morbidities simultaneously. A retrospective review of data was performed for 3 patients requiring the pre-expanded medial arm flap to reconstruct total cheek defects. The donor site in the medial arm was primarily closed using a pedicle parascapular or thoracodorsal artery perforator flap. All patients had a total unilateral cheek defect after lesion removal. Three pre expanded medial arm flaps measuring 17 * 11 cm, 22 * 15 cm, and 20 * 15 cm were separately used for cheek defect reconstruction. The donor sites in the medial arm were closed using a pedicle parascapular flap, measuring 22 * 9.5 cm, and 2 pedicle thoracodorsal artery perforator flaps, measuring 22 * 10 cm and 23 * 10 cm. No major complications occurred in any patient. Patients were followed up for 3, 12, and 18 months. Patients (and/or their family members) were satisfied with the final outcomes. Total cheek defect reconstruction using a pre-expanded medial arm flap, with the donor site closed using a pedicle axial back flap, can not only provide sufficient tissue for cheek resurfacing, but also guarantee primary donor site closure and could be an alternative reconstructive option for patients who have a total cheek defect. PMID- 29194267 TI - Evaluating of Platelet-Rich Fibrin in the Treatment of Alveolar Cleft With Iliac Bone Graft By Means of Volumetric Analysis. AB - The purpose of this study was to evaluate the efficiency of platelet-rich fibrin usage in the treatment of alveolar cleft with iliac bone graft by means of volumetric analysis. In this study, 22 patients with alveolar clefts-including 13 unilateral and 9 bilateral-were treated with anterior iliac crest bone grafts. Patients were divided into 2 groups as control (group A) and platelet-rich fibrin (group B) groups. Cone beam computed tomography (CBCT) scans were obtained preoperatively and 6 months postoperatively. Three-dimensional reconstructions of CBCT images were created by using Mimics software. Preoperative alveolar cleft volume and postoperative newly formed bone volume were assessed volumetrically. The percentages of preoperative alveolar cleft volume ranged from 0.51 to 2.04 cm, with a mean volume of 0.98 +/- 0.33 cm. The percentages of newly formed bone in group B ranged from 50.70% to 80.09%, with a mean percentage of 68.21 +/- 10.80%. In Group A, the percentages of bone formation ranged from 47.02% to 79.23%, with a mean percentage of 64.62 +/- 9.49%. Platelet-rich fibrin can be used in the treatment of alveolar cleft with corticocancellous bone graft harvested from the anterior iliac crest, but in this study, there was no statistically significant difference between the groups for postoperative newly formed bone volume (P > 0.05). PMID- 29194268 TI - Rapid Anterior Segmental Maxillary Retraction by Compression Osteogenesis. AB - Maxillary protrusion is one of the deformities of the upper jaw. Orthodontics and orthodontics combined with anterior segmental osteotomy are the common treatment strategies for this deformity. The hypothesis of this study was that the maxillary bone segment could be gradually moved backward safely by using a tooth borne-specific compression device that causes bone compression at the bony segment interface after performance of surgical bone cuts in cases of anterior maxillary protrusion. Ten patients with skeletal maxillary protrusion were treated by modified subapical maxillary osteotomy. Then the protrusion was gradually set back and fixed in a new position through the use of a compression device. After 8 weeks, the device was removed, and soft and hard tissue was evaluated. The average setback of the anterior maxillary segment was found to be 6.8 mm. The ratio of the upper lip to the maxillary incisor retraction was 0.52:1. The nasolabial angle increased with a change of 13.5 degrees . The mentolabial angle increased with a change of 12.5 degrees . This study is the first clinical study in using compression osteogenesis aided by a modified anterior subapical maxillary osteotomy technique in the management of skeletal maxillary protrusion that considered as an alternative to traditional surgical methods and to avoid its complications. It can be used successfully and safely, leading to rapid maximum setback of the anterior maxillary segment with great contact between bone segment, better and gradual hard and soft tissue remodeling, short treatment duration, and avoid using plates and screws with its complications. PMID- 29194269 TI - Bibliometric Analysis of Journals in the Field of Endoscopic Endonasal Surgery for Pituitary Adenomas. AB - Endoscopic endonasal surgery for pituitary adenomas is being performed more frequently worldwide in the recent years. This first bibliometric analysis was conducted aiming to have a microscopic view of research activities about endoscopic endonasal surgery for pituitary adenomas. The original articles about endoscopic endonasal surgery for pituitary adenomas were extracted from the Web of Science (WoS) and analyzed concerning their distributions. We also explored the potential correlations between publications of different countries and their gross domestic product (GDP) via Pearson correlation test. The total number of original articles retrieved from WoS was 307 from 1997 to 2017. The number of original articles published in the last decade has increased by 530.95% compared with that published in the former decade. The United States has published 124 articles (40.391%), followed by Italy with 40 (13.029%) and Japan with 27 articles (8.795%). The journal that published the highest number of original articles was Journal of Neurosurgery with 31 (10.098%), followed by Neurosurgery (n = 23, 7.492%), World Neurosurgery (n = 23, 7.492%), and Neurosurgical Focus (n = 15, 4.886%). There was a strong correlation between publication numbers and GDP of different countries (r = 0.889, P < 0.001). There is a skyrocket trend of endoscopic endonasal surgery for pituitary adenomas during the last 2 decades, and countries with high GDP tend to make more contributions to this field. PMID- 29194271 TI - Severe Retrobulbar Pain in an Undiagnosed Patient of Atypical Fracture of Sphenozygomatic Region. PMID- 29194270 TI - Trend and Demographic Characteristics of Maxillofacial Fractures in Level I Trauma Center. AB - AIM: The aim of this study was to analyze the pattern and treatment of craniomaxillofacial injuries in the northern part of Israel, within a Jewish majority and large Arab minority population. PATIENTS AND METHODS: A 5-year retrospective study evaluated patients treated for craniomaxillofacial fractures. Fracture cause, type, site, and patient demographics were evaluated. RESULTS: Patient age ranged from 1 to 94 years with an average age of 36.7 years; 52% of the victims were Jews and 48% Arabs. There was male predilection in both sectors (78.3% vs 21.7%). The main site of injury was the zygomatic bone (33.5%) followed by nasal bone, orbital, mandible, frontal sinus, and maxillary fractures. The main etiology of injuries was falls (45.4%) with significantly more falls reported by females (52.1% vs 43.2% in males). Motor vehicle accidents caused injuries more frequent in males. Arabs experienced CMF fractures at a younger age compared to Jews (27.8 and 44.8 average age, respectively). In the elderly, the trend reversed where Jews were more prone to craniomaxillofacial fractures. CONCLUSIONS: Compared to their weight in the population, the Arab sector experiences more craniomaxillofacial injuries. The Jewish elderly population tends to reside in nursing homes where they are more susceptible to accidental falls, whereas young Arab males are more exposed to motor vehicle accidents and interpersonal violence. Falls were the main cause of injuries particularly in women. This may reflect the women's fear of reporting domestic violence. We believe that increased government investments in infrastructures and education will lower the incidence of craniomaxillofacial trauma and balance the gap between both sectors and sexes. PMID- 29194272 TI - Comparison of Complication Rate Between LeFort III and Monobloc Advancement With or Without Distraction Osteogenesis. AB - BACKGROUND: LeFort III osteotomies or monobloc advancements, with or without distraction, can be used to treat mid-facial hypoplasia causing exorbitism and obstructive sleep apnea in syndromic patients. This report is a meta-analysis of the complication rates following LeFort III osteotomies or monobloc advancement with or without distraction. METHODS: Triple database search was conducted to identify articles addressing mid-facial hypoplasia treated with LeFort III or monobloc in which complications were detailed. Complications were considered major if they required a second operation or were potentially life threatening. Statistical analysis was performed with Student t test. RESULTS: Fifteen studies fit inclusion criteria. This yielded 363 total patients. In patients treated with a monobloc advancement, there was a statistically higher rate of major (P < 0.0001) and minor (P < 0.0001) complications, death (P = 0.02), cerebrospinal fluid (CSF) leaks (P < 0.0001), and meningitis/abscess (P < 0.0001) when distraction was used. In patients treated with a LeFort III, there was a statistically higher rate of reoperation when distraction was used (P = 0.001). In patients treated without distraction, there was a statistically higher rate of major (P < 0.0001) complications, death (P = 0.008), CSF leaks (P = 0.003), and reoperation (P < 0.0001) with a monobloc and a statistically higher rate of minor complications (P < 0.001) with a LeFort III. CONCLUSION: LeFort III proved to be a safer technique for the treatment of mid-facial hypoplasia. Although distraction was initially introduced to reduce complications, in this review, monobloc with distraction had the highest rate of major complications. There are multiple confounding factors that influence success of mid-face surgery and every patient must be evaluated and treated individually. PMID- 29194273 TI - Is Osteoplasty With Unilateral Osteotomy Effective in the Correction of the Crooked Nose? AB - OBJECTIVE: The crooked nose is frequently observed, and a significant number of correction methods have previously been described. Nevertheless, the condition remains a challenging problem for rhinoplastic surgeons. Here, the authors present a technique that the authors have used to correct a crooked nose in selected patients. METHODS: A total of 23 patients underwent surgery for a C shaped crooked nose, and were followed up for an average of 11.4 months. Pre- and postoperative photographs were taken, and these were analyzed to evaluate the results. RESULTS: Osteoplasty and unilateral osteotomy were carried out in all 23 patients and a spreader graft was contralaterally placed. Unilateral osteoplasty was conducted in 17 patients, while bilateral osteoplasty was performed in 6 patients. In 19 patients, a single spreader graft was sufficient, but it was necessary to use a double spreader graft in 4 patients. In summary, 23 C-shaped crooked noses were corrected with osteoplasty plus unilateral osteotomy. CONCLUSIONS: Osteoplasty plus unilateral osteotomy, combined with a contralateral spreader graft, is an efficient method that can be safely used in the correction of a C-shaped crooked nose. PMID- 29194274 TI - A Stratified Algorithm for Skull Base Reconstruction With Endoscopic Endonasal Approach. AB - The authors presented our institutional experience with skull base reconstruction techniques and developed a stratified algorithm for different causes of cerebrospinal fluid (CSF) leak. This is a retrospective review of patients who were diagnosed as CSF leak treated with skull base reconstruction or who underwent endoscopic transsphenoidal surgery for sellar and parasellar lesions at our department from August 2012 to April 2017. The authors totally identified 57 (59 operations in total) patients who were divided into 3 groups according to the causes of CSF leak and different reconstruction techniques. All patients underwent skull base reconstruction with specific focus on diagnosis, reconstruction techniques and strategies, and clinical outcome. The reconstruction technique we adopted was the classical multiple-layer technique, as known as "sandwich" technique, with combination of fat tissue, septal bone, autologous fascia lata, artificial dura, and nasoseptal flap (NSF). The NSF was selectively harvested for large defects according to our protocol. The reconstruction failure rate is 4.4% (2 of 45) in patients underwent endoscopic surgery for sellar and parasellar lesions. Reconstruction for postoperative iatrogenic, traumatic, and spontaneous CSF leak achieved 100% success rate; 54.2% (32 of 59) operations were done with "sandwich" plus NSF. The overall failure rate of all reconstructions was 3.4% (2 of 59). A stratified approach with multiple-layer technique and NSF is reliable for skull base reconstruction. PMID- 29194275 TI - Preoperative Exposure of Sigmoid Sinus Trajectory in Posterolateral Cranial Base Approaches Using a New Landmark Through a Neurosurgical Perspective. AB - The location of burr holes in posterolateral cranial base approaches should be appropriate to provide an adequate operative field, and surgical freedom is crucial for bone window opening. The aim of this study was to search for more convenient and easily detectable landmarks in comparison with current landmarks in posterolateral cranial base surgery. Twenty 3-dimensional reconstructed head and neck computed tomography angiography images (group 1) and 20 cadaver heads (group 2) were evaluated. An imaginary line connecting the angle of the mandible and the mastoid tip was extended upward. A second line passing through the lateral edge of the zygomatic arch was also extended posteriorly. The authors examined if the first line met with the sigmoid sinus throughout its course and determined the location of the intersection point of these 2 lines relative to the sigmoid-transverse sinus junction. The intersection point did not correspond to the sinus region in 3 images from group 1 and 4 specimens from group 2. The matching of the mandibula-mastoid line trajectory with the sigmoid sinus course was unacceptable in 4 images and 5 cadavers. For venous anatomy preservation and anatomic skull base fossa orientation during posterolateral cranial base approaches, upward extension of the mandibula-mastoid line can be a proper landmark for surgical planning in this region. The authors' proposed superficial anatomical line and intersection point over the skull could be used as a reliable indicator for the external projection of the sigmoid sinus and an appropriate initial burr-hole location. PMID- 29194276 TI - Modified Backward Avulsion Used in the Treatment of Third-Branch Primary Trigeminal Neuralgia. AB - OBJECTIVE: A clinical retrospective study was performed to observe the clinical effect of a modified surgical treatment for third-branch primary trigeminal neuralgia. METHOD: Thirty patients who had suffered from neuralgia for several years underwent modified backward avulsion of the inferior alveolar nerve and were followed for 3 to 5 years. In this technique, the inferior alveolar nerve was cut off through the mandibular wisdom tooth extraction socket or the corresponding alveolar ridge window and was avulsed from the mental foramen. Simultaneously, the neural foramen was packed with autogenous bone fragments to prevent recurrence. RESULTS: After a 3- to 5-years follow-up, 19 patients were cured, 8 patients reported a partial effect of treatment, and 3 patients exhibited recurrence. The efficacy rate was 90%. Postoperatively, the patients had different degrees of numbness in the area innervated by the third branch of the trigeminal nerve but did not have any other complications. CONCLUSIONS: This study proved that modified backward avulsion is a simple, effective, and safe method that can be applied in the clinical setting to treat third-branch primary trigeminal neuralgia. PMID- 29194278 TI - Craniosynostosis Surgery and the Impact of Tranexamic Acid Dosing. AB - Consensus does not exist regarding the best dosage regimen for using tranexamic acid (TXA) for patients undergoing open calvarial vault remodeling in craniosynostosis surgery. The purpose of this study was to evaluate 2 dosing protocols, as well as the cost of using TXA. Previously, the institutional protocol was to give patients undergoing open calvarial vault remodeling a loading infusion of TXA (10 mg/kg) at the start of their procedure, after which intravenous TXA (5 mg/kg/h) was given throughout surgery and for 24 hours postoperatively. In July 2015, the protocol changed to a reduced postoperative infusion time of 4 hours. A retrospective review was conducted of records of 30 patients who had surgery before the protocol change (24-hour group) and 23 patients whose surgery occurred after the protocol change (4-hour group). The following data were collected: blood volume transfused, hemoglobin levels, estimated blood loss, and intensive care days; and costs of TXA and blood transfusion. Results showed a 4-hour infusion was as effective as a 24-hour infusion for reducing blood loss in patients undergoing craniosynostosis. Transfusion requirements, hemoglobin and hematocrit levels, and estimated blood loss were not significantly different for the groups. The cost of TXA and transfusion in the 4-hour group was significantly less (P < 0.001) than in the 24 hour group. No significant difference in cost existed for patients who received blood transfusion alone versus patients who received the 4-hour TXA infusion. PMID- 29194279 TI - Cutaneous Metastases of the Glioma. AB - Low grade glioma (LGG) is a very common primary brain neoplasm with a very good prognosis and the median survival of patients is approximately 8 years. With the development of current treatments such as surgery resection, radiotherapy, and chemotherapy, the recurrence rate and the distant metastasis rate of LGGs are largely decreased. Extracranial metastases are seldom happened. However, the authors present a pathologically proven patient with scalp metastasis, which was metastasized from LGG occurring site to the surgical scar 8 months following initial craniotomy and chemotherapy. The histopathologic examination of the primary site and the recurrent under the scalp are exactly similar. This grade of glioma was increased along with cutaneous metastases. A discussion of a series of the extracranial metastases of the glioma, especially for the surgical considerations, is also provided advice for the cutaneous metastases of the glioma. PMID- 29194280 TI - Conization and healthcare use: a population-based register study. AB - The aim of this study was to assess whether negative psychological consequences of conization reported in questionnaire studies translated into increased use of the healthcare services that could relieve such symptoms. This was a population based register study comparing women undergoing conization with a control group of women with normal cytology results. Data were derived from Danish registers. Using the difference-in-differences method, we measured contacts with general practitioners (GPs), hospitals, psychiatrist/psychologists, and use of anxiolytic and antidepressant prescription drugs over 5 years 'before' and 'after' the conization in the study group, and in comparable periods in the control group. During the 'before' period, women who later had a conization had greater contact with GPs and hospitals, and slightly more contact with psychiatrist/psychologists, than control women. In both groups, healthcare use increased significantly from the 'before' to the 'after' period. For contacts with GPs and hospitals, the increase was significantly larger for the conization group than for the control group, but this could be attributed to the standard postconization follow-up process. In the 'before' period, women who later had a conization used fewer drugs than women of the control-group, but their drug use increased similarly over time. The conization event did not result in an increased use of the healthcare services that could relieve potential negative side effects. However, women who underwent a conization seemed to constitute a select group as they already used GPs and hospitals more frequently, and anxiolytic and antidepressant drugs less frequently, than other women in the years 'before' the conization event.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 29194282 TI - Frequency and Characterization of Tracheal Intubation Adverse Events in Pediatric Sepsis. AB - OBJECTIVES: Intubation in critically ill pediatric patients is associated with approximately 20% rate of adverse events, but rates in the high-risk condition of sepsis are unknown. Our objectives were to describe the frequency and characteristics of tracheal intubation adverse events in pediatric sepsis. DESIGN: Retrospective cohort study of a sepsis registry. SETTING: Two tertiary care academic emergency departments and four affiliated urgent cares within a single children's hospital health system. PATIENTS: Children 60 days and older to 18 years and younger who required nonelective intubation within 24 hours of emergency department arrival. Exclusion criteria included elective intubation, intubation prior to emergency department arrival, presence of tracheostomy, or missing intubation chart data. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: The outcome was tracheal intubation adverse event as defined by the National Emergency Airway Registry Tool 4 KIDS. During the study period, 118 of 2,395 registry patients met inclusion criteria; 100% of intubations were successful. First attempt success rate was 57% (95% CI, 48-65%); 59% were intubated in the emergency department, and 28% were intubated in the PICU. First attempts were by a resident (30%), a fellow (42%), attending (6%), and anesthesiologist (13%). Tracheal intubation adverse events were reported in 61 (43%; 95% 43-61%) intubations with severe tracheal intubation adverse events in 22 (17%; 95 CI, 13-27%) intubations. Hypotension was the most common severe event (n = 20 [17%]) with 14 novel occurrences during intubation. Mainstem bronchial intubation was the most common nonsevere event (n = 28 [24%]). Residents, advanced practice providers, and general pediatricians in urgent care settings had the lowest rates of first-pass success. CONCLUSIONS: The rates of tracheal intubation adverse events in this study are higher than in nonelective pediatric intubations in all conditions and highlight the high-risk nature of intubations in pediatric sepsis. Further research is needed to identify optimal practices for intubation in pediatric sepsis. PMID- 29194281 TI - RBC Transfusions Are Associated With Prolonged Mechanical Ventilation in Pediatric Acute Respiratory Distress Syndrome. AB - OBJECTIVES: Blood products are often transfused in critically ill children, although recent studies have recognized their potential for harm. Translatability to pediatric acute respiratory distress syndrome is unknown given that hypoxemia has excluded pediatric acute respiratory distress syndrome patients from clinical trials. We aimed to determine whether an association exists between blood product transfusion and survival or duration of ventilation in pediatric acute respiratory distress syndrome. DESIGN: Retrospective analysis of prospectively enrolled cohort. SETTING: Large, academic PICU. PATIENTS: Invasively ventilated children meeting Berlin Acute Respiratory Distress Syndrome and Pediatric Acute Lung Injury Consensus Conference Pediatric Acute Respiratory Distress Syndrome criteria from 2011 to 2015. INTERVENTIONS: We recorded transfusion of RBC, fresh frozen plasma, and platelets within the first 3 days of pediatric acute respiratory distress syndrome onset. Each product was tested for independent association with survival (Cox) and duration of mechanical ventilation (competing risk regression with extubation as primary outcome and death as competing risk). A sensitivity analysis using 1:1 propensity matching was also performed. MEASUREMENTS AND MAIN RESULTS: Of 357 pediatric acute respiratory distress syndrome patients, 155 (43%) received RBC, 82 (23%) received fresh frozen plasma, and 92 (26%) received platelets. Patients who received RBC, fresh frozen plasma, or platelets had higher severity of illness score, lower PaO2/FIO2, and were more often immunocompromised (all p < 0.05). Patients who received RBC, fresh frozen plasma, or platelets had worse survival and longer duration of ventilation by univariate analysis (all p < 0.05). After multivariate adjustment for above confounders, no blood product was associated with survival. After adjustment for the same confounders, RBC were associated with decreased probability of extubation (subdistribution hazard ratio, 0.65; 95% CI, 0.51-0.83). The association between RBC and prolonged ventilation was confirmed in propensity matched subgroup analysis. CONCLUSIONS: RBC transfusion was independently associated with longer duration of mechanical ventilation in pediatric acute respiratory distress syndrome. Hemoglobin transfusion thresholds should be tested specifically within pediatric acute respiratory distress syndrome to establish whether a more restrictive transfusion strategy would improve outcomes. PMID- 29194283 TI - Cosmetic Adolescent Filler: An Innovative Treatment of the "Selfie" Complex. AB - PURPOSE: "Selfie" photography is increasing among teenagers, accentuates congenital anomalies, and impacts self-confidence. Tear trough deformity is most commonly due to aging, but also occurs as a congenital anomaly and can be a major source of insecurity and embarrassment. OBJECTIVE: The purpose of this study is to show the efficacy and safety of hyaluronic acid gel filler in a teenage patient with congenital tear trough deformity. MATERIAL AND METHOD: We describe the case of a teenager who underwent hyaluronic acid gel filling to the tear trough deformity at age 14 years. Prospective follow up was assessed for 5 years. RESULTS: The patient improved clinical appearance and self confidence. Her satisfaction level was high, and no complication occurred during entire follow up. CONCLUSION: In this case, hyaluronic gel acid filler was safe and effective for augmentation of congenital tear trough. The patient was satisfied and experienced increased self-esteem. PMID- 29194284 TI - Koebner Phenomenon Triggered by External Dacryocystorhinostomy Scar in a Patient With Psoriasis: A Case Report and Literature Review. AB - Koebner phenomenon is the development of isomorphic pathologic lesions on a wound of a patient with preexisting cutaneous disease, most commonly psoriasis. An elderly male with palmoplantar psoriasis developed periocular psoriasis in the form of blepharitis and conjunctivitis following an external dacryocystorhinostomy as a manifestation of Koebner phenomenon. Immediate diagnosis and treatment with topical steroids led to complete recovery. Thus, the authors report the first case of Koebner phenomenon in ophthalmic literature, with a review of previously published postsurgical cases of Koebnerization in psoriasis patients. All surgeons should be aware of its existence and warn susceptible patients regarding its occurrence. PMID- 29194285 TI - Endoscopic Corneal Neurotization: Technique and Initial Experience. AB - PURPOSE: The authors describe a minimally invasive surgical technique to re establish corneal sensibility in a patient with neurotrophic keratopathy with the supraorbital nerve harvested endoscopically. METHODS: Pedicled contralateral supraorbital nerve was harvested endoscopically through small eyelid crease and scalp incisions and transferred to the affected eye. RESULTS: Endoscopic corneal neurotization was successfully performed with restoration of corneal sensibility and corneal epithelial integrity. CONCLUSIONS: The use of an endoscope allows for a minimally invasive approach to successful corneal neurotization with the supraorbital nerve. PMID- 29194286 TI - Desmoplastic Melanoma of the Periorbital Region. AB - Desmoplastic melanoma (DM) is a rare subtype of melanoma and an even smaller proportion of periocular melanomas. Here, the authors report 2 cases of DM in the periocular region. Staged according to the American Joint Committee on Cancer (AJCC) eighth edition classification, patient 1 presented with a stage IIIC (pT4apN1cM0) DM in the left lateral canthus with upper and lower eyelid and patient 2 presented with a stage IIIB (T4aN1bM0) DM in the left brow and supraorbital region with a parotid lymph node metastasis. In both patients, the lesions were amelanotic, with inflammatory appearance, and had been noted for several years before the correct diagnosis was made. In both patients, wide excision led to large surgical defects, and perineural invasion prompted adjuvant radiation therapy postoperatively. Patient 2 was treated with an immune checkpoint inhibitor for his parotid metastasis. Ophthalmologists should be aware of DM, its neurotrophic nature, and potential to metastasize with locally advanced lesions. PMID- 29194287 TI - Expression of ADAMTS2 and ADAMTS5 in the salivary gland of rats after radioiodine therapy. AB - OBJECTIVE: The aim of this study was to investigate the presence of ADAMTS2 and ADAMTS5 in the salivary gland (SG) of rats after high-dose radioiodine therapy. METHODS: A total of 36 male Wistar albino rats were used for this study. Thirty six male rats were divided randomly into six groups: control and five radioactive iodine (RAI) treatment groups of six rats each. All animals were killed. The evaluation of biodistribution and histopathological studies were carried out on the SGs removed. Real-time PCR and immunohistochemical analysis were carried out to determine mRNA and protein expression levels of ADAMTS genes. Differences between the groups were evaluated statistically. RESULTS: In RAI-treated groups, ADAMTS2 and ADAMTS5 gene expression was observed to increase, whereas there was no mRNA or protein expression in the control group. There were statistically significant increases in the mRNA expression of ADAMTS2 (all RAI-administered groups in parathyroid gland and at 4, 24, and 48 h in submandibular gland) and ADAMTS5 (all RAI-administered groups, except on the 30th day in the parathyroid gland and all RAI groups in submandibular gland). Through immunohistochemical analysis, the staining pattern in the extracellular source was also observed in the overexpressed ADAMTS2 and ADAMTS5 groups. Nuclear coarsening and partial focal subnuclei vacuolization were determined in all RAI-administered groups with histopathological examinations. CONCLUSION: An increase in the mRNA expression levels of ADAMTS2 and ADAMTS5 genes was detected in the RAI-administered groups. These results suggested that ADAMTS2 and ADAMTS5 genes might play a role in radiation exposure and radioiodine-induced SG changes. PMID- 29194288 TI - Area at risk can be assessed by iodine-123-meta-iodobenzylguanidine single-photon emission computed tomography after myocardial infarction: a prospective study. AB - BACKGROUND: Myocardial salvage is an important surrogate endpoint to estimate the impact of treatments in patients with ST-segment elevation myocardial infarction (STEMI). AIM: The aim of this study was to evaluate the correlation between cardiac sympathetic denervation area assessed by single-photon emission computed tomography (SPECT) using iodine-123-meta-iodobenzylguanidine (I-MIBG) and myocardial area at risk (AAR) assessed by cardiac magnetic resonance (CMR) (gold standard). PATIENTS AND METHODS: A total of 35 postprimary reperfusion STEMI patients were enrolled prospectively to undergo SPECT using I-MIBG (evaluates cardiac sympathetic denervation) and thallium-201 (evaluates myocardial necrosis), and to undergo CMR imaging using T2-weighted spin-echo turbo inversion recovery for AAR and postgadolinium T1-weighted phase sensitive inversion recovery for scar assessment. RESULTS: I-MIBG imaging showed a wider denervated area (51.1+/-16.0% of left ventricular area) in comparison with the necrosis area on thallium-201 imaging (16.1+/-14.4% of left ventricular area, P<0.0001). CMR and SPECT provided similar evaluation of the transmural necrosis (P=0.10) with a good correlation (R=0.86, P<0.0001). AAR on CMR was not different compared with the denervated area (P=0.23) and was adequately correlated (R=0.56, P=0.0002). Myocardial salvage evaluated by SPECT imaging (mismatch denervated but viable myocardium) was significantly higher than by CMR (P=0.02). CONCLUSION: In patients with STEMI, I-MIBG SPECT, assessing cardiac sympathetic denervation may precisely evaluate the AAR, providing an alternative to CMR for AAR assessment.

AB - BACKGROUND: The number of reports of serious adverse effects and intoxication after the use of the new drug 4-fluoroamphetamine (4-FA) increases. At the Emergency Department of the OLVG-Oost Hospital in Amsterdam, an on-site drug test, the Triage TOX Drug Screen, is available to assist in a rapid diagnosis. In less urgent cases, an EMIT II Plus immunoassay is used to determine semiquantitatively the presence of drugs of abuse (DOA). The antibodies in these immunoassays are designed to detect classic DOA and its urinary metabolites. Amphetamine-like drugs that may cause serious toxicity or impairment may not cross-react with the available immunoassay kits, and therefore may stay undetected. The question arises as to whether 4-FA and paramethoxymethamphetamine (PMMA) are detectable in the toxicological screening procedures commonly used for testing in urine. METHODS: Synthetic urine was spiked with the drug under investigation to create spiking standards of 50, 100, 250, 500, 2500, and 5000 ng/mL. Urine drug screens were performed on the automated analyzer Biosite Triage MeterPro using the Triage TOX Drug Screen test and on a Siemens Drug Testing System Viva-E using the EMIT II Plus Ecstasy Assay and the EMIT II Plus Amphetamines Assay. RESULTS: In this concentration range, the EMIT II Plus did not screen positive for PMMA, but there was some cross-reactivity for PMMA on the EMIT II Plus Ecstasy assay. The Triage TOX Drug Screen did test positive for PMMA at a concentration of 2500 ng/mL. The EMIT II Plus Amphetamines did test positive for 4-FA at a concentration of 5000 ng/mL, whereas the Ecstasy [3,4 methylenedioxymethamphetamine (MDMA)] assay only showed low cross-reactivity for 4-FA. The Triage TOX Drug Screen did not test positive for 4-FA. CONCLUSIONS: The available immunoassays lack sensitivity to detect 4-FA and PMMA in lower urine concentrations. Awareness of the fact that novel DOA may lead to false-negative urinary drug tests is of great importance. PMID- 29194290 TI - Ultrasound Identifies Broken Drainage Tube Postthyroidectomy. AB - Drains are routinely used after thyroidectomy and lateral neck dissection. In rare cases, the drainage tube is broken and retained in the neck. It is difficult to identify the sonographic features of the remnant tube due to variable reasons. However, through comparative and phantom observations, we noticed the double tract sign of the tube wall and drainage holes as the key points to solving this problem. We report such a case of the ultrasound-guided localization of a broken drainage tube that was retained in the patient. PMID- 29194291 TI - The Great Mimicker: Pseudo-Meig Syndrome in a Pregnant Patient. A Review. AB - Meig syndrome is the triad of benign ovarian tumor, ascites, and pleural effusion. Pseudo-Meig syndrome mimics the Meig syndrome triad; however, in pseudo Meig syndrome, the ovarian tumor usually represents a primary malignancy or metastases. Differentiating Meig from pseudo-Meig syndrome is challenging both clinically and with diagnostic imaging but is important because prognoses for these distinct entities are drastically different. Evidence-based sonographic prediction models are valuable because they can aid in this distinction. Here, we present the first reported case of pseudo-Meig syndrome secondary to large, bilateral Krukenberg tumors of unknown origin, in a gravid 30-year-old woman at 24 weeks' gestation, discovered initially by ultrasound. PMID- 29194292 TI - Fetal Splenomegaly: A Review. AB - Enlargement of the fetal spleen is usually found secondary to systemic diseases and is frequently associated with hepatomegaly. By far, the most common causes of fetal splenomegaly are infectious. Other etiologies responsible for this sign are hemolytic anemia, congestive cardiac failure, metabolic disorders, and rarely, leukemia, lymphoma, and histiocytosis.We report a case of prenatal splenomegaly diagnosed at 35 weeks, confirmed in the postnatal period. The postnatal workup showed the newborn had a familial type 3 form of hemophagocytic lymphohistiocytosis (HLH).Hemophagocytic lymphohistiocytosis is an aggressive and life-threatening syndrome of excessive immune activation. The genes implicated in the hereditary forms of the disease act in an autosomal recessive fashion. PMID- 29194293 TI - Multiple pathological mechanisms contribute to hippocampal damage in the experimental autoimmune encephalomyelitis model of multiple sclerosis. AB - Emotional and cognitive deficits and associated hippocampal damage observed in multiple sclerosis (MS) are now recognized as primary disease manifestations. However, the pathological substrate of these dysfunctions is unclear. In the experimental autoimmune encephalomyelitis (EAE) MS model, impaired hippocampal dependent functions are concomitant with severe microglial reactivity and neurodegeneration, but reports vary with respect to evidence of lymphocytic infiltration, raising questions as to the nature of the underlying neurodegenerative mechanisms. Our investigations of EAE-induced inflammation across the hippocampal formation showed CD3 infiltration only in regions adjacent to inflamed meningeal membranes interposed between the ventral aspect of the hippocampus and the dorsal aspect of the mid-brain, but widespread microglial reactivity across the structure. Regions that contact the lateral ventricles do not show inflammation, but CD3 cells are observed in the adjacent ventricular space and choroid plexus, suggesting that microglial reactivity in these regions results from exposure to proinflammatory mediators released into the ventricles. These data indicate that multiple pathophysiological mechanisms underlie hippocampal damage during EAE. Treatment with the immunomodulator FTY720 eliminates microglial reactivity across the whole structure, suggesting potential benefit for neuropsychological symptoms in MS. PMID- 29194294 TI - Task switching following 24 h of total sleep deprivation: a functional MRI study. AB - Task switching is a ubiquitous feature of many human activities that involve multitasking. In addition, owing to occupational demands, many individuals are required to engage in task switching under various levels of sleep deprivation, such as those who work in military and medical contexts. Nevertheless, little is known about the effects that sleep loss has on the neural bases of task switching. To address this shortcoming, we administered a cued switching task to participants following a night of normal sleep and also following a night of total sleep deprivation - in counterbalanced order. The behavioral results demonstrated a cost (i.e. longer reaction time) both as a function of sleep deprivation and task switching. Sleep deprivation resulted in greater activation in the frontoparietal network, whereas task switching was correlated with greater activation in the thalamus and superior temporal gyrus. However, despite increases in fatigue and sleepiness and a reduction in cognitive effectiveness (computed from actigraphic data), the reaction time cost associated with switching (i.e. switch cost) was not exacerbated by sleep deprivation. The results are discussed in terms of the involvement of executive functions in mitigating the effects of sleep deprivation on task switching. PMID- 29194295 TI - The Art of Faculty Searches.

AB - AIM: The aim of the study was to assess entry-level competency and practice readiness of newly graduated nurses. BACKGROUND: Literature on success of new graduates focuses primarily on National Council of State Boards of Nursing Licensure Examination (NCLEX-RN) pass rates, creating a false and incomplete picture of practice readiness. METHOD: Posthire and prestart Performance-Based Development System assessments were administered to more than 5,000 newly graduated nurses at a large midwestern academic medical center between July 2010 and July 2015. RESULTS: Aggregate baseline data indicate that only 23 percent of newly graduated nurses demonstrate entry-level competencies and practice readiness. CONCLUSION: New data suggest that we are losing ground in the quest for entry-level competency. Graduates often are underprepared to operate in the complex field of professional practice where increased patient acuity and decreased length of stay, coupled with a lack of deep learning in our academic nursing programs, have exacerbated a crisis in competency. PMID- 29194298 TI - Establishing Inter- and Intrarater Reliability for High-Stakes Testing Using Simulation. AB - AIM: This article reports one method to develop a standardized training method to establish the inter- and intrarater reliability of a group of raters for high stakes testing. BACKGROUND: Simulation is used increasingly for high-stakes testing, but without research into the development of inter- and intrarater reliability for raters. METHOD: Eleven raters were trained using a standardized methodology. Raters scored 28 student videos over a six-week period. Raters then rescored all videos over a two-day period to establish both intra- and interrater reliability. RESULTS: One rater demonstrated poor intrarater reliability; a second rater failed all students. Kappa statistics improved from the moderate to substantial agreement range with the exclusion of the two outlier raters' scores. CONCLUSION: There may be faculty who, for different reasons, should not be included in high-stakes testing evaluations. All faculty are content experts, but not all are expert evaluators.

AB - AIM: The purpose of the literature review is to evaluate and discuss the various types of academic support programs used for at-risk nursing students to identify those that are most effective. BACKGROUND: Nurse educators are concerned about students admitted to nursing programs who are unable to successfully complete the program. METHOD: To determine the format and efficacy of academic support programs, the literature review addressed the identification of at-risk students and academic support programs applicable to all student groups. RESULTS: Nurse educators need to develop and implement plans to support and retain students in order to address the impending nursing shortage. CONCLUSION: Replacing a student lost to academic failure is difficult. Although utilized in different manners, academic support programs are an effective retention strategy.

AB - BACKGROUND: Living-learning communities have been known to promote student performance and a sense of collegiality. Most studies on this topic have utilized quantitative methods. AIM: This qualitative comparison case study examined personal experiences associated with residing in a living-learning community. The study was conducted to explore findings associated with promoting student retention. A secondary goal was to explore student experiences with mentoring. METHOD: Data were collected using taped recordings of live interviews at two universities that have nursing-themed housing. The targeted sample size was 14. RESULTS: Themes that emerged from the data were mutual support, importance of the resident assistant, and self-determination. CONCLUSION: Nursing students enjoy themed housing and especially desire the resident assistant to be a nursing student. PMID- 29194301 TI - Administrator Perspectives of Advantages and Challenges of Employing Part-Time Faculty in Nursing Education Programs: Two Sides of the Same Coin. AB - AIM: The purpose of this qualitative research was to explore perspectives of administrators (n = 581) regarding advantages and challenges of employing part time nurse faculty (PTNF) in schools of nursing in the United States. BACKGROUND: The nursing faculty shortage has resulted in increased reliance on PTNF who are clinical experts but often inexperienced as educators. A broader evidence base is necessary to develop effective strategies to support and retain these faculty members. METHOD: Deans and directors of schools of nursing were invited to complete an online survey with two open-ended questions about the use of PTNF. RESULTS: Five themes emerged from the qualitative descriptive analysis: clinical practice as primary role, diversity of educational approaches, effects on full time faculty role, economic impact, and contracted educator role. Both positive and negative aspects of each theme were identified. CONCLUSION: Results of this study support specific efforts to provide professional development and support to PTNF.

AB - This study utilized the Lasater Clinical Judgment Rubric (LCJR) to investigate the relationship between the student's self-assessment of clinical judgment skills and the faculty's assessment during a human patient simulation. The study used a quantitative design with baccalaureate nursing students (n = 94) enrolled in an adult health course as participants. The data revealed a positive correlation between evaluator and student scores on the LCJR. The findings support the use of the LCJR in combination with simulation to evaluate nursing students' clinical judgment skills and to quantify competency levels.

AB - Preparing students with opportunities to practice critical thinking skills is essential to success on the National Council Licensure Examination. This pilot study was conducted to explore the effectiveness of turning off practice assessment answers and rationales on a standardized examination. A retrospective study compared students' scores when rationales were turned on and turned off. Eighty-one percent of the students were able to achieve the benchmark when the answers and rationales were turned off as compared to 71 percent when turned on.

AB - The increased anxiety experienced by nursing students during simulations can serve as a significant barrier to learning. The use of anxiety-reducing techniques such as autogenic training (AT) can mitigate the negative effects of anxiety and improve the overall learning experience. The investigators in this study sought to understand the effect of AT on student performance and self efficacy during simulation experiences. The use of AT was an effective technique to decrease anxiety and increase performance among nursing students during nursing simulations. Reducing anxiety during simulations can improve the student learning experience.

AB - Nursing education is challenged to shift from task-based proficiencies to higher level competencies with patient safety as a priority. Using a quasi-experimental pretest/posttest design, a simulation-based, peer-coached, deliberate practice clinical substitution was implemented to compare nursing students' knowledge, skills, and attitudes for promoting safety. Our findings demonstrated improved knowledge and skill acquisition in the intervention and control groups. The former trended toward improved team communication attitudes and enteral medication skill performance. Additional research with larger samples is needed to further investigate this innovative strategy. PMID- 29194306 TI - An Innovative and Successful Simulation Day.

Active participation in social media, on the other hand, was associated with higher exam and final course grades. PMID- 29194309 TI - Care of the Older Adult With Postoperative Delirium: An Interprofessional Simulation for Undergraduate Nursing Students. AB - Because of the expanding older adult population, undergraduate nursing students need to be introduced to the unique challenges of taking care of older adults. Using simulation to demonstrate some of these challenges allows these entry-level students to learn in a nonthreatening environment. By focusing on an older adult patient who is experiencing postoperative delirium in a simulation, students can practice not only how to complete a safety assessment but also effective communication skills with the patient, family, and members of the interprofessional health care team.

AB - BACKGROUND: Hay-hole falls are a prevalent source of trauma among Anabaptists particularly Anabaptist youth. We sought to decrease hay-hole falls in South Central Pennsylvania through the development and distribution of all-weather hay hole covers to members of the at-risk Anabaptist community. METHODS: Following the creation of a rural trauma prevention syndicate, hay-hole cover prototypes co designed and endorsed by the Pennsylvania Amish Safety Committee were developed and distributed throughout South Central Pennsylvania. Preintervention and postintervention surveys were distributed to recipients to gain an understanding of the hay-hole fall problem in this population, to provide insight into the acceptance of the cover within the community, and to determine the efficacy of the cover in preventing falls. RESULTS: A total of 231 hay-hole covers were distributed throughout eight rural trauma-prone counties in Pennsylvania. According to preintervention survey data, 52% of cover recipients reported at least one hay-hole fall on their property, with 46% reporting multiple falls (median fall rate, 1.00 [1.00-2.00] hay-hole falls per respondent). The median self-reported distance from hay-hole to ground floor was 10.0 (8.00-12.0) feet, and the median number of hay-holes present on-property was 3.00 (2.00-4.00) per respondent. Postintervention survey data found 98% compliance with hay-hole cover installation and no subsequent reported hay-hole falls. CONCLUSION: With the support of the Pennsylvania Amish Safety Committee, we developed a well-received hay-hole cover which could effectively reduce fall trauma across other rural communities in the United States.

AB - BACKGROUND: Venous thromboembolism (VTE), including deep venous thrombosis (DVT) and pulmonary embolism (PE), remains a common complication following trauma. The role of hereditary thrombophilia (HT) in posttraumatic VTE is unknown. In the general population with a first-time DVT, Factor V Leiden (FVL) and prothrombin G20210A mutation (PGM) are the most common types of HT with an incidence of 20% to 25% and 6% to 18%, respectively. The objective of this study was to identify the incidence of FVL and PGM in posttraumatic VTE to determine whether routine screening for HT in trauma should be performed. METHODS: We conducted a prospective observational study at our Level I trauma center from 2013 to 2016 when 70 patients with posttraumatic DVT and PE were screened for FVL and PGM. Demographics, injury characteristics, and established risk factors for VTE were collected for each patient. Statistical analysis was performed to compare patients with and without HT. RESULTS: The incidence of FVL and PGM in posttraumatic VTE was 1.4% and 5.7%, respectively. All HT-positive patients had a DVT and one had an associated PE. Both the individual risk factors and the total number of risk factors for VTE were similar between the HT-positive group and the HT-negative group. CONCLUSION: There was a lower incidence of FVL and PGM in patients with posttraumatic DVT than in patients with a first-time DVT in the general population. HT does not appear to significantly contribute to posttraumatic VTE in our trauma population. Further research is warranted to determine whether routine screening for HT in trauma should be performed.

AB - BACKGROUND: Exosomes are extracellular vesicles that act as endogenous mediators of the immune response. We have previously shown that exosomes released into mesenteric lymph (ML) following trauma (T)/hemorrhagic shock (HS) induce proinflammatory cytokine production in macrophages and are involved in the pathogenesis of postshock acute lung injury. However, the cellular origin of ML exosomes and their role in the posttrauma immune response remains unclear. We hypothesized that exosomes released from damaged-intestinal epithelial cells contribute to posttrauma immune dysfunction by altering the function of dendritic cells (DCs), key regulators of the adaptive immunity. METHODS: Male rats underwent cannulation of the femoral artery, jugular vein and ML duct. T/HS was induced by laparotomy and 60 minutes of hemorrhagic shock followed by resuscitation. The ML was collected before (preshock) and after T/HS (post-T/HS) for isolation of exosomes. Surface epitopes of exosomes isolated from ML were assessed by flow cytometry to determine their cellular origin and phenotypic changes. The immunomodulatory effects of ML exosomes on DCs were assessed by Annexin V apoptosis assay, expression of costimulatory molecules, and antigen presenting capacity to lymphocytes. RESULTS: Exosomes isolated from ML highly expressed CD63 (exosome marker) and epithelial cell-specific marker, suggesting their derivation from intestinal epithelial cells. The expression of immunomodulatory molecules, such as major histocompatibility complex class II and Fas ligand on ML exosomes, was significantly increased after T/HS. Coincubation of DCs with exosomes isolated from ML after T/HS increased DC apoptosis twofold compared with preshock ML exosomes. Furthermore, post-T/HS ML exosomes significantly suppressed lipopolysaccharide-mediated expression of CD80 and CD86 on DCs as well as decreased their antigen-presenting capacity to induce lymphocytes proliferation. CONCLUSION: Gut epithelial cells release immunomodulatory exosomes into the ML after T/HS and resuscitation. Mesenteric lymph exosomes may be critical mediators of posttraumatic immunosuppression causing depletion and dysfunction of DCs. PMID- 29194316 TI - Tubastatin A prevents hemorrhage-induced endothelial barrier dysfunction. AB - BACKGROUND: Microvascular hyperpermeability resulting from endothelial barrier dysfunction (EBD) is associated with worse clinical outcomes in trauma-induced hemorrhagic shock. We have previously shown that treatment with Tubastatin A (TubA), a histone deacetylase 6 inhibitor, improves outcomes in animal models of shock. In this study, we investigate whether TubA treatment may prevent trauma related EBD. METHODS: Wistar-Kyoto rats subjected to 40% hemorrhage were treated with TubA or vehicle control. Acute lung injury (ALI) was assessed histologically from tissues harvested 6 hours posthemorrhage. In vitro, human umbilical vein endothelial cells (HUVECs) were cultured in EGM BulletKit medium. Medium was exchanged for glucose-free Dulbecco's Modified Eagle Medium (0.5% fetal bovine serum) with or without TubA, and cells were placed in an anoxic chamber (5% CO2, 95% N2, 20-48 hours). Expression of acetylated tubulin and hypoxia-inducible factor 1alpha was measured by Western blot. Soluble Intercellular Adhesion Molecule-1 concentration within the medium, a marker of endothelial integrity, was determined using enzyme-linked immunosorbent assay. Monolayers were assessed for permeability via transwell assays using fluorescein isothiocyanate-labeled albumin. RESULTS: Rats treated with TubA had significantly reduced ALI relative to vehicle control. In vitro, TubA significantly attenuated anoxia-induced hyperpermeability, hypoxia-inducible factor 1alpha expression, and glycocalyx shedding. CONCLUSIONS: Our findings demonstrate that TubA prevents hemorrhage induced ALI in rats. Additionally, we have shown that TubA prevents anoxia induced EBD in vitro. Taken together, these results suggest that TubA could attenuate microvascular hyperpermeability related to hemorrhagic shock. PMID- 29194318 TI - Non-compliance with ACS-COT recommended criteria for full trauma team activation is associated with undertriage deaths. AB - BACKGROUND: The appropriate triage of acutely injured patients within a trauma system is associated with improved rates of mortality and optimal resource utilization. The American College of Surgeons Committee on Trauma (ACS-COT) put forward six minimum criteria (ACS-6) for full trauma team activation (TTA). We hypothesized that ACS-COT verified trauma center compliance with these criteria is associated with low under-triage rates and improved overall mortality. METHODS: Data from a state-wide collaborative quality initiative was utilized. We used data collected from 2014 through 2016 at 29 ACS verified level 1 and 2 trauma centers. Inclusion criteria were: adult patients (>=16 years) and ISS >=5. Quantitative data existed to analyze four of the ACS-6 criteria (ED SBP<=90 mmHg, respiratory compromise/intubation, central GSW, and GCS<9). Patients were considered to be under-triaged if they had major trauma (ISS>15) and did not receive a full TTA. RESULTS: 51,792 patients were included in the study. Compliance with ACS-6 minimum criteria for full TTA varied from 51% to 82%. Presence of any ACS-6 criteria was associated with a high intervention rate and significant risk of mortality (OR 16.7, 95% CI 15.2-18.3, p<0.001). Of the 1004 deaths that were not a full activation, 433 (43%) were classified as under triaged, and 301 (30%) had at least one ACS-6 criteria present. Under-triaged patients with any ACS-6 criteria were more likely to die than those who were not under-triaged (30% vs 21%, p=0.001). GCS<9 and need for emergent intubation were the ACS-6 criteria most frequently associated with under-triage mortality. CONCLUSIONS: Compliance with ACS-COT minimum criteria for full TTA remains sub optimal and undertriage is associated with increased mortality. This data suggests that the most efficient quality improvement measure around triage should be ensuring compliance with the ACS-6 criteria. This study suggests that practice pattern modification to more strictly adhere to the minimum ACS-COT criteria for full TTA will save lives.

PMID- 29194319 TI - Variations in outcomes of emergency general surgery patients across hospitals: A call to establish emergency general surgery quality improvement program. AB - BACKGROUND: National Surgical Quality Improvement Program and Trauma Quality Improvement Program have shown variations in risk-adjusted outcomes across hospitals. Our study hypothesis was that there would be similar variation in risk adjusted outcomes of emergency general surgery (EGS) patients. METHODS: We undertook a retrospective analysis of the National Inpatient Sample database for 2010. Patients with EGS diseases were identified using American Association for the Surgery of Trauma definitions. A hierarchical logistic regression model was used to model in-hospital mortality, accounting for patient characteristics, including age, sex, race, ethnicity, insurance type, and comorbidities. Predicted to-expected mortality ratios with 90% confidence intervals were used to identify hospitals as low mortality (ratio significantly lower than 1), high mortality (ratio significantly higher than 1), or average mortality (ratio overlapping 1). RESULTS: Nationwide, 2,640,725 patients with EGS diseases were treated at 943 hospitals in 2010. About one-sixth of the hospitals (139, 15%) were low mortality, a quarter were high mortality (221, 23%), and the rest were average mortality. Mortality ratio at low mortality hospitals was almost four times lower than that of high mortality hospitals (0.57 vs. 2.03, p < 0.0001). If high and average mortality hospitals performed at the same level as low mortality hospitals, we estimate 16,812 (55%) more deaths than expected. CONCLUSION: There are significant variations in risk-adjusted outcomes of EGS patients across hospitals, with several thousand higher than expected number of deaths nationwide. Based on the success of National Surgical Quality Improvement Program and Trauma Quality Improvement Program, we recommend establishing EGS quality improvement program for risk-adjusted benchmarking of hospitals for EGS patients.

PMID- 29194320 TI - No intravenous access, no problem: Intraosseous administration of tranexamic acid is as effective as intravenous in a porcine hemorrhage model. AB - BACKGROUND: The acute coagulopathy of trauma is often accompanied by hyperfibrinolysis. Tranexamic acid (TXA) can reverse this phenomenon, and, when given early, decreases mortality from bleeding. Establishing intravenous (IV) access can be difficult in trauma and intraosseous (IO) access is often preferred for drug administration. Currently, there are no data on the efficacy of IO administered TXA. Our objectives were to compare serum concentrations of TXA when given IV and IO and to compare the efficacy of IO administered TXA to IV at reversing hyperfibrinolysis. METHODS: Using a porcine hemorrhage and ischemia reperfusion model, 18 swine underwent hemorrhagic shock followed by a tissue plasminogen activator infusion to induce hyperfibrinolysis. Animals then received an IV or tibial IO infusion of TXA over 10 minutes. Blood was then analyzed using rotational thromboelastometry to monitor reversal of hyperfibrinolysis. Serum was analyzed for drug concentrations. RESULTS: After hemorrhage and ischemia reperfusion, there were no significant differences in mean arterial pressure (48 vs. 49.5), lactate (11.1 vs. 10.8), and pH (7.20 vs. 7.22) between groups. Intraosseous TXA corrected the lysis index at 30 minutes in EX-TEM and IN-TEM, like IV infusion. Peak serum levels of TXA after IV and IO administration show concentrations of 160.9 MUg/mL and 132.57 MUg/mL respectively (p = 0.053). Peak levels occurred at the completion of infusion. Drug levels were tracked for four hours. At the end of monitoring, plasma concentrations of TXA were equivalent. CONCLUSION: Intraosseous administration of TXA is as effective as IV in reversing hyperfibrinolysis in a porcine model of hemorrhagic shock. Intraosseous administration was associated with a similar peak levels, pharmacokinetics, and clearance. Intraosseous administration of TXA can be considered in hemorrhagic shock when IV access cannot be established.

AB - BACKGROUND: Patients who sustain blunt liver trauma and are treated at an American College of Surgeons Committee on Trauma-verified Level I trauma center have an overall lower risk of mortality compared with patients admitted to a level II trauma center. However, elements contributing to these differences are unknown. We hypothesize that practice variation exists between trauma centers in management of blunt liver injury. Our objective is to identify practice variations and their effect on clinical outcomes. METHODS: Data from a statewide collaborative quality initiative for trauma were used. The data set contains information from 29 American College of Surgeons Committee on Trauma verified Levels I and II trauma centers from 2011 to 2016. Propensity score matching was used to create cohorts of patients treated at Levels I or II trauma centers. The 1:1 matched cohorts were used to compare in-hospital mortality, management strategy, complications, intensive care unit (ICU) and hospital length of stay, and failure to rescue. RESULTS: Four hundred fifty-four patients with grade 3 or higher blunt liver injury were included. Patients treated at level II trauma centers had higher in-hospital mortality than those treated at Level I trauma centers (15.4% vs 8.8%, p = 0.03). Level II trauma centers used angiography less compared with Level I centers (p = 0.007) and admitted significantly fewer patients to the ICU (p = 0.002). The ICU status was associated with reduced mortality (7.2% vs 23.9%, p < 0.001). Despite a lower rate of overall complications, Level II trauma centers were more likely to fail in rescuing their patients (p = 0.045). CONCLUSION: Admission with a high-grade liver injury to a Level II trauma center is associated with increased in-hospital mortality. Level II trauma centers were less likely to use angiography or admit high-grade liver injuries to the ICU. This variation in practice may lead to the inability to rescue critically ill patients. Future research should investigate contributors to underutilization of resources for patients with high-grade liver injuries. LEVEL OF EVIDENCE: Care management, level IV.

AB - BACKGROUND: The profound inflammatory response associated with brain death is frequently cited as the reason organs procured from brain dead donors are associated with worse graft function. The intestine releases inflammatory mediators in other types of shock, but its role is brain death has not been well studied. Direct peritoneal resuscitation (DPR) improves visceral organ blood flow and reduces inflammation after hemorrhagic shock. We hypothesized that use of DPR would maintain intestinal integrity and reduce circulating inflammatory mediators after brain death. METHODS: Brain death was induced in male Sprague-Dawley rats by inserting a 4F Fogarty catheter into the epidural space and slowly inflating it. After herniation, rats were resuscitated with normal saline to maintain a mean arterial pressure of 80 mm Hg and killed with tissue collected immediately (time 0), or 2 hours, 4 hours, or 6 hours after brain death. Randomly selected animals received DPR via an intraperitoneal injection of 30-mL commercial peritoneal dialysis solution. RESULTS: Levels of proinflammatory cytokines, including IL-1beta and IL-6, as well as high-mobility group box 1 protein and heat shock protein 70, were all increased after brain death and decreased with DPR. Fatty acid binding protein and lipopolysaccharide, both markers of intestinal injury, were increased in the serum after brain death and decreased with DPR. Immunohistochemistry staining for zona occludin-1 showed decreased intestinal tight junction integrity after brain death, which improved with DPR. CONCLUSIONS: Intestinal permeability increases after brain death, and this contributes to the increased inflammation seen throughout the body. Using DPR prevents intestinal ischemia and helps preserve intestinal integrity. This suggests that using this novel therapy as an adjunct to the resuscitation of brain dead donors has the potential to reduce inflammation and potentially improve the quality of transplanted organs.

AB - Health care leaders are responsible for oversight of multiple and competing change interventions. These interventions regularly fail to achieve the desired outcomes and/or sustainable results. This often occurs because of the mental models and approaches that are used to plan, design, implement, and evaluate the system. These do not account for inherent characteristics that determine the system's likely ability to innovate while maintaining operational effectiveness. Theories exist on how to assess a system's readiness to change, but the definitions, constructs, and assessments are diverse and often look at facets of systems in isolation. The Systems Transformation Framework prescriptively defines and characterizes system domains on the basis of complex adaptive systems theory so that domains can be assessed in tandem. As a result, strengths and challenges to implementation are recognized before implementation begins. The Systems Transformation Framework defines 8 major domains: vision, leadership, organizational culture, organizational behavior, organizational structure, performance measurements, internal learning, and external learning. Each domain has principles that are critical for creating the conditions that lead to successful organizational adaptation and change. The Systems Transformation Framework can serve as a guide for health care leaders at all levels of the organization to (1) create environments that are change ready and (2) plan, design, implement, and evaluate change within complex adaptive systems. PMID- 29194329 TI - Buildings, Barriers, and Breakthroughs: Bridging Gaps in the Health Care Enterprise. AB - Health care architecture and design are critical resources that are often underestimated and overlooked. As we seek to extract every available resource at our disposal to serve patients and sustain the bottom line, it is vital that we consider the influence the building imposes on the patient and caregiver experiences. Buildings impact both caregiver behaviors and the economic enterprise and are, therefore, the business of health care executives. This understanding is not only an executive obligation, it is an executive opportunity. Furthermore, the built environment can be a source for innovation in an industry whose future depends on nurse leaders to champion ingenuity with simplicity and relevance. Nurse leaders are ideally positioned to bridge health care building design and best practice. PMID- 29194330 TI - Accelerating Innovation Through Coopetition: The Innovation Learning Network Experience. AB - Coopetition, the simultaneous pursuit of cooperation and competition, is a growing force in the innovation landscape. For some organizations, the primary mode of innovation continues to be deeply secretive and highly competitive, but for others, a new style of shared challenges, shared purpose, and shared development has become a superior, more efficient way of working to accelerate innovation capabilities and capacity. Over the last 2 decades, the literature base devoted to coopetition has gradually expanded. However, the field is still in its infancy. The majority of coopetition research is qualitative, primarily consisting of case studies. Few studies have addressed the nonprofit sector or service industries such as health care. The authors believe that this article may offer a unique perspective on coopetition in the context of a US-based national health care learning alliance designed to accelerate innovation, the Innovation Learning Network or ILN. The mission of the ILN is to "Share the joy and pain of innovation," accelerating innovation by sharing solutions, teaching techniques, and cultivating friendships. These 3 pillars (sharing, teaching, and cultivating) form the foundation for coopetition within the ILN. Through the lens of coopetition, we examine the experience of the ILN over the last 10 years and provide case examples that illustrate the benefits and challenges of coopetition in accelerating innovation in health care. PMID- 29194331 TI - Kaiser's School of Nursing: A 70-Year Legacy of Disruptive Innovation. AB - A legacy project was launched in 2016 to research, capture, and record the history and voice of Kaiser Foundation School of Nursing alumni. The inspirational stories of these early nursing pioneers emerged within a disruptive and innovative health care system known as Kaiser Permanente. Led by a doctorally prepared nurse director, the new school boldly rejected the dominant social norms of the 1940s by welcoming minorities and offering an unprecedented curriculum that prioritized prevention, health promotion, and wellness over conventional institutionalized sick care models. Kaiser Foundation School of Nursing alumni became Kaiser Permanente's earliest nurse leaders, educators, and care advocates. They helped revolutionize the key concepts of integrated patient care. As early innovators, many graduates pursued advanced degrees and were instrumental in defining expanded nursing roles, including the introduction of nurse practitioners in California. How Kaiser Foundation School of Nursing transcended the traditions and cultural norms of the day offers a reflective narrative on the enduring leadership attributes of disruptive innovation and the nurse executive's role in reimagining care for future generations. PMID- 29194332 TI - Operationalizing a Nursing Innovation Center Within a Health Care System. AB - In nursing, the terms "innovation" and "innovative" are used freely, especially when individuals or groups either develop something new or improve upon current practice. Innovation is often considered adjunct work, not part of foundational work that aims to meet the vision, mission, and values of the organization. Nurse leaders must include innovation as an important theme of this foundational work. Innovation must become a core expectation of all nurses and nursing team members. Team members can provide ideas that lead to innovations. They can also carry out roles that enhance or cultivate ideas, promote prototyping, ensure innovative ideas are efficacious and effective, and facilitate dissemination and diffusion into practice. To ensure that innovation is incorporated as part of nursing practice and then sustained over time, horizontal (elemental) and vertical (global) infrastructure and processes are needed. In this article, operationalization of a Nursing Innovation Center is described and rationale for specific horizontal and vertical services and features is discussed. PMID- 29194333 TI - Nursing Integration and Innovation Across a Multisystem Enterprise: Priorities for Nurse Leaders. AB - There is no escaping the fact that the ability to skillfully influence change is a requirement for nurse leaders. This need is intensified as the national health care system reforms and as the morphology of health care systems continues to change, especially in academic health care systems. The purpose of this article was 2-fold. The first objective was to relay the experience of the integration of nursing practice, education, and research within an academic health care system. The second was to, through this story of integration, expose the uniqueness and importance of nurse leader roles influencing innovation across a multisystem enterprise to fulfill the organization's mission. PMID- 29194334 TI - Creativity and Innovation in Health Care: Tapping Into Organizational Enablers Through Human-Centered Design. AB - There is an increasing drive in health care for creativity and innovation to tackle key health challenges, improve quality and access, and reduce harm and costs. Human-centered design (HCD) is a potential approach to achieving organizational innovation. However, research suggests the nursing workforce feels unsupported to take the risks needed for innovation, and leaders may not understand the conditions required to fully support them. The aim of this study was to identify enabling conditions that support frontline nurses in their attempts to behave as champions of innovation and change. An HCD workshop was undertaken with 125 nurses employed in clinical practice at Kaiser Permanente. The workshop included empathy mapping and semistructured questions that probed participant experiences with innovation and change. The data were collated and thematic analysis undertaken through a Grounded Theory approach. The data were analyzed to identify key enabling conditions. Seven enablers emerged: personal need for a solution; challenges that have meaningful purpose; clarity of goal and control of resources; active experimentation; experiences indicating progress; positive encouragement and confidence; and provision of psychological safety. These enablers were then translated into pragmatic guidelines for leaders on how the tools of HCD may be leveraged for innovation and change in health care. PMID- 29194335 TI - The CNO and Leading Innovation: Competencies for the Future. AB - Although innovation is critical to success in today's tumultuous environment, health care is slow to embrace it, and there is significant variability in strategic adoption of innovation across organizations. Nurse leaders do not need to be innovators themselves but must engage in, and have the ability to create, an organizational culture of innovation. Twenty-six leadership behaviors specific to innovation leadership were identified through a Delphi study to develop competencies as well as the knowledge, skills, and attitudes that support nurse leaders in acquiring or expanding the capability of nurse leaders to create a culture of innovation. It was demonstrated that nursing innovation experts were able to differentiate between general leadership behaviors and innovation leader behaviors. In addition, the need to acquire basic leadership competencies before mastering innovation leader competencies was identified. Five strategies to initiate or expand a culture of innovation in organizations were identified, including (1) assessment of organizational capacity for innovation; (2) acknowledgement of the responsibility of all leaders to create an innovation-rich environment; (3) provision of education, skill building, and coaching; (4) encouragement of an ongoing practice of innovation, even in the face of failure; and (5) development of a sustainable culture of innovation. PMID- 29194336 TI - International Nursing: Constructing an Advanced Practice Registered Nurse Practice Model in the UAE: Using Innovation to Address Cultural Implications and Challenges in an International Enterprise. AB - Despite utilization of the advanced practice registered nurse (APRN) in the United States health care system, there is little information about the introduction, utilization, and challenges of the APRN role globally, especially in the Middle East. This article will look at how one hospital in the United Arab Emirates introduced the APRN role to a health care environment of a country where it has not been recognized historically. Cultural challenges and barriers for the implementation of the role include regulatory, societal, and institutional. Innovation and collaboration are necessary to address these challenges and barriers and to pave the way for a successful advanced practice model pilot, as well as for the future use of the role. Innovation is also one of the key performance indicators for the country's health care. However, the idea of advanced practice is a new concept that has been outside the mainstream health care practice for the United Arab Emirates. To help with the implementation, a road map was developed to outline the steps necessary to provide a safe practice environment. The plan included aligning with the ministry of health nursing and midwifery council, as well as the Health Authority of Abu Dhabi, to help them learn more about the US model of advanced practice, along with benefits, and outcomes of the role. Developing the role of the APRN will benefit the future state of the health care infrastructure for not only the United Arab Emirates but throughout the Middle East.

PMID- 29194338 TI - Nurses' Use of Positive Deviance When Encountering Electronic Health Records Related Unintended Consequences. AB - As organizations adopt electronic health records (EHRs), nurses frequently encounter system barriers and difficulty performing role expectations. This article describes nurses' experiences with unintended consequences emerging from the use of an EHR. In some situations, nurses were positively deviant when encountering unintended consequences relating to EHRs to accomplish patient care or protect patient safety. Nurses engaged in work-arounds to provide patient care when the EHR did not meet their needs, sometimes in positively deviant ways. Qualitative data were collected from 5 open-ended questions at the end of a quantitative survey. Analysis included coding of responses and organization of processes in line with the triangle model, a human factors framework, to identify overarching themes. Five themes emerged: (1) User support after implementation of EHR; (2) User satisfaction with EHR; (3) Communication for patient care, quality, and safety; (4) Effort to complete tasks; and (5) Areas for improvement. Nurses' ability to adopt positive deviance as they experience unintended consequences offers opportunities for organizations to engage nursing perspectives in improving the EHR and engineer it to be more resilient to nursing work. PMID- 29194340 TI - Heat Shock Factor 1 Inhibits the Expression of Suppressor of Cytokine Signaling 3 in Cerulein-Induced Acute Pancreatitis. AB - BACKGROUND: Heat shock factor 1 (HSF1), an important transcriptional molecule in the heat shock process, can regulate the expression of a lot of inflammatory mediators in addition to heat shock proteins. This study evaluated the inhibitive function of HSF1 on the expression of suppressor of cytokine signaling 3 in cerulein-induced acute pancreatitis. METHODS: After HSF1 mice, HSF1 mice, and AR42J cells were treated with cerulein, histopathological score, expression of SOCS3 mRNA, and protein levels were analyzed by using RT-PCR, quantitative real time RT-PCR, and western blotting, respectively. DNA binding and transcription activity of HSF1 to the SOCS3 promoter were detected by chromatin immunoprecipitation and luciferase reporter assays. RESULTS: The histopathological scores of the pancreas decreased significantly in the cerulein induced HSF1 mice compared with the cerulein-induced HSF1 mice. SOCS3 mRNA and protein level decreased in the pancreas of the unstimulated HSF1 and HSF1 mice, whereas increased in the pancreas of the cerulein-induced HSF1 and HSF1 mice, with higher in the pancreas of cerulein-induced HSF1mice. In the pcDNA3.1 transfected AR42J cells, SOCS3 protein decreased and was upregulated after the cerulein stimulation, whereas HSF1 overexpression inhibited the upregulation. In the scramble-transfected AR42J cells, SOCS3 protein decreased and was upregulated after the cerulein stimulation, whereas HSF1-RNAi further promoted the upregulation. EMSA and chromatin immunoprecipition showed that HSF1 could directly bind to SOCS3 promoter region. Reporter assays showed that HSF1 could inhibit the transcriptional activity on SOCS3 promoter. CONCLUSIONS: HSF1 can protect AR42J cells from cerulein-induced pancreatitis through inhibiting the expression of SOCS3. PMID- 29194339 TI - Risk Factors for the Development of Acute Respiratory Distress Syndrome Following Hemorrhage. AB - BACKGROUND: The Pragmatic Randomized Optimal Platelet and Plasma Ratios (PROPPR) study evaluated the effects of plasma and platelets on hemostasis and mortality after hemorrhage. The pulmonary consequences of resuscitation strategies that mimic whole blood, remain unknown. METHODS: A secondary analysis of the PROPPR study was performed. Injured patients predicted to receive a massive transfusion were randomized to 1:1:1 versus 1:1:2 plasma-platelet-red blood cell ratios at 12 Level I North American trauma centers. Patients with survival >24 h, an intensive care unit (ICU) stay, and a recorded PaO2/FiO2 (P/F) ratio were included. Acute respiratory distress syndrome (ARDS) was defined as a P/F ratio < 200, with bilateral pulmonary infiltrates, and adjudicated by investigators. RESULTS: Four hundred fifty-four patients were reviewed (230 received 1:1:1, 224 1:1:2). Age, sex, injury mechanism, and regional abbreviated injury scale (AIS) scores did not differ between cohorts. Tidal volume, positive end-expiratory pressure, and lowest P/F ratio did not differ. No significant differences in ARDS rates (14.8% vs. 18.4%), ventilator-free (24 vs. 24) or ICU-free days (17.5 vs. 18), hospital length of stay (22 days vs. 18 days), or 30-day mortality were found (28% vs. 28%). ARDS was associated with blunt injury (OR 3.61 [1.53-8.81] P < 0.01) and increasing chest AIS (OR 1.40 [1.15-1.71] P < 0.01). Each 500 mL of crystalloid infused during hours 0 to 6 was associated with a 9% increase in the rate of ARDS (OR 1.09 [1.04-1.14] P < 0.01). Blood given at 0 to 6 or 7 to 24 h were not risk factors for lung injury. CONCLUSION: Acute crystalloid exposure, but not blood products, is a potentially modifiable risk factor for the prevention of ARDS following hemorrhage. PMID- 29194341 TI - Applying Positive End-Expiratory Pressure During Mechanical Ventilation Causes Pulmonary Redox Imbalance and Inflammation in Rats. AB - BACKGROUND: Mechanical ventilation (MV) may induce or aggravate lung injury through the production of cytokines, inflammatory infiltration of neutrophils, and changes in the permeability of the alveolar-capillary barrier. The use of positive end-expiratory pressure (PEEP) helps improve gas exchanges avoiding alveolar collapse at the end of expiration. The present study aimed to analyze inflammatory response and redox imbalance in lungs of rats submitted to MV with and without PEEP. METHODS: Eighteen Wistar rats were divided into three groups: control (CG), PEEP group (PG), and zero PEEP (ZEEP) group (ZG). PG and ZG were submitted to MV for 60 min with or without PEEP, respectively. Subsequently, the animals were euthanized, and blood, bronchoalveolar lavage fluid, and lungs were collected for analyses. RESULTS: The number of neutrophils was higher in PG compared with CG. Leucocyte and neutrophil influx in bronchoalveolar lavage fluid was higher in PG compared with CG. PG showed an increase in alveolar area compared with the other groups. There were increases in the levels of chemokines, CCL3 and CCL5, in PG compared with CG. There were increases in oxidation of lipids and proteins in PG compared with other groups. There were increases in the activity of superoxide dismutase and catalase in PG compared with CG and ZG. However, there was a decrease in the ratio of glutathione to glutathione disulfide in PG compared with other groups. CONCLUSIONS: MV with PEEP caused redox imbalance and inflammation in lungs of healthy rats. PMID- 29194342 TI - Tim-3 Regulates Tregs' Ability to Resolve the Inflammation and Proliferation of Acute Lung Injury by Modulating Macrophages Polarization. AB - We recently reported that CD4CD25 regulatory T cells (Tregs) contributed to the recovery of patients with acute lung injury (ALI) by upregulating T cell immunoglobulin and mucin-domain containing-3 (Tim-3). However, the molecular mechanism by which Tim-3 regulates Tregs' function in the resolution and fibroproliferation after ALI remains unknown. In this study, we adoptively transferred Tim-3Tregs or Tim-3Tregs into lipopolysaccharide -induced ALI mice model. Data demonstrated that Tim-3Tregs not only decreased indices of lung inflammation and injury but also mitigated lung fibrosis after ALI. Furthermore, we observed that the transfer of Tim-3Tregs led to M2-like macrophage differentiation as demonstrated by significantly upregulated levels of M2 associated phenotypic markers as well as downregulated expressions of M1-related markers in both the profibrotic lung tissue and sorted pulmonary monocytes after ALI. In addition, cytokines such as interleukin (IL)-10 and IL-4 were also upregulated in lung tissues after Tim-3Tregs transferring. In vitro experiments further demonstrated that cell-contact cocultures with Tregs lacking Tim-3 presented decreased polarization of M2-like macrophages partially mediated by a decreased expression and function of STAT-3. Therefore, these data demonstrate a previously unrecognized function of Tim-3 on Tregs in their ability to repress the fibroproliferation of ALI by inducing alternative macrophages polarization. Moreover, the data highlight that Tim-3Tregs-mediated induction of M2-like macrophages may be a novel treatment modality with transitional potential. PMID- 29194343 TI - Blood Mixing Upregulates Platelet Membrane-Bound CD40 Ligand Expression In Vitro Independent of Abo Compatibility. AB - Platelets play a central role in the inflammation response via CD40 ligand (CD40L) expression, which may lead to transfusion reactions. The precise role of platelet CD40L-mediated inflammation in transfusion reactions is unclear. Therefore, we assessed the effects of in vitro blood mixing on platelet CD40L expression. In addition, we examined the effect of ABO compatibility on CD40L expression. Donor-packed red blood cells were acquired from a blood bank, and recipient blood was obtained from patients undergoing cardiac surgery and prepared as washed platelets. Donor blood was mixed with suspended, washed recipient platelets to obtain a final mixing ratio of 1%, 5%, or 10% (vol/vol). The blood mixtures were divided into three groups: group M, cross-matched blood type mixing (n = 20); group S, ABO type-specific uncross-matched blood (n = 20); and group I, ABO incompatibility (not ABO type-specific blood and not process cross-matched) mixing (n = 20). The blood mixtures were used to detect platelet membrane-bound CD40L expression by flow cytometry. Blood mixing resulted in an increase in CD40L expression in group M (P < 0.001), group S (P < 0.001), and group I (P < 0.001). CD40L expression after blood mixing potentially led to a transfusion reaction in each of the groups. There were no differences in CD40L expression among the three groups (P = 0.988) correlated with ABO compatibility or incompatibility. This indicates that the reactions between red blood cell surface antigens and plasma antibodies do not play a role in the induction of CD40L expression. PMID- 29194344 TI - Direct Peritoneal Resuscitation Alters Leukocyte Infiltration in the Lung After Acute Brain Death. AB - BACKGROUND: Brain death is associated with significant lung injury and inflammation. This has been associated with worse long-term outcomes for transplanted lungs. Direct peritoneal resuscitation (DPR) reduces systemic inflammation in brain death and improves lung procurement rate. The effect of DPR on macrophage and neutrophil infiltration in the lungs is not known. METHODS: Male Sprague-Dawley rats had a 4F Fogarty catheter inserted into the skull and the balloon inflated until brain death was achieved. Rats were resuscitated with normal saline to maintain a mean arterial pressure of 80 mmHg (targeted intravenous fluid, TIVF) and DPR animals received an intraperitoneal injection of commercial peritoneal dialysis solution. Rats were sacrificed at 0, 2, 4, and 6 h after brain death. Protein levels were assessed using quantitative ELISA. Leukocytes were quantified using flow cytometry and immunohistochemistry. RESULTS: At all time points, DPR downregulated multiple inflammatory cytokines including IFN-gamma, TNF-alpha, IL-1alpha, and IL-6. Adhesion molecules ICAM, E selectin, and P-selectin were increased above sham at 4 and 6 h after brain death and reduced with DPR, whereas VCAM was reduced at 2 and 6 h. Infiltration of macrophages and neutrophils were trended downward at 6 h with DPR, though this difference was not statistically significant. CONCLUSIONS: Animals that received TIVF alone had significant increases in inflammatory cytokines within the lung tissue, leading to adhesion molecule expression and ultimately leukocyte infiltration. Each stage of inflammation was affected by DPR. Using DPR in brain dead organ donors shows promise as a way to reduce lung injury and inflammation.

AB - Drinking mothers expose their fetuses to ethanol, which produces birth defects: craniofacial defects, cognitive impairment, sensorimotor disabilities and organ deformities, collectively termed as fetal alcohol spectrum disorder (FASD). Various congenital heart defects (CHDs) are present in FASD patients, but the mechanisms of alcohol-induced cardiogenesis defects are not completely understood. This study utilized zebrafish embryos and older larvae to understand FASD-associated CHDs. Ethanol-induced cardiac chamber defects initiated during embryonic cardiogenesis persisted in later zebrafish life. In addition, myocardial damage was recognizable in the ventricle of the larvae that were exposed to ethanol during embryogenesis. Our studies of the pathogenesis revealed that ethanol exposure delayed differentiation of first and second heart fields and reduced the number of early- and late-added cardiomyocytes in the heart. Ethanol exposure also reduced the number of endocardial cells. Together, this study showed that ethanol-induced heart defects were present in late-stage zebrafish larvae. Reduced numbers of cardiomyocytes partly accounts for the ethanol-induced zebrafish heart defects. PMID- 29194346 TI - Dental Procedures in Primary Health Care of the Brazilian National Health System. AB - The aim of this study was to examine the procedures of primary dental health care performed by oral health teams (OHTs) adhering to the second cycle of the 'National Programme for Improving Access and Quality of Primary Care' (PMAQ-AB) in Brazil. A cross-sectional descriptive analysis was performed, across 23 dental procedures comprising preventive, restorative/prosthetic, surgical, endodontic and oral cancer monitoring. Descriptive analysis shows that most of the oral health teams carry out basic dental procedures. However, most of the time, they do not keep adequate records of suspected cases of oral cancer, diagnosis tests or follow-ups, and do not perform dental prosthetic procedures. Data also showed disparities in the average number of procedures performed in each Brazilian geographical region in 2013-2014, ranging from 13.9 in the northern to 16.5 in the southern and south-eastern regions, reinforcing the great social disparities between them. Brazilian regions with the highest volume of dental needs deliver the lowest number of dental procedures. The need to expand the supply of prostheses and the early diagnosis of oral cancer in primary health care (PHC) is evident.

AB - Natural products are a prolific source for the identification of new biologically active compounds. In the present work, we studied the in vitro and in vivo antimalarial efficacy and ADME-Tox profile of a molecular hybrid (AM1) between 4 aminoquinoline and a quinolizidine moiety derived from lupinine (Lupinus luteus). The aim was to find a compound endowed with the target product profile-1 (TCP-1: molecules that clear asexual blood-stage parasitaemia), proposed by the Medicine for Malaria Venture to accomplish the goal of malaria elimination/eradication. AM1 displayed a very attractive profile in terms of both in vitro and in vivo activity. By using standard in vitro antimalarial assays, AM1 showed low nanomolar inhibitory activity against chloroquine-sensitive and resistant P. falciparum strains (range IC50 16-53 nM), matched with a high potency against P. vivax field isolates (Mean IC50 29 nM). Low toxicity and additivity with artemisinin derivatives were also demonstrated in vitro. High in vivo oral efficacy was observed in both P.berghei and P. yoelii mouse models with IC50 values comparable or better than those of chloroquine. The metabolic stability in different species and the pharmacokinetic profile in the mouse model makes AM1 a compound worth further investigation as a potential novel schizonticidal agent. PMID- 29194349 TI - Polymorphism Analysis of Ch1 and Ch2 Genes in the Siberian Cat. AB - Cats are usually spreaders of allergens that are critical for sensitive people; the Siberian cat is a breed supposed to be low level allergenic, according to some breeders' statements. The sequence of the two genes, namely Ch1 and Ch2, that code for the allergen Fel d 1, the major allergen responsible for outbreaks of allergy symptoms, is not yet known in the Siberian cat, and finding this was the aim of our investigation. Notably, our work is the first survey of the genetic structure of these genes in Siberian cats. The comparison of the sequences of Siberian cats, non-Siberian cats, and sequences present in the National Center for Biotechnology Information database revealed a considerable number of mutations; some of those detected in the Siberian cat, due to their position in exon regions, could affect the Fel d 1 allergenic properties. Therefore, further investigations are recommended to assess if the identified mutations can be responsible for a reduced-allergen synthesis and can be used as markers for selection of low level allergenic cats. PMID- 29194348 TI - alpha-Glucosidase and Protein Tyrosine Phosphatase 1B Inhibitory Activity of Plastoquinones from Marine Brown Alga Sargassum serratifolium. AB - Sargassum serratifolium C. Agardh (Phaeophyceae, Fucales) is a marine brown alga that belongs to the family Sargassaceae. It is widely distributed throughout coastal areas of Korea and Japan. S. serratifolium has been found to contain high concentrations of plastoquinones, which have strong anti-cancer, anti inflammatory, antioxidant, and neuroprotective activity. This study aims to investigate the anti-diabetic activity of S. serratifolium and its major constituents through inhibition of protein tyrosine phosphatase 1B (PTP1B), alpha glucosidase, and ONOO--mediated albumin nitration. S. serratifolium ethanolic extract and fractions exhibited broad PTP1B and alpha-glucosidase inhibitory activity (IC50, 1.83~7.04 and 3.16~24.16 ug/mL for PTP1B and alpha-glucosidase, respectively). In an attempt to identify bioactive compounds, three plastoquinones (sargahydroquinoic acid, sargachromenol and sargaquinoic acid) were isolated from the active n-hexane fraction of S. serratifolium. All three plastoquinones exhibited dose-dependent inhibitory activity against PTP1B in the IC50 range of 5.14-14.15 uM, while sargachromenol and sargaquinoic acid showed dose-dependent inhibitory activity against alpha-glucosidase (IC50 42.41 +/- 3.09 and 96.17 +/- 3.48 uM, respectively). In the kinetic study of PTP1B enzyme inhibition, sargahydroquinoic acid and sargaquinoic acid led to mixed-type inhibition, whereas sargachromenol displayed noncompetitive-type inhibition. Moreover, plastoquinones dose-dependently inhibited ONOO--mediated albumin nitration. Docking simulations of these plastoquinones demonstrated negative binding energies and close proximity to residues in the binding pocket of PTP1B and alpha-glucosidase, indicating that these plastoquinones have high affinity and tight binding capacity towards the active site of the enzymes. These results demonstrate that S. serratifolium and its major plastoquinones may have the potential as functional food ingredients for the prevention and treatment of type 2 diabetes. PMID- 29194350 TI - The Marine Fungi Rhodotorula sp. (Strain CNYC4007) as a Potential Feed Source for Fish Larvae Nutrition. AB - Fish oil is used in the production of feed for cultured fish owing to its high polyunsaturated fatty acid content (PUFA). The over-exploitation of fisheries and events like "El Nino" are reducing the fish oil supply. Some marine microorganisms are considered potentially as alternative fatty acid sources. This study assesses a strain of Rhodotorula sp. (strain CNYC4007; 27% docosahexaenoic acid (DHA) of total fatty acids), as feed for fish larvae. The total length and ribonucleic acid (RNA)/deoxyribonucleic acid (DNA) ratio of Danio rerio larvae was determined at first feeding at six and 12 days old (post-yolk absorption larvae). Larvae fed with microencapsulated Rhodotorula sp. CNYC4007 had a significantly higher RNA/DNA ratio than control group (C1). At six days post-yolk absorption group, the RNA/DNA ratio of larvae fed with Rhodotorula sp. bioencapsulated in Brachionus sp. was significantly higher than control group fed with a commercial diet high in DHA (C2-DHA). Finally, at 12 days post-yolk absorption, the RNA/DNA ratio was significantly higher in larvae fed with Rhodotorula sp. CNYC4007 and C2-DHA (both bioencapsulated in Artemia sp. nauplii) than in control group (C1). These results suggest that Rhodotorula sp.

AB - We previously reported that raloxifene, an estrogen receptor modulator, is also a ligand for the aryl hydrocarbon receptor (AhR). Raloxifene induces apoptosis in estrogen receptor-negative human cancer cells through the AhR. We performed structure-activity studies with seven raloxifene analogs to better understand the structural requirements of raloxifene for induction of AhR-mediated transcriptional activity and apoptosis. We identified Y134 as a raloxifene analog that activates AhR-mediated transcriptional activity and induces apoptosis in MDA MB-231 human triple negative breast cancer cells. Suppression of AhR expression strongly reduced apoptosis induced by Y134, indicating the requirement of AhR for Y134-induced apoptosis. Y134 also induced apoptosis in hepatoma cells without having an effect on cell cycle regulation. Toxicity testing on zebrafish embryos revealed that Y134 has a significantly better safety profile than raloxifene. Our studies also identified an analog of raloxifene that acts as a partial antagonist of the AhR, and is capable of inhibiting AhR agonist-induced transcriptional activity. We conclude that Y134 is a promising raloxifene analog for further optimization as an anti-cancer agent targeting the AhR.

AB - Animal leptospirosis, exempt in rodents, manifests as peculiar biology where the animal can function, simultaneously or not, as a susceptible host or reservoir. In the first case, clinical symptoms are likely. In the second case, infection is subclinical and manifestations are mild or absent. Mild clinical symptoms encompass reproductive failure in production animals for host-adapted Leptospira sp. serovars. This work presents a study on Leptospira sp. infection in a mixed species (bovine and swine) farm with documented reproductive disorders in the cattle unit. A long calving interval (above 450 days) was the hallmark observed in cows. Some cows (2/26 tested) presented a high titre of antibodies against Leptospira sp. serogroup Sejroe, but the overall within-herd prevalence was low (11.5% and 7.7% for cut-off titres of 1:30 and 1:100, respectively). The in-herd prevalence of leptospirosis in the sow unit (determined for 113/140 animals) was high when using a lowered cut-off threshold (32.7% vs. 1.8% for cut-off titre of 1:30 and 1:100, respectively). In this unit, the most prevalent serogroup was Autumnalis. The final diagnostic confirmation of Leptospira sp. maintenance within the farm was obtained through detection by PCR of Leptospira sp. DNA in an aborted swine litter. Despite the fact that a common causative infective agent was diagnosed in both species, the direct link between the two animal units was not found. Factors such as drinking from the same water source and the use of manure prepared with the swine slurry might raise suspicion of a possible cross contamination between the two units. In conclusion, this work suggests that leptospirosis be included in the differential diagnosis of reproductive disorders and spontaneous abortions in production animals and provides data that justify the use of a lowered threshold cut-off for herd diagnosis.

The benefits of shrimp farming include a relatively short grow-out time, high sale price, and good cost recovery. However, outbreaks of serious diseases inflict serious losses, and acute hepatopancreatic necrosis disease (AHPND) is an emerging challenge to this industry. In South American white shrimp (Penaeus vannamei) and grass shrimp (Penaeus monodon), this disease has a 70-100% mortality. The pathogenic agent of AHPND is a specific strain of Vibrio parahaemolyticus which contains PirAvp and PirBvp toxins encoded in the pVA1 plasmid. PirAvp and PirBvp have been shown to cause the typical histological symptoms of AHPND in infected shrimps, and in this review, we will focus on our structural understanding of these toxins. By analyzing their structures, a possible cytotoxic mechanism, as well as strategies for anti-AHPND drug design, is proposed.

AB - On 10 August 2016 China launched the GF-3, its first C-band polarimetric synthetic aperture radar (SAR) satellite, which was put into operation at the end of January, 2017. GF-3 polarimetric SAR has many advantages such as high resolution and multi-polarization imaging capabilities. Polarimetric SAR can fully characterize the backscatter property of targets, and thus it is of great interest to explore the physical scattering mechanisms of terrain types, which is very important in interpreting polarimetric SAR imagery and for its further usages in Earth observations. In this paper, focusing on target scattering characterization and feature extraction, we generalize the Delta alpha B / alpha B method, which was proposed under the reflection symmetric assumption, for the general backscatter process to account for both the reflection symmetry and asymmetry cases. Then, we evaluate the performances of physical scattering mechanism analysis methods for GF-3 polarimetric SAR imagery. Radarsat-2 data acquired over the same area is used for cross validation. Results show that GF-3 polarimetric SAR data has great potential for target characterization, especially for ocean area observation. PMID- 29194356 TI - A Pseudorange Measurement Scheme Based on Snapshot for Base Station Positioning Receivers. AB - Digital multimedia broadcasting signal is promised to be a wireless positioning signal. This paper mainly studies a multimedia broadcasting technology, named China mobile multimedia broadcasting (CMMB), in the context of positioning. Theoretical and practical analysis on the CMMB signal suggests that the existing CMMB signal does not have the meter positioning capability. So, the CMMB system has been modified to achieve meter positioning capability by multiplexing the CMMB signal and pseudo codes in the same frequency band. The time difference of arrival (TDOA) estimation method is used in base station positioning receivers. Due to the influence of a complex fading channel and the limited bandwidth of receivers, the regular tracking method based on pseudo code ranging is difficult to provide continuous and accurate TDOA estimations. A pseudorange measurement scheme based on snapshot is proposed to solve the problem. This algorithm extracts the TDOA estimation from the stored signal fragments, and utilizes the Taylor expansion of the autocorrelation function to improve the TDOA estimation accuracy. Monte Carlo simulations and real data tests show that the proposed algorithm can significantly reduce the TDOA estimation error for base station positioning receivers, and then the modified CMMB system achieves meter positioning accuracy. PMID- 29194355 TI - Characterization of the EBV-Induced Persistent DNA Damage Response. AB - Epstein-Barr virus (EBV) is an oncogenic herpesvirus that is ubiquitous in the human population. Early after EBV infection in vitro, primary human B cells undergo a transient period of hyper-proliferation, which results in replicative stress and DNA damage, activation of the DNA damage response (DDR) pathway and, ultimately, senescence. In this study, we investigated DDR-mediated senescence in early arrested EBV-infected B cells and characterized the establishment of persistent DNA damage foci. We found that arrested EBV-infected B cells exhibited an increase in promyelocytic leukemia nuclear bodies (PML NBs), which predominantly localized to markers of DNA damage, as well as telomeric DNA. Furthermore, arrested EBV-infected B cells exhibited an increase in the presence of telomere dysfunction-induced foci. Importantly, we found that increasing human telomerase reverse transcriptase (hTERT) expression with danazol, a drug used to treat telomere diseases, permitted early EBV-infected B cells to overcome cellular senescence and enhanced transformation. Finally, we report that EBV infected B cells undergoing hyper-proliferation are more sensitive than lymphoblastoid cell lines (LCLs) to inhibition of Bloom syndrome-associated helicase, which facilitates telomere replication. Together, our results describe the composition of persistent DNA damage foci in the early stages of EBV infection and define key regulators of this barrier to long-term outgrowth. PMID- 29194357 TI - A Direct Bicarbonate Detection Method Based on a Near-Concentric Cavity-Enhanced Raman Spectroscopy System. AB - Raman spectroscopy has great potential as a tool in a variety of hydrothermal science applications. However, its low sensitivity has limited its use in common sea areas. In this paper, we develop a near-concentric cavity-enhanced Raman spectroscopy system to directly detect bicarbonate in seawater for the first time. With the aid of this near-concentric cavity-enhanced Raman spectroscopy system, a significant enhancement in HCO3- detection has been achieved. The obtained limit of detection (LOD) is determined to be 0.37 mmol/L-much lower than the typical concentration of HCO3- in seawater. By introducing a specially developed data processing scheme, the weak HCO3- signal is extracted from the strong sulfate signal background, hence a quantitative analysis with R2 of 0.951 is made possible. Based on the spectra taken from deep sea seawater sampling, the concentration of HCO3- has been determined to be 1.91 mmol/L, with a relative error of 2.1% from the reported value (1.95 mmol/L) of seawater in the ocean. It is expected that the near-concentric cavity-enhanced Raman spectroscopy system could be developed and used for in-situ ocean observation in the near future. PMID- 29194358 TI - Automated Ecological Assessment of Physical Activity: Advancing Direct Observation. AB - Technological advances provide opportunities for automating direct observations of physical activity, which allow for continuous monitoring and feedback. This pilot study evaluated the initial validity of computer vision algorithms for ecological assessment of physical activity. The sample comprised 6630 seconds per camera (three cameras in total) of video capturing up to nine participants engaged in sitting, standing, walking, and jogging in an open outdoor space while wearing accelerometers. Computer vision algorithms were developed to assess the number and proportion of people in sedentary, light, moderate, and vigorous activity, and group-based metabolic equivalents of tasks (MET)-minutes. Means and standard deviations (SD) of bias/difference values, and intraclass correlation coefficients (ICC) assessed the criterion validity compared to accelerometry separately for each camera. The number and proportion of participants sedentary and in moderate-to-vigorous physical activity (MVPA) had small biases (within 20% of the criterion mean) and the ICCs were excellent (0.82-0.98). Total MET-minutes were slightly underestimated by 9.3-17.1% and the ICCs were good (0.68-0.79). The standard deviations of the bias estimates were moderate-to-large relative to the means. The computer vision algorithms appeared to have acceptable sample-level validity (i.e., across a sample of time intervals) and are promising for automated ecological assessment of activity in open outdoor settings, but further development and testing is needed before such tools can be used in a diverse range of settings. PMID- 29194359 TI - Chikungunya Virus: Pathophysiology, Mechanism, and Modeling. AB - Chikungunya virus (CHIKV), a mosquito-transmitted alphavirus, is recurring in epidemic waves. In the past decade and a half, the disease has resurged in several countries around the globe, with outbreaks becoming increasingly severe. Though CHIKV was first isolated in 1952, there remain significant gaps in knowledge of CHIKV biology, pathogenesis, transmission, and mechanism. Diagnosis is largely simplified and based on symptoms, while treatment is supportive rather than curative. Here we present an overview of the disease, the challenges that lie ahead for future research, and what directions current studies are headed towards, with emphasis on improvement of current animal models and potential use of 3D models. PMID- 29194360 TI - The Modulation of NMDA and AMPA/Kainate Receptors by Tocotrienol-Rich Fraction and Alpha-Tocopherol in Glutamate-Induced Injury of Primary Astrocytes. AB - Astrocytes are known as structural and supporting cells in the central nervous system (CNS). Glutamate, as a main excitatory amino acid neurotransmitter in the mammalian central nervous system, can be excitotoxic, playing a key role in many chronic neurodegenerative diseases. The aim of the current study was to elucidate the potential of vitamin E in protecting glutamate-injured primary astrocytes. Hence, primary astrocytes were isolated from mixed glial cells of C57BL/6 mice by applying the EasySep(r) Mouse CD11b Positive Selection Kit, cultured in Dulbecco's modified Eagle medium (DMEM) and supplemented with special nutrients. The IC20 and IC50 values of glutamate, as well as the cell viability of primary astrocytes, were assessed with 100 ng/mL, 200 ng/mL, and 300 ng/mL of tocotrienol rich fraction (TRF) and alpha-tocopherol (alpha-TCP), as determined by an 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The mitochondrial membrane potential (MMP) detected in primary astrocytes was assessed with the same concentrations of TRF and alpha-TCP. The expression levels of the ionotropic glutamate receptor genes (Gria2, Grin2A, GRIK1) were independently determined using RT-PCR. The purification rate of astrocytes was measured by a flow-cytometer as circa 79.4%. The IC20 and IC50 values of glutamate were determined as 10 mM and 100 mM, respectively. Exposure to 100 mM of glutamate in primary astrocytes caused the inhibition of cell viability of approximately 64.75% and 61.10% in pre- and post-study, respectively (p < 0.05). Both TRF and alpha-TCP (at the lowest and highest concentrations, respectively) were able to increase the MMP to 88.46% and 93.31% pre-treatment, and 78.43% and 81.22% post-treatment, respectively. Additionally, the findings showed a similar pattern for the expression level of the ionotropic glutamate receptor genes. Increased extracellular calcium concentrations were also observed, indicating that the presence of vitamin E altered the polarization of astrocytes. In conclusion, alpha-TCP showed better recovery and prophylactic effects as compared to TRF in the pre-treatment of glutamate-injured primary astrocytes. PMID- 29194361 TI - Social Networks, Engagement and Resilience in University Students. AB - Analysis of social networks may be a useful tool for understanding the relationship between resilience and engagement, and this could be applied to educational methodologies, not only to improve academic performance, but also to create emotionally sustainable networks. This descriptive study was carried out on 134 university students. We collected the network structural variables, degree of resilience (CD-RISC 10), and engagement (UWES-S). The computer programs used were excel, UCINET for network analysis, and SPSS for statistical analysis. The analysis revealed results of means of 28.61 for resilience, 2.98 for absorption, 4.82 for dedication, and 3.13 for vigour. The students had two preferred places for sharing information: the classroom and WhatsApp. The greater the value for engagement, the greater the degree of centrality in the friendship network among students who are beginning their university studies. This relationship becomes reversed as the students move to later academic years. In terms of resilience, the highest values correspond to greater centrality in the friendship networks. The variables of engagement and resilience influenced the university students' support networks. PMID- 29194362 TI - The Small Regulatory RNA Spot42 Inhibits Indole Biosynthesis to Negatively Regulate the Locus of Enterocyte Effacement of Enteropathogenic Escherichia coli. AB - The locus of enterocyte effacement is necessary for enteropathogenic Escherichia coli (EPEC) to form attaching and effacing (A/E) lesions. A/E lesions are characterized by intimate bacterial adherence to intestinal cells and destruction of microvilli, which leads to diarrhea. Therefore, studies interrogating the regulation of the locus of enterocyte effacement (LEE) are critical for understanding the molecular epidemiology of EPEC infections and developing interventional strategies. Hitherto, most studies have centered on protein-based regulators, whereas the role of small regulatory RNAs remains underappreciated. Previously, we identified the first sRNAs-MgrR, RyhB, and McaS-that regulate the LEE of EPEC. This study was undertaken to identify additional sRNAs that impact the LEE. Our results suggest that the catabolite-responsive sRNA, Spot42, indirectly controls the LEE by inhibiting synthesis of its inducer, indole. Spot42 base-pairs with the tnaCAB mRNA and presumably destabilizes the transcript, thereby preventing expression of the regulatory and structural proteins that are involved in the import and hydrolysis of tryptophan into indole. The absence of intracellular indole leads to reduced transcription of the LEE1-encoded master transcriptional activator Ler, thereby maintaining the LEE in its silenced state and delaying A/E lesion morphogenesis. Our results highlight the importance of riboregulators that synchronize metabolic and virulence pathways in bacterial infection. PMID- 29194363 TI - The E3 Ubiquitin Ligase RNF7 Negatively Regulates CARD14/CARMA2sh Signaling. AB - The three CARD-containing MAGUK (CARMA) proteins function as scaffolding molecules that regulate activation of the pro-inflammatory transcription factor NF-kappaB. Recently, mutations in CARMA2 have been linked to psoriasis susceptibility due to their acquired altered capacity to activate NF-kappaB. By means of two-hybrid screening with yeast, we identified RING finger protein 7 (RNF7) as an interactor of CARMA2. We present evidence that RNF7 functions as a negative regulator of the NF-kappaB-activating capacity of CARMA2. Mechanistically, RNF7 influences CARMA2 signaling by regulating the ubiquitination state of MALT1 and the NF-kappaB-regulatory molecule NEMO. Interestingly, CARMA2short (CARMA2sh) mutants associated with psoriasis susceptibility escape the negative control exerted by RNF7. In conclusion, our findings identify a new mechanism through which the ability of CARMA2 to activate NF-kappaB is regulated, which could have significant implications for our understanding of why mutations of this protein trigger human psoriasis. PMID- 29194364 TI - Resveratrol Role in Autoimmune Disease-A Mini-Review. AB - Autoimmune diseases are still considered to be pressing concerns due the fact that they are leaders in death and disability causes worldwide. Resveratrol is a polyphenol derived from a variety of foods and beverages, including red grapes and red wine. Anti-inflammatory, antioxidant, and antiaging properties of resveratrol have been reported, and in some animal and human studies this compound reduced and ameliorated the progression of autoimmune diseases, such as rheumatoid arthritis, systemic lupus erythematosus, psoriasis, inflammatory bowel disease, and type 1 diabetes mellitus. Thus, this review aims to summarize and critically analyze the role of resveratrol in the modulation of several organ specific or systemic autoimmune diseases. PMID- 29194366 TI - Exploring the Impact of Food on the Gut Ecosystem Based on the Combination of Machine Learning and Network Visualization. AB - Prebiotics and probiotics strongly impact the gut ecosystem by changing the composition and/or metabolism of the microbiota to improve the health of the host. However, the composition of the microbiota constantly changes due to the intake of daily diet. This shift in the microbiota composition has a considerable impact; however, non-pre/probiotic foods that have a low impact are ignored because of the lack of a highly sensitive evaluation method. We performed comprehensive acquisition of data using existing measurements (nuclear magnetic resonance, next-generation DNA sequencing, and inductively coupled plasma-optical emission spectroscopy) and analyses based on a combination of machine learning and network visualization, which extracted important factors by the Random Forest approach, and applied these factors to a network module. We used two pteridophytes, Pteridium aquilinum and Matteuccia struthiopteris, for the representative daily diet. This novel analytical method could detect the impact of a small but significant shift associated with Matteuccia struthiopteris but not Pteridium aquilinum intake, using the functional network module. In this study, we proposed a novel method that is useful to explore a new valuable food to improve the health of the host as pre/probiotics. PMID- 29194367 TI - Safety Aspects of Bio-Based Nanomaterials. AB - Moving towards a bio-based and circular economy implies a major focus on the responsible and sustainable utilization of bio-resources. The emergence of nanotechnology has opened multiple possibilities, not only in the existing industrial sectors, but also for completely novel applications of nanoscale bio materials, the commercial exploitation of which has only begun during the last few years. Bio-based materials are often assumed not to be toxic. However, this pre-assumption is not necessarily true. Here, we provide a short overview on health and environmental aspects associated with bio-based nanomaterials, and on the relevant regulatory requirements. We also discuss testing strategies that may be used for screening purposes at pre-commercial stages. Although the tests presently used to reveal hazards are still evolving, regarding modifi-cations required for nanomaterials, their application is needed before the upscaling or commercialization of bio-based nanomaterials, to ensure the market potential of the nanomaterials is not delayed by uncertainties about safety issues. PMID- 29194368 TI - Vitamin D: Moving Forward to Address Emerging Science. AB - The science surrounding vitamin D presents both challenges and opportunities. Although many uncertainties are associated with the understandings concerning vitamin D, including its physiological function, the effects of excessive intake, and its role in health, it is at the same time a major interest in the research and health communities. The approach to evaluating and interpreting the available evidence about vitamin D should be founded on the quality of the data and on the conclusions that take into account the totality of the evidence. In addition, these activities can be used to identify critical data gaps and to help structure future research. The Office of Dietary Supplements (ODS) at the National Institutes of Health has as part of its mission the goal of supporting research and dialogues for topics with uncertain data, including vitamin D. This review considers vitamin D in the context of systematically addressing the uncertainty and in identifying research needs through the filter of the work of ODS. The focus includes the role of systematic reviews, activities that encompass considerations of the totality of the evidence, and collaborative activities to clarify unknowns or to fix methodological problems, as well as a case study using the relationship between cancer and vitamin D. PMID- 29194365 TI - The Role of Resveratrol in Cancer Therapy. AB - Abstract: Natural product compounds have recently attracted significant attention from the scientific community for their potent effects against inflammation driven diseases, including cancer. A significant amount of research, including preclinical, clinical, and epidemiological studies, has indicated that dietary consumption of polyphenols, found at high levels in cereals, pulses, vegetables, and fruits, may prevent the evolution of an array of diseases, including cancer. Cancer development is a carefully orchestrated progression where normal cells acquires mutations in their genetic makeup, which cause the cells to continuously grow, colonize, and metastasize to other organs such as the liver, lungs, colon, and brain. Compounds that modulate these oncogenic processes can be considered as potential anti-cancer agents that may ultimately make it to clinical application. Resveratrol, a natural stilbene and a non-flavonoid polyphenol, is a phytoestrogen that possesses anti-oxidant, anti-inflammatory, cardioprotective, and anti-cancer properties. It has been reported that resveratrol can reverse multidrug resistance in cancer cells, and, when used in combination with clinically used drugs, it can sensitize cancer cells to standard chemotherapeutic agents. Several novel analogs of resveratrol have been developed with improved anti-cancer activity, bioavailability, and pharmacokinetic profile. The current focus of this review is resveratrol's in vivo and in vitro effects in a variety of cancers, and intracellular molecular targets modulated by this polyphenol. This is also accompanied by a comprehensive update of the various clinical trials that have demonstrated it to be a promising therapeutic and chemopreventive agent. PMID- 29194369 TI - Elevated Systemic IL-6 Levels in Patients with Aneurysmal Subarachnoid Hemorrhage Is an Unspecific Marker for Post-SAH Complications. AB - Background: Aneurysmal subarachnoid hemorrhage (aSAH) is still a fatal and morbid disease, although bleeding aneurysms can be secured in almost all cases. Occurrence of post-SAH complications including cerebral vasospasm, delayed cerebral ischemia, hydrocephalus, epilepsy, and infections are the main determinants of clinical outcome. Hence, it is important to search for early predictors for specific post-SAH complications to treat these complications properly. Both cellular and molecular (cytokines) inflammation play a key role after aSAH during the phase of occurrence of post-SAH complications. Interleukin 6 (IL-6) is a well-known cytokine that has been extensively analyzed in cerebrospinal fluid (CSF) of patients after aSAH, but detailed studies exploring the role of systemic IL-6 in aSAH associated complications and its impact on early clinical outcome prediction are lacking. The current study aims to analyze the systemic IL-6 levels over two weeks after bleeding and its role in post-SAH complications. Methods: We recruited 80 aSAH patients prospectively who underwent peripheral venous blood withdrawal in serum gel tubes. The blood was centrifuged to harvest the serum, which was immediately frozen at -80 degrees C until analysis. Serum IL-6 levels were quantified using Immulite immunoassay system. Patient records including age, gender, post-SAH complications, aneurysm treatment, and clinical outcome (modified Rankin scale and Glasgow outcome scale) were retrieved to allow different subgroup analysis. Results: Serum IL-6 levels were significantly raised after aSAH compared to healthy controls over the first two weeks after hemorrhage. Serum IL-6 levels were found to be significantly elevated in aSAH patients presenting with higher Hunt and Hess grades, increasing age, and both intraventricular and intracerebral hemorrhage. Interestingly, serum IL-6 was also significantly raised in aSAH patients who developed seizures, cerebral vasospasm (CVS), and chronic hydrocephalus. IL-6 levels were sensitive to the development of infections and showed an increase in patients who developed pneumoniae. Intriguingly, we found a delayed increase in serum IL-6 in patients developing cerebral infarction. Finally, IL-6 levels were significantly higher in patients presenting with poor clinical outcome in comparison to good clinical outcome at discharge from hospital. Conclusion: Serum IL-6 levels were elevated early after aSAH and remained high over the two weeks after initial bleeding. Serum IL-6 was elevated in different aSAH associated complications, acting as a non-specific marker for post-SAH complications and an important biomarker for clinical outcome at discharge. PMID- 29194371 TI - In Vivo Imaging of Prostate Cancer Tumors and Metastasis Using Non-Specific Fluorescent Nanoparticles in Mice. AB - With the growing interest in the use of nanoparticles (NPs) in nanomedicine, there is a crucial need for imaging and targeted therapies to determine NP distribution in the body after systemic administration, and to achieve strong accumulation in tumors with low background in other tissues. Accumulation of NPs in tumors results from different mechanisms, and appears extremely heterogeneous in mice models and rather limited in humans. Developing new tumor models in mice, with their low spontaneous NP accumulation, is thus necessary for screening imaging probes and for testing new targeting strategies. In the present work, accumulation of LipImageTM 815, a non-specific nanosized fluorescent imaging agent, was compared in subcutaneous, orthotopic and metastatic tumors of RM1 cells (murine prostate cancer cell line) by in vivo and ex vivo fluorescence imaging techniques. LipImageTM 815 mainly accumulated in liver at 24 h but also in orthotopic tumors. Limited accumulation occurred in subcutaneous tumors, and very low fluorescence was detected in metastasis. Altogether, these different tumor models in mice offered a wide range of NP accumulation levels, and a panel of in vivo models that may be useful to further challenge NP targeting properties. PMID- 29194370 TI - Alternative Oral Agents in Prophylaxis and Therapy of Uterine Fibroids-An Up-to Date Review. AB - Uterine fibroids (UFs) are the most common tumors of the female genital tract. The effect of UFs on the quality of life and the overall cost of treatment are significant issues worldwide. Tumor size and location are the two specific factors which influence the occurrence of symptoms, the need for, and method of, treatment (some tumors require surgery while some can be treated with selected drugs). Primary prevention and treatment of early UF disease are worthy goals that might have a great impact on health care systems. Several treatments and prophylactic methods can be used in this endeavor. This publication presents current data about lesser-known substances which may have a beneficial effect on the treatment or prophylaxis of UFs and can be administered orally, serving as an alternative to (or complement of) surgery or selective progesterone receptor modulators (SPRMs). Early prevention and treatment of UFs in women from high-risk groups should be our priority. Innovative forms of UF management are under intensive investigation and may be promising options in the near future. Many of them evaluated vitamin D, paricalcitol, epigallocatechin gallate (EGCG), elagolix, aromatase inhibitors (AIs), and cabergoline and deemed them to be safe and effective. The next step in such projects should be properly constructed randomized control trials (RCTs), carried out by successive phases. PMID- 29194373 TI - Anti-Proliferative Activity of Triterpenoids and Sterols Isolated from Alstonia scholaris against Non-Small-Cell Lung Carcinoma Cells. AB - (1) Background: In China and South Asia, Alstonia scholaris (Apocynaceae) is an important medicinal plant that has been historically used in traditional ethnopharmacy to treat infectious diseases. Although various pharmacological activities have been reported, the anti-lung cancer components of A. scholaris have not yet been identified. The objective of this study is to evaluate the active components of the leaf extract of A. scholaris, and assess the anti proliferation effects of isolated compounds against non-small-cell lung carcinoma cells; (2) Methods: NMR was used to identify the chemical constitutes isolated from the leaf extract of A. scholaris. The anti-proliferative activity of compounds against non-small-cell lung carcinoma cells was assessed by 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay; (3) Results: Eight triterpenoids and five sterols were isolated from the hexane portion of A. scholaris, and structurally identified as: (1) ursolic acid, (2) oleanolic acid, (3) betulinic acid, (4) betulin, (5) 2beta,3beta,28-lup-20(29)-ene-triol, (6) lupeol, (7) beta-amyrin, (8) alpha-amyrin, (9) poriferasterol, (10) epicampesterol, (11) beta-sitosterol, (12) 6beta-hydroxy-4-stigmasten-3-one, and (13) ergosta-7,22-diene-3beta,5alpha,6beta-triol. Compound 5 was isolated from a plant source for the first time. In addition, compounds 9, 10, 12, and 13 were also isolated from A. scholaris for the first time. Ursolic acid, betulinic acid, betulin, and 2beta,3beta,28-lup-20(29)-ene-triol showed anti-proliferative activity against NSCLC, with IC50 of 39.8, 40.1, 240.5 and 172.6 MUM, respectively.; (4) Conclusion: These findings reflect that pentacyclic triterpenoids are the anti-lung cancer chemicals in A. scholaris. The ability of ursolic acid, betulinic acid, betulin, and 2beta,3beta,28-lup-20(29)-ene-triol to inhibit the proliferative activity of NSCLC can constitute a valuable group of therapeutic agents in the future. PMID- 29194372 TI - What Is Our Current Understanding of PrPSc-Associated Neurotoxicity and Its Molecular Underpinnings? AB - The prion diseases are a collection of fatal, transmissible neurodegenerative diseases that cause rapid onset dementia and ultimately death. Uniquely, the infectious agent is a misfolded form of the endogenous cellular prion protein, termed PrPSc. Despite the identity of the molecular agent remaining the same, PrPSc can cause a range of diseases with hereditary, spontaneous or iatrogenic aetiologies. However, the link between PrPSc and toxicity is complex, with subclinical cases of prion disease discovered, and prion neurodegeneration without obvious PrPSc deposition. The toxic mechanisms by which PrPSc causes the extensive neuropathology are still poorly understood, although recent advances are beginning to unravel the molecular underpinnings, including oxidative stress, disruption of proteostasis and induction of the unfolded protein response. This review will discuss the diseases caused by PrPSc toxicity, the nature of the toxicity of PrPSc, and our current understanding of the downstream toxic signaling events triggered by the presence of PrPSc. PMID- 29194374 TI - Subcellular Interactions during Vascular Morphogenesis in 3D Cocultures between Endothelial Cells and Fibroblasts. AB - BACKGROUND: Increasing the complexity of in vitro systems to mimic three dimensional tissues and the cellular interactions within them will increase the reliability of data that were previously collected with in vitro systems. In vivo vascularization is based on complex and clearly defined cell-matrix and cell-cell interactions, where the extracellular matrix (ECM) seems to play a very important role. The aim of this study was to monitor and visualize the subcellular and molecular interactions between endothelial cells (ECs), fibroblasts, and their surrounding microenvironment during vascular morphogenesis in a three-dimensional coculture model. METHODS: Quantitative and qualitative analyses during the generation of a coculture tissue construct consisting of endothelial cells and fibroblasts were done using transmission electron microscopy and immunohistochemistry. RESULTS: Dynamic interactions were found in cocultures between ECs, between fibroblasts (FBs), between ECs and FBs, and between the cells and the ECM. Microvesicles were involved in intercellular information transfer. FBs took an active and physical part in the angiogenesis process. The ECM deposited by the cells triggered endothelial angiogenic activity. Capillary like tubular structures developed and matured. Moreover, some ECM assembled into a basement membrane (BM) having three different layers equivalent to those seen in vivo. Finally, the three-dimensional in vitro construct mirrored the topography of histological tissue sections. CONCLUSION: Our results visualize the importance of the physical contact between all cellular and acellular components of the cocultures.

However, various agricultural practices on farmland carbon sequestration usually have a major impact on greenhouse gas (GHG) emissions. It is very important to accurately quantify the effect of agricultural practices. This study developed a platform-the Denitrification Decomposition (DNDC) online model-for simulating and evaluating the agricultural carbon sequestration and emission mitigation based on the scientific process of the DNDC model, which is widely used in the simulation of soil carbon and nitrogen dynamics. After testing the adaptability of the platform on two sampling fields, it turned out that the simulated values matched the measured values well for crop yields and GHG emissions. We used the platform to estimate the effect of three carbon sequestration practices in a sampling field: nitrogen fertilization reduction, straw residue and midseason drainage. The results indicated the following: (1) moderate decrement of the nitrogen fertilization in the sampling field was able to decrease the N2O emission while maintaining the paddy rice yield; (2) ground straw residue had almost no influence on paddy rice yield, but the CH4 emission and the surface SOC concentration increased along with the quantity of the straw residue; (3) compared to continuous flooding, midseason drainage would not decrease the paddy rice yield and could lead to a drop in CH4 emission. Thus, this study established the DNDC online model, which is able to serve as a reference and support for the study and evaluation of the effects of agricultural practices on agricultural carbon sequestration and GHG emissions mitigation in China.

AB - Reported for its antioxidant, anti-inflammatory and non-toxicity properties, the hot water extract of Picea mariana bark was demonstrated to contain highly valuable bioactive polyphenols. In order to improve the recovery of these molecules, an optimization of the extraction was performed using water. Several extraction parameters were tested and extracts obtained analyzed both in terms of relative amounts of different phytochemical families and of individual molecules concentrations. As a result, low temperature (80 degrees C) and low ratio of bark/water (50 mg/mL) were determined to be the best parameters for an efficient polyphenol extraction and that especially for low molecular mass polyphenols. These were identified as stilbene monomers and derivatives, mainly stilbene glucoside isorhapontin (up to 12.0% of the dry extract), astringin (up to 4.6%), resveratrol (up to 0.3%), isorhapontigenin (up to 3.7%) and resveratrol glucoside piceid (up to 3.1%) which is here reported for the first time for Picea mariana. New stilbene derivatives, piceasides O and P were also characterized herein as new isorhapontin dimers. This study provides novel information about the optimal extraction of polyphenols from black spruce bark, especially for highly bioactive stilbenes including the trans-resveratrol.

AB - Pharmaceutical approaches based on nanotechnologies and the development of eye drops composed of the mucoadhesive polymers chitosan and hyaluronic acid are emerging strategies for the efficient treatment of ocular diseases. These innovative nanoparticulate systems aim to increase drugs' bioavailability at the ocular surface. For the successful development of these systems, the evaluation of mucoahesiveness (the interaction between the ocular delivery system and mucins present on the eye) is of utmost importance. In this context, the aim of the present work was to investigate the mucoadhesivity of a novel nanoparticle eye drop formulation containing an antibiotic (ceftazidime) intended to treat eye infections. Eye drop formulations comprised a polymer (hydroxypropyl) methyl cellulose (HPMC) 0.75% (w/v) in an isotonic solution incorporating chitosan/sodium tripolyphosphate (TPP)-hyaluronic acid-based nanoparticles containing ceftazidime. The viscosity of the nanoparticles, and the gels incorporating the nanoparticles were characterized in contact with mucin at different mass ratios, allowing the calculation of the rheological synergism parameter (?eta). Results showed that at different nanoparticle eye formulation:mucin weight ratios, a minimum in viscosity occurred which resulted in a negative rheological synergism. Additionally, the results highlighted the mucoadhesivity of the novel ocular formulation and its ability to interact with the ocular surface, thus increasing the drug residence time in the eye. Moreover, the in vitro release and permeation studies showed a prolonged drug release profile from the chitosan/TPP-hyaluronic acid nanoparticles gel formulation. Furthermore, the gel formulations were not cytotoxic on ARPE-19 and HEK293T cell lines, evaluated by the metabolic and membrane integrity tests. The formulation was stable and the drug active, as shown by microbiological studies. In conclusion, chitosan/TPP-hyaluronic acid nanoparticle eye drop formulations are a promising platform for ocular drug delivery with enhanced mucoadhesive properties.

AB - Secretion of extracellular vesicles (EVs) is a common feature of both eukaryotic and prokaryotic cells. Isolated EVs have been shown to contain different types of molecules, including proteins and nucleic acids, and are reported to be key players in intercellular communication. Little is known, however, of EV secretion in fish, or the effect of infection on EV release and content. In the present study, EVs were isolated from the serum of healthy and Piscirickettsia salmonis infected Atlantic salmon in order to evaluate the effect of infection on EV secretion. P. salmonis is facultative intracellular bacterium that causes a systemic infection disease in farmed salmonids. EVs isolated from both infected and non-infected fish had an average diameter of 230-300 nm, as confirmed by transmission electron microscopy, nanoparticle tracking, and flow cytometry. Mass spectrometry identified 180 proteins in serum EVs from both groups of fish. Interestingly, 35 unique proteins were identified in serum EVs isolated from the fish infected with P. salmonis. These unique proteins included proteasomes subunits, granulins, and major histocompatibility class I and II. Our results suggest that EV release could be part of a mechanism in which host stimulatory molecules are released from infected cells to promote an immune response. PMID- 29194380 TI - Effect of Marine-Derived Ice-Binding Proteins on the Cryopreservation of Marine Microalgae. AB - Ice-binding protein (IBPs) protect cells from cryo-injury during cryopreservation by inhibiting ice recrystallization (IR), which is a main cause of cell death. In the present study, we employed two IBPs, one, designated LeIBP from Arctic yeast, and the other, designated FfIBP from Antarctic sea ice bacterium, in the cryopreservation of three economically valuable marine microalgae, Isochrysis galbana, Pavlova viridis, and Chlamydomonas coccoides. Both of the IBPs showed IR inhibition in f/2 medium containing 10% DMSO, indicating that they retain their function in freezing media. Microalgal cells were frozen in 10% DMSO with or without IBP. Post-thaw viability exhibited that the supplementation of IBPs increased the viability of all cryopreserved cells. LeIBP was effective in P. viridis and C. coccoides, while FfIBP was in I. galbana. The cryopreservative effect was more drastic with P. viridis when 0.05 mg/mL LeIBP was used. These results clearly demonstrate that IBPs could improve the viability of cryopreserved microalgal cells. PMID- 29194381 TI - Chemical Diversity from a Chinese Marine Red Alga, Symphyocladia latiuscula. AB - This study describes an investigation into secondary metabolites that are produced by a marine red alga, Symphyocladia latiuscula, which was collected from coastal waters off Qingdao, China. A combination of normal, reversed phase, and gel chromatography was used to isolate six citric acid derived natural products, aconitates A-F (1-6), together with two known and ten new polybrominated phenols, symphyocladins C/D (7a/b), and symphyocladins H-Q (8a/b, 9a/b and 10-15), respectively. Structure elucidation was achieved by detailed spectroscopic (including X-ray crystallographic) analysis. We propose a plausible and convergent biosynthetic pathway involving a key quinone methide intermediate, linking aconitates and symphyocladins.

AB - Graphene aerogels (GAs) have attracted extensive interest in diverse fields, owing to their ultrahigh surface area, low density and decent electrical conductivity. However, the undesirable thermal conductivity of GAs may limit their applications in energy storage devices. Here, we report a facile hydrothermal method to modulate both the electrical and thermal properties of GAs by including bulk molybdenum disulfide (MoS2). It was found that MoS2 can help to reduce the size of graphene sheets and improve their dispersion, leading to the uniform porous micro-structure of GAs. The electrical measurement showed that the electrical conductivity of GAs could be decreased by 87% by adding 0.132 vol % of MoS2. On the contrary, the thermal conductivity of GAs could be increased by ~51% by including 0.2 vol % of MoS2. The quantitative investigation demonstrated that the effective medium theories (EMTs) could be applied to predict the thermal conductivity of composite GAs. Our findings indicated that the electrical and thermal properties of GAs can be tuned for the applications in various fields.

One of the most important Candida spp. virulence factors is the ability to form biofilms, which are extremely refractory to antimicrobial therapy and very difficult to treat with the traditional antifungal therapies. It is known that the prophylaxis or treatment of a systemic candidiasis are recurrently taken without considering the possibility of a Candida spp. biofilm related infections. Therefore, it is important to assess the effectiveness of the available drugs and which formulations have the best performance in these specific infections. METHODS: 24-h-biofilms of four Candida spp. and their response to two amphotericin B (AmB) pharmaceutical formulations (liposomal and deoxycholate) were evaluated. RESULTS: generally, Candida glabrata was the less susceptible yeast species to both AmBs. MBECs revealed that it is therapeutically more appealing to use AmB-L than AmB-Deox for all Candida spp. biofilms, since none of the determined concentrations of AmB-L reached 10% of the maximum daily dose, but both formulations showed a very good capacity in the biomass reduction. CONCLUSIONS: the liposomal formulation presents better performance in the eradication of the biofilm cells for all the species in comparison with the deoxycholate formulation. PMID- 29194384 TI - PCA Based Stress Monitoring of Cylindrical Specimens Using PZTs and Guided Waves. AB - Since mechanical stress in structures affects issues such as strength, expected operational life and dimensional stability, a continuous stress monitoring scheme is necessary for a complete integrity assessment. Consequently, this paper proposes a stress monitoring scheme for cylindrical specimens, which are widely used in structures such as pipelines, wind turbines or bridges. The approach consists of tracking guided wave variations due to load changes, by comparing wave statistical patterns via Principal Component Analysis (PCA). Each load scenario is projected to the PCA space by means of a baseline model and represented using the Q-statistical indices. Experimental validation of the proposed methodology is conducted on two specimens: (i) a 12.7 mm ( 1 / 2 " ) diameter, 0.4 m length, AISI 1020 steel rod, and (ii) a 25.4 mm ( 1 " ) diameter, 6m length, schedule 40, A-106, hollow cylinder. Specimen 1 was subjected to axial loads, meanwhile specimen 2 to flexion. In both cases, simultaneous longitudinal and flexural guided waves were generated via piezoelectric devices (PZTs) in a pitch-catch configuration. Experimental results show the feasibility of the approach and its potential use as in-situ continuous stress monitoring application.

AB - In order to develop film electrodes for the surface acoustic wave (SAW) devices operating in harsh high-temperature environments, novel Al2O3/Pt/ZnO/Al2O3 multilayered film electrodes were prepared by laser molecular beam epitaxy (LMBE) at 150 degrees C. The first Al2O3 layer was used as a barrier layer to prevent the diffusion of Ga, La, and Si atoms from the La3Ga5SiO14 (LGS) substrate to the film electrode and thus improved the crystalline quality of ZnO and Pt films. It was found that the resistance of the Al2O3/Pt/ZnO/Al2O3 electrode did not vary up to a temperature of 1150 degrees C, suggesting a high reliability of electrode under harsh high-temperature environments. The mechanism of the stable resistance of the Al2O3/Pt/ZnO/Al2O3 film electrodes at high temperature was investigated by analyzing its microstructure. The proposed Al2O3/Pt/ZnO/Al2O3 film electrode has great potential for application in high-temperature SAW devices. PMID- 29194386 TI - Hierarchical Control of Nitrite Respiration by Transcription Factors Encoded within Mobile Gene Clusters of Thermus thermophilus. AB - Denitrification in Thermus thermophilus is encoded by the nitrate respiration conjugative element (NCE) and nitrite and nitric oxide respiration (nic) gene clusters. A tight coordination of each cluster's expression is required to maximize anaerobic growth, and to avoid toxicity by intermediates, especially nitric oxides (NO). Here, we study the control of the nitrite reductases (Nir) and NO reductases (Nor) upon horizontal acquisition of the NCE and nic clusters by a formerly aerobic host. Expression of the nic promoters PnirS, PnirJ, and PnorC, depends on the oxygen sensor DnrS and on the DnrT protein, both NCE encoded. NsrR, a nic-encoded transcription factor with an iron-sulfur cluster, is also involved in Nir and Nor control. Deletion of nsrR decreased PnorC and PnirJ transcription, and activated PnirS under denitrification conditions, exhibiting a dual regulatory role never described before for members of the NsrR family. On the basis of these results, a regulatory hierarchy is proposed, in which under anoxia, there is a pre-activation of the nic promoters by DnrS and DnrT, and then NsrR leads to Nor induction and Nir repression, likely as a second stage of regulation that would require NO detection, thus avoiding accumulation of toxic levels of NO. The whole system appears to work in remarkable coordination to function only when the relevant nitrogen species are present inside the cell. PMID- 29194387 TI - Preparation and Characterization of Cabamazepine Cocrystal in Polymer Solution. AB - In this study, we attempted to prepare carbamazepine (CBZ) cocrystal through the solution method in ethanol-water solvent mixture (volume ratio 1:1) and polyvinyl pyrrolidone (PVP) solution. Nicotinamide (NIC) and saccharin (SAC) were selected as cocrystal coformers. Cocrystal screening products were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), and Powder X-ray Diffraction (PXRD) techniques. Characterization results show that in ethanol-water solvent mixture, pure CBZ-NIC cocrystal can be prepared, while CBZ-SAC cocrystal cannot be obtained. The addition of PVP can inhibit CBZ-NIC cocrystal formation and facilitate CBZ-SAC cocrystal formation. PMID- 29194388 TI - Antinociceptive Activity of Macaranga denticulata Muell. Arg. (Family: Euphorbiaceae): In Vivo and In Silico Studies. AB - Background: The present study was conducted to investigate the antinociceptive activity of methanol extract of Macaranga denticulata (Met.MD) in an animal model, followed by molecular docking analysis. Methods: Antinociceptive activity was determined by acetic acid-induced writhing and formalin-induced licking test in mice. Then, molecular docking study was performed to identify compounds having maximum activity against the COX-1 enzyme using Schrodinger Maestro (version 10.1) to determine docking fitness. Results: A preliminary phytochemical analysis of Met.MD revealed that it contained alkaloids, carbohydrates, phenols, flavonoids, tannins, and terpenoids. Met.MD exhibited a dose-dependent and statistically significant antinociceptive activity in the acetic acid and formalin test at the doses of 200 and 400 mg/kg. In addition, our docking study showed that macarangin had the best fitness score of -5.81 with COX-1 enzyme among six major compounds of M. denticulata. Conclusions: Results of the present study confirmed the potential antinociceptive activity of M. denticulata leaf extract in both in vivo and in silico models. PMID- 29194389 TI - Variation in CYP2A6 Activity and Personalized Medicine. AB - The cytochrome P450 2A6 (CYP2A6) enzyme metabolizes several clinically relevant substrates, including nicotine-the primary psychoactive component in cigarette smoke. The gene that encodes the CYP2A6 enzyme is highly polymorphic, resulting in extensive interindividual variation in CYP2A6 enzyme activity and the rate of metabolism of nicotine and other CYP2A6 substrates including cotinine, tegafur, letrozole, efavirenz, valproic acid, pilocarpine, artemisinin, artesunate, SM 12502, caffeine, and tyrosol. CYP2A6 expression and activity are also impacted by non-genetic factors, including induction or inhibition by pharmacological, endogenous, and dietary substances, as well as age-related changes, or interactions with other hepatic enzymes, co-enzymes, and co-factors. As variation in CYP2A6 activity is associated with smoking behavior, smoking cessation, tobacco-related lung cancer risk, and with altered metabolism and resulting clinical responses for several therapeutics, CYP2A6 expression and enzyme activity is an important clinical consideration. This review will discuss sources of variation in CYP2A6 enzyme activity, with a focus on the impact of CYP2A6 genetic variation on metabolism of the CYP2A6 substrates. PMID- 29194390 TI - Thyroid Disrupting Chemicals. AB - Endocrine disruptor compounds are exogenous agents able to interfere with a gland function, exerting their action across different functional passages, from the synthesis to the metabolism and binding to receptors of the hormone produced. Several issues, such as different levels and time of exposure and different action across different ages as well as gender, make the study of endocrine disruptors still a challenge. The thyroid is very sensitive to the action of disruptors, and considering the importance of a correct thyroid function for physical and cognitive functioning, addressing this topic should be considered a priority. In this review, we examined the most recent studies, many of them concentrating on maternal and child exposure, conducted to assess the impact of industrial chemicals which showed an influence on thyroid function. So far, the number of studies conducted on that topic is not sufficient to provide solid conclusions and lead to homogeneous guidelines. The lack of uniformity is certainly due to differences in areas and populations examined, the different conditions of exposures and the remarkable inter-subject variability. Nonetheless, the European Commission for Health and Food Safety is implementing recommendations to ensure that substances identified as endocrine disruptors will be withdrawn from the market. PMID- 29194391 TI - Impaired Osteogenesis of Disease-Specific Induced Pluripotent Stem Cells Derived from a CFC Syndrome Patient. AB - Cardiofaciocutaneous (CFC) syndrome is a rare genetic disorder caused by mutations in the extracellular signal-regulated kinase (ERK) signaling. However, little is known about how aberrant ERK signaling is associated with the defective bone development manifested in most CFC syndrome patients. In this study, induced pluripotent stem cells (iPSCs) were generated from dermal fibroblasts of a CFC syndrome patient having rapidly accelerated fibrosarcoma kinase B (BRAF) gain-of function mutation. CFC-iPSCs were differentiated into mesenchymal stem cells (CFC MSCs) and further induced to osteoblasts in vitro. The osteogenic defects of CFC MSCs were revealed by alkaline phosphatase activity assay, mineralization assay, quantitative real-time polymerase chain reaction (qRT-PCR), and western blotting. Osteogenesis of CFC-MSCs was attenuated compared to wild-type (WT)-MSCs. In addition to activated ERK signaling, increased p-SMAD2 and decreased p-SMAD1 were observed in CFC-MSCs during osteogenesis. The defective osteogenesis of CFC-MSCs was rescued by inhibition of ERK signaling and SMAD2 signaling or activation of SMAD1 signaling. Importantly, activation of ERK signaling and SMAD2 signaling or inhibition of SMAD1 signaling recapitulated the impaired osteogenesis in WT-MSCs. Our findings indicate that SMAD2 signaling and SMAD1 signaling as well as ERK signaling are responsible for defective early bone development in CFC syndrome, providing a novel insight on the pathological mechanism and therapeutic targets. PMID- 29194392 TI - A Cluster Randomized Trial to Promote Healthy Menu Items for Children: The Kids' Choice Restaurant Program. AB - Evidence indicates that restaurant-based interventions have the potential to promote healthier purchasing and improve the nutrients consumed. This study adds to this body of research by reporting the results of a trial focused on promoting the sale of healthy child menu items in independently owned restaurants. Eight pair-matched restaurants that met the eligibility criteria were randomized to a menu-only versus a menu-plus intervention condition. Both of the conditions implemented new healthy child menu items and received support for implementation for eight weeks. The menu-plus condition also conducted a marketing campaign involving employee trainings and promotional materials. Process evaluation data captured intervention implementation. Sales of new and existing child menu items were tracked for 16 weeks. Results indicated that the interventions were implemented with moderate to high fidelity depending on the component. Sales of new healthy child menu items occurred immediately, but decreased during the post intervention period in both conditions. Sales of existing child menu items demonstrated a time by condition effect with restaurants in the menu-plus condition observing significant decreases and menu-only restaurants observing significant increases in sales of existing child menu items. Additional efforts are needed to inform sustainable methods for improving access to healthy foods and beverages in restaurants. PMID- 29194393 TI - Developing a Novel Parameter Estimation Method for Agent-Based Model in Immune System Simulation under the Framework of History Matching: A Case Study on Influenza A Virus Infection. AB - Since they can provide a natural and flexible description of nonlinear dynamic behavior of complex system, Agent-based models (ABM) have been commonly used for immune system simulation. However, it is crucial for ABM to obtain an appropriate estimation for the key parameters of the model by incorporating experimental data. In this paper, a systematic procedure for immune system simulation by integrating the ABM and regression method under the framework of history matching is developed. A novel parameter estimation method by incorporating the experiment data for the simulator ABM during the procedure is proposed. First, we employ ABM as simulator to simulate the immune system. Then, the dimension-reduced type generalized additive model (GAM) is employed to train a statistical regression model by using the input and output data of ABM and play a role as an emulator during history matching. Next, we reduce the input space of parameters by introducing an implausible measure to discard the implausible input values. At last, the estimation of model parameters is obtained using the particle swarm optimization algorithm (PSO) by fitting the experiment data among the non implausible input values. The real Influeza A Virus (IAV) data set is employed to demonstrate the performance of our proposed method, and the results show that the proposed method not only has good fitting and predicting accuracy, but it also owns favorable computational efficiency. PMID- 29194394 TI - Theoretical Study of ClOO + NO Reaction: Mechanism and Kinetics. AB - Theoretical investigations are performed on mechanism and kinetics of the reaction of halogen peroxy radical ClOO with NO radical. The electronic structure information for both of the singlet and triplet potential energy surfaces (PESs) is obtained at the MP2/6-311 + G(2df) level of theory, and the single-point energies are refined by the CCSD(T)/6-311 + G(2df) level. The rate constants for various product channels of the reaction in the pressure range of 1-7600 Torr are predicted. The main results are as follows: On the singlet surface, the addition elimination mechanism is the most important. First, the N atom of the NO radical can attack the O atom of the ClOO radical to form an energy-riched intermediate IM1 ClOONOtp (21.3 kcal/mol) barrierlessly, then IM1 could isomerizes to IM2 ClOONOcp (22.1 kcal/mol) via a low energy barrier. Both IM1 and IM2 can dissociate to the primary product P1 ClNO + 1O2 and the secondary product P2 ClO + NO2. On the triplet surface, the direct Cl-abstraction reaction is the most feasible pathway. The Cl-abstraction can take place via a van der Waals complex, 3IM1 ONClOO (4.1 kcal/mol), then it fragments readily to give P1' ClNO + 3O2 with a small barrier. The kinetic calculations show that at low temperatures, the singlet bimolecular product P1 is the primary product, while at high temperatures, the triplet product P1' becomes the primary one; only at high pressures and low temperatures, the unimolecular products IM1 and IM2 can be found with quite small yields. At experimentally measured temperature 213 K, ClNO is the primary product in the whole pressure range, which is consistent with the previous experiment. The present study may be useful for further experimental studies for the title reaction. PMID- 29194395 TI - Efficient Removal of Tetracycline from Aqueous Media with a Fe3O4 Nanoparticles@graphene Oxide Nanosheets Assembly. AB - A readily separated composite was prepared via direct assembly of Fe3O4 magnetic nanoparticles onto the surface of graphene oxide (GO) (labeled as Fe3O4@GO) and used as an adsorbent for the removal of tetracycline (TC) from wastewater. The effects of external environmental conditions, such as pH, ionic strength, humic acid (HA), TC concentration, and temperature, on the adsorption process were studied. The adsorption data were analyzed by kinetics and isothermal models. The results show that the Fe3O4@GO composite has excellent sorptive properties and can efficiently remove TC. At low pH, the adsorption capacity of Fe3O4@GO toward TC decreases slowly with increasing pH value, while the adsorption capacity decreases rapidly at higher pH values. The ionic strength has insignificant effect on TC adsorption. The presence of HA affects the affinity of Fe3O4@GO to TC. The pseudo-second-order kinetics model and Langmuir model fit the adsorption data well. When the initial concentration of TC is 100 mg/L, a slow adsorption process dominates. Film diffusion is the rate limiting step of the adsorption. Importantly, Fe3O4@GO has good regeneration performance. The above results are of great significance to promote the application of Fe3O4@GO in the treatment of antibiotic wastewater. PMID- 29194396 TI - Aquaporins during Pregnancy: Their Function and Significance. AB - Water is the major component of cells and tissues, and the movement of water across the cell membrane is a fundamental property of life. Until the discovery of the first water channel, aquaporin, it was long assumed that the transport of water was due to simple diffusion through the lipid bilayer membrane that encloses cells. Aquaporin (AQP) molecules were first discovered in the human uterus in 1994, and since then several studies have investigated these channels in the female reproductive system. The expressions of AQPs have been proven in the reproductive system. Their levels are altered during the implantation process, both in the uterus and the fetal cells, and participate in the control of the flow of amniotic fluid. They seem to be very important for the normal placental functions. AQPs are present during parturition, participating in the control of pregnant myometrial contractions and cervical ripening. However, most of the physiological and regulatory roles of AQPs are not clarified in the reproductive tract. Furthermore, no satisfactory knowledge is available about their sensitivities to different drugs. AQP-selective ligands may contribute to the development of new drug candidates and the therapy of several reproductive disorders.

AB - Pyrrosiae Folium (PF) is a commonly used Chinese herb medicine originating from three Pyrrosia species for the treatment of urinary infection and urolithiasis. According to Chinese medicine practice, different specie origins led to some variations in the therapeutic effects of PF. To ensure the safety and efficacy of PF in clinical practice, it is necessary to establish a reliable and integrative method to distinguish PF occurring from the three species. In the present paper, a HPLC-DAD method was developed and applied to simultaneously analyze five major compounds in PF. Afterwards, multivariate statistical analyses including principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were applied for specie discrimination and integrative quality evaluation based on quantitative data. The chemical determination and pattern recognition results of 35 batches of PF samples indicated that PF samples from three species showed different chemical profiles and could be discriminated clearly. In conclusion, the present method is rapid and reliable for the quality assessment and species discrimination of PF. PMID- 29194399 TI - QNA-Based Prediction of Sites of Metabolism. AB - Metabolism of xenobiotics (Greek xenos: exogenous substances) plays an essential role in the prediction of biological activity and testing for the subsequent research and development of new drug candidates. Integration of various methods and techniques using different computational and experimental approaches is one of the keys to a successful metabolism prediction. While multiple structure-based and ligand-based approaches to metabolism prediction exist, the most important problem arises at the first stage of metabolism prediction: detection of the sites of metabolism (SOMs). In this paper, we describe the application of Quantitative Neighborhoods of Atoms (QNA) descriptors for prediction of the SOMs using potential function method, as well as several different machine learning techniques: naive Bayes, random forest classifier, multilayer perceptron with back propagation and convolutional neural networks, and deep neural networks. PMID- 29194398 TI - Synthesis of Rhizobial Exopolysaccharides and Their Importance for Symbiosis with Legume Plants. AB - Rhizobia dwell and multiply in the soil and represent a unique group of bacteria able to enter into a symbiotic interaction with plants from the Fabaceae family and fix atmospheric nitrogen inside de novo created plant organs, called nodules. One of the key determinants of the successful interaction between these bacteria and plants are exopolysaccharides, which represent species-specific homo- and heteropolymers of different carbohydrate units frequently decorated by non carbohydrate substituents. Exopolysaccharides are typically built from repeat units assembled by the Wzx/Wzy-dependent pathway, where individual subunits are synthesized in conjunction with the lipid anchor undecaprenylphosphate (und-PP), due to the activity of glycosyltransferases. Complete oligosaccharide repeat units are transferred to the periplasmic space by the activity of the Wzx flippase, and, while still being anchored in the membrane, they are joined by the polymerase Wzy. Here we have focused on the genetic control over the process of exopolysaccharides (EPS) biosynthesis in rhizobia, with emphasis put on the recent advancements in understanding the mode of action of the key proteins operating in the pathway. A role played by exopolysaccharide in Rhizobium-legume symbiosis, including recent data confirming the signaling function of EPS, is also discussed. PMID- 29194400 TI - Evidence of Biomass Smoke Exposure as a Causative Factor for the Development of COPD. AB - Chronic obstructive pulmonary disease (COPD) is a progressive disease of the lungs characterised by chronic inflammation, obstruction of airways, and destruction of the parenchyma (emphysema). These changes gradually impair lung function and prevent normal breathing. In 2002, COPD was the fifth leading cause of death, and is estimated by the World Health Organisation (WHO) to become the third by 2020. Cigarette smokers are thought to be the most at risk of developing COPD. However, recent studies have shown that people with life-long exposure to biomass smoke are also at high risk of developing COPD. Most common in developing countries, biomass fuels such as wood and coal are used for cooking and heating indoors on a daily basis. Women and children have the highest amounts of exposures and are therefore more likely to develop the disease. Despite epidemiological studies providing evidence of the causative relationship between biomass smoke and COPD, there are still limited mechanistic studies on how biomass smoke causes, and contributes to the progression of COPD. This review will focus upon why biomass fuels are used, and their relationship to COPD. It will also suggest methodological approaches to model biomass exposure in vitro and in vivo. PMID- 29194402 TI - Nutrition in the First 1000 Days: Ten Practices to Minimize Obesity Emerging from Published Science. AB - The prevalence of childhood overweight and obesity has increased in most countries the last decades. Considering this in a simplistic way, we can say that obesity is the result of an imbalance between energy intake and energy expenditure. Moreover, the environment from conception to childhood could influence the child's future health. The first 1000 days of life start with woman's pregnancy, and offer a unique window of opportunity to contribute to obesity prevention. In light of the actual literature, the aim of our article is to discuss a proposal of 10 good practices to minimize obesity in the first 1000 days emerging from published science. (1) Both the mother's and the father's behaviors are important. A balanced diet with appropriate fat and protein intake, and favoring fruits and vegetables, is recommended for both parents during the conception period and pregnancy. Furthermore, overweight/obese women who are planning to become pregnant should reduce their weight before conception. (2) During pregnancy, at birth, and during early life, body composition measurements are crucial to monitor the baby's growth. (3) Exclusive breastfeeding is recommended at the beginning of life until six months of age. (4) Four to six months of age is the optimal window to introduce complementary feeding. Until one year of age, breast milk or follow-on/commercial formula is the main recommended feeding source, and cow's milk should be avoided until one year of age. (5) Fruit and vegetable introduction should begin early. Daily variety, diversity in a meal, and repeated exposure to the food, up to eight times, are efficient strategies to increase acceptance of food not well accepted at first. There is no need to add sugar, salt, or sugary fluids to the diet. (6) Respect the child's appetite and avoid coercive "clean your plate" feeding practices. Adapt the portion of food and don't use food as reward for good behavior. (7) Limit animal protein intake in early life to reduce the risk of an early adiposity rebound. Growing-up milk for children between one and three years of age should be preferred to cow's milk, in order to limit intake and meet essential fatty acid and iron needs. (8) The intake of adequate fat containing essential fatty acids should be promoted. (9) Parents should be role models when feeding, with TV and other screens turned-off during meals. (10) Preventive interventions consisting of promoting physical activity and sufficient time dedicated to sleep should be employed. In fact, short sleep duration may be associated with increased risk of developing obesity. Based on literature reviews, and given the suggestions described in this manuscript, concerted public health efforts are needed to achieve the healthy objectives for obesity and nutrition, and to fight the childhood obesity epidemic.

AB - Two new natural products, micropeptin TR1058 (1) and aeruginosin TR642 (2), were isolated from the hydrophilic extract of bloom material of Microcystis sp. collected from the Timurim water reservoir in Israel. The structures of compounds 1 and 2 were determined using 1D and 2D NMR spectroscopy and HR ESI MS and MS/MS techniques. Micropeptin TR1058 (1) was extremely unstable under the isolation conditions, and several degradation products were identified. NMR analysis of aeruginosin TR642 (2) revealed a mixture of eight isomers, and elucidation of its structure was challenging. Aeruginosin TR642 contains a 4,5-didehydroaraginal subunit that has not been described before. Micropeptin TR1058 (1) inhibited chymotrypsin with an IC50 of 6.78 uM, and aeruginosin TR642 (2) inhibited trypsin and thrombin with inhibition concentration (IC50) values of 3.80 and 0.85 uM, respectively. The structures and biological activities of the new compounds are discussed. PMID- 29194401 TI - Drug Resistance Driven by Cancer Stem Cells and Their Niche. AB - Drug resistance represents one of the greatest challenges in cancer treatment. Cancer stem cells (CSCs), a subset of cells within the tumor with the potential for self-renewal, differentiation and tumorigenicity, are thought to be the major cause of cancer therapy failure due to their considerable chemo- and radioresistance, resulting in tumor recurrence and eventually metastasis. CSCs are situated in a specialized microenvironment termed the niche, mainly composed of fibroblasts and endothelial, mesenchymal and immune cells, which also play pivotal roles in drug resistance. These neighboring cells promote the molecular signaling pathways required for CSC maintenance and survival and also trigger endogenous drug resistance in CSCs. In addition, tumor niche components such as the extracellular matrix also physically shelter CSCs from therapeutic agents. Interestingly, CSCs contribute directly to the niche in a bilateral feedback loop manner. Here, we review the recent advances in the study of CSCs, the niche and especially their collective contribution to resistance, since increasingly studies suggest that this interaction should be considered as a target for therapeutic strategies.

AB - As the Asian country with the most aged population, Japan, has been modifying its social welfare system. In 2000, the Japanese social care vision turned towards meeting the elderly's care needs in their own homes with proper formal care services. This study aims to understand the quantitative properties of the macro supply and demand structure for facilities for the elderly who require support or long-term care throughout Japan and present them as index values. Additionally, this study compares the targets for establishing long-term care facilities set by Japan's Ministry of Health, Labor and Welfare for 2025. In 2014, approximately 90% of all the people who were certified as requiring support and long-term care and those receiving preventive long-term care or long-term care services, were 75 years or older. The target increases in the number of established facilities by 2025 (for the 75-years-or-older population) were calculated to be 3.3% for nursing homes; 2.71% for long-term-care health facilities; 1.7% for group living facilities; and, 1.84% for community-based multi-care facilities. It was revealed that the establishment targets for 2025 also increase over current projections with the expected increase of the absolute number of users of group living facilities and community-based multi-care facilities. On the other hand, the establishment target for nursing homes remains almost the same as the current projection, whereas that for long-term-care health facilities decreases. These changes of facility ratios reveal that the Japanese social care system is shifting to realize 'Ageing in Place'. When considering households' tendencies, the target ratios for established facilities are expected to be applied to the other countries in Asia.

AB - Tocopherols, together with tocotrienols and plastochromanols belong to a group of lipophilic compounds also called tocochromanols or vitamin E. Considered to be one of the most powerful antioxidants, tocochromanols are solely synthesized by photosynthetic organisms including plants, algae, and cyanobacteria and, therefore, are an essential component in the human diet. Tocochromanols potent antioxidative properties are due to their ability to interact with polyunsaturated acyl groups and scavenge lipid peroxyl radicals and quench reactive oxygen species (ROS), thus protecting fatty acids from lipid peroxidation. In the plant model species Arabidopsis thaliana, the required genes for tocopherol biosynthesis and functional roles of tocopherols were elucidated in mutant and transgenic plants. Recent research efforts have led to new outcomes for the vitamin E biosynthetic and related pathways, and new possible alternatives for the biofortification of important crops have been suggested. Here, we review 30 years of research on tocopherols in model and crop species, with emphasis on the improvement of vitamin E content using transgenic approaches and classical breeding. We will discuss future prospects to further improve the nutritional value of our food. PMID- 29194406 TI - Whole Body and CNS Biodistribution of rhHNS in Cynomolgus Monkeys after Intrathecal Lumbar Administration: Treatment Implications for Patients with MPS IIIA. AB - Mucopolysaccharidosis III type A (MPS IIIA; Sanfilippo syndrome), a genetic lysosomal disorder causing a deficiency of heparan N-sulfatase (HNS), leads to progressive cognitive decline from an early age. An effective enzyme replacement therapy (ERT) for MPS IIIA requires central nervous system (CNS) biodistribution. Recombinant human heparan N-sulfatase (rhHNS), an investigatory ERT for MPS IIIA, has been formulated for intrathecal (IT) administration since intravenous (IV) administration cannot cross the blood brain barrier (BBB) in sufficient amounts to have a therapeutic effect. In this study, systemic and CNS distribution of rhHNS in cynomolgus monkeys following IV and IT administration was evaluated by quantitation of rhHNS in serum, cerebral spinal fluid (CSF) and various tissues, and positron emission tomography (PET) imaging of live animals. Following IV administration, rhHNS levels were low to non-detectable in the CSF, and systemic clearance was rapid (<=2 h). With IT administration, rhHNS was observable in CNS tissues in <=1 h, with varying Tmax (1-24 h). Appreciable systemic distribution was observed up to 7 days. This provides evidence that in this animal model, intrathecal administration of rhHNS delivers the replacement enzyme to therapeutically relevant tissues for the treatment of Sanfilippo Syndrome type A. Penetration into grey matter and cortex was 3-4 times greater than concentrations in white matter and deeper parenchymal regions, suggesting some limitations of this ERT strategy. PMID- 29194407 TI - Adaptive Residual Interpolation for Color and Multispectral Image Demosaicking. AB - Color image demosaicking for the Bayer color filter array is an essential image processing operation for acquiring high-quality color images. Recently, residual interpolation (RI)-based algorithms have demonstrated superior demosaicking performance over conventional color difference interpolation-based algorithms. In this paper, we propose adaptive residual interpolation (ARI) that improves existing RI-based algorithms by adaptively combining two RI-based algorithms and selecting a suitable iteration number at each pixel. These are performed based on a unified criterion that evaluates the validity of an RI-based algorithm. Experimental comparisons using standard color image datasets demonstrate that ARI can improve existing RI-based algorithms by more than 0.6 dB in the color peak signal-to-noise ratio and can outperform state-of-the-art algorithms based on training images. We further extend ARI for a multispectral filter array, in which more than three spectral bands are arrayed, and demonstrate that ARI can achieve state-of-the-art performance also for the task of multispectral image demosaicking. PMID- 29194408 TI - Exposure to Night-Time Traffic Noise, Melatonin-Regulating Gene Variants and Change in Glycemia in Adults. AB - Traffic noise has been linked to diabetes, with limited understanding of its mechanisms. We hypothesize that night-time road traffic noise (RTN) may impair glucose homeostasis through circadian rhythm disturbances. We prospectively investigated the relationship between residential night-time RTN and subsequent eight-year change in glycosylated hemoglobin (DeltaHbA1c) in 3350 participants of the Swiss Cohort Study on Air Pollution and Lung and Heart Diseases in Adults (SAPALDIA), adjusting for diabetes risk factors and air pollution levels. Annual average RTN (Lnight) was assigned to participants in 2001 using validated Swiss noise models. HbA1c was measured in 2002 and 2011 using liquid chromatography. We applied mixed linear models to explore RTN-DeltaHbA1c association and its modification by a genetic risk score of six common circadian-related MTNR1B variants (MGRS). A 10 dB difference in RTN was associated with a 0.02% (0.003 0.04%) increase in mean DeltaHbA1c in 2142 non-movers. RTN-DeltaHbA1c association was modified by MGRS among diabetic participants (Pinteraction = 0.001). A similar trend in non-diabetic participants was non-significant. Among the single variants, we observed strongest interactions with rs10830963, an acknowledged diabetes risk variant also implicated in melatonin profile dysregulation. Night time RTN may impair glycemic control, especially in diabetic individuals, through circadian rhythm disturbances. Experimental sleep studies are needed to test whether noise control may help individuals to attain optimal glycemic levels. PMID- 29194411 TI - Incentive Policy Options for Product Remanufacturing: Subsidizing Donations or Resales? AB - Remanufactured products offer better environmental benefits, and governments encourage manufacturers to remanufacture through various subsidy policies. This practice has shown that, in addition to product sales, remanufactured product can also achieve its value through social donation. Based on the remanufactured product value realization approaches, governments provide two kinds of incentive policies, which are remanufactured product sales subsidies and remanufactured product donation subsidies. This paper constructs a two-stage Stackelberg game model including a government and a manufacturer under two different policies, which can be solved by backward induction. By comparing the optimal decision of the two policies, our results show that, compared with the remanufacturing sales subsidy, donation subsidy weakens the cannibalization of remanufactured products for new products and increases the quantity of new products. It reduces the sales quantity of remanufactured products, but increases their total quantity. Under certain conditions of low subsidy, the manufacturer adopting sales subsidy provides better economic and environmental benefits. Under certain conditions of high subsidy, the manufacturer adopting donation subsidy offers better economic and environmental benefits. When untreated product environmental impact is large enough, donation subsidy policy has a better social welfare. Otherwise, the choice of social welfare of these two different policies depends on the social impact of remanufactured product donated. PMID- 29194409 TI - Auxin Information Processing; Partners and Interactions beyond the Usual Suspects. AB - Auxin plays a major role in a variety of processes involved in plant developmental patterning and its adaptation to environmental conditions. Therefore, an important question is how specificity in auxin signalling is achieved, that is, how a single signalling molecule can carry so many different types of information. In recent years, many studies on auxin specificity have been published, unravelling increasingly more details on differential auxin sensitivity, expression domains and downstream partners of the auxin receptors (transport inhibitor response 1 (TIR1) and other auxin signaling F-box proteins (AFB)), transcriptional repressors that are degraded in response to auxin (AUX/IAA) and downstream auxin response factors (ARF) that together constitute the plant's major auxin response pathways. These data are critical to explain how, in the same cells, different auxin levels may trigger different responses, as well as how in different spatial or temporal contexts similar auxin signals converge to different responses. However, these insights do not yet answer more complex questions regarding auxin specificity. As an example, they leave open the question of how similar sized auxin changes at similar locations result in different responses depending on the duration and spatial extent of the fluctuation in auxin levels. Similarly, it leaves unanswered how, in the case of certain tropisms, small differences in signal strength at both sides of a plant organ are converted into an instructive auxin asymmetry that enables a robust tropic response. Finally, it does not explain how, in certain cases, substantially different auxin levels become translated into similar cellular responses, while in other cases similar auxin levels, even when combined with similar auxin response machinery, may trigger different responses. In this review, we illustrate how considering the regulatory networks and contexts in which auxin signalling takes place helps answer these types of fundamental questions.

AB - Efficient synthesis of phenanthridin-6(5H)-one derivatives 12a-n in a four component reaction of aldehyde hydrazone, aromatic aldehydes and malononitrile in Q-Tubes is reported. The results showed that the methodology has the advantage of being a one-pot synthesis of tricyclic systems in good yields. Potential routes leading to formation of compounds 12 are discussed. The structures of the synthesized compounds could be unequivocally established via X-ray crystal structure determination and spectroscopic methods. PMID- 29194413 TI - An Interface for Biomedical Big Data Processing on the Tianhe-2 Supercomputer. AB - Big data, cloud computing, and high-performance computing (HPC) are at the verge of convergence. Cloud computing is already playing an active part in big data processing with the help of big data frameworks like Hadoop and Spark. The recent upsurge of high-performance computing in China provides extra possibilities and capacity to address the challenges associated with big data. In this paper, we propose Orion-a big data interface on the Tianhe-2 supercomputer-to enable big data applications to run on Tianhe-2 via a single command or a shell script. Orion supports multiple users, and each user can launch multiple tasks. It minimizes the effort needed to initiate big data applications on the Tianhe-2 supercomputer via automated configuration. Orion follows the "allocate-when needed" paradigm, and it avoids the idle occupation of computational resources. We tested the utility and performance of Orion using a big genomic dataset and achieved a satisfactory performance on Tianhe-2 with very few modifications to existing applications that were implemented in Hadoop/Spark. In summary, Orion provides a practical and economical interface for big data processing on Tianhe 2.

AB - A previously unreported dihydrochromone dimer, paecilin E (1), was isolated, together with eleven known compounds: beta-sitostenone, ergosta-4,6,8 (14), 22 tetraen-3-one, cyathisterone, byssochlamic acid, dehydromevalonic acid lactone, chevalone B, aszonalenin, dankasterone A (2), helvolic acid, secalonic acid A and fellutanine A, from the culture filtrate extract of the marine sponge-associated fungus Neosartorya fennelliae KUFA 0811. Nine previously reported metabolites, including a chromanol derivative (3), (3beta, 5alpha, 22E), 3,5-dihydroxyergosta 7,22-dien-6-one (4), byssochlamic acid, hopan-3beta,22-diol, chevalone C, sartorypyrone B, helvolic acid, lumichrome and the alkaloid harmane were isolated from the culture of the marine-sponge associated fungus Neosartorya tsunodae KUFC 9213. Paecilin E (1), dankasterone A (2), a chromanol derivative (3), (3beta, 5alpha, 22E)-3,5-dihydroxyergosta-7,22-dien-6-one (4), hopan-3beta,22-diol (5), lumichrome (6), and harmane (7) were tested for their antibacterial activity against Gram-positive and Gram-negative reference and multidrug-resistant strains isolated from the environment. While paecilin E (1) was active against S. aureus ATCC 29213 and E. faecalis ATCC 29212, dankastetrone A (2) was only effective against E. faecalis ATCC 29212 and the multidrug-resistant VRE E. faecalis A5/102. Both compounds neither inhibit biofilm mass production in any of the strains at the concentrations tested nor exhibit synergistic association with antibiotics. PMID- 29194414 TI - Marked Object Recognition Multitouch Screen Printed Touchpad for Interactive Applications. AB - The market for interactive platforms is rapidly growing, and touchscreens have been incorporated in an increasing number of devices. Thus, the area of smart objects and devices is strongly increasing by adding interactive touch and multimedia content, leading to new uses and capabilities. In this work, a flexible screen printed sensor matrix is fabricated based on silver ink in a polyethylene terephthalate (PET) substrate. Diamond shaped capacitive electrodes coupled with conventional capacitive reading electronics enables fabrication of a highly functional capacitive touchpad, and also allows for the identification of marked objects. For the latter, the capacitive signatures are identified by intersecting points and distances between them. Thus, this work demonstrates the applicability of a low cost method using royalty-free geometries and technologies for the development of flexible multitouch touchpads for the implementation of interactive and object recognition applications. PMID- 29194415 TI - Efficient Background Segmentation and Seed Point Generation for a Single-Shot Stereo System. AB - Single-shot stereo 3D shape measurement is becoming more popular due to its advantages of noise robustness and short acquisition period. One of the key problems is stereo matching, which is related to the efficiency of background segmentation and seed point generation, etc. In this paper, a more efficient and automated matching algorithm based on digital image correlation (DIC) is proposed. The standard deviation of image gradients and an adaptive threshold are employed to segment the background. Scale-invariant feature transform (SIFT) based feature matching and two-dimensional triangulation are combined to estimate accurate initial parameters for seed point generation. The efficiency of background segmentation and seed point generation, as well as the measuring precision, are evaluated by experimental simulation and real tests. Experimental results show that the average segmentation time for an image with a resolution of 1280 * 960 pixels is 240 milliseconds. The efficiency of seed point generation is verified to be high with different convergence criteria. PMID- 29194416 TI - Melatonin Pharmacokinetics Following Oral Administration in Preterm Neonates. AB - Melatonin possesses potential efficacy in perinatal brain injuries, and has been proposed as adjunctive pharmacological therapy in combination with hypothermia in the clinical setting. However, the pharmacokinetics of melatonin in preterm and term newborns is still unknown. The aim of this study was to analyze the pharmacokinetics of melatonin after intragastric administration in preterm infants. Preterm newborns were enrolled 24-72 h after birth, and randomly assigned to three groups receiving a single bolus of 0.5 mg.kg-1 melatonin, or 3 boluses of 1 or 5 mg.kg-1 of melatonin at 24-h intervals. Blood samples were collected before and at selective times after melatonin administration. The half life of melatonin in plasma ranged from 7.98 to 10.94 h, and the area under the curve (AUC) from 10.48 to 118.17 ug.mL-1.h-1. Our results indicate a different pharmacokinetic profile in premature newborns, compared to adults and experimental animals. The high peak plasma concentrations and the long half-life indicate that in the neonatal clinical setting, it is possible to obtain and maintain high serum concentrations using a single administration of melatonin repeated every 12/24 h.

AB - The ability to synthesize upconversion nanocrystals (UCNCs) with tailored upconversion luminescence and controlled size is of great importance for biophotonic applications. However, until now, limited success has been met to prepare bright, ultrasmall, and monodispersed beta-NaYF4:Yb3+/Er3+ UCNCs. In this work, we report on a synthetic method to produce monodisperse hexagonal NaYF4:Yb3+/Er3+ nanocrystals of ultrasmall size (5.4 nm) through a precise control of the reaction temperature and the ratio of Na+/Ln3+/F-. We determined the optimum activator concentration of Er3+ to be 6.5 mol % for these UCNCs, yielding about a 5-fold higher upconversion luminescence (UCL) intensity than the commonly used formula of NaYF4:30% Yb3+/2% Er3+. Moreover, a thin epitaxial shell (thickness, 1.9 nm) of NaLnF4 (Ln = Y, Gd, Lu) was grown onto these ultrasmall NaYF4:Yb3+/Er3+ NCs, enhancing its UCL by about 85-, 70- and 50-fold, respectively. The achieved sub-10-nm core and core-shell hexagonal NaYF4:Yb3+/Er3+ UCNCs with enhanced UCL have strong potential applications in bioapplications such as bioimaging and biosensing. PMID- 29194417 TI - Matrix-Assisted Laser Desorption/Ionisation Mass Spectrometry Imaging in the Study of Gastric Cancer: A Mini Review. AB - Gastric cancer (GC) is one of the leading causes of cancer-related deaths worldwide and the disease outcome commonly depends upon the tumour stage at the time of diagnosis. However, this cancer can often be asymptomatic during the early stages and remain undetected until the later stages of tumour development, having a significant impact on patient prognosis. However, our comprehension of the mechanisms underlying the development of gastric malignancies is still lacking. For these reasons, the search for new diagnostic and prognostic markers for gastric cancer is an ongoing pursuit. Modern mass spectrometry imaging (MSI) techniques, in particular matrix-assisted laser desorption/ionisation (MALDI), have emerged as a plausible tool in clinical pathology as a whole. More specifically, MALDI-MSI is being increasingly employed in the study of gastric cancer and has already elucidated some important disease checkpoints that may help us to better understand the molecular mechanisms underpinning this aggressive cancer. Here we report the state of the art of MALDI-MSI approaches, ranging from sample preparation to statistical analysis, and provide a complete review of the key findings that have been reported in the literature thus far. PMID- 29194420 TI - Early Detection and Intervention of ASD: A European Overview. AB - Over the last several years there has been an increasing focus on early detection of Autism Spectrum Disorder (ASD), not only from the scientific field but also from professional associations and public health systems all across Europe. Not surprisingly, in order to offer better services and quality of life for both children with ASD and their families, different screening procedures and tools have been developed for early assessment and intervention. However, current evidence is needed for healthcare providers and policy makers to be able to implement specific measures and increase autism awareness in European communities. The general aim of this review is to address the latest and most relevant issues related to early detection and treatments. The specific objectives are (1) analyse the impact, describing advantages and drawbacks, of screening procedures based on standardized tests, surveillance programmes, or other observational measures; and (2) provide a European framework of early intervention programmes and practices and what has been learnt from implementing them in public or private settings. This analysis is then discussed and best practices are suggested to help professionals, health systems and policy makers to improve their local procedures or to develop new proposals for early detection and intervention programmes. PMID- 29194421 TI - Comparative Studies on Ultraviolet-Light-Derived Photoresponse Properties of ZnO, AZO, and GZO Transparent Semiconductor Thin Films. AB - ZnO, Al-doped ZnO (AZO), and Ga-doped ZnO (GZO) semiconductor thin films were deposited on glass substrates via a sol-gel spin-coating process for application in a photoconductive ultraviolet (UV) detector. The doping concentrations of Al and Ga were 1.0 at % in the precursor solutions. In this study, the microstructural features and the optical and electrical properties of sol-gel derived ZnO, AZO, and GZO thin films were compared, and the performance of ZnO based UV photodetectors under ultraviolet A (UVA) light were measured. Experimental results confirmed the synthesis of single-phase nanocrystalline ZnO based thin films and the successful substitution of Al and Ga into Zn sites in ZnO crystals. The results also demonstrated that the optical transmittance and electrical properties of ZnO thin films could be improved by Al and Ga doping. UV photodetectors based on ZnO-based thin films, having a metal-semiconductor-metal (MSM) configuration, were fabricated with Al inter-digitated electrodes. All photodetectors showed an ohmic nature between semiconductor and electrode contacts and exhibited a sharp increase in photocurrent under illumination with UVA light. We found that the MSM UV photodetector based on the GZO semiconductor thin film exhibited the best UV response (IUVA/Idark) of 73.3 and the highest photocurrent responsivity of 46.2 A/W under UVA light (power density ~0.825 mW/cm2) at 5 V bias. PMID- 29194419 TI - The Interplay between Natural Killer Cells and Human Herpesvirus-6. AB - Human Herpesvirus 6 (HHV-6) is a set of two closely related herpes viruses known as HHV-6A and HHV-6B. Both are lymphotropic viruses that establish latency in the host. The ability to evade the immune responses of effector cells is likely a major factor contributing to the development of a persistent HHV-6A/B (collectively termed HHV-6) infection. Natural killer (NK) cells are lymphocytes that, along with neutrophils and monocytes/macrophages, participate in the critical innate immune response during viral infections, but can also mediate the antigen-specific memory responses generally associated with adaptive immunity. NK cells compose the first barrier that viruses must break through to continue replication and dissemination, and a weak NK cell response may predispose an individual to chronic viral infections. Both HHV-6A and HHV-6B can interfere with NK cell-mediated anti-viral responses but the mechanisms by which each of these viruses affect NK cell activity differs. In this review, we will explore the nuanced relationships between the two viruses and NK cells, discussing, in addition, relevant disease associations. PMID- 29194422 TI - Food and Nutrient Intake and Nutrient Sources in 1-Year-Old Infants in Finland: A Cross-Sectional Analysis. AB - The infant diet has short- and long-term health consequences. Updated data regarding the dietary intake of Finnish infants are lacking. The objectives of this study were to describe infant food and nutrient intake and to identify food sources of the nutrients. Altogether, 739 healthy infants were studied. Dietary intake and breastfeeding frequency were assessed with a three-day food record at 1 year of age. Dietary intake was calculated separately for non-breastfed and breastfed infants. One-third (36%) of the infants were partially breastfed and 95% consumed mass-produced baby foods. The infants' diet consisted mainly of infant formula, dairy milk, porridges, fruit and berry foods, and meat dishes. The mean vegetable, fruit and berry consumption was 199 g/day. Most nutrient intakes were adequate except for fat, linoleic acid, vitamin D and iron from food. Mean sucrose intake, as a percentage of total energy intake (E%), was 5-6 E%. High protein intake (>20 E%) was observed in 19% of non-breastfed infants. Overall, the infants' diet was favorable since vegetable and fruit consumption was reasonably high and nutrient intake was mostly adequate. However, the fat intake was lower, and protein intake higher than recommended. Increasing the consumption of vegetable oils and reducing the intake of red meat and dairy milk may further improve the diet of 1-year-olds.

AB - Exopolysaccharide from Crypthecodinium cohnii (EPCP1-2) is a marine exopolysaccharide that evidences a variety of biological activities. We isolated a neutral polysaccharide from the fermentation liquid of Crypthecodinium cohnii (CP). In this study, a polysaccharide that is derived from Crypthecodinium cohnii were analyzed and its anti-inflammatory effect was evaluated on protein expression of toll-like receptor 4 and nuclear factor kappaB pathways in macrophages. The structural characteristics of EPCP1-2 were characterized by GC (gas chromatography) and GC-MS (gas Chromatography-Mass Spectrometer) analyses. The molecular weight was about 82.5 kDa. The main chain of EPCP1-2 consisted of (1->6)-linked mannopyranosyl, (1->6)-linked glucopyranosyl, branched-chain consisted of (1->3,6)-linked galactopyranosyl and terminal consisted of t-l Rhapyranosyl. The in vitro anti-inflammatory activity was representated through assay of proliferation rate, pro-inflammatory factor (NO) and expressions of proteins on RAW 264.7, the macrophage cell line. The results revealed that EPCP1 2 exhibited significant anti-inflammatory activity by regulating the expression of toll-like receptor 4, mitogen-activated protein kinases, and Nuclear Factor kappaB protein. PMID- 29194425 TI - Contribution of Discretionary Foods and Drinks to Australian Children's Intake of Energy, Saturated Fat, Added Sugars and Salt. AB - Interventions are required to reduce children's consumption of discretionary foods and drinks. To intervene we need to identify appropriate discretionary choice targets. This study aimed to determine the main discretionary choice contributors to energy and key nutrient intakes in children aged 2-18 years. Secondary analyses were performed with population weighted, single 24 h dietary recall data from the 2011-2012 National Nutrition and Physical Activity Survey. Cakes, muffins, and slices; sweet biscuits; potato crisps and similar snacks; and, processed meats and sugar-sweetened drinks were relatively commonly consumed and were within the top three to five contributors to per capita energy, saturated fat, sodium, and/or added sugars. Per consumer intake identified cereal based takeaway foods; cakes, muffins and slices; meat pies and other savoury pastries; and, processed meats as top contributors to energy, saturated fat, and sodium across most age groups. Subgroups of sugar-sweetened drinks and cakes, muffins and slices were consistently key contributors to added sugars intake. This study identified optimal targets for interventions to reduce discretionary choices intake, likely to have the biggest impact on moderating energy intake while also reducing intakes of saturated fat, sodium and/or added sugars. PMID- 29194424 TI - Functional Foods and Lifestyle Approaches for Diabetes Prevention and Management. AB - Functional foods contain biologically active ingredients associated with physiological health benefits for preventing and managing chronic diseases, such as type 2 diabetes mellitus (T2DM). A regular consumption of functional foods may be associated with enhanced anti-oxidant, anti-inflammatory, insulin sensitivity, and anti-cholesterol functions, which are considered integral to prevent and manage T2DM. Components of the Mediterranean diet (MD)-such as fruits, vegetables, oily fish, olive oil, and tree nuts-serve as a model for functional foods based on their natural contents of nutraceuticals, including polyphenols, terpenoids, flavonoids, alkaloids, sterols, pigments, and unsaturated fatty acids. Polyphenols within MD and polyphenol-rich herbs-such as coffee, green tea, black tea, and yerba mate-have shown clinically-meaningful benefits on metabolic and microvascular activities, cholesterol and fasting glucose lowering, and anti inflammation and anti-oxidation in high-risk and T2DM patients. However, combining exercise with functional food consumption can trigger and augment several metabolic and cardiovascular protective benefits, but it is under investigated in people with T2DM and bariatric surgery patients. Detecting functional food benefits can now rely on an "omics" biological profiling of individuals' molecular, genetics, transcriptomics, proteomics, and metabolomics, but is under-investigated in multi-component interventions. A personalized approach for preventing and managing T2DM should consider biological and behavioral models, and embed nutrition education as part of lifestyle diabetes prevention studies.

In this invited review, the main parameters which are used to characterize the performance of WOLEDs are introduced. Subsequently, the state-of-the-art strategies to achieve high-performance WOLEDs in recent years are summarized. Specifically, the manipulation of charges and excitons distribution in the four types of WOLEDs (fluorescent WOLEDs, phosphorescent WOLEDs, thermally activated delayed fluorescent WOLEDs, and fluorescent/phosphorescent hybrid WOLEDs) are comprehensively highlighted. Moreover, doping-free WOLEDs are described. Finally, issues and ways to further enhance the performance of WOLEDs are briefly clarified. PMID- 29194428 TI - Correction: Nabeshima, Y., et al.

PMID- 29194429 TI - Hazard Ranking Method for Populations Exposed to Arsenic in Private Water Supplies: Relation to Bedrock Geology. AB - Approximately one million people in the UK are served by private water supplies (PWS) where main municipal water supply system connection is not practical or where PWS is the preferred option. Chronic exposure to contaminants in PWS may have adverse effects on health. South West England is an area with elevated arsenic concentrations in groundwater and over 9000 domestic dwellings here are supplied by PWS. There remains uncertainty as to the extent of the population exposed to arsenic (As), and the factors predicting such exposure. We describe a hazard assessment model based on simplified geology with the potential to predict exposure to As in PWS. Households with a recorded PWS in Cornwall were recruited to take part in a water sampling programme from 2011 to 2013. Bedrock geologies were aggregated and classified into nine Simplified Bedrock Geological Categories (SBGC), plus a cross-cutting "mineralized" area. PWS were sampled by random selection within SBGCs and some 508 households volunteered for the study. Transformations of the data were explored to estimate the distribution of As concentrations for PWS by SBGC. Using the distribution per SBGC, we predict the proportion of dwellings that would be affected by high concentrations and rank the geologies according to hazard. Within most SBGCs, As concentrations were found to have log-normal distributions. Across these areas, the proportion of dwellings predicted to have drinking water over the prescribed concentration value (PCV) for As ranged from 0% to 20%. From these results, a pilot predictive model was developed calculating the proportion of PWS above the PCV for As and hazard ranking supports local decision making and prioritization. With further development and testing, this can help local authorities predict the number of dwellings that might fail the PCV for As, based on bedrock geology. The model presented here for Cornwall could be applied in areas with similar geologies. Application of the method requires independent validation and further groundwater derived PWS sampling on other geological formations.

AB - Cellular receptor-mediated signaling pathways play critical roles during the initial immune response to Human Cytomegalovirus (HCMV) infection. However, the involvement of type-I transmembrane glycoprotein CD147/EMMPRIN (extracellular matrix metalloproteinase inducer) in the antiviral response to HCMV infection is still unknown. Here, we demonstrated the specific knockdown of CD147 significantly decreased HCMV-induced activation of NF-kappaB and Interferon-beta (IFN-beta), which contribute to the cellular antiviral responses. Next, we confirmed that HCMV-encoded miR-US25-1-5p could target the 3' UTR (Untranslated Region) of CD147 mRNA, and thus facilitate HCMV lytic propagation at a low multiplicity of infection (MOI). The expression and secretion of Cyclophilin A (sCyPA), as a ligand for CD147 and a proinflammatory cytokine, were up-regulated in response to HCMV stimuli. Finally, we confirmed that CD147 mediated HCMV triggered antiviral signaling via the sCyPA-CD147-ERK (extracellular regulated protein kinases)/NF-kappaB axis signaling pathway. These findings reveal an important HCMV mechanism for evading antiviral innate immunity through its encoded microRNA by targeting transmembrane glycoprotein CD147, and a potential cause of HCMV inflammatory disorders due to the secretion of proinflammatory cytokine CyPA.

AB - BACKGROUND Knee osteoarthritis (KOA) is a common disease that can change the load on lower limbs during walking. Plantar loads in patients with KOA may provide a basis for clinical decisions regarding footwear and foot orthoses. This study aimed to compare plantar loads in females with and without KOA during gait. MATERIAL AND METHODS Plantar pressure during walking was recorded in 23 females with KOA and 23 females without KOA. Maximum force (MF), contact area (CA), and peak pressure (PP) were measured at 7 different regions underneath the foot, named heel (M1), midfoot (M2), first metatarsophalangeal joint (MPJ) (M3), second MPJ (M4), third to fifth MPJ (M5), hallux (M6), and lesser toes (M7). RESULTS PPs for M2 and (M3) in females with KOA were higher than those in females without KOA. High PPs were also found in females with KOA for M2, M3, and M4. CONCLUSIONS Increased plantar loading in females with KOA may lead to foot pronation and gait changes during walking. Plantar loading may be offered to patients with KOA when considering footwear and foot orthoses. PMID- 29194427 TI - Control of Endogenous Auxin Levels in Plant Root Development. AB - In this review, we summarize the different biosynthesis-related pathways that contribute to the regulation of endogenous auxin in plants. We demonstrate that all known genes involved in auxin biosynthesis also have a role in root formation, from the initiation of a root meristem during embryogenesis to the generation of a functional root system with a primary root, secondary lateral root branches and adventitious roots. Furthermore, the versatile adaptation of root development in response to environmental challenges is mediated by both local and distant control of auxin biosynthesis. In conclusion, auxin homeostasis mediated by spatial and temporal regulation of auxin biosynthesis plays a central role in determining root architecture. PMID- 29194432 TI - Do cannabinoids constitute a therapeutic alternative for anorexia nervosa? AB - INTRODUCTION: Cannabinoids have been postulated as an alternative for anorexia nervosa. However, their actual clinical efficacy and safety are still discussed. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified four systematic reviews including two primary studies, both corresponding to randomized trials. We concluded cannabinoids might not increase weight or improve symptoms in anorexia nervosa, and are probably associated to frequent adverse effects. PMID- 29194433 TI - Health inequalities and the impact on the prevalence of cardiovascular risk factors and chronic complications in Argentina: a study on national risk factors surveys. AB - BACKGROUND: In Argentina, there is evidence of health inequalities, measured both at the general level and also using income as a parameter of social status. However, few studies address the issue of health equality in chronic diseases such as cardiovascular risk factors. OBJECTIVE: To describe health inequalities, using cardiovascular risk factors as a tracer for chronic diseases in different areas of the country and over time. In addition, we aim to identify differences in the quality of care provided to people with cardiovascular risk factors, between 2005 and 2009. METHODS: This is an observational study, which used descriptive and quantitative methods. Data from the National Risk Factors Survey from 2005 and 2009 in the cohorts who have chronic diseases (hypertension, diabetes, dyslipidemia and overweight/obesity) were analyzed to assess associations between health status and several demographic, epidemiological and socioeconomic variables. Additionally, clinical and metabolic characteristics of people with diabetes and other cardiovascular risks factors were analyzed in 2005 and 2009 using the database Quality of Diabetes Care (QUALIDIAB). RESULTS: Cardiovascular risk factors are more frequent in people with lower socioeconomic status, regardless of the indicator. The inequalities detected showed the worst indicators in strata with lower education and income, with the same results both nationwide and separated by region. This inequalities were more pronounced in 2009, and their magnitude changed by region and cardiovascular risk factor. From 2005 to 2009, body mass index, blood glucose and HbA1c value increased. In contrast, both systolic blood pressure and triglycerides decreased, with no significant changes in total cholesterol and diastolic blood pressure. CONCLUSION: Cardiovascular risk factors present inequalities attributed to social status manifesting at both national and regional levels. PMID- 29194434 TI - Metabomatching: Using genetic association to identify metabolites in proton NMR spectroscopy. AB - A metabolome-wide genome-wide association study (mGWAS) aims to discover the effects of genetic variants on metabolome phenotypes. Most mGWASes use as phenotypes concentrations of limited sets of metabolites that can be identified and quantified from spectral information. In contrast, in an untargeted mGWAS both identification and quantification are forgone and, instead, all measured metabolome features are tested for association with genetic variants. While the untargeted approach does not discard data that may have eluded identification, the interpretation of associated features remains a challenge. To address this issue, we developed metabomatching to identify the metabolites underlying significant associations observed in untargeted mGWASes on proton NMR metabolome data. Metabomatching capitalizes on genetic spiking, the concept that because metabolome features associated with a genetic variant tend to correspond to the peaks of the NMR spectrum of the underlying metabolite, genetic association can allow for identification. Applied to the untargeted mGWASes in the SHIP and CoLaus cohorts and using 180 reference NMR spectra of the urine metabolome database, metabomatching successfully identified the underlying metabolite in 14 of 19, and 8 of 9 associations, respectively. The accuracy and efficiency of our method make it a strong contender for facilitating or complementing metabolomics analyses in large cohorts, where the availability of genetic, or other data, enables our approach, but targeted quantification is limited. PMID- 29194435 TI - Adiposity QTL Adip20 decomposes into at least four loci when dissected using congenic strains. AB - An average mouse in midlife weighs between 25 and 30 g, with about a gram of tissue in the largest adipose depot (gonadal), and the weight of this depot differs between inbred strains. Specifically, C57BL/6ByJ mice have heavier gonadal depots on average than do 129P3/J mice. To understand the genetic contributions to this trait, we mapped several quantitative trait loci (QTLs) for gonadal depot weight in an F2 intercross population. Our goal here was to fine map one of these QTLs, Adip20 (formerly Adip5), on mouse chromosome 9. To that end, we analyzed the weight of the gonadal adipose depot from newly created congenic strains. Results from the sequential comparison method indicated at least four rather than one QTL; two of the QTLs were less than 0.5 Mb apart, with opposing directions of allelic effect. Different types of evidence (missense and regulatory genetic variation, human adiposity/body mass index orthologues, and differential gene expression) implicated numerous candidate genes from the four QTL regions. These results highlight the value of mouse congenic strains and the value of this sequential method to dissect challenging genetic architecture. PMID- 29194436 TI - Characterisation of the pathogenic effects of the in vivo expression of an ALS linked mutation in D-amino acid oxidase: Phenotype and loss of spinal cord motor neurons. AB - Amyotrophic lateral sclerosis (ALS) is the most common adult-onset neuromuscular disorder characterised by selective loss of motor neurons leading to fatal paralysis. Current therapeutic approaches are limited in their effectiveness. Substantial advances in understanding ALS disease mechanisms has come from the identification of pathogenic mutations in dominantly inherited familial ALS (FALS). We previously reported a coding mutation in D-amino acid oxidase (DAOR199W) associated with FALS. DAO metabolises D-serine, an essential co agonist at the N-Methyl-D-aspartic acid glutamate receptor subtype (NMDAR). Using primary motor neuron cultures or motor neuron cell lines we demonstrated that expression of DAOR199W, promoted the formation of ubiquitinated protein aggregates, activated autophagy and increased apoptosis. The aim of this study was to characterise the effects of DAOR199W in vivo, using transgenic mice overexpressing DAOR199W. Marked abnormal motor features, e.g. kyphosis, were evident in mice expressing DAOR199W, which were associated with a significant loss (19%) of lumbar spinal cord motor neurons, analysed at 14 months. When separated by gender, this effect was greater in females (26%; p< 0.0132). In addition, we crossed the DAOR199W transgenic mouse line with the SOD1G93A mouse model of ALS to determine whether the effects of SOD1G93A were potentiated in the double transgenic line (DAOR199W/SOD1G93A). Although overall survival was not affected, onset of neurological signs was significantly earlier in female double transgenic animals than their female SOD1G93A littermates (125 days vs 131 days, P = 0.0239). In summary, some significant in vivo effects of DAOR199W on motor neuron function (i.e. kyphosis and loss of motor neurons) were detected which were most marked in females and could contribute to the earlier onset of neurological signs in double transgenic females compared to SOD1G93A littermates, highlighting the importance of recognizing gender effects present in animal models of ALS. PMID- 29194437 TI - An introduction to the 'Psycho-Physiological-Stress-Test' (PPST)-A standardized instrument for evaluating stress reactions. AB - Using a standardized instrument to evaluate patients' stress reactions has become more important in daily clinical routines. Different signs or symptoms of stress are often unilaterally explored: the physiological, psychological or social aspects of stress disorders are each viewed on a single dimension. However, all dimensions afflict patients who have persistent health problems due to chronic stress. Therefore, it is important to use a multidimensional approach to acquire data. The 'Psycho-Physiological-Stress-Test' (PPST) was established to achieve a comprehensive understanding of stress and was further developed at the Charite Universitatsmedizin Berlin in collaboration with the Psychological Department of Freie Universitat Berlin. The PPST includes a series of varying stress phases, embedded in two periods of rest. Physiological and psychological parameters are simultaneously measured throughout the test session. Specifically, the PPST activates the sympathetic stress axis, which is measured by heart rate, blood pressure, respiration depth and rate, electro dermal activation and muscle tension (frontalis, masseter, trapezius). Psychological data are simultaneously collected, and include performance, motivation, emotion and behavior. After conducting this diagnostic test, it is possible to identify individual stress patterns that can be discussed with the individual patient to develop and recommend (outpatient) treatment strategies. This paper introduces the PPST as a standardized way to evaluate stress reactions by presenting the results from a sample of psychosomatic inpatients (n = 139) who were treated in Charite Universitatsmedizin Berlin, Germany. We observed that the varying testing conditions provoked adjusted changes in the different physiological parameters and psychological levels. PMID- 29194438 TI - A temporal comparison of sex-aggregation pheromone gland content and dynamics of release in three members of the Lutzomyia longipalpis (Diptera: Psychodidae) species complex. AB - BACKGROUND: Lutzomyia longipalpis is the South American vector of Leishmania infantum, the etiologic agent of visceral leishmaniasis (VL). Male L. longipalpis produce a sex-aggregation pheromone that is critical in mating, yet very little is known about its accumulation over time or factors involved in release. This laboratory study aimed to compare accumulation of pheromone over time and determine factors that might influence release in three members of the L. longipalpis species complex. METHODOLOGY/PRINCIPAL FINDINGS: We investigated male sex-aggregation pheromone gland content at different ages and the release rate of pheromone in the presence or absence of females under different light conditions by gas chromatography-mass spectrometry (GC-MS). Pheromone gland content was determined by extraction of whole males and pheromone release rate was determined by collection of headspace volatiles. Pheromone gland content appeared age related and pheromone began to accumulate between 6 to 12 h post eclosion and gradually increased until males were 7-9 days old. The greatest amount was detected in 9-day old Campo Grande males ((S)-9-methylgermacrene-B; X +/- SE: 203.5 +/- 57.4 ng/male) followed by Sobral 2S males (diterpene; 199.9 +/- 34.3) and Jacobina males ((1S,3S,7R)-3-methyl-alpha-himachalene; 128.8 +/- 30.3) at 7 days old. Pheromone release was not continuous over time. During a 4-hour period, the greatest quantities of pheromone were released during the first hour, when wing beating activity was most intense. It was then substantially diminished for the remainder of the time. During a 24 h period, 4-5 day old male sand flies released approximately 63 +/- 11% of the pheromone content of their glands, depending on the chemotype. The presence of females significantly increased pheromone release rate. The light regime under which the sand flies were held had little influence on pheromone release except on Sobral 2S chemotype. CONCLUSIONS/SIGNIFICANCE: Accumulation of pheromone appears to occur at different rates in the different chemotypes examined and results in differing amounts being present in glands over time. Release of accumulated pheromone is not passive, but depends on biotic (presence of females) and abiotic (light) circumstances. There are marked differences in content and release between the members of the complex suggesting important behavioural, biosynthetic and ecological differences between them. PMID- 29194439 TI - Genetic drift and selection in many-allele range expansions. AB - We experimentally and numerically investigate the evolutionary dynamics of four competing strains of E. coli with differing expansion velocities in radially expanding colonies. We compare experimental measurements of the average fraction, correlation functions between strains, and the relative rates of genetic domain wall annihilations and coalescences to simulations modeling the population as a one-dimensional ring of annihilating and coalescing random walkers with deterministic biases due to selection. The simulations reveal that the evolutionary dynamics can be collapsed onto master curves governed by three essential parameters: (1) an expansion length beyond which selection dominates over genetic drift; (2) a characteristic angular correlation describing the size of genetic domains; and (3) a dimensionless constant quantifying the interplay between a colony's curvature at the frontier and its selection length scale. We measure these parameters with a new technique that precisely measures small selective differences between spatially competing strains and show that our simulations accurately predict the dynamics without additional fitting. Our results suggest that the random walk model can act as a useful predictive tool for describing the evolutionary dynamics of range expansions composed of an arbitrary number of genotypes with different fitnesses. PMID- 29194440 TI - Attacking the mosquito on multiple fronts: Insights from the Vector Control Optimization Model (VCOM) for malaria elimination. AB - BACKGROUND: Despite great achievements by insecticide-treated nets (ITNs) and indoor residual spraying (IRS) in reducing malaria transmission, it is unlikely these tools will be sufficient to eliminate malaria transmission on their own in many settings today. Fortunately, field experiments indicate that there are many promising vector control interventions that can be used to complement ITNs and/or IRS by targeting a wide range of biological and environmental mosquito resources. The majority of these experiments were performed to test a single vector control intervention in isolation; however, there is growing evidence and consensus that effective vector control with the goal of malaria elimination will require a combination of interventions. METHOD AND FINDINGS: We have developed a model of mosquito population dynamic to describe the mosquito life and feeding cycles and to optimize the impact of vector control intervention combinations at suppressing mosquito populations. The model simulations were performed for the main three malaria vectors in sub-Saharan Africa, Anopheles gambiae s.s, An. arabiensis and An. funestus. We considered areas having low, moderate and high malaria transmission, corresponding to entomological inoculation rates of 10, 50 and 100 infective bites per person per year, respectively. In all settings, we considered baseline ITN coverage of 50% or 80% in addition to a range of other vector control tools to interrupt malaria transmission. The model was used to sweep through parameters space to select the best optimal intervention packages. Sample model simulations indicate that, starting with ITNs at a coverage of 50% (An. gambiae s.s. and An. funestus) or 80% (An. arabiensis) and adding interventions that do not require human participation (e.g. larviciding at 80% coverage, endectocide treated cattle at 50% coverage and attractive toxic sugar baits at 50% coverage) may be sufficient to suppress all the three species to an extent required to achieve local malaria elimination. CONCLUSION: The Vector Control Optimization Model (VCOM) is a computational tool to predict the impact of combined vector control interventions at the mosquito population level in a range of eco-epidemiological settings. The model predicts specific combinations of vector control tools to achieve local malaria elimination in a range of eco epidemiological settings and can assist researchers and program decision-makers on the design of experimental or operational research to test vector control interventions. A corresponding graphical user interface is available for national malaria control programs and other end users. PMID- 29194441 TI - Candida albicans FRE8 encodes a member of the NADPH oxidase family that produces a burst of ROS during fungal morphogenesis. AB - Until recently, NADPH oxidase (NOX) enzymes were thought to be a property of multicellularity, where the reactive oxygen species (ROS) produced by NOX acts in signaling processes or in attacking invading microbes through oxidative damage. We demonstrate here that the unicellular yeast and opportunistic fungal pathogen Candida albicans is capable of a ROS burst using a member of the NOX enzyme family, which we identify as Fre8. C. albicans can exist in either a unicellular yeast-like budding form or as filamentous multicellular hyphae or pseudohyphae, and the ROS burst of Fre8 begins as cells transition to the hyphal state. Fre8 is induced during hyphal morphogenesis and specifically produces ROS at the growing tip of the polarized cell. The superoxide dismutase Sod5 is co-induced with Fre8 and our findings are consistent with a model in which extracellular Sod5 acts as partner for Fre8, converting Fre8-derived superoxide to the diffusible H2O2 molecule. Mutants of fre8Delta/Delta exhibit a morphogenesis defect in vitro and are specifically impaired in development or maintenance of elongated hyphae, a defect that is rescued by exogenous sources of H2O2. A fre8Delta/Delta deficiency in hyphal development was similarly observed in vivo during C. albicans invasion of the kidney in a mouse model for disseminated candidiasis. Moreover C. albicans fre8Delta/Delta mutants showed defects in a rat catheter model for biofilms. Together these studies demonstrate that like multicellular organisms, C. albicans expresses NOX to produce ROS and this ROS helps drive fungal morphogenesis in the animal host. PMID- 29194442 TI - Sequence-dependent nucleosome sliding in rotation-coupled and uncoupled modes revealed by molecular simulations. AB - While nucleosome positioning on eukaryotic genome play important roles for genetic regulation, molecular mechanisms of nucleosome positioning and sliding along DNA are not well understood. Here we investigated thermally-activated spontaneous nucleosome sliding mechanisms developing and applying a coarse grained molecular simulation method that incorporates both long-range electrostatic and short-range hydrogen-bond interactions between histone octamer and DNA. The simulations revealed two distinct sliding modes depending on the nucleosomal DNA sequence. A uniform DNA sequence showed frequent sliding with one base pair step in a rotation-coupled manner, akin to screw-like motions. On the contrary, a strong positioning sequence, the so-called 601 sequence, exhibits rare, abrupt transitions of five and ten base pair steps without rotation. Moreover, we evaluated the importance of hydrogen bond interactions on the sliding mode, finding that strong and weak bonds favor respectively the rotation coupled and -uncoupled sliding movements.

AB - This is a formal commentary, responding to Matthew Curran Benigni, Kenneth Joseph, and Kathleen Carley's contribution, "Online extremism and the communities that sustain it: Detecting the ISIS supporting community on Twitter". This brief review reflects on the ethics of big data research methodologies, and how novel methods complicate long-standing principles of research ethics. Specifically, the concept of the "data subject" as a corollary, or replacement, of "human subject" is considered. PMID- 29194444 TI - Behavioral stress alters corticolimbic microglia in a sex- and brain region specific manner. AB - Women are more susceptible to numerous stress-linked psychological disorders (e.g., depression) characterized by dysfunction of corticolimbic brain regions critical for emotion regulation and cognitive function. Although sparsely investigated, a number of studies indicate sex differences in stress effects on neuronal structure, function, and behaviors associated with these regions. We recently demonstrated a basal sex difference in- and differential effects of stress on- microglial activation in medial prefrontal cortex (mPFC). The resident immune cells of the brain, microglia are implicated in synaptic and dendritic plasticity, and cognitive-behavioral function. Here, we examined the effects of acute (3h/day, 1 day) and chronic (3h/day, 10 days) restraint stress on microglial density and morphology, as well as immune factor expression in orbitofrontal cortex (OFC), basolateral amygdala (BLA), and dorsal hippocampus (DHC) in male and female rats. Microglia were visualized, classified based on their morphology, and stereologically counted. Microglia-associated transcripts (CD40, iNOS, Arg1, CX3CL1, CX3CR1, CD200, and CD200R) were assessed in brain punches from each region. Expression of genes linked with cellular stress, neuroimmune state, and neuron-microglia communication varied between unstressed male and female rats in a region-specific manner. In OFC, chronic stress upregulated a wider variety of immune factors in females than in males. Acute stress increased microglia-associated transcripts in BLA in males, whereas chronic stress altered immune factor expression in BLA more broadly in females. In DHC, chronic stress increased immune factor expression in males but not females. Moreover, acute and chronic stress differentially affected microglial morphological activation state in male and female rats across all brain regions investigated. In males, chronic stress altered microglial activation in a pattern consistent with microglial involvement in stress-induced dendritic remodeling across OFC, BLA, and DHC. Together, these data suggest the potential for microglia-mediated sex differences in stress effects on neural structure, function, and behavior. PMID- 29194446 TI - Online extremism and the communities that sustain it: Detecting the ISIS supporting community on Twitter. AB - The Islamic State of Iraq and ash-Sham (ISIS) continues to use social media as an essential element of its campaign to motivate support. On Twitter, ISIS' unique ability to leverage unaffiliated sympathizers that simply retweet propaganda has been identified as a primary mechanism in their success in motivating both recruitment and "lone wolf" attacks. The present work explores a large community of Twitter users whose activity supports ISIS propaganda diffusion in varying degrees. Within this ISIS supporting community, we observe a diverse range of actor types, including fighters, propagandists, recruiters, religious scholars, and unaffiliated sympathizers. The interaction between these users offers unique insight into the people and narratives critical to ISIS' sustainment. In their entirety, we refer to this diverse set of users as an online extremist community or OEC. We present Iterative Vertex Clustering and Classification (IVCC), a scalable analytic approach for OEC detection in annotated heterogeneous networks, and provide an illustrative case study of an online community of over 22,000 Twitter users whose online behavior directly advocates support for ISIS or contibutes to the group's propaganda dissemination through retweets. PMID- 29194445 TI - Safety and efficacy of an oxycodone vaccine: Addressing some of the unique considerations posed by opioid abuse. AB - Among vaccines aimed at treating substance use disorders, those targeting opioids present several unique medication development challenges. 1) Opioid overdose is a common complication of abuse, so it is desirable for an opioid vaccine to block the toxic as well as the addictive effects of opioids. 2) It is important that an opioid vaccine not interfere with the action of opioid antagonists used to reverse opioid overdose or treat addiction. 3) Some opioids are immunosuppressive and chronic ongoing opioid use could interfere with vaccine immunogenicity. 4) Although antibody-bound oxycodone is unable to enter the brain because of its size, it might still be able to activate peripheral opioid receptors. To assess vaccine impact on opioid toxicity, rats vaccinated with oxycodone conjugated to keyhole limpet hemocyanin subunit dimer (OXY-dKLH) adsorbed to alum or controls vaccinated with dKLH were compared with regard to oxycodone-induced hotplate analgesia and oxycodone-induced respiratory depression and bradycardia. Vaccination shifted the dose-response curves to the right, representing protection, for each of these endpoints. Naloxone was equally effective in both OXY-dKLH and control groups, providing complete and rapid reversal of respiratory depression. The administration of a long-acting naltrexone formulation during vaccination did not impair vaccine immunogenicity in mice. Similarly, serum anti oxycodone antibody titers were not altered by continuous morphine infusion during vaccination compared to opioid-naive controls. Competitive ELISA assay showed negligible or low affinity of immune antiserum for endogenous opioids or opioid antagonists. In vitro receptor binding assays showed that antibody-bound oxycodone does not activate mu opioid receptors. These data support further study of OXY-dKLH as a potential treatment for oxycodone abuse and suggest that vaccination might also reduce the severity of oxycodone overdose. PMID- 29194447 TI - Sevoflurane causes greater QTc interval prolongation in chronically hyperglycemic patients than in normoglycemic patients. AB - QTc interval prolongation is a serious diabetic complication and increases mortality rate. Hyperglycemia inhibits the rapid component of delayed rectifier potassium channel currents (Ikr) and prolongs the QTc interval on electrocardiograms. Sevoflurane also inhibits the Ikr and causes QTc interval prolongation. In fact, torsade de pointes occurred in a patient with poorly controlled diabetes mellitus during sevoflurane anesthesia. We enrolled 74 patients, including 37 normoglycemic patients (glycated hemoglobin [HbA1c]: <6.5%) (NG group) and 37 chronically hyperglycemic patients (HbA1c: >=6.5%) (HG group). Anesthesia was induced with 2 mg/kg propofol and 0.3 MUg/kg/min remifentanil, and maintained with 2% sevoflurane in 40% O2 and 0.2-0.3 MUg/kg/min remifentanil. The QT interval and Tp-e interval (from the peak to the end of the T wave) were measured before and at 5, 10, 30, 60, 90, and 120 min after the administration of sevoflurane and adjusted for the patient's heart rate (QTc and Tp-ec, respectively). P-values of <0.05 were considered statistically significant. The QTc and the Tp-ec intervals of the two groups did not differ significantly before the administration of sevoflurane. The QTc interval gradually increased with time in both groups and was significantly longer than the baseline value at 10 min after the administration of sevoflurane in both groups. The QTc interval of the HG group was significantly longer than that of the NG group at 90 min and 120 min after the administration of sevoflurane. The Tp-ec interval was not affected by sevoflurane in either group.We have demonstrated that sevoflurane significantly prolongs the QTc interval, and that the extent of the prolongation is significantly greater in chronically hyperglycemic patients than in normoglycemic patients. Although Tp-ec is not affected by sevoflurane, it should be noted that the simultaneous blockade of potassium channels would increase the risk of arrhythmias. PMID- 29194448 TI - Interleukin-1beta (IL-1beta)-induced Notch ligand Jagged1 suppresses mitogenic action of IL-1beta on human dystrophic myogenic cells. AB - Duchenne muscular dystrophy (DMD) is a severe X-linked recessive muscle disorder caused by mutations in the dystrophin gene. Nonetheless, secondary processes involving perturbation of muscle regeneration probably exacerbate disease progression, resulting in the fatal loss of muscle in DMD patients. A dysfunction of undifferentiated myogenic cells is the most likely cause for the reduction of regenerative capacity of muscle. To clarify molecular mechanisms in perturbation of the regenerative capacity of DMD muscle, we have established several NCAM (CD56)-positive immortalized human dystrophic and non-dystrophic myogenic cell lines from DMD and healthy muscles. A pro-inflammatory cytokine, IL-1beta, promoted cell cycle progression of non-dystrophic myogenic cells but not DMD myogenic cells. In contrast, IL-1beta upregulated the Notch ligand Jagged1 gene in DMD myogenic cells but not in non-dystrophic myogenic cells. Knockdown of Jagged1 in DMD myogenic cells restored the IL-1beta-promoted cell cycle progression. Conversely, enforced expression of Jagged1-blocked IL-1beta promoted proliferation of non-dystrophic myogenic cells. In addition, IL-1beta prevented myogenic differentiation of DMD myogenic cells depending on Jagged1 but not of non-dystrophic myogenic cells. These results demonstrate that Jagged1 induced by IL-1beta in DMD myogenic cells modified the action of IL-1beta and reduced the ability to proliferate and differentiate. IL-1beta induced Jagged1 gene expression may be a feedback response to excess stimulation with this cytokine because high IL-1beta (200-1000 pg/ml) induced Jagged1 gene expression even in non-dystrophic myogenic cells. DMD myogenic cells are likely to acquire the susceptibility of the Jagged1 gene to IL-1beta under the microcircumstances in DMD muscles. The present results suggest that Jagged1 induced by IL-1beta plays a crucial role in the loss of muscle regeneration capacity of DMD muscles. The IL 1beta/Jagged1 pathway may be a new therapeutic target to ameliorate exacerbation of muscular dystrophy in a dystrophin-independent manner.

AB - Pelvic angiographic embolization is an effective procedure to provide haemostasis in patients with pelvic fractures. However, management with repeated follow-up radiographs may result in infertility. The study aimed to evaluate the risk of infertility following pelvic fracture treated with pelvic angiographic embolization in female patients. We used data from the National Health Insurance Research Database (NHIRD) provided by the Bureau of National Health Insurance of the Department of Health in Taiwan from the period of 1997-2010. A total of 36 and 18,029 patients were included in the case and control cohorts, respectively. The risk estimations for the case and control cohorts were compared using a Cox's proportional hazards regression model. The significance level was set at <0.05. After adjusting for possible confounding factors, the incidence of infertility in the case cohort was nearly 30.7-fold higher than that in the control cohort (adjust hazard ratio [HR] = 30.7, 95% confidence interval [CI] = 10.643-70.109). Patients between 15-35 years of age had a much higher incidence of infertility in the case cohort than in the control cohort (adjusted HR = 49.9, 95% CI = 15.177 64.099). Taken together, pelvic fractures in female patients treated with arterioembolization for haemostasis might be associated with a higher risk of infertility in Taiwan. Physicians should be aware of the link and inform patients of this risk prior to arterioembolization. PMID- 29194449 TI - Reported selection criteria for adult acquired flatfoot deformity and posterior tibial tendon dysfunction: Are they one and the same? A systematic review. AB - BACKGROUND: Posterior tibial tendon dysfunction (PTTD) and adult acquired flatfoot deformity (AAFD) are used interchangeably, although both suggest quite different pathological processes. OBJECTIVE: To investigate key differences in selection criteria used for inclusion into research studies. METHODS: An electronic database search was performed from inception to June 2016. All primary research articles with clear inclusion/diagnostic criteria for PTTD or AAFD were included in the review. All criteria were extracted and synthesised into one aggregate list. Frequencies of recurring criteria were calculated and reported for each stage of the conditions. RESULTS: Of the potentially eligible papers, 148 (65%) did not specify inclusion/selection criteria for PTTD or AAFD and were excluded. Eligibility criteria were reported 82 times in the 80 included papers, with 69 descriptions for PTTD and 13 for AAFD. After synthesis of criteria from all papers, there were 18 key signs and symptoms. Signs and symptoms were considered to be those relating to tendon pathology and those relating to structural deformity. The total number of individual inclusion/diagnostic criteria ranged from 2 to 9. The majority of articles required signs of both tendon dysfunction and structural deformity (84% for AAFD and 81% for PTTD). Across both groups, the most frequently reported criteria were abduction of the forefoot (11.5% of total criteria used), the presence of a flexible deformity (10.2%) and difficulty performing a single leg heel raise (10.0%). This was largely the case for the PTTD articles, whereas the AAFD articles were more focused on postural issues such as forefoot abduction, medial arch collapse, and hindfoot valgus (each 16.7%). CONCLUSION: As well as synthesising the available literature and providing reporting recommendations, this review has identified that many papers investigating PTTD/AAFD do not state condition-specific selection criteria and that this limits their clinical applicability. Key signs and symptoms of PTTD and AAFD appear similar, except in early PTTD where no structural deformity is present. We recommend that PTTD is the preferred terminology for the condition associated with signs of local tendon dysfunction with pain and/or swelling along the tendon and difficulty with inversion and/or single leg heel raise characterising stage I and difficulty with single leg heel raise and a flexible flatfoot deformity characterizing stage II PTTD. While AAFD may be useful as an umbrella term for acquired flatfoot deformities, the specific associated aetiology should be reported in studies to aid consolidation and implementation of research into practice.

AB - Hormonal changes that cause metabolic complications are a common problem in postmenopausal women. Adiponectin and osteocalcin are cytokines associated with glucose regulatory and insulin sensitized function in postmenopausal stages. The current study investigated the role of adiponectin signaling and osteocalcin mediated function in glucose metabolism in ovariectomized mice. In a mouse menopausal-related metabolic disorder model, overexpression of adiponectin receptor 1 improved glucose tolerance and caused resistance to body weight increase and decline of serum osteocalcin. Furthermore, adiponectin receptor 1 transgenic ovariectomized mice had higher GPRC6A (the putative osteocalcin receptor) expression in muscle tissue. Immunofluorescence indicated that GPRC6A and adiponectin receptor 1 were co-localized in mouse muscle tissues. The present finding suggested adiponectin receptor 1 can mediate the improvement of glucose metabolism by osteocalcin in ovariectomized mice. Our findings imply the possibility to ameliorate menopause-induced metabolic disorder by GPRC6A and adiponectin signaling. PMID- 29194453 TI - Neural correlates of processing sentences and compound words in Chinese. AB - Sentence reading involves multiple linguistic operations including processing of lexical and compositional semantics, and determining structural and grammatical relationships among words. Previous studies on Indo-European languages have associated left anterior temporal lobe (aTL) and left interior frontal gyrus (IFG) with reading sentences compared to reading unstructured word lists. To examine whether these brain regions are also involved in reading a typologically distinct language with limited morphosyntax and lack of agreement between sentential arguments, an FMRI study was conducted to compare passive reading of Chinese sentences, unstructured word lists and disconnected character lists that are created by only changing the order of an identical set of characters. Similar to previous findings from other languages, stronger activation was found in mainly left-lateralized anterior temporal regions (including aTL) for reading sentences compared to unstructured word and character lists. On the other hand, stronger activation was identified in left posterior temporal sulcus for reading unstructured words compared to unstructured characters. Furthermore, reading unstructured word lists compared to sentences evoked stronger activation in left IFG and left inferior parietal lobule. Consistent with the literature on Indo European languages, the present results suggest that left anterior temporal regions subserve sentence-level integration, while left IFG supports restoration of sentence structure. In addition, left posterior temporal sulcus is associated with morphological compounding. Taken together, reading Chinese sentences engages a common network as reading other languages, with particular reliance on integration of semantic constituents. PMID- 29194452 TI - Hyperthyroidism, but not hypertension, impairs PITX2 expression leading to Wnt microRNA-ion channel remodeling. AB - PITX2 is a homeobox transcription factor involved in embryonic left/right signaling and more recently has been associated to cardiac arrhythmias. Genome wide association studies have pinpointed PITX2 as a major player underlying atrial fibrillation (AF). We have previously described that PITX2 expression is impaired in AF patients. Furthermore, distinct studies demonstrate that Pitx2 insufficiency leads to complex gene regulatory network remodeling, i.e. Wnt>microRNAs, leading to ion channel impairment and thus to arrhythmogenic events in mice. Whereas large body of evidences has been provided in recent years on PITX2 downstream signaling pathways, scarce information is available on upstream pathways influencing PITX2 in the context of AF. Multiple risk factors are associated to the onset of AF, such as e.g. hypertension (HTN), hyperthyroidism (HTD) and redox homeostasis impairment. In this study we have analyzed whether HTN, HTD and/or redox homeostasis impact on PITX2 and its downstream signaling pathways. Using rat models for spontaneous HTN (SHR) and experimentally-induced HTD we have observed that both cardiovascular risk factors lead to severe Pitx2 downregulation. Interesting HTD, but not SHR, leads to up regulation of Wnt signaling as well as deregulation of multiple microRNAs and ion channels as previously described in Pitx2 insufficiency models. In addition, redox signaling is impaired in HTD but not SHR, in line with similar findings in atrial-specific Pitx2 deficient mice. In vitro cell culture analyses using gain- and loss-of-function strategies demonstrate that Pitx2, Zfhx3 and Wnt signaling influence redox homeostasis in cardiomyocytes. Thus, redox homeostasis seems to play a pivotal role in this setting, providing a regulatory feedback loop. Overall these data demonstrate that HTD, but not HTN, can impair Pitx2>>Wnt pathway providing thus a molecular link to AF.

PMID- 29194456 TI - Tools for retargeting proteins within Aspergillus nidulans. AB - Endogenously tagging proteins with green fluorescent protein (GFP) enables the visualization of the tagged protein using live cell microscopy. GFP-tagging is widely utilized to study biological processes in model experimental organisms including filamentous fungi such as Aspergillus nidulans. Many strains of A. nidulans have therefore been generated with different proteins endogenously tagged with GFP. To further enhance experimental approaches based upon GFP tagging, we have adapted the GFP Binding Protein (GBP) system for A. nidulans. GBP is a genetically encoded Llama single chain antibody against GFP which binds GFP with high affinity. Using gene replacement approaches, it is therefore possible to link GBP to anchor proteins, which will then retarget GFP-tagged proteins away from their normal location to the location of the anchor-GBP protein. To facilitate this approach in A. nidulans, we made four base plasmid cassettes that can be used to generate gene replacement GBP-tagging constructs by utilizing fusion PCR. Using these base cassettes, fusion PCR, and gene targeting approaches, we generated strains with SPA10-GBP and Tom20-GBP gene replacements. These strains enabled test targeting of GFP-tagged proteins to septa or to the surface of mitochondria respectively. SPA10-GBP is shown to effectively target GFP-tagged proteins to both forming and mature septa. Tom20-GBP has a higher capacity to retarget GFP-tagged proteins being able to relocate all Nup49-GFP from its location within nuclear pore complexes (NPCs) to the cytoplasm in association with mitochondria. Notably, removal of Nup49-GFP from NPCs causes cold sensitivity as does deletion of the nup49 gene. The cassette constructs described facilitate experimental approaches to generate precise protein-protein linkages in fungi. The A. nidulans SPA10-GBP and Tom20-GBP strains can be utilized to modulate other GFP-tagged proteins of interest. PMID- 29194454 TI - Development of a tissue-specific ribosome profiling approach in Drosophila enables genome-wide evaluation of translational adaptations. AB - Recent advances in next-generation sequencing approaches have revolutionized our understanding of transcriptional expression in diverse systems. However, measurements of transcription do not necessarily reflect gene translation, the process of ultimate importance in understanding cellular function. To circumvent this limitation, biochemical tagging of ribosome subunits to isolate ribosome associated mRNA has been developed. However, this approach, called TRAP, lacks quantitative resolution compared to a superior technology, ribosome profiling. Here, we report the development of an optimized ribosome profiling approach in Drosophila. We first demonstrate successful ribosome profiling from a specific tissue, larval muscle, with enhanced resolution compared to conventional TRAP approaches. We next validate the ability of this technology to define genome-wide translational regulation. This technology is leveraged to test the relative contributions of transcriptional and translational mechanisms in the postsynaptic muscle that orchestrate the retrograde control of presynaptic function at the neuromuscular junction. Surprisingly, we find no evidence that significant changes in the transcription or translation of specific genes are necessary to enable retrograde homeostatic signaling, implying that post-translational mechanisms ultimately gate instructive retrograde communication. Finally, we show that a global increase in translation induces adaptive responses in both transcription and translation of protein chaperones and degradation factors to promote cellular proteostasis. Together, this development and validation of tissue-specific ribosome profiling enables sensitive and specific analysis of translation in Drosophila. PMID- 29194457 TI - Olfactory coding in the turbulent realm. AB - Long-distance olfactory search behaviors depend on odor detection dynamics. Due to turbulence, olfactory signals travel as bursts of variable concentration and spacing and are characterized by long-tail distributions of odor/no-odor events, challenging the computing capacities of olfactory systems. How animals encode complex olfactory scenes to track the plume far from the source remains unclear. Here we focus on the coding of the plume temporal dynamics in moths. We compare responses of olfactory receptor neurons (ORNs) and antennal lobe projection neurons (PNs) to sequences of pheromone stimuli either with white-noise patterns or with realistic turbulent temporal structures simulating a large range of distances (8 to 64 m) from the odor source. For the first time, we analyze what information is extracted by the olfactory system at large distances from the source. Neuronal responses are analyzed using linear-nonlinear models fitted with white-noise stimuli and used for predicting responses to turbulent stimuli. We found that neuronal firing rate is less correlated with the dynamic odor time course when distance to the source increases because of improper coding during long odor and no-odor events that characterize large distances. Rapid adaptation during long puffs does not preclude however the detection of puff transitions in PNs. Individual PNs but not individual ORNs encode the onset and offset of odor puffs for any temporal structure of stimuli. A higher spontaneous firing rate coupled to an inhibition phase at the end of PN responses contributes to this coding property. This allows PNs to decode the temporal structure of the odor plume at any distance to the source, an essential piece of information moths can use in their tracking behavior.

PMID- 29194458 TI - Evidence of increasing sedentarism in Mexico City during the last decade: Sitting time prevalence, trends, and associations with obesity and diabetes. AB - INTRODUCTION: Sedentary behaviors such as sitting time are associated with obesity and diabetes independently of total reported physical activity. This study aimed to describe the current sitting time/day prevalence and trends and to examine the association of sitting time with sociodemographic and clinical variables in Mexico City. METHODS: Two cross-sectional representative surveys in Mexico City were used for this analysis (2006: n = 1148 and 2015: n = 1329). Sedentary behavior questions from the International Physical Activity Questionnaire included time spent sitting on a weekday in the last week or on a Wednesday. Sitting time /day was divided into deciles, and participants in the highest decile (>= 420 minutes/day) were classified within the high sitting category; others were classified in the low sitting time category. Multivariate logistic regression was used to evaluate the associations of sitting time with sociodemographic and clinical indicators, controlling for confounders and testing for potential interactions. RESULTS: A total of 13.7% (2006) and 14.8% (2015) adults were classified in the highest sitting time category (>= 420 minutes/day). There was a significant increase in the average sitting time/day between the surveys (216.0 minutes in 2006 vs. 233.3 minutes in 2015, p < 0.001). In 2015, men, those aged 20-49 years, those in low-intensity jobs, students, and those with a high socioeconomic level were more likely to be in the highest sitting time category. Participants with overweight/obesity (OR = 2.37, 95% CI: 1.11, 5.09) and those with high glucose levels (survey finding) (OR = 2.34, 95% CI: 1.04, 5.25) were more likely to report sitting time in the highest category. DISCUSSION: Sitting time/day prevalence increased 8%, and average daily sitting minutes significantly increased by 8.2% (18 minutes) in the nine-year study period (2006-2015). Current public health policies should consider strategies not only for increasing physical activity levels, but also for reducing sitting time/day among the population as a measure to fight the growing epidemic of obesity and diabetes in Mexico. PMID- 29194460 TI - Dynamical system modeling to simulate donor T cell response to whole exome sequencing-derived recipient peptides: Understanding randomness in alloreactivity incidence following stem cell transplantation. AB - Quantitative relationship between the magnitude of variation in minor histocompatibility antigens (mHA) and graft versus host disease (GVHD) pathophysiology in stem cell transplant (SCT) donor-recipient pairs (DRP) is not established. In order to elucidate this relationship, whole exome sequencing (WES) was performed on 27 HLA matched related (MRD), & 50 unrelated donors (URD), to identify nonsynonymous single nucleotide polymorphisms (SNPs). An average 2,463 SNPs were identified in MRD, and 4,287 in URD DRP (p<0.01); resulting peptide antigens that may be presented on HLA class I molecules in each DRP were derived in silico (NetMHCpan ver2.0) and the tissue expression of proteins these were derived from determined (GTex). MRD DRP had an average 3,670 HLA-binding alloreactive peptides, putative mHA (pmHA) with an IC50 of <500 nM, and URD, had 5,386 (p<0.01). To simulate an alloreactive donor cytotoxic T cell response, the array of pmHA in each patient was considered as an operator matrix modifying a hypothetical cytotoxic T cell clonal vector matrix; each responding T cell clone's proliferation was determined by the logistic equation of growth, accounting for HLA binding affinity and tissue expression of each alloreactive peptide. The resulting simulated organ-specific alloreactive T cell clonal growth revealed marked variability, with the T cell count differences spanning orders of magnitude between different DRP. Despite an estimated, uniform set of constants used in the model for all DRP, and a heterogeneously treated group of patients, higher total and organ-specific T cell counts were associated with cumulative incidence of moderate to severe GVHD in recipients. In conclusion, exome wide sequence differences and the variable alloreactive peptide binding to HLA in each DRP yields a large range of possible alloreactive donor T cell responses. Our findings also help understand the apparent randomness observed in the development of alloimmune responses. PMID- 29194461 TI - Evaluation and validation of commercial antibodies for the detection of Shb. AB - Antibodies are among the most important tools for protein detection but, prior to their usage, proper validation of their appropriateness for given applications is required. The utility of an antibody depends on its sensitivity and specificity. We studied these two aspects in a panel of commercial antibodies against Shb, a platform protein involved in receptor tyrosine kinase signalling, but the function of which is still incompletely understood. Several of the antibodies showed shortcomings or were not acceptable for detection of the endogenous protein. The few that could detect Shb were doing so in either western blotting or immunoprecipitation experiments but a given antibody could not work in both applications. This article provides a resource for the available molecular tools that can be used in future research on Shb. PMID- 29194462 TI - New strategies for the development of lipid-lowering therapies to reduce cardiovascular risk. AB - The very high occurrence of cardiovascular events presents a major public health issue, because treatment remains suboptimal. Lowering LDL cholesterol (LDL-C) with statins or ezetimibe in combination with a statin reduces major adverse cardiovascular events. The cardiovascular risk reduction in relation to the absolute LDL-C reduction is linear for most interventions without evidence of attenuation or increase in risk at low LDL-C levels. Opportunities for innovation in dyslipidaemia treatment should address the substantial risk of lipid associated cardiovascular events among patients optimally treated per guidelines but who cannot achieve LDL-C goals and who could benefit from additional LDL-C lowering therapy or experience side effects of statins. Fresh approaches are needed to identify promising drug targets early and develop them efficiently. The Cardiovascular Round Table of the European Society of Cardiology (ESC) convened a workshop to discuss new lipid-lowering strategies for cardiovascular risk reduction. Opportunities to improve treatment approaches and the efficient study of new therapies were explored. Circulating biomarkers may not be fully reliable proxy indicators of the relationship between treatment effect and clinical outcome. Mendelian randomization studies may better inform development strategies and refine treatment targets before Phase 3. Trials should match the drug to appropriate lipid and patient profile, and guidelines may move towards a precision-based approach to individual patient management. Stakeholder collaboration is needed to ensure continued innovation and better international coordination of both regulatory aspects and guidelines. It should be noted that risk may also be addressed through increased attention to other risk factors such as smoking, hypertension, overweight, and inactivity. PMID- 29194464 TI - Computer-aided biomarker discovery for precision medicine: data resources, models and applications. AB - Biomarkers are a class of measurable and evaluable indicators with the potential to predict disease initiation and progression. In contrast to disease-associated factors, biomarkers hold the promise to capture the changeable signatures of biological states. With methodological advances, computer-aided biomarker discovery has now become a burgeoning paradigm in the field of biomedical science. In recent years, the 'big data' term has accumulated for the systematical investigation of complex biological phenomena and promoted the flourishing of computational methods for systems-level biomarker screening. Compared with routine wet-lab experiments, bioinformatics approaches are more efficient to decode disease pathogenesis under a holistic framework, which is propitious to identify biomarkers ranging from single molecules to molecular networks for disease diagnosis, prognosis and therapy. In this review, the concept and characteristics of typical biomarker types, e.g. single molecular biomarkers, module/network biomarkers, cross-level biomarkers, etc., are explicated on the guidance of systems biology. Then, publicly available data resources together with some well-constructed biomarker databases and knowledge bases are introduced. Biomarker identification models using mathematical, network and machine learning theories are sequentially discussed. Based on network substructural and functional evidences, a novel bioinformatics model is particularly highlighted for microRNA biomarker discovery. This article aims to give deep insights into the advantages and challenges of current computational approaches for biomarker detection, and to light up the future wisdom toward precision medicine and nation-wide healthcare. PMID- 29194463 TI - Efficacy of Endoscopic Balloon Dilation for Small Bowel Strictures in Patients With Crohn's Disease: A Nationwide, Multi-centre, Open-label, Prospective Cohort Study. AB - Background and Aims: Endoscopic balloon dilation [EBD] is an alternative to surgery for Crohn's strictures. However, there have been no prospective studies of EBD for small bowel strictures in patients with Crohn's disease [CD]. The aim of this study was to clarify the efficacy and safety of EBD using balloon assisted enteroscopy for small bowel strictures in CD. Methods: This was a nationwide, multi-centre, open-label, prospective cohort study. The subjects were CD patients with at least one symptom [abdominal pain, abdominal bloating, nausea] attributable to small bowel stricture. The primary endpoint related to short-term outcomes was the level of improvement of symptoms evaluated using a 10 cm visual analogue scale [VAS]. Cases in which VAS scores for all symptoms improved 4 weeks after EBD compared with baseline were considered to have short term symptomatic improvement. Factors related to short-term treatment outcomes and safety were investigated as secondary endpoints. Results: A total of 112 patients were enrolled. Seventeen were later excluded because they did not meet the criteria, and the analysis was conducted with the remaining 95 patients. Of these 95 patients, procedure failure occurred in six [6.3%], and short-term symptomatic improvement was achieved in 66 patients [69.5%]. Adverse events were seen in five patients [5%] and all of these improved with conservative treatment. A large dilation diameter of the balloon was a factor contributing to the success of EBD. Conclusions: EBD using balloon-assisted enteroscopy for small bowel strictures in CD patients was shown to be an effective and safe procedure. Clinical trial registry: UMIN000005946. PMID- 29194465 TI - Rehabilitation in dementia care. AB - Multidisciplinary rehabilitation is increasingly accepted as valuable in the management of chronic disease. Whereas traditional rehabilitation models focussed on recovery, maintaining independence and delaying functional decline are now considered worthwhile aims even where full recovery is not feasible. Despite this, rehabilitation is notably absent from dementia care literature and practice. People with dementia report frustration with the lack of availability of structured post-diagnosis pathways like those offered for other conditions. Alternative terms such as 're-ablement' are used to refer to rehabilitation-like services, but lack an evidence-base to guide care. This commentary will discuss possible reasons for the resistance to accept multidisciplinary rehabilitation as part of dementia care, and identifies the value of doing so for people with dementia, their families, and for health professionals. PMID- 29194466 TI - Genome Context Viewer: visual exploration of multiple annotated genomes using microsynteny. AB - Summary: The Genome Context Viewer is a visual data-mining tool that allows users to search across multiple providers of genome data for regions with similarly annotated content that may be aligned and visualized at the level of their shared functional elements. By handling ordered sequences of gene family memberships as a unit of search and comparison, the user interface enables quick and intuitive assessment of the degree of gene content divergence and the presence of various types of structural events within syntenic contexts. Insights into functionally significant differences seen at this level of abstraction can then serve to direct the user to more detailed explorations of the underlying data in other interconnected, provider-specific tools.

PMID- 29194467 TI - Sleep hygiene education as a treatment of insomnia: a systematic review and meta analysis. AB - Background: Sleep hygiene education (SHE) is commonly used as a treatment of insomnia in general practice. Whether SHE or cognitive-behavioural therapy for insomnia (CBT-I), a treatment with stronger evidence base, should be provided first remains unclear. Objective: To review the efficacy of SHE for poor sleep or insomnia. Methods: We systematically searched six key electronic databases up until May 2017. Two researchers independently selected relevant publications, extracted data and evaluated methodological quality according to the Cochrane criteria. Results: Twelve of 15 studies compared SHE with CBT-I, three with mindfulness-based therapy, but none with sham or no treatment. General knowledge about sleep, substance use, regular exercise and bedroom arrangement were commonly covered; sleep-wake regularity and avoidance of daytime naps in seven programs, but stress management in only five programs. Major findings include (i) there were significant pre- to post-treatment improvements following SHE, with small to medium effect size; (ii) SHE was significantly less efficacious than CBT I, with difference in effect size ranging from medium to large; (iii) pre- to post-treatment improvement and SHE-CBT-I difference averaged at 5% and 8% in sleep-diary-derived sleep efficiency, respectively, and two points in Pittsburgh Sleep Quality Index; (iv) only subjective measures were significant and (v) no data on acceptability, adherence, understanding and cost-effectiveness. Conclusions: Although SHE is less effective than CBT-I, unanswered methodological and implementation issues prevent a firm conclusion to be made on whether SHE has a role in a stepped-care model for insomnia in primary care. PMID- 29194468 TI - Characteristics of Faecal Microbiota in Paediatric Crohn's Disease and Their Dynamic Changes During Infliximab Therapy. AB - Background: Crohn's disease [CD] is known to be associated with gut microbial dysbiosis. Infliximab [IFX] is increasingly used to treat paediatric CD; however, it is not clear how the gut microbiota is modified during IFX treatment. The aim of this study was to characterise the faecal microbiota community composition in paediatric CD patients and to assess its dynamic changes during IFX therapy. Methods: A 16S rRNA sequencing approach was applied to determine the compositions of microbial communities in faecal samples. The composition and function of the faecal microbiota were compared between CD patients and healthy controls. Results: Characteristics of faecal microbiome composition in paediatric CD patients before IFX treatment were represented by a lower biodiversity, a gain in Enterococcus, and a significant loss in multiple short-chain fatty acid [SCFA] producing bacteria, including Anaerostipes, Blautia, Coprococcus, Faecalibacterium, Lachnospira, Odoribacter, Roseburia, Ruminococcus, and Sutterella. Additionally, alterations were observed in metabolic functions of the gut microbial community in CD. IFX treatment increased the biodiversity of gut microbiota and shifted its composition as well as its functional capabilities in the paediatric CD patients toward a healthy status. However, multiple SCFA producing taxa were not significantly expanded. The sustained response of paediatric CD patients to IFX was associated with abundance of SCFA-producing bacteria. Conclusions: A lower biodiversity with alterations in the composition and function of faecal microbial community, characterising gut microbial dysbiosis, was observed in Chinese paediatric CD patients. IFX diminished the CD associated gut microbial dysbiosis but was deficient in increasing certain SCFA producing taxa. PMID- 29194469 TI - bioBakery: a meta'omic analysis environment.

AB - Motivation: Differential network analysis is an important way to understand network rewiring involved in disease progression and development. Building differential networks from multiple 'omics data provides insight into the holistic differences of the interactive system under different patient-specific groups. DINGO was developed to infer group-specific dependencies and build differential networks. However, DINGO and other existing tools are limited to analyze data arising from a single platform, and modeling each of the multiple 'omics data independently does not account for the hierarchical structure of the data. Results: We developed the iDINGO R package to estimate group-specific dependencies and make inferences on the integrative differential networks, considering the biological hierarchy among the platforms. A Shiny application has also been developed to facilitate easier analysis and visualization of results, including integrative differential networks and hub gene identification across platforms.

PMID- 29194473 TI - ESMO Consensus Conference on malignant lymphoma: general perspectives and recommendations for the clinical management of the elderly patient with malignant lymphoma. AB - The European Society for Medical Oncology (ESMO) consensus conference on mature B cell lymphomas and chronic lymphocytic leukaemia (CLL) was held on 20 June 2015 in Lugano, Switzerland, and included a multidisciplinary panel of 25 leading experts. The aim of the conference was to develop recommendations on critical subjects difficult to consider in detail in the ESMO Clinical Practice Guidelines. The following areas were identified: (1) the elderly patient, (2) prognostic factors suitable for clinical use, and (3) the 'ultra-high-risk' group. Before the conference, the expert panel was divided into three working groups; each group focused on one of these areas in order to address clinically relevant questions relating to that topic. All relevant scientific literature, as identified by the experts, was reviewed in advance. During the consensus conference, each working group developed recommendations to address each of the four questions assigned to their group. These recommendations were presented to the entire panel and a consensus was reached. This consensus, which was further developed in continuous post-meeting discussions, formed the basis of three manuscripts, each covering one of the three key areas identified. This manuscript presents the consensus recommendations regarding the clinical management of elderly patients diagnosed with malignant lymphoma. Four clinically-relevant topics identified by the panel were: 1) how to define patient fitness, 2) assessing quality of life, 3) diagnostic work-up and 4) clinical management of elderly patients with lymphoma. Each of these key topics is addressed in the context of five different lymphoma entities, namely: CLL, follicular lymphoma, mantle cell lymphoma, peripheral T-cell lymphoma and diffuse large B-cell lymphoma. Results, including a summary of evidence supporting each recommendation, are detailed in this manuscript. PMID- 29194475 TI - Analysis of the Strength of Legal Firearms Restrictions for Perpetrators of Domestic Violence and Their Associations With Intimate Partner Homicide. AB - In this research, we estimate the association of firearm restrictions for domestic violence offenders with intimate partner homicides (IPHs) on the basis of the strength of the policies. We posit that the association of firearm laws with IPHs depends on the following characteristics of the laws: 1) breadth of coverage of high-risk individuals and situations restricted; 2) power to compel firearm surrender or removal from persons prohibited from having firearms; and 3) systems of accountability that prevent those prohibited from doing so from obtaining guns. We conducted a quantitative policy evaluation using annual state level data from 1980 through 2013 for 45 US states. Based on the results of a series of robust, negative binomial regression models with state fixed effects, domestic violence restraining order firearm-prohibition laws are associated with 10% reductions in IPH. Statistically significant protective associations were evident only when restraining order prohibitions covered dating partners (-11%) and ex parte orders (-12%). Laws prohibiting access to those convicted of nonspecific violent misdemeanors were associated with a 24% reduction in IPH rates; there was no association when prohibitions were limited to domestic violence. Permit-to-purchase laws were associated with 10% reductions in IPHs. These findings should inform policymakers considering laws to maximize protections against IPH. PMID- 29194474 TI - Power Analysis for Genetic Association Test (PAGEANT) provides insights to challenges for rare variant association studies. AB - Motivation: Genome-wide association studies are now shifting focus from analysis of common to rare variants. As power for association testing for individual rare variants may often be low, various aggregate level association tests have been proposed to detect genetic loci. Typically, power calculations for such tests require specification of large number of parameters, including effect sizes and allele frequencies of individual variants, making them difficult to use in practice. We propose to approximate power to a varying degree of accuracy using a smaller number of key parameters, including the total genetic variance explained by multiple variants within a locus. Results: We perform extensive simulation studies to assess the accuracy of the proposed approximations in realistic settings. Using these simplified power calculations, we develop an analytic framework to obtain bounds on genetic architecture of an underlying trait given results from genome-wide association studies with rare variants. Finally, we provide insights into the required quality of annotation/functional information for identification of likely causal variants to make meaningful improvement in power.

PMID- 29194477 TI - Regulatory feedback loops bridge the human gene regulatory network and regulate carcinogenesis. AB - The development of disease involves a systematic disturbance inside cells and is associated with changes in the interactions or regulations among genes forming biological networks. The bridges inside a network are critical in shortening the distances between nodes. We observed that, inside the human gene regulatory network, one strongly connected core bridged the whole network. Other regulations outside the core formed a weakly connected component surrounding the core like a peripheral structure. Furthermore, the regulatory feedback loops (FBLs) inside the core compose an interface-like structure between the core and periphery. We then denoted the regulatory FBLs as the interface core. Notably, both the cancer associated and essential biomolecules and regulations were significantly overrepresented in the interface core. These results implied that the interface core is not only critical for the network structure but central in cellular systems. Furthermore, the enrichment of the cancer-associated and essential regulations in the interface core might be attributed to its bridgeness in the network. More importantly, we identified one regulatory FBL between HNF4A and NR2F2 that possesses the highest bridgeness in the interface core. Further investigation suggested that the disturbance of the HNF4A-NR2F2 FBL might protect tumor cells from apoptotic processes. Our results emphasize the relevance of the regulatory network properties to cellular systems and might reveal a critical role of the interface core in cancer.

AB - Motivation: The haploid mammalian Y chromosome is usually under-represented in genome assemblies due to high repeat content and low depth due to its haploid nature. One strategy to ameliorate the low coverage of Y sequences is to experimentally enrich Y-specific material before assembly. As the enrichment process is imperfect, algorithms are needed to identify putative Y-specific reads prior to downstream assembly. A strategy that uses k-mer abundances to identify such reads was used to assemble the gorilla Y. However, the strategy required the manual setting of key parameters, a time-consuming process leading to sub-optimal assemblies. Results: We develop a method, RecoverY, that selects Y-specific reads by automatically choosing the abundance level at which a k-mer is deemed to originate from the Y. This algorithm uses prior knowledge about the Y chromosome of a related species or known Y transcript sequences. We evaluate RecoverY on both simulated and real data, for human and gorilla, and investigate its robustness to important parameters. We show that RecoverY leads to a vastly superior assembly compared to alternate strategies of filtering the reads or contigs. Compared to the preliminary strategy used by Tomaszkiewicz et al., we achieve a 33% improvement in assembly size and a 20% improvement in the NG50, demonstrating the power of automatic parameter selection.

AB - Legionellaceae are composed of a single genus, Legionella, which is currently comprised of over 52 species. L. pneumophila, L. micdadei, L. longbeachae, and L. dumoffi are clinically considered the most important, with L. pneumophila causing >90%1,7 of cases of legionnaires disease (LD). Since LD's recognition in 1976 following an outbreak of pneumonia involving delegates of an American Legion convention in Philadelphia, there has been increased awareness and importance of the isolation, detection, and reporting of these cases. Herein we describe the unfortunate case of a 7 month old boy with undiagnosed LD that lead to respiratory insufficiency, sepsis, multisystem organ failure and death. Laboratory investigation methods, and clinical and pathological findings are discussed. PMID- 29194479 TI - Emergence of an MDR Klebsiella pneumoniae ST231 producing OXA-232 and RmtF in Switzerland.

PMID- 29194484 TI - Robotic pericardial patch repair of the bronchus intermedius after bronchogenic cyst removal. AB - Bronchogenic cysts are often asymptomatic mediastinal masses that are usually diagnosed as incidental findings. Surgical resection can be performed with robotic surgery, and if repair of the airway is needed, this can be achieved by direct closure or by applying a pericardial patch. We present a case of a 45-year old woman diagnosed with a mass in the visceral mediastinum. She had undergone resection adopting a 4-armed, completely portal robotic technique. However, the removal of the cyst had led to a large tear in the bronchus intermedius. The bronchus was then repaired with a 2.4-cm-long pericardial patch sutured with the V-lock sutures. The entire procedure was performed in a total span of 189 min, and the patient was discharged on postoperative Day 2. The robotic platform, with articulated instruments, allowed complex suturing while conversion was not required. To our knowledge, the robotic surgery has not been applied in bronchial repairs by pericardial patches, and this case is the first of its kind. PMID- 29194483 TI - BmILF and i-motif structure are involved in transcriptional regulation of BmPOUM2 in Bombyx mori. AB - Guanine-rich and cytosine-rich DNA can form four-stranded DNA secondary structures called G-quadruplex (G4) and i-motif, respectively. These structures widely exist in genomes and play important roles in transcription, replication, translation and protection of telomeres. In this study, G4 and i-motif structures were identified in the promoter of the transcription factor gene BmPOUM2, which regulates the expression of the wing disc cuticle protein gene (BmWCP4) during metamorphosis. Disruption of the i-motif structure by base mutation, anti-sense oligonucleotides (ASOs) or inhibitory ligands resulted in significant decrease in the activity of the BmPOUM2 promoter. A novel i-motif binding protein (BmILF) was identified by pull-down experiment. BmILF specifically bound to the i-motif and activated the transcription of BmPOUM2. The promoter activity of BmPOUM2 was enhanced when BmILF was over-expressed and decreased when BmILF was knocked-down by RNA interference. This study for the first time demonstrated that BmILF and the i-motif structure participated in the regulation of gene transcription in insect metamorphosis and provides new insights into the molecular mechanism of the secondary structures in epigenetic regulation of gene transcription. PMID- 29194485 TI - Self-protection of cytosolic malate dehydrogenase against oxidative stress in Arabidopsis. AB - Plant malate dehydrogenase (MDH) isoforms are found in different cell compartments and function in key metabolic pathways. It is well known that the chloroplastic NADP-dependent MDH activities are strictly redox regulated and controlled by light. However, redox dependence of other NAD-dependent MDH isoforms have been less studied. Here, we show by in vitro biochemical characterization that the major cytosolic MDH isoform (cytMDH1) is sensitive to H2O2 through sulfur oxidation of cysteines and methionines. CytMDH1 oxidation affects the kinetics, secondary structure, and thermodynamic stability of cytMDH1. Moreover, MS analyses and comparison of crystal structures between the reduced and H2O2-treated cytMDH1 further show that thioredoxin-reversible homodimerization of cytMDH1 through Cys330 disulfide formation protects the protein from overoxidation. Consistently, we found that cytosolic thioredoxins interact specifically with cytMDH in a yeast two-hybrid system. Importantly, we also show that cytosolic and chloroplastic, but not mitochondrial NAD-MDH activities are sensitive to H2O2 stress in Arabidopsis. NAD-MDH activities decreased both in a catalase2 mutant and in an NADP-thioredoxin reductase mutant, emphasizing the importance of the thioredoxin-reducing system to protect MDH from oxidation in vivo. We propose that the redox switch of the MDH activity contributes to adapt the cell metabolism to environmental constraints. PMID- 29194486 TI - Cortical Auditory-Evoked Responses in Preterm Neonates: Revisited by Spectral and Temporal Analyses. AB - Characteristic preterm EEG patterns of "Delta-brushes" (DBs) have been reported in the temporal cortex following auditory stimuli, but their spatio-temporal dynamics remains elusive. Using 32-electrode EEG recordings and co-registration of electrodes' position to 3D-MRI of age-matched neonates, we explored the cortical auditory-evoked responses (AERs) after 'click' stimuli in 30 healthy neonates aged 30-38 post-menstrual weeks (PMW). (1) We visually identified auditory-evoked DBs within AERs in all the babies between 30 and 33 PMW and a decreasing response rate afterwards. (2) The AERs showed an increase in EEG power from delta to gamma frequency bands over the middle and posterior temporal regions with higher values in quiet sleep and on the right. (3) Time-frequency and averaging analyses showed that the delta component of DBs, which negatively peaked around 550 and 750 ms over the middle and posterior temporal regions, respectively, was superimposed with fast (alpha-gamma) oscillations and corresponded to the late part of the cortical auditory-evoked potential (CAEP), a feature missed when using classical CAEP processing. As evoked DBs rate and AERs delta to alpha frequency power decreased until full term, auditory-evoked DBs are thus associated with the prenatal development of auditory processing and may suggest an early emerging hemispheric specialization. PMID- 29194488 TI - Impact of unresolved neutropenia in patients with neutropenia and invasive aspergillosis: a post hoc analysis of the SECURE trial. AB - Background: Historically, baseline neutropenia and lack of neutrophil recovery have been associated with poor outcomes in invasive aspergillosis (IA). It is unclear how treatment with the new Aspergillus-active triazoles isavuconazole and voriconazole affects outcomes in neutropenic patients with IA. Methods: A post hoc analysis of the Phase 3 SECURE trial assessed patients with neutropenia (neutrophil count <0.5 * 109/L for >10 days at baseline) with IA (proven/probable) who had received either isavuconazole or voriconazole. The primary endpoint was all-cause mortality (ACM) through day 42. ACM in patients with resolved versus unresolved neutropenia at day 7 and overall success at end of treatment (EOT) were also assessed. Results: One hundred and forty-two patients with neutropenia and IA were included (isavuconazole n = 78, voriconazole n = 64). ACM through day 42 (primary endpoint), day 7 and EOT were higher for patients with unresolved versus resolved neutropenia at each timepoint (day 42, unresolved: 45.0% isavuconazole, 45.2% voriconazole; resolved: 5.0% isavuconazole, 5.9% voriconazole; day 7, unresolved: 31.0% isavuconazole, 29.8% voriconazole; resolved: 5.0% isavuconazole, 5.9% voriconazole; EOT, unresolved: 48.6% isavuconazole, 36.4% voriconazole; resolved: 5.0% isavuconazole, 14.3% voriconazole). ACM was significantly higher for isavuconazole-treated patients with unresolved versus resolved neutropenia (day 7, P = 0.031; day 42, P < 0.001; EOT, P < 0.001). In voriconazole-treated patients, ACM was significantly higher among patients with unresolved versus resolved neutropenia at day 42 (P = 0.002) and numerically higher at day 7 and EOT (P > 0.05 for both). Conclusions: Isavuconazole had comparable efficacy and safety to voriconazole in neutropenic patients with IA. Resolution of neutropenia was associated with improved outcomes. PMID- 29194487 TI - Comparative Genomics of an Unusual Biogeographic Disjunction in the Cotton Tribe (Gossypieae) Yields Insights into Genome Downsizing. AB - Long-distance insular dispersal is associated with divergence and speciation because of founder effects and strong genetic drift. The cotton tribe (Gossypieae) has experienced multiple transoceanic dispersals, generating an aggregate geographic range that encompasses much of the tropics and subtropics worldwide. Two genera in the Gossypieae, Kokia and Gossypioides, exhibit a remarkable geographic disjunction, being restricted to the Hawaiian Islands and Madagascar/East Africa, respectively. We assembled and use de novo genome sequences to address questions regarding the divergence of these two genera from each other and from their sister-group, Gossypium. In addition, we explore processes underlying the genome downsizing that characterizes Kokia and Gossypioides relative to other genera in the tribe. Using 13,000 gene orthologs and synonymous substitution rates, we show that the two disjuncts last shared a common ancestor ~5 Ma, or half as long ago as their divergence from Gossypium. We report relative stasis in the transposable element fraction. In comparison to Gossypium, there is loss of ~30% of the gene content in the two disjunct genera and a history of genome-wide accumulation of deletions. In both genera, there is a genome-wide bias toward deletions over insertions, and the number of gene losses exceeds the number of gains by ~2- to 4-fold. The genomic analyses presented here elucidate genomic consequences of the demographic and biogeographic history of these closest relatives of Gossypium, and enhance their value as phylogenetic outgroups. PMID- 29194490 TI - The Response of Prostate Smooth Muscle Cells to Testosterone Is Determined by the Subcellular Distribution of the Androgen Receptor. AB - Androgen signaling in prostate smooth muscle cells (pSMCs) is critical for the maintenance of prostate homeostasis, the alterations of which are a central aspect in the development of pathological conditions. Testosterone can act through the classic androgen receptor (AR) in the cytoplasm, eliciting genomic signaling, or through different types of receptors located at the plasma membrane for nongenomic signaling. We aimed to find evidence of nongenomic testosterone signaling mechanisms in pSMCs and their participation in cell proliferation, differentiation, and the modulation of the response to lipopolysaccharide. We demonstrated that pSMCs can respond to testosterone by a rapid activation of ERK1/2 and Akt. Furthermore, a pool of ARs localized at the cell surface of pSMCs is responsible for a nongenomic testosterone-induced increase in cell proliferation. Through membrane receptor stimulation, testosterone favors a muscle phenotype, indicated by an increase in smooth muscle markers. We also showed that the anti-inflammatory effects of testosterone, capable of attenuating lipopolysaccharide-induced proinflammatory actions, are promoted only by receptors located inside the cell. We postulate that testosterone might perform prohomeostatic effects through intracellular-initiated mechanisms by modulating cell proliferation and inflammation, whereas some pathological, hyperproliferative actions would be induced by membrane-initiated nongenomic signaling in pSMCs. PMID- 29194489 TI - mirDIP 4.1-integrative database of human microRNA target predictions. AB - MicroRNAs are important regulators of gene expression, achieved by binding to the gene to be regulated. Even with modern high-throughput technologies, it is laborious and expensive to detect all possible microRNA targets. For this reason, several computational microRNA-target prediction tools have been developed, each with its own strengths and limitations. Integration of different tools has been a successful approach to minimize the shortcomings of individual databases. Here, we present mirDIP v4.1, providing nearly 152 million human microRNA-target predictions, which were collected across 30 different resources. We also introduce an integrative score, which was statistically inferred from the obtained predictions, and was assigned to each unique microRNA-target interaction to provide a unified measure of confidence. We demonstrate that integrating predictions across multiple resources does not cumulate prediction bias toward biological processes or pathways. mirDIP v4.1 is freely available at http://ophid.utoronto.ca/mirDIP/.

AB - Importance: Emergency resuscitation of critically ill patients can challenge team communication and situational awareness. Tools facilitating team performance may enhance patient safety. Objectives: To determine resuscitation team members' perceptions of the Situational Awareness Display's utility. Design: We conducted focus groups with healthcare providers during Situational Awareness Display development. After simulations assessing the display, we conducted debriefs with participants. Setting: Dual site tertiary care level 1 trauma centre in Ottawa, Canada. Participants: We recruited by email physicians, nurses and respiratory therapist. Intervention: Situational Awareness Display, a visual cognitive aid that provides key clinical information to enhance resuscitation team communication and situational awareness. Main outcomes and measures: Themes emerging from focus groups and simulation debriefs. Three reviewers independently coded and analysed transcripts using content qualitative analysis. Results: We recruited a total of 33 participants in two focus groups (n = 20) and six simulation debriefs with three 4-5 member teams (n = 13). Majority of participants (10/13) strongly endorsed the Situational Awareness Display's utility in simulation (very or extremely useful). Focus groups and debrief themes included improved perception of patient data, comprehension of context and ability to project to future decisions. Participants described potentially positive and negative impacts on patient safety and positive impacts on provider performance and team communication. Participants expressed a need for easy data entry incorporated into clinical workflow and training on how to use the display. Conclusion: Emergency resuscitation team participants felt the Situational Awareness Display has potential to improve provider performance, team communication and situational awareness, ultimately enhancing quality of care.

AB - Objective: Establishing one price for all bundled services for a particular illness, which has become the key to healthcare reform efforts, is designed to encourage health professionals to coordinate their care for patients. Limited information is available, however, concerning whether bundled payments are associated with changes in patient outcomes. Nationwide longitudinal population based data were used to examine the effect of bundled payments on hip fracture outcomes. Design: An interrupted time series design with a comparison group. Setting: General acute care hospitals throughout Taiwan. Participants: A total of 178 586 hip fracture patients admitted over the period 2007-12 identified from the Taiwan's National Health Insurance Research Database. Intervention: Bundled payments for hip fractures were implemented in Taiwan in January 2010. Main Outcome Measures: The 30-day unplanned readmission and postdischarge mortality. Segmented generalized estimating equation regression models were used after adjustment for trends, patient, physician and hospital characteristics to assess the effect of bundled payments on 30-day outcomes for hip fracture compared with a reference condition. Results: The 30-day unplanned readmission rate for hip fracture showed a relative decreasing trend after the implementation of bundled payments compared with the trend before the implementation relative to that of the reference condition. Conclusions: This finding might imply that the implementation of bundled payments encourages health professionals to coordinate their care, leading to reduced readmission for hip fracture.

PMID- 29194496 TI - Cambial pinning relates wood anatomy to ecophysiology in the African tropical tree Maesopsis eminii. AB - A better understanding and prediction of the impact of changing climate on tree stem growth could greatly benefit from the combination of anatomical and ecophysiological knowledge, yet the majority of studies focus on one research field only. We propose an approach that combines the method of pinning (cambial wounding) to timestamp anatomical X-ray computed microtomography images with continuous measurements of sap flow and stem diameter variations. By pinning the cambium of well-watered and drought-treated young African tropical trees of the species Maesopsis eminii Engl. we could quantify wood formation during a specific period of time and relate it to tree physiology and prevailing microclimate. Integrating continuous plant measurements and high-frequency pinning proved very useful to visualize and quantify the effects on stem growth of drought in M. eminii. Wood formation completely stopped during drought, and was associated with a strong shrinkage in stem diameter. Next, an unexpected increase in stem diameter was observed during drought, probably caused by root pressure, but not accompanied by wood formation. Our proposed approach of combining continuous plant measurements with cambial pinning is very promising to relate ecophysiology to stem anatomy and to understand the mechanisms underlying tree stem growth and bridge the gaps between the two research fields.

AB - The ability to correctly understand the emotional expression of another person is essential for social relationships and appears to be a partly inherited trait. The neuropeptides oxytocin and vasopressin have been shown to influence this ability as well as face processing in humans. Here, recognition of the emotional content of faces and voices, separately and combined, was investigated in 492 subjects, genotyped for 25 single nucleotide polymorphisms (SNPs) in eight genes encoding proteins important for oxytocin and vasopressin neurotransmission. The SNP rs4778599 in the gene encoding aryl hydrocarbon receptor nuclear translocator 2 (ARNT2), a transcription factor that participates in the development of hypothalamic oxytocin and vasopressin neurons, showed an association that survived correction for multiple testing with emotion recognition of audio-visual stimuli in women (n = 309). This study demonstrates evidence for an association that further expands previous findings of oxytocin and vasopressin involvement in emotion recognition. PMID- 29194500 TI - EANO guidelines for the diagnosis and treatment of ependymal tumors. AB - Ependymal tumors are rare CNS tumors and may occur at any age, but their proportion among primary brain tumors is highest in children and young adults. Thus, the level of evidence of diagnostic and therapeutic interventions is higher in the pediatric compared with the adult patient population.The diagnosis and disease staging is performed by craniospinal MRI. Tumor classification is achieved by histological and molecular diagnostic assessment of tissue specimens according to the World Health Organization (WHO) classification 2016. Surgery is the crucial initial treatment in both children and adults. In pediatric patients with intracranial ependymomas of WHO grades II or III, surgery is followed by local radiotherapy regardless of residual tumor volume. In adults, radiotherapy is employed in patients with anaplastic ependymoma WHO grade III, and in case of incomplete resection of WHO grade II ependymoma. Chemotherapy alone is reserved for young children <12 months and for adults with recurrent disease when further surgery and irradiation are no longer feasible. A gross total resection is the mainstay of treatment in spinal ependymomas, and radiotherapy is reserved for incompletely resected tumors. Nine subgroups of ependymal tumors across different anatomical compartments (supratentorial, posterior fossa, spinal) and patient ages have been identified with distinct genetic and epigenetic alterations, and with distinct outcomes. These findings may lead to more precise diagnostic and prognostic assessments, molecular subgroup-adapted therapies, and eventually new recommendations pending validation in prospective studies.

PMID- 29194509 TI - The influence of increasing temperature and CO2 concentration on recent growth of old-growth larch: contrasting responses at leaf and stem processes derived from tree-ring width and stable isotopes. AB - Time series of tree-ring growth show significant increases since the early 1970s at the alpine tree line, with simultaneously increasing temperatures and atmospheric CO2 concentration. For a comprehensive understanding of this growth change, the physiological response patterns at both the leaf and stem level need to be separately analyzed and identified, and can be retrieved from tree-ring growth and isotope (delta13C, delta18O) series. In this study, we assessed the relative contribution of environmental factors to interannual tree-ring variability by multivariate linear mixed-effects models and the dual isotope approach on a dataset of tree-ring records of ~400-year-old larch (Larix decidua Mill.) from a non-water-limited high-elevation site in the Swiss Alps. The models suggest that summer temperatures and the recent lack of larch budmoth outbreaks were most important for explaining growth variations and trends, while a significant direct effect of the continuously increasing CO2 concentration could not be confirmed. In contrast, delta13C and delta18O, which are strongly influenced by fractionation changes in the leaf, clearly reflected the impact of air humidity (precipitation and vapor pressure deficit) and CO2 concentration: the increase in (delta13C-derived) intrinsic water-use efficiency over the second half of the 20th century suggests an increase in carbon assimilation as a result of enhanced CO2 concentration. The tree-ring delta18O largely reflected recent precipitation as source water, thus indicating a low variability in stomatal conductance, which was confirmed by the dual isotope approach. These leaf-level effects were not reflected in stem growth as they may have been masked by the temperature-caused growth limitation controlling the allocation of increased amounts of photosynthates into wood growth. Our approach demonstrates that the identification of different roles of environmental factors on leaf and stem processes helps to improve the assessment of site-specific changes of carbon fluxes and growth performance under future environmental conditions. PMID- 29194510 TI - Correlation of biologically effective dose and the tumor control in Stage I (<5 cm) non-small cell lung cancer with stereotactic ablative radiotherapy: a single institutional cohort study. AB - Backgrounds: Stereotactic ablative radiotherapy (SABR) is one of the newly developed innovative radiotherapy and of which optimal dose prescription needs to be standardized. We aimed to investigate the dose-response relationship for patients with SABR. Methods: Fifty-three patients with Stage I non-small cell lung cancer patients, who underwent SABR between November 2006 and January 2015, were evaluated retrospectively. Thirteen patients (24.5%), who refused the surgery were included and 40 patients (75.5%) were medically inoperable at diagnosis. The median age was 74 years. The median SABR dose was 50 Gy in 3-8 fractions and the median biologically effective dose (BED;alpha/beta = 10) was 105.6 Gy (range: 60-160.53 Gy). Results: The median follow-up was 37.1 months. The 1 and 3 year local control rates were 91.7% and 85.1%. The 3 year overall and progression-free survival rate were 63.3% and 47.5%, respectively, and freedom from progression was 62.2%. Local control rate and 3-year overall survival according to tumor size was 100% and 79.4% in T1 tumors in a while 61.8% and 45% in T2a tumors. The 3-year local and regional control by BED10 was 79.4% and 69.4% in <=100 Gy vs. 89.1% and 100% in >100 Gy (P = 0.526, 0.004). Dyspnea more than Grade 3 was reported in six (11.3%) patients and Grade 1 chest pain was shown in five (9.4%) patients. Conclusions: The excellent regional control was conferred with a prescription of more than BED10 of 100 Gy, which also might be needed to achieve better local tumor control in T2a patients with tolerable lung function. PMID- 29194511 TI - Prolyl isomerization of the CENP-A N-terminus regulates centromeric integrity in fission yeast. AB - Centromeric identity and chromosome segregation are determined by the precise centromeric targeting of CENP-A, the centromere-specific histone H3 variant. The significance of the amino-terminal domain (NTD) of CENP-A in this process remains unclear. Here, we assessed the functional significance of each residue within the NTD of CENP-A from Schizosaccharomyces pombe (SpCENP-A) and identified a proline rich 'GRANT' (Genomic stability-Regulating site within CENP-A N-Terminus) motif that is important for CENP-A function. Through sequential mutagenesis, we show that GRANT proline residues are essential for coordinating SpCENP-A centromeric targeting. GRANT proline-15 (P15), in particular, undergoes cis-trans isomerization to regulate chromosome segregation fidelity, which appears to be carried out by two FK506-binding protein (FKBP) family prolyl cis-trans isomerases. Using proteomics analysis, we further identified the SpCENP-A localizing chaperone Sim3 as a SpCENP-A NTD interacting protein that is dependent on GRANT proline residues. Ectopic expression of sim3+ complemented the chromosome segregation defect arising from the loss of these proline residues. Overall, cis-trans proline isomerization is a post-translational modification of the SpCENP-A NTD that confers precise propagation of centromeric integrity in fission yeast, presumably via targeting SpCENP-A to the centromere. PMID- 29194512 TI - Alcohol Relapse After Liver Transplantation for Alcoholic Cirrhosis-Impact on Liver Graft and Patient Survival: A Meta-analysis. AB - Aim: We performed meta-analysis to determine effect of alcohol relapse after liver transplantation (LT) for alcoholic cirrhosis on graft histology and survival. Methods: Studies were selected using following criteria: (a) LT for alcoholic cirrhosis, (b) reporting data on liver histology and/or patient survival among relapsers and abstainers, (c) minimum follow-up of 3 years. Random effects model was used to pool data to compare relapsers and abstainers on liver histology and patient survival. Results: On analysis of seven studies, pooled prevalence of self-reported alcohol relapse was 26.3% (18.0-36.7%) over median (range) follow-up of 6.0 (3.7-8.3) years, with annual alcohol relapse rate of 4.7% (3.0-6.4%) for any alcohol use and 2.9% (0.5-5.3%) for heavy alcohol use. Relapsers compared to abstainers had higher odds for graft steatosis [4.1 (2.4 6.9)], steatohepatitis [4.5 (1.4-14.2)], alcoholic hepatitis [9.3 (1.01-85)], advanced fibrosis or cirrhosis [8.4 (3.5-20)]. Relapsers were over 3-fold more likely to die at 10 years of follow-up: [3.67 (1.42-9.50)] without differences in overall or 5-year survival. Recurrent alcoholic cirrhosis occurring in 9% of biopsied patients and 2% of all transplants was responsible for about 20% of all deaths on follow-up after LT. Extra-hepatic malignancy, and cardiovascular events were common causes for patient mortality. Conclusion: Alcohol relapse after LT for alcoholic cirrhosis negatively impacts the graft and long-term patient survival. Studies are needed to develop strategies to reduce alcohol relapse after LT for alcoholic cirrhosis. Short Summary: Alcohol relapse in liver transplant recipients can negatively affect graft histology and patient survival. Strategies to reduce alcohol relapse are needed to preserve graft function?

AB - In order to extend the knowledge of the composition of the anopheline community and the seasonal variation related to anthropogenic modifications in the city of Puerto Iguazu, adult females were captured between 2009 and 2012. Samples were collected in three environments with different degrees of anthropogenic modification: urban, periurban, and wild. Alpha diversity was evaluated as the 'true' diversity of the species in each environment. Among environments, range abundance curves were used to compare the composition, abundance, and uniformity of species and cluster analysis was used to analyze the similarities and differences. The temporal distribution was analyzed and the relative abundance of the species captured was correlated with meteorological variables. A total of 4,565 females, belonging to seven species: Anopheles albitarsis s.s. (Lynch Arribalzaga), Anopheles argyritarsis (Robineau-Desvoidy), Anopheles deaneorum (Rosa-Freitas), Anopheles fluminensis (Root), Anopheles mediopunctatus (Theobald), Anopheles strodei s.l. (Root), and Anopheles triannulatus s.l. (Neiva and Pinto) were captured. The wild environment showed higher abundance, diversity, and greater uniformity reflected on the less sharp area of the range abundance curve. Species richness was the same in the wild and periurban environments. Higher abundances were observed in summer during the months with higher temperatures. Although the wild environment showed greater Anopheles abundances and diversity, specific richness and species complementarity were similar among the three environments studied. Thus, the periurban environment would turn into a transition zone of great epidemiological importance due to the introduction of people in this environment, which represents a potential risk of malaria transmission in the area.

AB - Nanodosimetry is a branch of dosimetry for investigation and modeling of the interaction pattern of ionizing radiation in nanometre site-sizes (at unit density), which dates back to the 1970's (Pszona S. A track ion counter. Proceedings of Fifth Symposium on Microdosimetry EUR 5452 d-e-f, Published by the Commission of the European Communities, Luxemburg, pp. 1107-1122 (1976)). To date, the different experimental approaches have lead to developing of three fully functional nanodosimeters: the Jet Counter operated at NCBJ, the Ion Counter operated at PTB and Startrack Counter operated at INFN-LNL. Descriptions of each nanodosimeter as well as of the techniques used to investigate the track structure of ionizing particles are presented.

AB - Missense mutations in the dystrophin protein can cause Duchenne muscular dystrophy (DMD) or Becker muscular dystrophy (BMD) through an undefined pathomechanism. In vitro studies suggest that missense mutations in the N terminal actin-binding domain (ABD1) cause protein instability, and cultured myoblast studies reveal decreased expression levels that can be restored to wild type with proteasome inhibitors. To further elucidate the pathophysiology of missense dystrophin in vivo, we generated two transgenic mdx mouse lines expressing L54R or L172H mutant dystrophin, which correspond to missense mutations identified in human patients with DMD or BMD, respectively. Our biochemical, histologic and physiologic analysis of the L54R and L172H mice show decreased levels of dystrophin which are proportional to the phenotypic severity. Proteasome inhibitors were ineffective in both the L54R and L172H mice, yet mice homozygous for the L172H transgene were able to express even higher levels of dystrophin which caused further improvements in muscle histology and physiology. Given that missense dystrophin is likely being degraded by the proteasome but whole body proteasome inhibition was not possible, we screened for ubiquitin conjugating enzymes involved in targeting dystrophin to the proteasome. A myoblast cell line expressing L54R mutant dystrophin was screened with an siRNA library targeting E1, E2 and E3 ligases which identified Amn1, FBXO33, Zfand5 and Trim75. Our study establishes new mouse models of dystrophinopathy and identifies candidate E3 ligases that may specifically regulate dystrophin protein turnover in vivo. PMID- 29194516 TI - Deficits in Cortical Suppression During Vocalization are Associated With Structural Abnormalities in the Arcuate Fasciculus in Early Illness Schizophrenia and Clinical High Risk for Psychosis. AB - Self-generated speech produces a smaller N1 amplitude in the auditory-evoked potential than externally generated speech; this phenomenon is known as N1 suppression. Schizophrenia patients show less N1-suppression than healthy controls. This failure to self-suppress may underlie patients' characteristic tendency to misattribute self-generated thoughts and actions to external sources. While the cause of N1-suppression deficits to speech in schizophrenia remains unclear, structural damage to the arcuate fasciculus is a candidate, due to its ostensible role in transmitting the efference copy of the motor plan to speak. Fifty-one patients with early illness schizophrenia (ESZ), 40 individuals at clinical high-risk for psychosis (CHR), and 59 healthy control (HC) participants underwent an electroencephalogram while they spoke and then listened to a recording of their speech. N1-suppression to the spoken sounds was calculated. Participants also underwent a diffusion-tensor imaging (DTI) scan, from which the arcuate fasciculus and pyramidal tract were extracted with deterministic tractography. ESZ patients exhibited significantly less N1-suppression to self generated speech than HC participants, with CHR participants exhibiting intermediate levels. ESZ patients also exhibited structural abnormalities in the arcuate fasciculus-specifically, reduced fractional anisotropy and increased radial diffusivity-relative to both HC and CHR. There were no between-group differences in the structural integrity of the pyramidal tract. Finally, level of N1-suppression was linearly related to the structural integrity of the arcuate fasciculus, but not the pyramidal tract, across groups. These results suggest that the self-suppression deficits to willed speech consistently observed in schizophrenia patients may be caused, at least in part, by structural damage to the arcuate fasciculus. PMID- 29194517 TI - A Switch and Wave of Neuronal Activity in the Cerebral Cortex During the First Second of Conscious Perception. AB - Conscious perception occurs within less than 1 s. To study events on this time scale we used direct electrical recordings from the human cerebral cortex during a conscious visual perception task. Faces were presented at individually titrated visual threshold for 9 subjects while measuring broadband 40-115 Hz gamma power in a total of 1621 intracranial electrodes widely distributed in both hemispheres. Surface maps and k-means clustering analysis showed initial activation of visual cortex for both perceived and non-perceived stimuli. However, only stimuli reported as perceived then elicited a forward-sweeping wave of activity throughout the cerebral cortex accompanied by large-scale network switching. Specifically, a monophasic wave of broadband gamma activation moves through bilateral association cortex at a rate of approximately 150 mm/s and eventually reenters visual cortex for perceived but not for non-perceived stimuli. Meanwhile, the default mode network and the initial visual cortex and higher association cortex networks are switched off for the duration of conscious stimulus processing. Based on these findings, we propose a new "switch-and-wave" model for the processing of consciously perceived stimuli. These findings are important for understanding normal conscious perception and may also shed light on its vulnerability to disruption by brain disorders. PMID- 29194518 TI - Coincidental ganglionated plexus modification during radiofrequency pulmonary vein isolation and post-ablation arrhythmia recurrence. AB - Aims: Vagal responses (VR) during left atrial ablation for atrial fibrillation (AF) treatment have been reported to be associated with less recurrences, presumably because they are a sign of ganglionated plexi modification. Our objective was to evaluate whether coincidentally elicited VR during left atrial ablation are associated with lower AF recurrence rates. Methods and results: This is a post hoc analysis of a prospective study of 291 patients with paroxysmal AF undergoing radiofrequency pulmonary vein isolation (PVI). Vagal responses were defined as episodes of heart rate <40 bpm or asystole lasting >5 s elicited during energy application. Sixty-eight patients (23.4%) had a VR during ablation. In Kaplan-Meier analysis, mean recurrence-free survival was 449 days (95% confidence interval 411-488) in patients with VR when compared with 435 days (95% confidence interval 415-455) in those without (P = 0.310). The 12-month recurrence rate estimates were 25 and 27%, respectively. In an unadjusted Cox model, VR was associated with an odds ratio for recurrence of 0.77 (95% confidence interval 0.46-1.28). Conclusion: Coincidentally elicited VR during radiofrequency PVI in patients with paroxysmal AF do not appear to be related to lower risk of arrhythmia recurrence. This may mean that, even if a VR is truly a sign of coincidental ablation of a ganglionated plexus, this does not necessarily mean that a therapeutic modification has been effected, at least to a degree associated with clinical benefit. PMID- 29194519 TI - Development of an Analytical Procedure for the Determination of Multiclass Compounds for Forensic Veterinary Toxicology. AB - Reported here is a new analytical multiclass method based on QuEChERS technique, which has proven to be effective in diagnosing fatal poisoning cases in animals. This method has been developed for the determination of analytes in liver samples comprising rodenticides, carbamate and organophosphorus pesticides, coccidiostats and mycotoxins. The procedure entails addition of acetonitrile and sodium acetate to 2 g of homogenized liver sample. The mixture was shaken intensively and centrifuged for phase separation, which was followed by an organic phase transfer into a tube containing sorbents (PSA and C18) and magnesium sulfate, then it was centrifuged, the supernatant was filtered and analyzed by liquid chromatography tandem mass spectrometry. A validation of the procedure was performed. Repeatability variation coefficients <15% have been achieved for most of the analyzed substances. Analytical conditions allowed for a successful separation of variety of poisons with the typical screening detection limit at <=10 MUg/kg levels. The method was used to investigate more than 100 animals poisoning incidents and proved that is useful to be used in animal forensic toxicology cases. PMID- 29194521 TI - Chylopericardium. PMID- 29194522 TI - Morphology and Polytene Chromosomes of a New Species of Simulium (Trichodagmia) (Diptera: Simuliidae) from the Espinhaco Mountains of Brazil. AB - The species richness of black flies in the Simulium (Trichodagmia) orbitale (Diptera: Simuliidae) species group is greatest in southern Brazil, where 9 of 19 species are found. A new species in the S. orbitale group was collected during a survey of black flies in Minas Gerais state, Brazil, in the Espinhaco Mountains, an area rich in endemic taxa. The new species is morphologically similar to Simulium guianense Wise (Diptera: Simuliidae), the main vector of the causal agent of onchocerciasis in Brazil and Venezuela. It can be identified in the male by the unpatterned scutum and slightly concave ventral plate with a prominent median projection, in the female by the bilobate anal lobe, in the pupa by the 12 slender gill filaments with nonsclerotized apices, branching in a rake-like pattern, and in the larva by the elongated abdominal segments V-VIII and ventrolaterally lobulate segment IX. The polytene chromosomes have one unique fixed inversion in the IS arm, relative to all other Brazilian members of the group, confirming the morphological evidence of a distinct species. PMID- 29194520 TI - Trajectories and Drivers of Genome Evolution in Surface-Associated Marine Phaeobacter. AB - The extent of genome divergence and the evolutionary events leading to speciation of marine bacteria have mostly been studied for (locally) abundant, free-living groups. The genus Phaeobacter is found on different marine surfaces, seems to occupy geographically disjunct habitats, and is involved in different biotic interactions, and was therefore targeted in the present study. The analysis of the chromosomes of 32 closely related but geographically spread Phaeobacter strains revealed an exceptionally large, highly syntenic core genome. The flexible gene pool is constantly but slightly expanding across all Phaeobacter lineages. The horizontally transferred genes mostly originated from bacteria of the Roseobacter group and horizontal transfer most likely was mediated by gene transfer agents. No evidence for geographic isolation and habitat specificity of the different phylogenomic Phaeobacter clades was detected based on the sources of isolation. In contrast, the functional gene repertoire and physiological traits of different phylogenomic Phaeobacter clades were sufficiently distinct to suggest an adaptation to an associated lifestyle with algae, to additional nutrient sources, or toxic heavy metals. Our study reveals that the evolutionary trajectories of surface-associated marine bacteria can differ significantly from free-living marine bacteria or marine generalists. PMID- 29194523 TI - Modified Levator Muscle Resection Using Putterman Muller's Muscle-Conjunctival Resection-Ptosis Clamp. AB - Background: The traditional technique for levator muscle resection includes a time-consuming dissection procedure that causes tissue trauma and swelling. The Putterman ptosis clamp has been popularly used in recent years for conjunctival mullerectomy. In this paper, we describe a modified surgical technique for ptosis treatment using the Putterman ptosis clamp. The modified technique improves the surgical results of levator muscle resection. Objectives: We performed a retrospective case-series study to determine the outcomes and complications associated with the use of the Putterman ptosis clamp in levator muscle resection. Methods: Adults aged >=18 years with moderate-to-severe ptosis underwent the modified technique for levator muscle resection. We first performed dissection to expose the aponeurosis and tarsus. Then, we placed the Putterman ptosis clamp to measure redundant aponeurotic and septal tissues and to perform the resection. Following the adjustment of the eyelid fissure, we refixed the levator muscle to the tarsus with 4-0 vicryl stitches. Results: Seventeen patients (34 eyes) were included in the study. Of the 34 eyes, 31 (91.2%) experienced the complete resolution of ptosis after the surgery. One patient (2 eyes, 5.9%) had mild bilateral dermatochalasis and received revision surgery 6 months postoperative. One patient (1 eye, 2.9%) lost the crease of the left eye and received revision surgeries 2 and 6 months after the first surgery. No residual ptosis or severe adverse events were noted in the patients. Conclusions: Modified levator muscle resection using the Putterman ptosis clamp is an effective procedure for ptosis treatment. Level of Evidence 4: PMID- 29194524 TI - Functional sequencing read annotation for high precision microbiome analysis. AB - The vast majority of microorganisms on Earth reside in often-inseparable environment-specific communities-microbiomes. Meta-genomic/-transcriptomic sequencing could reveal the otherwise inaccessible functionality of microbiomes. However, existing analytical approaches focus on attributing sequencing reads to known genes/genomes, often failing to make maximal use of available data. We created faser (functional annotation of sequencing reads), an algorithm that is optimized to map reads to molecular functions encoded by the read-correspondent genes. The mi-faser microbiome analysis pipeline, combining faser with our manually curated reference database of protein functions, accurately annotates microbiome molecular functionality. mi-faser's minutes-per-microbiome processing speed is significantly faster than that of other methods, allowing for large scale comparisons. Microbiome function vectors can be compared between different conditions to highlight environment-specific and/or time-dependent changes in functionality. Here, we identified previously unseen oil degradation-specific functions in BP oil-spill data, as well as functional signatures of individual specific gut microbiome responses to a dietary intervention in children with Prader-Willi syndrome. Our method also revealed variability in Crohn's Disease patient microbiomes and clearly distinguished them from those of related healthy individuals. Our analysis highlighted the microbiome role in CD pathogenicity, demonstrating enrichment of patient microbiomes in functions that promote inflammation and that help bacteria survive it.

PMID- 29194526 TI - Bacterial Infections After Burn Injuries: Impact of Multidrug Resistance. AB - Patients who are admitted to the hospital after sustaining a large burn injury are at high risk for developing hospital-associated infections. If patients survive the initial 72 hours after a burn injury, infections are the most common cause of death. Ventilator-associated pneumonia is the most important infection in this patient population. The risk of infections caused by multidrug-resistant bacterial pathogens increases with hospital length of stay in burn patients. In the first days of the postburn hospitalization, more susceptible, Gram-positive organisms predominate, whereas later more resistant Gram-negative organisms are found. These findings impact the choice of empiric antibiotics in critically ill burn patients. A proactive infection control approach is essential in burn units. Furthermore, a multidisciplinary approach to burn patients with a team that includes an infectious disease specialist and a pharmacist in addition to the burn surgeon is highly recommended. PMID- 29194530 TI - A review of computational approaches for analysis of hepatitis C virus-mediated liver diseases. AB - Chronic infection of hepatitis C virus (HCV) leads to severe life-threatening liver diseases such as cirrhosis of liver, fibrosis and hepatocellular carcinoma (HCC). Severity of the disease infects >180 million people worldwide. In recent years, many computational approaches have been proposed to study and analyze the progression of liver fibrosis, HCC and other liver diseases developed from chronic HCV infection. In this article, we review the literature published in this area of study. Here we categorize all the approaches into two basic groups: analyzing gene expression and studying protein-protein interaction network among HCV-infected human proteins. We also review functional and pathway-enrichment analysis of HCV-interacted human proteins, which gives a clear understanding of functional perturbations leading to hepatocarcinogenesis. Topological analysis of HCV-human protein interaction network and HCV-HCC association network reveals important information of hepatocarcinogenesis progression in liver tissue. We compare the results of topological analysis performed in different studies. Moreover we observe that the HCV-interacted human proteins, which are also responsible for HCC progression, have relatively higher degree and betweenness centrality than that of the other HCV-interacted proteins. PMID- 29194531 TI - Conservative surgery versus colorectal resection in deep endometriosis infiltrating the rectum: a randomized trial. AB - STUDY QUESTION: Is there a difference in functional outcome between conservative versus radical rectal surgery in patients with large deep endometriosis infiltrating the rectum 2 years postoperatively? SUMMARY ANSWER: No evidence was found that functional outcomes differed when conservative surgery was compared to radical rectal surgery for deeply invasive endometriosis involving the bowel. WHAT IS KNOWN ALREADY: Adopting a conservative approach to the surgical management of deep endometriosis infiltrating the rectum, by employing shaving or disc excision, appears to yield improved digestive functional outcomes. However, previous comparative studies were not randomized, introducing a possible bias regarding the presumed superiority of conservative techniques due to the inclusion of patients with more severe deep endometriosis who underwent colorectal resection. STUDY DESIGN SIZE, DURATION: From March 2011 to August 2013, we performed a 2-arm randomized trial, enroling 60 patients with deep endometriosis infiltrating the rectum up to 15 cm from the anus, measuring more than 20 mm in length, involving at least the muscular layer in depth and up to 50% of rectal circumference. No women were lost to follow-up. PARTICIPANTS/MATERIALS, SETTING, METHODS: Patients were enroled in three French university hospitals and had either conservative surgery, by shaving or disc excision, or radical rectal surgery, by segmental resection. Randomization was performed preoperatively using sequentially numbered, opaque, sealed envelopes, and patients were informed of the results of randomization. The primary endpoint was the proportion of patients experiencing one of the following symptoms: constipation (1 stool/>5 consecutive days), frequent bowel movements (>=3 stools/day), defecation pain, anal incontinence, dysuria or bladder atony requiring self-catheterization 24 months postoperatively. Secondary endpoints were the values of the Visual Analog Scale (VAS), Knowles-Eccersley-Scott-Symptom Questionnaire (KESS), the Gastrointestinal Quality of Life Index (GIQLI), the Wexner scale, the Urinary Symptom Profile (USP) and the Short Form 36 Health Survey (SF36). MAIN RESULTS AND THE ROLE OF CHANCE: A total of 60 patients were enroled. Among the 27 patients in the conservative surgery arm, two were converted to segmental resection (7.4%). In each group, 13 presented with at least one functional problem at 24 months after surgery (48.1 versus 39.4%, OR = 0.70, 95% CI 0.22-2.21). The intention-to-treat comparison of the overall scores on KESS, GIQLI, Wexner, USP and SF36 did not reveal significant differences between the two arms. Segmental resection was associated with a significant risk of bowel stenosis. LIMITATIONS REASONS FOR CAUTION: The inclusion of only large infiltrations of the rectum does not allow the extrapolation of conclusions to small nodules of <20 mm in length. The presumption of a 40% difference favourable to conservative surgery in terms of postoperative functional outcomes resulted in a lack of power to demonstrate a difference for the primary endpoint. WIDER IMPLICATIONS OF THE FINDINGS: Conservative surgery is feasible in patients managed for large deep rectal endometriosis. The trial does not show a statistically significant superiority of conservative surgery for mid-term functional digestive and urinary outcomes in this specific population of women with large involvement of the rectum. There is a higher risk of rectal stenosis after segmental resection, requiring additional endoscopic or surgical procedures.

PMID- 29194532 TI - Identification of more than 100 structurally unique DNA-phosphate adducts formed during rat lung carcinogenesis by the tobacco-specific nitrosamine 4 (methylnitrosamino)-1-(3-pyridyl)-1-butanone. AB - The tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is a powerful lung carcinogen in animal models and is considered a causative factor for lung cancer in people who use tobacco products. NNK undergoes metabolic activation-a critical step in its mechanism of carcinogenesis to an intermediate which reacts with DNA to form pyridyloxobutyl DNA base and phosphate adducts. Another important metabolic pathway of NNK is its conversion to 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), which similarly forms pyridylhydroxybutyl DNA base adducts that have been characterized previously. In this study, we investigated the potential formation of pyridylhydroxybutyl DNA phosphate adducts. We report the characterization and quantitation of 107 structurally unique pyridylhydroxybutyl DNA phosphate adducts in the lungs of rats treated chronically with a carcinogenic dose of 5 ppm of NNK in their drinking water for up to 70 weeks, by using a novel liquid chromatography nanoelectrospray ionization-high-resolution tandem mass spectrometry method. Our findings demonstrate that pyridylhydroxybutyl phosphate adducts account for 38-55 and 34-40% of all the measured pyridine-containing DNA adducts in rat lung and liver, respectively, upon treatment with NNK. Some of the pyridylhydroxybutyl DNA phosphate adducts persisted in both tissues for over 70 weeks, suggesting that they could be potential biomarkers of chronic exposure to NNK and NNAL. This study provides comprehensive characterization and relative quantitation of a panel of NNK/NNAL-derived DNA phosphate adducts, thus identifying NNK as the source of the most structurally diverse set of DNA adducts identified to date from any carcinogen. PMID- 29194534 TI - Why not try harder? Computational approach to motivation deficits in neuro psychiatric diseases. AB - Motivation deficits, such as apathy, are pervasive in both neurological and psychiatric diseases. Even when they are not the core symptom, they reduce quality of life, compromise functional outcome and increase the burden for caregivers. They are currently assessed with clinical scales that do not give any mechanistic insight susceptible to guide therapeutic intervention. Here, we present another approach that consists of phenotyping the behaviour of patients in motivation tests, using computational models. These formal models impose a precise and operational definition of motivation that is embedded in decision theory. Motivation can be defined as the function that orients and activates the behaviour according to two attributes: a content (the goal) and a quantity (the goal value). Decision theory offers a way to quantify motivation, as the cost that patients would accept to endure in order to get the benefit of achieving their goal. We then review basic and clinical studies that have investigated the trade-off between the expected cost entailed by potential actions and the expected benefit associated with potential rewards. These studies have shown that the trade-off between effort and reward involves specific cortical, subcortical and neuromodulatory systems, such that it may be shifted in particular clinical conditions, and reinstated by appropriate treatments. Finally, we emphasize the promises of computational phenotyping for clinical purposes. Ideally, there would be a one-to-one mapping between specific neural components and distinct computational variables and processes of the decision model. Thus, fitting computational models to patients' behaviour would allow inferring of the dysfunctional mechanism in both cognitive terms (e.g. hyposensitivity to reward) and neural terms (e.g. lack of dopamine). This computational approach may therefore not only give insight into the motivation deficit but also help personalize treatment. PMID- 29194535 TI - Formation of Protein Disulfide Bonds Catalyzed by OsPDIL1;1 is Mediated by MicroRNA5144-3p in Rice. AB - Correct folding of proteins in the endoplasmic reticulum is important for their stability and function under stress. The protein disulfide isomerase (PDI) OsPDIL1;1 is a key protein-folding catalyst in rice (Oryza sativa L.). Here, microRNA5144 (osa-miR5144-3p) is reported to mediate the formation of protein disulfide bonds via targeting OsPDIL1;1 mRNA in rice seeds and seedlings during development and under conditions of abiotic stress, respectively. Expression analysis of transgenic rice and identification of cleavage sites showed that OsPDIL1;1 mRNA is a target of osa-miR5144-3p. Expression of osa-miR5144-3p and OsPDIL1;1 was shown to be inversely regulated in developing organs and under abiotic stress. The down-regulation of osa-miR5144-3p or overexpression of OsPDIL1;1 in transgenic rice showed increased total protein-disulfide bond content, compared with the wild type. This indicates that protein-disulfide bond formation is enhanced by down-regulation of osa-miR5144-3p or overexpression of OsPDIL1;1. These transgenic rice plants also displayed strong resistance to salinity and mercury stress, in comparison with the wild type. In contrast, the transgenic rice plants overexpressing osa-miR5144-3p or down-regulating OsPDIL1;1 had a lower protein-disulfide bond content; they were susceptible to abiotic stress and produced abnormal grains with small and loosely packed starch granules. These results indicate that protein-disulfide bond formation catalyzed by OsPDIL1;1 is modulated by osa-miR5144-3p in rice during development and is involved in resistance to abiotic stress. PMID- 29194537 TI - Complex Effects of Superior Competitors and Resources on Culex restuans (Diptera: Culicidae) Oviposition. AB - A growing body of literature on mosquito oviposition behavior supports the hypothesis that females place eggs in habitats that provide best available opportunity for growth, development, and maturation of their offspring. We conducted a field experiment to evaluate Culex oviposition behavior in response to the interspecific competitor Aedes triseriatus (Say) (Diptera: Culicidae) larvae, and resources in the form of quantity of plant detritus, and dissolved nitrogen (TN) and phosphorus (TP) derived from that detritus. We tested a set of specific predictions: 1) As a poorer competitor, Culex will avoid ovipositing in containers with superior interspecific competitors; 2) Culex choose oviposition habitats that contain greater amount of resources for the microbial food of their offspring; 3) Sufficiently high resource abundance can override avoidance of oviposition in containers with interspecific competitors. Culex restuans Theobald (Diptera: Culicidae) was the only species ovipositing, and the oviposition responses changed over time. The effect of resources was more important in driving oviposition decisions at the beginning and end of the experiment. The amount of resources, as manifest by TN and TP concentrations, had differential effects on oviposition. At the beginning females laid more eggs in containers with low detritus, which had the highest TN. After that, females preferred those containers with high detritus, which had low TN and high TP. The effect of competitors was important only during the middle of the experiment. Paradoxically, even as a poorer competitor Cx. restuans preferentially oviposited in containers with late-instar Ae. triseriatus, suggesting that the presence of successful heterospecifics indicates a good quality larval habitat. PMID- 29194536 TI - circlncRNAnet: an integrated web-based resource for mapping functional networks of long or circular forms of noncoding RNAs. AB - Background: Despite their lack of protein-coding potential, long noncoding RNAs (lncRNAs) and circular RNAs (circRNAs) have emerged as key determinants in gene regulation, acting to fine-tune transcriptional and signaling output. These noncoding RNA transcripts are known to affect expression of messenger RNAs (mRNAs) via epigenetic and post-transcriptional regulation. Given their widespread target spectrum, as well as extensive modes of action, a complete understanding of their biological relevance will depend on integrative analyses of systems data at various levels. Findings: While a handful of publicly available databases have been reported, existing tools do not fully capture, from a network perspective, the functional implications of lncRNAs or circRNAs of interest. Through an integrated and streamlined design, circlncRNAnet aims to broaden the understanding of ncRNA candidates by testing in silico several hypotheses of ncRNA-based functions, on the basis of large-scale RNA-seq data. This web server is implemented with several features that represent advances in the bioinformatics of ncRNAs: (1) a flexible framework that accepts and processes user-defined next-generation sequencing-based expression data; (2) multiple analytic modules that assign and productively assess the regulatory networks of user-selected ncRNAs by cross-referencing extensively curated databases; (3) an all-purpose, information-rich workflow design that is tailored to all types of ncRNAs.

PMID- 29194539 TI - A 10-year review of health care reform on Family Practice Integrated Care Project Taiwan experience. AB - Objective: Taiwan has launched a Family Practice Integrated Care Project (FPICP) to develop an accountable family doctor system since March 2003. We aim to report the effectiveness of this nationwide demonstration programme over a 10-year period. Methods: Papers and reports related to the FPICP published both in English and in Chinese from 2003 to 2015 were collected systematically based on keywords including 'family doctor', 'primary care', 'integrated care' and 'Taiwan'. Also collected and reviewed were national health insurance administration annual reports and related publications from Taiwan Association of Family Medicine. Quality care indicators including structure, process and outcome for programme monitoring were reported. Results: Up to June 2015, the project had enrolled a total of 10.5% of Taiwan's population. Approximately 24.9% of primary care physicians and 29.7% of community clinics joined the project to serve the members of 426 community health care groups (CHCGs). Compared to non-members, CHCG members received more preventive care services, especially in adult health examination (49% versus 19%), Pap smear (29% versus 22%), elderly influenza vaccination (42% versus 28%) and immunochemical faecal occult blood test (43% versus 31%) (P < 0.01). Members showed a markedly high level of satisfaction (>95%), especially in overall satisfaction, provision of health consultation and information, and improvement in understanding personal health condition. Conclusions: In the future, through the support of family physicians and CHCGs, a person-centred integrated health care delivery system can be an effective solution to the current barriers in the medical care system.

AB - FUS (fused in sarcoma) mislocalization and cytoplasmic aggregation are hallmark pathologies in FUS-related amyotrophic lateral sclerosis and frontotemporal dementia. Many of the mechanistic hypotheses have focused on a loss of nuclear function in the FUS-opathies, implicating dysregulated RNA transcription and splicing in driving neurodegeneration. Recent studies describe an additional somato-dendritic localization for FUS in the cerebral cortex implying a regulatory role in mRNA transport and local translation at the synapse. Here, we report that FUS is also abundant at the pre-synaptic terminal of the neuromuscular junction (NMJ), suggesting an important function for this protein at peripheral synapses. We have previously reported dose and age-dependent motor neuron degeneration in transgenic mice overexpressing human wild-type FUS, resulting in a motor phenotype detected by ~28 days and death by ~100 days. Now, we report the earliest structural events using electron microscopy and quantitative immunohistochemistry. Mitochondrial abnormalities in the pre synaptic motor nerve terminals are detected at postnatal day 6, which are more pronounced at P15 and accompanied by a loss of synaptic vesicles and synaptophysin protein coupled with NMJs of a smaller size at a time when there is no detectable motor neuron loss. These changes occur in the presence of abundant FUS and support a peripheral toxic gain of function. This appearance is typical of a 'dying-back' axonopathy, with the earliest manifestation being mitochondrial disruption. These findings support our hypothesis that FUS has an important function at the NMJ, and challenge the 'loss of nuclear function' hypothesis for disease pathogenesis in the FUS-opathies. PMID- 29194540 TI - How linked are national HIV and SRHR strategies? A review of SRHR and HIV strategies in 60 countries. AB - The connection between HIV and sexual and reproductive health and rights (SRHR) is widely recognised along with the benefits of linking them at the legal/policy, health systems, and service delivery levels. However, despite increased rhetoric about the need for this three-tiered approach, integrated service delivery has not been fully addressed at the legal/policy level through national strategies. Thus a review of HIV and SRHR strategies was conducted for 60 countries, determining the extent to which they reflected the intersections between HIV and SRHR. Each HIV strategy was scored on whether five key SRHR components were incorporated and had an associated measurable target. SRHR strategies were similarly assessed for incorporation of five HIV components and associated targets. HIV strategies had a higher level of inclusion of SRHR components with a global average of 6.6/10 compared to 3.7/10 for SRHR strategies. The highest scoring component was the elimination of mother-to-child transmission of HIV (EMTCT) and the lowest was SRHR of people living with HIV. Countries with higher scores in one strategy tended to have higher scores in the other but there was no difference over time. Whilst there has been increased global commitment since 2004 to link SRHR and HIV, insufficient headway has been made in linking related national strategies. Although EMTCT is included with targets in the majority of HIV and SRHR strategies, the broader SRHR needs of women living with HIV are not. Also, condoms are not being considered an effective triple protection tool. HIV and SRHR strategies provide direction and targets which ultimately may influence funding and vice versa. Therefore, it is essential that these strategies are right-based and incorporate the key connections between SRHR and HIV with measurable targets to realise the full benefits of a joint response. PMID- 29194541 TI - Integrated care: learning between high-income, and low- and middle-income country health systems. AB - Over the past decade, discussion of integrated care has become more widespread and prominent in both high- and low-income health care systems (LMICs). The trend reflects the mismatch between an increasing burden of chronic disease and local health care systems which are still largely focused on hospital-based treatment of individual clinical episodes and also the long-standing proliferation of vertical donor-funded disease-specific programmes in LMICs which have disrupted horizontal, or integrated, care. Integration is a challenging concept to define, in part because of its multiple dimensions and varied scope: from integrated clinical care for individual patients to broader systems integration-or linkage involving a wide range of interconnected services (e.g. social services and health care). In this commentary, we compare integrated care in high- and lower income countries. Although contexts may differ significantly between these settings, there are many common features of how integration has been understood and common challenges in its implementation. We discuss the different approaches to, scope of, and impacts of, integration including barriers and facilitators to the processes of implementation. With the burden of disease becoming more alike across settings, we consider what gains there could be from comparative learning between these settings which have constituted two separate strands of research until now.

PMID- 29194543 TI - Does service integration improve technical quality of care in low-resource settings? An evaluation of a model integrating HIV care into family planning services in Kenya. AB - The aim of this study was to investigate association between HIV and family planning integration and technical quality of care. The study focused on technical quality of client-provider consultation sessions. The cross-sectional study observed 366 client-provider consultation sessions and interviewed 37 health care providers in 12 public health facilities in Kenya. Multilevel random intercept and linear regression models were fitted to the matched data to investigate relationships between service integration and technical quality of care as well as associations between facility-level structural and provider factors and technical quality of care. A sensitivity analysis was performed to test for hidden bias. After adjusting for facility-level structural factors, HIV/family planning integration was found to have significant positive effect on technical quality of the consultation session, with average treatment effect 0.44 (95% CI: 0.63-0.82). Three of the 12 structural factors were significantly positively associated with technical quality of consultation session including: availability of family planning commodities (9.64; 95% CI: 5.07-14.21), adequate infrastructure (5.29; 95% CI: 2.89-7.69) and reagents (1.48; 95% CI: 1.02-1.93). Three of the nine provider factors were significantly positively associated with technical quality of consultation session: appropriate provider clinical knowledge (3.14; 95% CI: 1.92-4.36), job satisfaction (2.02; 95% CI: 1.21-2.83) and supervision (1.01; 95% CI: 0.35-1.68), while workload (-0.88; 95% CI: -1.75 to - 0.01) was negatively associated. Technical quality of the client-provider consultation session was also determined by duration of the consultation and type of clinic visit and appeared to depend on whether the clinic visit occurred early or later in the week. Integration of HIV care into family planning services can improve the technical quality of client-provider consultation sessions as measured by both health facility structural and provider factors. PMID- 29194545 TI - Impact of integration of sexual and reproductive health services on consultation duration times: results from the Integra Initiative. AB - The lack of human resources is a key challenge in scaling up of HIV services in Africa's health care system. Integrating HIV services could potentially increase their effectiveness and optimize the use of limited resources and clinical staff time. We examined the impact of integration of provider initiated HIV counselling and testing (PITC) and family planning (FP counselling and FP provision) services on duration of consultation to assess the impact of PITC and FP integration on staff workload. This study was conducted in 24 health facilities in Kenya under the Integra Initiative, a non-randomized, pre/post intervention trial to evaluate the impact of integrated HIV and sexual and reproductive health services on health and service outcomes. We compared the time spent providing PITC-only services, FP-only services and integrated PITC/FP services. We used log-linear regression to assess the impact of plausible determinants on the duration of clients' consultation times. Median consultation duration times were highest for PITC-only services (30 min), followed by integrated services (10 min) and FP-only services (8 min). Times for PITC-only and FP-only services were 69.7% higher (95% Confidence Intervals (CIs) 35.8-112.0) and 43.9% lower (95% CIs -55.4 to - 29.6) than times spent on these services when delivered as an integrated service, respectively. The reduction in consultation times with integration suggests a potential reduction in workload. The higher consultation time for PITC-only could be because more pre- and post-counselling is provided at these stand-alone services. In integrated PITC/FP services, the duration of the visit fell below that required by HIV testing guidelines, and service mix between counselling and testing substantially changed. Integration of HIV with FP services may compromise the quality of services delivered and care must be taken to clearly specify and monitor appropriate consultation duration times and procedures during the process of integrating HIV and FP services. PMID- 29194544 TI - Numbers, systems, people: how interactions influence integration. Insights from case studies of HIV and reproductive health services delivery in Kenya. AB - Drawing on rich data from the Integra evaluation of integrated HIV and reproductive-health services, we explored the interaction of systems hardware and software factors to explain why some facilities were able to implement and sustain integrated service delivery while others were not. This article draws on detailed mixed-methods data for four case-study facilities offering reproductive health and HIV services between 2009 and 2013 in Kenya: (i) time-series client flow, tracking service uptake for 8841 clients; (ii) structured questionnaires with 24 providers; (iii) in-depth interviews with 17 providers; (iv) workload and facility data using a periodic activity review and cost-instruments; and (v) contextual data on external activities related to integration in study sites. Overall, our findings suggested that although structural factors like stock-outs, distribution of staffing and workload, rotation of staff can affect how integrated care is provided, all these factors can be influenced by staff themselves: both frontline and management. Facilities where staff displayed agency of decision making, worked as a team to share workload and had management that supported this, showed better integration delivery and staff were able to overcome some structural deficiencies to enable integrated care. Poor-performing facilities had good structural integration, but staff were unable to utilize this because they were poorly organized, unsupported or teams were dysfunctional. Conscientious objection and moralistic attitudes were also barriers.Integra has demonstrated that structural integration is not sufficient for integrated service delivery. Rather, our case studies show that in some cases excellent leadership and peer-teamwork enabled facilities to perform well despite resource shortages. The ability to provide support for staff to work flexibly to deliver integrated services and build resilient health systems to meet changing needs is particularly relevant as health systems face challenges of changing burdens of disease, climate change, epidemic outbreaks and more.

PMID- 29194548 TI - DETERMINATION OF THE BACKGROUND OF 3He-FILLED PROPORTIONAL COUNTERS USED FOR LOW LEVEL NEUTRON MEASUREMENTS. AB - Low-level neutron measurements are required for applications such as environmental monitoring, measurements of weak sources and the determination of neutron fluxes at underground laboratories. When analyzing low-level neutron measurements, it is important to be able to distinguish the signal due to neutrons from any background term that may originate within the detector. A solution to this problem has been developed for the case of measurements carried out with 3He spherical proportional counters of the type which are often used in Bonner sphere spectrometers. To determine this background, measurements were carried out in the former UDO underground laboratory of the Physikalisch Technische Bundesanstalt located in the Asse salt mine. The analysis of the data was carried out using Bayesian parameter estimation. The result of the analysis is a very general parameterised function that can be used to describe the pulse height spectrum due to the background of the proportional counters. PMID- 29194547 TI - Neutralizing Antibody Correlates Analysis of Tetravalent Dengue Vaccine Efficacy Trials in Asia and Latin America. AB - Background: In the CYD14 and CYD15 Phase 3 trials of the CYD-TDV dengue vaccine, estimated vaccine efficacy (VE) against symptomatic, virologically confirmed dengue (VCD) occurring between months 13 and 25 was 56.5% and 60.8%, respectively. Methods: Neutralizing antibody titers to the 4 dengue serotypes in the CYD-TDV vaccine insert were measured at month 13 in a randomly sampled immunogenicity subcohort and in all VCD cases through month 25 (2848 vaccine, 1574 placebo) and studied for their association with VCD and with the level of VE to prevent VCD. Results: For each trial and serotype, vaccinees with higher month 13 titer to the serotype had significantly lower risk of VCD with that serotype (hazard ratios, 0.19-0.43 per 10-fold increase). Moreover, for each trial, vaccinees with higher month 13 average titer to the 4 serotypes had significantly higher VE against VCD of any serotype (P < .001). Conclusions: Neutralizing antibody titers postdose 3 correlate with CYD-TDV VE to prevent dengue. High titers associate with high VE for all serotypes, baseline serostatus groups, age groups, and both trials. However, lowest titers do not fully correspond to zero VE, indicating that other factors influence VE. PMID- 29194549 TI - Stability of Synthetic Cathinones in Urine. AB - In this report, we evaluate the concentration, pH, temperature and analyte dependent effects on cathinone stability in preserved human urine. A total of 22 synthetic cathinones were evaluated at 100 ng/mL and 1,000 ng/mL in pH 4 and pH 8 urine over 6 months. Specimens were stored at -20 degrees C, 4 degrees C, 20 degrees C and 32 degrees C. The stability of synthetic cathinones was highly dependent on urine pH and storage temperature. Cathinones were considerably more stable in acidic urine (pH 4) at low temperature. In alkaline urine (pH 8) at 32 degrees C, significant losses (>20%) were observed within hours for the majority of drugs. In contrast, all drugs were stable in frozen and refrigerated urine at pH 4 for the duration of the study. These results highlight the importance of sample storage and the potential for pre-analytical changes in concentration during routine shipping and handling of specimens. Significant structural influence was also observed. Cathinones bearing a tertiary amine (pyrrolidine group) were significantly more stable than their secondary amine counterparts. The methylenedioxy group also exerted a significant stabilizing effect on both the tertiary and secondary amines. In the absence of the methylenedioxy group, no significant differences in stability were observed between the unsubstituted and ring substituted secondary amines. Half-lives at ambient temperature in pH 8 urine ranged from 9 h (3-fluoromethcathinone) to 4.3 months (methylenedioxypyrovalerone and 3,4-methylenedioxy-alpha pyrrolidinobutiophenone), demonstrating the importance of analyte dependence, and the dual stabilizing effect of both the pyrollidine and methylenedioxy groups. Biological evidence may be subjected to a variety of environmental conditions prior to, and during transport to the forensic laboratory. These findings demonstrate the inherent instability of certain cathinone species in biological evidence under some conditions. Moreover, this study highlights the need for quantitative drug findings in toxicological investigations to be interpreted cautiously, and within the context of specimen storage and integrity.

PMID- 29194551 TI - Bypassing bacterial infection in phage display by sequencing DNA released from phage particles. AB - Phage display relies on a bacterial infection step in which the phage particles are replicated to perform multiple affinity selection rounds and to enable the identification of isolated clones by DNA sequencing. While this process is efficient for wild-type phage, the bacterial infection rate of phage with mutant or chemically modified coat proteins can be low. For example, a phage mutant with a disulfide-free p3 coat protein, used for the selection of bicyclic peptides, has a more than 100-fold reduced infection rate compared to the wild-type. A potential strategy for bypassing the bacterial infection step is to directly sequence DNA extracted from phage particles after a single round of phage panning using high-throughput sequencing. In this work, we have quantified the fraction of phage clones that can be identified by directly sequencing DNA from phage particles. The results show that the DNA of essentially all of the phage particles can be 'decoded', and that the sequence coverage for mutants equals that of amplified DNA extracted from cells infected with wild-type phage. This procedure is particularly attractive for selections with phage that have a compromised infection capacity, and it may allow phage display to be performed with particles that are not infective at all.

AB - This manuscript reports the molecular basis for double-stranded DNA (dsDNA) binding of hairpin polyamides incorporating a 5-alkyl thiazole (Nt) unit. Hairpin polyamides containing an N-terminal Nt unit induce higher melting stabilisation of target dsDNA sequences relative to an archetypical hairpin polyamide incorporating an N-terminal imidazole (Im) unit. However, modification of the N terminus from Im to Nt-building blocks results in an increase in dsDNA binding affinity but lower G-selectivity. A general G-selectivity trend is observed for Nt-containing polyamide analogues. G-selectivity increases as the steric bulk in the Nt 5-position increases. Solution-based NMR structural studies reveal differences in the modulation of the target DNA duplex of Nt-containing hairpin polyamides relative to the Im-containing archetype. A structural hallmark of an Nt polyamide*dsDNA complex is a more significant degree of major groove compression of the target dsDNA sequence relative to the Im-containing hairpin polyamide.

Psychiatric nurses and other mental health professionals may see an increase in older adults being referred for treatment. As the most appropriate psychosocial/psychotherapeutic and psychopharmacological treatments are identified for older adults, there are some unique challenges inherent in coordinating the care of this population. It is especially important for prescribing psychiatric advanced practice nurses to update, review, and cross reference older patients' lists of medications at every appointment. Although the obstacles to treating older adults may appear daunting, prudent, responsible, cautious practice should be exercised to ensure they achieve improved functionality, maintain safety, reduce risks, and enhance their quality of life.

AB - Nurses have the same rate of substance use disorders (SUDs) as the general public. Management of nurses with SUDs is moving from being punitive, including public license suspension or revocation, to alternative-to-discipline (ATD) programs that focus on early intervention and non-punitive, confidential help, which often involve continued employment. These programs have good retention rates, and nurses who complete them have fewer criminal convictions and are able to retain their nursing licenses and maintain successful careers in nursing. Barriers to nurses receiving care for SUDs include wide variability in ATD programs, inconsistent funding for treatment, and lack of policies and support for nursing students. Recommendations include changes to nurse practice acts to make ATD programs more uniform, provide adequate funding for all nurses and nursing students, and allow nurses to seek and obtain care without disclosing directly to Boards of Nurses. Colleges of nursing should implement policies to encourage early identification and treatment in nursing students, including ATD and dismissal programs.

AB - Existing research clearly shows that the public-private divide is continuously being challenged, recast and transformed. However, this article argues that a sharp distinction between public and private continues to operate as an important norm for professionals involved in the investigation of insurance claims fraud in Sweden. It shows how power within private insurance companies and the police authority is organized around the public-private divide, which is in turn mobilized to justify repression and to give investigations legitimacy. The article indicates that the formal public-private distinction is far more thoroughly maintained than is suggested by the existing literature. Rather than challenging the centrality of state power, private insurers and the police construct, maintain and have a stake in the reproduction of a state-centric monopoly of crime control.

AB - INTRODUCTION: Data on risk factors for gestational diabetes mellitus (GDM) in primiparous women is limited. The aim of this study was to assess the prevalence of GDM and simultaneously evaluate the impact of age and adiposity in primiparous women at risk of GDM risk. MATERIAL AND METHODS: This observational register based cohort study from the city of Vantaa, Finland, included all 7750 primiparous women giving birth between 2009 and 2015 without previously diagnosed diabetes mellitus. RESULTS: In primiparous women the prevalence of GDM was 16.5% and mean age was 28.2 years (5.2 SD). Primiparous women aged >=35 years had a significantly higher risk for GDM than women aged <25 years [odds ratio (OR) 2.67, 95% confidence interval (CI) 2.13-3.34]. Primiparous women with a pre pregnancy body mass index (BMI) >=30.0 kg/m2 had a significantly higher risk for GDM than women with a pre-pregnancy BMI <25 kg/m2 (OR 5.36, 95% CI 4.53-6.36). The risk of developing GDM showed an increasing trend with increasing age in all BMI categories except the category BMI >=35 kg/m2 . Normal weight women (BMI 20.0 24.9 kg/m2 ) aged 40 years had a significantly higher risk for GDM than normal weight women aged 28 years (OR 1.48, 95% CI 1.01-2.19). CONCLUSIONS: The prevalence of GDM is high in primiparous women. Both age and degree of adiposity influenced the risk for GDM. To reduce GDM risk, adiposity should be prevented already in childhood and primiparity should be encouraged at a younger age. PMID- 29194562 TI - A risk score including microdeletions improves relapse prediction for standard and medium risk precursor B-cell acute lymphoblastic leukaemia in children. AB - To prevent relapse, high risk paediatric acute lymphoblastic leukaemia (ALL) is treated very intensively. However, most patients who eventually relapse have standard or medium risk ALL with low minimal residual disease (MRD) levels. We analysed recurrent microdeletions and other clinical prognostic factors in a cohort of 475 uniformly treated non-high risk precursor B-cell ALL patients with the aim of better predicting relapse and refining risk stratification. Lower relapse-free survival at 7 years (RFS) was associated with IKZF1 intragenic deletions (P < 0.0001); P2RY8-CRLF2 gene fusion (P < 0.0004); Day 33 MRD>5 * 10-5 (P < 0.0001) and High National Cancer Institute (NCI) risk (P < 0.0001). We created a predictive model based on a risk score (RS) for deletions, MRD and NCI risk, extending from an RS of 0 (RS0) for patients with no unfavourable factors to RS2 + for patients with 2 or 3 high risk factors. RS0, RS1, and RS2 + groups had RFS of 93%, 78% and 49%, respectively, and overall survival (OS) of 99%, 91% and 71%. The RS provided greater discrimination than MRD-based risk stratification into standard (89% RFS, 96% OS) and medium risk groups (79% RFS, 91% OS). We conclude that this RS may enable better early therapeutic stratification and thus improve cure rates for childhood ALL. PMID- 29194563 TI - Cyclic analogues of alpha-conotoxin Vc1.1 inhibit colonic nociceptors and provide analgesia in a mouse model of chronic abdominal pain. AB - BACKGROUND AND PURPOSE: Patients with irritable bowel syndrome suffer from chronic visceral pain (CVP) and limited analgesic therapeutic options are currently available. We have shown that alpha-conotoxin Vc1.1 induced activation of GABAB receptors on the peripheral endings of colonic afferents and reduced nociceptive signalling from the viscera. However, the analgesic efficacy of more stable, cyclized versions of Vc1.1 on CVP remains to be determined. EXPERIMENTAL APPROACH: Using ex vivo colonic afferent preparations from mice, we determined the inhibitory actions of cyclized Vc1.1 (cVc1.1) and two cVc1.1 analogues on mouse colonic nociceptors in healthy and chronic visceral hypersensitivity (CVH) states. Using whole-cell patch clamp recordings, we also assessed the inhibitory actions of these peptides on the neuronal excitability of colonic innervating dorsal root ganglion neurons. In vivo, the analgesic efficacy of these analogues was assessed by determining the visceromotor response to colorectal distension in healthy and CVH mice. KEY RESULTS: cVc1.1 and the cVc1.1 analogues, [C2H,C8F]cVc1.1 and [N9W]cVc1.1, all caused concentration-dependent inhibition of colonic nociceptors from healthy mice. Inhibition by these peptides was greater than those evoked by linear Vc1.1 and was substantially greater in colonic nociceptors from CVH mice. cVc1.1 also reduced excitability of colonic dorsal root ganglion neurons, with greater effect in CVH neurons. CVH mice treated with cVc1.1 intra-colonically displayed reduced pain responses to noxious colorectal distension compared with vehicle-treated CVH mice. CONCLUSIONS AND IMPLICATIONS: Cyclic versions of Vc1.1 evoked significant anti-nociceptive actions in CVH states, suggesting that they could be novel candidates for treatment of CVP.

PMID- 29194565 TI - Impaired Langerhans cell migration in psoriasis is due to an altered keratinocyte phenotype induced by interleukin-17. AB - BACKGROUND: Psoriasis is a common skin condition driven by increased expression of interleukin (IL)-17. Langerhans cells (LCs) are epidermal dendritic cells that regulate cutaneous immune responses. Within the uninvolved skin of patients with psoriasis, LCs display impaired migration from the epidermis. OBJECTIVES: To investigate the role of keratinocytes (KCs) in the regulation of LC function and the response of KCs to IL-17. METHODS: KCs were cultured from the uninvolved skin of patients with psoriasis and healthy individuals with or without IL-17 treatment and the conditioned medium examined for its ability to alter LC function in an ex vivo human skin explant model. Furthermore, we examined the effect of IL-17 on LC mobilization in psoriasis by neutralizing IL-17 in the same skin explant model. RESULTS: Conditioned medium from psoriasis KCs inhibited LC migration in healthy skin. Moreover, conditioned medium from healthy KCs treated with IL-17 also inhibited healthy LC migration. Finally, neutralizing IL-17 in psoriasis skin resulted in enhanced LC migration. CONCLUSIONS: Collectively, these data suggest that an altered KC secretome, driven by increased expression of IL-17, is responsible for impaired LC migration in the uninvolved skin of patients with psoriasis.

AB - INTRODUCTION: Denmark was the first country in the world to implement a national, free-for-all offer of prenatal screening for Down syndrome to all pregnant women. It has a high uptake (>90%) compared to other countries. Thus, Denmark offers an interesting case for investigating the consequences of implementing comprehensive, national prenatal screening guidelines. The aim of this study was to describe the historical developments in invasive procedures, pre-/postnatal diagnoses of Down syndrome and Down syndrome live births in the period 1973-2016 in Denmark. MATERIAL AND METHODS: Data on invasive procedures, pre- and postnatal Down syndrome diagnoses were retrieved from the Danish Cytogenetic Central Registry. RESULTS: From 1973 to 1993, screening based on maternal age and high risk indications resulted in a constant increase in invasive procedures. After the introduction of the triple test in 1994, invasive procedures decreased for the first time in 20 years. Following the introduction of an offer of combined screening to all pregnant women in 2004, the number of invasive procedures decreased markedly, while there was a concurrent increase in prenatal diagnoses of Down syndrome. Additionally, the number of Down syndrome live births decreased suddenly and significantly, but subsequently stabilized at 23-35 annual live births. Of these, the majority were diagnosed postnatally. CONCLUSION: Though prenatal screening technologies constantly improve, it was the introduction of and adherence to national guidelines that resulted in marked shifts in screening procedures and outcome in Denmark.

PMID- 29194564 TI - Oxaliplatin-induced enteric neuronal loss and intestinal dysfunction is prevented by co-treatment with BGP-15. AB - BACKGROUND AND PURPOSE: Gastrointestinal side effects of chemotherapy are an under-recognized clinical problem, leading to dose reduction, delays and cessation of treatment, presenting a constant challenge for efficient and tolerated anti-cancer treatment. We have found that oxaliplatin treatment results in intestinal dysfunction, oxidative stress and loss of enteric neurons. BGP-15 is a novel cytoprotective compound with potential HSP72 co-inducing and PARP inhibiting properties. In this study, we investigated the potential of BGP-15 to alleviate oxaliplatin-induced enteric neuropathy and intestinal dysfunction. EXPERIMENTAL APPROACH: Balb/c mice received oxaliplatin (3 mg.kg-1 .day-1 ) with and without BGP-15 (15 mg.kg-1 .day-1 : i.p.) tri-weekly for 14 days. Gastrointestinal transit was analysed via in vivo X-ray imaging, before and after treatment. Colons were collected to assess ex vivo motility, neuronal mitochondrial superoxide and cytochrome c levels and for immunohistochemical analysis of myenteric neurons. KEY RESULTS: Oxaliplatin-induced neuronal loss increased the proportion of neuronal NO synthase-immunoreactive neurons and increased levels of mitochondrial superoxide and cytochrome c in the myenteric plexus. These changes were correlated with an increase in PARP-2 immunoreactivity in the colonic mucosa and were attenuated by BGP-15 co-treatment. Significant delays in gastrointestinal transit, intestinal emptying and pellet formation, impaired colonic motor activity, reduced faecal water content and lack of weight gain associated with oxaliplatin treatment were restored to sham levels in mice co-treated with BGP-15. CONCLUSION AND IMPLICATIONS: Our results showed that BGP 15 ameliorated oxidative stress, increased enteric neuronal survival and alleviated oxaliplatin-induced intestinal dysfunction, suggesting that BGP-15 may relieve the gastrointestinal side effects of chemotherapy. PMID- 29194569 TI - Cohort studies in the context of obstetric and gynecologic research: a methodologic overview. AB - Observational cohort studies represent one of the most powerful designs in epidemiology. They are also the basis of evidence in many areas of obstetric and gynecologic research, given that randomization of women, couples or pregnancies is often impossible or unethical. Indeed, well-conceived cohort studies have led to a better understanding of many important clinical and public health questions over time, including the impact of different exposures on perinatal and pediatric outcomes in pregnant women and their children. In this paper, we describe the main features, challenges, and limitations of cohort studies in the context of obstetric and gynecologic research. As with all epidemiologic studies, cohort studies present numerous challenges and are vulnerable to bias. However, as we describe throughout this review, careful design - from formulating the study question to planning statistical analysis - can reduce the potential for bias. When possible, we also provide examples from the gynecological and obstetrical literature to illustrate the epidemiological challenge and suggest specific readings. PMID- 29194570 TI - Characterization of CD45RO+ memory T lymphocytes in keloid disease. AB - BACKGROUND: Memory T cells, a highly effective subset of T lymphocytes, have been reported to be involved in many inflammatory skin disorders. However, the potential role of memory T cells in keloid disease (KD) remains unclear. OBJECTIVES: Due to their important role in regulating inflammation, we investigated the characteristics of CD45RO+ memory T cells in KD. METHODS: Primary cutaneous cells were isolated from keloid scars and normal skin by enzymic digestion. Peripheral blood mononuclear cells were isolated from a related blood sample, and flow cytometry was applied to identify the phenotypic and functional abnormalities of memory T cells in KD. RESULTS: We observed that the majority of T lymphocytes in keloid scars had the memory phenotype, and a greater number of the CD8+ memory T cells in keloid scars produced lower levels of tumour necrosis factor (TNF)-alpha. This abnormal cytokine production was even more distinct in Forkhead box (FOX)P3- CD8- memory T cells, with lower TNF-alpha production and enhanced interferon-gamma production. Furthermore, FOXP3+ CD8- memory T cells in keloid scars were abnormal, including showing reduced CD25 and cytotoxic T-lymphocyte-associated antigen 4 expression and interleukin-10 production. In addition, a significant decrease in the number of CD4+ CD25high FOXP3+ regulatory T cells was identified in patients with multiple keloid scars. We also found that there was significantly increased infiltration of CD103+ CD8+ memory T cells in keloid scars. CONCLUSIONS: Our findings preliminarily elucidate the abnormalities of CD45RO+ memory T cells in keloid scars and provide early evidence that a disrupted T-cell response contributes to the progression of KD.

AB - BACKGROUND: An altered immune response against Staphylococcus aureus might contribute to inflammation and barrier damage in atopic dermatitis (AD). OBJECTIVES: To profile IgG antibodies against 55 S. aureus antigens in sera of children with mild-to-severe AD and to evaluate the association between IgG levels and disease severity. METHODS: In this cross-sectional study, we included children with AD from two interventional study cohorts, the Shared Medical Appointment (SMA) cohort (n = 131) and the older DAVOS cohort (n = 76). AD severity was assessed using the Self-Administered Eczema Area and Severity Index (SA-EASI) and levels of thymus and activation-regulated chemokine (TARC) in serum. IgG antibody levels against 55 S. aureus antigens were quantified simultaneously using a Luminex assay. Pair-wise correlations were calculated between the 55 IgG levels using the Spearman rank correlation test. Linear regression analysis was performed to test for associations between 55 IgG levels and SA-EASI and TARC, adjusting for age, sex and S. aureus colonization. RESULTS: In the SMA cohort, 16 antigens were associated with SA-EASI and 12 with TARC (10 overlapping antigens; P-values 0.001-0.044). The associated IgG antibodies targeted mainly secreted proteins with immunomodulatory functions. In the DAVOS study, IgG levels against only four and one S. aureus antigen(s) were associated with SA-EASI and TARC, respectively (no overlap). CONCLUSIONS: In young children, severity of AD is associated with an IgG response directed against S. aureus antigens with mainly immunomodulatory functions. These findings encourage further evaluation of the role of S. aureus in the pathogenesis of AD. PMID- 29194573 TI - Stability and Change in Cognitive Status Classification of Black Older Adults. AB - OBJECTIVES: The purpose of this study was to determine whether stability and change in cognitive status are associated with sociodemographic characteristics and health function. DESIGN: Secondary analysis of data. SETTING: Baltimore Study of Black Aging-Patterns of Cognitive Aging. PARTICIPANTS: Community-dwelling black adults (N = 407; mean age 68.6 +/- 9.1). MEASUREMENTS: Baseline (n = 602) and 33-month follow-up (n = 450) assessments of cognition, health, and psychosocial function. RESULTS: For the present analyses, participants were grouped as being cognitively normal (n = 249), having stable mild cognitive impairment (MCI) (n = 32), or being MCI converters (n = 72; normal at baseline, MCI at follow-up) or reverters (n = 54; MCI at baseline, normal at follow-up). Multivariate analysis of variance showed that the groups differed significantly in education and lung function (P < .010). Post hoc analyses indicated that converters had fewer years of education than the other groups, whereas those who were cognitively normal had better lung function than converters and reverters (P < .050). CONCLUSION: These results suggest that education and lung health are associated with patterns of cognitive status change and stability. Future research should account for sociodemographic and health factors when examining stability of cognitive status classifications.

PMID- 29194575 TI - The adjuvant system AS01 up-regulates neutrophil CD14 expression and neutrophil associated antigen transport in the local lymphatic network. AB - The liposome-based adjuvant system AS01 is under evaluation for use in several vaccines in clinical development. We have shown previously that AS01 injected with hepatitis B surface antigen (HBsAg) induces a distinct cellular signature within the draining lymphatics that enhances local lymphocyte recruitment and antigen-specific humoral immunity. Here, we show that AS01-induced neutrophil recruitment is associated with increased expression of CD14 and enhanced antigen uptake capacity in neutrophils from both afferent and efferent lymphatic compartments during the first 48 h after vaccination. Significant and transient increases in CD14 expression on systemic neutrophils were also observed following primary and boost vaccination with HBsAg-AS01; however, they were not observed following additional encounter with HBsAg-alone or HBsAg-alum. These results show that following immunization with AS01, neutrophils expressing higher levels of CD14 are both more abundant and efficient at antigen uptake, warranting further investigation into the role of neutrophil-associated CD14 in the adjuvanticity of AS01. PMID- 29194576 TI - NMR analysis of the backbone dynamics of the small GTPase Rheb and its interaction with the regulatory protein FKBP38. AB - Ras homolog enriched in brain (Rheb) is a small GTPase that regulates mammalian/mechanistic target of rapamycin complex 1 (mTORC1) and, thereby, cell growth and metabolism. Here we show that cycling between the inactive GDP- and the active GTP-bound state modulates the backbone dynamics of a C-terminal truncated form, RhebDeltaCT, which is suggested to influence its interactions. We further investigated the interactions between RhebDeltaCT and the proposed Rheb binding domain of the regulatory protein FKBP38. The observed weak interactions with the GTP-analogue- (GppNHp-) but not the GDP-bound state, appear to accelerate the GDP to GTP exchange, but only very weakly compared to a genuine GEF. Thus, FKBP38 is most likely not a GEF but a Rheb effector that may function in membrane targeting of Rheb. PMID- 29194577 TI - Cerebral cortex development: an outside-in perspective. AB - The cerebral cortex is a complex structure that contains different classes of neurons distributed within six layers and regionally organized into highly specialized areas. Cortical layering arises during embryonic development in an inside-out manner as forebrain progenitors proliferate and generate distinct waves of interneurons and projection neurons. Radial glial cells (RGCs) derive from neuroepithelial cells and are the founding cortical progenitors. At the onset of corticogenesis, RGCs expand their pool by proliferative divisions. As corticogenesis proceeds, they gradually undergo differentiative divisions to either generate neurons directly (direct neurogenesis) or indirectly via production of intermediate progenitors that further divide to generate pairs of neurons (indirect neurogenesis). The fate of RGCs is finely regulated during all the corticogenesis process and depends on time-scaled perception of external signals and expression of intrinsic factors. The present Review focuses on the role of physiological extracellular cues arising from the vicinity of neural progenitors on the regulation of dorsal neurogenesis and cerebral cortex patterning. It further discusses how pathogenic viral factors influence RGC behaviour and disrupt cerebral cortex development.

PMID- 29194579 TI - Targeted gene sequencing and whole-exome sequencing in autopsied fetuses with prenatally diagnosed kidney anomalies. AB - Identification of fetal kidney anomalies invites questions about underlying causes and recurrence risk in future pregnancies. We therefore investigated the diagnostic yield of next-generation sequencing in fetuses with bilateral kidney anomalies and the correlation between disrupted genes and fetal phenotypes. Fetuses with bilateral kidney anomalies were screened using an in-house-designed kidney-gene panel. In families where candidate variants were not identified, whole-exome sequencing was performed. Genes uncovered by this analysis were added to our kidney panel. We identified likely deleterious variants in 11 of 56 (20%) families. The kidney-gene analysis revealed likely deleterious variants in known kidney developmental genes in 6 fetuses and TMEM67 variants in 2 unrelated fetuses. Kidney histology was similar in the latter 2 fetuses-presenting a distinct prenatal form of nephronophthisis. Exome sequencing identified ROBO1 variants in one family and a GREB1L variant in another family. GREB1L and ROBO1 were added to our kidney-gene panel and additional variants were identified. Next generation sequencing substantially contributes to identifying causes of fetal kidney anomalies. Genetic causes may be supported by histological examination of the kidneys. This is the first time that SLIT-ROBO signaling is implicated in human bilateral kidney agenesis. PMID- 29194580 TI - A systems medicine approach reveals disordered immune system and lipid metabolism in multiple sclerosis patients. AB - Identification of autoimmune processes and introduction of new autoantigens involved in the pathogenesis of multiple sclerosis (MS) can be helpful in the design of new drugs to prevent unresponsiveness and side effects in patients. To find significant changes, we evaluated the autoantibody repertoires in newly diagnosed relapsing-remitting MS patients (NDP) and those receiving disease modifying therapy (RP). Through a random peptide phage library, a panel of NDP- and RP-specific peptides was identified, producing two protein data sets visualized using Gephi, based on protein--protein interactions in the STRING database. The top modules of NDP and RP networks were assessed using Enrichr. Based on the findings, a set of proteins, including ATP binding cassette subfamily C member 1 (ABCC1), neurogenic locus notch homologue protein 1 (NOTCH1), hepatocyte growth factor receptor (MET), RAF proto-oncogene serine/threonine-protein kinase (RAF1) and proto-oncogene vav (VAV1) was found in NDP and was involved in over-represented terms correlated with cell-mediated immunity and cancer. In contrast, transcription factor RelB (RELB), histone acetyltransferase p300 (EP300), acetyl-CoA carboxylase 2 (ACACB), adiponectin (ADIPOQ) and phosphoenolpyruvate carboxykinase 2 mitochondrial (PCK2) had major contributions to viral infections and lipid metabolism as significant events in RP. According to these findings, further research is required to demonstrate the pathogenic roles of such proteins and autoantibodies targeting them in MS and to develop therapeutic agents which can ameliorate disease severity.

AB - Implementation of genomic medicine into clinical care continues to increase in prevalence in medical centers worldwide. As defined by the National Human Genome Research Institute, "Genomic medicine is an emerging medical discipline that involves using genomic information about an individual as part of their clinical care...." The genomic information utilized falls broadly into two categories: 1) highly penetrant genetic disorders and 2) pharmacogenomics. Herein, we focus on pharmacogenomics, although the Pharmacogenomics Clinical Annotation Tool (PharmCAT) tool could be extended to include other types of genetic variation. PMID- 29194581 TI - Hodgkin lymphoma: A review and update on recent progress. AB - Hodgkin lymphoma (HL) is a unique hematopoietic neoplasm characterized by cancerous Reed-Sternberg cells in an inflammatory background. Patients are commonly diagnosed with HL in their 20s and 30s, and they present with supradiaphragmatic lymphadenopathy, often with systemic B symptoms. Even in advanced-stage disease, HL is highly curable with combination chemotherapy, radiation, or combined-modality treatment. Although the same doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapeutic regimen has been the mainstay of therapy over the last 30 years, risk-adapted approaches have helped de-escalate therapy in low-risk patients while intensifying treatment for higher risk patients. Even patients who are not cured with initial therapy can often be salvaged with alternate chemotherapy combinations, the novel antibody-drug conjugate brentuximab, or high-dose autologous or allogeneic hematopoietic stem cell transplantation. The programmed death-1 inhibitors nivolumab and pembrolizumab have both demonstrated high response rates and durable remissions in patients with relapsed/refractory HL. Alternate donor sources and reduced intensity conditioning have made allogeneic hematopoietic stem cell transplantation a viable option for more patients. Future research will look to integrate novel strategies into earlier lines of therapy to improve the HL cure rate and minimize long-term treatment toxicities. CA Cancer J Clin 2018;68:116 132.

AB - Despite major scientific investments, safety accounts for significant pipeline attrition, especially in late preclinical and early clinical development. Many failures are due to difficulty interpreting safety signals or difficulty optimizing schedules of compounds with narrow therapeutic margins. Model-informed translation can address these challenges, both through "forward" translation of early signals to future scenarios, as well as through "reverse" translation of safety data into mechanistic insight. PMID- 29194586 TI - Intraindividual Pharmacokinetic Variability: Focus on Small-Molecule Kinase Inhibitors. AB - The magnitude of interindividual pharmacokinetic variability (IIV) of a drug and the factors responsible for this variability are intensively studied before-and sometimes after-registration as crucial information in anticipating and understanding variability in toxicity and efficacy. However, there has been much less attention paid to intraindividual variability, reflecting random or systematic changes in an individual's pharmacokinetics over time. We have chosen to focus on small-molecule kinase inhibitors (SMKIs). PMID- 29194585 TI - Complex interactions between hypoxia-ischemia and inflammation in preterm brain injury. AB - : Children surviving preterm birth have a high risk of disability, particularly cognitive and learning problems. There is extensive clinical and experimental evidence that disability is now primarily related to dysmaturation of white and gray matter, defined by failure of oligodendrocyte maturation and neuronal dendritic arborization, rather than cell death alone. The etiology of this dysmaturation is multifactorial, with contributions from hypoxia-ischemia, infection/inflammation and barotrauma. Intriguingly, these factors can interact to both increase and decrease damage. In this review we summarize preclinical and clinical evidence that all of these factors trigger secondary or chronic inflammation and gliosis. Thus, we hypothesize that these shared pathological features play a key role in a final common pathway that leads to the impaired neural maturation and connectivity and cognitive/motor impairments that are commonly observed in infants born preterm. This raises the possibility that secondary or chronic inflammation may be a viable therapeutic target for delayed interventions to improve neurodevelopmental outcomes after preterm birth. WHAT THIS PAPER ADDS: Hypoxia-ischemia, infection/inflammation, and barotrauma/volutrauma all contribute to preterm brain injury. Multiple different triggers of preterm brain injury are associated with central nervous system dysmaturation. Secondary brain inflammation may be a viable target to improve neurodevelopment after preterm birth. PMID- 29194587 TI - Genetic association of molecular traits: A help to identify causative variants in complex diseases. AB - In the past 15 years, major progresses have been made in the understanding of the genetic basis of regulation of gene expression. These new insights have revolutionized our approach to resolve the genetic variation underlying complex diseases. Gene transcript levels were the first expression phenotypes that were studied. They are heritable and therefore amenable to genome-wide association studies. The genetic variants that modulate them are called expression quantitative trait loci. Their study has been extended to other molecular quantitative trait loci (molQTLs) that regulate gene expression at the various levels, from chromatin state to cellular responses. Altogether, these studies have generated a wealth of basic information on the genome-wide patterns of gene expression and their inter-individual variation. Most importantly, molQTLs have become an invaluable asset in the genetic study of complex diseases. Although the identification of the disease-causing variants on the basis of their overlap with molQTLs requires caution, molQTLs can help to prioritize the relevant candidate gene(s) in the disease-associated regions and bring a functional interpretation of the associated variants, therefore, bridging the gap between genotypes and clinical phenotypes.

PMID- 29194589 TI - Pathological integration, or, how East Europeans use racism to become British. AB - East Europeans are integrating into life in the UK. This entails learning to get along with their new neighbours, but it also involves not getting along with certain neighbours. Integration is not confined to benevolent forms of everyday cosmopolitanism, multiculturalism and conviviality; it can also include more pathological forms, like racism. Whilst integration is generally seen as desirable, the learning that it entails necessarily includes less desirable practices and norms. The aim of this article is to show how East Europeans in the UK have been acquiring specifically British competencies of racism. This doesn't mean all East Europeans are racist or they always use racism; it does mean, however, that racism is a part of the integration equation. We focus on the racist and racializing practices of Poles, Hungarians and Romanians in Bristol in the UK. These East Europeans are using racism to insert themselves more favourably into Britain's racialized status hierarchies. This is a kind of integration. PMID- 29194590 TI - Effectiveness of Statins as Primary Prevention in People With Different Cardiovascular Risk: A Population-Based Cohort Study. AB - The purpose was to analyze statin effectiveness in a general population with differing levels of coronary heart disease (CHD) risk. Patients (35-74 years) without previous cardiovascular disease were included and stratified according to 10-year CHD risk (<5%, 5-7.4%, 7.5-9.9%, and 10-19.9%). New users were categorized according to their medical possession ratio (MPR). The main outcome was atherosclerotic cardiovascular disease (ASCVD) (myocardial infarction and ischemic stroke). In adherent patients (MPR 70%), statin treatment decreased ASCVD risk across the range of coronary risk (from 16-30%). The 5-year number needed to treat (NNT) was 470 and 204 in the risk categories <5% and 5-7.4%, respectively, and 75 and 62 in the 7.5-9.9% category than in the 10-19.9% category, respectively. Statin therapy should remain a priority in patients at high 10-year CHD risk (10-19.9%). Most patients with intermediate risk could benefit from statin treatment, but the treatment decision should focus on the net benefit, safety, and patient preference, given the higher NNT. PMID- 29194591 TI - A mutational comparison of adult and adolescent and young adult (AYA) colon cancer. AB - BACKGROUND: It is possible that the relative lack of progress in treatment outcomes among adolescent and young adult (AYA) patients with cancer is caused by a difference in disease biology compared with the corresponding diseases in younger and older individuals. There is evidence that colon cancer is more aggressive and has a poorer prognosis in AYA patients than in older adult patients. METHODS: To further understand the molecular basis for this difference, whole-exome sequencing was conducted on a cohort of 30 adult, 30 AYA, and 2 pediatric colon cancers. RESULTS: A statistically significant difference in mutational frequency was observed between AYA and adult samples in 43 genes, including ROBO1, MYC binding protein 2 (MYCBP2), breast cancer 2 (early onset) (BRCA2), MAP3K3, MCPH1, RASGRP3, PTCH1, RAD9B, CTNND1, ATM, NF1; KIT, PTEN, and FBXW7. Many of these mutations were nonsynonymous, missense, stop-gain, or frameshift mutations that were damaging. Next, RNA sequencing was performed on a subset of the samples to confirm the mutations identified by exome sequencing. This confirmation study verified the presence of a significantly greater frequency of damaging mutations in AYA compared with adult colon cancers for 5 of the 43 genes (MYCBP2, BRCA2, PHLPP1, TOPORS, and ATR). CONCLUSIONS: The current results provide the rationale for a more comprehensive study with a larger sample set and experimental validation of the functional impact of the identified variants along with their contribution to the biologic and clinical characteristics of AYA colon cancer.

AB - A new procedure was developed and applied to study immunoglobulin free light chains (FLC) in saliva of healthy subjects and patients with multiple sclerosis (MS). The procedure was based on a Western blot analysis for detection and semiquantitative evaluation of monomeric and dimeric FLCs. The FLC indices accounting for the total FLC levels and for the monomer/dimer ratios of kappa and lambda FLC were calculated, and the cut-off values of the FLC indices were determined to distinguish healthy state from MS disease. The obtained FLC index values were statistically different in the saliva of three groups: active MS patients, MS patients in remission and healthy subjects groups. Our FLC monomer dimer analysis allowed differentiation between healthy state and active MS with specificity of 100% and a sensitivity of 88.5%. The developed technique may serve as a new non-invasive complementary tool to evaluate the disease state by differentiating active MS from remission with sensitivity of 89% and specificity of 80%. PMID- 29194593 TI - JAK3 and PI3K mediate bovine Interferon-tau stimulated gene expression in the blood neutrophils. AB - Interferon tau, a 23 kDa trophoblast derived protein diffuses out from the uterus into the circulation and leads to the expression of IFNtau stimulated genes viz. ISG15 and OAS1 in blood neutrophils. The IFNtau pathway is species as well as tissue specific. To unsnarl the IFNtau downstream signaling pathway, the blood neutrophils were incubated simultaneously with 10 ng/ml of recombinant bovine interferon tau and the inhibitors of JAK2 (AG490), JAK3 (CP690550), p38 (SB202190), PI3K/Akt (LY294002), and MAPK/Erk (U0126) at specific doses for 4-hr duration. The IFNtau pathway was determined through real-time gene expression of ISG15 and OAS1; immunocytochemistry of ISG15; and Western blotting of ISG15, OAS1, pJAK3 and PI3K. The ISG15 and OAS1 expression decreased significantly (p < 0.001) in the presence of pJAK3 and PI3K inhibitors as compared to a positive control where only interferon tau was used. Immunocytochemistry revealed an attenuated ISG15 response while stimulating blood neutrophils with pJAK3 inhibitor (CP690550) and PI3K inhibitor (LY294002). Similarly, Western blot analysis of neutrophil protein fraction showed weak signals of ISG15, OAS1, pJAK3 and PI3K in the presence of pJAK3 and PI3K inhibitors. The expression profile, immunocytochemistry and western blot analysis revealed a JAK3 and PI3K mediated interferon-tau stimulated gene expression in blood neutrophils.

AB - OBJECTIVE: To develop a short-form Safety Net Medical Home Scale (SNMHS) for assessing patient-centered medical home (PCMH) capability in safety net clinics. DATA SOURCES/STUDY SETTING: National surveys of federally qualified health centers (FQHCs). Interviews with FQHC directors. STUDY DESIGN: We constructed three short-form SNMHS versions and examined correlations with full SNMHS and related primary care assessments. We tested usability with FQHC directors and reviewed scale development with an advisory group. DATA COLLECTION: Federally qualified health center surveys were administered in 2009 and 2013, by mail and online. Usability testing was conducted through telephone interviews with FQHC directors in 2013. PRINCIPAL FINDINGS: Six-, 12-, and 18-question short-form SNMHS versions had Pearson correlations with full scale of 0.84, 0.92, and 0.96, respectively. All versions showed a level of convergent validity with other primary care assessment scales comparable to the full SNMHS. User testers found short forms to be low-burden, though missing some PCMH concepts. Advisory group members expressed caution over missing concepts and appropriate use of short-form self-assessments. CONCLUSIONS: Short-form versions of SNMHS showed strong correlations with full scale and may be useful for brief assessment of safety net PCMH capability. Each short-form SNMHS version may be appropriate for different research, quality improvement, and assessment purposes.

PMID- 29194596 TI - Truncated isoform Vav3.1 is highly expressed in ovarian cancer stem cells and clinically relevant in predicting prognosis and platinum-response. AB - Vav3 is a key modulator of GTP-hydrolases of the Rho/Rac family, which are crucially involved in cell proliferation. Vav3 is alternatively spliced in full length Vav3-alpha and N-terminal truncated Vav3.1 lacking its self-regulatory domains. The aim of our study was to estimate the clinical impact of Vav3 and all other Vav family members in ovarian cancer. Purification of a stem-cell like side population (SP) from ovarian cancer cell lines was performed by flow cytometry/FACS. Differences in gene expression between SP and NSP were assessed by Gene Array analysis and confirmed by RT-PCR and immunoblot. In addition, Vav mRNA expression was determined in 150 epithelial ovarian cancers. Clinicopathological parameters, platinum-sensitivity and survival were analyzed and associated with Vav expression. SP fractions of ovarian cancer cell lines exhibited marked overexpression of Vav3.1 (p < 0.001). Vav1 and Vav2 did not prove to be of clinicopathologic relevance in ovarian cancer. High Vav3.1 expression correlated with higher FIGO stage and residual disease. Furthermore, Vav3.1 overexpression was associated with poor progression-free (HR = 2.820, p = 0.0001) and overall survival (HR = 2.842, p = 0.0001). Subgroup analyses revealed an impact of Vav3.1 on survival in Type-II but not in Type-I cancers. Notably, platinum-refractory cancers showed marked overexpression of Vav3.1 compared to other subsets of platinum-sensitivity (15.848 vs. 6.653, p = 0.0001). In conclusion, Vav3.1 is over-expressed in stem-cell like SP fractions and is clinically relevant in the pathophysiology of ovarian cancer. The N-terminal truncated Vav3.1 may be decisively involved in mechanisms causing genuine multi drug resistance. PMID- 29194598 TI - Composition, Granular Structure, and Pasting Properties of Native Starch Extracted from Plectranthus edulis (Oromo dinich) Tubers. AB - : Chemical composition, granular morphology and pasting properties of native starch extracted from tubers of Plectranthus edulis were analyzed. Starch was extracted from tubers of 6 accessions collected from 4 different areas in Ethiopia. Particle size analysis (PSA) and cryo-scanning electron microscope (cryo-SEM) imaging were used to examine the granular morphology and visualize the starch paste, respectively. Pasting properties, water absorption, and gelation capacity were compared. A wide range was found for the amylose (14.2% to 23.9%), calcium (216 to 599), potassium (131 to 878), and phosphorus (1337 to 2090) contents (parts per million per dry matter). PSA showed a bimodal distribution containing small spherical (14.6 MUm) and large ellipse-shaped (190.4 MUm) granules. Major differences were found for the pasting with peak viscosities differing from 3184 to 7312 mPa?s. Starch from accessions Chencha and Inuka showed a difference in packing density as clearly seen through cryo-SEM image at 75% of the peak viscosity (PV), and the granular integrity was mainly responsible for the significant difference in their PV and breakdown. Principal component analysis revealed 2 distinct groups: native starch extracted from accessions at the Wolayta zone (Inuka, Lofua, and Chenqoua) and other accessions (Jarmet, Arjo white, and Chencha). The study revealed the potential of P. edulis starch for its application in food industries. However, the inherent variation due to environmental conditions on physicochemical properties of the starch needs further investigation. PRACTICAL APPLICATION: Plectranthus edulis is cultivated in considerable amounts throughout Ethiopia, which makes it a valuable starch source. Due to its low tendency to retrograde, it could be applied in food industry as an equivalent for the current starch sources. Moreover, the low amylose content makes it preferable for an application in refrigerated foods as this unique quality trait prevents syneresis in end products during storage. Based on the significantly higher pasting temperature of the studied P. edulis starch extracts, it can form an alternative for potato starch, which is less suitable for its use in pasteurized foods. PMID- 29194599 TI - Teens and Spice: A Review of Adolescent Fatalities Associated with Synthetic Cannabinoid Use. AB - Synthetic cannabinoids (SCs) are commonly abused by adolescents with reported past year (2013) use in high school students between 3 and 10%. Standard adolescent postmortem toxicology does not include routine SC analysis, and thus, the true burden of fatalities related to SCs is unknown. A retrospective case review of two cases included scene investigation, interviews, autopsy, and toxicology. SCs were confirmed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Review of the eight adolescent SC-associated fatalities in the literature revealed five of eight cases had no other discernible cause of death on autopsy. Compounds detected included PB-22 (1.1 ng/mL), JWH-210 (12 ng/mL), XLR-11 (1.3 ng/mL), JWH-122, AB-CHMINACA (8.2 ng/mL), UR-144 (12.3 ng/mL), and JWH-022 (3 ng/mL). With synthetic drug use on the rise, forensic experts should have a high index of suspicion for the possibility of SC intoxication in adolescent fatalities with no other discernible cause of death. PMID- 29194600 TI - First record of non-native hybrid catfish Pseudoplatystoma reticulatum * Leiarius marmoratus in the Upper Parana River basin, Brazil. AB - The aim of this study is to report the presence of a three non-native hybrid long whiskered catfishes (family Pimelodidae) in the Upper Parana River basin, Brazil. Genetic analyses demonstrated that the three presumptive hybrids were a result of the crossbreeding of Pseudoplatystoma reticulatum (central Amazonas River basin and Lower Parana River) and Leiarius marmoratus (Amazonas, Essequibo and Orinoco rivers), producing a hybrid commonly known in Brazil as cachandia. The potential threat to biodiversity, due to possible genetic contamination, competition and predation of wild stocks, of such artificially produced hybrid fishes is discussed.

AB - PREMISE: Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri syndrome (PTC) is a serious neurological disorder that can lead to irreversible visual loss. Predominantly a disorder affecting women in reproductive years, the pediatric population is not spared. PROBLEM: In the past few years, the condition has been redefined, due to new accepted values for opening pressure in children and advances in neuroimaging. Emerging techniques in ophthalmology are being increasingly used to monitor disease in these patients. And, although the treatment tools have not changed in several years, important evidence for efficacy for acetazolamide finally came to light in recent years in the Idiopathic Intracranial Hypertension Treatment Trial (IIHTT). POTENTIAL SOLUTION: This review article provides an overview on recent advances in diagnosis, evaluation and treatment of IIH. PMID- 29194602 TI - Think before you leap. PMID- 29194603 TI - How to analyse the spatiotemporal tumour samples needed to investigate cancer evolution: A case study using paired primary and recurrent glioblastoma. AB - Many traits of cancer progression (e.g., development of metastases or resistance to therapy) are facilitated by tumour evolution: Darwinian selection of subclones with distinct genotypes or phenotypes that enable such progression. Characterising these subclones provide an opportunity to develop drugs to better target their specific properties but requires the accurate identification of somatic mutations shared across multiple spatiotemporal tumours from the same patient. Current best practices for calling somatic mutations are optimised for single samples, and risk being too conservative to identify shared mutations with low prevalence in some samples. We reasoned that datasets from multiple matched tumours can be used for mutual validation and thus propose an adapted two-stage approach: (1) low-stringency mutation calling to identify mutations shared across samples irrespective of the weight of evidence in a single sample; (2) high stringency mutation calling to further characterise mutations present in a single sample. We applied our approach to three-independent cohorts of paired primary and recurrent glioblastoma tumours, two of which have previously been analysed using existing approaches, and found that it significantly increased the amount of biologically relevant shared somatic mutations identified. We also found that duplicate removal was detrimental when identifying shared somatic mutations. Our approach is also applicable when multiple datasets e.g. DNA and RNA are available for the same tumour. PMID- 29194604 TI - Effects of microRNA-129 and its target gene c-Fos on proliferation and apoptosis of hippocampal neurons in rats with epilepsy via the MAPK signaling pathway. AB - This study aims to investigate the effect of microRNA-129 (miR-129) on proliferation and apoptosis of hippocampal neurons in epilepsy rats by targeting c-Fos via the MAPK signaling pathway. Thirty rats were equally classified into a model group (successfully established as chronic epilepsy models) and a normal group. Expression of miR-129, c-Fos, bax, and MAPK was detected by RT-qPCR and Western blotting. Hippocampal neurons were assigned into normal, blank, negative control (NC), miR-129 mimic, miR-129 inhibitor, siRNA-c-Fos, miR-129 inhibitor+siRNA-c-Fos groups. The targeting relationship between miR-129 and c Fos was predicted and verified by bioinformatics websites and dual-luciferase reporter gene assay. Cell proliferation after transfection was measured by MTT assay, and cell cycle and apoptosis by flow cytometry. c-Fos is a potential target gene of miR-129. Compared with the normal group, the other six groups showed a decreased miR-129 expression; increased expression of expression of c Fos, Bax, and MAPK; decreased proliferation; accelerated apoptosis; more cells arrested in the G1 phase; and fewer cells arrested in the S phase. Compared with the blank and NC groups, the miR-129 mimic group and the siRNA-c-Fos group showed decreased expression of c-Fos, Bax, and MAPK, increased cells proliferation, and decreased cell apoptosis, fewer cells arrested in the G1 phase and more cells arrested in the S phase. However, the miR-129 inhibitor groups showed reverse consequences. This study suggests that miR-129 could inhibit the occurrence and development of epilepsy by repressing c-Fos expression through inhibiting the MAPK signaling pathway. PMID- 29194605 TI - How the expression of green fluorescent protein and human cardiac actin in the heart influences cardiac function and aerobic performance in zebrafish Danio rerio. AB - The present study examined how the expression of enhanced green fluorescent protein (eGFP) and human cardiac actin (ACTC) in zebrafish Danio rerio influences embryonic heart rate (RH ) and the swim performance and metabolic rate of adult fish. Experiments with the adults involved determining the critical swimming speed (Ucrit , the highest speed sustainable and measure of aerobic capacity) while measuring oxygen consumption. Two different transgenic D. rerio lines were examined: one expressed eGFP in the heart (tg(cmlc:egfp)), while the second expressed ACTC in the heart and eGFP throughout the body (tg(cmlc:actc,ba:egfp)). It was found that RH was significantly lower in the tg(cmlc:actc,ba:egfp) embryos 4 days post-fertilization compared to wild-type (WT) and tg(cmlc:egfp). The swim experiments demonstrated that there was no significant difference in Ucrit between the transgenic lines and the wild-type fish, but metabolic rate and cost of transport (oxygen used to travel a set distance) was nearly two-fold higher in the tg(cmlc:actc,ba:egfp) fish compared to WT at their respective Ucrit . These results suggest that the expression of ACTC in the D. rerio heart and the expression of eGFP throughout the animal, alters cardiac function in the embryo and reduces the aerobic efficiency of the animal at high levels of activity. PMID- 29194606 TI - Induced mutation and epigenetics modification in plants for crop improvement by targeting CRISPR/Cas9 technology. AB - Clustered regularly interspaced palindromic repeats associated protein Cas9 (CRISPR-Cas9), originally an adaptive immunity system of prokaryotes, is revolutionizing genome editing technologies with minimal off-targets in the present era. The CRISPR/Cas9 is now highly emergent, advanced, and highly specific tool for genome engineering. The technology is widely used to animal and plant genomes to achieve desirable results. The present review will encompass how CRISPR-Cas9 is revealing its beneficial role in characterizing plant genetic functions, genomic rearrangement, how it advances the site-specific mutagenesis, and epigenetics modification in plants to improve the yield of field crops with minimal side-effects. The possible pitfalls of using and designing CRISPR-Cas9 for plant genome editing are also discussed for its more appropriate applications in plant biology. Therefore, CRISPR/Cas9 system has multiple benefits that mostly scientists select for genome editing in several biological systems. PMID- 29194607 TI - Contribution of Histidine and Lysine to the Generation of Volatile Compounds in Jinhua Ham Exposed to Ripening Conditions Via Maillard Reaction. AB - : To evaluate the role of Maillard reactions in the generation of flavor compounds in Jinhua ham, the reactions of glucose and ethanal with histidine and lysine, respectively, were studied by simulating the ripening conditions of Jinhua ham. The volatile products produced were analyzed using solid phase microextraction-gas chromatography/mass spectrometry. The results showed that 8 volatile compounds were generated by the reaction of glucose and histidine and 10 volatile compounds were generated by the reaction of glucose and lysine. Reactions of ethanal with lysine and with histidine both generated 31 volatile compounds that contributed to the flavor of Jinhua ham. This indicates that histidine and lysine related to Maillard reactions possibly play important roles in the generation of the unique flavor compounds in Jinhua ham. This research demonstrates that free amino acids participate in the generation of volatile compounds from Jinhua ham via the Maillard reaction and provides a basic mechanism to explain flavor formation in Jinhua ham. PRACTICAL APPLICATION: Jinhua ham is a well-known traditional Chinese dry-cured meat product. However, the formation of the compounds comprising its special flavor is not well understood. Our results indicate that Maillard reactions occur in Jinhua ham under ripening conditions. This work illustrates the contribution of Maillard reactions to the flavor of Jinhua ham. PMID- 29194608 TI - STR Genotyping from a Dry-Cleaned Skirt in a Sexual Assault Case. AB - In this sexual assault case, the standard preliminary semen examinations could not confirm physically or biochemically whether the accused's semen had stained the victim's skirt because the skirt had been dry-cleaned for stain removal and had been worn for more than a year after the assault. Fortunately, however, a photograph taken just after the assault was found in the court records that showed white stains on the checkered skirt. The locations of the stains were estimated based on the checkered pattern of the fabric, and microscopic examination using Baecchi's staining revealed the presence of spermatozoa. Further analysis indicated the male DNA profile generated from the sperm cells was consistent with the suspect's DNA using three multiplex STR typing systems for a total of 21 autosomal and 17 Y chromosomal short tandem repeats (STRs). Ultimately, the result of the DNA profile played a very useful role as additional evidence. PMID- 29194609 TI - Using the Connectivity Map to discover compounds influencing human osteoblast differentiation. AB - Osteoporosis is a common skeletal disorder characterized by low bone mass leading to increased bone fragility and fracture susceptibility. Identification of factors influencing osteoblast differentiation and bone formation is very important. Previously, we identified parbendazole to be a novel compound that stimulates osteogenic differentiation of human mesenchymal stromal cells (hMSCs), using gene expression profiling and bioinformatic analyzes, including the Connectivity Map (CMap), as an in-silico approach. The aim for this paper is to identify additional compounds affecting osteoblast differentiation using the CMap. Gene expression profiling was performed on hMSCs differentiated to osteoblasts using Illumina microarrays. Our osteoblast gene signature, the top regulated genes 6 hr after induction by dexamethasone, was uploaded into CMap (www.broadinstitute.org/cmap/). Through this approach we identified compounds with gene signatures positively correlating (withaferin-A, calcium folinate, amylocaine) or negatively correlating (salbutamol, metaraminol, diprophylline) to our osteoblast gene signature. All positively correlating compounds stimulated osteogenic differentiation, as indicated by increased mineralization compared to control treated cells. One of three negatively correlating compounds, salbutamol, inhibited dexamethasone-induced osteoblastic differentiation, while the other two had no effect. Based on gene expression data of withaferin-A and salbutamol, we identified HMOX1 and STC1 as being strongly differentially expressed . shRNA knockdown of HMOX1 or STC1 in hMSCs inhibited osteoblast differentiation. These results confirm that the CMap is a powerful approach to identify positively compounds that stimulate osteogenesis of hMSCs, and through this approach we can identify genes that play an important role in osteoblast differentiation and could be targets for novel bone anabolic therapies. PMID- 29194611 TI - TGFbeta signaling controls intrahepatic bile duct development may through regulating the Jagged1-Notch-Sox9 signaling axis. AB - Due to the inherent limitations of the mouse models, the molecular mechanism of TGFbeta signaling involved in the development of intrahepatic bile ducts (IHBDs) has been investigated little. Here, we investigated the role of TGFbeta signaling and its regulatory mechanism in IHBDs development. We demonstrate that TGFbeta signaling pathway activity is essential for IHBDs development. When blocking TGFbeta signaling at E10.5, the number of bile ducts in hilum was reduced more than two fold and number of CK19 positive chlangiocytes in periphery was reduced more than 3.5-fold compared with controls. We also show that alpha-smooth muscle actin (alpha-SMA)-immunoreactive cells are located in the portal vein mesenchyme (PVM) adjacent to the bile ducts during IHBDs development and identify the alpha SMA positive cells expressing the Notch ligand Jagged1 in the periportal area. Importantly, after blocking TGFbeta signaling, the expression of Jagged1 was selectively decreased in the PVM but not in biliary epithelial cells (BECs), which is associated with the transformation of portal mesenchyme cells (PMCs) into portal myofibroblasts (PMFs). In addition, Sox9, which is downstream of Notch, is decreased after blocking the TGFbeta signaling pathway in the liver. Our findings uncover a novel mechanism of TGFbeta signaling in controlling the development of IHBDs may through regulating the Jagged1-Notch-Sox9 signaling axis. PMID- 29194610 TI - Estimating the Cost Savings of Preventive Dental Services Delivered to Medicaid Enrolled Children in Six Southeastern States. AB - OBJECTIVE: To quantify the impact of multiyear utilization of preventive dental services on downstream dental care utilization and expenditures for children. DATA SOURCES/STUDY SETTING: We followed 0.93 million Medicaid-enrolled children who were 3-6 years old in 2005 from 2005 to 2011. We used Medicaid claims data of Alabama, Georgia, Mississippi, North Carolina, South Carolina, and Texas. STUDY DESIGN: We clustered each state's study population into four groups based on utilization of topical fluoride and dental sealants before caries-related treatment using machine learning algorithms. We evaluated utilization rates and expenditures across the four groups and quantified cost savings of preventive care for different levels of penetration. DATA EXTRACTION METHOD: We extracted all dental-related claims using CDT codes. PRINCIPAL FINDINGS: In all states, Medicaid expenditures were much lower for children who received topical fluoride and dental sealants before caries development than for all other children, with a per-member per-year difference ranging from $88 for Alabama to $156 for Mississippi. CONCLUSIONS: The cost savings from topical fluoride and sealants across the six states ranged from $1.1M/year in Mississippi to $12.9M/year in Texas at a 10 percent penetration level. Preventive dental care for children not only improves oral health outcomes but is also cost saving. PMID- 29194612 TI - Nanocurcumin restores aberrant miRNA expression profile in multiple sclerosis, randomized, double-blind, placebo-controlled trial. AB - In the current study, we aimed to identify nanocurcumin effects on microRNAs (miRNAs) in the peripheral blood of patients with relapsing-remitting multiple sclerosis (RRMS). We intended to investigate the expression pattern of these miRNAs in experimental settings in vivo. The expression levels of the selected 27 miRNAs known to be involved in the regulation of immune responses were analyzed in 50 RRMS patients and 35 healthy controls. The miRNA expression profiles were investigated by quantitative PCR (qPCR) at baseline and after 6 months of nanocurcumin therapy. Our data revealed that the expression of a number of microRNAs including miR-16, miR-17-92, miR-27, miR-29b, miR-126, miR-128, miR 132, miR-155, miR-326, miR-550, miR-15a, miR-19b, miR-106b, miR-320a, miR-363, miR-31, miR-150, and miR-340 is regulated by nanocurcumin. The results of the current work indicate that nanocurcumin is able to restore the expression pattern of dysregulated miRNAs in MS patients. We discovered that some miRNAs are deregulated in untreated patients compared with healthy controls and nanocurcumin treated patients. This is a new finding that might represent the potential contribution of these miRNAs to MS pathogenesis. Taken together, these data provide novel insights into miRNA-dependent regulation of the function of B and T cells in MS disease and enrich our understanding of the effects mediated by a therapeutic approach that targets B and T cells. PMID- 29194613 TI - Comparison of vegetable shortening and cocoa butter as vehicles for cortisol manipulation in Salmo trutta. AB - This study demonstrates that vegetable shortening and cocoa butter are two effective vehicles for intraperitoneal cortisol implants in juvenile teleosts, specifically brown trout Salmo trutta, residing in north temperate freshwater environments. Each vehicle showed a different pattern of cortisol elevation. Vegetable shortening was found to be a more suitable vehicle for long-term cortisol elevation [elevated at 3, 6 and 9 days post treatment (dpt)], while cocoa butter may be better suited for short-term cortisol elevation (only elevated at 3 dpt). Additionally, plasma cortisol levels were higher with cortisol-vegetable shortening than with cortisol-cocoa butter implants. Plasma glucose levels were elevated 6 and 9 dpt for fishes injected with cortisol vegetable shortening, but did not change relative to controls and shams in cortisol-cocoa butter fishes. In conclusion, vegetable shortening and cocoa butter are both viable techniques for cortisol manipulation in fishes in temperate climates, providing researchers with different options depending on study objectives. PMID- 29194614 TI - Immunomodulatory effects of foreskin mesenchymal stromal cells on natural killer cells. AB - Foreskin-mesenchymal stromal cells (FSK-MSCs) are immune-privileged thus making them valuable immunotherapeutic cell product. Characterization of the relationship between FSK-MSCs and natural killer (NK) cells is essential to improve cell-based therapy. In the present study, we studied for the first time FSK-MSCs-NK interaction and showed that the result of such cross talk was robustly dependent on the type of cytokines (IL-2, IL-12, IL-15, and IL-21) employed to activate NK cells. Distinctly activated-NK cells showed uneven cytotoxicity against FSK-MSCs, triggering their death in fine. The expression of different cell-surface ligands (CD112, CD155, ULPB-3) and receptors (LAIR, KIRs) ensuring such interaction was altered following co-culture of both populations. Despite their partial negative effect on NK cell proliferation, FSK-MSCs boosted the capacity of activated NK-cells to secrete IFN-gamma and TNF-alpha. Moreover, FSK-MSCs enhanced degranulation of NK cells, reinforced secretion of perforin and granzymes, while only modestly increased ROS production. On the other hand, FSK MSCs-mediated expression of C1 and B9 serpins was significantly lowered in the presence of activated NK cells. Altogether, our results highlight major immunological changes following FSK-MSCs-NK interaction. Understanding these outcomes will therefore enhance the value of the therapeutic strategy. PMID- 29194615 TI - The Impact of WIC on Infant Immunizations and Health Care Utilization. AB - OBJECTIVE: To test how prenatal participation in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) impacts health care utilization and immunizations within the first year of an infant's life. DATA SOURCE: We utilize comprehensive South Carolina Medicaid claims data from 2004 to 2013 linked with birth certificates data from 2004 to 2012. These data contain information on WIC participation and all health care utilization within the first year of an infant's life. STUDY DESIGN: We employ a maternal fixed-effects empirical design to control for unobserved factors that influence WIC participation and health care utilization. PRINCIPAL FINDINGS: We estimate that WIC participation increases infant health care utilization within the first year of life by 0.20 well-child visits (95 percent CI 0.16-0.23), by 0.22 vaccinations (95 percent CI 0.17-0.27), and by increasing the probability of receiving care in an emergency room by 2.9 percentage points (95 percent CI 2.0-3.8). Additionally, our results show that WIC participation decreases the average number of days an infant spends in the hospital within his or her first year of life by 0.41 days (95 percent CI 0.22-0.60). CONCLUSIONS: These findings suggest that WIC may increase health care costs in some dimensions while reducing it in others, and more work is needed to fully evaluate the impact of the program on future expenditures. PMID- 29194616 TI - Comparative analysis of single-cell RNA sequencing data from mouse spermatogonial and mesenchymal stem cells to identify differentially expressed genes and transcriptional regulators of germline cells. AB - Identifying effective internal factors for regulating germline commitment during development and for maintaining spermatogonial stem cells (SSCs) self-renewal is important to understand the molecular basis of spermatogenesis process, and to develop new protocols for the production of the germline cells from other cell sources. Therefore, this study was designed to investigate single-cell RNA sequencing data for identification of differentially expressed genes (DEGs) in 12 mouse-derived single SSCs (mSSCs) in compare with 16 mouse-derived single mesenchymal stem cells. We also aimed to find transcriptional regulators of DEGs. Collectively, 1,584 up-regulated DEGs were identified that are associated with 32 biological processes. Moreover, investigation of the expression profiles of genes including in spermatogenesis process revealed that Dazl, Ddx4, Sall4, Fkbp6, Tex15, Tex19.1, Rnf17, Piwil2, Taf7l, Zbtb16, and Cadm1 are presented in the first 30 up-regulated DEGs. We also found 12 basal transcription factors (TFs) and three sequence-specific TFs that control the expression of DEGs. Our findings also indicated that MEIS1, SMC3, TAF1, KAT2A, STAT3, GTF3C2, SIN3A, BDP1, PHC1, and EGR1 are the main central regulators of DEGs in mSSCs. In addition, we collectively detected two significant protein complexes in the protein-protein interactions network for DEGs regulators. Finally, this study introduces the major upstream kinases for the main central regulators of DEGs and the components of core protein complexes. In conclusion, this study provides a molecular blueprint to uncover the molecular mechanisms behind the biology of SSCs and offers a list of candidate factors for cell type conversion approaches and production of germ cells. PMID- 29194617 TI - A clinico-pathologic study of placenta percreta. AB - OBJECTIVE: To review a single-center case series of placenta percreta and to evaluate risk factors and the impact of surgical techniques used in previous cesarean delivery. METHODS: The present retrospective cohort study included pregnancies with placenta percreta managed between January 1, 2002, and March 31, 2017, at Saint Luc University Hospital, Brussels, Belgium. The data reviewed included demographics, outcomes, inter-pregnancy interval, and surgical techniques used for uterine closure in previous cesarean delivery. A cases series of non-accreta placenta previa was used as a control group. RESULTS: There were 19 pregnancies included in the study. The most common ultrasonography signs in the study group were loss of the clear zone (14/17; 82%), placental lacunae (17/17; 100%), and subplacental hypervascularity (11/14; 79%). Median gravidity, parity, and number of previous cesarean deliveries were higher (P<0.05) and inter pregnancy interval was longer (P<0.05) in the study group than the control group. There was no difference between the groups in the surgical techniques used for previous cesarean deliveries. CONCLUSION: The prenatal ultrasonography diagnosis of placenta percreta is accurate and facilitates optimal management by a specialized multidisciplinary team. Multicenter studies are required to further evaluate the impact of the surgical techniques used for prior cesarean delivery on the risks of placenta percreta in subsequent pregnancies. PMID- 29194618 TI - Narrower insight to SIRT1 role in cancer: A potential therapeutic target to control epithelial-mesenchymal transition in cancer cells. AB - The epithelial-mesenchymal transition (EMT) is a highly networked cellular process which involves cell transition from the immotile epithelial to the motile mesenchymal phenotype, whereby cells lose their cell-cell adhesion and cell polarity. This important process is one of the underlying mechanisms for enabling invasion and metastasis of cancer cells which is considered as malignant phase of tumor progression. However, the molecular mechanisms of this process are not fully clarified. It is reported that Sirtuin1 (SIRT1), a NAD+ dependent class III histone deacetylase is associated with tumor metastasis through positive regulation of EMT in several types of cancers. Recent studies confirmed that up and down regulation of SIRT1 expression remarkably change the migration ability of different cancer cells in vitro and tumor metastasis in vivo. Also, according to this fact that carcinomas as the main human solid tumors, originate from different epithelial cell types, SIRT1 role in EMT has received a great attention due to its potential role in tumor development and metastasis. Therefore, SIRT1 has been proposed as a key regulator of cancer metastasis by promoting EMT, although little is known about the cleared effect of SIRT1 in this transition. Our aim in this review is to explain in more detail the role of SIRT1 in various signaling pathways related to carcinogenesis, with the focus on the promoting role of SIRT1 in EMT as a potential therapeutic target to control EMT and to prevent cancer progression. PMID- 29194619 TI - Direct Conservative Domain in the Continuous Galerkin Method for Groundwater Models. AB - The continuous Galerkin finite element method is commonly considered locally nonconservative because a single element with fluxes computed directly from its potential distribution is unable to conserve its mass and fluxes across edges that are discontinuous. Some literature sources have demonstrated that the continuous Galerkin method can be locally conservative with postprocessed fluxes. This paper proposes the concept of a direct conservative domain (DCD), which could conserve mass when fluxes are computed directly from the potential distribution. Also presented here is a method for modifying the advection fluxes to obtain different conservative domains from the DCDs. Furthermore, DCDs are used to analyze the local conservation of several postprocessing algorithms, for which DCDs provide the theoretical basis. The local conservation of DCDs and the proposed method are illustrated and verified by using a hypothetical 2-D model. PMID- 29194620 TI - Pharmacogenetics: A strategy for personalized medicine for autoimmune diseases. AB - For many years, a considerable number of patients with autoimmune diseases (ADs) have suffered from a lack of drug response and drug-related toxicity. Despite the emergence of new therapeutic options such as biological agents, patients continue to struggle with these problems. Unfortunately, new challenges, including the paradoxical effects of biological drugs, have complicated the situation. In recent decades, efforts have been made to predict drug response as well as drug related side effects. Thanks to the many advances in genetics, evaluation of markers to predict drug response/toxicity before the initiation of treatment may be an avenue toward personalizing treatments. Implementing pharmacogenetics and pharmacogenomics in the clinic could improve clinical care; however, obstacles remain to effective personalized medicine for ADs. The present study attempted to clarify the concept of pharmacogenetics/pharmacogenomics for ADs. After an overview on the pathogenesis of the most common types of treatments, this paper focuses on pharmacogenetic studies related to the selected ADs. Bridging the gap between pharmacogenetics and personalized medicine is also discussed. Moreover, the advantages, disadvantages and recommendations related to making personalized medicine practical for ADs have been addressed. PMID- 29194621 TI - Effects of the Medicare Modernization Act on Spending for Outpatient Surgery. AB - OBJECTIVES: To examine the effects of Medicare's revised ambulatory surgery center (ASC) payment schedule on overall payments for outpatient surgery. DATA SOURCES: Twenty percent sample of national Medicare beneficiaries. STUDY DESIGN: We conducted a pre-post study of Medicare beneficiaries who underwent outpatient surgery in a hospital outpatient department (HOPD), ASC, or physician office between 2004 and 2011. Specifically, we used multivariable regression to compare temporal trends in outpatient surgery before and after implementation of Medicare's revised payment schedule in 2008, which reduced ASC facility payments to roughly two-thirds that of HOPDs. Our outcome measures included overall Medicare payments, utilization rates, per beneficiary spending, and average episode payments for outpatient surgery. PRINCIPAL FINDINGS: Between the last quarters of 2007 and 2008, overall Medicare payments for outpatient surgery grew by $334 million-an amount nearly three times higher than would have been expected without the policy change (p < .001 for the difference). While utilization rates of outpatient surgery were attenuated, per beneficiary spending and average surgical episode payments increased by 10.4 percent and 7.8 percent, respectively, over the same period. By the end of 2011, Medicare payments for outpatient surgery reached $5.1 billion. Without the policy change, they would have totaled only $4.1 billion. CONCLUSIONS: Despite lessening demand, reduced ASC facility payments did not curb spending for outpatient surgery. In fact, overall payments actually increased following the policy change, driven by higher average episode payments. PMID- 29194622 TI - Ceratocorys mariaovidiorum sp. nov. (Gonyaulacales), a new dinoflagellate species previously reported as Protoceratium reticulatum. AB - The family Ceratocoryaceae includes the genera Ceratocorys, Protoceratium, and Schuettiella, whose phylogenetic relationships are poorly known. Here, the new non-yessotoxin-producing species of the genus Ceratocorys, Ceratocorys mariaovidiorum sp. nov., previously reported as the toxic Protoceratium reticulatum, is described from examinations by light and scanning electron microscopy, molecular phylogeny, and toxin analyses. The species description is made from culture samples of strains CCMP1740 and CCMP404 from USA waters. Ceratocorys mariaovidiorum is globular and has thick and strongly reticulated plates with one pore within each reticule, just like P. reticulatum, but the key difference between the two species is the presence of five precingular plates in C. mariaovidiorum instead of six as in P. reticulatum. The thecal plate formula is Po, 4', 0a, 5", 6c, ~7s, 5''', 0p, 2''''. The apical pore plate is oval with a lambda-shaped pore. The first apical plate is narrow with a ventral pore on the right anterior side; it contacts the apical pore plate and its contact with the anterior sulcal plate is slight or absent. The fourth precingular plate of other Gonyaulacales is absent. Ceratocorys mariaovidiorum may have small spines on the second antapical plate. A phylogenetic study based on internal transcribed spacer/5.8SrDNA supports the morphological classification of C. mariaovidiorum as a new species of Ceratocorys and in a different clade from P. reticulatum. PMID- 29194623 TI - Phase II trial of preoperative chemoradiation plus perioperative SOX chemotherapy in patients with locally advanced gastric cancer. AB - BACKGROUND AND PURPOSE: The ideal treatment strategy of patients with locally advanced gastric adenocarcinoma is unclear. The aim of this study is to evaluate the efficacy and feasibility of preoperative chemoradiation in these patients. PATIENTS AND METHODS: All patients underwent laparoscopic exploration or exploratory laparotomy before chemoradiation. Patients received one cycle of S-1 and oxalipatin followed by concurrent radiation and chemotherapy, then underwent another cycle of S-1 and oxalipatin. Surgery was performed 6-8 weeks after completing radiochemotherapy. The rate of curative gastrectomy and survival were investigated. This trial was registered with ClinicalTrial.gov, number NCT02024217. RESULTS: From April 2012 to August 2014, 40 patients were enrolled in the trial, and 36 patients were assessable. The most common hematologic toxic effects were leukopenia (80.6%), neutropenia (69.4%), and thrombocytopenia (50%); the most common nonhematologic toxic effects were anorexia (50%), nausea (22.3%), and vomiting (13.9%). There were no treatment related deaths. A total of 33 patients underwent second exploratory laparotomy after preoperative chemoradiation, and 24 (67%) patients received curative gastrectomy. The rates of pathological complete response (pCR) were 13.9%. The medial survival time (MST) was 30.3 months. CONCLUSION: Preoperative chemoradiation may be an effective treatment strategy among patients with locally advanced gastric adenocarcinoma. PMID- 29194624 TI - A Three-Locus, PCR-based Method for Forensic Identification of Plant Material. AB - Plant residue is currently an underutilized resource in forensic investigations despite the fact that many crime scenes, as well as suspects and victims, harbor plant-derived residue that could be recovered and analyzed. Notwithstanding the considerable skill of forensic botanists, current methods of species determination could benefit from tools for DNA-based species identification. However, DNA barcoding in plants has been hampered by sequence complications in the plant genome. Following a database search for usable barcodes, broad-spectrum primers were designed and utilized to amplify and sequence the rbcL, trnL-F, and rrn18 genetic loci from a variety of household plants. Once obtained, these DNA sequences were used to design species-targeted primers that could successfully discriminate the source of plant residue from among the 21 species tested. PMID- 29194625 TI - Laryngeal chondronecrosis after radiation therapy in a dog. AB - A 5-year-old pug presented with a soft tissue swelling on the ventral neck and moderate stridor with associated respiratory effort. This patient received hypofractionated radiotherapy for metastatic upper lip mast cell tumour and to the submandibular lymph nodes 6 months before presentation. Oral examination showed moderate elongation of the soft palate, stage III laryngeal collapse with only the right laryngeal saccule mildly everted and exuberant pale epiglottal and left pharyngeal mucosa. Staphylectomy, resection of the epiglottal mucosa and left arytenoid lateralisation were performed. One day after surgery, temporary tracheostomy was performed after respiratory distress due to the severe laryngeal and pharyngeal oedema. A third oral exam showed pale and redundant caudal pharyngeal mucosa obstructing the rima glottis, soft and collapsible arytenoid cartilage with pale mucosa and bilateral everted laryngeal saccules. Permanent tracheostomy was elected and laryngeal cartilage biopsies were taken. Histologic diagnosis showed cartilage necrosis and abundant tissue oedema. The patient was euthanased 1 week later.

Reconstitution of the ubiquitination cascade in bacterial systems circumvents several of these problems and was shown to faithfully recapitulate the process. Here, we present UbiGate - a synthetic biology toolbox, together with an inducible bacterial expression system - to enable the straightforward reconstitution of the ubiquitination cascades of different organisms in Escherichia coli by 'Golden Gate' cloning. This inclusive toolbox uses a hierarchical modular cloning system to assemble complex DNA molecules encoding the multiple genetic elements of the ubiquitination cascade in a predefined order, to generate polycistronic operons for expression. We demonstrate the efficiency of UbiGate in generating a variety of expression elements to reconstitute autoubiquitination by different E3 ligases and the modification of their substrates, as well as its usefulness for dissecting the process in a time- and cost-effective manner.

AB - KEY POINTS: Bassoon and Piccolo do not mediate basal synaptic vesicle release at a high-frequency synapse. Knockdown of Bassoon increases short-term depression at the calyx of Held. Both Bassoon and Piccolo have shared functions in synaptic vesicle replenishment during high-frequency synaptic transmission. Piccolo organizes the readily releasable pool of synaptic vesicles. It safeguards a fraction of them to be not immediately available for action potential-induced release. This enables the synapse to sustain high-frequency synaptic transmission over long periods. ABSTRACT: Synaptic vesicles (SVs) are released at the active zone (AZ), a specialized region of the presynaptic plasma membrane organized by a highly interconnected network of multidomain proteins called the cytomatrix of the active zone (CAZ). Two core components of the CAZ are the large, highly homologous scaffolding proteins Bassoon and Piccolo, whose function is not well understood. To investigate their role in synaptic transmission, we established the small hairpin RNA (shRNA)-mediated in vivo knockdown (KD) of Bassoon and Piccolo at the rat calyx of Held synapse. KD of Bassoon and Piccolo, separately or simultaneously, did not affect basic SV release. However, short-term depression (STD) was prominently increased by the KD of Bassoon, whereas KD of Piccolo only had a minor effect. The observed alterations in STD were readily explained by reduced SV replenishment in synapses deficient in either of the proteins. Thus, the regulation of SV refilling during ongoing synaptic activity is a shared function of Bassoon and Piccolo, although Bassoon appears to be more efficient. Moreover, we observed the recruitment of slowly-releasing SVs of the readily-releasable pool (RRP), which are normally not available for action potential-induced release, during high-frequency stimulation in Piccolo-deficient calyces. Therefore, the results obtained in the present study suggest a novel and specific role for Piccolo in the organization of the subpools of the RRP.

AB - Retroperitoneal sarcomas (RPS) frequently involve major vessels, which either originate from them or secondarily encase or invade them. In this field, major vascular resections result in increased morbidity. However, survival does not seem to be affected by the need for vascular resection or by this higher morbidity. This paper aims to provide descriptions of the surgical strategy and outcomes for retroperitoneal sarcomas involving major vessels. PMID- 29194631 TI - Rapid authentication of edible bird's nest by FTIR spectroscopy combined with chemometrics. AB - BACKGROUND: Edible bird's nests (EBNs) have been traditionally regarded as a kind of medicinal and healthy food in China. For economic reasons, they are frequently subjected to adulteration with some cheaper substitutes, such as Tremella fungus, agar, fried pigskin, and egg white. As a kind of precious and functional product, it is necessary to establish a robust method for the rapid authentication of EBNs with small amounts of samples by simple processes. In this study, the Fourier transform infrared spectroscopy (FTIR) system was utilized and its feasibility for identification of EBNs was verified. RESULTS: FTIR spectra data of authentic and adulterated EBNs were analyzed by chemometrics analyses including principal component analysis, linear discriminant analysis (LDA), support vector machine (SVM) and one-class partial least squares (OCPLS). The results showed that the established LDA and SVM models performed well and had satisfactory classification ability, with the former 94.12% and the latter 100%. The OCPLS model was developed with prediction sensitivity of 0.937 and specificity of 0.886. Further detection of commercial EBN samples confirmed these results. CONCLUSION: FTIR is applicable in the scene of rapid authentication of EBNs, especially for quality supervision departments, entry-exit inspection and quarantine, and customs administration.

AB - Piezo1 channels are newly discovered ion channels which have come to the fore as players in endothelial biology. They have a key role as sensors of shear stress, a frictional force which arises in vascular biology because of blood flow. Endothelial Piezo1 channels are critical in murine embryonic development, just after the heart starts to beat and drive blood into the nascent endothelial network. In contrast they are not critical at the adult stage but they are important for performance in whole body physical activity where they have a vascular bed-specific effect to cause mesenteric resistance artery vasoconstriction, achieved through opposition to the vasodilatory mechanism of endothelium-derived hyperpolarization. These are our first insights into the relevance of endothelial Piezo1 channels and there is clearly much more to be done to understand the significance and underlying molecular mechanisms. The suggestion that they constitute an exercise sensor by virtue of their shear stress-sensing capability is intriguing and could open the way to better understanding of the molecular basis of the response to exercise and determination of how the health benefits of exercise arise. Enhanced Piezo1 channel activity has been demonstrated in response to the Yoda1 molecule and this suggests the possibility for developing tools which probe and manipulate this aspect of the exercise system. Whether such agents might progress to 'exercise pills' and whether the existence of such pills would be desirable are matters for further work and debate.

The type of systemic therapy used is guided by the histological subtype. The majority of retroperitoneal sarcomas comprising liposarcomas and leiomyosarcomas are by and large chemotherapy insensitive. There is an urgent need for more efficacious systemic therapies in the management of early and advanced stage retroperitoneal sarcomas.

Future perspectives: towards the next level of the Ub code 1006 Acknowledgements 1006 References 1007 SUMMARY: Ubiquitination is a post translational modification essential for the regulation of eukaryotic proteins, having an impact on protein fate, function, localization or activity. What originally appeared to be a simple system to regulate protein turnover by the 26S proteasome is now known to be the most intricate regulatory process cells have evolved. Ubiquitin can be arranged in countless chain assemblies, triggering various cellular outcomes. Polyubiquitin chains using lysine-63 from ubiquitin represent the second most abundant type of ubiquitin modification. Recent studies have exposed their common function in proteasome-independent functions in non plant model organisms. The existence of lysine-63 polyubiquitination in plants is, however, only just emerging. In this review, we discuss the recent advances on the characterization of ubiquitin chains and the molecular mechanisms driving the formation of lysine-63-linked ubiquitin modifications. We provide an overview of the roles associated with lysine-63 polyubiquitination in plant cells in the light of what is known in non-plant models. Finally, we review the crucial roles of lysine-63 polyubiquitin-dependent processes in plant growth, development and responses to environmental conditions. PMID- 29194635 TI - OsCERK1 plays a crucial role in the lipopolysaccharide-induced immune response of rice. AB - Plant cell surface receptor-like kinases (RLKs) mediate the signals from microbe associated molecular patterns (MAMPs) that induce immune responses. Lipopolysaccharide (LPS), the major constituent of the outer membrane of gram negative bacteria, is a common MAMP perceived by animals and plants; however, the plant receptors/co-receptors are unknown except for LORE, a bulb-type lectin S domain RLK (B-lectin SD1-RLK) in Arabidopsis. OsCERK1 is a multifunctional RLK in rice that contains lysin motifs (LysMs) and is essential for the perception of chitin, a fungal MAMP, and peptidoglycan, a bacterial MAMP. Here, we analyzed the relevance of OsCERK1 to LPS perception in rice. Using OsCERK1-knockout mutants (oscerk1), we evaluated hydrogen peroxide (H2 O2 ) production and gene expression after LPS treatment. We also examined the LPS response in knockout mutants for the B-lectin SD1-RLK genes in rice and for all LysM-protein genes in Arabidopsis. Compared with wild-type rice cells, LPS responses in oscerk1 cells were mostly diminished. By contrast, rice lines mutated in either of three B-lectin SD1-RLK genes and Arabidopsis lines mutated in the LysM-protein genes responded normally to LPS. From these results, we conclude that OsCERK1 is an LPS receptor/co receptor and that the LPS perception systems of rice and Arabidopsis are significantly different. PMID- 29194636 TI - Benthic flattened cells of the phylogenetically related marine dinoflagellates Protoceratium reticulatum and Ceratocorys mariaovidiorum (Gonyaulacales): a new type of cyst? AB - A planktonic-benthic relationship has been described for many dinoflagellate species as part of their ecological strategy to overcome highly variable aquatic environments. Here, the phylogenetically and morphologically related marine dinoflagellates Protoceratium reticulatum and Ceratocorys mariaovidiorum were studied in relation to an unknown benthic life form. In vivo and fixed samples from cultures were analyzed in detail by light and scanning electron microscopy. In both species, a cell type with a morphology different from that of vegetative cells was observed in cultures grown until stationary phase. This cell type was always benthic, swimming sporadically only when it was disturbed. Its main feature included a strong dorsoventral compression. These cells originated from vegetative cells whose protoplasm underwent a progressive flattening, resulting in a gradual detachment of the reticulate and thick thecal plates and the formation of very thin non-reticulated new plates with pores. When returned to fresh full-strength medium, the cells recovered their spherical vegetative-like morphology, including new reticulated thick plates and subsequent cell divisions. The kinetics of flattened cell formation showed that in both species, this cell type increased exponentially until the onset of the culture stationary phase and then decreased. The results of this study are discussed in the context of the planktonic-benthic coupling in dinoflagellate life cycles, including those newly appreciated to be well adapted to the benthic environment. PMID- 29194638 TI - Divided stimulus control: Which key did you peck, or what color was it? AB - Responding on concurrent schedules produced a conditional discrimination (Phases 1 and 2), asking either which peck produced the event, or which color the keys were when the event was produced. In Phases 3 and 4, reinforcer delivery or a delay in blackout was interpolated between responding and the conditional discrimination. In Phase 1, location versus color discrimination accuracy was controlled by the relative reinforcer frequency for correct responses to these questions (divided stimulus control). In Phases 2 to 4, relative reinforcer frequency for correct responses to these questions was .5, and the relative frequency with which concurrent-schedule responses produced the questions was varied. This variation had no clear effect on the accuracy of reporting Location or Color. These results are consistent with the model of divided control suggested by Davison and Elliffe (2010). Arranging a 3-s reinforcer between responding and choice decreased both color and location accuracy, but a 3-s delay only decreased location accuracy. Thus, in concurrent-schedule performance, both ambient stimuli prior to a reinforcer and the location of the just-reinforced response are available as discriminative stimuli following the reinforcer. Control of postreinforcer responding is divided between these according to their association with the relative frequency of subsequent reinforcers.

AB - BACKGROUND: Recent epidemiological studies have suggested that phenolic compounds present in grapefruit play an important role in the bioactive properties of this fruit. However, the consumption of fresh grapefruit is low. Freeze-dried powdered grapefruit can be an alternative to promote this fruit consumption. To improve the quality and stability of the powdered fruit, encapsulating and anticaking agents can be added. In the present study, different grapefruit powders obtained by freeze-drying with the addition of gum arabic (1.27 g per 100 g) and bamboo fibre (0.76 g per 100 g) with and without a pre-drying microwave treatment were compared with the fresh and freeze-dried fruit with no carriers added, aiming to evaluate the effect of these preservation processes on phenolics content and on its antioxidant [1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azinobis(3 ethylbenzothiazoline-6-sulphonic acid) (ABTS) and ferric reducing ability of plasma (FRAP)] and anti-inflamatory (evaluated in RAW 264.7 macrophages) capacities. RESULTS: Freeze-drying and gum arabic and bamboo fibre addition significantly increased total phenolics, as well as the antioxidant and anti inflammatory activities (by inhibiting nitric oxide production of lipopolysaccharide activated RAW 264.7 macrophages), of grapefruit. An additional increase in these parameters was obtained with microwave pretreatment before freeze-drying. CONCLUSIONS: The combined addition of gum arabic and bamboo fibre to grapefruit puree and the application of a microwave pretreatment improve the functional properties of the fruit without showing cytotoxicity in vitro.

AB - BACKGROUND: Shalgam is a traditional lactic acid fermented beverage highly popular in southern Turkey. The main raw material, black carrot, contains a significant amount of anthocyanins. In this study, changes in polyphenols, including anthocyanins, related total antioxidant capacity (TAC), and in vitro bioaccessibility during shalgam fermentation and main raw material were evaluated. RESULTS: Compared with the last 12 days of the fermentation, a higher increase in total phenolic content (TPC), anthocyanins content (AC), and TAC was observed in the first 12 days of the fermentation during shalgam production. Although black carrot exhibited the highest total flavonoid content (TFC), TPC, AC, and TAC values before bioaccessibility tests, the recovery of shalgam beverage was found to be mostly identical with black carrot results in terms of flavonoids, phenolics, and anthocyanins and antioxidant capacity after in vitro digestion. In vitro digestion significantly reduced the recovery of initial samples in terms of TFC, TPC, AC, and TAC analysis. The amount of beneficial compound in the early fermentation stage was significantly lower than with end product. Sixteen different phenolics were detected from shalgam beverage samples in high-performance liquid chromatography analysis. After performing bioaccessibility tests, only five phenolics were detected. As anthocyanins, only cyanidin content was identified. CONCLUSION: The degradation of phenolics and anthocyanins was observed after bioaccessibility tests. (c) 2017 Society of Chemical Industry. PMID- 29194640 TI - The Microvine, a plant model to study the effect of vine-shoot extract on the accumulation of glycosylated aroma precursors in grapes. AB - BACKGROUND: The Microvine plant model displays unique reproductive organ behavior and is suitable for grapevine fruit physiological studies, allowing one to undertake studies up to five times more rapidly than the current situation with grapevines. Recently, vine-shoot aqueous extracts, which have an interesting phenolic and aroma composition, have been proposed as viticultural biostimulants, since their post-veraison foliar application to grapevines impacts the wine aroma profile. Using Microvines, the aim of this study was to determine the effect of vine-shoot extract foliar application on 21 stages of grape development. The application was carried out from BBCH 53 (inflorescences clearly visible) to BBCH 85 (softening of berries) to reveal stage-specific responses of the accumulation of glycosylated aroma precursors at BBCH 89 (berries ripe for harvest), the phenological stage selected to study the treatment effect. RESULTS: Microvine use made it possible to carry out 15 sampling time points during 86 days of the experiment, which were established by the cumulative degree days (CDD) parameter. The results confirmed that vine-shoot extract treatment had a positive impact on total glycosylated compounds, especially aglycones such as alcohols, terpenes and C13 -norisoprenoids, with a higher effect when the treatment was applied during ripening. CONCLUSION: Extrapolation of the results to grapevines suggests that vine-shoot extract treatment could modulate the synthesis of grape glycosylated aroma precursors.

AB - BACKGROUND: Numerous studies indicate mineral deficiencies in people on a gluten free (GF) diet. These deficiencies may indicate that GF products are a less valuable source of minerals than gluten-containing products. In the study, the nutritional quality of 50 GF products is discussed taking into account the nutritional requirements for minerals expressed as percentage of recommended daily allowance (%RDA) or percentage of adequate intake (%AI) for a model celiac patient. Elements analyzed were calcium, potassium, magnesium, sodium, copper, iron, manganese, and zinc. Analysis of %RDA or %AI was performed using principal component analysis (PCA) and hierarchical cluster analysis (HCA). RESULTS: Using PCA, the differentiation between products based on rice, corn, potato, GF wheat starch and based on buckwheat, chickpea, millet, oats, amaranth, teff, quinoa, chestnut, and acorn was possible. In the HCA, four clusters were created. The main criterion determining the adherence of the sample to the cluster was the content of all minerals included to HCA (K, Mg, Cu, Fe, Mn); however, only the Mn content differentiated four formed groups. CONCLUSION: GF products made of buckwheat, chickpea, millet, oats, amaranth, teff, quinoa, chestnut, and acorn are better source of minerals than based on other GF raw materials, what was confirmed by PCA and HCA.

AB - BACKGROUND: The ability of Antarctic krill, Euphausia superba (Dana, 1852), to thrive in a cold environment comes from its capacity to synthesize cold-adapted enzymes. Its trypsin, as a main substance in the metabolic reactions, plays a key role in the adaption to low temperatures. However, the progress of research on its cold-adaption mechanism is being influenced due to the limited information on its gene and spatial structure. RESULTS: We studied the gene of E. superba trypsin with transcriptome sequencing first, and then discussed its cold-adaption mechanism with the full gene and predicted structure basing on bioinformatics. The results showed the proportion of certain residues played important roles in the cold-adaptation behavior for trypsin. Furthermore, a higher proportion of random coils and reduced steric hindrance might also be key factors promoting its cold adaption. CONCLUSION: This research aimed to reveal the cold-adaption mechanism of E. superba trypsin and provide support for basic research on molecular modification by site-directed mutagenesis of complementary DNA used to produce new and improved recombinant variants with cold adaption. Furthermore, it may broaden its commercial application on minimizing undesirable changes elevated at higher temperature in food processing and in treatment of trauma and inflammation in medicine.

AB - Much of our current knowledge of microbial growth is obtained from studies at a population level. Driven by the realization that processes that operate within a population might influence a population's behavior, we sought to better understand Tetradesmus obliquus (formerly Scenedesmus obliquus) physiology at the cellular level. In this work, an accurate pretreatment method to quantitatively obtain single cells of T. obliquus, a coenobia-forming alga, is described. These single cells were examined by flow cytometry for triacylglycerol (TAG), chlorophyll, and protein content, and their cell sizes were recorded by coulter counter. We quantified heterogeneity of size and TAG content at single-cell level for a population of T. obliquus during a controlled standard batch cultivation. Unexpectedly, variability of TAG content per cell within the population increased throughout the batch run, up to 400 times in the final stage of the batch run, with values ranging from 0.25 to 99 pg . cell-1 . Two subpopulations, classified as having low or high TAG content per cell, were identified. Cell size also increased during batch growth with average values from 36 to 70 MUm3 . cell-1 ; yet cell size variability increased only up to 16 times. Cell size and cellular TAG content were not correlated at the single-cell level. Our data show clearly that TAG production is affected by cell-to-cell variation, which suggests that its control and better understanding of the underlying processes may improve the productivity of T. obliquus for industrial processes such as biodiesel production. PMID- 29194644 TI - Independent signalling cues underpin arbuscular mycorrhizal symbiosis and large lateral root induction in rice. AB - Perception of arbuscular mycorrhizal fungi (AMF) triggers distinct plant signalling responses for parallel establishment of symbiosis and induction of lateral root formation. Rice receptor kinase CHITIN ELICITOR RECEPTOR KINASE 1 (CERK1) and alpha/beta-fold hydrolase DWARF14-LIKE (D14L) are involved in pre symbiotic fungal perception. After 6 wk post-inoculation with Rhizophagus irregularis, root developmental responses, fungal colonization and transcriptional responses were monitored in two independent cerk1 null mutants; a deletion mutant lacking D14L, and with D14L complemented as well as their respective wild-type cultivars (cv Nipponbare and Nihonmasari). Here we show that although essential for symbiosis, D14L is dispensable for AMF-induced root architectural modulation, which conversely relies on CERK1. Our results demonstrate uncoupling of symbiosis and the symbiotic root developmental signalling during pre-symbiosis with CERK1 required for AMF-induced root architectural changes. PMID- 29194645 TI - Detection and Identification of Psilocybe cubensis DNA Using a Real-Time Polymerase Chain Reaction High Resolution Melt Assay. AB - Psilocybe cubensis, or "magic mushroom," is the most common species of fungus with psychedelic characteristics. Two primer sets were designed to target Psilocybe DNA using web-based software and NBCI gene sequences. DNA was extracted from eighteen samples, including twelve mushroom species, using the Qiagen DNeasy(r) Plant Mini Kit. The DNA was amplified by the polymerase chain reaction (PCR) using the primers and a master mix containing either a SYBR(r) Green I, RadiantTM Green, or LCGreen Plus(r) intercalating dye; amplicon size was determined using agarose gel electrophoresis. The PCR assays were tested for amplifiability, specificity, reproducibility, robustness, sensitivity, and multiplexing with primers that target marijuana. The observed high resolution melt (HRM) temperatures for primer sets 1 and 7 were 78.85 +/- 0.31 degrees C and 73.22 +/- 0.61 degrees C, respectively, using SYBR(r) Green I dye and 81.67 +/- 0.06 degrees C and 76.04 +/- 0.11 degrees C, respectively, using RadiantTM Green dye. PMID- 29194646 TI - Conservative management of placenta percreta. AB - BACKGROUND: Maternal outcomes after conservative management of placenta percreta are poorly understood. OBJECTIVE: To assess the success and complication rates of conservative management of placenta percreta. SEARCH STRATEGY: The PubMed, MEDLINE, and Scopus databases were searched for English-language articles published between January 1990 and December 2016, using combinations of search terms related to conservative management of placenta percreta. SELECTION CRITERIA: Only studies describing conservative treatment for placenta percreta (without placental removal) were included in the systematic review. DATA COLLECTION AND ANALYSIS: There were 44 studies included and maternal outcomes were reviewed and categorized among 72 patients. MAIN RESULTS: The uterus was preserved among 42 (58%) patients and severe complications developed among 40 (56%). Prophylactic uterine artery embolization (UAE) did not improve success rates (P=0.807); however, the mean time for complete placental resorption was lower in the UAE group than in the non-UAE group (22.4 weeks vs 35.3 weeks; P=0.014). Hysterectomy was performed at a mean of 44.6 days after cesarean delivery. Among the 23 patients with hysterectomy-related complications, 18 (78%) experienced bladder injury, intraoperative bleeding (>2000 mL), or both. The use of chemotherapy did not improve success rates (P=0.064). CONCLUSIONS: The present systematic review revealed high maternal morbidity during conservative management of placenta percreta. PMID- 29194647 TI - The RAS mutation status predicts survival in patients undergoing hepatic resection for colorectal liver metastases: The results from a genetic analysis of all-RAS. AB - INTRODUCTION: We investigated the impact of mutations in KRAS exons 3-4 and NRAS exons 2-3 in addition to KRAS exon 2, so-called all-RAS mutations, in patients with colorectal liver metastasis (CLM) undergoing hepatic resection. METHODS: We analyzed 421 samples from CLM patients for their all-RAS mutation status to compare the overall survival rate (OS), recurrence-free survival rate (RFS), and the pattern of recurrence between the patients with and without RAS mutations. RESULTS: RAS mutations were detected in 191 (43.8%). Thirty-two rare mutations (12.2%) were detected in 262 patients with KRAS exon 2 wild-type. After excluding 79 patients who received anti-EGFR antibody therapy, 168 were classified as all RAS wild-type, and 174 as RAS mutant-type. A multivariate analysis of factors associated with OS and RFS identified the RAS status as an independent factor (OS; hazard ratio [HR] = 1.672, P = 0.0031, RFS; HR = 1.703, P = 0.0024). Recurrence with lung metastasis was observed significantly more frequent in patients with RAS mutations than in patients with RAS wild-type (P = 0.0005). CONCLUSIONS: Approximately half of CLM patients may have a RAS mutation. CLM patients with RAS mutations had a significantly worse survival rate in comparison to patients with RAS wild-type, regardless of the administration of anti-EGFR antibody therapy. PMID- 29194648 TI - High-performance serial block-face SEM of nonconductive biological samples enabled by focal gas injection-based charge compensation. AB - A longstanding limitation of imaging with serial block-face scanning electron microscopy is specimen surface charging. This charging is largely due to the difficulties in making biological specimens and the resins in which they are embedded sufficiently conductive. Local accumulation of charge on the specimen surface can result in poor image quality and distortions. Even minor charging can lead to misalignments between sequential images of the block-face due to image jitter. Typically, variable-pressure SEM is used to reduce specimen charging, but this results in a significant reduction to spatial resolution, signal-to-noise ratio and overall image quality. Here we show the development and application of a simple system that effectively mitigates specimen charging by using focal gas injection of nitrogen over the sample block-face during imaging. A standard gas injection valve is paired with a precisely positioned but retractable application nozzle, which is mechanically coupled to the reciprocating action of the serial block-face ultramicrotome. This system enables the application of nitrogen gas precisely over the block-face during imaging while allowing the specimen chamber to be maintained under high vacuum to maximise achievable SEM image resolution. The action of the ultramicrotome drives the nozzle retraction, automatically moving it away from the specimen area during the cutting cycle of the knife. The device described was added to a Gatan 3View system with minimal modifications, allowing high-resolution block-face imaging of even the most charge prone of epoxy-embedded biological samples. PMID- 29194650 TI - Evolution on the bright side of life: microorganisms and the evolution of mutualism. AB - Mutualistic interactions, where two interacting species have a net beneficial effect on each other's fitness, play a crucial role in the survival and evolution of many species. Despite substantial empirical and theoretical work in past decades, the impact of these interactions on natural selection is not fully understood. In addition, mutualisms between microorganisms have been largely ignored, even though they are ecologically important and can be used as tools to bridge the gap between theory and empirical work. Here, I describe two problems with our current understanding of natural selection in mutualism and highlight the properties of microbial mutualisms that could help solve them. One problem is that bias and methodological problems have limited our understanding of the variety of mechanisms by which species may adapt to mutualism. Another problem is that it is rare for experiments testing coevolution in mutualism to address whether each species has adapted to evolutionary changes in its partner. These problems can be addressed with genome resequencing and time-shift experiments, techniques that are easier to perform in microorganisms. In addition, microbial mutualisms may inspire novel insights and hypotheses about natural selection in mutualism. PMID- 29194649 TI - Localization of the glucosinolate biosynthetic enzymes reveals distinct spatial patterns for the biosynthesis of indole and aliphatic glucosinolates. AB - Glucosinolates constitute the primary defense metabolites in Arabidopsis thaliana (Arabidopsis). Indole and aliphatic glucosinolates, biosynthesized from tryptophan and methionine, respectively, are known to serve distinct biological functions. Although all genes in the biosynthetic pathways are identified, and it is known where glucosinolates are stored, it has remained elusive where glucosinolates are produced at the cellular and tissue level. To understand how the spatial organization of the different glucosinolate biosynthetic pathways contributes to their distinct biological functions, we investigated the localization of enzymes of the pathways under constitutive conditions and, for indole glucosinolates, also under induced conditions, by analyzing the spatial distribution of several fluorophore-tagged enzymes at the whole plant and the cellular level. We show that key steps in the biosynthesis of the different types of glucosinolates are localized in distinct cells in separate as well as overlapping vascular tissues. The presence of glucosinolate biosynthetic enzymes in parenchyma cells of the vasculature may assign new defense-related functions to these cell types. The knowledge gained in this study is an important prerequisite for understanding the orchestration of chemical defenses from site of synthesis to site of storage and potential (re)mobilization upon attack. PMID- 29194651 TI - Antenatal anemia increases the risk of receiving postpartum red blood cell transfusions although the overall risk of transfusion is low. AB - BACKGROUND: The objective was to determine if antenatal anemia is associated with postpartum red blood cell (RBC) transfusion. STUDY DESIGN AND METHODS: Women who gave birth at a regional, tertiary care maternity hospital between December 1, 2015, and September 31, 2016, with a documented antenatal hemoglobin (Hb) concentration were included. Women were grouped into those who were either anemic (Hb < 11.0 g/dL) or nonanemic. The change in Hb concentration and RBC transfusion rates were compared between the anemic and nonanemic women, as well as by the mode of delivery (vaginal vs. Cesarean). To estimate the volume of blood loss in a normal delivery, the mean postpartum Hb concentration decrease for the not transfused women was calculated by subtracting the nadir postpartum Hb concentration from the antenatal Hb concentration and averaging these concentrations according to delivery route. RESULTS: Of 8039 cases analyzed, 1562 (19%) had antenatal anemia and 6477 (81%) were nonanemic. Of the anemic women, 57 (3.6%) received an RBC transfusion compared to 49 (0.76%) of the nonanemic women (p = 0.0001; odds ratio, 4.97; 95% confidence interval, 3.38-7.31). Antenatal anemia was significantly associated with receiving an RBC transfusion regardless of mode of delivery for those who delivered vaginally (p = 0.0001) or by Cesarean (p = 0.0001) compared to those who were nonanemic. The mean postpartum Hb concentration decrease was 1.12 +/- 1.12 g/dL for vaginal deliveries and 1.34 +/- 0.21 g/dL for Cesarean deliveries in the not transfused women (p = 0.0001). CONCLUSION: Although the overall rate of transfusion was low, antenatal anemia was significantly associated with receiving a postpartum RBC transfusion. PMID- 29194652 TI - Outcomes of red blood cell transfusions prescribed in organ donors by the Digital Intern, an electronic decision support algorithm. AB - BACKGROUND: The Digital Intern (DI) is an electronic decision support tool for the management of organ donors. One algorithm determines the dose, in units of red blood cells to be transfused, based on hematocrit (Hct) thresholds and targets. The effectiveness of the transfusion dose calculated by the DI in terms of achieving the selected Hct target and the duration of the targeted dose is not known. STUDY DESIGN AND METHODS: This was a retrospective study to describe the outcomes of transfusions prescribed by the DI. Pre- and posttransfusion Hct levels were compared to define response and all posttransfusion Hct values were plotted to evaluate the duration of the prescribed dose. RESULTS: A total of 120 organ donors were studied and 22 donors had 28 transfusions (six were transfused twice). The transfused donors were a mix of trauma and medical admissions and brain death and cardiac death donors. The transfusion target of 24% Hct was attained in 96% of transfusions. The mean number of units transfused was 1.4 and the mean time from transfusion to procurement was 19.8 hours. There was a decline in Hct over time after transfusion in all but one case with a mean decline of 1.9% Hct over 13 hours. Six donors were transfused twice, likely due to a longer donor time period (41.7 hr vs. 27 hr). CONCLUSIONS: The DI provided transfusion dosing that achieved the desired threshold in the majority of organ donors transfused. Ongoing work focuses on application of this technology to transfusions in general patient populations. PMID- 29194653 TI - Electrophysiological markers predicting impeding AV-block during ablation of atrioventricular nodal reentry tachycardia. AB - BACKGROUND: Radiofrequency (RF) ablation of the slow pathway (SP) in atrioventricular nodal reentry tachycardia (AVNRT) is occasionally complicated with atrioventricular block (AVB) often predicted by junctional beats (JB) with loss of ventriculo-atrial (VA) conduction. METHODS: We analyzed retrospectively 153 patients undergoing ablation of SP for typical AVNRT. Patients were divided into two age groups: 127 <= 70 years and 26 > 70 years. We analyzed the interval between the atrial electrogram in the His-bundle position and the distal ablation catheter [A(H)-A(RFd)] and between the distal ablation catheter and the proximal coronary sinus catheter [A(RFd)-A(CS)] before RF applications with and without JB. We evaluated if these intervals can be used as predictors of JB incidence and also of JB with loss of VA conduction. We also assessed if age influences the risk of loss of VA conduction. RESULTS: The A(H)-A(RFd) and A(RFd)-A(CS) intervals were significantly shorter in RF applications causing JB than those without JB (33 +/- 11 ms vs 39 +/- 9 ms, P < 0.001, 14 +/- 9 ms vs 20 +/- 7 ms, P < 0.001, respectively). The A(H)-A(RFd) and A(RFd)-A(CS) intervals were also significantly shorter in RFs causing JB with VA block than those with VA conduction (29 +/- 11 ms vs 35 +/- 11 ms, P < 0.001, 8 +/- 8 ms vs 17 +/- 8 ms, P < 0.001, respectively). Patients > 70 years had shorter intervals (36 +/- 11 ms vs 29 +/- 8 ms, P = 0.012, 17 +/- 8 ms vs 13 +/- 7 ms, P = 0.027, respectively), while VA block was more common in this age group. CONCLUSIONS: The A(H)-A(RFd) and A(RFd)-A(CS) intervals can be used as markers for predicting JB occurrence as well as impending AVB. JB with loss of VA conduction occur more often in older patients possibly due to a higher position of SP. PMID- 29194654 TI - Safety and efficacy analysis of one-stop intervention for treating nonvalvular atrial fibrillation. AB - BACKGROUND: Nonvalvular atrial fibrillation (AF) is a common arrhythmia. The treatment strategy for AF mainly includes controlling symptoms and decreasing the rate of complications. Our study aimed to evaluate the safety and efficacy of combination treatment of catheter ablation and left atrial appendage (LAA) closure (one-stop intervention) in patients with nonvalvular AF. METHODS AND RESULTS: Thirty-four patients with symptomatic AF (mean CHA2 DS2 -VASc score 4.1 +/- 1.3, mean HAS-BLED score 3.8 +/- 1.2) were included. Patients first received radiofrequency-based left atrial ablation, and then the Watchman device (Boston Scientific, Natick, MA, USA) or AMPLATZER Cardiac Plug (ACP) (St. Jude Medical, Inc., St. Paul, MN, USA) was implanted for LAA closure. Follow-up was performed at 45 days and 3 months after LAA closure to assess for recurrence of AF and prevent stroke. Radiofrequency ablation and LAA closure were successful in 100% of patients without evidence of residual flow at the final transesophageal echocardiography evaluation. A Watchman device was implanted in 29 (85.3%) patients, and an ACP was implanted in five (14.7%) patients. No device-related thrombus formation or embolization was identified at the 45-day or 3-month follow up. Serious complications, including death, transient ischemic attack, ischemic or hemorrhagic stroke, or major bleeding, were also not identified during the follow-ups. CONCLUSION: For symptomatic patients with nonvalvular AF and a high risk of stroke, the one-stop intervention is feasible, safe, and efficacious. PMID- 29194655 TI - A classic textbook flutter. PMID- 29194656 TI - Head motion correction based on filtered backprojection for x-ray CT imaging. AB - PURPOSE: For head x-ray CT imaging, the head needs to remain motionless during the scan. In clinical practice, however, head motion is sometimes unavoidable depending on the patient. The motion can occur abruptly during the scan and can be unpredictable. It thereby causes motion artifacts such as tissue blurring or doubled edges around the skull area. To mitigate this problem, we propose a 3D head motion estimation (ME) and compensation algorithm based on filtered backprojection. METHODS: If a patient moves his or her head during the scan, a motion-corrupted sinogram is obtained. Modeling the head motion as a 3D rigid transformation, we develop a motion-compensated (MC) reconstruction algorithm based on the FDK algorithm. To determine the head motion of a rigid transformation, we propose two optimization-based ME schemes depending on the degree of head motion, both of which are performed by updating motion parameters and the corresponding MC reconstructed image alternatively until the proposed cost function is minimized for the MC reconstructed image. In particular, to improve the robustness in the case of large motion, we propose attaching a fiducial marker to the head so that more reliable motion parameters can be initialized by determining the marker position, before the optimization. To evaluate the proposed algorithm, a numerical phantom with realistic, continuous, and smoothly varying motion, and a moving physical phantom are used with a gantry rotation time of 1 s. RESULTS: In the simulation using a numerical phantom and in the experiment using a physical phantom, the proposed algorithm provides well restored 3D motion-compensated images in both cases of small and large motion. In particular, in the case of large motion of the physical phantom, using a fiducial marker, we obtain remarkable improvement of image quality in cerebral arteries and a lesion as well as the skull. Quantitative evaluations using the image sharpness and root-mean-square error also show noticeable improvement of image quality in both simulations and experiments. CONCLUSIONS: We propose a framework for head motion correction in an axial CT scan, which consists of motion estimation and compensation steps. Two image-based ME algorithms for rigid motion tracking are developed according to the degree of head motion. The estimated motion information is then used for MC image reconstruction. Both motion estimation and compensation algorithms are based on computationally efficient filtered backprojection. Excellent performance of the proposed framework is illustrated by means of simulations using a numerical phantom and experiments using a physical phantom. PMID- 29194657 TI - A proposal to create an extension to the European baseline series. AB - BACKGROUND: The current European baseline series consists of 30 allergens, and was last updated in 2015. OBJECTIVES: To use data from the European Surveillance System on Contact Allergies (ESSCA) to propose an extension to the European baseline series in response to changes in environmental exposures. METHODS: Data from departmental and national extensions to the baseline series, together with some temporary additions from departments contributing to the ESSCA, were collated during 2013-2014. RESULTS: In total, 31689 patients were patch tested in 46 European departments. Many departments and national groups already consider the current European baseline series to be a suboptimal screen, and use their own extensions to it. The haptens tested are heterogeneous, although there are some consistent themes. Potential haptens to include in an extension to the European baseline series comprise sodium metabisulfite, formaldehyde-releasing preservatives, additional markers of fragrance allergy, propolis, Compositae mix, and 2-hydroxyethyl methacrylate. CONCLUSION: In combination with other published work from the ESSCA, changes to the current European baseline series are proposed for discussion. As well as addition of the allergens listed above, it is suggested that primin and clioquinol should be deleted from the series, owing to reduced environmental exposure. PMID- 29194658 TI - Mycorrhizal tomato plants fine tunes the growth-defence balance upon N depleted root environments. AB - In low nutritive environments, the uptake of N by arbuscular mycorrhizal (AM) fungi may confer competitive advantages for the host. The present study aims to understand how mycorrhizal tomato plants perceive and then prepare for an N depletion in the root environment. Plants colonized by Rhizophagus irregularis displayed improved responses to a lack of N than nonmycorrhizal (NM) plants. These responses were accomplished by a complex metabolic and transcriptional rearrangement that mostly affected the gibberellic acid and jasmonic acid pathways involving DELLA and JAZ1 genes, which were responsive to changes in the C/N imbalance of the plant. N starved mycorrhizal plants showed lower C/N equilibrium in the shoots than starved NM plants and concomitantly a downregulation of the JAZ1 repressor and the increased expression of the DELLA gene, which translated into a more active oxylipin pathway in mycorrhizal plants. In addition, the results support a priorization in AM plants of stress responses over growth. Therefore, these plants were better prepared for an expected stress. Furthermore, most metabolites that were severely reduced in NM plants following the N depletion remained unaltered in starved AM plants compared with those normally fertilized, suggesting that the symbiosis buffered the stress, improving plant development in a stressed environment. PMID- 29194659 TI - A stress-associated protein, AtSAP13, from Arabidopsis thaliana provides tolerance to multiple abiotic stresses. AB - Members of Stress-Associated Protein (SAP) family in plants have been shown to impart tolerance to multiple abiotic stresses, however, their mode of action in providing tolerance to multiple abiotic stresses is largely unknown. There are 14 SAP genes in Arabidopsis thaliana containing A20, AN1, and Cys2-His2 zinc finger domains. AtSAP13, a member of the SAP family, carries two AN1 zinc finger domains and an additional Cys2-His2 domain. AtSAP13 transcripts showed upregulation in response to Cd, ABA, and salt stresses. AtSAP13 overexpression lines showed strong tolerance to toxic metals (AsIII, Cd, and Zn), drought, and salt stress. Further, transgenic lines accumulated significantly higher amounts of Zn, but less As and Cd accumulation in shoots and roots. AtSAP13 promoter-GUS fusion studies showed GUS expression predominantly in the vascular tissue, hydathodes, and the apical meristem and region of root maturation and elongation as well as the root hairs. At the subcellular level, the AtSAP13-eGFP fusion protein was found to localize in both nucleus and cytoplasm. Through yeast one-hybrid assay, we identified several AP2/EREBP family transcription factors that interacted with the AtSAP13 promoter. AtSAP13 and its homologues will be highly useful for developing climate resilient crops. PMID- 29194661 TI - Solar UV-B radiation and ethylene play a key role in modulating effective defenses against Anticarsia gemmatalis larvae in field-grown soybean. AB - Solar UV-B radiation has been reported to enhance plant defenses against herbivore insects in many species. However, the mechanism and traits involved in the UV-B mediated increment of plant resistance are unknown in crops species, such as soybean. Here, we studied defense-related responses in undamaged and Anticarsia gemmatalis larvae-damaged leaves of two soybean cultivars grown under attenuated or full solar UV-B radiation. We determined changes in jasmonates, ethylene (ET), salicylic acid, trypsin protease inhibitor activity, flavonoids, and mRNA expression of genes related with defenses. ET emission induced by Anticarsia gemmatalis damage was synergistically increased in plants grown under solar UV-B radiation and was positively correlated with malonyl genistin concentration, trypsin proteinase inhibitor activity and expression of IFS2, and the pathogenesis protein PR2, while was negatively correlated with leaf consumption. The precursor of ET, aminocyclopropane-carboxylic acid, applied exogenously to soybean was sufficient to strongly induce leaf isoflavonoids. Our results showed that in field-grown soybean isoflavonoids were regulated by both herbivory and solar UV-B inducible ET, whereas flavonols were regulated by solar UV-B radiation only and not by herbivory or ET. Our study suggests that, although ET can modulate UV-B-mediated priming of inducible plant defenses, some plant defenses, such as isoflavonoids, are regulated by ET alone. PMID- 29194662 TI - Quantitative Predictive Models for the Degree of Disability After Acute Ischemic Stroke. AB - Although stroke is a leading cause of disability, the quantitative relationship between baseline clinical and imaging characteristics and long-term disability outcomes has rarely been studied. Prospectively collected clinical data from 405 patients with acute ischemic stroke including brain magnetic resonance images (MRIs) and disability outcomes assessed using the modified Rankin Scale (mRS) 3 month after the onset of disease were analyzed using a proportional odds cumulative logit model implemented in NONMEM. The relationship between the difference in lesion volume (DLV) - lesion volume measured by brain MRI 5 days later - lesion volume at the onset of the disease, and the mRS measured at 3 months (mRS3) was modeled first, and the potential covariates were tested. The Emax model best described the relationship between DLV and the logit probability of each mRS3. DLV, baseline stroke severity, age, and diabetes mellitus were identified as significant predictors of the probabilities of mRS3. The quantitative model constructed in the current analysis will enable us to predict the long-term disabilities of the patients with acute ischemic stroke using the patient-specific MRI and other clinical information, which will be useful for individualizing therapies and for making the clinical development of a novel drug more efficient. PMID- 29194660 TI - Dietary exposure assessment of cyadox based on tissue depletion of cyadox and its major metabolites in pigs, chickens, and carp. AB - The tissue kinetics of cyadox, an antibacterial agent used in food animals, and its major metabolites in pigs, chickens, and carp were investigated followed by a complete dietary exposure assessment to evaluate the food safety of cyadox. Cyadox and its major metabolites, bisdeoxycyadox (Cy1), 4-desoxycyadox (Cy2), N (quinoxaline-2-methyl)-cyanide acetyl hydrazine (Cy4), quinoxaline-2-carboxylic acid (Cy6), and 2-hydromethyl-3-hydroxy-quinoxaline (Cy12), were simultaneously quantitated with a high-performance liquid chromatography-ultraviolet (HPLC-UV) method. Pigs, chickens, and carp were fed with 150 mg/kg cyadox in feed for consecutive 60, 40, and 30 days, respectively. The residue amount of cyadox and its major metabolites in liver, kidney, muscle, and fat (skin) tissues was determined. Cy2 was below the limit of quantitation even at the withdrawal time of 6 hr, cyadox, Cy4, Cy6, and Cy12 could be detected at 6-24 hr with low level less than 50 MUg/kg. By contrast, Cy1 persisted for 3 days in the kidney of pigs and chickens, and in the liver of carp. Based on these residue depletion data and previous toxicology results, the global estimated chronic dietary exposure assessment of cyadox for general population was conducted, indicating a zero withdrawal time (WDT) may be appropriate for cyadox in food animals when used in feed for prolonged administration. These results provide analytical techniques and safety standards suitable for residue monitoring of cyadox in food animals. PMID- 29194663 TI - Nanoemulsion from essential oil of Pterodon emarginatus (Fabaceae) shows in vitro efficacy against monogeneans of Colossoma macropomum (Pisces: Serrasalmidae). AB - Outbreaks of diseases pose a major threat to sustainable aquaculture development worldwide. Application of herbal products to combat parasitic diseases provides an alternative approach for sustainable aquaculture. This study investigated the in vitro antiparasitic effects of an oil-in-water nanoemulsion prepared using the essential oil from Pterodon emarginatus, against monogeneans infesting Colossoma macropomum. Gill arches from C. macropomum (47.6 +/- 14.5 g and 13.5 +/- 1.4 cm) that were naturally parasitized by Anacanthorus spathulatus, Notozothecium janauachensis and Mymarothecium boegeri were immersed in different dispersions of the P. emarginatus nanoemulsions (0, 50, 100, 200, 400 and 600 mg/L). The major compounds presented in the essential oil of P. emarginatus were beta-elemene, beta-caryophyllene and alpha-humulene. Characterization of these nanoemulsions showed that they have a small mean droplet size and low polydispersity index, which is concordant with stable systems. In this in vitro trial, the P. emarginatus nanoemulsion concentrations of 100, 200, 400 and 600 mg/L presented 100% helminthic efficacy against monogeneans of the gills of C. macropomum. The highest two concentrations used (400 and 600 mg/L) were seen to immobilize the parasites after only 15 min. Therefore, it would be worthwhile testing these concentrations in therapeutic baths against monogeneans of C. macropomum. PMID- 29194664 TI - The plant hormone salicylic acid interacts with the mechanism of anti-herbivory conferred by fungal endophytes in grasses. AB - The plant hormone salicylic acid (SA) is recognized as an effective defence against biotrophic pathogens, but its role as regulator of beneficial plant symbionts has received little attention. We studied the relationship between the SA hormone and leaf fungal endophytes on herbivore defences in symbiotic grasses. We hypothesize that the SA exposure suppresses the endophyte reducing the fungal produced alkaloids. Because of the role that alkaloids play in anti-herbivore defences, any reduction in their production should make host plants more susceptible to herbivores. Lolium multiflorum plants symbiotic and nonsymbiotic with the endophyte Epichloe occultans were exposed to SA followed by a challenge with the aphid Rhopalosiphum padi. We measured the level of plant resistance to aphids, and the defences conferred by endophytes and host plants. Symbiotic plants had lower concentrations of SA than did the nonsymbiotic counterparts. Consistent with our prediction, the hormonal treatment reduced the concentration of loline alkaloids (i.e., N-formyllolines and N-acetylnorlolines) and consequently decreased the endophyte-conferred resistance against aphids. Our study highlights the importance of the interaction between the plant immune system and endophytes for the stability of the defensive mutualism. Our results indicate that the SA plays a critical role in regulating the endophyte-conferred resistance against herbivores. PMID- 29194665 TI - Efficacy and safety of a new human fibrinogen concentrate in patients with congenital fibrinogen deficiency: an interim analysis of a Phase III trial. AB - BACKGROUND: Fibrinogen concentrate is the preferred choice for fibrinogen replacement in congenital fibrinogen deficiency. This study investigated hemostatic efficacy of a new plasma-derived, double virus-inactivated (using two dedicated virus inactivation/elimination steps) human fibrinogen concentrate for on-demand treatment of bleeding episodes (BEs) and surgical prophylaxis. STUDY DESIGN AND METHODS: In this planned interim analysis of a prospective, multinational Phase III study (NCT02267226), 13 patients with afibrinogenemia (>=12 years) received fibrinogen concentrate (FIBRYGA, Octapharma AG). Hemostatic efficacy was assessed by investigators and an independent data monitoring and endpoint adjudication committee (IDMEAC) using objective four-point criteria and by thromboelastometry maximum clot firmness (MCF). RESULTS: Fibrinogen concentrate was used on-demand to treat 23 BEs in 11 patients, with 21 (91.3%) requiring a single infusion only. Treatment success was 95.7% (90% confidence interval [CI], 0.81-1.00; assessment missing for one BE) by investigators and 100% (90% CI, 0.88-1.00) by IDMEAC. Mean MCF increased significantly from 0.0 to 6.5 mm (95% CI, 5.65-7.40; p < 0.0001) at 1 hour postinfusion of a median (range) dose of 58.8 (33.9-101.7) mg/kg per BE. Four patients received fibrinogen concentrate as surgical prophylaxis, with intraoperative and postoperative treatment success rated 100% (90% CI, 0.50-1.00) by investigators and IDMEAC (median [range] dose per surgery 93.5 [34.1-225.4] mg/kg). No additional hemostatic interventions were required. No deaths, thromboses, or seroconversions were reported. CONCLUSION: These data showed that the new fibrinogen concentrate was efficacious for on-demand treatment of acute bleeding and surgical prophylaxis in congenital afibrinogenemia patients. PMID- 29194666 TI - Feasibility of Implementation of a Parenting Intervention with Karen Refugees Resettled from Burma. AB - Parents and children exposed to war and relocation have high rates of negative relational and mental health outcomes. This study tested the feasibility of implementing an adapted evidence-based parenting intervention for contexts of trauma and relocation stress. Eleven Karen refugee caregivers from Burma participated in the intervention. Participants and a focal child completed ethnographic interviews as well as structured assessments at baseline and follow up. Caregivers reported changes in their teaching, directions, emotional regulation, discipline, and child compliance. Children reported changes in these areas and in positive parent involvement. Caregivers reported higher mental health distress immediately after the intervention, potentially due to increased awareness. Researchers made personalized referrals for counseling services as needed. Children reported a decrease in mental health symptoms. PMID- 29194667 TI - Evaluation of the impact of banking umbilical cord blood units with high cell dose for ethnically diverse patients. AB - BACKGROUND: Umbilical cord blood units provide an important stem cell source for transplantation, particularly for patients of ethnic diversity who may not have suitably matched available, adult-unrelated donors. However, with the cost of cord blood unit acquisition from public banks significantly higher than that for adult-unrelated donors, attention is focused on decreasing cost yet still providing cord blood units to patients in need. Historical practices of banking units with low total nucleated cell counts, including units with approximately 90 * 107 total nucleated cells, indicates that most banked cord blood units have much lower total nucleated cell counts than are required for transplant. STUDY DESIGN AND METHODS: The objective of this study was to determine the impact on the ability to identify suitable cord blood units for transplantation if the minimum total nucleated cell count for banking were increased from 90 * 107 to 124 or 149 * 107 . We analyzed ethnically diverse patients (median age, 3 years) who underwent transplantation of a single cord blood unit in 2005 to 2016. A cord blood unit search was evaluated to identify units with equal or greater human leukocyte antigen matching and a greater total nucleated cell count than that of the transplanted cord blood unit (the replacement cord blood unit). RESULTS: If the minimum total nucleated cell count for banking increased to 124 or 149 * 107 , then from 75 to 80% of patients would still have at least 1 replacement cord blood unit in the current (2016) cord blood unit inventory. The best replacement cord blood units were often found among cords with the same ethnic background as the patient. CONCLUSION: The current data suggest that, if the minimum total nucleated cell count were increased for banking, then it would likely lead to an inventory of more desirable cord blood units while having minimal impact on the identification of suitable cord blood units for transplantation. PMID- 29194668 TI - Is an endoscopic examination associated with transfusion-transmissible infections? A systematic review and meta-analysis. AB - BACKGROUND: The purpose of a donor medical questionnaire is to identify the blood donor's history relative to the current known blood-safety risks. A temporary deferral from blood donation after an endoscopic examination is enforced because of the reusable nature of the endoscope and close contact with the inner body. The objective of this systematic review was to find the best available evidence on the association between an endoscopic examination and the risk of transfusion transmissible infections. METHODS: Studies from five databases investigating the link between an endoscopic examination and transfusion-transmissible infections (hepatitis B virus, hepatitis C virus, human immunodeficiency virus infection, Treponema pallidum) were retained and assessed independently by two reviewers. The association between endoscopy and transfusion-transmissible infections was identified by conducting meta-analyses and calculating pooled effect measures (odds ratios and 95% confidence intervals). The Grading of Recommendations, Assessment, Development, and Evaluation methodology was used to assess the quality of evidence. RESULTS: We identified 7571 references and finally included 29 observational studies. A significant association between an endoscopic examination and hepatitis B virus infection (pooled odds ratio [OR], 2.21; 95% confidence interval [CI], 1.26-3.86; p = 0.005) or hepatitis C virus infection (pooled OR 1.76, 95% CI, 1.45-2.14; p < 0.00001) was found. The level of evidence was considered as "very low" due to the type of study design (i.e., observational) and indirect study populations (i.e., no blood donor populations). CONCLUSION: An endoscopic examination is associated with an increased hepatitis B virus or hepatitis C virus infection risk. Further high-quality trials are required to formulate stronger evidence-based recommendations on endoscopic examination as a blood donor deferral criterion. PMID- 29194669 TI - Red blood cell transfusion in adult palliative care: a systematic review. AB - BACKGROUND: The risks and benefits of red blood cell (RBC) transfusion in palliative care patients remain poorly understood. We reviewed the literature to summarize available information on RBC transfusion in this population. STUDY DESIGN AND METHODS: We searched electronic databases (MEDLINE, Embase, PsycINFO, CINAHL) from inception through September 2016 to identify studies reporting data on palliative patients receiving RBC transfusion. Original studies that assessed RBC transfusion as an intervention and reported at least one clinical outcome were included. Study characteristics, results on transfusion-related outcomes, and authors' conclusions on the value of transfusion in palliative patients were abstracted and reported. RESULTS: We identified 1839 studies, of which 137 were selected for data extraction and 13 were included (11 case series, one prospective cohort, and one retrospective cohort). Nine studies addressed symptom relief following transfusion using subjective symptom scales, of which eight (89%) indicated some degree of short-term benefit and one study (11%) showed no benefit. Posttransfusion survival was reported in four studies-one demonstrated prolonged survival in patients receiving RBC transfusion; three had no comparison group. Other outcomes reported included hemoglobin values posttransfusion in four studies and adverse events following transfusion in three studies. CONCLUSIONS: In palliative care, RBC transfusion may provide symptom relief and improve subjective well-being, though the duration and magnitude of this effect, and transfusion-associated risks specific to this population remain unclear. Currently, no high quality evidence exists to support or guide the use of RBC transfusion in this population. Moreover, the clinical heterogeneity within the palliative population limits the interpretation of most studies. PMID- 29194670 TI - Endoscopic and surgical removal of oesophageal and gastric fishhook foreign bodies in 33 animals. AB - OBJECTIVES: To describe the location, retrieval, frequency of surgery and complications associated with fishhook foreign bodies. MATERIALS AND METHODS: Retrospective evaluation of the medical records of cats and dogs admitted between 2010 and 2016 after fishhook ingestion. RESULTS: A total of 33 cases (2 cats and 31 dogs) were included. The most common locations were the proximal oesophagus [12/33 (36%)] and stomach [11/33 (33%)]. Endoscopic retrieval was successful in 27 of 33 cases (82%); oesophageal perforation was the only recorded complication, occurring in six of 33 (18%) cases. Surgery was performed in six cases (18%), and no early complications were recorded. The survival rate was 100%. CLINICAL SIGNIFICANCE: The endoscopic removal of ingested fishhooks is highly successful. In the present study, survival to discharge was 100%, even in cases of oesophageal perforation or in cases requiring surgery.

PMID- 29194672 TI - Letter response: Reporting of mitotic rate in cutaneous melanoma. PMID- 29194673 TI - Transected thin melanoma: Implications for sentinel lymph node staging. AB - BACKGROUND AND OBJECTIVES: Indications for sentinel lymph node (SLN) biopsy in patients with thin melanoma (<=1 mm thick) are controversial. We asked whether deep margin (DM) positivity at initial biopsy of thin melanoma is associated with SLN positivity. METHODS: Cases were identified using prospectively maintained databases at two melanoma centers. Patients who had undergone SLN biopsy for melanoma <=1 mm were included. DM status was assessed for association with SLN metastasis in univariate and multivariate analyses. RESULTS: 1413 cases were identified, but only 1129 with known DM status were included. 39% of patients had a positive DM on original biopsy. DM-positive and DM-negative patients did not differ significantly in primary thickness, ulceration, or mitotic activity. DM positive and DM-negative patients had similar incidence of SLN metastasis (5.7% vs 3.5%; P = 0.07). Positive DM was not associated with SLN metastasis on univariate analysis (OR 1.69, 95% CI: 0.95-3.00, P = 0.07) or on multivariate analysis adjusted for Breslow depth, Clark level, mitotic rate, and ulceration (OR = 1.59, 95% CI: 0.89-2.85; P = 0.12). CONCLUSIONS: For patients with thin melanoma, a positive DM on initial biopsy is not associated with risk of SLN metastasis, so DM positivity should not be considered an indication for SLN staging in an otherwise low-risk patient. PMID- 29194674 TI - A whole genome sequence association study for puberty in a large Duroc * Erhualian F2 population. AB - A large proportion of gilts and sows are culled from reproduction populations because of anestrus and pubertal reproductive failure. Selecting early onset of puberty gilts has a favorable effect on sows' reproductivity. However, age at puberty is hard to be routinely measured in commercial herds. With molecular genetic predictors, identifying individuals that have a propensity for early onset of puberty can be simplified. We previously performed genome scanning and a genome-wide association study for puberty in an F2 resource population using 183 microsatellites and 62 125 SNPs respectively. The detection power and resolution of identified quantitative trait loci were very low. Herein, we re-sequenced 19 founders of the F2 resource population in high coverage, and whole genome sequences of F2 individuals were imputed to perform an association study for reproductive traits. A total of 2339 SNPs associated with pubertal reproductive failure were identified in the region of 30.94-40.74 Mb on SSC7, with the top one, positioned at 33.36 Mb, explaining 16% of the phenotypic variances. We improved the magnitude of the P-value by 10E+5 to 10E+7 using the whole genome sequence rather than using low/middle density markers as in previous studies, and we narrowed down the QTL confidence interval to 5.25 Mb. Combining the annotation of gene function, RAB23 and BAK1 were perceived as the most compelling candidate genes. The identified loci may be useful in culling sows failing to show estrus by marker-assisted selection to increase reproductive efficiency of swine herds. PMID- 29194675 TI - Peacekeepers are cross-dressed in the liver land. PMID- 29194676 TI - Extremely high-frequency electromagnetic radiation enhances neutrophil response to particulate agonists. AB - The growing use of extremely high-frequency electromagnetic radiation (EHF EMR) in information and communication technology and in biomedical applications has raised concerns regarding the potential biological impact of millimeter waves (MMWs). Here, we elucidated the effects of MMW radiation on neutrophil activation induced by opsonized zymosan or E. coli in whole blood ex vivo. After agonist addition to blood, two samples were prepared. A control sample was incubated at ambient conditions without any treatment, and a test sample was exposed to EHF EMR (32.9-39.6 GHz, 100 W/m2 ). We used methods that allowed us to assess the functional status of neutrophils immediately after exposure: oxidant production levels were measured by luminol-dependent chemiluminescence, and morphofunctional changes to neutrophils were observed in blood smears. Results revealed that the response of neutrophils to both agonists was intensified if blood was exposed to MMW radiation for 15 min. Neutrophils were intact in both the control and irradiated samples if no agonist was added to blood before incubation. Similarly, exposing suspensions of isolated neutrophils in plasma to MMW radiation enhanced cell response to both zymosan and E. coli. Heating blood samples was shown to be the primary mechanism underlying enhanced EHF EMR-induced oxidant production by neutrophils in response to particulate agonists.

AB - A systematic review of the literature was performed on the association of chronic inflammatory demyelinating polyneuropathy (CIDP) with malignancy. Hematological disorders are the most common association, particulalry non-Hodgkin lymphoma. CIDP frequently precedes the malignancy diagnosis, and there is a favorable CIDP response to treatment more than 70% of the time. Melanoma is the second most common association and may be accompanied by antiganglioside antibodies; CIDP shows a good response to immunotherapy. Other cancers are rare, with variable timings and presentations but good responses to immunomodulation and/or cancer therapy. Unusual neurological features such as ataxia, distal/upper limb predominance, or cranial/respiratory/autonomic involvement may suggest associated malignancy as may abdominal pain, diarrhea/constipation, poor appetite/weight loss, dermatological lesions, and lymphadenopathy. In the appropriate clinical and electrophysiological setting, CIDP associated with cancer should be considered. Immunomodulatory therapy, cancer treatment alone, or a combination may be effective.

AB - : In patients with acute liver failure (ALF), elevated prothrombin time and thrombocytopenia can fuel a perception of a bleeding tendency. However, the incidence, site, risk factors, and clinical significance of bleeding complications have not been quantified in a large cohort of patients with ALF. We studied 1,770 adult patients enrolled in the ALF Study Group Registry between 1998 and 2016. Bleeding complications and blood component transfusions were collected for 7 days after admission. The relationship of bleeding complications to 21-day mortality was assessed. Despite a median international normalized ratio of 2.7 and platelet count of 96 * 109 /L on admission, bleeding complications were observed in only 187 patients (11%), including 173 spontaneous and 22 postprocedural bleeding episodes. Eighty-four percent of spontaneous bleeding episodes were from an upper gastrointestinal source and rarely resulted in red blood cell transfusion. Twenty patients experienced an intracranial bleed; half of these occurred spontaneously and half after intracranial pressure monitor placement, and this was the proximate cause of death in 20% and 50%, respectively. Bleeders and patients who received red blood cell transfusions were more acutely ill from extrahepatic organ system failure but not from hepatocellular failure. Consistent with this observation, bleeding complications were associated with lower platelet counts but not higher international normalized ratio. Transfusion of any blood component was associated with nearly 2 fold increased death or need for liver transplantation at day 21, but bleeding complications were the proximate cause of death in only 5% of cases. CONCLUSIONS: Despite a perceived bleeding diathesis, clinically significant bleeding is uncommon in patients with ALF; bleeding complications in patients with ALF are markers of severe systemic inflammation rather than of coagulopathy and so portend a poor prognosis.

AB - This paper argues that the convention of allocating donated gametes on a 'first come, first served' basis should be replaced with an allocation system that takes into account more morally relevant criteria than waiting time. This conclusion was developed using an empirical bioethics methodology, which involved a study of the views of 18 staff members from seven U.K. fertility clinics, and 20 academics, policy-makers, representatives of patient groups, and other relevant professionals, on the allocation of donated sperm and eggs. Against these views, we consider some nuanced ways of including criteria in a points allocation system. We argue that such a system is more ethically robust than 'first come, first served', but we acknowledge that our results suggest that a points system will meet with resistance from those working in the field. We conclude that criteria such as a patient's age, potentially damaging substance use, and parental status should be used to allocate points and determine which patients receive treatment and in what order. These and other factors should be applied according to how they bear on considerations like child welfare, patient welfare, and the effectiveness of the proposed treatment. PMID- 29194682 TI - Impact of hepatitis C virus polymorphisms on direct-acting antiviral treatment efficacy: Regulatory analyses and perspectives. AB - : Several highly effective, interferon-free, direct-acting antiviral (DAA)-based regimens are available for the treatment of chronic hepatitis C virus (HCV) infection. Despite impressive efficacy overall, a small proportion of patients in registrational trials experienced treatment failure, which in some cases was associated with the detection of HCV resistance-associated substitutions (RASs) at baseline. In this article, we describe methods and key findings from independent regulatory analyses investigating the impact of baseline nonstructural (NS) 3 Q80K and NS5A RASs on the efficacy of current United States Food and Drug Administration (FDA)-approved regimens for patients with HCV genotype (GT) 1 or GT3 infection. These analyses focused on clinical trials that included patients who were previously naive to the DAA class(es) in their investigational regimen and characterized the impact of baseline RASs that were enriched in the viral population as natural or transmitted polymorphisms (i.e., not drug-selected RASs). We used a consistent approach to optimize comparability of results across different DAA regimens and patient populations, including the use of a 15% sensitivity cutoff for next-generation sequencing results and standardized lists of NS5A RASs. These analyses confirmed that detection of NS3 Q80K or NS5A baseline RASs was associated with reduced treatment efficacy for multiple DAA regimens, but their impact was often minimized with the use of an intensified treatment regimen, such as a longer treatment duration and/or addition of ribavirin. We discuss the drug resistance-related considerations that contributed to pretreatment resistance testing and treatment recommendations in drug labeling for FDA-approved DAA regimens. CONCLUSION: Independent regulatory analyses confirmed that baseline HCV RASs can reduce the efficacy of certain DAA based regimens in selected patient groups. However, highly effective treatment options are available for patients with or without baseline RASs. (Hepatology 2018;67:2430-2448). PMID- 29194683 TI - Leadless pacemaker extraction from a single-center perspective. AB - BACKGROUND: Leadless pacemaker can be considered as a technical revolution in cardiac pacing devices, with clear advantages over conventional pacemakers in overcoming all lead-related complications. However, the management of these devices once they reach the end of life (EOL) of the battery is still controversial. In the next years, there will be an increase in the need to define a clear strategy in the management of leadless PM once they reach their EOL. Safe extraction of these devices will define in a great manner this strategy METHODS: We performed the extraction of three functioning Nanostim leadless pacemaker prophylactically in two females and one male patients as part of the Nanostim battery depletion field action recommendation. All patients had a prior transesophageal 3D echocardiography to determine the device intracardiac mobility and the extent of possible endothelialization. For the extractions, we used the Nanostim Retrieval Catheter S1RSIN (St. Jude Medical, St. Paul, MN, USA), which is a proprietary catheter provided by the manufacturing company based on a lasso. RESULTS: Complete extraction of the devices was achieved in all patients using a relatively short fluoroscopic time (16, 19, and 12 minutes). CONCLUSIONS: The extraction of leadless pacemakers can be considered as a safe and feasible procedure using the tools provided by the manufacturer and designed for the extraction. However, a very low threshold must be maintained to avoid any risk to the patients. Our extraction time ranges are between 983 and 1,070 days, nevertheless it is necessary to gather more long-term data to assess the feasibility and safety of these procedures. PMID- 29194681 TI - A Population-based Study of Perinatal Infection Risk in Women with and without Systemic Lupus Erythematosus and their Infants. AB - BACKGROUND: Increased risk of adverse birth outcomes is well described in women with systemic lupus erythematosus (SLE), but risk of maternal or infant infection in the peripartum period has not been well studied. We conducted a population based cohort study of infection risk in women with and without SLE and their infants. METHODS: Linked birth-hospital discharge data identified 1297 deliveries to women with SLE and a 4:1 comparison cohort of deliveries to women without SLE in Washington State, 1987-2013. Maternal and infant infections during the first 30 days after delivery were identified. Relative risks (RR) and 95% confidence intervals (CI) were estimated. RESULTS: Women with SLE were 1.7 times more likely (95% CI 1.4, 2.0) to have an infection during the birth hospitalisation and more likely to receive antibiotics during labour (RR 1.3, 95% CI 1.1, 1.5), though there was no increased risk of chorioamnionitis in women with SLE. Infants of women with SLE had an increased risk for an infection during the birth hospitalisation (RR 2.2, 95% CI 1.3, 3.5), although the size of the difference was smaller when adjusted for gestational age (RR 1.4, 95% CI 0.9, 2.1). Risks of neonatal infection, sepsis, receipt of antibiotics, and admission to neonatal intensive care were also increased, and were also attenuated after adjustment for gestational age. CONCLUSIONS: Women with SLE have an increased risk of peripartum infections and antibiotic exposure. Their neonates have a greater likelihood of infection, much of which is attributable to preterm birth. PMID- 29194684 TI - Global microRNA expression profiling in the liver biopsies of hepatitis B virus infected patients suggests specific microRNA signatures for viral persistence and hepatocellular injury. AB - : Hepatitis B virus (HBV) can manipulate the microRNA (miRNA) regulatory networks in infected cells to create a permissive environment for viral replication, cellular injury, disease onset, and its progression. The aim of the present study was to understand the miRNA networks and their target genes in the liver of hepatitis B patients involved in HBV replication, liver injury, and liver fibrosis. We investigated differentially expressed miRNAs by microarray in liver biopsy samples from different stages of HBV infection and liver disease (immune tolerant [n = 8], acute viral hepatitis [n = 8], no fibrosis [n = 16], early [F1+F2, n = 19] or late [F3+F4, n = 14] fibrosis, and healthy controls [n = 7]). miRNA expression levels were analyzed by unsupervised principal component analysis and hierarchical clustering. Analysis of miRNA-mRNA regulatory networks identified 17 miRNAs and 18 target gene interactions with four distinct nodes, each representing a stage-specific gene regulation during disease progression. The immune-tolerant group showed elevated miR-199a-5p, miR-221-3p, and Let-7a-3p levels, which could target genes involved in innate immune response and viral replication. In the acute viral hepatitis group, miR-125b-5p and miR-3613-3p were up, whereas miR-940 was down, which might affect cell proliferation through the signal transducer and activator of transcription 3 pathway. In early fibrosis, miR-34b-3p, miR-1224-3p, and miR-1227-3p were up, while miR-499a-5p was down, which together possibly mediate chronic inflammation. In advanced fibrosis, miR 1, miR-10b-5p, miR-96-5p, miR-133b, and miR-671-5p were up, while miR-20b-5p and miR-455-3p were down, possibly allowing chronic disease progression. Interestingly, only 8 of 17 liver-specific miRNAs exhibited a similar expression pattern in patient sera. CONCLUSION: miRNA signatures identified in this study corroborate previous findings and provide fresh insight into the understanding of HBV-associated liver diseases which may be helpful in developing early-stage disease diagnostics and targeted therapeutics.

PMID- 29194686 TI - New insights into the role and mechanism of c-Jun-N-terminal kinase signaling in the pathobiology of liver diseases. AB - The c-Jun-N-terminal-kinase (JNK) family is highly conserved across species such as Drosophila, C. elegans, zebrafish and mammals, and plays a central role in hepatic physiologic and pathophysiologic responses. These responses range from cell death to cell proliferation and carcinogenesis, as well as metabolism and survival, depending on the specific context and duration of activation of the JNK signaling pathway. Recently, several investigators identified the key molecules in the JNK activation loop which include apoptosis signal-regulating kinase (ASK1) and SH3-domain binding protein 5 (Sab) and their involvement in acute or chronic liver disease models. Thus, regulating JNK activation through modulating the JNK activation loop may represent an important new strategy in the prevention and treatment of acute and chronic liver diseases. In this review, we will discuss the molecular pathophysiology of the JNK activation loop and its role in the pathogenesis of liver diseases. (Hepatology 2018;67:2013-2024). PMID- 29194687 TI - Serum-free complete medium, an alternative medium to mimic androgen deprivation in human prostate cancer cell line models. AB - BACKGROUND: Almost all men who present with advanced prostate cancer (CaP) and some men who fail therapy for clinically localized CaP are treated with androgen deprivation therapy (ADT). CaP cell lines are used to identify and characterize new agents for ADT or investigate mechanisms of ADT resistance. CaP cell lines are maintained in culture medium that contains fetal bovine serum, which contains testosterone (T). Androgen deprivation experiments are performed using media supplemented with androgen-free serum, such as charcoal stripped fetal bovine serum (CS-FBS). However, CS-FBS composition varies from batch-to-batch and variations may impact experimental reproducibility. Serum free media (SFM) may provide a better defined alternative to media supplemented with CS-FBS (CSM). METHODS: Cell growth of six human CaP cell lines was assessed using 3-(4,5 Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). Androgen levels were measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS). RESULTS: MTT assays showed 5 of 6 CaP cell lines grew after 6 days of culture in androgen- deprived SFM or CSM. LNCaP and VCaP growth was stimulated when cells were cultured in SFM or CSM supplemented with T. LNCaP, C4-2, LAPC-4, and VCaP cell growth was inhibited when cultured in SFM or CSM with T and bicalutamide. LC MS/MS data showed LAPC-4 cells produced similar DHT levels when cultured in T supplemented SFM or CSM. Dutasteride impaired T to DHT metabolism in LAPC-4. CONCLUSIONS: Media composition contributed to growth differences observed between CaP cells cultured in SFM or CSM. However, the differences in media composition did not impair CaP cell response to T-stimulated growth, bicalutamide growth inhibition, metabolism of T, or dutasteride efficiency. SFM can be used as a better defined alternative to CSM for androgen deprivation experiments. PMID- 29194688 TI - The genetic diversity and population structures of indigenous pig breeds in Zhejiang Province revealed by GGRS sequencing. AB - Chinese indigenous pigs in Zhejiang Province are well known for their high fecundity. In order to verify breed subdivision at the genomic level, we investigated genetic diversity and population structure of seven breeds and made comparisons with three Western pig breeds using next-generation sequencing data. Parameters obtained from allelic richness and proportion of polymorphic markers indicated that the genetic diversity of the Chinese indigenous pigs was higher than that of the Western pigs, with the highest and lowest values found in the Chaluand and the Landrace pigs respectively. Both neighbor-joining tree and principal components analysis could distinguish breeds from one another and structure analysis showed less differentiation among Western pigs than among the Chinese pigs. The average linkage disequilibrium decay over distance was significantly less in the Chinese pigs compared with the Western pigs, ranging from 188.2 to 280.6 kb for the Chinese pigs and 680.3 to 752.8 kb for the Western breeds and showing an average r2 threshold value of 0.3. Results obtained from high-density SNP comparison over the whole genome on genetic diversity and population structure were in agreement with the current breed classification of the pigs in Zhejiang Province. More importantly, the results presented here advances our current understanding of the genomic biology of Chinese indigenous pigs in Zhejiang Province and allows for implementation of conservation strategies in additional breeds.

AB - INTRODUCTION: In mechanically ventilated patients, nonvolitional assessment of quadriceps weakness using femoral-nerve stimulation (twitch force) while the leg rests on a right-angle trapezoid or dangles from the bed edge is impractical. Accordingly, we developed a knee-support apparatus for use in ventilated patients. METHODS: Ninety subjects (12 ventilated patients, 28 ambulatory patients, and 50 healthy subjects) were enrolled. Twitches with leg-dangling, trapezoid, and knee-support setups were compared. RESULTS: Knee-support twitches were similar to trapezoid twitches but smaller than leg-dangling twitches (P < 0.0001). Inter- and intraoperator agreement was high for knee-support twitches at 1 week and 1 month. In ventilated patients, knee-support twitches were smaller than in healthy subjects and ambulatory patients (P < 0.004). DISCUSSION: The new knee-support apparatus allows accurate recording of quadriceps twitches. The ease of use in ventilated patients and excellent inter- and intraoperator agreement suggest that this technique is suitable for cross-sectional and longitudinal studies in critically ill patients.

PMID- 29194690 TI - A carbon 21 steroidal metabolite from progestin, 20beta-hydroxy-5alpha dihydroprogesterone, stimulates the androgen receptor in prostate cancer cells. AB - BACKGROUND: Clarifying the mechanisms underlying prostate cancer (PC) progression and resistance to androgen deprivation therapy (ADT) is an urgent clinical issue. ADT influences steroidal metabolism in patients with PC and promotes the accumulation of carbon 21 steroids (C21s), such as progestin. Because the enzymes responsible for C21s metabolism are similar to those for androgen metabolism, PC cells may be able to metabolize C21s intracellularly. Therefore, there is a possibility that intracrine C21s are implicated in PC progression and resistance to ADT, and the influence of C21s on PC cells is yet to be elucidated. In the present study, we focused on 20beta-hydroxy-5alpha-dihydroprogesterone (20beta OHDHP), a C21s metabolized from progestin, and showed that 20beta-OHDHP is synthesized in PC cells and is able to directly stimulate the androgen receptor (AR). METHODS: LNCaP, VCaP, and DU145 cells, which express a mutant AR (mAR), wild-type AR (wAR), and glucocorticoid receptor (GR), respectively, were incubated in the presence of several agents. After incubation, cell growth was determined by the MTS assay. PSA levels were determined by an enzyme immunoassay, and C21s and androgen levels were measured using liquid chromatography-mass spectrometry. Gene expression was analyzed by quantitative real-time polymerase chain reaction, and steroidal-receptor-related signaling was determined by a reporter assay. RESULTS: We affirmed that 20beta-OHDHP was synthesized from pregnenolone intracellularly in LNCaP and VCaP cells, and 20beta-OHDHP significantly promoted the growth of both cell lines without androgen conversion. 20beta-OHDHP directly stimulated both mAR and wAR. The presence of 20beta-OHDHP was sufficient for the proliferation and survival of LNCaP or VCaP cells, and 20beta-OHDHP promoted cell growth even in the presence of abiraterone. Using DU145 cells, we affirmed that 20beta-OHDHP did not stimulate GR, which has a potential to bypass AR signaling in PC cells promote PC cell growth. CONCLUSIONS: Under ADT, 20beta-OHDHP synthesized intracellularly from accumulated progestin in PC cells may accelerate cell growth via stimulation of both wAR and mAR. This pathway may represent an interesting candidate for targeted therapy. PMID- 29194692 TI - From Private Practice to Academia: Integrating social and political advocacy into every MFT Identity. AB - While advocacy was essential to establishing the field of marriage and family therapy, at present a social and political advocacy skill set is lacking for the typical marriage and family therapist (MFT). This article reviews the importance of being active in social and political advocacy and highlights the attributes of MFTs' professional identity that uniquely position us for success in these areas. Other mental health fields' pedagogical approaches to training and education are explored, and recommendations are made for how MFTs can begin to increase their competency in advocacy. Ideas for incorporating advocacy into a professional identity are presented for MFTs at every level of professional experience. Finally, the concept self-of-the-advocate is introduced and discussed. PMID- 29194691 TI - Mediterranean diet after prostate cancer diagnosis and urinary and sexual functioning: The health professionals follow-up study. AB - BACKGROUND: Men with prostate cancer often experience urinary and sexual dysfunction after treatment. Previous studies have demonstrated a relationship between dietary factors and these symptoms among men with diabetes or metabolic syndrome. However, there are limited data on whether diet after prostate cancer diagnosis, including a Mediterranean dietary pattern, affects urinary and sexual function among prostate cancer survivors. METHODS: Men diagnosed with non metastatic prostate cancer in the Health Professionals Follow-up Study (n = 2960) from 1986 to 2012 were prospectively followed for a median of 8.3 years after treatment. Participants completed validated dietary questionnaires every 4 years and a health-related quality of life assessment in 2010 or 2012. We used generalized linear models to examine associations between post-diagnosis Mediterranean Diet Score (including individual score components and dietary fat subtypes) and quality of life domains (sexual functioning, urinary irritation/obstruction, urinary incontinence) assessed using the Expanded Prostate Cancer Index Composite Short Form (score 0-100; higher scores indicate better function). RESULTS: No statistically significant relationships were observed between the Mediterranean Diet Score after prostate cancer diagnosis and urinary or sexual function. However, the associations did vary depending on pre diagnosis urinary and sexual dysfunction for urinary irritation/obstruction and sexual function scores, respectively (P-interactions < 0.0001). Men with higher post-diagnosis vegetable intake reported higher urinary incontinence scores (72 vs 76 comparing lowest to highest quintile; P-trend = 0.003). Similarly, higher vegetable intake and lower polyunsaturated fat intake were associated with higher urinary irritation/obstruction scores (vegetable: 80 vs 84 comparing lowest to highest quintile, P-trend = 0.01; polyunsaturated fat: 84 vs 78 comparing lowest to highest quintile, P-trend = 0.005), however these associations were observed only among men with urinary symptoms prior to their prostate cancer diagnosis. CONCLUSIONS: Among men with prostate cancer, diet intake after diagnosis was not significantly associated with urinary or sexual function, although some relationships appeared to differ among men with and without symptoms prior to their prostate cancer diagnosis. Higher vegetable intake and lower polyunsaturated fat intake after prostate cancer diagnosis may be associated with better urinary function. However, this analysis was exploratory, and further research is needed to better delineate these relationships and guide dietary recommendations for men with prostate cancer. PMID- 29194693 TI - The Development and Implementation of a Multi-Couple Therapy Model with Torture Survivors in the Democratic Republic of the Congo. AB - In this article, we present development and feasibility of implementation of a multi-couple group for use with torture-surviving couples. The model was developed in the Democratic Republic of the Congo in a community that experienced widespread torture during the wars from 1998 to 2004. The Torture-Surviving Couple Group model is a short-term intervention designed to use few human resources to address relational difficulties resulting from exposure to traumatic stressors. The model was guided by critical and feminist epistemologies and employed an ecological lens to incorporate neurobiology and attachment processes along with narrative therapy techniques. An existing multi-couple group model for addressing violence (Stith, Rosen, McCollum, & Thomsen, ), and a stage model for healing trauma (Herman, ) also informed the structural development of the Torture Surviving Couple Group model. Couple groups were conducted using a 10-session program with 13 couples who met weekly. Session themes were incorporated into four phases emphasizing: (a) preparation; (b) safety and stabilization; (c) processing the relationship effects of trauma and grief; and (d) reintegration and rebuilding couple and family life. Couples reported and showed remarkable progress in their relationships after participating in the groups. Clinical and research implications and discussed along with the feasibility of developing and testing the model in a post-conflict low income setting. PMID- 29194695 TI - A Grounded Theory Study of How Couples Desist from Intimate Partner Violence. AB - Intimate partner violence is a common and damaging experience for many couples, and therapists struggle to address it adequately (Johnson, 2008). Despite its negative effects, many violent couples stay together, with some stopping their violent behaviors. Unfortunately, we know little about the systemic factors affecting violence desistance. This study used grounded theory methods to analyze the process of desistance in formerly violent couples. A model of desistance consisting of three categories was developed, which for most couples included a (a) Turning Point, (b) Decision to Change, and (c) Doing Things Differently. Therapists are encouraged to use the model to better understand the varied and systemic nature of violence and desistance, and to make more sophisticated decisions about referral and treatment.

PMID- 29194696 TI - Family Focused Care for Refugees and Displaced Populations: Global Opportunities for Family Therapists. AB - Recent global crises have created a significant increase in the number of people leaving their countries. Distress experienced by these refugees often leads to posttraumatic stress disorder and depression and can also result in psychotic disorders, substance abuse, and interpersonal violence. The World Health Organization leads the organizing of refugee services as part of a larger initiative to provide mental health services to citizens in low- and middle income countries. The World Health Organization has identified challenges in providing care, including a provider shortage, issues with how refugees access and receive care and a lack of uniformity in mental health services. By applying the values and systemic orientation of the profession, family therapists can address some of the challenges in treating mental health concerns of these at risk populations. PMID- 29194697 TI - Observed Interactions in Families of Adolescent Suicide Attempters. AB - Family interactions of 71 adolescents hospitalized following a suicide attempt were compared with those of 29 psychiatric controls, using observational methods and a 2-year prospective, longitudinal design. Parent-adolescent dyadic interactions were coded for emotional validation and invalidation, and problem solving constructiveness. There were no between-group differences for parents. However, adolescents who had attempted suicide displayed more emotional invalidation than controls. Within the suicide attempt group, maternal constructive problem solving predicted greater declines in youth suicide ideation, and a similar trend was observed for fathers. Adolescents who displayed more unconstructive problem solving with fathers were more likely to reattempt suicide during the follow up. PMID- 29194698 TI - Impaired Rivaroxaban Clearance in Mild Renal Insufficiency With Verapamil Coadministration: Potential Implications for Bleeding Risk and Dose Selection. AB - Pharmacokinetics and antithrombotic effects of the Factor Xa inhibitor rivaroxaban were studied in subjects with mild renal insufficiency concurrently taking the P-glycoprotein and moderate CYP3A inhibitor verapamil, a drug commonly administered to patients with hypertension, ischemic heart disease, or atrial fibrillation. Age-matched controls with normal renal function were studied concurrently. Subjects' overall mean age was 59 years. Mean creatinine clearance values in the 2 groups were 105 and 71 mL/min. After single 20-mg oral doses, rivaroxaban area under the curve (AUC) was increased by a factor of 1.11 (ratio of geometric means [RGM]) in mild renal insufficiency compared to controls. Verapamil coadministration independently increased AUC to the same extent in both the mild renal insufficiency and control groups (RGM, 1.39 and 1.43). Concurrent mild renal insufficiency and verapamil produced additive inhibition compared to controls without verapamil (RGM, 1.58). Prothrombin time (PT) prolongation and Factor Xa inhibition tracked plasma rivaroxaban, and were enhanced by verapamil. Concentration-response relationships for PT (linear) and Factor Xa inhibition (hyperbolic) were unaffected by renal function or verapamil. The absolute and relative increases in rivaroxaban AUC caused by verapamil in mild renal insufficiency subjects are potentially associated with an increased bleeding risk. Modification of recommended dosage may be required in this combination of circumstances to reduce risk to patients. PMID- 29194699 TI - Ultrasonographic Findings of 1385 Adrenal Masses: A Retrospective Study of 1319 Benign and 66 Malignant Masses. AB - OBJECTIVES: To evaluate the features of adrenal masses on ultrasonography and correlate the findings with the pathologic diagnoses to help distinguish benign from malignant adrenal lesions. METHODS: Ultrasonography was performed in 1363 patients with adrenal lesions. The following ultrasonographic parameters were recorded: size, shape, margin, echogenicity, echo texture, cystic necrosis, calcifications, and blood supply. The sensitivity and specificity of aggressive features for predicting malignancy were calculated. RESULTS: Of 1385 adrenal lesions, 66 (4.8%) were malignant: 33 malignant pheochromocytomas, 20 adrenal cortical carcinomas, 10 metastases, 2 leiomyosarcomas, and 1 primitive neuroectodermal tumor. The remaining 1319 (95.2%) lesions were benign: 832 adenomas, 182 pheochromocytomas, 153 nodular adrenal hyperplasia, 54 myelolipomas, 42 cysts, 23 ganglioneuromas, 10 schwannomas, 8 cortical tumor eosinophils, 4 teratomas, 4 tuberculosis, 4 primary pigmented nodular adrenocortical disease, and 3 Castleman disease. Most of the tumors were regular and hypoechoic. The malignant lesions were significantly larger than the benign lesions (mean +/- SD, 6.3 +/- 2.4 versus 4.6 +/- 1.7 cm; P < .01). Significant differences between malignant and benign tumors were observed when comparing the shape, margins, echo texture and vascularization of the analyzed lesions (P < .01). An irregular shape, poor definition of margins, heterogeneous echo texture, and vascularization indicated malignancy, with sensitivity and specificity of 45.5% and 97.0%, 34.8% and 99.2%, 92.4% and 97.3%, and 15.2% and 97.5%, respectively. CONCLUSIONS: Ultrasonography could be an effective diagnostic supplementary tool for adrenal tumors. A large size, irregular shape, poorly defined margins, heterogeneous echo texture, and vascularization of adrenal lesions could be effective indicators of malignancy. PMID- 29194700 TI - Metastatic laryngeal large cell neuroendocrine carcinoma: A rare case of presentation and extreme tumor burden. AB - Large cell neuroendocrine carcinoma (LCNEC) of the larynx is an aggressive form of neuroendocrine carcinoma that affects smokers at an average age of 60 years. LCNEC is characterized by large cells with round to ovoid nuclei distributed in a trabecular or nested growth pattern. Previously, laryngeal LCNEC and atypical carcinoid tumors were considered identical; however, laryngeal LCNEC has been shown to have higher mitotic rates and worse prognosis, which has led to laryngeal LCNEC's being separated from atypical carcinoid and classified as a poorly differentiated neuroendocrine carcinoma in the most recent World Health Organization classification. We present a case of a 56-year-old female who presented with painful subcutaneous skin lesions that were diagnosed as metastatic carcinoma at an outside facility. Subsequent workup revealed a primary epiglottic lesion. Over the next 4 years, she continued to develop over 100 similar subcutaneous nodules. Additional workup confirmed neuroendocrine differentiation, thus clarifying the diagnosis of metastatic LCNEC. Review of literature has revealed only 1 reported case of LCNEC with skin metastasis. This is the first reported case in which skin metastasis was the initial presenting symptom; moreover, our case is unique with regard to the heavy metastatic burden to the skin. PMID- 29194701 TI - Repeatability of Female Midurethral Measurement Using High-Frequency 3 Dimensional Transvaginal Ultrasonography. AB - OBJECTIVES: Imaging assessment of the female urethra is critical for diagnosis and treatment of urinary incontinence. High-frequency 3-dimensional (3D) transvaginal ultrasonography (TVUS) is a novel technique for evaluating the female urethra. The aim of this study was to test the repeatability of 3D TVUS between examiners without prior experience with TVUS. METHODS: Fifty women underwent 3D TVUS. Two examiners without prior experience analyzed the urethral volumes and measured the urethral parameters. Two-dimensional (2D) parameters included urethral sphincter length and urethral sphincter thickness; 3D parameters included urethral sphincter volume, midurethral complex volume, and inner core volume. One of the examiners repeated the evaluations 1 month later. Subsequently, the measurements were compared. RESULTS: The mean age of the patients +/- SD was 34.1 +/- 8.1 (range, 23-55) years; the mean height, weight, and body mass index were 160.44 +/- 5.12 (range, 150-173) cm, 61.80 +/- 13.64 (range, 45-110) kg, and 23.98 +/- 4.91 (range, 17.53-39.92) kg/m2 , respectively. The results of our study showed excellent to good intraobserver repeatability (intraclass correlation coefficient [ICC], 0.75-0.87) for the evaluations of all parameters but urethral sphincter length (moderate ICC, 0.53), whereas they showed good to moderate interobserver repeatability (ICC, 0.44-0.77) for all parameters. The repeatability of 3D volumes (ICC, 0.59-0.87) tended to be better than that of 2D parameters (ICC, 0.44-0.76). CONCLUSIONS: The intraobserver and interobserver repeatability of high-frequency 3D TVUS measurements of the female urethra was excellent to moderate between examiners without previous experience. The repeatability of 3D measurements tended to be better than that of 2D parameters. PMID- 29194702 TI - The role of TMPRSS6 and HFE variants in iron deficiency anemia in celiac disease. AB - We investigated the role of HFE C282Y, H63D, and TMPRSS6 A736V variants in the pathogenesis of iron deficiency anemia (IDA) in celiac disease (CD) patients, at diagnosis and after 1 year of gluten-free diet (GFD). Demographic and clinical features were prospectively recorded for all CD patients between 2013 and 2017. C282Y, H63D, and A736V variants were evaluated for CD patients and controls. Finally, 505 consecutive CD patients and 539 age-matched control subjects were enrolled. At diagnosis, 229 CD subjects had IDA (45.3%), with a subgroup of anemic patients (45.4%) presented persistent IDA at follow-up. C282Y allele frequency was significantly increased in CD compared with controls (1.1% vs 0.2%, P = .001), whereas H63D and A736V allele frequencies were similar among patients and controls (P = .92 and .84, respectively). At diagnosis, C282Y variant in anemic CD patients was significantly increased compared to nonanemic group (2% and 0.5%, P = .04). At follow-up, A736V was significantly increased in IDA persistent than in IDA not persistent (57.7% vs 35.2%, P < .0001). CD patients with H63D mutation showed higher Hb, MCV, serum iron, and ferritin levels than subjects without HFE mutations. Decreased hepcidin values were observed in anemic compared to nonanemic subjects at follow-up (1.22 +/- 1.14 vs 2.08 +/- 2.15, P < .001). This study suggests a protective role of HFE in IDA CD patients and confirms the role of TMPRSS6 in predicting oral iron response modulating hepcidin action on iron absorption. Iron supplementation therapeutic management in CD could depend on TMPRSS6 genotype that could predict persistent IDA despite iron supplementation and GFD. PMID- 29194703 TI - Development and psychometric evaluation of a rapid intimate partner violence perpetration screening tool. AB - Current methods of identifying intimate partner violence (IPV) perpetration rely upon lengthy screening instruments, partner injury, and legal involvement. There exist no viable, brief screening tools to facilitate the rapid and early identification of IPV perpetration. The development of a brief IPV screening tool would reduce participant burden and compensation in research as well as aid in self-identification and appropriate consultation for treatment. Three samples were recruited and administered an IPV assessment measure. Receiver Operating Characteristic (ROC) curve analyses were used to determine a critical subset of items that could be rapidly administered and used to accurately detect physical IPV perpetrators. A set of four items emerged that were capable of differentiating between partner violent and nonviolent participants in Samples 1 (the Area Under the ROC Curve (AUC) = .95, SE = .02), 2 (AUC = .98, SE =.01), and 3 (AUC = .94, SE = .04). Internal consistency of the screening items was acceptable across samples and the scores on the screening tool were significantly associated in the expected direction with all assessed risk factors for IPV. Initial evaluation of the rapid IPV perpetration screening tool suggests that it may help satisfy the growing need to quickly determine research eligibility and to help college students self-identify risk, offering objective data upon which to base the decision for follow-up consultation. PMID- 29194704 TI - Social play among juvenile wild Japanese macaques (Macaca fuscata) strengthens their social bonds. AB - Social play and grooming are typical affiliative interactions for many primate species, and are thought to have similar biological functions. However, grooming increases with age, whereas social play decreases. We proposed the hypothesis that both social grooming and social play in juveniles strengthen their social bonds in daily activities. We carried out field research on the social relationships among juvenile wild Japanese macaques in a troop in Kinkazan, Miyagi Prefecture, Japan, from fall 2007 to spring 2008 to investigate this hypothesis. We evaluated three relationships among juveniles, play indices (PI), grooming indices (GI), and 3-m-proximity indices (3mI) of each dyad (i.e., interacting pair), and compared these social networks based on the matrices of the indices. The play and grooming networks were correlated with the association network throughout the two research periods. The multiple network level measurements of the play network, but not the grooming network, resembled those of the association network. Using a causal step approach, we showed that social play and grooming interactions in fall seem to predict associations in the following spring, controlling for the PI and GI matrix in spring, respectively. Social play and grooming for each juvenile were negatively correlated. The results partially support our predictions; therefore, the hypothesis that the biological function of social play among immature Japanese macaques is to strengthen their social bonds in the near future and develop their social life appears to be correct. For juvenile macaques, social play, rather than grooming, functions as an important social mechanism to strengthen affiliative relationships. PMID- 29194705 TI - Reply.

AB - La Reunion Island has been the scene of unusually large epidemics of dengue and chikungunya viruses with Aedes albopictus as the sole vector. After experimental oral infection, Ae. albopictus from La Reunion Island can disseminate both dengue and chikungunya viruses but not the Asian genotype of Zika virus, suggesting a strong midgut barrier to dissemination. Autochthonous transmission of the Asian genotype of Zika virus is improbable on La Reunion Island.

PMID- 29194708 TI - Metastatic serous carcinoma presenting as inflammatory carcinoma over the breast Report of two cases and literature review. AB - Non-mammary metastases involving breast are rare and most commonly involve the breast parenchyma. Infrequently, metastasis from an extramammary primary site presents as inflammatory carcinoma over the breast. Diagnosis of such lesions can be challenging, especially in patients with coexisting primary breast carcinoma. Few such cases have been described in literature; however, none of the previously reported cases had a prior history of primary breast carcinoma. We present 2 patients with history of breast carcinoma and serous carcinoma of ovarian/peritoneal origin that presented with inflammatory carcinoma over the breast. Biopsies from breast tissue showed atypical cells in the dermis forming cords and papillary structures. Histopathologic differential diagnosis included infiltrating ductal carcinoma of breast origin and metastatic serous carcinoma. Immunohistochemical studies showed that the tumor cells were positive for markers of ovarian origin such as PAX-8 and CA-125 and negative for breast markers such as GATA-3, thus supporting the diagnosis. In summary, we describe the unusual presentation of metastatic serous carcinoma as inflammatory carcinoma over breast and discuss the diagnostic challenges in patients with coexisting primary breast and ovarian malignancies. We also review the morphologic features of tumors of breast and ovarian origin and the immunohistochemical stains to differentiate these 2 entities. PMID- 29194709 TI - Low-grade spindle cell proliferation in clear cell renal cell carcinoma is unlikely to be an initial step in sarcomatoid differentiation. AB - AIMS: Spindle cell proliferation within clear cell renal cell carcinoma (ccRCC) is usually considered as a sarcomatoid differentiation. Low-grade spindle cell proliferation (LG-SCP) in ccRCC was first described in 2001. This phenomenon is not common and can pose diagnostic challenges, particularly in core biopsies. The aim of this study was to describe morphological, immunohistochemical and molecular characteristics of ccRCCs with LG-SCP. METHODS AND RESULTS: Eleven cases of ccRCC with LG-SCP were retrieved from approximately 21 000 renal tumours in our registry. Ten cases of conventional ccRCC and 10 cases of typical sarcomatoid ccRCC were included as control groups. Morphological and immunohistochemical characteristics of epithelial-mesenchymal transition (EMT) were analysed. Von Hippel-Lindau syndrome gene abnormalities were also analysed using molecular genetics. Among ccRCC with LG-SCP cases, there were five males and five females (clinical information was not available in one case) with a median age of 67 years (mean: 68.5, range: 60-81 years). Average tumour size was 7.1 cm (median:7.5, range:1.7-12 cm). Follow-up data were available in nine cases (mean: 44.78 months), with no aggressive behaviour seen. On average, LG-SCP areas constituted 5-80% of tumour volume (mean: 32.3%). Necrotic/regressed areas were seen in all cases ranging from 5% to 30%. LG-SCP was clearly epithelial, with no mitoses or any evidence of mesenchymal differentiation. Immunohistochemical profile of LG-SCP was consistent with 'conventional' ccRCC. Compared with sarcomatoid ccRCC, some EMT markers showed alteration in LG-SCP, including lower expression of N-cadherin and Zeb1 as well as higher expression of E-cadherin. However, there were no significant differences in EMT markers between LG-SCP and conventional ccRCC. Abnormalities in VHL (mutations, LOH3p) were found in six of 11 cases. CONCLUSIONS: Our findings showed that LG-SCP in ccRCC have comparable immunohistochemical and molecular characteristics to those seen in 'conventional' ccRCC. Further, immunohistochemical analysis of EMT markers showed that LG-SCP did not differ from 'conventional' ccRCC. We believe that LG-SCP is a part of morphological heterogeneity in ccRCCs and that they may not represent an initial stage of sarcomatoid differentiation. This is supported further by the fact that ccRCC with LG-SCP did not display more aggressive behaviour than 'conventional' ccRCC. PMID- 29194710 TI - Links between the discovery of primates and anatomical comparisons with humans, the chain of being, our place in nature, and racism. AB - I focus on the crucial links between the discovery of nonhuman primates by Westerners, discussions on our place in nature, the chain of being, racism, and the history of primate comparative anatomy and of so-called "anatomical human racial studies." Strikingly, for more than a millennium humans knew more about the internal anatomy of a single monkey species than about that of their own bodies. This is because Galen used monkeys to infer human anatomy, in line with the human-animal continuity implied by the Greek notion of scala naturae. With the rise of Christianity, nonhuman primates were increasingly seen in a negative way. A more positive view emerged in the 14th century when nonhuman primates were directly studied/seen by Europeans, culminating in Tyson's 1699 work showing that chimps share more gross anatomical similarities with humans than with monkeys. However, the discomfort caused by this human-chimp similarity then led to a new idea of animal-human discontinuity, now related not to anatomy but to "civilization": between Europeans vs. non-Europeans + other primates. Moreover, Linnaeus' Systema Naturae and the emergence of "anatomical racial studies" influenced by Camper's craniology then led to even more extreme ideas, such as the notion that Europeans were both mentally and morphologically "ideal." Unfortunately the biased and often incorrect "results" of such studies, combined with ideas based on Darwin's "struggle for survival", became crucial in propaganda that lead to the rise of eugenics in the end of the 19th/first half of 20th centuries and that culminated in Nazism. Since the 1950s there has been an emphasis on the continuity/unity between all human groups and other primates, in great part influenced by what happened during World War 2. Reviews such as this one are, therefore, particularly necessary to illuminate and guard against attitudes against "the Other" and racist ideologies that are re-emerging in modern political discourse across the globe. PMID- 29194711 TI - Institutional decision to adopt Y90 as primary treatment for hepatocellular carcinoma informed by a 1,000-patient 15-year experience. AB - : Yttrium-90 transarterial radioembolization (TARE) is a locoregional therapy (LRT) for hepatocellular carcinoma (HCC). In this study, we present overall survival (OS) outcomes in a 1,000-patient cohort acquired over a 15-year period. Between December 1, 2003 and March 31, 2017, 1,000 patients with HCC were treated with TARE as part of a prospective cohort study. A comprehensive review of toxicity and survival outcomes was performed. Outcomes were stratified by baseline Child-Pugh (CP) class, United Network for Organ Sharing (UNOS), and Barcelona Clinic Liver Cancer (BCLC) staging systems. Albumin and bilirubin laboratory toxicities were compared to baseline. OS outcomes were reported using censoring and intention-to-treat methodologies. All treatments were outpatient, with a median one treatment per patient. Five hundred six (51%) were CP A, 450 (45%) CP B, and 44 (4%) CP C. Two hundred sixty-three (26%) patients were BCLC A, 152 (15%) B, 541 (54%) C, and 44 (4%) D. Three hundred sixty-eight (37%) were UNOS T1/T2, 169 (17%) T3, 147 (15%) T4a, 223 (22%) T4b, and 93 (9%) N/M. In CP A patients, censored OS for BCLC A was 47.3 (confidence interval [CI], 39.5-80.3) months, BCLC B 25.0 (CI, 17.3-30.5) months, and BCLC C 15.0 (CI, 13.8-17.7) months. In CP B patients, censored OS for BCLC A was 27 (CI, 21-30.2) months, BCLC B 15.0 (CI, 12.3-19.0) months, and BCLC C 8.0 (CI, 6.8-9.5) months. Forty nine (5%) and 110 (11%) patients developed grade 3/4 albumin and bilirubin toxicities, respectively. CONCLUSION: Based on our experience with 1,000 patients over 15 years, we have made a decision to adopt TARE as the first-line transarterial LRT for patients with HCC. Our decision was informed by prospective data and incrementally reported demonstrating outcomes stratified by BCLC, applied as either neoadjuvant or definitive treatment. (Hepatology 2017).

PMID- 29194713 TI - Intraspecific variation in the domestic cat bony labyrinth revealed by different measurement techniques. AB - The knowledge of intraspecific variation is important to make assumptions on an interspecific level. To study intraspecific variation in the bony labyrinth morphology of the domestic cat, eleven specimens of Felis silvestris catus and two additional subspecies (F. s. lybica, F. s. ornata) were investigated. The sample comprises skulls of adult males and females, as well as juvenile cats. Each bony labyrinth endocast was virtually reconstructed based on uCT scans. To estimate the radius of curvature of each inner ear semicircular canal, three different approaches were tested. The comparison of the different methods resulted in different absolute values for the measured radii. The assumed best structure to precisely characterize the size of a semicircular canal is the inner perimeter. Within the tested sample, the anterior semicircular canal is always the largest, while the posterior semicircular canal is the second largest and the lateral semicircular canal the smallest in most cases. The coefficient of variation lies below 10% for all bony labyrinth measurements within the sample. The inner perimeter values of each semicircular canal are similar within all investigated specimens, even though the skull length of adult cats is twice as long as that of juvenile cats. Thus, inner ear biometry of the domestic cat seems stable throughout growth series and can therefore be used for systematic and ecological studies and the inclusion of juvenile individuals is reasonable. It is noteworthy that the inner perimeter values of the semicircular canals do not vary as much as the values of the angles spanned between the three canals within the sample. The inner ear within the cat skull is oriented about 25 degrees to 31 degrees to the palate (angle between the plane anchored to the lateral semicircular canals (SC) and the plane anchored to the palate). The cochlea coils between 3.00 and 3.25 turns in the investigated sample. PMID- 29194714 TI - Survival following salvage therapy for primary refractory peripheral T-cell lymphomas (PTCL). AB - Optimal salvage therapy for primary refractory peripheral T-cell lymphomas (PTCL) and the role of hematopoietic stem cell transplant (SCT) remain poorly defined. We conducted a retrospective review of clinical outcomes and prognostic factors in a single-center cohort of 93 patients with primary refractory PTCL, defined as progression during first-line therapy or relapse within 6 months of its completion. Clinical outcomes were poor in this population, with median event free survival (EFS) of 3.5 months, median overall survival (OS) of 9.1 months, and 34% 3-year survival. Outcomes were comparable in patients who progressed through first-line therapy and patients who achieved CR/PR and subsequently relapsed within 6 months. A majority exhibited high-risk features and had intermediate to high risk IPI, which correlated with inferior outcomes. There was no difference in outcomes between patients who received single-agent salvage regimens and patients who underwent traditional, multi-agent salvage regimens. Thus, participation in well-designed clinical trials should be encouraged in this population. Additionally, there may be a trend toward improved EFS and OS in patients who underwent autologous or allogeneic SCT compared to patients who achieved CR or PR but were not transplanted. PMID- 29194715 TI - Estimating the DINA model parameters using the No-U-Turn Sampler. AB - The deterministic inputs, noisy, "and" gate (DINA) model is a popular cognitive diagnosis model (CDM) in psychology and psychometrics used to identify test takers' profiles with respect to a set of latent attributes or skills. In this work, we propose an estimation method for the DINA model with the No-U-Turn Sampler (NUTS) algorithm, an extension to Hamiltonian Monte Carlo (HMC) method. We conduct a simulation study in order to evaluate the parameter recovery and efficiency of this new Markov chain Monte Carlo method and to compare it with two other Bayesian methods, the Metropolis Hastings and Gibbs sampling algorithms, and with a frequentist method, using the Expectation-Maximization (EM) algorithm. The results indicated that NUTS algorithm employed in the DINA model properly recovers all parameters and is accurate for all simulated scenarios. We apply this methodology in the mental health area in order to develop a new method of classification for respondents to the Beck Depression Inventory. The implementation of this method for the DINA model applied to other psychological tests has the potential to improve the medical diagnostic process.

AB - OBJECTIVES: Ultrasound (US) lung comets are often observed in patients with interstitial lung disease or congestive heart failure, but few studies have explored the clinical importance of US lung comets in patients with the former condition. We explored whether the US lung comet number could be used to assess the severity of interstitial pneumonia. METHODS: Forty stable patients with interstitial pneumonia were examined. Lung comets evident on transthoracic US imaging in 12 selected regions of the posterior chest wall were analyzed. We defined lung comets accompanied by thickened and irregular pleural lines as interstitial US lung comets; these predominated in patients with interstitial pneumonia. The total number of interstitial US lung comets was correlated with the data from chest high-resolution computed tomography, pulmonary function tests, serologic tests, and the 6-minute walk test. RESULTS: The 40 patients included 16 with idiopathic pulmonary fibrosis and 24 with nonspecific interstitial pneumonia. Thirty-four patients had interstitial US lung comets, which were more common in the lower than the upper lung area. Good correlations were evident between the lung comet number and the extent of the reticular pattern on chest high-resolution computed tomography (r = 0.710; P < .01), predicted forced vital capacity (r = -0.614; P < .01), and lung diffusion capacity for carbon monoxide (r = -0.577; P < .01). Notably, the lung comet number had a strong negative correlation with the percutaneous oxygen saturation level after the 6-minute walk test (r = -0.751; P < .01). CONCLUSIONS: The number of interstitial US lung comets evident on transthoracic US imaging may be a valuable marker of disease severity in patients with interstitial pneumonia.

PMID- 29194718 TI - Prediction of olanzapine exposure in individual patients using physiologically based pharmacokinetic modelling and simulation. AB - AIM: The aim of the present study was to predict olanzapine (OLZ) exposure in individual patients using physiologically based pharmacokinetic modelling and simulation (PBPK M&S). METHODS: A 'bottom-up' PBPK model for OLZ was constructed in Simcyp(r) (V14.1) and validated against pharmacokinetic studies and data from therapeutic drug monitoring (TDM). The physiological, demographic and genetic attributes of the 'healthy volunteer population' file in Simcyp(r) were then individualized to create 'virtual twins' of 14 patients. The predicted systemic exposure of OLZ in virtual twins was compared with measured concentration in corresponding patients. Predicted exposures were used to calculate a hypothetical decrease in exposure variability after OLZ dose adjustment. RESULTS: The pharmacokinetic parameters of OLZ from single-dose studies were accurately predicted in healthy Caucasians [mean-fold errors (MFEs) ranged from 0.68 to 1.14], healthy Chinese (MFEs 0.82 to 1.18) and geriatric Caucasians (MFEs 0.55 to 1.30). Cumulative frequency plots of trough OLZ concentration were comparable between the virtual population and patients in a TDM database. After creating virtual twins in Simcyp(r), the R2 values for predicted vs. observed trough OLZ concentrations were 0.833 for the full cohort of 14 patients and 0.884 for the 7 patients who had additional cytochrome P450 2C8 genotyping. The variability in OLZ exposure following hypothetical dose adjustment guided by PBPK M&S was twofold lower compared with a fixed-dose regimen - coefficient of variation values were 0.18 and 0.37, respectively. CONCLUSIONS: Olanzapine exposure in individual patients was predicted using PBPK M&S. Repurposing of available PBPK M&S platforms is an option for model-informed precision dosing and requires further study to examine clinical potential. PMID- 29194721 TI - Initial experiences with NAM-assisted primary repair of the BCLP deformity. AB - BACKGROUND: Primary surgical repair of the bilateral cleft lip and palate (BCLP) deformity is challenging. Infant Orthopedic (IO) procedures are often used to assist surgical reconstruction of normal anatomy. Nasoalveolar molding (NAM) is a presurgical infant orthopedic procedure that attempts to reduce the cleft nasal deformity, in addition to the lip and alveolus, leading to an esthetic primary surgical repair. OBJECTIVE: NAM provides the surgical team with a better foundation for an easier and more esthetic single stage repair at the level of nose in addition to the lip and alveolus. METHOD: Infant nasal cartilages are amenable to correction with NAM in the first few weeks of infancy when they retain their plasticity. NAM-assisted surgical repair of a complete BCLP infant is discussed. Postoperatively nasal stents were used to retain results and minimize relapse. RESULTS: NAM helped correct premaxillary deviation and protrusion, reduce alveolar cleft width and improve the nasal morphology prior to surgery in the BCLP infant. CONCLUSIONS: NAM helped reduce the severity of the cleft deformity in the BCLP infant and facilitated an easier and esthetic single stage primary surgical repair. PMID- 29194722 TI - The RNA genome of hepatitis E virus robustly triggers an antiviral interferon response. AB - : The outcomes of hepatitis E virus (HEV) infection are diverse, ranging from asymptomatic carrier, self-limiting acute infection, and fulminant hepatitis to persistent infection. This is closely associated with the immunological status of the host. This study aimed to understand the innate cellular immunity as the first-line defense mechanism in response to HEV infection. Phosphorylation of signal transducer and activator of transcription 1, a hallmark of the activation of antiviral interferon (IFN) response, was observed in the liver tissues of the majority of HEV-infected patients but not in the liver of uninfected individuals. In cultured cell lines and primary liver organoids, we found that HEV RNA genome potently induced IFN production and antiviral response. This mechanism is conserved among different HEV strains, including genotypes 1, 3, and 7 as tested. Interestingly, single-stranded HEV RNA is sufficient to trigger the antiviral response, without the requirement of viral RNA synthesis and the generation of an RNA replicative form or replicative intermediate. Surprisingly, the m7 G cap and poly A tail are not required, although both are key features of the HEV genome. Mechanistically, this antiviral response occurs in a retinoic acid-inducible gene I-independent, melanoma differentiation-associated protein 5-independent, mitochondrial antiviral signaling protein-independent, and beta-catenin independent but IRF3-dependent and IRF7-dependent manner. Furthermore, the integrity of the Janus kinase-signal transducer and activator of transcription pathway is essentially required. CONCLUSION: HEV infection elicits an active IFN related antiviral response in vitro and in patients, triggered by the viral RNA and mediated by IFN regulatory factors 3 and 7 and the Janus kinase-signal transducer and activator of transcription cascade; these findings have revealed new insights into HEV-host interactions and provided the basis for understanding the pathogenesis and outcome of HEV infection.

AB - Secukinumab is a fully human monoclonal antibody that can selectively neutralize interleukin-17A, and its excellent efficacy has been demonstrated in clinical trials for psoriasis. The aim of our study is to assess long-term efficacy and safety of secukinumab for 52 weeks in real-world clinical practise in our facility. A total of 83 patients (71 with psoriasis vulgaris and 12 with psoriatic arthritis) were included, and 49 of them were bio-switched patients. Psoriasis Area and Severity Index (PASI) 75 and PASI-90 responses were 80% and 64% at week 12, 77% and 65% at week 24, and 76% and 58% at week 52, respectively. No significant differences were observed in efficacy between bio-naive and bio switched patients. Arthralgia showed improvement by week 12 in all patients with psoriatic arthritis with a reduction of serum C-reactive protein level. Treatment was discontinued in 22% (18/83), including eight patients with no improvement or exacerbation of cutaneous manifestations, one patient with new onset of arthritis and two patients with transient infection. Overall, secukinumab showed a sustained clinical response with an acceptable safety profile through week 52 in Japanese psoriatic patients. PMID- 29194724 TI - Reply.

AB - Diabetes mellitus (DM) is a metabolic disease defined by hyperglycemia, which is associated with periodontal disease and exerts an effect on bone metabolism. The aim of this study was to determine serum levels of sclerostin in postmenopausal women with diabetes and determine a possible association with periodontal disease. Sixty-one postmenopausal women (32 with diabetes and 29 without diabetes) were evaluated. Blood was collected for biochemical analysis and the determination of serum sclerostin. The participants were also submitted to a clinical examination for the evaluation of periodontal status. A total of 75.4% of the volunteers had periodontal disease and levels serum sclerostin were altered in 48.7% of the patients with diabetes. In the diabetic population, mean levels of LDL (p = 0.035) and urea (p = 0.032) were higher in the patients without periodontal disease and the plaque index was higher in those with periodontal disease (p = 0.039). The prevalence of periodontal disease and the levels serum sclerostin were high in the postmenopausal women analyzed, but the data do not allow the determination of whether periodontal disease is related to high levels of this peptide. PMID- 29194726 TI - The effects of acaricide treatment of sheep on red grouse Lagopus lagopus scotica tick burdens and productivity in a multi-host system. AB - Ixodes ricinus (Ixodida: Ixodidae) ticks are of economic and pathogenic importance across Europe. Within the uplands of the U.K., management to reduce ticks is undertaken to benefit red grouse Lagopus lagopus scotica (Galliformes: Phasianidae). Management strategies focus on the acaricide treatment of domestic sheep Ovis aries (Artiodactyla: Bovidae), but the effectiveness of this is less certain in the presence of wild hosts, particularly red deer Cervus elaphus (Artiodactyla: Cervidae) and mountain hare Lepus timidus (Lagomorpha: Leporidae). This study examines the effects of sheep management on grouse tick burdens and productivity using sites with a range of wild host densities. Sites at which applications of acaricide were more frequent had lower tick burdens; this relationship was similar on sites with a range of deer densities. However, no direct link was detected between acaricide treatment interval and grouse productivity. Sites with higher deer densities had higher grouse tick burdens and lower productivity [mean +/- standard error (SE) young : adult ratio: 1.2 +/- 0.2] compared with sites with lower deer densities (mean +/- SE young : adult ratio: 1.8 +/- 0.1). Sites with higher grouse brood sizes and higher proportions of hens with broods were also those with higher mountain hare abundance indices. This study highlights the importance of the frequent treatment of sheep with acaricide to reduce tick burdens on grouse, even in the presence of wild hosts. PMID- 29194727 TI - Diminished cerebral oxygen extraction and metabolic rate in sickle cell disease using T2 relaxation under spin tagging MRI. AB - PURPOSE: T2 MRI oximetry can noninvasively determine oxygen saturation (Y) but requires empirical MR calibration models to convert the measured blood transverse relaxation (T2b ) into Y. The accuracy of existing T2b models in the presence of blood disorders such as sickle cell disease (SCD) remains unknown. METHODS: A Carr Purcell Meiboom Gill T2 preparation sequence was used to make 83 whole blood measurements from 11 subjects with SCD to derive an ex vivo sickle hemoglobin (HbS) T2b model. Forearm venous blood gas, sagittal sinus T2 (T2 Relaxation Under Spin Tagging) and total brain blood flow (phase contrast MRI) were measured in 37 healthy controls and 33 SCD subjects (age 24.6 +/- 10.2 years). Cerebral oxygen saturation, extraction fraction, and metabolic rate estimates were calculated using three separate T2b models. Cerebral and forearm oxygen extraction fraction were compared. RESULTS: Ex vivo, SCD blood had greater saturation dependent relaxivity than control blood, with a weak dependence on HbS and no dependence on hematocrit. In vivo, the HbS T2b model predicted Yv values with lowest coefficient of variation (compared with existing T2b models) and the strongest correlation with peripheral venous oximetry (r2 = .29). The HbS T2b model predicted systematically higher Yv measurements in SCD patients (73 +/- 5 and 61 +/- 6; P < 0.0001) which was mirrored by peripheral venous measurements (75 +/- 20 and 45 +/- 20; P < 0.0001). CONCLUSION: Cerebral and peripheral oxygen extraction are decreased in SCD patients, suggesting either blood flow is increased beyond metabolic demands or the presence of physiological arterial venous shunting.

AB - Chordomas are rare bone tumors and treatment is commonly based on a combination of surgery and radiotherapy. There is no standard chemotherapy treatment for chordoma. The aim of this study was to determine the expression of cyclin dependent kinase 4 (CDK4) in chordoma and its therapeutic implications. We evaluated CDK4 expression both in chordoma cell lines and in chordoma tissues. Also, we investigated the functional roles of CDK4 in chordoma cell growth and proliferation. Furthermore, the therapeutic implications of targeting CDK4 in chordoma were evaluated. We found CDK4 highly expressed in chordoma cell lines and in a majority (97.7%) of chordoma tissues. Higher CDK4 expression correlated with metastasis and recurrence of chordoma. Treatment of chordoma cells using CDK4 inhibitor palbociclib could efficiently inhibit chordoma cells growth and proliferation. These data demonstrate that targeting CDK4 may be useful as a novel strategy in the treatment of chordoma. (c) 2017 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

AB - A range of novel pyridine-2,4,6-tricarbohydrazide thiourea compounds (4a-i) were synthesized in good to excellent yields (63-92%). The enzyme inhibitory potentials of these compounds were investigated against alpha- and beta glucosidases because these enzymes play a crucial role in treating type-2 diabetes mellitus (T2DM). As compared to the reference compound acarbose (IC50 38.22 +/- 0.12 MUM), compounds 4i (IC50 25.49 +/- 0.67 MUM), 4f (IC50 28.91 +/- 0.43 MUM), 4h (IC50 30.66 +/- 0.52 MUM), and 4e (IC50 35.01 +/- 0.45 MUM) delivered better inhibition against alpha-glucosidase and were quite inactive/completely inactive against beta-glucosidase. The structure-activity relationship of these compounds was developed and elaborated with the help of molecular docking studies. PMID- 29194731 TI - Human mesenchymal stem cells induced to differentiate as chondrocytes follow a biphasic pattern of extracellular matrix production. AB - Regenerative medicine and tissue engineering studies are actively developing novel means to repair adult articular cartilage defects using biological approaches. One such approach is the harnessing of adult human therapeutic cells such as those referred to as mesenchymal stem cells. Upon exposure to chondrogenic signals, these cells differentiate and initiate the production of a complex and voluminous cartilaginous matrix that is crucial to both the structure and function of cartilage. Furthermore, this complexity requires the time sensitive activation of a large number of genes to produce the components of this matrix. The current study analyzed the kinetics of matrix production in an aggregate culture model where adult human mesenchymal stem cells were induced to differentiate as chondrocytes. The results indicate the existence of a biphasic mode of differentiation and maturation during which matrix genes and molecules are differentially activated and secreted. These results have important implications for developing novel approaches for the creation of tissue engineered articular cartilage. (c) 2017 Orthopaedic Research Society.

AB - PURPOSE: A prerequisite for cardiac MR (CMR) imaging is adequate synchronization of image acquisition with the cardiac cycle. Electrocardiogram triggering may be hampered by electromagnetic interferences at high field strength. The purpose of this work is to evaluate the feasibility of Doppler ultrasound triggering for CMR image synchronization at 7T ultra-high-field MRI. METHODS: A custom-built Doppler ultrasound (DUS) trigger device was developed. Magnetic resonance compatibility was evaluated using E- and H-field probes and flip angle maps prior to the study. Cardiac MR was performed at 7T in 13 healthy subjects using DUS and pulse oximetry for triggering. For validation of the trigger signal, the electrocardiogram, pulse, and DUS signals were compared outside of the MR room. Breath-hold cine fast low-angle-shot sequences were acquired in short-axis and four-chamber view. Image quality was assessed by two senior radiologists and by measurement of endocardial blurring. RESULTS: The maximal change in E- and H field distributions with and without transducer was 5%. No interferences were observed between DUS and MRI in the B1 maps and during CMR imaging. Validation of the DUS trigger signal resulted in a high correlation to the electrocardiographic signal of r = 0.99. Analysis of image and trigger quality revealed no significant differences. CONCLUSION: Doppler ultrasound was applied as a new trigger method in CMR at 7T. The transmission line and transducer were locally approved as 7T MR conditional, and were successfully tested for image synchronization at 7T. In the future, this method needs to be evaluated in a larger patient population. Magn Reson Med 80:239-247, 2018. (c) 2017 International Society for Magnetic Resonance in Medicine. PMID- 29194733 TI - Activity of Group 2 Innate Lymphoid Cells is Associated with Chronic Inflammation and Dysregulated Metabolic Homoeostasis in Type 2 Diabetic Nephropathy. AB - The metabolic syndrome (MS) is an independent risk factor for type 2 diabetic nephropathy and accompanied by subclinical inflammation which involves immune deriving factors. Emerging studies indicate that group 2 innate lymphoid cells (ILC2s) can regulate adipose metabolism, but much less is known about the activity of ILC2s in metabolic imbalance in obesity and diabetes. This study explored the effect of ILC2s-related molecules on the occurrence of MS in type 2 diabetic nephropathy. Thirty patients with type 2 diabetic nephropathy were included in the study; the mRNA expression of ILC2s-associated molecules from peripheral blood mononuclear cell and the correlation of the ILC2s activity and the MS-related indicators were analysed. The results indicated that the waist circumference, fasting blood glucose, systolic blood pressure, diastolic blood pressure and triglyceride in patients with simple diabetes and diabetic nephropathy were increased, and the incidence of MS was 46.67% and 86.67%, respectively. The ILC2s-associated factors RORalpha, T1/ST2 and IL-5/IL-13 mRNA were increased in diabetic nephropathy. There was a positive correlation between the expression level of IL-13 or T1/ST2 mRNA and some MS indexes. In addition, the levels of plasma sTNFR, eotaxin-2 and I-309 were also increased in patients with type 2 diabetic nephropathy. It suggested that the patients with type 2 diabetic nephropathy were more likely to have multiple components of MS than those with simple type 2 diabetes mellitus, and enhanced ILC2s activity might be involved in the formation of MS in diabetic nephropathy via influencing blood pressure and lipid metabolism. PMID- 29194734 TI - In vivo characterization of brain ultrashort-T2 components. AB - PURPOSE: Recent nuclear magnetic resonance and MRI studies have measured a fast relaxing signal component with T2*<1 ms in white matter and myelin extracts. In ex vivo studies, evidence suggests that a large fraction of this component directly arises from bound protons in the myelin phospholipid membranes. Based on these results, this ultrashort-T2 component in nervous tissue is a new potential imaging biomarker of myelination, which plays a critical role in neuronal signal conduction across the brain and loss or degradation of myelin is a key feature of many neurological disorders. The goal of this work was to characterize the relaxation times and frequency shifts of ultrashort-T2 components in the human brain. METHODS: This required development of an ultrashort echo time relaxometry acquisition strategy and fitting procedure for robust measurements in the presence of ultrashort T2* relaxation times and large frequency shifts. RESULTS: We measured an ultrashort-T2 component in healthy volunteers with a median T2* between 0.5-0.7 ms at 3T and 0.2-0.3 ms at 7T as well as an approximately -3 ppm frequency shift from water. CONCLUSION: To our knowledge, this is the first time a chemical shift of the ultrashort-T2 brain component has been measured in vivo. This chemical shift, at around 1.7 ppm, is similar to the primary resonance of most lipids, indicating that much of the ultrashort-T2 component observed in vivo arises from bound protons in the myelin phospholipid membranes.

AB - New-onset psoriasis in patients receiving tumor necrosis factor inhibitors is well recognized in children and adults. We describe three children who underwent cardiac transplantation and developed an analogous form of paradoxic eczema occurring 2-48 months after starting systemic tacrolimus, a drug widely used topically to treat eczema. Anecdotal reports and our experience suggest that tacrolimus taper with alternative systemic antirejection immunosuppressant may lead to skin clearance. Pending additional insight, treatment should include optimizing skin barrier function, minimizing microbial and allergic triggers, and coordinating care to choose the best-tolerated systemic immunosuppressant regimen at the lowest effective dose. PMID- 29194737 TI - Differential expression of a fructose receptor gene in honey bee workers according to age and behavioral role. AB - Honey bee (Apis mellifera) workers contribute to the maintenance of colonies in various ways. The primary functions of workers are divided into two types depending on age: young workers (nurses) primarily engage in such behaviors as cleaning and food handling within the hive, whereas older workers (foragers) acquire floral nutrients beyond the colony. Concomitant with this age-dependent change in activity, physiological changes occur in the tissues and organs of workers. Nurses supply younger larvae with honey containing high levels of glucose and supply older larvae with honey containing high levels of fructose. Given that nurses must determine both the concentration and type of sugar used in honey, gustatory receptors (Gr) expressed in the chemosensory organs likely play a role in distinguishing between sugars. Glucose is recognized by Gr1 in honey bees (AmGr1); however, it remains unclear which Gr are responsible for fructose recognition. This study aimed to identify fructose receptors in honey bees and reported that AmGr3, when transiently expressed in Xenopus oocytes, responded only to fructose, and to no other sugars. We analyzed expression levels of AmGr3 to identify which tissues and organs of workers are involved in fructose recognition and determined that expression of AmGr3 was particularly high in the antennae and legs of nurses. Our results suggest that nurses use their antennae and legs to recognize fructose, and that AmGr3 functions as an accurate nutrient sensor used to maintain food quality in honey bee hives. PMID- 29194739 TI - Transverse signal decay under the weak field approximation: Theory and validation. AB - PURPOSE: To derive an expression for the transverse signal time course from systems in the motional narrowing regime, such as water diffusing in blood. This was validated in silico and experimentally with ex vivo blood samples. METHODS: A closed-form solution (CFS) for transverse signal decay under any train of refocusing pulses was derived using the weak field approximation. The CFS was validated via simulations of water molecules diffusing in the presence of spherical perturbers, with a range of sizes and under various pulse sequences. The CFS was compared with more conventional fits assuming monoexponential decay, including chemical exchange, using ex vivo blood Carr-Purcell-Meiboom-Gill data. RESULTS: From simulations, the CFS was shown to be valid in the motional narrowing regime and partially into the intermediate dephasing regime, with increased accuracy with increasing Carr-Purcell-Meiboom-Gill refocusing rate. In theoretical calculations of the CFS, fitting for the transverse relaxation rate (R2 ) gave excellent agreement with the weak field approximation expression for R2 for Carr-Purcell-Meiboom-Gill sequences, but diverged for free induction decay. These same results were confirmed in the ex vivo analysis. CONCLUSION: Transverse signal decay in the motional narrowing regime can be accurately described analytically. This theory has applications in areas such as tissue iron imaging, relaxometry of blood, and contrast agent imaging. Magn Reson Med 80:341 350, 2018.

AB - PURPOSE: To implement a reduced field of view (rFOV) technique for cardiac MR elastography (MRE) and to demonstrate the improvement in image quality of both magnitude images and post-processed MRE stiffness maps compared to the conventional full field of view (full-FOV) acquisition. METHODS: With Institutional Review Board approval, 17 healthy volunteers underwent both full FOV and rFOV cardiac MRE scans using 140-Hz vibrations. Two cardiac radiologists blindly compared the magnitude images and stiffness maps and graded the images based on several image quality attributes using a 5-point ordinal scale. Fisher's combined probability test was performed to assess the overall evaluation. The octahedral shear strain-based signal-to-noise ratio (OSS-SNR) and median stiffness over the left ventricular myocardium were also compared. RESULTS: One volunteer was excluded because of an inconsistent imaging resolution during the exam. In the remaining 16 volunteers (9 males, 7 females), the rFOV scans outperformed the full-FOV scans in terms of subjective image quality and ghosting artifacts in the magnitude images and stiffness maps, as well as the overall preference. The quantitative measurements showed that rFOV had significantly higher OSS-SNR (median: 1.4 [95% confidence interval (CI): 1.2-1.5] vs. 2.1 [95% CI: 1.8-2.4]), P < 0.05) compared to full-FOV. Although no significant change was found in the median myocardial stiffness between the 2 scans, we observed a decrease in the stiffness variation within the myocardium from 2.1 kPa (95% CI: [1.9, 2.3]) to 1.9 kPa (95% CI: [1.7, 2.0]) for full-FOV and rFOV, respectively (P < 0.05) in a subgroup of 7 subjects with ghosting present in the myocardium. CONCLUSION: This pilot volunteer study demonstrated that rFOV cardiac MRE has the capability to reduce ghosting and to improve image quality in both MRE magnitude images and stiffness maps.

PMID- 29194736 TI - MicroRNAs in orthopaedic research: Disease associations, potential therapeutic applications, and perspectives. AB - MicroRNAs (miRNAs) are small non-coding RNAs that function to control many cellular processes by their ability to suppress expression of specific target genes. Tens to hundreds of target genes may be affected by one miRNA, thereby resulting in modulation of multiple pathways in any given cell type. Therefore, altered expression of miRNAs (i.e., during tissue development or in scenarios of disease or cellular stress) can have a profound impact on processes regulating cell differentiation, metabolism, proliferation, or apoptosis, for example. Over the past 5-10 years, thousands of reports have been published on miRNAs in cartilage and bone biology or disease, thus highlighting the significance of these non-coding RNAs in regulating skeletal development and homeostasis. For the purpose of this review, we will focus on miRNAs or miRNA families that have demonstrated function in vivo within the context of cartilage, bone or other orthopaedic-related tissues (excluding muscle). Specifically, we will discuss studies that have utilized miRNA transgenic mouse models or in vivo approaches to target a miRNA with the aim of altering conditions such as osteoarthritis, osteoporosis and bone fractures in rodents. We will not discuss miRNAs in the context skeletal cancers since this topic is worthy of a review of its own. Overall, we aim to provide a comprehensive description of where the field currently stands with respect to the therapeutic potential of specific miRNAs to treat orthopaedic conditions and current technologies to target and modify miRNA function in vivo.

PMID- 29194740 TI - Stereotype Threat Effects on Learning From a Cognitively Demanding Mathematics Lesson. AB - Stereotype threat-a situational context in which individuals are concerned about confirming a negative stereotype-is often shown to impact test performance, with one hypothesized mechanism being that cognitive resources are temporarily co opted by intrusive thoughts and worries, leading individuals to underperform despite high content knowledge and ability (see Schmader & Beilock, ). We test here whether stereotype threat may also impact initial student learning and knowledge formation when experienced prior to instruction. Predominantly African American fifth-grade students provided either their race or the date before a videotaped, conceptually demanding mathematics lesson. Students who gave their race retained less learning over time, enjoyed the lesson less, reported a diminished desire to learn more, and were less likely to choose to engage in an optional math activity. The detrimental impact was greatest among students with high baseline cognitive resources. While stereotype threat has been well documented to harm test performance, the finding that effects extend to initial learning suggests that stereotype threat's contribution to achievement gaps may be greatly underestimated. PMID- 29194741 TI - "Double-hit" chronic lymphocytic leukemia: An aggressive subgroup with 17p deletion and 8q24 gain. AB - Chronic lymphocytic leukemia (CLL) with 17p deletion (17p-) is associated with a lack of response to standard treatment and thus the worst possible clinical outcome. Various chromosomal abnormalities (including unbalanced translocations, deletions, ring chromosomes and isochromosomes) result in the loss of 17p and one copy of the TP53 gene. The objective of the present study was to determine whether the type of chromosomal abnormality leading to 17p- and the additional aberrations influenced the prognosis in a series of 195 patients with 17p-CLL. Loss of 17p resulted primarily from an unbalanced translocation (70%) with several chromosome partners (the most frequent being chromosome 18q), followed by deletion 17p (23%), monosomy 17 (8%), isochromosome 17q [i(17q)] (5%) and a ring chromosome 17 (2%). In a univariate analysis, monosomy 17, a highly complex karyotype (>=5 abnormalities), and 8q24 gain were associated with poor treatment free survival, and i(17q) (P = .04), unbalanced translocations (P = .03) and 8q24 gain (P = .001) were significantly associated with poor overall survival. In a multivariate analysis, 8q24 gain remained a significant predictor of poor overall survival. We conclude that 17p deletion and 8q24 gain have a synergistic impact on outcome, and so patients with this "double-hit" CLL have a particularly poor prognosis. Systematic, targeting screening for 8q24 gain should therefore be considered in cases of 17p- CLL. PMID- 29194742 TI - Highly variable clinical feature and course of aggressive digital papillary adenocarcinoma. AB - Aggressive digital papillary adenocarcinoma (ADPA) is a rare cutaneous tumor with sweat gland differentiation. Due to the high risk of local recurrence and delayed metastasis, the wide local resection of the primary lesion and long-term follow up are recommended for ADPA. Here, we report two cases of ADPA. Case 1 had a blue gray nodule on the tip of the right middle finger. Case 2 had had a papule on the dorsal side of the left ring finger for 13 years. In both cases, papillary proliferations of the tumor cells showed multilobular adenomatous structures with back-to-back patterns characteristic of ADPA. We amputated the finger at the proximal interphalangeal joint and performed a wide resection of the primary tumor in Case 1 and 2, respectively. Sentinel lymph node biopsy in the axilla was performed, and no sentinel lymph node metastasis was found in either case. Among the previously reported ADPA cases, clinically, most lesions were skin-colored or tan-brown to gray. The blue-gray color in Case 1 is thought to be extraordinary for ADPA. In Case 2, the patient had had the small lesion for more than 13 years and the tumor size had been stable during that long period. The present two cases suggest that ADPA shows a prominent variety of both clinical features and disease courses, and that we cannot exclude the possibility of ADPA even in cases of blue gray nodules or small, stable, non-progressive papules. PMID- 29194743 TI - Optimizing venous outflow in reconstruction of Gustilo IIIB lower extremity traumas with soft tissue free flap coverage: Are two veins better than one? AB - PURPOSE: The dependent nature of the lower extremity predisposes to venous congestion, especially following significant trauma. The benefit of a second venous anastomosis, however, remains unclear in lower extremity trauma free flap reconstruction. This study investigated the effect of an additional venous anastomosis on flap outcomes in lower extremity trauma reconstruction. METHODS: Retrospective review between 1979 and 2016 identified 361 soft tissue flaps performed for Gustilo IIIB/C coverage meeting inclusion criteria. Muscle flaps were performed in 287 cases (79.9%) and fasciocutaneous flaps in 72 cases (20.1%). Single-vein anastomosis was performed in 76% of cases and dual-vein anastmoses in 24% of cases. Patient demographics, flap characteristics, and outcomes were examined. RESULTS: Fasciocutaneous flaps were more likely to have two veins performed (P < .001). Complications occurred in 143 flaps (39.8%): 45 take-backs (12.4%), 37 partial losses (10.3%), 31 complete losses (8.6%). Compared to single-vein flaps, two veins reduced major complications (P = .005), partial flap failures (P = .008), and any flap failure (P = .018). Multivariable regression analysis demonstrated two veins to be protective against complications (RR = 2.58, P = .009). Subset regression analysis by flap type demonstrated an even more significant reduction in complications among muscle flaps (RR = 3.92, P = .005). Additionally, a >1 mm vein size mismatch was predictive of total flap failure (RR = 3.02, P = .038). CONCLUSION: Lower extremity trauma free flaps with two venous anastomoses demonstrated a fourfold reduction in complication rates compared to single-vein flaps. Additionally, venous size mismatch >1 mm was an independent predictor of total flap failure, suggesting beneficial effects of both two-vein outflow and matched vessel diameter. PMID- 29194744 TI - Pharmacokinetics of the anticonvulsant levetiracetam in neonatal foals. AB - BACKGROUND: Seizures are a common manifestation of neurological disease in the neonatal foal and are an important cause of morbidity and mortality in this population. Current antiepileptic options are effective, but often have undesirable adverse effects, short duration of action and high cost. Levetiracetam has an ideal safety and pharmacokinetic profile in multiple species, including the adult horse, and may be a safe and cost-effective alternative anticonvulsant in neonatal foals. Due to differences in drug disposition and clearance dosages in neonates, dosing recommendations in other species or adult horses cannot be extrapolated to foals. OBJECTIVE: To establish the pharmacokinetic profile of single-dose i.v. and intragastric administration of levetiracetam in healthy neonatal foals. STUDY DESIGN: Randomised crossover experimental study. METHODS: Levetiracetam was administered as a single dose to six healthy foals (ages 1-10 days) at a dose of 32 mg/kg bwt i.v. or intragastrically. Plasma levetiracetam concentrations were measured using a validated HPLC protocol. RESULTS: After i.v. administration to healthy foals, levetiracetam had a mean (+/-s.d.) elimination half-life of 7.76 +/- 0.51 h, a mean systemic clearance of 61.67 +/- 10.96 (mL/h/kg) and a mean apparent volume of distribution at steady state of 0.670 +/- 0.124 (L/kg). Following intragastric administration, levetiracetam had a peak concentration of 38.34 +/- 7.42 mg/L and time to achieve peak concentration was 0.875 (0.5-1.5) h. Mean bioavailability for IG administration was excellent (103.04 +/- 14.51%). No significant differences in pharmacokinetic variables between routes and order of administration were observed. MAIN LIMITATIONS: Small sample size and single-dose administration. CONCLUSIONS: Levetiracetam has excellent intragastric bioavailability in foals and is predicted to maintain plasma concentrations at or above the proposed target concentration with twice daily i.v. or oral administration. Once-daily administration may be possible in some foals based on the therapeutic range recommended in other species. PMID- 29194745 TI - Biomechanical tolerance of whole lumbar spines in straightened posture subjected to axial acceleration. AB - Quantification of biomechanical tolerance is necessary for injury prediction and protection of vehicular occupants. This study experimentally quantified lumbar spine axial tolerance during accelerative environments simulating a variety of military and civilian scenarios. Intact human lumbar spines (T12-L5) were dynamically loaded using a custom-built drop tower. Twenty-three specimens were tested at sub-failure and failure levels consisting of peak axial forces between 2.6 and 7.9 kN and corresponding peak accelerations between 7 and 57 g. Military aircraft ejection and helicopter crashes fall within these high axial acceleration ranges. Testing was stopped following injury detection. Both peak force and acceleration were significant (p < 0.0001) injury predictors. Injury probability curves using parametric survival analysis were created for peak acceleration and peak force. Fifty-percent probability of injury (95%CI) for force and acceleration were 4.5 (3.9-5.2 kN), and 16 (13-19 g). A majority of injuries affected the L1 spinal level. Peak axial forces and accelerations were greater for specimens that sustained multiple injuries or injuries at L2-L5 spinal levels. In general, force-based tolerance was consistent with previous shorter-segment lumbar spine testing (3-5 vertebrae), although studies incorporating isolated vertebral bodies reported higher tolerance attributable to a different injury mechanism involving structural failure of the cortical shell. This study identified novel outcomes with regard to injury patterns, wherein more violent exposures produced more injuries in the caudal lumbar spine. This caudal migration was likely attributable to increased injury tolerance at lower lumbar spinal levels and a faster inertial mass recruitment process for high rate load application.

PMID- 29194746 TI - Pharmacokinetics of tiludronate in horses: A field population study. AB - BACKGROUND: Tiludronate is a bisphosphonate drug marketed to treat different bone conditions in horses. OBJECTIVES: The goal of this study was to measure the plasma concentrations of tiludronate in a population of race and sport horses under field conditions, and using pharmacokinetic population modelling, to estimate detection times for doping control. STUDY DESIGN: Prospective cohort. METHODS: This study was conducted under field conditions on 39 race or sport horses diagnosed with bone conditions based on a lameness examination and treated with tiludronate. Each horse received 1 mg/kg of tiludronate (Tildren(r) ) intravenously (i.v.). Blood samples (from 1 to 4 per horse with a total of 93 samples) were collected around 10, 20, 30, 40 and 50 days after tiludronate administration. Tiludronate was quantified by HPLC/ESI-MSn . Tiludronate concentrations were analysed using nonlinear mixed-effects modelling (population approach). Monte Carlo simulations were then used to compute a prediction interval to estimate the corresponding quantile of horses predicted to have concentrations below some potential screening limits. RESULTS: This study highlighted pharmacokinetic differences between healthy experimental horses and the population of horses being treated in the field as well as the effect of level of training on plasma tiludronate. Different detection times were computed corresponding to different possible screening limits. MAIN LIMITATIONS: The number of horses in each group was limited, and the specific disease being treated with tiludronate is unknown. CONCLUSIONS: This population pharmacokinetic study on tiludronate will enable racing and other sports authorities to provide a detection time reflecting field conditions for the medication control of tiludronate. More generally, our study design and the data modelling serve as an example of how to generate detection times directly from the target horse population rather than from experimental horses. PMID- 29194747 TI - Standardization of hemipelvis alignment for in vitro biomechanical testing. AB - Although in vitro biomechanical tests are regularly performed, the definition of a suitable reference frame for hemipelvic specimens is still a challenge. The aims of the present study were to: (i) define a reference frame for the human hemipelvis suitable for in vitro applications, based on robust anatomical landmarks; (ii) identify the alignment of a hemipelvis based on the alignment of a whole pelvis (including right/left and male/female differences); (iii) identify the relative alignment of the proposed in vitro reference frame with respect to a reference frame commonly used in gait analysis; (iv) create an in vitro alignment procedure easy, robust and inexpensive; (v) quantify the intra-operator repeatability and inter-operator reproducibility of the procedure. A procedure to univocally identify the anatomical landmarks was created, exploiting the in vitro accessibility of the specimen's surface. Through the analysis on 53 CT scans (106 hemipelvises), the alignment of the hemipelvis based on the alignment of a whole pelvis was analyzed: differences between male/female and right/left hemipelvises were not statistically significant To overcome the uncertainty in the identification of the acetabular rim, a standard acetabular plane was defined. An alignment procedure was developed to implement such anatomical reference frame. The intra-operator repeatability and the inter-operator reproducibility were quantified with four operators, on male and female hemipelvises. The intra operator repeatability was better than 1.5 degrees . The inter-operator reproducibility was better than 2.0 degrees . Alignment in the transverse plane was the most repeatable. The presented procedure to align hemipelvic specimens is sufficiently robust, standardized, and accessible. (c) 2017 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

AB - Primary osteoarthritis (OA) is the most common type of a joint disease. It has a polygenic risk inheritance pattern and affects older people. The etiology of this disease is not fully understood. The aim of this study was to investigate the associations between polymorphisms in pro-inflammatory interleukin-17 (IL17A and IL17F) and anti-inflammatory Toll-like Receptor 10 (TLR10) genes with the risk for development of advanced stage hip and knee primary OA in the Croatian population. A total of 500 OA patients and 597 controls were genotyped for IL17A SNP (rs2275913), IL17F SNPs (rs763780 and rs1889570), and TLR10 (rs11096957) genes. The allelic and genotypic frequencies of IL17F SNP (rs763780) showed statistically significant differences in comparisons of controls with hip-but not knee-OA patients. The major allele (T) of rs763780 was associated with the lower risk for developing hip OA (p = 7.9 * 10-4 , OR = 0.45, 95%CI = 0.27-0.74), whereas the minor allele (C) was associated with susceptibility to hip OA (p = 7.9 * 10-4 , OR = 2.24, 95%CI = 1.35-3.72). The genotype T/T was associated with the protection to hip OA (p = 3.9 * 10-4 , OR = 0.41, 95%CI = 0.24-0.70), and, lastly, the genotype T/C was associated with the higher risk to acquiring hip OA (p = 2.6 * 10-4 , OR = 2.50, 95%CI = 1.47-4.25). TLR10 SNP rs11096957 was found significantly associated with predisposition to hip OA (p = 0.04, OR = 1.41, 95%CI = 1.02-1.94) but not knee OA.

AB - Previously, we reported on bone histomorphometry, biochemical markers, and bone mineral density distribution after 6 and 24 months of treatment with teriparatide (TPTD) or zoledronic acid (ZOL) in the SHOTZ study. The study included a 12-month primary study period, with treatment (TPTD 20 MUg/d by subcutaneous injection or ZOL 5 mg/yr by intravenous infusion) randomized and double-blind until the month 6 biopsy (TPTD, n = 28; ZOL, n = 30 evaluable), then open-label, with an optional 12-month extension receiving the original treatment. A second biopsy (TPTD, n = 10; ZOL, n = 9) was collected from the contralateral side at month 24. Here we present data on remodeling-based bone formation (RBF), modeling-based bone formation (MBF), and overflow modeling-based bone formation (oMBF, modeling overflow adjacent to RBF sites) in the cancellous, endocortical, and periosteal envelopes. RBF was significantly greater after TPTD versus ZOL in all envelopes at 6 and 24 months, except the periosteal envelope at 24 months. MBF was significantly greater with TPTD in all envelopes at 6 months but not at 24 months. oMBF was significantly greater at 6 months in the cancellous and endocortical envelopes with TPTD, with no significant differences at 24 months. At 6 months, total bone formation surface was also significantly greater in each envelope with TPTD treatment (all p < 0.001). For within-group comparisons from 6 to 24 months, no statistically significant changes were observed in RBF, MBF, or oMBF in any envelope for either the TPTD or ZOL treatment groups. Overall, TPTD treatment was associated with greater bone formation than ZOL. Taken together the data support the view that ZOL is a traditional antiremodeling agent, wheareas TPTD is a proremodeling anabolic agent that increases bone formation, especially that associated with bone remodeling, including related overflow modeling, with substantial modeling-based bone formation early in the course of treatment.

PMID- 29194752 TI - The Regulatory Role of the Oral Commensal Streptococcus mitis on Human Monocytes. AB - Streptococcus mitis colonizes all niches of the human oral cavity from early infancy and throughout life. Monocytes patrol blood vessels, lymphoid and non lymphoid tissues and migrate into infected tissue where they participate in the inflammatory cascade and immune regulation. Here, we studied the effect of S. mitis on monocytes. Transcriptome analysis of monocytes exposed to S. mitis (SmMo) revealed increased transcription of chemotactic factors (CCL2, CCL3, CCL20, CXCL1, CXCL2) and cytokines (IL1A, IL1B, IL6, IL23, IL36G, TNF), indicating that S. mitis may trigger recruitment of leucocytes and initiate inflammation. Increased transcription in SmMo of IL1B, IL6 and IL23 indicated that S. mitis may participate in the induction of Th17 responses and agreed with our earlier findings of S. mitis-mediated memory Th17 reactivity. Furthermore, S. mitis inhibited tetanus toxoid-specific CD4 T cell proliferation. This can be due to the increased secretion of IL-10 and expression of PD-L1 that was observed in SmMo. PGE2 can modulate IL-10 and PD-L1 expression, concomitant with that of CCR7, IL-12 and IL-23 that also were changed. This, along with increased SmMo transcription of PTGS2 (COX2) and PTGER4 (EP4), pointed to a role of PGE2. Measurement of PGE2 secretion by SmMo showed indeed a marked increase, and chemical inhibition of PGE2 production lowered the PD-L1 expression on SmMo. In conclusion, our findings show that S. mitis may trigger immune modulation by recruiting immune cells to the site of infection, while at the same time dampening the severity of the response through expression of IL-10, PGE2 and PD L1.

AB - Respiratory syncytial virus (RSV) is a common cause of respiratory infections in infants. Effective vaccines are currently being sought, but no vaccine is thus far available. In our previous study, recombinant AIK-C measles vaccine expressing the RSV fusion protein (MVAIK/RSV/F) was developed and protective immunity against RSV demonstrated in cotton rats. In the present study, the immunogenicity and protective effects were investigated in three cynomolgus monkeys immunized with MVAIK/RSV/F. Neutralizing test antibodies against RSV were detected and no infectious virus was recovered from the lungs of monkeys immunized with MVAIK/RSV/F after challenge. MVAIK/RSV/F has the potential to inhibit RSV infection. PMID- 29194754 TI - The mechanism of nucleotide-binding domain dimerization in the intact maltose transporter as studied by all-atom molecular dynamics simulations. AB - The Escherichia coli maltose transporter MalFGK2 -E belongs to the protein superfamily of ATP-binding cassette (ABC) transporters. This protein is composed of heterodimeric transmembrane domains (TMDs) MalF and MalG, and the homodimeric nucleotide-binding domains (NBDs) MalK2 . In addition to the TMDs and NBDs, the periplasmic maltose binding protein MalE captures maltose and shuttle it to the transporter. In this study, we performed all-atom molecular dynamics (MD) simulations on the maltose transporter and found that both the binding of MalE to the periplasmic side of the TMDs and binding of ATP to the MalK2 are necessary to facilitate the conformational change from the inward-facing state to the occluded state, in which MalK2 is completely dimerized. MalE binding suppressed the fluctuation of the TMDs and MalF periplasmic region (MalF-P2), and thus prevented the incorrect arrangement of the MalF C-terminal (TM8) helix. Without MalE binding, the MalF TM8 helix showed a tendency to intrude into the substrate translocation pathway, hindering the closure of the MalK2 . This observation is consistent with previous mutagenesis experimental results on MalF and provides a new point of view regarding the understanding of the substrate translocation mechanism of the maltose transporter.

PMID- 29194756 TI - A higher level of ketonaemia does not predict oral rehydration failure in vomiting paediatric patients and routine measurement is unnecessary. AB - AIM: This study determined if blood levels of beta-hydroxybutyrate were associated with the rate of failure in oral rehydration in paediatric patients with vomiting. METHODS: This was a prospective observational study that was carried out from December 1, 2015 to November 30, 2016 in the Rio Hortega University Hospital, Valladolid, Spain. The study cohort were patients up to 14 years old who attended the emergency department with three or more vomiting episodes in the last four hours and glycaemia higher than 45 mg/dL. Blood was measured for beta-hydroxybutyrate levels prior to the administration of oral rehydration solution for 90 minutes. Two or more vomiting episodes during this period were considered failed oral rehydration. RESULTS: We analysed 248 patients, with a median age of four years and 7.5 months and 233 (94%) of the parents took part. The median number of vomiting episodes in the previous four hours was five and oral rehydration was successful in 183 (78.5%) patients. The multivariate analysis showed that the initial beta-hydroxybutyrate blood level was not associated with the failure of oral rehydration. CONCLUSION: Blood levels of beta-hydroxybutyrate had no predictive value for oral rehydration failure in young patients with vomiting and this routine measurement is unnecessary.

PMID- 29194758 TI - Utility of transthoracic needle biopsy after lung transplantation. AB - The purpose of this study was to assess the diagnostic yield and complications of CT-guided transthoracic needle biopsy (TTNB) after lung transplantation. A database search identified all TTNB performed in lung transplant patients over a 14-year period. Forty-two biopsies in transplant patients (transplant group) were identified and matched to the next biopsy performed in native lungs by the same operator (nontransplant group) as a control. Primary outcomes recorded were diagnosis, diagnostic yield, pneumothorax requiring intervention, and symptomatic pulmonary hemorrhage. Biopsy outcomes were classified as diagnostic, not specifically diagnostic, and nondiagnostic. Patients in the transplant group were younger (P < .002). Emphysema along the biopsy trajectory was more commonly seen in the nontransplant group (P < .0006). Needle gauge, size of lesion, pleural punctures, lesion depth, and number of passes were not significantly different. Diagnostic yield was 71% in the transplant group and 91% in the nontransplant group. There were 20 of 42 (48%) malignant nodules in the transplant group compared to 31 of 44 (70%) nodules in the nontransplant group (P = .05). There were no complications in the transplant group. The nontransplant group had two pneumothoraces requiring intervention. TTNB after lung transplant is safe with a moderate diagnostic yield. Nonmalignant lesions are more common after lung transplantation. PMID- 29194759 TI - Association between urine retinol-binding protein levels and nonalcoholic fatty liver disease: A cross-sectional study in Chinese population. AB - OBJECTIVE: The prevalence of nonalcoholic fatty liver disease (NAFLD) has been rapidly increased, becoming a public health problem worldwide. Our objective was to investigate the association between urine retinol-binding protein (RBP) and NAFLD in a Chinese population and develop a multivariate logistic regression model for NAFLD prediction. METHODS: A total of 317 NAFLD patients and 391 healthy controls were enrolled in this cross-sectional study based on inclusion and exclusion criteria, from whom fasting urine and blood were collected for further study. Urine RBP level and other parameters were measured and compared between NAFLD subjects and controls. RESULTS: Urine RBP levels (expressed by RBP/creatinine ratio) in NAFLD patients were significantly higher than controls (median 133.1 mg/g vs 110.7 mg/g; P < .001). Urine RBP/creatinine ratio was verified as an independent factor for NAFLD prediction after adjustment in multivariate logistic regression. The area under curve (AUC) of receiver operating characteristic (ROC) was 0.889 with the 95% confidence interval from 0.867 to 0.912.With a cutoff point of 0.215, the sensitivity and specificity of urine RBP/creatinine ratio in NAFLD prediction were 81.1% and 84.5%, respectively. CONCLUSION: Our results demonstrated that urine RBP/creatinine ratio was an independent risk factor for NAFLD while the predictive model for NAFLD diagnosis is noninvasive with high sensitivity and specificity.

AB - Spotted wing drosophila, Drosophila suzukii, is an invasive pest that primarily attacks fresh, soft-skinned fruit. Although others have reported successful integration of marked piggyBac elements into the D. suzukii genome, with a very respectable transgenesis rate of ~16%, here we take this work a step further by creating D. suzukii jumpstarter strains. These were generated through integration of a fluorescent-marked Minos element carrying a heat shock protein 70-driven piggyBac transposase gene. We demonstrate that there is a dramatic increase in transformation rates when germline transformation is performed in a transposase expressing background. For example, we achieved transformation rates as high as 80% when microinjecting piggyBac-based plasmids into embryos derived from one of these D. suzukii jumpstarter strains. We also investigate the effect of insert size on transformation efficiency by testing the ability of the most efficient jumpstarter strain to catalyze integration of differently-sized piggyBac elements. Finally, we demonstrate the ability of a jumpstarter strain to remobilize an already-integrated piggyBac element to a new location, demonstrating that our jumpstarter strains could be used in conjunction with a piggyBac-based donor strain for genome-wide mutagenesis of D. suzukii. PMID- 29194762 TI - Cholinesterase levels predict exercise capacity in cardiac recipients early after transplantation. AB - PURPOSE: Although cardiac rehabilitation is recommended for patients early after heart transplantation (HTx), adequate exercise effect cannot always be obtained, partly because in patients with chronic heart failure, exercise capacity is reduced due to malnutrition while waiting for HTx. This study aimed to investigate the relationships between exercise capacity and clinical variables, including nutritional indicators, early after HTx. PATIENTS AND METHODS: Forty three HTx recipients were studied. The mean age at HTx was 38 +/- 14 years, and 86% were male. We assessed the relationships between peak oxygen uptake (VO2 ) and clinical variables, including plasma B-type natriuretic peptide (BNP), isometric knee extensor muscle strength (KEMS), and nutritional indicators within 1 week of their respective discharges. RESULTS: Peak VO2 correlated positively with isometric KEMS (r = .63, P < .0001) and negatively with BNP level (r = -.37, P = .015). Of the nutritional indicators, only cholinesterase levels had a significant relationship with peak VO2 (r = .34, P = .028), whereas the Geriatric Nutritional Risk Index and the Controlling Nutritional Status scores did not. In multiple linear regression analysis, cholinesterase levels and isometric KEMS were independent predictors of peak VO2 . CONCLUSION: Cholinesterase levels predicted exercise capacity early after HTx. PMID- 29194763 TI - Posttraumatic Stress, Somatization, and Quality of Life Among Ivorian Refugees. AB - The present study examined the relationship between peritraumatic reactions, posttraumatic stress disorder (PTSD) symptoms, somatization, and quality of life (QoL) in a sample of refugees, two years after the 2011 Ivory Coast sociopolitical crisis. Participants were 101 Ivorian adult refugees (mean age = 31.61 years, SD = 7.84; 45.5% women) who completed several questionnaires relating to peritraumatic reactions, PTSD symptoms, somatization, and QoL. Most participants (86.1%) scored above the cutoff for probable PTSD. Peritraumatic dissociation and peritraumatic distress were significantly associated with PTSD symptoms, (r = .64, p < .001) and (r = .60, p < .001), respectively, and somatization, (r = .21, p = .038) and (r = .35, p < .001), respectively, as well as with QoL, (r = -.20, p = .045) and (r = -.21, p = .037), respectively. Similarly, QoL was significantly negatively correlated with PTSD symptoms (r = .33, p < .001) and somatization (r = -.39, p < .001). In multivariate analyses, somatization was the strongest predictor of QoL (beta = -.31, p = .003). Finally, somatization statistically mediated the association between peritraumatic distress and QoL. These findings suggest that PTSD may be frequent among Ivorian refugees, and that somatization may be an important feature of the traumatic experiences. Targeting somatization in conjunction with trauma-centered therapy may improve outcomes in sub-Saharan Africans with PTSD. PMID- 29194760 TI - Hepatic Fibrosis in Dogs. AB - Hepatic fibrosis is commonly diagnosed in dogs, often as a sequela to chronic hepatitis (CH). The development of fibrosis is a crucial event in the progression of hepatic disease that is of prognostic value. The pathophysiology of hepatic fibrosis in human patients and rodent models has been studied extensively. Although less is known about this process in dogs, evidence suggests that fibrogenic mechanisms are similar between species and that activation of hepatic stellate cells is a key step. Diagnosis and staging of hepatic fibrosis in dogs requires histopathological examination of a liver biopsy specimen. However, performing a liver biopsy is invasive and assessment of fibrotic stage is complicated by the absence of a universally accepted staging scheme in veterinary medicine. Serum biomarkers that can discriminate among different fibrosis stages are used in human patients, but such markers must be more completely evaluated in dogs before clinical use. When successful treatment of its underlying cause is feasible, reversal of hepatic fibrosis has been shown to be possible in rodent models and human patients. Reversal of fibrosis has not been well documented in dogs, but successful treatment of CH is possible. In human medicine, better understanding of the pathomechanisms of hepatic fibrosis is leading to the development of novel treatment strategies. In time, these may be applied to dogs. This article comparatively reviews the pathogenesis of hepatic fibrosis, its diagnosis, and its treatment in dogs. PMID- 29194764 TI - A comparative study found that a seven-year school-based exercise programme increased physical activity levels in both sexes. AB - AIM: This study assessed whether a Swedish school-based exercise intervention programme could increase total physical activity. METHODS: We followed up 228 children who started school in 1998-2000 seven years later, when they had reached a mean age of 14.8. The 152 children (59% boys) at the intervention school did 200 minutes of physical education per week during that period, and the 76 children (50% boys) in the three control schools did the standard 60 minutes. Questionnaires assessed the durations of total and leisure-time physical activity and screen-time activity at baseline and after five and seven years. RESULTS: Physical activity and screen-time activity were similar between the two groups before the study started. The intervention group then achieved higher durations of total physical activity than the controls (p < 0.001) and these levels remained in the sex-specific evaluations. There were no differences between the groups in the durations of leisure-time activity (p 0.08-0.77) or screen-time activity (p 0.31-0.91). CONCLUSION: A school-based exercise intervention programme increased the total duration of physical activity in both sexes without any compensatory increase in screen-time activity. The findings contradict the activity-stat theory, which stated that the duration of physical activity in children is constant. PMID- 29194765 TI - c-Kit Mutation and Localization Status as Response Predictors in Mast Cell Tumors in Dogs Treated with Prednisone and Toceranib or Vinblastine. AB - BACKGROUND: KIT inhibitors, such as toceranib (TOC), and vinblastine (VBL) have not been prospectively compared in the treatment of macroscopic mast cell tumors (MCTs). Also, it is unknown whether VBL or TOC is superior for treating MCT without c-kit mutations. HYPOTHESIS/OBJECTIVES: To determine the value of KIT genotyping and localization in treatment decisions for dogs with macroscopic MCT. We hypothesized that c-kit mutated MCT would have a better response to TOC than VBL. ANIMALS: Eighty-eight client-owned dogs with macroscopic MCT. METHODS: Prospective, randomized trial. Dogs were randomized to TOC (2.75 mg/kg EOD) or VBL (2.5 mg/m2 weekly * 4 then EOW) by KIT localization and c-kit mutation status using an adaptive randomization scheme. RESULTS: Sixty dogs were allocated to TOC and 28 to VBL. Of the dogs receiving TOC, 20% had c-kit mutations, compared to 30% receiving VBL (P = 0.74). Overall response rates were 46% (TOC) and 30% (VBL) (odds ratio = 1.56 [0.62-3.92]; P = 0.28). Median progression-free survival (PFS) for dogs receiving VBL was 78 days (7-1,521) and for TOC 95.5 (14-990); hazard ratio (HR) = 1.34 [0.72-2.50]; P = 0.36. Median overall survival (OS) was 241.5 days (10-1,521) for the VBL group and 159 (20-990) for the TOC group; HR = 0.80 ([0.45-1.41]; P = 0.44). CONCLUSIONS AND CLINICAL IMPORTANCE: Neither PFS nor OS was significantly different between treatment groups. As the proportion of dogs with c-kit mutations was not different between treatment groups in this population of dogs, c-kit mutation status did not predict treatment response. PMID- 29194767 TI - Evolution of lung and kidney allograft function in patients receiving kidney after lung transplantation. AB - Calcineurin inhibitor (CNI) toxicity leads to end-stage renal disease in almost half of long-term survivors after lung transplantation, some of them receiving kidney transplants. Little is known about the outcomes of kidney and lung allograft function following kidney after lung transplantation (KALTPL) in the modern era. We retrospectively analyzed a group of 13 consecutive patients who received a KALTPL with respect to their renal and pulmonary function and immunological evolution over 2 years. We documented a stable evolution of forced expiratory volume in 1 second (FEV1) after KALTPL in most patients as well as an excellent kidney graft during the 2-year follow-up period. In our small cohort, living donations showed a significantly higher estimated glomerular filtration rate compared to deceased donation (75.7 compared to 41.6 mL/min). Patients who received a preemptive KALTPL were more likely to improve their lung function after KALTPL. Four patients developed de novo donor-specific antibodies (DSA) against the kidney graft. There were no DSA against shared antigens from the lung allograft. De novo DSA did not lead to graft loss in any patient. All 13 patients survived the first 24 months after KALTPL. PMID- 29194766 TI - Absence Seizures as a Feature of Juvenile Myoclonic Epilepsy in Rhodesian Ridgeback Dogs. AB - Myoclonic epilepsy in Rhodesian Ridgeback (RR) dogs is characterized by myoclonic seizures occurring mainly during relaxation periods, a juvenile age of onset and generalized tonic-clonic seizures in one-third of patients. An 8-month-old female intact RR was presented for myoclonic seizures and staring episodes that both started at 10 weeks of age. Testing for the DIRAS1 variant indicated a homozygous mutant genotype. Unsedated wireless video-electroencephalography (EEG) identified frequent, bilaterally synchronous, generalized 4 Hz spike-and-wave complexes (SWC) during the staring episodes in addition to the characteristic myoclonic seizures with generalized 4-5 Hz SWC or 4-5 Hz slowing. Photic stimulation did not evoke a photoparoxysmal response. Repeat video-EEG 2 months after initiation of levetiracetam treatment disclosed a >95% decrease in frequency of myoclonic seizures, and absence seizures were no longer evident. Absence seizures represent another seizure type in juvenile myoclonic epilepsy (JME) in RR dogs, which reinforces its parallels to JME in humans.

PMID- 29194769 TI - Intravascular ultrasound of the proximal left anterior descending artery is sufficient to detect early cardiac allograft vasculopathy. AB - OBJECTIVE: Cardiac allograft vasculopathy (CAV) can be detected early with intravascular ultrasound (IVUS), but there is limited information on the most efficient imaging protocol. METHODS: Coronary angiography and IVUS of the three coronary arteries were performed. Volumetric IVUS analysis was performed, and a Stanford grade determined for each vessel. RESULTS: Eighteen patients were included 18 (range 12-24) months after transplantation. Angiographic CAV severity ranged from none (CAV0) to mild (CAV1), whereas IVUS CAV severity ranged from none (Stanford grade I) to severe (grade IV). Maximal intimal thickness measured with IVUS was significantly greater in the LAD (0.84 +/- 0.48 mm) than in the LCX (0.46 +/- 0.32 mm) or the RCA (0.53 +/- 0.41 mm, P = .005). Diagnostic accuracy of IVUS in the left anterior descending artery was 100% (18 of 18 Stanford grades matched the patient's highest overall Stanford grade), 66% in the right coronary artery (12 of 18), and 56% in the left circumflex artery (11 of 18). The minimal required length of left anterior descending artery pullbacks to attain 100% accuracy was 36 mm (range 3-36 mm) distal from the guide catheter ostium. CONCLUSIONS: These data suggest that focal IVUS imaging of the proximal LAD followed by volumetric analysis may suffice when screening for transplant vasculopathy. PMID- 29194771 TI - Outcomes of indwelling metallic stents for malignant extrinsic ureteral obstruction. AB - OBJECTIVES: To report the treatment outcomes of patients with extrinsic ureteral obstruction treated with metallic stents and to identify the factors predicting stent failure. METHODS: A total of 52 patients with extrinsic ureteral obstruction as a result of malignancy (66 ureters) were treated with metallic stents (Resonance(r) ) and included in the study. The median observation period was 118 days. RESULTS: The median survival time of these patients was 210 days, and the stent patency rate was 86.0% at 6 months and 60.0% at 1 year. Eight (15.4%) patients underwent nephrostomy as a result of stent failure. The occlusion rate of bilateral ureteral obstructed cases was significantly higher than that of unilateral cases. There was no correlation between the preoperative serum creatinine level, causes of ureteral occlusions (compression by tumor, lymph node metastasis, peritoneal dissemination), obstructed site (upper, middle, lower ureter) and stent failure. CONCLUSIONS: Metallic stents are excellent in maintaining patency compared with the conventional stents. Therefore, they can be used as first-line treatment of malignant ureteral obstructions. PMID- 29194770 TI - Differences in Epidural Pathology between Cervical and Thoracolumbar Intervertebral Disk Extrusions in Dogs. AB - BACKGROUND: Although the basic pathophysiology is the same in both cervical and thoracolumbar intervertebral disk (IVD) extrusions, there are considerable clinical differences that have only been partially explained. HYPOTHESIS/OBJECTIVES: The epidural inflammatory response differs between cervical and thoracolumbar IVD extrusions. ANIMALS: Fifty-five dogs with cervical and 80 dogs with thoracolumbar IVD extrusions. METHODS: Clinical data and histopathologic variables were investigated. Associations between severity of epidural inflammation and clinical and pathologic variables, impact of chondrodystrophic phenotype, and localization (cervical versus thoracolumbar) were evaluated statistically. RESULTS: Dogs with cervical IVD extrusion were significantly older (P < 0.001), had less severe and longer duration of neurologic signs (both P < 0.001), were more painful (P = 0.038), and had a better outcome (P = 0.005) than dogs with a thoracolumbar IVD extrusion. On histopathology, cervical epidural material had less severe calcification (P = 0.002) and inflammation (P < 0.001). No significant differences regarding chondrodystrophic phenotype were found. CONCLUSION AND CLINICAL IMPORTANCE: There was significantly less intensive inflammatory response in the cervical epidural space. This observation correlated positively with less nucleus pulposus calcification in cervical extrusions indicating biochemical, metabolic, and biomechanical differences between the 2 locations, which remain to be characterized in future studies. PMID- 29194772 TI - Comparison of Multiplate, Platelet Function Analyzer-200, and Plateletworks in Healthy Dogs Treated with Aspirin and Clopidogrel. AB - BACKGROUND: Platelet function testing may be warranted to assess response to aspirin and clopidogrel. HYPOTHESIS/OBJECTIVES: To evaluate the effects of aspirin, clopidogrel, or combination therapy using 3 platelet function tests: Multiplate Analyzer (MP), Platelet Function Analyzer-200 (PFA), and Plateletworks (PW). ANIMALS: Six healthy laboratory Beagles. METHODS: Randomized double-blind placebo-controlled study (crossover design). Dogs were given aspirin 1 mg/kg, clopidogrel 2 mg/kg, or combination therapy for 1 week each, with a washout period of 2 weeks. Platelet function was assessed on days 0 and 7 of each phase using MP (adenosine diphosphate [ADP], arachidonic acid [AA], collagen [COL] agonists), PFA (P2Y, COL-ADP [CADP], COL-Epinephrine [CEPI] cartridges), and PW (ADP, AA, COL agonists). Platelet counts were obtained with impedance and optical counters. RESULTS: For MP, mean aggregation was decreased for COL and AA with combination therapy and for ADP with all treatments. For PFA, mean CT was increased for the CEPI cartridge with aspirin; and for the P2Y and CADP cartridges with clopidogrel or combination therapy. More dogs receiving clopidogrel showed an increase in PFA CT using the P2Y than the CADP cartridge. For PW, mean aggregation was decreased for AA with all treatments; for ADP with clopidogrel or combination therapy; and for COL with clopidogrel. The PW results with the 2 hematology counters showed almost perfect agreement. CONCLUSION AND CLINICAL IMPORTANCE: All platelet function tests detected treatment effects in some dogs and may have utility for monitoring therapy. PMID- 29194773 TI - Plasma IL-8 signature correlates with pain and depressive symptomatology in patients with burning mouth syndrome: Results from a pilot study. AB - BACKGROUND: Burning mouth syndrome (BMS) is a neuropathic orofacial pain condition of unknown aetiology that encompasses intra-oral burning pain without abnormal clinical findings. Psychological, neural and inflammatory processes are associated with BMS pathogenesis. Currently, studies characterising plasma cytokine/chemokine profiles with pain and depression in patients with BMS are lacking. Considering that inflammation is associated with the pathophysiology of BMS, and that inflammation is closely associated with pain and depression, we aimed to correlate depressive symptomatology and oral cavity pain with plasma cytokine/chemokine signatures in a cohort of patients with BMS. METHODS: In this study, plasma protein levels of Th1 cytokines (IFN-gamma, IL-2, IL-12p70, TNF alpha), Th2 cytokines (IL-4, IL-10, IL-6, IL-13) and the chemokine IL-8 were assessed in patients with BMS (n = 10) and healthy volunteers (n = 10), using pro inflammatory-10-plex assays. Clinical histories, alongside self-rated oral cavity pain intensities and depressive symptomatology were assessed using a visual analogue scale and the 16-item Quick Inventory of Depressive Symptomatology questionnaires, respectively. RESULTS: We present evidence that BMS is associated with increased depressive symptomatology and enhanced oral cavity pain. Plasma isolated from BMS patients display enhanced expression of the pro-inflammatory chemokine IL-8, when compared to plasma from healthy individuals. Plasma IL-8 signature correlates with pain and depressive symptomatology in the study cohort. CONCLUSIONS: Overall, these findings indicate that plasma IL-8 profiles are dysregulated in BMS and that modulation of IL-8 production in the disorder may be a tool in the management of BMS symptomatology. PMID- 29194774 TI - Current clinical algorithms for predicting common bile duct stones have only moderate accuracy. AB - BACKGROUND AND AIM: A risk-stratified approach for selecting patients likely to harbor common bile duct (CBD) stones to proceed directly to endoscopic or surgical stone clearance, rather than undergo less invasive testing, has been proposed. We assessed the performance of three clinical algorithms used to predict CBD stones. METHODS: All patients undergoing first-time endoscopic retrograde cholangiopancreatography (ERCP) in 2011-2012 as a result of suspected CBD stones were enrolled prospectively in a clinical database. Data such as imaging test findings and liver function tests (LFTs) were collected 48 h prior to and on the day of ERCP. Patients were stratified into different risk groups for harboring CBD stones according to three clinical algorithms using imaging and laboratory data. Findings on ERCP were used as gold standard. Performance characteristics of each algorithm were separately calculated for each time point of LFT assessment. RESULTS: Overall, 186 patients were analyzed, 75% of whom presented CBD stones on ERCP. Proportion of patients categorized as high-risk for harboring CBD stones varied among the three algorithms (67% vs 73% vs 56%). Also, the algorithms showed only moderate, albeit comparable, accuracy for predicting the presence of CBD stones (0.65, 95% confidence interval [CI] 0.62-0.68 vs 0.68, 95% CI 0.63-0.67 vs 0.59, 95% CI 0.57-0.61). Similar results were obtained when performance characteristics were recalculated using LFT from 48 h prior to ERCP (data not shown). CONCLUSION: Three diagnostic algorithms commonly used for predicting CBD stones have comparable but only moderate accuracy. Further research is warranted to improve risk stratification of patients with suspected CBD stones.

AB - BACKGROUND AND AIM: Most studies of diarrhea-predominant irritable bowel syndrome (IBS-D) focused on microbiota dysbiosis in a single segment of the intestine such as the colon. However, the intestine as a whole is involved in IBS-D and knowledge about the role of microbiota shared by the duodenum and rectum in IBS-D is limited. Here, we investigated the characteristics of mucosal microbiota shared by the duodenum and rectum in IBS-D patients. METHODS: We collected duodenal and rectal mucosal samples from 33 adult IBS-D patients and 15 healthy control (HC) subjects. The 454 pyrosequencing method and multiple bioinformatics analyses were used to examine bacterial 16S rRNA. Clinical data including symptoms and Bristol Stool Form were analyzed. RESULTS: Mucosal microbiota in duodenal samples differed from rectal samples in HC, while less difference was shown in IBS-D. More numbers in terms of shared operational taxonomic units and genera found in IBS-D compared with HC. The frequency of genera in the duodenum and rectum of HC differed from that of IBS-D. We identified 24 genera shared in the duodenum and rectum, which both changed dramatically in IBS-D. Among these 24 genera, half had similar trends in frequency differences, and the other half had opposite trends. The frequency of Faecalibacterium and Hyphomicrobium were associated with clinical data of IBS-D patients. CONCLUSIONS: Shared mucosal associated microbiota in the duodenum and rectum appear to contribute to the etiology and pathophysiology of whole intestine of IBS-D and to be potential therapeutic targets. PMID- 29194776 TI - Endosymbiosis and its significance in dermatology. AB - Proposed at the beginning of the twentieth century to explain the origin of eukaryotic organelles from prokaryotes, endosymbiosis is now medically defined by various interaction patterns between microorganisms and their residing hosts, best exemplified by the bacterial endosymbiont Wolbachia identified in arthropods and filarial nematodes, which can influence normal development, reproduction, survival and transmission of the hosts. Based on the transmission modes, vertical or horizontal, and the function of the endosymbionts, the host-symbiont dependence can be divided into primary or secondary. In dermatology, the role of endosymbionts in skin ectoparasitosis has aroused great interests in the past years. Riesia pediculicola is a primary bacterial endosymbiont in body lice Pediculus humanus, and supplement their hosts with vitamin B, especially pantothenic acid. In cimicosis, the Gram-negative Wolbachia can synthesize biotin and riboflavin, which are crucial for the growth and reproduction of the bedbug Cimex lectularius. In human demodicosis and rosacea, further study is required to prove the pathogenic role of the Gram-negative bacteria Bacillus oleronius or the Gram-positive bacteria Bacillus cereus demonstrated in the Demodex mites. The high infection rate of adult female ticks Ixodes ricinus with the Gram-negative bacteria Midichloria mitochondrii present in the mitochondria in diverse ovarian cells, with the high seroprevalence rate in tick-exposed subjects, raises the possibility that this non-pathogenic endosymbiont may play a role in immune response and successful transmission of the tick-borne pathogen. The anaerobic protozoan Trichomonas vaginalis and bacteria Mycoplasma hominis are two obligate parasites in the urogenital epithelium, with partially overlapping symptoms. Intracellular localization of Mycoplasma hominis can avoid host immune response and penetration of antibiotics, while Trichomonas vaginalis infected with Mycoplasma hominis seems to have a higher cytopathic activity and amoeboid transformation rate. Further study on the biology and pathogenesis of different endosymbionts in dermatological parasitosis will help for the development of new treatment modalities.

AB - Rechargeable magnesium/sulfur battery is of significant interest because its energy density (1700 Wh kg-1 and 3200 Wh L-1 ) is among the highest of all battery chemistries (lower than Li/O2 and Mg/O2 but comparable to Li/S), and Mg metal allows reversible operation (100% Coulombic efficiency) with no dendrite formation. This great promise is already justified in some early reports. However, lack of mechanistic study of sulfur reaction in the Mg cation environment has severely hindered our understanding and prevents effective measures for performance improvement. In this work, the very first systematic fundamental study on Mg/S system is conducted by combining experimental methods with computational approach. The thermodynamics and reaction pathway of sulfur cathode in MgTFSI2 -DME electrolyte, as well as the associated kinetics are thoroughly investigated. The results here reveal that sulfur undergoes a consecutive staging pathway in which the formation and chain-shortening of polysulfide occur at early stage accompanied by the dissolution of long-chain polysulfide, and solid-state transition from short-chain polysulfide to magnesium sulfide occurs at late stage. The former process is much faster than the latter due to the synergetic effect of the mediating effect of dissolved polysulfide and the fast diffusion of Mg ion in the amorphous intermediate.

In this article, the author presents a historical review of the disease. In particular, the review is focused on the main steps, including the definition of Bence Jones proteinuria, the characterization of tumoral plasma cells and serum globulins, and the fundamental contribution of Jan Waldenstrom. Finally, treatment of multiple myeloma, as well as the development of new agents, is discussed. PMID- 29194779 TI - The pathological kinematic patterns of the tarsal complex in stage II adult acquired flatfoot deformity. AB - The in vivo kinematic characteristics of the tarsal joints during gait stance phase were still unclear in adult-acquired foot deformity (AAFD). This study included seven healthy subjects (fourteen feet) and twelve stage II AAFD patients (fourteen feet). The 3D models of tarsal bones were reconstructed based on CT scan. Each subject took standard gait on the single fluoroscopy system. Continuous lateral fluoroscopic images were collected. The key postures during the stance phase were selected. The 2D-3D registration technique was applied to explore the spatial motions of the tarsal joints in 6 degrees of freedom (DOF). During the whole stance phase, the AAFD talo-navicular joint (TNJ) exhibited ROM of 13+/-6 degrees in the sagittal plane while the normal subjects showed ROM of 7+/-3 degrees (P=0.004). In AAFD, the subtalar joint (STJ) demonstrated 19+/-8 degrees and 7+/-3 degrees of motion in coronal and horizontal plane respectively while the normal subjects showed 14+/-4 degrees (p=0.031) and 11+/-3 degrees (p=0.014) of motion respectively. Additionally STJ of AAFD patients showed significantly less dorsiflexion during the weight acceptance and showed significantly less external rotation both during the weight acceptance and single limb support of stance phase. In conclusion, for stage II AAFD patients, the talonavicular joint and the subtalar joint showed hypermobility in dorsi/planterflexion and inversion/eversion respectively during the gait stance phase while the internal/external rotation of the subtalar joint was reduced. The current study improves our understanding of the pathological kinematics of the tarsal complex in AAFD patients. Notice should be taken about these tarsal joints mobility in AAFD during clinical practice. This article is protected by copyright. All rights reserved. PMID- 29194780 TI - Black Phosphorus Nanosheets as a Neuroprotective Nanomedicine for Neurodegenerative Disorder Therapy. AB - Transition-metal dyshomeostasis is recognized as a critical pathogenic factor at the onset and progression of neurodegenerative disorder (ND). Excess transition metal ions such as Cu2+ can catalyze the generation of cytotoxic reactive oxygen species and thereafter induce neuronal cell apoptosis. Exploring new chelating agents, which are not only capable of capturing excess redox-active metal, but can also cross the blood-brain barrier (BBB), are highly desired for ND therapy. Herein, it is demonstrated that 2D black phosphorus (BP) nanosheets can capture Cu2+ efficiently and selectively to protect neuronal cells from Cu2+ -induced neurotoxicity. Moreover, both in vitro and in vivo studies show that the BBB permeability of BP nanosheets is significantly improved under near-infrared laser irradiation due to their strong photothermal effect, which overcomes the drawback of conventional chelating agents. Furthermore, the excellent biocompatibility and stability guarantee the biosafety of BP in future clinical applications. Therefore, these features make BP nanosheets have the great potential to work as an efficient neuroprotective nanodrug for ND therapy. PMID- 29194781 TI - Toward Customized Extracellular Niche Engineering: Progress in Cell-Entrapment Technologies. AB - The primary aim in tissue engineering is to repair, replace, and regenerate dysfunctional tissues to restore homeostasis. Cell delivery for repair and regeneration is gaining impetus with our understanding of constructing tissue like environments. However, the perpetual challenge is to identify innovative materials or re-engineer natural materials to model cell-specific tissue-like 3D modules, which can seamlessly integrate and restore functions of the target organ. To devise an optimal functional microenvironment, it is essential to define how simple is complex enough to trigger tissue regeneration or restore cellular function. Here, the purposeful transition of cell immobilization from a cytoprotection point of view to that of a cell-instructive approach is examined, with advances in the understanding of cell-material interactions in a 3D context, and with a view to further application of the knowledge for the development of newer and complex hierarchical tissue assemblies for better examination of cell behavior and offering customized cell-based therapies for tissue engineering.

PMID- 29194783 TI - Assessing dutasteride-associated sexual dysfunction using the U.S. Food and Drug Administration Adverse Event Reporting System. AB - BACKGROUND: Incidences of sexual dysfunction due to the use of 5 alpha-reductase inhibitors have been suggested. Despite low sexual dysfunction reported in clinical trials, an analysis of the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) database revealed a significant disproportionality in the reporting of sexual dysfunction with the use of finasteride. Therefore, it is likely that a similar relationship with dutasteride may exist. OBJECTIVE: To determine whether dutasteride use leads to a higher risk of sexual dysfunction compared to a baseline risk for all other drugs using the FAERS database. METHODS: A case by non-case disproportionality approach was used whereby a reporting odds ratio (ROR) with 95% confidence interval (CI) was calculated. Cases of dutasteride-associated sexual dysfunction were compared to a reference risk of sexual dysfunction for all other drugs in the database. RESULTS: A significant disproportionality in reporting of sexual dysfunction with the use of dutasteride was observed. The disproportionality was present for all age ranges except for 31-45 years where there were few overall reports of adverse events. LIMITATIONS: Adverse events can be underreported, and selection bias is inherent in the FAERS. CONCLUSION: Dutasteride use is associated with an increase in reports of sexual dysfunction.

PMID- 29194785 TI - Molecular basis for immunohistochemical and inflammatory changes during progression of gingivitis to periodontitis. AB - Two common diseases - gingivitis and periodontitis - affect the periodontium. Symptoms of disease entities are used for distinguishing various forms of gingivitis and periodontitis. Gingivitis follows a linear and progressive course when a healthy individual stops oral care, as shown by the experimental gingivitis model. It is not known if and when gingivitis transforms into periodontitis. A very limited number of studies present direct evidence regarding the histological changes over time and how they correlate to the clinical transition from gingivitis to periodontitis. This review focuses on the pathological changes that occur during the progression of gingivitis into periodontitis through discussing the molecular, cellular and immunohistochemical aspects of the inflammatory process. Molecular pathways regulating periodontal inflammation also determine the outcomes of disease and healing. Treatment of inflammatory diseases, particularly periodontitis in which extensive tissue damage could result from the inflammatory process, needs to target full restoration of the lost tissues. This can only be accomplished by a thorough understanding of the activation and resolution of periodontal disease and of the molecular events that occur during these phases. PMID- 29194786 TI - Microneedling for the treatment of hair loss? AB - Microneedling is a minimally invasive dermatological procedure in which fine needles are rolled over the skin to puncture the stratum corneum. This therapy is used to induce collagen formation, neovascularization and growth factor production of treated areas. It has been used in a wide range of dermatologic conditions, including androgenetic alopecia (AGA) and alopecia areata, among others. While there are a limited number of studies examining this therapy in the use of hair loss, microneedling has been successfully paired with other hair growth promoting therapies, such as minoxidil, platelet-rich plasma and topical steroids, and shown to stimulate hair follicle growth. It is thought that microneedling facilitates penetration of such first-line medications, and this is one mechanism by which it promotes hair growth. To date, the area most studied and with the most success has been microneedling treatment of AGA. While the current evidence does not allow one to conclude superiority of microneedling over existing standard therapies for hair loss, microneedling shows some promise in improving hair growth, especially in combination with existing techniques. This review summarizes the current literature regarding microneedling in the treatment of alopecia and calls for further studies to define a standard treatment protocol. PMID- 29194787 TI - Photonic Crystal Phosphors Integrated on a Blue LED Chip for Efficient White Light Generation. AB - Following the proof-of-concept experiment in the unit structure level, photonic crystal (PhC) phosphors-structurally engineered phosphor materials based on the nanophotonics principles-are integrated with a blue light-emitting diode (LED) chip to demonstrate a compact and efficient white light source. Red- or green emitting CdSe-based colloidal quantum dots (CQDs) are coated on a Si3 N4 thin film grating to fabricate PhC phosphors. The underlying PhC structure is designed such that the photonic band-edge modes at the zone center (k?? = 0) are tuned to the energy of the blue excitation photons. By progressively stacking the PhC phosphor plates on a blue LED chip, the blue, green, and red emission intensities can be tightly controlled to obtain white light with the desired properties. The chromaticity coordinates, (0.332, 0.341), and correlated color temperature, 5500 K, are obtained from a stack of 3 red and 11 green PhC phosphor plates; in contrast, a stack of 5 red and 16 green reference phosphor plates are required to generate a similar white light. Overall, the PhC phosphors produce 8% higher total emission intensity out of 33% less amount of CQDs than the reference phosphors.

PMID- 29194789 TI - Dermoscopic features and patterns of poromas: a multicentre observational case control study conducted by the International Dermoscopy Society. AB - BACKGROUND: Poromas are benign cutaneous sweat gland tumours that are challenging to identify. The dermoscopic features of poromas are not well characterized. OBJECTIVE: To determine the clinical-dermoscopic features of poromas. METHODS: Cross-sectional, observational study of 113 poromas and 106 matched control lesions from 16 contributors and eight countries. Blinded reviewers evaluated the clinical and dermoscopic features present in each clinical and dermoscopic image. RESULTS: Poromas were most commonly non-pigmented (85.8%), papules (35.4%) and located on non-acral sites (65.5%). In multivariate analysis, dermoscopic features associated with poroma included white interlacing areas around vessels (OR: 7.9, 95% CI: 1.9-32.5, P = 0.004), yellow structureless areas (OR: 2.5, 95% CI: 1.1-6.0, P = 0.04), milky-red globules (OR: 3.9, 95% CI: 1.4-11.1, P = 0.01) and poorly visualized vessels (OR: 33.3, 95% CI: 1.9-586.5, P = 0.02). The presence of branched vessels with rounded endings was positively associated with poromas but did not reach statistical significance (OR: 2.4, 95% CI: 0.8-6.5, P = 0.10). The presence of any of these five features was associated with a sensitivity and specificity of 62.8% and 82.0%, respectively. CONCLUSION: We identified dermoscopic features that are specific to the diagnosis of poroma. Overall, however, the prevalence of these features was low. Significant clinical and dermoscopic variability is a hallmark of these uncommon tumours, which are most prevalent on non-acral sites. PMID- 29194790 TI - Associations between air pollution, climate factors and outpatient visits for eczema in West China Hospital, Chengdu, south-western China: a time series analysis. AB - BACKGROUND: Eczema is one of the most common inflammatory dermatoses that can be provoked as a result of external and internal factors. With dense population and rapid economic development of China, air pollution is still a serious problem and the prevalence of eczema has been elevating. OBJECTIVE: To determine the association and lagged effects between environmental factors and the outpatient visits for eczema. METHODS: Data of daily outpatient visits for eczema at the clinics of dermatology in West China Hospital within the last 5 years were collected. Data of environmental factors of Chengdu during the same period, including temperature, relative humidity, barometric pressure, wind speed and air pollutants concentrations like sulphur dioxide (SO2 ), nitrogen dioxide (NO2 ) and particular matter (PM10 ), were gathered. The distributed lag nonlinear model was used to statistically examine the relationship between eczema and environmental factors and their lagged effects. RESULTS: Correlation analysis showed that eczema outpatient visits were positively correlated with the air pollutants and were negatively correlated with relative humidity. The barometric pressure and wind speed influenced the outpatient visits in association with air pollutants. CONCLUSION: This study provides evidence that environmental factors like relative humidity and multiple air pollutants influence the incidence and prevalence of eczema and have lagged effects.

PMID- 29194793 TI - Dry Etching with Nanoparticles: Formation of High Aspect-Ratio Pores and Channels Using Magnetic Gold Nanoclusters. AB - Methods for generating nanopores in substrates typically involve one or more wet etching steps. Here a fundamentally different approach to produce nanopores in sheet substrates under dry, ambient conditions, using nanosecond-pulsed laser irradiation and magnetic gold nanoclusters (MGNCs) as the etching agents is described. Thermoplastic films (50-75 um thickness) are coated with MGNCs then exposed to laser pulses with a coaxial magnetic field gradient, resulting in high aspect ratio channels with tapered cross sections as characterized by confocal fluorescence tomography. The dry-etching process is applicable to a wide variety of substrates ranging from fluoropolymers to borosilicate glass, with etch rates in excess of 1 um s-1 . Finite-element modeling suggests that the absorption of laser pulses by MGNCs can produce temperature spikes of nearly 1000 degrees C, which is sufficient for generating photoacoustic responses that can drive particles into the medium, guided by magnetomotive force. PMID- 29194794 TI - The periodontal pocket. AB - Periodontal disease is synonymous with the presence of periodontal pockets, and very often the clinical success of periodontal therapy is based on periodontal pocket depth reduction. Therefore, in the fields of periodontology and implant dentistry, significant research effort has been placed on the etiopathogenesis, diagnosis and treatment of periodontal/peri-implant disease and as a consequence on pocket pathology. In this volume of Periodontology 2000, the in-depth reviews include topics ranging from preclinical models, anatomy and structure of tissues, and molecular and bacterial components, to treatments of pockets around teeth and implants. These reviews aim to provide the readers with current and future perspectives on the different areas of research into the periodontal pocket. PMID- 29194795 TI - Description of the periodontal pocket in preclinical models: limitations and considerations. AB - Establishment of periodontal health and regeneration of the lost periodontal tissues are always the ultimate goal of periodontal treatment. The development of new therapeutic approaches raises the necessity for appropriate experimental models that present periodontal structures and healing capability comparable to humans. Preclinical research and extrapolation of the data to human conditions remains a stage of great importance before the clinical application of the new biomaterials and techniques. Periodontal pockets/defects in preclinical models can be induced experimentally through acute or chronic or a combination of both (induced) modalities. The features of the created defects and those of humans vary greatly mostly due to the nature of the periodontal disease. This is an important point to take into account, since it is well recognized that the potential of periodontal therapy may be dependent on both the biological background and the defect morphology. This review provides insight into the commonly used preclinical models for the reproduction of the periodontal pocket and discusses the advantages and disadvantages of each model in terms of similarity to human conditions, standardization and reproducibility. PMID- 29194796 TI - The periodontal pocket: pathogenesis, histopathology and consequences. AB - The conversion of junctional epithelium to pocket epithelium is regarded as a hallmark in the development of periodontitis. Knowledge of factors contributing to the initiation and progression of pocket formation is important and may result in the development of better preventive measures and improve healing outcomes after therapeutic interventions. The periodontal pocket is a pathologically deepened gingival sulcus. In healthy periodontal conditions, the defense mechanisms are generally sufficient to control the constant microbiological challenge through a normally functioning junctional epithelium and the concentrated powerful mass of inflammatory and immune cells and macromolecules transmigrating through this epithelium. In contrast, destruction of the structural integrity of the junctional epithelium, which includes disruption of cell-to-cell contacts and detachment from the tooth surface, consequently leading to pocket formation, disequilibrates this delicate defense system. Deepening of the pocket apically, and also horizontal expansion of the biofilm on the tooth root, puts this system to a grueling test. There is no more this powerful concentration of defense cells and macromolecules that are discharged at the sulcus bottom and that face a relatively small biofilm surface in the gingival sulcus. In a pocket situation, the defense cells and the macromolecules are directly discharged into the periodontal pocket and the majority of epithelial cells directly face the biofilm. The thinning of the epithelium and its ulceration increase the chance for invasion of microorganisms and their products into the soft connective tissue and this aggravates the situation. Depending on the severity and duration of disease, a vicious circle may develop in the pocket environment, which is difficult or impossible to break without therapeutic intervention. PMID- 29194797 TI - Dental calculus: the calcified biofilm and its role in disease development. AB - Dental calculus represents the first fossilized record of bacterial communities as a testimony of evolutionary biology. The development of dental calculus is a dynamic process that starts with a nonmineralized biofilm which eventually calcifies. Nonmineralized dental biofilm entraps particles from the oral cavity, including large amounts of oral bacteria, human proteins, viruses and food remnants, and preserves their DNA. The process of mineralization involves metabolic activities of the bacterial colonies and strengthens the attachment of nonmineralized biofilms to the tooth surface. From a clinical point of view, dental calculus always harbors a living, nonmineralized biofilm, jeopardizing the integrity of the dento-gingival or implanto-mucosal unit. This narrative review presents a brief historical overview of dental calculus formation and its clinical relevance in modern periodontal practice. PMID- 29194798 TI - Efficacy and tolerance of GELOXD/P-GEMOXD in newly diagnosed nasal-type extranodal NK/T-cell lymphoma: A multicenter retrospective study. AB - OBJECTIVES: Nasal-type extranodal natural killer NK/T-cell lymphoma (ENKTCL) is a distinct type of non-Hodgkin lymphoma with poor prognosis. This research aimed to evaluate the efficacy and safety of the GELOXD or P-GEMOXD regimens in patients with ENKTCL. METHODS: Newly diagnosed ENKTCL patients treated with either the GELOXD or the P-GEMOXD regimen were identified from three cancer centers between January 2010 and December 2016. Kaplan-Meier and Cox regression analyses were used to calculate overall survival (OS) and progression-free survival (PFS) and to investigate prognostic factors. RESULTS: One hundred and eighty-four cases were identified from three cancer centers. After 1-5 treatment cycles of GELOXD or P-GEMOXD chemotherapy, 155 (84%) patients showed a complete response (CR). The 3-year OS (73.0% vs 38.2%, P = .001) and PFS (72.8% vs 32.4%, P = .000) rates were significantly higher in early-stage patients compared with advanced-stage patients. A multivariate analysis revealed that patient CR status was a significant independent factor in disease prognosis. Grade 3/4 leukopenia occurred in 43 (23.4%) patients. Major non-hematological toxicities included nausea (n = 117, 63.6%) and vomiting (n = 66, 35.9%). CONCLUSIONS: The GELOXD and P-GEMOXD chemotherapy regimens are well tolerated and provide favorable survival outcomes in patients with ENKTCL. PMID- 29194799 TI - Hyperstage Graphite: Electrochemical Synthesis and Spontaneous Reactive Exfoliation. AB - Covalent modification of the pi-electron basal planes of graphene enables the formation of new materials with enhanced functionality. An electrochemical method is reported for the formation of what is referred to as a Hyperstage-1 graphite intercalation compound (GIC), which has a very large interlayer spacing d001 > 15.3 A and contains disordered interstitial molecules/ions. This material is highly activated and undergoes spontaneous exfoliation when reacted with diazonium ions to produce soluble graphenes with high functionalization densities of one pendant aromatic ring for every 12 graphene carbons. Critical to achieving high functionalization density is the Hyperstage-1 GIC state, a weakening of the van der Waals coupling between adjacent graphene layers, and the ability of reactants to diffuse into the disordered intercalate phase between the layers. Graphene functionalization with 3,5-dinitrophenyl groups provides for exceptional dispersibility (0.24 mg mL-1 ) in N,N-dimethylformamide and for conjugation with amines. PMID- 29194800 TI - Expression of IFNAR1 and IFNAR2 in cattle placenta during early pregnancy. AB - Interferon-tau (IFNT), a type I interferon, is an antiluteolytic factor secreted by trophoderm during pregnancy. IFNT transmitted signals or stimulated the expression of some factors to build maternal recognition and keep pregnancy by binding its receptors, IFNT receptor 1(IFNAR1) and IFNT receptor 2 (IFNAR2). Up to now, the expression model and roles of IFNAR1 and IFNAR2 in placenta have not been investigated in cattle. In this study, the localization and expression of IFNAR1 and IFNAR2 in the cattle placenta at days 18-50 of pregnancy were detected by histological examination, immunofluorescence staining and real-time qPCR. The results showed that IFNAR1 mainly distributed in chorioallantoic membrane, endometrial epithelium, cotyledon and caruncle during the early pregnancy of cattle with change in time- and position-dependent. IFNAR1 and IFNAR2 mRNA expression were mainly detected in chorioallantoic membrane and cotyledon, and markedly increased along with pregnancy process. Moreover, the mRNA expression level of IFNAR1 in chorioallantoic membrane and cotyledon was higher than that of IFNAR2. IFNAR mRNA was also expressed in caruncle tissues, which experienced a tendency of decrease from days 21 to 36, followed by increase after days 36. These results provide morphological basis and quantitative data for investigating the roles of IFNAR1 and IFNAR2 on development of cattle placenta and pregnancy maintenance. PMID- 29194801 TI - Measurement of HE4 and CA125 and establishment of reference intervals for the ROMA index in the sera of pregnant women. AB - INTRODUCTION: Cancer antigen 125 (CA125) and human epididymis protein 4 (HE4) are biomarkers for ovarian cancer. Their specificity and sensitivity are often limited during pregnancy as a result of great fluctuations. The risk of ovarian malignancy algorithm (ROMA) score, which combines CA125, HE4, and menopausal status, may improve diagnostic performance. There are no reports regarding the ROMA index in pregnant women. Therefore, the aim of our study was to establish appropriate reference intervals (RIs) for the ROMA index in pregnant Chinese women and compare them with those of CA125 and HE4 during pregnancy. METHODS: Serum concentrations of CA125 and HE4 were simultaneously measured in healthy pregnant women via electrochemiluminescence immunoassay (ECLIA). The ROMA index was calculated using premenopausal algorithms. RESULTS: The RIs for the ROMA index calculated by premenopausal algorithms were substantially closer to the normal range in the first 2 trimesters. For pregnant women, the great misclassifications identified in CA125 may be reversed by the use of ROMA index. CONCLUSIONS: We established the RIs for HE4 and CA125, as well as the ROMA index, in pregnant women at different gestational periods. The ROMA index is suggested to be a more promising tumor marker for pregnant women diagnosed with malignance. PMID- 29194802 TI - Acne across Europe: an online survey on perceptions and management of acne. AB - BACKGROUND: Acne is common among young people. OBJECTIVE: To describe the burden, management and sources of advice of acne in a representative sample of young people in Europe. METHODS: This cross-sectional survey was conducted in a representative sample of individuals aged 15-24 years from Belgium, Czech and Slovak Republics, France, Italy, Poland and Spain (n = 3099). RESULTS: Most individuals considered their acne (all severity stages) to be no/minor problem, although 29.7% considered it a major problem/burden. Over-the-counter (OTC) topical treatments were used more frequently than prescribed treatments. Acne was diagnosed by physicians in 47.6% of cases; other health professionals (nurses, pharmacists) or patients accounted for the remainder of diagnoses. Physicians were the source of acne information in just over one-quarter of cases (27.0%). The vast majority of advice was from friends/family and the Internet. CONCLUSION: Almost one-third of young people consider acne to be a major problem/burden. Fewer than half of acne diagnoses are made by a physician, and acne is often self managed using OTC treatments. PMID- 29194803 TI - A Li-Air Battery with Ultralong Cycle Life in Ambient Air. AB - The Li-air battery represents a promising power candidate for future electronics due to its extremely high energy density. However, the use of Li-air batteries is largely limited by their poor cyclability in ambient air. Herein, Li-air batteries with ultralong 610 cycles in ambient air are created by combination of low-density polyethylene film that prevents water erosion and gel electrolyte that contains a redox mediator of LiI. The low-density polyethylene film can restrain the side reactions of the discharge product of Li2 O2 to Li2 CO3 in ambient air, while the LiI can facilitate the electrochemical decomposition of Li2 O2 during charging, which improves the reversibility of the Li-air battery. All the components of the Li-air battery are flexible, which is particularly desirable for portable and wearable electronic devices. PMID- 29194804 TI - The use of ultrasonography in the reproductive evaluation of boars. AB - The objective was to study the use of ultrasound as a complementary test in the breeding soundness evaluation in male pigs and study the pattern of echogenicity of the testicular parenchyma in boars of different racial groups. Twenty-six adult boars from four different racial groups were used, 10 from the Piau breed (group 1), four from the commercial and finishing group (group 2), six Pietrain breed (group 3) and six from the Duroc breed (group 4). All animals were evaluated for breeding soundness evaluation and the ultrasound examination of the testicles. The groups of animals that were evaluated showed no difference in the main semen parameters that were evaluated, except for the sperm volume, concentration of the ejaculated sperm and the supravital staining; the lowest figures were for the animals from the Piau breed (group 1). In relation to the testicular biometrics, Duroc animals (group 4) had a greater scrotal width compared to the other groups. But when we assessed the intensity of pixels of the testicles, there was a difference between groups. The groups 2 (finishing animals), 3 (Pietrain) and 4 had no difference between themselves. Group 3 had greater pixel intensity in relation to group 1. Of the 26 animals studied, five showed an abnormality during ultrasound evaluation, like hydrocele, hyperechoic mass in the testicular parenchyma, cyst in the head of the epididymis and the presence of fluid in the head and tail of the epididymis. The various animal groups studied did not differ in the principal reproductive parameters evaluated, showing that despite the great variability of reproductive traits between breeds and within the same breed, the breeding soundness evaluation, the more complete it is, is essential for the selection of breeders and the ultrasonography of the reproductive system becomes an important addition in this examination.

However, the RNA World hypothesis places special demands on prebiotic chemistry, which must now deliver not only four ribonucleosides, but also must deliver the "functional" portion of these RNA cofactors. While some (e.g., methionine) present no particular challenges, nicotinamide ribose is special. Essential to its role in biological oxidations and reductions, its glycosidic bond that holds a positively charged heterocycle is especially unstable with respect to cleavage. Nevertheless, we are able to report here a prebiotic synthesis of phosphorylated nicotinamide ribose under conditions that also conveniently lead to the adenosine phosphate components of this and other RNA cofactors. PMID- 29194808 TI - The changing landscape of surgery for Parkinson's Disease. AB - Neurosurgical interventions have been used to treat PD for over a century. We examined the changing landscape of surgery for PD to appraise the value of various procedures in the context of advances in our understanding and technology. We assessed the number of articles published on neurosurgical procedures for PD over time as an albeit imprecise surrogate for their usage level. We identified over 8,000 publications associated with PD surgery. Over half the publications were on DBS. The field of DBS for PD showed a rapid rise in articles, but is now in a steady state. Thalamotomy and, to a lesser extent, pallidotomy follow a biphasic publication distribution with peaks approximately 30 years apart. Articles on gene therapy and transplantation experienced initial rapid rises and significant recent declines. Procedures using novel technologies, including gamma knife and focused ultrasound, are emerging, but are yet to have significant impact as measured by publication numbers. Pallidotomy and thalamotomy are prominent examples of procedures that were popular, declined, and re-emerged and redeclined. Transplantation and gene therapy have never broken into clinical practice. DBS overtook all procedures as the dominant surgical intervention and drove widespread use of surgery for PD. Notwithstanding, the number of DBS articles appears to have plateaued. As advances continue, emerging treatments may compete with DBS in the future. (c) 2017 International Parkinson and Movement Disorder Society.

AB - Persistent Mullerian duct syndrome (PMDS) is a sex-limited disorder in which males develop portions of the female reproductive tract. Important consequences of PMDS are cryptorchidism and its sequelae of infertility and increased risk of testicular cancer. Anti-Mullerian hormone (AMH) and its receptor (AMHR2) induce the regression of the Mullerian ducts in male embryos. In Miniature Schnauzer dogs, the genetic basis has been identified as an autosomal recessive nonsense mutation in AMHR2, but the allele frequency of the mutation is unknown. Thus, the primary objective of this study was to estimate the prevalence of the AMHR2 mutation in North American Miniature Schnauzers, in order to ascertain the value of genetic testing in this breed. An additional objective was to determine whether mutations in AMH or AMHR2 were responsible for PMDS in a Belgian Malinois; this would aid development of a genetic test for the Belgian Malinois breed. Genomic DNA from 216 Miniature Schnauzers (including one known PMDS case) was genotyped for the AMHR2 mutation, and DNA from a single PMDS-affected Belgian Malinois was sequenced for all coding exons of AMH and AMHR2. The Miniature Schnauzer cohort had an AMHR2 mutation allele frequency of 0.16 and a carrier genotypic frequency of 0.27. The genetic basis for PMDS in the Belgian Malinois was not determined, as no coding or splicing mutations were identified in either AMH or AMHR2. These findings support a benefit to AMHR2 mutation testing Miniature Schnauzers used for breeding or with cryptorchidism.

AB - Most ignition and initiation systems nowadays still contain poisonous chemicals such as lead styphnate and lead azide but also chromates and other compounds of high concern. Therefore, methylsemicarbazide (1, MSC), which can be prepared in a one-step reaction and in an extraordinary high yield of 95 %, has been evaluated as ligand in energetic coordination compounds. For the first time 25 new transition metal complexes (Mn2+ , Ni2+ , Co2+ , Cu2+ , and Zn2+ ) using methylsemicarbazide (1) as the ligand were prepared and comprehensively analyzed by, for example, XRD, IR, EA, UV/Vis and DSC/DTA/TGA. Many show a strong energetic character, which can be tuned by using different anions such as Cl- , SO42- , NO3- , ClO4- , picrate or styphnate. Selected compounds were additionally evaluated as lead-free primary explosives in initiation tests (nitropenta filled detonators) and in laser ignition systems. Especially compound 7 showed very promising results during these tests and could be a potential candidate for future applications. PMID- 29194810 TI - Highly Multiplexed Single-Cell Protein Analysis. AB - Single-cell proteomic analysis is crucial to advance our understanding of normal physiology and disease pathogenesis. The comprehensive protein profiling in individual cells of a heterogeneous sample can provide new insights into many important biological issues, such as the regulation of inter- and intracellular signaling pathways or the varied cellular compositions of normal and diseased tissues. With highly multiplexed molecular imaging of many different protein biomarkers in patient biopsies, diseases can be accurately diagnosed to guide the selection of the ideal treatment. In this Minireview, we will describe the recent technological advances of single-cell proteomic assays, discuss their advantages and limitations, highlight their applications in biology and precision medicine, and present the current challenges and potential solutions. PMID- 29194811 TI - Organic-Inorganic Hybrid Materials: Multi-Functional Solids for Multi-Step Reaction Processes. AB - The design of new hybrid materials with tailored properties at the nano-, meso-, and macro-scale, with the use of structural functional nanobuilding units, is carried out to obtain specific multi-functional materials. Organization into controlled 1D, 2D, and 3D architectures with selected functionalities is key for developing advanced catalysts, but this is hardly accomplished using conventional synthesis procedures. The use of pre-formed nanostructures, derived either from known materials or made with specific innovative synthetic methodologies, has enormous potential in the generation of multi-site catalytic materials for one pot processes. The present concept article introduces a new archetype wherein self-assembled nanostructured builder units are the base for the design of multifunctional catalysts, which combine catalytic efficiency with fast reactant and product diffusion. The article addresses a new generation of versatile hybrid organic-inorganic multi-site catalytic materials for their use in the production of (chiral) high-added-value products within the scope of chemicals and fine chemicals production. The use of those multi-reactive solids for more nanotechnological applications, such as sensors, due to the inclusion of electron donor-acceptor structural arrays is also considered, together with the adsorption desorption capacities due to the combination of hydrophobic and hydrophilic sub domains. The innovative structured hybrid materials for multipurpose processes here considered, can allow the development of multi-stage one-pot reactions with industrial applications, using the materials as one nanoreactor systems, favoring more sustainable production pathways with economic, environmental and energetic advantages. PMID- 29194812 TI - Versatile cell surface structures of archaea. AB - Archaea are ubiquitously present in nature and colonize environments with broadly varying growth conditions. Several surface appendages support their colonization of new habitats. A hallmark of archaea seems to be the high abundance of type IV pili (T4P). However, some unique non T4 filaments are present in a number of archaeal species. Archaeal surface structures can mediate different processes such as cellular surface adhesion, DNA exchange, motility and biofilm formation and represent an initial attachment site for infecting viruses. In addition to the functionally characterized archaeal T4P, archaeal genomes encode a large number of T4P components that might form yet undiscovered surface structures with novel functions. In this review, we summarize recent advancement in structural and functional characterizations of known archaeal surface structures and highlight the diverse processes in which they play a role.

Metal-free C-H activation of branched aldehydes mediating the hydroacylation of electron deficient alkenes is an attractive transformation, but is limited by selectivity issues, especially in the case of alpha,alpha-disubstituted aldehydes. Herein, we report a green, cheap, versatile, and easily reproducible selective hydroacylation of alkenes utilizing phenylglyoxylic acid as the photocatalyst and common household bulbs for irradiation, leading to products in excellent yields and selectivities. The reaction mechanism was also studied to account for the high selectivity. PMID- 29194815 TI - The new Pan-American Neuroendocrine Society.

PMID- 29194816 TI - Programming Recognition Arrays through Double Chalcogen-Bonding Interactions. AB - In this work, we have programmed and synthesized a recognition motif constructed around a chalcogenazolo-pyridine scaffold (CGP) that, through the formation of frontal double chalcogen-bonding interactions, associates into dimeric EX-type complexes. The reliability of the double chalcogen-bonding interaction has been shown at the solid-state by X-ray analysis, depicting the strongest recognition persistence for a Te-congener. The high recognition fidelity, chemical and thermal stability and easy derivatization at the 2-position makes CGP a convenient motif for constructing supramolecular architectures through programmed chalcogen-bonding interactions. PMID- 29194817 TI - Porphyrin-Based Air-Stable Helical Radicals. AB - Stable helical radicals are promising multi-functional molecules in light of intriguing magnetic and chiroptical properties. Attempts were made to extend diphenylmethyl-fused NiII porphyrin radical to helical system as the first air stable organic neutral helical radicals. Intramolecular Pd-catalyzed twofold C-H arylation of methyl- or methoxy-introduced meso-diphenylmethyl NiII porphyrins gave a mixture of the target and rearranged radicals. Oxidative fusion reaction of meso-(bis(1-naphthyl)methyl) NiII porphyrins provided doubly fused NiII porphyrin radicals. One of the helical radicals was separated into enantiomers that showed mirror-image circular dichroism (CD) spectra up to 1300 nm. The helical dinaphthylmethyl-fused NiII porphyrin radical displayed solid-state magnetic property mostly arising from monomeric radicals, different from the parent diphenylmethyl-fused NiII porphyrin radical that showed antiferromagnetic coupling due to pi-stacked pairing. PMID- 29194818 TI - Rapid nongenomic modulation by neurosteroids of dendritic spines in the hippocampus: Androgen, oestrogen and corticosteroid. AB - Memories are stored in synapses that consist of axon terminals and dendritic spines. Dendritic spines are postsynaptic structures of synapses and are essential for synaptic plasticity and cognition. Therefore, extensive investigations concerning the functions and structures of spines have been performed. Sex steroids and stress steroids have been shown to modulate hippocampal synapses. Although the rapid modulatory action of sex steroids on synapses has been studied in hippocampal neurones over several decades, the essential molecular mechanisms have not been fully understood. Here, a description of kinase-dependent signalling mechanisms is provided that can explain the rapid nongenomic modulation of dendritic spinogenesis in rat and mouse hippocampal slices by the application of sex steroids, including dihydrotestosterone, testosterone, oestradiol and progesterone. We also indicate the role of synaptic (classic) sex steroid receptors that trigger these rapid synaptic modulations. Moreover, we describe rapid nongenomic spine modulation by applying corticosterone, which is an acute stress model of the hippocampus. The explanations for the results obtained are mainly based on the optical imaging of dendritic spines. Comparisons are also performed with results obtained from other types of imaging, including electron microscopic imaging. Relationships between spine modulation and modulation of cognition are discussed. We recognise that most of rapid effects of exogenously applied oestrogen and androgen were observed in steroid-depleted conditions, including acute slices of the hippocampus, castrated male animals and ovariectomised female animals. Therefore, the previously observed effects can be considered as a type of recovery event, which may be essentially similar to hormone replacement therapy under hormone-decreased conditions. On the other hand, in gonadally intact young animals with high levels of endogenous sex hormones, further supplementation of sex hormones might not be effective, whereas the infusion of blockers for steroid receptors or kinases may be effective, with respect to suppressing sex hormone functions, thus providing useful information regarding molecular mechanisms.

AB - We synthesized conjugated microporous polymers (CMPs) based on tetrakis(4 ethynylphenyl)stannane and diiodobenzene as tectons, using Sonogashira couplings under different conditions. Through variation of the reaction conditions (catalysts, bases and solvents), appearance, surface area and emission properties of the formed CMPs were significantly altered. Wet-chemical, acid-mediated digestion and analysis of the resulting struts of these otherwise insoluble networks give insight into the molecular setup. PMID- 29194820 TI - Evidence for Iron-Catalyzed alpha-Phosphinidene Elimination with Phenylphosphine. AB - The ubiquitous half-sandwich iron complex [CpFe(CO)2 Me] (Cp=eta5 -C5 H5 ) appears to be a catalyst for alpha-phosphinidene elimination from primary phosphines. Dehydrocoupling reactions provided initial insight into this unusual reaction mechanism, and trapping reactions with organic substrates gave products consistent with an alpha elimination mechanism, including a rare example of a three-component reaction. The substrate scope of this reaction is consistent with generation of a triplet phosphinidene. In all, this study presents catalytic phosphinidene transfer to unsaturated organic substrates. PMID- 29194822 TI - De Novo Synthesis of Benzannelated Heterocycles. AB - Benzannelated heterocycles such as indoles and indazoles are prominent structural motifs found in natural products, pharmaceuticals and agrochemicals. For their synthesis, chemists traditionally either functionalize commercially available heterocycles or resort to transformations that make use of benzene-derived building blocks. Here, we report a powerful cascade reaction that enables the de novo construction of variously substituted indoles, indazoles, benzofurans and benzothiophenes from readily available bicyclo[3.1.0]hexan-2-ones. The transformation can be conducted under mild, non-anhydrous conditions. For the synthesis of indoles, mechanistic studies revealed that the electrocyclic ring opening of the bicyclic ring-system and aromatization precedes the 3,3 sigmatropic rearrangement.

AB - The applications of three-dimensional superstructures that consist of metal organic framework (MOF) crystals are promising, but limited by spatial control over the crystallization process. Here a hydrophobic hierarchical metal-organic framework (HZIF-8) containing unusual micro-, meso-, and macropores was designed and synthesized by a template strategy, in which the polystyrene (PS) not only acted as the template to construct the macropores, but also modified the hydrophilic crystal surface of ZIF-8. When used as adsorbent for liquid oil/water separation, HZIF-8 demonstrated significantly enhanced oil adsorption performance while maintaining very low water uptake. PMID- 29194824 TI - Preparation of a Si/SiO2 -Ordered-Mesoporous-Carbon Nanocomposite as an Anode for High-Performance Lithium-Ion and Sodium-Ion Batteries. AB - In this work, an Si/SiO2 -ordered-mesoporous carbon (Si/SiO2 -OMC) nanocomposite was initially fabricated through a magnesiothermic reduction strategy by using a two-dimensional bicontinuous mesochannel of SiO2 -OMC as a precursor, combined with an NaOH etching process, in which crystal Si/amorphous SiO2 nanoparticles were encapsulated into the OMC matrix. Not only can such unique porous crystal Si/amorphous SiO2 nanoparticles uniformly dispersed in the OMC matrix mitigate the volume change of active materials during the cycling process, but they can also improve electrical conductivity of Si/SiO2 and facilitate the Li+ /Na+ diffusion. When applied as an anode for lithium-ion batteries (LIBs), the Si/SiO2 -OMC composite displayed superior reversible capacity (958 mA h g-1 at 0.2 A g-1 after 100 cycles) and good cycling life (retaining a capacity of 459 mA h g-1 at 2 A g-1 after 1000 cycles). For sodium-ion batteries (SIBs), the composite maintained a high capacity of 423 mA h g-1 after 100 cycles at 0.05 A g-1 and an extremely stable reversible capacity of 190 mA h g-1 was retained even after 500 cycles at 1 A g-1 . This performance is one of the best long-term cycling properties of Si-based SIB anode materials. The Si/SiO2 -OMC composites exhibited great potential as an alternative material for both lithium- and sodium-ion battery anodes. PMID- 29194825 TI - Drastic Effect of the Peptide Sequence on the Copper-Binding Properties of Tripeptides and the Electrochemical Behaviour of Their Copper(II) Complexes. AB - The binding and electrochemical properties of the complexes CuII -HAH, CuII -HWH, CuII -Ac-HWH, CuII -HHW, and CuII -WHH have been studied by using NMR and UV/Vis spectroscopies, CV, and density functional calculations. The results obtained highlight the importance of the peptidic sequence on the coordination properties and, consequently, on the redox properties of their CuII complexes. For CuII -HAH and CuII -HWH, no cathodic processes are observed up to -1.2 V; that is, the complexes exhibit very high stability towards copper reduction. This behaviour is associated with the formation of very stable square-planar (5,5,6)-membered chelate rings (ATCUN motif), which enclose two deprotonated amides. In contrast, for non-ATCUN CuII -Ac-HWH, CuII -HHW complexes, simulations seem to indicate that only one deprotonated amide is enclosed in the coordination sphere. In these cases, the main electrochemical feature is a reductive irreversible one electron transfer process from CuII to CuI , accompanied with structural changes of the metal coordination sphere and reprotonation of the amide. Finally, for CuII -WHH, two major species have been detected: one at low pH (<5), with no deprotonated amides, and another one at high pH (>10) with an ATCUN motif, both species coexisting at intermediate pH. The present study shows that the use of CV, using glassy carbon as a working electrode, is an ideal and rapid tool for the determination of the redox properties of CuII metallopeptides. PMID- 29194826 TI - Disentangling sex allocation in a viviparous reptile with temperature-dependent sex determination: a multifactorial approach. AB - Females are predicted to alter sex allocation when ecological, physiological and behavioural variables have different consequences on the fitness of male and female offspring. Traditionally, tests of sex allocation have examined single causative factors, often ignoring possible interactions between multiple factors. Here, we used a multifactorial approach to examine sex allocation in the viviparous skink, Niveoscincus ocellatus. We integrated a 16-year observational field study with a manipulative laboratory experiment to explore whether the effects of the maternal thermal environment interact with the resources available to females for reproduction to affect sex allocation decisions. We found strong effects of temperature on sex allocation in the field, with females born in warm conditions and males in cold conditions; however, this was not replicated in the laboratory. In contrast, we found no effect of female resource availability on sex allocation, either independently, or in interaction with temperature. These results corresponded with an overall lack of an effect of resource availability on any of the life history traits that we predicted would mediate the benefits of differential sex allocation in this system, suggesting that selection for sex allocation in response to resource availability may be relatively weak. Combined, these results suggest that temperature may be the predominant factor driving sex allocation in this system. PMID- 29194827 TI - Downregulation of lncRNA CASC2 facilitates osteosarcoma growth and invasion through miR-181a. AB - OBJECTIVES: Long non-coding RNA cancer susceptibility candidate 2 (CASC2) is a novel lncRNA and has been indicated as playing tumour suppressor gene in several tumours. However, the role of CASC2 in osteosarcoma is still uncovered. MATERIALS AND METHODS: The CASC2 and miR-181a expressions were measured via qRT-PCR. CCK-8 assay and colony formation assay were performed to determine the cell growth, and transwell assay was performed to assess the cell invasion. RESULTS: We showed that CASC2 expression was downregulated in osteosarcoma samples and cell lines. Moreover, we showed that downregulated expression of CASC2 was correlated with advanced TNM stage. Furthermore, overexpression of CASC2 inhibited osteosarcoma cell proliferation, colony formation, and invasion. In addition, we indicated that ectopic expression of CASC2 suppressed miR-181a expression and enhanced the expression of Ras association domain family member 6 (RASSF6), PTEN and ATM in osteosarcoma cell, which were the direct target gene of miR-181a. Moreover, we indicated that RASSF6 expression was downregulated in osteosarcoma samples and cell lines and downregulated expression of RASSF6 was correlated with advanced TNM stage. We found that the expression of RASSF6 was positively correlated with the expression of CASC2 in osteosarcoma tissues. Ectopic expression of CASC2 suppressed the osteosarcoma cell proliferation, colony formation and invasion through regulating RASSF6 expression. CONCLUSIONS: Our data illuminated that CASC2 acted as a tumour suppressor in osteosarcoma progression. PMID- 29194828 TI - Caught between a rock and a hard place: An intrinsic single case study of nurse researchers' experiences of the presence of a nursing research culture in clinical practice. AB - AIMS AND OBJECTIVES: To explore how nurse researchers in clinical positions experience the presence of a nursing research culture in clinical practice. BACKGROUND: Higher demands in the hospitals for increasing the quality of patient care engender a higher demand for the skills of health professionals and evidence based practice. However, the utilisation of nursing research in clinical practice is still limited. DESIGN: Intrinsic single case study design underlined by a constructivist perspective. METHODS: Data were produced through a focus group interview with seven nurse researchers employed in clinical practice in two university hospitals in Zealand, Denmark, to capture the intrinsic aspects of the concept of nursing research culture in the context of clinical practice. A thematic analysis was conducted based on Braun and Clarke's theoretical guideline. RESULTS: "Caught between a rock and a hard place" was constructed as the main theme describing how nurse researchers in clinical positions experience the presence of a nursing research culture in clinical practice. The main theme was supported by three subthemes: Minimal academic tradition affects nursing research; Minimal recognition from physicians affects nursing research; and Moving towards a research culture. CONCLUSIONS: The nurse researchers in this study did not experience the presence of a nursing research culture in clinical practice, however; they called for more attention on removing barriers against research utilisation, promotion of applied research and interdisciplinary research collaboration, and passionate management support. RELEVANCE TO CLINICAL PRACTICE: The results of this case study show the pressure which nurse researchers employed in clinical practice are exposed to, and give examples on how to accommodate the further development of a nursing research culture in clinical practice. PMID- 29194829 TI - On the helical arrangements of protein molecules. AB - Helical structures are prevalent in biology. In the PDB, there are many examples where protein molecules are helically arranged, not only according to strict crystallographic screw axes but also according to approximate noncrystallographic screws. The preponderance of such screws is rather striking as helical arrangements in crystals must preserve an integer number of subunits per turn, while intuition and simple packing arguments would seem to favor fractional helices. The article provides insights into such questions, based on stereochemistry, trigonometry, and topology, and illustrates the findings with concrete PDB structures. Updated statistics of Sohncke space groups in the PDB are also presented. PMID- 29194830 TI - Effect of Intraoral Mechanical Cleaning Techniques on Bond Strength of Cast Crowns to Metal Cores. AB - PURPOSE: To evaluate the effect of cleaning of metal cores from provisional cement, using an intraoral airborne-particle abrasion method, on the bond strength of permanent resin cement with cast crowns to cores. MATERIALS AND METHODS: Thirty stainless steel models of a standard complete crown tooth preparation were fabricated. Thirty Type III gold crowns were fabricated. Each cast crown corresponded to one stainless steel crown preparation model. All crowns were cemented with noneugenol zinc oxide cement and stored for 7 days at 37 degrees C. All crowns were debonded, and the cement was cleaned with airborne particle abrasion using 50 MUm aluminum oxide at 4.1 bar (0.41 MPa) followed by ultrasonic cleaning. Based on the mechanical cleaning technique of the remaining provisional cement on surfaces of cast cores, specimens were equally divided into 3 groups: hand cleaning (HC) with a dental excavator, hand cleaning followed by polishing using a brush and pumice (BP), and hand cleaning followed by intraoral airborne-particle abrasion (APA). All crowns were then cemented to their corresponding cores using universal resin cement. All crowns were stored for 7 days at 37 degrees C. An Instron universal testing machine was used to record the bond strength of crowns. RESULTS: Airborne-particle abrasion method for intraoral mechanical cleaning revealed a statistically significantly higher bond strength compared to the other two methods. CONCLUSIONS: When comparing the three methods of provisional cement cleaning from metal cores, airborne-particle abrasion resulted in the highest bond strength for cast crowns. PMID- 29194831 TI - Analysis of arrhythmic events is useful to detect lead failure earlier in patients followed by remote monitoring. AB - BACKGROUND: Remote monitoring (RM) has been advocated as the new standard of care for patients with cardiovascular implantable electronic devices (CIEDs). RM has allowed the early detection of adverse clinical events, such as arrhythmia, lead failure, and battery depletion. However, lead failure was often identified only by arrhythmic events, but not impedance abnormalities. OBJECTIVE: To compare the usefulness of arrhythmic events with conventional impedance abnormalities for identifying lead failure in CIED patients followed by RM. METHODS: CIED patients in 12 hospitals have been followed by the RM center in Okayama University Hospital. All transmitted data have been analyzed and summarized. RESULTS: From April 2009 to March 2016, 1,873 patients have been followed by the RM center. During the mean follow-up period of 775 days, 42 lead failure events (atrial lead 22, right ventricular pacemaker lead 5, implantable cardioverter defibrillator [ICD] lead 15) were detected. The proportion of lead failures detected only by arrhythmic events, which were not detected by conventional impedance abnormalities, was significantly higher than that detected by impedance abnormalities (arrhythmic event 76.2%, 95% CI: 60.5-87.9%; impedance abnormalities 23.8%, 95% CI: 12.1-39.5%). Twenty-seven events (64.7%) were detected without any alert. Of 15 patients with ICD lead failure, none has experienced inappropriate therapy. CONCLUSIONS: RM can detect lead failure earlier, before clinical adverse events. However, CIEDs often diagnose lead failure as just arrhythmic events without any warning. Thus, to detect lead failure earlier, careful human analysis of arrhythmic events is useful. PMID- 29194832 TI - The pathogenesis of paraesophageal empyema in dogs and constancy of radiographic and computed tomography signs are linked to involvement of the mediastinal serous cavity. AB - The mediastinal serous cavity is a normal anatomic space in the caudal mediastinum. Aims of this anatomic and case series study were to describe the signs of pathologic expansion of the mediastinal serous cavity observed during computed tomography (CT), review the underlying anatomy, perform a literature review, and evaluate the medical records of several dogs with mediastinal serous cavity empyema (paraesophageal empyema). The mesothelial lined mediastinal serous cavity is a cranial extension of the omental bursa, separated from the peritoneal cavity by the diaphragm, in the dorsal part of the caudal mediastinum, to the right of the esophagus, between the heart base and diaphragm. In five adult, large-breed dogs with surgically and histologically confirmed paraesophageal empyema, macroscopic plant material was found at surgery in two dogs, adherence to adjacent lung was present in three different dogs, accessory lobectomy was performed in two dogs with subacute-chronic pyogranulomatous pneumonia, and one dog had concurrent pyothorax and mediastinitis, but none had esophageal abnormalities. This study expands our understanding of the pathogenesis and basis for the imaging appearance of paraesophageal empyema in dogs by clarifying the underlying anatomic structures that direct development of this condition. The term empyema accurately describes this condition because the purulent material accumulates within an existing body cavity. The study also provides initial evidence that the development of paraesophageal empyema might be due to local extension of lung disease, such as foreign body migration or pneumonia. Computed tomography was helpful for diagnosis, assessing size, and determining the spread of disease. PMID- 29194833 TI - Mutations in COQ8B (ADCK4) found in patients with steroid-resistant nephrotic syndrome alter COQ8B function. AB - Mutations in COQ8B cause steroid-resistant nephrotic syndrome with variable neurological involvement. In yeast, COQ8 encodes a protein required for coenzyme Q (CoQ) biosynthesis, whose precise role is not clear. Humans harbor two paralog genes: COQ8A and COQ8B (previously termed ADCK3 and ADCK4). We have found that COQ8B is a mitochondrial matrix protein peripherally associated with the inner membrane. COQ8B can complement a DeltaCOQ8 yeast strain when its mitochondrial targeting sequence (MTS) is replaced by a yeast MTS. This model was employed to validate COQ8B mutations, and to establish genotype-phenotype correlations. All mutations affected respiratory growth, but there was no correlation between mutation type and the severity of the phenotype. In fact, contrary to the case of COQ2, where residual CoQ biosynthesis correlates with clinical severity, patients harboring hypomorphic COQ8B alleles did not display a different phenotype compared with those with null mutations. These data also suggest that the system is redundant, and that other proteins (probably COQ8A) may partially compensate for the absence of COQ8B. Finally, a COQ8B polymorphism, present in 50% of the European population (NM_024876.3:c.521A > G, p.His174Arg), affects stability of the protein and could represent a risk factor for secondary CoQ deficiencies or for other complex traits. PMID- 29194834 TI - Lipid-DNAs as Solubilizers of mTHPC. AB - Hydrophobic drug candidates require innovative formulation agents. We designed and synthesized lipid-DNA polymers containing varying numbers of hydrophobic alkyl chains. The hydrophobicity of these amphiphiles is easily tunable by introducing a defined number of alkyl chain-modified nucleotides during standard solid-phase synthesis of DNA using an automated DNA synthesizer. We observed that the resulting self-assembled micelles solubilize the poorly water-soluble drug, meta-tetra-hydroxyphenyl-chlorin (mTHPC) used in photodynamic therapy (PDT) with high loading concentrations and loading capacities. A cell viability study showed that mTHPC-loaded micelles exhibit good biocompatibility without irradiation, and high PDT efficacy upon irradiation. Lipid-DNAs provide a novel class of drug delivery vehicle, and hybridization of DNA offers a potentially facile route for further functionalization of the drug-delivery system with, for instance, targeting or imaging moieties. PMID- 29194836 TI - A Digital Approach to Retrofitting a Post and Core Restoration to an Existing Crown. AB - One problem that may arise in full-coverage restorations is clinical crown fracture. Fracture of an endodontically treated and crowned tooth in the esthetic zone may be embarrassing to both the patient and clinician. If a completely sound margin and at least 2 mm of coronal structure remain, a fractured tooth may possibly be retreated by a repair. Several methods have been introduced to reproduce the original contour of the tooth for retrofitting an existing crown. If an existing crown is used as a template, excessive core material may remain over the margin, as loading the proper amount of core material is difficult, and making vent holes on the existing crown is not feasible. This article presents a repair technique to reuse an existing crown with computer-aided design and computer-aided manufacturing (CAD/CAM) technology. By using a milled poly(methylmethacrylate) matrix, the mentioned limitations are eliminated, and the original contour of the tooth can be effectively restored with minimal intervention. As an existing crown is reused, the issues of additional time and cost for repreparation, reimpression, and new crown are eliminated. PMID- 29194837 TI - Substantial effects of empowerment case management on physical health of type 2 diabetic patients. AB - AIMS AND OBJECTIVES: To evaluate the effects of empowerment case management on the physical health of patients with type 2 diabetes. BACKGROUND: Diabetes is a global health issue. Case management is often used on diabetes management at various levels. Empowerment has been used for chronic situation management, but its effects have not been widely studied in diabetic populations. DESIGN: Purposive sampling was used to recruit 125 participants with type 2 diabetes aged 18 years or older from a regional teaching hospital in Taiwan. METHODS: Empowerment case management was applied for 42 participants, while the other 83 received normal case management. Survey items included demographics, preprandial (AC) and postprandial (PC) blood sugar levels, glycated haemoglobin (HbA1C), systolic and diastolic blood pressure, total cholesterol, and the presence or absence of acute and chronic complications. Descriptive statistics and a generalised estimating equation were used to analyse the model's effects on the two groups. RESULTS: The PC blood sugar levels of patients receiving empowerment case management declined at 3 months (B = -34.26, p < .01), and this decrease was maintained at 6 months (B = -83.66, p < .001). As of 6 months after starting the intervention, patients receiving empowerment case management enjoyed better physical health. These patients' AC blood sugar levels (B = -50.16, p < .001), HbA1C (B = -0.98, p < .001), systolic blood pressure (B = -8.24, p < .001), diastolic blood pressure (B = -5.73, p < .01) and total cholesterol (B = -13.74, p < .05) all experienced a continuous drop and were controlled well, and no diabetes-related acute or chronic complications were observed either. Patients with type 2 diabetes who received empowerment case management managed their physical health better. Moreover, its greatest effect was that patients were able to form exercise groups and continue to maintain their health. CONCLUSIONS: Empowerment case management was shown to have a substantial effect on the physical health and self-care of patients with diabetes, thus making it a suitable intervention tool for managing diabetes cases. RELEVANCE TO CLINICAL PRACTICE: The study results showed that empowerment case management is suitable for managing diabetes cases. It has a substantial effect on the maintenance of physical health, occurrence of complications and effectiveness of self-care among patients with diabetes. For better care outcomes, empowerment case management should be integrated into the guidelines of diabetes management.

AB - The innate immune system has evolved to play an integral role in the normally developing lung and brain. However, in response to oxidative stress, innate immunity, mediated by specific cellular and molecular programs and signaling, contributes to pathology in these same organ systems. Despite opposing drivers of oxidative stress, namely hyperoxia in neonatal lung injury and hypoxia/ischemia in neonatal brain injury, similar pathways-including toll-like receptors, NFkappaB and MAPK cascades-have been implicated in tissue damage. In this review, we consider recent insights into the innate immune response to oxidative stress in both neonatal and adult models to better understand hyperoxic lung injury and hypoxic-ischemic brain injury across development and aging. These insights support the development of targeted immunotherapeutic strategies to address the challenge of harnessing the innate immune system in oxidative stress diseases of the neonate. PMID- 29194838 TI - Reversible Modulation of Elasticity in Fluoroazobenzene-Containing Hydrogels Using Green and Blue Light. AB - Hydrogels are soft materials that have found multiple applications in biomedicine and represent a good platform for the introduction of molecular switches and synthetic machines into macromolecular networks. Tuning their mechanical properties reversibly with light is appealing for a variety of advanced applications and has been demonstrated in the past; however, their activation typically requires the use of UV light, which displays several drawbacks related to its damaging character and limited penetration in tissues and materials. This study circumvents this limitation by introducing all-visible ortho fluoroazobenzene switches into a hydrophilic network, which, as a result, can be activated with green or blue light. Photoisomerization of the photochromic moieties is accompanied by a reversible tuning of the elastic modulus. The translation of molecular isomerization within the network into macroscopic modulation of its mechanical properties is attributed to different aggregation tendencies of the E and Z isomers of the azobenzene derivatives. PMID- 29194839 TI - Analysis of the ectoenzymes ADA, ALP, ENPP1, and ENPP3, in the contents of ovarian endometriomas as candidate biomarkers of endometriosis. AB - PROBLEM: The diagnosis of endometriosis, a prevalent chronic disease with a strong inflammatory component, is usually delayed due to the lack of noninvasive diagnostic tests. Purinergic signaling, a key cell pathway, is altered in many inflammatory disorders. The aim of the present work was to evaluate the levels of adenosine deaminase (ADA), alkaline phosphatase (ALP), ecto-nucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), and ENPP3, elements of purinergic signaling, as biomarker candidates for endometriosis. METHOD OF STUDY: A case control comparative study was conducted to determine ADA, ALP, ENPP1 and ENPP3 levels in echo-guided aspirated fluids of endometriomas (case group) and simple ovarian cysts (control group) using the ELISA technique. RESULTS: Adenosine deaminase, ALP, ENPP1, and ENPP3 were present and quantifiable in the contents of endometriomas and simple cysts. There were significant differences in ADA and ENPP1 levels in endometriomas in comparison with simple cysts (2787 U/L and 103.9 ng/mL more in endometriomas, for ADA and ENPP1, respectively). Comparisons of ALP and ENPP3 levels between the two groups did not reveal significant differences. CONCLUSION: The ectoenzymes ADA and ENPP1 are biomarker candidates for endometriosis.

AB - PURPOSE: Intraoral digital scanning can accurately record single abutment tooth preparations despite their geometry, and the algorithms of the CAD software can be set to manage different abutment forms. The purpose of this in vitro study was to evaluate the marginal and internal fit of CAD/CAM zirconia crowns fabricated over conventional and reverse-tapered preparations. MATERIALS AND METHODS: Crown preparations with known total occlusal convergence (TOC) angles (-8 degrees , -4 degrees , 0 degrees , 8 degrees , 12 degrees , 16 degrees , and 22 degrees ) were digitally created from a maxillary left central incisor and printed in acrylic resin. Next, casts were scanned with a TRIOS intraoral scanner, and crowns were designed with KaVo multiCAD software using default parameters (50 MUm cement space) on abutments with positive TOC angles, whereas reverse-tapered abutments (negative TOC angles) were digitally blocked out at 0 degrees and had an extra mesiodistal gap set to 50 MUm. Then, zirconia crowns were fabricated, and their marginal and internal discrepancies were recorded with the silicone replica technique. All replicas were examined under a stereomicroscope at 50* magnification. Collected data were analyzed with one-way ANOVA and post hoc Tukey test for marginal fit. For the axial and incisal fit, measured values did not follow a normal distribution; therefore, the Kruskal-Wallis and the Dunn/Bonferroni multiple comparison tests were applied (p = 0.05). RESULTS: The mean marginal fit of -8 degrees crowns (58.2 +/- 6.0 MUm) was statistically different (p < 0.0001) from all the remaining crowns (range 42.1-47.3 MUm). Also, the internal fit was statistically significant when comparing crowns fabricated over abutments with positive and negative TOC angles (p < 0.0001). The largest median axial discrepancies were found in the -8 degrees (165.5 MUm) and -4 degrees (130.8 MUm) groups; however, when evaluating the incisal fit, they showed the smallest discrepancies (67.3 and 81.8 MUm, respectively). CONCLUSIONS: Under the conditions of this study, the marginal and internal fit of zirconia crowns fabricated over inverse-tapered preparations is within clinically accepted values. PMID- 29194840 TI - Parasites favour intermediate nestling mass and brood size in cliff swallows. AB - A challenge of life-history theory is to explain why animal body size does not continue to increase, given various advantages of larger size. In birds, body size of nestlings and the number of nestlings produced (brood size) have occasionally been shown to be constrained by higher predation on larger nestlings and those from larger broods. Parasites also are known to have strong effects on life-history traits in birds, but whether parasitism can be a driver for stabilizing selection on nestling body size or brood size is unknown. We studied patterns of first-year survival in cliff swallows (Petrochelidon pyrrhonota) in western Nebraska in relation to brood size and nestling body mass in nests under natural conditions and in those in which hematophagous ectoparasites had been removed by fumigation. Birds from parasitized nests showed highest first-year survival at the most common, intermediate brood-size and nestling-mass categories, but cliff swallows from nonparasitized nests had highest survival at the heaviest nestling masses and no relationship with brood size. A survival analysis suggested stabilizing selection on brood size and nestling mass in the presence (but not in the absence) of parasites. Parasites apparently favour intermediate offspring size and number in cliff swallows and produce the observed distributions of these traits, although the mechanisms are unclear. Our results emphasize the importance of parasites in life-history evolution. PMID- 29194842 TI - Mother's level of confidence in caring for her late preterm infant: A mixed methods study. AB - AIM AND OBJECTIVES: To examine what it means to be a mother of a late preterm infant including a mother's level of confidence in caring for her late preterm infant over time and the effect of maternal depression of this experience. BACKGROUND: Little is known about mothers' experiences of caring for their late preterm infants in the community, including their level of confidence and parenting stress within the context of a supported care environment by public health nurses. DESIGN: A mixed methods study, sequential explanatory quantitative and qualitative study. METHODS: A convenience sample of mothers with LPIs (n = 71) completed questionnaires on maternal confidence (3-4 weeks and 6-8 weeks), parenting stress (6-8 weeks), social support (6-8 weeks) and postpartum depression (6-8 weeks). A purposive sample of mothers (n = 11) underwent in depth, semi-structured interviews. RESULTS: Maternal confidence decreased from 3 4 weeks-6-8 weeks after delivery, and similar results were found for mothers who reported depressive symptoms. Narratives of the mothers suggested the decrease in maternal confidence over time was influenced by the demanding characteristics of the late preterm infant, the prospect of their rehospitalisation and the mother's reported interactions with public health nurses. Depression had an effect on maternal confidence; that is, the depressed mothers demonstrated less confidence about their caretaking role than the nondepressed mothers at 6-8 weeks. Mothers did not discuss mental health issues, which may reflect the protective effects of social support on emotional instability or an inability to recognise postpartum depression. CONCLUSION: The confidence of mothers with LPIs decreased over the first 2 months following delivery and being home with their infants. Assisting mothers to meet their personal needs and the needs of their infant should promote maternal skills, which will likely increase maternal confidence related to the care of their late preterm infant. RELEVANCE FOR CLINICAL PRACTICE: Characteristics of LPIs contributed more to parenting stress score than parent characteristics; mothers however attempted to normalise the late preterm infant in order to minimise the parenting stress. Evidence-informed brief interventions tailored based on late preterm infant and parent characteristics may improve maternal confidence over time. Healthcare professional should provide education and anticipatory guidance prior to discharge, consistent care in hospital and postdischarge as this may impact maternal level of confidence. Future research needs to examine standards of care for discharge of LPIs and adherence to these standards.

AB - New 1,7-closo-carboranylanilinoquinazoline hybrids have been identified as EGFR inhibitors, one of them with higher affinity than the parent compound erlotinib. The comparative docking analysis with compounds bearing bioisoster-substructures, demonstrated the relevance of the 3D aromatic-boron-rich moiety for interacting into the EGFR ATP binding region. The capability to accumulate in glioma cells, the ability to cross the blood-brain barrier and the stability on simulated biological conditions, render these molecules as lead compounds for further structural modifications to obtain dual action drugs to treat glioblastoma.

PMID- 29194844 TI - Older Brazilian caregivers and their lived experiences of caring-A hermeneutic phenomenological study. AB - AIMS AND OBJECTIVES: To understand the lived experiences of older Brazilian carers. BACKGROUND: For many caregivers, the practice of caregiving becomes their daily lives, embedding in their care and the experiences, beliefs, learning and techniques that contribute to the meanings these caregivers attach to their world. Studies have reported on the experiences of caregivers in general; however, few studies have addressed the unique characteristics of older caregivers. METHOD: Phenomenological research was conducted in the homes of these persons who were registered in a public programme of home care. This study utilised recorded interviews with a guiding question and roadmap for characterisation. The transcribed interviews were analysed based on philosophical hermeneutics and on the understanding of the hermeneutic circle. The units of meaning were discussed from the perspective of Heidegger's phenomenology. RESULTS: Six older primary caregivers participated, aged between 62-84 years. The following units of meaning were developed: the daily life of being in the world as an older person caring for another older person, the historicity and their disclosedness to the world of care. CONCLUSIONS: The worldliness of these people is influenced by a taxing routine and being overloaded and lonely, which renders these caregivers vulnerable because of this routine and because of the inherent weaknesses induced by the ageing process. RELEVANCE TO CLINICAL PRACTICE: This research can help health professionals better understand the worldliness of older caregivers. Such understanding will enhance the assistance available to caregivers, which must extend beyond the care of the sick person: interventions can reduce their overburden and risk of illness, improving their experiences as caregivers and their quality of life. PMID- 29194846 TI - Supply-side effects from public insurance expansions: Evidence from physician labor markets. AB - Medicaid and the Child Health Insurance Programs (CHIP) are key sources of coverage for U.S. children. Established in 1997, CHIP allocated $40 billion of federal funds across the first 10 years but continued support required reauthorization. After 2 failed attempts in Congress, CHIP was finally reauthorized and significantly expanded in 2009. Although much is known about the demand-side policy effects, much less is understood about the policy's impact on providers. In this paper, we leverage a unique physician dataset to examine if and how pediatricians responded to the expansion of the public insurance program. We find that newly trained pediatricians are 8 percentage points more likely to subspecialize and as much as 17 percentage points more likely to enter private practice after the law passed. There is also suggestive evidence of greater private practice growth in more rural locations. The sharp supply-side changes that we observe indicate that expanding public insurance can have important spillover effects on provider training and practice choices. PMID- 29194847 TI - Clinical evaluation of the multifunctional suprapubic catheter in patients requiring permanent suprapubic cystostomy: a prospective randomized trial in a single center. AB - AIMS AND OBJECTIVES: To assess the clinical effect of the multifunctional suprapubic catheter (MSC) on occurrence of cystospasm, catheter occlusion, the catheter-related urinary tract infection and remission of over-activity bladder, by comparing with the conventional suprapubic catheter (CSC) in patients with permanent suprapubic cystostomy. BACKGROUND: The conventional suprapubic catheter usually presents with high incidence of catheter-associated complications. DESIGN: A prospective randomized clinical trial in a single-center. METHODS: Between Jan 2014 and Jan 2015, a total of 91 consecutive patients with permanent suprapubic cystostomy were prospectively randomized into two groups: the MSC group (n = 43) and CSC group (n = 48). RESULTS: Our results showed that the total times of cystospasm in the MSC group were significantly less than that in the CSC group during the follow-up time (p < 0.001). In addition, the mean spasmodic duration per time in the MSC group was significantly shorter than that in the CSC group (p < 0.001). Besides, catheter occlusions were observed in 23 (25.27%) patients, including 5 (11.63%) in the MSC group and 18 (37.50%) in the CSC group (p = 0.005). The lower rate of positive urine culture was also found in the MSC group but with no significant difference (p = 0.540). Furthermore, the urodynamic measurement data demonstrated that the patients in the MSC group had a greater remission rate of over-activity bladder after catheter change (p < 0.001). CONCLUSIONS: The present data showed that the multifunctional suprapubic catheter could significantly reduce the incidence of catheter occlusion, ameliorate the symptom of cystospasm and relieve the over-activity bladder, but have no influence on the catheter-related urinary tract infection.

PMID- 29194848 TI - Natural regulatory IgM-mediated autoimmune responses directed against malondialdehyde regulate oxidative and nitrosative pathways and coupled with IgM responses to nitroso adducts attenuate depressive and physiosomatic symptoms at the end of term pregnancy. AB - AIM: We aimed to delineate the effects of immunoglobulin (Ig)M-mediated autoimmune responses directed against malondialdehyde (MDA) and nitroso (SNO) adducts on nitro-oxidative stress and depressive and physiosomatic symptoms (DPSS) at the end of term. METHODS: IgM responses to MDA, NO (nitroso) adducts formed by nitrosylation, and NO2 tyrosine formed by nitration were measured as well as hydroperoxides (ferrous oxidation xylenol orange), advanced protein oxidation products (AOPP), and NO metabolite (NOx) levels in women at the end of term pregnancy and in normal controls. RESULTS: IgM responses to MDA were significantly and inversely associated with AOPP, ferrous oxidation xylenol orange, and NOx and DPSS. IgM responses to NO adducts were significantly and inversely associated with DPSS and positively with NOx levels. There were significant associations between IgM responses to MDA, NO adducts, and NO2 tyrosine. The DPSS score was predicted by AOPP and a lifetime history of premenstrual syndrome (both positively) and IgM responses to NO adducts (inversely). Furthermore, 71.8% of the variance in the index of nitro-oxidative stress was explained by lowered IgM responses to MDA, antioxidant levels (zinc, total radical trapping parameter), and inflammatory mediators. CONCLUSION: Lowered levels of IgM responses to MDA during pregnancy are accompanied by a reduced regulation of nitro-oxidative processes thereby explaining increased oxidative and nitrosative stress biomarkers in association with DPSS. IgM responses to NO adducts, which reflect nitrosylation as a consequence of increased NO production, regulate DPSS symptoms at the end of term and are a trait marker of major depression. IgM responses to MDA are a key part of the compensatory anti-inflammatory responses system. PMID- 29194849 TI - Somatotopic effects of rTMS in neuropathic pain? A comparison between stimulation over hand and face motor areas. AB - BACKGROUND: The therapeutic influence of somatotopic matching between pain topography and motor cortex stimulation site for neuropathic pain (NP) remains controversial. METHODS: Thirty-two patients suffering from NP involving the upper limb (n = 20) or the face (n = 12) received two high-frequency rTMS neuronavigated sessions targeting hand and face motor cortical areas, versus placebo. The cortical target was defined by anatomical MRI and EMG responses in all patients, completed in 19 of them by functional MRI. Sessions were separated by at least 2 weeks and applied in random order. Pain relief was assessed using numerical rating scale (NRS). RESULTS: In terms of percentage of pain relief, rTMS over the hand motor area was significantly superior to both face rTMS and placebo. When comparing pre- and post-NRS scores, a significant decrease in pain was observed after hand area rTMS for the two pain localizations, while stimulation of the face area induced a slight but nonsignificant effect on upper limb pain after correction. Sham-rTMS did not exert any effect. The percentage of patients with clinically significant (>30%) or mild (15-30%) pain relief did not differ, however, between rTMS addressed to the hand or face area. CONCLUSIONS: The results do not support a somatotopic effect of motor rTMS for NP. Lack of clinically relevant somatotopic effects in upper limb or face pain suggests that much of the rTMS analgesic effect may depend on high-order mechanisms involving cognitive and affective appraisal of pain, rather than on a sensory effect related to the specific motor area stimulated. SIGNIFICANCE: Strict somatotopic targeting of rTMS does not appear warranted for the treatment of upper limb or face NP. Since the hand motor area is easier to target and provides better results, it might be privileged for both types of pain. PMID- 29194850 TI - The third person in the room: The needs of care partners of older people in home care services-A systematic review from a person-centred perspective. AB - AIMS AND OBJECTIVES: To identify and synthesise the needs of care partners of older people living at home with assistance from home care services. BACKGROUND: "Ageing in place" is a promoted concept where care partners and home care services play significant roles. Identifying the needs of care partners and finding systematic ways of meeting them can help care partners to cope with their role. DESIGN/METHODS: This study is based on the PRISMA reporting guidelines. The systematic review of qualitative and quantitative studies was guided by the Joanna Briggs Institute methodology. RESULTS: In total, 16 studies were included in the review, eleven qualitative and five quantitative. Three main categories were revealed in the analysis: the need for quality interaction, the need for a shared approach to care and the need to feel empowered. CONCLUSION: Care partners of older people have several, continuously unmet needs. A person-centred perspective can contribute new understandings of how to meet these needs. A knowledge gap has been identified regarding the needs of care partners of older people with mental health problems. There is a need to develop a tool for systematic collaboration between home care services and care partners, so that the identified needs can be met in a more thorough, systematic and person-centred way. RELEVANCE TO CLINICAL PRACTICE: The carers in home care services need competence to identify and meet the needs of care partners. The implementation of person-centred values in home care services can contribute to meet the needs of care partners to a greater extent than today. Future research on the needs of care partners of older people with mental health problems needs to be undertaken. PMID- 29194851 TI - Superiority of capsaicin 8% patch versus oral pregabalin on dynamic mechanical allodynia in patients with peripheral neuropathic pain. AB - BACKGROUND: Dynamic Mechanical Allodynia (DMA) is a typical symptom of neuropathic pain (NP). In a recent study, the capsaicin 8% patch was noninferior to pregabalin in overall peripheral NP relief. In this study, we report the comparison of the two treatments in relieving DMA. METHODS: In a randomized, open label, head-to-head, 8-week study, 488 patients with peripheral NP were treated with the capsaicin 8% patch (one application) or an optimized dose of pregabalin. Assessments included the area and intensity of DMA, and the number of patients achieving complete resolution of DMA. RESULTS: At baseline, 253 patients in the capsaicin 8% patch group and 235 patients in the pregabalin group had DMA. From baseline to end of study, the change in DMA intensity was significantly in favour of the capsaicin 8% patch versus pregabalin [-0.63 (95% CI: -1.04, -0.23; p = 0.002)]. Similarly, the capsaicin 8% patch was superior to pregabalin in reducing the area of DMA [-39.5 cm2 (95% CI: -69.1, -10.0; p = 0.009)] from baseline to end of study. Overall, a greater proportion of patients had a complete resolution of allodynia with capsaicin 8% patch treatment compared with pregabalin treatment (24.1% vs. 12.3%; p = 0.001) at end of study. CONCLUSION: Capsaicin 8% treatment was superior to pregabalin in reducing the intensity and area of DMA, and in the number of patients with complete resolution of DMA. SIGNIFICANCE: The superiority of a topical treatment over pregabalin in relieving DMA supports the view that both peripheral and central sensitization can mediate allodynia. PMID- 29194852 TI - The role of sclerostin/dickkopf-1 and receptor activator of nuclear factor kB ligand/osteoprotegerin signalling pathways in the development of osteoporosis in patients with haemophilia A and B: A cross-sectional study. AB - AIM: Haemophilia A and B are associated with reduced bone mineral density (BMD). The aim of this study was to assess circulating sclerostin and dickkopf-1 (Dkk 1), (inhibitors of osteoblastic differentiation), as well as the receptor activator of nuclear factor kB ligand (RANKL)/osteoprotegerin (OPG) system (the major regulator of osteoclastogenesis), in patients with haemophilia (PWH), their possible correlations with clinical risk factors and the effect of ibandronate on these markers. METHODS: Eighty-nine male PWH (mean age 45.9 +/- 15.3 years) and 30 age-matched healthy male controls participated. BMD was assessed by DXA. Sclerostin, Dkk-1, RANKL and OPG were measured in serum of patients, controls, as well as in ten patients receiving oral ibandronate (150 mg/mo), at baseline and after 12 months. RESULTS: Patients with haemophilia had lower circulating sclerostin (median +/- IQR: 47.4 +/- 26.93 vs 250 +/- 250 pmol/L, P < .001), Dkk 1 (21.24 +/- 17.18 vs 26.16 +/- 15.32pg/mL, P = .04) and higher levels of RANKL (0.23 +/- 0.03 vs 0.04 +/- 0.03 pmol/L, P = .001), RANKL/OPG ratio (0.063 +/- 0.25 vs 0.005 +/- 0.11, P = .001) compared with controls. Patients with low BMD had higher OPG concentrations compared to those with normal BMD. Sclerostin and RANKL/OPG correlated positively with BMD. Patients with severe haemophilia had lower sclerostin concentrations compared with those with mild or moderate disease. The degree of arthropathy negatively correlated with sclerostin and Dkk 1 levels. PWH who received ibandronate showed a decrease in serum Dkk-1 without any significant effect on sclerostin and RANKL/OPG. CONCLUSIONS: Patients with haemophilia present increased osteoclastic activity coupled with compensatory increased osteoblastic activity. Ibandronate did not affect RANKL/OPG ratio, but it decreased Dkk-1. PMID- 29194853 TI - Report on the 2nd European Tissue Repair Society summer school, Brussels, September 11-12th, 2017. PMID- 29194854 TI - Vessel noise cuts down communication space for vocalizing fish and marine mammals. AB - Anthropogenic noise across the world's oceans threatens the ability of vocalizing marine species to communicate. Some species vocalize at key life stages or whilst foraging, and disruption to the acoustic habitat at these times could lead to adverse consequences at the population level. To investigate the risk of these impacts, we investigated the effect of vessel noise on the communication space of the Bryde's whale Balaenoptera edeni, an endangered species which vocalizes at low frequencies, and bigeye Pempheris adspersa, a nocturnal fish species which uses contact calls to maintain group cohesion while foraging. By combining long term acoustic monitoring data with AIS vessel-tracking data and acoustic propagation modelling, the impact of vessel noise on their communication space was determined. Routine vessel passages cut down communication space by up to 61.5% for bigeyes and 87.4% for Bryde's whales. This influence of vessel noise on communication space exceeded natural variability for between 3.9 and 18.9% of the monitoring period. Additionally, during the closest point of approach of a large commercial vessel, <10 km from the listening station, the communication space of both species was reduced by a maximum of 99% compared to the ambient soundscape. These results suggest that vessel noise reduces communication space beyond the evolutionary context of these species and may have chronic effects on these populations. To combat this risk, we propose the application or extension of ship speed restrictions in ecologically significant areas, since our results indicate a reduction in sound source levels for vessels transiting at lower speeds. PMID- 29194855 TI - Regarding Wellness and Burnout Initiatives in Emergency Medicine. PMID- 29194856 TI - Toronto Clinical Neuropathy Score is valid for a wide spectrum of polyneuropathies. AB - BACKGROUND AND PURPOSE: The Toronto Clinical Neuropathy Score (TCNS) is a valid and reliable scale for the diagnosis and staging of diabetic sensorimotor polyneuropathy. In this study, we aimed to explore the performance of the TCNS in non-diabetic polyneuropathies. METHODS: We performed a prospective study from November 2016 to May 2017 of patients with non-diabetic polyneuropathy. Patients had clinical, electrophysiological and functional assessments of their polyneuropathy, and the findings were correlated with the TCNS. RESULTS: The TCNS correlated with all clinical, electrophysiological and disability measures of polyneuropathy, mostly at a moderate level (e.g. r = -0.58 for sural nerve action potential amplitude). Higher TCNS severity grades were associated with worse polyneuropathy on all measures in the lower limbs, and with worse electrophysiological parameters and vibration perception thresholds in the upper limbs. The scale also showed excellent reliability and accuracy (kappa, 0.92-0.93 for inter- and intra-observer reliability; area under the receiver operating characteristics curve, 0.93). CONCLUSION: The TCNS is a valid and reliable scale for a wide spectrum of polyneuropathies, and might be useful in clinical practise and research for the diagnosis and staging of polyneuropathy.

AB - A four-year-old female French bulldog was presented for evaluation of acute, left sided peripheral vestibular syndrome. Computed tomographic (CT) examination of the head revealed the presence of air within the left cochlea and vestibule, consistent with pneumolabyrinth. This was concurrent with ipsilateral otitis media and externa. Pneumolabyrinth is an uncommon finding in humans and is most frequently due to head trauma and temporal bone fracture. This is the first report describing pneumolabyrinth in a dog, apparently of nontraumatic origin in this case. PMID- 29194859 TI - A nationwide epidemiological study of myasthenia gravis in Latvia. AB - BACKGROUND AND PURPOSE: Myasthenia gravis (MG) is an autoimmune disorder characterized by fatigable muscle weakness due to antibody-mediated impairment of neuromuscular transmission. The aim of this study was to investigate the incidence and prevalence of MG in Latvia, and to characterize this population by well-established clinical parameters such as age at onset, presence of associated antibodies and thymus pathology. METHODS: All prevalent cases on 1 January 2015 and cases of patients newly presenting with MG symptoms from 1 January 2010 to 31 December 2014 were selected from the database of the Neuromuscular Disease Clinic of Pauls Stradins Clinical University Hospital and Children's Clinical University Hospital. Crude rates were calculated based on population data. These were directly age-standardized to the European and World Health Organization world standard populations. The analysis of clinical characteristics was carried out in a cohort of patients who had undergone a complete set of electrophysiological, serological and radiological investigations (n = 153; 68%). RESULTS: During the study period 99 incident and 226 prevalent cases were identified. The total crude MG incidence was 9.7 per million person-years. The prevalence of MG on 1 January 2015 was 113.8 per million. 54.2% of patients tested positive for acetylcholine receptor antibodies, 7.8% for muscle specific kinase antibodies and 1.3% for lipoprotein related protein 4 antibodies. CONCLUSIONS: This is the first study of MG in Latvia and the second population-based study of MG in Eastern Europe. Our epidemiological results are similar to those in some other European and Northern American countries, and show high prevalence and increasing incidence of late onset MG. PMID- 29194858 TI - Low incidence of hepatitis B virus reactivation and subsequent hepatitis in patients with chronic hepatitis C receiving direct-acting antiviral therapy. AB - To determine the clinical characteristics of hepatitis B virus (HBV) reactivation in patients undergoing interferon-free antihepatitis C virus (HCV) therapy, we examined HBV DNA in 25 HBV co-infected patients and 765 patients with resolved HBV infection during and after treatment with direct-acting antiviral agents (DAAs). Among those with HCV genotype 1, asunaprevir plus daclatasvir was administered to 160 patients, sofosbuvir (SOF) plus ledipasvir to 438 patients and paritaprevir plus ombitasvir and ritonavir to 25 patients. In total, 167 patients with genotype 2 were treated with SOF plus ribavirin. Three patients with an HBV DNA level >=2000 IU/mL were treated with entecavir before anti-HCV therapy, without reactivation of HBV. In 3 of 22 (12%) HBV surface antigen (HBsAg)-positive patients with an HBV DNA level <2000 IU/mL, the viral load increased during treatment. However, hepatitis flare did not occur in these patients. There was no significant difference in clinical history between patients with and without HBV reactivation. Among 765 patients with resolved HBV infection, HBV reactivation occurred in 1 (0.1%) patient after initial resolution, whose HBV DNA level spontaneously decreased after DAA therapy. We compared anti-HBs titres at baseline with those at post-DAA therapy in 123 patients without HBsAg. There was no significant difference in anti-HBs levels between the two points (P = .79). In conclusion, HBV reactivation was rare in HBsAg-negative patients treated with DAA therapy. Additionally, hepatitis did not occur in HBV-reactivated patients with a baseline HBV DNA level <2000 IU/mL before DAA therapy.

Employing a cobalt-bisoxazoline catalyst, various alpha-arylalkanoic esters were synthesized in excellent enantioselectivities and yields (up to 97 % ee and 98 % yield). A diverse range of functional groups, including ether, halide, thioether, silyl, amine, ester, acetal, amide, olefin and heteroaromatics is tolerated by this method. This method was suitable for gram-scale reactions, enabling the synthesis of (R)-xanthorrhizol with high enantiopurity. Radical clock experiments support the intermediacy of radicals.

AB - Timothy syndrome (TS) is a multisystemic disease that occurs because of a mutation in CACN1C gene and is characterized by prolonged QT interval. Mexiletine is a Class 1B antiarrhythmic drug that causes the disappearance of T-wave alternans by shortening QTc and peak-to-end of the T wave. It may block the development of torsades de pointes in a prolonged QT. This study presented the case of a patient diagnosed with TS and had a cardiac arrest history, prolonged QT, and T-wave alternans. After mexiletine treatment, the QTc interval shortened and T-wave alternans disappeared. Such a case has rarely been seen in the literature, and hence considered rare. This case presentation was of particular importance because it highlighted the use of mexiletine besides an initial beta blocker treatment in the cases with TS. PMID- 29194861 TI - Trends in hepatocellular carcinoma incidence and survival among people with hepatitis C: An international study. AB - This study evaluates trends in hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) incidence and survival in three settings, prior to introduction of direct-acting antiviral (DAA) therapies. HCV notifications from British Columbia (BC), Canada; New South Wales (NSW), Australia; and Scotland (1995 2011/2012/2013, respectively) were linked to HCC diagnosis data via hospital admissions (2001-2012/2013/2014, respectively) and mortality (1995 2013/2014/2015, respectively). Age-standardized HCC incidence rates were evaluated, associated factors were assessed using Cox regression, and median survival time after HCC diagnosis was calculated. Among 58 487, 84 529 and 31 924 people with HCV in BC, NSW and Scotland, 734 (1.3%), 1045 (1.2%) and 345 (1.1%) had an HCC diagnosis. Since mid-2000s, HCC diagnosis numbers increased in all jurisdictions. Age-standardized HCC incidence rates remained stable in BC and Scotland and increased in NSW. The strongest predictor of HCC diagnosis was older age [birth <1945, aHR in BC 5.74, 95% CI 4.84, 6.82; NSW 9.26, 95% CI 7.93, 10.82; Scotland 12.55, 95% CI 9.19, 17.15]. Median survival after HCC diagnosis remained stable in BC (0.8 years in 2001-2006 and 2007-2011) and NSW (0.9 years in 2001-2006 and 2007-2013) and improved in Scotland (0.7 years in 2001-2006 to 1.5 years in 2007-2014). Across the settings, HCC burden increased, individual level risk of HCC remained stable or increased, and HCC survival remained extremely low. These findings highlight the minimal impact of HCC prevention and management strategies during the interferon-based HCV treatment era and form the basis for evaluating the impact of DAA therapy in the coming years.

AB - In many species, males may exhibit alternative life histories to circumvent the costs of intrasexual competition and female courtship. While the evolution and underlying genetic and physiological mechanisms behind alternative reproductive tactics are well studied, there has been less consideration of the ecological factors that regulate their prevalence. Here, we examine six decades of age composition records from thirty-six populations of sockeye salmon (Oncorhynchus nerka) to quantify associations between spawning habitat characteristics and the prevalence of precocious sneakers known as 'jacks'. Jack prevalence was independent of neutral genetic structure among stream populations, but varied among habitat types and as a function of continuous geomorphic characteristics. Jacks were more common in streams relative to beaches and rivers, and their prevalence was negatively associated with stream width, depth, elevation, slope and area, but positively related to bank cover. Behavioural observations showed that jacks made greater use of banks, wood and shallows than guard males, indicating that their reproductive success depends on the availability of such refuges. Our results emphasize the role of the physical habitat in shaping reproductive tactic frequencies among populations, likely through local adaptation in response to variable fitness expectations under different geomorphic conditions. PMID- 29194864 TI - Comparison of outpatient and home-based exercise training programmes for COPD: A systematic review and meta-analysis. AB - Chronic obstructive pulmonary disease is a common, preventable and treatable disease. Exercise training programmes (ETPs) improve symptoms, health-related quality of life (HRQoL) and exercise capacity, but the optimal setting is unknown. In this review, we compared the effects of ETPs in different settings on HRQoL and exercise capacity. We searched (5 July 2016) the Cochrane Airways Group Specialised Register, ClinicalTrials.gov and World Health Organization trials portal. We selected studies, extracted data and assessed risk of bias with two independent reviewers. We calculated mean differences (MD) with 95% CI. We assessed the quality of evidence using Grades of Recommendation, Assessment, Development and Evaluation. Ten trials (934 participants) were included. Hospital (outpatient) and home-based ETPs (seven trials) were equally effective at improving HRQoL on the Chronic Respiratory Questionnaire (CRQ) (dyspnoea: MD 0.09, 95% CI: -0.28 to 0.10; fatigue: MD -0.00, 95% CI: -0.18 to 0.17; emotional: MD 0.10, 95% CI: -0.24 to 0.45; and mastery: MD -0.02, 95% CI: -0.28 to 0.25; moderate quality) and on the St George's Respiratory Questionnaire (SGRQ) (MD 0.82, 95% CI: -7.47 to 5.83, low quality). Hospital (outpatient) and community based ETPs (three trials) were equally effective at improving HRQoL (CRQ dyspnoea: MD 0.29, 95% CI: -0.05 to 0.62, moderate quality; fatigue: MD -0.02, 95% CI: -1.09 to 1.05, low quality; emotional: MD 0.10, 95% CI: -0.40 to 0.59, moderate quality; and mastery: MD -0.08, 95% CI: -0.45 to 0.28, moderate quality). There was no difference in exercise capacity. There was low to moderate evidence that outpatient and home-based ETPs are equally effective. See related Editorial.

AB - OBJECTIVES: Urinary tract infection, urinary frequency, urgency, urodynia and haemorrhage are common post-operative complications of thulium laser resection of the prostate (TmLRP). Our study mainly focuses on the role of finasteride in prostate wound healing through AR signalling. MATERIALS AND METHODS: TmLRP beagles were randomly distributed into different treatment groups. Serum and intra-prostatic testosterone and DHT level were determined. Histological analysis was conducted to study the re-epithelialization and inflammatory response of the prostatic urethra in each group. We investigated the role of androgen in proliferation and inflammatory response in prostate. In addition, the effects of TNF-alpha on prostate epithelium and stromal cells were also investigated. RESULTS: Testosterone and DHT level increased in testosterone group and DHT decreased in finasteride group. Accelerated wound healing of prostatic urethra was observed in the finasteride group. DHT suppressed proliferation of prostate epithelium and enhanced inflammatory response in prostate. We confirmed that DHT enhanced macrophages TNF-alpha secretion through AR signalling. TNF-alpha suppressed proliferation of prostate epithelial cells and retarded cell migration. TNF-alpha also played a pivotal role in suppressing fibroblasts activation and contraction. CONCLUSION: Testosterone treatment repressed re epithelialization and wound healing of prostatic urethra. Finasteride treatment may be an effective way to promote prostate re-epithelialization. PMID- 29194866 TI - Break-through bleeding in relation to pharmacokinetics of Factor VIII in paediatric patients with severe haemophilia A. AB - INTRODUCTION: As the pharmacokinetics (PK) of factor VIII (FVIII) is individualized in children with haemophilia A (HA), PK parameters may be indicators of patients' bleeding phenotype and instruction for their personalized replacement program. AIM: The aim of this study was to investigate the possible relationship between PK/FVIII level and bleeding frequency in Chinese paediatric patients with severe (HA). METHODS: A total of 24 patients were enrolled in Beijing Children's Hospital from February to October 2015, all of whom were given 50 IU/kg of FVIII concentrates after a 72-hours washout period. Samples' activities (FVIII:C) were tested at 5 time points, using WinNonlin software for PK testing, and then the individual half-life(t1/2 ) and the time (h) of FVIII concentrations <1 IU/dL within a week during prophylaxis were calculated. Baseline and the annual bleeding rate (ABR), annual joint bleeding rate (AJBR) were recorded and analyzed. RESULTS: The mean t1/2 of FVIII was 10.20 +/- 2.72 hours and the mean time of FVIII <1 IU/dL in 1 week was 44.7 hours (-38.56 to 102.33 hours). A significant relationship between t1/2 of FVIII and ABR0 /AJBR0 (baseline bleeding) was found (R2 = 0.75 and 0.62, P < .001). Besides, baseline and the annual bleeding rate during prophylactic treatment of haemophilia had a positive correlation with the time (hours) of FVIII <1 IU/dL in 1 week (R2 = 0.67 and 0.52, P < .001). CONCLUSION: t1/2 was an important indicator to prevent bleeding in severe HA; the frequency of bleeding will be reduced with the increased of t1/2 of FVIII. The data also demonstrates that increasing the time with a FVIII<1 IU/dL is associated with an increased rate of bleeding during prophylaxis. PMID- 29194867 TI - Relationship between Hammett's parameters and in silico density functional with tandem mass ESI-CID fragmentation: Dihydropyridines as prototypes. AB - Over the years, with the instrumental analysis evolution, the relationships between the carried-out results with the data of theoretical analysis in silico and the Hammett's parameters have been reported. They have been very useful for chemical characterization of small organic molecules. Thus, this work aims at showing the feasibility and limitations for Hammett's and density functional theory applications in electrospray ionization-collision-induced dissociation (ESI-CID) fragmentation provision. For this, 13 dihydropyrimidinones para, meta, and orto monosubstituted were studied using ESI and CID in positive mode. As a result, it was observed that the main fragmentation includes the isocyanate and ethanol loses at low energy. Nevertheless, at higher energies, radical ions formed by McLafferty rearrangement were observed. The Hammett plots were correlated fragmentation profiles, showing good linearity for the [M + H]+ , which does not occur to radical ions and carbocation's. These tendencies had demonstrated that the stability of protonate and activation energy of secondary ions changes with the pKa. The density functional theory studies indicated that, both nitrogen atoms in the dihydropyrimidinone's prototypes are capable of being protonated. However, the activation energy of fragmentation products is not changed. Therefore, this work has shown information, which can be useful to understand tandem mass spectrometry in ESI-CID conditions for small organic molecules series. This is the first step for normalization of fragmentation pathway. PMID- 29194868 TI - Narrowing filtered QRS duration on signal-averaged electrocardiogram predicts outcomes in cardiac resynchronization therapy patients with nonischemic heart failure. AB - BACKGROUND: To evaluate the impact of changes in the filtered QRS duration (fQRS) on signal-averaged electrocardiograms (SAECGs) from pre- to postimplantation on the clinical outcomes in nonischemic heart failure (HF) patients under cardiac resynchronization therapy (CRT). METHODS: We studied 103 patients with nonischemic HF and sinus rhythm who underwent CRT implantation. SAECGs were obtained within 1 week before and 1 week after implantation and narrowing fQRS was defined as a decrease in fQRS from pre- to postimplantation. Echocardiography was performed before and 6 months after CRT implantation. The primary outcome was death from any cause. The secondary outcomes were hospitalization due to worsened HF and occurrence of ventricular tachyarrhythmias. RESULTS: Of the 103 CRT patients, 53 (51%) showed narrowing fQRS. Left ventricular end-diastolic volume and end-systolic volume were significantly reduced (both p < .001), and the left ventricular ejection fraction was significantly increased (p < .001) after CRT in patients with narrowing fQRS, but not in patients with nonnarrowing fQRS. During a median follow-up period of 33 months, patients with narrowing fQRS exhibited better survival than patients with nonnarrowing fQRS (p = .007). A lower incidence of hospitalization due to worsened HF (p < .001) and a lower occurrence of ventricular tachyarrhythmias (p = .071) were obtained in patients with narrowing fQRS. After adjusting for confounding variables, narrowing fQRS was associated with a low risk of mortality (HR 0.27, p = .006). CONCLUSION: Our results suggested that narrowing fQRS on SAECG after CRT implantation predicts LV reverse remodeling and long-term outcomes in nonischemic HF patients. PMID- 29194869 TI - Muscle strength and motor function throughout life in a cross-sectional cohort of 180 patients with spinal muscular atrophy types 1c-4. AB - BACKGROUND AND PURPOSE: Natural history studies in spinal muscular atrophy (SMA) have primarily focused on infants and children. Natural history studies encompassing all age groups and SMA types are important for the interpretation of treatment effects of recently introduced survival motor neuron gene-augmenting therapies. METHODS: We conducted a cross-sectional study to investigate muscle strength, Hammersmith Functional Motor Scale (Expanded) score and the patterns of muscle weakness in relation to age and SMA type. RESULTS: We included 180 patients with SMA types 1-4 in the age range 1-77.5 years with median disease duration of 18 (range 0-65.8) years. With the exception of the early phases of disease in which children with SMA types 2 and 3 may achieve new motor skills and show a temporary increase in muscle strength, cross-sectional data suggested that declining muscle strength and loss of motor skills over time are characteristic of all SMA types. Mean loss of strength was at least 1 point on the Medical Research Council score and 0.5 point on the Hammersmith Functional Motor Scale (Expanded) score per year. Trend lines compatible with deterioration of motor function and muscle strength started in childhood and continued into adulthood. The age at loss of specific motor skills was associated with disease severity. Triceps, deltoid, iliopsoas and quadriceps were the weakest muscles in all patients. Hierarchical cluster analysis did not show a segmental distribution of muscle weakness as suggested previously. CONCLUSIONS: Progressive muscle weakness and loss of motor function are characteristic of all SMA types and all ages.

AB - The treatment option in chronic hepatitis B (CHB) patients with persistent low level viremia despite entecavir or tenofovir monotherapy is unclear. This study investigated the development of hepatocellular carcinoma (HCC) or cirrhosis in hepatitis B e antigen (HBeAg)-positive high viral load CHB patients, according to the time needed to achieve complete viral suppression. A total of 325 HBeAg positive CHB patients with high viral load who were recently started on antiviral therapy with entecavir or tenofovir were included. The enrolled patients were divided into 2 groups with 4 separate criteria based on the time needed to achieve complete viral suppression: within 1, 2, 3 or 4 years of therapy initiation. The outcomes were development of HCC and cirrhosis. The cumulative incidence of HCC was significantly higher in patients failing complete viral suppression within 1 year (hazard ratio (HR), 4.54; 95% confidence interval (CI), 1.03-19.93; P = .045) or 2 years (HR, 3.38; 95% CI, 1.24-9.23; P = .018), than patients who achieved complete viral suppression within 1 or 2 years, respectively. Cumulative incidence of cirrhosis was also significantly higher in patients failing suppression within 1 year (HR, 1.95; 95% CI, 1.04-3.66; P = .037) or 2 years (HR, 2.44; 95% CI, 1.41-4.22; P = .001). When the time for achieving viral suppression exceeded 2 years, the cumulative incidence of HCC or cirrhosis was not different regardless of viral suppression. Complete hepatitis B virus suppression within 2 years of antiviral therapy initiation is associated with risk reduction in HCC or cirrhosis development. PMID- 29194871 TI - Are you better? A multi-centre study of patient-defined recovery from Complex Regional Pain Syndrome. AB - BACKGROUND: Complex Regional Pain Syndrome (CRPS) symptoms can significantly differ between patients, fluctuate over time, disappear or persist. This leads to problems in defining recovery and in evaluating the efficacy of therapeutic interventions. OBJECTIVES: To define recovery from the patients' perspective and better understand their priorities for treatment approaches. METHODS: Establishing an international consortium, we used a 2-Round Delphi-based study in eight countries across Europe and North America. Participants >=18 years who met, or had met, Budapest clinical criteria were included. Round 1 participants completed the statement: 'I would/do consider myself recovered from CRPS if/because...' alongside demographic and health questionnaires. Data were thematically organised and represented as 62 statements, from which participants identified and ranked their recovery priorities in Round 2. RESULTS: Round 1 (N = 347, 80% female, 91% non-recovered) dominant ICF themes were: activities of daily living; bodily functions; external factors; participation and personal factors. The top five priority statements in Round 2 (N = 252) were: no longer having (1) CRPS-related pain, (2) generalised pain and discomfort, (3) restricted range of movement, (4) need for medication, (5) stiffness in the affected limb. With very few exceptions, priorities were consistent, irrespective of patient demographics/geography. Symptoms affecting daily activities were among those most frequently reported. CONCLUSIONS: Our data showed a small number of themes are of highest importance to CRPS patients' definition of recovery. Patients want their pain, movement restriction and reliance on medication to be addressed, above all other factors. These factors should therefore be foremost concerns for future treatment and rehabilitation programmes. SIGNIFICANCE: Those with longstanding CRPS may no longer meet diagnostic criteria but still be symptomatic. Defining recovery is therefore problematic in CRPS. Our study has identified patients' definition of recovery from CRPS, in order of priority, as relief from: their CRPS-related pain, generalised pain, movement restriction, reliance on medication, and stiffness.

AB - The aim of the present study was to find out if in children ablation of 50% of renal mass may be associated with a progressive renal damage (Brenner's hypothesis). We collected 1035 adult or adolescent survivors who underwent nephrectomy for unilateral oncological or non-oncological causes during childhood. Stratification of all survivors for age revealed that the number of subjects with blood hypertension and/or renal dysfunction (glomerular filtration rate < 90 mL/min per 1.73 m2 ) to be significantly higher in survivors >=30 years old in comparison with younger patients. Available data on long-term renal function after nephrectomy during childhood support the Brenner's hypothesis. PMID- 29194873 TI - Stable NCNgNSi (Ng=Kr, Xe, Rn) Compounds with Covalently Bound C-Ng-N Unit: Possible Isomerization of NCNSi through the Release of the Noble Gas Atom. AB - Although the noble gas (Ng) compounds with either Ng-C or Ng-N bonds have been reported in the literature, compounds containing both bonds are not known. The first set of systems having a C-Ng-N bonding unit is predicted herein through the analysis of stability and bonding in the NCNgNSi (Ng=Kr-Rn) family. While the Xe and Rn inserted analogues are thermochemically stable with respect to all dissociation channels, but for the one producing CNSiN and free Ng, NCKrNSi has another additional three-body dissociation channel, NCKrNSi->CN+Kr+NSi, which is exergonic by -9.8 kcal mol-1 at 298 K. This latter dissociation can be hindered by lowering the temperature. Moreover, the NCNgNSi->Ng+CNSiN dissociation is also kinetically prohibited by a quite high free energy barrier ranging from 25.2 to 39.3 kcal mol-1 , with a gradual increase in going from Kr to Rn. Therefore, these compounds are appropriate candidates for experimental realization. A detailed bonding analysis by employing natural bond orbital, electron density, energy decomposition, and adaptive natural density partitioning analyses indicates that both Ng-N and C-Ng bonds in the title compounds are covalent in nature. In fact, the latter analysis indicates the presence of delocalized 3c-3e sigma-bond within the C-Ng-N moiety and a totally delocalized 5c-2e sigma-bond in these compounds. This is an unprecedented bonding characteristic in the sense that the bonding pattern in Ng inserted compounds is generally represented as the presence of covalent bond in one side of Ng, and the ionic interaction in the other side. Further, the dissociation of Ng from NCNgNSi facilitates the formation of a higher energy isomer of NCNSi, CNSiN, which cannot be formed from bare NCNSi as such, because of the very high free energy barrier associated with the isomeric transformation. Therefore, in the presence of Ng atoms it might be possible to detect the high energy isomer. PMID- 29194874 TI - Late-onset severe long QT syndrome. AB - We report a case of torsades de pointes arrhythmia as the first manifestation of congenital Long QT syndrome in a 77-year-old man with family history of sudden unexplained death. This case illustrates the importance of vigilant clinical assessment and genetic counseling in families with sudden death in order to identify properly asymptomatic relatives at risk for cardiac events. It also demonstrates that Long QT syndrome can still manifest with potentially fatal arrhythmias late in life in previously asymptomatic elderly patients.

AB - The cyclic depsipeptide FR900359 (FR), isolated from the tropical plant Ardisia crenata, is a strong and selective inhibitor of Gq proteins, making it an indispensable pharmacological tool to study Gq-related processes, as well as a promising drug candidate. Gq inhibition is a novel mode of action for defense chemicals and crucial for the ecological function of FR, as shown by in vivo experiments in mice, its affinity to insect Gq proteins, and insect toxicity studies. The uncultured endosymbiont of A. crenata was sequenced, revealing the FR nonribosomal peptide synthetase (frs) gene cluster. We here provide a detailed model of FR biosynthesis, supported by in vitro enzymatic and bioinformatic studies, and the novel analogue AC-1, which demonstrates the flexibility of the FR starter condensation domains. Finally, expression of the frs genes in E. coli led to heterologous FR production in a cultivable, bacterial host for the first time.

AB - In spite of substantial spending and resource utilization, today's health care remains characterized by poor outcomes, largely due to overuse (overtesting/overtreatment) or underuse (undertesting/undertreatment) of health services. To a significant extent, this is a consequence of low-quality decision making that appears to violate various rationality criteria. Such suboptimal decision making is considered a leading cause of death and is responsible for more than 80% of health expenses. In this paper, we address the issue of overuse or underuse of health care interventions from the perspective of rational choice theory. We show that what is considered rational under one decision theory may not be considered rational under a different theory. We posit that the questions and concerns regarding both underuse and overuse have to be addressed within a specific theoretical framework. The applicable rationality criterion, and thus the "appropriateness" of health care delivery choices, depends on theory selection that is appropriate to specific clinical situations. We provide a number of illustrations showing how the choice of theoretical framework influences both our policy and individual decision making. We also highlight the practical implications of our analysis for the current efforts to measure the quality of care and link such measurements to the financing of health care services. PMID- 29194879 TI - Environmental heterogeneity and biotic interactions mediate climate impacts on tropical forest regeneration. AB - Predicting the fate of tropical forests under a changing climate requires understanding species responses to climatic variability and extremes. Seedlings may be particularly vulnerable to climatic stress given low stored resources and undeveloped roots; they also portend the potential effects of climate change on future forest composition. Here we use data for ca. 50,000 tropical seedlings representing 25 woody species to assess (i) the effects of interannual variation in rainfall and solar radiation between 2007 and 2016 on seedling survival over 9 years in a subtropical forest; and (ii) how spatial heterogeneity in three environmental factors-soil moisture, understory light, and conspecific neighborhood density-modulate these responses. Community-wide seedling survival was not sensitive to interannual rainfall variability but interspecific variation in these responses was large, overwhelming the average community response. In contrast, community-wide responses to solar radiation were predominantly positive. Spatial heterogeneity in soil moisture and conspecific density were the predominant and most consistent drivers of seedling survival, with the majority of species exhibiting greater survival at low conspecific densities and positive or nonlinear responses to soil moisture. This environmental heterogeneity modulated impacts of rainfall and solar radiation. Negative conspecific effects were amplified during rainy years and at dry sites, whereas the positive effects of radiation on survival were more pronounced for seedlings existing at high understory light levels. These results demonstrate that environmental heterogeneity is not only the main driver of seedling survival in this forest but also plays a central role in buffering or exacerbating impacts of climate fluctuations on forest regeneration. Since seedlings represent a key bottleneck in the demographic cycle of trees, efforts to predict the long-term effects of a changing climate on tropical forests must take into account this environmental heterogeneity and how its effects on regeneration dynamics play out in long-term stand dynamics.

AB - To determine the knowledge regarding hepatitis B virus (HBV) mother-to-child transmission (MTCT) and its prevention and treatment among healthcare workers (HCWs) in Guangdong Province, China, an HBV endemic area. An HBV knowledge questionnaire was administered to 900 HCWs from the 3rd Affiliated Hospital of Sun Yat-Sen University and 2 rural hospitals in Guangdong Province. The 27 items in the questionnaire fell into 3 sections: HBV MTCT general knowledge, respondents' practices of preventing HBV MTCT and awareness of the resources of preventing HBV MTCT. The data collected were coded and analysed using SPSS software version 20. In total, 503 of 900 HCWs responded to the survey (response rate: 55.9%). Eighty-four individuals responded correctly to all of the knowledge questions: 58 were doctors, and 26 were nurses (P < .05). Doctors more often performed practices than nurses (t = 3.591, P < .01). Participants from the infectious disease department demonstrated a significantly higher proportion of correct answers and resource utilization than other specialties (chi2 = 14.052, 7.998, P < .01). In terms of the average knowledge score, t test or ANOVA showed that there were significant differences between the specialty groups (t = 3.110, P < .01), hospital level groups (t = 2.337, P < .05) and age groups (F = 3.020, P < .05). Respondents' initiative increased with hospital level and age (t = 2.993, 7.493, P < .01). A considerable percentage of HCWs has misconceptions about HBV MTCT. Healthcare workers, in particular nurses, those working in noninfectious disease departments or township hospitals and younger medical staff, lack systematic and comprehensive knowledge about HBV MTCT and are in urgent need of HBV-related training. PMID- 29194880 TI - Zika virus dynamics in body fluids and risk of sexual transmission in a non endemic area. AB - OBJECTIVE: To understand Zika virus (ZIKV) dynamics in fluids of infected individuals and the risk of sexual transmission. METHODS: Prospective study at two centres in Spain. Patients with probable or confirmed diagnosis of ZIKV infection were clinically followed up, and fluid samples were collected from saliva, serum, urine and semen or vaginal secretion following the study protocol. Non-traveller-sexual partners were offered to participate. RESULTS: From January 2016 to December 2016, we included a total of 11 traveller patients and six sexual contacts. Six patients were male, with a median age of 38 years (IQR 30 45). We performed 61 RT-PCR determinations, seven of which were positive. Positive results were retrieved from serum, urine, semen and vaginal tract. One of four women tested positive for ZIKV RNA in vaginal swabs collected during the first 45 days after symptoms onset. Clearance occurred between day 37 and day 69 after symptoms onset. One of five men tested positive for ZIKV RNA in semen collected during the first 45 days after symptoms onset. Clearance occurred between day 23 and 107 after symptoms onset. Six patients had sexual relations during the defined period. All tested patients were negative for ZIKV infection by serological testing. CONCLUSION: ZIKV shedding persistence in genital fluids occurs in a significant number of symptomatic patients after visiting an endemic area. We did not find any ZIKV seroconversion among the three male contacts who were investigated. Diagnostic algorithms may be updated to include genital tract fluid specimens in the diagnostic process.

The study highlights a peculiar geometric preference for the Z dienoate to furnish the cycloadduct. The endgame involves a reaction cascade, including lactone opening, alcohol oxidation, and ketone epimerization to complete an efficient synthesis. A salient feature of the synthesis is the resulting reassignment of the absolute configuration, which corrects the previously reported nominal structure.

Compared to its oxygen counterpart, the sulfur atom displays a remarkable ability to interact with almost equal facility over the entire range of pi systems studied, with the simple alkene emerging as the most powerful partner. With the exception of the O???heteroarene interaction, all noncovalent interactions of sulfur with pi systems are favoured over oxygen.

Inpatient units are the most widely used acute element of adolescent mental health services internationally. Little is known about inpatient units, particularly when it comes to measuring improvement for adolescents. Clinical outcome measurement in the broad context has gathered momentum in recent years, driven by the need to assess services. The measurement of outcomes for adolescents who access inpatient care is critical, as they are particularly vulnerable and are often considered the most difficult to treat. Following the PRISMA guidelines, the aim of this review was to assess whether adolescent inpatient units are effective and understand how outcomes are measured. CINAHL, MEDLINE with Full Text, ERIC, PsycINFO, and Cochrane databases were systematically searched. Studies were included if the inpatient units were generic and adolescents were between the mean age of 12-25 years. Furthermore, studies published in English within the last ten years were included. Exclusions were outpatient and disorder-specific inpatient settings. A total of 16 studies were identified. Each study demonstrated effectiveness on at least one outcome measure in terms of symptom stabilization. However, several outcome measures were used and therefore inpatient units lack consistency in how they measure improvement. Inpatient units are effective for the majority of young people as they result in symptom stabilization. Whilst symptom stabilization can be achieved, future research examining the mechanism of change is needed.

AB - The positive region that lies above the plane of F2 TO (T=C and Si) interacts with malondialdehyde (MDA), which contains an intramolecular H-bond. The T atom of F2 TO can lie either in the MDA molecular plane, forming a T???O tetrel bond, or F2 TO can stack directly above MDA in a parallel arrangement. The former structure is more stable than the latter, and in either case, F2 SiO engages in a much stronger interaction than does F2 CO, reaching nearly 200 kJ mol-1 . The pi tetrel bond strengthens/weakens the MDA H-bond when the bond is formed to the hydroxyl/carbonyl group of MDA, and causes an accompanying inhibition/promotion of proton transfer within this H-bond; this effect is stronger for F2 SiO. These same aspects can be tuned by substituents placed on any of the C atoms of MDA, although their effects are not fully correlated with the electron-withdrawing or electron-releasing properties of the substituent. A new type of pi-pi tetrel bond occurs when the pi-hole on the T atom of F2 TO approaches the middle carbon atom of MDA from above, and a similar configuration is also found between F2 TO and benzene. Evidence for extensive C???C pi-pi tetrel bonding in crystal materials is presented.

AB - Sesterterpenoids are a relatively rare class of plant terpenes. Sesterterpene synthase (STS)-mediated cyclization of the linear C25 isoprenoid precursor geranylfarnesyl diphosphate (GFPP) defines sesterterpene scaffolds. So far only a very limited number of STSs have been characterized. The discovery of three new plant STSs is reported that produce a suite of sesterterpenes with unprecedented 6/11/5 and 6/6/7/5 fused ring systems when transiently co-expressed with a GFPP synthase in Nicotiana benthamiana. Structural elucidation, feeding experiments, and quantum chemical calculations suggest that these STSs catalyze an unusual cyclization path involving reprotonation, intramolecular 1,6 proton transfer, and concerted but asynchronous bicyclization events. The cyclization is diverted from those catalyzed by the characterized plant STSs by forming unified 15/5 bicyclic sesterterpene intermediates. Mutagenesis further revealed a conserved amino acid residue implicated in reprotonation.

AB - An electron-donor-acceptor-acceptor (D-A1 -A2 ) triad has been developed that provides the first proof-of-concept for a photoinitiated molecular circuit. After photoexcitation into an optical charge-transfer transition between D and A1 , subsequent thermal electron-transfer from A1.- to A2 is followed by geometric rearrangement in the D.+ -A1 -A2.- charge-separated state to form an ion-pair contact. This facilitates "forward" charge recombination between A2.- and D.+ to complete the molecular circuit with an estimated quantum efficiency of 4 % in toluene at 298 K.

AB - We report the synthesis, characterization, and photo-physical properties of two new rutheniumII -phenol-imidazole complexes. These bio-mimetic complexes have potential as photocatalysts for water splitting. Owing to their multiple phenol imidazole groups, they have a higher probability of light-induced radical formation than existing complexes. The newly synthesized complexes show improved overlap with the solar spectrum compared to other rutheniumII -phenol-imidazole complexes, and their measured lifetimes are suitable for light-induced radical formation. In addition, we conducted solvatochromic absorption measurements, which elegantly follow Marcus theory, and demonstrate the symmetry differences between the two complexes. The solvatochromic measurements further imply electron localization onto one of the ligands. The new complexes may find applications in photocatalysis, dye-sensitized solar cells, biomedicine, and sensing. Moreover, their multiple chelating units make them promising candidates for light-activated metal organic radical frameworks, i.e. metal-organic frameworks that contain organic radicals activated by light. PMID- 29194897 TI - A Six-Oxidase Cascade for Tandem C-H Bond Activation Revealed by Reconstitution of Bicyclomycin Biosynthesis. AB - As a commercial antibiotic, bicyclomycin (BCM) is currently the only known natural product targeting the transcription termination factor rho. It belongs to a family of highly functionalized diketopiperazine (DKP) alkaloids and bears a unique O-bridged bicyclo[4.2.2]piperazinedione ring system, a C1 triol, and terminal exo-methylene groups. We have identified and characterized the BCM biosynthetic pathway by heterologous biotransformations, in vitro biochemical assays, and one-pot enzymatic synthesis. A tRNA-dependent cyclodipeptide synthase guides the heterodimerization of leucine and isoleucine to afford the DKP precursor; subsequently, six redox enzymes, including five alpha ketoglutarate/Fe2+ -dependent dioxygenases and one cytochrome P450 monooxygenase, regio- and stereoselectively install four hydroxy groups (primary, secondary, and two tertiary), an exo-methylene moiety, and a medium-sized bridged ring through the functionalization of eight unactivated C-H bonds. PMID- 29194898 TI - Perioperative albumin ratio is associated with post-operative pancreatic fistula. AB - BACKGROUND: Despite improvements in surgical techniques and perioperative management, post-operative pancreatic fistula (POPF) remains a serious complication after pancreaticoduodenectomy (PD). The aim of this study was to evaluate the role of perioperative clinical variables of patients, including albumin level, in predicting pancreatic fistula. METHODS: A total of 86 patients underwent PD for pancreas cancer between 2011 and 2017 at our institution. We prospectively investigated the relation between patient's characteristics and the incidence of clinically relevant (CR)-POPF. Perioperative albumin ratio was defined as post-operative day 1 (POD1) albumin level/preoperative albumin level. RESULTS: A total of 23 patients (26.7%) developed CR-POPF. At univariate analysis POPF correlated with soft pancreas (P = 0.045), low POD1 albumin (P = 0.02), POD1 and POD3 amylase levels in drainage fluid (P = 0.003 and P = 0.014, respectively) and perioperative albumin ratio (0.58 +/- 0.10 versus 0.69 +/- 0.12 in patients without POPF; P = 0.003). No significant correlations with POPF were demonstrated for surgical time, serum amylase levels and preoperative albumin levels. At multivariate analysis POD3 amylase level in drainage fluid and perioperative albumin ratio were the only significant independent parameters (P = 0.027 and P = 0.047, respectively). CONCLUSIONS: Perioperative albumin ratio can predict POPF after PD. PMID- 29194900 TI - Jejunogastric intussusception: shall we think about it?

AB - INTRODUCTION AND OBJECTIVE: The ODHIN trial found that training and support and financial reimbursement increased the proportion of patients that were screened and given advice for their heavy drinking in primary health care. However, the impact of these strategies on professional accuracy in delivering screening and brief advice is underresearched and is the focus of this paper. METHOD: From 120 primary health care units (24 in each jurisdiction: Catalonia, England, the Netherlands, Poland, and Sweden), 746 providers participated in the baseline and the 12-week implementation periods. Accuracy was measured in 2 ways: correctness in completing and scoring the screening instrument, AUDIT-C; the proportion of screen-negative patients given advice, and the proportion of screen-positive patients not given advice. Odds ratios of accuracy were calculated for type of profession and for intervention group: training and support, financial reimbursement, and internet-based counselling. RESULTS: Thirty-two of 36 711 questionnaires were incorrectly completed, and 65 of 29 641 screen-negative patients were falsely classified. At baseline, 27% of screen-negative patients were given advice, and 22.5% screen-positive patients were not given advice. These proportions halved during the 12-week implementation period, unaffected by training. Financial reimbursement reduced the proportion of screen-positive patients not given advice (OR = 0.56; 95% CI, 0.31-0.99; P < .05). CONCLUSION: Although the use of AUDIT-C as a screening tool was accurate, a considerable proportion of risky drinkers did not receive advice, which was reduced with financial incentives. PMID- 29194901 TI - Photobiocatalysis: Activating Redox Enzymes by Direct or Indirect Transfer of Photoinduced Electrons. AB - Biocatalytic transformation has received increasing attention in the green synthesis of chemicals because of the diversity of enzymes, their high catalytic activities and specificities, and mild reaction conditions. The idea of solar energy utilization in chemical synthesis through the combination of photocatalysis and biocatalysis provides an opportunity to make the "green" process greener. Oxidoreductases catalyze redox transformation of substrates by exchanging electrons at the enzyme's active site, often with the aid of electron mediator(s) as a counterpart. Recent progress indicates that photoinduced electron transfer using organic (or inorganic) photosensitizers can activate a wide spectrum of redox enzymes to catalyze fuel-forming reactions (e.g., H2 evolution, CO2 reduction) and synthetically useful reductions (e.g., asymmetric reduction, oxygenation, hydroxylation, epoxidation, Baeyer-Villiger oxidation). This Review provides an overview of recent advances in light-driven activation of redox enzymes through direct or indirect transfer of photoinduced electrons. PMID- 29194902 TI - Metastatic prostate cancer incidence in Australia after amendment to prostate specific antigen screening guidelines. AB - BACKGROUND: To compare the incidence of newly diagnosed metastatic prostate cancer at an Australian facility pre- and post-publication of the United States Preventive Services Task Force (USPSTF) guidelines and subsequent amendment of the Royal Australian College of General Practitioners Preventive Activities in General Practice guidelines. METHODS: A retrospective analysis was undertaken by patients with newly diagnosed prostate cancer following transrectal ultrasound guided biopsy between 2009 and 2014. Patients were divided into two even groups based on whether they had undergone their transrectal ultrasound biopsy pre- (2009-2011) or post- (2013-2014) publication of USPSTF guidelines. Metastatic disease was determined by computed tomography chest, abdomen, pelvis as well as nuclear medicine bone scan. A comparison in the incidence of newly diagnosed metastatic prostate cancer was made. RESULTS: A total of 130 patients were allocated into each group. In the pre-USPSTF group, 23 out of 130 patients had newly diagnosed metastatic prostatic cancer (17.7%). In the post-USPSTF group, 41 out of 130 (31.5%) had newly diagnosed metastatic prostate cancer (P < 0.05). The mean and median prostate-specific antigen was 15.9 and 9.4 (pre-guideline group) and 33.0 and 9.8 (post-guideline group), respectively (P = 0.02). The post guidelines group had a higher incidence of low-grade disease (Gleason <7), a decreased incidence of intermediate grade disease (Gleason 7) and a relatively unchanged incidence in high-risk disease (Gleason >7). CONCLUSION: The incidence of newly diagnosed metastatic prostate cancer nearly doubled in patients referred to our Urology Department post-release of the USPSTF guidelines. PMID- 29194903 TI - The Hydrogen Evolution Reaction in Alkaline Solution: From Theory, Single Crystal Models, to Practical Electrocatalysts. AB - The hydrogen evolution reaction (HER) is a fundamental process in electrocatalysis and plays an important role in energy conversion for the development of hydrogen-based energy sources. However, the considerably slow rate of the HER in alkaline conditions has hindered advances in water splitting techniques for high-purity hydrogen production. Differing from well documented acidic HER, the mechanistic aspects of alkaline HER are yet to be settled. A critical appraisal of alkaline HER electrocatalysis is presented, with a special emphasis on the connection between fundamental surface electrochemistry on single crystal models and the derived molecular design principle for real-world electrocatalysts. By presenting some typical examples across theoretical calculations, surface characterization, and electrochemical experiments, we try to address some key ongoing debates to deliver a better understanding of alkaline HER at the atomic level. PMID- 29194904 TI - Investigating the Conformation of the Bridged Monosaccharide Levoglucosan. AB - Levoglucosan is one of the main products of the thermal degradation of glucose and cellulose and is commonly used as a tracer for biomass burning. Herein we report a conformational analysis of levoglucosan under isolation conditions, by means of microwave spectroscopy coupled with ultrafast laser vaporization in supersonic expansions. We observed three different conformations of levoglucosan in the gas phase. They all share a common heavy atom rigid bicyclic structure. The difference between the three of them lies in the network of intramolecular hydrogen bonds that arises from the OH groups at positions 2, 3 and 4. The different combinations of H-bonds give richness to the conformational landscape of levoglucosan. The gas phase conformers obtained in this work are compared to the crystal structure of levoglucosan previously reported. Although the heavy atom frame remains unchanged, there are significant differences in the positions of the H-atoms. In addition, the levoglucosan structure can be compared to the related glucose, for which gas phase conformational studies exist in the literature. In this case, in going from glucose to levoglucosan, there is an inversion in the chair conformation of the pyranose ring. This forces the OH groups to adopt axial positions (instead of the more favorable equatorial positions in glucose) and completely changes the pattern of intramolecular H bonds. PMID- 29194905 TI - Mental health nurses and mental health peer workers: Self-perceptions of role related clinical competences. AB - In a mental healthcare that embraces a recovery-oriented practice, the employment of mental health peer workers is encouraged. Although peer workers are increasingly working together with nurses, there is a lack of research that explores how nurses and peer workers perceive their role-related competences in clinical practice. The aim of this study was to clarify and understand these self perceptions in order to identify the specificity and potential complementarity of both roles. This insight is needed to underpin a successful partnership between both vocations. A qualitative descriptive research design based on principles of critical incident methodology was used. Twelve nurses and eight peer workers from different mental healthcare organizations participated. A total of 132 reported cases were analysed. Rigour was achieved through thick description, audit trail, investigator triangulation and peer review. Nurses relate their role-related competences predominantly with being compliant with instructions, being a team player and ensuring security and control. Peer workers relate their role-related competences with being able to maintain themselves as a peer worker, building up a relationship that is supportive for both the patient and themselves, and to utilize their lived experience. Both nurses and peer workers assign a major role to the team in determining their satisfaction with their competences. Consequently, what is perceived as important for the team appears to overshadow their self-assessment of competences. The findings highlighted the importance of paying more attention to identity construction, empowerment and role competence development of nurses and peer workers in their respective education and ongoing training. PMID- 29194906 TI - Radical gastric cancer surgery results in widespread upregulation of pro tumourigenic intraperitoneal cytokines. AB - BACKGROUND: Radical surgical resection is the mainstay of curative treatment for oesophagogastric malignancy. However, survival and recurrence rates remain poor. Theoretical data suggests that the inflammatory response to surgery can promote tumour recurrence. The local and systemic inflammatory response to radical oesophagogastric cancer surgery has not been fully characterized. We aimed to measure this response, particularly factors associated with tumour implantation. METHODS: Consecutive patients undergoing radical junctional or gastric cancer resection over 12 months were recruited. Repeated serum and adipose tissue were collected intra-operatively. Adipose tissue was collected adjacent and remote to the tumour, and cytokine messenger RNA (mRNA) expression was measured. Post operatively, daily serum was collected for 7 days, and analysed for inflammatory cell profile and cytokine concentration. RESULTS: There were nine patients recruited (67.1 +/- 2.1 years). mRNA expression of interleukin-6 (IL-6), CC chemokine ligand-2 and IL-1beta increased in adipose tissue intra-operatively (P < 0.05), equally both adjacent and remote from the tumour site. Serum IL-6 concentration increased from 23.3 pg/mL to 161.8 pg/mL intra-operatively (P < 0.05) before falling steadily to 35.7 pg/mL post-operatively (P < 0.05). Serum tumour necrosis factor-alpha was elevated throughout, and IL-1beta levels were unaffected. Leukocyte and neutrophil populations increased, while T-cell and dendritic cell populations decreased intra-operatively (P < 0.05). CONCLUSION: Radical surgery dramatically upregulates the expression of pro-tumourigenic cytokines in the peritoneum. There is also a marked systemic immune and inflammatory response to surgery, including downregulation of T-cell and dendritic cell populations. This offers two potential pathways that may facilitate tumour progression - local inflammation promoting peritoneal adherence and implantation, and secondary suppression of immunosurveillance due to circulating inflammatory response. PMID- 29194908 TI - Artificial beta-Double Helices from Achiral gamma-Peptides. AB - Double helices are not common in polypeptides and proteins except in the peptide antibiotic gramicidin A and analogous l,d-peptides. In contrast to natural polypeptides, remarkable beta-double-helical structures from achiral gamma peptides built from alpha,beta-unsaturated gamma-amino acids have been observed. The crystal structures suggest that they adopted parallel beta-double helical structures and these structures are stabilized by the interstrand backbone amide H-bonds. Furthermore, both NMR spectroscopy and fluorescence studies support the existence of double-helical conformations in solution. Although a variety of folded architectures featuring distinct H-bonds have been discovered from the beta- and gamma-peptide foldamers, this is the first report to show that achiral gamma-peptides can spontaneously intertwine into beta-double helical structures. PMID- 29194907 TI - 100 Days of marine Synechococcus-Ruegeria pomeroyi interaction: A detailed analysis of the exoproteome. AB - Marine phototroph and heterotroph interactions are vital in maintaining the nutrient balance in the oceans as essential nutrients need to be rapidly cycled before sinking to aphotic layers. The aim of this study was to highlight the molecular mechanisms that drive these interactions. For this, we generated a detailed exoproteomic time-course analysis of a 100-day co-culture between the model marine picocyanobacterium Synechococcus sp. WH7803 and the Roseobacter strain Ruegeria pomeroyi DSS-3, both in nutrient-enriched and natural oligotrophic seawater. The proteomic data showed a transition between the initial growth phase and stable-state phase that, in the case of the heterotroph, was caused by a switch in motility attributed to organic matter availability. The phototroph adapted to seawater oligotrophy by reducing its selective leakiness, increasing the acquisition of essential nutrients and secreting conserved proteins of unknown function. We also report a surprisingly high abundance of extracellular superoxide dismutase produced by Synechococcus and a dynamic secretion of potential hydrolytic enzyme candidates used by the heterotroph to cleave organic groups and hydrolase polymeric organic matter produced by the cyanobacterium. The time course dataset we present here will become a reference for understanding the molecular processes underpinning marine phototroph heterotroph interactions. PMID- 29194909 TI - Dominant forest tree mycorrhizal type mediates understory plant invasions. AB - Forest mycorrhizal type mediates nutrient dynamics, which in turn can influence forest community structure and processes. Using forest inventory data, we explored how dominant forest tree mycorrhizal type affects understory plant invasions with consideration of forest structure and soil properties. We found that arbuscular mycorrhizal (AM) dominant forests, which are characterised by thin forest floors and low soil C : N ratio, were invaded to a greater extent by non-native invasive species than ectomycorrhizal (ECM) dominant forests. Understory native species cover and richness had no strong associations with AM tree dominance. We also found no difference in the mycorrhizal type composition of understory invaders between AM and ECM dominant forests. Our results indicate that dominant forest tree mycorrhizal type is closely linked with understory invasions. The increased invader abundance in AM dominant forests can further facilitate nutrient cycling, leading to the alteration of ecosystem structure and functions. PMID- 29194910 TI - Moniliophthora roreri, causal agent of cacao frosty pod rot. AB - : Taxonomy: Moniliophthora roreri (Cif.) H.C. Evans et al. ; Phylum Basidiomycota; Class Agaricomycetes; Order Agaricales; Family Marasmiaceae; Genus Moniliophthora. Biology: Moniliophthora roreri attacks Theobroma and Herrania species causing frosty pod rot. Theobroma cacao (cacao) is the host of major economic concern. Moniliophthora roreri is a hemibiotroph with a long biotrophic phase (45-90 days). Spore masses, of apparent asexual origin, are produced on the pod surface after initiation of the necrotrophic phase. Spores are spread by wind, rain and human activity. Symptoms of the biotrophic phase can include necrotic flecks and, in some cases, pod malformation, but pods otherwise remain asymptomatic. Relationship to Moniliophthora perniciosa: Moniliophthora roreri and Moniliophthora perniciosa, causal agent of witches' broom disease of cacao, are closely related. Their genomes are similar, including many of the genes they carry which are considered to be important in the disease process. Moniliophthora perniciosa, also a hemibiotroph, has a typical basidiomycete lifestyle and morphology, forming clamp connections and producing mushrooms. Basidiospores infect meristematic tissues including flower cushions, stem tips and pods. Moniliophthora roreri does not form clamp connections or mushrooms and infects pods only. Both pathogens are limited to the Western Hemisphere and are a threat to cacao production around the world. Agronomic importance: Disease losses caused by frosty pod rot can reach 90% and result in field abandonment. Moniliophthora roreri remains in the invasive phase in the Western Hemisphere, not having reached Brazil, some islands within the Caribbean and a few specific regions within otherwise invaded countries. DISEASE MANAGEMENT: The disease can be managed by a combination of cultural (for example, maintenance of tree height and removal of infected pods) and chemical methods. These methods benefit from regional application, but can be cost prohibitive. Breeding for disease resistance offers the greatest potential for frosty pod rot management and new tolerant materials are becoming available. PMID- 29194911 TI - Solubility-Parameter-Guided Solvent Selection to Initiate Ostwald Ripening for Interior Space-Tunable Structures with Architecture-Dependent Electrochemical Performance. AB - Despite significant advancement in preparing various hollow structures by Ostwald ripening, one common problem is the intractable uncontrollability of initiating Ostwald ripening due to the complexity of the reaction processes. Here, a new strategy on Hansen solubility parameter (HSP)-guided solvent selection to initiate Ostwald ripening is proposed. Based on this comprehensive principle for solvent optimization, N,N-dimethylformamide (DMF) was screened out, achieving accurate synthesis of interior space-tunable MoSe2 spherical structures (solid, core-shell, yolk-shell and hollow spheres). The resultant MoSe2 structures exhibit architecture-dependent electrochemical performances towards hydrogen evolution reaction and sodium-ion batteries. This pre-solvent selection strategy can effectively provide researchers great possibility in efficiently synthesizing various hollow structures. This work paves a new pathway for deeply understanding Ostwald ripening. PMID- 29194912 TI - Sharing of prescription analgesics amongst patients in family practice: Frequency and associated factors. AB - OBJECTIVE: To analyse the frequency of nonrecreational prescription analgesic sharing, associated factors and differences between lenders and borrowers. METHODS: A cross-sectional study was conducted in 10 outpatient family medicine practices in Croatia amongst 1000 patients to whom their physicians have prescribed analgesics at least once in their lives. A questionnaire was used to collect data about patients' pain intensity, prescription analgesic sharing habits, factors associated with this behaviour, perception of risks associated with the conduct and demographic data. Logistic regression was conducted to analyse independent factors associated with lending and borrowing prescription analgesics. RESULTS: We found that 61% of patients in family medicine practices engage in sharing prescription analgesics, whether it was lending (42%) and/or borrowing (54%). Independent predictors of lending prescription analgesics were as follows: history of sharing prescription medication other than analgesics, providing information regarding the medication alongside the prescription medication itself, not reading package insert that accompanies medication, subjective perception of personal health and decreased awareness of personal harm associated with prescription analgesic sharing. Independent predictors of prescription analgesic borrowing were as follows: younger age, communicating details regarding the medication that was given, scanning of package insert accompanying the medication, biased subjective perception of personal health and perceiving alternative medicine as a safer option over conventional medicine. CONCLUSIONS: Sharing prescription analgesics is highly prevalent amongst patients in family medicine. Healthcare providers should remain alert by routinely questioning patients regarding such behaviours. Preventive interventions should be conceived and established. SIGNIFICANCE: Sharing of prescription analgesics is a highly prevalent behaviour amongst pain patients, and there exist independent factors associated with such conduct. This information can be useful in the design of interventions aimed at mitigating analgesic sharing behaviour in the future. PMID- 29194913 TI - Regulation of Nod factor biosynthesis by alternative NodD proteins at distinct stages of symbiosis provides additional compatibility scrutiny. AB - The Lotus japonicus symbiont Mesorhizobium loti R7A encodes two copies of nodD and here we identify striking differences in Nod factor biosynthesis gene induction by NodD1 and NodD2 both in vitro and in planta. We demonstrate that induction of Nod factor biosynthesis genes is preferentially controlled by NodD1 and NodD2 at specific stages of symbiotic infection. NodD2 is primarily responsible for induction in the rhizosphere and within nodules, while NodD1 is primarily responsible for induction within root hair infection threads. nodD1 and nodD2 mutants showed significant symbiotic phenotypes and competition studies establish that nodD1 and nodD2 mutants were severely outcompeted by wild-type R7A, indicating that both proteins are required for proficient symbiotic infection. These results suggest preferential activation of NodD1 and NodD2 by different inducing compounds produced at defined stages of symbiotic infection. We identified Lotus chalcone isomerase CHI4 as a root hair induced candidate involved in the biosynthesis of an inducer compound that may be preferentially recognized by NodD1 within root hair infection threads. We propose an alternative explanation for the function of multiple copies of nodD that provides the host plant with another level of compatibility scrutiny at the stage of infection thread development. PMID- 29194915 TI - Factors influencing lymph node skip metastasis in colorectal cancer: a retrospective study. AB - BACKGROUND: The risk factors for lymph node skip metastasis (LNSM) have not been thoroughly clarified in patients with advanced colorectal cancer (CRC). This study aimed to identify the risk factors for LNSM in CRC patients who underwent laparoscopic radical resection with D3 lymphadenectomy. METHODS: This retrospective cohort study included a total of 167 consecutive patients who underwent laparoscopic radical resection with D3 lymphadenectomy for CRC between April 2005 and June 2017. The patients were sorted into the LNSM-positive (skip+ group) and LNSM-negative (skip- group) groups. Logistic regression was used to identify the risk factors for LNSM. RESULTS: Compared with the skip- group, the frequency of tumour size <5 cm, pT1-2 stage, and pN1 stage were significantly higher in the skip+ group (tumour size <5 cm: 68.8 versus 46.7%, P = 0.025; pT1-2 stage: 18.8 versus 4.4%, P = 0.012; pN1 stage: 78.1 versus 57.0%, P = 0.028), respectively. Multivariate logistic regression analysis revealed that pT1-2 stage (odds ratio (OR) = 4.3, 95% confidence interval (CI): 1.1-16.6, P = 0.034) and pN1 stage (OR = 2.6, 95% CI: 1.1-6.8, P = 0.047) were independent risk factors for LNSM. CONCLUSIONS: pT1-2 stage and pN1 stage are significantly associated with LNSM. Radical D3 lymphadenectomy should remain standard practice for CRC. PMID- 29194914 TI - Cell-cell recognition and social networking in bacteria. AB - The ability to recognize self and to recognize partnering cells allows microorganisms to build social networks that perform functions beyond the capabilities of the individual. In bacteria, recognition typically involves genetic determinants that provide cell surface receptors or diffusible signalling chemicals to identify proximal cells at the molecular level that can participate in cooperative processes. Social networks also rely on discriminating mechanisms to exclude competing cells from joining and exploiting their groups. In addition to their appropriate genotypes, cell-cell recognition also requires compatible phenotypes, which vary according to environmental cues or exposures as well as stochastic processes that lead to heterogeneity and potential disharmony in the population. Understanding how bacteria identify their social partners and how they synchronize their behaviours to conduct multicellular functions is an expanding field of research. Here, we review recent progress in the field and contrast the various strategies used in recognition and behavioural networking. PMID- 29194917 TI - Treatment of clozapine-associated obesity and diabetes with exenatide in adults with schizophrenia: A randomized controlled trial (CODEX). AB - Clozapine causes obesity and type 2 diabetes (T2DM). Glucagon-like peptide-1 (GLP 1) receptor agonists (e.g. exenatide) can counter clozapine-associated GLP-1 dysregulation in animals, and may be beneficial in people on clozapine. This randomized, controlled, open-label, pilot trial evaluated weekly exenatide for weight loss among clozapine-treated obese adults with schizophrenia, with or without T2DM. A total of 28 outpatients were randomized to once-weekly extended release subcutaneous exenatide or usual care for 24 weeks. The primary outcome was proportion of participants with >5% weight loss. All 28 participants completed the study; 3/14 in the exenatide group and 2/14 in the usual care group had T2DM. Six people on exenatide achieved >5% weight loss vs one receiving usual care (P = .029). Compared with usual care, participants on exenatide had greater mean weight loss (-5.29 vs -1.12 kg; P = .015) and body mass index reduction ( 1.78 vs -0.39 kg/m2 ; P = .019), and reduced fasting glucose (-0.34 vs 0.39 mmol/L; P = .036) and glycated haemoglobin levels (-0.21% vs 0.03%; P = .004). There were no significant differences in other metabolic syndrome components. Exenatide may be a promising therapeutic agent for glycaemic control and weight loss in clozapine-treated people with obesity, and could assist in reducing clozapine-associated cardio-metabolic morbidity and mortality.

The impact of obesity in critically ill cirrhotic patients with sepsis/septic shock has not been evaluated. This study aimed to examine the relationship between obesity and mortality in cirrhotic patients admitted to the intensive care unit with septic shock. METHODS: A retrospective cohort study of all cirrhotic patients with septic shock (n = 362) and a recorded body mass index (BMI) from an international, multicentre (CATSS) database (1996-2015) was performed. Patients were classified by BMI as per WHO categories. Primary outcome was in-hospital mortality. Multivariate logistic regression analyses were carried out to determine independent associations with outcome. RESULTS: In this analysis, mean age was 56.4 years, and 62% were male. Median BMI was 26.3%, and 57.7% were overweight/obese. In-hospital mortality was 71%. Obese patients were more likely to have comorbidities of cardiac disease, lung disease and diabetes. Compared to survivors (n = 105), non-survivors (n = 257) had significantly higher MELD and APACHEII scores and higher requirements for renal replacement therapy and mechanical ventilation (P < .03 for all). Using multivariable logistic regression, increase in BMI (OR 1.07, P = .034), time delay to appropriate antimicrobials (OR 1.16 per hour, P = .003), APACHEII (OR 1.12 per unit, P = .008) and peak lactate (OR 1.15, P = .028) were independently associated with in hospital mortality. CONCLUSIONS: Septic shock in cirrhosis carries a high mortality. Increased BMI is common in critically ill cirrhotic patients and independently associated with increased in-hospital mortality.

Such knowledge is not only of theoretical interest but is critical to inform management actions under climate change, such as assisted translocation and targeted gene flow. Unfortunately, there are a vast number of potential trait-environment combinations, and simple relationships between trait and environment are ambiguous: representing either plastic or evolved variation. Here, we show that by incorporating connectivity as an index of gene flow, we can differentiate trait-environment relationships reflecting genetic variation vs. phenotypic plasticity. In this way, we rapidly shorten the list of trait-environment combinations that are of significance. Our analysis of an existing data set on geographic variation in a tropical lizard shows that we can effectively rank climatic variables by the strength of their role in local adaptation. The promise of our method is a rapid and general approach to identifying the environmental drivers of local adaptation. PMID- 29194920 TI - para-Xylene Ultra-selective Zeolite MFI Membranes Fabricated from Nanosheet Monolayers at the Air-Water Interface. AB - The control of membrane morphology and microstructure is crucial to improve the separation performance of molecular-sieve membranes. This can be enabled by making thin, dense, and uniform seed-crystal coatings, which are then intergrown into continuous membranes. Herein, we show a novel and simple floating particle coating method can give closely packed monolayers of zeolite nanosheets on nonporous or porous supports. The zeolite nanosheet monolayer is formed at the air-water interface in a conical Teflon trough. As the water in the trough is drained, the monolayer is deposited on a support placed below. Membranes prepared by gel-free secondary growth of the nanosheets deposited by this method show unprecedented ultra-selective performance for separation of para- from ortho xylene (separation factor >10 000). PMID- 29194919 TI - A novel Chromatiales bacterium is a potential sulfide oxidizer in multiple orders of marine sponges. AB - Sponges are benthic filter feeders that play pivotal roles in coupling benthic pelagic processes in the oceans that involve transformation of dissolved and particulate organic carbon and nitrogen into biomass. While the contribution of sponge holobionts to the nitrogen cycle has been recognized in past years, their importance in the sulfur cycle, both oceanic and physiological, has only recently gained attention. Sponges in general, and Theonella swinhoei in particular, harbour a multitude of associated microorganisms that could affect sulfur cycling within the holobiont. We reconstructed the genome of a Chromatiales (class Gammaproteobacteria) bacterium from a metagenomic sequence dataset of a T. swinhoei-associated microbial community. This relatively abundant bacterium has the metabolic capability to oxidize sulfide yet displays reduced metabolic potential suggestive of its lifestyle as an obligatory symbiont. This bacterium was detected in multiple sponge orders, according to similarities in key genes such as 16S rRNA and polyketide synthase genes. Due to its sulfide oxidation metabolism and occurrence in many members of the Porifera phylum, we suggest naming the newly described taxon Candidatus Porisulfidus. PMID- 29194921 TI - Causal beliefs in people experiencing psychosis: The relationship to treatment accessed and the perceived helpfulness of treatment. AB - PURPOSE: Research suggests that the way an individual understands a health difficulty can influence their subsequent behaviour. The aim of this study was to explore the psychometric properties of a new causal belief questionnaire for people who have experience of psychosis. We also planned to provide an overview of current causal beliefs within this group and to explore the relationship between these beliefs and the perceived helpfulness of treatment and the treatment accessed. METHODS: Three hundred and eleven service-users with experience of psychosis completed a questionnaire designed to explore how they understand the cause of their difficulties. Additional information was collected about different aspects of treatment. RESULTS: The results of the exploratory factor analysis indicated a two-factor solution comprising a psychosocial and biogenetic scale. Individuals in this study endorsed a variety of different causes, with an overall preference for psychosocial explanations. No relationships were established between beliefs and perceptions about the helpfulness of treatment. Individuals who had accessed cognitive behavioural therapy were more likely to endorse the psychosocial factor. CONCLUSIONS: Individuals with psychosis consider a number of factors to be important in relation to the development of their experiences. These beliefs should be explored as part of the therapeutic process as this appears to be important to the individual and could potentially help inform treatment decisions. PRACTITIONER POINTS: The causal belief questionnaire captured two underlying constructs relating to psychosocial and biogenetic causes. Individuals within this group endorsed a range of factors; however, they prefer psychosocial causes overall. There was an indication that some aspects of an individual's beliefs were associated with the treatment they accessed. PMID- 29194922 TI - Material properties determining the insecticidal activity of highly divided porous materials on the pharaoh ant (Monomorium pharaonis). AB - BACKGROUND: Historically, inert insecticidal powders such as diatomaceous earth were researched for pest management applications, and it was revealed that these types of powders killed insects by desiccation. However, data on the critical material properties that affect their efficacy are sparse. The present study investigated the insecticidal effect of powdered materials on the pharaoh ant, a notorious domestic pest. RESULTS: The insecticidal activity of 24 porous materials was tested. Eight of these materials performed better than the benchmark, diatomaceous earth. Zeolite Y and carbon black II performed best, inducing 50% mortality within 40 and 55 minutes, respectively. Statistical analysis of seven material properties revealed that macroporous surface area and Brunauer-Emmett-Teller (BET) specific surface area were most predictive of insecticidal activity. For zeolites and ordered mesoporous silica materials, the most important parameters were, respectively, BET and large mesopore surface area. Finally, gas chromatography-mass spectrometry (GC-MS) analysis confirmed the adsorption of epicuticular hydrocarbons onto the zeolite powders. CONCLUSION: This study shows clear potential for the use of environmentally friendly, inert porous materials as insecticides against the pharaoh ant and identified the key material properties influencing insecticidal activity. The GC-MS data support the hypothesis that the mortality was caused by the removal of the protective epicuticular hydrocarbons. (c) 2017 Society of Chemical Industry. PMID- 29194923 TI - Tracking active groundwater microbes with D2 O labelling to understand their ecosystem function. AB - Microbial activity is key in understanding the contribution of microbial communities to ecosystem functions. Metabolic labelling with heavy water (D2 O) leads to the formation of carbon-deuterium bonds in active microorganisms. We illustrated how D2 O labelling allows monitoring of metabolic activity combined with a functional characterization of active populations in complex microbial communities. First, we demonstrated by single cell Raman microspectroscopy that all measured bacterial cells from groundwater isolates growing in complex medium with D2 O were labelled. Next, we conducted a labelling approach with the total groundwater microbiome in D2 O amended microcosms. Deuterium was incorporated in most measured cells, indicating metabolic activity in the oligotrophic groundwater. Moreover, we spiked the groundwater microbiome with organic model compounds. We discovered that heterotrophs assimilating veratric acid, a lignin derivative, showed higher labelling than heterotrophs assimilating methylamine, a degradation product of biomass. This difference can be explained by dilution of the deuterium through hydrogen from the organic compounds. Metaproteomics identified Sphingomonadaceae and Microbacteriaceae as key players in veratric acid degradation, and the metabolic pathways employed. Methylamine, in contrast, stimulated various proteobacterial genera. We propose this combined approach of Raman microspectroscopy and metaproteomics for elucidating the complex metabolic response of microbial populations to different stimuli.

AB - OBJECTIVES: To measure microleakage around zirconia crown margins cemented with self-adhesive resin or resin modified glass ionomer (RMGI) cement after ultrasonic scaling. METHODS: 16 molars were prepared for crowns (margin 0.5 mm coronal of cementum-enamel junction). Preparations were digitally scanned and zirconia crowns milled. Specimens were divided into two groups (n = 8): self adhesive resin (RelyX Unicem 2) or resin modified glass ionomer (RMGI) (RelyX Luting Plus) cements. After cementation, specimens were ultrasonic scaled with a piezoelectric device (60 s, hand pressure). After thermocycling (20,000 cycles/5 55 degrees C), specimens were immersed in 5 wt% fuchsine dye before sectioning bucco-lingually. Microleakage was examined under 40* light magnification. Statistical comparisons were made using a paired t test and a two-sample t test (alpha = .05). RESULTS: Ultrasonic scaling did not alter microleakage at the margins of crowns (P = .31). There was no significant difference in microleakage of scaled and untreated margins with the use of different cements (P = .21). The amount of microleakage around margins that were scaled was not significantly different between cements (P = .14). Untreated margins of crowns cemented with RelyX Luting Plus showed a significantly higher microleakage than those cemented with RelyX Unicem 2 (P = .005). CONCLUSIONS: Piezoelectric ultrasonic scaling did not increase microleakage at the margin of zirconia crowns cemented with self adhesive resin or RMGI cements. CLINICAL SIGNIFICANCE: Piezoelectric ultrasonic scaling around zirconia crowns did not impact marginal microleakage cemented with self-adhesive resin or RMGI cements.

PMID- 29194926 TI - Survivors of Child Maltreatment and Postpartum Depression: An Integrative Review. AB - INTRODUCTION: An integrative review was performed to explore the relationship between a maternal history of child maltreatment and subsequent postpartum depression (PPD) symptoms. METHODS: Six electronic databases were used to explore the literature, including PubMed, CINAHL, MEDLINE, PsycINFO, Embase, and Scopus. Studies were included that used victims of child maltreatment as one of the independent variables and PPD symptoms as one of the dependent variables. Studies were excluded if they focused only on women with adult intimate partner violence or women with PPD who were perpetrators of child abuse rather than survivors. The studies were required to be original research, and there was no limit to years or language. The search yielded 589 studies, 16 of which were included in the final sample. These studies were assessed for quality, and a data display matrix was developed to extract the sample, design, methods, operational definitions for independent and dependent variables of interest, major findings with effect sizes, and limitations. Using the data display matrix, the studies' methods and findings were synthesized for divergent and convergent patterns. RESULTS: Studies were varied in their designs, samples, and operational definitions of child maltreatment and PPD, and were low to moderate in quality. Results were inconsistent, but a majority suggest a positive association between a maternal history of child maltreatment and subsequent symptoms of PPD. DISCUSSION: Child maltreatment and PPD are complex issues that require careful screening by women's health care providers and clearly defined operational definitions in future research. Implications for clinical practice and research are discussed. PMID- 29194927 TI - Computer guided sinus floor elevation through lateral window approach with simultaneous implant placement. AB - BACKGROUND: The introduction of CAD/CAM technology in implant dentistry has marked a new era, allowing various procedures to be carried out with a level of great precision and accuracy. PURPOSE: The aim of the present study is to compare the efficacy of a CAD/CAM generated surgical cutting guide in the reduction of incidence of membrane perforation during maxillary sinus floor elevation in relation to the standard lateral window approach technique. MATERIALS AND METHODS: Twenty cases of maxillary sinus elevation were randomly divided into 2 groups. The first group received computer guided sinus floor elevation through lateral window approach and simultaneous implant placement while the second group received standard sinus elevation procedure through lateral window approach with simultaneous implant placement. RESULTS: In the computer guided group, 3 out of 10 cases presented with sinus septa, only 1 case suffered from membrane perforation during the elevation process. In the non-guided group, 3 cases suffered from membrane perforation, 2 of which were complicated by sinus septa. CONCLUSION: Within the limits of this study, computer guided sinus floor elevation showed promising results in accurately modifying the lateral window osteotomy and presents as a safe alternative to the standard technique. PMID- 29194928 TI - Clinical pathway improves implementation of evidence-based strategies for the management of androgen deprivation therapy-induced side effects in men with prostate cancer. AB - OBJECTIVES: To assess the effects of a prostate cancer (PCa) clinical pathway on the implementation of evidence-based strategies for the management of androgen deprivation therapy (ADT)-induced side effects. PATIENTS AND METHODS: A clinical pathway was introduced at hospital level in 2015. The pathway consists of evidence-based strategies for the management of ADT-induced side effects. All patients with PCa receiving ADT for >6 months were eligible to enter the clinical pathway. Data on recommended evidence-based strategies were retrospectively extracted from the electronic health records of all eligible patients in the year before (2014) and the year of implementation of the pathway (2015). Descriptive statistics were used for patient characteristics. The chi-squared test (or Fisher's exact test) and Mann-Whitney U-test were used to compare results in the control group with those in the intervention group. RESULTS: In total, 126 patients were included in the control group and 132 patients in the intervention group. Baseline patient characteristics were well balanced. After implementation of the pathway, metabolic, bone and cardiac risk assessment screenings were more frequently applied in the intervention group (metabolic 46% vs 4%; bone 58% vs 10%; cardiac 61% vs 16%; P < 0.001). Advice on strategies preventing ADT-induced side effects was more frequently provided in the intervention group (exercise 62% vs 11%; nutrition 58% vs 10%; psycho-education 54% vs 13%; P < 0.001). CONCLUSION: A clinical pathway for patients with PCa improved the implementation of evidence-based strategies for the management of ADT-induced side effects. A clinical pathway could serve as a method to bridge the gap between evidence-based guidelines and daily clinical practice. PMID- 29194929 TI - Procarboxypeptidase U (proCPU, TAFI, proCPB2) in cerebrospinal fluid during ischemic stroke is associated with stroke progression, outcome and blood-brain barrier dysfunction. AB - : Essentials Little is known of procarboxypeptidase U (proCPU) in cerebrospinal fluid (CSF) of stroke patients. ProCPU levels were studied in CSF of controls and non-thrombolyzed acute ischemic stroke patients. ProCPU is elevated in CSF of stroke patients compared with controls. ProCPU in CSF correlates with stroke progression, outcome, and blood-brain barrier dysfunction. SUMMARY: Background Procarboxypeptidase U (proCPU, TAFI, proCPB2), the zymogen of CPU, which is a potent antifibrinolytic enzyme and a modulator of inflammation, has previously been investigated in plasma of stroke patients, but so far, no information on the proCPU levels in cerebrospinal fluid (CSF) during acute ischemic stroke (AIS) is available. Objectives This case-control observational study investigates proCPU in CSF of AIS patients compared with controls with an intact blood-brain barrier (BBB) and evaluates the relationship of CSF/plasma proCPU ratios with stroke parameters. Methods A sensitive HPLC-based enzymatic assay was used to determine proCPU levels in CSF of non-thrombolyzed patients in the hyperacute phase (< 24 h after onset) of AIS (n = 72). Individuals (n = 32) without stroke, an intact BBB and no apparent abnormalities in biochemical and microbiological tests, served as controls. Relations between the CSF/plasma proCPU ratio and (i) stroke severity, (ii) stroke progression/recurrence, (iii) stroke outcome and (iv) BBB dysfunction (CSF/serum albumin ratio) were assessed. Results Mean (SEM) proCPU levels were elevated in the CSF of stroke patients compared with controls (4.36 (0.23) U L-1 vs. 3.50 (0.23) U L-1 ). Higher median [IQR] CSF/plasma proCPU ratios were found in patients with stroke progression ((6.0 [4.2-6.9]) * 10-3 ) and poor outcome ((6.4 [3.9-7.0]) * 10-3 ) after 3 months (modified Rankin Scale; mRS > 3) compared with patients without progression ((3.9 [2.7-5.4]) * 10-3 ) or better outcome ((4.0 [2.8-5.0]) * 10-3 ). In stroke patients with a disrupted BBB, proCPU ratios were higher compared with stroke patients with an intact BBB ((6.4 [5.8-9.0]) * 10-3 vs. (3.7 [2.8-5.0]) * 10-3 ). Conclusions ProCPU is increased in CSF during hyperacute ischemic stroke and is associated with stroke progression and outcome after 3 months, most likely due to BBB dysfunction in the hyperacute phase of ischemic stroke. PMID- 29194930 TI - Metabolic versatility of a novel N2 -fixing Alphaproteobacterium isolated from a marine oxygen minimum zone. AB - The N2 -fixing (diazotrophic) community in marine ecosystems is dominated by non cyanobacterial microorganisms. Yet, very little is known about their identity, function and ecological relevance due to a lack of cultured representatives. Here we report a novel heterotrophic diazotroph isolated from the oxygen minimum zone (OMZ) off Peru. The new species belongs to the genus Sagittula (Rhodobacteraceae, Alphaproteobacteria) and its capability to fix N2 was confirmed in laboratory experiments. Genome sequencing revealed that it is a strict heterotroph with a high versatility in substrate utilization and energy acquisition mechanisms. Pathways for sulfide oxidation and nitrite reduction to nitrous oxide are encoded in the genome and might explain the presence throughout the Peruvian OMZ. The genome further indicates that this novel organism could be in direct interaction with other microbes or particles. NanoSIMS analyses were used to compare the metabolic potential of S. castanea with single-cell activity in situ; however, N2 fixation by this diazotroph could not be detected at the isolation site. While the biogeochemical impact of S. castanea is yet to be resolved, its abundance and widespread distribution suggests that its potential to contribute to the marine N input could be significant at a larger geographical scale. PMID- 29194931 TI - Antibiotic resistome in a large-scale healthy human gut microbiota deciphered by metagenomic and network analyses. AB - The human gut microbiota is an important reservoir of antibiotic resistance genes (ARGs). A metagenomic approach and network analysis were used to establish a comprehensive antibiotic resistome catalog and to obtain co-occurrence patterns between ARGs and microbial taxa in fecal samples from 180 healthy individuals from 11 different countries. In total, 507 ARG subtypes belonging to 20 ARG types were detected with abundances ranging from 7.12 * 10-7 to 2.72 * 10-1 copy of ARG/copy of 16S-rRNA gene. Tetracycline, multidrug, macrolide-lincosamide streptogramin, bacitracin, vancomycin, beta-lactam and aminoglycoside resistance genes were the top seven most abundant ARG types. The multidrug ABC transporter, aadE, bacA, acrB, tetM, tetW, vanR and vanS were shared by all 180 individuals, suggesting their common occurrence in the human gut. Compared to populations from the other 10 countries, the Chinese population harboured the most abundant ARGs. Moreover, LEfSe analysis suggested that the MLS resistance type and its subtype 'ermF' were representative ARGs of the Chinese population. Antibiotic inactivation, antibiotic target alteration and antibiotic efflux were the dominant resistance mechanism categories in all populations. Procrustes analysis revealed that microbial phylogeny structured the antibiotic resistome. Co occurrence patterns obtained via network analysis implied that 12 species might be potential hosts of 58 ARG subtypes. PMID- 29194932 TI - Paper-Based Polymer Electrodes for Bioanalysis and Electrochemistry of Neurotransmitters. AB - This article describes the preparation and characterization of PEDOT-coated paper electrodes. Their specific behavior was investigated, especially the impact of electrode shape on the electrochemical properties. It was found that different electrode geometries promote different results, largely because of a potential drop in the bulk of the electrode material. More importantly, the suitability of these substrates for bio- and neurochemical analyses was investigated. The paper electrodes were found to offer better resistance to both protein and neurotransmitter foulings, in comparison to a planar electrode. Interestingly, long paper electrodes were more stable during sustained oxidation of dopamine and serotonin than short ones, possibly because of the conjunction of surface passivation and potential drop allowing for the site of oxidation to move along the electrode as fouling progresses. PMID- 29194933 TI - Association of metabolic syndrome with carotid thickening and plaque in the general population: A meta-analysis. AB - We performed a meta-analysis of population studies reporting data on carotid intima-media thickness and plaque in patients with and without metabolic syndrome (MetS) to provide a new piece of information on the relationship of MetS with both phenotypes of vascular damage. The Ovid MEDLINE, PubMed, and Cochrane CENTRAL databases were searched without time restriction up to December 31, 2016. Overall, 19 696 patients (22.2% with MetS) were included in eight studies. Common carotid intima-media thickness was greater in patients with MetS compared with those without it (788 +/- 47 MUm vs 727 +/- 44 MUm), with a standard means difference of 0.28 +/- 0.06 (P = .00003). Increased intima-media thickness in patients with MetS was paralleled by a higher prevalence of plaques. The present meta-analysis shows that MetS is associated with both ultrasonographic phenotypes of carotid damage. This finding is consistent with the view of MetS as a cluster of hemodynamic and nonhemodynamic factors promoting vascular hypertrophy and plaque. PMID- 29194934 TI - Hypergammaglobulinemia is a strong predictor of disease progression, hepatocellular carcinoma, and death in patients with compensated cirrhosis. AB - BACKGROUND & AIMS: The outcome of compensated cirrhosis may vary considerably and cannot be predicted by routinely performed tests at present. The aim of this study was to evaluate possible predictors of clinical evolution in patients with Child-Pugh (C-P) class A cirrhosis because of untreatable causes by analysing clinical/biochemical/instrumental parameters evaluated at the time of diagnosis and during the subsequent long-lasting follow-up. METHODS: Two hundred and seventy-two consecutive C-P class A cirrhotic patients (155 males; median age 63 years, range 34-81) were analysed. All patients were followed up for a median time of 96 months (range 21-144) through periodically performed clinical/biochemical/ultrasonographic and esophagogastroduodenoscopic examinations. RESULTS: During the follow-up, 97 individuals (36%) were clinically stable, 104 (38%) developed hepatocellular carcinoma (HCC) and 71 (26%) progressed towards C-P class B/C without developing cancer. One hundred and thirty-one patients (48%) died or underwent liver transplantation. Multivariate regression analysis showed that clinical stability was significantly associated with older age (P < .001), the absence of diabetes (P = .04) and of oesophageal varices (P < .001), serum albumin >3.5 gr/dL (P = .01) and gamma globulin <1.8 gr/dL (P = .01). HCC development was significantly associated with younger age (P = .01) and serum gamma globulin values >=1.8 gr/dL (P < .001). C-P score progression was associated with oesophageal varices (P < .001), lower serum albumin (P = .03) and cholesterol (P = .01) values, and hypergammaglobulinemia (P = .02). Death was associated with younger age (P < .001) and hypergammaglobulinemia (P = .01). Multivariate Cox regression analysis and Kaplan Meier's survival test confirmed that gammaglobulinemia >=1.8 g/dL was a significant predictor of death (P < .02, and P < .01 respectively). CONCLUSIONS: Hypergammaglobulinemia identifies C-P class A cirrhotic patients at higher risk of disease progression, HCC development and death.

PMID- 29194936 TI - Spinosad-mediated effects on the walking ability, midgut, and Malpighian tubules of Africanized honey bee workers. AB - BACKGROUND: The global decline in Apis mellifera colonies is attributed to multiple factors, including pesticides. The bioinsecticide spinosad was initially recognized as safe for non-target organisms; however, its toxicity has been changing this view. Here, we investigated the survival, behavioral changes, and structural changes in the midgut and Malpighian tubules of A. mellifera treated orally with a spinosad formulation. RESULTS: The field-recommended concentration of spinosad killed 100% of the bees. The 5% and 50% lethal concentrations (LC5 and LC50 , respectively) of spinosad altered the behavioral activity, reducing the walking distance and velocity, and increased the resting time in comparison to the control. The LC50 caused disorganization of the epithelia of tested organs and induced oxidative stress and cell death. CONCLUSIONS: The present work provides new insights into the debate about the role of bioinsecticides in the mortality of Africanized honey bees. Even at very low concentrations, the spinosad formulation was toxic to the vital organs midgut and Malpighian tubules and adversely affected walking behavior. This detailed evaluation of the impact of the bioinsecticide on A. mellifera will contribute to the clarification of disturbances probably caused by spinosad formulations, which can be used to develop more sustainable protocols in agriculture.

AB - BACKGROUND: An age-related decrease in the number of osteogenic progenitor cells may compromise bone augmentation. PURPOSE: Histomorphometrical assessment of age related new bone formation, following atrophic alveolar ridge reconstruction, using cancellous bone-block allografts. MATERIAL AND METHODS: Ninety-three consecutive patients (58 females and 35 males) were referred for implant supported restoration of 122 severe atrophic alveolar ridges. Alveolar ridge deficiency locations were classified as anterior maxilla (n = 58), posterior maxilla (n= 32), and posterior mandible (n = 32). A bony deficiency of at least 3 mm horizontally and up to 3 mm vertically according to computerized tomography (CT) in the posterior mandible and anterior maxilla, served as inclusion criteria. In the posterior maxilla, a residual alveolar ridge up to 4 mm vertically according to CT served as inclusion criteria. Augmentation was performed by the use of cancellous bone-block allografts. Bone biopsies (9-month posterior maxilla, 4 months anterior maxilla and posterior mandible) of young (<=40 years) versus older (>40 years) patients were histomorphometrically evaluated. RESULTS: In the posterior maxilla, no statistically significant histomorphometric differences were noted. While at the anterior maxilla and posterior mandible, statistically significant more newly formed bone was found in young versus older individuals, respectively (38.6% vs 19.8%, P = 0.04 and 69% vs 31%, P = .05). CONCLUSION: New bone formation following residual alveolar ridge bone grafting is age-related. Longer bone consolidation and healing time may be recommended for older individuals.

AB - With this personal account we show how the Integrative Chemistry, when combining the sol-gel process and concentrated emulsions, allows to trigger inorganic, hybrid or living materials when dedicated toward heterogeneous catalysis applications. In here we focus on 3D-macrocellular monolithic foams bearing hierarchical porosities and applications thereof toward heterogeneous catalysis where both activities and mass transport are enhanced. We thereby first depict the general background of emulsions, focusing on concentrated ones, acting as soft templates for the design of solid (HIPE) foams, HIPE being the acronym for High Internal Phase Emulsions while encompassing both sol-gel and polymer chemistry. Secondly we extend this approach toward the design of inorganic cellular materials labeled Si(HIPE) and hybrid organic-inorganic foams, labeled Organo-Si(HIPE), where heterogeneous catalysis applications are addressed considering acidic, metallic, enzymatic and bacterial-based modified Si-HIPE. Along, we will show how the fluid hydrodynamic within the macrocellular foams is offering advanced "out of the box" heterogeneous catalytic capabilities.

PMID- 29194940 TI - The development of a 4D treatment planning methodology to simulate the tracking of central lung tumors in an MRI-linac. AB - PURPOSE: Targeting and tracking of central lung tumors may be feasible on the Elekta MRI-linac (MRL) due to the soft-tissue visualization capabilities of MRI. The purpose of this work is to develop a novel treatment planning methodology to simulate tracking of central lung tumors with the MRL and to quantify the benefits in OAR sparing compared with the ITV approach. METHODS: Full 4D-CT datasets for five central lung cancer patients were selected to simulate the condition of having 4D-pseudo-CTs derived from 4D-MRI data available on the MRL with real-time tracking capabilities. We used the MRL treatment planning system to generate two plans: (a) with a set of MLC-defined apertures around the target at each phase of the breathing ("4D-MRL" method); (b) with a fixed set of fields encompassing the maximum inhale and exhale of the breathing cycle ("ITV" method). For both plans, dose accumulation was performed onto a reference phase. To further study the potential benefits of a 4D-MRL method, the results were stratified by tumor motion amplitude, OAR-to-tumor proximity, and the relative OAR motion (ROM). RESULTS: With the 4D-MRL method, the reduction in mean doses was up to 3.0 Gy and 1.9 Gy for the heart and the lung. Moreover, the lung's V12.5 Gy was spared by a maximum of 300 cc. Maximum doses to serial organs were reduced by up to 6.1 Gy, 1.5 Gy, and 9.0 Gy for the esophagus, spinal cord, and the trachea, respectively. OAR dose reduction with our method depended on the tumor motion amplitude and the ROM. Some OARs with large ROMs and in close proximity to the tumor benefited from tracking despite small tumor amplitudes. CONCLUSIONS: We developed a novel 4D tracking methodology for the MRL for central lung tumors and quantified the potential dosimetric benefits compared with our current ITV approach. PMID- 29194942 TI - RNA interference technology in crop protection against arthropod pests, pathogens and nematodes. AB - Scientists have made significant progress in understanding and unraveling several aspects of double-stranded RNA (dsRNA)-mediated gene silencing during the last two decades. Now that the RNA interference (RNAi) mechanism is well understood, it is time to consider how to apply the acquired knowledge to agriculture and crop protection. Some RNAi-based products are already available for farmers and more are expected to reach the market soon. Tailor-made dsRNA as an active ingredient for biopesticide formulations is considered a raw material that can be used for diverse purposes, from pest control and bee protection against viruses to pesticide resistance management. The RNAi mechanism works at the messenger RNA (mRNA) level, exploiting a sequence-dependent mode of action, which makes it unique in potency and selectivity compared with conventional agrochemicals. Furthermore, the use of RNAi in crop protection can be achieved by employing plant-incorporated protectants through plant transformation, but also by non transformative strategies such as the use of formulations of sprayable RNAs as direct control agents, resistance factor repressors or developmental disruptors. In this review, RNAi is presented in an agricultural context (discussing products that have been launched on the market or will soon be available), and we go beyond the classical presentation of successful examples of RNAi in pest-insect control and comprehensively explore its potential for the control of plant pathogens, nematodes and mites, and to fight against diseases and parasites in beneficial insects. Moreover, we also discuss its use as a repressor for the management of pesticide-resistant weeds and insects. Finally, this review reports on the advances in non-transformative dsRNA delivery and the production costs of dsRNA, and discusses environmental considerations. (c) 2017 Society of Chemical Industry.

AB - BACKGROUND: The primary stability of dental implants can be evaluated by insertion torque (IT) and resonance frequency analysis (RFA). OBJECTIVE: Assess the supposed relationship between the IT and RFA. MATERIALS AND METHODS: A systematic review was performed based on the PRISMA. The electronic search was performed in the PubMed, Web of Science, SCOPUS, Cochrane Library electronic, OVID, and Scielo databases. Manual searches were also performed. There was no restrictions regarding year of publication or language. The articles identified were assessed independently by 3 trained researchers. Clinical trials reporting the RFA values by means of implant stability quotient (ISQ) and IT were included. RESULTS: The electronic and manual searches yielded 2017 studies. Twelve studies were included in the systematic review. There was no statistically significant correlation between ISQ and IT (rs = .366; P = .079). The quality of the evidence was downgraded by risk of bias and indirectness; and the certainty of the evidence was low. CONCLUSION: IT and RFA are independent and incomparable methods of measuring primary stability. Is important for clinicians to define only one method of evaluation for each implant.

AB - The development of effective approaches for preparing large-area, self-standing, ultrathin metal-based nanosheets, which have proved to be favorable for catalytic applications such as water electrolysis, is highly desirable but remains a great challenge. Reported herein is a simple and versatile strategy to synthesize ultrathin Co3 O4 and CoP NSs consisting of close-packed nanoparticles by pyrolyzing cobalt(II) phthalocyanine/graphene oxide (CoPc/GO) assemblies in air and subsequent topotactic phosphidation while preserving the graphene-like morphology. The strong pi-pi stacking interactions between CoPc and GO, and the inhibiting effect of the tetrapyrrole-derived macrocycle for grain growth during the catalytic carbon gasification contribute to the NSs forming. The resulting homologous Co3 O4 and CoP NSs display outstanding catalytic activity in alkaline media toward the oxygen evolution reaction and the hydrogen evolution reaction, respectively, ascribed to the richly exposed active sites, and the expedited electrolyte/ion transmission path. The integrated asymmetrical two-electrode configuration also presents a superior cell voltage of 1.63 V at 10 mA cm-2 for overall water splitting, accompanied with the excellent durability during long term cycling. Further evidences validate that this strategy is appropriate to fabricate graphene-like ultrathin NSs of many other metal oxides, such as Fe2 O3 , NiO, MoO3 , and mixed-metal oxides, for various applications.

AB - Materials based upon hexa-peri-hexabenzocoronenes (HBCs) show significant promise in a variety of photovoltaic applications. There remains the need, however, for a soluble, versatile, HBC-based platform, which can be tailored by incorporation of electroactive groups or groups that can prompt self-assembly. The synthesis of a HBC-fluorene hybrid is presented that contains an expanded graphitic core that is highly soluble, resists aggregation, and can be readily functionalized at its vertices. This new HBC platform can be tailored to incorporate six electroactive groups at its vertices, as exemplified by a facile synthesis of a representative hexaaryl derivative of FHBC. Synthesis of new FHBC derivatives, containing electroactive functional groups that can allow controlled self-assembly, may serve as potential long-range charge-transfer materials for photovoltaic applications.

AB - OBJECTIVES: Direct-acting antivirals (DAAs) for treatment of chronic hepatitis C virus (HCV) infection can cause drug-drug interactions (DDIs) with combination antiretroviral therapy (cART) and non-cART co-medication. We mapped how physicians manage DDIs between DAAs and co-medication and analysed treatment outcomes. METHODS: Data were prospectively collected as part of the ATHENA HIV observational cohort and retrospectively analysed. Dutch patients with HIV/HCV coinfection who initiated treatment with DAAs between January 2015 and May 2016 were included. Co-medication 3 months prior to and during DAA therapy was identified. Potential DDIs with the DAAs were checked using http://hep druginteractions.org. DDIs were categorized as: (1) no interaction expected; (2) potential interaction; (3) contra-indication; (4) no recommendation. These categories were used to determine which patients switched or had a DDI during DAA therapy with co-medication. RESULTS: A total of 423 patients were treated with DAAs, of whom 418 (99%) used cART and 251 (59%) used non-cART co-medication. Before commencing DAA treatment, in 17 of 84 (20%) patients the non-cART co medication which could result in a category 2/3 DDI was discontinued before DAA initiation, including two of six (33%) prescriptions of category 3 drugs. A total of 196 of 418 (47%) patients had a category 2/3 DDI between their DAA regimen and cART. Category 2/3 DDIs were prevented by switching cART in 78 of 147 (53%) and 47 of 49 (98%) patients. Overall, 367 of 423 (87%) patients have achieved a sustained virological response (33 in follow-up). CONCLUSIONS: Prescription patterns suggest that physicians are aware of potential DDIs between co medication and DAAs, in particular potential DDIs with cART. Greater awareness is needed concerning category 3 interactions between non-cART co-medication and DAAs.

AB - Chemical examination of the bright yellow sponge Leucetta chagosensis resulted in the isolation of three new imidazole-based alkaloid complexes namely chagosendines A - C (1 - 3), together with known analogues pyronaamidine, naamidine J, and naamine C. Their structures were determined on the basis of extensive spectroscopic (IR, MS, NMR, and single-crystal X-ray diffraction) analysis in association with the chemical conversion. The isolated alkaloids together with three synthesized new homodimer complexes were evaluated for the cytotoxic activities against a panel of tumor cell lines. The copper complexes of imidazole alkaloids 2 and 3, as found from nature for the first time, exerted selective and remarkable activities against the tumor cell lines K562, HepG2, and HeLa. PMID- 29194949 TI - Metabolism of 2,4-dichlorophenoxyacetic acid contributes to resistance in a common waterhemp (Amaranthus tuberculatus) population. AB - BACKGROUND: Synthetic auxins such as 2,4-dichlorophenoxyacetic acid (2,4-D) have been widely used for selective control of broadleaf weeds since the mid-1940s. In 2009, an Amaranthus tuberculatus (common waterhemp) population with 10-fold resistance to 2,4-D was found in Nebraska, USA. The 2,4-D resistance mechanism was examined by conducting [14 C] 2,4-D absorption, translocation and metabolism experiments. RESULTS: No differences were found in 2,4-D absorption or translocation between resistant and susceptible A. tuberculatus plants. Resistant plants metabolized [14 C] 2,4-D more rapidly than did susceptible plants. The half-life of [14 C] 2,4-D in susceptible plants was 105 h, compared with 22 h in resistant plants. Pretreatment with the cytochrome P450 inhibitor malathion inhibited [14 C] 2,4-D metabolism in resistant plants and reduced the 2,4-D dose required for 50% growth inhibition (GR50 ) of resistant plants by 7-fold to 27 g ha-1 , similar to the GR50 for susceptible plants in the absence of malathion. CONCLUSION: Our results demonstrate that rapid 2,4-D metabolism is a contributing factor to resistance in A. tuberculatus, potentially mediated by cytochrome P450. Metabolism-based resistance to 2,4-D could pose a serious challenge for A. tuberculatus control because of the potential for cross-resistance to other herbicides.

AB - Reptile embryos have recently been observed moving within the egg in response to temperature, raising the exciting possibility that embryos might behaviorally thermoregulate analogous to adults. However, the conjecture that reptile embryos have ample opportunity and capacity to adaptively control their body temperature warrants further discussion. Using turtles as a model, we discuss the spatiotemporal constraints to movement in reptile embryos. We demonstrate that, as embryos grow, the internal egg space rapidly diminishes such that the temporal window for appreciable displacement is confined to stages that feature incomplete neuromuscular differentiation. During this time, muscles are insufficiently developed to actively and consistently control movement. These constraints are well illustrated by the Chinese softshelled turtle (Pelodiscus sinensis), the first reptile reported to behaviorally thermoregulate. Furthermore, sporadic embryo activity peaks after the temperature-sensitive period in species with temperature-dependent sex determination, thus nullifying the opportunity for embryos to exhibit control over this important phenotype. These embryonic constraints add to previously-identified environmental constraints on behavioral thermoregulation by reptile embryos. We discuss alternative hypotheses to explain previously reported patterns of behavioral thermoregulation. Based on a holistic consideration of embryonic limitations, we conclude that reptile embryos are generally unable to adaptively behaviorally thermoregulate within the egg. PMID- 29194951 TI - Quantification of large scale DNA organization for predicting prostate cancer recurrence. AB - This study investigates whether Genomic Organization at Large Scales (which we propose to call GOALS) as quantified via nuclear phenotype characteristics and cell sociology features (describing cell organization within tissue) collected from prostate tissue microarrays (TMAs) can separate biochemical failure from biochemical nonevidence of disease (BNED) after radical prostatectomy (RP). Of the 78 prostate cancer tissue cores collected from patients treated with RP, 16 who developed biochemical relapse (failure group) and 16 who were BNED patients (nonfailure group) were included in the analyses (36 cores from 32 patients). A section from this TMA was stained stoichiometrically for DNA using the Feulgen Thionin methodology, and scanned with a Pannoramic MIDI scanner. Approximately 110 nuclear phenotypic features, predominately quantifying large scale DNA organization (GOALS), were extracted from each segmented nuclei. In addition, the centers of these segmented nuclei defined a Voronoi tessellation and subsequent architectural analysis. Prostate TMA core classification as biochemical failure or BNED after RP using GOALS features was conducted (a) based on cell type and cell position within the epithelium (all cells, all epithelial cells, epithelial >2 cell layers away from basement membrane) from all cores, and (b) based on epithelial cells more than two cell layers from the basement membrane using a Classifier trained on Gleason 6, 8, 9 (16 cores) only and applied to a Test set consisting of the Gleason 7 cores (20 cores). Successful core classification as biochemical failure or BNED after RP by a linear classifier was 75% using all cells, 83% using all epithelial cells, and 86% using epithelial >2 layers. Overall success of predicted classification by the linear Classifier of (b) was 87.5% using the Training Set and 80% using the Test Set. Overall success of predicted progression using Gleason score alone was 75% for Gleason >7 as failures and 69% for Gleason >6 as failures. (c) 2017 International Society for Advancement of Cytometry. PMID- 29194952 TI - Deltamethrin is metabolized by CYP6FU1, a cytochrome P450 associated with pyrethroid resistance, in Laodelphax striatellus. AB - BACKGROUND: Cytochrome P450s (CYPs) are known to play a major role in metabolizing a wide range compounds. CYP6FU1 has been found to be over-expressed in a deltamethrin-resistant strain of Laodelphax striatellus. This study was conducted to express CYP6FU1 in Sf9 cells as a recombinant protein, to confirm its ability to degrade deltamethrin, chlorpyrifos, imidacloprid and traditional P450 probing substrates. RESULTS: Carbon monoxide difference spectrum analysis indicated that the intact CYP6FU1 protein was expressed in insect Sf9 cells. Catalytic activity tests with four traditional P450 probing substrates revealed that the expressed CYP6FU1 preferentially metabolized p-nitroanisole and ethoxyresorufin, but not ethoxycoumarin and luciferin-HEGE. The enzyme kinetic parameters were tested using p-nitroanisole. The michaelis constant (Km ) and catalytic constant (Kcat ) values were 17.51 +/- 4.29 um and 0.218 +/- 0.001 pmol min-1 mg-1 protein, respectively. Furthermore, CYP6FU1 activity for degradation of insecticides was tested by measuring substrate depletion and metabolite formation. The chromatogram analysis showed obvious nicotinamide-adenine dinucleotide phosphate (NADPH)-dependent depletion of deltamethrin, and formation of the unknown metabolite. Mass spectra and the molecular docking model showed that the metabolite was 4-hydroxy-deltamethrin. However, the recombinant CYP6FU1 could not metabolize imidacloprid and chlorpyrifos. CONCLUSION: These results confirmed that the over-expressed CYP6FU1 contributes to deltamethrin resistance in L. striatellus, and p-nitroanisole might be a potential diagnostic probe for deltamethrin metabolic resistance detection and monitoring.

PMID- 29194955 TI - Incomplete penetrance, variable expressivity, or dosage insensitivity in four families with directly transmitted unbalanced chromosome abnormalities. AB - The direct transmission of microscopically visible unbalanced chromosome abnormalities (UBCAs) is rare and usually has phenotypic consequences. Here we report four families in which a normal phenotype was initially found in one or more family members. Each UBCA was interpreted with regard to overlapping examples and factors previously associated with transmitted imbalances including incidental ascertainment, low gene density, benign copy number variation (CNV) content, and gene relatedness. A 4.56 Mb deletion of 8p23.1-p23.2 was thought to be causal in the affected proband but showed incomplete penetrance in her mother and sibling (Family 1). Incomplete penetrance was also associated with a 10.88 Mb duplication of 13q21.31-q22.1 (Family 3) and dosage insensitivity with a 17.6 Mb deletion of 22pter-q11.21 (Family 4) that were both ascertained at prenatal diagnosis and each found in 4 unaffected family members. The 22pter-q11.21 deletion is part of a region with high benign CNV content and supports the mapping of cat eye syndrome to a 600 kb interval of 22q11.1-q11.21. Low gene densities of less than 2.0 genes/Mb were found in each of these three families but only after segmentally duplicated genes were excluded from the deletions of 8p and 22q. In contrast, gene density was average and variable expressivity associated with a 3.59 Mb duplication of 8p23.1 incidentally ascertained for paternal infertility (Family 2). Our results indicate that a greater degree of direct parental transmission, incomplete penetrance, and variable expression are features of both sub-microscopic CNVs and UBCAs with relatively low gene and high benign CNV content. PMID- 29194950 TI - Multiplex quantitative SILAC for analysis of archaeal proteomes: a case study of oxidative stress responses. AB - Stable isotope labelling of amino acids in cell culture (SILAC) is a quantitative proteomic method that can illuminate new pathways used by cells to adapt to different lifestyles and niches. Archaea, while thriving in extreme environments and accounting for ~20%-40% of the Earth's biomass, have not been analyzed with the full potential of SILAC. Here, we report SILAC for quantitative comparison of archaeal proteomes, using Haloferax volcanii as a model. A double auxotroph was generated that allowed for complete incorporation of 13 C/15 N-lysine and 13 C arginine such that each peptide derived from trypsin digestion was labelled. This strain was found amenable to multiplex SILAC by case study of responses to oxidative stress by hypochlorite. A total of 2565 proteins was identified by LC MS/MS analysis (q-value <= 0.01) that accounted for 64% of the theoretical proteome. Of these, 176 proteins were altered at least 1.5-fold (p-value < 0.05) in abundance during hypochlorite stress. Many of the differential proteins were of unknown function. Those of known function included transcription factor homologs related to oxidative stress by 3D-homology modelling and orthologous group comparisons. Thus, SILAC is found to be an ideal method for quantitative proteomics of archaea that holds promise to unravel gene function. PMID- 29194954 TI - COMT Val158 Met moderates the link between rank and aggression in a non-human primate. AB - The COMT Val158 Met polymorphism is one of the most widely studied genetic polymorphisms in humans implicated in aggression and the moderation of stressful life event effects. We screened a wild primate population for polymorphisms at the COMT Val158 Met site and phenotyped them for aggression to test whether the human polymorphism exists and is associated with variation in aggressive behavior. Subjects were all adults from 4 study groups (37 males, 40 females) of Assamese macaques (Macaca assamensis) in their natural habitat (Phu Khieo Wildlife Sanctuary, Thailand). We collected focal animal behavioral data (27 males, 36 females, 5964 focal hours) and fecal samples for non-invasive DNA analysis. We identified the human COMT Val158 Met polymorphism (14 Met/Met, 41 Val/Met and 22 Val/Val). Preliminary results suggest that COMT genotype and dominance rank interact to influence aggression rates. Aggression rates increased with rank in Val/Val, but decreased in Met/Met and Val/Met individuals, with no significant main effect of COMT genotype on aggression. Further support for the interaction effect comes from time series analyses revealing that when changing from lower to higher rank position Val/Val individuals decreased, whereas Met/Met individuals increased their aggression rate. Contradicting the interpretation of earlier studies, we show that the widely studied Val158 Met polymorphism in COMT is not unique to humans and yields similar behavioral phenotypes in a non-human primate. This study represents an important step towards understanding individual variation in aggression in a wild primate population and may inform human behavioral geneticists about the evolutionary roots of inter-individual variation in aggression.

AB - Rapid clearance of nanoagents is a critical criterion for their clinical translation. Herein, it is reported that biodegradable and renal clearable nanoparticles are potentially useful for image-guided photothermal therapy of tumors. The multifunctional nanoparticles with excellent colloidal stability are synthesized through coordination reactions between Fe3+ ions and gallic acid (GA)/polyvinyl pyrrolidone (PVP) in aqueous solution. Detailed characterization reveals that the resulting Fe3+ /GA/PVP complex nanoparticles (FGPNs) integrate strong near-infrared absorption with paramagnetism well. As a result, the FGPNs present outstanding performance for photoacoustic imaging and magnetic resonance imaging of tumors, and outstanding photothermal ablation effect for tumor therapy owing to their high photothermal conversion efficiency. More importantly, the pharmacokinetic behaviors of the FGPNs determined through 125 I labeling suggest that the FGPNs are readily degraded in vivo showing a short biological half-life, and the decomposition products are excreted through either renal clearance pathway or bowel elimination pathway via stomach, which highlights the characteristics of the current multifunctional theranostic agent and their potential in clinical translation. PMID- 29194960 TI - Toward Wearable Self-Charging Power Systems: The Integration of Energy-Harvesting and Storage Devices. AB - One major challenge for wearable electronics is that the state-of-the-art batteries are inadequate to provide sufficient energy for long-term operations, leading to inconvenient battery replacement or frequent recharging. Other than the pursuit of high energy density of secondary batteries, an alternative approach recently drawing intensive attention from the research community, is to integrate energy-generation and energy-storage devices into self-charging power systems (SCPSs), so that the scavenged energy can be simultaneously stored for sustainable power supply. This paper reviews recent developments in SCPSs with the integration of various energy-harvesting devices (including piezoelectric nanogenerators, triboelectric nanogenerators, solar cells, and thermoelectric nanogenerators) and energy-storage devices, such as batteries and supercapacitors. SCPSs with multiple energy-harvesting devices are also included. Emphasis is placed on integrated flexible or wearable SCPSs. Remaining challenges and perspectives are also examined to suggest how to bring the appealing SCPSs into practical applications in the near future. PMID- 29194961 TI - Computational simulation of postoperative pulmonary flow distribution in Alagille patients with peripheral pulmonary artery stenosis. AB - BACKGROUND: Up to 90% of individuals with Alagille syndrome have congenital heart diseases. Peripheral pulmonary artery stenosis (PPS), resulting in right ventricular hypertension and pulmonary flow disparity, is one of the most common abnormalities, yet the hemodynamic effects are ill-defined, and optimal patient management and treatment strategies are not well established. The purpose of this pilot study is to use recently refined computational simulation in the setting of multiple surgical strategies, to examine the influence of pulmonary artery reconstruction on hemodynamics in this population. MATERIALS AND METHODS: Based on computed tomography angiography and cardiac catheterization data, preoperative pulmonary artery models were constructed for 4 patients with Alagille syndrome with PPS (all male, age range: 0.6-2.9 years), and flow simulations with deformable walls were performed. Surgeon directed virtual surgery, mimicking the surgical procedure, was then performed to derive postoperative models. Postoperative simulation-derived hemodynamics and blood flow distribution were then compared with the clinical results. RESULTS: Simulations confirmed substantial resistance, resulting from preoperative severe ostial stenoses, and the use of newly developed adaptive outflow boundary conditions led to excellent agreement with in vivo measurements. Relief of PPS decreased pulmonary artery pressures and improved pulmonary flow distribution both in vivo and in silico with good correlation. CONCLUSIONS: Using adaptive outflow boundary conditions, computational simulations can estimate postoperative overall pulmonary flow distribution in patients with Alagille syndrome after pulmonary artery reconstruction. Obstruction relief along with pulmonary artery vasodilation determines postoperative pulmonary flow distribution and newer methods can incorporate these physiologic changes. Evolving blood flow simulations may be useful in surgical or transcatheter planning and in understanding the complex interplay among various obstructions in patients with peripheral pulmonary stenosis. PMID- 29194959 TI - Standardized hybrid living donor hemihepatectomy in adult-to-adult living donor liver transplantation. AB - The aim of this study was to analyze the outcomes of the most updated version and largest group of our standardized hybrid (laparoscopic mobilization and hepatectomy through midline incision) living donor (LD) hemihepatectomy compared with those from a conventional laparotomy in adult-to-adult living donor liver transplantation (LDLT). Of 237 adult-to-adult LDLTs from August 1997 to March 2017, 110 LDs underwent the hybrid procedure. Preoperative and operative factors were analyzed and compared with conventional laparotomy (n = 126). The median duration of laparoscopic usage was 26 minutes in the hybrid group. Although there was improvement in applying this procedure over time from the beginning of the series of cases studied, blood loss and operative duration were still smaller and shorter in the hybrid group. There was no significant difference between the groups in the incidence of postoperative complications greater than or equal to Clavien-Dindo class III. There was no difference in recipient outcome between the groups. Our standardized procedure of hybrid LD hepatectomy is applicable and safe for all types of LD hepatectomies, and it enables the benefit of both the laparoscopic and the open approach in a transplant center without a laparoscopic expert.

AB - Mass cytometry uniquely enables high-dimensional single-cell analysis of complex populations. This recently developed technology is based on inductively coupled time-of-flight mass spectrometry for multiplex proteomic analysis of more than 40 markers per cell. The ability to characterize the transcriptome is critical for the understanding of disease pathophysiology, medical diagnostics, and drug discovery. Current techniques allowing the in situ detection of transcripts in single cells are limited to a small number of simultaneous targets and are generally tedious and labor-intensive. In this report, we present the development of a multiplex method for targeted RNA detection by combining the mass cytometry and RNAscope(r) platforms. This novel assay, called Metal In Situ Hybridization (MISH), includes the hybridization of RNA-specific target probes followed by signal amplification achieved through a cascade of hybridization events, ending with the binding of amplifier-specific detector probes. The detector probes are tagged with isotopically pure metal atoms used for detection by mass cytometry. Proof-of-principle experiments show the simultaneous detection of three mRNA targets in Jurkat cells in suspension cell assay mode. The localization of transcripts was also investigated using the imaging mass cytometry platform in Jurkat and KG-1a cells. In addition, we optimized the antibody staining procedure to allow the co-detection of mRNA and cell surface markers. Our data demonstrate that MISH can be used to complement protein detection by mass cytometry as well as to investigate gene transcription and translation in single cells.

AB - The diazotrophic cyanobacterium, Trichodesmium, is an integral component of the marine nitrogen cycle and contributes significant amounts of new nitrogen to oligotrophic, tropical/subtropical ocean surface waters. Trichodesmium forms macroscopic, fusiform (tufts), spherical (puffs) and raft-like colonies that provide a pseudobenthic habitat for a host of other organisms including marine invertebrates, microeukaryotes and numerous other microbes. The diversity and activity of denitrifying bacteria found in association with the colonies was interrogated using a series of molecular-based methodologies targeting the gene encoding the terminal step in the denitrification pathway, nitrous oxide reductase (nosZ). Trichodesmium spp. sampled from geographically isolated ocean provinces (the Atlantic Ocean, the Red Sea and the Indian Ocean) were shown to harbor highly similar, taxonomically related communities of denitrifiers whose members are affiliated with the Roseobacter clade within the Rhodobacteraceae (Alphaproteobacteria). These organisms were actively expressing nosZ in samples taken from the mid-Atlantic Ocean and Red Sea implying that Trichodesmium colonies are potential sites of nitrous oxide consumption and perhaps earlier steps in the denitrification pathway also. It is proposed that coupled nitrification of newly fixed N is the most likely source of nitrogen oxides supporting nitrous oxide cycling within Trichodesmium colonies. PMID- 29194964 TI - The bridge between transplantation and regenerative medicine: Beginning a new Banff classification of tissue engineering pathology. AB - The science of regenerative medicine is arguably older than transplantation-the first major textbook was published in 1901-and a major regenerative medicine meeting took place in 1988, three years before the first Banff transplant pathology meeting. However, the subject of regenerative medicine/tissue engineering pathology has never received focused attention. Defining and classifying tissue engineering pathology is long overdue. In the next decades, the field of transplantation will enlarge at least tenfold, through a hybrid of tissue engineering combined with existing approaches to lessening the organ shortage. Gradually, transplantation pathologists will become tissue-(re-) engineering pathologists with enhanced skill sets to address concerns involving the use of bioengineered organs. We outline ways of categorizing abnormalities in tissue-engineered organs through traditional light microscopy or other modalities including biomarkers. We propose creating a new Banff classification of tissue engineering pathology to standardize and assess de novo bioengineered solid organs transplantable success in vivo. We recommend constructing a framework for a classification of tissue engineering pathology now with interdisciplinary consensus discussions to further develop and finalize the classification at future Banff Transplant Pathology meetings, in collaboration with the human cell atlas project. A possible nosology of pathologic abnormalities in tissue engineered organs is suggested.

AB - Tungsten oxide (WO3 ) is an emerging 2D nanomaterial possessing unique physicochemical properties extending a wide spectrum of novel applications which are limited due to lack of efficient synthesis of high-quality WO3 . Here, a facile new synthetic method of forming WO3 from tungsten sulfide, WS2 is reported. Spectroscopic, microscopic, and X-ray studies indicate formation of flower like aggregated nanosized WO3 plates of highly crystalline cubic phase via intermediate orthorhombic tungstite, WO3. H2 O phase. The charge storage ability of WO3 is extremely high (508 F g-1 at current density of 1 A g-1 ) at negative potential range compared to tungstite (194 F g-1 at 1 A g-1 ). Moreover, high (97%) capacity retention after 1000 cycles and capacitive charge storage nature of WO3 electrode suggest its supremacy as a negative electrode of supercapacitors. The asymmetric supercapacitor, based on the WO3 as a negative electrode and mildly reduced graphene oxide as a positive electrode, manifests high energy density of 218.3 mWhm-2 at power density 1750 mWm-2 , and exceptionally high power density, 17 500 mW m-2 , with energy density of 121.5 mWh m-2 . Furthermore, the negative differential resistance (NDR) property of both WO3 and WO3 .H2 O are reported for the first time and NDR is explained with density of state approach. PMID- 29194970 TI - Headspace solid-phase microextraction and gas chromatographic analysis of low molecular-weight sulfur volatiles with pulsed flame photometric detection and quantification by a stable isotope dilution assay. AB - Low-molecular-weight volatile sulfur compounds such as thiols, sulfides, disulfides as well as thioacetates cause a sulfidic off-flavor in wines even at low concentration levels. The proposed analytical method for quantification of these compounds in wine is based on headspace solid-phase microextraction, followed by gas chromatographic analysis with sulfur-specific detection using a pulsed flame photometric detector. Robust quantification was achieved via a stable isotope dilution assay using commercial and synthesized deuterated isotopic standards. The necessary chromatographic separation of analytes and isotopic standards benefits from the inverse isotope effect realized on an apolar polydimethylsiloxane stationary phase of increased film thickness. Interferences with sulfur-specific detection in wine caused by sulfur dioxide were minimized by addition of propanal. The method provides adequate validation data, with good repeatability and limits of detection and quantification. It suits the requirements of wine quality management, allowing the control of oenological treatments to counteract an eventual formation of excessively high concentration of such malodorous compounds. PMID- 29194969 TI - Sex-based disparities in delisting for being "too sick" for liver transplantation. AB - Women with cirrhosis awaiting liver transplantation (LT) experience higher rates of waitlist mortality than men; it is unknown whether practices surrounding delisting for being "too sick" for LT contribute to this disparity beyond death alone. We conducted an analysis of patients listed for LT in the United Network for Organ Sharing/Organ Procurement and Transplantation Network not receiving exception points from May 1, 2007 to July 1, 2014 with a primary outcome of delisting with removal codes of "too sick" or "medically unsuitable." A total of 44 388 patients were included; 4458 were delisted for being "too sick" for LT. Delisting was more frequent in women (11% vs 9%, P < .001). Compared to delisted men, delisted women differed in age (58 vs 57), non-hepatitis C virus listing diagnoses (69% vs 56%), hepatic encephalopathy (36% vs 31%), height (161.9 vs 177.0 cm), private insurance (47% vs 52%), and Karnofsky performance status (60 vs 70) (P < .001 for all). There were no differences in Model for End-Stage Liver Disease including serum sodium and Child Pugh Scores. A competing risk analysis demonstrated that female sex was independently associated with a 10% (confidence interval 2%-18%) higher risk of delisting when accounting for rates of death and transplantation and adjusting for confounders. This study demonstrates a significant disparity in delisting practices by sex, highlighting the need for better assessments of sickness, particularly in women.

AB - BACKGROUND: The diamondback moth Plutella xylostella (L.) is the most widely distributed pest of cruciferous crops and has developed resistance to most commonly used insecticides, including chlorantraniliprole. Resistance to chlorantraniliprole is likely caused by mutations of the target, the ryanodine receptor, and/or mediated by an increase in detoxification enzyme activities. Although target-site resistance is documented in detail, resistance mediated by increased metabolism has rarely been reported. RESULTS: The activity of cytochrome P450 was significantly higher in two resistant P. xylostella populations than in a susceptible one. Among ten detected cytochrome P450 genes, CYP6BG1 was significantly overexpressed (over 80-fold) in a field-resistant population compared with expression in a susceptible one. Knockdown of CYP6BG1 by RNA interference dramatically reduced the 7-ethoxycoumarin-O-deethylase (7-ECOD) activity of P450 by 45.5% and increased the toxicity of chlorantraniliprole toward P. xylostella by 26.8% at 48 h postinjection of double-stranded RNA. By contrast, overexpression of CYP6BG1 in a transgenic Drosophila melanogaster line significantly decreased the toxicity of the insecticide to the transgenic flies. CONCLUSIONS: Overexpression of CYP6BG1 may contribute to chlorantraniliprole resistance in P. xylostella. Our findings will provide new insights into the mechanisms of resistance to diamide insecticides in other insect pests. (c) 2017 Society of Chemical Industry.

AB - Inflammation within areas of interstitial fibrosis and tubular atrophy (i-IFTA) is associated with adverse outcomes in kidney transplantation. We evaluated i IFTA in 429 indication- and 2052 protocol-driven biopsy samples from a longitudinal cohort of 362 kidney-pancreas recipients to determine its prevalence, time course, and relationships with T cell-mediated rejection (TCMR), immunosuppression, and outcome. Sequential histology demonstrated that i-IFTA was preceded by cellular interstitial inflammation and followed by IF/TA. The prevalence and intensity of i-IFTA increased with developing chronic fibrosis and correlated with inflammation, tubulitis, and immunosuppression era (P < .001). Tacrolimus era-based immunosuppression was associated with reduced histologic inflammation in unscarred and scarred i-IFTA compartments, ameliorated progression of IF, and increased conversion to inactive IF/TA (compared with cyclosporine era, P < .001). Prior acute (including borderline) TCMR and subclinical TCMR were followed by greater 1-year i-IFTA, remaining predictive by multivariate analysis and independent of humoral markers. One-year i-IFTA was associated with accelerated IF/TA, arterial fibrointimal hyperplasia, and chronic glomerulopathy and with reduced renal function (P < .001 versus no i-IFTA). In summary, i-IFTA is the histologic consequence of active T cell-mediated alloimmunity, representing the interface between inflammation and tubular injury with fibrotic healing. Uncontrolled i-IFTA is associated with adverse structural and functional outcomes. PMID- 29194972 TI - A composite noninvasive index correlates with liver fibrosis scores in post Fontan patients: Preliminary findings. AB - OBJECTIVE: We hypothesized that clinic-based, hepatic-ultrasound, elastography measurements, either alone or in combination with other noninvasive variables, might correlate with liver-biopsy fibrosis scores in patients post-Fontan. METHODS: Between March 2012 and February 2017, we identified patients post-Fontan that underwent elective cardiac catheterization and simultaneous transvenous hepatic biopsy. From this group, we selected patients that met inclusion criteria for liver-ultrasound, shear-wave elastography. Utilizing the results of elastography, laboratory testing, and time post-Fontan, we constructed a composite Fontan hepatic index as a sum of elastography measurements in kilopascals, model for end-stage liver disease excluding INR scores, and the square root of the number of years post-Fontan. Further, we analyzed correlations between Fontan hepatic index values and fibrosis scores from hepatic biopsy. RESULTS: We identified a total of 79 post-Fontan patients that underwent cardiac catheterization and liver biopsy. Of the 79 patients, 53 met inclusion criteria, and 32 consented to undergo hepatic-ultrasound elastography. Of the 32 that underwent elastography, data from 30 patients was used for analysis. We found no statistically significant differences in demographics, laboratory values, or cardiac catheterization data between the 30 included patients and the 21 that did not participate. Utilizing data from the 30 included patients, we found a strong, highly statistically significant correlation between the Fontan hepatic index values and total fibrosis scores (R = 0.8, P < .00001). However, the cohort size prevented reliable discriminating cut-off values for the range of total fibrosis scores. CONCLUSIONS: In a small cohort of patients post-Fontan, preliminary findings suggest that the composite Fontan hepatic index might be a clinically useful, noninvasive method of serially monitoring for hepatic fibrosis. Further studies, with large patient cohorts, are necessary to validate our findings and develop clinically useful discriminatory cutoff values. PMID- 29194973 TI - Perovskite Quantum Dots and Their Application in Light-Emitting Diodes. AB - Perovskite quantum dots (PQDs) attract significant interest in recent years because of their unique optical properties, such as tunable wavelength, narrow emission, and high photoluminescence quantum efficiency (PLQY). Recent studies report new types of formamidinium (FA) PbBr3 PQDs, PQDs with organic-inorganic mixed cations, divalent cation doped colloidal CsPb1-x Mx Br3 PQDs (M = Sn2+ , Cd2+ , Zn2+ , Mn2+ ) featuring partial cation exchange, and heterovalent cation doped into PQDs (Bi3+ ). These PQD analogs open new possibilities for optoelectronic devices. For commercial applications in lighting and backlight displays, stability of PQDs requires further improvement to prevent their degradation by temperature, oxygen, moisture, and light. Oxygen and moisture facilitated ion migration may easily etch unstable PQDs. Easy ion migration may result in crystal growth, which lowers PLQY of PQDs. Surface coating and treatment are important procedures for overcoming such factors. In this study, new types of PQDs and a strategy of improving their stabilities are introduced. Finally, this paper discusses future applications of PQDs in light-emitting diodes. PMID- 29194975 TI - Biofilm recruitment under nanofiltration conditions: the influence of resident biofilm structural parameters on planktonic cell invasion. AB - It is now generally accepted that biofouling is inevitable in pressure-driven membrane processes for water purification. A large number of published articles describe the development of novel membranes in an effort to address biofouling in such systems. It is reasonable to assume that such membranes, even those with antimicrobial properties, when applied in industrial-scale systems will experience some degree of biofouling. In such a scenario, an understanding of the fate of planktonic cells, such as those entering with the feed water, has important implications with respect to contact killing particularly for membranes with antimicrobial properties. This study thus sought to investigate the fate of planktonic cells in a model nanofiltration biofouling system. Here, the interaction between auto-fluorescent Pseudomonas putida planktonic cells and 7 day-old Pseudomonas fluorescens resident biofilms was studied under permeate flux conditions in a nanofiltration cross flow system. We demonstrate that biofilm cell recruitment during nanofiltration is affected by distinctive biofilm structural parameters such as biofilm depth.

AB - A facile and scalable method using coffee waste grounds as a hard template has been developed to fabricate nanostructured Co3 O4 for the oxygen evolution reaction (OER). Co3 O4 incorporating metals with different valences (M/Co=1:4; M=Cu, Ni, Fe, Cr, and W) were also prepared with similar sheet-like structures comprising nanosized crystallites. After detailed characterization by X-ray diffraction, electron microscopy, and nitrogen sorption, the oxides were employed as OER electrocatalysts. Substitution of octahedral and tetrahedral sites of the spinel structure with divalent and trivalent transition metals (Cu, Ni, Fe, and Cr) increased the activity of Co3 O4 for the OER, whereas incorporation of hexavalent W led to formation of a second crystal phase and significantly higher electrocatalytic performance. Furthermore, this method is easily scaled up for mass production of Co3 O4 with the same nanostructure, which is highly desirable for large-scale application. PMID- 29194974 TI - Serum fetuin-B is positively associated with intrahepatic triglyceride content and increases the risk of insulin resistance in obese Chinese adults: A cross sectional study. AB - BACKGROUND: Fetuin-B impairs insulin action in myotubes and hepatocytes and causes glucose intolerance in mice. This study explored the correlation between serum fetuin-B and intrahepatic triglyceride (IHTG) content, and the association between fetuin-B and the risk of insulin resistance in the general adult population. METHODS: A cross-sectional study of 1318 obese adults who underwent serum fetuin-B testing and hepatic ultrasonography was conducted in Xiamen, China. The IHTG content was determined in 428 subjects by magnetic resonance spectroscopy. RESULTS: Non-alcoholic fatty liver disease prevalence was significantly higher in those with the highest serum fetuin-B concentrations and the highest IHTC content (Tertile 3) than in subjects in Tertiles 1 and 2 (62.6% vs 60.7% and 54.3%, respectively [P = 0.032], and 15.3% vs 12.8% and 12.7%, respectively [P = 0.049]). There was a significant association between increasing serum fetuin-B tertiles and both increasing fasting insulin concentrations (mean [+/- SD] 11.9 +/- 6.8, 12.7 +/- 7.6, and 13.3 +/- 6.4 mIU/L in Tertiles 1, 2 and 3, respectively; P = 0.006) and prevalence of insulin resistance (54.4%, 58.9%, and 64.5% in Tertiles 1, 2 and 3, respectively; P = 0.010). In linear regression analysis, IHTG content was independently and positively correlated with serum fetuin-B (regression coefficient 0.015; P = 0.045). With adjustment for potential confounders, serum fetuin-B was independently associated with increased risk of insulin resistance, with an adjusted odds ratio per standard deviation increase in fetuin-B of 1.14 (95% confidence interval 1.01-1.30; P = 0.031). CONCLUSIONS: The results demonstrate the role of fetuin-B linking liver fat accumulation to insulin resistance in humans. PMID- 29194978 TI - A Novel Regulatory Mechanism for Differentiation of Mesenchymal Stem Cell: Redox State of DJ-1 Matters. AB - Reactive oxygen species (ROS) are multifunctional gas transmitters with diverse biological actions (adverse vs beneficial) dependent on their level. The differentiation of vascular stem cells into smooth muscle cells (SMCs) might be involved in the pathogenesis of cardiovascular disorders including hypertension and atherosclerosis. Therefore, controlling the differentiation of vascular stem cells is a potential strategy for the treatment of vascular diseases. Nonetheless, it remains to be revealed whether ROS could mediate the differentiation of mesenchymal stem cells (MSCs) into SMCs. In addition, there are no redox (reduction-oxidation)-sensitive molecules identified, which are responsible for the ROS-induced differentiation of MSCs. In article number 1700208, Baek et al. [Proteomics 2017, 17, Issue 21] found that ROS mediate the differentiation of MSCs into SMCs through the modification of redox states of a multifunctional ROS-responsive protein, DJ-1, revealing a novel regulatory mechanism for differentiation of MSCs into SMCs and shedding light into the future development of stem-cell-targeted pharmacotherapy. PMID- 29194980 TI - Polar solar panels: Arctic and Antarctic microbiomes display similar taxonomic profiles. AB - Solar panels located on high (Arctic and Antarctic) latitudes combine the harshness of the climate with that of the solar exposure. We report here that these polar solar panels are inhabited by similar microbial communities in taxonomic terms, dominated by Hymenobacter spp., Sphingomonas spp. and Ascomycota. Our results suggest that solar panels, even on high latitudes, can shape a microbial ecosystem adapted to irradiation and desiccation. PMID- 29194982 TI - Synthesis of Monofunctionalized Silsesquioxanes (RSiMe2 O)(iBu)7 Si8 O12 via Alkene Hydrosilylation. AB - The research presented in this work comprehensively describes hydrosilylation of a wide spectrum of alkenes which contain one or more reactive groups with (HSiMe2 O)(iBu)7 Si8 O12 , in the presence of different types of catalysts. Special attention is paid to the influence of alkene, catalyst, and reaction conditions on process effectiveness and selectivity by the precise monitoring of the experiments with in situ FTIR and NMR spectroscopies. More than twenty silsesquioxanes bearing reactive groups (OH, Br, NR2 , CO, COOR, NCO, epoxy, SiR3 ) commonly used in organic and polymer chemistry, were obtained, isolated and characterized by 1 H, 13 C, 29 Si NMR and MALDI TOF. Importantly, in the presented syntheses, commercially available reagents and catalysts were used, meaning that the presented methods could be easily repeated, rapidly scaled up, and widely applied. PMID- 29194981 TI - ddrage: A data set generator to evaluate ddRADseq analysis software. AB - High-throughput sequencing makes it possible to evaluate thousands of genetic markers across genomes and populations. Reduced-representation sequencing approaches, like double-digest restriction site-associated DNA sequencing (ddRADseq), are frequently applied to screen for genetic variation. In particular in nonmodel organisms where whole-genome sequencing is not yet feasible, ddRADseq has become popular as it allows genomewide assessment of variation patterns even in the absence of other genomic resources. However, while many tools are available for the analysis of ddRADseq data, few options exist to simulate ddRADseq data in order to evaluate the accuracy of downstream tools. The available tools either focus on the optimization of ddRAD experiment design or do not provide the information necessary for a detailed evaluation of different ddRAD analysis tools. For this task, a ground truth, that is, the underlying information of all effects in the data set, is required. Therefore, we here present ddrage, the ddRAD Data Set Generator, that allows both developers and users to evaluate their ddRAD analysis software. ddrage allows the user to adjust many parameters such as coverage and rates of mutations, sequencing errors or allelic dropouts, in order to generate a realistic simulated ddRADseq data set for given experimental scenarios and organisms. The simulated reads can be easily processed with available analysis software such as stacks or pyrad and evaluated against the underlying parameters used to generate the data to gauge the impact of different parameter values used during downstream data processing. PMID- 29194984 TI - A gene encoding a DUF523 domain protein is involved in the conversion of 2 thiouracil into uracil. AB - Modified nucleotides are present in many RNA species in all Domains of Life. While the biosynthetic pathways of such nucleotides are well studied, much less is known about the degradation of RNAs and the return to the metabolism of modified nucleotides, their respective nucleosides or heterocyclic bases. Using an E. coli uracil auxotroph, we screened the metagenomic libraries for genes, which would allow the conversion of 2-thiouracil to uracil and thereby lead to the growth on a defined synthetic medium. We show that a gene encoding a protein consisting of previously uncharacterized Domain of Unknown Function 523 (DUF523) is responsible for such phenotype. We have purified this recombinant protein and demonstrated that it contains a Fe?S cluster. The substitution of cysteines, which have been predicted to form such clusters, with alanines abolished the growth phenotype. We conclude that DUF523 is involved in the conversion of 2 thiouracil into uracil in vivo. PMID- 29194979 TI - Synthesis, adenosine receptor binding and molecular modelling studies of novel thieno[2,3-d]pyrimidine derivatives. AB - A series of new molecules containing a thieno[2,3-d]pyrimidine scaffold was synthesized and characterized by adopting an efficient synthetic scheme. The effect of a free or substituted amino group at 2-position as well as an oxo group, imidazole or 1,2,4-triazole ring at 4-position of the scaffold on the affinity and selectivity towards adenosine receptors (ARs) was evaluated. Compounds 17-19 with a free amino group at 2-position along with the presence of an imidazole/1,2,4-triazole ring at 4-position of the scaffold showed selective binding affinities for hA2A AR, whereas carbamoylation of the amino group at 2 position (in the presence of an oxo-group at 4-position of the scaffold) increased the affinity and selectivity of certain compounds (7-10) for hA3 AR. Molecular dynamic simulation study of one of the most active compound 8 (Ki hA1 > 30 MUm, hA2A = 0.65 MUm, and hA3 = 0.124 MUm) revealed the role of important amino acid residues for imparting good affinity towards hA3 and hA2A ARs. Molecular docking studies were carried out for other compounds using the crystal structure of hA2A AR and a homology model of hA3 AR to rationalize their structure-activity relationships. The molecular docking results were in agreement with the experimental binding affinity data of ARs. PMID- 29194983 TI - Translational Development of Microbiome-Based Therapeutics: Kinetics of E. coli Nissle and Engineered Strains in Humans and Nonhuman Primates. AB - Understanding the pharmacology of microbiome-based therapeutics is required to support the development of new medicines. Strains of E. coli Nissle (EcN) were genetically modified and administered to cynomolgus monkeys at doses of 1 * 109 and 1 * 1012 colony-forming units (CFU)/day for 28 days. A clinical study to evaluate the exposure and clearance of EcN in healthy volunteers was also performed. Healthy subjects received oral doses of EcN, 2.5 to 25 * 109 CFU 3 times daily for 28 days or a single day. In cynomolgus monkeys, replicating strains yielded higher fecal concentrations than nonreplicating strains and persisted for longer following cessation of dosing. In the clinical study, all subjects cleared EcN following cessation of dosing with median clearance of 1 week. Quantitative methodology can be applied to microbiome-based therapeutics, and similar kinetics and clearance were observed for EcN in cynomolgus monkeys and humans. PMID- 29194987 TI - Coexistence of poribacterial phylotypes among geographically widespread and phylogenetically divergent sponge hosts. AB - Marine sponges are benthic 'filter-feeding' invertebrates that can host dense and diverse bacterial, archaeal and eukaryotic communities. Due to the finding of several genes encoding symbiosis factors, such as adhesins, ankyrin repeats and tetratricopeptide repeats, the candidate phylum 'Poribacteria' is considered as a promising model microorganism for studying the origin of host-symbiont interactions in sponges. However, relatively little is known about its global diversity and phylogenetic distribution among different sponge hosts. Therefore, in this study we investigated phylogenetic relationships among poribacterial phylotypes and generated a phylogenetic network to examine the distribution and intraspecific diversity of the phylotypes between phylogenetically divergent host sponges at a global scale. For this study 361 poribacterial 16S rRNA gene sequences obtained by Sanger sequencing from 15 different countries and 8 marine regions were gathered. We could demonstrate that the candidate phylum 'Poribacteria' is composed of diverse phylotypes, which are distributed among a wide range of phylogenetically divergent sponge hosts. The current phylogenetic analyses found neither conclusive evidence for co-speciation with its hosts, nor biogeographical correlation. Moreover, we identified a novel poribacterial clade, which might represent a link between the previously established four 'Poribacteria' clades.

PMID- 29194985 TI - A multiplex reverse transcription PCR and automated electronic microarray assay for detection and differentiation of seven viruses affecting swine. AB - Microarray technology can be useful for pathogen detection as it allows simultaneous interrogation of the presence or absence of a large number of genetic signatures. However, most microarray assays are labour-intensive and time consuming to perform. This study describes the development and initial evaluation of a multiplex reverse transcription (RT)-PCR and novel accompanying automated electronic microarray assay for simultaneous detection and differentiation of seven important viruses that affect swine (foot-and-mouth disease virus [FMDV], swine vesicular disease virus [SVDV], vesicular exanthema of swine virus [VESV], African swine fever virus [ASFV], classical swine fever virus [CSFV], porcine respiratory and reproductive syndrome virus [PRRSV] and porcine circovirus type 2 [PCV2]). The novel electronic microarray assay utilizes a single, user-friendly instrument that integrates and automates capture probe printing, hybridization, washing and reporting on a disposable electronic microarray cartridge with 400 features. This assay accurately detected and identified a total of 68 isolates of the seven targeted virus species including 23 samples of FMDV, representing all seven serotypes, and 10 CSFV strains, representing all three genotypes. The assay successfully detected viruses in clinical samples from the field, experimentally infected animals (as early as 1 day post-infection (dpi) for FMDV and SVDV, 4 dpi for ASFV, 5 dpi for CSFV), as well as in biological material that were spiked with target viruses. The limit of detection was 10 copies/MUl for ASFV, PCV2 and PRRSV, 100 copies/MUl for SVDV, CSFV, VESV and 1,000 copies/MUl for FMDV. The electronic microarray component had reduced analytical sensitivity for several of the target viruses when compared with the multiplex RT-PCR. The integration of capture probe printing allows custom onsite array printing as needed, while electrophoretically driven hybridization generates results faster than conventional microarrays that rely on passive hybridization. With further refinement, this novel, rapid, highly automated microarray technology has potential applications in multipathogen surveillance of livestock diseases. PMID- 29194986 TI - Alga-Made Anti-Hepatitis B Antibody Binds to Human Fcgamma Receptors. AB - Microalgae are unicellular eukaryotic organisms which represent an emerging alternative to other cell biofactories commonly used to produce monoclonal antibodies. Microalgae display several biotechnological advantages such as their rapid growth rate and their phototrophic lifestyle allowing low production costs as protein expression is solar-fueled. Recently, a fully assembled recombinant IgG antibody directed against Hepatitis B surface antigen is produced and secreted in the culture medium of the diatom Phaeodactylum tricornutum. A biochemical characterization of this recombinant antibody demonstrated that the Asn-297 is N-glycosylated by oligomannosides. In the immune system, antibodies interact with effector molecules and cells through their Fc part and the recognition of Fcgamma receptors (FcgammaR) which are important for inducing phagocytosis of opsonized microbes. Interactions between IgG and FcgammaR are influenced by the N-glycan structures present on the Asn-297. In this study, the authors characterized the binding capacity of the anti-hepatitis B recombinant IgG produced in P. tricornutum to two human Fcgamma receptors (FcgammaRI and IIIa) using a cellular binding assay and surface plasmon resonance (SPR). This allowed us to demonstrate that the alga-made antibody is able to bind FcgammaRI with a reduced affinity and engages FcyRIIIa with 3-times higher affinity compared to a control human IgG1.

AB - The aim of this study was to investigate the effects of castration and testosterone supplementation on nitroso-redox status, cardiac metabolism markers, and S100 proteins expression in the heart of male rats. 50 male Wistar rats were randomized into five groups with ten animals each: group 1: control intact (CON); group 2: sham operated (Sh-O); group 3: sesame oil-treated rats (S-oil); group 4: gonadoectomized (GDX); and group 5: gonadoectomized rats treated with testosterone (GDX-T) for 8 weeks. Our results showed myofibrillar weaving, apoptosis, inflammation, and fibrosis (as reflected by increased activity of MMP 9 and MMP 2) in the heart of gonadoectomized rats. Testosterone supplementation restored the normal structure of the heart. In addition, a state of nitroso-redox imbalance was observed in the heart of castrated rats with increased NO (425.1 +/ 322.8 vs. 208 +/- 67.06, p ? 0.05) and MDA (33.18 +/- 9.45 vs. 22.04 +/- 7.13, p ? 0.05) and decreased GSH levels (0.71 +/- 0.13 vs. 1.09 +/- 0.19, p = 0.001). Testosterone treatment leads to a re-establish of only NO levels (425.1 +/- 322.8 vs. 210.4 +/- 114.3, p > 0.05). Markers of cardiac metabolism showed an enhancement of LDH activity (12725 +/- 4604 vs. 5381 +/- 3122, p ? 0.05) in the heart of castrated rats. This was inversed by testosterone replacement (12725 +/- 4604 vs. 5781 +/- 5187, p ? 0.05). Furthermore, castration induced heart's accumulation of triglycerides (37.24 +/- 6.17 vs. 27.88 +/- 6.47, p ? 0.05) and total cholesterol (61.44 +/- 3.59 vs. 54.11 +/- 7.55, p ? 0.05), which were significantly reduced by testosterone supplementation (29.03 +/- 2.47 vs. 37.24 +/- 6.17, p ? 0.05) and (47.9 +/- 4.15 vs. 61.44 +/- 3.59, p ? 0.001). Cardiomyocytes of castrated rats showed a decreased immunoexpression of S100 proteins compared to control animals. A restoration of S100 proteins immunostaining in cardiomyocyte cytoplasm was observed after testosterone supplementation. These findings confirm the deleterious effects of testosterone deficiency on cardiac function and highlight the involvement of nitric oxide, metalloproteinases 2 and 9, and S100 proteins.

AB - The design of small and high-affinity lectin inhibitors remains a major challenge because the natural ligand binding sites of lectin are often shallow and have polar character. Herein we report that derivatizing galactose with un-natural structural elements that form multiple non-natural lectin-ligand interactions (orthogonal multipolar fluorine-amide, phenyl-arginine, sulfur-pi, and halogen bond) can provide inhibitors with extraordinary affinity (low nanomolar) for the model lectin, galectin-3, which is more than five orders of magnitude higher than the parent galactose; moreover, is selective over other galectins. PMID- 29194991 TI - Haemorrhage following transoral robotic surgery. AB - BACKGROUND: To report our experience of postoperative haemorrhage in patients following transoral robotic surgery (TORS). METHODS: Data were collected on patients having TORS. Postoperative haemorrhage within 30 days was graded using the Mayo Clinic grading system. RESULTS: Transoral robotic surgery operations were performed on 122 patients. There were 23 bleeding events classified as minor to severe following 19 operations (16%). Haemorrhage requiring a return to the operating room occurred after 7 operations (6%). The odds of an emergent haemorrhage were 5.19 times greater in patients who had a staged neck dissection after TORS (P = .05). The odds of a postoperative bleeding event were 2.6 times greater in patients receiving a larger resection (P = .107). There were no haemorrhage events in the 36 patients who received a synchronous neck dissection with transcervical ligation of the external carotid artery. CONCLUSIONS: Surgical intervention for TORS haemorrhage occurred in 6% patients. No haemorrhage occurred in patients who had ligation of the external carotid artery.

PMID- 29194997 TI - Piecing together cis-regulatory networks: insights from epigenomics studies in plants. AB - 5-Methylcytosine, a chemical modification of DNA, is a covalent modification found in the genomes of both plants and animals. Epigenetic inheritance of phenotypes mediated by DNA methylation is well established in plants. Most of the known mechanisms of establishing, maintaining and modifying DNA methylation have been worked out in the reference plant Arabidopsis thaliana. Major functions of DNA methylation in plants include regulation of gene expression and silencing of transposable elements (TEs) and repetitive sequences, both of which have parallels in mammalian biology, involve interaction with the transcriptional machinery, and may have profound effects on the regulatory networks in the cell. Methylome and transcriptome dynamics have been investigated in development and environmental responses in Arabidopsis and agriculturally and ecologically important plants, revealing the interdependent relationship among genomic context, methylation patterns, and expression of TE and protein coding genes. Analyses of methylome variation among plant natural populations and species have begun to quantify the extent of genetic control of methylome variation vs. true epimutation, and model the evolutionary forces driving methylome evolution in both short and long time scales. The ability of DNA methylation to positively or negatively modulate binding affinity of transcription factors (TFs) provides a natural link from genome sequence and methylation changes to transcription. Technologies that allow systematic determination of methylation sensitivities of TFs, in native genomic and methylation context without confounding factors such as histone modifications, will provide baseline datasets for building cell-type- and individual-specific regulatory networks that underlie the establishment and inheritance of complex traits.

PMID- 29194995 TI - The dynamic metabolomic changes throughout mouse epididymal lumen fluid potentially contribute to sperm maturation. AB - Epididymal lumen fluids are directly responsible for sperm maturation. However, very little is known about the molecular details of small molecule metabolites in the epididymal lumen fluids until now. Here we identified and compared the metabolic profiles of mouse caput and cauda epididymal lumen fluids using GC-MS technique. Among 236 metabolites identified in caput and cauda epididymis, 36 were significantly enriched in caput epididymis while 18 were significantly enriched in cauda epididymis. Pathway analysis identified ascorbate and aldarate metabolism and beta-alanine metabolism as most relevant pathways in caput and cauda epididymis, respectively. Ascorbate, dehydroascorbic acid and beta-alanine associated with these two pathways were firstly reported in mouse epididymal lumen fluids and might play important roles in sperm maturation. PMID- 29194996 TI - Effects of pioglitazone treatment on blood leptin levels in patients with type 2 diabetes. AB - AIMS/INTRODUCTION: The aim of the present study was to carry out a meta-analysis of randomized controlled trials (RCTs) that investigated the effects of pioglitazone on blood leptin levels in patients with type 2 diabetes. MATERIALS AND METHODS: Literature searches were carried out using Medline, the Cochrane Controlled Trials Registry and ClinicalTrials.gov, and RCTs that investigated the effects of pioglitazone on blood leptin levels in patients with type 2 diabetes were selected. Standardized mean differences and 95% confidence intervals were calculated. RESULTS: A total of 10 RCTs met the eligibility criteria and were included in the meta-analysis. Significantly lower blood leptin levels were observed in the pioglitazone group (standardized mean difference -0.58, 95% confidence interval -1.12 to -0.05%, P = 0.03) than in the placebo group. There was no significant difference in blood leptin levels observed between the pioglitazone and oral antidiabetic drug groups (standardized mean difference 0.01, 95% confidence interval -0.20 to 0.19%, P = 0.93). CONCLUSIONS: There was a significant difference in blood leptin levels between the pioglitazone and placebo groups. However, relatively few RCTs were included in the study, and there was a high level of statistical heterogeneity; we believe that this could have affected the results. PMID- 29194994 TI - The inner-rod component of Shigella flexneri type 3 secretion system, MxiI, is involved in the transmission of the secretion activation signal by its interaction with MxiC. AB - The virulence of Shigella mainly resides in the use of a Type 3 Secretion System (T3SS) to inject several proteins inside the host cell. Three categories of proteins are hierarchically secreted: (1) the needle components (MxiH and MxiI), (2) the translocator proteins which form a pore (translocon) inside the host cell membrane, and (3) the effectors interfering with the host cell signaling pathways. In the absence of host cell contact, the T3SS is maintained in an "off" state by the presence of a tip complex. We have previously identified a gatekeeper protein, MxiC, which sequesters effectors inside the bacteria probably by interacting with MxiI, the inner-rod component. Upon cell contact and translocon insertion, a signal is most likely transmitted from the top of the needle to the base, passing through the needle and allowing effectors release. However, the molecular mechanism underlying the transmission of the activation signal through the needle is still poorly understood. In this work, we investigate the role of MxiI in the activation of the T3SS by performing a mutational study. Interestingly we have shown that mutations of a single residue in MxiI (T82) induce an mxiC-like phenotype and prevent the interaction with MxiC. Moreover, we have shown that the L26A mutation significantly reduces T3 secretion. The L26A mutation impairs the interaction between MxiI and Spa40, a keystone component of the switch between needle assembly and translocators secretion. The L26A mutation also sequesters MxiC. All these results highlight the crucial role of MxiI in regulating the secretion and transmitting the activation signal of the T3SS.

AB - With about 70 million cases of infertility worldwide, half of which are caused by male factors, sperm analysis is critical to determine male fertility potential. Conventional semen analysis methods involve complex and manual inspection with a microscope, and these methods are labor intensive and can take several days. Due to unavailability of rapid, convenient, and user-friendly semen analysis tools, many men do not seek medical evaluation, especially in resource-constrained settings. Furthermore, as conventional methods have to be conducted in the laboratories, many men are unwilling to be tested as a result of social stigma in certain regions of the world. One solution can be found in at-home sperm analysis, which allows men to test their semen without the hassle of going to and paying for a clinic. Herein, we examine current at-home sperm analysis technologies and compare them to the traditional laboratory-based methods. In addition, we discuss emerging sperm analysis approaches and describe their limitations and future directions. PMID- 29194999 TI - Computational Screening of Doped alpha-MnO2 Catalysts for the Oxygen Evolution Reaction. AB - Minimizing energy and materials costs for driving the oxygen evolution reaction (OER) is paramount for the commercialization of water electrolysis cells and rechargeable metal-air batteries. Structural stability, catalytic activity, and electronic conductivity of pure and doped alpha-MnO2 for the OER are studied using density functional theory calculations. As model surfaces, we investigate the (110) and (100) facets, on which three possible active sites are identified: a coordination unsaturated, a bridge, and a bulk site. For pure and Cr-, Fe-, Co , Ni-, Cu-, Zn-, Cd-, Mg-, Al-, Ga-, In-, Sc-, Ru-, Rh-, Ir-, Pd-, Pt-, Ti-, Zr-, Nb-, and Sn-doped alpha-MnO2 , the preferred valence at each site is imposed by adding/subtracting electron donors (hydrogen atoms) and electron acceptors (hydroxy groups). From a subset of stable dopants, Pd-doped alpha-MnO2 is identified as the best catalyst and the only material that can outperform pristine alpha-MnO2 . Different approaches to increase the bulk electron conductivity of semiconducting alpha-MnO2 are discussed. PMID- 29195001 TI - Foot Barriers in Patients With Early Rheumatoid Arthritis: An Interview Study Among Swedish Women and Men. AB - OBJECTIVE: Foot impairments are related to reduced mobility and participation restrictions in daily activities in patients with established rheumatoid arthritis (RA). The new biologic medications are effective and reduce disease activity, but not disability to the same extent. Foot impairments are assumed to be related to participation restrictions also in patients with early RA, diagnosed after the introduction of biologic medications. Knowledge of foot impairments needs to be explored further after the introduction of biologic disease-modifying antirheumatic drugs (bDMARDs). The aim of this study was to explore the patients' perspective of foot impairments related to early RA. METHODS: The sample included 59 patients (ages 20-63 years) who were interviewed about participation dilemmas in daily life using the critical incident technique. The interviews were audio-recorded and transcribed. Data related to foot impairments were extracted and analyzed thematically. A research partner validated the analysis. RESULTS: Patients with early RA described a variety of participation restrictions related to foot impairments: foot hindrances in domestic life, foot impairments influencing work, leisure activities restricted by one's feet, struggling to be mobile, and foot impairments as an early sign of rheumatic disease. CONCLUSION: There is a need to focus on foot impairments related to early RA, and for health care professionals to understand these signs. A suggestion for future research is to conduct a longitudinal followup of foot impairment related to medication, disease activity, and disability in patients diagnosed after the introduction of bDMARDs. PMID- 29195000 TI - Internal Ophthalmic Arteries Within the Brain-Base Arterial System in Guinea Pig. AB - In situ vascular specimens of the arterial circle were collected from 15 adult guinea pigs, both male and female. After specimen preparation, the vessels were filled with synthetic latex and subjected to analysis. Similar as in the case of other rodents, vertebral arteries were merged into basilar artery, further dividing into two short terminal branches. Distally, the terminal branches extend into caudal cerebral arteries. Rostral part of the arterial circle of brain is supplied with blood from maxillary arteries via external and internal ophthalmic arteries connected by a short anastomosis. This type of vascularity may probably be considered a functional analogy to the internal carotid arteries observed in other species. Rostral and caudal parts of the arterial circle of brain are connected by exceptionally long caudal communicating arteries. In author's opinion, the disputable contribution of internal carotid artery and the exceptional contribution of internal ophthalmic arteries in the cerebral blood supply in guinea pigs as compared to other rodents, warrants further research on the subject.

AB - Pediatric cardiologists teach complicated concepts to a diverse group of learners that include medical students, nurses, residents, fellows, patients, and parents. Unfortunately, much of what is taught is not retained. In order to increase the likelihood of long-term retention, a cardiologist should teach with both meaning and sense. The authors provide a review of these concepts and give specific examples of how to teach in ways that both make sense and are meaningful to a cardiologist's leaners. PMID- 29195002 TI - Validation of Classification Criteria of Macrophage Activation Syndrome in Japanese Patients With Systemic Juvenile Idiopathic Arthritis. AB - OBJECTIVE: To validate whether the 2016 American College of Rheumatology/European League Against Rheumatism classification criteria of macrophage activation syndrome (MAS) complicating systemic juvenile idiopathic arthritis (JIA) is practical in the real world. METHODS: A combination of expert consensus and analysis of real patient data was conducted by a panel of 15 pediatric rheumatologists. A total of 65 profiles comprised 18 patients with systemic JIA associated MAS and 47 patients with active systemic JIA without evidence of MAS. From these profiles, 10 patient data points for full-blown MAS, 11 patient data points for MAS onset, and 47 patient data points for acute systemic JIA without MAS were evaluated. RESULTS: Evaluation of the classification criteria to discriminate full-blown MAS from acute systemic JIA without MAS showed a sensitivity of 1.000 and specificity of 1.000 at the time of full-blown MAS. Sensitivity was 0.636 and specificity was 1.000 at the time of MAS onset. The number of measurement items that fulfilled the criteria increased in full-blown MAS compared to that at MAS onset. At MAS onset, the positive rates of patients who met the criteria for platelet counts and triglycerides were low, whereas those for aspartate aminotransferase were relatively high. At full-blown MAS, the number of patients who met the criteria for each measurement item increased. CONCLUSION: The classification criteria for MAS complicating systemic JIA had a very high diagnostic performance. However, the diagnostic sensitivity for MAS onset was relatively low. For the early diagnosis of MAS in systemic JIA, the dynamics of laboratory values during the course of MAS should be further investigated. PMID- 29195004 TI - Optimized fluorescent proteins for the rhizosphere-associated bacterium Bacillus mycoides with endophytic and biocontrol agent potential. AB - Tracking of fluorescent protein (FP)-labelled rhizobacteria is a key prerequisite to gain insights into plant-bacteria interaction mechanisms. However, the performance of FPs mostly has to be optimized for the bacterial host and for the environment of intended application. We report on the construction of mutational libraries of the superfolder green fluorescent protein sfGFP and the red fluorescent protein mKate2 in the bacterium B. mycoides, which next to its potential as plant-biocontrol agent occasionally enters an endophytic lifestyle. By fluorescence-activated cell sorting and comparison of signal intensities at the colony and single-cell level, the variants sfGFP(SPS6) and mKate (KPS12) with significantly increased brightness were isolated. Their high applicability for plant-bacteria interaction studies was shown by confocal laser scanning microscopy tracking of FP-tagged B. mycoides strains after inoculation to Chinese cabbage plants in a hydroponic system. During the process of colonization, strain EC18 rapidly attached to plant roots and formed a multicellular matrix, especially at the branching regions of the root hair, which probably constitute entrance sites to establish an endophytic lifestyle. The universal applicability of the novels FPs was proven by expression from a weak promoter, dual-labelling of B. mycoides, and by excellent expression and detectability in additional soil- and rhizosphere-associated Bacillus species.

PMID- 29195005 TI - Synthetic Indolactam V Analogues as Inhibitors of PAR2-Induced Calcium Mobilization in Triple-Negative Breast Cancer Cells. AB - Human proteinase-activated receptor 2 (PAR2), a transmembrane G-protein-coupled receptor (GPCR), is an attractive target for a novel anticancer therapy, as it plays a critical role in cell migration and invasion. Selective PAR2 inhibitors therefore have potential as anti-metastatic drugs. Knowing that the natural product teleocidin A2 is able to inhibit PAR2 in tumor cells, the goal of the present study was to elaborate structure-activity relationships and to identify potent PAR2 inhibitors with lower activity against the adverse target, protein kinase C (PKC). For this purpose, an efficient gram-scale total synthesis of indolactam V (i.e., the parent structure of all teleocidins) was developed, and a library of derivatives was prepared. Some compounds were indeed found to exhibit high potency as PAR2 inhibitors at low nanomolar concentrations with improved selectivity (relative to teleocidin A2). The pseudopeptidic fragment bridging the C3 and C4 positions of the indole core proved to be essential for target binding, whereas activity and target selectivity depends on the substituents at N1 or C7. This study revealed novel derivatives that show high efficacy in PAR2 antagonism combined with increased selectivity. PMID- 29195009 TI - Ontogeny of Surface Texture of Limb Bones in Modern Aquatic Birds and Applicability of Textural Ageing. AB - Despite its importance in various disciplines, a general method to assess ontogenetic ages of skeletal and fossil specimens has been lacking for birds. Although the textural ageing method was formulated to assess relative ontogenetic ages of specimens from inspection of bone surface textures, the exact correspondence of surface textures to ontogenetic stages has not yet been clear. In this study, bone surface textures of six major limb bones (humerus, ulna, carpometacarpus, femur, tibiotarsus, and tarsometatarsus) were described in postnatal ontogenies of four species of modern birds (Calonectris leucomelas, Phalacrocorax capillatus, Larus crassirostris, and Cerorhinca monocerata) from 14 to 28 individuals of known ontogenetic stages for each species. Consistently with the previous postulation, it was found that bones of chicks were characterized by rough surface textures with numerous grooves/depressions that host minute foramina. Bones of fledglings/juveniles, which are generally as large as those of adults but more slender, were characterized by the occasional presence of depressions and foramina. Histological observations confirmed that these rough surface textures were underlain by fibrolamellar bone tissue which is associated with active periosteal ossification. These results indicate that the smooth surface texture in adults is formed after the cessation of circumferential bone growth, which probably takes place between fledging and the attainment of sexual maturity. The available evidence suggests that the textural ageing is probably applicable to the entire Neognathae, a clade containing most crown-group birds. Anat Rec, 301:1026-1045, 2018.

AB - beta-Thalassemia is an inherited hematologic disorder caused by various mutations of the beta-globin gene, thus resulting in a significant decrease in adult hemoglobin (HbA) production. An increase in fetal hemoglobin (HbF) levels by drug molecules is considered of great potential in beta-thalassemia treatment and is expected to counterbalance the impaired production of HbA. In this work, based on a set of 129 experimentally tested biological inhibitors, we developed and validated a computational model for the prediction of K562 functional inhibition, possibly associated with HbF induction. To facilitate future advancements in the field, we incorporated our model into Enalos Cloud Platform, which enabled online access to our computational scheme (http://enalos.insilicotox.com/K562) through a user-friendly interface. This web service is offered to the wider community to promote in silico drug discovery through fast and reliable predictions. PMID- 29195010 TI - A Library of Multipurpose Supramolecular Supergelators: Fabrication of Structured Silica, Porous Plastics, and Fluorescent Gels. AB - Supramolecular gels find applications in various fields. Usually, a specific gelator is useful only for a specific application. This one-gelator-one application format is one factor that limits the usefulness of supramolecular gels. We report the synthesis of a library of gelators from a common core by using a click-chemistry approach. Thus, the click reaction of beta-azido-4,6-O benzylidene-galactopyranoside (1) with various alkynes gave 11 different gelators having varying gelation abilities. Whereas gelators having alkyl-chain substituents congealed alkanes and tetraethylorthosilicate (TEOS), the gelators having aromatic substituents congealed aromatic solvents. We exploited this difference in gelling behavior in the templated synthesis of silica rods and porous plastics. The styrene gel of gelator 2 j was polymerized, and the gelator was removed by washing to obtain porous polystyrene. The TEOS gel of gelator 2 b was polymerized to silica, and the gelator template was removed by calcination to give microstructured silica rods. We also developed fluorescent gelator 2 f by this method, which might find applications by virtue of its fluorescence in the assembled state. PMID- 29195011 TI - Experiences With Telehealth Followup in Patients With Rheumatoid Arthritis: A Qualitative Interview Study. AB - OBJECTIVE: To explore the experiences of a patient-reported outcome (PRO)-based telehealth followup from the perspective of patients with rheumatoid arthritis (RA) and their experiences of increasing their active role, and responsibility for disease control in particular. METHODS: Adopting a strategy of interpretive description, we conducted individual, semistructured interviews with 15 RA patients participating in a telehealth followup. Participants were selected purposively and consecutively from both sexes and with various ages, disease durations, and disease severity. The analysis was inductive, with a constant comparative approach. First, we identified the main themes conveying the participants' experiences. Then we constructed patient typologies to explain different perspectives on the telehealth followup. RESULTS: Five themes covered the participants' experiences: a flexible solution, responsibility, knowledge of RA, communication and involvement, and continuity. Two typologies, the keen patient and the reluctant patient, represented opposite perspectives and preferences regarding the core value of and approach to the telehealth followup. CONCLUSION: The participants had positive perceptions of the PRO-based telehealth followup and saw it as a flexible and resource-saving solution. They reported disadvantages related to missing face-to-face contact with health professionals. The 2 typologies, the keen and the reluctant patient, help us understand the patients' different needs, wishes, and abilities to take part in telehealth followup. Our findings reveal a need for more insight into how telehealth followup could be integrated in routine clinical practice, paying special attention to how reluctant patients may be supported. PMID- 29195015 TI - Does using testicular sperm retrieval rather than ejaculated spermatozoa improve reproductive outcomes in couples with previous ART failure and poor ovarian response? A case-controlled study. AB - The objective of this study was to assess whether testicular-retrieved spermatozoa improve reproductive outcomes compared to fresh ejaculate in women with poor ovarian response and a history of previous ART failure. The study was performed as a retrospective case-control study at a university-based reproductive center in Montreal, Quebec, Canada. Eighteen poor-responder patients were matched 3 : 1 with 54 controls. Poor responders were defined as those with <=3 oocytes retrieved at oocyte pickup. Cases were identified as poor responders, and only those with previous IVF failure(s) as an indication for testicular retrieved spermatozoa were included. Controls were age and cycle attempt number matched. All patients were included only once. From January 1, 2009 to December 31, 2015, all patients and controls underwent an IVF cycle using ICSI with either testicular spermatozoa or ejaculated spermatozoa, respectively. Outcomes included live birth rate, pregnancy rate, miscarriage rate, oocyte number, and embryo transfer (ET) day. The results showed live birth rates, pregnancy rates, and miscarriage rates were similar. There were fewer day 2 ETs (8.5% vs. 48.6%, p = 0.01) and more day 5 blastocyst transfers (25.0% vs. 5.4%, p = 0.05) in the testicular sperm retrieval group compared to controls and thus an overall suggestion of better embryo quality in the testicular sperm group. Overall, however, the use of testicular sperm retrieval appears to add little. Women with poor ovarian response typically have a poor prognosis with respect to live birth rates, and this is further supported in this study. The suggestion of better embryo quality in the testicular-retrieved sperm group would need to be further assessed in a larger multicentered study. PMID- 29195012 TI - The association between varicocoeles and vascular disease: an analysis of U.S. claims data. AB - S?tudies have suggested an association between varicocele, hypogonadism, and elevated oxidative stress markers, but no other health risks have been associated with varicoceles. ????We sought to determine the association between varicocele and incident medical comorbidities. ?????????????????????????????????????????????Using the Truven Health MarketScan(r) claims database from 2001 to 2009, we identified 4459 men with varicoceles, and 100,066 controls based on ICD-9 and CPT codes, with an average follow-up of 3.1 person years. Men with varicoceles were classified as symptomatic or asymptomatic based on co-existing diagnoses. Men with medical comorbidities present before or within 1 year of index diagnosis were excluded. Metabolic and cardiovascular outcome variables were identified via ICD-9 codes. A Cox regression analysis was used to assess incident risk of metabolic and cardiovascular disease amongst the different groups. Men with varicoceles had a higher incidence of heart disease compared to men who underwent infertility testing (HR 1.22, 95% CI: 1.03-1.45), and men who underwent vasectomy (HR 1.32, 95% CI 1.13-1.54). The varicoceles group also had a higher risk of diabetes (HR 1.73, 95% CI: 1.37-2.18) and hyperlipidemia (HR 1.15, 95% CI: 1.03-1.28) compared to the vasectomy group. Furthermore, men with symptomatic varicoceles (n = 3442) had a higher risk of heart disease, diabetes, and hyperlipidemia following diagnosis, while men with asymptomatic varicoceles (n = 1017) did not. Given the prevalence of varicoceles, further research is needed to understand the implications of a varicocele to a man's overall health. PMID- 29195018 TI - Dendron-Grafted Polylysine-Based Dual-Modal Nanoprobe for Ultra-Early Diagnosis of Pancreatic Precancerosis via Targeting a Urokinase-Type Plasminogen Activator Receptor. AB - Pancreatic ductal adenocarcinoma (PDAC) is one of the leading causes of cancer death. Early detection of precancerous pancreatic intraepithelial neoplasia (PanIN) tissues is an urgent challenge to improve the PDAC prognosis. Here, a urokinase-type plasminogen activator receptor (uPAR)-targeted magnetic resonance (MR)/near-infrared fluorescence (NIRF) dual-modal nanoprobe dendron-grafted polylysine (DGL)-U11 for ultra-early detection of pancreatic precancerosis is reported. Because of its good biocompatibility and biodegradability, globular architecture, and well-defined reactive groups, the DGL is chosen as the platform to load with a pancreatic tumor-targeting peptide U11, a magnetic resonance contrast agent Gd3+ -diethylene triamine pentaacetic acid, and a near-infrared fluorescent cyanine dye Cy5.5. The nanoprobe DGL-U11 has several preferable characteristics, such as active peptide targeting to activator receptor, good biocompatibility, dual-modal imaging diagnosis, and well controlled diameter in a range of 15-25 nm. Upon incorporation of the active U11 peptide target to the overexpressed activator receptor uPAR, the targeted nanoprobe DGL-U11 can increase to the earlier PanIN-II stage through in vivo NIRF imaging. Labeled with both MR and NIRF bioimaging reporters, the uPAR-targeted dual-modal nanoprobe is very effective in the targeted imaging of precancerous PanINs and PDAC lesions with high sensitivity and spatial resolution, providing a promising platform to the ultra-early detection of PDAC. PMID- 29195014 TI - Long-term penile morphometric alterations in patients treated with robot-assisted versus open radical prostatectomy. AB - Neglected side effects after radical prostatectomy have been previously reported. In this context, the prevalence of penile morphometric alterations has never been assessed in robot-assisted radical prostatectomy series. We aimed to assess prevalence of and predictors of penile morphometric alterations (i.e. penile shortening or penile morphometric deformation) at long-term follow-up in patients submitted to either robot-assisted (robot-assisted radical prostatectomy) or open radical prostatectomy. Sexually active patients after either robot-assisted radical prostatectomy or open radical prostatectomy prospectively completed a 28 item questionnaire, with sensitive issues regarding sexual function, namely orgasmic functioning, climacturia and changes in morphometric characteristics of the penis. Only patients with a post-operative follow-up >= 24 months were included. Patients submitted to either adjuvant or salvage therapies or those who refused to comprehensively complete the questionnaire were excluded from the analyses. A propensity-score matching analysis was implemented to control for baseline differences between groups. Logistic regression models tested potential predictors of penile morphometric alterations at long-term post-operative follow up. Overall, 67 (50%) and 67 (50%) patients were included after open radical prostatectomy or robot-assisted radical prostatectomy, respectively. Self-rated post-operative penile shortening and penile morphometric deformation were reported by 75 (56%) and 29 (22.8%) patients, respectively. Rates of penile shortening and penile morphometric deformation were not different after open radical prostatectomy and robot-assisted radical prostatectomy [all p > 0.5]. At univariable analysis, self-reported penile morphometric alterations (either penile shortening or penile morphometric deformation) were significantly associated with baseline international index of erectile function-erectile function scores, body mass index, post-operative erectile function recovery, year of surgery and type of surgery (all p < 0.05). At multivariable analysis, robot assisted radical prostatectomy was independently associated with a lower risk of post-operative penile morphometric alterations (OR: 0.38; 95% CI: 0.16-0.93). Self-perceived penile morphometric alterations were reported in one of two patients after radical prostatectomy at long-term follow-up, with open surgery associated with a potential higher risk of this self-perception. PMID- 29195016 TI - Association of high cost sharing and targeted therapy initiation among elderly Medicare patients with metastatic renal cell carcinoma. AB - High out-of-pocket costs may limit access to oral therapies covered by patients' prescription drug benefits. We explored financial barriers to treatment initiation in patients newly diagnosed with metastatic renal cell carcinoma (mRCC) by comparing Medicare Part D patients with low out-of-pocket costs due to receipt of full low-income subsidies (LIS beneficiaries) to their counterparts who were responsible for more than 25% cost sharing during Medicare's initial coverage phase (non-LIS beneficiaries). We used 2011-2013 100% Medicare claims for non-LIS and LIS beneficiaries newly diagnosed with metastases in the liver, lung, or bone to examine targeted therapy treatment initiation rates and time to initiation for (1) oral medications (sorafenib, sunitinib, everolimus, pazopanib, or axitinib) covered under Medicare's prescription drug benefit (Part D); (2) injected or infused medications (temsirolimus or bevacizumab) covered by Medicare's medical benefit (Part B); and (3) any (Part D or Part B) targeted therapy. The final sample included 1721 patients. On average, non-LIS patients were responsible for out-of-pocket costs of >=$2,800 for their initial oral prescription, as compared to <=$6.60 for LIS patients. Compared to LIS patients, a lower percentage of non-LIS patients initiated oral therapies (risk-adjusted rates, 20.7% vs. 33.9%; odds ratio [OR] = 0.49, 95% CI: 0.36-0.67, P < 0.001) and any targeted therapies (26.7% vs. 40.4%, OR = 0.52, 95% CI: 0.38-0.71, P < 0.001). Non-LIS patients were also slower to access therapy. High cost sharing was associated with reduced and/or delayed access to targeted therapies under Medicare Part D, suggesting that financial barriers play a role in treatment decisions. PMID- 29195019 TI - Is immunosuppression, induced by neonatal thymectomy, compatible with poor reproductive performance in adult male rats? AB - With increasing knowledge that the immune system has a major impact on reproductive health, the potential for cells arising in organs such as the thymus to alleviate oxidative stress has been revealed. This study addresses the impact of neonatal thymectomy on male reproductive function in pubertal and adult animals. Neonatal Sprague Dawley rats were allotted to four treatments consisting of fully thymectomized, partially thymectomized, intact, and sham-operated rats. Half of the rats in each treatment were sacrificed at 40 and the other half at 80 days of age. Testicular volume, ventral prostate and spleen weight, several sperm attributes (concentration, motility, livability, membrane integrity, sperm penetration into mucus, total antioxidant capacity, mitochondrial dehydrogenase activity), plasma superoxide dismutase, glutathione, and testosterone level as well as fertility decreased in thymectomized rats. Adrenal gland weight, sperm malondialdehyde level, indices of oxidative stress, sperm abnormality, testicular and sperm lipid peroxidation, protein carbonylation, and sperm reactive oxygen species generation increased in thymectomized rats. In thymectomized rats, the testes contained high levels of malondialdehyde but low levels of glutathione and ferric-reducing antioxidant power. Epididymal sperm reactive oxygen species, blood lipid peroxidation, and oxidative stress indices in blood and spermatozoa were highest in fully thymectomized, intermediate in partially thymectomized, and lowest in both pubertal and mature control rats. Blood levels of superoxide dismutase, lipid peroxidation indices, and testosterone, and mitochondrial adenosine triphosphate and dehydrogenase activities in epididymal spermatozoa were lowest in fully thymectomized, intermediate in partially thymectomized, and highest in both pubertal and mature control rats. The data indicated that increased oxidative stress and mitochondrial dysfunction might play a role in the mechanism of immunosuppression-induced testicular and sperm abnormalities. PMID- 29195017 TI - High Health Care Utilization Preceding Diagnosis of Systemic Lupus Erythematosus in Youth. AB - OBJECTIVE: Childhood-onset systemic lupus erythematosus (SLE) is associated with high risk for organ damage, which may be mitigated by early diagnosis and treatment. We characterized health care utilization for youth in the year preceding SLE diagnosis compared to controls. METHODS: Using Clinformatics DataMart (OptumInsight) de-identified administrative data from 2000 to 2013, we identified 682 youth ages 10-24 years with new-onset SLE (>=3 International Classification of Diseases, Ninth Revision codes for SLE 710.0, each >30 days apart), and 1,364 age- and sex-matched healthy controls. We compared the incidence of ambulatory, emergency, and inpatient visits 12 months before SLE diagnosis and frequency of primary diagnoses. We examined subject characteristics associated with utilization preceding SLE diagnosis. RESULTS: Youth with SLE had significantly more visits in the year preceding diagnosis than controls across ambulatory (incidence rate ratio [IRR] 2.48, P < 0.001), emergency (IRR 3.42, P < 0.001), and inpatient settings (IRR 3.02, P < 0.001). The most frequent acute care diagnoses and median days to SLE diagnosis were: venous thromboembolism (313, interquartile range [IQR] 18-356), thrombocytopenia (278, IQR 39-354), chest pain (73, IQR 29.5-168), fever (52, IQR 17-166), and acute kidney failure (14, IQR 5-168). Having a psychiatric diagnosis prior to SLE diagnosis was strongly associated with increased utilization across all settings. CONCLUSION: Youth with SLE have high health care utilization throughout the year preceding SLE diagnosis. Examining variable diagnostic trajectories of youth requiring acute care preceding SLE diagnosis, and increased attention to psychiatric morbidity, may help improve care for youth with new-onset SLE. PMID- 29195013 TI - Effect of bacterial growth rate on bacteriophage population growth rate. AB - It is important to understand how physiological state of the host influence propagation of bacteriophages (phages), due to the potential higher phage production needs in the future. In our study, we tried to elucidate the effect of bacterial growth rate on adsorption constant (delta), latent period (L), burst size (b), and bacteriophage population growth rate (lambda). As a model system, a well-studied phage T4 and Escherichia coli K-12 as a host was used. Bacteria were grown in a continuous culture operating at dilution rates in the range between 0.06 and 0.98 hr-1 . It was found that the burst size increases linearly from 8 PFU.cell-1 to 89 PFU.cell-1 with increase in bacteria growth rate. On the other hand, adsorption constant and latent period were both decreasing from 2.6?10-9 ml.min-1 and 80 min to reach limiting values of 0.5 * 10-9 ml.min-1 and 27 min at higher growth rates, respectively. Both trends were mathematically described with Michaelis-Menten based type of equation and reasons for such form are discussed. By applying selected equations, a mathematical equation for prediction of bacteriophage population growth rate as a function of dilution rate was derived, reaching values around 8 hr-1 at highest dilution rate. Interestingly, almost identical description can be obtained using much simpler Monod type equation and possible reasons for this finding are discussed.

AB - Structured macroporous hydrogels that have controllable porosities on both the nanoscale and the microscale offer both the swelling and interfacial properties of bulk hydrogels as well as the transport properties of "hard" macroporous materials. While a variety of techniques such as solvent casting, freeze drying, gas foaming, and phase separation have been developed to fabricate structured macroporous hydrogels, the typically weak mechanics and isotropic pore structures achieved as well as the required use of solvent/additives in the preparation process all limit the potential applications of these materials, particularly in biomedical contexts. This review highlights recent developments in the field of structured macroporous hydrogels aiming to increase network strength, create anisotropy and directionality within the networks, and utilize solvent-free or additive-free fabrication methods. Such functional materials are well suited for not only biomedical applications like tissue engineering and drug delivery but also selective filtration, environmental sorption, and the physical templating of secondary networks.

AB - Forster resonance energy transfer (FRET) is used here for the first time to monitor the in vivo fate of nanoparticles made of the squalene-gemcitabine prodrug and two novel derivatives of squalene with the cyanine dyes 5.5 and 7.5, which behave as efficient FRET pair in the NIR region. Following intravenous administration, nanoparticles initially accumulate in the liver, then they show loss of their integrity within 2 h and clearance of the squalene bioconjugates is observed within 24 h. Such awareness is a key prerequisite before introduction into clinical settings. PMID- 29195021 TI - Association Between Marginal Jawbone Loss and Onset of Rheumatoid Arthritis and Relationship to Plasma Levels of RANKL. AB - OBJECTIVE: To investigate whether periodontitis, characterized by marginal jawbone loss, precedes the onset of symptoms of rheumatoid arthritis (RA), and to analyze plasma levels of RANKL (a cytokine that is crucial for bone resorption) and anti-citrullinated peptide antibodies (ACPAs) in presymptomatic individuals compared with matched referent controls. METHODS: Marginal jawbone loss was measured on dental radiographs of the premolar/molar regions in the jaws in 176 subjects, 93 of whom subsequently developed RA. Among these participating subjects, 46 had documented radiographs predating symptom onset, and 45 cases could be matched to controls, according to sex, age, and smoking status. Plasma RANKL concentrations were analyzed using enzyme-linked immunosorbent assay. A receiver operating characteristic curve was used to define the cutoff value for RANKL positivity. RESULTS: Bone loss was significantly greater in presymptomatic subjects classified as never smokers compared with that in controls, and increasing levels of bone loss were associated with a higher risk of the subsequent development of RA (hazard ratio 1.03, 95% confidence interval 1.01 1.05). No association between jawbone loss and RA was observed in smokers. A significantly greater extent of marginal jawbone loss was detected in RANKL positive presymptomatic subjects, and even more pronounced jawbone loss was observed in those who were positive for both RANKL and ACPA. CONCLUSION: Marginal jawbone loss preceded the clinical onset of RA symptoms, but this was observed only in nonsmokers. Moreover, marginal jawbone loss was significantly greater in RANKL-positive presymptomatic subjects compared with RANKL-negative presymptomatic subjects and was highest in presymptomatic subjects positive for both ACPA and RANKL. PMID- 29195025 TI - Lack of additional effects of long-term, low-dose clarithromycin combined treatment compared with topical steroids alone for chronic rhinosinusitis in China: a randomized, controlled trial. AB - BACKGROUND: In China, clarithromycin is considered an effective treatment option for chronic rhinosinusitis (CRS) due to its unique immunopathologic characteristics. Our study's aim was to determine whether a topical steroid and clarithromycin combination is better than a single topical steroid for Chinese patients with CRS. METHODS: Patients with CRS with/without nasal polyps were included in this study and randomly assigned to a clarithromycin plus budesonide aqua nasal spray group (CLM + BUD, clarithromycin 0.25 g/d and budesonide 256 MUg/d) or a budesonide-alone group (BUD, budesonide 256 MUg/d). The treatment period was 3 months. The primary outcome was visual analog scale (VAS) score for 5 major symptoms and a general nasal symptom. Other assessments included the 22 item Sino-Nasal Outcome Test (SNOT-22), computed tomography scan (Lund-Mackay score), and rigid nasal endoscopy (Lund-Kennedy score). Nasal secretion evaluation was the secondary outcome. RESULTS: Seventy-four patients were included and randomly assigned to the CLM + BUD group (n = 38) or the BUD group (n = 36). VAS scores for nasal obstruction, rhinorrhea, smell reduction, headache, nasal pain, and general nasal symptom were markedly improved in both treatment arms, but the differences between groups were not significant. Furthermore, SNOT-22, Lund-Mackay, and Lund-Kennedy scores improved significantly after treatment in both groups, and were slightly better in the CLM + BUD group. For the responders in the CLM + BUD group, interleukin (IL)-6 and IL-8 were markedly reduced. CONCLUSION: The combination of CLM + BUD for the treatment of first-time-diagnosed CRS in this Chinese population cohort did not show a better effect compared with a single BUD regimen, but it may have a better effect in some patients with increased IL-6 or IL-8. PMID- 29195027 TI - Harnessing the Maltodextrin Transport Mechanism for Targeted Bacterial Imaging: Structural Requirements for Improved in vivo Stability in Tracer Design. AB - Diagnosis and localization of bacterial infections remains a significant clinical challenge. Harnessing bacteria-specific metabolic pathways, such as the maltodextrin transport mechanism, may allow specific localization and imaging of small or hidden colonies. This requires that the intrabacterial tracer accumulation provided by the transporter is matched by high serum stability of the tracer molecule. Herein, radiolabeled maltodextrins of varying chain lengths and with free nonreducing/reducing ends are reported and their behavior against starch-degrading enzymes in the blood, which compromise their serum stability, is evaluated. Successful single-photon emission computed tomography (SPECT) imaging is shown in a footpad infection model in vivo by using the newly developed model tracer, [99m Tc]MB1143, and the signal is compared with that of 18 F fluorodeoxyglucose positron emission tomography ([18 F]FDG-PET) as a nonbacterial specific marker for inflammation. Although the [99m Tc]MB1143 imaging signal is highly specific, it is low, most probably due to insufficient serum stability of the tracer. A series of stability tests with different 18 F-labeled maltodextrins finally yielded clear structural guidelines regarding substitution patterns and chain lengths of maltodextrin-based tracers for nuclear imaging of bacterial infections. PMID- 29195026 TI - Effects of the insulin-like growth factor system on testicular differentiation and function: a review of the literature. AB - We recently described the occurrence of cryptorchidism, oligoasthenoteratozoospermia, and genital abnormalities in patients with distal 15q chromosome structural abnormalities. This observation brought us to hypothesize that insulin-like growth factor (IGF) receptor (IGF1R), mapping on the 15q 26.3 chromosomal band, may be involved in testicular function. To further evaluate this topic, we reviewed in vitro and in vivo studies exploring the role of the IGF system [IGF1, IGF2, IGF1R, insulin receptor substrates (IRS)] at the testicular level both in animals and in humans. In animals, IGF1/IGF1R has been found to be involved in testicular development during embryogenesis, in Sertoli cell (SC) proliferation, and in germ cell (GS) proliferation and differentiation. Interestingly, IGF1R seems to mediate follicle-stimulating hormone (FSH) effects through the PI3K/AKT pathway. In humans, IGF1 directly increases testicular volume. The molecular pathways responsible for testicular differentiation and IGF1/IGF1R signaling are highly conserved among species; therefore, the IGF system may be involved in FSH signaling also in humans. We suggest a possible molecular pathway occurring in human SCs, which involves both IGF1 and FSH through the PI3K/AKT pathway. The acknowledgment of an IGF1 mediation of the FSH induced effects may open new ways for a targeted therapy in idiopathic non-FSH responder oligoasthenoteratozoospermia. PMID- 29195031 TI - Surgical correction of Peyronie's disease via tunica albuginea plication: long term follow-up. AB - Peyronie's disease (PD) is an acquired connective tissue disorder of the tunica albuginea with fibrosis and inflammation that lead to palpable plaques formation, penile curvature, and pain during erection. Patients report negative effects on main domains such as physical appearance and self-image, sexual function, and performance. The aim of this study was to evaluate plication of the albuginea outcomes after a long-term follow-up period. Between 1998 and 2006, a total of 204 patients with PD underwent surgical correction with albuginea plication technique. We obtained complete long-term follow-up data in 187 cases. The follow up data included evaluation of curvature correction, penile shortening, sexual function, complications, and patient satisfaction. After a mean follow-up of 141 months, the most common postoperative complications were: loss of length (150 patients had a minimal penile shortening <=1.5 cm, 37 patient between 1.5, and 3 cm, none >3 cm), recurrent or residual penile curvature (15 patients, without impairing sexual intercourse), erectile dysfunction (15 patients had IIEF-5 < 10 at 5 years of follow-up vs. 28 patients at 10 years), change in penile sensation (37 patients experienced paresthesia of the glans 1 year after surgery, 28 at 5 years, and 15 at 10 years); painful or palpable suture knots (in 20 cases) spontaneously healed in 3 months. Overall, 77% of the patients and partners were completely satisfied, 14% partially satisfied, and 9% unsatisfied. Plication procedure is safe and simple to be performed compared with the classical Nesbit's procedure. It has a shorter surgical time, lower costs, and could be successfully performed by less experienced surgeons too. It has a minimal risk of de novo erectile dysfunction, injury to the dorsal neurovascular bundle. Results are good in terms of patient satisfaction according to anatomical outcome and functional correction. PMID- 29195030 TI - Accuracy of birth certificate head circumference measurements: Massachusetts, 2012-2013. AB - BACKGROUND: Zika virus has recently emerged as a novel cause of microcephaly. CDC has asked states to rapidly ascertain and report cases of Zika-linked birth defects, including microcephaly. Massachusetts added head circumference to its birth certificate (BC) in 2011. The accuracy of head circumference measurements from state vital records data has not been reported. METHODS: We sought to assess the accuracy of Massachusetts BC head circumference measurements by comparing them to measurements for 2,217 infants born during 2012-2013 captured in the Massachusetts Birth Defects Monitoring Program (BDMP) data system. BDMP contains information abstracted directly from infant medical records and served as the true head circumference value (i.e., gold standard) for analysis. We calculated the proportion of head circumference measurements in agreement between the BC and BDMP data. We assigned growth chart head circumference percentile categories to each BC and BDMP measurement, and calculated the sensitivity and specificity of BC-based categories to predict BDMP-based categories. RESULTS: No difference was found in head circumference measurements between the two sources in 77.9% (n = 1,727) of study infants. The sensitivity of BC-based head circumference percentile categories ranged from 85.6% (<3rd percentile) to 92.7% (>=90th percentile) and the specificity ranged from 97.6% (>=90th percentile) to 99.3% (<3rd percentile). CONCLUSIONS: BC head circumference measurements agreed with those abstracted from the medical chart the majority of the time. Head circumference measurements on the BC were more specific than sensitive across all standardized growth chart percentile categories.

PMID- 29195033 TI - Total prevention of folic acid-preventable spina bifida and anencephaly would reduce child mortality in India: Implications in achieving Target 3.2 of the Sustainable Development Goals. AB - BACKGROUND: The potential to reduce child mortality by preventing folic acid preventable spina bifida and anencephaly (FAP SBA) is inadequately appreciated. To quantify possible reduction in FAP SBA-associated child mortality in low- and middle-income countries, we conducted an analysis to demonstrate in India, a country with more than 25 million births and 1.2 million under-five deaths each year, the decrease in neonatal, infant, and under-five mortality that would occur through total prevention of FAP SBA. METHODS: We estimated the percent reductions in neonatal, infant, and under-five mortality that would have occurred in India in 2015 had all of FAP SBA been prevented. We also estimated the contributions of these reductions toward India's Sustainable Development Goals on child mortality indicators. We considered the overall prevalence of spina bifida and anencephaly in India as 5 per 1,000 live births, of which 90% were preventable with effective folic acid intervention. RESULTS: In the year 2015, folic acid interventions would have prevented about 116,070 cases of FAP SBA and 101,565 under-five deaths associated with FAP SBA. Prevention of FAP SBA would have reduced annually, neonatal, infant, and under-five mortality by 10.2%, 8.9%, and 8.3%, respectively. These reductions would have contributed 18.5% and 17.2% to the reductions in neonatal and under-five mortality, respectively, needed by India to achieve its 2030 Sustainable Developmental Goal Target 3.2 addressing preventable child mortality. CONCLUSIONS: Total prevention of FAP SBA clearly has a significant potential for immediate reductions in neonatal, infant, and under five mortality in India, and similarly other countries. PMID- 29195024 TI - Tuberculosis Risk in Ankylosing Spondylitis, Other Spondyloarthritis, and Psoriatic Arthritis in Sweden: A Population-Based Cohort Study. AB - OBJECTIVE: Rheumatoid arthritis is a risk factor for tuberculosis (TB), particularly following treatment with biologic agents. Since these therapies are increasingly used in ankylosing spondylitis (AS), other types of spondyloarthritis (SpA), and psoriatic arthritis (PsA), we investigated the corresponding TB risks in these patients. METHODS: We identified individuals with AS/SpA/PsA, and non-AS/SpA/PsA comparators by linking Swedish national patient, population, TB, and rheumatology registers, and followed them for TB occurrence. Incidence rates were estimated for biologic-naive and biologic-exposed patients and the comparators. We calculated hazard ratios (HRs), adjusted for age, sex, and country of birth. RESULTS: Included in this study were 38,702 patients with AS/SpA/PsA, and 200,417 persons from the general population. Among the patients, 11 active TB cases were identified, with an incidence rate (per 105 ) of 22 (95% confidence interval [95% CI] 8.3-59.2) for biologic-exposed patients, 2.7 (95% CI 1.3-5.6) for biologic-naive patients, and 2.4 (95% CI 1.8-3.3) for non-AS/SpA/PsA comparators. The adjusted HR comparing biologic-naive patients to the general population was 1.2 (95% CI 0.5-2.7), and 7.5 (95% CI 1.9-29) comparing biologic exposed to biologic-naive patients. CONCLUSION: Biologic-naive AS/SpA/PsA patients are not at an increased TB risk in Sweden. Following treatment with biologic agents, the risk increased, but the absolute TB risk was low. PMID- 29195032 TI - Ultrasensitive NIR-SERRS Probes with Multiplexed Ratiometric Quantification for In Vivo Antibody Leads Validation. AB - Immunotargeting ability of antibodies may show significant difference between in vitro and in vivo. To select antibody leads with high affinity and specificity, it is necessary to perform in vivo validation of antibody candidates following in vitro antibody screening. Herein, a robust in vivo validation of anti-tetraspanin 8 antibody candidates against human colon cancer using ratiometric quantification method is reported. The validation is performed on a single mouse and analyzed by multiplexed surface-enhanced Raman scattering using ultrasensitive and near infrared (NIR)-active surface-enhanced resonance Raman scattering nanoprobes (NIR SERRS dots). The NIR-SERRS dots are composed of NIR-active labels and Au/Ag hollow-shell assembled silica nanospheres. A 93% of NIR-SERRS dots is detectable at a single-particle level and signal intensity is 100-fold stronger than that from nonresonant molecule-labeled spherical Au NPs (80 nm). The result of SERRS based antibody validation is comparable to that of the conventional method using single-photon-emission computed tomography. The NIR-SERRS-based strategy is an alternate validation method which provides cost-effective and accurate multiplexing measurements for antibody-based drug development. PMID- 29195028 TI - Effect of varicocelectomy and/or mast cells stabilizer on sperm DNA fragmentation in infertile patients with varicocele. AB - This study aimed to assess the effect of varicocelectomy and/or mast cells (MCs) stabilizer on sperm DNA fragmentation in infertile men with varicocele (Vx). Overall, 120 infertile patients were randomized to three equal treatment arms; patients that underwent varicocelectomy, patients on 1 mg ketotifen twice daily for three months, and patients that underwent varicocelectomy followed with 1 mg ketotifen twice daily for three months. These patients were subjected to history taking, clinical examination, semen analysis, and estimation of sperm DNA fragmentation index (DFI). After 3 months, all investigated groups showed significant improvement regarding the mean total sperm count, sperm concentration, total sperm motility, and sperm normal forms percentage compared with the pre-treatment data. As well, the mean sperm DFI was significantly improved compared with the pre-treatment data; in men that underwent varicocelectomy (34.6% vs. 28.3%), in men on MC stabilizer only (33.4% vs. 27.8%), and in men that underwent varicocelectomy followed by MC stabilizer (34.3% vs. 25.1%). Sperm DFI improvement percentages showed the highest improvement in men that underwent varicocelectomy followed with MC stabilizer compared with the other two groups (26.8% vs. 18.2%, 16.8%). Sperm DFI improvement percentages showed significant increases in the infertile patients with Vx grade III compared to Vx grade II in all investigated groups. It is concluded that in infertile men associated with Vx and high sperm DFI, surgical repair followed with MCs stabilizer significantly improve sperm DFI compared with either surgical repair or MCs stabilizer alone. PMID- 29195029 TI - Association of MGMT promoter methylation with tumorigenesis features in patients with ovarian cancer: A systematic meta-analysis. AB - BACKGROUND: The MGMT is a key tumor suppressor gene and aberrant promoter methylation has been reported in many cancers. However, the relationship between MGMT promoter methylation and ovarian cancer remains controversial. This meta analysis was first conducted to estimate the clinical significance of MGMT promoter methylation in ovarian carcinoma. METHODS: Literature search was performed in the PubMed, Embase, EBSCO and Cochrane Library databases. The pooled odds ratio (OR) and their corresponding 95% confidence interval (95% CI) were summarized. RESULTS: Final 10 studies with 910 ovarian tissue samples were included in this meta-analysis. MGMT promoter methylation was significantly higher in ovarian cancer than in normal ovarian tissues (OR = 4.13, 95% CI = 2.32 7.33, p < .001). The MGMT had a similar methylation status in cancer versus benign lesions and low malignant potential (LMP) samples (OR = 2.01, 95% CI = 0.67-6.04, p = .212; OR = 1.42, 95% CI = 0.46-4.40, p = .543; respectively). MGMT promoter methylation was correlated with pathological types in which it was significantly lower in serous cancer than in nonserous cancer (OR = 0.29, 95% CI = 0.14-0.59, p = .001). The methylation of the MGMT promoter was not associated with clinical stage and tumor grade (OR = 1.46, 95% CI = 0.71-3.02, p = .301; OR = 1.13, 95% CI = 0.51-2.46, p = .767; respectively). CONCLUSIONS: MGMT promoter methylation may be correlated with the tumorigenesis of ovarian cancer. It was associated with tumor histotypes, but not correlated with clinical stage and tumor grade. More prospective studies with lager sample sizes are necessary in the future. PMID- 29195034 TI - Birth defect survival for Hispanic subgroups. AB - BACKGROUND: Previous studies demonstrate that infant and childhood mortality differ among children with birth defects by maternal race/ethnicity, but limited mortality information is published for Hispanic ethnic subgroups. METHODS: We performed a retrospective cohort study using data for children with birth defects born to Hispanic mothers during 1999-2007 from 12 population-based state birth defects surveillance programs. Deaths were ascertained through multiple sources. Survival probabilities were estimated by the Kaplan-Meier method. Cox proportional hazards regression was used to examine the effect of clinical and demographic factors on mortality risk. RESULTS: Among 28,497 Hispanic infants and children with major birth defects, 1-year survival was highest for infants born to Cuban mothers at 94.6% (95% confidence intervals [CI] 92.7-96.0) and the lowest for Mexicans at 90.2% (95% CI 89.7-90.6; p < .0001). For children aged up to 8 years, survival remained highest for Cuban Americans at 94.1% (95% CI 91.8 95.7) and lowest for Mexican Americans at 89.2% (95% CI 88.7-89.7; p = .0002). In the multivariable analysis using non-Hispanic White as the reference group, only infants and children born to Mexican mothers were noted to have a higher risk of mortality for cardiovascular defects. CONCLUSIONS: This analysis provides a better understanding of survival and mortality for Hispanic infants and children with selected birth defects. The differences found in survival, particularly the highest survival rates for Cuban American children and lowest for Mexican American children with birth defects, underscores the importance of assessing Hispanic ethnic subgroups, as differences among subgroups appear to exist.

AB - Cationic glycopolymers have shown to be excellent candidates for the fabrication of gene delivery devices due to their ability to electrostatically interact with negatively charged nucleic acids and the carbohydrate residues ensure enhanced stability and low toxicity of the polyplexes. The ability to engineer the polymers for optimized compositions, molecular weights, and architectures is critical in the design of effective gene delivery vehicles. Therefore, in this study, the aqueous reversible addition-fragmentation chain transfer polymerization (RAFT) was used to synthesize well-defined cationic glycopolymers with various cationic segments. For the preparation of cationic parts, N-[3 (dimethylamino)propyl]methacrylamide hydrochloride (DMAPMA.HCl), water-soluble methacrylamide monomer containing tertiary amine, was polymerized to produce DMAPMA.HCl homopolymer, which was then used as macroCTA in the block copolymerization with two other methacrylamide monomers containing different pendant groups, namely, 2-aminoethyl methacrylamide hydrochloride (AEMA) (with primary amine) and N-(3-aminopropyl) morpholine methacrylamide (MPMA) (with morpholine ring). In addition, statistical copolymers of DMAPMA.HCl with either AEMA or MPMA were also synthesized. All resulting cationic polymers were utilized as macroCTA for the RAFT copolymerization with 2-lactobionamidoethyl methacrylamide (LAEMA), which consists of the pendent galactose residues to achieve DMAPMA.HCl-based glycopolymers. From the in vitro cytotoxicity study, the cationic glycopolymers showed better cell viabilities than the corresponding cationic homopolymers. Furthermore, complexation of the cationic polymers with siRNA, cellular uptake of the resulting polyplexes, and gene knockdown efficiencies were evaluated. All cationic polymers/glycopolymers demonstrated good complexation ability with siRNA at low weight ratios. Among these cationic polymer-siRNA polyplexes, the polyplexes prepared from the two glycopolymers, P(DMAPMA65-b-LAEMA15) and P[(DMAPMA65-b-MPMA63)-b-LAEMA16], showed outstanding results in the cellular uptake, high EGFR knockdown, and low post-transfection toxicity, suggesting the great potential in siRNA delivery of these novel glycopolymers.

We summarize the state-of-the-art techniques for mathematically modeling cellular stiffness and mechanics and the cytoskeletal components and factors that regulate them. We highlight key experiments that have assisted model parameterization and compare the advantages of different models that have been used to recapitulate these experiments. An overview of feed-forward mechanisms from signaling to cytoskeleton remodeling is provided, followed by a discussion of the rapidly growing niche of encapsulating feedback mechanisms from cytoskeletal and cell mechanics to signaling. We discuss broad areas of advancement that could accelerate research and understanding of cellular mechanobiology. A precise understanding of the molecular mechanisms that affect cell and tissue mechanics and function will underpin innovations in medical device technologies of the future.

AB - Our study provides an integrated analysis of the variability of greenhouse gas (GHG) footprints of field-grown tomatoes for processing. The global farm-specific data set of 890 observations across 14 countries over a three-year period (2013 2015) was obtained from farms grown under Unilever's sustainable agricultural code. It represents on average 3% of the annual global production of processing tomatoes: insights can be used to help inform corporate sourcing strategies and certification schemes. The median GHG footprint ranged from 18 in Chile to 61 kg CO2-equiv per tonne of tomatoes in India, lower than results reported in other studies. We found that footprints are more consistent within countries than between them. Using linear mixed effect models, we quantified the relative influence of environmental conditions and farm management factors. Key variables were area of production and the method of fertilizer application. GHG footprints decreased with increasing area of production to a threshold of 17.4 ha. Farms using single fertilizer application methods in general had a larger GHG footprint than those using a combination of methods. We conclude that farm management factors should be prioritized for future data collection, and more stringent guidance on acceptable practices is required if greater comparability of outcomes is needed either within a scheme, such as the Unilever's sustainable agriculture code, or between schemes. PMID- 29195042 TI - pH Switchable Nanoassembly for Imaging a Broad Range of Malignant Tumors. AB - Polymer-based fluorescent nanomaterials have proven to universally image various tumors based on their extremely sharp responsiveness to pH change. Such a property has never been realized in supramolecular systems. We herein design a small molecule (DPP-thiophene-4) that is composed of a diketopyrrolopyrrole (DPP) core and two alkyl chains terminated with quaternary ammonium. DPP-thiophene-4 can self-assemble into a nonfluorescent nanoassembly when the pH is >7.0 but reversibly disassembles back to fluorescent monomers when the pH is <6.8. Meanwhile, its fluorescence emission increases by 10-fold within a 0.2 pH unit change. Such a fluorogenic nanoassembly can precisely differentiate a number of malignant tumors among normal tissues in vivo due to the slight acidity within tumor microenvironments. Further the nanoassembly shows satisfactory biocompatibility and an effective clearance from the body. Overall, this supramolecular fluorogenic nanoassembly exhibits an immense potential for realizing broad range tumor diagnosis.

AB - The asymmetric ruthenium-catalyzed reductive amination employing ammonia and hydrogen to primary amines is described. Here we demonstrate the capability of our catalyst to perform a chemo- and enantioselective process while using simple ammonia gas as a reagent, one of the most attractive and industrially relevant nitrogen sources. The presence of a catalytic amount of ammonium iodide was essential for obtaining good yields and enantioselectivities. The mechanism of this reaction was investigated by DFT and we found a viable pathway that also explains the trend and magnitude of enantioselectivity through the halide series in good agreement with the experimental data. The in-depth investigation of substrate conformers during the reaction turned out to be crucial in obtaining an accurate prediction of the enantioselectivity. Furthermore, we report the crystallographic data of the chiral [Ru(I)H(CO)((S,S)-f-binaphane)(PPh3)] complex, which we identified as the most efficient catalyst in our investigation. PMID- 29195044 TI - Biomimetic Oxygen-Evolving Photobacteria Based on Amino Acid and Porphyrin Hierarchical Self-Organization. AB - Biomimetic organization provides a promising strategy to develop functional materials and understand biological processes. However, how to mimic complex biological systems using simple biomolecular units remains a great challenge. Herein, we design and fabricate a biomimetic cyanobacteria model based on self integration of small bioinspired molecules, including amphiphilic amino acid, 3,4 dihydroxyphenylalanine (DOPA), and metalloporphyrin and cobalt oxide nanoparticles (Co3O4 NPs), with the assistance of chemical conjugation and molecular self-assembly. The assembled amino acid fiber can be modified by DOPA to form covalently bound DOPA melanin containing hydroxyl and quinone species via Schiff base reaction. The adhering template can further tune the self-assembly of metalloporphyrin and Co3O4 NPs into J-aggregation and dispersive distribution, respectively, mainly via coordination binding. Metalloporphyrin molecules in the resulting hybrid fibers capture light; quinone species accept the excited electrons, and Co3O4 NPs catalyze water oxidation. Thus, the essential components of the photosystem-II protein complex in cyanobacteria are simplified and engineered into a simple framework, still retaining a similar photosynthetic mechanism. In addition, this architecture leads to efficient coupling of antenna, quinone-type reaction center, and photocatalyst, which increases the flux of light energy from antenna to reaction center for charge separation, resulting in enhanced oxygen evolution rate with excellent sustainability. PMID- 29195047 TI - Fluorescence Enhancement of Terminal Amine Assembled on Gold Nanoclusters and Its Application to Ratiometric Lysine Detection. AB - Ratiometric fluorescent sensors have emerged as an attractive tool for analytical sensing and optical imaging due to their providing a built-in self-calibration for environmental effects. However, cumbersome processes of nanoparticles modified with fluorophores for constructing traditional ratiometric sensors limit their further application. Herein, we report a facile and label-free strategy for constructing a ratiometric sensor based on an aggregation-induced-emission (AIE) active amine-terminated small molecule on the surface of gold nanoclusters (AuNCs). Intrinsic fluorescence of the terminal primary amine of the small molecule lysine resulting from AIE was first observed in the presence of glutathione-stabilized gold nanoclusters (GSH-AuNCs). Using lysine as both the fluorophore and the analyte, the synthesized GSH-AuNCs showed a good lysine responsive ratiometric property. The AIE-active dual-emitting fluorescence property of the GSH-AuNCs/lysine complex made it feasible to achieve ratiometrically detection of the analyte without conjugated fluorogen. This AIE active GSH-AuNC-based biosensor possesses high selectivity, rapid response, and excellent photostability. Moreover, the strategy opens a new pathway for the construction of a label-free ratiometric fluorescent sensor with various applications.

For example, the formation of a chemical bond between two iodide anions to form a divalent polyiodide anion is seemingly prohibited due to Coulombic repulsion. Using ab initio molecular dynamics simulations, we show that in the 1-ethyl-3 methylimidazolium (EMIM)/I3 ionic crystal, the reactive formation of divalent and even trivalent polyiodide anions occurs with extremely small energetic barriers, due to the electrostatic field of the ionic lattice. A practical consequence of this anomalous reactivity is that iodide anions are efficiently transported within the crystal through a "Grotthuss-exchange" mechanism involving bond breaking and forming events. We characterize two distinct transport pathways, involving both I42- and I73- intermediates, with fast transport of iodide resulting from the release of an I- anion on the opposite side of the intermediate species from the initial bond formation. The ordered cation arrangement in the crystal provides the necessary electrostatic screening for close approach of anions, suggesting a new counterintuitive approach to obtain high ionic conductivity. This new design principle could be used to develop better solid-state electrolytes for batteries, fuel cells, and supercapacitors. PMID- 29195037 TI - Intrabilayer 64Cu Labeling of Photoactivatable, Doxorubicin-Loaded Stealth Liposomes. AB - Doxorubicin (Dox)-loaded stealth liposomes (similar to those in clinical use) can incorporate small amounts of porphyrin-phospholipid (PoP) to enable chemophototherapy (CPT). PoP is also an intrinsic and intrabilayer 64Cu chelator, although how radiolabeling impacts drug delivery has not yet been assessed. Here, we show that 64Cu can radiolabel the stable bilayer of preformed Dox-loaded PoP liposomes with inclusion of 1% ethanol without inducing drug leakage. Dox-PoP liposomes labeled with intrabilayer copper behaved nearly identically to unlabeled ones in vitro and in vivo with respect to physical parameters, pharmacokinetics, and CPT efficacy. Positron emission tomography and near infrared fluorescence imaging visualized orthotopic mammary tumors in mice with passive liposome accumulation following administration. A single CPT treatment with 665 nm light (200 J/cm2) strongly inhibited primary tumor growth. Liposomes accumulated in lung metastases, based on NIR imaging. These results establish the feasibility of CPT interventions guided by intrinsic multimodal imaging of Dox loaded stealth PoP liposomes. PMID- 29195045 TI - Divergent Spatiotemporal Interaction of Angiotensin Receptor Blocking Drugs with Angiotensin Type 1 Receptor. AB - Crystal structures of the human angiotensin II type 1 receptor (AT1R) complex with the antihypertensive agent ZD7155 (PDB id: 4YAY ) and the blood pressure medication Benicar (PDB id: 4ZUD ) showed that binding poses of both antagonists are similar. This finding implies that clinically used angiotensin receptor blocking (ARB) drugs may interact in a similar fashion. However, clinically observed differences in pharmacological and therapeutic efficacies of ARBs lead to the question of whether the dynamic interactions of AT1R with ARBs vary. To address this, we performed induced-fit docking (IFD) of eight clinically used ARBs to AT1R followed by 200 ns molecular dynamic (MD) simulation. The experimental Ki values for ARBs correlated remarkably well with calculated free energy with R2 = 0.95 and 0.70 for AT1R-ARB models generated respectively by IFD and MD simulation. The eight ARB-AT1R complexes share a common set of binding residues. In addition, MD simulation results validated by mutagenesis data discovered distinctive spatiotemporal interactions that display unique bonding between an individual ARB and AT1R. These findings provide a reasonably broader picture reconciling the structure-based observations with clinical studies reporting efficacy variations for ARBs. The unique differences unraveled for ARBs in this study will be useful for structure-based design of the next generation of more potent and selective ARBs. PMID- 29195046 TI - Rapid Ordering in "Wet Brush" Block Copolymer/Homopolymer Ternary Blends. AB - The ubiquitous presence of thermodynamically unfavored but kinetically trapped topological defects in nanopatterns formed via self-assembly of block copolymer thin films may prevent their use for many envisioned applications. Here, we demonstrate that lamellae patterns formed by symmetric polystyrene-block poly(methyl methacrylate) diblock copolymers self-assemble and order extremely rapidly when the diblock copolymers are blended with low molecular weight homopolymers of the constituent blocks. Being in the "wet brush" regime, the homopolymers uniformly distribute within their respective self-assembled microdomains, preventing increases in domain widths. An order-of-magnitude increase in topological grain size in blends over the neat (unblended) diblock copolymer is achieved within minutes of thermal annealing as a result of the significantly higher power law exponent for ordering kinetics in the blends. Moreover, the blends are demonstrated to be capable of rapid and robust domain alignment within micrometer-scale trenches, in contrast to the corresponding neat diblock copolymer. These results can be attributed to the lowering of energy barriers associated with domain boundaries by bringing the system closer to an order-disorder transition through low molecular weight homopolymer blending. PMID- 29195054 TI - Bacterial Mechanosensors. AB - Bacteria represent one of the most evolutionarily successful groups of organisms to inhabit Earth. Their world is awash with mechanical cues, probably the most ancient form of which are osmotic forces. As a result, they have developed highly robust mechanosensors in the form of bacterial mechanosensitive (MS) channels. These channels are essential in osmoregulation, and in this setting, provide one of the simplest paradigms for the study of mechanosensory transduction. We explore the past, present, and future of bacterial MS channels, including the alternate mechanosensory roles that they may play in complex microbial communities. Central to all of these functions is their ability to change conformation in response to mechanical stimuli. We discuss their gating according to the force-from-lipids principle and its applicability to eukaryotic MS channels. This includes the new paradigms emerging for bilayer-mediated channel mechanosensitivity and how this molecular detail may provide advances in both industry and medicine. PMID- 29195049 TI - A Solid-State Conceptualization of Information Transfer from Gene to Message to Protein. AB - In this review, we describe speculative ideas and early stage research concerning the flow of genetic information from the nuclear residence of genes to the disparate, cytoplasmic sites of protein synthesis. We propose that this process of information transfer is meticulously guided by transient structures formed from protein segments of low sequence complexity/intrinsic disorder. These low complexity domains are ubiquitously associated with regulatory proteins that control gene expression and RNA biogenesis, but they are also found in the central channel of nuclear pores, the nexus points of intermediate filament assembly, and the locations of action of other well-studied cellular proteins and pathways. Upon being organized into localized cellular positions via mechanisms utilizing properly folded protein domains, thereby facilitating elevated local concentration, certain low complexity domains adopt cross-beta interactions that are both structurally specific and labile to disassembly. These weakly tethered assemblies, we propose, are built to relay the passage of genetic information from one site to another within a cell, ensuring that the process is of extreme fidelity. PMID- 29195050 TI - Resilience of the Oral Microbiota in Health: Mechanisms That Prevent Dysbiosis. AB - Dental diseases are now viewed as a consequence of a deleterious shift in the balance of the normally stable resident oral microbiome. It is known that frequent carbohydrate consumption or reduced saliva flow can lead to caries, and excessive plaque accumulation increases the risk of periodontal diseases. However, when these "disease drivers" are present, while some individuals appear to be susceptible, others are more tolerant or resilient to suffering from undesirable changes in their oral microbiome. Health-maintaining mechanisms that limit the effect of disease drivers include the complex set of metabolic and functional interrelationships that develop within dental biofilms and between biofilms and the host. In contrast, "positive feedback loops" can develop within these microbial communities that disrupt resilience and provoke a large and abrupt change in function and structure of the ecosystem (a microbial "regime shift"), which promotes dysbiosis and oral disease. For instance, acidification due to carbohydrate fermentation or inflammation in response to accumulated plaque select for a cariogenic or periopathogenic microbiota, respectively, in a chain of self-reinforcing events. Conversely, in tolerant individuals, health maintaining mechanisms, including negative feedback to the drivers, can maintain resilience and promote resistance to and recovery from disease drivers. Recently studied health-maintaining mechanisms include ammonia production, limiting a drop in pH that can lead to caries, and denitrification, which could inhibit several stages of disease-associated positive feedback loops. Omics studies comparing the microbiome of, and its interaction with, susceptible and tolerant hosts can detect markers of resilience. The neutralization or inhibition of disease drivers, together with the identification and promotion of health-promoting species and functions, for example, by pre- and probiotics, could enhance microbiome resilience and lead to new strategies to prevent disease. PMID- 29195055 TI - Neuromuscular Junction Formation, Aging, and Disorders. AB - Synapses, the fundamental unit in neuronal circuits, are critical for learning and memory, perception, thinking, and reaction. The neuromuscular junction (NMJ) is a synapse formed between motoneurons and skeletal muscle fibers that is covered by Schwann cells (SCs). It is essential for controlling muscle contraction. NMJ formation requires intimate interactions among motoneurons, muscles, and SCs. Deficits in NMJ formation and maintenance cause neuromuscular disorders, including congenital myasthenic syndrome and myasthenia gravis. NMJ decline occurs in aged animals and may appear before clinical presentation of motoneuron disorders such as amyotrophic lateral sclerosis. We review recent findings in NMJ formation, maintenance, neuromuscular disorders, and aging of the NMJ, focusing on communications among motoneurons, muscles and SCs, and underlying mechanisms. PMID- 29195056 TI - RNA Interference-Mediated Gene Silencing by Branched Tripodal RNAs Does Not Require Dicer Processing. AB - Specific gene silencing through RNA interference (RNAi) holds great promise as the next-generation therapeutic development platform. Previously, we have shown that branched, tripodal interfering RNA (tiRNA) structures could simultaneously trigger RNAi-mediated gene silencing of three target genes with 38 nt-long guide strands associated with Argonaute 2. Herein, we show that the branched RNA structure can trigger effective gene silencing in Dicer knockout cell line, demonstrating that the Dicer-mediated processing is not required for tiRNA activity. The finding of this study confirms the flexibility of the structure of RNAi triggers as well as the length of the guide strand in RNAi-mediated gene silencing. PMID- 29195052 TI - Accountability for Community-Based Programs for the Seriously Ill. AB - Innovation is needed to improve care of the seriously ill, and there are important opportunities as we transition from a volume- to value-based payment system. Not all seriously ill are dying; some recover, while others are persistently functionally impaired. While we innovate in service delivery and payment models for the seriously ill, it is important that we concurrently develop accountability that ensures a focus on high-quality care rather than narrowly focusing on cost containment. The Gordon and Betty Moore Foundation convened a meeting of 45 experts to arrive at guiding principles for measurement, create a starter measurement set, specify a proposed definition of the denominator and its refinement, and identify research priorities for future implementation of the accountability system. A series of articles written by experts provided the basis for debate and guidance in formulating a path forward to develop an accountability system for community-based programs for the seriously ill, outlined in this article. As we innovate in existing population based payment programs such as Medicare Advantage and develop new alternative payment models, it is important and urgent that we develop the foundation for accountability along with actionable measures so that the healthcare system ensures high-quality person- and family-centered care for persons who are seriously ill. PMID- 29195057 TI - Novel Radiotherapy Techniques for Breast Cancer. AB - During the early decades of radiation therapy for breast cancer, local control of disease was documented consistently but, enigmatically, an anticipated impact on breast cancer survival was not observed, leading to confusion in our understanding of the natural history of breast cancer and radiation effects. Now, almost 90 years after its first use in breast cancer, technology developments in diagnostic imaging and radiation therapy have elucidated parts of this enigma. The data now available demonstrate a significant impact of radiation therapy on survival as well as disease control and treatment-related mortality, opening a doorway to understanding the powerful impact of radiation therapy on both breast cancer and critical organs. Efforts are focused on leveraging novel techniques to maximize the benefits of radiation for breast cancer patients. PMID- 29195058 TI - Essential Role of IFT140 in Promoting Dentinogenesis. AB - Primary cilia, with highly regulated cellular sensory functions, play key roles in tissue development and function maintenance. Intraflagellar transport 140 (IFT140) is a subunit of IFT complex A, which is specialized for retrograde transportation in cilia. Mutations of Ift140 are usually associated with syndromic ciliopathy and may cause isolated diseases such as retinal dystrophy, short ribs, and polycystic kidney. However, the role of IFT140 in tooth development has not been well investigated. In this study, a close relationship between IFT140 and dentin formation is disclosed. During tooth development, IFT140 was highly expressed in odontoblasts. To further understand the role of IFT140 in dentinogenesis, Ift140flox/flox/Osx-Cre mouse was generated. The dentin thickness of Ift140flox/flox/Osx-Cre mouse is thinner and the dentin formation is slower than that in control. In vitro, deletion of IFT140 in odontoblasts led to poor odontogenic differentiation, abnormal primary cilia, and decreased Sonic hedgehog signaling molecules. More important, due to loss of primary cilia in odontoblasts by IFT140 deletion, reparative dentin formation was impaired in a tooth-drilling model. These results suggest that cilia gene IFT140 is essential in promoting dentin formation and reparation. PMID- 29195053 TI - PBP2a in beta-Lactam-Resistant Laboratory Mutants and Clinical Isolates: Disruption Versus Reduced Penicillin Affinity. AB - Alterations in PBP2a have been recognized in cefotaxime-resistant laboratory mutants and beta-lactam-resistant clinical isolates of Streptococcus pneumoniae. DNA sequencing revealed fundamental differences between these two settings. Internal stop codons in pbp2a occurred in all three laboratory mutants analyzed, caused by a mutation in pbp2a of mutant C604, and tandem duplications within pbp2a resulting in premature stop codons in another two mutants C403 and C406. In contrast, mosaic PBP2a genes were observed in several penicillin-resistant clinical isolates from South Africa, the Czech Republic, Hungary, and in the clone Poland23F-16, with sequence blocks diverging from sensitive strains by over 4%. Most of these pbp2a variants except pbp2a from the South African strain contained sequences related to pbp2a of Streptococcus mitis B6, confirming that this species serves as reservoir for penicillin-resistance determinants. PMID- 29195051 TI - The Glymphatic System in Central Nervous System Health and Disease: Past, Present, and Future. AB - The central nervous system (CNS) is unique in being the only organ system lacking lymphatic vessels to assist in the removal of interstitial metabolic waste products. Recent work has led to the discovery of the glymphatic system, a glial dependent perivascular network that subserves a pseudolymphatic function in the brain. Within the glymphatic pathway, cerebrospinal fluid (CSF) enters the brain via periarterial spaces, passes into the interstitium via perivascular astrocytic aquaporin-4, and then drives the perivenous drainage of interstitial fluid (ISF) and its solute. Here, we review the role of the glymphatic pathway in CNS physiology, the factors known to regulate glymphatic flow, and the pathologic processes in which a breakdown of glymphatic CSF-ISF exchange has been implicated in disease initiation and progression. Important areas of future research, including manipulation of glymphatic activity aiming to improve waste clearance and therapeutic agent delivery, are also discussed.

PMID- 29195060 TI - Structural Studies and Gene Silencing Activity of siRNAs Containing Cationic Phosphoramidate Linkages. AB - A series of siRNA duplexes containing cationic non-bridging 3',5'-linked phosphoramidate (PN) linkages was designed and synthesized using a combination of phosphoramidite and H-phosphonate chemistries. Modified oligonucleotides were assayed for their thermal stability, helical structure, and ability to modulate the expression of firefly luciferase. We demonstrate that PN modifications of siRNAs are, in general, minimally destabilizing with respect to duplex thermal stability; destabilization can be mitigated through the incorporation of 2' modified RNA-like residues or PN conjugates containing ionizable pendant moieties. We also demonstrate that single cationic dimethylethylenediamine PN linkages have little effect on siRNA potency, whether located in the passenger or guide strand of the duplex. Highly modified siRNA passenger strands were further modified with up to four cationic PN linkages, with little effect on duplex potency or helical structure. We envision that PN modifications could be useful in the production of therapeutic siRNAs with optimal biological properties. PMID- 29195048 TI - Bendamustine-PAMAM Conjugates for Improved Apoptosis, Efficacy, and in Vivo Pharmacokinetics: A Sustainable Delivery Tactic. AB - Successful delivery of a chemotherapeutic agent like bendamustine still remains a challenge in clinical conditions like chronic lymphatic leukemia (CLL), non Hodgkin lymphoma (NHL), and multiple myeloma. We have conjugated bendamustine to polyamidoamine (PAMAM) dendrimers after conjugating with N (hydroxyethyl)maleimide (spacer) via an ester bond. The particle size of PAMAM bendamustine conjugate was 49.8 +/- 2.5 nm. In vitro drug release resulted in sustained release with improved solution stability of drug up to 72 h. In a 24 h cytotoxicity study by MTT assay against human monoblastic leukemia cells (THP-1), the IC50 value for PAMAM-bendamustine was 32.1 +/- 4.8 MUM compared to 50.42 +/- 3.4 MUM and 2303 +/- 106.5 MUM for bendamustine and PAMAM dendrimer, respectively. Significantly higher cell uptake and apoptosis were observed in THP 1 cells by PAMAM-bendamustine conjugate which was confirmed by flow cytometry and confocal laser scanning microscopy. Preliminary in vivo studies undertaken included pharmacokinetics studies, organ distribution studies, and tumor inhibition studies. In healthy Wistar rat model (1CBM IV push model), the pharmacokinetic studies revealed that bioavailability and t1/2 increased significantly, i.e., almost 8.5-fold (193.8 +/- 1.116 vs 22.8 +/- 0.158 MUg mL 1/h) and 5.1-fold (0.75 +/- 0.005 vs 3.85 +/- 0.015 h), respectively, for PAMAM bendamustine conjugate compared to pure bendamustine ( p < 0.05), however, clearance and volume of distribution were found to be decreased compared to those of free drug. The study suggests that PAMAM-bendamustine conjugate was not only stable for the longer period but also least toxic and highly taken up by THP-1 cells to exert an anticancer effect at the reduced dose. Tumor inhibition and biodistribution studies in tumor-bearing BALB/c mice revealed that PAMAM bendamustine conjugate was more effective than the pure drug and showed higher accumulation in the tumor. PMID- 29195063 TI - Metabolic and Endocrine Role of Adipose Tissue During Lactation. AB - The adipose tissue serves an essential role for survival and reproduction in mammals, especially females. It serves primarily as an energy storage organ and is directly linked to the reproductive success of mammals. In wild animals, adipose tissue function is linked to seasonality of the food supply to support fetal growth and milk production. Adipose tissue depots in ruminants and non ruminants can secrete many signal molecules (adipokines) that act as hormones and as pro- and anti-inflammatory cytokines. The visceral adipose tissue especially appears to be more endocrinologically active than other adipose depots. The endocrine function is important for the overall long-term regulation of energy metabolism and plays an important role in the adaptation to lactation in many mammalian species, including humans. Furthermore, endocrine signals from adipose tissue depots contribute to fertility modulation, immune function, and inflammatory response. Energy homeostasis is modulated by changes in feed intake, insulin sensitivity, and energy expenditure, processes that can be influenced by adipokines in the brain and in peripheral tissues.

PMID- 29195062 TI - Compressive Stockings After Hindfoot and Ankle Surgery. AB - BACKGROUND: Swelling and pain are common after foot and ankle procedures. We hypothesized that compressive stockings (CS) treatment after hindfoot surgery would positively influence patient outcomes. METHODS: We undertook this randomized controlled trial in 87 consecutive patients to analyze the clinical effect of CS after hindfoot and ankle surgery and evaluate CS-wearing compliance using sensors that were implanted into CS. Ankle swelling, pain status, quality of life (SF-36 score), and the American Orthopaedic Foot & Ankle Score (AOFAS) were set as the primary end points. The CS wearing time in hours and percentage were investigated as the secondary end points. All participants with CS (group I) were informed about the implanted sensor after the CS were taken off. A subgroup analysis of group I was performed to detect differences between patients with high vs low compliance. RESULTS: At 12 weeks, the results of ankle swelling (mean 234 mm in group I and 232 mm in group II), pain in the visual analog scale (1.7 group I vs 1.9 in group II), the SF-36 score (38 points in group I vs 30 points in group II), and the AOFAS score (a mean of 76 points in both groups) showed no statistical differences between the 2 groups. The mean wearing time was 136 (range, 0-470) hours, which corresponds to a compliance rate of 65%. Sixteen participants had high compliance (>80%, >170 hours), and 21 patients had low or noncompliance. The clinical results of patients with high wearing compliance were not significantly better compared to the results of patients with low compliance. CONCLUSION: CS therapy after ankle and hindfoot surgery was associated with a low wearing compliance and did not influence ankle swelling, function, pain, and the quality of life compared to the control group. Furthermore, the clinical results of patients with high compliance were not better compared to the results of patients with low or noncompliance wearing behavior.

PMID- 29195073 TI - Epigenetic Therapy Ties MYC Depletion to Reversing Immune Evasion and Treating Lung Cancer. AB - Combining DNA-demethylating agents (DNA methyltransferase inhibitors [DNMTis]) with histone deacetylase inhibitors (HDACis) holds promise for enhancing cancer immune therapy. Herein, pharmacologic and isoform specificity of HDACis are investigated to guide their addition to a DNMTi, thus devising a new, low-dose, sequential regimen that imparts a robust anti-tumor effect for non-small-cell lung cancer (NSCLC). Using in-vitro-treated NSCLC cell lines, we elucidate an interferon alpha/beta-based transcriptional program with accompanying upregulation of antigen presentation machinery, mediated in part through double stranded RNA (dsRNA) induction. This is accompanied by suppression of MYC signaling and an increase in the T cell chemoattractant CCL5. Use of this combination treatment schema in mouse models of NSCLC reverses tumor immune evasion and modulates T cell exhaustion state towards memory and effector T cell phenotypes. Key correlative science metrics emerge for an upcoming clinical trial, testing enhancement of immune checkpoint therapy for NSCLC. PMID- 29195074 TI - Myc Cooperates with Ras by Programming Inflammation and Immune Suppression. AB - The two oncogenes KRas and Myc cooperate to drive tumorigenesis, but the mechanism underlying this remains unclear. In a mouse lung model of KRasG12D driven adenomas, we find that co-activation of Myc drives the immediate transition to highly proliferative and invasive adenocarcinomas marked by highly inflammatory, angiogenic, and immune-suppressed stroma. We identify epithelial derived signaling molecules CCL9 and IL-23 as the principal instructing signals for stromal reprogramming. CCL9 mediates recruitment of macrophages, angiogenesis, and PD-L1-dependent expulsion of T and B cells. IL-23 orchestrates exclusion of adaptive T and B cells and innate immune NK cells. Co-blockade of both CCL9 and IL-23 abrogates Myc-induced tumor progression. Subsequent deactivation of Myc in established adenocarcinomas triggers immediate reversal of all stromal changes and tumor regression, which are independent of CD4+CD8+ T cells but substantially dependent on returning NK cells. We show that Myc extensively programs an immune suppressive stroma that is obligatory for tumor progression. PMID- 29195075 TI - An Unexpectedly Complex Architecture for Skin Pigmentation in Africans. AB - Approximately 15 genes have been directly associated with skin pigmentation variation in humans, leading to its characterization as a relatively simple trait. However, by assembling a global survey of quantitative skin pigmentation phenotypes, we demonstrate that pigmentation is more complex than previously assumed, with genetic architecture varying by latitude. We investigate polygenicity in the KhoeSan populations indigenous to southern Africa who have considerably lighter skin than equatorial Africans. We demonstrate that skin pigmentation is highly heritable, but known pigmentation loci explain only a small fraction of the variance. Rather, baseline skin pigmentation is a complex, polygenic trait in the KhoeSan. Despite this, we identify canonical and non canonical skin pigmentation loci, including near SLC24A5, TYRP1, SMARCA2/VLDLR, and SNX13, using a genome-wide association approach complemented by targeted resequencing. By considering diverse, under-studied African populations, we show how the architecture of skin pigmentation can vary across humans subject to different local evolutionary pressures. PMID- 29195076 TI - Migrating Platelets Are Mechano-scavengers that Collect and Bundle Bacteria. AB - Blood platelets are critical for hemostasis and thrombosis and play diverse roles during immune responses. Despite these versatile tasks in mammalian biology, their skills on a cellular level are deemed limited, mainly consisting in rolling, adhesion, and aggregate formation. Here, we identify an unappreciated asset of platelets and show that adherent platelets use adhesion receptors to mechanically probe the adhesive substrate in their local microenvironment. When actomyosin-dependent traction forces overcome substrate resistance, platelets migrate and pile up the adhesive substrate together with any bound particulate material. They use this ability to act as cellular scavengers, scanning the vascular surface for potential invaders and collecting deposited bacteria. Microbe collection by migrating platelets boosts the activity of professional phagocytes, exacerbating inflammatory tissue injury in sepsis. This assigns platelets a central role in innate immune responses and identifies them as potential targets to dampen inflammatory tissue damage in clinical scenarios of severe systemic infection. PMID- 29195077 TI - Epsin-Dependent Ligand Endocytosis Activates Notch by Force. AB - DSL ligands activate Notch by inducing proteolytic cleavage of the receptor ectodomain, an event that requires ligand to be endocytosed in signal-sending cells by the adaptor protein Epsin. Two classes of explanation for this unusual requirement are (1) recycling models, in which the ligand must be endocytosed to be modified or repositioned before it binds Notch and (2) pulling models, in which the ligand must be endocytosed after it binds Notch to exert force that exposes an otherwise buried site for cleavage. We demonstrate in vivo that ligands that cannot enter the Epsin pathway nevertheless bind Notch but fail to activate the receptor because they cannot exert sufficient force. This argues against recycling models and in favor of pulling models. Our results also suggest that once ligand binds receptor, activation depends on a competition between Epsin-mediated ligand endocytosis, which induces cleavage, and transendocytosis of the ligand by the receptor, which aborts the incipient signal. PMID- 29195079 TI - SnapShot: Circadian Clock. AB - Most creatures on this planet possess an ability to anticipate upcoming events in the environment, courtesy of their circadian clocks.

AB - PURPOSE: To introduce in-continuity neck dissection (ND) in squamous cell carcinoma of the buccal mucosa (BMSCC) and to determine its impact on the oncologic outcomes of these patients. MATERIALS AND METHODS: A retrospective review of patients treated for BMSCC from 2006 through 2016 was performed. Kaplan Meier analysis and log-rank test were used to evaluate local control, regional control (RC), distant metastasis (DM), and disease-specific survival (DSS) of in continuity ND versus discontinuous ND in 220 previously untreated patients with BMSCC, followed by a multivariate Cox regression that included all relevant variables. RESULTS: Fifty-three patients received discontinuous ND and 167 patients received in-continuity ND. The 2 groups were comparable. Univariate Kaplan-Meier analysis showed that 5-year DSS rates for the discontinuous ND and in-continuity ND groups were 38 and 62% (P = .023), respectively. The 5-year RC rate for the in-continuity ND group (81%) was significantly better (P = .004) than for the discontinuous ND group (54%). At Cox regression analysis, in continuity ND meaningfully contributed to a higher RC rate and subsequently better DSS. CONCLUSION: Compared with discontinuous ND, in-continuity ND predicted favorable oncologic outcomes in patients with BMSCC. In-continuity ND could be a practical approach in the surgical management of BMSCC. PMID- 29195078 TI - A Next Generation Connectivity Map: L1000 Platform and the First 1,000,000 Profiles. AB - We previously piloted the concept of a Connectivity Map (CMap), whereby genes, drugs, and disease states are connected by virtue of common gene-expression signatures. Here, we report more than a 1,000-fold scale-up of the CMap as part of the NIH LINCS Consortium, made possible by a new, low-cost, high-throughput reduced representation expression profiling method that we term L1000. We show that L1000 is highly reproducible, comparable to RNA sequencing, and suitable for computational inference of the expression levels of 81% of non-measured transcripts. We further show that the expanded CMap can be used to discover mechanism of action of small molecules, functionally annotate genetic variants of disease genes, and inform clinical trials. The 1.3 million L1000 profiles described here, as well as tools for their analysis, are available at https://clue.io.

Thus, the objective of this study was to evaluate the respiratory dynamics of healthy control subjects and those with cystic fibrosis in a submaximal exercise protocol for six minutes on the treadmill, using volumetric capnography parameters (slope 3 [Slp3], Slp3/tidal volume [Slp3/TV], and slope 2 [Slp2]). METHODS: This was a cross-sectional study with 128 subjects (cystic fibrosis, 64 subjects; controls, 64 subjects]. Participants underwent volumetric capnography before, during, and after six minutes on the treadmill. Statistical analysis was performed using the Friedman, Mann-Whitney, and Kruskal-Wallis tests, considering age and sex. An alpha=0.05 was considered. RESULTS: Six minutes on the treadmill evaluation: in cystic fibrosis, volumetric capnography parameters were different before, during, and after six minutes on the treadmill; the same was observed for the controls, except for Slp2. Regarding age, an Slp3 difference was observed in cystic fibrosis patients regardless of age, at all moments, and in controls for age>=12 years; a difference in Slp3/TV was observed in cystic fibrosis and controls, regardless of age; and an Slp2 difference in the cystic fibrosis, regardless of age. Regarding sex, Slp3 and Slp3/TV differences were observed in cystic fibrosis regardless of sex, and in controls in male participants; an Slp2 difference was observed in the cystic fibrosis and female participants. The analysis between groups (cystic fibrosis and controls) indicated that Slp3 and Slp3/TV has identified the CF, regardless of age and sex, while the Slp2 showed the CF considering age. CONCLUSIONS: Cystic fibrosis showed greater values of the parameters before, during, and after exercise, even when stratified by age and sex, which may indicate ventilation inhomogeneity in the peripheral pathways in the cystic fibrosis.

PMID- 29195082 TI - A cell culture platform for Cryptosporidium that enables long-term cultivation and new tools for the systematic investigation of its biology. AB - Cryptosporidium parasites are a major cause of diarrhoea that pose a particular threat to children in developing areas and immunocompromised individuals. Curative therapies and vaccines are lacking, mainly due to lack of a long-term culturing system of this parasite. Here, we show that COLO-680N cells infected with two different Cryptosporidium parvum strains produce sufficient infectious oocysts to infect subsequent cultures, showing a substantial fold increase in production, depending on the experiment, over the most optimistic HCT-8 models. Oocyst identity was confirmed using a variety of microscopic- and molecular-based methods. This culturing system will accelerate research on Cryptosporidium and the development of anti-Cryptosporidium drugs. PMID- 29195085 TI - Clinical and hematological profile in a newborn cohort with hemoglobin SC. AB - OBJECTIVES: Hemoglobin SC is the second most common variant of sickle-cell disease worldwide, after hemoglobin SS. The objectives of the study were to describe the clinical and laboratory characteristics of hemoglobin SC disease in children from a newborn screening program and treated at a blood center. METHODOLOGY: This study assessed a cohort of 461 infants born between 01/01/1999 and 12/31/2012 and followed-up until 12/31/2014. Clinical events were expressed as rates for 100 patient-years, with 95% confidence intervals. Kaplan-Meier survival curves were created. RESULTS: The median age of patients was 9.2 years; 47.5% were female. Mean values of blood tests were: hemoglobin, 10.5g/dL; reticulocytes, 3.4%; white blood cells, 11.24*109/L; platelets, 337.1*109/L; and fetal hemoglobin, 6.3%. Clinical events: acute splenic sequestration in 14.8%, blood transfusion 23.4%, overt stroke in 0.2%. The incidence of painful vaso occlusive episodes was 51 (48.9-53.4) per 100 patient-years and that of infections, 62.2 episodes (59.8-64.8) per 100 patient-years. Transcranial Doppler ultrasonography (n=71) was normal given the current reference values for SS patients. Hydroxyurea was given to ten children, all of whom improvement of painful crises. Retinopathy was observed in 20.3% of 59 children who underwent ophthalmoscopy. Avascular necrosis was detected in seven of 12 patients evaluated, predominantly in the left femur. Echocardiogram compatible with pulmonary hypertension was recorded in 4.6% of 130 children, with an estimated average systolic pulmonary artery pressure of 33.5mmHg. The mortality rate from all causes was 4.3%. CONCLUSIONS: Clinical severity is variable in SC hemoglobinopathy. Several children have severe manifestations similar to those with SS disease. PMID- 29195087 TI - From ancestral peptides to designed proteins. AB - The diversity of modern proteins arose through the combinatorial shuffling and differentiation of a limited number of autonomously folding domain prototypes, but the origin of these prototypes themselves has long remained poorly understood. In recent years, the proposal that they originated by repetition, accretion, and recombination from an ancestral set of peptides, which evolved as cofactors of RNA-based replication and catalysis, has gained wide acceptance, supported by the systematic identification of such ancestral peptides and the experimental recapitulation of the mechanisms by which they could have yielded the first folded proteins. Inspired by this evolutionary process, protein engineers have seized on design from pre-optimized peptide components as a powerful approach to generating proteins with novel topology and functionality. PMID- 29195086 TI - Postmortem MRI and histology demonstrate differential iron accumulation and cortical myelin organization in early- and late-onset Alzheimer's disease. AB - Previous MRI studies reported cortical iron accumulation in early-onset (EOAD) compared to late-onset (LOAD) Alzheimer disease patients. However, the pattern and origin of iron accumulation is poorly understood. This study investigated the histopathological correlates of MRI contrast in both EOAD and LOAD. T2*-weighted MRI was performed on postmortem frontal cortex of controls, EOAD, and LOAD. Images were ordinally scored using predefined criteria followed by histology. Nonlinear histology-MRI registration was used to calculate pixel-wise spatial correlations based on the signal intensity. EOAD and LOAD were distinguishable based on 7T MRI from controls and from each other. Histology-MRI correlation analysis of the pixel intensities showed that the MRI contrast is best explained by increased iron accumulation and changes in cortical myelin, whereas amyloid and tau showed less spatial correspondence with T2*-weighted MRI. Neuropathologically, subtypes of Alzheimer's disease showed different patterns of iron accumulation and cortical myelin changes independent of amyloid and tau that may be detected by high-field susceptibility-based MRI. PMID- 29195088 TI - Early inhibitory control and working memory abilities of children prenatally exposed to methadone. AB - BACKGROUND: Methadone maintenance is the most common method of treating opioid dependent pregnant women. However, little is known about the impact of prenatal methadone exposure on child neurocognitive development. AIMS: To examine the early executive functioning of children born to methadone-maintained mothers, and to assess relations between executive functioning and later emotional and behavioral adjustment. STUDY DESIGN: Prospective longitudinal study. PARTICIPANTS: The sample consisted of 68 methadone-exposed children and 88 non methadone-exposed children. OUTCOME MEASURES: At age 2years, children's inhibitory control and working memory were assessed using the Snack Delay and Three Boxes tasks. At 2 and 4.5years, their emotional and behavioral adjustment was assessed using the caregiver-completed Strengths and Difficulties Questionnaire. RESULTS: Methadone-exposed children had poorer inhibitory control than non-exposed children (p<0.0001). These differences were explained by maternal education and prenatal benzodiazepine use. With respect to working memory, although both groups performed similarly on the first trial set, non exposed children significantly improved their performance on the second trial set (p=0.002), while methadone-exposed children did not (p=0.92). Inhibitory control at age 2years was predictive of higher conduct (p=0.001), hyperactivity (p=0.0001), peer relationship (p=0.02), and total (p<0.0001) problems at 4.5years even after adjustment for behavioral problems at 2years. CONCLUSIONS: Methadone exposed children demonstrate difficulties with inhibitory control and possibly sustained attention/learning. These difficulties were explained by factors correlated with maternal prenatal methadone use. Longer-term follow-up of these children is needed to understand the effects of prenatal methadone exposure and related maternal factors on executive functioning and behavioral adjustment. PMID- 29195089 TI - Immunotoxicity of bisphenol S and F are similar to that of bisphenol A during zebrafish early development. AB - Bisphenol S (BPS) and bisphenol F (BPF) have been increasingly used as alternatives to bisphenol A (BPA) owing to health concerns. The present study aims to evaluate the impact of these two BPA analogs on oxidative stress and the immune system during zebrafish embryonic and larval development. Environmentally relevant levels of BPS and BPF exposure could increase reactive oxygen species (ROS) content, nitric oxide (NO) content, nitric oxide synthase (NOS) activity, and the expression of immunity-related genes in concentration dependent manners during the early developmental stages in zebrafish. At a concentration of 100 MUg/L, BPS and BPF showed similar effects on the immune toxicity of zebrafish as that of BPA. Moreover, BPS and BPF induced both eralpha and nf-kappab expression, and antagonists of estrogen receptor and NF-kappaB blocked the effects on immunity-related gene expression, providing evidence that the two pathways mediate the actions of BPS and BPF on fish immune response and functions. Thus we conclude that the presence of BPS and BPF in the environment, similar to BPA, may also pose risks to ecosystem and human health and cannot be widely used without limitations and precautions.

AB - The effects of five imidazolium ionic liquids with different anions were studied in hydroponically grown wheat seedlings at concentrations of 50, 100, 150, 200, 250, and 300 mg L-1. The results showed that shoots and roots grew shorter and dry weight decreased with increasing concentrations of ionic liquids. Moreover, the antioxidant enzyme activities decreased and malondialdehyde (MDA) content was greater in the leaves of wheat seedlings subjected to ionic liquid (IL) treatments. The order of influence of ionic liquids on these indexes was [C4mim][TfO]> [C4mim][Cl]> [C4mim][BF4]> [C4mim][Lact]> [C4mim][Ala]. A transmission electron microscope (TEM) was used to observe leaf and root cellular structures, such as chloroplast, nucleus, mitochondria, and rough endoplasmic reticulum, in wheat exposed to ionic liquids at a concentration of 150 mg L-1. The results showed that the cellular structures of wheat were affected, and the degree of the effect of five ILs was consistent with the general trend of the measured indexes in this study. Ionic liquids influence the growth of plants by impeding growth, disrupting metabolic physiology and changing cellular structures. The degree of toxicity of imidazolium-based ionic liquids with different anions varies. PMID- 29195092 TI - Dechlorinating performance of Dehalococcoides spp. mixed culture enhanced by tourmaline. AB - Dehalococcoides spp. were extensively studied and applied to in-situ trichloroethylene (TCE) remediation since it is the only genus that can reduce TCE to harmless ethene completely. However, this technology was hindered because of the requirement of electron donor (i.e. hydrogen or fermentable organic substrate). Considering the spontaneous electric field and in-situ hydrogen production capacity of tourmaline, this mineral was used as an environmental friendly bio-promoter for dechlorinating mixed culture containing Dehalococcoides spp. in this work. Research results showed that biodegradation of TCE and the intermediates were both significantly improved by tourmaline. The first-order TCE degradation rate coefficient increased from 0.0125 h-1 for the tourmaline-free system to 0.0306 h-1 for the system combined with 5 g L-1 tourmaline, and ethene production increased by 36%. The outstanding TCE-degrading ability in the tourmaline-bacteria system without the addition of fermentative electron donor (i.e. methanol) indicated that tourmaline could also produce electron donor to support dechlorinating bacteria. Tourmaline could have direct electric biostimulatory effect and indirect enhanced effect associated with water-derived H2 production in the electric field of tourmaline. Meanwhile, PCR-DGGE analysis exhibited that tourmaline could accelerate the succession of a bacterial, dechlorinating community. The distinctive effects of tourmaline on bacteria were related to its stable electric properties. Therefore, tourmaline could be continuously used in the bioremediation. The present study provided a safe, convenient and persistent alternative to the commonly used enhancement approaches for anaerobic reductive dechlorination process. PMID- 29195093 TI - Synthesis of derivatives of cleistopholine and their anti-acetylcholinesterase and anti-beta-amyloid aggregation activity. AB - A series of 6- and 9-substituted cleistopholine derivatives has been designed, synthesized and investigated to inhibit the aggregation of acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and beta-myloid (A beta). Results showed that these synthetic compounds had excellent AChE inhibitory activity and a significant in vitro inhibitory potency toward the self-induced A beta aggregation. When SH-SY5Y cells were treated with these substituted cleistopholine derivatives during they overexpressed the Swedish mutant form of human beta -amyloid precursor protein (APPsw), A beta 42 secretion levels were significantly reduced. According to a parallel artificial membrane permeation assay for BBB, seven out of these sixteen synthetic compounds probably could cross the blood-brain barrier (BBB) to reach their targets in the central nervous system (CNS).

AB - Despite the environmental concerns regarding nickel (Ni) especially in China, it has received little attention in aquatic animals due to its comparatively weak toxicity. In the present study, we explored the bioaccumulation, biokinetics, and subcellular distribution of Ni in an estuarine oyster Crassostrea hongkongensis. We demonstrated that Ni represented a new pattern of bioaccumulation in oysters characterized by rapid elimination and low dissolved uptake. The waterborne uptake rate constant and dietary assimilation efficiency were 0.036L/g/h and 28%, respectively, and dissolved uptake was the predominant exposure route. The efflux rate constant was positively related to tissue Ni concentration, with the highest efflux of 0.155d-1. Such high elimination resulted in a high Ni turnover and steady-state condition reached rapidly, as shown with a 4-week waterborne exposure experiment at different Ni concentrations. Ni in oysters was mainly sequestered in metallothionein-like protein (MTLP), metal-rich granule, and cellular debris. MTLP was the most important binding fraction during accumulation and depuration, and played a dynamic role leading to rapid Ni elimination. Pre exposure to Ni significantly reduced the dissolved uptake, probably accompanied by depressed filtration activity. Overall, the high turnover and regulation of Ni in oysters were achieved by enhanced efflux, suppressed uptake, and sequestration of most Ni into the detoxified pool. PMID- 29195094 TI - Increases in the competitive fitness of West Nile virus isolates after introduction into California. AB - To investigate the phenotypic evolution of West Nile virus (WNV) in California, we competed sixteen isolates made during 2007-08 against COAV997-5nt, a genetically marked clone from the founding 2003 California isolate COAV997-2003. Using in vivo fitness competitions in House Finches (HOFI) and Culex tarsalis mosquitoes, we found that the majority of WNV WN02 and SW03 genotype isolates exhibited elevated replicative fitness in both hosts compared to COAV997-5nt. Increased replicative capacity in HOFIs was not associated with increased mortality, indicating that these isolates had not gained avian virulence. One WN02 isolate from Coachella Valley, a region geographically close to the isolation of COAV997, showed neutral fitness in HOFIs and reduced fitness in Cx. tarsalis. Two isolates from Kern County and Sacramento/Yolo County out-competed COAV997-nt in HOFIs, but were transmitted less efficiently by Cx. tarsalis. Competition demonstrated neutral or increased fitness that appeared independent of both WN02 and SW03 genotypes. PMID- 29195096 TI - Role of neurexin2a in lead-induced locomotor defect in developing zebrafish. AB - Low-dose chronic lead (Pb) exposure interferes with the development of the nervous system, which may lead to learning disabilities, behavioral abnormalities, and mental retardation. Neurexins (Nrxns) are synaptic cell adhesion molecules associated with neurological disorders. We hypothesized that Pb can affect the expression of nrxns during synapse formation and alter the phenotype behavior. Here, apoptosis, nrxns mRNA expression, and alterations of locomotion were examined after exposure to Pb in zebrafish embryos/larvae. To confirm the function of nrxn2a, rescue experiments were performed using beta nrxn2a mRNA microinjection. Pb exposure increased apoptosis and altered locomotor behavior in zebrafish larvae. Quantitative PCR showed that among several synaptic adhesion molecules, only nrxn2a were affected by Pb exposure. Moreover, exposure to Pb at 10MUmol/L upregulated mRNA expression of nrxn1a and nrxn3a at 24h post fertilization (hpf) and downregulated expression at 48 hpf, whereas the expression remained unchanged at 72 hpf. Only the two isoforms of nrxn2a were downregulated by Pb at 10MUmol/L at all three time points. Rescue experiments showed that beta-nrxn2a mRNA injection recovered the decreased locomotor activity and the increased apoptosis induced by Pb. In addition, overexpression of beta nrxn2a mRNA upregulated alpha-nrxn2a. These data indicated that Pb inhibited the expression of nrxn2a genes, which play a critical role in neural development, and further altered the behavior of zebrafish embryos/larvae.

AB - NaHCO3 with three particle size distributions was employed to determine the minimum inerting concentration (MIC, g/m3) for the explosion of 5MUm and 30MUm aluminum dust in a standard 20L spherical chamber and thus examine the effect of particle size on the inhibition efficiency. Results showed that the MIC significantly increases as the aluminum particle size decreases from 30MUm to 5MUm. For 30MUm aluminum, the MIC dramatically decreased with the reduction in the NaHCO3 particle size. By contrast, for 5MUm aluminum, the MIC was nearly independent of the particle size of NaHCO3 in the range studied. Time-scale analysis indicated that the decomposition of NaHCO3 must be faster than the aluminum combustion reaction for effective chemical inhibition. Scanning electron microscopy showed that the particles of the explosion residues of a NaHCO3/Al mixture were considerably larger than those of pure aluminum explosion residues. A diameter ratio betamix was defined to evaluate the degree of incomplete reaction promoted by NaHCO3. The composition of the explosion products was analyzed by X-ray photoelectron spectroscopy, and the data revealed that Na2CO3 and Al2O3 are the major species of the products. An inhibition mechanism was proposed based on these results. PMID- 29195102 TI - Impact of alkali cations on properties of metakaolin and metakaolin/slag geopolymers: Microstructures in relation to sorption of 134Cs radionuclide. AB - Radio-cesium constitutes major environmental threats. Sorption of hazardous species onto geopolymeric sorbents is relatively recent and may give information about the retention mechanisms when geopolymers are applied to immobilize radwastes. Here, Na-MK, K-MK, Na-MKBFS, and K-MKBFS geopolymeric sorbents were synthesized from metakaolin (MK) and blast furnace slag (BFS) and were characterized using XRD, XRF, FT-IR, DTA/TGA and SEM. FT-IR/XRF results clarified the impact of mono-valent alkali cation (M+) in dividing the sorbents into Al rich (sodium-based) and Si-rich (potassium-based). All sorbents were amorphous to semi-crystalline containing mica-phyllosilicates (greater in Si-rich), tobermorites (greater in MKBFS-based), gehlenite, calcite, quartz, hematite and hydrotalcite. Isotherms of 134Cs radionuclide sorption were constructed, being regular with a positive temperature effect. Al-rich sorbents gave higher sorption capacities than Si-rich ones. Na-MK sorbent recorded the more distinctive sorption capacity (74.95mg/g; at 333K). Langmuir, Freundlich and D-R models were used to disclose the capacities and mechanisms governing the sorption processes. Sorption of Cs+ onto the examined sorbents was favorable. All systems were controlled by ion exchange mechanism, except 134Cs/K-MK system which was controlled by physi- sorption mechanism. 134Cs/Na-MK GP system was the only spontaneous among all. The endothermic natures were the common denominator between the tested systems.

AB - Catalytic abatement of 4-chlorophenol, 2,4-dichlorophenol and 2,4-dichlorophenoxy acetic acid in water was investigated by peroxide oxidation over chromium substituted zinc ferrite nanocomposites at ambient conditions. The structural and chemical properties of composites synthesized by sol-gel auto combustion method was studied by X-ray diffraction, Fourier Transform Infra-Red spectroscopy, Transmission Electron Microscopy, surface area, X-ray Fluorescence spectroscopy, Temperature Programmed Reduction and Desorption techniques. Complete removal of 4 CP, DCP and 2,4-D was achieved within 60, 75 and 90min with 96.7/90.5%, 93.88/77.23% and 88.55/62.1% of COD/TOC removal respectively at 298K and 343K. Influence of reaction variables including reaction temperature, oxidant concentration, substrate concentration, catalyst dosage and its composition on the removal efficiency was studied. Kinetic study revealed that wet peroxide oxidation followed a first order kinetic model with rate constant and activation energy of 3.5*10-2min-1/10.7kJ/mole, 9.5*10-3min-1/12.9kJ/mole and 2.29*10-2min 1/17.7kJ/mole respectively for 4-CP, DCP and 2,4-D. The results of five consecutive catalytic runs from X-ray diffraction, Brunauer Emmet Teller surface area and leaching studies from Atomic Absorption Spectrophotometry (AAS) revealed the excellent stability of the catalyst. Scavenging effect of n-butanol on hydroxyl radical indicated a heterogeneous free radical mechanism. PMID- 29195104 TI - Initial psychometrics, outcomes, and correlates of the Repetitive Body Focused Behavior Scale: Examination in a sample of youth with anxiety and/or obsessive compulsive disorder. AB - BACKGROUND: Body-Focused Repetitive Behaviors (BFRBs), including skin-picking, hair-pulling, and nail-biting, commonly occur in youth, even at elevated/problematic levels, and are associated with a number of other psychiatric symptoms. The present study examined the internal consistency of a brief screening tool for BFRBs as well as the prevalence, severity, and correlates of BFRBs in a sample of youth with a primary anxiety or obsessive compulsive disorder (OCD). METHODS: Ninety-three youth-parent dyads presenting for treatment for anxiety or OCD completed study measures including the Repetitive Body Focused Behavior Scale - Parent (RBFBS), which includes subscales for skin-picking, hair-pulling, and nail-biting, as well as a number of additional clinician-, parent-, and child-rated scales. RESULTS: The RBFBS demonstrated good to excellent internal consistency. BFRBs were endorsed in 55% of youths, with elevated levels in 27%. Skin-picking was the most common BFRB (38%), followed by nail-biting (34%) and hair-pulling (4%). Youth with BFRBs, as compared to those without, were rated as more avoidant by their parents. Among those with BFRBs, more avoidant tendencies, anxiety sensitivity, and child-rated panic, separation, and generalized anxiety symptoms were associated with elevated BFRB severity. BFRBs were equally common but more likely to be elevated among youth with a primary anxiety, than OCD, diagnosis. DISCUSSION: Results provide initial support for the RBFBS as a brief screening tool for the three common BFRBs. In addition, the results suggest avoidant tendencies and physical manifestations of distress may be particularly relevant to the escalation of BFRB symptoms in youth. PMID- 29195105 TI - LGI1 antibody encephalitis - Detailed clinical, laboratory and radiological description of 13 cases in China. AB - BACKGROUND AND PURPOSE: LGI1 antibody encephalitis is a synaptic autoimmune disorder that was first reported in 2010. To date, LGI1 antibody encephalitis is a widely-recognized disease in neurology and psychiatry. In order to aid clinical recognition of the condition, we analyze the clinical characteristics of 13 Chinese LGI1 antibody encephalitis patients. METHODS: We analyzed clinical features of patients admitted to the West China Hospital who had been diagnosed with LGI1 antibody encephalitis from 2015 to 2017. RESULTS: The median age of the 13 patients was 40.5years. There were 8 female patients, and 1 patient younger than 20years. The initial symptoms in 6 patients (46%) were psychiatric in nature. After treatment, 10 patients (77%) recovered gradually, and 11 patients (85%) showed improvement of psychiatric symptoms. CONCLUSIONS: LGI1 antibody encephalitis should be suspected in patients who developed a rapid change in behavior or psychosis, seizures, or cognition. Timely diagnosis and treatment may yield favorable prognosis. PMID- 29195106 TI - Mental health of caregivers of individuals with disabilities: Relation to Suicidal Ideation. AB - OBJECTIVE: The mental health of caregivers of individuals with disabilities is frequently neglected. This study investigated mental health status and Suicidal Ideation (SI) among caregivers and examined the predictive factors for SI. METHOD: Caregivers of individuals with physical or mental disabilities in a tertiary hospital in southern Taiwan were recruited through snowball sampling. They were assessed by self-report questionnaires, consisting of the Taiwanese Depression Questionnaire and a subset of the three-item Chinese Health Questionnaire, to assess probable depression and common mental disorders (CMDs), with cutoff points of 19 and 3, respectively. RESULTS: Among 255 caregivers, 32.9% had probable depression, 37.6% had probable CMDs, and 18.8% experienced SI. The level of SI was correlated with primary caregivers (p=0.015), lack of support from co-caregivers (p=0.023), caring for younger patients (p=0.010), caring for patients with mental disability (p=0.019) or catastrophic diseases (p=0.005), and caregivers' probable depression (p<0.001) and CMDs (p<0.001). Regression analysis predicted the greatest SI among caregivers caring for younger patients (odds ratio [OR]=0.98, p=0.048) and for patients with catastrophic diseases (OR=3.15, p=0.008), as well as for caregivers with probable depression (OR=3.90, p=0.010) or CMDs (OR=9.40, p<0.001). CONCLUSIONS: When examining SI, clinicians should be aware of the mental health of caregivers who are responsible for people with disability. In particular, they should be vigilant regarding caregivers of individuals who are of younger age or have catastrophic diseases and regarding caregivers who exhibit probable depression and CMDs. PMID- 29195107 TI - A cross-national study to objectively evaluate the quality of diverse simulation approaches for undergraduate nursing students. AB - The aim of this paper is to report the results of a cross-national study that evaluated a range of simulation sessions using an observation schedule developed from evidence-based quality indicators. Observational data were collected from 17 simulation sessions conducted for undergraduate nursing students at three universities in Australia and the United Kingdom. The observation schedule contained 27 questions that rated simulation quality. Data were collected by direct observation and from video recordings of the simulation sessions. Results indicated that the highest quality scores were for provision of learning objectives prior to the simulation session (90%) and debriefing (72%). Student preparatiosn and orientation (67%) and perceived realism and fidelity (67%) were scored lower than other components of the simulation sessions. This observational study proved to be an effective strategy to identify areas of strength and those needing further development to improve simulation sessions. PMID- 29195108 TI - Novel combined index of cardiometabolic risk related to periarterial fat improves the clinical prediction for coronary artery disease complexity. AB - BACKGROUND AND AIMS: Cardiovascular (CV) risk assessment based on conventional risk factors has a limited performance in the prediction of obstructive coronary artery disease (CAD). Therefore, our aim was to provide a complete assessment on the associations between single or combined cardiovascular ultrasound indexes and the complexity of CAD in high and very-high risk patients. METHODS: Two hundred fifteen patients scheduled for elective coronary angiography were enrolled in the study (F/M: 80/135 pts; age: 61.8 +/- 7.9 years). Detailed clinical characteristics, including several obesity parameters, and the following ultrasound indexes were obtained: carotid intima-media thickness (IMT) and extra media thickness (EMT), epicardial fat thickness (EFT) and intra-abdominal fat thickness (IAT). CAD severity and complexity were assessed based on the well evidenced SYNTAX score (SS) algorithm. RESULTS: The study patients (79% with a very high CV risk) had central obesity (77%), and arterial hypertension (81%), one-third (37%) had diabetes and most of the individuals (74%) were current or previous smokers. In the study group, male sex, higher number of CV risk factors, diabetes and increased carotid vascular indexes (IMT or EMT >= 900 MUm) were associated with significantly higher SS (p < 0.05). Paradoxically, obese patients revealed a significantly lower SS compared to non-obese individuals (3.65 +/- 6.66 vs. 5.93 +/- 8.8; p < 0.01), which was not explained by the number of CV risk factors or age. All the ultrasound indexes (except for visceral fat - IAT) revealed significant associations with the SS and the highest correlation coefficient was found for PATIMA combined index (r = 0.45; p < 0.01). Hence, none of the obesity-related clinical indexes showed any associations with CAD complexity. Multivariate regression analysis showed that male sex, chronic kidney disease and the PATIMA index were independently associated with the Syntax Score. The ROC analysis showed that the highest sensitivity (71% and 82%) and specificity (77% and 72%) in prediction of either SS > 1 or SS > 7 were found for the combined PATIMA index (negative predictive value = 92% for SS > 7). CONCLUSIONS: We present the first study showing that a combination of ultrasound indexes related to periarterial fat and vascular wall (PATIMA index) is associated with more complex CAD in high and very-high risk patients. PATIMA index revealed improved predictive value compared to other single ultrasound indexes and clinical risk assessment. PMID- 29195109 TI - Association of alcohol consumption and aortic calcification in healthy men aged 40-49 years for the ERA JUMP Study. AB - BACKGROUND AND AIMS: Several studies have reported a significant inverse association of light to moderate alcohol consumption with coronary heart disease (CHD). However, studies assessing the relationship between alcohol consumption and atherosclerosis have reported inconsistent results. The current study was conducted to determine the relationship between alcohol consumption and aortic calcification. METHODS: We addressed the research question using data from the population-based ERA-JUMP Study, comprising of 1006 healthy men aged 40-49 years, without clinical cardiovascular diseases, from four race/ethnicities: 301 Whites, 103 African American, 292 Japanese American, and 310 Japanese in Japan. Aortic calcification was assessed by electron-beam computed tomography and quantified using the Agatston method. Alcohol consumption was categorized into four groups: 0 (non-drinkers), <=1 (light drinkers), >1 to <=3 (moderate drinkers) and >3 drinks per day (heavy drinkers) (1 drink = 12.5 g of ethanol). Tobit conditional regression and ordinal logistic regression were used to investigate the association of alcohol consumption with aortic calcification after adjusting for cardiovascular risk factors and potential confounders. RESULTS: The study participants consisted of 25.6% nondrinkers, 35.3% light drinkers, 23.5% moderate drinkers, and 15.6% heavy drinkers. Heavy drinkers [Tobit ratio (95% CI) = 2.34 (1.10, 4.97); odds ratio (95% CI) = 1.67 (1.11, 2.52)] had significantly higher expected aortic calcification score compared to nondrinkers, after adjusting for socio-demographic and confounding variables. There was no significant interaction between alcohol consumption and race/ethnicity on aortic calcification. CONCLUSIONS: Our findings suggest that heavy alcohol consumption may be an independent risk factor for atherosclerosis.

AB - Single-prime negative priming refers to a phenomenon whereby repeating a single prime as a probe target slows responses to that target. This phenomenon is modulated by cognitive control when the contingency between the prime and probe target is higher than chance. The present study investigated the role of prime awareness and awareness of the contingency within the control mechanism during single-prime negative priming. Results showed that while single-prime negative priming occurred regardless of participant awareness, the control mechanism was modulated by prime awareness and perceived contingency. PMID- 29195110 TI - Brachial artery diameter as a marker for cardiovascular risk assessment: FMD-J study. AB - BACKGROUND AND AIMS: Baseline brachial artery (BBA) diameter has been reported to be a potential confounding factor of flow-mediated vasodilation (FMD). The purpose of this study was to evaluate the relationships between BBA diameter and cardiovascular risk factors and compare the diagnostic accuracy of BBA diameter in subjects without cardiovascular risk factors and patients with cardiovascular disease (CVD) with that of FMD. METHODS: We measured BBA diameter and FMD in 5695 male subjects. In addition, we retrospectively investigated the incidence of cardiovascular events using another population sample consisting of 440 male subjects, to compare the accuracy of BBA diameter with that of FMD in predicting cardiovascular events. RESULTS: BBA diameter and FMD significantly correlated with age, body mass index, systolic blood pressure, diastolic blood pressure, triglycerides, high-density lipoprotein cholesterol, and glucose as well as Framingham risk score. The prevalence of cardiovascular risk factors and CVD increased with the increase in BBA diameter and FMD. Area under the curve (AUC) value of the receiver operating characteristic (ROC) curve for BBA diameter to diagnose subjects without cardiovascular risk factors (0.59 vs. 0.62, p = 0.001) or patients with CVD (0.58 vs. 0.64, p < 0.001) was significantly lower than that for FMD. In the retrospective study, the AUC value of the ROC curve for BBA diameter to predict first major cardiovascular events was significantly lower than that of FMD (0.50 vs. 0.62, p = 0.03). CONCLUSIONS: In men, BBA diameter was inferior to FMD for assessment of cardiovascular risk. PMID- 29195112 TI - Promoting honesty in young children through observational learning. AB - The observational learning approach, developed more than a half century ago, suggests that it is possible to promote desirable social behaviors through peer observation. However, this idea has yet to be put to a rigorous empirical test. The current research sought to fill this gap by examining whether honesty can be promoted in children by allowing them to observe a peer's display of honest behavior. The dependent measure was whether 5-year-old children who had cheated by peeking in a guessing game would confess to it. Study 1 showed that simply observing a classmate confess to peeking did not promote honesty. However, children who observed a classmate confess to peeking and receive praise and a small prize from an experimenter did became more honest. Study 2 replicated the effect with a weaker manipulation that involved praise for the confessing peer but no prize, which suggests that verbal feedback alone was a sufficient benefit. These findings point to new strategies for promoting honesty in young children and demonstrate that young children's observations of the social consequences of others' sociomoral behavior can help them to guide their own behavior. PMID- 29195113 TI - A case of multiple sclerosis and necrotizing autoimmune myopathy with anti-SRP antibodies. AB - Only few reports exist regarding the coexistence of multiple sclerosis (MS) and autoimmune myopathies. We describe the case of a man with a long history of undiagnosed left lower limb motor impairment who was hospitalized for subacute onset of a myopathic syndrome. In addition, neurological examination revealed sensory impairment and pyramidal signs in the left limbs. Muscle biopsy revealed a necrotizing myopathy and serum anti-signal recognition particle (SRP) antibodies were found. Brain and spinal cord MRI displayed several non-enhancing demyelinating lesions, and CSF-restricted oligoclonal bands were detected. Multimodal evoked potentials showed increased latency of central conduction. Total body PET-CT did not reveal malignancies. A final diagnosis of anti-SRP necrotizing autoimmune myopathy (NAM) and MS was made, and subsequent therapy with azathioprine resulted in a complete stability for both diseases during the follow up. To the best of our knowledge this is the first reported case of concomitant NAM and MS. PMID- 29195114 TI - Cutaneous anaplastic large cell lymphoma in a multiple sclerosis patient receiving Fingolimod. AB - BACKGROUND: Previous reports of cutaneous neoplastic lesions secondary to Fingolimod treatment among multiple sclerosis patients. OBJECTIVE: Reporting a case of cutaneous large cell lymphoma in a multiple sclerosis patient during Fingolimod treatment. METHOD: Case study. RESULT: Our patient developed CD30+ cutaneous large cell lymphoma two years after initiation of Fingolimod treatment and her symptoms regressed following the cessation of treatment. CONCLUSION: This report indicates that cutaneous lymphoid neoplasms should be considered a possible side effect among patients receiving Fingolimod. PMID- 29195115 TI - Effect of dietary carbohydrates and time of year on ACTH and cortisol concentrations in adult and aged horses. AB - Diagnosis of equine pituitary pars intermedia dysfunction (PPID) remains a challenge as multiple factors (stress, exercise, and time of year) influence ACTH and cortisol concentrations. To assess endocrine status in a study designed to evaluate the effects of age and diet on glucose and insulin dynamics, we performed thyrotropin-releasing hormone (TRH) stimulation tests and overnight dexamethasone suppression tests in March, May, August, and October on 16 healthy Thoroughbred and Standardbred mares and geldings. Horses were grouped by age: adult (mean +/- SD; 8.8 +/- 2.9 yr; n = 8) and aged (20.6 +/- 2.1 yr; n = 8). None of the horses showed clinical signs (hypertrichosis, regional adiposity, skeletal muscle atrophy, lethargy) of pituitary pars intermedia dysfunction. Horses were randomly assigned to groups of 4, blocked for age, and fed grass hay plus 4 isocaloric concentrate diets (control, starch-rich, fiber-rich, and sugar rich) using a balanced Latin square design. Data were analyzed using a multivariable linear mixed regression model. Baseline ACTH was significantly higher in aged horses (mean +/- standard error of the mean; 60.0 +/- 10.7 pg/mL) adapted to the starch-rich diet compared to adult horses (15.7 +/- 12.0 pg/mL) on the same diet (P = 0.017). After controlling for age and diet, baseline ACTH concentrations were significantly increased in October (57.7 +/- 7.1 pg/mL) compared to March (13.2 +/- 7.1 pg/mL; P < 0.001), May (12.4 +/- 7.1 pg/mL; P < 0.001), and August (24.2 +/- 7.1 pg/mL; P < 0.001), whereas post-TRH ACTH was higher in August (376.6 +/- 57.6 pg/mL) and October (370.9 +/- 57.5 pg/mL) compared to March (101.9 +/- 57.3 pg/mL; P < 0.001) and May (74.5 +/- 57.1 pg/mL; P < 0.001). Aged horses had significantly higher post-dexamethasone cortisol on the starch-rich diet (0.6 +/- 0.1 MUg/dL) compared to the sugar-rich diet (0.2 +/ 0.1 MUg/dL; P = 0.021). Post-dexamethasone cortisol was significantly higher in October (0.6 +/- 0.1 MUg/dL) compared to March (0.3 +/- 0.1 MUg/dL; P = 0.005), May (0.2 +/- 0.1 MUg/dL; P < 0.001), and August (0.3 +/- 0.1 MUg/dL; P = 0.004). Breed did not influence ACTH or cortisol measurements. In conclusion, in addition to age and time of year, diet is a potential confounder as animals on a starch rich diet may be incorrectly diagnosed with pituitary pars intermedia dysfunction. PMID- 29195116 TI - PD-L1 status does not predict the outcome of BRAF inhibitor therapy in metastatic melanoma. AB - BACKGROUND: Targeted therapies with BRAF plus MEK inhibitors (BRAFi; MEKi) represent the major treatment strategy for patients with BRAF-mutated metastatic melanoma (MM). Previous analyses suggested a correlation between programmed death ligand 1 (PD-L1) expression in tumour tissues and the outcome of targeted therapies. This study investigated PD-L1 as a potential predictive biomarker of BRAFi-based targeted therapies in MM patients. PATIENTS AND METHODS: We analysed two independent cohorts of BRAF V600-mutated MM patients undergoing BRAFi-based therapies for PD-L1 expression in pre-treatment tumour tissues. The oligocentre cohort 1 included 83 patients whose tumour tissues were analysed retrospectively with the anti-PD-L1 antibody clone E1L3N. The multicentre cohort 2 included 58 patients whose tumour tissues were analysed prospectively within the framework of the "Registry of the Arbeitsgemeinschaft Dermatologische Onkologie" (ADOREG) and "Tissue Registry in Melanoma" (TRIM) project using the anti-PD-L1 antibody clone 28-8. RESULTS: PD-L1 expression in pre-treatment tumour tissue did not correlate with response or survival to BRAFi-based therapies in both MM patient cohorts. This finding was not influenced by retrospective versus prospective immunohistochemistry analyses, oligocentre versus multicentre cohorts or the different anti-PD-L1 antibody clones used. In cohort 1, PD-L1 positivity was detected in tumour tissue of 41.0% and 18.1% of patients (cut-off 1% and 5%, respectively). In cohort 2, 58.6% and 39.7% of patients showed PD-L1 positivity (cut-off 1% and 5%, respectively). CONCLUSION: In two independent cohorts including a total of 141 MM patients, PD-L1 expression in tumour tissue did not correlate with the outcome of BRAFi-based treatment. Therefore, PD-L1 cannot be recommended for the use as a predictive biomarker of BRAFi-based therapy in BRAF V600-mutated MM. PMID- 29195117 TI - Surgical treatment options following chemotherapy plus cetuximab or bevacizumab in metastatic colorectal cancer-central evaluation of FIRE-3. AB - BACKGROUND: The FIRE-3 trial investigated combination chemotherapy plus either cetuximab or bevacizumab in patients with untreated metastatic colorectal cancer (mCRC) not scheduled for upfront surgery. We aimed to determine the number of patients who present with potentially resectable disease during systemic first line therapy and to compare the findings with study reports concerning resections and outcome. PATIENTS AND METHODS: This evaluation of 448 patients was performed as central review blinded for treatment, other reviewers' evaluations and conducted interventions. Resectability was defined if at least 50% of the reviewers recommended surgical-based intervention. Overall survival was assessed by Kaplan-Meier method. RESULTS: Resectability increased from 22% (97/448) at baseline before treatment to 53% (238/448) at best response (P < 0.001), compared with an actual secondary resection rate for metastases of 16% (72/448). At baseline (23% versus 20%) and best response (53% versus 53%), potential resectability of metastases in this molecular unselected population was similar in cetuximab-treated patients versus bevacizumab-treated patients and not limited to patients with one-organ disease. The actual resection rate of metastases was significantly associated with treatment setting (P = 0.02; university hospital versus hospital/practice). Overall survival was 51.3 months (95% confidence interval [CI] 35.9-66.7) in patients with resectable disease who received surgery, 30.8 months (95% CI 26.6-34.9) in patients with resectable disease without surgery and 18.6 months (95% CI 15.8-21.3) in patients with unresectable disease (P < 0.001). CONCLUSIONS: Our findings illustrate the potential for conversion to resectability in mCRC, certain reluctance towards metastatic resections in clinical practice and the need for pre-planned and continuous evaluation for metastatic resection in high-volume centres.

AB - The p53 transcription factor is mutated in over half of human cancers, and p53 null mice are highly predisposed to cancer, highlighting p53s essential role in tumor suppression. Studies in mouse models have revealed that p53 cell cycle arrest and apoptosis responses to acute DNA damage signals are dispensable for tumor suppression, prompting a search for new mechanisms underlying p53-mediated cancer suppression. p53 responds to other types of stress signals and regulates a host other cellular processes, including maintenance of genomic stability, metabolism, stemness, non-apoptotic cell death, migration/invasion, and cell signaling, any or all of which could be fundamental for suppressing carcinogenesis. The ability of p53 to govern numerous transcriptional programs and cellular functions likely explains its potent tumor suppressor activity. PMID- 29195119 TI - Interleukin 11 is upregulated in preeclampsia and leads to inflammation and preeclampsia features in mice. AB - Preeclampsia is a dangerous pregnancy complication, which is often associated with fetal growth restriction and can have serious life-long effects for both mother and baby. While the establishment of the placenta in the first trimester is the sentinel event in the development of preeclampsia little is known of the critical mechanisms of placentation that lead to the syndrome. Locally produced inflammatory cytokines are thought to play a role in the development of preeclampsia. This review summarizes the evidence that interleukin 11 is dysregulated in preeclampsia and contributes to the initiation of preeclampsia via effects on placentation. It discusses the benefits and drawbacks of targeting IL11 as a novel treatment option for preeclampsia. PMID- 29195120 TI - Advances in cellulosic conversion to fuels: engineering yeasts for cellulosic bioethanol and biodiesel production. AB - Cellulosic fuels are expected to have great potential industrial applications in the near future, but they still face technical challenges to become cost competitive fuels, thus presenting many opportunities for improvement. The economical production of viable biofuels requires metabolic engineering of microbial platforms to convert cellulosic biomass into biofuels with high titers and yields. Fortunately, integrating traditional and novel engineering strategies with advanced engineering toolboxes has allowed the development of more robust microbial platforms, thus expanding substrate ranges. This review highlights recent trends in the metabolic engineering of microbial platforms, such as the industrial yeasts Saccharomyces cerevisiae and Yarrowia lipolytica, for the production of renewable fuels. PMID- 29195121 TI - Timing of CRISPR/Cas9-related mRNA microinjection after activation as an important factor affecting genome editing efficiency in porcine oocytes. AB - Recently, successful one-step genome editing by microinjection of CRISPR/Cas9 related mRNA components into the porcine zygote has been described. Given the relatively long gestational period and the high cost of housing swine, the establishment of an effective microinjection-based porcine genome editing method is urgently required. Previously, we have attempted to disrupt a gene encoding alpha-1,3-galactosyltransferase (GGTA1), which synthesizes the alpha-Gal epitope, by microinjecting CRISPR/Cas9-related nucleic acids and enhanced green fluorescent protein (EGFP) mRNA into porcine oocytes immediately after electrical activation. We found that genome editing was indeed induced, although the resulting blastocysts were mosaic and the frequency of modified cells appeared to be low (50%). To improve genome editing efficiency in porcine oocytes, cytoplasmic injection was performed 6 h after electrical activation, a stage wherein the pronucleus is formed. The developing blastocysts exhibited higher levels of EGFP. Furthermore, the T7 endonuclease 1 assay and subsequent sequencing demonstrated that these embryos exhibited increased genome editing efficiencies (69%), although a high degree of mosaicism for the induced mutation was still observed. Single blastocyst-based cytochemical staining with fluorescently labeled isolectin BS-I-B4 also confirmed this mosaicism. Thus, the development of a technique that avoids or reduces such mosaicism would be a key factor for efficient knock out piglet production via microinjection. PMID- 29195122 TI - Norwegian monitoring (1990-2015) of the marine environment around the sunken nuclear submarine Komsomolets. AB - Norway has monitored the marine environment around the sunken Russian nuclear submarine Komsomolets since 1990. This study presents an overview of 25 years of Norwegian monitoring data (1990-2015). Komsomolets sank in 1989 at a depth of 1680 m in the Norwegian Sea while carrying two nuclear torpedoes in its armament. Subsequent Soviet and Russian expeditions to Komsomolets have shown that releases from the reactor have occurred and that the submarine has suffered considerable damage to its hulls. Norwegian monitoring detected 134Cs in surface sediments around Komsomolets in 1993 and 1994 and elevated activity concentrations of 137Cs in bottom seawater between 1991 and 1993. Since then and up to 2015, no increased activity concentrations of radionuclides above values typical for the Norwegian Sea have been observed in any environmental sample collected by Norwegian monitoring. In 2013 and 2015, Norwegian monitoring was carried out using an acoustic transponder on the sampling gear that allowed samples to be collected at precise locations, ~20 m from the hull of Komsomolets. The observed 238Pu/239,240Pu activity ratios and 240Pu/239Pu atom ratios in surface sediments sampled close to Komsomolets in 2013 did not indicate any releases of Pu isotopes from reactor or the torpedo warheads. Rather, these values probably reflect the overprinting of global fallout ratios with fluxes of these Pu isotopes from long range transport of authorised discharges from nuclear reprocessing facilities in Northern Europe. However, due to the depth at which Komsomolets lies, the collection of seawater and sediment samples in the immediate area around the submarine using traditional sampling techniques from surface vessels is not possible, even with the use of acoustic transponders. Further monitoring is required in order to have a clear understanding of the current status of Komsomolets as a potential source of radioactive contamination to the Norwegian marine environment. Such monitoring should involve the use of ROVs or submersibles in order to obtain samples next to and within the different compartments of the submarine. PMID- 29195123 TI - Uranium(VI) sorption complexes on silica in the presence of calcium and carbonate. AB - Uranium sorption on minerals and related solids depends to a large degree on its aqueous speciation. The present work attempts to understand the U(VI) sorption behavior on silica under environmentally relevant conditions, i.e. at neutral to weakly alkaline pH and in the presence of dissolved calcium and carbonate. Under these conditions, Ca(UO2)(CO3)32- and Ca2(UO2)(CO3)3(aq) complexes emerge as the dominant aqueous U(VI) species. The U(VI) sorption affinity was measured as a function of contact time, solution pH, and humic acid. The U(VI) sorption decreased with increase of pH and was not affected by the addition of 50 mg/L humic acid. On the other hand, nitric acid was more effective than EDTA and carbonate at desorbing U(VI). Generally, the U(VI) sorbed on silica at neutral pH was less readily desorbed than that sorbed at higher pH values. Therefore, the U(VI) complex favorably sorbed on silica at the neutral pH is more strongly bound to the silica surface than that sorbed at higher pH values. Time-resolved laser fluorescence spectroscopy confirmed the results of the batch sorption experiments and revealed the presence of two surface U(VI) complexes with fluorescence lifetimes 251 +/- 8 MUs and 807 +/- 24 MUs.

AB - We examined whether electroconvulsive therapy (ECT) plus medications ("STABLE + PHARM" group) had superior HRQOL compared with medications alone ("PHARM" group) as continuation strategy after successful acute right unilateral ECT for major depressive disorder (MDD). We hypothesized that scores from the Medical Outcomes Study Short Form-36 (SF-36) would be higher during continuation treatment in the "STABLE + PHARM" group versus the "PHARM" group. The overall study design was called "Prolonging Remission in Depressed Elderly" (PRIDE). Remitters to the acute course of ECT were re-consented to enter a 6 month RCT of "STABLE + PHARM" versus "PHARM". Measures of depressive symptoms and cognitive function were completed by blind raters; SF-36 measurements were patient self-report every 4 weeks. Participants were 120 patients >60 years old. Patients with dementia, schizophrenia, bipolar disorder, or substance abuse were excluded. The "PHARM" group received venlafaxine and lithium. The "STABLE + PHARM" received the same medications, plus 4 weekly outpatient ECT sessions, with additional ECT session as needed. Participants were mostly female (61.7%) with a mean age of 70.5 +/- 7.2 years. "STABLE + PHARM" patients received 4.5 +/- 2.5 ECT sessions during Phase 2. "STABLE + PHARM" group had 7 point advantage (3.5-10.4, 95% CI) for Physical Component Score of SF-36 (P < 0.0001), and 8.2 point advantage (4.2 12.2, 95% CI) for Mental Component Score (P < 0.0001). Additional ECT resulted in overall net health benefit. Consideration should be given to administration of additional ECT to prevent relapse during the continuation phase of treatment of MDD.

AB - Many cities are making significant financial investments in cycling infrastructure with the aim of making cycling safer for riders of all ages and abilities. Methods for evaluating cycling safety tend to summarize average change for a city or emphasize change on a single road segment. Few spatially explicit approaches are available to evaluate how patterns of safety change throughout a city due to cycling infrastructure investments or other changes. Our goal is to demonstrate a method for monitoring changes in the spatial-temporal distribution of cycling incidents across a city. Using cycling incident data provided by the Insurance Corporation of British Columbia, we first compare planar versus network constrained kernel density estimation for visualizing incident intensity across the street network of Vancouver, Canada. Second, we apply a change detection algorithm explicitly designed for detecting statistically significant change in kernel density estimates. The utility of network kernel density change detection is demonstrated through the comparison of cycling incident densities following the construction of two cycle tracks in the downtown core of Vancouver. The methods developed and demonstrated for this study provide city planners, transportation engineers and researchers a means of monitoring city-wide change in the intensity of cycling incidents following enhancements to cycling infrastructure or other significant changes to the transportation network. PMID- 29195126 TI - Stimulation of Interferon-Stimulated Gene 20 by Thyroid Hormone Enhances Angiogenesis in Liver Cancer. AB - Thyroid hormone, 3,3',5-triiodo-l-thyronine (T3), mediates several physiological processes, including embryonic development, cellular differentiation and cell proliferation, via binding to its nuclear thyroid receptors (TR). Previous microarray and Chromatin immunoprecipitation (ChIP)-on-ChIP analyses have revealed that interferon-stimulated gene 20 kDa (ISG20), an exoribonuclease involved in the antiviral function of interferon, is up-regulated by T3 in HepG2 TR cells. However, the underlying mechanisms of ISG20 action in tumor progression remain unknown to date. Here, we verified induction of ISG20 mRNA and protein expression by T3 in HepG2-TR cells. Based on the ChIP-on-ChIP database, potential thyroid hormone responsive element of the ISG20 promoter region was predicted, and the result confirmed with the ChIP assay. Functional assays showed that forced expression of ISG20 leads to significant promotion of metastasis and angiogenesis, both in vitro and in vivo. Furthermore, the angiogenic-related protein, interleukin-8 (IL-8), was up-regulated through a T3-mediated increase in ISG20, as determined using a human angiogenesis array kit. Induction of IL-8 signaling activated the p-JAK2/p-STAT3 pathway, in turn, leading to promotion of tumor metastasis and angiogenesis. Furthermore, ISG20 overexpression in hepatocellular carcinoma (HCC) specimens was positively correlated with clinical parameters, including vascular invasion, alpha-fetoprotein and tumor size. Higher ISG20 expression was significantly correlated with poorer recurrence-free survival in HCC patients. Our results collectively indicate higher TR-dependent expression of ISG20 in a subset of HCC, supporting an oncogenic role in HCC progression. PMID- 29195127 TI - Rapamycin Synergizes with Cisplatin in Antiendometrial Cancer Activation by Improving IL-27-Stimulated Cytotoxicity of NK Cells. AB - Natural killer (NK) cell function is critical for controlling initial tumor growth and determining chemosensitivity of the tumor. A synergistic relationship between rapamycin and cisplatin in uterine endometrial cancer (UEC) in vitro has been reported, but the mechanism and the combined therapeutic strategy for endometrial cancer (EC) are still unknown. We found a positive correlation between the level of IL-27 and the differentiated stage of UEC. The increase of IL-27 in uterine endometrial cancer cell (UECC) lines (Ishikawa, RL95-2 and KLE) led to a high cytotoxic activity of NK cells to UECC in the co-culture system. Exposure with rapamycin enhanced the cytotoxicity of NK cells by upregulating the expression of IL-27 in UECC and IL-27 receptors (IL-27Rs: WSX-1 and gp130) on NK cells and further restricted the growth of UEC in Ishikawa-xenografted nude mice. In addition, treatment with rapamycin resulted in an increased autophagy level of UECC, and IL-27 enhanced this ability of rapamycin. Cisplatin-mediated NK cells' cytotoxic activity and anti-UEC activation were independent of IL-27; however, the combination of rapamycin and cisplatin led to a higher cytotoxic activity of NK cells, smaller UEC volume and longer survival rate in vivo. These results suggest that rapamycin and cisplatin synergistically activate the cytotoxicity of NK cells and inhibit the progression of UEC in both an IL-27-dependent and independent manner. This provides a scientific basis for potential rapamycin cisplatin combined therapeutic strategies targeted to UEC, especially for the patients with low differentiated stage or abnormally low level of IL-27. PMID- 29195129 TI - Risk factors for crash involvement in older motorcycle riders. AB - A prospective cohort study was conducted to identify risk and protective factors for crash involvement in older motorcyclists. Over a 1-year study period from August 2013 to July 2014, study participants were recruited from local community centers of five cities in Taiwan. People aged >=60 years who rode a motorcycle at least once per week were eligible and were invited to participate in the study. Among 256 older riders who completed the baseline assessment and at least one of the four follow-up assessments, 79 (33.7%) experienced a motorcycle crash over the study period. Results of the proportional hazards model showed that after controlling for age, gender, and riding distance, older riders who had sustained hearing impairment (hazard ratio (HR)=2.58; 95% confidence interval (CI), 1.30 5.15), rode a motorcycle at speeds of >=41km/h (HR=2.31; 95% CI, 1.26-4.23), and had experienced a motorcycle crash in the past year (HR=1.81; 95% CI, 1.06-3.09) were more likely to be involved in a crash, compared to their counterparts. Conversely, older riders who were obese (HR=0.43; 95% CI, 0.22-0.82) were less likely to be involved in a crash than those with a normal weight, while longer functional reach distances (HR=0.96; 95% CI, 0.93-0.99) and higher Tinetti balance scores (HR=0.79; 95% CI, 0.69-0.91) were associated with a reduced risk of crash involvement. Among older people riding a motorcycle as their primary source of transportation, several factors associated with the occurrence of motorcycle crashes were identified. Restrictions and modifications of these risk factors may help design effective safety interventions for reducing crash and injury risks of this increasing riding population. PMID- 29195130 TI - Analyzing crash frequency in freeway tunnels: A correlated random parameters approach. AB - The majority of past road safety studies focused on open road segments while only a few focused on tunnels. Moreover, the past tunnel studies produced some inconsistent results about the safety effects of the traffic patterns, the tunnel design, and the pavement conditions. The effects of these conditions therefore remain unknown, especially for freeway tunnels in China. The study presented in this paper investigated the safety effects of these various factors utilizing a four-year period (2009-2012) of data as well as three models: 1) a random effects negative binomial model (RENB), 2) an uncorrelated random parameters negative binomial model (URPNB), and 3) a correlated random parameters negative binomial model (CRPNB). Of these three, the results showed that the CRPNB model provided better goodness-of-fit and offered more insights into the factors that contribute to tunnel safety. The CRPNB was not only able to allocate the part of the otherwise unobserved heterogeneity to the individual model parameters but also was able to estimate the cross-correlations between these parameters. Furthermore, the study results showed that traffic volume, tunnel length, proportion of heavy trucks, curvature, and pavement rutting were associated with higher frequencies of traffic crashes, while the distance to the tunnel wall, distance to the adjacent tunnel, distress ratio, International Roughness Index (IRI), and friction coefficient were associated with lower crash frequencies. In addition, the effects of the heterogeneity of the proportion of heavy trucks, the curvature, the rutting depth, and the friction coefficient were identified and their inter-correlations were analyzed. PMID- 29195131 TI - Motor priming by movement observation with contralateral concurrent action execution. AB - In the present study, the influence of simultaneous action execution on motor priming was investigated during movement observation using a simple-reaction task. Although previous studies have reported various effects of priming on motor performance, it has not yet been clarified how an additional source conveying kinetic information would modulate the priming effects. In the experiment, participants were asked to respond to an auditory cue by flexing their wrist while observing a line movement, which was slowly swinging like an inverted pendulum. In addition to the observation of line movement, the participants executed wrist flexion-extension actions synchronizing with line movement. The hand involved in pre-response wrist action varied with the priming condition: no movement execution (observation only), contralateral hand, and ipsilateral hand. In the contralateral condition, the stimulus-response congruency of movement direction was conflicted depending on the frame of reference (visual vs. anatomical coordinates). We found that all three priming conditions produced the compatibility effect, and the effect size did not differ between them. Importantly, in the contralateral condition, participants responded faster when the direction of line movement was congruent with the response movement in the anatomical coordinates. That is, the reaction time was shorter when pre-response action execution was in the flexion phase, even though the direction of observed movement and the response action were incongruent from the participants' view. These results suggest that kinetic information has a great contribution to the motor priming system, which can reverse the vision-based compatibility effect.

AB - The choroid plexus is able to modulate the cognitive function, through changes in the neuroinflammatory response and in brain immune surveillance. However, whether lycopene is involved in inflammatory responses at the choroid plexus in the early stages of Alzheimer's disease, and its molecular underpinnings are elusive. In this rat study, lycopene was used to investigate its protective effects on inflammation caused by beta-amyloid. We characterized the learning and memory abilities, cytokine profiles of circulating TNF-alpha, IL-1beta and IL-6beta in the serum and the expressions of Toll like receptor 4 and nuclear factor-kappaB p65 mRNA and protein at the choroid plexus. The results showed that functional deficits of learning and memory in lycopene treatment groups were significantly improved compared to the control group without lycopene treatment in water maze test. The levels of serum TNF-alpha, IL-1beta and IL-6beta were significantly increased, and the expressions of TLR4 and NF-kappaB p65 mRNA and protein at the choroid plexus were up-regulated, indicating inflammation response was initiated following administration of Abeta1-42. After intragastric pretreatment with lycopene, inflammatory cytokines were significantly reduced and lycopene also reversed the Abeta1-42 induced up-regulation of TLR4 and NF-kappaB p65 mRNA and protein expressions at the choroid plexus. These results provided a novel evidence that lycopene significantly improved cognitive deficits and were accompanied by the attenuation of inflammatory injury via blocking the activation of NF-kappaB p65 and TLR4 expressions and production of cytokines, thereby endorsing its usefulness for diminishing beta-amyloid deposition in the hippocampus tissues.

AB - Alpha and beta-glucoisosaccharinic acids ((2S,4S)-2,4,5-trihydroxy-2 (hydroxymethyl)pentanoic acid and (2R,4S)-2,4,5-trihydroxy-2 (hydroxymethyl)pentanoic acid) which are produced when cellulosic materials are treated with aqueous alkali are potentially valuable platform chemicals. Their highly functionalised carbon skeleton, with fixed chirality at C-2 and C-4, makes them ideal starting materials for use in synthesis. In order to assess the potential of these saccharinic acids as platform chemicals we have explored the protecting group chemistry of the lactone form of alpha-glucoisosaccharinic acid (alpha-GISAL). We report here the use of single and multiple step reaction pathways leading to the regioselective protection of the three different hydroxyl groups of alpha-GISAL. We report strategies for protecting the three different hydroxyl groups individually or in pairs. We also report the synthesis of a range of tri-O-protected alpha-GISAL derivatives where a number of the products contain orthogonal protecting groups.

AB - The long-chain n-3 polyunsaturated fatty acids (LC-PUFAs) eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) in fish oil have immunomodulatory properties. B cells are a poorly studied target of EPA/DHA in humans. Therefore, in this pilot study, we tested how n-3 LC-PUFAs influence B-cell responses of obese humans. Obese men and women were assigned to consume four 1-g capsules per day of olive oil (OO, n=12), fish oil (FO, n=12) concentrate or high-DHA-FO concentrate (n=10) for 12 weeks in a parallel design. Relative to baseline, FO (n=9) lowered the percentage of circulating memory and plasma B cells, whereas the other supplements had no effect. There were no postintervention differences between the three supplements. Next, ex vivo B-cell cytokines were assayed after stimulation of Toll-like receptors (TLRs) and/or the B-cell receptor (BCR) to determine if the effects of n-3 LC-PUFAs were pathway-dependent. B-cell IL-10 and TNFalpha secretion was respectively increased with high DHA-FO (n=10), relative to baseline, with respective TLR9 and TLR9+BCR stimulation. OO (n=12) and FO (n=12) had no influence on B-cell cytokines compared to baseline, and there were no differences in postintervention cytokine levels between treatment groups. Finally, ex vivo antibody levels were assayed with FO (n=7) after TLR9+BCR stimulation. Compared to baseline, FO lowered IgM but not IgG levels accompanied by select modifications to the plasma lipidome. Altogether, the results suggest that n-3 LC-PUFAs could modulate B-cell activity in humans, which will require further testing in a larger cohort. PMID- 29195135 TI - Urinary metabolites of organophosphate esters: Concentrations and age trends in Australian children. AB - There is growing concern around the use of organophosphate esters (OPEs) due to their suspected reproductive toxicity, carcinogenicity, and neurotoxicity. OPEs are used as flame retardants and plasticizers, and due to their extensive application in consumer products, are found globally in the indoor environment. Early life exposure to OPEs is an important risk factor for children's health, but poorly understood. To study age and sex trends of OPE exposures in infants and young children, we collected, pooled, and analysed urine samples from children aged 0-5years from Queensland, Australia for 9 parent OPEs and 11 metabolites. Individual urine samples (n=400) were stratified by age and sex, and combined into 20 pools. Three individual breast milk samples were also analysed to provide a preliminary estimate on the contribution of breast milk to the intake of OPEs. Bis(1-chloroisopropyl) phosphate (BCIPP), 1-hydroxy-2-propyl bis(1-chloro-2-propyl) phosphate (BCIPHIPP), bis(1,3-dichloroisopropyl) phosphate (BDCIPP), dibutyl phosphate (DBP), diphenyl phosphate (DPHP), bis(2-butoxyethyl) phosphate (BBOEP), bis(2-butoxyethyl) 3-hydroxyl-2-butoxyethyl phosphate (3OH TBOEP), and bis(2-butoxyethyl) hydroxyethyl phosphate (BBOEHEP) were detected in all urine samples, followed by bis(methylphenyl) phosphate (80%), and bis(2 ethylhexyl) phosphate (BEHP, 20%), and bis(2-chloroethyl) phosphate (BCEP, 15%). Concentrations of tris(2-chloroethyl) phosphate (TCEP), BCEP, tris(2-ethylhexyl) phosphate (TEHP), and DBP decreased with age, while bis(methylphenyl) phosphate (BMPP) increased with age. Significantly higher concentrations of DPHP (p=0.039), and significantly lower concentrations of TEHP (p=0.006) were found in female samples compared to males. The estimated daily intakes (EDIs) via breastfeeding, were 4.6, 26 and 76ng/kg/day for TCEP, TBP and TEHP, respectively, and were higher than that via air and dust, suggesting higher exposure through consumption of breast milk. PMID- 29195138 TI - Mechanisms of head stability during gait initiation in young and older women: A neuro-mechanical analysis. AB - Decreased head stability has been reported in older women during locomotor transitions such as the initiation of gait. The aim of the study was to investigate the neuro-mechanical mechanisms underpinning head stabilisation in young and older women during gait initiation. Eleven young (23.1 +/- 1.1 yrs) and 12 older (73.9 +/- 2.4 yrs) women initiated walking at comfortable speed while focussing on a fixed visual target at eye level. A stereophotogrammetric system was used to assess variability of angular displacement and RMS acceleration of the pelvis, trunk and head, and dynamic stability in the anteroposterior and mediolateral directions. Latency of muscle activation in the sternocleidomastoid, and upper and lower trunk muscles were determined by surface electromyography. Older displayed higher variability of head angular displacement, and a decreased ability to attenuate accelerations from trunk to head, compared to young in the anteroposterior but not mediolateral direction. Moreover, older displayed a delayed onset of sternocleidomastoid activation than young. In conclusion, the age-related decrease in head stability could be attributed to an impaired ability to attenuate accelerations from trunk to head along with delayed onset of neck muscles activation. PMID- 29195136 TI - Oxidized LDL triggers changes in oxidative stress and inflammatory biomarkers in human macrophages. AB - Oxidized low-density lipoprotein (oxLDL) is a well-recognized proatherogenic particle that functions in atherosclerosis. In this study, we established conditions to generate human oxLDL, characterized according to the grade of lipid and protein oxidation, particle size and oxylipin content. The induction effect of the cellular proatherogenic response was assessed in foam cells by using an oxLDL-macrophage interaction model. Uptake of oxLDL, reactive oxygen species production and expression of oxLDL receptors (CD36, SR-A and LOX-1) were significantly increased in THP-1 macrophages. Analyses of 35 oxylipins revealed that isoprostanes (IsoP) and prostaglandins (PGs) derived from the oxidation of arachidonic, dihomo gamma-linolenic and eicosapentaenoic acids were strongly and significantly induced in macrophages stimulated with oxLDL. Importantly, the main metabolites responsible for the THP1-macrophage response to oxLDL exposure were the oxidative stress markers 5-epi-5-F2t-IsoP, 15-E1t-IsoP, 8-F3t-IsoP and 15 keto-15-F2t-IsoP as well as inflammatory markers PGDM, 17-trans-PGF3alpha, and 11beta-PGF2alpha, all of which are reported here, for the first time, to function in the interaction of oxLDL with THP-1 macrophages. By contrast, a salvage pathway mediated by anti-inflammatory PGs (PGE1 and 17-trans-PGF3alpha) was also identified, suggesting a response to oxLDL-induced injury. In conclusion, when THP-1 macrophages were treated with oxLDL, a specific induction of biomarkers related to oxidative stress and inflammation was triggered. This work contributes to our understanding of initial atherogenic events mediated by oxLDL-macrophage interactions and helps to generate new approaches for their modulation. PMID- 29195137 TI - The NADPH organizers NoxO1 and p47phox are both mediators of diabetes-induced vascular dysfunction in mice. AB - AIM: NADPH oxidases are important sources of reactive oxygen species (ROS). Several Nox homologues are present together in the vascular system but whether they exhibit crosstalk at the activity level is unknown. To address this, vessel function of knockout mice for the cytosolic Nox organizer proteins p47phox, NoxO1 and a p47phox-NoxO1-double knockout were studied under normal condition and during streptozotocin-induced diabetes. RESULTS: In the mouse aorta, mRNA expression for NoxO1 was predominant in smooth muscle and endothelial cells, whereas p47phox was markedly expressed in adventitial cells comprising leukocytes and tissue resident macrophages. Knockout of either NoxO1 or p47phox resulted in lower basal blood pressure. Deletion of any of the two subunits also prevented diabetes-induced vascular dysfunction. mRNA expression analysis by MACE (Massive Analysis of cDNA ends) identified substantial gene expression differences between the mouse lines and in response to diabetes. Deletion of p47phox induced inflammatory activation with increased markers of myeloid cells and cytokine and chemokine induction. In contrast, deletion of NoxO1 resulted in an attenuated interferon gamma signature and reduced expression of genes related to antigen presentation. This aspect was also reflected by a reduced number of circulating lymphocytes in NoxO1-/- mice. INNOVATION AND CONCLUSION: ROS production stimulated by NoxO1 and p47phox limit endothelium-dependent relaxation and maintain blood pressure in mice. However, NoxO1 and p47phox cannot substitute each other despite their similar effect on vascular function. Deletion of NoxO1 induced an anti-inflammatory phenotype, whereas p47phox deletion rather elicited a hyper-inflammatory response.

AB - Resolution in scanning transmission electron microscopy (STEM) is ultimately limited by the diameter of the electron beam. The electron beam diameter is not only determined by the properties of the condenser lens system but also by electron scattering in the specimen which leads to electron-beam broadening and degradation of the resolution with increasing specimen thickness. In this work we introduce a new method to measure electron-beam broadening which is based on STEM imaging with a multi-segmented STEM detector. We focus on STEM at low electron energies between 10 and 30 keV and use an amorphous carbon film with known thickness as test object. The experimental results are compared with calculated beam diameters using different analytical models and Monte-Carlo simulations. We find excellent agreement of the experimental data with the recently published model by Gauvin and Rudinsky [1] for small t/lambdael (thickness to elastic mean free path) values which are considered in our study. PMID- 29195140 TI - Are the decrease in circulating anti-alpha1,3-Gal IgG and the lower content of galactosyl transferase A1 in the microbiota of patients with multiple sclerosis a novel environmental risk factor for the disease? AB - The etiology of multiple sclerosis (MS), particularly the environmental component of the disease, remains speculative. Recent reports have suggested that alterations in the gut microbiota of MS patients could contribute to the etiology or pathophysiology of the disease. In this Viewpoint, using PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States) to infer the functional content of the gut microbiota, we show that the gut microbiota of MS patients is characterized by a significant decrease in the relative abundance of the enzyme EC 2.4.1.87, which corresponds to the GGTA1 gene (which codes for the alpha1,3-Gal epitope and is lacking in humans), against which MS patients also have low levels of IgG antibodies. The decrease in circulating anti-alpha1,3-Gal IgG and lower content of galactosyl transferase A1 in the microbiota of patients with multiple sclerosis could be a novel environmental risk factor for the disease. PMID- 29195142 TI - Quantification of glycerophospholipids and sphingomyelin in human milk and infant formula by high performance liquid chromatography coupled with mass spectrometer detector. AB - Phospholipids and sphingomyelin have a central role in infant nutrition, phospholipid acting as a nutrient carrier of long chain polyunsaturated fatty acids and sphingomyelin having an important role in cognitive function. However, analytical methods to precisely characterize and quantify these compounds in maternal milk are needed. Phospholipids and sphingomyelin were extracted using chloroform and methanol and separated on Polaris 3 Si column 250*2.0mm from Varian and analyzed by high performance liquid chromatography (HPLC) coupled with mass spectrometer detector (MS). The analytical method was validated and repeatability, intermediate reproducibility, and recovery values were calculated. The relative standard deviation of repeatability (CV(r)) and intermediate reproducibility (CV(iR)) values ranged between 2.3 and 7.2% and 9.5 and 17.8%, respectively and the recovery values between 96 and 109%. Finally, the validated method was tested on human milk samples and on infant formula which were analysed also by HPLC coupled with evaporative light scattering detector (ELSD). In human milk, sphingomyelin (9.28mg100mL-1) was the most abundant compound, followed by phosphatidylcholine (5.39mg100mL-1), phosphatidylethanolamine (2.85mg100mL-1) and phosphatidylinositol (1.82mg100mL-1). PMID- 29195141 TI - IL-17 is a protection effector against the adherent-invasive Escherichia coli in murine colitis. AB - Inflammatory bowel disease (IBD) is caused by aberrant immune responses to the gut microbiota. Among the gut microbiota, adherent-invasive Escherichia Coli (AIEC) is thought to be the pathogen through invading the intestinal epithelial cells and causing inflammation. IL-17 secretion increase, induced by enhanced bacterial adhesion to the intestine epithelium, could on one hand protect the mucosa, but on the other hand, over amount of IL-17 initializes inflammation reactions that in turn damages the mucosa. The relationship between IL-17 and AIEC is still unclear. In this study, we tried to elucidate the function of IL-17 in AIEC-mediated colitis. Wild type (WT) and IL-17 knockout (IL-17 KO) mice were inoculated with AIEC strain E. coli LF82 and treated with dextran sodium sulphate (DSS). Histological examination of the colon was performed. Mucosa damage was assessed and scored. IL-22 and IL-17 in colon tissues were detected by ELISA, qPCR and immunohistochemistry methods. Transient AIEC colonization in IL-17 KO mice resulted in increased intestinal epithelial damage, systemic bacterial burden and mortality compared with WT controls. Moreover, IL-17 is required for the induction of IL-22 in the experimental animal models during AIEC strain E. coli LF82 colonization. These results indicate IL-17 plays a protective role in AIEC strain E. coli LF82 induced colitis by promoting IL-22 secretion. PMID- 29195143 TI - Metabolite identification and pharmacokinetic profiling of PP242, an ATP competitive inhibitor of mTOR using ultra high-performance liquid chromatography and mass spectrometry. AB - PP242 is a second generation novel selective ATP-competitive inhibitor of mTOR that displayed promising anti-cancer activity over several cancer types by inhibiting both the complexes of mTOR (mTORC1 and mTORC2). The purpose of this study is to identify the possible metabolites and to evaluate the pharmacokinetic profile of PP242 after a single oral administration to Sprague-Dawley (SD) rats. Two metabolites, including one phase I and one phase II, were identified by in vitro and in vivo studies using rat liver microsomes (RLMs) as well as rat plasma, urine and feces, respectively, through ultra high-performance liquid chromatography-linear ion trap quadrupole-orbitrap-mass spectrometry (UHPLC-LTQ Orbitrap-MS). The major biotransformation pathways of PP242 were hydroxylation and glucuronide conjugation. Additionally, a simple and rapid quantification method was developed and validated. The method recovery was within 79.7-84.6%, whereas the matrix effect was 78.1-96.0% in all three quality control (QC) concentrations (low, medium and high) including the LLOQ. Other parameters showed acceptable results according to the US food and drug administration (FDA) guidelines for bioanalytical method validation. Afterwards, pharmacokinetic parameters were evaluated in rat plasma by successfully applying the validated method using liquid chromatography-tandem mass spectrometry (LC-MS/MS). After a single oral administration at a dose of 5mg/kg, the maximum plasma concentration (Cmax) of PP242 was 0.17+/-0.08MUg/mL, while the elimination was moderately fast (T1/2: 172.18+/-45.54min). All of the obtained information on the metabolite identification and pharmacokinetic parameter elucidation could facilitate the further development of PP242. PMID- 29195144 TI - Quantification of amlodipine in dried blood spot samples by high performance liquid chromatography tandem mass spectrometry. AB - A sensitive and specific method, utilising high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) was developed for the quantitative determination of amlodipine in dried blood spot (DBS) samples. Chromatographic separation was achieved using a Waters XBridge C18 column with gradient elution of a mixture of water and acetonitrile containing 0.1% formic acid (v/v). Amlodipine was quantified using a Waters Quattro Premier mass spectrometer coupled with an electro-spray ionization (ESI) source in positive ion mode. The MRM transitions of 408.9 m/z->238.1m/z and 408.9->294.0 m/z were used to quantify and qualify amlodipine, respectively. The method was validated across the concentration range of 0.5-30ng/mL by assessing specificity, sensitivity, linearity, precision, accuracy, recovery and matrix effect according to the Food and Drug Administration (FDA) guidelines. This method was also validated clinically within a large pharmacoepidemiological study in which amlodipine blood concentration was determined in patients who had been prescribed this medication. PMID- 29195145 TI - Simultaneous quantification of succinylacetone and nitisinone for therapeutic drug monitoring in the treatment of Tyrosinemia type 1. AB - We present a straightforward and robust method for simultaneous quantification of succinylacetone and nitisinone in plasma using LC-ESI-MS/MS. The method has been developed for routine therapeutic drug monitoring in hepatorenal tyrosinemia type 1 (HT1) patients undergoing nitisinone treatment. Previous methods are based on separate analyses of succinylacetone and nitisinone, often using the potentially harmful compound hydrazine for derivatization of the former. In the present procedure, succinylacetone is derivatized in a single-step using butanolic HCl. Analyte extraction and sample clean-up is carried out by simple protein precipitation. The linear range for both analytes is 0.1 up to 125MUM, covering the vast majority of encountered levels in real-life samples. The sensitivity and limit of quantification allows measurement of succinylacetone in the therapeutical range for HT1 patients. Stability studies show that succinylacetone is highly sensitive to storage conditions, whereas nitisinone shows little to no degradation. Correct sample handling is therefore important for reliable results when monitoring succinylacetone concentrations. PMID- 29195146 TI - Fast and quantitative determination of saxitoxin and neosaxitoxin in urine by ultra performance liquid chromatography-triple quadrupole mass spectrometry based on the cleanup of solid phase extraction with hydrophilic interaction mechanism. AB - Saxitoxin (STX) and neosaxitoxin (NEO) are water-soluble toxins and their cleanup in bio-matrix is a hot topic but difficult problem. A fast and quantitative determination method for STX and NEO in urine was developed using ultra performance liquid chromatography-triple quadrupole mass spectrometry (LC-MS/MS) based on the cleanup of solid phase extraction (SPE) with hydrophilic interaction (HILIC) mechanism. Acetonitrile/methanol/water mixture was used to extract the toxins in urine. Polyamide (PA) was used as HILIC SPE material to clean the toxins in sample matrix. The limits of detection were 0.2ngmL-1 for STX and 1ngmL 1 for NEO in urine. The linear ranges were 0.5ngmL-1-99.2ngmL-1 with the correlation coefficient of r=0.9992 for STX and 2.1ngmL-1-207ngmL-1 with r=0.997 for NEO in urine matrix. The recoveries at three spiking levels were 81.5%-117% with the relative standard deviations (RSDs) of 5.4%-8.5% for STX and 89.0%-118% with the RSDs of 6.7%-9.1% for NEO. STX was found in all the 6 patients' urines while NEO was only found in one sample from an intoxication case. PMID- 29195147 TI - Young adult e-cigarette use outcome expectancies: Validity of a revised scale and a short scale. AB - The revised youth e-cigarette outcome expectancies measure adds new items informed by recent qualitative research with young adult e-cigarette users, especially in the domain of positive "smoking" experience. Positive "smoking" experience represents beliefs that use of e-cigarettes provides outcomes associated with a better "smoking" alternative: for example, an alternative that is more socially approved, more suitable for indoor use, and that provides a safer means of enjoying nicotine. In addition, we tested a short, 8-item version of the measure which may be more easily incorporated into surveys. We tested the validity of the revised measure, both long and short versions, in terms of factor structure and associations of the expectancy factors with current e-cigarette use, e-cigarette use susceptibility, and e-cigarette use dependence. Participants were young adults (N=470; 65% women; mean age=20.9, SD=2.1). Results replicated the findings of the previous study as well as highlighted the importance of the added domain of positive "smoking" experience and the validity of the short scale. Furthermore, results showed that positive outcome expectancies are strongly associated with e-cigarette use dependence. The long and short versions of the revised youth e-cigarette outcome expectancies scale appear to be valid and useful for application not only among cigarette smokers and e-cigarette users but also among never smokers and never e-cigarette users. PMID- 29195148 TI - When do arrows start to compete? A developmental mouse-tracking study. AB - Recent work in adults has suggested that the strength of social and symbolic cues not presented at fixation (but allowing eye movements to the cue) may be determined less by their biological relevance and more by the distinctiveness of the shape of the cue. The present study examines whether these results extend to children, who may differ in their relative exposure to symbolic cues (arrows) compared to social cues. Children aged 3 to 11 were presented with congruent or incongruent pairs of cues (line drawings of gazing eyes, pointing hands, and arrows) and were asked to indicate the direction of the target cue (indicated at the start of the block) by moving the mouse towards the response box indicating its direction. Results show a similar advantage for arrows and pointing hands in young children as previously found in adults, suggesting that cue shape trumps biological relevance for cues away from fixation from an early age. PMID- 29195149 TI - Enhanced production of biosynthesized lycopene via heterogenous MVA pathway based on chromosomal multiple position integration strategy plus plasmid systems in Escherichia coli. AB - The multiple plasmid system, mostly relied, for heterogeneous gene expression, results in genetic instability and low mean productivity. To address this, an integration method was employed for investigating expression of heterogenous pathway in E. coli cells; where mevalonate upper pathway was found efficiently expressed. Subsequently, to improve lycopene production, chromosomal multiple position integration strategy was used to strengthen mevalonate upper pathway. Meanwhile, the plasmid system was employed for mevalonate lower pathway and lycopene pathway expression to finally generate the mutant D711 strain. Comparatively, highest level of 68.5 mg/L lycopene was produced by D711 outperforming its maximum average productivity of 2.85 mg/L/h with over 2-folds enhancement. In addition, lycopene level was almost 224 mg/L after optimization of induction time, which was 3.3-fold higher than standard control condition. Finally, expression Performance Parameter was developed for scoring mutants and evaluating these two strategies, indicating chromosomal multiple position integration strategy as more efficient approach. PMID- 29195150 TI - Effect of different ammonia sources on aceticlastic and hydrogenotrophic methanogens. AB - Ammonium chloride (NH4Cl) was usually used as a model ammonia source to simulate ammonia inhibition during anaerobic digestion (AD) of nitrogen-rich feedstocks. However, ammonia in AD originates mainly from degradation of proteins, urea and nucleic acids, which is distinct from NH4Cl. Thus, in this study, the inhibitory effect of a "natural" ammonia source (urea) and NH4Cl, on four pure methanogenic strains (aceticlastic: Methanosarcina thermophila, Methanosarcina barkeri; hydrogenotrophic: Methanoculleus bourgensis, Methanoculleus thermophilus), was assessed under mesophilic (37 degrees C) and thermophilic (55 degrees C) conditions. The results showed that urea hydrolysis increased pH significantly to unsuitable levels for methanogenic growth, while NH4Cl had a negligible effect on pH. After adjusting initial pH to 7 and 8, urea was significantly stronger inhibitor with longer lag phases to methanogenesis compared to NH4Cl. Overall, urea seems to be more toxic on both aceticlastic and hydrogenotrophic methanogens compared to NH4Cl under the same total and free ammonia levels. PMID- 29195151 TI - Membrane fouling mechanism of biofilm-membrane bioreactor (BF-MBR): Pore blocking model and membrane cleaning. AB - Biofilm membrane bioreactor (BF-MBR) is considered as an important wastewater treatment technology that incorporates advantages of both biofilm and MBR process, as well as can alleviate membrane fouling, with respect to the conventional activated sludge MBR. But, to be efficient, it necessitates the establishment of proper methods for the assessment of membrane fouling. Four Hermia membrane blocking models were adopted to quantify and evaluate the membrane fouling of BF-MBR. The experiments were conducted with various operational conditions, including membrane types, agitation speeds and transmembrane pressure (TMP). Good agreement between cake formation model and experimental data was found, confirming the validity of the Hermia models for assessing the membrane fouling of BF-MBR and that cake layer deposits on membrane. Moreover, the influences of membrane types, agitation speeds and transmembrane pressure on the Hermia pore blocking coefficient of cake layer were investigated. In addition, the permeability recovery after membrane cleaning at various operational conditions was studied. This work confirms that, unlike conventional activated sludge MBR, BF-MBR possesses a low degree of membrane fouling and a higher membrane permeability recovery after cleaning. PMID- 29195152 TI - d-1,2,4-Butanetriol production from renewable biomass with optimization of synthetic pathway in engineered Escherichia coli. AB - Bio-based production of d-1,2,4-butanetriol (BT) from renewable substrates is increasingly attracting attention. Here, the BT biosynthetic pathway was constructed and optimized in Escherichia coli to produce BT from pure d-xylose or corncob hydrolysates. First, E. coli BL21(DE3) was identified as a more proper host for BT production through host screening. Then, BT pathway was systematically optimized with gene homolog screening strategy, mainly targeting three key steps from xylonic acid to BT catalyzed by d-xylonate dehydratase (XD), 2-keto acid decarboxylase (KDC) and aldehyde reductase (ALR). After screening six ALRs, four KDCs and four XDs, AdhP from E. coli, KdcA from Lactococcus lactis and XylD from Caulobacter crescentus were identified more efficiently for BT production. The co-expression of these enzymes in recombinant strain BL21-14 led to BT production of 5.1 g/L under the optimized cultivation conditions. Finally, BT production from corncob hydrolysates was achieved with a titer of 3.4 g/L. PMID- 29195153 TI - Composition characterization and transformation mechanism of refractory dissolved organic matter from an ANAMMOX reactor fed with mature landfill leachate. AB - This study applied combined spectroscopy techniques to assess rDOM compositional characteristic and investigated its transformation mechanisms during the treatment of mature landfill leachate by ANAMMOX process. A novel rDOM metabolism mechanism was proposed in this study for the first time. A stable, high nitrogen removal rate of 5.95 kg N/m3/day and a rDOM conversion efficiency of 51% were achieved in ANAMMOX reactor (AR). In additionally, the initial rDOM removal was closely related to sludge adsorption, with the adsorption force mainly originating from electrostatic interaction and hydrophobicity. As the operating time increased, the removal mechanism of rDOM in the AR changed from adsorption to adsorption-biodegradation and finally stabilized. Furthermore, Anaerolineaceae, associated with the hydrophobic reaction, were the primary degraders for the rDOM and Candidatus Kuenenia dominated the nitrogen consumption. rDOM removal efficiency was suggested to be increased by a moderate enhancement of Anaerolineaceae content in the AR. PMID- 29195154 TI - Pyrolysis kinetics and thermodynamic parameters of castor (Ricinus communis) residue using thermogravimetric analysis. AB - Castor plant is a fast-growing, perennial shrub from Euphorbiaceae family. More than 50% of the residue is generated from its stems and leaves. The main aim of this work is to study the pyrolytic characteristics, kinetics and thermodynamic properties of castor residue. The TGA experiments were carried out from room temperature to 900 degrees C under an inert atmosphere at different heating rates of 5, 10, 15, 20, 30 and 40 degrees C/min. The kinetic analysis was carried using different models namely Kissinger, Flynn-Wall-Ozawa (FWO) and Kissinger-Akahira-Sunose (KAS). The average Ealpha calculated by FWO and KAS methods were 167.10 and 165.86 kJ/mole respectively. Gibbs free energy varied from 150.62-154.33 to 150.59-154.65 kJ/mol for FWO and KAS respectively. The HHV of castor residue was 14.43 MJ/kg, considered as potential feedstock for bio energy production. Kinetic and thermodynamic results will be useful input for the design of pyrolytic process using castor residue as feedstock. PMID- 29195155 TI - Complex effect of lignocellulosic biomass pretreatment with 1-butyl-3 methylimidazolium chloride ionic liquid on various aspects of ethanol and fumaric acid production by immobilized cells within SSF. AB - The pretreatment of softwood and hardwood samples (spruce and hornbeam wood) with 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) was undertaken for further simultaneous enzymatic saccharification of renewable non-food lignocellulosic biomass and microbial fermentation of obtained sugars to ethanol and fumaric acid. A multienzyme cocktail based on cellulases and yeast or fungus cells producing ethanol and fumaric acid were the main objects of [Bmim]Cl influence studies. A complex effect of lignocellulosic biomass pretreatment with [Bmim]Cl on various aspects of the process (both action of cellulases and microbial conversion of hydrolysates to target products) was revealed. Positive effects of the pretreatment with [Bmim]Cl included decreasing the lignin content in the biomass, and increasing the effectiveness of enzymatic hydrolysis and microbial transformation of pretreated biomass. Immobilized cells of both yeasts and fungi possessed improved productive characteristics in the biotransformation of biomass pretreated with [Bmim]Cl to ethanol and fumaric acid. PMID- 29195156 TI - The transformation from anammox granules to deammonification granules in micro aerobic system by facilitating indigenous ammonia oxidizing bacteria. AB - Granular deammonification process is a good way to retain aerobic and anaerobic ammonia oxidizing bacteria (AOB and anammox bacteria) and exhaust flocculent nitrite oxidizing bacteria (NOB). In this study, to facilitate indigenous AOB growth on anammox granules, by stepwise reducing influent nitrite, anammox granules were effectively transformed into deammonification granules in a micro aerobic EGSB in 100 days. Total nitrogen removal efficiency of 90% and nitrogen removal rate of 2.3 g N/L/d were reached at stable deammonification stage. High influent FA and limited oxygen supply contributed suppression for Nitrospira-like NOB. In transition stages, Proteobacteria and Chloroflexi were always dominated. Anammox abundance decreased, while AOB abundance grew fast. Anammox bacteria and AOB were dominated by Brocadia fulgida and Nitrosomonas europaea, respectively. Denitrification activity and bacteria existed although without influent organic. The final AOB abundance was about 4.55-13.8 times more than anammox bacteria abundance, with almost equal potential activities.

AB - BACKGROUND: Targeting the frequency or complexity of prelinguistic vocalizations might improve the language trajectory of children with autism spectrum disorder (ASD) who exhibit continued expressive language deficits. AIMS: This meta analysis evaluates the strength of the association between various measures of vocalizations and expressive language in young children with ASD and five putative moderators of that association to inform prelinguistic intervention development: consonant-centricity, communicativeness, concurrent versus longitudinal research design, risk for correlated measurement error, and publication status. METHODS AND PROCEDURES: We systematically searched databases and other sources for correlations between vocalizations and expressive language in children with ASD less than 9 years old. Using robust variance estimation, we calculated the weighted mean effect size and conducted moderator analyses. OUTCOMES AND RESULTS: Nine studies (19 reports), which included 362 participants and 109 unique effect sizes, met inclusion criteria. The weighted mean effect size between vocalizations and expressive language was significant (r=0.50, 95% CI [0.23, 0.76]). As predicted, concurrent correlations were significantly stronger than longitudinal correlations. Other moderator effects were not detected. CONCLUSIONS AND IMPLICATIONS: Young children with ASD demonstrate a strong association between vocalizations and expressive language skills. Future experimental studies should investigate causal relations to guide intervention development.

AB - While a compelling body of behavioral research suggests that individuals with developmental coordination disorder (DCD) experience difficulties engaging motor imagery (MI), very little is known about the neural correlates of this deficit. Since corticospinal excitability is a predictor of MI proficiency in healthy adults, we reasoned that decreased MI efficiency in DCD may be paralleled by atypical primary motor cortex (PMC) activity. Participants were 29 young adults aged 18- 36 years: 8 with DCD (DCD) and 21 controls. Six participants with DCD and 15 controls showed behavioral profiles consistent with the use of a MI strategy (MI users) while performing a novel adaptation of the classic hand laterality task (HLT). Single-pulse transcranial magnetic stimulation (TMS) was administered to the hand node of the left PMC (hPMC) at 50ms, 400ms or 650ms post stimulus presentation during the HLT. Motor-evoked potentials (MEPs) were recorded from the right first dorsal interosseous (FDI) via electromyography. As predicted, MI users with DCD were significantly less efficient than MI using controls, shown by poorer performance on the HLT. Importantly, unlike healthy controls, no evidence of enhanced hPMC activity during MI was detected in our DCD group. Our data are consistent with the view that inefficient MI in DCD may be subserved by decreased hPMC activity. These findings are an important step towards clarifying the neuro-cognitive correlates of poor MI ability and motor skill in individuals with DCD.

AB - To demonstrate the effectiveness of UV light-emitting diodes (UV-LEDs) to disinfect water, UV-LEDs at peak emission wavelengths of 265, 280, and 300 nm were adopted to inactivate pathogenic species, including Pseudomonas aeruginosa and Legionella pneumophila, and surrogate species, including Escherichia coli, Bacillus subtilis spores, and bacteriophage Qbeta in water, compared to conventional low-pressure UV lamp emitting at 254 nm. The inactivation profiles of each species showed either a linear or sigmoidal survival curve, which both fit well with the Geeraerd's model. Based on the inactivation rate constant, the 265-nm UV-LED showed most effective fluence, except for with E. coli which showed similar inactivation rates at 265 and 254 nm. Electrical energy consumption required for 3-log10 inactivation (EE,3) was lowest for the 280-nm UV-LED for all microbial species tested. Taken together, the findings of this study determined the inactivation profiles and kinetics of both pathogenic bacteria and surrogate species under UV-LED exposure at different wavelengths. We also demonstrated that not only inactivation rate constants, but also energy efficiency should be considered when selecting an emission wavelength for UV-LEDs. PMID- 29195160 TI - Modulation of the anticonvulsant effect of swim stress by agmatine. AB - Agmatine is an endogenous l-arginine metabolite with neuroprotective effects in the stress-response system. It exerts anticonvulsant effects against several seizure paradigms. Swim stress induces an anticonvulsant effect by activation of endogenous antiseizure mechanisms. In this study, we investigated the interaction of agmatine with the anticonvulsant effect of swim stress in mice on pentylenetetrazole (PTZ)-induced seizure threshold. Then we studied the involvement of nitric oxide (NO) pathway and endogenous opioid system in that interaction. Swim stress induced an anticonvulsant effect on PTZ seizures which was opioid-independent in shorter than 1-min swim durations and opioid-dependent with longer swims, as it was completely reversed by pretreatment with naltrexone (NTX) (10mg/kg), an opioid receptor antagonist. Agmatine significantly enhanced the anticonvulsant effect of opioid-independent shorter swim stress, in which a combination of subthreshold swim stress duration (45s) and subeffective dose of agmatine (1mg/kg) revealed a significantly higher seizure threshold compared with either one. This effect was significantly reversed by NO synthase inhibitor NG nitro-l-arginine (L-NAME (Nomega-Nitro-L-arginine methyl ester), 5mg/kg), suggesting an NO-dependent mechanism, and was unaffected by NTX (10mg/kg), proving little role for endogenous opioids in the interaction. Our data suggest that pretreatment of animals with agmatine acts additively with short swim stress to exert anticonvulsant responses, possibly by mediating NO pathway. PMID- 29195161 TI - Prenatal and pubertal testosterone affect brain lateralization. AB - After decades of research, the influence of prenatal testosterone on brain lateralization is still elusive, whereas the influence of pubertal testosterone on functional brain lateralization has not been investigated, although there is increasing evidence that testosterone affects the brain in puberty. We performed a longitudinal study, investigating the relationship between prenatal testosterone concentrations in amniotic fluid, pubertal testosterone concentrations in saliva, and brain lateralization (measured with functional Transcranial Doppler ultrasonography (fTCD)) of the Mental Rotation, Chimeric Faces and Word Generation tasks. Thirty boys and 30 girls participated in this study at the age of 15 years. For boys, we found a significant interaction effect between prenatal and pubertal testosterone on lateralization of Mental Rotation and Chimeric Faces. In the boys with low prenatal testosterone levels, pubertal testosterone was positively related to the strength of lateralization in the right hemisphere, while in the boys with high prenatal testosterone levels, pubertal testosterone was negatively related to the strength of lateralization. For Word Generation, pubertal testosterone was negatively related to the strength of lateralization in the left hemisphere in boys. For girls, we did not find any significant effects, possibly because their pubertal testosterone levels were in many cases below quantification limit. To conclude, prenatal and pubertal testosterone affect lateralization in a task-specific way. Our findings cannot be explained by simple models of prenatal testosterone affecting brain lateralization in a similar way for all tasks. We discuss alternative models involving age dependent effects of testosterone, with a role for androgen receptor distribution and efficiency. PMID- 29195162 TI - Effects of adolescent social stress and antidepressant treatment on cognitive inflexibility and Bdnf epigenetic modifications in the mPFC of adult mice. AB - Adolescent social stress (ASS) can increase susceptibility to depression in adulthood. However, the underlying psychological and neural mechanisms remain unclear. Cortically mediated cognitive dysfunctions are increasingly recognized as an independent and important risk factor of depression. Using social defeat stress, a classical animal model of depression, our previous studies found that mice subjected to this form of stress during early adolescence displayed cognitive inflexibility (CI) in adulthood. This change was accompanied by a down regulation of Bdnf gene expression in the medial prefrontal cortex (mPFC); this gene encodes a key molecule involved in depression and antidepressant action. In the present paper, we identified epigenetic modification of Bdnf as a possible mechanism underlying the behavioral and molecular changes. ASS induced a set of depressive phenotypes, including increased social avoidance and CI, as well as reduced levels of total Bdnf and isoform IV but not isoform I or VI transcripts in the mPFC. In parallel with changes in Bdnf gene expression, previously stressed adult mice showed increased levels of dimethylation of histone H3 at lysine K9 (H3K9me2) immediately downstream of the Bdnf IV promoter. On the other hand, no differences were found in trimethylation of histone H3 at lysine K4 (H3K4me3) or in acetylation of histone H3 at lysine K9 (H3K9ac) or at K4 (H3K4ac) in the Bdnf IV promoter. Likewise, no alterations were found in DNA methylation of the Bdnf IV promoter. Additionally, treatment with the chronic antidepressant tranylcypromine reversed Bdnf epigenetic changes and related gene transcription while also reversing CI, but not social avoidance, in previously stressed adult mice. These results suggest that epigenetic changes to the Bdnf gene in the mPFC after adolescent social adversity may be involved in the regulation of cognitive dysfunction in depression and antidepressant action in adulthood. PMID- 29195163 TI - Environmental impacts of heavy metals, rare earth elements and natural radionuclides in marine sediment from Ras Tanura, Saudi Arabia along the Arabian Gulf. AB - Ras Tanura city is one of the most important cities in Saudi Arabia because of the presence of the largest and oldest oil refinery in the Middle East which was began operations in September 1945. Also its contains gas plant and two ports. The concentration of natural radionuclides, heavy metals and rare earth elements were measured in marine sediment samples collected from Ras Tanura. The specific activities of 238U, 226Ra, 232Th, 40K and 137Cs (Bq/kg) were measured using A hyper-pure Germanium detector (HPGe), and ranged from (20.4 +/- 4.0-55.1 +/- 9.9), (6.71 +/- 0.7-46.1 +/- 4.5), (3.51 +/- 0.5-18.2 +/- 1.5), (105 +/- 4.4-492 +/- 13) and from (0.33 +/- 0.04-2.10 +/- 0.4) for 238U, 226Ra, 232Th, 40K and 137Cs respectively. Heavy metals and rare earth elements were measured using ICPE 9820 Plasma Atomic Emission Spectrometer. Also the frequency distributions for all radioactive variables in sediment samples were analyzed. Finally the radiological hazards due to natural radionuclides in marine sediment were calculated to the public and it's diagramed by Surfer program in maps. Comparing with the international recommended values, its values found to be within the international level. PMID- 29195165 TI - Psychometric evaluation of the Temporal Experience of Pleasure Scale (TEPS) in a German sample. AB - Anhedonia, or the inability to experience pleasure, is commonly observed in schizophrenia. It has been suggested that patients with schizophrenia are unable to predict future pleasurable events, but show intact experience of in-the-moment pleasure. Therefore, the Temporal Experience of Pleasure Scale (TEPS), a self report measure allowing the assessment of anticipatory and consummatory pleasure, has been developed. To validate the German version of the TEPS, we recruited 59 healthy control participants and 51 patients with schizophrenia or schizoaffective disorder who completed the TEPS as well as a battery of psychometric tests to assess psychopathology, in particular self-rated anhedonia and clinician-rated apathy as well as overall measures of negative symptoms. We found acceptable to good internal consistency and a factor structure comparable to the original version. Scores of the TEPS were related to measures of anhedonia and apathy, but not with other measures of psychopathology. The present results suggest that the German version of the TEPS shows adequate reliability and validity to assess the construct of anhedonia. However, differential aspects of anticipatory and consummatory pleasure should be further investigated in clinical samples. PMID- 29195164 TI - Elderly migrants in outpatient and inpatient care services in Baden Wurttemberg/Germany. AB - OBJECTIVE: Given the expected underrepresentation of elderly migrant populations in healthcare utilization we examined their proportion in nursing homes and care services for the elderly. We expected that cultural aspects were rarely addressed in the services' concepts. METHODS: A questionnaire was administered to all care providers; 66.3% of 2724 in- and outpatient services in Baden-Wurttemberg, Germany participated. RESULTS: 78% of the services provided healthcare to migrants, who accounted for 14.1% of the clientele. This proportion was higher in urban (e.g. Heilbronn: 16.1%) than in rural areas (e.g. Lake Constance: 7.7%) and was significantly (r = 0.545, p < .05) correlated with the proportion of migrants in the general population. 39.1% of the migrants came from Russia, Poland and Turkey. Migrants from Turkey preferred outpatients' rather than inpatients' services. While 87.4% of services employed migrants, only 20% of services provided measures to increase intercultural competency to their employees. CONCLUSIONS: Migrants utilize inpatient and outpatient services regularly as their proportion was closely associated to that of the general population. Although their number will likely increase in the near future, the vast majority of nursing facilities did not provide specialized measures to better meet the demands of residents with a migration background. PMID- 29195166 TI - Cognitive abilities and theory of mind in explaining communicative-pragmatic disorders in patients with schizophrenia. AB - Patients with schizophrenia usually show an impairment in their communicative pragmatic performance; they also have difficulties in cognitive functioning and Theory of Mind (ToM). In the literature it has been proposed that ToM and cognitive deficits have a role in explaining the communicative-pragmatic difficulties of patients with schizophrenia. However, the exact interplay of these functions is still not completely clear. The present research investigates the relationship between communicative-pragmatic, ToM and cognitive impairments (i.e. general intelligence, selective attention, speed processing and EF -working memory, inhibition and flexibility-) in a sample of 26 individuals with schizophrenia and matched controls. The linguistic and extralinguistic scales of the Assessment Battery of Communication (ABaCo), and a series of ToM and cognitive tasks were administered to patients and healthy controls. The results showed that individuals with schizophrenia performed less well than controls in all the tasks investigated. However, a hierarchical regression analysis showed that only ToM, and not cognitive functions, seems to be a predictive variable of patients' performance. Finally, a Fisher's exact test showed that there was not a stable significant relationship between ToM or EF and pragmatic impairment. PMID- 29195167 TI - Effects of short- and long-term aripiprazole treatment on Group I mGluRs in the nucleus accumbens: Comparison with haloperidol. AB - The D2 receptor partial agonist, aripiprazole, has shown increased therapeutic efficacy for schizophrenia, autism and Tourette's syndrome compared to traditional antipsychotics such as the D2 receptor antagonist, haloperidol. Recent evidence suggests this superior profile may be associated with downstream effects on glutamatergic synapses. Group 1 metabotropic glutamate receptors (mGluRs) and their endogenous modulators, Norbin and Homer1, are regulated by D2 receptor activity, particularly within the nucleus accumbens (NAc), a target region of aripiprazole and haloperidol. This study sought to evaluate the effects of aripiprazole on Group 1 mGluRs, Norbin and Homer1 in the NAc, in comparison to haloperidol. Sprague-Dawley rats were orally administered daily doses of aripiprazole (2.25mg/kg), haloperidol (0.3mg/kg) or vehicle for 1 or 10-weeks. Immunoblot analyses revealed Group 1 mGluR protein levels were not altered following 1-week and 10-week aripiprazole or haloperidol treatment, compared to vehicle treated rodents. However, 1-week aripiprazole and haloperidol treatment significantly elevated Homer1a and Norbin protein expression, respectively. After 10 weeks of treatment, aripiprazole, but not haloperidol, significantly increased Norbin expression. These findings indicate the antipsychotics, aripiprazole and haloperidol, exert differential temporal effects on Norbin and Homer1 expression that may have consequences on synaptic glutamatergic transmission underlying their therapeutic profile. PMID- 29195168 TI - Stochastic optimal generation bid to electricity markets with emissions risk constraints. AB - There are many factors that influence the day-ahead market bidding strategies of a generation company (GenCo) within the framework of the current energy market. Environmental policy issues are giving rise to emission limitation that are becoming more and more important for fossil-fueled power plants, and these must be considered in their management. This work investigates the influence of the emissions reduction plan and the incorporation of the medium-term derivative commitments in the optimal generation bidding strategy for the day-ahead electricity market. Two different technologies have been considered: the high emission technology of thermal coal units and the low-emission technology of combined cycle gas turbine units. The Iberian Electricity Market (MIBEL) and the Spanish National Emissions Reduction Plan (NERP) defines the environmental framework for dealing with the day-ahead market bidding strategies. To address emission limitations, we have extended some of the standard risk management methodologies developed for financial markets, such as Value-at-Risk (VaR) and Conditional Value-at-Risk (CVaR), thus leading to the new concept of Conditional Emission at Risk (CEaR). This study offers electricity generation utilities a mathematical model for determining the unit's optimal generation bid to the wholesale electricity market such that it maximizes the long-term profits of the utility while allowing it to abide by the Iberian Electricity Market rules as well as the environmental restrictions set by the Spanish National Emissions Reduction Plan. We analyze the economic implications for a GenCo that includes the environmental restrictions of this National Plan as well as the NERP's effects on the expected profits and the optimal generation bid. PMID- 29195169 TI - Modelling interactive effects of multiple disturbances on a coastal lake ecosystem: Implications for management. AB - Coastal lakes, also known as temporarily open/closed estuaries or intermittently closed and open lakes and lagoons, are common worldwide, are typically sites of high biodiversity and often contain abundant macrophyte populations. Anthropogenic stressors such as increased nutrient and sediment loading have adverse effects on submerged macrophytes, and when closed, the lack of tidal flushing makes coastal lakes highly susceptible to eutrophication. Lake openings to the sea may occur naturally, but many coastal lakes are also opened artificially, often to reduce inundation of surrounding land. Here we used a coupled hydrodynamic-ecological model (DYRESM-CAEDYM), modified to include dynamic feedback between submerged macrophyte biomass and sediment resuspension, to explore the interactive effects of multiple disturbances (openings, eutrophication and climate change) on the dynamics of primary producers in a coastal lake (Waituna Lagoon) in South Island, New Zealand. Our results indicate that with exposure to high external nutrient loads, the frequent disturbances caused by artificial openings prevent sustained dominance by algae (algal biomass averaged 192 g C m-2 with artificial openings compared to 453 g C m-2 with no openings). However, under current nutrient loading, climate change is likely to enhance the effects of eutrophication on the system (algal biomass averaged 227 g C m-2 with climate change compared with 192 g C m-2 for current climate). The model provides a decision-support tool to guide lake management in setting limits for nutrient loads and managing the opening regime, in order to prevent eutrophication and the potential collapse of the macrophyte community. PMID- 29195170 TI - Risk of maltreatment for siblings: Factors associated with similar and different childhood experiences in a dyadic sample of adult siblings. AB - Siblings share the same environment and thus potentially a substantial number of risk factors for child maltreatment. Furthermore, the number of siblings and the sibling constellation itself might pose a risk for child maltreatment. Little is known about the likelihood that more than one child in a family is maltreated and which factors increase the risk. This study sought to investigate similarities and differences in maltreatment in siblings and risk factors associated with the maltreatment of more than one child from the same family. Data on maltreatment during childhood and adolescence, family background, and sibling constellation were collected from 870 pairs of siblings. In the dyadic analyses, siblings reported similar maltreatment experiences, especially when any type of maltreatment was considered. Parents' mental health problems were significant predictors for maltreatment of at least one sibling. Father's mental health problems were predictive of maltreatment of both or only the younger sibling, mother's mental health problems of both or only the older sibling. Closeness in age and same gender of siblings did not emerge as a consistent predictor. The increasing number of siblings was a risk factor for any type of maltreatment of both siblings. The results highlight the need for preventive measures for families with a large number of children and with parents with mental health problems as well as a repeated risk assessment of all siblings in a family when one sibling was maltreated. PMID- 29195172 TI - Exposure to school violence at school and mental health of victimized adolescents: The mediation role of social support. AB - The purpose of the current study is to examine the mediation role of social support in the relationship between exposure to violence at school and mental health among adolescents within the framework of two structured models via structural equation model (SEM). The participants consist of a total of 1420 9th, 10th, and 11th grades high school students (54.5% girls and 45.5% boys). The students' ages ranged from 14 to 18 years with a mean of 16.11 (SD=0.91) for total sample. 38 percent of the participants are in the 9th grade, 34.1 percent are in the 10th grade, and 28 percent are in the 11th grade. Findings from both models indicated that social support mediated the relationships between exposure to violence and mental health among adolescents. Additionally, both models showed that the associations between exposure to violence, social support and mental health varied by gender. Contributions and implications of the current findings are discussed in detail. PMID- 29195171 TI - Commercially sexually exploited youths' health care experiences, barriers, and recommendations: A qualitative analysis. AB - The current study sought to understand commercially sexually exploited (CSE) youths' health care experiences, barriers to care, and recommendations for improving health care services. We conducted focus groups (N=5) with 18 CSE youth from February 2015 through May 2016 at two group homes serving CSE youth in Southern California. We performed thematic content analysis to identify emergent themes about CSE youths' perspectives on health care. Youth described facilitators to care, including availability of services such as screening for sexually transmitted infections, knowledge about sexual health, and a strong motivation to stay healthy. Barriers included feeling judged, concerns about confidentiality, fear, perceived low quality of services, and self-reliance. Overall, youth emphasized self-reliance and "street smarts" for survival and de emphasized "victimhood," which shaped their interactions with health care, and recommended that health providers develop increased understanding of CSE youth. Our findings suggest that providers and community agencies can play an essential role in raising awareness of the needs of CSE youth and meet their health needs through creating a non-judgmental environment in health care settings that validates the experiences of these youth. PMID- 29195173 TI - Developmental trajectories and longitudinal mediation effects of self-esteem, peer attachment, child maltreatment and depression on early adolescents. AB - OBJECTIVES: The purpose of this study is to identify the developmental trajectories of peer attachment, self-esteem, depression, and child maltreatment, and to understand the longitudinal mediation effects that peer attachment and self-esteem have on the influence of perceived abuse on early adolescent depression. METHODS: This study uses Year 1 to Year 5 data of the 4th grader panel of the Korea Youth Panel Survey (KYPS) and utilizes a multivariate latent growth model to analyze the main variables in the applicable data between 5th (i.e., Year 2) and 8th (i.e., Year 5) grades. RESULTS: The results indicate that from the 5th to the 8th grade, the degree of abuse and depression increases while self-esteem gradually decreases with slowly lowering peer attachment. A significant distribution of the initial values and the rate of change were present for all main variables of the study, confirming individual differences in time wise changes. Further, more exposure to abuse correlated with a decrease in self-esteem, while an increase in self-esteem greatly reduced depression. The initial value of self-esteem showed a partial mediation effect, whereas the rate of change indicated a full mediation effect with a significant longitudinal mediation effect. More experience of abuse during early adolescence indicated a lower degree of peer attachment, and a higher peer attachment was related to decreased depression. A significant partial mediation effect was present for both the initial value and the rate of change of peer attachment, and a longitudinal mediation effect was present. PRACTICE IMPLICATIONS: This study confirmed that self-esteem in early adolescents is an important protective factor that can greatly reduce the degree of depression, and suggests continuous interventions conducted to increase self-esteem in adolescence. Furthermore, by determining that peer attachment decreases the degree of depression in children at risk, the study emphasizes the healing aspect of adolescent peer attachment. PMID- 29195174 TI - Abusive fracture incidence over three decades at a level 1 pediatric trauma center. AB - Few studies have examined the incidence of abusive fractures in children. Only one study to date, from a single pediatric trauma center,has reported on the incidence of abusive fractures over time. That study showed a decrease in abusive fractures over a 24-year period. Our objective for this current study was to compare these published data with recent data from this same trauma center, allowing for a detailed comparison of the incidence of abusive fractures over a 30-year period. We included children <36months of age who presented to the emergency department of a level 1 pediatric trauma center (2007-2010) with>=1 fracture. Six experts from 3 different fields rated each case on the likelihood the fracture(s) was caused by abuse using an established 7- point scale, and a consensus rating was agreed upon for each case. The incidence of abusive fractures was calculated per 10,000 children <36months of age living in the geographic region and per 10,000 ED visits and was compared to previously published data for three prior time periods (1979-1983, 1991-1994, and 1999-2002) at the same pediatric trauma center. From 2007-2010, 551 children were identified, including 31 children who were rated as abused. The incidence of a child presenting with an abusive fracture in the county per year was 2.7/10,000 children <36months of age. The previous three time periods showed a countywide incidence of 3.2/10,000 (1979-1983), 1.7/10,000 (1991-1994), and 2.0/10,000 (1999 2002) (p for trend 0.34). The incidence per ED visit was 2.5/10,000 in the recent time period compared to 6.0/10,000 (1979-1983), 3.4/10,000 (1991-1994), and 2.5/10,000 (1999-2002) (p for trend <0.001). In this single institution review of fractures in children <36months of age, the incidence of abusive fractures has remained relatively constant over a 30-year period. PMID- 29195175 TI - Distribution of ARGs and MGEs among glacial soil, permafrost, and sediment using metagenomic analysis. AB - Antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) can be identified with metagenomic analyses comparing relatively pristine and human impacted environments. We collected samples from 3 different environments: glacial soil little affected by anthropogenic activity, deep permafrost dated to 5821 BP (before human antibiotics), and sediment from the Pearl River. Sulfonamides, tetracyclines, and fluoroquinolones were common in the sediment samples. Sulfonamides and tetracycline were not found in permafrost; tetracycline was also not found in glacial soil. ARGs from the sediment were more abundant and diverse than those from glacial soil and permafrost. More types of resistance mechanisms were also present in the sediment. The diversity of MGEs was significantly correlated with the abundance and diversity of ARGs. The result will help future workers to better understand the distribution of ARGs among environments more or less impacted by anthropogenic activities. PMID- 29195176 TI - Using the Asian clam as an indicator of microplastic pollution in freshwater ecosystems. AB - Bioindicators play an important role in understanding pollution levels, bioavailability and the ecological risks of contaminants. Several bioindicators have been suggested for understanding microplastic in the marine environment. A bioindicator for microplastics in the freshwater environment does not exist. In our previous studies, we found a high frequency of microplastic pollution in the Asian clam (Corbicula fluminea) in Taihu Lake, China. In the present study, we conducted a large-scale survey of microplastic pollution in Asian clams, water and sediment from 21 sites in the Middle-Lower Yangtze River Basin from August to October of 2016. The Asian clam was available in all sites, which included diverse freshwater systems such as lakes, rivers and estuaries. Microplastics were found at concentrations ranging from 0.3-4.9 items/g (or 0.4-5.0 items/individual) in clams, 0.5-3.1 items/L in water and 15-160 items/kg in sediment. Microfibers were the most dominant types of microplastics found, accounting for 60-100% in clams across all sampling sites. The size of microplastics ranged from 0.021-4.83 mm, and microplastics in the range of 0.25-1 mm were dominant. The abundance, size distribution and color patterns of microplastics in clams more closely resembled those in sediment than in water. Because microplastic pollution in the Asian clam reflected the variability of microplastic pollution in the freshwater environments, we demonstrated the Asian clam as an bioindicator of microplastic pollution in freshwater systems, particularly for sediments. PMID- 29195177 TI - Mean and turbulent mass flux measurements in an idealised street network. AB - Pollutant mass fluxes are rarely measured in the laboratory, especially their turbulent component. They play a major role in the dispersion of gases in urban areas and modern mathematical models often attempt some sort of parametrisation. An experimental technique to measure mean and turbulent fluxes in an idealised urban array was developed and applied to improve our understanding of how the fluxes are distributed in a dense street canyon network. As expected, horizontal advective scalar fluxes were found to be dominant compared with the turbulent components. This is an important result because it reduces the complexity in developing parametrisations for street network models. On the other hand, vertical mean and turbulent fluxes appear to be approximately of the same order of magnitude. Building height variability does not appear to affect the exchange process significantly, while the presence of isolated taller buildings upwind of the area of interest does. One of the most interesting results, again, is the fact that even very simple and regular geometries lead to complex advective patterns at intersections: parametrisations derived from measurements in simpler geometries are unlikely to capture the full complexity of a real urban area.

AB - A facile chemoselective one-pot strategy for the deprotection of oxime has been developed using Fe0-polyaniline composite nanofiber (Fe0-PANI), as a catalyst. Nano material based Fe0-PANI catalyst has been synthesized via in-situ polymerization of ANI monomer and followed by reductive deposition of Fe0 onto PANI matrix. The catalyst was characterized by FE-SEM, HR-TEM, BET, XRD, ATR FTIR, XPS and VSM techniques. The scope of the transformation was studied for aryl, alkyl and heteroarylketoxime with excellent chemoselectivity (>99%). Mechanistic investigations suggested the involvement of a cationic intermediate with Fe3+ active catalytic species. Substituent effect showed a linear free energy relationship. The activation energy (Ea) was calculated to be 17.46 kJ mol 1 for acetophenone oxime to acetophenone conversion. The recyclability of the catalyst demonstrated up to 10 cycles without any significant loss of efficiency. Based on the preliminary experiments a plausible mechanism has been proposed involving a carbocationic intermediate. PMID- 29195180 TI - Mechanistic insights into the role of glycosaminoglycans in delivery of polymeric nucleic acid nanoparticles by molecular dynamics simulations. AB - Delivery of polynucleotide-based therapeutics into target cells involves interactions with glycosaminoglycan chains that are located on cell membrane milieu. Mechanisms governing glycosaminoglycan-mediated changes in the nanoparticulate structures of polymer-polynucleotide complexes are unknown, and cannot be fully elucidated without atomistic level details of molecular interactions. We selected a representative nanoparticulate system consisting of a short interfering RNA (siRNA)-polyethylenimine complex, and performed all-atom molecular dynamics simulations with the prototypical glycosaminoglycan heparin. We monitored the binding between the complex constituents and the heparin, and identified key features contributing to the response of the siRNA nanoparticles to heparin. We observed three main metastable states that the siRNA nanoparticles might visit in the presence of heparin, which can be translated into different functional outcomes. By correlating our data with the widely different and seemingly contradictory roles previously assigned to glycosaminoglycans, this study provides unique insights into the discrepancies in the experimental literature concerning the role of glycosaminoglycans in the polymeric nanoparticle delivery.

AB - Nanoscale coordination polymers (NCPs) are promising nanomedicine platforms featured with biodegradability and versatile functionalities. However, multi-step post-synthesis surface modification is usually required to functionalize as-made NCPs before their biomedical applications. Moreover, efforts are still required to design therapeutic NCPs responsive to the unique tumor microenvironment to achieve more specific and effective therapy. Herein, we uncover a simple yet general strategy to synthesize a series of polyethylene glycol (PEG) modified NCPs via a one-step method by adding poly-histidine-PEG co-polymer into the mixture of metal ions and organic ligands during NCPs formation. With NCPs consisting Ca2+/dicarboxylic cisplatin (IV) prodrug as the example, we show that such Ca/Pt(IV)@pHis-PEG NCPs are highly sensitive to pH changes. With slightly negative charges and compact structure under pH 7.4 during blood circulation, those NCPs exhibit efficient passive accumulation in the tumor, in which the reduced pH (c.a. 6.5) would trigger charge conversion and size expansion to enhance their tumor retention and cell internationalization. After cellular uptake, NCPs within cell endo-/lysosomes with further reduced pH would then lead to decomposition of those NCPs and thus drug release. Chemotherapy with Ca/Pt(IV)@pHis-PEG NCPs in our animal tumor model demonstrates great efficacy under low drug doses, and is found to be particularly effective towards solid tumors with reduced pH.

AB - The outburst of superoxide anion (O2-) in mitochondrial during ischemia/reperfusion (I/R) process will cause a series of oxidative damage including polarity loss of mitochondrial membrane potential, overload of secondary cellular calcium, and cascade apoptosis. To monitor the O2- level fluctuations as well as to evaluate the relationship between O2- concentration and the degree of cell apoptosis during I/R process, we propose a ratiometric near-infrared mitochondrial targeting fluorescent probe Mito-Cy-Tfs for the detection of level changes of O2- in cells and in vivo. The probe Mito-Cy-Tfs is composed of three moieties: near-infrared heptamethine cyanine as fluorescence signal transducer, trifluoromethanesulfonamide as fluorescence modulator, and lipophilic triphenylphosphonium cation as mitochondrial guider. The probe can well locate in mitochondria and respond the concentration changes of endogenous O2- selectively and sensitively. The probe has been successfully utilized to image the endogenous O2- fluctuations in four kinds of cell I/R models (glucose deprivation/reperfusion, serum deprivation/reperfusion, oxygen deprivation/reperfusion and glucose-serum-oxygen deprivation/reperfusion). The probe also exhibits deep tissue penetration for real-time imaging of O2 concentration in liver of I/R mice model. We confirm that the adoption of ischemic preconditioning (IPC) and postconditioning (IPTC) can protect liver from I/R injury. The probe can be employed to accurately indicate and evaluate the mutual relationship between the levels of O2- and the degrees of organ damage during I/R, IPC and IPTC processes. The above applications make our new probe a potential candidate for the clinical surgery assessment. PMID- 29195183 TI - Impacts of exposure to black carbon, elemental carbon, and ultrafine particles from indoor and outdoor sources on blood pressure in adults: A review of epidemiological evidence. AB - INTRODUCTION: Ambient particulate air pollution is known to have detrimental effects on cardiovascular health but less is known about the specific effects of black carbon or elemental carbon (BC/EC) and ultrafine particles (UFP). METHODS: We present a narrative review of the epidemiological evidence related to the impact of exposure to BC/EC and UFP on blood pressure in adults. We searched PubMed and EMBASE in September 2017, using a predefined search strategy. Abstracts were screened using predefined inclusion criteria. Data collection was completed using a standard data extraction form. We focused on main effect estimates for associations between short (<=7 days) and long-term exposures to BC/EC and UFP and systolic (SBP) and diastolic blood pressure (DBP). Effect estimates were rescaled to enable direct comparisons between studies. RESULTS: Thirty publications were included in the review: 19 studies examined outdoor exposure to BC/EC, 11 examined outdoor UFP, three studies examined indoor BC and one study examined indoor UFP. In general, existing evidence supports a positive association between BC/EC and blood pressure. Evidence for outdoor UFP exposures were less clear as effect estimates were small in magnitude and confidence intervals often included the null. CONCLUSIONS: Existing evidence supports a positive association between BC/EC and blood pressure in adults, whereas UFPs do not appear to have a meaningful impact on blood pressure.

AB - Marine pollution has been increasing as a consequence of anthropogenic activities. The preservation of marine ecosystems, as well as the safety of harvested seafood, are nowadays a global concern. Here, we report for the first time the contamination levels of a large set of 99 emerging and persistent organic contaminants (butyltins (BTs), polycyclic aromatic hydrocarbons (PAHs), pesticides including pyrethroids, pharmaceuticals and personal care products (PCPs) and flame retardants) in roe/gonads of sea urchin Paracentrotus lividus. Sea urchins are a highly prized worldwide delicacy, and the harvesting of this seafood has increased over the last decades, particularly in South West Atlantic coast, where this organism is harvested mainly for exportation. Sampling was performed in three harvesting sites of the NW Portuguese coast subjected to distinct anthropogenic pressures: Carreco, Praia Norte and Vila Cha, with sea urchins being collected in the north and south areas of each site. Butyltins and pharmaceuticals were not found at measurable levels. Several PAHs, four pyrethroids insecticides, four PCPs and eleven flame retardants were found in roe/gonads of sea urchins, though in general at low levels. Differences among harvesting sites and between areas within each site were found, the lowest levels of contaminants being registered in Carreco. The accumulation of contaminants in sea urchins' roe/gonads seemed to reflect the low anthropogenic pressure felt in the sampling sites. Nevertheless, taking into account the low accumulated levels of chemicals, results indicate that sea urchins collected in South West Atlantic coast are safe for human consumption. PMID- 29195185 TI - Fine particulate matters: The impact of air quality standards on cardiovascular mortality. AB - BACKGROUND: In 1997 the U.S. Environmental Protection Agency set the first annual National Ambient Air Quality Standard (NAAQS) for fine particulate matter (PM2.5). Although the weight of scientific evidence has determined that a causal relationship exists between PM2.5 exposures and cardiovascular effects, few studies have concluded whether NAAQS-related reductions in PM2.5 led to improvements in public health. METHODS: We examined the change in cardiovascular (CV) mortality rate and the association between change in PM2.5 and change in CV mortality rate before (2000-2004) and after implementation of the 1997 annual PM2.5 NAAQS (2005-2010) among U.S. counties. We further examined how the association varied with respect to two factors related to NAAQS compliance: attainment status and design values (DV). We used difference-in-differences and linear regression models, adjusted for sociodemographic confounders. FINDINGS: Across 619 counties, there were 1.10 (95% CI: 0.37, 1.82) fewer CV-deaths per year per 100,000 people for each 1ug/m3 decrease in PM2.5. Nonattainment counties had a twofold larger reduction in mean annual PM2.5, 2.1ug/m3, compared to attainment counties, 0.97ug/m3. CV-mortality rate decreased by 0.59 (95% CI: 0.54, 1.71) in nonattainment and 1.96 (95% CI: 0.77, 3.15) deaths per 100,000 people for each 1ug/m3 decrease in PM2.5 in attainment counties. When stratifying counties by DV, results were similar: counties with DV greater than 15ug/m3 experienced the greatest decrease in mean annual PM2.5 (2.29ug/m3) but the smallest decrease in CV-mortality rate per unit decrease in PM2.5, 0.73 (95% CI: 0.57, 2.02). INTERPRETATION: We report a significant association between the change in PM2.5 and the change in CV-mortality rate before and after the implementation of NAAQS and note that the health benefits per 1ug/m3 decrease in PM2.5 persist at levels below the current national standard.

AB - Little is known about the forces that determine the assembly of diverse bacterial communities inhabiting drinking water treatment filters and how this affects drinking water quality. Two contrasting ecological theories can help to understand how natural microbial communities assemble; niche theory and neutral theory, where environmental deterministic factors or stochastic factors predominate respectively. This study investigates the development of the microbial community on two common contrasting filter materials (quartz sand and granular activated carbon-GAC), to elucidate the main factors governing their assembly, through the evaluation of environmental (i.e. filter medium type) and stochastic forces (random deaths, births and immigration). Laboratory-scale filter columns were used to mimic a rapid gravity filter; the microbiome of the filter materials, and of the filter influent and effluent, was characterised using next generation 16S rRNA gene amplicon sequencing and flow-cytometry. Chemical parameters (i.e. dissolved organic carbon, trihalomethanes formation) were also monitored to assess the final effluent quality. The filter communities seemed to be strongly assembled by selection rather than neutral processes, with only 28% of those OTUs shared with the source water detected on the filter medium following predictions using a neutral community model. GAC hosted a phylogenetically more diverse community than sand. The two filter media communities seeded the effluent water, triggering differences in both water quality and community composition of the effluents. Overall, GAC proved to be better than sand in controlling microbial growth, by promoting higher bacterial decay rates and hosting less bacterial cells, and showed better performance for putative pathogen control by leaking less Legionella cells into the effluent water.

PMID- 29195188 TI - Long-term effectiveness of cognitive behavioral therapy for youth with anxiety disorders. AB - Cognitive behavioral therapy (CBT) has demonstrated favorable long-term outcomes in youth with anxiety disorders in efficacy trials. However, long-term outcomes of CBT delivered in a community setting are uncertain. This study examined the long-term outcomes of individual (ICBT) and group CBT (GCBT) in youth with anxiety disorders treated in community mental health clinics. A total of 139 youth (mean age at assessment 15.5 years, range 11-21 years) with a principal diagnosis of separation anxiety disorder (SAD), social anxiety disorder (SOP), and/or generalized anxiety disorder (GAD) were evaluated, on average, 3.9 years post-treatment (range 2.2-5.9 years). Outcomes included loss of all inclusion anxiety diagnoses, loss of the principal anxiety diagnosis and changes in youth- and parent-rated youth anxiety symptoms. At long-term follow-up, there was loss of all inclusion anxiety diagnoses in 53%, loss of the principal anxiety diagnosis in 63% of participants as well as significant reductions in all anxiety symptom measures. No statistical significant differences in outcome were obtained between ICBT and GCBT. Participants with a principal diagnosis of SOP had lower odds for recovery, compared to those with a principal diagnosis of SAD or GAD. In conclusion, outcomes of CBT for youth anxiety disorders delivered in community mental health clinics were improved at nearly 4 years post-treatment, and recovery rates at long-term follow-up were similar to efficacy trials. PMID- 29195189 TI - "One of the greatest medical success stories:" Physicians and nurses' small stories about vaccine knowledge and anxieties. AB - In recent years, the Canadian province of Alberta experienced outbreaks of measles, mumps, pertussis, and influenza. Even so, the dominant cultural narrative maintains that vaccines are safe, effective, and necessary to maintain population health. Many vaccine supporters have expressed anxieties that stories contradicting this narrative have lowered herd immunity levels because they frighten the public into avoiding vaccination. As such, vaccine policies often emphasize educating parents and the public about the importance and safety of vaccination. These policies rely on health professionals to encourage vaccine uptake and assume that all professionals support vaccination. Health professionals, however, are socially positioned between vaccine experts (such as immunologists) and non-experts (the wider public). In this article, I discuss health professionals' anxieties about the potential risks associated with vaccination and with the limitations of Alberta's immunisation program. Specifically, I address the question: If medical knowledge overwhelmingly supports vaccination, then why do some professionals continue to question certain vaccines? To investigate this topic, I interviewed twenty-seven physicians and seven nurses. With stock images and small stories that interviewees shared about their vaccine anxieties, I challenge the common assumption that all health professionals support vaccines uncritically. All interviewees provided generic statements that supported vaccination and Alberta's immunisation program, but they expressed anxieties when I asked for details. I found that their anxieties reflected nuances that the culturally dominant vaccine narrative overlooks. Particularly, they critiqued the influence that pharmaceutical companies, the perceived newness of specific vaccines, and the limitations of medical knowledge and vaccine schedules. PMID- 29195190 TI - Courtesy stigma: A concealed consternation among caregivers of people affected by leprosy. AB - This study explored experiences of courtesy stigma among caregivers of people affected by leprosy. Using a qualitative research approach, twenty participants were purposively selected and in-depth interviews conducted. The interviews were audio-recorded, transcribed, and analyzed to identify emerging themes that addressed objectives of the study. The findings indicated that caregivers of people affected by leprosy experienced courtesy stigma. Evidence showed that fear of contagion underpinned caregivers' experiences, especially in employment and romantic relationships. In addition, participants adopted different strategies (disregarding, concealment, education, faith-based trust) to handle courtesy stigma. The findings demonstrate that psychosocial support and financial assistance to caregivers are necessary considerations for attainment of effective care for people affected by leprosy. PMID- 29195191 TI - Self-disturbances, cognitive biases and insecure attachment as mechanisms of the relationship between traumatic life events and psychotic-like experiences in non clinical adults - A path analysis. AB - Although traumatic life events have been linked to psychotic-like experiences, the mechanisms of the relationship remain unclear. We investigated whether insecure (anxious and avoidant) attachment styles, cognitive biases and self disturbances serve as significant mediators in the relationship between traumatic life events and psychotic-like experiences in non-clinical sample. Six-hundred and ninety healthy participants (522 females) who have not ever been diagnosed with psychiatric disorders took part in the study. Participants completed self report scales that measure traumatic life events, psychotic-like experiences, cognitive biases, attachment styles and self-disturbances. Our model was tested with path analysis. Our integrated model fit to the data with excellent goodness of-fit indices. The direct effect was significantly reduced after the mediators were included. Significant pathways from traumatic life events to psychotic-like experiences were found through self-disturbances and cognitive biases. Traumatic life events were associated with anxious attachment through cognitive biases. Self-disturbances, cognitive biases and anxious attachment had a direct effect on psychotic-like experiences. The results of our study tentatively suggest that traumatic life events are related with psychotic-like experiences through cognitive biases and self-disturbances. Further studies in clinical samples are required to verify our model. PMID- 29195192 TI - Spectroscopic profiling and computational study of the binding of tschimgine: A natural monoterpene derivative, with calf thymus DNA. AB - DNA is a major target for a number of anticancer substances. Interaction studies between small molecules and DNA are essential for rational drug designing to influence main biological processes and also introducing new probes for the assay of DNA. Tschimgine (TMG) is a monoterpene derivative with anticancer properties. In the present study we tried to elucidate the interaction of TMG with calf thymus DNA (CT-DNA) using different spectroscopic methods. UV-visible absorption spectrophotometry, fluorescence and circular dichroism (CD) spectroscopies as well as molecular docking study revealed formation of complex between TMG and CT DNA. Binding constant (Kb) between TMG and DNA was 2.27*104M-1, that is comparable to groove binding agents. The fluorescence spectroscopic data revealed that the quenching mechanism of fluorescence of TMG by CT-DNA is static quenching. Thermodynamic parameters (DeltaH<0 and DeltaS<0) at different temperatures indicated that van der Waals forces and hydrogen bonds were involved in the binding process of TMG with CT-DNA. Competitive binding assay with methylene blue (MB) and Hoechst 33258 using fluorescence spectroscopy displayed that TMG possibly binds to the minor groove of CT-DNA. These observations were further confirmed by CD spectral analysis, viscosity measurements and molecular docking. PMID- 29195193 TI - Vibrational spectroscopic characterization of cyclic and acyclic molecular rotors with 1,4-diethynylphenylene-d4 rotators. AB - The synthesis and characterization of acyclic and cyclic molecular rotors with 1,4-diethynylphenylene-d4 rotators are described. The ATR-FTIR and Raman spectra of acyclic rotor 3 and cyclic rotor 5E were measured and interpreted. A feature of ATR-FTIR spectrum of rotor 5E is a strong two-component band around 1730cm-1 attributed to symmetric and asymmetric stretching vibration of the carbonyl group, while this is not observed in rotor 3. Raman investigation in the wide temperature range of 350 - 10K was carried out. The splitting of Raman bands in the region of stretching vibration of CC double and triple bonds at 170 and 260K for rotor 5E is observed. The splitting of bands is due to changes in molecular structure. PMID- 29195194 TI - Oxygenic denitrification for nitrogen removal with less greenhouse gas emissions: Microbiology and potential applications. AB - Nitrogen pollution is a worldwide problem and has been extensively treated by canonical denitrification (CDN) process. However, the CDN process generates several issues such as intensive greenhouse gas (GHG) emissions. In the past years, a novel biological nitrogen removal (BNR) process of oxygenic denitrification (O2DN) has been proposed as a promising alternative to the CDN process. The classic denitrification four steps are simplified to three steps by O2DN bacteria without producing and releasing the intermediate nitrous oxide (N2O), a potent GHG. In this article, we summarized the findings in previous literatures as well as our results, including involved microorganisms and metabolic mechanisms, functional genes and microbial detection, kinetics and influencing factors and their potential applications in wastewater treatment. Based on our knowledge and experience, the benefits and limitations of the current O2DN process were analyzed. Since O2DN is a new field in wastewater treatment, more research and application is required, especially the development of integrated processes and the quantitative assessment of the contribution of O2DN process in natural habitats and engineered systems. PMID- 29195195 TI - Economic impacts of urban flooding in South Florida: Potential consequences of managing groundwater to prevent salt water intrusion. AB - High-value urban zones in coastal South Florida are considered particularly vulnerable to salt water intrusion into the groundwater-based, public water supplies caused by sea level rise (SLR) in combination with the low topography, existing high water table, and permeable karst substrate. Managers in the region closely regulate water depths in the extensive South Florida canal network to control closely coupled groundwater levels and thereby reduce the risk of saltwater intrusion into the karst aquifer. Potential SLR adaptation strategies developed by local managers suggest canal and groundwater levels may have to be increased over time to prevent the increased salt water intrusion risk to groundwater resources. However, higher canal and groundwater levels cause the loss of unsaturated zone storage and lead to an increased risk of inland flooding when the recharge from rainfall exceeds the capacity of the unsaturated zone to absorb it and the water table reaches the surface. Consequently, higher canal and groundwater levels are also associated with increased risk of economic losses, especially during the annual wet seasons. To help water managers and urban planners in this region better understand this trade-off, this study models the relationships between flood insurance claims and groundwater levels in Miami-Dade County. Via regression analyses, we relate the incurred number of monthly flood claims in 16 Miami-Dade County watersheds to monthly groundwater levels over the period from 1996 to 2010. We utilize these estimated statistical relationships to further illustrate various monthly flood loss scenarios that could plausibly result, thereby providing an economic quantification of a "too much water" trade off. Importantly, this understanding is the first of its kind in South Florida and is exceedingly useful for regional-scale hydro-economic optimization models analyzing trade-offs associated with high water levels. PMID- 29195196 TI - Adaptation of Gammarus pulex to agricultural insecticide contamination in streams. AB - Exposure to pesticides affects non-target aquatic communities, with substantial consequences on ecosystem services. Adaptation of exposed populations may reduce the effects of pesticides. However, it is not known under which conditions adaptation occurs when only a low toxic pressure from pesticides is present. Here, we show that Gammarus pulex, a dominant macroinvertebrate species in many agricultural streams, acquires increased tolerance to pesticides when recolonization from non-contaminated refuge areas is low. Populations in the field that were exposed to pesticides at concentrations several orders of magnitude below considerable acute effects showed almost 3-fold higher tolerance to the neonicotinoid insecticide clothianidin (mean EC50 218MUgL-1) compared with non-exposed populations (mean EC50 81MUgL-1). This tolerance of exposed populations increased from 2- to 4-fold with increasing distance to the next refuge area (0 to 10km). We conclude that the development of tolerance for non target species may occur at very low concentrations, much below those affecting sensitive test organisms and also lower than those predicted to be safe by governmental risk assessment frameworks. PMID- 29195197 TI - Microbial decomposition is highly sensitive to leaf litter emersion in a permanent temperate stream. AB - Drought frequency and intensity in some temperate regions are forecasted to increase under the ongoing global change, which might expose permanent streams to intermittence and have severe repercussions on stream communities and ecosystem processes. In this study, we investigated the effect of drought duration on microbial decomposition of Populus nigra leaf litter in a temperate permanent stream (Oliveira, NW Portugal). Specifically, we measured the response of the structural (assemblage composition, bacterial and fungal biomass) and functional (leaf litter decomposition, extracellular enzyme activities (EEA), and fungal sporulation) parameters of fungal and bacterial communities on leaf litter exposed to emersion during different time periods (7, 14 and 21d). Emersion time affected microbial assemblages and litter decomposition, but the response differed among variables. Leaf decomposition rates and the activity of beta glucosidase, cellobiohydrolase and phosphatase were gradually reduced with increasing emersion time, while beta-xylosidase reduction was similar when emersion last for 7 or more days, and the phenol oxidase reduction was similar at 14 and 21days of leaf emersion. Microbial biomass and fungal sporulation were reduced after 21days of emersion. The structure of microbial assemblages was affected by the duration of the emersion period. The shifts in fungal assemblages were correlated with a decreased microbial capacity to degrade lignin and hemicellulose in leaf litter exposed to emersion. Additionally, some resilience was observed in leaf litter mass loss, bacterial biomass, some enzyme activities and structure of fungal assemblages. Our study shows that drought can strongly alter structural and functional aspects of microbial decomposers. Therefore, the exposure of leaf litter to increasing emersion periods in temperate streams is expected to affect decomposer communities and overall decomposition of plant material by decelerating carbon cycling in streams. PMID- 29195198 TI - Single microbial fuel cell reactor for coking wastewater treatment: Simultaneous carbon and nitrogen removal with zero alkaline consumption. AB - The use of several individual reactors for sequential removal of organic compounds and nitrogen, in addition to the required alkaline addition in aerobic reactors, remain outstanding technical challenges to the traditional biological treatment of coking wastewater. Here, we report the utilization of a single microbial fuel cell (MFC) reactor that performs simultaneous carbon and nitrogen removal with zero alkaline consumption, as evidenced by the results of the batch fed and continuous-flow experiments. The MFC exhibited faster reaction kinetics for COD and total nitrogen (TN) removal than the same configured reactor analogous to the traditional aerobic biological reactor (ABR). At a hydraulic retention time (HRT) of 125 h, the efficiencies of COD and TN removal in the MFC reached 83.8+/-3.6% and 97.9+/-2.1%, respectively, much higher than the values of 73.8+/-2.9% and 50.2+/-5.0% obtained in the ABR. Furthermore, the degradation in the MFC of the main organic components, including phenolic compounds (such as phenol, 2-methylphenol, 3-methylphenol, 4-methylphenol, and 2,4-dimethlyphenol) and nitrogenous heterocyclic compounds (such as quinolone, pyridine, indole, and isoquinolone) was greater than that in the ABR. The enhancing effect was attributed to the ability of the MFC to self-adjust the pH. It was also manifested by the increased abundances of heterotrophs, nitrifiers, and denitrifiers in the MFC. The correlations between the current density and the rates of COD and TN removal suggest that the extent of the current from the anode to the cathode is a critical parameter for the overall performance of MFCs in the treatment of coking wastewater. PMID- 29195199 TI - Comparison of parameterizations for the atmospheric extinction coefficient in Lin'an, China. AB - A more precise atmospheric extinction coefficient would be advantageous for improving air quality (visibility) forecasting. In this study, the size distribution, chemical composition and relative humidity were measured in Lin'an from January 9 to 31, 2015. The merits and weaknesses of three parameterization schemes are discussed in this paper, including the non-linear fitting scheme, the IMPROVE (Interagency Monitoring of Protected Visual Environment) algorithm and the kappa-elemental carbon (EC)-Mie model. Comparing the three schemes mentioned above, we find that the non-linear fitting equation requires the least amount of data, and its calculation process is the simplest. However, its calculated values are significantly influenced by specific data and fitting formulas. The uncertainty of the variable coefficients makes it difficult to directly implement this method for other datasets. The calculated values of the three versions of the IMPROVE algorithm strongly correlate with the measured values, with slopes near 1.0 and statistical indexes (R2) of 0.848, 0.858 and 0.866. However, this method is affected by the chemical compositions of the particles in different regions; for example, when the quality of PM2.5 is reconstructed from the measured data, the coefficients of different components change, thus affecting the final results. The kappa-EC-Mie model objectively reflects the changes in the law of visibility, as the model considers both the chemical composition and size distribution of particles, and its predominant merit is derived from the fact that it is calculated without an empirical formula, which may eliminate the computational errors caused by the uncertainties of coefficients. PMID- 29195200 TI - Spatial distribution and seasonal variation of four current-use pesticides (CUPs) in air and surface water of the Bohai Sea, China. AB - Current-use pesticides (CUPs) are widely used in agriculture, and some are listed as persistent organic pollutants (POPs) due to their bioaccumulative and toxic properties. China is one of the largest producers and users of pesticides in the world. However, very limited data are available about the environmental fates of CUPs. Four CUPs (trifluralin, chlorothalonil, chlorpyrifos, and dicofol) in surface seawater and low atmospheric samples taken during research cruises on the Bohai Sea in August and December 2016 and February 2017 were analyzed, we added the spring data sampled in May 2012 to the discussion of seasonal variation. In our study, chlorpyrifos was the most abundant CUPs in the gas phase with a mean abundance of 59.06+/-126.94pgm-3, and dicofol had the highest concentration dissolved in seawater (mean: 115.94+/-123.16pgL-1). The concentrations of all target compounds were higher during May and August due to intensive use and relatively high temperatures in the spring and summer. Backward trajectories indicated that air masses passing through the eastern coast of the Bohai Sea contained high concentrations of pollutants, while the air masses from the Bohai and Yellow Seas were less polluted. The high concentration of pollutants in seawater was not only influenced by high yields from the source region of production or usage, but also by input from polluted rivers. Volatilization from surface water was found to be an important source of trifluralin and chlorpyrifos in the air. Air-sea gas exchange of chlorothalonil underwent strong net deposition (mean FRs: 51.67), which was driven by higher concentrations in air and indicates that the Bohai Sea acted as a sink for chlorothalonil. PMID- 29195201 TI - A fuzzy multicriteria categorization of the GALDIT method to assess seawater intrusion vulnerability of coastal aquifers. AB - Groundwater constitutes the primary source of fresh water for >1.2 billion people living in coastal zones. However, the threat of seawater intrusion is widespread in coastal aquifers mainly due to overexploitation of groundwater. In the present study, a modified fuzzy multicriteria categorization into non-ordered categories method was developed in order to modify the standard GALDIT method and assess seawater intrusion vulnerability in a coastal aquifer of northern Greece. The method is based on six parameters: groundwater occurrence, aquifer hydraulic conductivity, groundwater level, distance from the shore, impact of the existing status of seawater intrusion, and aquifer thickness. Initially, the original method was applied and revealed a zone of high vulnerability running parallel to the coastline and covering an area of 8.6km2. The modified GALDIT-F method achieved higher discretization of vulnerability zones which is essential to build a rational management plan to prevent seawater intrusion. The GALDIT-F approach also distinguished an area of the aquifer that is influenced by geothermal fluids. In total, twenty-five categories were produced corresponding to different vulnerability degrees according to the initial method (High, Moderate, Low) as well as the area influenced by geothermal fluids. Finally, a road map was developed in order to adapt management strategies to GALDIT-F categories and prevent and mitigate seawater intrusion. The proposed management strategies of the coastal aquifer include managed aquifer recharge (MAR) implementation, reallocation of existing wells, optimization of pumping rates during the hydrological year, and a detailed monitoring plan. PMID- 29195202 TI - Exportation of dissolved (inorganic and organic) and particulate carbon from mangroves and its implication to the carbon budget in the Indian Sundarbans. AB - Mangroves are known for exchanging organic and inorganic carbon with estuaries and oceans but studies that have estimated their contribution to the global budget are limited to a few mangrove ecosystems which exclude world's largest the Sundarbans. Here, we worked in the Indian Sundarbans and in the Hooghly river/estuary in May (pre-monsoon) and December (post-monsoon), 2014. Aims were, i) to quantify the riverine export of particulate organic carbon (POC) and dissolved organic and inorganic carbon (DOC, DIC)) of the Hooghly into the Bay of Bengal (BoB), ii) to estimate the C export (DOC, DIC, POC) from the Sundarbans into the BoB by using a simple mixing model, as well as iii) to revise the existing C budget constructed for the mangroves. The riverine exports of POC, DOC and DIC account for 0.07TgCyr-1, 0.34TgCyr-1 and 4.14TgCyr-1, respectively, and were largest during the monsoon period. Results revealed that mangrove plant derived organic matter and its subsequent degradation is the primary source of DIC and DOC in the Hooghly estuary whereas POC is linked to soil erosion. Mangroves are identified as a major source of carbon (POC, DOC, DIC) transported from the Sundarbans into the BoB, with export rates of 0.58 TgCyr-1, 3.03TgCyr-1, and 3.69TgCyr-1 respectively, altogether amounting to 7.3TgCyr-1. This C export from the Indian Sundarbans exceeds the 'missing C' of the previous budget, thus necessitating further research to finally resolve the mangrove C budget. However, these first baseline data on C exports from the world's largest deltaic mangrove improves limited global data inventory and signifies the need of acquiring more data from different mangrove settings to reduce uncertainties. PMID- 29195203 TI - Environmental forcing on the flux of organic-walled dinoflagellate cysts in recent sediments from a subtropical lagoon in the Gulf of California. AB - To evaluate the relationship of changes in organic-walled dinoflagellate cyst (dinocyst) fluxes to sediments with environmental variables (air and sea surface temperatures, El Nino conditions, rainfall, and terrigenous index), cyst assemblages were analyzed in a 210Pb-dated sediment core (~100years) from the pristine San Jose Lagoon (San Jose Island, SW Gulf of California). The dinocyst abundance ranged from 3784 to 25,108cystsg-1 and fluxes were of the order of 103 104cystscm-2yr-1. Lingulodinium machaerophorum, Polysphaeridium zoharyi and Spiniferites taxa accounted for 96% of the total dinocyst assemblages, and the abundances of these species increased towards the core surface. P. zoharyi fluxes increased from about 1965 onwards. Redundancy analyses, showed that mean minimum air temperature and terrigenous index were the key factors governing dinocyst fluxes. In this study, dinocyst fluxes of dominant taxa had responded to changes in climate-dependent environmental variables during the past ~20years; this may also be the case in other subtropical coastal lagoons.

AB - The chemical compositions in PM2.5 in metropolitan areas have obtained lots of attentions, of which concerns of airborne trace elements are relatively lacking. Here, PM2.5 samples were collected simultaneously in one year at four urban sites (Zibo (ZB), Zaozhuang (ZZ), Qingdao (QD) and Jinan (JN (Shandong University)), and a rural site (JN (Miaopu)) in Shandong province. 25 elements (Al, Na, Cl, Mg, Si, S, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Sr, Cd, Ba and Pb) in PM2.5 were measured by wavelength dispersive X-ray fluorescence spectrometer (WDXRF). Most trace elements (Al, Na, Cl, Mg, Si, Ca, Ti, Mn, Fe, Co, Ni, As, Se, Br, Cd, Ba and Pb) exhibited the highest levels at ZB and the lowest at QD. Meanwhile, they presented obvious seasonal variations with the highest concentrations in winter or spring and the lowest in summer. S and K were the most abundant elements in the area. In the non-crustal trace metal elements, Zn, Pb and Mn presented the highest concentrations. Positive matrix factorization (PMF) modeling revealed that secondary formation, coal combustion and industry emissions were the main sources in the region. The health risk assessments suggested that at the five sites Cd (diet) for adults, Pb and Co for children, and Mn (diet) for both adults and children (at ZB and SDU sites) had non carcinogenic risks. As and Pb for adults and children existed carcinogenic risks, especially Pb for children. The sources of these elements with health risks were further explored. Notably, Cd, As and Pb should be paid special attention in the area due to their high concentrations in aerosol water exceeding the acceptable health risks, especially Pb.

AB - Phthalic Acid Esters (PAEs) are a group of emerging organic contaminants that have become a serious issue because of their ubiquitous presence and hazardous impact on the marine environment worldwide. Seawater samples were collected monthly from December 2013 to November 2014 in the northwestern Mediterranean Sea (Marseille Bay). The samples were analyzed for dissolved organic carbon (DOC) as well as the molecular distribution of dissolved PAEs by using solid phase extraction followed by gas chromatography and mass spectrometry (GC/MS) analyses. The results demonstrated the occurrence of six PAEs, including dimethyl phthalate (DMP), diethyl phthalate (DEP), di-isobutyl phthalate (DiBP), di-n-butyl phthalate (DnBP), benzylbutyl phthalate (BzBP) and diethylhexyl phthalate (DEHP), with total concentrations ranging from 130 to 1330ngL-1 (av. 522ngL-1). In Marseille Bay, the highest concentrations were detected in the bottom water from June to November 2014 and in the whole water column during the winter mixing period. This result suggests that resuspension of PAE-rich sediment, in relation to the accumulation of plastic debris above the seabed, or the higher degradation rate in the upper layer of the water column, plays a significant role in the PAE dynamics in coastal water. DEHP was the most abundant PAE in all of the surface samples and the summer bottom samples, followed by DiBP and DnBP, which also represent the largest fractions in the other bottom samples. PMID- 29195206 TI - Effects of changing climate on European stream invertebrate communities: A long term data analysis. AB - Long-term observations on riverine benthic invertebrate communities enable assessments of the potential impacts of global change on stream ecosystems. Besides increasing average temperatures, many studies predict greater temperature extremes and intense precipitation events as a consequence of climate change. In this study we examined long-term observation data (10-32years) of 26 streams and rivers from four ecoregions in the European Long-Term Ecological Research (LTER) network, to investigate invertebrate community responses to changing climatic conditions. We used functional trait and multi-taxonomic analyses and combined examinations of general long-term changes in communities with detailed analyses of the impact of different climatic drivers (i.e., various temperature and precipitation variables) by focusing on the response of communities to climatic conditions of the previous year. Taxa and ecoregions differed substantially in their response to climate change conditions. We did not observe any trend of changes in total taxonomic richness or overall abundance over time or with increasing temperatures, which reflects a compensatory turnover in the composition of communities; sensitive Plecoptera decreased in response to warmer years and Ephemeroptera increased in northern regions. Invasive species increased with an increasing number of extreme days which also caused an apparent upstream community movement. The observed changes in functional feeding group diversity indicate that climate change may be associated with changes in trophic interactions within aquatic food webs. These findings highlight the vulnerability of riverine ecosystems to climate change and emphasize the need to further explore the interactive effects of climate change variables with other local stressors to develop appropriate conservation measures. PMID- 29195207 TI - Spatial diversification of agroecosystems to enhance biological control and other regulating services: An agroecological perspective. AB - Spatial diversification of crop and non-crop habitats in farming systems is promising for enhancing natural regulation of insect pests. Nevertheless, results from recent syntheses show variable effects. One explanation is that the abundance and diversity of pests and natural enemies are affected by the composition, design and management of crop and non-crop habitats. Moreover, interactions between both local and landscape elements and practices carried out at different spatial scales may affect the regulation of insect pests. Hence, research is being conducted to understand these interdependencies. However, insects are not the only pests and pests are not the only elements to regulate in agroecosystems. Broadening the scope could allow addressing multiple issues simultaneously, but also solving them together by enhancing synergies. Indeed, spatial diversification of crop and non-crop habitats can allow addressing the issues of weeds and pathogens, along with being beneficial to several other regulating services like pollination, soil conservation and nutrient cycling. Although calls rise to develop multifunctional landscapes that optimize the delivery of multiple ecosystem services, it still represents a scientific challenge today. Enhancing interdisciplinarity in research institutions and building interrelations between scientists and stakeholders may help reach this goal. Despite obstacles, positive results from research based on such innovative approaches are encouraging for engaging science in this path. Hence, the aim of the present paper is to offer an update on these issues by exploring the most recent findings and discussing these results to highlight needs for future research. PMID- 29195208 TI - Validation of Arxula Yeast Estrogen Screen assay for detection of estrogenic activity in water samples: Results of an international interlaboratory study. AB - Endocrine-active substances can adversely impact the aquatic ecosystems. A special emphasis is laid, among others, on the effects of estrogens and estrogen mimicking compounds. Effect-based screening methods like in vitro bioassays are suitable tools to detect and quantify endocrine activities of known and unknown mixtures. This study describes the validation of the Arxula-Yeast Estrogen Screen (A-YES(r)) assay, an effect-based method for the detection of the estrogenic potential of water and waste water. This reporter gene assay, provided in ready to use format, is based on the activation of the human estrogen receptor alpha. The user-friendly A-YES(r) enables inexperienced operators to rapidly become competent with the assay. Fourteen laboratories from four countries with different training levels analyzed 17beta-estradiol equivalent concentrations (EEQ) in spiked and unspiked waste water effluent and surface water samples, in waste water influent and spiked salt water samples and in a mixture of three bisphenols. The limit of detection (LOD) for untreated samples was 1.8ng/L 17beta estradiol (E2). Relative repeatability and reproducibility standard deviation for samples with EEQ above the LOD (mean EEQ values between 6.3 and 20.4ng/L) ranged from 7.5 to 21.4% and 16.6 to 28.0%, respectively. Precision results are comparable to other frequently used analytical methods for estrogens. The A YES(r) has been demonstrated to be an accurate, precise and robust bioassay. The results have been included in the ISO draft standard. The assay was shown to be applicable for testing of typical waste water influent, effluent and saline water. Other studies have shown that the assay can be used with enriched samples, which lower the LOD to the pg/L range. The validation of the A-YES(r) and the development of a corresponding international standard constitute a step further towards harmonized and reliable bioassays for the effect-based analysis of estrogens and estrogen-like compounds in water samples. PMID- 29195209 TI - Daphnia magna filtration efficiency and mobility in laminar to turbulent flows. AB - Daphnia are filter feeder organisms that prey on small particles suspended in the water column. Since Daphnia individuals can feed on wastewater particles, they have been recently proposed as potential organisms for tertiary wastewater treatment. However, analysing the effects of hydrodynamics on Daphnia individuals has scarcely been studied. This study focuses then, on quantifying the filtration and swimming velocities of D. magna individuals under different hydrodynamic conditions. Both D. magna filtration and movement responded differently if the flow was laminar or if it was turbulent. In a laminar-dominated flow regime Daphnia filtration was enhanced up to 2.6 times that of a steady flow, but in the turbulent-dominated flow regime D. magna filtration was inhibited. In the laminar flow regime D. magna individuals moved freely in all directions, whereas in the turbulent flow regime they were driven by the streamlines of the flow. A model based on Daphnia-particle encountering revealed that the filtration efficiency in the laminar regime was driven by the length of the D. magna individuals and the shear rate imposed by the system.

AB - OBJECTIVES: An experimental study was performed with undergraduate nursing students in order to determine, between two methodologies, which is the best for learning standard precautions and precautions based on disease transmission mechanisms. METHODS: Students in the sample are stratified by performance, with the experimental group (49 students) being exposed to self-instruction and clinical simulation on the topic of standard precautions and special precautions according to disease transmission mechanisms. Conventional classes on the same topics were provided to the control group (49 students). RESULTS: The experimental group showed the best performance in the multiple-choice post-test of knowledge (p=0.002) and in the assessment of essay questions (p=0.043), as well as in the evaluation of a simulated scenario, in relation to the control group. CONCLUSIONS: This study demonstrates that it is possible to transfer some teaching subjects on the prevention of Healthcare Associated Infections (HAIs) to self-learning by means of virtual teaching strategies with good results. This allows greater efficiency in the allocation of teachers to clinical simulation or learning situations in the laboratory, where students can apply what they have learned in the self-instruction module. PMID- 29195211 TI - Supporting those who work and learn: A phenomenological research study. AB - AIM: With a shift in the United Kingdom's National Health Service to organisational learning and the local introduction of the Assistant Practitioner role to support the nursing workforce there was a broad need to understand the lived experiences of those who work and learn. METHOD: Hermeneutic phenomenology was the chosen methodology. A purposive sample of eight trainee assistant practitioners, four matrons, seven mentors and the practice development nurse participated in conversational interviews at intermittent points in the journey. RESULTS: A stepped process of analysis produced three over-arching super-ordinate themes which indicated that the transition to assistant practitioner is non linear and complex necessitating a change in knowledge and behaviour and the workplace culture must enable learning and role development. This paper focuses on supporting the journey which encompassed learning at university and learning in the workplace. CONCLUSION: Participants' stories demonstrated the presence of knowledgeable mentors and a learning culture enabled new roles to be supported.

PMID- 29195213 TI - Nursing students' emotional intelligence, coping styles and learning satisfaction in clinically simulated palliative care scenarios: An observational study. AB - BACKGROUND: Emotional intelligence is highly relevant in palliative care training, considering the coping styles used by nursing students. Clinical simulation provides the opportunity to evaluate these variables in a realistic and natural context. OBJECTIVES: To analyze the possible relation between emotional intelligence, coping styles and satisfaction with one's own self learning in nursing students participating in simulated scenarios related to palliative care at the end of life. METHODS: A descriptive, observational and correlational study of students in their second year of nursing at a Spanish University during the 2015/2016 academic year. Three variables were measured: emotional intelligence (Trait Meta-Mood Scale-24), coping styles (the Questionnaire for Dealing with Stress) and satisfaction with students' own learning (Student Satisfaction and Self-Confidence in Learning Scale, Spanish version CSLS-Sv). RESULTS: In total, 74 students participated in this study (ME: 20.3years). An association was found between satisfaction with learning, according to the EI attention subscale (in which the highest scores were registered) and two specific coping styles (FSP, with high scores and open emotional expression). CONCLUSIONS: Emotional intelligence and coping styles are desirable qualities in students, especially as they have a relevant role in satisfaction with one's own learning. Nonetheless, in part, these results depend on the characteristics of the educational activities designed, which is especially relevant in simulation applied to palliative care. PMID- 29195214 TI - Photoluminescent reduced graphene oxide quantum dots from latex of Calotropis gigantea for metal sensing, radical scavenging, cytotoxicity, and bioimaging in Artemia salina: A greener route. AB - In this work, we report the fabrication of green fluorescent reduced graphene oxide quantum dots (rGOQDs) from the latex of Calotropis gigantea by simple one step microwave assisted greener route. The latex of Calotropis gigantea calcined at 300 degrees C and its ethanolic extract is used for the synthesis of QDs, The rGOQDs showed particle size ranging from 2 to 8nm and it exhibited green fluorescent in longer UV region at 360-520nm. The rGOQDs graphitic nature was confirmed by RAMAN and XRD analysis. The FTIR, XPS demonstrate that presence of functional groups such as CO, COC, -OH, hence it's addressing them as rGOQDs. It is used to design the greener and economically adopted fluorescent probe for the detection of Pb2+ ions. It provides simple and appropriate for the selective and sensitive detection of Pb2+ ions in water purification process. It also trapped the free radicals and neutralized that and act as an excellent radical scavenger in DPPH radical scavenging assessment. These rGOQDs showed excellent biocompatibility on brine shrimp nauplii (Artemia salina) up to 160MUg/mL for 24h incubation. Furthermore, rGOQDS were demonstrated as fluorescent bioimaging probe selectively in the inner digestion part of Artemia salina. In summary, stable, economically viable, highly biocompatible, greener method based rGOQDs were prepared for heavy metal ion detecting, radical scavenging, bioimaging applications which can play a vital role in the future nanotechnology-based biomedical field. PMID- 29195215 TI - Amberlite IR-120 (H) mediated "on water" synthesis of fluorescent Ruthenium(II) arene 8-hydroxyquinoline complexes for cancer therapy and live cell imaging. AB - A series of Ruthenium-Quinolinol complexes (3a-d &4a-d) has been synthesized by employing a simple, efficient and environmental friendly condition. Catalytic role of Amberlite IRA-120(H) has been demonstrated. The structures of the new compounds were elucidated by the analysis of spectroscopic data. The stability of these complexes was measured by UV spectroscopy & time dependent NMR spectroscopy. These newly developed complexes were represented as potential anticancer agent against human breast carcinoma cell line (MCF-7), human Epitheloid Cervix Carcinoma (HeLa), human lung adenocarcinoma epithelial cell line (A549) and human colon cancer cell line (Caco-2). Most of the ruthenium complexes showed higher anticancer activity in MCF-7, HeLa and Caco-2 cell lines than cisplatin. A high selectivity (9-28 folds) was observed with these newly developed organoruthenium compounds in human cancer cell lines (MCF-7, HeLa and Caco-2) with respect to normal fibroblast cell line (MRC-5). Complex [(eta6 hexamethylbenzene)RuCl(kappa2-O,N-5-chloro-HyQ)].Cl (4b), [(eta6 hexamethylbenzene)RuCl(kappa2-O,N-5,7-dibromo-HyQ)].Cl (4c) and [(eta6 hexamethylbenzene)RuCl(kappa2-O,N-5-chloro-7-iodo-HyQ)].Cl (4d) exhibited best cytotoxicity profiles in three reported human cancer cell lines (MCF-7, HeLa, Caco-2). Cellular imaging study was also performed with these newly developed organoruthenium compounds. Compound 4c might be utilized for cancer theranostic agents because of its significant quantum yield in water, high potency, selectivity and high cellular uptake in cancer cell lines. PMID- 29195216 TI - Photo-induced toxicity of tungsten oxide photochromic nanoparticles. AB - We synthesised a new type of photochromic tungsten oxide nanoparticles, analysed their photocatalytic activity and carried out a thorough analysis of their effect on prokaryotic and eukaryotic organisms. Ultrasmall hydrated tungsten oxide nanoparticles were prepared by means of hydrothermal treatment of tungstic acid in the presence of polyvinylpyrrolidone as a template, stabiliser and growth regulator. Tungstic acid was synthesised through an ion-exchange method using sodium tungstate solution and a strongly acidic cation exchange resin. Upon illumination, photochromic nanoparticles of WO3 were shown to increase greatly their toxicity against both bacterial (both gram-positive and gram-negative - P. aeruginosa, E. coli and S. aureus) and mammalian cells (primary mouse embryonic fibroblasts); under the same conditions, fungi (C. albicans) were less sensitive to the action of tungsten oxide nanoparticles. UV irradiation of primary mouse fibroblasts in the presence of WO3 nanoparticles demonstrated a time- and dose dependent toxic effect, the latter leading to a significant decrease in dehydrogenase activity and an increase in the number of dead cells. WO3 nanoparticles were photocatalytically active under both UV light and even diffused daylight filtered through a window glass, leading to indigo carmine organic dye discolouration. The obtained experimental data not only show good prospects for biomedical applications of tungsten trioxide, but also demonstrate the need for clear control of biosafety when it is used in various household materials and appliances. PMID- 29195217 TI - Effects of posture and anatomical location on inter-recti distance measured using ultrasound imaging in parous women. AB - STUDY DESIGN: Cross-sectional repeated measures. OBJECTIVES: To quantify the effects of posture and measurement site on the inter-recti distance (IRD) and investigate the reliability of IRD measurement using ultrasound imaging in different postures. BACKGROUND: The linea alba connects the rectus abdominis muscles anteriorly and the width is known as the IRD. The IRD is usually measured in crook-lying and is the primary outcome measure to assess for a divarication of recti abdominis (DRA). The effects of posture and measurement site on the IRD have not been investigated. METHODS: Ultrasound imaging was used to measure IRD in 41 women >=8 weeks postpartum. The IRD was measured at three sites (superior umbilicus, umbilicus and inferior-umbilicus), in three postures (crook-lying, sitting and standing), and repeated one-week later. The effects of posture and site were investigated using one-way ANOVAs. Reliability was analysed using Intraclass correlation coefficients (ICCs), Bland Altman analyses, standard error of measurement and minimal detectable change. RESULTS: The IRD was wider when standing vs. lying at both the superior-umbilicus and umbilicus by 0.30 cm (95% CI 0.21 to 0.39) and 0.20 cm (0.11-0.30) respectively (p < 0.001). Measurements at the inferior-umbilicus were, on average, 1.6 and 2.1 cm narrower than superior umbilicus and umbilicus sites, respectively (p < 0.001). There was high intra rater reliability within-session (ICC3.3) and between-session (ICC3.1) at all sites measured. CONCLUSION: The IRD can be measured reliably at all sites and postures. The IRD is wider at superior-umbilicus and umbilicus when upright compared with lying. There is a difference in IRD between all sites measured. PMID- 29195218 TI - Nucleic acid-based electrochemical nanobiosensors. AB - The detection of biomarkers using sensitive and selective analytical devices is critically important for the early stage diagnosis and treatment of diseases. The synergy between the high specificity of nucleic acid recognition units and the great sensitivity of electrochemical signal transductions has already shown promise for the development of efficient biosensing platforms. Yet nucleic-acid based electrochemical biosensors often rely on target amplification strategies (e.g., polymerase chain reactions) to detect analytes at clinically relevant concentration ranges. The complexity and time-consuming nature of these amplification methods impede moving nucleic acid-based electrochemical biosensors from laboratory-based to point-of-care test settings. Fortunately, advancements in nanotechnology have provided growing evidence that the recruitment of nanoscaled materials and structures can enhance the biosensing performance (particularly in terms of sensitivity and response time) to the level suitable for use in point-of-care diagnostic tools. This Review highlights the significant progress in the field of nucleic acid-based electrochemical nanobiosensing with the focus on the works published during the last five years. PMID- 29195219 TI - Nanoconjugates of ferrocene and carbon-encapsulated iron nanoparticles as sensing platforms for voltammetric determination of ceruloplasmin in blood. AB - The nanoparticles comprising of iron core and carbon shell were decorated with ferrocene derivatives: ferrocenecarboxaldehyde (Fc-1) and ferrocenecarboxaldehyde oxime (Fc-2). A microdrop of suspension of the nanoconjugate was placed on a glassy-carbon electrode to prepare the recognition/sensing layer. Drying and purification of the sensing layer resulted in a well-defined and stable square wave voltammogram of the ferrocene moiety. The height of the voltammetric peak increased in the presence of ceruloplasmin. That increase was linearly dependent on the logarithmic concentration of ceruloplasmin in blood. The applied external magnetic field was a factor which yielded better sensitivity and repeatability of the sensor response. The linearity of sensor response was found to be between 0.001 and 10MUgdL-1 and 0.05-10MUgdL-1 for both nanoconjugates: Fe@C-Fc-1 and Fe@C-Fc-2, in the presence and absence of the magnet, respectively. The obtained detection limit (LOD) for Fe@C-Fc-1 was found to be 0.60 and 0.10MUgdL-1 in the absence and presence of magnetic field, respectively, whilst for Fe@C-Fc-2 was 0.4 and 0.07MUgdL-1 in the absence and presence of a magnet, respectively. The proposed method is selective because the presence of common antioxidants in blood did not interfere significantly with the determination of the concentration of ceruloplasmin. PMID- 29195220 TI - A comprehensive combined experimental and computational framework for pre clinical wear simulation of total knee replacements. AB - A more robust pre-clinical wear simulation framework is required in order to simulate wider and higher ranges of activities, observed in different patient populations such as younger more active patients. Such a framework will help to understand and address the reported higher failure rates for younger and more active patients (National_Joint_Registry, 2016). The current study has developed and validated a comprehensive combined experimental and computational framework for pre-clinical wear simulation of total knee replacements (TKR). The input mechanical (elastic modulus and Poisson's ratio) and wear parameters of the moderately cross-linked ultra-high molecular weight polyethylene (UHMWPE) bearing material were independently measured from experimental studies under realistic test conditions, similar to the loading conditions found in the total knee replacements. The wear predictions from the computational wear simulation were validated against the direct experimental wear measurements for size 3 Sigma curved total knee replacements (DePuy, UK) in an independent experimental wear simulation study under three different daily activities; walking, deep squat, and stairs ascending kinematic conditions. The measured compressive mechanical properties of the moderately cross-linked UHMWPE material were more than 20% lower than that reported in the literature under tensile test conditions. The pin on-plate wear coefficient of moderately cross-linked UHMWPE was significantly dependant of the contact stress and the degree of cross-shear at the articulating surfaces. The computational wear predictions for the TKR from the current framework were consistent and in a good agreement with the independent full TKR experimental wear simulation measurements, with 0.94 coefficient of determination of the framework. In addition, the comprehensive combined experimental and computational framework was able to explain the complex experimental wear trends from the three different daily activities investigated. Therefore, such a framework can be adopted as a pre-clinical simulation approach to optimise different designs, materials, as well as patient's specific total knee replacements for a range of activities. PMID- 29195221 TI - Comparison of ballistic impact effects between biological tissue and gelatin. AB - Gelatin is commonly used in ballistic testing as substitute for biological tissue. Comparison of ballistic impact effects produced in the gelatin and living tissue is lacking. The work in this paper was aimed to compare the typical ballistic impact effects (penetration trajectory, energy transfer, temporary cavity) caused by 4.8mm steel ball penetrating the 60kg porcine hind limbs and 10wt% gelatin. The impact event in the biological tissue was recorded by high speed flash X-ray machine at different delay time, while the event in the gelatin continuously recorded by high speed video was compared to that in the biological tissue. The collected results clearly displayed that the ballistic impact effects in the muscle and gelatin were similar for the steel ball test; as for instance, the projectile trajectory in the two targets was basically similar, the process of energy transfer was highly coincident, and the expansion of temporary cavity followed the same pattern. This study fully demonstrated that choosing gelatin as muscle simulant was reasonable. However, the maximum temporary cavity diameter in the gelatin was a little larger than that in the muscle, and the expansion period of temporary cavity was longer in the gelatin. Additionally, the temporary cavity collapse process in the two targets followed different patterns, and the collapse period in the gelatin was two times as long as that in the muscle. PMID- 29195222 TI - PAH (Polycyclic Aromatic Hydrocarbon) bioaccumulation and PAHs/shell weight index in Ruditapes philippinarum (Adams & Reeve, 1850) from the Vallona lagoon (northern Adriatic Sea, NE Italy). AB - The Vallona lagoon is a transitional area located in the Po River delta (NE, ITALY) traditionally exploited for Manila clam (Ruditapes philippinarum) farming. During 2007-2008, a pipeline was buried in the middle of the lagoon to connect an off-shore structure to facilities on land. PAH levels were monitored in Manila clams and sediments before, during and after the pipeline construction to assess the impact of the activities through the pattern of distribution of the PAH compounds. PAH bioaccumulation in clams displayed seasonal fluctuations with higher levels in autumnal and wintry surveys than in spring-summer. Principal component analysis applied to PAHs in clams highlighted a petrogenic input during ante operam period and a pyrolytic origin during the burying activities. On the contrary, sediment PAH concentrations resulted quite similar both among sites and periods. Biota-Sediment-Accumulation-Factor values also confirmed that sediments were not the major source of PAH pollution for clams in this study. The welfare of clams was examined through two physiological indices (condition index and survival in air) to check the effects of the activities on a commercial resource. Both physiological indices exhibited seasonal variations connected to natural endogenous and exogenous factors; however survival in air was the most sensitive index in highlighting the effects of the pipeline burying activities. Finally, to ensure that PAH bioavailability assessment was not affected by seasonal variation of soft tissues of molluscs, PAHs/shell weight index was applied. Higher levels of this index were observed before and during the burying activities, whilst, after that, values significantly lowered. Moreover, the normalization enabled us to highlight the PAH uptake from clams in some particular periods and to compare different populations in a long-term biomonitoring program with data obtained from different periods of the year. PMID- 29195223 TI - Dissipation behaviour, residue distribution and dietary risk assessment of tetraconazole and kresoxim-methyl in greenhouse strawberry via RRLC-QqQ-MS/MS technique. AB - 20% commercial suspension emulsion (SE) of (8% tetraconazole + 12% kresoxim methyl), as a pre-registered product in China, was firstly investigated under Chinese greenhouse-field conditions. A MWCNTs-based QuEChERS method for simultaneous determination of tetraconazole and kresoxim-methyl in strawberry was developed and validated via RRLC-QqQ-MS/MS. On basis of this method, the dissipation behaviours, residue distributions and dietary risk probability of these fungicides in strawberry were further investigated for food safety. The dissipations of tetraconazole and kresoxim-methyl followed first-order kinetics with the half-lives of 8.0-18.2 days. The highest residues (HRs) of these fungicides in the supervised trials at the pre-harvest interval (PHI, 3 days) were below 0.8970mgkg-1. The total national estimated daily intake (NEDI) of tetraconazole and kresoxim-methy in strawberry at the PHI 3day was 0.2784mg and 0.4031mg, respectively, based on Chinese dietary pattern and terminal residue distributions under good agricultural practices (GAP) conditions. The risk quotients (RQs) of tetraconazole and kresoxim-methy at PHI 3 days were below 82.7% and 1.6%, respectively, showing that the evaluated strawberry exhibited an acceptably low dietary risk to consumers. The current study could not only guide reasonable usage of the formulation, but also facilitate the setting of maximum residue limits (MRLs) of tetraconazole in strawberry. PMID- 29195224 TI - Combined application of compost and Bacillus sp. CIK-512 ameliorated the lead toxicity in radish by regulating the homeostasis of antioxidants and lead. AB - Lead (Pb) contamination is ubiquitous and usually causes toxicity to plants. Nevertheless, application of compost and plant growth promoting rhizobacteria synergistically may ameliorate the Pb toxicity in radish. The present study assessed the effects of compost and Bacillus sp. CIK-512 on growth, physiology, antioxidants and uptake of Pb in contaminated soil and explored the possible mechanism for Pb phytotoxicity amelioration. Treatments comprised of un inoculated control, compost, CIK-512, and compost + CIK-512; plants were grown in soil contaminated with Pb (500mgkg-1) and without Pb in pot culture. Lead caused reduction in shoot dry biomass, photosynthetic rate, stomatal conductance, relative water contents, whereas enhanced root dry biomass, ascorbate peroxidase, catalase, malondialdehyde and electrolyte leakage in comparison with non contaminated control. Plants inoculated with strain CIK-512 and compost produced significantly higher dry biomass, photosynthetic rate and stomatal conductance in normal and contaminated soils. Bacterial strain CIK-512 and compost synergy improved growth and physiology of radish in contaminated soil possibly through homeostasis of antioxidant activities, reduced membrane leakage and Pb accumulation in shoot. Possibly, Pb-induced production of reactive oxygen species resulted in increased electrolyte leakage and malondialdehyde contents (r = 0.88 0.92), which led to reduction in growth (r = -0.97) and physiology (r = -0.38 to 0.80), however, such negative effects were ameliorated by the regulation of antioxidants (r = 0.78-0.87). The decreased activity of antioxidants coupled with Pb accumulation in aerial part of the radish indicates the Pb-phytotoxicity amelioration through synergistic application of compost and Bacillus sp. CIK-512. PMID- 29195225 TI - Stigma and functional disability in relation to marriage and employment in young people with epilepsy in rural Tanzania. AB - PURPOSE: To assess the impact of childhood epilepsy on social transitioning outcomes for young people with epilepsy (YPWE) living in Tanzania, and to explore influences on these outcomes. METHODS: At six years from baseline, we followed up 84 YPWE and 79 age- sex- and village- matched controls recruited into a case control study of childhood epilepsy in rural northern Tanzania. Data were collected from interviews with young people and their carers using a structured questionnaire. Perceived stigma was evaluated using the Kilifi Stigma Score and functional disability using the Barthel Index (BI). The effects of age, gender, functional disability and stigma on selected markers of social transitioning (education, employment and relationships) were estimated using multivariable modelling. RESULTS: Fewer YPWE than controls were in an intimate relationship (42.3% vs. 76.9%) or in education or paid employment (33.3% vs. 91.1%) and they reported elevated perceived stigma scores (27.4% vs. 3.8%). Among YPWE, a positive education or employment outcome was predicted by a lower seizure frequency (adjusted OR 3.79) and a higher BI score (adj. OR 12.12); a positive relationship outcome was predicted by a higher BI score (adj. OR 45.86) and being male (adj. OR 8.55). CONCLUSION: YPWE were more likely to experience adverse employment, educational and relationship outcomes in the transition to adult life than controls, with the greatest disadvantage experienced by females, those with greater functional disability and those with poorer seizure control. Markers of social transitioning should be included in any prospective evaluation of interventions designed to support these groups. PMID- 29195226 TI - The Viral Hypothesis of Mesial Temporal Lobe Epilepsy - Is Human Herpes Virus-6 the Missing Link? A systematic review and meta-analysis. AB - PURPOSE: Mesial temporal lobe epilepsy (MTLE) is a common epileptic disorder. Although likely multifactorial, the mechanisms underlying the etiology and pathogenesis of the disease remains unknown in majority of patients. Viruses, particularly Human Herpes Virus 6A and B (HHV-6), two neurotropic herpes viruses, have been implicated in MTLE due to their ubiquitous nature and ability to establish lifelong latency with risk of reactivation. However, the results of studies investigating this relationship are conflicting. This systematic review and meta-analysis was conducted to determine the relationship between HHV-6 DNA (not specifying if A or B) in brain tissue and MTLE based on the current evidence. METHOD: Two independent assessors carried out a comprehensive electronic search to identify all relevant studies. Both fixed- and random effects models were used to determine the overall odds ratio. RESULTS: A total of 10 studies met the inclusion criteria for the systematic review and eight for the meta-analysis. In 19.6% of all MTLE patients HHV-6 DNA was detected in brain tissue compared to 10.3% of all controls (p >0.05). The pooled odds ratio of HHV 6 positive cases in MTLE patients was 2.016 [95%-CI: 1.16-3.50] in the fixed effect model. CONCLUSION: The results of this meta-analysis indicate an association between HHV-6 DNA and MTLE surgically resected tissue samples, unspecified if A or B or both. However, the casual relationship and possible pathological role of HHV-6 in MTLE are yet to be elucidated. This study's results provide a basis for future studies continuing the investigation into pathological implications of HHV-6.

AB - The neuroendocrine glycoprotein chromogranin A is a useful biomarker for stress in humans. Chromogranin A epitopes catestatin and vasostatin can be measured in dogs using radioimmunoassays. The objective of this study was to evaluate catestatin and vasostatin as canine stress biomarkers in a clinical setting. Blood and saliva were collected from 33 healthy dogs that were familiar with sampling procedures and the animal hospital environment (control group) and 30 healthy dogs that were unacquainted (stress group). During sampling, stress behavior was scored by the same observer using visual analog scale (VAS). Plasma was analyzed for catestatin and vasostatin, serum for cortisol, and saliva for catestatin. Differences between groups were analyzed using two-sample t-tests and P<0.05 was considered significant. Stress behavior VAS score in the control group was significantly lower than in the stress group during blood (P=0.002) and saliva (P=0.0009) sampling. Serum cortisol and saliva catestatin concentrations in the stress group were higher than the control group (P=0.003 and P<0.0001, respectively). Serum cortisol concentrations were correlated with those of saliva (r=0.34, P=0.04) and plasma catestatin (r=0.29, P=0.03). Plasma catestatin and vasostatin did not differ significantly between groups. In conclusion, concentrations of saliva catestatin, and serum cortisol, and stress behavior VAS scores were significantly higher in the stress group. The results indicate that saliva catestatin may be useful as a biomarker for acute psychological stress in dogs.

AB - European brown hare syndrome virus (EBHSV) was detected in a faecal swab collected from a wolf carcass in Northern Italy. The full-length genome of the EBHSV WOLF/17/2016/ITA strain was determined. In the VP60 capsid gene, the wolf strain displayed the highest genetic identity (99.2-99.1% nucleotide and 99.6 99.7% amino acid) with two EBHSV strains recently found in the intestinal content of a red fox and in the spleen and liver of a hare in Northern Italy. This finding poses interrogatives on the potential role of carnivores as EBHSV passive carriers, favoring the introduction and spread of the virus among different hare populations.

AB - The efficacy and toxicity of drugs depend not only on their potency but also on their ability to reach the target sites in preference to non-target sites. In this regards destabilization of delivery vehicles induced by light can be an effective strategy for enhancing drug delivery with spatial and temporal control. Herein we demonstrate that the photoinduced isomerization from closed (hydrophobic) to open isomeric form (hydrophilic) of a novel DHI encapsulated in liposome leads to potential light-controlled drug delivery vehicles. We have used steady state and picosecond resolved dynamics of a drug 8-anilino-1 naphthalenesulfonic acid ammonium salt (ANS) incorporated in liposome to monitor the efficacy of destabilization of liposome in absence and presence UVA irradiation. Steady state and picosecond resolved polarization gated spectroscopy including the well-known strategy of solvation dynamics and Forster resonance energy transfer; reveal the possible mechanism out of various phenomena involved in destabilization of liposome. We have also investigated the therapeutic efficacy of doxorubicin (DOX) delivery from liposome to cervical cancer cell line HeLa. The FACS, confocal fluorescence microscopic and MTT assay studies reveal an enhanced cellular uptake of DOX leading to significant reduction in cell viability (~40%) of HeLa followed by photoresponsive destabilization of liposome. Our studies successfully demonstrate that these DHI encapsulated liposomes have potential application as a smart photosensitive drug delivery system.

AB - Recent advances in stem cell research and nanotechnology have significantly influenced the landscape of tissue engineering and regenerative medicine. Precise and reproducible control of the fate of stem cells and their lineage specification have, therefore, become more crucial than ever for the success of stem cell-based technologies. Extensive research has been geared towards developing materials that are capable of mimicking the physiological microenvironment of stem cells and at the same time, controlling their eventual fate. An interesting example of these materials is two-dimensional graphene and its related derivatives. A high specific surface area coupled with superior chemical stability, biocompatibility, and flexibility in functionalization render graphene-based nanomaterials one of the most exciting platforms for tissue engineering and regenerative medicine applications, especially for stem cell growth, proliferation, and differentiation. In this review, we discuss the love hate relationship between stem cells and graphene-based nanomaterials in tissue engineering and regenerative medicine. We first discuss the role and importance of stem cells in tissue engineering and regenerative medicine. We then highlight the use of nanomaterials for stem cell control, the interaction between stem cells and graphene nanomaterials as well as their biocompatibility, biodistribution, and biodegradability considerations. We also offer our perspectives on the various challenges and opportunities facing the use of graphene and its derivatives for stem cell growth and differentiation. PMID- 29195231 TI - Early response to salt ions in maize (Zea mays L.). AB - Abscisic acid (ABA) regulates leaf growth and transpiration rate of plants exposed to salt stress. Despite the known fact that cell dehydration is instrumental for the modulation of ABA concentrations when NaCl is high in the external environment, it was never tested as to whether sodium (Na) or chlorine (Cl) also modulate ABA concentrations. To answer this question, a hydroponic study on maize (Zea mays) was established, by exposing plants to 50mM of sodium glucosamide or glucosamine chloride. The effect of both ions on ABA was investigated in an early stage before (i) the salt ions accumulated to toxic tissue concentrations and before (ii) cells dehydrated. This allowed studying early responses to Na and Cl separately, well before plants were stressed by these ions. Gas chromatography-mass spectrometry analysis was used to quantify ABA concentrations in roots and in leaves after a period of 2h after ion application. The transcript abundance of the key regulatory enzyme of the biosynthesis of ABA in maize, the 9-cis-epoxycarotenoid dioxygenase gene viviparous 14, was quantified via real-time quantitative-reverse-transcriptase polymerase-chain-reaction. The results reveal that Cl and Na induce the increase of leaf tissue ABA concentrations at two hours after plants were exposed to 50mM of the ions. Surprisingly, this effect was more pronounced in response to the Cl component. The increase in the guard-cell regulating ABA concentration correlated with a reduced transpiration. Mainly because of this result we suggest that the early accumulation of ABA is useful in maintaining cell turgor. PMID- 29195232 TI - Kaolin modulates ABA and IAA dynamics and physiology of grapevine under Mediterranean summer stress. AB - The foliar exogenous application of kaolin, a radiation-reflecting inert mineral, has proven to be an effective short-term climate change mitigation strategy for Mediterranean vineyards. In this work, we address the hypothesis that kaolin could improve both the hormonal dynamics and physiological responses of grapevines growing in Douro Region, northern Portugal. For this purpose, the leaf water potential, gas exchange and chlorophyll a fluorescence parameters were monitored, as well as the abscisic acid (ABA) and indole-3-acetic acid (IAA) quantification and immunolocalization were assessed. The study revealed a slight decrease in ABA and an increase in IAA in the kaolin treatment, which in turn were associated with the improvement of physiological performance. A month after spraying, kaolin improves the water potential respectively, 30% and 17% in the predawn and midday periods. Besides, plants treated with kaolin showed higher values of stomatal conductance, net CO2 assimilation rate and intrinsic water use efficiency. Kaolin also ameliorates the effective PSII efficiency (67%), as well as the maximum quantum efficiency of photosystem II and the photosynthetic electron transport rate (>73%). These results were consistent with the higher photochemical quenching and the lower non-photochemical quenching observed in treated leaves and with the better performance obtained by the JIP test parameters. Physiological and hormonal analysis confirmed that kaolin effectively enhance grapevine summer stress tolerance. PMID- 29195234 TI - Aesthetic Management of Upper and Midface Trauma.

AB - Periodontitis is a local inflammatory environment with dysregulation of host responses, which results in destruction of periodontal tissues. Mesenchymal stem cells (MSCs) have been proven to play important roles in tissue regeneration by serving as progenitor cells, but its therapeutic outcomes are yet, evaluated variable and unpredictable because of the influence of local inflammation. Acetylsalicylic acid (ASA) has been reported to benefit for MSCs in terms of inflammation control and tissue regeneration. In this study, we aimed to explore the effect of bone marrow mesenchymal stem cells (BMMSCs) pretreated with ASA (ASA-BMMSCs) on periodontal bone repair in a ligature and bacteria-induced periodontitis model in rats. We show herein that, ASA-BMMSCs treatment reduced inflammatory infiltration and alveolar bone loss in periodontitis rats, reflected by immunohistochemistry staining of OPG/RANK-L and Micro-CT. Levels of TNF-alpha and IL-17 decreased while IL-10 increased after the treatment of ASA-BMMSCs in periodontitis rats. In addition, less osteoclasts number was detected in ASA BMMSCs treated group. In vitro study showed that ASA facilitated BMMSCs proliferation and differentiation, which might explain the reduced bone loss in periodontitis. These results together suggest that local application of ASA BMMSCs in periodontal lesion sites is capable of improving inflammatory microenvironment, promoting alveolar bone regeneration, thus leading to a recovery of periodontal homeostasis. Besides, this study also provides us a new idea that a combined application of ASA and BMMSCs may be a novel approach for periodontitis treatment and periodontal bone regeneration.

AB - : BACKGROUND AND STUDY AIMS : Endoscopic techniques have demonstrated their effectiveness in metabolic surgery, notably through a gastrointestinal (GI) liner, with a less invasive approach than conventional surgery. Our study evaluates the safety and efficacy of endoscopic GI anastomosis (EGIA) using a lumen-apposing stent to secure the anastomosis. MATERIALS AND METHODS : EGIA was performed using the transgastric approach with a two-channel endoscope with a novel stent (Cousin Biotech). First, a safety study with a follow-up of 12 months was performed on five piglets. Then, metabolic changes were investigated in a minipig model (n = 10) before and after EGIA or open GIA (OGIA). RESULTS: EGIA was technically successful with no complications observed during clinical monitoring. Endoscopic and postmortem examinations during the second part of study showed a secure anastomosis between the stomach and the intestinal limb in all except one minipig. Both minipigs subjected to EGIA and those in the control group (OGIA) exhibited increased postprandial glucagon-like peptide-1 (GLP-1) production (incretin secretion) and impaired D-xylose absorption (malabsorption effect). CONCLUSION : Performing EGIA with this dedicated stent appears safe, technically feasible, durable, and reproducible in providing a simple and effective endoscopic GI bypass capable of ensuring metabolic effect.

AB - Biosimilars are subject to the efficiency evaluation according to section 106 Social Code Book Five (SGB V). The specific evaluation method influences the physician's prescription behaviour. In the case of an individual prescription limit evaluation (Richtgrobetaenprufung), the prescription of biosimilars would usually not result in recourse but, as a start, in the initiation of the evaluation proceedings. Starting from 2017, the individual prescription limit evaluation will be cancelled. The active ingredient evaluation (Wirkstoffprufung) expected instead at a regional level may provide for biosimilar to original drug ratios and result in recourses if these ratios are missed. First agreements on specific evaluation proceedings at a regional level are expected for this year. PMID- 29195263 TI - ? PMID- 29195264 TI - ? PMID- 29195265 TI - ? PMID- 29195266 TI - ?

AB - OBJECTIVE: Few studies have compared transsphenoidal endoscopic (TE) and transsphenoidal microscopic (TM) techniques for the treatment of craniopharyngiomas. DESIGN: We performed a systematic review of published series. The results were stratified in two time periods from 1995 to 2016. RESULTS: A total of 48 articles and 1,186 patients met the inclusion criteria. Overall, 60% of endoscopic cases were supradiaphragmatic, and 76% of microsurgical cases were infradiaphragmatic. Mean tumor size was 3 cm and 2.4 cm in the TE and TM series, respectively (p = 0.008). Total resection rate was similar (66%) between TE and TM. Considering the surgical outcome for different tumor locations, total resection rate was slightly higher in the TE for supradiaphragmatic lesions (59% versus 42.5%; p = 0.26). Recurrence rate was higher in the endoscopic series (21.7% versus 12%). Mortality and the overall complication rates were similar (p = 0.84). However, hydrocephalus (7.6%) and cognitive dysfunction (15.8%) were more common in TE, and meningitis (6%) and endocrinologic complications were more common in the TM series. In the past 6 years, the rate of cerebrospinal fluid leak in TE was significantly lower (13%) and was comparable between TE and TM. CONCLUSION: Both techniques appear comparable for infradiaphragmatic lesions; however, TE seems to yield better results for supradiaphragmatic tumors. In conclusion, more complex lesions with difficult locations can be effectively treated with endoscopic surgery.

PMID- 29195270 TI - Compositional Proteomics: Effects of Spatial Constraints on Protein Quantification Utilizing Isobaric Tags. AB - Mass spectrometry (MS) has become an accessible tool for whole proteome quantitation with the ability to characterize protein expression across thousands of proteins within a single experiment. A subset of MS quantification methods (e.g., SILAC and label-free) monitor the relative intensity of intact peptides, where thousands of measurements can be made from a single mass spectrum. An alternative approach, isobaric labeling, enables precise quantification of multiple samples simultaneously through unique and sample specific mass reporter ions. Consequently, in a single scan, the quantitative signal comes from a limited number of spectral features (<=11). The signal observed for these features is constrained by automatic gain control, forcing codependence of concurrent signals. The study of constrained outcomes primarily belongs to the field of compositional data analysis. We show experimentally that isobaric tag proteomics data are inherently compositional and highlight the implications for data analysis and interpretation. We present a new statistical model and accompanying software that improves estimation accuracy and the ability to detect changes in protein abundance. Finally, we demonstrate a unique compositional effect on proteins with infinite changes. We conclude that many infinite changes will appear small and that the magnitude of these estimates is highly dependent on experimental design.

AB - A soft porous Zn(II)-MOF (1) displays distinctive three-step hysteretic breathing behavior under ethane gas pressure at ambient temperatures. In situ single crystal X-ray diffraction analysis was carried out at 298 K using an environmental gas cell in order to elucidate the different porous forms of the breathing framework under ethane gas. The three different phases were further characterized by pressure-gradient differential scanning calorimetry and variable pressure powder X-ray diffraction analysis. PMID- 29195272 TI - Multivalent Antimicrobial Polymer Nanoparticles Target Mycobacteria and Gram Negative Bacteria by Distinct Mechanisms. AB - Because of the emergence of antimicrobial resistance to traditional small molecule drugs, cationic antimicrobial polymers are appealing targets. Mycobacterium tuberculosis is a particular problem, with multi- and total drug resistance spreading and more than a billion latent infections globally. This study reports nanoparticles bearing variable densities of poly(dimethylaminoethyl methacrylate) and the unexpected and distinct mechanisms of action this multivalent presentation imparts against Escherichia coli versus Mycobacterium smegmatis (model of M. tuberculosis), leading to killing or growth inhibition, respectively. A convergent "grafting to" synthetic strategy was used to assemble a 50-member nanoparticle library, and using a high-throughput screen identified that only the smallest (2 nm) particles were stable in both saline and complex cell media. Compared with the linear polymers, the nanoparticles displayed two- and eight-fold enhancements in antimicrobial activity against M. smegmatis and E. coli, respectively. Mechanistic studies demonstrated that the antimicrobial particles were bactericidal against E. coli due to rapid disruption of the cell membranes. Conversely, against M. smegmatis the particles did not lyse the cell membrane but rather had a bacteriostatic effect. These results demonstrate that to develop new polymeric antituberculars the widely assumed, broad spectrum, membrane-disrupting mechanism of polycations must be re-evaluated. It is clear that synthetic nanomaterials can engage in more complex interactions with mycobacteria, which we hypothesize is due to the unique cell envelope at the surface of these bacteria.

AB - We present an open-source, interactive program named Proteoform Suite that uses proteoform mass and intensity measurements from complex biological samples to identify and quantify proteoforms.

It is applied here to reveal systemic proteoform variations in the yeast response to salt stress. PMID- 29195274 TI - Self-Assembly of Telechelic Tyrosine End-Capped PEO Star Polymers in Aqueous Solution. AB - We investigate the self-assembly of two telechelic star polymer-peptide conjugates based on poly(ethylene oxide) (PEO) four-arm star polymers capped with oligotyrosine. The conjugates were prepared via N-carboxy anhydride-mediated ring opening polymerization from PEO star polymer macroinitiators. Self-assembly occurs above a critical aggregation concentration determined via fluorescence probe assays. Peptide conformation was examined using circular dichroism spectroscopy. The structure of self-assembled aggregates was probed using small angle X-ray scattering and cryogenic transmission electron microscopy. In contrast to previous studies on linear telechelic PEO-oligotyrosine conjugates that show self-assembly into beta-sheet fibrils, the star architecture suppresses fibril formation and micelles are generally observed instead, a small population of fibrils only being observed upon pH adjustment. Hydrogelation is also suppressed by the polymer star architecture. These peptide-functionalized star polymer solutions are cytocompatible at sufficiently low concentration. These systems present tyrosine at high density and may be useful in the development of future enzyme or pH-responsive biomaterials. PMID- 29195276 TI - Short-range second order screened exchange correction to RPA correlation energies. AB - Direct random phase approximation (RPA) correlation energies have become increasingly popular as a post-Kohn-Sham correction, due to significant improvements over DFT calculations for properties such as long-range dispersion effects, which are problematic in conventional density functional theory. On the other hand, RPA still has various weaknesses, such as unsatisfactory results for non-isogyric processes. This can in parts be attributed to the self-correlation present in RPA correlation energies, leading to significant self-interaction errors. Therefore a variety of schemes have been devised to include exchange in the calculation of RPA correlation energies in order to correct this shortcoming. One of the most popular RPA plus exchange schemes is the second order screened exchange (SOSEX) correction. RPA + SOSEX delivers more accurate absolute correlation energies and also improves upon RPA for non-isogyric processes. On the other hand, RPA + SOSEX barrier heights are worse than those obtained from plain RPA calculations. To combine the benefits of RPA correlation energies and the SOSEX correction, we introduce a short-range RPA + SOSEX correction. Proof of concept calculations and benchmarks showing the advantages of our method are presented. PMID- 29195277 TI - Sub-500 fs electronically nonadiabatic chemical dynamics of energetic molecules from the S1 excited state: Ab initio multiple spawning study. AB - Energetic materials store a large amount of chemical energy. Different ignition processes, including laser ignition and shock or compression wave, initiate the energy release process by first promoting energetic molecules to the electronically excited states. This is why a full understanding of initial steps of the chemical dynamics of energetic molecules from the excited electronic states is highly desirable. In general, conical intersection (CI), which is the crossing point of multidimensional electronic potential energy surfaces, is well established as a controlling factor in the initial steps of chemical dynamics of energetic molecules following their electronic excitations. In this article, we have presented different aspects of the ultrafast unimolecular relaxation dynamics of energetic molecules through CIs. For this task, we have employed ab initio multiple spawning (AIMS) simulation using the complete active space self consistent field (CASSCF) electronic wavefunction and frozen Gaussian-based nuclear wavefunction. The AIMS simulation results collectively reveal that the ultrafast relaxation step of the best energetic molecules (which are known to exhibit very good detonation properties) is completed in less than 500 fs. Many, however, exhibit sub-50 fs dynamics. For example, nitro-containing molecules (including C-NO2, N-NO2, and O-NO2 active moieties) relax back to the ground state in approximately 40 fs through similar (S1/S0)CI conical intersections. The N3-based energetic molecule undergoes the N2 elimination process in 40 fs through the (S1/S0)CI conical intersection. Nitramine-Fe complexes exhibit sub-50 fs Fe-O and N-O bond dissociation through the respective (S1/S0)CI conical intersection. On the other hand, tetrazine-N-oxides, which are known to exhibit better detonation properties than tetrazines, undergo internal conversion in a 400-fs time scale, while the relaxation time of tetrazine is very long (about 100 ns). Many other characteristics of sub-500 fs nonadiabatic decay of energetic molecules are discussed. In the end, many unresolved issues associated with the ultrafast nonadiabatic chemical dynamics of energetic molecules are presented. PMID- 29195278 TI - Localization switching of a large object in a crowded cavity: A rigid/soft object prefers surface/inner positioning. AB - For living cells in the real world, a large organelle is commonly positioned in the inner region away from membranes, such as the nucleus of eukaryotic cells, the nucleolus of nuclei, mitochondria, chloroplast, Golgi body, etc. It contradicts the expectation by the current depletion-force theory in that the larger particle should be excluded from the inner cell space onto cell boundaries in a crowding media. Here we simply model a sizable organelle as a soft-boundary large particle allowing crowders, which are smaller hard spheres in the model, to intrude across its boundary. The results of Monte Carlo simulation indicate that the preferential location of the larger particle switches from the periphery into the inner region of the cavity by increasing its softness. An integral equation theory is further developed to account for the structural features of the model, and the theoretical predictions are found consistent with our simulation results.

AB - Accurate knowledge of transition dipole moment matrix elements is crucial since important parameters associated with the interaction of light with matter, such as emission and absorption line intensities, lifetimes, and Einstein coefficients, depend on these matrix elements. We report here an experimental study of the Na2 51Sigmag+<->A1Sigmau+ and 61Sigmag+<->A1Sigmau+ electronic transition dipole moments and their dependence on internuclear distance. We have measured absolute transition dipole matrix elements for ro-vibrational transitions of the Na2 51Sigmag+<->A1Sigmau+ and 61Sigmag+<->A1Sigmau+ electronic transitions using Autler-Townes and optical-optical double resonance spectroscopy, and we compare the results to ab initio theoretical values [A.

AB - A powerful tool for controlling interfacial properties and molecular architecture relies on the tailored adsorption of stimuli-responsive block copolymers onto surfaces. Here, we use computational and experimental approaches to investigate the adsorption behavior of thermally responsive polypeptide block copolymers (elastin-like polypeptides, ELPs) onto silica surfaces, and to explore the effects of surface affinity and micellization on the adsorption kinetics and the resultant polypeptide layers. We demonstrate that genetic incorporation of a silica-binding peptide (silaffin R5) results in enhanced adsorption of these block copolymers onto silica surfaces as measured by quartz crystal microbalance and ellipsometry. We find that the silaffin peptide can also direct micelle adsorption, leading to close-packed micellar arrangements that are distinct from the sparse, patchy arrangements observed for ELP micelles lacking a silaffin tag, as evidenced by atomic force microscopy measurements. These experimental findings are consistent with results of dissipative particle dynamics simulations. Wettability measurements suggest that surface immobilization hampers the temperature-dependent conformational change of ELP micelles, while adsorbed ELP unimers (i.e., unmicellized block copolymers) retain their thermally responsive property at interfaces. These observations provide guidance on the use of ELP block copolymers as building blocks for fabricating smart surfaces and interfaces with programmable architecture and functionality. PMID- 29195280 TI - Anomalous phase behavior of first-order fluid-liquid phase transition in phosphorus. AB - Although the existence of liquid-liquid phase transition has become more and more convincing, whether it will terminate at a critical point and what is the order parameter are still open. To explore these questions, we revisit the fluid-liquid phase transition (FLPT) in phosphorus (P) and study its phase behavior by performing extensive first-principles molecular dynamics simulations. The FLPT observed in experiments is well reproduced, and a fluid-liquid critical point (FLCP) at T = 3000 ~ 3500 K, P = 1.5-2.0 Kbar is found. With decreasing temperature from the FLCP along the transition line, the density difference (Deltarho) between two coexisting phases first increases from zero and then anomalously decreases; however, the entropy difference (DeltaS) continuously increases from zero. These features suggest that an order parameter containing contributions from both the density and the entropy is needed to describe the FLPT in P, and at least at low temperatures, the entropy, instead of the density, governs the FLPT. PMID- 29195281 TI - Thermodynamic framework for information in nanoscale systems with memory. AB - Information is represented by linear strings of symbols with memory that carry errors as a result of their stochastic nature. Proofreading and edition are assumed to improve certainty although such processes may not be effective. Here, we develop a thermodynamic theory for material chains made up of nanoscopic subunits with symbolic meaning in the presence of memory. This framework is based on the characterization of single sequences of symbols constructed under a protocol and is used to derive the behavior of ensembles of sequences similarly constructed. We then analyze the role of proofreading and edition in the presence of memory finding conditions to make revision an effective process, namely, to decrease the entropy of the chain. Finally, we apply our formalism to DNA replication and RNA transcription finding that Watson and Crick hybridization energies with which nucleotides are branched to the template strand during the copying process are optimal to regulate the fidelity in proofreading. These results are important in applications of information theory to a variety of solid state physical systems and other biomolecular processes. PMID- 29195282 TI - Virial coefficients of anisotropic hard solids of revolution: The detailed influence of the particle geometry. AB - We provide analytical expressions for the second virial coefficients of differently shaped hard solids of revolution in dependence on their aspect ratio. The second virial coefficients of convex hard solids, which are the orientational averages of the mutual excluded volume, are derived from volume, surface, and mean radii of curvature employing the Isihara-Hadwiger theorem. Virial coefficients of both prolate and oblate hard solids of revolution are investigated in dependence on their aspect ratio. The influence of one- and two dimensional removable singularities of the surface curvature to the mutual excluded volume is analyzed. The virial coefficients of infinitely thin oblate and infinitely long prolate particles are compared, and analytical expressions for their ratios are derived. Beyond their dependence on the aspect ratio, the second virial coefficients are influenced by the detailed geometry of the particles.

PMID- 29195284 TI - Dynamic principle for ensemble control tools. AB - Dynamical equations describing physical systems in contact with a thermal bath are commonly extended by mathematical tools called "thermostats." These tools are designed for sampling ensembles in statistical mechanics. Here we propose a dynamic principle underlying a range of thermostats which is derived using fundamental laws of statistical physics and ensures invariance of the canonical measure. The principle covers both stochastic and deterministic thermostat schemes. Our method has a clear advantage over a range of proposed and widely used thermostat schemes that are based on formal mathematical reasoning. Following the derivation of the proposed principle, we show its generality and illustrate its applications including design of temperature control tools that differ from the Nose-Hoover-Langevin scheme.

AB - The dynamics of nanoscale clusters can be distinct from macroscale behavior described by continuum formalisms. For diffusion of 2D clusters of N atoms in homoepitaxial systems mediated by edge atom hopping, macroscale theory predicts simple monotonic size scaling of the diffusion coefficient, DN ~ N-beta, with beta = 3/2. However, modeling for nanoclusters on metal(100) surfaces reveals that slow nucleation-mediated diffusion displaying weak size scaling beta < 1 occurs for "perfect" sizes Np = L2 and L(L+1) for integer L = 3,4,... (with unique square or near-square ground state shapes), and also for Np+3, Np+4,.... In contrast, fast facile nucleation-free diffusion displaying strong size scaling beta ~ 2.5 occurs for sizes Np+1 and Np+2. DN versus N oscillates strongly between the slowest branch (for Np+3) and the fastest branch (for Np+1). All branches merge for N = O(102), but macroscale behavior is only achieved for much larger N = O(103). This analysis reveals the unprecedented diversity of behavior on the nanoscale.

Chem. Phys. 140, 18A509 (2014)], which was initially applied to range-separated ground-state-density-functional Hamiltonians, is adapted in this work to ghost-interaction-corrected (GIC) range separated ensemble density-functional theory (eDFT) for excited states. While standard extrapolations rely on energies that decay as MU-2 in the large range separation-parameter MU limit, we show analytically that (approximate) range separated GIC ensemble energies converge more rapidly (as MU-3) towards their pure wavefunction theory values (MU -> +infinity limit), thus requiring a different extrapolation correction. The purpose of such a correction is to further improve on the convergence and, consequently, to obtain more accurate excitation energies for a finite (and, in practice, relatively small) MU value. As a proof of concept, we apply the extrapolation method to He and small molecular systems (viz., H2, HeH+, and LiH), thus considering different types of excitations such as Rydberg, charge transfer, and double excitations. Potential energy profiles of the first three and four singlet Sigma+ excitation energies in HeH+ and H2, respectively, are studied with a particular focus on avoided crossings for the latter. Finally, the extraction of individual state energies from the ensemble energy is discussed in the context of range-separated eDFT, as a perspective.

AB - The accuracy of the density of wave function methods and Kohn-Sham (KS) density functionals is studied using moments of the density, ?rn?=? rho rrndtau=?0infinity4pir2rho(r)rndr,where n=-1,-2,0,1,2,and 3 provides information about the short- and long-range behavior of the density. Coupled cluster (CC) singles, doubles, and perturbative triples (CCSD(T)) is considered as the reference density. Three test sets are considered: boron through neon neutral atoms, two and four electron cations, and 3d transition metals. The total density and valence only density are distinguished by dropping appropriate core orbitals. Among density functionals tested, CAMQTP00 and omegaB97x show the least deviation for boron through neon neutral atoms. They also show accurate eigenvalues for the HOMO indicating that they should have a more correct long-range behavior for the density. For transition metals, some density functional approximations outperform some wave function methods, suggesting that the KS determinant could be a better starting point for some kinds of correlated calculations. By using generalized many-body perturbation theory (MBPT), the convergence of second-, third-, and fourth-order KS-MBPT for the density is addressed as it converges to the infinite order coupled cluster result. For the transition metal test set, the deviations in the KS density functional theory methods depend on the amount of exact exchange the functional uses. Functionals with exact exchange close to 25% show smaller deviations from the CCSD(T) density. PMID- 29195288 TI - Nucleation mechanism of clathrate hydrates of water-soluble guest molecules. AB - The mechanism of nucleation of clathrate hydrates of a water-soluble guest molecule is rigorously investigated with molecular dynamics (MD) simulations. Results from forward flux sampling, committor probability analysis, and twenty straightforward MD trajectories were combined to create a comprehensive understanding of the nucleation mechanism. Seven different classes of order parameters with a total of 33 individual variants were studied. We rank and evaluate the efficacy of prospective reaction coordinate models built from these order parameters and linear combinations thereof. Order parameters based upon water structuring provide a better approximation of the reaction coordinate than those based upon guest structuring. Our calculations suggest that the transition state is characterized by 2-3 partial, face-sharing 512 cages that form a structural motif observed in the structure II crystal. Further simulations show that once formed, this structure significantly affects the ordering of vicinal guest molecules, likely leading to hydrate nucleation. Our results contribute to the current understanding of the water-guest interplay involved in hydrate nucleation and have relevance to hydrate-based technologies that use water soluble guest molecules (e.g., tetrahydrofuran) in mixed hydrate systems. PMID- 29195289 TI - A variational conformational dynamics approach to the selection of collective variables in metadynamics. AB - In this paper, we combine two powerful computational techniques, well-tempered metadynamics and time-lagged independent component analysis. The aim is to develop a new tool for studying rare events and exploring complex free energy landscapes. Metadynamics is a well-established and widely used enhanced sampling method whose efficiency depends on an appropriate choice of collective variables. Often the initial choice is not optimal leading to slow convergence. However by analyzing the dynamics generated in one such run with a time-lagged independent component analysis and the techniques recently developed in the area of conformational dynamics, we obtain much more efficient collective variables that are also better capable of illuminating the physics of the system. We demonstrate the power of this approach in two paradigmatic examples. PMID- 29195290 TI - Static field-gradient polarizabilities of small atoms and molecules at finite temperature. AB - In this work, we propose new field-free estimators of static field-gradient polarizabilities for finite temperature path-integral Monte Carlo method. Namely, dipole-quadrupole polarizability A, dipole-dipole-quadrupole polarizability B, and quadrupole-quadrupole polarizability C are computed for several up to two electron systems: H, H-, He, Li+, Be2+, Ps2, PsH, H2+, H2, H3+, and HeH+. We provide complementary data for ground state electronic properties within the adiabatic approximation and demonstrate good agreement with available values in the literature. More importantly, we present fully non-adiabatic results from 50 K to 1600 K, which allow us to analyze and discuss strong thermal coupling and rovibrational effects in total field-gradient polarizabilities. These phenomena are most relevant but clearly overlooked, e.g., in the construction of modern polarizable force field models. However, our main purpose is demonstrating the accuracy and simplicity of our approach in a problem that is generally challenging. PMID- 29195291 TI - Communication: Coordinate-dependent diffusivity from single molecule trajectories. AB - Single-molecule observations of biomolecular folding are commonly interpreted using the model of one-dimensional diffusion along a reaction coordinate, with a coordinate-independent diffusion coefficient. Recent analysis, however, suggests that more general models are required to account for single-molecule measurements performed with high temporal resolution. Here, we consider one such generalization: a model where the diffusion coefficient can be an arbitrary function of the reaction coordinate. Assuming Brownian dynamics along this coordinate, we derive an exact expression for the coordinate-dependent diffusivity in terms of the splitting probability within an arbitrarily chosen interval and the mean transition path time between the interval boundaries. This formula can be used to estimate the effective diffusion coefficient along a reaction coordinate directly from single-molecule trajectories. PMID- 29195292 TI - Water liquid-vapor interface subjected to various electric fields: A molecular dynamics study. AB - Investigation of the effects of E-fields on the liquid-vapor interface is essential for the study of floating water bridge and wetting phenomena. The present study employs the molecular dynamics method to investigate the effects of parallel and perpendicular E-fields on the water liquid-vapor interface. For this purpose, density distribution, number of hydrogen bonds, molecular orientation, and surface tension are examined to gain a better understanding of the interface structure. Results indicate enhancements in parallel E-field decrease the interface width and number of hydrogen bonds, while the opposite holds true in the case of perpendicular E-fields. Moreover, perpendicular fields disturb the water structure at the interface. Given that water molecules tend to be parallel to the interface plane, it is observed that perpendicular E-fields fail to realign water molecules in the field direction while the parallel ones easily do so. It is also shown that surface tension rises with increasing strength of parallel E-fields, while it reduces in the case of perpendicular E-fields. Enhancement of surface tension in the parallel field direction demonstrates how the floating water bridge forms between the beakers. Finally, it is found that application of external E-fields to the liquid-vapor interface does not lead to uniform changes in surface tension and that the liquid-vapor interfacial tension term in Young's equation should be calculated near the triple-line of the droplet. This is attributed to the multi-directional nature of the droplet surface, indicating that no constant value can be assigned to a droplet's surface tension in the presence of large electric fields.

PMID- 29195294 TI - Correlation effects beyond coupled cluster singles and doubles approximation through Fock matrix dressing. AB - We present an accurate single reference coupled cluster theory in which the conventional Fock operator matrix is suitably dressed to simulate the effect of triple and higher excitations within a singles and doubles framework. The dressing thus invoked originates from a second-order perturbative approximation of a similarity transformed Hamiltonian and induces higher rank excitations through local renormalization of individual occupied and unoccupied orbital lines. Such a dressing is able to recover a significant amount of correlation effects beyond singles and doubles approximation, but only with an economic n5 additional cost. Due to the inclusion of higher rank excitations via the Fock matrix dressing, this method is a natural improvement over conventional coupled cluster theory with singles and doubles approximation, and this method would be demonstrated via applications on some challenging systems. This highly promising scheme has a conceptually simple structure which is also easily generalizable to a multi-reference coupled cluster scheme for treating strong degeneracy. We shall demonstrate that this method is a natural lowest order perturbative approximation to the recently developed iterative n-body excitation inclusive coupled cluster singles and doubles scheme [R. Maitra et al., J. Chem. Phys. 147, 074103 (2017)]. PMID- 29195295 TI - Methods to locate saddle points in complex landscapes. AB - We present a class of simple algorithms that allows us to find the reaction path in systems with a complex potential energy landscape. The approach does not need any knowledge on the product state and does not require the calculation of any second derivatives. The underlying idea is to use two nearby points in the configuration space to locate the path of the slowest ascent. By introducing a weak noise term, the algorithm is able to find even low-lying saddle points that are not directly reachable by means of the slowest ascent path. Since the algorithm only makes use of the value of the potential and its gradient, the computational effort to find saddle points is linear in the number of degrees of freedom if the potential is short-ranged. We test the performance of the algorithm for three potential energy landscapes. For the Muller-Brown surface, we find that the algorithm always finds the correct saddle point. For the modified Muller-Brown surface, which has a saddle point that is not reachable by means of the slowest ascent path, the algorithm is still able to find this saddle point with high probability. For the case of a three-dimensional Lennard-Jones cluster, the algorithm is able to find the lowest energy barrier with high probability, showing that the method is also efficient in landscapes with many dimensions.

AB - We solve the time-dependent Schrodinger equation describing a water molecule driven by a superposition of the extreme ultraviolet and IR pulses typical for a reconstruction of attosecond beating by interference of two-photon transitions experiment. This solution is obtained by a combination of the time-dependent coordinate scaling and the density functional theory with self-interaction correction. Results of this solution are used to determine the time delay in photoionization of the water and hydrogen molecules. PMID- 29195297 TI - Random number generator based on an integrated laser with on-chip optical feedback. AB - We discuss the design and testing of a laser integrated with a long on-chip optical feedback section. The device and feedback section have been fabricated on a generic photonic integration platform using only standard building blocks. We have been able to integrate a 10 cm feedback length on a footprint of 5.5 mm2. By controlling the amount of feedback, we achieve chaotic dynamics in the long cavity regime and show that the resulting dynamics is sufficiently complex in order to generate random bits based on the chaotic intensity fluctuation at a rate of 500 Mbits/s. PMID- 29195298 TI - New type of chimera and mutual synchronization of spatiotemporal structures in two coupled ensembles of nonlocally interacting chaotic maps. AB - We study numerically the dynamics of a network made of two coupled one dimensional ensembles of discrete-time systems. The first ensemble is represented by a ring of nonlocally coupled Henon maps and the second one by a ring of nonlocally coupled Lozi maps. We find that the network of coupled ensembles can realize all the spatio-temporal structures which are observed both in the Henon map ensemble and in the Lozi map ensemble while uncoupled. Moreover, we reveal a new type of spatiotemporal structure, a solitary state chimera, in the considered network. We also establish and describe the effect of mutual synchronization of various complex spatiotemporal patterns in the system of two coupled ensembles of Henon and Lozi maps. PMID- 29195299 TI - Noise activated bistable sensor based on chaotic system with output defined by temporal coding and firing rate. AB - Traditional bistable sensors use external bias signal to drive its response between states and their detection strategy is based on the output power spectral density or the residence time difference (RTD) in two sensor states. Recently, the noise activated nonlinear dynamic sensors driven only by noise based on RTD technique have been proposed. Here, we present experimental results of dc voltage measurements by noise-driven bistable sensor based on electronic Chua's circuit operating in a chaotic regime where two single scroll attractors coexist. The output of the sensor is quantified by the proportion of the time the sensor stays in one state to the total observation time and by the spike-count rate with spikes defined by crossings between attractors. The relationship between the stimuli and particular observable for different noise intensities is obtained, the usefulness of each coding scheme is discussed, and the optimal noise intensity for detection is indicated. It is shown that the obtained relationship is the same for any observation time when population coding is used. The optimal time window for both detection and the number of units in population coding is found. Our results may be useful for analyses and understanding of the neural activity and in designing bistable storage elements at length scales where thermal fluctuations drastically increase and the effect of noise must be taken into consideration. PMID- 29195300 TI - Pseudo-spatial coherence resonance in an excitable laser with long delayed feedback. AB - The effect of noise in an excitable semiconductor laser with feedback is studied in the framework of the spatio-temporal representation of long delayed systems. Propagation, noise-induced creation, and destruction of excitable pulses in the pseudo time are observed. The addition of a variable quantity of noise leads to the occurrence of a phenomenon that we term "pseudo-spatial coherence resonance." A phenomenological model well describes the system and allows for a comparison with the experimental observations. A simple Monte Carlo approach is also introduced and permits to explain the features observed in terms of the key dynamical ingredients of the physical system. PMID- 29195301 TI - Drifting cavity solitons and dissipative rogue waves induced by time-delayed feedback in Kerr optical frequency comb and in all fiber cavities. AB - Time-delayed feedback plays an important role in the dynamics of spatially extended systems. In this contribution, we consider the generic Lugiato-Lefever model with delay feedback that describes Kerr optical frequency comb in all fiber cavities. We show that the delay feedback strongly impacts the spatiotemporal dynamical behavior resulting from modulational instability by (i) reducing the threshold associated with modulational instability and by (ii) decreasing the critical frequency at the onset of this instability. We show that for moderate input intensities it is possible to generate drifting cavity solitons with an asymmetric radiation emitted from the soliton tails. Finally, we characterize the formation of rogue waves induced by the delay feedback. PMID- 29195302 TI - Transient behavior between multi-cell flow states in ferrofluidic Taylor-Couette flow. AB - We investigate transient behaviors induced by magnetic fields on the dynamics of the flow of a ferrofluid in the gap between two concentric, independently rotating cylinders. Without applying any magnetic fields, we uncover emergence of flow states constituted by a combination of a localized spiral state in the top and bottom of the annulus and different multi-cell flow states with toroidally closed vortices in the interior of the bulk. However, when a magnetic field is presented, we observe the transient behaviors between multi-cell states passing through two critical thresholds in a strength of an axial (transverse) magnetic field. Before the first critical threshold of a magnetic field strength, multi stable states with different number of cells could be observed. After the first critical threshold, we find the transient behavior between the three- and two cell flow states. For more strength of magnetic field or after the second critical threshold, we discover that multi-cell states are disappeared and a localized spiral state remains to be stimulated. The studied transient behavior could be understood by the investigation of various quantities including a modal kinetic energy, a mode amplitude of the radial velocity, wavenumber, angular momentum, and torque. In addition, the emergence of new flow states and the transient behavior between their states in ferrofluidic flows indicate that richer and potentially controllable dynamics through magnetic fields could be possible in ferrofluic flow. PMID- 29195303 TI - The influence of parametric and external noise in act-and-wait control with delayed feedback. AB - We apply several novel semi-analytic approaches for characterizing and calculating the effects of noise in a system with act-and-wait control. For concrete illustration, we apply these to a canonical balance model for an inverted pendulum to study the combined effect of delay and noise within the act and-wait setting. While the act-and-wait control facilitates strong stabilization through deadbeat control, a comparison of different models with continuous vs. discrete updating of the control strategy in the active period illustrates how delays combined with the imprecise application of the control can seriously degrade the performance. We give several novel analyses of a generalized act-and wait control strategy, allowing flexibility in the updating of the control strategy, in order to understand the sensitivities to delays and random fluctuations. In both the deterministic and stochastic settings, we give analytical and semi-analytical results that characterize and quantify the dynamics of the system. These results include the size and shape of stability regions, densities for the critical eigenvalues that capture the rate of reaching the desired stable equilibrium, and amplification factors for sustained fluctuations in the context of external noise. They also provide the dependence of these quantities on the length of the delay and the active period. In particular, we see that the combined influence of delay, parametric error, or external noise and on-off control can qualitatively change the dynamics, thus reducing the robustness of the control strategy. We also capture the dependence on how frequently the control is updated, allowing an interpolation between continuous and frequent updating. In addition to providing insights for these specific models, the methods we propose are generalizable to other settings with noise, delay, and on-off control, where analytical techniques are otherwise severely scarce. PMID- 29195304 TI - Role of dynamical injection locking and characteristic pulse events for low frequency fluctuations in semiconductor lasers. AB - We investigate the dynamics of semiconductor lasers subject to time-delayed optical feedback from the perspective of dynamical self-injection locking. Based on the Lang-Kobayashi model, we perform an analysis of the well-known Low Frequency Fluctuations (LFFs) in the frequency-intensity plane. Moreover, we investigate a recently found dynamical regime of fragmented LFFs by means of a locking-range analysis, spectral comparison and precursor pulse identification. We show that LFF dynamics can be explained by dynamical optical injection locking due to the delayed optical feedback. Moreover, the fragmented LFFs occur due to a re-injection locking induced by a particular optical pulse structure in the chaotic feedback dynamics. This is corroborated by experiments with a semiconductor laser experiencing delayed feedback from an optical fiber loop. The dynamical nature of the feedback injection results in an eventual loss, but also possible regaining, of the locking, explaining the recently observed phenomenon of fragmented LFFs. PMID- 29195305 TI - Opinion evolution in different social acquaintance networks. AB - Social acquaintance networks influenced by social culture and social policy have a great impact on public opinion evolution in daily life. Based on the differences between socio-culture and social policy, three different social acquaintance networks (kinship-priority acquaintance network, independence priority acquaintance network, and hybrid acquaintance network) incorporating heredity proportion ph and variation proportion pv are proposed in this paper. Numerical experiments are conducted to investigate network topology and different phenomena during opinion evolution, using the Deffuant model. We found that in kinship-priority acquaintance networks, similar to the Chinese traditional acquaintance networks, opinions always achieve fragmentation, resulting in the formation of multiple large clusters and many small clusters due to the fact that individuals believe more in their relatives and live in a relatively closed environment. In independence-priority acquaintance networks, similar to Western acquaintance networks, the results are similar to those in the kinship-priority acquaintance network. In hybrid acquaintance networks, similar to the Chinese modern acquaintance networks, only a few clusters are formed indicating that in modern China, opinions are more likely to reach consensus on a large scale. These results are similar to the opinion evolution phenomena in modern society, proving the rationality and applicability of network models combined with social culture and policy. We also found a threshold curve pv+2ph=2.05 in the results for the final opinion clusters and evolution time. Above the threshold curve, opinions could easily reach consensus. Based on the above experimental results, a culture policy-driven mechanism for the opinion dynamic is worth promoting in this paper, that is, opinion dynamics can be driven by different social cultures and policies through the influence of heredity and variation in interpersonal relationship networks. This finding is of great significance for predicting opinion evolution under different acquaintance networks and formulating reasonable policies based on cultural characteristics to guide public opinion. PMID- 29195306 TI - Exploring the route to measure synchronization in non-linearly coupled Hamiltonian systems. AB - Measure Synchronization is a general term used for weak synchronization in Hamiltonian systems. Route to measure synchronization in a system of two non linearly coupled one-dimensional oscillators, the potential of which is represented by the Pullen-Edmonds Potential is investigated on the basis of numerical computation. Transitions to measure synchronization and unsynchronization, both quasiperiodic and chaotic, are investigated and distinguished on the basis of the variation of average bare energies, average interaction energy, root-mean-square value of oscillations, phase difference, and frequencies with the coupling strength. A suitable order parameter to identify and characterize both quasiperiodic and chaotic measure synchronous states is sought, and drawbacks of the various order parameters, suggested previously, are discussed. PMID- 29195307 TI - Mean, covariance, and effective dimension of stochastic distributed delay dynamics. AB - Dynamical models are often required to incorporate both delays and noise. However, the inherently infinite-dimensional nature of delay equations makes formal solutions to stochastic delay differential equations (SDDEs) challenging. Here, we present an approach, similar in spirit to the analysis of functional differential equations, but based on finite-dimensional matrix operators. This results in a method for obtaining both transient and stationary solutions that is directly amenable to computation, and applicable to first order differential systems with either discrete or distributed delays. With fewer assumptions on the system's parameters than other current solution methods and no need to be near a bifurcation, we decompose the solution to a linear SDDE with arbitrary distributed delays into natural modes, in effect the eigenfunctions of the differential operator, and show that relatively few modes can suffice to approximate the probability density of solutions. Thus, we are led to conclude that noise makes these SDDEs effectively low dimensional, which opens the possibility of practical definitions of probability densities over their solution space.

AB - Type 2 diabetes mellitus (T2DM) has become prevalent pandemic disease in view of the modern life style. Both diabetic population and health expenses grow rapidly according to American Diabetes Association. Detecting the potential onset of T2DM is an essential focal point in the research of diabetes mellitus. The intravenous glucose tolerance test (IVGTT) is an effective protocol to determine the insulin sensitivity, glucose effectiveness, and pancreatic beta-cell functionality, through the analysis and parameter estimation of a proper differential equation model. Delay differential equations have been used to study the complex physiological phenomena including the glucose and insulin regulations. In this paper, we propose a novel approach to model the time delay in IVGTT modeling. This novel approach uses two parameters to simulate not only both discrete time delay and distributed time delay in the past interval, but also the time delay distributed in a past sub-interval. Normally, larger time delay, either a discrete or a distributed delay, will destabilize the system. However, we find that time delay over a sub-interval might not. We present analytically some basic model properties, which are desirable biologically and mathematically. We show that this relatively simple model provides good fit to fluctuating patient data sets and reveals some intriguing dynamics. Moreover, our numerical simulation results indicate that our model may remove the defect in well known Minimal Model, which often overestimates the glucose effectiveness index.

AB - With the recent exponential growth of applications using artificial intelligence (AI), the development of efficient and ultrafast brain-like (neuromorphic) systems is crucial for future information and communication technologies. While the implementation of AI systems using computer algorithms of neural networks is emerging rapidly, scientists are just taking the very first steps in the development of the hardware elements of an artificial brain, specifically neuromorphic microchips. In this review article, we present the current state of the art of neuromorphic photonic circuits based on solid-state optoelectronic oscillators formed by nanoscale double barrier quantum well resonant tunneling diodes. We address, both experimentally and theoretically, the key dynamic properties of recently developed artificial solid-state neuron microchips with delayed perturbations and describe their role in the study of neural activity and regenerative memory. This review covers our recent research work on excitable and delay dynamic characteristics of both single and autaptic (delayed) artificial neurons including all-or-none response, spike-based data encoding, storage, signal regeneration and signal healing. Furthermore, the neural responses of these neuromorphic microchips display all the signatures of extended spatio temporal localized structures (LSs) of light, which are reviewed here in detail. By taking advantage of the dissipative nature of LSs, we demonstrate potential applications in optical data reconfiguration and clock and timing at high-speeds and with short transients. The results reviewed in this article are a key enabler for the development of high-performance optoelectronic devices in future high speed brain-inspired optical memories and neuromorphic computing. PMID- 29195311 TI - Chimera states in multi-strain epidemic models with temporary immunity. AB - We investigate a time-delayed epidemic model for multi-strain diseases with temporary immunity. In the absence of cross-immunity between strains, dynamics of each individual strain exhibit emergence and annihilation of limit cycles due to a Hopf bifurcation of the endemic equilibrium, and a saddle-node bifurcation of limit cycles depending on the time delay associated with duration of temporary immunity. Effects of all-to-all and non-local coupling topologies are systematically investigated by means of numerical simulations, and they suggest that cross-immunity is able to induce a diverse range of complex dynamical behaviors and synchronization patterns, including discrete traveling waves, solitary states, and amplitude chimeras. Interestingly, chimera states are observed for narrower cross-immunity kernels, which can have profound implications for understanding the dynamics of multi-strain diseases. PMID- 29195312 TI - Introduction to Focus Issue: Time-delay dynamics. AB - The field of dynamical systems with time delay is an active research area that connects practically all scientific disciplines including mathematics, physics, engineering, biology, neuroscience, physiology, economics, and many others. This Focus Issue brings together contributions from both experimental and theoretical groups and emphasizes a large variety of applications. In particular, lasers and optoelectronic oscillators subject to time-delayed feedbacks have been explored by several authors for their specific dynamical output, but also because they are ideal test-beds for experimental studies of delay induced phenomena. Topics include the control of cavity solitons, as light spots in spatially extended systems, new devices for chaos communication or random number generation, higher order locking phenomena between delay and laser oscillation period, and systematic bifurcation studies of mode-locked laser systems. Moreover, two original theoretical approaches are explored for the so-called Low Frequency Fluctuations, a particular chaotical regime in laser output which has attracted a lot of interest for more than 30 years. Current hot problems such as the synchronization properties of networks of delay-coupled units, novel stabilization techniques, and the large delay limit of a delay differential equation are also addressed in this special issue. In addition, analytical and numerical tools for bifurcation problems with or without noise and two reviews on concrete questions are proposed. The first review deals with the rich dynamics of simple delay climate models for El Nino Southern Oscillations, and the second review concentrates on neuromorphic photonic circuits where optical elements are used to emulate spiking neurons. Finally, two interesting biological problems are considered in this Focus Issue, namely, multi-strain epidemic models and the interaction of glucose and insulin for more effective treatment.

AB - We investigate the dynamic mechanisms for low frequency fluctuations in semiconductor lasers subjected to delayed optical feedback, using the Lang Kobayashi model. This system of delay differential equations displays pronounced envelope dynamics, ranging from erratic, so called low frequency fluctuations to regular pulse packages, if the time scales of fast oscillations and envelope dynamics are well separated. We investigate the parameter regions where low frequency fluctuations occur and compute their Lyapunov spectra. Using the geometric singular perturbation theory, we study this intermittent chaotic behavior and characterize these solutions as bursting slow-fast oscillations.

AB - Using the model of a FitzHugh-Nagumo system in the excitable regime, we investigate the influence of time-delayed feedback on noise-induced chimera states in a network with nonlocal coupling, i.e., coherence resonance chimeras. It is shown that time-delayed feedback allows for the control of the range of parameter values where these chimera states occur. Moreover, for the feedback delay close to the intrinsic period of the system, we find a novel regime which we call period-two coherence resonance chimera. PMID- 29195315 TI - The impact of propagation and processing delays on amplitude and oscillation deaths in the presence of symmetry-breaking coupling. AB - We numerically investigate the impacts of both propagation and processing delays on the emergences of amplitude death (AD) and oscillation death (OD) in one system of two Stuart-Landau oscillators with symmetry-breaking coupling. In either the absence of or the presence of propagation delay, the processing delay destabilizes both AD and OD by revoking the stability of the stable homogenous and inhomogenous steady states. In the AD to OD transition, the processing delay destabilizes first OD from large values of coupling strength until its stable regime completely disappears and then AD from both the upper and lower bounds of the stable coupling interval. Our numerical study sheds new insight lights on the understanding of nontrivial effects of time delays on dynamic activity of coupled nonlinear systems. PMID- 29195316 TI - Computing aggregate properties of preimages for 2D cellular automata. AB - Computing properties of the set of precursors of a given configuration is a common problem underlying many important questions about cellular automata. Unfortunately, such computations quickly become intractable in dimension greater than one. This paper presents an algorithm-incremental aggregation-that can compute aggregate properties of the set of precursors exponentially faster than naive approaches. The incremental aggregation algorithm is demonstrated on two problems from the two-dimensional binary Game of Life cellular automaton: precursor count distributions and higher-order mean field theory coefficients. In both cases, incremental aggregation allows us to obtain new results that were previously beyond reach. PMID- 29195317 TI - Climate models with delay differential equations. AB - A fundamental challenge in mathematical modelling is to find a model that embodies the essential underlying physics of a system, while at the same time being simple enough to allow for mathematical analysis. Delay differential equations (DDEs) can often assist in this goal because, in some cases, only the delayed effects of complex processes need to be described and not the processes themselves. This is true for some climate systems, whose dynamics are driven in part by delayed feedback loops associated with transport times of mass or energy from one location of the globe to another. The infinite-dimensional nature of DDEs allows them to be sufficiently complex to reproduce realistic dynamics accurately with a small number of variables and parameters. In this paper, we review how DDEs have been used to model climate systems at a conceptual level. Most studies of DDE climate models have focused on gaining insights into either the global energy balance or the fundamental workings of the El Nino Southern Oscillation (ENSO) system. For example, studies of DDEs have led to proposed mechanisms for the interannual oscillations in sea-surface temperature that is characteristic of ENSO, the irregular behaviour that makes ENSO difficult to forecast and the tendency of El Nino events to occur near Christmas. We also discuss the tools used to analyse such DDE models. In particular, the recent development of continuation software for DDEs makes it possible to explore large regions of parameter space in an efficient manner in order to provide a "global picture" of the possible dynamics. We also point out some directions for future research, including the incorporation of non-constant delays, which we believe could improve the descriptive power of DDE climate models.

AB - Semiconductor lasers with time-delayed optical feedback display a wide range of dynamical regimes, which have found various practical applications. They also provide excellent testbeds for data analysis tools for characterizing complex signals. Recently, several of us have analyzed experimental intensity time-traces and quantitatively identified the onset of different dynamical regimes, as the laser current increases. Specifically, we identified the onset of low-frequency fluctuations (LFFs), where the laser intensity displays abrupt dropouts, and the onset of coherence collapse (CC), where the intensity fluctuations are highly irregular. Here we map these regimes when both, the laser current and the feedback strength vary. We show that the shape of the distribution of intensity fluctuations (characterized by the standard deviation, the skewness, and the kurtosis) allows to distinguish among noise, LFFs and CC, and to quantitatively determine (in spite of the gradual nature of the transitions) the boundaries of the three regimes. Ordinal analysis of the inter-dropout time intervals consistently identifies the three regimes occurring in the same parameter regions as the analysis of the intensity distribution. Simulations of the well-known time delayed Lang-Kobayashi model are in good qualitative agreement with the observations. PMID- 29195319 TI - Controlling Mackey-Glass chaos. AB - The Mackey-Glass equation is the representative example of delay induced chaotic behavior. Here, we propose various control mechanisms so that otherwise erratic solutions are forced to converge to the positive equilibrium or to a periodic orbit oscillating around that equilibrium. We take advantage of some recent results of the delay differential literature, when a sufficiently large domain of the phase space has been shown to be attractive and invariant, where the system is governed by monotone delayed feedback and chaos is not possible due to some Poincare-Bendixson type results. We systematically investigate what control mechanisms are suitable to drive the system into such a situation and prove that constant perturbation, proportional feedback control, Pyragas control, and state dependent delay control can all be efficient to control Mackey-Glass chaos with properly chosen control parameters. PMID- 29195320 TI - Symmetry, Hopf bifurcation, and the emergence of cluster solutions in time delayed neural networks. AB - We consider the networks of N identical oscillators with time delayed, global circulant coupling, modeled by a system of delay differential equations with ZN symmetry. We first study the existence of Hopf bifurcations induced by the coupling time delay and then use symmetric Hopf bifurcation theory to determine how these bifurcations lead to different patterns of symmetric cluster oscillations. We apply our results to a case study: a network of FitzHugh-Nagumo neurons with diffusive coupling. For this model, we derive the asymptotic stability, global asymptotic stability, absolute instability, and stability switches of the equilibrium point in the plane of coupling time delay (tau) and excitability parameter (a). We investigate the patterns of cluster oscillations induced by the time delay and determine the direction and stability of the bifurcating periodic orbits by employing the multiple timescales method and normal form theory. We find that in the region where stability switching occurs, the dynamics of the system can be switched from the equilibrium point to any symmetric cluster oscillation, and back to equilibrium point as the time delay is increased. PMID- 29195321 TI - Anticipated and zero-lag synchronization in motifs of delay-coupled systems. AB - Anticipated and zero-lag synchronization have been observed in different scientific fields. In the brain, they might play a fundamental role in information processing, temporal coding and spatial attention. Recent numerical work on anticipated and zero-lag synchronization studied the role of delays. However, an analytical understanding of the conditions for these phenomena remains elusive. In this paper, we study both phenomena in systems with small delays. By performing a phase reduction and studying phase locked solutions, we uncover the functional relation between the delay, excitation and inhibition for the onset of anticipated synchronization in a sender-receiver-interneuron motif. In the case of zero-lag synchronization in a chain motif, we determine the stability conditions. These analytical solutions provide an excellent prediction of the phase-locked regimes of Hodgkin-Huxley models and Roessler oscillators. PMID- 29195322 TI - Reduced alpha-stable dynamics for multiple time scale systems forced with correlated additive and multiplicative Gaussian white noise. AB - Stochastic averaging problems with Gaussian forcing have been the subject of numerous studies, but far less attention has been paid to problems with infinite variance stochastic forcing, such as an alpha-stable noise process. It has been shown that simple linear systems driven by correlated additive and multiplicative (CAM) Gaussian noise, which emerge in the context of reduced atmosphere and ocean dynamics, have infinite variance in certain parameter regimes. In this study, we consider the stochastic averaging of systems where a linear CAM noise process in the infinite variance parameter regime drives a comparatively slow process. We use (semi)-analytical approximations combined with numerical illustrations to compare the averaged process to one that is forced by a white alpha-stable process, demonstrating consistent properties in the case of large time-scale separation. We identify the conditions required for the fast linear CAM process to have such an influence in driving a slower process and then derive an (effectively) equivalent fast, infinite-variance process for which an existing stochastic averaging approximation is readily applied. The results are illustrated using numerical simulations of a set of example systems. PMID- 29195323 TI - Small-world networks exhibit pronounced intermittent synchronization. AB - We report the phenomenon of temporally intermittently synchronized and desynchronized dynamics in Watts-Strogatz networks of chaotic Rossler oscillators. We consider topologies for which the master stability function (MSF) predicts stable synchronized behaviour, as the rewiring probability (p) is tuned from 0 to 1. MSF essentially utilizes the largest non-zero Lyapunov exponent transversal to the synchronization manifold in making stability considerations, thereby ignoring the other Lyapunov exponents. However, for an N-node networked dynamical system, we observe that the difference in its Lyapunov spectra (corresponding to the N - 1 directions transversal to the synchronization manifold) is crucial and serves as an indicator of the presence of intermittently synchronized behaviour. In addition to the linear stability-based (MSF) analysis, we further provide global stability estimate in terms of the fraction of state space volume shared by the intermittently synchronized state, as p is varied from 0 to 1. This fraction becomes appreciably large in the small-world regime, which is surprising, since this limit has been otherwise considered optimal for synchronized dynamics. Finally, we characterize the nature of the observed intermittency and its dominance in state-space as network rewiring probability (p) is varied. PMID- 29195324 TI - Using periodic orbits to compute chaotic transport rates between resonance zones. AB - Transport properties of chaotic systems are computable from data extracted from periodic orbits. Given a sufficient number of periodic orbits, the escape rate can be computed using the spectral determinant, a function that incorporates the eigenvalues and periods of periodic orbits. The escape rate computed from periodic orbits converges to the true value as more and more periodic orbits are included. Escape from a given region of phase space can be computed by considering only periodic orbits that lie within the region. An accurate symbolic dynamics along with a corresponding partitioning of phase space is useful for systematically obtaining all periodic orbits up to a given period, to ensure that no important periodic orbits are missing in the computation. Homotopic lobe dynamics (HLD) is an automated technique for computing accurate partitions and symbolic dynamics for maps using the topological forcing of intersections of stable and unstable manifolds of a few periodic anchor orbits. In this study, we apply the HLD technique to compute symbolic dynamics and periodic orbits, which are then used to find escape rates from different regions of phase space for the Henon map. We focus on computing escape rates in parameter ranges spanning hyperbolic plateaus, which are parameter intervals where the dynamics is hyperbolic and the symbolic dynamics does not change. After the periodic orbits are computed for a single parameter value within a hyperbolic plateau, periodic orbit continuation is used to compute periodic orbits over an interval that spans the hyperbolic plateau. The escape rates computed from a few thousand periodic orbits agree with escape rates computed from Monte Carlo simulations requiring hundreds of billions of orbits. PMID- 29195325 TI - Stochastic resonance in a delayed triple-well potential driven by correlated noises. AB - In this paper, we investigate stochastic resonance (SR) in a delayed triple-well potential subject to correlated noises and a harmonic signal. The stationary probability density, together with the response amplitude of the system, is obtained by using the small time delay approximation. It is found that the time delay, noise intensities, and the cross-correlation between noises can induce the occurrence of the transition. Moreover, the appropriate choice of noise intensities and time delay can improve the output of the system, enhance the SR effect, and lead to the phenomenon of noise enhanced stability. Especially, the stochastic multi-resonance phenomenon is observed when the multiplicative and additive noises are correlated. Finally, the theoretical results are well verified through numerical simulations. PMID- 29195326 TI - Multipulse dynamics of a passively mode-locked semiconductor laser with delayed optical feedback. AB - Passively mode-locked semiconductor lasers are compact, inexpensive sources of short light pulses of high repetition rates. In this work, we investigate the dynamics and bifurcations arising in such a device under the influence of time delayed optical feedback. This laser system is modelled by a system of delay differential equations, which includes delay terms associated with the laser cavity and feedback loop. We make use of specialised path continuation software for delay differential equations to analyse the regime of short feedback delays. Specifically, we consider how the dynamics and bifurcations depend on the pump current of the laser, the feedback strength, and the feedback delay time. We show that an important role is played by resonances between the mode-locking frequencies and the feedback delay time. We find feedback-induced harmonic mode locking and show that a mismatch between the fundamental frequency of the laser and that of the feedback cavity can lead to multi-pulse or quasiperiodic dynamics. The quasiperiodic dynamics exhibit a slow modulation, on the time scale of the gain recovery rate, which results from a beating with the frequency introduced in the associated torus bifurcations and leads to gain competition between multiple pulse trains within the laser cavity. Our results also have implications for the case of large feedback delay times, where a complete bifurcation analysis is not practical. Namely, for increasing delay, there is an ever-increasing degree of multistability between mode-locked solutions due to the frequency pulling effect. PMID- 29195327 TI - Stochastic modelling of non-stationary financial assets. AB - We model non-stationary volume-price distributions with a log-normal distribution and collect the time series of its two parameters. The time series of the two parameters are shown to be stationary and Markov-like and consequently can be modelled with Langevin equations, which are derived directly from their series of values. Having the evolution equations of the log-normal parameters, we reconstruct the statistics of the first moments of volume-price distributions which fit well the empirical data. Finally, the proposed framework is general enough to study other non-stationary stochastic variables in other research fields, namely, biology, medicine, and geology. PMID- 29195328 TI - Delayed feedback control of self-mobile cavity solitons in a wide-aperture laser with a saturable absorber. AB - We investigate the spatiotemporal dynamics of cavity solitons in a broad area vertical-cavity surface-emitting laser with saturable absorption subjected to time-delayed optical feedback. Using a combination of analytical, numerical, and path continuation methods, we analyze the bifurcation structure of stationary and moving cavity solitons and identify two different types of traveling localized solutions, corresponding to slow and fast motion. We show that the delay impacts both stationary and moving solutions either causing drifting and wiggling dynamics of initially stationary cavity solitons or leading to stabilization of intrinsically moving solutions. Finally, we demonstrate that the fast cavity solitons can be associated with a lateral mode-locking regime in a broad-area laser with a single longitudinal mode. PMID- 29195329 TI - Delay induced high order locking effects in semiconductor lasers. AB - Multiple time scales appear in many nonlinear dynamical systems. Semiconductor lasers, in particular, provide a fertile testing ground for multiple time scale dynamics. For solitary semiconductor lasers, the two fundamental time scales are the cavity repetition rate and the relaxation oscillation frequency which is a characteristic of the field-matter interaction in the cavity. Typically, these two time scales are of very different orders, and mutual resonances do not occur. Optical feedback endows the system with a third time scale: the external cavity repetition rate. This is typically much longer than the device cavity repetition rate and suggests the possibility of resonances with the relaxation oscillations. We show that for lasers with highly damped relaxation oscillations, such resonances can be obtained and lead to spontaneous mode-locking. Two different laser types--a quantum dot based device and a quantum well based device-are analysed experimentally yielding qualitatively identical dynamics. A rate equation model is also employed showing an excellent agreement with the experimental results. PMID- 29195330 TI - Nonlinear dynamics of an elliptic vortex embedded in an oscillatory shear flow. AB - The nonlinear dynamics of an elliptic vortex subjected to a time-periodic linear external shear flow is studied numerically. Making use of the ideas from the theory of nonlinear resonance overlaps, the study focuses on the appearance of chaotic regimes in the ellipse dynamics. When the superimposed flow is stationary, two general types of the steady-state phase portrait are considered: one that features a homoclinic separatrix delineating bounded and unbounded phase trajectories and one without a separatrix (all the phase trajectories are bounded in a periodic domain). When the external flow is time-periodic, the ensuing nonlinear dynamics differs significantly in both cases. For the case with a separatrix and two distinct types of phase trajectories: bounded and unbounded, the effect of the most influential nonlinear resonance with the winding number of 1:1 is analyzed in detail. Namely, the process of occupying the central stability region associated with the steady-state elliptic critical point by the stability region associated with the nonlinear resonance of 1:1 as the perturbation frequency gradually varies is investigated. A stark increase in the persistence of the central regular dynamics region against perturbation when the resonance of 1:1 associated stability region occupies the region associated with the steady state elliptic critical point is observed. An analogous persistence of the regular motion occurs for higher perturbation frequencies when the corresponding stability islands reach the central stability region associated with the steady state elliptic point. An analysis for the case with the resonance of 1:2 is presented. For the second case with only bounded phase trajectories and, therefore, no separatrix, the appearance of much bigger stability islands associated with nonlinear resonances compared with the case with a separatrix is reported. PMID- 29195331 TI - Solitons of the coupled Schrodinger-Korteweg-de Vries system with arbitrary strengths of the nonlinearity and dispersion. AB - New two-component soliton solutions of the coupled high-frequency (HF)-low frequency (LF) system, based on Schrodinger-Korteweg-de Vries (KdV) system with the Zakharov's coupling, are obtained for arbitrary relative strengths of the nonlinearity and dispersion in the LF component. The complex HF field is governed by the linear Schrodinger equation with a potential generated by the real LF component, which, in turn, is governed by the KdV equation including the ponderomotive coupling term, representing the feedback of the HF field onto the LF component. First, we study the evolution of pulse-shaped pulses by means of direct simulations. In the case when the dispersion of the LF component is weak in comparison to its nonlinearity, the input gives rise to several solitons in which the HF component is much broader than its LF counterpart. In the opposite case, the system creates a single soliton with approximately equal widths of both components. Collisions between stable solitons are studied too, with a conclusion that the collisions are inelastic, with a greater soliton getting still stronger, and the smaller one suffering further attenuation. Robust intrinsic modes are excited in the colliding solitons. A new family of approximate analytical two component soliton solutions with two free parameters is found for an arbitrary relative strength of the nonlinearity and dispersion of the LF component, assuming weak feedback of the HF field onto the LF component. Further, a one parameter (non-generic) family of exact bright-soliton solutions, with mutually proportional HF and LF components, is produced too. Intrinsic dynamics of the two component solitons, induced by a shift of their HF component against the LF one, is also studied, by means of numerical simulations, demonstrating excitation of a robust intrinsic mode. In addition to the above-mentioned results for LF dominated two-component solitons, which always run in one (positive) velocities, we produce HF-dominated soliton complexes, which travel in the opposite (negative) direction. They are obtained in a numerical form and by means of a quasi-adiabatic analytical approximation. The solutions with positive and negative velocities correspond, respectively, to super- and subsonic Davydov Scott solitons. PMID- 29195332 TI - Models of spin-orbit-coupled oligomers. AB - We address the stability and dynamics of eigenmodes in linearly shaped strings (dimers, trimers, tetramers, and pentamers) built of droplets in a binary Bose Einstein condensate (BEC). The binary BEC is composed of atoms in two pseudo-spin states with attractive interactions, dressed by properly arranged laser fields, which induce the (pseudo-) spin-orbit (SO) coupling. We demonstrate that the SO coupling terms help to create eigenmodes of particular types in the strings. Dimer, trimer, and pentamer eigenmodes of the linear system, which correspond to the zero eigenvalue (EV, alias chemical potential) extend into the nonlinear ones, keeping an exact analytical form, while tetramers do not admit such a continuation, because the respective spectrum does not contain a zero EV. Stability areas of these modes shrink with the increasing nonlinearity. Besides these modes, other types of nonlinear states, which are produced by the continuation of their linear counterparts corresponding to some nonzero EVs, are found in a numerical form (including ones for the tetramer system). They are stable in nearly entire existence regions in trimer and pentamer systems, but only in a very small area for the tetramers. Similar results are also obtained, but not displayed in detail, for hexa- and septamers. PMID- 29195334 TI - Local bifurcations in differential equations with state-dependent delay. AB - A common task when analysing dynamical systems is the determination of normal forms near local bifurcations of equilibria. As most of these normal forms have been classified and analysed, finding which particular class of normal form one encounters in a numerical bifurcation study guides follow-up computations. This paper builds on normal form algorithms for equilibria of delay differential equations with constant delay that were developed and implemented in DDE-Biftool recently. We show how one can extend these methods to delay-differential equations with state-dependent delay (sd-DDEs). Since higher degrees of regularity of local center manifolds are still open for sd-DDEs, we give an independent (still only partial) argument which phenomena from the truncated normal must persist in the full sd-DDE. In particular, we show that all invariant manifolds with a sufficient degree of normal hyperbolicity predicted by the normal form exist also in the full sd-DDE. PMID- 29195333 TI - Synchronization stability and pattern selection in a memristive neuronal network. AB - Spatial pattern formation and selection depend on the intrinsic self-organization and cooperation between nodes in spatiotemporal systems. Based on a memory neuron model, a regular network with electromagnetic induction is proposed to investigate the synchronization and pattern selection. In our model, the memristor is used to bridge the coupling between the magnetic flux and the membrane potential, and the induction current results from the time-varying electromagnetic field contributed by the exchange of ion currents and the distribution of charged ions. The statistical factor of synchronization predicts the transition of synchronization and pattern stability. The bifurcation analysis of the sampled time series for the membrane potential reveals the mode transition in electrical activity and pattern selection. A formation mechanism is outlined to account for the emergence of target waves. Although an external stimulus is imposed on each neuron uniformly, the diversity in the magnetic flux and the induction current leads to emergence of target waves in the studied network. PMID- 29195335 TI - Mapping of external cavity modes for a laser diode subject to phase-conjugate feedback. AB - We numerically investigate the dynamics of a semiconductor laser subject to phase conjugate optical feedback. We explore the effects of the laser model and feedback parameters for the generation of time-periodic oscillations of the output power at harmonics of the external cavity frequency, i.e., dynamical solutions that have been named external cavity modes. We point out that both the experimentally tunable and other parameters have an influence on the frequency of such dynamics. Since the delay has to exist, it is not the relevant parameter as we show that the feedback rate fixes the frequency of the periodic self pulsations. The interaction length of the crystal and the ratio between carrier and photon lifetimes tend to filter out high frequencies as they increase. Finally, the linewidth enhancement factor unlocks high frequencies as it increases. We conclude by providing a situation which leads to periodic solutions with higher frequencies using a set of realistic values of parameters. PMID- 29195336 TI - Control of electrical turbulence by periodic excitation of cardiac tissue. AB - Electrical turbulence in cardiac tissue is associated with arrhythmias such as life-threatening ventricular fibrillation. Recent experimental studies have shown that a sequence of low-energy electrical far-field pulses is able to terminate fibrillation more gently than a single high-energy pulse which causes severe side effects. During this low-energy antifibrillation pacing (LEAP), only tissue near sufficiently large conduction heterogeneities, such as large coronary arteries, is activated. In order to optimize LEAP, we performed extensive simulations of cardiac tissue perforated by blood vessels, employing two alternative cellular models that exhibit electrical turbulence at a similar length scale. Moreover, the scale of blood vessels in our two-dimensional simulations was chosen such that the threshold for single pulse defibrillation matches experimental values. For each of the 100 initial conditions, we tested different electrical field strengths, pulse shapes, numbers of pulses, and periods between the pulses. LEAP is successful for both models, albeit with substantial differences. One model exhibits a spectrum of chaotic activity featuring a narrow peak around a dominant frequency. In this case, the optimal period between low-energy pulses matches this frequency and LEAP greatly reduces the required energy for successful defibrillation. For pulses with larger energies, the system is perturbed such that underdrive pacing becomes advantageous. The spectrum of the second model features a broader peak, resulting in a less pronounced optimal pacing period and a decreased energy reduction. In both cases, pacing with five or six pulses which are separated by the dominant period maximizes the energy reduction. PMID- 29195337 TI - Multi-Gbit/s optical phase chaos communications using a time-delayed optoelectronic oscillator with a three-wave interferometer nonlinearity. AB - We propose a chaos communication scheme based on a chaotic optical phase carrier generated with an optoelectronic oscillator with nonlinear time-delay feedback. The system includes a dedicated non-local nonlinearity, which is a customized three-wave imbalanced interferometer. This particular feature increases the complexity of the chaotic waveform and thus the security of the transmitted information, as these interferometers are characterized by four independent parameters which are part of the secret key for the chaos encryption scheme. We first analyze the route to chaos in the system, and evidence a sequence of period doubling bifurcations from the steady-state to fully developed chaos. Then, in the chaotic regime, we study the synchronization between the emitter and the receiver, and achieve chaotic carrier cancellation with a signal-to-noise ratio up to 20 dB. We finally demonstrate error-free chaos communications at a data rate of 3 Gbit/s. PMID- 29195338 TI - Interactions and collisions of topological solitons in a semiconductor laser with optical injection and feedback. AB - We present experimental and numerical results about dynamical interactions of topological solitons in a semiconductor laser with coherent injection and feedback. We show different kind of interactions such as repulsion, annihilation, or formation of soliton bound states, depending on laser parameters. Collisions between single structures and bound states conserve momentum and charge. PMID- 29195339 TI - Quantization improves stabilization of dynamical systems with delayed feedback. AB - We show that an unstable scalar dynamical system with time-delayed feedback can be stabilized by quantizing the feedback. The discrete time model corresponds to a previously unrecognized case of the microchaotic map in which the fixed point is both locally and globally repelling. In the continuous-time model, stabilization by quantization is possible when the fixed point in the absence of feedback is an unstable node, and in the presence of feedback, it is an unstable focus (spiral). The results are illustrated with numerical simulation of the unstable Hayes equation. The solutions of the quantized Hayes equation take the form of oscillations in which the amplitude is a function of the size of the quantization step. If the quantization step is sufficiently small, the amplitude of the oscillations can be small enough to practically approximate the dynamics around a stable fixed point. PMID- 29195340 TI - Note: Wide-operating-range control for thermoelectric coolers. AB - A new algorithm for controlling the temperature of a thermoelectric cooler is proposed. Unlike a classic proportional-integral-derivative (PID) control, which computes the bias voltage from the temperature error, the proposed algorithm exploits the linear relation that exists between the cold side's temperature and the amount of heat that is removed per unit time. Since this control is based on an existing linear relation, it is insensitive to changes in the operating point that are instead crucial in classic PID control of a non-linear system. PMID- 29195341 TI - The effect of laser wavelength on the delay time of laser triggered vacuum switch. AB - The study on the influence of laser wavelength on the initial plasma properties of laser-triggered vacuum switch (LTVS) is not only beneficial to understanding the trigger mechanism but also to optimizing its design for miniaturization and generalization. In this paper, the one-dimensional heat conduction model of the target was developed and then the effect of laser wavelength on the depth of laser ablation and the quantity of initial plasma were investigated experimentally and theoretically with the laser absorption rate. The theoretical analysis was in good agreement with experimental measurement of the delay time of the LTVS. It is clear that the shorter the wavelength, the shorter the delay time will be after the LTVS is triggered. PMID- 29195342 TI - Grasping force hysteresis compensation of a piezoelectric-actuated wire clamp with a modified inverse Prandtl-Ishlinskii model. AB - This paper presents the grasping force hysteresis compensation of a piezoelectric actuated wire clamp with a modified hysteresis model. Considering dynamic characteristics of the wire clamp, a modified inverse Prandtl-Ishlinskii (MIPI) hysteresis model is developed to improve the hysteresis modeling accuracy. The proposed MIPI model is composed of a P-I model and a dynamic model which are connected in parallel. The proposed hysteresis model has the advantage of high modeling accuracy with a concise identification process, which means the step by step identification is not needed here. Experiments on grasping force hysteresis compensation with a feedforward controller are carried out based on the developed MIPI model. The grasping force error in steady state lies in +/-8.17 mN, while the maximum percentage and root mean square percentage of the grasping force error are 2.93% and 0.92%, respectively. The results show that the proposed hysteresis model is efficient and the wire clamp exhibits good performance with the feedforward controller. Therefore high frequency grasping operations can be realized based on the proposed MIPI hysteresis model. PMID- 29195343 TI - In situ ultraviolet shock radiance measurements using GaN-on-sapphire photodetectors. AB - Gallium nitride (GaN)-on-sapphire photodetectors are used to measure the ultraviolet (UV) radiance behind a shock wave in support of atmospheric entry sensing technologies. DC spectral response characterization of the GaN-based photodetectors shows a peak response around 365 nm with an UV/visible rejection of an order of magnitude. To conduct in situ measurements of UV shock-layer radiation, the GaN-based photodetectors were installed, without protective packaging, in the test section of a shock tube. The measured UV radiation, in terms of incident optical power on the photodetectors, is in excellent agreement with average UV radiation measured by the shock tube facility spectrometers. Furthermore, the device response after being subjected to the shock wave is unaltered, suggesting that the GaN-based material platform is suitable for implementation in aerospace and other harsh environment sensing applications. PMID- 29195344 TI - True randomness from an incoherent source. AB - Quantum random number generators (QRNGs) harness the intrinsic randomness in measurement processes: the measurement outputs are truly random, given the input state is a superposition of the eigenstates of the measurement operators. In the case of trusted devices, true randomness could be generated from a mixed state rho so long as the system entangled with rho is well protected. We propose a random number generation scheme based on measuring the quadrature fluctuations of a single mode thermal state using an optical homodyne detector. By mixing the output of a broadband amplified spontaneous emission (ASE) source with a single mode local oscillator (LO) at a beam splitter and performing differential photo detection, we can selectively detect the quadrature fluctuation of a single mode output of the ASE source, thanks to the filtering function of the LO. Experimentally, a quadrature variance about three orders of magnitude larger than the vacuum noise has been observed, suggesting this scheme can tolerate much higher detector noise in comparison with QRNGs based on measuring the vacuum noise. The high quality of this entropy source is evidenced by the small correlation coefficients of the acquired data. A Toeplitz-hashing extractor is applied to generate unbiased random bits from the Gaussian distributed raw data, achieving an efficiency of 5.12 bits per sample. The output of the Toeplitz extractor successfully passes all the NIST statistical tests for random numbers. PMID- 29195345 TI - Application of surface coil in nuclear magnetic resonance studies of physical properties of quasi-2D materials. AB - We conduct a comprehensive set of tests of performance of surface coils used for nuclear magnetic resonance (NMR) study of quasi-2-dimensional samples. We report 115In and 31P NMR measurements on InP, semi-conducting thin substrate samples. Surface coils of both zig-zag meander-line and concentric spiral geometries were used. We compare reception sensitivity and signal-to-noise ratio of the NMR signal obtained by using surface-type coils to that obtained by standard solenoid type coils. As expected, we find that surface-type coils provide better sensitivity for NMR study of thin film samples. Moreover, we compare the reception sensitivity of different types of the surface coils. We identify the optimal geometry of the surface coils for a given application and/or direction of the applied magnetic field. PMID- 29195346 TI - Experimental setup for the growth of solid crystals of inert gases for particle detection. AB - Low energy threshold detectors are necessary in many frontier fields of the experimental physics. In this work, we present a novel detection approach based on pure or doped matrices of inert gases solidified at cryogenic temperatures. The small energy release of the incident particle can be transferred directly (in pure crystals) or through a laser-driven ionization (in doped materials) to the electrons of the medium that are then converted into free electrons. The charge collection process of the electrons that consists in their drift within the crystal and their extraction through the solid-vacuum interface gives rise to an electric signal that we exploit for preliminary tests of charge collection and crystal quality. Such tests are carried out in different matrices of neon and methane using an UV-assisted apparatus for electron injection in crystals. PMID- 29195347 TI - Technique for insulated and non-insulated metal liner X-pinch radiography on a 1 MA pulsed power machine. AB - Broadband, high resolution X-pinch radiography has been demonstrated as a method to view the instability induced small scale structure that develops in near solid density regions of both insulated and non-insulated cylindrical metallic liners. In experiments carried out on a 1-1.2 MA 100-200 ns rise time pulsed power generator, MUm scale features were imaged in initially 16 MUm thick Al foil cylindrical liners. Better resolution and contrast were obtained using an X-ray sensitive film than with image plate detectors because of the properties of the X pinch X-ray source. We also discuss configuration variations that were made to the simple cylindrical liner geometry that appeared to maintain validity of the small-scale structure measurements while improving measurement quality. PMID- 29195348 TI - Simultaneous measurement of temperature, stress, and electric field in GaN HEMTs with micro-Raman spectroscopy. AB - As semiconductor devices based on silicon reach their intrinsic material limits, compound semiconductors, such as gallium nitride (GaN), are gaining increasing interest for high performance, solid-state transistor applications. Unfortunately, higher voltage, current, and/or power levels in GaN high electron mobility transistors (HEMTs) often result in elevated device temperatures, degraded performance, and shorter lifetimes. Although micro-Raman spectroscopy has become one of the most popular techniques for measuring localized temperature rise in GaN HEMTs for reliability assessment, decoupling the effects of temperature, mechanical stress, and electric field on the optical phonon frequencies measured by micro-Raman spectroscopy is challenging. In this work, we demonstrate the simultaneous measurement of temperature rise, inverse piezoelectric stress, thermoelastic stress, and vertical electric field via micro Raman spectroscopy from the shifts of the E2 (high), A1 longitudinal optical (LO), and E2 (low) optical phonon frequencies in wurtzite GaN. We also validate experimentally that the pinched OFF state as the unpowered reference accurately measures the temperature rise by removing the effect of the vertical electric field on the Raman spectrum and that the vertical electric field is approximately the same whether the channel is open or closed. Our experimental results are in good quantitative agreement with a 3D electro-thermo-mechanical model of the HEMT we tested and indicate that the GaN buffer acts as a semi-insulating, p-type material due to the presence of deep acceptors in the lower half of the bandgap. This implementation of micro-Raman spectroscopy offers an exciting opportunity to simultaneously probe thermal, mechanical, and electrical phenomena in semiconductor devices under bias, providing unique insight into the complex physics that describes device behavior and reliability. Although GaN HEMTs have been specifically used in this study to demonstrate its viability, this technique is applicable to any solid-state material with a suitable Raman response and will likely enable new measurement capabilities in a wide variety of scientific and engineering applications. PMID- 29195349 TI - Comparison of cryogenic low-pass filters. AB - Low-temperature electronic transport measurements with high energy resolution require both effective low-pass filtering of high-frequency input noise and an optimized thermalization of the electronic system of the experiment. In recent years, elaborate filter designs have been developed for cryogenic low-level measurements, driven by the growing interest in fundamental quantum-physical phenomena at energy scales corresponding to temperatures in the few millikelvin regime. However, a single filter concept is often insufficient to thermalize the electronic system to the cryogenic bath and eliminate spurious high frequency noise. Moreover, the available concepts often provide inadequate filtering to operate at temperatures below 10 mK, which are routinely available now in dilution cryogenic systems. Herein we provide a comprehensive analysis of commonly used filter types, introduce a novel compact filter type based on ferrite compounds optimized for the frequency range above 20 GHz, and develop an improved filtering scheme providing adaptable broad-band low-pass characteristic for cryogenic low-level and quantum measurement applications at temperatures down to few millikelvin.

AB - We demonstrate a coincidence velocity map imaging apparatus equipped with a novel time-stamping fast optical camera, Tpx3Cam, whose high sensitivity and nanosecond timing resolution allow for simultaneous position and time-of-flight detection. This single detector design is simple, flexible, and capable of highly differential measurements. We show detailed characterization of the camera and its application in strong field ionization experiments.

AB - Nowadays ptychographic tomography in the hard x-ray regime, i.e., at energies above about 2 keV, is a well-established measurement technique. At the Paul Scherrer Institut, currently two instruments are available: one is measuring at room temperature and atmospheric pressure, and the other, the so-called OMNY (tOMography Nano crYo) instrument, is operating at ultra-high vacuum and offering cryogenic sample temperatures down to 10 K. In this manuscript, we present the sample mounts that were developed for these instruments. Aside from excellent mechanical stability and thermal conductivity, they also offer highly reproducible mounting. Various types were developed for different kinds of samples and are presented in detail, including examples of how specimens can be mounted on these holders. We also show the first hard x-ray ptychographic tomography measurements of high-pressure frozen biological samples, in the present case Chlamydomonas cells, the related sample pins and preparation steps. For completeness, we present accessories such as transportation containers for both room temperature and cryogenic samples and a gripper mechanism for automatic sample changing. The sample mounts are not limited to x-ray tomography or hard x ray energies, and we believe that they can be very useful for other instrumentation projects.

AB - Shock tubes allow for the study of ultra-fast gas-phase reactions on the microsecond time scale. Because the repetition rate of the experiments is low, it is crucial to gain as much information as possible from each individual measurement. While reaction-time-resolved species concentration and temperature measurements with fast absorption methods are established, conventional laser induced fluorescence (LIF) measurements with pulsed lasers provide data only at a single reaction time. Therefore, fluorescence methods have rarely been used in shock-tube diagnostics. In this paper, a novel experimental concept is presented that allows reaction-time-resolved LIF measurements with one single laser pulse using a test section that is equipped with several optical ports. After the passage of the shock wave, the reactive mixture is excited along the center of the tube with a 266-nm laser beam directed through a window in the end wall of the shock tube. The emitted LIF signal is collected through elongated sidewall windows and focused onto the entrance slit of an imaging spectrometer coupled to an intensified CCD camera. The one-dimensional spatial resolution of the measurement translates into a reaction-time-resolved measurement while the species information can be gained from the spectral axis of the detected two dimensional image. Anisole pyrolysis was selected as the benchmark reaction to demonstrate the new apparatus. PMID- 29195353 TI - An optically referenced inclinometer with sub-microradian repeatability. AB - A pendulum inclinometer has been built and tested, suitable for measuring the deflection of the gravitational vertical to an accuracy of 1 MUrad. The design is based on measuring the differential capacitance between a pendulum bob and two closely spaced parallel electrodes. Two independent pendulums are oriented orthogonally to measure both coordinates. A collimated optical beam is stably attached to the inclinometer pair and provides a means for making stellar measurements relative to the gravitational vertical. For optimum performance, the inclinometer is operated at its null position by supporting the entire assembly on a rigid tilting plate. Good repeatability is a key feature of this inclinometer. PMID- 29195354 TI - Phase noise measurements with a cryogenic power-splitter to minimize the cross spectral collapse effect. AB - The cross-spectrum noise measurement technique enables enhanced resolution of spectral measurements. However, it has disadvantages, namely, increased complexity, inability of making real-time measurements, and bias due to the "cross-spectral collapse" (CSC) effect. The CSC can occur when the spectral density of a random process under investigation approaches the thermal noise of the power splitter. This effect can severely bias results due to a differential measurement between the investigated noise and the anti-correlated (phase inverted) noise of the power splitter. In this paper, we report an accurate measurement of the phase noise of a thermally limited electronic oscillator operating at room temperature (300 K) without significant CSC bias. We mitigated the problem by cooling the power splitter to liquid helium temperature (4 K). We quantify errors of greater than 1 dB that occur when the thermal noise of the oscillator at room temperature is measured with the power splitter at temperatures above 77 K. PMID- 29195355 TI - Aspheric optical surface profiling based on laser scanning and auto-collimation. AB - Nowadays the utilization of aspheric lenses has become more and more popular, enabling highly increased degree of freedom for optical design and simultaneously improving the performance of optical systems. Fast and accurate surface profiling of these aspheric components is a real demand in characterization and optimization of the optical systems. In this paper, a novel and simple surface profiler instrument is designed and developed to fulfill the ever increasing need of testing the axially symmetric aspheric surface. The proposed instrument is implemented based on a unique mapping between the position and rotation angle of the reflective mirror in optical path and the coordinate of reflection point on the surface during rapid laser beam scanning. High accuracy of the proposed surface profiling method is ensured by a high-resolution grating guide rail, indexing plate, and position sensitive detector based on laser auto-collimation and beam center-fitting. Testing the meridian line of both convex and concave surfaces has been experimentally demonstrated using the developed instrument. In comparison to tested results from conventional image measuring instruments and coordinate measuring machines, coefficient of determination better than 0.999 99 and RMS less than 1.5 MUm have been achieved, which validates the feasibility of this method. Analysis on the systematic error is beneficial to further improve its measurement accuracy. The presented instrument-essentially builds on the geometrical optics technique-provides a powerful tool to measure the aspheric surfaces quickly and accurately with stable structure and simple algorithm.

AB - Mass spectrometry imaging (MSI) has important applications in material research, biology, and medicine. The MSI method based on UV laser desorption/ionization (UVLDI) can obtain images of intact samples, but has a high level of molecular fragmentation. In this work, we report a new MSI instrument that uses a VUV laser (125.3 nm) as a desorption/ionization source to exploit its advantages of high single photon energy and small focus size. The new instrument was tested by the mass spectra of Nile red and FGB (Fibrinogen beta chain) samples and mass spectrometric images of a fly brain section. For the tested samples, the VUVDI method offers lower levels of molecular fragmentations and higher sensitivities than those of the UVLDI method and second ion mass spectrometry imaging method using a Bi3+ beam. The ablation crater produced by the focused VUV laser on a quartz plate has an area of 10 MUm2. The VUV laser is prepared based on the four wave mixing method using three collimated laser beams and a heated Hg cell. PMID- 29195357 TI - Calibration of imaging plate detectors to mono-energetic protons in the range 1 200 MeV. AB - Responses of Fuji Imaging Plates (IPs) to proton have been measured in the range 1-200 MeV. Mono-energetic protons were produced with the 15 MV ALTO-Tandem accelerator of the Institute of Nuclear Physics (Orsay, France) and, at higher energies, with the 200-MeV isochronous cyclotron of the Institut Curie-Centre de Protontherapie d'Orsay (Orsay, France). The experimental setups are described and the measured photo-stimulated luminescence responses for MS, SR, and TR IPs are presented and compared to existing data. For the interpretation of the results, a sensitivity model based on the Monte Carlo GEANT4 code has been developed. It enables the calculation of the response functions in a large energy range, from 0.1 to 200 MeV. Finally, we show that our model reproduces accurately the response of more complex detectors, i.e., stack of high-Z filters and IPs, which could be of great interest for diagnostics of Petawatt laser accelerated particles.

AB - A novel development is made here by inventing panorama single-cell mega-size electrochemical etching (MS-ECE) chamber systems for processing panorama position sensitive mega-size polycarbonate ion image detectors (MS-PCIDs) of potential for many neutron and ion detection applications in particular hydrogen ions or proton tracks and images detected for the first time in polycarbonates in this study. The MS-PCID is simply a large polycarbonate sheet of a desired size. The single cell MS-ECE invented consists of two large equally sized transparent Plexiglas sheets as chamber walls holding a MS-PCID and the ECE chamber components tightly together. One wall has a large flat stainless steel electrode (dry cell) attached to it which is directly in contact with the MS-PCID and the other wall has a rod electrode with two holes to facilitate feeding and draining out the etching solution from the wet cell. A silicon rubber washer plays the role of the wet cell to hold the etchant and the electrical insulator to isolate the dry cell from the wet cell. A simple 50 Hz-HV home-made generator provides an adequate field strength through the two electrodes across the MS-ECE chamber. Two panorama single-cell MS-ECE chamber systems (circular and rectangular shapes) constructed were efficiently applied to processing the MS-PCIDs for 4pi ion emission image detection of different gases in particular hydrogen ions or protons in a 3.5 kJ plasma focus device (PFD as uniquely observed by the unaided eyes). The panorama MS-PCID/MS-ECE image detection systems invented are novel with high potential for many applications in particular as applied to 4pi panorama ion emission angular distribution image detection studies in PFD space, some results of which are presented and discussed. PMID- 29195359 TI - Improved accuracy of capacitive sensor-based micro-angle measurement with angular to-linear displacement conversion. AB - This paper presents a capacitive sensor-based micro-angle measurement (CSMAM) method that uses an angular-to-linear displacement conversion to achieve high accuracy. The principal and secondary error components of CSMAMs are modeled and analyzed to reveal their impacts on the measurement accuracy. The theoretical accuracies of six types of commonly used CSMAMs are analyzed to determine the optimum configuration of capacitive sensors for 1D and 2D micro-angle measurements. An angular-to-linear displacement conversion method with a linear motional stage and a hemisphere decoupler is used to eliminate the principal error of CSMAM. Experimental results indicate that the optimized CSMAM can achieve accuracies of 0.157 arc sec and 0.052 arc sec in the ranges of +/-900 arc sec and +/-300 arc sec, respectively, in the case that the effective length of the rotation arm is 100 mm and the linear displacement measurement accuracy of the capacitive sensor is 2 nm. These results can be used as a reference to further improve CSMAM designs and achieve high accuracy in a large measurement range, for use in a wide range of precision engineering applications including angle metrology, micro- and nano-radian angle generators, beam steering mechanisms, and high-performance precision stages. PMID- 29195360 TI - Biased four-point probe resistance. AB - The implications of switching the current polarity in a four-point probe resistance measurement are presented. We demonstrate that, during the inversion of the applied current, any change in the voltage V produced by a continuous drop of the sample temperature T will induce a bias in the temperature-dependent DC resistance. The analytical expression for the bias is deduced and written in terms of the variations of the measured voltages with respect to T and by the variations of T with respect to time t. Experimental data measured on a superconducting Nb thin film confirm that the bias of the normal-state resistance monotonically increases with the cooling rate dT/dt while keeping fixed dV/dT; on the other hand, the bias increases with dV/dT, reaching values up to 13% with respect to the unbiased resistance obtained at room temperature. PMID- 29195361 TI - Modular injector integrated linear apparatus with motion profile optimization for spatial atomic layer deposition. AB - A spatial atomic layer deposition apparatus integrated with a modular injector and a linear motor has been designed. It consists of four parts: a precursor delivery manifold, a modular injector, a reaction zone, and a driving unit. An injector with multi-layer structured channels is designed to help improve precursor distribution homogeneity. During the back and forth movement of the substrate at high speed, the inertial impact caused by jerk and sudden changes of acceleration will degrade the film deposition quality. Such residual vibration caused by inertial impact will aggravate the fluctuation of the gap distance between the injector and the substrate in the deposition process. Thus, an S curve motion profile is implemented to reduce the large inertial impact, and the maximum position error could be reduced by 84%. The microstructure of the film under the S-curve motion profile shows smaller root-mean-square and scanning voltage amplitude under an atomic force microscope, which verifies the effectiveness of the S-curve motion profile in reducing the residual vibration and stabilizing the gap distance between the injector and the substrate. The film deposition rate could reach 100 nm/min while maintaining good uniformity without obvious periodic patterns on the surface. PMID- 29195362 TI - A novel optical rotary encoder with eccentricity self-detection ability. AB - Eccentricity error is the main error source of optical rotary encoders. Real-time detection and compensation of the eccentricity error is an effective way of improving the accuracy of rotary optical encoders. In this paper, a novel rotary optical encoder is presented to realize eccentricity self-detection. The proposed encoder adopts a spider-web-patterned scale grating as a measuring standard which is scanned by a dual-head scanning unit. Two scanning heads of the dual-head scanning unit, which are arranged orthogonally, have the function of scanning the periodic pattern of the scale grating along the angular and radial directions, respectively. By this means, synchronous measurement of angular and radial displacements of the scale grating is realized. This paper gives the details of the operating principle of the rotary optical encoder, developing and testing work of a prototype. The eccentricity self-detection result agrees well with the result measured by an optical microscope. The experimental result preliminarily proves the feasibility and effectiveness of the proposed optical encoder. PMID- 29195363 TI - Hyperspectral imaging with deformable gratings fabricated with metal-elastomer nanocomposites. AB - We report the fabrication and characterization of a simple and compact hyperspectral imaging setup based on a stretchable diffraction grating made with a metal-polymer nanocomposite. The nanocomposite is produced by implanting Ag clusters in a poly(dimethylsiloxane) film by supersonic cluster beam implantation. The deformable grating has curved grooves and is imposed on a concave cylindrical surface, thus obtaining optical power in two orthogonal directions. Both diffractive and optical powers are obtained by reflection, thus realizing a diffractive-catoptric optical device. This makes it easier to minimize aberrations. We prove that, despite the extended spectral range and the simplified optical scheme, it is actually possible to work with a traditional CCD sensor and achieve a good spectral and spatial resolution. PMID- 29195364 TI - Injector design for liner-on-target gas-puff experiments. AB - We present the design of a gas-puff injector for liner-on-target experiments. The injector is composed of an annular high atomic number (e.g., Ar and Kr) gas and an on-axis plasma gun that delivers an ionized deuterium target. The annular supersonic nozzle injector has been studied using Computational Fluid Dynamics (CFD) simulations to produce a highly collimated (M > 5), ~1 cm radius gas profile that satisfies the theoretical requirement for best performance on ~1-MA current generators. The CFD simulations allowed us to study output density profiles as a function of the nozzle shape, gas pressure, and gas composition. We have performed line-integrated density measurements using a continuous wave (CW) He-Ne laser to characterize the liner gas density. The measurements agree well with the CFD values. We have used a simple snowplow model to study the plasma sheath acceleration in a coaxial plasma gun to help us properly design the target injector. PMID- 29195365 TI - A burn depth detection system based on near infrared spectroscopy and ensemble learning. AB - Near infrared (NIR) spectroscopy can effectively detect the changes in the burned tissue. However, due to the complex relationship between the spectral signals and the burn depth, simple methods of data analysis are difficult to solve this problem effectively. Therefore, in this paper, a machine learning method is introduced into the NIR spectral signal analysis, which is used to establish the relationship between NIR spectral signals and burn depth. First, based on the intensity of the spectral signal and the diffuse reflection theory, the optical properties that can reflect the change of burned tissue are extracted. And then the chained-agent genetic algorithm (CAGA) optimized support vector regression (SVR) is applied to establish a regression model between the optical property parameters and burn depth. Finally, the porcine model was used for verification. The experimental results demonstrate that the proposed CAGA-SVR integrated inversion model with optical properties can perform accurate inversion of burn depth and provide a reference for doctors.

AB - We describe the design and control of a four legged walking robot, 45 g in weight and 130 mm * 105 mm * 25 mm in size. Each leg consists of two piezoelectric bimorph actuators that are bonded at the free end by a flexure and an end effector. The robot generates stick-slip locomotion when applying sawtooth shaped voltage signals. Friction between legs and a contact surface is analyzed by using the Coulomb friction model. Locomotion characteristics are measured in several experiments. The robot was driven with frequencies up to 75 Hz, and a maximum velocity of 65 mm/s was obtained at two frequencies: 45 Hz with 190 Vpp driving voltage and 60 Hz with 170 Vpp driving voltage, respectively. PMID- 29195367 TI - A versatile apparatus for two-dimensional atomtronic quantum simulation. AB - We report on the implementation of a novel optical setup for generating high resolution customizable potentials to address ultracold bosonic atoms in two dimensions. Two key features are developed for this purpose. The customizable potential is produced with a direct image of a spatial light modulator, conducted with an in-vacuum imaging system of high numerical aperture. Custom potentials are drawn over an area of 600*400 MUm with a resolution of 0.9 MUm. The second development is a two-dimensional planar trap for atoms with an aspect ratio of 900 and spatial extent of Rayleigh range 1.6 * 1.6 mm, providing near-ballistic in-planar movement. We characterize the setup and present a brief catalog of experiments to highlight the versatility of the system. PMID- 29195368 TI - Simple measuring rod method for the coaxiality of serial holes. AB - Aiming at the rapid coaxiality measurement of serial hole part with a small diameter, a coaxiality measuring rod for each layer hole with a single LDS (laser displacement sensor) is proposed. This method does not require the rotation angle information of the rod, and the coaxiality of serial holes can be calculated from the measured values of LDSs after randomly rotating the measuring rod several times. With the mathematical model of the coaxiality measuring rod, each factor affecting the accuracy of coaxiality measurement is analyzed by simulation, and the installation accuracy requirements of the measuring rod and LDSs are presented. In the tolerance of a certain installation error of the measuring rod, the relative center of the hole is calculated by setting the over-determined nonlinear equations of the fitting circles of the multi-layer holes. In experiment, coaxiality measurement accuracy is realized by a 16 MUm precision LDS, and the validity of the measurement method is verified. The manufacture and measurement requirements of the coaxiality measuring rod are low, by changing the position of LDSs in the measuring rod, the serial holes with different sizes and numbers can be measured. The rapid coaxiality measurement of parts can be easily implemented in industrial sites. PMID- 29195370 TI - Note: Retrofitting an analog spectrometer for high resolving power in NUV-NIR. AB - We demonstrate how an older spectrometer designed for photographic films can be efficiently retrofitted with a narrow laser-cut slit and a modern MUm-pixel-size imaging CMOS camera, yielding sub-pm resolution in the broad near ultraviolet to near infrared (NUV-NIR) spectral range. Resolving power approaching 106 is achieved. Such digital retrofitting of an analog instrument is practical for research and teaching laboratories.

AB - CAT-ACT-the hard X-ray beamline for CATalysis and ACTinide/radionuclide research at the KIT synchrotron radiation facility ANKA-is dedicated to X-ray spectroscopy, including "flux hungry" photon-in/photon-out and correlative techniques and combines state-of-the-art optics with a unique infrastructure for radionuclide and catalysis research. Measurements can be performed at photon energies varying between 3.4 keV and 55 keV, thus encompassing the actinide M- and L-edge or potassium K-edge up to the K-edges of the lanthanide series such as cerium. Well-established X-ray absorption fine structure spectroscopy in transmission and fluorescence detection modes is available in combination with high energy-resolution X-ray emission spectroscopy or X-ray diffraction techniques. The modular beamline design with two alternately operated in-line experimental stations enables sufficient flexibility to adapt sample environments and detection systems to many scientific challenges. The ACT experimental station focuses on various aspects of nuclear waste disposal within the mission of the Helmholtz association to contribute to the solution of one of the greatest scientific and social challenges of our time-the safe disposal of heat producing, highly radioactive waste forms from nuclear energy production. It augments present capabilities at the INE-Beamline by increasing the flux and extending the energy range into the hard X-ray regime. The CAT experimental station focuses on catalytic materials, e.g., for energy-related and exhaust gas catalysis. Characterization of catalytically active materials under realistic reaction conditions and the development of in situ and operando cells for sample environments close to industrial reactors are essential aspects at CAT. PMID- 29195372 TI - The nanopore mass spectrometer. AB - We report the design of a mass spectrometer featuring an ion source that delivers ions directly into high vacuum from liquid inside a capillary with a sub micrometer-diameter tip. The surface tension of water and formamide is sufficient to maintain a stable interface with high vacuum at the tip, and the gas load from the interface is negligible, even during electrospray. These conditions lifted the usual requirement of a differentially pumped system. The absence of a background gas also opened up the possibility of designing ion optics to collect and focus ions in order to achieve high overall transmission and detection efficiencies. We describe the operation and performance of the instrument and present mass spectra from solutions of salt ions and DNA bases in formamide and salt ions in water. The spectra show singly charged solute ions clustered with a small number of solvent molecules. PMID- 29195373 TI - Air sampling unit for breath analyzers. AB - The paper presents a portable breath sampling unit (BSU) for human breath analyzers. The developed unit can be used to probe air from the upper airway and alveolar for clinical and science studies. The BSU is able to operate as a patient interface device for most types of breath analyzers. Its main task is to separate and to collect the selected phases of the exhaled air. To monitor the so called I, II, or III phase and to identify the airflow from the upper and lower parts of the human respiratory system, the unit performs measurements of the exhaled CO2 (ECO2) in the concentration range of 0%-20% (0-150 mm Hg). It can work in both on-line and off-line modes according to American Thoracic Society/European Respiratory Society standards. A Tedlar bag with a volume of 5 dm3 is mounted as a BSU sample container. This volume allows us to collect ca. 1 25 selected breath phases. At the user panel, each step of the unit operation is visualized by LED indicators. This helps us to regulate the natural breathing cycle of the patient. There is also an operator's panel to ensure monitoring and configuration setup of the unit parameters. The operation of the breath sampling unit was preliminarily verified using the gas chromatography/mass spectrometry (GC/MS) laboratory setup. At this setup, volatile organic compounds were extracted by solid phase microextraction. The tests were performed by the comparison of GC/MS signals from both exhaled nitric oxide and isoprene analyses for three breath phases. The functionality of the unit was proven because there was an observed increase in the signal level in the case of the III phase (approximately 40%). The described work made it possible to construct a prototype of a very efficient breath sampling unit dedicated to breath sample analyzers. PMID- 29195374 TI - Huddle test measurement of a near Johnson noise limited geophone. AB - In this paper, the sensor noise of two geophone configurations (L-22D and L-4C geophones from Sercel with custom built amplifiers) was measured by performing two huddle tests. It is shown that the accuracy of the results can be significantly improved by performing the huddle test in a seismically quiet environment and by using a large number of reference sensors to remove the seismic foreground signal from the data. Using these two techniques, the measured sensor noise of the two geophone configurations matched the calculated predictions remarkably well in the bandwidth of interest (0.01 Hz-100 Hz). Low noise operational amplifiers OPA188 were utilized to amplify the L-4C geophone to give a sensor that was characterized to be near Johnson noise limited in the bandwidth of interest with a noise value of 10-11 m/Hz at 1 Hz. PMID- 29195375 TI - Sensor fault diagnosis of aero-engine based on divided flight status. AB - Fault diagnosis and safety analysis of an aero-engine have attracted more and more attention in modern society, whose safety directly affects the flight safety of an aircraft. In this paper, the problem concerning sensor fault diagnosis is investigated for an aero-engine during the whole flight process. Considering that the aero-engine is always working in different status through the whole flight process, a flight status division-based sensor fault diagnosis method is presented to improve fault diagnosis precision for the aero-engine. First, aero engine status is partitioned according to normal sensor data during the whole flight process through the clustering algorithm. Based on that, a diagnosis model is built for each status using the principal component analysis algorithm. Finally, the sensors are monitored using the built diagnosis models by identifying the aero-engine status. The simulation result illustrates the effectiveness of the proposed method. PMID- 29195376 TI - Measurement of contact angles at room temperature in high magnetic field. AB - The contact angle (CA) goniometer adaptable to a superconducting magnet was developed based on the sessile drop method. The goniometer mainly consisted of the sampling system, the supporting system, and the image acquisition system. Some improvements were taken to avoid the effects of the magnetic field (MF) on the CA measurement. As an example, the CAs of water on two substrates of silica and polymethyl methacrylate (PMMA) were measured using the goniometer. The results with and without a MF showed a good repeatability and reliability. Additionally, the MF was found to reduce the CA of water, which probably stemmed from the change of the surface tension in the MF. The CA goniometer will become an important tool which is used to study the wettability of liquids on a solid in the MF. PMID- 29195377 TI - Portable device for generation of ultra-pure water vapor feeds. AB - A portable device for the generation of co-feeds of water vapor has been designed, constructed, and evaluated for flexible use as an add-on component to laboratory chemical reactors. The vapor is formed by catalytic oxidation of hydrogen, which benefits the formation of well-controlled minute concentrations of ultra-pure water. Analysis of the effluent stream by on-line mass spectrometry and Fourier transform infrared spectroscopy confirms that water vapor can be, with high precision, generated both rapidly and steadily over extended periods in the range of 100 ppm to 3 vol. % (limited by safety considerations) using a total flow of 100 to 1500 ml/min at normal temperature and pressure. Further, the device has been used complementary to a commercial water evaporator and mixing system to span water concentrations up to 12 vol. %. Finally, an operando diffuse reflective infrared Fourier transform spectroscopic measurement of palladium catalysed methane oxidation in the absence and presence of up to 1.0 vol. % water has been carried out to demonstrate the applicability of the device for co feeding well-controlled low concentrations of water vapor to a common type of spectroscopic experiment. The possibilities of creating isotopically labeled water vapor as well as using tracer gases for dynamic experiments are discussed.

The diagnostic is composed of 128 lines of sight covering a 20 cm diameter section and an acquisition rate up to 1 MHz. The measurements are done in the visible spectrum using silicon photomultiplier arrays that require a lower amplification voltage than photomultiplier tubes for similar gains and have a fast response. Tomographic reconstruction of a rotating plasma mode is shown to illustrate the capabilities of the diagnostic. PMID- 29195380 TI - Signal processing and analysis for copper layer thickness measurement within a large variation range in the CMP process. AB - In the copper (Cu) chemical mechanical planarization (CMP) process, accurate determination of a process reaching the end point is of great importance. Based on the eddy current technology, the in situ thickness measurement of the Cu layer is feasible. Previous research studies focus on the application of the eddy current method to the metal layer thickness measurement or endpoint detection. In this paper, an in situ measurement system, which is independently developed by using the eddy current method, is applied to the actual Cu CMP process. A series of experiments are done for further analyzing the dynamic response characteristic of the output signal within different thickness variation ranges. In this study, the voltage difference of the output signal is used to represent the thickness of the Cu layer, and we can extract the voltage difference variations from the output signal fast by using the proposed data processing algorithm. The results show that the voltage difference decreases as thickness decreases in the conventional measurement range and the sensitivity increases at the same time. However, it is also found that there exists a thickness threshold, and the correlation is negative, when the thickness is more than the threshold. Furthermore, it is possible that the in situ measurement system can be used within a larger Cu layer thickness variation range by creating two calibration tables. PMID- 29195381 TI - In situ calibration of neutron activation system on the large helical device. AB - In situ calibration of the neutron activation system on the Large Helical Device (LHD) was performed by using an intense 252Cf neutron source. To simulate a ring shaped neutron source, we installed a railway inside the LHD vacuum vessel and made a train loaded with the 252Cf source run along a typical magnetic axis position. Three activation capsules loaded with thirty pieces of indium foils stacked with total mass of approximately 18 g were prepared. Each capsule was irradiated over 15 h while the train was circulating. The activation response coefficient (9.4 +/- 1.2) * 10-8 of 115In(n, n')115mIn reaction obtained from the experiment is in good agreement with results from three-dimensional neutron transport calculations using the Monte Carlo neutron transport simulation code 6. The activation response coefficients of 2.45 MeV birth neutron and secondary 14.1 MeV neutron from deuterium plasma were evaluated from the activation response coefficient obtained in this calibration experiment with results from three dimensional neutron calculations using the Monte Carlo neutron transport simulation code 6. PMID- 29195382 TI - A dynamic monitoring approach for the surface morphology evolution measurement of plasma facing components by means of speckle interferometry. AB - Plasma Facing Components (PFCs) in a magnetically confined fusion plasma device will be exposed to high heat load and particle fluxes, and it would cause PFCs' surface morphology to change due to material erosion and redeposition from plasma wall interactions. The state of PFCs' surface condition will seriously affect the performance of long-pulse or steady state plasma discharge in a tokamak; it will even constitute an enormous threat to the operation and the safety of fusion plasma devices. The PFCs' surface morphology evolution measurement could provide important information about PFCs' real-time status or damage situation and it would help to a better understanding of the plasma wall interaction process and mechanism. Meanwhile through monitoring the distribution of dust deposition in a tokamak and providing an upper limit on the amount of loose dust, the PFCs' surface morphology measurement could indirectly contribute to keep fusion operational limits and fusion device safety. Aiming at in situ dynamic monitoring PFCs' surface morphology evolution, a laboratory experimental platform DUT-SIEP (Dalian University of Technology-speckle interferometry experimental platform) based on the speckle interferometry technique has been constructed at Dalian University of Technology (DUT) in China. With directional specific designing and focusing on the real detection condition of EAST (Experimental Advanced Superconducting Tokamak), the DUT-SIEP could realize a variable measurement range, widely increased from 0.1 MUm to 300 MUm, with high spatial resolution (<1 mm) and ultra-high time resolution (<2 s for EAST measuring conditions). Three main components of the DUT-SIEP are all integrated and synchronized by a time schedule control and data acquisition terminal and coupled with a three dimensional phase unwrapping algorithm, the surface morphology information of target samples can be obtained and reconstructed in real-time. A local surface morphology of the real divertor tiles adopted from EAST has been measured, and the feasibility and reliability of this new experimental platform have been demonstrated.

AB - Electrical applications require the development of electric field sensors that can reproduce vector electric field waveforms with a very large spectral width ranging from 50 Hz to at least 70 MHz. This makes it possible to measure both the normal operation modes of electrical components and abnormal behaviors such as the corona emission and partial discharges. In this work, we aim to develop a fully dielectric sensor capable of measuring two components of the electric field using a wide class of optical crystals including anisotropic ones, whereas most of the efforts in this field have been devoted to isotropic crystals. We report the results of the measurements performed at 50 Hz and with a lightning impulse, to validate the sensor. PMID- 29195384 TI - THz-pump and X-ray-probe sources based on an electron linac. AB - We describe a compact THz-pump and X-ray-probe beamline, based on an electron linac, for ultrafast time-resolved diffraction applications. Two high-energy electron (gamma > 50) bunches, 5 ns apart, impinge upon a single-foil or multifoil radiator and generate THz radiation and X-rays simultaneously. The THz pulse from the first bunch is synchronized to the X-ray beam of the second bunch by using an adjustable optical delay of a THz pulse. The peak power of THz radiation from the multifoil radiator is estimated to be 0.14 GW for a 200 pC well-optimized electron bunch. GEANT4 simulations show that a carbon foil with a thickness of 0.5-1.0 mm has the highest yield of 10-20 keV hard X-rays for a 25 MeV beam, which is approximately 103 photons/(keV pC-electrons) within a few degrees of the polar angle. A carbon multifoil radiator with 35 foils (25 MUm thick each) can generate close to 103 hard X-rays/(keV pC-electrons) within a 2 degrees acceptance angle. With 200 pC charge and a 100 Hz repetition rate, we can generate 107 X-rays per 1 keV energy bin per second or 105 X-rays per 1 keV energy bin per pulse. The longitudinal time profile of an X-ray pulse ranges from 400 to 600 fs depending on the acceptance angle. The broadening of the time duration of an X-ray pulse is observed owing to its diverging effect. A double crystal monochromator will be used to select and transport the desired X-rays to the sample. The heating of the radiators by an electron beam is negligible because of the low beam current.

AB - In order to accurately measure the flow rate under the low yield horizontal well conditions, an auto-cumulative flowmeter (ACF) was proposed. Using the proposed flowmeter, the oil flow rate in horizontal oil-water two-phase segregated flow can be finely extracted. The computational fluid dynamics software Fluent was used to simulate the fluid of the ACF in oil-water two-phase flow. In order to calibrate the simulation measurement of the ACF, a novel oil flow rate measurement method was further proposed. The models of the ACF were simulated to obtain and calibrate the oil flow rate under different total flow rates and oil cuts. Using the finite-element method, the structure of the seven conductance probes in the ACF was simulated. The response values for the probes of the ACF under the conditions of oil-water segregated flow were obtained. The experiments for oil-water segregated flow under different heights of the oil accumulation in horizontal oil-water two-phase flow were carried out to calibrate the ACF. The validity of the oil flow rate measurement in horizontal oil-water two-phase flow was verified by simulation and experimental results. PMID- 29195386 TI - Fitting a defect non-linear model with or without prior, distinguishing nuclear reaction products as an example. AB - Fitting a parametrized function to data is important for many researchers and scientists. If the model is non-linear and/or defect, it is not trivial to do correctly and to include an adequate uncertainty analysis. This work presents how the Levenberg-Marquardt algorithm for non-linear generalized least squares fitting can be used with a prior distribution for the parameters and how it can be combined with Gaussian processes to treat model defects. An example, where three peaks in a histogram are to be distinguished, is carefully studied. In particular, the probability r1 for a nuclear reaction to end up in one out of two overlapping peaks is studied. Synthetic data are used to investigate effects of linearizations and other assumptions. For perfect Gaussian peaks, it is seen that the estimated parameters are distributed close to the truth with good covariance estimates. This assumes that the method is applied correctly; for example, prior knowledge should be implemented using a prior distribution and not by assuming that some parameters are perfectly known (if they are not). It is also important to update the data covariance matrix using the fit if the uncertainties depend on the expected value of the data (e.g., for Poisson counting statistics or relative uncertainties). If a model defect is added to the peaks, such that their shape is unknown, a fit which assumes perfect Gaussian peaks becomes unable to reproduce the data, and the results for r1 become biased. It is, however, seen that it is possible to treat the model defect with a Gaussian process with a covariance function tailored for the situation, with hyper-parameters determined by leave one-out cross validation. The resulting estimates for r1 are virtually unbiased, and the uncertainty estimates agree very well with the underlying uncertainty.

AB - Photoelasticity and caustics methods are extensively used in the history of dynamic fracture mechanics. However, there is little work for the combination of them in the same experiment associated with high loading rate in extreme conditions. In the present work, it is the first time to build a simultaneous measurement system which can use photoelasticity and caustics methods at the same instant for in situ optical investigations of blast-induced dynamic fracture. To illustrate the capability of this system, an explosion experiment using a 2D epoxy plate is conducted, yielding consistent results between two methods. This novel system provides rich experimental data including local-field information for the crack tip and full-field information for blasting waves. PMID- 29195388 TI - Saturation of the photoneutralization of a H- beam in continuous operation. AB - An unprecedented, greater than 50%, photodetachment rate is obtained on a H- beam in the continuous regime. The key element of the experimental setup is a medium finesse optical cavity, suspended around the anion beam, which makes it possible to recycle the photon flux in the interaction region, at the crossing between the anion and laser beams. The cavity is injected by a narrow-linewidth ytterbium doped fibre laser, at the wavelength 1064 nm. The light power stored in the cavity is about 14 kW for 24 W of input light power. Similar greater-than-50% photo-neutralization efficiencies can be contemplated for beams with kinetic energies much larger than 1.2 keV of the presently used H- beam, given the fact that the stored light power can be increased, for larger beam diameters, by several orders of magnitude. The technique can thus be relied on to design novel D0 injectors, for fusion reactors, with a much better efficiency than the molecular-collision based injectors presently developed for ITER. It can also be applied to the production of neutral beams of any species that can be conveniently prepared in the form of an anion beam, provided that efficient light power storage can be achieved for the corresponding photodetachment wavelength. PMID- 29195389 TI - Multiplexed fluctuation-dissipation-theorem calibration of optical tweezers inside living cells. AB - In order to apply optical tweezers-based force measurements within an uncharacterized viscoelastic medium such as the cytoplasm of a living cell, a quantitative calibration method that may be applied in this complex environment is needed. We describe an improved version of the fluctuation-dissipation-theorem calibration method, which has been developed to perform in situ calibration in viscoelastic media without prior knowledge of the trapped object. Using this calibration procedure, it is possible to extract values of the medium's viscoelastic moduli as well as the force constant describing the optical trap. To demonstrate our method, we calibrate an optical trap in water, in polyethylene oxide solutions of different concentrations, and inside living fission yeast (S. pombe). PMID- 29195390 TI - An embeddable optical strain gauge based on a buckled beam. AB - We report, for the first time, a low cost, compact, and novel mechanically designed extrinsic Fabry-Perot interferometer (EFPI)-based optical fiber sensor with a strain amplification mechanism for strain measurement. The fundamental design principle includes a buckled beam with a coated gold layer, mounted on two grips. A Fabry-Perot cavity is produced between the buckled beam and the endface of a single mode fiber (SMF). A ceramic ferrule is applied for supporting and orienting the SMF. The principal sensor elements are packaged and protected by two designed metal shells. The midpoint of the buckled beam will experience a deflection vertically when the beam is subjected to a horizontally/axially compressive displacement. It has been found that the vertical deflection of the beam at midpoint can be 6-17 times larger than the horizontal/axial displacement, which forms the basis of a strain amplification mechanism. The user-configurable buckling beam geometry-based strain amplification mechanism enables the strain sensor to achieve a wide range of strain measurement sensitivities. The designed EFPI was used to monitor shrinkage of a square brick of mortar. The strain was measured during the drying/curing stage. We envision that it could be a good strain sensor to be embedded in civil materials/structures under a harsh environment for a prolonged period of time. PMID- 29195391 TI - Micro-view-cell for phase behaviour and in situ Raman analysis of heterogeneously catalysed CO2 hydrogenation. AB - The operando study of CO2 hydrogenation is fundamental for a more rational optimisation of heterogeneous catalyst and reactor designs. To further complement the established efficiency of microreactors in reaction screening and bridge the operating and optical gaps, a micro-view-cell is presented for Raman microscopy at extreme conditions with minimum flow interference for genuine reaction analysis. Based on a flat sapphire window unit sealed in a plug flow-type enclosure holding the sample, the cell features unique 14 mm working distance and 0.36 numerical aperture and resists 400 degrees C and 500 bars. The use of the cell as an in situ tool for fast process monitoring and surface catalyst characterisation is demonstrated with phase behaviour and chemical analysis of the methanol synthesis over a commercial Cu/ZnO/Al2O3 catalyst. PMID- 29195392 TI - A millimeter magnetic trap for a dual (85Rb and 87Rb) species atom interferometer. AB - We present a magnetic trap for cold atoms near a surface of a millimeter-sized atom chip. The trap allows us to capture a large number of atoms with modest electrical currents (40 A) and to generate large magnetic gradients (>300 G cm 1). Here we report a mixture containing 6 * 109 atoms for the two rubidium isotopes 87Rb and 85Rb. This device does not require cleanroom facilities nor micro-machining technologies which makes its construction easier. In addition our design allows the implementation of an optical dipole trap with a laser beam passing through the chip. PMID- 29195393 TI - 1 MUs broadband frequency sweeping reflectometry for plasma density and fluctuation profile measurements. AB - Frequency swept reflectometry has reached the symbolic value of 1 MUs sweeping time; this performance has been made possible, thanks to an improved control of the ramp voltage driving the frequency source. In parallel, the memory depth of the acquisition system has been upgraded and can provide up to 200 000 signals during a plasma discharge. Additional improvements regarding the trigger delay determination of the acquisition and the voltage ramp linearity required by this ultra-fast technique have been set. While this diagnostic is traditionally dedicated to the plasma electron density profile measurement, such a fast sweeping rate can provide the study of fast plasma events and turbulence with unprecedented time and radial resolution from the edge to the core. Experimental results obtained on ASDEX Upgrade plasmas are presented to demonstrate the performances of the diagnostic. PMID- 29195394 TI - Note: A NDIR instrument for multicomponent gas detection using the galvanometer modulation. AB - The non-dispersive infrared (NDIR) instruments are widely applied to multicomponent gas detection in many fields. In this paper, a NDIR instrument using the galvanometer modulation is proposed, which has a common optical path for multicomponent gas detection. Compared with the conventional NDIR instrument using the chopper modulation, the proposed instrument with a simpler configuration has better detection efficiency and stability. The proposed instrument has been successfully used to measure the main gas components of vehicle emissions. The NDIR instrument using the galvanometer modulation has great potential for remote sensing application, where multicomponent gas is always spatially inhomogeneous. PMID- 29195395 TI - Simultaneous excitation of 85Rb and 87Rb isotopes inside a microfabricated vapor cell with double-RF fields for a chip-scale MZ magnetometer. AB - We report a novel method adopting two RF fields to simultaneously excite 85Rb and 87Rb isotopes for an MZ type atomic magnetometer. The MZ magnetometer adopts a 6 mm3 microfabricated vapor cell with natural abundance rubidium and 0.74 amagat nitrogen as buffer gas inside. The excessively broadened magnetic resonance signals of the two rubidium isotopes overlap with each other and cause deterioration in accuracy and sensitivity performance. To solve this problem, a Double-RF Field Method (DRFM) is proposed, which adopts two RF fields with a central frequency ratio of 2:3. Compared with traditional Single-RF Field Method (SRFM), the DRFM reduces the detection error by over 50% and improves the sensitivity by more than 10%. The experiments are conducted at three temperatures and under various static magnetic fields. Theoretical models are also built to discuss the performance improvement of the magnetometer by the DRFM against the SRFM. This method provides a way to improve the performance of chip-scale MZ atomic magnetometers with low cost natural abundance rubidium. PMID- 29195397 TI - Howland current source for high impedance load applications. AB - For Electrical Impedance Spectroscopy (EIS) applications, the Enhanced Howland Current Source (EHCS) is a popular choice as an excitation circuit due to its simplicity, reliability, and safety. However, its output impedance degradation at high frequency leads to errors that are unacceptable for high load impedance applications, such as the ones which use dry or microelectrodes. Based on a proposed mathematical model, this work designed an EHCS circuit which includes an output current buffer and frequency compensation. PSpice simulations were performed as proof of concept, and then the measured data were collected for comparison. For the proposed circuit, called here Load-in-the-Loop Compensated Enhanced Howland Source (LLC-EHCS), the results showed that the output current errors are lower than 1% up to 3.7 MHz over the load range of 560-2200 Omega and 1.2 MHz with 5.6 kOmega. On the other hand, for the case of the standard EHCS circuit, these frequencies are 170 and 80 kHz, respectively. Also, the output linear swing was found to be 3 times higher than the EHCS. It can be concluded that the proposed LLC-EHCS may be widely used as an excitation circuit for high load and wide bandwidth EIS applications. PMID- 29195396 TI - Note: A highly symmetrical piezoelectric motor with self-matching friction and large output force. AB - We present a new stacked TunaDrive motor with two intact piezoelectric stacks being spring-clamped by a pair of parallel highly polished zirconia ceramic rods. Compared with the earlier version we presented with five stacks, it has a simpler and more compact structure and is much easier to build. Although the usage of piezoelectric material is cut by ~35%, the motor can still provide a large output force of ~1.92 N, which is nearly the same as that of the earlier version. The simple and symmetrical structure, high rigidity, and large output force make the new motor an ideal tool for coarse approach with nanometer precision. PMID- 29195398 TI - Automatic emissive probe apparatus for efficient plasma potential measurements. AB - The improved inflection point method of emissive probe is the most accurate method for plasma potential measurements, but its manual operation is quite cumbersome and time-consuming. This paper describes the design and test of an automatic emissive probe apparatus for efficient plasma potential measurements. The apparatus consists of a computer controlled data acquisition (DAQ) card, a working circuit composed of a biasing unit and a heating unit, as well as the emissive probe. The main feature of the apparatus is that both the biasing scan and the heating scan of the probe are controlled by the computer program through analog outputs of the DAQ card, which easily realizes the required timing between the biasing and heating scans of the probe. The apparatus can automatically execute the improved inflection point method of emissive probe and give the plasma potential result. The advantages of high-accuracy, high-efficiency, and durability of probe filament make the apparatus promising for extensive use in plasma potential measurements. PMID- 29195399 TI - A pinhole camera for ultrahigh-intensity laser plasma experiments. AB - A pinhole camera is an important instrument for the detection of radiation in laser plasmas. It can monitor the laser focus directly and assist in the analysis of the experimental data. However, conventional pinhole cameras are difficult to use when the target is irradiated by an ultrahigh-power laser because of the high background of hard X-ray emission generated in the laser/target region. Therefore, an improved pinhole camera has been developed that uses a grazing incidence mirror that enables soft X-ray imaging while avoiding the effect of hard X-ray from hot dense plasmas. PMID- 29195400 TI - A novel AFM-based 5-axis nanoscale machine tool for fabrication of nanostructures on a micro ball. AB - This paper presents a novel atomic force microscopy (AFM)-based 5-axis nanoscale machine tool developed to fabricate nanostructures on different annuli of the micro ball. Different nanostructures can be obtained by combining the scratching trajectory of the AFM tip with the movement of the high precision air-bearing spindle. The center of the micro ball is aligned to be coincided with the gyration center of the high precision to guarantee the machining process during the rotating of the air-bearing spindle. Processing on different annuli of the micro ball is achieved by controlling the distance between the center of the micro ball and the rotation center of the AFM head. Nanostructures including square cavities, circular cavities, triangular cavities, and an annular nanochannel are machined successfully on the three different circumferences of a micro ball with a diameter of 1500 MUm. Moreover, the influences of the error motions of the high precision air-bearing spindle and the eccentric between the micro ball and the gyration center of the high precision air-bearing spindle on the processing position error on the micro ball are also investigated. This proposed machining method has the potential to prepare the inertial confinement fusion target with the expected dimension defects, which would advance the application of the AFM tip-based nanomachining approach. PMID- 29195401 TI - High speed displacement measurement based on electro-magnetic induction applied to electromagnetically driven ring expansion. AB - Investigating the mechanism of electromagnetic forming (EMF) becomes a hot topic in the field of metal forming. The high speed up to 200 m/s in EMF makes it a real challenge to capture the forming process. To this end, a new method for measuring displacement at high speed based on electromagnetic induction has been developed. Specifically this is used to measure the displacement of an expanding metal ring driven by a pulsed magnetic field; this is one of the basic EMF processes. The new method is simple and practical, and it combines high-speed response with adequate precision. The new measurement system consists of a printed circuit board (PCB) and a Rogowski probe. Eleven coaxial annular detecting probes are arranged in the PCB plate to acquire induced voltage at different positions, and a Rogowski probe is used to measure the current in the driving coil. The displacement of the ring is deduced by analyzing the output voltages of the detecting probes and the Rogowski probe. The feasibility of the method is verified by comparing the results with pictures from a high speed camera taken simultaneously. PMID- 29195402 TI - Flame exposure time on Langmuir probe degradation, ion density, and thermionic emission for flame temperature. AB - The paper examines the effect of exposure time of Langmuir probes in an atmospheric premixed methane-air flame. The effects of probe size and material composition on current measurements were investigated, with molybdenum and tungsten probe tips ranging in diameter from 0.0508 to 0.1651 mm. Repeated prolonged exposures to the flame, with five runs of 60 s, resulted in gradual probe degradations (-6% to -62% area loss) which affected the measurements. Due to long flame exposures, two ion saturation currents were observed, resulting in significantly different ion densities ranging from 1.16 * 1016 to 2.71 * 1019 m 3. The difference between the saturation currents is caused by thermionic emissions from the probe tip. As thermionic emission is temperature dependent, the flame temperature could thus be estimated from the change in current. The flame temperatures calculated from the difference in saturation currents (1734 1887 K) were compared to those from a conventional thermocouple (1580-1908 K). Temperature measurements obtained from tungsten probes placed in rich flames yielded the highest percent error (9.66%-18.70%) due to smaller emission current densities at lower temperatures. The molybdenum probe yielded an accurate temperature value with only 1.29% error. Molybdenum also demonstrated very low probe degradation in comparison to the tungsten probe tips (area reductions of 6% vs. 58%, respectively). The results also show that very little exposure time (<5 s) is needed to obtain a valid ion density measurement and that prolonged flame exposures can yield the flame temperature but also risks damage to the Langmuir probe tip. PMID- 29195403 TI - A dynamic point-load test for quantifying rock dynamic strength parameters. AB - The point-load test (PLT) has been widely used in the field and in the laboratory to estimate the strength of rock materials. The PLT is easy and quick to perform and it is suitable for samples with irregular shapes and therefore has found wide applications. The measured point-load strength (PLS) is considered as a strength index and it has been correlated to the rock compressive strength. To address the engineering applications where the loading is dynamic, the PLT is extended to its dynamic version in this study. The dynamic loading is exerted to the rock specimen using a split Hopkinson pressure bar system. Two conical steel platens are attached to the incident bar and transmitted bar, respectively, to apply the point load to the disc specimen. To enable quasi-static analysis, the pulse shaper technique is utilized to achieve the dynamic force balance. The flexibility of the dynamic PLT method is demonstrated by the application to a well-studied granitic rock-Laurentian granite. The correlation between the dynamic PLS and the dynamic strength of the same rock is established. PMID- 29195404 TI - Noise spectra in balanced optical detectors based on transimpedance amplifiers. AB - We present a thorough theoretical analysis and experimental study of the shot and electronic noise spectra of a balanced optical detector based on an operational amplifier connected in a transimpedance scheme. We identify and quantify the primary parameters responsible for the limitations of the circuit, in particular, the bandwidth and shot-to-electronic noise clearance. We find that the shot noise spectrum can be made consistent with the second-order Butterworth filter, while the electronic noise grows linearly with the second power of the frequency. Good agreement between the theory and experiment is observed; however, the capacitances of the operational amplifier input and the photodiodes appear significantly higher than those specified in manufacturers' datasheets. This observation is confirmed by independent tests. PMID- 29195405 TI - A polarization converting device for an interfering enhanced CPT atomic clock. AB - With interfering enhanced coherent population trapping (CPT) signals, a CPT atomic clock with improved frequency stability performance can be realized. We explore an optical device that converts single-polarized bichromatic light to left and right circularly polarized superposed bichromatic light to generate interfering enhanced CPT resonance with atoms. We have experimentally studied a tabletop CPT atomic clock apparatus with a microfabricated 87Rb atomic chip-scale cell, and the study results show that it is promising to realize a compact CPT atomic clock, even a chip-scale CPT atomic clock through microfabrication, with improved frequency stability performance. PMID- 29195406 TI - Semiconductor sharpeners providing a subnanosecond voltage rise time of GW-range pulses. AB - The article describes semiconductor sharpeners providing a subnanosecond voltage rise time of GW-range pulses. The sharpeners are made as stacks of series connected dynistor structures built into an oil-filled coaxial line with 48 Omega wave impedance at the place of an inner conductor. Two sequential sections of pulse sharpening are used. An input voltage pulse has the amplitude of 540 kV with the rise time of ~1.2 ns at 0.2-0.9 level from the amplitude and voltage rise rate of ~0.3 MV/ns. After pulse propagation through the sharpening sections, its rise time is reduced down to 360 ps, and the voltage rise rate is increased up to ~0.95 MV/ns. Peak power of the sharpened pulse is within the range of 4.5 5.5 GW. The sharpeners are tested at a pulse repetition frequency of up to 1 kHz. Sharpener operation is studied by numerical simulation methods. Experimental waveforms of output pulses and the corresponding calculated voltage-time dependences are in statistical agreement.

AB - The Colorado Solar Wind Experiment is a new device constructed at the Institute for Modeling Plasma, Atmospheres, and Cosmic Dust at the University of Colorado. A large cross-sectional Kaufman ion source is used to create steady state plasma flow to model the solar wind in an experimental vacuum chamber. The plasma beam has a diameter of 12 cm at the source, ion energies of up to 1 keV, and ion flows of up to 0.1 mA/cm2. Chamber pressure can be reduced to 4 * 10-5 Torr under operating conditions to suppress ion-neutral collisions and create a monoenergetic ion beam. The beam profile has been characterized by a Langmuir probe and an ion energy analyzer mounted on a two-dimensional translation stage. The beam profile meets the requirements for planned experiments that will study solar wind interaction with lunar magnetic anomalies, the charging and dynamics of dust in the solar wind, plasma wakes and refilling, and the wakes of topographic features such as craters or boulders. This article describes the technical details of the device, initial operation and beam characterization, and the planned experiments. PMID- 29195408 TI - A microfluidic sub-critical water extraction instrument. AB - This article discusses a microfluidic subcritical water extraction (SCWE) chip for autonomous extraction of amino acids from astrobiologically interesting samples. The microfluidic instrument is composed of three major components. These include a mixing chamber where the soil sample is mixed and agitated with the solvent (water), a subcritical water extraction chamber where the sample is sealed with a freeze valve at the chip inlet after a vapor bubble is injected into the inlet channels to ensure the pressure in the chip is in equilibrium with the vapor pressure and the slurry is then heated to <=200 degrees C in the SCWE chamber, and a filter or settling chamber where the slurry is pumped to after extraction. The extraction yield of the microfluidic SCWE chip process ranged from 50% compared to acid hydrolysis and 80%-100% compared to a benchtop microwave SCWE for low biomass samples. PMID- 29195409 TI - Triggering breakdown voltage of a high-current, two-electrode graphite gas switch assisted by ultraviolet pre-ionization. AB - A simple ultraviolet pre-ionization device designed to extend the lifetime of a high current, two-electrode graphite gas switch is described in this paper. The effects of UV-illumination on decreasing the triggering breakdown voltage were studied in theory and experiments. The results showed that UV-illumination can provide extra initial electrons on the cathode surface and make more air molecules in the excited state, which resulted in positive effects in reducing the triggering breakdown voltage and jitter. However, the effects became weak as the pressure increased; the reason of this phenomenon was that the ultraviolet absorption rate of the air molecules increased with the rising pressure, leading to a reduction of the ultraviolet intensity on the discharge gap. The largest value of the triggering breakdown voltage decreased was 13.5 kV under 100 kPa, and the reliable operation gap distance can extend another 1.2 mm, which was equivalent to 500 shots in our experiments. PMID- 29195410 TI - Invited Review Article: Measurements of the Newtonian constant of gravitation, G. AB - By many accounts, the Newtonian constant of gravitation G is the fundamental constant that is most difficult to measure accurately. Over the past three decades, more than a dozen precision measurements of this constant have been performed. However, the scatter of the data points is much larger than the uncertainties assigned to each individual measurement, yielding a Birge ratio of about five. Today, G is known with a relative standard uncertainty of 4.7 * 10-5, which is several orders of magnitudes greater than the relative uncertainties of other fundamental constants. In this article, various methods to measure G are discussed. A large array of different instruments ranging from the simple torsion balance to the sophisticated atom interferometer can be used to determine G. Some instruments, such as the torsion balance can be used in several different ways. In this article, the advantages and disadvantages of different instruments as well as different methods are discussed. A narrative arc from the historical beginnings of the different methods to their modern implementation is given. Finally, the article ends with a brief overview of the current state of the art and an outlook.

AB - The design, construction, and operation of a hand-held synchronously scanned, excitation-emission, double monochromator spectrometer is described. Data show that it is possible to record and display within minutes the fluorescence spectra and ratio of live/dead bacteria in situ. Excitation emission matrix contour plots display clearly bacteria fluorescence spectra before and after UV inactivation, respectively. The separation of the fluorescence band maxima of molecular components, such as tryptophan, tyrosine, and DNA, may be distinguished in the diffused fluorescence spectra of bacteria and mixtures. PMID- 29195412 TI - Radiation resistance of elastomeric O-rings in mixed neutron and gamma fields: Testing methodology and experimental results. AB - Materials and components employed in the presence of intense neutron and gamma fields are expected to absorb high dose levels that may induce deep modifications of their physical and mechanical properties, possibly causing loss of their function. A protocol for irradiating elastomeric materials in reactor mixed neutron and gamma fields and for testing the evolution of their main mechanical and physical properties with absorbed dose has been developed. Four elastomeric compounds used for vacuum O-rings, one fluoroelastomer polymer (FPM) based and three ethylene propylene diene monomer rubber (EPDM) based, presently available on the market have been selected for the test. One EPDM is rated as radiation resistant in gamma fields, while the other elastomers are general purpose products. Particular care has been devoted to dosimetry calculations, since absorbed dose in neutron fields, unlike pure gamma fields, is strongly dependent on the material composition and, in particular, on the hydrogen content. The products have been tested up to about 2 MGy absorbed dose. The FPM based elastomer, in spite of its lower dose absorption in fast neutron fields, features the largest variations of properties, with a dramatic increase in stiffness and brittleness. Out of the three EPDM based compounds, one shows large and rapid changes in the main mechanical properties, whereas the other two feature more stable behaviors. The performance of the EPDM rated as radiation resistant in pure gamma fields does not appear significantly better than that of the standard product. The predictive capability of the accelerated irradiation tests performed as well as the applicable concepts of threshold of radiation damage is discussed in view of the use of the examined products in the selective production of exotic species facility, now under construction at the Legnaro National Laboratories of the Italian Istituto Nazionale di Fisica Nucleare. It results that a careful account of dose rate effects and oxygen penetration in the material, both during test irradiations and in operating conditions, is needed to obtain reliable predictions. PMID- 29195413 TI - Control system of neoclassical tearing modes in real time on HL-2A tokamak. AB - The stability and performance of tokamak plasmas are routinely limited by various magneto-hydrodynamic instabilities, such as neoclassical tearing modes (NTMs). This paper presents a rather simple method to control the NTMs in real time (RT) on a tokamak, including the control principle of a feedback approach for RT suppression and stabilization for the NTMs. The control system combines Mirnov, electron cyclotron emission, and soft X-ray diagnostics used for determining the NTM positions. A methodology for fast detection of 2/1 or 3/2 NTM positions with 129 * 129 grid reconstruction is elucidated. The forty poloidal angles for steering the electron cyclotron resonance heating (ECRH)/electron cyclotron current drive launcher are used to establish the alignment of antenna mirrors with the center of the NTM and to ensure launcher emission intersecting with the rational surface of a magnetic island.

The 2/1 CTMs have been suppressed or stabilized by the ECRH power deposition on site or with the steerable launcher. PMID- 29195414 TI - A high precision flat crystal spectrometer compatible for ultra-high vacuum light source. AB - We report on a flat crystal spectrometer (FCS) featuring a differently pumped rotary feedthrough and double detectors connected to a crystal chamber by extendable bellows built at the Shanghai EBIT Laboratory. It was designed to overcome defects such as oil contamination, little distance from the detector to the crystal and others of an early FCS equipped at the same laboratory, but still keeps a large detectable angle range of detectors and brings new features and functions such as the Bond method measurement and double-crystal measurement which are based on the two-detector and large bellow design. This new FCS could cover an energy range of measurable photons from 570 eV to 10 keV and reach a vacuum better than 6 * 10-10 Torr and thus is compatible for coupling directly to ultra-high vacuum light sources. Off-line tests of the FCS were undertaken where Kalpha x-rays from solid titanium were measured and analyzed. Measurements of transitions in He-like argon ions were performed when the spectrometer was directly connected to Shanghai EBIT, and the width of the x-ray source was monitored simultaneously using an x-ray slit imaging system. An observed spectral line broadening was 0.869 eV corresponding to a resolving power of 3600, including Doppler broadening of the x-ray source. Taking account of the measured source width, we made simulations using the SHADOW 3 code and got a nominal resolving power of 6500 for the spectrometer. This high nominal resolving power is due to a longer distance from the crystal to the detector, comparing with that in the early FCS. PMID- 29195415 TI - A micro-CL system and its applications. AB - The computed laminography (CL) method is preferable to computed tomography for the non-destructive testing of plate-like objects. A micro-CL system is developed for three-dimensional imaging of plate-like objects. The details of the micro-CL system are described, including the system architecture, scanning modes, and reconstruction algorithm. The experiment results of plate-like fossils, insulated gate bipolar translator module, ball grid array packaging, and printed circuit board are also presented to demonstrate micro-CL's ability for 3D imaging of flat specimens and universal applicability in various fields. PMID- 29195416 TI - Non-native phonetic learning is destabilized by exposure to phonological variability before and after training. AB - Phonological variability is a key factor in many phonetic training studies, but it is unclear whether variability is universally helpful for learners. The current study explored variability and sleep consolidation in non-native phonetic learning. Two groups of participants were trained on a non-native contrast in one vowel context (/u/) and differed in whether they were also tested on an untrained context (/i/). Participants exposed to two vowels during the test were less accurate in perception of trained speech sounds and showed no overnight improvement. These findings suggest that introducing variability even in test phases may destabilize learning and prevent consolidation-based performance improvements.

AB - Resonant ultrasound spectroscopy (RUS) is the state-of-the-art method used to investigate the elastic properties of anisotropic solids. Recently, RUS was applied to measure human cortical bone, an anisotropic material with low Q-factor (20), which is challenging due to the difficulty in retrieving resonant frequencies. Determining the precision of the estimated stiffness constants is not straightforward because RUS is an indirect method involving minimizing the distance between measured and calculated resonant frequencies using a model. This work was motivated by the need to quantify the errors on stiffness constants due to different error sources in RUS, including uncertainties on the resonant frequencies and specimen dimensions and imperfect rectangular parallelepiped (RP) specimen geometry. The errors were first investigated using Monte Carlo simulations with typical uncertainty values of experimentally measured resonant frequencies and dimensions assuming a perfect RP geometry. Second, the exact specimen geometry of a set of bone specimens were recorded by synchrotron radiation micro-computed tomography. Then, a "virtual" RUS experiment is proposed to quantify the errors induced by imperfect geometry. Results show that for a bone specimen of ~1 degrees perpendicularity and parallelism errors, an accuracy of a few percent ( <6.2%) for all the stiffness constants and engineering moduli is achievable. PMID- 29195418 TI - Poro-acoustoelastic constants based on Pade approximation. AB - Stress-induced velocity variations for porous rocks are generally characterized by a strong nonlinear dependence on stress associated with complex deformations under loading. The classical theory of poro-acoustoelasticity with high-order elastic constants is based on the Taylor expansion of the strain energy function, encountering problems of divergence and limitless elastic wave velocities in describing stress-associated velocity variations, especially for high effective stresses. The extension of the theory beyond the high-order elastic constants based on the Pade approximation to the strain energy function is addressed in this article. The resultant acoustoelastic constants are characteristics of a reasonable theoretical limit in elastic wave velocities with increasing effective stresses, avoiding some of the problems associated with high-order elastic constants such as decreasing moduli with increasing effective pressure at high effective pressure, possibly implying the microstructural dependence of elastic constants. That is, the loading stress increases strain energy and wave velocity, but also induces frame-related attenuation, which in turn reduces stiffness and elastic constants. The Pade nonlinear constants can be reduced for low effective stresses to the conventional acoustoelastic constants based on the Taylor expansion. Theoretical results are compared with ultrasonic measurements for a perfectly elastic crystal, topaz (Al2SiO4F2), and a porous rock, demonstrating that the Pade-approximation-based acoustoelasticity gives a more accurate description of stress-associated velocity variations, especially for higher effective stresses. PMID- 29195419 TI - Finite difference time domain modelling of a point-excited elastic plate radiating into an acoustic cavity. AB - Finite difference time domain (FDTD) models are developed to solve the vibroacoustic problem of a thin elastic plate undergoing point force excitation and radiating into an acoustic cavity. Vibroacoustic modelling using FDTD can be computationally expensive because structure-borne sound wavespeeds are relatively high and a fine spatial resolution is often required. In this paper a scaling approach is proposed and validated to overcome this problem through modifications to the geometry and physical properties. This allows much larger time steps to be used in the model which significantly reduces the computation time. Additional reductions in computation time are achieved by introducing an alternative approach to model the boundaries between the air and the solid media. Experimental validation is carried out using a thin metal plate inside a small reverberant room. The agreement between FDTD and measurements confirms the validity of both approaches as well as the FDTD implementation of a thin plate as a three-dimensional solid that can support multiple wave types. Below the lowest room mode, there are large spatial variations in the sound field within the cavity due to the radiating plate; this indicates the importance of having a validated FDTD model for low-frequency vibroacoustic problems.

AB - The goal of clinical speech analysis is to describe abnormalities in speech production that affect a speaker's intelligibility. Landmark analysis identifies abrupt changes in a speech signal and classifies them according to their acoustic profiles. These acoustic markers, called landmarks, may help describe intelligibility deficits in disordered speech. As a first step toward clinical application of landmark analysis, the present study describes expression of landmarks in normal speech. Results of the study revealed that syllabic, glottal, and burst landmarks consist of 94% of all landmarks, and suggest the effect of gender needs to be considered for the analysis. PMID- 29195421 TI - Noise interference with echo delay discrimination in bat biosonar. AB - Echolocating big brown bats (Eptesicus fuscus) were trained in a two-choice task to discriminate differences in the delay of electronic echoes at 1.7 ms delay (30 cm simulated range). Difference thresholds (~45 MUs) were comparable to previously published results. At selected above-threshold differences (116 and 232 MUs delay), performance was measured in the presence of wideband random noise at increasing amplitudes in 10-dB steps to determine the noise level that prevented discrimination. Performance eventually failed, but the bats increased the amplitude and duration of their broadcasts to compensate for increasing noise, which allowed performance to persist at noise levels about 25 dB higher than without compensation. In the 232-MUs delay discrimination condition, echo signal-to-noise ratio (2E/N0) was 8-10 dB at the noise level that depressed performance to chance. Predicted echo-delay accuracy using big brown bat signals follows the Cramer-Rao bound for signal-to-noise ratios above 15 dB, but worsens below 15 dB due to side-peak ambiguity. At 2E/N0 = 7-10 dB, predicted Cramer-Rao delay accuracy would be about 1 MUs; considering side-peak ambiguity it would be about 200-300 MUs. The bats' 232 MUs performance reflects the intrusion of side peak ambiguity into delay accuracy at low signal-to-noise ratios. PMID- 29195422 TI - A transfer learning approach to goodness of pronunciation based automatic mispronunciation detection. AB - Goodness of pronunciation (GOP) is the most widely used method for automatic mispronunciation detection. In this paper, a transfer learning approach to GOP based mispronunciation detection when applying maximum F1-score criterion (MFC) training to deep neural network (DNN)-hidden Markov model based acoustic models is proposed. Rather than train the whole network using MFC, a DNN is used, whose hidden layers are borrowed from native speech recognition with only the softmax layer trained according to the MFC objective function. As a result, significant mispronunciation detection improvement is obtained. In light of this, the two stage transfer learning based GOP is investigated in depth. The first stage exploits the hidden layer(s) to extract phonetic-discriminating features. The second stage uses a trainable softmax layer to learn the human standard for judgment. The validation is carried out by experimenting with different mispronunciation detection architectures using acoustic models trained by different criteria. It is found that it is preferable to use frame-level cross entropy to train the hidden layer parameters. Classifier based mispronunciation detection is further experimented with using features computed by transfer learning based GOP and it is shown that it also helps to achieve better results. PMID- 29195423 TI - Evaluation of an experimental electrohydraulic discharge device for extracorporeal shock wave lithotripsy: Pressure field of sparker array. AB - In this paper, an extracorporeal shock wave source composed of small ellipsoidal sparker units is described. The sparker units were arranged in an array designed to produce a coherent shock wave of sufficient strength to fracture kidney stones. The objective of this paper was to measure the acoustical output of this array of 18 individual sparker units and compare this array to commercial lithotripters. Representative waveforms acquired with a fiber-optic probe hydrophone at the geometric focus of the sparker array indicated that the sparker array produces a shock wave (P+ ~40-47 MPa, P- ~2.5-5.0 MPa) similar to shock waves produced by a Dornier HM-3 or Dornier Compact S. The sparker array's pressure field map also appeared similar to the measurements from a HM-3 and Compact S. Compared to the HM-3, the electrohydraulic technology of the sparker array produced a more consistent SW pulse (shot-to-shot positive pressure value standard deviation of +/-4.7 MPa vs +/-3.3 MPa). PMID- 29195424 TI - Absorption, scattering, and radiation force efficiencies in the longitudinal wave scattering by a small viscoelastic particle in an isotropic solid. AB - Analytical expressions of the absorption, scattering, and elastic radiation force efficiency factors are derived for the longitudinal plane wave scattering by a small viscoelastic particle in a lossless solid matrix. The particle is assumed to be much smaller than the incident wavelength, i.e., the so-called long wavelength (Rayleigh) approximation. The efficiencies are dimensionless quantities that represent the absorbed and scattering powers and the elastic radiation force on the particle. In the quadrupole approximation, they are expressed in terms of contrast functions (bulk and shear moduli, and density) between the particle and solid matrix. The results for a high-density polyethylene particle embedded in an aluminum matrix agree with those obtained with the partial wave expansion method. Additionally, the connection between the elastic radiation force and forward scattering function is established through the optical theorem. The present results should be useful for ultrasound characterization of particulate composites, and the development of implanted devices activated by radiation force. PMID- 29195426 TI - Acoustic realization of Mandarin neutral tone and tone sandhi in infant-directed speech and Lombard speech. AB - Mandarin lexical tones are modified in both infant-directed speech (IDS) and Lombard speech, resulting in tone hyperarticulation. However, it is unclear if these registers also alter contextual tones (neutral tone and tone sandhi) and if such phonetic modification might affect acquisition of these tones. This study therefore examined how neutral tone and tone sandhi are realized in IDS, and how their acoustic manifestations compare with those in Lombard speech, where the communicative needs of listeners differ. Neutral tone and tone sandhi productions were elicited from 15 Mandarin-speaking mothers during (1) interactions with their 12-month-old infants (IDS), (2) in conversation with a Mandarin-speaking adult in a noisy environment (Lombard speech), and (3) in conversation with a Mandarin-speaking adult in a quiet environment (adult-directed speech). The results showed that, although both contextual tones were modified in IDS and Lombard speech, their key tone features were maintained. In addition, IDS and Lombard speech modified these tones differently: IDS increased pitch height and modified pitch contour, while Lombard speech increased pitch height only. The realization of neutral tone and tone sandhi across registers is discussed with reference to listeners' different communicative needs. PMID- 29195427 TI - Pitch matching in bimodal cochlear implant patients: Effects of frequency, spectral envelope, and level. AB - This study systematically investigated the effects of frequency, level, and spectral envelope on pitch matching in twelve bimodal cochlear implant (CI) users. The participants were asked to vary the frequency and level of a pure or complex tone (adjustable sounds) presented in the non-implanted ear to match the pitch and loudness of different reference stimuli presented to the implanted ear. Three reference sounds were used: single electrode pulse trains, pure tones, and piano notes. The data showed a significant effect of the frequency and complexity of the reference sounds. No significant effect of the level of the reference sounds was found. The magnitude of effect of frequency was compressed in the implanted ear: on average a difference of seven semitones in the non-implanted ear induced the same pitch change as a difference of 19 to 24 semitones for a stimulus presented to the implanted ear. The spectral envelope of the adjustable sound presented to the non-implanted ear also had a significant effect. The matched frequencies were higher by an average of six semitones for the pure tone compared to a complex tone. Overall, the CI listeners might have matched the stimuli based on timbre characteristics such as brightness. PMID- 29195428 TI - Temporal effects in interaural and sequential level difference perception. AB - Temporal effects in interaural level difference (ILD) perception are not well understood. While it is often assumed that ILD sensitivity is independent of the temporal stimulus properties, a reduction of ILD sensitivity for stimuli with a high modulation rate has been reported (known under the term binaural adaptation). Experiment 1 compared ILD thresholds and sequential-level-difference (SLD) thresholds using 300-ms bandpass-filtered pulse trains (centered at 4 kHz) with rates of 100, 400, and 800 pulses per second (pps). In contrast to the SLD thresholds, ILD thresholds were elevated at 800 pps, consistent with literature data that had previously been attributed to binaural adaptation. Experiment 2 showed better ILD sensitivity for pulse trains than for pure tones, suggesting that amplitude modulation enhances ILD sensitivity. The present ILD data and binaural adaptation data from the literature were predicted by a model combining well-established auditory periphery front-ends with an interaural comparison stage. The model also accounted for other published ILD data, including target ILD thresholds in diotic forward and backward fringes and ILD thresholds with different amounts of interaural correlation. Overall, a variety of temporal effects in ILD perception, including binaural adaptation, appear to be largely attributable to monaural peripheral auditory processing. PMID- 29195429 TI - Stochastic sediment property inversion in Shallow Water 06. AB - Received time-series at a short distance from the source allow the identification of distinct paths; four of these are direct, surface and bottom reflections, and sediment reflection. In this work, a Gibbs sampling method is used for the estimation of the arrival times of these paths and the corresponding probability density functions. The arrival times for the first three paths are then employed along with linearization for the estimation of source range and depth, water column depth, and sound speed in the water. Propagating densities of arrival times through the linearized inverse problem, densities are also obtained for the above parameters, providing maximum a posteriori estimates. These estimates are employed to calculate densities and point estimates of sediment sound speed and thickness using a non-linear, grid-based model. Density computation is an important aspect of this work, because those densities express the uncertainty in the inversion for sediment properties. PMID- 29195430 TI - Comparing the effect of aperture extension on the peak sidelobe level of sparse arrays. AB - The reduced number of sensors in sparse arrays create high peak sidelobe levels (PSLs). This letter compares the PSLs of minimum redundancy arrays (MRAs), minimum hole arrays (MHAs), and co-prime sensor arrays (CSAs) (conventionally beamformed and product processed) with fully populated uniform linear arrays (ULAs) as a function of aperture using both numerical simulations and experimental data. This letter finds that PSLs of MRAs, MHAs, and conventionally processed CSAs are much higher than the ULA PSL and are largely insensitive to aperture extension. In contrast, CSA product processing decreases the PSL with increasing aperture, eventually matching the ULA PSL. PMID- 29195431 TI - Two laboratory methods of assessing annoyance due to railway noise and vibration. AB - In laboratory experiments, total annoyance due to combined noise and vibration and partial annoyances due to each source in the presence of the other can be assessed in two ways: during separate sessions dedicated to the evaluation of each kind of annoyance, and during the same session. This letter examines the difference between annoyance responses provided by the two methods. No differences were found between partial (respectively, total) annoyance responses measured during separate sessions and those measured during the same session. The latter procedure allows reducing the number of stimuli to which the participants are subjected. PMID- 29195432 TI - Dynamic temporal behaviour of the keyboard action on the Hammond organ and its perceptual significance. AB - The Hammond organ is one of earliest electronic instruments and is still used widely in contemporary popular music. One of its main sonic features is the "key click," a transient that occurs upon note onset, caused by the mechanical bouncing of the nine electric contacts actuated during each key press. A study of the dynamic mechanical behaviour of the contact bounces is presented, showing that the velocity, the type of touch and, more in general, the temporal evolution of the key position, all affect different characteristics of the contact bounces. A second study focuses on the listener's perception of the generated sound and finds that listeners can classify sounds produced on the Hammond organ according to the type of touch and velocity used. It is concluded that the Hammond organ is a touch-responsive instrument and that the gesture used to produce a note affects the generated sound across multiple dimensions. The control available at the fingertips of the musician is therefore such that it cannot be easily reduced to a single scalar velocity parameter, as is common practice in modern digital emulations of the instrument. PMID- 29195433 TI - Reliability of individual differences in degraded speech perception. AB - Listeners' speech perception abilities vary extensively in challenging listening conditions. There is little evidence as to whether this variability is a result of true, stable individual differences or just variability arising from measurement error. This study examines listeners' word recognition abilities across multiple sessions and a variety of degraded speech tasks (noise-vocoded, time-compressed, and speech in babble noise). Participants transcribed isolated single syllable words presented in all three degradation types and repeated these tasks (with different words) on a separate day. Correlations of transcription accuracy demonstrate that individual differences in performance are reliable across sessions. In addition, performance on all three degradation types was correlated. These results suggest that differences in performance on degraded speech perception tasks for normal hearing listeners are robust and that there are underlying factors that promote the ability to understand degraded speech regardless of the specific manner of degradation. Uncovering these general performance factors may provide insight into the salient performance variance observed in listeners with hearing impairment. PMID- 29195434 TI - Last call: Passive acoustic monitoring shows continued rapid decline of critically endangered vaquita. AB - The vaquita is a critically endangered species of porpoise. It produces echolocation clicks, making it a good candidate for passive acoustic monitoring. A systematic grid of sensors has been deployed for 3 months annually since 2011; results from 2016 are reported here. Statistical models (to compensate for non uniform data loss) show an overall decline in the acoustic detection rate between 2015 and 2016 of 49% (95% credible interval 82% decline to 8% increase), and total decline between 2011 and 2016 of over 90%. Assuming the acoustic detection rate is proportional to population size, approximately 30 vaquita (95% credible interval 8-96) remained in November 2016. PMID- 29195435 TI - Consistent modelling of wind turbine noise propagation from source to receiver. AB - The unsteady nature of wind turbine noise is a major reason for annoyance. The variation of far-field sound pressure levels is not only caused by the continuous change in wind turbine noise source levels but also by the unsteady flow field and the ground characteristics between the turbine and receiver. To take these phenomena into account, a consistent numerical technique that models the sound propagation from the source to receiver is developed. Large eddy simulation with an actuator line technique is employed for the flow modelling and the corresponding flow fields are used to simulate sound generation and propagation. The local blade relative velocity, angle of attack, and turbulence characteristics are input to the sound generation model. Time-dependent blade locations and the velocity between the noise source and receiver are considered within a quasi-3D propagation model. Long-range noise propagation of a 5 MW wind turbine is investigated. Sound pressure level time series evaluated at the source time are studied for varying wind speeds, surface roughness, and ground impedances within a 2000 m radius from the turbine. PMID- 29195436 TI - Band structure analysis of phononic crystals based on the Chebyshev interval method. AB - Due to environmental changes and manufacturing errors, uncertainties inherently exist in phononic crystals, especially in the material properties and geometric parameters. To handle the uncertainties with limited information, two different methods are proposed for band structure analysis of phononic crystals with uncertainties. One is the Monte Carlo method (MCM). The main shortcoming of it is the high computational cost. The other is the simplex Chebyshev polynomial expansion (SPCE) method. In addition, the computational efficiency of the SPCE method is much higher. In the SPCE method, the simplex Chebyshev is employed to estimate the band structures of phononic crystals. Meanwhile, the simplified incremental sampling strategy is introduced for the simplex Chebyshev to retain calculation accuracy and improve computational efficiency simultaneously. In the Chebyshev surrogate model, the samples yielded with the MCM are used to calculate the interval ranges of the band structures in phononic crystals. Three numerical examples, including a two-dimensional (2D) Helmholtz resonator phononic crystal, a 2D solid-solid phononic crystal, and a three-dimensional phononic crystal, are introduced to verify the effectiveness and efficiency of the proposed method. PMID- 29195437 TI - A revised metric for calculating acoustic dispersion applied to stop inventories. AB - Dispersion Theory [DT; Liljencrants and Lindblom (1972). Language 12(1), 839-862] claims that acoustically dispersed vowel inventories should be typologically common. Dispersion is often quantified using triangle area between three mean vowel formant points. This approach is problematic; it ignores distributions, which affect speech perception [Clayards, Tanenhaus, Aslin, and Jacobs (2008). Cognition 108, 804-809]. This letter proposes a revised metric for calculating dispersion which incorporates covariance. As a test case, modeled vocal tract articulatory-acoustic data of stop consonants [Schwartz, Boe, Badin, and Sawallis (2012). J. Phonetics 40, 20-36] are examined. Although the revised metric does not recover DT predictions for stop inventories, it changes results, showing that dispersion results depend on metric choice, which is often overlooked. The metric can be used in any acoustic space to include information about within-category variation when calculating dispersion. PMID- 29195438 TI - L2 voice recognition: The role of speaker-, listener-, and stimulus-related factors. AB - Previous studies examined various factors influencing voice recognition and learning with mixed results. The present study investigates the separate and combined contribution of these various speaker-, stimulus-, and listener-related factors to voice recognition. Dutch listeners, with arguably incomplete phonological and lexical knowledge in the target language, English, learned to recognize the voice of four native English speakers, speaking in English, during four-day training. Training was successful and listeners' accuracy was shown to be influenced by the acoustic characteristics of speakers and the sound composition of the words used in the training, but not by lexical frequency of the words, nor the lexical knowledge of the listeners or their phonological aptitude. Although not conclusive, listeners with a lower working memory capacity seemed to be slower in learning voices than listeners with a higher working memory capacity. The results reveal that speaker-related, listener-related, and stimulus-related factors accumulate in voice recognition, while lexical information turns out not to play a role in successful voice learning and recognition. This implies that voice recognition operates at the prelexical processing level. PMID- 29195439 TI - The spatial coherence of noise fields evoked by continuous source distributions. AB - In this work, analytic expressions for the spatial coherence of noise fields are derived in the modal domain with the aim of providing a sparse representation. For this purpose, the sound field in a region of interest is expressed in terms of a given pressure distribution on a virtual surrounding cylindrical or spherical surface. According to the Huygens-Fresnel principle, the sound pressure on this surface is represented by a continuous distribution of elementary line or point sources, where orthogonal basis functions characterize the spatial properties. To describe spatially windowed pressure distributions with arbitrary angular extensions, orthogonal basis functions of limited angular support are proposed. As special cases, circular and spherical pressure distributions with uncorrelated source modes of equal power are investigated. It is shown that these distributions result, respectively, in cylindrically isotropic and spherically isotropic, i.e., diffuse noise fields. The analytic expressions derived in this work allow for a prediction of the spatial coherence between arbitrary positions within the region of interest, such that no microphones need to be placed at the actual points of interest. Simulation results are presented to validate the derived relations. PMID- 29195440 TI - Ambient noise forecasting with a large acoustic array in a complex shallow water environment. AB - Forecasting ambient noise levels in the ocean can be a useful way of characterizing the detection performance of sonar systems and projecting bounds on performance into the near future. The assertion is that noise forecasting can be improved with a priori knowledge of source positions coupled with the ability to resolve closely separated sources in bearing. One example of such a system is the large aperture research array located at the South Florida Test Facility. Given radar and Automatic Identification System defined source positions and environmental information, transmission loss (TL) is computed from known source positions to the array. Source levels (SLs) of individual ships are then estimated from computed TL and the pre-determined beam response of the array using a non-negative least squares algorithm. Ambient noise forecasts are formed by projecting the estimated SLs along known ship tracks. Ambient noise forecast estimates are compared to measured beam level data and mean-squared error is computed. A mean squared error as low as 3.5 dB is demonstrated in 30 min forecast estimates when compared to ground truth. PMID- 29195441 TI - A time-domain model for seafloor scattering. AB - Bottom scattering is important for a number of underwater applications: it is a source of noise in target detection and a source of information for sediment classification and geoacoustic inversion. While current models can predict the effective interface scattering strength for layered sediments, these models cannot directly compute the ensemble averaged mean-square pressure. A model for bottom scattering due to a point source is introduced which provides a full-wave solution for mean-square scattered pressure as a function of time under first order perturbation theory. Examples of backscatter time series from various types of seafloors will be shown, and the advantages and limitations of this model will be discussed. PMID- 29195442 TI - Sound production patterns of big-clawed snapping shrimp (Alpheus spp.) are influenced by time-of-day and social context. AB - Snapping shrimp are perhaps the most pervasive sources of biological sound in the ocean. The snapping sounds of cryptic shrimp colonies in shallow coastal habitats worldwide create a near-continuous crackling with high spatiotemporal variability, yet the underlying acoustic ecology is not well understood. This study investigated sound production rates and acoustic behavior of snapping shrimp species common in the Western Atlantic Ocean and Gulf of Mexico (Alpheus heterochaelis and Alpheus angulosus). Snap rates were measured in a controlled laboratory setting under natural light, temperature, and substrate conditions for shrimp held individually, in pairs, and in a ten-shrimp mesocosm, to test hypotheses that acoustic activity varies with time-of-day and social context. Spontaneous snapping was observed for 81 out of 84 solitary shrimp monitored. Time-of-day influenced snap output for individuals and same-sex pairs-higher rates occurred during dusk and night, compared to daylight hours, but this pattern was inconsistent for opposite-sex pairs and a mixed-sex group. These laboratory results provide insight into behavioral rhythms that may influence snapping patterns in natural populations, and underscore the limited understanding of a major sound source in marine environments. PMID- 29195443 TI - Sequential dependencies in pitch judgments. AB - Studies that measure pitch discrimination relate a subject's response on each trial to the stimuli presented on that trial, but there is evidence that behavior depends also on earlier stimulation. Here, listeners heard a sequence of tones and reported after each tone whether it was higher or lower in pitch than the previous tone. Frequencies were determined by an adaptive staircase targeting 75% correct, with interleaved tracks to ensure independence between consecutive frequency changes. Responses for this specific task were predicted by a model that took into account the frequency interval on the current trial, as well as the interval and response on the previous trial. This model was superior to simpler models. The dependence on the previous interval was positive (assimilative) for all subjects, consistent with persistence of the sensory trace. The dependence on the previous response was either positive or negative, depending on the subject, consistent with a subject-specific suboptimal response strategy. It is argued that a full stimulus + response model is necessary to account for effects of stimulus history and obtain an accurate estimate of sensory noise. PMID- 29195444 TI - Detection of keyboard vibrations and effects on perceived piano quality. AB - Two experiments were conducted on an upright and a grand piano, both either producing string vibrations or conversely being silent after the initial keypress, while pianists were listening to the feedback from a synthesizer through insulating headphones. In a quality experiment, participants unaware of the silent mode were asked to play freely and then rate the instrument according to a set of attributes and general preference. Participants preferred the vibrating over the silent setup, and preference ratings were associated to auditory attributes of richness and naturalness in the low and middle ranges. Another experiment on the same setup measured the detection of vibrations at the keyboard, while pianists played notes and chords of varying dynamics and duration. Sensitivity to string vibrations was highest in the lowest register and gradually decreased up to note D5. After the percussive transient, the tactile stimuli exhibited spectral peaks of acceleration whose perceptibility was demonstrated by tests conducted in active touch conditions. The two experiments confirm that piano performers perceive vibratory cues of strings mediated by spectral and spatial summations occurring in the Pacinian system in their fingertips, and suggest that such cues play a role in the evaluation of quality of the musical instrument. PMID- 29195445 TI - Cochlear implant simulator with independent representation of the full spiral ganglion. AB - In cochlear implant simulation with vocoders, narrow-band carriers deliver the envelopes from each analysis band to the cochlear positions of the simulated electrodes. However, this approach does not faithfully represent the continuous nature of the spiral ganglion. The proposed "SPIRAL" vocoder simulates current spread by mixing all envelopes across many tonal carriers. SPIRAL demonstrated that the classic finding of reduced speech-intelligibility benefit with additional electrodes could be due to current spread. SPIRAL produced lower speech reception thresholds than an equivalent noise vocoder. These thresholds are stable for between 20 and 160 carriers. PMID- 29195447 TI - Using reciprocity to derive the far field displacements due to buried sources and scatterers. AB - It is shown that elastodynamic reciprocity provides a simpler approach for deriving the far-field displacements due to buried (sub-surface) sources in a half-space, compared with integral transform techniques. The auxiliary fields employed in this approach are the fields associated with the reflection of plane waves of the three possible polarisations, and the required far field can be expressed in terms of these well-known auxiliary fields. The crucial step in this approach is to evaluate a surface integral involving cross-work terms between an outgoing spherical wavefront and the auxiliary fields consisting of incident and reflected plane waves. This integral can be evaluated by the stationary phase approximation for the two-dimensional case, or by a generalisation of this approximation for the three-dimensional case. Although this evaluation involves several distinct contributions, the final result is shown to be very simple, and it can be interpreted as a generalisation of a known result for the one dimensional case, whereby the net contribution arises only from counter propagating waves of the same mode. The results derived for a buried force are extended to the case of buried cracks by exploiting the body force equivalents for displacement discontinuities across a surface. PMID- 29195448 TI - The influence of visual distance on the room-acoustic experience of auralizations. AB - Auralizations have become more prevalent in architectural acoustics and virtual reality. Studies have shown that by employing a methodical calibration procedure, ecologically/perceptually valid auralizations can be obtained. Another study demonstrated a manner to include dynamic voice directivity with results indicating these auralizations were judged significantly more plausible than auralizations with static source orientations. With the increased plausibility of auralizations, it is possible to study room-acoustic experience employing virtual reality, having confidence that the results also apply to real-life situations. Limited studies have examined the influence of visuals on room-acoustic experience. Using a virtual reality framework, this study investigated the influence of visuals on the room-acoustic experience of auralizations. Evaluations compared dynamic voice auralizations coherently matched with visualization positions to incoherently matched audio-visual pairs. Based on the results, the test population could be divided into three subgroups: (1) those who judged auralizations more acoustically distant with increased visual distance, (2) those who judged auralizations louder with increased visual distance, and (3) those whose audio judgment was uninfluenced by the visual stimulus. PMID- 29195446 TI - A common microstructure in behavioral hearing thresholds and stimulus-frequency otoacoustic emissions. AB - Behavioral hearing thresholds and otoacoustic emission (OAE) spectra often exhibit quasiperiodic fluctuations with frequency. For behavioral and OAE responses to single tones-the latter referred to as stimulus-frequency otoacoustic emissions (SFOAEs)-this microstructure has been attributed to intracochlear reflections of SFOAE energy between its region of generation and the middle ear boundary. However, the relationship between behavioral and SFOAE microstructures, as well as their presumed dependence on the properties of the SFOAE-generation mechanism, have yet to be adequately examined. To address this, behavioral thresholds and SFOAEs evoked by near-threshold tones were compared in 12 normal-hearing female subjects. The microstructures observed in thresholds and both SFOAE amplitudes and delays were found to be strikingly similar. SFOAE phase accumulated an integer number of cycles between the frequencies of microstructure maxima, consistent with a dependence of microstructure periodicity on SFOAE propagation delays. Additionally, microstructure depth was correlated with SFOAE magnitude in a manner resembling that predicted by the intracochlear reflection framework, after assuming reasonable values of parameters related to middle ear transmission. Further exploration of this framework may yield more precise estimates of such parameters and provide insight into their frequency dependence.

AB - Machine learning classifiers are shown to outperform conventional matched field processing for a deep water (600 m depth) ocean acoustic-based ship range estimation problem in the Santa Barbara Channel Experiment when limited environmental information is known. Recordings of three different ships of opportunity on a vertical array were used as training and test data for the feed forward neural network and support vector machine classifiers, demonstrating the feasibility of machine learning methods to locate unseen sources. The classifiers perform well up to 10 km range whereas the conventional matched field processing fails at about 4 km range without accurate environmental information. PMID- 29195450 TI - Generation of 1/f noise from a broken-symmetry model for the arbitrary absolute pitch of musical melodies. AB - A model is presented to generate power spectrum noise with intensity proportional to 1/f as a function of frequency f. The model arises from a broken-symmetry variable, which corresponds to absolute pitch, where fluctuations occur in an attempt to restore that symmetry, influenced by interactions in the creation of musical melodies. PMID- 29195451 TI - Why orchestral musicians are bound to wear earplugs: About the ineffectiveness of physical measures to reduce sound exposure. AB - Symphony orchestra musicians are exposed to noise levels that put them at risk of developing hearing damage. This study evaluates the potential effectivity of common control measures used in orchestras on open stages with a typical symphonic setup. A validated acoustic prediction model is used that calculates binaural sound exposure levels at the ears of all musicians in the orchestra. The model calculates the equivalent sound levels for a performance of the first 2 min of the 4th movement of Mahler's 1st symphony, which can be considered representative for loud orchestral music. Calculated results indicate that risers, available space, and screens at typical positions do not significantly influence sound exposure. A hypothetical scenario with surround screens shows that, even when shielding all direct sound from others, sound exposure is reduced moderately with the largest effect on players in loud sections. In contrast, a dramatic change in room acoustic conditions only leads to considerable reductions for soft players. It can be concluded that significant reductions are only reached with extreme measures that are unrealistic. It seems impossible for the studied physical measures to be effective enough to replace hearing protection devices such as ear plugs. PMID- 29195452 TI - Evaluation and calibration of mobile phones for noise monitoring application. AB - The increasing number and quality of sensors integrated in mobile phones have paved the way for sensing schemes driven by city dwellers. The sensing quality can drastically depend on the mobile phone, and appropriate calibration strategies are needed. This paper evaluates the quality of noise measurements acquired by a variety of Android phones. The Ambiciti application was developed so as to acquire a larger control over the acquisition process. Pink and narrowband noises were used to evaluate the phones' accuracy at levels ranging from background noise to 90 dB(A) inside the lab. Conclusions of this evaluation lead to the proposition of a calibration strategy that has been embedded in Ambiciti and applied to more than 50 devices during public events. A performance analysis addressed the range, accuracy, precision, and reproducibility of measurements. After identification and removal of a bias, the measurement error standard deviation is below 1.2 dB(A) within a wide range of noise levels [45 to 75 dB(A)], for 12 out of 15 phones calibrated in the lab. In the perspective of citizens-driven noise sensing, in situ experiments were carried out, while additional tests helped to produce recommendations regarding the sensing context (grip, orientation, moving speed, mitigation, frictions, wind). PMID- 29195453 TI - A hybrid phononic crystal for roof application. AB - Phononic crystal is a type of acoustic material, and the study of phononic crystals has attracted great attention from national research institutions. Meanwhile, noise reduction in the low-frequency range has always encountered difficulties and troubles in the engineering field. In order to obtain a unique and effective low-frequency noise reduction method, in this paper a low frequency noise attenuation system based on phononic crystal structure is proposed and demonstrated. The finite element simulation of the band gap is consistent with the final test results. The effects of structure parameters on the band gaps were studied by changing the structure parameters and the band gaps can be controlled by suitably tuning structure parameters. The structure and results provide a good support for phononic crystal structures engineering application. PMID- 29195454 TI - Broadband ship noise and its potential impacts on Indo-Pacific humpback dolphins: Implications for conservation and management. AB - Ship noise pollution has raised considerable concerns among regulatory agencies and cetacean researchers worldwide. There is an urgent need to quantify ship noise in coastal areas and assess its potential biological impacts. In this study, underwater broadband noise from commercial ships in a critical habitat of Indo-Pacific humpback dolphins was recorded and analyzed. Data analysis indicated that the ship noise caused by the investigated commercial ships with an average length of 134 +/- 81 m, traveling at 18.8 +/- 2.5 km/h [mean +/- standard deviation (SD), n = 21] comprises mid-to-high components with frequencies approaching and exceeding 100 kHz, and the ship noise could be sensed auditorily by Indo-Pacific humpback dolphins within most of their sensitive frequency range. The contributions of ship noise to ambient noise were highest in two third-octave bands with center frequencies of 8 and 50 kHz, which are within the sensitive hearing range of Indo-Pacific humpback dolphins and overlap the frequency of sounds that are biologically significant to the dolphins. It is estimated that ship noise in these third-octave bands can be auditorily sensed by and potentially affect the dolphins within 2290 +/- 1172 m and 848 +/- 358 m (mean +/ SD, n = 21), respectively. PMID- 29195455 TI - Ontogeny of individual and litter identity signaling in grunts of piglets. AB - Many studies have shown that animal vocalizations can signal individual identity and group/family membership. However, much less is known about the ontogeny of identity information-when and how this individual/group distinctiveness in vocalizations arises and how it changes during the animal's life. Recent findings suggest that even species that were thought to have limited vocal plasticity could adjust their calls to sound more similar to each other within a group. It has already been shown that sows can acoustically distinguish their own offspring from alien piglets and that litters differ in their calls. Surprisingly, individual identity in piglet calls has not been reported yet. In this paper, this gap is filled, and it is shown that there is information about piglet identity. Information about litter identity is confirmed as well. Individual identity increased with age, but litter vocal identity did not increase with age. The results were robust as a similar pattern was apparent in two situations differing in arousal: isolation and back-test. This paper argues that, in piglets, increased individual discrimination results from the rapid growth of piglets, which is likely to be associated with growth and diversification of the vocal tract rather than from social effects and vocal plasticity. PMID- 29195456 TI - Monitoring ice thickness and elastic properties from the measurement of leaky guided waves: A laboratory experiment. AB - The decline of Arctic sea ice extent is one of the most spectacular signatures of global warming, and studies converge to show that this decline has been accelerating over the last four decades, with a rate that is not reproduced by climate models. To improve these models, relying on comprehensive and accurate field data is essential. While sea ice extent and concentration are accurately monitored from microwave imagery, an accurate measure of its thickness is still lacking. Moreover, measuring observables related to the mechanical behavior of the ice (such as Young's modulus, Poisson's ratio, etc.) could provide better insights in the understanding of sea ice decline, by completing current knowledge so far acquired mostly from radar and sonar data. This paper aims at demonstrating on the laboratory scale that these can all be estimated simultaneously by measuring seismic waves guided in the ice layer. The experiment consisted of leaving a water tank in a cold room in order to grow an ice layer at its surface. While its thickness was increasing, ultrasonic guided waves were generated with a piezoelectric source, and measurements were subsequently inverted to infer the thickness and mechanical properties of the ice with very good accuracy. PMID- 29195457 TI - Cylindrical heat conduction and structural acoustic models for enclosed fiber array thermophones. AB - Calculation of the heat loss for thermophone heating elements is a function of their geometry and the thermodynamics of their surroundings. Steady-state behavior is difficult to establish or evaluate as heat is only flowing in one direction in the device. However, for a heating element made from an array of carbon fibers in a planar enclosure, several assumptions can be made, leading to simple solutions of the heat equation. These solutions can be used to more carefully determine the efficiency of thermophones of this geometry. Acoustic response is predicted with the application of a Helmholtz resonator and thin plate structural acoustics models. A laboratory thermophone utilizing a sparse horizontal array of fine (6.7 MUm diameter) carbon fibers is designed and tested. Experimental results are compared with the model. The model is also used to examine the optimal array density for maximal efficiency. PMID- 29195458 TI - Predicting effects of hearing-instrument signal processing on consonant perception. AB - This study investigated the influence of hearing-aid (HA) and cochlear-implant (CI) processing on consonant perception in normal-hearing (NH) listeners. Measured data were compared to predictions obtained with a speech perception model [Zaar and Dau (2017). J. Acoust. Soc. Am. 141, 1051-1064] that combines an auditory processing front end with a correlation-based template-matching back end. In terms of HA processing, effects of strong nonlinear frequency compression and impulse-noise suppression were measured in 10 NH listeners using consonant vowel stimuli. Regarding CI processing, the consonant perception data from DiNino et al. [(2016). J. Acoust. Soc. Am. 140, 4404-4418] were considered, which were obtained with noise-vocoded vowel-consonant-vowel stimuli in 12 NH listeners. The inputs to the model were the same stimuli as were used in the corresponding experiments. The model predictions obtained for the two data sets showed a large agreement with the perceptual data both in terms of consonant recognition and confusions, demonstrating the model's sensitivity to supra-threshold effects of hearing-instrument signal processing on consonant perception. The results could be useful for the evaluation of hearing-instrument processing strategies, particularly when combined with simulations of individual hearing impairment. PMID- 29195459 TI - Subcortical amplitude modulation encoding deficits suggest evidence of cochlear synaptopathy in normal-hearing 18-19 year olds with higher lifetime noise exposure. AB - Noise exposure and aging can damage cochlear synapses required for suprathreshold listening, even when cochlear structures needed for hearing at threshold remain unaffected. To control for effects of aging, behavioral amplitude modulation (AM) detection and subcortical envelope following responses (EFRs) to AM tones in 25 age-restricted (18-19 years) participants with normal thresholds, but different self-reported noise exposure histories were studied. Participants with more noise exposure had smaller EFRs and tended to have poorer AM detection than less exposed individuals. Simulations of the EFR using a well-established cochlear model were consistent with more synaptopathy in participants reporting greater noise exposure. PMID- 29195460 TI - Multilevel modeling and regression of community annoyance to transportation noise. AB - A multilevel (hierarchical) model is devised that separates noise tolerance into variations occurring at the levels of individual listeners and communities. This approach successfully describes the characteristics of real community transportation noise surveys, with the individual- and community-level variations producing distinct statistical signatures, both of which are evident in the surveys. Predictions are provided for quantities such as the probability of annoyance based on the observed noise level and statistical parameters characterizing the community tolerance. Regression analyses are performed using a multilevel, generalized linear model, which provides an appropriate generalization encompassing both no pooling (separate community-by-community analysis) and full pooling (all communities together) of survey data, and enables noise tolerances and their variations at the individual and community levels to be distinguished and quantified. Variations in individual tolerance and sound exposure within communities are found to be larger than variations in tolerance between communities; however, the variations between communities are still significant and observable. Analysis of multiple types of transportation noise with the multilevel model indicates that tolerance is highest for railway noise with low vibrations, followed by roadway noise, airport noise, and railway noise with high vibrations, as consistent with previous studies. PMID- 29195461 TI - Using the trapped energy ratio for source depth discrimination with a horizontal line array: Theory and experimental results. AB - The problem of acoustic source depth discrimination was introduced as a way to get basic information on source depth in configurations where accurate depth estimation is not feasible. It is a binary classification problem, aiming to evaluate whether the source is near the surface or submerged. Herein, the classification relies on a signal measured with a horizontal line array in shallow water. Knowing the source-array distance is not required but the source bearing has to be close to the array endfire. Signal processing relies on a normal-mode propagation model, and thus requires prior knowledge of the mode characteristics. The decision relies on an estimation of the trapped energy ratio in mode space. The performance is predicted with simulations and Monte Carlo methods, allowing one to compare several estimators based on different mode filters, and to choose an appropriate decision threshold. The impact on performance of frequency, noise level, horizontal aperture, and environmental mismatch is numerically studied. Finally, the approach is validated on experimental data acquired with a horizontal line array deployed off the coast of New Jersey, and the impact of errors in the environmental model is illustrated. The investigated approach successfully identifies a surface ship and a submerged towed source. PMID- 29195462 TI - Cross-beam coherence of infrasonic signals at local and regional ranges. AB - Signals collected by infrasound arrays require continuous analysis by skilled personnel or by automatic algorithms in order to extract useable information. Typical pieces of information gained by analysis of infrasonic signals collected by multiple sensor arrays are arrival time, line of bearing, amplitude, and duration. These can all be used, often with significant accuracy, to locate sources. A very important part of this chain is associating collected signals across multiple arrays. Here, a pairwise, cross-beam coherence method of signal association is described that allows rapid signal association for high signal-to noise ratio events captured by multiple infrasound arrays at ranges exceeding 150 km. Methods, test cases, and results are described. PMID- 29195463 TI - ACOUSTICAL STANDARDS NEWS.

PMID- 29195464 TI - Wind noise spectra in small Reynolds number turbulent flows. AB - Wind noise spectra caused by wind from fans in indoor environments have been found to be different from those measured in outdoor atmospheric conditions. Although many models have been developed to predict outdoor wind noise spectra under the assumption of large Reynolds number [Zhao, Cheng, Qiu, Burnett, and Liu (2016). J. Acoust. Soc. Am. 140, 4178-4182, and the references therein], they cannot be applied directly to the indoor situations because the Reynolds number of wind from fans in indoor environments is usually much smaller than that experienced in atmospheric turbulence. This paper proposes a pressure structure function model that combines the energy-containing and dissipation ranges so that the pressure spectrum for small Reynolds number turbulent flows can be calculated. The proposed pressure structure function model is validated with the experimental results in the literature, and then the obtained pressure spectrum is verified with the numerical simulation and experiment results. It is demonstrated that the pressure spectrum obtained from the proposed pressure structure function model can be utilized to estimate wind noise spectra caused by turbulent flows with small Reynolds numbers. PMID- 29195465 TI - Extracting the time domain Green's function from ocean ambient noise using acoustic vector sensors. AB - A function that closely resembles the two-point time-domain Green's function (TDGF) representing the time delays associated with multipath between the two sensors can be recovered by correlating the noise field measured by two sensors. Here, a technique for extracting the TDGF from ambient ocean noise using acoustic vector sensors is presented. Experimental results suggest that the averaging time to extract TDGF is greatly reduced if sound pressure sensors (hydrophones) are replaced by acoustic vector sensors. The direct arrival and bottom bounce arrival were extracted successfully with only 1 min of vertical velocity data, while the bottom bounce arrival was not extracted with even 10 min of sound pressure data. PMID- 29195466 TI - Doppler spectra of airborne ultrasound forward scattered by the rough surface of open channel turbulent water flows. AB - Experimental data are presented on the Doppler spectra of airborne ultrasound forward scattered by the rough dynamic surface of an open channel turbulent flow. The data are numerically interpreted based on a Kirchhoff approximation for a stationary random water surface roughness. The results show a clear link between the Doppler spectra and the characteristic spatial and temporal scales of the water surface. The decay of the Doppler spectra is proportional to the velocity of the flow near the surface. At higher Doppler frequencies the measurements show a less steep decrease of the Doppler spectra with the frequency compared to the numerical simulations. A semi-empirical equation for the spectrum of the surface elevation in open channel turbulent flows over a rough bed is provided. The results of this study suggest that the dynamic surface of open channel turbulent flows can be characterized remotely based on the Doppler spectra of forward scattered airborne ultrasound. The method does not require any equipment to be submerged in the flow and works remotely with a very high signal to noise ratio. PMID- 29195467 TI - Characterization of gain and directivity of exponential horn receivers. AB - It is difficult and expensive to match the sensitivity of the most sensitive vertebrate ears with off-the-shelf microphones due to the self-noise of the sensor. The extremely small apertures of microelectromechanical microphones create options to use horn waveguides to amplify sound prior to transduction without resulting in an unacceptably narrow directivity. Substantial gain can be achieved at wavelengths larger than the horn. An analytical model of an exponential horn embedded in a rigid spherical housing was formulated to describe the gain relative to a free-field receiver as a function of frequency and angle of arrival. For waves incident on-axis, the analytical model provided an accurate estimate of gain at high frequencies as validated by experimental measurement. Numerical models, using the equivalent source method, can account for higher order modes and comprehensively describe the acoustic scattering within and around the horn for waves arriving from any direction. Results show the directivity of horn receivers were adequately described by the analytical model up to a critical wavelength, and the mechanisms of deviation in gain at high frequencies and large angles of arrival were identified. PMID- 29195468 TI - Incorporating evanescent modes and flow losses into reference impedances in acoustic Thevenin calibration. AB - This paper proposes an alternative approach to acoustic Thevenin calibration of an ear probe. An existing methodology derives the Thevenin-equivalent source parameters from the measured probe pressures in a number of short waveguides by solving an overdetermined system of equations. This existing methodology is affected by errors caused by evanescent modes when the waveguide model lengths are estimated. These errors introduce a parallel acoustic compliance into the source parameters. The proposed methodology takes into account evanescent modes and flow losses in the transition between the probe tube and waveguides during calibration. This is achieved by positioning the probe tube, without an ear tip, flush with the input plane in waveguides of well-defined dimensions and utilizing the physical rather than estimated lengths to calculate the analytical waveguide models. Terms that model evanescent modes and flow losses are added to the plane wave impedance and adjusted to minimize the calibration error. It is shown that this method can reduce the calibration error across a wide frequency range and remove the parallel compliance from the source parameters. This approach leads to an independence of the source parameters on the calibration waveguide radius, though subsequent impedance measurements are still affected by evanescent modes. PMID- 29195469 TI - Comparison of a target-equalization-cancellation approach and a localization approach to source separation. AB - Interaural differences are important for listeners to be able to maintain focus on a sound source of interest in the presence of multiple sources. Because interaural differences are sound localization cues, most binaural-cue-based source separation algorithms attempt separation by localizing each time-frequency (T-F) unit to one of the possible source directions using interaural differences. By assembling T-F units that are assigned to one direction, the sound stream from that direction is enhanced. In this paper, a different type of binaural cue for source-separation purposes is proposed. For each T-F unit, the target-direction signal is cancelled by applying the equalization-cancellation (EC) operation to cancel the signal from the target direction; then, the dominance of the target in each T-F unit is determined by the effectiveness of the cancellation. Specifically, the energy change from cancellation is used as the criterion for target dominance for each T-F unit. Source-separation performance using the target-EC cue is compared with performance using localization cues. With simulated multi-talker and diffuse-babble interferers, the algorithm based on target-EC cues yields better source-separation performance than the algorithm based on localization cues, both in direct comparison with the ideal binary mask and in measured speech intelligibility for the separated target streams. PMID- 29195470 TI - Acoustic occurrence detection of a newly recorded Indo-Pacific humpback dolphin population in waters southwest of Hainan Island, China. AB - In 2014, Indo-Pacific humpback dolphins were recorded for the first time in waters southwest of Hainan Island, China. In this paper, the temporal occurrence of Indo-Pacific humpback dolphins in this region was detected by stationary passive acoustic monitoring. During the 130-day observation period (from January to July 2016), 1969 click trains produced by Indo-Pacific humpback dolphins were identified, and 262 ten-minute recording bins contained echolocation click trains of dolphins, of which 70.9% were at night and 29.1% were during the day. A diurnal rhythm with a nighttime peak in acoustic detections was found. Passive acoustic detections indicated that the Indo-Pacific humpback dolphins frequently occurred in this area and were detected mainly at night. This information may be relevant to conservation efforts for these dolphins in the near future. PMID- 29195471 TI - Analysis of the transient surface wave propagation in soft-solid elastic plates. AB - In dynamic elastography, the goal is to estimate the Young's modulus from audio frequency wave propagation in soft-tissues. Within this frequency range, the shear wavelength is centimeter-sized while the compressional wavelength is meter sized. Thus, the experimental data are usually collected in the near-field of the source. Near-field effects have been widely studied for bulk wave propagation. However, the near- and transient-fields of surface and guided waves have received less attention. In this work, the transient surface displacement field in soft solid elastic plates in vacuum is analyzed. Due to the high Poisson's ratio, mode conversion has special characteristics in soft-solids. They are analyzed through this work where it is shown that the transient-field over the surface can be interpreted by tracing a few reflections. The authors show the existence of a critical distance needed for the formation of Rayleigh-Lamb modes. Below this distance, only direct surface waves propagate without contribution from reflected waves. Thus, the dispersion curve differs from that predicted by Rayleigh-Lamb modes. Instead, the authors propose a model based on the interference of surface waves, which agree with the experimental data. In addition, the conditions needed in order to retrieve the shear wave phase velocity from the surface field are given. PMID- 29195472 TI - Simulating alveolar trills using a two-mass model of the tongue tip. AB - This paper investigates the possibility of reproducing the self-sustained oscillation of the tongue tip in alveolar trills. The interest is to study the articulatory and phonatory configurations that are required to produce alveolar trills. Using a realistic geometry of the vocal tract, derived from cineMRI data of a real speaker, the paper studies the mechanical behavior of a lumped two-mass model of the tongue tip. Then, the paper proposes a solution to simulate the incomplete occlusion of the vocal tract during linguopalatal contacts by adding a lateral acoustic waveguide. Finally, the simulation framework is used to study the impact of a set of parameters on the characteristic features of the produced alveolar trills. It shows that the production of trills is favored when the distance between the equilibrium position of the tongue tip and the hard palate in the alveolar zone is less than 1 mm, but without linguopalatal contact, and when the glottis is fully adducted. PMID- 29195473 TI - Clustering dynamics of microbubbles exposed to low-pressure 1-MHz ultrasound. AB - Ultrasound-driven microbubbles have been used in therapeutic applications to deliver drugs across capillaries and into cells or to dissolve blood clots. Yet the performance and safety of these applications have been difficult to control. Microbubbles exposed to ultrasound not only volumetrically oscillate, but also move due to acoustic radiation, or Bjerknes, forces. The purpose of this work was to understand the extent to which microbubbles moved and clustered due to secondary Bjerknes forces. A microbubble population was exposed to a 1-MHz ultrasound pulse with a peak-rarefactional pressure of 50-100 kPa and a pulse length of 20 ms. Microbubbles exposed to low-pressure therapeutic ultrasound were observed to cluster at clustering rates of 0.01-0.02 microbubbles per duration (in ms) per initial average inter-bubble distance (in MUm), resulting in 1 to 3 clustered microbubbles per initial average inter-bubble distance (in MUm). Higher pressures caused faster clustering rates and a larger number of clustered microbubbles. Experimental data revealed clustering time scales, cluster localizations, and cluster sizes that were in reasonable agreement with simulations using a time-averaged model at low pressures. This study demonstrates that clustering of microbubbles occurs within a few milliseconds and is likely to influence the distribution of stimuli produced in therapeutic applications. PMID- 29195474 TI - Optimal bounds for attenuation of elastic waves in porous fluid-saturated media. AB - Explicit expressions for bounds on the effective bulk and shear moduli of mixture of an elastic solid and Newtonian fluid are derived. Since in frequency domain the shear modulus of the Newtonian fluid is complex valued, the effective mixture moduli are, in general, also complex valued and, hence, the bounds are curves in the complex plane. From the general expressions for bounds of effective moduli of viscoelastic mixtures, it is shown that effective bulk and shear moduli of such mixtures must lie between the real axis and a semicircle in the upper half-plane connecting formal lower and upper Hashin-Shtrikman bounds of the mixture of the solid and inviscid fluid of the same compressibility as the Newtonian fluid. Furthermore, it is shown that the bounds on the effective complex bulk and shear moduli of the mixture are optimal; that is, the moduli corresponding to any point on the bounding curves can be attained by the Hashin sphere assemblage penetrated by a random distribution of thin cracks. The results are applicable to a variety of solid/fluid mixtures such as fluid-saturated porous materials and particle suspensions. PMID- 29195475 TI - Measurement of acoustic properties for passive-material samples using multichannel inverse filter. AB - The measurement of acoustic properties for passive-material samples is strongly interfered by reverberations in a limited space. A multichannel inverse filter (MIF) can achieve spatio-temporal focusing by retransmitting the optimal signal estimated from multichannel impulse responses of the transmitter channel and the underwater acoustic channel. To decrease the influence of reverberations on measurements and improve the measurement precision, a MIF is employed to measure the echo reduction and insertion loss, respectively. The method is demonstrated by simulations and experiments, which were performed in a cylindrical tank to measure the two acoustic parameters for a steel plate sample. PMID- 29195476 TI - Scattering of flexural waves from an N-beam resonator in a thin plate. AB - The impedance matrix method is applied to study the scattering of flexural waves propagating in an infinite thin plate containing an N-beam resonator. The resonator consists of a circular hole containing a smaller plate connected to the background plate by a number N of rectangular beams. After representing the boundary conditions in a modal multipole expansion form, a compact expression is obtained for the T-matrix, which relates the incident and the scattered transverse (out-of-plane) waves. The analysis of the scattering cross-section reveals interesting scattering features, like resonances and anisotropy, associated to this type of resonators. Numerical experiments performed within the framework of the finite element method support the accuracy of the model here developed. PMID- 29195477 TI - Ultrawide band gaps in beams with double-leaf acoustic black hole indentations. AB - Band gaps in conventional phononic crystals (PCs) are attractive for applications such as vibration control, wave manipulation, and sound absorption. Their practical implementations, however, are hampered by several factors, among which the large number of cells required and their impractically large size to ensure the stopbands at reasonably low frequencies are on the top of the list. This paper reports a type of beam carved inside with two double-leaf acoustic black hole indentations. By incorporating the local resonance effect and the Bragg scattering effect generated by a strengthening stud connecting the two branches of the indentations, ultrawide band gaps are achieved. Increasing the length of the stud or reducing the residual thickness of the indentation allows the tuning of the band gaps to significantly enlarge the band gaps, which can exceed 90% of the entire frequency range of interest. Experimental results show that with only three cells, the proposed beam allows considerable vibration energy attenuation within an ultra-broad frequency range including the low frequency range, which conventional PCs can hardly reach. Meanwhile, the proposed configuration also enhances the structural integrity, thus pointing at promising applications in vibration control and a high performance wave filter design. PMID- 29195478 TI - Wave characteristics of a cylinder with periodic ribs. AB - This paper deals with wave characteristics of a cylinder with periodic ribs. The equation of motion of the stiffened cylinder is first derived using a receptance coupling method. The dispersion diagrams of the stiffened cylinder are then obtained in order to figure out the effects of the ribs on the wave propagation. Due to the effect of the ribs, the dispersion curves are found to be repeated along the axis of the wavenumber with the repetition period of 2pi/d, where d is the rib distance. Also, dispersion curves are found to show a pass and stop band of the waves. The stop bands appeared at the wavenumber of half of the wavenumber periodicity. The stop band becomes wider as the increase of the circumferential order. The waves in the pass bands are propagating well through the ribs without decay. In contrast, the waves in the stop bands are not propagating, but decaying the magnitudes. The decay of the responses in the stop band increases as the circumferential order increase. The change of the rib stiffness causes the cut-on frequency to change and the modal order to jumble. The change of the rib stiffness also leads to generate a wave whose phase velocity is positive, while group velocity is negative. PMID- 29195479 TI - Level-weighted averaging in elevation to synchronous amplitude-modulated sounds. AB - To program a goal-directed response in the presence of multiple sounds, the audiomotor system should separate the sound sources. The authors examined whether the brain can segregate synchronous broadband sounds in the midsagittal plane, using amplitude modulations as an acoustic discrimination cue. To succeed in this task, the brain has to use pinna-induced spectral-shape cues and temporal envelope information. The authors tested spatial segregation performance in the midsagittal plane in two paradigms in which human listeners were required to localize, or distinguish, a target amplitude-modulated broadband sound when a non modulated broadband distractor was played simultaneously at another location. The level difference between the amplitude-modulated and distractor stimuli was systematically varied, as well as the modulation frequency of the target sound. The authors found that participants were unable to segregate, or localize, the synchronous sounds. Instead, they invariably responded toward a level-weighted average of both sound locations, irrespective of the modulation frequency. An increased variance in the response distributions for double sounds of equal level was also observed, which cannot be accounted for by a segregation model, or by a probabilistic averaging model.

AB - The scattering of a longitudinal Bessel beam of arbitrary order by a sphere embedded in an isotropic solid matrix is theoretically analyzed. The spherical inclusion can be made of a viscoelastic, elastic, or fluid-filled isotropic material. In the analysis, the absorbing, scattering, and extinction efficiency factors are obtained, e.g., the corresponding power per characteristic beam intensity per sphere's cross-section area. Furthermore, the extended optical theorem, which expresses the extinction efficiency in terms of an integral of the longitudinal scattering function is derived. Several features of zeroth- and first-order Bessel beams scattering in solids are illustrated considering a polymer adhesive (cured) sphere embedded in a stainless steel matrix. For instance, omnidirectional scattering can be achieved by choosing specific values of the half-cone angle of the Bessel beam, which is the beam's geometrical parameter. Additionally, it is demonstrated that mode suppression leads to lower absorption inside the inclusion when compared to plane wave scattering results.

AB - In this study the description of underwater vocal repertoire of bearded seal in Svalbard (Norway) was extended. Two autonomous passive acoustic recorders were deployed for one year (August 2014-July 2015) in the inner and outer parts of the Kongsfjorden, and 1728 h were recorded and 17 220 vocalizations were found. Nine different vocalization classes were identified and characterized using ten acoustic parameters. The calls showed heterogeneous spectral features, but share the descending trend of frequency modulation. The different classes emerged were discriminated primarily by bandwidth and duration, and then by minimum frequency, central frequency, and maximum frequency in this order. This study represents a step forward to improve the understanding of the acoustic behaviour and the social function of these calls, and identified long passive acoustic monitoring as an effective method to assess vocal complexity and the ecology of marine species producing sounds. PMID- 29195483 TI - Temporal characteristics of contextual effects in sound localization. AB - Two experiments examined plasticity induced by context in a simple target localization task. The context was represented by interleaved localization trials with the target preceded by a distractor. In a previous study, the context induced large response shifts when the target and distractor stimuli were identical 2-ms-noise clicks [Kopco, Best, and Shinn-Cunningham (2007). J. Acoust. Soc. Am. 121, 420-432]. Here, the temporal characteristics of the contextual effect were examined for the same stimuli. Experiment 1 manipulated the context presentation rate and the distractor-target inter-stimulus interval (ISI). Experiment 2 manipulated the temporal structure of the context stimulus, replacing the one-click distractor either by a distractor consisting of eight sequentially presented clicks or by a noise burst with total energy and duration identical to the eight-click distractor. In experiment 1, the contextual shift size increased with increasing context rate while being largely independent of ISI. In experiment 2, the eight-click-distractor induced a stronger shift than the one-click-distractor context, while the noise-distractor context induced a very small shift. These results suggest that contextual plasticity is an adaptation driven both by low-level factors like spatiotemporal context distribution and higher-level factors like perceptual similarity between the stimuli, possibly related to precedence buildup.

AB - An anatomically based three-dimensional finite-element human middle-ear (ME) model is used to test the sensitivity of ME sound transmission to tympanic membrane (TM) material properties. The baseline properties produce responses comparable to published measurements of ear-canal input impedance and power reflectance, stapes velocity normalized by ear-canal pressure (PEC), and middle ear pressure gain (MEG), i.e., cochlear-vestibule pressure (PV) normalized by PEC. The mass, Young's modulus (ETM), and shear modulus (GTM) of the TM are varied, independently and in combination, over a wide range of values, with soft and bony TM-annulus boundary conditions. MEG is recomputed and plotted for each case, along with summaries of the magnitude and group-delay deviations from the baseline over low (below 0.75 kHz), mid (0.75-5 kHz), and high (above 5 kHz) frequencies. The MEG magnitude varies inversely with increasing TM mass at high frequencies. Increasing ETM boosts high frequencies and attenuates low and mid frequencies, especially with a bony TM annulus and when GTM varies in proportion to ETM, as for an isotropic material. Increasing GTM on its own attenuates low and mid frequencies and boosts high frequencies. The sensitivity of MEG to TM material properties has implications for model development and the interpretation of experimental observations.

AB - Scavenger receptor class B type 1 (SR-B1) is over-expressed in tumour cells where it mediates the uptake of drug payload of reconstituted high density lipoprotein (rHDL) via the process of reverse cholesterol transport. In this study, rHDL was prepared to determine its function as a drug delivery carrier for targeting hepatocellular carcinoma by incorporating the anti-tumour drug garcinia glycosides (GG) into rHDL to yield rHDL/GG nano-complexes. Structural analysis indicated that the rHDL/GG nano-complex was similar to HDL in size. HepG2 cells treated with fluorescent-labelled rHDL/GG exhibited a time-dependent increase in cell death. Further experiment in which HepG2 cells were treated with rHDL/GG plus plasma-derived HDL showed reduction in cell death compared to treatment with rHDL/GG alone, suggesting that plasma-derived HDL compete with rHDL/GG for binding to the SR-B1 on the cell. We concluded that rHDL could not only incorporate GG but could also serve as a carrier, targeting the drug to HepG2 cells via SR-B1.

PMID- 29195486 TI - A safety review of the medications used to treat atopic dermatitis. AB - INTRODUCTION: Atopic dermatitis (AD) is a common disease in children and adults which causes severe physical discomfort and psychosocial distress. Recently novel therapies for AD have been FDA approved for use which creates the need to review the safety surrounding current FDA approved AD medications. Areas covered: Published clinical studies involving topical and oral FDA approved medications for AD are included in this review. Authors used PubMed research database to search for clinical trials involving AD patients. Expert opinion: AD is a common disease which currently has limited FDA approved medications. Given the chronicity of this disease, medications are needed which control disease while minimizing side effects to allow for long term use. Newer approved medications show promise but safety data is limited given their relatively new utilization for AD. PMID- 29195487 TI - Efficacy of levomilnacipran extended release in treating major depressive disorder. AB - INTRODUCTION: Major depressive disorder (MDD) is the leading cause of disability worldwide with a heterogeneous symptom profile. Levomilnacipran extended release (ER) (Fetzima), a SNRI, has been approved by the Food and Drug Administration for treatment of MDD. While categorized as a SNRI, in contradistinction to other approved SNRIs, levomilnacipran exhibits differential affinity for the norepinephrine reuptake transporter when compared to the serotonin reuptake transporter. Areas covered: Completed clinical trials which focused on levomilnacipran ER administered in those with MDD were included in this drug evaluation. Expert opinion: Levomilnacipran ER, like all other first-line antidepressants exhibits significant efficacy in reducing total symptom severity. Levomilnacipran ER is particularly effective at improving measures of motivation, energy, and interest. Head to head comparative trials are not available with other antidepressants, and consequently, there are no claims of superior efficacy when compared to alternative antidepressants. Notwithstanding, it would be a viable and testable hypothesis that differential efficacy in favor of levomilnacipran may be obtained across select dimensions of depressive symptoms (e.g., fatigue and lack of motivation). Unfortunately, rigorous studies evaluating levomilnacipran for cognitive function in MDD have not been conducted. Levomilnacipran ER is generally well tolerated with minimal propensity for metabolic and weight disturbance. PMID- 29195488 TI - Improving the attrition rate of Lanthipeptide discovery for commercial applications. AB - INTRODUCTION: Lanthipeptides are a class of ribosomally synthesized and post translationally modified peptides. Lanthipeptides with antimicrobial activity are referred to as lantibiotics. Lantibiotics are generally active against Gram positive bacteria. However, some modifications have expanded their activity toward Gram-negative bacteria. Furthermore, additional functions aside from antibacterial activities have been reported for lanthipeptides. Areas covered: This review provides a synopsis of current anthipeptide research for potential therapeutics. The review highlights the current tools used for identifying lanthipeptides from genomic sequencing data. It also describes the current approaches that have been used to overcome the limitations in the purification and isolation of lanthipeptides. The status of lanthipeptides in terms of potential applications and approaches that are currently being done to promote the development of lanthipeptides as novel therapeutics are also discussed. Expert opinion: Significant improvements have been made to promote the discovery of new lanthipeptides, while, simultaneously, tools have been developed to promote their production and isolation. Lanthipeptides are showing significant promise for treating bacterial infections, as well as for new applications as anticancer and antiviral agents, or as a novel treatment for pain management. At the current rate of lanthipeptide discovery and isolation of the products, it is likely several new applications will be discovered. PMID- 29195490 TI - Marginal decision-making in the treatment of refractory epilepsy. AB - OBJECTIVE: Epilepsy surgery is one of the most effective treatments in modern medicine. Yet, it remains largely under-utilized, in spite of its proven efficacy. The referrals for epilepsy surgery are often delayed until it is too late to prevent the detrimental psychosocial effects of refractory seizures. The reluctance towards epilepsy surgery is influenced by the perceived risks of the procedure by practitioners and patients. This review discusses how, in general decision-making processes, one faces a natural tendency towards emphasizing the risks of the most immediate and operational decision (surgery), at times without contrasting these risks with the alternative (uncontrolled epilepsy). METHODS: In the field of economics, this bias is well recognized and can be overcome through marginal analysis, formally defined as focusing on incremental changes as opposed to absolute levels. RESULTS: Regarding epilepsy surgery, the risks and benefits of surgery are considered separately from the risks of uncontrolled epilepsy. For instance, even though surgery carries an ~0.1-0.5% risk of perioperative mortality, the chance of sudden unexpected death with refractory epilepsy can be as high as 0.6-0.9% per year. It is suggested that the inadequate way of phrasing clinical questions can be a crucial contributing factor for the under-utilization of epilepsy surgery. SIGNIFICANCE: It is proposed that examining decision-making for epilepsy surgery in the context of marginal analysis may enable providers and patients to make more accurate informed decisions. PMID- 29195489 TI - Secondary sex ratio in relation to exposures to polychlorinated biphenyls, dichlorodiphenyl dichloroethylene and methylmercury. AB - This study was undertaken to assess the potential impact of maternal exposures to polychlorinated biphenyl (PCB), dichlorodiphenyl dichloroethylene (DDE) and methylmercury on the secondary sex ratios (the ratio of male to female live births) over a span of 23 years. The study includes prospective data from three Faroese birth cohorts, with a total of 2,152 healthy mother-child dyads recruited between 1986 and 2009. The Faroe Islands is a subarctic fishing community, where pilot whale meat and blubber are part of the traditional marine diet. Exposures were measured in maternal hair, serum or umbilical cord blood. Confounder adjusted logistic regression models were used to assess the associations between maternal exposures and the secondary sex ratio. A doubling in SigmaPCB, p,p'-DDE and mercury concentrations were associated with increased odds by 8% (95% CI = 0 16%), 7% (95% CI = 0-14%) and 9% (95% CI = 2-17%), respectively, of giving birth to a boy. In conclusion, maternal exposure to SigmaPCB, DDE and methylmercury was associated with a slightly increased secondary sex ratio. The impact of paternal exposures could not be taken into account and deserves attention. PMID- 29195491 TI - ROS-mediated heme degradation and cytotoxicity induced by iron nanoparticles: hemoglobin and lymphocyte cells as targets. AB - Nanoparticles (NPs) due to their small size and high surface area induce remarkable adverse effects on the biological systems. However, the exact mechanism by which NPs interacted with biological system and induce their adverse effects is still an enigma. Herein, the interaction of zero valent iron NPs (ZVFe NPs) with human hemoglobin (Hb) was evaluated using a variety of techniques including circular dichroism, fluorescence, and UV-visible (UV-vis) spectroscopy methods. Also, the cytotoxicity of ZVFe NPs on the human lymphocyte cell line as a model of blood system cell line was investigated by reactive oxygen species (ROS), caspase-9, and caspase-3 activities assays. It was revealed that ZVFe NP interaction resulted in heme displacement and degradation and induction of protein cabonylation. It was also shown that ZVFe NPs impaired the complexity of lymphocyte cells through ROS generation and apoptotic pathway. Together, these data suggest that NPs influence the biological system and induce adverse effects through ROS generation.

PMID- 29195493 TI - Adiponectin, biomarkers of inflammation and changes in cardiac autonomic function: Whitehall II study. AB - BACKGROUND: Biomarkers of inflammation and adiponectin are associated with cardiovascular autonomic neuropathy (CAN) in cross-sectional studies, but prospective data are scarce. This study aimed to assess the associations of biomarkers of subclinical inflammation and adiponectin with subsequent changes in heart rate (HR) and heart rate variability (HRV) in non-diabetic and diabetic individuals. METHODS: Data are based on up to 25,050 person-examinations for 8469 study participants of the Whitehall II cohort study. Measures of CAN included HR and several HRV indices. Associations between baseline serum levels of high sensitivity C-reactive protein (hsCRP), interleukin (IL)-6, IL-1 receptor antagonist (IL-1Ra) and adiponectin and 5-year changes in HR and six HRV indices were estimated using mixed-effects models adjusting for age, sex, ethnicity, body mass index (BMI), metabolic covariates and medication. A modifying effect of diabetes was tested. RESULTS: Higher levels of IL-1Ra were associated with higher increases in HR. Additional associations with measures of HRV were observed for hsCRP, IL-6 and IL-1Ra, but these associations were explained by BMI and other confounders. Associations between adiponectin, HR and HRV differed depending on diabetes status. Higher adiponectin levels were associated with more pronounced decreases in HR and increases in three measures of HRV reflecting both sympathetic and vagal activity, but these findings were limited to individuals with type 2 diabetes. CONCLUSIONS: Higher IL-1Ra levels appeared as novel risk marker for increases in HR. Higher adiponectin levels were associated with a more favourable development of cardiovascular autonomic function in individuals with type 2 diabetes independently of multiple confounders. PMID- 29195494 TI - Implementation of a workplace intervention using financial rewards to promote adherence to physical activity guidelines: a feasibility study. AB - BACKGROUND: We designed and implemented the Brigham and Women's Wellness Initiative (B-Well), a single-arm study to examine the feasibility of a workplace program that used individual and team-based financial incentives to increase physical activity among sedentary hospital employees. METHODS: We enrolled sedentary, non-clinician employees of a tertiary medical center who self-reported low physical activity. Eligible participants formed or joined teams of three members and wore Fitbit Flex activity monitors for two pre-intervention weeks followed by 24 weeks during which they could earn monetary rewards. Participants were rewarded for increasing their moderate-to-vigorous physical activity (MVPA) by 10% from the previous week or for meeting the Centers for Disease Control and Prevention (CDC) physical activity guidelines (150 min of MVPA per week). Our primary outcome was the proportion of participants meeting weekly MVPA goals and CDC physical activity guidelines. Secondary outcomes included Fitbit-wear adherence and factors associated with meeting CDC guidelines more consistently. RESULTS: B-Well included 292 hospital employees. Participants had a mean age of 38 years (SD 11), 83% were female, 38% were obese, and 62% were non-Hispanic White. Sixty-three percent of participants wore the Fitbit >=4 days per week for >=20 weeks. Two-thirds were satisfied with the B-Well program, with 79% indicating that they would participate again. Eighty-six percent met either their personal weekly goal or CDC physical activity guidelines for at least 6 out of 24 weeks, and 52% met their goals or CDC physical activity guidelines for at least 12 weeks. African Americans, non-obese subjects, and those with lower impulsivity scores reached CDC guidelines more consistently. CONCLUSIONS: Our data suggest that a financial incentives-based workplace wellness program can increase MVPA among sedentary employees. These results should be reproduced in a randomized controlled trial. TRIAL REGISTRATION: Clinicaltrials.gov, NCT02850094 . Registered July 27, 2016 [retrospectively registered]. PMID- 29195495 TI - The effectiveness of vibrational stimulus to accelerate orthodontic tooth movement: a systematic review. AB - BACKGROUND: In recent years, it has been a hot research topic to accelerate orthodontic tooth movement (OTM) through vibration. This review was therefore aimed to systematically evaluate the available evidences on the efficacy of vibrational stimulus to accelerate OTM. METHODS: Randomized controlled trials and controlled clinical trials that evaluated the efficacy of vibration on OTM acceleration were searched through electronic and manual search. Two review authors independently conducted the study inclusion, quality assessment and data extraction. The quality of synthesized evidence was assessed according to GRADE system. RESULTS: Eight clinical trials were included in this systematic review. Four studies found that vibration did not enhance the rate of OTM during alignment phase. Two studies revealed that the use of vibratory stimulation accelerated canine retraction. No deleterious effects including pain perceptions and root resorptions were reported. CONCLUSIONS: Within the limitations of this review, weak evidence indicates that vibrational stimulus is effective for accelerating canine retraction but not for alignment. The effects of vibration on pain intensity and root resorption during orthodontic treatment are inconclusive. Future high-quality clinical trials are needed before warranting recommendations to clinical application. PMID- 29195496 TI - "Does the Salmonella Genomic Island 1 (SGI1) confer invasiveness properties to human isolates?" AB - BACKGROUND: In the eighties, a multidrug resistant clone of Salmonella Typhimurium DT104 emerged in UK and disseminated worldwide. This clone harbored a Salmonella genomic island 1 (SGI1) that consists of a backbone and a multidrug resistant region encoding for penta-resistance (ampicillin, chloramphenicol/florfenicol, streptomycin/spectinomycin, sulphonamides and tetracycline (ACSSuT)). Several authors suggested that SGI1 might have a potential role in enhancement of virulence properties of Salmonella enterica. The aim of this study was to investigate whether nontyphoidal S. enterica isolates carrying SGI1 cause more severe illness than SGI1 free ones in humans. METHODS: From 2011 to 2016, all patients infected with nontyphoidal S. enterica in our hospital were retrospectively included. All nontyphoidal S. enterica isolates preserved in our University Hospital (Dijon, France) were screened for the presence of SGI1. Clinical and biological data of patients were retrospectively collected to evaluate illness severity. Statistical analysis of data was performed by Kruskal-Wallis test or Fisher's exact test for univariate analysis, and by logistic regression for multivariate analysis. RESULTS: A total of 100 isolates of S. enterica (22 serovars) were collected. Twelve isolates (12%) belonging to 4 serovars harbored SGI1: S. Typhimurium, S. Infantis, S. Kentucky, S. St Paul. The severity of the disease was age-related (for invasive infection, sepsis and inflammatory response) and was associated with immunosuppression (for invasive infection, sepsis and bacteremia) but not with the presence of SGI1 or with antimicrobial resistance. CONCLUSION: A rather high proportion (12%) of human clinical isolates belonging to various serovars (for the first time serovar St Paul) and harboring various antimicrobial resistance profile carried SGI1. Diseases due to SGI1-positive S. enterica or to antimicrobial resistant isolates were not more severe than the others. This first clinical observation should be confirmed by a multicenter and prospective study. PMID- 29195497 TI - Bilateral uveitis and macular edema induced by Nivolumab: a case report. AB - BACKGROUND: Nivolumab is a fully human antibody which is routinely used at first therapy for metastatic melanoma. Usually, side effects are immune-related adverse events. We report a case of a man who developed bilateral anterior uveitis and macular serous retinal detachment during nivolumab treatment for metastatic melanoma. CASE PRESENTATION: A man on nivolumab treatment for a leg melanoma with duodenal and lymph nodes metastases developed a sudden bilateral visual acuity impairment and bilateral non-painfull redness eyes several days after the third infusion. The clinical examination showed a significant decreased of the visual acuity. Slit lamp examination revealed the presence of bilateral granulomatous keratic precipitates, anterior chamber cells +++, bilateral synechiae, bilateral papilledema and macular edema associated with serous retinal detachment in the left eye. The anti-Programmed cells Death-1 was stopped and a topical corticosteroid treatment was administrated. After 8 days of topical corticosteroid treatment visual acuity was worsening with similar optical coherence tomography examination. An oral corticosteroid treatment was started. Evolution was favorable with a decrease of ocular inflammation and a complete visual acuity recovery after 3 weeks. Nivolumab was re-initiated. CONCLUSIONS: This is the second clinical report of bilateral anterior uveitis associated with macular serous retinal detachment related to anti-PD-1 treatment, and the first with nivolumab. Cases of uveitis were reported several times. Although rare, ophthalmologic manifestations that are rapidly recognized and adequately managed can be treated.

PMID- 29195499 TI - Adjuvant chemotherapy improves survival of patients with high-risk upper urinary tract urothelial carcinoma: a propensity score-matched analysis. AB - BACKGROUND: The purposes of this study were to determine whether adjuvant chemotherapy (AC) improved the prognosis of patients with high-risk upper urinary tract urothelial carcinoma (UTUC)and to identify the patients who benefited from AC. METHODS: Among a multi-center database of 1014 patients who underwent RNU for UTUC, 344 patients with >= pT3 or the presence of lymphovascular invasion (LVI) were included. Cancer-specific survival (CSS) estimates were calculated by the Kaplan-Meier method, and groups were compared by the log-rank test. Each patient's probability of receiving AC depending on the covariates in each group was estimated by logistic regression models. Propensity score matching was used to adjust the confounding factors for selecting patients for AC, and log-rank tests were applied to these propensity score-matched cohorts. Cox proportional hazards regression modeling was used to identify the variables with significant interaction with AC. Variables included age, pT category, LVI, tumor grade, ECOG performance status and low sodium or hemoglobin score, which we reported to be a prognostic factor of UTUC. RESULTS: Of the 344 patients, 241 (70%) had received RNU only and 103 (30%) had received RNU+AC. The median follow-up period was 32 (range 1-184) months. Overall, AC did not improve CSS (P = 0.12). After propensity score matching, the 5-year CSS was 69.0% in patients with RNU+AC versus 58.9% in patients with RNU alone (P = 0.030). Subgroup analyses of survival were performed to identify the patients who benefitted from AC. Subgroups of patients with low preoperative serum sodium (<= 140 mEq/ml) or hemoglobin levels below the normal limit benefitted from AC (HR 0.34, 95% CI 0.15 0.61, P = 0.001). In the subgroup of patients with normal sodium and normal hemoglobin levels, 5-year CSS was 77.7% in patients with RNU+AC versus 80.2% in patients with RNU alone (P = 0.84). In contrast, in the subgroup of patients with low sodium or low hemoglobin levels, 5-year CSS was 71.0% in patients with RNU+AC versus 38.5% in patients with RNU alone (P < 0.001). CONCLUSIONS: High-risk UTUC patients, especially subgroups of patients with lower sodium and hemoglobin levels, could benefit from AC after RNU. PMID- 29195500 TI - An implantable pump Lenus pro(r) in the treatment of pulmonary arterial hypertension with intravenous treprostinil. AB - BACKGROUND: Subcutaneous treprostinil is a prostacyclin analogue used to treat pulmonary arterial hypertension (PAH). Due to local pain it can cause a deterioration of heart related quality of life (HRQoL) or even abandonment of treatment. The aim of this paper was to assess the feasibility of treatment with intravenous treprostinil administered by means of the Lenus Pro(r) implantable pump. METHODS: This was a retrospective, multi-center study involving 12 patients (8 females) with PAH treated with a subcutaneous infusion of treprostinil with intolerable pain at the infusion site. Clinical evaluation, including HRQoL assessment with SF-36 questionnaire was performed, before pump implantation and 2 9 months after. The median time of follow-up time was 14 months (4-29 months). RESULTS: After implantation of the Lenus Pro(r) pump, no statistically significant changes were observed in the 6-min walking distance and NT-proBNP. After implantation 50% of patients were in II WHO functional class (33% before, p = 0,59). There was a significant improvement in HRQoL within the Physical Component Score (28 +/- 7 vs 38 +/- 8 pts., p < 0,001) and in specific domains of SF-36 form: physical role (31 +/- 7 pts. vs. 41 +/- 12 pts., p = 0,03), bodily pain (31 +/- 12 vs. 50 +/- 14 pts., p = 0,02), and vitality (37 +/- 8 pts. vs. 50 +/- 14 pts., p = 0,03). During the periprocedural period, one patient developed a recurrent haematoma at the implantation site. During follow-up in one patient, the drug delivering cannula slipped out of the subclavian vein, what required repositioning repeated twice, and in another patient an unexpected increase in the drug administration rate was observed. CONCLUSIONS: In patients with PAH who do not tolerate subcutaneous infusion of treprostinil, the use of the Lenus Pro(r) implantable pump results in significant subjective improvement of vitality and physical aspect of the HRQoL with acceptable safety profile. PMID- 29195501 TI - COMT genotype and non-recovery after a whiplash injury in a Northern European population. AB - BACKGROUND: The COMT (Catechol-O-Methyl Transferase) gene may influence a person's vulnerability to develop long-term pain and some COMT single nucleotide polymorphisms (SNPs) may associate with patterns of acute or chronic pain. Many patients with whiplash-associated disorders (WADs) suffer from long-term pain and other related symptoms, but it is less known if genetic factors play a role in the recovery process. The primary aim of this study was to evaluate whether self reported non-recovery, including pain, was related to COMT genotype in patients with WAD. The secondary aim was to investigate whether or not background factors, including mental health, were related to genotype and non-recovery. METHODS: A total of 133 patients with neck pain after a whiplash trauma were included. Background factors were collected and blood samples were taken during the acute phase after the accident. DNA was isolated from blood and used to genotype the SNPs rs6269, rs4633, rs4818 and rs4680 in the COMT gene; additionally haplotypes were estimated and haplogenotypes inferred. The patients were followed up after 12 months and asked to rate their recovery including pain, mental health and quality of life. RESULTS: The overall reported non-recovery rate at 12 months was 44% with no significant differences in distribution of the COMT haplotypes. High levels of self-reported pain (OR 7.2) and anxiety (OR 4.4) after the accident were associated with non-recovery, but not related to the haplotypes. None of the other background factors were related to the haplotypes or non-recovery. CONCLUSION: No association between self-reported non-recovery or pain levels and COMT haplotypes in patients with acute whiplash injuries could be detected. Independent replications are necessary to discard the hypothesis that COMT haplotypes do not influence non-recovery or pain levels in patients with acute whiplash injuries. High levels of initial pain and anxiety were associated with non-recovery, thereby confirming previously published reports. PMID- 29195502 TI - OMSV enables accurate and comprehensive identification of large structural variations from nanochannel-based single-molecule optical maps. AB - We present a new method, OMSV, for accurately and comprehensively identifying structural variations (SVs) from optical maps. OMSV detects both homozygous and heterozygous SVs, SVs of various types and sizes, and SVs with or without creating or destroying restriction sites. We show that OMSV has high sensitivity and specificity, with clear performance gains over the latest method. Applying OMSV to a human cell line, we identified hundreds of SVs >2 kbp, with 68 % of them missed by sequencing-based callers. Independent experimental validation confirmed the high accuracy of these SVs. The OMSV software is available at http://yiplab.cse.cuhk.edu.hk/omsv/ .

AB - Antibodies against programmed death (PD) pathway are revolutionizing cancer immunotherapy. Currently five antibodies against PD-1/PD-L1 have been approved. The clinical use of these antibodies is rapidly expanding. Incorporation of PD antibodies into chemotherapy regimens is in active clinical investigations. The combination of pembrolizumab with carboplatin and pemetrexed has been approved for the first line therapy of metastatic non-squamous non-small cell lung cancer. Combination of PD-1/PD-L1 antibodies with small molecule inhibitors such as tyrosine kinase inhibitors and IDO inhibitors are in active clinical trials. This review summarized recent development in clinical trials of PD-1 and PD-L1 antibodies for cancer immunotherapy. PMID- 29195504 TI - Blinded by Zika? A missed HIV diagnosis that resulted in optic neuropathy and blindness: a case report. AB - BACKGROUND: Typical symptoms of an acute human immunodeficiency virus (HIV) infections like fever and rash are not specific and can be caused by a multitude of other pathogens, such as Zika or rickettsiosis. Up to 30% of primary HIV infection do not present with the typical flu-like symptoms and thus represent a diagnostic challenge. In this report, we describe a rare case of optic neuropathy as the initial presentation of primary HIV infection, which resulted in irreversible blindness. To our knowledge, only four cases of optic neuropathy resulting from a recent HIV seroconversion have been reported. CASE PRESENTATION: In January 2015, a 72-year-old man presented with a rash, fever and diffuse myalgias after returning from a fortnight in Cuba. In the context of the current polemic, Zika was considered likely. A diagnostic work-up, including dengue fever and Zika, was negative. Symptoms resolved spontaneously. In March, the patient experienced a sudden loss of vision first on one, a few days later on the other eye. Magnetic resonance imaging showed optic nerve enhancement suggesting neuritis. Numerous infective causes were sought and the patient was diagnosed with HIV. Corticosteroids and antiretroviral therapy were initiated but vision did not improve. Four weeks later an optic atrophy developed. After more than a year of follow-up the patient remains blind. Stored serum from January revealed a detectable viremia with a negative Western blot assay, typical of acute HIV infection. CONCLUSIONS: Optic neuritis is a rare complication of early HIV infection. Only four others cases have been described, some of which recovered their vision after the administration of corticosteroids and/or ARV treatment. The balance between ischemic and neuroimmune processes may play a role in recovery. Delayed diagnosis, due to an unjustified focus on the Zika virus may have contributed to the tragic outcome. PMID- 29195505 TI - Type 2 diabetes mellitus is associated with a lower fibrous cap thickness but has no impact on calcification morphology: an intracoronary optical coherence tomography study. AB - BACKGROUND: Patients with type 2 diabetes (T2DM) are at high risk for cardiovascular events, which usually arise from the rupture of a vulnerable coronary plaque. The minimal fibrous cap thickness (FCT) overlying a necrotic lipid core is an established predictor for plaque rupture. Recently, coronary calcification has emerged as a relevant feature of plaque vulnerability. However, the impact of T2DM on these morphological plaque parameters is largely unexplored. Therefore, this study aimed to compare differences of coronary plaque morphology in patients with and without T2DM with a particular focus on coronary calcification. METHODS: In 91 patients (T2DM = 56, non-T2DM = 35) with 105 coronary de novo lesions (T2DM = 56, non-T2DM = 49) plaque morphology and calcification were analyzed using optical coherence tomography (OCT) prior to coronary intervention. RESULTS: Patients with T2DM had a lower minimal FCT (80.4 +/- 27.0 um vs. 106.8 +/- 27.8 um, p < 0.001) and a higher percent area stenosis (77.9 +/- 8.1% vs. 71.7 +/- 11.2%, p = 0.001) compared to non-diabetic subjects. However, patients with and without T2DM had a similar total number of calcifications (4.0 +/- 2.6 vs. 4.2 +/- 3.1, p = ns) and no significant difference was detected in the number of micro- (0.34 +/- 0.79 vs. 0.31 +/- 0.71), spotty (2.11 +/- 1.77 vs. 2.37 +/- 1.89) or macro-calcifications (1.55 +/- 1.13 vs. 1.53 +/- 0.71, all p = ns). The mean calcium arc (82.3 +/- 44.8 degrees vs. 73.7 +/- 31.6), the mean thickness of calcification (0.54 +/- 0.13 mm vs. 0.51 +/- 0.15 mm), the mean calcified area (0.99 +/- 0.72 mm2 vs. 0.78 +/- 0.49 mm2), the mean depth of calcification (172 +/- 192 MUm vs. 160 +/- 76 MUm) and the cap thickness overlying the calcification (50 +/- 71 MUm vs. 62 +/- 61 MUm) did not differ between the diabetic and non-diabetic groups (all p = ns). CONCLUSION: T2DM has an impact on the minimal FCT of the coronary target lesion, but not on localization, size, shape or extent of calcification. Thus, the minimal FCT overlying the necrotic lipid core but not calcification is likely to contribute to the increased plaque vulnerability observed in patients with T2DM. PMID- 29195506 TI - Treatment of meningioma and glioma with protons and carbon ions. AB - The rapid rise of particle therapy across the world necessitates evidence to justify its ever-increasing utilization. This narrative review summarizes the current status of these technologies on treatment of both meningiomas and gliomas, the most common benign and malignant primary brain tumors, respectively. Proton beam therapy (PBT) for meningiomas displays high rates of long-term local control, low rates of symptomatic deterioration, along with the potential for safe dose-escalation in select (but not necessarily routine) cases. PBT is also associated with low adverse events and maintenance of functional outcomes, which have implications for quality of life and cost-effectiveness measures going forward. Data on carbon ion radiation therapy (CIRT) are limited; existing series describe virtually no high-grade toxicities and high local control. Regarding the few available data on low-grade gliomas, PBT provides opportunities to dose escalate while affording no increase of severe toxicities, along with maintaining appropriate quality of life. Although dose-escalation for low-grade disease has been less frequently performed than for glioblastoma, PBT and CIRT continue to be utilized for the latter, and also have potential for safer re-irradiation of high grade gliomas. For both neoplasms, the impact of superior dosimetric profiles with endpoints such as neurocognitive decline and neurologic funcionality, are also discussed to the extent of requiring more data to support the utility of particle therapy. Caveats to these data are also described, such as the largely retrospective nature of the available studies, patient selection, and heterogeneity in patient population as well as treatment (including mixed photon/particle treatment). Nevertheless, multiple prospective trials (which may partially attenuate those concerns) are also discussed. In light of the low quantity and quality of available data, major questions remain regarding economic concerns as well. PMID- 29195507 TI - Expert consensus on re-irradiation for recurrent glioma. AB - PURPOSE: To investigate radiation oncologists' opinions on important considerations to offering re-irradiation (re-RT) as a treatment option for recurrent glioma. MATERIALS AND METHODS: A survey was conducted with 13 radiation oncologists involved in the care of central nervous system tumor patients. The survey was comprised of 49 questions divided into 2 domains: a demographic section (10 questions) and a case section (5 re-RT cases with 5 to 6 questions representing one or several re-RT treatment dilemmas as may be encountered in the clinic). Respondents were asked to rate the relevance of various factors to offering re-RT, respond to the cases with a decision to offer re-RT vs. not, volume to be treated, margins to be employed, dose/fractionation suggested and any additional comments with respect to rationale in each scenario. RESULTS: Sixty nine percent of responders have been practicing for greater than 10 years and 61% have re-RT 20 to 100 patients to date, with 54% seeing 2-5 re-RT cases per month and retreating 1-2 patients per month. Recurrent tumor volume, time since previous radiation therapy, previously administered dose to organs at risk and patient performance status were rated by the majority of responders (85%, 92%, 77%, and 69% respectively) as extremely relevant or very relevant to offering re-RT as an option. CONCLUSION: The experts' practice of re-RT is still heterogeneous, reflecting the paucity of high-quality prospective data available for decision-making. Nevertheless, practicing radiation oncologists can support own decisions by referring to the cases found suitable for re-RT in this survey. PMID- 29195508 TI - THBD sequence variants potentially related to recurrent pregnancy loss. AB - Recurrent pregnancy loss (RPL) is a frequently occurring disease, which is classified as idiopathic in more than 50% of cases. THBD, the endothelial cell receptor for thrombin, has been associated with distinct biological processes and considered a coherent RPL-related candidate gene. In the present study, we have sequenced the complete coding region of THBD in 262 patients affected by RPL. Bioinformatics analysis and screening of controls strongly suggested that the THBD-p.Trp153Gly mutation might be related to RPL aetiology. It could be used, after its validation by functional assays, as a molecular marker for diagnostic/prognostic purposes. PMID- 29195509 TI - DPP-4 inhibition with linagliptin ameliorates the progression of premature aging in klotho-/- mice. AB - BACKGROUND: The potential of anti-aging effect of DPP-4 inhibitors is unknown. This study was performed to determine whether linagliptin, a DPP-4 inhibitor, could protect against premature aging in klotho-/- mice. METHODS: Klotho-/- mice exhibit multiple phenotypes resembling human premature aging, including extremely shortened life span, cognitive impairment, hippocampal neurodegeneration, hair loss, muscle atrophy, hypoglycemia, etc. To investigate the effect of linagliptin on these aging-related phenotypes, male klotho-/- mice were divided into two groups: (1) control group fed the standard diet, and (2) linagliptin group fed the standard diet containing linagliptin. Treatment with linagliptin was performed for 4 weeks. The effect of linagliptin on the above mentioned aging related phenotypes was examined. RESULTS: Body weight of klotho-/- mice was greater in linagliptin group than in control group (11.1 +/- 0.3 vs 9.9 +/- 0.3 g; P < 0.01), which was associated with greater gastrocnemius muscle weight (P < 0.01) and greater kidney weight (P < 0.05) in linagliptin group. Thus, linagliptin significantly prevented body weight loss in klotho-/- mice. Survival rate of klotho-/- mice was greater in linagliptin group (93%) compared to control group (67%), although the difference did not reach statistical significance (P = 0.08). None of linagliptin-treated klotho-/- mice had alopecia during the treatment (P < 0.05 vs control klotho-/- mice). Latency of klotho-/- mice in passive avoidance test was larger in linagliptin group than in control group (P < 0.05), indicating the amelioration of cognitive impairment by linagliptin. Cerebral blood flow of klotho-/- mice was larger in linagliptin group than in control group (P < 0.01), being associated with greater cerebral phospho-eNOS levels (P < 0.05) in linagliptin group. Neuronal cell number in hippocampal CA1 region was greater in linagliptin group than in control group (P < 0.05). Linagliptin group had greater cerebral phospho-Akt (P < 0.05) and phospho-CREB (P < 0.05) than control group. Thus, linagliptin ameliorated brain aging in klotho-/ mice. The degree of hypoglycemia in klotho-/- mice was less in linagliptin group than in control group, as estimated by the findings of OGTT. CONCLUSIONS: Out work provided the evidence that DPP-4 inhibition with linagliptin slowed the progression of premature aging in klotho-/- mice, and provided a novel insight into the potential role of DPP-4 in the mechanism of premature aging. PMID- 29195511 TI - Orthodontic management by functional activator treatment: a case report. AB - BACKGROUND: Managing orthodontic treatment is often very difficult for the orthodontist. Many devices are used during the orthopedic phase of orthodontic treatment, always with different functions. We describe a case of orthodontic management treated with the Equilibrator O.S.A. device (equilibrator designed by Ovidi, Santi, and Aprile for Eptamed SRL; Cesena, Italy; www.eptamed.com ). CASE PRESENTATION: A healthy 10-year-old white boy presented with a skeletal class II, division 1 malocclusion, molar class II, exhibiting an overjet of 7 mm prior to treatment. For treatment, we only used the Equilibrator O.S.A. device. CONCLUSIONS: We successfully treated an orthopedic/orthodontic case with a particular device that we describe here. PMID- 29195510 TI - Cerebrovascular pathology in Down syndrome and Alzheimer disease. AB - People with Down syndrome (DS) are at high risk for developing Alzheimer disease (AD) with age. Typically, by age 40 years, most people with DS have sufficient neuropathology for an AD diagnosis. Interestingly, atherosclerosis and hypertension are atypical in DS with age, suggesting the lack of these vascular risk factors may be associated with reduced cerebrovascular pathology. However, because the extra copy of APP leads to increased beta-amyloid peptide (Abeta) accumulation in DS, we hypothesized that there would be more extensive and widespread cerebral amyloid angiopathy (CAA) with age in DS relative to sporadic AD. To test this hypothesis CAA, atherosclerosis and arteriolosclerosis were used as measures of cerebrovascular pathology and compared in post mortem tissue from individuals with DS (n = 32), sporadic AD (n = 80) and controls (n = 37). CAA was observed with significantly higher frequencies in brains of individuals with DS compared to sporadic AD and controls. Atherosclerosis and arteriolosclerosis were rare in the cases with DS. CAA in DS may be a target for future interventional clinical trials. PMID- 29195513 TI - Factors Related to Co-Offending and Coerced Offending Among Female Sex Offenders: The Role of Childhood and Adult Trauma Histories. AB - Research suggests two important domains of women's sexual offending: co offending, in which additional perpetrators are present with the woman during the crime, and coerced offending, in which the woman feels pressured by someone else to commit the crime. This exploratory analysis examines these 2 domains using self-report data from 60 incarcerated female sex offenders (FSOs) in a Midwestern state. In addition to indicating whether a co-offender was present and whether they felt pressure to commit the sex offense for which they were incarcerated, participants provided demographic information about themselves, the victim, and the offense, as well as about their own trauma, substance abuse, and mental illness histories. Results indicate that childhood and adult trauma histories are related to both co-offending and coerced offending among FSOs. Implications for theory, policy and practice, and future research are discussed. PMID- 29195514 TI - College Students' Perspectives on Campus Health Centers as a Sexual Assault Resource: A Qualitative Analysis. AB - Students' perspectives of student health centers as a resource for sexual violence were examined. A qualitative, descriptive research design was used. Data were collected from 37 female undergraduate students in March 2016. Four focus groups were conducted and analyzed using thematic analysis techniques. Three themes emerged: (a) supports and barriers to using student health centers for sexual violence; (b) student health centers' responsibility to educate students about sexual violence; and (c) student health centers' responsibility to use campus-wide, comprehensive sexual violence efforts. Participants provided several recommendations to assist student health centers with addressing sexual violence. To maximize utility as an on-campus sexual violence resource, student health centers should foster a climate that is supportive of students' use of the facility and tailor their efforts to address students' needs. Student health center recommendations and suggestions for future research are provided. PMID- 29195512 TI - Blood-brain barrier hyperpermeability precedes demyelination in the cuprizone model. AB - In neuroinflammatory disorders such as multiple sclerosis, the physiological function of the blood-brain barrier (BBB) is perturbed, particularly in demyelinating lesions and supposedly secondary to acute demyelinating pathology. Using the toxic non-inflammatory cuprizone model of demyelination, we demonstrate, however, that the onset of persistent BBB impairment precedes demyelination. In addition to a direct effect of cuprizone on endothelial cells, a plethora of inflammatory mediators, which are mainly of astroglial origin during the initial disease phase, likely contribute to the destabilization of endothelial barrier function in vivo. Our study reveals that, at different time points of pathology and in different CNS regions, the level of gliosis correlates with the extent of BBB hyperpermeability and edema. Furthermore, in mutant mice with abolished type 3 CXC chemokine receptor (CXCR3) signaling, inflammatory responses are dampened and BBB dysfunction ameliorated. Together, these data have implications for understanding the role of BBB permeability in the pathogenesis of demyelinating disease. PMID- 29195515 TI - The Role of Objectification in the Victimization and Perpetration of Intimate Partner Violence. AB - Intimate partner violence (IPV) is a substantial health concern and identifying risk factors for IPV is a research priority. We examined the relationship between severe IPV and objectification of the self and other sex across participant sex. A sample of 1,005 male and female university students completed a series of online questionnaires that measure levels of self-objectification, objectification of the other sex, and histories of severe IPV victimization and perpetration. Self-objectification was associated with severe psychological aggression, physical assault, and sexual coercion victimization in females, but not in males. Objectification of the other sex was associated with severe psychological aggression and physical assault perpetration in males, but not in females. These findings contribute to our understanding of gender similarities and differences in IPV. PMID- 29195516 TI - Economic Abuse Within Intimate Partner Violence: A Review of the Literature. AB - This article reviews the literature on the measurement of, impact of, and interventions for economic abuse within intimate partner relationships. Current assessment measures for economic abuse, along with estimates of the prevalence of economic abuse, are reviewed and critiqued. Research exploring the impact of economic abuse on the victim's mental health and psychological well-being, family formations and parenting practices, and children's behaviors and youth outcomes are presented. Recently developed interventions, including financial literacy program models, are discussed and emphasized as a critical service to increase victims' economic self-efficacy, financial literacy, and financial behaviors. Finally, the review provides detailed recommendations on incorporating economic abuse as a central component of domestic violence research, practice, and policies. PMID- 29195517 TI - Organized Activity Participation and Relational Aggression: The Role of Positive Youth Development. AB - Relational aggression among early adolescents is a pervasive problem that negatively influences the health and well-being of youth. Strength-based approaches such as positive youth development (PYD) are a promising way to reduce risk of detrimental outcomes such as relational aggression. Participation in organized activities is a key way that youth build assets related to PYD. Yet, few researchers have examined empirically assets related to PYD as a mechanism by which organized activity participation may help reduce risk of relational aggression. In this study, we used structural equation modeling to investigate if assets associated with PYD mediate the relationship between organized activity participation and relational aggression using survey data from a diverse, school based sample of early adolescents (N = 196; mean age = 12.39 years; SD = 0.52; 60% female; 45% African American, 27% White, 21% multiracial, and 7% other, 71% economically disadvantaged). We tested 2 competing models, 1 with decomposed PYD factors and 1 with an integrated PYD factor. Our results suggest that PYD better fit as an integrated versus decomposed construct, providing support for the notion that youth benefit most from assets related to PYD when they operate collectively. Our results also provide support for PYD-related factors as a mechanism by which participation may reduce risk of relational aggression. Limitations of this study, and implications for prevention are discussed. PMID- 29195518 TI - Characteristics of Intimate Partner Violence Victimization Experienced by a Sample of Portuguese Men. AB - International research has established that men can be victims of intimate partner violence (IPV). In Portugal, this phenomenon has not yet received scientific or social attention, although since the 1990s, IPV has been acknowledged as a notable problem. An online cross-sectional study was conducted with 89 heterosexual men who, after completing the Revised Conflict Tactics Scales, identified themselves as victims of IPV. We examined the prevalence of IPV, its context, its perceived impact, men's reactions after an episode of violence, men's perceived motives for the partner's aggressive behavior, and reasons that prevented men from leaving the abusive relationship. The results revealed many similarities to the findings in the literature on female victims and are discussed in terms of their practical implications. Increased knowledge of this underreported phenomenon is vital to the development of suitable policies and support services. PMID- 29195519 TI - Reducing Violence in Correctional Institutions: Revalidation of the Inmate Risk Assessment for Violent, Nonsexual Victimization. AB - Jail and prison administrators are responsible for ensuring institutional safety and order. Recent estimates indicate violence in correctional institutions is pervasive. One promising approach to reduce institutional violence is using a risk assessment to predict the likelihood of victimization. Once corrections officials identify high victimization risk offenders, these authorities can take steps to triage interventions to mitigate such risks. This strategy, however, requires a classification instrument that is available and predictively valid. In 2014, Labrecque, Smith, and Wooldredge created one such tool-the Inmate Risk Assessment for Violent, Nonsexual Victimization (RVNSV). This study reassesses the predictive validity of the RVNSV on a sample of adult inmates in the United States. The results indicate the RVNSV is a valid predictor of inmate victimization, among males and females. PMID- 29195520 TI - Police Officers' Rape Myth Acceptance: Examining the Role of Officer Characteristics, Estimates of False Reporting, and Social Desirability Bias. AB - This study examines police officers' perceptions of sexual assault and those who report sexual assault to the police, using a revised version of the Rape Myth Acceptance Scale along with a measure of social desirability bias. The study includes survey responses from 174 officers from 1 mid-sized police department in the Great Lakes region. Results show low to moderate levels of rape myth acceptance scores on the Rape Myth Acceptance Scale, with highest scores related to victim lying. Officers report very high estimates of false reporting, indicating some rape myth acceptance. Officer level of education, rank, and estimates of false reporting influence rape myth acceptance; however, social desirability bias is an important explanatory factor. Implications for measurement and training are discussed. PMID- 29195521 TI - Caring Is Social. PMID- 29195522 TI - Our Capacity to Care. AB - Caring is meaningful work. Unfortunately, the conditions under which health care personnel work can reduce caring to an abstract principle that we name rather than an everyday practice that we do. Several factors curtail our ability to care, including the social construction of caring as feminine and thus less worthwhile; the churn of patients through clinics and hospitals; and associated responsibilities, such as those that have developed with greater use of electronic health records. Work-related stress can activate implicit biases, which unconsciously distance personnel from members of stigmatized groups and contribute to health care disparities. To improve our capacity to care, we must tackle the barriers to caring that exist both within and external to clinics and hospitals. PMID- 29195523 TI - Painful Reality: Inappropriate Provider Management of Pain as a Determinant of Health Care Avoidance. AB - Although pain is often characterized as a subjective, highly individualized phenomenon, in fact, numerous elements which are simply biological in nature underlie interpersonal differences in pain experience that influence the effectiveness of provider pain management. Elements acting at the level of tissues and cells include signal-transmitting molecules in pain pathways; elements acting at the level of the whole person comprise entire brain networks and anatomic elements fostering pain vulnerability. However, knowledge of these elements and translation of such knowledge into practical means for relieving patient pain is dismayingly sparse across the total spectrum of health care professionals. A serious consequence of this knowledge and action gap is that isolated, or worse yet, repeated, pain experiences may lead to profound mistrust of the health care system and its providers and to health care avoidance (e.g., mammography). This article outlines a biologic knowledge base and proposed remedies to improve pain management across the entire domain of health care. Key components of this approach include enhanced education for providers and informational outreach to health care consumers, clarifying pain mechanisms to both constituencies. Moreover, increased accountability within the health care system is needed, both in knowing and applying well-established biomedical knowledge and in best using technical and interpersonal skills necessary for effective pain management. PMID- 29195524 TI - Race, Racism, and Health Disparities: What Can I Do About It? AB - Disparities based on race that target communities of color are consistently reported in the management of many diseases. Barriers to health care equity include the health care system, the patient, the community, and health care providers. This article focuses on the health care system as well as health care providers and how racism and our implicit biases affect our medical decision making. Health care providers receive little or no training on issues of race and racism. As a result, awareness of racism and its impact on health care delivery is low. I will discuss a training module that helps improve awareness around these issues. Until racial issues are honestly addressed by members of the health care team, it is unlikely that we will see significant improvements in racial health care disparities for Americans. PMID- 29195525 TI - Second Life Patient Scenarios: Enhancing the Diversity of the Nursing Profession. AB - Despite the current transformation of the U.S. population to one of increased diversity, the majority of nurses employed are from White backgrounds. In addition, few secondary school students from ethnically diverse backgrounds or from rural regions in the nation are encouraged to pursue a collegiate education or to consider nursing as a career. This article describes an innovative 3-year program in which one rural university in the southeast used a virtual environment, Second Life, to expose secondary students to nursing through role playing as avatars interacting with patient case scenarios. Secondary school science and health occupations teachers developed patient and environmental scenarios under the direction of the nursing program director and the information technology director from the university. Throughout the 3 years, 300 rural and multicultural students were exposed to virtual world health care learning through quizzes with five patient case and environmental scenarios. Student and teacher evaluations were positive about their interest in learning obtained through the patient case examinations. Technical difficulties during Year 1 were eliminated by Year 3. This program demonstrates that use of virtual technologies such as Second Life may increase the interest of secondary rural and multicultural students in careers in nursing and in pursuing a collegiate education. PMID- 29195527 TI - Servant Leadership, Emotional Intelligence: Essential for Baccalaureate Nursing Students. AB - Baker University Bachelor of Science in Nursing students study servant leadership and emotional intelligence in a Leadership and Management in Professional Nursing course. The acquisition of these skills increases collaboration with clients and colleagues. Servant leadership improves care through encouragement and facilitation rather than power (Waterman, 2011). Emotional intelligence allows individuals to deal effectively with emotions and is associated with better health (Por, Barriball, Fitzpatrick, & Roberts, 2011). Knowledge of servant leadership, combined with emotional intelligence, creates a relationship with self; encourages relationships with others, clients, and providers; allows teamwork participation; and impacts the entire community. PMID- 29195526 TI - Use of Simulated Psychosocial Role-Playing to Enhance Nursing Students' Development of Soft Skills. AB - Effective communication and interaction enable nurses to develop caring, empathetic, and respectful relationships with patients and families. However, most nurses feel a lack of preparation in the "soft" skills of communication, professionalism, and leadership. Nurse managers are seeking graduates with strong emotional quotient characteristics such as self-awareness, motivation, self regulation, empathy, and social skills. Assisting nursing students to develop these intangible, high-level skills presents an ongoing challenge to nurse educators. This creative teaching learning strategy examines the use of psychosocial role-playing skits to enhance nursing student development of the soft skills of nursing. In this strategy, senior level nursing students work in small groups to develop and present realistic 3- to 5-minute skits based on common nurse-patient, nurse-family, or nurse-health care team interactions that incorporate the concepts of therapeutic communication, interpersonal interaction, empathy, active listening, teamwork, delegation, and/or professionalism, followed by a debriefing session. Student feedback suggests that confidence and competence related to the skills of therapeutic communication, interpersonal interaction, empathy, active listening, teamwork, delegation, and professionalism may improve by incorporating soft skill psychosocial role-playing into a nursing education course of study.

By providing adequate scaffolding, clinical instructors can help empower nursing students as they begin to provide care in a variety of clinical settings. This article presents the 14 golden rules for clinical day, a unique form of scaffolding based on my own experience as a nursing clinical instructor. The right scaffolding can help students to overcome the sense of otherness they often experience at clinical sites and to blossom into competent, confident nurses who put their patients first. PMID- 29195529 TI - Building Relationship-Based Care Among Nurses: A Holistic, Exploratory Project. AB - In this exploratory project, efforts were made to strengthen a relationship centered, caring milieu to improve communication among nursing staff and to help nurses identify and constructively resolve conflicts. Eighteen interactive workshops addressed communication patterns and helped participants identify causes of conflict, facilitate dialogue, improve collaboration, and resolve workplace conflict. The experiential workshops were analyzed with pre- and post surveys. Participants perceived as individual and team members that it was less important to like one's colleagues and more important to be committed to the same purpose/goals. Individuals noted the value of respect for each other, regardless of title or position. They reported feeling more hopeful regarding work and that practicing tactics to address conflicts made it easier to confront others when the team goal was clear and shared. They indicated a desire to continue to build on conflict resolution, mediation, stress management, and mindfulness skills.

Homelessness is associated with poor health, and homeless women experience earlier mortality than their housed counterparts. Understanding the aspirations of homeless women may offer service providers avenues for intervention to increase well-being among this vulnerable population. This study, a secondary analysis of transcribed interviews (n = 20), provides insight into the aspirations of homeless women. Opportunities for service providers to intervene on these aspirations within the context of homelessness are offered. PMID- 29195531 TI - Workplace Violence Against Nurses: Making It Safe to Care.

PMID- 29195534 TI - Identifying Indicators of Healthy Work Environments in Nursing as Determinants of Health in the 21st Century. AB - A paradigm shift is occurring in the definition of health and therefore also in the determinants of health. Social determinants of health, considered by many to be the premises of good health and a purposeful life, are now the focus of attention in determinants of health. These determinants of health bring attention to the conditions in which people are born and live and work. This article proposes that indicators of healthy work environments in nursing can be identified as determinants of health. Study findings from around the world confirm that the health and well-being of nurses and their patients is related to nurses' work and work environments. Therefore, the working lives of nurses should be identified as an inseparable part of their personal lives, leading to consideration of work environments and thereby the quality of nurse's work lives as determinants of health in the 21st century.

AB - Women refugees arrive in the United States often having experienced extreme levels of poverty, deprivation, and violence, including gender-based violence, which can severely affect their physical and psychological health and well-being. A women's group was initiated to improve the health and well-being of refugee women in Durham, North Carolina, through a collaboratively designed, culturally appropriate health literacy intervention for women based on mutually identified needs; to empower them to seek preventive health services and screening through knowledge and skills about health needs and access to care; and to create an environment for the development of a supportive social/peer network for the prevention of social isolation and mental health issues related to the refugee experience. PMID- 29195536 TI - Mountains, Melting Pot, and Microcosm: Health Care Delay and Dengue/Zika Interplay on Hawaii Island. AB - Human history in the Hawaiian Islands offers a sobering study in the population dynamics of infectious disease. The indigenous population numbering an estimated half million people prior to Western contact in 1778 was reduced to less than 24,000 by 1920. Much of the decline occurred in the earliest decades after contact with Western diseases including measles, chicken pox, polio, tuberculosis, and venereal disease. A recent outbreak on the Island of Hawaii (also called the Big Island) of imported dengue fever, an illness endemic in 100 countries affecting an estimated 100-400 million people worldwide, provides insights into the problems and prospects for health care policy in managing mosquito-borne disease in a multicultural setting of geographic isolation and health care provider shortage. This incident represents in microcosm a practice run, applicable in many contexts, for an initial localized appearance of Zika virus infection, with important lessons for effective health care management in a rapidly moving and fluid arena. PMID- 29195537 TI - Nurses See "The Big Picture": Addressing Climate Change as a Social Determinant of Global Health. AB - Although it is well known that health is influenced by social determinants, climate change is an underrepresented determinant of health within nursing and health care literature, curriculum, and practice. There is urgent need to recognize climate change as a current and future threat to human and environmental health. This article describes the role of nursing in taking action on climate change now and in the future. The profession of nursing, with its ongoing commitment to social justice and its unique position to collaborate with patients and other health care professionals, is particularly well situated to activate change to protect and promote the health of individuals, populations, and future generations.

The purpose of this article is to explore the benefit of recognizing the signs and symptoms of burnout, introduce interventions to combat PTSD, and improve resiliency in ED RNs. The use of the wounded healer theory provides a framework to help nurse managers develop strategies such as critical incident stress debriefing (CISD) to address emotional distress. PMID- 29195539 TI - Barriers to Teaching Social Determinants of Health: Nursing Study-Abroad Programs in a Digital Age. AB - The social determinants of health are the conditions in which humans are born, grow up, live, work, and age (World Health Organization [WHO], 2012). In nursing programs, this content is typically taught in community health courses. Another strategy for teaching students how to understand the social determinants of health is study-abroad courses. Budding nurses can learn how to assess conditions that influence the health of a community. Conducting this assessment in a culture that differs from the student's own can help highlight what factors impact one's own health. For the past eight years, the author has been teaching the social and cultural determinants of health to nursing students by taking them on 3-week cultural immersion/community health studyabroad programs. Destinations have included Ghana, Austria, the Netherlands, and Thailand.

AB - Evaluating the implementation of care models such as Primary Nursing requires assessment of both short-term and long-term outcomes. In a hospital in Piemonte, Italy, a mixedmethod time-series study was conducted to assess if and how the organizational culture of nurses changed in relation to the implementation of a new organizational model of care. Instruments used included the Condition of Work Effectiveness Questionnaire (CWEQ II) and an investigator-developed questionnaire to evaluate perceptions of dimensions consistent with Primary Nursing. Results showed a significant culture change over time related to the implementation of Primary Nursing, mainly in terms of nurses' understanding of their professional role specifications. In addition, the results supported a relationship between being involved in the project implementation and the procedural and cultural approach adopted. PMID- 29195542 TI - Communication With Patients and Families as a Global Determinant of Health: Lessons From Care of Children With Special Health Care Needs. AB - Until recently, patients and families were not considered by all providers to be valued members of the health care team. Many providers made decisions away from the bedside and then told the patient and family what they could expect from the plan of care. This top-down approach is not limited to one country or culture but reflects an attitude prevalent in biomedicine around the globe. However, the paradigm is beginning to shift. Skyrocketing health care costs have prompted value-based purchasing, in which third-party payment is linked to patient outcomes and satisfaction. Providers and health care organizations are scrambling for evidence-based models to improve communication and other satisfaction-related criteria. This article proposes that teaching patients and families use of the Situation/Background/Assessment/Recommendations (SBAR) tool, traditionally used among health care professionals, will improve communication, enhance patient and family satisfaction, and potentially improve patient outcomes overall. The SBAR4Patients project demonstrates the positive impact SBAR can have on parents of chronically ill children.

AB - PURPOSE: The study was undertaken to partially address the number one priority for Delaware County for 2013-2017: reducing chronic illness including heart disease and obesity (Delaware County Public Health, 2013). Thus, the purpose was to examine the effects of a 10-week walking program on outcomes, such as blood pressure (BP), total cholesterol (TC), high-density lipoprotein (HDL) levels, body mass index (BMI), 10-year cardiovascular risk, and results of a 6-minute walk test, for adult women in a rural community in New York. METHODS: A quasi experimental study conducted 8 paired t tests of pre- and postdata using Bonferroni correction for multiple t tests. A convenience sample of 70 retained 62 to completion. Pre- and post-BMI, TC, HDL, BP, and a 6-minute walk test data were collected for each participant. Pedometer activity was collected throughout the program with computer downloads at 5 and 10 weeks. Sociodemographic variables including age, self-reported ethnicity, and educational level were used to describe the sample and trends in the data. FINDINGS: Age range was 29-79 years (M = 55) years. Mean pretest weight was 181 lb; mean BMI was 30.7 kg/m2. There was a statistically significant improvement (p < .05) in weight, BMI, TC, systolic blood pressure (SBP), and 6-minute walk test. All comparisons retained significance except TC after the Bonferroni correction. There was also a statistically significant increase (p < .05) in aerobic steps from midway to end of study after an incentive raffle challenge was introduced. CONCLUSIONS: The data suggest that a community walking program using pedometers with tracking capabilities was successful in increasing steps and improving select cardiovascular disease (CVD) risk factors in a group of women in a rural community in New York.

PMID- 29195544 TI - Identifying Health Needs in Peru Through Use of a Community Survey. AB - Students and faculty from a Midwestern college conducted a neighborhood community needs assessment in an impoverished area of a Peruvian city to identify health needs of residents. Students interviewed residents in their homes, asking about the need for medical, dental, and ophthalmic care and screening for chronic conditions such as diabetes, heart disease, and tuberculosis. The survey provided necessary information to medical mission workers and allowed students to directly observe family living conditions while assessing psychosocial needs of the families interviewed. The challenges of this survey included differing expectations, language barriers, recruiting neighborhood volunteers, safety risks to students, and mistrust by neighborhood residents.

PMID- 29195547 TI - The role of interventricular conduction delay to predict clinical response with cardiac resynchronization therapy. AB - BACKGROUND: Pacing at sites with late electrical activation or greater interventricular delay is associated with improvement in measures of cardiac resynchronization therapy (CRT) response, primarily reverse remodeling. However, little is known about whether such lead positions improve heart failure (HF) clinical outcomes. OBJECTIVE: The purpose of this study was to assess the association between interventricular electrical delay and HF clinical outcomes. METHODS: The Pacing Evaluation-Atrial SUpport Study was a multicenter randomized trial of patients undergoing CRT-defibrillator implantation. Interventricular delay was measured as the unpaced right ventricle-left ventricle (RV-LV) interval in sinus rhythm. The HF clinical composite score was the primary end point. In addition, the time to first HF hospitalization or death was measured and events were adjudicated by a blinded core laboratory. The cohort was divided at the median RV-LV interval into short (<67 ms) and long (>=67 ms) subgroups. In addition, receiver operating characteristic curves were constructed to identify the optimal cutoff of the RV-LV interval and spline analysis was performed to assess RV-LV interval as a continuous variable. RESULTS: A total of 1342 patients were included in this study. The clinical composite score at 1 year differed between groups, with more patients improving and fewer patients worsening in the long RV-LV group (P = .014). The time to first HF hospitalization or mortality also differed with a lower risk of an event in the long RV-LV group (hazard ratio 0.62; P = .002). Multivariate analysis showed that RV-LV time (hazard ratio 0.71; P = .038) and sex were independent predictors of this outcome. CONCLUSION: Baseline interventricular delay is a strong independent predictor of clinical response to CRT.

PMID- 29195550 TI - A three-time-point method for assessing kinetic parameters of 64Cu-labeled Ramucirumab trapping in VEGFR-2 positive lung tumors. AB - OBJECTIVE: To describe a three-time-point method for estimating kinetic parameters involved in 64Cu-labeled Ramucirumab (64Cu-NOTA-RamAb) trapping of VEGFR-2 positive lung tumors. MATERIALS AND METHODS: Positron emission tomography (microPET) data of tumor-bearing mice for 64Cu-NOTA-RamAb trapping in VEGFR-2 positive HCC4006 tumor were used, involving tissue activity measurements acquired at 3, 24 and 48 h post-injection, without and with administration of RamAb blocking dose. A kinetic model provided an analytical formula describing the tissue time-activity-curve, involving 64Cu-NOTA-RamAb uptake (Ki), release rate constant (kR) and fraction of free tracer in blood and interstitial volume (F). RESULTS: Fitting analytical formula outcomes on mean microPET data yielded values of the kinetic parameters: Ki = 0.0314/0.0123 gram of blood per hour per gram of tissue, kR = 0.0387/0.0313 h-1 and F = 0.2075/0.2007 gram of blood per gram of tissue, without/with RamAb blocking dose, respectively (R = 0.99999 for the graph displaying microPET versus theoretical data; P < .01). CONCLUSIONS: Three independent kinetic parameters (Ki, kR and F) can be assessed from three data points acquired at early, mid and late imaging, i.e., at 3, 24 and 48 h post injection, for further characterization of 64Cu-NOTA-RamAb trapping in VEGFR-2 positive lung tumors. PMID- 29195551 TI - Effectiveness of a simple and real-time baseline shift monitoring system during stereotactic body radiation therapy of lung tumors. AB - PURPOSE: This study aimed to clinically validate a simple real-time baseline shift monitoring system in a prospective study of consecutive patients undergoing stereotactic body radiation therapy (SBRT) of lung tumors, and to investigate baseline shift due to intrafraction motion of the patient's body during lung SBRT. METHODS: Ten consecutive patients with peripheral lung tumors were treated by SBRT consisting of four fractions of 12 Gy each, with a total dose of 48 Gy. During treatment, each patient's geometric displacement in the anterior-posterior and left-right directions (the baseline shift) was measured using a real-time monitoring webcam system. Displacement between the start and end of treatment was measured using an X-ray fluoroscopic imaging system. The displacement measurements of the two systems were compared, and the measurements of baseline shift acquired by the monitoring system during treatment were analyzed for all patients. RESULTS: There was no significant deviation between the monitoring system and the X-ray imaging system, with the accuracy of measurement being within 1 mm. Measurements using the monitoring system showed that 7 min of treatment generated displacements of more than 1 mm in 50% of the patients. CONCLUSIONS: Baseline shift of a patient's body may be measured accurately in real time, using a monitoring system without X-ray exposure. The manubrium of the sternum is a good location for measuring the baseline shift of a patient's body at all times. The real-time monitoring system may be useful for measuring the baseline shift of a patient's body independently of a gating system. PMID- 29195552 TI - Geometric and dosimetric quality assurance using logfiles and a 3D helical diode detector for Dynamic WaveArc. AB - PURPOSE: To conduct patient-specific geometric and dosimetric quality assurance (QA) for the Dynamic WaveArc (DWA) using logfiles and ArcCHECK (Sun Nuclear Inc., Melbourne, FL, USA). METHODS: Twenty DWA plans, 10 for pituitary adenoma and 10 for prostate cancer, were created using RayStation version 4.7 (RaySearch Laboratories, Stockholm, Sweden). Root mean square errors (RMSEs) between the actual and planned values in the logfiles were evaluated. Next, the dose distributions were reconstructed based on the logfiles. The differences between dose-volumetric parameters in the reconstructed plans and those in the original plans were calculated. Finally, dose distributions were assessed using ArcCHECK. In addition, the reconstructed dose distributions were compared with planned ones. RESULTS: The means of RMSEs for the gantry, O-ring, MLC position, and MU for all plans were 0.2 degrees , 0.1 degrees , 0.1 mm, and 0.4 MU, respectively. Absolute means of the change in PTV D99% were 0.4 +/- 0.4% and 0.1 +/- 0.1% points between the original and reconstructed plans for pituitary adenoma and prostate cancer, respectively. The mean of the gamma passing rate (3%/3 mm) between the measured and planned dose distributions was 97.7%. In addition, that between the reconstructed and planned dose distributions was 99.6%. CONCLUSIONS: We have demonstrated that the geometric accuracy and gamma passing rates were within AAPM 119 and 142 criteria during DWA. Dose differences in the dose volumetric parameters using the logfile-based dose reconstruction method were also clinically acceptable in DWA. PMID- 29195553 TI - Impact of a monolithic silicon detector operating in transmission mode on clinical photon beams. AB - PURPOSE: To investigate the effect on surface dose, as a function of different field sizes and distances from the solid water phantom to transmission detector (Dsd), of using the monolithic silicon detector MP512T in transmission mode. METHODS: The influence of operating the MP512T in transmission mode on the surface dose of a phantom for SSD 100cm was evaluated by using a Markus IC. The MP512T was fixed to an adjustable stand holder and was positioned at different Dsd, ranging from 0.3 to 24 cm. For each Dsd, measurements were carried out for irradiation field sizes of 5 * 5cm2, 8 * 8 cm2 and 10 * 10 cm2. Measurements were obtained under two different operational setups, (i) with the MP512T face-up and (ii) with the MP512T face-down. In addition, the transmission factors for the MP512T and the printed circuit board were only evaluated using a Farmer IC. RESULTS: For all Dsd and all field sizes, the MP512T led to the surface dose increasing by less than 25% when in the beam. For Dsd >18 cm the surface dose increase is less than 5%, and negligible for field size 5 * 5 cm2. The difference in the surface dose perturbation for the MP512T operating face up or operating face down is negligible (<2%) for all field sizes. The transmission factor of the MP512T ranged from 1.020 to 0.9950 for all measured Dsd and field sizes. CONCLUSION: The study demonstrated that positioning the MP512T in air between the Linac head and the phantom produced negligible perturbation of the surface dose for Dsd >18 cm, and was completely transparent for 6 MV photon beams. PMID- 29195554 TI - Numerical insight into the Dual Radiation Action Theory. AB - This work studies the first and second order mechanisms for the induction of lethal lesions in DNA after irradiation with protons and alpha-particles. The purpose is to numerically study the mechanisms behind the Dual Radiation Action Theory (DRAT) for these heavy particles. A genetic material geometrical model with atomic resolution is used. It accounts for the explicit position of 5.47 * 109 base pairs, organized up to the chromatin level. The GEANT4-DNA Monte Carlo code was employed to simulate the interaction of these ions with the genetic material model. The number of lethal lesions induced by one- and two-track mechanisms was determined as a function of dose. Values of the alpha/beta ratio were estimated as well as corresponding relative biological effectiveness (RBE). The number of lethal lesions produced by one-track and two-track mechanisms depends on the dose and squared dose, respectively, as predicted by the DRAT. RBE values consistent with experimental results were found, at least for LET below ~100 keV/MUm. Double strand break spatial distributions are qualitatively analyzed. According to this work, the alpha parameter determined from cellular surviving curves depends on both the physical alpha and beta parameters introduced here, and on the specific energy deposited by a single track into the region of interest. We found an increment of the beta parameter with LET, yet at a slower rate than alpha so that the alpha/beta ratio increases with LET. In addition, we observed and explained the saturation of the alpha parameter as the dose increases above ~6 Gy. PMID- 29195555 TI - Feasibility of beta-particle radioguided surgery for a variety of "nuclear medicine" radionuclides. AB - PURPOSE: Beta-particle radioguided tumor resection may potentially overcome the limitations of conventional gamma-ray guided surgery by eliminating, or at least minimizing, the confounding effect of counts contributed by activity in adjacent normal tissues. The current study evaluates the clinical feasibility of this approach for a variety of radionuclides. Nowadays, the only beta- radioisotope suited to radioguided surgery is 90Y. Here, we study the beta- probe prototype capability to different radionuclides chosen among those used in nuclear medicine. METHODS: The counting efficiency of our probe prototype was evaluated for sources of electrons and photons of different energies. Such measurements were used to benchmark the Monte Carlo (MC) simulation of the probe behavior, especially the parameters related to the simulation of the optical photon propagation in the scintillation crystal. Then, the MC simulation was used to derive the signal and the background we would measure from a small tumor embedded in the patient body if one of the selected radionuclides is used. RESULTS: Based on the criterion of detectability of a 0.1 ml tumor for a counting interval of 1 s and an administered activity of 3 MBq/kg, the current probe yields a detectable signal over a wide range of Standard Uptake Values (SUVs) and tumor-to-non-tumor activity-concentration ratios (TNRs) for 31Si, 32P, 97Zr, and 188Re. Although efficient counting of 83Br, 133I, and 153Sm proved somewhat more problematic, the foregoing criterion can be satisfied for these isotopes as well for sufficiently high SUVs and TNRs. PMID- 29195556 TI - Immobilization for carbon ion beam ablation of cardiac structures in a porcine model. AB - INTRODUCTION: Whereas hadron therapy of static targets is clinically established, treatment of moving organs remains a challenge. One strategy is to minimize motion of surrounding tissue mechanically and to mitigate residual motion with an appropriate irradiation technique. In this technical note, we present and characterize such an immobilization technique for a novel noncancerous application: the irradiation of small targets in hearts with scanned carbon ion beams in a porcine model for elimination of arrhythmias. MATERIAL AND METHODS: A device for immobilization was custom-built. Both for the treatment planning 4D-CT scan and for irradiation, breath-hold at end-exhale was enforced using a remotely controlled respirator. Target motion was thus reduced to heartbeat only. Positioning was verified by orthogonal X-rays followed by couch shift if necessary. Reproducibility of bony anatomy, diaphragm, and heart position after repositioning and between repeated breath-hold maneuvers was evaluated on X-rays and cardiac-gated 4D-CTs. Treatment was post hoc simulated on sequential 4D-CTs for a subset of animals, after immediate repositioning and after a delay of one week, similar to the delay between imaging and irradiation. RESULTS: Breath-hold without repositioning was highly reproducible with an RMS deviation of at most one millimeter. 4D-CTs showed larger deformations in soft tissue, but treatment simulation on sequential images resulted in full target coverage (V95 >95%). CONCLUSION: The method of immobilization permitted reproducible positioning of mobile, thoracic targets for range-sensitive particle therapy. The presented immobilization strategy could be a reasonable approach for future animal investigations with the ultimate goal of translation to therapy in men. PMID- 29195557 TI - Eye lens radiation exposure of the medical staff performing interventional urology procedures with an over-couch X-ray tube. AB - The purpose of this work was to estimate the eye lens radiation exposure of the medical staff during interventional urology procedures. The measurements were carried out for six medical staff members performing 33 fluoroscopically-guided procedures. All procedures were performed with the X-ray tube positioned over the couch. The dose equivalents (Hp(0.07)) were measured at the eye level using optically stimulated luminescent (OSL) dosimeters and at the chest level with OSL dosimeters placed over the protective apron. The ratio of the dose measured close to the eye lens and on the chest was determined. The annual eye lens dose was estimated based on the workload in the service. For the physician and the instrumentalist nurse, the eye to chest dose ratios were 0.9+/-0.4 and 2.6+/-1.6 (k = 2), respectively. The average doses per procedure received by the eye lens were 78+/-24 MUSv and 38+/-18 MUSv, respectively. The eye lens dose per DAP was 8.4+/-17.5 MUSv/(Gy.cm2) for the physician and 4.1+/-8.7 MUSv/(Gy.cm2) for the instrumentalist nurse. The results indicate that the eye lens to chest dose ratio greatly varies according to the staff function and that the dose equivalent measured by the personal dosimeter worn on the chest may underestimate the eye lens dose of some medical staff members. PMID- 29195558 TI - Comprehensive clinical commissioning and validation of the RayStation treatment planning system for proton therapy with active scanning and passive treatment techniques. AB - PURPOSE: To commission the treatment planning system (TPS) RayStation for proton therapy including beam models for spot scanning and for uniform scanning. METHODS: Tests consist of procedures from ESTRO booklet number 7, the German DIN for constancy checks of TPSs, and extra tests checking the dose perturbation function. The dose distributions within patients were verified in silico by a comparison of 65 clinical treatment plans with the TPS XiO. Dose-volume parameters, dose differences, and three-dimensional gamma-indices serve as measures of similarity. The monthly constancy checks of Raystation have been automatized with a script. RESULTS: The basic functionality of the software complies with ESTRO booklet number 7. For a few features minor enhancements are suggested. The dose distribution in RayStation agrees with the calculation in XiO. This is supported by a gamma-index (3mm/3%) pass rate of >98.9% (median over 59 plans) for the volume within the 20% isodose line and a difference of <0.3% of V95 of the PTV (median over 59 plans). If spot scanning is used together with a range shifter, the dose level calculated by RayStation can be off by a few percent. CONCLUSIONS: RayStation can be used for the creation of clinical proton treatment plans. Compared to XiO RayStation has an improved modelling of the lateral dose fall-off in passively delivered fields. For spot scanning fields with range shifter blocks an empirical adjustment of monitor units is required. The computation of perturbed doses also allows the evaluation of the robustness of a treatment plan. PMID- 29195559 TI - Phase-contrast imaging for body composition measurement. AB - PURPOSE: In this paper, we propose a novel method for human body composition measurement, especially for the bone mineral density (BMD) measurement. The proposed method, using the absorption and differential phase information retrieved from X-ray grating-based interferometer (XGBI) to measure the BMD, has potential to replace dual-energy X-ray absorptiometry (DEXA), which is currently widely used for body composition measurement. METHODS: The DEXA method employs two absorption images acquired at two different X-ray spectra (high energy and low energy) to calculate the human body composition. In this paper, a new method to calculate BMD using a single X-ray measurement is proposed. XGBI is a relatively new X-ray technique that provides absorption, phase and scattering information simultaneously using a single X-ray spectrum. With the absorption and differential phase information retrieved from XGBI, BMD can be measured using only one single X-ray spectrum. Numerical simulations are performed with a body phantom of bone (Cortical, ICRU-44) surrounded by soft tissue (Soft, ICRU-44). BMD is calculated with both the DEXA method and the proposed method. RESULTS: Results show that BMD can be measured accurately with the proposed method; moreover, better signal-to-noise ratio (SNR) is obtained compared to DEXA. CONCLUSION: With the proposed method, BMD can be measured with XGBI setup. Further, the proposed method can be realized using current X-ray phase-contrast imaging (XPCI) apparatus without any hardware modification, suggesting that this technique can be a promising supplementary function to current XPCI equipment. PMID- 29195560 TI - gammaTools: A modular multifunction phantom for quality assurance in GammaKnife treatments. AB - PURPOSE: We present the gammaTools, a new phantom designed to assess geometric and dosimetric accuracy in Gamma Knife treatments, together with first tests and results of applications. METHODS: The phantom is composed of two modules: the imaging module, a regular grid of 1660 control points to evaluate image distortions and image registration result and the dosimetry module for delivered dose distribution measurements. The phantom is accompanied by a MatLab routine for image distortions quantification. Dose measurement are performed with Gafchromic films fixed between two inserts and placed in various positions and orientations inside the dosimetry module thus covering a volume comparable to the full volume of a head. RESULTS: Tests performed to assess the accuracy and precision of the imaging module demonstrated sub-millimetric values. As an example of possible applications, the phantom was employed to measure image distortions of two MRI scanners and to perform dosimetric studies of single shots delivered to homogeneous and heterogeneous materials. Due to the phantom material, the measured absolute dose do not correspond to the planned dose; doses comparisons are thus carried out between normalized dose distributions. Finally, an end-to-end test was carried out in the treatment of a neuroma-like target which resulted in a 100% gamma passing rate (2% local, 2 mm) and a distance between the real target perimeter and the prescription isodose centroids of about 1 mm. CONCLUSIONS: The tests demonstrate that the proposed phantom is suitable to assess both the geometrical and relative dosimetric accuracy of Gamma Knife radiosurgery treatments. PMID- 29195561 TI - Dose accumulation of multiple high dose rate prostate brachytherapy treatments in two commercially available image registration systems. AB - PURPOSE: The purpose of this study was to assess whether deformable image registration (DIR) is required for dose accumulation of multiple high dose rate prostate brachytherapy (HDRPBT) plans treated with the same catheter pattern on two different CT datasets. METHOD: DIR was applied to 20 HDRPBT patients' planning CT images who received two treatment fractions on sequential days, on two different CT datasets, with the same implant. Quality of DIR in Velocity and MIM image registration systems was assessed by calculating the Dice Similarity Coefficient (DSC) and mean distance to agreement (MDA) for the prostate, urethra and rectum contours. Accumulated doses from each system were then calculated using the same DIR technique and dose volume histogram (DVH) parameters compared to manual addition with no DIR. RESULTS: The average DSC was found to be 0.83 (Velocity) and 0.84 (MIM), 0.80 (Velocity) and 0.80 (MIM), 0.80 (Velocity) and 0.81 (MIM), for the prostate, rectum and urethra contours, respectively. The average difference in calculated DVH parameters between the two systems using dose accumulation was less than 1%, and there was no statistically significant difference found between deformably accumulated doses in the two systems versus manual DVH addition with no DIR. CONCLUSION: Contour propagation using DIR in velocity and MIM was shown to be at least equivalent to inter-observer contouring variability on CT. The results also indicate that dose accumulation through manual addition of DVH parameters may be sufficient for HDRPBT treatments treated with the same catheter pattern on two different CT datasets. PMID- 29195562 TI - Abdominal imaging dose in radiology and radiotherapy - Phantom point dose measurements, effective dose and secondary cancer risk. AB - PURPOSE: To compare abdominal imaging dose from 3D imaging in radiology (standard/low-dose/dual-energy CT) and radiotherapy (planning CT, kV cone-beam CT (CBCT)). METHODS: Dose was measured by thermoluminescent dosimeters (TLD's) placed at 86 positions in an anthropomorphic phantom. Point, organ and effective dose were assessed, and secondary cancer risk from imaging was estimated. RESULTS: Overall dose and mean organ dose comparisons yield significantly lower dose for the optimized radiology protocols (dual-source and care kV), with an average dose of 0.34+/-0.01 mGy and 0.54+/-0.01 mGy (average +/- standard deviation), respectively. Standard abdominal CT and planning CT involve considerably higher dose (13.58 +/- 0.18 mGy and 18.78+/-0.27 mGy, respectively). The CBCT dose show a dose fall-off near the field edges. On average, dose is reduced as compared with the planning or standard CT (3.79 +/- 0.21 mGy for 220 degrees rotation and 7.76 +/- 0.37 mGy for 360 degrees ), unless the high quality setting is chosen (20.30 +/- 0.96 mGy). The mean organ doses show a similar behavior, which translates to the estimated secondary cancer risk. The modelled risk is in the range between 0.4 cases per million patient years (PY) for the radiological scans dual-energy and care kV, and 300 cases per million PY for the high-quality CBCT setting. CONCLUSIONS: Modern radiotherapy imaging techniques (while much lower in dose than radiotherapy), involve considerably more dose to the patient than modern radiology techniques. Given the frequency of radiotherapy imaging, a further reduction in radiotherapy imaging dose appears to be both desirable and technically feasible. PMID- 29195563 TI - Awareness of medical radiation exposure among patients: A patient survey as a first step for effective communication of ionizing radiation risks. AB - INTRODUCTION: The European Directive 2013/59/EURATOM requires patient radiation dose information to be included in the medical report of radiological procedures. To provide effective communication to the patient, it is necessary to first assess the patient's level of knowledge regarding medical exposure. The goal of this work is to survey patients' current knowledge level of both medical exposure to ionizing radiation and professional disciplines and communication means used by patients to garner information. MATERIAL AND METHODS: A questionnaire was designed comprised of thirteen questions: 737 patients participated in the survey. The data were analysed based on population age, education, and number of radiological procedures received in the three years prior to survey. RESULTS: A majority of respondents (56.4%) did not know which modality uses ionizing radiation. 74.7% had never discussed with healthcare professionals the risk concerning their medical radiological procedures. 70.1% were not aware of the professionals that have expertise to discuss the use of ionizing radiation for medical purposes, and 84.7% believe it is important to have the radiation dose information stated in the medical report. CONCLUSION: Patients agree with new regulations that it is important to know the radiation level related to the medical exposure, but there is little awareness in terms of which modalities use X-Rays and the professionals and channels that can help them to better understand the exposure information. To plan effective communication, it is essential to devise methods and adequate resources for key professionals (medical physicists, radiologists, referring physicians) to convey correct and effective information. PMID- 29195564 TI - Adapted estimate of neural activity based on blood-oxygen-level dependent signal by a model-free spatio-temporal clustering analysis. AB - In this study, we detected brain activity by comparing the overall temporal response of the blood oxygen level referring to hemodynamic response with a modeled hemodynamic response (MHR). However, in a conventional analysis by statistical parametric mapping (SPM) method, the MHR is assumed to be a fixed response function, which may bias the conclusions about brain activation, such as the shapes of the response curve or the different response delays to stimuli. Therefore, to improve detection efficacy, we applied a spatio-temporal clustering analysis (sTCA) to determine the MHR, which is calculated from the prospective voxels with no a priori information about the experiment design. With the sTCA method, these prospective voxels are detected by the feature with the largest temporal clustering within which these voxels react simultaneously, irrespective of where the variant hemodynamic response occurs. This estimated MHR (eMHR) is then applied to search for brain activation. Preliminary results show that the eMHR signal response closely resembles the real signal response of the target area. Moreover, the activation detection using eMHR method is more sensitive for the human visual and motor tasks than that with the canonical hemodynamic response embedded in the SPM analysis as the default MHR (dMHR). The more precise location of brain activation made possible by the improved sensitivity should provide helpful information about the stimulation of neuron activity. PMID- 29195565 TI - Usefulness of a new online patient-specific quality assurance system for respiratory-gated radiotherapy. AB - PURPOSE: The accuracy of gated irradiation may decrease when treatment is performed with short "beam-on" times. Also, the dose is subject to variation between treatment sessions if the respiratory rate is irregular. We therefore evaluated the impact of the differences between gated and non-gated treatment on doses using a new online quality assurance (QA) system for respiratory-gated radiotherapy. METHODS: We generated dose estimation models to associate dose and pulse information using a 0.6 cc Farmer chamber and our QA system. During gated irradiation with each of seven regular and irregular respiratory patterns, with the Farmer chamber readings as references, we evaluated our QA system's accuracy. We then used the QA system to assess the impact of respiratory patterns on dose distribution for three lung and three liver radiotherapy plans. Gated and non gated plans were generated and compared. RESULTS: There was agreement within 1.7% between the ionization chamber and our system for several regular and irregular motion patterns. For dose distributions with measured errors, there were larger differences between gated and non-gated treatment for high-dose regions within the planned treatment volume (PTV). Compared with a non-gated plan, PTV D95% for a gated plan decreased by -1.5% to -2.6%. Doses to organs at risk were similar with both plans. CONCLUSIONS: Our simple system estimated the radiation dose to the patient using only pulse information from the linac, even during irregular respiration. The quality of gated irradiation for each patient can be verified fraction by fraction. PMID- 29195566 TI - Radiotherapy for non-malignant shoulder syndrome: Is there a risk for radiation induced carcinogenesis? AB - PURPOSE: To estimate the organ-specific probability for carcinogenesis following radiotherapy for non-malignant shoulder syndrome. METHODS: Photon-beam radiation therapy to 6 Gy for shoulder syndrome was simulated with a Monte Carlo code. An androgynous computational phantom representing a typical adult was used to calculate the radiation dose to out-of-field organs having a predilection for carcinogenesis. The organ-specific lifetime attributable risk (LAR) for out-of field cancer induction was estimated by the organ dose calculations and the proper risk factors introduced by the BEIR-VII report. The average dose (Dav) and organ equivalent dose (OED) of lung, which was partially included within the treatment volume, was found from 3d-conformal radiotherapy plans. The Dav and OED were used to estimate the lung cancer risk with a linear and mechanistic models, respectively. All risk assessments were made for 50- and 60-year-old male and female patients. RESULTS: Monte Carlo simulations resulted in an out-of-field organ dose range of 0.7-48.4 mGy. The LARs for out-of-field cancer induction were (1.4 * 10-4)% to (2.8 * 10-2)%. These probabilities were at least 403 times lower than the respective lifetime intrinsic risk (LIR) values. The Dav and OED of lung was up to 164.9 and 142.3 mGy, respectively. The LAR for developing lung malignancies varied from 0.11 to 0.18% by the model used and the patient's age and gender. The lung cancer risks were 36-64 times smaller than the LIRs. CONCLUSIONS: The estimated probabilities for developing malignancies due to radiotherapy for non-malignant shoulder syndrome are minor relative to the natural cancer occurrence rates.

AB - In the last few years, the use of ions in radiation therapy is gaining interest and it is being considered medically necessary for a growing subset of tumours. Concurrently, the technologies involved in a particle therapy treatment are rapidly evolving, as well as the accuracy in the dose delivery in spite of the increased complexity. Since nowadays, the pencil beam scanning technique is showing very interesting features in terms of dose conformation and overall treatment outcome, the present review is intended to summarize the main procedures, detectors and tools adopted for the clinical dose verification. A list of dose measurements is provided, with the aim of being a valuable guidance for starting and future particle therapy facilities. Absorbed dose to water, relative dose, fluence and surrogates of the delivered dose are the main quantities measured by means of different detectors, specifically developed for point-like, 1D or 2D measurements. The dosimetric procedures are here categorized according to their purpose, distinguishing between system commissioning and clinical quality assurance. A separate discussion is dedicated to patient specific, in vivo and 4D dose verification, which aim at assessing the actual delivered dose. Together with the description of the currently used methods, challenges and perspectives toward an increasingly accurate and fast dose verification strategy are discussed. PMID- 29195568 TI - Editorial. PMID- 29195570 TI - Worldwide Trends in Multi-arterial Coronary Artery Bypass Grafting Surgery 2004 2014: A Tale of 2 Continents. AB - Recent evidence shows that multi-arterial coronary artery bypass grafting (MABG) based on bilateral internal thoracic (BITA) or left internal thoracic (LITA) and radial artery (RA) improves long-term outcomes compared with single arterial coronary artery bypass grafting (SABG) (LITA + saphenous vein graft). How this evidence affected the worldwide use of MABG, if at all, is not well defined. Accordingly, we report 10-year temporal trends of MABG utilization from 2 continents. A study population of 1,683,434 non-emergent, primary, isolated LITA based coronary artery bypass grafting (CABG) (>=2 grafts) patients was derived from the Society of Thoracic Surgeons (STS) (1,307,528 (79.5%) of 1,644,388 isolated CABG; total 1179 centers) and the Australia New Zealand Cardiothoracic (ANZ) Databases (34,213 (87%) of 39,046 isolated CABG; 24 centers) between 2004 and 2014. Patients were excluded based on the following: (1) no LITA, (2) if arterial grafts were other than RA or ITA, or (3) if grafting data were missing. The 3 MABG groups were LITA + RA, BITA, and BITA + RA, each with or without supplemental vein grafts. Grafting trends and their associated patient demographics were analyzed. SABG (89.3% STS, 51.4% ANZ) was the most common grafting strategy. MABG was most frequently accomplished by LITA + RA: (STS: 6.1%; ANZ: 42.6%), followed by BITA: (STS: 4.1%; ANZ: 4.3%), while >=3 (BITA + RA) was rare in the STS (0.5%), but more common in ANZ (5.9%). In the STS, between 2004 and 2014, SABG rates systematically increased from 85.2% to 91.7%, BITA grafting was essentially unchanged from 3.6% to 4.3%, while RA use decreased systematically from 10.5% to 3.7%. In the ANZ, SABG rates increased from 17.3% to 51.4%, BITA grafting decreased from 6.3% to 3.6%, while RA grafting decreased from 65.8% to 39.0%. Compared with SABG patients, BITA patients were younger (STS: median age 59 vs 66, P < 0.001; ANZ: mean age 62 vs 68, P < 0.001), predominately male (STS: 84% vs 73%, P < 0.001; ANZ: 86% vs 79%, P < 0.001), less obese (body mass index >30 kg/m2) in STS (37% vs 42%, P < 0.001), more obese in ANZ (33% vs 32%, P = 0.001), and less diabetic (STS: 26% vs 43%, P < 0.001; ANZ: 25% vs 37%, P < 0.001), whereas RA patients were intermediate in age (STS: 61; ANZ: 65), in male sex (STS: 82%; ANZ: 81%), in the prevalence of diabetes (STS: 40%; ANZ: 34%), and were most obese (STS: 47%; ANZ: 34%). A decade-long analysis of STS data reveals a counterintuitive decline in the use (driven by decreasing RA use) of MABG: a potentially superior grafting strategy compared with SABG. In contra distinction, the smaller but growing ANZ data document a distinctly different CABG practice pattern, with a higher MABG utilization rate, but a similarly declining RA use. The reasons for these practice patterns and declining MABG are likely diverse and require further assessment. PMID- 29195571 TI - Impact of Discordant Views in the Management of Descending Thoracic Aortic Aneurysm. AB - Thoracic endovascular aortic repair has a lower perceived risk than open surgical repair and has become an increasingly popular alternative. Whether general consensus exists regarding candidacy for either operation among open and endovascular specialists is unknown. A retrospective review of isolated descending thoracic aortic aneurysm at our institution between January 2005 and October 2015 was performed, excluding trauma and dissection. Two cardiac surgeons, 2 cardiovascular surgeons, 1 vascular surgeon, and 1 interventional radiologist gave their preference for open vs endovascular repair. Interobserver agreement was assessed with the kappa coefficient. k-means clustering agnostically grouped various patterns of agreement. The mean rating was predicted using least absolute shrinkage and selection operator regression. Negative binomial regression predicted the discrepancy between our panel of raters and the historical operation. Generalized estimating equation modeling was then used to evaluate the association between the extent of discrepancy and the adverse perioperative outcome. There were 77 patients with preoperative imaging studies. Pairwise interobserver agreement was only fair (median weighted kappa 0.270 [interquartile range 0.211-0.404]). Increasing age and proximal neck length predicted an increasing preference for thoracic endovascular aortic repair in our panel; larger proximal neck diameter predicted a general preference for open surgical repair. Increasing proximal neck diameter predicted a larger discrepancy between our panel and the historical operation. Greater discrepancy was associated with adverse outcome. Substantial disagreement existed among our panel, and an exploratory analysis of the effect of increasing discrepancy demonstrated an association with adverse perioperative outcome. An investigation of the effect of a thoracic aortic team with open and endovascular specialists is warranted. PMID- 29195572 TI - Carbon Dioxide Insufflation During Cardiac Surgery: A Meta-analysis of Randomized Controlled Trials. AB - Despite the widespread use of carbon dioxide insufflation (CDI) in cardiac surgery, there is still paucity of evidence to prove its benefit in terms of neurologic protection. Therefore, we conducted a meta-analysis of available randomized controlled trials comparing CDI vs standard de-airing maneuvers. Electronic searches were performed to identify relevant randomized controlled trials. Primary outcomes investigated were postoperative stroke, neurocognitive deterioration, and in-hospital mortality. Risk difference (RD) was used as summary statistic. Pooled estimates were obtained by means of random-effects model to account for possible clinical diversity and methodological variation between studies. Eight studies were identified with 668 patients randomized to CDI (n = 332) vs standard de-airing maneuvers (n = 336). In-hospital mortality was 2.1% vs 3.0% in the CDI and control group, respectively (RD 0%; 95% confidence interval [CI] -2% to 2%; P = 0.87; I2 = 0%). Incidence of stroke was similar between the 2 groups (1.0% vs 1.2% in the CDI and control group, respectively; RD 0%; 95% CI -1% to 2%; P = 0.62; I2 = 0%). Neurocognitive deterioration rate was 12% vs 21% in the CDI and control group, respectively, but this difference was not statistically significant (RD: -7%; 95% CI -0.22% to 8%; P = 0.35; I2 = 0%). The present meta-analysis did not find any significant protective effect from the use of CDI when compared with manual de-airing maneuvers in terms of clinical outcomes, including postoperative neurocognitive decline. PMID- 29195573 TI - Complications After Self-expanding Transcatheter or Surgical Aortic Valve Replacement. AB - Procedural complications following transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) are usually reported as retrospective analyses. We report the first comparison of complications following SAVR or self expanding TAVR from a prospectively randomized study of high-risk SAVR patients. Three hundred ninety-five TAVR and 402 SAVR patients were prospectively enrolled and randomized 1:1 to TAVR with a CoreValve bioprosthesis or a surgical bioprosthetic valve. The rates of major procedural and vascular complications occurring (periprocedurally (0-3 days) and early (4-30 days)) were compared for TAVR vs SAVR patients. All-cause mortality, stroke, myocardial infarction, and major infection were similar in both periods post procedure. Within 0-3 days, the major vascular complication rate was significantly higher with TAVR (P = 0.003). Life-threatening or disabling bleeding (P < 0.001), encephalopathy (P = 0.02), atrial fibrillation (P < 0.001), and acute kidney injury (P < 0.001) were significantly higher with SAVR. Non-iliofemoral TAVR approaches had a higher incidence of major or life-threatening or disabling bleeding at 0-3days (P < 0.05). Procedural complications unique to TAVR included coronary occlusion 0.5% (2) and TAVR pop outs 2.8% (11) with no valve embolizations. Pop outs were similar between iliofemoral 2.8% (9/324) and non-iliofemoral approaches 3.0% (2/66). Procedural complications unique to SAVR included aortic dissection 0.8% (3/357) and injury to other heart structures 2.0% (7/357). The procedural complication profiles of TAVR and SAVR are unique. Intraoperative deaths were seen in TAVR only. Mortality at 3 and 30 days was similar. The higher incidence of some complications likely reflects the greater invasiveness of SAVR in this aged high-risk population. PMID- 29195574 TI - Outcomes of Surgery for Mixed Total Anomalous Pulmonary Venous Drainage in Children. AB - Total anomalous pulmonary venous drainage (TAPVD) is an uncommon cardiac defect in children. The mixed subset accounts for 5%-10% of the TAPVD and is variable in its anatomy. The outcomes associated with this subset of patients are rarely reported. A retrospective review of all patients with mixed TAPVD undergoing repair at a single institution (1984-2014) was conducted. A descriptive analysis was performed. Twenty-four patients underwent repair for mixed TAPVD (6 univentricular physiology, 18 biventricular physiology). The mixed TAPVD anatomy included 8 patients in group I (2 + 2 veins), 11 patients in group II (3 + 1 veins), and 5 patients in group III (atypical). Preoperative pulmonary venous obstruction occurred in 8 patients (33%). The median age at repair was 2.2 months (range 2 days to 3 years) and median weight was 4.2 kg (range 1.9 to 12.5 kg). Operative mortality was 13% (3 of 24), 33.3% (2 of 6) for patients with univentricular physiology, and 5.6% (1 of 18) for patients with biventricular physiology. There have been no operative deaths in the biventricular group since 1997 (n = 11). Survival at 30-days was 83% +/- 15% (95% confidence interval: 27% 97%) and 94% +/- 5% (95% confidence interval: 67%-99%) for the univentricular and biventricular groups, respectively. Reoperation for recurrent pulmonary venous obstruction was required in 2 patients (8.3%) where the sutureless technique was used. The average follow-up after surgery was 9.3 +/- 6.4 years (5 months to 21 years), and all surviving patients were asymptomatic. Mixed TAPVD can be repaired with good results in children, particularly in those undergoing biventricular repair. PMID- 29195575 TI - Twenty-Five Year Outcomes of the Lateral Tunnel Fontan Procedure. AB - The objective of this study was to characterize late outcomes of the lateral tunnel (LT) Fontan procedure. The outcomes of all patients who underwent an LT Fontan procedure in Australia and in New Zealand were analyzed. Original files were reviewed and outcomes data were obtained through a binational registry. Between 1980 and 2014, a total of 301 patients underwent an LT Fontan procedure across 6 major centers. There were 13 hospital mortalities, 21 late deaths, 8 Fontan conversions and revisions, 8 Fontan takedowns, and 4 heart transplantations. Overall survival at 15 and 25 years was 90% (95% confidence interval [CI]: 86%-93%) and 80% (95% CI: 69%-91%), respectively. Protein-losing enteropathy or plastic bronchitis was observed in 14 patients (5%). Freedom from late failure at 15 and 25 years was 88% (95% CI: 84%-92%) and 82% (95% CI: 76% 87%), respectively. Independent predictors of late Fontan failure were prolonged pleural effusions post Fontan operations (hazard ratio [HR] 3.06, 1.05-8.95, P = 0.041), age >7 years at Fontan (vs 3-5 years, HR 9.7, 2.46-38.21, P = 0.001) and development of supraventricular tachycardia (HR 4.67, 2.07-10.58, P < 0.001). Freedom from tachy- or bradyarrhythmias at 10 and 20 years was 87% (95% CI: 83% 91%) and 72% (95% CI: 66%-79%), respectively. Thromboembolic events occurred in 45 patients (16%, 26 strokes), and freedom from symptomatic thromboembolism at 10 and 20 years was 93% (95% CI: 89%-96%) and 80% (95% CI: 74%-86%), respectively. Over a 25-year period, the LT technique has achieved excellent late survival. As this population ages, it is at an increasing risk of failure and adverse events. We are likely to see an increasing proportion requiring heart transplantation and late reintervention. PMID- 29195576 TI - Histologic Evaluation of Explanted Tissue-Engineered Bovine Pericardium (CardioCel). AB - CardioCel is a bovine pericardium that is subjected to a novel anticalcification tissue-engineering process. We present the histopathologic findings of human explants of CardioCel that were used in operations for congenital heart disease in children. Six explants were identified from 140 patients undergoing CardioCel implants from October 2012 to March 2015. CardioCel explants were evaluated histologically using hematoxylin and eosin, Masson trichrome, and immunohistochemical staining. A variable inflammatory response was seen in the surrounding native tissue, but not within the CardioCel graft in any of the explants. A neointimal layer of varying thickness developed on the visceral surface of 5 CardioCel explants with endothelialization of the longest duration explant. A granulation tissue layer developed on the parietal surface of the graft (consistently thicker than the neointima). Maintained collagen fiber architecture (laminated) and variable fibroblastic invasion (which increased with the age of the implant) were identified in all 6 cases. Scattered capillary vessels were noted in the majority of the explants with new collagen fibers in one, suggesting early remodeling. Calcium was seen in 1 explant at the interface of the graft and inflammatory response on its parietal surface. Evidence of graft remodeling was noted in the majority of the explants without inflammatory cells or calcification within the explanted graft material. A noticeable feature was the differential thickness of the host reaction to the parietal compared with the visceral surface of the graft. We will continue to evaluate CardioCel as a cardiovascular substitute for extracardiac and intracardiac reconstructions. PMID- 29195577 TI - Perspectives on Managing Solitary Pulmonary Nodules: A Survey of Primary Care Physicians. AB - Primary care physicians (PCPs) may be involved in the evaluation of solitary pulmonary nodules (SPNs) detected through lung cancer screening. Little is known about their perspectives on the management or the referral of SPN. Using the American Medical Association's Physician Masterfile, we randomly surveyed 1384 PCPs between January and October 2015 with an 18% response rate. A subset analysis was performed on SPN management and referral practices of PCP. These results and those relating to practice characteristics were compared between family practice and internal medicine physicians. Responders and nonresponders did not differ by demographic characteristics. A total of 137 (55.5%) PCPs reported feeling confident in managing the workup of imaging-detected SPN. However, only 53 PCPs (21.3%) were inclined to manage the evaluation and follow up of SPN. There was no significant difference between family practice and internal medicine physicians with regard to years in practice, size of practice, or referral to specialists. Family practitioners and internists similarly disagreed or were neutral to self-managing SPN (P = 0.60). Internists were twice as likely to express confidence as family practitioners (odds ratio 1.95, 95% confidence interval 1.09-3.48). Among all PCPs, 75.4% would refer management of these patients to a pulmonologist, 28.9% to a surgeon, and 24.2% to an oncologist. Confidence did not predict lung cancer screening practices. Although more than half of PCPs expressed confidence in the workup of SPN, most preferred referral to specialists. Additional research is needed to understand barriers to PCP management of incidental SPN in the effort to facilitate lung cancer screening.

LMS of the great vessels accounts for 60% of cases, with inferior vena cava being the most common site. Pulmonary vein LMS is an extremely rare subset that was first reported in 1939. LMS is an aggressive tumor, making surgical resection the treatment of choice. Herein, we present a rare case of pulmonary vein LMS extending into the left atrium, which was resected. PMID- 29195578 TI - Programmed Death Cell Ligand 1 (PD-L1) Is Associated With Survival in Stage I Non Small Cell Lung Cancer. AB - Programmed cell death ligand (PD-L1) has been studied as a predictive immunotherapy biomarker. We investigated PD-L1 expression in the whole tumor and in tumor-infiltrating macrophages (TIMs) as a prognostic biomarker in surgically resected pathologic stage I non-small cell lung cancer. Pathologic specimen from 113 patients with stage I lung cancer (pT1-2a, N0, M0, tumor size 1-5 cm, 79 adenocarcinoma, 34 squamous cell carcinoma) were analyzed for PD-L1 expression in the tumor and in the TIMs using immunohistochemistry and image analysis. Statistics included recursive partitioning, univariable, multivariable, and Kaplan-Meier analyses. Patients whose tumors expressed <4.7% PD-L1 (N = 87) experienced significantly better overall survival (OS) (P = 0.001) than patients with PD-L1 >4.7% (N = 26). Patients with PD-L1 expression in macrophages <6.3% (N = 24) also experienced significantly better (P = 0.005) OS than patients with >6.3% (N = 89). The best outcomes were observed in patients with low PD-L1 expression in both tumor and macrophages with 5-year OS of 94% (N = 17). Contrarily, patients with high PD-L1 expression in both tumor and macrophages experienced 5-year OS of 20% (N = 19). Low PD-L1 expression in the tumor and in the TIMs was independently associated with survival in multivariable analysis (P = 0.000 and P = 0.030, respectively). Lower PD-L1 % expression in the tumor and in the TIMs seems to be associated with significantly better OS in surgically resected stage I lung cancer. Additional studies are needed to validate PD-L1 as a prognostic biomarker in lung cancer and to study the mechanisms of intratumoral immune response.

PMID- 29195582 TI - Microbial profile and characterization of blue bulb manual suction devices used to promote airway clearance in newborns in intrapartum and postpartum units. AB - BACKGROUND: Newborns are suctioned with a blue bulb manual suction device to remove naso-oropharyngeal secretions and promote airway clearance. This study identifies and discusses the microbial profile and characterization of the bulb used in newborns on intrapartum and postpartum units. METHODS: This was a descriptive study with convenience sampling of a total of 50 bulbs used in cesarean births, vaginal births, and on the postpartum unit. The bulbs were tested for microbial growth, and the percentages of contaminated bulbs were calculated. The chi2 test was used to compare the proportion of bulbs with microbial growth by route of birth among bulbs sampled from the intrapartum unit. RESULTS: Microbial profile and characterization identified a total of 57 different gram-positive cocci and rods and gram-negative rods. Among 50 bulbs cultured, bacterial growth was present in 42% of the bulbs, and Escherichia coli was identified in 55% of the gram-negative rod isolates. The chi2 test comparing vaginal and cesarean bulbs showed a statistically significant difference in the percentages of contaminated bulbs for any growth (P = .023) and for any Staphylococcus spp (P = .050). CONCLUSIONS: New empirical evidence confirms the bulb is a potential bacterial reservoir and poses a potential health risk for nosocomial infections for newborns. Further studies are needed to identify bacterial transmission, newborn outcomes, bactericidal bulb cleaning methods, and quality and safe suction practices. PMID- 29195583 TI - Risk factors for methicillin-resistant Staphylococcus aureus colonization in the neonatal intensive care unit: A systematic review and meta-analysis. AB - CONTEXT: Methicillin-resistant Staphylococcus aureus (MRSA) causes a significant burden of illness in neonatal intensive care units (NICUs) worldwide. Identifying infants colonized with MRSA has become an important infection control strategy to interrupt nosocomial transmission. OBJECTIVE: Assess risk factors for MRSA colonization in NICUs via a systematic review and meta-analysis. DATA SOURCES: MEDLINE, Embase, Web of Science, and The Cochrane Library databases were searched from inception through September 2015. STUDY SELECTION: Studies reporting risk factors for MRSA colonization using noncolonized controls in subspecialty level III or IV NICUs were included. DATA EXTRACTION: Two authors independently extracted data on MRSA colonization risk factors, study design, and MRSA screening methodology. RESULTS: Eleven articles were included in the systematic review, with 10 articles analyzed via meta-analysis. MRSA colonization was associated with gestational age <32 weeks (odds ratio [OR], 2.67; 95% confidence interval [CI], 1.35-5.27; P = .01) and birth weight <1,500 g (OR, 2.63; 95% CI, 1.25-5.55; P = .01). Infant sex (P = .21), race (P = .06), inborn status (P = .09), and delivery type (P = .24) were not significantly associated with colonization. CONCLUSIONS: Very preterm and very-low birth weight infants were identified as having an increased risk for MRSA colonization on meta-analysis. Multifaceted infection prevention strategies should target these high-risk infants to reduce MRSA colonization rates in NICUs. PMID- 29195584 TI - Health care-associated infections studies project: An American Journal of Infection Control and National Healthcare Safety Network data quality collaboration. AB - This case study is part of a series centered on the Centers for Disease Control and Prevention/National Healthcare Safety Network (NHSN) health care-associated infection (HAI) surveillance definitions. This specific case study focuses on the definitions and protocols used to make HAI infection determinations, such as the infection window period and secondary bloodstream infection attribution period. The case reflects the real-life and complex patient scenarios that infection preventionists (IPs) face when identifying and reporting HAIs to NHSN. The intent of the case study series is to foster standardized application of the NHSN HAI surveillance definitions among IPs and encourage accurate determination of HAI events. An online survey link is provided where participants may confidentially answer questions related to the case study and receive immediate feedback in the form of correct answers and explanations and rationales. Details of the case study, answers, and explanations have been reviewed and approved by NHSN staff. We hope that participants take advantage of this educational offering and thereby gain a greater understanding of NHSN HAI surveillance definitions.

PMID- 29195588 TI - Characteristics and clinical treatment of tobacco smokers enrolled in a VA substance use disorders clinic. AB - Individuals with a substance use disorder (SUD) diagnosis are more than twice as likely to smoke cigarettes as the general population. Emerging research has suggested that treating a substance use disorder simultaneously with tobacco use leads to a higher rate of treatment success for both substances. Despite this, substance use treatment protocols tend not to focus on tobacco use; in fact, traditional substance use treatments often discourage patients from attempting to quit smoking. One rationale is that patients may not be motivated to quit smoking. In the current study, data from veterans enrolled in outpatient treatment for a SUD were examined to assess for general characteristics of smokers as compared to non-smokers as well as to examine motivation to quit smoking. Baseline (i.e., pre-treatment) data from 277 Veterans were used. Charts of smokers in the SUD clinic (SUDC) were reviewed to assess how smoking is handled by SUDC providers, and if smokers attempt cessation. Of 277, 163 (59%) SUDC patients reported that they currently smoke cigarettes (M=16.3 cigarettes per day, SD=11.1). Smokers in the clinic reported greater general impairment than nonsmokers on the Short Index of Problems, F(1248)=8.9, p=0.003, as well as greater specific impairment: Physical Problems, F(1258)=13.5, p=0.000; Interpersonal Problems, F(1262)=5.6, p=0.019; Intrapersonal Problems, F(1260)=6.5, p=0.011, and Social Responsibility, F(1262)=14.7, p=0.000. Smokers in the sample were marginally more anxious than their non-smoking counterparts as measured by the GAD-7, F(1254)=4.6, p=0.053, though they were not significantly more depressed (p=0.19). On a 1-10 scale, smokers reported moderate levels of importance (M=5.4, SD=3.1), readiness (M=5.6, SD=3.2), and confidence (M=5.0, SD=3.0) regarding quitting smoking. Review of smokers' medical records reveal that while SUDC providers assess tobacco use at intake (90%) and offer treatment (86.5%), a substantially small portion of smokers attempt cessation (41.1%) while enrolled in SUDC. Moreover, no patients were enrolled in smoking-specific behavioral interventions while in SUDC, though 78 patients did obtain nicotine replacement or another smoking cessation medication (41% were prescribed by a SUDC provider). Contrary to the belief that treatment-seeking substance users are not motivated to quit smoking, these preliminary analyses demonstrate that Veterans were at least contemplating quitting smoking while they were enrolled in substance use treatment. Further, there is evidence that cigarette smokers have greater impairment caused by substance use, suggesting that this subgroup is of particular high need. Specific treatment recommendations are discussed, including how behavioral health providers in SUD clinics may be better able to capitalize on patients' moderate motivation to quit at intake. PMID- 29195589 TI - Factors associated with naloxone administration in an opioid dependent sample. AB - INTRODUCTION: Naloxone is a safe and effective antidote for reversing opioid overdose. Layperson administration of naloxone is increasingly common, yet little is known about demographic and clinical factors associated with opioid users' likelihood of having administered naloxone to another opioid user who had overdosed. We examined predictors of reported naloxone administration in the past year. METHODS: Four hundred and sixty-eight patients were interviewed upon admission to brief, inpatient opioid detoxification between May and December of 2015. Between group differences were tested using t-tests for differences in means and chi2-tests for differences in counts. RESULTS: Participants averaged 32years of age, 28.9% were female, and 86.8% were White. Most (86.8%) reported detoxifying from heroin, 69.0% had injected drugs in the last 30days. One sixth (n=68) of those detoxifying from heroin, but none of those detoxifying from other opioids (n=62) had administered naloxone in the past year. Among the small number of Black/African American participants (n=20), none had administered naloxone, although 90% were heroin users. Respondents were more likely to have administered naloxone if they reported recent injection drug use (IDU), had a history of overdose, or witnessed an overdose in the past year (ps<0.05), even though less than one-third of bystanders of overdose reported administering naloxone. CONCLUSIONS: Higher opioid-related mortality risk (heroin use, IDU, past overdose) was associated with greater likelihood of reported naloxone administration in the past year. The non-use of naloxone among certain groups prescription pill users and Blacks-was unexpected. PMID- 29195590 TI - Age differences in outcomes among patients in the "Stimulant Abuser Groups to Engage in 12-Step" (STAGE-12) intervention. AB - : Emerging adults (roughly 18-29years) with substance use disorders can benefit from participation in twelve-step mutual-help organizations (TSMHO), however their attendance and participation in such groups is relatively low. Twelve-step facilitation therapies, such as the Stimulant Abuser Groups to Engage in 12-Step (STAGE-12), may increase attendance and involvement, and lead to decreased substance use. AIMS: Analyses examined whether age moderated the STAGE-12 effects on substance use and TSMHO meeting attendance and participation. DESIGN: We utilized data from a multisite randomized controlled trial, with assessments at baseline, mid-treatment (week 4), end-of-treatment (week 8), and 3- and 6- months post-randomization. PARTICIPANTS: Participants were adults with DSM-IV diagnosed stimulant abuse or dependence (N=450) enrolling in 10 intensive outpatient substance use treatment programs across the U.S. ANALYSIS: A zero-inflated negative binomial random-effects regression model was utilized to examine age-by treatment interactions on substance use and meeting attendance and involvement. FINDINGS: Younger age was associated with larger treatment effects for stimulant use. Specifically, younger age was associated with greater odds of remaining abstinent from stimulants in STAGE-12 versus Treatment-as-Usual; however, among those who were not abstinent during treatment, younger age was related to greater rates of stimulant use at follow-up for those in STAGE-12 compared to TAU. There was no main effect of age on stimulant use. Younger age was also related to somewhat greater active involvement in different types of TSMHO activities among those in STAGE-12 versus TAU. There were no age-by-treatment interactions for other types of substance use or for treatment attendance, however, in contrast to stimulant use; younger age was associated with lower odds of abstinence from non stimulant drugs at follow-up, regardless of treatment condition. These results suggest that STAGE-12 can be beneficial for some emerging adults with stimulant use disorder, and ongoing assessment of continued use is of particular importance. PMID- 29195591 TI - Variability in motivational interviewing adherence across sessions, providers, sites, and research contexts. AB - Providers' adherence in the delivery of behavioral interventions for substance use disorders is not fixed, but instead can vary across sessions, providers, and intervention sites. This variability can substantially impact the quality of intervention that clients receive. However, there has been limited work to systematically evaluate the extent to which substance use intervention adherence varies from session-to-session, provider-to-provider, and site-to-site. The present study quantifies the extent to which adherence to Motivational Interviewing (MI) for alcohol and drug use varies across sessions, providers, and intervention sites and compares the extent of this variability across three common MI research contexts that evaluate MI efficacy, MI effectiveness, and MI training. Independent raters coded intervention adherence to MI from 1275 sessions delivered by 216 providers at 15 intervention sites. Multilevel models indicated that 57%-94% of the variance in MI adherence was attributable to variability between sessions (i.e., within providers), while smaller proportions of variance were attributable to variability between providers (3%-26%) and between intervention sites (0.1%-28%). MI adherence was typically lowest and most variable within contexts evaluating MI training (i.e., where MI was not protocol guided and delivered by community treatment providers) and, conversely, adherence was typically highest and least variable in contexts evaluating MI efficacy and effectiveness (i.e., where MI was highly protocolized and delivered by trained therapists). These results suggest that MI adherence in efficacy and effectiveness trials may be substantially different from that obtained in community treatment settings, where adherence is likely to be far more heterogeneous. PMID- 29195592 TI - Understanding abuse of buprenorphine/naloxone film versus tablet products using data from ASI-MV(r) substance use disorder treatment centers and RADARS(r) System Poison Centers. AB - OBJECTIVES: The objectives were to examine the abuse prevalence and route-of administration (ROA) profiles of sublingual buprenorphine/naloxone combination (BNX) film in comparison with the BNX tablet and to identify clinically-relevant subgroups of patients or geographic patterns. METHODS: Between Q1 2015 through Q3 2015, data were collected from two major surveillance systems: (1) assessment of individuals in substance use disorder (SUD) treatment collected from the National Addictions Vigilance Intervention and Prevention Program (NAVIPPRO(r)) ASI-MV(r) system and (2) intentional abuse/misuse exposures in the RADARS(r) System Poison Center Program. Poisson regression models were tailored to each system's data characteristics by population (all SUD treatment patients, US census) and adjusted for prescription volume. Effects of gender, race, age and US region as well as ROA profile were examined. RESULTS: For the ASI-MV study, 45,695 assessments of unique adults evaluated for substance use problems were collected. The abuse rate unadjusted for prescription volume of BNX tablet formulation was 2.64 cases/100 ASI-MV respondents versus 7.01 cases for the film formulation (RR=0.390, p<0.001). Prescription-adjusted abuse, however, was greater for the tablet version (0.47 abuse cases/100 ASI-MV respondents/100,000 dosage units compared with 0.38 for the film) (RR=1.25, p<0.001). Results among the US population from the RADARS System Poison Center Program data revealed a similar pattern; population rates for film abuse (0.0364) were greater than for tablet (0.0161), while prescription-adjusted rates were greater for tablet (0.2114) than for film (0.1703) per 100,000 prescriptions. ASI-MV ROA analyses indicated less abuse of the film by any alternate route, insufflation or injection than the tablet. Poison center data found more injection of tablets than film, although insufflation was not significantly different. CONCLUSIONS: On a prescription adjusted basis, overall abuse of the BNX tablet is greater than that of the sublingual film formulation. For those who continue to abuse BNX, use by alternate ROAs was, in general, lower for the film. PMID- 29195594 TI - Duration of therapy - Does it matter?: A systematic review and meta-regression of the duration of psychosocial treatments for alcohol use disorder. AB - BACKGROUND: The recommendations in clinical guidelines for duration of therapy for alcohol use disorder (AUD) are based on consensus decisions. In reality, we do not know the optimal duration of an alcohol treatment course. METHODS: A systematic review and meta-regression of randomized controlled trials of psychosocial treatment in alcohol outpatient treatment centers. The population consisted of adults suffering from AUD, treated in an outpatient facility with at least two sessions of therapy. Meta-regression analysis was performed with treatment outcome as a function of duration of therapy across studies. Treatment outcome was defined as long-term alcohol use measured in percentage of days abstinent (PDA), percentage of heavy days drinking (PHD), and/or proportion of participants abstinent (ABS). RESULTS: 48 studies encompassing 8984 participants. Mean planned duration of therapy: 18 (8-82) weeks and 14 (2-36) sessions. Mean actual attended sessions: 9 (1-26). Mean follow-up time: 43 (8-104) weeks with a mean of 6 (2-18) research assessments. Neither planned weeks, duration of sessions, frequency of sessions per week, nor actual attended sessions were associated with long-term alcohol use outcomes. However, frequency of research assessments was positively associated with PDA and PHD. CONCLUSION: No associations between long-term alcohol use outcomes and planned or actual attended duration of psychosocial treatment in outpatient care. Research assessments and, accordingly, the research project in itself may influence outcome in studies of psychosocial treatment for alcohol use disorder. PMID- 29195593 TI - Gender and ethnic differences in primary care patients' response to computerized vs. in-person brief intervention for illicit drug misuse. AB - This study is a secondary analysis from a randomized clinical trial of computerized vs. in-person brief intervention (BI) for illicit drug misuse among adult primary care patients (N=359; 45% Female; 47% Hispanic) with moderate-risk illicit drug misuse as measured by the World Health Organization's Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST). This study examined differences in response to the two brief intervention strategies (both based on motivational interviewing) on the basis of gender and ethnicity, comparing non Hispanic males, non-Hispanic females, Hispanic males, and Hispanic females. Participants were assessed at baseline, 3-, 6-, and 12-month follow-up with the ASSIST. Trajectories in Global Continuum of Illicit Drug Risk Scores were examined using a generalized linear mixed model. There were significant differences in response to computerized vs. in-person BI over time on the basis of gender-ethnic subgroups (Gender*Ethnicity*Condition*Time interaction; p=0.03), with Hispanic males tending to respond more favorably to the computerized BI and Hispanic females tending to respond more favorably to the in-person BI. There was no clear differentiation in response to the two BIs among non-Hispanic males, while among non-Hispanic females the pattern of change converged following baseline differences. Consideration of gender and ethnic differences in future studies of BI is warranted. PMID- 29195596 TI - Group-based treatment of opioid use disorder with buprenorphine: A systematic review. AB - BACKGROUND: Opioid use disorder (OUD) has become a public health crisis in the U.S., and there is a need to develop effective clinical treatment strategies. Coupling buprenorphine/naloxone (B/N) maintenance with counseling is encouraged as a best practice, yet the efficacy research on individual counseling in B/N based Office-Based Opioid Treatment (OBOT) has been equivocal to date. In contrast, models for integrating B/N prescribing through group-based counseling could potentially have a differential impact, yet no systematic reviews have focused on examining the extent of the literature on group-based models of B/N delivery. METHODS: We conducted a systematic literature review to identify existing studies characterizing the different formats of Group-Based Opioid Treatment (GBOT), which we defined as the coupling of B/N prescribing with required office-based group counseling. Using this definition of GBOT, B/N prescribing could occur either concurrently during a medical visit with group counseling (i.e., Shared Medical Appointment) or asynchronously (i.e., Group Psychotherapy). We assessed for all available scientific literature reporting on the feasibility, acceptability and/or efficacy of these different forms of GBOT. The systematic review protocol used PRISMA standards. RESULTS: We included 10 peer-reviewed, full-text articles and 5 conference abstracts of office-based opioid use disorder treatment that reported data on the feasibility, acceptability, and efficacy of Group-Based Opioid Treatment with B/N. Of the ten full-text articles we included 4 studies describing a shared medical appointment (SMA) model and 6 studies describing a group psychotherapy model. Of these studies, all were low in quality due to study design and only three were randomized controlled trials. No studies were appropriately designed to rigorously compare the efficacy of a GBOT approach (i.e., B/N prescribing with required group-based counseling) versus B/N prescribing with required individual counseling; nor were they designed for rigorous comparison with medication management alone. Nevertheless, most studies reported on the feasibility and acceptability of various models representative of a GBOT approach. CONCLUSION: The small number of studies and study design limited the conclusions that could be drawn about the feasibility, acceptability, and efficacy of group-based B/N treatment. More research is needed to determine whether benefits exist of GBOT with B/N. PMID- 29195595 TI - Factors associated with victimization in dual diagnosis patients. AB - BACKGROUND: Patients with a substance use disorder and co-occurring mental disorder are prone to victimization. There is a lack of research identifying variables related to violent and property victimization in this high risk group. The aim of this study was to identify factors associated with violent and property victimization in male and female dual diagnosis patients in order to identify targets for prevention. METHODS: In a cross-sectional study, victimization and demographic, clinical and psychological characteristics were assessed in 243 treatment-seeking patients with dual diagnosis. Patients were recruited in an addiction-psychiatry clinic and an allied outpatient care facility in Amsterdam, The Netherlands. RESULTS: In a multiple logistic regression analysis, violent victimization was independently associated with younger age, female gender, violent offending and a self-sacrificing and overly accommodating interpersonal style (p<0.001; chi2=108.83, d.f.=8, R2=0.49) in dual diagnosis patients. In male patients, violent victimization was independently associated with younger age, violent offending and a self-sacrificing and overly accommodating interpersonal style (p<0.001; chi2=91.90, d.f.=7, R2=0.56). In female patients, violent victimization was independently positively associated with homelessness, violent offending, a domineering/controlling interpersonal style, and negatively associated with being socially inhibited and cold/distant (p<0.001; chi2=34.08, d.f.=4, R2=0.53). Property victimization was independently associated with theft offending (p<0.001, chi2=26.99, d.f.=5, R2=0.14). CONCLUSIONS: Given the high prevalence of victimization in dual diagnosis patients and its related problems, preventive interventions should be developed. Interventions should target interpersonal skills to decrease vulnerability to victimization, address the overlap between victimization and offending and incorporate gender-specific elements. PMID- 29195597 TI - Organizational Readiness for Change (ORC) test used in the implementation of assessment instruments and treatment methods in a Swedish National study. AB - : Organizational climate and related factors are associated with outcome and are as such of vital interest for healthcare organizations. Organizational Readiness for Change (ORC) is the questionnaire used in the present study to assess the influence of organizational factors on implementation success. The respondents were employed in one of 203 Swedish municipalities within social work and psychiatric substance/abuse treatment services. They took part in a nationwide implementation project organized by the Swedish Association of Local Authorities and Regions (SALAR), commissioned by the Swedish National Board of Health and Welfare. AIM: The aims were: (a) to identify classes (clusters) of employees with different ORC profiles on the basis of data collected in 2011 and (b) to investigate ORC profiles which predicted the use of assessment instruments, therapy methods and collaborative activities in 2011 and 2013. DESIGN AND RECRUITMENT: The evaluation study applied a naturalistic design with registration of outcome at consecutive assessments. The participants were contacted via official e-mail addresses in their respective healthcare units and were encouraged by their officials to participate on a voluntary basis. STATISTICS: Descriptive statistics were obtained using SPSS version 23. A latent profile analysis (LPA) using Mplus 7.3 was performed with a robust maximum likelihood estimator (MLR) to identify subgroups (clusters) based on the 18 ORC indexes. RESULTS: A total of 2402 employees responded to the survey, of whom 1794 (74.7%) completed the ORC scores. Descriptive analysis indicated that the respondents were a homogenous group of employees, where women (72.0%) formed the majority. Cronbach's alpha for the 18 ORC indexes ranged from alpha=0.67 to alpha=0.78. A principal component analysis yielded a four-factor solution explaining 62% of the variance in total ORC scores. The factors were: motivational readiness (alpha=0.64), institutional resources (alpha=0.52), staff attributes (alpha=0.76), and organizational climate (alpha=0.74). An LPA analysis of the four factors with their three distinct profiles provided the best data fit: Profile 3 (n=614), Profile 2 (n=934), and Profile 1 (n=246). Respondents with the most favorable ORC scores (Profile 3) used significantly more instruments and more treatment methods and had a better collaborating network in 2011 as well as in 2013 compared to members in Profile 1, the least successful profile. CONCLUSION: In a large sample of social work and healthcare professionals, ORC scores reflecting higher institutional resources, staff attributes and organizational climate and lower motivational readiness for change were associated with a successful implementation of good practice guidelines for the care and treatment of substance users in Sweden. Low motivational readiness as a construct may indicate satisfaction with the present situation. As ORC proved to be an indicator of successful dissemination of evidence-based guidelines into routine and specialist healthcare, it can be used to tailor interventions to individual employees or services and to improve the dissemination of and compliance with guidelines for the treatment of substance users.

PMID- 29195602 TI - Reduction of body iron in HFE-related haemochromatosis and moderate iron overload (Mi-Iron): a multicentre, participant-blinded, randomised controlled trial. AB - BACKGROUND: The iron overload disorder hereditary haemochromatosis is most commonly caused by HFE p.Cys282Tyr homozygosity. In the absence of results from any randomised trials, current evidence is insufficient to determine whether individuals with hereditary haemochromatosis and moderately elevated serum ferritin, should undergo iron reduction treatment. This trial aimed to establish whether serum ferritin normalisation in this population improved symptoms and surrogate biomarkers. METHODS: This study was a multicentre, participant-blinded, randomised controlled trial done at three centres in Australia. We enrolled people who were homozygous for HFE p.Cys282Tyr, aged between 18 and 70 years, with moderately elevated serum ferritin, defined as 300-1000 MUg/L, and raised transferrin saturation. Participants were randomly assigned, via a computer generated random number, to undergo either iron reduction by erythrocytapheresis (treatment group) or sham treatment by plasmapheresis (control group). Randomisation was stratified by baseline serum ferritin (<600 MUg/L or >=600 MUg/L), sex, and study site. Erythrocytapheresis and plasmapheresis were done every 3 weeks, the number of procedures and volume of red cells or plasma removed determined on the basis of each patient's haemoglobin, haematocrit, and serum ferritin concentration, as well their height and weight. In the erythrocytapheresis group, the target was to reduce serum ferritin to less than 300 MUg/L. The number of procedures for the control group was based on the initial serum ferritin and prediction of decrease in serum ferritin of approximately 120 MUg/L per treatment. The primary outcome was patient-reported Modified Fatigue Impact Scale (MFIS) score, measured at baseline and before unblinding. Analyses were by intention to treat, including the safety analysis. The trial is registered with ClinicalTrials.gov, number NCT01631708, and has been completed. FINDINGS: Between Aug 15, 2012, and June 9, 2016, 104 participants were randomly assigned to the treatment (n=54) and control (n=50) groups, of whom 94 completed the study (50 in the treatment group and 44 in the control group). Improvement in MFIS score was greater in the treatment group than in the control group (mean difference -6.3, 95% CI -11.1 to -1.4, p=0.013). There was a significant difference in the cognitive subcomponent (-3.6, -5.9 to -1.3, p=0.0030), but not in the physical (-1.90 -4.5 to 0.63, p=0.14) and psychosocial (-0.54, -1.2 to 0.11, p=0.10) subcomponents. No serious adverse events occurred in either group. One participant in the control group had a vasovagal event and 17 participants (14 in the treatment group and three in the control group) had transient symptoms assessed as related to hypovolaemia. Mild citrate reactions were more common in the treatment group (32 events [25%] in 129 procedures) compared with the control group (one event [1%] in 93 procedures). INTERPRETATION: To our knowledge, this study is the first to objectively assess the consequences of iron removal in individuals with hereditary haemochromatosis and moderately elevated serum ferritin. Our results suggest that serum ferritin normalisation by iron depletion could be of benefit for all individuals with hereditary haemochromatosis and elevated serum ferritin levels.

AB - In the present article, the authors reviewed the rationale of FDG-PET/CT performed at an interim time point during therapy (iPET), focusing on the transition from standard, anatomical assessment of tumor shrinkage with CT to document a chemotherapy response, to the use of functional imaging with PET to assess chemosensitivity of the individual tumor. The prognostic or predictive role of iPET in different lymphoma subsets has been reviewed, with particular emphasis on early and advanced-stage Hodgkin lymphoma, diffuse large B-cell lymphoma, peripheral T-cell lymphoma, extranodal natural killer/T-cell lymphoma, and primary mediastinal B-cell lymphoma. A large body of evidence exists in most lymphoma subtypes stressing the role of iPET for early chemotherapy response during first-line chemotherapy treatment, but an increased number of reports have recently been published focusing on the role of iPET in relapsed or refractory lymphoma to predict treatment outcome. Varying patterns of FDG uptake was observed across various lymphoma entities; hence, interpretation of FDG-PET scans should be in the context of the tumor architecture and the prevalence of cellular population, in particular, neoplastic vs non-neoplastic inflammatory cells present in tissue microenvironment. In the second part of the article, the authors reviewed the iPET-response adapted clinical trials and the clinical benefits of this strategy compared to standard non-PET adapted therapy. In particular, the authors extrapolated the reproducibility of FDG-PET image interpretation and the feasibility of a timely treatment adaptation based on FDG PET results in daily clinical practice. This is essential for the reader, as the iPET-adapted strategy has become the standard of care in both early- and advanced stage Hodgkin lymphoma, and, in the future, probably this strategy will be expanded to primary mediastinal B-cell lymphoma, follicular lymphoma, and peripheral T-cell lymphoma. PMID- 29195614 TI - Guest Editorial. PMID- 29195615 TI - PET/CT for Lymphoma Post-therapy Response Assessment in Hodgkin Lymphoma and Diffuse Large B-cell Lymphoma. AB - Over the course of many decades, combined chemotherapy and radiotherapy adapted to the stage of disease have become the optimal and standard treatment for Hodgkin lymphoma (HL) and diffuse large B-cell lymphoma. Besides achieving optimized cure rates of the underlying disease, reduction of toxicity has become a major goal. Since the introduction of FDG-PET for the staging and restaging of patients with lymphoma, a high predictive value of F-18-FDG-PET in response assessment has been observed. Several PET-response-guided therapy regimens have already been established, and even more PET-adapted study designs are being tested in large study groups. PET has a very high negative predictive value following chemotherapy, and radiotherapy can be safely omitted in PET-negative patients with HL after effective chemotherapy with regimens such as bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone in advanced stages. As "state-of-the-art" PET-guided therapy is based on the results of large clinical trials, the reliability of end-of-treatment PET as a basis for abandoning radiotherapy in early and intermediate HL stages remains to be shown. As in HL, the predictive value of FDG-PET after induction therapy of diffuse large B-cell lymphoma is higher than that of CT alone so that we obtain relevant prognostic information unavailable through anatomical imaging. Recent results from trials in aggressive non-HL with a de-escalating strategy suggest that radiotherapy may be safely omitted if FDG-PET is negative after standard chemoimmunotherapy. Since 2007, FDG-PET at end of treatment is integrated into the International Working Group criteria and became the imaging tool of choice for response assessment in aggressive lymphoma. Robust and reproducible interpretation criteria are being used both in the ongoing clinical trials and in daily routine. The recommended five-point scale has become the standard in PET response assessment, with the caveat that the consequence of a PET scan may be influenced by foregoing and following treatments. PMID- 29195616 TI - PET/CT for Lymphoma Post-therapy Response Assessment in Other Lymphomas, Response Assessment for Autologous Stem Cell Transplant, and Lymphoma Follow-up. AB - FDG-PET/CT is an established first-line diagnostic imaging tool used in the staging of most lymphomas and for post-therapy response assessment in Hodgkin lymphoma (HL) and diffuse large B-cell lymphoma (DLBCL). Many of the subtypes of lymphoid neoplasms classified by the World Health Organization demonstrate significant FDG-avidity or uptake; however, many guidelines and Lugano classification do not recommend the use of FDG-PET/CT in assessing response to therapy for these non-HL, non-DLBCL subtypes as a first-line diagnostic tool. This article reviews the role of FDG-PET/CT in the evaluation of the other most common "FDG-avid" lymphomas than HL and DLBCL, the role of FDG-PET/CT before autologous stem cell transplant, and for post-treatment follow-up. Follicular lymphoma is most commonly FDG-avid with a wide range of uptake that generally correlates with the histologic grade, a major determinant of aggressiveness and prognosis. FDG-PET/CT is more sensitive and specific than CT for detecting residual disease post therapy for both aggressive and indolent follicular lymphoma. Post-treatment FDG-PET/CT for follicular lymphoma has significant prognostic value, that is, better predicts progression-free and overall survival than does conventional post-treatment assessment with CT. FDG-PET/CT is useful in the staging of mantle cell lymphoma, a very aggressive, incurable subtype of lymphoma; however, data show mixed results on the benefits of FDG-PET/CT over conventional CT assessment in post-therapy response evaluation. Peripheral T-cell lymphomas, a rare aggressive group of T-cell lymphomas, are often FDG-avid. Post therapy FDG-PET/CT results have major prognostic value and therapeutic implications in many subtypes of peripheral T-cell lymphomas. Post-treatment FDG PET/CT is superior to conventional CT for determining chemosensitivity of lymphoma, and therefore is better able to predict which patients will have a greater benefit or outcome with autologous stem cell transplant. There are mixed data on the value of FDG-PET/CT for surveillance after treatment because of high reported false-positive rates and accuracy that depends on the duration or timing of surveillance and the subtype of lymphoma. PMID- 29195617 TI - PET/CT for Staging; Past, Present, and Future. AB - Accurate and reproducible staging is crucial for management of malignant lymphomas. Disease stage influences treatment decisions more significantly than any other clinical information in most lymphoma subtypes, and contributes with important prognostic information on its own or as part of clinical prognostic scores. Information derived from medical imaging is the single most important determinant of disease stage, and the introduction PET/CT for lymphoma has led to substantial changes in the concept as well as practice of lymphoma staging. Over time, the most important change in lymphoma staging has been the abandonment of extensive pathologic staging intended in the original Ann Arbor classification. The 2014 Lugano Classification represents the most recent expert recommendation for staging of lymphoma. This revision recognizes the improved diagnostic accuracy of PET/CT over stand-alone CT and recommended PET/CT for routine staging of all FDG-avid lymphomas. Routine bone marrow biopsies are also discouraged in Hodgkin lymphoma as well as in selected cases of diffuse large B-cell lymphoma. The scope of this review is to give the reader insight into the history of staging, the purpose of lymphoma staging in the context of contemporary treatment strategies, and the advantages of PET/CT staging over conventional staging. We also discuss the controversies of PET/CT replacing conventional bone marrow biopsies in different lymphoma subtypes and summarize recommendations by the recent Lugano classification. PMID- 29195618 TI - Metabolic Tumor Volume Metrics in Lymphoma. AB - Although visual assessment using the Deauville criteria is strongly recommended by guidelines for treatment response monitoring in all FDG-avid lymphoma histologies, the high rate of false-positives and concerns about interobserver variability have motivated the development of quantitative tools to facilitate objective measurement of tumor response in both routine and clinical trial settings. Imaging studies using functional quantitative measures play a significant role in profiling oncologic processes. These quantitative metrics allow for objective end points in multicenter clinical trials. However, the standardization of imaging procedures including image acquisition parameters, reconstruction and analytic measures, and validation of these methods are essential to enable an individualized treatment approach. A robust quality control program associated with the inclusion of proper scanner calibration, cross-calibration with dose calibrators and across other scanners is required for accurate quantitative measurements. In this section, we will review the technical and methodological considerations related to PET-derived quantitative metrics and the relevant published data to emphasize the potential value of these metrics in the prediction of patient prognosis in lymphoma. PMID- 29195619 TI - PET/CT in Radiation Therapy Planning. AB - Radiation therapy (RT) is an important component of the management of lymphoma patients. Most lymphomas are metabolically active and accumulate 18F fluorodeoxyglucose (FDG). Positron emission tomography with computer tomography (PET/CT) imaging using FDG is used routinely in staging and treatment evaluation. FDG-PET/CT imaging is now also used routinely for contouring the target for RT, and has been shown to change the irradiated volume significantly compared with CT imaging alone. Modern advanced imaging techniques with image fusion and motion management in combination with modern highly conformal RT techniques have increased the precision of RT, and have made it possible to reduce dramatically the risks of long-term side effects of treatment while maintaining the high cure rates for these diseases. PMID- 29195620 TI - PET/CT in Lymphoma: Current Overview and Future Directions. AB - Over the past several decades, PET has emerged as critical to accurate staging and restaging of lymphomas. Nonetheless, a number of critical issues regarding its optimal use remain. Whereas risk-adapted strategies appear to improve the outcome of patients with Hodgkin lymphoma, results are less convincing in non Hodgkin lymphoma. Assessment of metabolic tumor volume before treatment may permit novel induction strategies. New drugs that may induce an immune response may result in a false-positive FDG/PET scan, mandating modifications of current criteria to consider tumor flare reactions. Application of PET may be improved by integration of biomarker studies and a better understanding of the role of the microenvironment. Methods to improve the integration of FDG/PET enhance its role in the management of patients with lymphoma, leading to improved patient outcome.

PMID- 29195623 TI - Clinical utility of self-disclosure for adults who stutter: Apologetic versus informative statements. AB - PURPOSE: The purpose of the present study was to explore the clinical utility of self-disclosure, particularly, whether disclosing in an informative manner would result in more positive observer ratings of the speaker who stutters than either disclosing in an apologetic manner or choosing not to self-disclose at all. METHOD: Observers (N=338) were randomly assigned to view one of six possible videos (i.e., adult male informative self-disclosure, adult male apologetic self disclosure, adult male no self-disclosure, adult female informative self disclosure, adult female apologetic self-disclosure, adult female no self disclosure). Observers completed a survey assessing their perceptions of the speaker they viewed immediately after watching the video. RESULTS: Results suggest that self-disclosing in an informative manner leads to significantly more positive observer ratings than choosing not to self-disclose. In contrast, use of an apologetic statement, for the most part, does not yield significantly more positive ratings than choosing not to self-disclose. CONCLUSION: Clinicians should recommend their clients self-disclose in an informative manner to facilitate more positive observer perceptions. PMID- 29195624 TI - Self-efficacy and quality of life in adults who stutter. AB - PURPOSE: Self-efficacy has emerged as a potential predictor of quality of life for adults who stutter. Research has focused primarily on the positive relationship self-efficacy has to treatment outcomes, but little is known about the relationship between self-efficacy and quality of life for adults who stutter. The purpose of this mixed- methods study is to determine the predictive value of self-efficacy and its relationship to quality of life for adults who stutter. METHOD: The Self-Efficacy Scale for Adult Stutterers and the Overall Assessment of the Speaker's Experience with Stuttering were administered to 39 adults who stutter, aged 18- 77. Percentage of syllables stuttered was calculated from a conversational speech sample as a measure of stuttered speech frequency. Qualitative interviews with semi-structured probes were conducted with 10 adults and analyzed using thematic analysis to explore the lived experience of adults who stutter. RESULTS: Self-efficacy emerged as a strong positive predictor of quality of life for adults living with a stuttered speech disorder. Stuttered speech frequency was a moderate negative predictor of self-efficacy. Major qualitative themes identified from the interviews with the participants were: encumbrance, self-concept, confidence, acceptance, life-long journey, treatment, and support. CONCLUSION: Results provide clarity on the predictive value of self efficacy and its relationship to quality of life and stuttered speech frequency. Findings highlight that the unique life experiences of adults who stutter require a multidimensional approach to the assessment and treatment of stuttered speech disorders.

AB - PURPOSE: This groundbreaking research compares the experience of stuttering among adult male People Who Stutter (PWS) from the ultra-Orthodox (UO) Jewish community in Israel to those from Secular/Traditional (ST) backgrounds. METHODS: Participants were 32 UO and 31 ST PWS, aged 18-67 years. Self-report questionnaires utilized: Perceived Stuttering Severity (PSS); Overall Assessment of the Speaker's Experience of Stuttering (OASES-A); Students' Life Satisfaction Scale (SLSS); Situation Avoidance Behavior Checklist (SABC). Demographic, religious, and stuttering information was collected. Groups were compared on scales, and correlations between scales and the PSS. RESULTS: Subjective stuttering severity ratings were significantly higher among the UO. A significant group effect was found for the OASES-A quality of life subscale, but not other subscales. Significant positive correlations were found between: 1) PSS and OASES A Total Impact; 2) PSS and 3 OASES subscales; and 3) PSS and SABC (indicating increased avoidance with increased stuttering severity rating). A significant negative correlation was found between the PSS and SLSS, indicating lower life satisfaction with higher rates of stuttering severity among the ST. Interestingly, when tested by group, significant correlations between the PSS and all other study measures were observed only among the ST. CONCLUSION: UO participants showed higher subjective stuttering severity ratings, yet less impact on quality of life, and no correlation between subjective stuttering and other measures of stuttering experience. These novel findings may result from the combined protective effect of religiosity and socio-cultural characteristics on UO PWS' well-being, despite heightened concern about social consequences of stuttering within UO society.

PMID- 29195627 TI - Ethyl pyruvate is renoprotective against ischemia-reperfusion injury under hyperglycemia. AB - BACKGROUND: Hyperglycemia (HG) is common in cardiovascular surgeries due to diabetes, inflammation, and the neuroendocrine stress response. HG aggravates renal ischemia-reperfusion (I/R) injury through an increased inflammatory response, and blunts the protective effect of various measures. Ethyl pyruvate (EP) provides anti-inflammatory effects against I/R injury via inhibition of high mobility group box 1 protein (HMGB1) release. This study aimed to determine the renoprotective effect of EP against I/R injury under HG. METHODS: Sprague-Dawley rats were randomly assigned at random to 8 groups: normoglycemia (NG)-sham, NG I/R-control, NG-EP-I/R (pretreatment), NG-I/R-EP (posttreatment), HG-sham, HG-I/R control, HG-EP-I/R, and HG-I/R-EP. Renal I/R was induced by 45 minutes of ischemia (clamping of renal arteries), followed by 24 hours of reperfusion. EP (50 mg/kg) was administered intraperitoneally at 1 h before ischemia (pretreatment) or on reperfusion (posttreatment). RESULTS: I/R injury under HG significantly aggravated the degree of renal tubular apoptosis and damage compared with the NG groups, which could be attenuated by both pretreatment and posttreatment of EP. I/R-induced increases in HMGB1 and Toll-like receptors (TLRs), activation of NF-kB, and resultant alterations in interleukin-1beta, tumor necrosis factor-alpha, proapoptotic Bax, and antiapoptotic Bcl-2 were all favorably modulated by EP treatment in both the NG and HG groups compared with their corresponding control groups. CONCLUSIONS: Despite aggravation of renal I/R injury by HG through amplified inflammation, EP administration showed similar suppression of the HMGB1-TLR-NF-kB pathway in the HG and NG groups. EP retained anti-inflammatory, antiapoptotic, and renoprotective effects in the HG groups, whether administered before ischemia or on reperfusion.

AB - Expansion of newborn screening programmes increases the complexity around reproductive choices, both in terms of the increased number of parents faced with making reproductive decisions from the earliest days of their affected child's life, and the number of conditions for which such decisions have to be made. We conducted a scoping review to explore: (i) reproductive decision-making among parents of children with recessive genetic conditions; and, (ii) the involvement of healthcare services in facilitating and supporting those decisions. Systematic search processes involved seven bibliographic databases, citation, and grey literature searches. From an initial total of 311 identified articles, seven met the inclusion criteria and were included in the review. The extracted data were organised around three themes: factors influencing reproductive decisions taken by parents, how those factors changed over time, and the involvement of healthcare services in supporting and facilitating reproductive decisions. Most studies focused on attitudes towards, and uptake of, pre-natal diagnosis (PND) and termination. None of the studies considered the wider range of reproductive choices facing all parents, including those of children with conditions for whom PND and termination is not available or where good health outcomes make these options less justifiable. The literature provided little insight into the role of healthcare staff in providing family planning support for these parents. There is a need to better understand the support parents need in their decision-making, and who is best placed to provide that support.

AB - Select estimates of contraceptive use in the 2015-16 National Family Health Survey (NFHS is equivalent to the Demographic and Health Survey in India) have come under the scrutiny of researchers and policy makers globally. Using four waves (1992-93, 1998-99, 2005-06, and 2015-16) of published NFHS reports, this article aims to highlight the change in Contraceptive Prevalence Rate (CPR) and initiate a discussion to help investigate the reasons for the recent decline of CPR. PMID- 29195630 TI - Influence of intimate partner violence during pregnancy on fear of childbirth. AB - OBJECTIVE: Women are at increased risk of intimate partner violence (IPV) during pregnancy. This may impact women's positive anticipation for birth. Negative feelings around birth often translate to a fear of childbirth. Our aim was to examine the prevalence IPV and whether physical, sexual, psychological IPV during pregnancy predicts fear of childbirth among Iranian pregnant women. METHOD: A population-based cross sectional study was conducted in North-East Iran. Pregnant women (n=174) at least 14weeks gestation attending health centers were selected for inclusion through a stratified sampling method. IPV, fear of birth, state and trait anxiety and socio-demographic variables were collected using validated instruments. To achieve the final models the Bayesian information criterion was used. A p value of <0.05 was considered statistically significant. RESULTS: Seventy-three percent of women reported experiencing IPV at least once within their current pregnancy. Fear of birth was prevalent (61.5%). Logistic regression analysis revealed that after adjusting for confounding factors, in nulliparous physical IPV significantly predicted fear of birth (adjusted OR=12.15; 95% CI, 1.33, 110.96) while, in multiparous psychological IPV associated inversely with fear of birth (adjusted OR=0.18; 95% CI, 0.04, 0.73). For all participants, physical IPV increased the chance of fear of birth, (adjusted OR=2.47; 95% CI, 1.01, 6.02). CONCLUSION: All pregnant women experiencing physical violence had a higher chance of fear of birth. Screening programs for fear of birth and IPV need to be implemented in particular for nulliparous women. Providing continuity of midwifery care and family therapy may be strategies for early support to reduce IPV to pregnant women. PMID- 29195631 TI - Preconception health care interventions: A scoping review. AB - Pregnancy is often framed as a "window of opportunity" for intervening on a variety of health practices such as alcohol and tobacco use. However, there is evidence that interventions focusing solely on the time of pregnancy can be too narrow and potentially stigmatizing. Indeed, health risks observed in the preconception period often continue during pregnancy. Using a scoping review methodology, this study consolidates knowledge and information related to current preconception and interconception health care interventions published in the academic literature. We identified a total of 29 intervention evaluations, and summarized these narratively. Findings suggest that there has been some progress in intervening on preconception health, with the majority of interventions offering assessment or screening followed by brief intervention or counselling. Overall, these interventions demonstrated improvements in at least some of the outcomes measured. However, further preconception care research and intervention design is needed. In particular, the integration of gender transformative principles into preconception care is needed, along with further intervention design for partners/ men, and more investigation on how best to deliver preconception care. PMID- 29195632 TI - Parents' involvement in the human papillomavirus vaccination decision for their sons. AB - OBJECTIVES: Parents are critical to ensure sufficient human papillomavirus (HPV) vaccine coverage. No studies to date have examined how mothers and fathers perceive their own, their partners' and their sons' involvement in HPV vaccination decision-making process. METHODS: An online survey methodology was used to collect data from a national sample of Canadian parents (33% fathers, 67% mothers, Mage=44) who had a 9-16years old son (n=3117). MAIN OUTCOME MEASURES: Parent's perception of their self-involvement, partner-involvement and son's involvement in the decision to get their son the HPV vaccine were measured on a Likert scale and were classified as 'no involvement', 'moderate involvement' and 'high involvement'. RESULTS: Mothers and fathers both perceive that they themselves and their partners should be highly involved in their son's HPV vaccination decision. Son's involvement was reported as moderate and influenced by age. Significant gender differences were found for self and partner involvement, but the effect sizes were small. CONCLUSION: Mothers and fathers both perceive that they themselves and their partners should be significantly involved in their son's HPV vaccination decision. A dyad decision-making model involving both parents for HPV vaccine decision-making is suggested with a stronger recommendation for a triad decision-making model involving both parents as well as the child/adolescent. Gender stereotypes of females perceiving themselves as the sole decision-maker or fathers not wanting to be involved in their children's health decision were not supported. PMID- 29195633 TI - Effects of women's autonomy on maternal healthcare utilization in Bangladesh: Evidence from a national survey. AB - OBJECTIVES: This study aims to construct an index of women's autonomy to analyze its effect on maternal healthcare utilization in Bangladesh. Empirical modeling of the study used instrumental variable (IV) approach to correct for possible endogeneity of women's autonomy variable. METHODS: Data from the Bangladesh Demographic and Health Survey (BDHS) 2011 was used for the study. Women's autonomy variable was obtained through factor analysis of variables related to autonomy in decision making regarding healthcare, financial autonomy and freedom of movement. Conditional mixed process (CMP) models were fitted for three maternal healthcare indicators: at least four antenatal care (ANC) by trained personnel, institutional delivery and postnatal care (PNC) by trained personnel. RESULTS: Study sample consisted of 8753 women with 5.5 mean years of schooling. Women with no formal education, of Islamic faith, from poorest wealth quintile, residing in rural areas and with low autonomy used the maternal healthcare least. Marginal effect shows that if women's autonomy score is increased by one unit, probability of maternal healthcare utilization will increase by 0.14 for ANC, 0.14 for institutional delivery, and 0.13 for PNC. CONCLUSIONS: Women's autonomy is an important driver of maternal healthcare utilization in Bangladesh. Results suggest that women participating in social and economic activities enhances their autonomy. Other factors affecting women's autonomy are female literacy, educational attainment and households' economic status. PMID- 29195634 TI - Choice of contraceptive methods by women's status: Evidence from large-scale microdata in Nepal. AB - OBJECTIVE: We aimed to investigate how improvement in women's status affects the choice of contraceptive methods in Nepal. STUDY DESIGN: We regressed the choice of contraceptive methods on women's status and other controlling variables by employing large-scale microdata representing over 12,000 married women aged 15-49 years in Nepal. Years of schooling and literacy were defined as women's status variables. We estimated how educational attainment affects the choice of contraceptive methods. We also analyzed how fear of their partners affected women's choices. RESULTS: Female sterilization was the most common choice among the contraceptive methods (25.5% of contraceptive users) in Nepal, followed by injections (19.9%). However, our estimation results showed that these options change with an improvement in women's status. An additional year of education increased the probability that women would choose condoms by 1.2 percentage points (95% confidence interval [CI]: 0.7, 1.6) and decreased the probability of choosing female sterilization by 1.4 percentage points (95% CI: -1.9, -0.8). For the well-educated women, injections and condoms became the first and second choices (29.5% and 21.5%), respectively, while female sterilization was the third option (17.9%) for contraceptive methods. Women's fear of their partners also affected the choice of contraceptive methods. The women who feared their partners were 7.0 percentage points more likely to choose female sterilization than condoms. CONCLUSION: Improvement in women's status (more education and less fear of their partners) changed their contraceptive behaviors by increasing the probability of choosing condoms and decreasing the probability of choosing female sterilization in Nepal. PMID- 29195635 TI - Impact of men's perception on family planning demand and uptake in Nigeria. AB - OBJECTIVE: Evidence from the last three Demographic and Health Surveys (DHS) in Nigeria shows slow progress in family planning (FP) uptake, despite programmatic interventions. While socioeconomic and religious barriers continue to exist, psychosocial factors such as negative contraceptive perceptions by male partners may influence both spousal FP demand and use. Therefore, this research investigates the influence of male partners' contraceptive perceptions on spousal FP demand and use. METHODS: We analysed the couple dataset from the 2013 Nigeria DHS. RESULTS: One in five men held the perception that contraceptive use is women's business whereas two in five men reported that women who use family planning may become promiscuous, especially older men, those with no formal education, Muslims and residents in rural areas and northern region. Results from regression models, controlling for relevant sociodemographic characteristics, show that men's perception that contraception is women's business did not significantly influence FP demand. However, their fear that women who use family planning may become promiscuous was associated with lower odds of FP demand (AOR: 0.86; 95% CI: 0.76-0.97) and increased the odds of traditional methods use (AOR: 1.34; 95% CI: 1.01-1.79). CONCLUSION: The findings direct the need to adopt targeted approach focusing on couples, and reorient policy and program efforts for FP counselling and behavioural changes in men. PMID- 29195636 TI - Attitudes of physicians providing family planning services in Egypt about recommending intrauterine device for family planning clients. AB - OBJECTIVES: To assess the attitudes of physicians providing family planning services at the public sector in Egypt about recommending intrauterine device (IUD) for family planning clients, and to identify the factors that could affect their attitudes. METHODS: A descriptive cross sectional study, in which all the physicians providing family planning services in Assiut Governorate were invited to complete self-administered questionnaires. The study participants were recruited at the family planning sector monthly meetings of the 13 health directorates of Assiut Governorate, Upper Egypt. 250 physicians accepted to participate in the study. Bivariate and Multivariate regression analyses were performed to identify the most important predictors of recommending IUD to family planning clients when appropriate. RESULTS: Less than 50% of physicians would recommend IUD for clients with proper eligibility criteria; women younger than 20 years old (49.2%), women with history of ectopic pregnancy (34%), history of pelvic inflammatory diseases (40%) or sexually transmitted diseases (18.4%) and nulliparous women (22.8%). Receiving family planning formal training within the year preceding data collection and working in urban areas were the significant predictors of recommending IUD insertion for appropriate clients. CONCLUSION: Physicians providing family planning services in Upper Egypt have negative attitudes about recommending IUD for family planning clients. Continuous education and in-service training about the updated medical eligibility criteria, especially for physicians working in rural areas may reduce the unfounded medical restrictions for IUD use. PMID- 29195637 TI - Professional confidence among Swedish final year midwifery students - A cross sectional study. AB - OBJECTIVE: Previous international studies have shown that midwifery students do not feel confident in many areas where they are supposed to practice independently. The knowledge about Swedish midwifery students' confidence is fairly under investigated. The purpose of the present study was to explore final years' midwifery students' professional confidence in basic midwifery skills according to ICM competencies and associated factors. METHODS: A cross-sectional survey where all midwifery programs in Sweden were invited to participate. Data was collected by a questionnaire that measured midwifery students self-reported assessment of confidence against four selected domains of ICM competencies; antenatal, intrapartum, postpartum and new-born care. RESULT: The main findings of this study showed that Swedish midwifery students were confident in managing normal pregnancy, labour and birth. Midwifery students at a school with a medical faculty were more confident in handling obstetric emergency situations. Some background variables were also associated with confidence. CONCLUSION: This study highlighted some midwifery skills that needs further training and reflection. More training and developing confidence in complicated and emergency situations are needed. There seem to be a need of midwifery education reforms if we believe that high levels of confidence at the time of graduation is equal to competent and skilled midwives in the future. PMID- 29195638 TI - Cause-specific mortality among women of reproductive age: Results from a population-based study in an Iranian community. AB - PURPOSE OF STUDY: This study was conducted to evaluate the levels, patterns, and causes of mortality among women of reproductive age in Northwestern Iran. METHODS: Deaths were determined for females resident in West Azerbaijan Province of Iran and who died between March 2013 to February 2014 using reproductive age mortality survey (RAMOS). Causes of death were ascertained by verbal autopsy (VA) and classified based on the International Classification of Diseases, tenth revision (ICD-10). Overall and cause-specific mortality rates (MRs) per 100,000 women with 95% confidence intervals were calculated. RESULTS: A total of 510 deaths were detected, and VA interviews were conducted with the relatives of the deceased Cases; overall MR was 56.59 per 100,000 women (95% CI: 56.49-56.69). The highest MR was observed in suicide cases (MR=10.21per 100,000women, 95% CI: 10.15 10.27), accounting for 18% of all deaths. The most common method of suicide was self-inflicted burns (45.6%), followed by deaths due to breast cancer (MR=4.22per 100,000women, 95% CI: 4.18-4.26), which accounted for the most cancer-related mortality. All-cause mortality was associated with age, area of residence, marital status, level of education, and ethnic (religious) status relationship (P<0.001). CONCLUSION: Suicide, especially self-immolation, was the main cause of death among women of reproductive age, and both suicides and breast cancer are major public health problems for this group of women. PMID- 29195639 TI - Married women's negotiation for safer sexual intercourse in Kenya: Does experience of female genital mutilation matter? AB - OBJECTIVE: Married women's ability to negotiate for safer sex is important for HIV prevention in sub-Saharan Africa, including Kenya. Yet, its relationship to female genital mutilation is rarely explored, although female genital mutilation has been described as a social norm and marker of womanhood that can control women's sexuality. Drawing on the social normative influence theory, this study addressed this void in the literature. METHODS: We analysed data from the 2014 Kenya Demographic and Health Survey using logistic regression. Our sample included 8,602 married women. Two indicators of safer sex, namely the ability to refuse sex and the ability to ask for condom use, were explored. RESULTS: We found that women who had undergone genital mutilation were significantly less likely to report that they can refuse sex (OR=0.87; p<.05) and that they can ask for condom use during sexual intercourse (OR=0.62; p<.001) than their counterparts who had not undergone genital mutilation, while controlling for theoretically relevant variables. CONCLUSION: Our findings indicate that the experience of female genital mutilation may influence married women's ability to negotiate for safer sex through gendered socialization and expectations. Based on these findings, several policy implications are suggested. For instance, culturally sensitive programmes are needed that target both married women who have undergone genital mutilation and their husbands to understand the importance of safer sexual practices within marriage. PMID- 29195640 TI - "We should be experts, but we're not": Sexual counselling at the antenatal care clinic. AB - OBJECTIVE: Several studies show that nurses don't meet patients' needs in addressing issues around sexuality and sexual health. However, little attention has been paid to midwives' views on sexual counselling. This study explores midwives' views and experiences on sexual counselling during antenatal care. STUDY DESIGN: Semi-structured interviews were conducted with nine midwives at seven different antenatal care clinics in southern Sweden. The interviews were analysed with qualitative content analysis, and script theory was used as a theoretical perspective. RESULTS: The result showed that the midwives considered sexuality important but hard to address. Lack of time, knowledge, and encouragement from the managerial level and/or lack of counselling tools were given as reasons for not bringing it up. In addition, midwives' insecurity turned out to be even greater with patients that deviated from the heterosexual norm or had another cultural background. CONCLUSION: There are cultural and interpersonal scripts in the workplace in which sexuality is not expected to be addressed. As long as these are in place, only education will not help to change issues in addressing patients' sexuality. Organizational and managerial support along with education and opportunities for reflection and dialogue regarding sexual issues might help midwives to approach sexuality and change the cultural and interpersonal scripts.

AB - This special issue consists of selected papers arising from the interdisciplinary conference "The Making of Measurement" held at the University of Cambridge on 23 24 July 2015. In this introduction, we seek ways to further productive interactions among historical, philosophical, and sociological approaches to the study of measurement without attempting to lay out a prescriptive program for a field of "measurement studies." We ask where science studies has led us, and answer: from the function to the making of measurement. We discuss whether there is anything privileged or exemplary about physical measurement, and alight upon models and metrology, two particular focuses of enquiry that emerge from our selection of papers. Those papers with a historical dimension complement an already well-developed body of historiography applied to measurement and metrology. PMID- 29195644 TI - Magnitude, moment, and measurement: The seismic mechanism controversy and its resolution. AB - This paper examines the history of two related problems concerning earthquakes, and the way in which a theoretical advance was involved in their resolution. The first problem is the development of a physical, as opposed to empirical, scale for measuring the size of earthquakes. The second problem is that of understanding what happens at the source of an earthquake. There was a controversy about what the proper model for the seismic source mechanism is, which was finally resolved through advances in the theory of elastic dislocations. These two problems are linked, because the development of a physically-based magnitude scale requires an understanding of what goes on at the seismic source. I will show how the theoretical advances allowed seismologists to re-frame the questions they were trying to answer, so that the data they gathered could be brought to bear on the problem of seismic sources in new ways. PMID- 29195645 TI - Acidity: Modes of characterization and quantification. AB - This paper provides an account of early historical developments in the characterization and quantification of acidity, which may be considered preliminary steps leading to the measurement of acidity. In this "pre-history" of acidity measurement, emphasis is laid on the relative independence of the rich empirical knowledge about acids from theories of acidity. Many attempts were made to compare and assess the strengths of various acids, based on concrete laboratory operations. However, at least until the arrival of the pH measure, the quantification attempts failed to produce anything qualifying as a measurement scale of a recognizable type. It is doubtful whether even pH qualifies as a true measure of acidity, when the full meaning of acidity is taken into account. PMID- 29195646 TI - The evaluation of measurement uncertainties and its epistemological ramifications. AB - The way metrologists conceive of measurement has undergone a major shift in the last two decades. This shift can in great part be traced to a change in the statistical methods used to deal with the expression of measurement results, and, more particularly, with the calculation of measurement uncertainties. Indeed, as we show, the incapacity of the frequentist approach to the calculus of uncertainty to deal with systematic errors has prompted the replacement of the customary frequentist methods by fully Bayesian procedures. The epistemological ramifications of the Bayesian approach merge with a deep empiricist mood tantamount to an "epistemic turn": measurement results are analysed in terms of degrees of belief, and central concepts such as error and accuracy are called into question. We challenge the perspective entailed by this epistemic turn: we insist on the centrality of the concepts of error and accuracy by underlining the intentional character of measurement that is intimately linked to the process of correction of experimental data. We further circumvent the difficulties posed by the classical analysis of measurement by stressing the social rather than the epistemic dimension of measurement activities. PMID- 29195647 TI - Calibration: Modelling the measurement process. AB - Calibration procedures establish a reliable relation between the final states ('indications') of a measurement process and features of the objects being measured ('outcomes'). This article analyzes the inferential structure of calibration procedures. I show that calibration is a modelling activity, namely the activity of constructing, deriving predictions from, and testing theoretical and statistical models of a measurement process. Measurement outcomes are parameter value ranges that maximize the predictive accuracy and mutual coherence of such models, among other desiderata. This model-based view of calibration clarifies the source of objectivity of measurement outcomes, the nature of measurement accuracy, and the close relationship between measurement and prediction. Contrary to commonly held views, I argue that measurement standards are not necessary for calibration, although they are useful in maintaining coherence across large networks of measurement procedures. PMID- 29195648 TI - A structural interpretation of measurement and some related epistemological issues. AB - Measurement is widely applied because its results are assumed to be more reliable than opinions and guesses, but this reliability is sometimes justified in a stereotyped way. After a critical analysis of such stereotypes, a structural characterization of measurement is proposed, as partly empirical and partly theoretical process, by showing that it is in fact the structure of the process that guarantees the reliability of its results. On this basis the role and the structure of background knowledge in measurement and the justification of the conditions of object-relatedness ("objectivity") and subject-independence ("intersubjectivity") of measurement are specifically discussed. PMID- 29195649 TI - The appeal to robustness in measurement practice. AB - This paper distinguishes between two arguments based on measurement robustness and defends the epistemic value of robustness for the assessment of measurement reliability. I argue that the appeal to measurement robustness in the assessment of measurement is based on a different inferential pattern and is not exposed to the same objections as the no-coincidence argument which is commonly associated with the use of robustness to corroborate individual results. This investigation sheds light on the precise meaning of reliability that emerges from measurement assessment practice. In addition, by arguing that the measurement assessment robustness argument has similar characteristics across the physical, social and behavioural sciences, I defend the idea that there is continuity in the notion of measurement reliability across sciences. PMID- 29195650 TI - Clinical outcome measurement: Models, theory, psychometrics and practice. AB - In the last decade much has been made of the role that models play in the epistemology of measurement. Specifically, philosophers have been interested in the role of models in producing measurement outcomes. This discussion has proceeded largely within the context of the physical sciences, with notable exceptions considering measurement in economics. However, models also play a central role in the methods used to develop instruments that purport to quantify psychological phenomena. These methods fall under the umbrella term 'psychometrics'. In this paper, we focus on Clinical Outcome Assessments (COAs) and discuss two measurement theories and their associated models: Classical Test Theory (CTT) and Rasch Measurement Theory. We argue that models have an important role to play in coordinating theoretical terms with empirical content, but to do so they must serve: 1) as a representation of the measurement interaction; and 2) in conjunction with a theory of the attribute in which we are interested. We conclude that Rasch Measurement Theory is a more promising approach than CTT in these regards despite the latter's popularity with health outcomes researchers. PMID- 29195651 TI - No actual measurement ... was required: Maxwell and Cavendish's null method for the inverse square law of electrostatics. AB - In 1877 James Clerk Maxwell and his student Donald MacAlister refined Henry Cavendish's 1773 null experiment demonstrating the absence of electricity inside a charged conductor. This null result was a mathematical prediction of the inverse square law of electrostatics, and both Cavendish and Maxwell took the experiment as verifying the law. However, Maxwell had already expressed absolute conviction in the law, based on results of Michael Faraday's. So, what was the value to him of repeating Cavendish's experiment? After assessing whether the law was as secure as he claimed, this paper explores its central importance to the electrical programme that Maxwell was pursuing. It traces the historical and conceptual re-orderings through which Maxwell established the law by constructing a tradition of null tests and asserting the superior accuracy of the method. Maxwell drew on his developing 'doctrine of method' to identify Cavendish's experiment as a member of a wider class of null methods. By doing so, he appealed to the null practices of telegraph engineers, diverted attention from the flawed logic of the method, and sought to localise issues around the mapping of numbers onto instrumental indications, on the grounds that 'no actual measurement ... was required'.

AB - At the 26th General Conference on Weights and Measures (CGPM) in November 2018, it is planned to adopt a new definition of the International System of Units, SI, based on the fixed numerical values of seven defining constants, broadly the fundamental constants of physics. This will be the culmination of more than two hundred years of metrology, instantiating for the first time the original ideas of the creators of the metric system. The key is the replacement of the present definition of the unit of mass, the kilogram artefact of platinum-iridium, by one based on a fixed numerical value of the Planck constant. This article outlines how this has come about, how it will work, why we need a system of measurement that is uniform, accessible world-wide and stable in the long term, and the international structures that now exist to achieve it. PMID- 29195653 TI - What's nu? A re-examination of Maxwell's 'ratio-of-units' argument, from the mechanical theory of the electromagnetic field to 'On the elementary relations between electrical measurements'. AB - This re-examination of the earliest version of Maxwell's most important argument for the electromagnetic theory of light-the equality between the speed of wave propagation in the electromagnetic ether and the ratio of electrostatic to electromagnetic measures of electrical quantity-establishes unforeseen connections between Maxwell's theoretical electrical metrology and his mechanical theory of the electromagnetic field. Electrical metrology was not neutral with respect to field-theoretic versus action-at-a-distance conceptions of electro magnetic interaction. Mutual accommodation between these conceptions was reached by Maxwell on the British Association for the Advancement of Science (BAAS) Committee on Electrical Standards by exploiting the measurement of the medium parameters-electric inductive capacity and magnetic permeability-on an arbitrary scale. While he always worked within this constraint in developing the 'ratio-of units' argument mathematically, I maintain that Maxwell came to conceive of the ratio 'as a velocity' by treating the medium parameters as physical quantities that could be measured absolutely, which was only possible via the correspondences between electrical and mechanical quantities established in the mechanical theory. I thereby correct two closely-related misconceptions of the ratio-of-units argument-the counterintuitive but widespread notion that the ratio is naturally a speed, and the supposition that Maxwell either inferred or proved this from its dimensional formula. PMID- 29195654 TI - Hubris to humility: Tonal volume and the fundamentality of psychophysical quantities. AB - Psychophysics measures the attributes of perceptual experience. The question of whether some of these attributes should be interpreted as more fundamental, or "real," than others has been answered differently throughout its history. The operationism of Stevens and Boring answers "no," reacting to the perceived vacuity of earlier debates about fundamentality. The subsequent rise of multidimensional scaling (MDS) implicitly answers "yes" in its insistence that psychophysical data be represented in spaces of low dimensionality. I argue the return of fundamentality follows from a trend toward increasing epistemic humility. Operationism exhibited a kind of hubris in the constitutive role it assigned to the experimenter's presuppositions that is abandoned by the algorithmic methods of MDS. This broad epistemic trend is illustrated by following the trajectory of research on a particular candidate attribute: tonal volume.

PMID- 29195659 TI - Validation of cardiac magnetic resonance tissue tracking in the rapid assessment of RV function: a comparative study to echocardiography. AB - AIM: To investigate the accuracy of cardiac magnetic resonance (CMR) tissue tracking (CMR-TT) and speckle tracking echocardiography (STE) against CMR determined right ventricular (RV) ejection fraction (RVEF) and to identify an optimal cut-off value for STE and CMR-TT to determine RVEF <45% and compare this to other conventional methods for estimating RVEF in dilated cardiomyopathy (DCM) patients. MATERIALS AND METHODS: Twenty-nine DCM patients were recruited prospectively. CMR and echocardiography were performed within 48 hours and four chamber views were used for strain analysis. Contoured CMR short axis images provided RVEF. Intraclass correlation coefficient (ICC), bias, levels of agreement, and receiver operating characteristic (ROC) curve analyses were performed. RESULTS: CMR-TT RV free-wall longitudinal strain (FLS) and STE RV global longitudinal strain (GLS) showed the best correlation with RVEF (r=-0.68, r=-0.82, p<0.001 respectively). There was moderate correlation between echocardiography RV GLS and CMR RV FLS (r=0.64, p<0.001). CMR-TT FLS showed excellent intra-observer and interobserver reliability (ICC=0.980; ICC=0.968 respectively). STE GLS correlated better with RVEF than with peak systolic annular velocity (S'; r=0.45), tricuspid annular plane systolic excursion (TAPSE; r=0.56), and fractional area change (FAC; r=0.78). CMR-TT RV FLS had better correlation with RVEF than CMR TAPSE (r=0.69 versus 0.40). ROC analysis demonstrated the optimal cut-off value for CMR-TT RV FLS and STE GLS in detection of RVEF <45% was >=-24.4% (area under the curve=0.87, 100% sensitivity, 66.7% specificity) and >=-20.9% (area under the curve=0.88, 100% sensitivity, 60% specificity) respectively. CONCLUSION: CMR-TT FLS and STE GLS showed potential to provide rapid assessment of RV function and had superior correlation with RVEF compared to conventional parameters. PMID- 29195660 TI - Detection of clinically occult primary tumours in patients with cervical metastases of unknown primary tumours: comparison of three-dimensional THRIVE MRI, two-dimensional spin-echo MRI, and contrast-enhanced CT. AB - AIM: To evaluate and compare the utility of contrast-enhanced three-dimensional (3D) T1-weighted high-resolution isotropic volume examination (THRIVE), spin-echo (SE) T1-weighted magnetic resonance imaging (MRI), and computed tomography (CT) for detecting clinically occult primary tumours in patients with cervical lymph node metastases. MATERIALS AND METHODS: Seventy-three consecutive patients with tumours that went undetected during endoscopic or physical examinations underwent preoperative contrast-enhanced CT and MRI (SE and 3D THRIVE) after gadolinium injection. Guided biopsy results served as reference standards. The diagnostic performances of the imaging techniques were compared with McNemar's tests. RESULTS: Primary tumours were identified in 59 (80.8%) of the 73 patients after surgery. Of these, 36 were found in the palatine tonsil, 11 in the base of the tongue, seven in the nasopharynx, and five in the pyriform sinus. The sensitivity (72.9%) and accuracy (71.2%) of 3D THRIVE for detecting primary tumours were higher than were those of SE T1-weighted MRI (49.2% and 53.4%, p<=0.002) or CT (36.4% and 46.4%, p<=0.001). The specificities of these techniques did not differ. The diagnostic performance of 3D THRIVE (area under the curve [AUC]=0.681) for detecting tumours did not differ from that of SE T1-weighted MRI or CT (AUC=0.671 and 0.608, p>0.05). CONCLUSION: 3D THRIVE was more sensitive at detecting primary tumours than was SE T1-weighted MRI or CT in patients with cervical metastases of unknown primary tumours. This sequence may improve biopsy and therapeutic planning in these patients. PMID- 29195661 TI - A study on the onset of turbulent conditions with supercritical fluid chromatography mobile-phases. AB - Following a recent publication [1], the topic of turbulent flow in SFC has generated both interest and questions. Liquid-like density, coupled with significantly low viscosity of CO2-based mobile-phases may result in high Reynolds number (Re) - higher than what represents laminar flow conditions, reaching the so-called turbulent regions. Although such turbulent flows can form only in the connecting tubings, thus not directly affecting the chromatographic process, it is important to know under many situations, whether the flow inside the tubing is laminar or turbulent. In this report a comprehensive guideline to identify the possibilities of turbulent flow conditions is provided through a series of charts. Flow properties depend on state conditions (composition, pressure and temperature) and also on the tubing material and geometry. Here guidelines to detect the onset of turbulent conditions is provided for cylindrical stainless-steel tubings of different internal diameters (i.d.) under a wide range of SFC mobile-phase conditions. PMID- 29195662 TI - Differentiation of modern and ancient varieties of common wheat by quantitative capillary electrophoretic profile of phenolic acids. AB - Phenolic compounds have received great attention among the health promoting phytochemicals in common wheat (Triticum aestivum L.), mainly because of their strong antioxidant properties. In the present study a simple Capillary Zone Electrophoresis (CZE) method with UV detection was optimized and validated for the quantitation of six of the most important phenolic acids in whole grain i.e., sinapic, ferulic, syringic, p-coumaric, vanillic and p-hydroxybenzoic acid. The separation was achieved in a running buffer composed of sodium phosphate solution (50 mM) in water/methanol 80:20 (v/v) at pH 6.0 and using a fused-silica capillary at the temperature of 30 degrees C under application of 27 kV. By means of diode array detector, and made possible by the favorable characteristic UV spectra, the quantitation of the solutes was carried out at 200, 220 and 300 nm, in the complex matrices represented by the soluble and bound fractions of wheat flours. The validation parameters of the method i.e., linearity, sensitivity, precision, accuracy and robustness were in line with those obtained by consolidated separation techniques applied for the same purposes (e.g., HPLC UV), with a significant advantage in term of analysis time (less than 12 min). Ten varieties of soft wheat (five modern Italian and five old Italian genotypes) were analysed and the data were subjected to Principal Components Analysis (PCA). Interestingly, significant differences of the quantitative phenolic acids profile were observed between the modern and the ancient genotypes, with the latter showing higher amount of the main represented phenolic acids. PMID- 29195663 TI - Forensic age-at-death estimation from the sternum in a black South African population. AB - Age-at-death estimation is a crucial component of any forensic anthropological analysis. Despite a variety of research in this field, uncertainties still exist when estimating adult age. The sternum is an under-considered element in terms of adult age estimation. Previous research on an Indian population suggested that this may be a usable region of the skeleton, although results were ambivalent. This study observed the fusion phases of 461 sterna from a black South African population in an attempt to match true age of an individual with the different phases of synostosis of the manubrio-sternal and the sterno-xiphoidal junctions. The results demonstrated that the majority of sterna remain unfused throughout adult life, with complete fusion observed both in young (25 year-old) and old individuals. Significant differences were identified amongst male and female sterna, with males presenting no transitional fusion of the segments, while female sterna demonstrated fusion to a lesser extent. Overall, logistic regression results demonstrated low accuracies (62.5%) for age estimation even when the two sexes were considered separately (male=63.9%; female=61.8%). The synostosis of both junctions is hence considered highly variable and deemed unreliable for adult age-at-death estimation in the black South African population. PMID- 29195664 TI - [Actinomycosis revealed by ulceration of the palate and gingiva]. AB - BACKGROUND: Actinomycosis is a chronic and extensive granulomatous, bacterial infection. Revelation by oral ulceration is rare. PATIENTS AND METHODS: A 76-year old patient with diabetes was treated with dabrafenib for stage IV melanoma. A follow-up visit revealed two ulcerated, infiltrated and hyperalgesic lesions of the palate and gingiva. There were no associated signs. The laboratory findings were normal. The possibility of squamous cell carcinoma occurring with BRAF inhibitors was discussed, despite the rarity of such cases in the literature. Histological examination showed an actinomycotic grain. A scan of the facial mass showed no osteitis. Antimicrobial therapy was initiated with amoxicillin for four months, with a favorable outcome. DISCUSSION: Actinomycetes are Gram-positive filamentous saprophytic bacteria of the oral cavity and the gastrointestinal tract. They can become pathogenic under the influence of several factors. Cervicofacial involvement in the form of a peri-mandibular inflammatory nodule with secondary fistulation on the skin or in the mouth is the classic presentation. To our knowledge, no cases of opportunistic infection under BRAF inhibitors have been described. Only two cases of tuberculosis have been reported with sorafenib. The initial presentation led to suspicion of squamous cell carcinoma. In our patient, poor oral hygiene and diabetes were the two key factors considered. Moreover, this is the first case reported under dabrafenib, which does not appear to be a favoring factor. We would stress the importance of mucosal examination in patients treated with BRAF inhibitors. PMID- 29195666 TI - Mind the gap - Why is implementing research into practice so challenging? PMID- 29195665 TI - Wearing of examination gloves and hygiene practice among dermatologists: A national survey. AB - INTRODUCTION: Touch is essential for dermatologists. Differences in practice, such as whether or not to wear examination gloves, may be seen among dermatologists. To investigate this approach and its associated factors, we conducted a national survey to study hygiene measures and the wearing of gloves among dermatologists, e.g. wearing a coat, hand washing between patient visits, hand shaking and past history of infectious disease transmitted by patients. The context and circumstances in which gloves were worn was studied. RESULTS: Four hundred and seventy-four dermatologists responded to the survey (median age: 52 years). Most dermatologists reported wearing examination gloves as follows: always (21%, n=99), occasionally (76%, n=359), never (3%, n=13). Most physicians reported wearing a coat (91%, n=419) and routinely washing their hands after examination (53%, n=241). A minority of physicians reported shaking hands (36%, n=163). A significant number of dermatologists reporting that they wore examination gloves were younger and female, and these practitioners also washed their hands more frequently. The most common reason cited by dermatologists wearing gloves "occasionally" was patient hygiene (71%, n=256) rather than infectious skin disease (52%, n=186). This practice was ascribable more to concerns by dermatologists about protecting themselves (78%, n=270) rather than protecting patients (51%, n=169). Finally, it was felt that wearing gloves impaired neither the quality of clinical examination (52%, n=173) nor relations with patients (49%, n=160). CONCLUSION: Although wearing gloves is not recommended for examining unbroken skin, most of the respondents reported wearing examination gloves during their consultations. Wearing of gloves was associated with more frequent hygiene measures (hand washing, no handshaking) and was based on concern for self-protection. PMID- 29195667 TI - Alcohol, smoking and the GI tract. PMID- 29195668 TI - Key role of local acetaldehyde in upper GI tract carcinogenesis. AB - Ethanol is neither genotoxic nor mutagenic. Its first metabolite acetaldehyde, however, is a powerful local carcinogen. Point mutation in ALDH2 gene proves the causal relationship between acetaldehyde and upper digestive tract cancer in humans. Salivary acetaldehyde concentration and exposure time are the two major and quantifiable factors regulating the degree of local acetaldehyde exposure in the ideal target organ, oropharynx. Instant microbial acetaldehyde formation from alcohol represents >70% of total ethanol associated acetaldehyde exposure in the mouth. In the oropharynx and achlorhydric stomach acetaldehyde is not metabolized to safe products, instead in the presence of alcohol it accumulates in saliva and gastric juice in mutagenic concentrations. A common denominator in alcohol, tobacco and food associated upper digestive tract carcinogenesis is acetaldehyde. Epidemiological studies on upper GI tract cancer are biased, since they miss information on acetaldehyde exposure derived from alcohol and acetaldehyde present in 'non-alcoholic' beverages and food. PMID- 29195669 TI - Tobacco smoking, alcohol consumption and gastro-oesophageal reflux disease. AB - Gastro-oesophageal reflux disease (GORD) develops when reflux of gastric content causes troublesome symptoms or complications. The main symptoms are heartburn and acid regurgitation and complications include oesophagitis, strictures, Barrett's oesophagus and oesophageal adenocarcinoma. In addition to hereditary influence, GORD is associated with lifestyle factors, mainly obesity. Tobacco smoking is regarded as an aetiological factor of GORD, while alcohol consumption is considered a triggering factor of reflux episodes and not a causal factor. Yet, both tobacco smoking and alcohol consumption can reduce the lower oesophageal sphincter pressure, facilitating reflux. In addition, tobacco smoking reduces the production of saliva rich in bicarbonate, which is important for buffering and clearance of acid in the oesophagus. Alcohol also has a direct noxious effect on the oesophageal mucosa, which predisposes to acidic injury. Tobacco smoking cessation reduces the risk of GORD symptoms and avoidance of alcohol is encouraged in individuals where alcohol consumption triggers reflux. PMID- 29195670 TI - Alcohol, smoking and risk of oesophago-gastric cancer. AB - Oesophago-gastric cancers (oesophageal and gastric cancers) are common, highly fatal cancers. Oesophageal squamous cell carcinoma (OSCC) and oesophageal adenocarcinoma (OAC) are the two main histological subtypes of oesophageal cancer. Globally, OSCC remains the most common histological subtype of oesophageal cancer, with the highest burden occurring along two geographic belts, one from north central China through the central Asian republics to northern Iran, and one from eastern to southern Africa. In Western countries, the incidence of OAC has increased dramatically over the past 40 years. OAC is now the most common subtype of oesophageal cancer in the United States, United Kingdom, and Australia. Approximately 90% of gastric cancers are adenocarcinoma, with the majority of cases diagnosed in Eastern Asia, Eastern Europe, and some Latin American countries. Smoking is an established risk factor for both oesophageal (OSCC and OAC) and gastric cancers. Alcohol consumption, however, is strongly associated with increased risk of OSCC and probably increases the risk of gastric cancer, but is not associated with OAC. Here, we review the current epidemiological evidence on associations between alcohol consumption, smoking and the risk of developing oesophago-gastric cancer, and emphasize the importance of focusing efforts on controlling the worldwide burden of oesophago-gastric cancer by reducing alcohol and tobacco use. PMID- 29195671 TI - Alcohol, smoking and benign hepato-biliary disease. AB - Gallstone disease and pancreatitis are the most frequent benign hepato-biliary causes of hospital admissions. Gallstone disease is prevalent, but symptomatic disease develops only in about one out of five carriers. Alcohol intake seems to protect gallstone formation in cohort studies possibly through effects on bile cholesterol metabolism, the enterohepatic circulation, and gallbladder function. The impact of smoking on gallstone formation seems minor. Both alcohol intake and smoking do not alter the clinical course of gallstone disease carriers. Cholecystectomy is the preferred treatment for symptomatic gallstone disease. Studies about the impact of alcohol and smoking on the post-cholecystectomy state are few and future studies should be performed. Pancreatitis is associated with both excessive alcohol intake and smoking in observational studies. Interpretation of associations with pancreatitis is hampered by an incomplete understanding of underlying mechanisms and by the co-existence of excessive alcohol intake and smoking. Smoking cessation and alcohol abstinence is recommended in the treatment of pancreatitis, but higher-level evidence is needed. PMID- 29195673 TI - Alcohol, smoking and the liver disease patient. AB - Alcohol is an established risk factor for cirrhosis. Current recommendations for a "safe" limit for alcohol consumption are usually set to around 30 g of alcohol per day for men and 20 g per day for women, but evidence is mounting that these cut-offs might be set too high. Also, inter-individual differences in the hepatic sensitivity for alcohol likely play into the risk of development of cirrhosis. In patients with concomitant liver diseases, a synergistic effect on fibrosis progression and high consumption of alcohol is evident. The role of low to moderate consumption is less clear. Alcohol can also lead to a specific inflammatory state in the liver, alcoholic hepatitis (AH). Treatment of severe AH consists of corticosteroids, which are at best moderately effective, and new treatments are needed. Liver transplantation is an option in severe alcoholic liver disease, although selection of patients that are at a very low risk of post transplantation alcohol consumption is paramount. There is some evidence to suggest an increased risk for fibrosis progression and development of hepatocellular carcinoma specifically for smoking. PMID- 29195672 TI - Tobacco and alcohol as risk factors for pancreatic cancer. AB - Pancreatic cancer is projected to become the leading cause of cancer deaths by 2050. The risk for pancreatic cancer may be reduced by up to 27% by modifying lifestyle risk factors, most notably tobacco smoking. Based on analysis of more than 2 million unselected individuals from general population, this article quantified the risk of pancreatic cancer in relation to lifelong tobacco smoking and alcohol consumption status, both alone and in combination. It also provided a state-of-the-art review of animal studies on the effect of tobacco smoke and alcohol on genetically engineered mouse models of pancreatic precursor lesions, as well as the role of immune microenvironment in pancreatic carcinogenesis activated by tobacco and alcohol. PMID- 29195674 TI - The role of smoking and alcohol behaviour in management of functional gastrointestinal disorders. AB - Functional gastrointestinal disorders (FGIDs) are common disorders in the population. Lifestyle habits have been suspected to influence the presence and degree of symptoms, and many studies have examined the role of food components and physical activity on the disease development. The role of smoking and alcohol intake on FGID has been less thoroughly examined. This systematic literature review, of a large amount of studies from different countries around the world with different design and application of FGID criteria, shows that smoking seems to be associated with a significant 50% increased risk of FD for current compared with never smokers. The associations between smoking and other FGIDs are weak, if present at all. A moderate alcohol intake is not associated with FGIDs. On the other hand, a high alcohol intake may lead to development and aggravation of FGID symptoms, especially functional dyspepsia. PMID- 29195675 TI - The role of smoking and alcohol behaviour in the management of inflammatory bowel disease. AB - In the era of increasing use of immunosuppressive and biologic therapy for inflammatory bowel disease, environmental influences remain important independent risk factors to modify the course of the disease, affect the need for surgery and recurrence rates post-surgical resection. The effect of smoking on inflammatory bowel disease has been established over the decades, however the exact mechanism of how smoking affects remains as area of research. Alcohol is also among the socio-environmental factors which has been recognised to cause a flare of symptoms in inflammatory bowel disease patients. Nonetheless, the exact relation to date is not fully understood, and various paradoxical results from different studies are still a point of controversy. PMID- 29195676 TI - Alcohol, smoking and the risk of premalignant and malignant colorectal neoplasms. AB - Colorectal cancer (CRC) is the third most common cancer worldwide and has a complex aetiology consisting of environmental and genetic factors. In this review, we evaluate the roles of alcohol and tobacco smoking in colorectal neoplasia. Alcohol intake and tobacco smoking are associated with modest, but significantly, increased risks of CRC, adenomatous and serrated polyps. There is consistent evidence of dose-response relationships for both alcohol and smoking, and risk of these neoplasms. Alcohol and smoking appear to be more strongly associated with colorectal polyp than CRC development, suggesting roles in the initiation of neoplastic growths. These lifestyle factors also seem more strongly related to adenomas and sessile serrated lesions than hyperplastic polyps, but further confirmation is required. The gastroenterology community has an important, yet currently underexploited, role to play addressing the modifiable factors associated with CRC and polyps. These behaviours include, but are not limited to, alcohol and smoking. PMID- 29195677 TI - Do smoking and alcohol behaviours influence GI cancer survival? AB - Little is known about the role of alcohol and smoking in GI cancer survival compared to GI cancer development. We systematically reviewed the evidence for a role of smoking and alcohol in prognosis among GI cancer patients and inform whether smoking or alcohol cessation interventions or guidelines for GI cancer patients are likely to improve prognosis. A total of 84 relevant studies were identified. Continued smokers, particularly heavy smokers, had worse prognosis than never smokers in most GI cancers. However, more evidence is needed to establish the likely impact of smoking cessation interventions amongst GI cancer patients. Heavy alcohol drinkers had worse prognosis in oesophageal squamous cell carcinoma and hepatocellular carcinoma patients. Light alcohol consumption was not associated with worse prognosis from any GI cancer, though further studies are needed. UK guidelines for the general population recommending under 14 units (~7 drinks) per week may be sufficient for GI cancer patients, until further evidence is available. PMID- 29195678 TI - The interaction between smoking, alcohol and the gut microbiome. AB - The gastrointestinal microbiome is a complex echosystem that establishes a symbiotic, mutually beneficial relation with the host, being rather stable in health, but affected by age, drugs, diet, alcohol, and smoking. Alcohol and smoking contribute to changes in the stomach and affect H pylori-related disorders including the risk of gastric cancer. In the small intestine and in the colon alcohol causes depletion of bacteria with anti-inflammatory activity, eventually resulting in intestinal damage with "leaky gut". These changes contribute to hepatic damage in both alcoholic and non-alcoholic liver disease and have been associated with other disorders. Lactobacillus GG and A. muciniphila exert a protective effect in this setting. Smoking leads to modifications of the gut microbiome linked with a protective effect toward ulcerative colitis and deleterious for Crohn's disease. The exact cause-effect relation between alcohol and smoking and changes of the gastrointestinal microbiome needs further exploration with high throughput methodologies, and controlled studies are necessary to define the role of microbiome modulation on the immune response and systemic activation of pro-inflammatory pathways. PMID- 29195679 TI - Impact of alcohol & smoking on the surgical management of gastrointestinal patients. AB - Alcohol and smoking are repeatedly described as modifiable risk factors in clinical studies across all surgical specialities. These lifestyle choices impart a sub-optimal physiology via multiple processes and play an important role in the surgical management of the gastrointestinal patient. Cessation is imperative to optimise the patient's fitness for surgery with surgery itself being a prime opportunity for sustained cessation. A consistent, planned and integrated management involving surgical, anaesthetic, medical, and primary care facets will aid in successful cessation and perioperative care. This review highlights the pathological processes which contribute to perioperative complications and details the current practices to detect, predict and appropriately manage the perioperative gastrointestinal patient who smokes and consumes alcohol. PMID- 29195680 TI - Communication of alcohol and smoking lifestyle advice to the gastroenterological patient. AB - Effective communication between healthcare staff and patients is central to development of the patient-professional relationship. Many barriers influence this communication, often resulting in patients' lack of understanding and retention of information, particularly affecting advice regarding lifestyle habits, such as alcohol consumption and smoking. Alcohol and smoking misuse are potentially modifiable risk factors known to adversely affect a variety of gastroenterological conditions and improvements in communication with patients regarding this is an important management component. This review discusses the clinical impact of these factors and how healthcare professionals can improve communication. We discuss how enhancing verbal communication skills through medical training leads to greater outcomes in patient satisfaction and adherence to treatment and advice. In addition, with the rapid digitalisation of society, platforms such as social media and smartphone applications may be considered as adjuncts to traditional forms of communication. PMID- 29195681 TI - Compression sonography for non-invasive measurement of lower leg compartment pressure in an animal model. AB - INTRODUCTION: Compression ultrasound is a non-invasive technique allowing for qualitative visualization and quantitative measurements of mechanical tissue properties. In acute compartment syndrome (ACS), cadaver studies have proven that the intra-compartmental pressure (ICP) measured by compression sonography correlates with the ICP measured invasively. This study aimed to evaluate compression sonography for compartment pressure measurements in an animal model. MATERIAL AND METHODS: The pressure in the anterior tibial compartment of 6 domestic pig legs was increased from baseline to 40mmHg in 5mmHg steps. Using compression sonography, the compartment diameter was measured without external pressure and during manual application of five levels of external pressure. The elasticity ratio (ER) was computed as the ratio of the compartment diameter with and without external pressure. At 40mmHg of external pressure the ERs at different ICP levels were compared using repeated ANOVA measurements. Post-hoc comparisons evaluated the lowest detectable ICP fulfilling the definition of ACS (ICP>=30mmHg) by starting from each pressure below 30mmHg (baseline, 20mmHg and 25mmHg, respectively). Receiver operator characteristic analyses defined ER limits with appropriate sensitivity and specificity to detect ACS. RESULTS: The ER increased from 79.0% at baseline ICP to 89.3% at 40mmHg ICP. The ER at baseline and at 20mmHg ICP significantly differed from the ER at 30mmHg ICP (p=0.007 and 0.002, respectively); the ER at 25mmHg ICP significantly differed from the ER at 40mmHg ICP (p=0.001). An ER less than 87.1% had a sensitivity of 94.4% and a specificity of 88.9% to proper diagnosis of ACS. CONCLUSION: Compression sonography might offer a non-invasive technique to guide treatment in cases of uncertain acute compartment syndrome. Further studies are needed to collect elasticity ratio data in humans and to clinically validate compression sonography for compartment pressure measurements. PMID- 29195682 TI - Development of a heat vulnerability index for New York State. AB - OBJECTIVES: The frequency and intensity of extreme heat events are increasing in New York State (NYS) and have been linked with increased heat-related morbidity and mortality. But these effects are not uniform across the state and can vary across large regions due to regional sociodemographic and environmental factors which impact an individual's response or adaptive capacity to heat and in turn contribute to vulnerability among certain populations. We developed a heat vulnerability index (HVI) to identify heat-vulnerable populations and regions in NYS. STUDY DESIGN: Census tract level environmental and sociodemographic heat vulnerability variables were used to develop the HVI to identify heat-vulnerable populations and areas. METHODS: Variables were identified from a comprehensive literature review and climate-health research in NYS. We obtained data from 2010 US Census Bureau and 2011 National Land Cover Database. We used principal component analysis to reduce correlated variables to fewer uncorrelated components, and then calculated the cumulative HVI for each census tract by summing up the scores across the components. The HVI was then mapped across NYS (excluding New York City) to display spatial vulnerability. The prevalence rates of heat stress were compared across HVI score categories. RESULTS: Thirteen variables were reduced to four meaningful components representing 1) social/language vulnerability; 2) socioeconomic vulnerability; 3) environmental/urban vulnerability; and 4) elderly/ social isolation. Vulnerability to heat varied spatially in NYS with the HVI showing that metropolitan areas were most vulnerable, with language barriers and socioeconomic disadvantage contributing to the most vulnerability. Reliability of the HVI was supported by preliminary results where higher rates of heat stress were collocated in the regions with the highest HVI. CONCLUSIONS: The NYS HVI showed spatial variability in heat vulnerability across the state. Mapping the HVI allows quick identification of regions in NYS that could benefit from targeted interventions. The HVI will be used as a planning tool to help allocate appropriate adaptation measures like cooling centers and issue heat alerts to mitigate effects of heat in vulnerable areas.

PMID- 29195684 TI - Mice lacking interleukin-18 gene display behavioral changes in animal models of psychiatric disorders: Possible involvement of immunological mechanisms. AB - Preclinical and clinical evidence suggests pro-inflammatory cytokines might play an important role in the neurobiology of schizophrenia and stress-related psychiatric disorders. Interleukin-18 (IL-18) is a member of the IL-1 family of cytokines and it is widely expressed in brain regions involved in emotional regulation. Since IL-18 involvement in the neurobiology of mental illnesses, including schizophrenia, remains unknown, this work aimed at investigating the behavior of IL-18 null mice (KO) in different preclinical models: 1. the prepulse inhibition test (PPI), which provides an operational measure of sensorimotor gating and schizophrenic-like phenotypes; 2. amphetamine-induced hyperlocomotion, a model predictive of antipsychotic activity; 3. resident-intruder test, a model predictive of aggressive behavior. Furthermore, the animals were submitted to models used to assess depressive- and anxiety-like behavior. IL-18KO mice showed impaired baseline PPI response, which was attenuated by d-amphetamine at a dose that did not modify PPI response in wild-type (WT) mice, suggesting a hypodopaminergic prefrontal cortex function in those mice. d-Amphetamine, however, induced hyperlocomotion in IL-18KO mice compared to their WT counterparts, suggesting hyperdopaminergic activity in the midbrain. Moreover, IL 18KO mice presented increased basal levels of IL-1beta levels in the hippocampus and TNF-alpha in the prefrontal cortex, suggesting an overcompensation of IL-18 absence by increased levels of other proinflammatory cytokines. Although no alteration was observed in the forced swimming or in the elevated plus maze tests in naive IL-18KO mice, these mice presented anxiogenic-like behavior after exposure to repeated forced swimming stress. In conclusion, deletion of the IL-18 gene resembled features similar to symptoms observed in schizophrenia (positive and cognitive symptoms, aggressive behavior), in addition to increased susceptibility to stress. The IL-18KO model, therefore, could provide new insights into how changes in brain immunological homeostasis induce behavioral changes related to psychiatric disorders, such as schizophrenia.

PMID- 29195686 TI - Role of Bile Acids in Metabolic Control. AB - Bile acids are endocrine molecules that in addition to facilitating the absorption of fat-soluble nutrients regulate numerous metabolic processes, including glucose, lipid, and energy homeostasis. The signaling actions of bile acids are mediated through specific bile-acid-activated nuclear and membrane bound receptors. These receptors are not only expressed by tissues within the enterohepatic circulation such as the liver and the intestine, but also in other organs where bile acids mediate their systemic actions. In this review, we discuss bile acid signaling and the interplay with the gut microbiota in the pathophysiology of obesity, type 2 diabetes, and non-alcoholic fatty liver disease, and the role of surgical and pharmacological interventions on bile acid profiles and metabolism.

AB - BACKGROUND: Etiologies contributing to failure to wean from mechanical ventilation (MV) are multiple, resulting in morbid and costly outcomes. Diaphragm pacing (DP) is used in spinal cord injury to replace MV. Temporary DP could be utilized in acute respiratory failure to reduce MV. METHODS: A prospective FDA feasibility trial evaluated temporary DP electrodes implanted in each hemi diaphragm during a subject's primary procedure. Objectives included: ability to provide ventilation, stability analysis with diaphragm electromyography, and adverse event monitoring. RESULTS: Twelve patients underwent successful implantation via median sternotomy, laparoscopy or laparotomy. Electrode stimulation exceeded ideal tidal volumes by an average of 37% (0%-95%) confirming ability to prevent atrophy. Daily electromyography confirmed stability of placement and was useful in evaluating hypoventilation. There were no complications and all 48 study electrodes remained intact until complete removal. CONCLUSION: This trial demonstrates ease of placement, removal, functionality and safety of temporary DP electrodes which therapeutically decreases diaphragm atrophy.

METHODS: A retrospective analysis of a colonoscopy database was reviewed. All patients that underwent colonoscopy secondary to focal incidental uptake on PET/CT were evaluated. PET/CT findings were correlated with endoscopic and histopathological results. RESULTS: 84 patients underwent colonoscopy secondary to incidental focal colorectal uptake on PET/CT. A total of 63 patients had an endoscopic and histological confirmation of the area of abnormality, for a positive predictive value of 75%. Newly diagnosed colorectal carcinoma was discovered in 13 patients (15.4%) and forty-four patients (52.3%) were discovered to have a premalignant lesion. CONCLUSION: Incidental focal colorectal uptake of 18 F-fluorodeoxyglucose is associated with a substantial risk of underlying neoplastic colorectal lesions. Early identification of these lesions may alter patient management and treatment plans. PMID- 29195692 TI - Evaluation of Medical Students' Perception of an Ophthalmology Career.

PMID- 29195695 TI - The diagnosis and management of morbidly adherent placenta. AB - The incidence of morbidly adherent placenta (MAP) has risen 13-fold since the early 1900s and is directly correlated with the rising rate of cesarean delivery. It is important for clinicians to screen all pregnancies for MAP at the time of routine second-trimester ultrasonography. In addition, patients with risk factors (e.g., multiple prior cesarean deliveries) should undergo targeted screening for MAP. Optimal maternal and fetal outcomes for these high-risk pregnancies result from accurate prenatal diagnosis and comprehensive multidisciplinary preparation and delivery between 34 and 36 weeks of gestation. There continue to be large knowledge gaps with respect to the optimal management of this condition especially around diagnosis, obstetric care, timing of delivery, and surgical management. Accordingly, most recommendations are based on expert opinion rather than on high-quality evidence. Prospective clinical trials are needed to address knowledge gaps and to continue to improve outcomes.

AB - Clinical evidence has indicated the effectiveness of computer-based systems for preventing and reducing diagnostic errors. Our study aimed to evaluate the effectiveness of UpToDate, a computer-based clinical knowledge management system, for reducing diagnostic errors. We retrospectively identified 100 patients who visited an outpatient department in a community-based hospital from July 2014 to June 2015. Fifty patients (exposure group) were seen by UpToDate-equipped physicians and another 50 (control group) were seen by UpToDate-unequipped physicians. We extracted data on patient sex, age, primary diagnosis, and case difficulty that could potentially affect diagnostic outcomes. We compared the two groups regarding diagnostic error rate and performed logistic regression analysis to analyze the concurrent effects of various factors affecting diagnostic error. The diagnostic error rate was 2% in the exposure group, while the error rate was 24% in the control group. Multivariate logistic regression analysis showed that error rate reduction was significantly associated with exposure to UpToDate with an odds ratio of 15.21 (95% CI 1.86-124.36). Our results demonstrated the effectiveness of UpToDate for the prevention and reduction of diagnostic error.

AB - PURPOSE: Despite the great potential Health Information Systems (HIS) have in improving the quality of healthcare delivery services, very few studies have been carried out on the adoption of such systems in developing countries. This article is concerned with investigating the adequacy of UTAUT1 in determining factors that influence the adoption of HIS by clinicians in developing countries, based on the case of Cameroon. METHODS: A paper-based questionnaire was distributed to clinicians in 4 out of 7 major public hospitals in Cameroon. A modified UTAUT was tested using structural equation modeling (SEM) method to identify the determinants of clinicians' intention to use HIS. Self-efficacy and cost effectiveness were determinants used to extend the original UTAUT. RESULTS: 228 out of 286 questionnaires were validated for this study. The original UTAUT performed poorly, explaining 12% of the variance in clinicians' intention to use HIS. Age was the only significant moderating factor, improving the model to 46%. Self-efficacy and cost effectiveness has no direct significant effect on HIS adoption in the context of this study. CONCLUSIONS: The original UTAUT is not adequate in identifying factors that influence the adoption of HIS by clinicians in developing countries. Simplifying the model by using age as the only moderating factor significantly increases the model's ability to predict HIS adoption in this context. Thus, the younger clinicians are more likely and ready to adopt HIS than the older ones. Context-specific should also be used to increase the explanatory power of UTAUT in any given context.

AB - INTRODUCTION: Electronic medical record (EMR) systems can yield many benefit; however, facilities need to meet certain requirements before they are able to successfully implement an EMR. We evaluated the feasibility and utility of conducting EMR readiness assessments (ERAs) to assess readiness of public facilities in Kenya for deployment of an EMR. METHOD: I-TECH supported the Ministry of Health to deploy KenyaEMR, an HIV/AIDS care and treatment EMR developed using the OpenMRS platform, at over 300 healthcare facilities in Kenya. The ERA tool was designed to assess site readiness for KenyaEMR deployment. The assessments measured health facility internal environment in terms of available resources, security, technical infrastructure, and leadership buy-in and support from MOH and stakeholders for EMR implementation. RESULTS: From September 2012 to September 2014, a total of 381facilities received at least one ERA. Of these, 343facilities were rated as highly or moderately prepared to adopt an EMR system and proceeded to EMR deployment. 61% of these sites were set up to implement KenyaEMR at point of care, while 39% were set up to implement KenyaEMR for retrospective data entry. Across 38facilities not implemented with an EMR, common reasons that prevented the implementation were lack of reliable power, security issues such as lack of grills on the windows and un-lockable doors, and existence of another EMR system at the site. CONCLUSIONS: ERAs conducted in a single day site visit were feasible and were instrumental in determining facilities' EMR implementation decision. Performing ERAs stimulated engagement of facility-level personnel to cultivate a fertile environment for EMR adoption and ownership. The assessments further assisted in resource mobilization, remediation of barriers to deployment, and increased buy-in from Ministry of Health leadership to support EMR implementation work. PMID- 29195703 TI - Supervised learning methods for pathological arterial pulse wave differentiation: A SVM and neural networks approach. AB - OBJECTIVE: The main goal of this study was to develop an automatic method based on supervised learning methods, able to distinguish healthy from pathologic arterial pulse wave (APW), and those two from noisy waveforms (non-relevant segments of the signal), from the data acquired during a clinical examination with a novel optical system. MATERIALS AND METHODS: The APW dataset analysed was composed by signals acquired in a clinical environment from a total of 213 subjects, including healthy volunteers and non-healthy patients. The signals were parameterised by means of 39pulse features: morphologic, time domain statistics, cross-correlation features, wavelet features. Multiclass Support Vector Machine Recursive Feature Elimination (SVM RFE) method was used to select the most relevant features. A comparative study was performed in order to evaluate the performance of the two classifiers: Support Vector Machine (SVM) and Artificial Neural Network (ANN). RESULTS AND DISCUSSION: SVM achieved a statistically significant better performance for this problem with an average accuracy of 0.9917+/-0.0024 and a F-Measure of 0.9925+/-0.0019, in comparison with ANN, which reached the values of 0.9847+/-0.0032 and 0.9852+/-0.0031 for Accuracy and F Measure, respectively. A significant difference was observed between the performances obtained with SVM classifier using a different number of features from the original set available. CONCLUSION: The comparison between SVM and NN allowed reassert the higher performance of SVM. The results obtained in this study showed the potential of the proposed method to differentiate those three important signal outcomes (healthy, pathologic and noise) and to reduce bias associated with clinical diagnosis of cardiovascular disease using APW. PMID- 29195704 TI - Stakeholder influence in public sector information systems strategy implementation-The case of public hospitals in South Africa. AB - Recent literature on organisational strategy has called for greater emphasis on individuals (stakeholders) and what they do in the process of strategizing. Public sector organisations have to engage with an array of heterogeneous stakeholders in fulfilling their mandate. The public health sector in particular needs to engage with a diversity of stakeholders at local, regional and national levels when strategising. The purpose of this study is to investigate the influence of stakeholder relations on the implementation of Information Systems (IS) strategy in public hospitals in South Africa. An interpretive approach using two provinces was employed. The Activity Analysis and Development (ActAD) framework, an enhanced form of activity theory, was used as the theoretical framework. Data was collected using semi-structured interviews, meetings, documents analysis, physical artefacts and observation. The collected data was analysed using thematic analysis. Findings reveal that IS strategy implementation in public hospitals involves a large and complex network of stakeholder groups at different levels, and over different time periods. These stakeholder groups act in accordance with formal and informal roles, rules and modalities. Various contextual conditions together with the actions of, and interactions between stakeholder groups give rise to the situationality of stakeholder relations dynamics and strategy implementation. The multiple actions and interactions over time lead to the realisation of some aspects of the IS strategy in public hospitals. Given the complexity and dynamism of the context there are also certain unplanned implementations as well. These relationships are captured in a Stakeholder Relations Influence (SRI) framework. The SRI framework can be assistive in the assessment and mapping of stakeholders and stakeholder relations, and the assessment of the implications of these relations for effective IS strategy implementation in public hospitals. The framework can also provide the basis for the development of appropriate corrective measures in the implementation of strategies and policies in public institutions such as public hospitals. PMID- 29195705 TI - Schedule-based metrics for the evaluation of clinic performance and potential recovery of cancelled appointments. AB - BACKGROUND: Assessment of outpatient clinic performance is important to optimize patient access. Metrics based on schedule data may assist with assessment of operational efficiency and recovering cancelled appointments. OBJECTIVES: To define schedule-based characteristics of clinic operations and to evaluate potential for recovery of cancelled appointments. METHODS: Sixty-seven weekly cardiology clinics from a single provider over 18 months at an academic medical center were analyzed. Parameters included clinic slots eligible to have patients scheduled (available), slots occupied by appointments (scheduled), and slots for which patients attended the associated visit (appeared). Rates of usage (scheduled/available), appearance (appeared/scheduled), and utilization (appeared/available=usage rate*appearance rate) were calculated. Surplus slots were defined as the difference between available slots and slots occupied by patients that appeared. Cancellation lag-time was defined as the interval between a cancellation and the appointment time. If a patient did not notify the clinic regarding a non-appearance, cancellation lag-time was set to zero. To quantify the impact of a change in clinic operations on efficiency, these metrics were used to evaluate a different cardiologist's clinic before and after its physical location moved. RESULTS: For approximately 900 patient visits, usage and appearance rates were~80%, yielding a utilization rate of ~2/3. On average, there were nearly 8 surplus slots per clinic. Approximately 30% of cancellation lag times had positive values and nearly half of positive cancellation lag-times were >3h, indicating potential for recovery of those appointments. The intervention analysis showed that usage rate decreased and surplus slots per clinic increased significantly after a change in clinic location. CONCLUSIONS: Schedule-based analysis provides a framework to assess changes to clinic operations, identify mechanisms underlying inefficiency, and suggest solutions for improving clinic performance (i.e. more schedulers in response to low usage rates). Cancellation lag-time analysis suggests recovering a portion of same-day cancellations is plausible. PMID- 29195706 TI - Longitudinal study of user experiences of a CPOE system in a pediatric hospital. AB - OBJECTIVE: To explore the views of nurses and doctors during the early stages of implementation of a computerized provider order entry (CPOE) system in a pediatric hospital and to examine changes in perceptions and reported behaviors as use of the CPOE system became routine. METHODS: Semi-structured interviews were undertaken at four time points following CPOE implementation: during week one, week three, week six and then six months following implementation. In total, 122 users were interviewed. Interviews were audio-recorded and transcribed verbatim. Emergent themes were mapped to the Extended Technology Acceptance Model (e-TAM). RESULTS: Initial perceptions were driven by unfamiliarity with the system. As users became more proficient and efficient in using the CPOE system, additional safety benefits become apparent. However, accompanying increased reports of benefits were reports of usability problems and new types of errors arising from CPOE use. Reports of workarounds appeared for the first time at 6 month interviews. These workarounds were adopted to allow routine work to continue and to attenuate some of the perceived negative consequences of CPOE, including delayed medications and reduced patient interaction. CONCLUSION: This study is one of the first to examine changes in perceptions of CPOE at multiple points, demonstrating the trajectory of changes in views over time. It provides new information about the time point at which workarounds begin to be embedded in practice and are potentially most receptive to identification and remediation. It suggests an adaptive implementation and support program would be beneficial, as reported difficulties and concerns change during the first six months of use. PMID- 29195707 TI - iCBLS: An interactive case-based learning system for medical education. AB - Medical students should be able to actively apply clinical reasoning skills to further their interpretative, diagnostic, and treatment skills in a non-obtrusive and scalable way. Case-Based Learning (CBL) approach has been receiving attention in medical education as it is a student-centered teaching methodology that exposes students to real-world scenarios that need to be solved using their reasoning skills and existing theoretical knowledge. In this paper, we propose an interactive CBL System, called iCBLS, which supports the development of collaborative clinical reasoning skills for medical students in an online environment. The iCBLS consists of three modules: (i) system administration (SA), (ii) clinical case creation (CCC) with an innovative semi-automatic approach, and (iii) case formulation (CF) through intervention of medical students' and teachers' knowledge. Two evaluations under the umbrella of the context/input/process/product (CIPP) model have been performed with a Glycemia study. The first focused on the system satisfaction, evaluated by 54 students. The latter aimed to evaluate the system effectiveness, simulated by 155 students. The results show a high success rate of 70% for students' interaction, 76.4% for group learning, 72.8% for solo learning, and 74.6% for improved clinical skills. PMID- 29195708 TI - A new computationally efficient algorithm for record linkage with field dependency and missing data imputation. AB - Record linkage algorithms aim to identify pairs of records that correspond to the same individual from two or more datasets. In general, fields that are common to both datasets are compared to determine which record-pairs to link. The classic model for probabilistic linkage was proposed by Fellegi and Sunter and assumes that individual fields common to both datasets are completely observed, and that the field agreement indicators are conditionally independent within the subsets of record pairs corresponding to the same and differing individuals. Herein, we propose a novel record linkage algorithm that is independent of these two baseline assumptions. We demonstrate improved performance of the algorithm in the presence of missing data and correlation patterns between the agreement indicators. The algorithm is computationally efficient and can be used to link large databases consisting of millions of record pairs. An R-package, corlink, has been developed to implement the new algorithm and can be downloaded from the CRAN repository. PMID- 29195709 TI - Tracking word semantic change in biomedical literature. AB - Up to this point, research on written scholarly communication has focused primarily on syntactic, rather than semantic, analyses. Consequently, we have yet to understand semantic change as it applies to disciplinary discourse. The objective of this study is to illustrate word semantic change in biomedical literature. To that end, we identify a set of representative words in biomedical literature based on word frequency and word-topic probability distributions. A word2vec language model is then applied to the identified words in order to measure word- and topic-level semantic changes. We find that for the selected words in PubMed, overall, meanings are becoming more stable in the 2000s than they were in the 1980s and 1990s. At the topic level, the global distance of most topics (19 out of 20 tested) is declining, suggesting that the words used to discuss these topics are stabilizing semantically. Similarly, the local distance of most topics (19 out of 20) is also declining, showing that the meanings of words from these topics are becoming more consistent with those of their semantic neighbors. At the word level, this paper identifies two different trends in word semantics, as measured by the aforementioned distance metrics: on the one hand, words can form clusters with their semantic neighbors, and these words, as a cluster, coevolve semantically; on the other hand, words can drift apart from their semantic neighbors while nonetheless stabilizing in the global context. In relating our work to language laws on semantic change, we find no overwhelming evidence to support either the law of parallel change or the law of conformity. PMID- 29195710 TI - Health IT and inappropriate utilization of outpatient imaging: A cross-sectional study of U.S. hospitals. AB - OBJECTIVE: To determine whether the use of information technology (IT), measured by Meaningful Use capability, is associated with lower rates of inappropriate utilization of imaging services in hospital outpatient settings. RESEARCH DESIGN: A retrospective cross-sectional analysis of 3332 nonfederal U.S. hospitals using data from: Hospital Compare (2011 outpatient imaging efficiency measures), HIMSS Analytics (2009 health IT), and Health Indicator Warehouse (market characteristics). Hospitals were categorized for their health IT infrastructure including EHR Stage-1 capability, and three advanced imaging functionalities/systems including integrated picture archiving and communication system, Web-based image distribution, and clinical decision support (CDS) with physician pathways. Three imaging efficiency measures suggesting inappropriate utilization during 2011 included: percentage of "combined" (with and without contrast) computed tomography (CT) studies out of all CT studies for abdomen and chest respectively, and percentage of magnetic resonance imaging (MRI) studies of lumbar spine without antecedent conservative therapy within 60days. For each measure, three separate regression models (GLM with gamma-log link function, and denominator of imaging measure as exposure) were estimated adjusting for hospital characteristics, market characteristics, and state fixed effects. Additionally, Heckman's Inverse Mills Ratio and propensity for Stage-1 EHR capability were used to account for selection bias. PRINCIPAL FINDINGS: We find support for association of each of the four health IT capabilities with inappropriate utilization rates of one or more imaging modality. Stage-1 EHR capability is associated with lower inappropriate utilization rates for chest CT (incidence rate ratio IRR=0.72, p-value <0.01) and lumbar MRI (IRR=0.87, p-value <0.05). Integrated PACS is associated with lower inappropriate utilization rate of abdomen CT (IRR=0.84, p-value <0.05). Imaging distribution over Web capability is associated with lower inappropriate utilization rates for chest CT (IRR=0.66, p value <0.05) and lumbar MRI (IRR=0.86, p-value <0.05). CDS with physician pathways is associated with lower inappropriate utilization rates for abdomen CT (IRR=0.87, p-value <0.01) and lumbar MRI (IRR=0.90, p-value <0.05). All other cases showed no association. CONCLUSIONS: The study offers mixed results. Taken together, the results suggest that the use of Stage-1 Meaningful Use capable EHR systems along with advanced imaging related functionalities could have a beneficial impact on reducing some of the inappropriate utilization of outpatient imaging. PMID- 29195711 TI - Better specification of triggers to reduce the number of drug interaction alerts in primary care. AB - OBJECTIVE: Drug interaction alerts (drug-drug and drug-disease interaction alerts) for chronic medications substantially contribute to alert fatigue in primary care. The aim of this study was to determine which events require (re)assessment of a drug interaction and whether using these events as triggers in clinical decision support systems (CDSSs) would affect the alert rate. METHODS: Two random 5% data samples from the CDSSs of 123 community pharmacies were used: dataset 1 and 2. The top 10 of most frequent drug interaction alerts not involving laboratory values were selected. To reach consensus on events that should trigger alerts (e.g. first time dispensing, dose modification) for these drug interactions, a two-step consensus process was used. An expert panel of community pharmacists participated in an online survey and a subsequent consensus meeting. A CDSS with alerts based on the consensus was simulated in both datasets. RESULTS: Dataset 1 and 2 together contained 1,672,169 prescriptions which led to 591,073 alerts. Consensus on events requiring alerts was reached for the ten selected drug interactions. The simulation showed a reduction of the alert rate of 93.0% for the ten selected drug interactions (comparable for dataset 1 and 2), corresponding with a 28.3% decrease of the overall drug interaction alert rate. CONCLUSION: By consensus-based better specification of the events that trigger drug interaction alerts in primary care, the alert rate for these drug interactions was reduced by over 90%. This promising approach deserves further investigation to assess its consequences and applicability in daily practice. PMID- 29195712 TI - Arthrodesis Versus Carpometacarpal Preservation in Key-Grip Procedures in Tetraplegic Patients: A Comparative Study of 40 Cases. AB - PURPOSE: Constructing a lateral key pinch (KP) is a universal aim of any functional upper limb surgery program for tetraplegia. Three stages are required: (1) activating the pinch mechanism by flexor pollicis longus tenodesis to the radius or by tendon transfer to the flexor pollicis longus, (2) simplifying the polyarticular chain, and (3) positioning the thumb column. We compared 2 techniques for accomplishing the latter stage, 1 utilizing arthrodesis of the carpometacarpal joint (CMC) and 1 that did not require arthrodesis of the CMC. MATERIALS AND METHODS: We reviewed 40 cases of KP reconstruction at a mean follow up of 7.4 years: 17 who had undergone CMC arthrodesis and 23 without CMC arthrodesis. In this group, an abductor pollicis longus tenodesis was necessary to properly position the thumb column in 17 patients. RESULTS: Active KP cases with CMC arthrodesis were significantly stronger than those without an arthrodesis. For passive KP cases, the difference between those cases with CMC arthrodesis and those without was not significant. Regarding opening, for active KP cases with CMC preservation alone, the mean distance between the thumb pulp and the index finger was 4.0 cm at rest and 5.8 cm when passively grasping large objects; for active KP cases without arthrodesis, these values were 3.4 and 6.8 cm, respectively, with the wrist in flexion. For passive KP cases, these values were 2.2 and 3.5 cm with CMC arthrodesis compared with 2.4 and 6.9 cm without arthrodesis. Overall, 23.5% of patients with CMC arthrodesis could not maintain contact between the thumb and the index finger compared with 30.4% without arthrodesis. CONCLUSIONS: Active KP is stronger with than without CMC arthrodesis; however, the KP reconstruction does not open as far when grasping large objects. For passive KP, CMC arthrodesis significantly limits passive opening, with no gain in strength. Neither technique is superior in terms of KP stability. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV. PMID- 29195713 TI - Generic antiretroviral drug use in HIV-infected patients: A cohort study from the French health insurance database. AB - OBJECTIVE: This study aimed to estimate the rate of generic users among HIV infected patients treated by antiretroviral (ARV) drugs potentially substitutable and to determine factors associated with switch from brand to generic ARV in real life settings in a French region. METHODS: Cohort of HIV-infected patients aged of >=18 years, exposed to at least one of the generic of lamivudine (3TC 150mg/300mg), zidovudine/lamivudine (AZT-200mg/3TC-150mg), nevirapine (NVP 200mg), efavirenz (EFV-600mg) and those exposed to brand 3TC, AZT/3TC, NVP, EFV, the fixed-dose combination abacavir/lamivudine (ABC/3TC) or the single-tablet regimen efavirenz/emtricitabine/tenofovir (EFV/FTC/TDF) as recorded in the French health insurance database between January 2012 and May 2015 were included. Factors associated with switch (for each generic versus its brand drug; and for situation requiring breaking the combination) were investigated through a logistic regression. RESULTS: Among the 1539 patients likely to switch from brand ARV drugs, only 165 (11%) were exposed to generics. For EFV users, switch from brand to generic was associated with age (aOR=1.04 [CI: 1.00-1.08]). For ABC/3TC users, switch was significantly more frequent in patients receiving a monthly average of more than two non-ARV drugs (3.08 [1.42-6.68]) and whose regimen contained a non-nucleoside reverse transcriptase inhibitor (NNRTI) as index medication (3rd agent) (5.68 [2.68-11.39]). By contrast, switch was less frequent in AZT/3TC users exposed to drugs used in digestive disorders (0.39 [0.18-0.88]) or analgesics (0.42 [0.20-0.90]). CONCLUSION: Treatment-experienced HIV patients whose disease has been stabilized (less comorbidities) are more likely to switch to generic antiretroviral drugs. PMID- 29195714 TI - [Gastric acid rebound after a proton pump inhibitor: Narrative review of literature]. AB - BACKGROUND: Since the introduction of the first proton pump inhibitor (PPI) 20 years ago, studies have examined the presence of a rebound effect when this treatment is discontinued. These studies are heterogeneous and contradictory: the last literature review on the rebound in gastric acidity dates from 2006 and did not allow to conclude on the subject. Our objective was to carry out an up-to date literature review on the existence and characteristics of this gastric acid rebound at the end of PPIs. METHODS: We conducted a review of the literature on the gastric acid rebound, without excluding the design of the studies. The Medline(r) databases (PubMed), ISI (Web Of Science) and Google Scholar were queried using the following equation: ("inhibitor proton pump" OR omeprazole OR esomeprazole OR lansoprazole OR pantoprazole OR rabeprazole) AND "rebound" AND "Acid hypersecretion". Only studies with a measure (whatever it was) before and after treatment were analyzed. RESULTS: Of the 131 publications identified, 10 were selected. The design of the studies was very heterogeneous. Five studies concluded a rebound effect. Studies with a treatment duration of less than 4 weeks did not demonstrate a rebound effect. The colonization with Helicobacter pylori masked the appearance of the rebound. CONCLUSION: Daily PPI exposure for more than 4 weeks is likely to trigger a rebound of acid hypersecretion about 15 days after discontinuation, and lasting from a few days to several weeks depending on the duration of the exposure. PMID- 29195715 TI - Utilization of a lateral flow colloidal gold immunoassay strip based on surface enhanced Raman spectroscopy for ultrasensitive detection of antibiotics in milk. AB - An ultrasensitive method for the detection of antibiotics in milk is developed based on inexpensive, simple, rapid and portable lateral flow immunoassay (LFI) strip, in combination with high sensitivity surface-enhanced Raman spectroscopy (SERS). In our strategy, an immunoprobe was prepared from colloidal gold (AuNPs) conjugated with both a monoclonal antibody against neomycin (NEO-mAb) and a Raman probe molecule 4-aminothiophenol (PATP). The competitive interaction with immunoprobe between free NEO and the coated antigen (NEO-OVA) resulted in the change of the amount of the immobilized immunoprobe on the paper substrate. The LFI procedure was completed within 15min. The Raman intensity of PATP on the test line of the LFI strip was measured for the quantitative determination of NEO. The IC50 and the limit of detection (LOD) of this assay are 0.04ng/mL and 0.216pg/mL of NEO, respectively. There is no cross-reactivity (CR) of the assay with other compounds, showing high specificity of the assay. The recoveries for milk samples with added NEO are in the range of 89.7%-105.6% with the relative standard deviations (RSD) of 2.4%-5.3% (n=3). The result reveals that this method possesses high specificity, sensitivity, reproducibility and stability, and can be used to detect a variety of antibiotic residues in milk samples. PMID- 29195716 TI - The impact of the recommendation of routine rotavirus vaccination in Germany: An interrupted time-series analysis. AB - BACKGROUND: Rotavirus is a highly contagious virus causing gastroenteritis, mostly in children under the age of 5. Since 2006, two vaccines are available in Germany. In 2013, these were included into the German national vaccination schedule. The aim of this intervention is to reduce the incidence and hospitalization among children under 5 years caused by rotavirus. The effectiveness of the intervention was analyzed in this study. METHODS: National surveillance data of laboratory confirmed rotavirus infections among children under the age of 5 were analyzed using interrupted time-series analysis. Weekly incidence from 2011 to 2017 and monthly hospital discharge rates from 2005 to 2015 were analyzed using a segmented generalized linear model with Poisson distribution. RESULTS: After adjusting for seasonal effects the incidence were approximately 22% (95% CI: 13.2-30.1) lower than expected following the intervention. The hospitalizations were approximately 27% (95% CI: 14.9-39.7) lower than expected following the intervention. The long-term effects of the intervention were nearly zero. The incidence changed in trend by -0.2% (95% CI: 0.1 to (-0.3)) and the hospitalizations by +0.2% (95% CI: 1.2-(-0.8)) following the intervention. CONCLUSION: After the inclusion of the vaccines into the national vaccination schedule significant immediate effects of this intervention were found. The weekly incidences and monthly hospitalization caused by the rotavirus were more than 20% lower than expected. The long-term effects of the intervention however were found to be nearly zero. This could be caused by a low vaccination rate in the German population. PMID- 29195717 TI - The efficacy of two different dosages of hepatitis B immunoglobulin combined with hepatitis B vaccine in preventing mother-to-child transmission of hepatitis B virus: A prospective cohort study. AB - BACKGROUND/AIMS: A birth dose of hepatitis B immunoglobulin (HBIG), in combination with hepatitis B vaccine (HepB), is recommended for infants born to hepatitis B surface antigen (HBsAg)-positive mothers. However, the optimal dosage of HBIG remains to be resolved. This prospective cohort study aimed to compare the efficacy of two dosages of HBIG combined with HepB to prevent mother-to-child transmission (MTCT) of HBV. METHODS: From 2009 to 2011, we prospectively enrolled mother-infant pairs with positive maternal HBsAg in China. Infants were assigned to receive one dose of 100 IU or 200 IU HBIG within 12 h of birth according to maternal numbering, followed by completion of the 3-dose 10 MUg HepB series. At 7 months, post-vaccination serologic testing (PVST) was performed in 545 and 632 infants in 100 IU and 200 IU HBIG groups, respectively, among whom, 451 and 529 were followed up to 12 months. RESULTS: Maternal and birth characteristics were comparable between infants in 100 IU and 200 IU HBIG groups. At 7 months, the rates of perinatal infection were 1.5% (8/545) and 1.9% (12/632) in 100 IU and 200 IU HBIG groups, respectively (p = .568). One non-responder infant in 200 IU HBIG group became newly infected at 12 months. The antibody to hepatitis B surface antigen (anti-HBs) positive rates were 98.5% (529/537) and 98.2% (609/620) in 100 IU and 200 IU HBIG groups at 7 months, respectively (p = .704), and the corresponding figures were 98.2% (431/439) and 97.1% (496/511) at 12 months (p = .266). The anti-HBs geometric mean concentrations were comparable between two groups at 7 months (707.95 mIU/mL vs. 602.56 mIU/mL, p = .062) and 12 months (245.47 mIU/mL vs. 229.09 mIU/mL, p = .407). CONCLUSIONS: One birth dose of 100 IU HBIG, combined with the HepB series, might be enough for preventing MTCT of HBV in infants born to HBsAg-positive mothers. PMID- 29195719 TI - What do health coaches do? Direct observation of health coach activities during medical and patient-health coach visits at 3 federally qualified health centers. AB - OBJECTIVE: To examine activities of health coaches during patient medical visits and when meeting one-on-one with patients at 3 urban federally qualified health centers. METHODS: Encounters were videotaped and transcribed. Data was analyzed using a matrix analysis approach that allowed a priori identification of expected categories of activity, based on the health coach training model and previously developed conceptual framework, which were modified based on activities observed. RESULTS: A total of 10 medical visits (patient, clinician and health coach), and 8 patient-coach visits were recorded. We identified 9 categories common to both medical and patient-coach visits and 2 categories unique to the medical visit. While observed activities were generally consistent with expected categories, some activities were observed infrequently or not at all. We also observed additional activity categories, including information gathering and personal conversation. The average amount of time spent on some categories of coaching activities differed substantially between medical visits and patient-coach visits. CONCLUSIONS: Health coaching activities observed differed in several respects to those expected, and differed between medical visits and coaching only visits. PRACTICE IMPLICATIONS: These results provide insights into health coaching behaviors that can be used to inform training and improve utilization of health coaches in practice. PMID- 29195718 TI - Patient, caregiver and physician perspectives on participating in a thoracic rapid tissue donation program. AB - OBJECTIVE: The collection of posthumous tissue from advanced stage lung cancer patients is beneficial to medical science. Recruiting living patients to a Rapid Tissue Donation Program (RTD) poses several psychosocial challenges and little is known about perceptions of joining this type of program. This study qualitatively examined perceptions of advanced stage lung cancer patients (n=14) participating in a lung cancer RTD program, their NoK (n=11), and physicians (n=6) at the Thoracic Oncology Clinic at H. Lee Moffitt Cancer Center & Research Institute, Tampa, Florida USA. METHODS: Semi-structured interviews were conducted with participants and interview transcripts were analyzed using the constant comparison method. RESULTS: Majority of patients joined to give back to research, discussed participation with family members, and desired for family to receive information about the use of the tissue after their death. All participating NoK were supportive of their family member's decision. Physicians described the program as running smoothly, but provided suggestions for process improvements. CONCLUSION: Participants joined with intention to give back to research community and families were supportive of loved one's participation in RTD. Physicians agreed with overall process. PRACTICE IMPLICATIONS: Key factors for a successful RTD program is tailoring to institutional and individual needs.

AB - OBJECTIVE: The aim of this study was to examine the role of autologous dermis-fat grafts in the reconstruction of orbital soft-tissue defects. PATIENTS: Thirty-six patients (3-84 years) were enrolled in this retrospective study from 2002 to 2014. The dermis-fat graft was primarily transplanted in seven cases, and secondarily in 29 patients. All the patients were evaluated for complications, adequate prosthetic cavity, possibility of artificial eye supply and movement, as well as cosmetic results. Follow-up periods ranged from 25 to 144 months. RESULTS: All the patients could be supplied with an artificial eye in the long term after dermis-fat transplantation. The clinical evaluation revealed 17 complications allocated to 11 patients. A major complication occurred in three patients (8.3%) so that a surgical correction was necessary. Thirty-three patients (91.7%) showed an aesthetically stable long-term outcome. CONCLUSION: Dermis-fat grafts for reconstruction of anophthalmic orbit represent a reliable method with a low complication rate and good cosmetic and functional results. The graft can be used as primary and secondary transplants. The stable long-term results and high aesthetic satisfaction lead us to recommend this method as a routine operation. PMID- 29195723 TI - A non-language-specific speech test to evaluate the speech of cleft patients from different language and cultural backgrounds - A pilot study. AB - Cleft speech tests are not universally available. We developed a tool to fill this gap, especially in the context of a cleft mission setting. We performed a pilot study to evaluate the test's ability to differentiate between the speech of cleft patients and healthy individuals from three different language backgrounds. We used 78 made-up, nonsensical syllables to evaluate hypernasality, nasal emissions, and consonant errors. Cleft (n = 41) and non-cleft (n = 39) individuals from three countries were included in this study. Two speech and language pathologists, blinded to the examination, rated the audio recording independently. Patients from Germany (n = 12; mean age 15.2), Iran (n = 14; mean age 7), and India (n = 15; mean age 14.7 years) were evaluated. We observed a significant difference in each category (p < 0.05) between patients and control subjects of the same language and cultural background. Hypernasality was affected the most. The test proved to possess the correct phonetic characteristics to reveal and provoke relevant cleft speech pathologies independent of cultural and language backgrounds. The test sounds posed no articulatory difficulties to non cleft individuals, with some exceptions regarding non-specific consonant errors. A comparison with other existing tests will further illuminate its value as a speech test. PMID- 29195724 TI - Sensing of Cytoskeletal Forces by Asymmetric Adherens Junctions. AB - Within tissues, key cellular adaptations occur via mechanotransduction responses at cell-cell junctions. Adherens junctions (AJs) typically form between cells as a result of the binding of cadherin receptors of the same type (homotypic), and are linked to the force-propagating and -generating actomyosin cytoskeleton. Recent studies have found that AJs maintain monolayer integrity in dynamic tissues and drive collective cell behavior by converting into asymmetric remodeling entities. Here, we overview the molecular processes that may explain how asymmetric cell-cell junctions sense differences in cytoskeletal geometry between cells. We discuss the link between cadherin-complex dynamics and the actomyosin cytoskeleton at asymmetric cell-cell junctions. We then outline the role of Bin/Amphiphysin/Rvs (BAR) proteins, cytoplasmic regulators of endocytosis and cytoskeletal dynamics that sense force-induced membrane curvature, at AJs undergoing asymmetric remodeling. Lastly, we highlight the physiological importance of junctional asymmetry for epithelial and vascular tissue and discuss its potential role in disease. PMID- 29195725 TI - Benefits of a bedtime routine in young children: Sleep, development, and beyond. AB - This paper presents a conceptual model and reviews the empirical evidence to support a nightly bedtime routine as a key factor in the promotion of not only healthy sleep, but also of broad development and wellbeing in early childhood. A bedtime routine embodies the characteristics of nurturing care and early child stimulation, which are deemed to be essential for positive outcomes, especially for at-risk children. Furthermore, common, adaptive components of a bedtime routine can contribute to an array of positive developmental outcomes beyond improved sleep, inclusive of language development, literacy, child emotional and behavioral regulation, parent-child attachment, and family functioning, among other outcomes. These bedtime routine components include activities in the broad domains of nutrition (e.g., feeding, healthy snack), hygiene (e.g., bathing, oral care), communication (e.g., reading, singing/lullabies) and physical contact (e.g., massage, cuddling/rocking). A bedtime routine can provide multiple benefits to child and family functioning at a time of day that many parents are present with their children. Although additional research on hypothesized routine related child outcomes and mechanisms of action are needed, promoting a bedtime routine may be a feasible and cost-effective method to promote positive early childhood development worldwide, particularly for socioeconomically disadvantaged and other at-risk young children. PMID- 29195726 TI - Cardiovascular effects of oral appliance therapy in obstructive sleep apnea: A systematic review and meta-analysis. AB - Obstructive sleep apnea (OSA) is associated with increased cardiovascular morbidity and mortality. This study systematically reviews the effects of oral appliance therapy (OAT) on a broad spectrum of cardiovascular outcomes. A literature search was performed up to December 31st 2016. Twenty-five relevant full-text articles were retrieved. Sixteen articles were considered methodologically sufficient, including 11 randomized controlled trials. Pooled data of the RCTs showed significant reductions in daytime systolic and diastolic blood pressure compared to baseline, but no significant reductions in heart rate, except for daytime heart rate when compared to inactive/placebo OAT. OAT and continuous positive airway pressure (CPAP) were equally effective in reducing blood pressure. Studies assessing the effect of OAT on heart rate variability, circulating cardiovascular biomarkers, and endothelial function and arterial stiffness, generally involved small numbers of patients, and were heterogeneous and inconclusive. Studies assessing the effect of OAT on cardiac function showed no effects on echocardiographic outcomes. One observational study showed that OAT was as effective as CPAP in reducing cardiovascular death. It could be speculated that OAT may lead to a reduction in long-term cardiovascular morbidity and mortality in OSA patients. However, further methodologically high quality, longitudinal studies are warranted to address this key question. PMID- 29195728 TI - Old journal, new media. PMID- 29195727 TI - Clinical and imaging findings of pattern dystrophy subtypes; Diagnostic errors and unnecessary treatment in clinical practice. AB - PURPOSE: To evaluate the clinical and multimodal imaging findings of various pattern dystrophy (PD) subtypes and report the initial misdiagnosis rate of PD patients resulting in unnecessary treatment in actual clinical practice. METHODS: Retrospective, observational study. Forty eyes of 24 patients with PD were included. The distribution of PD subtypes, optical coherence tomography (OCT) and fundus autofluorescence (FAF) findings, initial misdiagnoses, revised diagnoses, duration between misdiagnosis and revised diagnosis, and unnecessary treatments administered were evaluated over this time-period. RESULTS: Twenty-eight eyes (70%) showed adult-onset foveomacular vitelliform dystrophy, 6 eyes (15%) showed butterfly PD (BPD), 4 eyes (10%) showed reticular PD, and 2 eyes (5%) showed PD simulating fundus flavimaculatus and BPD mixed type PD. Most of the patients showed various types of hyperreflective material in the subretinal space on OCT, and hyperautofluorescence on FAF imaging. Eighteen eyes (45%) had a true PD diagnosis initially, whereas 22 (55%) of them were misdiagnosed as age-related macular degeneration, central serous chorioretinopathy, or non-specific RPE change. The mean duration between the initial and revised diagnosis was 18.7+/ 16.8 months. In addition, 5 eyes in the misdiagnosed group underwent intravitreal anti-vascular endothelial growth factor treatment during this period. CONCLUSION: Pattern dystrophies are a heterogeneous group of macular disorders which may mimic several macular diseases. By knowing the multimodal imaging findings, especially the distinctive FAF findings of the PDs, we may easily diagnose the disease and save our patients from unnecessary treatments. PMID- 29195729 TI - Orthostatic hypotension in Parkinson disease: Impact on health care utilization. AB - INTRODUCTION: Orthostatic hypotension (OH) represents a frequent yet overlooked source of disability in Parkinson disease (PD). In particular, its impact on health care utilization has been insufficiently examined. We sought to determine the differential health care utilization in PD patients with (PDOH+) and without OH (PDOH-). METHODS: We quantified the emergency room (ER) visits, hospitalizations, outpatient clinic evaluations, phone calls, and e-mails from PD patients on whom supine and orthostatic blood pressure (BP) measurements were obtained during routine clinical practice between June 2013 and July 2016. Comparative costs between PDOH+ and PDOH- were adjusted for age, disease duration, motor severity, levodopa equivalent daily dose, and Montreal Cognitive Assessment. RESULTS: From a total of 317 PD patients, 29.3% were classified as PDOH+ (n = 93) and 70.6% as PDOH- (n = 224) over 30.2 +/- 11.0 months, in which there were 247 hospitalizations, 170 ER visits, 2386 outpatient evaluations, and 4747 telephone calls/e-mails. After-adjusting for relevant covariates, PDOH+ was associated with more hospitalization days (+285%; p = 0.041), ER visits (+152%; p = 0.045), and telephone calls/e-mails than PDOH- (+142%; p = 0.009). The overall health care-related cost in PDOH+ was 2.5-fold higher than for PDOH- ($25,205 +/- $6546 vs. $9831 +/- $4167/person/year; p = 0.037). CONCLUSION: OH increases health care utilization in PD independently from age, disease duration, motor severity, dopaminergic treatment, and cognitive function. PMID- 29195730 TI - Tobacco smoking and electronic cigarette: two sides of the same coin? PMID- 29195731 TI - Pharmaceutical interventions in mental health: A review of the literature to support evidence-informed policymaking. AB - BACKGROUND: Pharmaceutical interventions may have an impact on different treatment aspects, such as therapy adherence, reducing the number of different medications in use and lowering treatment costs. OBJECTIVE: Identify pharmaceutical interventions in the mental health field and their possible application in Brazilian public mental health services, considering the evidence based model to establish implementation options. METHODS: A structured search of the literature was performed in the Pubmed (Medline), Cochrane, PsycINFO and Lilacs databases to identify the main pharmaceutical intervention studies conducted in the mental health area. The articles selected were evaluated according to the quality of the evidence. The current laws and public database were researched to collect information on services and procedures provided by the Brazilian units, known as CAPS, and the number the pharmacists allocated to them. The proposal to synthesize the results of pharmaceutical interventions in Brazil was based on SUPPORT methodology items to prepare evidence-based policies. RESULTS: A total of 1442 studies were identified, 18 of which were included. Several interventions are reported in the literature, educational interventions being frequently cited. However, there is a need for further studies with more methodological rigor. The number of pharmacists working in the CAPS is insufficient to cover all the services, since only 26.5% of CAPS employ pharmacists, who work an average of 29 (+/-11.1) hours a week. Three options were formulated to implement interventions in the Brazilian context that consider including pharmacists on the basic team of CAPS professionals and educational interventions through pharmacist training. CONCLUSIONS: The present study could support the establishment of health policies, based on a synthesis of the evidence, contextualization of the current situation, given the absence of local evidence, and a discussion of the options available to implement pharmaceutical interventions in the Brazilian health system. Organizational changes in CAPS are needed to broaden pharmacist participation on the multidisciplinary team. PMID- 29195732 TI - Does Treatment of the Tibia Matter in Bipolar Chondral Defects of the Knee? Clinical Outcomes with Greater Than 2 Years Follow-up. AB - PURPOSE: To compare the osteochondral allograft (OCA) outcomes of bipolar defects with isolated femoral defects and to investigate the optimal treatment of bipolar defects by comparing femoral OCA with tibial debridement to femoral OCA and tibial microfracture. METHODS: A series of patients with 2-year follow-up from March 2004 to September 2015 after femoral OCA for bipolar chondral defects was identified. Group 1 contained patients with tibial defects treated with debridement and group 2 contained patients with microfractured tibial defects. A third group (group 3) with isolated femoral defects treated with OCA was identified and matched by gender, body mass index (BMI), laterality, and OCA size to groups 1 and 2. Patient-specific, defect-specific, intraoperative, and postoperative data including patient-reported outcomes were collected on all patients. The study groups were compared using analyses of variance, paired sample t tests, and chi-square analyses. RESULTS: Thirty-six patients who had femoral OCA for bipolar lesions were identified with 20 patients in group 1 and 16 patients in group 2. Group 3 had 20 patients. There were no differences between the 3 groups in terms of gender (P = .616), BMI (P = .271), number of previous surgeries (P = .451), femoral or tibial defect size (P = .296), and OCA size (P = .981). Preoperative to postoperative patient-reported clinical outcomes (PROs) revealed statistical and clinically meaningful improvement in all 3 groups, but did not differ between groups. Patient-specific and defect-specific factors did not correlate with PROs. The graft survivorship for group 1 was 85% at 4.5 years, 100% for group 2 at 2.5 years, and 95% for group 3 at 3.8 years. CONCLUSIONS: Regardless of tibial treatment, patients with bipolar defects treated with femoral OCA have clinically meaningful improvements in PROs and excellent graft survivorship comparable to isolated femoral OCAs at more than 2 years. LEVEL OF EVIDENCE: Level III, case-control study. PMID- 29195733 TI - Changes in body mass index and mid-upper arm circumference in relation to all cause mortality in older adults. AB - BACKGROUND & AIMS: The assessment of weight loss as an indicator of poor nutritional status in older persons is currently widely applied to establish risk of mortality. Little is known about the relationship between changes in mid-upper arm circumference (MUAC) and mortality in older individuals. The aim of the present study was to examine the association between 3-year change in MUAC and 20 year mortality in community-dwelling older adults and compare this to the association between body mass index (BMI) change and mortality. METHODS: Data on changes in MUAC (cm) and BMI (kg/m2), covariates, and mortality were available for 1307 Dutch older adults (49.7% men) aged 65 years and older in 1995/96 (mean 75.6 years, SD 6.5) from Longitudinal Aging Study Amsterdam (LASA). Anthropometric measurements were performed in 1992/93 with repeated measurements in 1995/96 (baseline), and a mortality follow up until July 2015. BMI and MUAC change were divided into quintiles, with the quintile including zero defined as the reference category. Cox regression analyses were performed to examine the associations of 3-year changes in MUAC and BMI with subsequent 20-year all-cause mortality, adjusted for demographic and health factors. Age, sex and initial measurement of BMI and MUAC (1992/93) were tested for effect modification (P = <0.10). RESULTS: Mean baseline BMI was 26.7 kg/m2 (SD 4.2) with a 3-year change of -0.2 (SD 1.5). Mean baseline MUAC was 30.5 cm (SD 3.5) with a 3-year change of -0.8 (SD 1.6). Age, sex, and BMI and MUAC 3 years prior were effect modifiers in the associations between change in anthropometric measurement and mortality. Decrease in MUAC was not associated with mortality in persons with a higher initial MUAC (>=31 cm), while for persons with a lower initial MUAC, a decrease in MUAC of <=-2.15 was associated with increased mortality risk (HR 1.54; 95% CI: 1.14-2.09), also when further stratified on median age and sex. In stratified analysis of BMI change for median initial BMI (26.5) and additionally stratified for median age and sex, the associations between a BMI decrease of <=-1.19 and mortality fluctuated, mostly statistically not significant. No associations were found for gain in MUAC or BMI. CONCLUSIONS: Given that MUAC loss is more strongly and consistently associated with an increased mortality risk in older individuals with a low initial MUAC compared to BMI loss, this may be a more recommendable measure to use in clinical practice for assessing poor nutritional status, instead of weight loss. PMID- 29195734 TI - Discussion. PMID- 29195735 TI - Benefit of social media on patient engagement and satisfaction: Results of a 9 month, qualitative pilot study using Facebook. AB - BACKGROUND: Despite the potential benefits of social media, health care providers are often hesitant to engage patients through these sites. Our aim was to explore how implementation of social media may affect patient engagement and satisfaction. METHODS: In September 2016 a Facebook support group was created for liver transplant patients to use as a virtual community forum. Data including user demographics and group activity were reviewed. A survey was conducted evaluating users' perceptions regarding participation in the group. RESULTS: Over 9 months, 350 unique users (50% liver transplant patients, 36% caregivers/friends, 14% health care providers) contributed 339 posts, 2,338 comments, and 6,274 reactions to the group; 98% of posts were reacted to or commented on by other group members. Patients were the most active users compared with health care providers and caregivers. A total of 95% of survey respondents reported that joining the group had a positive impact on their care; and 97% reported that their main motivation for joining was to provide or receive support from other patients. CONCLUSION: This pilot study indicates that the integration of social media into clinical practice can empower surgeons to synthesize effectively a patient support community that augments patient engagement and satisfaction.

PMID- 29195736 TI - A novel reproducible model of aortic aneurysm rupture. AB - INTRODUCTION: Given the unknown biologic antecedents before aortic aneurysm rupture, the purpose of this study was to establish a reproducible model of aortic aneurysm rupture. METHODS: We fed 7-week-old apolipoprotein E deficient mice a high-fat diet for 4 weeks and osmotic infusion pumps containing Angiotensin II were implanted. Angiotensin II was delivered continuously for 4 weeks at either 1,000 ng/kg/min (n = 25) or 2,000 ng/kg/min (n = 29). A third group (n = 14) were given Angiotensin II at 2,000 ng/kg/min and 0.2% beta aminopropionitrile dissolved in drinking water. Surviving mice were killed 28 days after pump placement, aortic diameters were measured, and molecular analyses were performed. RESULTS: Survival at 28 days was significantly different among groups with 80% survival in the 1,000 ng/kg/min group, 52% in the 2,000 ng/kg/min group, and only 14% in the Angiotensin II/beta-aminopropionitrile group (P = .0001). Concordantly, rupture rates were statistically different among groups (8% versus 38% versus 79%, P < .0001). Rates of abdominal aortic aneurysm were 48%, 55%, and 93%, respectively, with statistically higher rates in the Angiotensin II/beta-aminopropionitrile group compared with both the 1,000 ng and 2,000 ng Angiotensin II groups (P = .006 and P = .0165, respectively). Rates of thoracic aortic aneurysm formation were 12%, 52%, and 79% in the 3 groups with a statistically higher rate in the Angiotensin II/beta-aminopropionitrile group compared with 1,000 ng group (P < .0001). CONCLUSIONS: A reproducible model of aortic aneurysm rupture was developed with a high incidence of abdominal and thoracic aortic aneurysm. This model should enable further studies investigating the pathogenesis of aortic rupture, as well as allow for targeted strategies to prevent human aortic aneurysm rupture. PMID- 29195738 TI - A perioperative care map improves outcomes in patients with morbid obesity undergoing major surgery. AB - BACKGROUND: The surgical management of patients with morbid obesity (body mass index >= 40) is notable for a relatively high risk of complications. To address this problem, a perioperative care map was developed using precautions and best practices commonly employed in bariatric surgery. It requires additional medical assessments, sleep apnea surveillance, more stringent guidelines for anesthetic management, and readily available bariatric operating room equipment, among other items. This care map was implemented in 2013 at 4 major urban teaching hospitals for use in patients undergoing all types of nonambulatory surgery with a body mass index greater than 40 kg/m2. The impact on patient outcomes was evaluated. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was used to compare 30-day outcomes of morbidly obese patients before the year 2013 and after the years 2015 care-map implementation. In addition, trends in 30-day outcomes for morbidly obese patients were compared with those for non-obese patients. RESULTS: Morbidly obese patients, between 2013 and 2015, saw an adjusted decrease in the rate of unplanned return to the operating room (OR = 0.49; P = .039), unplanned readmission (OR = 0.57; P = .006), total duration of stay (-0.87 days; P = .009), and postoperative duration of stay (-0.69 days; P = .007). Of these, total duration of stay (-0.86 days; P = .015), and postoperative duration of stay (-0.69 days; P = .012) improved significantly more for morbidly obese patients than for nonmorbidly obese patients. CONCLUSION: Outcomes in morbidly obese patients improved from 2013 to 2015. Implementation of a perioperative care map may have contributed to these improvements. The care map should be further investigated and considered for more widespread use. PMID- 29195739 TI - Comparison of 3D laparoscopic gastrectomy with a 2D procedure for gastric cancer: A phase 3 randomized controlled trial. AB - OBJECTIVE: To determine the relative safety and efficacy of 3D laparoscopic gastrectomy and 2D laparoscopic surgery in patients with gastric cancer. BACKGROUND: There is still a lack of randomized controlled trials regarding the safety and efficacy of 3D versus 2D laparoscopic surgery for gastric cancer. METHODS: A large-scale, phase 3, prospective, randomized controlled trial was conducted. (ClinicalTrials.gov number NCT02327481). RESULTS: A total of 438 patients were randomized (3D group: 219 cases; 2D group: 219 cases) between January 1, 2015, and April 1, 2016; 19 patients were excluded. Finally, data from 419 patients were analyzed (3D group: 211 cases; 2D group: 208 cases). There were no differences between the 2 groups regarding the operation time (3D versus 2D, 176 +/- 35 min vs. 174 +/- 33 min, P = .562). The intraoperative blood loss in the 3D group was somewhat less than in the 2D group (61 +/- 83 mL vs. 82 +/- 119 mL, P = .045). Further analysis suggested that the use of 3D laparoscopic surgery was a protective factor against excessive blood loss (>=200 mL). CONCLUSION: 3D laparoscopic gastrectomy did not shorten the operation time compared with 2D laparoscopic gastrectomy, but provided the benefit of less intraoperative blood loss and a lesser occurrence of excessive bleeding than the conventional 2D laparoscopic gastrectomy; the clinical value of the difference is limited. PMID- 29195741 TI - Ebola virus secreted glycoprotein decreases the anti-viral immunity of macrophages in early inflammatory responses. AB - During Ebola virus (EBOV) infection, secreted glycoprotein (sGP) is found in large quantities in the serum of both patients and infected animal models. It is thought to serve as a decoy for anti-EBOV antibodies. Using an in vitro model incorporating treatment of non-infected human THP-1 macrophages with recombinant EBOV sGP, this study sought to examine the impact of sGP upon key macrophage functions. Macrophage polarization and phagocytic capacity of activated macrophages were found to be unaltered by sGP treatment. However, treatment with sGP inhibited macrophage production of the pro-inflammatory cytokines TNFalpha and IL-6 while the yield of anti-inflammatory cytokine, IL-10, remained intact. Interestingly, the migratory ability of macrophages was also diminished by sGP, potentially due to a decrease in expression of CD11b, a vital macrophage integrin. Thus, EBOV sGP may operate to diminish functional contributions of non infected macrophages to increase the potential viral dissemination. PMID- 29195740 TI - Validation of fragility fractures in primary care electronic medical records: A population-based study. AB - PURPOSE: Electronic medical records databases use pre-specified lists of diagnostic codes to identify fractures. These codes, however, are not specific enough to disentangle traumatic from fragility-related fractures. We report on the proportion of fragility fractures identified in a random sample of coded fractures in SIDIAP. METHODS: Patients>=50 years old with any fracture recorded in 2012 (as per pre-specified ICD-10 codes) and alive at the time of recruitment were eligible for this retrospective observational study in 6 primary care centres contributing to the SIDIAP database (www.sidiap.org). Those with previous fracture/s, non-responders, and those with dementia or a serious psychiatric disease were excluded. Data on fracture type (traumatic vs fragility), skeletal site, and basic patient characteristics were collected. RESULTS: Of 491/616 (79.7%) patients with a registered fracture in 2012 who were contacted, 331 (349 fractures) were included. The most common fractures were forearm (82), ribs (38), and humerus (32), and 225/349 (64.5%) were fragility fractures, with higher proportions for classic osteoporotic sites: hip, 91.7%; spine, 87.7%; and major fractures, 80.5%. This proportion was higher in women, the elderly, and patients with a previously coded diagnosis of osteoporosis. CONCLUSIONS: More than 4 in 5 major fractures recorded in SIDIAP are due to fragility (non-traumatic), with higher proportions for hip (92%) and vertebral (88%) fracture, and a lower proportion for fractures other than major ones. Our data support the validity of SIDIAP for the study of the epidemiology of osteoporotic fractures. PMID- 29195742 TI - Preclinical models to assess the immunogenicity of AAV vectors. AB - Although gene transfer using adeno-associated virus (AAV) vectors has made tremendous progress in recent years, challenges remain due to vector-specific adaptive immune responses. Specifically, AAV-neutralizing antibodies reduce AAV transduction rates, while CD8+ T cells directed to AAV capsid antigens cause rejection of AAV-transduced cells. This has been addressed clinically by excluding humans with pre-existing AAV-neutralizing antibodies from gene transfer trials or by using immunosuppression or reduced doses of vectors expressing improved transgene products to blunt or circumvent destructive T cell responses. Although these approaches have met with success for treatment of some diseases, most notably hemophilia B, they may not be suitable for others. Pre-clinical models are thus needed to test alternative options to sidestep pre-existing AAV neutralizing antibodies, to prevent their induction following gene transfer and to block the detrimental effects of CD8+ T cells directed to AAV capsid antigens. This chapter describes some of the available, although not yet perfect, models that can assess immune responses to AAV gene transfer.

PMID- 29195744 TI - Discrimination of atypical parkinsonisms with transcranial magnetic stimulation. AB - BACKGROUND: Differential diagnosis of atypical parkinsonian disorders, i.e. dementia with Lewy bodies (DLB), progressive supranuclear palsy (PSP) or corticobasal syndrome (CBS) still remains problematic. Furthermore, DLB may overlap with Alzheimer's disease (AD) in the early stages of disease. OBJECTIVE: To determine whether transcranial magnetic stimulation (TMS) can be used to classify atypical parkinsonian disorders and AD. METHODS: A paired-pulse TMS multi-paradigm approach assessing multiple intracortical circuits, as short interval intracortical inhibition-facilitation and short latency afferent inhibition, was used to model a decision tree analysis and determine diagnostic accuracy in classifying different neurodegenerative disorders. RESULTS: We observed a significant impairment in short latency afferent inhibition in AD and DLB and a significant impairment in short interval intracortical inhibition facilitation in DLB, PSP and CBS patients. These parameters were used to model a decision tree analysis which yielded an overall diagnostic accuracy of 88.3%, with 90.5% for AD, 85.2% for DLB, 76.0% for CBS-PSP, and 94.9% for healthy controls. CONCLUSIONS: The assessment of intracortical connectivity with TMS may aid in the differential diagnosis of AD and the atypical parkinsonian disorders.

AB - BACKGROUND: While transnational migration has been shown to be a risk factor for schizophrenia, studies have not examined whether massive internal rural-to-urban migration in China in recent years has increased the risk of hospitalization for schizophrenia, or schizophrenia symptom severity among migrants. METHOD: In a sample of patients acutely hospitalized with schizophrenia in Changsha, Hunan Province, China (N=334), the proportion of past migrant workers among patients was compared to the proportion of past migrant workers in the general adult population of Hunan. Past migrants were also compared to non-migrants on age of onset, and on symptom severity using the Positive and Negative Syndrome Scale (PANSS). The risk ratio for being a migrant among those hospitalized for schizophrenia was stratified by age and gender subgroups. Multiple regression analysis was used to evaluate group differences in age of onset and symptoms. RESULTS: Of 334 patients diagnosed with schizophrenia hospitalized for <180days, 150 (44.9%) were identified as having been migrant workers compared to 31.0% in the general adult population of Hunan for a risk ratio of 1.45, a risk that was higher for women (2.19) than for men (1.09). Migrant workers also had higher scores than others on total PANSS symptoms. CONCLUSION: Migrant workers appear to be at greater risk of hospitalization for schizophrenia than other residents of Hunan and showed more severe psychopathology. These findings may reflect specific lack of health insurance coverage for workers migrating to non-native provinces in China, thereby delaying access to treatment.

AB - A new processing method for echocardiographic particle image velocimetry (EchoPIV) using moving ensemble (ME) correlation with dynamic phase correlation filtering was developed to improve velocity measurement accuracy for routine clinical evaluation of cardiac function. The proposed method was tested using computationally generated echocardiogram images. Error analysis indicated that ME EchoPIV yields a twofold improvement in bias and random error over the current standard correlation method (betaPairwise = -0.15 vs. betaME = -0.06; sigmaPairwise = 1.00 vs. sigmaME = 0.49). Subsequently a cohort of eight patients with impaired diastolic filling underwent similar evaluation. Comparison of patient EchoPIV velocity time series with corresponding color M-mode velocity time series revealed better agreement for ME EchoPIV compared with standard PIV processing (RME = 0.90 vs. RPairwise = 0.70). Further time series analysis was performed to measure filling propagation velocity and 1-D intraventricular pressure gradients. Comparison against CMM values indicated that both measurements are completely decorrelated for pairwise processing (R2Vp = 0.15, R2IVPD = 0.07), whereas ME processing correlates decently (R2Vp = 0.69, R2IVPD = 0.69). This new approach enables more robust processing of routine clinical scans and can increase the utility of EchoPIV for the assessment of left ventricular function.

AB - Ultrasound is widely used in the diagnosis and follow-up of chronic arthritis. We present an evaluation of a novel automatic ultrasound diagnostic tool based on image recognition technology. Methods used in developing the algorithm are described elsewhere. For the purpose of evaluation, we collected 140 ultrasound images of metacarpophalangeal and proximal interphalangeal joints from patients with chronic arthritis. They were classified, according to hypertrophy size, into four stages (0-3) by three independent human observers and the algorithm. An agreement ratio was calculated between all observers and the standard derived from results of human staging using kappa statistics. Results was significant in all pairs, with the highest p value of 3.9 * 10-6. kappa coefficients were lower in algorithm/human pairs than between human assessors. The algorithm is effective in staging synovitis hypertrophy. It is, however, not mature enough to use in a daily practice because of limited accuracy and lack of color Doppler recognition. These limitations will be addressed in the future. PMID- 29195753 TI - Ultrasound Determination of the Femoral Head-Neck Alpha Angle. AB - The femoral head-neck alpha angle is used to quantify the degree of femoral head asphericity in patients suspected of cam-type femoroacetabular impingement. The measurement was first performed using magnetic resonance imaging and, more recently, three-dimensional computed tomography (CT). We set out to determine whether the alpha angle could be reliably measured using ultrasound. Patients were recruited from a cohort presenting for CT of the hip. Alpha angles were calculated following the departmental protocol by institutionally accredited radiographers. After the CT, patients were imaged with ultrasound and the alpha angle calculated from the ultrasound image by a sonographer blinded to the CT result. Statistical comparison of the two methods was performed with the Bland Altman test using SPSS (version 21.0, Chicago, USA), and a p < 0.05 afforded significance. Twenty-eight patients were recruited. Eleven patients were bilateral examinations, providing 39 hips for analysis. There were 15 females and 13 males, with 21 right and 18 left hips examined. Average patient age (+/ standard deviation) was 40 y (+/-13.9 y). Mean (+/-standard deviation) measurements for CT and ultrasound were 62.5 degrees (+/-14.2 degrees ) and 64.5 degrees (+/-12.6 degrees ), respectively. The mean absolute difference between the two methods was 10.5 degrees (95% confidence interval 6.9 degrees -14.0 degrees ). Sensitivity of each individual ultrasound measurement was 91.3%. The specificity of ultrasound was 43.75%. The positive predictive value was 0.7, and the negative predictive value was 0.78. Overall accuracy of the ultrasound derived alpha angle was calculated at 0.718. Ultrasound demonstrates good sensitivity and good negative predictive value in calculation of the femoral head neck alpha angle compared with CT; however, specificity is low. Ultrasound measurement of the alpha angle can provide objective evidence of cam-type femoroacetabular impingement in symptomatic patients and can direct patients to more established imaging techniques where appropriate.

AB - A method to determine acoustic cavitation probabilities in tissue-mimicking materials (TMMs) is described that uses a high-intensity focused ultrasound (HIFU) transducer for both inducing and detecting the acoustic cavitation events. The method was evaluated by studying acoustic cavitation probabilities in agar based TMMs with and without scatterers and for different sonication modes like continuous wave, single pulses (microseconds to milliseconds) and repeated burst signals. Acoustic cavitation thresholds (defined here as the peak rarefactional in situ pressure at which the acoustic cavitation probability reaches 50%) at a frequency of 1.06 MHz were observed between 1.1 MPa (for 1 s of continuous wave sonication) and 4.6 MPa (for 1 s of a repeated burst signal with 25-cycle burst length and 10-ms burst period) in a 3% (by weight) agar phantom without scatterers. The method and its evaluation are described, and general terminology useful for standardizing the description of insonation conditions and comparing results is provided. In the accompanying second part, the presented method is used to systematically study the acoustic cavitation thresholds in the same material for a range of sonication modes. PMID- 29195755 TI - Determination of Acoustic Cavitation Probabilities and Thresholds Using a Single Focusing Transducer to Induce and Detect Acoustic Cavitation Events: II. Systematic Investigation in an Agar Material. AB - In the accompanying article (Part I), a method is described to determine acoustic cavitation probabilities in tissue-mimicking materials (TMMs) using a high intensity focused ultrasound (HIFU) transducer for both inducing and detecting the acoustic cavitation events, and its suitability for different sonication modes like continuous wave, single pulses (with pulse lengths from microseconds to milliseconds) and repeated burst signals is discussed. In Part II, the use of the method for a systematic study of the dependence of the acoustic cavitation thresholds in 3% (by weight) agar phantoms on the temporal sonication parameters is discussed. The values obtained at a frequency of 1.06 MHz, ranging from (0.58 +/- 0.12) MPa for a 3-s continuous wave mode sonication to (5.2 +/- 1.0) MPa for single shots with a length of 10 wave cycles, are discussed and interpreted on the basis of literature values and their self-consistency. PMID- 29195757 TI - Bowel Sonoelastography in Patients with Crohn's Disease: A Systematic Review. AB - Sonoelastography is an ultrasound-based method for evaluating the biological properties of a target tissue. It is commonly used in the diagnosis of liver and thyroid disease, but recently its use for monitoring the characteristics of bowel wall in patients affected by Crohn's disease (CD) has been proposed. Our aim was a systematic review of the use of sonoelastography in patients with CD. An initial database search retrieved 32 possible articles. On initial screening, 7 articles, concerning a total of 129 patients and 154 lesions of the small and large bowel, were finally included in the review. The age range varied between 6 and 53 y, and disease duration ranged between 1 and 623 mo. We collected data on the examinations performed (type and time), bowel area considered and parameters evaluated. All authors found that elastography correlates well with the degree of fibrosis, as wall strain significantly decreases in segments affected by fibrotic stenosis. Even though the endpoints proposed in the various articles are relatively inhomogeneous and scarcely comparable, we found that sonoelastography is a promising tool in the evaluation of patients with CD as it can differentiate inflammatory and fibrotic strictures in small case series. PMID- 29195756 TI - An Ultrasound Surface Wave Technique for Assessing Skin and Lung Diseases. AB - Systemic sclerosis (SSc) is a multi-organ connective tissue disease characterized by immune dysregulation and organ fibrosis. Severe organ involvement, especially of the skin and lung, is the cause of morbidity and mortality in SSc. Interstitial lung disease (ILD) includes multiple lung disorders in which the lung tissue is fibrotic and stiffened. The purpose of this study was to translate ultrasound surface wave elastography (USWE) for assessing patients with SSc and/or ILD via measuring surface wave speeds of both skin and superficial lung tissue. Forty-one patients with both SSc and ILD and 30 healthy patients were enrolled in this study. An external harmonic vibration was used to generate the wave propagation on the skin or lung. Three excitation frequencies of 100, 150 and 200 Hz were used. An ultrasound probe was used to measure the wave propagation in the tissue non-invasively. Surface wave speeds were measured on the forearm and upper arm of both left and right arm, as well as the upper and lower lungs, through six intercostal spaces of patients and healthy patients. Viscoelasticity of the skin was calculated by the wave speed dispersion with frequency using the Voigt model. The magnitudes of surface wave speed and viscoelasticity of patients' skin were significantly higher than those of healthy patients (p <0.0001) for each location and each frequency. The surface wave speeds of patients' lung were significantly higher than those of healthy patients (p <0.0001) for each location and each frequency. USWE is a non-invasive and non ionizing technique for measuring both skin and lung surface wave speed and may be useful for quantitative assessment of SSc and/or ILD.

Cortical hemodynamic responses measured by functional Near Infrared Spectroscopy (fNIRS): Special Section on "Translational and Neuroscience Studies in Affective Disorders" Section Editor, Maria Nobile MD, PhD. This Section of JAD focuses on the relevance of translational and neuroscience studies in providing a better understanding of the neural basis of affective disorders. The main aim is to briefly summarise relevant research findings in clinical neuroscience with particular regards to specific innovative topics in mood and anxiety disorders. AB - BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by deficits in cognitive and emotional self-control. Optical technique acquisitions, such as near infrared spectroscopy (NIRS), seem to be very promising during developmental ages, as they are non- invasive techniques and less influenced by body movements than other neuroimaging methods. Recently, these new techniques are being widely used to measure neural correlates underlying neuropsychological deficits in children with ADHD. METHODS: In a short series of articles, we will review the results of functional NIRS (fNIRS) studies in children with ADHD. The present brief review will focus on the results of the fNIRS studies that investigate cortical activity during neuropsychological and/or emotional tasks. RESULTS: According to the reviewed studies, children and adolescents with ADHD show peculiar cortical activation both during neurological and emotional tasks, and the majority of the reviewed studies revealed lower prefrontal cortex activation in patients compared to typically developmental controls. LIMITATIONS: a consistent interpretation of these results is limited by the substantial methodological heterogeneity including patients' medication status and washout period, explored cerebral regions, neuropsychological tasks, number of channels and sampling temporal resolutions. CONCLUSIONS: fNIRS seems to be a promising tool for investigating neural substrates of emotional dysregulation and executive function deficits in individuals with ADHD during developmental ages.

AB - This paper examined knowledge about the health effects of smoking among health equity groups following the 2012 introduction of refreshed pictorial health warning labels (HWLs) in Canada. Data are from the 2012/2013 Youth Smoking Survey a representative school-based survey of 47,203 adolescents in Grades 6-12 in nine provinces. Regression models examined overall knowledge about eight health effects of smoking included in the HWLs. Less than one-third of adolescents (32.2%) knew that smoking causes vision loss/blindness and 33.7% knew that smoking causes bladder cancer. Whereas knowledge was high for lung cancer (93.9%), knowledge about other health effects ranged from 52.9% for chronic bronchitis/emphysema to 77.6% for gum or mouth disease. Non-smoking adolescents who were: susceptible to future smoking, male, ethnic minorities, and who had less spending money were significantly less likely to be knowledgeable of the health effects of smoking. There were fewer disparities in knowledge about the health effects of smoking among smokers. Smokers who bought loose or bagged cigarettes rather than cigarettes in packages or cartons were significantly less likely to be knowledgeable about the health effects of smoking. There are significant disparities in knowledge about the health effects of smoking by health equity groups particularly among non-smoking adolescents. Warning labels have the potential to reduce disparities in knowledge about the health effects of smoking when exposure to the warning labels is universal. Complementary strategies such as mass media campaigns are needed to address disparities in knowledge. PMID- 29195761 TI - Neighbourhood typologies and associations with body mass index and obesity: A cross-sectional study. AB - Little research has investigated associations between a combined measure of the food and physical activity (PA) environment, BMI (body-mass-index) and obesity. Cross-sectional data (n=22,889, age 18-86years) from the Yorkshire Health Study were used [2010-2013]. BMI was calculated using self-reported height and weight; obesity=BMI>=30. Neighbourhood was defined as a 2km radial buffer. Food outlets and PA facilities were sourced from Ordnance Survey Points of Interest (PoI) and categorised into 'fast-food', 'large supermarkets', 'convenience and other food retail outlets' and 'physical activity facilities'. Parks were sourced from Open Street Map. Latent class analysis was conducted on these five environmental variables and availability was defined by quartiles of exposure. Linear and logistic regressions were then conducted for BMI and obesity respectively for different neighbourhood types. Models adjusted for age, gender, ethnicity, area level deprivation, and rural/urban classification. A five-class solution demonstrated best fit and was interpretable. Neighbourhood typologies were defined as; 'low availability', 'moderate availability', 'moderate PA, limited food', 'saturated' and 'moderate PA, ample food'. Compared to low availability, one typology demonstrated lower BMI (saturated, b=-0.50, [95% CI=-0.76, -0.23]), while three showed higher BMI (moderate availability, b=0.49 [0.27, 0.72]; moderate PA, limited food, b=0.30 [0.01, 0.59]; moderate PA, ample food, b=0.32 [0.08, 0.57]). Furthermore, compared to the low availability, saturated neighbourhoods showed lower odds of obesity (OR=0.86 [0.75, 0.99]) while moderate availability showed greater odds of obesity (OR=1.18 [1.05, 1.32]). This study supports population-level approaches to tackling obesity however neighbourhoods contained features that were health-promoting and -constraining.

AB - PURPOSE: This paper describes the Working to Institutionalize Sex Education (WISE) Initiative, a privately funded effort to support ready public school districts to advance and sustain comprehensive sexuality programs, and examines the degree to which WISE has been successful in increasing access to sex education, removing barriers, and highlighting best practices. METHODS: The data for this study come from a set of performance indicators, guidance documents, and tools designed for the WISE Initiative to capture changes in sex education institutionalization at WISE school districts. The evaluation includes the analysis of 186 school districts across 12 states in the U.S. RESULTS: As a result of the WISE Initiative, 788,865 unique students received new or enhanced sex education in school classrooms and 88 school districts reached their sex education institutionalization goals. In addition to these school district successes, WISE codified the WISE Method and toolkit-a practical guide to help schools implement sex education. CONCLUSIONS: Barriers to implementing sexuality education can be overcome with administrative support and focused technical assistance and training, resulting in significant student reach in diverse school districts nationwide. PMID- 29195759 TI - Circadian regulation of glucose, lipid, and energy metabolism in humans. AB - The circadian system orchestrates metabolism in daily 24-hour cycles. Such rhythms organize metabolism by temporally separating opposing metabolic processes and by anticipating recurring feeding-fasting cycles to increase metabolic efficiency. Although animal studies demonstrate that the circadian system plays a pervasive role in regulating metabolism, it is unclear how, and to what degree, circadian research in rodents translates into humans. Here, we review evidence that the circadian system regulates glucose, lipid, and energy metabolism in humans. Using a range of experimental protocols, studies in humans report circadian rhythms in glucose, insulin, glucose tolerance, lipid levels, energy expenditure, and appetite. Several of these rhythms peak in the biological morning or around noon, implicating earlier in the daytime is optimal for food intake. Importantly, disruptions in these rhythms impair metabolism and influence the pathogenesis of metabolic diseases. We therefore also review evidence that circadian misalignment induced by mistimed light exposure, sleep, or food intake adversely affects metabolic health in humans. These interconnections among the circadian system, metabolism, and behavior underscore the importance of chronobiology for preventing and treating type 2 diabetes, obesity, and hyperlipidemia. PMID- 29195763 TI - Revisiting the Link Between Depression Symptoms and High School Dropout: Timing of Exposure Matters. AB - PURPOSE: Recent reviews concluded that past depression symptoms are not independently associated with high school dropout, a conclusion that could induce schools with high dropout rates and limited resources to consider depression screening, prevention, and treatment as low-priority. Even if past symptoms are not associated with dropout, however, it is possible that recent symptoms are. The goal of this study was to examine this hypothesis. METHODS: In 12 disadvantaged high schools in Montreal (Canada), all students at least 14 years of age were first screened between 2012 and 2015 (Nscreened = 6,773). Students who dropped out of school afterward (according to school records) were then invited for interviews about their mental health in the past year. Also interviewed were matched controls with similar risk profiles but who remained in school, along with average not at-risk schoolmates (Ninterviewed = 545). Interviews were conducted by trained graduate students. RESULTS: Almost one dropout out of four had clinically significant depressive symptoms in the 3 months before leaving school. Adolescents with recent symptoms had an odd of dropping out more than twice as high as their peers without such symptoms (adjusted odds ratio = 2.17; 95% confidence interval = 1.14-4.12). In line with previous findings, adolescents who had recovered from earlier symptoms were not particularly at risk. CONCLUSIONS: These findings suggest that to improve disadvantaged youths' educational outcomes, investments in comprehensive mental health services are needed in schools struggling with high dropout rates, the very places where adolescents with unmet mental health needs tend to concentrate. PMID- 29195764 TI - Suicide Screening in Primary Care: Use of an Electronic Screener to Assess Suicidality and Improve Provider Follow-Up for Adolescents. AB - PURPOSE: The purpose of this study was to assess the feasibility of using an existing computer decision support system to screen adolescent patients for suicidality and provide follow-up guidance to clinicians in a primary care setting. Predictors of patient endorsement of suicidality and provider documentation of follow-up were examined. METHODS: A prospective cohort study was conducted to examine the implementation of a CDSS that screened adolescent patients for suicidality and provided follow-up recommendations to providers. The intervention was implemented for patients aged 12-20 years in two primary care clinics in Indianapolis, Indiana. RESULTS: The sample included 2,134 adolescent patients (51% female; 60% black; mean age = 14.6 years [standard deviation = 2.1]). Just over 6% of patients screened positive for suicidality. A positive endorsement of suicidality was more common among patients who were female, depressed, and seen by an adolescent-medicine board-certified provider as opposed to general pediatric provider. Providers documented follow-up action for 83% of patients who screened positive for suicidality. Documentation of follow-up action was correlated with clinic site and Hispanic race. The majority of patients who endorsed suicidality (71%) were deemed not actively suicidal after assessment by their provider. CONCLUSIONS: Incorporating adolescent suicide screening and provider follow-up guidance into an existing computer decision support system in primary care is feasible and well utilized by providers. Female gender and depressive symptoms are consistently associated with suicidality among adolescents, although not all suicidal adolescents are depressed. Universal use of a multi-item suicide screener that assesses recency might more effectively identify suicidal adolescents. PMID- 29195765 TI - Central nervous system blastomycosis diagnosed using the MVista(r) Blastomyces quantitative antigen enzyme immunoassay test on cerebrospinal fluid: A case report and review of the literature. AB - Blastomyces dermatitidis is a thermally dimorphic fungus that is capable of causing pulmonary and extra-pulmonary disease, including infections of the central nervous system (CNS). Diagnosis of CNS blastomycosis with non-invasive testing can be difficult, and a surgical biopsy may ultimately be required for microbiological and/or histopathological confirmation. A case of B. dermatitidis meningitis is presented where the diagnosis was made by testing cerebrospinal fluid (CSF) using the MVista(r) Blastomyces Quantitative Antigen Enzyme Immunoassay test. The utility of performing this test on CSF for diagnosis of CNS mass lesions/abscesses caused by B. dermatitidis in the absence of associated meningitis remains unclear. Cross reaction of the Blastomyces antigen test with other dimorphic fungi is a concern, necessitating that positive test results are interpreted in the context of the patient's exposure and travel history. PMID- 29195766 TI - Dalbavancin is active in vitro against biofilms formed by dalbavancin-susceptible enterococci. AB - We tested the in vitro activity of dalbavancin, vancomycin and daptomycin against 83 enterococcal isolates in planktonic and biofilm states. The MIC90 for vancomycin-susceptible Enterococcus faecalis was 0.125 and 4MUg/mL for dalbavancin and daptomycin, respectively. For vancomycin-resistant Enterococcus faecium, the MIC90 was >16 and 2MUg/mL for dalbavancin and daptomycin, respectively. Dalbavancin minimum biofilm inhibitory concentrations (MBICs) for vancomycin-susceptible and -resistant isolates were <=0.25 and >16MUg/mL, respectively. The daptomycin MBIC90 for all isolates was 4MUg/mL. For E. faecalis and E. faecium, dalbavancin minimum biofilm bactericidal concentrations (MBBCs) for vancomycin-susceptible and -resistant isolates were <=4 and >16MUg/mL, respectively, whereas vancomycin MBBCs were >128MUg/mL for all isolates, and daptomycin MBBC90 values for both species were 128MUg/mL. In summary, dalbavancin exhibited in vitro activity against all tested isolates of vancomycin susceptible, but not against vancomycin-resistant enterococci; activity was observed in both the planktonic and biofilm states.

AB - Prolonged exposure to a disturbance such as a toxicant has the potential to result in rapid evolution to toxicant resistance in many short-lived species such as daphniids. This evolution may allow a population to persist at higher levels of the toxicant than is possible without evolution. Here we apply evolutionary game theory to a Leslie matrix model for a daphniid population to obtain a Darwinian model that couples population dynamics with the dynamics of an evolving trait. We use the Darwinian model to consider how the evolution of resistance to the lethal or sublethal effects of a disturbance may change the population dynamics. In particular, we determine the conditions under which a daphniid population can persist by evolving toxicant resistance. We then consider the implications of this evolution in terms of the use of daphniids as surrogate species. We show for three species of daphniids that evolution of toxicant resistance means that one species may persist while another does not. These results suggest that toxicant studies that do not consider the potential of a species (or its surrogate) to develop toxicant resistance may not accurately predict the long term persistence of the species. PMID- 29195773 TI - Cognitive deficits in bipolar disorders: Implications for emotion. AB - Prominent cognitive deficits have been documented in bipolar disorder, and multiple studies suggest that these deficits can be observed among non-affected first-degree relatives of those with bipolar disorder. Although there is variability in the degree of cognitive deficits, these deficits are robustly relevant for functional outcomes. A separate literature documents clear difficulties in emotionality, emotion regulation, and emotion-relevant impulsivity within bipolar disorder, and demonstrates that these emotion-relevant variables are also central to outcome. Although cognitive and emotion domains are typically studied independently, basic research and emergent findings in bipolar disorder suggest that there are important ties between cognitive deficits and the emotion disturbances observed in bipolar disorder. Understanding these relationships has relevance for fostering more integrative research, for clarifying relevant aspects related to functionality and vulnerability within bipolar disorder, and for the development of novel treatment interventions. Bipolar disorder (BD) is a severe psychiatric illness that has been ranked as one of the 20 leading medical causes of disability (WHO, 2011). BD has been shown to be the psychiatric disorder with the highest rates of completed suicide across two major cohort studies (Ilgen et al., 2010; Nordentoft, Mortensen, & Pedersen, 2011). In a cross-national representative sample, one in four persons diagnosed with bipolar I disorder reported a suicide attempt (Merikangas et al., 2011). Rates of relapse remain high despite available treatments (Gitlin, Swendsen, Heller, & Hammen, 1995), and in the year after hospitalization for manic episode, two-thirds of patients do not return to work (Strakowski et al., 1998). Poverty, homelessness, and incarceration are all too common (Copeland et al., 2009). Despite the often poor outcomes, there is also evidence for outstanding accomplishments and creativity among those with milder forms of the disorder and their family members (Coryell et al., 1989; Jamison, 1993; Murray & Johnson, 2010). Some individuals appear to achieve more than the general population, suggesting the importance of understanding the variables that predict differential outcome within bipolar disorder. Within this paper, we focus on two key predictors of outcomes within bipolar disorder: cognition and emotionality. We review evidence that problems in cognition and emotionality are prominent among those diagnosed with the disorder, are not artifacts of symptom state, and relate substantively to poorer outcomes. Although traditionally studied separately, new work points toward the idea that cognition and emotionality are intricately linked within bipolar disorder. Drawing from research within bipolar disorder as well as outside of bipolar disorder, we build a model of how cognition and emotionality might be tied within bipolar disorder. We then provide suggestions for future research. Before considering findings, it is worth noting that there are several forms of the disorder, defined by varying degrees and duration of manic symptoms (APA, 2013; WHO, 1993). Manic episodes are defined by abnormally elevated or irritable mood, accompanied by increased activity and at least three symptoms (four if mood is only irritable) such as decreased need for sleep, increased self-confidence, racing thoughts or flight of ideas, rapid speech, distractibility, goal-directed activity, and engagement in pleasurable activities without regard to potential negative consequences. To meet criteria for mania, these symptoms must persist for at least one week or require hospitalization, and must lead to difficulties with functioning. If functional impairment is not more than mild and duration is between 4 and 6 days, the episode is considered a hypomanic episode. Bipolar I disorder (BD I) is diagnosed on the basis of at least one lifetime manic episode within the DSM-5 and by at least two episodes within the ICD, whereas bipolar II disorder is diagnosed on the basis of at least one hypomanic episode (and no manic episodes) as well as major depressive episodes. Cyclothymic disorder is defined by chronic but milder fluctuations between manic and depressive symptoms. Most research focuses on BD I. In addition to diagnosed samples, research has focused on those at high risk for bipolar disorder, including first-degree relatives of those with BD. This work draws on the evidence for extremely high heritability of BD I, with estimates from community-based twin studies of 0.85 (Kieseppa, Partonen, Haukka, Kaprio, & Lonnqvist, 2014). Other research has considered high risk for BD by virtue of lifetime subsyndromal symptoms, as measured by scales such as the Hypomanic Personality Scale (Eckblad & Chapman, 1986) or the General Behavior Inventory (Depue, Krauss, Spoont, & Arbisi, 1989). The study of high-risk individuals provides a way to decipher whether deficits are present before the onset of the disorder, of importance given models suggesting that episodes of the disorder may change brain function (Chang, Steiner, & Ketter, 2000; Strakowski, 2012) as well as individuals' perceptions of their emotion regulation. Beyond defining BD, it is worth defining some of the many different neuropsychological tasks that have been widely studied in BD. Perhaps no area has received more attention than executive function. Executive function is related to three core functions: 1) inhibition, the ability to suppress irrelevant information in working memory in order to accomplish an established goal; 2) working memory, the ability to hold and manipulate information in mind; and 3) cognitive flexibility, the ability to shift strategies in response to feedback (Diamond, 2013; Miyake et al., 2000). Attention (defined as the process of selecting information reception from internal or external cues) is implicated in all three of these aspects of executive function. Much of the literature we will discuss focuses on response inhibition, or the ability to suppress a prepotent response, which is considered a subtype of inhibition. Some tests measure multiple facets of executive function; for example the Trails B test likely requires working memory and cognitive flexibility (Sanchez-Cubillo et al., 2009). Aside from executive function, multiple other facets of cognition have been widely studied in bipolar disorder. Verbal and non-verbal memory are related to the ability to register, store and retrieve verbal or visual information (Lezak, 1995). Verbal fluency is measured as the number of verbal responses a person can generate to a given target, such as a specific semantic category (e.g., animals, furniture) or phonetic category (e.g., words that begin with letter F) (Diamond, 2013). Although cognitive tasks have been designed to evaluate these specific functions, it is important to note that most measures are highly inter-correlated and may assess multiple overlapping functions to some extent (for example, the Trails B test is often described as an "executive function" task, although this task likely involves both working memory and cognitive flexibility. Not surprisingly, then, some authors label the function of certain tests differently, and this is particularly evident in meta-analyses of cognition. As we describe findings in this paper, we will use the terms proposed by the authors but will also identify key tests used to define a cognitive construct. With this background in mind, we turn to a discussion of cognitive deficits, then of emotion-related traits. Our hope is that those concise summaries provide evidence for the importance of both domains, but also specificity regarding the facets of emotion and cognition that are most impaired in BD. This specificity then guides our consideration of models that integrate cognition and emotion. PMID- 29195775 TI - Re: Follow-up of Prostatectomy Versus Observation for Early Prostate Cancer. PMID- 29195774 TI - Paving TRAIL's Path with Ubiquitin. AB - Despite its name, signalling induced by the tumour necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is versatile. Besides eliciting cell death by both apoptosis and necroptosis, TRAIL can also induce migration, proliferation, and cytokine production in cancerous and non-cancerous cells. Unravelling the mechanisms regulating the intricate balance between these different outputs could therefore facilitate our understanding of the role of TRAIL in tissue homeostasis, immunity, and cancer. Ubiquitination and its reversal, deubiquitination, are crucial modulators of immune receptor signalling. This review discusses recent progress on the orchestration of TRAIL signalling outcomes by ubiquitination of various components of the signalling complexes, our understanding of the molecular switches that decide between cell death and gene activation, and what remains to be discovered.

PMID- 29195777 TI - Multiparametric Magnetic Resonance Imaging Is an Independent Predictor of Salvage Radiotherapy Outcomes After Radical Prostatectomy. AB - BACKGROUND: The Stephenson nomogram is widely used to estimate the success of salvage radiotherapy (sXRT) for prostate cancer (PCa) recurrence after radical prostatectomy (RP). OBJECTIVE: To determine whether multiparametric pelvic magnetic resonance imaging (mpMRI) performed for biochemical recurrence after RP improves prognostication of sXRT relative to the Stephenson nomogram. DESIGN, SETTING, AND PARTICIPANTS: Men undergoing RP at our institution from 2003 to 2012 who had biochemical recurrence evaluated by mpMRI within 12 mo of sXRT were retrospectively reviewed. Exclusion criteria included PCa treatment prior to RP, adjuvant XRT after RP, salvage cryotherapy before sXRT, and hormone refractory disease prior to sXRT. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Multivariable Cox regression analyses (adjusting for Stephenson nomogram covariates) associated mpMRI findings with prostate-specific antigen (PSA) recurrence and metastasis after sXRT. The mpMR images were compared in a binary fashion: no lesion versus vesicourethral/seminal vesical bed/prostate fossa lesions. RESULTS AND LIMITATIONS: Among 473 sXRT patients, 57%(204) had lesions on mpMRI: 26%(124) vesicourethral, 28%(135) seminal vesical bed/prostatic fossa, 7%(34) nodal, and 1%(3) bone. Median PSA at mpMRI with lesions was 0.46 versus 0.40ng/ml without lesions. After excluding nodal/bone lesions, 29% of men developed PSA recurrence and 14% metastasis (median follow-up 45 mo after sXRT). For patients with a pre-sXRT PSA of <=0.5ng/ml, negative mpMRI was associated with increased PSA recurrence (39% vs 12%, p<0.01) and metastasis (16% vs 2%, p<0.01) at 4 yr after sXRT. For patients with a PSA of <=0.5ng/ml, the addition of mpMRI to the propensity score (created using variables from the original Stephenson nomogram) improved the c-statistic from 0.71 to 0.77 for PSA recurrence (hazard ratio [HR] 3.60, p<0.01) and from 0.66 to 0.77 for metastasis (HR 6.68, p<0.01). Limitations include evolutions in MRI technique and lack of a cohort of men undergoing mpMRI electing against sXRT. CONCLUSIONS: Pre-sXRT mpMRI improves clinicopathologic variables to estimate sXRT success, particularly in the early sXRT setting. PATIENT SUMMARY: Men who have biochemically recurrent prostate cancer after radical prostatectomy often receive salvage radiotherapy. In our study, multiparametric pelvic magnetic resonance imaging prior to salvage radiotherapy was a significant predictor of prostate-specific antigen failure and metastasis after radiotherapy. PMID- 29195778 TI - Epidemiology and risk factors for Clostridium difficile-associated diarrhea in adult inpatients in a university hospital in China. AB - BACKGROUND: Clostridium difficile-associated diarrhea (CDAD) is an important disease with rising incidence and mortality in western countries. However, studies about CDAD in China are limited. The aims of this study are to investigate the epidemiology and risk factors of CDAD in a university hospital located in Eastern China. METHODS: Diarrhea samples of all adult inpatients were collected for C difficile culture prospectively from August 2013-April 2014. Suspected colonies were identified by biochemical identification cards. Confirmed C difficile isolates were further analyzed for the presence of toxin genes and typed by polymerase chain reaction ribotyping. Patient demographics, presumed risk factors, clinical manifestations, and laboratory findings were collected through inpatient medical record systems retrospectively. RESULTS: In total, 45 stains of toxigenic C difficile were isolated from 315 nonrepetitive diarrhea samples. The isolation rate was 14.29% (45/315). No RT027/ST1 strain was found. An outbreak of CDAD occurred in the digestive ward and was finally found to be caused by ST35 strains during this study. Coloclysis and diabetes were found to be independent risk factors of CDAD, besides the common risk factors previously reported. CONCLUSIONS: CDAD is not uncommon in Chinese hospitals. C difficile ST35 as a new strain causing outbreaks should be noticed. Coloclysis and diabetes are new independent risk factors for CDAD, and further study is needed. PMID- 29195779 TI - Implementation of remote video auditing with feedback and compliance for manual cleaning protocols of endoscopic retrograde cholangiopancreatography endoscopes. AB - A pilot initiative to assess the use of remote video auditing in monitoring compliance with manual-cleaning protocols for endoscopic retrograde cholangiopancreatography (ERCP) endoscopes was performed. Compliance with manual cleaning steps following the initiation of feedback was measured. A video feed of the ERCP reprocessing room was provided to remote auditors who scored items of an ERCP endoscope manual-cleaning checklist. Compliance feedback was provided in the form of reports and reeducation. Outcomes were reported as checklist compliance. The use of remote video auditing to document manual processing is a feasible approach and feedback and reeducation increased manual-cleaning compliance from 53.1% (95% confidence interval, 34.7-71.6) to 98.9% (95.0% confidence interval, 98.1-99.6). PMID- 29195780 TI - Waterborne Pseudomonas aeruginosa transmission in a hematology unit? AB - BACKGROUND: Pseudomonas aeruginosa is an important nosocomial pathogen that commonly colonizes hospital water supplies, including in taps and sinks. We report the transmission of P. aeruginosa from water to patients in a clinical hematology setting. METHODS: P. aeruginosa from water samples were compared to clinical isolates from hematology ward patients, via molecular typing (pulsed field gel electrophoresis). RESULTS: P. aeruginosa cultured from blood cultures from 3 patients was indistinguishable from water strains, by molecular typing. Based on infection control inspections, the transmission event was surmised to be due to cleaning of equipment, specifically an infusion therapy procedure tray used to transport intravenous drugs to patients, with water from an outlet colonized by P. aeruginosa. CONCLUSION: We show the importance of holistic factors, such as disposal of patient waste water, cleaning of tap outlets, and cleaning of medical equipment, in the transmission of P. aeruginosa, and demonstrate that the role of waterborne transmission of this organism in a hematology setting cannot be overlooked. We suggest that appropriate management of water, including both holistic and engineering interventions, is needed to stop transmission of P. aeruginosa from water to patients. PMID- 29195781 TI - Effect of hand hygiene on infectious diseases in the office workplace: A systematic review. AB - BACKGROUND: Extensive data suggests that hand hygiene is a critical intervention for reducing infectious disease transmission in the clinical setting. However, it is unclear whether hand hygiene is effective at cutting down on infectious illnesses in non-clinical workplaces. The aim of this review is to assess the current literature concerning the effects of hand-washing interventions on infectious disease prevention among employees in nonclinical, office-based workplaces. METHODS: In compiling this review, PubMed, Scopus, and Business Source Premier were examined for studies published from 1960 through 2016. RESULTS: Eleven studies (eight experimental, two observational, one a simulation) were identified as eligible for inclusion. Hand-hygiene interventions at various levels of rigor were shown to reduce self-reported illness symptoms. CONCLUSIONS: Hand hygiene is thought to be more effective against gastrointestinal illness than it is against respiratory illness, but no clear consensus has been reached on this point. Minimal hand-hygiene interventions seem to be effective at reducing the incidence of employee illness. Along with reducing infections among employees, hand-hygiene programs in the workplace may provide additional benefits to employers by reducing the number of employee health insurance claims and improving employee morale. Future research should use objective measures of hand hygiene and illness, and explore economic impacts on employers more fully. PMID- 29195782 TI - HMGB1 mediates depressive behavior induced by chronic stress through activating the kynurenine pathway. AB - Our previous study has reported that the proactive secretion and role of central high mobility group box 1 (HMGB1) in lipopolysaccharide-induced depressive behavior. Here, the potential mechanism of HMGB1 mediating chronic-stress-induced depression through the kynurenine pathway (KP) was further explored both in vivo and in vitro. Depression model was established with the 4-week chronic unpredictable mild stress (CUMS). Sucrose preference and Barnes maze test were performed to reflect depressive behaviors. The ratio of kynurenine (KYN)/tryptophan (Trp) represented the enzyme activity of indoleamine-2,3 dioxygenase (IDO). Gene transcription and protein expression were assayed by real time RT-PCR and western-blot or ELISA kit respectively. Along with depressive behaviors, HMGB1 concentrations in the hippocampus and serum substantially increased post 4-week CUMS exposure. Concurrent with the upregulated HMGB1 protein, the regulator of translocation of HMGB1, sirtuin 1 (SIRT1) concentration in the hippocampus remarkably increased. In addition to HMGB1 and SIRT1, IDO, the rate limiting enzyme of KP, was upregulated at the level of mRNA expression and enzyme activity in stressed hippocampi and LPS/HMGB1-treated hippocampal slices. The gene transcription of kynurenine monooxygenase (KMO) and kynureninase (KYNU) in the downstream of KP also increased both in vivo and in vitro. Mice treated with ethyl pyruvate (EP), the inhibitor of HMGB1 releasing, were observed with lower tendency of developing depressive behaviors and reduced activation of enzymes in KP. All of these experiments demonstrate that the role of HMGB1 on the induction of depressive behavior is mediated by KP activation. PMID- 29195783 TI - Platelet glycoprotein receptor Ib blockade ameliorates experimental cerebral ischemia-reperfusion injury by strengthening the blood-brain barrier function and anti-thrombo-inflammatory property. AB - Blood-brain barrier (BBB) disruption, thrombus formation and immune-mediated inflammation are important steps in the pathophysiology of cerebral ischemia reperfusion injury but are still inaccessible to therapeutic interventions. Recent studies have provided increasing evidence that blocking of platelet glycoprotein (GP) receptor Ib might represent a novel target in treating acute ischemic stroke. This research was conducted to explore the therapeutic efficacy and potential mechanisms of GPIbalpha inhibitor (anfibatide) in a model of brain ischemia-reperfusion injury in mice. Male mice underwent 90 min of right middle cerebral artery occlusion (MCAO) followed by 24 h of reperfusion. Anfibatide (1, 2, 4 ug/kg) or tirofiban were administered intravenously 1 h after reperfusion. The results showed that anfibatide could significantly reduce infarct volumes, increase the number of intact neuronal cells and improve neurobehavioral function. Moreover, anfibatide could reduce post ischemic BBB damage by attenuating increased paracellular permeability in the ischemia hemisphere significantly. Stroke-induced increases in activity and protein expression of macrophage-1 antigen (MAC-1) and P-selectin were also reduced by anfibatide intervention. Finally, anfibatide exerted antithrombotic effects upon stroke by decreased the number of microthrombi formation. This is the first demonstration of anfibatide's efficacy in protecting the BBB integrity and decreasing neutrophil inflammation response mediated by MAC-1 besides microthrombus formation inhibition in the brain during reperfusion. Anfibatide, as a promising anti-thrombo-inflammation agent, could be beneficial for the treatment of ischemic stroke. PMID- 29195784 TI - A novel in silico minigene vaccine based on CD4+ T-helper and B-cell epitopes of EG95 isolates for vaccination against cystic echinococcosis. AB - EG95 oncospheral antigen plays a crucial role in Echinococcus granulosus pathogenicity. Considering the diversity of antigen among different EG95 isolates, it seems to be an ideal antigen for designing a universal multivalent minigene vaccine, so-called multi-epitope vaccine. This is the first in silico study to design a construct for the development of global EG95-based hydatid vaccine against E. granulosus in intermediate hosts. After antigen sequence selection, the three-dimensional structure of EG95 was modeled and multilaterally validated. The preliminary parameters for B-cell epitope prediction were implemented such as the possible transmembrane helix, signal peptide, post translational modifications and allergenicity. The high ranked linear and conformational B-cell epitopes derived from several online web-servers (e.g., ElliPro, BepiPred v1.0, BcePred, ABCpred, SVMTrip, IEDB algorithms, SEPPA v2.0 and Discotope v2.0) were utilized for multiple sequence alignment and then for engineering the vaccine construct. T-helper based epitopes were predicted by molecular docking between the high frequent ovar class II allele (Ovar-DRB1*1202) and hexadecamer fragments of the EG95 protein. Having used the immune-informatics tools, we formulated the first EG95-based minigene vaccine based on T-helper epitope with high-binding affinity to the ovar MHC allele. This designed construct was analyzed for different physicochemical properties. It was also codon-optimized for high-level expression in Escherichia coli k12. Taken all, we propose the present in silico vaccine constructs as a promising platform for the generation of broadly protective vaccines for species and genus-specific immunization of the natural hosts of the parasite. PMID- 29195785 TI - Chest High-resolution Computed Tomography Findings in 601 Patients with Inflammatory Bowel Diseases. AB - RATIONALE AND OBJECTIVES: Pulmonary involvement in inflammatory bowel disease may reflect the common embryonic origin of the gastrointestinal tract and the bronchial tree. No studies have compared pulmonary high-resolution computed tomography (HRCT) findings between ulcerative colitis (UC) and Crohn disease (CD). This study aimed to assess the relationship between pulmonary HRCT findings and inflammatory bowel disease activity and to compare HRCT findings between UC and CD. MATERIALS AND METHODS: We retrospectively identified 601 consecutive patients (350 with UC and 251 with CD) who had undergone chest HRCT examinations at our institutions between April 2004 and April 2016. Parenchymal abnormalities, enlarged lymph nodes, and pleural effusion were evaluated on HRCT. RESULTS: One hundred sixty-seven patients (94 men, 73 women; aged 12-86 years, mean: 47.2 years) with UC and 93 patients (61 men, 32 women; aged 12-71 years, mean: 37.9 years) with CD had abnormal findings on chest HRCT. The HRCT findings of UC and CD mainly consisted of centrilobular nodules (in 49.1% and 45.2% of cases, respectively) and bronchial wall thickening (in 31.7% and 54.8%, respectively). There was no relationship between HRCT findings and disease activity. Bronchial wall thickening was significantly more frequent in patients with CD than in those with UC (P < .001). CONCLUSION: The main chest HRCT findings in UC and CD are centrilobular nodules and bronchial wall thickening. There are differences in HRCT findings between UC and CD. PMID- 29195786 TI - Normal Axillary Lymph Node Variability Between White and Black Women on Breast MRI. AB - RATIONALE AND OBJECTIVES: This study aimed to determine if there were differences in the imaging features of normal lymph nodes between white and black women using magnetic resonance imaging. MATERIALS AND METHODS: Following institutional review board approval, we identified white and black women who underwent breast magnetic resonance imaging from November 1, 2008 to December 31, 2013 at our institution. To identify normal lymph nodes for measurement, patients with any benign or malignant causes for lymph node enlargement and patients with any subsequent breast cancer in the following 2 years were excluded. Black and white women were age matched at a 1:2 ratio. The largest lymph node in each axilla was measured for the long-axis length and maximal cortical thickness. Comparisons were made between white and black women using a conditional logistic regression to control for matching. RESULTS: There were 55 black women and 110 white women for analysis. The mean lymph node long-axis length was 14.7 +/- 5.3 mm for black women and 14.4 +/- 6.4 mm for white women (P = .678). The mean maximum cortical thickness was 3.3 +/- 1.6 mm for black women and 2.6 +/- 1.4 mm for Caucasian women (P < .001). A significantly higher percentage of black than white women had cortical thicknesses greater than threshold values of 3, 4, 5, 6, and 7 mm (P < .01 for all). CONCLUSIONS: The normal lymph node cortical thickness in black women is significantly greater than in white women, which should be considered when deciding to recommend a lymph node biopsy. PMID- 29195787 TI - High-risk Plaque and Calcification Detected by Coronary CT Angiography to Predict Future Cardiovascular Events After Percutaneous Coronary Intervention. AB - RATIONALE AND OBJECTIVES: The purpose of this study was to investigate whether high-risk plaque (HRP) and calcium assessed by coronary computed tomography (CT) could predict future cardiovascular events after second-generation drug-eluting stent (DES) placement. MATERIALS AND METHODS: We analyzed 317 patients from December 2012 to April 2015 who underwent coronary CT followed by DES placement. HRP was defined as a plaque with positive remodeling and low attenuation or a plaque with a napkin-ring sign. Coronary calcium was assessed by Agatston score (AS). Patients were divided into three groups: low risk, HRP negative and AS <400; intermediate risk, HRP positive and AS >=400; high risk, HRP positive and AS >=400. The primary end point was a composite of all-cause mortality, myocardial infarction, fatal arrhythmia, or repeated revascularization. Kaplan Meier analysis was used to estimate the distribution of time to events. RESULTS: A total of 74 events (23%) occurred during a median follow-up of 25.8 months. Patients with primary end points had HRP more frequently (70% vs 51%, P = 0.003) and were more calcified (AS, 471 [interquartile range, 143-1614] vs 289 [interquartile range, 63-787]; P = 0.01) than patients without primary end points. The frequency of primary end point increased significantly in the intermediate- and high-risk patients (P = 0.0011). Multivariate analysis showed that the hazard ratio of the intermediate- and high-risk groups was 1.91 (95% confidence interval, 1.04-3.77; P = 0.037) and 2.66 (95% confidence interval, 1.27-5.73; P = 0.009), respectively. CONCLUSION: Plaque and calcification analysis by coronary CT could predict future cardiovascular events after second generation DES placement. PMID- 29195788 TI - Transcatheter aortic valve replacement: Suitable for all? PMID- 29195789 TI - Responses of PKCepsilon to cardiac overloads on myocardial sympathetic innervation and NET expression. AB - Protein kinase C (PKC) is a key mediator of many diverse physiological and pathological responses. PKC activation play an important regulatory role of cardiac function. The present study was performed to investigate whether there were differential activations of the PKCepsilon and how the activation coupled with norepinephrine transporter (NET) surface expression, sympathetic innervation pattern and extracellular matrix remodeling in different cardiac hemodynamic overloads induced by abdominal aortic constriction or aortocaval fistula. At 8weeks after the operations, heart failure were induced, accompanied with myocardial hypertrophy, which was more pronounced in pressure overload (POL) than that of volume overload (VOL) rats, left ventricular dysfunction and increased plasma norepinephrine (NE). In POL rats there was an increase in myocardial collagen deposition, in contrast, the amount decreased in VOL as compared with the sham rats. POL remarkably upregulated PKCepsilon membrane-cytosol ratio and downregulated NET membrane fraction, whereas, in VOL induced opposite changes. Accompanied with the PKCepsilon activation, nerve sprouting, evidenced by myocardial GAP43 protein increased, and different nerve phenotypes were found, in POL tyrosine hydroxylase (TH) positive nerve density increased with NET and choline acetyltransferase (ChAT) immunoreactivity density decreased, in contrast, in VOL NET and ChAT increased, TH did not change. The overloads did not induce alteration of NET mRNA expression, but resulted in different myocardial beta1-AR mRNA expression, in POL beta1-AR mRNAwas significantly downregulated, while in VOL rats unaltered. Conclusion, the present results suggested that the different cardiac hemodynamic overload could differentially activate a common signaling, PKCepsilon intermediate and thereby generate biological diversity.

AB - The present study reports the effect of indanone derivatives on scopolamine induced deficit cholinergic neurotransmission serving as promising leads for the therapeutics of cognitive dysfunction. Eleven compounds 54-64 have been designed, synthesised and evaluated against behavioural alterations using step down passive avoidance protocol at a dose of 0.5 mg/kg with Donepezil (1) as the reference standard. All the synthesised compounds were evaluated for their in vitro acetylcholinesterase (AChE) inhibition at five different concentrations using mice brain homogenate as the source of the enzyme. Compounds 54, 56, 59 and 64 displayed appreciable activity with an IC50 value of 14.06 uM, 12.30 uM, 14.06 uM and 12.01 uM, respectively towards acetylcholinesterase inhibition. The molecular docking study performed to predict the binding mode of the compounds suggested that these compounds could bind appreciably to the amino acids present at the active site of recombinant human acetylcholinesterase (rhAChE). The behavioural, biochemical and in silico pharmacokinetic studies were in concordance with each other. PMID- 29195795 TI - 7-Methylguanosine monophosphate analogues with 5'-(1,2,3-triazoyl) moiety: Synthesis and evaluation as the inhibitors of cNIIIB nucleotidase. AB - The hydrolysis of nucleoside 5'-monophosphates to the corresponding nucleosides and inorganic phosphate is catalysed by 5'-nucleotidases, thereby contributing to the control of endogenous nucleotide turnover and affecting the fate of exogenously delivered nucleotide- and nucleoside-derived therapeutics in cells. A recently identified nucleotidase cNIIIB shows preference towards 7 methylguanosine monophosphate (m7GMP) as a substrate, which suggests its potential involvement in mRNA degradation. However, the extent of biological functions and the significance of cNIIIB remains to be elucidated. Here, we synthesised a series of m7GMP analogues carrying a 1,2,3-triazole moiety at the 5' position as the potential inhibitors of human cNIIIB. The compounds were synthesised by using the copper-catalysed azide-alkyne cycloaddition (CuAAC) between 5'-azido-5'-deoxy-7-methylguanosine and different phosphate or phosphonate derivatives carrying terminal alkyne. The analogues were evaluated as cNIIIB inhibitors using HPLC and malachite green assays, demonstrating that compound 1a, carrying a 1,2,3-triazoylphosphonate moiety, inhibits cNIIIB activity at micromolar concentrations (IC50 87.8 +/- 7.5 uM), while other analogues showed no activity. In addition, compound 1d was identified as an artifical substrate for HscNIIIB. Further characterization of inhibitor 1a revealed that it is poorly recognised by other m7G-binding proteins, eIF4E and DcpS, indicating its selectivity towards cNIIIB. The first inhibitor (1a) and unnatural substrate (1d) of cNIIIB, identified here, can be used as molecular probes for the elucidation of biological roles of cNIIIB, including the verification of its proposed function in mRNA metabolism. PMID- 29195796 TI - A low gradient junction technique of craniospinal irradiation using volumetric modulated arc therapy and its advantages over the conventional therapy. AB - A technique using volumetric-modulated arc therapy (VMAT) fields for craniospinal irradiation with low dose gradients at the field junction was tested for its sensitivity to positional inaccuracy. It was compared against the conventional three-dimensional (3D) conformal radiotherapy in terms of dose uniformity at the junction. Treatment plans generated for ten patients who received craniospinal irradiation (35Gy in 21 fractions) by VMAT technique at our centre were included in this study. For these patients, 3D conformal radiotherapy plans were also generated in addition to the VMAT treatment plans. Intentional shifting of the cranial field in the superior and then in the inferior directions was done, creating a gap or overlap between the fields. Consequent changes in dose distributions in these two plans to positional inaccuracies were studied. The 3D conformal radiotherapy plans showed large dose variations at the junction due to positional shifts as compared to the VMAT plans. With a 5mm superior shift of the cranial field isocentre creating a gap between the cranial and spinal fields, the magnitudes of under-dosing were 13.9+/-3.6Gy and 4.8+/-2.0Gy for 3D conformal radiotherapy and VMAT respectively. When the cranial field was moved by 5mm inferiorly creating an overlap between the fields, overdose to the effects of 10.3+/-4.0Gy and 4.9+/-1.3Gy were observed for the 3D conformal radiotherapy plans and VMAT plans respectively. The VMAT technique is insensitive to longitudinal setup errors (1-3mm) in patients because of the existence of low dose gradients at the junction between fields. This is unlike the 3D conformal radiotherapy plans which have steep dose gradients at the field edges and thus are highly sensitive to setup errors. Such an advantage for VMAT circumvents the need for dose feathering often practiced with the 3D conformal radiotherapy technique and makes the technique simpler to follow. PMID- 29195797 TI - Laparoscopic Ureteroneocystostomy with a Vesicopsoas Hitch in 10 Steps. AB - STUDY OBJECTIVE: Laparoscopic ureteroneocystostomy with a vesicopsoas hitch has the advantages of a minimally invasive approach. The standardization and description of the technique are the main objectives of this video. We described this procedure in 10 steps, which could help to understand and perform this procedure. METHODS: This video presents an approach to laparoscopic ureteroneocystostomy with a vesicopsoas hitch, which was clearly divided into 10 steps. The local institutional review board was consulted and ruled that approval was not required for this video article because the video describes a technique and does not report a clinical case. The patient cannot be identified, and she gave informed consent. RESULTS: The 10 steps are as follows: step 1, identification of the healthy ureter; step 2, identification of the stenotic part; step 3, section of the ureter; step 4, bladder mobilization; step 5, anterior cystostomy; step 6, psoas hitch; step 7, closure of the anterior cystostomy; step 8, posterior spatulation of the ureter; step 9, cystostomy of the superolateral bladder dome; and step 10, ureteral suture to the bladder. CONCLUSION: Laparoscopic ureteroneocystostomy with a vesicopsoas hitch is an effective technique for intrinsic ureteral endometriosis; it usually needs ureteral resection with end-to-end reanastomosis or reimplantation if the anastomosis is in tension. The 10 steps help to perform each part of surgery in logical sequence, making the procedure faster to adopt and learn. The standardization of laparoscopic techniques could help to reduce the learning curve. PMID- 29195798 TI - Transarterial Embolization of a Bartholin Cyst before Resection.

AB - Carboxylated cellulose nanocrystal-sodium alginate (CCN-Alg) hydrogel beads were easily prepared through a cross-linking method. The structure and properties of the composite beads were characterized by TEM, FTIR, SEM, XPS, thermogravimetric analysis (TGA), and zeta potential measurement. A high ratio of 76% of the Pb(II) ion was adsorbed within the first 2h, and the adsorption equilibrium was nearly reached after 3h. The experimental isotherm could be fitted by the Langmuir model, yielding an extreme adsorption capacity of 338.98mgg-1. The adsorption process followed a pseudo-second-order kinetic model, and thermodynamic analyses confirmed that the adsorption is a spontaneous and endothermic process. Regeneration tests with acid treatment indicated that the CCN-Alg beads performed well in repeated Pb(II) adsorptions, as they could maintain an adsorption capacity of 223.2mgg-1 after five repeated cycles. These results indicate that these CCN-Alg beads are a potentially effective and sustainable adsorbent for application in wastewater treatment. PMID- 29195800 TI - NIR triggered liposome gold nanoparticles entrapping curcumin as in situ adjuvant for photothermal treatment of skin cancer. AB - We report the synthesis of a biodegradable liposome gold nanoparticles for curcumin (Au-Lipos Cur NPs) delivery. This entrapped curcumin served as an in situ adjuvant for photothermal therapy. Curcumin was loaded in Au-Lipos NPs with an encapsulation efficiency of ~70%. The gold coating enabled the NPs to specifically absorb NIR light (780nm) by virtue of Surface Plasmon Resonance (SPR) and this light energy was converted to heat. The generated heat destabilized the liposomal core enhancing the release of encapsulated curcumin. Photothermal transduction efficacy of Au-Lipos NPs (loaded with curcumin) showed a significant temperature rise upon laser irradiation causing irreversible cellular damage. In vitro photothermal effect and intracellular uptake was evaluated in B16 F10 (melanoma) cell line. Au-Lipos Cur NPs showed significantly enhanced uptake when compared with free curcumin.

AB - A series of twelve furanochalcones (F1-F12) was synthesized and investigated for their human monoamine oxidase inhibitory activities. Among the series, compound (2E, 4E)-1-(furan-2-yl)-5-phenylpenta-2, 4-dien-1-one (F1), which was analyzed by single-crystal X-ray diffraction, showed potent and selective MAO-B inhibitory activity with an inhibition constant (Ki) value of 0.0041 MUM and selectivity index of (SI) 172.4, and exhibited competitive inhibition. Introduction of a cinnamyl group to the furanochalcone significantly increased the inhibitory activity. In the dilution-recovery experiments, the residual activities of MAO-A and MAO-B by F1 under the diluted condition fully recovered as compared with the undiluted condition, indicating F1 is a reversible inhibitor. The Ki value of F1 is the lowest among the values of chalcone derivatives and furthermore lower than that (0.0079 MUM) of the reversible MAO-B inhibitor, lazabemide, a marketed drug. Molecular docking study against hMAO-B provided the binding site interactions of the lead compound, including strong pi-pi stacking between the phenyl system and FAD nucleus.

AB - INTRODUCTION: Schizophrenia is a disorder affecting 1% of the population and is associated with severe functional impairment. Negative symptoms are responsible for the majority of this impairment, and many patients with schizophrenia have negative symptoms. However, their evaluation is still a challenge. Thus, standardized assessments are needed to facilitate identification of these symptoms. Many tools have been developed, but most are based on observer ratings. Self-evaluation can provide an additional outcome measure and allow patients to be more engaged in their treatment. The Self-evaluation of Negative Symptoms (SNS) has been developed recently. This is a remarkably understandable instrument for patients with schizophrenia as it allows them to readily complete it without assistance, providing information with respect to their own perception of negative symptoms. The SNS is a self-assessment that permits patients to evaluate themselves in 5 dimensions of negative symptoms. This validation study for the SNS revealed good psychometric properties alongside satisfactory acceptance by patients. AIM: This study was to confirm the validation of the French version of the self-evaluation of negative symptoms (SNS). METHODS: Patients with schizophrenia or schizoaffective disorder according to the DSM-IV-R, with a stable regimen of anti-psychotic drugs for the last two months, aged more than 18 years old were eligible for the study. Symptoms were rated using the SNS, the Scale for the Assessment of Negative Symptoms (SANS), the Calgary Depression Scale for Schizophrenics (CDSS), the Brief Psychiatric Rating Scale (BPRS) and the Clinical Global Impression and Parkinsonism. Patients were asked to fulfill the SNS twice, 6 weeks apart. RESULTS: Sixty patients were evaluated. Cronbach's coefficient (alpha=0.8) showed good internal consistency. The SNS significantly correlated with the SANS (r=0.6), the negative sub-score of the BPRS (r=0.6) and the Clinician Global Impression on the severity of negative symptoms (r=0.7). SNS scores did not correlate with level of insight (r=0.08) or Brief Psychiatric Rating Scale positive sub-scores (r=0.2). SNS scores correlated with CDSS scores. However, we did not find correlation between the first item of the CDSS which evaluates depression and the "diminished emotional range" sub-score of SNS. The test-retest of SNS revealed no changes of scores at two evaluations 6 weeks apart. CONCLUSION: The acceptance by patients of the SNS was excellent. The French version of the SNS demonstrated a good internal consistency, good convergent validity and good discriminant validity. The study demonstrates the ability of patients with schizophrenia to accurately report their own experiences. Self-assessments of negative symptoms should be more widely employed in clinical practice because they may allow patients with schizophrenia to develop appropriate coping strategies.

Recent publications suggest a particular interest of psychostimulants in the treatment of depression in the elderly. The aim of this article is to review the literature on the role of psychostimulants in the treatment of depression in older adults. METHODS: The literature review focused on efficacy and tolerability studies of psychostimulants in the treatment of depression for the elderly that were published between 1980 and 2016. The only inclusion criterion applied was an average age of the sample studied greater than or equal to 60 years. RESULTS: Overall, 12 trials were selected: 3 controlled trials and 9 uncontrolled trials. Of the 3 controlled trials, one compared parallel groups and the other two were cross-tests. Among the psychostimulants, methylphenidate was the most studied molecule. The trials demonstrate an efficacy of this molecule in particular as an add-on therapy in old-age depression but for the most part with a level of proof that remains insufficient. CONCLUSIONS: The small size of the samples and the methodological limitations of the studies obviate the possibility of extracting definitive conclusions concerning the place of psychostimulants in the treatment of depression in the elderly. Further studies are required in particular in the treatment of resistant depressive episodes. PMID- 29195805 TI - [Symptomatic remission and its relationship to social functioning in Tunisian out patients with schizophrenia]. AB - INTRODUCTION: The concept of symptomatic and functional remission represents an important challenge in the care of the mentally ill, particularly in patients with schizophrenia. Operational criteria for symptomatic remission in schizophrenia have been proposed by Andreasen et al. (2005). Over the last decade, these criteria have been widely validated; however few studies have been conducted outside developed countries. Moreover, the association of symptomatic remission with functional outcome has not yet been established in developing countries including Tunisia, as there may be variability in the social and familial environment. OBJECTIVES: To determine the frequency and associated factors of symptomatic remission in a sample of Tunisian out-patients with schizophrenia and to explore the relationship between symptomatic remission and some indicators of social functioning. METHODS: A cross-sectional study was carried-out on 115 out-patients with schizophrenia (87 males, 28 females, mean age=37.56+/-10.2 years) in the psychiatry department of the university hospital in Monastir (Tunisia). Nearly all of the patients (98.26%) had been hospitalized at least once in a psychiatric unit. The last hospitalization dated back to 39 months on average (range=6 months to 16 years). Symptomatic remission was assessed by the eight core items of the positive and negative syndrome scale (PANSS). These are the items P1 "Delusions"; P3 "Hallucinatory behavior" and G9 "Unusual thought content" for the positive dimension, the items P2 "Conceptual disorganization" and G5 "Mannerism and disorders of posture" for the disorganization dimension and the items N1 "Blunted affect", N4 "Social withdrawal" and N6 "Lack of spontaneity and flow of conversation" for the negative dimension. A score of mild or less on all eight-core symptoms constitutes symptomatic remission. This symptom level should have been maintained for six months. The social functioning was assessed by the Social and Occupational Functioning Assessment Scale (SOFAS) and the Social Autonomy Scale (SAS) exploring personal care, management of daily life, resource management, the relationship with the outside and the emotional life and relationships social. A multivariate analysis using a binary logistic regression was conducted with as a dependent variable "symptomatic remission" and as explanatory variables the associated variables with symptomatic remission in bivariate analysis with age and gender. RESULTS: The symptomatic remission was observed in 50.4% of patients. The items corresponding to positive dimension (P1, P3 and G9) and the item P2 "conceptual disorganization" had a better predictive value of symptomatic remission. After multivariate analysis, the associated factors of symptomatic remission were the acute of onset (P=0.026), the low score of negative symptoms during the last hospitalization (P=0.017) and the episodic course (P<0.0001). However, age or gender of the patients, educational or socioeconomic level, psychiatric family history, age of onset, duration of untreated psychosis, number and duration of previous hospitalizations, antipsychotic treatment dosage were not associated with symptomatic remission in our sample. The mean score of the SOFAS was 48.47+/-14.44, and the mean score of the SAS was 56.6+/-16.84. A significant association was shown between the SOFAS score and the symptomatic remission (P<0.0001) and between the SAS score and the symptomatic remission (P<0.0001). Moreover, a significant association was found between symptomatic remission and occupational activity (P=0.03). CONCLUSION: The frequency of symptomatic remission according the PANSS criteria in our sample is above the average of the reported rates in literature (30 to 60%). This can be explained by the frequency of symptomatic remission in outpatient versus inpatients, or in relation to the notion of a more favorable course of schizophrenia in developing countries, although this notion is controversial. Remitter patients had significantly an acute onset of disorders, a low score of negative symptoms during the last hospitalization and an episodic course. They also showed a significant trend for better social functioning. In fact, a significant association was shown in our sample between symptomatic remission and social functioning. These results suggest that the concept of remission has important implications for the treatment of patients with schizophrenia.

The aim of our study was to describe the epidemiological and clinical characteristics of young suicide attempters among a clinical population and to assess their potential evolution over a period of11 years. METHODS: We conducted a descriptive retrospective study among a clinical population of suicide attempters referred to the child psychiatric department of the Razi hospital, the inpatient reference department in the north and center of Tunisia, between January 2005 and December 2015. Based on the WHO definition we considered as suicide attempts, "any deliberate act, without any fatal outcome, aimed at performing a gesture of violence on one's own person or to ingest a toxic substance or drugs at a dose higher than the dose recognized as therapeutic". We conducted collection of data from patient records based on a pre-established record with the following parameters: clinical study of patients including: socio demographic data, clinical characteristics based on DSM 4 criteria and environmental factors including family history of psychiatric disorder, abuse, school difficulties and failure. RESULTS: The sample was composed of 159 patients having a mean age of 12.8 years with extremes from 5.8 to 17 years. It was composed of 74.2% girls and 25.8% boys. Medical intoxication was the most common mean (68.6%) followed by physical means (20.1%) and toxic products ingestion (12.6%). The suicide attempts were mainly non-premeditated (83.1%). Our patients reported a previous suicide attempt in 25.8% of cases. Chronic somatic disorders were found among 24.5% of our sample. Psychiatric disorders among children, parents, abuse, and school failure were found in respectively 48.4%, 50.6%, 37.1% and 13.4% of suicidal patients. Psychiatric disorders were dominated by depressive disorders and oppositional defiant disorders associated with conduct disorder. The chronological study highlighted significant modifications starting from 2013/2014, reflecting a recent trend: a significant decrease in suicidal age was found since the year 2015: children under 10 years of age, who constituted 8.4 % (n=10) of suicides during the period from (n=119), accounted for 20 % (n=32) of the patients enumerated in the year 2015 (P=0.045). We also found that the percentage of suicidal attempts committed in winter was higher from 2013 than in previous years (P=0.019). We also noted a significant increase in 2014 in the proportion of patients with a personal history of suicidal attempt when compared to previous years (P=0.045). The use of physical means became more frequent from 2013 (P=0.019). This is confirmed by comparing the suicide attempts prior to and from 2014 (P=0.007) or by comparing the suiced attempts committed in 2015 to the ones committed during the previous ten years (P=0.007). Finally, there was a statistically significant distribution of serious organic effects (coma) as a function of years: such complications were more frequent in the course of suicidal attempts committed after 2013 (P=0.009). CONCLUSIONS: Since 2013/2014 we found a recent trend characterized by more children among suicidals, more patients reporting a previous suicide attempt, more frequent use of physical means and a greater proportion of suicide attempts realized in winter. This raises the challenge for more research on the topic as well as new therapeutic interventions. PMID- 29195807 TI - Parallel Evaluation of Circulating Tumor DNA and Circulating Tumor Cells in Metastatic Colorectal Cancer. AB - BACKGROUND: Tissue biopsy is the gold standard for tumor genotyping, but it is an invasive procedure providing a single snapshot into tumor heterogeneity. Liquid biopsy approaches, encompassing the analysis of circulating tumor DNA (ctDNA) or circulating tumor cells (CTCs), have been proposed as an alternative, with the potential of providing a comprehensive portrait of the tumor molecular landscape. In metastatic colorectal cancer (mCRC), both CTCs and ctDNA analysis have been investigated, but comparative analyses are limited. METHODS: We collected blood samples from 20 consecutive patients with mCRC with at least 1 of the following inclusion criteria: high tumor burden (> 1 metastasis), intact colonic primary tumor, disease progression at the time of sampling, <= 2 cycles of cytotoxic chemotherapy of current treatment course, and time between last chemotherapy cycle >= 4 weeks. RESULTS: Nineteen of 20 samples displayed the appropriate quality for CTC analysis. CTCs could be isolated in 7 (36.8%) of 19 evaluable patients. The median number of CTCs was 0 (range, 0-73). In 2 patients, we isolated > 1 CTC, and in five, we found 1 CTC. We retrieved ctDNA in all samples, with a median amount of 732,573 GE/mL (range, 174,774-174,078,615 GE/mL). Concordance between ctDNA and tissue for RAS, BRAF, and ERBB2 alterations was found in 11 (84.6%) of 13 cases. CONCLUSIONS: In this cohort, we show that ctDNA was detectable in all cases, whereas CTCs were detectable in one-third of the cases. ctDNA analysis was achieved with a smaller amount of blood sampling and allowed molecular characterization. Our data indicate that ctDNA is a readily available candidate for clinical application in mCRC. PMID- 29195808 TI - Excellent prognosis of patients with intermediate-risk neuroblastoma and residual tumor postchemotherapy. AB - BACKGROUND/PURPOSE: The prognosis of patients with intermediate-risk neuroblastoma is favorable; therefore, a reduction therapy is desired. However, the long-term prognosis of those with residual tumor is unclear. The aim of this study was to clarify the necessity of residual tumor resection. METHODS: We retrospectively reviewed the records of patients diagnosed with intermediate-risk neuroblastoma who either were treated by chemotherapy only (nonresection group; n=16), or received postchemotherapy tumor resection (resection group; n=9). RESULTS: In the nonresection group, tumor size decreased in 14 patients; 5 had no detectable local tumor at the end of the follow-up period. Tumor size increased in 2 patients 1.5-2.5years postchemotherapy. Both patients received additional treatment and survived. All patients survived during the median follow-up time of 127months. In the resection group, 5 patients received complete resections and 4 patients received nearly complete resections. All patients survived during the median follow-up time of 84months. In 8 out of 9 resected tumors, regression or maturation was pathologically induced by chemotherapy-only treatment. CONCLUSION: Patients with intermediate-risk neuroblastoma with or without postchemotherapy residual tumor resection had an excellent long-term outcome. The tumor pathology with intermediate-risk neuroblastoma might be susceptible to change to regression or maturation by chemotherapy. LEVEL OF EVIDENCE: IV. PMID- 29195809 TI - Reduced psychological distress in familial chylomicronemia syndrome after patient support group intervention. AB - Familial chylomicronemia syndrome (FCS) is a rare genetic disorder that is associated with severe hypertriglyceridemia and complications that often include recurrent pancreatitis beginning in childhood. Patients with FCS frequently struggle to maintain normality in their lives as a consequence of the necessity to severely restrict their intake of dietary fat coupled with the constant threat of recurrent pancreatitis. Patients typically face a high level of psychological stress and anxiety in association with reduced measures of quality of life. Routine medical care for affected patients usually does not adequately address the day-to-day struggles that accompany a diagnosis of FCS, resulting in ongoing suffering for many patients. We describe herein the highly beneficial effects of a support group interaction for a patient with FCS. PMID- 29195811 TI - The Pore-Forming Protein Gasdermin D Regulates Interleukin-1 Secretion from Living Macrophages. AB - The interleukin-1 (IL-1) family cytokines are cytosolic proteins that exhibit inflammatory activity upon release into the extracellular space. These factors are released following various cell death processes, with pyroptosis being a common mechanism. Recently, it was recognized that phagocytes can achieve a state of hyperactivation, which is defined by their ability to secrete IL-1 while retaining viability, yet it is unclear how IL-1 can be secreted from living cells. Herein, we report that the pyroptosis regulator gasdermin D (GSDMD) was necessary for IL-1beta secretion from living macrophages that have been exposed to inflammasome activators, such as bacteria and their products or host-derived oxidized lipids. Cell- and liposome-based assays demonstrated that GSDMD pores were required for IL-1beta transport across an intact lipid bilayer. These findings identify a non-pyroptotic function for GSDMD, and raise the possibility that GSDMD pores represent conduits for the secretion of cytosolic cytokines under conditions of cell hyperactivation. PMID- 29195812 TI - Effects of a single condylar neck fracture without condylar cartilage injury on traumatic heterotopic ossification around the temporomandibular joint in mice. AB - OBJECTIVES: In this study, we tried to explore the effects of a single condylar neck fracture without condylar cartilage injury during the pathogenesis process of traumatic heterotopic ossification around the temporomandibular joint (THO TMJ). STUDY DESIGN: One-month-old C57 BL/6 J male mice were divided into 2 groups. In group 1, condylar cartilage was partially removed in the right joint to induce THO. In group 2, a single fracture on the condylar neck was created using small scissors. The condylar head was repositioned to its original place if any displacement occurred. The phenotypes were observed using gross observation, micro-computed tomography, and histologic examination. RESULTS: The results showed obvious hyperplasia in the right condyle in group 1, with ectopic bones and cartilage in the periarticular region. In group 2, the surface of condyle was smooth, but the size of the right condylar head became smaller. CONCLUSIONS: Taking these findings together, we concluded that it is condylar cartilage injury, and not a single condylar neck fracture without condylar cartilage injury, that contributes to the development of THO-TMJ.

PMID- 29195810 TI - Natural Parasite Exposure Induces Protective Human Anti-Malarial Antibodies. AB - Antibodies against the NANP repeat of circumsporozoite protein (CSP), the major surface antigen of Plasmodium falciparum (Pf) sporozoites, can protect from malaria in animal models but protective humoral immunity is difficult to induce in humans. Here we cloned and characterized rare affinity-matured human NANP reactive memory B cell antibodies elicited by natural Pf exposure that potently inhibited parasite transmission and development in vivo. We unveiled the molecular details of antibody binding to two distinct protective epitopes within the NANP repeat. NANP repeat recognition was largely mediated by germline encoded and immunoglobulin (Ig) heavy-chain complementarity determining region 3 (HCDR3) residues, whereas affinity maturation contributed predominantly to stabilizing the antigen-binding site conformation. Combined, our findings illustrate the power of exploring human anti-CSP antibody responses to develop tools for malaria control in the mammalian and the mosquito vector and provide a molecular basis for the structure-based design of next-generation CSP malaria vaccines.

AB - This clinical report demonstrates the use of polyetherketoneketone (PEKK) as a framework material with individually luted heat-pressed lithium disilicate glass ceramic crowns for an implant-supported complete fixed dental prosthesis (ICFDP) and a conventional complete removable dental prosthesis (CRDP). This prosthesis design provides a non-computer-aided design and computer-aided manufacturing (CAD CAM) option for the fabrication of ICFDPs and CRDPs with individualized ceramic crowns for optimal esthetics. The performance of PEKK as a framework material needs to be assessed in clinical trials. PMID- 29195816 TI - Mechanical properties of resin-ceramic CAD-CAM materials after accelerated aging. AB - STATEMENT OF PROBLEM: The development of polymer-based computer-aided design and computer-aided manufacturing (CAD-CAM) milling bocks and the limited availability of independent studies on these materials make it pertinent to evaluate changes in their mechanical properties after simulated aging to identify strengths and limitations. PURPOSE: The purpose of this in vitro study was to measure the effect of thermocycling on the flexural properties of ceramic, resin, and resin ceramic CAD-CAM materials. MATERIAL AND METHODS: Studied materials included Lava Ultimate Restorative (LVU; 3M ESPE), Enamic (ENA; VITA Zahnfabrik), Vitablocs Mark II (VM2; VITA Zahnfabrik), and Paradigm MZ100 (MZ1; 3M ESPE). Polished 4*1.2*14 mm bars (n=45 per material) were prepared from standard-size milling blocks. The 2 distilled water baths of the thermocycling apparatus were set to 5 degrees C and 55 degrees C, with a specimen immersion time of 15 seconds and transfer time of 4 seconds. Fifteen specimens from each material group were subjected to a 3-point flexural test at 3 different thermocycling intervals: 0 (control), 5000, and 10 000 cycles. The flexural test was performed over a 12-mm span with a crosshead speed of 0.5 mm/min. Data were subjected to multiple analyses of variance and the Tukey HSD post hoc tests (alpha=.05). RESULTS: Mean flexural strength values for 0, 5000, and 10 000 cycles were 133, 130, and 128 MPa for VM2; 175, 139, and 134 MPa for LVU; 154, 144, and 138 MPa for MZ1; and 149, 136, and 132 MPa for ENA. Mean flexural modulus values were 51, 52, and 54 GPa for VM2; 14, 13, and 13 GPa for LVU; 16, 15, and 15 GPa for MZ1; and 31, 30, and 31 GPa for ENA. Mean modulus of resilience values were 0.17, 0.16, and 0.15 MPa for VM2; 10.1, 0.76, and 0.72 MPa for LVU; 0.77, 0.69, and 0.62 MPa for MZ1; and 0.42, 0.31, and 0.28 MPa for ENA. A significant difference was found among the materials in the mean change of flexural strength (P<.001) and modulus of resilience (P<.05) after thermocycling. No significant difference was found among the materials in the mean change of flexural modulus after thermocycling (P=.113). CONCLUSIONS: The mean flexural strength of resin-ceramics is significantly different from that of the feldspathic ceramic control at 0 and 5000 cycles, but not at 10 000 cycles. The mean modulus of resilience of resin ceramics varies significantly after thermocycling, unlike the feldspathic ceramic control. Conversely, the mean flexural modulus of tested materials did not vary significantly after thermocycling. PMID- 29195817 TI - Radial plane tooth position and bone wall dimensions in the anterior maxilla: A CBCT classification for immediate implant placement. AB - STATEMENT OF PROBLEM: The biological and esthetic challenge of the post extraction ridge is relevant to restorative implant dentistry, most significantly in the anterior esthetic zone. Previous authors have discussed facial bone wall dimensions and classified their variations. A reclassification may be pertinent. PURPOSE: The purpose of this observational, clinical study was to introduce a new classification system for anterior maxilla tooth position with guidelines for immediate implant placement. Data for facial and palatal bone wall height and thickness are also presented. MATERIAL AND METHODS: Maxillary anterior teeth (n=591) were analyzed as viewed in the radial plane of cone beam computed tomography (CBCT) scans from 150 patients. Each tooth was classified according to its position and inclination within its alveolus (class I, middle of the alveolus; IA, thick facial bone; IB, thin facial bone; class II, retroclined; IIA, thick crestal bone; IIB, thin crestal bone; class III, proclined; class IV, facially outside bone envelope; class V, both thin facial and palatal bone with apical isthmus). Bone thickness was measured for both facial and palatal walls at the following points: crestal (A), mid-root (B), apex (C), and 4 mm beyond the apex. Bone wall height was also evaluated. RESULTS: A thin facial bone wall predominated (<=1 mm) at the crest (83%) and the mid-root point (92%). Most palatal walls were thin (<1 mm) at the crest (63%) and thick (>=2 mm) at the mid root point (98%) and apex (99%). Class I tooth position accounted for 6.1%, class II for 76.5%, class III for 9.5%, class IV for 7.3%, and class V for 0.7%. CONCLUSIONS: Maxillary anterior teeth have predominantly thin facial bones, making palatal bone thickness a crucial variable. The new classification system for radial plane tooth position is a pragmatic clinical analysis for immediate implant treatment planning. PMID- 29195818 TI - Defining the ascending ramus: A search.

PMID- 29195820 TI - Modified retention and stability criteria for complete denture wearers: A risk assessment tool for impaired masticatory ability and oral health-related quality of life. AB - STATEMENT OF PROBLEM: Some complete denture wearers report difficulty with daily activities, especially activities related to denture retention and stability. However, no standard criteria are available for professionally based assessment of complete denture quality. PURPOSE: The purpose of this clinical study was to determine the association between professionally based assessment of complete denture quality, evaluated by conventional and Chulalongkorn University (CU) modified Kapur criteria and multiple patient-based outcomes: oral health-related quality of life (OHRQoL), eating satisfaction, and masticatory performance. The sensitivity and specificity of these criteria in estimating the outcomes were investigated. MATERIAL AND METHODS: The participants were 126 individuals with removable acrylic resin complete dentures. Denture retention and stability were scored based on the Kapur method, with excellent intraobserver reliability indicated by a Kappa score of 0.91 to 0.99. The clinical quality of the complete denture was classified according to conventional and CU-modified Kapur criteria. The participants were interviewed for OHRQoL by using the Thai version of the Oral Impacts on Daily Performances (OIDP) index and responses were reported as the absence or presence of oral impacts. Participants' satisfaction eating with their dentures was determined by using a 5-point Likert scale and dichotomized into satisfied and dissatisfied categories. Masticatory performance was evaluated by the multiple sieve method of peanut mastication. After adjusting for covariates, the associations between denture quality and overall and condition specific (CS) impacts on eating and on eating satisfaction were analyzed by using binary logistic regression, while its association with masticatory performance was determined using linear regression. Goodness-of-fit post estimation was conducted to determine the sensitivity and specificity of each denture quality criterion in estimating patient-based outcomes. RESULTS: Complete denture retention and stability, evaluated by conventional and CU-modified Kapur criteria, were associated with multiple patient-based outcomes. However, denture stability showed a stronger association than retention. The CU-modified criteria assessed the quality of maxillary and mandibular dentures individually and revealed a higher sensitivity in estimating all patient-based outcomes. CONCLUSIONS: Retention and stability were important indicators in estimating the masticatory ability and OHRQoL of complete denture wearers. The CU-modified Kapur criteria can identify impaired masticatory ability and OHRQoL in complete denture wearers better than conventional criteria.

AB - Patients with ectodermal dysplasia have abnormalities of 2 or more structures that originate from the ectoderm. The oral manifestations often include the congenital absence of teeth and malformed teeth. This clinical report describes the interdisciplinary care from childhood through the definitive dental rehabilitation completed at skeletal maturation to replace the missing teeth in a patient with ectodermal dysplasia. Treatment began at 9 years of age with an implant-assisted mandibular overdenture to improve function and replace the missing mandibular teeth. Orthodontic treatment for the consolidation of space, composite resin restorations, and interim removable dental prostheses were provided to improve esthetics and replace the missing maxillary teeth. Skeletal growth was monitored, and orthognathic surgery was performed at the cessation of growth. The definitive rehabilitation consisted of a mandibular fixed dental prosthesis supported by dental implants and a maxillary removable dental prosthesis to restore the patient to esthetics and function. PMID- 29195822 TI - Effect of crosslinkers on bond strength stability of fiber posts to root canal dentin and in situ proteolytic activity. AB - STATEMENT OF PROBLEM: Improved stability of the adhesive interface can be obtained using crosslinkers. However, research on the use of crosslinkers in root dentin is lacking. PURPOSE: The purpose of this in vitro study was to evaluate the effect of crosslinkers on the proteolytic activity of root dentin and on the bond strength of resin-cemented fiber posts. MATERIAL AND METHODS: Single root canals were obtained from premolars (n=48) and endodontically treated before being divided into 4 groups: deionized water (control), 0.5 mol/L carbodiimide, 5% proanthocyanidin, or 5% glutaraldehyde. After removing the canal sealer, the dentin was etched with phosphoric acid, followed by water rinsing and the application of the crosslinkers for 60 seconds. Fiber posts were cemented using an adhesive (Single Bond 2) and resin cement (RelyX ARC). The roots were then transversally sectioned to obtain 1 mm thick specimens from the cervical, middle, and apical thirds and then aged for 24 hours or 9 months. Nine roots per group were used for the push-out test and 3 for determining the proteolytic activity of the root dentin by in situ zymography. Bond strength data were submitted to a mixed-model ANOVA and Bonferroni tests (alpha=.05). RESULTS: Only proanthocyanidin negatively affected the 24-hour bond strength. After 9 months, a significant decrease in bond strength was seen for all groups, except for the crosslinked treated specimens from the cervical third of the root canal. Intense gelatinolytic activity was detected in the control group after 24 hours but was inhibited in the crosslinker-treated groups. Proteolytic activity was also not detected after 9 months for the groups treated with the crosslinkers, irrespective of the root canal third. Conversely, proteolytic activity increased for the specimens from the control group. CONCLUSIONS: Although no proteolytic activity was detected in the hybrid layers along the entire root canal, dentin biomodification with crosslinkers was effective in preventing bond strength loss only in the cervical third.

AB - STATEMENT OF PROBLEM: Structural damage may remain even after a tooth is restored. Conventional diagnostic aids do not quantify the severity of structural damage or allow the monitoring of structural changes after restoration. PURPOSE: The purpose of this retrospective clinical study was to provide an in-depth analysis of 9 high-risk sites after restoration. The analysis followed structural defects found upon disassembly, restorative materials used, therapeutic procedures provided, current longevity, and long-term quantitative percussion diagnostics (QPD) to monitor results. The hypothesis was that QPD can be used to quantify positive and negative changes in structural stability. MATERIAL AND METHODS: Sixty sites requiring restoration were part of an institutional review board-approved clinical study. Each participant was examined comprehensively, including QPD testing, at each follow-up. Long-term changes in normal fit error (NFE) values after restoration were evaluated according to a pathology rating system established in an earlier publication. Nine highly compromised sites were chosen for further analysis and monitored for an additional 6 years. RESULTS: Of the 9 high-risk sites (NFE>0.04), 7 sites improved and 2 sites deteriorated. Potential causes for each trend were documented. CONCLUSIONS: The data support the hypothesis that QPD can be used to monitor changes in structural stability after restoration. Knowledge of changes in advance of any symptoms allows further preventive or therapeutic intervention before serious structural damage can occur. Follow-up QPD indications of site improvement can also assure the clinician of the desired structural outcome. PMID- 29195824 TI - Pseudotumor cerebri syndrome in a patient with narcolepsy type 1. AB - Type 1 narcolepsy (NT1) is a chronic primary disorder of hypersomnolence characterized by excessive daytime sleepiness, cataplexy, sleep paralysis, hypnagogic hallucinations and disrupted nocturnal sleep. NT1 is linked to hypothalamic hypocretin deficiency, strongly associated with Human Leukocyte Antigen (HLA) marker DQB1*06:02 and of probable autoimmune origin. NT1 is usually associated with increased rates of overweight and obesity, and sometimes with increases in overnight blood pressure and increased rates of hypoventilation with raised CO2 levels overnight. Many of these are predisposing factors for pseudotumor cerebri syndrome (PTCS). We present a case of a young girl with both NT1 and PTCS that responded well to treatment with acetazolamide after early identification, with improvement of headache and resolution of hypoventilation. PMID- 29195825 TI - Meta-Analysis of the Safety and Efficacy of the Oral Anticoagulant Agents (Apixaban, Rivaroxaban, Dabigatran) in Patients With Acute Coronary Syndrome. AB - The significance of adding new oral anticoagulants (NOACs) to antiplatelet therapy in patients with acute coronary syndrome (ACS) is unclear. We conducted a meta-analysis to assess the safety and efficacy of adding NOACs (apixaban, rivaroxaban, and dabigatran) to single antiplatelet agent (SAP) or dual antiplatelet therapy (DAPT) in patients with ACS. Seven randomized controlled trials were selected using PubMed or MEDLINE, Scopus, and Cochrane library (inception to August 2017). The summary measure was random effects hazard ratio (HR) with 95% confidence interval (CI). The primary safety outcome was clinically significant bleeding. The secondary efficacy outcome was major adverse cardiovascular events (MACE; composite of myocardial infarction, stroke, and all cause mortality). In 31,574 patients, addition of NOAC to SAP did not increase the risk of clinically significant bleeding (HR 0.82, 95% CI 0.56 to 1.20, p = 0.31); however, the risk of clinically significant bleeding was significantly increased with NOAC plus DAPT (HR 2.24, 95% CI 1.75 to 2.87, p < 0.001). NOACs had no statistically beneficial effect on MACE when used with SAP (HR 0.82, 95% CI 0.66 to 1.04, p = 0.10); however, a modest reduction in MACE was observed when NOACs were combined with DAPT (HR 0.86, 95% CI 0.78 to 0.93, p < 0.001). In conclusion, in patients with ACS, the addition of NOAC to DAPT resulted in increased risk of clinically significant bleeding, whereas only a modest reduction in MACE was achieved. The addition of NOACs to SAP did not result in significant reduction of MACE or increase in clinically significant bleeding. PMID- 29195826 TI - Some Cardiologists' Perspective on Past, Current, and Future of Sleep Medicine. AB - An accumulating body of evidence has highlighted the importance of sleep in cardiovascular health. Sleep apnea (SA) is a highly common condition in patients with cardiovascular comorbidities. Although awareness about the importance of diagnosis and treatment of SA among cardiologists has increased, incorporating it into daily practice has been challenging. We briefly review the current state of sleep medicine in the United States and provide views on how the cardiology community can more actively participate in SA care to deliver higher quality of care. We propose a cardiology-led patient-centered SA collaborative care model to effectively achieve this.

AB - PURPOSE: Delayed achievement of target vancomycin serum concentrations may adversely affect clinical outcomes. The objective of this retrospective study was to explore the real frequency of loading dose use and to evaluate the impact of loading dose for the achievement of vancomycin PK/PD target in adult patients treated with intermittent vancomycin. As a secondary aim we determined optimal vancomycin loading dose based on individual pharmacokinetic calculations. METHODS: Vancomycin pharmacokinetic models were computed using two-compartmental analysis. Based on these models AUC24 were calculated. Unpaired t-test was used to compare AUC24 achieved in patients treated with and without vancomycin loading dose. RESULTS: Vancomycin loading dose was administered only in 17.8% patients. Volume of distribution and clearance median values (interquartile range) for vancomycin in whole study population (n = 45) were 0.69 (0.55-0.87) L/kg and 0.0304 (0.0217-0.0501) L/h/kg, respectively. The AUC24 was significantly higher in patients taking loading dose compared with the group without loading dose: mean (SD) AUC24 was 496 (101) vs. 341 (77) mg h/L. Proportion of patients reaching PK/PD goal was 87.5% and 24.3% with and without loading dose administration, respectively. Considering individual pharmacokinetic parameters optimal vancomycin loading dose was 27.5 mg/kg of body weight. CONCLUSIONS: Loading dose administration plays crucial part in rapid attainment of vancomycin PK/PD target in adult patient treated with intermittent vancomycin, although it is not frequently used in clinical practise. The optimal loading dose of 25-30 mg/kg of body weight should be routinely administered to adult patients treated with intermittent vancomycin. PMID- 29195830 TI - Retrograde intrarenal surgery using ureteral access sheaths is a safe and effective treatment for renal stones in children weighing <20 kg. AB - INTRODUCTION: Surgical treatment of pediatric kidney stones has changed dramatically in recent years because of the miniaturization of surgical instruments and the availability of intracorporeal lithotripters. The retrograde intrarenal surgery (RIRS) technique is nowadays considered an effective and safe procedure but studies in very young children are lacking and use of a ureteral access sheath (UAS) has also been debated. OBJECTIVE: To assess safety and efficacy of RIRS using UAS in children weighing < 20 kg. MATERIALS AND METHODS: Data from 13 children weighing <20 kg who underwent RIRS for renal stones were collected. A Double-J stent was positioned 14 days before surgery. Demographics, stone location, stone number and composition, stone-free status (SFS) and complications were evaluated. Descriptive statistics were applied to describe the cohort. RESULTS: Thirteen patients, age 3.91 +/- 1.8 years (mean +/- SD), underwent 16 RIRS. Mean patient weight and stone burden were 14.88 +/- 3.81 kg (range 10-20 kg) and 15.5 +/- 3.8 mm (median 16 mm), respectively. A UAS was used in 15 out of 16 (93.8%) procedures. SFS was achieved in 81.3% of cases after the first procedure and 100% after auxiliary procedures. Postoperative urinary tract infections with fever (Clavien II) were observed in two (12.5%) patients. Hydrocalyx (Clavien IIIb) was noted in one (6.3%) patient. Patients with stones located in the lower polar calices (p = 0.024) and with mixed composition (p = 0.036) had a greater prevalence of complications than those with calculi of other compositions located in other sites. After a mean follow-up of 22.4 months no cases of ureteral strictures or vesicoureteral reflux were observed (Table). DISCUSSION: The current findings support previous evidence showing safety and efficacy of RIRS with use of the UAS in pre-stented very young children. In our experience RIRS seems to be an effective and safe option with a stone-free rate of 81.3% and only 1 severe complication (Clavien-Dindo grade IIIb) and no long term complications. This study is, to date, the first to examine the safety and efficacy of RIRS using UAS for the treatment of intrarenal stones in a selected cohort of pre-school patients weighing <20 kg. CONCLUSIONS: RIRS using UAS is an effective and safe procedure for treating kidney stones in pre-school patients weighing <20 kg without complications at both short and long term follow up. Stones of mixed composition located in the lower polar calices are associated with a greater risk of postoperative complications. PMID- 29195831 TI - Bladder exstrophy closure in the newborn period with external pelvic fixation performed without osteotomy: A preliminary report. AB - BACKGROUND: Successful primary bladder closure is the most crucial element for urinary continence in patients with classic bladder exstrophy (CBE). In the newborn period, bladder closure can be performed in the first 48 h without pelvic osteotomy or external fixation, but requires postoperative lower extremity immobilization (i.e., spica cast, Bryant's or Buck's traction). OBJECTIVE: To present a novel surgical approach for primary bladder closure for CBE using two pin external fixation without pelvic osteotomy, and without postoperative lower extremity immobilization. STUDY DESIGN: A retrospective chart review of patients with CBE was performed at the current institution from 2000 to 2016, including all primary bladder closures with external fixation and without osteotomy or lower extremity immobilization. Patients were discharged with the external fixator in place, which was later removed in clinic. Baseline clinical and demographic variables, and follow-up data were recorded. RESULTS: Thirteen patients were analyzed; eight (61.5%) were male. Pre-operative intersymphysial distance was 3.68 +/- 1.0 cm (2.0-5.0). Mean follow-up was 56.8 +/- 40.3 months (10-131). One patient had a partial bladder neck dehiscence, due to pin displacement on postoperative day 1: he had the lowest gestational age of 34 weeks (Summary table). DISCUSSION: This approach used external fixation to bring the pubic bones together intra-operatively, and to decrease the tension in closing the pelvic ring and abdominal wall without osteotomy. External fixation with osteotomy and long-term immobilization, or using a spica cast without osteotomy offered the added advantage of improved wound care, due to lack of lower limb immobilization, less patient discomfort, and facilitation of mother/caregiver and newborn bonding. CONCLUSION: The two-pin external fixator without osteotomy as an adjunct to primary bladder closure in CBE patients was technically feasible. At the current institution this approach had an equivalent success rate to previous reports in the literature for primary bladder closure, decreased the length of hospital stay, and precluded the need for lower extremity immobilization. Early data for bladder capacity were encouraging. PMID- 29195832 TI - Variation in the use of laparoscopy with inguinal hernia repairs in a sample of pediatric patients at children's hospitals. AB - INTRODUCTION/BACKGROUND: Metachronous contralateral inguinal hernias (MCH) occur in approximately 10% of pediatric patients following unilateral inguinal hernia repairs (UIHR). Laparoscopic evaluation of the contralateral internal ring is a method of identifying high-risk individuals for prophylactic contralateral exploration and repair. OBJECTIVE: The objective of this study was to assess variation in utilization of diagnostic laparoscopy, and report costs associated with the evaluation of a contralateral patent processus vaginalis during hernia repair in pediatric hospitals. STUDY DESIGN: The Pediatric Health Information System database was searched to identify outpatient surgical encounters for pediatric patients with a diagnosis of inguinal hernia during a 1-year period (2014). Records were identified that contained diagnostic codes for unilateral or bilateral inguinal hernia in combination with a procedure code for open hernia repair with or without diagnostic laparoscopy. RESULTS: After exclusions there were 3952 hernia repairs performed at 30 hospitals; median age was 4 years (IQR 1 7), 78.8% were male, and 64.9% Caucasian. Three-quarters (76.7%) had UIHR, 8.6% had unilateral repairs with laparoscopy (UIHRL), 12.2% had bilateral inguinal hernia repairs (BIHR), and 2.4% had bilateral repairs with laparoscopy (BIHRL). Where laparoscopy was used, 78% resulted in a unilateral repair and 22% in a bilateral procedure. The percent of patients undergoing laparoscopy varied from 0 to 57% among hospitals, and 0-100% among surgeons. Pediatric surgeons were more than three times more likely to perform a diagnostic laparoscopy compared with pediatric urologists. Median adjusted costs were $2298 (IQR 1659-2955) for UIHR, $2713 (IQR 1873-3409) for UIHRL, $2752 (IQR 2230-3411) for BIHR, and $2783 (IQR 2233-3453) for BIHRL. Median costs varied over two-fold among hospitals ($1310 4434), and over four-fold among surgeons ($948-5040). DISCUSSION: Data suggested that <10% of patients with clinically unilateral inguinal hernias developed MCH. A negative diagnostic laparoscopy ensured that 0.9-1.31% developed MCH. However, up to 30% of patients underwent contralateral exploration/repair when diagnostic laparoscopy was used. The current study found increased costs associated with the use of laparoscopy, with considerable variation in costs among surgeons and hospitals. These data elucidate competing financial and clinical consequences associated with the use of diagnostic laparoscopy with clinically unilateral hernias. CONCLUSIONS: Variation existed in the use of laparoscopy during inguinal hernia repairs and associated costs within the current sample from children's hospitals in the United States. The additional costs of laparoscopic evaluation must be considered against the clinical utility and therapeutic consequences of identifying individuals with a higher risk of metachronous contralateral inguinal hernia. PMID- 29195833 TI - Lutein levels in arterial cord blood correlate with neuroprotein activin A in healthy preterm and term newborns: A trophic role for lutein? AB - BACKGROUND: Lutein (LT) is a naturally occurring xanthophyll carotenoid most predominant in the central nervous system (CNS), but its neurotrophic role is still debated. We therefore investigated whether cord blood concentrations correlated with a well-established neurobiomarker, namely activin A. METHODS: We conducted a prospective study on the distribution of LT and activin A in arterial cord blood of healthy preterm (n=50) and term (n=82) newborns according to weeks of gestational age (wGA) and gender. RESULTS: LT and activin A showed a pattern of concentration characterized by higher levels (P<0.01, for all) at 33-36 wGA followed by a progressive decrease (P<0.01, for all) from 37 onwards with a dip at term. Both LT and activin A were gender-dependent with significantly (P<0.01, for all) higher levels in all recruited females and after sub-grouping for preterm and term births. LT (R=0.33; P<0.001) correlated with wGA at sampling. There were significant positive correlations between lutein and activin A in male (R=0.93; P<0.001) and female (R=0.89; P<0.001) groups. CONCLUSIONS: The present data showing a correlation between LT and activin A support the notion of a neurotrophic role gender-dependent for LT and open the way to further investigations correlating LT with well-established biochemical markers of CNS development/damage. PMID- 29195834 TI - Diacerein alleviates kidney injury through attenuating inflammation and oxidative stress in obese insulin-resistant rats. AB - A link between inflammation with obesity and metabolic syndrome has been found in patients with chronic kidney disease (CKD). Diacerein is an anthraquinone used to treat osteoarthritis that exerts anti-inflammatory action by inhibiting the synthesis and activity of proinflammatory cytokines. This study aimed to investigate the protective effect of diacerein on renal function and renal organic anion transporter 3 (Oat3) function in obese insulin-resistant condition. Obese insulin-resistant rats were induced by feeding a high-fat diet in male Wistar rats for 16 weeks. Diacerein or metformin (positive control) (30mg/kg/day) was administered orally for 4 weeks after insulin resistance had been confirmed. Obese insulin-resistant rats showed an impaired renal function as indicated by the increased serum creatinine and microalbuminuria along with the decreased renal Oat3 function and expression. Importantly, diacerein treatment not only improved insulin resistance but also restored renal function. The decreased renal malondialdehyde level, expressions of PKCalpha, angiotensin 1 receptor (AT1R), Nrf2, and HO-1, and increased expression of SOD2 were observed in diacerein treatment group, indicating the attenuation of renal oxidative stress condition. Moreover, renal inflammation and renal damage were also alleviated in diacerein treated rats. Our results demonstrated for the first time that diacerein was effective to improve renal function and renal Oat3 function in obese insulin resistance condition mediated by suppressing renal oxidative stress and inflammation. These findings suggest that anti-inflammatory agents can be used therapeutically to improve metabolic disorder and prevent organ dysfunctions in pre-diabetic condition. PMID- 29195835 TI - Absence of the biliverdin reductase-a gene is associated with increased endogenous oxidative stress. AB - Bilirubin, a byproduct of heme catabolism, has been shown to be an effective lipid-soluble antioxidant in vitro. Bilirubin is able to inhibit free radical chain reactions and protects against oxidant-induced damage in vitro and ex vivo. However, direct evidence for bilirubin's antioxidant effects in vivo remains limited. As bilirubin is formed from biliverdin by biliverdin reductase, we generated global biliverdin reductase-a gene knockout (Bvra-/-) mice to assess the contribution of bilirubin as an endogenous antioxidant. Bvra-/- mice appear normal and are born at the expected Mendelian ratio from Bvra+/- x Bvra+/- matings. Compared with corresponding littermate Bvra+/+ and Bvra+/- animals, Bvra /- mice have green gall bladders and their plasma concentrations of biliverdin and bilirubin are approximately 25-fold higher and 100-fold lower, respectively. Naive Bvra-/- and Bvra+/+ mice have comparable plasma lipid profiles and low molecular weight antioxidants, i.e., ascorbic acid, alpha-tocopherol and ubiquinol-9. Compared with wild-type littermates, however, plasma from Bvra-/- mice contains higher concentrations of cholesteryl ester hydroperoxides (CE-OOH), and their peroxiredoxin 2 (Prx2) in erythrocytes is more oxidized as assessed by the extent of Prx2 dimerization. These data show that Bvra-/- mice experience higher oxidative stress in blood, implying that plasma bilirubin attenuates endogenous oxidative stress. PMID- 29195836 TI - Is the risk of antipsychotic polypharmacy discontinuation dependent on the agents used? AB - This study assesses the risks and benefits of switching from two to one antipsychotic among participants on two non-clozapine oral antipsychotics, and among those on combinations involving either clozapine or an injectable antipsychotic. Ninety adult participants with schizophrenia or schizoaffective disorder were assigned to stay on polypharmacy or to switch to monotherapy. Half of these participants were receiving combinations of non-clozapine oral antipsychotics and half were receiving combinations involving either clozapine or an injectable antipsychotic. Participants were assessed every 60 days for one year. We examined differences in symptom and side effect trajectories as a function of group assignment and time for both medication groups. Participants who switched from two to one non-clozapine oral antipsychotic experienced significant increases in symptoms relative to stay participants. They also saw significant side effect benefits. Switch participants on combinations involving clozapine or an injectable antipsychotic did not differ over time from stay participants on either symptom or side effect measures. It appears that patients on these combinations can be safely switched to monotherapy. While there may be symptom related risks associated with switching patients on combinations of non clozapine oral antipsychotics, there are significant health related benefits. Clozapine or injectable antipsychotic monotherapy are recommended options. PMID- 29195837 TI - Evaluation of the efficacy of tongue-lip adhesion in Pierre Robin sequence. AB - OBJECTIVE: Tongue-lip adhesion may be used to relieve obstructive sleep apnoea in infants with Pierre Robin sequence (PRS), but only a few studies have objectively evaluated its efficacy. The purpose of this study was to evaluate the results of tongue-lip adhesion by polysomnography. MATERIEL AND METHODS: A single-centre retrospective study was conducted in infants with PRS treated by tongue-lip adhesion from 2004 to 2015, in whom at least laryngotracheal endoscopy and polysomnography were performed. The variables collected were the syndromic diagnosis, demographic data, respiratory management before tongue-lip adhesion, symptoms, and additional airway interventions. Obstructive sleep apnoea was classified into 3 groups according to severity. Polysomnography was performed one month after tongue-lip adhesion. Statistical analysis was performed with Wilcoxon signed-rank test with a limit of statistical significance of P<0.005. RESULTS: Thirty-seven subjects in whom tongue-lip adhesion was performed at a mean age of 45 days (8 to 210 days) were included. Thirty-one patients had isolated PRS and 6 patients had associated anomalies. All patients had confirmed severe obstructive sleep apnoea. All patients required respiratory support prior to surgery: 8 intubated patients, 15 patients with noninvasive ventilation and 14 patients with nasopharyngeal airways. Eight patients had bradycardia before tongue-lip adhesion. All parameters were improved on postoperative polysomnography: oxygen saturation, hypercapnia, apnoea-hypopnoea index, bradycardia (P<0.005). Only 8 patients had persistent severe obstructive sleep apnoea and required tracheostomy (n=5) or noninvasive ventilation (n=3). No significant correlation was observed between treatment success and any predictive variables. CONCLUSION: Tongue-lip adhesion improved airway obstruction in all infants with PRS and resolved obstructive sleep apnoea in 29 patients. However, 8 patients required additional airway interventions. PMID- 29195838 TI - A phenomenological analysis of eco-evolutionary coupling under dilution. AB - Evolutionary dynamics experienced by mixed microbial populations of cooperators and cheaters has been examined in experiments in the literature using a protocol of periodic dilution to investigate the properties of resilience and adaptability to environmental changes. Data depicted on an appropriate phase diagram indicate, among other features, a stable equilibrium point at which cooperators and cheaters coexist (Sanchez and Gore, 2013). We present here a phenomenological analysis of these data focusing on an eco-evolutionary-game perspective. To that end, we work on an extension of the model proposed in Tao and Cressman (2007). It's original version takes into account changes of the total population density while the individuals experience a pairwise Prisoners Dilemma game. The extension devised here contains a dilution parameter to conform with the experimental procedure, in addition to a term accounting for Allee effects. In contrast to other descriptions proposed in similar contexts, however, the model here does not account for assortative encounters, group or kin selection. Nonetheless, it describes surprisingly well both qualitatively and quantitatively the features of the observed phase diagram. We discuss these results in terms of the behavior of an effective payoff matrix defined accordingly. PMID- 29195839 TI - The ventromedial hypothalamic nucleus plays an important role in anxiolytic-like effect of neuropeptide S. AB - Neuropeptide S (NPS), the endogenous neuropeptide ligand of NPSR, has been reported to regulate anxiety-related behavior involved in multiple brain regions, including amygdale, locus coeruleus and Barrington's nucleus. However, little research has been conducted on the anxiolytic-like behaviors of NPS on the hypothalamus, which was an important area in defensive behavior. Here, we investigated a role of hypothalamus in anxiolytic-like behaviors of NPS. We found that NPSR protein of mouse distributed mainly in the ventromedial hypothalamus (VMH). And in the single prolonged stress model (SPS), the results showed that NPS mRNA of the mice exposed to SPS was significantly higher than control, while NPSR mRNA was remarkable lower than control in hypothalamus. Further studies found that NPS intra-VMH infusion dose-dependently (1, 10 and 100pmol) induced anxiolytic effects, using elevated plus maze and open field tests. These anxiolytic effects could be blocked by NPSR antagonist (SHA68), but not by picrotoxin (a GABAA receptor antagonist) and sacolfen (a GABAB receptor antagonist). Meanwhile, our data showed that the expression of c-Fos was significantly increased in VMH after NPS delivered into the lateral ventricles. These results cast a new light on the hypothalamic nucleus in the anxiolytic-like effect of NPS system.

PMID- 29195841 TI - Incidental pulmonary nodules in emergent coronary CT angiography for suspected acute coronary syndrome: Impact of revised 2017 Fleischner Society Guidelines. AB - BACKGROUND: Pulmonary nodules (PN) are frequently detected incidentally during coronary computed tomography angiography (CTA). We evaluated whether the 2017 Fleischner Society guidelines may result in a decrease of follow-up testing of incidental PN as compared to prior guidelines in patients undergoing coronary CTA. METHODS: We conducted a retrospective study of a registry of emergency department patients who underwent coronary CTA for acute coronary syndrome assessment between 2012 and 2017. Based on guidelines, patients <35 years, history of cancer, or prior exams showing stability of PN were excluded. Patients >60 years, history of smoking, irregular/spiculated PN morphology, or PN size >20 mm were classified as high-risk for lung cancer. Radiological findings pertaining to PN were identified (PN size, morphology, quantity) through review of radiology reports. PN follow-up recommendations were established using 2017 Fleischner Society Guidelines and compared with prior guidelines for solid (2005) and subsolid (2013) PN. Data were analyzed with Student's t-test. RESULTS: The registry included 2066 patients (female 45.1%, 52.9 +/- 11.0 years), of which 578 (28.0%) reported PN. 438 of those (21.2%) were eligible for guideline-based follow-up evaluation. 205 (4 6.8%) were classified as high-risk for lung cancer. 2017 guidelines reduced the number of individuals requiring follow-up by 64.5%, from 264 (12.8%) to 94 patients (4.5%) when compared to prior guidelines (p < 0.001). The minimum number of follow-up chest CTs decreased by 55.8% from 430 to 190 (p < 0.001). CONCLUSION: Application of the 2017 Fleischner Society Guidelines resulted in a significant decrease of follow-up testing for incidental PN in patients undergoing coronary CTA for suspected acute coronary syndrome. PMID- 29195840 TI - Membrane estrogen receptor signaling impacts the reward circuitry of the female brain to influence motivated behaviors. AB - Within the adult female, estrogen signaling is well-described as an integral component of the physiologically significant hypothalamic-pituitary-gonadal axis. In rodents, the timing of ovulation is intrinsically entwined with the display of sexual receptivity. For decades, the importance of estradiol activating intracellular estrogen receptors within the hypothalamus and midbrain/spinal cord lordosis circuits has been appreciated. These signaling pathways primarily account for the ability of the female to reproduce. Yet, often overlooked is that the desire to reproduce is also tightly regulated by estrogen receptor signaling. This lack of emphasis can be attributed to an absence of nuclear estrogen receptors in brain regions associated with reward, such as the nucleus accumbens, which are associated with motivated behaviors. This review outlines how membrane localized estrogen receptors affect metabotropic glutamate receptor signaling within the rodent nucleus accumbens. In addition, we discuss how, as estrogens drive increased motivation for reproduction, they also produce the untoward side effect of heightening female vulnerability to drug addiction. PMID- 29195843 TI - Influence of irregular heart rhythm on radiation exposure, image quality and diagnostic impact of cardiac computed tomography angiography in 4,339 patients. Data from the German Cardiac Computed Tomography Registry. AB - BACKGROUND: Coronary computed tomography angiography (coronary CTA) provides non invasive evaluation of the coronary arteries with high precision for the detection of significant coronary artery disease (CAD). AIM: To investigate whether irregular heart rhythm including atrial fibrillation and premature beats during data acquisition influences (i) radiation and contrast media exposure, (ii) number of non-evaluable coronary segments and (iii) diagnostic impact of coronary CTA. METHODS: Twelve tertiary care centers with >=64 slice CT scanners and >=5 years of experience with cardiovascular imaging participated in this registry. Between 2009 and 2014, 4339 examinations were analysed in patients who underwent clinically indicated coronary CTA for suspected CAD. Clinical and epidemiologic data were gathered from all patients. In addition, clinical presentation, heart rate and rhythm during the scan, Agatston score, radiation and contrast media exposure and the diagnostic impact of coronary CTA were systematically analysed. RESULTS: Of 4339 patients in total, 260 (6.0%) had irregular heart rhythm, whereas the remaining 4079 (94.0%) had stable sinus rhythm. Patients with irregular heart rhythm were older (63.2 +/- 12.5yrs versus 58.6 +/- 11.4yrs. p < 0.001), exhibited a higher rate of pathologic stress tests before CTA (37.1% versus 26.1%, p < 0.01) and higher heart rates during CTA compared to those with sinus rhythm (62.5 +/- 11.6bpm versus 58.9 +/- 8.5bpm, p < 0.001). Both contrast media exposure and radiation exposure were significantly higher in patients with irregular heart rhythm (90 mL (95%CI = 80-110 mL) versus 80 mL (95%CI = 70-90 mL) and 6.2 mSv (95%CI = 2.5-11.7) versus 3.3 mSv (95%CI = 1.7-6.9), p < 0.001 for both). Coronary CTA excluded significant CAD less frequently in patients with irregular heart rhythm (32.9% versus 44.8%, p < 0.001). This was attributed to the higher rate of examinations with at least one non-diagnostic coronary segment in patients with irregular heart rhythm (10.8% versus 4.6%, p < 0.001). Subsequent invasive angiography could be avoided in 47.2% of patients with irregular heart rhythm compared to 52.9% of patients with sinus rhythm (p = NS), whereas downstream stress testing was recommended in 3.2% of patients with irregular heart rhythm versus 4.0% of patients with sinus rhythm (p = NS). CONCLUSION: A significant number of patients scheduled for coronary CTA have irregular heart rhythm in a real-world clinical setting. In such patients, heart rate during coronary CTA is higher, possibly resulting in (i) higher radiation and contrast agent exposure and (ii) more frequent coronary CTA examinations with at least one non-diagnostic coronary artery segment. However, this does not seem to lead to increased downstream stress testing or subsequent invasive procedures. PMID- 29195844 TI - Leaflet thrombosis following transcatheter aortic valve implantation. AB - BACKGROUND: Transcatheter aortic valve implantation (TAVI) is increasingly being offered to high-risk patients with symptomatic aortic valve stenosis. Recent reports have suggested a high incidence of subclinical leaflet thrombosis following bioprosthestic aortic valve replacement. We report the frequency and clinical presentation of leaflet thrombosis identified by cardiac CT in patients referred for follow-up contrast enhanced CT angiography following TAVI. METHODS: 91 consecutive patients referred for follow-up contrast-enhanced CT angiography following TAVI were screened for inclusion in this analysis. Out of these, 13 patients were excluded. All CT examinations were performed using a 2nd or a 3rd generation dual-source system (Somatom Definition Flash/Force, Forchheim, Germany). In all patients, retrospectively ECG-gated spiral acquisition with tube modulation was performed to allow for assessment of leaflet motion. All prostheses were analyzed for presence of leaflet thrombosis defined as hypo attenuated leaflet thickening with or without leaflet restriction. Post procedural antithrombotic regimen as well as symptom status was documented in all patients. RESULTS: 78 consecutive patients (35 males, 81 +/- 4 years) were analyzed. TAVI had been performed in all patients (76 transfemoral access, 2 transapical access) with either balloon-expandable prostheses (4 Sapien XT, 64 Sapien 3) or self-expandable prostheses (5 SJM Portico, 5 Symetis Acurate). Follow-up CT angiography was performed at a median of 4 months following index procedure (Interquartile range 1 month). Leaflet thrombosis was detected in 18 patients (23%, 14 Sapien 3, 1 Sapien XT, 2 SJM Portico, 1 Symetis Acurate). In patients with leaflet thickening on CT, only 11% were on either oral anticoagulation or new oral anticoagulants versus 50% for patients with no leaflet thickening (p 0.002). In patients with leaflet thrombosis, 3 leaflets were affected in 5 patients, 2 leaflets in 5 patients and in 8 patient only 1 leaflet was affected. Clinical symptoms (angina, dyspnea or both) were reported in 2/18 patients with leaflet thrombosis (11%) and in both patients a significant increase of the mean echocardiographic gradient over the prosthesis was documented. The peak and mean echocardiographic gradients obtained at the day of CT examination was significantly higher in symptomatic patients versus asymptomatic patients (peak 46 +/- 7 vs. 23 +/- 11 mmHg, mean 29 +/- 7 vs. 12 +/- 6 mmHg, p = 0.01 and 0.002, respectively). Follow-up CT was available for 4 patients with complete resolution of the hypo-attenuated leaflet thickening following treatment. CONCLUSION: Leaflet thrombosis following TAVI is a relatively frequent finding in patients referred for contrast enhanced CT angiography following TAVI. In the majority of patients it follows a subclinical course and is substantially more frequent in individuals who are not on oral anticoagulation. However, in patients with relevant increase in prosthetic gradients, symptomatic presentations are possible. PMID- 29195845 TI - December 2017. PMID- 29195846 TI - Association of fibulin-3 concentrations with the presence and severity of knee osteoarthritis: A cross-sectional study. AB - BACKGROUND: Fibulin-3, a member of the extracellular matrix glycoproteins family, negatively regulates chondrocyte differentiation. This study aims to assess the correlation of fibulin-3 concentrations with the presence and severity of knee osteoarthritis. METHODS: This cross-sectional study was performed in a population of 209 knee osteoarthritis subjects who received hyaluronic acid treatment and 165 healthy controls. Knee osteoarthritis diagnosis was made according to the criteria of the American College of Rheumatology. Osteoarthritis severity was scored by the Kellgren-Lawrence grading method. Synovial fluid was obtained from the knees of osteoarthritis subjects who received the treatment of hyaluronic acid injection for the first time. Serum and synovial fluid fibulin-3 concentrations were examined by enzyme-linked immunosorbent assay method. RESULTS: Mann-Whitney U-test showed that there were higher serum fibulin-3 concentrations in the case group compared with the controls. Higher serum and synovial fluid fibulin-3 concentrations were found in knee osteoarthritis subjects compared with those with Kellgren-Lawrence grades 2 and 3. Knee osteoarthritis subjects with Kellgren-Lawrence grade 3 had higher serum and synovial fluid fibulin-3 concentrations compared with those with Kellgren Lawrence grade 2. Serum and synovial fluid fibulin-3 concentrations were significantly correlated with Kellgren-Lawrence grading after Pearson correlation analysis (r=0.532, P<0.001 and r=0.613, P<0.001). Multinomial logistic regression analysis demonstrated a significant association between serum and synovial fluid fibulin-3 concentrations with Kellgren-Lawrence grades (P<0.001 and P<0.001). CONCLUSION: Serum and synovial fluid fibulin-3 concentrations were correlated with the presence and severity of knee osteoarthritis. PMID- 29195847 TI - Trochanteric Bursitis Following Primary Total Hip Arthroplasty: Incidence, Predictors, and Treatment. AB - BACKGROUND: Trochanteric bursitis (TB) remains a common complication after total hip arthroplasty (THA), with an incidence between 3% and 17%, depending on the surgical approach, with the posterior approach (PA) being relatively protective compared to the lateral approach. The purposes of this study were to determine the incidence of TB after primary THA, identify potential risk factors for TB, and examine the utility of different modes of treatment. METHODS: Retrospective cohort data of 990 primary THAs performed in a single institution, including 613 PAs and 377 direct anterior approaches (DAAs), were analyzed. Data abstracted included demographic data, operative diagnosis, comorbidities, radiographic assessment, and other specific predictors of interest that were compared between patients diagnosed with TB following THA and controls. RESULTS: The incidence of TB following primary THA was 5.4% (54/990) for the entire cohort. The incidence did not differ significantly between the PA and DAA (5% vs 6.1%, respectively; P = .47). Charlson comorbidity index and American Society of Anesthesiology did not differ significantly in the TB group. Lumbar spinal stenosis and history of past smoking were significantly more common in patients who developed TB (P = .03, P = .01, respectively), but did not continue to be significant risk factors on multivariate analysis. All patients were treated nonoperatively by the time of final follow-up. Seventy-four percent required a local steroid injection and 30% required treatment with more than one modality. CONCLUSION: The occurrence of TB is not influenced by the surgical approach (PA or DAA), and could not be predicted by specific comorbidities or radiographic measurements. However, it can be effectively treated conservatively in most cases. PMID- 29195848 TI - Does Surgical Approach Affect Outcomes in Total Hip Arthroplasty Through 90 Days of Follow-Up? A Systematic Review With Meta-Analysis. AB - BACKGROUND: The choice between anterior approach (AA) and posterior approach (PA) in primary total hip arthroplasty (THA) is controversial. Previous reviews have predominantly relied on data from retrospective studies. METHODS: This systematic review included prospective studies comparing postoperative outcomes through 90 days of AA vs PA in primary THA. Outcomes were pain severity, narcotic usage, hip function using Harris Hip Score, and complications. Random effects meta-analysis was performed for all outcomes. Efficacy data were reported as standardized mean difference (SMD) where values of 0.2, 0.5, 0.8, and 1.0 were defined as small, medium, large, and very large effect sizes, respectively. Complications were reported as the absolute risk difference (RD) where a positive value implied higher risk with AA and a lower value implied lower risk with AA. RESULTS: A total of 13 prospective comparative studies (7 randomized) with patients treated with AA (n = 524) or PA (n = 520) were included. The AA was associated with lower pain severity (SMD = -0.37, P < .001), lower narcotic usage (SMD = -0.36, P = .002), and improved hip function (SMD = 0.31, P = .002) compared to PA. No differences between surgical approaches were observed for dislocation (RD = 0.2%, P = .87), fracture (RD = 0.2%, P = .87), hematoma (RD = 0%, P = .99), infection (RD = 0.2%, P = .85), thromboembolic event (RD = -0.9%, P = .42), or reoperation (RD = 1.3%, P = .26). Conclusions of this study were unchanged when subjected to sensitivity analyses. CONCLUSION: In this systematic review and meta-analysis of prospective studies comparing postoperative outcomes through 90 days of AA vs PA in primary THA, patients treated with AA reported less pain, consumed fewer narcotics, and reported better hip function. No statistical differences in complication rates were detected between AA and PA. Ultimately, the choice of surgical approach in primary THA should consider preference and experience of the surgeon as well as preference and anatomy of the patient. PMID- 29195849 TI - Cementless Posteriorly Stabilized Total Knee Arthroplasty: Seven-Year Minimum Follow-Up Report. AB - BACKGROUND: The purpose of this study is to evaluate (1) implant survivorship; (2) patient outcomes; (3) complications; and to (4) perform a radiographic analysis of cementless posteriorly stabilized total knee arthroplasty (TKA) patients at a minimum of 7-year follow-up. METHODS: Our original cohort was composed of 114 consecutive cementless posteriorly stabilized total knee arthroplasties (110 patients) performed by a single surgeon between 2008 and 2010. Since our original report, 4 (1 bilateral) patients died and 2 were lost to follow-up. Therefore, there were 104 patients who had 107 knees available for final follow-up. The final cohort included 43 men and 61 women, who had a mean age of 69 years (range 47-87) and were followed from 7 to 9 years (mean 8 years). Patient outcomes and complications were obtained from electronic medical records. Radiographic assessment was done using the Knee Society Radiographic Evaluation System. RESULTS: The all-cause survivorship was 98% (95% confidence interval 1.01 0.96). Since the original report, there has been 1 post-traumatic loosening of the tibial baseplate, and 1 revision for instability. There were no femoral revisions or patella revisions. The mean Knee Society pain score was 93 points (range 80-100) and the function score was 78 points (range 68-95). Excluding revisions, there was no evidence of progressive loosening of any implant components. CONCLUSION: Based on these 7-year minimum follow-ups, femoral, tibial, and patellar cementless hydroxylapatite-coated beaded implants perform well at up to 9 years postoperatively and offer surgeons and patients a cementless option that may provide long-lasting biological fixation.

PMID- 29195851 TI - Effect of the Referencing System on the Posterior Condylar Offset and Anterior Flange-Bone Contact in Posterior Cruciate-Substituting Total Knee Arthroplasty. AB - BACKGROUND: The effect of referencing system on posterior condylar offset (PCO) after total knee arthroplasty (TKA) is still controversial. Moreover, there is a lack of concern about the anterior flange-bone contact according to the referencing system. METHODS: One hundred four TKAs using the anterior referencing (AR) system and 107 TKAs using the posterior referencing (PR) system were analyzed with 2-year follow-up. The PCO, PCO ratio (PCOR), and contact at the anterior flange-bone interface were compared between the 2 groups. The flexion and extension gaps and the degree of medial release were measured, and clinical outcomes were evaluated. Finally, the correlation between changes in PCO and knee flexion angle was analyzed. RESULTS: The mean postoperative PCO and PCOR were significantly larger in the PR group than in the AR group. Incomplete contact between the anterior flange and anterior femur occurred more frequently in the AR group than in the PR group (48.1% vs 13.1%, P < .001). The medial and lateral flexion gaps were significantly larger in the AR group than in the PR group. The groups showed no differences in soft tissue release, degree of flexion, and clinical scores. In both groups, there was no correlation between postoperative change of PCO and improvement in flexion. CONCLUSION: The PR system produced larger PCO and PCOR, and smaller flexion gap compared to the AR system. Additionally, the PR group showed more favorable contact between the anterior flange and anterior femur. However, these differences were not related to the degree of soft tissue release and clinical outcomes.

PMID- 29195854 TI - Hypothermia in Total Joint Arthroplasty: A Wake-Up Call. AB - BACKGROUND: Total joint patients are particularly vulnerable to perioperative hypothermia (PH) (combined effects of anesthesia, radiation, and convective heat loss from exposed skin surfaces and cool temperatures in the operating room). There are limited studies on PH in these patients. METHODS: In a retrospective review of 204 patients undergoing primary hip and 179 undergoing primary knee replacement surgeries, time and temperature parameters were collected from the electronic health records from preoperative and postoperative recovery room nursing assessments, intraoperative anesthesia records, and floor nursing notes. Basic patient demographic data was recorded. Chi-squared and paired t-tests were used to compare between hypothermic and normothermic groups. RESULTS: At the time of incision, 60 of 179 (34%) total knee arthroplasty (TKA) patients and 80 of 204 (39%) total hip arthroplasty (THA) patients were hypothermic. In THA patients, 65% remained hypothermic for the duration of anesthesia compared to 33% of TKA patients. The largest drop in core body temperature in both THA and TKA patients occurred between preoperative holding and induction of anesthesia. In THA patients, spinal anesthesia had a significantly higher occurrence of PH. No significant patient factor was found to increase risk. CONCLUSION: Emphasis on preoperative holding protocols, decreasing time from operating room entry to incision, and increasing ambient room temperature could reduce risk of hypothermia in total joint replacement patients. PMID- 29195855 TI - Modeling of the effects of IL-17 and TNF-alpha on endothelial cells and thrombus growth. AB - Rheumatoid and psoriatic arthritis are chronic inflammatory diseases, with massive increase of cardiovascular events (CVE), and contribution of the cytokines TNF-alpha and IL-17. Chronic inflammation inside the joint membrane or synovium results from the activation of fibroblasts/synoviocytes, and leads to the release of cytokines from monocytes (Tumor Necrosis Factor or TNF) and from T lymphocytes (Interleukin-17 or IL-17). At the systemic level, the very same cytokines affect endothelial cells and vessel wall. We have previously shown [1,2] that IL-17 and TNF-alpha, specifically when combined, increase procoagulation, decrease anticoagulation and increase platelet aggregation, leading to thrombosis. These results are the basis for the models of interactions between IL-17 and TNF, and genes expressed by activated endothelial cells. This work is devoted to mathematical modeling and numerical simulations of blood coagulation and clot growth under the influence of IL-17 and TNF-alpha. We show that they can provoke thrombosis, leading to the complete or partial occlusion of blood vessels. The regimes of blood coagulation and conditions of occlusion are investigated in numerical simulations and in approximate analytical models. The results of mathematical modeling allow us to predict thrombosis development for an individual patient. PMID- 29195856 TI - Codon usage and expression level of human mitochondrial 13 protein coding genes across six continents. AB - The study of codon usage coupled with phylogenetic analysis is an important tool to understand the genetic and evolutionary relationship of a gene. The 13 protein coding genes of human mitochondria are involved in electron transport chain for the generation of energy currency (ATP). However, no work has yet been reported on the codon usage of the mitochondrial protein coding genes across six continents. To understand the patterns of codon usage in mitochondrial genes across six different continents, we used bioinformatic analyses to analyze the protein coding genes. The codon usage bias was low as revealed from high ENC value. Correlation between codon usage and GC3 suggested that all the codons ending with G/C were positively correlated with GC3 but vice versa for A/T ending codons with the exception of ND4L and ND5 genes. Neutrality plot revealed that for the genes ATP6, COI, COIII, CYB, ND4 and ND4L, natural selection might have played a major role while mutation pressure might have played a dominant role in the codon usage bias of ATP8, COII, ND1, ND2, ND3, ND5 and ND6 genes. Phylogenetic analysis indicated that evolutionary relationships in each of 13 protein coding genes of human mitochondria were different across six continents and further suggested that geographical distance was an important factor for the origin and evolution of 13 protein coding genes of human mitochondria. PMID- 29195857 TI - Evaluating acarological risk for exposure to Ixodes scapularis and Ixodes scapularis-borne pathogens in recreational and residential settings in Washington County, Minnesota. AB - The distribution of I. scapularis, the tick vector of the bacteria that cause Lyme disease, has been expanding over the last two decades in the north-central United States in parallel with increasing incidence of human cases of Lyme disease in that region. However, assessments of residential risk for exposure to ticks are lacking from this region. Here, we measured the density of host-seeking I. scapularis nymphs in two suburban and two rural public recreational sites located in Washington County, Minnesota as well as in nearby residential properties. We sought to compare tick densities across land use types and to identify environmental factors that might impact nymphal density. We also assessed the prevalence of infection in the collected ticks with Lyme disease spirochetes (Borrelia burgdorferi sensu stricto, B. mayonii), and other I. scapularis-borne pathogens including B. miyamotoi, Babesia microti and Anaplasma phagocytophilum. Similar to studies from the eastern United States, on residential properties, I. scapularis nymphal densities were highest in the ecotonal areas between the forest edge and the lawn. Residences with the highest densities of nymphs were more likely to have a higher percentage of forest cover, log piles, and signs of deer on their property. In recreational areas, we found the highest nymphal densities both in the wooded areas next to trails as well as on mowed trails. Among the 303 host-seeking I. scapularis nymphs tested for pathogens, B. burgdorferi sensu stricto, A. phagocytophilum and B. miyamotoi were detected in 42 (13.8%), 14 (4.6%), and 2 (0.6%) nymphs, respectively. PMID- 29195858 TI - Phosphate-Binder Use in US Dialysis Patients: Prevalence, Costs, Evidence, and Policies. AB - Medicare costs for phosphate binders for US dialysis patients and patients with chronic kidney disease enrolled in Medicare Part D exceeded $1.5 billion in 2015. Previous data have shown that Part D costs for mineral and bone disorder medications increased faster than costs for all Part D medications for dialysis patients. Despite extensive use of phosphate binders and escalating costs, conclusive evidence is lacking that they improve important clinical end points in dialysis patients or non-dialysis-dependent patients with chronic kidney disease. Using dialysis patient data from the US Renal Data System and laboratory information from the Centers for Medicare & Medicaid Services (CMS) CROWNWeb data, we update information on trends in phosphate-binder use, calcium and phosphorus values, and costs for Medicare-covered dialysis patients. We discuss these results in the context of evidence from clinical trials, meta-analyses, and observational studies evaluating phosphate-binder efficacy, safety, comparative effectiveness, and cost-effectiveness. Based on our analysis, we note a need for US Food and Drug Administration guidance regarding clinical evaluation of new phosphate binders, and we suggest that it would be in CMS' best interest to fund a clinical trial to assess whether lower versus higher phosphate concentrations improve hard clinical outcomes, and if so, whether particular phosphate binders are superior to placebo or other binders in improving these outcomes.

Cell staining with X-gal is a common procedure to detect senescent cells in culture. However, the organelle nature of the staining makes automatic count impossible, requiring time-consuming manual counting or expensive alternative techniques such as flow cytometry to effectively determine the amount of stained cells. Here we present an analysis strategy for images of X-gal stained cells which can be implemented into a macro for the ImageJ software overcoming some of the drawbacks of computational analysis of organelle staining.

PMID- 29195861 TI - The effect of Cytochalasin B and Jasplakinolide on depolymerization of actin filaments in goose muscles during postmortem conditioning. AB - Breast muscles of twenty-four Eastern Zhejiang White Geese were randomly divided into three groups: control, Cytochalasin B (Cyt B) and Jasplakinolide (Jasp) treatments during postmortem conditioning. The myofibrillar fraction index (MFI), actin filaments and the levels of F-actin, G-actin and actin associated proteins (cofilins and tropomodulins) during conditioning were investigated. In control, the degraded tropomodulins, increased G-actin and disrupted actin filaments were observed at 4 and 7days; the increase of MFI and decrease of F-actin content were shown during conditioning. Cyt B treatments accelerated the transformation from F actin to G-actin, weakened actin filaments and increased MFI compared to the control, while Jasp gained the opposite effect against Cyt B. We concluded that depolymerization of actin filaments regulated by tropomodulins contributed to myofibrillar fraction during conditioning. This work provided a new pathway of tenderization by the depolymerization of actin filaments. PMID- 29195862 TI - Spray-dried extract from the Amazonian adaptogenic plant Ampelozizyphus amazonicus Ducke (Saracura-mira): Chemical composition and immunomodulatory properties. AB - Ampelozizyphus amazonicus Ducke is a medicinal plant used in the Amazon region to prepare a drink with tonic, immunomodulatory and adaptogenic properties. Due to the growing interest in dietary supplements with these properties and, to provide a new functional ingredient, barks from A. amazonicus were extracted. The extract was spray dried without drying adjuvants, resulting in a powder (SARF), which was characterized by its physico-chemical properties and proximate, mineral and saponin contents. The SARF saponins were characterized by ultra-high-performance liquid chromatography/high resolution accurate mass spectrometry (HPLC-HRMSn) analysis. The SARF particles tended to have a spherical shape and a unimodal size distribution. The particles also had good rehydration characteristics and high saponin content (33%). The effect of SARF on antibody production was investigated, and we found that SARF increased the basal levels of anti ovalbumin, anti-LPS and anti-dextran IgM antibodies, and the anti-dextran IgG antibodies in unimmunized mice. No increase in antibody titers was observed after SARF treatment in immunized mice. These results suggest that SARF could be an interesting new functional ingredient for food applications or pharmaceutical products. PMID- 29195863 TI - An investigation into the structure, morphology and thermal properties of amylomaize starch-fatty acid complexes prepared at different temperatures. AB - Amylomaize (Hylon VII) starch-fatty acid (capric, myristic, palmitic, stearic, oleic) complexes prepared at 30, 50 or 70 degrees C were studied using XRD, DSC, SEM, TGA and FTIR techniques. XRD diffractograms displayed the typical V-form of complexed amylose regardless the temperature of preparing the complexes. The degree of crystallinity of the complexes increased while the size of the crystals formed decreased as the preparation temperature of the complexes increased. DSC thermograms showed that the dissociation temperature of the complexes was increased proportionally to the chain length increase of the fatty acid. TGA indicated that oleic acid was adequately protected in the form of complexes. SEM micrographs showed the presence of crystals of the complexes either in the form of spherulites or in the form of lamellae. Enzymatic hydrolysis of the complexes led to quantitative recovery of the guest molecules. Hylon VII proved to be a suitable prospective complexing agent for the production of complexes of lipids. PMID- 29195864 TI - Development of an immobilization system for in situ micronutrients release. AB - An immobilization system constituted by coated microcapsules was developed aiming at immobilizing probiotic bacteria capable of producing folate and release it in a sustained manner into the intestine. Despite no probiotic folate-producers have been immobilized so far, the system has been developed with this goal and this work reports its stability and ability to release folate under gastro-intestinal conditions. Microcapsules were made of alginate with three consecutive coatings of poly-l-lysine, sodium alginate and chitosan. Turbidity experiments showed a strong electrostatic interaction between these polymers. Fourier transform infrared spectroscopy (FTIR) and confocal analysis showed the stability of the coating materials when applied on the microcapsules, even after they were immersed in solutions simulating conditions in the stomach and small intestine (i.e. pH2, 60min and pH7.2, 120min, respectively). Coated microcapsules have an average diameter size ranged from 20 and 40MUm, and swelled upon exposure to a neutral medium, without dissolution as showed by microscopy analyses. Release experiments proved the ability of the coated microcapsules to release folic acid, at different rates, depending on the applied coating. Release experiments showed that the first coating (E-PLL) is characterized by Fickian diffusion as the main release mechanism of folic acid. Fickian rate constant (kF) decreased with the number of consequent coatings, reflecting the decrease of predominance of Fick's behavior. Results showed that the developed coated microcapsules have suitable characteristics for encapsulation of folic acid aiming in situ release in the intestine. PMID- 29195865 TI - Differentiation of cocoa nibs from distinct origins using comprehensive two dimensional gas chromatography and multivariate analysis. AB - Headspace solid-phase microextraction (HS-SPME) combined with comprehensive two dimensional gas chromatography was used for identification of volatiles compounds responsible for differentiation between cocoa nibs from Brazil and Ivory Coast. The unfolded GC*GC with Flame Ionization Detector (FID) chromatograms were first aligned using the correlation optimization warping (COW) algorithm and normalized. After that, Fisher ratio was calculated for each variable, and a threshold value was chosen to select the variables that best promote a separation of nibs samples from different sources in a principal component analysis (PCA) model. To identify the relevant compounds for the separation, representative samples of each source were analyzed in the same conditions by GC*GC with detection by quadrupole mass spectrometry. Finally, the average peak volumes for each key compound obtained for both classes were compared using a Student t-test and it was possible to identify 15 volatile compounds responsible for differentiation between cocoa nibs from Brazil and Ivory Coast. PMID- 29195866 TI - beta-Carotene-loaded nanostructured lipid carriers produced by solvent displacement method. AB - Tristearin solid lipid nanoparticles and tristearin/high oleic sunflower oil nanostructured lipid carriers were produced by solvent displacement method. All conditions allowed forming polydisperse particles within nanometric range and the presence of high oleic sunflower oil did not affect the particles mean size. Nevertheless, incorporation of beta-carotene reduced the particles polydispersity. Thermograms of solid lipid nanoparticles and nanostructured lipid carriers showed that sunflower oil generated a crystal order disturbance, since nanoparticles with less-organized lipid matrix were produced. Nanostructured lipid carriers exhibited an improvement of beta-carotene loading capacity when compared with solid lipid nanoparticles, which enhanced with the increasing of high oleic sunflower oil content. Although total beta-carotene degradation was similar for all systems, color analysis showed that the degradation of encapsulated beta-carotene was lower for high sunflower oil content. Nanostructured lipid carriers exhibited advantages over the solid lipid nanoparticles, such as enhanced drug loading capacity and prevention of drug expulsion, which makes this a versatile delivery system for food applications. PMID- 29195867 TI - Lactococcus lactis subsp. cremoris strain JFR1 attenuates Salmonella adhesion to human intestinal cells in vitro. AB - Lactococcus lactis subsp. cremoris JFR1 has been studied in reduced fat cheese due to its ability to produce exopolysaccharides (EPS) in situ, contributing to improved textural and organoleptic properties. In this study, the effect of strain JFR1 on virulence gene expression and attachment of Salmonella to HT-29 human colon carcinoma cells was investigated. Overnight cultures of L. lactis subsp. cremoris JFR1 containing EPS, grown in M17 media with 0.5% glucose supplementation, decreased attachment as well as down regulated virulence gene expression in Salmonella enterica subsp. enterica when tested on HT-29 cells. However, EPS isolated from milk fermented with L. lactis subsp. cremoris JFR1 did not affect Salmonella virulence gene expression or attachment to HT-29 cells. These results suggest that EPS does not contribute to the attachment of Salmonella to human intestinal cells. However, the possibility that the isolation process may have affected the structural features of EPS cannot be ruled out. PMID- 29195868 TI - Mitigation strategies of acrylamide, furans, heterocyclic amines and browning during the Maillard reaction in foods. AB - The Maillard reaction (MR) occurs widely during food manufacture and storage, through controlled or uncontrolled pathways. Its consequences are ambiguous depending on the nature and processing of the food products. The MR is often used by food manufacturer to develop appealing aromas, colour or texture in food products (cereal based food, coffee, meat...). However, despite some positive aspects, the MR could decrease the nutritional value of food, generate potentially harmful compounds (e.g. acrylamide, furans, heterocyclic amines) or modify aroma or colour although it is not desired (milk, fruit juice). This paper presents a review of the different solutions available to control or moderate the MR in various food products from preventive to removal methods. A brief reminder of the role and influence of the MR on food quality and safety is also provided. PMID- 29195869 TI - Lactoferrin-based nanoparticles as a vehicle for iron in food applications - Development and release profile. AB - This study aims at developing and characterizing bovine lactoferrin (bLf) nanoparticles as an iron carrier. bLf nanoparticles were characterized in terms of size, polydispersity index (PdI), electric charge (zeta-potential), morphology, structure and stability over time. Subsequently, iron release experiments were performed at different pH values (2.0 and 7.0) at 37 degrees C, in order to understand the release mechanism. bLf (0.2%, w/v) nanoparticles were successfully produced by thermal gelation (75 degrees C for 20min). bLf nanoparticles with 35mM FeCl3 showed an iron binding efficiency value of approximately 20%. The nanoparticles were stable (i.e. no significant variation of size and PdI of the nanoparticles) for 76days at 4 degrees C and showed to be stable between 4 and 60 degrees C and pH2 and 11. Release experiments at pH2 showed that iron release could be described by the linear superposition model (explained by Fick and relaxation phenomenon). On the contrary, the release mechanism at pH7 cannot be described by either Fick or polymer relaxation behaviour. In general, results suggested that bLf nanoparticles could be used as an iron delivery system for future food applications. PMID- 29195870 TI - Influence of reuterin-producing Lactobacillus reuteri coupled with glycerol on biochemical, physical and sensory properties of semi-hard ewe milk cheese. AB - The biochemical, physical and sensory characteristics of ewe milk cheeses made with reuterin-producing Lactobacillus reuteri and glycerol (substrate for reuterin production) were assessed. Cheese made with lactococci starter (CTRL), cheese made with starter and L. reuteri (SLR), and cheese made with starter, L. reuteri and 30mM glycerol (SLR-G) were manufactured. L. reuteri reached counts above 7logcfu/g on day 1. Lactococci survival was enhanced in SLR cheese without affecting cheese pH, dry matter, proteolysis, concentration of most free amino acids (FAA), textural and most color parameters, or sensory characteristics. In situ production of reuterin by L. reuteri was only detected in SLR-G cheese, decreasing LAB counts although acidification remained unaffected. SLR-G cheese showed higher values of cell free aminopeptidase activity, overall proteolysis and FAA, particularly glutamic acid, than CTRL and SLR cheeses. The addition of L. reuteri-glycerol resulted in lower hardness and elasticity values in SLR-G cheese and influenced its L*, a* and b* color parameters. However, these changes, which were detected by instrumental analysis, did not affect the sensory scores for texture and color quality of SLR-G cheese, and it received the highest scores for taste quality. Our results suggest that L. reuteri-glycerol may provide a suitable system to release the antimicrobial reuterin in cheese without affecting negatively its sensory characteristics. PMID- 29195871 TI - 3-Chlorotyrosine formation in ready-to-eat vegetables due to hypochlorite treatment and its dietary exposure and risk assessment. AB - Washing of iceberg lettuce with HOCl solutions in concentrations ranging from 1.41 to 141mg/L resulted in 0.69 to 2.05MUg3-chlorotyrosine/g vegetable. As also six commercial ready-to-eat iceberg lettuces from different producers contained 3 chlorotyrosine from 1.00 to 2.24MUg/g vegetable, a total of 122 ready-to-eat vegetable samples purchased in Belgian supermarkets were further screened for their 3-chlorotyrosine content. 3-chlorotyrosine was detected above the detection limit (0.19MUg/g sample) in 97, 24 and 14% of the lettuce mixes, vegetable mixes and frozen vegetables, respectively. In combination with consumption data of ready-to-eat vegetables by Belgian and Spanish consumers, a quantitative exposure assessment was performed, exemplifying a lower and higher ready-to-eat vegetables consuming population. Exposure to 3-chlorotyrosine from the frozen vegetables and vegetable mixes was lower compared to the lettuce mixes due to the combination of lower contamination and lower consumption. 3-chlorotyrosine exposure via lettuce mixes could be considered as a public health concern, especially in higher consuming populations represented by the Spanish population, with 17% of consumers (>4.2 million people) and 8.5% of the total population (>2,6 million people) exceeding the threshold of toxicological concern. PMID- 29195872 TI - Multivariate analyses of a wide selection of orange varieties based on carotenoid contents, color and in vitro antioxidant capacity. AB - Carotenoids, color and in vitro antioxidant capacity were analyzed in twenty-two genotypes of oranges produced in Spain in two consecutive seasons. The colorless carotenoids phytoene and phytofluene were also analyzed. An important influence of the genotype on the carotenoid profile was observed. In most genotypes, such profile was characterized by the predominance of xanthophylls (82.7-93.0%), except in Cara Cara, with a higher proportion of carotenes (around 70.0%). beta cryptoxanthin was the predominant carotenoid in Rohde late and Ambersweet. The samples with the lowest carotenoid contents were the ones exhibiting the lowest Trolox Equivalent Antioxidant Capacity (TEAC) and vice versa. A formula obtained by multiple regression is proposed to estimate the TEAC value from the carotenoid content. No significant correlation between TEAC values and color coordinates were obtained, suggesting that color parameters are not good predictors of TEAC values. Lastly, the samples could be classify with a high rate of success (>90%) by Linear Discriminant Analysis based on color and carotenoids.

AB - Soybean contains several biologically active components and one of this belongs to the bioactive peptide group. The objectives of this study were to produce different lunasin-enriched preparations (LEP) and determine the effect of Bowman Birk inhibitor (BBI) and Kunitz trypsin inhibitor (KTI) concentrations on the stability of lunasin against pepsin-pancreatin hydrolysis (PPH). In addition, the effect of KTI mutation on lunasin stability against PPH was determined. LEP were produced by calcium and pH precipitation methods of 30% aqueous ethanol extract from defatted soybean flour. LEP, lunasin-enriched commercially available products and KTI control and mutant flours underwent PPH and samples were taken after pepsin and pepsin-pancreatin hydrolysis. The concentrations of BBI, KTI, and lunasin all decreased after hydrolysis, but they had varying results. BBI concentration ranged from 167.5 to 655.8MUg/g pre-hydrolysis and 171.5 to 250.1MUg/g after hydrolysis. KTI concentrations ranged from 0.3 to 122.3MUg/g pre hydrolysis and 9.0 to 18.7MUg/g after hydrolysis. Lunasin concentrations ranged from 8.5 to 71.0MUg/g pre-hydrolysis and 4.0 to 13.2MUg/g after hydrolysis. In all products tested, lunasin concentration after PPH significantly correlated with BBI and KTI concentrations. Mutation in two KTI isoforms led to a lower concentration of lunasin after PPH. This is the first report on the potential role of KTI in lunasin stability against PPH and must be considered in designing lunasin-enriched products that could potentially survive digestion after oral ingestion. PMID- 29195874 TI - Development of an in vitro mechanical gastric system (IMGS) with realistic peristalsis to assess lipid digestibility. AB - A new in vitro mechanical gastric system (IMGS) was fabricated which incorporates: a J-shaped stomach, a mechanical system with realistic peristaltic frequency and force magnitude, and a reproduction of the gastric pH curve. To evaluate the impact of a more realistic gastric peristalsis on the intestinal lipolysis of protein-stabilized O/W emulsions, the emulsions were subjected to two different in vitro digestion methodologies: (i) gastric digestion in the IMGS and intestinal digestion in a stirred beaker (SB), and (ii) gastric and intestinal digestion assays carried out in SBs. At the end of the intestinal digestion, the total amount of free fatty acids released was significantly higher for the first methodology (IMGS-SB) in comparison with the second one (27.5% vs. 23.0%), probably due to the higher physical instability induced by the IMGS in the gastric contents. These results reaffirm that O/W emulsion stability plays a crucial role in controlling the final extent of lipolysis of this kind of food grade emulsions. PMID- 29195876 TI - Front of package symbols as a tool to promote healthier food choices in Slovenia: Accompanying explanatory claim can considerably influence the consumer's preferences. AB - Many nutrition and/or health symbols were introduced in different countries in the past years and Slovenia is no exception. The objective of our study was to examine familiarity with and perception of the Protective Food symbol (PF symbol) in Slovenia and to investigate consumers' associations related to the symbol, and the influence of symbols' appearance on their preferences. The study was conducted through online questionnaire with incorporated word-association tasks and conjoint analysis; GfK consumer panel and social media (Facebook) were used for recruitment of Slovenian adults (n=1050; 534 men, 516 women). The majority (78%) of the participants reported they had previously seen the PF symbol, and 64% declared familiarity with it. Familiarity was verified using a word association task in which we analysed the nature of the symbol's description, distinguishing the description of symbol's visual appearance or its meaning. In this task, 73% of the participants described the symbol's meaning with reference to health or a healthy lifestyle, confirming their familiarity with it. Women and those responsible for grocery shopping were significantly more familiar with the symbol. The impact of the symbol's appearance on consumers' preferences was investigated using conjoint analysis consisting of two attributes - three different symbols found on foods in Slovenia (PF symbol, Choices Programme symbol and Keyhole symbol), and accompanying worded claims. Although worded claims had less relative importance (29.5%) than the symbols (70.5%), we show that careful choice of the wording can affect consumers' preferences considerably. The lowest part-worth utility was observed without an accompanying claim, and the highest for the claim directly communicating health ("Protects your health"). The fact that most participants are well familiar with the PF symbol indicates the symbol's potential to promote healthier food choices, which could be further improved by an accompanying worded claim that clearly describes its meaning. In addition, the use of Facebook ads is shown to be a useful alternative recruitment method for research with consumers. PMID- 29195875 TI - Exploring the protective effects of calcium-containing carrier against drying induced cellular injuries of probiotics using single droplet drying technique. AB - Protective carriers that encapsulate probiotics in spray drying could improve the survival ratio of dried cells through different mechanisms. Unveiling the protective mechanism of each carrier will contribute to a rational design of high performance carrier formulation. This study utilized single droplet drying (SDD) technique to investigate the effects of calcium cation in varied carrier formulation. Inactivation histories of Lactobacillus rhamnosus GG (LGG) in different carriers were compared, and cellular injury history of probiotics during droplet drying was studied for the first time. Adding 1mM CaCl2 to lactose carrier protected cell viability, mitigated cellular injuries, and enhanced regrowth capability as drying progressed, demonstrating the positive effect of Ca2+ with possible mechanism of stabilizing sub-cellular structures. At later drying stages, cell survival in Lac/Ca carrier was increased by 0.5-1.5 log on selective media compared to lactose carrier. Supplementing calcium-binding agents lowered the protective effect, shortening the initiation of rapid cell inactivation down to 120s of drying. Adding CaCl2 to trehalose carrier barely improved cell survival, indicating that the protective effect could be influenced by carrier formulation. Pure trehalose carrier exerted excellent protection on LGG, supporting cells to regrow in liquid rich medium even after 180s of drying. The protection of trehalose may stem from stabilization of sub-cellular structures, which possibly overlap the effect of Ca2+. The findings suggested that high performance carrier formulation might be developed by combining carrier materials with different protective mechanisms, for maximizing the survival of active dry probiotics in industrial spray drying operation. PMID- 29195877 TI - Does a time constraint modify results from rating-based conjoint analysis? Case study with orange/pomegranate juice bottles. AB - People do not usually process all the available information on packages for making their food choices and rely on heuristics for making their decisions, particularly when having limited time. However, in most consumer studies encourage participants to invest a lot of time for making their choices. Therefore, imposing a time-constraint in consumer studies may increase their ecological validity. In this context, the aim of the present work was to evaluate the influence of a time-constraint on consumer evaluation of pomegranate/orange juice bottles using rating-based conjoint task. A consumer study with 100 participants was carried out, in which they had to evaluate 16 pomegranate/orange fruit juice bottles, differing in bottle design, front-of-pack nutritional information, nutrition claim and processing claim, and to rate their intention to purchase. Half of the participants evaluated the bottle images without time constraint and the other half had a time-constraint of 3s for evaluating each image. Eye-movements were recorded during the evaluation. Results showed that time-constraint when evaluating intention to purchase did not largely modify the way in which consumers visually processed bottle images. Regardless of the experimental condition (with or without time constraint), they tended to evaluate the same product characteristics and to give them the same relative importance. However, a trend towards a more superficial evaluation of the bottles that skipped complex information was observed. Regarding the influence of product characteristics on consumer intention to purchase, bottle design was the variable with the largest relative importance in both conditions, overriding the influence of nutritional or processing characteristics, which stresses the importance of graphic design in shaping consumer perception. PMID- 29195878 TI - Probiotic-loaded microcapsule system for human in situ folate production: Encapsulation and system validation. AB - This study focused on the use of a new system, an alginate|E-poly-l lysine|alginate|chitosan microcapsule (APACM), able to immobilize a folate producing probiotic, Lactococcus lactis ssp. cremoris (LLC), which provides a new approach to the utilization of capsules and probiotics for in situ production of vitamins. LLC is able to produce 95.25+/-26MUg.L-1 of folate, during 10h, and was encapsulated in the APACM. APACM proved its capacity to protect LLC against the harsh conditions of a simulated digestion maintaining a viable concentration of 6logCFU.mL-1of LLC. A nutrients exchange capacity test, was performed using Lactobacillus plantarum UM7, a high lactic acid producer was used here to avoid false negative results. The production and release of 2g.L-1 of lactic acid was achieved through encapsulation of L. plantarum, after 20h. The adhesion of APACM to epithelial cells was also quantified, yielding 38% and 33% of capsules adhered to HT-29 cells and Caco-2 cells, respectively. PMID- 29195879 TI - Role of mono- and oligosaccharides from FOS as stabilizing agents during freeze drying and storage of Lactobacillus delbrueckii subsp. bulgaricus. AB - The aim of this work was to assess the role of mono- and oligosaccharides present in fructo-oligosaccharides (FOS) mixtures as protective agents during freeze drying and storage of Lactobacillus delbrueckii subsp. bulgaricus CIDCA 333. Different FOS mixtures were enzymatically obtained from sucrose and further purified by removing the monosaccharides produced as secondary products. Their glass transition temperatures (Tg) were determined at 11, 22 and 33% relative humidity (RH). Bacterial cultures were freeze-dried in the presence of 20% w/v solutions of the studied FOS. Their protective effect during freeze-drying was assessed by bacterial plate counting, and by determining the lag time from growth kinetics and the uptake of propidium iodide (PI). Plate counting during bacterial storage at 4 degrees C, and 11, 22 and 33% RH for 80days completed this rational analysis of the protective effect of FOS. Purification of FOS led to an increase of Tg in all the conditions assayed. Microorganisms freeze-dried in the presence of non-purified FOS were those with the shortest lag times. Bacteria freeze-dried with pure or commercial FOS (92% of total FOS) showed larger lag times (8.9 12.6h). The cultivability of microorganisms freeze-dried with non-purified FOS and with sucrose was not significantly different from that of bacteria before freeze-drying (8.74+/-0.14logCFU/mL). Pure or commercial FOS were less efficient in protecting bacteria during freeze-drying. All the protectants prevented membrane damage. The cultivability of bacteria freeze-dried with FOS decayed <1logarithmicunit after 80days of storage at 11% RH. When storing at 22 and 33% RH, pure and commercial FOS were those that best protected bacteria, and FOS containing monosaccharides were less efficient. The effect of FOS on bacterial protection is the result of a balance between monosaccharides, sucrose and larger FOS in the mixtures: the smallest sugars are more efficient in protecting lipid membranes, and the larger ones favor the formation of vitreous states. PMID- 29195880 TI - Technological, rheological and sensory characterizations of a yogurt containing an exopolysaccharide extract from Lactobacillus fermentum Lf2, a new food additive. AB - Lactobacillus fermentum Lf2, an autochthonous strain isolated as a non starter culture in Cremoso cheese, produces high EPS levels (~1g/L) in optimized conditions (SDM broth, pH6.0, 30 degrees C, 72h). Technological (texture profile and rheological analysis) and sensory properties of non-fat yogurts with 300 and 600mg EPS/L were studied at 3 and 25days after manufacture. Yogurts with different EPS concentrations showed higher hardness values than the control group at both periods of time, being the only significant difference that remained stable during time. The consistency index was also higher for the treated samples at both times evaluated, being significantly different for samples with 300mg/L of EPS extract, while the flow behavior index was lower for EPS-added yogurts. The thixotropic index was lower (P<0.05) for samples with the highest EPS extract concentration at the end of the storage time. Regarding the sensory analysis, those yogurts with 600mg/L of EPS extract presented the highest values of consistency at 3days of storage. No considerable differences for defects (milk powder, acid, bitter and cooked milk flavors) were perceived between treated and control samples at both times evaluated. Syneresis was also studied and samples with 600mg/L of EPS extract presented the lowest syneresis values at 25days of storage, which considerably decreased with the time of storage. In conclusion, the EPS from L. fermentum Lf2, used as an additive, provided yogurt with creamy consistency and increased hardness, without the presence of unwanted defects and improving the water holding capacity of the product. All the analysis done showed the potential of this extract to be used as a technofunctional natural ingredient, and it should be considered its positive impact on health, according to previous studies. PMID- 29195881 TI - Identification, characterization, and initial epitope mapping of pine nut allergen Pin k 2. AB - The aims of this study were to predict, identify and characterize pine nut allergens. Korean pine (Pinus koraiensis) vicilin was predicted to be a pine nut allergen. Recombinant Korean pine vicilin was expressed in E. coli and purified. Natural Korean pine vicilin isolated from pine nuts (which displayed multiple bands in SDS-gels due to posttranslational digestion) and its full length recombinant counterpart were used to test whether it is a food allergen. The recognition of the protein (and its fragments) by patient serum IgE was analyzed by Western blot. The study included fourteen patients diagnosed with clinical pine nut allergy. Twenty nine percent of the patient sera recognized both the natural and recombinant pine nut vicilin, indicating that Korean pine vicilin is a bona fide food allergen. The serum recognition patterns of the naturally occurring protein fragments suggested that some of linear IgE epitopes may be mapped to the fragment boundaries. The chemical and thermal stability of the recombinant protein was investigated. It underwent a thermal transition with a Tm=76.6 degrees C. The transition was accompanied by an increase in the amplitude of the circular dichroism signal at 220nm. Urea induced unfolding of the recombinant protein had a Cm of 4.6M. PMID- 29195882 TI - Assessment of antioxidant activity, lipid profile, general biochemical and immune system responses of Wistar rats fed with dairy dessert containing Lactobacillus acidophilus La-5. AB - The viability and survival of Lactobacillus acidophilus La5 under in vitro simulated gastrointestinal in probiotic dairy dessert was assessed. In addition, the effects of regular consumption of the dessert (5g/day) on the lipid profile, immune system, and antioxidant/biochemical status of Wistar rats were also evaluated after 2weeks of treatment. Adequate counts of L. acidophilus La-5 were observed regards the viability and gastrointestinal conditions. The probiotic dairy dessert was efficient in reducing the LDL-cholesterol, triacylglycerol and increased the HDL-cholesterol in serum. Aspartate amino transferase, alanine aminotransferase, total protein, albumin, heat shock proteins, immune system responses, and blood-cells counts (monocyte, lymphocyte, neutrophil and leucocyte) were not affected (p>0.05) after 15days of treatment. Overall, the probiotic dairy dessert may be a viable alternative to enhance the blood lipid profile and could be used to improve the antioxidant defenses. PMID- 29195883 TI - Metabolic profile comparison of fruit juice from certified sweet cherry trees (Prunus avium L.) of Ferrovia and Giorgia cultivars: A preliminary study. AB - Sweet cherries are widely appreciated for fresh consumption as well as for production of juices, jams, jelly fruits and alcoholic beverages. The sweet cherry intake (as fresh fruit and related products) is extensively encouraged for their taste and nutritional qualities, due to the presence of water-soluble (C, B) and fat-soluble (A, E and K) vitamins, carotenoids, polyphenols and minerals, as well as glucose and fructose. However the market often endorses the consumption of a particular sweet cherry cultivar (as for most of vegetables) essentially for organoleptic and/or external appearance rather than nutraceutical qualities. In order to evaluate the potential difference in the nutritional quality of fruits, 56 sweet cherry juice samples from certified trees (Prunus avium L.) of two cultivars (30 from Ferrovia and 26 from Giorgia), grown in the same pedoclimatic Apulian region, were analyzed by 1H NMR spectroscopy and Multivariate Analysis (MVA). Interestingly, despite the usually lower commercial value with respect to the Ferrovia, Giorgia cultivar shows higher content of malic acid and phenolic compounds with important well known nutraceutical properties such as antioxidant activity and stimulating metabolism. PMID- 29195884 TI - Study of the polysemic term of minerality in wine: Segmentation of consumers based on their textual responses to an open-ended survey. AB - Over the past 20years, the word "minerality" has been increasingly used in the description of wines. However, a precise definition of the concept of minerality appears to be inexistent, and no consensual meaning, even among wine professionals, can be identified. Although this word usage seems to spread out from wine professionals to consumers, research on what consumers assume about minerality is scarce. This paper aims to study the various concepts about minerality held by consumers by using an open-ended questionnaire. A total of 1697 French-speaking consumers responded to an online survey and their free answers were analysed using statistical textual methods. The clustering around latent variables (CLV) method was used, taking into account both the lexicon used and the personal characteristics of consumers to classify them. Word associativities were then computed by means of renormalized Markov associativities, generating textual networks associated to each group, as well as to personal characteristics of the consumers. Typically, the most inexperienced consumers confess to have never heard about minerality in wine. Then, young women, also endowed with little wine competences, mainly associate minerality to mineral ions as those found in bottled water. Slightly older consumers embed the concept of minerality into the idea of terroir. Finally, the most experienced consumers refer to sensory perceptions such as gunflint or acidity. Those findings are consistent with a lexical innovation process, diffusing from wine professionals to consumers, referring to the mineral kingdom (as opposed to animal or vegetal), and aiming to stress that the style of their wines has changed towards more subtlety. Beyond the specific minerality issue investigated in this paper, the methodology (CLV approach used in conjunction with renormalized Markov associativities) demonstrates its ability to generate informative clusters of textual networks, highlighting the cores of prototypical sentences, and apt to investigate the meaning of new concepts. PMID- 29195885 TI - Differentiation of commercial ground beef products and correlation between metabolites and sensory attributes: A metabolomic approach. AB - Three traditional grinds (commodity products) and 7 non-traditional grinds (branded products) were obtained to investigate the metabolites in ground beef associated with beef flavor or off-flavor. Three packaging methods were used: traditional overwrap, modified atmosphere package, and clear plastic retail chub. Samples were collected for sensory evaluation and metabolic profiling utilizing LC/MS. Principal component analysis was conducted for classification of grind source or packaging method. Partial least squares regression was applied to investigate the relationship between metabolic data and sensory data. Grass-fed beef and natural beef products were clearly separated from the other grinds. A total of 576 metabolites were registered. Thirty-three compounds were selected as the most important ones differentiating beef grinds. Twenty-two compounds were selected as the most important ones associated with beef flavor and off-flavor. In conclusion, metabolomic approach was effective to determine the most important compounds associated with certain quality characteristics of beef. PMID- 29195886 TI - LC-MSn study of the chemical transformations of hydroxycinnamates during yerba mate (Ilex paraguariensis) tea brewing. AB - Yerba mate is one of the most popular beverages in South American countries and its consumption is associated with a wide array of health effects. In this study, we used advanced HPLC-ESI-MSn and HPLC-ESI-HRMS methods for the identification and characterization of hydroxycinnamates and their derivatives formed during the brewing process of yerba mate. We report on the hydroxylation of the hydroxycinnamates cinnamoyl substituent by conjugate addition of water to form 3 hydroxy-dihydrocinnamic acid derivatives using a series of model compounds, including caffeoylglucoses, dicaffeoylquinic acids, methyl caffeoylquinate and mono caffeoylquinic acids. The regiochemistry of conjugate addition was determined by targeted tandem MS experiments performed on authentic standards. It was interesting to note that hydroxylation of hydroxycinnamates produced cis and acyl-migration isomers, which is in line with previously reported data. PMID- 29195887 TI - Antioxidant capacity of cocoa beans and chocolate assessed by FTIR. AB - The total antioxidant capacity (TAC) and total phenolic compounds (TPC) of cocoa beans and chocolate produced from spontaneous and inoculated fermentations of different cocoa varieties were evaluated. Fourier transform infrared spectroscopy (FTIR), as well as conventional methods: 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), was used to determine TAC and TPC. Chocolate showed higher (p<0.05) TPC (47.17-57.16mgGAE/g) and TAC (1.66-2.33mMTE/g and 8.86-11.35mMTE/g as measured by DPPH and ABTS, respectively) than cocoa beans (6.30-26.05mgGAE/g, 0.24-1.17mMTE/g and 1.29 4.83mMTE/g for TPC, DPPH and ABTS, respectively). Partial least square (PLS) model for infrared data showed a good calibration coefficient (R2cal>0.94), indicating that the FTIR technique represents a fast and reliable tool to evaluate TPC and TAC in cocoa beans and chocolate. PMID- 29195888 TI - Formulation and stability assessment of ergocalciferol loaded oil-in-water nanoemulsions: Insights of emulsifiers effect on stabilization mechanism. AB - In the study, we investigated the effect of emulsifiers with different stabilizing mechanisms on the formulation and stability of ergocalciferol loaded oil-in-water (O/W) emulsions. O/W emulsion stabilized by modified lecithin (ML; electrostatic stabilization), sodium caseinate (SC; electrosteric stabilization) or decaglycerol monooleate (MO-7S; steric stabilization) were formulated using high-pressure homogenization. The Sauter mean diameter (d3,2) of emulsions produced by ML, SC and MO-7S were 126+/-1, 127+/-4 and 138+/-3nm, respectively. The stability of resulting emulsions was evaluated when they exposed to different environmental stresses and during 30days of storage at 25 and 55 degrees C. Results showed that the emulsions prepared by MO-7S or ML were stable against a wide range of pH (2-8), while SC-stabilized emulsions showed instability with extensive droplet aggregation at pH4 or and 5. Only ML-stabilized emulsions showed droplet growth due to coalescence when treated at high NaCl concentration (300-500mM). In the absence of glucose, SC-stabilized O/W emulsions showed better freeze-thaw stability, in comparison to those formed with ML or MO-7S emulsifiers. The emulsion produced by ML was found to be stable to droplet aggregation at heating temperatures (80-120 degrees C) for 1h. All the O/W emulsions stored at 25 degrees C showed good physical and chemical stability. However, the chemical stability of ergocalciferol in emulsion system decreased in order of ML>MO-7S?SC during storage at 55 degrees C for a period of 30days. These findings provide valuable information for the development of nanoemulsion-based delivery system applied in food and beverage products. PMID- 29195889 TI - Intracellular ROS scavenging and antioxidant enzyme regulating capacities of corn gluten meal-derived antioxidant peptides in HepG2 cells. AB - The objective of this study was to investigate the intracellular reactive oxygen species (ROS) scavenging activities and antioxidant enzyme regulating capacities of corn gluten peptide fractions (CPFs) in HepG2 cells. A cellular antioxidant activity (CAA) assay was used to assess their antioxidant activities and revealed that both CPF1 (molecular weight <1kDa) and CPF2 (molecular weight between 1 and 3kDa) exhibited high cellular antioxidant activities with EC50 values of 2.85+/ 0.19mg/mL and 5.05+/-0.32mg/mL, respectively. Both CPFs also exhibited cytoprotective effects and intracellular ROS scavenging activities in HepG2 cells subjected to oxidative stress by oxidation with H2O2. In addition, at concentrations of 2.50mg/mL, the CPFs increased the activity levels of superoxide dismutase (SOD), catalase (CAT), and glutathione reductase (GR), as well as the total glutathione (GSH) levels in oxidized HepG2 cells (from 86.54% to 114.14% (CPF1) or 109.72% (CPF2) for SOD activity; from 71.91% to 107.64% (CPF1) or 106.50% (CPF2) for CAT activity; from 70.52% to 103.01% (CPF1) or 104.10% (CPF2) for GR activity; and from 81.39% to 114.00% (CPF1) or 108.82% (CPF2) for total GSH levels). These results suggested that both CPF1 and CPF2 exhibited positive effects on the activities of the intracellular antioxidant enzymes SOD, CAT and GR, as well as on the total GSH levels in HepG2 cells under conditions of oxidative stress. Furthermore, size exclusion gel chromatography and MALDI TOF/TOF mass spectrometry revealed that the molecular weights of the antioxidant peptides in CPF1 were between 500Da to 900Da, and a novel antioxidant peptide consisting of GLLLPH (Gly-Leu-Leu-Leu-Pro-His) was identified in CPF1. PMID- 29195890 TI - Probiotics and their potential applications in active edible films and coatings. AB - The global market for probiotics has been increasingly growing in recent years guided by the rising consumers' demand for healthy diets and wellness. This has caused food industries to develop new probiotic-containing food products as well as researchers to study specific characteristics of probiotics as well as their effects on human health. Probiotics are defined as live microorganisms that confer a health benefit to the host when administered in adequate quantities. Probiotics have been added to several food products as well as incorporated into biopolymeric matrices to develop active food packaging as an alternative method for controlling foodborne microorganisms, improving food safety, and providing health benefits. This review includes definition of probiotics, description of their effects on human health, discussion on their applications in edible biopolymeric matrices to develop active edible films and coatings, as well as the probiotics-related legislation. PMID- 29195891 TI - Biochemical fate of vicilin storage protein during fermentation and drying of cocoa beans. AB - Key cocoa-specific aroma precursors are generated during the fermentation of cocoa beans via the proteolysis of the vicilin-like globulin. Previous studies had shown that degradation of this particular 566 amino acid-long storage protein leads to three distinct subunits with different molecular masses. Although oligopeptides generated from the proteolysis of vicilin-like globulin have been studied previously, changes occurring to vicilin at different stages of fermentation have not yet been explored in detail. The aim of this study was to investigate the fate of vicilin protein from the non-fermented stage up to the dried cocoa beans. Our results showed a remarkable shift in the electrophoretic mobility of vicilin towards higher pI during the onset of fermentation. The pI shifted subunit was found susceptible to further degradation into a lower molecular-weight vicilin subunit. The observed pI shift correlated with, but did not depend on protein phosphorylation. Glycosylation of some but not all vicilin subunits occurred at different stages of the fermentation process. Peptides generated from vicilin throughout fermentation were analyzed by UHPLC-ESI-MS/MS revealing an initial increase and subsequent decrease in the diversity of peptides with an increasing degree of fermentation. We furthermore describe the rate of degradation of different vicilin subunits. The detected diversity and dynamics of vicilin peptides will help to define biochemical markers of distinct steps of the fermentation process. PMID- 29195892 TI - A consumer-based approach to salt reduction: Case study with bread. AB - In recent years high sodium intake has raised growing concern worldwide. A widespread reduction of salt concentration in processed foods has been claimed as one of the most effective strategies to achieve a short-term impact on global health. However, one of the major challenges in reducing salt in food products is its potential negative impact on consumer perception. For this reason, gradual salt reduction has been recommended. In this context, the aim of the present work was to present a consumer-based approach to salt reduction, using bread as case study. Two consumer studies with a total of 303 consumers were carried out. In the first study, four sequential difference thresholds were determined through paired-comparison tests, starting at a salt concentration of 2%. In the second study, 99 consumers performed a two-bite evaluation of their sensory and hedonic perception of five bread samples: a control bread containing 2% salt and four samples with reduced salt content according to the difference thresholds determined in the first study. Survival analysis was used to determine average difference thresholds, which ranged from 9.4% to 14.3% of the salt concentration of the control bread. Results showed that salt concentration significantly influenced consumer overall liking of the bread samples. However, large heterogeneity was found in consumer hedonic reaction towards salt reduction: two groups of consumers with different preference and hedonic sensitivity to salt reduction were found. Results from the present work confirm that cumulative series of small salt reductions may be a feasible strategy for reducing the sodium content of bread without affecting consumer hedonic perception and stress the importance of considering consumer perception in the design of gradual salt reduction programmes. PMID- 29195893 TI - Application of bacteriophages during depuration reduces the load of Salmonella Typhimurium in cockles. AB - As bivalve molluscs are filter feeder, often consumed raw or lightly cooked and are frequently cultivated in contaminated waters, they are implicated in food borne disease transmission to human. The present study investigated the potential application of bacteriophage (or phage) phSE-2, phage phSE-5 and phage cocktail phSE-2/phSE-5 to decrease the concentration of Salmonella enterica serovar Typhimurium (Salmonella Typhimurium) during the depuration of natural and artificially contaminated cockles (Cerastoderma edule). Cockles were artificially infected with 105 and 106colony-forming units (CFU)/mL of S. Typhimurium in static seawater and infected group were treated with phages at four different MOI values: 0.1, 1, 10 and 100. Depuration in static seawater at multiplicity of infection (MOI) of 0.1 with single phage suspensions of phSE-2 and phSE-5 provided the best results, as it decreased by ~1.3 and 1.7 logCFU/g, respectively, the concentration of Salmonella spp. after a 4h treatment. At a MOI of 0.1, the rate of inactivation with single phage suspensions was higher when compared with the results obtained using the phage cocktail. However, in naturally contaminated cockles treated in static seawater with single phage suspensions and phage cocktail phSE-2/phSE-5, similar decreases in cultivable bacteria concentration (~0.7-0.9 logCFU/g) were achieved after 6h of treatment. When artificially contaminated cockles were depurated with phage phSE-5 in a recirculated seawater system (mimicking industrial depuration conditions), a 0.9 and 2.0 logCFU/g reduction of Salmonella spp. was reached after 4 and 6h treatment. Once the depuration process was performed without phage, a 6h treatment was needed to obtain a 1.1 logCFU/g reduction of Salmonella spp. Results indicated that combining phage biocontrol with depuration procedures enhance bivalve microbial safety for human consumption by improving decontamination efficiency, proving that this technology can be transposed to the bivalves industry. Moreover, this approach also displays the advantage of reducing the time required for depuration and consequently its associated costs.

AB - Oenococcus oeni is the main species responsible for the malolactic fermentation (MLF) of wine due to its ability to survive in this environment. Some wine related stress factors, such as ethanol and low pH, may alter the cell redox balance of O. oeni. For the first time, the ability to uptake glutathione (GSH), an almost universal tripeptide with antioxidant properties, has been associated to the improvement of stress response in O. oeni. Despite the inability of O. oeni to synthesize GSH, this bacterium can capture it from the media. The ability of 30 O. oeni strains to uptake GSH was assessed in this study. Although all of the strains tested were able to import GSH, substantial variability among them was detected. To assess the physiological function of GSH, three strains with different GSH-import capacities were selected. Significant changes in membrane fatty acids composition were observed due to GSH addition. The most relevant was the increase of cyclopropane fatty acids in cell membrane, in both the exponential and the stationary phases. Cells grown with GSH showed an improved survival against ethanol shock (14% v/v). GSH addition also increased biomass production during the adaptation to wine stress conditions (pH4, pH3.4 and 6% ethanol). The results suggest that GSH enrichment could improve the resistance to stress to O. oeni, which could be useful for the adaptation of MLF starter cultures. PMID- 29195895 TI - Structural and rheological properties of xanthan gum/lysozyme system induced by in situ acidification. AB - Structural and rheological properties of xanthan gum/lysozyme (XG/Ly) system induced by electrostatic interaction through in situ acidification were investigated. The two biopolymers transited from co-solubility state to form soluble complexes, and finally produced tenuous network as the pH further decreased. The fluorescent images indicated that the network was cross-linked of XG chains by Ly, liking a polymerization process which resulted in the sol-gel transition by electrostatic interactions. High Ly content could accelerate the phase transition at the same pH condition, while XG played a contrary role. XG addition could enhance the thermal stability of Ly. The phase transition was also illustrated by zeta-potential at different pHs. The boundary parameters were determined to distinguish the phase transition regions. At the pH higher than pHphi, the negatively liked XG and Ly were in co-soluble state. They formed soluble complexes at the pH between pHphi and pHg, and gel was obtained with net microstructure as the pH continuously decreased (lower than pHg). The paper provides practical parameters that may be applicable in controlling the structure, texture, and stability of polysaccharide/protein system, as well as in food and medicinal application with various purposes. PMID- 29195896 TI - An itinerant sensory approach to investigate consumers' perception and acceptability at a food exhibition. AB - In a food exhibition where several producers of the same product category are present at the same time, consumers usually have the opportunity to taste several free samples of the same product type, thus they can experience and compare the sensory characteristics of each and evaluate their liking for each sample tasted. This study assessed the potential of an itinerant sensory data collection in understanding the consumers' perception and acceptance of cheese during a multiple tasting experience at a food exhibition. Subjects tasted seven samples of Parmigiano Reggiano cheese aged for different times (24 and 36months) at seven producer stands and recorded their evaluations using tablets, on which an application specifically developed for this study was installed. This evaluation situation was defined as "pseudo-natural," in opposition to the "natural" and the "naturalistic" settings. The itinerant sensory session comprised a liking test, a rate-all-that-apply (RATA) test using a just about right (JAR) scale, a food pairing test, and a questionnaire. Consumers significantly (p<0.05) discriminated the cheeses as a function of the aging time, describing with different attributes the 24months (sweetness, fresh fruit, grass, yogurt, butter flavors, elasticity, and humidity) and the 36months (saltiness, bitterness, sourness, spicy, aromatic herbs, cheese rind flavors, crumbliness, granularity, hardness, and hotness) aged products. The combined application of regression models, Penalty-Lift analysis, and decision tree models in investigating the relationships between liking and the RATA data, provided results revealing that the attributes elasticity, sweetness, humidity, fresh fruit, and butter were the main drivers of liking. Whereas, the attributes sourness, bitterness, and hardness were the main drivers of dislike. Therefore, even though no significant differences in terms of liking were observed among the tested cheeses, consumers preferred the attributes more frequently perceived in the least aged products. In conclusion, the presented itinerant sensory approach had provided meaningful information to understand the consumers' cheese perception and acceptability. In the future, it could advantageously be applied for studying food perception in other situations in which subjects naturally choose or consume several products while freely moving from one to another (e.g. self-service restaurant). PMID- 29195897 TI - An inflammatory environment containing TNFalpha favors Tet2-mutant clonal hematopoiesis. AB - Clonal hematopoiesis of aging and indeterminate potential (ARCH or CHIP), driven mainly by mutations in DNMT3A and TET2, is an emerging public health issue, affecting at least 10-15% of adults older than 65 years. CHIP is associated with increased risks of de novo and therapy-related hematological neoplasms and serves as a reservoir for leukemic relapse. CHIP is also associated with increased all cause mortality and risk of cardio-metabolic disease. The latter association may be explained, at least in part, by the effects of inactivating mutations in TET2 on progeny macrophages. We and others have shown recently that TET2-deficient macrophages are hyperinflammatory and this may exacerbate processes such as atherosclerosis. We postulated an inflammatory state associated with TET2 inactivation and/or unhealthy aging may also favor TET2-mutant hematopoietic stem and progenitor cell (HSPC) expansion. Herein, we demonstrate a clonogenic advantage for Tet2-knockout murine and TET2-mutant human HSPCs in an in vitro environment that contains the proinflammatory cytokine tumor necrosis factor alpha (TNFalpha). This phenotype emerges on chronic TNFalpha exposure and is associated with myeloid skewing and resistance to apoptosis. To our knowledge, this is the first evidence to suggest that TET2 mutations promote clonal dominance with aging by conferring TNFalpha resistance to sensitive bone marrow progenitors while also propagating such an inflammatory environment. Normalizing the immune environment may present a novel strategy to control or eradicate mutant CHIP clones. PMID- 29195898 TI - Outcomes of displaced olecranon fractures treated with the Olecranon Sled. AB - BACKGROUND: Tension-band wiring is largely considered the gold standard for fixation of displaced olecranon fractures despite high rates of hardware complications. The purpose of this study was to report the outcomes of displaced olecranon fractures treated with the Olecranon Sled. METHODS: We retrospectively reviewed all displaced olecranon fractures from 2011-2015 treated with the Olecranon Sled. Inclusion was limited to functionally independent patients with Mayo type II fractures and minimum 12-month follow-up. We assessed clinical outcomes including range of motion; Disabilities of the Arm, Shoulder and Hand score; and Mayo Elbow Performance Score. RESULTS: Twenty-two patients with a mean follow-up period of 31.8 months (range, 12-71 months) were included in the study. All patients indicated satisfactory outcomes. The mean Mayo Elbow Performance Score was 95.5 (range, 70-100), and the mean Disabilities of the Arm, Shoulder and Hand score was 3.1 (range, 0-18.3). The mean total arc of elbow flexion was 145 degrees (range, 134 degrees -158 degrees ), and the mean total arc of forearm rotation was 175 degrees (range, 160 degrees -180 degrees ). There were no hardware-related complications. The overall complication rate was 4.5% (1 of 22) as significant heterotopic ossification developed in 1 patient, requiring contracture release. CONCLUSION: The Olecranon Sled is a reliable and well tolerated implant for the treatment of olecranon fractures. This device results in excellent functional outcomes and may obviate hardware removal. PMID- 29195899 TI - Ibuprofen impairs capsulolabral healing in a rat model of anterior glenohumeral instability. AB - BACKGROUND: Failure of glenoid labrum and capsular healing after glenohumeral dislocation can lead to persistent shoulder instability. The purpose of this study was to determine the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) on the healing glenoid labrum and capsule after glenohumeral dislocation in a rat model. METHODS: Sixty-six rats had surgically induced anterior-inferior labral tears and anterior glenohumeral dislocation. Postoperatively, the animals were assigned to either normal (n = 32) or ibuprofen drinking water (n = 31). Animals were euthanized at 2 and 4 weeks postoperatively for biomechanical testing and histologic analysis. RESULTS: The maximum load increased from 2 to 4 weeks after injury in the NSAID groups but not in the control groups. At 2 weeks, the maximum load was lower in the NSAID group compared with the control group. In a matched comparison between injured and uninjured limbs, the maximum load was significantly decreased in the injured limb of the 2-week NSAID group. At 4 weeks, the NSAID group had decreased stiffness compared with the 4-week control group. CONCLUSIONS: In a new rat model of glenohumeral instability, the postinjury administration of ibuprofen resulted in decreased capsulolabral healing. A matched pair analysis of injured to uninjured limbs supported the findings of impaired healing in the NSAID-treated animals. These findings demonstrate that the use of NSAIDs after glenohumeral dislocation may impair capsulolabral healing and should be limited or avoided to optimize glenohumeral stability. PMID- 29195900 TI - Outcomes for subscapularis management techniques in shoulder arthroplasty: a systematic review. AB - BACKGROUND: This systematic review aims to synthesize published data for the most common subscapularis takedown and repair to compare outcomes in the setting of shoulder arthroplasty. METHODS: Searches of MEDLINE and Cochrane Library databases identified studies that reported clinical or radiologic outcomes for subscapularis management in the setting of shoulder arthroplasty. Comparisons included musculotendinous integrity, subscapularis testing and strength, shoulder range of motion, and functional outcome scores. RESULTS: The 14 included studies reported considerable variability in techniques, outcomes, and musculotendinous integrity. Lesser tuberosity osteotomy (LTO) demonstrated better healing rates (93.1%) than subscapularis peel (SP; 84.1%) and midsubstance tenotomy (ST; 75.7%), although not significantly different. A statistically significant increase in fatty infiltration was found after surgery across techniques, and range of motion and strength were similar. Mean rates of normal results for belly press and lift-off tests were uniformly better for LTO (79.1% and 80.7%) over ST (66.7% and 65.6%), although multiple studies showed poor correlation between subscapularis functional testing and musculotendinous integrity. Mean total Constant and Western Ontario Osteoarthritis of the Shoulder Index outcome scores were slightly better for LTO (77.6, 84.2) than for SP (71.8 and 82.7). Mean American Shoulder and Elbow Surgeons scores favored the ST group (80.8) over the SP (79.1) and LTO (73) groups. CONCLUSIONS: The data suggest no significant differences exist for postoperative musculotendinous integrity or clinical outcomes among the subscapularis management techniques in shoulder arthroplasty. Subscapularis healing and integrity appear to favor the lesser tuberosity takedown method. Additional randomized controlled comparisons with long-term follow-up are needed to more effectively compare these surgical approaches. PMID- 29195901 TI - Triptolide suppresses paraquat induced idiopathic pulmonary fibrosis by inhibiting TGFB1-dependent epithelial mesenchymal transition. AB - Idiopathic pulmonary fibrosis (IPF) and tumor are highly similar to abnormal cell proliferation that damages the body. This malignant cell evolution in a stressful environment closely resembles that of epithelial-mesenchymal transition (EMT). As a popular EMT-inducing factor, TGFbeta plays an important role in the progression of multiple diseases. However, the drugs that target TGFB1 are limited. In this study, we found that triptolide (TPL), a Chinese medicine extract, exerts an anti lung fibrosis effect by inhibiting the EMT of lung epithelial cells. In addition, triptolide directly binds to TGFbeta and subsequently increase E-cadherin expression and decrease vimentin expression. In in vivo studies, TPL improves the survival state and inhibits lung fibrosis in mice. In summary, this study revealed the potential therapeutic effect of paraquat induced TPL in lung fibrosis by regulating TGFbeta-dependent EMT progression. PMID- 29195902 TI - Indoxyl sulfate accelerates vascular smooth muscle cell calcification via microRNA-29b dependent regulation of Wnt/beta-catenin signaling. AB - Vascular calcification (VC) is a very common phenomenon in patients with chronic kidney disease(CKD) and it increases the incidence of cardiovascular disease and leads to high mortality in CKD patients. It has been reported that some microRNAs (miRs) play roles in vascular calcification as an epigenetic regulator. Indoxyl sulfate (IS) is a protein-bound uremic toxin which has been proven as one of the major risk factors of cardiovascular disease in CKD. Here we investigated whether microRNA-29b (miR-29b) is involved in IS-induced vascular calcification. We found that vascular miR-29b was down-regulated in radial arteries of patients with end stage renal disease. Consistently, IS also decreased miR-29b expression in human aortic smooth muscle cells (HASMCs) and potentiated their calcification. MiR-29b mimics significantly suppressed, while miR-29b anti-miR markedly enhanced, IS induced runt-related transcription factor 2 and osteopontin expression. The expression of Wnt7b/beta-catenin in radial arteries was higher in end stage renal disease than in control group, and IS increased Wnt7b/beta-catenin expression in HASMCs as early as 3days after stimulation. Furthermore, miR-29b mimics potently repressed Wnt7b/beta-catenin protein expression in HASMCs, whereas miR-29b anti miR increased their expression, indicating miR-29b indeed negatively regulates Wnt7b/beta-catenin signaling. Dickkopf-1 protein, the Wnt/beta-catenin signaling inhibitor, suppressed anti-miR-29b-enhanced HASMCs calcification. Our data thus indicate that miR-29b downregulation and Wnt/beta-catenin signaling activation may be the key mechanism of IS induced vascular calcification in chronic kidney disease.

PMID- 29195904 TI - Worldwide burden of cancer attributable to diabetes and high body-mass index: a comparative risk assessment. AB - BACKGROUND: Diabetes and high body-mass index (BMI) are associated with increased risk of several cancers, and are increasing in prevalence in most countries. We estimated the cancer incidence attributable to diabetes and high BMI as individual risk factors and in combination, by country and sex. METHODS: We estimated population attributable fractions for 12 cancers by age and sex for 175 countries in 2012. We defined high BMI as a BMI greater than or equal to 25 kg/m2. We used comprehensive prevalence estimates of diabetes and BMI categories in 2002, assuming a 10-year lag between exposure to diabetes or high BMI and incidence of cancer, combined with relative risks from published estimates, to quantify contribution of diabetes and high BMI to site-specific cancers, individually and combined as independent risk factors and in a conservative scenario in which we assumed full overlap of risk of diabetes and high BMI. We then used GLOBOCAN cancer incidence data to estimate the number of cancer cases attributable to the two risk factors. We also estimated the number of cancer cases in 2012 that were attributable to increases in the prevalence of diabetes and high BMI from 1980 to 2002. All analyses were done at individual country level and grouped by region for reporting. FINDINGS: We estimated that 5.6% of all incident cancers in 2012 were attributable to the combined effects of diabetes and high BMI as independent risk factors, corresponding to 792 600 new cases. 187 600 (24.5%) of 766 000 cases of liver cancer and 121 700 (38.4%) of 317 000 cases of endometrial cancer were attributable to these risk factors. In the conservative scenario, about 4.5% (626 900 new cases) of all incident cancers assessed were attributable to diabetes and high BMI combined. Individually, high BMI (544 300 cases) was responsible for twice as many cancer cases as diabetes (280 100 cases). 26.1% of diabetes-related cancers (equating to 77 000 new cases) and 31.9% of high BMI-related cancers (174 040 new cases) were attributable to increases in the prevalence of these risk factors from 1980 to 2002. INTERPRETATION: A substantial number of cancer cases are attributable to diabetes and high BMI. As the prevalence of these cancer risk factors increases, clinical and public health efforts should focus on identifying optimal preventive and screening measures for whole populations and individual patients.

PMID- 29195906 TI - Patterns and predictors of emergency department visits among older patients after breast cancer surgery: A population-based cohort study. AB - OBJECTIVES: To characterize rates, reasons for, and associated predictors for emergency department (ED) visits after breast cancer (BC) surgery. METHODS: All women over 65 years undergoing curative surgery for non-metastatic incident BC (1998-2012) were identified using Quebec's universal healthcare administrative databases. Reasons for ED visits within 45days of operation were reported. Associated factors were estimated using Cox regression. RESULTS: Of 24,463 patients, 12.8% had postoperative ED visits. Most frequent reasons were: superficial infection, noninfectious gastrointestinal, trauma or wound (other than breast), noninfectious respiratory, and breast wound disruption. Significant predictors included localized (aHR, 1.24, CI 1.04-1.49) or regional disease (aHR 1.64, CI 1.41-1.92), mastectomy (aHR 1.22, CI 1.10-1.34), each operation before definitive oncologic control (aHR 1.12, CI 1.03-1.21), lower institutional volume (aHR 1.23, CI 1.09-1.38), having 6-10 prescriptions (aHR 1.23, CI 1.15-1.31) or >10 (aHR 1.53, CI 1.33-1.77), benzodiazepine use (aHR 1.09, CI 1.01-1.18), anticoagulant use (aHR 1.29, CI 1.13-1.46), cardiovascular disease (aHR 1.15, CI 1.05-1.26), diabetes (aHR 1.11, CI 1.00-1.24), past hospitalization (aHR 1.25, CI 1.17-1.34), and lower income (aHR 1.12, CI 1.04-1.20). CONCLUSION: Identification of risk factors in older patients before BC surgery could help prevent postoperative ED visits. PMID- 29195907 TI - Presynaptic alpha2-adrenoceptor modulates glutamatergic synaptic transmission in rat nucleus accumbens in vitro. AB - The nucleus accumbens (NAc), integrating information from the prefrontal cortex and limbic structures, plays a critical role in reward and emotion regulation. Previous studies have reported that the NAc shell receives direct noradrenergic projections, and activation of alpha2-adrenoceptor (alpha2-AR) in the NAc shell decreases the fear or anxiety level of rats. However, the underlying mechanism is still little known. Intriguingly, glutamatergic neurotransmission in the NAc shell is closely related to reward and emotion. Here, using brain slice preparations and whole-cell patch clamp recordings, we examined the effect of activation of alpha2-AR on glutamatergic neurotransmission in the NAc shell. Perfusing slice with alpha2-AR selective agonist clonidine (CLON) reduced the evoked excitatory postsynaptic currents (EPSCs) on the NAc shell neurons. This inhibitory effect on AMPA-mediated glutamatergic EPSCs was blocked by the alpha2 AR selective antagonist yohimbine (YOH). Notably, CLON reduced the frequency but not the amplitude of miniature EPSCs. Furthermore, CLON decreased the first EPSC amplitude but increased the paired-pulse facilitation on the NAc shell neurons, and it did not affect postsynaptic AMPA/NMDA ratio, revealing a presynaptic mechanism of alpha2-AR-mediated inhibition on glutamatergic transmission. In addition, the modulation on glutamatergic transmission by alpha2-AR was independent of presynaptic NMDA receptor. These results suggest that noradrenergic afferent inputs may suppress glutamatergic synaptic transmission via presynaptic alpha2-AR in the NAc shell, and actively participate in rewarding and emotional processes via the NAc. PMID- 29195908 TI - Analysis of long non-coding RNA expression profiles following focal cerebral ischemia in mice. AB - Long noncoding RNAs (lncRNAs) have a variety of biological functions and play key roles in many diseases. However, the knowledge of lncRNA function during a stroke is limited. We analyzed the expression profiles of lncRNAs in the brain ischemic region of mice after a 45min middle cerebral artery occlusion (MCAO) with a 48h reperfusion. Gene ontology and pathway analysis were used to elucidate the potential functions of the differentially expressed mRNAs. A total of 255 lncRNAs (217 up-regulated and 38 down-regulated) and 894 mRNAs (870 up-regulated and 24 down-regulated) showed significantly altered expression in the ischemic brain compared to the sham controls (fold change ?>2, P?0.05). The gene ontology terms were mainly associated with neutrophil chemotaxis, positive regulation of inflammatory response, cell cycle, positive regulation of apoptotic process, and apoptotic process. The pathway analysis indicated that the mRNAs were mainly associated with inflammatory pathways. Additionally, the interactions between the differentially expressed lncRNAs and mRNAs are revealed by a dynamic lncRNA-mRNA network. Our findings provide an overview of aberrantly expressed lncRNAs in stroke and further broaden the understanding of stroke pathogenesis. PMID- 29195910 TI - Dispelling myths about connexins, pannexins and P2X7 in hypoxic-ischemic central nervous system. AB - In membrane physiology, as in other fields, myths or speculations may be repeated so often and so widely that they are perceived as facts. To some extent, this has occurred with regard to gap junctions, hemichannels, pannexin channels and P2X7 (ionotropic receptors), especially concerning the interpretation of the individual role of these channels in hypoxic-ischemic CNS since these channels may be closed by the same pharmacological blockers. Significance of existing controversial data are highlighted and contradictory views from different groups are critically discussed herein. PMID- 29195909 TI - Protective effects of gamma-mangostin on 6-OHDA-induced toxicity in SH-SY5Y cells. AB - gamma-Mangostin is a xanthone with hydroxyl groups that confer the substance-free radical scavenging effects. As opposed to the other more extensively studied mangostins, scarce research has been conducted on neuroprotective effects of gamma-mangostin on models of Parkinson's disease (PD). Therefore, this investigation aimed to elucidate its antioxidant and neuroprotective effects on 6 OHDA-induced toxicity in SH-SY5Y cells. 6-OHDA treatment, an inducer of PD pathology in vitro studies, decreased cell viability and increased the level of intracellular ROS production. Furthermore, the substance-induced the expression of phosphorylated p38 MAPK, negatively affected the Bax/Bcl-2 ratio and increased caspase-3 activity; all of which were factors that are associated with apoptosis. Pretreatment of cells with gamma-mangostin at concentrations of 0.5, 1, and 2.5MUM markedly increased cell survival and reduced the level of intracellular ROS formation as shown by DPPH radical scavenging activity of the compound. Furthermore, a significant suppression of p-p38, improved Bax/Bcl-2 ratio expression, and reduced caspase-3 activity was exhibited in the cells after gamma mangostin pretreatment. The reduction of apoptosis was further supported by the reduction of pyknotic nuclei indicated by Hoescht 33342 staining. These findings indicate that gamma-mangostin could attenuate 6-OHDA-induced neuronal cell death and that the protective effect of gamma-mangostin is associated with its antioxidative potential and through the modulation of the apoptotic signalling pathway. Therefore, gamma-mangostin may be an effective xanthone among other mangostins for preventing neurodegeneration in PD caused by oxidative stress. PMID- 29195912 TI - Procedure-Specific Trends in Surgical Outcomes. AB - BACKGROUND: Quality improvement efforts have generally focused on hospital benchmarking, and processes and outcomes shared among all operations. However, quality improvement could be inconsistent across different types of operations. The objective of this study was to identify operations needing additional concerted quality improvement efforts by examining their outcomes trends. STUDY DESIGN: Ten procedures (colectomy, esophagectomy, hepatectomy, hysterectomy, pancreatectomy, proctectomy, total hip arthroplasty, total knee arthroplasty, thyroidectomy, and ventral hernia repair) commonly accrued into the American College of Surgeons NSQIP between 2008 and 2015 were included. Trends in risk adjusted, standardized, smoothed rates were constructed for each procedure across 6 outcomes (mortality, pneumonia, renal failure, surgical site infection, unplanned intubation, and urinary tract infection [UTI]). RESULTS: Of 1,255,575 operations analyzed, the overall unadjusted rate for mortality across all 10 procedures was 1.08%, for pneumonia 1.44%, for renal failure 0.67%, for surgical site infection 5.28%, for unplanned intubation 1.11%, and for UTI 1.86%. Hepatectomy demonstrated the greatest improvement across outcomes (4 of 6 outcomes; 362 adverse events avoided out of 10,000 procedures), and UTI demonstrated the greatest improvement across procedures (8 of 10 procedures; 989 adverse events avoided out of 10,000). For pancreatectomy, rates of mortality, unplanned intubation, and UTI improved, but surgical site infection rates were detected to have significantly increased (p < 0.05). CONCLUSIONS: Hepatectomy was detected to have improved across the greatest number of outcomes, and UTI rates improved significantly across the greatest number of procedures. Surgical site infection rates after pancreatectomy, however, were detected to have increased, identifying an urgent need for additional concerted quality improvement efforts. PMID- 29195913 TI - Association of office and ambulatory blood pressure with blood lead in workers before occupational exposure. AB - In view of decreasing lead exposure and guidelines endorsing ambulatory above office blood pressure (BP) measurement, we reassessed association of BP with blood lead (BL) in 236 newly employed men (mean age, 28.6 years) without previous lead exposure not treated for hypertension. Office BP was the mean of five auscultatory readings at one visit. Twenty-four-hour BP was recorded at 15- and 30-minute intervals during wakefulness and sleep. BL was determined by inductively coupled plasma mass spectrometry. Systolic/diastolic office BP averaged 120.0/80.7 mm Hg, and the 24-hour, awake, and asleep BP 125.5/73.6, 129.3/77.9, and 117.6/65.0 mm Hg, respectively. The geometric mean of blood lead was 4.5 MUg/dL (interquartile range, 2.60-9.15 MUg/dL). In multivariable-adjusted analyses, effect sizes associated with BL doubling were 0.79/0.87 mm Hg (P = .11/.043) for office BP and 0.29/-0.25, 0.60/-0.10, and -0.40/-0.43 mm Hg for 24 hour, awake, and asleep BP (P >= .33). Neither office nor 24-hour ambulatory hypertension was related to BL (P >= .14). A clinically relevant white coat effect (WCE; office minus awake BP, >=20/>=10 mm Hg) was attributable to exceeding the systolic or diastolic threshold in 1 and 45 workers, respectively. With BL doubling, the systolic/diastolic WCE increased by 0.20/0.97 mm Hg (P = .57/.046). Accounting for the presence of a diastolic WCE, reduced the association size of office diastolic BP with BL to 0.39 mm Hg (95% confidence interval, -0.20 to 1.33; P = .15). In conclusion, a cross-sectional analysis of newly hired workers before lead exposure identified the WCE as confounder of the association between office BP and BL and did not reveal any association between ambulatory BP and BL. PMID- 29195911 TI - The central extended amygdala in fear and anxiety: Closing the gap between mechanistic and neuroimaging research. AB - Anxiety disorders impose a staggering burden on public health, underscoring the need to develop a deeper understanding of the distributed neural circuits underlying extreme fear and anxiety. Recent work highlights the importance of the central extended amygdala, including the central nucleus of the amygdala (Ce) and neighboring bed nucleus of the stria terminalis (BST). Anatomical data indicate that the Ce and BST form a tightly interconnected unit, where different kinds of threat-relevant information can be integrated to assemble states of fear and anxiety. Neuroimaging studies show that the Ce and BST are engaged by a broad spectrum of potentially threat-relevant cues. Mechanistic work demonstrates that the Ce and BST are critically involved in organizing defensive responses to a wide range of threats. Studies in rodents have begun to reveal the specific molecules, cells, and microcircuits within the central extended amygdala that underlie signs of fear and anxiety, but the relevance of these tantalizing discoveries to human experience and disease remains unclear. Using a combination of focal perturbations and whole-brain imaging, a new generation of nonhuman primate studies is beginning to close this gap. This work opens the door to discovering the mechanisms underlying neuroimaging measures linked to pathological fear and anxiety, to understanding how the Ce and BST interact with one another and with distal brain regions to govern defensive responses to threat, and to developing improved intervention strategies. PMID- 29195914 TI - Early fluid loading for septic patients: Any safety limit needed? AB - Early adequate fluid loading was the corner stone of hemodynamic optimization for sepsis and septic shock. Meanwhile, recent recommended protocol for fluid resuscitation was increasingly debated on hemodynamic stability vs risk of overloading. In recent publications, it was found that a priority was often given to hemodynamic stability rather than organ function alternation in the early fluid resuscitation of sepsis. However, no safety limits were used at all in most of these reports. In this article, the rationality and safety of early aggressive fluid loading for septic patients were discussed. It was concluded that early aggressive fluid loading improved hemodynamics transitorily, but was probably traded off with a follow-up organ function impairment, such as worsening oxygenation by reduction of lung aeration, in a part of septic patients at least. Thus, a safeguard is needed against unnecessary excessive fluids in early aggressive fluid loading for septic patients. PMID- 29195915 TI - Development and in-vitro characterization of nanoemulsions loaded with paclitaxel/gamma-tocotrienol lipid conjugates. AB - Vitamin E TPGS is a tocopherol (alpha-T) based nonionic surfactant that was used in the formulation of the TocosolTM paclitaxel nanoemulsion, which was withdrawn from phase III clinical trials. Unlike tocopherols, however, the tocotrienol (T3) isomers of vitamin E were found to have innate anticancer activity and were shown to potentiate the antitumor activity of paclitaxel. The primary objective of the present study was therefore to develop a paclitaxel nanoemulsions by substituting alpha-T oil core of TocosolTM with gamma-T3 in, and vitamin E TPGS with PEGylated gamma-T3 as the shell, and test the nanoemulsions against Bx-PC-3 and PANC-1 pancreatic tumor cells. A secondary objective was to test the activity of paclitaxel when directly conjugated with the gamma-T3 isomer of vitamin E. The synthesis of the conjugates was confirmed by NMR and mass spectroscopy. Developed nanoemulsions were loaded with free or lipid conjugated paclitaxel. Nanoemulsions droplets were <300 nm with fastest release observed with formulations loaded with free paclitaxel when gamma-T3 was used as the core. Substituting alpha-T with gamma-T3 was also found to potentiate the anticancer activity of the nanoemulsions. Although marginal increase in activity was observed when nanoemulsions were loaded with free paclitaxel, a significant increase in activity was observed when lipid conjugates were used. The results from this study suggest that the developed paclitaxel nanoemulsions with either gamma-T3, PEGylated gamma-T3, or paclitaxel lipid conjugates may represent a more promising option for paclitaxel delivery in cancer chemotherapy.

AB - Paclitaxel (PTX) and docetaxel (DTX) are highly effective chemotherapeutic agents against breast cancer cells. Existing PTX and DTX formulations, however, contain excipients that result in a multitude of side-effects. The objective of the present study was to develop novel self-microemulsifying formulations of PTX and DTX with significantly lower excipient content by utilizing the high solubility of taxanes in sulforaphane (SFN). SFN-enabled microemulsions were developed by a screening process in which optical microscopy and absorbance data were used to monitor the physical stability of the dispersions. Optimized formulations contained vitamin E TPGS and transcutol to aid in taxane dissolution in water and the formation of transparent microemulsions (< 20 nm). SFN microemulsions were stable in different dilution media and storage temperatures and had no hemolytic effect on RBCs. When tested in vitro against MDA-MB-231 and MCF7 cancer cells by IncuCyte(r) live cell analysis and CellTiter-Blue(r) assay, taxanes/SFN microemulsions showed similar activity as the commercial taxanes injection solutions. SFN was only found to potentiate the activity of taxanes when used at high concentrations. This study highlighted the unique properties of SFN and its potential use in reformulating taxanes with high drug load and significantly lower excipient content than the commercial products.

AB - Bone tissue engineering is considered an alternative approach for conventional strategies available to treat bone defects. In this study, we have developed bone scaffolds composed of hydroxyapaptite (HAp), gelatin and mesoporous silica, all recognized as promising materials in bone tissue engineering due to favorable biocompatibility, osteoconductivity and drug delivery potential, respectively. These materials were coupled with conductive polypyrrole (PPy) polymer to create a novel bone scaffold for regenerative medicine. Conductive and non-conductive scaffolds were made by slurry casting method and loaded with a model antibiotic, vancomycin (VCM). Their properties were compared in different experiments in which scaffolds containing PPy showed good mechanical properties, higher protein adsorption and higher percentage of VCM release over a long duration of time compared to non-conductive scaffolds. Osteoblast cells were perfectly immersed into the gelatin matrix and remained viable for 14 days. Overall, new conductive composite bone scaffolds were created and the obtained results strongly verified the applicability of this conductive scaffold in drug delivery, encouraging its further development in tissue engineering applications. PMID- 29195918 TI - Characterization and in vivo efficacy of a heptapeptide ODT formulation for the treatment of neurogenic bladder dysfunction. AB - The objective of this study was to develop oral disintegrating tablet (ODT) formulations of a heptapeptide, [Lys5,MeLeu9,Nle10]-NKA(4-10), for the treatment of neurogenic bladder dysfunction. A design of experiment approach was applied to determine the optimal ratio of chosen excipients: gelatin (X1), glycine (X2), and sorbitol (X3). These formulations were optimized for efficacy studies to produce ODTs exhibiting rapid disintegration times (Y1) and appropriate structural integrity (Y2) using JMP(r) 12.0.1 software. Based on theoretically predicted values from 12 experimental runs, the optimal ODT formulation was determined to be 3% (w/v) gelatin, 2% (w/v) glycine, and 1% (w/v) sorbitol in deionized water. Using this formulation, blank and drug-loaded ODTs containing 1.5 mg or 5 mg of [Lys5,MeLeu9,Nle10]-NKA(4-10) were manufactured by a lyophilization process. The peptide-loaded tablets disintegrated in less than 30 s and released 97% of the peptide within 15 min. The peptide was stable for 90 days under 25 degrees C/60% relative humidity (RH) and 40 degrees C/75% RH. In vivo efficacy of the peptide loaded ODTs was confirmed in a rat acute spinal cord injury model under isovolumetric bladder pressure recording conditions, concluding that sublingual administration of peptide-containing ODTs evoke a rapid dose-related neurokinin 2 mediated increase in bladder pressure. PMID- 29195920 TI - Loss of Lypd6 leads to reduced anxiety-like behaviour and enhanced responses to nicotine. AB - Nicotine consumption through smoking affects anxious states in humans. However, the precise role of nicotinic acetylcholine receptor (nAChR) circuitry in the regulation of anxiety remains elusive. The Lynx protein Lypd6 is highly enriched in synaptic loci and has been previously identified as an endogenous inhibitor of neuronal nAChR function in vitro. Here, we investigate the effect of Lypd6 in anxiety-related behaviour and examine the molecular underpinnings of its function in the brain. We employ the marble burying (MB) and elevated zero maze (EZM) tests in Lypd6 knock-out (KO) and wild-type (WT) mice and find that loss of Lypd6 leads to decreased digging behaviour in the MB test and increased time spent in the open area in the EZM test. Moreover, we demonstrate that acute nicotine administration reduces digging in the MB test in both KO and WT mice and further accentuates the inherent genotype difference. Using in vitro electrophysiology in dorsal raphe nuclei (DRN) neurons from Lypd6 KO mice, we show that nicotine evoked whole-cell currents are enhanced in the absence of Lypd6. Collectively, these data are the first to indicate the involvement of Lypd6 in circuits associated with anxiety and suggest that a possible underlying neurobiological mechanism is the modulation of cholinergic responses in the DRN. PMID- 29195919 TI - S-Glutathionylation of p47phox sustains superoxide generation in activated neutrophils. AB - Post-translational modifications (PTMs) induced conformational changes of proteins can cause their activation or inactivation. Neutrophils clear pathogen through phagocytosis and oxidative burst generation, while participate in inflammation through sustained and uncontrolled generation of ROS. In activated PMNs, cytosolic NOX-2 subunit p47phox following phosphorylation interacts with p67phox, p40phox and along with Rac2 translocate to the membrane. Phosphorylation of p47phox subunit occurs in both short spurts as well as sustained ROS generation, suggesting towards the unidentified molecular mechanism(s) driving these two diverse outcomes by various stimuli. The present study demonstrates that in PMA or NO treated neutrophils a subunit of NOX2, p47phox gets glutathionylated to sustain ROS generation along with a decrease in catalase, Grx 1 activity and change in GSH/GSSG ratio. Surprisingly, fMLP treated cells neither showed sustained ROS production nor glutathionylation of p47phox. S Glutathionylation was always secondary to phosphorylation of p47phox and inhibition of glutathionylation did not alter phosphorylation but specifically impaired sustained ROS production. Interestingly, forced S-glutathionylation of p47phox converted the fMLP induced ROS generation into sustained release of ROS. We then identified the glutathionylation susceptible cysteine residues of p47phox by LC-MS/MS with IAM switch mapping. Site-directed mutagenesis of cysteine residues further mitigated p47phox S-glutathionylation. Thus, we demonstrate that p47phox S-glutathionylation plays an essential key role in the sustained ROS generation by human neutrophils. PMID- 29195921 TI - Social cognition and self-other distinctions in neuropsychiatry: Insights from schizophrenia and Tourette syndrome. AB - Impairments in social cognition may reflect dysfunction of disorder specific or disorder general mechanisms. Although cross-disorder comparison may prove insightful, few studies have compared social cognition in different neuropsychiatric disorders. Parallel investigation of schizophrenia and Tourette syndrome (TS) is encouraged by similarities including the presence of problematic social behavior, echophenomena, emotional dysregulation and dopamine dysfunction. Focusing on tests of social cognition administered in both disorders, this review aims to summarize behavioral, neurophysiological and neuroimaging findings, before exploring how these may contribute to clinical symptoms. Studies investigating social cognition (imitation, emotion recognition, and understanding of beliefs or intentions) in patients with schizophrenia or TS were identified through Web of Science and PubMed searches. Although findings indicate that social cognitive deficits are more apparent in schizophrenia, adults with TS can exhibit similar task performance to patients with paranoia. In both disorders, behavioral and neuroimaging findings raise the possibility of increased internal simulation of others' actions and emotions, in combination with a relative under application of mentalizing. More specifically, dysfunction in neurobiological substrates such as temporo-parietal junction and inferior frontal gyrus may underlie problems with self-other distinctions in both schizophrenia and TS. Difficulties in distinguishing between actions and mental states linked to the self and other may contribute to a range of psychiatric symptoms, including emotional dysregulation, paranoia, social anhedonia and socially disruptive urges. Comparing different patient populations could therefore reveal common neuro-cognitive risk factors for the development of problematic social behaviors, in addition to markers of resilience, coping strategies and potential neuro compensation mechanisms. PMID- 29195922 TI - Association Between Cardiorespiratory Fitness and Health Care Costs: The Veterans Exercise Testing Study. AB - OBJECTIVE: To determine the association between cardiorespiratory fitness (CRF) and annual health care costs in Veterans. PATIENTS AND METHODS: The sample included 9942 subjects (mean age, 59+/-11 years) undergoing a maximal exercise test for clinical reasons between January 2005 and December 2012. Cardiorespiratory fitness, expressed as a percentage of age-predicted peak metabolic equivalents (METs) achieved, was categorized in quartiles. Total and annualized health care costs, derived from the Veterans Administration Allocated Resource Center, were compared using multiple regression, controlling for demographic and clinical characteristics. RESULTS: A gradient for reduced health care costs was observed as CRF increased, with subjects in the least-fit quartile having approximately $14,662 (P<.001) higher overall costs per patient per year compared with those in the fittest quartile, after controlling for potential confounding variables. Each 1-MET higher increment in fitness was associated with a $1592 annual reduction in health care costs (5.6% lower cost per MET), and each higher quartile of fitness was associated with a $4163 annual cost reduction per patient. The effect of CRF was more pronounced among subjects without cardiovascular disease (CVD), suggesting that the results were not driven by the possibility that less-fit individuals had greater CVD. Cost savings attributable to higher fitness were greatest in overweight and obese subjects, with lower savings observed among those individuals with a body mass index less than 25 kg/m2. In a model including historical, clinical, and exercise test responses, heart failure was the strongest predictor of health care costs, followed by CRF (P<.01). CONCLUSION: Low CRF is associated with higher health care costs. Efforts to improve CRF may not only improve health but also result in lower health care costs. PMID- 29195923 TI - Calcific tendonitis of the rotator cuff: From formation to resorption. AB - Calcific tendonitis of the rotator cuff is due to apatite deposits in the shoulder tendons. Patients affected by calcific tendonitis have chronic shoulder pain and disability. Although the disease is frequent, about 10 to 42% of painful shoulders, mechanisms leading to this pathological mineralization are still largely unknown. Research reported in the 1990s suggested that the formation of calcific deposits is linked to cells looking like chondrocytes identified around calcium deposits within a fibrocartilage area. They were considered to be derived from tenocytes but more recently, tendon stem cells, able to differentiate into chondrocytes, were isolated. The pro-mineralizing properties of these chondrocytes-like cells, especially the role of alkaline phosphatase, are not currently clarified. The calcium deposits contain poorly crystalline carbonated apatite associated with protein. Among these proteins, only osteopontin has been consistently identified as a potential regulating factor. During the disease, spontaneous resorption can occur with migration of apatite crystals into the subacromial bursa causing severe pain and restriction of movement. In in vivo and in vitro experiments, apatite crystals were able to induce an influx of leucocytes and a release of IL-1beta and IL-18 through the activation of the NLRP3 inflammasome. However, mechanisms leading to spontaneous resolution of this inflammation and disappearance of the calcification still need to be elucidated. PMID- 29195924 TI - Adverse Reactions to Vaccination: From Anaphylaxis to Autoimmunity. AB - Vaccines are important for providing protection from infectious diseases. Vaccination initiates a process that stimulates development of a robust and long lived immune response to the disease agents in the vaccine. Side effects are sometimes associated with vaccination. These vary from development of acute hypersensitivity responses to vaccine components to local tissue reactions that are annoying but not significantly detrimental to the patient. The pathogenesis of these responses and the consequent clinical outcomes are discussed. Overstimulation of the immune response and the potential relationship to autoimmunity is evaluated in relation to genetic predisposition. PMID- 29195925 TI - Another Look at the "Dismal Science" and Jenner's Experiment. AB - The follow-up to Jenner's experiment, routine vaccination, has reduced more disease and saved more vertebrate lives than any other iatrogenic procedure by orders of magnitude. The unassailability of that potentially provocative cliche has been ciphered in human medicine, even if it is more difficult in our profession. Most public relations headaches concerning vaccines are a failure to communicate, often resulting in overly great expectations. Even in the throes of a tight appointment schedule remembering and synopsizing (for clients), some details of the dismal science can make practice great again. PMID- 29195927 TI - Effect of fish gelatin-gum arabic interactions on structural and functional properties of concentrated emulsions. AB - Concentrated emulsions containing both proteins and polysaccharides are the basis for many commercial products; however, the effects of protein-polysaccharide interactions on the functional properties of these complex systems are often poorly understood from a fundamental standpoint. Hence, the objective of this study was to determine the effects of fish gelatin (FG)-gum arabic (GA) complexation at different aqueous phase pH (3.6, 5.0, and 9.0) on concentrated emulsion structure-function relationships. Concentrated emulsions were prepared using FG-GA mixtures and characterized by rheometry and confocal scanning laser microscopy (CSLM). CSLM images showed that all samples were O/W emulsions; emulsions with lower pH showed smaller oil droplets, greater homogeneity in size distribution, and higher stability. This was attributed to an increased number of FG-GA complexes in the emulsification. Electrostatic attractive interactions and charge neutralization created biopolymer associations with increased emulsification capacity. Samples with FG-GA mixtures at lower pH showed higher elastic moduli under small deformation and exhibited greater deviation between apparent and complex viscosities under the Cox-Merz rule, indicating increased gel network extension and greater intermolecular connectivity between adsorbed layers of adjacent oil droplets. These results can be used to incorporate protein polysaccharide complexes as a suitable emulsifier in materials comprising concentrated emulsions. PMID- 29195926 TI - Clinicopathologic characteristics associated with long-term survival in advanced epithelial ovarian cancer: an NRG Oncology/Gynecologic Oncology Group ancillary data study. AB - OBJECTIVE: To identify clinicopathologic factors associated with 10-year overall survival in epithelial ovarian cancer (EOC) and primary peritoneal cancer (PPC), and to develop a predictive model identifying long-term survivors. METHODS: Demographic, surgical, and clinicopathologic data were abstracted from GOG 182 records. The association between clinical variables and long-term survival (LTS) (>10years) was assessed using multivariable regression analysis. Bootstrap methods were used to develop predictive models from known prognostic clinical factors and predictive accuracy was quantified using optimism-adjusted area under the receiver operating characteristic curve (AUC). RESULTS: The analysis dataset included 3010 evaluable patients, of whom 195 survived greater than ten years. These patients were more likely to have better performance status, endometrioid histology, stage III (rather than stage IV) disease, absence of ascites, less extensive preoperative disease distribution, microscopic disease residual following cyoreduction (R0), and decreased complexity of surgery (p<0.01). Multivariable regression analysis revealed that lower CA-125 levels, absence of ascites, stage, and R0 were significant independent predictors of LTS. A predictive model created using these variables had an AUC=0.729, which outperformed any of the individual predictors. CONCLUSIONS: The absence of ascites, a low CA-125, stage, and R0 at the time of cytoreduction are factors associated with LTS when controlling for other confounders. An extensively annotated clinicopathologic prediction model for LTS fell short of clinical utility suggesting that prognostic molecular profiles are needed to better predict which patients are likely to be long-term survivors. PMID- 29195928 TI - Acoustic cavitation assisted extraction of pectin from waste grapefruit peels: A green two-stage approach and its general mechanism. AB - In the present study, acoustic cavitation assisted extraction (ACAE) which is a green approach was used for two-stage extraction of pectin from waste grapefruit peels regarding the specific two stages and different peel particle sizes. The yields, physicochemical properties and structure prediction of pectin from different peel particle sizes and different stages by two methods were compared. Highest pectin yield of 23.49% was achieved at the peel size of 0.9mm and was slightly higher than the yield of 23.44% at finer particle size. ACAE achieved four times higher yield compared with conventional heating method (CHE) at the second stage. ACAE pectin which had lower molecular weight and degree of methoxylation was richer in rhamnogalacturonan-I (RG-I) region with long side chains compared with CHE pectin from chemical and FT-IR analysis. Based on the results, a potential general mechanism for ACAE of plant cell wall viscous polysaccharides was discussed in terms of the effects of cavitation on the swelling index and morphological study of residue to reveal the "barrier effect" during the process. Furthermore, the energy consumption for ACAE was significantly lower than the conventional method, indicating its promising application in industrial scale. PMID- 29195929 TI - Foam-stabilizing properties of the yeast protein PAU5 and evaluation of factors that can influence its concentration in must and wine. AB - The absence of the yeast protein seripauperin 5 (PAU5) from Saccharomyces cerevisiae has been suggested as a biomarker for the occurrence of gushing in sparkling wine as samples lacking PAU5 were found to be more susceptible to gushing. In this study, further characterization of PAU5 regarding its foam stabilizing properties was performed to elucidate whether PAU5 has foam stabilizing properties and therefore, to elucidate a direct influence on the gushing potential of sparkling wines. PAU5 was successfully purified from non gushing sparkling wine using reversed-phase high-performance liquid chromatography (RP-HPLC). Pure protein was added to grape juice as a model system for grape must prior to foam stability testing. The results revealed that the protein PAU5 has foam-stabilizing properties. Furthermore, the influence of heat and sulfur treatment in the presence of Botrytis cinerea was analyzed with regard to the amount of PAU5 produced by S. cerevisiae fermented in grape juice. Fermentation experiments using two different S. cerevisiae strains were performed, and the concentration of PAU5 in the samples was compared by RP-HPLC analysis. Unlike sulfur treatment, heat treatment prevented the protein degradation induced by B. cinerea and resulted in even higher amounts of PAU5 compared to the juice fermented with yeast without a previous botrytization. The two different yeast strains applied secreted PAU5 into the surrounding medium in different amounts. In further experiments, the fining process of the wine with bentonite was examined for its potential to remove PAU5 from the wine. RP-HPLC of wines processed with different fining agents revealed that bentonite treatment affected PAU5 concentrations in the final product. The extent of PAU5 removal depended on the type of bentonite applied and on the time of addition during the production process. PMID- 29195930 TI - Chilean berry Ugni molinae Turcz. fruit and leaves extracts with interesting antioxidant, antimicrobial and tyrosinase inhibitory properties. AB - The knowledge of the biological properties of fruits and leaves of murta (Ugni molinae Turcz.) has been owned by native Chilean culture. The present study investigated the phenolic content, the antioxidant, antimicrobial and anti tyrosinase activities of different murta fruit and leaves extracts to approach their uses on future food, pharmaceutical and cosmetic applications. Extractions of murta fruit and leaves were carried out under water, ethanol and ethanol 50%. Phenolic content of these extracts was measured through Folin Ciocalteu test and the antioxidant power by four different antioxidant systems (ORAC, FRAP, DPPH and TEAC assays) owing to elucidate the main mechanism of antioxidant. Some flavonoids, such as rutin, isoquercitrin and quercitrin hydrate were identified and quantified through HPLC analysis. Antimicrobial activity was determined measuring minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) values against Escherichia coli and Listeria monocytogenes, and the effect of these extracts on L. monocytogenes was confirmed by flow cytometry. Highest contents of polyphenol compounds were obtained in hydroalcoholic extracts (28+/-1mggallicacid/g dry fruit, and 128+/ 6mggallicacid/g dry leaves). The same trend was found for the values of biological properties: hydroalcoholic extracts showed the strongest activities. Leaves presented higher antioxidant, antimicrobial and anti-tyrosinase properties than murta fruit. Highest antioxidant activity values according to ORAC, FRAP, TEAC and DPPH were 80+/-8mgTrolox/g, 70+/-2mgTrolox/g, 87+/-8mgTrolox/g and 110+/ 12mgTrolox/g, respectively, for murta fruit samples, and 280+/-10mgTrolox/g, 192+/-4mgTrolox/g, 286+/-13mgTrolox/g and 361+/-13mgTrolox/g, respectively, for murta leaves. These activities were confirmed by HPLC analysis that revealed highest presence of analyzed compounds on leaves hydroalcoholic extract. Regarding to antimicrobial analysis, hydroalcoholic leaves extract presented the highest activity presenting the lowest MIC value for L. monocytogenes (0.07mg/mL). This extract also performed the highest anti-tyrosinase activity (CE50 values of 1.6+/-0.3 (g/L) and 8.9+/-1.2 (g/L) for leaves and fruit, respectively). PMID- 29195931 TI - Effect of temperature in domestic refrigerators on fresh-cut Iceberg salad quality and waste. AB - The evolution of different quality parameters (firmness, weight loss, colour changes, microbial counts, consumer rejection) of packed fresh-cut Iceberg salad was assessed at 4, 8 and 12 degrees C to simulate domestic refrigerators running at different conditions. The increase in storage temperature did not affect salad firmness and weight loss but increased colour changes, microbial growth and consumer rejection. A survey among Italian consumers was also carried out and demonstrated that fresh-cut salad was mainly consumed within the first 5days after purchasing. Consumer rejection data were combined with data relevant to the distribution of salad consumption over the days following product purchase, to estimate salad wasting risk. When salad was stored at 4 and 8 degrees C, estimated wasted packages within the expiration date (7days) were <1%. By contrast, 13% of the packages was estimated to be wasted within 7days of storage at 12 degrees C. Quantification of wasting risk is a necessary information to identify efficient and sustainable interventions to tackle food waste. PMID- 29195932 TI - Effect of processing on phenolic acids composition and radical scavenging capacity of barley pasta. AB - Phenolic acids, total phenolics content and DPPH radical scavenging capacity in raw ingredients, fresh and dried spaghetti, and in uncooked and cooked spaghetti were evaluated and compared with semolina spaghetti as a reference. Ferulic acid was the major phenolic acid found in the free and bound phenolic extracts in all the investigated pasta samples. The addition of barley flour into pasta at incorporation levels of 30, 50 and 100% increased phenolic acids and total phenolics content. Pasta processing did not significantly affect the total phenolics content and free radical scavenging capacity, but a significant reduction in total phenolic acids measured by HPLC was found. Drying process differently affected individual phenolic compounds in the free and bound fractions, and thus, the total phenolic acids content. Free vanillic, caffeic and p-coumaric acids did not significantly change, while p-hydroxybenzoic and ferulic acids of the free extracts showed higher values compared to the corresponding fresh pasta. Cooking did not greatly affect total phenolic acids, more leading to conserving free and bound phenolic compounds. PMID- 29195933 TI - Effect of the molecular weight of a neutral polysaccharide on soy protein gelation. AB - The effects of galactomannans with different molecular weights on the heat induced gelation characteristics of soybean protein were investigated using dynamic small-strain rheometry, under conditions where the proteins carry a net negative charge (pH7). Microstructure of the resulting gels was investigated by confocal laser scanning microscopy. Phase-separated systems were obtained with different morphologies and degree of phase separation, depending on both biopolymer concentrations and polysaccharide molecular weight. In general, a gelling enhancing effect on soy proteins was verified, despite extensive phase separation processes observed at the higher polysaccharide molecular weight. This effect was demonstrated by an increase of the gelation rate, a decrease in the temperature at the onset of gelation, and an increase of gel stiffness and elastic character, with the length of polysaccharide chains. Overall, the results obtained established that the judicious selection of the galactomannan molecular weight may be used to modify the structure and gelation properties of soy proteins, originating a diversity of rheological characteristics and microstructures that will impact on the design of novel food formulations. PMID- 29195934 TI - Photocrosslinker technology: An antimicrobial efficacy of cinnamaldehyde cross linked low-density polyethylene (Cin-C-LDPE) as a novel food wrapper. AB - In recent years much attention has been devoted to active packaging technologies that offer new opportunities for the food industry and food preservation. The spoilage of food products during post process handling leads to food contamination and causes life-threatening food-borne illness. The methicillin resistant Staphylococcus aureus (MRSA) 090 is one of the food-borne pathogens associated with food poisoning that leads to an outbreak of perilous human infections worldwide. The development of resistance in bacteria and diffusion of coated synthetic preservatives into food are the major problem in food packaging industries. In the present work, we have developed a new food wrap method by cross-linking cinnamaldehyde on low-density polyethylene (Cin-C-LDPE) using novel photocrosslinker technology. The cinnamaldehyde showed potent antimicrobial activity (145mg/mL of MIC) against MRSA 090 and radical scavenging activity (RSA). The cinnamaldehyde was successfully cross-linked to LDPE and exhibited excellent antibiofilm properties against MRSA090 compared to bare LDPE. This positive interaction of developed Cin-C-LDPE against MRSA090 biofilm was confirmed by SEM and FT-IR studies, and results showed the damaged cell membrane architecture, inturn abridged adherence of MRSA090. The Cin-C-LDPE wrapped chicken, mutton, cheese, and grapes showed 2.5+/-0.15 log MRSA 090 reduction at the end of 10th day compared to the bare LDPE wrapped food samples. This clearly concludes that for the first time we have developed a novel Cin-C-LDPE food wrap technology effectively involved in biocidal activity against MRSA090. Applying this new strategy to develop food wrap containing nontoxic natural antimicrobial to target cell membrane components is the upcoming challenging and promising research gap remains in the food packaging industry for the future world. PMID- 29195935 TI - Effect of in vitro simulated gastrointestinal digestion on polyphenol and polysaccharide content and their biological activities among 22 fruit juices. AB - Polyphenols and polysaccharides, as natural bioactive compounds from common fresh fruits, are concerned in reducing risk of developing obesity and diabetes for human in recent years. The content of polyphenol and polysaccharide, their bioactivities among 22 fruit juices were investigated before and after in vitro gastrointestinal digestion in present study. After digestion, contents of polyphenol, polysaccharide and their antioxidant activity, the inhibitory activity of alpha-amylase and alpha-glucosidase significantly increased. Punica granatum Linn and Actinidia globosa C. F. Liang displayed maximal increment up to 2, 0.25 and 1.6 fold in contents of polyphenols and polysaccharides, and the inhibitory activity of alpha-amylase, respectively. The correlation coefficient between contents and inhibitory activity of alpha-amylase increased in range of 0.002 to 0.485. Lycopersicon esculentum Mill and Pyrus bretschneideri Rehd exhibited maximum increase in the inhibitory activity of alpha-glucosidase with lowest contents of polyphenols and polysaccharides. The results indicated that polyphenols and polysaccharides digested synergistically contributing to the inhibitory alpha-amylase activity, and other responsibly bioactive ingredients for inhibitory alpha-glucosidase activity would be worthy discussed future. The findings above highlighted some potential application of common fruit juices in controlling hyperglycemia and obesity. PMID- 29195936 TI - 1H NMR-based metabolomic fingerprinting to determine metabolite levels in serrano peppers (Capsicum annum L.) grown in two different regions. AB - Chili pepper (Capsicum annuum) is the most important and emblematic condiment in Mexican food. Serrano pepper is a variety of C. annuum that is traditionally cultivated in Mexico and commercialized in local markets. The aim of this study was to describe the 1H NMR metabolomic profiling of the aqueous phase of serrano peppers harvested from two distinct regions, in the states of Veracruz and Oaxaca, Mexico. According to the current results, aspartate citrate, lactate, leucine and sucrose were found at higher amount in the serrano peppers from Veracruz. On the other hand, acetate, formate, fumarate, malonate, phosphocholine, pyruvate and succinate showed the highest abundance in this product from Oaxaca. These are the main metabolites that distinguish one group from the other. The spectrometric method reported presently is characterized by great simplicity, robustness and reproducibility. Thus, this technique can be used for establishing reliable metabolomic fingerprints of serrano peppers grown under different environmental conditions. PMID- 29195937 TI - The French, German, and Spanish sound of eating fresh fruits and vegetables. AB - A set of onomatopoeic expressions for eating fruits and vegetables is compared across subjects whose native language is Spanish, French, or German. Subjects chose the onomatopoeia that best represented the sound of eating a fruit or vegetable (celery, banana, strawberry, passion fruit, mango, apple, orange, and tomato). Results show there are onomatopoeias that have a higher frequency of response in one language compared to the others. Thus, it is possible to assume that depending on the language there is a better way to express haptic and auditory information associated to fruit and vegetable consumption. Moreover, and considering the three languages, results show there are three categories of responses based on the relative strength of the material (strong and medium strength, and soft). Thus, there is some consistency in the onomatopoeias that represent the sound of eating a fruit or a vegetable. To conclude, results differ by language, but they are consistent within a category of sound. PMID- 29195938 TI - Technological aspects of horse meat products - A review. AB - Horse meat and its products can be considered as a food with a high nutritional value. However, due to cases of economically motivated food adulteration by the intentional addition of horse meat beef products in recent years, horse meat has become a controversial issue. Consumer confidence in meat products and the meat industry has diminished, although consumers consider the differences between the food content and the label as the major issue rather than the safety and nutritional characteristics of horse meat. The elaboration of meat products from horse meat (e.g. "cecina", dry-cured loin, salami, bressaola and pate) is also an interesting alternative to other traditional meat products such as dry-cured pork hams, pork sausages and liver pates. In this review, the technological aspects, safety and storage stability of meat products elaborated from horse meat will be addressed by highlighting the nutritional and sensory aspects of these meat products. We aim to improve the existing knowledge about horse meat in the view of recent scandals. PMID- 29195939 TI - Profiling and quantification of phenolic compounds in Camellia seed oils: Natural tea polyphenols in vegetable oil. AB - In Asia, tea seed oils (seed oils from Camellia oleifera, C. chekiangoleosa, and C. sinensis) are used in edible, medicinal, and cosmetic applications. However, these oils differ in their fatty acid contents, and there is little known about their phenolic compounds. Here we analyzed the phenolic compounds of seed oils from three species gathered from 15 regions of China. Twenty-four phenolic compounds were characterized by HPLC-Q-TOF-MS, including benzoic acids (6), cinnamic acids (6), a hydroxyphenylacetic acid, flavanols (4), flavonols (3), flavones (2), and dihydroflavonoids (2). Some of these phenolic compounds had not previously been reported from C. sinensis (20), C. oleifera (15), and C. chekiangoleosa (24) seed oils. Quantification was done by HPLC-QqQ-MS using 24 chemical standards. The total concentrations in the studied samples ranged from 20.56 to 88.56MUg/g. Phenolic acids were the most abundant class, accounting for 76.2-90.4%, with benzoic acid, found at up to 18.87MUg/g. The concentration of catechins, typical of tea polyphenols, ranged between 2.1% and 9.7%, while the other flavonoids varied from 4.2% to 17.8%. Although the cultivation region affected the phenolic composition of the Camellia seed oils, in our hierarchical clustering analysis, the samples clustered according to species. The phenolic composition of the seed oils from C. oleifera and C. chekiangoelosa were similar. We found that the phenolic categories in Camellia seed oils were similar to tea polyphenols, thereby identifying a source of liposoluble tea polyphenols and potentially accounting for some of the reported activities of these oils. In addition, this work provides basic data that allows distinction of various Camellia seed oils, as well as improvements to be made in their quality standards.

AB - Tannic acid (TA) shows strong interactions with proteins and the resulting complexes can be utilized as delivery systems for oral drugs. The complexation of TA with three proteins including bovine serum albumin (BSA), egg ovalbumin (EA) and bovine beta-lactoglobulin (BLG) at pH 7.4 was studied. The tryptophan (Trp) fluorescence of all three proteins was quenched by TA in a static quenching mechanism. BLG showed the highest binding affinity and a smallest binding distance with TA which may suggest that BLG-TA is the most stable complex. The results of circular dichroism, synchronous and three-dimensional fluorescence spectra suggested that the protein structures have been changed at different levels and helix structure was affected more significant than beta-strand. Zeta potential of all three proteins was more negative after binding with TA, which is favorable for the stabilization of protein based nanoparticles. Information derived from this work could be important to potentially use TA-protein complexes as nanoencapsulation systems for oral drug delivery.

AB - In recent years, research studies have shown that the thermal resistance of foodborne pathogens in the low moisture foods is greatly influenced by the water activity (aw) at temperatures relevant to thermal treatments for pathogen control. Yet, there has been a lack of an effective method for accurate measurement of aw at those temperatures. Thus, the main aim of this study was to evaluate a new method for measuring aw of food samples at elevated temperatures. An improved thermal cell with a relative humidity and temperature sensor was used to measure the aw of the three different food samples, namely, organic wheat flour, almond flour, and non-fat milk powder, over the temperature range between 20 and 80 degrees C. For a constant moisture content, the aw data was used to estimate the net isosteric heat of sorption (qst). The qst values were then used in the Clausius Clapeyron equation (CCE) equation to estimate the moisture sorption isotherm for all test food samples at different temperatures. For all the tested samples of any fixed moisture content, aw value generally increased with the temperature. The energy for sorption decreased with increasing moisture content. With the experimentally determined qst value, CCE describes well about the changes in aw of the food samples between 20 and 80 degrees C. This study presents a method to obtain aw of a food sample for a specific moisture content at different temperatures which could be extended to obtain qst values for different moisture contents and hence, the moisture sorption isotherm of a food sample at different temperatures.

AB - Type 2 diabetes is a chronic disease and hyperglycemia is important in the pathogenesis of diabetic complications. Exposure of LO2 cells to high glucose resulted in cellular glucose consumption and uptake decreases, reactive oxygen species (ROS) and superoxide anion (O2-) accumulation and mitochondrial dysfunction, which could be partly recovered by mulberry anthocyanin extract (MAE). And these protective effects were partly associated with regulation of nuclear factor erythroid 2-related factor 2 (Nrf2) and its downstream targets. As the insulin-signaling pathway is evolutionarily well conserved from Caenorhabditis elegans to mammals, C. elegans has been considered as a model system to study effects of glucose toxicity. Glucose shortened the lifespan of C. elegans, while MAE suppressed the damage, accompanied by malondialdehyde (MDA) and triglyceride accumulation reduction as well as total superoxide dismutase (SOD) and glutathione peroxidase (GPx) activity recovery and PMK-1/p38 expression promotion. In contrast, MAE failed to recover shortened longevity, glucose and triglyceride accumulation in daf-2 (-) mutants fed a glucose-supplemented diet. Transcriptional profile revealed MAE intervention led to 92 genes alteration compared with the glucose-treatment. Interestingly, expressions of DAF-2/insulin receptor related genes were increased by glucose but impaired by MAE in nematodes. Our studies suggested that MAE might help to improve the antioxidant defense system, resulting in prevention of glucose-induced damage both in vitro and in vivo.

AB - In our previous studies, soluble soybean protein hydrolysate (SPH)-calcium complexes were shown to promote the calcium uptake of Caco-2 cells. However, the calcium transport mode involved remains unknown. In this article, several experiments were carried out via cytological analysis to investigate the calcium transport mode of peptides with low calcium binding capacities (F1), peptides with high calcium-binding capacities (F2), and their separate calcium complexes (F1-Ca and F2-Ca) when interacting with cell membranes. The interaction between one of them and a cell membrane is the first step in intracellular transport, as indicated by fluorescence blue shift experiments and acrylamide quenching experiments. The results of zeta potential experiments showed that only the "charge neutralization" phenomenon occurs when the F1 peptide or F1-Ca complex interacts with cell membranes and thus cannot be transported into cells. On the contrary, in an F2 at high concentrations or F2-Ca complex, a "charge recovery" phenomenon occurs apart from "charge neutralization" and can thus be transported into cells through endocytosis.

AB - Microcystin (MC), a hepatotoxin that can adversely affect human health, has become more prevalent in freshwater ecosystems worldwide, owing to an increase in toxic cyanobacteria blooms. While consumption of water and fish are well documented exposure pathways of MCs to humans, less is known about the potential transfer to humans through consumption of vegetables that have been irrigated with MC-contaminated water. Likewise, the impact of MC on the performance of food crops is understudied. To help fill these information gaps, we conducted a controlled laboratory experiment in which we exposed lettuce, carrots, and green beans to environmentally relevant concentrations of MC-LR (0, 1, 5, and 10MUg/L) via two irrigation methods (drip and spray). We used ELISA and LC-MS/MS to quantify MC-LR concentrations and in different parts of the plant (edible vs. inedible fractions), measured plant performance (e.g., size, mass, edible leaves, color), and calculated human exposure risk based on accumulation patterns. MC-LR accumulation was positively dose-dependent, with it being greater in the plants (2.2-209.2MUg/kg) than in soil (0-19.4MUg/kg). MC-LR accumulation varied among vegetable types, between plant parts, and between irrigation methods. MC-LR accumulation led to reduced crop growth and quality, with MC-LR persisting in the soil after harvest. Observed toxin accumulation patterns in edible fractions of plants also led to estimates of daily MC-LR intake that exceeded both the chronic reference dose (0.003MUg/kg of body weight) and total daily intake guidelines (0.04MUg/kg of body weight). Because the use of MC-contaminated water is common in many parts of the world, our collective findings highlight the need for guidelines concerning the use of MC-contaminated water in irrigation, as well as consumption of these crops. PMID- 29195945 TI - Theoretical study of aerobic vitamin C loss kinetics during commercial heat preservation and storage. AB - The non-isothermal aerobic degradation of ascorbic acid (AA), and the formation and subsequent degradation of the dehydroascorbic acid (DHAA) are described by two simultaneous rate equations, assuming that all three underlying reactions follow first or other fixed order kinetics. Also assumed is that the temperature dependence of these three reactions' rate-constants follows the exponential model, a simpler substitute for the traditional Arrhenius equation. The effective momentary vitamin C's concentration is assumed to be the sum of the AA's and DHAA's momentary concentrations. Plots of the rate equations' numerical solutions for non-isothermal temperature histories, such as those that exist in actual heat preservation processes and commercial storage of foods, allow examining the temperature regime's role in the vitamin C's retention, at least qualitatively, and to evaluate its loss pattern when DHAA is initially absent or already present in the food. The temperature profile can be expressed algebraically or as an interpolating function constructed for digitized data. With the generalized model's version, characterization of the vitamin loss kinetics may require at least nine independent parameters, which ought to be known a priori, assumed on the basis of literature reports or determined experimentally. However, for many practical applications the number of kinetic parameters can be reduced to six. Isothermal loss is a special case, which can be used to test the calculation procedure by comparing the numerical solutions for quasi-isothermal temperature histories with the analytical solutions for truly isothermal temperature profiles. A version of the calculation and simulation procedure has been posted on the Internet as a freely downloadable interactive Wolfram Demonstration, which can be used as a tool to examine the effect of actual and hypothetical temperature histories on the vitamin's retention during heat processing and storage. It can also be used to assess the impact of deviations from the assumed kinetic order and variability in the model's kinetic parameters on the vitamin's retention pattern. PMID- 29195946 TI - Rennet-induced coagulation properties of yak casein micelles: A comparison with cow casein micelles. AB - It is essential for yak cheese processing to understand the rennet-induced coagulation properties of gel formation from casein micelles. We have previously discovered that yak milk requires a longer incubation time but forms stronger gels compared with cow milk. In this study, we are aiming to understand the rennet-induced coagulation properties of yak casein micelles comparing with cow casein micelles. Rheological analyses revealed that the gelling times of yak and cow casein micelles were 11.6+/-0.5 and 8.7+/-0.4min (P<0.05) respectively, but yak casein gel had a higher elastic modulus G' (6.5+/-0.2Pa) than cow casein gel (2.5+/-0.2Pa; P<0.05). This is consistent with the results obtained by micro rheology. Confocal laser scanning microscopic images (CLSM) and cryo-scanning electron microscopic images (cryo-SEM) showed that yak casein gel was more homogeneous and had smaller pore size than cow casein gels. Yak casein micelles had higher calcium (26.00mM), phosphate (19.90mM) and beta-casein (relative 32%) concentrations. In addition, yak casein micelles were larger (Z-average 218.6nm) than cow casein micelles, and contained lower kappa-casein (relative 13%). By comparison with cow casein micelles, yak casein micelle composition corresponding to their micellar calcium phosphate and kappa-casein content may greatly contribute to the longer coagulation time and denser gel structure. An initial slower caseinomacropeptide (CMP) release rate and the slower rate of aggregation between para-casein micelles contributed to a more homogeneous yak gel network. Higher colloidal calcium phosphate is crucial for yak casein micelle aggregation and gel firmness because sufficient colloidal calcium phosphates can firmly glue sub-micelles and links casein micelles. This study provides valuable information for yak cheese production. PMID- 29195947 TI - Solubilization of industrial grade plant protein by enzymatic hydrolysis monitored by vibrational and nuclear magnetic resonance spectroscopy: A feasibility study. AB - Protein hydrolysates are of great interest in the food industry due to their nutritional and functional properties, but their use often implies solubilization in water and therefore hamper the use of plant proteins with inherent low water solubility. Protein solubility in water can be modified by enzymatic hydrolysis, but during this process several collateral properties of the protein hydrolysates changes. It is therefore important to determine the end-point of the process and to monitor its development. In this feasibility study, we demonstrated the potential of different spectroscopic techniques (1H NMR and IR) coupled with chemometrics analysis in monitoring the hydrolysis of five different industrial grade plant proteins by the enzyme Alcalase. Logarithmic modeling of the PCA (Principal Component Analysis) scores confirmed that they can represent a measurement of the solubilized protein material released and resulted in kinetic parameters describing the suitability of protein sources as substrates for the hydrolysis. This way, we showed that a qualitative evaluation of the degree of hydrolysis is possible using fast at-line technologies and PCA. PMID- 29195948 TI - Effects of soil type and organic fertilizers on fatty acids and vitamin E in Korean ginseng (Panax ginseng Meyer). AB - This study examined the effects of soil type and fertilizer regimes on variations in fatty acids (FAs) and vitamin E (Vit-E) in 6-year-old ginseng roots. We observed significant variation in both FA and Vit-E contents owing to the type and quantity of organic fertilizer used in each soil type during cultivation. Unsaturated FAs were approximately 2.7-fold higher in ginseng than in saturated FAs. Linoleic, palmitic, and oleic acids were the most abundant FAs detected in ginseng roots. Additionally, alpha-tocopherol was the major Vit-E detected. In particular, the increased application of rice straw compost or food waste fertilizer elevated the quantity of nutritionally desirable FAs and bioactive Vit E in ginseng root. Partial least square-discriminant analysis (PLS-DA) score plots showed that soil type might be the main cause of differences in FA and Vit E levels in ginseng. Specifically, the PLS-DA model indicated that palmitic acid is a suitable FA marker in determining whether ginseng plants were grown in a paddy-converted field or an upland field. Moreover, linoleic acid levels were highly correlated with alpha-linolenic acid (r=0.8374; p<0.0001) according to Pearson's correlations and hierarchical clustering analysis. Hence, these preliminary results should prove useful for the reliable production of ginseng containing high phytonutrient quantities according to cultivation conditions. PMID- 29195949 TI - Characterization of binding interaction between rice glutelin and gallic acid: Multi-spectroscopic analyses and computational docking simulation. AB - Many foods contain mixtures of plant dietary proteins and polyphenols, but there is currently a relatively poor understanding of the nature of the interactions between these components. In this study, the interaction of rice glutelin (RG) and gallic acid (GA) was characterized by spectroscopic and molecular docking techniques. The intrinsic fluorescence of RG quenched after the addition of GA, indicating that an interaction occurred. Thermodynamic analyses indicated that the binding process was spontaneous and the main driving forces were hydrogen bonds and van der Waals forces. The surface hydrophobicity of RG decreased with increasing GA. Furthermore, synchronous fluorescence and circular dichroism spectra provided insights into micro-environmental and conformational changes of RG. In particular, there was a reduction of alpha-helix structure and an increase of beta-sheet structure present in RG after the binding interaction. Finally, molecular docking analysis provided a visual representation of a single binding site where GA interacted with specific amino acid residues located in the active site of the RG. PMID- 29195950 TI - Fructooligosaccharides integrity after atmospheric cold plasma and high-pressure processing of a functional orange juice. AB - In this study, the effect of atmospheric pressure cold plasma and high-pressure processing on the prebiotic orange juice was evaluated. Orange juice containing 7g/100g of commercial fructooligosaccharides (FOS) was directly and indirectly exposed to a plasma discharge at 70kV with processing times of 15, 30, 45 and 60s. For high-pressure processing, the juice containing the same concentration of FOS was treated at 450MPa for 5min at 11.5 degrees C in an industrial equipment (Hyperbaric, model: 300). After the treatments, the fructooligosaccharides were qualified and quantified by thin layer chromatography. The organic acids and color analysis were also evaluated. The maximal overall fructooligosaccharides degradation was found after high-pressure processing. The total color difference was <3.0 for high-pressure and plasma processing. citric and ascorbic acid (Vitamin C) showed increased content after plasma and high-pressure treatment. Thus, atmospheric pressure cold plasma and high-pressure processing can be used as non-thermal alternatives to process prebiotic orange juice. PMID- 29195951 TI - Aggregation and rheological behavior of soluble dietary fibers from wheat bran. AB - The present study assesses the aggregation behavior of wheat bran arabinoxylan rich soluble dietary fiber (SDF) fractions with diverse molecular weight and substitution in order to provide useful information to prevent the formation of a block network. In the present work, dynamic and static light scattering, diffusing wave spectroscopy, small amplitude dynamic rheology, atomic force microscopy, and the water-holding and swelling capacities were evaluated to assess the SDF aggregation behavior induced by intrinsic and extrinsic factors. Furthermore, the rheological behavior was explained by the physically cross linked or interpenetrating hydrocolloid network established during SDF self aggregation, dependent on its molecular structure. The results indicated that the SDF fractions exhibiting a high molecular weight and a lower substitution degree and di-substituted ratio led to more significant aggregation due to the formation of disordered tangles coupled with a more solid-like behavior. The obtained information will prove useful for the development of more stable and compatible SDF fractions. PMID- 29195952 TI - The impact of cultivar on polyphenol and biogenic amine profiles in Calabrian red grapes during winemaking. AB - In this study, during winemaking, was evaluated the influence of cultivar on bioactive compounds (organic acids, d-(+)-glucose, d-(-)-fructose, biogenic amines (BAs), anthocyanins, polyphenols and flavonoids) and antioxidant activity of Calabrian (Southern Italy) autochthonous grapes (Arvino, Gaglioppo, Greco Nero, Magliocco Canino, Magliocco Dolce and Nocera). Phenolic compounds increased from grapes to wine for all varieties. Arvino grapevine showed the highest DPPH radical scavenging activity, while a promising inhibition of the lipid peroxidation was observed with Greco Nero grapes. BAs were mostly formed during alcoholic fermentation and Arvino always showed the lowest BAs amounts, while Magliocco Canino generally exhibited the highest. Collectively, the results demonstrated that Calabrian autochthonous grapevines were rich in sugars, organic acids and phenolic compounds thus allowing the production of high quality wines. PMID- 29195953 TI - Effect of glycation derived from alpha-dicarbonyl compounds on the in vitro digestibility of beta-casein and beta-lactoglobulin: A model study with glyoxal, methylglyoxal and butanedione. AB - alpha-Dicarbonyl compounds, which are widely found in common consumed food, are one of the precursors of advanced glycation end products (AGEs). In this study, the effect of glycation derived from glyoxal (GO), methylglyoxal (MGO) or butanedione (BU) on the in vitro digestibility of beta-casein (beta-CN) and beta lactoglobulin (beta-Lg) was investigated. Glycation from alpha-dicarbonyl compounds reduced the in vitro digestibility of studied proteins in both gastric and intestinal stage. In addition, glycation substantially altered the peptides released through gastric and gastrointestinal digestion, as detected by liquid chromatography electrospray-ionization tandem mass spectrometry (LC-ESI-MS/MS). Crosslinked glycation structures derived from BU considerably reduced the sensitivity of glycated beta-Lg towards digestive proteases, albeit to a lesser degree in glycated beta-CN due to its intrinsic unordered structure. By contrast, non-crosslinked AGEs that formed adjacent to enzymatic cleavage sites did not block the enzymatic reaction in several cases, as evidenced by the corresponding digested peptides modified with glycation structures. These findings expand our understanding of the nutritional influence of alpha-dicarbonyl compounds and health impact of relevant dietary AGEs. PMID- 29195954 TI - Dehydration of jambolan [Syzygium cumini (L.)] juice during foam mat drying: Quantitative and qualitative changes of the phenolic compounds. AB - Jambolan [Syzygium cumini (L.)] berries are a popular fruit in Brazil, renowned for their high phenolic compound (PC) content. These PCs have antioxidant, antibacterial, and other characteristics that may be beneficial to human health. The objective of the study was to evaluate the quantitative and qualitative changes of the main phenolic compounds (PCs) (anthocyanins, flavonols, and hydrolysable tannins) in the jambolan fruit, the produced fruit juice, and in the corresponding dehydrated powders obtained by foam mat drying (60, 70, and 80 degrees C) and lyophilization (control). The PCs were analyzed using high performance liquid chromatography with a diode array detection coupled with an electrospray ionization mass spectrometry (HPLC-DAD-ESI-MSn). Juice production resulted in a more pronounced degradation of anthocyanins than flavonols, and facilitated the extraction of hydrolysable tannins. Elevation of the dehydration temperature negatively impacted the anthocyanin content of the products; on the other hand, the flavonols and hydrolysable tannins were more sensitive to oxidation and heating time during dehydration, respectively, than dehydration temperature. In summary, it can be concluded that processing at 70 degrees C is most suitable, in light of the least loss of nutritional quality of the product with processing time. This study directly informs further investigations into preparation of high-quality jambolan fruit products. PMID- 29195955 TI - New insights in integrated response mechanism of Lactobacillus plantarum under excessive manganese stress. AB - As a natural inhabitant of gastrointestinal tract, Lactobacillus plantarum is well known for its health-promoting effects, especially in heavy metal-removal function. The response mechanism integrated physiology and proteomics of Lactobacillus plantarum under excessive manganese stress was systematically performed. More extracellular polymeric substance was secreted, whereas cells preferred to aggregate for resisting manganese stress. The stability of the membrane was maintained by up-regulating the proportion of unsaturated fatty acids, especially cyclopropane fatty acids. The contents of intracellular Asp and Arg, closely related with energy metabolism, decreased under excessive manganese stress. Comparative 2-DE proteomic analysis identified 52 proteins that significantly differed under different levels of manganese stress. The differentially expressed proteins, involved in the carbohydrate, amino acid, stress response and nucleotide metabolisms, were categorized as the crucial components during resisting manganese stress. Moreover, MntH 4 and MntH 5 were identified as the functional elements in regulation of manganese transportation model. The differential expression of six key transporter proteins under different manganese stresses indicated that the MntH 1, 2 and 3 was negatively regulated by MntR, while the regulation of MntH 4 and 5 presented the contrary model. Taken altogether, the study provides new insights into the response mechanism of probiotics to similar environmental stress. PMID- 29195956 TI - Different inoculation methods for semi-dry processed coffee using yeasts as starter cultures. AB - This study evaluates the behavior of Saccharomyces (S.) cerevisiae (CCMA 0543), Candida (C.) parapsilosis (CCMA 0544), and Torulaspora (T.) delbrueckii (CCMA 0684) as starter cultures for semi-dry processed coffee using two inoculation methods: (1) direct inoculation and (2) bucket inoculation. The microbial population was evaluated by plating and real-time polymerase chain reaction (qPCR). The microbial metabolic changes of both bucket and direct inoculation methods during fermentation were evaluated using high performance liquid chromatography (HPLC), and gas chromatography-mass spectrometry (GC-MS). A sensorial test was also carried out. Citric and succinic acids were detected throughout the fermentation period. Chlorogenic acid concentration levels were higher for the bucket method after roasting. Roasted coffee beans also had a higher caffeine concentration, with the exception of the T. delbrueckii (CCMA0684) assay. Acids, pyrazines and pyridines were the main volatile compounds in both green and roasted coffee beans. Coffee cupping results proved that both inoculation methods scored well in terms of coffee quality. The bucket method favored the permanence of the microorganisms during coffee processing, especially the treatment inoculated with S. cerevisiae. PMID- 29195957 TI - Effect of a commercial tannin on the sensorial temporality of astringency. AB - Astringency is a tactile sensation that is generated by a reduction in lubrication in the oral cavity and is generally attributed to the interaction of procyanidins or condensed tannins with salivary proteins. Several factors influence tannin-protein interactions, such as pH, alcohol, sweetness, oxygen and polyphenol content. A scarcely studied factor is the effect of the tannin content on the perception of astringency. The objective of this study was to evaluate the effect of different concentrations of commercial oenological tannin (COT) on the timing of the perception of astringency. For this model, a vinous solution enriched with three concentrations of COT was used. The samples were subjected to a storage period of three months. Additionally, a panel was trained in the perception of astringency in red wines using a method of temporal dominance of sensations (TDS). Astringency descriptors were selected, and the TDS method was used to characterize the astringency. The samples were evaluated using traditional descriptors in TDS and astringency descriptors in TDS. In traditional TDS curves, treatments with higher concentrations of COT showed a higher and more persistent dominance index in the descriptor astringency. Moreover, the stimulus duration variable increased as the COT level increased. Likewise, temporary astringency was dominant over alcohol. For astringency TDS, at low concentrations of COT, the soft and adhesive descriptors were dominant, whereas at high COT concentrations, aggressive and drying were perceived as the dominant descriptors. An increasing concentration of tannin in the vinous solution generated an increased duration and dominance of astringency and reduced the duration of the sensation of alcohol. Finally, the type of perceived astringency was closely related to the tannin concentration. PMID- 29195958 TI - Chlorogenic acids and flavonoid extraction during the preparation of yerba mate based beverages. AB - This study determined the content of chlorogenic acids (CA) and rutin during successive aqueous extraction of yerba mate for terere and chimarrao from four yerba mate types (smooth, native, traditional and coarse ground). Aqueous extracts were prepared aiming to simulate homemade procedure by partially (chimarrao) or completely (terere) immersing the herb into hot (chimarrao) or cold (terere) water (30 times consecutively). The content of CA and rutin in the aqueous extracts was compared to those in methanolic extracts (exhaustive extraction). Terere aqueous extracts gave higher amounts of all phenolic compounds (2.5 to 6 times higher than chimarrao). Among chimarrao, course-ground aqueous extracts had on average 15% more PC (phenolic compounds). By comparing the content in aqueous and methanolic extracts, after 30 successive extractions, on average 14% of the total amount of CA in yerba mate leaves and 9% of rutin were transferred to the chimarrao extracts, whereas terere achieved between 40% and 100% of transference. Thus, this study shows that CA and rutin are continuously extracted during the preparation of aqueous extracts of chimarrao and terere, favoring a high intake of these antioxidant species by consumers.

AB - This study sought to investigate the prevalence of Listeria species (including L. monocytogenes) in a mixed produce and dairy farm and to identify specific meteorological factors affecting Listeria spp. presence. Environmental samples were collected monthly from locations within the mixed farm over 14months and were analyzed for Listeria spp. Meteorological factors were evaluated for their association with the presence of Listeria spp. by using logistic regression (LR) and random forest (RF). The developed LR model identified wind speed and precipitation as significant risk factors (P<0.05), indicating higher wind speed at day 2 prior to sampling and higher average precipitation over the previous 25days before sampling increased the probability of isolation of Listeria spp. from the mixed farm. Results from RF revealed that average wind speed at day 2 prior to sampling and average precipitation in the previous 25days before sampling were the most important factors influencing the presence of Listeria spp., which supported the findings from LR. These findings indicate that the occurrence of Listeria spp. was influenced by wind speed and precipitation, suggesting run-off and wind-driven dust might be possible routes of pathogen transmission in mixed farms. The developed LR and RF models, with robust predictive performances as measured by the area under the receiver operating characteristic curves, can be used to predict Listeria spp. contamination risk in a mixed farm under different weather conditions and can help with the evaluation of farm management practices and the development of control strategies aimed at reducing pre-harvest microbial contamination in a mixed farming system.

AB - This study evaluates the effect of modified lecithin (ML) and sodium caseinate (SC) on the formulation, stability and bioaccessibility of astaxanthin (AXT) loaded oil-in-water (O/W) nanoemulsions. These nanoemulsions were formulated using high-pressure homogenization in four passes at 100MPa. The volume mean diameter (d4,3) of nanoemulsions produced by ML and SC were 163+/-5 and 144+/-12 nm, respectively. The physiochemical stability of nanoemulsions was recorded at 25 degrees C. The nanoemulsions prepared by ML were stable for 30 minutes against a wide range of pH and heating temperatures (60-120 degrees C). However, ML stabilized nanoemulsions showed droplet growth when treated at high NaCl concentrations. In comparison, droplet growth was observed in SC-stabilized nanoemulsions at pH4 and at high temperature treatment. However, SC-stabilized nanoemulsions were stable at high NaCl concentration (500 mM). The SC-stabilized nanoemulsions showed good physical and chemical stability (>70%) after 30 days of storage. The bioaccessibility of AXT in nanoemulsions was significantly higher in ML (33%) than in SC-stabilized nanoemulsions (6%), indicating a strong influence of emulsifier on bioaccessibility. These findings provide valuable information in designing nutritional products such as aqueous based AXT fortified beverages.

AB - There is considerable attention for developing Akkermansia muciniphila as a new therapeutic microbe since it has shown to prevent diet-induced obesity and type 2 diabetes in mice. However, A. muciniphila is sensitive to gastric conditions such as low pH and oxygen. Therefore, we explored the possibility of encapsulating A. muciniphila in a water-in-oil-in-water (W/O/W) double emulsion, to allow for protection during gastric passage and subsequent release in the small intestine. The bacteria were efficiently encapsulated in the inner emulsion droplets and remained entrapped during in vitro gastric digestion. The cells were then released in the simulated intestinal phase of the in vitro system. The viability of encapsulated cells was found to be higher when compared to cells dispersed in buffer, that had been subjected to similar mechanical process as the one conducted to prepare the emulsion systems. Surprisingly, the viability of the processed cells was even higher than that of the cells dispersed in buffer without processing, likely due to shear-induced stress tolerance. To conclude, encapsulation in a double emulsion seems to be a promising strategy to protect A. muciniphila during gastric passage in oral formulations. PMID- 29195962 TI - Safety evaluations and lipid-lowering activity of an Arthrospira platensis enriched diet: A 1-month study in rats. AB - Arthrospira platensis (A. platensis) is worldwide consumed as dietary supplement, but its use in the form of whole biomass for food purposes may raise toxicity concerns. The aim of this study was to preliminarily evaluate the safety of an A. platensis F&M-C256-enriched diet (20% (weight/weight) corresponding to 12g/kg body weight/day), administered to rats for 1month. A. platensis F&M-C256-enriched diet was well tolerated: behavior, body weight, food consumption and growth curves were not affected; no discomfort, no deaths and no physical signs related to the treatment were observed during the administration period; food daily consumption and apparent digestibility were comparable to those of the standard laboratory AIN-76 control diet. Daily water consumption and urine excretion were, on the contrary, significantly higher (27.18+/-1.24 vs 21.53+/-1.68ml and 12.63+/ 0.99 vs 7.00+/-1.29ml respectively), probably because of a slight increase in sodium intake in rats fed A. platensis F&M-C256-enriched diet. Biochemical markers of kidney and liver function were not varied but a significant increase in cholesterol-HDL and a decreased plasma triglycerides level was observed in rats fed A. platensis F&M-C256-enriched diet. These last changes were associated with an increased fecal lipids excretion and liver PPAR-alpha gene expression. These results indicate that A. platensis F&M-C256 is likely safe and well tolerated even at a high dosage in rodents and suggest that it may represent a promising functional food for preventing or even for managing dyslipidemias. PMID- 29195963 TI - Order and session size effects on treatment discrimination: Case study liking for Dulce de Leche. AB - This study aimed to evaluate the implications of the number of samples per panelist in experimental precision and relative efficiency of treatment comparisons when modelling order effects for Dulce de Leche samples using a Sudoku design. Precision is defined as small variance and relative efficiency is defined as smaller variance than other alternative. Both are related to increasing discrimination power. A series of 8 Sudoku 16*16 squares being 4 randomized independently and 4 others in the reverse order, was designed to allow a linear model fitting to experiments of different sizes (orders 1 to 4, 1 to 8, 1 to 12 and 1 to 16). Data from 112 panelists were kept. Responses were recorded using a nine-point hedonic scale. Data was analyzed using a mixed linear model panelist, order and treatment (sample) effects. Analysis has shown a pronounced order effect, showing a first sample effect overestimation. Moreover, it was noted that order effect was rather evidenced in the first four orders, making for a relatively more precise experiment than the ones using remaining samples. Therefore, the use of Sudoku can be a convenient strategy to organize smaller testing sessions that could result in efficient experiments, with small variance of the estimated averages or effects and needing a lot less panelists to make a design as efficient as the large one used. Moreover, Sudoku can also inspire an efficient design that allows different test sessions.

AB - Increasing the content in bioactive phenolics in the eggplant (Solanum melongena) fruit is of interest, but may result in enhanced browning. We evaluated six varieties of S. melongena, 22 accessions of wild related species and 42 interspecific hybrids between cultivated eggplant and wild relatives for phenolics content, fruit flesh colour, polyphenol oxidase (PPO) activity, and fruit flesh browning. Wild relatives generally had a higher content in phenolics and a broader range of variation than cultivated eggplant. Chlorogenic acid was the predominant (>65.0%) phenolic acid in cultivated eggplant and its primary genepool wild ancestor S. insanum, while for the other wild species on average represented <50% of the chromatogram peak area. Fruit flesh colour was lighter in S. melongena than in the wild species, while PPO activity and browning was much higher in wild species of the secondary and tertiary genepools. Interspecific hybrids between S. melongena and S. insanum were intermediate in their characteristics, while those with secondary and tertiary genepool species were more similar to the wild species. No significant correlations were found between total phenolics or chlorogenic acid contents and fruit flesh browning, but PPO activity was correlated to both the degree of browning (r=0.404) and colour difference (r=0.458). The results indicate that wild species can contribute to improving the bioactive properties of eggplant without affecting negatively fruit flesh colour and browning. PMID- 29195965 TI - Effect of atmospheric cold plasma (ACP) with its extended storage on the inactivation of Escherichia coli inoculated on tomato. AB - The study investigated the efficacy of atmospheric cold plasma (ACP) treatment on inactivation of E. coli load during extended storage period of 48h at both the temperatures of refrigeration (4 degrees C) as well as room (25 degrees C). The tomato samples were spot inoculated with E. coli and exposed to ACP at 15 and 60kV for 5, 10, 15, and 30min followed by their storage at 4 degrees C and 25 degrees C. The highest log reduction of 6logCFUmL-1 was achieved in population of E. coli after 15min of ACP treatment at 60kV, which was sustained up to storage duration of 48h at both the temperatures. Furthermore, significant reduction in E. coli was found at plasma treatment of 60kV in comparison to 15kV. The inactivation of E. coli was significantly (p<0.01) affected by combination of treatment higher voltage at extended treatment time, however, treatment time with prolonged storage of sealed ACP treated tomato was observed as a key factor in reduction of E. coli. In addition, investigation of E. coli exposed tomato surface was done using scanning electron microscopy that clearly showed the breakdown of cell cover of E. coli as a consequence of ACP. The study predicts the promising potential of the technique in sanitization of vegetables that are eaten raw like tomato. PMID- 29195966 TI - Thermal stability of reconstituted milk protein concentrates: Effect of partial calcium depletion during membrane filtration. AB - Milk protein concentrate (MPC) powders are increasingly utilized in manufacturing of protein fortified beverages. Thermal stability of the protein dispersions is of significant importance in such applications. It is known that a decrease in pH can induce partial dissociation of casein micelles and modify the natural equilibrium of calcium and phosphate between the micelles and the serum phase. The presence of soluble casein may improve the rehydration properties of MPC powders, and may impact their thermal stability. The objective of this work was to investigate the effects of partial acidification of milk prior to ultrafiltration on the heat stability of reconstituted MPC dispersions. Milk protein concentrate powders were prepared from skim milk acidified to pH6.0 by addition of glucono-delta-lactone, and then concentrated using ultrafiltration (UF) and diafiltration (DF). The heat stability of the reconstituted MPC dispersions was studied, by determining heat coagulation time, particle size, turbidity, viscosity, soluble and colloidal calcium and phosphate, and non sedimentable casein both before and after heating at 120 degrees C. Reconstituted MPC powders made with partially acidified skim milk contained lower soluble calcium and phosphate and exhibited very poor thermal stability compared to MPC powders made with skim milk at its natural pH. The thermal stability of the acidified MPC dispersions was not only recovered by restoration of pH and the serum composition through dialysis against skim milk, but it was improved compared to control MPC dispersions. All dialyzed samples had comparable pH, protein content and calcium and phosphate concentration, but the structure of the casein micelles was altered, causing differences in the type of soluble aggregates. It was concluded that the integrity of the casein micelles and the amount of dissociated, non-sedimentable caseins play a major role in determining the thermal stability of the MPC dispersions. PMID- 29195967 TI - Thermal effusivity measurement of conventional and organic coffee oils via photopyroelectric technique. AB - In this work, oil samples extracted from organic and conventional coffee beans were studied. A fatty acids profile analysis was done using gas chromatography and physicochemical analysis of density and acidity index to verify the oil purity. Additionally, Mid-Infrared Fourier Transform Photoacoustic Spectroscopy (FTIR-PAS) aided by Principal Component Analysis (PCA) was used to identify differences between the intensities of the absorption bands related to functional groups. Thermal effusivity values between 592+/-3 and 610+/-4Ws1/2m-2K-1 were measured using the photopyroelectric technique in a front detection configuration. The acidity index was between 1.11 and 1.27% and the density changed between 0.921 and 0.94g/mL. These variables, as well as the extraction yield between 12,6 and 14,4%, showed a similar behavior than that observed for the thermal effusivity, demonstrating that this parameter can be used as a criterion for discrimination between oil samples extracted from organic and conventional coffee beans. PMID- 29195968 TI - Sensory characterization of the astringency of commercial Uruguayan Tannat wines. AB - Astringency is one of the most important characteristics that define the quality of red wine, and is of particular relevance for Tannat, Uruguayan emblematic red wine variety. Astringency is a time-dependant and complex sensory characteristic, related to several sensations, or sub-qualities, that can be simultaneously perceived. The aim of the present study was to obtain a sensory characterization of the astringency of commercial Uruguayan Tannat wines. Forty samples with different characteristics in terms of vintage, price segment and aging in oak barrels were assessed by a panel of 9 trained assessors. Total astringency intensity was evaluated using time-intensity (TI), while astringency sub qualities were described using a check-all-that-apply (CATA) question composed of sixteen terms. TI and the CATA question provided different information on the astringency of Tannat wines. Regarding global astringency, samples mainly differed in intensity-related parameters rather than in the development of astringency over time, although the variability was moderate. A wide range of sub qualities, from silky and velvety to harsh and aggressive were used to describe the astringency of the evaluated wines. Four groups of samples with different astringency characteristics were identified, but this sorting was not related to vintage, price segment or aging in oak barrels. Further research is necessary to better understand how astringency characteristics are influenced by production variables, and to understand their relationship to consumers' and experts' perceived quality of Tannat wines. PMID- 29195969 TI - Rapid methodology via mass spectrometry to quantify addition of soybean oil in extra virgin olive oil: A comparison with traditional methods adopted by food industry to identify fraud. AB - Fast and innovative methodology to monitors the addition of soybean oil in extra virgin olive oil was developed employing ESI-MS with ionization operating in positive mode. A certified extra virgin olive oil and refined soybean oil samples were analyzed by direct infusion, the identification of a natural lipid marker present only in soybean oil (m/z 886.68 [TAG+NH4]+) was possible. The certified extra virgin olive oil was purposely adulterated with soybean oil in different levels (1, 5, 10, 20, 50, 70, 90%) being possible to observe that the new methodology is able to detect even small fraud concentration, such as 1% (v/v). Additionally, commercial samples were analyzed and were observed the addition of soybean oil as a common fraud in this segment. This powerful analytical method proposed could be applied as routine analysis by control organization, as well as food industries, considering its pronounced advantages; simplicity, rapidity, elevated detectability and minor amounts of sample and solvent consumed. PMID- 29195970 TI - Protection of resveratrol against the photodecomposition of folic acid and photodecomposition-induced structural change of beta-lactoglobulin. AB - Folic acid is a synthetic form of the B-group vitamin known as folate and essential for a variety of physiological processes. However, it decomposes under UV irradiation, causing indirect oxidation and structural change of protein. In this study, the protective effect of resveratrol against the photodecomposition of folic acid and its caused protein structural change was investigated by using fluorescence and absorbance spectroscopy, high performance liquid chromatography and ABTS assay. It was found that resveratrol could inhibit the folic acid decomposition and control the decomposition process, depending on the polyphenol concentration and addition time. Transformation of resveratrol was accelerated by photodecomposition of folic acid. Antioxidant activity of resveratrol was important for the protective effect. Moreover, resveratrol could also inhibit the unfolding of beta-lactoglobulin caused by the folic acid decomposition by using circular dichroism. PMID- 29195971 TI - Effects of dietary replacement of fishmeal by mealworm meal on muscle quality of farmed shrimp Litopenaeus vannamei. AB - This study investigated the muscle quality of the shrimp Litopenaeus vannamei fed on a diet containing different proportions of mealworm meal (MW) (0, 25, 50, 75 and 100%) as a substitute for fishmeal, which is the normal diet used in shrimp commercial production. The proximate composition, fatty acid profile, colour and texture of the shrimps were evaluated. Moisture, protein, and ash content of shrimp muscle were not significantly altered when fishmeal was replaced by MW (p>0.05). However, the replacement resulted in a linear increase in lipid content (p<0.05). The fatty acid composition of the experimental diets directly mirrored the fatty acid composition of shrimp muscle. The absence of long-chain polyunsaturated fatty acids in MW composition resulted in a linear decrease in eicosapentaenoic and docosahexaenoic fatty acids in shrimp muscle with increasing levels of MW in the diet. The n-3/n-6 ratio ranged from 0.50 to 0.67. Colour and firmness were unchanged between the treatments. Although the use of MW as a fishmeal substitute in L. vannamei diets has affected the lipid and fatty acid composition of shrimp muscle, from a human nutritional perspective, the lipid content of the shrimps is considered low and the n-3/n-6 ratio remained within the human dietary requirements. Therefore the use of a mealworm diet for shrimp production is a viable alternative to increasingly expensive fishmeal based diets. PMID- 29195972 TI - Impact of phenylalanine and urea applications to Tempranillo and Monastrell vineyards on grape amino acid content during two consecutive vintages. AB - Nitrogen plays a key role in the fermentation and secondary metabolites formation. The aim was to study the influence of vine nitrogen applications on grape amino acid composition. Nitrogen sources applied to Tempranillo and Monastrell grapevines were phenylalanine and urea, during two seasons. Results showed that the application of these compounds had little effect on grape amino acid composition, regardless of variety and vintage. This could be due to the fact that vineyards did not present nitrogenous requirements. Thus, variety was the determining factor in Asp, Glu, Gln, Cit, Met, Gly, Gaba, Val, Ile, and Leu while season was the factor that most affected Thr, Arg, Ala, and Lys due its implication on berry ripening. The concentration of the remaining amino acids was influenced by two or three of the factors studied. Therefore, when the vineyard has adequate nitrogen nutritional status, grape amino acid content was determined by variety and vintage. PMID- 29195973 TI - Microstructure and physicochemical properties reveal differences between high moisture buffalo and bovine Mozzarella cheeses. AB - Mozzarella cheese is a classical dairy product but most research to date has focused on low moisture products. In this study, the microstructure and physicochemical properties of both laboratory and commercially produced high moisture buffalo Mozzarella cheeses were investigated and compared to high moisture bovine products. Buffalo and bovine Mozzarella cheeses were found to significantly differ in their microstructure, chemical composition, organic acid and proteolytic profiles but had similar hardness and meltability. The buffalo cheeses exhibited a significantly higher ratio of fat to protein and a microstructure containing larger fat patches and a less dense protein network. Liquid chromatography mass spectrometry detected the presence of only beta-casein variant A2 and a single beta-lactoglobulin variant in buffalo products compared to the presence of both beta-casein variants A1 and A2 and beta-lactoglobulin variants A and B in bovine cheese. These differences arise from the different milk composition and processing conditions. The differences in microstructure and physicochemical properties observed here offer a new approach to identify the sources of milk used in commercial cheese products. PMID- 29195974 TI - Colorimetric study of malvidin-3-O-glucoside copigmented by phenolic compounds: The effect of molar ratio, temperature, pH, and ethanol content on color expression of red wine model solutions. AB - In the recent research, the copigmentations of malvidin-3-O-glucoside with eight types of phenolic copigments have been investigated. The influence of the pigment/copigment molar ratio, the reaction temperature, the pH and the ethanol content of solutions has been examined. The results showed that the copigmentation effect was dependent on not only the particular structures of the phenolic compounds but also the factors of the reaction systems. The increase of the copigment concentration can strengthen the copigmentation effect, improve the solution color, and enhance the red-purple features. Different temperatures had different influences on the copigmentation reactions. The destruction of the copigmentation complexes can result in the hypsochromic shift of the reaction solution when the temperature was higher than 20 degrees C. The bathochromic shift of the solution gradually progressed with the increase of the pH value. A significant copigmentation feature was spotted when pH reached 3.0, which demonstrates obvious red-purple characterization. The addition of the ethanol weakened the copigmentation effect. According to measurement through color analysis, it was found that the color differences caused by ethanol in red wine were typically attributed to quantitative changes. Remarkably, all of the above delicate color deviations caused by the structural or environmental factors can be precisely and conveniently depicted via the CIELAB space analysis. PMID- 29195975 TI - Exploring mouthfeel in model wines: Sensory-to-instrumental approaches. AB - Wine creates a group of oral-tactile stimulations not related to taste or aroma, such as astringency or fullness; better known as mouthfeel. During wine consumption, mouthfeel is affected by ethanol content, phenolic compounds and their interactions with the oral components. Mouthfeel arises through changes in the salivary film when wine is consumed. In order to understand the role of each wine component, eight different model wines with/without ethanol (8%), glycerol (10g/L) and commercial tannins (1g/L) were described using a trained panel. Descriptive analysis techniques were used to train the panel and measure the intensity of the mouthfeel attributes. Alongside, the suitability of different instrumental techniques (rheology, particle size, tribology and microstructure, using Transmission Electron Microscopy (TEM)) to measure wine mouthfeel sensation was investigated. Panelists discriminated samples based on their tactile-related components (ethanol, glycerol and tannins) at the levels found naturally in wine. Higher scores were found for all sensory attributes in the samples containing ethanol. Sensory astringency was associated mainly with the addition of tannins to the wine model and glycerol did not seem to play a discriminating role at the levels found in red wines. Visual viscosity was correlated with instrumental viscosity (R=0.815, p=0.014). Hydrodynamic diameter of saliva showed an increase in presence of tannins (almost 2.5-3-folds). However, presence of ethanol or glycerol decreased hydrodynamic diameter. These results were related with the sensory astringency and earthiness as well as with the formation of nano complexes as observed by TEM. Rheologically, the most viscous samples were those containing glycerol or tannins. Tribology results showed that at a boundary lubrication regime, differences in traction coefficient lubrication were due by the presence of glycerol. However, no differences in traction coefficients were observed in presence/absence of tannins. It is therefore necessary to use an integrative approach that combines complementary instrumental techniques for mouthfeel perception characterization. PMID- 29195976 TI - The effect of CaCl2 marination on the tenderizing pathway of goose meat during conditioning. AB - In order to figure out the effect of CaCl2 on the tenderizing pathway of goose meat, breast muscles of thirty-two Eastern Zhejiang White Geese were divided into three treatments: the control, 150 and 300mM CaCl2. Shear force, myofibrillar fraction index (MFI), actin filaments and F-actin, G-actin and tropomodulins (Tmods) levels were investigated during 168h. Results showed that 300mM treatment had lower shear force at 48, 96 and 168h and higher MFI at 24, 48, 96 and 168h than the control. The rate of actin filaments disruption, the decrease of F actin, the degradation of Tmods, the increase of G-actin in 300mM treatment was faster than 150mM treatment; the rate in the control was the slowest among treatments. CaCl2 accelerated the transformation of F-actin into G-actin. We concluded that CaCl2 tenderized goose meat by depolymerizing actin filaments and cleaving Tmods. PMID- 29195977 TI - Study the effects of drying processes on chemical compositions in daylily flowers using flow injection mass spectrometric fingerprinting method and chemometrics. AB - Daylily flowers is an important vegetable in eastern Asia, widely used in many dishes. Daylily flowers are usually sold in dried forms in the supermarkets. There are a few method for processing fresh daylily flowers, however, no study has been conducted to analyze the effects of the processing methods in the composition of final products. In the present study, a flow-injection mass spectrometric fingerprinting (FIMS) method in combination with principal component analysis (PCA) was used to differentiate two species of daylily flowers (Mengzi and Chongli) with three different treatments (vacuum freeze drying, solar drying and hot-air drying treatments) for each. The results showed the fast and simple FIMS method could successfully differentiate between species (raw material) and treatments among each species. However, the two species could not be discriminated very well after being processed in hot-air drying treatment. The difference in chemical profiles of species and treatments were discussed. PMID- 29195978 TI - Merging vibrational spectroscopic data for wine classification according to the geographic origin. AB - The wine making procedure is no longer a secret and it is nowadays well described and repeated around the world. Nevertheless, wines present unique features, strongly associated with their geographic origin. Classification systems were developed to catalogue wines according to the provenance, and are currently established by official authorities in order to ensure wine authenticity. The use of near-infrared (NIR), mid-infrared (MIR) and Raman spectroscopy for tracing the origin of wine samples, has been reported with different levels of success. This work evaluated and compared the performance of these techniques, as well as their joint use, in terms of geographic origin classification. NIR, MIR and Raman spectra of wine samples belonging to four Portuguese wine regions (Vinhos Verdes, Lisboa, Acores and Tavora-Varosa) were analyzed by partial least squares discriminant analysis (PLS-DA). Results revealed the better suitability of MIR spectroscopy (87.7% of correct predictions) over NIR (60.4%) and Raman (60.8%). The joint use of spectral sets did not improve the predictive ability of the models. The best models were achieved by combining MIR and NIR spectra resulting in 86.7% of correct predictions. Multiblock partial least squares (MB-PLS) models were developed to further explore the combination of spectral data. Although these models did not improve the percentage of correct predictions, they demonstrated the higher contribution of MIR spectroscopic data, in the development of the models. PMID- 29195979 TI - Analysis of the bacterial microbiome in the small octopus, Octopus variabilis, from South Korea to detect the potential risk of foodborne illness and to improve product management. AB - The small octopus (Octopus variabilis) is a popular seafood in many countries including South Korea. Because it is often consumed uncooked, the microorganisms in it often cause food poisoning. Therefore, analyzing the microbiome of the small octopus can help to understand the risk of food poisoning and manage octopus products better. A total of 40 small octopuses were collected from four sites in November and August. The microbiota was analyzed using Illumina Miseq sequencing, and the amount of bacteria was quantified by real-time PCR. In addition, we analyzed the influence of Vibrio vulnificus infection on the microbiome of the small octopus through artificial infection experiments. Bacteroidetes was the predominant phylum in August, and Proteobacteria was predominant in November. The composition of the microbiota in octopus depended on sampling region and season. The potential risk of foodborne illness from small octopus consumption might be higher in August than in November due to the abundance of potential pathogens. In the infection experiment, the proportion of V. vulnificus increased only at 27 degrees C. The composition and functional gene profiles of the microbiota varied in a similar manner between non-infected and infected samples over time at the same temperature. These results indicated that the indigenous microbiota in small octopus could inhibit colonization by V. vulnificus during storage. Although further studies are necessary to clarify these results, our results could help us better understand food poisoning through octopus ingestion and manage products. PMID- 29195980 TI - Comparative stability and efficacy of selected chlorine-based biocides against Escherichia coli in planktonic and biofilm states. AB - Microbial contamination is an unavoidable problem in industrial processes. Sodium hypochlorite (SH) is the most common biocide used for industrial disinfection. However, in view of the current societal concerns on environmental and public health aspects, there is a trend to reduce the use of this biocide as it can lead to the formation of organochlorinated carcinogenic compounds. In this work the efficacy of SH was assessed against Escherichia coli in planktonic and biofilm states and compared with three alternative chlorine-based biocides: neutral electrolyzed oxidizing water (NEOW), chlorine dioxide (CD) and sodium dichloroisocyanurate (NaDCC). The planktonic tests revealed that SH had the fastest antimicrobial action, NaDCC exhibited the highest antimicrobial rate and NEOW caused the highest antimicrobial effects. Additionally, NEOW was the biocide that allowed the highest formation of reactive oxygen species (ROS). In biofilm control, NEOW and CD were the most efficient biocides causing 3.26 and 3.20 log CFU.cm-2 reduction, respectively. In terms of stability for chlorine depletion, NEOW had the longest decay time for chlorine loss (70days at 5 degrees C) and the lowest chlorine loss rate (0.013ppm.min-1 at 5 degrees C). CD and NaDCC had equivalent stability. The overall results demonstrated NEOW as a good alternative to SH due to its higher antimicrobial effects and lower chlorine depletion over time. PMID- 29195981 TI - Stress adaptation has a minor impact on the effectivity of Non-Thermal Atmospheric Plasma (NTAP) against Salmonella spp. AB - This study was aimed at studying the influence of gas composition (air and nitrogen) at different flow rates (5, 10 and 15Lm-1) and stress adaptation (growth under a wide range of temperatures [10-45 degrees C] and acid conditions [up to pH4.5, using different organic acids] or short-term exposure to acid, cold or heat stress shocks) on the inactivation by Non-Thermal Atmospheric Plasma (NTAP) of S. Typhimurium CECT 443 and S. Enteritidis CECT 4300. Results obtained evidence that microbial inactivation was significantly higher when air was used for NTAP treatments. D-values obtained using air ranged from 0.86 to 2.43min and 0.90 to 1.69min for S. Typhimurium and S. Enteritidis, respectively, while those obtained using nitrogen ranged from 3.08 to 5.75min and 2.28 to 5.54min, respectively. Microbial inactivation also increased with increasing flow rates, although differences were not statistically significant in all cases. Growth temperature and pH or exposure to acid, cold or heat stress shocks had a minor impact on NTAP resistance. Indeed, D-values obtained under the different stress adaptation scenarios were not significantly different from those obtained for non adapted control cultures (1.38+/-0.39 for S. Typhimurium and 1.23+/-0.36 for S. Enteritidis), with the exception of cells grown at 10 degrees C, which were significantly more sensitive to NTAP, with D-values of 0.68+/-0.11 and 0.45+/ 0.10min, respectively, for S. Typhimurium and S. Enteritidis. These findings suggest that adaptive responses triggered by exposure to acid, cold or heat stresses, already described in the past for these two Salmonella strains, do not provide protection against NTAP treatments, which allows us to conclude that NTAP may be a first-choice technology to be included into food processing schemes following a hurdles technology approach in combination with acidification, mild heating or refrigeration. PMID- 29195982 TI - High resolution mass approach to characterize refrigerated black truffles stored under different storage atmospheres. AB - Freshly harvested Tuber melanosporum samples were packed and stored at 4 degrees C under reduced atmospheric pressure or modified atmosphere for four weeks. Multivariate analysis was employed to correlate the antioxidant power of the ethanolic extracts of the samples with the chemical composition determined by high resolution mass spectrometry. High performance liquid chromatography coupled with a coularray detector was applied to select the chemical species associated with the antioxidant power. Four classes of chemical compounds were investigated in more detail by a targeted approach: derivatives of glutathione, adenine (such as S-adenosyl-homocysteine), oxidized linoleic acid and ergosterol. Adducts containing glutathione and adenine with oxidized linoleic acid were observed in TM for the first time and can be considered markers of freshness of the product. S-adenosyl-homocysteine, the acetyl-carnitine adduct with cysteinyl-glycine and several oxidized linoleic acid derivatives were among the markers of degradation. PMID- 29195983 TI - Comparative analysis of the volatile composition of honeys from Brazilian stingless bees by static headspace GC-MS. AB - The volatile composition of honeys produced by eight species of stingless bees collected in three municipalities in the state of Parana (Brazil) was compared by combining static headspace GC-MS and chemometrics methods. Forty-four compounds were identified using NIST library and linear retention index relative to n alkanes (C8-C40). Linalool derivatives were the most abundant peaks in most honeys regardless geographical or entomological origin. However, Principal Component Analysis discriminated honeys from different geographical origins considering their distinctive minor volatile components. Honey samples from Guaraquecaba were characterized by the presence of hotrienol while those from Cambara showed epoxylinalol, benzaldehyde and TDN as minor discriminating compounds. Punctual species such as Bora showed similar fingerprints regardless geographical origin, with ethyl octanoate and ethyl decanoate as characteristic intense chromatographic peaks, which may suggest a specialized behavior for nectar collection. Discriminant Analysis allowed correct geographic discrimination of most honeys produced in the three spots tested. We concluded that volatile profile of stingless bee honeys can be used to attest authenticity related to regional origin of honeys. PMID- 29195984 TI - Spatial (cap & stipe) metabolomic variations affect functional components between brown and white beech mushrooms. AB - The beech mushrooms have customarily been revered by oriental societies for their nutritional and health benefits. We explored the mass spectrometry (MS) based spatial metabolomic variations between parts (cap and stipe) of two beech mushroom strains (brown and white). The principal component analysis (PCA) revealed their distinct primary (cap and stipe: PC1, 25.5%; strains: PC2, 12.5%) and secondary (cap and stipe: PC1, 10.3%; strains: PC2, 7.6%) metabolite patterns. The caps were rich in amino acids, fatty acids, and N-acetylglucosamine with higher protein and nitrogen contents. The stipes had abundant beta-glucans, malic acid, and fructose. The discriminant secondary metabolites, especially, hypsiziprenols were higher in caps from brown strains. A fatty acid derivative, azelaic acid, was abundant in white strains (cap>stipe). We established a positive correlation for the cytotoxic activities of hypsiziprenols against ACHN cells. These spatial inter-strain metabolomic distinctions are potentially helpful for mushroom selection and improvement. PMID- 29195985 TI - What are the cultural effects on consumers' perceptions? A case study covering coalho cheese in the Brazilian northeast and southeast area using word association. AB - The aim of this study was to investigate the effects of regional diversity aspects related to consumers' perceptions of coalho cheese, with Brazilian Northeast and Southeast consumers (n=400, divided equally in each area) using Word Association (WA) task. Different perceptions were detected for both Northeast and Southeast consumers, and among 17 categories elicited for describing coalho cheese, only 7 categories (positive feeling, social aspects, sensory characteristic, dairy product technology, negative feeling, and lack of quality standard) presented significant differences in the frequency of mention according to chi-square per cell approach. The application of the discriminant technique Partial Least Square Discriminant Analysis (PLS-DA) indicated that the categories "Social", "Accompaniment", "Manufacturing method" were the main responsible for differentiating consumers' perceptions of both areas. Overall, the main dimensions involved in the consumers' perceptions of coalho cheese from different Brazilian regions were identified, thus obtaining comprehensive insights that can be used as a guideline for coalho cheese producers to develop marketing strategies considering the intra-cultural differences. PMID- 29195986 TI - Comparison of non-volatile umami components in chicken soup and chicken enzymatic hydrolysate. AB - Umami taste is an important part to the taste of chicken. To isolate and identify non-volatile umami compounds, fractions from chicken soup and hydrolysate were prepared and analyzed. Amino acids were analyzed by amino acid analyzer. Organic acids and nucleotides were determined by ultra-performance liquid chromatography. Separation procedures utilizing ultrafiltration, Sephadex G-15 and reversed-phase high-performance liquid chromatography were used to isolate umami taste peptides. Combined with sensory evaluation and LC-Q-TOF-MS, the amino acid sequences of 12 oligopeptides were determined. The amount of taste compounds was higher in chicken enzymatic hydrolysate than that of chicken soup. Eight oligopeptides from chicken enzymatic hydrolysate were identified, including Ala-Asp, Ala-Met, His Ser, Val-Glu, Ala-Glu, Asp-Ala-Gly, Glu-Asp and Ala-Glu-Ala. Four oligopeptides from chicken soup were identified, including Val-Thr, Ala-His, Ala-Phe and Thr Glu. PMID- 29195987 TI - Physiological comparability of the harmonized INFOGEST in vitro digestion method to in vivo pig digestion. AB - Recently, a static in vitro digestion (IVD) protocol was published by Minekus and coworkers (Minekus et al., 2014) within the COST INFOGEST network. The protocol, concentrating on physiological enzyme activities had the main goal to improve the comparability of experimental data between labs. The protocol was validated in several inter-laboratory studies using skim milk powder (SMP) and indeed demonstrated improved harmonization compared with previous experiments with individual IVD protocols (Egger et al., 2016). Although the enzyme activities and salt concentrations of the harmonized protocol are based on available human in vivo data, confirmation of the protocol's physiological relevance has been lacking until now. The main goal of the study was therefore to compare the harmonized IVD protocol with data from in vivo digestion. Towards this aim, an in vivo pig experiment with the same SMP as used for the validation of the IVD protocol was performed followed by a comparison of protein hydrolysis between in vivo and in vitro results. Protein hydrolysis at different levels was analyzed with gel electrophoresis, mass spectrometry, high performance liquid chromatography, and spectrophotometric o-phthaldialdehyde determination of free amino acids. Principle component analysis was used for graphical data comparison. Milk proteins detected after gastric IVD corresponded to gastric and duodenal in vivo samples and intestinal IVD samples corresponded to distal jejunal in vivo samples. Peptides identified after the gastric phase of IVD, correlated with in vivo gastric samples (r=0.8) and intestinal IVD peptides correlated best with in vivo samples collected from the median jejunum (r=0.57). Free amino acids were in both systems mainly released during the intestinal phase of digestion. Protein hydrolysis in the harmonized IVD was similar to in vivo protein hydrolysis in pigs at the gastric and intestinal endpoints. Therefore, the harmonized static in vitro protocol is suited to study protein hydrolysis at these endpoints. PMID- 29195988 TI - Recent advances in microencapsulation of natural sources of antimicrobial compounds used in food - A review. AB - Food safety and microbiological quality are major priorities in the food industry. In recent years, there has been an increasing interest in the use of natural antimicrobials in food products. An ongoing challenge with natural antimicrobials is their degradation during food storage and/or processing, which reduces their antimicrobial activity. This creates the necessity for treatments that maintain their stability and/or activity when applied to food. Microencapsulation of natural antimicrobial compounds is a promising alternative once this technique consists of producing microparticles, which protect the encapsulated active substances. In other words, the material to be protected is embedded inside another material or system known as wall material. There are few reports in the literature about microencapsulation of antimicrobial compounds. These published articles report evidence of increased antimicrobial stability and activity when the antimicrobials are microencapsulated when compared to unprotected ones during storage. This review focuses mainly on natural sources of antimicrobial compounds and the methodological approach for encapsulating these natural compounds. Current data on the microencapsulation of antimicrobial compounds and their incorporation into food suggests that 1) encapsulation increases compound stability during storage and 2) encapsulation of antimicrobial compounds reduces their interaction with food components, preventing their inactivation.

AB - Pectins can modulate the biological responses interacting directly with immune cells. The observed responses can strongly be affected by polysaccharide structural features. We analyzed the intrinsic activation capacity of native and modified sweet pepper pectin on cytokine secretion by THP-1 macrophages as well as compare their effects in the presence of lipopolysaccharide. Modified pectin was obtained by partial acid hydrolysis which promoted the removal of side chains as well as the reduction of molecular weight and the degree of methyl esterification of native pectin. The results showed that both fractions had no effect on THP-1 viability. Native pectin at 300MUg/mL increased TNF-alpha, IL 1beta and IL-10 cytokine secretion by THP-1 macrophages. However, in the presence of lipopolysaccharide, it can attenuate the inflammatory response by reducing the production of the pro-inflammatory cytokines TNF-alpha and IL-1beta and increasing the anti-inflammatory cytokine IL-10, as well as decreasing the TNF alpha/IL-10 and IL-1beta/IL-10 ratios. The structural modifications caused by acid hydrolysis affected the intrinsic activation capacity of native pectin to modulate the cytokines secretion. These results indicate that degree of methyl esterification, molecular weight and presence of side chains are important structural features of pectins involved in the modulation of cytokine secretion by THP-1 macrophages.

AB - The search for compounds with functional properties from natural sources has grown in recent years as people have developed healthier habits. Therefore, the aim of this study was to evaluate the extraction of bioactive compounds from various parts of unripe genipap fruit (Genipa americana L.) by using pressurized ethanol to verify which part of the fruit provides the greatest recovery of the iridoids genipin and geniposide. Two process variables were studied: temperature (50 and 80 degrees C) and pressure (2, 12 and 20 bar). The whole fruit and the peel, mesocarp, endocarp, endocarp+seeds and seeds of the fruit were studied. The endocarp presented with the highest recovery of genipin (48.6+/-0.6mg/g raw material) and the extraction from the mesocarp allowed a greater recovery of geniposide (59+/-1mg/g raw material). The highest values of total phenolic content were obtained with mesocarp extracts. The endocarp and mesocarp extracts presented the highest antioxidant activity as measured by FRAP and DPPH. These results are promising and support the use of unripe genipap fruit as a source of iridoids and natural antioxidants.

AB - Legumes are an important protein source in developing countries and their flours represent an attractive alternative for the manufacture of gluten free products. In the present study, 4 kidney bean varieties (Alubia, Pallar, Black and Red beans) commonly cultivated in northwestern Argentina, were milled and spontaneously fermented in order to isolate and select autochthonous lactic acid bacteria (LAB) with relevant technological and functional properties for usage as starter cultures. Twelve doughs were fermented with daily back-slopping at 37 degrees C for 6days and evolution of total mesophiles, lactic acid bacteria, and yeasts and molds populations were followed by plate counting. A combination of phenotypic and genotypic methods including (GTG)5-based PCR fingerprinting and 16S rRNA gene sequencing were used to differentiate and identify the isolated LAB to species level. LAB counts ranged from around 0.89+/-0.81 to 8.74+/ 0.03logcfu/g with a pH decline from 6.4 to 3.9 throughout fermentation. Four genera and nine species of LAB: Enterococcus durans, E. faecium, E. mundtii, E. casseliflavus; Lactobacillus rhamnosus, Lactococcus garvieae, Weissella cibaria and W. paramesenteroides were found on kidney beans. Twenty five LAB strains were assessed for their abilities to grow on kidney bean extracts, acidifying capacities (pH and acidification rates), amylolytic, proteolytic, tannase and gallate decarboxylase activities as well as pathogens inhibition by antimicrobials. Based on these properties E. durans CRL 2178 and W. paramesenteroides CRL 2182 were inoculated singly and combined in Alubia kidney bean flour and fermented for 24h at 37 degrees C. LAB strains were beneficial for removing trypsin inhibitors and tannins from sourdoughs and for improving amino acids and phenolics contents, increasing the antioxidant activities of kidney bean matrices. Selected strains have potential as starter cultures for obtaining fermented bean products with high nutritional and functional quality.

AB - Several Cronobacter species are opportunistic pathogens that cause infections in humans. This study evaluated the phenotypic characteristics of 57 Cronobacter strains (C. sakazakii n=41, C. malonaticus n=10, C. dublinensis n=4, and C. muytjensii n=2) isolated from food (n=54) and clinical specimens (n=3) in Brazil. These strains included sequence types (ST): ST395-ST398, ST402, ST413 and ST433 ST439, isolated from food samples, and three C. malonaticus clinical strains previous isolated from an outbreak which were ST394 (n=1) and ST440 (n=2). Strains were tested for capsule production, biofilm formation, protease activity, hemolytic activity, cell-cell aggregation, and desiccation resistance. Capsule formation was observed with all Cronobacter strains. Forty-four (77.2%) strains showed proteolytic activity on milk agar. All strains showed beta-hemolysis against erythrocytes from guinea pig, horse and rabbit. Using erythrocytes from sheep, the majority of strains (53/57; 92.9%) showed alpha-hemolysis and the remaining, beta-hemolysis. All Cronobacter strains produced weak biofilms in microtiters polystyrene plates, which were independent of temperature (4, 25 and 37 degrees C) and/or growth conditions. In glass tubes, formation of either a moderate or strong biofilm was observed in 15/57 (26.3%), 19/57 (33.3%) and 27/57 (47.4%), at 4, 25 and 37 degrees C, respectively. Desiccation treatment decreased Cronobacter viability by 1.55 to >3.87Log10CFU/mL. Cell-cell aggregation was observed in 17 (29.8%) strains. This study showed that the Cronobacter species evaluated showed differing phenotypes, independent of their origin (clinical or not) and ST. Further studies are necessary to elucidate the factors affecting phenotype expression. This may identify novel bacterial targets that could be useful in the development of strategies to control Cronobacter in food chain and to prevent cases of infections.

AB - Electrospinning is a method used in fiber production in which an electric force is applied to create jets of charged polymer solutions. The objective of this study was to obtain homogeneous nanofibers from lentil flour and hydroxypropyl methylcellulose (HPMC) blend by using electrospinning method. Distilled water was used as solvent. The effects of pH (7, 10 and 12), lentil flour concentration (1% and 2% (w/v)) and HPMC concentration (0.25%, 0.5% and 1% (w/v)) on solution properties and fiber morphology were investigated. When the pH was increased, the viscosity of the solutions containing 1% and 2% lentil flour decreased. Increasing the pH values caused an increase in the electrical conductivity. At pH value of 7, homogeneous nanofibers could not be obtained whereas fibers were perfectly homogeneous at alkaline pH values. Nanofiber diameter decreased with increase in pH when 2% lentil flour was used. On the other hand, diameter of fibers did not show any significant change with pH for 1% lentil flour. When the lentil flour concentration was increased, viscosity and fiber diameter increased at pH10. When HPMC concentration was increased, both viscosity and fiber diameter increased but electrical conductivity did not show any significant change. Average fiber diameters ranged between 198+/-4 and 254+/-5nm for solutions prepared with different lentil flour and HPMC concentrations at different pH values. PMID- 29195994 TI - Identification of variable genomic regions related to stress response in Oenococcus oeni. AB - The lactic acid bacterium Oenococcus oeni is the most important species involved in malolactic fermentation due to its capability to survive in presence of ethanol and in the acidic environment of wine. In order to identify novel genes involved in adaptation to wine, a new approach using genome-wide analysis based on stress-related genes was performed in strain O. oeni PSU-1, and 106 annotated stress genes were identified. The in silico analysis revealed the high similarity of all those genes through 57 O. oeni genomes; however, seven variable regions of genomic plasticity could be determined for their different presence observed among these strains. Regions 3 and 5 had the typical hallmarks of horizontal transfer, suggesting that the strategy of acquiring genes from other bacteria enhanced the fitness of O. oeni strains. Certain genes related to stress resistance were described in these regions, and similarities of putative acquired regions with other lactic acid bacteria species were found. Some genomic fragments present in all the strains were described and another new genomic island harbouring a threonine dehydrogenase was found. The association of selected sequences with adaptation to wine was assessed by screening 31 O. oeni strains using PCR of single genes, but no sequences were found to be exclusive to highly performing malolactic fermentation strains. This study provides new information about the genomic variability of O. oeni strains contributing to a further understanding of this species and the relationship of its genomic traits with the ability to adapt to stress conditions.

AB - The aim of this study was to evaluate technological and antioxidant properties, including in vitro bioaccessibility of polyphenols, conferred on raw anchovy mince by the addition of polyphenol-rich grape pomace dietary fibre at different concentrations. For this purpose, headed and gutted anchovy was heat-flayed, deboned and mixed with 0%, 2%, 3%, 4% grape pomace dietary fibre. A significant increase (P<0.05) in the concentration of polyphenols and associated antioxidant capacity was detected when grape pomace dietary fibre was incorporated in a proportion of at least 2% of the final mixture. In vitro digestion showed that the higher the grape pomace dietary fibre content, the higher was the proportion of polyphenols reaching the large intestine. Additionally, it was observed that the ABTS (2,2'-azino-bis(3-ethylbenzo-thiazoline-6-sulfonic acid) assay seems to be more suitable for evaluating antioxidant capacity in this kind of samples than FRAP (Ferric Reducing Antioxidant Power) assay. Technological properties such as mechanical and water holding, as well as sensory scores, indicated excellent qualities and acceptability of all samples. Hence, given the good acceptance of these samples, it should be feasible to make fish products based on mince anchovy as a means of increasing dietary intake of polyphenols with antioxidant capacity, especially considering the high concentration of polyphenols bioaccessible in the large intestine. PMID- 29195996 TI - Evaluation of Tempranillo and Albarino SO2-free wines produced by different chemical alternatives and winemaking procedures. AB - In this work physical and chemical alternatives to produce SO2 free wines are shown. The use of inactive yeast strains enriched in glutathione, chitosan, dimethyldicarbonate and different hydrolysable and condensed tannins were assessed in Tempranillo and Albarino wines. The time of addition, mixtures of additives and the use of inert gases were evaluated. In general, no significant differences on the sensory quality were shown when compared sulphited and non sulphited wines. Both physical and chemical treatments were more effective for Tempranillo wines. In the two studied vintages, non-sulphited Tempranillo wines were better valuated than controls, even when wines were produced only using the application of inert gases. No differences were observed when argon was used instead of carbon dioxide as inert gas. Mixtures of seed and skin tannins with inactive dry yeast enriched in glutathione were the most effective treatments. This work may help winemakers to elaborate healthier wines meeting the current consumer demands. PMID- 29195997 TI - Instrumental and sensory properties of pea protein-fortified extruded rice snacks. AB - Characteristic attributes of pea-protein fortified, extruded rice snacks were evaluated by mechanical, acoustic and descriptive sensory analysis. The addition of pea protein isolate (0 to 45% (w/w)) to rice flour and extruder screw speed strongly affected the expansion behaviour and therefore, textural attributes of extruded snack products. The sensory panel described the texture of highly expanded extrudates as crisp, while low expanded extrudates were perceived as hard, crunchy and non-crisp. Results of the instrumental and sensory analysis were compared and showed a high correlation between mechanical and sensory hardness (r=0.98), as well as acoustic and sensory crispness (r=0.88). However, poor and/or negative correlations between acoustic and sensory hardness and crunchiness were observed (r=-0.35 and -0.84, respectively). PMID- 29195998 TI - Transcriptome analysis reveals the effect of pre-harvest CPPU treatment on the volatile compounds emitted by kiwifruit stored at room temperature. AB - Kiwifruits are rich in nutrients beneficial to humans. Because forchlorfenuron (CPPU)-treatment after full bloom can enlarge fruit size, and significantly increase the income of farmers, it has been extensively used. However, CPPU might also influence fruit sugar and acid content, and storage performance. This study analyzed the differences in volatile emissions between CPPU-treated and water treated kiwifruits after two, four, six, or eight days of storage, and differential gene expression related to these compounds using high-throughput sequencing. The number of volatile compounds was relatively high at the first two days of storage for both treated and control fruits, decreased in the following days, and increased again, although less significantly in CPPU-treated than in control fruits. Aldehydes in the control and treated groups showed a trend of stability vs. down-regulation, alcohols or terpenes showed high-low-high vs. down regulation, and esters showed up-regulation vs. high-low-high, respectively. Only 60.12-66.68% of the genes obtained were mapped and 3370 new genes were annotated. Genes related to terpene biosynthesis were enriched, and, in CPPU-treated fruits, several genes related to hormone signal transduction were found in aldehydes, alcohols, and terpenes biosynthetic pathways. Although CPPU might influence the expression of genes encoding the core complex proteins in photosynthesis, its relationship with terpene synthesis is still unclear. Our results provided resources for the genetic annotation of kiwifruits, and revealed the impact of CPPU on the metabolism of their volatile compounds, laying the theoretical foundation for investigating the use of molecular techniques to inhibit the CPPU related reduction of fruit quality. PMID- 29195999 TI - The effect of raisins on biomarkers of endothelial function and oxidant damage; an open-label and randomized controlled intervention. AB - Based on the existing data in grapes and wine, the aim of the present study was to investigate the probability that raisins improve clinical features and markers of oxidative stress, inflammation and arterial function in healthy smokers. Thirty-six apparently healthy smokers were recruited to an open-label and randomized, controlled, 4-week prospective intervention. All participants were reported to consume less than the recommended amount of five servings fruits and vegetables daily. Participants in the intervention were instructed to consume raisins equal to five fruit servings (90g/d). Anthropometric and blood pressure (BP) measurements, assessment of dietary intake, and fasting blood draws were conducted at baseline and at week 4. Biochemical (glucose, lipids, liver enzymes), inflammation [C-reactive protein (CRP), leptin], oxidative stress [Malondialdehyde (MDA), Advanced oxidation protein products (AOPPs)] and arterial function markers [Flow-mediated dilatation (FMD), Pulse wave velocity (PWV), Intercellular adhesion molecule-1 (ICAM-1), Nitric oxide (NO)] were assessed pre- and post-intervention. Baseline characteristics did not differ between the intervention and control arm. No effect of daily raisin consumption was observed on markers assessed between baseline and week 4 in either arm. Regarding vegetable consumption, no difference was observed in either group between baseline and post-intervention; however, as expected, a significant increase was reported in the intervention arm in fruit consumption between baseline and end point (p<0.001) and between two arms post-intervention (p<0.001). When analyzing according to age, ICAM-1 levels significantly decreased in subjects >30years (n=8) in intervention arm (390.1+/-17.6 to 302.2+/-11ng/mL, p=0.004). After analysis of the data for sex, women in intervention (n=5) decreased significantly diastolic BP (74.6+/-4.2 to 67.4+/-2.6mg/dL, p=0.043), total cholesterol (175.8+/ 7 to 166.6+/-6.6mg/dL, p<0.001) and LDL-cholesterol (96.2+/-9.6 to 89+/ 10.5mg/dL, p=0.012). However, due to the small sample size in the above, no safe conclusions can be exported. PMID- 29196000 TI - Deep sequencing reveals high bacterial diversity and phylogenetic novelty in pit mud from Luzhou Laojiao cellars for Chinese strong-flavor Baijiu. AB - The pit mud (PM) in fermentation cellar is a complex ecosystem that hosts diverse microbial communities that contribute to the production of Chinese strong-flavor Baijiu (CSFB). However, the microbial ecology of PM, particularly the extent of their phylogenetic novelty remains poorly understood. Here we conducted Illumina MiSeq sequencing to explore the diversity and novelty patterns of PM bacterial communities from Luzhou Laojiao cellars in use for 40 and 400years. High diversity indices were found in the PM with 16 phyla and 105 genera. Interestingly, the compositions of dominant genera of the PM were significantly different than that reported previously for PM sampled from other geographic sites, suggesting greater microbial diversity of PM. The dominant genus of Caproiciproducens, a caproic acid-producing bacterium, is the first reported for Chinese Baijiu production. Our results demonstrate that the PM hosts a large number of novel taxa, with 26% of the total OTUs (operational taxonomic units) distant to cultured counterparts. The class Clostridia within Firmicutes presented the highest proportion of novel OTUs. Most novel OTUs were initially isolated from diverse environments, the most abundant of which came from Chinese Baijiu brewing ecosystems, highlighting the huge culturing gap within the PM, but at the same time suggesting the importance of these OTUs in CSFB production. The data presented in this study significantly increases the number of bacteria known to be associated with CSFB production and should help guide the future exploration of microbial resources for biotechnological applications. PMID- 29196001 TI - Allium tuberosum: Antidiabetic and hepatoprotective activities. AB - Allium tuberosum (AT) is traditionally used for treating nocturnal emissions, abdominal pain, diarrhea, sexual dysfunction and asthma. This study aimed at investigating the antidiabetic and hepatoprotective activities of the butyl alcohol fraction from the methanolic extract of A. tuberosum. For the antidiabetic activity, rats were induced with diabetes by intraperitoneal injection of 150mg/kg alloxan and treated for 30days with AT extract (100, 200 and 400mg/kg). Animals were sacrificed after the study and the fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), HDL, malondialdehyde (MDA) catalase, superoxide dismutase and glutathione levels were determined. The hepatoprotective assay, mice were pretreated for seven days with AT (100, 200 and 400mg/kg) and silymarin (100mg/kg or). Thereafter 10ml/kg of 2% v/v CCl4 was administered intraperitoneally on the 7th day to induce acute liver injury. Blood and liver samples were obtained and serum enzymes ALT, AST, ALP, SOD, GSH, CAT, MDA and pro-inflammatory mediators were assessed. AT significantly decrease FBG, serum TG, TC, MDA levels and significant increased HDL, SOD, GSH and CAT activities in the diabetic rats. In addition, AT significantly inhibited MDA, IL 1b, IL-6 and TNF-alpha levels and prevented the depletion of the antioxidant enzymes GSH, SOD and CAT activities in CCl4 induced liver damage. Furthermore, AT markedly reduced AST, ALT and ALP levels in the CCl4 treated mice groups. In conclusion, the antidiabetic and hepatoprotective effect of AT may be associated with its antioxidant and its ability to inhibit the pro-inflammatory mediators. PMID- 29196002 TI - In vitro and in vivo assessment of anti-hyperglycemic and antioxidant effects of Oak leaves (Quercus convallata and Quercus arizonica) infusions and fermented beverages. AB - The aim of this study was to evaluate the anti-hyperglycemic and antioxidant effects of oak leaves infusions and fermented beverages from Quercus convallata and Q. arizonica in vitro and in vivo. Female C57BL/6 mice fed with high saturated fat and fructose diet-induced obesity were treated with oak leaves beverages (200 MUL/per day equivalent to 15mg of lyophilized sample/Kg of body weight for infusions and 31mg of lyophilized sample/Kg of body weight for fermented beverages) for 3months and an oral glucose tolerance test (OGTT) was performed. Blood plasma was obtained for determination of glucose, lipid profile, and oxidative stress markers (ABTS, nitric oxide, and ORAC assays). Insulin resistance was estimated using the product of triglycerides and glucose (TyG). Oak leaves infusions and fermented beverages exhibited exerted inhibition of alpha-amylase (8-15% and 5-9%, respectively) and alpha-glucosidase (98% and 99%, respectively) enzymes. After OGTT, the groups treated with either oak leaves infusions or fermented beverages showed lower glucose levels compared with the obesity control group (18%) and a similar glucose tolerance to healthy control group. On long-term evaluation, intervention groups showed a significant reduction in fasting glucose concentrations (41-50% for oak leaves infusions and 52-66% for fermented beverages) and TyG index (4.2-4.6% for oak leaves infusions and 5.9-7.5% for fermented beverages) compared with the obese control group. Oak leaves infusions and fermented beverages had antioxidant potential in vitro and scavenging activity for radicals such as peroxyl and peroxynitrite anions. Our results suggest anti-hyperglycemic and antioxidant effects of beverages prepared with leaves of Quercus species in vitro and in vivo. PMID- 29196003 TI - Chemical profiling of guarana seeds (Paullinia cupana) from different geographical origins using UPLC-QTOF-MS combined with chemometrics. AB - Paullinia cupana, commonly known as guarana, is an Amazonian fruit whose seeds are used to produce the powdered guarana, which is rich in caffeine and consumed for its stimulating activity. The metabolic profile of guarana from the two largest producing regions was investigated using UPLC-MS combined with multivariate statistical analysis. The principal component analysis (PCA) showed significant differences between samples produced in the states of Bahia and Amazonas. The metabolites responsible for the differentiation were identified by orthogonal partial least squares discriminant analysis (OPLS-DA). Fourteen phenolic compounds were characterized in guarana powder samples, and catechin, epicatechin, B-type procyanidin dimer, A-type procyanidin trimer and A-type procyanidin dimer were the main compounds responsible for the geographical variation of the samples. PMID- 29196004 TI - Anti-inflammatory effect of dietary pork extract on proliferation and cytokine secretion using mouse primary splenocytes. AB - The anti-inflammatory effects of boiled pork meat (BPM) and hot water extracts of pork meat (WPM) on splenocyte proliferation and T cell cytokine regulation in BALB/c mice were evaluated. The proliferation of splenocytes in high concentration WPM groups was significantly higher than the control stimulated by LPS and Con A. In the white blood cells, WPM groups had significantly higher counts of lymphocytes and lower counts of neutrophils than the control (p<0.05). The Th1 (IFN-gamma, TNF-alpha, IL-2) and Th2 (IL-4, IL-5, IL-10) cytokine levels in high-concentration WPM groups were higher than those in the control. In addition, TNF-alpha/IL-10 and IL-2/IL-4 secretions of splenocytes in the high concentration WPM group with LPS or Con A treatment was significantly lower than the control (p<0.05). Therefore, this study suggested that high concentration of WPM had anti-inflammatory effects on the primary splenocyte, which indicating that water extracts of pork meat can enhance the immune system of mice. PMID- 29196005 TI - Inactivation of Escherichia coli O157:H7 and Bacillus cereus by power ultrasound during the curing processing in brining liquid and beef. AB - The objective of this study was to evaluate the effects of ultrasound on the number of Escherichia coli O157:H7 and vegetative cells of Bacillus cereus in brining and beef during the curing processing. The mechanisms of the inactivation for the pathogens were preliminarily explored. The ultrasound intensity (2.39, 6.23, 11.32 and 20.96Wcm-2) and sonication time (30, 60, 90 and 120min) at 10 degrees C were assessed in brine and meat. Plate count data indicated that 20.96Wcm-2 for 120min was the optimal treatment for bacterial reductions. E. coli O157:H7 was more susceptible to ultrasonic treatment in the first 30min than B. cereus in brine. However, a similar reduction percentage with around 40% in both cultures could be achieved when sonicated for 120min. Good fitness of Weibull model (R2>0.98; RMSE<0.12) was obtained with the distinct shape of the curves which predicted microbial inactivation by ultrasound in salt solution (6%). The production of hydrogen peroxide in brine by ultrasound confirmed the effects of ultrasound on the inactivation of microorganisms during the curing processing. The particle size distribution of bacterial and cell fluorescence staining analysis showed that ultrasound could result in the formation of cell fragments through destroying the integrality of the membrane of E. coli O157:H7 and B. cereus. However, the promoting effect of ultrasound on the number of bacteria in beef suggested that the sanitation conditions of equipment and raw meat must be paid attention when applying ultrasound for curing procedure. PMID- 29196006 TI - Understanding the influence of buckwheat bran on wheat dough baking performance: Mechanistic insights from molecular and material science approaches. AB - A molecular and material science approach is used to describe the influence of coarse and fine buckwheat bran on wheat dough properties and bread textural quality. Focus is given on (i) gluten solvation and structural arrangements in presence of bran as studied by front-face fluorescence; (ii) thermo-mechanical behavior of dough during heating studied by dynamic mechanical thermal analysis and (iii) texture of bread crumb analyzed in terms of a cellular solid. The thermo-mechanical behavior of dough was found to be largely related to starch phase transitions during heating. The use of thermodynamic approaches to biopolymer melting revealed that key transitions such as the onset of starch gelatinization were function of the interplay of water and bran volume fractions in the dough. Front-face fluorescence studies in wheat dough revealed that gluten solvation and structural arrangements were delayed by increasing bran addition level and reduction in particle size, as indicated by the drastic decrease in the protein surface hydrophobicity index. Variations in gluten structure could be strongly related to dough baking performance, i.e. specific volume. With regards to texture, the approach revealed that crumb texture was controlled by variations in density, moisture and bran volume fractions. Overall, this study elucidates a number of physical mechanisms describing the influence of buckwheat bran addition to dough and bread quality. These mechanisms strongly pointed at the influence of bran on water partitioning among the main polymeric components. In the future, these mechanisms should be investigated with bran material of varying source, composition and structure. PMID- 29196007 TI - Postharvest UV-C irradiation stimulates the non-enzymatic and enzymatic antioxidant system of 'Isabel' hybrid grapes (Vitis labrusca*Vitis vinifera L.). AB - Ultraviolet light type C (UV-C) was studied as a tool to increase enzymatic and non-enzymatic antioxidant defenses and phytochemical levels in 'Isabel' grapes (Vitis labrusca*Vitis vinifera L.). Grapes were exposed to 0, 0.5, 1.0, 2.0, or 4.0kJm-2 UV-C and stored for 1, 3, or 5days post-treatment. One day after UV-C irradiation, the activities of grape antioxidant enzymes and thiols were increased, especially at 1.0 and 2.0kJm-2. These doses increased total phenolic content by almost 20%, while 0.5 and 4.0kJm-2 had no effects. Total monomeric anthocyanin content was increased by >35% by UV-C at 1.0kJm-2; however, anthocyanin profile was unchanged. Grape skin antioxidant capacity was also improved by UV-C irradiation. The 1.0kJm-2 UV-C was considered the hormetic dose. Postharvest UV-C had an elicitor effect on 'Isabel' grapes, positively impacting the antioxidant capacity and phytochemical content. PMID- 29196008 TI - Influence of buttermilk powder or buttermilk addition on phospholipid content, chemical and bio-chemical composition and bacterial viability in Cheddar style cheese. AB - The effect of buttermilk powder addition post-curd formation or buttermilk addition to cheese milk on total and individual phospholipid content, chemical composition, enzyme activity, microbial populations and microstructure within Cheddar-style cheese was investigated. Buttermilk or buttermilk powder addition resulted in significant increases in total phospholipid content and their distribution throughout the cheese matrix. Addition of 10% buttermilk powder resulted in higher phospholipid content, moisture, pH and salt in moisture levels, and lower fat, fat in dry matter, L. helveticus and non-starter bacteria levels in cheeses. Buttermilk powder inclusion resulted in lower pH4.6/Soluble Nitrogen (SN) levels and significantly lower free amino acid levels in 10% buttermilk powder cheeses. Buttermilk addition provided a more porous cheese microstructure with greater fat globule coalescence and increased free fat pools, while also increasing moisture and decreasing protein, fat and pH levels. Addition of buttermilk in liquid or powdered form offers potential for new cheeses with associated health benefits. PMID- 29196009 TI - Stability of curcumin encapsulated in solid lipid microparticles incorporated in cold-set emulsion filled gels of soy protein isolate and xanthan gum. AB - The objective of this study was to investigate the feasibility of producing cold set emulsion filled gels (EFG), using soy protein isolate (SPI) and xanthan gum (XG) and incorporating curcumin-loaded solid lipid microparticles (SLM). For this purpose, the formulation GXG (15%, w/v SPI, 0.1%, w/v XG and 5mM CaCl2) was selected for the production of EFG. A comparative study on the rheological and microstructural properties of non-filled gels and EFG revealed that SLM stabilized with Tween 80-Span 80 behaved as active fillers in the gel matrix, increasing the Young's modulus from 1.1 to 2.3kPa, and also increasing the values of storage and loss moduli. The incorporation of SLM also affected the microstructural organization of the systems. Whereas unfilled gels presented a microstructural organization similar to that of interpenetrated networks, EFG exhibited a microstructure with clear phase separation. The stability of encapsulated curcumin in EFG was monitored using a colorimetric test and it was confirmed that the bioactive component showed a high stability for 15days. After that period, the color started to change, indicating a decrease in curcumin concentration. The instability of curcumin was probably related to structural alterations of the EFG, which led to decreases of hardness after 7days of storage at 10 degrees C, and to the collapse of the structures after 30days. Although formulation improvements are required, the results indicate that the encapsulation of curcumin in SLM incorporated in EFG is a potential alternative for the replacement of yellow artificial dyes in gelled food products. PMID- 29196010 TI - Evaluation of the heat damage of whey and whey proteins using multivariate analysis. AB - Maillard reaction (MR) was assessed in 10 powdered whey samples. Initial stages of MR were evaluated using furosine, intermediate stages with hydroxymethylfurfural (HMF) and absorbance at 284nm, advanced stages with color parameters (CIELab color) and final stages with browning index; additionally, insolubility, pH and water activity (Aw) were measured. Principal component analysis (PCA) and cluster analysis (CA) were used to establish the heat damage of samples based on relations between variables. Three principal components were found which explained 79.0% of the total variance and they were the basis for cluster analysis where 5 clusters were formed. PCA and CA can separate samples according to their heat damage and they help in a clearer interpretation of the information from indicators which shows that samples with high lactose content exhibited the higher heat damage.

AB - (-)-Epigallocatechin-3-O-gallate (EGCG), the major catechin present in green tea, exhibits potent antioxidant activity. We thereby investigated the presence of unknown components bearing the (-)-epigallocatechin (EGC) moiety in fresh tea leaf samples. Initially, liquid chromatography tandem mass spectrometry (LC MS/MS) was employed to examine fresh tea leaves of the Yabukita, the most popular tea cultivar in Japan, which suggested the presence of the EGC phenylpropanoid derivatives, (-)-epigallocatechin-3-O-p-coumaroate (EGCpCA) and (-) epigallocatechin-3-O-caffeoate (EGCCA). The structures of the detected EGCpCA and EGCCA were then confirmed by LC-MS/MS using synthesized EGCpCA and EGCCA as standards. In addition, EGCpCA and EGCCA were evaluated for their antioxidant activity in the ORAC (oxygen radical antioxidant capacity) and DPPH (2,2-diphenyl 1-picrylhydrazyl) radical scavenging assays, where EGCCA (8.60MUmolTE/MUmol, TE=Trolox equivalents) exhibited a stronger antioxidant activity than EGCG (5.52MUmolTE/MUmol) in the ORAC assay. Finally, EGCpCA and EGCCA were quantitated in several tea leaf samples using LC-MS/MS, and it was found that these compounds were present in lower quantities (EGCpCA, 16.8-345.8MUg/g, EGCCA, 4.3-75.1MUg/g in the dry tea leaves) than the major catechins. In this study, we found the potent antioxidant EGCCA using LC-MS/MS and revealed its wide existence in various tea leaves.

AB - The effects of repeated heat-moisture treatment (RHMT) and continuous heat moisture treatment (CHMT) on structural, physicochemical and digestibility properties of red adzuki bean starch have been investigated and compared. The results showed that the starch granules had many rupture and scallops and some of the polarization cross disappeared after CHMT and RHMT. The crystal type of CHMT and RHMT starches changed from C-type to A-type. The pasting temperatures and gelatinization transition temperatures of CHMT and RHMT starches increased, while the pasting viscosities (peak, trough, breakdown, final and setback viscosity), solubility and swelling power of CHMT and RHMT starches decreased compare to native starch. The RDS and SDS contents of starch samples were higher than native starch, which indicate that the digestibility was improved by CHMT and RHMT. On the whole, the RHMT measures have more advantages in the changes of starch structural, physicochemical and digestibility properties compared to CHMT ones. PMID- 29196013 TI - The potential of herbs and spices to reduce lipid oxidation during heating and gastrointestinal digestion of a beef product. AB - Here we tested the potential of ten culinary herbs (basil, oregano, rosemary and thyme) and spices (black pepper, cayenne pepper, cumin, curcuma, garlic and sweet paprika) to limit oxidation during cooking of a high-fat beef product, and during its subsequent in vitro gastrointestinal digestion. The herbs and spices were added separately at 0.5% and 1% (w/w), either during meat processing before heating of the product or after heating of the meat as a seasoning. Lipid oxidation was evaluated by malondialdehyde, 4-hydroxy-2-nonenal and hexanal quantification in the meat products and gastrointestinal digests. In general, adding the herbs and spices before heating of the meat was more effective at limiting oxidation during digestion, compared to adding these compounds after heating. Doses of 1% were more effective than 0.5%. The four herbs and curcuma displayed antioxidant activity in all treatments and were more effective in limiting oxidation than the other culinary compounds, resulting in negligible concentrations of 4-hydroxy-2-nonenal and hexanal in the meat and digests. Black pepper, cayenne pepper and cumin moderately reduced or had no effect on oxidation during digestion when added following heating of the meat, but had a more pronounced antioxidant effect when added before heating. Sweet paprika and garlic exerted some pro-oxidant effects during cooking. During digestion, sweet paprika had an antioxidant effect, but garlic did not. The extent to which the herbs and spices limited oxidation, showed a strong correlation with their phenolic content, and lower correlations with alpha-tocopherol and chlorophyll.

AB - Shewanella putrefaciens biofilm formation is of great concern for the shrimp industry because it adheres easily to food and food-contact surfaces and is a source of persistent and unseen contamination that causes shrimp spoilage and economic losses to the shrimp industry. Different concentrations of an antimicrobial lipopeptide, the fermentation product of Bacillus subtilis, AMPNT 6, were tested for the ability to reduce adhesion and disrupt S. putrefaciens preformed biofilms on two different contact surfaces (shrimp shell, stainless steel sheet). AMPNT-6 displayed a marked dose- and time-dependent anti-adhesive effect>biofilm removal. 3MIC AMPNT-6 was able both to remove biofilm and prevent bacteria from forming biofilm in a 96-well polystyrene microplate used as the model surface. 2MIC AMPNT-6 prevented bacteria from adhering to the microplate surface to form biofilm for 3h and removed already existing biofilm within 24h. Secretion of extracellular polymeric substances incubated in LB broth for 24h by S. putrefaciens was minimal at 3* MIC AMPNT-6. Scanning electron microscopy showed that damage to S. putrefaciens bacteria by AMPNT-6 possibly contributed to the non-adherence to the surfaces. Disruption of the mature biofilm structure by AMPNT-6 contributed to biofilm removal. It is concluded that AMPNT-6 can be used effectively to prevent attachment and also detach S. putrefaciens biofilms from shrimp shells, stainless steel sheets and polystyrene surfaces.

AB - The agroindustrial residues have been recognized as important sources of some prominent chemical compounds and hence a viable strategy of obtaining bioactive compounds could be applied to them. The present study was aimed to investigate the presence of bioactive compounds and the antioxidant activity of some Brazilian exotic fruits (achachairu, araca-boi, bacaba) residues. The antioxidant capacity of fruit residues was evaluated by ORAC, FRAP and ABTS assays. The contents of total phenolic compounds, flavonoids, chlorophylls and carotenoids were determined. The identification and quantification of the phenolic compounds were performed by using the UHPLC-QqQ-MS/MS system. The compounds cinnamic acid, p-coumaric acid, epicatechin and quercetin were identified and quantified in all fruits residues. The residue with the highest antioxidant capacity was bacaba for ORAC (15,285.51+/-20.38MUmolTE/100g) and FRAP (16,916.37+/-10.01MUmolTE/100g) assays, as well as total phenolic compounds in its methanolic extract (1537.45+/ 73.35mgGAE/100g).

Trotter], an ancient cereal mainly produced in Ethiopia, is increasingly getting higher acceptance in the global market because it is gluten free and has high iron content. The aim of this study was to evaluate the in vitro dialysability of Fe and Zn in a backslop fermented gluten free flat bread known as injera. The traditional fermentation caused up to 49-66% reduction of phytic acid (PA). Molar ratios of PA:Fe and PA:Zn decreased from 14 to 1 and from 63 to 19, respectively, after 120h of fermentation. The total soluble fractions of Fe and Zn ranged between 11 and 38% and between 11 and 29%, respectively, after 120h of fermentation. The dialyzable Fe content of the white varieties ranged between 3 and 9% after 120h fermentation while no effect was observed for the brown varieties. The dialyzable Zn ranged between 2 and 11%, with only a clear effect of fermentation in one white variety. Consumption of tef could be a good source of Fe and Zn, but may not provide the absolute recommended daily Fe and Zn intakes.

AB - Taking over vehicle control from a Level 3 conditionally automated vehicle can be a demanding task for a driver. The take-over determines the controllability of automated vehicle functions and thereby also traffic safety. This paper presents models predicting the main take-over performance variables take-over time, minimum time-to-collision, brake application and crash probability. These variables are considered in relation to the situational and driver-related factors time-budget, traffic density, non-driving-related task, repetition, the current lane and driver's age. Regression models were developed using 753 take over situations recorded in a series of driving simulator experiments. The models were validated with data from five other driving simulator experiments of mostly unrelated authors with another 729 take-over situations. The models accurately captured take-over time, time-to-collision and crash probability, and moderately predicted the brake application. Especially the time-budget, traffic density and the repetition strongly influenced the take-over performance, while the non driving-related tasks, the lane and drivers' age explained a minor portion of the variance in the take-over performances. PMID- 29196018 TI - Differentiating the influence of incidental anger and fear on risk decision making. AB - Previous research has revealed that incidental emotions of different valence (positive/negative/neutral) produce distinct impacts on risk decision-making. This study went on to compare the effects of different emotions of which the valence are identical. We focused on anger and fear, both of which are negative emotions but differ in motivational and appraisal dimensions. Participants finished a forced-choice gambling task, during which incidental emotions (anger/fear/happy) were elicited by facial stimuli selected from the Chinese Facial Affective Picture System. Behavioral and event-related potential (ERP) data were recorded in the experiment, which showed that anger and fear were different in their influence on behavioral risk preference and the relationship between outcome processing and subsequent risk decisions. Regarding the behavioral results, risk preference in the anger condition was higher than the fear condition, but lower than the happy condition. Regarding the ERP results elicited by outcome feedback (gain/loss), in the fear condition, the feedback related negativity (FRN) was positively correlated with risk preference; in the anger condition, the gain-related P3 component was positively correlated with risk preference; in the happy condition, both the FRN and the loss-related P3 was negatively correlated with risk preference. The current findings provide novel insight into distinguishing the effect of different incidental emotions on risk preference. PMID- 29196020 TI - Evaluation of Multifocality and Multicentricity With Breast Magnetic Resonance Imaging in Each Breast Cancer Subtype. AB - INTRODUCTION: The purpose of this study was to evaluate whether diagnostic performance of breast magnetic resonance imaging (MRI) for detection of multifocality and multicentricity (MFMC) of breast cancer (BC) can be influenced by different histotypes or immunophenotypes in newly diagnosed patients with breast cancer. MATERIALS AND METHODS: In this institutional review board-approved retrospective study, 289 patients who underwent both preoperative breast MRI and radical or modified mastectomy in our institution because of primary BCs were selected. Patients were stratified based on the pathologic report in 2 main histotypes and 5 immunophenotypes. By matching the radiologic report with the corresponding pathologic report for each patient, breast MRI performance for detection of MFMC were obtained in each histotype and immunophenotype and subsequently compared. RESULTS: Overall breast MRI sensitivity for MFMC detection was 88.1%, specificity was 80.0%, positive predictive value 82.1%, negative predictive value 85.8%, diagnostic accuracy 83.7%, and area under the curve 0.835. Breast MRI sensitivity for MFMC detection in triple-negative BC was 84.6% (P = .88), specificity 70.8% (P = .63), positive predictive value 61.1% (P = .02), negative predictive value 89.5% (P = .20), diagnostic accuracy 75.7% (P = .65), and area under the curve 0.777 (P = .87). CONCLUSION: Performance of breast MRI for the detection of MFMC are not influenced by the BC histotypes, in accordance with published literature. Conversely, the triple-negative immunophenotypes demonstrated lower performance, statistically significant only for positive predictive value (P = .02), for the detection of MFMC. PMID- 29196021 TI - Advanced imaging to predict response to chemotherapy in colorectal liver metastases - a systematic review. AB - BACKGROUND: The assessment of colorectal liver metastases (CRLM) after treatment with chemotherapy is challenging due to morphological and/or functional change without changes in size. The aim of this review was to assess the value of FDG PET, FDG-PET-CT, CT and MRI in predicting response to chemotherapy in CRLM. METHODS: A systematic review was undertaken based on PRISMA statement. PubMed and Embase were searched up to October 2016 for studies on the accuracy of PET, PET CT, CT and MRI in predicting RECIST or metabolic response to chemotherapy and/or survival in patients with CRLM. Articles evaluating the assessment of response after chemotherapy were excluded. RESULTS: Sixteen studies met the inclusion criteria and were included for further analysis. Study results were available for 6 studies for FDG-PET(-CT), 6 studies for CT and 9 studies for MRI. Generally, features predicting RECIST or metabolic response often predicted shorter survival. The ADC (apparent diffusion coefficient, on MRI) seems to be the most promising predictor of response and survival. In CT-related studies, few attenuation-related parameters and texture features show promising results. In FDG-PET(-CT), findings were ambiguous. CONCLUSION: Radiological data on the prediction of response to chemotherapy for CRLM is relatively sparse and heterogeneous. Despite that, a promising parameter might be ADC. Second, there seems to be a seemingly counterintuitive correlation between parameters that predict a good response and also predict poor survival. PMID- 29196022 TI - A Systematic review and meta-analysis on the role of palliative primary resection for pancreatic neuroendocrine neoplasm with liver metastases. AB - BACKGROUND: Role of palliative pancreatic neuroendocrine neoplasm (PanNEN) resection (pPanNEN-R) is controversial. This study was designed as a meta analysis of studies which allow a comparison of pPanNEN-R and non-surgical management (PanNEN-nR). METHODS: All published studies until 2017 allowing for the comparison of pPanNEN-R and PanNEN-nR were reviewed. Primary outcome was overall survival (OS). Secondary outcomes measures included postoperative morbidity, reoperation, readmission, length of hospital stay (LOS), and quality of life (QoL). Risk of death was compared by computing the odds-ratio (OR), while 5- and 10-year OS using weighted mean differences. RESULTS: Seven studies were included. A total of 885 patients were included, of whom 252 (28%) underwent pPanNEN-R and 633 (72%) underwent PanNEN-nR. Overall quality of included studies was fair. The risk of death was significantly reduced in patients who underwent pPanNEN-R compared to those who underwent PanNEN-nR (OR = 0.38, 95% CI 0.23 0.65). Data on postoperative morbidity, reoperation, readmission, LOS, and QoL were not adequately reported therefore a meta-analysis for the secondary outcomes was not performed. DISCUSSION: pPanNEN-R in patients with unresectable LM seems to be associated with a better OS compared to non-surgical management but the limitations of included studies does not allow firm conclusions. PMID- 29196023 TI - Zataria multiflora would attenuate the hepatotoxicity of long-term albendazole treatment in mice with cystic echinococcosis. AB - Hepatic injury is the major limitation of long-term albendazole administration in patients with cystic echinococcosis (CE), which could give rise to cessation of treatment. The objective of the present study was to evaluate the protective effects of Zataria multiflora aromatic water (AW) against the hepatic injury induced by long-term albendazole treatment in mice with CE. Fifty healthy BALB/c female mice were infected intraperitoneally by injection of 1500 protoscoleces per animal. Five months after infection, the infected animals were divided into five treatment groups including Z. multiflora (40ml/l in drinking water for 90days), albendazole (200mg/kg/day for 90days), Z. multiflora+albendazole 200 (40ml/l Z. multiflora and 200mg/kg/day albendazole for 90days), Z. multiflora+albendazole100 (40ml/l Z. multiflora and 100mg/kg/day albendazole for 90days), and untreated (control) group. At the end of the treatment period, anesthesia was performed and blood samples were collected directly from the heart prior to euthanasia. Liver variables and oxidative stress markers were measured in the blood serum samples. A decrease in serum liver enzyme activity in the both Z. multiflora+albendazole groups was observed when compared to control, Z. multiflora and albendazole groups; however, the results for Z. multiflora+albendazole 100 were significant (p<0.007) and superior compared to those for Z. multiflora+albendazole 200. No significant differences for oxidative stress markers were observed between the different groups. The results of the present study revealed that a combined therapy with Z. multiflora AW and albendazole is effective against hepatic injury induced by CE and/or long term albendazole administration in mice with cystic echinococcosis. PMID- 29196024 TI - Poly(methyl vinyl ether-co-maleic acid) for enhancement of solubility, oral bioavailability and anti-osteoporotic effects of raloxifene hydrochloride. AB - Raloxifene HCl (RH) has poor water solubility and due to its extensive first pass metabolism; its bioavailability is only 2%. The purpose of the present study was to enhance the aqueous solubility, oral bioavailability and anti-osteoporotic effects of RH by electro-sprayed nanoparticles (NPs) in ovariectomized rats. NPs containing RH and different ratio of poly(methyl vinyl ether-co-maleic acid) (PMVEMA) were electrosprayed. The voltage, distance of needle to the collector, flow rate of the solution and polymeric percentage were optimized according to the size of NPs and drug solubility. The optimized formulation was characterized by SEM, XRD, DSC, and FTIR. The pharmacokinetic parameters were studies by oral administration of a single dose of 15mg/kg in Wistar rats. The anti-osteoporotic effects were studied in female ovariectomized rats. Animals were treated with 6mg/kg/day for 2months then serum calcium, phosphorous and alkaline phosphatase levels were measured. RH loaded electrosprayed NPs showed 10-fold enhanced solubility compared to the free drug. Moreover, the XRD and SEM tests displayed an amorphous state of drug in the NPs. FTIR and DSC tests revealed no interaction between the polymer and the drug. Serum calcium, phosphorous and alkaline phosphatase levels were significantly decreased in ovariectomized rats receiving oral RH NPs (P<0.05). No significant difference was detected between RH NPs and estradiol groups (P>0.05). Oral bioavailability of NPs showed 7.5-fold increase compared to the pure drug. The electrosprayed PMVEMA nanoparticles can enhance solubility, bioavailability and antiosteoporotic effects of RH.

PMID- 29196026 TI - Long-term Changes in the Nigrostriatal Pathway in the MPTP Mouse Model of Parkinson's Disease. AB - Parkinson's disease (PD) is a common and progressive neurodegenerative disorder. The 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of PD is widely used to study the progression of this disease. Behavior impairment is closely related to the damage of the dopaminergic system in the basal ganglia. Here, MPTP-induced changes in mouse behavior and glial activation were evaluated at different time points after the treatment and the long-term changes in the nigrostriatal pathway were analyzed. We found that mice exposed to MPTP displayed a full recovery in the rotarod test and the pole test but not in the wire hanging test at 65 days post-injection. A biphasic activation of microglial cells was revealed in the nigrostriatal pathway of MPTP-treated mice. However, activation of astrocytes displayed an approximately bell-shaped kinetics and an approximately S-shaped kinetics in the striatum and the substantia nigra, respectively. In addition, the numbers of complement component 3 (C3)-positive neurotoxic astrocytes in the substantia nigra of MPTP-treated mice increased with time and reached a maximum at 42 days, and declined at 74 days, after the treatment. Three months later, the dopaminergic system was partially recovered from the lesion of MPTP. The time course of pathophysiological events has important implications for the interventions or treatment of PD. PMID- 29196027 TI - Cancer Chemotherapy in Early Life Significantly Alters the Maturation of Pain Processing. AB - Advances in pediatric cancer treatment have led to a ten year survival rate greater than 75%. Platinum-based chemotherapies (e.g. cisplatin) induce peripheral sensory neuropathy in adult and pediatric cancer patients. The period from birth through to adulthood represents a period of maturation within nociceptive systems. Here we investigated how cisplatin impacts upon postnatal maturation of nociceptive systems. Neonatal Wistar rats (Postnatal day (P) 7) were injected (i.p.) daily with either vehicle (PBS) or cisplatin (1mg/kg) for five consecutive days. Neither group developed mechanical or thermal hypersensitivity immediately during or after treatment. At P22 the cisplatin group developed mechanical (P < 0.05) and thermal (P < 0.0001) hypersensitivity versus vehicle group. Total DRG or dorsal horn neuronal number did not differ at P45, however there was an increase in intraepidermal nerve fiber density in cisplatin-treated animals at this age. The percentage of IB4+ve, CGRP+ve and NF200+ve DRG neurons was not different between groups at P45. There was an increase in TrkA+ve DRG neurons in the cisplatin group at P45, in addition to increased TrkA, NF200 and vGLUT2 immunoreactivity in the lumbar dorsal horn versus controls. These data highlight the impact pediatric cancer chemotherapy has upon the maturation of pain pathways and later life pain experience. PMID- 29196028 TI - Serum Response Factor Promotes Dopaminergic Neuron Survival via Activation of Beclin 1-Dependent Autophagy. AB - Serum response factor (SRF), a transcription factor highly expressed in neurons, is involved in neuronal survival and the pathogenesis of some neurodegenerative disorders. The ablation of SRF renders the midbrain dopaminergic (DA) neurons vulnerable to 1-methyl 4-phenyl 1,2,3,6-tetrahydropyridine-induced neurotoxicity, however, the underlying mechanisms remain poorly understood. Here, we report decreased SRF levels in the substantia nigra (SN) of rotenone-treated rats that was associated with the loss of tyrosine hydroxylase (TH)-positive neurons. SRF expression was also reduced in rotenone-treated PC12 cells in vitro. In addition, Srf knockdown augmented rotenone-induced toxicity in PC12 cells. In contrast, overexpression of Srf attenuated the cells' sensitivity to rotenone and alleviated rotenone-induced alpha-synuclein accumulation. The protective effect of SRF was abolished when the expression of autophagy-related proteins Beclin 1 and Atg5 was suppressed. These results suggested that SRF may promote DA neuron survival by regulating autophagy, and thus serves as a critical molecule in PD progression. PMID- 29196029 TI - Assessment of phototoxicity in pigmented Long-Evans rat: sparfloxacin and 8 methoxypsoralen. AB - The aim of the present work was to evaluate the effects of photo-activated toxicity induced after administration of two known melanin-binding phototoxic compounds, sparfloxacin (SPX) and 8-methoxypsoralen (8-MOP), followed or not by UVA/Vis exposure, in pigmented rats (Long Evans: LE) and albino rats (Sprague Dawley: SD). Groups of three rats were treated with SPX or 8-MOP by oral gavage for six consecutive days. Irradiated animals were submitted to a UVA/Vis light dose standardized to 10 J/cm2 UVA daily. Clinical signs, cutaneous reactions and body weight were monitored throughout the study period. Ear biopsy weight, lymph node weight and lymph node cell count were determined at necropsy. Ophthalmologic examinations were performed before the first treatment and on the day of sacrifice. Microscopic examinations were performed on skin biopsies and eyes. Phototoxicity was demonstrated for both SPX and 8-MOP in the pigmented and albino strains, in terms of auricular irritation, lymph node weight and proliferation index, cutaneous reactions and ocular histopathology. LE rats were less sensitive than SD rats, especially at the ocular level, supporting the notion that pigmentation may provide protection against photo-activation. The pigmented rat may be a more relevant model than the albino rat for human safety evaluation. PMID- 29196030 TI - Expert opinions on the acceptance of alternative methods in food safety evaluations: Formulating recommendations to increase acceptance of non-animal methods for kinetics. AB - Inclusion of alternative methods that replace, reduce, or refine (3R) animal testing within regulatory safety evaluations of chemicals generally faces many hurdles. The goal of the current work is to i) collect responses from key stakeholders involved in food safety evaluations on what they consider the most relevant factors that influence the acceptance and use of 3R methods and to ii) use these responses to formulate activities needed to increase the acceptance and use of 3R methods, particularly for kinetics. The stakeholders were contacted by e-mail for their opinions, asking the respondents to write down three barriers and/or drivers and scoring these by distributing 5 points over the three factors. The main barriers that obtained the highest aggregated scores were i) uncertain predictability 3R methods/lack of validation, ii) insufficient guidance regulators/industry and iii) insufficient harmonization of legislation. The major driver identified was the possibility of 3R methods to provide more mechanistic information. Based on the results, recommendations are given to enhance the acceptance and application of 3R toxicokinetic methods in food safety evaluations. These include steering of regulatory data requirements as well as creating (funding) opportunities for development and validation of alternative methods for kinetics and development of guidances. PMID- 29196031 TI - Effects of various feeding patterns of Bacillus coagulans on growth performance, antioxidant response and Nrf2-Keap1 signaling pathway in juvenile gibel carp (Carassius auratus gibelio). AB - The present study was conducted to evaluate the effects of various Bacillus coagulans feeding patterns on growth, antioxidant parameter and Nrf2 pathway in juvenile gibel carp. The similar size of gibel carp (initial weight: 14.33 +/- 0.15 g) were subjected to three levels of B. coagulans supplementation (0, 500, and 1000 mg/kg) and two feeding modes (supplementing B. coagulans continuously or for two days of B. coagulans after 5 days of a basal diet) according to a 3 * 2 factorial design. The fish that were continuously fed 500 mg/kg B. coagulans (P2) and those fed the first basal diet for 5 days followed by 500 mg/kg or 1000 mg/kg B.coagulans for 2 days (P4 or P5) showed higher weight gain rate and specific growth rate than the other groups. Blood respiratory burst (RB), myeloperoxidase (MPO), and anti-superoxide anion free radical (AFASER) activities in the P4 group were higher than those of the control. White blood cell count (WBC), RB activity, MPO activity, and glutathione (GSH) content in the P5 group were also higher than those of the control. A similar higher trend was observed in the gene expressions of NADPH oxidase 2 (NOX2), NFE2-related factor (Nrf2), Kelch-like-ECH-associated protein(Keap1) in the P4 and NOX2, NRF2, CNC homolog 1 (Bach1), peroxiredoxin 2 (Prx2) in the P5 group compared with the control. Additionally, we observed a significantly lower level of plasma aspartate aminotransferase (AST), lower activity of alanine aminotransferase (ALT), a higher level of MPO, higher GPX activity, and increased NRF2 and Prx2 expression were all observed in the P2 treatment group compared with the control. Furthermore, the malondialdehyde (MDA) content in the P2, P3, and P4 groups was lower than that of the control. These results indicate that a diet supplemented with appropriate levels of B.coagulans could improve the growth, immune response, and antioxidant capability of gibel carp. We concluded that the pattern of two days of 500 or 1000 mg/kg B. coagulans after 5 days of a basal diet was recommended for gibel carp.

AB - The human brain is remarkably plastic. The brain changes dramatically across development, with ongoing functional development continuing well into the third decade of life and substantial changes occurring again in older age. Dynamic changes in brain function are thought to underlie the innumerable changes in cognition, emotion, and behavior that occur across development. The brain also changes in response to experience, which raises important questions about how the environment influences the developing brain. Longitudinal functional magnetic resonance imaging (fMRI) studies are an essential means of understanding these developmental changes and their cognitive, emotional, and behavioral correlates. This paper provides an overview of common statistical models of longitudinal change applicable to developmental cognitive neuroscience, and a review of the functionality provided by major software packages for longitudinal fMRI analysis. We demonstrate that there are important developmental questions that cannot be answered using available software. We propose alternative approaches for addressing problems that are commonly faced in modeling developmental change with fMRI data. PMID- 29196034 TI - Adie pupil. Pilocarpine test.

AB - Recent evidences suggest that insulin delivery to the brain can be an important pharmacological therapy for some neurodegenerative pathologies, including Alzheimer disease (AD). Due to the presence of the Blood Brain Barrier, a suitable carrier and an appropriate route of administration are required to increase the efficacy and safety of the treatment. Here, poly(N-vinyl pyrrolidone)-based nanogels (NG), synthetized by e-beam irradiation, alone and with covalently attached insulin (NG-In) were characterized for biocompatibility and brain delivery features in a mouse model. Preliminarily, the biodistribution of the "empty" nanocarrier after intraperitoneal (i.p.) injection was investigated by using a fluorescent-labeled NG. By fluorescence spectroscopy, SEM and dynamic light scattering analyses we established that urine clearance occurs in 24h. Histological liver and kidneys inspections indicated that no morphological alterations of tissues occurred and no immunological response was activated after NG injection. Furthermore, after administration of the insulin conjugated nanogels (NG-In) through the intranasal route (i.n.) no alteration or immunogenic response of the nasal mucosa was observed, suggesting that the formulation is well tolerated in mouse. Moreover, an enhancement of NG-In delivery to the different brain areas and of its biological activity, measured as Akt activation levels, with reference to free insulin administration was demonstrated. Taken together, these results indicate that the synthesized NG-In enhances brain insulin delivery upon i.n. administration and strongly encourage its further evaluation as therapeutic agent against some neurodegenerative diseases. PMID- 29196042 TI - Multilayer polyion complex nanoformulations of superoxide dismutase 1 for acute spinal cord injury. AB - As one of the most devastating forms of trauma, spinal cord injury (SCI) remains a challenging clinical problem. The secondary processes associated with the primary injury, such as overproduction of reactive oxygen species (ROS) and inflammation, lead to concomitant compression of the injured spinal cord and neuronal death. Delivery of copper-zinc superoxide dismutase (SOD1), an efficient ROS scavenger, to the site of injury can mitigate SCI-induced oxidative stress and tissue damage. Towards this goal catalytically active nanoformulations of SOD1 ("nanozymes") are developed as a modality for treatment of SCI. Along with the cross-linked polyion complex of SOD1 with polycation poly(ethylene glycol) (PEG)-polylysine (single-coat (SC) nanozyme), we introduce for the first time the chemically cross-linked multilayer polyion complex in which SOD1 is first incorporated into a polyion complex with polycation, then coated by anionic block copolymer, PEG-polyglutamic acid (double-coat (DC) nanozyme). We developed DC nanozymes with high enzymatic activity and ability to retain and protect SOD1 under physiological conditions. Pharmacokinetic study revealed that DC nanozymes significantly prolonged circulation of active SOD1 in the blood stream compared to free SOD1 or SC nanozymes (half-life was 60 vs 6min). Single intravenous injection of DC nanozymes (5kU of SOD1/kg) improved the recovery of locomotor functions in rats with moderate SCI, along with reduction of swelling, concomitant compression of the spinal cord and formation of post-traumatic cysts. Thus, based on the testing in a rodent model the SOD1 DC nanozymes are promising modality for scavenging ROS, decreasing inflammation and edema, and improving recovery after SCI.

AB - Little is known about the in vivo fate of drug particles taken orally, in particular, the drug release kinetics and interaction with the gastrointestinal (GI) membrane. Lacking is analytical means that can reliably identify the integrity of drug particles under the complexity of biological environment. Herein, we explored fluorescent probes whose signals become quenched upon being released from drug carriers. Taking advantage of so-called the aggregation caused quenching (ACQ), particles may be identified by the integrated fluorophores, which are "turned off" when the particles become destructed and dyes are released. In the current study, ultrafine amorphous particles (UAPs) of cyclosporin A (CsA) were prepared with synthesized ACQ dyes physically entrapped. The fluorescence intensity of suspension of these UAPs was found correlated well with the dissolution of the particles. When given to rats orally, it was found that some of the administered UAPs could survive the animal's GI tracts for as long as 18h. Whole-body fluorescence imaging detected fluorescent signals in the liver and lungs. Particularly noticed in sections of jejunum and ileum, the detection suggested the possibility of direct absorption of UAPs through epithelial membranes. Moreover, 250nm particles were absorbed faster via transepithelia than larger ones (550nm), while the latter were preferably taken up by M cells in the follicle-associated epithelium (FAE) region of Peyer's patches. In vitro permeation studies with Caco-2 cells confirmed the transmembrane transport of the dye-integrated UAPs. Our study supports the idea of using ACQ fluorophores for imaging and characterizing the fate of intact particles in a biological environment.

AB - The establishment of more effective treatments that can circumvent chemoresistance in Multiple Myeloma (MM) is a priority. Although bortezomib (BTZ) is one of the most potent proteasome inhibitors available, still possesses limitations related to dose limiting side effects. Several strategies have been developed to improve the delivery of chemotherapies to MM by targeting different moieties expressed on MM cells to nanoparticle delivery systems (NPs), which have failed mainly due to their heterogeneous expression on these cells. Our goal was to test CD38 targeted chitosan NPs as novel targeting moiety for MM to improve the potency and efficacy of BTZ in MM cells and reduce the side effects in healthy tissue. We have showed preferential BTZ release in tumor microenvironment, specific binding to MM cells, and an improved drug cellular uptake through BTZ diffusion from the surface and endocytosed NPs, which translated in enhanced proteasome inhibition and robust cytotoxic effect on MM cells when BTZ was administered through anti-CD38 chitosan NPs. Furthermore, the anti-CD38 chitosan NPs specifically delivered therapeutic agents to MM cells improving therapeutic efficacy and reducing side effects in vivo. The anti-CD38 chitosan NPs showed low toxicity profile allowing enhancement of proteasome inhibitory activity and specificity of BTZ by endocytosis-mediated uptake of CD38 representing a promising therapy in MM. PMID- 29196047 TI - Antibiotic administration in the ambulance? PMID- 29196049 TI - Chronic glucocorticoid treatment induced circadian clock disorder leads to lipid metabolism and gut microbiota alterations in rats. AB - AIM: Glucocorticoids (GCs), steroid hormones synthetized by the adrenal gland, are regulated by circadian cycles, and dysregulation of GC signaling can lead to the development of metabolic syndrome. The effects and potential mechanism of GCs in physiology were investigated in the present study. MAIN METHODS: Male Wistar rats were orally administered dexamethasone sodium phosphate (DEX, 0.01 and 0.05mg/kg body weight per day) for 7weeks. KEY FINDING: DEX treatment attenuated body weight gain and reduced food intake, whereas it induced the accumulation of fat. Administration of DEX induced dysregulation of the expression of lipogenic genes in both fat and liver. Moreover, the mRNA levels of genes related to mitochondrial biogenesis and function were significantly downregulated in the liver and fat of DEX-treated rats. Furthermore, DEX treatment caused a significant reduction in the richness and diversity of the microbiota in the colon, as assessed using high-throughput sequencing of the 16s rRNA gene V3-V4 region, an increase in inflammatory cell infiltration, and a decrease in mucus secretion in the colon. Additionally, DEX administration induced phase shift or loss of circadian rhythmicity of clock-related genes in peripheral tissues. These results were associated with higher serum corticosterone levels and upregulation of GC receptor (GR) expression in peripheral tissues. SIGNIFICANCE: Our findings indicate that long-term administration of GC caused lipid accumulation, changes in the structure of the intestinal flora, and reduced colonic mucus secretion in vivo. The mechanism of these physiological changes may involve a circadian rhythm disorder and dysregulation of GR expression. PMID- 29196046 TI - Prehospital antibiotics in the ambulance for sepsis: a multicentre, open label, randomised trial. AB - BACKGROUND: Emergency medical services (EMS) personnel have already made substantial contributions to improving care for patients with time-dependent illnesses, such as trauma and myocardial infarction. Patients with sepsis could also benefit from timely prehospital care. METHODS: After training EMS personnel in recognising sepsis, we did a randomised controlled open-label trial in ten large regional ambulance services serving 34 secondary and tertiary care hospitals in the Netherlands. We compared the effects of early administration of antibiotics in the ambulance with usual care. Eligible patients were randomly assigned (1:1) using block-randomisation with blocks of size 4 to the intervention (open-label intravenous ceftriaxone 2000 mg in addition to usual care) or usual care (fluid resuscitation and supplementary oxygen). Randomisation was stratified per region. The primary outcome was all-cause mortality at 28 days and analysis was by intention to treat. To assess the effect of training, we determined the average time to antibiotics (TTA) in the emergency department and recognition of sepsis by EMS personnel before and after training. The trial is registered at ClinicalTrials.gov, number NCT01988428. FINDINGS: 2698 patients were enrolled between June 30, 2014, and June 26, 2016. 2672 patients were included in the intention-to-treat analysis: 1535 in the intervention group and 1137 in the usual care group. The intervention group received antibiotics a median of 26 min (IQR 19-34) before arriving at the emergency department. In the usual care group, median TTA after arriving at the emergency department was 70 min (IQR 36-128), compared with 93 min (IQR 39-140) before EMS personnel training (p=0.142). At day 28, 120 (8%) patients had died in the intervention group and 93 (8%) had died in the usual care group (relative risk 0.95, 95% CI 0.74-1.24). 102 (7%) patients in the intervention group and 119 (10%) in the usual care group were re-admitted to hospital within 28 days (p=0.0004). Seven mild allergic reactions occurred, none of which could be attributed to ceftriaxone. INTERPRETATION: In patients with varying severity of sepsis, EMS personnel training improved early recognition and care in the whole acute care chain. However, giving antibiotics in the ambulance did not lead to improved survival, regardless of illness severity. FUNDING: The NutsOhra Foundation, Netherlands Society of Internal Medicine (NIV). PMID- 29196048 TI - Developmental competence and apoptotic gene expression patterns of mature and immature human oocytes retrieved from controlled ovarian stimulation cycles. AB - The purpose was to assess the developmental competence of the in vitro or in vivo matured human oocytes as well as the apoptotic genes expression of cumulus cells (CCs) regarding nuclear maturity status of associated oocytes retrieved from stimulated ICSI cycles. A total of 590 oocytes and the associated CCs were retrieved and divided into groups of test and control according to the nuclear maturity status in order to the developmental evaluation as well as expression patterns of apoptosis-related genes using real time PCR. The fertilization and embryo formation rates were 60.3% and 87.5% vs.69.1% and 92.8% in test and control groups, respectively. Good quality embryos on day 3 were 62.2% in test and 69.1% in control groups. There were significant differences in the rates of normal fertilized as well as unfertilized oocytes between the groups. Also, mRNA levels of some apoptotic genes were significantly higher in the CCs obtained from immature oocytes among patients with premature ovarian factors (POF) rather than other infertility etiologies (p < 0.001). The data demonstrated the developmental competence of in vitro matured oocytes -even to good quality cleavage embryos- is not completely consistent with molecular integrity and well-mannered gene expression patterns resulting to ICSI success. It seems that using immature oocytes could be helpful for patients at risk of ovarian hyperstimulation syndrome (OHSS) as the same as patients with diminished ovarian reserve. PMID- 29196050 TI - Alpha-tocopherol succinate increases cyclooxygenase-2 activity: Tissue-specific action in pregnant rat uterus in vitro. AB - AIMS: Lipid soluble vitamin E plays a role in several physiological mechanisms, however, the mechanism of this action is controversial. We investigated how tocopherol (alpha-tocopherol acid succinate) influences the effects of cyclooxygenase inhibitors (COXi) in the smooth muscles. MAIN METHODS: The contractility of the samples from 22-day-pregnant myometrium and non-pregnant myometrium and trachea was determined in an isolated organ bath in vitro. The activity of cyclooxygenase enzymes (COX) was also measured in the tissues. KEY FINDINGS: Diclofenac (10-9-10-5M) and rofecoxib (10-10-10-5M) decreased the contractions in non-pregnant and 22-day-pregnant uteri. Tocopherol (10-7M) increased the relaxant effect only in pregnant uteri. Both diclofenac (10-9-10 5M) and rofecoxib (10-10-10-5M) reduced the tracheal tones, while they were slightly intensified by pretreatment with tocopherol (10-7M). Tocopherol enhanced the contractions of pregnant uteri. Tocopherol (10-7M) itself can induce the cyclooxygenase activity and shift the COX-1 and COX-2 ratio to COX-2. The lowest COX activity was found in non-pregnant uteri, while the highest one was in the trachea. SIGNIFICANCE: The COX enzymes, especially COX-2, play an important role in the contraction of pregnant uteri in rat. Tocopherol has a tissue specific COX 2 activity increasing effect in pregnant rat uterus but has no such action in non pregnant uteri or tracheal tissue. Hereby, tocopherol may intensify selectively the uterine relaxing effect of COX-2 inhibitors in preterm contractions. However, tocopherol can enhance the contractile response of pregnant uterus that may increase the risk of premature contractions. PMID- 29196051 TI - Lycium barbarum polysaccharides improve CCl4-induced liver fibrosis, inflammatory response and TLRs/NF-kB signaling pathway expression in wistar rats. AB - Lycium barbarum polysaccharides (LBPs) have multiple biological and pharmacological functions, including antioxidant, anti-inflammatory and anticancer activities. This research was conducted to evaluate whether LBPs could alleviate carbon tetrachloride (CCl4)-induced liver fibrosis and the underlying signaling pathway mechanism. Fifty male wistar rats were randomly allocated to five groups (n=10): control, CCl4 and CCl4 with 400, 800 or 1600mg/kg LBPs, respectively. Each wistar rat from each group was used for blood and tissue collections at the end of experiment. The results showed that CCl4 induced liver fibrosis as demonstrated by increasing histopathological damage, alpha-smooth muscle actin expression, aspartate transaminase activities, alkaline phosphatase activities and alanine aminotransferase activities. LBPs supplementation alleviated CCl4-induced liver fibrosis as demonstrated by reversing the above parameters. In addition, CCl4 treatment induced the oxidative injury, increased the mRNA levels of tumor necrosis factor-alpha, monocyte chemoattractant protein 1 and interleukin-1beta, and up-regulated the protein expressions of toll-like receptor 4 (TLR4), TLR2, myeloid differentiation factor 88, nuclear factor-kappa B (NF-kB) and p-p65. LBPs supplementation alleviated CCl4-induced oxidative injury, inflammatory response and TLRs/NF-kB signaling pathway expression by reversing the above some parameters. These results suggest that the alleviating effects of LBPs on CCl4-induced liver fibrosis in wistar rats may be through inhibiting the TLRs/NF-kB signaling pathway expression. PMID- 29196052 TI - Ferulic acid-loaded nanostructured lipid carriers: A promising nanoformulation against the ischemic neural injuries. AB - AIMS: Treatment of the ischemic stroke has remained a major healthcare challenge. The phenolic compound, ferulic acid (FA), has shown promising antioxidant and neuroprotective effects, however, low bioavailability may negatively affect its efficiency. This, prompted us to incorporate FA into the nanostructured lipid carriers (FA-NLCs) and evaluate its therapeutic potential in in vitro and in vivo models of ischemic stroke. MAIN METHODS: FA-NLCs were prepared by high-pressure homogenization followed by physicochemical characterization, evaluation of the bioactivity of FA-NLCs in oxygen-glucose deprivation (OGD) and global cerebral ischemia/reperfusion (I/R) injury and implication of phosphatidylinositol 3 kinase (PI3K) pathway in this regard. KEY FINDINGS: Formation of FA-NLCs which exhibited a controlled release profile, was confirmed by scanning electron microscope and differential scanning calorimetry. 1- and 8-h OGD followed by 24h re-oxygenation significantly reduced PC12 cell viability, increased lactate dehydrogenase activity and number of condensed nuclei, and induced oxidative stress as revealed by increased malondialdehyde and decreased glutathione content and superoxide dismutase and catalase activities. FA (80 and 100MUM) reduced the cytotoxicity, oxidative stress, and cellular damage only after 1-h OGD, while, FA NLCs (containing 80 and 100MUM of FA) were effective at both time points. Intravenous injections of FA-NLCs (20 and 25mg/kg) into rats significantly attenuated I/R-induced neurobehavioural deficits, cellular damage, and oxidative stress, while, FA failed. Pre-treatment with PI3K inhibitor, LY294002, abolished the protective effects against OGD or I/R. SIGNIFICANCE: FA-NLCs by improving the pharmacological profile of FA and activating PI3K pathway might be of therapeutic value in cerebral stroke. PMID- 29196053 TI - Centchroman regulates breast cancer angiogenesis via inhibition of HIF 1alpha/VEGFR2 signalling axis. AB - AIMS: Angiogenesis is a recognized hallmark of cancer which promotes cancer cell progression and metastasis. Inhibition of angiogenesis to attenuate cancer growth is becoming desirable strategy for breast cancer management. The present study is aimed to investigate the antiangiogenic efficacy of a novel selective estrogen receptor modulator Centchroman (CC) on human breast cancer cells. MAIN METHODS: Effect of CC on cell viability was evaluated using Sulforhodamine B assay. Endothelial cell proliferation, wound healing, Boyden chamber cell invasion, tube formation and chorioallantoic membrane (CAM) assays were performed to assess the effect of CC on migration, invasion and angiogenesis. Apoptosis, reactive oxygen species generation, caspase-3/7 and intracellular calcium ion level were measured through flow cytometry. Expression levels of HIF-1alpha, VEGF, VEGFR2, AKT and ERK were assessed by western blot analysis. KEY FINDINGS: CC selectively induces apoptosis in human breast cancer cells without affecting non-tumorigenic breast epithelial cells MCF-10A. Moreover, it inhibits migratory, invasive and mammosphere forming potential of breast cancer. Furthermore, CC also inhibited VEGF-induced migration, invasion and tube formation of HUVECs in vitro. CC effectively inhibited neovasculature formation in chicken CAM. Western blot analysis demonstrated that CC inhibited expression of HIF-1alpha and its downstream target VEGF. Interestingly, CC also suppressed VEGFR2 phosphorylation and consequently attenuated AKT and ERK phosphorylation. SIGNIFICANCE: Our findings suggest that CC downregulates VEGF-induced angiogenesis by modulating HIF-1alpha/VEGFR2 pathway and recommend it (CC) as a potential therapeutic drug for breast cancer treatment. PMID- 29196054 TI - Circular economy of plastic packaging: Current practice and perspectives in Austria. AB - Plastics, especially from packaging, have gained increasing attention in waste management, driving many policy initiatives to improve the circularity of these materials in the economy to increase resource efficiency. In this context, the EU has proposed increasing targets to encourage the recycling of (plastic) packaging. To accurately calculate the recycling rates, detailed information on the flows of plastic packaging is needed. Therefore, the aim of this paper is to quantitatively and qualitatively investigate the waste management system for plastic packaging in Austria in 2013 using material flow analysis, taking into account the used product types and the polymer composition. The results show that 300,000 +/- 3% t/a (35 kg/cap.a) of waste plastic packaging were produced, mainly composed of large and small films and small hollow bodies, including PET bottles. Correspondingly, the polymer composition of the waste stream was dominated by LDPE (46% +/- 6%), PET (19% +/- 4%) and PP (14% +/- 6%). 58% +/- 3% was collected separately, and regarding the final treatment, 26% +/- 7% of the total waste stream was recovered as re-granulates, whereas the rest was thermally recovered in waste-to-energy plants (40% +/- 3%) and the cement industry (33% +/- 6%). The targets set by the EU and Austria were reached comfortably, although to reach the proposed future target major technological steps regarding collection and sorting will be needed. However, the current calculation point of the targets, i.e. on the input side of the recycling plant, is not deemed to be fully in line with the overall objective of the circular economy, namely to keep materials in the economy and prevent losses. It is therefore recommended that the targets be calculated with respect to the actual output of the recycling process, provided that the quality of the output products is maintained, to accurately assess the performance of the waste management system.

AB - The objective of this study was to evaluate the kinetic parameters of pyrolysis of waste wood from reforestation: Eucalyptus benthamii (EB), Eucalyptus dunnii (ED) and Pinus elliottii (PN). The kinetic study was performed using the Friedman, Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS), Starink, and Vyazovkin methods from the experimental data at four heating rates (5, 10, 20 and 30 degrees C min-1). The Friedman method presented higher activation energy values (Ea) when compared to the other methods (EaEB = 142.98 kJ mol-1, EaED = 147.71 kJ mol-1, EaPN = 155.46 kJ mol-1). The KAS, Starink and Vyazovkin methods resulted in approximate values of activation energy (EaEB = 132.83-133.31 kJ mol 1, EaED = 137.51-137.98 kJ mol-1, EaPN = 145.24-145.70 kJ mol-1) due to the approximation equations with lowest relative errors. The simulation of curves using the kinetic parameters obtained with the Vyazovkin method showed that the decomposition process of EB and ED occurs as a multi-step process resulting in an unsatisfactory result for the simulation. On the other hand, for PN a satisfactory fit to the experimental data was obtained, which demonstrates its suitability for application to the modeling of thermochemical systems. PMID- 29196056 TI - Modeling the fate and end-of-life phase of engineered nanomaterials in the Japanese construction sector. AB - To date construction materials that contain engineered nanomaterials (ENMs) are available at the markets, but at the same time very little is known about their environmental fate. Therefore, this study aimed at modeling the potential fate of ENMs by using the example of the Japanese construction sector and by conducting a dynamic material flow analysis. Expert interviews and national reports revealed that about 3920-4660 tons of ENMs are annually used for construction materials in Japan. Nanoscale TiO2, SiO2, Al2O3 and carbon black have already been applied for decades to wall paints, road markings or concrete. The dynamic material flow model indicates that in 2016 about 95% of ENMs, which have been used since their year of market penetration, remained in buildings, whereas only 5% ended up in the Japanese waste management system or were diffusely released into the environment. Considering the current Japanese waste management system, ENMs were predicted to end up in recycled materials (40-47%) or in landfills (36-41%). It was estimated that only a small proportion was used in agriculture (5-7%, as ENM containing sewage sludges) or was diffusely released into soils, surface waters or the atmosphere (5-19%). The results indicate that ENM release predominantly depend on their specific applications and characteristics. The model also highlights the importance of adequate collection and treatment of ENM-containing wastes. In future, similar dynamic flow models for other countries should consider, inasmuch as available, historical data on ENM production (e.g. like declaration reports that are annually published by relevant public authorities or associations), as such input data is very important regarding data reliability in order to decrease uncertainties and to continuously improve model accuracy. In addition, more environmental monitoring studies that aim at the quantification of ENM release and inadvertent transfer, particularly triggered by waste treatment processes, would be needed in order to validate such models.

AB - In this review we focus on demonstrating how organic electronic materials can solve key problems in biosensing thanks to their unique material properties and implementation in innovative device configurations. We highlight specific examples where these materials solve multiple issues related to complex sensing environments, and we benchmark these examples by comparing them to state-of-the art commercially available sensing using alternative technologies. We have categorized our examples by sample type, focusing on sensing from body fluids in vitro and on wearable sensors, which have attracted significant interest owing to their integration with everyday life activities. We finish by describing a future trend for in vivo, implantable sensors, which aims to build on current progress from sensing in biological fluids ex vivo. PMID- 29196058 TI - Comparison of dystonia between Parkinson's disease and atypical parkinsonism: The clinical usefulness of dystonia distribution and characteristics in the differential diagnosis of parkinsonism. AB - OBJECTIVE: Dystonia is occasionally found in patients with Parkinson's disease (PD) and atypical parkinsonisms. However, systematic comparative analysis of the association between dystonia and parkinsonism have seldom been reported. The goals of this study are to compare the clinical characteristics and distributions of dystonia between PD, multiple system atrophy (MSA), progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD). METHODS: We prospectively enrolled 176 patients who presented with dystonia and parkinsonism out of 1278 patients with parkinsonism. We analyzed the clinical features of dystonia and parkinsonism. RESULTS: The frequencies of dystonia were 11.0% in PD, 20.9% in MSA, 40.7% in PSP and 66.7% in CBD. Dystonia symptoms were most frequent in CBD and relatively more frequent in PSP and MSA (p<0.001). Moreover, multiple types of dystonia occurred most frequently in MSA (p=0.034). According to the distribution of dystonia, cranio-facial dystonia (CFD) and cervical dystonia (CD) were more frequently observed in atypical parkinsonism (p=0.001). In contrast, limb dystonia (LD) was more frequently observed in both PD and CBD, and truncal dystonia (TD) was more frequently detected in PD (p<0.001). Levodopa medication related dystonia was markedly more frequent in PD than in atypical parkinsonism (p=0.030). CONCLUSIONS: In this long-term, observational, prospective study, we concluded that levodopa medication related LD and TD were more frequently observed in PD than in atypical parkinsonism. Conversely, levodopa medication non related CFD and CD were more frequently observed in atypical parkinsonism, and coexisting of some types of multiple dystonia may be unique features of atypical parkinsonism. TD or multiple types of LD, might be representative of PD rather than atypical parkinsonism. PMID- 29196059 TI - Importance rating of risk factors of ischemic stroke in patients over 85 years old in the polish population. AB - INTRODUCTION: The European population is aging and the number of elderly patients suffering from ischemic brain stroke increases. A better knowledge of the correlation between the risk factors and the course of the disease in old people may be useful for planning medical care and prophylactic strategies. AIM: This prospective study aimed to perform a demographic and clinical analysis of the etiology of ischemic stroke, survival rate and severity of post-stroke disability in patients who developed ischemic stroke at the age of over 85 years in the Polish population. METHOD: The study group consisted of 159 patients over 85 years old with ischemic stroke. The prevalence of risk factors such as sex, hypertension, hyperlipidemia, atrial fibrillation, heart failure and diabetes was evaluated. The outcome was assessed using the Barthel scale and the National Institutes of Health Stroke Scale. RESULTS: The most common risk factors of ischemic stroke were hypertension and atrial fibrillation. Patients with atrial fibrillation had a more severe course of ischemic stroke. CONCLUSION: The course of brain stroke in the Polish population is more severe in patients over 85 years old than in younger ones. The key risk factor in this group is atrial fibrillation. PMID- 29196060 TI - miR-365 promotes diabetic retinopathy through inhibiting Timp3 and increasing oxidative stress. AB - miRs play critical roles in oxidative stress-related retinopathy pathogenesis. miR-365 was identified in a previously constructed library from glyoxal-treated rat Muller cell. This report explores epigenetic alterations in Muller cells under oxidative stress to develop a novel therapeutic strategy. To examine the miR-365 expression pattern, in situ hybridization and quantitative RT-PCR were performed. Bioinformatical analysis and dual luciferase report assay were applied to identify and confirm target genes. Streptozotocin (STZ)-treated rats were used as the diabetic retinopathy (DR) model. Lentivirus-mediated anti-miR-365 was delivered subretinally and intravitreally into the rats' eyes. The functional and structural changes were evaluated by electroretinogram (ERG), histologically, and through examination of expression levels of metallopeptidase inhibitor 3 (Timp3), glial fibrillary acidic protein (Gfap), recoverin (Rcvrn) and vascular endothelia growth factor A (Vegfa). Oxidative stress factors and pro-inflammatory cytokines were analyzed. miR-365 expression was confirmed in the glyoxal-treated rat Muller cell line (glyoxal-treated rMC-1). In the retina, miR-365 mainly localized in the inner nuclear layer (INL). The increased miR-365 participated in Muller cell gliosis through oxidative stress aggravation, as observed in glyoxal-treated rMC 1 and DR rats before 6 weeks. Timp3 was a target and negatively regulated by miR 365. When miR-365 was inhibited, Timp3 expression was upregulated, Muller cell gliosis was alleviated, and retinal oxidative stress was attenuated. Visual function was also partially rescued as detected by ERG. miR-365 was found to be highly expressed in the retina and the abnormality of miR-365/Timp3 pathway is closely related to the pathology, like Muller gliosis, and the visual injury in DR. The mechanism might be through oxidative stress, and miR-365/Timp3 could be a potential therapeutic target for treating DR. PMID- 29196061 TI - Direct regulation of p190RhoGEF by activated Rho and Rac GTPases. AB - Rho family GTPases regulate a wide range of cellular processes. This includes cellular dynamics where three subfamilies, Rho, Rac, and Cdc42, are known to regulate cell shape and migration though coordinate action. Activation of Rho proteins largely depends on Rho Guanine nucleotide Exchange Factors (RhoGEFs) through a catalytic Dbl homology (DH) domain linked to a pleckstrin homology (PH) domain that subserves various functions. The PH domains from Lbc RhoGEFs, which specifically activate RhoA, have been shown to bind to activated RhoA. Here, p190RhoGEF is shown to also bind Rac1.GTP. Crystal structures reveal that activated Rac1 and RhoA use their effector-binding surfaces to associate with the same hydrophobic surface on the PH domain. Both activated RhoA and Rac1 can stimulate exchange of nucleotide on RhoA by localization of p190RhoGEF to its substrate, RhoA.GDP, in vitro. The binding of activated RhoA provides a mechanism for positive feedback regulation as previously proposed for the family of Lbc RhoGEFs. In contrast, the novel interaction between activated Rac1 and p190RhoGEF reveals a potential mechanism for cross-talk regulation where Rac can directly effect stimulation of RhoA. The greater capacity of Rac1 to stimulate p190RhoGEF among the Lbc RhoGEFs suggests functional specialization. PMID- 29196063 TI - Childhood maltreatment and non-suicidal self-injury: clinical implications. PMID- 29196062 TI - Childhood maltreatment and non-suicidal self-injury: a systematic review and meta analysis. AB - BACKGROUND: Non-suicidal self-injury is being increasingly recognised as a prominent public health concern. Identification of early and modifiable risk factors is necessary to advance the screening and intervention efforts, particularly early detection of at-risk individuals. We aimed to examine childhood maltreatment, including its specific subtypes, in relation to non suicidal self-injury. METHODS: We did a comprehensive meta-analysis of childhood maltreatment (overall, sexual abuse, physical abuse and neglect, and emotional abuse and neglect) in association with non-suicidal self-injury. We also provided a qualitative review of mediators and moderators of this association. We identified relevant articles published from inception to Sept 25, 2017, through a systematic search of Embase, MEDLINE, and PsycINFO. We extracted continuous and categorical data and assessed for potential moderators using ten study characteristics. We generated random-effects models for analysis and evaluated for publication bias. FINDINGS: We identified 71 publications that met eligibility criteria. Overall childhood maltreatment was associated with non suicidal self-injury (odds ratio 3.42, 95% CI 2.74-4.26), and effect sizes for maltreatment subtypes ranged from 1.84 (1.45-2.34) for childhood emotional neglect to 3.03 (2.56-3.54) for childhood emotional abuse. Publication bias was not evident, except in the case of childhood emotional neglect. Across multiple maltreatment subtypes, we found stronger associations with non-suicidal self injury in non-clinical samples. INTERPRETATION: With the exception of childhood emotional neglect, childhood maltreatment and its subtypes are associated with non-suicidal self-injury. Screening of childhood maltreatment history in non suicidal self-injury risk assessments might hold particular value in community settings, and increased attention to childhood emotional abuse is warranted.

AB - BACKGROUND: Tension pneumocephalus is a rare but life-threatening condition in which air gains entry into the cranium and exerts mass effect on the brain, resulting in increased intracranial pressure. It occurs most frequently secondary to head trauma, particularly to the orbits or sinuses. CASE REPORT: A 13-year-old male sustained facial trauma from a motor vehicle collision and was found to have tension pneumocephalus on computer tomography. The patient underwent immediate rapid sequence intubation without preceding positive pressure ventilation in the emergency department. At the time of his craniotomy, the tension pneumocephalus was found to have resolved and he went on to have a complete recovery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Any patient with facial or head trauma and pneumocephalus is at risk for the potential development of tension pneumocephalus. When present, we advocate that aggressive definitive airway management by rapid sequence intubation without preceding positive pressure ventilation and early surgical management should be prioritized.

AB - In the present study we comprehensively characterize intratesticular sex steroid production, metabolism and receptors in the domestic cat to elucidate the role of testosterone, estradiol and progesterone in testis development, steroid synthesis and spermatogenesis. There is a great demand for new concepts of fertility control in domestic (feral) cats and wild felids. The acquired knowledge will help to understand the regulation of spermatogenesis in felids, and may reveal new target points for male contraception. Progesterone and androgens are produced throughout all stages of testicular development; their synthesizing enzymes are mainly expressed in Leydig cells, and to a much lesser extent also in tubular cells. Aromatase (CYP19A1), the estrogen synthesizing enzyme, is only present in the tubuli and is first detectable in spermatocytes and round spermatids at puberty. As shown by elevated expression of the enzymes steroid 5-alpha-reductase type 1 (SRD5A) and aldo-keto-reductase family 1 member C3 (AKR1C3), the capacity to metabolize particular steroids increases during testis development. Apparently, this refers to a decreasing intra-testicular testosterone concentration per mg tissue with increasing testis weight during postpuberty. The increasing potential of sulfation of E2 by estrogen sulfotransferase (SULT1E1) with ongoing development might be responsible for the low level of unconjugated intratesticular estradiol in all stages of development probably due to facilitated excretion of conjugated estrogens. For the first time, expression of the progesterone membrane receptor components 1 and 2 (PGRMC1, PGRMC2) was studied in mammalian testis tissue. Both of these and also the progesterone receptor (PGR) are expressed depending on the developmental stage and cell type, suggesting an important regulatory role of progesterone in the testis. Androgen receptor (AR) is present in almost all cell types except for some spermatogenic cells. The co-localization of aromatase with estrogen receptor alpha (ESR1) in spermatocytes and round spermatids of domestic cat testis indicates an auto /paracrine function of estrogen in spermatogenesis. In summary, the testis of the domestic cat is an important source of sex steroids. All of them could act within the testis but additionally, at least androgens and estrogens are likely secreted by the testis, partly as conjugated steroids. PMID- 29196067 TI - Margin Assessment in Renal Surgery Using a Handheld Optical Coherence Tomography Probe. AB - OBJECTIVE: To assess the use of a handheld optical coherence tomography (OCT) probe for the evaluation of intraoperative surgical margins during partial nephrectomy (PN). METHODS: In an initial feasibility study, a radical nephrectomy specimen with a 9-cm tumor was cut into 19 sections, exposing 0 mm (n = 8), 1 mm (n = 6), and 2 mm (n = 5) gross margins. OCT was used to determine the margin width in each specimen. Second, a prospective ex vivo assessment of 15 PN tumor specimens was performed with OCT to determine margin status and to measure the attenuation coefficient of tumor and renal parenchyma. RESULTS: Median OCT margin width measurements for sectioned samples were 0 mm, 0.9 mm (range 0.7-2.9 mm), and 2.7 (range 1.65-2.8 mm) for grossly 0 mm (positive), 1 mm, and 2 mm margins, respectively. The difference between measurements from all margin groups was statistically significant (P <.04). The sensitivity and specificity for identifying positive margins were both 100%. In the PN specimens, OCT correctly found that all specimens had negative margins (within <.0001). CONCLUSION: We have demonstrated the feasibility of using a handheld OCT probe to assess margins ex vivo during PN. OCT may reduce the need for intraoperative frozen section and aid in minimizing parenchymal excision. PMID- 29196066 TI - Cough Due to TB and Other Chronic Infections: CHEST Guideline and Expert Panel Report. AB - BACKGROUND: Cough is common in pulmonary TB and other chronic respiratory infections. Identifying features that predict whether pulmonary TB is the cause would help target appropriate individuals for rapid and cost-effective screening, potentially limiting disease progression and preventing transmission to others. METHODS: A systematic literature search for individual studies to answer eight key questions (KQs) was conducted according to established Chest Organization methods by using the following databases: MEDLINE via PubMed, Embase, Scopus, and the Cochrane Database of Systematic Reviews from January 1, 1984, to April 2014. Searches for KQ 1 and KQ 3 were updated in February 2016. An updated KQ 2 search was undertaken in March 2017. RESULTS: Even where TB prevalence is greatest, most individuals with cough do not have pulmonary TB. There was no evidence that 1, 3, or 4 weeks' duration were better predictors than cough lasting >= 2 weeks to screen for pulmonary TB. In people living with HIV (PLWHIV), screening for fever, night sweats, hemoptysis, and/or weight loss in addition to cough (any World Health Organization [WHO]-endorsed symptom) increases the diagnostic sensitivity for TB. Although the diagnostic accuracy of symptom-based screening remains low, the negative predictive value of the WHO-endorsed symptom screen in PLWHIV may help to risk-stratify individuals who are not close TB contacts and who do not require further testing for pulmonary TB in resource-limited settings. However, pregnant PLWHIV are more likely to be asymptomatic, and the WHO-endorsed symptom screen is not sensitive enough to be reliable. Combined with passive case finding (PCF), active case finding (ACF) identifies pulmonary TB cases earlier and possibly when less advanced. Whether outcomes are improved or transmission is reduced is unclear. Screening asymptomatic patients is cost-effective only in populations with a very high TB prevalence. The Xpert MTB/RIF assay on sputum is more cost-effective than clinical diagnosis. To our knowledge, no published comparative studies addressed whether the rate of cough resolution is a reliable determinant of the response to treatment or whether the rate of cough resolution was faster in the absence of cavitary lung disease. All studies on cough prevalence in Mycobacterium avium complex (MAC) lung disease, other nontuberculous mycobacterial infections, fungal lung disease, and paragonimiasis were of poor quality and were excluded from the evidence review. CONCLUSIONS: On the basis of relatively few studies of fair to good quality, we conclude that most individuals at high risk and household contacts with cough >= 2 weeks do not have pulmonary TB, but we suggest screening them regardless of cough duration. In PLWHIV, the addition of the other WHO-endorsed symptoms increases the diagnostic sensitivity of cough. Earlier screening of patients with cough will help diagnose pulmonary TB sooner but will increase the cost of screening. The addition of ACF to PCF will increase the number of pulmonary TB cases identified. Screening asymptomatic individuals is cost-effective only in groups with a very high TB prevalence. Data are insufficient to determine whether cough resolution is delayed in individuals with cavitary lung disease or in those for whom treatment fails because of drug resistance, poor adherence, and/or drug malabsorption compared with results in other individuals with pulmonary TB. Cough is common in patients with lung infections due to MAC, other nontuberculous mycobacteria, fungal diseases, and paragonimiasis.

AB - Bladder malignancy in patients with congenital bladder anomalies who have undergone bladder augmentation is a rare but well-recognized condition. These patients present with locally advanced or metastatic disease and have poor survival. We report a case of a patient with myelomeningocele who was incidentally found to have a high-grade intestinal type adenocarcinoma of her bladder augment at the time of cystolithotomy. This case highlights the need to continue to follow patients with congenital bladder anomalies and highlights the lack of adequate screening methods available. PMID- 29196069 TI - Impact of Allergy and Resistance on Antibiotic Selection for Recurrent Urinary Tract Infections in Older Women. AB - OBJECTIVES: To review the impact of antibiotic allergy and resistance in older women with recurrent urinary tract infections (RUTIs) as determinants for a suitable oral antibiotic treatment choice. METHODS: A prospectively maintained database of women 65 years old and older with documented RUTIs (>=3 UTI/y) and trigonitis on cystoscopy was reviewed. Demographic data, known drug allergies, renal function, antibiotic susceptibility of most recent urine culture, allergy, or resistance to trimethoprim-sulfamethoxazole (TMP-SMX), fluoroquinolones, and nitrofurantoin were obtained. RESULTS: From 2006 to 2014, 86 women with RUTIs met study criteria. Mean age was 77.9 +/- 7.8, with 94% being Caucasian. An estimated glomerular filtration rate >30 mL/min was noted in 94%. The percentage of women allergic, resistant, or both allergic and resistant to TMP-SMX was 33%, 29%, and 15%, to fluoroquinolones was 14%, 34%, and 8.1%, or nitrofurantoin was 16%, 14%, and 5%, respectively. Twenty-eight percent (24 of 86) of women who were allergic and/or resistant to TMP-SMX and fluoroquinolones were sensitive to nitrofurantoin. Twenty percent (17 of 86) were allergic and/or resistant to all 3 antibiotics. Women who were allergic or resistant to TMP-SMX had a significantly higher number of other antibiotic resistances compared with women sensitive to TMP-SMX (4.9 +/- 3.6 vs 2.1 +/- 2.3; P < .0001). Similarly, women with fluoroquinolone allergy or resistance had significantly more antibiotic resistances than those who were fluoroquinolone sensitive (5.8 +/- 3.5 vs 2.3 +/- 2.5; P < .0001). CONCLUSION: Because of allergy and/or antibiotic resistance, several first-line antibiotics are not available for many older women with RUTIs. In nearly a third of women, nitrofurantoin was the only viable alternative. PMID- 29196070 TI - Evaluation of Urinary DNA Methylation as a Marker for Recurrent Bladder Cancer: A 2-Center Prospective Study. AB - OBJECTIVE: To clarify the clinical utility of urinary DNA methylation for detection of intravesical recurrence of non-muscle invasive BCa (NMIBC), we performed a 2-center prospective study. PATIENTS AND METHODS: A series of 207 self-voided urine samples were prospectively collected from 132 patients with NMIBC who had undergone transurethral resection of BCa. Methylation of miRNA genes (miR-9-3, miR-124-2, miR-124-3, and miR-137) was analyzed using bisulfite pyrosequencing. The primary end point was detection of intravesical recurrence; the secondary end point was prediction of late recurrence. The number of methylated genes (M-score) or quantitative level of methylation were compared with outcomes. RESULTS: Twenty-six urine specimens were collected on the same day intravesical recurrence was detected, and 14 were collected from patients whose recurrences were found during the subsequent follow-up period (0-632 days, mean, 342.2 days). For detection of current recurrence, M-scores achieved 61.5% sensitivity and 74.0% specificity, and the area under the ROC curve was 0.71. Regarding prediction of late recurrence, patients with a high M-score (>=3) showed worse recurrence-free survival (P <.01). Multivariate analysis revealed that high M-scores were independently associated with current (P = .028) and late recurrence (P = .026). Elevated levels of urinary DNA methylation were also strongly associated with recurrence and radical cystectomy. CONCLUSION: Our data suggest that urinary methylation of miRNA genes may be a useful marker for detecting and predicting BCa recurrence. PMID- 29196071 TI - Percutaneous Tibial Nerve Stimulation in the Office Setting: Real-world Experience of Over 100 Patients. AB - OBJECTIVE: To examine the outcomes and compliance with percutaneous tibial nerve stimulation (PTNS) for overactive bladder (OAB) symptoms. METHODS: Adults who had PTNS from June 30, 2011, to October 8, 2015, were retrospectively reviewed for demographics, copay, travel distance, employment status, history, symptoms, and treatments used before, during, and after PTNS. Pearson chi-square test, Fisher exact test, Wilcoxon rank and paired t test were performed. RESULTS: Of 113 patients (mean age 75 +/- 12 years), most were women (65.5%), married (78.1%), and retired or unemployed (80.2%). The median distance to the clinic was 8.1 mi, and the median copay was $0. The most common indication for PTNS was nocturia (92.9%) followed by OAB with urgency urinary incontinence (75.2%) and urinary urgency and/or frequency (24.8%). Prior treatments included anticholinergics (75.2%), mirabegron (36.6%), behavioral modification (29.2%), pelvic floor physical therapy (18.6%), and others (19.5%). Patients completed a mean of 10.5 +/- 3 of 12 planned weekly PTNS treatments. Of 105 patients, 40 (38.1%) used concomitant treatments (most commonly anticholinergics). Of 87 patients, 62 (71.3%) had decreased symptoms at 6 weeks, and of 85 patients, 60 (70.6%) had decreased symptoms at 12 weeks. The majority (82; 75.6%) completed all 12 weekly treatments and 45 (54.9%) completed 3 (median) monthly maintenance treatments. The most common reason for noncompliance was lack of efficacy. Visit copay, employment status, and distance to the clinic were not associated with failure to complete weekly treatments or progression to monthly maintenance. CONCLUSION: Although most patients' symptoms decreased after weekly PTNS, nonadherence to maintenance and lack of efficacy may limit long-term feasibility. Copay and distance traveled were not associated with noncompliance. PMID- 29196073 TI - Antithymocyte Globulin: Steps Toward Individualized Dosing. PMID- 29196072 TI - Social involvement issues in patients with Becker muscular dystrophy: A questionnaire survey of subjects from a patient registry. AB - BACKGROUND: Little is known about the relationship between Becker Muscular Dystrophy (BMD) and developmental problems, school life, employment, and mental problems. We aimed to clarify whether BMD is a risk factor for developmental disorders, problematic behavior, psychiatric diseases, and other social difficulties in school life and employment. METHODS: Adults with genetically or immunohistochemically confirmed BMD from the Registry of Muscular Dystrophy in Japan (REMUDY) were asked to complete a questionnaire regarding patient history, school life, employment, and mental problems. RESULTS: In total, 125 (68.3%) of 183 participants with BMD (median age, 37.2 years) completed the questionnaire. Of these, ten had developmental disorders (mental retardation, autism, and speech disturbance). Fifty-eight (44%) experienced bullying in school, and 39 felt the reason for bullying was physical handicap. Sixteen participants experienced problematic behavior such as cutting class, domestic violence, violent incidents, suicide attempts, or self-mutilation. Employment histories were noted by 92 (73%), of whom 15 could not continue to work due to physical handicaps. Fifteen participants had psychiatric disorders, with 5, 3 and 1 having neurosis, depression, and bipolar disorder, respectively. The other 6 participants with psychiatric disorders did not specify their diagnoses. Patients carrying a Dp140 expression change had significantly more incidences of developmental disorders, but not bullying, problematic behavior, workplace difficulties, or psychiatric disorders. CONCLUSIONS: Patients with BMD risk bullying and workplace difficulties, as well as developing psychiatric disorders. Parents, teachers, and supporters should be mindful of the daily environment of BMD patients and provide support to help them cope with stress. PMID- 29196074 TI - Acute Kidney Injury in Pediatric Patients Receiving Allogeneic Hematopoietic Cell Transplantation: Incidence, Risk Factors, and Outcomes. AB - Acute kidney injury (AKI) is a common adverse event after hematopoietic cell transplantation (HCT). AKI is associated with early death or chronic kidney disease among transplant survivors. However, large-scale pediatric studies based on standardized criteria are lacking. We performed a retrospective analysis of 1057 pediatric patients who received allogeneic HCT to evaluate the incidence and risk factors of AKI according to AKI Network criteria within the first 100 days of HCT. We also determined the effect of AKI on patient survival. The 100-day cumulative incidences of all stages of AKI, stage 3 AKI, and AKI requiring renal replacement therapy (RRT) were 68.2% +/- 1.4%, 25.0% +/- 1.3%, and 7.6% +/- .8%, respectively. Overall survival at 1 year was not different between patients without AKI and those with stage 1 or 2 AKI (66.1% versus 73.4% versus 63.9%, respectively) but was significantly different between patients without AKI and patients with stage 3 AKI with or without RRT requirement (66.1% versus 47.3% versus 7.5%, respectively; P < .001). Age, year of transplantation, donor type, sinusoidal obstruction syndrome (SOS), and acute graft-versus-host disease (GVHD) were independent risk factors for stages 1 through 3 AKI. Age, donor, conditioning regimen, number of HCTs, SOS, and acute GVHD were independent risk factors for AKI requiring RRT. Our study revealed that AKI was a prevalent adverse event, and severe stage 3 AKI, which was associated with reduced survival, was common after pediatric allogeneic HCT. All patients receiving allogeneic HCT, especially those with multiple risk factors, require careful renal monitoring according to standardized criteria to minimize nephrotoxic insults. PMID- 29196075 TI - Outcomes after Allogeneic Transplant in Patients with Wiskott-Aldrich Syndrome. AB - Wiskott-Aldrich syndrome (WAS) is a rare X-linked disorder characterized by a triad of immunodeficiency, eczema, and thrombocytopenia. Currently, hematopoietic stem cell transplantation (HSCT) is the most reliable curative treatment with excellent results for patients with HLA-matched family or unrelated donors. However, even after fully myeloablative preparative regimens, mixed donor chimerism is a potential concern. We performed a retrospective chart review of 12 children who underwent allogeneic HSCT for WAS to report our experience. The median age at transplant was 10.5 months (range, 3 to 39). The median nucleated cell dose from the marrow was 4.55 * 109/kg (range, .3 to 7.9). The median times to neutrophil and platelet engraftment were 19 days (range, 13 to 27) and 18.5 days (range, 12 to 31), respectively. The rate of overall survival was 92% with median follow-up of 67 months (range, 3 to 146). Two patients developed grade IV acute graft-versus-host disease, and 1 died on day +99. Five of 12 patient's (42%) had mixed donor chimerism (range, 12% to 85%) at day +180. None of the pretransplant patient parameters was predictive of mixed chimerism. Nonetheless, of these 5 patients, 2 had normalization of the platelet count despite the mixed chimerism, 2 had full donor chimerism after receiving a second transplant with the same donor, and 1 remains transfusion dependent awaiting a second transplant. Hence, even with a significant rate of mixed chimerism, HSCT provides substantial benefit to WAS patients, with excellent overall survival. PMID- 29196076 TI - Experiences and Decision Making in Hematopoietic Stem Cell Transplant in Sickle Cell Disease: Patients' and Caregivers' Perspectives. AB - Sickle cell disease (SCD) is one of the most commonly inherited hemoglobin disorders that has a significant impact on quality of life, increased childhood morbidity, and premature mortality. Currently, hematopoietic stem cell transplant (HSCT) is the only treatment with a curative intent. The objective of this study was to determine patients' and caregivers' knowledge of HSCT, the factors influencing the decision to pursue HSCT, their experiences, and the impact of a successful HSCT on their daily living. At Children's Healthcare of Atlanta, we conducted a qualitative study using a semistructured interview guide of patient caregiver dyads and 2 focus-group sessions of adult long-term survivors of HSCT to elicit key factors in decision making, their experiences with HSCT, and the impact of HSCT. Interviews and focus-group sessions were recorded and transcribed verbatim. Transcripts were coded and analyzed for emerging themes using NVivo 10.0. We enrolled 11 patient-caregiver dyads (n = 6, female patients; n = 10, mothers) in the qualitative interviews and 2 focus groups with 5 (n = 2, females) and 7 (n = 3, females) participants in each group, respectively. Our analysis revealed 3 prominent themes: (1) factors and concerns influencing HSCT decision making; (2) HSCT experiences; and (3) impact of HSCT on daily life. Participants reported that progression of disease-related complications and availability of a matched donor strongly influenced the decision to pursue HSCT. Although patients and caregivers had to deal with the arduous process of HSCT and transplant related morbidities, participants were satisfied with their decision and expressed no decisional regrets. Decision making for HSCT for patients with SCD is a complex process. Understanding the key influential factors in decision making and the impact HSCT has on these patients and their families will generate crucial insights that can guide the care of future patients and research studies. PMID- 29196077 TI - Impact of a Low CD34+ Cell Dose on Allogeneic Peripheral Blood Stem Cell Transplantation. AB - Although the CD34+ cell dose in allogeneic peripheral blood stem cell transplantation (PBSCT) is considered to be associated with transplantation outcomes, a lower acceptable threshold has not been defined. We retrospectively analyzed 2919 adult patients with hematologic malignancies who underwent related PBSCT in Japan between 2001 and 2014. According to the number of CD34+ cells in the graft, we categorized 2494 patients in the standard group (2 to 5 * 106 cells/kg), 377 patient in the low group (1 to 2 * 106 cells/kg), and 48 patients in the very low group (<1 * 106 cells/kg). Compared with the standard group, the low and very low groups showed delayed neutrophil recovery (93.8%, 89.5%, and 78.3%, respectively at day +28; P < .001) and platelet recovery (69.3%, 53.0%, and 45.5%, respectively at day +28; P < .001). The 2-year overall survival (OS) in the 3 groups was 45.5%, 45.3%, and 29.8%, respectively, with inferior survival in the very low group. However, a higher percentage of high-risk patients may account for the inferior survival in the very low group, and no significant difference in OS was found in a multivariate analysis. There were no differences in relapse, nonrelapse mortality, or the development of graft-versus-host disease among the 3 groups. In conclusion, allogeneic PBSCT with low CD34+ cell doses of 1 to 2 * 106 cells/kg gives acceptable results, whereas further investigations are needed to evaluate the effects of lower doses of <1 * 106 cells/kg owing to the smaller number and the higher percentage of patients with adverse prognostic factors in this cohort. PMID- 29196078 TI - Allogeneic Stem Cell Transplantation for Myelodysplastic Syndrome Patients with a 5q Deletion. AB - The deletion (5q) karyotype (del [5q]) in patients with myelodysplastic syndrome (MDS) is the most common karyotypic abnormality in de novo MDS. An increased number of blasts and additional karyotypic abnormalities (del [5q]+) are associated with a poor outcome. We analyzed the outcome of allogeneic hematopoietic cell transplants (HCT) in patients suffering from MDS with only del (5q) or del (5q)+ . A total of 162 patients, of median age 54 years (range, 9 to 73), having MDS and del (5q) abnormalities received HCT from identical siblings (n = 87) or unrelated donors (n = 75). The cumulative incidence of nonrelapse mortality and relapse incidence at 4 years was 29% (95% CI, 22 to 36) and 46% (95% CI, 38 to 54), whereas the estimated 4 year survival, relapse-free and overall, was 25% (95% CI, 18 to 33) and 30% (95% CI, 23 to 38), respectively. In a multivariate analysis patients with del (5q) and a blast excess displayed poorer survival (hazard ratio, 2.38; 95% CI, 1.44 to 3.93; P < .001), whereas female recipient sex resulted in improved survival (hazard ratio, .61; 95% CI, .41 to .90; P = .01). We conclude that allogeneic HCT can cure a subset of patients with MDS and a del (5q) abnormality. PMID- 29196079 TI - Burnout, Moral Distress, Work-Life Balance, and Career Satisfaction among Hematopoietic Cell Transplantation Professionals. AB - A projected shortage of hematopoietic cell transplantation (HCT) health professionals was identified as a major issue during the National Marrow Donor Program/Be The Match System Capacity Initiative. Work-related distress and work life balance were noted to be potential barriers to recruitment/retention. This study examined these barriers and their association with career satisfaction across HCT disciplines. A cross-sectional, 90-item, web-based survey was administered to advanced practice providers, nurses, physicians, pharmacists, and social workers in 2015. Participants were recruited from membership lists of 6 professional groups. Burnout (measured with the Maslach Burnout Inventory subscales of emotional exhaustion and depersonalization) and moral distress (measured by Moral Distress Scale-Revised) were examined to identify work-related distress. Additional questions addressed demographics, work-life balance, and career satisfaction. Of 5759 HCT providers who received an individualized invitation to participate, 914 (16%) responded; 627 additional participants responded to an open link survey. Significant differences in demographic and practice characteristics existed across disciplines (P < .05). The prevalence of burnout differed across disciplines (P < .05) with an overall prevalence of 40%. Over one-half of pharmacists had burnout, whereas social workers had the lowest prevalence at less than one-third. Moral distress scores ranged from 0 to 336 and varied by discipline (P < .05); pharmacists had the highest mean score (62.9 +/- 34.8) and social workers the lowest (42.7 +/- 24.4). In multivariate and univariate analyses, variables contributing to burnout varied by discipline; however, moral distress was a significant contributing factor for all providers. Those with burnout were more likely to report inadequate work-life balance and a low level of career satisfaction; however, overall there was a high level of career satisfaction across disciplines. Burnout, moral distress, and inadequate work-life balance existed at a variable rate in all HCT disciplines, yet career satisfaction was high. These results suggest specific areas to address in the work environment for HCT health professionals, especially the need for relief of moral distress and a greater degree of personal time. As the creation of healthy work environments is increasingly emphasized to improve quality care and decrease costs, these findings should be used by HCT leadership to develop interventions that mitigate work-related distress and in turn foster recruitment and retention of HCT providers. PMID- 29196082 TI - Feasible Optimization of Stereotactic Ablative Radiotherapy Dose by Tumor Size for Stage I Non-small-cell Lung Cancer. AB - INTRODUCTION: The purpose of this study was to assess the effect of dose escalation of stereotactic ablative radiotherapy (SABR) by investigating the long term clinical outcomes of SABR for stage I non-small-cell lung cancer (NSCLC). METHODS: A retrospective analysis was performed on a total of 169 patients with 178 lesions of stage I NSCLC treated with SABR at a single institution from June 2000 to May 2015. The standard dose scheme for SABR was 48 Gy in 4 fractions during the early period of the analysis, but it was escalated to 60 Gy in 4 fractions from June 2009. All failures were recorded over the follow-up period. RESULTS: Median follow-up time was 32 months. The 5-year overall survival rate was 46.7%, and the actuarial local control rate was 79.3%. Tumor size was an independent prognostic factor for survival. No relapse occurred in tumors <= 2 cm irrespective of SABR dose. Escalated doses of approximately 60 Gy in 4 fractions (biologically effective dose [BED] = 150 Gy10) achieved higher local control compared with 48 Gy in 4 fractions (BED = 106 Gy10) (76.2% vs. 60.6%) at 5-year follow-up (P = .022) in tumors > 2 cm. There were no differences in treatment related toxicities between the dose groups. Major failures consisted of distant metastasis to another lung parenchyma. CONCLUSION: SABR provides satisfactory long-term local control and high overall survival in medically inoperable stage I NSCLC. Tumors <= 2 cm had no local recurrence regardless of dose; whereas for tumors > 2 cm, an escalated BED of approximately 150 Gy10 provided significantly higher local tumor control. PMID- 29196081 TI - Prognostic Impact of Donor Source on Allogeneic Hematopoietic Stem Cell Transplantation Outcomes in Adults with Chronic Myelomonocytic Leukemia: A Nationwide Retrospective Analysis in Japan. AB - Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a curative therapeutic option for patients with chronic myelomonocytic leukemia (CMML). We retrospectively compared the post-transplantation outcomes of 159 patients with CMML who underwent allo-HSCT using 4 types of donor sources: HLA-matched related donor graft, unrelated bone marrow (U-BM), unrelated cord blood (U-CB), and HLA mismatched related donor graft. The median patient age at allo-HSCT was 54 years (range, 16 to 75 years). In multivariate analyses, the use of HLA-matched related donor grafts correlated with better overall survival than U-BM (hazard ratio [HR], 2.05; 95% confidence interval [CI], 1.21 to 3.48; P = .008), U-CB (HR, 3.80; 95% CI, 2.07 to 6.95; P < .001), or HLA-mismatched related donor grafts (HR, 6.18; 95% CI, 2.70 to 14.15; P < .001). Mortality after the relapse or progression of CMML did not significantly differ among the 4 types of donor source. Transplantation-related mortality was highest in recipients of U-CB (HR, 3.32; 95% CI, 1.33 to 8.26; P = .010). In patients with CMML, allo-HSCT using an alternative donor may contribute to durable remission; however, further improvements in transplantation-related mortality are required for this type of transplantation. PMID- 29196083 TI - The Good and the Bad About the 2017 American College of Physicians Osteoporosis Guidelines. AB - PURPOSE: The American College of Physicians (ACP) published a set of guidelines on how to prevent fractures in men and women with low bone density or osteoporosis. As the population ages, the overall risk of fractures increases, thus burdening the health care system. These guidelines review current evidence for osteoporosis management, providing an update to the previous 2008 ACP's guidelines. METHODS: The ACP put forth 6 recommendations addressing the complexities in osteoporosis management based on evidence available through October 2016 with a focus on bisphosphonates, calcium, vitamin D, and estrogen. Evidence was graded according to recommended strength by using the ACP standard methods. FINDINGS: The ACP recommends anti-osteoporosis therapy with 1 of 3 bisphosphonates (alendronate, risedronate, or zoledronic acid) or denosumab in patients with osteoporosis, while excluding anabolic therapies, and recommends against raloxifene. Although bisphosphonates are the mainstay of treatment, anabolic therapy and raloxifene may be used in specific situations. Pharmacologic therapy is recommended for 5 years, oversimplifying length of therapy and failing to promote an individualized patient-centered care approach. Moreover, abrupt discontinuation of denosumab is associated with a decline in bone mineral density (BMD), which must be addressed. Routine monitoring of BMD by dual x-ray absorptiometry is not endorsed during treatment, which leads to underrecognition of management issues. Pharmacologic treatment with bisphosphonates for male osteoporosis is recommended, although therapies such as denosumab and teriparatide are excluded. Finally, the ACP recommends treatment for women aged >=65 years at high risk for fracture with osteopenia after a discussion of patient preferences, fracture risk profile, and medications. IMPLICATIONS: Osteoporosis management is complex. The 2017 ACP guidelines address challenges faced by clinicians but oversimplify more complex issues. These are among a number of guidelines that are available for osteoporosis management, which may be used in combination with other sources to assist clinicians with diagnostic and management strategies. PMID- 29196080 TI - Outcomes after Allogeneic Stem Cell Transplantation in Patients with Double-Hit and Double-Expressor Lymphoma. AB - Double-hit lymphomas (DHLs) and double-expressor lymphomas (DELs) are associated with resistance to frontline and salvage immunochemotherapy, as well as autologous stem cell transplantation (SCT). We hypothesized that allogeneic SCT (alloSCT) could overcome the chemoresistance associated with DEL/DHL. We retrospectively studied the impact of DEL/DHL status in a multicenter cohort of patients who underwent alloSCT for relapsed/refractory (rel/ref) aggressive B cell non-Hodgkin lymphoma (B-NHL). Seventy-eight patients transplanted at 3 centers in whom tumor tissue was available for immunohistochemistry and fluorescence in situ hybridization were enrolled; 47% had DEL and 13% had DHL. There were no significant differences in 4-year progression-free (PFS) or overall survival (OS) between patients with DEL compared with patients without DEL (PFS 30% versus 39%, P = .24; OS 31% versus 49%, P = .17) or between patients with DHL compared with patients without DHL (PFS 40% versus 34%, P = .62; OS 50% versus 38%, P = .46). The lack of association between DEL or DHL and outcome was confirmed in multivariable models, although inadequate sample size may have limited our ability to detect significant differences. In our cohort alloSCT produced durable remissions in patients with rel/ref aggressive B-NHL irrespective of DEL and DHL status, justifying its consideration in the treatment of patients with rel/ref DEL/DHL. PMID- 29196084 TI - Characteristics Associated with the Choice of First Injectable Therapy Among US Patients With Type 2 Diabetes. AB - PURPOSE: The objective of this retrospective observational study was to describe and identify clinical and demographic characteristics associated with the choice of first injectable therapy (glucagon-like peptide-1 receptor agonist [GLP-1-RA] or basal insulin) among patients with type 2 diabetes mellitus (T2DM). METHODS: This analysis included adults naive to injectable therapy with T2DM who initiated a GLP-1-RA or basal insulin (index date) between November 2014 and February 2016 using data from the Practice Fusion Electronic Health Record database. Patients with T2DM, >=1 office visit between 6 and 18 months before the index date, and with >=1 glycosylated hemoglobin (HbA1c) result in the 6-month preindex (baseline) period were included. A generalized boosted regression model was used to determine the patient characteristics most influential in the selection of a GLP-1-RA or basal insulin as first injectable therapy. Sensitivity analysis was performed by using bootstrapped logistic regression. FINDINGS: The study included 3546 and 7507 GLP-1-RA and basal insulin initiators, respectively. At baseline, GLP-1-RA initiators were significantly younger (mean, 58 vs 63 years), had lower HbA1c values (mean, 8.2% vs 9.1%), lower Diabetes Complications Severity Index (DCSI) scores (mean, 1.0 vs 1.7), and a higher body mass index (BMI) (mean, 36 vs 33 kg/m2) compared with basal insulin initiators. Variables selected by using the generalized boosted regression model with the highest relative importance (>=5%) in the selection of GLP-1-RA or basal insulin were HbA1c level (20.43%), BMI (17.73%), age (12.21%), prior prescription of a sodium-glucose cotransporter-2 inhibitor (9.17%), and DCSI score (8.39%). The same variables, as well as race, were selected by using stepwise logistic regression in all the bootstrapped samples. Patients who were older (adjusted odds ratio [OR], 0.975 [95% CI, 0.971 0.979]) and had higher HbA1c values (OR, 0.741 [95% CI, 0.721-0.761]) and DCSI scores (OR, 0.870 [95% CI, 0.848-0.892]) were significantly less likely to be prescribed a GLP-1-RA compared with basal insulin. Patients with higher BMI (OR, 1.046 [95% CI, 1.040-1.053]) and previous prescription of sodium-glucose cotransporter-2 inhibitors (OR, 2.633 [95% CI, 2.224-2.982]) were significantly more likely to be prescribed a GLP-1-RA. IMPLICATIONS: The clinically relevant differences observed between the 2 patient populations suggest that GLP-1-RAs and basal insulin are prescribed to different types of patients with T2DM. Examining patients' demographic and clinical characteristics may be important in assisting physicians in the choice of patient-centered injectable treatment regimens. PMID- 29196085 TI - Technology Interventions for Nonadherence: New Approaches to an Old Problem. AB - Nonadherence to asthma medications is well recognized. Interventions to improve adherence, however, have been only moderately successful and are not often adopted because of limited provider time, training, or institutional support. The potential for mobile communication technology to improve adherence has gathered sharply growing interest. Technology-based adherence tracking devices have been in existence for almost 3 decades, but have only recently reached a level of reliability and utility to be considered in allergy practice. Adherence intervention technology includes smartphones, apps, and a growing number of potential new asthma uses such as inhaler technique assessment, portable fractional exhaled nitric oxide devices, and GPS activity trackers with environmental contaminant alerts. As technology has advanced, new capability has emerged including drawing information from electronic health records to tailor automated interventions, give real-time feedback to patients, leverage incentives, utilize predictive logarithms that identify patients at exacerbation risk, and initiate an intervention. Technology development moves faster than clinical trial tests of these new interventions, and gaps in evidence will need to be closed. As researchers establish cost effectiveness, sustainability, and patient and provider acceptance, technology-based adherence intervention systems are likely to be increasingly adopted into small and large practice settings.

AB - BACKGROUND: Left ventricular (LV) dysfunction develops during LV hypertrophy and particularly during tachycardia. Thus we investigated the effects of heart rate (HR) reduction with ivabradine, an If-channel blocker, on LV twist and untwist which represents myocardial deformation occurring during the overall systole and diastole and therefore provide valuable evaluation of global LV systolic and diastolic function. METHODS: Eight chronically instrumented pigs receiving continuous angiotensin II infusion during 28days to induce chronic hypertension and LV hypertrophy. Measurements were performed at Days 0 and 28 after stopping angiotensin II infusion in the presence and absence of ivabradine. RESULTS: At Day 0, reducing HR from 75+/-3 to 55+/-2beats/min with ivabradine did not affect LV twist but slowed LV untwist along with an increase in LV end-diastolic pressure. At Day 28, LV posterior and septal wall thickness as well as the estimated LV mass increased, indicating LV hypertrophy. LV twist and untwist were significantly reduced by 33+/-4% from 16+/-1 degrees and 32+/-6% from -154+/-9 degrees /s, respectively, showing global LV systolic and diastolic dysfunction. In this context, ivabradine decreased HR by 25% from 86+/-5beats/min and significantly improved LV twist from 11+/-1 to 14+/-1 degrees and LV untwist from -104+/-8 to -146+/-5 degrees /s. CONCLUSIONS: Administration of ivabradine during chronic hypertension and LV hypertrophy improved LV twist and untwist. This further supports the beneficial effect of this drug on both LV systolic and diastolic function during the development of LV hypertrophy. PMID- 29196089 TI - Atrial fibrillation ablation with the second generation cryoballoon: Multicenter propensity score matched comparison between freezing strategies. AB - BACKGROUND: Second generation cryoballoon (CB-A) ablation is highly effective in achieving pulmonary vein (PV) isolation and freedom from atrial fibrillation (AF). However, the ideal freezing strategy is still under debate. Our objective was to investigate the efficacy and outcome between different freezing strategies used with the CB-A in a multicenter, matched population. METHODS: From a total cohort of 1018 patients having undergone CB-A ablation for drug-refractory AF, 673 patients with follow-up >=6months were included and stratified according to the applied freezing strategy: bonus freeze (BF) versus single freeze (SF). Final population of 256 BF patients was compared with 256 propensity-score matched SF patients. RESULTS: BF strategy consisted of 3 different protocols: 3cycles of 180s; 2cycles of 240s; and cycles of 240s followed by 180s in 99/256 (39%); 42/256 (16%); and 115/256 (45%) patients, respectively. SF approach included cycles of 240s in 23/256 (9%), and 180s in 233/256 (91%) patients. Electrical isolation could be achieved in all PVs by both protocols, with shorter procedure and fluoroscopy times in the SF group (mean 106 vs 65min, and 18 vs 14min, respectively, P<0.001). Phrenic nerve palsy persisted after discharge in a total of 11 patients (2.1%): 4 (1.6%) in the BF group vs 7 (2.7%) in the SF group, P=0.5. AF-free survival was similar between the 2 groups during follow-up (mean 18+/-10months) (log rank, P=0.6). CONCLUSIONS: CB-A ablation showed equal efficacy and outcome between SF and BF strategy. PMID- 29196090 TI - Diagnostic performance of stress perfusion cardiac magnetic resonance for the detection of coronary artery disease: A systematic review and meta-analysis. AB - INTRODUCTION: The purpose of this study was to investigate the accuracy of qualitative stress perfusion cardiac magnetic resonance (CMR) to diagnose ischemia-causing lesions according to different definitions of significant coronary artery disease (CAD), and magnetic field strength. METHODS: We searched PubMed, Web of Science, and the Cochrane Library for studies evaluating diagnostic performance of qualitative stress perfusion CMR for diagnosis of CAD versus coronary angiography or fractional flow reserve (FFR) from inception to 10 September 2017. We used hierarchical models to synthesize the available data. RESULTS: Sixty-seven studies (7113 patients) met the inclusion criteria. The patient-based analysis of studies using FFR as the reference standard demonstrated a mean sensitivity of 0.90 (95% confidence interval [CI], 0.85-0.93) and a mean specificity of 0.85 (95% CI, 0.80-0.89). The patient-based analyses for detecting coronary stenosis >=50% and coronary stenosis >=70% at 1.5T and for detecting coronary stenosis >=50% and coronary stenosis >=70%, at 3T, demonstrated a mean sensitivity of 0.82 (95% CI, 0.79-0.84), 0.86 (95% CI, 0.83 0.89), 0.90 (95% CI, 0.82-0.95), and 0.91 (95% CI, 0.79-0.96), respectively; with a mean specificity of 0.75 (95% CI, 0.71-0.80), 0.77 (95% CI, 0.71-0.81), 0.79 (95% CI, 0.69-0.86), and 0.74 (95% CI, 0.59-0.85). CONCLUSION: Qualitative stress perfusion CMR has high accuracy for the diagnosis of CAD, irrespective of the reference standard and the magnet strength. Studies using FFR as the reference standard had higher diagnostic accuracy on a patient level compared to studies using coronary angiography, with a notable difference in specificity. PMID- 29196091 TI - Minimally invasive percutaneous transluminal renal artery stenting. AB - BACKGROUND: Minimally invasive percutaneous transluminal renal artery stenting (MIPTRS) is a method that prevents complications to the greatest extent possible. The present study aimed to investigate the safety and efficacy of MIPTRS performed in cases of renal artery stenosis with an estimated glomerular filtration rate (eGFR)<=45mL/min. METHODS: Cases of patients who underwent MIPTRS at our hospital between December 2010 and June 2015 in whom eGFR was <=45mL/min were retrospectively analysed. MIPTRS was performed as follows: 1) using a 4Fr sheathless guiding catheter in a trans-radial approach and 2) using a guiding catheter non-touch technique. The amount of contrast agent used was maintained at <=10mL with 3) carbon dioxide enhancement and 4) intravascular ultrasound guide stenting, and 5) a distal protection device was used. RESULTS: MIPTRS was performed in 22 patients (32 lesions). The pre-MIPTRS creatinine level and eGFR were 2.01+/-0.88mg/dL and 29.2+/-9.0mL/min/1.73m2, respectively. On postoperative day 2, they were 1.78+/-0.73mg/dL and 35.1+/-12.3mL/min/1.73m2; at 1month after the procedure, they were 1.80+/-0.74mg/dL and 33.3+/-12.3mL/min/1.73m2. Creatinine level did not change significantly, but eGFR was significantly elevated after versus before the procedure, both 2days later (p<0.01) and 1month later (p<0.05). CONCLUSION: The results of this study demonstrated the usefulness of MIPTRS for protecting renal function. This method can be safely used in patients with decreased renal function.

PMID- 29196093 TI - Sonic hedgehog regulates the pathfinding of descending serotonergic axons in hindbrain in collaboration with Wnt5a and secreted frizzled-related protein 1. AB - Previous studies have demonstrated that both Wnt5a and Sonic hedgehog (Shh) are involved in regulating the pathfinding of descending serotonergic (5-HT, 5 hydroxytryptamine) axons in an opposite manner in the brainstem. Shh and Wnt signaling pathways interact to guide post-crossing commissural axons, where Shh acts as a repellent directly and shaping the Wnt gradient indirectly by regulating the gradient expression of the frizzled-related protein 1 (Sfrp1). Whether such a mechanism functions in descending 5-HT axon guidance remains unknown. Here, we found that the core components of the Shh and Wnt planar cell polarity signaling pathways are expressed in caudal 5-HT neurons, and the expression gradients of Shh, Sfrp1, and Wnt5a exist simultaneously in hindbrain. Dunn chamber assays revealed that Sfrp1 suppressed the attractive Wnt gradient. Moreover, we found that Shh overexpression led to pathfinding defects in 5-HT axon descending, and the axonal pathfinding defects could be partially rescued by administration of an Sfrp1 antagonist in vivo. Biochemical evidence showed Shh overexpression upregulated the expression of the Sfrp1 gene and interrupted Wnt5a binding to Frizzled-3. Taken together, our results indicate that Shh, Sfrp1, and Wnt5a collaborate to direct the pathfinding of descending 5-HT axons in the brainstem. PMID- 29196094 TI - [FREGAT: French clinico-biological database dedicated to esogastric cancers]. AB - Even though esogastric cancers are estimated at 1.5 million new cases worldwide with an expected 2.11 million new cases by 2025, prognosis remains poor and research is unsatisfactory compared to other cancers. There is an urgent need to intensify research via innovative and ambitious programs to improve patient's survival and quality of life. Incidence of esogastric cancers is particularly high in France, and the creation of a national clinicobiological database prospectively collecting epidemiological, human and social, clinical, pathological, biological data, sustained by biobanks of blood and tissues, is a critical point to improve research and care for these cancers considering all determinants of the disease with a more integrated approach. FREGAT clinicobiological database, funded and labeled by the French NCI in 2012, gathers the vast majority of university hospitals and cancer centers in France. This research relies on preexisting networks ensuring its efficacy and quality. Beyond significant increase of inclusions opened since January 2015, the establishment of public multiprivate industrial partnerships and creation of numerous French and European scientific projects, make FREGAT a decisive tool for research on esogastric cancers. PMID- 29196095 TI - Prognostic value of combining a quantitative image feature from positron emission tomography with clinical factors in oligometastatic non-small cell lung cancer. AB - BACKGROUND AND PURPOSE: Oligometastatic non-small cell lung cancer (NSCLC) is a heterogeneous condition with few known risk stratification factors. A quantitative imaging feature (QIF) on positron emission tomography (PET), gray level co-occurrence matrix energy, has been linked with outcome of nonmetastatic NSCLC. We hypothesized that GLCM energy would enhance the ability of models comprising standard clinical prognostic factors (CPFs) to stratify oligometastatic patients based on overall survival (OS). MATERIALS AND METHODS: We assessed 79 patients with oligometastatic NSCLC (<=3 metastases) diagnosed in 2007-2015. The primary and largest metastases at diagnosis were delineated on pretreatment scans with GLCM energy extracted using imaging biomarker explorer (IBEX) software. Iterative stepwise elimination feature selection based on the Akaike information criterion identified the optimal model comprising CPFs for predicting OS in a multivariate Cox proportional hazards model. GLCM energy was tested for improving prediction accuracy. RESULTS: Energy was a significant predictor of OS (P = 0.028) in addition to the selected CPFs. The c-indexes for the CPF-only and CPF + Energy models were 0.720 and 0.739. CONCLUSIONS: Incorporating Energy strengthened a CPF model for predicting OS. These findings support further exploration of QIFs, including markers of the primary tumor vs. those of the metastatic sites. PMID- 29196096 TI - Effects of isolated tobacco alkaloids and tobacco products on deprivation-induced food intake and meal patterns in rats. AB - The ability of smoking to reduce body weight serves as motivation for continued smoking. It is unclear to what extent non-nicotine constituents in cigarettes are contributing to the weight-reducing effect of smoking. The purpose of the current study was to examine the effects of nicotine and four minor tobacco alkaloids (nornicotine, cotinine, anatabine, and anabasine) on food intake, one of the key regulators of body weight. In addition, a smokeless tobacco extract (STE) and e cigarette (EC) refill liquid were used to model the effects of actual tobacco product exposure on food intake. Male Holztman rats were trained to lever press for food pellets during daily 2h sessions in operant chambers. In Experiment 1, the effects of subcutaneous injections of saline, nicotine (0.25-1.00mg/kg), nornicotine (0.50-6.00mg/kg), cotinine (1.00-100.00mg/kg), anatabine (0.25 3.00mg/kg), and anabasine (0.50-4.00mg/kg) were assessed. In Experiment 2, rats from Experiment 1 were used to examine the effects of nicotine, STE, and EC liquid. All alkaloids, except cotinine, produced a dose-dependent reduction in overall food intake. The highest doses of all drugs significantly reduced latency and response rate to obtain the first pellet. At some doses, nicotine, anatabine, and nornicotine reduced food intake within the first 45min without compensatory increases in intake later in the session. STE and EC liquid produced dose dependent decreases in food intake similar to nicotine alone. These data suggest that minor tobacco alkaloids have appetite suppressant effects and warrant further investigation into their effects on body weight, energy intake, and energy expenditure under free-feeding conditions. However, findings with STE and EC liquid suggest that nicotine is the primary constituent in these products to affect food intake, whereas levels of minor alkaloids in these products may be too low to influence food intake. PMID- 29196098 TI - Exosomes and their role in the intercellular trafficking of normal and disease associated prion proteins. AB - Over the past decade, small extracellular vesicles called exosomes have been observed to harbour protein and genetic cargo that can assist in health and also cause disease. Many groups are extensively investigating the mechanisms involved that regulate the trafficking and packaging of exosomal contents and how these processes may be deregulated in disease. Prion diseases are transmissible neurodegenerative disorders and are characterized by the presence of detectable misfolded prion proteins. The disease associated form of the prion protein can be found in exosomes and its transmissible properties have provided a reliable experimental read out that can be used to understand how exosomes and their cargo are involved in cell-cell communication and in the spread of prion diseases. This review reports on the current understanding of how exosomes are involved in the intercellular spread of infectious prions. Furthermore, we discuss how these principles are leading future investigations in developing new exosome based diagnostic tools and therapeutic drugs that could be applied to other neurodegenerative diseases. PMID- 29196099 TI - DKK3 overexpression attenuates cardiac hypertrophy and fibrosis in an angiotensin perfused animal model by regulating the ADAM17/ACE2 and GSK-3beta/beta-catenin pathways. AB - AIMS: Cardiac pressure and humoral factors induce cardiac hypertrophy and fibrosis, which are characterized by increased stiffness, reduced contractility and altered perfusion. Angiotensin II (AngII) is well known to promote this pathology. Angiotensin-converting enzyme (ACE) 2, which cleaves AngII and forms Ang-(1-7), exerts protective anti-hypertrophy and anti-fibrosis effects. A disintegrin and metalloproteinase 17 (ADAM17), a membrane-bound enzyme reported to cleave ACE2, may participate in the pathological process of AngII perfusion induced heart damage. However, researchers have not clearly determined whether dickkopf-3 (DKK3) regulates the ADAM17/ACE2 pathway and, if so, whether DKK3 mediated regulation is related to the glycogen synthase kinase-3beta (GSK 3beta)/beta-catenin pathway. In this study, we explored whether DKK3 overexpression ameliorates the development of AngII-induced cardiac fibrosis and hypertrophy through the ADAM17/ACE2 and GSK-3beta/beta-catenin pathways. METHODS: Mice were injected with a DKK3-overexpressing adenovirus or vehicle and then infused with AngII or saline using subcutaneously implanted mini-pumps for four weeks. Hearts were stained with hematoxylin-eosin, Masson's trichrome and immunohistochemical markers for histology. Primary fibroblasts were treated with the adenovirus and AngII and then examined using western blotting, EdU (5-ethynyl 2'-deoxyuridine) assays and immunofluorescence. Additionally, siRNA silencing was performed to study the role of DKK3 and the involved pathways. RESULTS: AngII induced cardiac hypertrophy and interstitial and perivascular fibrosis were less severe in DKK3-overexpressing mice than in control mice. Moreover, the expression levels of fibrotic genes, such as collagen I and III, and the hypertrophic genes atrial natriuretic peptide (ANP) and beta-myosin heavy chain (beta-MHC) were decreased. DKK3 overexpression also exerted a protective effect by inhibiting ADAM17 phosphorylation, thus increasing ACE2 expression and subsequently promoting AngII degradation. Furthermore, this process was mediated by the inhibition of GSK-3beta and beta-catenin and decreased translocation of beta catenin to the nucleus. On the other hand, the DKK3 knockdown by siRNA achieved opposite results. CONCLUSION: DKK3 overexpression substantially alleviated AngII infusion-induced cardiac hypertrophy and fibrosis by regulating ADAM17/ACE2 pathway activity and inhibiting the GSK-3beta/beta-catenin pathway. PMID- 29196100 TI - Mathematical calculation of lifespan of transfused RBCs in sickle cell disease patients. AB - BACKGROUND: Transfusion of donor red blood cells (RBCs) remains an important part of management of sickle cell disease (SCD). However, the survival characteristics of transfused donor RBCs in SCD patients have not been well studied. We sought to calculate survival kinetics of transfused RBCs in SCD patients since it is unclear whether transfused RBCs get destroyed at faster rate as innocent bystander or persist longer due to decreased destruction capacity such as functional splenectomy. STUDY DESIGN: and methods Forty-one SCD patients who had undergone at least 3 RBC exchange procedures were inlcuded. Interval between the procedures, both pre-procedure and post procedure hematocrits, HbA% and HbS% were collected. We developed a mathematical model to calculate RBC lifespan for donor RBCs. RESULTS: Donor RBCs exhibited average lifespan of about 120days (121.1+/ 13.9 days), which was similar to reported survival of RBCs in normal recipients. However, significant variation between patients were observed with lifespan ranging from 75.6-148.5 days. Intrapersonal variations were small in most cases. CONCLUSION: The calculated survival of donor RBCs in SCD recipient, based on certain laboratory values, appears to be similar to that of normal recipient. However, inter-personal variations were large, suggesting different RBC kinetics in a subset of patients, which calls for further research to better understand underlying pathophysiology. This knowledge of RBC survival would be very helpful in individualized management of patients on chronic RBCx. PMID- 29196097 TI - The influence of tumour-derived extracellular vesicles on local and distal metastatic dissemination. AB - Extracellular vesicles (EVs) are key mediators of intercellular communication that have been ignored for decades. Tumour cells benefit from the secretion of vesicles as they can influence the behaviour of neighbouring tumour cells within the tumour microenvironment. Several studies have shown that extracellular vesicles play an active role in pre-metastatic niche formation and importantly, they are involved in the metastatic organotropism of different tumour types. Tumour-derived EVs carry and transfer molecules to recipient cells, modifying their behaviour through a process defined as "EV-driven education". EVs favour metastasis to sentinel lymph nodes and distal organs by reinforcing angiogenesis, inflammation and lymphangiogenesis. Hence, in this review we will summarize the main mechanisms by which tumour-derived EVs regulate lymph node and distal organ metastasis. Moreover, since some cancers metastasize through the lymphatic system, we will discuss recent discoveries about the presence and function of tumour EVs in the lymph. Finally, we will address the potential value of tumour EVs as prognostic biomarkers in liquid biopsies, specially blood and lymphatic fluid, and the use of these tools as early detectors of metastases. PMID- 29196101 TI - miR-135b-5p Promotes migration, invasion and EMT of pancreatic cancer cells by targeting NR3C2. AB - The exact mechanisms of metastasis for pancreatic cancer remain to be uncovered. This study aimed to elucidate the potential functional mechanism of miR-135b-5p in migration, invasion and epithelial-to-mesenchymal transition (EMT) of pancreatic cancer cells. By real-time PCR and analysis of GEO database, we determined the up-regulated expression of miR-135b-5p in pancreatic cancer tissues and cell lines. Clinically, highly expressed miR-135b-5p was closely related to advanced TNM stage, more lymph node metastasis, more distant metastasis and worse overall survival (OS) and disease-free survival (DFS). Functionally, Transwell assays indicated that miR-135b-5p was a promoter for migration and invasion of pancreatic cancer cells. Additionally, immunohistochemistry staining and Western blot showed that highly expressed miR 135b-5p accelerated EMT process of pancreatic cancer cells. Furthermore, a series of experiments and rescue experiments revealed that Nuclear Receptor Subfamily 3 Group C Member 2 (NR3C2) was the target of miR-135b-5p in pancreatic cancer cells, mediating the promotion effects of miR-135b-5p on the tumor cells migration, invasion and EMT. In conclusion, miR-135b-5p, maybe a novel therapeutic target for pancreatic cancer, promoted migration, invasion and EMT of pancreatic cancer cells by targeting NR3C2. PMID- 29196102 TI - Selective anticancer activity of the novel steroidal dihydropyridine spirooxindoles against human esophageal EC109 cells. AB - A series of small-molecule compounds built on steroidal dihydropyridine spirooxindoles has been reported previously. In this study, the compound 5l showed strong anti-cancer activity, especially in the esophageal cancer. Three esophageal squamous cell lines and paclitaxel-resistant cell line were investigated. The results demonstrated that compound 5l was most efficient in the EC109 cells, induced cell apoptosis through elevation of cellular ROS levels, caused G2/M phase arrest and mitochondrial dysfunction. Further study confirmed that the mechanism of 5l in esophageal cancer treatment was related to the Bcl-2 family and caspase receptor-mediated apoptotic pathway. PMID- 29196103 TI - Cyclin-dependent kinase inhibitor 3 (CDKN3) plays a critical role in prostate cancer via regulating cell cycle and DNA replication signaling. AB - Cyclin-dependent kinase inhibitor 3 (CDKN3) is proved to be associated with the progressing of many cancers. Whereas, its biological effects on prostate cancer (PC) are less understood. To investigate the functional mechanism of CDKN3 in PC, we examined the expression of CDKN3 in PC tissues and analyzed the disease free survival time of patients. We then transfected LNCaP and PC3 cells with siRNA CDKN3 to silence CDKN3, and transfected 22RV1 and VCaP cells with full length CDKN3 cDNA for CDKN3 over-expression. Cell growth of these transfected cells were analyzed using CCK-8 assay. And transfected LNCaP and PC3 cells were further submitted to cell cycle, apoptosis, invasion and endogenous protein expression assays. We found that CDKN3 was highly expressed in PC and negatively correlated with disease relapse. And CDKN3 positively control the cell proliferation in prostate carcinoma cell lines. Knockdown of CDKN3 significantly promoted G1 phase arrest, elevated apoptosis rates, and suppressed cell invasion in both LNCaP and PC3 cells. Moreover, in vivo data showed that knockdown of CDKN3 expression dramatically inhibited the PC3 tumor growth in nude mouse model. Gene set enrichment analysis (GSEA) showed that cell cycle and DNA replication signaling were related with elevated CDKN3 expression. And results of western blot showed that the depletion of CDKN3 down-regulated the expression levels of cell cycle- and DNA replication-related proteins. In conclusion, our results highlight the importance of CDKN3 in PC and provide new insights into diagnostics and therapeutics of the PC. PMID- 29196104 TI - Up-regulation of long noncoding RNA FALEC predicts poor prognosis and promotes melanoma cell proliferation through epigenetically silencing p21. AB - Accumulating evidences have suggested that focally amplified lncRNA on chromosome 1 (FALEC) serves as an oncogenic long non-coding RNA (lncRNA) and has been identified to be dysregulated in various tumors. However, the expression, clinical values, and biological function of FALEC in melanoma are still unknown. In this study we detected the expression level of FALEC in tumor tissues and cell lines and measured the prognostic value of FALEC for melanoma patients and the biological effects of FALEC on melanoma cell proliferation, cell cycle, and apoptosis. Our results indicated that FALEC was more highly expressed in melanoma tissues and cell lines than in non-neoplastic nevi tissues and normal cell lines. Moreover, functional assays showed that silenced FALEC suppressed the proliferation of melanoma cells, resulted in cell cycle arrest, and induced apoptosis. Mechanically, we discovered that FALEC boosted melanoma progression via epigenetically repressing p21 through recruiting EZH2 to the promoter of p21. Generally, our results suggested that FALEC acted as an oncogene in melanoma and had the potential to be a prognostic biomarker and therapeutic target for melanoma. PMID- 29196105 TI - Asiatic acid ameliorates hepatic ischemia/reperfusion injury in rats via mitochondria-targeted protective mechanism. AB - It has been proved that asiatic acid (AA) directly targets mitochondria and acts as a mild mitochondrial uncoupler. In this study, we aim to investigate the protective effects of AA against ischemia/reperfusion (I/R)-induced liver injury in rats and some underlying mechanisms involved were elucidated. The results showed that 50mg/kg AA pre-treatment significantly reduced I/R-induced liver damage, characterized by the decreased release of aspartate aminotransferase (AST) and TNF-alpha. Furthermore, AA pre-treatment dramatically inhibited the production of MDA and increased the hepatic SOD, catalase activities and GSH levels in liver tissue of I/R rats which indicated that AA ameliorated I/R induced liver damage by reducing oxidative stress. In isolated liver mitochondria in I/R rats, AA improved mitochondrial respiration, decreased mitochondrial MDA level, prevented I/R-induced drop of mitochondrial membrane potential (MMP) and increased ATP content, indicating the protective effect of AA against I/R-induced mitochondrial oxidative damage. In isolated liver mitochondria from normal rats, AA was found to effectively block succinate-driven H2O2 production no matter of the presence or absence of rotenone. In addition, AA showed a clear protective effect against anoxia/reoxygenation (A/R)-induced injury in isolated rat liver mitochondria when malate/glutamate were used as respiratory substrates. After AA treatment, mitochondrial respiratory dysfunction induced by A/R was ameliorated. Also, A/R-induced mitochondrial ROS generation was significantly inhibited by AA. In conclusion, AA can attenuate I/R-induced liver damage in rats and A/R-induced mitochondrial injury in isolated rat liver mitochondria by inhibiting oxidative stress and restoring mitochondrial function. Therefore, AA might have potential as a mitochondrial protective agent for use in clinical treatment of hepatic I/R injury.

Utilization of hemicellulosic fraction in lignocelluloses is crucial in economical production of lignocellulosic ethanol. However, this fraction has not efficiently been utilized by traditional yeast Saccharomyces cerevisiae. Genetically modified S. cerevisiae, which can utilize xylose, has several limitations including low ethanol yield, redox imbalance, and undesired metabolite formation similar to native xylose utilizing yeasts. Besides, xylose uptake is a major issue, where sugar transport system plays an important role. These genetically modified and wild-type yeast strains have further been engineered for improved xylose uptake. Various techniques have been employed to facilitate the xylose transportation in these strains. The present review is focused on the sugar transport machineries, mechanisms of xylose transport, limitations and how to deal with xylose transport for xylose assimilation in yeast cells. The recent advances in different techniques to facilitate the xylose transportation have also been discussed. PMID- 29196107 TI - Distribution of Smad mRNA and proteins in the rat brain. AB - Smad proteins are known to transduce the action of TGF-beta superfamily proteins including TGF-betas, activins, and bone morphogenetic proteins (BMPs). In this study, we examined the expression of Smad1, -2, -3, -4, -5, and -8 mRNA in the rat brain by means of RT-PCR and in situ hybridization (ISH). In addition, we examined the nuclear accumulation of Smad1, -2, -3, -5, and -8 proteins after intracerebroventricular injection of TGF-beta1, activin A, or BMP6 with immunohistochemistry to investigate whether TGF-beta, activin, and/or BMP activate Smads in the rat brain. RT-PCR analysis revealed that Smad1, -2, -3, -4, -5, and -8 mRNA was expressed in the brain and that the Smad3 and Smad8 mRNA differed in the expression level between brain regions. For example, there were high levels of expression of Smad3 mRNA in the cerebral cortex, caudate putamen/globus pallidus, and cerebellum, but low levels in the thalamus and midbrain. Expression of Smad8 mRNA was higher in the midbrain, cerebellum, and pons/medulla oblongata in comparison to the olfactory bulb, cerebral cortex, caudate putamen/globus pallidus, hippocampus/dentate gyrus, and thalamus. ISH signals for Smad1 mRNA were widely detected in the brain except for a small number of regions including the olfactory tubercle, posterior region of hypothalamus, and cerebellar nuclei. ISH signals for Smad2 mRNA were abundantly observed in several brain regions including the olfactory bulb, piriform cortex, basal ganglia, cingulate cortex, epithalamus, including the pineal gland and medial habenular nuclei, hypothalamus, inferior colliculi of the midbrain, and some nuclei in the pons, cerebellar cortex, and choroid plexus. ISH signals for Smad3 mRNA were also abundantly observed in several brain regions. Especially strong signals for Smad3 mRNA were observed in the olfactory tubercle, piriform cortex, basal ganglia, dentate gyrus, and cingulate cortex. ISH signals for Smad5 and Smad8 mRNA were restricted to a small number of brain regions, the signal intensity of which was weak. ISH signals for Smad4 mRNA were detected in all regions examined. Intracerebroventricular injection of activin A induced nuclear accumulation of Smad2 and Smad3 immunoreactivity in neurons. In contrast, intracerebroventricular injection of TGF-beta1 or BMP6 did not induce nuclear accumulation of the immunoreactivity for any Smad in neurons. These results suggest that activin-Smad signaling plays an important role in brain homeostasis. PMID- 29196108 TI - Leaflets and continual educational offerings led to increased coverage rate of newborn hearing screening in Akita. AB - OBJECTIVE: Newborn hearing screening (NHS) has been actively performed in Japan since 2001. The NHS coverage rate has increased each year in Akita Prefecture. We analyzed the details of the NHS program and how the Akita leaflets and the many educational offerings about the importance of NHS led to the high NHS coverage rate. METHODS: A retrospective study was conducted in liveborn newborns in hospitals and in clinics where hearing screening was performed from the program's beginning in 2001 through the end of 2015. We describe the chronological history of NHS. The outcome data of NHS were collected from our department and analyzed. RESULTS: From the founding of the program in 2001 to 2015, the live birth rate in Akita continually declined. Nevertheless, the number of infants receiving NHS rose each year. Since 2012, the coverage rate of NHS has been over 90%. From 2001 to 2015, 75,331 newborns constituted the eligible population for the NHS program. Since 2012, the number of NHS tests has stabilized. We prepared educational leaflets for Akita Prefecture early in 2002. We also provided many educational classes about the importance of NHS for not only pregnant women but also professionals including obstetricians and gynecologists, pediatricians and municipal staff members. The NHS program received the complete endorsement of the Akita Association of Obstetricians and Gynecologists in 2010. The largest increase in the NHS coverage rate occurred from 2001 to 2002, and the second largest increase occurred from 2009 to 2010. The number of participating institutions increased the coverage rate. The coverage rate is strongly correlated with the number of participating institutions (rs=0.843, p<0.001, Spearman's rank correlation coefficient). Comparing the coverage rate for 5 years before and after the Akita Association of Obstetricians and Gynecologists reached their consensus on the importance of NHS, the coverage rate after 2010 was significantly higher than before 2010 (p<0.001, paired sample t-test). CONCLUSION: The NHS coverage rate ultimately reached 95.4% without need for legislation or subsidization. The number of participating institutions increased each year, and the number of NHS tests and the coverage rate increased proportionately. The number of participating institutions statistically has a strong correlation with the number of NHS tests and the coverage rate. Our research indicates that the Akita leaflets and the provision of educational sessions about the importance of NHS were the most significant factors in establishing the high NHS coverage rate.

AB - Neprilysin is also known as skin fibroblast-derived elastase, and its up regulation during aging is associated with impairments of the elastic fiber network, loss of skin elasticity and wrinkle formation. However, information on its elastase activity is still limited. The aim of this study was to investigate the degradation of fibrillar skin elastin by neprilysin and the influence of the donor's age on the degradation process using mass spectrometry and bioinformatics approaches. The results showed that cleavage by neprilysin is dependent on previous damage of elastin. While neprilysin does not cleave young and intact skin elastin well, it degrades elastin fibers from older donors, which may further promote aging processes. With regards to the cleavage behavior of neprilysin, a strong preference for Gly at P1 was found, while Gly, Ala and Val were well accepted at P1' upon cleavage of tropoelastin and skin elastin. The results of the study indicate that the progressive release of bioactive elastin peptides by neprilysin upon skin aging may enhance local tissue damage and accelerate extracellular matrix aging processes.

PMID- 29196112 TI - Long-term outcomes and prognostic factors in patients with mild hemoptysis. AB - OBJECTIVE: The aim of this retrospective study was to observe the long-term outcomes of conservative treatment and bronchial artery embolization (BAE) in patients with mild hemoptysis and to analyze the risk factors associated with hemoptysis recurrence. METHODS: Patients with mild hemoptysis from January 2005 to January 2016 were enrolled in this study. The patients' medical records, including smoking history, etiologic diseases, bronchoscopic findings, mortality, BAE information, and follow-up data of recurrent hemoptysis, were reviewed and analyzed. RESULTS: A total of 288 patients with mild hemoptysis were included in this study. Of them, 71 patients (24.7%) underwent BAE and 217 patients (75.3%) were treated conservatively. The clinical success rate of BAE was 98.6%, with a low minor complication rate of 5.6%. Bronchoscopy before treatments was performed in 237 patients (82.3%). Fifty-five patients (19.1%) experienced recurrent hemoptysis during a median follow-up period of 2.4years (interquartile range: 1.0 4.4years). Patients who showed active bleeding or blood clots on bronchoscopy had a significantly lower recurrence-free survival rate than patients with no bronchoscopic evidence of bleeding or blood clots (p=0.012). The risk factors affecting recurrence were heavy smoking (p=0.002, hazard ratio [HR]: 3.57), aspergillosis (p=0.035, HR: 6.01), and bronchoscopic findings of active bleeding (p=0.016, HR: 3.29) or blood clots (p=0.012, HR: 2.77). CONCLUSIONS: The recurrence rate of hemoptysis was not negligible in patients with mild hemoptysis. BAE can be considered in patients with a high risk of recurrence.

PMID- 29196114 TI - Flexible, cluster-based analysis of the electronic medical record of sepsis with composite mixture models. AB - The widespread adoption of electronic medical records (EMRs) in healthcare has provided vast new amounts of data for statistical machine learning researchers in their efforts to model and predict patient health status, potentially enabling novel advances in treatment. In the case of sepsis, a debilitating, dysregulated host response to infection, extracting subtle, uncataloged clinical phenotypes from the EMR with statistical machine learning methods has the potential to impact patient diagnosis and treatment early in the course of their hospitalization. However, there are significant barriers that must be overcome to extract these insights from EMR data. First, EMR datasets consist of both static and dynamic observations of discrete and continuous-valued variables, many of which may be missing, precluding the application of standard multivariate analysis techniques. Second, clinical populations observed via EMRs and relevant to the study and management of conditions like sepsis are often heterogeneous; properly accounting for this heterogeneity is critical. Here, we describe an unsupervised, probabilistic framework called a composite mixture model that can simultaneously accommodate the wide variety of observations frequently observed in EMR datasets, characterize heterogeneous clinical populations, and handle missing observations. We demonstrate the efficacy of our approach on a large scale sepsis cohort, developing novel techniques built on our model-based clusters to track patient mortality risk over time and identify physiological trends and distinct subgroups of the dataset associated with elevated risk of mortality during hospitalization.

Although primarily known with painful oral and genital ulcers, it can lead to vasculitis. Therefore, several associated complications such as thrombotic syndromes, aneurysmal arterial disease may arise. In many cases, it might be difficult to make the diagnosis purely based on clinical grounds; however, imaging plays an important role for both diagnosis and assessment of the disease's complications. We provide a comprehensive review of the most notable imaging findings of Behcet's disease. PMID- 29196117 TI - Magnetic alginate microfibers as scaffolding elements for the fabrication of microvascular-like structures. AB - : Traditional cell-encapsulating scaffolds may elicit adverse host responses and inhomogeneity in cellular distribution. Thus, fabrication techniques for cellular self-assembly with micro-scaffold incorporation have been used recently to generate toroidal cellular modules for the bottom-up construction of vascular like structures. The micro-scaffolds show advantage in promoting tissue formation. However, owing to the lack of annular cell micro-scaffolds, it remains a challenge to engineer micro-scale toroidal cellular modules (micro-TCMs) to fabricate microvascular-like structures. Here, magnetic alginate microfibers (MAMs) are used as scaffolding elements, where a winding strategy enables them to be formed into micro-rings as annular cell micro-scaffolds. These micro-rings were investigated for NIH/3T3 fibroblast growth as a function of surface chemistry and MAM size. Afterwards, micro-TCMs were successfully fabricated with the formation of NIH/3T3 fibroblasts and extracellular matrix layers on the three dimensional micro-ring surfaces. Simple non-contact magnetic assembly was used to stack the micro-TCMs along a micro-pillar, after which cell fusion rapidly connected the assembled micro-TCMs into a microvascular-like structure. Endothelial cells or drugs encapsulated in the MAMs could be included in the microvascular-like structures as in vitro cellular models for vascular tissue engineering, or as miniaturization platforms for pharmaceutical drug testing in the future. STATEMENT OF SIGNIFICANCE: Magnetic alginate microfibers functioned as scaffolding elements for guiding cell growth in micro-scale toroidal cellular modules (micro-TCMs) and provided a magnetic functionality to the micro-TCMs for non-contact 3D assembly in external magnetic fields. By using the liquid/air interface, the non-contact spatial manipulation of the micro-TCMs in the liquid environment was performed with a cost-effective motorized electromagnetic needle. A new biofabrication paradigm of construct of microvascular-like structure. The micro-tubal-shaped structures allowed direct cell-to-cell contact that solved problems of cell-encapsulating scaffolds.

AB - : Cancer cell metastasis is responsible for approximately 90% of deaths related to cancer. The migration of cancer cells away from the primary tumor and into healthy tissue is driven in part by contact guidance, or directed migration in response to aligned extracellular matrix. While contact guidance has been a focus of many studies, much of this research has explored environments that present 2D contact guidance structures. Contact guidance environments in 3D more closely resemble in vivo conditions and model cell-ECM interactions better than 2D environments. While most cells engage in directed migration on potent 2D contact guidance cues, there is diversity in response to contact guidance cues based on whether the cell migrates with a mesenchymal or amoeboid migration mode. In this paper, rotational alignment of collagen gels was used to study the differences in contact guidance between MDA-MB-231 (mesenchymal) and MTLn3 (amoeboid) cells. MDA MB-231 cells migrate with high directional fidelity in aligned collagen gels, while MTLn3 cells show no directional migration. The collagen stiffness was increased through glycation, resulting in decreased MDA-MB-231 directionality in aligned collagen gels. Interestingly, partial inhibition of cell contractility dramatically decreased directionality in MDA-MB-231 cells. The directionality of MDA-MB-231 cells was most sensitive to ROCK inhibition, but unlike in 2D contact guidance environments, cell directionality and speed are more tightly coupled. Modulation of the contractile apparatus appears to more potently affect contact guidance than modulation of extracellular mechanical properties of the contact guidance cue. STATEMENT OF SIGNIFICANCE: Collagen fiber alignment in the tumor microenvironment directs migration, a process called contact guidance, enhancing the efficiency of cancer invasion and metastasis. 3D systems that assess contact guidance by locally orienting collagen fiber alignment are lacking. Furthermore, cell type differences and the role of extracellular matrix stiffness in tuning contact guidance fidelity are not well characterized. In this paper rotational alignment of collagen fibers is used as a 3D contact guidance cue to illuminate cell type differences and the role of extracellular matrix stiffness in guiding cell migration along aligned fibers of collagen. This local alignment offers a simple approach by which to couple collagen alignment with gradients in other directional cues in devices such as microfluidic chambers. PMID- 29196119 TI - Bone mineral density and markers of bone turnover and inflammation in diabetes patients with or without a Charcot foot: An 8.5-year prospective case-control study. AB - BACKGROUND AND AIMS: Charcot foot is a rare but severe complication to diabetes and peripheral neuropathy. It is still unclear if an acute Charcot foot has long term effects on the bone metabolism. To investigate this, we conducted a follow up study to examine if a previously acute Charcot foot has any long-term effects on bone mineral density (BMD) or local or systemic bone metabolism. METHODS: An 8.5-year follow-up case-control study of 44 individuals with diabetes mellitus, 24 of whom also had acute or chronic Charcot foot at the baseline visit in 2005 2007, who were followed up in 2015 with DXA scans and blood samples. RESULTS: 21 of the 44 baseline participants participated in the follow-up. There were no difference in the change in total hip BMD from baseline to follow-up in either the Charcot or the control group (p = 0.402 and 0.517), and no increased risk of osteoporosis in the previous Charcot feet either. From baseline to follow-up, there was a significant difference in the change in levels of fsRANK-L in the Charcot group, but not in the control group (p = 0.002 and 0.232, respectively). At follow-up, there were no differences in fsRANK-L between the groups. The fsRANK-L/OPG ratio also significantly decreased from baseline to follow-up in the Charcot group (3.4 versus 0.5) (p = 0.009), but not in the control group (1.3 versus 1.1) (p = 0.302). CONCLUSION: We found that diabetes patients with an acute Charcot foot have an elevated fsRANK-L/OPG ratio, and that the level decreased from baseline to follow-up to be comparable to the level in diabetes patients without previous or current Charcot foot. We found no permanent effect of an acute Charcot foot on hip or foot BMD. PMID- 29196120 TI - Severe hypoglycemia is a risk factor for atrial fibrillation in type 2 diabetes mellitus: Nationwide population-based cohort study. AB - AIMS: This study investigated the association between severe hypoglycemia (SH) and new onset atrial fibrillation (AF) and all-cause mortality in adult patients with type 2 diabetes mellitus (T2DM). METHODS: Retrospective data on patients with T2DM aged between 30 and 75years who received healthcare checkups from January 1, 2005 to December 31, 2008 were analyzed using the National Health Insurance Database in Korea. The primary outcome was newly diagnosed non-valvular AF occurring after SH episode using ICD-10 codes. RESULTS: Among 1,509,280 subjects, 10,864 (0.72%) patients had experienced SH events in the three years prior to health examination, and a total of 48,916 (3.24%) first-time AF episodes occurred during the follow-up period of 8.5years. The incidence of AF was significantly higher in the group with SH than the group without SH. After multivariable adjustment, previous SH was a significant risk factor for the development of AF (HR 1.10, 95% CI 1.01-1.19). All-cause mortality was also significantly increased in patients with previous SH events and prior SH with subsequent AF occurrence, compared to patients without SH events. CONCLUSIONS: Prior SH events were associated with a higher risk of new onset AF and all-cause mortality in patients with T2DM.

AB - Enterotoxigenic Escherichia coli (ETEC) is the main bacterial cause of dehydrating infant diarrhoea in less-developed countries. Labile toxin (LT) is the major virulent factor of ETEC. Easy diagnostic tests are necessary to reduce the number of cases. Immunological methods have some drawbacks and also have important limitations. For that reason, a Liquid Chromatography coupled to UV detector technique (LC-UV) has been optimize to a rapid identification and quantification of LT from bacteria cultures. It is also important to know optimal conditions for LT and with this purpose several enterotoxigenic E. coli strains have been studied to determine the influence of glucose concentration and different culture media on LT production. LC-UV technique demonstrated to be a good method for LT quantification showing values of 15 ng/mL and 45 ng/mL for limits of detection and quantification respectively. LT quantification revealed that toxin production is directly related to the concentration of glucose added in the broth medium. Tryptic Soy Broth is the most efficient culture medium for E. coli growth and enterotoxin production. PMID- 29196122 TI - Venoms of Centruroides and Tityus species from Panama and their main toxic fractions. AB - The scorpionism in Panama is notorious for the confluence and coexistence of buthid scorpions from the genera Centruroides and Tityus. This communication describes an overview of the larger representative toxic venom fractions from eight dangerous buthid scorpion species of Panama: Centruroides (C. granosus, C. bicolor, C. limbatus and C. panamensis) and Tityus (T. (A.) asthenes, T. (A.) festae, T. (T.) cerroazul and T. (A.) pachyurus). Their venoms were separated by HPLC and the corresponding sub-fractions were tested for lethality effects on mice and insects. Many fractions toxic to either mice or insects, or both, were found and have had their molecular masses determined by mass spectrometry analysis. The great majority of the lethal components had a molecular mass close to 7000 Da, assumed to be peptides that recognize Na+-channels, responsible for the toxicity symptoms observed in other buthids scorpion venoms. A toxic peptide isolated from the venom of T. pachyurus was sequenced by Edman degradation, allowing the synthesis of nucleotide probe for cloning the correspondent gene. The mature toxin based on the cDNA sequencing has the C-terminal residue amidated, contains 62 amino acid packed by 4 disulfide linkages, with molecular mass of 7099.1 Da. This same toxic peptide seems to be present in scorpions of the species T. pachyurus collected in 5 different regions of Panama, although the overall HPLC profile is quite different. The most diverse neurotoxic venom components from the genus Centruroides were found in the species C. panamensis, whereas T. cerroazul was the one from the genus Tityus. The most common neurotoxins were observed in the venoms of T. festae, T. asthenes and T. pachyurus with closely related molecular masses of 7099.1 and 7332 Da. The information reported here is considered very important for future generation of a neutralizing antivenom against scorpions from Panama. Furthermore, it will contribute to the growing interest in using bioactive toxins from scorpions for drug discovery purposes. PMID- 29196123 TI - Boosting 11-oxo-beta-amyrin and glycyrrhetinic acid synthesis in Saccharomyces cerevisiae via pairing novel oxidation and reduction system from legume plants. AB - Glycyrrhetinic acid (GA) and its precursor, 11-oxo-beta-amyrin, are typical triterpenoids found in the roots of licorice, a traditional Chinese medicinal herb that exhibits diverse functions and physiological effects. In this study, we developed a novel and highly efficient pathway for the synthesis of GA and 11-oxo beta-amyrin in Saccharomyces cerevisiae by introducing efficient cytochrome P450s (CYP450s: Uni25647 and CYP72A63) and pairing their reduction systems from legume plants through transcriptome and genome-wide screening and identification. By increasing the copy number of Uni25647 and pairing cytochrome P450 reductases (CPRs) from various plant sources, the titers of 11-oxo-beta-amyrin and GA were increased to 108.1 +/- 4.6mg/L and 18.9 +/- 2.0mg/L, which were nearly 1422-fold and 946.5-fold higher, respectively, compared with previously reported data. To the best of our knowledge, these are the highest titers reported for GA and 11 oxo-beta-amyrin from S. cerevisiae, indicating an encouraging and promising approach for obtaining increased GA and its related triterpenoids without destroying the licorice plant or the soil ecosystem. PMID- 29196124 TI - Combined engineering of disaccharide transport and phosphorolysis for enhanced ATP yield from sucrose fermentation in Saccharomyces cerevisiae. AB - Anaerobic industrial fermentation processes do not require aeration and intensive mixing and the accompanying cost savings are beneficial for production of chemicals and fuels. However, the free-energy conservation of fermentative pathways is often insufficient for the production and export of the desired compounds and/or for cellular growth and maintenance. To increase free-energy conservation during fermentation of the industrially relevant disaccharide sucrose by Saccharomyces cerevisiae, we first replaced the native yeast alpha glucosidases by an intracellular sucrose phosphorylase from Leuconostoc mesenteroides (LmSPase). Subsequently, we replaced the native proton-coupled sucrose uptake system by a putative sucrose facilitator from Phaseolus vulgaris (PvSUF1). The resulting strains grew anaerobically on sucrose at specific growth rates of 0.09 +/- 0.02h-1 (LmSPase) and 0.06 +/- 0.01h-1 (PvSUF1, LmSPase). Overexpression of the yeast PGM2 gene, which encodes phosphoglucomutase, increased anaerobic growth rates on sucrose of these strains to 0.23 +/- 0.01h-1 and 0.08 +/- 0.00h-1, respectively. Determination of the biomass yield in anaerobic sucrose-limited chemostat cultures was used to assess the free-energy conservation of the engineered strains. Replacement of intracellular hydrolase with a phosphorylase increased the biomass yield on sucrose by 31%. Additional replacement of the native proton-coupled sucrose uptake system by PvSUF1 increased the anaerobic biomass yield by a further 8%, resulting in an overall increase of 41%. By experimentally demonstrating an energetic benefit of the combined engineering of disaccharide uptake and cleavage, this study represents a first step towards anaerobic production of compounds whose metabolic pathways currently do not conserve sufficient free-energy. PMID- 29196125 TI - Prescription patterns and costs of antidiabetic medications in a large group of patients. AB - AIMS: To determine the prescription patterns of antidiabetic medications and the variables associated with their use in a Colombian population. METHODS: A cross sectional study using a systematized database of approximately 3.5 million affiliates of the Colombian Health System. Patients of both genders and all ages treated uninterruptedly with antidiabetic medications for three months (June August 2015) were included. A database was designed that included sociodemographic, pharmacological, comedication, and cost variables. RESULTS: A total of 47,532 patients were identified; the mean age was 65.5 years, and 56.3% were women. Among the patients, 56.2% (n=26,691) received medication as monotherapy. The most prescribed medications were metformin, 81.3% (n=38,664), insulins, 33.3% (n=15,848), and sulfonylureas, 21.8% (n=10,370). Among the patients, 92.8% received comedications, including antihypertensives (79.7%), hypolipemiants (65.5%), antiplatelet drugs (56.3%), analgesics (33.9%), antiulcerants (33.1%), and thyroid hormone (17.3%). The cost per 1000 inhabitants/day was $1.21 USD for metformin, $3.89 USD for insulins, and $0.02 USD for glibenclamide. CONCLUSIONS: Generally, rational prescription habits predominated, however in some cases an overuse of comedications (such as antiulcer drugs) and a large group of patients with high cost formulations were observed. Subsequent effectiveness and cost-benefit analyzes are required. PMID- 29196127 TI - LncRNAs and CircRNAs from the same gene: Masterpieces of RNA splicing. AB - Accumulating evidence has shown that lncRNAs and circRNAs are novel regulators of gene expression. The discovery of numerous lncRNAs and circRNAs, and investigation into their structures and functions will contribute to our understanding of the pathogenesis of diseases as well as better prevention, diagnosis, and treatment of diseases. There is a close relationship between circRNAs and lncRNAs regarding their origins and functions. Recent studies have shown that non-coding linear and circular transcripts can be transcribed from the same gene and are potential super-enhancers modulating gene transcription. In this review, we summarize the categories, characteristics, biological functions and databases of both lncRNAs and circRNAs, focusing on their transcriptions derived from the same gene, which might give us a deeper understanding of and enable us to better recognize and distinguish their physiological roles. PMID- 29196128 TI - Maintenance of stemness by miR-589-5p in hepatocellular carcinoma cells promotes chemoresistance via STAT3 signaling. AB - The strength and duration of STAT3 signaling are tightly controlled by multiple negative feedback mechanisms under physical conditions. However, how these serial feedback loops are simultaneously disrupted in cancers, leading to constitutive activation of STAT3 signaling in hepatocellular carcinoma (HCC), remains obscure. Here we report that miR-589-5p is elevated in HCC tissues, which is caused by recurrent gains. Overexpression of miR-589-5p correlates with poor overall and relapse-free survival in HCC patients. Upregulating miR-589-5p enhances spheroid formation ability, fraction of CD133 positive and side population cells, expression of cancer stem cell factors and the mitochondrial potential, and represses the apoptosis induced by doxorubicin in vitro and tumorigenicity in vivo in HCC cells; conversely, silencing miR-589-5p yields an opposite effect. Our findings further demonstrate miR-589-5p promotes the cancer stem cell characteristics and chemoresistance via targeting multiple negative regulators of STAT3 signaling pathway, including SOCS2, SOCS5, PTPN1 and PTPN11, leading to constitutive activation of STAT3 signaling. Collectively, our results unravel a novel mechanism by which miR-589-5p promotes the maintenance of stemness and chemoresistance in HCC, providing a potential rational registry of anti-miR-589 5p combining with conventional chemotherapy against HCC. PMID- 29196126 TI - Oncogenic Kit signalling on the Golgi is suppressed by blocking secretory trafficking with M-COPA in gastrointestinal stromal tumours. AB - Most gastrointestinal stromal tumours (GISTs) are caused by constitutively active mutations in Kit tyrosine kinase. The drug imatinib, a specific Kit inhibitor, improves the prognosis of metastatic GIST patients, but these patients become resistant to the drug by acquiring secondary mutations in the Kit kinase domain. We recently reported that a Kit mutant causes oncogenic signals only on the Golgi apparatus in GISTs. In this study, we show that in GIST, 2-methylcoprophilinamide (M-COPA, also known as "AMF-26"), an inhibitor of biosynthetic protein trafficking from the endoplasmic reticulum (ER) to the Golgi, suppresses Kit autophosphorylation at Y703/Y721/Y730/Y936, resulting in blockade of oncogenic signalling. Results of our M-COPA treatment assay show that Kit Y703/Y730/Y936 in the ER are dephosphorylated by protein tyrosine phosphatases (PTPs), thus the ER retained Kit is unable to activate downstream molecules. ER-localized Kit Y721 is not phosphorylated, but not due to PTPs. Importantly, M-COPA can inhibit the activation of the Kit kinase domain mutant, resulting in suppression of imatinib resistant GIST proliferation. Our study demonstrates that Kit autophosphorylation is spatio-temporally regulated and may offer a new strategy for treating imatinib resistant GISTs. PMID- 29196129 TI - Stanniocalcin-1 augments stem-like traits of glioblastoma cells through binding and activating NOTCH1. AB - Glioblastoma (GBM) is a fatal tumor and comprises heterogeneous cells in which a subpopulation with stem cell-like properties is included. Cancer cells with stem cell-like properties account for tumor initiation, drug resistance and recurrence. To identify and characterize specific factors in regulating stem-like traits is critical for GBM therapeutic. Here, we showed that Stanniocalcin-1 (STC1), a secretory glycoprotein, functions as a novel stimulator for stem-like traits of GBM cells. We found STC1 was prominently expressed in glioma spheres which are mainly comprised of glioma stem-like cells. The stem-like traits of GBM cells, as determined by the expression of stem cell markers, tumor-sphere formation efficiency and colony-forming ability, were enhanced by STC1 overexpression and inhibited by STC1 knockdown. Furthermore, introduction of STC1 enhanced tumorigenesis in vivo while knockdown of STC1 showed reverse effect. Finally, we demonstrated that STC1 interacted with the extracellular domain of NOTCH1 to activate NOTCH1-SOX2 signaling pathway, by which STC1 augmented the stem-like traits of GBM cells. Taken together, our data herein indicate that STC1 is a novel non-canonical NOTCH ligand and acts as a crucial regulator of stemness in GBM.

In China, although there have been a few reports on Blastocystis infection in humans and many animal species, no epidemiological data are available in either humans or animals in northeastern China's Heilongjiang Province. To determine infection rates and subtype distributions of Blastocystis in pigs, cattle, sheep and goats, to understand genetic characterizations and to assess zoonotic possibility of Blastocystis isolates, 337 fecal specimens from livestock (68 from pigs, 147 from cattle, 109 from sheep and 13 from goats) were collected in northeastern China's Heilongjiang Province. Each of them was detected for Blastocystis by PCR amplification of the partial SSU rRNA gene. An average infection rate of Blastocystis was 7.7% (26/337), and the highest infection rate was found in 9.5% (14/147) in cattle, followed by 8.8% (6/68) in pigs and 5.5% (6/109) in sheep. There was an absence of Blastocystis in goats. Five Blastocystis subtypes were identified: ST5 (n=6) in pigs; ST3 (n=2), ST10 (n=10) and ST14 (n=2) in cattle; ST1 (n=1), ST5 (n=1), ST10 (n=3) and ST14 (n=1) in sheep. 38.5% (10/26) of Blastocystis isolates belong to potentially zoonotic subtypes based on the previous findings of ST1, ST3 and ST5 in humans. This is the first report of Blastocystis in pigs, cattle and sheep in northeastern China's Heilongjiang Province. ST1, ST5 and ST14 were identified in sheep for the first time. Due to the low infection rate of Blastocystis and the small percentage of potentially zoonotic subtypes in these livestock, there is a minimal risk of zoonotic transmission of Blastocystis.

AB - OBJECTIVE: Adipokines have been reported to play a role in the development, progression and severity of knee osteoarthritis but the influence of the different adipokines are not well known. The aim of this study was to evaluate the association between different synovial fluid adipokines with pain and disability knee osteoarthritis patients. METHODS: Cross-sectional study with systematic inclusion of 115 symptomatic primary knee osteoarthritis female patients with ultrasound-confirmed joint effusion. Age, physical exercise, symptoms duration and different anthropometric measurements were collected. Radiographic severity was evaluated according to Kellgren-Lawrence scale. Pain and disability were assessed by WOMAC-total, -pain, -function subscales and Knee injury and Osteoarthritis Outcome Score (KOOS) pain and function scales. Seven adipokines and three inflammatory markers were measured by ELISA in synovial fluid. Partial Correlation Coefficient (PCC) and corresponding 95% confidence interval were used as a measure of association. RESULTS: Leptin, osteopontin and inflammatory factors, especially TNF-alpha, were associated to pain and function. After adjustment for potential confounders including inflammatory factors and all adipokines, an association was found for adiponectin with pain (PCC 0.240 [0.012, 0.444]) and for resistin and visfatin with function (PCC 0.336 [0.117, 0.524] and -0.262 [-0.463, -0.036]). No other adipokines or inflammatory markers were statistically and independently associated. An association between physical exercise and pain and disability remained after adjustment, whereas an attenuation of the influence of anthropometric measurements was observed. CONCLUSIONS: Different patterns of association between synovial fluid adipokines were observed regarding pain and disability in knee osteoarthritis patients. Specifically, adiponectin was associated to pain while resistin and visfatin were mainly related to function. PMID- 29196132 TI - Association of TNF-alpha (-308 A/G) and IFN-gamma (+874 A/T) gene polymorphisms in response to spontaneous and treatment induced viral clearance in HCV infected multitransfused thalassemic patients. AB - BACKGROUND: Multitransfused thalassemic individuals are at high risk of developing transfusion transmitted Hepatitis C virus (HCV) infection. The aim of the study was to correlate the effects of host cytokine single nucleotide polymorphisms of TNF-alpha (-308 A/G) and IFN-gamma (+874 A/T) in spontaneous or IFN induced treatment response in the HCV infected thalassemic individuals. METHODS: A total of 427 HCV sero-reactive thalassemic individuals were processed for HCV viral genomic diversity and host gene polymorphisms analysis of TNF-alpha (-308 A/G) and IFN-gamma (+874 A/T). RESULTS: Out of 427 HCV sero-reactive individuals, 69.09% were found to be HCV RNA positive with genotype 3 as the predominant infecting strain (94.29%). Study highlighted that, A allele was significantly associated with (p < .05) spontaneous clearance of HCV infection and G allele was correlated with viral persistence at TNF-alpha (-308) gene polymorphism. Whereas in case of IFN-gamma (+874) SNPs, A allele was significantly responsible (p < .05) for spontaneous clearance than T allele. Our study also indicated that in relapsed cases, IFN-gamma (+874) T allele is more responsible than A allele. Though no significant correlation was found at both TNF-alpha (-308) and IFN-gamma (+874) gene polymorphism among SVR and relapsed thalassemic patients. CONCLUSION: A allele at both TNF-alpha (-308) and IFN-gamma (+874) were strongly associated with spontaneous clearance among this population. But in case of SVR and relapsed cases no significant association was found. This cytokine gene polymorphisms pattern will help clinicians to take an informed decision about therapeutic management of HCV infected thalassemic individuals. PMID- 29196133 TI - Rapid negative inotropic effect induced by TNF-alpha in rat heart perfused related to PKC activation. AB - Myocardial depression, frequently observed in septic shock, is mediated by circulating molecules such as cytokines. TNF-alpha appears to be the most important pro-inflammatory cytokine released during the early phase of a septic shock. It was previously shown that TNF-alpha had a negative inotropic effect on myocardium. Now, the aim of this study was to investigate the effects of the activation of PKC by TNF-alpha on heart function, and to determine if this cytokine could induce a decrease of membrane excitability. Isolated rat hearts (n = 6) were perfused with Tyrode solution containing TNF-alpha at 20 ng/ml during 30 min by using a Langendorff technique. Expressions of PKC-alpha and PKC-epsilon were analysed by western blot on membrane and cytosol proteins extracted from ventricular myocardium. Patch clamp was performed on freshly isolated cardiomyocytes (n = 8). Compared to control situation, 30 min of TNF-alpha perfusion led to cardiac dysfunction with a decrease of the heart rate (-83%), the force (-20%) and speed of relaxation (-18%) and the coronary flow (-25%). This is associated with an activation and a membrane targeting of both PKC-alpha and PKC-epsilon isoforms in ventricle with respectively +123% and +54% compared to control hearts. Nevertheless, TNF-alpha had no significant effect on voltage gated sodium current (109.0%+/- 12.5) after addition of the cytokine when compared to control. These results showed that TNF-alpha had a negative inotropic effect on the isolated rat heart and can induce PKC activation leading to an impaired contractility of the heart. However the early heart dysfunction induced by the cytokine was not associated to a decrease of cardiomyocytes membrane excitability as it has been evidenced in skeletal muscle fibres.

AB - ETHNOPHARMACOLOGICAL RELEVANCE: Salvadora persica L., also known as Arak (in Arabic) and Peelu (in Urdu), is the most common traditional source of tooth or chewing stick (miswak) highly recommended by Prophet Muhammad. To date, extensive studies have probed primarily into the validation of its traditional uses in oral care. Nonetheless, there is still a dearth of updated compilation and critical analysis of other potential ethnopharmacological properties of S. persica. This review therefore aims to provide an up-to-date detailed structured description of the traditional uses of S. persica and a critical analysis of its modern uses, highlighting its phytochemistry, pharmacological properties, and bioapplications. MATERIALS AND METHODS: Various databases (Science Direct, PubMed, Wiley Online Library, and Google Scholar), books, and relevant primary sources were probed, surveyed, analysed, and included in this review. The literature cited in this review dated from 1979 to 2017. RESULTS: S. persica was found to possess a plethora of bioactive compounds and broad pharmacological properties, including antimicrobial, antioxidant, enzyme inhibitory activity, antiulcer, anticonvulsant, sedative, analgesic, anti-inflammatory, hypoglycemic, hypolipidemic, antiosteoporosis, and antitumor activities. Studies also revealed the potential use of S. persica as a natural food preservative and a novel functional food ingredient. In addition, improvement in growth and reproductive performances have been observed by the introduction of S. persica in animal feed. Lastly, S. persica has also been used in the green synthesis of nanoparticles showing potential biotechnological applications. CONCLUSION: S. persica showed a wide scope of application and its uses have been extended far beyond the initial traditional uses of its roots, stems, and twigs in oral care. We found a number of other ethnopharmacological uses and potential bioapplications of different parts of S. persica that warrants further investigations. Though widely studied using several in vitro and in vivo models, and tested clinically for oral hygiene mainly, several gaps and research priorities have been identified which needs to be addressed in future.

AB - Decreased HDL cholesterol (HDL-c) is considered as an independent risk factor of cardiovascular disease in metabolic syndrome (Mets). Wendan decoction (WDD), a famous clinical traditional Chinese medicine formula in Mets in China, which can obviously up-regulate serum HDL-c levels in Mets. However, till now, the molecular mechanism of up-regulation still remained unclear. In this study, an integrated approach that combined serum ABCA1 in vivo assay, QSAR modeling and molecular docking was developed to explore the molecular mechanism and chemical substance basis of WDD upregulating HDL-c levels. Compared with Mets model group, serum ABCA1 and HDL-c levels intervened by two different doses of WDD for two weeks were significantly up-regulated. Then, kohonen and LDA were applied to develop QSAR models for ABCA1 up-regulators based flavonoids. The derived QSAR model produced the overall accuracy of 100%, a very powerful tool for screening ABCA1 up-regulators. The QSAR model prediction revealed 67 flavonoids in WDD were ABCA1 up-regulators. Finally, they were subjected to the molecular docking to understand their roles in up-regulating ABCA1 expression, which led to discovery of 23 ABCA1 up-regulators targeting LXR beta. Overall, QSAR modeling and docking studies well accounted for the observed in vivo activities of ABCA1 affected by WDD.

PMID- 29196141 TI - Effect of resistance training on muscle strength and rate of force development in healthy older adults: A systematic review and meta-analysis. AB - Rapid force capacity, identified by rate of rise in contractile force at the onset of contraction, i.e., the rate of force development (RFD), has been considered an important neuromuscular parameter of physical fitness in elderly individuals. Randomized control studies conducted in adults have found that resistance training may elicit different outcomes in terms of RFD and muscle strength. Thus, the main purpose of this study was to review systematically the literature for studies regarding the influence of resistance training on muscle strength and RFD in elderly persons. A literature search was performed in major electronic databases from inception to March 2017. Studies including health individuals with a mean age>=60years, describing the effect of resistance training on RFD and muscle strength were found eligible. The outcomes were calculated as the difference in percentage change between control and experimental groups (% change) and data were presented as mean+/-95% confidence limits. Meta-analyses were performed using a random-effects model and, in addition, simple and multiple meta-regression analyses were used to identify effects of age, training type, sessions per week and training duration on % change in RFD and muscle strength. Thirteen training effects were collected from 10 studies included in the meta-analysis. The resistance training program had a moderate beneficial effect on both muscle strength (% change=18.40%, 95% CL 13.69 23.30, p<0.001) and RFD (% change=26.68, 95% CL 14.41-35.52, p<0.001). Results of the meta-regression revealed that the variables age, training type (i.e., strength and explosive), training duration (4-16weeks) and sessions per week had no significant effects on muscle strength and RFD improvement. Moreover, there was no significant relationship (p=0.073) between the changes in muscle strength and RFD. It can be concluded that explosive training and heavy strength training are effective resistance training methods aiming to improve both muscle strength and RFD after short-to-medium training period. However, muscle strength and RFD seem to adapt differently to resistance training programs, suggesting caution for their interchangeable use in clinical assessments of the elderly. PMID- 29196142 TI - New transgenic models of Parkinson's disease using genome editing technology. AB - INTRODUCTION: Parkinson's disease (PD) is the second most common neurodegenerative disorder. It is characterised by selective loss of dopaminergic neurons in the substantia nigra pars compacta, which results in dopamine depletion, leading to a number of motor and non-motor symptoms. DEVELOPMENT: In recent years, the development of new animal models using nuclease-based genome editing technology (ZFN, TALEN, and CRISPR/Cas9 nucleases) has enabled the introduction of custom-made modifications into the genome to replicate key features of PD, leading to significant advances in our understanding of the pathophysiology of the disease. CONCLUSIONS: We review the most recent studies on this new generation of in vitro and in vivo PD models, which replicate the most relevant symptoms of the disease and enable better understanding of the aetiology and mechanisms of PD. This may be helpful in the future development of effective treatments to halt or slow disease progression. PMID- 29196143 TI - Intravenous immunoglobulin G as adjuvant treatment in drug-resistant childhood epilepsy. AB - BACKGROUND: Epilepsy is the most common neurological disease in childhood; depending on the definition of drug-resistant epilepsy, incidence varies from 10% to 23% in the paediatric population. The objective of this study was to account for the decrease in the frequency and/or monthly duration of epileptic seizures in paediatric patients with drug-resistant epilepsy treated with antiepileptic drugs, before and after adding intravenous immunoglobulin G (iIV IgG). METHODS: This is an analytic, observational, retrospective case-control study. We studied paediatric patients with drug-resistant epilepsy who were treated with IV IgG at the Centro Medico Nacional 20 de Noviembre, in Mexico City, from 2003 to 2013. RESULTS: One hundred and sixty seven patients (19.5%) had drug-resistant epilepsy and 44 (5.1%) started adjuvant treatment with IV IgG. The mean age of patients at the beginning of treatment was 6.12 years+/-5.14); aetiology was structural acquired in 28 patients (73.6%), genetic in 5 (13.1%), immune in 1 (2.6%), and unknown in 4 (10.5%). At 2 months from starting IV IgG, seizure duration had reduced to 66.66%; the frequency of seizures was reduced by 64% at 4 months after starting treatment (P<.001). CONCLUSIONS: According to the results of this study, intravenous immunoglobulin may be an effective therapy for reducing the frequency and duration of seizures in paediatric patients with drug-resistant epilepsy. PMID- 29196144 TI - Spatio-temporal expression of Hexokinase-3 in the injured female rat spinal cords. AB - Hexokinase-3 (HK3) is a member of hexokinase family, which can catalyze the first step of glucose metabolism. It can increase ATP levels, reduce the production of reactive oxygen species, increase mitochondrial biogenesis, protect mitochondrial membrane potential and play an antioxidant role. However, the change of its expression in spinal cord after injury is still unknown. In this study, we investigated the spatio-temporal expression of HK3 in the spinal cords by using a spinal cord injury (SCI) model in adult female Sprague-Dawley rats. Quantitative reverse transcription-PCR and western blot analysis revealed that HK3 could be detected in sham-opened spinal cords. After SCI, it gradually increased, reached a peak at 7 days post-injury (dpi), and then gradually decreased with the prolonging of injury time, but still maintained at a higher level for up to 28 dpi (the longest time evaluated in this study). Immunofluorescence staining showed that HK3 was found in GFAP+, beta-tubulin III+ and IBA-1+ cells in sham opened spinal cords. After SCI, in addition to the above-mentioned cells, it could also be found in CD45+ and CD68+ cells. These results demonstrate that HK3 is mainly expressed in astrocytes, neurons and microglia in normal spinal cords, and could rapidly increase in infiltrated leukocytes, activated microglia/macrophages and astrocytes after SCI. These data suggest that HK3 may be involved in the pathologic process of SCI by promoting glucose metabolism. PMID- 29196145 TI - Effects of imipramine on cytokines panel in the rats serum during the drug treatment and discontinuation. AB - Time dependent sensitization (TDS) - phenomenon described originally by Chiodo and Antelman (1980) in context of dopamine receptors, refers to cascade of events that continue to develop in the organism, after the initiating stimulus is no longer available. Treatment could be recognized as such a initiating stimulus (in case of depression, example of electroconvulsive therapy would be obvious, but some aspects of pharmacotherapy too). The process leads to improvement, but, on the other hand, phenomena of kindling in recurrent depression is well known (more relapses and therapies make heavier and longer lasting subsequent episodes). Hence our interest in delayed effects of treatment. Here we report alterations in rat immune system after Imipramine (IMI) treatment cessation. Wistar male rats were treated with IMI (10 mg/kg i.p. in 2 ml/kg of saline) repeatedly for 21 days or once - on the last day of drug administration period. Then the 3 weeks discontinuation phase begun, during which, at certain time points (3 h, 72 h, 7days, 21days) the trunk blood was collected. Tissue concentrations of IMI and its metabolite desipramine (DMI), as well as ACTH and various cytokines were measured. The IMI and DMI was detectable only 3 h after the last i.p. injection of the drug. Ever since the second time point (72 h of discontinuation) the levels of either compound were below detection threshold.There was no significant changes in ACTH levels between rat groups, although IMI seemed to attenuate alterations of the hormone level comparing to control groups. We observed differences between groups regarding certain cytokines at certain time points. Namely: at 72 h of discontinuation IL-2 and IL-4 were elevated in sera of rats treated with IMI acutely; at 7d of discontinuation levels of IL-1alpha, IL-5, IL 10 and IL-12 were affected in both acutely and chronically treated animals. Presented data support, regarding some cytokines in serum, the TDS theory. Furthermore they refer to important aspect of antidepressants (ADs) action - antidepressant discontinuation syndrome (ADS). The most frequently, ADS has been described in context of ADs-disrupted monoamine homeostasis. Here, the other principle (i.e. immunomodulation) of the syndrome is proposed. PMID- 29196146 TI - A non-synaptic mechanism of complex learning: Modulation of intrinsic neuronal excitability. AB - Training rats in a particularly difficult olfactory discrimination task initiates a period of accelerated learning of other odors, manifested as a dramatic increase in the rats' capacity to acquire memories for new odors once they have learned the first discrimination task, implying that rule learning has taken place. At the cellular level, pyramidal neurons in the piriform cortex, hippocampus and bsolateral amygdala of olfactory-discrimination trained rats show enhanced intrinsic neuronal excitability that lasts for several days after rule learning. Such enhanced intrinsic excitability is mediated by long-term reduction in the post-burst after-hyperpolarization (AHP) which is generated by repetitive spike firing, and is maintained by persistent activation of key second messenger systems. Much like late-LTP, the induction of long-term modulation of intrinsic excitability is protein synthesis dependent. Learning-induced modulation of intrinsic excitability can be bi-directional, pending of the valance of the outcome of the learned task. In this review we describe the physiological and molecular mechanisms underlying the rule learning-induced long-term enhancement in neuronal excitability and discuss the functional significance of such a wide spread modulation of the neurons' ability to sustain repetitive spike generation. PMID- 29196147 TI - Mast Cells as Drivers of Disease and Therapeutic Targets. AB - Mast cells (MCs) contribute to the pathogenesis of a multitude of diseases that include MC-driven disorders such as urticaria, type I allergies, and mastocytosis as well as autoimmune and other inflammatory disorders and malignant tumors. Here, we review and discuss the results of studies that identified and characterized how MCs contribute to disease and, importantly, what strategies may be used to target MCs and MC effects therapeutically. Specifically, we discuss the most common approaches for investigating the role and relevance of MCs in various diseases. We also review current therapeutic approaches aimed at modulating MC numbers, inhibiting MCs and/or preventing MC activation, modulating MC signal transduction and protection from the effects of MC mediators. PMID- 29196148 TI - Circulating IL-17-producing mucosal-associated invariant T cells (MAIT) are associated with symptoms in children with asthma. AB - IL-17 and mucosal-associated invariant T (MAIT) cells have been involved in asthma pathogenesis. However, IL-17-producing MAIT cells (MAIT-17) were not evidenced. We aimed to determine whether circulating MAIT-17 were detectable in children with asthma, and whether they correlated with asthma symptoms or lung function. Children from the SPASM cohort of preschoolers with severe wheeze were reassessed for asthma at school age, and categorized as exacerbators (1 or more severe exacerbations in the previous 12months) or non-exacerbators. Nineteen children (10.9years) were included (9 non-exacerbators, 10 exacerbators). Circulating MAIT-17 were detected by flow cytometry. Their frequency was higher in exacerbators than in non-exacerbators (1.9 [1.01-3.55] vs 0.58 [0.46-1.15], p<0.01). MAIT-17 correlated with the number of severe exacerbations (r=0.68, p<0.001), and correlated negatively with the ACT score (r=-0.55, p=0.01). In summary, MAIT-17 are present in children with asthma and associated with asthma symptoms. PMID- 29196149 TI - Continuous positive airway pressure treatment with nasal pillows in obstructive sleep apnea: long-term effectiveness and adherence. AB - BACKGROUNDS: Mask-related side effects can negatively influence adherence to continuous positive airway pressure (CPAP). Nasal pillows (P) can be an alternative to the standard nasal masks (N), although there are no data about their long-term efficacy. This study aimed to assess long-term effectiveness and adherence to CPAP therapy delivered with nasal pillows in obstructive sleep apnea syndrome (OSAS) patients. METHODS: A retrospective observational design involving a series of consecutive CPAP-naive patients affected by OSAS. After an initial mask fitting session all patients were allowed to choose the type of nasal interface (N or P) they preferred. Outcomes were assessed 5 days after CPAP titration, and after 2 and 12 months. Patients were offered the option of switching to an alternative mask if needed. RESULTS: Data from 144 patients were analyzed. Subjects were predominantly male (76%), middle aged (58.14 +/- 12.86), moderately obese (body mass index: 33.89 +/- 7.56), and affected by severe OSAS (apnea-hypopnea index: 47.60 +/- 21.31). A total of 102 patients (70.8%) chose P, and 42 (29.2%) chose N. Clinical and polygraphic features, and CPAP pressure levels were similar in P and N groups, both at baseline and at 12 months. A good adherence to treatment was observed in both groups (P, 5.5 +/- 1.8 h; N, 5.3 +/- 1.5 h). Seventy-six patients (53%) reported at least one side effect during the whole study period, without statistically significant between-group differences. Nostril pain was the most frequent side effect in P. CONCLUSIONS: Nasal pillows showed equal long-term effectiveness and objective adherence as standard nasal masks. PMID- 29196150 TI - SGLT2 inhibitors with cardiovascular benefits: Transforming clinical care in Type 2 diabetes mellitus. AB - Cardiovascular risk reduction in individuals with Type 2 diabetes mellitus (T2DM) is a key part of clinical management. Sodium-glucose co-transporter (SGLT2) inhibitors improve glycaemic control, reduce body weight and decrease blood pressure. In addition, the SGLT2 inhibitors empagliflozin and canagliflozin reduced the risk of composite cardiovascular events in high-risk individuals with T2DM in the EMPA-REG OUTCOME trial and the CANVAS Program, respectively. Empagliflozin also reduced cardiovascular deaths and improved renal outcomes. This class of agents should be considered in people with established cardiovascular disease, usually in combination with other glucose lowering medications, when satisfactory glycaemic control has not been achieved. The dose of insulin or sulfonylureas may need to be lowered when used with SGLT2 inhibitors, to reduce the risk of hypoglycaemia. Genitourinary infections can occur with SGLT2 inhibitors in a small proportion of people. In people with osteoporosis or prior amputation, it may be prudent to use empagliflozin rather than canagliflozin, based on the increased risk for bone fractures and amputations observed with canagliflozin in the CANVAS Program. SGLT2 inhibitors have the potential to transform the clinical care of persons with T2DM by not only improving glycaemic control but also reducing blood pressure, body weight and diabetes-related end-organ complications. PMID- 29196151 TI - Effect of vitamin K2 on type 2 diabetes mellitus: A review. AB - Type 2 diabetes mellitus (T2DM) continue to be a major public health problem around the world that frequently presents with microvascular and macrovascular complications. Individuals with T2DM are not only suffering from significant emotional and physical misery, but also at increased risk of dying from severe complications. In recent years, evidence from prospective observational studies and clinical trials has shown T2DM risk reduction with vitamin K2 supplementation. We thus did an overview of currently available studies to assess the effect of vitamin K2 supplementation on insulin sensitivity, glycaemic control and reviewed the underlying mechanisms. We proposed that vitamin K2 improved insulin sensitivity through involvement of vitamin K-dependent-protein osteocalcin, anti-inflammatory properties, and lipid-lowering effects. Vitamin K2 had a better effect than vitamin K1 on T2DM. The interpretation of this review will increase comprehension of the development of a therapeutic strategy to prevent and treat T2DM. PMID- 29196152 TI - Nanotechnology based approaches for anti-diabetic drugs delivery. AB - Nanotechnology science has been diverged its application in several fields with the advantages to operate with nanometric range of objects. Emerging field of nanotechnology has been also being approached and applied in medical biology for improved efficacy and safety. Increased success in therapeutic field has focused several approaches in the treatment of the common metabolic disorder, diabetes. The development of nanocarriers for improved delivery of different oral hypoglycemic agents compared to conventional therapies includes nanoparticles (NPs), liposomes, dendrimer, niosomes and micelles, which produces great control over the increased blood glucose level and thus becoming an eye catching and most promising technology now-a-days. Besides, embellishment of nanocarriers with several ligands makes it more targeted delivery with the protection of entrapped hypoglycaemic agents against degradation, thereby optimizing prolonged blood glucose lowering effect. Thus, nanocarriers of hypoglycemic agents provide the aim towards improved diabetes management with minimized risk of acute and chronic complications. In this review, we provide an overview on distinctive features of each nano-based drug delivery system for diabetic treatment and current NPs applications in diabetes management. PMID- 29196153 TI - Efficacy and safety of vaginally administered lyophilized Lactobacillus crispatus IP 174178 in the prevention of bacterial vaginosis recurrence. AB - BACKGROUND: Bacterial vaginosis (BV) is a recurrent disease in women despite treatment by antibiotics. This study investigated the impact of a vaginal probiotic, Lactobacillus crispatus IP174178* (Lc), on the rate of recurrence and time to recurrence. METHODS: A prospective, multi-centre, double blind, randomised phase III trial in women with at least two documented episodes of BV in the previous year (diagnosis confirmed by presence of three Amsel criteria and a Nugent score>=7), and who had been clinically cured (i.e., no Amsel criteria) after oral metronidazole treatment (1g/day*7 days). The patients were randomised to receive vaginal capsules of either Lc or placebo, once a day, for 14 days over the first two menstrual cycles and another 14 days of the same treatment for the following two menstrual cycles. The primary efficacy endpoint was the number of patients with at least one bacteriologically confirmed recurrence of BV. RESULTS: Out of 98 assessable patients (mean age 35.7 years), 78 women were evaluated (20 patients had missing data). During the treatment period, 16/39 patients (41%) had at least one recurrence in the placebo group versus 8/39 patients (20.5%) in the Lc group (P=0.0497). The time to recurrence was longer by 28% in the Lc group (3.75+/-0.16 months) vs. the placebo group (2.93+/-0.18 months) (P=0.0298). Tolerability and safety were good in both groups. CONCLUSION: In women with recurrent BV after antibiotics, treatment with Lc IP 174178 administered over four menstrual cycles, could significantly reduce the rate of recurrence and increase the time to recurrence. PMID- 29196154 TI - Labour induction practices in France: A population-based declarative survey in 94 maternity units. AB - INTRODUCTION: In 2016, 22.0% of deliveries in France were induced. The current lack of high level of evidence data about the methods and indications for induction of labour has promoted heterogeneous and non-recommended practices. The extent of these different practices is not adequately known in France today, although they may influence perinatal outcomes. The objective of this study was to report current practices of induction of labour in France. MATERIAL AND METHODS: This study surveyed 94 maternity units in seven perinatal networks. A questionnaire was sent by email to either the department head or delivery room supervisor of these units to ask about their methods for induction and their attitudes in specific obstetric situations. RESULTS: The rate of induction varied between maternity units from 7.7% to 33% of deliveries. Most units used two (39.4%) or three or more (35.1%) agents for cervical ripening. In all, 87 (92.6%) units reported using dinoprostone as a vaginal slow-released insert, 59 units dinosprostone as a vaginal gel (62.8%) and 46 units a balloon catheter (48.9%). Only three units reported using vaginal misoprostol. Inductions without medical indication were reported by 71 (75.5%) maternity units, and 22 (23.4%) units even when the cervix was unfavourable. Obstetric attitudes in cases of breech presentation, previous caesareans, fetal growth restriction or macrosomia and prelabour rupture of the membranes varied widely. DISCUSSION: The variability of practices for induction of labour and the persistence of disapproved practices call for an assessment of the effectiveness and the safety of the different strategies. PMID- 29196155 TI - Assessment of liver function in pregnant anemic women upon oral iron and folic acid supplementation. AB - Oral iron therapy is the most widely prescribed treatment for iron deficiency anemia. However, oral iron supplementation may also lead to various health problems. The recognition of these physiological variations is essential for the diagnosis of liver diseases during the course of pregnancy. Therefore, the objective of this study was to assess the variations in levels of routine liver function tests (LFTs) in pregnant women before and after iron and folic acid treatment. Iron and folic acid was supplemented to 500 normal pregnant anemic women (mild=200, moderate=200 and severe=100) and 100 age matched normal pregnant non-anemic as controls daily for 100 days. Blood index values and liver function parameters were precisely monitored. Hemoglobin (Hb), total protein (TP), iron (Fe), albumin and alkaline phosphatase (ALP) levels were found increased (P<0.001; P<0.01; P<0.05) after treatment in mild, moderate, severe and control, respectively. Lipid peroxidation (LPx), aspartate transaminase (AST) and alanine transaminase (ALT) were increased in pretreated mild, moderate and severe groups and further increased after all treated subjects. Moreover, gamma-glutamyl transpeptidase (GGT) was found to decrease in pre and posttreated subjects. Treatment with iron and folic acid although has remarkable efficacy for Hb and body iron stores although for the cost of increasing the associated compartment of total bilirubin, AST and ALT concomitant with decreased GGT levels. Data obtained from the present study provide new insights into the mandatory application of liver function tests likely to be monitored at regular and specific intervals during the course of pregnancy. PMID- 29196156 TI - Leiomyomatosis peritonealisis disseminata: Two unusual cases with literature review. AB - BACKGROUND: Leiomyomatosis peritonealis disseminata (LPD) is a rare benign disease characterized by numerous smooth muscle-like cell nodules disseminated among the abdominal cavity. The pathogenesis of LPD is not well-known; one hypothesis, widely reported, is parasitic LPD (after uterine myoma surgery). The role of hormonal status has been raised without any evidence yet confirmed. Lesions of LPD can mimic carcinomatosis and lead to an inappropriate treatment. Total and spontaneous regression of the nodules is sometimes reported. This benign disease is also associated with leiomyosarcoma or invasive lesions, leading to mechanical complication or death. CASES AND REVIEW: We report two additional cases. The first case occurred in a 78-year-old woman with a history of total hysterectomy for uterine myoma, and was revealed by a small bowel obstruction. Second case occurred in a 50-year-old non-menopausal woman suffering from obesity (BMI 61,7), with an incidental diagnostic of LPD during a surgical procedure and spontaneous full regression of the disease. We analyzed 165 articles. We fond 16 menopausal women with LPD, 5 patients with intestinal obstruction or peritonitis due to LPD and 5 cases with spontaneous regression of LPD lesions. Six cases of recurrence as leiomyosarcoma were found. CONCLUSION: Cases of LPD have been reported without uterine myoma history and could be from extrauterine origin. Hysterectomy and oophorectomy should not be performed in first line. Peritoneal cytology should be done in case of ascites. Recurrences as leiomyosarcoma are reported and occurs early and justify a close follow up the first years.

AB - OBJECTIVE: The main aim of this study is to evaluate operative and postoperative morbidity of laparoscopic pelvic lymphadenectomy as well as its potential impact on the postoperative management in patients with an intermediate-risk of endometrial cancer. METHODS: We did a retrospective study between January 2009 and December 2013. We included all patients operated by laparoscopy for endometrial cancer presumed to have an intermediate-risk of recurrence. Pelvic lymphadenectomy in this group of patients was performed at the discretion of operating surgeons. Patients were consequently divided into two groups according to whether or not pelvic lymphadenectomy was performed. We made a comparative analysis between these two groups. RESULTS: Overall, 116 patients were managed for endometrial cancer presumed to be intermediate-risk. Among these, 93 received treatment with laparoscopy and were included in the study. Patients' characteristics did not differ between the two groups. The mean duration of surgery was significantly longer when pelvic lymphadenectomy was performed. The average number of retrieved lymph nodes was 13 and we had seven patients with positive lymph nodes (10%). CONCLUSION: Pelvic lymphadenectomy allows a better postoperative classification for some patients without more complication. PMID- 29196158 TI - Prevalence of cholesteryl ester storage disease among hypercholesterolemic subjects and functional characterization of mutations in the lysosomal acid lipase gene. AB - Lysosomal acid lipase hydrolyzes cholesteryl esters and triglycerides contained in low density lipoprotein. Patients who are homozygous or compound heterozygous for mutations in the lysosomal acid lipase gene (LIPA), and have some residual enzymatic activity, have cholesteryl ester storage disease. One of the clinical features of this disease is hypercholesterolemia. Thus, patients with hypercholesterolemia who do not carry a mutation as a cause of autosomal dominant hypercholesterolemia, may actually have cholesteryl ester storage disease. In this study we have performed DNA sequencing of LIPA in 3027 hypercholesterolemic patients who did not carry a mutation as a cause of autosomal dominant hypercholesterolemia. Functional analyses of possibly pathogenic mutations and of all mutations in LIPA listed in The Human Genome Mutation Database were performed to determine the pathogenicity of these mutations. For these studies, HeLa T-REx cells were transiently transfected with mutant LIPA plasmids and Western blot analysis of cell lysates was performed to determine if the mutants were synthesized in a normal fashion. The enzymatic activity of the mutants was determined in lysates of the transfected cells using 4-methylumbelliferone palmitate as the substrate. A total of 41 mutations in LIPA were studied, of which 32 mutations were considered pathogenic by having an enzymatic activity <10% of normal. However, none of the 3027 hypercholesterolemic patients were homozygous or compound heterozygous for a pathogenic mutation. Thus, cholesteryl ester storage disease must be a very rare cause of hypercholesterolemia in Norway. PMID- 29196160 TI - Quantitative functional evaluation of a 3D-printed silicone-embedded prosthesis for partial hand amputation: A case report. AB - STUDY DESIGN: A male patient with partial hand amputation of his nondominant hand, with only stumps of the proximal phalanx of the first and fifth finger, was evaluated. The performance of using two alternative 3D printed silicone-embedded personalized prostheses was evaluated using the quantitative Jebsen Hand Function Test. INTRODUCTION: Custom design and fabrication of 3D printed prostheses appears to be a good technique for improving the clinical treatment of patients with partial hand amputations. Despite its importance the literature shows an absence of studies reporting on quantitative functional evaluations of 3D printed hand prostheses. PURPOSE OF THE STUDY: We aim at producing the first quantitative assessment of the impact of using 3D printed silicone-embedded prostheses that can be fabricated and customized within the clinical environment. METHODS: Alginate molds and computed tomographic scans were taken from the patient's hand. Each candidate prosthesis was modeled in Computer Aided Design software and then fabricated using a combination of 3D printed parts and silicone-embedded components. DISCUSSION: Incorporating the patient's feedback during the design loop was very important for obtaining a good aid on his work activities. Although the explored patient-centered design process still requires a multidisciplinary team, functional benefits are large. CONCLUSION(S): Quantitative data demonstrates better hand performance when using 3D printed silicone-embedded prosthesis vs not using any aid. The patient accomplished complex tasks such as driving a nail and opening plastic bags. This was impossible without the aid of produced prosthesis. PMID- 29196161 TI - Effects of trapezius kinesio taping on scapular kinematics and associated muscular activation in subjects with scapular dyskinesis. AB - STUDY DESIGN: Crossover repeated-measure design. INTRODUCTION: Scapular dyskinesis rehabilitation programs that focus on inhibiting upper trapezius (UT) and activating the lower trapezius (LT) may assist in restoring scapular movements. We hypothesized that taping may be able to normalize scapular movements and associated muscular recruitment. PURPOSE OF THE STUDY: The purpose of this study was to investigate the immediate effects of kinesio taping over trapezius on scapular kinematics and muscular activation in different dyskinesis patterns. We expected that taping can improve scapular kinematics and muscular activation in subjects with dyskinesis. METHODS: Fifty-four participants with inferior angle prominence (pattern I), medial border prominence (pattern II), and mixed pattern (pattern I + II) were recruited. Kinesio taping was applied over 3 parts of trapezius muscles, including UT, middle trapezius (MT), and LT. The scapular kinematics and electromyographic data of trapezius and serratus anterior were collected during scapular plane elevation without taping and after each taping application. RESULTS: UT taping decreased UT activity (5%-7%; P = .001 .003) in 72% of participants with pattern II and pattern I + II dyskinesis, with increased posterior tipping (2.2 degrees -2.5 degrees ; P = .003) in pattern II dyskinesis. MT taping increased UT activity (3%; P = .003) in 48% of participants with pattern II dyskinesis. DISCUSSION: The taping over the trapezius muscle may help to restore coordinated scapular muscle balance and increased upward rotation of the scapula, especially in pattern II dyskinesis. Although no electromyography or kinematic difference was found with LT taping in each dyskinesis pattern, methods of applying LT taping need to be further investigated. CONCLUSION: Reduced UT muscle activity and scapular posterior tipping are appropriate when applying taping over UT muscle in patterns II and I + II dyskinesis. Caution should be taken when applying taping over MT and LT muscles in terms of increased UT activity, especially in pattern II dyskinesis. PMID- 29196159 TI - Cholesterol trafficking and raft-like membrane domain composition mediate scavenger receptor class B type 1-dependent lipid sensing in intestinal epithelial cells. AB - Scavenger receptor Class B type 1 (SR-B1) is a lipid transporter and sensor. In intestinal epithelial cells, SR-B1-dependent lipid sensing is associated with SR B1 recruitment in raft-like/ detergent-resistant membrane domains and interaction of its C-terminal transmembrane domain with plasma membrane cholesterol. To clarify the initiating events occurring during lipid sensing by SR-B1, we analyzed cholesterol trafficking and raft-like domain composition in intestinal epithelial cells expressing wild-type SR-B1 or the mutated form SR-B1-Q445A, defective in membrane cholesterol binding and signal initiation. These features of SR-B1 were found to influence both apical cholesterol efflux and intracellular cholesterol trafficking from plasma membrane to lipid droplets, and the lipid composition of raft-like domains. Lipidomic analysis revealed likely participation of d18:0/16:0 sphingomyelin and 16:0/0:0 lysophosphatidylethanolamine in lipid sensing by SR-B1. Proteomic analysis identified proteins, whose abundance changed in raft-like domains during lipid sensing, and these included molecules linked to lipid raft dynamics and signal transduction. These findings provide new insights into the role of SR-B1 in cellular cholesterol homeostasis and suggest molecular links between SR-B1 dependent lipid sensing and cell cholesterol and lipid droplet dynamics. PMID- 29196162 TI - Isolation of mammalian stress granule cores for RNA-Seq analysis. AB - Stress granules are dynamic, conserved non-translating RNA-protein assemblies that form during cellular stress and are related to pathological aggregates in many neurodegenerative diseases. Mammalian stress granules contain stable structures, referred to as "cores" that can be biochemically purified. Herein, we describe a step-by-step guide on how to isolate RNA from stress granule cores for RNA-Seq analysis. We also describe a methodology for validating the RNA-Seq results by single molecule FISH and how to quantify the single molecule FISH results. These protocols provide a starting point for describing the RNA content of stress granules and may assist in the discovery of the assembly mechanisms and functions of stress granules in a variety of biological contexts. PMID- 29196163 TI - The miR-182/SORT1 axis regulates vascular smooth muscle cell calcification in vitro and in vivo. AB - Arterial calcification is a common feature of cardiovascular disease. Sortilin is involved in the development of atherosclerosis, but the specific mechanism is unclear. In this study, we established calcification models in vivo and in vitro by using vitamin D3 and beta-glycerophosphate, respectively. In vivo, the expression of SORT1 was up-regulated and the expression of miR-182 was down regulated in calcified arterial tissues. Meanwhile there was a negative correlation between SORT1 expression and miR-182 levels. In vitro, downregulating SORT1 expression using shRNA inhibited beta-glycerophosphoric induced vascular smooth muscle cells (VSMCs) calcification. Moreover, reduced sortilin levels followed transfection of miR-182 mimics, whereas there was a significant increase in sortilin levels after transfection of miR-182 inhibitors. A luciferase reporter assay confirmed that SORT1 is the direct target of miR-182. Our study suggests that SORT1 plays a vital role in the development of arterial calcification and is regulated by miR-182. PMID- 29196165 TI - Osteopontin promotes collagen I synthesis in hepatic stellate cells by miRNA-129 5p inhibition. AB - Activation of hepatic stellate cells (HSCs) is an essential event in the initiation and progression of liver fibrosis. HSCs are believed to be the major source of collagen-producing myofibroblasts in fibrotic livers. A key feature in the pathogenesis of liver fibrosis is fibrillar Collagen I (Col 1) deposition. Osteopontin (OPN), an extracellular matrix (ECM) cytokine expressed in HSCs, could drive fibrogenesis by modulating the HSC pro-fibrogenic phenotype and Col 1 expression. Here, we aimed to investigate the molecular mechanism of OPN regulating the activation of HSCs. Our results showed that hepatic expression of OPN was increased in patients with liver fibrosis. In addition, hepatic OPN was positively correlated with Col 1 and alpha-SMA. Recombinant OPN (rOPN) upregulated Col 1 and alpha-SMA expression in LX-2 cells. However, OPN knockdown downregulated Col 1 expression. The 3'-UTR of the collagen 1 (Col 1) was identified to bind miR-129-5p. Transfection of miR-129-5p mimic in HSC resulted in a marked reduction of Col 1 expression. Conversely, a decrease in miR-129-5p in HSCs transfected by anti-sense miR-129-5p (AS-miR-129-5p) caused Col 1 upregulation. Furthermore, luciferase reporter assay showed that miR-129-5p directly target the 3'-UTR of Col1alpha1 mRNA via repressing its post transcriptional activities. Finally, miR-129-5p level was decreased in fibrotic liver of human, and reduced by rOPN treatment. In contrast, miR-129-5p was induced in HSCs transfected by OPN siRNA. These data suggested that OPN induces Col 1 expression via suppression of miR-129-5p in HSCs. PMID- 29196164 TI - Glucocorticoids indirectly decrease colon cancer cell proliferation and invasion via effects on cancer-associated fibroblasts. AB - Cancer-associated fibroblasts (CAFs) support cancer growth, invasion, and metastasis. Glucocorticoids (GCs), drugs often administered together with chemotherapy, are steroidal ligands of the glucocorticoid receptor (GR), a transcription factor which upon activation regulates expression of multiple genes involved in suppression of inflammation. We have previously shown that in dexamethasone (Dex)-treated CAFs derived from colon cancer, production and secretion of several factors related to cancer progression, such as tenascin C (TNC) and hepatocyte growth factor (HGF), were strongly suppressed. In this study we show that GCs can neutralize the cancer cell-promoting properties of CAFs. Conditioned medium from solvent-treated CAFs (CMCTRL) stimulates proliferation, motility and stretched morphotype of GR-deficient HCT8/E11 colon cancer cells. Yet, HCT8/E11 proliferation and stretched morphotype are impaired upon treatment with conditioned medium from Dex-treated CAFs (CMDEX), but HCT8/E11 cell migration is slightly increased under these conditions. Moreover, expression and potential activity of MMP-2 is also reduced in CMDEX compared with CMCTRL. These combined in vitro results concur with the results from in vivo chick chorioallantoic membrane assays, where the co-cultures of CAFs with colon cancer cells displayed impaired tumor formation and cancer cell invasion due to Dex administration. Combined, GC treatment influences cancer cell behavior indirectly through effects on CAFs. PMID- 29196166 TI - 1,25(OH)2D3 attenuates pulmonary arterial hypertension via microRNA-204 mediated Tgfbr2/Smad signaling. AB - Pulmonary arterial hypertension (PAH) is a devastating disease characterized by high pulmonary artery pressure. It is reported that microRNA-204 (miR-204) plays an important role in the development of PAH. Calcitriol [1,25-dihydroxyvitamin D3, 1,25(OH)2D3] mediates multiple pathophysiological processes. The aim of the current study was to explore the role of 1,25(OH)2D3 in PAH. PAH was induced in rats and rat pulmonary arterial endothelial cells (PAECs) were isolated as in vitro PAH model. The mean pulmonary artery pressure, morphologic changes, and expressions of transforming growth factor-beta1 (Tgfbr2), Smad2/7, alpha smooth muscle actin (alpha-SMA), and p21 were then measured. Furthermore, the effect of 1,25(OH)2D3 on rat PAECs with or without hypoxia treatment was also assessed by measuring the proliferation, migration, and cell cycle distribution of PAECs. The potential targets of miR-204 were also predicted and validated with a dual luciferase reporter system. Then the role of miR-204 and Tgfbr2 in the anti-PAH effect of 1,25(OH)2D3 was further explored by modulating the expression of the two genes. The overall pulmonary hypertension and hypoxia-induced proliferation and migration of PAECs were attenuated by administration of 1,25(OH)2D3, which was associated with the suppressed expressions of Tgfbr2, alpha-SMA, and Smad7 and induced expressions of miR-204, p21 and Smad2 both in vitro and in vivo. Moreover, the luciferase reporter assay identified Tgfbr2 as a novel direct target of miR-204. Both overexpression of miR-204 and inhibition of Tgfbr2 would strengthen the effect of 1,25(OH)2D3 administration. Findings outlined in the current study demonstrated that 1,25(OH)2D3 was a promising therapeutic modality for treatment of PAH, function of which was exerted through miR-204 mediated Tgfbr2 signaling. PMID- 29196167 TI - Cathepsin B links oxidative stress to the activation of NLRP3 inflammasome. AB - Oxidative stress-mediated activation of NLRP3 inflammasome in microglia is critical in the development of neurodegerative diseases such as Alzheimer's disease (AD), Parkinson disease (PD). However, the mechanism underlying oxidative stress activates NLRP3 inflammasome remains exclusive. Here we demonstrated cathepsin B (CTSB) as a regulator of the activation of NLRP3 inflammasome by H2O2.H2O2 induced IL-1beta secretion in NLRP3 inflammasome-dependent manner.H2O2 treatment increased CTSB activity, which in turn activated NLRP3 inflammasome, and subsequently processed pro-caspase-1 cleavage into caspase-1, resulting in IL 1 beta secretion. Genetic inhibition or pharmacological inhibition of CTSB blocked the cleavage of pro-caspase-1 into caspase-1 and subsequent IL-1 beta secretion induced by H2O2. Importantly, CTSB activity, IL-1beta levels and malondialdehyde (MDA) were remarkably elevated in plasma of AD patients compared to healthy controls, while glutathione was significantly lower than healthy controls. Correlation analyses showed that CTSB activity was positively correlated with IL-1beta and MDA levels, but negatively correlated with GSH levels in plasma of AD patients. Taken together, our results indicate that oxidative stress activates NLRP3 through upregulating CTSB activity. Our results identify an important biological function of CTSB in neuroinflammation, suggesting that CTSB is a potential target in AD therapy. PMID- 29196168 TI - Microscopic cuticle structure comparison of pupal melanic and wild strain of Spodoptera exigua and their gene expression profiles in three time points. AB - The beet armyworm, Spodoptera exigua (Hubner), is one of the major crop pests and is a target for current pest control approaches using insecticides. S. exigua melanic mutants (SEM) spontaneously occurred in the S. exigua wild type (SEW) strain and have been maintained under laboratory conditions on an artificial diet. Scanning electron microscopy showed that the inner cuticle of the SEM had a denser and less orderly structure. We investigated the cuticle protein genes using RNA-seq at three different developmental stages of both SEM and SEW. Comparison of cDNA libraries showed that 7257 CPs were significantly up-regulated and 664 genes were significantly downregulated in SEM at the developmental stage of 46-h in the fifth instar. In addition, 460 genes were significantly up regulated and 439 genes were significantly down-regulated in the SEM at the development stage of 4-h before pupation. Moreover, 162 genes were significantly up-regulated and 293 genes were significantly downregulated in the SEM, just after pupation. Two genes CPR63 and CPR97 were identified from RNA sequences to verify the differentially expressed gene (DEG) results through quantitative real time PCR (qRT-PCR). The results show that expression of both CPR63 and CPR97 structural cuticular proteins were significantly different between SEM and SEW. This functional analysis may help in understanding the role that these genes play in the cuticle pattern of the SEM. PMID- 29196169 TI - Purinergic system displays an anti-inflammatory profile in serum of silver catfish experimentally infected with Streptococcus agalactiae: An attempt to ameliorate the inflammatory response. AB - The purinergic system is recognized to modulate extracellular adenosine triphosphate (ATP) and related nucleotides through the activities of triphosphate diphosphohydrolase (NTPDase), 5'-nucleotidase, and adenosine deaminase (ADA), thereby playing an essential role in the immunoregulation of inflammatory and immune responses. Thus, the aim of this study was to evaluate whether the purinergic system can improve the inflammatory response in fish experimentally infected with Streptococcus agalactiae through the modulation of seric NTPDase, 5'-nucleotidase and ADA activities. Seric NTPDase (ATP as substrate) and 5' nucleotidase activities increased in silver catfish experimentally infected with S. agalactiae compared with the uninfected control group, while seric ADA activity decreased. Based on this evidence, our findings suggest that regulation of adenine nucleotide hydrolysis occurs in an attempt to restrict the inflammatory process and improve the immune system by hydrolyzing excess extracellular ATP. On the other hand, downregulation of seric ADA activity may be an attempt to augment extracellular adenosine (a molecule with anti-inflammatory effects) levels. In summary, the purinergic system is capable of modulating the immune and inflammatory responses during fish streptococcosis. PMID- 29196170 TI - Evaluation of phytochemical analysis and antimicrobial activities Allium essential oil against the growth of some microbial pathogens. AB - In this experimental study, the Allium essential oil (AHEO) was extracted through the hydrodistillation method. AHEO components were identified through gas chromatography/mass spectrometry (GC/MS), and its antioxidant properties and total phenolic content were examined through the methods of 2,2-diphenyl-1 picrylhydrazyl (DPPH), beta-carotene/linoleic acid inhibition and Folin Ciocalteu, respectively. The antimicrobial effect of AHEO was evaluated on Pseudomonas aeruginosa, Escherichia coli, Bacillus cereus, Bacillus subtilis, Staphylococcus aureus, Streptococcus pyogenes, and Candida albicans through the methods of well diffusion, disk diffusion, minimum inhibitory concentration, and minimum bactericidal/fungicidal concentration. Phytochemical constituents (alkaloids, tannins, saponins, flavone and glycosides) were evaluated. 5 chloroorcylaldehyde with a percentage of 45.6% was the major compound of AHEO. Increasing concentration of AHEO had a significant effect (p <= 0.05) on inhibition zone diameter. The MICs of the AHEO varied from 0.25 mg/ml to 2 mg/ml. The MBCs/MFCs of the AHEO varied from 0.25 mg/ml to 4 mg/ml. The results of phytochemical screening of AHEO showed the existence of alkaloids, tannins, saponins, flavone and glycosides. There was also little difference between disk diffusion and well diffusion methods, and the data was well distributed throughout the X and Y components. PMID- 29196172 TI - In silico identification and construction of microbial gene clusters associated with biodegradation of xenobiotic compounds. AB - Chemical substances not showing any importance in existence of biological systems and causing serious health hazards may be designated as Xenobiotic compound. Elimination or degradation of these unwanted substances is a major issue of concern for current time research. Process of biodegradation is a very important aspect of current research as discussed in current manuscript. Current study focuses on the detailed mining of data for the construction of microbial consortia for wide range of xenobiotics compounds. Intensive literature search was done for the construction of this library. Desired data was retrieved from NCBI in fasta format. Data was analysed through homology approaches by using BLAST. This homology based searched enriched with a great vision that not only bacterial population but many other cheap and potential sources are available for different xenobiotic degradation. Though it was focused that bacterial population covers a major part of biodegradation which is near about 90.6% but algae and fungi are also showing promising future in degradation of some important xenobiotic compounds. Analysis of data reveals that Pseudomonas putida has potential for degrading maximum compounds. Establishment of correlation through cluster analysis signifies that Pseudomonas putida, Aspergillus niger and Skeletonema costatum can have combined traits that can be used in finding out actual evolutionary relationship between these species. These findings may also givea new outcome in terms of much cheaper and eco-friendly source in the area of biodegradation of specified xenobiotic compounds. PMID- 29196171 TI - Nano silver particle synthesis using Swertia paniculata herbal extract and its antimicrobial activity. AB - In the present study, green synthesis of silver nanoparticles (AgNPs) is demonstrated using medicinal herb Swertia paniculata extract. The plant extract acted both as reducing and capping agents during synthesis process, where silver nitrate was used as silver source. Subsequent analysis revealed that particles had size range between 31 and 44 nm and were spherical in shape. Among reaction parameters, temperature and time had significantly influenced the synthesis reaction. Also, synthesized nanoparticles were found stable up to 90 days. Further, antimicrobial activity against gram negative and gram positive bacterial strains was done and results showed that synthesized AgNPs had better antimicrobial activity against Pseudomonas aeruginosa, Klebsiella pneumoniae under standard incubation conditions. Study shows that these particles can be very promising in biomedical applications in future. PMID- 29196173 TI - Characterization of pathogenic roles of two Erysipelothrix rhusiopathiae surface proteins. AB - Erysipelothrix rhusiopathiae is the causative agent of animal erysipelas and human erysipeloid. E. rhusiopathiae HP0728 and HP1472 have been reported to be down regulated in low-virulence or avirulent strains, but their pathogenic roles are not known. In this study, it was found that E. rhusiopathiae HP0728 and HP1472 were displayed on the surface of E. rhusiopathiae. Moreover, recombinant HP1472 could adhere to pig vascular endothelial cells. Recombinant HP0728 could bind host plasminogen but could not bind fibronectin. In conclusion, our work suggested that HP0728 and HP1472 are virulence factors of E. rhusiopathiae. PMID- 29196174 TI - The prevalence and drug resistance pattern of extended spectrum beta-lactamases (ESBLs) producing Enterobacteriaceae in Africa. AB - Extended spectrum beta-lactamases (ESBLs) are a group of enzymes that can hydrolyze a variety of beta-lactams including fourth generation cephalosporins and compromise the efficacy of all beta-lactams, except cephamycins and carbapenems. In the worldwide, the ESBL group of enzymes are found widely and causes a severe infection on human health which leads to various diseases. This review primarily focusses on analyzing the prevalence and drug resistance patterns in the African continent. From the earlier reported data shown only the minimal amount of surveillance information's has been summarized with respect to antimicrobial resistance on ESBLs producing Enterobacteriaceae both in hospital and community settings. To bring the present scenario in limelight, the present study explores the prevalence of ESBL-producing Enterobacteriaceae in various countries in Africa and specifically, to identify most common ESBL genes in hospital and community. The observation was initiated with the exhaustive literature search using PubMed and other databases to broaden the study from the earlier investigations in the African countries concerned about the prevalence rate of ESBL producing Enterobacteriaceae. Further, this study was extended to review various hypothesis of the hydrolytic mechanism, which was detailed by several authors performed earlier through computational approaches. Interestingly, the ESBLs class A and D were found to be common classes in Africa, with the gene CTX-M-15 being most prevalent. Notably, the present review highlights the prevalence on individual countries in Africa and it is extremely significant to prevent the dissemination of ESBL-producing Enterobacteriaceaea. Hence, this review on surveillance will be the benchmark to enhance the research on antimicrobial resistance patterns for all classes and genes. Furthermore, explored in-sights in this paper will be helpful for the further investigations to develop quicker, cost effective, and reliable diagnostic strategies and new effective therapies. PMID- 29196175 TI - Anti-tubercular and probiotic properties of coagulase-negative staphylococci isolated from Koozh, a traditional fermented food of South India. AB - In the last few years, the demand for the tremendous therapeutic applications of indigenous probiotic bacteria from diversified fermented food products has surged. In view of this, the present study was documented to evaluate the anti tubercular and probiotic properties of coagulase-negative staphylococci (CNS) indigenous to Koozh, a traditional fermented food product of South India. A total of 18 isolates were purified from Koozh, and tested for anti-tubercular activity against Mycobacterium tuberculosis H37Rv using luciferase reporter phage (LRP) assay. Among them, six isolates revealed higher percentage (>90%) of relative light unit (RLU) reduction. These six isolates were further evaluated for their in vitro probiotic attributes using standard protocols. All six staphylococci strains disclosed good probiotic properties. Moreover, Staphylococcus hominis strain MANF2 showed high cell survival percentage (92.2%) at pH 2.0 as well as towards simulated gastric juice (88.51%). Furthermore, strain MANF2 was found to be resistant to bile salt after 24 h of incubation with maximal viability of 5.71 +/- 0.02 log cfu/mL, and depicted the deconjugation of bile salt as well. All the isolates exhibited strong auto-aggregation capacity (44.4 +/- 1.2-68.1 +/- 1.5%), and hydrophobicity against toluene (55.0 +/- 1.2-72.0 +/- 1.1%). Additionally, strain MANF2 was observed to be highly resistant to phenol (6.27 +/- 0.01 log cfu/mL) and lysozyme (81.1 +/- 1.6% viability). Most importantly, all six isolates depicted good hypocholesterolemic effect, slight beta-galactosidase activity, and moderate proteolytic property. The strains were sensitive to all the tested conventional antibiotics, except Nalidixic acid. In addition to this, all staphylococci strains demonstrated significant DPPH (2,2-Diphenyl-1 picrylhydrazyl) scavenging, hydrogen peroxide tolerance, and hydroxyl radical scavenging activity in a dose dependent manner, thereby exhibiting the potent antioxidative properties of isolates. The negative results obtained from haemolytic, DNase, and gelatinase tests revealed the non-pathogenicity and safety aspect of these strains. In a nutshell, the present investigation divulges the persuasive anti-tubercular and probiotic properties of staphylococci, particularly strain MANF2, and recommended the further exploitation of Koozh associated CNS in pharmaceutics. PMID- 29196176 TI - Assessing value in breast reconstruction: A systematic review of cost effectiveness studies. AB - INTRODUCTION: Breast reconstruction is one of the most common procedures performed by plastic surgeons and is achieved through various choices in both technology and method. Cost-effectiveness analyses are increasingly important in assessing differences in value between treatment options, which is relevant in a world of confined resources. A thorough evaluation of the cost-effectiveness literature can assist surgeons and health systems evaluate high-value care models. METHODS: A systematic review of PubMed, Web of Science, and the Cost Effectiveness Analysis Registry was conducted. Two reviewers independently evaluated all publications up until August 17, 2017. RESULTS: After removal of duplicates, 1996 records were screened, from which 53 studies underwent full text review. All the 13 studies included for final analysis mention an incremental cost-effectiveness ratio. Five studies evaluated the cost-effectiveness of technologies including acellular dermal matrix (ADM) in staged prosthetic reconstruction, ADM in direct-to-implant (DTI) reconstruction, preoperative computed tomography angiography in autologous reconstruction, indocyanine green dye angiography in evaluating anastomotic patency, and abdominal mesh reinforcement in abdominal tissue transfer. The remaining eight studies evaluated the cost-effectiveness of different reconstruction methods. Cost-effective strategies included free vs. pedicled abdominal tissue transfer, DTI vs. staged prosthetic reconstruction, and fascia-sparing variants of free abdominal tissue transfer. CONCLUSIONS: Current evidence demonstrates multiple cost-effective technologies and methods in accomplishing successful breast reconstruction. Plastic surgeons should be well informed of such economic models when engaging payers and policymakers in discussions regarding high-value breast reconstruction. PMID- 29196177 TI - Muscarinic receptors in the nucleus accumbens shell play different roles in context-induced or morphine-challenged expression of behavioral sensitization in rats. AB - Both drug-related cues and drug priming are the main factors that induce relapse of drug addiction. Previous research has reported that blockade of the muscarinic receptors could significantly depress addictive behavior, suggesting that the muscarinic receptors might be involved in drug use and relapse behavior. The nucleus accumbens (NAc), especially the shell of the NAc, where the muscarinic receptors are expressed, is critical for craving and relapse. This study investigated the effects of microinfusion of the muscarinic receptor antagonist scopolamine into the NAc shell on context- and morphine-induced expression of behavioral sensitization. Behavioral sensitization was established by exposure to 5mg/kg morphine once daily for five consecutive days. Expression of behavioral sensitization was induced by saline challenge or 5mg/kg morphine challenge. The results showed that: (a) the muscarinic receptor antagonist scopolamine (10.8MUg/rat) microinjected into the NAc shell blocked expression of conditional sensitization; (b) acetylcholinesterase inhibitor huperzine-A (0.5 and 0.1MUg/rat), but not scopolamine (10.8MUg/rat), microinjected into the NAc shell blocked morphine-induced expression of sensitization; and (c) pre-infusion of scopolamine (10.8MUg/rat) reversed the inhibitory effect of huperzine-A (0.5MUg/rat) on morphine-induced sensitization. Our findings suggest that muscarinic receptors in the NAc shell play different roles in context-induced and morphine-challenged expression of behavioral sensitization. PMID- 29196179 TI - Urethral recurrence after radical cystectomy for urothelial carcinoma: A systematic review and meta-analysis. AB - PURPOSE: Currently, identified factors for urethral recurrence (UR) are based on individual reporting which has displayed controversy. In addition, risk of UR is one of the limiting factors to offer neobladder diversion during radical cystectomy (RC). We aim to systematically evaluate the incidence and risk factors of UR post-RC and its effect on survival. MATERIALS AND METHODS: A systematic online search was conducted according to PRISMA statement for publications reporting on UR after RC. From initial 802 results, 14 articles including 6169 patients were included finally after exclusion of ineligible studies. RESULTS: The incidence rate of UR was 4.4% (1.3%-13.7%). It was significantly lower with neobladder diversion (odds ratio = 0.44, 95% CI: 0.24-0.79, P = 0.006). Muscle invasion (hazard ratio = 1.18, 95% CI: 0.86-1.62, P = 0.31), carcinoma in situ (hazard ratio 0.97, 95% CI: 0.64-1.47, P = 0.88), prostatic stromal involvement (hazard ratio = 2.26, 95% CI: 0.01-627.75, P = 0.78), and prostatic urethral involvement (hazard ratio = 2.04, 95% CI: 0.20-20.80, P = 0.55) have no significant effect on UR. Men displayed tendency toward higher incidence of UR (odds ratio = 2.21, 95% CI: 0.96-5.06, P = 0.06). Absence of recurrence displayed tendency toward better disease specific survival, yet not significant (hazard ratio = 0.84, 95% CI: 0.66-1.08, P = 0.17). These results are limited by the retrospective nature of the included studies. CONCLUSION: Muscle invasion, carcinoma in situ and prostatic stromal or urethral involvement at time of RC have no significant effect on UR. Orthotopic neobladder is associated with a significant lower risk of UR after RC. PMID- 29196178 TI - Long-Term Remissions of Patients With Follicular Lymphoma Grade 3 Treated With R CHOP. AB - BACKGROUND: The optimal management of patients with follicular lymphoma Grade 3 (FLG3) is controversial. PATIENTS AND METHODS: This is a case series of 45 patients with FLG3 treated with first-line R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) and observed for an extended time interval. RESULTS: The overall response rate was 100% and the median progression free survival (PFS) has not been reached, with a 3-year PFS of 70%; 14 (31%) patients relapsed, nearly all within 3 years. The baseline characteristic more strongly associated with a shorter PFS were lymph >4 node sites and presence of B symptoms. Three patients later progressed to diffuse large B cell lymphoma, all had baseline elevated serum lactate dehydrogenase level and high International Prognostic Index score. Median overall survival has not been reached. All 4 patients who later developed acute myeloid leukemia were older than 60 years at the time of start of therapy. CONCLUSION: R-CHOP is an effective first-line treatment for patients with FLG3, and might provide extended PFS, comparable with outcomes observed in diffuse large B-cell lymphoma, particularly in subgroups with limited nodal disease. PMID- 29196180 TI - Unraveling the cell-type dependent radiosensitizing effects of gold through the development of a multifunctional gold nanoparticle. AB - The radiosensitizing efficacy of gold is well established, however, there remain several significant barriers to the successful clinical translation of nano-sized gold particles (AuNPs). These barriers include: retaining stability in relevant biological sera, demonstrating effectiveness at clinically relevant AuNP concentrations and identifying the biological context where significant benefit is most likely to be achieved. Herein we have developed a AuNP preparation, stress-tested to provide effective protection from salt and serum mediated agglomeration. Furthermore, the core AuNP is co-functionalized with two biologically derived peptides designed to enhance endocytosis and promote endosomal escape, thus maximizing intracellular AuNP surface area. In summary, these investigations demonstrate restored AuNP internalization using the co functionalized preparation that generated significant radiosensitization, in both in vitro and in vivo models, at clinically viable treatment concentrations. Furthermore, we have identified an underpinning biological mechanism in the inherent radical scavenging capacity that could be used to predict radiosensitizing efficacy. PMID- 29196181 TI - Cyclopeptide Dmt-[D-Lys-p-CF3-Phe-Phe-Asp]NH2, a novel G protein-biased agonist of the mu opioid receptor. AB - Opioid peptides and alkaloid drugs such as morphine, mediate their analgesic effects, but also undesired side effects, mostly through activation of the mu opioid receptor which belongs to the G protein-coupled receptor (GPCR) family. A new important pharmacological concept in the field of GPCRs is biased agonism. Two mu receptor ligands, Dmt-c[D-Lys-Phe-Phe-Asp]NH2 (C-36) and Dmt-c[D-Lys-Phe-p CF3-Phe-Asp]NH2 (F-81), were evaluated in terms of their ability to promote or block mu receptor/G protein and mu receptor/beta-arrestin interactions. Using the bioluminescence resonance energy transfer (BRET) assay it was shown that C-36 activated both, G protein and beta-arrestin pathways. Incorporation of trifluoromethyl group into the aromatic ring of phenylalanine in the sequence of F-81 led to activation of G-protein pathway rather than beta-arrestin recruitment. Opioid cyclopeptide F-81 turned out to be a biased G protein mu receptor agonist. Such biased ligands are able to separate the biological actions of an activated receptor and have the potential to become more effective drug candidates with fewer side effects. PMID- 29196182 TI - Peripheral 5-HT3 mediates mirror-image pain by a cross-talk with acid-sensing ion channel 3. AB - Mirror-image pain (MIP), which occurs along with complex regional pain syndrome, rheumatoid arthritis and chronic migraine, is characterized by increased pain sensitivity of healthy body regions other than the actual injured or inflamed sites. A high level of peripheral inflammation may activate central or peripheral glia, triggering mirror-image pain. However, which receptors mediate inflammatory signals to contribute glial activation remains unclear. Intraplantarly injecting mice with 5-hydroxytryptamine (5-HT) or acidic buffer (proton) caused only unilateral hyperalgesia, but co-injection of 5-HT/acid induced bilateral hyperalgesia (MIP). Blocking 5-HT3 or acid-sensing ion channel 3 (ASIC3) abolished satellite glial activation, inhibiting MIP. Interestingly, intraplantar administration of a 5-HT3 agonist induced MIP, and 5-HT3-mediated MIP can be reversed by a 5-HT3 antagonist or an ASIC3 blocker. Similar results were found using a ASIC3 agonist. Furthermore, 5-HT3 was observed to co-localize with ASIC3 in DRG neurons; 5-HT3 activation-induced an increase in intracellular calcium that was inhibited by an ASIC3 blocker and vice versa. A cross-talk between 5-HT3 and ASIC3 mediates satellite glial activation, thereby triggering mirror-image pain. PMID- 29196183 TI - NMDA receptor antagonist rodent models for cognition in schizophrenia and identification of novel drug treatments, an update. AB - Negative and cognitive deficit symptoms in schizophrenia remain an unmet clinical need. Improved understanding of the neuro- and psychopathology of cognitive dysfunction in the illness is urgently required to enhance the development of new improved therapeutic strategies. Careful validation of animal models that mimic the behaviour and pathology of complex psychiatric disorders is an essential step towards this goal. Non-competitive NMDAR (N-Methyl-d-aspartate receptor) antagonists e.g. phencyclidine (PCP), ketamine and dizocilpine (MK-801) can effectively replicate certain aspects of negative and cognitive deficits associated with schizophrenia in animals. In 2010 we reviewed the effects of NMDAR antagonism in tests for domains of cognition affected in schizophrenia, social behaviour and neuropathology, and in 2014, in tests for negative symptoms. In this update, we evaluate the most recent pharmacological strategies for restoring cognition in schizophrenia using NMDAR antagonist models, published since our original review in 2010 (cited over 225 times, excluding self citations). Tests reviewed are, novel object recognition for visual recognition memory, attentional set shifting for executive function, and operant tests incorporating recent touchscreen technology for a range of domains including working memory, problem solving and attention, all impaired in schizophrenia. Moreover, we include an update on parvalbumin (PV)-expressing GABAergic interneurons and review, for the first time, the effects of NMDAR antagonists on gamma oscillations, circuitry integral for effective cognition. Data summarized in this review strongly confirm the reliability and usefulness of NMDAR antagonist animal models for evaluating novel therapeutic candidates, and for improving our understanding of the pathophysiology of cognitive deficits in schizophrenia. This article is part of the Special Issue entitled 'Psychedelics: New Doors, Altered Perceptions'. PMID- 29196184 TI - A Randomized Trial of a Binocular iPad Game Versus Part-Time Patching in Children Aged 13 to 16 Years With Amblyopia. AB - PURPOSE: To compare visual acuity (VA) improvement in teenagers with amblyopia treated with a binocular iPad game vs part-time patching. METHODS: One hundred participants aged 13 to <17 years (mean 14.3 years) with amblyopia (20/40 to 20/200, mean ~20/63) resulting from strabismus, anisometropia, or both were enrolled into a randomized clinical trial. Participants were randomly assigned to treatment for 16 weeks of either a binocular iPad game prescribed for 1 hour per day (n = 40) or patching of the fellow eye prescribed for 2 hours per day (n = 60). The main outcome measure was change in amblyopic eye VA from baseline to 16 weeks. RESULTS: Mean amblyopic eye VA improved from baseline by 3.5 letters (2 sided 95% confidence interval [CI]: 1.3-5.7 letters) in the binocular group and by 6.5 letters (2-sided 95% CI: 4.4-8.5 letters) in the patching group. After adjusting for baseline VA, the difference between the binocular and patching groups was -2.7 letters (95% CI: -5.7 to 0.3 letters, P = .082) or 0.5 lines, favoring patching. In the binocular group, treatment adherence data from the iPad device indicated that only 13% of participants completed >75% of prescribed treatment. CONCLUSIONS: In teenagers aged 13 to <17 years, improvement in amblyopic eye VA with the binocular iPad game used in this study was not found to be better than patching, and was possibly worse. Nevertheless, it remains unclear whether the minimal treatment response to binocular treatment was owing to poor treatment adherence or lack of treatment effect. PMID- 29196186 TI - Implementation of an expanded point-of-care site inspection checklist in an academic medical center: An eight year experience. AB - BACKGROUND: We evaluated the effectiveness of an expanded point-of-care (POCT) site inspection checklist over an extended 8-y period. METHODS: A retrospective review of site inspection deficiency reports in a large academic medical center from 2010 to 2017 (year to date). RESULTS: There was a significant decrease in the number of cited deficiencies per site/inspection from 2010 (3.17) to 2017 (0.27) (p<0.001). The percentage of sites without deficiencies steadily increased from 2010 (8.7%) to 2017 (80.7%) (p<0.001). The most common citation was documentation of competency assessment followed by results documentation and annual procedure review. CONCLUSIONS: Regular inspections of sites performing POCT are necessary to maintain regulatory compliance. Over time significant improvements in compliance are achievable. PMID- 29196185 TI - Serum S100A12 and 30-day mortality after acute intracerebral hemorrhage. AB - BACKGROUND: S100A12 is implicated in inflammatory reactions. The purpose of this study was to determine the association between serum S100A12 concentrations and 30-day mortality in patients with acute intracerebral hemorrhage (ICH). METHODS: We prospectively included 182 healthy controls and 182 ICH patients within 24h after stroke onset. Serum samples were collected for the measurement of S100A12 concentrations. Multivariable analysis was used to evaluate the relationship between serum S100A12 concentrations and mortality of ICH patients within 30days. RESULTS: Serum S100A12 concentrations were significantly increased compared to control subjects. S100A12 concentrations were positively correlated with National Institutes of Health Stroke Scale (NIHSS) score, ICH volume, blood glucose concentrations, blood white blood cell count and plasma C-reactive protein concentrations. 36 (19.8%) patients were deceased within 30days after stroke onset. Non-survivors had significantly higher concentrations of serum S100A12 than survivors. Additionally, Serum S100A12 concentrations significantly discriminated patients at risk of 30-day mortality and its predictive value was equivalent to those of NIHSS score and hematoma volume. Moreover, higher serum S100A12 concentrations showed a significantly higher risk for 30-day mortality and overall survival. CONCLUSIONS: Higher S100A12 concentrations are positively associated with inflammation, hemorrhagic severity and short-term mortality among ICH patients, indicating S100A12 may represent a biomarker for predicting poor outcome after hemorrhagic stroke. PMID- 29196187 TI - Clinical proteomics: Insights from IGF-I. AB - Clinical proteomics aims to deliver cost-effective multiplexing of potentially hundreds of diagnostic proteins, including distinct protein isoforms. The analytical strategy known as targeted proteomics is particularly promising because it is compatible with robust mass spectrometry (MS)-platforms already implemented in many clinical laboratories for routine quantitation of small molecules (i.e. uHPLC coupled to triple-quadrupole MS). Progress in targeted proteomics of circulating insulin-like growth factor 1 (IGF-I) have provided valuable insights about tryptic peptides, transitions, internal standards and calibrants. The present challenge is to examine if targeted proteomics of IGF-I can truly measure up to the routine performance that must be expected from a clinical testing platform. PMID- 29196188 TI - Nervous system development and disease: A focus on trithorax related proteins and chromatin remodelers. AB - The nervous system comprises many different cell types including neurons, glia, macrophages, and immune cells, each of which is defined by specific patterns of gene expression, morphology, function, and anatomical location. Establishment of these complex and highly regulated cell fates requires spatial and temporal coordination of gene transcription. Open chromatin (euchromatin) allows transcription factors to interact with gene promoters and activate lineage specific genes, whereas closed chromatin (heterochromatin) remains inaccessible to transcriptional activation. Changes in the genome-wide distribution of euchromatin accompany transcriptional plasticity that allows the diversity of mature cell fates to be generated during development. In the past 20years, many new genes and gene families have been identified to participate in regulation of chromatin accessibility. These genes include chromatin remodelers that interact with Trithorax group (TrxG) and Polycomb group (PcG) proteins to activate or repress transcription, respectively. Here we review the role of TrxG proteins in neurodevelopment and disease. PMID- 29196191 TI - Arterial spin labeling perfusion MRI signal denoising using robust principal component analysis. AB - BACKGROUND: Arterial spin labeling (ASL) perfusion MRI provides a non-invasive way to quantify regional cerebral blood flow (CBF) and has been increasingly used to characterize brain state changes due to disease or functional alterations. Its use in dynamic brain activity study, however, is still hampered by the relatively low signal-to-noise-ratio (SNR) of ASL data. NEW METHOD: The aim of this study was to validate a new temporal denoising strategy for ASL MRI. Robust principal component analysis (rPCA) was used to decompose the ASL CBF image series into a low-rank component and a sparse component. The former captures the slowly fluctuating perfusion patterns while the latter represents spatially incoherent spiky variations and was discarded as noise. While there still lacks a way to determine the parameter for controlling the balance between the low-rankness and sparsity of the decomposition, we designed a method to solve this problem based on the unique data structures of ASL MRI. Method evaluations were performed with ASL CBF-based functional connectivity (FC) analysis and a sensorimotor functional ASL MRI study. COMPARISON WITH EXISTING METHOD(S): The proposed method was compared with the component based noise correction method (CompCor). RESULTS: The proposed method markedly increased temporal signal-to-noise-ratio (TSNR) and sensitivity of ASL CBF images for FC analysis and task activation detection. CONCLUSIONS: We proposed a new temporal ASL CBF image denoising method, and showed its benefit for the CBF time series-based FC analysis and task activation detection. PMID- 29196190 TI - p-Benzoquinone-induced aggregation and perturbation of structure and chaperone function of alpha-crystallin is a causative factor of cigarette smoke-related cataractogenesis. AB - Cigarette smoking is a significant risk factor for cataract. However, the mechanism by which cigarette smoke (CS) causes cataract remains poorly understood. We had earlier shown that in CS-exposed guinea pig, p-benzoquinone (p BQ) derived from CS in the lungs is carried by the circulatory system to distant organs and induces various smoke-related pathogeneses. Here, we observed that CS exposure caused accumulation of the p-BQ-protein adduct in the eye lens of guinea pigs. We also observed accumulation of the p-BQ-protein adduct in resected lens from human smokers with cataract. No such accumulation was observed in the lens of never smokers. p-BQ is a strong arylating agent that forms Michael adducts with serum albumin and haemoglobin resulting in alterations of structure and function. A major protein in the mammalian eye lens is alphaA-crystallin, which is a potent molecular chaperone. alphaA-crystallin plays a key role in maintaining the integrity and transparency of the lens. SDS-PAGE indicated that p BQ induced aggregation of alphaA-crystallin. Various biophysical techniques including UV-vis spectroscopy, fluorescence spectroscopy, FT-IR, bis-ANS titration suggested a perturbation of structure and chaperone function of alphaA crystallin upon p-BQ modification. Our results indicate that p-BQ is a causative agent involved in the modification of alphaA-crystallin and pathogenesis of CS induced cataract. Our findings would educate public about the impacts of smoking on eye health and help to discourage them from smoking. The study might also help scientists to develop new drugs for the intervention of CS-induced cataract at an early stage.

PMID- 29196189 TI - PD-L1, inflammation, non-coding RNAs, and neuroblastoma: Immuno-oncology perspective. AB - Neuroblastoma is the most common pediatric solid tumor of neural crest origin. The current treatment options for neuroblastoma produce severe side effects. Programmed death-ligand 1 (PD-L1), chronic inflammation, and non-coding RNAs are known to play a significant role in the pathogenesis of neuroblastoma. Cancer cells and the surrounding cells in the tumor microenvironment express PD-L1. Programmed death-1 (PD-1) is a co-receptor expressed predominantly by T cells. The binding of PD-1 to its ligands, PD-L1 or PD-L2, is vital for the physiologic regulation of the immune system. Chronic inflammation is involved in the recruitment of leukocytes, production of cytokines and chemokines that in turn, lead to survival, metastasis, and angiogenesis in neuroblastoma tumors. The miRNAs and long non-coding (lnc) RNAs have emerged as a novel class of non-coding RNAs that can regulate neuroblastoma associated cell-signaling pathways. The dysregulation of PD-1/PD-L1, inflammatory pathways, lncRNAs, and miRNAs have been reported in clinical and experimental samples of neuroblastoma. These signaling molecules are currently being evaluated for their potential as the biomarker and therapeutic targets in the management of neuroblastoma. A monoclonal antibody called dinutuximab (Unituxin) that attaches to a carbohydrate molecule GD2, on the surface of many neuroblastoma cells, is being used as an immunotherapy drug for neuroblastoma treatment. Atezolizumab (Tecentriq), an engineered monoclonal antibody against PD-L1, are currently in clinical trial for neuroblastoma patients. The lncRNA/miRNA-based therapeutics is being developed to deliver tumor suppressor lncRNAs/miRNAs or silencing of oncogenic lncRNAs/miRNAs. The focus of this review is to discuss the current knowledge on the immune checkpoint molecules, PD-1/PD-L1 signaling, inflammation, and non-coding RNAs in neuroblastoma. PMID- 29196192 TI - Macrovipecetin, a C-type lectin from Macrovipera lebetina venom, inhibits proliferation migration and invasion of SK-MEL-28 human melanoma cells and enhances their sensitivity to cisplatin. AB - BACKGROUND: The resistance of melanoma cells to cisplatin restricts its clinical use. Therefore, the search for novel tumor inhibitors and effective combination treatments that sensitize tumor cells to this drug are still needed. We purified macrovipecetin, a novel heterodimeric C-type lectin, from Macrovipera lebetina snake venom and investigated its anti-tumoral effect on its own or combined with cisplatin, in human melanoma cells. METHODS: Biochemical characterization, in vitro cells assays such as viability, apoptosis, adhesion, migration, invasion, Western blotting and in silico analysis were used in this study. RESULTS: Macrovipecetin decreased melanoma cell viability 100 times more than cisplatin. Interestingly, when combined with the drug, macrovipecetin enhanced the sensitivity of SK-MEL-28 cells by augmenting their apoptosis through increased expression of the apoptosis inducing factor (AIF) and activation of ERK1/2, p38, AKT and NF-kappaB. Moreover, macrovipecetin alone or combined with cisplatin induced the expression of TRADD, p53, Bax, Bim and Bad and down-regulated the Bcl 2 expression and ROS levels in SK-MEL-28 cells. Interestingly, these treatments impaired SK-MEL-28 cell adhesion, migration and invasion through modulating the function and expression of alphavbeta3 integrin along with regulating E-cadherin, vimentin, beta-catenin, c-Src and RhoA expression. In silico study suggested that only the alpha chain of macrovipecetin interacts with a region overlapping the RGD motif binding site on this integrin. CONCLUSIONS: We validated the antitumor effect of macrovipecetin when combined, or not, with cisplatin on SK-MEL-28 cells. GENERAL SIGNIFICANCE: The presented work proposes the potential use of macrovipecetin and cisplatin in combination as an effective anti-melanoma treatment. PMID- 29196194 TI - Molecular detection and sequence characterization of diverse rhabdoviruses in bats, China. AB - The Rhabdoviridae is among the most diverse families of RNA viruses and currently classified into 18 genera with some rhabdoviruses lethal to humans and other animals. Herein, we describe genetic characterization of three novel rhabdoviruses from bats in China. Of these, two viruses (Jinghong bat virus and Benxi bat virus) found in Rhinolophus bats showed a phylogenetic relationship with vesiculoviruses, and sequence analyses indicate that they represent two new species within the genus Vesiculovirus. The remaining Yangjiang bat virus found in Hipposideros larvatus bats were only distantly related to currently known rhabdoviruses. PMID- 29196195 TI - Novel expression of immunogenic foot-and-mouth disease virus-like particles in Nicotiana benthamiana. AB - Foot-and-mouth disease (FMD) is a highly contagious disease of cloven-hoofed animals and is endemic in Africa, parts of South America and southern Asia. The causative agent, FMD virus (FMDV) is a member of the genus Aphthovirus, family Picornaviridae. Vaccines currently used against FMDV are chemically inactivated virus strains which are produced under high-level biocontainment facilities, thus raising their cost. The development of recombinant FMDV vaccines has focused predominantly on FMDV virus-like particle (VLP) subunit vaccines for which promising results have been achieved. These VLPs are attractive candidates because they avoid the use of live virus in production facilities, but conserve the complete repertoire of conformational epitopes of the virus. Recombinant FMDV VLPs are formed by the expression and assembly of the three structural proteins VP0, VP1 and VP3. This can be attained by co-expression of the three individual structural capsid proteins or by co-expression of the viral capsid precursor P1 2A together with the viral protease 3C. The latter proteolytically cleaves P1-2A into the respective structural proteins. These VLPS are produced in mammalian or insect cell culture systems, which are expensive and can be easily contaminated. Plants, such as Nicotiana benthamiana, potentially provide a more cost-effective and very highly scalable platform for recombinant protein and VLP production. In this study, P1-2A was transiently expressed in N. benthamiana alone, without the 3C protease. Surprisingly, there was efficient processing of the P1-2A polyprotein into its component structural proteins, and subsequent assembly into VLPs. The yield was ~0.030MUg per gram of fresh leaf material. Partially purified VLPs were preliminarily tested for immunogenicity in mice and shown to stimulate the production of FMDV-specific antibodies. This study, has important implications for simplifying the production and expression of potential vaccine candidates against FMDV in plants, in the absence of 3C expression. PMID- 29196196 TI - Molluscicidal activity of Manilkara subsericea (Mart.) dubard on Biomphalaria glabrata (Say, 1818). AB - Schistosomiasis is promoted for species from Schistosoma genus affecting over 200 million people worldwide. Molluscicides are an efficient method to control this disease, being able to reduce intermediate host snail Biomphalaria glabrata number. In function of resistance cases using niclosamide, natural products are promisors to discover new drugs. Manilkara subsericea is endemic to Brazilian sandbanks of Rio de Janeiro State and wide ranges of biological activities. However, there is no studies evaluating its effects as molluscicidal agent. We tested crude extract from leaves of M. subsericea molluscicidal action, as well it ethyl-acetate fraction and isolated substances against B. glabrata. M. subsericea leaves crude extract and ethyl acetate fraction induced 80+/-4.13% and 86.66+/-4.59% mortality of adult snails at concentrations of 250ppm after 96h, and their LD50 values were 118.7+/-1.62 and 23.41+/-1.15ppm respectively. Isolated substances from M. subsericea were also considered active. Quercetin, myricetin and ursolic acid, at concentration of 100ppm (96h), were able to induce mortality levels of 100%, 80% and 53.33%, respectively. Our results suggest that M. subsericea can be considered promising as a molluscicide agent. PMID- 29196197 TI - Behavioral asymmetries in ticks - Lateralized questing of Ixodes ricinus to a mechatronic apparatus delivering host-borne cues. AB - Ticks are considered among the most dangerous arthropod vectors of disease agents to both humans and animals worldwide. Lateralization contributes to biological fitness in many animals, conferring important functional advantages, therefore studying its role in tick perception would critically improve our knowledge about their host-seeking behavior. In this research, we evaluated if Ixodes ricinus (L.) (Ixodiidae) ticks have a preference in using the right or the left foreleg to climb on a host. We developed a mechatronic device moving a tuft of fox skin with fur as host-mimicking combination of cues. This engineered approach allows to display a realistic combination of both visual and olfactory host-borne stimuli, which is prolonged over the time and standardized for each replicate. In the first experiment, the mechatronic apparatus delivered host-borne cues frontally, to evaluate the leg preference during questing as response to a symmetrical stimulus. In the second experiment, host-borne cues were provided laterally, in an equal proportion to the left and to the right of the tick, to investigate if the host direction affected the questing behavior. In both experiments, the large majority of the tested ticks showed individual-level left biased questing acts, if compared to the ticks showing right-biased ones. Furthermore, population-level left-biased questing responses were observed post exposure to host-mimicking cues provided frontally or laterally to the tick. Overall, this is the first report on behavioral asymmetries in ticks of medical and veterinary importance. Moreover, the mechatronic apparatus developed in this research can be exploited to evaluate the impact of repellents on tick questing in highly reproducible standardized conditions. PMID- 29196198 TI - Neurosurgical Modeling of Retinal Ischemia-Reperfusion Injury. AB - BACKGROUND: A reliable model of ischemia-reperfusion is required to evaluate the efficacy and safety of neuroprotective therapies for stroke. We present a novel reproducible pterygopalatine-ophthalmic artery ligation model of ischemia reperfusion injury in the retina. METHODS: Rats were subjected to ophthalmic artery/meningeal sheath ligation (OAML-standard method) or clamping of the pterygopalatine-ophthalmic artery (OAC-new method) for 30 minutes. Retinal ganglion cell (RGC) survival was assessed by prelabeling with FluoroGold (FG) (Santa Cruz Biotechnology, CA, USA) and RNA-binding protein with multiple splicing (RBPMS) at 14 days after ischemia, and all results were compared with a sham group (n = 7 in each group). RESULTS: RGC density in the normal-uninjured (FG-labeled) group was 2111 +/- 38 cells/mm2 (mean +/- standard error of mean) and that in the RBPMS-labeled group was 2142 +/- 35 cells/mm2. The OAML procedure significantly reduced RGC density to 738 +/- 23 cells/mm2 and 780 +/- 41 cells/mm2 (P < .001) in the FG-labeled and RBPMS-labeled groups, respectively. Similarly, OAC reduced RGC survival to 782 +/- 19 cells/mm2 and 813 +/- 22 cells/mm2 (P < .001) in the FG-labeled and RBPMS-labeled groups, respectively. RGC survival was similar following OAC and OAML models, suggesting that both induce comparable levels of damage. However, RGC survival in the OAC model was found to have less dispersion than OAML-induced ischemia. CONCLUSIONS: These results suggest that the OAC procedure is a reliable reproduction of ischemia reperfusion injury that mimics the effects of ophthalmic artery occlusion in humans and provides a useful research model for testing manipulations directed against pathways involved in RGC ischemic degeneration. PMID- 29196199 TI - Midt-Term Results after Fast-Track Prophylactic Carotid Surgery Program: The Risk of Overlooking Occult Cancer. AB - BACKGROUND: Most guidelines recommend fast-track carotid endarterectomy (CEA) within 14 days of the last ischemic event. Long-term survival after fast-track CEA is unknown. The purpose of this study was to determine whether the fast-track CEA program in our region was associated with a reduced or increased 2-year survival and overall complication rate in our population. METHODS: Prospective 2 year follow-up in patients after the implementation of a fast-track CEA program during a period of 31/2 years. Data on recurrent stroke, myocardial infarction, and death in a 2-year period after CEA were collected along with the indication for surgery and the time from ischemic event to the operation. RESULTS: Two hundred patients underwent CEA. The overall complication rate for 30 days was 3.5% (95% confidence interval [CI], 2%-5%) and 15.5% (95% CI, 13%-18%) for 2 years. During the 2-year follow-up 17 patients (8.5%; 95% CI, 7%-10%) died. Eight patients (4%; 95% CI, 2%-6%) died of advanced cancer (undiagnosed at the index event and CEA time). Of the 6 deaths occurring in patients undergoing CEA 14 days after the index event or earlier, 5 patients (83%; 95% CI, 55%-95%) died of advanced cancer. In the 11 deaths in patients who underwent CEA more than 14 days after the index event, 3 patients (27%; 95% CI, 5%-50%) died of cancer. This was a statistically significant difference (P = .049). CONCLUSION: Fast-track CEA is a safe procedure in selected patients. Our results show a potential significant risk of overlooking occult cancer, which may affect the long-term benefit from prophylactic CEA. PMID- 29196200 TI - Incidental Thrombotic Thrombocytopenic Purpura during Acute Ischemic Stroke and Thrombolytic Treatment. AB - BACKGROUND: Intravenous tissue plasminogen activator (IV tPA) was shown to be an effective treatment for acute ischemic stroke (AIS). According to stroke guidelines, there is no need to wait for the complete blood count (CBC) and coagulation test results before application of IV alteplase if there is no suspected coagulation disorder. In this study, a patient with AIS and thrombotic thrombocytopenic purpura (TTP) symptoms during thrombolytic treatment was presented. CASE: A 33-year-old male patient was admitted at the 2.5th hour of AIS symptoms onset with right hemiparesis and sensorimotor aphasia. Cranial computed tomography (CT) and diffusion magnetic resonance imaging did not reveal any abnormality. In his medical history, the patient did not have any contraindication for thrombolytic treatment. To avoid delays to thrombolytic therapy, blood samples were taken, and after that, IV bolus alteplase treatment was applied. During maintenance treatment, agitation and vomiting developed. The result of blood samples showed less than 26,000 mm3 platelet count and maintenance therapy was stopped. In control cranial CT, there was no hemorrhage. In the laboratory examination; anemia, low platelet count; increased indirect bilirubin, lactate dehydrogenase (LDH) levels were found, and fever was 38.4 degrees C. Schistocytes were observed in peripheral blood smear and the patient was diagnosed as TTP. CONCLUSIONS: Stroke guidelines recommend not to wait for the results of CBC and coagulation tests before IV tPA treatment in patients who do not have any history of coagulopathy disorder. If possible, before applying IV tPA we may wait for the results of coagulation and CBC tests, keeping in mind the diseaes with high mortality such as TTP. PMID- 29196202 TI - Node-making process in network meta-analysis of nonpharmacological treatment are poorly reported. AB - OBJECTIVE: To identify methods to support the node-making process in network meta analyses (NMAs) of nonpharmacological treatments. STUDY DESIGN AND SETTING: We proceeded in two stages. First, we conducted a literature review of guidelines and methodological articles about NMAs to identify methods proposed to lump interventions into nodes. Second, we conducted a systematic review of NMAs of nonpharmacological treatments to extract methods used by authors to support their node-making process. MEDLINE and Google Scholar were searched to identify articles assessing NMA guidelines or methodology intended for NMA authors. MEDLINE, CENTRAL, and EMBASE were searched to identify reports of NMAs including at least one nonpharmacological treatment. Both searches involved articles available from database inception to March 2016. From the methodological review, we identified and extracted methods proposed to lump interventions into nodes. From the systematic review, the reporting of the network was assessed as long as the method described supported the node-making process. RESULTS: Among the 116 articles retrieved in the literature review, 12 (10%) discussed the concept of lumping or splitting interventions in NMAs. No consensual method was identified during the methodological review, and expert consensus was the only method proposed to support the node-making process. Among 5187 references for the systematic review, we included 110 reports of NMAs published between 2007 and 2016. The nodes were described in the introduction section of 88 reports (80%), which suggested that the node content might have been a priori decided before the systematic review. Nine reports (8.1%) described a specific process or justification to build nodes for the network. Two methods were identified: (1) fit a previously published classification and (2) expert consensus. CONCLUSION: Despite the importance of NMA in the delivery of evidence when several interventions are available for a single indication, recommendations on the reporting of the node-making process in NMAs are lacking, and reporting of the node-making process in NMAs seems insufficient. PMID- 29196201 TI - Specific Factors to Predict Large-Vessel Occlusion in Acute Stroke Patients. AB - BACKGROUND: The effectiveness of thrombectomy for acute ischemic stroke has been established, and earlier treatment produces better outcomes. If possible to identify large-vessel occlusion (LVO) at the prehospital phase, eligible patients can be shipped directly to a hospital that can perform thrombectomy. The purpose of this study was to determine factors that are specific to LVO and can be known before hospital arrival. METHODS: The subjects were stroke patients during the period between July 2014 and June 2016, who had a National Institutes of Health Stroke Scale (NIHSS) score of 8 or higher and came to our hospital within 6 hours of onset. These patients were divided into an LVO group and a non-LVO group, and background factors, mode of onset, individual NIHSS item scores, and blood pressure at the time of the visit were retrospectively investigated. The selected factors were compared with LVO prediction scales reported in the past. RESULTS: There were 196 stroke patients who had NIHSS scores of 8 or higher and arrived at the hospital within 6 hours. Of these 196 patients, 56 had LVO. This LVO group included a significantly higher number of patients with the 2 items of atrial fibrillation (odds ratio [OR], 11.5: 95% confidence interval [CI], 4.04-32.9; P < .0001) and systolic blood pressure of 170 mm Hg or lower (OR, 2.99: 95% CI, 1.33 6.71, P = .008). These 2 items predicted LVO equally to existing LVO prediction scales. CONCLUSIONS: The 2 items of atrial fibrillation and systolic blood pressure of 170 mm Hg or lower were significantly correlated with LVO. PMID- 29196203 TI - Nuclear positioning: A matter of life. PMID- 29196204 TI - Underground cryptic speciation within the Maghreb: Multilocus phylogeography sheds light on the diversification of the checkerboard worm lizard Trogonophis wiegmanni. AB - Biogeographic and evolutionary patterns in the North African portion of the Western Palaearctic are poorly known. A high fraction of undescribed diversity is expected in this region, especially in groups such as reptiles. Here we used mitochondrial (12S, 16S, cytb) and nuclear (pomc, rag2, cmos) markers and morphological data to investigate phyletic diversification and phylogeographical structure in the amphisbaenian Trogonophis wiegmanni endemic to the Maghreb. Phylogenetic and molecular dating analyses based on gene trees and species trees support three deeply divergent lineages of Pliocene origin, two in Morocco and one in central Algeria and Tunisia. Parapatry, reciprocal monophyly, high genetic divergence and limited morphological differentiation between them suggest that these lineages represent independent cryptic taxonomic units. Emerging lines of evidence from this study and from available literature on Maghreb taxa support (i) a major biogeographic break between western and eastern Maghreb and (ii) a role of the Atlas as a biogeographic divide within the western Maghreb (Morocco). The origin of these biogeographic units is probably associated with the evolutionary events prompted by the Late Miocene palaeogeographic setting and later by Plio-Pleistocene climatic changes and their interplay with prominent orographic barriers within North Africa. PMID- 29196205 TI - Alternative methods of phylogenetic inference for the Patagonian lizard group Liolaemus elongatus-kriegi (Iguania: Liolaemini) based on mitochondrial and nuclear markers. AB - We present different approaches to a multi-locus phylogeny for the Liolaemus elongatus-kriegi group, including almost all species and recognized lineages. We sequenced two mitochondrial and five nuclear gene regions for 123 individuals from 35 taxa, and compared relationships resolved from concatenated and species tree methods. The L. elongatus-kriegi group was inferred as monophyletic in three of the five analyses (concatenated mitochondrial, concatenated mitochondrial + nuclear gene trees, and SVD quartet species tree). The mitochondrial gene tree resolved four haploclades, three corresponding to the previously recognized complexes: L. elongatus, L. kriegi and L. petrophilus complexes, and the L. punmahuida group. The BEAST species tree approach included the L. punmahuida group within the L. kriegi complex, but the SVD quartet method placed it as sister to the L. elongatus-kriegi group. BEAST inferred species of the L. elongatus and L. petrophilus complexes as one clade, while SVDquartet inferred these two complexes as monophyletic (although with no statistical support for the L. petrophilus complex). The species tree approach also included the L. punmahuida group as part of the L. elongatus-kriegi group. Our study provides detailed multilocus phylogenetic hypotheses for the L. elongatus-kriegi group, and we discuss possible reasons for differences in the concatenation and species tree methods.

AB - Tissue damage and inflammation are important triggers for regeneration and fibrosis. Tissue damage not only induces inflammation in general, it also determines the type and polarization of inflammation by recruiting and activating a variety of different cells types of the innate and adaptive immune system. This review focuses on the pathways leading from tissue damage to inflammation, from inflammation to fibrosis and from fibrosis to function. It covers the pro- and antifibrotic properties of immunological mediators released from T cells, monocytes/macrophages, innate lymphoid cells, basophils and eosinophils and takes into account that extracellular matrix proteins are not only produced by mesenchymal fibroblasts but also by other cell types, especially infiltrating hematopoietic cells. The special requirements for activation and recruitment of these so called fibrocytes are described in detail. PMID- 29196208 TI - eRADicAte: A Prospective Evaluation Combining Radium-223 Dichloride and Abiraterone Acetate Plus Prednisone in Patients With Castration-Resistant Prostate Cancer. AB - BACKGROUND: Multiple castration-resistant prostate cancer (CRPC) therapies are approved by the United States Food and Drug Administration. Radium-223 dichloride (Ra-223) with abiraterone acetate plus prednisone have different mechanisms of action and distinct off-target side-effect profiles. We prospectively investigated their combined safety, tolerability, and patient-reported outcome measures. PATIENTS AND METHODS: eRADicAte, an investigator-initiated, phase II trial, studied 31 patients with metastatic CRPC, from 5 United States uro oncology research sites. Patients completed 6 cycles of Ra-223 with concurrent abiraterone therapy. Quality of life and pain were assessed using the Functional Assessment of Cancer Therapy-Prostate and the Brief Pain Inventory-Short Form questionnaires and their subscales; we reported the number of subjects meeting standardized criteria for clinically meaningful improvements on each scale. Safety assessment included Eastern Cooperative Oncology Group performance status, laboratory changes, opioid use, radiographic responses, and adverse events (AEs). RESULTS: Twenty of 31 (65%) experienced positive clinically meaningful improvement changes on the Functional Assessment of Cancer Therapy-Prostate, and 25 (81%) of 31 on the Prostate Cancer Subscale. Eighteen (58%) of 31 demonstrated reduced pain intensity and 12 (39%) of 31 demonstrated reduction of pain interference in their lives. At baseline, subjects averaged 11.6 +/- 2.8 bone lesions; at the end of treatment, subjects averaged 5.6 +/- 2.4 bone lesions (P = .0002). The most frequent AEs were diarrhea (17%), nausea (17%), and fatigue (14%). There were 6 serious AEs; 1 led to study withdrawal. CONCLUSIONS: Patients experienced clinically meaningful improvements in quality of life and pain, without unexpected adverse toxicities. Phase III combination trials of Ra-223 with novel oral hormonal agents are ongoing to further evaluate radiographic progression and overall survival benefit. PMID- 29196209 TI - Pathologic Outcomes of Gleason 6 Favorable Intermediate-Risk Prostate Cancer Treated With Radical Prostatectomy: Implications for Active Surveillance. AB - BACKGROUND: The safety of active surveillance (AS) for Gleason 6 favorable intermediate-risk (FIR) prostate cancer is unknown. To provide guidance, we examined the incidence and predictors of upgrading or upstaging for Gleason 6 FIR patients treated with radical prostatectomy. PATIENTS AND METHODS: We identified 2807 men in the National Cancer Database diagnosed from 2010 to 2012 with Gleason 6 FIR disease (<50% positive biopsy cores [PBC] with either prostate-specific antigen [PSA] of 10-20 ng/mL or cT2b-T2c disease) treated with radical prostatectomy. Logistic regression was used to identify predictors of upgrading (Gleason 3+4 with tertiary Gleason 5 or Gleason >=4+3) or upstaging (pT3-4/N1). RESULTS: Fifty-seven percent of the cohort had PSA of 10 to 20 ng/mL; 25.5% patients with PSA of 10 to 20 ng/mL and 12.4% with cT2b to T2c disease were upgraded or upstaged. In multivariable analysis, predictors of upgrading or upstaging included increasing age (P = .026), PSA (P = .001), and percent PBC (P < .001), and black race versus white (P = .035) for patients with PSA of 10 to 20 ng/mL and increasing PSA (P = .001) and percent PBC (P < .001) for patients with cT2b to T2c disease. Men with PSA of 15.0 to 20.0 ng/mL or 37.5% to 49.9% PBC with PSA of 10 to 20 ng/mL had >30% risk of upgrading or upstaging, whereas cT2b to T2c patients with <12.5% PBC or PSA <5.0 ng/mL had <10% risk. CONCLUSION: We found that Gleason 6 FIR patients with cT2b to T2c tumors had a low risk of harboring higher grade or stage disease and would be reasonable AS candidates, whereas patients with PSA of 10 to 20 ng/mL had a high risk and might generally be poor AS candidates.

PMID- 29196210 TI - Quantification of M13 and T7 bacteriophages by TaqMan and SYBR green qPCR. AB - TaqMan and SYBR Green quantitative PCR (qPCR) methods were developed as DNA-based approaches to reproducibly enumerate M13 and T7 phages from phage display selection experiments individually and simultaneously. The genome copies of M13 and T7 phages were quantified by TaqMan or SYBR Green qPCR referenced against M13 and T7 DNA standard curves of known concentrations. TaqMan qPCR was capable of quantifying M13 and T7 phage DNA simultaneously with a detection range of 2.75*101-2.75*108genome copies(gc)/MUL and 2.66*101-2.66*108 genome copies(gc)/MUL respectively. TaqMan qPCR demonstrated an efficient amplification efficiency (Es) of 0.97 and 0.90 for M13 and T7 phage DNA, respectively. SYBR Green qPCR was ten-fold more sensitive than TaqMan qPCR, able to quantify 2.75 2.75*107gc/MUL and 2.66*101-2.66*107gc/MUL of M13 and T7 phage DNA, with an amplification efficiency Es of 1.06 and 0.78, respectively. Due to its superior sensitivity, SYBR Green qPCR was used to enumerate M13 and T7 phage display clones selected against a cell line, and quantified titers demonstrated accuracy comparable to titers from traditional double-layer plaque assay. Compared to enzyme linked immunosorbent assay, both qPCR methods exhibited increased detection sensitivity and reproducibility. These qPCR methods are reproducible, sensitive, and time-saving to determine their titers and to quantify a large number of phage samples individually or simultaneously, thus avoiding the need for time-intensive double-layer plaque assay. These findings highlight the attractiveness of qPCR for phage enumeration for applications ranging from selection to next-generation sequencing (NGS). PMID- 29196212 TI - Axl activation attenuates neuroinflammation by inhibiting the TLR/TRAF/NF-kappaB pathway after MCAO in rats. AB - BACKGROUND AND PURPOSE: Ischemic stroke activates Toll-like receptors (TLRs), triggering rapid inflammatory cytokine production. Axl signaling has multiple roles, including regulating cytokine secretion, clearing apoptotic cells, and maintaining cell survival, however, its role in inflammation after ischemic stroke has not been examined. We hypothesized that activation of Axl by recombinant Growth-arrest-specific protein 6 (rGas6) attenuates neuroinflammation by inhibiting the TLR/TRAF/NF-kappaB pathway after middle cerebral artery occlusion (MCAO) in rats. METH: Sprague-Dawley rats were subjected to 2h of MCAO. One hour after reperfusion, the rats were given an intranasal injection of rGas6, vehicle, or R428 (Axl receptor inhibitor). Neurological scores, infarct volumes, immunofluorescence staining, Morris Water Maze, rotarod test and histology alterations were analyzed. The expressions of proinflammatory cytokines, including IL-1beta, IL-6, TNF-alpha, and Gas6, Axl, STAT1, SOCS1, SOCS3 and the TLR/TRAF/NF-kappaB pathway were quantified using Western blot. RESULTS: Endogenous expressions of Gas6 and Axl decreased significantly by 24h after MCAO. rGas6 reduced brain infarction and improved neurologic deficits scores, and increased expression of Axl and decreased the expressions of TRAF3, TRAF6 and inflammatory factors IL-1beta, IL-6, and TNF-alpha. Four weeks after MCAO, rGas6 improved long-term neurological behavior and memory. Inhibition of the Axl/TLR/TRAF/NF-kappaB pathway reversed the brain protection by rGas6. CONCLUSION: rGas6 reduced the neurological deficits by inhibiting neuroinflammation via the TLR/TRAF/NF-kappaB signaling pathway. rGas6 can be used as potential treatment to ischemic stroke. PMID- 29196213 TI - Ifngr1 and Stat1 mediated canonical Ifn-gamma signaling drives nigrostriatal degeneration. AB - Brain expression of AAV-Ifn-gamma leads to reactive gliosis, nigrostriatal degeneration and midbrain calcification in wild type mice. This mouse model phenocopies idiopathic basal ganglia calcification which is associated with Parkinsonian symptoms. To understand how the nigro-striatal pathway is selectively vulnerable to Ifn-gamma, we determined if the phenotype is driven by canonical signaling intermediates, Ifngr1 and Stat1. Using focused bioinformatic analysis and rotarod testing, we show that neuroinflammation and motor abnormalities precede the appearance of midbrain neuropathologies in the brains of Ifn-gamma mouse model. To test whether canonical Ifn-gamma signaling is a key driver of progressive nigrostriatal degeneration, we overexpressed Ifn-gamma in the brains of Ifngr1-/- and Stat1-/- mice. Expression of Ifn-gamma in Ifngr1-/- mice did not result in any neuroinflammation, midbrain calcinosis or nigrostriatal degenerative pathology. Interestingly, in Stat1-/- mice, Ifn-gamma expression resulted in gliosis without recapitulating the neurodegenerative phenotype. Overall, our data shows that canonical Ifn-gamma signaling triggers midbrain calcinosis and nigrostriatal neurodegeneration, providing mechanistic insights into cytokine-driven selective neuronal vulnerability. Our study establishes the broader relevance of inflammatory signaling in neurodegenerative diseases and can potentially identify novel immunological targets for Parkinsonian syndromes. PMID- 29196215 TI - Critical role for Annexin A7 in secondary brain injury mediated by its phosphorylation after experimental intracerebral hemorrhage in rats. AB - Glutamate excitotoxicity has been implicated in intracerebral hemorrhage (ICH) induced secondary brain injury (SBI). Synaptosome associated protein 23 (SNAP23) and SNAP25 are respectively participate in presynaptic glutamate release and postsynaptic glutamate receptor (NMDA receptor) trafficking, both of which are essential for glutamate-mediated excitatory toxicity. SNAP23 and SNAP25 exhibit high homology and SNAP23 has been shown to interact with Annexin A7 (ANXA7). This study was to examine the role of ANXA7 in ICH-induced neuronal damage. A collagenase ICH model was performed in adult male Sprague Dawley rats. First, a possible relationship between ANXA7 and ICH pathology was confirmed by an increase in the protein and mRNA level of ANXA7 in the brain tissue around hematoma of ICH rats and the rescue effects of ANXA7 knockdown in vivo on neuronal death, blood-brain barrier damage, brain edema, neurobehavioral deficient, and inflammatory response. In addition, the rescue effect of ANXA7 knockdown on neurobehavioral deficient was also verified in rat autologous blood injection ICH model. Second, we found that ICH significantly increased the phosphorylation ratio of ANXA7 at the threonine residues mainly in neurons. Finally, based on site-specific mutagenesis, we identified that ANXA7 phosphorylation at threonine 286 is required for its interaction with SNAP25 at presynaptic axon terminal and SNAP23 at postsynaptic axon terminal. Collectively, our findings suggest that ANXA7 contributed to SBI at least partially through regulating glutamate toxicity after ICH. Selective inhibition of ANXA7 phosphorylation may be a novel approach to ameliorate ICH-induced SBI. PMID- 29196214 TI - The lysosomal enzyme alpha-Galactosidase A is deficient in Parkinson's disease brain in association with the pathologic accumulation of alpha-synuclein. AB - The aberrant accumulation of alpha-synuclein (alpha-syn) is believed to contribute to the onset and pathogenesis of Parkinson's disease (PD). The autophagy-lysosome pathway (ALP) is responsible for the high capacity clearance of alpha-syn. ALP dysfunction is documented in PD and pre-clinical evidence suggests that inhibiting the ALP promotes the pathological accumulation of alpha syn. We previously identified the pathological accumulation of alpha-syn in the brains of mice deficient for the soluble lysosomal enzyme alpha-Galactosidase A (alpha-Gal A), a member of the glycosphingolipid metabolism pathway. In the present study, we quantified alpha-Gal A activity and levels of its glycosphingolipid metabolites in postmortem temporal cortex specimens from control individuals and in PD individuals staged with respect to alpha-syn containing Lewy body pathology. In late-state PD temporal cortex we observed significant decreases in alpha-Gal A activity and the 46kDa "active" species of alpha-Gal A as determined respectively by fluorometric activity assay and western blot analysis. These decreases in alpha-Gal A activity/levels correlated significantly with increased alpha-syn phosphorylated at serine 129 (p129S-alpha syn) that was maximal in late-stage PD temporal cortex. Mass spectrometric analysis of 29 different isoforms of globotriaosylceramide (Gb3), a substrate of alpha-Gal A indicated no significant differences with respect to different stages of PD temporal cortex. However, significant correlations were observed between increased levels of several Gb3 isoforms and with decreased alpha-Gal A activity and/or increased p129S-alpha-syn. Deacylated Gb3 (globotriaosylsphingosine or lyso-Gb3) was also analyzed in PD brain tissue but was below the limit of detection of 20pmol/g. Analysis of other lysosomal enzymes revealed a significant decrease in activity for the lysosomal aspartic acid protease cathepsin D but not for glucocerebrosidase (GCase) or cathepsin B in late-stage PD temporal cortex. However, a significant correlation was observed between decreasing GCase activity and increasing p129S-alpha-syn. Together our findings indicate alpha-Gal A deficiency in late-stage PD brain that correlates significantly with the pathological accumulation of alpha-syn, and further suggest the potential for alpha-Gal A and its glycosphingolipid substrates as putative biomarkers for PD. PMID- 29196217 TI - Huntington's disease leads to decrease of GABA-A tonic subunits in the D2 neostriatal pathway and their relocalization into the synaptic cleft. AB - GABA is a widely distributed inhibitory neurotransmitter. GABA-A receptors are hetero-pentameric channels assembled in multiple combinations from 19 available subunits; this diversity mediates phasic and tonic inhibitory synaptic potentials. Whereas GABA-A phasic receptors are located within the synaptic cleft, GABA-A tonic receptors are found peri- or extra-synaptically, where they are activated by diffusion of synaptic GABA release. In the neostriatum, GABA-A tonic subunits are present in the D2 medium-size spiny neurons. Since early impairment of these neurons is observed in Huntington's disease, we determined the ultrastructural localization of GABA-A-alpha5, -beta3, -delta, -rho2 and, for the first time, of GABA-A-rho3 subunits, in the D2 pathway of the YAC128 murine model of Huntington's disease at various stages of disease progression. We report mislocalization of all five subunits from peri- and extra-synaptic spaces into the synaptic clefts of YAC128 mice, present in diseased mice as early as 6 months old. The synaptic localization of GABA-A tonic receptors correlated with increased sensitivity to pharmacologic antagonists during extracellular electrophysiological recordings in neostriatal slices. Finally, the association of GABA-A tonic receptors with the D2 pathway in 6-month-old mice was largely lost at 12 months of age. PMID- 29196216 TI - A third copy of the Down syndrome cell adhesion molecule (Dscam) causes synaptic and locomotor dysfunction in Drosophila. AB - Down syndrome (DS) is caused by triplication of chromosome 21 (HSA21). It is characterised by intellectual disability and impaired motor coordination that arise from changes in brain volume, structure and function. However, the contribution of each HSA21 gene to these various phenotypes and to the causal alterations in neuronal and synaptic structure and function are largely unknown. Here we have investigated the effect of overexpression of the HSA21 gene DSCAM (Down syndrome cell adhesion molecule), on glutamatergic synaptic transmission and motor coordination, using Drosophila expressing three copies of Dscam1. Electrophysiological recordings of miniature and evoked excitatory junction potentials at the glutamatergic neuromuscular junction of Drosophila larvae showed that the extra copy of Dscam1 changed the properties of spontaneous and electrically-evoked transmitter release and strengthened short-term synaptic depression during high-frequency firing of the motor nerve. Behavioural analyses uncovered impaired locomotor coordination despite preserved gross motor function. This work identifies DSCAM as a candidate causative gene in DS that is sufficient to modify synaptic transmission and synaptic plasticity and cause a DS behavioural phenotype. PMID- 29196219 TI - Diet-induced insulin resistance state disturbs brain clock processes and alters tuning of clock outputs in the Sand rat, Psammomys obesus. AB - Reciprocal interactions closely connect energy metabolism with circadian rhythmicity. Altered clockwork and circadian desynchronization are often linked with impaired energy regulation. Conversely, metabolic disturbances have been associated with altered autonomic and hormonal rhythms. The effects of high energy (HE) diet on the master clock in the suprachiasmatic nuclei (SCN) remain unclear.This question was addressed in the Sand rat (Psammomys obesus), a non insulin-dependent diabetes mellitus (NIDDM) animal model. The aim of this work was to determine whether enriched diet in Psammomys affects locomotor activity rhythm, as well as daily oscillations in the master clock of the SCN and in an extra-SCN brain oscillator, the piriform cortex. Sand rats were fed during 3 months with either low or HE diet. Vasoactive intestinal peptide (VIP), vasopressin (AVP) and CLOCK protein cycling were studied by immunohistochemistry and running wheel protocol was used for behavioral analysis. High energy feeding dietary triggered hyperinsulinemia, impaired insulin/glucose ratio and disruption in pancreatic hormonal rhythms. Circadian disturbances in hyper-insulinemic animals include a lengthened rest/activity rhythm in constant darkness, as well as disappearance of daily rhythmicity of VIP, AVP and the circadian transcription factor CLOCK within the suprachiasmatic clock. In addition, daily rhythmicity of VIP and CLOCK was abolished by HE diet in a secondary brain oscillator, the piriform cortex. Our findings highlight a major impact of diabetogenic diet on central and peripheral rhythmicity. The Psammomys model will be instrumental to better understand the functional links between circadian clocks, glucose intolerance and insulin resistance state. PMID- 29196220 TI - New chalcone compound as a promising antileishmanial drug for an old neglected disease: Biological evaluation using radiolabelled biodistribution. AB - OBJECTIVES: Treatment of leishmaniasis remains a challenge, especially due to the need for multiple painful injections, the toxicity of current drugs against the disease, their lack of efficacy and, lately, drug resistance. The aim of this study was to demonstrate the biological behaviour of 3-nitro-2'-hydroxy-4',6' dimethoxychalcone (CH8) in a murine model of cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL). METHODS: To evaluate its biological behaviour, compound CH8 was radiolabelled with technetium-99m (99mTc) using the direct reaction. Groups of animals infected with ether Leishmania infantum (as a model for VL) or Leishmania amazonensis (as a model for CL) were administered CH8-99mTc orally or subcutaneously, respectively, and its biodistribution was evaluated. RESULTS: Oral administration of CH8-99mTc resulted in poor absorption. However, the absorbed drug was expressively taken up in the blood and liver, the main organ infected in VL. CH8-99mTc administered by the subcutaneous route showed a poor distribution and significant uptake in the left ear, suggesting a local effect in the skin. In addition, the VL and CL infection models did not considerably alter the biodistribution profile by the oral and subcutaneous routes, respectively. CONCLUSION: These results suggest that CH8 is a promising candidate for oral treatment of VL and for intralesional treatment of CL, showing a prominent local effect. PMID- 29196218 TI - Stress-induced hippocampus Npas4 mRNA expression relates to specific psychophysiological patterns of stress response. AB - Neuronal Per-Arnt-Sim (PAS) domain protein 4 (Npas4) is a key protein that intervenes in GABA synapse scaling and neurotrophicity enhancing. Since GABA and neurotrophicity are implicated in stress response and Npas4-deficient rodents exhibit behavioral alterations, an investigation was designed in rats to verify whether stress-induced spontaneous hippocampus Npas4 mRNA expression would be associated with specific patterns of stress response. The rats were exposed to one of three stressor levels: no stress (CTL, n = 15), exposure to a footshock apparatus (Sham, S, n = 40) and footshock (F, n = 80). After stress exposure the S and F rats were tested in an activity cage, and subsequently in an elevated plus maze (EPM), just prior to the sacrifice. Using cluster analysis, the animals already assigned to a stress level were also distributed into 2 subgroups depending on their Npas4 mRNA levels. The low (L) and high (H) Npas4 expression subgroups were identified in the S and F groups, the CTL group being independent of the Npas4 levels. The Npas4 effect was studied through the interaction between stress (S and F) and Npas4 level (L and H). The biological stress response was similar in H and L rats, except blood corticosterone that was slightly lower in the H rats. The H rats were more active in the actimetry cage and presented higher levels of exploration in the EPM. They also exhibited higher hippocampus activation, as assessed by the c-fos, Egr1 and Arc mRNA levels. Therefore high Npas4 expression favors stress management.

AB - We examined whether exposure to mild hyperbaric oxygen inhibits the decrease of dopaminergic neurons in the substantia nigra of a neurotoxic animal model with Parkinson's disease. Mice injected with 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine hydrochloride and probenecid twice a week were divided into two groups: mice with mild hyperbaric oxygen and those without. The mice with mild hyperbaric oxygen were exposed to 1317hPa with 45% oxygen for 3h, three times a week. The decrease in dopaminergic neurons of mice with Parkinson's disease was inhibited by 11 weeks of exposure to mild hyperbaric oxygen. We conclude that exposure to mild hyperbaric oxygen is effective in preventing the progression of Parkinson's disease.

AB - PURPOSE: To investigate the possible relationships between sigmoid diverticula, the volume of the left lateral segment of the liver and sigmoid colon volvulus. MATERIAL AND METHODS: The presence of sigmoid diverticula was analyzed in 36 patients (24 men, 12 women; mean age, 70.77+/-19.86 [SD] years) with sigmoid volvulus (group 1). The volumes of left lateral segment of the liver (i.e., segments 2 and 3 and further referred to as liver 1), liver 2 (i.e., segments 1, 4, 5, 6, 7 and 8), total liver volume and liver volume ratio (LVR) (i.e., [liver 1/liver 2]*100) were calculated from abdominal CT performed distantly from the acute episode of sigmoid volvulus. Results of volumetric measurements in group 1 were compared with those of two groups of age and gender-matched control patients without hepatopathy: one patient group with sigmoid diverticula (group 2) and one group without sigmoid diverticula (group 3). RESULTS: No patients with sigmoid volvulus had diverticulum. Liver 1 volume was lower in group 1 (193.8cm3) than in group 2 (273.75cm3) (P=0.0003). Mean LVR was greater in group 2 (24.18%) than in group 1 (14.46%) (P=1*10-7) and group 3 (18.36%) (P=0.003). Mean LVR was greater in group 3 than in group 1 (P=0.01). No significant differences in liver 2 volume and total liver volumes were found between the 3 groups. CONCLUSION: Elasticity of colon wall associated with relative hypotrophy of left lateral segment of the liver are significantly associated with sigmoid volvulus. Further studies are needed to elucidate the pathophysiological mechanisms behind this association.

AB - Activating mutations in the kinase domain of epidermal growth factor receptor (EGFR) leads to the constitutively active kinase, improves the EGFR stability and promotes malignant transformation in lung adenocarcinoma. Despite the clinical significance, the mechanism by which the increased kinase activity stabilizes the receptor is not completely understood. Using SILAC phosphoproteomic approach, we identify that Mig6 is highly phosphorylated at S256 in EGFR mutants (19del and L858R). Loss of Mig6 contributes to the efficient degradation of EGFR wildtype and mutants in lung cancer cells. Mig6 regulates the recruitment of c-Cbl to EGFR as the ablation of Mig6 enables efficient ubiquitination of the EGFR mutants through elevated recruitment of c-Cbl. We show that the cells with activating mutants of EGFR inactivate Mig6 through phosphorylation at S256. Inactivated Mig6 causes inefficient ubiquitination of EGFR, leading to defective degradation of the receptor thus contributing to the increased stability of the receptor. Taken together, we show a novel function of Mig6 in regulating the ubiquitination of EGFR. PMID- 29196225 TI - Hip prostheses in young adults. Surface prostheses and short-stem prostheses. AB - The poor results obtained in young patients when using a conventional prosthesis led to the resurgence of hip resurfacing to find less invasive implants for the bone. Young patients present a demand for additional activity, which makes them a serious challenge for the survival of implants. In addition, new information technologies contribute decisively to the preference for non-cemented prostheses. Maintaining quality of life, preserving the bone and soft tissues, as well as achieving a very stable implant, are the goals of every hip orthopaedic surgeon for these patients. The results in research point to the use of smaller prostheses, which use the metaphyseal zone more and less the diaphyseal zone, and hence the large number of the abovementioned short stem prostheses. Both models are principally indicated in the young adult. Their revision should be a more simple operation, but this is only true for hip resurfacing, not for short stems. PMID- 29196226 TI - Clinical assessment of patients with isolated hip fractures associated with an upper limb fracture. AB - INTRODUCTION: Some patients with a hip fracture also present a concomitant upper limb fracture. We want to know whether these patients have a worse functional level and whether they have any differences in various clinical parameters compared with patients with an isolated hip fracture. MATERIAL AND METHODS: We retrospectively reviewed 1061 discharge reports from the Orthogeriatrics Unit. We collected information on several clinical parameters of the fractures. Subsequently, we performed a statistical analysis of the data by comparing the associated fracture group with the isolated fracture group. RESULTS: We detected 44 patients with associated upper limb fracture, 90.9% were women (40) and the average age was 84.45years. Eighty-one point eight percent of the upper limb fractures were distal radius or proximal humerus. Pertrochanteric fractures were the most common (none of them were subtrochanteric fractures). Surgical delay was 2.60days and the average hospital stay was 12.30days. Sixty-four point three percent were nail surgery and 31% arthroplasty. The mean Barthel index score was 84.88 (P=.021). Fifty-two point 5 percent of the patients in the study group were referred to a functional support unit (P=.03). The in-hospital mortality rate was 4.2%, with no differences between groups. CONCLUSIONS: Patients with an associated fracture have a higher previous functional capacity and they are more independent. Nevertheless, after the fracture they need more help from the healthcare system for optimal functional recovery. PMID- 29196227 TI - Scaphoid Fractures treated with a volar percutaneous approach. Analysis and results in 92 cases. AB - OBJECTIVE: Herbert type B1 and B2 scaphoid fractures can be treated by orthopaedic treatment or surgery. The aim of this study is to analyse results and complications of scaphoid waist fractures treated using the percutaneous volar approach. MATERIAL AND METHOD: We present a retrospective study of 92 patients, treated in our institution from 2006 to 2016 using a volar percutaneous fixation. Mean Follow-up was 16 months (range 12-48). Injuries were classified using Hebert's classification, including B1 and B2 fracture types; the other fracture types following this classification system were excluded. Politrauma patients, dorsal approach, fractures associated with distal radius injuries, patients treated using another surgical technique and patients with non follow-up were also excluded. Functional results were evaluated using the DASH questionnaire. Consolidation was established as the presence of bony bridges crossing the fracture site on x-rays, associated with absence of pain. RESULTS: The average time to fracture healing was 6.6 weeks (range 5-11). After 12 months of follow up, the average wrist range of motion was 70 degrees of extension (range 58-75) and 70 degrees of flexion (range 62-80). Regarding functional evaluation, the average DASH questionnaire score was 42. The most frequent complication was non union in 4 cases (4.44%). Average surgical time was 25min. CONCLUSIONS: Volar percutaneous fixation is a simple and quick technique for a specialist surgeon, characterised by low morbidity and complication rates compared to ORIF and orthopaedic treatment, which accelerates the patient's functional recovery. PMID- 29196228 TI - Factors related to skeletal relapse in the two-jaw surgery treatment of mandibular prognathism. AB - This study identified factors contributing to skeletal relapse in the two-jaw surgery treatment of mandibular prognathism. A set of three standardized lateral cephalograms (T1: before surgery, T2: immediately after surgery, T3: final follow up after surgery) were obtained from 35 patients. The surgical changes were defined as follows: postsurgical immediate change (T2-T1), postoperative stability (T3-T2) and the final surgical change (T3-T1). The occlusal plane and gonial angles were also measured. Relapse was defined as the reverse movements of the menton point (Me) and point A, with the null hypothesis stating that Me and point A do not significantly change at the postoperative stability (T3-T2). A paired t test and Pearson's correlation were used for statistical analysis. The immediate postoperative changes (T2-T1) in Me and point A were significant, and were measured to be 8.5mm backward and 3.0mm forward, respectively. Additionally, the occlusal plane and gonial angles significantly increased by 2 degrees and decreased by 2 degrees , respectively. The final postoperative changes (T3-T1) in Me and point A were also significant, and were measured to be 5.2mm backward and 2.5 forward, respectively; the occlusal plane and gonial angles also increased nonsignificantly by 0.6 degrees and 0.7 degrees , respectively. Upon investigating postoperative stability (T3-T2), Me was measured to be significantly 3.3mm forward and 1.4mm upward, whereas point A was measured to be nonsignificantly 0.5mm backward and 0.9mm upward. Therefore, the null hypothesis was rejected. Pearson's correlation showed that horizontal Me (T3-T2) and point A (T3-T2) were significantly correlated with the amounts of setback Me (T2-T1) and advancement A (T2-T1), respectively. In conclusion, skeletal relapses are significantly correlated with the amounts of mandibular setback and maxillary advancement. PMID- 29196229 TI - Chin wing: Technical note. AB - The chin may be concerned by morphological abnormalities in its various dimensions. Classical genioplasty techniques can be used to correct these but have some disadvantages. The "chin wing", described by Triaca, is a technique of genioplasty extended to the mandibular angles, considering the mandibular basilar border as an anatomical unit, thus achieving a better harmonious functional and aesthetic result. The preoperative assessment included a mandibular Cone Beam to evaluate the position of the inferior alveolar nerve. The procedure was performed under general anesthesia. The periosteal dissection was limited to the osteotomy area and mental nerves were protected. The osteotomy observed a modification of its orientation in front of the mental foramen to become parallel to the basilar border, which was interrupted at the level of the mandibular angle. The spaces created were filled with bone grafts and maintained by a symphysary plate. Chin wing genioplasty both improves the function and aesthetic of the face because it considers the mandibular basilar border as an entire anatomical unit. It can be performed independently of any procedure to modify the bone bases. Nowadays, chin wing remains a challenging technique hardly performed. PMID- 29196230 TI - Functional anatomy and pathophysiologic principles in mitral regurgitation: Non invasive assessment. AB - Mitral regurgitation (MR) is the most prevalent cause of valvular heart disease (VHD) in western countries. In the Euro Heart Survey on VHD, MR was the second most common heart VHD requiring surgery. It is also the most common form of VHD in community and population-based studies from the United States. The categorization of MR based on causes and mechanisms is a major determinant of clinical outcome, of possible therapies for the MR and of the effectiveness of these therapies. Surgical mitral valve (MV) repair has been shown to improve survival in patients with severe primary MR compared with MV replacement. In addition, new percutaneous repair and replacement procedures have been recently developed. Hence, accurate understanding of the functional anatomy of the MV and the pathophysiologic principles underlying MR is needed to appropriately target valve lesions. Recent advances in cardiac imaging have allowed to deeply strengthen the knowledge of the function of the MV. The present review aims at describing the functional anatomy and pathophysiology of MR through different cardiac imaging modalities. PMID- 29196231 TI - Metabolically healthy obese and unhealthy normal weight in Iranian adult population: Prevalence and the associated factors. AB - AIMS: The objective of this study was to determine the prevalence and the associated factors of metabolically unhealthy in normal-weight and metabolically healthy in obese. METHODS: We analyzed the data of a representative sample of 986 participants recruited among adult population of north of Iran. Data were collected regarding demographic characteristics, lifestyle, body mass index, abdominal obesity measures, blood pressure, and lipid profiles. The participants were classified as metabolically healthy obese (MHO) and metabolically unhealthy normal-weight (MUNW). Metabolically unhealthy was defined as the presence of >=2 non-obese components of metabolic syndrome based on ATP III criteria. RESULTS: The prevalence rate of MUNW and MHO accounted for 17.2% and 15.1% respectively. Mean age of participants with metabolically unhealthy was significantly greater than metabolically healthy in both normal weight and overweight/obese (P=0.001). The results of multiple logistic regression analysis showed in normal-weight individuals, a significant association of MUNW was found with age group of 50-59 years(OR=3.83, 95%CI: 1.71-8.57) and 60-70 years by OR=4.74(95%CI:1.79-12.54) as compared with age group of 20-29 years. It was also associated with current smoking. While metabolically healthy state in overweight/obese was inversely associated with age 50-59 years by OR=0.26 (95%CI:0.13-0.54) and age 60-70 years by OR=0.15 (95%CI:0.05- 0.39) and higher WC by OR=0.47 (95%CI:0.31-0.72) but positively associated with female-sex by OR=1.74 (95%CI:1.07-2.82). CONCLUSION: Aging and smoking are significantly associated with metabolic abnormalities in normal-weight while aging, abdominal obesity negatively and female positively associated with metabolically healthy in obese. PMID- 29196232 TI - Integration of microbial biopesticides in greenhouse floriculture: The Canadian experience. AB - Historically, greenhouse floriculture has relied on synthetic insecticides to meet its pest control needs. But, growers are increasingly faced with the loss or failure of synthetic chemical pesticides, declining access to new chemistries, stricter environmental/health and safety regulations, and the need to produce plants in a manner that meets the 'sustainability' demands of a consumer driven market. In Canada, reports of thrips resistance to spinosad (SuccessTM) within 6 12 months of its registration prompted a radical change in pest management philosophy and approach. Faced with a lack of registered chemical alternatives, growers turned to biological control out of necessity. Biological control now forms the foundation for pest management programs in Canadian floriculture greenhouses. Success in a biocontrol program is rarely achieved through the use of a single agent, though. Rather, it is realized through the concurrent use of biological, cultural and other strategies within an integrated plant production system. Microbial insecticides can play a critical supporting role in biologically-based integrated pest management (IPM) programs. They have unique modes of action and are active against a range of challenging pests. As commercial microbial insecticides have come to market, research to generate efficacy data has assisted their registration in Canada, and the development and adaptation of integrated programs has promoted uptake by floriculture growers. This review documents some of the work done to integrate microbial insecticides into chrysanthemum and poinsettia production systems, outlines current use practices, and identifies opportunities to improve efficacy in Canadian floriculture crops. PMID- 29196233 TI - Microbial biopesticides for control of invertebrates: Progress from New Zealand. AB - Biopesticides are needed for control of endemic and invasive pests impacting New Zealand's primary sectors including pests that are emerging as a result of climate change and farming intensification. Products developed in New Zealand are usually based on endemic strains of microorganisms, including new species/strains with novel modes of action. For example, Invade and BioShield were developed using endemic strains of the bacterium Serratia entomophila, for use in New Zealand only. To date, most of these home-grown products have either struggled for market share or have remained in small niche markets. However, the number of products registered for use has been steadily increasing in response to consumer demand. Factors limiting past use of biopesticides in New Zealand include market size, registration costs and limited efficacy over a range of climatic zones. Many promising new agents are currently under development as biopesticides with international applications and the launch of several new start-up companies suggests a brighter future for biopesticide use in New Zealand. PMID- 29196234 TI - Quantitative proteomics analysis reveals alterations of lysine acetylation in mouse testis in response to heat shock and X-ray exposure. AB - Environmental stresses are important factors causing male infertility which attracts broad attention. Protein acetylation is a pivotal post-translational modification and modulates diverse physiological processes including spermatogenesis. In this study, we employed quantitative proteomic techniques and bioinformatics tools to analyze the alterations of acetylome profile of mouse testis after heat shock and X-irradiation. Overall, we identified 1139 lysine acetylation sites in 587 proteins in which 1020 lysine acetylation sites were quantified. The Gene Ontology analysis showed that the major acetylated protein groups were involved in generation of precursor metabolites and metabolic processes, and were localized predominantly in cytosolic and mitochondrial. Compared to the control group, 36 sites of 28 acetylated proteins have changed after heat shock, and 49 sites of 43 acetylated proteins for X-ray exposure. Some of the differentially acetylated proteins have been reported to be associated with the progression of spermatogenesis and male fertility. We observed the up regulated acetylation level change on testis specific histone 2B and heat shock protein upon heat treatment and a sharp decline of acetylation level on histone H2AX under X-ray treatment, suggesting their roles in male germ cells. Notably, the acetylation level on K279 of histone acetyltransferase (Kat7) was down regulated in both heat and X-ray treatments, indicating that K279 may be a key acetylated site and affect its functions in spermatogenesis. Our results reveal that protein acetylation might add another layer of complexity to the regulation for spermatogenesis, and further functional studies of these proteins will help us elucidate the mechanisms of abnormal spermatogenesis. PMID- 29196235 TI - Morphological features of the anterior talofibular ligament by the number of fiber bundles. AB - The aims of this study have been to clarify differences in morphological features based on the number of fiber bundles in the anterior talofibular ligament (ATFL), and to investigate the relationship between the ATFL and the calcaneofibular ligament (CFL). This study used 81 legs from 43 cadavers. The ATFL was classified according to differences in the number of fiber bundles as: Type I, with one fiber bundle; Type II-a, with two fiber bundles that were incompletely separated; Type II-b, with two fiber bundles that were completely separated; and Type III, with three fiber bundles. The morphological features measured were fiber bundle length, fiber bundle width, and fiber bundle angle. For the relationship between the ATFL and CFL, the positional relationship and attachment sites of the two ligaments were examined. Type I was present in 33%, Type II-a in 17%, Type II-b in 40%, and Type III in 10%. The morphological features of superior fiber bundles and inferior fiber bundles were significantly different within each type. Among types, there were significant differences in the morphological features of Type II-a and Type III inferior fiber bundles. In the relationship between the ATFL and CFL, there was a connection between the ATFL and CFL in all specimens. Various types were present in the positional relationship and attachment sites of the two ligaments. The results of this study suggest that, among different ligament types with two or three fiber bundles, the control function of the ankle may differ within each type and among types. PMID- 29196236 TI - Berries containing anthocyanins with enhanced methylation profiles are more effective at ameliorating high fat diet-induced metabolic damage. AB - Driven by the need for alternative whole food options to manage metabolic syndrome, multiple dietary interventions are suggested to achieve a better control of metabolic risk factors and molecular networks that regulate cellular energy metabolism. It is generally accepted that anthocyanin-rich diets are beneficial for maintaining healthy body weight, improving glucose and lipid metabolism, and determining inflammatory status of key metabolic tissues. However, anthocyanins are a structurally diverse group of phenolic compounds and their individual contributions to improving metabolic health are not clear. In this study, we show that consumption of berries containing anthocyanins with enhanced methylation profiles (malvidin and petunidin) is more effective at reducing high fat diet-induced metabolic damage in the C57BL/6 mouse model of polygenic obesity. Blueberries and Concord grapes (57% and 33% anthocyanins as malvidin, petunidin, or peonidin, respectively) improved body composition through individual significant effects on energy expenditure and increased activity. Methylated anthocyanins are also more effective at enhancing mitochondrial respiration and dissipation of the mitochondrial proton gradient (proton leak) in adipose tissue, thus counteracting mitochondrial dysfunction associated with metabolic stress. Together, these results provide direct proof of the higher protective potential of methylated anthocyanins against the metabolic consequences of chronic exposure to calorie-dense foods. PMID- 29196237 TI - Melatonin protects diabetic heart against ischemia-reperfusion injury, role of membrane receptor-dependent cGMP-PKG activation. AB - It has been demonstrated that the anti-oxidative and cardioprotective effects of melatonin are, at least in part, mediated by its membrane receptors. However, the direct downstream signaling remains unknown. We previously found that melatonin ameliorated myocardial ischemia-reperfusion (MI/R) injury in diabetic animals, although the underlying mechanisms are also incompletely understood. This study was designed to determine the role of melatonin membrane receptors in melatonin's cardioprotective actions against diabetic MI/R injury with a focus on cGMP and its downstream effector PKG. Streptozotocin-induced diabetic Sprague-Dawley rats and high-glucose medium-incubated H9c2 cardiomyoblasts were utilized to determine the effects of melatonin against MI/R injury. Melatonin treatment preserved cardiac function and reduced oxidative damage and apoptosis. Additionally, melatonin increased intracellular cGMP level, PKGIalpha expression, p-VASP/VASP ratio and further modulated myocardial Nrf-2-HO-1 and MAPK signaling. However, these effects were blunted by KT5823 (a selective inhibitor of PKG) or PKGIalpha siRNA except that intracellular cGMP level did not changed significantly. Additionally, our in vitro study showed that luzindole (a nonselective melatonin membrane receptor antagonist) or 4P-PDOT (a selective MT2 receptor antagonist) not only blocked the cytoprotective effect of melatonin, but also attenuated the stimulatory effect of melatonin on cGMP-PKGIalpha signaling and its modulatory effect on Nrf-2-HO-1 and MAPK signaling. This study showed that melatonin ameliorated diabetic MI/R injury by modulating Nrf-2-HO-1 and MAPK signaling, thus reducing myocardial apoptosis and oxidative stress and preserving cardiac function. Importantly, melatonin membrane receptors (especially MT2 receptor) dependent cGMP-PKGIalpha signaling played a critical role in this process. PMID- 29196238 TI - TGF-beta synergizes with ML264 to block IL-1beta-induced matrix degradation mediated by Kruppel-like factor 5 in the nucleus pulposus. AB - Intervertebral disc degeneration causes low back pain.Interleukin-1beta (IL 1beta) is a well-known inflammatory mediator that is involved in disc degeneration but its molecular mechanisms on catabolic and anabolic events in nucleus pulposus (NP) cells remain unclear. Kruppel-like factor 5 (KLF5) is associated with inflammation and was previously shown to cause cartilage degradation. In this study, we revealed that KLF5 is involved in IL-1beta activated NF-kB cascade by enhancing both p65 phosphorylation and p65 acetylation. Moreover, the catabolic effect of KLF5 can be abolished by transforming growth factor-beta (TGF-beta) via promoting the proteasomal degradation of KLF5. Therefore, a KLF5 inhibitor ML264 was further proved to synergize with TGF-beta to attenuate IL-1beta-induced intervertebral disc degeneration. These results indicate the critical role of KLF5 in regulating intervertebral disc metabolism and suggest KLF5 inhibitor such as ML264 as potential compound for treatment of degenerative disc disease. PMID- 29196240 TI - The pathophysiology of human obstructive cholestasis is mimicked in cholestatic Gold Syrian hamsters. AB - Obstructive cholestasis causes liver injury via accumulation of toxic bile acids (BAs). Therapeutic options for cholestatic liver disease are limited, partially because the available murine disease models lack translational value. Profiling of time-related changes following bile duct ligation (BDL) in Gold Syrian hamsters revealed a biochemical response similar to cholestatic patients in terms of BA pool composition, alterations in hepatocyte BA transport and signaling, suppression of BA production, and adapted BA metabolism. Hamsters tolerated cholestasis well for up to 28days and progressed relatively slowly to fibrotic liver injury. Hepatocellular necrosis was absent, which coincided with preserved intrahepatic energy levels and only mild oxidative stress. The histological response to cholestasis in hamsters was similar to the changes seen in 17 patients with prolonged obstructive cholestasis caused by cholangiocarcinoma. Hamsters moreover upregulated hepatic fibroblast growth factor 15 (Fgf15) expression in response to BDL, which is a cytoprotective adaptation to cholestasis that hitherto had only been documented in cholestatic human livers. Hamster models should therefore be added to the repertoire of animal models used to study the pathophysiology of cholestatic liver disease. PMID- 29196239 TI - Insulin and branched-chain amino acid depletion during mouse preimplantation embryo culture programmes body weight gain and raised blood pressure during early postnatal life. AB - Mouse maternal low protein diet exclusively during preimplantation development (Emb-LPD) is sufficient to programme altered growth and cardiovascular dysfunction in offspring. Here, we use an in vitro model comprising preimplantation culture in medium depleted in insulin and branched-chain amino acids (BCAA), two proposed embryo programming inductive factors from Emb-LPD studies, to examine the consequences for blastocyst organisation and, after embryo transfer (ET), postnatal disease origin. Two-cell embryos were cultured to blastocyst stage in defined KSOM medium supplemented with four combinations of insulin and BCAA concentrations. Control medium contained serum insulin and uterine luminal fluid amino acid concentrations (including BCAA) found in control mothers from the maternal diet model (N-insulin+N-bcaa). Experimental medium (three groups) contained 50% reduction in insulin and/or BCAA (L-insulin+N-bcaa, N-insulin+L-bcaa, and L-insulin+N-bcaa). Lineage-specific cell numbers of resultant blastocysts were not affected by treatment. Following ET, a combined depletion of insulin and BCAA during embryo culture induced a non sex-specific increase in birth weight and weight gain during early postnatal life. Furthermore, male offspring displayed relative hypertension and female offspring reduced heart/body weight, both characteristics of Emb-LPD offspring. Combined depletion of metabolites also resulted in a strong positive correlation between body weight and glucose metabolism that was absent in the control group. Our results support the notion that composition of preimplantation culture medium can programme development and associate with disease origin affecting postnatal growth and cardiovascular phenotypes and implicate two important nutritional mediators in the inductive mechanism. Our data also have implications for human assisted reproductive treatment (ART) practice. PMID- 29196241 TI - Scleroderma skin ulcers definition, classification and treatment strategies our experience and review of the literature. AB - BACKGROUND: Skin ulcers (SU) are one of the most frequent manifestations of systemic sclerosis (SSc). SSc-SU are very painful, often persistent and recurrent; they may lead to marked impairment of patient's activities and quality of life. Despite their severe impact on the whole SSc patient's management, the proposed definition, classification criteria, and therapeutic strategies of SSc SU are still controversial. OBJECTIVE: The present study aimed to elaborate a comprehensive proposal of definition, classification, and therapeutic strategy of SSc-SU on the basis of our long-term single center experience along with a careful revision of the world literature on the same topic. METHODS: A series of 282 SSc patients (254 females and 28 males; 84% with limited and 16% diffuse cutaneous SSc; mean age of 51.5+/-13.9SD at SSc onset; mean follow-up 5.8+/ 4.6SDyears) enrolled during the last decade at our Rheumatology Unit were retrospectively evaluated with specific attention to SSc-SU. The SSc-SU were classified in 5 subtypes according to prominent pathogenetic mechanism(s) and localization, namely 1. digital ulcers (DU) of the hands or feet, 2. SU on bony prominence, 3. SU on calcinosis, 4. SU of lower limbs, and 5. DU presenting with gangrene. This latter is a very harmful evolution of both DU of the hands and feet needing a differential diagnosis with critical limb ischemia. RESULTS: During the follow up period, one or more episodes of SSc-SU were recorded in over half patients (156/282, 55%); skin lesions were often recurrent and difficult-to heal because of local complications, mainly infections (67.3%), in some cases associated to osteomyelitis (19.2%), gangrene (16%), and/or amputation (11.5%). SSc-SU were significantly associated with lower patients' mean age at the disease onset (p=0.024), male gender (p=0.03), diffuse cutaneous subset (p=0.015), calcinosis (p=0.002), telangiectasia (p=0.008), melanodermia (p<0.001), abnormal PAPs (p=0.036), and/or altered inflammation reactant (CRP, p=0.001). Therapeutic strategy of SSc-SU included both systemic and local pharmacological treatments with particular attention to complicating infections and chronic/procedural pain, as well as a number of non-pharmacological measures. Integrated local treatments were often decisive for the SSc-SU healing; they were mainly based on the wound bed preparation principles that are summarized in the acronym TIME (necrotic Tissue, Infection/Inflammation, Moisture balance, and Epithelization). The updated review of the literature focusing on this challenging issue was analyzed in comparison with our experience. CONCLUSIONS: The recent advancement of knowledge and management strategies of SSc-SU achieved during the last years lead to the clear-cut improvement of patients' quality of life and reduced long-term disability. PMID- 29196242 TI - Imaging aspects of interstitial lung disease in patients with rheumatoid arthritis: Literature review. AB - OBJECTIVE: Interstitial lung disease (ILD) is a frequent and severe complication of rheumatoid arthritis (RA), resulting in pulmonary fibrosis (PF) and respiratory failure. METHODS: Chest computed tomography (CT-c) or high resolution CT (HRCT) is the main modality for assessment of ILD. We performed a systematic literature review on CT-c/HRCT findings in patients with ILD-RA, using the MEDLINE database for the period from 1991 to 2015. RESULTS: Findings on CT-c/HRCT attributed to ILD-RA are variable (ground glass opacities, reticular and nodular pattern, as well as a combined pattern of emphysema and PF). Correlation of CT c/HRCT findings with clinical data is inconsistent. CONCLUSIONS: ILD-RA is part of a general autoimmune inflammation and should be integrated into the decision making process for the treatment of RA. There is an unmet need to design an algorithm which will allow prediction of CT-c changes compatible with ILD-RA with a high probability. Hopefully, this will enable treating patients with ILD-RA early, with possible halting of the progression of ILD-RA toward PF. PMID- 29196243 TI - Clinical and immunological aspects of anti-peptidylarginine deiminase type 4 (anti-PAD4) autoantibodies in rheumatoid arthritis. AB - Rheumatoid arthritis (RA) is the most common rheumatic autoimmune disease worldwide, which causes progressive joint damage and can lead to functional disability. Despite prominent advances in RA diagnosis and treatment during the last 20years, there is still a need for novel biomarkers that aid in diagnosis and prognosis of this heterogeneous disease. Citrullination is a key post translational modification implicated on anti-citrullinated protein/peptide antibodies (ACPA) production in RA, catalyzed by human peptidylarginine deiminases (PADs). Among these enzymes, PAD4 has been recognized as an important player in RA pathogenesis and the enzyme itself is a target of autoantibodies (anti-PAD4) in a subgroup of RA patients. Accumulating evidence suggests that anti-PAD4 autoantibodies may be useful as a severity biomarker in RA and recent studies have also shed light on the functional significance of these autoantibodies. This review summarizes the evidence on anti-PAD4 autoantibodies in RA, and addresses its usefulness for disease diagnosis and prognosis. Novel immunological aspects of anti-PAD4 antibodies and their relevance to RA pathogenesis are also discussed. PMID- 29196244 TI - A concise review of significantly modified serological biomarkers in giant cell arteritis, as detected by different methods. AB - Giant cell arteritis (GCA) is a primary systemic vasculitis present in subjects older than 50years with involvement of large- and medium-sized arteries. Early diagnosis for GCA is essential to prevent serious complications, such as permanent vision loss and/or cerebrovascular events. Elevated inflammatory cytokines, with acute phase and other proteins dominate large- and medium-sized arteries leading to stenosis or occlusion of arterial lumen. To date, there are no reliable serological markers for monitoring GCA. The review aims to provide concise overview of published GCA studies in order to: a) identify significantly changed serological biomarkers in GCA and compare the influences of techniques for marker evaluation and b) investigate most promising markers in GCA using analyte frequency and meta-analysis. PMID- 29196245 TI - Novel potential photodynamic therapy strategy using 5-Aminolevulinic acid for ovarian clear-cell carcinoma. AB - BACKGROUND: Photodynamic therapy (PDT) is known as a minimally invasive treatment for cancer. 5-Aminolevulinic acid (ALA) is a precursor of the photosensitizing agent protoporphyrin IX (PpIX). Patients with ovarian clear-cell carcinoma (CCC) have poorer prognoses than those of patients with other histological CCC types. We evaluated the efficacy of ALA-PDT on CCC cells in vitro. METHODS: We used seven human CCC cell lines to measure the cytotoxicity of ALA-PDT. PpIX production in cancer cells was measured using a micro-plate reader. Quantitative real-time PCR was performed to assess the mRNA levels of genes involved in the accumulation of PpIX in cancer cells. Additionally, we measured the enhancement in cytotoxicity with the use of an ABCG2 inhibitor. RESULTS: We found that three cell lines were highly sensitive to ALA-PDT. In contrast, one cell line was resistant to ALA-PDT. The cytotoxicity of ALA-PDT varied among CCC cell lines. The IC50 values of ALA-PDT for the CCC cell lines had a wide range (30-882MUM). The cytotoxicity of ALA-PDT was correlated with the intracellular PpIX accumulation. The cell lines sensitive to ALA-PDT expressed PEPT1 (an ALA uptake transporter). The cell line resistant to ALA-PDT expressed ABCG2 (a PpIX export transporter). In the resistant cell line, a combination treatment with both ALA and an ABCG2 inhibitor resulted in the promotion of cytotoxic sensitivity. CONCLUSION: The present study revealed the efficacy of ALA-PDT against CCC with chemoresistance in vitro.

AB - Antimicrobial photodynamic therapy (aPDT) could constitute an alternative therapy to antibiotics especially against superficial infections caused by bacteria involved in multidrug resistance processes. The aim of this study is to compare the efficacy of aPDT using the photosensitizer rose bengal (RB), combined or uncombined with gentamicin (GN), against Staphylococcus aureus. Different concentrations of RB (ranging from 0.03 to 64 MUg/ml) were added to S. aureus in water suspensions or forming biofilms in the absence or presence of GN (1-40 MUg/ml) and the samples were irradiated (18 or 37 J/cm2). The number of viable bacteria was quantified by counting colony-forming units. RB-aPDT shows significant photoactivity. The combination of GN and RB-aPDT exerts a synergistic bactericidal effect against planktonic S. aureus. On the other hand, a synergistic effect is observed only when the maximum concentration tested of RB and GN was used in biofilm. According to these result the use of RB-aPDT alone or in combination with GN could be implemented against S. aureus. PMID- 29196247 TI - Early and Late Posttraumatic Epilepsy in the Setting of Traumatic Brain Injury: A Meta-analysis and Review of Antiepileptic Management. AB - BACKGROUND: Moderate to severe traumatic brain injury confers increased risk of posttraumatic seizures (PTSs). Early PTSs are diagnosed when seizures develop within 7 days after injury, whereas seizures diagnosed as late PTSs occur later. Patients have been treated with phenytoin (PHT) to prevent early PTSs and more recently with levetiracetam (LEV). Various regimens have been tried in patients to prevent late PTSs with variable success. We assessed and compared effectiveness of these drugs on early and late PTS prevention. METHODS: A literature search revealed 120 articles. Data were included if the same factors were compared across studies with identical treatment arms. Random effects models were used for meta-analysis to combine data into an overriding odds ratio (OR) comparing PTS incidence. For early PTSs, PHT was compared with placebo and LEV with PHT. For late PTSs, each drug was compared with placebo. RESULTS: Sixteen studies were included. PHT was associated with decreased odds of early seizures relative to placebo (OR = 0.34, 95% confidence interval [CI] 0.19-0.62). There was no difference in early seizure incidence between LEV and PHT (OR = 0.83, 95% CI 0.33-2.1). Neither LEV (OR = 0.69, 95% CI 0.24-1.96) nor PHT (OR = 0.4, 95% CI 0.1-1.6) was associated with fewer late PTSs than placebo. CONCLUSIONS: New literature is consistent with current guidelines supporting antiepileptic drug administration for prevention of early, but not late, PTSs. With regard to early PTS prevention, LEV and PHT are similarly efficacious, which is consistent with current guidelines. Side-effect profiles favor LEV administration over PHT. PMID- 29196248 TI - Coagulation Factor Hyperfunction After Subarachnoid Hemorrhage Induces Deep Venous Thrombosis. AB - OBJECTIVE: To explore the change of coagulation function and associated potential mechanisms and the relationship between coagulation disorders and deep venous thrombosis (DVT) after subarachnoid hemorrhage (SAH) within 3 days of onset. METHODS: A total of 150 patients with SAH within 3 days of onset and 100 healthy individuals were recruited. Thrombelastography analysis and traditional laboratory tests were performed. Tissue factor (TF), tissue factor pathway inhibitor (TFPI) and activated protein C (APC) were tested by using enzyme-linked immunoassay kits. Extremities of patients with SAH were scanned by Doppler ultrasonography. Subgroup analysis was performed in patients with SAH based on the presence or lack of DVT. RESULTS: Compared with control groups, R (an indicator of coagulation factor function in thrombelastography) was significantly decreased (4.32 +/- 0.99 minutes vs. 6.00 +/- 0.75 minutes; P < 0.001), especially in patients with DVT. TF was significantly increased (20.84 +/- 4.15 pg/mL vs. 5.24 +/- 1.86 pg/mL; P < 0.001). TFPI was decreased (50.42 +/- 5.81 ng/mL vs. 64.10 +/- 6.04 ng/mL). APC had no apparent changes. R was negatively correlated with TF (r = 0.358; P < 0.05) and positively correlated with TFPI (r = 0.325; P < 0.05) and APC (r = 0.162; P < 0.05). TF, TFPI, and APC had the same variation characteristics in the DVT subgroup compared with the no DVT subgroup. DVT was associated with R through association analysis (r = 0.369; P < 0.05). The R cutoff value for estimating the presence of DVT was 3.65 minutes. CONCLUSIONS: Coagulation factor hyperfunction may be mainly accompanied within 3 days of SAH onset and may induce DVT. This situation may be associated with TF-TFPI-APC imbalance. R = 3.65 minutes was a potential intervention point to prevent the risk of DVT in this population. PMID- 29196249 TI - Deep Brain Stimulation for Essential Tremor: A Comparison of Targets. AB - BACKGROUND: Deep brain stimulation (DBS) is an established treatment for refractory essential tremor (ET). Initially, the target of choice was the thalamic ventralis intermedius nucleus (VIM). However, the zona incerta (ZI) has been suggested as a superior target. Both targets are considered safe and effective, but a direct comparison between these targets is lacking. METHODS: We analyzed a single-center cohort of 44 patients with ET treated with DBS between 1998 and 2017, targeting the VIM and/or ZI. Patient-reported outcome on the Washington Heights-Inwood Genetic Study of Essential Tremor rating scale, adverse events, and stimulation-induced side effects were assessed. RESULTS: Patient reported outcome of ZI DBS (-2.2 +/- 1.2; 18 patients with 28 electrodes) was superior to VIM DBS (-1.2 +/- 1.4; 10 patients with 19 electrodes) (P < 0.01). There was no difference in adverse events between implantations in VIM (45%) and ZI (46%). Dysarthria stimulation-induced side effects were significantly more often reported after VIM DBS (P = 0.01), whereas visual stimulation-induced side effects occurred more often after ZI DBS (P = 0.04). CONCLUSIONS: In this study, ZI DBS was superior to VIM DBS in terms of patient-reported effectiveness. There was a comparable number of complications between both targets. This finding further supports ZI over VIM as the principal DBS target in essential tremor. PMID- 29196250 TI - The Influence of Sedation Level Guided by Bispectral Index on Therapeutic Effects for Patients with Severe Traumatic Brain Injury. AB - BACKGROUND: Sedation therapy is vital for treating severe traumatic brain injury (TBI). Yet, types of sedation assessment tools and sedation levels that are suitable for sedation treatment have not been investigated. OBJECTIVE: To investigate the influence of different sedation levels guided by the Bispectral Index (BIS) on the therapeutic effects for severe TBI. METHODS: According to inclusion, exclusion, and rejection criteria, 35 patients were prospectively included and divided into Richmond Agitation Sedation Scale (RASS), BIS(I), and BIS(II) groups. The RASS group was controlled the level of sedation to within -2 or -3, and the BIS(I) and (II) groups within the range of 40-50 and 50-60, respectively. In addition to clinical data, RASS, BIS, and intracranial pressure (ICP) values were collected. RASS and ICP variability were introduced to investigate the different of sedative control effect with or without BIS monitor, and the control effect of ICP between different sedation levels. Statistical analysis was performed to estimate the effectiveness of different sedation levels guided by BIS in sedation treatment within 72 hours. RESULTS: There were no significant differences in demographics among the 3 groups. RASS variability of the BIS(I) and (II) groups was significantly lower than that of the RASS group (P < 0.05), and in the BIS(I) group it was insignificantly lower than in the BIS(II) group. The ICP of the BIS(I) and (II) groups declined to <13.5 mm Hg significantly earlier than that of the RASS group (P < 0.05), and the difference between BIS(I) and (II) was insignificant. ICP variability of RASS group was higher than those of the BIS(I) and (II) groups (P < 0.05), and ICP variability of the BIS(I) group was significantly lower than that of the BIS(II) group (P < 0.05). Differences in days in the neurosurgery intensive care unit and outcomes among the 3 groups were insignificant. CONCLUSIONS: BIS is more reliable than RASS for maintaining a stable sedation status and ICP. Deeper sedation levels (BIS 40-50) cause ICP to decrease more quickly, with lower ICP variability. PMID- 29196251 TI - Effectiveness of Ipsilateral Stroke Prevention Between Conservative Management and Indirect Revascularization for Moyamoya Disease in a North American Cohort. AB - BACKGROUND: Few reports have compared surgical intervention with conservative treatment for moyamoya disease (MMD) in non-Asian cohorts. This study describes the effectiveness of follow-up stroke prevention by indirect revascularization relative to conservative management in a Northeast United States study population. METHOD: We retrospectively reviewed records of patients with MMD at our institution from 1990 to 2014. Baseline characteristics and follow-up results including subsequent ipsilateral strokes were collected, and compared between an indirect revascularization group and a conservatively treated group on a per hemisphere basis. RESULTS: A total of 94 patients with 184 hemispheres were included. The average age was 23.9 +/- 18.1 years, with 76.6% (n = 141) being female. Racial distribution comprised white (n = 75, 40.8%), African-American (n = 57, 31.0%), Asian (n = 30, 16.3%), and other (n = 22, 12.0%). Eighty-three hemispheres (45.1%) presented with ipsilateral stroke and 54 (29.3%) with ipsilateral TIA. Management strategies included either conservative management (51.1%) or indirect bypass (48.9%). Patients who were male (P < 0.001), on baseline antiplatelets (P = 0.043), or with speech disturbance (P = 0.002) were more likely to receive indirect revascularization. Patients with headache history were more likely to be treated conservatively (P = 0.046). History of ipsilateral stroke was borderline associated with indirect bypass (P = 0.058). During a follow-up period of 6.37 +/- 5.81 years, the annual risk of stroke for indirect revascularization group was 0.93% and 2.70% for the conservative group. Multivariate analysis found that increasing age (P = 0.029), posterior cerebral artery involvement (P = 0.040), and conservative treatment (P = 0.048) were associated with follow-up stroke. CONCLUSION: Our results suggests that indirect revascularization provides symptom relief and lower risk of stroke during follow up compared with conservative management. Indirect revascularization should be considered for symptomatic MMD patients with a low surgical risk profile in a similar patient population. PMID- 29196252 TI - Atypical and Malignant Meningiomas: Neurooncologic Management in a Brazilian cohort. AB - OBJECTIVE: To analyze the surgical and oncologic treatment of a Brazilian cohort of patients with grade II and III meningioma at a follow-up time of 15 years to get an overview of these patients' outcomes. METHODS: Cross-sectional study of 43 patients (26 women, 17 men; age range 20 to 83 years; average 57.72 +/- 14.54) operated on from 2000 to 2014 at a single institution, with the neuropathologic diagnosis of meningioma grade II (39 patients) and grade III (4 patients). RESULTS: Radiotherapy: 24 patients (55.81%) underwent radiotherapy; the time between the surgical procedure and the beginning of radiotherapy was 5 months; 7 patients with a diagnosis of AM underwent a new surgical procedure, albeit of adjuvant therapy, because of tumor recurrence, and only 3 of them underwent radiotherapy after the first resection. Mortality: in total, 19 deaths (44.18%) were identified in this sample: 15 (38.46%) with GII and 4 (100%) with GIII. The 10-year survival was expected in 35% of GII patients and 0% of GIII patients. CONCLUSION: Surgery is still the main form of treatment and the mainstay for prolonging survival. Radiotherapy is still controversial; however, we observed its positive impact on recurrence and progression-free survival. PMID- 29196253 TI - Involvement of Lypge in the formation of eye and pineal gland in zebrafish. AB - The proteins of Ly-6 (lymphocyte antigen-6) family are involved in the regulation of immunoreaction, cell migration and adhesion, and neuronal excitability. However, little is known about the function of Ly-6 proteins in embryogenesis. Herein, we identified a GPI anchored Ly-6 member named ly6 expressed in pineal gland and eye (lypge). Dynamic expression pattern of lypge was revealed by whole mount in situ hybridization. It was strikingly expressed in the pineal gland and cone photoreceptor, and its expression was regulated by orthodenticle homolog 5 (otx5) which has been shown to control the expression of many pineal genes. In addition, we demonstrated that lypge was rhythmically expressed in larvae from 4dpf on. Moreover, knockdown of lypge resulted in small head and small eye formed in zebrafish embryos. These suggest that Lypge is involved in the formation of the eye and pineal gland in early development of zebrafish. PMID- 29196254 TI - Adiponectin gene variants and decreased adiponectin plasma levels are associated with the risk of myocardial infarction in young age. AB - The aim of the study was to investigate the role of adiponectin and 5 variants of its gene in the risk of premature myocardial infarction (MI). The studied group (MI<50) consisted of 158 young patients (125 men) aged <50 with MI. The control groups consisted of 155 healthy people (97 men), aged <50 and 202 patients (130 men) aged >=50 with MI (MI>=50). There were statistically significant differences between MI<50 patients and healthy control group in the prevalence of rs17300539:G>A (AA genotype: 19.3% vs. 0%, p<0.0001) and rs72563731:C>T variants (CC genotype: 81.5% vs. 15.9%, p<0.0001) and between MI<50 and MI>=50 patients in variants: rs17300539:G>A (AA genotype: 19.3% vs. 0.5%, p<0.0001), rs72563731:C>T (CC genotype: 82.1% vs. 60.8%, p<0.0001), rs1501299:G>T (TT genotype: 6.8% vs. 14.9%, p=0.019) and rs822387:T>C (genotype CC: 1.5% vs. 0%, p=0.017). Multivariate analysis showed a significantly higher risk of MI in young CC carriers of rs72563731:C>T and in young AA carriers of rs17300539:G>A. Total and HMW adiponectin plasma levels have been significantly lower in MI<50 patients in comparison to MI>=50 patients (p=0.001 and p=0.001, respectively) and to healthy subjects (p=0.009 and p=0.01, respectively). Our study indicates the possible role of adiponectin and its genetic variants in MI in young age. PMID- 29196256 TI - Diverse responses of tanshinone biosynthesis to biotic and abiotic elicitors in hairy root cultures of Salvia miltiorrhiza and Salvia castanea Diels f. tomentosa. AB - Salvia miltiorrhiza (S. miltiorrhiza) and Salvia castanea Diels f. tomentosa (S. castanea) are both used for treatment of cardiovascular diseases. They have the same bioactive compound tanshinones, but whose contents are hugely different. This study illustrated diverse responses of tanshinone biosynthesis to yeast extract (YE) and Ag+ in hairy roots of the two species. YE enhanced both the growth and tanshinone biosynthesis of two hairy roots, and contributed more to tanshinone accumulation in S. castanea than that in S. miltiorrhiza. Genes encoding 1-deoxy-d-xylulose 5-phosphate synthase (DXS2), geranylgeranyl diphosphatesynthase (GGPPS1), copalyl diphosphate synthase (CPS1), and two cytochromes P450 (CYP76AH1 and CYP76AH3) were also more responsive to YE in S. castanea than those in S. miltiorrhiza. Accumulations of dihydrotanshinone I and tanshinone I, and most biosynthetic genes in S. miltiorrhiza were more responsive to Ag+ than those in S. castanea. Accumulations of dihydrotanshinone I and cryptotanshinone were more responsive to YE, while tanshinone IIA accumulation was more responsive to Ag+ in S. miltiorrhiza. However, accumulations of other four tanshinones and related genes in S. castanea were more responsive to YE than Ag+. This study provides foundations for studying diverse specialized metabolism between the related species. PMID- 29196255 TI - Hypermethylation of PGCP gene is associated with human bronchial epithelial cells immortalization. AB - Cell immortalization is the initial step for cancer development. To identify the differentially expressed genes regulated by DNA methylation over the course of human primary bronchial epithelial cell (HPBECs) immortalization, an immortalized HBE cell line (HBETT) was generated via introduction of an SV40 LT and a catalytic subunit of human telomerase reverse transcriptase (hTERT) into the HPBECs. Microarrays of mRNA and DNA methylation were performed to compare the transcriptomes and DNA methylomes between these two types of cells. The results from the mRNA microarray revealed many genes whose expression changed upon cell immortalization. We identified signatures including global hypomethylation, perturbation of ECM-receptor interaction, focal adhesion, and PI3K-Akt pathways associated with cell immortalization. Moreover, we revealed 155 differentiated methylation regions (DMRs) within the CpG islands (CGIs) of 42 genes and the perturbation of several key pathways that might be involved in HBE cell immortalization. Among these genes, the hypermethylation of the plasma glutamate carboxypeptidase (PGCP) gene appeared specifically in lung cancer tissues. The inhibition of PGCP expression by promoter hypermethylation was observed in both immortal HBETT cells and benzo[a]pyrene (Bap)-transformed HBE cells. In conclusion, these findings provide new insight into the epigenetic modifications that are critical in the transition and maintenance of cell immortalization. PMID- 29196257 TI - The miR-875-5p inhibits SATB2 to promote the invasion of lung cancer cells. AB - The pathogenesis of non-small cell lung cancer (NSCLC) is regulated by various miRNAs. In this study, we identified that miR-875-5pis up-regulated in NSCLC patients, and inhibited SATB Homeobox 2(SATB2) to promote proliferation and invasion of NSCLCcells.CCK-8assay revealed thatmiR-875-5p mimics promoted proliferation of NSCLC cells. Transwell assay showed that miR-875 5pmimicspromoted the invasion and migration of NSCLC cells. Luciferase assays confirmed that miR-875-5pdirectly binds to the 3'untranslated region of SATB2, and western blotting showed that miR-875-5psuppresses the expression of SATB2 at the protein level. Moreover, the inhibitors of miR-875-5pinhibit proliferation and invasion of NSCLC cell lines. The miR-875-5pwouldbe a potential therapeutic target for NSCLC treatment in the future. PMID- 29196258 TI - LW-215, a newly synthesized flavonoid, exhibits potent anti-angiogenic activity in vitro and in vivo. AB - LW-215 is a newly synthesized flavonoid, which is the derivative of wogonin. Our group has previously confirmed that wogonin has an anti-angiogenic activity, while the anti-angiogenic effect of LW-215 is unclear. In this study, we explored whether LW-215 can inhibit angiogenesis and further probed the potential molecular mechanisms. We found that LW-215 inhibited migration and tube formation in human umbilical vein endothelial cells (HUVECs) and immortalized endothelial EA.hy926 cells without a significant decrease in cell viability. Microvessels sprouting from rat aortic ring and chicken chorioallantoic membrane (CAM) model also revealed that LW-215 could suppress angiogenesis in vivo. Western blot and ELISA analysis indicated that LW-215 could prevent VEGFR2 activation though reducing VEGF autocrine other than VEGFR1. Thus, its downstream kinases, such as Akt, ERK and p38 signaling, were inhibited. Taken together, these results fully showed that LW-215 might be a promising anti-angiogenesis agent. PMID- 29196259 TI - Arabidopsis calcium-dependent protein kinase AtCPK1 plays a positive role in salt/drought-stress response. AB - The calcium-dependent protein kinases (CDPKs) play vital roles in plant response to various environmental stimuli. Here, we investigated the function of Arabidopsis AtCPK1 in response to salt and drought stress. The loss-of-function cpk1 mutant displayed hypersensitive to salt and drought stress, whereas overexpressing AtCPK1 in Arabidopsis plants significantly enhanced the resistance to salt or drought stress. The reduced or elevated tolerance of cpk1 mutant and AtCPK1-overexpressing lines was confirmed by the changes of proline, malondialdehyde (MDA) and H2O2. Real-time PCR analysis revealed that the expression of several stress-inducible genes (RD29A, COR15A, ZAT10, APX2) down regulated in cpk1 mutant and up-regulated in AtCPK1-overexpressing plants. These results are likely to indicate that AtCPK1 positively regulates salt and drought stress in Arabidopsis. PMID- 29196260 TI - Advanced glycation end products promote triple negative breast cancer cells via ERK and NF-kappaB pathway. AB - Advanced glycation end products (AGEs) are harmful compounds generated by nonspecific glycation of proteins and lipids. The accumulation of AGEs is associated with various diseases, including breast cancer. AGEs have been shown to promote a breast cancer cell line by enhancing proliferation, invasion and migration. In this study, we investigated the effect and associated mechanism of AGEs on triple negative breast cancer cells. AGEs enhanced the proliferation, tumorigenicity, invasion and migration of primary breast cancer cells. AGEs also enhanced the RNA and protein expression of matrix metalloproteinase (MMP)-9 and its gelatinase activity. Enhanced MMP-9 expression was mediated by extracellular signal regulated kinase (ERK) and nuclear factor kappa B (NF-kappaB) pathways. Moreover, inhibitors of ERK and NF-kappaB signaling attenuated the effect of AGEs on tumorigenicity, invasion and migration of primary breast cancer cells. Taken together, we suggest that AGEs directly promote primary breast cancer cells via the ERK and NF-kappaB pathway, which may lead to advanced therapeutic modalities of breast cancer. PMID- 29196261 TI - A-674563 increases chondrocyte marker expression in cultured chondrocytes by inhibiting Sox9 degradation. AB - The implantation of autologous chondrocytes is a therapeutic treatment for articular cartilage damage. However, the benefits are limited due to the expansion of chondrocytes in monolayer culture, which causes loss of chondrocytic characters. Therefore, culture conditions that enhance chondrocytic characters are needed. We screened 5822 compounds and found that A-674563 enhanced the transcription of several chondrocyte marker genes, including Col2a1, Acan and Col11a2, in mouse primary chondrocytes. Experiments using cycloheximide, MG132 and bafilomycin A1 have revealed that Sox9 is degraded through the ubiquitin proteasome pathway and that A-674563 inhibits this degradation, resulting in larger amount of Sox9 protein. RNA sequencing transcriptome analysis showed that A-674563 increases the expression of the gene that encodes ubiquitin-specific peptidase 29, which is known to induce the deubiquitination of proteins. Although the precise mechanism remains to be determined, our findings indicated that A 674563 could contribute to culture conditions that expand chondrocytes without losing chondrocytic characters. PMID- 29196262 TI - Collagen VI suppresses fibronectin-induced enteric neural crest cell migration by downregulation of focal adhesion proteins. AB - The enteric nervous system (ENS) is a network of neurons and glia that are derived from enteric neural crest cells (ENCCs) and essential for regulating peristaltic activity of the colon. ENCCs migrate along the gastrointestinal tract to form the ENS, and disruption of ENCC motility leads to ENS disorders, such as Hirschsprung's disease. Previous ENCC-transplant experiments show that ENCCs can invade into isolated mouse intestines by age E13.5, but not after E15.5. We hypothesized that altered age-specific micro-environments in the intestine are responsible for ENCC invasion/migration. Here, we compared gene expression in the intestine between at E11.5 and E15.5 and identified 1355 differentially expressed transcripts. Among these, we found that genes encoding extracellular matrix (ECM) proteins were enriched. Notably, collagen VI (ColVI) family members were upregulated in the E15.5 mouse intestine at the mRNA and protein levels, whereas fibronectin (FN) was downregulated; however, both proteins showed colocalization at E15.5. To understand the mechanisms of ColVI and FN in ENCC migration, we examined neurosphere or individual ENCC-adherence capabilities toward the ECM. ColVI suppressed FN-induced ENCC spreading/migration, whereas ColVI induced morphologically narrow ENCC spreading and weak stress-fiber formation as compared with those with FN. Additionally, in ENCCs cultured on plates containing ColVI, the expression and phosphorylation of p130Cas, a members of focal adhesion complexes, was reduced. These data indicated an inhibitory role of ColVI in ENCC migration and suggested that ColVI suppression in the intestine might represent a novel therapeutic strategy for aganglionic colonic diseases. PMID- 29196263 TI - Hypothesis: Hypoxia induces de novo synthesis of NeuGc gangliosides in humans through CMAH domain substitute. AB - Immunotherapy is a growing field in cancer research. A privileged tumor associated antigen that has received much attention is N-glycolyl (NeuGc) GM3. This ganglioside is present in several types of cancer, but is almost undetectable in human healthy tissues. However, its non-hydroxylated variant, NeuAc GM3, is abundant in all mammals. Due to a deletion in the human gene encoding the key enzyme for synthesis of NeuGc, humans, in contrast to other mammals, cannot synthesize NeuGc GM3. Therefore the presence of this ganglioside in human cancer cells represents an enigma. It has been shown that hypoxic conditions trigger the expression of NeuGc gangliosides, which not only serve as attractive targets for cancer therapy, but also as diagnostic and prognostic tumor marker. Here, we confirm hypoxia-induced expression of the NeuGc GM3 ganglioside also in HeLa cells and reveal several candidate proteins, in particular GM3 synthase and subunit B of respiratory complex II (SDHB), that may be involved in the generation of NeuGc GM3 by SILAC-based proteome analysis. These findings have the potential to significantly advance our understanding of how this enigmatic tumor-associated antigen is produced in humans, and also suggest a possible mechanism of action of anti-tumor antibodies that recognize hypoxia markers, such as 14F7. PMID- 29196264 TI - TR47, a PAR1-based peptide, inhibits melanoma cell migration in vitro and metastasis in vivo. AB - Activated Protein C (APC) is a serine-protease that displays antithrombotic and anti-inflammatory properties. In addition, cleavage of protease-activated receptor 1 (PAR1) by APC exerts endothelial cytoprotective actions. The effects of APC on endothelial cells may be reproduced by TR47, a PAR1-based peptide that mimics the novel N-terminus of PAR1 generated upon cleavage at Arg-46 by APC. In this study we demonstrate that wild-type APC and its signaling-proficient mutant, APC-2Cys (which has dramatically reduced anticoagulant activity), display similar inhibitory effects towards the transendothelial migration of A375 human melanoma cells. Consistent with this observation, APC and APC-2Cys significantly reduced the in vivo metastatic potential of the B16F10 murine melanoma cells. TR47 recapitulated the in vitro and in vivo protective profiles of APC and APC-2Cys. Treatment of EA.hy926 endothelial cells with TR47 (20 MUM) significantly decreased the A375 cell migration. In addition, treatment of C57/BL6 mice with a single TR47 dose (125 MUg/animal) strongly reduced the metastatic burden of B16F10 cells. Together, our results suggest that protection of the endothelial barrier by APC/TR47-mediated signaling pathways might be a valuable therapeutic approach to prevent metastasis. PMID- 29196265 TI - Elevated O-GlcNAcylation stabilizes FOXM1 by its reduced degradation through GSK 3beta inactivation in a human gastric carcinoma cell line, MKN45 cells. AB - O-GlcNAcylation is a dynamic post-translational modification of cytonuclear proteins for intracellular signaling. Elevated O-GlcNAcylation is a general feature of cancer and contributes to cancer progression, and recent studies indicate the contribution to increasing incidence of various types of cancer in diabetic patients. However, the role of O-GlcNAcylation in tumor progression is not fully elucidated. Forkhead box M1 (FOXM1), a master mitotic transcription factor, has been implicated in all major hallmarks of cancer, and is wildly expressed in solid tumors. Given that FOXM1 expression was reported to be elevated in gastric cancer, we examined the effect of high glucose or an inhibitor of O-GlcNAc hydrolase, Thiamet G (TMG), on FOXM1 protein expression in a human gastric cancer cell line, MKN45 cells, and confirmed that FOXM1 protein level and the cell proliferation were upregulated. To investigate the molecular mechanisms by which FOXM1 protein expression is regulated by O-GlcNAcylation, the effect of high glucose and TMG on FOXM1 ubiquitination was examined in MKN45 cells. As a result, the ubiquitination and degradation of FOXM1 protein were both suppressed by high glucose and TMG treatment. However, the O-GlcNAcylation was not detected on FOXM1 but not on GSK-3beta. High glucose and TMG treatment increased phospho-serine 9 GSK-3beta, an inactive form, and the degradation of FOXM1 protein was suppressed by treatment of GSK-3beta inhibitors in MKN45 cells. Taken together, we suggest that high glucose and elevated O-GlcNAcylation stabilize FOXM1 protein by its reduced degradation via GSK-3beta inactivation in MKN45 cells, suggesting that the higher risk of gastric cancer in diabetic patients could be partially due to O-GlcNAcylation-mediated FOXM1 stabilization. PMID- 29196266 TI - TIPE2 attenuates liver fibrosis by reversing the activated hepatic stellate cells. AB - TIPE2, the tumor necrosis factor (TNF)-alpha-induced protein 8-like 2 (TNFAIP8L2), plays an important role in regulating inflammation and immune homeostasis. Recent studies discovered that TIPE-2 involved in the development of several tumors and other proliferative diseases. The purpose of this study was to explore the function of TIPE-2 in the activation and proliferation in HSC-T6 cells. Our study showed low expression of TIPE-2 in primary HSCs from CCl4 treated mice and activated HSC-T6 cells. Functionally, over-expression of TIPE-2 by GV141-TIPE-2 hindered the HSC-T6 cells activation and proliferation and expressions of beta-Catenin, Cmyc, Cyclin D1. However, inhibition TIPE-2 expression by TIPE-2 siRNA showed the opposite effect. These observations revealed that TIPE-2 held a protective effect on liver fibrosis and could be a potential therapeutic target. PMID- 29196267 TI - Intrauterine exosomes are required for bovine conceptus implantation. AB - Exosomes, extracellular vesicles, are present in uterine flushing fluids (UFs), which are involved in conceptus-endometrial interactions during peri-implantation periods. Despite several studies on intrauterine exosomes conducted, the roles conceptus and endometrial exosomes play during peri-implantation periods have not been well characterized. To investigate the effect of bovine intrauterine exosomes on conceptus implantation, exosomes isolated from bovine UFs during peri implantation periods were subjected to global protein analysis. The analysis detected 596 exosomal proteins, including ruminants' pregnancy recognition factor IFNT, and 172 differentially expressed proteins with more than 1.5-fold changes in UFs on days 17, 20 and 22 pregnancy (day of conceptus implantation is initiated on days 19-19.5). Treatment of primary bovine endometrial epithelial cells with exosomes from day 17 UFs up-regulated the expression of apoptosis related genes, and treatment with exosomes from day 20 and 22 UFs up-regulated the expression of adhesion molecule. Based on these findings, intrauterine exosomes should be considered as an essential constituent for successful implantation. PMID- 29196268 TI - Developing 3D microscopy with CLARITY on human brain tissue: Towards a tool for informing and validating MRI-based histology. AB - Recent breakthroughs in magnetic resonance imaging (MRI) enabled quantitative relaxometry and diffusion-weighted imaging with sub-millimeter resolution. Combined with biophysical models of MR contrast the emerging methods promise in vivo mapping of cyto- and myelo-architectonics, i.e., in vivo histology using MRI (hMRI) in humans. The hMRI methods require histological reference data for model building and validation. This is currently provided by MRI on post mortem human brain tissue in combination with classical histology on sections. However, this well established approach is limited to qualitative 2D information, while a systematic validation of hMRI requires quantitative 3D information on macroscopic voxels. We present a promising histological method based on optical 3D imaging combined with a tissue clearing method, Clear Lipid-exchanged Acrylamide hybridized Rigid Imaging compatible Tissue hYdrogel (CLARITY), adapted for hMRI validation. Adapting CLARITY to the needs of hMRI is challenging due to poor antibody penetration into large sample volumes and high opacity of aged post mortem human brain tissue. In a pilot experiment we achieved transparency of up to 8 mm-thick and immunohistochemical staining of up to 5 mm-thick post mortem brain tissue by a combination of active and passive clearing, prolonged clearing and staining times. We combined 3D optical imaging of the cleared samples with tailored image processing methods. We demonstrated the feasibility for quantification of neuron density, fiber orientation distribution and cell type classification within a volume with size similar to a typical MRI voxel. The presented combination of MRI, 3D optical microscopy and image processing is a promising tool for validation of MRI-based microstructure estimates. PMID- 29196270 TI - EEG microstates as a tool for studying the temporal dynamics of whole-brain neuronal networks: A review. AB - The present review discusses a well-established method for characterizing resting state activity of the human brain using multichannel electroencephalography (EEG). This method involves the examination of electrical microstates in the brain, which are defined as successive short time periods during which the configuration of the scalp potential field remains semi-stable, suggesting quasi simultaneity of activity among the nodes of large-scale networks. A few prototypic microstates, which occur in a repetitive sequence across time, can be reliably identified across participants. Researchers have proposed that these microstates represent the basic building blocks of the chain of spontaneous conscious mental processes, and that their occurrence and temporal dynamics determine the quality of mentation. Several studies have further demonstrated that disturbances of mental processes associated with neurological and psychiatric conditions manifest as changes in the temporal dynamics of specific microstates. Combined EEG-fMRI studies and EEG source imaging studies have indicated that EEG microstates are closely associated with resting-state networks as identified using fMRI. The scale-free properties of the time series of EEG microstates explain why similar networks can be observed at such different time scales. The present review will provide an overview of these EEG microstates, available methods for analysis, the functional interpretations of findings regarding these microstates, and their behavioral and clinical correlates. PMID- 29196271 TI - Gibson Assembly facilitates bacterial allelic exchange mutagenesis. AB - Allelic exchange mutagenesis that relies on RecA-mediated homologous recombination up- and downstream from the targeted gene is a generalizable method of site-specific bacterial gene knock-out and knock-in. However, generation of a mutagenic DNA construct (alternative allele flanked by regions surrounding the gene target) and subsequent mutant selection are laborious procedures. Here we demonstrate allelic exchange knock-out facilitated by Gibson Assembly in Streptococcus iniae. Gibson Assembly allows rapid construction of a large allelic exchange cassette simultaneous with cloning, as well as rapid reconstruction of complete recombinant vector sequence when required. Additionally, we show that during two-step mutant selection, absence of recombination at one of the homologous regions (single cross-over) might be rapidly detected by colony PCR of meroploid clones and resolved by extension/shifting of corresponding sequence in DNA construct. The combination of Gibson Assembly for mutagenic DNA construction/redesign with colony PCR screening of meroploids to detect recombination at both sides of the exchange target may significantly accelerate generation of chromosomal mutants in a wide range of bacterial taxa. PMID- 29196269 TI - Diffusion MRI and MR spectroscopy reveal microstructural and metabolic brain alterations in chronic mild stress exposed rats: A CMS recovery study. AB - Chronic mild stress (CMS) induced depression elicits several debilitating symptoms and causes a significant economic burden on society. High variability in the symptomatology of depression poses substantial impediment to accurate diagnosis and therapy outcome. CMS exposure induces significant metabolic and microstructural alterations in the hippocampus (HP), prefrontal cortex (PFC), caudate-putamen (CP) and amygdala (AM), however, recovery from these maladaptive changes are limited and this may provide negative effects on the therapeutic treatment and management of depression. The present study utilized anhedonic rats from the unpredictable CMS model of depression to study metabolic recovery in the ventral hippocampus (vHP) and microstructural recovery in the HP, AM, CP, and PFC. The study employed 1H MR spectroscopy (1H MRS) and in-vivo diffusion MRI (d MRI) at the age of week 18 (week 1 post CMS exposure) week 20 (week 3 post CMS) and week 25 (week 8 post CMS exposure) in the anhedonic group, and at the age of week 18 and week 22 in the control group. The d-MRI data have provided an array of diffusion tensor metrics (FA, MD, AD, and RD), and fast kurtosis metrics (MKT, WL and WT). CMS exposure induced a significant metabolic alteration in vHP, and significant microstructural alterations were observed in the HP, AM, and PFC in comparison to the age match control and within the anhedonic group. A significantly high level of N-acetylaspartate (NAA) was observed in vHP at the age of week 18 in comparison to age match control and week 20 and week 25 of the anhedonic group. HP and AM showed significant microstructural alterations up to the age of week 22 in the anhedonic group. PFC showed significant microstructural alterations only at the age of week 18, however, most of the metrics showed significantly higher value at the age of week 20 in the anhedonic group. The significantly increased NAA concentration may indicate impaired catabolism due to astrogliosis or oxidative stress. The significantly increased WL in the AM and HP may indicate hypertrophy of AM and reduced volume of HP. Such metabolic and microstructural alterations could be useful in disease diagnosis and follow-up treatment intervention in depression and similar disorders.

AB - Capillary blood collected in serum tubes was subjected to centrifugation delay while stored at room temperature. Chlamydia trachomatis (CT) IgG concentrations in aliquoted serum of these blood samples remained stable for seven days after collection. CT IgG concentrations can reliably be measured in mailed blood samples in epidemiological studies. PMID- 29196273 TI - Optimising the in vitro and in vivo performance of oral cocrystal formulations via spray coating. AB - Engineering of pharmaceutical cocrystals is an advantageous alternative to salt formation for improving the aqueous solubility of hydrophobic drugs. Although, spray drying is a well-established scale-up technique in the production of cocrystals, several issues can arise such as sublimation or stickiness due to low glass transition temperatures of some organic molecules, making the process very challenging. Even though, fluidised bed spray coating has been successfully employed in the production of amorphous drug-coated particles, to the best of our knowledge, it has never been employed in the production of cocrystals. The feasibility of this technique was proven using three model cocrystals: sulfadimidine (SDM)/4-aminosalicylic acid (4ASA), sulfadimidine/nicotinic acid (NA) and ibuprofen (IBU)/ nicotinamide (NAM). Design of experiments were performed to understand the critical formulation and process parameters that determine the formation of either cocrystal or coamorphous systems for SDM/4ASA. The amount and type of binder played a key role in the overall solid state and in vitro performance characteristics of the cocrystals. The optimal balance between high loading efficiencies and high degree of crystallinity was achieved only when a binder: cocrystal weight ratio of 5:95 or 10:90 was used. The cocrystal coated beads showed an improved in vitro-in vivo performance characterised by: (i) no tendency to aggregate in aqueous media compared to spray dried formulations, (ii) enhanced in vitro activity (1.8-fold greater) against S. aureus, (iii) larger oral absorption and bioavailability (2.2-fold higher Cmax), (iv) greater flow properties and (v) improved chemical stability than cocrystals produced by other methods derived from the morphology and solid nature of the starter cores. PMID- 29196274 TI - Neuromuscular diseases: Diagnosis and management. AB - Neuromuscular diseases (NMDs) affect the peripheral nervous system, which includes the motor neurons and sensory neurons; the muscle itself; or the neuromuscular junction. Thus, the term NMDs encompasses a vast array of different syndromes. Some of these syndromes are of direct relevance to paediatric orthopaedic surgeons, either because the presenting manifestation is a functional sign (e.g., toe-walking) or deformity (e.g., pes cavus or scoliosis) suggesting a need for orthopaedic attention or because orthopaedic abnormalities requiring treatment develop during the course of a known NMD. The main NMDs relevant to the orthopaedic surgeon are infantile spinal muscular atrophy (a motor neuron disease), peripheral neuropathies (chiefly, Charcot-Marie-Tooth disease), congenital muscular dystrophies, progressive muscular dystrophies, and Steinert myotonic dystrophy (or myotonic dystrophy type 1). Muscle weakness is a symptom shared by all these conditions. The paediatric orthopaedic surgeon must be familiar, not only with the musculoskeletal system, but also with many other domains (particularly respiratory and cardiac function and nutrition) that may interfere with the treatment and require preoperative management. Good knowledge of the natural history of each NMD is essential to ensure optimal timing of the therapeutic interventions, which must be performed under the best possible conditions in these usually frail patients. Timing is particularly crucial for the treatment of spinal deformities due to paraspinal muscle hypotonia during growth: depending on the disease and natural history, the treatment may involve non-operative methods or growing rods, followed by spinal fusion. A multidisciplinary approach is always required. Finally, the survival gains achieved in recent years increasingly require attention to preparing for adult life, to orthopaedic problems requiring treatment before the patient leaves the paediatric environment, and to the transition towards the adult healthcare system. PMID- 29196275 TI - Global risk mapping for major diseases transmitted by Aedes aegypti and Aedes albopictus. AB - OBJECTIVES: The objective of this study was to map the global risk of the major arboviral diseases transmitted by Aedes aegypti and Aedes albopictus by identifying areas where the diseases are reported, either through active transmission or travel-related outbreaks, as well as areas where the diseases are not currently reported but are nonetheless suitable for the vector. METHODS: Data relating to five arboviral diseases (Zika, dengue fever, chikungunya, yellow fever, and Rift Valley fever (RVF)) were extracted from some of the largest contemporary databases and paired with data on the known distribution of their vectors, A. aegypti and A. albopictus. The disease occurrence data for the selected diseases were compiled from literature dating as far back as 1952 to as recent as 2017. The resulting datasets were aggregated at the country level, except in the case of the USA, where state-level data were used. Spatial analysis was used to process the data and to develop risk maps. RESULTS: Out of the 250 countries/territories considered, 215 (86%) are potentially suitable for the survival and establishment of A. aegypti and/or A. albopictus. A. albopictus has suitability foci in 197 countries/territories, while there are 188 that are suitable for A. aegypti. There is considerable variation in the suitability range among countries/territories, but many of the tropical regions of the world provide high suitability over extensive areas. Globally, 146 (58.4%) countries/territories reported at least one arboviral disease, while 123 (49.2%) reported more than one of the above diseases. The overall numbers of countries/territories reporting autochthonous vector-borne occurrences of Zika, dengue, chikungunya, yellow fever, and RVF, were 85, 111, 106, 43, and 39, respectively. CONCLUSIONS: With 215 countries/territories potentially suitable for the most important arboviral disease vectors and more than half of these reporting cases, arboviral diseases are indeed a global public health threat. The increasing proportion of reports that include multiple arboviral diseases highlights the expanding range of their common transmission vectors. The shared features of these arboviral diseases should motivate efforts to combine interventions against these diseases. PMID- 29196276 TI - Next-generation sequencing of the cerebrospinal fluid in the diagnosis of neurobrucellosis. AB - BACKGROUND: Brucellosis is the most common zoonotic infection in the world. Brucellosis with nervous system involvement is known as 'neurobrucellosis' (NB). The diagnosis of NB is difficult because its clinical manifestations are non specific and the sensitivity of routine culture tests is low. METHODS: Next generation sequencing (NGS) of cerebrospinal fluid (CSF) was used to detect pathogens in patients with clinically suspected central nervous system (CNS) infections at a tertiary referral center in China between June 1, 2016 and June 1, 2017. The clinical characteristics and NGS results of patients with the diagnosis of NB were reviewed in this study. RESULTS: Four patients were rapidly diagnosed with NB using NGS of the CSF in patients with clinically suspected CNS infections, although the clinical manifestations varied dramatically between these patients. NGS of the CSF revealed that the sequence reads identified that corresponded to Brucella species ranged from 11 to 104, with genomic coverage ranging from 0.043% to 0.4%. Rapid diagnosis led to prompt treatment with the appropriate antibiotics. CONCLUSIONS: This study demonstrates the power of NGS of the CSF coupled with a bioinformatic pipeline in the diagnosis of NB. PMID- 29196277 TI - Clinical and epidemiological features of chronic Trypanosoma cruzi infection in patients with HIV/AIDS in Buenos Aires, Argentina. AB - OBJECTIVES: Trypanosoma cruzi reactivation in HIV patients is considered an opportunistic infection, usually with a fatal outcome. The aim of this study was to describe the epidemiological and clinical features of T. cruzi infection in HIV patients and to compare these findings between patients with and without Chagas disease reactivation. METHODS: The medical records of T. cruzi-HIV co infected patients treated at the Muniz Infectious Diseases Hospital from January 2005 to December 2014 were reviewed retrospectively. Epidemiological and clinical features were assessed and compared between patients with and without Chagas disease reactivation. RESULTS: The medical records of 80 T. cruzi-HIV co-infected patients were reviewed. The most likely route of T. cruzi infection was vector borne (32/80 patients), followed by intravenous drug use (12/80). Nine of 80 patients had reactivation. Patients without reactivation had a significantly higher CD4 T-cell count at diagnosis of T. cruzi infection (144 cells/MUl vs. 30 cells/MUl, p=0.026). Chagas disease serology was negative in two of nine patients with reactivation. CONCLUSIONS: Serological assays for T. cruzi infection may be negative in severely immunocompromised patients. Direct parasitological techniques should be performed in the diagnosis of patients for whom there is a suspicion of T. cruzi reactivation. HIV patients with a lower CD4 count are at higher risk of reactivation. PMID- 29196278 TI - Discrepancies Between Classic and Digital Epidemiology in Searching for the Mayaro Virus: Preliminary Qualitative and Quantitative Analysis of Google Trends. AB - BACKGROUND: Mayaro virus (MAYV), first discovered in Trinidad in 1954, is spread by the Haemagogus mosquito. Small outbreaks have been described in the past in the Amazon jungles of Brazil and other parts of South America. Recently, a case was reported in rural Haiti. OBJECTIVE: Given the emerging importance of MAYV, we aimed to explore the feasibility of exploiting a Web-based tool for monitoring and tracking MAYV cases. METHODS: Google Trends is an online tracking system. A Google-based approach is particularly useful to monitor especially infectious diseases epidemics. We searched Google Trends from its inception (from January 2004 through to May 2017) for MAYV-related Web searches worldwide. RESULTS: We noted a burst in search volumes in the period from July 2016 (relative search volume [RSV]=13%) to December 2016 (RSV=18%), with a peak in September 2016 (RSV=100%). Before this burst, the average search activity related to MAYV was very low (median 1%). MAYV-related queries were concentrated in the Caribbean. Scientific interest from the research community and media coverage affected digital seeking behavior. CONCLUSIONS: MAYV has always circulated in South America. Its recent appearance in the Caribbean has been a source of concern, which resulted in a burst of Internet queries. While Google Trends cannot be used to perform real-time epidemiological surveillance of MAYV, it can be exploited to capture the public's reaction to outbreaks. Public health workers should be aware of this, in that information and communication technologies could be used to communicate with users, reassure them about their concerns, and to empower them in making decisions affecting their health. PMID- 29196280 TI - Search and Graph Database Technologies for Biomedical Semantic Indexing: Experimental Analysis. AB - BACKGROUND: Biomedical semantic indexing is a very useful support tool for human curators in their efforts for indexing and cataloging the biomedical literature. OBJECTIVE: The aim of this study was to describe a system to automatically assign Medical Subject Headings (MeSH) to biomedical articles from MEDLINE. METHODS: Our approach relies on the assumption that similar documents should be classified by similar MeSH terms. Although previous work has already exploited the document similarity by using a k-nearest neighbors algorithm, we represent documents as document vectors by search engine indexing and then compute the similarity between documents using cosine similarity. Once the most similar documents for a given input document are retrieved, we rank their MeSH terms to choose the most suitable set for the input document. To do this, we define a scoring function that takes into account the frequency of the term into the set of retrieved documents and the similarity between the input document and each retrieved document. In addition, we implement guidelines proposed by human curators to annotate MEDLINE articles; in particular, the heuristic that says if 3 MeSH terms are proposed to classify an article and they share the same ancestor, they should be replaced by this ancestor. The representation of the MeSH thesaurus as a graph database allows us to employ graph search algorithms to quickly and easily capture hierarchical relationships such as the lowest common ancestor between terms. RESULTS: Our experiments show promising results with an F1 of 69% on the test dataset. CONCLUSIONS: To the best of our knowledge, this is the first work that combines search and graph database technologies for the task of biomedical semantic indexing. Due to its horizontal scalability, ElasticSearch becomes a real solution to index large collections of documents (such as the bibliographic database MEDLINE). Moreover, the use of graph search algorithms for accessing MeSH information could provide a support tool for cataloging MEDLINE abstracts in real time. PMID- 29196279 TI - Using mHealth Technology in a Self-Management Intervention to Promote Physical Activity Among Adults With Chronic Disabling Conditions: Randomized Controlled Trial. AB - BACKGROUND: Physical activity is considered a comprehensive approach for managing limitations in physical function among adults with chronic disabling conditions. However, adults with chronic disabling conditions often face many barriers to engaging in physical activity. A strategy to promote physical activity among adults with chronic disabling conditions is to encourage the use of mobile health (mHealth) apps. OBJECTIVE: The objective of this pilot study was to examine the potential benefits of using commercially available mHealth apps in a self management intervention among 46 adults with musculoskeletal or neurological conditions. METHODS: Participants were randomized to one of 3 intervention groups: (1) mHealth-based self-management intervention, (2) paper-based self management intervention, and (3) contact-control intervention. Participants in all 3 groups met in person once and received 3 follow-up phone calls with a trained graduate assistant. Participants in the mHealth-based and paper-based groups received a computer tablet or a paper diary, respectively, to facilitate goal setting, self-monitoring, and action planning. Participants in the contact control group received information on healthy behaviors without being taught skills to change behaviors. The following outcomes were measured at baseline and at the 7th week: physical activity (Physical Activity and Disability Survey revised), psychosocial factors (self-efficacy, self-regulation, and social support), and physical function (Patient Report Outcomes Measurement Information System, 6-min walk test, 1-min chair stands, and 1-min arm curls). RESULTS: Repeated-measures multivariate analysis of variance (MANOVA) indicated significant differences between groups in physical activity levels (Wilks lambda=0.71, F6,76=2.34, P=.04). Both the mHealth-based and paper-based groups had large effect size increases in planned exercise and leisure-time physical activity compared with the contact-control group (Cohen d=1.20 and d=0.82, respectively). Repeated-measures MANOVA indicated nonsignificant differences between groups in psychosocial factors (Wilks lambda=0.85, F6,76=1.10, P=.37). However, both the mHealth-based and paper-based groups had moderate effect size improvements in self-efficacy (d=0.48 and d=0.75, respectively) and self regulation (d=0.59 and d=0.43, respectively) compared with the contact-control group. Repeated-measures MANOVA indicated nonsignificant differences between groups in physical function (Wilks lambda=0.94, F8,66=0.27, P=.97). There were small and nonsignificant changes between the mHealth-based and paper-based groups with regard to most outcomes. However, the mHealth-based group had moderate effect size increases (d=0.47) in planned exercise and leisure-time physical activity compared with the paper-based group. CONCLUSIONS: We found that using commercially available mHealth apps in a self-management intervention shows promise in promoting physical activity among adults with musculoskeletal and neurological conditions. Further research is needed to identify the best ways of using commercially available mobile apps in self-management interventions.

PMID- 29196281 TI - The Use of Avatar Counseling for HIV/AIDS Health Education: The Examination of Self-Identity in Avatar Preferences. AB - BACKGROUND: The number of adults using the Internet to obtain health information is on the rise. An estimated 66% of the adults reportedly use the Internet to obtain health information related to a specific disease (ie, human immunodeficiency virus and acquired immunodeficiency syndrome, HIV/AIDS). Previous research has demonstrated that health information seekers use the Internet to seek answers to stigma-laden questions from health avatars. OBJECTIVE: The objective of this study was to identify patterns in the choice of avatar among health information seekers (patients or public health workers) using the Internet to obtain HIV/AIDS information and to describe the demographic characteristics (age, gender, and ethnicity) of health information seekers to determine whether they preferred an avatar that was similar to their own gender and ethnicity. METHODS: The Rural South Public Health Training Center (RSPHTC) partnered with the New York State Department of Health to create the HIV/AIDS Avatar project. The avatar project was created to serve as an educational resource for public health workers by providing relevant and accurate information about HIV/AIDS. First, the user was instructed to choose one of the 8 avatars that voiced responses to 100 common questions and answers about HIV/AIDS. Next, the website gave users the option to complete a brief 3-question demographic survey. Finally, the demographic characteristics of each user were compared with the chosen avatar to determine whether they preferred an avatar that was similar to their own gender and ethnicity. RESULTS: The avatar project website was loaded with 800 videos that included the answers to the top 100 questions about HIV/AIDS voiced by 8 avatars. A total of 1119 Web-based health information seekers completed the demographic survey upon accessing the website. Of these, 55.14% (617/1119) users were female. A total of 49.96% (559/1119) users were aged between 30 and 49 years. The ethnicity of the user and the avatar was found to have the strongest connection. All the users choose the female avatar matching their own ethnicity, followed by the male avatar. Additionally, the white female avatar was chosen the most by all users regardless of the age group or gender. CONCLUSIONS: Web-based health information seekers using the Internet to access medical research information may feel more comfortable receiving the answers to HIV stigma-laden questions from avatars, rather than receiving information directly from a health care provider. Additionally, providers seeking to utilize avatars to deliver interventions in health care settings may benefit from offering individuals choices in how they receive health information. Having the ability to choose whom you seek information from may lead to an increase in knowledge and awareness and could motivate HIV-positive individuals to seek care. PMID- 29196282 TI - Reducing variations in care. PMID- 29196283 TI - Ringed telangiectasias: an unusual presentation of telangiectasia macularis eruptiva perstans. AB - Telangiectasia macularis eruptiva perstans (TMEP) is a rare form of cutaneous mastocytosis. While most cutaneous mastocytoses occur in children and are asymptomatic, TMEP occurs predominantly in adults and is associated with systemic manifestations, requiring medical management. TMEP is typically characterised by scattered red-brown macules on the trunk and extremities, but must be differentiated from other telangiectatic conditions such as scleroderma, hereditary haemorrhagic telangiectasia and telangiectasias secondary to cirrhosis. Practitioners must be aware that variants to the classic presentation of TMEP exist, such as the ringed telangiectasias we describe. Diagnostic workup including tissue biopsy must be considered in such patients after a thorough history and physical have been performed and other telangiectatic processes have been ruled out. The treatment of cutaneous mastocytosis aims at controlling symptoms and preventing mast cell degranulation. Cosmetic treatment includes the use ofPsoralen and ultraviolet A (PUVA) therapy, total skin electron beam radiation and flashlamp pulsed-dye laser treatment.

AB - Cardiac manifestations of subarachnoid haemorrhage (SAH) are well-documented phenomena that can complicate the treatment of this devastating condition. Here, we present a case of SAH presenting as complete heart block on initial assessment, an extremely rare event.A 53-year-old woman presented with a witnessed fall, sustaining a mild head injury. She denied any symptoms of SAH. Initial ECG revealed complete heart block, for which the patient was accepted under the cardiology team. For completion, a CT head scan was requested, this demonstrated significant SAH blood load in an aneurysmal rather than traumatic pattern. CT angiogram and subsequent digital subtraction angiography confirmed a posterior communicating artery aneurysm as the cause of the SAH. This case highlights the importance of considering neurological diagnoses in patients with collapse even with concomitant cardiac abnormalities, as the two are often inextricably linked.

PMID- 29196287 TI - Denitrification by Anaeromyxobacter dehalogenans, a Common Soil Bacterium Lacking Nitrite Reductase Genes (nirS/nirK). AB - The versatile soil bacterium Anaeromyxobacter dehalogenans lacks the hallmark denitrification genes nirS and nirK (NO2-->NO), and couples growth to NO3- reduction to NH4+ (respiratory ammonification) and to N2O reduction to N2A. dehalogenans also grows by reducing Fe(III) to Fe(II), which chemically reacts with NO2- to form N2O (i.e., chemodenitrification). Following the addition of 100 MUmoles of NO3- or NO2- to Fe(III)-grown, axenic cultures of A. dehalogenans, 54 (+/-7) MUmoles and 113 (+/-2) MUmoles N2O-N, respectively, were produced and subsequently consumed. The conversion of NO3- to N2 in the presence of Fe(II) through linked biotic-abiotic reactions represents an unrecognized ecophysiology of A. dehalogenans The new findings demonstrate that the assessment of gene content alone is insufficient to predict microbial denitrification potential and N loss (i.e., the formation of gaseous N products). A survey of complete bacterial genomes in the NCBI Reference Sequence database coupled with available physiological information revealed that organisms lacking nirS/nirK but with Fe(III) reduction potential and genes for NO3- and N2O reduction are not rare, indicating that NO3- reduction to N2 through linked biotic-abiotic reactions is not limited to A. dehalogenans Considering the ubiquity of iron in soils and sediments and the broad distribution of dissimilatory Fe(III) and NO3- reducers, denitrification independent of NO-forming NO2- reductases (through combined biotic-abiotic reactions) may have substantial contributions to N loss and N2O flux.Importance Current attempts to gauge N loss from soils rely on the quantitative measurement of nirK and nirS genes and/or transcripts. In the presence of iron, the common soil bacterium Anaeromyxobacter dehalogenans is capable of denitrification and producing N2 without the key denitrification genes nirK/nirS Such chemodenitrifiers denitrify through combined biotic and abiotic reactions and have potentially large contributions to N loss to the atmosphere, and fill a heretofore unrecognized ecological niche in soil ecosystems. The findings emphasize that comprehensive understanding of N flux and accurate assessment of denitrification potential can only be achieved when integrated studies of interlinked biogeochemical cycles are performed. PMID- 29196288 TI - Pathway for the Biosynthesis of the Pigment Chrysogine by Penicillium chrysogenum. AB - Chrysogine is a yellow pigment produced by Penicillium chrysogenum and other filamentous fungi. Although the pigment was first isolated in 1973, its biosynthetic pathway has so far not been resolved. Here, we show that deletion of the highly expressed nonribosomal peptide synthetase (NRPS) gene Pc21g12630 (chyA) resulted in a decrease in the production of chrysogine and 13 related compounds in the culture broth of P. chrysogenum Each of the genes of the chyA containing gene cluster was individually deleted, and corresponding mutants were examined by metabolic profiling in order to elucidate their function. The data suggest that the NRPS ChyA mediates the condensation of anthranilic acid and alanine into the intermediate 2-(2-aminopropanamido)benzoic acid, which was verified by feeding experiments of a DeltachyA strain with the chemically synthesized product. The remainder of the pathway is highly branched, yielding at least 13 chrysogine-related compounds.IMPORTANCEPenicillium chrysogenum is used in industry for the production of beta-lactams, but also produces several other secondary metabolites. The yellow pigment chrysogine is one of the most abundant metabolites in the culture broth, next to beta-lactams. Here, we have characterized the biosynthetic gene cluster involved in chrysogine production and elucidated a complex and highly branched biosynthetic pathway, assigning each of the chrysogine cluster genes to biosynthetic steps and metabolic intermediates. The work further unlocks the metabolic potential of filamentous fungi and the complexity of secondary metabolite pathways. PMID- 29196289 TI - Poly-3-Hydroxybutyrate Functionalization with BioF-Tagged Recombinant Proteins. AB - Polyhydroxyalkanoates (PHAs) are biodegradable polyesters that accumulate in the cytoplasm of certain bacteria. One promising biotechnological application utilizes these biopolymers as supports for protein immobilization. Here, the PHA binding domain of the Pseudomonas putida KT2440 PhaF phasin (BioF polypeptide) was investigated as an affinity tag for the in vitro functionalization of poly-3 hydroxybutyrate (PHB) particles with recombinant proteins, namely, full-length PhaF and two fusion proteins tagged to BioF (BioF-C-LytA and BioF-beta galactosidase, containing the choline-binding module C-LytA and the beta galactosidase enzyme, respectively). The protein-biopolyester interaction was strong and stable at a wide range of pHs and temperatures, and the bound protein was highly protected from self-degradation, while the binding strength could be modulated by coating with amphiphilic compounds. Finally, BioF-beta-galactosidase displayed very stable enzymatic activity after several continuous activity-plus washing cycles when immobilized in a minibioreactor. Our results demonstrate the potentialities of PHA and the BioF tag for the construction of novel bioactive materials.IMPORTANCE Our results confirm the biotechnological potential of the BioF affinity tag as a versatile tool for functionalizing PHA supports with recombinant proteins, leading to novel bioactive materials. The wide substrate range of the BioF tag presumably enables protein immobilization in vitro of virtually all natural PHAs as well as blends, copolymers, or artificial chemically modified derivatives with novel physicochemical properties. Moreover, the strength of protein adsorption may be easily modulated by varying the coating of the support, providing new perspectives for the engineering of bioactive materials that require a tight control of protein loading. PMID- 29196290 TI - Evolution and Diversity of Inherited Spiroplasma Symbionts in Myrmica Ants. AB - Microbial partners play important roles in the biology and ecology of animals. In insects, maternally transmitted symbionts are especially common and can have host effects ranging from reproductive manipulation to nutrient provisioning and defense against natural enemies. In this study, we report a genus-wide association of Myrmica ants with the inherited bacterial symbiont Spiroplasma We screen Myrmica ants collected from the wild, including the invasive European fire ant, Myrmica rubra, and find an extraordinarily high prevalence of this symbiont 8 of 9 species, 42 of 43 colonies, and 250 of 276 individual workers harbored Spiroplasma-only one host species was uninfected. In our screens, each host species carried a distinct Spiroplasma strain, and none were infected with more than one strain. All symbionts belong to the citri clade, allied most closely with pathogenic strains of Spiroplasma infecting corn crops and honeybees, and there is strong evidence of host-symbiont persistence across evolutionary time scales. Genome sequencing of two Spiroplasma symbionts revealed candidate genes that may play a part in the symbiosis, a nutrient transporter absent from other Spiroplasma strains, and a ribosome-inactivating protein previously implicated in parasite defense. These results together suggest long-term, likely mutualistic, relationships atypical of Spiroplasma-insect associations with potential significance for broad ecological interactions with MyrmicaIMPORTANCE Animal associated microbial symbionts can dramatically affect the biology of their hosts. The identification and characterization of these intimate partnerships remain an essential component of describing and predicting species interactions, especially for invasive host species. Ants perform crucial ecological functions as ecosystem engineers, scavengers, and predators, and ants in the genus Myrmica can be aggressive resource competitors and reach high densities in their native and invaded habitats. In this study, a novel symbiosis is identified between Myrmica ants and the facultative bacterial symbiont Spiroplasma Broad host distribution, high frequencies of infection, and host-symbiont codivergence over evolutionary time scales, an uncommon feature of Spiroplasma associations, suggest an important likely mutualistic interaction. Genome sequencing identified highly divergent gene candidates that may contribute to Spiroplasma's role as a possible defensive or nutritional partner in Myrmica. PMID- 29196292 TI - Gut Microbiota in Human Systemic Lupus Erythematosus and a Mouse Model of Lupus. AB - Gut microbiota dysbiosis has been observed in a number of autoimmune diseases. However, the role of the gut microbiota in systemic lupus erythematosus (SLE), a prototypical autoimmune disease characterized by persistent inflammation in multiple organs of the body, remains elusive. Here we report the dynamics of the gut microbiota in a murine lupus model, NZB/W F1, as well as intestinal dysbiosis in a small group of SLE patients with active disease. The composition of the gut microbiota changed markedly before and after the onset of lupus disease in NZB/W F1 mice, with greater diversity and increased representation of several bacterial species as lupus progressed from the predisease stage to the diseased stage. However, we did not control for age and the cage effect. Using dexamethasone as an intervention to treat SLE-like signs, we also found that a greater abundance of a group of lactobacilli (for which a species assignment could not be made) in the gut microbiota might be correlated with more severe disease in NZB/W F1 mice. Results of the human study suggest that, compared to control subjects without immune-mediated diseases, SLE patients with active lupus disease possessed an altered gut microbiota that differed in several particular bacterial species (within the genera Odoribacter and Blautia and an unnamed genus in the family Rikenellaceae) and was less diverse, with increased representation of Gram negative bacteria. The Firmicutes/Bacteroidetes ratios did not differ between the SLE microbiota and the non-SLE microbiota in our human cohort.IMPORTANCE SLE is a complex autoimmune disease with no known cure. Dysbiosis of the gut microbiota has been reported for both mice and humans with SLE. In this emerging field, however, more studies are required to delineate the roles of the gut microbiota in different lupus-prone mouse models and people with diverse manifestations of SLE. Here, we report changes in the gut microbiota in NZB/W F1 lupus-prone mice and a group of SLE patients with active disease. PMID- 29196291 TI - Shotgun Metagenomics and Volatilome Profile of the Microbiota of Fermented Sausages. AB - Changes in the microbial gene content and abundance can be analyzed to detect shifts in the microbiota composition due to the use of a starter culture in the food fermentation process, with the consequent shift of key metabolic pathways directly connected with product acceptance. Meat fermentation is a complex process involving microbes that metabolize the main components in meat. The breakdown of carbohydrates, proteins, and lipids can lead to the formation of volatile organic compounds (VOCs) that can drastically affect the organoleptic characteristics of the final products. The present meta-analysis, performed with the shotgun DNA metagenomic approach, focuses on studying the microbiota and its gene content in an Italian fermented sausage produced by using a commercial starter culture (a mix of Lactobacillus sakei and Staphylococcus xylosus), with the aim to discover the connections between the microbiota, microbiome, and the release of volatile metabolites during ripening. The inoculated fermentation with the starter culture limited the development of Enterobacteriaceae and reduced the microbial diversity compared to that from spontaneous fermentation. KEGG database genes associated with the reduction of acetaldehyde to ethanol (EC 1.1.1.1), acetyl phosphate to acetate (EC 2.7.2.1), and 2,3-butanediol to acetoin (EC 1.1.1.4) were most abundant in inoculated samples (I) compared to those in spontaneous fermentation samples (S). The volatilome profiles were highly consistent with the abundance of the genes; elevated acetic acid (1,173.85 MUg/kg), ethyl acetate (251.58 MUg/kg), and acetoin (1,100.19 MUg/kg) were observed in the presence of the starters at the end of fermentation. Significant differences were found in the liking of samples based on flavor and odor, suggesting a higher preference by consumers for the spontaneous fermentation samples. Inoculated samples exhibited the lowest scores for the liking data, which were clearly associated with the highest concentration of acetic acid.IMPORTANCE We present an advance in the understanding of meat fermentation by coupling DNA sequencing metagenomics and metabolomics approaches to describe the microbial function during this process. Very few studies using this global approach have been dedicated to food, and none have examined sausage fermentation, underlying the originality of the study. The starter culture drastically affected the organoleptic properties of the products. This finding underlines the importance of starter culture selection that takes into consideration the functional characteristics of the microorganism to optimize production efficiency and product quality. PMID- 29196293 TI - 3,6-Dichlorosalicylate Catabolism Is Initiated by the DsmABC Cytochrome P450 Monooxygenase System in Rhizorhabdus dicambivorans Ndbn-20. AB - The degradation of the herbicide dicamba is initiated by demethylation to form 3,6-dichlorosalicylate (3,6-DCSA) in Rhizorhabdusdicambivorans Ndbn-20. In the present study, a 3,6-DCSA degradation-deficient mutant, Ndbn-20m, was screened. A cluster, dsmR1DABCEFGR2, was lost in this mutant. The cluster consisted of nine genes, all of which were apparently induced by 3,6-DCSA. DsmA shared 30 to 36% identity with the monooxygenase components of reported three-component cytochrome P450 systems and formed a monophyletic branch in the phylogenetic tree. DsmB and DsmC were most closely related to the reported [2Fe-2S] ferredoxin and ferredoxin reductase, respectively. The disruption of dsmA in strain Ndbn-20 resulted in inactive 3,6-DCSA degradation. When dsmABC, but not dsmA alone, was introduced into mutant Ndbn-20m and Sphingobium quisquiliarum DC-2 (which is unable to degrade salicylate and its derivatives), they acquired the ability to hydroxylate 3,6-DCSA. Single-crystal X-ray diffraction demonstrated that the DsmABC-catalyzed hydroxylation occurred at the C-5 position of 3,6-DCSA, generating 3,6 dichlorogentisate (3,6-DCGA). In addition, DsmD shared 51% identity with GtdA (a gentisate and 3,6-DCGA 1,2-dioxygenase) from Sphingomonas sp. strain RW5. However, unlike GtdA, the purified DsmD catalyzed the cleavage of gentisate and 3 chlorogentisate but not 6-chlorogentisate or 3,6-DCGA in vitro Based on the bioinformatic analysis and gene function studies, a possible catabolic pathway of dicamba in R. dicambivorans Ndbn-20 was proposed.IMPORTANCE Dicamba is widely used to control a variety of broadleaf weeds and is a promising target herbicide for the engineering of herbicide-resistant crops. The catabolism of dicamba has thus received increasing attention. Bacteria mineralize dicamba initially via demethylation, generating 3,6-dichlorosalicylate. However, the catabolism of 3,6 dichlorosalicylate remains unknown. In this study, we cloned a gene cluster, dsmR1DABCEFGR2, involved in 3,6-dichlorosalicylate degradation from R. dicambivorans Ndbn-20, demonstrated that the cytochrome P450 monooxygenase system DsmABC was responsible for the 5-hydroxylation of 3,6-dichlorosalicylate, and proposed a dicamba catabolic pathway. This study provides a basis to elucidate the catabolism of dicamba and has benefits for the ecotoxicological study of dicamba. Furthermore, the hydroxylation of salicylate has been previously reported to be catalyzed by single-component flavoprotein or three-component Rieske non-heme iron oxygenase, whereas DsmABC was the only cytochrome P450 monooxygenase system hydroxylating salicylate and its methyl- or chloro substituted derivatives. PMID- 29196294 TI - Enhanced Wort Fermentation with De Novo Lager Hybrids Adapted to High-Ethanol Environments. AB - Interspecific hybridization is a valuable tool for developing and improving brewing yeast in a number of industry-relevant aspects. However, the genomes of newly formed hybrids can be unstable. Here, we exploited this trait by adapting four brewing yeast strains, three of which were de novo interspecific lager hybrids with different ploidy levels, to high ethanol concentrations in an attempt to generate variant strains with improved fermentation performance in high-gravity wort. Through a batch fermentation-based adaptation process and selection based on a two-step screening process, we obtained eight variant strains which we compared to the wild-type strains in 2-liter-scale wort fermentations replicating industrial conditions. The results revealed that the adapted variants outperformed the strains from which they were derived, and the majority also possessed several desirable brewing-relevant traits, such as increased ester formation and ethanol tolerance, as well as decreased diacetyl formation. The variants obtained from the polyploid hybrids appeared to show greater improvements in fermentation performance than those derived from diploid strains. Interestingly, it was not only the hybrid strains, but also the Saccharomyces cerevisiae parent strain, that appeared to adapt and showed considerable changes in genome size. Genome sequencing and ploidy analysis revealed that changes had occurred at both the chromosome and single nucleotide levels in all variants. Our study demonstrates the possibility of improving de novo lager yeast hybrids through adaptive evolution by generating stable and superior variants that possess traits relevant to industrial lager beer fermentation.IMPORTANCE Recent studies have shown that hybridization is a valuable tool for creating new and diverse strains of lager yeast. Adaptive evolution is another strain development tool that can be applied in order to improve upon desirable traits. Here, we apply adaptive evolution to newly created lager yeast hybrids by subjecting them to environments containing high ethanol levels. We isolated and characterized a number of adapted variants which possess improved fermentation properties and ethanol tolerance. Genome analysis revealed substantial changes in the variants compared to the original strains. These improved variant strains were produced without any genetic modification and are suitable for industrial lager beer fermentations. PMID- 29196295 TI - Quasi-metagenomics and realtime sequencing aided detection and subtyping of Salmonella enterica from food samples. AB - Metagenomics analysis of food samples promises isolation-independent detection and subtyping of foodborne bacterial pathogens in a single workflow. Selective concentration of Salmonella genomic DNA through immunomagnetic separation (IMS) and multiple displacement amplification (MDA) were shown to shorten culture enrichment of Salmonella-spiked raw chicken breast samples by over 12 hours while permitting serotyping and high-fidelity single nucleotide polymorphisms (SNP) typing of the pathogen using short shotgun sequencing reads. The herein termed quasi-metagenomics approach was evaluated on Salmonella-spiked lettuce and black peppercorn samples as well as retail chicken parts naturally contaminated with different serotypes of Salmonella. Between 8 and 24 h culture enrichment was required for detecting and subtyping naturally occurring Salmonella from unspiked chicken parts compared with 4 to 12 h culture enrichment when Salmonella-spiked food samples were analyzed, indicating the likely need for longer culture enrichment to revive low levels of stressed or injured Salmonella cells in food. Further acceleration of the workflow was achieved by real-time nanopore sequencing. After 1.5 hours of analysis on a potable sequencer, sufficient data were generated from sequencing IMS-MDA product of a cultured-enriched lettuce sample to allow serotyping and robust phylogenetic placement of the inoculated isolate.Importance Both culture enrichment and next-generation sequencing remain to be time-consuming processes for food testing where rapid methods for pathogen detection are widely available. Our study demonstrated substantial acceleration of the respective process through IMS-MDA and real-time nanopore sequencing. In one example, the combined use of the two methods delivered a less than 24 h turnaround time from a Salmonella-contaminated lettuce sample to phylogenetic identification of the pathogen. Improved efficiency like this is important for further expanding the use of whole genome and metagenomics sequencing in microbial analysis of food. Our results suggest the potential of the quasi metagenomics approach in areas where rapid detection and subtyping of foodborne pathogens is important, such as foodborne outbreak response and precision tracking and monitoring of foodborne pathogens in production environments and supply chains. PMID- 29196296 TI - Environmental Microbiota Drives Microbial Succession and Metabolic Profiles during Chinese Liquor Fermentation. AB - Many microorganisms in environment participate in the fermentation process of Chinese liquor. However, it is unknown what extent of the environmental microbiota influences on fermentation. In this study, high-throughput sequencing combined with multiphasic metabolite target analysis were applied to study the microbial succession and metabolism changes during Chinese liquor fermentation from two environments (old and new workshops). SourceTracker was applied to evaluate the contribution of environmental microbiota to fermentation. Results showed that Daqu contributed 9.10-27.39% of bacterial communities and 61.06 80.00% of fungal communities to fermentation, whereas environments (outdoor ground, indoor ground, tools and other unknown environments) contributed 62.61 90.90% of bacterial communities and 20.00-38.94% of fungal communities to fermentation. In old workshop, six bacteria [Lactobacillus (11.73% average relative abundance), Bacillus (20.78%), Pseudomonas (6.13%), Kroppenstedtia (10.99%), Weissella (16.64%) and Pantoea (3.40%)] and five fungi [Pichia (55.10%), Candida (1.47%), Aspergillus (10.66%), Saccharomycopsis (22.11%) and Wickerhamomyces (3.35%)] were abundant at the beginning of fermentation. However, in new workshop, the change of environmental microbiota decreased the abundances of Bacillus (5.74%), Weissella (6.64%), Pichia (33.91%), Aspergillus (7.08%) and Wickerhamomyces (0.12%), and increased the abundances of Pseudomonas (17.04%), Kroppenstedtia (13.31%), Pantoea (11.41%), Acinetobacter (3.02%), Candida (16.47%) and Kazachstania (1.31%). Meanwhile, in new workshop, the changes of microbial community resulted in the increase of acetic acid, lactic acid, malic acid and ethyl acetate, and the decrease of ethyl lactate during fermentation. This study showed that environmental microbiota was an important source of fermentation microbiota, and could drive both the microbial succession and the metabolic profiles during liquor fermentation.IMPORTANCE Traditional solid-state fermentation of foods and beverages is mainly carried out by complex microbial communities from raw materials, starters and the processing environments. However, it is still unclear how the environmental microbiota influences on the quality of fermented foods and beverages, especially for Chinese liquor. In this study, we utilized high-throughput sequencing, microbial source tracking and multiphasic metabolite target analysis to analyze the origins of microbiota and the metabolic profiles during liquor fermentation. This study contributes to a deeper understanding of the role of environmental microbiota during fermentation. PMID- 29196297 TI - Acetylsalicylic Acid Governs the Effect of Sorafenib in RAS-Mutant Cancers. AB - Purpose: Identify and characterize novel combinations of sorafenib with anti inflammatory painkillers to target difficult-to-treat RAS-mutant cancer.Experimental Design: The cytotoxicity of acetylsalicylic acid (aspirin) in combination with the multikinase inhibitor sorafenib (Nexavar) was assessed in RAS-mutant cell lines in vitro The underlying mechanism for the increased cytotoxicity was investigated using selective inhibitors and shRNA-mediated gene knockdown. In vitro results were confirmed in RAS-mutant xenograft mouse models in vivoResults: The addition of aspirin but not isobutylphenylpropanoic acid (ibruprofen) or celecoxib (Celebrex) significantly increased the in vitro cytotoxicity of sorafenib. Mechanistically, combined exposure resulted in increased BRAF/CRAF dimerization and the simultaneous hyperactivation of the AMPK and ERK pathways. Combining sorafenib with other AMPK activators, such as metformin or A769662, was not sufficient to decrease cell viability due to sole activation of the AMPK pathway. The cytotoxicity of sorafenib and aspirin was blocked by inhibition of the AMPK or ERK pathways through shRNA or via pharmacologic inhibitors of RAF (LY3009120), MEK (trametinib), or AMPK (compound C). The combination was found to be specific for RAS/RAF-mutant cells and had no significant effect in RAS/RAF-wild-type keratinocytes or melanoma cells. In vivo treatment of human xenografts in NSG mice with sorafenib and aspirin significantly reduced tumor volume compared with each single-agent treatment.Conclusions: Combination sorafenib and aspirin exerts cytotoxicity against RAS/RAF-mutant cells by simultaneously affecting two independent pathways and represents a promising novel strategy for the treatment of RAS-mutant cancers.

AB - Clopidogrel acyl glucuronide (CLP-G) is a major phase II metabolite of clopidogrel generated in the liver for further excretion into urine; however, it is unclear whether CLP-G transports from hepatocytes into blood. Because multidrug resistance-associated protein 3 (MRP3) is predominantly expressed in the sinusoidal side of hepatocytes and preferentially transports glucuronide conjugates of drug metabolites from hepatocytes into bloodstream, we hypothesized that MRP3 could be such an efflux transporter for CLP-G. In this study, we compared the liver-to-plasma ratios of clopidogrel and its metabolites (including CLP-G) between Abcc3 (ATP-binding cassette, subfamily C, member 3) knockout (KO) and wild-type (WT) mice. We also evaluated the ATP-dependent uptake of clopidogrel and CLP-G as well as estradiol-17beta-d-glucuronide into human recombinant MRP3 inside-out membrane vesicles in the presence or absence of ATP. The results indicated that the liver-to-plasma ratio of CLP-G was 11-fold higher in KO mice than in WT mice, and that uptake of CLP-G (1 or 10 MUM each) into the membrane vesicles was 11.8- and 3.8-fold higher in the presence of ATP than in the presence of AMP, respectively. We conclude that Mrp3 transports CLP-G from the hepatocytes into blood in an ATP-dependent manner. PMID- 29196298 TI - Risk Assessment in Patients With Diabetes With the TIMI Risk Score for Atherothrombotic Disease. AB - OBJECTIVE: Improved risk assessment for patients with type 2 diabetes and elevated cardiovascular (CV) risk is needed. The Thrombolysis in Myocardial Infarction (TIMI) Risk Score for Secondary Prevention (TRS 2 degrees P) predicts a gradient of risk in patients with prior myocardial infarction (MI) but has not been evaluated in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS: CV event rates were compared by baseline TRS 2 degrees P in 16,488 patients enrolled in SAVOR-TIMI 53 (Saxagliptin Assessment of Vascular Outcomes Recorded in Patients with Diabetes Mellitus-Thrombolysis in Myocardial Infarction 53) with type 2 diabetes and high CV risk or established CV disease. Calibration was tested in the diabetes cohort from the REACH (REduction of Atherothrombosis for Continued Health) Registry. RESULTS: TRS 2 degrees P revealed a robust risk gradient for the composite of CV death, MI, and ischemic stroke in the full trial population, with 2-year event rates of 0.9% in the lowest- and 19.8% in the highest-risk groups (Ptrend < 0.001). A clear risk gradient was present within the subgroups of all coronary artery disease (CAD), CAD without prior MI, CAD with prior MI, peripheral artery disease, and prior stroke (Ptrend < 0.001 for each), with consistent risk relationships across subgroups. The C-statistic (0.71 for CV death and 0.66 for the composite end point) was consistent in each subgroup. There was close calibration with the type 2 diabetes cohort from the REACH Registry (goodness-of-fit P = 0.78). CONCLUSIONS: The expanded TRS 2 degrees P provides a practical and well-calibrated risk prediction tool for patients with type 2 diabetes. PMID- 29196301 TI - Interobserver agreement of various thyroid imaging reporting and data systems. AB - Ultrasonography is the best available tool for the initial work-up of thyroid nodules. Substantial interobserver variability has been documented in the recognition and reporting of some of the lesion characteristics. A number of classification systems have been developed to estimate the likelihood of malignancy: several of them have been endorsed by scientific societies, but their reproducibility is yet to be assessed. We evaluated the interobserver variability of the AACE/ACE/AME, ACR, ATA, EU-TIRADS and K-TIRADS classification systems and the interobserver concordance in the indication to FNA biopsy. Two raters independently evaluated 1055 ultrasound images of thyroid nodules identified in 265 patients at multiple time points, in two separate sets (501 and 554 images). After the first set of nodules, a joint reading was performed to reach a consensus in the feature definitions. The interobserver agreement (Krippendorff alpha) in the first set of nodules was 0.47, 0.49, 0.49, 0.61 and 0.53, for AACE/ACE/AME, ACR, ATA, EU-TIRADS and K-TIRADS systems, respectively. The agreement for the indication to biopsy was substantial to near-perfect, being 0.73, 0.61, 0.75, 0.68 and 0.82, respectively (Cohen's kappa). For all systems, agreement on the nodules of the second set increased. Despite the wide variability in the description of single ultrasonographic features, the classification systems may improve the interobserver agreement that further ameliorates after a specific training. When selecting nodules to be submitted to FNA biopsy, that is main purpose of these classifications, the interobserver agreement is substantial to almost perfect. PMID- 29196300 TI - Mettl3 Mutation Disrupts Gamete Maturation and Reduces Fertility in Zebrafish. AB - N6-methyladenosine (m6A), catalyzed by Mettl3 methyltransferase, is a highly conserved epigenetic modification in eukaryotic messenger RNA (mRNA). Previous studies have implicated m6A modification in multiple biological processes, but the in vivo function of m6A has been difficult to study, because mettl3 mutants are embryonic lethal in both mammals and plants. In this study, we have used transcription activator-like effector nucleases and generated viable zygotic mettl3 mutant, Zmettl3m/m , in zebrafish. We find that the oocytes in Zmettl3m/m adult females are stalled in early development and the ratio of full-grown stage (FG) follicles is significantly lower than that of wild type. Human chorionic gonadotropin-induced ovarian germinal vesicle breakdown in vitro and the numbers of eggs ovulated in vivo are both decreased as well, while the defects of oocyte maturation can be rescued by sex hormone in vitro and in vivo In Zmettl3m/m adult males, we find defects in sperm maturation and sperm motility is significantly reduced. Further study shows that 11-ketotestosterone (11-KT) and 17beta estradiol (E2) levels are significantly decreased in Zmettl3m/m , and defective gamete maturation is accompanied by decreased overall m6A modification levels and disrupted expression of genes critical for sex hormone synthesis and gonadotropin signaling in Zmettl3m/m Thus, our study provides the first in vivo evidence that loss of Mettl3 leads to failed gamete maturation and significantly reduced fertility in zebrafish. Mettl3 and m6A modifications are essential for optimal reproduction in vertebrates. PMID- 29196303 TI - Whole chromosome loss and associated breakage-fusion-bridge cycles transform mouse tetraploid cells. AB - Whole chromosome gains or losses (aneuploidy) are a hallmark of ~70% of human tumors. Modeling the consequences of aneuploidy has relied on perturbing spindle assembly checkpoint (SAC) components, but interpretations of these experiments are clouded by the multiple functions of these proteins. Here, we used a Cre recombinase-mediated chromosome loss strategy to individually delete mouse chromosomes 9, 10, 12, or 14 in tetraploid immortalized murine embryonic fibroblasts. This methodology also involves the generation of a dicentric chromosome intermediate, which subsequently undergoes a series of breakage-fusion bridge (BFB) cycles. While the aneuploid cells generally display a growth disadvantage in vitro, they grow significantly better in low adherence sphere forming conditions and three of the four lines are transformed in vivo, forming large and invasive tumors in immunocompromised mice. The aneuploid cells display increased chromosomal instability and DNA damage, a mutator phenotype associated with tumorigenesis in vivo Thus, these studies demonstrate a causative role for whole chromosome loss and the associated BFB-mediated instability in tumorigenesis and may shed light on the early consequences of aneuploidy in mammalian cells. PMID- 29196304 TI - Long-Term Clinical Outcomes after Early Initiation of RRT in Critically Ill Patients with AKI. AB - Whether earlier initiation of RRT in critically ill patients with AKI can improve outcomes remains debated. We examined follow-up data from a large clinical trial to prospectively investigate the long-term outcomes associated with the timing of RRT initiation in such patients. We extended the follow-up of patients in the Early Versus Delayed Initiation of RRT in Critically Ill Patients with AKI (ELAIN) Trial from 90 days to 1 year after randomization for 230 (99.6%) patients. The primary outcome was a composite of major adverse kidney events (persistent renal dysfunction, dialysis dependence, and mortality) at 1 year. Secondary outcomes included inflammatory markers. Overall, 72 of 111 (64.9%) and 106 of 119 (89.1%) patients met the primary outcome in the early (stage 2 AKI) and delayed (stage 3 AKI) initiation groups, respectively (odds ratio [OR] with early initiation, 0.23; 95% confidence interval [95% CI], 0.11 to 0.45; P< 0.001). The early initiation group had a 1-year all-cause mortality rate (56 of 111 [50.2%]) significantly lower than that of the delayed initiation group (83 of 119 [69.8%]; absolute difference, -19.6%; 95% CI, -32.0% to -7.2%; P<0.01). After 1 year, 16 of 55 (29.1%) and 23 of 36 (63.9%) surviving patients in the early and delayed groups, respectively, failed to recover renal function (absolute difference, -34.8%; 95% CI, -54.6% to -15.0%; P=0.001). In conclusion, early initiation of RRT in these critically ill patients with AKI significantly reduced the occurrence of major adverse kidney events, reduced mortality, and enhanced renal recovery at 1 year. PMID- 29196305 TI - Multiple simultaneous infections in a patient with well-controlled HIV: when Occam's razor fails. AB - Multiple concurrent infectious processes have previously been reported in the context of advanced HIV with significant immunosuppression. Here we report a case of multiple infections in a 56-year-old man with well-controlled HIV diagnosed 5 years earlier. Soon after returning to Australia following 12 years living in Thailand, he became unwell with fevers, night sweats, arthralgia and myalgia. There were no localising symptoms and examination was unremarkable. Investigations revealed positive syphilis (Treponema pallidum) serology with an RPR of 16, a positive urine culture (Klebsiella pneumoniae), a pulmonary nodule, a liver abscess and colitis (Entamoeba histolytica). Recovery was only complete when all the individual infections were treated. PMID- 29196306 TI - Perinatal infratentorial haemorrhage: a rare but possibly life-threatening condition. AB - BACKGROUND: Perinatal infratentorial haemorrhage (PIH) is a rare birth complication associated with abnormal labour. CASE PRESENTATION: A baby boy was born by vacuum extraction at 41 weeks' gestational age. The pregnancy was uneventful and Apgar scores were 3/6/9. Following initial resuscitation, insufficient and irregular breathing, non-reactive pupils and absence of spontaneous movements were noted. A diagnosis of perinatal asphyxia with hypoxic ischaemic encephalopathy (HIE) was considered. Therapeutic hypothermia (TH) for 72 hours was initiated. Cerebral ultrasound showed only a mildly hyperechogenic periventricular substance. A brain MRI on the fourth day of life revealed a subdural haemorrhage in the posterior fossa with compression of the fourth ventricle. CONCLUSION: PIH is an important differential diagnosis to HIE that can be missed with ultrasound. PIH is a treatable condition but may be aggravated by TH. Therefore, in neonates at risk for PIH, a more detailed ultrasound protocol or brain MRI should be considered early. PMID- 29196307 TI - Methotrexate-associated lymphoproliferative disease with multiple pulmonary nodules in a patient with rheumatoid arthritis. AB - A 62-year-old woman with rheumatoid arthritis and secondary Sjogren's syndrome took methotrexate (MTX) 5 mg three times a week regularly but gradually developed an intermittent fever, oral ulcers and productive cough with mucopurulent sputum for about 2 weeks. Image study found multiple nodular lesions and lymphadenopathies in bilateral lungs. Empirical antibiotics for 1 week failed to alleviate the fever. A transbronchial biopsy in the right fourth bronchus showed infiltration of abnormally enlarged lymphoid cells with a surface marker of CD20, some of which also stained positively in situ with Epstein-Barr virus-encoded small RNA and some CD3(+) cells. After a diagnosis of MTX-associated lymphoproliferative disease had been made, MTX was discontinued immediately and intravenous methylprednisolone 125 mg/day was given for 1 week. The clinical condition improved dramatically within 1 month and there was no recurrence after 3-year follow-up. PMID- 29196308 TI - Pseudohyponatraemia secondary to hyperlipidaemia in obstructive jaundice. AB - A 44-year-old man with uncontrolled diabetes and chronic pancreatitis presented with abdominal pain, jaundice and unintentional weight loss. Laboratory investigations were significant for hyponatraemia, an obstructive pattern of liver enzymes. Imaging was consistent with intrahepatic and extrahepatic biliary obstruction, and endoscopic evaluation revealed a long common bile duct stricture. Intravascular volume depletion, beer potomania and syndrome of inappropriate antidiuretic hormone (with concern for biliary or pancreatic malignancy) were considered in the work-up for the aetiology of the hyponatraemia. After 4 days of conventional treatment, hyponatraemia persisted. Lipid panel obtained revealed very high levels of total cholesterol. The patient underwent a successful biliary diversion and reconstruction surgery. Follow-up after 3 months showed a clinically stable patient with resolution of elevated liver enzymes, hyperlipidaemia and hyponatraemia. We illustrate this rare case of hyponatraemia secondary to hyperlipidaemia in obstructive biliary cholestasis. It is important for physicians to thoroughly investigate the aetiology of hyponatraemia at its onset. PMID- 29196309 TI - Low-energy atypical femoral shaft and ipsilateral neck fracture: a rare association. AB - This reports a case of a low-energy ipsilateral femoral shaft and neck fracture in a 69-year-old woman with vitamin D deficiency, who was taking long-term steroids and bisphosphonates. This is a fracture more commonly associated with a high-energy trauma. However, with an ageing global population and an increasing prevalence of bone insufficiency, we predict the incidence of this presentation to increase. Long-term bisphosphonate therapy has been associated with bone insufficiency and an increased rate of delayed union, adding to the complexity of management in these patients. There is currently no consensus regarding the choice of optimal implant or fixation technique to treat this challenging fracture pattern. We discuss the considerations that led to our management approach of a non-overlapping dynamic hip screw and femoral shaft plate construct which achieved uneventful bone healing and a good functional outcome within the first year of follow-up.

AB - Spontaneous retroperitoneal haematoma (SRH) can be a life-threatening emergency presenting with hypovolaemic shock. SRH has been rarely reported with May-Thurner syndrome (MTS) where it occurs due to rupture of the iliac vein or venous collaterals. We report a case of MTS that presented with deep venous thrombosis of the left lower limb complicated by bilateral pulmonary embolism (PE) and a large pelvic haematoma. The simultaneous occurrence of a large pelvic haematoma and PE offered a therapeutic challenge. Successful endovascular management of the case is discussed in this report. PMID- 29196311 TI - Unusual cause of encephalopathy after brain surgery. AB - For patients who have had a recent neurosurgical procedure, a visit to the emergency department for encephalopathy may automatically prompt a neurosurgical consult. We present a case of a patient with a history of Chiari malformation decompressed 6 months prior who presented with a 2-week history of slowly progressive altered mental status, headache and imbalance-symptoms consistent with her initial Chiari symptoms, so neurosurgery was consulted. Imaging showed no acute abnormality, but laboratory results revealed metabolic acidosis with high salicylate levels. When reporting medication use, this patient initially left out that she had been taking Goody's powder (845 mg aspirin) for headaches, and long-term use led to metabolic encephalopathy. Despite a recent history of surgery, it is important to keep the differential diagnosis broad especially when there are signs of metabolic derangement.

PMID- 29196316 TI - Restoring Serotonergic Homeostasis in the Lateral Hypothalamus Rescues Sleep Disturbances Induced by Early-Life Obesity. AB - Early-life obesity predisposes to obesity in adulthood, a condition with broad medical implications including sleep disorders, which can exacerbate metabolic disturbances and disrupt cognitive and affective behaviors. In this study, we examined the long-term impact of transient peripubertal diet-induced obesity (ppDIO, induced between 4 and 10 weeks of age) on sleep-wake behavior in male mice. EEG and EMG recordings revealed that ppDIO increases sleep during the active phase but reduces resting-phase sleep quality. This impaired sleep phenotype persisted for up to 1 year, although animals were returned to a non obesiogenic diet from postnatal week 11 onwards. To better understand the mechanisms responsible for the ppDIO-induced alterations in sleep, we focused on the lateral hypothalamus (LH). Mice exposed to ppDIO did not show altered mRNA expression levels of orexin and melanin-concentrating hormone, two peptides that are important for sleep-wake behavior and food intake. Conversely, the LH of ppDIO-exposed mice had reduced contents of serotonin (5-hydroxytryptamine, 5-HT), a neurotransmitter involved in both sleep-wake and satiety regulation. Interestingly, an acute peripheral injection of the satiety-signaling peptide YY 3-36 increased 5-HT turnover in the LH and ameliorated the ppDIO-induced sleep disturbances, suggesting the therapeutic potential of this peptide. These findings provide new insights into how sleep-wake behavior is programmed during early life and how peripheral and central signals are integrated to coordinate sleep.SIGNIFICANCE STATEMENT Adult physiology and behavior are strongly influenced by dynamic reorganization of the brain during puberty. The present work shows that obesity during puberty leads to persistently dysregulated patterns of sleep and wakefulness by blunting serotonergic signaling in the lateral hypothalamus. It also shows that pharmacological mimicry of satiety with peptide YY3-36 can reverse this neurochemical imbalance and acutely restore sleep composition. These findings add insight into how innate behaviors such as feeding and sleep are integrated and suggest a novel mechanism through which diet-induced obesity during puberty imposes its long-lasting effects on sleep-wake behavior. PMID- 29196315 TI - Phosphorylated CCAAT/Enhancer Binding Protein beta Contributes to Rat HIV-Related Neuropathic Pain: In Vitro and In Vivo Studies. AB - Chronic pain is increasingly recognized as an important comorbidity of HIV infected patients, however, the exact molecular mechanisms of HIV-related pain are still elusive. CCAAT/enhancer binding proteins (C/EBPs) are expressed in various tissues, including the CNS. C/EBPbeta, one of the C/EBPs, is involved in the progression of HIV/AIDS, but the exact role of C/EBPbeta and its upstream factors are not clear in HIV pain state. Here, we used a neuropathic pain model of perineural HIV envelope glycoprotein gp120 application onto the rat sciatic nerve to test the role of phosphorylated C/EBPbeta (pC/EBPbeta) and its upstream pathway in the spinal cord dorsal horn (SCDH). HIV gp120 induced overexpression of pC/EBPbeta in the ipsilateral SCDH compared with contralateral SCDH. Inhibition of C/EBPbeta using siRNA against C/EBPbeta reduced mechanical allodynia. HIV gp120 also increased TNFalpha, TNFRI, mitochondrial superoxide (mtO2.-), and pCREB in the ipsilateral SCDH. ChIP-qPCR assay showed that pCREB enrichment on the C/EBPbeta gene promoter regions in rats with gp120 was higher than that in sham rats. Intrathecal TNF soluble receptor I (functionally blocking TNFalpha bioactivity) or knockdown of TNFRI using antisense oligodeoxynucleotide against TNFRI reduced mechanical allodynia, and decreased mtO2.-, pCREB and pC/EBPbeta. Intrathecal Mito-tempol (a mitochondria-targeted O2.-scavenger) reduced mechanical allodynia and decreased pCREB and pC/EBPbeta. Knockdown of CREB with antisense oligodeoxynucleotide against CREB reduced mechanical allodynia and lowered pC/EBPbeta. These results suggested that the pathway of TNFalpha/TNFRI-mtO2.--pCREB triggers pC/EBPbeta in the HIV gp120-induced neuropathic pain state. Furthermore, we confirmed the pathway using both cultured neurons treated with recombinant TNFalpha in vitro and repeated intrathecal injection of recombinant TNFalpha in naive rats. This finding provides new insights in the understanding of the HIV neuropathic pain mechanisms and treatment.SIGNIFICANCE STATEMENT Painful HIV-associated sensory neuropathy is a neurological complication of HIV infection. Phosphorylated C/EBPbeta (pC/EBPbeta) influences AIDS progression, but it is still not clear about the exact role of pC/EBPbeta and the detailed upstream factors of pC/EBPbeta in HIV-related pain. In a neuropathic pain model of perineural HIV gp120 application onto the sciatic nerve, we found that pC/EBPbeta was triggered by TNFalpha/TNFRI-mtO2.--pCREB signaling pathway. The pathway was confirmed by using cultured neurons treated with recombinant TNFalpha in vitro, and by repeated intrathecal injection of recombinant TNFalpha in naive rats. The present results revealed the functional significance of TNFalpha/TNFRI-mtO2.--pCREB-pC/EBPbeta signaling in HIV neuropathic pain, and should help in the development of more specific treatments for neuropathic pain.

AB - During embryonic development, axons extend over long distances to establish functional connections. In contrast, axon regeneration in the adult mammalian CNS is limited in part by a reduced intrinsic capacity for axon growth. Therefore, insight into the intrinsic control of axon growth may provide new avenues for enhancing CNS regeneration. Here, we performed one of the first miRNome-wide functional miRNA screens to identify miRNAs with robust effects on axon growth. High-content screening identified miR-135a and miR-135b as potent stimulators of axon growth and cortical neuron migration in vitro and in vivo in male and female mice. Intriguingly, both of these developmental effects of miR-135s relied in part on silencing of Kruppel-like factor 4 (KLF4), a well known intrinsic inhibitor of axon growth and regeneration. These results prompted us to test the effect of miR-135s on axon regeneration after injury. Our results show that intravitreal application of miR-135s facilitates retinal ganglion cell (RGC) axon regeneration after optic nerve injury in adult mice in part by repressing KLF4. In contrast, depletion of miR-135s further reduced RGC axon regeneration. Together, these data identify a novel neuronal role for miR-135s and the miR-135 KLF4 pathway and highlight the potential of miRNAs as tools for enhancing CNS axon regeneration.SIGNIFICANCE STATEMENT Axon regeneration in the adult mammalian CNS is limited in part by a reduced intrinsic capacity for axon growth.

PMID- 29196319 TI - Object Representations in Human Visual Cortex Formed Through Temporal Integration of Dynamic Partial Shape Views. AB - We typically recognize visual objects using the spatial layout of their parts, which are present simultaneously on the retina. Therefore, shape extraction is based on integration of the relevant retinal information over space. The lateral occipital complex (LOC) can represent shape faithfully in such conditions. However, integration over time is sometimes required to determine object shape. To study shape extraction through temporal integration of successive partial shape views, we presented human participants (both men and women) with artificial shapes that moved behind a narrow vertical or horizontal slit. Only a tiny fraction of the shape was visible at any instant at the same retinal location. However, observers perceived a coherent whole shape instead of a jumbled pattern. Using fMRI and multivoxel pattern analysis, we searched for brain regions that encode temporally integrated shape identity. We further required that the representation of shape should be invariant to changes in the slit orientation. We show that slit-invariant shape information is most accurate in the LOC. Importantly, the slit-invariant shape representations matched the conventional whole-shape representations assessed during full-image runs. Moreover, when the same slit-dependent shape slivers were shuffled, thereby preventing their spatiotemporal integration, slit-invariant shape information was reduced dramatically. The slit-invariant representation of the various shapes also mirrored the structure of shape perceptual space as assessed by perceptual similarity judgment tests. Therefore, the LOC is likely to mediate temporal integration of slit-dependent shape views, generating a slit-invariant whole shape percept. These findings provide strong evidence for a global encoding of shape in the LOC regardless of integration processes required to generate the shape percept.SIGNIFICANCE STATEMENT Visual objects are recognized through spatial integration of features available simultaneously on the retina. The lateral occipital complex (LOC) represents shape faithfully in such conditions even if the object is partially occluded. However, shape must sometimes be reconstructed over both space and time. Such is the case in anorthoscopic perception, when an object is moving behind a narrow slit. In this scenario, spatial information is limited at any moment so the whole-shape percept can only be inferred by integration of successive shape views over time. We find that LOC carries shape-specific information recovered using such temporal integration processes. The shape representation is invariant to slit orientation and is similar to that evoked by a fully viewed image. Existing models of object recognition lack such capabilities. PMID- 29196318 TI - Inactivation of NMDA Receptors in the Ventral Tegmental Area during Cocaine Self Administration Prevents GluA1 Upregulation but with Paradoxical Increases in Cocaine-Seeking Behavior. AB - Cocaine self-administration increases expression of GluA1 subunits in ventral tegmental area (VTA) dopamine neurons, which subsequently enhance the motivation for cocaine. This increase in GluA1 may be dependent on concomitant NMDA receptor (NMDAR) activation during self-administration, similar to cocaine-induced long term potentiation in the VTA. In this study, we used viral-mediated expression of a dominant-negative GluN1 subunit (HSV-dnGluN1) in VTA neurons to study the effect of transient NMDAR inactivation on the GluA1 increases induced by chronic cocaine self-administration in male rats. We found that dnGluN1 expression in the VTA limited to the 3 weeks of cocaine self-administration prevents the subsequent increase in tissue GluA1 levels when compared with control infusions of HSV-LacZ. Surprisingly, dnGluN1 expression led to an enhancement in the motivation to self administer cocaine as measured using a progressive ratio reinforcement schedule and to enhanced cocaine seeking measured in extinction/reinstatement tests following an extended 3 week withdrawal period. Despite blocking tissue GluA1 increases in cocaine self-administering animals, the HSV-dnGluN1 treatment resulted in increased membrane levels of GluA1 and GluN2B, along with markedly higher locomotor responses to intra-VTA infusions of AMPA, suggesting a paradoxical increase in VTA AMPA receptor responsiveness. Together, these data suggest that NMDARs mediate cocaine-induced increases in VTA GluA1 expression, but such transient NMDAR inactivation also leads to compensatory scaling of synaptic AMPA receptors that enhance the motivational for cocaine.SIGNIFICANCE STATEMENT Dopamine neurons in the ventral tegmental area (VTA) are critical substrates of drug rewards. Animal models indicate that chronic cocaine use enhances excitatory glutamatergic input to these neurons, making them more susceptible to environmental stimuli that trigger drug craving and relapse. We previously found that self-administration of cocaine increases AMPA glutamate receptors in the VTA, and this effect enhances motivation for cocaine. Here we report that the mechanism for this upregulation involves NMDA receptor activity during cocaine use. While interference with NMDA receptor function blocks AMPA receptor upregulation, it also produces a paradoxical enhancement in membrane AMPA receptor subunits, AMPA responsiveness, and the motivation for cocaine. Thus, pharmacotherapy targeting NMDA receptors may inadvertently produce substantial adverse consequences for cocaine addiction. PMID- 29196321 TI - MT3-MMP Promotes Excitatory Synapse Formation by Promoting Nogo-66 Receptor Ectodomain Shedding. AB - Cell-surface molecules are dynamically regulated at the synapse to assemble and disassemble adhesive contacts that are important for synaptogenesis and for tuning synaptic transmission. Metalloproteinases dynamically regulate cellular behaviors through the processing of cell surface molecules. In the present study, we evaluated the role of membrane-type metalloproteinases (MT-MMPs) in excitatory synaptogenesis. We find that MT3-MMP and MT5-MMP are broadly expressed in the mouse cerebral cortex and that MT3-MMP loss-of-function interferes with excitatory synapse development in dissociated cortical neurons and in vivo We identify Nogo-66 receptor (NgR1) as an MT3-MMP substrate that is required for MT3 MMP-dependent synapse formation. Introduction of the shed ectodomain of NgR1 is sufficient to accelerate excitatory synapse formation in dissociated cortical neurons and in vivo Together, our findings support a role for MT3-MMP-dependent shedding of NgR1 in regulating excitatory synapse development.SIGNIFICANCE STATEMENT In this study, we identify MT3-MMP, a membrane-bound zinc protease, to be necessary for the development of excitatory synapses in cortical neurons. We identify Nogo-66 receptors (NgR1) as a downstream target of MT3-MMP proteolytic activity. Furthermore, processing of surface NgR1 by MT3-MMP generates a soluble ectodomain fragment that accelerates the formation of excitatory synapses. We propose that MT3-MMP activity and NgR1 shedding could stimulate circuitry remodeling in the adult brain and enhance functional connectivity after brain injury. PMID- 29196320 TI - Inhibition in Simple Cell Receptive Fields Is Broad and OFF-Subregion Biased. AB - Inhibition in thalamorecipient layer 4 simple cells of primary visual cortex is believed to play important roles in establishing visual response properties and integrating visual inputs across their receptive fields (RFs). Simple cell RFs are characterized by nonoverlapping, spatially restricted subregions in which visual stimuli can either increase or decrease the firing rate of the cell, depending on contrast. Inhibition is believed to be triggered exclusively from visual stimulation of individual RF subregions. However, this view is at odds with the known anatomy of layer 4 interneurons in visual cortex and differs from recent findings in mouse visual cortex. Here we show with in vivo intracellular recordings in cats that while excitation is restricted to RF subregions, inhibition spans the width of simple cell RFs. Consequently, excitatory stimuli within a subregion concomitantly drive excitation and inhibition. Furthermore, we found that the distribution of inhibition across the RF is stronger toward OFF subregions. This inhibitory OFF-subregion bias has a functional consequence on spatial integration of inputs across the RF. A model based on the known anatomy of layer 4 demonstrates that the known proportion and connectivity of inhibitory neurons in layer 4 of primary visual cortex is sufficient to explain broad inhibition with an OFF-subregion bias while generating a variety of phase relations, including antiphase, between excitation and inhibition in response to drifting gratings.SIGNIFICANCE STATEMENT The wiring of excitatory and inhibitory neurons in cortical circuits is key to determining the response properties in sensory cortex. In the visual cortex, the first cells that receive visual input are simple cells in layer 4. The underlying circuitry responsible for the response properties of simple cells is not yet known. In this study, we challenge a long-held view concerning the pattern of inhibitory input and provide results that agree with current known anatomy. We show here that inhibition is evoked broadly across the receptive fields of simple cells, and we identify a surprising bias in inhibition within the receptive field. Our findings represent a step toward a unified view of inhibition across different species and sensory systems. PMID- 29196322 TI - A New, High-Efficacy, Noninvasive Transcranial Electric Stimulation Tuned to Local Neurodynamics. AB - In this paper, we pose the following working hypothesis: in humans, transcranial electric stimulation (tES) with a time course that mimics the endogenous activity of its target is capable of altering the target's excitability. In our case, the target was the primary motor cortex (M1). We identified the endogenous neurodynamics of hand M1's subgroups of pyramidal neuronal pools in each of our subjects by applying Functional Source Separation (FSS) to their EEG recordings. We then tested whether the corticospinal excitability of the hand representation under the above described stimulation, which we named transcranial individual neurodynamics stimulation (tIDS), was higher than in the absence of stimulation (baseline). As a check, we compared tIDS with the most efficient noninvasive facilitatory corticospinal tES known so far, which is 20 Hz transcranial alternating current stimulation (tACS). The control conditions were as follows: (1) sham, (2) transcranial random noise stimulation (tRNS) in the same frequency range as tIDS (1-250 Hz), and (3) a low current tIDS (tIDSlow). Corticospinal excitability was measured with motor-evoked potentials under transcranial magnetic stimulation. The mean motor-evoked potential amplitude increase was 31% of the baseline during tIDS (p < 0.001), and it was 15% during tACS (p = 0.096). tRNS, tIDSlow, and sham induced no effects. Whereas tACS did not produce an enhancement in any subject at the individual level, tIDS was successful in producing an enhancement in 8 of the 16 subjects. The results of the present proof-of-principle study showed that proper exploitation of local neurodynamics can enhance the efficacy of personalized tES.SIGNIFICANCE STATEMENT This study demonstrated that, in humans, transcranial individual neurodynamics stimulation (tIDS), which mimics the endogenous dynamics of the target neuronal pools, effectively changes the excitability of these pools. tIDS holds promise for high efficacy personalized neuromodulations based on individual local neurodynamics. PMID- 29196323 TI - Local Inhibition of PERK Enhances Memory and Reverses Age-Related Deterioration of Cognitive and Neuronal Properties. AB - Protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK) is one of four known kinases that respond to cellular stress by deactivating the eukaryotic initiation factor 2 alpha (eIF2alpha) or other signal transduction cascades. Recently, both eIF2alpha and its kinases were found to play a role in normal and pathological brain function. Here, we show that reduction of either the amount or the activity of PERK, specifically in the CA1 region of the hippocampus in young adult male mice, enhances neuronal excitability and improves cognitive function. In addition, this manipulation rescues the age-dependent cellular phenotype of reduced excitability and memory decline. Specifically, the reduction of PERK expression in the CA1 region of the hippocampus of middle-aged male mice using a viral vector rejuvenates hippocampal function and improves hippocampal-dependent learning. These results delineate a mechanism for behavior and neuronal aging and position PERK as a promising therapeutic target for age-dependent brain malfunction.SIGNIFICANCE STATEMENT We found that local reduced protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK) expression or activity in the hippocampus enhances neuronal excitability and cognitive function in young normal mice, that old CA1 pyramidal cells have reduced excitability and increased PERK expression that can be rescued by reducing PERK expression in the hippocampus, and that reducing PERK expression in the hippocampus of middle-aged mice enhances hippocampal-dependent learning and memory and restores it to normal performance levels of young mice. These findings uncover an entirely new biological link among PERK, neuronal intrinsic properties, aging, and cognitive function. Moreover, our findings propose a new way to fight mild cognitive impairment and aging-related cognitive deterioration.

PMID- 29196327 TI - Oral Health Care Quality Measurement and Its Role in Dental Education. AB - Concerns about health care quality have affected much of the health care delivery system including dentistry and dental education. Believing measurement is the key element in improving quality, the Dental Quality Alliance brought together major stakeholders in oral health care to lead the development of oral health performance measures that can be used to evaluate the performance of dental programs and practices. These measures complement the quality assurance measures dental schools use to ensure compliance with accreditation standards on patient care delivery. This article describes the rationale for and process of developing these performance measures and argues that dental schools should implement quality measurement processes in their clinical programs to improve the clinical practices of the present and better prepare their graduates for their practices of the future. PMID- 29196326 TI - Massachusetts Dental Schools Respond to the Prescription Opioid Crisis: A Statewide Collaboration. AB - The prescription opioid crisis has involved all sectors of U.S. society, affecting every community, socioeconomic group, and age group. While federal and state agencies are actively working to deal with the epidemic, medical and dental providers have been tasked to increase their awareness of the issues and consider ways to safely prescribe opioids and, at the same time, effectively treat their patients' pain. The Commonwealth of Massachusetts, under the leadership of Governor Charles D. Baker and his administration, challenged the state's four medical schools and three dental schools to improve their curricula to prepare the next generation of clinicians to deal with this crisis in an evidence-based, effective, and sympathetic way. This Perspectives article outlines the national prescription opioid crisis, details its effects in Massachusetts, and describes the interdisciplinary collaboration among the Commonwealth, the three dental schools, the Massachusetts Dental Society, and a concerned student group. The article also describes the efforts each dental school is undertaking as well as an assessment of the challenges and limitations in implementing the initiative. The authors hope that the Massachusetts model will be a useful resource for dental schools in other states. PMID- 29196328 TI - An Interprofessional Education and Collaborative Practice Model for Dentistry and Pharmacy. AB - The aims of this study were to evaluate the feasibility of an interprofessional education and collaborative practice model (IECPM) developed by the School of Dentistry (SOD) and College of Pharmacy (COP) for the University of Minnesota dental clinics and to report results of the needs assessment using specific primary care metrics and medication histories gathered through use of the model in 2015-16. Planning focused on establishing a workflow to implement the IECPM by the SOD and COP. The interprofessional team that provided patient care for the study consisted of 50 dental students, ten dental therapy students, one pharmacy student, one pharmacy resident, one faculty pharmacist, one dental assistant, one faculty dental hygienist, and two dentists. The team selected 190 patients in the SOD clinic for the study based on the inclusion criteria: patients with two or more chronic medical conditions who were taking medications. The 190 patients received a comprehensive dental exam, review of social and medical history, and medication therapy management assessment by the interprofessional team. Specific core primary care metrics (blood pressure, pulse, tobacco use, and diabetes status) and identification of drug therapy problems (DTPs) were monitored and/or screened for during the dental visit. The results showed that the IECPM helped identify that this cohort of patients presented with chronic conditions: 64% had hypertension, 34% had diabetes, and 10.5% reported smoking cigarettes. Several DTPs were identified, of which "needs additional drug therapy" was the most common. This cohort was taking multiple medications (2-34 per patient) to address a variety of medical conditions. The study concluded that the IECPM with the SOD and COP helped address a primary care need that often goes unmet in dental clinics. PMID- 29196329 TI - Changing Health Professionals' Attitudes and Practice Behaviors Through Interprofessional Continuing Education in Oral-Systemic Health. AB - Integration of oral-systemic science into clinical care holds promise for improving patient outcomes and presenting opportunities for individuals in various health care professions to learn with, from, and about each other. The aim of this study was to examine whether an interprofessional continuing education program dedicated to oral-systemic health improved participants' attitudes toward interprofessional education and collaboration between dental and non-dental health care professionals and whether it influenced the physicians' practice of screening for debilitating oral diseases. The study took place in 2014 and used a mixed-methods approach, consisting of Readiness for Interprofessional Learning Scale (RIPLS) surveys conducted before, immediately after, and six months after the intervention, as well as surveys of self-reported practice behaviors and semi-structured interviews. A total of 231 health care professionals participated in the lectures and roundtable discussions. Of those, 134 responded to the pre-program survey (58% response rate), 110 responded to the post-program survey (48% response rate), and 58 responded to the survey six months after the program (25% response rate). The participants' median total RIPLS score at baseline was 76.5, which increased significantly immediately following the program (81.0) but returned to baseline six months later (76.5). Participants' RIPLS domain scores also increased significantly by profession from before to after the event, with effects returning to baseline after six months. Significantly more physicians reported screening for caries and periodontal disease after the intervention. An overall theme of "learning with, from, and about each other" was drawn from the interviews with 15 participants. The physicians took away a message of "just look in the mouth," while the dental professionals reported feeling valued as members of the health care team. Although reported improvements in oral-systemic health practice immediately after the intervention were encouraging, further research is necessary to understand why collaborative behaviors were not sustained. PMID- 29196330 TI - Dental Students' Study Habits in Flipped/Blended Classrooms and Their Association with Active Learning Practices. AB - In recognition of the importance for dental education programs to take a student centered approach in which students are encouraged to take responsibility for their learning, a pediatric dentistry course redesign aimed at promoting greater active and self-directed learning was implemented at one U.S. dental school. The aim of this study was to examine the association between the students' self reported study habits and active learning practices necessary for meaningful learning in the flipped/blended classroom. A convenience sample of two classes of second-year dental students in spring 2014 (SP14, n=106) and spring 2015 (SP15, n=106) was invited to participate in the study. Of the SP14 students, 84 participated, for a response rate of 79%; of the SP15 students, 94 participated, for a response rate of 87%. Students' self-reported responses to questions about study strategies with the prerecorded lecture materials and assigned reading materials were examined. Non-parametric analyses resulted in a cohort effect, so data are reported by class. In the SP15 class, 72% reported watching all/more than half of the prerecorded lectures versus 62% of the SP14 class, with a majority watching more than one lecture per week. In the SP15 cohort, 68% used active learning strategies when watching the lectures versus 58.3% of the SP14 cohort. The time of day preferred by the majority of both cohorts for interacting with course materials was 7-11 pm. Both SP14 and SP15 students reported being unlikely to read assigned materials prior to coming to class. Overall, the course redesign appeared to engage students in self-directed active learning. However, the degree to which active learning practices were taking place to achieve meaningful learning was questionable given students' self-reported study strategies. More work is needed to examine strategies for promoting study practices that will lead to meaningful learning. PMID- 29196331 TI - Is Dental Students' Clinical Productivity Associated with Their Personality Profile? AB - The aim of this study was to assess the relationship between personality preferences of incoming fourth-year dental students at the University of Texas Health Science Center at San Antonio as measured by the Keirsey Temperament Sorter II and their third-year clinical productivity and percentage of broken appointments. All 105 incoming fourth-year dental students in 2016 were invited to participate in the study, and 92 students completed the temperament questionnaire, for a response rate of 87.5%. Those students' clinical activity during their third year was measured by production points and percentage of broken appointments extracted from the electronic health record. The results showed that the majority of the respondents were extroverts rather than introverts and that the extroverts had significantly higher production points and significantly fewer broken appointments than the introverts. The most common personality preferences were sensing and judging. More than two-thirds of the respondents represented the Guardian temperament, one of four categories on the temperament measure. These findings help highlight the traits that may contribute to success in clinical training during dental school and support the notion that clinical success may be influenced by certain personality characteristics as well as the technical and specialized skills of dentistry. PMID- 29196332 TI - Correlations Between Final-Year Dental Students' Performance on Knowledge-Based and Clinical Examinations. AB - Dental students are assessed using a range of methods in their final-year examinations. The aim of this study was to explore the correlations and predictive value of final-year dental students' performance on knowledge-based and clinical assessments. Examination data related to applied dental knowledge (ADK), exit case presentation (CP), and integrated structured clinical examination (ISCE) assessments for five consecutive cohorts of final-year students at one U.K. dental school from 2011-12 to 2015-16 were collated. The relationships between the scores produced by each assessment were investigated to explore the relative contributions of each to the understanding of students' abilities across the domains. The study utilized data from all 304 students: 147 (48.4%) females and 157 (51.6%) males. Significant positive correlations were found between ISCE and ADK performance (r(391)=0.42, p<0.001) as well as between ISCE and CP (r(391)=0.44, p<0.001). In addition, both ADK performance and CP performance were significant predictors (at p<0.001) of ISCE performance. This study provides important information about the relationship between these students' performance across knowledge (ADK) and clinical (ISCE and CP) domains and highlights their predictive value. Further research is required to establish if these findings can be generalized and to explore the correlations between performance of dental students before and after graduation. PMID- 29196333 TI - Validity of Peer Evaluation for Team-Based Learning in a Dental School in Japan. AB - The aim of this study was to determine the validity of peer evaluation for team based learning (TBL) classes in dental education in comparison with the term-end examination records and TBL class scores. Examination and TBL class records of 256 third- and fourth-year dental students in six fixed prosthodontics courses from 2013 to 2015 in one dental school in Japan were investigated. Results of the term-end examination during those courses, individual readiness assurance test (IRAT), group readiness assurance test (GRAT), group assignment projects (GAP), and peer evaluation of group members in TBL classes were collected. Significant positive correlations were found between all combinations of peer evaluation, IRAT, and term-end examination. Individual scores also showed a positive correlation with group score (total of GRAT and GAP). From the investigation of the correlations in the six courses, significant positive correlations between peer evaluation and individual score were found in four of the six courses. In this study, peer evaluation seemed to be a valid index for learning performance in TBL classes. To verify the effectiveness of peer evaluation, all students have to realize the significance of scoring the team member's performance. Clear criteria and detailed instruction for appropriate evaluation are also required. PMID- 29196334 TI - Grading Class I Preparations in Preclinical Dental Education: E4D Compare Software vs. the Traditional Standard. AB - The aim of this study was to compare the effectiveness of a novel assessment software system with the traditional grading protocol used in the University of Texas School of Dentistry at Houston operative dentistry preclinical curriculum. In the study, conducted in 2016, 98 Class I preparations were evaluated both traditionally and digitally by two teams of calibrated preclinical faculty members (two evaluators for each team). Scores from each faculty pair were averaged for the traditional and the digital grading systems, and the scores for the two grading systems were compared. The analysis found no significant difference between the two grading systems with respect to isthmus width (p=0.073) and remaining marginal ridge (p=0.5841), but there was a significant difference with respect to pulpal floor depth assessment (p<0.0001). The data suggested that both grading techniques can be used with repeatable confidence for two out of three grading criteria: isthmus width and remaining marginal ridge. In addition, the software offers a self-assessment tool for students to perfect their psychomotor skills while promoting independence and immediate feedback. PMID- 29196335 TI - An Instrument to Assess Dental Students' Competence in Shared Decision Making: A Pilot Study. AB - Evidence suggests that involving patients in health care decisions has a positive impact on health care outcomes and patients' perception of quality. However, the extent to which dental students are trained in communication and shared decision making (SDM) differs, and studies have identified a need for intensified learning and assessment of this competence. A need to more clearly define and operationalize what it means to be proficient in this area has been identified. The aim of this study was to operationalize communicative and relational skills in a comprehensive assessment instrument for SDM. Relevant skills in information exchange, negotiation, communication, and relationship-building were identified through an extensive review of previous research and instruments for assessing communication competence. Indicators for assessing these skills were formulated. The instrument was submitted to a pilot test in 2016 and evaluated on test content, internal structure, and response processes. The Assessment of Shared Decision Making (ASDM) instrument consists of 18 items addressing various aspects of the construct and three types of skills. Findings suggest that the ASDM represents a valid measure of SDM with three major components. The importance of developing the ASDM lies both in the summative assessment of students' communication with patients and for formative assessment purposes. Once identified, the components essential for SDM can be woven into the curriculum and shared with students. Thus, the ASDM provides a structure that can meet the need for intensified learning and assessment of dental students' competence in communication and SDM. PMID- 29196339 TI - Intra-abdominal infection combined with intra-abdominal hypertension aggravates the intestinal mucosal barrier dysfunction. AB - Some patients with intra-abdominal infection (IAI) may develop intra-abdominal hypertension (IAH) during treatment. The present study investigated the impact of IAI combined with IAH on the intestinal mucosal barrier in a rabbit model. Forty eight New Zealand white rabbits were randomly divided into four groups: (i) IAI and IAH; (ii) IAI alone; (iii) IAH alone; and (iv) Control group. IAI model: cecal ligation and puncture for 48 h; IAH model: raised intra-abdominal pressure (IAP) of 20 mmHg for 4 h. Pathological changes in intestinal mucosa were confirmed by light and scanning electron microscopy. FITC-conjugated dextran (FITC-dextran) by gavage was used to measure intestinal mucosal permeability in plasma. Endotoxin, d-Lactate, and diamine oxidase (DAO) in plasma were measured to determine intestinal mucosal damage. Malonaldehyde (MDA), superoxide dismutase (SOD), and GSH in ileum tissues were measured to evaluate intestinal mucosal oxidation and reducing state. Histopathologic scores were significantly higher in the IAI and IAH group, followed by IAI alone, IAH alone, and the control group. FITC-dextran, d-Lactate, DAO, and endotoxin in plasma and MDA in ileum tissues had similar trends. GSH and SOD were significantly lowest the in IAI and IAH group. Occludin levels were lowest in the ileums of the IAI and IAH group. All differences were statistically significant (P-values <0.001). IAI combined with IAH aggravates damage of the intestinal mucosal barrier in a rabbit model. The combined effects were significantly more severe compared with a single factor. IAI combined with IAH should be prevented and treated effectively. PMID- 29196338 TI - Proteomics and metabolomics identify molecular mechanisms of aging potentially predisposing for chronic lymphocytic leukemia. AB - B cell chronic lymphocytic leukemia (B-CLL), the most common type of leukemia in adults, is still essentially incurable despite the development of novel therapeutic strategies. This reflects the incomplete understanding of the pathophysiology of this disease. A comprehensive proteome analysis of primary human B-CLL cells and B cells from younger as well as elderly healthy donors was performed. For comparison, the chronic B cell leukemia cell line JVM-13 was also included. A principal component analysis comprising 6,945 proteins separated these four groups, placing B cells of aged-matched controls between those of young donors and B-CLL patients, while identifying JVM-13 as poorly related cells. Mass spectrometric proteomics data have been made fully accessible via ProteomeXchange with identifier PXD006570-PXD006572, PXD006576, PXD006578, and PXD006589-PXD006591. Remarkably, B cells from aged controls displayed significant regulation of proteins related to stress management in mitochondria and ROS stress such as DLAT, FIS1, and NDUFAB1, and DNA repair, including RAD9A, MGMT, and XPA. ROS levels were indeed found significantly increased in B cells but not in T cells or monocytes from aged individuals. These alterations may be relevant for tumorigenesis and were observed similarly in B-CLL cells. In B-CLL cells, some remarkable unique features like the loss of tumor suppressor molecules PNN and JARID2, the stress-related serotonin transporter SLC6A4, and high expression of ZNF207, CCDC88A, PIGR and ID3, otherwise associated with stem cell phenotype, were determined. Alterations of metabolic enzymes were another outstanding feature in comparison to normal B cells, indicating increased beta-oxidation of fatty acids and increased consumption of glutamine. Targeted metabolomics assays corroborated these results. The present findings identify a potential proteome signature for immune senescence in addition to previously unrecognized features of B-CLL cells and suggest that aging may be accompanied by cellular reprogramming functionally relevant for predisposing B cells to transform to B CLL cells. PMID- 29196340 TI - Dynamics of gaps, vegetation, and plant species with and without fire. AB - PREMISE OF THE STUDY: Areas lacking dominant plants, or gaps, can support high diversity and specialist species. Previous chronosequence research in Florida rosemary scrub showed indistinct gap area patterns with fire and the dependence of certain species on gaps. We hypothesized that fire and gap size would affect extinction, colonization, diversity, and vegetation composition. METHODS: In 2011 12, we revisited gaps first sampled in 2003, recording vascular plant and ground lichen occurrence by species, gap area, and burn history. We analyzed gap, vegetation, and species dynamics using linear mixed models, with Florida rosemary scrub patch as a random factor. KEY RESULTS: Gap areas declined quickly during the first 10 yr postfire and then stabilized. Between 2003 and 2011-12, unburned gaps usually remained extant or split, whereas burned gaps usually merged. Unburned gaps tended to shrink, whereas burned gaps became larger. Species richness was positively related to gap area, fire, and their interaction. Over time, richness declined in unburned gaps and increased in burned gaps. Local extinction and colonization of individual species were related to fire between 2003 and 2011-12. In burned gaps, ground lichens disappeared, but many herbaceous species, including those killed by fire, increased occupancy. Colonization of most species was favored by burning, large gaps, or both. CONCLUSIONS: In Florida rosemary scrub, fire and increasing gap size increased species richness and many individual species occurrences, reduced local extinctions, and increased colonizations. Therefore, land management activities that encourage the creation and maintenance of large gaps will promote biodiversity in this system. PMID- 29196341 TI - Vapor pressure deficit predicts epiphyte abundance across an elevational gradient in a tropical montane region. AB - PREMISE OF THE STUDY: Tropical Montane Cloud Forests (TMCFs) are important ecosystems to study and preserve because of their high biodiversity and critical roles in local and regional ecosystem processes. TMCFs may be particularly affected by changes in climate because of the narrow bands of microclimate they occupy and the vulnerability of TMCF species to projected increases in cloud base heights and drought. A comprehensive understanding of the structure and function of TMCFs is lacking and difficult to attain because of variation in topography within and across TMCF sites. This causes large differences in microclimate and forest structure at both large and small scales. METHODS: In this study, we estimated the abundance of the entire epiphyte community in the canopy (bryophytes, herbaceous vascular plants, woody epiphytes, and canopy dead organic matter) in six sites. In each of the sites we installed a complete canopy weather station to link epiphyte abundance to a number of microclimatic parameters. KEY RESULTS: We found significant differences in epiphyte abundance across the sites; epiphyte abundance increased with elevation and leaf wetness, but decreased as vapor pressure deficit (VPD) increased. Epiphyte abundance had the strongest relationship with VPD; there were differences in VPD that could not be explained by elevation alone. CONCLUSIONS: By measuring this proxy of canopy VPD, TMCF researchers will better understand differences in microclimate and plant community composition across TMCF sites. Incorporating such information in comparative studies will allow for more meaningful comparisons across TMCFs and will further conservation and management efforts in this ecosystem. PMID- 29196342 TI - Edaphic history over seedling characters predicts integration and plasticity of integration across geologically variable populations of Arabidopsis thaliana. AB - PREMISE OF THE STUDY: Studies on phenotypic plasticity and plasticity of integration have uncovered functionally linked modules of aboveground traits and seedlings of Arabidopsis thaliana, but we lack details about belowground variation in adult plants. Functional modules can be comprised of additional suites of traits that respond to environmental variation. We assessed whether shoot and root responses to nutrient environments in adult A. thaliana were predictable from seedling traits or population-specific geologic soil characteristics at the site of origin. METHODS: We compared 17 natural accessions from across the native range of A. thaliana using 14-day-old seedlings grown on agar or sand and plants grown to maturity across nutrient treatments in sand. We measured aboveground size, reproduction, timing traits, root length, and root diameter. Edaphic characteristics were obtained from a global-scale dataset and related to field data. KEY RESULTS: We detected significant among-population variation in root traits of seedlings and adults and in plasticity in aboveground and belowground traits of adult plants. Phenotypic integration of roots and shoots varied by population and environment. Relative integration was greater in roots than in shoots, and integration was predicted by edaphic soil history, particularly organic carbon content, whereas seedling traits did not predict later ontogenetic stages. CONCLUSIONS: Soil environment of origin has significant effects on phenotypic plasticity in response to nutrients, and on phenotypic integration of root modules and shoot modules. Root traits varied among populations in reproductively mature individuals, indicating potential for adaptive and integrated functional responses of root systems in annuals.

PMID- 29196344 TI - Differential cardiac hypertrophy and signaling pathways in pressure versus volume overload. AB - Mechanical overload can be classified into pressure overload and volume overload, causing concentric and eccentric cardiac hypertrophy, respectively. Here, we aimed to differentiate the load-mediated signaling pathways involved in pressure versus volume overload cardiac hypertrophy. Pressure or volume overload was imposed on C57BL/6J mice by transverse aortic constriction (TAC) or aortic regurgitation (AR), respectively. After surgery (2 wk), left ventricular structure and function were evaluated by echocardiographic, hemodynamic, and histological analyses. Signaling pathways related to hypertrophy, fibrosis, angiogenesis, and apoptosis were studied by histological analysis, RT-PCR, and Western blot analysis. Although mean wall stress was similar in both TAC and AR mice, systolic wall stress was significantly increased in TAC and diastolic wall stress was mainly elevated in AR. TAC or AR induced concentric or eccentric compensated hypertrophy, respectively. TAC was associated with more significant fibrosis and apoptosis, whereas AR was associated with more significant angiogenesis. MAPK kinase family, beta-arrestin-2, Akt, and Ca2+-related signaling pathways were markedly activated in TAC but mildly upregulated or unchanged in AR. Pressure overload and volume overload induce different phenotypic and molecular adaptations in cardiac hypertrophy. Most load-related signaling pathways assessed in this study predominate in pressure but not volume overload. The stimulus-specific heterogeneity in the signaling pathways requires distinct manipulations for further mechanistic and pharmacological studies. NEW & NOTEWORTHY Using the transverse aortic constriction mouse model and the newly developed aortic regurgitation mouse model, we delineated the prominent differences between concentric and eccentric cardiac hypertrophy on morphological, functional, and molecular levels. Our findings are important for the precise diagnosis and treatment of these two types of cardiac hypertrophy.

PMID- 29196345 TI - Mitoprotection attenuates myocardial vascular impairment in porcine metabolic syndrome. AB - Metabolic syndrome (MetS) leads to cardiac vascular injury, which may reflect in increased retention of endothelial progenitor cells (EPCs). Coronary endothelial cell (EC) mitochondria partly regulate vascular function and structure. We hypothesized that chronic mitoprotection would preserve EC mitochondria and attenuate coronary vascular injury and dysfunction in swine MetS. Pigs were studied after 16 wk of diet-induced MetS, MetS treated for the last 4 wk with the mitochondria-targeted peptide elamipretide (ELAM; 0.1 mg/kg sc once daily), and lean controls ( n = 6 each). Cardiac remodeling and function were assessed in vivo by multidetector-computed tomography (CT), and coronary artery and sinus blood samples were collected. EC mitochondrial density, apoptosis, oxidative stress, endothelial nitric oxide synthase immunoreactivity, myocardial microvascular density (three-dimensional microcomputed tomography), and coronary endothelial function (organ bath) were assessed ex vivo. The number and arteriovenous gradient of CD34+/KDR+ EPCs were calculated by FACS (a negative net gradient indicating EPC retention). MetS and MetS + ELAM pigs developed similar MetS (obesity, hyperlipidemia, insulin resistance, and hypertension). EC mitochondrial density decreased in MetS animals compared with lean animals but normalized in MetS + ELAM animals. ELAM also attenuated EC oxidative stress and apoptosis and improved subendocardial microvascular density. ELAM-induced vasculoprotection was reflected by decreased coronary retention of EPCs. ELAM also partly improved endothelial nitric oxide synthase immunoreactivity, coronary endothelial function, and vessel maturity, whereas myocardial perfusion was unaffected. Chronic mitoprotection improved coronary EC mitochondrial density and decreased vascular remodeling and dysfunction. However, additional mitochondria independent mechanisms likely contribute to MetS-induced cardiac vascular injury. NEW & NOTEWORTHY The present study shows that chronic mitoprotection preserved coronary endothelial cell mitochondria and decreased vascular injury, subendocardial microvascular loss, coronary retention of endothelial progenitor cells, and release of markers of vascular injury. However, myocardial perfusion remained blunted, suggesting that additional mitochondria-independent mechanisms likely contribute to metabolic syndrome-induced cardiac vascular injury. PMID- 29196347 TI - Healthcare worker influenza vaccination and sickness absence - an ecological study. AB - Although Influenza vaccination is recommended for healthcare workers, vaccination rates in UK healthcare workers are only around 50%. We investigated the association between NHS sickness absence rates (using data from Health and Social Care Information Centre quarterly reports), staff vaccination rates and influenza vaccine efficacy (from Public Health England), influenza deaths (from the Office of National Statistics) and staff satisfaction (from www.NHSstaffsurveys.com). Data from 223 healthcare trusts covered approximately 800,000 staff in each of four influenza seasons from 2011; overall staff sickness rate was roughly 4.5%. Annual vaccination rates varied between 44% and 54%. Higher NHS trust vaccination rates were associated with reduced sickness absence (beta = -0.425 [95% CI -0.658 to -0.192], p<0.001). Thus, a 10% increase in vaccination rate would be associated with a 10% fall in sickness absence rate. Influenza vaccination for NHS staff is associated with reduced sickness absence rates. PMID- 29196348 TI - The value of the physical examination in clinical practice: an international survey. AB - A structured online survey was used to establish the views of 2,684 practising clinicians of all ages in multiple countries about the value of the physical examination in the contemporary practice of internal medicine. 70% felt that physical examination was 'almost always valuable' in acute general medical referrals. 66% of trainees felt that they were never observed by a consultant when undertaking physical examination and 31% that consultants never demonstrated their use of the physical examination to them. Auscultation for pulmonary wheezes and crackles were the two signs most likely to be rated as frequently used and useful, with the character of the jugular venous waveform most likely to be rated as -infrequently used and not useful. Physicians in contemporary hospital general medical practice continue to value the contribution of the physical examination to assessment of outpatients and inpatients, but, in the opinion of trainees, teaching and demonstration could be improved. PMID- 29196349 TI - Screening for obstructive sleep apnoea using the STOPBANG questionnaire and the Epworth sleepiness score in patients admitted on the unselected acute medical take in a UK hospital. AB - Obstructive sleep apnoea (OSA), which is often overlooked in patients presenting to primary and secondary care, is an increasingly common comorbidity. The prevalence of OSA has not been studied in the unselected acute medical take. The aim of this study was to screen for the prevalence of undiagnosed OSA using the STOPBANG Questionnaire and the Epworth sleepiness scale (ESS) score in an unselected acute medical take. This was a cross-sectional study in a busy UK general hospital. Patient demographics, comorbidities, ESS and STOPBANG scores on unselected acute medical takes were reviewed and analysed to assess the prevalence of OSA. Of 93 patients screened, more than 50% were obese. The STOPBANG score was >=3 in 73%. The ESS was significantly increased (>=11) in 20%. On multivariate analysis, ESS continued to remain independently associated with the STOPBANG score with a p-value of 0.04. The routine use of the STOPBANG questionnaire followed by an ESS score in those with a score of >=3 may focus evaluation for undetected OSA in the acute medical care setting. PMID- 29196350 TI - Frequency of stepping down antibiotics and nebuliser treatment is lower at weekends compared to weekdays: an observational study. AB - We hypothesised that delays in providing non-urgent medication step-downs at weekends to medical management may be associated with increased length of stay.In a novel use of electronic prescribing data, we analysed emergency admissions from a busy acute medical hospital over 52 weeks from November 2014 to October 2015. The main outcomes of interest were switching from intravenous antibiotics to oral antibiotics and stopping nebulised bronchodilators. The rate of switching from intravenous to oral antibiotics was lower on Saturdays and Sundays compared with weekdays, and the rate of stopping nebulised bronchodilators was similarly lower at weekends (p<0.001). Median length of stay was shorter in those whose antibiotic treatment was stepped down at weekends compared with weekdays (4 days versus 5 days, p<0.001). Reduced medication step-downs at weekends may represent a bottleneck in patient flow. Electronic prescribing data are a valuable resource for future health services research. PMID- 29196351 TI - Barriers and facilitators to HIV testing in people age 50 and above: a systematic review. AB - Approximately 13% of people living with HIV in the UK are unaware of their infection. New diagnoses among people >=50 years is increasing. Unique factors may be associated with testing in this group. This systematic review aims to identify patient and clinician-related barriers/facilitators to HIV testing in people aged >=50 years. A systematic electronic search was conducted. Papers were assessed for eligibility and data from eligible studies were extracted. Barriers/facilitators were grouped, and the number of times they were reported was noted. Because of considerable heterogeneity, a narrative approach has been undertaken to synthesise data. In total, 17 studies were included. Main barriers to testing were low perceived risk and clinicians' preconceptions about older people. Main facilitators were regular use of healthcare services or being offered/encouraged to test by a healthcare provider. Although being encouraged to test was a common facilitator, clinicians' preconceptions about older people was the biggest barrier. This shows a divide between clinicians' preconceptions and patients' expectations, which may impact on testing rates. This review is an important first step in identifying potential barriers/facilitators for further study or to be addressed in the design of future interventions. PMID- 29196353 TI - The lung microbiome in health and disease. AB - The Human Microbiome Project began 10 years ago, leading to a significant growth in understanding of the role the human microbiome plays in health and disease. In this article, we explain with an emphasis on the lung, the origins of microbiome research. We discuss how 16S rRNA gene sequencing became the first major molecular tool to examine the bacterial communities present within the human body. We highlight the pitfalls of molecular-based studies, such as false findings resulting from contamination, and the limitations of 16S rRNA gene sequencing. Knowledge about the lung microbiome has evolved from initial scepticism to the realisation that it might have a significant influence on many illnesses. We also discuss the lung microbiome in the context of disease by giving examples of important respiratory conditions. In addition, we draw attention to the challenges for metagenomic studies of respiratory samples and the importance of systematic bacterial isolation to enable host-microbiome interactions to be understood. We conclude by discussing how knowledge of the lung microbiome impacts current clinical diagnostics. PMID- 29196352 TI - Hearing-impaired young people - a physician's guide . AB - Physicians reading this will have a broad range of in-depth knowledge about their own subspecialty. However, in daily medical practice there are topics of which all physicians should have some knowledge. Those who deal with young people should have some knowledge of the needs of the hearing-impaired population within this group of patients. This article is intended to provide an overview of young people with hearing impairment (HIYP), the challenges they face and what we can do to help them. In this paper, we assume that data published regarding hearing impaired children apply to HIYP from 13 years (the age at which the transition process begins) to 25 years of age (the age at which 'youth' according to the World health Organization and the Education Health Care Plan ends).

As MS can affect any part of the central nervous system, the presentation is often diverse; however, there are key features that can be useful in the clinic. We comment on the diagnostic criteria and review the main subtypes of MS, including clinically isolated syndrome, relapsing remitting MS, secondary progressive MS and primary progressive MS. Although the underlying aetiology of MS is still not known, we summarise those with most evidence of association. Finally, we aim to present treatment strategies for managing the acute relapse, disease-modifying therapies and MS symptoms. This review highlights that progressive MS is an area where there is currently a paucity of available disease modifying treatments and this will be a major focus for future development. PMID- 29196356 TI - The rise of the genome and personalised medicine. AB - Virtually all medical specialties are impacted by genetic disease. Enhanced understanding of the role of genetics in human disease, coupled with rapid advancement in sequencing technology, is transforming the speed of diagnosis for patients and providing increasing opportunities to tailor management. As set out in the Annual report of the Chief Medical Officer 2016: Generation Genome1 and the recent NHS England board paper Creating a genomic medicine service to lay the foundations to deliver personalised interventions and treatments,2 the increasing 'mainstreaming' of genetic testing into routine practice and plans to embed whole genome sequencing in the NHS mean that the profile and importance of genomics is on the rise for many clinicians. This article provides a brief overview of genomics and its current clinical applications, including its contribution to personalised medicine. Physicians will be signposted to key issues that will allow the successful implementation of genomics for rare disease diagnosis and cancer management. PMID- 29196357 TI - An approach to familial lymphoedema. AB - Lymphoedema is the build-up of lymphatic fluid leading to swelling in the tissues. Most commonly it affects the peripheries. Diagnosis is based on clinical assessment and imaging with lymphoscintigraphy. Treatment is supportive with compression garments, massage, good skin hygiene and prompt use of antibiotics to avoid the complication of cellulitis. Most commonly, lymphoedema occurs as a result of damage to the lymphatic system following surgery, trauma, radiation or infection. However, it can be primary, often associated with a genetic defect that causes disruption to the development of the lymphatic system. Common genetic conditions associated with lymphoedema include Turner syndrome and Noonan syndrome; however, there are numerous others that can be classified based on their clinical presentation and associated features. Herein we discuss how to diagnose and classify the known primary lymphoedema conditions and how best to investigate and manage this group of patients.

AB - This article provides an overview of selected genetic skin conditions where multiple inherited cutaneous tumours are a central feature. Skin tumours that arise from skin structures such as hair, sweat glands and sebaceous glands are called skin appendage tumours. These tumours are uncommon, but can have important implications for patient care. Certain appendageal tumours, particularly when multiple lesions are seen, may indicate an underlying genetic condition. These tumours may not display clinical features that allow a secure diagnosis to be made, necessitating biopsy and dermatopathological assessment. Coupled with robust clinical assessment, biopsy findings can guide genetic testing as, increasingly, the causative genes are known for these conditions. Here we review illustrative examples of appendageal tumours and relevant advances made in genetic discovery, and suggest when referral to a geneticist may need to be considered.

AB - Obesity hypoventilation syndrome (OHS) is a condition in which an individual with a body mass index >30 kg/m2 develops daytime alveolar hypoventilation (defined as a resting PaCO2 >45 mmHg) that cannot be attributed to other pathologies. It is a condition with increasing prevalence and rising cost to healthcare systems worldwide. Right heart failure and pulmonary hypertension are well-known complications of this syndrome.

AB - In this case study, we summarise the inpatient investigations and management of a 68-year-old woman with Takotsubo cardiomyopathy secondary to a Varicella zoster encephalitis and the difficulties inherent with making this diagnosis. She presented with evolving cranial nerve neuropathies, which started with a vagal nerve mononeuritis and eventually included left-sided sensorineural hearing loss and a facial nerve palsy. These symptoms were concomitant with a variety of cardiac abnormalities, including fast atrial fibrillation and electrocardiographic changes. We summarise some of the current understanding of Takotsubo cardiomyopathy and the criteria for its diagnosis. Although left ventricular apical ballooning has been described in association with severe infections and states of high stress, we have not seen it reported in association with a Varicella zoster encephalitis.

AB - A nine-week pregnant 33-year-old female presented with sudden-onset right-sided hemiparesis, hemisensory loss, dysarthria and homonymous hemianopia. She was known to have eleven previous miscarriages and used recreational drugs. A CT-head was unremarkable. The patient was subsequently diagnosed with an acute thromboembolic infarct and chose alteplase after counselling. During thrombolysis an ultrasound identified a foetus with no concerning features. A post thrombolysis CT revealed a left-sided posterior cerebral infarct. CT-venography, carotid Doppler, 72-hour Holter monitor, thrombophilia and an autoimmune screen were all normal. A transthoracic echocardiogram demonstrated a mobile intra atrial septum with a patent foramen ovale confirmed on bubble echocardiogram. Three days post-thrombolysis the patient requested a termination of pregnancy. A subsequent transvaginal ultrasound demonstrated a missed miscarriage for which the patient underwent evacuation of retained products of conception. Multidisciplinary care ensured that her sensorimotor deficit resolved grossly with only mild dysarthria and right-hand fine motor incoordination. PMID- 29196366 TI - The application game.

METHODS: There were 109 MRI scans performed on 30 patients who fulfilled the Assessment of Spondyloarthritis international Society inflammatory back pain criteria at baseline and at 4, 8, and 12 weeks. RESULTS: There were 29 patients who completed the study. Only 4 (14%) patients changed from MRI-negative to MRI-positive (all HLA-B27-positive, OR 2.74). Three of 7 (43%) male HLA-B27-positive patients, 1 of 8 (12.5%) HLA-B27 positive female patients, and no HLA-B27-negative patients changed from MRI- negative to -positive. CONCLUSION: Repeat MRI scans within a 12-week period should be considered in HLA-B27-positive males.

AB - OBJECTIVE: To study disease activity in women with juvenile idiopathic arthritis (JIA) during and after pregnancy. There is little previous knowledge about this topic. METHODS: Our study included 135 pregnancies in 114 women with JIA. Disease activity was assessed at 7 timepoints before, throughout, and after pregnancy with the Disease Activity Score-28-C-reactive protein 3 (DAS28-CRP3). Scores assessed at each visit were analyzed in a linear mixed model. The same statistical method was used to study self-reported physical function, pain, and mental health. RESULTS: Almost 80% of the women were in remission or had low disease activity during and after pregnancy. Although disease activity was stable throughout the study period, we found that DAS28 6 weeks postpartum increased significantly compared to the first trimester (2.78 vs 2.51, p = 0.005) and third trimester (2.78 vs 2.56, p = 0.011), respectively. DAS28 decreased significantly between 6 weeks and 12 months postpartum (2.78 vs 2.54, p = 0.014). Self-reported mental health was significantly better 6 weeks postpartum than before pregnancy (Medical Outcomes Study Short Form-36 Mental Health subscale 80.7 vs 76.5, p = 0.039). Self-reported pain was stable. Physical function was significantly worse in the third trimester of pregnancy than postpartum (Modified Health Assessment Questionnaire 0.57 vs 0.39, p < 0.001). CONCLUSION: In women with JIA, disease activity was highest 6 weeks postpartum, but altogether low and stable in the period from planning pregnancy to 1 year after delivery. PMID- 29196381 TI - Sharing Ongoing Care with Primary Care Physicians Opens Up Opportunity for Timelier and Earlier Care by Rheumatologists for Patients with New Inflammatory Polyarthritis. AB - OBJECTIVE: In our region in Quebec, Canada, access to rheumatologists is very limited. Sharing followup of stable patients with their primary care physicians (PCP) could increase access to rheumatologists. In our study, we assessed the feasibility and potential benefits of sharing followup of inflammatory arthritis (IA) patients with their PCP. METHODS: We reviewed the clinical records of 300 patients with peripheral arthritis who presented at our rheumatology outpatient clinic between July and October 2015. We distributed questionnaires to their treating rheumatologist, asking whether a PCP could participate in the followup of the patient and whether there were any factors that would prevent shared followup. We also distributed questionnaires to PCP to assess their level of comfort in participating in the followup care of patients with arthritis. RESULTS: Chart review was completed on 300 patients. There was no treatment modification in 49% of the cases, and 38% of the visits were deemed unnecessary by the attending rheumatologist. We found that 74% of PCP were very interested in sharing the arthritis followup care of their patients. According to PCP, the main barriers to shared followup were treatment with biological agents, active disease, and need for infiltrations. Main organizational barriers were the lack of rheumatologist availability to see patients urgently (46%) and the lack of clear guidelines for the management of IA (58%). CONCLUSION: Up to 38% of peripheral IA visits to a rheumatologist could have been prevented and done by a PCP. In our department, this represented up to 19 followup visits per week that could have been avoided by involving a PCP. PMID- 29196382 TI - Relatedness of Antibodies to Peptides Containing Homocitrulline or Citrulline in Patients with Rheumatoid Arthritis. AB - OBJECTIVE: Antibodies that target citrullinated protein/peptide (ACPA) and homocitrullinated/carbamylated protein/peptide (AHCPA) are associated with rheumatoid arthritis (RA). The relationship between ACPA and AHCPA remains unclear. We examined the expression and cross-reactivity of these antibodies using citrulline- and homocitrulline-containing synthetic peptides, CitJED and HomoCitJED, respectively, which have equal numbers of citrulline or homocitrulline residues on the same peptide backbone. METHODS: Serum from healthy subjects (n = 51) and patients with RA (n = 137), systemic lupus erythematosus (SLE; n = 37), and psoriatic arthritis (PsA; n = 37) were screened for IgG anti CitJED and anti-HomoCitJED antibodies by ELISA. Cross-reactivity of these antibodies was examined by inhibition with various concentrations of CitJED and HomoCitJED. RESULTS: Out of 137 patients with RA, antibodies to CitJED and HomoCitJED were detected in 69 (50%) and 78 (57%), respectively. Anti-CitJED and HomoCitJED antibodies were 77% concordant and their levels were strongly correlated [Spearman correlation coefficient (rs) = 0.6676]. Sera from 25/27 patients (93%) with RA were inhibited by both CitJED and HomoCitJED with equal or higher affinity for the cognate (homologous) peptide. CONCLUSION: Antibodies to CitJED and HomoCitJED frequently occurred in RA, but were not found in SLE or PsA, suggesting that these antibodies are specific to RA. Cross-reactivity between anti-HomoCitJED and anti-CitJED antibodies suggests that ACPA and AHCPA are derived from the same B cell population and both may contribute to the pathogenesis of RA. PMID- 29196384 TI - Trends in Joint Replacement Surgery in Patients with Rheumatoid Arthritis. AB - OBJECTIVE: This study analyzed trends in large total joint arthroplasties (TJA) and in the proportion of these procedures performed on patients with rheumatoid arthritis (RA). METHODS: The US Nationwide Inpatient Sample (2002-2012) was used to identify the incidences of total shoulder (TSA), elbow (TEA), knee (TKA), hip (THA), and ankle (TAA) arthroplasty and the proportion of these performed with coexisting RA. RESULTS: The prevalence of RA among patients with TJA increased 3.0%. The prevalence of RA among cases of TEA and TSA decreased by 50% (p < 0.0001) and 18% (p = 0.0016), respectively; a 38.0% decrease occurred in the prevalence of RA among TAA (p = 0.06); and nonsignificant increases were seen among THA and TKA. The average age difference between RA and non-RA patients undergoing TJA narrowed by 2 years (p < 0.0001). There was a greater reduction in the proportion of TSA, TEA, and TAA groups among women with RA than men with RA. In the TSA and TEA groups, there was a reduction in the proportion of whites with RA, but not blacks. The proportion of privately insured TSA and TAA patients with RA decreased, while patients with RA undergoing TSA, TEA, or TAA who were receiving Medicaid (government medical insurance) remained relatively stable over time. CONCLUSION: The prevalence of RA has decreased among TSA and TEA patients. A nonsignificant decline occurred among TAA patients. The average age of TJA patients with RA is beginning to mirror those without RA. Sex ratios for TSA, TEA, and TAA patients are following a similar pattern. These results may be evidence of the success of modern RA treatment strategies. PMID- 29196383 TI - Opioid Analgesic Use in Patients with Ankylosing Spondylitis: An Analysis of the Prospective Study of Outcomes in an Ankylosing Spondylitis Cohort. AB - OBJECTIVE: Opioid analgesics may be prescribed to ankylosing spondylitis (AS) patients with pain that is unresponsive to antirheumatic treatment. Our study assessed factors associated with opioid usage in AS. METHODS: A prospective cohort of 706 patients with AS meeting modified New York criteria followed at least 2 years underwent comprehensive clinical evaluation of disease activity and functional impairment. These were assessed by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI). Radiographic severity was assessed by the Bath Ankylosing Spondylitis Radiology Index and modified Stokes Ankylosing Spondylitis Scoring System. Medications taken concurrently with opioids, as well as C-reactive protein (CRP) levels and erythrocyte sedimentation rate (ESR), were determined at each study visit, performed every 6 months. Analyses were carried out at baseline, and longitudinal multivariable models were developed to identify factors independently associated with chronic and intermittent opioid usage over time. RESULTS: Factors significantly associated with opioid usage, especially chronic opioid use, included longer disease duration, smoking, lack of exercise, higher disease activity (BASDAI) and functional impairment (BASFI), depression, radiographic severity, and cardiovascular disease. Patients taking opioids were more likely to be using anxiolytic, hypnotic, antidepressant, and muscle relaxant medications. Multivariable analysis underscored the association with smoking, older age, antitumor necrosis factor agent use, and psychoactive drugs, as well as with subjective but not objective determinants of disease activity. CONCLUSION: Opioid usage was more likely to be associated with subjective measures (depression, BASDAI, BASFI) than objective measures (CRP, ESR), suggesting that pain in AS may derive from sources other than spinal inflammation alone. PMID- 29196385 TI - Characteristic and Outcome of Psoriatic Arthritis Patients with Hyperuricemia. AB - OBJECTIVE: To determine the characteristics of patients with psoriatic arthritis (PsA) who have hyperuricemia (HUC) and their outcomes, especially cardiovascular (CVD) and kidney diseases. METHODS: Patients have been followed prospectively at the PsA clinic according to a standard protocol at 6- to 12-month intervals. We defined HUC in men > 450 umol/l or women > 360 umol/l. We matched patients with HUC based on sex and age +/- 5 years with normal uric acid patients. Demographics information and disease characteristics were reviewed. Outcomes of patients with HUC, especially CVD and kidney diseases, were recorded. Conditional logistic regression was performed to determine factors independently associated with HUC in patients with PsA. RESULTS: There were 325 (31.9%) out of 1019 patients with PsA who had HUC. Of these, 318 cases were matched to 318 controls. There were 11 (3.4%) out of 325 patients with HUC who had gout. Patients with HUC had longer disease duration and a higher Psoriasis Area and Severity Index. They had more concurrent comorbidities, including CVD and metabolic diseases, as well as higher prevalence of kidney stones and higher creatinine. Only 1 patient with HUC was treated with allopurinol at first evaluation visit and 7 patients during followup. Over the followup, 163 of the 318 patients had persistent HUC (pHUC) for more than 2 visits. Patients with pHUC developed more myocardial infarction, heart failure, and renal impairment. Multivariate analysis showed an association between pHUC, PsA disease duration, and obesity. CONCLUSION: HUC is common in patients with PsA, especially in those with longer disease duration and obesity. Proper control of HUC and metabolic diseases may play a preventive role in improving PsA outcomes. PMID- 29196388 TI - Outcome and recovery in first-episode psychosis. AB - There is now a good body of evidence about factors that determine outcome and recovery in a first episode of psychosis. However, so far, this is of limited benefit when making predictions at an individual level. Treatment protocols are one size fits all and the recommended duration of medication remains unclear. What is needed is a more sophisticated approach to predicting outcomes and tailoring treatment options to the individual. Removing predisposing factors is an important aspect of this.

PMID- 29196411 TI - Expression of TP53 is associated with the outcome of MCL independent of MIPI and Ki-67 in trials of the European MCL Network. AB - Currently, prediction of time to treatment failure (TTF) and overall survival (OS) in mantle cell lymphoma (MCL) is based on the clinical factors included in the Mantle Cell Lymphoma International Prognostic Index (MIPI), and proliferation is assessed by Ki67. However, TP53 and SOX11 immunohistochemistry might improve risk stratification. We performed SOX11 and TP53 immunohistochemistry on the so far largest published cohort of lymphoma specimens (n = 365). All patients were treated in prospective trials of the European MCL Network. In multivariate analyses, including MIPI and Ki67, SOX11 expression was not associated with TTF, but patients with low SOX11 expression had shorter OS. On the contrary, high TP53 expression was a strong predictor of TTF and inferior OS compared with low TP53 expression in univariate and multivariate analyses adjusting for MIPI score and Ki-67 index (hazard ratio [HR], 2.0; P = .0054 for TTF, and HR, 2.1; P = .068 for OS). In particular, patients with high TP53 expression (>50% positive lymphoma cells) had a shorter TTF and poor OS independent of both MIPI score and Ki-67 index. Thus, TP53 immunohistochemistry is a suitable test for routine diagnostic practice to assess MCL prognosis. PMID- 29196412 TI - A phase 1 trial of vadastuximab talirine as monotherapy in patients with CD33 positive acute myeloid leukemia. AB - Vadastuximab talirine (SGN-CD33A, 33A) is an antibody-drug conjugate consisting of pyrrolobenzodiazepine dimers linked to a monoclonal antibody targeting CD33, which is expressed in the majority of acute myeloid leukemia (AML) patients. This phase 1 study evaluated the safety, pharmacokinetics, and preliminary activity of vadastuximab talirine and determined the recommended monotherapy dose in patients with relapsed or refractory AML. Additional expansion cohorts tested vadastuximab talirine in specific subpopulations of relapsed AML, and in a cohort of older, treatment-naive patients. Patients received vadastuximab talirine IV on day 1 (5 60 ug/kg) or on days 1 and 4 (20 ug/kg) of 21-day cycles. A total of 131 patients (median age, 73 years [range, 26-89 years]) had intermediate I-II (48%) or adverse (34%) risk by European LeukemiaNet classification; 50% of patients had underlying myelodysplasia. Two dose-limiting toxicities (grade 2 pulmonary embolism and grade 4 hypocellular marrow) occurred during dose finding. Most adverse events (AEs) were consistent with myelosuppression; nonhematologic AEs included fatigue, nausea, and diarrhea. The 30-day mortality was 8%. At the recommended monotherapy dose of 40 ug/kg, the complete remission + CRi rate was 28% (5 of 18 patients); 50% of patients who responded achieved minimal residual disease negativity. In patients across dose levels who achieved CR or CRi, the median time to full count recovery was 6.4 weeks for neutrophils (>=1000/uL) and 10.6 weeks for platelets (>=100 * 109/L). Vadastuximab talirine demonstrates activity and a tolerable safety profile as a single agent in patients with AML. The recommended monotherapy dose of vadastuximab talirine is 40 ug/kg. This trial was registered at www.clinicaltrials.gov as # NCT01902329. PMID- 29196413 TI - The fungal snoRNAome. AB - Small nucleolar RNAs (snoRNAs) are essential players in the rRNA biogenesis due to their involvement in the nucleolytic processing of the precursor and the subsequent guidance of nucleoside modifications. Within the kingdom Fungi, merely a few species-specific surveys have explored their snoRNA repertoire. However, the wide range of the snoRNA landscape spanning all major fungal lineages has not been mapped so far, mainly because of missing tools for automatized snoRNA detection and functional analysis. For the first time, we report here a comprehensive inventory of fungal snoRNAs together with a functional analysis and an in-depth investigation of their evolutionary history including innovations, deletions, and target switches. This large-scale analysis, incorporating more than 120 snoRNA families with more than 7700 individual snoRNA sequences, catalogs and clarifies the landscape of fungal snoRNA families, assigns functions to previously orphan snoRNAs, and increases the number of sequences by 450%. We also show that the snoRNAome is subject to ongoing rearrangements and adaptations, e.g., through lineage-specific targets and redundant guiding functions.

AB - Bacteria may play a role in esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC), although evidence is limited to cross-sectional studies. In this study, we examined the relationship of oral microbiota with EAC and ESCC risk in a prospective study nested in two cohorts. Oral bacteria were assessed using 16S rRNA gene sequencing in prediagnostic mouthwash samples from n = 81/160 EAC and n = 25/50 ESCC cases/matched controls. Findings were largely consistent across both cohorts. Metagenome content was predicted using PiCRUST. We examined associations between centered log-ratio transformed taxon or functional pathway abundances and risk using conditional logistic regression adjusting for BMI, smoking, and alcohol. We found the periodontal pathogen Tannerella forsythia to be associated with higher risk of EAC. Furthermore, we found that depletion of the commensal genus Neisseria and the species Streptococcus pneumoniae was associated with lower EAC risk. Bacterial biosynthesis of carotenoids was also associated with protection against EAC. Finally, the abundance of the periodontal pathogen Porphyromonas gingivalis trended with higher risk of ESCC. Overall, our findings have potential implications for the early detection and prevention of EAC and ESCC. Cancer Res; 77(23); 6777-87. (c)2017 AACR. PMID- 29196419 TI - Recurrent Hemobilia Due to Right Hepatic Artery Pseudoaneurysm. AB - Hemobilia is a potentially life-threatening clinical issue, the etiology of which iatrogenesis is playing increasingly more prominent role. Nowadays the most frequent etiology of hemobilia has shifted toward iatrogenesis owing to increasingly more frequent performance of liver procedures, either open or minimally invasive. Here we report a rare case of recurrent hemobilia after transarterial embolization. A man, aged 57 years, presented with Quincke's triad after cholecystectomy. Computed tomography imaging revealed a pseudoaneurysm of the right hepatic artery. Transarterial embolization failed, and hemobilia recurred. The patient underwent open ligation of the right hepatic artery. Transarterial embolization is a definitive treatment of hemobilia due to vascular issues. The choice of embolizing agent is crucial in transarterial embolization. PMID- 29196420 TI - Fibrillary Glomerulonephritis in Primary Sjogren's Syndrome: A Rare Cause of Renal Failure. AB - Renal involvement in primary Sjogren's syndrome (pSS) varies in severity and prevalence. Although previously felt to be uncommon, kidneys can be involved in 25% to 30% of pSS patients. Fibrillary glomerulonephritis (FGN) is a rare primary glomerular disease that can occur in association with another autoimmune condition or malignancy. The diagnosis relies on renal biopsy findings of haphazardly arranged fibrils in all glomerular compartments and distinction from other forms of fibrillary glomerulopathies such as renal amyloidosis and immunotactoid glomerulopathy. FGN responds poorly to immunosuppressive therapy and has a poor prognosis. Here, we describe a case of FGN in a patient with asymptomatic pSS. We describe the diagnostic work-up, clinical course, treatment utilized, and 1-year follow-up. There is one other case in the literature of FGN in a patient with pSS. The rarity of this association and distinction of FGN from other forms of renal involvement in pSS is important as it impacts therapy and prognosis. The case highlights electron microscopy findings in FGN and poor prognosis.

PMID- 29196421 TI - Integrative model of coronary flow in anatomically based vasculature under myogenic, shear, and metabolic regulation. AB - Coronary blood flow is regulated to match the oxygen demand of myocytes in the heart wall. Flow regulation is essential to meet the wide range of cardiac workload. The blood flows through a complex coronary vasculature of elastic vessels having nonlinear wall properties, under transmural heterogeneous myocardial extravascular loading. To date, there is no fully integrative flow analysis that incorporates global and local passive and flow control determinants. Here, we provide an integrative model of coronary flow regulation that considers the realistic asymmetric morphology of the coronary network, the dynamic myocardial loading on the vessels embedded in it, and the combined effects of local myogenic effect, local shear regulation, and conducted metabolic control driven by venous O2 saturation level. The model predicts autoregulation (approximately constant flow over a wide range of coronary perfusion pressures), reduced heterogeneity of regulated flow, and presence of flow reserve, in agreement with experimental observations. Furthermore, the model shows that the metabolic and myogenic regulations play a primary role, whereas shear has a secondary one. Regulation was found to have a significant effect on the flow except under extreme (high and low) inlet pressures and metabolic demand. Novel outcomes of the model are that cyclic myocardial loading on coronary vessels enhances the coronary flow reserve except under low inlet perfusion pressure, increases the pressure range of effective autoregulation, and reduces the network flow in the absence of metabolic regulation. Collectively, these findings demonstrate the utility of the present biophysical model, which can be used to unravel the underlying mechanisms of coronary physiopathology. PMID- 29196426 TI - A Model for Postdoctoral Education That Promotes Minority and Majority Success in the Biomedical Sciences. AB - How does the United States maintain the highest-quality research and teaching in its professional science workforce and ensure that those in this workforce are effectively trained and representative of national demographics? In the pathway to science careers, the postdoctoral stage is formative, providing the experiences that define the independent work of one's first faculty position. It is also a stage in which underrepresented minorities (URMs) disproportionately lose interest in pursuing academic careers in science and, models suggest, a point at which interventions to increase proportions of URMs in such careers could be most effective. We present a mixed-methods, case study analysis from 17 years of the Fellowships in Research and Science Teaching (FIRST) postdoctoral program, to our knowledge the largest and longest continuously running science postdoctoral program in the United States. We demonstrate that FIRST fellows, in sharp contrast to postdocs overall, are inclusive of URMs (50% African American; 70% women) and as or more successful in their fellowships and beyond as a comparison group (measured by publication rate, attainment of employment in academic science careers, and eventual research grant support). Analysis of alumni surveys and focus group discussions reveals that FIRST fellows place highest value on the cohort-driven community and the developmental teaching and research training the program provides. PMID- 29196425 TI - Providing Social Support for Underrepresented Racial and Ethnic Minority PhD Students in the Biomedical Sciences: A Career Coaching Model. AB - Improvement in the proportion of underrepresented racial and ethnic minorities (URMs) in academic positions has been unsatisfactory. Although this is a complex problem, one key issue is that graduate students often rely on research mentors for career-related support, the effectiveness of which can be variable. We present results from a novel academic career "coaching" intervention, one aim of which was to provide supplementary social support for PhD students, particularly those from underrepresented backgrounds. Coaching was delivered both within small groups and on an individual basis, with a diverse group of coaches and students coming from many universities. Coaches were provided with additional diversity training. Ninety-six semistructured interviews with 33 URM students over 3 years were analyzed using a qualitative framework approach. For most of the URM PhD students, coaching provided social support in the form of emotional, informational, and appraisal support. Coaching groups provided a noncompetitive environment and "community of support" within which students were able to learn from one another's experiences and discuss negative and stressful experiences related to their graduate school, lab, or career plans. This coached peer group model is capable of providing the social support that many URM students do not find at their home universities. PMID- 29196427 TI - Development of a Biological Science Quantitative Reasoning Exam (BioSQuaRE). AB - Multiple reports highlight the increasingly quantitative nature of biological research and the need to innovate means to ensure that students acquire quantitative skills. We present a tool to support such innovation. The Biological Science Quantitative Reasoning Exam (BioSQuaRE) is an assessment instrument designed to measure the quantitative skills of undergraduate students within a biological context. The instrument was developed by an interdisciplinary team of educators and aligns with skills included in national reports such as BIO2010, Scientific Foundations for Future Physicians, and Vision and Change Undergraduate biology educators also confirmed the importance of items included in the instrument. The current version of the BioSQuaRE was developed through an iterative process using data from students at 12 postsecondary institutions. A psychometric analysis of these data provides multiple lines of evidence for the validity of inferences made using the instrument. Our results suggest that the BioSQuaRE will prove useful to faculty and departments interested in helping students acquire the quantitative competencies they need to successfully pursue biology, and useful to biology students by communicating the importance of quantitative skills. We invite educators to use the BioSQuaRE at their own institutions. PMID- 29196429 TI - Engaging Undergraduate Biology Students in Scientific Modeling: Analysis of Group Interactions, Sense-Making, and Justification. AB - National calls for improving science education (e.g., Vision and Change) emphasize the need to learn disciplinary core ideas through scientific practices. To address this need, we engaged small groups of students in developing diagrammatic models within two (one large-enrollment and one medium-enrollment) undergraduate introductory biology courses. During these activities, students developed scientific models of biological phenomena such as enhanced growth in genetically modified fish. To investigate whether undergraduate students productively engaged in scientific practices during these modeling activities, we recorded groups of students as they developed models and examined three characteristics: how students 1) interacted with one another, 2) made sense of phenomena, and 3) justified their ideas. Our analysis indicates that students spent most of the time on task, developing and evaluating their models. Moreover, they worked cooperatively to make sense of core ideas and justified their ideas to one another throughout the activities. These results demonstrate that, when provided with the opportunity to develop models during class, students in large enrollment lecture courses can productively engage in scientific practices. We discuss potential reasons for these outcomes and suggest areas of future research to continue advancing knowledge regarding engaging students in scientific practices in large-enrollment lecture courses. PMID- 29196428 TI - Measurement Instrument for Scientific Teaching (MIST): A Tool to Measure the Frequencies of Research-Based Teaching Practices in Undergraduate Science Courses. AB - The Scientific Teaching (ST) pedagogical framework provides various approaches for science instructors to teach in a way that more closely emulates how science is practiced by actively and inclusively engaging students in their own learning and by making instructional decisions based on student performance data. Fully understanding the impact of ST requires having mechanisms to quantify its implementation. While many useful instruments exist to document teaching practices, these instruments only partially align with the range of practices specified by ST, as described in a recently published taxonomy. Here, we describe the development, validation, and implementation of the Measurement Instrument for Scientific Teaching (MIST), a survey derived from the ST taxonomy and designed to gauge the frequencies of ST practices in undergraduate science courses. MIST showed acceptable validity and reliability based on results from 7767 students in 87 courses at nine institutions. We used factor analyses to identify eight subcategories of ST practices and used these categories to develop a short version of the instrument amenable to joint administration with other research instruments. We further discuss how MIST can be used by instructors, departments, researchers, and professional development programs to quantify and track changes in ST practices. PMID- 29196431 TI - Editor's note: shame, stigma and medicine. PMID- 29196430 TI - Aligning Practice to Policies: Changing the Culture to Recognize and Reward Teaching at Research Universities. AB - Recent calls for improvement in undergraduate education within STEM (science, technology, engineering, and mathematics) disciplines are hampered by the methods used to evaluate teaching effectiveness. Faculty members at research universities are commonly assessed and promoted mainly on the basis of research success. To improve the quality of undergraduate teaching across all disciplines, not only STEM fields, requires creating an environment wherein continuous improvement of teaching is valued, assessed, and rewarded at various stages of a faculty member's career. This requires consistent application of policies that reflect well-established best practices for evaluating teaching at the department, college, and university levels. Evidence shows most teaching evaluation practices do not reflect stated policies, even when the policies specifically espouse teaching as a value. Thus, alignment of practice to policy is a major barrier to establishing a culture in which teaching is valued. Situated in the context of current national efforts to improve undergraduate STEM education, including the Association of American Universities Undergraduate STEM Education Initiative, this essay discusses four guiding principles for aligning practice with stated priorities in formal policies: 1) enhancing the role of deans and chairs; 2) effectively using the hiring process; 3) improving communication; and 4) improving the understanding of teaching as a scholarly activity. In addition, three specific examples of efforts to improve the practice of evaluating teaching are presented as examples: 1) Three Bucket Model of merit review at the University of California, Irvine; (2) Evaluation of Teaching Rubric, University of Kansas; and (3) Teaching Quality Framework, University of Colorado, Boulder. These examples provide flexible criteria to holistically evaluate and improve the quality of teaching across the diverse institutions comprising modern higher education.

These highly dynamic structures form an integral component of the cytoskeleton of muscle, brain, and mesenchymal cells. Here, we review the current ideas on the role of type III IFs in health and disease. It turns out that they not only offer resilience to mechanical strains, but, most importantly, they facilitate very efficiently the integration of cell structure and function, thus providing the necessary scaffolds for optimal cellular responses upon biochemical stresses and protecting against cell death, disease, and aging. PMID- 29196435 TI - Leaving the Bench and Finding Your Foundation. AB - Scientists who leave the laboratory bench to work for biomedical foundations mobilize and focus resources on the most promising research behind a foundation's mission. They acquire a broad view of a field, interact closely with research scientists at meetings and laboratory visits, and often manage proposal review boards and monitor grant progress. Increasingly, scientists at foundations also have a more active role in catalyzing research: They are involved in organizing targeted workshops, setting research priorities, and directly creating and managing resources for a scientific community. They often work closely with patient advocacy groups, contract research organizations, government funders and regulators, and biotech and pharmaceutical companies.Job opportunities in foundations are highly varied, reflecting the diversity of foundations and missions. For example, some foundations have general missions to support broad basic scientific research, whereas others focus specifically on a particular disease and may require different skills. Most scientific positions at foundations require a PhD or MD and often some postdoctoral or other experience, although not all do. Foundations often lack the clear career path that an academic position offers (various levels of professorship, tenure, etc.), although there is often significant potential for growth in responsibilities in terms of managing science, people, and budgets.

PMID- 29196436 TI - Vonoprazan prevents low-dose aspirin-associated ulcer recurrence: randomised phase 3 study. AB - OBJECTIVE: Compare efficacy and safety of vonoprazan and lansoprazole for secondary prevention of low-dose aspirin (LDA)-associated peptic ulcers in a 24 week study and long-term extension therapy in separate study. DESIGN: Double blind, randomised, non-inferiority study; single-blind extension study at 104 Japanese sites, including 621 patients (439 in extension) with a history of peptic ulcers who required long-term LDA therapy. Randomised (1:1:1, computer generated) patients received lansoprazole 15 mg (n=217), vonoprazan 10 mg (n=202) or vonoprazan 20 mg (n=202) once daily for 24 weeks (double blind) and <=2 years (extension). The following measurements were made: 24-week (primary outcome; double blind) and 12-week peptic ulcer recurrence rate, 24-week GI bleeding rate, cumulative incidences of peptic ulcer recurrence and GI bleeding, treatment emergent adverse events, laboratory results, serum gastrin and pepsinogen I/II concentrations. RESULTS: The 24-week peptic ulcer recurrence rate was 2.8%, 0.5% and 1.5% in the lansoprazole 15 mg, vonoprazan 10 mg and vonoprazan 20 mg groups, respectively. Vonoprazan was non-inferior (Farrington and Manning test: margin 8.7%, significance level 2.5%) to lansoprazole. In the post hoc analyses of the extension study, peptic ulcer recurrence rates were significantly lower with vonoprazan 10 mg (log-rank test, P=0.039), but not vonoprazan 20 mg (P=0.260), compared with lansoprazole 15 mg. GI bleeding rates were higher with lansoprazole compared with two doses of vonoprazan in both 24-week study and extension study. CONCLUSION: Vonoprazan (10 and 20 mg) was as effective as lansoprazole (15 mg) in preventing peptic ulcer recurrence during LDA therapy, had a similar long-term safety profile and was well tolerated.

PMID- 29196442 TI - Nephron progenitor cell death elicits a limited compensatory response associated with interstitial expansion in the neonatal kidney. AB - The final nephron number in an adult kidney is regulated by nephron progenitor cell availability and collecting duct branching in the fetal period. Fetal environmental perturbations that cause reductions in cell numbers in these two compartments result in low nephron endowment. Previous work has shown that maternal dietary factors influence nephron progenitor cell availability, with both caloric restriction and protein deprivation leading to reduced cell numbers through apoptosis. In this study, we evaluate the consequences of inducing nephron progenitor cell death on progenitor niche dynamics and on nephron endowment. Depletion of approximately 40% of nephron progenitor cells by expression of diphtheria toxin A at embryonic day 15 in the mouse results in 10 20% nephron reduction in the neonatal period. Analysis of cell numbers within the progenitor cell pool following induction of apoptosis reveals a compensatory response in which surviving progenitor cells increase their proliferation and replenish the niche. The proliferative response is temporally associated with infiltration of macrophages into the nephrogenic zone. Colony stimulating factor 1 (CSF1) has a mitogenic effect on nephron progenitor cells, providing a potential explanation for the compensatory proliferation. However, CSF1 also promotes interstitial cell proliferation, and the compensatory response is associated with interstitial expansion in recovering kidneys which can be pharmacologically inhibited by treatment with clodronate liposomes. Our findings suggest that the fetal kidney employs a macrophage-dependent compensatory regenerative mechanism to respond to acute injury caused by death of nephron progenitor cells, but that this regenerative response is associated with neonatal interstitial expansion.

AB - OBJECTIVE: Chemokine pathways are co-opted by pancreatic adenocarcinoma (PDAC) to facilitate myeloid cell recruitment from the bone marrow to establish an immunosuppressive tumour microenvironment (TME). Targeting tumour-associated CXCR2+neutrophils (TAN) or tumour-associated CCR2+ macrophages (TAM) alone improves antitumour immunity in preclinical models. However, a compensatory influx of an alternative myeloid subset may result in a persistent immunosuppressive TME and promote therapeutic resistance. Here, we show CCR2 and CXCR2 combined blockade reduces total tumour-infiltrating myeloids, promoting a more robust antitumour immune response in PDAC compared with either strategy alone. METHODS: Blood, bone marrow and tumours were analysed from PDAC patients and controls. Treatment response and correlative studies were performed in mice with established orthotopic PDAC tumours treated with a small molecule CCR2 inhibitor (CCR2i) and CXCR2 inhibitor (CXCR2i), alone and in combination with chemotherapy. RESULTS: A systemic increase in CXCR2+ TAN correlates with poor prognosis in PDAC, and patients receiving CCR2i showed increased tumour infiltrating CXCR2+ TAN following treatment. In an orthotopic PDAC model, CXCR2 blockade prevented neutrophil mobilisation from the circulation and augmented chemotherapeutic efficacy. However, depletion of either CXCR2+ TAN or CCR2+ TAM resulted in a compensatory response of the alternative myeloid subset, recapitulating human disease. This was overcome by combined CCR2i and CXCR2i, which augmented antitumour immunity and improved response to FOLFIRINOX chemotherapy. CONCLUSION: Dual targeting of CCR2+ TAM and CXCR2+ TAN improves antitumour immunity and chemotherapeutic response in PDAC compared with either strategy alone. PMID- 29196443 TI - Modelling glioblastoma tumour-host cell interactions using adult brain organotypic slice co-culture. AB - Glioblastoma multiforme (GBM) is an aggressive incurable brain cancer. The cells that fuel the growth of tumours resemble neural stem cells found in the developing and adult mammalian forebrain. These are referred to as glioma stem cells (GSCs). Similar to neural stem cells, GSCs exhibit a variety of phenotypic states: dormant, quiescent, proliferative and differentiating. How environmental cues within the brain influence these distinct states is not well understood. Laboratory models of GBM can be generated using either genetically engineered mouse models, or via intracranial transplantation of cultured tumour initiating cells (mouse or human). Unfortunately, these approaches are expensive, time consuming, low-throughput and ill-suited for monitoring live cell behaviours. Here, we explored whole adult brain coronal organotypic slices as an alternative model. Mouse adult brain slices remain viable in a serum-free basal medium for several weeks. GSCs can be easily microinjected into specific anatomical sites ex vivo, and we demonstrate distinct responses of engrafted GSCs to diverse microenvironments in the brain tissue. Within the subependymal zone - one of the adult neural stem cell niches - injected tumour cells could effectively engraft and respond to endothelial niche signals. Tumour-transplanted slices were treated with the antimitotic drug temozolomide as proof of principle of the utility in modelling responses to existing treatments. Engraftment of mouse or human GSCs onto whole brain coronal organotypic brain slices therefore provides a simplified, yet flexible, experimental model. This will help to increase the precision and throughput of modelling GSC-host brain interactions and complements ongoing in vivo studies.

PMID- 29196444 TI - Temporal analysis of hippocampal CA3 gene coexpression networks in a rat model of febrile seizures. AB - Complex febrile seizures during infancy constitute an important risk factor for development of epilepsy. However, little is known about the alterations induced by febrile seizures that make the brain susceptible to epileptic activity. In this context, the use of animal models of hyperthermic seizures (HS) could allow the temporal analysis of brain molecular changes that arise after febrile seizures. Here, we investigated temporal changes in hippocampal gene coexpression networks during the development of rats submitted to HS. Total RNA samples were obtained from the ventral hippocampal CA3 region at four time points after HS at postnatal day (P) 11 and later used for gene expression profiling. Temporal endpoints were selected for investigating the acute (P12), latent (P30 and P60) and chronic (P120) stages of the HS model. A weighted gene coexpression network analysis was used to characterize modules of coexpressed genes, as these modules might contain genes with similar functions. The transcriptome analysis pipeline consisted of building gene coexpression networks, identifying network modules and hubs, performing gene-trait correlations and examining changes in module connectivity. Modules were functionally enriched to identify functions associated with HS. Our data showed that HS induce changes in developmental, cell adhesion and immune pathways, such as Wnt, Hippo, Notch, Jak-Stat and Mapk. Interestingly, modules involved in cell adhesion, neuronal differentiation and synaptic transmission were activated as early as 1 day after HS. These results suggest that HS trigger transcriptional alterations that could lead to persistent neurogenesis, tissue remodeling and inflammation in the CA3 hippocampus, making the brain prone to epileptic activity.

PMID- 29196449 TI - Sustained T follicular helper cell response is essential for control of chronic viral infection. AB - During chronic viral infections, both CD8 and CD4 T cell responses are functionally compromised. Alongside exhaustion of CD8 T cells during chronic viral infections, it has also been documented that the CD4 T cells have an increased propensity to differentiate toward CXCR5+ T follicular helper cell (TFH) lineage. Whether these TFH cells contribute to the immune response to chronic viral infection has remained unclear. Using chronic lymphocytic choriomeningitis virus (LCMV) infection in conjunction with an in vivo system where TFH cells can be conditionally ablated, we have established that these TFH cells do in fact play an important protective function. Specifically, we demonstrate that these TFH cells are essential for the late emergence of neutralizing LCMV-specific antibodies that keep viral titers in check and ultimately allow mice to clear the virus. By supporting the generation of neutralizing antibodies, we show that sustained activity of TFH cells promotes control of the chronic infection in face of exhausted CD8 T cell responses. PMID- 29196451 TI - Late arising T follicular helper cells cultivate the B cell crop during chronic infections. AB - Follicular helper CD4+ T cells are essential for the development of neutralizing antibodies that contain chronic viral infection. PMID- 29196450 TI - Migratory CD11b+ conventional dendritic cells induce T follicular helper cell dependent antibody responses. AB - T follicular helper (Tfh) cells are a subset of CD4+ T cells that promote antibody production during vaccination. Conventional dendritic cells (cDCs) efficiently prime Tfh cells; however, conclusions regarding which cDC instructs Tfh cell differentiation have differed between recent studies. We found that these discrepancies might exist because of the unusual sites used for immunization in murine models, which differentially bias which DC subsets access antigen. We used intranasal immunization as a physiologically relevant route of exposure that delivers antigen to all tissue DC subsets. Using a combination of mice in which the function of individual DC subsets is impaired and different antigen formulations, we determined that CD11b+ migratory type 2 cDCs (cDC2s) are necessary and sufficient for Tfh induction. DC-specific deletion of the guanine nucleotide exchange factor DOCK8 resulted in an isolated loss of CD11b+ cDC2, but not CD103+ cDC1, migration to lung-draining lymph nodes. Impaired cDC2 migration or development in DC-specific Dock8 or Irf4 knockout mice, respectively, led to reduced Tfh cell priming, whereas loss of CD103+ cDC1s in Batf3-/- mice did not. Loss of cDC2-dependent Tfh cell priming impaired antibody-mediated protection from live influenza virus challenge. We show that migratory cDC2s uniquely carry antigen into the subanatomic regions of the lymph node where Tfh cell priming occurs-the T-B border. This work identifies the DC subset responsible for Tfh cell-dependent antibody responses, particularly when antigen dose is limiting or is encountered at a mucosal site, which could ultimately inform the formulation and delivery of vaccines.

PMID- 29196453 TI - Physician Preferences Surrounding Urinary Tract Infection Management in Neonates. AB - OBJECTIVES: Variability exists in the treatment of neonates with urinary tract infection (UTI), potentially reflecting an overuse of resources. A cross sectional vignette survey was designed to examine variability in physician preferences for intravenous (IV) antibiotic duration, genitourinary imaging, and prophylactic antibiotics and to evaluate drivers of resource use. METHODS: The survey was administered to a random sample of pediatricians through the American Medical Association's Physician Masterfile. Respondents were provided with a case vignette of a 2-week-old neonate with a febrile UTI and asked to indicate preferences for IV antibiotic duration and rank drivers of this decision. Respondents were also asked whether they would obtain a voiding cystourethrogram (VCUG) and, regardless of preference, randomly presented with a normal result or bilateral grade II vesicoureteral reflux. The survey was delivered electronically to facilitate skip logic and randomization. RESULTS: A total of 279 surveys were completed. Preference for total IV antibiotic duration differed significantly (P < .001) across specialty, with a median duration of 2 days for general pediatricians/hospitalists, 7 days for neonatologists, and 5 days for infectious disease pediatricians. For the 47% (n = 131) who did not want a VCUG, 24/61 (39%) wanted prophylactic antibiotics when presented with grade II vesicoureteral reflux (P < .001). CONCLUSIONS: Subspecialty status appeared to be the most influential driver of IV antibiotic duration in the treatment of UTI. A substantial proportion of pediatricians who initially expressed a preference against ordering a VCUG wished to prescribe prophylactic antibiotics when results were abnormal, which suggests that even unwanted diagnostic test results drive treatment decisions.

PMID- 29196456 TI - Deep Coverage Tissue and Cellular Proteomics Revealed IL-1beta Can Independently Induce the Secretion of TNF-Associated Proteins from Human Synoviocytes. AB - Synovitis is a key contributor to the inflammatory environment in osteoarthritis (OA) joints. Currently, the biological therapy of OA is not satisfactory in multiple single-target trials on anti-TNF agents, or IL-1 antagonists. Systems biological understanding of the phosphorylation state in OA synovium is warranted to direct further therapeutic strategies. Therefore, in this study, we compared the human synovial phosphoproteome of the OA with the acute joint fracture subjects. We found that OA synovium had significantly more phosphoproteins, and 82 phosphoproteins could only be specifically found in all the OA samples. Differentially expressed proteins of the OA synovium were focusing on endoplasmic reticulum-/Golgi-associated secretion and negative regulation of cell proliferation, which was verified through an IL-1beta-treated human synoviocyte (HS) in vitro model. With data-independent acquisition-based mass spectrometry, we found that IL-1beta could induce HS to secrete proteins that were significantly associated with the endosomal/vacuolar pathway, endoplasmic reticulum/Golgi secretion, complement activation, and collagen degradation. Especially, we found that while specifically suppressing HS endocytosis, IL-1beta could activate the secretion of 25 TNF-associated proteins, and the change of SERPINE2 and COL3A1 secretion was verified by immunoblotting. In conclusion, our results suggest that OA synovium has a polarized phosphoproteome to inhibit proliferation and maintain active secretion of HS, whereas IL-1beta alone can transform HS to produce a synovitis-associated secretome, containing numerous TNF associated secretory proteins in a TNF-independent mode. PMID- 29196457 TI - A High-Throughput Real-Time Imaging Technique To Quantify NETosis and Distinguish Mechanisms of Cell Death in Human Neutrophils. AB - Neutrophils play a key role in host defenses and have recently been implicated in the pathogenesis of autoimmune diseases by various mechanisms, including formation of neutrophil extracellular traps through a recently described distinct form of programmed cell death called NETosis. Techniques to assess and quantitate NETosis in an unbiased, reproducible, and efficient way are lacking, considerably limiting the advancement of research in this field. We optimized and validated, a new method to automatically quantify the percentage of neutrophils undergoing NETosis in real time using the IncuCyte ZOOM imaging platform and the membrane permeability properties of two DNA dyes. Neutrophils undergoing NETosis induced by various physiological stimuli showed distinct changes, with a loss of multilobulated nuclei, as well as nuclear decondensation followed by membrane compromise, and were accurately counted by applying filters based on fluorescence intensity and nuclear size. Findings were confirmed and validated with the established method of immunofluorescence microscopy. The platform was also validated to rapidly assess and quantify the dose-dependent effect of inhibitors of NETosis. In addition, this method was able to distinguish among neutrophils undergoing NETosis, apoptosis, or necrosis based on distinct changes in nuclear morphology and membrane integrity. The IncuCyte ZOOM platform is a novel real time assay that quantifies NETosis in a rapid, automated, and reproducible way, significantly optimizing the study of neutrophils. This platform is a powerful tool to assess neutrophil physiology and NETosis, as well as to swiftly develop and test novel neutrophil targets. PMID- 29196458 TI - Integrin alpha4beta7 Blockade Preferentially Impacts CCR6+ Lymphocyte Subsets in Blood and Mucosal Tissues of Naive Rhesus Macaques. AB - Infusion of a simianized anti-alpha4beta7 mAb (Rh-alpha4beta7) just before and following SIV infection protected rhesus macaques from developing AIDS and partially from vaginal SIV acquisition. Recently, short-term treatment with Rh alpha4beta7 in combination with cART was found to lead to prolonged viral suppression after withdrawal of all therapeutic interventions. The humanized form of Rh-alpha4beta7, vedolizumab, is a highly effective treatment for inflammatory bowel disease. To clarify the mechanism of action of Rh-alpha4beta7, naive macaques were infused with Rh-alpha4beta7 and sampled in blood and tissues before and after treatment to monitor several immune cell subsets. In blood, Rh alpha4beta7 increased the CD4+ and CD8+ T cell counts, but not B cell counts, and preferentially increased CCR6+ subsets while decreasing CD103+ and CD69+ lymphocytes. In mucosal tissues, surprisingly, Rh-alpha4beta7 did not impact integrin alpha4+ cells, but decreased the frequencies of CCR6+ and CD69+ CD4+ T cells and, in the gut, Rh-alpha4beta7 transiently decreased the frequency of memory and IgA+ B cells. In summary, even in the absence of inflammation, Rh alpha4beta7 impacted selected immune cell subsets in different tissues. These data provide new insights into the mechanisms by which Rh-alpha4beta7 may mediate its effect in SIV-infected macaques with implications for understanding the effect of treatment with vedolizumab in patients with inflammatory bowel disease. PMID- 29196459 TI - Role of CD44 in Regulating TLR2 Activation of Human Macrophages and Downstream Expression of Proinflammatory Cytokines. AB - Osteoarthritis (OA) is a low-grade chronic inflammatory joint disease. Innate immunity contributes to OA progression, mediated by TLR2 and TLR4. We evaluated the role of cluster determinant 44 (CD44), a transmembrane glycoprotein, in regulating TLR2-linked macrophage activation and resultant proinflammatory responses. TLR2 stimulation was performed on differentiated THP-1 macrophages in the presence or absence of a CD44-specific Ab or hyaluronan (HA). NF-kappaB nuclear translocation, IL-1 beta and TNF-alpha gene expression, and protein concentrations were determined. Anti-CD44 Ab and HA treatments reduced NF-kappaB translocation, IL-1beta and TNF-alpha expression, and production (p < 0.001). Inhibition of proinflammatory response in macrophages by HA was mediated by CD44. Protein phosphatase 2A mediated the reduction in NF-kappaB translocation by HA. CD44 knockdown reduced NF-kappaB nuclear translocation and downstream IL-1beta and TNF-alpha protein production following TLR2 receptor stimulation (p < 0.001). CD44+/+ murine bone marrow-derived macrophages produced higher TNF-alpha compared with CD44-/- macrophages following TLR2 stimulation (p < 0.01). HA dose dependently inhibited TLR2-induced TNF-alpha production by murine bone marrow derived macrophages (p < 0.001). OA synovial fluids (SF) stimulated TLR2 and TLR4 receptors and induced NF-kappaB translocation in THP-1 macrophages. Anti-CD44 Ab treatment significantly reduced macrophage activation by OA SF (p < 0.01). CD44 regulated TLR2 responses in human macrophages, whereby a reduction in CD44 levels or engagement of CD44 by its ligand (HA) or a CD44-specific Ab reduced NF-kappaB translocation and downstream proinflammatory cytokine production. A CD44-specific Ab reduced macrophage activation by OA SF, and CD44 is a potentially novel target in OA treatment. PMID- 29196461 TI - miRNA suppression of a Notch repressor directs non-neuronal fate in Drosophila mechanosensory organs. AB - Although there is abundant evidence that individual microRNA (miRNA) loci repress large cohorts of targets, large-scale knockout studies suggest that most miRNAs are phenotypically dispensable. Here, we identify a rare case of developmental cell specification that is highly dependent on miRNA control of an individual target. We observe that binary cell fate choice in the Drosophila melanogaster peripheral sensory organ lineage is controlled by the non-neuronally expressed mir-279/996 cluster, with a majority of notum sensory organs exhibiting transformation of sheath cells into ectopic neurons. The mir-279/996 defect phenocopies Notch loss of function during the sheath-neuron cell fate decision, suggesting the miRNAs facilitate Notch signaling. Consistent with this, mir 279/996 knockouts are strongly enhanced by Notch heterozygosity, and activated nuclear Notch is impaired in the miRNA mutant. Although Hairless (H) is the canonical nuclear Notch pathway inhibitor, and H heterozygotes exhibit bristle cell fate phenotypes reflecting gain-of-Notch signaling, H/+ does not rescue mir 279/996 mutants. Instead, we identify Insensible (Insb), another neural nuclear Notch pathway inhibitor, as a critical direct miR-279/996 target. Insb is posttranscriptionally restricted to neurons by these miRNAs, and its heterozygosity strongly suppresses ectopic peripheral nervous system neurons in mir-279/996 mutants. Thus, proper assembly of multicellular mechanosensory organs requires a double-negative circuit involving miRNA-mediated suppression of a Notch repressor to assign non-neuronal cell fate. PMID- 29196460 TI - Microglia in Alzheimer's disease. AB - Proliferation and activation of microglia in the brain, concentrated around amyloid plaques, is a prominent feature of Alzheimer's disease (AD). Human genetics data point to a key role for microglia in the pathogenesis of AD. The majority of risk genes for AD are highly expressed (and many are selectively expressed) by microglia in the brain. There is mounting evidence that microglia protect against the incidence of AD, as impaired microglial activities and altered microglial responses to beta-amyloid are associated with increased AD risk. On the other hand, there is also abundant evidence that activated microglia can be harmful to neurons. Microglia can mediate synapse loss by engulfment of synapses, likely via a complement-dependent mechanism; they can also exacerbate tau pathology and secrete inflammatory factors that can injure neurons directly or via activation of neurotoxic astrocytes. Gene expression profiles indicate multiple states of microglial activation in neurodegenerative disease settings, which might explain the disparate roles of microglia in the development and progression of AD pathology. PMID- 29196462 TI - p38 MAPK inhibits autophagy and promotes microglial inflammatory responses by phosphorylating ULK1. AB - Inflammation and autophagy are two critical cellular processes. The relationship between these two processes is complex and includes the suppression of inflammation by autophagy. However, the signaling mechanisms that relieve this autophagy-mediated inhibition of inflammation to permit a beneficial inflammatory response remain unknown. We find that LPS triggers p38alpha mitogen-activated protein kinase (MAPK)-dependent phosphorylation of ULK1 in microglial cells. This phosphorylation inhibited ULK1 kinase activity, preventing it from binding to the downstream effector ATG13, and reduced autophagy in microglia. Consistently, p38alpha MAPK activity is required for LPS-induced morphological changes and the production of IL-1beta by primary microglia in vitro and in the brain, which correlates with the p38alpha MAPK-dependent inhibition of autophagy. Furthermore, inhibition of ULK1 alone was sufficient to promote an inflammatory response in the absence of any overt inflammatory stimulation. Thus, our study reveals a molecular mechanism that enables the initial TLR4-triggered signaling pathway to inhibit autophagy and optimize inflammatory responses, providing new understanding into the mechanistic basis of the neuroinflammatory process. PMID- 29196463 TI - Genomic Landscape of Cell-Free DNA in Patients with Colorectal Cancer. AB - "Liquid biopsy" approaches analyzing cell-free DNA (cfDNA) from the blood of patients with cancer are increasingly utilized in clinical practice. However, it is not yet known whether cfDNA sequencing from large cohorts of patients with cancer can detect genomic alterations at frequencies similar to those observed by direct tumor sequencing, and whether this approach can generate novel insights. Here, we report next-generation sequencing data from cfDNA of 1,397 patients with colorectal cancer. Overall, frequencies of genomic alterations detected in cfDNA were comparable to those observed in three independent tissue-based colorectal cancer sequencing compendia. Our analysis also identified a novel cluster of extracellular domain (ECD) mutations in EGFR, mediating resistance by blocking binding of anti-EGFR antibodies. Patients with EGFR ECD mutations displayed striking tumor heterogeneity, with 91% harboring multiple distinct resistance alterations (range, 1-13; median, 4). These results suggest that cfDNA profiling can effectively define the genomic landscape of cancer and yield important biological insights.Significance: This study provides one of the first examples of how large-scale genomic profiling of cfDNA from patients with colorectal cancer can detect genomic alterations at frequencies comparable to those observed by direct tumor sequencing. Sequencing of cfDNA also generated insights into tumor heterogeneity and therapeutic resistance and identified novel EGFR ectodomain mutations. Cancer Discov; 8(2); 164-73.

PMID- 29196464 TI - Deconstruction of a Metastatic Tumor Microenvironment Reveals a Common Matrix Response in Human Cancers. AB - We have profiled, for the first time, an evolving human metastatic microenvironment by measuring gene expression, matrisome proteomics, cytokine and chemokine levels, cellularity, extracellular matrix organization, and biomechanical properties, all on the same sample. Using biopsies of high-grade serous ovarian cancer metastases that ranged from minimal to extensive disease, we show how nonmalignant cell densities and cytokine networks evolve with disease progression. Multivariate integration of the different components allowed us to define, for the first time, gene and protein profiles that predict extent of disease and tissue stiffness, while also revealing the complexity and dynamic nature of matrisome remodeling during development of metastases. Although we studied a single metastatic site from one human malignancy, a pattern of expression of 22 matrisome genes distinguished patients with a shorter overall survival in ovarian and 12 other primary solid cancers, suggesting that there may be a common matrix response to human cancer.Significance: Conducting multilevel analysis with data integration on biopsies with a range of disease involvement identifies important features of the evolving tumor microenvironment. The data suggest that despite the large spectrum of genomic alterations, some human malignancies may have a common and potentially targetable matrix response that influences the course of disease.

PMID- 29196474 TI - Inflammasome activation and assembly at a glance. AB - Inflammasomes are multimeric protein complexes that typically comprise a sensor, an adaptor and the zymogen procaspase-1. An inflammasome assembles in response to a diverse range of pathogen-associated or danger-associated molecular patterns (PAMPs or DAMPs). The inflammasome platform leads to activation of caspase-1 through proximity-induced self-cleavage, which further induces maturation of interleukins 1beta and 18 (IL-1beta and IL-18) through proteolytic cleavage of pro-IL-1beta and pro-IL-18. Activated caspase-1 also cleaves gasdermin D, which leads to a particular form of cell death called pyroptosis. Mutations in genes that encode inflammasome components are associated with many inflammatory disorders, and studies in the past decade have highlighted the importance of appropriate activation of the inflammasome in homeostasis and disease pathogenesis. Therefore, much attention is being paid to uncover the modulators and regulators of inflammasome assembly and pyroptosis. This Cell Science at a Glance article and accompanying poster outlines the concepts in the activation of inflammasome sensors and assembly of the inflammasome platform. We also discuss recent insights into the mechanisms of regulation of inflammasome activity and the induction of cell death by pyroptosis. PMID- 29196475 TI - FYCO1 regulates accumulation of post-mitotic midbodies by mediating LC3-dependent midbody degradation. AB - The post-mitotic midbody (MB) is a remnant of cytokinesis that can be asymmetrically inherited by one of the daughter cells following cytokinesis. Until recently, the MB was thought to be degraded immediately following cytokinesis. However, recent evidence suggests that the MB is a protein-rich organelle that accumulates in stem cell and cancer cell populations, indicating that it may have post-mitotic functions. Here, we investigate the role of FYCO1, an LC3-binding protein (herein, LC3 refers to MAP1LC3B), and its function in regulating the degradation of post-mitotic MBs. We show that FYCO1 is responsible for formation of LC3-containing membrane around the post-mitotic MB and that FYCO1 knockdown increases MB accumulation. Although MBs accumulate in the stem cell-like population of squamous cell carcinomas, FYCO1 depletion does not affect the clonogenicity of these cells. Instead, MB accumulation leads to an increase in anchorage-independent growth and invadopodia formation in HeLa cells and squamous carcinoma cells. Collectively, our data suggest that FYCO1 regulates MB degradation, and we present the first evidence that cancer invasiveness is a feature that can be modulated by the accumulation of MBs in cancer stem cells.This article has an associated First Person interview with the first author of the paper. PMID- 29196477 TI - Usage of unscheduled hospital care by homeless individuals in Dublin, Ireland: a cross-sectional study. AB - OBJECTIVES: Homeless people lack a secure, stable place to live and experience higher rates of serious illness than the housed population. Studies, mainly from the USA, have reported increased use of unscheduled healthcare by homeless individuals.We sought to compare the use of unscheduled emergency department (ED) and inpatient care between housed and homeless hospital patients in a high-income European setting in Dublin, Ireland. SETTING: A large university teaching hospital serving the south inner city in Dublin, Ireland. Patient data are collected on an electronic patient record within the hospital. PARTICIPANTS: We carried out an observational cross-sectional study using data on all ED visits (n=47 174) and all unscheduled admissions under the general medical take (n=7031) in 2015. PRIMARY AND SECONDARY OUTCOME MEASURES: The address field of the hospital's electronic patient record was used to identify patients living in emergency accommodation or rough sleeping (hereafter referred to as homeless). Data on demographic details, length of stay and diagnoses were extracted. RESULTS: In comparison with housed individuals in the hospital catchment area, homeless individuals had higher rates of ED attendance (0.16 attendances per person/annum vs 3.0 attendances per person/annum, respectively) and inpatient bed days (0.3 vs 4.4 bed days/person/annum). The rate of leaving ED before assessment was higher in homeless individuals (40% of ED attendances vs 15% of ED attendances in housed individuals). The mean age of homeless medical inpatients was 44.19 years (95% CI 42.98 to 45.40), whereas that of housed patients was 61.20 years (95% CI 60.72 to 61.68). Homeless patients were more likely to terminate an inpatient admission against medical advice (15% of admissions vs 2% of admissions in homeless individuals). CONCLUSION: Homeless patients represent a significant proportion of ED attendees and medical inpatients. In contrast to housed patients, the bulk of usage of unscheduled care by homeless people occurs in individuals aged 25-65 years. PMID- 29196476 TI - Changes in older people's care profiles during the last 2 years of life, 1996 1998 and 2011-2013: a retrospective nationwide study in Finland. AB - OBJECTIVES: The time of death is increasingly postponed to a very high age. How this change affects the use of care services at the population level is unknown. This study analyses the care profiles of older people during their last 2 years of life, and investigates how these profiles differ for the study years 1996-1998 and 2011-2013. DESIGN: Retrospective cross-sectional nationwide data drawn from the Care Register for Health Care, the Care Register for Social Care and the Causes of Death Register. The data included the use of hospital and long-term care services during the last 2 years of life for all those who died in 1998 and in 2013 at the age of >=70 years in Finland. METHODS: We constructed four care profiles using two criteria: (1) number of days in round-the-clock care (vs at home) in the last 2 years of life and (2) care transitions during the last 6 months of life (ie, end-of-life care transitions). RESULTS: Between the study periods, the average age at death and the number of diagnoses increased. Most older people (1998: 64.3%, 2013: 59.3%) lived at home until their last months of life (profile 2) after which they moved into hospital or long-term care facilities. This profile became less common and the profiles with a high use of care services became more common (profiles 3 and 4 together in 1998: 25.0%, in 2013: 30.9%). People with dementia, women and the oldest old were over represented in the latter profiles. In both study periods, fewer than one in ten stayed at home for the whole last 6 months (profile 1). CONCLUSIONS: Postponement of death to a very old age may translate into more severe disability in the last months or years of life. Care systems must be prepared for longer periods of long term care services needed at the end of life. PMID- 29196478 TI - Efficacy of hypnotherapy compared to cognitive-behavioural therapy for mild-to moderate depression: study protocol of a randomised-controlled rater-blind trial (WIKI-D). AB - INTRODUCTION: Despite a substantial number of studies providing evidence for the efficacy of psychological treatment for mild-to-moderate depression, maximally only 50% of participants respond to treatment, even when using gold-standard treatments such as cognitive-behavioural therapy (CBT) and interpersonal therapy. New approaches such as the 'third wave' psychotherapies have provided promising results; however, studies concerning the comparison with evidence-based treatments are lacking. This study aims to compare the efficacy of clinical hypnotherapy (HT) with gold-standard psychotherapy (CBT) in the treatment of mild to-moderate major depressive episodes. METHODS AND ANALYSIS: The present study comprises a monocentric, two-armed, randomised-controlled, rater-blind (non inferiority) clinical trial. A total of 160 participants with mild-to-moderate major depression episode will be randomly assigned to either CBT or HT involving 20 sessions of psychotherapy over a period of 24 weeks. We predict that the average improvement in the Montgomery-Asberg Depression Rating Scale score will not be inferior in HT compared with CBT (non-inferiority hypothesis).Further outcome parameters will include the number of participants responding to treatment following the completion of treatment and 1 year after. Additionally, quality of life, treatment expectations and hypnotic susceptibility before and after end of treatment will be assessed. ETHICS AND DISSEMINATION: The study protocol and the documents for the informed consent have been approved by the Ethics Committee of the University Hospital Tuebingen (061/2015B02). The results of this trial will be submitted for publication in peer-reviewed journals, and will be presented at national and international conferences.

A case-control experience at the school of medicine of Turin. AB - OBJECTIVES: The usefulness of university admission tests to medical schools has been discussed in recent years. In the academic year 2014-15 in Italy, several students who failed the admission test appealed to the regional administrative court ('Tribunale Amministrativo Regionale'-TAR) requesting to be included, despite their test results, and all were admitted to their respective courses. The existence of this population of students generated a control group, in order to evaluate the predictive capacity of the admission test. The aim of the present work is to discuss the ability of university admission tests to predict subsequent academic success. SETTING AND PARTICIPANTS: The study involved 683 students who enrolled onto the first year of the degree course in medicine in the academic year 2014-15 at the University of Turin (Molinette and San Luigi Gonzaga colleges). The students were separated into two categories: those who passed the admission test (n1=531) and those who did not pass the admission test but won their appeal in the TAR (n2=152). OUTCOMES: The validity of the admission test was analysed using specificity, sensitivity, positive and negative likelihood ratios (LH+, LH-), receiver operating characteristic (ROC) curves, area under the ROC curve (AUC), and relative (95% CI). RESULTS: The results showed that the admission test appeared to be a good tool for predicting the academic performances in the first year of the course (AUC=0.70, 95% CI 0.64 to 0.76). Moreover, some subject areas seemed to have a greater discriminating capacity than others. In general, students who obtained a high score in scientific questions were more likely to obtain the required standards during the first year (LH+ 1.22, 95% CI 1.14 to 1.25). CONCLUSIONS: Based on a consistent statistical approach, our study seems to confirm the ability of the admission test to predict academic success in the first year at the school of medicine of Turin. PMID- 29196479 TI - Sleep Treatment Outcome Predictors (STOP) Pilot Study: a protocol for a randomised controlled trial examining predictors of change of insomnia symptoms and associated traits following cognitive-behavioural therapy for insomnia in an unselected sample. AB - INTRODUCTION: Cognitive-behavioural therapy for insomnia (CBT-I) leads to insomnia symptom improvements in a substantial proportion of patients. However, not everyone responds well to this treatment, and it is unclear what determines individual differences in response. The broader aim of this work is to examine to what extent response to CBT-I is due to genetic and environmental factors. The purpose of this pilot study is to examine feasibility of a design to test hypotheses focusing on an unselected sample, that is, without selection on insomnia complaints, in order to plan a larger behavioural genetics study where most participants will likely not have an insomnia disorder. METHODS AND ANALYSIS: A two parallel-group randomised controlled trial is being conducted across three London universities. Female students (minimum age 18 years) enrolled on a psychology programme at one of the three sites were invited to participate. The target number of participants to be recruited is 240. Following baseline assessments, participants were randomly allocated to either the treatment group, where they received weekly sessions of digital CBT-I for 6 weeks, or the control group, where they completed an online puzzle each week for 6 weeks. Follow-up assessments have taken place mid-intervention (3 weeks) and end of intervention (6 weeks). A 6-month follow-up assessment will also occur. Primary outcomes will be assessed using descriptive statistics and effect size estimates for intervention effects. Secondary outcomes will be analysed using multivariate generalised estimating equation models. ETHICS AND DISSEMINATION: The study received ethical approval from the Research Ethics and Integrity subcommittee, Goldsmiths, University of London (application reference: EA 1305). DNA sample collection for the BioResource received ethical approval from the NRES Committee South Central-Oxford (reference number: 15/SC/0388). The results of this work shall be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03062891; Results. PMID- 29196481 TI - Cardiovascular mortality and oral antidiabetic drugs: protocol for a systematic review and network meta-analysis. AB - INTRODUCTION: Cardiovascular diseases are the leading cause of morbidity and mortality among individuals with diabetes. Despite the beneficial effects of antidiabetic drugs (ADDs) in terms of lowering haemoglobin A1c, several ADDs have been shown to increase the risk of cardiovascular events. Given the high prevalence of cardiovascular disease among individuals with diabetes, it is important to weigh the benefits of ADDs against their cardiovascular safety. Therefore, the objective of the current study is to conduct a systematic review with network meta-analysis to compare the effects of different oral pharmacological classes of ADDs on cardiovascular safety. METHODS AND ANALYSIS: Randomised clinical trials (RCTs) and observational studies published in English up to 31 January 2017, and which include direct and/or indirect evidence, will be included. Studies will be retrieved by searching four electronic databases and cross-referencing. Dual selection and abstraction of data will occur. The primary outcome will be cardiovascular mortality. Secondary outcomes will include all cause mortality, new event of acute myocardial infarction, stroke (haemorrhagic and ischaemic), hospitalisation for acute coronary syndrome and urgent revascularisation procedures. Risk of bias will be assessed using the Cochrane Risk of Bias assessment instrument for RCTs and the Strengthening the Reporting of Observational Studies in Epidemiology instrument for observational studies. Network meta-analysis will be performed using multivariate random-effects meta regression models. The surface under the cumulative ranking curve will be used to provide a hierarchy of ADDs that increase cardiovascular mortality. DISSEMINATION: The results of this study will be presented at a professional conference and submitted to a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42017051220. PMID- 29196482 TI - Do changing levels of maternal exercise during pregnancy affect neonatal adiposity? Secondary analysis of the babies after SCOPE: evaluating the longitudinal impact using neurological and nutritional endpoints (BASELINE) birth cohort (Cork, Ireland). AB - OBJECTIVE: To investigate whether changing levels of exercise during pregnancy are related to altered neonatal adiposity. DESIGN: Secondary analysis of data from a prospective cohort study. SETTING: Cork, Ireland. PARTICIPANTS: 1200 mother - infant pairs recruited as part of a prospective birth cohort, Babies After SCOPE: Evaluating the Longitudinal Impact Using Neurological and Nutritional Endpoints (BASELINE). MAIN OUTCOME MEASURES: Neonatal adiposity was assessed within several days of birth using air displacement plethysmography (PEAPOD). Per cent body fat (BF%) as a continuous outcome and a pair of dichotomous variables; high or low adiposity, representing BF% >90th or <10th centile, respectively. Multivariable linear and logistic regression models were used to investigate the relationship between exercise and the respective outcomes. RESULTS: Crude analysis revealed no association between a changing level of exercise (since becoming pregnant) at 15 weeks' gestation and any of the outcomes (BF%, low adiposity and high adiposity). At 20 weeks' gestation, analyses revealed that relative to women who do not change their exercise level up to 20 weeks, those women who decreased their exercise level were more likely to give birth to a neonate with adiposity above the 90th centile (OR 1.62, 95% CI 1.07 to 2.46). This association was maintained after adjustment for putative confounders (OR 1.62, 95% CI 1.06 to 2.47). CONCLUSIONS: We observed a possible critical period for the association between changing exercise levels and neonatal adiposity, with no association observed with exercise recall for the first 15 weeks of gestation, but an association with a decreasing level of exercise between 15 and 20 weeks. These results should be interpreted in line with the limitations of the study and further studies utilising objectively measured estimates of exercise are required in order to replicate these findings.

PMID- 29196483 TI - Partners at Care Transitions (PACT) -e xploring older peoples' experiences of transitioning from hospital to home in the UK: protocol for an observation and interview study of older people and their families to understand patient experience and involvement in care at transitions. AB - INTRODUCTION: Length of hospital inpatient stays have reduced. This benefits patients, who prefer to be at home, and hospitals, which can treat more people when stays are shorter. Patients may, however, leave hospital sicker, with ongoing care needs. The transition period from hospital to home can be risky, particularly for older patients with complex health and social needs. Improving patient experience, especially through greater patient involvement, may improve outcomes for patients and is a key indicator of care quality and safety. In this research, we aim to: capture the experiences of older patients and their families during the transition from hospital to home, and identify opportunities for greater patient involvement in care, particularly where this contributes to greater individual-level and organisational-level resilience. METHODS AND ANALYSIS: A 'focused ethnography' comprising observations, 'Go-Along' and semistructured interviews will be used to capture patient and carer experiences during different points in the care transition from admission to 90 days after discharge. We will recruit 30 patients and their carers from six hospital departments across two National Health Service (NHS) Trusts. Analysis of observations and interviews will use a framework approach to identify themes to understand the experience of transitions and generate ideas about how patients could be more actively involved in their care. This will include exploring what 'good' care at transitions looks like and seeking out examples of success, as well as recommendations for improvement. ETHICS AND DISSEMINATION: Ethical approval was received from the NHS Research Ethics Committee in Wales. The research findings will add to a growing body of knowledge about patient experience of transitions, in particular providing insight into the experiences of patients and carers throughout the transitions process, in 'real time'. Importantly, the data will be used to inform the development of a patient-centred intervention to improve the quality and safety of transitions. PMID- 29196484 TI - Effect of herbal extract granules combined with otilonium bromide on irritable bowel syndrome with diarrhoea: a study protocol for a randomised controlled trial. AB - INTRODUCTION: Irritable bowel syndrome (IBS), known as a functional and organic gastrointestinal disorder, is a collection of symptoms that occur together and generally include pain or discomfort in the abdomen and changes in bowel movement patterns. Due to the limitations of conventional treatments, alternative IBS treatments are used by many patients worldwide. Samryungbaekchulsan (SRS), a herbal formula, has long been used for alleviating diarrhoea-predominant IBS (D IBS) in traditional Korean medicine. Otilonium bromide (OB) is an antimuscarinic compound used to relieve spasmodic pain in the gut, especially in IBS. Although herbal formulae and Western drugs are commonly coadministered for various diseases in Korea, few clinical studies have been conducted regarding the synergic effects of these treatments for any disease, including D-IBS. METHODS AND ANALYSIS: This trial is a randomised, double-blinded, placebo-controlled, double-dummy, four-arm, parallel study. After a 2-week preparation period, 80 patients with D-IBS will be randomly assigned to one of four treatment groups consisting of SRS (water extract granules, 5 g/pack, three times a day) with OB (tablet form, one capsule three times a day) or their placebos, with treatment lasting for 8 weeks. Post-treatment follow-up will be conducted 4 weeks after the end of treatment. The primary outcome is the finding obtained using the Subject's Global Assessment of Relief method. The secondary outcomes are the severity of symptoms related to D-IBS, determined using a 10-point scale, and the change in symptoms. ETHICS AND DISSEMINATION: This trial has full ethical approval of the Ethics Committee of Catholic Kwandong University International St. Mary's Hospital (IS15MISV0033) and the Korean Ministry of Food and Drug Safety (30769). The results of the study will be disseminated through a peer-reviewed journal and/or conference presentations. TRIAL PROTOCOL VERSION: IS15MISV0033 version 4.0 (25 July 2016).

PMID- 29196485 TI - Cluster-randomised controlled trial to assess the effectiveness and cost effectiveness of an obesity prevention programme for Chinese primary school-aged children: the CHIRPY DRAGON study protocol. AB - INTRODUCTION: Childhood obesity in China has increased more rapidly and over a shorter time period than in other countries. However, there is a paucity of rigorously developed and evaluated prevention interventions. We aim to evaluate the clinical and cost-effectiveness as well as the implementation process of a complex multicomponent intervention developed using the UK Medical Research Council (MRC) framework. This study provides one of the first examples of rigorous development and evaluation of a childhood obesity prevention programme in a non-western population using the MRC methods. METHODS AND ANALYSIS: A cluster-randomised controlled trial in 40 primary schools in Guangzhou, China, including children aged 6-7 years at baseline. Schools will be randomly allocated to either the usual practice (n=20) or intervention arm (n=20). The 12-month intervention consists of four components targeting diet and physical activity behaviours in and outside school, with family involvement. The primary objective is to compare the difference in mean body mass index (BMI) z-score between the intervention and control arms at the end of the intervention (starting March/April 2017). A sample size of 1640 pupils recruited from 40 schools is sufficient to detect a difference of 0.17 units in the mean BMI z-score with a power of 80% (ICC=0.01. ICC, intraclass correlation coefficient) and a significance level of 5%. Treatment effects will be tested using a mixed linear model in STATA adjusting for the child baseline BMI z-score and clustering by school. All analyses will be by intention to treat. Secondary analyses will additionally adjust for prespecified school-level and child-level covariates. The incremental cost-effectiveness ratio for the intervention versus usual practice will be 'cost per quality-adjusted life year (QALY)'. Cost per change in BMI z score will also be assessed. A range of methods will be used to evaluate intervention implementation, mechanisms of impact and contextual factors. ETHICS AND DISSEMINATION: Ethical approval was obtained from the Life and Health Sciences Ethical Review Committee at the University of Birmingham and the Ethical Committee of Guangzhou Centre for Disease Control and Prevention. The primary, secondary, process evaluation and economic evaluation results of the trial will be disseminated through relevant international peer-reviewed journals and conferences.

AB - OBJECTIVES: To explore trainee doctors' experiences of the transition to trained doctor, we answer three questions: (1) What multiple and multidimensional transitions (MMTs) are experienced as participants move from trainee to trained doctor? (2) What facilitates and hinders doctors' successful transition experiences? (3) What is the impact of MMTs on trained doctors? DESIGN: A qualitative longitudinal study underpinned by MMT theory. SETTING: Four training areas (health boards) in the UK. PARTICIPANTS: 20 doctors, 19 higher-stage trainees within 6 months of completing their postgraduate training and 1 staff grade, associate specialist or specialty doctor, were recruited to the 9-month longitudinal audio-diary (LAD) study. All completed an entrance interview, 18 completed LADs and 18 completed exit interviews. METHODS: Data were analysed cross-sectionally and longitudinally using thematic Framework Analysis. RESULTS: Participants experienced a multiplicity of expected and unexpected, positive and negative work-related transitions (eg, new roles) and home-related transitions (eg, moving home) during their trainee-trained doctor transition. Factors facilitating or inhibiting successful transitions were identified at various levels: individual (eg, living arrangements), interpersonal (eg, presence of supportive relationships), systemic (eg, mentoring opportunities) and macro (eg, the curriculum provided by Medical Royal Colleges). Various impacts of transitions were also identified at each of these four levels: individual (eg, stress), interpersonal (eg, trainees' children spending more time in childcare), systemic (eg, spending less time with patients) and macro (eg, delayed start in trainees' new roles). CONCLUSIONS: Priority should be given to developing supportive relationships (both formal and informal) to help trainees transition into their trained doctor roles, as well as providing more opportunities for learning. Further longitudinal qualitative research is now needed with a longer study duration to explore transition journeys for several years into the trained doctor role. PMID- 29196487 TI - Application of time series analysis in modelling and forecasting emergency department visits in a medical centre in Southern Taiwan. AB - OBJECTIVE: Emergency department (ED) overcrowding is acknowledged as an increasingly important issue worldwide. Hospital managers are increasingly paying attention to ED crowding in order to provide higher quality medical services to patients. One of the crucial elements for a good management strategy is demand forecasting. Our study sought to construct an adequate model and to forecast monthly ED visits. METHODS: We retrospectively gathered monthly ED visits from January 2009 to December 2016 to carry out a time series autoregressive integrated moving average (ARIMA) analysis. Initial development of the model was based on past ED visits from 2009 to 2016. A best-fit model was further employed to forecast the monthly data of ED visits for the next year (2016). Finally, we evaluated the predicted accuracy of the identified model with the mean absolute percentage error (MAPE). The software packages SAS/ETS V.9.4 and Office Excel 2016 were used for all statistical analyses. RESULTS: A series of statistical tests showed that six models, including ARIMA (0, 0, 1), ARIMA (1, 0, 0), ARIMA (1, 0, 1), ARIMA (2, 0, 1), ARIMA (3, 0, 1) and ARIMA (5, 0, 1), were candidate models. The model that gave the minimum Akaike information criterion and Schwartz Bayesian criterion and followed the assumptions of residual independence was selected as the adequate model. Finally, a suitable ARIMA (0, 0, 1) structure, yielding a MAPE of 8.91%, was identified and obtained as Visitt=7111.161+(at+0.37462 at-1). CONCLUSION: The ARIMA (0, 0, 1) model can be considered adequate for predicting future ED visits, and its forecast results can be used to aid decision-making processes. PMID- 29196488 TI - Antimicrobial prescribing behaviour in dogs and cats by Belgian veterinarians. AB - The objective of this study is to survey general prescribing behaviour by Belgian companion animal veterinarians and to assess agreement of these practices with current treatment guidelines. Therefore an online survey was administered with five realistic and frequently occurring first-line cases to primary-care veterinary practitioners. For each case a predefined pattern of questions were asked about whether or not they would prescribe antimicrobials, if they would prescribe a non-antimicrobial treatment and if they would perform additional diagnostic steps. The responses were compared with recommendations in national guidelines and recent literature. The overall most prescribed antimicrobials were potentiated amoxicillin (43.0 per cent), fluoroquinolones (14.7 per cent), third generation and fourth-generation cephalosporins (10.9 per cent) and tetracyclines (10.9 per cent). Only 48.3 per cent of the veterinarians complied with the guidelines in nearly all of the clinical scenarios (ie, prescribing antimicrobials when indicated, not prescribing antimicrobials when it is not indicated). Moreover, when prescribing highest priority critically important antimicrobials, susceptibility testing on bacterial cultures was performed in only 12.4 per cent of the prescriptions. The results showed that the prescribing behaviour of antimicrobial compounds by primary-care veterinary practitioners in dogs and cats is often not in agreement with national guidelines. Focus in improvement of this prescribing behaviour should be on performing the appropriate diagnostic steps and decreasing the use of highest priority critically important antimicrobials.

PMID- 29196492 TI - High-fat diet exposure from pre-pubertal age induces polycystic ovary syndrome (PCOS) in rats. AB - Polycystic ovary syndrome (PCOS) is associated with hyperandrogenism, oligo anovulation, polycystic ovaries and metabolic syndrome. Many researchers reported that PCOS often starts with menarche in adolescents. Presently available animal model focuses on ovarian but not metabolic features of PCOS. Therefore, we hypothesized that high-fat diet feeding to pre-pubertal female rats results in both reproductive and metabolic features of PCOS. Pre-pubertal female rats were divided into two groups: group I received normal pellet diet and group II received high-fat diet (HFD). In the letrozole study, adult female rats were divided into two groups: group I received 1% carboxy methyl cellulose and group II received 1 mg/kg letrozole orally. Oral glucose tolerance test, lipid profile, fasting glucose, insulin, estrus cycle, hormonal profile, ovary weight, luteinizing hormone (LH) receptor and follicle-stimulating hormone receptor expression were measured. Polycystic ovarian morphology was assessed through histopathological changes of ovary. Feeding of HFD gradually increase glucose intolerance and fasting insulin levels. Triglyceride level was higher in HFD study while total cholesterol level was higher in the letrozole study. Alteration in testosterone and estrogen levels was observed in both studies. LH receptor expression was upregulated only in HFD study. Histopathological changes like increase cystic follicle, diminished granulosa cell layer and thickened theca cell layer were observed in letrozole as well as HFD study. High-fat diet initiated at pre-puberty age in rats produces both metabolic disturbances and ovarian changes similar to that observed clinically in PCOS patients. Letrozole on the other hand induces change in ovarian structure and function. PMID- 29196491 TI - Diversity of Nicotinic Acetylcholine Receptor Positive Allosteric Modulators Revealed by Mutagenesis and a Revised Structural Model. AB - By combining electrophysiological and computational approaches we have examined a series of positive allosteric modulators (PAMs) acting on the human alpha7 nicotinic acetylcholine receptor (nAChR). Electrophysiological studies have focused on three alpha7-selective PAMs (A-867744, TBS-516, and TQS) that display similar effects on wild-type alpha7 nAChRs. In addition to potentiating agonist evoked responses, all three compounds reduce receptor desensitization and, consequently, are classed as type II PAMs. Despite having similar effects on wild type receptors, A-867744 was found to have profoundly differing effects on mutated receptors compared with TBS-516 and TQS, a finding that is consistent with previous studies indicating that A-867744 may have a different mechanism of action compare with other alpha7-selective type II PAMs. Due to evidence that these PAMs bind within the alpha7 nAChR transmembrane region, we generated and validated new structural models of alpha7. Importantly, we have corrected a previously identified error in the transmembrane region of the original cryo electron microscopy Torpedo model; the only pentameric ligand-gated ion channel imaged in a native lipid membrane. Real-space refinement was used to generate closed and open conformations on which the alpha7 models were based. Consensus docking with an extended series of PAMs with chemical similarity to A-867744, TBS 516, and TQS suggests that all bind to a broadly similar intersubunit transmembrane site. However, differences in the predicted binding of A-867744, compared with TBS-516 and TQS, may help to explain the distinct functional effects of A-867744. Thus, our revised structural models may provide a useful tool for interpreting functional effects of PAMs. PMID- 29196493 TI - Intracytoplasmic sperm injection in domestic and wild mammals. AB - Intracytoplasmic sperm injection (ICSI) has become a useful technique for clinical applications in the horse-breeding industry. However, both ICSI blastocyst and offspring production continues to be limited for most farm and wild species. This article reviews technical differences of ICSI performance among species, possible biological and methodological reasons for the variable efficiency and potential strategies to improve the outcomes. One of the major applications of ICSI in animal production is the reproduction of high-value specimens. Unfortunately, some domestic species like the bovine show low rates of pronuclei formation after sperm injection, which led to the development of various artificial activation protocols and sperm pre-treatments that are discussed in this article. The impact of ICSI technique on equine breeding programs is considered in detail, since in contrast to other species, its use for elite horse reproduction has increased in recent years. ICSI has also been used to produce genetically modified animals; however, despite numerous attempts in several domestic species, only transgenic pigs have been consistently produced. Finally, the ICSI is a promising tool for genetic rescue of endangered and wild species. In conclusion, while ICSI has become a consistent ART for some species, it needs further development for others. The low results obtained for some domestic species, the high training needed and the equipment required have limited this technique to the production of elite specimens or for research purposes. PMID- 29196495 TI - Comparative Transcriptome Profiling Reveals Coding and Noncoding RNA Differences in NSCLC from African Americans and European Americans. AB - Purpose: To determine whether racial differences in gene and miRNA expression translates to differences in lung tumor biology with clinical relevance in African Americans (AAs) and European Americans (EAs).Experimental Design: The NCI Maryland Case Control Study includes seven Baltimore City hospitals and is overrepresented with AA patients (~40%). Patients that underwent curative NSCLC surgery between 1998 and 2014 were enrolled. Comparative molecular profiling used mRNA (n = 22 AAs and 19 EAs) and miRNA (n = 42 AAs and 55 EAs) expression arrays to track differences in paired fresh frozen normal tissues and lung tumor specimens from AAs and EAs. Pathway enrichment, predicted drug response, tumor microenvironment infiltration, cancer immunotherapy antigen profiling, and miRNA target enrichment were assessed.Results: AA-enriched differential gene expression was characterized by stem cell and invasion pathways. Differential gene expression in lung tumors from EAs was primarily characterized by cell proliferation pathways. Population-specific gene expression was partly driven by population-specific miRNA expression profiles. Drug susceptibility predictions revealed a strong inverse correlation between AA resistance and EA sensitivity to the same panel of drugs. Statistically significant differences in M1 and M2 macrophage infiltration were observed in AAs (P < 0.05); however, PD-L1, PD-L2 expression was similar between both.Conclusions: Comparative transcriptomic profiling revealed clear differences in lung tumor biology between AAs and EAs. Increased participation by AAs in lung cancer clinical trials are needed to integrate, and leverage, transcriptomic differences with other clinical information to maximize therapeutic benefit in both AAs and EAs.

AB - The successful interaction between pathogen/parasite and host requires a delicate balance between fitness of the former and survival of the latter. To optimize fitness a parasite/pathogen must effectively create an environment conducive to reproductive success, while simultaneously avoiding or minimizing detrimental host defense response. The association between Microbotryum lychnidis-dioicae and its host Silene latifolia serves as an excellent model to examine such interactions. This fungus is part of a species complex that infects species of the Caryophyllaceae, replacing pollen with the fungal spores. In the current study, transcriptome analyses of the fungus and its host were conducted during discrete stages of bud development so as to identify changes in fungal gene expression that lead to spore development and to identify changes associated with infection in the host plant. In contrast to early biotrophic phase stages of infection for the fungus, the latter stages involve tissue necrosis and in the case of infected female flowers, further changes in the developmental program in which the ovary aborts and a pseudoanther is produced. Transcriptome analysis via Illumina RNA sequencing revealed enrichment of fungal genes encoding small secreted proteins, with hallmarks of effectors and genes found to be relatively unique to the Microbotryum species complex. Host gene expression analyses also identified interesting sets of genes up-regulated, including those involving stress response, host defense response, and several agamous-like MADS-box genes (AGL61 and AGL80), predicted to interact and be involved in male gametophyte development. PMID- 29196497 TI - Powerful Inference with the D-Statistic on Low-Coverage Whole-Genome Data. AB - The detection of ancient gene flow between human populations is an important issue in population genetics. A common tool for detecting ancient admixture events is the D-statistic. The D-statistic is based on the hypothesis of a genetic relationship that involves four populations, whose correctness is assessed by evaluating specific coincidences of alleles between the groups. When working with high-throughput sequencing data, calling genotypes accurately is not always possible; therefore, the D-statistic currently samples a single base from the reads of one individual per population. This implies ignoring much of the information in the data, an issue especially striking in the case of ancient genomes. We provide a significant improvement to overcome the problems of the D statistic by considering all reads from multiple individuals in each population. We also apply type-specific error correction to combat the problems of sequencing errors, and show a way to correct for introgression from an external population that is not part of the supposed genetic relationship, and how this leads to an estimate of the admixture rate. We prove that the D-statistic is approximated by a standard normal distribution. Furthermore, we show that our method outperforms the traditional D-statistic in detecting admixtures. The power gain is most pronounced for low and medium sequencing depth (1-10*), and performances are as good as with perfectly called genotypes at a sequencing depth of 2*. We show the reliability of error correction in scenarios with simulated errors and ancient data, and correct for introgression in known scenarios to estimate the admixture rates.

To identify alternative and less demanding nutritional interventions that extend lifespan, we subjected fruit flies ( Drosophila melanogaster) to weekly nutritional regimens that involved alternating a conventional diet with dietary restriction. Short periods of dietary restriction (up to 2 d) followed by longer periods of a conventional diet yielded minimal increases in lifespan. We found that 3 or more days of contiguous dietary restriction (DR) was necessary to yield a lifespan extension similar to that observed with persistent DR. Female flies were more responsive to these interventions than males. Physiologic changes known to be associated with prolonged DR, such as reduced metabolic rates, showed the same time course as lifespan extension. Moreover, concurrent transcriptional changes indicative of reduced insulin signaling were identified with DR. These physiologic and transcriptional changes were sustained, as they were detectable several days after switching to conventional diets. Taken together, diets with longer periods of DR extended lifespan concurrently with physiologic and transcriptional changes that may underlie this increase in lifespan.-Romey-Glusing, R., Li, Y., Hoffmann, J., von Frieling, J., Knop, M., Pfefferkorn, R., Bruchhaus, I., Fink, C., Roeder, T.

AB - The AT-rich interaction domain (ARID) family of proteins regulates gene expression, development, and differentiation. Although Arid5b has important functions in adipogenesis and chondrogenesis, the role of Arid5b in skeletal muscle myogenesis has not been investigated. Therefore, we isolated primary skeletal muscle cells from Arid5b+/+ and Arid5b-/- mice and characterized differentiation in these cells. We found that Arid5b-/- primary skeletal muscle cells showed differentiation defects and impaired sarcomeric assembly. Microarray analysis revealed down-regulation of the prostanoid biosynthesis pathway in Arid5b-/- myoblasts, including the genes encoding cyclooxygenase (COX)-1 ( Ptgs1) and prostaglandin (PG)I synthase ( Ptgis). Down-regulation of COX-1 and PGI synthase was confirmed by real-time PCR and Western blot analyses. Correspondingly, the production of PGI2, as measured by ELISA, was reduced in Arid5b-/- cells relative to Arid5b+/+ cells. Boyden chamber assays showed that migration was increased but chemotaxis was impaired in Arid5b-/- cells. Myoblast fusion was also inhibited in Arid5b-/- cells compared with Arid5b+/+ cells. Treatment with the PGI2 analog iloprost rescued the defects in myotube formation, migration, and fusion. These results demonstrate that Arid5b has a novel and essential role in skeletal muscle differentiation by regulating PGI2 production. Murray, J., Whitson, R. H., Itakura, K.

AB - Research has identified reduced circulating 25-hydroxyvitamin D [25(OH)D] in individuals with the rs7041 (c.1296T>G) T allele in the vitamin D binding protein gene ( GC); however, the effects of the T allele on vitamin D biomarkers during pregnancy and lactation are unknown. Thus, we examined the metabolic effects of GC rs7041 on vitamin D biomarkers among third-trimester pregnant ( n = 26), lactating ( n = 28), and nonpregnant/nonlactating ( n = 21) women consuming a single amount of vitamin D (511 IU/d) and related nutrients for 10-12 wk. T allele carriers had less circulating 25(OH)D, regardless of reproductive state [thymine-thymine (TT): 80% of guanine-guanine (GG), P = 0.05; guanine-thymine (GT): 85% of GG, P = 0.1]. Among pregnant women, the T allele attenuated the expected increase in vitamin D binding protein (DBP). Specifically, although GG pregnant women exhibited greater DBP (216%, P < 0.0001) than did GG nonpregnant women, that difference was lessened among GT women, and TT pregnant women did not exhibit greater DBP than TT nonpregnant women. Furthermore, TT pregnant women had greater placental 25(OH)D3 to 24,25-dihydroxyvitamin D ratios (251% of GG, P = 0.07) and less osteocalcin, a bone formation marker, in the cord blood of their neonates (24% of GT, P = 0.02). Overall, the GC rs7041 genotype modified the effects of pregnancy on maternal and placental vitamin D metabolism, with possible functional consequences for fetal bone development and infant health.

AB - Poor families without health insurance present unique challenges for pediatricians who want to do what is best for the children who are their patients. Families are often willing to make tremendous sacrifices to pay for recommended and needed medical care. Physicians may have to decide whether, or how strongly to, recommend expensive treatments, especially when any good outcomes associated with such treatments are not guaranteed. How should we balance the considerations of justice and of the child's best interest with the grim realities facing poor families? In this article, we present a case from a tertiary care hospital in India in which doctors and parents struggled to figure out the best options for a young man with end stage renal disease. PMID- 29196503 TI - Sphingolipid regulation of lung epithelial cell mitophagy and necroptosis during cigarette smoke exposure. AB - The mechanisms by which lung structural cells survive toxic exposures to cigarette smoke (CS) are not well defined but may involve proper disposal of damaged mitochondria by macro-autophagy (mitophagy), processes that may be influenced by pro-apoptotic ceramide (Cer) or its precursor dihydroceramide (DHC). Human lung epithelial and endothelial cells exposed to CS exhibited mitochondrial damage, signaled by phosphatase and tensin homolog-induced putative kinase 1 (PINK1) phosphorylation, autophagy, and necroptosis. Although cells responded to CS by rapid inhibition of DHC desaturase, which elevated DHC levels, palmitoyl (C16)-Cer also increased in CS-exposed cells. Whereas DHC augmentation triggered autophagy without cell death, the exogenous administration of C16-Cer was sufficient to trigger necroptosis. Inhibition of Cer-generating acid sphingomyelinase reduced both CS-induced PINK1 phosphorylation and necroptosis. When exposed to CS, Pink1-deficient ( Pink1-/-) mice, which are protected from airspace enlargement compared with wild-type littermates, had blunted C16-Cer elevations and less lung necroptosis. CS-exposed Pink1-/- mice also exhibited significantly increased levels of lignoceroyl (C24)-DHC, along with increased expression of Cer synthase 2 ( CerS2), the enzyme responsible for its production. This suggested that a combination of high C24-DHC and low C16-Cer levels might protect against CS-induced necroptosis. Indeed, CerS2-/- mice, which lack C24-DHC at the expense of increased C16-Cer, were more susceptible to CS, developing airspace enlargement following only 1 month of exposure. These results implicate DHCs, in particular, C24-DHC, as protective against CS toxicity by enhancing autophagy, whereas C16-Cer accumulation contributes to mitochondrial damage and PINK1-mediated necroptosis, which may be amplified by the inhibition of C24-DHC producing CerS2.-Mizumura, K., Justice, M.

AB - The investigation of orphan GPCRs (GPRs) has the potential to uncover novel insights into whole animal physiology. In this study, our goal was to determine the renal localization of Gprc5c, a receptor that we previously reported to be highly expressed in murine whole kidney, and to examine physiologic parameters in Gprc5c knockout (KO) mice to gain insight into function. Gprc5c localized to the apical membrane of renal proximal tubules (PTs) in mice, rats, and humans. With the comparison of Gprc5c wild-type (WT) and KO mice, we found that Gprc5c KO mice have altered acid-base homeostasis. Specifically, Gprc5c KO mice have lower blood pH and higher urine pH compared with WT mice, with a reduced level of titratable acids in their urine. In an in vitro GPCR internalization assay, we observed that Gprc5c internalization (an index of activation) was triggered by alkaline extracellular pH. Furthermore, with the use of an in vitro BCECF assay, we observed that Gprc5c increases Na+/H+ exchanger 3 (NHE3) activity at alkaline pH. We also find that the NHE3 activity is reduced in Gprc5c KO mice by 2 photon imaging in seminaphthorhodafluors (SNARF)-4F-loaded kidney sections. NHE3 is a primary contributor to apical transport of H+ in the renal PT. Together, these data imply that Gprc5c modulates the renal contribution to systemic pH homeostasis, at least in part, by taking part in the regulation of NHE3.

PMID- 29196505 TI - Trends in Executive Functioning in Extremely Preterm Children Across 3 Birth Eras. AB - BACKGROUND AND OBJECTIVES: To determine if executive functioning outcomes at school age are different for extremely preterm (EP; <28 weeks' gestation) or extremely low birth weight (ELBW; <1000 g birth weight) children born in 1991 to 1992, 1997, and 2005 relative to their term-born peers. METHODS: Population-based cohorts of all EP/ELBW survivors born in the state of Victoria, Australia, in 1991 to 1992, 1997, and 2005, and contemporaneous controls (matched for expected date of birth, sex, mother's country of birth [English speaking or not], and health insurance status) were recruited at birth. At 7 to 8 years of age, parents of 613 children who were EP/ELBW and 564 children who were controls rated their children's executive functioning on the Behavior Rating Inventory of Executive Function (BRIEF). The proportion of children with elevated BRIEF scores (in the clinically significant range) in each birth group and era was compared by using logistic regression. Sensitivity analyses explored these associations after excluding children with intellectual impairment. RESULTS: Across the eras, EP/ELBW children had higher rates of elevated scores than controls in almost all BRIEF domains. The 2005 EP/ELBW cohort had increased executive dysfunction compared with earlier cohorts, particularly in working memory and planning and organization. This effect persisted after accounting for demographic factors and weakened slightly when those with intellectual impairment were excluded. CONCLUSIONS: These results indicate a concerning trend of increasing executive dysfunction for EP/ELBW children who were born more recently. This may have adverse implications for other functional domains, such as academic achievement and social-emotional well-being. PMID- 29196506 TI - A Pediatrician's Day in Immigration Court.

AB - Necrotizing enterocolitis (NEC) is a frequently encountered condition in the premature neonate, which can have devastating effects. The signs and symptoms of NEC are variable and can be confused with those of sepsis. An abdominal radiograph is often obtained for diagnosis, and findings that indicate NEC include pneumatosis and portal venous gas. The treatment of NEC includes gastrointestinal rest, gastric decompression, broad-spectrum intravenous antibiotics, and systemic support. A finding of pneumoperitoneum signifies intestinal perforation, which requires surgical intervention. Long-term sequelae of NEC include short-gut syndrome, intestinal stricture, and neurodevelopmental delays. The presentation of intestinal stricture can be puzzling. It can appear at presentation as a bowel obstruction or, conversely, as increased stool output or diarrhea. The clinician should have a high level of suspicion for intestinal stricture in a patient with a history of NEC. PMID- 29196511 TI - Compartment Syndrome in the Pediatric Patient.

AB - Metabolic alterations play an important role in cancer and yet, few metabolic cancer driver genes are known. Here we perform a combined genomic and metabolic modeling analysis searching for metabolic drivers of colorectal cancer. Our analysis predicts FUT9, which catalyzes the biosynthesis of Ley glycolipids, as a driver of advanced-stage colon cancer. Experimental testing reveals FUT9's complex dual role; while its knockdown enhances proliferation and migration in monolayers, it suppresses colon cancer cells expansion in tumorspheres and inhibits tumor development in a mouse xenograft models. These results suggest that FUT9's inhibition may attenuate tumor-initiating cells (TICs) that are known to dominate tumorspheres and early tumor growth, but promote bulk tumor cells. In agreement, we find that FUT9 silencing decreases the expression of the colorectal cancer TIC marker CD44 and the level of the OCT4 transcription factor, which is known to support cancer stemness. Beyond its current application, this work presents a novel genomic and metabolic modeling computational approach that can facilitate the systematic discovery of metabolic driver genes in other types of cancer.

AB - Stator elements consisting of MotA4MotB2 complexes are anchored to the cell wall, extend through the cell membrane, and interact with FliG in the cytoplasmic C ring rotor of the flagellum. The cytoplasmic loop of MotA undergoes proton-driven conformational changes that drive flagellar rotation. Functional regulators inhibit motility by either disengaging or jamming the stator-rotor interaction. Here we show that the YcgR homolog MotI (formerly DgrA) of Bacillus subtilis inhibits motility like a molecular clutch that disengages MotA. MotI-inhibited flagella rotated freely by Brownian motion, and suppressor mutations in MotA that were immune to MotI inhibition were located two residues downstream of the critical force generation site. The 3D structure of MotI bound to c-di-GMP was solved, and MotI-fluorescent fusions localized as transient MotA-dependent puncta at the membrane when induced at subinhibitory levels. Finally, subinhibitory levels of MotI expression resulted in incomplete inhibition and proportional decreases in swimming speed. We propose a model in which flagellar stators are disengaged and sequestered from the flagellar rotor when bound by MotI. PMID- 29196523 TI - DNA replication timing alterations identify common markers between distinct progeroid diseases. AB - Progeroid syndromes are rare genetic disorders that phenotypically resemble natural aging. Different causal mutations have been identified, but no molecular alterations have been identified that are in common to these diseases. DNA replication timing (RT) is a robust cell type-specific epigenetic feature highly conserved in the same cell types from different individuals but altered in disease. Here, we characterized DNA RT program alterations in Hutchinson-Gilford progeria syndrome (HGPS) and Rothmund-Thomson syndrome (RTS) patients compared with natural aging and cellular senescence. Our results identified a progeroid specific RT signature that is common to cells from three HGPS and three RTS patients and distinguishes them from healthy individuals across a wide range of ages. Among the RT abnormalities, we identified the tumor protein p63 gene (TP63) as a gene marker for progeroid syndromes. By using the redifferentiation of four patient-derived induced pluripotent stem cells as a model for the onset of progeroid syndromes, we tracked the progression of RT abnormalities during development, revealing altered RT of the TP63 gene as an early event in disease progression of both HGPS and RTS. Moreover, the RT abnormalities in progeroid patients were associated with altered isoform expression of TP63 Our findings demonstrate the value of RT studies to identify biomarkers not detected by other methods, reveal abnormal TP63 RT as an early event in progeroid disease progression, and suggest TP63 gene regulation as a potential therapeutic target. PMID- 29196524 TI - Protein kinase C and calcineurin cooperatively mediate cell survival under compressive mechanical stress. AB - Cells experience compressive stress while growing in limited space or migrating through narrow constrictions. To survive such stress, cells reprogram their intracellular organization to acquire appropriate mechanical properties. However, the mechanosensors and downstream signaling networks mediating these changes remain largely unknown. Here, we have established a microfluidic platform to specifically trigger compressive stress, and to quantitatively monitor single cell responses of budding yeast in situ. We found that yeast senses compressive stress via the cell surface protein Mid2 and the calcium channel proteins Mid1 and Cch1, which then activate the Pkc1/Mpk1 MAP kinase pathway and calcium signaling, respectively. Genetic analysis revealed that these pathways work in parallel to mediate cell survival. Mid2 contains a short intracellular tail and a serine-threonine-rich extracellular domain with spring-like properties, and both domains are required for mechanosignaling. Mid2-dependent spatial activation of the Pkc1/Mpk1 pathway depolarizes the actin cytoskeleton in budding or shmooing cells, thereby antagonizing polarized growth to protect cells under compressive stress conditions. Together, these results identify a conserved signaling network responding to compressive mechanical stress, which, in higher eukaryotes, may ensure cell survival in confined environments.

AB - Membrane phase behavior has been well characterized in model membranes in vitro under thermodynamic equilibrium state. However, the widely observed differences between biological membranes and their in vitro counterparts are placing more emphasis on nonequilibrium factors, including influx and efflux of lipid molecules. The endoplasmic reticulum (ER) is the largest cellular membrane system and also the most metabolically active organelle responsible for lipid synthesis. However, how the nonequilibrium metabolic activity modulates ER membrane phase has not been investigated. Here, we studied the phase behavior of functional ER in the context of lipid metabolism. Utilizing advanced vibrational imaging technique, that is, stimulated Raman scattering microscopy, we discovered that metabolism of palmitate, a prevalent saturated fatty acid (SFA), could drive solid-like domain separation from the presumably uniformly fluidic ER membrane, a previously unknown phenomenon. The potential of various fatty acids to induce solid phase can be predicted by the transition temperatures of their major metabolites. Interplay between saturated and unsaturated fatty acids is also observed. Hence, our study sheds light on cellular membrane biophysics by underscoring the nonequilibrium metabolic status of living cell. PMID- 29196529 TI - No Association of Waist Circumference and Prostate Cancer in the Cancer Prevention Study II Nutrition Cohort. AB - Background: The relationship between excess body weight and prostate cancer risk is unclear. However, some evidence suggests that waist circumference, which provides a measure of central adiposity, may be positively associated with more advanced stages or grades of prostate cancer.Methods: The association between waist circumference and prostate cancer was investigated among 46,094 men enrolled in the Cancer Prevention Study II Nutrition Cohort, of whom 5,711 were diagnosed with this cancer between 1997 and 2013. Using Cox proportional hazards regression, we examined associations of weight circumference with total and high grade prostate cancer incidence and with prostate cancer mortality.Results: In both categorical and continuous analyses, waist circumference was not associated with total or high-grade (Gleason score >= 8) prostate cancer incidence or with prostate cancer mortality regardless of whether body mass index was adjusted for in the statistical model. Waist circumference was inversely associated with low grade (Gleason score < 8) prostate cancer, but the association was not statistically significant after adjustment for body mass index.Conclusions: Our results suggest that central adiposity, as measured by waist circumference, is not significantly associated with prostate cancer incidence or mortality.Impact: Compared with men in other studies with significant results, men in our study were considerably older, suggesting that age may influence the association between waist circumference and prostate cancer.

AB - Our ability to understand and predict the response of ecosystems to a changing environment depends on quantifying vegetation functional diversity. However, representing this diversity at the global scale is challenging. Typically, in Earth system models, characterization of plant diversity has been limited to grouping related species into plant functional types (PFTs), with all trait variation in a PFT collapsed into a single mean value that is applied globally. Using the largest global plant trait database and state of the art Bayesian modeling, we created fine-grained global maps of plant trait distributions that can be applied to Earth system models. Focusing on a set of plant traits closely coupled to photosynthesis and foliar respiration-specific leaf area (SLA) and dry mass-based concentrations of leaf nitrogen ([Formula: see text]) and phosphorus ([Formula: see text]), we characterize how traits vary within and among over 50,000 [Formula: see text]-km cells across the entire vegetated land surface. We do this in several ways-without defining the PFT of each grid cell and using 4 or 14 PFTs; each model's predictions are evaluated against out-of-sample data. This endeavor advances prior trait mapping by generating global maps that preserve variability across scales by using modern Bayesian spatial statistical modeling in combination with a database over three times larger than that in previous analyses. Our maps reveal that the most diverse grid cells possess trait variability close to the range of global PFT means. PMID- 29196531 TI - IAEA and SNMMI Cooperative Agreement.

AB - Nuclear gene transcription is coordinated with transcript release from the chromatin template and messenger RNA (mRNA) export to the cytoplasm. Here we describe the role of nuclear-localized kinase WNK1 (with no lysine [K] 1) in the mammalian mRNA export pathway even though it was previously established as a critical regulator of ion homeostasis in the cytoplasm. Our data reveal that WNK1 phosphorylates the termination factor PCF11 on its RNA polymerase II (Pol II) C terminal domain (CTD)-interacting domain (CID). Furthermore, phosphorylation of the PCF11 CID weakens its interaction with Pol II. We predict that WNK1 and the associated phosphorylation of the PCF11 CID act to promote transcript release from chromatin-associated Pol II. This in turn facilitates mRNA export to the cytoplasm. PMID- 29196536 TI - Novel transcriptional networks regulated by CLOCK in human neurons. AB - The molecular mechanisms underlying human brain evolution are not fully understood; however, previous work suggested that expression of the transcription factor CLOCK in the human cortex might be relevant to human cognition and disease. In this study, we investigated this novel transcriptional role for CLOCK in human neurons by performing chromatin immunoprecipitation sequencing for endogenous CLOCK in adult neocortices and RNA sequencing following CLOCK knockdown in differentiated human neurons in vitro. These data suggested that CLOCK regulates the expression of genes involved in neuronal migration, and a functional assay showed that CLOCK knockdown increased neuronal migratory distance. Furthermore, dysregulation of CLOCK disrupts coexpressed networks of genes implicated in neuropsychiatric disorders, and the expression of these networks is driven by hub genes with human-specific patterns of expression. These data support a role for CLOCK-regulated transcriptional cascades involved in human brain evolution and function. PMID- 29196537 TI - ESCO1/2's roles in chromosome structure and interphase chromatin organization. AB - ESCO1/2 acetyltransferases mediating SMC3 acetylation and sister chromatid cohesion (SCC) are differentially required for genome integrity and development. Here we established chicken DT40 cell lines with mutations in ESCO1/2, SMC3 acetylation, and the cohesin remover WAPL. Both ESCO1 and ESCO2 promoted SCC, while ESCO2 was additionally and specifically required for proliferation and centromere integrity. ESCO1 overexpression fully suppressed the slow proliferation and centromeric separation phenotypes of esco2 cells but only partly suppressed its chromosome arm SCC defects. Concomitant inactivation of ESCO1 and ESCO2 caused lethality owing to compromised mitotic chromosome segregation. Neither wapl nor acetyl-mimicking smc3-QQ mutations rescued esco1 esco2 lethality. Notably, esco1 esco2 wapl conditional mutants showed very severe proliferation defects associated with catastrophic mitoses and also abnormal interphase chromatin organization patterns. The results indicate that cohesion establishment by vertebrate ESCO1/2 is linked to interphase chromatin architecture formation, a newly identified function of cohesin acetyltransferases that is both fundamentally and medically relevant. PMID- 29196538 TI - Parental DNA Methylation States Are Associated with Heterosis in Epigenetic Hybrids. AB - Despite the importance and wide exploitation of heterosis in commercial crop breeding, the molecular mechanisms behind this phenomenon are not completely understood. Recent studies have implicated changes in DNA methylation and small RNAs in hybrid performance; however, it remains unclear whether epigenetic changes are a cause or a consequence of heterosis. Here, we analyze a large panel of over 500 Arabidopsis (Arabidopsis thaliana) epigenetic hybrid plants (epiHybrids), which we derived from near-isogenic but epigenetically divergent parents. This proof-of-principle experimental system allowed us to quantify the contribution of parental methylation differences to heterosis. We measured traits such as leaf area, growth rate, flowering time, main stem branching, rosette branching, and final plant height and observed several strong positive and negative heterotic phenotypes among the epiHybrids. Using an epigenetic quantitative trait locus mapping approach, we were able to identify specific differentially methylated regions in the parental genomes that are associated with hybrid performance. Sequencing of methylomes, transcriptomes, and genomes of selected parent-epiHybrid combinations further showed that these parental differentially methylated regions most likely mediate the remodeling of methylation and transcriptional states at specific loci in the hybrids. Taken together, our data suggest that locus-specific epigenetic divergence between the parental lines can directly or indirectly trigger heterosis in Arabidopsis hybrids independent of genetic changes. These results add to a growing body of evidence that points to epigenetic factors as one of the key determinants of hybrid performance. PMID- 29196541 TI - Validation of the grown-ups with congenital heart disease score. AB - OBJECTIVES: Adults with congenital heart disease in need of heart surgery frequently present with significant comorbidity. Furthermore, additional technical difficulties often related to redo operations increase the risk for postoperative mortality and morbidity. Hence, next to the type of the procedure, additional procedure-dependent and procedure-independent factors have to be considered for risk evaluation. The recently proposed grown-ups with congenital heart disease (GUCH) mortality and morbidity scores account for these additional risk factors. We sought to validate their predictive power in a large population operated in a single centre. METHODS: Data of all consecutive patients aged 18 years or more, who underwent surgery for congenital heart disease between 2005 and 2016, were collected. Mortality was defined as hospital mortality or mortality within 30 days following surgery. Morbidity was defined as occurrence of one or more of the following complications: renal failure requiring dialysis, neurologic deficit persisting at discharge, atrioventricular block requiring permanent pacemaker implantation, mechanical circulatory support, phrenic nerve injury and unplanned reoperation. The discriminatory power of the GUCH scores was assessed using the area under the receiver operating characteristics curve (c index, including 95% CI). RESULTS: Eight hundred and twenty-four operations were evaluated. Additional procedure-dependent and procedure-independent factors, as defined in the GUCH scores, were present in 165 patients (20.0%) and 544 patients (66.0%), respectively. Hospital mortality and morbidity was 3.4% and 10.0%, respectively. C-index for GUCH mortality score was 0.809 (0.742-0.877). C-index for GUCH morbidity score was 0.676 (0.619-0.734). CONCLUSIONS: We could confirm the good predictive power of the GUCH mortality score for postoperative mortality in a large population of adults with congenital heart disease. PMID- 29196539 TI - Biochemical and Structural Analysis of Substrate Specificity of a Phenylalanine Ammonia-Lyase. AB - Phenylalanine ammonia-lyase (PAL) is the first enzyme of the general phenylpropanoid pathway catalyzing the nonoxidative elimination of ammonia from l phenylalanine to give trans-cinnamate. In monocots, PAL also displays tyrosine ammonia lyase (TAL) activity, leading to the formation of p-coumaric acid. The catalytic mechanism and substrate specificity of a major PAL from sorghum (Sorghum bicolor; SbPAL1), a strategic plant for bioenergy production, were deduced from crystal structures, molecular docking, site-directed mutagenesis, and kinetic and thermodynamic analyses. This first crystal structure of a monocotyledonous PAL displayed a unique conformation in its flexible inner loop of the 4-methylidene-imidazole-5-one (MIO) domain compared with that of dicotyledonous plants. The side chain of histidine-123 in the MIO domain dictated the distance between the catalytic MIO prosthetic group created from 189Ala-Ser Gly191 residues and the bound l-phenylalanine and l-tyrosine, conferring the deamination reaction through either the Friedel-Crafts or E2 reaction mechanism. Several recombinant mutant SbPAL1 enzymes were generated via structure-guided mutagenesis, one of which, H123F-SbPAL1, has 6.2 times greater PAL activity without significant TAL activity. Additional PAL isozymes of sorghum were characterized and categorized into three groups. Taken together, this approach identified critical residues and explained substrate preferences among PAL isozymes in sorghum and other monocots, which can serve as the basis for the engineering of plants with enhanced biomass conversion properties, disease resistance, or nutritional quality. PMID- 29196540 TI - Propensity score matched analysis of partial atrioventricular septal defect repair in infancy. AB - OBJECTIVE: Partial atrioventricular septal defect (pAVSD) is usually repaired between 2 and 4 years of age with excellent results. Repair during infancy has been associated with poorer outcomes. However, most infants in reported series had heart failure or significant left atrioventricular valve (LAVV) regurgitation. The impact of surgery during infancy on outcomes remains unclear. METHODS: All children at three institutions who underwent repair of pAVSD from 1975 to 2015 were included. Infants (aged <1 year) were compared with older children in a propensity score matched analysis. Variables used to generate propensity scores were: failure to thrive, congestive heart failure, preoperative LAVV regurgitation, associated congenital heart disease, sex and the presence of trisomy 21. RESULTS: pAVSD repair was performed on 430 children, 17.4% (75/430) were infants. Infants (mean age 0.5+/-0.3 years) had higher rates of LAVV regurgitation, heart failure and additional cardiac malformations than older children (mean age 4.7+/-3.5 years). At 30 years, survival for infants was 82.1% (95% CI 70.1% to 89.6%) compared with 95.7% (95% CI 91.3% to 97.9%) in older children (P<0.001).Propensity score matching yielded 52 well-matched pairs. Survival at 30 years was 87.9% (95% CI 75.0% to 94.4%) for infants compared with 98.1% (95% CI 87.1% to 99.7%) for older children (P=0.04). There was no significant difference in freedom from reoperation between the groups. CONCLUSIONS: Despite matching for risk factors, survival after repair of pAVSD during infancy is lower than that when repair is performed in older children, with no difference in reoperation rates. This suggests that elective repair of pAVSD should be deferred until after infancy. PMID- 29196543 TI - Fluorodeoxyglucose Positron Emission Tomography for Giant Cell Arteritis.

PMID- 29196542 TI - Cardiac myosin-binding protein C is a novel marker of myocardial injury and fibrosis in aortic stenosis. AB - OBJECTIVE: Cardiac myosin-binding protein C (cMyC) is an abundant sarcomeric protein and novel highly specific marker of myocardial injury. Myocyte death characterises the transition from hypertrophy to replacement myocardial fibrosis in advanced aortic stenosis. We hypothesised that serum cMyC concentrations would be associated with cardiac structure and outcomes in patients with aortic stenosis. METHODS: cMyC was measured in two cohorts in which serum had previously been prospectively collected: a mechanism cohort of patients with aortic stenosis (n=161) and healthy controls (n=46) who underwent cardiac MRI, and an outcome cohort with aortic stenosis (n=104) followed for a median of 11.3 years. RESULTS: In the mechanism cohort, cMyC concentration correlated with left ventricular mass (adjusted I2=11.0 g/m2 per log unit increase in cMyC, P<0.001), fibrosis volume (adjusted I2=8.0 g, P<0.001) and extracellular volume (adjusted I2=1.3%, P=0.01) in patients with aortic stenosis but not in controls. In those with late gadolinium enhancement (LGE) indicative of myocardial fibrosis, cMyC concentrations were higher (32 (21-56) ng/L vs 17 (12-24) ng/L without LGE, P<0.001). cMyC was unrelated to coronary calcium scores. Unadjusted Cox proportional hazards analysis in the outcome cohort showed greater all-cause mortality (HR 1.49 per unit increase in log cMyC, 95% CI 1.11 to 2.01, P=0.009). CONCLUSIONS: Serum cMyC concentration is associated with myocardial hypertrophy, fibrosis and an increased risk of mortality in aortic stenosis. The quantification of serum sarcomeric protein concentrations provides objective measures of disease severity and their clinical utility to monitor the progression of aortic stenosis merits further study.

AB - More than a hundred proteins comprise the RAS superfamily of small GTPases. This family can be divided into RAS, RHO, RAB, RAN, ARF, and RAD subfamilies, with each shown to play distinct roles in human cells in both health and disease. The RAS subfamily has a well-established role in human cancer with the three genes, HRAS, KRAS, and NRAS being the commonly mutated in tumors. These RAS mutations, most often functionally activating, are especially common in pancreatic, lung, and colorectal cancers. Efforts to inhibit RAS and related GTPases have produced inhibitors targeting the downstream effectors of RAS signaling, including inhibitors of the RAF-mitogen-activated protein kinase/extracellular signal related kinase (ERK)-ERK kinase pathway and the phosphoinositide-3-kinase-AKT mTOR kinase pathway. A third effector arm of RAS signaling, mediated by RAL (RAS like) has emerged in recent years as a critical driver of RAS oncogenic signaling and has not been targeted until recently. RAL belongs to the RAS branch of the RAS superfamily and shares a high structural similarity with RAS. In human cells, there are two genes, RALA and RALB, both of which have been shown to play roles in the proliferation, survival, and metastasis of a variety of human cancers, including lung, colon, pancreatic, prostate, skin, and bladder cancers. In this review, we summarize the latest knowledge of RAL in the context of human cancer and the recent advancements in the development of cancer therapeutics targeting RAL small GTPases. PMID- 29196559 TI - Remarkable Evolutionary Plasticity of Centromeric Chromatin. AB - Centromeres were familiar to cell biologists in the late 19th century, but for most eukaryotes the basis for centromere specification has remained enigmatic. Much attention has been focused on the cenH3 (CENP-A) histone variant, which forms the foundation of the centromere. To investigate the DNA sequence requirements for centromere specification, we applied a variety of epigenomic approaches, which have revealed surprising diversity in centromeric chromatin properties. Whereas each point centromere of budding yeast is occupied by a single precisely positioned tetrameric nucleosome with one cenH3 molecule, the "regional" centromeres of fission yeast contain unphased presumably octameric nucleosomes with two cenH3s. In Caenorhabditis elegans, kinetochores assemble all along the chromosome at sites of cenH3 nucleosomes that resemble budding yeast point centromeres, whereas holocentric insects lack cenH3 entirely. The "satellite" centromeres of most animals and plants consist of cenH3-containing particles that are precisely positioned over homogeneous tandem repeats, but in humans, different alpha-satellite subfamilies are occupied by CENP-A nucleosomes with very different conformations. We suggest that this extraordinary evolutionary diversity of centromeric chromatin architectures can be understood in terms of the simplicity of the task of equal chromosome segregation that is continually subverted by selfish DNA sequences. PMID- 29196558 TI - Microfluidic isoform sequencing shows widespread splicing coordination in the human transcriptome. AB - Understanding transcriptome complexity is crucial for understanding human biology and disease. Technologies such as Synthetic long-read RNA sequencing (SLR-RNA seq) delivered 5 million isoforms and allowed assessing splicing coordination. Pacific Biosciences and Oxford Nanopore increase throughput also but require high input amounts or amplification. Our new droplet-based method, sparse isoform sequencing (spISO-seq), sequences 100k-200k partitions of 10-200 molecules at a time, enabling analysis of 10-100 million RNA molecules. SpISO-seq requires less than 1 ng of input cDNA, limiting or removing the need for prior amplification with its associated biases. Adjusting the number of reads devoted to each molecule reduces sequencing lanes and cost, with little loss in detection power. The increased number of molecules expands our understanding of isoform complexity. In addition to confirming our previously published cases of splicing coordination (e.g., BIN1), the greater depth reveals many new cases, such as MAPT Coordination of internal exons is found to be extensive among protein coding genes: 23.5%-59.3% (95% confidence interval) of highly expressed genes with distant alternative exons exhibit coordination, showcasing the need for long-read transcriptomics. However, coordination is less frequent for noncoding sequences, suggesting a larger role of splicing coordination in shaping proteins. Groups of genes with coordination are involved in protein-protein interactions with each other, raising the possibility that coordination facilitates complex formation and/or function. We also find new splicing coordination types, involving initial and terminal exons. Our results provide a more comprehensive understanding of the human transcriptome and a general, cost-effective method to analyze it. PMID- 29196557 TI - SelexGLM differentiates androgen and glucocorticoid receptor DNA-binding preference over an extended binding site. AB - The DNA-binding interfaces of the androgen (AR) and glucocorticoid (GR) receptors are virtually identical, yet these transcription factors share only about a third of their genomic binding sites and regulate similarly distinct sets of target genes. To address this paradox, we determined the intrinsic specificities of the AR and GR DNA-binding domains using a refined version of SELEX-seq. We developed an algorithm, SelexGLM, that quantifies binding specificity over a large (31-bp) binding site by iteratively fitting a feature-based generalized linear model to SELEX probe counts. This analysis revealed that the DNA-binding preferences of AR and GR homodimers differ significantly, both within and outside the 15-bp core binding site. The relative preference between the two factors can be tuned over a wide range by changing the DNA sequence, with AR more sensitive to sequence changes than GR. The specificity of AR extends to the regions flanking the core 15-bp site, where isothermal calorimetry measurements reveal that affinity is augmented by enthalpy-driven readout of poly(A) sequences associated with narrowed minor groove width. We conclude that the increased specificity of AR is correlated with more enthalpy-driven binding than GR. The binding models help explain differences in AR and GR genomic binding and provide a biophysical rationale for how promiscuous binding by GR allows functional substitution for AR in some castration-resistant prostate cancers. PMID- 29196560 TI - Spindle-to-Cortex Communication in Cleaving Frog Eggs. AB - During cytokinesis, the mitotic spindle communicates with the cell cortex to position a cleavage furrow that will cut through the cell in the plane defined by the metaphase plate. We investigated the molecular basis of this communication in Xenopus laevis eggs, where the signal has to travel ~400 um in ~30 min to reach the cortex from the first anaphase spindle. At anaphase onset, huge microtubule asters grow out from the poles of the spindle and meet at the plane previously defined by the metaphase plate. This disc-shaped boundary plane recruits the chromosome passenger complex (CPC) and centralspindlin to antiparallel microtubule bundles. It grows out to the cell cortex as the asters expand, where it induces the furrow. CPC and centralspindlin were not recruited to boundaries between asters from different spindles, suggesting a role of chromatin in triggering the CPC-positive state. Recruitment of CPC to aster boundaries was reconstituted in an extract system, and we observed that recruitment was stimulated by proximity to chromatin. Finally, we discuss models for molecular processes involved in initiation and growth of the CPC-positive disc that communicates the position of the metaphase plate to the cortex over hundreds of micrometers in frog eggs. PMID- 29196561 TI - Hierarchical Regulation of Centromeric Cohesion Protection by Meikin and Shugoshin during Meiosis I. AB - The kinetochore is the key apparatus regulating chromosome segregation. Particularly in meiosis, unlike in mitosis, sister kinetochores are captured by microtubules emanating from the same spindle pole (mono-orientation), and sister chromatid cohesion mediated by cohesin is protected at centromeres in the following anaphase. Shugoshin, which localizes to centromeres depending on the phosphorylation of histone H2A by Bub1 kinase, plays a central role in protecting meiotic cohesin Rec8 from separase cleavage. Another key meiotic kinetochore factor, Moa1 (meikin), which was initially characterized as a mono-orientation factor in fission yeast, also regulates cohesion protection. Moa1, which associates stably with CENP-C during meiosis I, recruits Plo1 (polo-like kinase) to the kinetochores and phosphorylates Spc7 (KNL1), inducing the persistent accumulation of Bub1 at kinetochores. The meiotic Bub1 pool ensures robust Sgo1 (shugoshin) localization and cohesion protection at centromeres by cooperating with heterochromatin protein Swi6, which binds and stabilizes Sgo1. Further, molecular genetic analyses reveal a hierarchical regulation of centromeric cohesion protection by meikin and shugoshin during meiosis I. PMID- 29196562 TI - The Role of Bromodomain and Extraterminal Motif (BET) Proteins in Chromatin Structure. AB - Bromodomain and extraterminal motif (BET) proteins have been widely investigated for their roles in gene regulation and their potential as therapeutic targets in cancer. Pharmacologic BET inhibitors target the conserved bromodomain acetyllysine interaction and do not distinguish between BRD2, BRD3, and BRD4. Thus, comparatively little is known regarding the distinct roles played by individual family members, as well as the underlying mechanisms that drive the transcriptional effects of BET inhibitors. Here we review studies regarding the contributions of BET proteins to genome structure and function, including recent work identifying a role for BRD2 as a component of functional and physical chromatin domain boundaries. We also discuss directions of future studies aimed at providing insights into broader architectural functions of BET proteins and their roles in chromatin domain boundary formation.

Surprisingly, the third stage, which appears to be critical for neural fate commitment, depends almost entirely on intracellular signaling.

PMID- 29196573 TI - Costs of informal nursing care for patients with neurologic disorders: A systematic review. AB - OBJECTIVE: To systematically review the economic burden of informal nursing care (INC), often called informal care, caused by multiple sclerosis (MS), Parkinson disease (PD), and epilepsy, with special attention to disease severity. METHODS: We systematically searched MEDLINE, PsycINFO, and NHS Economic Evaluation Database for articles on the cost of illness of the diseases specified. Title, abstract, and full-text review were conducted in duplicate by 2 researchers. The distribution of hours and costs of INC were extracted and used to compare the relevance of INC across included diseases and disease severity. RESULTS: Seventy one studies were included (44 on MS, 17 on PD, and 10 on epilepsy). Studies on epilepsy reported an average of 2.3-54.5 monthly hours of INC per patient. For PD, average values of 42.9-145.9 hours and for MS average values of 9.2-249 hours per patient per month were found. In line with utilized hours, costs of INC were lowest for epilepsy (interquartile range [IQR] 229-1,466 purchasing power parity US dollars [PPP-USD]) and similar for MS (IQR 4,454-11,222 PPP-USD) and PD (IQR 1,440-7,117 PPP-USD). In addition, costs of INC increased with disease severity and accounted for 38% of total health care costs in severe MS stages on average. CONCLUSIONS: The course of diseases and disease severity matter for the amount of INC used by patients. For each of the neurologic disorders, an increase in the costs of INC, due to increasing disease severity, considerably contributes to the rise in total health care costs. PMID- 29196574 TI - Clinical biomarkers differentiate myelitis from vascular and other causes of myelopathy. AB - OBJECTIVE: To assess the predictive value of the initial clinical and paraclinical features in the differentiation of inflammatory myelopathies from other causes of myelopathy in patients with initial diagnosis of transverse myelitis (TM). METHODS: We analyzed the clinical presentation, spinal cord MRI, and CSF features in a cohort of 457 patients referred to a specialized myelopathy center with the presumptive diagnosis of TM. After evaluation, the myelopathies were classified as inflammatory, ischemic/stroke, arteriovenous malformations/fistulas, spondylotic, or other. A multivariable logistic regression model was used to determine characteristics associated with the final diagnosis and predictors that would improve classification accuracy. RESULTS: Out of 457 patients referred as TM, only 247 (54%) were confirmed as inflammatory; the remaining 46% were diagnosed as vascular (20%), spondylotic (8%), or other myelopathy (18%). Our predictive model identified the temporal profile of symptom presentation (hyperacute <6 hours, acute 6-48 hours, subacute 48 hours-21 days, chronic >21 days), initial motor examination, and MRI lesion distribution as characteristics that improve the correct classification rate of myelopathies from 67% to 87% (multinomial area under the curve increased from 0.32 to 0.67), compared to only considering CSF pleocytosis and MRI gadolinium enhancement. Of all predictors, the temporal profile of symptoms contributed the most to the increased discriminatory power. CONCLUSIONS: The temporal profile of symptoms serves as a clinical biomarker in the differential diagnosis of TM. The establishment of a definite diagnosis in TM requires a critical analysis of the MRI and CSF characteristics to rule out non-inflammatory causes of myelopathy. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that for patients presenting with myelopathy, temporal profile of symptoms, initial motor examination, and MRI lesion distribution distinguish those with inflammatory myelopathies from those with other causes of myelopathy. PMID- 29196575 TI - Pitfalls in developing precision medicine for genetic epilepsy. PMID- 29196576 TI - Apathy is associated with incident dementia in community-dwelling older people. AB - OBJECTIVE: To assess whether apathy and depressive symptoms are independently associated with incident dementia during 6-year follow-up in a prospective observational population-based cohort study. METHODS: Participants were community dwelling older people in the Prevention of Dementia by Intensive Vascular Care trial, aged 70-78 years, without dementia at baseline. Apathy and depressive symptoms were measured using the 15-item Geriatric Depression Scale (GDS-15). Dementia during follow-up was established by clinical diagnosis confirmed by an independent outcome adjudication committee. Hazard ratios (HRs) were calculated using Cox regression analyses. Given its potentially strong relation with incipient dementia, the GDS item referring to memory complaints was assessed separately. RESULTS: Dementia occurred in 232/3,427 (6.8%) participants. Apathy symptoms were associated with dementia (HR 1.28, 95% confidence interval [CI] 1.12-1.45; p < 0.001), also after adjustment for age, sex, Mini-Mental State Examination score, disability, and history of stroke or cardiovascular disease (HR 1.21, 95% CI 1.06-1.40; p = 0.007), and in participants without depressive symptoms (HR 1.26, 95% CI 1.06-1.49; p = 0.01). Depressive symptoms were associated with dementia (HR 1.12, 95% CI 1.05-1.19), also without apathy symptoms (HR 1.16, 95% CI 1.03-1.31; p = 0.015), but not after full adjustment or after removing the GDS item on memory complaints. CONCLUSIONS: Apathy and depressive symptoms are independently associated with incident dementia in community-dwelling older people. Subjective memory complaints may play an important role in the association between depressive symptoms and dementia. Our findings suggest apathy symptoms may be prodromal to dementia and might be used in general practice to identify individuals without cognitive impairment at increased risk of dementia.

PMID- 29196578 TI - Precision therapy for epilepsy due to KCNT1 mutations: A randomized trial of oral quinidine. AB - OBJECTIVE: To evaluate quinidine as a precision therapy for severe epilepsy due to gain of function mutations in the potassium channel gene KCNT1. METHODS: A single-center, inpatient, order-randomized, blinded, placebo-controlled, crossover trial of oral quinidine included 6 patients with severe autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) due to KCNT1 mutation. Order was block randomized and blinded. Four-day treatment blocks were used with a 2 day washout between. Dose started at 900 mg over 3 divided doses then, in subsequent participants, was reduced to 600 mg, then 300 mg. Primary outcome was seizure frequency measured on continuous video-EEG in those completing the trial. RESULTS: Prolonged QT interval occurred in the first 2 patients at doses of 900 and 600 mg quinidine per day, respectively, despite serum quinidine levels well below the therapeutic range (0.61 and 0.51 MUg/mL, reference range 1.3-5.0 MUg/mL). Four patients completed treatment with 300 mg/d without adverse events. Patients completing the trial had very frequent seizures (mean 14 per day, SD 7, median 13, interquartile range 10-18). Seizures per day were nonsignificantly increased by quinidine (median 2, 95% confidence interval -1.5 to +5, p = 0.15) and no patient had a 50% seizure reduction. CONCLUSION: Quinidine did not show efficacy in adults and teenagers with ADNFLE. Dose-limiting cardiac side effects were observed even in the presence of low measured serum quinidine levels. Although small, this trial suggests use of quinidine in ADNFLE is likely to be ineffective coupled with considerable cardiac risks. CLINICAL TRIALS REGISTRATION: Australian Therapeutic Goods Administration Clinical Trial Registry (trial number 2015/0151). CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that for persons with severe epilepsy due to gain of function mutations in the potassium channel gene KCNT1, quinidine does not significantly reduce seizure frequency. PMID- 29196580 TI - Sex disparities in access to caregiving in Parkinson disease. AB - OBJECTIVE: To compare access to caregiving between men and women with Parkinson disease (PD). METHODS: This was a cross-sectional and longitudinal study among participants with PD enrolled in the National Parkinson Foundation Parkinson's Outcomes Project from 2009 to 2014 at 21 international sites. The primary outcome measures were presence of a caregiver at the baseline visit, caregiver burden as measured by the Multidimensional Caregiver Strain Index (MCSI) at baseline, and time to first paid caregiver. RESULTS: A total of 7,209 participants (63% men, 37% women) with PD were evaluated. Men had a mean age of 66.0 (SD 9.8) years, and women had a mean age of 66.9 (SD 9.7) years. More men than women had a caregiver (88.4% vs 79.4%, p < 0.0001). Caregivers of men reported greater strain than those of women (MCSI score 19.9 vs 16.4, p < 0.0001). These differences persisted after controlling for age, disease stage, number of comorbidities, cognitive and mobility measures, and health-related quality of life. In addition, the odds of caregiver accompaniment at baseline visit were lower for women compared to men (odds ratio 0.76, 95% confidence interval [CI] 0.67-0.86), and women had a faster rate to using a paid caregiver than men (hazard ratio 1.76, 95% CI 1.35-2.28) after controlling for potential confounders. CONCLUSIONS: Informal caregiving resources are lower for women than men with PD, despite the finding that their caregivers report less strain than those of men. In addition, women are more likely to use formal, paid caregivers. Strategies to improve access to caregiving, particularly for women, are needed. PMID- 29196579 TI - Clinical and molecular characterization of KCNT1-related severe early-onset epilepsy. AB - OBJECTIVE: To characterize the phenotypic spectrum, molecular genetic findings, and functional consequences of pathogenic variants in early-onset KCNT1 epilepsy. METHODS: We identified a cohort of 31 patients with epilepsy of infancy with migrating focal seizures (EIMFS) and screened for variants in KCNT1 using direct Sanger sequencing, a multiple-gene next-generation sequencing panel, and whole exome sequencing. Additional patients with non-EIMFS early-onset epilepsy in whom we identified KCNT1 variants on local diagnostic multiple gene panel testing were also included. When possible, we performed homology modeling to predict the putative effects of variants on protein structure and function. We undertook electrophysiologic assessment of mutant KCNT1 channels in a xenopus oocyte model system. RESULTS: We identified pathogenic variants in KCNT1 in 12 patients, 4 of which are novel. Most variants occurred de novo. Ten patients had a clinical diagnosis of EIMFS, and the other 2 presented with early-onset severe nocturnal frontal lobe seizures. Three patients had a trial of quinidine with good clinical response in 1 patient. Computational modeling analysis implicates abnormal pore function (F346L) and impaired tetramer formation (F502V) as putative disease mechanisms. All evaluated KCNT1 variants resulted in marked gain of function with significantly increased channel amplitude and variable blockade by quinidine. CONCLUSIONS: Gain-of-function KCNT1 pathogenic variants cause a spectrum of severe focal epilepsies with onset in early infancy. Currently, genotype phenotype correlations are unclear, although clinical outcome is poor for the majority of cases. Further elucidation of disease mechanisms may facilitate the development of targeted treatments, much needed for this pharmacoresistant genetic epilepsy. PMID- 29196581 TI - Increased midlife triglycerides predict brain beta-amyloid and tau pathology 20 years later. AB - OBJECTIVE: To evaluate the effect of midlife lipid levels on Alzheimer brain pathology 20 years later in cognitively normal elderly individuals. METHODS: This is a longitudinal cohort study of 318 cognitively normal individuals with data on fasting lipid levels at midlife (mean age 54 years). Presence of beta-amyloid (Abeta) and tau pathologies 20 years later (mean age 73 years) were detected by quantifying Alzheimer disease (AD) biomarkers in CSF. In a subset (n = 134), Abeta (18F-flutemetamol) PET was also performed. RESULTS: CSF Abeta42 and Abeta PET revealed Abeta pathology in approximately 20% of the cognitively healthy population and CSF Abeta42/phosphorylated tau (p-tau) ratio indicated both Abeta and tau pathology in 16%. Higher levels of triglycerides in midlife were independently associated with abnormal CSF Abeta42 (odds ratio [OR] 1.34, 95% confidence interval [CI] 1.03-1.75, p = 0.029) and abnormal Abeta42/p-tau ratio (OR 1.46, 95% CI 1.10-1.93; p = 0.009) adjusting for age, sex, APOE epsilon4, education, and multiple vascular risk factors. Triglycerides were also associated with abnormal Abeta PET in multivariable regression models, but the association was attenuated in the fully adjusted model. Increased levels of medium and large low-density lipoprotein subfractions were significantly associated with abnormal Abeta PET and large high-density lipoprotein particles were associated with decreased risk of abnormal Abeta PET. CONCLUSIONS: Increased levels of triglycerides at midlife predict brain Abeta and tau pathology 20 years later in cognitively healthy individuals. Certain lipoprotein subfractions may also be risk factors for Abeta pathology. These findings further support an involvement of lipids in the very early stages of AD development. PMID- 29196583 TI - A Season of Thanks and Hope. PMID- 29196585 TI - Feasibility of a Nurse-Managed Pain, Agitation, and Delirium Protocol in the Surgical Intensive Care Unit. AB - BACKGROUND: Society of Critical Care Medicine guidelines recommend the use of pain, agitation, and delirium protocols in the intensive care unit. The feasibility of nurse management of such protocols in the surgical intensive care unit has not been well assessed. OBJECTIVES: To evaluate the percentage of adherent medication interventions for patients assessed by using a pain, sedation, and delirium protocol. METHODS: Data on all adult patients admitted to a surgical intensive care unit from January 2013 through September 2013 who were assessed at least once by using a pain, sedation, and delirium protocol were retrospectively reviewed. Protocol adherence was evaluated for interventions implemented after a nursing assessment. Patients were further divided into 2 groups on the basis of adherence, and achievement of pain and sedation goals was evaluated between groups. RESULTS: Data on 41 patients were included. Of the 603 pain assessments, 422 (70.0%) led to an intervention adherent to the protocol. Of the 249 sedation assessments, 192 (77.1%) led to an adherent intervention. Among patients with 75% or greater adherent pain interventions, all interventions met pain goals with significantly less fentanyl than that used in interventions that did not meet goals. Despite 75% or greater adherence with interventions for sedation assessments, only 8.7% of the interventions met sedation goals. CONCLUSIONS: A nurse-managed pain, agitation, and delirium protocol can be feasibly implemented in a surgical intensive care unit. PMID- 29196586 TI - Implementing a Multicomponent Intervention to Prevent Delirium Among Critically Ill Patients. AB - BACKGROUND: Delirium is common among the critically ill. Nonpharmacologic interventions are reportedly effective in reducing incident delirium, but limited data specific to this population exist. OBJECTIVES: To assess the efficacy and describe the implementation strategy of a multicomponent intervention to prevent delirium in an intensive care unit. METHODS: A before-and-after study was conducted in an intensive care unit between May 2014 through August 2015. Adult participants were enrolled consecutively, excluding only those who refused to participate. Tailored interventions took available evidence into consideration. Components included early mobilization, physical therapy, reorientation, cognitive stimulation, drug reviews, environmental stimulation, avoidance of sensory deprivation, pain control, restraint use avoidance, and family participation. Incident delirium was assessed twice daily using the Confusion Assessment Method for the Intensive Care Unit. Multivariate logistic regression was used to control for confounders. RESULTS: The study included 227 patients (54.7% male; mean [SD] age, 63.3 [18.3] years). Our strategy significantly reduced delirium (from 38% to 24%; relative risk, 0.62; 95% CI, 0.40-0.94; P = .02), an association that remained significant after adjusting for confounders. Adherence rates were more than 85% in all intervention domains (except daily reorientation) that were overseen by health care providers. CONCLUSIONS: The strategy was successful in reducing delirium. Self-removals of invasive implements decreased, an observation that has not been previously described. No difference in mortality rate was seen, as has been reported in other studies. Early participation of the whole team, shared leadership, and the provision of concrete tasks were key to the success of this multicomponent intervention. PMID- 29196587 TI - Perceptions of Family Members, Nurses, and Physicians on Involving Patients' Families in Delirium Prevention. AB - BACKGROUND: Delirium occurs in up to 80% of patients admitted to an intensive care unit. Nonpharmacologic delirium-prevention strategies, which are commonly used by the bedside nurse, have reduced the incidence and duration of delirium in patients in the intensive care unit. With increasing demands on the nurse, strategies such as including the patient's family in delirium prevention activities should be investigated. OBJECTIVE To determine opinions and willingness of health care providers to involve patients' families in nonpharmacologic delirium-prevention activities in the intensive care unit, and of patients' families to be involved. METHODS: Two surveys, one for intensive care unit nurses and physicians and one for patients' families, were developed and administered. The provider survey focused on current delirium-prevention practices and opinions about family involvement. The family survey concentrated on barriers and willingness to participate in prevention activities. RESULTS: Sixty nurses and 58 physicians completed the survey. Most physicians (93%) and all nurses believed families could assist with delirium prevention. Only 50% reported speaking with family members about delirium and delirium prevention. The family survey was completed by 60 family members; 38% reported a provider spoke with them about delirium. Family members reported high levels of comfort in participating in delirium-prevention activities. CONCLUSIONS: Health care providers and family members are supportive of the latter performing delirium prevention activities. Family of patients in the intensive care unit may work collaboratively with nurses to reduce the incidence and duration of delirium in these patients. PMID- 29196588 TI - Understanding Stage II Bidirectional Cavopulmonary Shunts. AB - Despite improvements in surgical technique and medical management, single ventricle lesions remain one of the most challenging congenital heart anomalies to treat, and mortality rates are high. Most infants who have single-ventricle palliation undergo a sequence of surgeries to optimize pulmonary and systemic blood flow. The first surgery to separate pulmonary and systemic blood flow is the bidirectional cavopulmonary shunt. This article describes single-ventricle lesions and gives a basic overview of outcomes and strategies to improve interstage mortality. Preoperative investigations that evaluate stage II candidacy are reviewed along with surgical approaches and postoperative physiology. Although mortality rates are low and decreasing in patients with bidirectional cavopulmonary shunts, morbidity is still a challenge. Nurses must understand the pertinent anatomy and physiology and recognize postoperative complications early in order to reduce morbidity. Postoperative complications, management, outcomes and nursing care are discussed. PMID- 29196584 TI - Family Support During Resuscitation: A Quality Improvement Initiative. AB - BACKGROUND: Despite increasing support for family presence during cardiopulmonary resuscitation, a review of the literature revealed no published protocols or training curricula to guide hospitals in implementing a family support provider role. OBJECTIVES: To develop a curriculum and train dedicated resuscitation team members whose role is to provide family support during in-hospital resuscitation events. METHODS: An interdisciplinary team developed a 4-hour training session for the family support staff. The session included an introduction to the evidence for family presence during resuscitation and local data on resuscitations. The training was composed of 4 sections: (1) clinical aspects of resuscitation, (2) integration into the resuscitation team and steps for providing family support during resuscitation, (3) responding to families in distress, and (4) self-care practices. Before and after the training session, the participants completed surveys of self-rated knowledge and attitudes toward family presence during resuscitation. RESULTS: Fifty-nine social workers and 8 spiritual care providers were trained in 2015. There was a significant increase in all rated aspects of knowledge of the family support role and self-care strategies. CONCLUSION: Through the creation of an interdisciplinary curriculum, an institution can effectively train health care providers in a new resuscitation team role: the family support provider.

PMID- 29196594 TI - Perceptions of Families of Intensive Care Unit Patients Regarding Involvement in Delirium-Prevention Activities: A Qualitative Study. AB - BACKGROUND: Nonpharmacologic delirium-prevention strategies are commonly used in the intensive care unit by bedside nurses. With up to 80% of intensive care unit patients becoming delirious, and lacking treatment options, prevention is key. However, with increasing nurse workloads, innovative delirium-prevention strategies such as involving the patient's family are needed. OBJECTIVE: To gain insight into opinions of patients' families regarding active participation in delirium-prevention activities to inform specific recommendations for involving patients' families in such activities. METHODS: Purposeful sampling was used. Patients' families were contacted to be interviewed about their opinions and attitudes on participation in nonpharmacologic delirium prevention activities while visiting the intensive care unit. An interview guide was created and used to facilitate discussion. Interviews were conducted, transcribed verbatim, and coded by 2 independent coders. Themes were identified, defined, and compared between independent coders; disagreements were resolved by the study team. RESULTS: After 10 interviews were conducted, thematic saturation occurred. Three major themes emerged: (1) consistent family presence and participation in care, (2) improving ease of interactions between family and patient, and (3) delirium education for families. CONCLUSION: Family members want to be involved with care and delirium prevention; however, many times they do not know what to do without the direction of a health care provider. Family members would benefit from open dialogue with the bedside nurse to increase family comfort and involvement in care.

PMID- 29196595 TI - Identifying Information Resources for Patients in the Intensive Care Unit and Their Families. AB - BACKGROUND: Providing information to patients in intensive care units and their families is challenging. Patients often are admitted unexpectedly and experience stress and uncertainty. One source of stress has been identified as unclear, uncoordinated, or inconsistent communication and information. Despite the need for information, no centrally located, easily accessible, standardized intensive care unit education content exists. OBJECTIVE: To identify educational content for patients in the intensive care unit and their families across 4 different hospitals, develop a general content database, and organize the general content into a framework for education of patients and their families. METHODS: Educational content for patients in the intensive care units of 4 participating hospitals was collected and a gap analysis was performed. RESULTS: Key content format and categories were identified. Educational content was organized into an information pathway divided into 3 phases: intensive care unit arrival; understanding the intensive care unit and partnering in care; and intensive care unit transitions. The gap analysis revealed substantial variation in content format and categories. CONCLUSIONS: Structuring a digital learning center using different stages of the patient's stay in the intensive care unit and placing resources in the context of an information pathway can help coordinate education for these patients and their families, and creates a consistent communication guide for clinicians as well. The optimal digital format should be considered in designing the learning center. PMID- 29196597 TI - Testing Serum Batches for Mouse Embryonic Stem Cell Culture. AB - The variability in embryonic stem (ES) cell culture is due primarily to serum. Serum is typically produced in large batches from many animals. However, samples may differ depending on the age and diet of the animals, the country of origin, and other factors creating lot-to-lot variations. Some vendors test FBS lots for compatibility with ES cell culture. Many laboratories prefer to test serum batches themselves to identify the lot giving optimal growth. In this protocol, small quantities of specific serum batches are obtained from different suppliers and tested for their ability to support ES cells in an undifferentiated state. A complete test includes the serum batches' influence on plating efficiency, cell morphology, toxicity, and, if possible, their ability to support generation of chimeras. PMID- 29196598 TI - Preparation of DNA from Embryonic Stem Cells or Other Cultured Cells. AB - Characterization of embryonic stem (ES) cell-mediated genome alterations, including random insertional transgenesis, gene trapping, gene targeting, and site-specific recombinase-mediated changes, is performed mostly at the ES cell level, before the introduction of these alterations into a mouse. A detailed characterization requires a larger amount of DNA than is required for the initial detection of the candidates for the desired alteration. This protocol describes the preparation of DNA from a 10-cm tissue culture plate. The cells are trypsinized and lysed, and DNA is recovered from the lysate by organic extraction followed by ethanol precipitation. PMID- 29196599 TI - Detergent Lysis of Tissue Culture Cells for Immunoprecipitation. AB - This protocol describes the lysis of tissue culture cells for the solubilization of proteins of interest for immunoprecipitation. Upon collection of cells by centrifugation and depending on the use of either Tris- or phosphate-based cell lysis buffers, cells are rinsed, respectively, in either TBS or PBS before lysis. If possible, the pH of the Wash buffer should match that of the Lysis buffer. Adherent cells can be directly lysed on the plate. This is particularly useful upon lysis encompassing mild nonionic detergents, leaving the cytoskeleton intact. Alternatively, adherent cells can be scraped off the plate and directly resuspended in Lysis buffer or Wash buffer for transfer to a tube followed by the addition of Lysis buffer. PMID- 29196600 TI - Detergent Lysis of Animal Tissues for Immunoprecipitation. AB - This protocol details protein extraction from mouse tissues for immunoprecipitation purposes and has been applied for the performance of large scale immunoprecipitations of target proteins from various tissues for the identification of associated proteins by mass spectroscopy. The key factors in performing a successful immunoprecipitation directly relate to the abundance of target protein in a particular tissue type and whether or not the embryonic, newborn, or adult mouse-derived tissues contain fibrous and other insoluble material. Several tissue types, including lung and liver as well as carcinomas, contain significant amounts of fibrous tissue that can interfere with an immunoprecipitation. PMID- 29196601 TI - Immunoprecipitation. AB - This immunoprecipitation protocol details individual steps for the enrichment and purification process of specific proteins from a complex cell lysate using an antibody bound to a solid matrix. Purified antigen(s) can be eluted by various methods, and the resultant protein target can be analyzed and/or identified by numerous assays, including the enzyme-linked immunosorbent assay (ELISA), western blotting, or mass spectrometry. PMID- 29196602 TI - Identification and characterization of a core fucosidase from the bacterium Elizabethkingia meningoseptica. AB - All reported alpha-l-fucosidases catalyze the removal of nonreducing terminal l fucoses from oligosaccharides or their conjugates, while having no capacity to hydrolyze core fucoses in glycoproteins directly. Here, we identified an alpha fucosidase from the bacterium Elizabethkingia meningoseptica with catalytic activity against core alpha-1,3-fucosylated substrates, and we named it core fucosidase I (cFase I). Using site-specific mutational analysis, we found that three acidic residues (Asp-242, Glu-302, and Glu-315) in the predicted active pocket are critical for cFase I activity, with Asp-242 and Glu-315 acting as a pair of classic nucleophile and acid/base residues and Glu-302 acting in an as yet undefined role. These findings suggest a catalytic mechanism for cFase I that is different from known alpha-fucosidase catalytic models. In summary, cFase I exhibits glycosidase activity that removes core alpha-1,3-fucoses from substrates, suggesting cFase I as a new tool for glycobiology, especially for studies of proteins with core fucosylation. PMID- 29196603 TI - Effects of chondroitin sulfate proteoglycan 4 (NG2/CSPG4) on soft-tissue sarcoma growth depend on tumor developmental stage. AB - Sarcomas, and the mesenchymal precursor cells from which they arise, express chondroitin sulfate proteoglycan 4 (NG2/CSPG4). However, NG2/CSPG4's function and its capacity to serve as a therapeutic target in this tumor type are unknown. Here, we used cells from human tumors and a genetically engineered autochthonous mouse model of soft-tissue sarcomas (STSs) to determine NG2/CSPG4's role in STS initiation and growth. Inhibiting NG2/CSPG4 expression in established murine and human STSs decreased tumor volume by almost two-thirds and cell proliferation rate by 50%. NG2/CSPG4 antibody immunotherapy in human sarcomas established as xenografts in mice similarly decreased tumor volume, and expression of a lentivirus blocking NG2/CSPG4 expression inhibited tumor cell proliferation and increased the latency of engraftment. Gene profiling showed that Ng2/Cspg4 deletion altered the expression of genes regulating cell proliferation and apoptosis. Surprisingly, Ng2/Cspg4 deletion at the time of tumor initiation resulted in larger tumors. Gene expression profiling indicated substantial down regulation of insulin-like growth factor binding protein (Igfbp) genes when Ng2/Cspg4 is depleted at tumor initiation, but not when Ng2/Cspg4 is depleted after tumor initiation. Such differences may have clinical significance, as therapeutic targeting of a signaling pathway such as NG2/CSPG4 may have different effects on cell behavior with tumor progression. NG2/CSPG4 depletion has divergent effects, depending on the developmental stage of sarcoma. In established tumors, IGF signaling is active, and NG2 inhibition targets cell proliferation and apoptosis. PMID- 29196604 TI - CaMKII regulates the depalmitoylation and synaptic removal of the scaffold protein AKAP79/150 to mediate structural long-term depression. AB - Both long-term potentiation (LTP) and depression (LTD) of excitatory synapse strength require the Ca2+/calmodulin (CaM)-dependent protein kinase II (CaMKII) and its autonomous activity generated by Thr-286 autophosphorylation. Additionally, LTP and LTD are correlated with dendritic spine enlargement and shrinkage that are accompanied by the synaptic accumulation or removal, respectively, of the AMPA-receptor regulatory scaffold protein A-kinase anchoring protein (AKAP) 79/150. We show here that the spine shrinkage associated with LTD indeed requires synaptic AKAP79/150 removal, which in turn requires CaMKII activity. In contrast to normal CaMKII substrates, the substrate sites within the AKAP79/150 N-terminal polybasic membrane-cytoskeletal targeting domain were phosphorylated more efficiently by autonomous compared with Ca2+/CaM-stimulated CaMKII activity. This unusual regulation was mediated by Ca2+/CaM binding to the substrate sites resulting in protection from phosphorylation in the presence of Ca2+/CaM, a mechanism that favors phosphorylation by prolonged, weak LTD stimuli versus brief, strong LTP stimuli. Phosphorylation by CaMKII inhibited AKAP79/150 association with F-actin; it also facilitated AKAP79/150 removal from spines but was not required for it. By contrast, LTD-induced spine removal of AKAP79/150 required its depalmitoylation on two Cys residues within the N-terminal targeting domain. Notably, such LTD-induced depalmitoylation was also blocked by CaMKII inhibition. These results provide a mechanism how CaMKII can indeed mediate not only LTP but also LTD through regulated substrate selection; however, in the case of AKAP79/150, indirect CaMKII effects on palmitoylation are more important than the effects of direct phosphorylation. Additionally, our results provide the first direct evidence for a function of the well-described AKAP79/150 trafficking in regulating LTD-induced spine shrinkage. PMID- 29196605 TI - Isoform-independent and -dependent phosphorylation of microtubule-associated protein tau in mouse brain during postnatal development. AB - Tau is a microtubule (MT)-associated protein that regulates MT dynamics in the axons of neurons. Tau binds to MTs via its C-terminal MT-binding repeats. There are two types of tau, those with three (3R) or four (4R) MT-binding repeats; 4R tau has a stronger MT-stabilizing activity than 3R tau. The MT-stabilizing activity of tau is regulated by phosphorylation. Interestingly, both the isoform and phosphorylation change at the time of neuronal circuit formation during postnatal development; highly phosphorylated 3R tau is replaced with 4R tau, which is less phosphorylated. However, it is not known how the transition of the isoforms and phosphorylation are regulated. Here, we addressed this question using developing mouse brains. Detailed analysis of developing brains revealed that the switch from 3R to 4R tau occurred during postnatal day 9 (P9) to P18 under the same time course as the conversion of phosphorylation from high to low. However, hypothyroidism, which is known to delay brain development, delayed the timing of tau dephosphorylation but not the exchange of isoforms, indicating that isoform switching and phosphorylation are not necessarily linked. Furthermore, we confirmed this finding by using mouse brains that expressed a single isoform of human tau. Human tau, either 3R or 4R, reduced phosphorylation levels during development even though the isoform did not change. We also found that 3R tau and 4R tau were phosphorylated differently in vivo even at the same developmental days. These results show for the first time that the phosphorylation and isoform alteration of tau are regulated differently during mouse development. PMID- 29196606 TI - Control of endothelial cell tube formation by Notch ligand intracellular domain interactions with activator protein 1 (AP-1). AB - Notch signaling is a ubiquitous signal transduction pathway found in most if not all metazoan cell types characterized to date. It is indispensable for cell differentiation as well as tissue growth, tissue remodeling, and apoptosis. Although the canonical Notch signaling pathway is well characterized, accumulating evidence points to the existence of multiple, less well-defined layers of regulation. In this study, we investigated the function of the intracellular domain (ICD) of the Notch ligand Delta-like 4 (DLL4). We provide evidence that the DLL4 ICD is required for normal DLL4 subcellular localization. We further show that it is cleaved and interacts with the JUN proto-oncogene, which forms part of the activator protein 1 (AP-1) transcription factor complex. Mechanistically, the DLL4 ICD inhibited JUN binding to DNA and thereby controlled the expression of JUN target genes, including DLL4 Our work further demonstrated that JUN strongly stimulates endothelial cell tube formation and that DLL4 constrains this process. These results raise the possibility that Notch/DLL4 signaling is bidirectional and suggest that the DLL4 ICD could represent a point of cross-talk between Notch and receptor tyrosine kinase (RTK) signaling. PMID- 29196608 TI - Rhesus monkey TRIM5alpha protein SPRY domain contributes to AP-1 activation. AB - TRIM5alpha is an important host restriction factor that could potently block retrovirus infection. The SPRY domain of TRIM5alpha mediates post-entry restriction by recognition of and binding to the retroviral capsid. Human TRIM5alpha also functions as an innate immune sensor to activate AP-1 and NF kappaB signaling, which subsequently restrict virus replication. Previous studies have shown that the AP-1 and NF-kappaB signaling activation relies on the RING motif of TRIM5alpha. In this study, we have demonstrated that the SPRY domain is essential for rhesus macaque TRIM5alpha to activate AP-1 but not NF-kappaB signaling. The AP-1 activation mainly depends on all of the beta-sheet barrel on SPRY structure of TRIM5alpha. Furthermore, the SPRY-mediated auto-ubiquitination of TRIM5alpha is required for AP-1 activation. This study reports that rhesus macaque TRIM5alpha mainly undergoes Lys27-linked and Met1-linked auto polyubiquitination. Finally, we found that the TRIM5alpha signaling function was positively correlated with its retroviral restriction activity. This study discovered an important role of the SPRY domain in immune signaling and antiviral activity and further expanded our knowledge of the antiviral mechanism of TRIM5alpha. PMID- 29196607 TI - Blue light-excited LOV1 and LOV2 domains cooperatively regulate the kinase activity of full-length phototropin2 from Arabidopsis. AB - Phototropin2 (phot2) is a blue-light (BL) receptor that regulates BL-dependent activities for efficient photosynthesis in plants. phot2 comprises two BL receiving light-oxygen-voltage-sensing domains (LOV1 and LOV2) and a kinase domain. BL-excited LOV2 is thought to be primarily responsible for the BL dependent activation of the kinase. However, the molecular mechanisms by which small BL-induced conformational changes in the LOV2 domain are transmitted to the kinase remain unclear. Here, we used full-length wild-type and mutant phot2 proteins from Arabidopsis to study their molecular properties in the dark and under BL irradiation. Phosphorylation assays and absorption measurements indicated that the LOV1 domain assists the thermal relaxation of BL-excited LOV2 and vice versa. Using small-angle X-ray scattering and electron microscopy, we observed that phot2 forms a dimer and has a rod shape with a maximum length of 188 A and a radius of gyration of 44 A. Under BL, phot2 displayed large conformational changes that bent the rod shape. By superimposing the crystal structures of the LOV1 dimer, LOV2, and a homology model of the kinase to the observed changes, we inferred that the BL-dependent change consisted of positional shifts of both LOV2 and the kinase relative to LOV1. Furthermore, phot2 mutants lacking the photocycle in LOV1 or LOV2 still exhibited conformational changes under BL, suggesting that LOV1 and LOV2 cooperatively contribute to the conformational changes that activate the kinase. These results suggest that BL-activated LOV1 contributes to the kinase activity of phot2. We discuss the possible intramolecular interactions and signaling mechanisms in phot2. PMID- 29196609 TI - MicroRNA-based therapeutics in cardiovascular disease: screening and delivery to the target. AB - MicroRNAs (miRNAs) are small non-coding RNAs of ~22 nucleotides, which have increasingly been recognized as potent post-transcriptional regulators of gene expression. MiRNA targeting is defined by the complementarities between positions 2-8 of miRNA 5'-end with generally the 3'-untranslated region of target mRNAs (messenger RNAs). The capacity of miRNAs to simultaneously inhibit many different mRNAs allows for an amplification of biological responses. Hence, miRNAs are extremely attractive targets for therapeutic regulation in several diseases, including cardiovascular. Novel approaches are emerging to identify the miRNA functions in cardiovascular biology processes and to improve miRNA delivery in the heart and vasculature. In the present study, we provide an overview of current studies of miRNA functions in cardiovascular cells by the use of high content screening. We also discuss the challenge to achieve a safe and targeted delivery of miRNA therapeutics in cardiovascular cells. PMID- 29196610 TI - Single-molecule live-cell imaging of bacterial DNA repair and damage tolerance. AB - Genomic DNA is constantly under threat from intracellular and environmental factors that damage its chemical structure. Uncorrected DNA damage may impede cellular propagation or even result in cell death, making it critical to restore genomic integrity. Decades of research have revealed a wide range of mechanisms through which repair factors recognize damage and co-ordinate repair processes. In recent years, single-molecule live-cell imaging methods have further enriched our understanding of how repair factors operate in the crowded intracellular environment. The ability to follow individual biochemical events, as they occur in live cells, makes single-molecule techniques tremendously powerful to uncover the spatial organization and temporal regulation of repair factors during DNA repair reactions. In this review, we will cover practical aspects of single molecule live-cell imaging and highlight recent advances accomplished by the application of these experimental approaches to the study of DNA-repair processes in prokaryotes. PMID- 29196611 TI - Cell signaling abnormalities in cardiomyopathy caused by lamin A/C gene mutations. AB - Mutations in the lamin A/C gene (LMNA) encoding intermediate filament proteins associated with the inner nuclear membrane cause diseases known as laminopathies. Most LMNA mutations cause dilated cardiomyopathy with variable skeletal muscular dystrophy. Cell signaling abnormalities have been discovered in hearts of mouse models of cardiomyopathy caused by LMNA mutations that contribute to pathogenesis. These include abnormally increased signaling by extracellular signal-regulated kinase 1 and kinase 2 and other mitogen-activated protein kinases, protein kinase B/mammalian target of rapamycin complex 1 and transforming growth factor-beta. Preclinical research suggests that specific inhibitors of these abnormally activated cell signaling pathways may be useful in treating human patients with this disease. PMID- 29196612 TI - Homeopathic Treatment of Vitiligo: A Report of Fourteen Cases. AB - BACKGROUND Vitiligo, also known as leukoderma, is an autoimmune skin condition that results in the loss of melanin pigment. Vitiligo is not a rare condition but is difficult to treat and is associated with psychological distress. CASE REPORT A series of 14 cases of vitiligo are presented that were treated with individualized homeopathic remedies that were based on plant, animal, or mineral compounds. There were 13 women and one man in the case series, with a mean age 29.8 years, and a mean follow-up from treatment of 58 months. The mean time between the onset of the appearance of vitiligo and the first consultation at our clinic was 96 months. Homeopathic treatment for patients is holistic and was performed on an individualized basis as described in this case series. Photographic images of the skin are presented before and after treatment. CONCLUSIONS In 14 patients with vitiligo treated with individualized homeopathy, the best results were achieved in the patients who were treated in the early stages of the disease. We believe that homeopathy may be effective in the early stages of vitiligo, but large controlled clinical studies are needed in this area. PMID- 29196613 TI - Protective Effect of Luteolin Against Renal Ischemia/Reperfusion Injury via Modulation of Pro-Inflammatory Cytokines, Oxidative Stress and Apoptosis for Possible Benefit in Kidney Transplant. AB - BACKGROUND The acceptances and long-term outcomes of the renal transplantations are seriously jeopardized by inflammatory responses and damage to tissues. The present study intended to explicate the pharmacological effect of luteolin (LT) in renal ischemia/reperfusion (I/R) injury and the possible mechanism of action of LT. MATERIAL AND METHODS The effect of LT on the level of interleukin (IL) 1beta, IL-6, and tumor necrosis factor (TNF)-alpha in the homogenates of kidney tissues of male Swiss albino mice was determined after I/R injury. The effect of LT on MDA (malondialdehyde), SOD (superoxide dismutase), CAT (catalase), and glutathione were also identified by enzyme assay. In addition, Western blotting was used to determine the level of Bcl-2, Bax, and caspase-3 in the presence of LT. RESULTS The results showed that LT caused significant reduction in the level of TNF-alpha, IL-1beta, and IL-6 compared to the I/R group without LT (p>0.05). To further confirm this, the efficacy of LT on the histopathology of I/R injured renal tissues was studied. It was found that LT restored cellular viability of damaged renal tissue. This observation was further confirmed by TUNEL assay, where it was found that LT caused considerable reduction in the population of apoptotic cells. LT pretreatment significantly increased Bcl-2 expression and reduced the level of Bax expression together with a reduction in the level of caspase-3 expression. CONCLUSIONS Luteolin showed its effect by interfering and attenuating a number of pathways, including pathways for inflammation and apoptosis in renal tissues. PMID- 29196615 TI - Expressed fusion gene landscape and its impact in multiple myeloma. AB - Multiple myeloma is a plasma cell malignancy characterized by recurrent IgH translocations and well described genomic heterogeneity. Although transcriptome profiles in multiple myeloma has been described, landscape of expressed fusion genes and their clinical impact remains unknown. To provide a comprehensive and detailed fusion gene cartography and suggest new mechanisms of tumorigenesis in multiple myeloma, we performed RNA sequencing in a cohort of 255 newly diagnosed and homogeneously treated multiple myeloma patients with long follow-up. Here, we report that patients have on average 5.5 expressed fusion genes. Kappa and lambda light chains and IgH genes are main partners in a third of all fusion genes. We also identify recurrent fusion genes that significantly impact both progression free and overall survival and may act as drivers of the disease. Lastly, we find a correlation between the number of fusions, the age of patients and the clinical outcome, strongly suggesting that genomic instability drives prognosis of the disease. PMID- 29196616 TI - 17beta-Estradiol sensitizes ovarian surface epithelium to transformation by suppressing Disabled-2 expression. AB - Estrogen replacement therapy increases the risk of human ovarian cancer and exogenous estradiol accelerates the onset of ovarian cancer in mouse models. This study uses primary cultures of mouse ovarian surface epithelium (OSE) to demonstrate that one possible mechanism by which estrogen accelerates the initiation of ovarian cancer is by up-regulation of microRNA-378 via the ESR1 pathway to result in the down-regulation of a tumour suppressor called Disabled-2 (Dab2). Estrogen suppression of Dab2 was reproducible in vivo and across many cell types including mouse oviductal epithelium and primary cultures of human ovarian cancer cells. Suppression of Dab2 resulted in increased proliferation, loss of contact inhibition, morphological dysplasia, and resistance to oncogene induced senescence - all factors that can sensitize OSE to transformation. Given that DAB2 is highly expressed in healthy human OSE and is absent in the majority of ovarian tumours, this study has taken the first steps to provide a mechanistic explanation for how estrogen therapy may play a role in the initiation of ovarian cancer. PMID- 29196614 TI - Genome-wide association study of classical Hodgkin lymphoma identifies key regulators of disease susceptibility. AB - Several susceptibility loci for classical Hodgkin lymphoma have been reported. However, much of the heritable risk is unknown. Here, we perform a meta-analysis of two existing genome-wide association studies, a new genome-wide association study, and replication totalling 5,314 cases and 16,749 controls. We identify risk loci for all classical Hodgkin lymphoma at 6q22.33 (rs9482849, P = 1.52 * 10 8) and for nodular sclerosis Hodgkin lymphoma at 3q28 (rs4459895, P = 9.43 * 10 17), 6q23.3 (rs6928977, P = 4.62 * 10-11), 10p14 (rs3781093, P = 9.49 * 10-13), 13q34 (rs112998813, P = 4.58 * 10-8) and 16p13.13 (rs34972832, P = 2.12 * 10-8). Additionally, independent loci within the HLA region are observed for nodular sclerosis Hodgkin lymphoma (rs9269081, HLA-DPB1*03:01, Val86 in HLA-DRB1) and mixed cellularity Hodgkin lymphoma (rs1633096, rs13196329, Val86 in HLA-DRB1). The new and established risk loci localise to areas of active chromatin and show an over-representation of transcription factor binding for determinants of B-cell development and immune response. PMID- 29196617 TI - Retarding oxidation of copper nanoparticles without electrical isolation and the size dependence of work function. AB - Copper nanoparticles (CuNPs) are attractive as a low-cost alternative to their gold and silver analogues for numerous applications, although their potential has hardly been explored due to their higher susceptibility to oxidation in air. Here we show the unexpected findings of an investigation into the correlation between the air-stability of CuNPs and the structure of the thiolate capping ligand; of the eight different ligands screened, those with the shortest alkyl chain, (CH2)2-, and a hydrophilic carboxylic acid end group are found to be the most effective at retarding oxidation in air. We also show that CuNPs are not etched by thiol solutions as previously reported, and address the important fundamental question of how the work function of small supported metal particles scales with particle size. Together these findings set the stage for greater utility of CuNPs for emerging electronic applications. PMID- 29196619 TI - Opposite effects of Activin type 2 receptor ligands on cardiomyocyte proliferation during development and repair. AB - Zebrafish regenerate damaged myocardial tissue very effectively. Hence, insights into the molecular networks underlying zebrafish heart regeneration might help develop alternative strategies to restore human cardiac performance. While TGF beta signaling has been implicated in zebrafish cardiac regeneration, the role of its individual ligands remains unclear. Here, we report the opposing expression response during zebrafish heart regeneration of two genes, mstnb and inhbaa, which encode TGF-beta family ligands. Using gain-of-function (GOF) and loss-of function (LOF) approaches, we show that these ligands mediate inverse effects on cardiac regeneration and specifically on cardiomyocyte (CM) proliferation. Notably, we find that Inhbaa functions as a CM mitogen and that its overexpression leads to accelerated cardiac recovery and scar clearance after injury. In contrast, mstnb GOF and inhbaa LOF both lead to unresolved scarring after cardiac injury. We further show that Mstnb and Inhbaa inversely control Smad2 and Smad3 transcription factor activities through alternate Activin type 2 receptors. PMID- 29196618 TI - The Kalanchoe genome provides insights into convergent evolution and building blocks of crassulacean acid metabolism. AB - Crassulacean acid metabolism (CAM) is a water-use efficient adaptation of photosynthesis that has evolved independently many times in diverse lineages of flowering plants. We hypothesize that convergent evolution of protein sequence and temporal gene expression underpins the independent emergences of CAM from C3 photosynthesis. To test this hypothesis, we generate a de novo genome assembly and genome-wide transcript expression data for Kalanchoe fedtschenkoi, an obligate CAM species within the core eudicots with a relatively small genome (~260 Mb). Our comparative analyses identify signatures of convergence in protein sequence and re-scheduling of diel transcript expression of genes involved in nocturnal CO2 fixation, stomatal movement, heat tolerance, circadian clock, and carbohydrate metabolism in K. fedtschenkoi and other CAM species in comparison with non-CAM species. These findings provide new insights into molecular convergence and building blocks of CAM and will facilitate CAM-into-C3 photosynthesis engineering to enhance water-use efficiency in crops. PMID- 29196620 TI - Emphatic visualization of sphingomyelin-rich domains by inter-lipid FRET imaging using fluorescent sphingomyelins. AB - Imaging the distribution of sphingomyelin (SM) in membranes is an important issue in lipid-raft research. Recently we developed novel fluorescent SM analogs that exhibit partition and dynamic behaviors similar to native SM, and succeeded in visualizing lateral domain-segregation between SM-rich liquid-ordered (Lo) and SM poor liquid-disordered (Ld) domains. However, because the fluorescent contrast between these two domains depends directly on their partition ratio for the fluorescent SMs, domain-separation becomes indeterminate when the distribution difference is not great enough. In this study, we propose the use of inter-lipid Forster resonance energy transfer (FRET) imaging between fluorescent SMs to enhance the contrast of the two domains in cases in which the inter-domain difference in SM distribution is inadequate for conventional monochromic imaging. Our results demonstrate that inter-lipid FRET intensity was significantly higher in the Lo domain than in the Ld domain, resulting in a clear and distinguishable contrast between the two domains even in poorly phase-separated giant unilamellar vesicles. In addition, we show that inter-lipid FRET imaging is useful for selective visualization of highly condensed assemblies and/or clusters of SM molecules in living cell membranes. Thus, the inter-lipid FRET imaging technique can selectively emphasize the SM-condensed domains in both artificial and biological membranes.

AB - Many organisms rely on antimicrobial peptides (AMPs) as a first line of defense against pathogens. In general, most AMPs are thought to kill bacteria by binding to and disrupting cell membranes. However, certain AMPs instead appear to inhibit biomacromolecule synthesis, while causing less membrane damage. Despite an unclear understanding of mechanism(s), there is considerable interest in mimicking AMPs with stable, synthetic molecules. Antimicrobial N-substituted glycine (peptoid) oligomers ("ampetoids") are structural, functional and mechanistic analogs of helical, cationic AMPs, which offer broad-spectrum antibacterial activity and better therapeutic potential than peptides. Here, we show through quantitative studies of membrane permeabilization, electron microscopy, and soft X-ray tomography that both AMPs and ampetoids trigger extensive and rapid non-specific aggregation of intracellular biomacromolecules that correlates with microbial death. We present data demonstrating that ampetoids are "fast killers", which rapidly aggregate bacterial ribosomes in vitro and in vivo. We suggest intracellular biomass flocculation is a key mechanism of killing for cationic, amphipathic AMPs, which may explain why most AMPs require micromolar concentrations for activity, show significant selectivity for killing bacteria over mammalian cells, and finally, why development of resistance to AMPs is less prevalent than developed resistance to conventional antibiotics.

A genetic algorithm is applied over many generations whereas machine learning works by applying feedback until the system meets a performance threshold. These methods have been previously combined, particularly in artificial neural networks using an external objective feedback mechanism. We adapt this approach to Markov Brains, which are evolvable networks of probabilistic and deterministic logic gates. Prior to this work MB could only adapt from one generation to the other, so we introduce feedback gates which augment their ability to learn during their lifetime. We show that Markov Brains can incorporate these feedback gates in such a way that they do not rely on an external objective feedback signal, but instead can generate internal feedback that is then used to learn. This results in a more biologically accurate model of the evolution of learning, which will enable us to study the interplay between evolution and learning and could be another step towards autonomously learning machines.

AB - Inflammasomes are involved in gut homeostasis and inflammatory pathologies, but the role of NLRP3 inflammasome in these processes is not well understood. Cryopyrin-associated periodic syndrome (CAPS) patients with NLRP3 mutations have autoinflammation in skin, joints, and eyes, but not in the intestine. Here we show that the intestines of CAPS model mice carrying an Nlrp3 R258W mutation maintain homeostasis in the gut. Additionally, such mice are strongly resistant to experimental colitis and colorectal cancer; this is mainly through a remodelled gut microbiota with enhanced anti-inflammatory capacity due to increased induction of regulatory T cells (Tregs). Mechanistically, NLRP3R258W functions exclusively in the lamina propria mononuclear phagocytes to directly enhance IL-1beta but not IL-18 secretion. Increased IL-1beta boosts local antimicrobial peptides to facilitate microbiota remodelling. Our data show that NLRP3R258W-induced remodelling of the gut microbiota, induces local Tregs to maintain homeostasis and compensate for otherwise-detrimental intestinal inflammation. PMID- 29196625 TI - Territory holders and non-territory holders in Ayu fish coexist only in the population growth process due to hysteresis. AB - Ayu fish form feeding territories during a non-breeding (growing) season. When the density of the fish increases, phases gradually change. In the early growing season, all fish can hold territories at low density. Once all territory sites are occupied, newcomers become floaters. As the density further increases, territory holders have to spend much more time in defending their own territory and lose the time to feed on algae. Eventually, all fish give up their own territories and then form a school. In contrast, when the density decreases, territories are directly reformed from the school. In short, ayu fish exhibit a different transition, called hysteresis, where the two transitions occur widely apart from each other. The dynamics of this intrinsic phenomena has not been demonstrated in previous studies. We develop a rate equation to describe the population dynamics within territorial competition. Our model successfully reproduces territorial hysteresis and indicates that territory holders and floaters can coexist only in the process of population growth. Moreover, we also find that the two critical densities of territorial hysteresis are conspicuously different from each other when the increase of the density of floaters sharply influences (step-function-like) the territories. PMID- 29196624 TI - RNA-seq of serial kidney biopsies obtained during progression of chronic kidney disease from dogs with X-linked hereditary nephropathy. AB - Dogs with X-linked hereditary nephropathy (XLHN) have a glomerular basement membrane defect that leads to progressive juvenile-onset renal failure. Their disease is analogous to Alport syndrome in humans, and they also serve as a good model of progressive chronic kidney disease (CKD). However, the gene expression profile that affects progression in this disease has only been partially characterized. To help fill this gap, we used RNA sequencing to identify differentially expressed genes (DEGs), over-represented pathways, and upstream regulators that contribute to kidney disease progression. Total RNA from kidney biopsies was isolated at 3 clinical time points from 3 males with rapidly progressing CKD, 3 males with slowly-progressing CKD, and 2 age-matched controls. We identified 70 DEGs by comparing rapid and slow groups at specific time points. Based on time course analysis, 1,947 DEGs were identified over the 3 time points revealing upregulation of inflammatory pathways: integrin signaling, T cell activation, and chemokine and cytokine signaling pathways. T cell infiltration was verified by immunohistochemistry. TGF-beta1 was identified as the primary upstream regulator. These results provide new insights into the underlying molecular mechanisms of disease progression in XLHN, and the identified DEGs can be potential biomarkers and therapeutic targets translatable to all CKDs. PMID- 29196626 TI - Identification of Borrelia protein candidates in mouse skin for potential diagnosis of disseminated Lyme borreliosis. AB - In vector-borne diseases, the skin plays an essential role in the transmission of vector-borne pathogens between the vertebrate host and blood-feeding arthropods and in pathogen persistence. Borrelia burgdorferi sensu lato is a tick-borne bacterium that causes Lyme borreliosis (LB) in humans. This pathogen may establish a long-lasting infection in its natural vertebrate host where it can persist in the skin and some other organs. Using a mouse model, we demonstrate that Borrelia targets the skin regardless of the route of inoculation, and can persist there at low densities that are difficult to detect via qPCR, but that were infective for blood-feeding ticks. Application of immunosuppressive dermocorticoids at 40 days post-infection (PI) significantly enhanced the Borrelia population size in the mouse skin. We used non-targeted (Ge-LC-MS/MS) and targeted (SRM-MS) proteomics to detect several Borrelia-specific proteins in the mouse skin at 40 days PI. Detected Borrelia proteins included flagellin, VlsE and GAPDH. An important problem in LB is the lack of diagnosis methods capable of detecting active infection in humans suffering from disseminated LB. The identification of Borrelia proteins in skin biopsies may provide new approaches for assessing active infection in disseminated manifestations. PMID- 29196627 TI - Pathologic N0 Status in Clinical T1N0M0 Lung Adenocarcinoma is Predictable by the Solid Component Proportion with Quantitative CT Number Analysis. AB - Correctly predicting pathologic regional node-negative (pN0) disease in patients with lung cancer before operation may avoid unnecessary mediastinal lymph node dissection (MLND). In this study, we analyze the value of the radiographic and histopathological features of primary tumors for predicting pN0 status in cT1N0M0 lung adenocarcinoma and to establish an optimal surgical strategy for avoiding MLND in cT1N0M0 lung adenocarcinoma patients. We retrospectively investigated the histopathological and radiographic data of 348 surgically resected cT1N0M0 lung adenocarcinoma patients with systematic lymph node dissection from January 2005 to December 2012. Histopathological features and radiographic features were analyzed. Multivariable analysis was used to identify significant predictors of pN0 disease. Our results showed that pN0 disease was detected in 306 patients (87.9%) among the 348 patients with cT1N0M0 lung adenocarcinoma. A decreasing trend of the pN0 disease proportion was observed with both increasing histological grade and decreased differentiation (P < 0.001). In multivariable analysis, the solid component proportion was a significant predictor of pN0 disease. Among 110 patients with a solid component proportion of no more than 21.3%, mediastinal lymph node involvement was not observed. Patients who meet this criterion may be successfully managed with lung resection without MLND. PMID- 29196628 TI - Multi-physics interactions drive VEGFR2 relocation on endothelial cells. AB - Vascular Endothelial Growth Factor Receptor-2 (VEGFR2) is a pro-angiogenic receptor, expressed on endothelial cells (ECs). Although biochemical pathways that follow the VEGFR2 activation are well established, knowledge about the dynamics of receptors on the plasma membrane remains limited. Ligand stimulation induces the polarization of ECs and the relocation of VEGFR2, either in cell protrusions or in the basal aspect in cells plated on ligand-enriched extracellular matrix (ECM). We develop a mathematical model in order to simulate the relocation of VEGFR2 on the cell membrane during the mechanical adhesion of cells onto a ligand-enriched substrate. Co-designing the in vitro experiments with the simulations allows identifying three phases of the receptor dynamics, which are controlled respectively by the high chemical reaction rate, by the mechanical deformation rate, and by the diffusion of free receptors on the membrane. The identification of the laws that regulate receptor polarization opens new perspectives toward developing innovative anti-angiogenic strategies through the modulation of EC activation. PMID- 29196629 TI - Immune and Imaging Correlates of Mild Cognitive Impairment Conversion to Alzheimer's Disease. AB - Amnestic mild cognitive impairment (aMCI) conversion to Alzheimer's disease (AD) is seen in a sizable portion of aMCI patients; correlates predicting such conversion are poorly defined but neuroinflammation and the reactivation of chronic viral infections are suspected to play a role in this phenomenon. We analyzed these aspects in two homogeneous groups of aMCI who did or did not convert to AD over a 24-months period. Results showed that at baseline in those aMCI individuals who did not convert to AD: 1) Abeta1-42 stimulated production of the pro-inflammatory cytokines IL6 and IL1beta by CD14+ cells was significantly reduced (p = 0.01), 2) CD14+/IL-33+ cells were increased (p = 0.0004); 3) MFI of TLR8 and TLR9 was significantly increased, and 4) better preserved hippocampus volumes were observed and correlated with IL33+/CD14+ cells. Notably, Abeta1-42 stimulated production of the antiviral cytokine IFN-lambda was increased as well in non-AD converters, although with a borderline statistical significance (p = 0.05). Data herein indicating that proinflammatory cytokines are reduced, whereas IFN-lambda production and TLR8 and 9 MFI are augmented in those aMCI in whom AD conversion is not observed suggest that the ability to mount stronger antiviral response within an antiiflammatory milieu associates with lack of AD conversion. PMID- 29196630 TI - An engineered opsin monomer scrambles phospholipids. AB - The G protein-coupled receptor opsin is a phospholipid scramblase that facilitates rapid transbilayer phospholipid exchange in liposomes. The mechanism by which opsin scrambles lipids is unknown. It has been proposed that lipid translocation may occur at protein-protein interfaces of opsin dimers. To test this possibility, we rationally engineered QUAD opsin by tryptophan substitution of four lipid-facing residues in transmembrane helix 4 (TM4) that is known to be important for dimerization. Atomistic molecular dynamics simulations of wild type and QUAD opsins combined with continuum modeling revealed that the tryptophan substitutions lower the energetically unfavorable residual hydrophobic mismatch between TM4 and the membrane, reducing the drive of QUAD opsin to dimerize. We purified thermostable wild type and QUAD opsins, with or without a SNAP tag for fluorescence labeling. Single molecule fluorescence measurements of purified SNAP tagged constructs revealed that both proteins are monomers. Fluorescence-based activity assays indicated that QUAD opsin is a fully functional scramblase. However, unlike wild type opsin which dimerizes en route to insertion into phospholipid vesicles, QUAD opsin reconstitutes as a monomer. We conclude that an engineered opsin monomer can scramble phospholipids, and that the lipid-exposed face of TM4 is unlikely to contribute to transbilayer phospholipid exchange. PMID- 29196631 TI - Conservation of folding and association within a family of spidroin N-terminal domains. AB - Web spiders synthesize silk fibres, nature's toughest biomaterial, through the controlled assembly of fibroin proteins, so-called spidroins. The highly conserved spidroin N-terminal domain (NTD) is a pH-driven self-assembly device that connects spidroins to super-molecules in fibres. The degree to which forces of self-assembly is conserved across spider glands and species is currently unknown because quantitative measures are missing. Here, we report the comparative investigation of spidroin NTDs originating from the major ampullate glands of the spider species Euprosthenops australis, Nephila clavipes, Latrodectus hesperus, and Latrodectus geometricus. We characterized equilibrium thermodynamics and kinetics of folding and self-association using dynamic light scattering, stopped-flow fluorescence and circular dichroism spectroscopy in combination with thermal and chemical denaturation experiments. We found cooperative two-state folding on a sub-millisecond time scale through a late transition state of all four domains. Stability was compromised by repulsive electrostatic forces originating from clustering of point charges on the NTD surface required for function. pH-driven dimerization proceeded with characteristic fast kinetics yielding high affinities. Results showed that energetics and kinetics of NTD self-assembly are highly conserved across spider species despite the different silk mechanical properties and web geometries they produce. PMID- 29196632 TI - Automated VSS-based Burn Scar Assessment using Combined Texture and Color Features of Digital Images in Error-Correcting Output Coding. AB - Assessment of burn scars is an important study in both medical research and clinical settings because it can help determine response to burn treatment and plan optimal surgical procedures. Scar rating has been performed using both subjective observations and objective measuring devices. However, there is still a lack of consensus with respect to the accuracy, reproducibility, and feasibility of the current methods. Computerized scar assessment appears to have potential for meeting such requirements but has been rarely found in literature. In this paper an image analysis and pattern classification approach for automating burn scar rating based on the Vancouver Scar Scale (VSS) was developed. Using the image data of pediatric patients, a rating accuracy of 85% was obtained, while 92% and 98% were achieved for the tolerances of one VSS score and two VSS scores, respectively. The experimental results suggest that the proposed approach is very promising as a tool for clinical burn scar assessment that is reproducible and cost-effective. PMID- 29196633 TI - Lysophosphatidylcholine acyltransferase 4 is involved in chondrogenic differentiation of ATDC5 cells. AB - Glycerophospholipids have important structural and functional roles in cells and are the main components of cellular membranes. Glycerophospholipids are formed via the de novo pathway (Kennedy pathway) and are subsequently matured in the remodeling pathway (Lands' cycle). Lands' cycle consists of two steps: deacylation of phospholipids by phospholipases A2 and reacylation of lysophospholipids by lysophospholipid acyltransferases (LPLATs). LPLATs play key roles in the maturation and maintenance of the fatty acid composition of biomembranes, and cell differentiation. We examined whether LPLATs are involved in chondrogenic differentiation of ATDC5 cells, which can differentiate into chondrocytes. Lysophosphatidylcholine acyltransferase 4 (LPCAT4) mRNA expression and LPCAT enzymatic activity towards 18:1-, 18:2-, 20:4-, and 22:6-CoA increased in the late stage of chondrogenic differentiation, when mineralization occurred. LPCAT4 knockdown decreased mRNA and protein levels of chondrogenic markers as well as Alcian blue staining intensity and alkaline phosphatase activity in ATDC5 cells. These results suggest that LPCAT4 plays important roles during the transition of chondrocytes into hypertrophic chondrocytes and/or a mineralized phenotype. PMID- 29196634 TI - Rational engineering of a native hyperthermostable lactonase into a broad spectrum phosphotriesterase. AB - The redesign of enzyme active sites to alter their function or specificity is a difficult yet appealing challenge. Here we used a structure-based design approach to engineer the lactonase SsoPox from Sulfolobus solfataricus into a phosphotriesterase. The five best variants were characterized and their structure was solved. The most active variant, alphasD6 (V27A-Y97W-L228M-W263M) demonstrates a large increase in catalytic efficiencies over the wild-type enzyme, with increases of 2,210-fold, 163-fold, 58-fold, 16-fold against methyl parathion, malathion, ethyl-paraoxon, and methyl-paraoxon, respectively. Interestingly, the best mutants are also capable of degrading fensulfothion, which is reported to be an inhibitor for the wild-type enzyme, as well as others that are not substrates of the starting template or previously reported W263 mutants. The broad specificity of these engineered variants makes them promising candidates for the bioremediation of organophosphorus compounds. Analysis of their structures reveals that the increase in activity mainly occurs through the destabilization of the active site loop involved in substrate binding, and it has been observed that the level of disorder correlates with the width of the enzyme specificity spectrum. This finding supports the idea that active site conformational flexibility is essential to the acquisition of broader substrate specificity. PMID- 29196635 TI - MALE STERILE6021 (MS6021) is required for the development of anther cuticle and pollen exine in maize. AB - The anther cuticle and pollen wall function as physical barriers that protect genetic material from various environmental stresses. The anther cuticle is composed of wax and cutin, the pollen wall includes exine and intine, and the components of the outer exine are collectively called sporopollenin. Other than cuticle wax, cutin and sporopollenin are biopolymers compounds. The precise constituents and developmental mechanism of these biopolymeric are poorly understood. Here, we reported a complete male sterile mutant, male sterile6021, in maize. The mutant displayed a smooth anther surface and irregular pollen wall formation before anthesis, and its tapetum was degraded immaturely. Gas chromatography-mass spectrometry analysis revealed a severe reduction of lipid derivatives in the mutant anther. We cloned the gene by map based cloning. It encoded a fatty acyl carrier protein reductase that was localized in plastids. Expression analysis indicated that MS6021 was mainly expressed in the tapetum and microspore after the microspore was released from the tetrad. Functional complementation of the orthologous Arabidopsis mutant demonstrated that MS6021 is conserved between monocots and dicots and potentially even in flowering plants. MS6021 plays a conserved, essential role in the successful development of anther cuticle and pollen exine in maize. PMID- 29196636 TI - Modeling of the jasmonate signaling pathway in Arabidopsis thaliana with respect to pathophysiology of Alternaria blight in Brassica. AB - The productivity of Oilseed Brassica, one of the economically important crops of India, is seriously affected by the disease, Alternaria blight. The disease is mainly caused by two major necrotrophic fungi, Alternaria brassicae and Alternaria brassicicola which are responsible for significant yield losses. Till date, no resistant source is available against Alternaria blight, hence plant breeding methods can not be used to develop disease resistant varieties. Jasmonate mediated signalling pathway, which is known to play crucial role during defense response against necrotrophs, could be strengthened in Brassica plants to combat the disease. Since scanty information is available in Brassica-Alternaria pathosystems at molecular level therefore, in the present study efforts have been made to model jasmonic acid pathway in Arabidopsis thaliana to simulate the dynamic behaviour of molecular species in the model. Besides, the developed model was also analyzed topologically for investigation of the hubs node. COI1 is identified as one of the promising candidate genes in response to Alternaria and other linked components of plant defense mechanisms against the pathogens. The findings from present study are therefore informative for understanding the molecular basis of pathophysiology and rational management of Alternaria blight for securing food and nutritional security. PMID- 29196637 TI - Influence of the electrolyte's pH on the properties of electrochemically deposited hydroxyapatite coating on additively manufactured Ti64 alloy. AB - Properties of the hydroxyapatite obtained by electrochemical assisted deposition (ED) are dependent on several factors including deposition temperature, electrolyte pH and concentrations, applied potential. All of these factors directly influence the morphology, stoichiometry, crystallinity, electrochemical behaviour, and particularly the coating thickness. Coating structure together with surface micro- and nano-scale topography significantly influence early stages of the implant bio-integration. The aim of this study is to analyse the effect of pH modification on the morphology, corrosion behaviour and in vitro bioactivity and in vivo biocompatibility of hydroxyapatite prepared by ED on the additively manufactured Ti64 samples. The coatings prepared in the electrolytes with pH = 6 have predominantly needle like morphology with the dimensions in the nanometric scale (~30 nm). Samples coated at pH = 6 demonstrated higher protection efficiency against the corrosive attack as compared to the ones coated at pH = 5 (~93% against 89%). The in vitro bioactivity results indicated that both coatings have a greater capacity of biomineralization, compared to the uncoated Ti64. Somehow, the coating deposited at pH = 6 exhibited good corrosion behaviour and high biomineralization ability. In vivo subcutaneous implantation of the coated samples into the white rats for up to 21 days with following histological studies showed no serious inflammatory process. PMID- 29196638 TI - Uncovering different states of topological defects in schlieren textures of a nematic liquid crystal. AB - Topological defects are ubiquitously found in physical systems and therefore have been an important research subject of not only condensed matter physics but also cosmology. However, their fine structures remain elusive because of the microscopic scales involved. In the case of a liquid crystal, optical microscopy, although routinely used for the identification of liquid crystal phases and associated defects, does not have resolution high enough to distinguish fine structures of topological defects. Here we show that polarised and fluorescence microscopy, with the aid of numerical calculations on the orientational order and resulting image distortions, can uncover the structural states of topological defects with strength m = +/-1 in a thin cell of a nematic liquid crystal. Particularly, defects with m = +1 exhibit four different states arising from chiral symmetry breaking and up-down symmetry breaking. Our results demonstrate that optical microscopy is still a powerful tool to identify fine states of liquid crystalline defects. PMID- 29196640 TI - Image Fiber-Based Miniature Suspended Solid Sensor with High Accuracy and a Large Dynamic Range. AB - An image fiber-based miniature suspended solid sensor has been demonstrated. The diameter of the sensor is only a few millimeters. A superhydrophobic material is coated on the end of the image fiber to avoid the adsorption of suspended solids and bubbles. Multiple parameters, including mass concentration, morphology and particle sizes of suspended solids, can be visually measured in real time. Dynamic ranges of 0 ~100 kg/m3, full range accuracies of +/-20/00 and a response time of 0.05 s were experimentally realized for the mass concentration measurements. Determinations of particle sizes of the suspended solids are also presented by means of digital image processing. This new technique will significantly advance ultralow-intrusion measurements in studies on the dynamics of suspended solids. PMID- 29196639 TI - Meta analysis: HPV and p16 pattern determines survival in patients with HNSCC and identifies potential new biologic subtype. AB - Consistent discrepancies in the p16/HPV-positivity have been observed in head and neck squamous cell carcinoma (HNSCC). It is therefore questionable, if all HPV+ and/or p16+ tested cancers are HPV-driven. Patients down-staged according to the HPV-dependant TNM are at risk for undertreatment and data in clinical trials may be skewed due to false patient inclusion. We performed a meta-analysis to classify clinical outcomes of the distinct subgroups with combined p16 and HPV detection. 25 out of 1677 publications fulfilled the inclusion criteria. The proportion of the subgroups was 35.6% for HPV+/p16+, 50.4% for HPV-/p16-, 6.7% for HPV-/p16+ and 7.3% for HPV+/P16-. The HPV+/p16+ subgroup had a significantly improved 5-year overall-survival (OS) and disease-free-survival in comparison to others both for HNSCC and oropharyngeal cancers. The 5-year OS of the HPV-/p16+ HNSCC was intermediate while HPV+/p16- and HPV-/p16- had the shortest survival outcomes. The clearly distinct survival of HPV-/p16+ cancers may characterize a new relevant HPV-independent subtype yet to be biologically characterized. The possibility also exists that in some HPV+/p16+ cancers HPV is an innocent bystander and p16 is independently positive. Therefore, in perspective, HPV testing should distinguish between bystander HPV and truly HPV-driven cancers to avoid potential undertreatment in HPV+ but non-HPV-driven HNSCC. PMID- 29196641 TI - Simultaneous realization of high sensing sensitivity and tunability in plasmonic nanostructures arrays. AB - A plasmonic nanostructure (PNS) which integrates metallic and dielectric media within a single structure has been shown to exhibit specific plasmonic properties which are considered useful in refractive index (RI) sensor applications. In this paper, the simultaneous realization of sensitivity and tunability of the optical properties of PNSs consisting of alternative Ag and dielectric of nanosphere/nanorod array have been proposed and compared by using three dimensional finite element method. The proposed system can support plasmonic hybrid modes and the localized surface plasmonic resonances and cavity plasmonic resonances within the individual PNS can be excited by the incident light. The proposed PNSs can be operated as RI sensor with a sensitivity of 500 nm/RIU (RIU = refractive index unit) ranging from UV to the near-infrared. In addition, a narrow bandwidth and nearly zero transmittance along with a high absorptance can be achieved by a denser PNSs configuration in the unit cell of PNS arrays. We have demonstrated the number of modes sustained in the PNS system, as well as, the near-field distribution can be tailored by the dielectric media in PNSs. PMID- 29196642 TI - A chalcohalide glass/alloy based Ag+ ion - selective electrode with nanomolar detection limit. AB - In this paper, a silver ion-selective electrode material with lower detection limit is presented. The electrode is based on 22.5As2S3-22.5Ag2S-55AgCl chalcohalide glass membranes. The low detection limit decreases from the micromolar range of the original Ag2S-As2S3 electrode to the nanomolar level (1.89 nM) by introducing AgCl. The addition of AgCl increases the conductivity of the glasses and improves the analytical properties of electrodes because of the joint effects of Ag+ and Cl- on network structure of the glass. The super Nernstian response behavior was observed for the partially crystallized electrode. The electrode containing AgCl also possesses a high selectivity (except for Hg2+), fast response and good stability. PMID- 29196643 TI - Blood Serum Calorimetry Indicates the Chemotherapeutic Efficacy in Lung Cancer Treatment. AB - Chemotherapy is a primary treatment for the metastatic lung cancer patients. To select the most effective combination of drugs, we need an efficient way of assessing tumor response. Here, we showed that differential scanning calorimetry (DSC) analysis of blood serum proteins could reveal the patient response to the treatment. If chemotherapy is effective, serum proteins DSC curve of non-small cellular lung cancer (NSCLC) case is similar to the those of the healthy individuals. If treatment fails, notable changes occur in the DSC profile of NSCLC patient's blood serum. Our preliminary work illustrates how thermal analysis of changes in the heat capacity of blood serum proteins can provide an insight into patient response to chemotherapy - the essential information for any successive lung cancer treatment. PMID- 29196644 TI - Adaptive laboratory evolution of Corynebacterium glutamicum towards higher growth rates on glucose minimal medium. AB - In this work, we performed a comparative adaptive laboratory evolution experiment of the important biotechnological platform strain Corynebacterium glutamicum ATCC 13032 and its prophage-free variant MB001 towards improved growth rates on glucose minimal medium. Both strains displayed a comparable adaptation behavior and no significant differences in genomic rearrangements and mutation frequencies. Remarkably, a significant fitness leap by about 20% was observed for both strains already after 100 generations. Isolated top clones (UBw and UBm) showed an about 26% increased growth rate on glucose minimal medium. Genome sequencing of evolved clones and populations resulted in the identification of key mutations in pyk (pyruvate kinase), fruK (1-phosphofructokinase) and corA encoding a Mg2+ importer. The reintegration of selected pyk and fruK mutations resulted in an increased glucose consumption rate and ptsG expression causative for the accelerated growth on glucose minimal medium, whereas corA mutations improved growth under Mg2+ limiting conditions. Overall, this study resulted in the identification of causative key mutations improving the growth of C. glutamicum on glucose. These identified mutational hot spots as well as the two evolved top strains, UBw and UBm, represent promising targets for future metabolic engineering approaches. PMID- 29196645 TI - Small molecule screen in embryonic zebrafish using modular variations to target segmentation. AB - Small molecule in vivo phenotypic screening is used to identify drugs or biological activities by directly assessing effects in intact organisms. However, current screening designs may not exploit the full potential of chemical libraries due to false negatives. Here, we demonstrate a modular small molecule screen in embryonic zebrafish that varies concentration, genotype and timing to target segmentation disorders, birth defects that affect the spinal column. By testing each small molecule in multiple interrelated ways, this screen recovers compounds that a standard screening design would have missed, increasing the hit frequency from the chemical library three-fold. We identify molecular pathways and segmentation phenotypes, which we share in an open-access annotated database. These hits provide insight into human vertebral segmentation disorders and myopathies. This modular screening strategy is applicable to other developmental questions and disease models, highlighting the power of relatively small chemical libraries to accelerate gene discovery and disease study. PMID- 29196646 TI - Early-Mid Pleistocene genetic differentiation and range expansions as exemplified by invasive Eurasian Bunias orientalis (Brassicaceae) indicates the Caucasus as key region. AB - Turkish Warty cabbage, Bunias orientalis L. (Brassicaceae) is a perennial herb known for its 250 years of invasion history into Europe and worldwide temperate regions. Putative centers of origin were debated to be located in Turkey, the Caucasus or Eastern Europe. Based on the genetic variation from the nuclear and plastid genomes, we identified two major gene pools in the Caucasian-Irano Turanian region and close to the Northern Caucasus, respectively. These gene pools are old and started to diverge and expand approximately 930 kya in the Caucasus. Pleistocene glaciation and deglaciation cycles favoured later expansion of a European gene pool 230 kya, which was effectively separated from the Caucasian-Irano-Turanian gene pool. Although the European gene pool is genetically less diverse, it has largely served as source for colonization of Western and Northern Europe in modern times with rare observations of genetic contributions from the Caucasian-Irano-Turanian gene pool such as in North-East America. This study largely utilized herbarium material to take advantage of a biodiversity treasure trove providing biological material and also giving access to detailed collection information. PMID- 29196648 TI - Sequestosome1/p62 protects mouse embryonic fibroblasts against low-dose methylercury-induced cytotoxicity and is involved in clearance of ubiquitinated proteins. AB - Methylmercury (MeHg) is a widely distributed environmental pollutant that causes a series of cytotoxic effects. However, molecular mechanisms underlying MeHg toxicity are not fully understood. Here, we report that sequestosome1/p62 protects mouse embryonic fibroblasts (MEFs) against low-dose MeHg cytotoxicity via clearance of MeHg-induced ubiquitinated proteins. p62 mRNA and protein expression in MEFs were temporally induced by MeHg exposure p62-deficient MEFs exhibited higher sensitivity to MeHg exposure compared to their wild-type (WT) counterparts. An earlier and higher level of accumulation of ubiquitinated proteins was detected in p62-deficient cells compared with WT MEFs. Confocal microscopy revealed that p62 and ubiquitinated proteins co-localized in the perinuclear region of MEFs following MeHg treatment. Further analysis of MEFs revealed that ubiquitinated proteins co-localized with LC3-positive puncta upon co-treatment with MeHg and chloroquine, an autophagy inhibitor. In contrast, there was minimal co-localization in p62-deficient MEFs. The present study, for the first time, examined the expression and distribution of p62 and ubiquitinated proteins in cells exposed to low-dose MeHg. Our findings suggest that p62 is crucial for cytoprotection against MeHg-induced toxicity and is required for MeHg induced ubiquitinated protein clearance.

AB - Subchondral bone has been identified as an attractive target for KOA. To determine whether a minimally invasive micro-scaffolds could be used to induce regeneration of knee subchondral bone lesions, and to examine the protective effect of subchondral bone regeneration on upper cartilage, a ready-to-use injectable treatment with nanohydroxyapatite-chitosan-gelatin micro-scaffolds (HaCGMs) is proposed. Human-infrapatellar-fat-pad-derived adipose stem cells (IPFP-ASCs) were used as a cellular model to examine the osteo-inductivity and biocompatibility of HaCGMs, which were feasibly obtained with potency for multi potential differentiations. Furthermore, a subchondral bone lesion model was developed to mimic the necrotic region removing performed by surgeons before sequestrectomy. HaCGMs were injected into the model to induce regeneration of subchondral bone. HaCGMs exhibited desirable swelling ratios, porosity, stiffness, and bioactivity and allowed cellular infiltration. Eight weeks after treatment, assessment via X-ray imaging, micro-CT imaging, and histological analysis revealed that rabbits treated with HaCGMs had better subchondral bone regeneration than those not treated. Interestingly, rabbits in the HaCGM treatment group also exhibited improved reservation of upper cartilage compared to those in other groups, as shown by safranin O-fast green staining. Present study provides an in-depth demonstration of injectable HaCGM-based regenerative therapy, which may provide an attractive alternative strategy for treating KOA.

AB - Deletion of Glu139 in beta-tropomyosin caused by a point mutation in TPM2 gene is associated with cap myopathy characterized by high myofilament Ca2+-sensitivity and muscle weakness. To reveal the mechanism of these disorders at molecular level, mobility and spatial rearrangements of actin, tropomyosin and the myosin heads at different stages of actomyosin cycle in reconstituted single ghost fibres were investigated by polarized fluorescence microscopy. The mutation did not alter tropomyosin's affinity for actin but increased strongly the flexibility of tropomyosin and kept its strands near the inner domain of actin. The ability of troponin to switch actin monomers "on" and "off" at high and low Ca2+, respectively, was increased, and the movement of tropomyosin towards the blocked position at low Ca2+ was inhibited, presumably causing higher Ca2+-sensitivity. The mutation decreased also the amount of the myosin heads which bound strongly to actin at high Ca2+ and increased the number of these heads at relaxation; this may contribute to contractures and muscle weakness. PMID- 29196650 TI - A polar bundle of flagella can drive bacterial swimming by pushing, pulling, or coiling around the cell body. AB - Bacteria swim in sequences of straight runs that are interrupted by turning events. They drive their swimming locomotion with the help of rotating helical flagella. Depending on the number of flagella and their arrangement across the cell body, different run-and-turn patterns can be observed. Here, we present fluorescence microscopy recordings showing that cells of the soil bacterium Pseudomonas putida that are decorated with a polar tuft of helical flagella, can alternate between two distinct swimming patterns. On the one hand, they can undergo a classical push-pull-push cycle that is well known from monopolarly flagellated bacteria but has not been reported for species with a polar bundle of multiple flagella. Alternatively, upon leaving the pulling mode, they can enter a third slow swimming phase, where they propel themselves with their helical bundle wrapped around the cell body. A theoretical estimate based on a random-walk model shows that the spreading of a population of swimmers is strongly enhanced when cycling through a sequence of pushing, pulling, and wrapped flagellar configurations as compared to the simple push-pull-push pattern.

AB - Growth and contraction of ecosystem engineers, such as trees, influence ecosystem structure and function. On coral reefs, methods to measure small changes in the structure of microhabitats, driven by growth of coral colonies and contraction of skeletons, are extremely limited. We used 3D reconstructions to quantify changes in the external structure of coral colonies of tabular Acropora spp., the dominant habitat-forming corals in shallow exposed reefs across the Pacific. The volume and surface area of live colonies increased by 21% and 22%, respectively, in 12 months, corresponding to a mean annual linear extension of 5.62 cm yr-1 (+/ 1.81 SE). The volume and surface area of dead skeletons decreased by 52% and 47%, respectively, corresponding to a mean decline in linear extension of -29.56 cm yr 1 (+/-7.08 SE), which accounted for both erosion and fragmentation of dead colonies. This is the first study to use 3D photogrammetry to assess fine-scale structural changes of entire individual colonies in situ, quantifying coral growth and contraction. The high-resolution of the technique allows for detection of changes on reef structure faster than other non-intrusive approaches. These results improve our capacity to measure the drivers underpinning ecosystem biodiversity, status and trajectory. PMID- 29196652 TI - Vacuum level dependent photoluminescence in chemical vapor deposition-grown monolayer MoS 2. AB - The stronger photoluminescence (PL) in chemical vapor deposition (CVD) grown monolayer MoS2 has been attributed to its high crystal quality compared with that in mechanically exfoliated (ME) crystal, which is contrary to the cognition that the ME crystal usually have better crystal quality than that of CVD grown one and it is expected with a better optical quality. In this report, the reason of abnormally strong PL spectra in CVD grown monolayer crystal is systematically investigated by studying the in-situ opto-electrical exploration at various environments for both of CVD and ME samples. High resolution transmission electron microscopy is used to investigate their crystal qualities. The stronger PL in CVD grown crystal is due to the high p-doping effect of adsorbates induced rebalance of exciton/trion emission. The first principle calculations are carried out to explore the interaction between adsorbates in ambient and defects sites in MoS2, which is consistent to the experimental phenomenon and further confirm our proposed mechanisms. PMID- 29196653 TI - New energy with ZnS: novel applications for a standard transparent compound. AB - We revise the electronic and optical properties of ZnS on the basis of first principles simulations, in view of novel routes for optoelectronic and photonic devices, such as transparent conductors and plasmonic applications. In particular, we consider doping effects, as induced by Al and Cu. It is shown that doping ZnS with Al imparts a n-character and allows for a plasmonic activity in the mid-IR that can be exploited for IR metamaterials, while Cu doping induces a spin dependent p-type character to the ZnS host, opening the way to the engineering of transparent p-n junctions, p-type transparent conductive materials and spintronic applications. The possibility of promoting the wurtzite lattice, presenting a different symmetry with respect to the most stable and common zincblende structure, is explored. Homo- and heterojunctions to twin ZnO are discussed as a possible route to transparent metamaterial devices for communications and energy. PMID- 29196654 TI - Cascading collapse of online social networks. AB - Online social networks have increasing influence on our society, they may play decisive roles in politics and can be crucial for the fate of companies. Such services compete with each other and some may even break down rapidly. Using social network datasets we show the main factors leading to such a dramatic collapse. At early stage mostly the loosely bound users disappear, later collective effects play the main role leading to cascading failures. We present a theory based on a generalised threshold model to explain the findings and show how the collapse time can be estimated in advance using the dynamics of the churning users. Our results shed light to possible mechanisms of instabilities in other competing social processes. PMID- 29196655 TI - Systematic identification of novel regulatory interactions controlling biofilm formation in the bacterium Escherichia coli. AB - Here, we investigated novel interactions of three global regulators of the network that controls biofilm formation in the model bacterium Escherichia coli using computational network analysis, an in vivo reporter assay and physiological validation experiments. We were able to map critical nodes that govern planktonic to biofilm transition and identify 8 new regulatory interactions for CRP, IHF or Fis responsible for the control of the promoters of rpoS, rpoE, flhD, fliA, csgD and yeaJ. Additionally, an in vivo promoter reporter assay and motility analysis revealed a key role for IHF as a repressor of cell motility through the control of FliA sigma factor expression. This investigation of first stage and mature biofilm formation indicates that biofilm structure is strongly affected by IHF and Fis, while CRP seems to provide a fine-tuning mechanism. Taken together, the analysis presented here shows the utility of combining computational and experimental approaches to generate a deeper understanding of the biofilm formation process in bacteria. PMID- 29196656 TI - Development of a plasmid free CRISPR-Cas9 system for the genetic modification of Mucor circinelloides. AB - Mucor circinelloides and other members of Mucorales are filamentous fungi, widely used as model organisms in basic and applied studies. Although genetic manipulation methods have been described for some Mucoral fungi, construction of stable integrative transformants by homologous recombination has remained a great challenge in these organisms. In the present study, a plasmid free CRISPR-Cas9 system was firstly developed for the genetic modification of a Mucoral fungus. The described method offers a rapid but robust tool to obtain mitotically stable mutants of M. circinelloides via targeted integration of the desired DNA. It does not require plasmid construction and its expression in the recipient organism. Instead, it involves the direct introduction of the guide RNA and the Cas9 enzyme and, in case of homology directed repair (HDR), the template DNA into the recipient strain. Efficiency of the method for non-homologous end joining (NHEJ) and HDR was tested by disrupting two different genes, i.e. carB encoding phytoene dehydrogenase and hmgR2 encoding 3-hydroxy-3-methylglutaryl-CoA reductase, of M. circinelloides. Both NHEJ and HDR resulted in stable gene disruption mutants. While NHEJ caused extensive deletions upstream from the protospacer adjacent motif, HDR assured the integration of the deletion cassette at the targeted site. PMID- 29196657 TI - Alternative activation generates IL-10 producing type 2 innate lymphoid cells. AB - Type 2 innate lymphoid cells (ILC2) share cytokine and transcription factor expression with CD4+ Th2 cells, but functional diversity of the ILC2 lineage has yet to be fully explored. Here, we show induction of a molecularly distinct subset of activated lung ILC2, termed ILC210. These cells produce IL-10 and downregulate some pro-inflammatory genes. Signals that generate ILC210 are distinct from those that induce IL-13 production, and gene expression data indicate that an alternative activation pathway leads to the generation of ILC210. In vivo, IL-2 enhances ILC210 generation and is associated with decreased eosinophil recruitment to the lung. Unlike most activated ILC2, the ILC210 population contracts after cessation of stimulation in vivo, with maintenance of a subset that can be recalled by restimulation, analogous to T-cell effector cell and memory cell generation. These data demonstrate the generation of a previously unappreciated IL-10 producing ILC2 effector cell population. PMID- 29196658 TI - Estrogen receptor 1 (ESR1) regulates VEGFA in adipose tissue. AB - Vascular endothelial growth factor A (VEGFA) is a key factor in the regulation of angiogenesis in adipose tissue. Poor vascularization during adipose tissue proliferation causes fibrosis and local inflammation, and is associated with insulin resistance. It is known that 17-beta estradiol (E2) regulates adipose tissue function and VEGFA expression in other tissues; however, the ability of E2 to regulate VEGFA in adipose tissue is currently unknown. In this study, we showed that, in 3T3-L1 cells, E2 and the estrogen receptor 1 (ESR1) agonist PPT induced VEGFA expression, while ESR1 antagonist (MPP), and selective knockdown of ESR1 using siRNA decreased VEGFA and prevented the ability of E2 to modulate its expression. Additionally, we found that E2 and PPT induced the binding of hypoxia inducible factor 1 alpha subunit (HIF1A) in the VEGFA gene promoter. We further found that VEGFA expression was lower in inguinal and gonadal white adipose tissues of ESR1 total body knockout female mice compared to wild type mice. In conclusion, our data provide evidence of an important role for E2/ESR1 in modulating adipose tissue VEGFA, which is potentially important to enhance angiogenesis, reduce inflammation and improve adipose tissue function. PMID- 29196659 TI - Rational design and dynamics of self-propelled colloidal bead chains: from rotators to flagella. AB - The quest for designing new self-propelled colloids is fuelled by the demand for simple experimental models to study the collective behaviour of their more complex natural counterparts. Most synthetic self-propelled particles move by converting the input energy into translational motion. In this work we address the question if simple self-propelled spheres can assemble into more complex structures that exhibit rotational motion, possibly coupled with translational motion as in flagella. We exploit a combination of induced dipolar interactions and a bonding step to create permanent linear bead chains, composed of self propelled Janus spheres, with a well-controlled internal structure. Next, we study how flexibility between individual swimmers in a chain can affect its swimming behaviour. Permanent rigid chains showed only active rotational or spinning motion, whereas longer semi-flexible chains showed both translational and rotational motion resembling flagella like-motion, in the presence of the fuel. Moreover, we are able to reproduce our experimental results using numerical calculations with a minimal model, which includes full hydrodynamic interactions with the fluid. Our method is general and opens a new way to design novel self propelled colloids with complex swimming behaviours, using different complex starting building blocks in combination with the flexibility between them. PMID- 29196660 TI - Transcriptome analysis of watermelon (Citrullus lanatus) fruits in response to Cucumber green mottle mosaic virus (CGMMV) infection. AB - Cucumber green mottle mosaic virus (CGMMV) belongs to the Tobamovirus genus and is a major global plant virus on cucurbit plants. It causes severe disease symptoms on infected watermelon plants (Citrullus lanatus), particularly inducing fruit decay. However, little is known about the molecular mechanism of CGMMV induced watermelon fruit decay. For this study, comparative analysis of transcriptome profiles of CGMMV-inoculated and mock-inoculated watermelon fruits were conducted via RNA-Seq. A total of 1,621 differently expressed genes (DEGs) were identified in CGMMV-inoculated watermelon, among which 1,052 were up regulated and 569 were down-regulated. Functional annotation analysis showed that several DEGs were involved in carbohydrate metabolism, hormone biosynthesis and signaling transduction, secondary metabolites biosynthesis, and plant-pathogen interactions. We furthermore found that some DEGs were related to cell wall components and photosynthesis, which may directly be involve in the development of the symptoms associated with diseased watermelons. To confirm the RNA-Seq data, 15 DEGs were selected for gene expression analysis by qRT-PCR. The results showed a strong correlation between these two sets of data. Our study identified many candidate genes for further functional studies during CGMMV-watermelon interactions, and will furthermore help to clarify the understanding of pathogenic mechanism underlying CGMMV infection in cucurbit plants. PMID- 29196661 TI - fMRI Investigation on Gradual Change of Awareness States in Implicit Sequence Learning. AB - Awareness of implicit knowledge is a changing process. Previous studies have examined brain activation patterns corresponding to the start and end stages of implicit learning, but failed to reveal the gradual changing course of awareness in implicit learning. The present study explored brain activation changes corresponding to different awareness states elicited by two different stimulus onset asynchrony (SOA, 850 ms and 1350 ms) over the whole course of implicit sequence learning (i.e., divided into three phases), by using a process dissociation procedure (PDP) paradigm and the technique of functional magnetic resonance imaging (fMRI). In the results, it was found that the 850 ms SOA elicited primarily an awareness state of unconsciousness, under which the frontal lobe was significantly activated during the early phase of implicit sequence learning, with its activation levels correlated positively to consciousness levels. In contrast, the 1350 ms SOA triggered predominantly an awareness state of consciousness, under which the activation levels of the inferior parietal lobule correlated positively to consciousness levels during the middle phase, and positively to consciousness levels as well as negatively to unconsciousness levels during the late phase of implicit sequence learning. Overall, the frontal lobe and inferior parietal lobule were found to play critical roles in mediating awareness states over the course of implicit sequence learning. PMID- 29196662 TI - Toehold-enhanced LNA probes for selective pull down and single-molecule analysis of native chromatin. AB - The organization of DNA into chromatin is thought to regulate gene expression in eukaryotes. To study its structure in vitro, there is a need for techniques that can isolate specific chromosomal loci of natively assembled chromatin. Current purification methods often involve chemical cross-linking to preserve the chromatin composition. However, such cross-linking may affect the native structure. It also impedes single molecule force spectroscopy experiments, which have been instrumental to probe chromatin folding. Here we present a method for the incorporation of affinity tags, such as biotin, into native nucleoprotein fragments based on their DNA sequence, and subsequent single molecule analysis by magnetic tweezers. DNA oligos with several Locked Nucleic Acid (LNA) nucleotides are shown to selectively bind to target DNA at room temperature, mediated by a toehold end in the target, allowing for selective purification of DNA fragments. The stability of the probe-target hybrid is sufficient to withstand over 65 pN of force. We employ these probes to obtain force-extension curves of native chromatin fragments of the 18S ribosomal DNA from the yeast Saccharomyces cerevisiae. These experiments yield valuable insights in the heterogeneity in structure and composition of natively assembled chromatin at the single-molecule level. PMID- 29196663 TI - A Ser75-to-Asp phospho-mimicking mutation in Src accelerates ageing-related loss of retinal ganglion cells in mice. AB - Src knockout mice show no detectable abnormalities in central nervous system (CNS) post-mitotic neurons, likely reflecting functional compensation by other Src family kinases. Cdk1- or Cdk5-dependent Ser75 phosphorylation in the amino terminal Unique domain of Src, which shares no homology with other Src family kinases, regulates the stability of active Src. To clarify the roles of Src Ser75 phosphorylation in CNS neurons, we established two types of mutant mice with mutations in Src: phospho-mimicking Ser75Asp (SD) and non-phosphorylatable Ser75Ala (SA). In ageing SD/SD mice, retinal ganglion cell (RGC) number in whole retinas was significantly lower than that in young SD/SD mice in the absence of inflammation and elevated intraocular pressure, resembling the pathogenesis of progressive optic neuropathy. By contrast, SA/SA mice and wild-type (WT) mice exhibited no age-related RGC loss. The age-related retinal RGC number reduction was greater in the peripheral rather than the mid-peripheral region of the retina in SD/SD mice. Furthermore, Rho-associated kinase activity in whole retinas of ageing SD/SD mice was significantly higher than that in young SD/SD mice. These results suggest that Src regulates RGC survival during ageing in a manner that depends on Ser75 phosphorylation. PMID- 29196664 TI - The origin of human handedness and its role in pre-birth motor control. AB - The vast majority of humans are right-handed, but how and when this bias emerges during human ontogenesis is still unclear. We propose an approach that explains postnatal handedness starting from 18 gestational weeks using a kinematic analysis of different fetal arm movements recorded during ultrasonography. Based on the hand dominance reported postnatally at age 9, the fetuses were classified as right-handed (86%) or left-handed, in line with population data. We revealed that both right-handed and left-handed fetuses were faster to reach to targets requiring greater precision (i.e., eye and mouth), with their dominant (vs. non dominant) hand. By using either movement times or deceleration estimates, handedness can be inferred with a classification accuracy ranging from 89 to 100% from gestational week 18. The reliability of this inference hints to the yet unexplored potential of standard ultrasonography to advance our understanding of prenatal life. PMID- 29196665 TI - Antibunching-like behavior of mesoscopic light. AB - We present the implementation of a compact setup for the generation of sub Poissonian states of light exhibiting the analogous of antibunching behavior in the so-called mesoscopic intensity domain. In the scheme, the idler arm of a pulsed multi-mode twin-beam state is directly measured by a photon-number resolving detector, whereas the signal arm is divided at a balanced beam splitter, at whose outputs other two photon-number-resolving detectors measure the number of photons. The three detectors measure synchronous with each laser pulse. Due to the nonclassical correlations in the twin beam, when a given value of photons is measured in the idler arm, the conditional states obtained in post processing at the two beam-splitter outputs are nonclassical, showing lower-than one values of the Fano factor and of the photon autocorrelation coefficient. The possibility to engineer sub-Poissonian states nearly approaching the Fock state with one photon is also addressed. PMID- 29196666 TI - Sigma frequency dependent motor learning in Williams syndrome. AB - There are two basic stages of fine motor learning: performance gain might occur during practice (online learning), and improvement might take place without any further practice (offline learning). Offline learning, also called consolidation, has a sleep-dependent stage in terms of both speed and accuracy of the learned movement. Sleep spindle or sigma band characteristics affect motor learning in typically developing individuals. Here we ask whether the earlier found, altered sigma activity in a neurodevelopmental disorder (Williams syndrome, WS) predicts motor learning. TD and WS participants practiced in a sequential finger tapping (FT) task for two days. Although WS participants started out at a lower performance level, TD and WS participants had a comparable amount of online and offline learning in terms of the accuracy of movement. Spectral analysis of WS sleep EEG recordings revealed that motor accuracy improvement is intricately related to WS-specific NREM sleep EEG features in the 8-16 Hz range profiles: higher 11-13.5 Hz z-transformed power is associated with higher offline FT accuracy improvement; and higher oscillatory peak frequencies are associated with lower offline accuracy improvements. These findings indicate a fundamental relationship between sleep spindle (or sigma band) activity and motor learning in WS. PMID- 29196667 TI - A multidisciplinary approach to study the reproductive biology of wild prawns. AB - This work aims to provide deeper knowledge on reproductive biology of P. kerathurus in a multidisciplinary way. Upon 789 examined females, 285 were found inseminated. The logistic equation enabled to estimate the size at first maturity at 30.7 mm CL for female. The Gono-Somatic Index (GSI) showed a pronounced seasonality, ranged from 0.80 +/- 0.34 to 11.24 +/- 5.72. Histological analysis highlighted five stages of ovarian development. Gonadal fatty acids analysis performed with gas chromatograph evidenced a pronounced seasonal variation; total lipids varied from 1.7% dry weight (dw) in Winter, to 7.2% dw in Summer. For the first time, a chemometric approach (Principal Component Analysis) was applied to relate GSI with total lipid content and fatty acid composition of gonads. The first two components (PC1 and PC2) showed that seasonality explained about 84% of the variability of all data set. In particular, in the period February-May, lipids were characterized by high PUFAs content, that were probably utilized during embryogenesis as energy source and as constituent of the cell membranes. During the summer season, gonads accumulated saturated FAs, that will be used during embryogenesis and early larval stages, while in the cold season total lipids decreased drastically and the gonad reached a quiescent state. PMID- 29196668 TI - Adrenergic receptor agonists induce the differentiation of pluripotent stem cell derived hepatoblasts into hepatocyte-like cells. AB - Current induction methods of hepatocytes from human induced pluripotent stem cells (hiPSCs) are neither low cost nor stable. By screening a chemical library of 1,120 bioactive compounds and known drugs, we identified the alpha1-adrenergic receptor agonist methoxamine hydrochloride as a small molecule that promotes the differentiation of hiPSC-derived hepatoblasts into ALBUMIN+ hepatocyte-like cells. Other alpha1-adrenergic receptor agonists also induced the differentiation of hepatocyte-like cells, and an alpha1-receptor antagonist blocked the hepatic inducing activity of methoxamine hydrochloride and that of the combination of hepatocyte growth factor (HGF) and Oncostatin M (OsM), two growth factors often used for the induction of hepatoblasts into hepatocyte-like cells. We also confirmed that treatment with methoxamine hydrochloride activates the signal transducer and activator of transcription 3 (STAT3) pathway downstream of IL-6 family cytokines including OsM. These findings allowed us to establish hepatic differentiation protocols for both mouse embryonic stem cells (mESCs) and hiPSCs using small molecules at the step from hepatoblasts into hepatocyte-like cells. The results of the present study suggest that alpha1-adrenergic agonists induce hepatocyte-like cells by working downstream of HGF and OsM to activate STAT3.

PMID- 29196670 TI - Mutational analysis of TSC1 and TSC2 genes in Tuberous Sclerosis Complex patients from Greece. AB - Tuberous sclerosis complex (TSC) is a rare autosomal dominant disorder causing benign tumors in the brain and other vital organs. The genes implicated in disease development are TSC1 and TSC2. Here, we have performed mutational analysis followed by a genotype-phenotype correlation study based on the clinical characteristics of the affected individuals. Twenty unrelated probands or families from Greece have been analyzed, of whom 13 had definite TSC, whereas another 7 had a possible TSC diagnosis. Using direct sequencing, we have identified pathogenic mutations in 13 patients/families (6 in TSC1 and 7 in TSC2), 5 of which were novel. The mutation identification rate for patients with definite TSC was 85%, but only 29% for the ones with a possible TSC diagnosis. Multiplex ligation-dependent probe amplification (MLPA) did not reveal any genomic rearrangements in TSC1 and TSC2 in the samples with no mutations identified. In general, TSC2 disease was more severe than TSC1, with more subependymal giant cell astrocytomas and angiomyolipomas, higher incidence of pharmacoresistant epileptic seizures, and more severe neuropsychiatric disorders. To our knowledge, this is the first comprehensive TSC1 and TSC2 mutational analysis carried out in TSC patients in Greece. PMID- 29196671 TI - Concurrent structural and biophysical traits link with immunoglobulin light chains amyloid propensity. AB - Light chain amyloidosis (AL), the most common systemic amyloidosis, is caused by the overproduction and the aggregation of monoclonal immunoglobulin light chains (LC) in target organs. Due to genetic rearrangement and somatic hypermutation, virtually, each AL patient presents a different amyloidogenic LC. Because of such complexity, the fine molecular determinants of LC aggregation propensity and proteotoxicity are, to date, unclear; significantly, their decoding requires investigating large sets of cases. Aiming to achieve generalizable observations, we systematically characterised a pool of thirteen sequence-diverse full length LCs. Eight amyloidogenic LCs were selected as responsible for severe cardiac symptoms in patients; five non-amyloidogenic LCs were isolated from patients affected by multiple myeloma. Our comprehensive approach (consisting of spectroscopic techniques, limited proteolysis, and X-ray crystallography) shows that low fold stability and high protein dynamics correlate with amyloidogenic LCs, while hydrophobicity, structural rearrangements and nature of the LC dimeric association interface (as observed in seven crystal structures here presented) do not appear to play a significant role in defining amyloid propensity. Based on the structural and biophysical data, our results highlight shared properties driving LC amyloid propensity, and these data will be instrumental for the design of synthetic inhibitors of LC aggregation. PMID- 29196672 TI - Network Properties in Transitions of Consciousness during Propofol-induced Sedation. AB - Reliable electroencephalography (EEG) signatures of transitions between consciousness and unconsciousness under anaesthesia have not yet been identified. Herein we examined network changes using graph theoretical analysis of high density EEG during patient-titrated propofol-induced sedation. Responsiveness was used as a surrogate for consciousness. We divided the data into five states: baseline, transition into unresponsiveness, unresponsiveness, transition into responsiveness, and recovery. Power spectral analysis showed that delta power increased from responsiveness to unresponsiveness. In unresponsiveness, delta waves propagated from frontal to parietal regions as a traveling wave. Local increases in delta connectivity were evident in parietal but not frontal regions. Graph theory analysis showed that increased local efficiency could differentiate the levels of responsiveness. Interestingly, during transitions of responsive states, increased beta connectivity was noted relative to consciousness and unconsciousness, again with increased local efficiency. Abrupt network changes are evident in the transitions in responsiveness, with increased beta band power/connectivity marking transitions between responsive states, while the delta power/connectivity changes were consistent with the fading of consciousness using its surrogate responsiveness. These results provide novel insights into the neural correlates of these behavioural transitions and EEG signatures for monitoring the levels of consciousness under sedation. PMID- 29196673 TI - Proton gradients and pH oscillations emerge from heat flow at the microscale. AB - Proton gradients are essential for biological systems. They not only drive the synthesis of ATP, but initiate molecule degradation and recycling inside lysosomes. However, the high mobility and permeability of protons through membranes make pH gradients very hard to sustain in vitro. Here we report that heat flow across a water-filled chamber forms and sustains stable pH gradients. Charged molecules accumulate by convection and thermophoresis better than uncharged species. In a dissociation reaction, this imbalances the reaction equilibrium and creates a difference in pH. In solutions of amino acids, phosphate, or nucleotides, we achieve pH differences of up to 2 pH units. The same mechanism cycles biomolecules by convection in the created proton gradient. This implements a feedback between biomolecules and a cyclic variation of the pH. The finding provides a mechanism to create a self-sustained proton gradient to drive biochemical reactions. PMID- 29196674 TI - Artificial controlled model of blood circulation system for adhesive evaluation. AB - Since there are several casualties due to uncontrolled bleeding resulting from simple injury to surgery, effective styptic or vessel adhesives are important; however, their development is limited by the lack of standardized systems to evaluate potential compounds. The current study outlines the development of an aorta styptic evaluation system, comprising of decellularized swine aorta tissue and a heart pump-mimicking system. Although the cells in the swine aorta were removed, the structural stability of the aorta was sustained due to the maintenance of the extracellular matrix. Using a control adhesive, Cyanoacrylate, the developed model was found to have similar adhesive efficacy to intact aorta. The circulatory-mimicking system was designed to mimic the beat rate and strength of blood-flow from the heart, which was necessary to evaluate the adherent efficacy. The decellularized aorta improves instabilities of intact tissues, which occurs on account of storage and origin, thereby allowing for a more standardized system. The system was able to simulate several symptoms of circulation, according to patient age and health, by adjusting pumping frequency and intensity. Therefore, this system can be used as a standardized evaluation system for screening adhesives. Further, it would also evaluate other medical devices, such as stent or medications. PMID- 29196675 TI - Low temperature and low salinity drive putatively adaptive growth differences in populations of threespine stickleback. AB - Colonisation can expose organisms to novel combinations of abiotic and biotic factors and drive adaptive divergence. Yet, studies investigating the interactive effects of multiple abiotic factors on the evolution of physiological traits remain rare. Here we examine the effects of low salinity, low temperature, and their interaction on the growth of three North American populations of threespine stickleback (Gasterosteus aculeatus). In north-temperate freshwater habitats, stickleback populations experience a combination of low salinity and low winter temperatures that are not experienced by the ancestral marine and anadromous populations. Here we show that both salinity and temperature, and their interaction, have stronger negative effects on marine and anadromous populations than a freshwater population. Freshwater stickleback showed only a ~20% reduction in specific growth rate when exposed to 4 degrees C, while marine and anadromous stickleback showed sharp declines (82% and 74% respectively) under these conditions. The modest decreases in growth in freshwater stickleback in fresh water in the cold strongly suggest that this population has the capacity for physiological compensation to offset the negative thermodynamic effects of low temperature on growth. These results are suggestive of adaptive evolution in response to the interactive effects of low salinity and low temperature during freshwater colonisation. PMID- 29196676 TI - Efficiency of novel nanocombinations of bovine milk proteins (lactoperoxidase and lactoferrin) for combating different human cancer cell lines. AB - Bovine lactoperoxidase (LPO) and lactoferrin (LF) are suitable proteins to be loaded or adsorbed to chitosan nanoparticles (NPs) for preparing stable nanoformulations with potent anticancer activity. In the present study, nanocombinations of LPO and LF revealed improvement in their stability and activity compared to single (free or nanoformulated) bovine proteins. The coating or loading of LPO-loaded NPs with LF resulted in the highest synergistic cytotoxicity effect against Caco-2, HepG-2, MCF-7 and PC-3 cells in comparison with other NPs and free proteins without causing toxicity toward normal cells. This synergistic improvement in the anticancer activity was apoptosis-dependent that was confirmed by severe alterations in cellular morphology, high percentage of annexin-stained cells and sub-G1 populations as well as nuclear staining with orange fluorescence of treated cancer cells. Additionally, significant alterations in the expression of well characterized cellular proliferation and apoptosis guards (NF-kappaB, Bcl-2 and p53) in these NPs-treated cancer cells compared to 5-fluorouracil (5-FU) treated cells. Our findings provide for the first time that these new synergistic nanoformulated forms of LPO and LF were superior in their selective apoptosis-mediating anticancer effect than free form of these proteins and 5-FU. LF coating or loading of LPO-loaded NPs present as promising therapy for cancer. PMID- 29196677 TI - Enhancement and suppression of turbulence by energetic-particle-driven geodesic acoustic modes. AB - We propose a novel mechanism of enhancement of turbulence by energetic-particle driven geodesic acoustic modes (EGAMs). The dynamics of drift-wave-type turbulence in the phase space is investigated by wave-kinetic equation. Spatially inhomogeneous turbulence in the presence of a transport barrier is considered. We discovered that trapping of turbulence clumps by the EGAMs is the key parameter that determines either suppress or enhance turbulence. In regions where turbulence is unstable, EGAM suppresses the turbulence. In contrast, in the stable region, EGAM traps clumps of turbulence and carries them across the transport barrier, so that the turbulence can be enhanced. The turbulence trapped by EGAMs can propagate independent of the gradients of density and temperature, which leads to non-Fickian transport. Hence, there appear a new global characteristic velocity, the phase velocity of GAMs, for turbulence dynamics, in addition to the local group velocity and that of the turbulence spreading. With these effect, EGAMs can deteriorate transport barriers and affect turbulence substantially. This manuscript provides a basis to consider whether a coherent wave breaks or strengthen transport barriers.

AB - Reconstructing phylogeny from retrotransposon insertions is often limited by access to only a single reference genome, whereby support for clades that do not include the reference taxon cannot be directly observed. Here we have developed a new statistical framework that accounts for this ascertainment bias, allowing us to employ phylogenetically powerful retrotransposon markers to explore the radiation of the largest living marsupials, the kangaroos and wallabies of the genera Macropus and Wallabia. An exhaustive in silico screening of the tammar wallaby (Macropus eugenii) reference genome followed by experimental screening revealed 29 phylogenetically informative retrotransposon markers belonging to a family of endogenous retroviruses. We identified robust support for the enigmatic swamp wallaby (Wallabia bicolor) falling within a paraphyletic genus, Macropus. Our statistical approach provides a means to test for incomplete lineage sorting and introgression/hybridization in the presence of the ascertainment bias. Using retrotransposons as "molecular fossils", we reveal one of the most complex patterns of hemiplasy yet identified, during the rapid diversification of kangaroos and wallabies. Ancestral state reconstruction incorporating the new retrotransposon phylogenetic information reveals multiple independent ecological shifts among kangaroos into more open habitats, coinciding with the Pliocene onset of increased aridification in Australia from ~3.6 million years ago.

AB - Agent-based modelling is a useful approach for capturing heterogeneity in disease transmission. In this study, a synthetic population was developed for American Samoa using an iterative approach based on population census, questionnaire survey and land use data. The population will be used as the basis for a new agent-based model, intended specifically to fill the knowledge gaps about lymphatic filariasis transmission and elimination, but also to be readily adaptable to model other infectious diseases. The synthetic population was characterized by the statistically realistic population and household structure, and high-resolution geographic locations of households. The population was simulated over 40 years from 2010 to 2050. The simulated population was compared to estimates and projections of the U.S. Census Bureau. The results showed the total population would continuously decrease due to the observed large number of emigrants. Population ageing was observed, which was consistent with the latest two population censuses and the Bureau's projections. The sex ratios by age groups were analysed and indicated an increase in the proportion of males in age groups 0-14 and 15-64. The household size followed a Gaussian distribution with an average size of around 5.0 throughout the simulation, slightly less than the initial average size 5.6.

AB - Agrosilvopastoral and silvopastoral systems can increase carbon sequestration, offset greenhouse gas (GHG) emissions and reduce the carbon footprint generated by animal production. The objective of this study was to estimate GHG emissions, the tree and grass aboveground biomass production and carbon storage in different agrosilvopastoral and silvopastoral systems in southeastern Brazil. The number of trees required to offset these emissions were also estimated. The GHG emissions were calculated based on pre-farm (e.g. agrochemical production, storage, and transportation), and on-farm activities (e.g. fertilization and machinery operation). Aboveground tree grass biomass and carbon storage in all systems was estimated with allometric equations. GHG emissions from the agroforestry systems ranged from 2.81 to 7.98 t CO2e ha-1. Carbon storage in the aboveground trees and grass biomass were 54.6, 11.4, 25.7 and 5.9 t C ha-1, and 3.3, 3.6, 3.8 and 3.3 t C ha-1 for systems 1, 2, 3 and 4, respectively. The number of trees necessary to offset the emissions ranged from 17 to 44 trees ha-1, which was lower than the total planted in the systems. Agroforestry systems sequester CO2 from the atmosphere and can help the GHG emission-reduction policy of the Brazilian government.

AB - Seeking nuclear materials that possess a high resistance to particle irradiation damage is a long-standing issue. Permanent defects, induced by irradiation, are primary structural changes, the accumulation of which will lead to structural damage and performance degradation in crystalline materials served in nuclear plants. In this work, structural responses of neutron irradiation in metallic glasses (MGs) have been investigated by making a series of experimental measurements, coupled with simulations in ZrCu amorphous alloys. It is found that, compared with crystalline alloys, MGs have some specific structural responses to neutron irradiation. Although neutron irradiation can induce transient vacancy-like defects in MGs, they are fully annihilated after structural relaxation by rearrangement of free volumes. In addition, the rearrangement of free volumes depends strongly on constituent elements. In particular, the change in free volumes occurs around the Zr atoms, rather than the Cu centers. This implies that there is a feasible strategy for identifying glassy materials with high structural stability against neutron irradiation by tailoring the microstructures, the systems, or the compositions in alloys. This work will shed light on the development of materials with high irradiation resistance. PMID- 29196682 TI - On the proportional abundance of species: Integrating population genetics and community ecology. AB - The frequency of genes in interconnected populations and of species in interconnected communities are affected by similar processes, such as birth, death and immigration. The equilibrium distribution of gene frequencies in structured populations is known since the 1930s, under Wright's metapopulation model known as the island model. The equivalent distribution for the species frequency (i.e. the species proportional abundance distribution (SPAD)), at the metacommunity level, however, is unknown. In this contribution, we develop a stochastic model to analytically account for this distribution (SPAD). We show that the same as for genes SPAD follows a beta distribution, which provides a good description of empirical data and applies across a continuum of scales. This stochastic model, based upon a diffusion approximation, provides an alternative to neutral models for the species abundance distribution (SAD), which focus on number of individuals instead of proportions, and demonstrate that the relative frequency of genes in local populations and of species within communities follow the same probability law. We hope our contribution will help stimulate the mathematical and conceptual integration of theories in genetics and ecology. PMID- 29196683 TI - Preferential selection of Arginine at the lipid-water-interface of TRPV1 during vertebrate evolution correlates with its snorkeling behaviour and cholesterol interaction. AB - TRPV1 is a thermo-sensitive ion channel involved in neurosensory and other physiological functions. The trans-membrane helices of TRPV1 undergo quick and complex conformational changes governed by thermodynamic parameters and membrane components leading to channel opening. However, the molecular mechanisms underlying such events are poorly understood. Here we analysed the molecular evolution of TRPV1 at the lipid-water-interface region (LWI), typically defined as a layer of 6 A thickness on each side of the membrane with less availability of free water. Amino acids demarcating the end of the trans-membrane helices are highly conserved. Residues present in the inner leaflet are more conserved and have been preferentially selected over others. Amino acids with snorkeling properties (Arginine and Tyrosine) undergo specific selection during the vertebrate evolution in a cholesterol-dependent and/or body temperature manner. Results suggest that H-bond formation between the OH- group of cholesterol and side chain of Arg557 or Arg575 at the inner leaflet is a critical parameter that can regulate channel functions. Different LWI mutants of TRPV1 have altered membrane localization and deficient colocalization with lipid raft markers. These findings may help to understand the lipid-protein interactions, and molecular basis of different neuronal functions. Such findings may have broad importance in the context of differential sensory responses, pathophysiologies, and application of pharmacological drugs such as anaesthetics acting on TRPVs. PMID- 29196684 TI - Squalene epoxidase plays a critical role in determining pig meat quality by regulating adipogenesis, myogenesis, and ROS scavengers. AB - In mammals, Squalene epoxidase (SQLE) is an enzyme that converts squalene to 2,3 oxidosqualene, in the early stage of cholesterol generation. Here, we identified single nucleotide polymorphisms (SNPs) in the SQLE gene (c.2565 G > T) by RNA Sequencing from the liver tissue of Berkshire pigs. Furthermore, we found that homozygous GG pigs expressed more SQLE mRNA than GT heterozygous and TT homozygous pigs in longissimus dorsi tissue. Next, we showed that the SNP in the SQLE gene was associated with several meat quality traits including backfat thickness, carcass weight, meat colour (yellowness), fat composition, and water holding capacity. Rates of myogenesis and adipogenesis induced in C2C12 cells and 3T3-L1 cells, respectively, were decreased by Sqle knockdown. Additionally, the expression of myogenic marker genes (Myog, Myod, and Myh4) and adipogenic marker genes (Pparg, Cebpa, and Adipoq) was substantially downregulated in cells transfected with Sqle siRNA. Moreover, mRNA expression levels of ROS scavengers, which affect meat quality by altering protein oxidation processes, were significantly downregulated by Sqle knockdown. Taken together, our results suggest the molecular mechanism by which SNPs in the SQLE gene can affect meat quality. PMID- 29196685 TI - Medical examination powers miR-194-5p as a biomarker for postmenopausal osteoporosis. AB - An important attribute of microRNAs is their potential use as disease biomarkers. However, such applications may be restricted because of unsatisfactory performance of the microRNA of interest. Owing to moderate correlation with spine T-score, miR-194-5p was identified as a potential biomarker for postmenopausal osteoporosis. Here, we determined whether medical examination could improve its characteristic as a biomarker for postmenopausal osteoporosis. We recruited 230 postmenopausal Chinese women to measure circulating levels of miR-194-5p, determine the spine bone status, and perform a 42-item medical examination. No obvious information redundancy was observed between miR-194-5p and any one item. However, on examining miR-194-5p alone, the sensitivity at fixed specificity of 0.9 (SESP=0.9) was 0.27, implying poor identification of at-risk individuals. Model integration of the microRNA and multiple medical items strengthened this property; in addition, model complexity greatly contributed to performance improvement. Using a model composed of two artificial neural networks, the ability of miR-194-5p to identify at-risk individuals significantly improved (SESP=0.9 = 0.54) when correlated with five medical items: weight, age, left ventricular end systolic diameter, alanine aminotransferase, and urine epithelial cell count. We present a feasible way to achieve a more accurate microRNA-based biomarker for a disease of interest. PMID- 29196686 TI - Resting-state functional MRI reveals altered brain connectivity and its correlation with motor dysfunction in a mouse model of Huntington's disease. AB - Huntington's disease (HD) is an autosomal dominant inherited neurodegenerative disorder, and no cure is available currently. Treatment of HD is likely to be most beneficial in the early, possibly pre-manifestation stage. The challenge is to determine the best time for intervention and evaluate putative efficacy in the absence of clinical symptoms. Resting-state functional MRI may represent a promising tool to develop biomarker reflecting early neuronal dysfunction in HD brain, because it can examine multiple brain networks without confounding effects of cognitive ability, which makes the resting-state fMRI promising as a translational bridge between preclinical study in animal models and clinical findings in HD patients. In this study, we examined brain regional connectivity and its correlation to brain atrophy, as well as motor function in the 18-week old N171-82Q HD mice. HD mice exhibited significantly altered functional connectivity in multiple networks. Particularly, the weaker intra-striatum connectivity was positively correlated with striatal atrophy, while striatum retrosplenial cortex connectivity is negatively correlated with striatal atrophy. The resting-state brain regional connectivity had no significant correlation with motor deficits in HD mice. Our results suggest that altered brain connectivity detected by resting-state fMRI might serve as an early disease biomarker in HD. PMID- 29196687 TI - 2.8 MUm emission and OH quenching analysis in Ho3+ doped fluorotellurite germanate glasses sensitized by Yb3+ and Er3. AB - The use of Yb3+ and Er3+ co-doping with Ho3+ to enhance and broaden the Ho3+: 5I6 -> 5I7 ~2.8 MUm emissions are investigated in the fluorotellurite-germanate glasses. An intense ~3 MUm emission with a full width at half maximum (FWHM) of 245 nm is achieved in the Er3+/Ho3+/Yb3+ triply-doped fluorotellurite-germanate glass upon excitation at 980 nm. The glass not only possesses considerably low OH absorption coefficient (0.189 cm-1), but also exhibits low phonon energy (704 cm 1). Moreover, the measured lifetime of Ho3+: 5I6 level is as high as 0.218 ms. In addition, the energy transfer rate to hydroxyl groups and quantum efficiency (eta) of 5I6 level were calculated in detail by fitting the variations of lifetimes vs. the OH- concentrations. The formation ability and thermal stability of glasses have been improved by introducing GeO2 into fluorotellurite glasses. Results reveal that Er3+/Ho3+/Yb3+ triply-doped fluorotellurite-germanate glass is a potential kind of laser glass for efficient 3 MUm laser. PMID- 29196688 TI - Investigation of Atrial Vortices Using a Novel Right Heart Model and Possible Implications for Atrial Thrombus Formation. AB - The main aim of this paper is to characterize vortical flow structures in the healthy human right atrium, their impact on wall shear stresses and possible implications for atrial thrombus formation. 3D Particle Tracking Velocimetry is applied to a novel anatomically accurate compliant silicone right heart model to study the phase averaged and fluctuating flow velocity within the right atrium, inferior vena cava and superior vena cava under physiological conditions. We identify the development of two vortex rings in the bulk of the right atrium during the atrial filling phase leading to a rinsing effect at the atrial wall which break down during ventricular filling. We show that the vortex ring formation affects the hemodynamics of the atrial flow by a strong correlation (rho = 0.7) between the vortical structures and local wall shear stresses. Low wall shear stress regions are associated with absence of the coherent vortical structures which might be potential risk regions for atrial thrombus formation. We discuss possible implications for atrial thrombus formation in different regions of the right atrium. PMID- 29196689 TI - Impact of the crystal orientation of Fe-doped lithium niobate on photo-assisted proton exchange and chemical etching. AB - Photo-assisted proton-exchange (PAPE) is carried out on the +c- and y-surfaces of Fe-doped LiNbO3 crystals and the impact of the crystal orientation on the PAPE and the subsequent photo-assisted chemical etching (PACE) is investigated. The proton distributions and the morphologies of the proton-exchanged surfaces are studied by using Micro-FT-IR, Micro-Raman, optical and scanning electron microscopy. Through the PAPE process the proton-exchange can be confined in a specific region by an incident laser beam with fixed intensity profile. It is found that the y-surface is much more fragile than the +c-surface and that micro cracks are easily generated on the y-surface during the PAPE process. Moreover, the range and number of these micro-cracks can be controlled by the experimental parameters of the PAPE process. The etching morphology of the y-surface shows apparent directional features along the c-axis of LiNbO3 crystal and the proton spatial distribution is found elongated along the c-axis. Both effects are attributed to the accumulation of photovoltaic charges at the two sides of the illumination area along the c-axis. PMID- 29196690 TI - Fano resonances in bilayer graphene superlattices. AB - In this work, we address the ubiquitous phenomenon of Fano resonances in bilayer graphene. We consider that this phenomenon is as exotic as other phenomena in graphene because it can arise without an external extended states source or elaborate nano designs. However, there are not theoretical and/or experimental studies that report the impact of Fano resonances on the transport properties. Here, we carry out a systematic assessment of the contribution of the Fano resonances on the transport properties of bilayer graphene superlattices. Specifically, we find that by changing the number of periods, adjusting the barriers height as well as modifying the barriers and wells width it is possible to identify the contribution of Fano resonances on the conductance. Particularly, the coupling of Fano resonances with the intrinsic minibands of the superlattice gives rise to specific and identifiable changes in the conductance. Moreover, by reducing the angular range for the computation of the transport properties it is possible to obtain conductance curves with line-shapes quite similar to the Fano profile and the coupling profile between Fano resonance and miniband states. In fact, these conductance features could serve as unequivocal characteristic of the existence of Fano resonances in bilayer graphene. PMID- 29196692 TI - Advancement of magma fragmentation by inhomogeneous bubble distribution. AB - Decompression times reported in previous studies suggest that thoroughly brittle fragmentation is unlikely in actual explosive volcanic eruptions. What occurs in practice is brittle-like fragmentation, which is defined as the solid-like fracture of a material whose bulk rheological properties are close to those of a fluid. Through laboratory experiments and numerical simulation, the link between the inhomogeneous structure of bubbles and the development of cracks that may lead to brittle-like fragmentation was clearly demonstrated here. A rapid decompression test was conducted to simulate the fragmentation of a specimen whose pore morphology was revealed by X-ray microtomography. The dynamic response during decompression was observed by high-speed photography. Large variation was observed in the responses of the specimens even among specimens with equal bulk rheological properties. The stress fields of the specimens under decompression computed by finite element analysis shows that the presence of satellite bubbles beneath a large bubble induced the stress concentration. On the basis of the obtained results, a new mechanism for brittle-like fragmentation is proposed. In the proposed scenario, the second nucleation of bubbles near the fragmentation surface is an essential process for the advancement of fragmentation in an upward magma flow in a volcanic conduit. PMID- 29196691 TI - Evidence for single metal two electron oxidative addition and reductive elimination at uranium. AB - Reversible single-metal two-electron oxidative addition and reductive elimination are common fundamental reactions for transition metals that underpin major catalytic transformations. However, these reactions have never been observed together in the f-block because these metals exhibit irreversible one- or multi electron oxidation or reduction reactions. Here we report that azobenzene oxidises sterically and electronically unsaturated uranium(III) complexes to afford a uranium(V)-imido complex in a reaction that satisfies all criteria of a single-metal two-electron oxidative addition. Thermolysis of this complex promotes extrusion of azobenzene, where H-/D-isotopic labelling finds no isotopomer cross-over and the non-reactivity of a nitrene-trap suggests that nitrenes are not generated and thus a reductive elimination has occurred. Though not optimally balanced in this case, this work presents evidence that classical d block redox chemistry can be performed reversibly by f-block metals, and that uranium can thus mimic elementary transition metal reactivity, which may lead to the discovery of new f-block catalysis. PMID- 29196693 TI - Relationship between erectile dysfunction and the neutrophil to lymphocyte and platelet to lymphocyte ratios. AB - The most important cause of erectile dysfunction (ED) among aging men is organic disease due to vascular disturbance that is often caused by atherosclerosis. Recently, studies have shown that atherosclerosis can manifest as an active inflammatory process rather than as passive vascular injury caused by lipid infiltration. Our study aimed to examine the association of ED with the neutrophil/lymphocyte ratio (NLR) and the platelet/lymphocyte ratio (PLR), both of which are markers of inflammation. Between December 2014 and May 2015, 101 male patients aged 40-70 years who were seen at our institute due to ED were included in this study. Thirty-one sexually active men with similar clinical and demographic characteristics without ED were included in our study as a control group. The control and patient groups were compared with respect to their NLR and PLR values as well as other hormonal, biochemical, hematological parameters. The median ages of the patient and control groups were 49 (40-69) and 48 (43-65) years old, respectively. Comorbidities such as hypertension, diabetes, chronic obstructive pulmonary disease (COPD), and coronary artery disease were not significantly different between the groups (p > 0.05). The neutrophil-to lymphocyte and platelet-to-lymphocyte ratios were significantly higher in the patient group than in the control group (p < 0.05). Furthermore, the detected CRP levels were also significantly higher in the patient group than in the control group (p < 0.001). In the correlation analysis, the NLR, PLR, and CRP levels were negatively correlated with the IIEF-5 scores. A multivariate analysis was performed to determine the independent predictors of ED. PLR was identified as an independent predictor for ED. The neutrophil-to-lymphocyte and especially platelet-to-lymphocyte ratios are correlated with a diagnosis of ED, and these ratios could serve as practical parameters that will not elicit additional costs. PMID- 29196694 TI - Latent tuberculosis infection among patients with erectile dysfunction. AB - No previous studies have investigated the prevalence of latent tuberculosis infection (LTBI) among patients with erectile dysfunction (ED) or its contribution to the development of high-grade ED through a process of chronic inflammation-induced atherosclerosis. The aim of this study was to determine the frequency of LTBI among patients with erectile dysfunction and to explore the contribution of LTBI to high-grade ED. For all the study sample, clinical evaluation, imaging studies, and laboratory investigations were provided. Evaluation included, but was not confined to, scrotal ultrasonography, tuberculin skin test, and QuantiFERON-TB Gold test. The study sample mean +/- SD age was 47.9 +/- 13.6 years. Approximately 30% of the patients had LTBI and 43% had high grade ED. After a multivariate analysis, it was found that older age (>=40 years) (OR, 5.2; 95% CI, 1.9-54.6; p 0.004), metabolic syndrome (MS) (OR, 3.4; 95% CI, 1.3-48.2; p 0.016), and LTBI (OR, 4.1; 95% CI, 1.7-61.3; p 0.021) were significantly, independently associated with high-grade ED as opposed to low grade ED. In conclusion, the prevalence of LTBI among patients with high-grade ED is higher than among those with low-grade ED. In addition to LTBI, older age and MS are associated with high-grade ED as opposed to low-grade ED. PMID- 29196695 TI - Legume crop rotation suppressed nitrifying microbial community in a sugarcane cropping soil. AB - Nitrifying microorganisms play an important role in nitrogen (N) cycling in agricultural soils as nitrification leads to accumulation of nitrate (NO3-) that is readily lost through leaching and denitrification, particularly in high rainfall regions. Legume crop rotation in sugarcane farming systems can suppress soil pathogens and improve soil health, but its effects on soil nitrifying microorganisms are not well understood. Using shotgun metagenomic sequencing, we investigated the impact of two legume break crops, peanut (Arachis hypogaea) and soybean (Glycine max), on the nitrifying communities in a sugarcane cropping soil. Cropping with either legume substantially increased abundances of soil bacteria and archaea and altered the microbial community composition, but did not significantly alter species richness and evenness relative to a bare fallow treatment. The ammonia oxidisers were mostly archaeal rather than bacterial, and were 24-44% less abundant in the legume cropping soils compared to the bare fallow. Furthermore, abundances of the archaeal amoA gene encoding ammonia monooxygenase in the soybean and peanut cropping soils were only 30-35% of that in the bare fallow. These results warrant further investigation into the mechanisms driving responses of ammonia oxidising communities and their nitrification capacity in soil during legume cropping.

PMID- 29196697 TI - De novo transcriptome assembly of Zanthoxylum bungeanum using Illumina sequencing for evolutionary analysis and simple sequence repeat marker development. AB - Zanthoxylum, an ancient economic crop in Asia, has a satisfying aromatic taste and immense medicinal values. A lack of genomic information and genetic markers has limited the evolutionary analysis and genetic improvement of Zanthoxylum species and their close relatives. To better understand the evolution, domestication, and divergence of Zanthoxylum, we present a de novo transcriptome analysis of an elite cultivar of Z. bungeanum using Illumina sequencing; we then developed simple sequence repeat markers for identification of Zanthoxylum. In total, we predicted 45,057 unigenes and 22,212 protein coding sequences, approximately 90% of which showed significant similarities to known proteins in databases. Phylogenetic analysis indicated that Zanthoxylum is relatively recent and estimated to have diverged from Citrus ca. 36.5-37.7 million years ago. We also detected a whole-genome duplication event in Zanthoxylum that occurred 14 million years ago. We found no protein coding sequences that were significantly under positive selection by Ka/Ks. Simple sequence repeat analysis divided 31 Zanthoxylum cultivars and landraces into three major groups. This Zanthoxylum reference transcriptome provides crucial information for the evolutionary study of the Zanthoxylum genus and the Rutaceae family, and facilitates the establishment of more effective Zanthoxylum breeding programs. PMID- 29196698 TI - High-pressure versus low-pressure home non-invasive positive pressure ventilation with built-in software in patients with stable hypercapnic COPD: a pilot study. AB - High-pressure non-invasive positive pressure ventilation (NPPV) is a new strategy targeted at maximally reducing arterial carbon dioxide. However, high inspiratory positive airway pressure (IPAP) might cause respiratory adverse events likely to diminish the benefit of NPPV. In the setting of ventilatory support, monitoring NPPV efficacy and resolving problems promptly are critical. This study assessed the treatment effect of high and low-pressure NPPV in chronic hypercapnic COPD using home ventilator with built-in software. In this pilot study, we investigated 34 patients using NPPV for 3 months. 13 patients used high-pressure ventilation and 21 patients used low-pressure ventilation. The primary outcome was daytime partial pressure of arterial blood carbon dioxide (PaCO2). There were no between-group differences in daytime PaCO2 and FEV1, but a trend favouring high-pressure NPPV was observed. Significant between-group differences were found in the transition dyspnoea index (TDI) (high-pressure, 1.69 +/- 1.75, versus low pressure, -0.04 +/- 2.71, p = 0.044). No differences were found in usage time, leakage, health-related quality of life, spirometry, or 6-minute walk test. High pressure NPPV with built-in software monitoring in patients with chronic hypercapnic COPD is associated with improvement in TDI scores and a positive trend in favour of high-pressure NPPV for improving PaCO2 is observed. PMID- 29196700 TI - Thermally nucleated magnetic reversal in CoFeB/MgO nanodots. AB - Power consumption is the main limitation in the development of new high performance random access memory for portable electronic devices. Magnetic RAM (MRAM) with CoFeB/MgO based magnetic tunnel junctions (MTJs) is a promising candidate for reducing the power consumption given its non-volatile nature while achieving high performance. The dynamic properties and switching mechanisms of MTJs are critical to understanding device operation and to enable scaling of devices below 30 nm in diameter. Here we show that the magnetic reversal mechanism is incoherent and that the switching is thermally nucleated at device operating temperatures. Moreover, we find an intrinsic thermal switching field distribution arising on the sub-nanosecond time-scale even in the absence of size and anisotropy distributions or material defects. These features represent the characteristic signature of the dynamic properties in MTJs and give an intrinsic limit to reversal reliability in small magnetic nanodevices. PMID- 29196699 TI - Altered resting-state brain activity in Parkinson's disease patients with freezing of gait. AB - Freezing of gait (FOG) is a common and debilitating symptom in Parkinson's disease (PD). The current study investigated alterations of resting-state spontaneous brain activity in PD patients with FOG. A total of 29 patients with FOG, 28 patients without FOG and 31 controls were included. All subjects underwent resting-state functional MRI, and the amplitude of low-frequency fluctuation (ALFF) was calculated to measure the spontaneous brain activity. Between-group differences and correlations with FOG severity (both subjective and objective measures) were analyzed. Compared to those without FOG, patients with FOG showed increased ALFF in right anterior cingulate cortex (ACC) and left inferior parietal lobule (IPL), as well as decreased ALFF in right superior frontal gyrus (SFG), bilateral cerebellum and left thalamus. Correlation analyses demonstrated that ALFF within the right SFG, right ACC and bilateral pallidum were positively correlated with FOG; while ALFF within the thalamus, putamen, cerebellum and sensorimotor regions were negatively correlated. Our results indicate that FOG is associated with dysfunction within frontal-parietal regions, along with increased inhibitory outputs from basal ganglia. Additionally, altered activity of cerebellum implicates its role in the pathophysiology of FOG. These findings provide further insight into the underlying neural mechanisms of FOG in PD patients. PMID- 29196701 TI - The repeat region of cortactin is intrinsically disordered in solution. AB - The multi-domain protein, cortactin, contains a 37-residue repeating motif that binds to actin filaments. This cortactin repeat region comprises 61/2 similar copies of the motif and binds actin filaments. To better understand this region of cortactin, and its fold, we conducted extensive biophysical analysis. Size exclusion chromatography with multi-angle light scattering (SEC-MALS) reveals that neither constructs of the cortactin repeats alone or together with the adjacent helical region homo-oligomerize. Using circular dichroism (CD) we find that in solution the cortactin repeats resemble a coil-like intrinsically disordered protein. Small-angle X-ray scattering (SAXS) also indicates that the cortactin repeats are intrinsically unfolded, and the experimentally observed radius of gyration (R g) is coincidental to that calculated by the program Flexible-Meccano for an unfolded peptide of this length. Finally, hydrogen deuterium exchange mass spectrometry (HDX-MS) indicates that the domain contains limited hydrophobic core regions. These experiments therefore provide evidence that in solution the cortactin repeat region of cortactin is intrinsically disordered. PMID- 29196702 TI - Spatial statistical modelling of capillary non-perfusion in the retina. AB - Manual grading of lesions in retinal images is relevant to clinical management and clinical trials, but it is time-consuming and expensive. Furthermore, it collects only limited information - such as lesion size or frequency. The spatial distribution of lesions is ignored, even though it may contribute to the overall clinical assessment of disease severity, and correspond to microvascular and physiological topography. Capillary non-perfusion (CNP) lesions are central to the pathogenesis of major causes of vision loss. Here we propose a novel method to analyse CNP using spatial statistical modelling. This quantifies the percentage of CNP-pixels in each of 48 sectors and then characterises the spatial distribution with goniometric functions. We applied our spatial approach to a set of images from patients with malarial retinopathy, and found it compares favourably with the raw percentage of CNP-pixels and also with manual grading. Furthermore, we were able to quantify a biological characteristic of macular CNP in malaria that had previously only been described subjectively: clustering at the temporal raphe. Microvascular location is likely to be biologically relevant to many diseases, and so our spatial approach may be applicable to a diverse range of pathological features in the retina and other organs.

AB - Chitosan is a natural polymer with applications in agriculture, which causes plasma membrane permeabilisation and induction of intracellular reactive oxygen species (ROS) in plants. Chitosan has been mostly applied in the phylloplane to control plant diseases and to enhance plant defences, but has also been considered for controlling root pests. However, the effect of chitosan on roots is virtually unknown. In this work, we show that chitosan interfered with auxin homeostasis in Arabidopsis roots, promoting a 2-3 fold accumulation of indole acetic acid (IAA). We observed chitosan dose-dependent alterations of auxin synthesis, transport and signalling in Arabidopsis roots. As a consequence, high doses of chitosan reduce WOX5 expression in the root apical meristem and arrest root growth. Chitosan also propitiates accumulation of salicylic (SA) and jasmonic (JA) acids in Arabidopsis roots by induction of genes involved in their biosynthesis and signalling. In addition, high-dose chitosan irrigation of tomato and barley plants also arrests root development. Tomato root apices treated with chitosan showed isodiametric cells respect to rectangular cells in the controls. We found that chitosan causes strong alterations in root cell morphology. Our results highlight the importance of considering chitosan dose during agronomical applications to the rhizosphere.

AB - Techniques such as Stochastic Optical Reconstruction Microscopy (STORM) and Structured Illumination Microscopy (SIM) have increased the achievable resolution of optical imaging, but few fluorescent proteins are suitable for super resolution microscopy, particularly in the far-red and near-infrared emission range. Here we demonstrate the applicability of CpcA, a subunit of the photosynthetic antenna complex in cyanobacteria, for STORM and SIM imaging. The periodicity and width of fabricated nanoarrays of CpcA, with a covalently attached phycoerythrobilin (PEB) or phycocyanobilin (PCB) chromophore, matched the lines in reconstructed STORM images. SIM and STORM reconstructions of Escherichia coli cells harbouring CpcA-labelled cytochrome bd 1 ubiquinol oxidase in the cytoplasmic membrane show that CpcA-PEB and CpcA-PCB are suitable for super-resolution imaging in vivo. The stability, ease of production, small size and brightness of CpcA-PEB and CpcA-PCB demonstrate the potential of this largely unexplored protein family as novel probes for super-resolution microscopy. PMID- 29196705 TI - Energetic instability of passive states in thermodynamics. AB - Passivity is a fundamental concept in thermodynamics that demands a quantum system's energy cannot be lowered by any reversible, unitary process acting on the system. In the limit of many such systems, passivity leads in turn to the concept of complete passivity, thermal states and the emergence of a thermodynamic temperature. Here we only consider a single system and show that every passive state except the thermal state is unstable under a weaker form of reversibility. Indeed, we show that given a single copy of any athermal quantum state, an optimal amount of energy can be extracted from it when we utilise a machine that operates in a reversible cycle. This means that for individual systems, the only form of passivity that is stable under general reversible processes is complete passivity, and thus provides a physically motivated identification of thermal states when we are not operating in the thermodynamic limit. PMID- 29196706 TI - MALDI mass spectrometry imaging of erlotinib administered in combination with bevacizumab in xenograft mice bearing B901L, EGFR-mutated NSCLC cells. AB - Combination therapy of erlotinib plus bevacizumab improves progression-free survival of patients with epidermal growth factor receptor-mutated (EGFR-mutated) advanced non-small-cell lung cancer (NSCLC) compared with erlotinib alone. Although improved delivery and distribution of erlotinib to tumours as a result of the normalization of microvessels by bevacizumab is thought to be one of the underlying mechanisms, there is insufficient supporting evidence. B901L cells derived from EGFR-mutated NSCLC were subcutaneously implanted into mice, and mice were treated with bevacizumab or human IgG followed by treatment with erlotinib. The distribution of erlotinib in their tumours at different times after erlotinib administration was analysed by matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI MSI). We also analysed the distribution of erlotinib metabolites and the distribution of erlotinib in tumours refractory to erlotinib, which were established by long-term treatment with erlotinib. We found that erlotinib was broadly diffused in the tumours from B901L-implanted xenograft mice, independently of bevacizumab treatment. We also found that erlotinib metabolites were co-localized with erlotinib and that erlotinib in erlotinib refractory tumours was broadly distributed throughout the tumour tissue. Multivariate imaging approaches using MALDI MSI as applied in this study are of great value for pharmacokinetic studies in drug development. PMID- 29196707 TI - Crumbs, Moesin and Yurt regulate junctional stability and dynamics for a proper morphogenesis of the Drosophila pupal wing epithelium. AB - The Crumbs (Crb) complex is a key epithelial determinant. To understand its role in morphogenesis, we examined its function in the Drosophila pupal wing, an epithelium undergoing hexagonal packing and formation of planar-oriented hairs. Crb distribution is dynamic, being stabilized to the subapical region just before hair formation. Lack of crb or stardust, but not DPatj, affects hexagonal packing and delays hair formation, without impairing epithelial polarities but with increased fluctuations in cell junctions and perimeter length, fragmentation of adherens junctions and the actomyosin cytoskeleton. Crb interacts with Moesin and Yurt, FERM proteins regulating the actomyosin network. We found that Moesin and Yurt distribution at the subapical region depends on Crb. In contrast to previous reports, yurt, but not moesin, mutants phenocopy crb junctional defects. Moreover, while unaffected in crb mutants, cell perimeter increases in yurt mutant cells and decreases in the absence of moesin function. Our data suggest that Crb coordinates proper hexagonal packing and hair formation, by modulating junction integrity via Yurt and stabilizing cell perimeter via both Yurt and Moesin. The Drosophila pupal wing thus appears as a useful system to investigate the functional diversification of the Crb complex during morphogenesis, independently of its role in polarity. PMID- 29196708 TI - The serine proteinase hepsin is an activator of pro-matrix metalloproteinases: molecular mechanisms and implications for extracellular matrix turnover. AB - Increasing evidence implicates serine proteinases in the proteolytic cascades leading to the pathological destruction of extracellular matrices such as cartilage in osteoarthritis (OA). We have previously demonstrated that the type II transmembrane serine proteinase (TTSP) matriptase acts as a novel initiator of cartilage destruction via the induction and activation of matrix metalloproteinases (MMPs). Hepsin is another TTSP expressed in OA cartilage such that we hypothesized this proteinase may also contribute to matrix turnover. Herein, we demonstrate that addition of hepsin to OA cartilage in explant culture induced significant collagen and aggrecan release and activated proMMP-1 and proMMP-3. Furthermore, hepsin directly cleaved the aggrecan core protein at a novel cleavage site within the interglobular domain. Hepsin expression correlated with synovitis as well as tumour necrosis factor alpha expression, and was induced in cartilage by a pro-inflammatory stimulus. However, a major difference compared to matriptase was that hepsin demonstrated markedly reduced capacity to activate proteinase-activated receptor-2. Overall, our data suggest that hepsin, like matriptase, induces potent destruction of the extracellular matrix whilst displaying distinct efficiencies for the cleavage of specific substrates. PMID- 29196709 TI - Lck is a relevant target in chronic lymphocytic leukaemia cells whose expression variance is unrelated to disease outcome. AB - Pathogenesis of chronic lymphocytic leukaemia (CLL) is contingent upon antigen receptor (BCR) expressed by malignant cells of this disease. Studies on somatic hypermutation of the antigen binding region, receptor expression levels and signal capacity have all linked BCR on CLL cells to disease prognosis. Our previous work showed that the src-family kinase Lck is a targetable mediator of BCR signalling in CLL cells, and that variance in Lck expression associated with ability of BCR to induce signal upon engagement. This latter finding makes Lck similar to ZAP70, another T-cell kinase whose aberrant expression in CLL cells also associates with BCR signalling capacity, but also different because ZAP70 is not easily pharmacologically targetable. Here we describe a robust method of measuring Lck expression in CLL cells using flow cytometry. However, unlike ZAP70 whose expression in CLL cells predicts prognosis, we find Lck expression and disease outcome in CLL are unrelated despite observations that its inhibition produces effects that biologically resemble the egress phenotype taken on by CLL cells treated with idelalisib. Taken together, our findings provide insight into the pathobiology of CLL to suggest a more complex relationship between expression of molecules within the BCR signalling pathway and disease outcome. PMID- 29196710 TI - Molecular Identification of ten species of stored-product psocids through microarray method based on ITS2 rDNA. AB - Stored-product psocids (Psocoptera: Liposcelididae) are cosmopolitan storage pests that can damage stored products and cause serious economic loss. However, because of the body size (~1 mm) of eggs, nymphs, and adults, morphological identification of most stored-product psocids is difficult and hampers effective identification. In this study, 10 economically important stored-product Liposcelis spp. psocids (Liposcelis brunnea, L. entomophila, L. decolor, L. pearmani, L. rufa, L.mendax, L. bostrychophila, L. corrodens, L. paeta, and L. tricolor) were collected from 25 geographic locations in 3 countries (China, Czech Republic, and the United States). Ten species-specific probes for identifying these 10 psocid species were designed based on ITS2 sequences. The microarray method and reaction system were optimized. Specificity of each of the ten probes was tested, and all probes were found suitable for use in identification of the respective10 Liposcelis spp. psocids at 66 degrees C. This method was also used to identify an unknown psocid species collected in Taian, China. This work has contributed to the development of a molecular identification method for stored-product psocids, and can provide technical support not only to facilitate identification of intercepted samples in relation to plant quarantine, but also for use in insect pest monitoring. PMID- 29196711 TI - The Uniform Pattern of Growth and Skeletal Maturation during the Human Adolescent Growth Spurt. AB - Humans are one of the few species undergoing an adolescent growth spurt. Because children enter the spurt at different ages making age a poor maturity measure, longitudinal studies are necessary to identify the growth patterns and identify commonalities in adolescent growth. The standard maturity determinant, peak height velocity (PHV) timing, is difficult to estimate in individuals due to diurnal, postural, and measurement variation. Using prospective longitudinal populations of healthy children from two North American populations, we compared the timing of the adolescent growth spurt's peak height velocity to normalized heights and hand skeletal maturity radiographs. We found that in healthy children, the adolescent growth spurt is standardized at 90% of final height with similar patterns for children of both sexes beginning at the initiation of the growth spurt. Once children enter the growth spurt, their growth pattern is consistent between children with peak growth at 90% of final height and skeletal maturity closely reflecting growth remaining. This ability to use 90% of final height as easily identified important maturity standard with its close relationship to skeletal maturity represents a significant advance allowing accurate prediction of future growth for individual children and accurate maturity comparisons for future studies of children's growth. PMID- 29196712 TI - Effects of neuroactive agents on axonal growth and pathfinding of retinal ganglion cells generated from human stem cells. AB - We recently established a novel method for generating functional human retinal ganglion cells (RGCs) from human induced pluripotent cells (hiPSCs). Here, we confirmed that RGCs can also be generated from human embryonic stem cells (hESCs). We investigated the usefulness of human RGCs with long axons for assessing the effects of chemical agents, such as the neurotrophic factor, nerve growth factor (NGF), and the chemorepellent factors, semaphorin 3 A (SEMA3A) and SLIT1. The effects of direct and local administration of each agent on axonal projection were evaluated by immunohistochemistry, real-time polymerase chain reaction (PCR), and real-time imaging, in which the filopodia of the growth cone served as an excellent marker. A locally sustained agent system showed that the axons elongate towards NGF, but were repelled by SEMA3A and SLIT1. Focally transplanted beads that released SLIT1 bent the pathfinding of axons, imitating normal retinal development. Our innovative system for assessing the effects of chemical compounds using human RGCs may facilitate development of novel drugs for the examination, prophylaxis, and treatment of diseases. It may also be useful for observing the physiology of the optic nerve in vitro, which might lead to significant progress in the science of human RGCs. PMID- 29196713 TI - A hybrid strain and thermal energy harvester based on an infra-red sensitive Er3+ modified poly(vinylidene fluoride) ferroelectret structure. AB - In this paper, a novel infra-red (IR) sensitive Er3+ modified poly(vinylidene fluoride) (PVDF) (Er-PVDF) film is developed for converting both mechanical and thermal energies into useful electrical power. The addition of Er3+ to PVDF is shown to improve piezoelectric properties due to the formation of a self polarized ferroelectric beta-phase and the creation of an electret-like porous structure. In addition, we demonstrate that Er3+ acts to enhance heat transfer into the Er-PVDF film due to its excellent infrared absorbance, which, leads to rapid and large temperature fluctuations and improved pyroelectric energy transformation. We demonstrate the potential of this novel material for mechanical energy harvesting by creating a durable ferroelectret energy harvester/nanogenerator (FTNG). The high thermal stability of the beta-phase enables the FTNG to harvest large temperature fluctuations (DeltaT ~ 24 K). Moreover, the superior mechanosensitivity, SM ~ 3.4 VPa-1 of the FTNG enables the design of a wearable self-powered health-care monitoring system by human-machine integration. The combination of rare-earth ion, Er3+ with the ferroelectricity of PVDF provides a new and robust approach for delivering smart materials and structures for self-powered wireless technologies, sensors and Internet of Things (IoT) devices. PMID- 29196714 TI - Screening and identification of lncRNAs as potential biomarkers for pulmonary tuberculosis. AB - Pulmonary tuberculosis (TB) is among the diseases with the highest morbidity and mortality worldwide. Effective diagnostic methods for TB are lacking. In this study, we investigated long non-coding RNAs (lncRNAs) in plasma using microarray and the potential diagnostic value of lncRNAs for TB. We found a total of 163 up regulated lncRNAs and 348 down-regulated lncRNAs. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and coding-noncoding co-expression (CNC) analyses showed that functions of differentially expressed lncRNAs were mainly enriched in the regulation of alpha-beta T cell activation and the T cell receptor signalling pathway. Four differentially expressed lncRNAs, NR_038221 (fold change = 3.79, P < 0.01), NR_003142 (fold change = 1.69, P < 0.05), ENST00000570366 (fold change = 3.04, P < 0.05), and ENST00000422183 (fold change = 2.11, P < 0.001), were verified using RT-qPCR. Among those, NR_038221, NR_003142, and ENST00000570366 were found to be up-regulated, while ENST00000422183 was down-regulated. The value of the area under the curve (AUC) for the diagnostic model consisting of the four lncRNAs was 0.845 (sensitivity = 79.2%, specificity = 75%). We further predicted 85 mRNAs and 404 miRNAs that potentially interact with these lncRNAs. Our study revealed the potential value of lncRNAs as biomarkers for early diagnosis of TB and the underlying mechanisms of these abnormally expressed lncRNAs in the pathogenesis of TB. PMID- 29196715 TI - Optimization of segmented thermoelectric generator using Taguchi and ANOVA techniques. AB - Recent studies have demonstrated that segmented thermoelectric generators (TEGs) can operate over large thermal gradient and thus provide better performance (reported efficiency up to 11%) as compared to traditional TEGs, comprising of single thermoelectric (TE) material. However, segmented TEGs are still in early stages of development due to the inherent complexity in their design optimization and manufacturability. In this study, we demonstrate physics based numerical techniques along with Analysis of variance (ANOVA) and Taguchi optimization method for optimizing the performance of segmented TEGs. We have considered comprehensive set of design parameters, such as geometrical dimensions of p-n legs, height of segmentation, hot-side temperature, and load resistance, in order to optimize output power and efficiency of segmented TEGs. Using the state-of-the art TE material properties and appropriate statistical tools, we provide near optimum TEG configuration with only 25 experiments as compared to 3125 experiments needed by the conventional optimization methods. The effect of environmental factors on the optimization of segmented TEGs is also studied. Taguchi results are validated against the results obtained using traditional full factorial optimization technique and a TEG configuration for simultaneous optimization of power and efficiency is obtained. PMID- 29196716 TI - Disrupted superior collicular activity may reveal cervical dystonia disease pathomechanisms. AB - Cervical dystonia is a common neurological movement disorder characterised by muscle contractions causing abnormal movements and postures affecting the head and neck. The neural networks underpinning this condition are incompletely understood. While animal models suggest a role for the superior colliculus in its pathophysiology, this link has yet to be established in humans. The present experiment was designed to test the hypothesis that disrupted superior collicular processing is evident in affected patients and in relatives harbouring a disease specific endophenotype (abnormal temporal discrimination). The study participants were 16 cervical dystonia patients, 16 unaffected first-degree relatives with abnormal temporal discrimination, 16 unaffected first-degree relatives with normal temporal discrimination and 16 healthy controls. The response of participant's superior colliculi to looming stimuli was assessed by functional magnetic resonance imaging. Cervical dystonia patients and relatives with abnormal temporal discrimination demonstrated (i) significantly reduced superior collicular activation for whole brain and region of interest analysis; (ii) a statistically significant negative correlation between temporal discrimination threshold and superior collicular peak values. Our results support the hypothesis that disrupted superior collicular processing is involved in the pathogenesis of cervical dystonia. These findings, which align with animal models of cervical dystonia, shed new light on pathomechanisms in humans. PMID- 29196717 TI - Culturomics and Amplicon-based Metagenomic Approaches for the Study of Fungal Population in Human Gut Microbiota. AB - Herein, the mycobiota was characterized in fecal samples from sick patients and healthy subjects, collected from different geographical locations and using both culturomics and amplicon-based metagenomics approaches. Using the culturomics approach, a total of 17,800 fungal colonies were isolated from 14 fecal samples, and resulted in the isolation of 41 fungal species, of which 10 species had not been previously reported in the human gut. Deep sequencing of fungal-directed ITS1 and ITS2 amplicons led to the detection of a total of 142 OTUs and 173 OTUs from the ITS1 and ITS2 regions, respectively. Ascomycota composed the largest fraction of the total OTUs analyzed (78.9% and 68.2% of the OTUs from the ITS1 and ITS2 regions, respectively), followed by Basidiomycota (16.9% and 30.1% of the OTUs from the ITS1 and ITS2 regions, respectively). Interestingly, the results demonstrate that the ITS1/ITS2 amplicon sequencing provides different information about gut fungal communities compared to culturomics, though both approaches complete each other in assessing fungal diversity in fecal samples. We also report higher fungal diversity and abundance in patients compared to healthy subjects. In conclusion, combining both culturomic and amplicon-based metagenomic approaches may be a novel strategy towards analyzing fungal compositions in the human gut.

PMID- 29196720 TI - Addition of a histone deacetylase inhibitor increases recombinant protein expression in Medicago truncatula cell cultures. AB - Plant cell cultures are an attractive platform for the production of recombinant proteins. A major drawback, hindering the establishment of plant cell suspensions as an industrial platform, is the low product yield obtained thus far. Histone acetylation is associated with increased transcription levels, therefore it is expected that the use of histone deacetylase inhibitors would result in an increase in mRNA and protein levels. Here, this hypothesis was tested by adding a histone deacetylase inhibitor, suberanilohydroxamic acid (SAHA), to a cell line of the model legume Medicago truncatula expressing a recombinant human protein. Histone deacetylase inhibition by SAHA and histone acetylation levels were studied, and the effect of SAHA on gene expression and recombinant protein levels was assessed by digital PCR. SAHA addition effectively inhibited histone deacetylase activity resulting in increased histone acetylation. Higher levels of transgene expression and accumulation of the associated protein were observed. This is the first report describing histone deacetylase inhibitors as inducers of recombinant protein expression in plant cell suspensions as well as the use of digital PCR in these biological systems. This study paves the way for employing epigenetic strategies to improve the final yields of recombinant proteins produced by plant cell cultures. PMID- 29196721 TI - On the effect of low oxygen concentrations on bacterial degradation of sinking particles. AB - In marine oxygen (O2) minimum zones (OMZs), the transfer of particulate organic carbon (POC) to depth via the biological carbon pump might be enhanced as a result of slower remineralisation under lower dissolved O2 concentrations (DO). In parallel, nitrogen (N) loss to the atmosphere through microbial processes, such as denitrification and anammox, is directly linked to particulate nitrogen (PN) export. However it is unclear (1) whether DO is the only factor that potentially enhances POC transfer in OMZs, and (2) if particle fluxes are sufficient to support observed N loss rates. We performed a degradation experiment on sinking particles collected from the Baltic Sea, where anoxic zones are observed. Sinking material was harvested using surface-tethered sediment traps and subsequently incubated in darkness at different DO levels, including severe suboxia (<0.5 mg l-1 DO). Our results show that DO plays a role in regulating POC and PN degradation rates. POC(PN) degradation was reduced by approximately 100% from the high to low DO to the lowest DO. The amount of NH4+ produced from the pool of remineralising organic N matched estimations of NH4+ anammox requirements during our experiment. This anammox was likely fueled by DON degradation rather than PON degradation. PMID- 29196718 TI - The role of the systemic inflammatory response in predicting outcomes in patients with operable cancer: Systematic review and meta-analysis. AB - Cancer remains a leading causes of death worldwide and an elevated systemic inflammatory response (SIR) is associated with reduced survival in patients with operable cancer. This review aims to examine the evidence for the role of systemic inflammation based prognostic scores in patients with operable cancers. A wide-ranging literature review using targeted medical subject headings for human studies in English was carried out in the MEDLINE, EMBASE, and CDSR databases until the end of 2016. The SIR has independent prognostic value, across tumour types and geographical locations. In particular neutrophil lymphocyte ratio (NLR) (n = 158), platelet lymphocyte ratio (PLR) (n = 68), lymphocyte monocyte ratio (LMR) (n = 21) and Glasgow Prognostic Score/ modified Glasgow Prognostic Score (GPS/mGPS) (n = 60) were consistently validated. On meta analysis there was a significant relationship between elevated NLR and overall survival (OS) (p < 0.00001)/ cancer specific survival (CSS) (p < 0.00001), between elevated LMR and OS (p < 0.00001)/CSS (p < 0.00001), and elevated PLR and OS (p < 0.00001)/CSS (p = 0.005). There was also a significant relationship between elevated GPS/mGPS and OS (p < 0.00001)/CSS (p < 0.00001). These results consolidate the prognostic value of the NLR, PLR, LMR and GPS/mGPS in patients with resectable cancers. This is particularly true for the NLR/GPS/mGPS which should form part of the routine preoperative and postoperative workup. PMID- 29196722 TI - Abstract spatial, but not body-related, visual information guides bimanual coordination. AB - Visual spatial information is paramount in guiding bimanual coordination, but anatomical factors, too, modulate performance in bimanual tasks. Vision conveys not only abstract spatial information, but also informs about body-related aspects such as posture. Here, we asked whether, accordingly, visual information induces body-related, or merely abstract, perceptual-spatial constraints in bimanual movement guidance. Human participants made rhythmic, symmetrical and parallel, bimanual index finger movements with the hands held in the same or different orientations. Performance was more accurate for symmetrical than parallel movements in all postures, but additionally when homologous muscles were concurrently active, such as when parallel movements were performed with differently rather than identically oriented hands. Thus, both perceptual and anatomical constraints were evident. We manipulated visual feedback with a mirror between the hands, replacing the image of the right with that of the left hand and creating the visual impression of bimanual symmetry independent of the right hand's true movement. Symmetrical mirror feedback impaired parallel, but improved symmetrical bimanual performance compared with regular hand view. Critically, these modulations were independent of hand posture and muscle homology. Thus, visual feedback appears to contribute exclusively to spatial, but not to body related, anatomical movement coding in the guidance of bimanual coordination. PMID- 29196723 TI - Bayesian Analysis of MicroScale Thermophoresis Data to Quantify Affinity of Protein:Protein Interactions with Human Survivin. AB - A biomolecular ensemble exhibits different responses to a temperature gradient depending on its diffusion properties. MicroScale Thermophoresis technique exploits this effect and is becoming a popular technique for analyzing interactions of biomolecules in solution. When comparing affinities of related compounds, the reliability of the determined thermodynamic parameters often comes into question. The thermophoresis binding curves can be assessed by Bayesian inference, which provides a probability distribution for the dissociation constant of the interacting partners. By applying Bayesian machine learning principles, binding curves can be autonomously analyzed without manual intervention and without introducing subjective bias by outlier rejection. We demonstrate the Bayesian inference protocol on the known survivin:borealin interaction and on the putative protein-protein interactions between human survivin and two members of the human Shugoshin-like family (hSgol1 and hSgol2). These interactions were identified in a protein microarray binding assay against survivin and confirmed by MicroScale Thermophoresis. PMID- 29196724 TI - Hierarchically porous, and Cu- and Zn-containing gamma-AlOOH mesostrands as adjuvants for cancer immunotherapy. AB - Alum is the only licensed adjuvant by Food and Drug Administration of USA used in many human vaccines and has excellent safety record in clinical applications. However, alum hardly induces T helper 1 (Th1) immune responses that are required for anti-tumor immunity. In the present study, we fabricated hierarchical copper- and zinc- buds dressing gamma-AlOOH mesostrands (Cu- and Zn-AMSs) with randomly wrinkled morphology, mesoscale void- or cave-like pockets, high-exposed surface coverage sites, and positive charge streams in saline. We confirmed that Cu- and Zn-AMSs promoted intracellular uptake of model cancer antigen (ovalbumin, OVA) by THP-1-differentiated macrophage-like cells in vitro. Moreover, Cu- and Zn-AMSs enhanced maturation and cytokine release of bone marrow dendritic cells in vitro. In vivo study demonstrated that Cu- and Zn-AMSs markedly induced anti-tumor immunity and enhanced CD4+ and CD8+ T cell populations in splenocytes of mice. These findings demonstrated that hierarchical copper- and zinc- buds dressing gamma-AlOOH mesostrands, which are oriented in randomly wrinkled matrice, are suitable platforms as novel adjuvants for cancer immunotherapy. PMID- 29196725 TI - Pharmacogenetic study of seven polymorphisms in three nicotinic acetylcholine receptor subunits in smoking-cessation therapies. AB - Smoking-cessation therapy reduces the risk of smoking-related diseases, but is successful only in a fraction of smokers. There is growing evidence that genetic variations in nicotinic acetylcholine receptor (nAChR) subunits influence the risk of nicotine dependence and the ability to quit smoking. To investigate the role of polymorphisms in nAChR genes on smoking quantity and the outcome of smoking-cessation therapies, we carried out an association study on 337 smokers who underwent pharmacotherapy with varenicline, bupropion, nicotine replacement therapy (NRT) alone, or NRT plus bupropion. Smoking habit and abstention were assessed from the number of cigarettes smoked per day (CPD) and the exhaled CO (eCO), at baseline and up to 12 months. We genotyped seven polymorphisms in genes encoding the nAChR subunits CHRNA4, CHRNA5, and CHRNB2. At baseline, both CPD and eCO were associated with polymorphisms in the CHRNA5 locus (rs503464, rs55853698, rs55781567 and rs16969968; P < 0.01). rs503464, a variant in the 5'-UTR of CHRNA5, was also associated with short-, mid- and long-term responses to therapy (P = 0.011, P = 0.0043, P = 0.020, respectively), although after correction for multiple testing only the association at the mid-term assessment remained significant (FDR = 0.03). These data support the role of individual genetic makeup in the ability to quit smoking. PMID- 29196726 TI - Emergence of BA9 genotype of human respiratory syncytial virus subgroup B in China from 2006 to 2014. AB - A study was conducted to investigate the circulation of HRSV subgroup B (HRSVB) in China in recent years. HRSVB sequences from 365 samples collected in 1991, 2004 and 2008-2014 in China, together with 332 Chinese HRSVB sequences obtained from GenBank were analyzed to determine the geographic and yearly distribution of HRSVB. Phylogenetic analysis revealed these HRSVB sequences clustered into 4 genotypes with different frequencies: BA (83%), CB1 (11%), SAB (3.0%) and GB3 (0.7%). Between 2005 and 2013, there was a co-circulation of BA and non-BA genotypes in China. Genotypes BA9 and BA10 were two of the main BA genotypes detected in this study. Genotype BA9 was first detected in China in 2006 and became the predominant HRSVB genotype circulating in China from 2008 to 2014. Three different lineages were detected for both genotypes BA9 and BA10. Time to the most recent common ancestor for genotypes BA9 and BA10 was estimated for years 1997 and 1996, respectively. Results of this study not only contribute to the understanding of the circulation pattern, but also the phylogenetic pattern and evolution of HRSVB in China from 1991 to 2014. PMID- 29196727 TI - Hypersensitivity of BRCA2 deficient cells to rosemary extract explained by weak PARP inhibitory activity. AB - Rosemary extract is used in food additives and traditional medicine and has been observed to contain anti-tumor activity. In this study, rosemary extract is hypothesized to induce synthetic lethality in BRCA2 deficient cells by PARP inhibition. Chinese hamster lung V79 cells and its mutant cell lines, V-C8 (BRCA2 deficient) and V-C8 with BRCA2 gene correction were used. Rosemary extract and its major constituent chemicals were tested for their cytotoxicity by colony formation assay in cells of different BRCA2 status. The latter chemicals were tested for inhibitory effect of poly (ADP-ribose) polymerase (PARP) activity in vitro and in vivo. Rosemary has shown selective cytotoxicity against V-C8 cells (IC50 17 ug/ml) compared to V79 cells (IC50 26 ug/ml). Among tested chemicals, gallic acid and carnosic acid showed selective cytotoxicity to V-C8 cells along with PARP inhibitory effects. Carnosol showed comparative PARP inhibitory effects at 100 uM compared to carnosic acid and gallic acid, but the selective cytotoxicity was not observed. In conclusion, we predict that within rosemary extract two specific constituent components; gallic acid and carnosic acid were the cause for the synthetic lethality. PMID- 29196728 TI - Diverse and complex male polymorphisms in Odontolabis stag beetles (Coleoptera: Lucanidae). AB - When male animals engage in intrasexual contests then any alternative tactics they use can be associated with dimorphisms in the expression of weapons. Some species have recently been found to exhibit trimorphism in their weaponry, suggesting that the processes leading to their evolution and maintenance of these polymorphisms can be more complex than previously thought. Here, we describe the extraordinary diversity of polymorphism within the genus Odontolabis: there are dimorphic species (O. siva and O. platynota), trimorphic species (O. cuvera, as previously described, and O. sommeri s.stricto) and, uniquely, tetramorphic species, with males of O. sommeri lowei and O. brookeana showing four clearly differentiated male morphs: small "Gammas", "Alphas" which express large, long mandibles, "Betas" which have long mandibles with different morphology and "Boltcutters", with short, wide mandibles. Such polymorphisms are usually thought of as being maintained as a status-dependent conditional strategy, but we found only one size threshold: in most cases males develop into Gamma males below a certain size but there is no relationship between morph and body size amongst the larger, 'weaponised' morphs. We suggest that the complex polymorphisms in these animals are probably maintained by a combination of a conditional strategy and a genetic polymorphism.

AB - Soil heavy metals exhibit significant spatiotemporal variability and are strongly correlated with other soil heavy metals. Thus, other heavy metals can be used to improve the accuracy of predictions when performing spatiotemporal predictions of soil heavy metals within a given area. In this study, we propose the spatiotemporal cokriging (STCK) method to enable the use of historical sampling points and co-variables in the spatial prediction of soil heavy metals. Moreover, experimental spatiotemporal (ST) semivariogram and ST cross-semivariogram computational methods, a fitting strategy to the ST semivariogram and ST cross semivariogram models based on the Bilonick model, and the STCK interpolation algorithm are introduced; these methods are based on spatiotemporal kriging (STK) and cokriging (CK). The data used in this study consist of measurements of soil heavy metals from 2010 to 2014 in Wuhan City, China. The results show that the behavior of predictions of the concentrations of heavy metals in soils is physically more realistic, and the prediction uncertainties are slightly smaller, when STCK is used with greater numbers of co-variables and neighboring points.

AB - HIV latency is the main barrier to HIV eradication. Peripheral T follicular helper (pTfh) cells have a prominent role in HIV persistence. Herein, we analyzed the HIV reservoir size within memory CD4+ T-cell subsets in patients with HIV replication control. Twenty HIV-infected patients with suppressed HIV replication were included, with 10 elite controllers (EC) and 10 treated (TX) individuals. The HIV reservoir size was analyzed in resting memory CD4+ T-cells (Trm), pTfh, and non-pTfh cells using an ultrasensitive digital-droplet-PCR assay. Inter-group and intra-group differences were tested using non-parametric tests. Compared with the TX patients, the EC patients had smaller HIV reservoir not only in Trm but also in pTfh and non-pTfh subsets of memory CD4+ T-cells. The largest differences were observed in pTfh cells (p = 0.025). The pTfh and non-pTfh cells harbored similar levels of HIV-DNA in the EC (p = 0.60) and TX patients (p = 0.17); however, the contribution to HIV-DNA levels in memory CD4+ T-cells varied among the pTfh and non-pTfh subsets in both groups of patients. The EC patients showed smaller HIV reservoir in memory CD4+ cells, especially in the pTfh subset, a population of cells with a pivotal role in the antiviral immune response, suggesting a potential link between low levels of infection in pTfh cells and the ability of the EC patients to spontaneously control HIV replication. PMID- 29196731 TI - Influenza virus Matrix Protein M1 preserves its conformation with pH, changing multimerization state at the priming stage due to electrostatics. AB - Influenza A virus matrix protein M1 plays an essential role in the virus lifecycle, but its functional and structural properties are not entirely defined. Here we employed small-angle X-ray scattering, atomic force microscopy and zeta potential measurements to characterize the overall structure and association behavior of the full-length M1 at different pH conditions. We demonstrate that the protein consists of a globular N-terminal domain and a flexible C-terminal extension. The globular N-terminal domain of M1 monomers appears preserved in the range of pH from 4.0 to 6.8, while the C-terminal domain remains flexible and the tendency to form multimers changes dramatically. We found that the protein multimerization process is reversible, whereby the binding between M1 molecules starts to break around pH 6. A predicted electrostatic model of M1 self-assembly at different pH revealed a good agreement with zeta-potential measurements, allowing one to assess the role of M1 domains in M1-M1 and M1-lipid interactions. Together with the protein sequence analysis, these results provide insights into the mechanism of M1 scaffold formation and the major role of the flexible and disordered C-terminal domain in this process. PMID- 29196732 TI - Human CRMP4 mutation and disrupted Crmp4 expression in mice are associated with ASD characteristics and sexual dimorphism. AB - Autism spectrum disorders (ASD) are more common among boys than girls. The mechanisms responsible for ASD symptoms and their sex differences remain mostly unclear. We previously identified collapsin response mediator protein 4 (CRMP4) as a protein exhibiting sex-different expression during sexual differentiation of the hypothalamic sexually dimorphic nucleus. This study investigated the relationship between the sex-different development of autistic features and CRMP4 deficiency. Whole-exome sequencing detected a de novo variant (S541Y) of CRMP4 in a male ASD patient. The expression of mutated mouse CRMP4 S540Y, which is homologous to human CRMP4 S541Y, in cultured hippocampal neurons derived from Crmp4-knockout (KO) mice had increased dendritic branching, compared to those transfected with wild-type (WT) Crmp4, indicating that this mutation results in altered CRMP4 function in neurons. Crmp4-KO mice showed decreased social interaction and several alterations of sensory responses. Most of these changes were more severe in male Crmp4-KO mice than in females. The mRNA expression levels of some genes related to neurotransmission and cell adhesion were altered in the brain of Crmp4-KO mice, mostly in a gender-dependent manner. These results indicate a functional link between a case-specific, rare variant of one gene, Crmp4, and several characteristics of ASD, including sexual differences. PMID- 29196733 TI - Regulation of HMGB3 by antitumor miR-205-5p inhibits cancer cell aggressiveness and is involved in prostate cancer pathogenesis. AB - Our recent determination of a microRNA (miRNA) expression signature in prostate cancer (PCa) revealed that miR-205-5p was significantly reduced in PCa tissues and that it acted as an antitumor miRNA. The aim of this study was to identify oncogenic genes and pathways in PCa cells that were regulated by antitumor miR 205-5p. Genome-wide gene expression analyses and in silico miRNA database searches showed that 37 genes were putative targets of miR-205-5p regulation. Among those genes, elevated expression levels of seven in particular (HMGB3, SPARC, MKI67, CENPF, CDK1, RHOU, and POLR2D) were associated with a shorter disease-free survival in a large number of patients in the The Cancer Genome Atlas (TCGA) database. We focused on high-mobility group box 3 (HMGB3) because it was the most downregulated by ectopic expression of miR-205-5p in PC3 cells and its expression was involved in PCa pathogenesis. Luciferase reporter assays showed that HMGB3 was directly regulated by miR-205-5p in PCa cells. Knockdown studies using si-HMGB3 showed that expression of HMGB3 enhanced PCa cell aggressiveness. Overexpression of HMGB3/HMGB3 was confirmed in naive PCa and castration-resistant PCa (CRPC) clinical specimens. Novel approaches to analysis of antitumor miRNA-regulated RNA networks in PCa cells may provide new insights into the pathogenic mechanisms of the disease. PMID- 29196734 TI - Possible Tomonaga-Luttinger spin liquid state in the spin-1/2 inequilateral diamond-chain compound K3Cu3AlO2(SO4)4. AB - K3Cu3AlO2(SO4)4 is a highly one-dimensional spin-1/2 inequilateral diamond-chain antiferromagnet. Spinon continuum and spin-singlet dimer excitations are observed in the inelastic neutron scattering spectra, which is in excellent agreement with a theoretical prediction: a dimer-monomer composite structure, where the dimer is caused by strong antiferromagnetic (AFM) coupling and the monomer forms an almost isolated quantum AFM chain controlling low-energy excitations. Moreover, muon spin rotation/relaxation spectroscopy shows no long-range ordering down to 90 mK, which is roughly three orders of magnitude lower than the exchange interaction of the quantum AFM chain. K3Cu3AlO2(SO4)4 is, thus, regarded as a compound that exhibits a Tomonaga-Luttinger spin liquid behavior at low temperatures close to the ground state. PMID- 29196735 TI - Considerations for spectroscopy of liquid-exfoliated 2D materials: emerging photoluminescence of N-methyl-2-pyrrolidone. AB - N-methyl-2-pyrrolidone (NMP) has been shown to be the most effective solvent for liquid phase exfoliation and dispersion of a range of 2D materials including graphene, molybdenum disulphide (MoS2) and black phosphorus. However, NMP is also known to be susceptible to sonochemical degradation during exfoliation. We report that this degradation gives rise to strong visible photoluminescence of NMP. Sonochemical modification is shown to influence exfoliation of layered materials in NMP and the optical absorbance of the solvent in the dispersion. The emerging optical properties of the degraded solvent present challenges for spectroscopy of nanomaterial dispersions; most notably the possibility of observing solvent photoluminescence in the spectra of 2D materials such as MoS2, highlighting the need for stable solvents and exfoliation processes to minimise the influence of solvent degradation on the properties of liquid-exfoliated 2D materials. PMID- 29196736 TI - Continuous positive airway pressure delivery during less invasive surfactant administration: a physiologic study. AB - OBJECTIVE: We sought to investigate the pressure delivery during less invasive surfactant administration, as we hypothesize that it might be reduced. STUDY DESIGN: Physiologic in vitro study in a ventilation lab, using different pressure generators, levels, and leaks in a model of neonatal airways/lung mimicking mechanical characteristics of respiratory distress syndrome. Pressure was measured at the lung and verified in vivo measuring pharyngeal pressure in 19 neonates under same conditions. Data were analyzed using repeated measures analysis of variance. RESULTS: Pressure delivery in vitro is significantly and variably reduced during minimally invasive surfactant administration: pressure loss is ~99% and ~10-97%, during mouth opening and closure, respectively. Pressure loss seems independent from the type of CPAP and interface. In vivo measurements showed similar pressure drops. CONCLUSIONS: Pressure transmission during minimally invasive surfactant administration is significantly reduced or totally absent. Pressure drop occurs despite the increased airway resistances and the airflow limitation due to the tracheal catheterization, but is independent from the type of pressure generator and interface. PMID- 29196737 TI - Spontaneous Phase Transfer-Mediated Selective Removal of Heavy Metal Ions Using Biocompatible Oleic Acid. AB - Here, we propose an environmentally benign removal technique for heavy metal ions based on selective and spontaneous transfer to oleic acid. The ions can be removed via (1) the selective and rapid complexation with the carboxylic end of oleic acid at an oleic acid/water interface, and (2) the diffusion of such complex into the oleic acid layer. A wide variety of heavy metal ions such as Cu2+, Pb2+, Zn2+, and Ni2+ can be selectively removed over K+ and Na+. For example, the concentration of Cu2+ is reduced to below 1.3 ppm within 24 h, which corresponds to the level of Cu2+ permitted by the Environmental Protection Agency. The addition of ethylenediamine ligand to the metal ion solutions is also shown to enhance the phase transfer. The removal efficiency is increased by up to 6 times when compared with that in the absence of the ligand and follows the order, Cu2+ (99%) > Pb2+ (96%) > Zn2+ (95%) > Ni2+ (65%). Moreover, the removal time can be shortened from 24 h to 1 h. The effect of an emulsion induced by a mechanical agitation on the removal of heavy metal ion is also studied. PMID- 29196738 TI - Validation of SinoSCORE for isolated CABG operation in East China. AB - From January 2010 to December 2016, 1616 consecutive patients who underwent isolated coronary artery bypass grafting (CABG) were evaluated for their predicted mortality according to the online Sino System for Coronary Operative Risk Evaluation (SinoSCORE), European System for Cardiac Operative Risk Evaluation II (EuroSCORE II) and Society of Thoracic Surgeons (STS) risk evaluation system. The calibration and discrimination in the total and in the subsets were assessed by the Hosmer-Lemeshow (H-L) statistics and by the C statistics respectively, to evaluate the efficiency of the three risk evaluation systems. The realized mortality was 1.92% (31/1616). The predictive mortality of SinoSCORE, EuroSCORE II and STS risk evaluation system were 1.35%, 1.74% and 1.05%, respectively. SinoSCORE achieved best discrimination. When grouping by risk, SinoSCORE also achieved the best discrimination in high-risk group, followed by STS risk evaluation system and EuroSCORE II while SinoSCORE and EuroSCORE II had excellent performance in low-risk group. In terms of calibration, SinoSCORE, EuroSCORE II and STS risk evaluation system all achieved positive calibrations (H-L: P > 0.05) in the overall population and grouped subsets. SinoSCORE achieved good predictive efficiency in East China patients undergoing isolated CABG and showed no compromise when compared with EuroSCORE II and STS risk evaluation system.

AB - Abnormalities of mucus viscosity play a critical role in the pathogenesis of several respiratory diseases, including cystic fibrosis. Currently, there are no approaches to assess the rheological properties of mucin granule matrices in live cells. This is the first example of the use of a molecular rotor, a BODIPY dye, to quantitatively visualize the viscosity of intragranular mucin matrices in a large population of individual granules in differentiated primary bronchial epithelial cells using fluorescence lifetime imaging microscopy. PMID- 29196740 TI - Rapid and Sensitive SERS Detection of Bisphenol A Using Self-assembled Graphitic Substrates. AB - We have prepared and tested a new surface enhanced Raman scattering (SERS) substrate based on self-assembled graphitic sheets to detect bisphenol A (BPA) in plastic consumer goods. Transmission electron microscopy (TEM) and atomic-force microscopy (AFM) were used to characterize the structure of the graphitic sheets and showed a lattice spacing of 0.24 nm and layer height of 0.34 nm. These values were comparable to single monolayer graphene. The effective SERS detection limit of this method is 1 MUM BPA, which is lower than the European Union specific migration limit for BPA of 0.6 mg/kg (2.6 MUM). When used in salt solutions, graphitic sheets exhibited ultra-sensitivity toward BPA of 0.025 M to 2 M, which was broader than physiological ionic strength (0.14 M) and urinary NaCl (0.17 M). Our results demonstrated that this graphitic sheet based SERS detection platform can be used to determine BPA levels leached from commercial polycarbonate plastic products and for on-site rapid analysis with good results. PMID- 29196741 TI - Bayesian inference of epidemiological parameters from transmission experiments. AB - Epidemiological parameters for livestock diseases are often inferred from transmission experiments. However, there are several limitations inherent to the design of such experiments that limits the precision of parameter estimates. In particular, infection times and latent periods cannot be directly observed and infectious periods may also be censored. We present a Bayesian framework accounting for these features directly and employ Markov chain Monte Carlo techniques to provide robust inferences and quantify the uncertainty in our estimates. We describe the transmission dynamics using a susceptible-exposed infectious-removed compartmental model, with gamma-distributed transition times. We then fit the model to published data from transmission experiments for foot and-mouth disease virus (FMDV) and African swine fever virus (ASFV). Where the previous analyses of these data made various assumptions on the unobserved processes in order to draw inferences, our Bayesian approach includes the unobserved infection times and latent periods and quantifies them along with all other model parameters. Drawing inferences about infection times helps identify who infected whom and can also provide insights into transmission mechanisms. Furthermore, we are able to use our models to measure the difference between the latent periods of inoculated and contact-challenged animals and to quantify the effect vaccination has on transmission. PMID- 29196742 TI - Whitening and Impaired Glucose Utilization of Brown Adipose Tissue in a Rat Model of Type 2 Diabetes Mellitus. AB - Brown adipose tissue (BAT) is an attractive therapeutic target to combat diabetes and obesity due to its ability to increase glucose expenditure. In a genetic rat model (ZDF fa/fa) of type-2 diabetes and obesity, we aimed to investigate glucose utilization of BAT by 18F-FDG PET imaging. Male Zucker diabetic fatty (ZDF) and Male Zucker lean (ZL) control rats were studied at 13 weeks. Three weeks prior to imaging, ZDF rats were randomized into a no-restriction (ZDF-ND) and a mild calorie restriction (ZDF-CR) group. Dynamic 18F-FDG PET using a dedicated small animal PET system was performed under hyperinsulinemic-euglycemic clamp. 18F-FDG PET identified intense inter-scapular BAT glucose uptake in all ZL control rats, while no focally increased 18F-FDG uptake was detected in all ZDF-ND rats. Mild but significant improved BAT tracer uptake was identified after calorie restriction in diabetic rats (ZDF-CR). The weight of BAT tissue and fat deposits were significantly increased in ZDF-CR and ZDF-ND rats as compared to ZL controls, while UCP-1 and mitochondrial concentrations were significantly decreased. Whitening and severely impaired insulin-stimulated glucose uptake in BAT was confirmed in a rat model of type-2 diabetes. Additionally, calorie restriction partially restored the impaired BAT glucose uptake. PMID- 29196743 TI - Repair of the TGFBI gene in human corneal keratocytes derived from a granular corneal dystrophy patient via CRISPR/Cas9-induced homology-directed repair. AB - Granular corneal dystrophy (GCD) is an autosomal dominant hereditary disease in which multiple discrete and irregularly shaped granular opacities are deposited in the corneal stroma. GCD is caused by a point mutation in the transforming growth factor-beta-induced (TGFBI) gene, located on chromosome 5q31. Here, we report the first successful application of CRISPR-Cas9-mediated genome editing for the correction of a TGFBI mutation in GCD patient-derived primary corneal keratocytes via homology-directed repair (HDR). To correct genetic defects in GCD patient cells, we designed a disease-specific guide RNA (gRNA) targeting the R124H mutation of TGFBI, which causes GCD type 2 (GCD2). An R124H mutation in primary human corneal keratocytes derived from a GCD2 patient was corrected by delivering a CRISPR plasmid expressing Cas9/gRNA and a single-stranded oligodeoxynucleotide HDR donor template in vitro. The gene correction efficiency was 20.6% in heterozygous cells and 41.3% in homozygous cells. No off-target effects were detected. These results reveal a new therapeutic strategy for GCD2; this method may also be applicable to other heredity corneal diseases. PMID- 29196744 TI - A simple high throughput assay to evaluate water consumption in the fruit fly. AB - Water intake is essential for survival and thus under strong regulation. Here, we describe a simple high throughput system to monitor water intake over time in Drosophila. The design of the assay involves dehydrating fly food and then adding water back separately so flies either eat or drink. Water consumption is then evaluated by weighing the water vessel and comparing this back to an evaporation control. Our system is high throughput, does not require animals to be artificially dehydrated, and is simple both in design and implementation. Initial characterisation of homeostatic water consumption shows high reproducibility between biological replicates in a variety of experimental conditions. Water consumption was dependent on ambient temperature and humidity and was equal between sexes when corrected for mass. By combining this system with the Drosophila genetics tools, we could confirm a role for ppk28 and DopR1 in promoting water consumption, and through functional investigation of RNAseq data from dehydrated animals, we found DopR1 expression in the mushroom body was sufficient to drive consumption and enhance water taste sensitivity. Together, we provide a simple high throughput water consumption assay that can be used to dissect the cellular and molecular machinery regulating water homeostasis in Drosophila. PMID- 29196745 TI - Characterization of liposomal carriers for the trans-scleral transport of Ranibizumab. AB - Age-related macular degeneration (AMD) is a leading cause of blindness in the modern world. The standard treatment regimen for neovascular AMD is the monthly/bimonthly intravitreal injection of anti-VEGF agents such as ranibizumab or aflibercept. However, these repeated invasive injections can lead to sight threatening complications. Sustained delivery by encapsulation of the drug in carriers is a way to reduce the frequency of these injections. Liposomes are biocompatible, non-toxic vesicular nanocarriers, which can be used to encapsulate therapeutic agents to provide sustained release. The protein encapsulation was performed by a modified dehydration-rehydration (DRV) method. The liposomes formed were characterized for size, zeta potential, encapsulation efficiency, stability, in vitro release, and ex vivo release profiles. In addition, the localization of the liposomes themselves was studied ex vivo. Entrapment efficiency of ranibizumab into 100-nm liposomes varied from 14.7 to 57.0%. Negatively-charged liposomes prepared from DPPC-DPPG were found to have the slowest release with a low initial burst release compared to the rest of liposomal formulations. The ex vivo protein release was found to slower than the in vitro protein release for all samples. In conclusion, the DPPC-DPPG liposomes significantly improved the encapsulation and release profile of ranibizumab. PMID- 29196747 TI - A small cassette enables conditional gene inactivation by CRISPR/Cas9. AB - The availability of CRISPR/Cas9 technology has enabled the rapid establishment of gene knockouts in many cell types and even whole organisms. However, conditional inactivation of essential genes remains a challenge. We devised an approach named DECAI (DEgradation based on Cre-regulated- Artificial Intron). It utilizes a small cassette of just 201 nucleotides that is inserted into the coding exon of a target gene using CRISPR/Cas9 technology and homology-directed repair. As its sequence is derived from an artificial intron, the cassette is removed by the splicing machinery and thus leaves no trace in the "off-state". Upon activation with Cre recombinase ("on-state"), the intron is crippled and the target gene is disrupted by a series of stop codons. We exemplify the utility of this approach on several non-essential and essential human genes. Clones bearing the conditional knockout cassette are recovered at frequencies above 5% and cassette function can be traced at the genomic DNA and the mRNA level. Importantly, cassette activation leads to loss of gene expression as judged by flow cytometry, Western blot or immunofluorescence. Altogether, this highlights the broad utility of the approach for conditional gene inactivation and suggests that this tool could be used to study the loss-of-function phenotypes of essential genes. PMID- 29196746 TI - Diabetes Aggravates Post-ischaemic Renal Fibrosis through Persistent Activation of TGF-beta1 and Shh Signalling. AB - Diabetes is a risk factor for acute kidney injury (AKI) and chronic kidney disease (CKD). Diabetic patients are easy to progress to CKD after AKI. Currently, activation of fibrotic signalling including transforming growth factor beta1 (TGF-beta1) is recognized as a key mechanism in CKD. Here, we investigated the influence of diabetes on CKD progression after AKI by using a unilateral renal ischaemia-reperfusion injury (IRI) model in diabetic mice. IRI induced extensive tubular injury, fibrosis and lymphocyte recruitment at 3 weeks after IRI, irrespective of diabetes. However, diabetes showed sustained tubular injury and markedly increased fibrosis and lymphocyte recruitment compared with non diabetes at 5 week after IRI. The mRNAs and proteins related to TGF-beta1 and sonic hedgehog (Shh) signalling were significantly higher in diabetic versus non diabetic IRI kidneys. During the in vitro study, the hyperglycaemia induced the activation of TGF-beta1 and Shh signalling and also increased profibrogenic phenotype change. However, hyperglycaemic control with insulin did not improve the progression of renal fibrosis and the activation of TGF-beta1 and Shh signalling. In conclusion, diabetes promotes CKD progression of AKI via activation of the TGF-beta1 and Shh signalling pathways, but insulin treatment was not enough for preventing the progression of renal fibrosis. PMID- 29196748 TI - Cell-Free DNA Kinetics in a Pre-Clinical Model of Head and Neck Cancer. AB - In cancer patients, circulating tumour-derived DNA (ctDNA) levels imperfectly reflect disease burden apparent on medical imaging. Further evaluation of ctDNA levels over time is needed to better understand the correlation with tumour growth and therapeutic response. We describe ctDNA kinetics within an orthotopic, immunocompetent preclinical rabbit model of local-regionally advanced head and neck squamous cell carcinoma (HNSCC). Monitoring primary tumour and metastatic lymph node volume by computed tomography (CT), we observed a correlation between ctDNA levels and tumour burden. We found that ctDNA detection could precede evidence of tumour on CT. Sensitivity and specificity of ctDNA detection in this model was 90.2% (95% C.I.: 76.9-97.3%) and 85.7% (95% C.I.: 67.3-96.0%), respectively. Rapid tumour growth followed by auto-necrosis and tumour volume contraction produced a spike in ctDNA levels, suggesting that viable tumour cells may be required for sustained ctDNA release. Following surgical resection, both ctDNA and total plasma DNA were correlated with recurrent tumour volume. Our results reveal the complex kinetic behaviour of ctDNA and total plasma DNA upon tumour growth or surgery. This pre-clinical model could be useful for future studies focused on elucidating mechanisms of ctDNA release into the circulation from primary and metastatic sites.

AB - The internal quantum efficiency (IQE) of an electrically-driven GaN:Eu based device for red light emission is analyzed in the framework of a current injection efficiency model (CIE). The excitation path of the Eu+3 ion is decomposed in a multiple level system, which includes the carrier transport phenomena across the GaN/GaN:Eu/GaN active region of the device, and the interactions among traps, Eu+3 ions and the GaN host. The identification and analysis of the limiting factors of the IQE are accomplished through the CIE model. The CIE model provides a guidance for high IQE in the electrically-driven GaN:Eu based red light emitters. PMID- 29196751 TI - The solvability of quantum k-pair network in a measurement-based way. AB - Network coding is an effective means to enhance the communication efficiency. The characterization of network solvability is one of the most important topic in this field. However, for general network, the solvability conditions are still a challenge. In this paper, we consider the solvability of general quantum k-pair network in measurement-based framework. For the first time, a detailed account of measurement-based quantum network coding(MB-QNC) is specified systematically. Differing from existing coding schemes, single qubit measurements on a pre-shared graph state are the only allowed coding operations. Since no control operations are concluded, it makes MB-QNC schemes more feasible. Further, the sufficient conditions formulating by eigenvalue equations and stabilizer matrix are presented, which build an unambiguous relation among the solvability and the general network. And this result can also analyze the feasibility of sharing k EPR pairs task in large-scale networks. Finally, in the presence of noise, we analyze the advantage of MB-QNC in contrast to gate-based way. By an instance network [Formula: see text], we show that MB-QNC allows higher error thresholds. Specially, for X error, the error threshold is about 30% higher than 10% in gate based way. In addition, the specific expressions of fidelity subject to some constraint conditions are given. PMID- 29196750 TI - A Novel Y-Specific Long Non-Coding RNA Associated with Cellular Lipid Accumulation in HepG2 cells and Atherosclerosis-related Genes. AB - There is an increasing appreciation for the role of the human Y chromosome in phenotypic differences between the sexes in health and disease. Previous studies have shown that genetic variation within the Y chromosome is associated with cholesterol levels, which is an established risk factor for atherosclerosis, the underlying cause of coronary artery disease (CAD), a major cause of morbidity and mortality worldwide. However, the exact mechanism and potential genes implicated are still unidentified. To date, Y chromosome-linked long non-coding RNAs (lncRNAs) are poorly characterized and the potential link between these new regulatory RNA molecules and hepatic function in men has not been investigated. Advanced technologies of lncRNA subcellular localization and silencing were used to identify a novel intergenic Y-linked lncRNA, named lnc-KDM5D-4, and investigate its role in fatty liver-associated atherosclerosis. We found that lnc KDM5D-4 is retained within the nucleus in hepatocytes. Its knockdown leads to changes in genes leading to increased lipid droplets formation in hepatocytes resulting in a downstream effect contributing to the chronic inflammatory process that underpin CAD. Our findings provide the first evidence for the implication of lnc-KDM5D-4 in key processes related to fatty liver and cellular inflammation associated with atherosclerosis and CAD in men. PMID- 29196752 TI - Combined genetic approaches yield a 48% diagnostic rate in a large cohort of French hearing-impaired patients. AB - Hearing loss is the most common sensory disorder and because of its high genetic heterogeneity, implementation of Massively Parallel Sequencing (MPS) in diagnostic laboratories is greatly improving the possibilities of offering optimal care to patients. We present the results of a two-year period of molecular diagnosis that included 207 French families referred for non-syndromic hearing loss. Our multi-step strategy involved (i) DFNB1 locus analysis, (ii) MPS of 74 genes, and (iii) additional approaches including Copy Number Variations, in silico analyses, minigene studies coupled when appropriate with complete gene sequencing, and a specific assay for STRC. This comprehensive screening yielded an overall diagnostic rate of 48%, equally distributed between DFNB1 (24%) and the other genes (24%). Pathogenic genotypes were identified in 19 different genes, with a high prevalence of GJB2, STRC, MYO15A, OTOF, TMC1, MYO7A and USH2A. Involvement of an Usher gene was reported in 16% of the genotyped cohort. Four de novo variants were identified. This study highlights the need to develop several molecular approaches for efficient molecular diagnosis of hearing loss, as this is crucial for genetic counselling, audiological rehabilitation and the detection of syndromic forms. PMID- 29196753 TI - Mimicking Embedded Vasculature Structure for 3D Cancer on a Chip Approaches through Micromilling. AB - The ability for cells to sense and respond to microenvironmental signals is influenced by their three dimensional (3D) surroundings, which includes the extracellular matrix (ECM). In the 3D environment, vascular structures supply cells with nutrients and oxygen thus affecting cell responses such as motility. Interpretation of cell motility studies though is often restricted by the applied approaches such as 2D conventional soft lithography methods that have rectangular channel cross-sectional morphology. To better simulate cell responses to vascular supply in 3D, we developed a cell on a chip system with microfluidic channels with curved cross-sections embedded within a 3D collagen matrix that emulates anatomical vasculature more closely than inorganic polymers, thus to mimic a more physiologically relevant 3D cellular environment. To accomplish this, we constructed perfusable microfluidic channels by embedding sacrificial circular gelatin vascular templates in collagen, which were removed through temperature control. Motile breast cancer cells were pre-seeded into the collagen matrix and when presented with a controlled chemical stimulation from the artificial vasculature, they migrated towards the vasculature structure. We believe this innovative vascular 3D ECM system can be used to provide novel insights into cellular dynamics during multidirectional chemokineses and chemotaxis that exist in cancer and other diseases.

Although an additional HfO2 layer could be used to manipulate electric field on the crystal-film interface, their high absorption and polycrystalline structure were unacceptable. SiO2 was then doped in HfO2 to suppress its crystallization and to achieve low absorption by annealing. HfxSi1-xO2 nanocomposite layers were then inserted between laser crystal and SiO2 film to minimize electric-field at crystal-film interface. Laser damage resistance of this new architecture is two times higher than that of traditional zigzag slab lasers. PMID- 29196755 TI - Novel halos in light kaonic nuclei as an indicator of nuclear equation of state at supra-normal densities. AB - The sensitive correlations between the low-density halo structure and the high density properties of the nuclear equation of state (EOS) are constructed in light kaonic nuclei with the relativistic mean-field theory. More specifically, the 1p 1/2 halo spreads out linearly with increasing the pressure and sound velocity square at supra-normal densities and decreasing the incompressibility at saturation density. These results suggest that the novel halo in light kaonic nuclei can serve as a sensitive indicator of the nuclear EOS of symmetric matter at supra-normal densities. The experimental production and detection of the light kaonic nuclei, yet to be available, is discussed in some details at last.

For palaeoceanographic studies, it is important to construct a detailed and reliable chronological framework. Here, we report the results of a detailed magnetostratigraphic and rock magnetic study of four hydrogenetic Fe-Mn crusts from the Pacific Ocean (PO 01), South China Sea (SCS-01, SCS-02) and Indian Ocean (IO-01). Two groups of characteristic remanent magnetization directions were defined with nearly antipodal normal and reversed polarities for samples PO-01, SCS-01 and SCS-02, indicating a primary record of the Earth's magnetic field. The magnetostratigraphic framework, established via correlation with the Geomagnetic Polarity Time Scale 2012, implies growth rates of 4.82 mm/Ma, 4.95 mm/Ma, 4.48 mm/Ma and 11.28 mm/Ma for samples PO-01, SCS-01, SCS-02 and IO-01, respectively. Rock magnetic measurements revealed that the Fe-Mn crust samples from the Pacific Ocean and Indian Ocean were dominated by low coercivity, non-interacting, single domain (SD) magnetite particles, whereas the South China Sea samples were dominated by SD/pseudo-single-domain (PSD) particles. Multidomain (MD) magnetite may also be present in all samples.

AB - Tubulin-binding agents (TBAs) are designed to target microtubule (MT) dynamics, resulting in compromised mitotic spindles and an unsatisfied spindle assembly checkpoint. The activity of Aurora B kinase is indispensable for TBA-induced mitotic arrest, and its inhibition causes mitotic slippage and postmitotic endoreduplication. However, the precise phenomenon underlying mitotic slippage, which is caused by treatment with both Aurora B inhibitors and TBAs, and the cell fate after postmitotic slippage are not completely understood. Here, we found that HeLa and breast cancer cells treated with the different types of TBAs, such as paclitaxel and eribulin (MT-stabilizing and MT-destabilizing agents, respectively), exhibited distinct behaviors of mitotic slippage on inhibition of Aurora B. In such conditions, the cell fates after postmitotic slippage vastly differed with respect to cell morphology, cell proliferation, and cytotoxicity in short-term culture; that is, the effects of inhibition of Aurora B were beneficial for cytotoxicity enhancement in eribulin treatment but not in paclitaxel. However, in long-term culture, the cells that survived after mitotic slippage underwent endoreduplication and became giant cells in both cases, resulting in cellular senescence. We propose that MT-destabilizing agents may be more appropriate than MT-stabilizing agents for treating cancer cells with a weakened Aurora B kinase activity. PMID- 29196759 TI - Functional MRI, ERP, and psychophysical measures show that contextual effects are orientation tuned and suppressive. AB - The response of V1 neurons to a stimulus placed inside the classical receptive field can be modulated by stimuli presented outside the classical receptive field. However, the specific nature of these contextual modulations is unknown. Both enhancement and suppression have been observed as well as variability across measurement methodologies. To assess whether the contextual effect is facilitative or suppressive, we measured neural responses to an oriented Gabor stimulus ("target") in three conditions: in isolation, with two Gabor flankers that were the same orientation as the target, and with two flankers that were orthogonal to the target orientation. We show that the target-related fMRI response, event-related potential amplitude, and the amount of contrast adaptation are all lower when the flankers were the same orientation compared to both the isolated and orthogonal conditions. There was no evidence of response enhancement. These results all point to an orientation-tuned suppressive effect of contextual stimuli measured in the periphery that is well explained by models incorporating divisive or subtractive inhibition. PMID- 29196758 TI - The role of oxidative stress in the crosstalk between leptin and mineralocorticoid receptor in the cardiac fibrosis associated with obesity. AB - We have investigated whether mineralocorticoid receptor activation can participate in the profibrotic effects of leptin in cardiac myofibroblasts, as well as the potential mechanisms involved. The presence of eplerenone reduced the leptin-induced increase in protein levels of collagen I, transforming growth factor beta, connective tissue growth factor and galectin-3 and the levels of both total and mitochondrial of superoxide anion (O2.-) in cardiac myofibroblasts. Likewise, the MEK/ERK inhibitor, PD98059, and the PI3/Akt inhibitor, LY294002, showed a similar pattern. Mitochondrial reactive oxygen species (ROS) scavenger (MitoTempo) attenuated the increase in body weight observed in rats fed a high fat diet (HFD). No differences were found in cardiac function or blood pressure among any group. However, the cardiac fibrosis and enhanced O2.-levels observed in HFD rats were attenuated by MitoTempo, which also prevented the increased circulating leptin and aldosterone levels in HFD fed animals. This study supports a role of mineralocorticoid receptor in the cardiac fibrosis induced by leptin in the context of obesity and highlights the role of the mitochondrial ROS in this process. PMID- 29196760 TI - Transfer of an induced preferred retinal locus of fixation to everyday life visual tasks. AB - Subjects develop a preferred retinal locus of fixation (PRL) under simulation of central scotoma. If systematic relocations are applied to the stimulus position, PRLs manifest at a location in favor of the stimulus relocation. The present study investigates whether the induced PRL is transferred to important visual tasks in daily life, namely pursuit eye movements, signage reading, and text reading. Fifteen subjects with normal sight participated in the study. To develop a PRL, all subjects underwent a scotoma simulation in a prior study, where five subjects were trained to develop the PRL in the left hemifield, five different subjects on the right hemifield, and the remaining five subjects could naturally chose the PRL location. The position of this PRL was used as baseline. Under central scotoma simulation, subjects performed a pursuit task, a signage reading task, and a reading-text task. In addition, retention of the behavior was also studied. Results showed that the PRL position was transferred to the pursuit task and that the vertical location of the PRL was maintained on the text reading task. However, when reading signage, a function-driven change in PRL location was observed. In addition, retention of the PRL position was observed over weeks and months. These results indicate that PRL positions can be induced and may further transferred to everyday life visual tasks, without hindering function-driven changes in PRL position. PMID- 29196761 TI - Dynamic gaze-position prediction of saccadic eye movements using a Taylor series. AB - Gaze-contingent displays have been widely used in vision research and virtual reality applications. Due to data transmission, image processing, and display preparation, the time delay between the eye tracker and the monitor update may lead to a misalignment between the eye position and the image manipulation during eye movements. We propose a method to reduce the misalignment using a Taylor series to predict the saccadic eye movement. The proposed method was evaluated using two large datasets including 219,335 human saccades (collected with an EyeLink 1000 system, 95% range from 1 degrees to 32 degrees ) and 21,844 monkey saccades (collected with a scleral search coil, 95% range from 1 degrees to 9 degrees ). When assuming a 10-ms time delay, the prediction of saccade movements using the proposed method could reduce the misalignment greater than the state-of the-art methods. The average error was about 0.93 degrees for human saccades and 0.26 degrees for monkey saccades. Our results suggest that this proposed saccade prediction method will create more accurate gaze-contingent displays. PMID- 29196762 TI - Neuronal mechanisms underlying differences in spatial resolution between darks and lights in human vision. AB - Artists and astronomers noticed centuries ago that humans perceive dark features in an image differently from light ones; however, the neuronal mechanisms underlying these dark/light asymmetries remained unknown. Based on computational modeling of neuronal responses, we have previously proposed that such perceptual dark/light asymmetries originate from a luminance/response saturation within the ON retinal pathway. Consistent with this prediction, here we show that stimulus conditions that increase ON luminance/response saturation (e.g., dark backgrounds) or its effect on light stimuli (e.g., optical blur) impair the perceptual discrimination and salience of light targets more than dark targets in human vision. We also show that, in cat visual cortex, the magnitude of the ON luminance/response saturation remains relatively constant under a wide range of luminance conditions that are common indoors, and only shifts away from the lowest luminance contrasts under low mesopic light. Finally, we show that the ON luminance/response saturation affects visual salience mostly when the high spatial frequencies of the image are reduced by poor illumination or optical blur. Because both low luminance and optical blur are risk factors in myopia, our results suggest a possible neuronal mechanism linking myopia progression with the function of the ON visual pathway. PMID- 29196763 TI - Early dynamics of stereoscopic surface slant perception. AB - Surface orientation is an important visual primitive that can be estimated from monocular or binocular (stereoscopic) signals. Changes in motor planning occur within about 200 ms after either type of signal is perturbed, but the time it takes for apparent (perceived) slant to develop from stereoscopic cues is not known. Apparent slant sometimes develops very slowly (Gillam, Chambers, & Russo, 1988; van Ee & Erkelens, 1996). However, these long durations could reflect the time it takes for the visual system to resolve conflicts between slant cues that inevitably specify different slants in laboratory displays (Allison & Howard, 2000). We used a speed-accuracy tradeoff analysis to measure the time it takes to discriminate slant, allowing us to report psychometric functions as a function of response time. Observers reported which side of a slanted surface was farther, with a temporal deadline for responding that varied block-to-block. Stereoscopic slant discrimination rose above chance starting at 200 ms after stimulus onset. Unexpectedly, observers discriminated slant from binocular disparity faster than texture, and for stereoscopic whole-field stimuli faster than stereoscopic slant contrast stimuli. However, performance after the initial deviation from chance increased more rapidly for slant-contrast stimuli than whole-field stimuli. Discrimination latencies were similar for slants about the horizontal and vertical axes, but performance increased faster for slants about the vertical axis. Finally, slant from vertical disparity was somewhat slower than slant from horizontal disparity, which may reflect cue conflict. These results demonstrate, in contradiction with the previous literature, that the perception of slant from disparity happens very quickly-in fact, more quickly than the perception of slant from texture-and in comparable time to the simple perception of brightness from luminance. PMID- 29196764 TI - Differences in Trabecular Microarchitecture and Simplified Boundary Conditions Limit the Accuracy of Quantitative Computed Tomography-Based Finite Element Models of Vertebral Failure. AB - Vertebral fractures are common in the elderly, but efforts to reduce their incidence have been hampered by incomplete understanding of the failure processes that are involved. This study's goal was to elucidate failure processes in the lumbar vertebra and to assess the accuracy of quantitative computed tomography (QCT)-based finite element (FE) simulations of these processes. Following QCT scanning, spine segments (n = 27) consisting of L1 with adjacent intervertebral disks and neighboring endplates of T12 and L2 were compressed axially in a stepwise manner. A microcomputed tomography scan was performed at each loading step. The resulting time-lapse series of images was analyzed using digital volume correlation (DVC) to quantify deformations throughout the vertebral body. While some diversity among vertebrae was observed on how these deformations progressed, common features were large strains that developed progressively in the superior third and, concomitantly, in the midtransverse plane, in a manner that was associated with spatial variations in microstructural parameters such as connectivity density. Results of FE simulations corresponded qualitatively to the measured failure patterns when boundary conditions were derived from DVC displacements at the endplate. However, quantitative correspondence was often poor, particularly when boundary conditions were simplified to uniform compressive loading. These findings suggest that variations in trabecular microstructure are one cause of the differences in failure patterns among vertebrae and that both the lack of incorporation of these variations into QCT based FE models and the oversimplification of boundary conditions limit the accuracy of these models in simulating vertebral failure. PMID- 29196766 TI - Parafoveal Photoreceptor Abnormalities in Asymptomatic Patients With RP1L1 Mutations in Families With Occult Macular Dystrophy. AB - Purpose: To report the clinical characteristics of asymptomatic cases with RP1L1 gene mutations in four families with occult macular dystrophy (OMD). Methods: Four asymptomatic cases from four families were selected from a cohort of 40 subjects (16 families) with RP1L1 pathogenic variants. Clinical data of the four asymptomatic cases and three symptomatic patients in the same families were reviewed. The three asymptomatic cases did not have any visual symptoms in either eye, and one was unilaterally affected. Ophthalmologic examinations, including spectral-domain optical coherence tomography (OCT) were performed, and the morphologic characteristics of the photoreceptor layer of the asymptomatic cases were compared to those of the symptomatic patients within the same family. Results: The OCT images demonstrated photoreceptor abnormalities in the parafoveal regions in all of the four asymptomatic cases (i.e., absence of the interdigitation zone and blurring of the ellipsoid zone). However, these microstructures were preserved at the foveal center. The longitudinal reflectivity profiles clearly identified this distinct pattern in the asymptomatic cases. In contrast, no distinct abnormalities were detected by other examinations including perimetry, fundus autofluorescence images, and multifocal electroretinograms (ERGs). Conclusions: The sparing of the central foveal photoreceptor layer accounts for the well-preserved visual acuity in the asymptomatic patients. The sparing may represent either the initial phase of typical OMD or a subtype of macular lesion associated with OMD. It is necessary to examine asymptomatic subjects in families with OMD because some of them may progress to the typical phenotype of OMD. PMID- 29196765 TI - Aquaporin 0 Modulates Lens Gap Junctions in the Presence of Lens-Specific Beaded Filament Proteins. AB - Purpose: The objective of this study was to understand the molecular and physiologic mechanisms behind the lens cataract differences in Aquaporin 0 knockout-Heterozygous (AQP0-Htz) mice developed in C57 and FVB (lacks beaded filaments [BFs]) strains. Methods: Lens transparency was studied using dark field light microscopy. Water permeability (Pf) was measured in fiber cell membrane vesicles. Western blotting/immunostaining was performed to verify expression of BF proteins and connexins. Microelectrode-based intact lens intracellular impedance was measured to determine gap junction (GJ) coupling resistance. Lens intracellular hydrostatic pressure (HP) was determined using a microelectrode/manometer system. Results: Lens opacity and spherical aberration were more distinct in AQP0-Htz lenses from FVB than C57 strains. In either background, compared to wild type (WT), AQP0-Htz lenses showed decreased Pf (approximately 50%), which was restored by transgenic expression of AQP1 (TgAQP1/AQP0-Htz), but the opacities and differences between FVB and C57 persisted. Western blotting revealed no change in connexin expression levels. However, in C57 AQP0-Htz and TgAQP1/AQP0-Htz lenses, GJ coupling resistance decreased approximately 2.8-fold and the HP gradient decreased approximately 1.9 fold. Increased Pf in TgAQP1/AQP0-Htz did not alter GJ coupling resistance or HP. Conclusions: In C57 AQP0-Htz lenses, GJ coupling resistance decreased. HP reduction was smaller than the coupling resistance reduction, a reflection of an increase in fluid circulation, which is one reason for the less severe cataract in C57 than FVB. Overall, our results suggest that AQP0 modulates GJs in the presence of BF proteins to maintain lens transparency and homeostasis. PMID- 29196767 TI - The Influence of Age and Sex on Ocular Surface Microbiota in Healthy Adults. AB - Purpose: A growing body of evidence suggests that the microbiome of the ocular surface confers potent immunoregulatory functions and has a key role in the physiologic maintenance of healthy eyes and in the pathogenesis of ocular diseases. Although the microbiome is known to be affected by age and sex, the influence of these factors on ocular surface microbiota in healthy adults remains largely unknown. Methods: Ocular surface microbiome samples were obtained from the inferior bulbar conjunctiva of 48 young and 42 old adults at Zhongshan Ophthalmic Center. Using metagenomic shotgun sequencing, we characterized the sex and age-differences in conjunctival microbiome profiles of healthy adults. Results: Male and female groups differed only in the beta diversity of bacterial communities, while there were significant differences in bacterial composition, metabolic functions, and the abundance of antibiotic resistance genes between young and old adult groups. Conclusions: Our findings suggest that age and sex collectively shape the conjunctival microbiome, and may change the immune homeostasis of the ocular surface through alterations of its commensal microbiome. PMID- 29196769 TI - CTG18.1 Expansion in TCF4 Among African Americans With Fuchs' Corneal Dystrophy. AB - Purpose: Studies of Fuchs' dystrophy have largely focused on individuals of European origin. Characterization of disease among African Americans is required to ensure prognostic factors and therapeutic approaches are applicable across diverse patient populations. Methods: We assessed all self-reported black and white patients aged older than 40 years at a tertiary care institution with a diagnosis of cataract over a 3-year period for concurrent diagnosis of Fuchs' dystrophy. Affected patients in a longitudinal cohort were invited to provide a blood sample from which we extracted genomic DNA. The CTG18.1 trinucleotide repeat length was determined using a two-step, triplet repeat primed PCR protocol. Expansion was defined as >40 CTG repeats. Demographic information, including race, was documented. Results: Of 59,365 self-reported black and white adults who presented for cataract evaluation, the odds ratio of presenting with Fuchs' dystrophy among black compared to white patients was 0.6992 (95% confidence interval [CI], 0.6210-0.7872). A total of 60 black and 549 white patients with Fuchs' corneal dystrophy enrolled in the longitudinal study, of which 21 (35.0%) black and 343 (62.5%) white patients demonstrated trinucleotide repeat expansion, a significant difference (P = 7.7 * 10-5). In a multivariable linear regression model, repeat expansion but not race was significantly associated with mean clinical grading of severity. Conclusions: Black patients with Fuchs' dystrophy were less likely than white patients to demonstrate CTG18.1 allele expansion. The data contribute to our understanding of population differences in clinical presentation, and highlight the need for considering diversity of patient populations in clinical research. PMID- 29196768 TI - Macular Atrophy Development and Subretinal Drusenoid Deposits in Anti-Vascular Endothelial Growth Factor Treated Age-Related Macular Degeneration. AB - Purpose: To explore the association between presence of subretinal drusenoid deposits (SDD) at baseline in eyes with neovascular age-related macular degeneration (nAMD) with the development of macular atrophy (MA) during anti vascular endothelial growth factor (VEGF) therapy. Methods: There were 74 eyes without pre-existing MA receiving anti-VEGF therapy for nAMD for 2 years or longer analyzed. At least two image modalities that included spectral-domain optical coherence tomography, near-infrared reflectance, fluorescein angiography, and color fundus photos were used to assess for SDD presence, phenotype (dot and ribbon), and location, neovascularization type, and MA. Logistic regression models using generalized estimating equations assessed the association between SDD and the development of MA adjusting for age, neovascularization type, and choroidal thickness. Results: SDD were present in 46 eyes (63%) at baseline. MA developed in 38 eyes (51%) during the mean of 4.7 +/- 1.2 years of follow-up. Compared with eyes without SDD, those with SDD at baseline were 3.0 times (95% confidence interval [CI] 1.1-8.5, P = 0.0343) more likely to develop MA. Eyes with SDD present in the inferior macula and inferior extramacular fields at baseline were 3.0 times and 6.5 times more likely to develop MA at follow-up than eyes without SDD in these locations (95% CI 1.0-8.9, P = 0.0461 and 95% CI 1.3 32.4, P = 0.0218, respectively). MA development was not associated with a specific SDD phenotype. Conclusions: MA frequently developed in eyes during anti VEGF treatment. SDD were independently associated with MA development. The extension of SDD into the inferior fundus, particularly in the inferior extramacular field, conferred higher odds of subsequent MA development. PMID- 29196770 TI - Effect of Gravity Acceleration on Choroidal and Retinal Nerve Fiber Layer Thickness: A Swept-Source Optical Coherence Tomography Study. AB - Purpose: The purpose of this study was to evaluate the effect of gravity acceleration on choroidal and retinal nerve fiber layer (RNFL) thickness using swept-source optical coherence tomography (SS-OCT). Methods: Thirteen healthy volunteers who planned to participate in human centrifuge training as part of the flight surgeon selection process enrolled this study. During centrifuge training, gravity was gradually increased up to six times that of sea level. All subjects underwent complete ophthalmologic examination and three-dimensional wide-scanning SS-OCT imaging (DRI OCT-1 Atlantis; Topcon, Tokyo, Japan). Imaging was performed before (baseline), immediately after, and 15, 30, and 60 minutes after centrifuge training. Changes in choroidal thickness, choroidal volume, retinal thickness, and RNFL thickness after centrifuge training were analyzed. Results: Mean choroidal thickness significantly and transiently decreased immediately (258.19 +/- 73.54 MUm, P < 0.001), 15 minutes (258.54 +/- 75.12 MUm, P = 0.001), and 30 minutes (254.31 +/- 66.92, P = 0.001) after human centrifuge training, relative to baseline (273.35 +/- 80.80 MUm). However, the decreased choroidal thickness returned to baseline levels 1 hour after centrifuge training (270.12 +/- 71.69 MUm, P = 0.437). Mean retinal thickness and RNFL thickness were not significantly affected by human centrifuge training. In participants who suffered from gravity force induced loss of consciousness (G-LOC) during training, the amount of the choroidal thickness decrease was larger than in participants who did not experience G-LOC. However, because of the small sample size, the difference, although large, was not statistically significant. Conclusions: Choroidal thickness and volume significantly and transiently decreased after human centrifuge training, which might reflect that choroidal perfusion was transiently decreased during human centrifuge training. Considering choroidal thickness decreased after human centrifuge training, long-term exposure to a high gravity environment may lead to ischemic injury to ocular structures. PMID- 29196772 TI - Correlation of cue-locked FRN and feedback-locked FRN in the auditory monetary incentive delay task. AB - Reflecting the discrepancy between received and predicted outcomes, the reward prediction error (RPE) plays an important role in learning in a dynamic environment. A number of studies suggested that the feedback-related negativity (FRN) component of an event-related potential, known to be associated with unexpected outcomes, encodes RPEs. While FRN was clearly shown to be sensitive to the probability of outcomes, the effect of outcome magnitude on FRN remains to be further clarified. In studies on the neural underpinnings of reward anticipation and outcome evaluation, a monetary incentive delay (MID) task proved to be particularly useful. We investigated whether feedback-locked FRN and cue-locked dN200 responses recorded during an auditory MID task were sensitive to the probability and magnitude of outcomes. The cue-locked dN200 is associated with the update of information about the magnitude of prospective outcomes. Overall, we showed that feedback-locked FRN was modulated by both the magnitude and the probability of outcomes during an auditory version of MID task, whereas no such effect was found for cue-locked dN200. Furthermore, the cue-locked dN200, which is associated with the update of information about the magnitude of prospective outcomes, correlated with the standard feedback-locked FRN, which is associated with a negative RPE. These results further expand our knowledge on the interplay between the processing of predictive cues that forecast future outcomes and the subsequent revision of these predictions during outcome delivery. PMID- 29196773 TI - Effects of contact-based mental illness stigma reduction programs: age, gender, and Asian, Latino, and White American differences. AB - PURPOSE: Mental illness stigma disproportionately affects help seeking among youth, men, and ethnic minorities. As part of a comprehensive statewide initiative to reduce mental illness stigma and discrimination in California, a broad set of contact-based educational programs were widely disseminated. This study examined whether the effects of contact-based educational programs varied depending on the age, gender, and race-ethnicity of participants. METHODS: Participants (N = 4122) attended a contact-based educational program that was delivered as part of the statewide initiative to reduce mental illness stigma and discrimination. Self-administered surveys assessing beliefs, attitudes, and intentions toward mental illnesses and treatment were conducted immediately before and after participation in contact-based educational programs. RESULTS: Participant age, gender, and race-ethnicity significantly moderated pre-post changes in mental illness stigma. Although all groups exhibited significant pre post changes across most of the stigma domains assessed, young adults, females, and Asian and Latino American participants reported larger improvements compared to older adults, males, and Whites, respectively. CONCLUSIONS: Findings suggest that contact-based educational programs can achieve immediate reductions in mental illness stigma across a variety of sociodemographic groups and may particularly benefit young adults and racial-ethnic minorities. Further research is needed to assess whether contact-based educational programs can sustain longer term changes and aid in the reduction of disparities in mental illness stigma and treatment. PMID- 29196771 TI - The interrelation of osteoarthritis and diabetes mellitus: considering the potential role of interleukin-10 and in vitro models for further analysis. AB - INTRODUCTION: Today, not only the existence of an interrelation between obesity/adipositas and osteoarthritis (OA) but also the association of OA and diabetes mellitus (DM) are widely recognized. Nevertheless, shared influence factors facilitating OA development in DM patients still remain speculative up until now. To supplement the analysis of clinical data, appropriate in vitro models could help to identify shared pathogenetic pathways. Informative in vitro studies could later be complemented by in vivo data obtained from suitable animal models. MATERIALS AND METHODS: Therefore, this detailed review of available literature was undertaken to discuss and compare the results of currently published in vitro studies focusing on the interrelation between OA, the metabolic syndrome and DM and to propose models to further study the molecular pathways. RESULTS: The survey of literature presented here supports the hypothesis that the pathogenesis of OA in DM is based on imbalanced molecular pathways with a putative crucial role of antiinflammatory cytokines such as IL 10. CONCLUSION: Future development of versatile micro-scaled in vitro models such as combining DM and OA on chip could allow the identification of common pathogenetic pathways and might help to develop novel therapeutic strategies. PMID- 29196774 TI - [Suitability of computer-assisted femoral intramedullary nailing for control of torsion and length : Systematic review of clinical studies]. AB - BACKGROUND: Despite promising results in experimental studies, computer-assisted femoral intramedullary nailing has not become established in the clinical practice for most orthopedic surgeons. The purpose of this study was to evaluate the advantages and disadvantages of computer-assisted reduction and nailing of femoral fractures as reported in clinical studies. MATERIAL AND METHODS: A systematic analysis of the available literature on the clinical application of computer-assisted femoral intramedullary nailing (Pubmed, Cochrane library and Embase) was carried out. Studies published up to May 2017 were included. RESULTS: A total of three articles were included in this meta-analysis. All studies showed a relevant increase in total operating time and radiation exposure time with the use of computer-assisted femoral intramedullary nailing. The clinical results for computer-assisted nailing with respect to femoral torsion and length tended to be slightly better but the results were very heterogeneous. CONCLUSION: Our analysis could show that computer-assisted femoral intramedullary nailing is clinically feasible but the operative and fluoroscopy time needed are high and the reported postoperative results for femoral length and torsion were very heterogeneous. Further comparative studies are needed in the future. PMID- 29196775 TI - A health economic simulation model for the clinical management of osteoporosis. AB - : The objective was to estimate the burden of osteoporosis in Sweden based on current clinical practice and the cost-effectiveness of improvements in the management of osteoporosis over the clinical management compared to current clinical practice. Results showed that better compliance to treatment guidelines is associated with better projected outcomes and cost-savings. INTRODUCTION: The purpose of this study is to estimate the burden of osteoporosis in Sweden based on current clinical practice and the cost-effectiveness of improvements in the management of osteoporosis over the clinical management compared to current clinical practice. METHODS: The analysis was carried out using a model that simulates the individual patients considered for pharmacological treatment during 1 year and their projected osteoporosis treatment pathway, quality-adjusted life years (QALYs) and costs over their remaining lifetime. All patients regardless of treatment or no treatment were simulated. Information on current management of osteoporosis in terms of patient characteristics and treatment patterns were derived from a Swedish osteoporosis research database based on national registers and patient records. Current (standard) clinical management was compared with alternative scenarios mirroring Swedish treatment guidelines. RESULTS: The national burden in terms of lost QALYs was estimated at 14,993 QALYs and the total economic cost at ?776M. Scenario analyses showed that 382-3864 QALYs could be gained at a cost/QALY ranging from cost-saving to ?31368, depending on the scenario. The margin of investment, i.e. the maximum amount that could be invested in the healthcare system to achieve these improvements up to the limit of the willingness to pay/QALY, was estimated at ?199M on a population level (?3,634/patient). CONCLUSIONS: The analysis showed that better compliance to treatment guidelines is associated with better projected outcomes and cost savings. From a cost-effectiveness perspective, there is also considerable room for investment to achieve these improvements in the management of osteoporosis.

AB - Rosellinia necatrix: causing root rot disease is a very destructive pathogen of woody plants and is responsible for yield losses to a large number of fruit trees. The genetic analysis of this pathogen has not been picked up because of difficulty in generating mutations in Rosellinia necatrix for many reasons. A number of methods have been proposed for inducing mutations in Rosellinia necatrix but none of them proved worth because of very low transformation efficiencies. Here, we propose an efficient method for Rosellinia necatrix protoplast production, where protoplasts in the tune of 107 per ml can be easily generated. We also propose a restriction enzyme-mediated integration (REMI)-based methods for efficient transformation of Rosellinia necatrix. In the present study, an approximate of 800 transformants was obtained from 5 MUg of linearized plasmid. Out of 47 single spored transformants analyzed, only 33 showed hygromycin gene amplification using PCR and only 19 transformants showed single gene integration in southern hybridization, which accounted for single gene integration percentage of 42%, highest amongst all the previous reports on Rosellinia necatrix transformations. Some of the transformants studied for pathogenicity phenotype also showed a marked reduction in pathogenicity. Thus, in the present investigation, 42% single gene integrations among the transformed colonies can be considered as excellent transformation efficiency.

PMID- 29196781 TI - Acute Pulmonary Vasodilator Testing and Long-Term Clinical Course in Segmental Pulmonary Vascular Disease. AB - Results of acute pulmonary vasodilator testing (AVT) and the outcome of medical therapy have not been described in patients with segmental pulmonary vascular disease (SPVD). We sought to compare the pulmonary vasodilatory effects of oxygen, oxygen with nitric oxide, and diltiazem, and to describe the clinical course of patients with SPVD and pulmonary hypertension. A retrospective review of 16 patients with pulmonary hypertension and SPVD involving 2-3 major lung segments who underwent AVT between January 2000 and December 2015 was performed. Baseline hemodynamic measurements were obtained with patients breathing <= 30% oxygen. AVT was performed using 100% oxygen, 100% oxygen with 20 ppm nitric oxide, 21-35% oxygen, and 21-35% oxygen with intravenous diltiazem. The events associated with their long-term care were described. Nine of 16 patients were acutely responsive during AVT using the Sitbon criteria. The change in mean pulmonary artery pressure with oxygen or oxygen with nitric oxide (19 +/- 12 mmHg) was significantly greater than the change with diltiazem (7 +/- 5 mmHg). Pulmonary vasodilator therapy was initiated or escalated after AVT in 12 patients. Five patients subsequently experienced a decrease in mean pulmonary artery pressure or normalization in B-type natriuretic peptide. Three patients experienced adverse events associated with therapy. The actuarial survival was 94% over a period of 1-20 years. This study suggests that AVT can be used to identify patients with SPVD who are reactive to oxygen, oxygen with nitric oxide, and diltiazem. Clinical improvement was temporally associated with pulmonary vasodilator therapy in some patients with few adverse effects.

AB - AIMS/HYPOTHESIS: The aim of this study was to quantify the relative contributions of increased insulin secretion rate (ISR) and decreased insulin clearance rate (ICR) in the compensatory hyperinsulinaemia characteristic of insulin-resistant individuals without diabetes. METHODS: Obese (BMI >=30 kg/m2) individuals without diabetes (n = 91) were identified from a registry of volunteers. Volunteers underwent the following measurements: oral glucose tolerance; insulin resistance (steady-state plasma glucose [SSPG] concentration during the insulin suppression test [IST]); ISR (using the graded glucose infusion test [GGIT]); and ICR (using the IST and GGIT). Participants were stratified into tertiles based on SSPG concentration: SSPG-1(insulin-sensitive); SSPG-2 (intermediate); and SSPG-3 (insulin-resistant). RESULTS: There were no differences in BMI and waist circumference among the SSPG tertiles. Serum alanine aminotransferase concentrations were higher in the SSPG-2 and SSPG-3 groups compared with the SSPG 1 group (p = 0.02). Following an oral glucose challenge, there was a progressive increase in the total integrated insulin response from the most insulin-sensitive to the most insulin-resistant tertiles (p < 0.001). Following intravenous glucose, the SSPG-3 group had significantly greater integrated glucose (median [interquartile range], 32.9 [30.8-36.3] mmol/l * h) and insulin responses (1711 [1476-2223] mmol/l * h) compared with the SSPG-1 group (30.3 [28.8-32.9] mmol/l * h, p = 0.04, and 851 [600-1057] pmol/l * h, p < 0.001, respectively). Furthermore, only the SSPG-3 group had significant changes in both ISR and ICR (p < 0.001). In the SSPG-2 group, only the ICR was significantly decreased compared with the SSPG-1 group. Therefore, ICR progressively declined during the IST with increasing insulin resistance (SSPG-1, 0.48 [0.41-0.59]; SSPG-2, 0.43 [0.39 0.50]; SSPG-3, 0.34 [0.31-0.40]). CONCLUSIONS/INTERPRETATION: While both increases in ISR and decreases in ICR compensate for insulin resistance, decreases in ICR may provide the first adaptation to decreased insulin sensitivity. PMID- 29196783 TI - Combinatorial detection of autoreactive CD8+ T cells with HLA-A2 multimers: a multi-centre study by the Immunology of Diabetes Society T Cell Workshop. AB - AIMS/HYPOTHESIS: Validated biomarkers are needed to monitor the effects of immune intervention in individuals with type 1 diabetes. Despite their importance, few options exist for monitoring antigen-specific T cells. Previous reports described a combinatorial approach that enables the simultaneous detection and quantification of multiple islet-specific CD8+ T cell populations. Here, we set out to evaluate the performance of a combinatorial HLA-A2 multimer assay in a multi-centre setting. METHODS: The combinatorial HLA-A2 multimer assay was applied in five participating centres using centralised reagents and blinded replicate samples. In preliminary experiments, samples from healthy donors were analysed using recall antigen multimers. In subsequent experiments, samples from healthy donors and individuals with type 1 diabetes were analysed using beta cell antigen and recall antigen multimers. RESULTS: The combinatorial assay was successfully implemented in each participating centre, with CVs between replicate samples that indicated good reproducibility for viral epitopes (mean %CV = 33.8). For beta cell epitopes, the assay was very effective in a single-centre setting (mean %CV = 18.4), but showed sixfold greater variability across multi-centre replicates (mean %CV = 119). In general, beta cell antigen-specific CD8+ T cells were detected more commonly in individuals with type 1 diabetes than in healthy donors. Furthermore, CD8+ T cells recognising HLA-A2-restricted insulin and glutamate decarboxylase epitopes were found to occur at higher frequencies in individuals with type 1 diabetes than in healthy donors. CONCLUSIONS/INTERPRETATION: Our results suggest that, although combinatorial multimer assays are challenging, they can be implemented in multiple laboratories, providing relevant T cell frequency measurements. Assay reproducibility was notably higher in the single-centre setting, suggesting that biomarker analysis of clinical trial samples would be most successful when assays are performed in a single laboratory. Technical improvements, including further standardisation of cytometry platforms, will likely be necessary to reduce assay variability in the multi-centre setting. PMID- 29196784 TI - PARP1 protects from benzo[a]pyrene diol epoxide-induced replication stress and mutagenicity. AB - Poly(ADP-ribosyl)ation (PARylation) is a complex and reversible posttranslational modification catalyzed by poly(ADP-ribose)polymerases (PARPs), which orchestrates protein function and subcellular localization. The function of PARP1 in genotoxic stress response upon induction of oxidative DNA lesions and strand breaks is firmly established, but its role in the response to chemical-induced, bulky DNA adducts is understood incompletely. To address the role of PARP1 in the response to bulky DNA adducts, we treated human cancer cells with benzo[a]pyrene 7,8 dihydrodiol-9,10-epoxide (BPDE), which represents the active metabolite of the environmental carcinogen benzo[a]pyrene [B(a)P], in nanomolar to low micromolar concentrations. Using a highly sensitive LC-MS/MS method, we revealed that BPDE induces cellular PAR formation in a time- and dose-dependent manner. Consistently, PARP1 activity significantly contributed to BPDE-induced genotoxic stress response. On one hand, PARP1 ablation rescued BPDE-induced NAD+ depletion and protected cells from BPDE-induced short-term toxicity. On the other hand, strong sensitization effects of PARP inhibition and PARP1 ablation were observed in long-term clonogenic survival assays. Furthermore, PARP1 ablation significantly affected BPDE-induced S- and G2-phase transitions. Together, these results point towards unresolved BPDE-DNA lesions triggering replicative stress. In line with this, BPDE exposure resulted in enhanced formation and persistence of DNA double-strand breaks in PARP1-deficient cells as evaluated by microscopic co-localization studies of 53BP1 and gammaH2A.X foci. Consistently, an HPRT mutation assay revealed that PARP inhibition potentiated the mutagenicity of BPDE. In conclusion, this study demonstrates a profound role of PARylation in BPDE-induced genotoxic stress response with significant functional consequences and potential relevance with regard to B[a]P-induced cancer risks. PMID- 29196785 TI - Improvement in physician pain perception with using pain scales. AB - BACKGROUND AND AIMS: Acute pain is the most common reason for visits to the emergency department (ED). The underuse of analgesics occurs in a large proportion of ED patients. The physician's accurate assessment of patients' pain is a key element to improved pain management. The purpose of this study was to assess if physicians' perception of pain can improve with looking at the pain score of the patient marked on VAS. STUDY DESIGN: This was a single-center, cross sectional prospective observational study, that took place in an academic ED. METHODS: All adult ED patients presenting with a painful condition were enrolled to the study. In the first phase of the study, the physician rated his/her opinion about the patient's pain on a 100 mm VAS, in a blinded fashion to the patient's pain score. In the second phase, the physician rated his/her opinion after looking at the pain scale marked by patient. RESULTS: 587 patients (295, in first and 292, in second phase) were enrolled. The groups were not statistically different for demographic data. The physician's perception of pain was lower than the patient's pain score at both phases of the study. Insight of the patient's pain score on VAS increased the physician's pain perception significantly (p = 0.03). During the second phase, physicians ordered significantly more analgesic medications to the patients (p = 0.03). CONCLUSION: The physicians' perception of the patients' pain differs significantly from the pain that the patient is experiencing. VAS helps to bring the physicians impression of pain perception to the level of pain that the patient is actually experiencing and resulted in ordering more analgesics to the patients. Implementation of a pain assessment tool can raise the physician's perception of the pain and may improve pain management practices and patient satisfaction. PMID- 29196786 TI - Increased heterologous production of the antitumoral polyketide mithramycin A by engineered Streptomyces lividans TK24 strains. AB - Mithramycin A is an antitumor compound used for treatment of several types of cancer including chronic and acute myeloid leukemia, testicular carcinoma, hypercalcemia and Paget's disease. Selective modifications of this molecule by combinatorial biosynthesis and biocatalysis opened the possibility to produce mithramycin analogues with improved properties that are currently under preclinical development. The mithramycin A biosynthetic gene cluster from Streptomyces argillaceus ATCC12956 was cloned by transformation assisted recombination in Saccharomyces cerevisiae and heterologous expression in Streptomyces lividans TK24 was evaluated. Mithramycin A was efficiently produced by S. lividans TK24 under standard fermentation conditions. To improve the yield of heterologously produced mithramycin A, a collection of derivative strains of S. lividans TK24 were constructed by sequential deletion of known potentially interfering secondary metabolite gene clusters using a protocol based on the positive selection of double crossover events with blue pigment indigoidine producing gene. Mithramycin A production was evaluated in these S. lividans strains and substantially improved mithramycin A production was observed depending on the deleted gene clusters. A collection of S. lividans strains suitable for heterologous expression of actinomycetes secondary metabolites were generated and efficient production of mithramycin A with yields close to 3 g/L, under the tested fermentation conditions was achieved using these optimized collection of strains. PMID- 29196787 TI - Erythritol as sweetener-wherefrom and whereto? AB - Erythritol is a naturally abundant sweetener gaining more and more importance especially within the food industry. It is widely used as sweetener in calorie reduced food, candies, or bakery products. In research focusing on sugar alternatives, erythritol is a key issue due to its, compared to other polyols, challenging production. It cannot be chemically synthesized in a commercially worthwhile way resulting in a switch to biotechnological production. In this area, research efforts have been made to improve concentration, productivity, and yield. This mini review will give an overview on the attempts to improve erythritol production as well as their development over time. PMID- 29196788 TI - Quantification of the catalytic performance of C1-cellulose-specific lytic polysaccharide monooxygenases. AB - Lytic polysaccharide monooxygenases (LPMOs) have recently been shown to significantly enhance the degradation of recalcitrant polysaccharides and are of interest for the production of biochemicals and bioethanol from plant biomass. The copper-containing LPMOs utilize electrons, provided by reducing agents, to oxidatively cleave polysaccharides. Here, we report the development of a beta glucosidase-assisted method to quantify the release of C1-oxidized gluco oligosaccharides from cellulose by two C1-oxidizing LPMOs from Myceliophthora thermophila C1. Based on this quantification method, we demonstrate that the catalytic performance of both MtLPMOs is strongly dependent on pH and temperature. The obtained results indicate that the catalytic performance of LPMOs depends on the interaction of multiple factors, which are affected by both pH and temperature. PMID- 29196789 TI - Prediction of functional recovery after primary PCI using the estimate of myocardial salvage in gated SPECT early after acute myocardial infarction. AB - PURPOSE: Primary percutaneous coronary intervention (PCI) in acute myocardial infarction (AMI) aims to achieve myocardial salvage (MS). Because the reference method for measuring MS requires myocardial perfusion imaging (MPI) after tracer injection before PCI, alternative approaches have been proposed, but none has gained wide acceptance. Gated SPECT MPI can assess infarct size (IS), but can also show myocardial stunning. Thus, we compared functional and perfusion abnormalities early after AMI to estimate MS, and to predict left ventricular ejection fraction (LVEF) recovery at follow-up. METHODS: We studied 120 patients with AMI. Gated SPECT MPI was performed early (before hospital discharge) and at 6 months after AMI to measure IS, MS and functional outcome. MS was defined as the difference between the number of segments with abnormal thickening (i.e. the stunned area or area at risk) and the number of segments with abnormal perfusion (i.e. the final IS), expressed as a percentage of the total number of segments in the AHA model. LVEF was calculated using quantitative gated SPECT. RESULTS: The area at risk was 40 +/- 25%, IS was 17.3 +/- 16% and MS was 22 +/- 19%. Early LVEF was 46.6 +/- 11.6% and late LVEF was 51.4 +/- 11.6%, with 54 patients showing at least an increase in LVEF of more than 5 units. ROC analysis showed that MS was able to predict LVEF recovery with an area under the curve (AUC) of 0.79 (p < 0.0001), and using a cut off >23% detected LVEF recovery with 74% sensitivity and 71% specificity. Conversely, IS was associated with an AUC 0.53 (not significant). CONCLUSION: MS assessed by a single early gated SPECT MPI study can accurately predict LVEF evolution after primary PCI for AMI.

PMID- 29196791 TI - Comparison of dual mobility cup and other surgical construts used for three hundred and sixty two first time hip revisions due to recurrent dislocations: five year results from Lithuanian arthroplasty register. AB - PURPOSE: Recently, there has been increasing interest in the use of dual mobility systems in the treatment of hip instability. The aim of this study was to investigate the re-revision rate of dual mobility cup compared to different surgical concepts when used for first-time hip revisions due to recurrent dislocations. METHODS: The data were derived from the Lithuanian Arthroplasty Register. For survival analysis, we used both re-revision for all reasons and for dislocations as an end-point. Cox proportional hazards models were used to analyze the influence of various covariates (age, gender, and implant concept). RESULTS: A total of 1388 revisions were recorded from 2011 to 2015, of which 362 were performed due to recurrent dislocation. Of the revisions, 247 were performed using dual mobility cups, while 115 were performed using a variety of other surgical constructs including constrained acetabular cups, conventional cups, femoral head exchanges, stem exchanges or anti-luxation rings. There were 27 re revisions of which 15 were for additional dislocations. There were only 2% re revisions due to dislocation with dual mobility vs 9% when using other surgical constructs. Cox regression adjusting for age and gender showed that in the short term, dual mobility cup had a lower risk of revision due to dislocation as well as for all reasons compared to the other surgical constructs. CONCLUSION: In revision of total hip arthroplasties for dislocation, significantly lower short term re-revision rate was observed for patients revised with dual mobility cup.

AB - Phytoremediation of nutrients and pesticides in runoff is a growing conservation effort, particularly in agriculturally intensive areas such as the lower Mississippi River Valley. In the current study, rice (Oryza sativa) was examined for its mitigation capacity of nitrogen, phosphorus, diazinon, and permethrin. Twenty-two high density polyethylene circular containers (56 cm x 45 cm) were used as mesocosms, with 12 mesocosms planted with rice and 10 mesocosms remaining unvegetated. Mesocosms were hydraulically connected and arranged in a series of two, with each system providing a 4 h hydraulic retention time (HRT) for a total system retention time of 8 h. Two treatments (RICE/RICE and RICE/BARE) of four replicates each were utilized, with three replicates of controls (BARE/BARE). Systems with RICE/RICE (8 h HRT) significantly reduced diazinon (p = 0.0126), cis permethrin (p = 0.0442), filtered orthophosphate (p = 0.0058), and total orthophosphate (p = 0.0123) compared to control systems. No significant differences were noted for trans-permethrin, nitrate, or ammonium. Results indicate promise in phytoremediation of agricultural runoff by rice. If further studies reveal contaminants are not transferred into seeds, then rice could potentially serve as both a remediation tool and food source in countries facing agricultural pollution challenges. PMID- 29196794 TI - Ultrasound-guided or landmark techniques for central venous catheter placement in critically ill children. AB - PURPOSE: To assess whether ultrasound guidance improves central venous catheter placement outcomes compared to the landmark technique in critically ill children. METHODS: A prospective multicentre observational study was carried out in 26 paediatric intensive care units over 6 months. Children 0-18 years old who received a temporary central venous catheter, inserted using either ultrasound or landmark techniques, were eligible. The primary outcome was the first-attempt success rate. Secondary outcomes included overall placement success, number of puncture attempts, number of procedures requiring multiple punctures (> 3 punctures), number of procedures requiring punctures at more than one vein site and immediate mechanical complications. To account for potential confounding factors, we used propensity scores. Our primary analysis was based on 1:1 propensity score matching. The association between cannulation technique and outcomes in the matched cohort was estimated using generalized estimating equations and mixed-effects models to account for patient-level and hospital level confounders. RESULTS: Five hundred central venous catheter-placement procedures involving 354 patients were included. Ultrasound was used for 323 procedures, and the landmark technique was used for 177. Two hundred and sixty six procedures were matched (133 in the ultrasound group and 133 in the landmark group). Ultrasound was associated with an increase in the first-attempt success rate [46.6 vs. 30%, odds ratio 2.09 (1.26-3.46); p < 0.001], a reduced number of puncture attempts [2 (1-3) vs. 2 (1-4), B coefficient - 0.51 (95% confidence interval - 1.01 to - 0.03), p = 0.035], and fewer overall mechanical complications [12 vs. 22.5%, odds ratio 0.47 (95% confidence interval 0.24-0.91), p = 0.025] in the matched cohort. The number of puncture attempts was the main factor associated with overall complications. CONCLUSIONS: Compared with the landmark technique, ultrasound guidance was associated with an increased first attempt success rate, a reduced number of puncture attempts, and fewer complications during central venous catheter placement in critically ill children.

PMID- 29196796 TI - Increased herpes zoster risk associated with poor HLA-A immediate early 62 protein (IE62) affinity. AB - Around 30% of individuals will develop herpes zoster (HZ), caused by the varicella zoster virus (VZV), during their life. While several risk factors for HZ, such as immunosuppressive therapy, are well known, the genetic and molecular components that determine the risk of otherwise healthy individuals to develop HZ are still poorly understood. We created a computational model for the Human Leukocyte Antigen (HLA-A, -B, and -C) presentation capacity of peptides derived from the VZV Immediate Early 62 (IE62) protein. This model could then be applied to a HZ cohort with known HLA molecules. We found that HLA-A molecules with poor VZV IE62 presentation capabilities were more common in a cohort of 50 individuals with a history of HZ compared to a nationwide control group, which equated to a HZ risk increase of 60%. This tendency was most pronounced for cases of HZ at a young age, where other risk factors are less prevalent. These findings provide new molecular insights into the development of HZ and reveal a genetic predisposition in those individuals most at risk to develop HZ.

PMID- 29196797 TI - Sorting nexin 3 mutation impairs development and neuronal function in Caenorhabditis elegans. AB - The sorting nexins family of proteins (SNXs) plays pleiotropic functions in protein trafficking and intracellular signaling and has been associated with several disorders, namely Alzheimer's disease and Down's syndrome. Despite the growing association of SNXs with neurodegeneration, not much is known about their function in the nervous system. The aim of this work was to use the nematode Caenorhabditis elegans that encodes in its genome eight SNXs orthologs, to dissect the role of distinct SNXs, particularly in the nervous system. By screening the C. elegans SNXs deletion mutants for morphological, developmental and behavioral alterations, we show here that snx-3 gene mutation leads to an array of developmental defects, such as delayed hatching, decreased brood size and life span and reduced body length. Additionally, ?snx-3 worms present increased susceptibility to osmotic, thermo and oxidative stress and distinct behavioral deficits, namely, a chemotaxis defect which is independent of the described snx-3 role in Wnt secretion. ?snx-3 animals also display abnormal GABAergic neuronal architecture and wiring and altered AIY interneuron structure. Pan-neuronal expression of C. elegans snx-3 cDNA in the ?snx-3 mutant is able to rescue its locomotion defects, as well as its chemotaxis toward isoamyl alcohol. Altogether, the present work provides the first in vivo evidence of the SNX-3 role in the nervous system. PMID- 29196799 TI - 3C-PCR: a novel proximity ligation-based approach to phase chromosomal rearrangement breakpoints with distal allelic variants. AB - Recent advances in molecular cytogenetics highlight the importance of noncoding structural variation in human disease. Genomic rearrangements can disrupt chromatin architecture, leading to long-range alterations in gene expression. With increasing ability to assess distal gene dysregulation comes new challenges in clinical interpretation of rearrangements. While haplotyping methods to determine compound heterozygosity in a single gene with two pathogenic variants are established, such methods are insufficient for phasing larger distances between a pathogenic variant and a genomic rearrangement breakpoint. Herein, we present an inexpensive and efficient proximity ligation-based method called 3C PCR for phasing chromosomal rearrangement breakpoints with distal allelic variants. 3C-PCR uses canonical chromosome conformation capture (3C) libraries for targeted distal phasing by implementing a novel nested PCR strategy with primers anchored across the rearrangement breakpoints and subsequent Sanger sequencing. As a proof of concept, 3C-PCR was used to phase a highly variable region 1.3 Mb upstream of a chromosomal rearrangement breakpoint in a balanced translocation. We found that the nested PCR approach amplified the derivative chromosome substrate exclusively and identified the same haplotype by Sanger sequencing reliably. Given its efficacy and versatility, 3C-PCR is ideal for use in phasing chromosomal rearrangement breakpoints with allelic variants located at a genomic distance over a megabase. PMID- 29196800 TI - Effects of mating on host selection by female small white butterflies Pieris rapae (Lepidoptera: Pieridae). AB - Mating might significantly affect the host selection behaviors of phytophagous insects. Here, we investigated the post-mating changes in behavioral and antennal responses of Pieris rapae (Lepidoptera: Pieridae) females to host plant volatiles. In two-choice bioassays using artificial plant models, mated females visited the model scented with synthetic blends (15-, 9-, or 6-components) of cabbage plant volatiles more frequently than the unscented control, whereas virgin females did not exhibit this preference. Because single compounds and the 3-component blend did not induce preferential visiting, mated females apparently utilized complex odor blends as their host-finding cue. Moreover, 2- to 4-day-old mated females visited the models, scented and unscented, more frequently than did their virgin counterparts. Therefore, mating enhanced the host-finding behavior of young females and their responsiveness to plant volatiles. Gas chromatography electroantennographic detector analysis revealed that eight of the 15 compounds in the cabbage plant volatiles elicited responses from female antennae. However, post-mating and age-dependent changes in antennal responses were not detected. Because female peripheral (antennal) sensitivity to volatiles remained practically unchanged after emergence, post-mating changes in host selection might be attributed to changes in the central nervous system.

PMID- 29196802 TI - Study of serial serum myeloid-related protein 8/14 as a sensitive biomarker in Takayasu arteritis: a single centre study. AB - The aim of the study was to explore utility of serial serum myeloid-related protein 8/14 (MRP8/14) as a biomarker of clinical disease activity and angiographic progression in Takayasu arteritis (TA). Serum MRP8/14 levels were assayed by commercial ELISA for 85 TA patients and 24 healthy controls at baseline, and for 56 and 21 TA patients during follow-up visits R1 and R2, respectively. Disease was categorised as active, indeterminate and stable according to Indian Takayasu Arteritis score (ITAS 2010), ITAS-A(CRP) and angiography. Patients were divided into responders and non-responders/relapsers based on treatment response. Non-parametric tests were used for inter-group comparisons at baseline and during follow-up time points. Generalised Estimating Equation was used to study association between changes in serial MRP8/14 levels and disease activity. At baseline, median MRP8/14 levels were higher in patients with TA than healthy controls [7353 (4524 to11283) vs 4896 (3194 to 8474.5) ng/ml, p = 0.011]. Patients with active disease had higher levels [8552 (5463 12488)] than stable disease [5292.5 (3140.5-7310)], p = 0.002, and healthy controls [4896 (3194-8474.5)], p = 0.001. Changes in serial MRP8/14 level were associated with changes in disease activity, independent of steroid dose, p = 0.000. At R1, MRP 8/14 levels were lower than baseline in responders (n = 38) [9146.0 (6296.8-13693.8) vs 6501 (4314.8-8304.5), p = 0.004], but did not change in non-responders/relapsers (n = 14) [6693.5(4210.8-10516.3) vs 7755.0(5342 10741.0), p = 0.42]. Similar trend was observed at R2. MRP8/14 levels increased during follow-up in 66% and 26.3% of angiographic progressors and non progressors, respectively. MRP8/14 in TA may act as a novel biomarker with prognostic implications. PMID- 29196803 TI - Pulmonary function and high-resolution computed tomography examinations among offshore drill floor workers. AB - PURPOSE: The aim of this study was to assess short-term changes in pulmonary function in drill floor workers currently exposed to airborne contaminants generated as a result of drilling offshore. We also aimed to study the prevalence of pulmonary fibrosis using high-resolution computed tomography (HRCT) scans of another group of previously exposed drill floor workers. METHODS: Pulmonary function was measured before and after a 14-day work period in a follow-up study of 65 drill floor workers and 65 referents. Additionally, 57 other drill floor workers exposed to drilling fluids during the 1980s were examined with HRCT of the lungs in a cross-sectional study. RESULTS: The drill floor workers had a statistically significant decline in forced expiratory volume in 1 s (FEV1) across the 14-day work period after adjustment for diurnal variations in pulmonary function (mean 90 mL, range 30-140 mL), while the small decline among the referents (mean 20 mL, range - 30 to 70 mL) was not of statistical significance. Larger declines in FEV1 among drill workers were associated with the fewer number of days of active drilling. There were no signs of pulmonary fibrosis related to oil mist exposure among the other previously exposed drill floor workers. CONCLUSION: After 14 days offshore, a statistically significant decline in FEV1 was observed in the drill floor workers, which may not be related to oil mist exposure. No pulmonary fibrosis related to oil mist exposure was observed. PMID- 29196805 TI - Correction to: Abstracts : 29th European Congress of Pathology.

PMID- 29196804 TI - IgG4-related disease: with emphasis on the biopsy diagnosis of autoimmune pancreatitis and sclerosing cholangitis. AB - In 2011, chronic fibroinflammatory processes occurring simultaneously or metachronously in various organs and associated with elevated IgG4 serum levels and/or tissue infiltration with IgG4-positive plasma cells have been recognized as manifestations of a systemic disorder called IgG4-related disease (IgG4-RD). The histologic key findings are lymphoplasmacytic infiltration rich in IgG4 positive plasma cells combined with storiform fibrosis and obliterative phlebitis. Among the organs mainly affected by IgG4-RD are the pancreas and the extrahepatic bile ducts. The pancreatic and biliary alterations have been described under the terms autoimmune pancreatitis (AIP) and sclerosing cholangitis, respectively. These diseases are currently more precisely called IgG4-related pancreatitis (or type 1 AIP to distinguish it from type 2 AIP that is unrelated to IgG4-RD) and IgG4-related sclerosing cholangitis (IgG4-related SC). Clinically and grossly, both diseases commonly imitate pancreatic and biliary adenocarcinoma, tumors that are well known for their dismal prognosis. As IgG4-RD responds to steroid treatment, making a resection of a suspected tumor unnecessary, a biopsy is often required to establish the preoperative diagnosis. This review discusses the morphologic spectrum of IgG4-related pancreatitis and IgG4-related SC and focuses on the biopsy relevant histologic features for the diagnosis and differential diagnosis of these diseases. PMID- 29196806 TI - Sensitivity and requirement of improvements of four soybean crop simulation models for climate change studies in Southern Brazil. AB - Crop growth models have many uncertainties that affect the yield response to climate change. Based on that, the aim of this study was to evaluate the sensitivity of crop models to systematic changes in climate for simulating soybean attainable yield in Southern Brazil. Four crop models were used to simulate yields: AQUACROP, MONICA, DSSAT, and APSIM, as well as their ensemble. The simulations were performed considering changes of air temperature (0, + 1.5, + 3.0, + 4.5, and + 6.0 degrees C), [CO2] (380, 480, 580, 680, and 780 ppm), rainfall (- 30, - 15, 0, + 15, and + 30%), and solar radiation (- 15, 0, + 15), applied to daily values. The baseline climate was from 1961 to 2014, totalizing 53 crop seasons. The crop models simulated a reduction of attainable yield with temperature increase, reaching 2000 kg ha-1 for the ensemble at + 6 degrees C, mainly due to shorter crop cycle. For rainfall, the yield had a higher rate of reduction when it was diminished than when rainfall was increased. The crop models increased yield variability when solar radiation was changed from - 15 to + 15%, whereas [CO2] rise resulted in yield gains, following an asymptotic response, with a mean increase of 31% from 380 to 680 ppm. The models used require further attention to improvements in optimal and maximum cardinal temperature for development rate; runoff, water infiltration, deep drainage, and dynamic of root growth; photosynthesis parameters related to soil water availability; and energy balance of soil-plant system to define leaf temperature under elevated CO2. PMID- 29196807 TI - Recurrent parotid gland carcinoma: how effective is salvage surgery? AB - OBJECTIVE: Recurrent parotid gland carcinomas (PGCs) are poorly characterized and studies focusing on this topic are rare due to their low incidence. The goal of this study is to analyze the therapeutic strategies, prognostic factors, and oncological outcomes of a series of patients with recurrent PGCs. PATIENTS AND METHODS: Retrospective chart review (1997-2012) of patients with recurrent PGCs was initially treated with curative intent. RESULTS: We identified 20 patients with recurrent PGCs. Eleven patients presented isolated local, regional, or distant metastases, while the rest had recurrences in multiple sites. Recurrent tumors tended to present more advanced T-stage (p = 0.01) and overall stage (p < 0.001), but not N-stage (p = 0.74) when compared to the initial tumors. Half the patients (50%) had distant metastases at the moment of recurrence diagnosis, and another three developed them after attempted salvage surgery. Only 8/20 patients with isolated local or regional recurrences were surgically salvaged with extended revision parotidectomy and neck dissection, respectively. The remaining 12 patients were managed on palliative basis. Overall survival (31.70 months vs. 20.73 months) and progression-free survival (28.70 months vs. 13.61 months) were not significantly different in patients managed surgically vs. palliatively. CONCLUSION: Recurrent PGCs are aggressive neoplasms with a high rate of distant metastases. Surgical salvage can be considered in patients with limited local and/or regional recurrences. The alternative to surgical salvage is palliative management with different chemotherapeutic regimens. Survival does not differ between the two strategies in the present series. PMID- 29196808 TI - Propagation of alpha-synuclein pathology from the olfactory bulb: possible role in the pathogenesis of dementia with Lewy bodies. AB - Olfactory limbic structures, like the amygdala, the entorhinal, and the piriform cortices, are closely involved in cognitive processes. Thus, besides olfactory dysfunctions, it is conceivable that the compromise of these structures can lead to cognitive impairment. The olfactory bulb is affected by alpha-synuclein pathology in almost all cases of both Parkinson's disease and dementia with Lewy bodies. The clinical distinction between these disorders relies on the timing in the appearance of dementia in relationship to motor symptoms. Typically, it occurs late in the course of Parkinson's disease, and within the first year in dementia with Lewy bodies. The close anatomical proximity of the olfactory bulb with limbic regions, together with the early occurrence of cognitive impairment that is observed in dementia with Lewy bodies, raise the question whether the propagation of alpha-synuclein pathology in this condition might originate in the olfactory bulb, spreading from there to other limbic structures, and thereby reaching the associative neocortex. This review will describe the anatomical basis of the olfactory system and discuss the evidence of potential spreading pathways from the olfactory bulb that could support the presence of early dementia in the setting of Lewy body disorders. PMID- 29196809 TI - Melatonin affects membrane integrity, intracellular reactive oxygen species, caspase3 activity and AKT phosphorylation in frozen thawed human sperm. AB - Cryopreservation is known to induce oxidative stress in spermatozoa. Although melatonin has powerful antioxidant properties, little is known about its effects on human sperm quality during cryopreservation. The present study was undertaken to investigate the effects of melatonin treatment on human sperm parameters essential for fertilization. We first evaluated the effects of various concentrations of melatonin (0-15 mM) on human sperm parameters such as motility, viability and levels of intracellular reactive oxygen species during cryopreservation in order to identify an optimal dose with the greatest effects for further studies. Liquefied semen samples were then divided into three aliquots: cryopreserved without melatonin (control), cryopreserved with 3 mM melatonin and fresh groups. After being thawed, samples were evaluated for motility, viability, membrane integrity, intracellular reactive oxygen species levels, caspase-3 activity and AKT phosphorylation. Treatment of spermatozoa with the various concentrations of melatonin significantly increased their motility and viability and decreased their intracellular reactive oxygen species levels compared with the control group. The optimal melatonin concentration (3 mM) significantly decreased the intracellular reactive oxygen species levels, caspase 3 activity and the percentage of both dead and apoptotic-like sperm cells and increased the vitality, progressive motility and total motility and AKT phosphorylation compared with the control group. Thus, melatonin exerts protective effects against cryodamage during human spermatozoa cryopreservation and may exert its effects via the PI3K/AKT signaling pathway.

PMID- 29196811 TI - Cortical and subcortical connections of parietal and premotor nodes of the monkey hand mirror neuron network. AB - Mirror neurons (MNs) are a class of cells originally discovered in the monkey ventral premotor cortex (PMv) and inferior parietal lobule (IPL). They discharge during both action execution and action observation and appear to play a crucial role in understanding others' actions. It has been proposed that the mirror mechanism is based on a match between the visual description of actions, encoded in temporal cortical regions, and their motor representation, provided by PMv and IPL. However, neurons responding to action observation have been recently found in other cortical regions, suggesting that the mirror mechanism relies on a wider network. Here we provide the first description of this network by injecting neural tracers into physiologically identified IPL and PMv sectors containing hand MNs. Our results show that these sectors are reciprocally connected, in line with the current view, but IPL MN sectors showed virtually no direct connection with temporal visual areas. In addition, we found that PMv and IPL MN sectors share connections with several cortical regions, including the dorsal and mesial premotor cortex, the primary motor cortex, the secondary somatosensory cortex, the mid-dorsal insula and the ventrolateral prefrontal cortex, as well as subcortical structures, such as motor and polysensory thalamic nuclei and the mid dorsal claustrum. We propose that each of these regions constitutes a node of an "extended network", through which information relative to ongoing movements, social context, environmental contingencies, abstract rules, and internal states can influence MN activity and contribute to several socio-cognitive functions. PMID- 29196812 TI - Early elective delivery for fetal ventriculomegaly: are neurosurgical and medical complications mitigated by this practice? AB - PURPOSE: Antenatally diagnosed ventriculomegaly (VM) requires the balance of risks of neurological injury with premature delivery. The purpose of this study was to evaluate outcomes related to early elective delivery due to fetal VM at our institution. METHODS: We retrospectively assessed 120 babies (2008-2012) with antenatally diagnosed fetal VM. Inclusion criteria for ("early") cohort were (1) elective delivery occurred for expedited neurosurgical intervention between 32 and 36 weeks EGA and (2) fetal VM noted on official antenatal ultrasound. The comparative "near term" cohort differed only in that delivery occurred at 37+ weeks EGA. Statistical significance for comparative analyses set a priori at p < 0.05. RESULTS: Babies electively delivered early had a lower birthweight (p < 0.0001), greater ventricle width (p < 0.0001), and underwent initial CSF diversion sooner (p = 0.014). The early cohort (n = 22), compared to near term (n = 50), had a lower birthweight (p < 0.0001), greater ventricle width (p < 0.0001), and underwent initial CSF diversion sooner (p = 0.014). The early cohort required more repeat procedures: (45 vs. 22% p = 0.021), and VPS removals after VPS infections (41 vs. 12%, p = 0.010). Additionally, newborn respiratory failure (32 vs. 6%, p = 0.037) was more common. Finally, of four babies who died in the early cohort, 2/4 died for prematurity-associated pulmonary hypoplasia. CONCLUSIONS: While early elective delivery for fetal VM expedites intervention for rapidly expanding ventricles, few benefits were identified. Our study concluded those infants that were delivered earlier had increased VPS infections, repeat neurosurgical procedures, and medical co-morbidities. A multi institutional prospective observational study would be needed in order to confirm the clinical implications of such practice. PMID- 29196813 TI - Sense-encoded poly-GR dipeptide repeat proteins correlate to neurodegeneration and uniquely co-localize with TDP-43 in dendrites of repeat-expanded C9orf72 amyotrophic lateral sclerosis. AB - Hexanucleotide repeat expansions in C9orf72 are the most common genetic cause of amyotrophic lateral sclerosis (C9 ALS). The main hypothesized pathogenic mechanisms are C9orf72 haploinsufficiency and/or toxicity from one or more of bi directionally transcribed repeat RNAs and their dipeptide repeat proteins (DPRs) poly-GP, poly-GA, poly-GR, poly-PR and poly-PA. Recently, nuclear import and/or export defects especially caused by arginine-containing poly-GR or poly-PR have been proposed as significant contributors to pathogenesis based on disease models. We quantitatively studied and compared DPRs, nuclear pore proteins and C9orf72 protein in clinically related and clinically unrelated regions of the central nervous system, and compared them to phosphorylated TDP-43 (pTDP-43), the hallmark protein of ALS. Of the five DPRs, only poly-GR was significantly abundant in clinically related areas compared to unrelated areas (p < 0.001), and formed dendritic-like aggregates in the motor cortex that co-localized with pTDP 43 (p < 0.0001). While most poly-GR dendritic inclusions were pTDP-43 positive, only 4% of pTDP-43 dendritic inclusions were poly-GR positive. Staining for arginine-containing poly-GR and poly-PR in nuclei of neurons produced signals that were not specific to C9 ALS. We could not detect significant differences of nuclear markers RanGap, Lamin B1, and Importin beta1 in C9 ALS, although we observed subtle nuclear changes in ALS, both C9 and non-C9, compared to control. The C9orf72 protein itself was diffusely expressed in cytoplasm of large neurons and glia, and nearly 50% reduced, in both clinically related frontal cortex and unrelated occipital cortex, but not in cerebellum. In summary, sense-encoded poly GR DPR was unique, and localized to dendrites and pTDP43 in motor regions of C9 ALS CNS. This is consistent with new emerging ideas about TDP-43 functions in dendrites. PMID- 29196814 TI - Identification of candidate pathogenicity determinants of Rhizoctonia solani AG1 IA, which causes sheath blight disease in rice. AB - Sheath blight disease is one of the predominant diseases of rice and it is caused by the necrotrophic fungal pathogen Rhizoctonia solani. The mechanistic insight about its widespread success as a broad host range pathogen is limited. In this study, we endeavor to identify pathogenicity determinants of R. solani during infection process in rice. Through RNAseq analysis, we identified a total of 65 and 232 R. solani (strain BRS1) genes to be commonly upregulated in three different rice genotypes (PB1, Tetep, and TP309) at establishment and necrotrophic phase, respectively. The induction of genes encoding extracellular protease, ABC transporter, and transcription factors were notable during establishment phase. While during necrotrophic phase, several CAZymes, sugar transporters, cellular metabolism, and protein degradation-related genes were prominently induced. We have also identified few putative secreted effector encoding genes that were upregulated during pathogenesis. The qPCR analysis further validated the phase-specific expression dynamics of some selected putative effectors and pathogenicity-associated genes. Overall, the present study reports identification of key genes and processes that might be crucial for R. solani pathogenesis. The ability to effectively damage host cell wall and survive in hostile plant environment by managing oxidative stress, cytotoxic compounds, etc. is being proposed to be important for pathogenesis of R. solani in rice. The functional characterization of these genes would provide key insights about this important pathosystem and facilitate development of strategies to control this devastating disease. PMID- 29196816 TI - Extended nursing for the recovery of urinary functions and quality of life after robot-assisted laparoscopic radical prostatectomy: a randomized controlled trial. AB - PURPOSE: The purpose of this work is to explore the effects of continuing nursing care intervention on postoperative urinary control and quality of life among patients with prostate cancer. METHODS: This was a single-center, parallel, and randomized controlled trial that was carried out at the Department of Urology, the First Affiliated Hospital of Anhui Medical University, China. The participants underwent robot-assisted laparoscopic radical prostatectomy (RARP) between October 2014 and April 2016. The patients were randomized to the experimental and control groups (n=37/group). Patients in the control group received routine nursing care, while patients in the experimental group received continuing nursing care. During the 6-month follow-up, each patient was invited at the hospital discharge and at 1, 3, and 6 months to fill the ICI-Q-SF and SF 36 questionnaires. RESULTS: The scores of urinary incontinence were improved in the intervention group compared with controls at 3 and 6 months after discharge (both P < 0.01). The scores of quality of life in the experimental group were significantly higher than control group at 1, 3, and 6 months (all P < 0.01). Adverse events were mild or moderate in intensity and were resolved in all patients. All adverse events were related to RARP. CONCLUSIONS: Continuing nursing care intervention had significant beneficial effects on urinary functions and quality of life in patients with prostate cancer after RARP. This approach warrants to be promoted in the clinical setting. PMID- 29196817 TI - Identification and characterization of a new potyvirus infecting cucurbits. AB - A new potyvirus, tentatively named cucurbit vein banding virus (CVBV), was identified in crops of cucurbits in San Pedro (Buenos Aires, Argentina). The complete genome sequences of two isolates of CVBV were obtained by next generation sequencing (Illumina). The genomic RNA consisted of 9968 and 9813 nucleotides, respectively, and displayed typical potyvirus organization. The percentage identity for these two genome sequences, using BLASTn, was 77% to sweet potato virus c and 73% to tomato necrotic stunt virus. BLASTx analysis of the complete polyprotein showed that the most closely related virus is plum pox virus, with 48% amino acid sequence identity for both isolates. Sequence comparisons and phylogenetic analyses indicate that CVBV belongs to a previously undescribed species in genus Potyvirus. PMID- 29196818 TI - Detection in Japan of an equine-like G3P[8] reassortant rotavirus A strain that is highly homologous to European strains across all genome segments. AB - Equine-like G3P[8] rotavirus A strains with DS-1-like backbone genes have emerged since 2013. An equine-like RVA/Human-wt/JPN/15R429/2015/G3P[8] strain possessing I2-R2-C2-M2-A2-N2-T2-E2-H2 was detected in Japan in 2015. Its VP7 gene was >= 99.3% identical to those of equine-like G3P[4] strains detected in Japan, and the remaining 10 genes were 98.6-99.8% identical to G1P[8] double-gene reassortants detected in Japan, Thailand and the Philippines. Thus, 15R429 was likely generated through reassortment between the equine-like G3P[4] and G1P[8] reassortant strains. Notably, 15R429 was 98.5-99.8% identical across all 11 genes of the equine-like G3P[8] strains detected in Spain and Hungary in 2015. PMID- 29196815 TI - Amyloid beta oligomers (AbetaOs) in Alzheimer's disease. AB - The causative role of amyloid beta 1-42 (Abeta42) aggregation in the pathogenesis of Alzheimer's disease (AD) has been under debate for over 25 years. Primarily, scientific efforts have focused on the dyshomeostasis between production and clearance of Abeta42. This imbalance may result from mutations either in genes for the substrate, i.e., amyloid precursor protein or in genes encoding presenilin, the enzyme of the reaction that generates Abeta42. Currently, it is supposed that soluble oligomers of amyloid beta (AbetaOs) and not fibrillar Abeta42 within neuritic plaques may be the toxic factors acting on a very early stage of AD, perhaps even initiating pathological cascade. For example, soluble AbetaOs isolated from AD patients' brains reduced number of synapses, inhibited long-term potentiation, and enhanced long-term synaptic depression in brain regions responsible for memory in animal models of AD. Concentrations of AbetaOs in the cerebrospinal fluid (CSF) of AD patients are often reported higher than in non-demented controls, and show a negative correlation with mini-mental state examination scores. Furthermore, increased Abeta42/oligomer ratio in the CSF of AD/MCI patients indicated that the presence of soluble AbetaOs in CSF may be linked to lowering of natively measured monomeric Abeta42 by epitopes masking, and hence, concentrations of AbetaOs in the CSF are postulated to as useful AD biomarkers. PMID- 29196819 TI - An effective delivery vehicle of demineralized bone matrix incorporated with engineered collagen-binding human bone morphogenetic protein-2 to accelerate spinal fusion at low dose. AB - The aim of this study was to investigate the feasibility and efficacy of a new delivery matrix using demineralized bone matrix (DBM) incorporated with collagen binding bone morphogenetic protein-2 (CBD-BMP-2) in the rat inter-transverse spinal fusion model. Sixty rats undergoing posterolateral (inter-transverse) spinal fusion were divided into 3 groups according to the fusion materials containing different components (n = 20 per group). Group A were implanted with DBM, Group B with combination of DBM and BMP-2 and Group C with combination of DBM and CBD-BMP-2. After surgery, the spinal fusion of all the rats was assessed by plain radiography, CT + 3D reconstruction, manual palpation and histological evaluation. Significant difference was found in terms of solid fusion rate among the three groups, with 95% in Group C, 65% in Group B and 0% in Group A (P < 0.001). Compared with Groups B and A, new bone formation was observed earlier and was obvious larger, trabecular bone microarchitecture assessment was better and bone mineral density was statistically larger in Group C. In addition, more newly woven bone and osteocytes were shown by histological evaluation in Group C at 4 weeks post-operation. The present study showed CBD domain could help BMP-2 to improve the efficiency of posterolateral spinal fusion. DBM scaffold activated by collagen-binding BMP-2 was a feasible and promising bone repair vehicle. The present study showed better results in terms of plain radiography, CT + 3D reconstruction, manual palpation and histological evaluation in the rat inter transverse spinal fusion model using DBM+CBD-BMP-2, compared with DBM+BMP-2 and DBM alone, indicating DBM scaffold activated by collagen-binding BMP-2 was a feasible and promising bone repair vehicle. PMID- 29196820 TI - Functional roles of agmatinase during the peri-implantation period of pregnancy in sheep. AB - This study investigated the effect of agmatine (Agm) in proliferation of ovine trophecdoderm cells (oTr1) as well as the importance of the arginine decarboxylase (ADC) and agmatinase (AGMAT) alternative pathway for synthesis of polyamines in ovine conceptuses during the peri-implantation period of pregnancy. Morpholino antisense oligonucleotides (MAOs) were used to inhibit translation of mRNAs for ODC1 alone, AGMAT alone, and their combination. Rambouillet ewes (N = 50) were assigned randomly to the following treatments on Day 8 of pregnancy: MAO control (n = 10); MAO-ODC1 (n = 8); MAO-ADC (n = 6); MAO-ODC1:MAO-ADC (n = 9); or MAO-ODC1:MAO-AGMAT (n = 9). Ewes were ovario-hysterectomized on Day 16 of pregnancy to obtain uterine flushings, uterine endometrium, and conceptus tissues. Inhibition of translation of both ODC1 and AGMAT resulted in 22% of ewes having morphologically and functionally normal (elongated and healthy) conceptuses designated MAO-ODC1:MAO-AGMAT (A). But, 78% of the MAO-ODC1:MAO-AGMAT ewes had morphologically and functionally abnormal (not elongated and fragmented) conceptuses designated MAO-ODC1:MAO-AGMAT (B). The pregnancy rate was less (22%; P < 0.05) for MAO-ODC1:MAO-AGMAT ewes than for MAO-control (80%), MAO-ODC1 (75%), MAO-ADC (84%), and MAO-ODC1:MAO-ADC (44%) ewes. Moreover, inhibition of translational of both ODC1 and AGMAT mRNAs increased expression of ADC, SLC22A1, SLC22A2, and SLC22A3 mRNAs, as well as abundances of agmatine, putrescine, spermindine, and spermine in conceptus tissue. However, MAO-ODC1:AGMAT(B) ewes had greater abundances of agmatine, putrescine, and spermidine and reduced amounts of spermine in uterine flushes. Thus, in vivo knockdown of translation of ODC1 and AGMAT mRNAs increased expression of genes for the synthesis and transport of polyamines in ovine conceptuses during the peri-implantation period of pregnancy. PMID- 29196821 TI - The predictive value of MRI in the syndesmotic instability of ankle fracture. AB - OBJECTIVE: Although many types of ankle fracture can be combined with syndesmosis injury, preoperative imaging studies rarely reveal instability of the syndesmosis. This study assessed the use of magnetic resonance imaging (MRI) for syndesmotic instability in patients with unstable ankle fracture. METHODS: A total of 74 patients who were treated for Lauge-Hansen supination external rotation/Weber B type fracture or pronation external rotation/Weber C type fracture and who underwent MRI for preoperative assessment were enrolled. The MRI findings of the syndesmotic ligament and the results of an intraoperative stress test were evaluated. RESULTS: Twenty-six patients had a positive result on the intraoperative stress test for syndesmotic instability. The MRI findings of the syndesmotic ligaments revealed that complete tear of the posterior inferior tibiofibular ligament (PITFL) was the most reliable predictor of syndesmotic instability (sensitivity, 74%; specificity, 78%; positive predictive value, 54%). Interobserver agreement for the intraoperative stress test and MRI assessment was excellent, except for the MRI findings of the interosseous ligament (62% agreement; kappa, 0.3). CONCLUSIONS: Complete tear of the PITFL on MRI has additional diagnostic value for syndesmotic instability in ankle fracture. However, because the sensitivity might not be sufficient to justify the costs associated with MRI, cost-effectiveness should be considered. PMID- 29196822 TI - Osteogenic melanoma: report of a case mimicking osteosarcoma and review of the literature. AB - A 32-year-old male presented with a right thumb lesion of 11-month duration. A clinical diagnosis of pyogenic granuloma was entertained but the lesion failed to respond to conservative therapy and eventually necessitated amputation of his thumb. MRI of the right thumb showed an ill-defined, heterogeneously enhancing, infiltrating mass within the dorsal soft tissues abutting the distal phalanx and measuring 4.2 * 2.4 * 0.7 cm. Histologically, the tumor was composed of a high grade osteosarcoma with a chondrosarcomatous component localized within the underlying bone and a more superficial spindle cell component in the overlying soft tissue. The epidermis was focally ulcerated overlying the lesion. The key to the diagnosis was provided by intense staining of the spindle cell component for S100 protein indicative of a spindle cell melanoma. The presence of an associated osteogenic sarcomatous component established a final diagnosis of osteogenic melanoma. The localization of this element to phalangeal bone is distinctly unusual and resulted in the close resemblance to a primary osteogenic sarcoma. PMID- 29196824 TI - Spirochetal Lipoproteins in Pathogenesis and Immunity. AB - Lipoproteins are lipid-modified proteins that dominate the spirochetal proteome. While found in all bacteria, spirochetal lipoproteins have unique features and play critical roles in spirochete biology. For this reason, considerable effort has been devoted to determining how the lipoproteome is generated. Essential features of the structural elements of lipoproteins are now understood with greater clarity, enabling greater confidence in identification of lipoproteins from genomic sequences. The journey from the ribosome to the outer membrane, and in some cases, to the cellular surface has been defined, including secretion, lipidation, sorting, and export across the outer membrane. Given their abundance and importance, it is not surprising that spirochetes have developed a number of strategies for regulating the spatiotemporal expression of lipoproteins. In some cases, lipoprotein expression is tied to various environmental cues, while in other cases, it is linked to growth rate. This regulation enables spirochetes to express certain lipoproteins at high levels in one phase of the spirochete lifecycle, while dramatically downregulating the same lipoproteins in other phases. The mammalian host has developed specialized mechanisms for recognizing lipoproteins and triggering an immune response. Evasion of that immune response is essential for spirochete persistence. For this reason, spirochetes have developed mechanisms for altering lipoproteins. Lipoproteins recognized by antibodies formed during infection are key serodiagnostic antigens. In addition, lipoprotein vaccines have been developed for generating an immune response to control or prevent a spirochete infection. This chapter summarizes our current understanding of lipoproteins in interactions of spirochetes with their hosts. PMID- 29196823 TI - Quantitative mapping of glenohumeral cartilage in asymptomatic subjects using 3 T magnetic resonance imaging. AB - OBJECTIVE: The purpose of this study was to develop quantitative T2 mapping methodology in asymptomatic shoulders for the entire mappable region of the glenohumeral cartilage in the coronal and sagittal planes, to assess the feasibility and limitations of the development of a diagnostic tool for future application in symptomatic patients. MATERIALS AND METHODS: Twenty-one asymptomatic volunteers underwent sagittal and coronal glenohumeral T2 mapping, as the spherical geometry of the humeral head obviates the need to evaluate the entire glenohumeral cartilage in a single plane. The humeral head cartilage orthogonal to the mapping plane was manually segmented in the sagittal and coronal planes, whereas the glenoid cartilage was segmented in the coronal plane. Cartilage T2 summary statistics were calculated and coverage in each mapping plane was qualitatively assessed. RESULTS: The mean +/- standard deviation of the glenoid cartilage T2 was 38 +/- 2 ms. The coronal and sagittal mapping planes captured different regions of the humeral head with some overlap: inferior-medial to superior-lateral versus superior/superior-lateral to anterior-lateral and posterior-lateral respectively. The mean humeral head cartilage T2 in the coronal plane was 41 +/- 3 ms, which was significantly different (p < 0.05) from the sagittal plane mean of 34 +/- 2 ms. CONCLUSION: This study measured characteristic glenoid and humeral head cartilage T2 values over the area mappable with two planes. Importantly, this study demonstrated that two dimensional mapping in a single plane or two combined planes cannot capture the entirety of the semi-spherical humeral head cartilage. This highlights the need for three-dimensional T2 mapping techniques in the shoulder. PMID- 29196826 TI - Botulinum toxin: a novel therapy for clozapine-induced sialorrhoea. PMID- 29196825 TI - Changes in prescription patterns in older hospitalized patients: the impact of FORTA on disease-related over- and under-treatments. AB - PURPOSE: Physicians often face difficulties in choosing appropriate medications for multimorbid older people. The FORTA (Fit for the Aged) classification (A: absolutely, B: beneficial, C: careful, D: don't) was proposed as a clinical tool for improving the quality of drug treatment in the aged. As an implicit tool, FORTA has been shown to aid medication optimization and improve clinical end points in the VALFORTA trial. In this prospective randomized controlled study, 207 older hospitalized patients received standard geriatric treatment and 202 patients received FORTA-guided treatment. METHODS: Here, changes of drug prescriptions at the anatomical-therapeutic-chemical system (ATC) level were evaluated separately for important diagnoses in descriptive analyses; over- and under-treatment rates were compared between groups. RESULTS: At the individual drug/drug class level related to all important diagnoses, the application of FORTA significantly improved under-treatments for 12 drugs/drug classes (e.g., ACE inhibitors to treat arterial hypertension) and over-treatments for 7 drugs/drug classes (e.g., proton pump inhibitors to treat gastroesophageal reflux disease). CONCLUSIONS: FORTA representing the first combined positive/negative labeling approach at the individual drug level aids the optimization of drug treatment in older people as detected for drugs/drug classes at the ATC level in important indications. FORTA is effective in addressing over- and under treatments even if analyzed for smaller subgroups of VALFORTA. PMID- 29196827 TI - Bone marrow aspirations in oncological patients: experience from an in-house standard in paediatrics. AB - BACKGROUND: Nearly all paediatric patients require deep sedation when undergoing bone marrow aspiration (BMA). We analyzed the data from our protocols documented in a standardised procedure for bone marrow puncture over a period of 2 years. METHODS: Our standard included the documentation of personal data as well as vital parameters. In addition, we documented all medications administered, potential complications and required intervention measures, as necessary. RESULTS: A total of 107 protocols were available for the evaluation. Our standard covered the usage of midazolam and S-ketamine and resulted in complications in just 9 patients, which could be remedied using simple measures. For both active substances, the dosage necessary to reach sufficient deep analgosedation was significantly higher for patients under 24 months of age. CONCLUSIONS: Our standard for BMA provides a practical and feasible procedure. In addition to good examination conditions, our standard also helps ensure the safety of our patients. PMID- 29196828 TI - Space Use and Social Mating System of the Hantavirus Host, Oligoryzomys longicaudatus. AB - The long-tailed mouse, Oligoryzomys longicaudatus (Cricetidae: Sigmodontinae), is the major host of Andes hantavirus, the etiological agent of hantavirus pulmonary syndrome in the south of Argentina and Chile. Studying the ecology of this species is necessary to understand how Andes hantavirus is maintained in nature. In this study, we examine the home range size and intra- and intersexual overlap degree of male and female O. longicaudatus in order to elucidate the mating system of this species. To our knowledge, this research provides the first documentation, obtained from a specific design, of spacing and mating systems in this species in Argentina. The study was conducted seasonally from April (autumn) 2012 to October (spring) 2013 in a shrubland habitat of Cholila, Andean region, Argentina. We studied spacing patterns using 59 and 51 home ranges established by adult males and females, respectively, in two 3.24 ha capture-marked and recapture grids. Significant differences between sexes in home range size and overlap degree were found. Male home ranges were always larger than those of females. We observed exclusive space use both among males and females (13.15 +/- 18.67, and 3.60 +/- 3.43%, respectively). Considering only those males that get access to receptive females (40%), average intersexual overlap value was about 30.82 +/- 19.73%. Sexual differences in home range sizes and the spatial avoidance between breeding males, that would reflect intrasexual competition for receptive females, allows us to propose a polygynous mating system for O. longicaudatus. PMID- 29196829 TI - Investigation of fullerenol-induced changes in poroelasticity of human hepatocellular carcinoma by AFM-based creep tests. AB - In this study, atomic force microscopy (AFM) is used to investigate the alterations of the poroelastic properties of hepatocellular carcinoma (SMMC-7721) cells treated with fullerenol. The SMMC-7721 cells were subject to AFM-based creep tests, and a corresponding poroelastic indentation model was used to determine the poroelastic parameters by curve fitting. Comparative analyses indicated that the both permeability and diffusion of fullerenol-treated cells increased significantly while their elastic modulus decreased by a small amount. From the change in the trend of the determined parameter, we verified the corresponding alternations of cytoskeleton (mainly filaments actin), which was reported by the previous study using confocal imaging method. Our investigation on SMMC-7721 cell reveals that the poroelastic properties could provide a better understanding how the cancer cells are affected by fullerenol or potentially other drugs which could find possible applications in drug efficacy test, cancer diagnosis and secure therapies. PMID- 29196830 TI - A Multi-site In-depth Evaluation of the Quanterix Simoa from a User's Perspective. AB - An in-depth evaluation of the Quanterix(c) SimoaTM platform was undertaken by scientists from the AAPS Emerging Technologies Focus Group to determine the overall performance of the technology as well as provide guidance to future users. In order to test the platform in a non-GLP bioanalytical setting, a cross site evaluation of the Quanterix IL-6 biomarker kit was performed. Parameters tested during this evaluation included sensitivity, accuracy and precision, and parallelism in human serum from normal individuals. The results demonstrated improved sensitivity compared to the claimed sensitivity of other commercially available IL-6 kits and showed excellent site-to-site reproducibility. Observed issues included difficulties with system reliability and a lack of parallelism and specificity in a subset of samples. Overall, these results demonstrate that while there are challenges to the Simoa platform this technology offers automation capabilities and excellent sensitivity that enhance bioanalysis especially of low-abundance analytes.

Search strategy was developed based on the PICO Question "Does the use of lasers after oral surgery improve bone healing?". Eligibility criteria were: being on laser; evaluate bone healing; involve oral surgery; do not be about implant, periodontics, orthodontics, osteonecrosis or radiotherapy, nor revisions, clinical cases, etc. Data were collected from each article in a structured spreadsheet and a descriptive analysis was performed. Risk assessment of bias of the articles was carried out through the tool elaborated by the Cochrane collaboration. A total of 827 potentially relevant references were identified. No articles were found in OpenGray. Eleven articles met the eligibility criteria and were included in the systematic review. Most of studies were in vivo and in jaw, being conducted with low-power lasers which were applied immediately after the surgical procedure of extraction. Neoformation and bone density were the outcomes of choice and there was a tendency of increase in bone density, neoformation, regeneration, mineralization, or bone condensation when laser was applied. Regarding the bias risk assessment, studies were not clear in reporting most of the parameters. Low-power laser therapy seems to reduce time of bone healing in oral surgery, although there are no defined protocols and the level of evidence is still considered weak. PMID- 29196833 TI - Chondroitin sulfate and glucosamine sulfate associated to photobiomodulation prevents degenerative morphological changes in an experimental model of osteoarthritis in rats. AB - The aim of this study was to compare the effects of combined treatment with chondroitin sulfate and glucosamine sulfate (CS/Gl) and photobiomodulation (PBM) on the degenerative process related to osteoarthritis (OA) in the articular cartilage in rats. Forty male Wistar rats were randomly divided into four groups: OA control group (CG); OA animals submitted to PBM treatment (PBM); OA animals submitted to CS/Gl treatment (CS/Gl); OA submitted to CS/GS associated with PBM treatments (GS/Gl + PBM). The CS/Gl started 48 h after the surgery, and they were performed for 29 consecutive days. Moreover, PBM was performed after the CS/Gl administration on the left joint. Morphological characteristics and immunoexpression of interleukin 10 (IL-10) and 1 beta (IL-1beta) and collagen type II (Col II) of the articular cartilage were evaluated. The results showed that all treated groups (CS/Gl and PBM) presented attenuation signs of degenerative process (measured by histopathological analysis) and lower density chondrocytes [PBM (p = 0.0017); CS/Gl (p = 0.0153) and CS/Gl + PBM (p = 0.002)]. Additionally, CS/Gl [associated (p = 0.0089) or not with PBM (p = 0.0059)] showed significative lower values for OARSI grade evaluation. Furthermore, CS/GS + PBM decreased IL-1beta protein expression (p = 0.0359) and increased IL-10 (p = 0.028) and Col II imunoexpression (p = 0.0204) compared to CG. This study showed that CS/Gl associated with PBM was effective in modulating inflammatory process and preventing the articular tissue degradation in the knees OA rats.

AB - Perceiving a direct gaze (i.e. another individual's gaze directed to the observer leading to eye contact) influences positively a wide range of cognitive processes. In particular, direct gaze perception is known to stimulate memory for other's faces and to increase their likeability. Alzheimer's disease (AD) results in social withdrawal and cognitive decline. However, patients show preserved eye contact behaviours until the middle stage of the disease. The eye contact effects could be preserved in AD and be used to compensate for cognitive and social deficits. Yet, it is unknown whether these effects are preserved in normal ageing. The aim of this study was to address whether the positive effects of eye contact on memory for faces and likeability of others are preserved in healthy older adults and in patients with early to mild AD. Nineteen AD patients, 20 older adults and 20 young adults participated in our study. Participants were first presented with faces displaying either direct or averted gaze and rated each face's degree of likeability. They were then asked to identify the faces they had previously seen during a surprise recognition test. Results showed that the effect of eye contact on other's likeability was preserved in normal ageing and in AD. By contrast, an effect of eye contact on memory for faces seems to emerge only in young participants, suggesting that this effect declines with ageing. Interestingly, however, AD patients show a positive correlation between ratings of likeability and recognition scores, suggesting that they implicitly allocated their encoding resources to most likeable faces. These results open a new way for a "compensating" therapy in AD.

AB - Dual tasking, or the simultaneous execution of two continuous tasks, is frequently associated with a performance decline that can be explained within a capacity sharing framework. In this study, we assessed the effects of a concurrent motor task on the efficiency of visual information uptake based on the 'theory of visual attention' (TVA). TVA provides parameter estimates reflecting distinct components of visual processing capacity: perceptual threshold, visual processing speed, and visual short-term memory (VSTM) storage capacity. Moreover, goodness-of-fit values and bootstrapping estimates were derived to test whether the TVA-model is validly applicable also under dual task conditions, and whether the robustness of parameter estimates is comparable in single- and dual-task conditions. 24 subjects of middle to higher age performed a continuous tapping task, and a visual processing task (whole report of briefly presented letter arrays) under both single- and dual-task conditions. Results suggest a decline of both visual processing capacity and VSTM storage capacity under dual-task conditions, while the perceptual threshold remained unaffected by a concurrent motor task. In addition, goodness-of-fit values and bootstrapping estimates support the notion that participants processed the visual task in a qualitatively comparable, although quantitatively less efficient way under dual-task conditions. The results support a capacity sharing account of motor-cognitive dual tasking and suggest that even performing a relatively simple motor task relies on central attentional capacity that is necessary for efficient visual information uptake. PMID- 29196836 TI - Modifiable and non-modifiable risk factors for preterm delivery among adolescent and young adult cancer survivors. AB - PURPOSE: A cancer diagnosis in adolescence and young adulthood (AYA, ages 15-39) may affect future pregnancy outcomes. Previous studies have reported an increased risk of preterm delivery (< 37 weeks of gestation) after maternal cancer treatment. In this analysis, we evaluated whether non-cancer characteristics modify the association between an AYA cancer history and preterm birth. METHODS: North Carolina Central Cancer Registry records (2000-2013) were linked to state birth certificate files (2000-2014) to identify births to AYA cancer survivors (n = 1,980). A comparison cohort of births to women without a cancer diagnosis was selected from birth certificate files (n = 11,860). Log-binomial regression was used to estimate risk ratios (RR) and 95% confidence intervals (CI) for preterm delivery. Effect modification by early prenatal care (1st trimester; yes/no), race/ethnicity (white/black/other), previous live births (0/1+), maternal age (< 25/25-29/30-34/35+), smoking during pregnancy (any/none), and education (high school or less/some college/Bachelor's degree or higher) was evaluated using likelihood ratio tests (LRT). RESULTS: Overall, preterm births were more common among AYA survivors than the comparison group (RR = 1.24, CI 1.07-1.43). The association was stronger among those who did not receive early prenatal care (RR = 1.73, CI 1.26-2.37) than among those who did (RR = 1.15, CI 0.98-1.35; LRT p = 0.03). Maternal age < 25 was also associated with a greater increase in preterm birth (< 25: RR = 1.80, CI 1.27-2.54; LRT p = 0.07). Associations did not vary strongly by other factors evaluated. CONCLUSIONS: An AYA cancer diagnosis may be associated with an increased risk of preterm birth, particularly among women who are younger and receive late or no prenatal care. PMID- 29196837 TI - Protective effect of aspirin treatment on mouse behavior in the acute phase of experimental infection with Trypanosoma cruzi. AB - Chagas disease is a potentially fatal disease caused by the parasite Trypanosoma cruzi, which can in some cases affect the central nervous system. The objective was to evaluate the effect of aspirin (ASA) in the behavior of mice infected with T. cruzi during the acute phase. This was an experimental study with random assignation. Twenty four BALB/c mice were divided into four groups of six animals each as follows: only ASA (OA), ASA before infection (BI), ASA after infection (AI) and only infection (OI). The strain used for infection was M/HOM/Bra/53/Y. An ASA dose of 100 mg/kg per day was administered 72 h before infection to BI group and the same dose 48 h after infection to AI group. Mice behavior in the open field test, mortality, and brain histopathology was evaluated. Data were analyzed using ANOVA, chi square test, and Kaplan-Meier with long-rank for survival analysis. In the open field test, the OA group has similar results with the BI group, in the variables of immobility and escape. Also, the OA group displayed significantly higher rates of micturition (p < 0.001) and defecation (p < 0.001) compared to infected groups. Mortality was higher in BI group (p = 0.02). The presence of T. cruzi amastigotes were higher in brain tissues of the AI and OI groups (p = 0.008). In conclusion, the administration of ASA before infection seemed to prevent behavioral changes induced by the acute infection, but it led to accelerated mortality. The study highlighted the potential importance of the pathways inhibited by ASA in the early hours of acute infection with T. cruzi. PMID- 29196838 TI - Inverse correlation between left ventricular end-diastolic pressure and contrast induced nephropathy in patients undergoing percutaneous coronary intervention. AB - BACKGROUND: There is a rising incidence of contrast-induced nephropathy (CIN), which is defined as either a 25% relative increase or an absolute increase of 0.5 mg/dL (44.2 umol/L) in the serum creatinine (Scr) level at 48-72 h after administration of iodinated contrast media (CM). We investigated the relationship between left ventricular end-diastolic pressure (LVEDP) and CIN in patients undergoing percutaneous coronary intervention (PCI). METHODS: A total of 431 consecutive patients with coronary artery disease undergoing PCI were divided into four groups based on LVEDP quartile cut-off points. Enrolled patients were given continuous intravenous infusion of normal saline starting 4 h before PCI and lasting 24 h. At the end of hydration administration, 20 mg furosemide was slowly injected intravenously. Serum creatinine (Scr), creatinine clearance rate (Ccr), and glomerular filtration rate (GFR) were detected before and after PCI. RESULTS: There were significant differences in the incidences of CIN in the four groups: 10.25% in the Q1 group, 5.55% in the Q2 group, 5.31% in the Q3 group, and 1.06% in the Q4 group (P < 0.05). With increasing LVEDP, the incidence of CIN decreased significantly (OR 0.581, 95% CI 0.367-0.920). Received operating characteristic curve analysis of the predictive value of LVEDP for CIN produced area under the curve values was 0.641, with a sensitivity of 74.1% and specificity of 48%. The optimal LVEDP cut-off for the occurrence of CIN was 14.5 mmHg. CONCLUSIONS: LVEDP correlated inversely with CIN in patients undergoing PCI. PMID- 29196839 TI - Purification and activity characterization of polysaccharides in the medicinal lichen Umbilicaria tornata from Taibai Mountain, China. AB - Water-soluble polysaccharides from Umbilicaria tornata (UTP) were purified and preliminarily characterized. The antioxidant and antitumor activities of crude UTP and two purified fractions (UTP-1 and UTP-2) were evaluated using in vitro experiments. The results showed that the molecular weights of UTP-1 and UTP-2 were 84.86 and 28.66 kDa, respectively. Both UTP-1 and UTP-2 were composed of glucose and xylose, with their molar ratios being 1.3:0.9 and 0.9:4.6, respectively. In addition, crude UTP, UTP-1 and UTP-2 showed dose-dependent DPPH and hydroxyl radical scavenging and reducing activities. However, crude UTP exhibited stronger antioxidant activity than UTP-1 and UTP-2, particularly in terms of DPPH radicals. Crude UTP and the two purified fractions inhibited the growth of HeLa, HepG2, A375, MCF-7, SGC7901 and Caco2 cancer cells in vitro. Compared with UTP-1 and UTP-2, crude UTP presented significantly higher antitumor activity in vitro against HeLa and HepG2 cells (p < 0.05). These findings provide a scientific basis for the deeper exploration and resource development of U. tornata. PMID- 29196840 TI - Conception of the Lubeck Toolbox curriculum for basic minimally invasive surgery skills. AB - PURPOSE: Difficulties at the beginning of the learning curve in minimally invasive surgery (MIS) can well be overcome by simulation outside the operating room. Despite a great number of available devices, standardized, structured, and validated training curricula for video simulators are scarce. METHODS: The Lubeck Toolbox (LTB) video trainer provides six training modules and online video tutorials. Proficiency levels for the tasks were defined by performance analysis of MIS experts (n = 15). Mean values of the best performed repetitions were set as benchmarks for a validation study with n = 30 MIS novices and the learning curves calculated. The novices performed a cholecystectomy on a pig organ model before and after the curriculum which were analyzed using the GOALS score. RESULTS: Benchmarks defined by expert performance for the task Nos. 1 to 6 were 72 s (+/- 8) (Pack Your Luggage), 49 s (+/- 9) (Weaving), 66 s (+/- 10) (Chinese Jump Rope), 89 s (+/- 28) (Triangle Cut), 138 s (+/- 44) (Hammer Cut), and 98 (+/ 22) (Suturing). The median numbers of required repetitions by the novices to reach the proficiency level were n = 42 (7-80), n = 26 (9-55), n = 32 (14-77), n = 44 (15-59), n = 19 (6-68), and n = 26 (15-60). These values were all located at the beginning of the plateau phase of the learning curves. GOALS score improved significantly after completion of the curriculum (18.0 (+/- 2.6) vs. 10.9 (+/- 1.6), p < 0.0001). CONCLUSION: The LTB curriculum constitutes a new highly standardized and proficiency level-based training program for basic skills in MIS. Transferability of the task content to a (sub)-realistic environment could be demonstrated. Still, future trials will have to further validate the effectiveness of the LTB curriculum. PMID- 29196841 TI - Implication of visceral obesity in patients with esophageal squamous cell carcinoma. AB - PURPOSE: Visceral obesity is considered to be associated not only with chronic systemic inflammation but also with aggressive cancer behavior. However, the implication of visceral obesity in patients with esophageal squamous cell carcinoma (ESCC) is unclear. METHODS: Computed tomography volumetry was performed in 364 patients who underwent esophagectomy for ESCC. We calculated the ratio of the visceral fat area to the subcutaneous fat area (VS ratio), which is a valuable parameter of visceral obesity. Then, the clinicopathological characteristics were compared between patients with low VS ratio and those with high VS ratio. RESULTS: Overall and disease-specific survivals of patients with high VS ratio were significantly worse than those with low VS ratio (P < 0.001 in both). Patients with high VS ratio had considerably more advanced pN factor, higher prevalence of lymphatic invasion, and more number of metastatic lymph nodes than those with low VS ratio (P = 0.044, < 0.001, and 0.006, respectively). Among patients who received preoperative treatment, high VS ratio correlated with poor response to preoperative treatment (P = 0.040). CONCLUSIONS: Visceral obesity was associated with lymphatic invasiveness and poor response to preoperative treatment in patients with ESCC, which may negatively influence their prognosis. PMID- 29196842 TI - Involvement in care in pediatric cancer patients: implications for treatment compliance, mental health and health-related quality of life. AB - PURPOSE: The present study developed a new measure of involvement in care of pediatric oncology patients termed the Child Involvement in Care Scale (CICS), and empirically examined the mental health consequences of involvement in care for children with cancer. METHOD: The CICS was administered to 236 children with cancer aged 8-12 who were recruited from three large hospitals in Israel. The children also completed questionnaires on their mental-health symptoms and emotional well-being. The children's parents completed measures on their child's compliance with treatment and health-related quality of life (HRQOL). RESULTS: Exploratory and confirmatory factor analyses supported a 2-factor structure (knowledge and participation), representing different aspects of involvement in care. Compliance with treatment served as a mediator for the relationships between involvement in care and health-related outcomes. Involvement in care was positively associated with higher treatment compliance. In addition, treatment compliance was positively associated with HRQOL and positive emotions but negatively associated with psychiatric symptoms. CONCLUSION: Pediatric cancer patients' involvement in the process of care is linked to better treatment compliance and mental health outcomes. Additional research is needed to examine the specific conditions and contexts in which involvement in care contributes to mental health and subjective well-being of children with cancer.

AB - The original version of this article unfortunately contained mistakes in the first author's name and the running page headers. PMID- 29196843 TI - Huanglongbing Control: Perhaps the End of the Beginning. AB - Huanglongbing (HLB) is one of the most destructive citrus plant diseases worldwide. It is associated with the fastidious phloem-limited alpha proteobacteria 'Candidatus Liberibacter asiaticus', 'Ca. Liberibacter africanus' and 'Ca. Liberibacter americanus'. In recent years, HLB-associated Liberibacters have extended to North and South America. The causal agents of HLB have been putatively identified, and their transmission pathways and worldwide population structure have been extensively studied. However, very little is known about the epidemiologic relationships of Ca. L. asiaticus, which has limited the scope of HLB research and especially the development of control strategies. HLB-affected plants produce damaged fruits and die within several years. To control the disease, scientists have developed new compounds and screened existing compounds for their antibiotic and antimicrobial activities against the disease. These compounds, however, have very little or even no effect on the disease. The aim of the present review was to compile and compare different methods of HLB disease control with newly developed integrative strategies. In light of recent studies, we also describe how to control the vectors of this disease and the biological control of other citrus plant pathogens. This work could steer the attention of scientists towards integrative control strategies. PMID- 29196845 TI - Pole lengths influence O2-cost during double poling in highly trained cross country skiers. AB - PURPOSE: In elite cross-country skiing, double poling is used in different terrain. This study compared O2-cost and kinematics during double poling with four different pole lengths [self-selected (SS), SS - 5 cm, SS + 5 cm, SS + 10 cm] at Low versus Moderate incline. METHODS: Thirteen highly trained male cross country skiers (mean +/- SD 23 +/- 3 years; 182 +/- 4 cm; 77 +/- 6 kg) completed eight submaximal trials with roller skis on a treadmill at two conditions: "Low incline" (1.7 degrees ; 4.5 m s-1) and "Moderate incline" (4.5 degrees ; 2.5 m s 1) with each of the four pole lengths. O2-cost and 3D body kinematics were assessed in each trial. RESULTS: In Low incline, SS + 10 cm induced a lower O2 cost than all the other pole lengths [P < 0.05; effect size (ES) 0.5-0.8], whereas no differences were found between the remaining pole lengths (P > 0.05; ES 0.2-0.4). In Moderate incline, significant differences between all pole lengths were found for O2-cost, with SS - 5 cm > SS > SS + 5 cm > SS + 10 cm (P < 0.05; ES 0.6-1.8). The relative differences in O2-cost between SS and the other pole lengths were greater in Moderate incline than Low incline (SS - 5 cm; 1.5%, ES 0.8, SS + 5 cm; 1.3%, ES 1.0, and SS + 10 cm; 1.9%, ES 1.0, all P < 0.05). No difference was found in cycle, poling or reposition times between pole lengths. However, at both conditions a smaller total vertical displacement of center of mass was observed with SS + 10 cm compared to the other pole lengths. CONCLUSION: Increasing pole length from SS - 5 cm to SS + 10 cm during double poling induced lower O2-cost and this advantage was greater in Moderate compared to Low incline. PMID- 29196846 TI - The availability of water associated with glycogen during dehydration: a reservoir or raindrop? AB - PURPOSE: This study evaluated whether glycogen-associated water is a protected entity not subject to normal osmotic homeostasis. An investigation into practical and theoretical aspects of the functionality of this water as a determinant of osmolality, dehydration, and glycogen concentration was undertaken. METHODS: In vitro experiments were conducted to determine the intrinsic osmolality of glycogen-potassium phosphate mixtures as would be found intra-cellularly at glycogen concentrations of 2% for muscle and 5 and 10% for liver. Protected water would not be available to ionic and osmotic considerations, whereas free water would obey normal osmotic constraints. In addition, the impact of 2 L of sweat loss in situations of muscle glycogen repletion and depletion was computed to establish whether water associated with glycogen is of practical benefit (e.g., to increase "available total body water"). RESULTS: The osmolality of glycogen potassium phosphate mixtures is predictable at 2% glycogen concentration (predicted 267, measured 265.0 +/- 4.7 mOsmol kg-1) indicating that glycogen associated water is completely available to all ions and is likely part of the greater osmotic system of the body. At higher glycogen concentrations (5 and 10%), there was a small amount of glycogen water (~ 10-20%) that could be considered protected. However, the majority of the glycogen-associated water behaved to normal osmotic considerations. The theoretical exercise of selective dehydration (2 L) indicated a marginal advantage to components of total body water such as plasma volume (1.57% or 55 mL) when starting exercise glycogen replete. CONCLUSION: Glycogen-associated water does not appear to be a separate reservoir and is not able to uniquely replete water loss during dehydration. PMID- 29196847 TI - Body position influences arterial occlusion pressure: implications for the standardization of pressure during blood flow restricted exercise. AB - PURPOSE: Arterial occlusion pressure (AOP) measured in a supine position is often used to set cuff pressures for blood flow restricted exercise (BFRE). However, supine AOP may not reflect seated or standing AOP, thus potentially influencing the degree of occlusion. The primary aim of the study was to investigate the effect of body position on AOP. A secondary aim was to investigate predictors of AOP using wide and narrow cuffs. METHODS: Twenty-four subjects underwent measurements of thigh circumference, skinfold and blood pressure, followed by assessments of thigh AOP in supine and seated positions with a wide and a narrow cuff, respectively, using Doppler ultrasound. RESULTS: In the supine position, AOP was 148 +/- 19 and 348 +/- 94 mmHg with the wide and narrow cuff, respectively. This increased to 177 +/- 20 and 409 +/- 101 mmHg in the seated position, with correlations between supine and seated AOP of R 2 = 0.81 and R 2 = 0.50 for the wide and narrow cuff, respectively. For both cuff widths, thigh circumference constituted the strongest predictor of AOP, with diastolic blood pressure explaining additional variance with the wide cuff. The predictive strength of these variables did not differ between body positions. CONCLUSION: Our results indicate that body position strongly influences lower limb AOP, especially with narrow cuffs, yielding very high AOP (>= 500-600 mmHg) in some subjects. This should be taken into account in the standardization of cuff pressures used during BFRE to better control the physiological effects of BFRE. PMID- 29196848 TI - Left-sided congenital heart lesions in mosaic Turner syndrome. AB - In the era of the diseasomes and interactome networks, linking genetics with phenotypic traits in Turner syndrome should be studied thoroughly. As a part of this stratagem, mosaicism of both X and Y chromosome which is a common finding in TS and an evaluation of congenital heart diseases in the different situations of mosaic TS types, can be helpful in the identification of disturbed sex chromosomes, genes and signaling pathway actors. Here we report the case of a mosaic TS associated to four left-sided CHD, including BAV, COA, aortic aneurysms and dissections at an early age. The mosaicism included two cell lines, well defined at the cytogenetic and molecular levels: a cell line which is monosomic for Xp and Xq genes (45,X) and another which is trisomic for pseudoautosomal genes that are present on the X and Y chromosomes and escape X inactivation: 45,X[8]/46,X,idic(Y)(pter->q11.2::q11.2->pter)[42]. This case generates two hypotheses about the contribution of genes linked to the sex chromosomes and the signaling pathways involving these genes, in left-sided heart diseases. The first hypothesis suggests the interaction between X chromosome and autosomal genes or loci of aortic development, possibly dose-dependent, and which could be in the framework of TGF-beta-SMAD signaling pathways. The second implies that left-sided congenital heart lesions involve sex chromosomes loci. The reduced dosage of X chromosome gene(s), escaping X inactivation during development, contributes to this type of CHD. Regarding our case, these X chromosome genes may have homologues at the Y chromosome, but the process of inactivation of the centromeres of the isodicentric Y spreads to the concerned Y chromosome genes. Therefore, this case emerges as an invitation to consider the mosaics of Turner syndrome and to study their phenotypes in correlation with their genotypes to discover the underlying developmental and genetic mechanisms, especially the ones related to sex chromosomes. PMID- 29196851 TI - ? PMID- 29196853 TI - Immunohistochemical characterization of brush cells in the rat larynx. AB - The immunohistochemical characteristics of brush cells in the laryngeal mucosa were examined using immunohistochemistry for various immunohistochemical cell markers including villin at the light and electron microscopic levels. Cells that were immunoreactive to villin were barrel-shaped with thick cytoplasmic processes extending toward the lumen of the laryngeal cavity. Immunoelectron microscopic observations revealed thick and short microvilli with long rootlets of microfilaments. Numerous small clear vesicles and small finger-like cytoplasmic processes were observed in the apical process and lateral membrane, respectively. Double immunofluorescence showed villin-immunoreactive cells were not immunoreactive for the markers of solitary chemosensory cells, GNAT3 and phospholipase C, beta2-subunit (PLCbeta2), or for that of neuroendocrine cells, synaptosome-associated protein 25kD. Furthermore, immunoreactivities for cytokeratin 18 (CK18) and doublecortin like-kinase 1 in the perinuclear cytoplasm of villin-immunoreactive cells. However, some CK18-immunoreactive cells were immunoreactive to GNAT3 but not to villin. Regarding sensory innervation, only a few intraepithelial nerve endings with P2X3, SP, or CGRP immunoreactivity attached to villin-immunoreactive cells. In the present study, brush cells in the rat laryngeal mucosa were classified by immunoreactivity for villin, and were independent of other non-ciliated epithelial cells such as solitary chemosensory cells and neuroendocrine cells. PMID- 29196849 TI - The phenotypic and molecular assessment of the non-conserved Arabidopsis MICRORNA163/S-ADENOSYL-METHYLTRANSFERASE regulatory module during biotic stress. AB - In plants, microRNAs (miRNAs) have evolved in parallel to the protein-coding genes that they target for expression regulation, and miRNA-directed gene expression regulation is central to almost every cellular process. MicroRNA, miR163, is unique to the Arabidopsis genus and is processed into a 24-nucleotide (nt) mature small regulatory RNA (sRNA) from a single precursor transcript transcribed from a single locus, the MIR163 gene. The MIR163 locus is a result of a recent inverted duplication event of one of the five closely related S-ADENOSYL METHYLTRANSFERASE genes that the mature miR163 sRNA targets for expression regulation. Currently, however, little is known about the role of the miR163/S ADENOSYL-METHYLTRANSFERASE regulatory module in response to biotic stress. Here, we document the expression domains of MIR163 and the S-ADENOSYL-METHYLTRANSFERASE target genes following fusion of their putative promoter sequences to the beta glucuronidase (GUS) reporter gene and subsequent in planta expression. Further, we report on our phenotypic and molecular assessment of Arabidopsis thaliana plants with altered miR163 accumulation, namely the mir163-1 and mir163-2 insertion knockout mutants and the miR163 overexpression line, the MIR163-OE plant. Finally, we reveal miR163 accumulation and S-ADENOSYL-METHYLTRANSFERASE target gene expression post treatment with the defence elicitors, salicylic acid and jasmonic acid, and following Fusarium oxysporum infection, wounding, and herbivory attack. Together, the work presented here provides a comprehensive new biological insight into the role played by the Arabidopsis genus-specific miR163/S-ADENOSYL-METHYLTRANSFERASE regulatory module in normal A. thaliana development and during the exposure of A. thaliana plants to biotic stress. PMID- 29196854 TI - Fourteen years of progress testing in radiology residency training: experiences from The Netherlands. AB - OBJECTIVES: To describe the development of the Dutch Radiology Progress Test (DRPT) for knowledge testing in radiology residency training in The Netherlands from its start in 2003 up to 2016. METHODS: We reviewed all DRPTs conducted since 2003. We assessed key changes and events in the test throughout the years, as well as resident participation and dispensation for the DRPT, test reliability and discriminative power of test items. RESULTS: The DRPT has been conducted semi annually since 2003, except for 2015 when one digital DRPT failed. Key changes in these years were improvements in test analysis and feedback, test digitalization (2013) and inclusion of test items on nuclear medicine (2016). From 2003 to 2016, resident dispensation rates increased (Pearson's correlation coefficient 0.74, P value <0.01) to maximally 16 %. Cronbach's alpha for test reliability varied between 0.83 and 0.93. The percentage of DRPT test items with negative item-rest correlations, indicating relatively poor discriminative power, varied between 4 % and 11 %. CONCLUSIONS: Progress testing has proven feasible and sustainable in Dutch radiology residency training, keeping up with innovations in the radiological profession. Test reliability and discriminative power of test items have remained fair over the years, while resident dispensation rates have increased. KEY POINTS: * Progress testing allows for monitoring knowledge development from novice to senior trainee. * In postgraduate medical training, progress testing is used infrequently. * Progress testing is feasible and sustainable in radiology residency training. PMID- 29196855 TI - Ultrasound-ultrasound image overlay fusion improves real-time control of radiofrequency ablation margin in the treatment of hepatocellular carcinoma. AB - OBJECTIVES: To assess the clinical feasibility of US-US image overlay fusion with evaluation of the ablative margin in radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). METHODS: Fifty-three patients with 68 HCCs measuring 0.9-4.0 cm who underwent RFA guided by US-US overlay image fusion were included in this retrospective study. By an overlay of pre-/postoperative US, the tumor image could be projected onto the ablative hyperechoic zone. Therefore, the ablative margin three-dimensionally could be shown during the RFA procedure. US US image overlay was compared to dynamic CT a few days after RFA for assessment of early treatment response. Accuracy of graded response was calculated, and the performance of US-US image overlay fusion was compared with that of CT using a Kappa agreement test. RESULTS: Technically effective ablation was achieved in a single session, and 59 HCCs (86.8 %) succeeded in obtaining a 5-mm margin on CT. The response with US-US image overlay correctly predicted early CT evaluation with an accuracy of 92.6 % (63/68) (k = 0.67; 95 % CI: 0.39-0.95). CONCLUSION: US US image overlay fusion can be proposed as a feasible guidance in RFA with a safety margin and predicts early response of treatment assessment with high accuracy. KEY POINTS: * US-US image overlay fusion visualizes the ablative margin during RFA procedure. * Visualizing the margin during the procedure can prompt immediate complementary treatment. * US image fusion correlates with the results of early evaluation CT.

AB - OBJECTIVES: To compare a low-dose, tin-filtered, nonenhanced, high-pitch Sn100 kVp CT protocol (Sn100) with a standard protocol (STP) for the detection of calcifications in the ascending aorta in patients scheduled for cardiac surgery. METHODS: Institutional Review Board approval for this retrospective study was waived and the study was HIPAA-compliant. The study included 192 patients (128 men; age 68.8 +/- 9.9 years), of whom 87 received the STP and 105 the Sn100 protocol. Size-specific dose estimates (SSDE) and radiation doses were obtained using dose monitoring software. Two blinded readers evaluated image quality on a scale from 1 (low) to 5 (high) and the extent of calcifications of the ascending aorta on a scale from 0 (none) to 10 (high), subdivided into 12 anatomic segments. RESULTS: The Sn100 protocol achieved a mean SSDE of only 0.5 +/- 0.1 mGy and 0.20 +/- 0.04 mSv compared with the mean SSDE of 5.4 +/- 2.2 mGy achieved with the STP protocol (p < 0.0001). Calcification burden was associated with age (p < 0.0001), but was independent of protocol with mean calcification scores of 0.48 +/- 1.23 (STP) and 0.55 +/- 1.25 (Sn100, p = 0.18). Reader agreement was very good (STP kappa = 0.87 +/- 0.02, Sn100 kappa = 0.88 +/- 0.01). The STP protocol provided a higher subjective image quality than the Sn100 protocol: STP median 4, interquartile range 4-5, vs. SN100 3, 3-4; p < 0.0001) and a slightly better depiction of calcification (STP 5, 4-5, vs. Sn100 4, 4-5; p < 0.0001). CONCLUSIONS: The optimized Sn100 protocol achieved a mean SSDE of only 0.5 +/- 0.1 mGy while the depiction of calcifications remained good, and there was no systematic difference in calcification burden between the two protocols. KEY POINTS: * Tin-filtered, low-dose CT can be used to assess aortic calcifications before cardiac surgery * An optimized Sn100 protocol achieved a mean SSDE of only 0.5 +/- 0.1 mGy * The depiction of atherosclerosis of the thoracic aorta was similar with both protocols * The depiction of relevant thoracic pathologies before cardiac surgery was similar with both protocols. PMID- 29196857 TI - Pulmonary subsolid nodules: value of semi-automatic measurement in diagnostic accuracy, diagnostic reproducibility and nodule classification agreement. AB - OBJECTIVES: We hypothesized that semi-automatic diameter measurements would improve the accuracy and reproducibility in discriminating preinvasive lesions and minimally invasive adenocarcinomas from invasive pulmonary adenocarcinomas appearing as subsolid nodules (SSNs) and increase the reproducibility in classifying SSNs. METHODS: Two readers independently performed semi-automatic and manual measurements of the diameters of 102 SSNs and their solid portions. Diagnostic performance in predicting invasive adenocarcinoma based on diameters was tested using logistic regression analysis with subsequent receiver operating characteristic curves. Inter- and intrareader reproducibilities of diagnosis and SSN classification according to Fleischner's guidelines were investigated for each measurement method using Cohen's kappa statistics. RESULTS: Semi-automatic effective diameter measurements were superior to manual average diameters for the diagnosis of invasive adenocarcinoma (AUC, 0.905-0.923 for semi-automatic measurement and 0.833-0.864 for manual measurement; p<0.05). Reproducibility of diagnosis between the readers also improved with semi-automatic measurement (kappa=0.924 for semi-automatic measurement and 0.690 for manual measurement, p=0.012). Inter-reader SSN classification reproducibility was significantly higher with semi-automatic measurement (kappa=0.861 for semi-automatic measurement and 0.683 for manual measurement, p=0.022). CONCLUSIONS: Semi automatic effective diameter measurement offers an opportunity to improve diagnostic accuracy and reproducibility as well as the classification reproducibility of SSNs. KEY POINTS: * Semi-automatic effective diameter measurement improves the diagnostic accuracy for pulmonary subsolid nodules. * Semi-automatic measurement increases the inter-reader agreement on the diagnosis for subsolid nodules. * Semi-automatic measurement augments the inter-reader reproducibility for the classification of subsolid nodules. PMID- 29196859 TI - Validation of simplified postoperative nausea and vomiting intensity scale in Taiwan. AB - This study determined whether the Simplified Postoperative Nausea and Vomiting Impact Scale (SPONVIS), could be used to predict clinically important PONV in Taiwanese. In this prospective, observational study, SPONVIS, simplified Apfel PONV Risk Scores, post-operative anti-emetic drug use, total PONV score, and 3 month recall score for PONV were recorded from Taiwanese patients who had undergone general anesthesia and surgery. With antiemetic use and 3-month recall score as validations of clinical significance, we determined whether the elements and cut-off points used in the original SPONVIS study could be used in Taiwanese patients. A total of 378 patients were included in the analysis. One hundred forty (37.1%) patients had PONV. Forty-eight patients (12.7%) had clinically important PONV (SPONVIS score >= 5). The odds ratios were 14.26 (CI 6.91-29.43; P < 0.001) and 4.95 (CI 2.42 to 10.11; P < 0.001), respectively, for prediction of anti-emetic drug use and 3-month recall. The SPONVIS and its construct elements were significantly related to anti-emetic drug use, 3-month recall score for PONV, total PONV score, and Apfel risk score (all P <= 0.005), results similar to those reported in the original Australian PONV impact score study. The SPONVIS cut-off points 3 and 5 were statistically significant predictors of anti-emetic drug use. However, a cut-off point of 3 had a higher OR (24.08) than a cut-off of 5 (14.26) for prediction of anti-emetic drug use. SPONVIS and both construct elements (the nausea and vomiting impact scores) are useful predictors of clinically important PONV in Taiwanese. PMID- 29196858 TI - First Trimester Prenatal Care Initiation Among Hispanic Women Along the U.S. Mexico Border. AB - Background First trimester prenatal care (FTPNC) is associated with improved birth outcomes. U.S.-Mexico border Hispanic women have lower FTPNC than non border or non-Hispanic women. This study aimed to identify (1) what demographic, knowledge and care-seeking factors influence FTPNC among Hispanic women in border counties served by five Healthy Start sites, and (2) what FTPNC barriers may be unique to this target population. Healthy Starts work to eliminate disparities in perinatal health in areas with high poverty and poor birth outcomes. Methods 403 Hispanic women of reproductive age in border communities of California, Arizona, New Mexico and Texas were surveyed on knowledge and behaviors related to prenatal care (PNC) and basic demographic information. Chi square analyses and logistic regressions were used to identify important relationships. Results Chi square analyses revealed that primiparous women were significantly less likely to start FTPNC than multiparous women (chi2 = 6.8372, p = 0.0089). Women with accurate knowledge about FTPNC were more likely to obtain FTPNC (chi2 = 29.280, p < .001) and more likely to have seen a doctor within the past year (chi2 = 5.550, p = .018). Logistic regression confirmed that multiparity was associated with FTPNC and also that living in Texas was negatively associated with FTPNC (R2 = 0.066, F(9,340) = 2.662, p = .005). Among 27 women with non-FTPNC, barriers included late pregnancy recognition (n = 19) and no medical insurance (n = 5). Conclusions This study supports research that first time pregnancies have lower FTPNC, and demonstrated a strong association between delayed PNC and late pregnancy recognition. Strengthened investments in preconception planning could improve FTPNC in this population. PMID- 29196860 TI - Role of Thrombin in Soluble Thrombomodulin-Induced Suppression of Peripheral HMGB1-Mediated Allodynia in Mice. AB - High mobility group box 1 (HMGB1), a nuclear protein, once released into the extracellular space under pathological conditions, plays a pronociceptive role in redox-dependent distinct active forms, all-thiol HMGB1 (at-HMGB1) and disulfide HMGB1 (ds-HMGB1), that accelerate nociception through the receptor for advanced glycation endproducts (RAGE) and Toll-like receptor 4 (TLR4), respectively. Thrombomodulin (TM), an endothelial membrane protein, and soluble TM, known as TMalpha, promote thrombin-mediated activation of protein C and also sequester HMGB1, which might facilitate thrombin degradation of HMGB1. The present study aimed at clarifying the role of thrombin in TMalpha-induced suppression of peripheral HMGB1-dependent allodynia in mice. Thrombin-induced degradation of at HMGB1 and ds-HMGB1 was accelerated by TMalpha in vitro. Intraplantar (i.pl.) injection of bovine thymus-derived HMGB1 in an unknown redox state, at-HMGB1, ds HMGB1 or lipopolysaccharide (LPS), known to cause HMGB1 secretion, produced long lasting mechanical allodynia in mice, as assessed by von Frey test. TMalpha, when preadministered i.pl., prevented the allodynia caused by bovine thymus-derived HMGB1, at-HMGB1, ds-HMGB1 or LPS, in a dose-dependent manner. The TMalpha-induced suppression of the allodynia following i.pl. at-HMGB1, ds-HMGB1 or LPS was abolished by systemic preadministration of argatroban, a thrombin-inhibiting agent, and accelerated by i.pl. co-administered thrombin. Our data clearly indicate that TMalpha is capable of promoting the thrombin-induced degradation of both at-HMGB1 and ds-HMGB1, and suppresses the allodynia caused by either HMGB1 in a thrombin-dependent manner. Considering the emerging role of HMGB1 in distinct pathological pain models, the present study suggests the therapeutic usefulness of TMalpha for treatment of intractable and/or persistent pain. PMID- 29196863 TI - School Age Outcomes of Children with Autism Spectrum Disorder Who Received Community-Based Early Interventions. AB - This study followed children with Autism Spectrum Disorder (ASD) from early intervention into their early schooling years, when they were aged between 6 and 9 years, on autism symptom severity and cognitive functioning. The children, matched at pre-intervention, were compared on type of community provided service: 31 were in receipt of community-based group Early Start Denver Model and 28 had received other community provisions for ASD. Irrespective of groups, cognitive functioning was found to have significantly improved by school age compared to pre-intervention. Autism symptom severity increased during the same developmental period, seemingly driven by an increase in restricted and repetitive behaviours over time. In contrast, both groups displayed improved social affect by school age. PMID- 29196862 TI - Voluntary exposure to a toxin: the genetic influence on ethanol consumption. AB - Ethyl alcohol is a toxin that, when consumed at high levels, produces organ damage and death. One way to prevent or ameliorate this damage in humans is to reduce the exposure of organs to alcohol by reducing alcohol ingestion. Both the propensity to consume large volumes of alcohol and the susceptibility of human organs to alcohol-induced damage exhibit a strong genetic influence. We have developed an integrative genetic/genomic approach to identify transcriptional networks that predispose complex traits, including propensity for alcohol consumption and propensity for alcohol-induced organ damage. In our approach, the phenotype is assessed in a panel of recombinant inbred (RI) rat strains, and quantitative trait locus (QTL) analysis is performed. Transcriptome data from tissues/organs of naive RI rat strains are used to identify transcriptional networks using Weighted Gene Coexpression Network Analysis (WGCNA). Correlation of the first principal component of transcriptional coexpression modules with the phenotype across the rat strains, and overlap of QTLs for the phenotype and the QTLs for the coexpression modules (module eigengene QTL) provide the criteria for identification of the functionally related groups of genes that contribute to the phenotype (candidate modules). While we previously identified a brain transcriptional module whose QTL overlapped with a QTL for levels of alcohol consumption in HXB/BXH RI rat strains and 12 selected rat lines, this module did not account for all of the genetic variation in alcohol consumption. Our search for QTL overlap and correlation of coexpression modules with phenotype can, however, be applied to any organ in which the transcriptome has been measured, and this represents a holistic approach in the search for genetic contributors to complex traits. Previous work has implicated liver/brain interactions, particularly involving inflammatory/immune processes, as influencing alcohol consumption levels. We have now analyzed the liver transcriptome of the HXB/BXH RI rat panel in relation to the behavioral trait of alcohol consumption. We used RNA-Seq and microarray data to construct liver transcriptional networks, and identified a liver candidate transcriptional coexpression module that explained 24% of the genetic variance in voluntary alcohol consumption. The transcripts in this module focus attention on liver secretory products that influence inflammatory and immune signaling pathways. We propose that these liver secretory products can interact with brain mechanisms that affect alcohol consumption, and targeting these pathways provides a potential approach to reducing high levels of alcohol intake and also protecting the integrity of the liver and other organs. PMID- 29196861 TI - CRISPR-based strategies for studying regulatory elements and chromatin structure in mammalian gene control. AB - The development of high-throughput methods has enabled the genome-wide identification of putative regulatory elements in a wide variety of mammalian cells at an unprecedented resolution. Extensive genomic studies have revealed the important role of regulatory elements and genetic variation therein in disease formation and risk. In most cases, there is only correlative evidence for the roles of these elements and non-coding changes within these elements in pathogenesis. With the advent of genome- and epigenome-editing tools based on the CRISPR technology, it is now possible to test the functional relevance of the regulatory elements and alterations on a genomic scale. Here, we review the various CRISPR-based strategies that have been developed to functionally validate the candidate regulatory elements in mammals as well as the non-coding genetic variants found to be associated with human disease. We also discuss how these synthetic biology tools have helped to elucidate the role of three-dimensional nuclear architecture and higher-order chromatin organization in shaping functional genome and controlling gene expression. PMID- 29196864 TI - Choosing an Appropriate Physical Exercise to Reduce Stereotypic Behavior in Children with Autism Spectrum Disorders: A Non-randomized Crossover Study. AB - Considerable evidence has shown that physical exercise could be an effective treatment in reducing stereotypical autism spectrum disorder (ASD) behaviors in children. The present study seeks to examine the underlying mechanism by considering the theoretical operant nature of stereotypy. Children with ASD (n = 30) who exhibited hand-flapping and body-rocking stereotypies were asked to participate in both control (story-time) and experimental (ball-tapping-exercise intervention) conditions. The experimental condition comprised 15 min of ball tapping during which the children were asked to tap a plastic ball as many times as they could. Results indicated that hand-flapping stereotypy was significantly reduced but body-rocking stereotypy following the ball-tapping-exercise intervention was not. These results not only confirm the positive impact of exercise intervention on stereotypic behavior as shown in many previous studies, but further suggest that physical exercise should be matched with the biomechanics of stereotypy to produce a desirable behavioral benefit. PMID- 29196865 TI - Parent Perceptions of Psychosocial Outcomes of Equine-Assisted Interventions for Children with Autism Spectrum Disorder. AB - This research explored parents' perceptions of the psychosocial outcomes of their children's experience of receiving equine-assisted interventions (EAI). Participants were the parents of six children (aged 3-14) diagnosed with autism spectrum disorder. Five semi-structured interviews were conducted and the transcript data was analysed using Interpretative phenomenological analysis. Four super-ordinate themes emerged from the analysis: (1) child's improved self concept and enhanced emotional well-being, (2) child's improved self-regulatory ability, (3) social benefits for the child, and (4) unexpected outcomes. EAI was perceived by the parents as having several levels of psychosocial benefits for their children. These benefits may also extend to parents and family through ecopsychological and "flow on" effects associated with the children's involvement in EAI programs. PMID- 29196866 TI - Reducing Bottlenecks to Improve the Efficiency of the Lung Cancer Care Delivery Process: A Process Engineering Modeling Approach to Patient-Centered Care. AB - The process of lung cancer care from initial lesion detection to treatment is complex, involving multiple steps, each introducing the potential for substantial delays. Identifying the steps with the greatest delays enables a focused effort to improve the timeliness of care-delivery, without sacrificing quality. We retrospectively reviewed clinical events from initial detection, through histologic diagnosis, radiologic and invasive staging, and medical clearance, to surgery for all patients who had an attempted resection of a suspected lung cancer in a community healthcare system. We used a computer process modeling approach to evaluate delays in care delivery, in order to identify potential 'bottlenecks' in waiting time, the reduction of which could produce greater care efficiency. We also conducted 'what-if' analyses to predict the relative impact of simulated changes in the care delivery process to determine the most efficient pathways to surgery. The waiting time between radiologic lesion detection and diagnostic biopsy, and the waiting time from radiologic staging to surgery were the two most critical bottlenecks impeding efficient care delivery (more than 3 times larger compared to reducing other waiting times). Additionally, instituting surgical consultation prior to cardiac consultation for medical clearance and decreasing the waiting time between CT scans and diagnostic biopsies, were potentially the most impactful measures to reduce care delays before surgery. Rigorous computer simulation modeling, using clinical data, can provide useful information to identify areas for improving the efficiency of care delivery by process engineering, for patients who receive surgery for lung cancer. PMID- 29196868 TI - The proteasome and proteasome inhibitors in multiple myeloma. AB - Proteasome inhibitors are one of the most important classes of agents to have emerged for the treatment of multiple myeloma in the past two decades, and now form one of the backbones of treatment. Three agents in this class have been approved by the United States Food and Drug Administration-the first-in-class compound bortezomib, the second-generation agent carfilzomib, and the first oral proteasome inhibitor, ixazomib. The success of this class of agents is due to the exquisite sensitivity of myeloma cells to the inhibition of the 26S proteasome, which plays a critical role in the pathogenesis and proliferation of the disease. Proteasome inhibition results in multiple downstream effects, including the inhibition of NF-kappaB signaling, the accumulation of misfolded and unfolded proteins, resulting in endoplasmic reticulum stress and leading to the unfolded protein response, the downregulation of growth factor receptors, suppression of adhesion molecule expression, and inhibition of angiogenesis; resistance to proteasome inhibition may arise through cellular responses mediating these downstream effects. These multiple biologic consequences of proteasome inhibition result in synergistic or additive activity with other chemotherapeutic and targeted agents for myeloma, and proteasome inhibitor-based combination regimens have become established as a cornerstone of therapy throughout the myeloma treatment algorithm, incorporating agents from the other key classes of antimyeloma agents, including the immunomodulatory drugs, monoclonal antibodies, and histone deacetylase inhibitors. This review gives an overview of the critical role of the proteasome in myeloma and the characteristics of the different proteasome inhibitors and provides a comprehensive summary of key clinical efficacy and safety data with the currently approved proteasome inhibitors. PMID- 29196867 TI - Prevalence of haptic feedback in robot-mediated surgery: a systematic review of literature. AB - With the successful uptake and inclusion of robotic systems in minimally invasive surgery and with the increasing application of robotic surgery (RS) in numerous surgical specialities worldwide, there is now a need to develop and enhance the technology further. One such improvement is the implementation and amalgamation of haptic feedback technology into RS which will permit the operating surgeon on the console to receive haptic information on the type of tissue being operated on. The main advantage of using this is to allow the operating surgeon to feel and control the amount of force applied to different tissues during surgery thus minimising the risk of tissue damage due to both the direct and indirect effects of excessive tissue force or tension being applied during RS. We performed a two rater systematic review to identify the latest developments and potential avenues of improving technology in the application and implementation of haptic feedback technology to the operating surgeon on the console during RS. This review provides a summary of technological enhancements in RS, considering different stages of work, from proof of concept to cadaver tissue testing, surgery in animals, and finally real implementation in surgical practice. We identify that at the time of this review, while there is a unanimous agreement regarding need for haptic and tactile feedback, there are no solutions or products available that address this need. There is a scope and need for new developments in haptic augmentation for robot-mediated surgery with the aim of improving patient care and robotic surgical technology further. PMID- 29196870 TI - Changes in birth-related pain perception impact of neurobiological and psycho social factors. AB - PURPOSE: To analyse post-partum short- and long-term pain sensitivity and the influence of endogenous pain inhibition as well as distinct psycho-social factors on birth-related pain. METHODS: Pain sensitivity was assessed in 91 primiparous women at three times: 2-6 weeks before, one to 3 days as well as ten to 14 weeks after childbirth. Application of a pressure algometer in combination with a cold pressor test was utilised for measurement of pain sensitivity and assessment of conditioned pain modulation (CPM). Selected psycho-social factors (anxiety, social support, history of abuse, chronic pain and fear of childbirth) were evaluated with standardised questionnaires and their effect on pain processing then analysed. RESULTS: Pressure pain threshold, cold pain threshold and cold pain tolerance increased significantly directly after birth (all p < 0.001). While cold pain parameters partly recovered on follow-up, pressure pain threshold remained increased above baseline (p < 0.001). These pain-modulating effects were not found for women with history of abuse. While CPM was not affected by birth, its extent correlated significantly (r = 0.367) with the drop in pain sensitivity following birth. Moreover, high trait anxiety predicted an attenuated reduction in pain sensitivity (r = 0.357), while there was no correlation with fear of childbirth, chronic pain and social support. CONCLUSION: Pain sensitivity showed a decrease when comparing post-partum with prepartum values. The extent and direction of CPM appear to be a trait variable that predicted post-partum hypalgesia without being changed itself. Post-partum hypalgesia was reduced in women with a history of abuse and high trait anxiety, which suggests that individual differences in CPM affect childbirth experience. PMID- 29196869 TI - Circulating levels of specific members of chromosome 19 microRNA cluster are associated with preeclampsia development. AB - PURPOSE: To perform serum microRNA expression profiling to identify members of chromosome 19 miRNA cluster involved in preeclampsia development. METHODS: Serum chromosome 19 miRNA cluster microRNA expression profiling was evaluated at 12, 16, and 20 gestational weeks and at the time of preeclampsia diagnosis, in women who developed preeclampsia (WWD-PE; n = 16) and controls (n = 18) using TaqMan low density array plates. RESULTS: A total of 51 chromosome 19 microRNA cluster members were evaluated. The circulating hsa-miRs 512-3p, 518f-3p, 520c-3p, and 520d-3p, were differentially expressed between groups (P < 0.05). Compared with controls, serum levels of hsa-miR-518f-3p at 20 GW were useful for identifying WWD-Mild-PE (P = 0.035) and WWD-Severe-PE (P = 0.007). CONCLUSIONS: Serum hsa miRs 512-3p, 518f-3p, 520c-3p, and 520d-3p, are differentially expressed between WWD-PE and controls and their role in the development of preeclampsia should be investigated further. PMID- 29196871 TI - Three cases of metallosis associated with spine instrumentation. AB - The characteristic trait of metallosis is the presence of tissue staining. Analyzing explanted revision hardware from spine surgeries and performing ICPMS/AES analysis on removed tissue samples, a clinically relevant definition for metallosis may be developed. Results of the analysis identified hardware fretting wear and corrosion, and ICP-MS/AES analysis identified elevated metal ion concentrations in all cases. This supports the hypothesis that corrosion may be linked to poor health outcomes and potential need for revision surgery. Using failure analysis methods, corrosion products from orthopedic spine implants can be identified to begin to characterize metallosis in a clinically relevant manner. Failure analysis for patients undergoing revision spine surgery for other causes. Using failure analysis methods we conducted a retrieval analysis of explanted hardware and tissue. Implant failure with surrounding tissue metal staining is a current issue in the field of orthopedics. Specifically in spine, this issue is under reported and over looked as a clinically significant finding. Metallosis is most commonly used to describe the presence of tissue staining however this is not a clinically relevant definition. There is a need for further research to provide a better understanding of metallosis leading to better patient outcomes. Patients were screened for this study during a radiological review prior to surgery. All explanted hardware was documented and inspected for signs of wear and corrosion using non-destructive testing. A tissue sample that is normally removed and discarded was collected for ICP-MS/AES analysis. The presence of fretting corrosion, galling and corrosion fatigue was found on all explanted hardware. Cr levels are significantly higher than what was previously published as normal in muscle 0.03 MUg/g. One case was a 4 order of magnitude elevation with the other 2 approximately 2 orders of magnitude increase. Titanium and Co concentrations are also significantly increased. The Ca to P ratio for all samples is approximately 1.7:1 suggesting some form of apatitic crystal present due to drying of the tissues. In all cases, the Al, Mo, V, Co, content in surrounding tissue is significantly elevated >10* above "normal," 8.4 +/- 4.8; 1.61 +/- 1.41; 0.06 +/- 0.03; 1.35 +/- 1.97 MUg/g respectively. A "normal" reference titanium level could only be found for whole blood, 0.00072 +/- 0.1412 MU/g. Iron and Ni measurements are within typical values presented in previous studies. No single mechanism for the release of metal ion in a patient is clear. Evidence suggests a tribocorrosive process due to both wear and environmental factors. Specific biologic mechanisms, such as the possible presence of bacteria may affect the fretting and corrosion of spinal instrumentation must be explored in conjunction with thorough review of patient outcomes. Such an effort can potentially reduce patient readmission and increase successful patient outcomes. PMID- 29196872 TI - Seleno-compounds and Carnosic Acid Added to Diets with Rapeseed and Fish Oils Affect Concentrations of Selected Elements and Chemical Composition in the Liver, Heart and Muscles of Lambs. AB - The objective of our studies was to investigate effects of carnosic acid (CA), selenized yeast (SeY) and selenate (SeVI) added to the diet including rapeseed oil (RO) and fish oil (FO) on concentrations of elements, fatty acids (FAs), tocopherols, cholesterol, and malondialdehyde in the liver, heart, musculus longissimus dorsi (MLD), and musculus biceps femoris (MBF) of lambs. Lambs were fed diets: group I-the basal diet (BD) with RO; group II-BD with RO and FO; group III-BD with RO, FO, and CA; group IV-BD with RO, FO, CA, and SeY; group V-BD with RO, FO, CA, and SeVI. The diets with Se compounds increased Se concentrations in all tissues compared with other diets. The diet with SeVI increased Cd, Sb, and Pb concentrations in the liver compared to groups I, II, and IV. The diets containing Se compounds increased Sb and Pb concentrations in MBF compared to groups I and II. All diets with CA reduced As, Sb, and Pb concentrations in MLD compared to groups I and II. All diets with FO increased concentrations of FAs and malondialdehyde in the liver compared to group I. All diets with FO decreased FAs concentrations in MBF compared to group I. The diets containing CA with/without Se compounds increased malondialdehyde concentrations in MBF compared to groups I and II. The diet with Se compounds reduced malondialdehyde concentrations in MLD compared to group II. All diets with FO changed concentrations of tocopherols and cholesterol in all tissues compared to group I. Our study showed that the addition of SeY or SeVI to the experimental diet increased the concentration of Se in all assayed tissues of lambs without adversely influencing performance or causing physiological disorders in internal organs. Both, SeY or SeVI added to the experimental diet decreased the oxidative stress and the concentrations of As, Sb, and Pb in MLD compared with the diets containing RO, irrespective of the presence of FO (groups I and II). Our study provides useful knowledge for nutritionists carrying out further investigations aimed at improving farm animal health, performance, and the nutritional quality of animal products for humans. PMID- 29196873 TI - Total Mercury Determination in Muscle and Liver Tissue Samples from Brazilian Amazon Fish Using Slurry Sampling. AB - This paper presents a slurry sampling method for total mercury determination by graphite furnace atomic absorption spectrometry (GFAAS) in tissue of fish from the Amazon. The tissue samples were lyophilized and macerated, and then the slurry samples were prepared by putting 20 mg of tissue, added to a solution containing Triton X-100, Suprapur HNO3, and zirconium nitrate directly in sampling vials of a spectrometer. Mercury standard solutions were prepared under the same conditions as the slurry samples. The slurry samples and the mercury standard solutions were sonicated for 20 s. Twenty microliters of slurry samples were injected into the graphite tube, which contained an internal wall lined with tungsten carbide. Under these conditions, it was possible to thermally stabilize the mercury up to an atomization temperature of 1700 degrees C. The method was validated by mercury determination in reference materials DORM-4 and DOLT-4. The LOD and LOQ were 0.014 and 0.045 mg kg-1, respectively, and recovery percentages in relation to the concentration values were certified in the order of 98%.

AB - Voltage-dependent anion channel 1 (VDAC1) is thought to contribute to the progression of tumor development. However, whether VDAC1 contributes to bone cancer pain remains unknown. In this study, we found that the expression of VDAC1 was upregulated in the L2-5 segments of the spinal dorsal horn at 2 and 3 weeks after injection of tumor cells into the tibial cavity. Intrathecal injection of a VDAC1 inhibitor significantly reversed the pain hypersensitivity and reduced the over-expression of Toll-like receptor 4 (TLR4). Intrathecal injection of minocycline, an inhibitor of microglia, also attenuated the pain hypersensitivity of rat models of bone cancer pain. These results suggest that VDAC1 plays a significant role in the development of complicated cancer pain, possibly by regulating the expression of TLR4. PMID- 29196876 TI - Early recognition of sudden cardiac arrest in athletes during sports activity. AB - INTRODUCTION: Sudden cardiac arrest (SCA) in athletes is an unexpected life threatening event, which is often not recognised early and cardiopulmonary resuscitation (CPR) is not always initiated immediately. We describe key features to rapidly recognise non-traumatic SCA in athletes during sports activity. METHODS: We reviewed videos and images of athletes suffering from non-traumatic SCA during sports activity. We searched Google images, Google videos and YouTube.com using the keywords 'sudden cardiac death athlete' and 'resuscitation athlete'. We analysed (1) the athlete's performance before syncope, (2) the athlete's performance at the start of syncope, (3) the position of the body, and (4) the athlete's facial expressions before CPR. We analysed our data by describing these four features to answer our research question. RESULTS: We analysed the sequence of events in six well-known soccer players in whom a camera witnessed non-traumatic SCA occurred during their athletic activity. All six athletes showed no changes before syncope. Four became unstable while standing and unexpectedly collapsed falling on their back. Two suddenly 'dropped dead' and fell face down. All six had their eyes wide open with a fixed gaze and fixed pupils. CONCLUSIONS: Sudden unexpected loss of consciousness in an athlete in action and a fixed gaze eye position are key features of SCA. Immediate cardiac massage should follow. The described features to immediately recognise SCA in athletes during sports activity should be taught to everyone involved in athletic activity leading to earlier recognition of SCA followed by earlier CPR. PMID- 29196877 TI - Gold open access: the best of both worlds. AB - Gold open access provides free distribution of trustworthy scientific knowledge for everyone. As publication modus, it has to withstand the bad reputation of predatory journals and overcome the preconceptions of those who believe that open access is synonymous with poor quality articles and high costs. Gold open access has a bright future and will serve the scientific community, clinicians without academic affiliations and the general public. PMID- 29196878 TI - Gut microbiome production of short-chain fatty acids and obesity in children. AB - Obesity has been a worldwide multifactorial epidemic malady for the last 2 decades. Changes in gut microbiota composition and its metabolites - short-chain fatty acids (SCFAs) - have been associated with obesity. Recent evidence suggests that SCFAs made by the gut microbiota may regulate directly or indirectly physiological and pathological processes in relation to obesity. We review the influence of gut microbiota in energy, glucose, and lipid homeostasis control via their metabolites. Gut microbial disturbances in obese children may have a role in their metabolism. At first glance, excessive short-chain fatty acids produced by a particular gut microbiota represent an additional energy source, and should cause an imbalance in energy regulation, contributing to obesity. However, simultaneously, SCFA participates in glucose-stimulated insulin secretion from the pancreatic beta-cells through interaction with the FFA2 and FFA3 receptors, and release of peptide hormones which control appetite. This apparent contradictory situation may indicate the involvement of additional particular bacteria or bacterial components or metabolites that may trigger regulatory cascades by interaction with some G-protein-coupled membrane receptors.

AB - In forensic medicine, expert opinion is often required concerning dose and time of intake of a substance, especially in the context of fatal intoxications. In the present case, a 98-year-old man died 4 days after admission to a hospital due to a femur neck fracture following a domestic fall in his retirement home. As he had obtained high morphine doses in the context of palliative therapy and a confusion of his supplemental magnesium tablets with a diuretic by the care retirement home was suspected by the relatives, a comprehensive postmortem examination was performed. Forensic toxicological GC- and LC-MS analyses revealed, besides propofol, ketamine, and a metamizole metabolite in blood and urine, toxic blood morphine concentrations of approximately 3 mg/l in femoral and 5 mg/l in heart blood as well as 2, 7, and 10 mg/kg morphine in brain, liver, and lung, respectively. A physiologically based pharmacokinetic (PBPK) model was developed and applied to examine whether the morphine concentrations were (i) in agreement with the morphine doses documented in the clinical records or (ii) due to an excessive morphine administration. PBPK model simulations argue against an overdosing of morphine. The immediate cause of death was respiratory and cardiovascular failure due to pneumonia following a fall, femur neck fracture, and immobilization accompanied by a high and probably toxic concentration of morphine, attributable to the administration under palliative care conditions. The presented case indicates that PBPK modeling can be a useful tool in forensic medicine, especially in question of a possible drug overdosing.

AB - BACKGROUND: Necrotizing enterocolitis (NEC) is a gastrointestinal disease of complex etiology resulting in devastating systemic inflammation and often death in premature newborns. We previously demonstrated that formula feeding inhibits ileal expression of heat shock protein-70 (Hsp70), a critical stress protein within the intestine. Barrier function for the premature intestine is critical. We sought to determine whether reduced Hsp70 protein expression increases neonatal intestinal permeability. METHODS: Young adult mouse colon cells (YAMC) were utilized to evaluate barrier function as well as intestine from Hsp70-/- pups (KO). Sections of intestine were analyzed by Western blot, immunohistochemistry, and real time PCR. YAMC cells were sub-lethally heated or treated with expressed milk (EM) to induce Hsp70. RESULTS: Immunostaining demonstrates co-localized Hsp70 and tight junction protein zona occludens-1 (ZO 1), suggesting physical interaction to protect tight junction function. The permeability of YAMC monolayers increases following oxidant injury and is partially blocked by Hsp70 induction either by prior heat stress or EM. RT-PCR analysis demonstrated that the Hsp70 isoforms, 70.1 and 70.3, predominate in WT pup; however, Hsp70.2 predominates in the KO pups. While Hsp70 is present in WT milk, it is not present in KO EM. Hsp70 associates with ZO-1 to maintain epithelial barrier function. CONCLUSION: Both induction of Hsp70 and exposure to EM prevent stress-induced increased permeability. Hsp70.2 is present in both WT and KO neonatal intestine, suggesting a crucial role in epithelial integrity. Induction of the Hsp70.2 isoform appears to be mediated by mother's milk. These results suggest that mother's milk feeding modulates Hsp70.2 expression and could attenuate injury leading to NEC. LEVEL OF EVIDENCE: Level III. PMID- 29196881 TI - Gata-6 expression is decreased in diaphragmatic and pulmonary mesenchyme of fetal rats with nitrofen-induced congenital diaphragmatic hernia. AB - PURPOSE: Congenital diaphragmatic hernia (CDH) and associated pulmonary hypoplasia are thought to be caused by a malformation of the underlying diaphragmatic and airway mesenchyme. GATA binding protein 6 (Gata-6) is a zinc finger-containing transcription factor that plays a crucial role during diaphragm and lung development. In the primordial diaphragm, Gata-6 expression is restricted to mesenchymal compartments of the pleuroperitoneal folds (PPFs). In addition, Gata-6 is essential for airway branching morphogenesis through upregulation of mesenchymal signaling. Recently, mutations in Gata-6 have been linked to human CDH. We hypothesized that diaphragmatic and pulmonary Gata-6 expression is decreased in the nitrofen-induced CDH model. METHODS: Time-mated rats were exposed to either nitrofen or vehicle on gestational day 9 (D9). Fetal diaphragms (n = 72) and lungs (n = 48) were microdissected on selected timepoints D13, D15 and D18, and divided into control and nitrofen-exposed specimens (n = 12 per sample, timepoint and experimental group, respectively). Diaphragmatic and pulmonary gene expression of Gata-6 was analyzed by qRT-PCR. Immunofluorescence double staining for Gata-6 was combined with the diaphragmatic mesenchymal marker Gata-4 and the pulmonary mesenchymal marker Fgf-10 to evaluate protein expression and localization in fetal diaphragms and lungs. RESULTS: Relative mRNA expression levels of Gata-6 were significantly decreased in PPFs on D13 (0.57 +/- 0.21 vs. 2.27 +/- 1.30; p < 0.05), developing diaphragms (0.94 +/- 0.59 vs. 2.28 +/- 1.89; p < 0.05) and lungs (0.56 +/- 0.16 vs. 0.71 +/- 0.39; p < 0.05) on D15 and fully muscularized diaphragms (1.20 +/- 1.10 vs. 2.52 +/- 1.86; p < 0.05) and differentiated lungs (0.56 +/- 0.05 vs. 0.77 +/- 0.14; p < 0.05) on D18 of nitrofen-exposed fetuses compared to controls. Confocal laser scanning microscopy demonstrated markedly diminished immunofluorescence of Gata-6 mainly in diaphragmatic and pulmonary mesenchyme, which was associated with a reduction of proliferating mesenchymal cells in nitrofen-exposed fetuses on D13, D15, and D18 compared to controls. CONCLUSION: Decreased Gata-6 expression during diaphragmatic development and lung branching morphogenesis may disrupt mesenchymal cell proliferation, causing malformed PPFs and reduced airway branching, thus leading to diaphragmatic defects and pulmonary hypoplasia in the nitrofen-induced CDH model. PMID- 29196882 TI - The GABRB3 Polymorphism and its Association with Schizophrenia. AB - The aim of this study was to explore whether schizophrenia occurrence is associated with polymorphisms in the 5' regulatory region of GABRB3 (gamma aminobutyric acid type A receptor beta 3, subunit gene). The study included 324 patients with schizophrenia and 327 unaffected participants; all individuals were northern Han Chinese. Genotype and haplotype frequency distributions were compared for the 2 groups by means of PCR amplification and direct sequencing of the promoter region of GABRB3. The genotype distribution among control participants was in accordance with the Hardy-Weinberg equilibrium. Five common single-nucleotide polymorphism (SNP) sites were detected in the 5' promoter region of GABRB3: rs4243768, rs7171660, rs4363842, rs4906902, and rs8179184. Only rs8179184 and rs4906902 differed significantly in frequency between controls and cases (P < 0.05); this difference remained significant when only women in each group were compared. The 2 SNP sites showed linkage disequilibrium, resulting in 2 haplotypes: T-G and C-A. The frequency of C-A was significantly higher among patients with schizophrenia than among controls. Our findings suggest that rs4906902 and rs8179184 in the 5' promoter region of GABRB3 are associated with schizophrenia. The C-A haplotype may entail an increased risk of schizophrenia, and the onset of schizophrenia may be gender-specific. PMID- 29196883 TI - Magnesium Lithospermate B Suppresses Lipopolysaccharide-Induced Neuroinflammation in BV2 Microglial Cells and Attenuates Neurodegeneration in Lipopolysaccharide Injected Mice. AB - Chronic inflammation in the brain plays a critical role in major neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), and multiple sclerosis (MS). Microglia, the resident macrophages and intrinsic components of the central nervous system (CNS), appear to be the main effectors in this pathological process. Magnesium lithospermate B (MLB) is one of the major bioactive components of Radix Salviae miltiorrhizae, which has been documented to protect neurons against multiple types of neuronal injury. However, its functions on microglia and the related neuroinflammation remain unknown. In the present study, BV2 microglial cells were used to assess the anti neuroinflammatory capacity of MLB. Our data show that treatment with MLB could not only suppress lipopolysaccharide (LPS)-induced proliferation and morphological changes, but also interfere with cell cycle progression in BV2 cells. More strikingly, it attenuated the production of the inflammatory mediator nitric oxide (NO) and a panel of pro-inflammatory cytokine in LPS-stimulated BV2 cells, including tumor necrosis factor-alpha (TNF-alpha), interleukin (IL) 1alpha, IL-1beta, and IL-6, and also promoted a phenotypic switch from the M1 to the M2 phenotype. Additionally, an in vivo study showed that the administration of MLB could ameliorate lipopolysaccharide-induced neurodegeneration and microglial activation in the hippocampus of adult mice. Mechanistically, MLB blocked the activation of the NF-kappaB pathway upon LPS stimulation, indicating that the effects of MLB on microglia may be mediated by the NK-kappaB pathway. These results suggest the therapeutic potential of MLB as a novel anti inflammatory and microglia-modulating drug for neurodegenerative diseases. PMID- 29196885 TI - Section 11: Poster Sessions.

PMID- 29196884 TI - Ultrasonographical Features Associated with Progression of Atherosclerosis in Patients with Moderate Internal Carotid Artery Stenosis. AB - Carotid artery stenosis (CAS) is a leading cause of ischemic stroke. Plaque stabilization is a major management approach. Information about the ultrasonographical and clinical features associated with the progression of moderate internal carotid artery (ICA) stenosis (50-69%) could assist with prognostication and risk factor modifications. We evaluated 287 patients with moderate ICA stenosis (50-69%) and subsequently evaluated them at follow-up points at 12, 24, and 36 months. Patients were divided into three groups according to the degree of ICA stenosis: progression (70-99%, n = 48), stable (50 69%, n = 210), and regression (< 50%, n = 29). Responsible plaque thickness (RPT) across groups during follow-up was compared using a repeated measure ANOVA test. An ordinal regression was subsequently applied to identify risk factors for atherosclerosis progression. Male (P = 0.04), hypoechoic plaque (P < 0.01), smoking (P = 0.02), plaque ulceration (P = 0.05), and contralateral severe CAS or occlusions (P = 0.04) on ultrasound was more frequent in the progression group vs. other two groups. The ordinal regression revealed that only hypoechoic plaque (OR, 7.03; 95% CI, 3.34-14.81; P < 0.01) and contralateral ICA severe stenosis or occlusion (OR, 2.86; 95% CI, 1.41-5.80; P < 0.01) were independently associated with stenosis progression, while statin use was inversely associated with stenosis progression (OR, 0.26; 95% CI, 0.13-0.54; P < 0.01). Of note, symptomatic vs. asymptomatic moderate CAS at baseline was not associated with progression. For patients with moderate CAS, hypoechoic plaque, contralateral severe stenosis or occlusion on ultrasonography, and statin use are independently related to stenosis progression. Statin use may delay the progression of carotid stenosis. PMID- 29196888 TI - Evolving the Urban Health Agenda. PMID- 29196889 TI - Durable Resolution of Severe Psoriasis in a Patient Treated with Pentostatin for Hairy Cell Leukemia: A Case Report. AB - INTRODUCTION: Pentostatin (2'-deoxycoformycin) and cladribine (2 chlorodeoxyadenosine) are adenosine analogues widely used to treat lymphoid malignancies, mainly hairy cell leukemia (HCL). Oral or parenteral adenosine analogues have been also used as immunomodulatory agents in multiple sclerosis and in acute graft-versus-host disease. CASE REPORT: Here, we report the case of a 43-year-old patient with a history of extensive psoriasis who later developed HCL. RESULTS: The patient had achieved complete remission of both psoriasis and HCL after receiving intravenous infusions of pentostatin. It is worth noting that cladribine has already been reported to treat plaque psoriasis lesions in two patients with HCL and in a third patient with gastric marginal zone B cell lymphoma [1]. CONCLUSION: We believe that adenosine analogues constitute a promising therapeutic option for moderate to severe psoriasis, especially for severe and refractory psoriasis, as well as for patients with adjacent lymphoid malignancies. PMID- 29196891 TI - Sodium valproate modulates immune response by alternative activation of monocyte derived macrophages in systemic lupus erythematosus. AB - The anti-inflammatory role of macrophages in apoptotic cells (ACs) clearance is involved in Systemic Lupus Erythematosus (SLE) pathogenesis. The efferocytic capability of macrophages is altered by M1/M2 polarization. Histone deacetylase inhibitors (HDACi) are proposed to enhance the expansion of M2 macrophages. Sodium valproate (VPA) is an HDACi with different anti-inflammatory properties. Here, we aimed to investigate the effects of HDACi by VPA on the polarization of monocyte-derived macrophages (MDMs) and regulating the expression of anti inflammatory cytokines in SLE. We studied the ex vivo alterations of MDMs among 15 newly diagnosed SLE patients and 10 normal subjects followed by ACs and VPA treatments. M1/M2 polarization was assessed by expression of CD86/CD163, IL1 beta, IDO-1, and MRC-1 among treated and non-treated MDMs. We also evaluated the production of IL-10, IL-12, TGF-beta1, and TNF-alpha cytokines in the cell culture supernatants. CD163 was overexpressed upon VPA treatment, while CD86 showed no significant change. IL1-beta and IDO-1 genes were significantly downregulated, and the mRNA expression of MRC-1 was increased among VPA-treated MDMs of SLE patients. The anti-inflammatory cytokines (IL-10 and TGF-beta1) were overproduced while TNF-alpha level was decreased in response to VPA. The population of classically activated macrophages was more prevalent among SLE patients and efferocytosis was defected. VPA could successfully enhance the anti inflammatory immune response through alternative activation of MDMs in SLE patients. PMID- 29196890 TI - Malnutrition and sarcopenia in a large cohort of patients with systemic sclerosis. AB - Systemic sclerosis (SSc) is an autoimmune disease which may lead to malnutrition. Previous studies have defined it with different criteria. No thorough evaluations of sarcopenia in SSc are available. The aim of the present study was to assess the prevalence and the potential association of malnutrition and sarcopenia in a large cohort of SSc cases. A total of 141 SSc consecutive outpatients were enrolled. Body composition was analyzed by densitometry. Malnutrition was defined according to recently published ESPEN criteria, whereas sarcopenia was diagnosed in patients with reduced skeletal muscle index. Malnutrition was diagnosed in 9.2% of patients (95% CI, 4.4-14.0%). Malnourished patients had worse gastrointestinal symptoms according to UCLA SCTC GIT 2.0 questionnaire (p = 0.007), lower physical activity (p = 0.028), longer disease duration (p = 0.019), worse predicted DLCO/VA and FVC (p = 0.009, respectively), worse disease severity according to Medsger severity score (p < 0.001), lower hemoglobin (p = 0.023), and fat-free mass (p < 0.001) and were more often sarcopenic (p < 0.001). In multivariate analysis, only FVC (p = 0.006) and disease severity (p = 0.003), in particular for the lungs (p = 0.013), were confirmed to be worse in malnourished patients. Sarcopenia was diagnosed in 29?140 patients (20.7%; 95% CI, 14.0 27.4%); 11?29 were also malnourished. In multivariate analysis, sarcopenic patients had longer disease duration (p = 0.049), worse DLCO/VA (p = 0.002), and lung (p = 0.006) and skin (p = 0.014) involvement. In SSc, malnutrition defined with ESPEN criteria was found to be lower than previously reported. Sarcopenia was found to be somewhat common. Lung involvement was significantly associated with nutritional status and may not be explained only by muscle weakness. PMID- 29196892 TI - Rates of and methods used at reoperation for recurrence after primary inguinal hernia repair with Prolene Hernia System and Lichtenstein. AB - INTRODUCTION: Since the introduction of tension-free mesh repair of inguinal hernia ad modum Lichtenstein (L), recurrence rates have been reduced to 1-2%. The bi-layer mesh Prolene Hernia System (PHS) is an alternative mesh with a theoretical potential to further reduce recurrence rates. However, a reoperation due to recurrence after PHS might be technically difficult since both the anterior and posterior space has been utilized. METHODS: Data on all males 18-75 years undergoing primary inguinal hernia repair (IHR) with PHS or L between January 1999 and October 2010 was collected from the Swedish Hernia Register (SHR). Moreover, data was collected for all operations due to recurrence after primary IHR with PHS or L between January 1st 1999 and December 31st 2014. RESULTS: A total of 1229 primary IHR with PHS and 78,230 with L was identified. Rates of reoperation for recurrence after PHS was significantly lower compared to L (1.5 vs. 2.7 %), [OR 0.38 (0.20-0.74)]. A medial recurrence was most common in both groups. At reoperation, an open anterior mesh repair was used in 74 % after PHS and a posterior mesh repair was performed in 58 % after L. Re-operating time was shorter, although not statistically significant in the PHS group (47 vs. 58 min, p = 0.29). Complication rates after surgery due to recurrence did not differ between groups. CONCLUSION: The findings from this dataset suggest that recurrence rates after primary IHR with PHS might be lower and that reoperation due to recurrence after PHS is not more complicated than after L. PMID- 29196893 TI - High yield production of four-carbon dicarboxylic acids by metabolically engineered Escherichia coli. AB - Several metabolic engineered Escherichia coli strains were constructed and evaluated for four-carbon dicarboxylic acid production. Fumarase A, fumarase B and fumarase C single, double and triple mutants were constructed in a ldhA adhE mutant background overexpressing the pyruvate carboxylase from Lactococcus lactis. All the mutants produced succinate as the main four-carbon (C4) dicarboxylic acid product when glucose was used as carbon source with the exception of the fumAC and the triple fumB fumAC deletion strains, where malate was the main C4-product with a yield of 0.61-0.67 mol (mole glucose)-1. Additionally, a mdh mutant strain and a previously engineered high-succinate producing strain (SBS550MG-Cms pHL413-Km) were investigated for aerobic malate production from succinate. These strains produced 40.38 mM (5.41 g/L) and 50.34 mM (6.75 g/L) malate with a molar yield of 0.53 and 0.55 mol (mole succinate)-1, respectively. Finally, by exploiting the high-succinate production capability, the strain SBS550MG-Cms243 pHL413-Km showed significant malate production in a two-stage process from glucose. This strain produced 133 mM (17.83 g/L) malate in 47 h, with a high yield of 1.3 mol (mole glucose)-1 and productivity of 0.38 g L 1 h-1.

PMID- 29196895 TI - Targeted Proteomics Driven Verification of Biomarker Candidates Associated with Breast Cancer Aggressiveness. AB - Breast cancer is the most common and molecularly well-characterized malignant cancer in women; however, its progression to metastatic cancer remains lethal for 78% of patients within 5 years of diagnosis. Identifying novel markers in high risk patients using quantitative methods is essential to overcome genetic, inter tumor, and intra-tumor variability, and to translate novel findings into cancer diagnosis and treatment. Using untargeted proteomics, we recently identified 13 proteins associated with some key factors of breast cancer aggressiveness: estrogen receptors, tumor grade, and lymph node status. Here we verified these findings in a set of 96 tumors using targeted proteomics based on selected reaction monitoring with mTRAQ labeling (mTRAQ-SRM). This study highlights a panel of gene products that could contribute to breast cancer aggressiveness and metastasis, and can help develop more precise breast cancer treatments.

AB - Measuring fluorescence is a noninvasive, inexpensive, and quick way of determining biomass concentration and health of the algae. Fluorescence is generally positively correlated with chlorophyll a and can as such be used as a proxy for biomass. In addition, the proportion variable fluorescence of maximal fluorescence is a measure of photochemical efficiency, which is affected by stress in a very early stage and can as such be used as a proxy for algal health. PMID- 29196897 TI - Fractionation of Soluble Proteins Using DEAE-Sepharose, SP-Sepharose, and Phenyl Sepharose Chromatographies for Proteomics. AB - In order to simplify a complex mixture of soluble proteins from tissues, a protocol to fractionate samples prior to two-dimensional (2D) gel electrophoresis has been developed. These methods involve the use of DEAE-Sepharose, SP Sepharose, and phenyl Sepharose chromatographic columns and the fractionation of the protein mixtures based on differential anionic, cationic, and hydrophobic properties of the proteins, respectively. Fractionation of the soluble proteins with DEAE-Sepharose can result in an increase in the number of detectable 2D gel spots. These gel spots are amenable to protein identification by using in-gel trypsin digestions, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, and peptide mass fingerprinting. The DEAE-Sepharose column fractionation acts to partition soluble proteins from cell extracts. Similarly, a SP-Sepharose column can fractionate soluble proteins and increase the number of detectable gel spots. Lastly, fractionation of cell extract with a phenyl Sepharose column can also result in an increase in the number of detectable 2D gel spots. This chapter describes an easy, inexpensive way to fractionate soluble proteins and a way to better profile proteomes. PMID- 29196898 TI - Fabrication of curcumin-loaded electrospun nanofiberous polyurethanes with anti bacterial activity. AB - Two series of polyurethane (PU), based on polycaprolactone (PCL) as soft segments with two different molecular weights (2000 and 530 Da), and hexamethylene diisocyanate (HDI) and 1,4-butandiol (BDO) as hard segments were synthesized to fabricate curcumin-loaded electrospun nanofibrous PCL-based PU substrate. Chemical structures of the synthesized PUs were characterized by FTIR and NMR spectroscopy techniques. The thermal properties were analyzed by differential scanning calorimetry (DSC) and surface hydrophilicity was studied by static contact angle and bulk hydrophilicity was evaluated by water uptake test. Thereafter, bead-free PU nanofiberous substrate containing curcumin was fabricated by electrospinning and morphology of the mats was observed by scanning electron microscopy (SEM). Mechanical properties of the electrospun mats in comparison with polymeric films were assessed by a universal test machine. The in vitro release of curcumin was studied by UV-Vis spectroscopy. The optical density of the bacterial solutions was used to evaluate the antibacterial activity of the curcumin-loaded nanofibrous mats against Escherichia coli (E-coli ATCC: 25922). The results showed that curcumin-loaded PU synthesized by PCL with molecular weight of 2000 Da displayed better mechanical properties as well as better antibacterial properties in wound dressing application. PMID- 29196899 TI - Trends in the Perpetration of Physical Aggression among Norwegian Adolescents 2007-2015. AB - Most research on trends in physical aggression has shown declining levels among adolescents during the past two decades. However, few studies have attempted to explain such time trends. Based on two representative cross-sectional surveys of students in the final year of high school in 2007 (N = 6631; 58.8% girls) and 2015 (N = 4145; 60.3% girls), this study reports a substantial decline in physical aggression among Norwegian adolescents. Moreover, mediation analyses show that declining levels in problematic alcohol use and family violence during the same period are plausible explanations for some of this reduction. The results are discussed in light of contemporary changes in socialization of adolescents, and implications for violence prevention are presented. PMID- 29196900 TI - Novel poss reinforced chitosan composite membranes for guided bone tissue regeneration. AB - In this study, novel composites membranes composed of chitosan matrix and polyhedral oligomeric silsesquioxanes (POSS) were fabricated by solvent casting method. The effect of POSS loading on the mechanical, morphological, chemical, thermal and surface properties, and cytocompatibility of composite membranes were investigated and observed by tensile test, atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA), protein adsorption assay, air/water contact angle analysis and WST-1 respectively. Swelling studies were also performed by water absorption capacity determination. Results showed that incorporation of Octa-TMA POSS(r) nanofiller to the chitosan matrix increased the surface roughness, protein adsorption and swelling capacity of membranes. The addition of POSS enhanced significantly the ultimate tensile strength and strain at break of the composite membranes up to 3 wt% POSS loaded samples. An increase of about 76% in tensile strength and of strain at break 1.28% was achieved for 3 wt% POSS loaded nanocomposite membranes compared with chitosan membranes. The presence of POSS filler into polymer matrix increased the plasma protein adsorption on the surface. Maximum protein capacity and swelling was obtained for 10 wt% loaded samples. High cell viability results were obtained with indirect extraction of chitosan/POSS composites. Besides, cell proliferation and ALP activity results showed that POSS incorporation significantly increased the ALP activity of Saos-2 cells cultured on chitosan membranes. This novel composite membranes with tunable properties could be considered as a potential candidate for guided bone regeneration applications.

AB - A simple solvent-free protocol for the preparation of flunixin, a potent non narcotic, non-steroidal anti-inflammatory drugs is reported using boric acid as catalyst. Its salt, flunixin meglumine are then prepared under reflux in EtOH. This sustainable method are then extended for the synthesis of a series of 2 (arylamino) nicotinic acid derivatives. The present protocol combines non hazardous neat conditions with associated benefits like excellent yield, straightforward workup, and use of readily available and safe catalyst in the absence of any solvent, which are important factors in the pharmaceutical industry. The pathway for catalytic activation of 2-chloronicotic acid with boric acid was also investigated using Gaussian 03 program package. PMID- 29196902 TI - Current Demographics and Roles of Florida Community Health Workers: Implications for Future Recruitment and Training. AB - The high prevalence of health disparity diseases (e.g., obesity, Type 2 diabetes) among underserved populations in the United States suggests the need for increased resources to prevent these diseases and to improve health care access and quality in underserved communities. Community health workers are valuable resources and facilitators of health care access and quality treatment. The purpose of the present study is to provide descriptive information about community health workers in Florida and to provide recommendations for improved training and expansion of community health workers' roles in research and intervention. The study participants were 396 adults (85.1% Female, 75.5% Community health workers) who completed the 2015 Florida Community Health Workers Census. Participants were recruited by the Health Council of South Florida through emails and phone calls to members of the Florida Community Health Worker Coalition and various organizations. It was found that several groups disproportionately affected by health disparities were underrepresented among the community health workers who participated in the census and among the communities served by these community health workers. Actions are needed to improve and increase the recruitment and training of community health workers in Florida. PMID- 29196903 TI - Concurrent Use of Prescription Drugs and Herbal Medicinal Products in Older Adults: A Systematic Review. AB - BACKGROUND: The use of herbal medicinal products (HMPs) is common among older adults; however, little is known about concurrent use with prescription drugs, as well as potential interactions associated with such combinations. OBJECTIVE: The aim of this systematic review was to identify and evaluate the literature on concurrent prescription and HMP use among older adults to assess prevalence, patterns, potential interactions and factors associated with this use. METHODS: Systematic searches were conducted in the MEDLINE, PsycINFO, EMBASE, CINAHL, AMED, Web of Science and Cochrane databases from inception to May 2017 for studies reporting concurrent use of prescription medicines with HMPs in adults >= 65 years of age. Quality was assessed using the Joanna Briggs Institute checklists. And the Evidence for Policy and Practice Information and Co ordinating Centre (EPPI-Centre) three-stage approach to mixed method research was used to synthesise data. RESULTS: Twenty-two studies were included. A definition of HMPs or what was considered an HMP was frequently missing. Prevalence of concurrent use by older adults varied widely between 5.3 and 88.3%. Prescription medicines most combined with HMPs were antihypertensive drugs, beta-blockers, diuretics, antihyperlipidemic agents, anticoagulants, analgesics, antihistamines, antidiabetics, antidepressants and statins. The HMPs most frequently used were Ginkgo biloba, garlic, ginseng, St John's wort, Echinacea, saw palmetto, evening primrose oil and ginger. Potential risks of bleeding due to the use of Ginkgo biloba, garlic or ginseng with aspirin or warfarin was the most reported herb drug interaction. Some data suggest being female, and having a lower household income and less than a high-school education were associated with concurrent use. CONCLUSION: The prevalence of concurrent prescription drugs and HMP use among older adults is substantial and potential interactions have been reported. Knowledge of the extent and manner in which older adults combine prescription drugs will aid healthcare professionals in appropriately identifying and managing patients at risk.

AB - Management of patients undergoing treatment for cancer requires a multidisciplinary team including general dentistry providers; however, the relative knowledge and training of general dentists in the management of this patient population are relatively unknown. The purpose of this study was to assess the oncology curricula of postgraduate general dentistry training programs, from the perspective of the program directors, to better understand the opportunities for and/or barriers to dental care for cancer patients. A cross sectional survey was sent to the 275 Commission on Dental Accreditation accredited programs; 82 program directors responded (response rate, 30%). More than 50% of respondents indicated "none" or "little" curricular emphasis on cancer biology, bone marrow transplantation, immunotherapy, or prosthetics for use during head and/or neck surgery. Conversely, more than 50% of respondents indicated "moderate" or "substantial" emphasis on acute oral effects of cancer related therapy, long-term oral effects of cancer-related therapy, antiresorptive medication pharmacology, radiotherapy techniques and biological effects, and osteonecrosis of the jaw. Residents had the most experience with radiotherapy patients and the least with bone marrow or transplantation patients. Overall, general dentistry program directors were enthusiastic to participate in the multidisciplinary team but reported challenges to including oncology curricula in residency training programs. Training for general dentistry providers in formalized postgraduate residency programs may be variable or limited-as a result, communication regarding patient management is critical. Opportunities exist to enhance the general dentistry curricula and, thereby, improve access to dental care for patients receiving treatment for cancer. PMID- 29196906 TI - Perceptions and Attitudes of Cancer Patients and Caregivers Towards Enrollment in Clinical Trials in Lebanon. AB - The rates of participation in oncology clinical trials (CTs) are relatively lower in the Middle East compared to other areas in the world. Many social and cultural factors underlie the patients' reluctance to participate. To probe the knowledge, attitudes, and perceptions of patients with cancer and their caregivers regarding participation in CTs at our tertiary referral center in Lebanon, we interviewed 210 patients and caregivers visiting the outpatient clinics in the Naef Basile Cancer Institute at the American University of Beirut. A questionnaire was derived from literature and administered in Arabic. The study was approved by the Institutional Review Board (IRB). Two hundred individuals agreed to answer the questionnaire. The majority of participants (90.5%) were Lebanese with the remaining being non-Lebanese Arabs. Eighty-nine participants (45%) were aware of the concepts of CTs. Eighty-two respondents (41%) would participate in phase I CTs. Twenty-nine individuals (14.5%) agree to be enrolled in CTs with the approval of their family members only. One hundred twenty-nine subjects (64.5%) stated that they would refuse enrollment in a CT where they might receive placebo. Eighty-eight (44%) of participants considered that medical records could be reviewed for research without consent while 54% agreed that samples collected during clinical workup could be used for research without the consent of the patient. There are several social and demographic correlates for participation in CTs. Raising awareness and overcoming barriers of misconception are keys to promote participation in CTs in Lebanon.

AB - KEY MESSAGE: We have successfully produced single-cell colonies of C. merolae mutants, lacking the PsbQ' subunit in its PSII complex by application of DTA aided mutant selection. We have investigated the physiological changes in PSII function and structure and proposed a tentative explanation of the function of PsbQ' subunit in the PSII complex. We have improved the selectivity of the Cyanidioschyzon merolae nuclear transformation method by the introduction of diphtheria toxin genes into the transformation vector as an auxiliary selectable marker. The revised method allowed us to obtained single-cell colonies of C. merolae, lacking the gene of the PsbQ' extrinsic protein. The efficiency of gene replacement was extraordinarily high, allowing for a complete deletion of the gene of interest, without undesirable illegitimate integration events. We have confirmed the absence of PsbQ' protein at genetic and protein level. We have characterized the physiology of mutant cells and isolated PSII protein complex and concluded that PsbQ' is involved in nuclear regulation of PSII activity, by influencing several parameters of PSII function. Among these: oxygen evolving activity, partial dissociation of PsbV, regulation of dimerization, downsizing of phycobilisomes rods and regulation of zeaxanthin abundance. The adaptation of cellular physiology appeared to favorite upregulation of PSII and concurrent downregulation of PSI, resulting in an imbalance of energy distribution, decrease of photosynthesis and inhibition of cell proliferation.

AB - Fluorescence investigations on interactions between 7,8-benzo-4-azidomethyl coumarin (7BAMC) and quenchers ortho-phenylenediamine (OPD) and para phenylenediamines (PPD) in binary solvent mixtures (THF + water) have been reported. UV-absorption study indicated a weak hydrophobic interaction between 7BAMC and the para isomer. NMR spectral studies indicated the presence of an interaction between 7BAMC and PPD. Magnitudes of the parameters associated with FRET, showed the presence of interactions between 7BAMC and PPD quencher is more predominant than OPD. Fluorescence quenching studies reveal the role of static and dynamic quenching pathways, depending upon Stern-Volmer constant, dielectric constant and dominant non-radiative processes. Binding equilibria analysis indicates a strong interaction between 7BAMC and PPD than OPD and formation of H bonding. Based on the magnitudes of free energy, enthalpy change and entropy, bimolecular interaction process may be considered as spontaneous and hydrophobic. PMID- 29196908 TI - Do chimpanzees anticipate an object's weight? A field experiment on the kinematics of hammer-lifting movements in the nut-cracking Tai chimpanzees. AB - When humans are about to manipulate an object, our brains use visual cues to recall an internal representation to predict its weight and scale the lifting force accordingly. Such a long-term force profile, formed through repeated experiences with similar objects, has been proposed to improve manipulative performance. Skillful object manipulation is crucial for many animals, particularly those that rely on tools for foraging. However, despite enduring interest in tool use in non-human animals, there has been very little investigation of their ability to form an expectation about an object's weight. In this study, we tested whether wild chimpanzees use long-term force profiles to anticipate the weight of a nut-cracking hammer from its size. To this end, we conducted a field experiment presenting chimpanzees with natural wooden hammers and artificially hollowed, lighter hammers of the same size and external appearance. We used calibrated videos from camera traps to extract kinematic parameters of lifting movements. We found that, when lacking previous experience, chimpanzees lifted hollowed hammers with a higher acceleration than natural hammers (overshoot effect). After using a hammer to crack open one nut, chimpanzees tuned down the lifting acceleration for the hollowed hammers, but continued lifting natural hammers with the same acceleration. Our results show that chimpanzees anticipate the weight of an object using long-term force profiles and suggest that, similarly to humans, they use internal representations of weight to plan their lifting movements. PMID- 29196909 TI - Rhesus monkeys (Macaca mulatta) remember agency information from past events and integrate this knowledge with spatial and temporal features in working memory. AB - The purpose of the present study was to examine whether rhesus monkeys remember information about their own agency-along with spatial, temporal and contextual properties-from a previously experienced event. In Experiment 1, rhesus monkeys (n = 4) used symbols to reliably indicate whether they had performed or observed an event on a computer screen. In Experiment 2, naive and experienced monkeys (n = 8) reported agency information when stringent controls for perceptual and proprioceptive cues were included. In Experiment 3, five of the monkeys completed a task in which they reported agency information along with spatial and temporal features of events. Two monkeys performed this agency discrimination when they could not anticipate which memory test they would receive. There was also evidence that these features were integrated in memory. Implications of this research are discussed in relation to working memory, episodic memory and self awareness in nonhuman animals.

PMID- 29196910 TI - Radiopharmaceutical tracers for cardiac imaging. AB - Cardiovascular disease (CVD) is the leading cause of death and disease burden worldwide. Nuclear myocardial perfusion imaging with either single-photon emission computed tomography or positron emission tomography has been used extensively to perform diagnosis, monitor therapies, and predict cardiovascular events. Several radiopharmaceutical tracers have recently been developed to evaluate CVD by targeting myocardial perfusion, metabolism, innervation, and inflammation. This article reviews old and newer used in nuclear cardiac imaging. PMID- 29196913 TI - UBAP2L silencing inhibits cell proliferation and G2/M phase transition in breast cancer. AB - BACKGROUND: Ubiquitin-associated protein 2-like (UBAP2L) contains a ubiquitin associated domain near its N-terminus, which has been demonstrated to be overexpressed in multiple tumors, including hepatocellular carcinoma and colorectal carcinoma but its role has not been well studied in breast cancer. Thus, this study was designed to evaluate whether UBAP2L can serve as a potential molecular target for breast cancer therapy. METHODS: The expression of UBAP2L was determined in breast cancer tissues and cell lines by Western blotting and Oncomine database mining. Then the expression of UBAP2L was silenced using RNA interference and the effects of UBAP2L knockdown on breast cancer cell proliferation and cell cycle progression by MTT and colony formation assay, and Flow cytometry, respectively. RESULTS: We found the expression of UBAP2L was significantly up-regulated in breast cancer tissues and cell lines. Knockdown of UBAP2L suppressed cell proliferation, impaired colony formation ability and induced cell cycle arrest at G2/M phase. At molecular levels, knockdown of UBAP2L increased p21 expression, but decreased the expression of CDK1 and Cyclin B1 in breast cancer cells. CONCLUSION: Our findings suggest that UBAP2L plays an important role in breast cancer cell proliferation and might serve as a potential target for breast cancer treatment. PMID- 29196914 TI - Health care utilisation amongst older adults with sensory and cognitive impairments in Europe. AB - Worldwide, the high prevalence of multiple chronic conditions amongst older population has led to increased utilisation of health care and rising associated costs, becoming a major public health concern. Hearing, vision and cognitive disorders are common chronic conditions amongst older Europeans and recent studies have documented its high co-occurrence. While it has been shown separately that suffering either mental disorders or sensory (hearing and vision) impairments is associated with higher health care utilisation, the association between health care utilisation and the interaction of these conditions has received little attention in the literature. Therefore, using four waves of the Survey of Health, Ageing and Retirement in Europe (SHARE), this study applies the correlated random effects method to the negative binomial and finite mixture models to analyse the extent to which the interaction of cognitive and sensory impairments is associated with health care use. We found that individuals with cognitive impairment tend to have more hospitalisations. The finite mixture approach indicates a positive association between sensory impairment and the number of hospitalisations amongst low users of health care. Additionally, our findings suggest a positive association between suffering both impairments at the same time and the number of doctor and GP visits.

PMID- 29196916 TI - Bullying Victimization Heightens Cortisol Response to Psychosocial Stress in Chinese Children. AB - Childhood adverse experiences have been consistently documented to engender persistent changes in the hypothalamic-pituitary-adrenal (HPA) axis reactivity to chronic stress. However, there has been very little research examining whether this effect can be elicited among children when using a standardized laboratory stress test, or whether such effects are found in non-Western youth. In the current study, 80 10-year-old Chinese children (45% girls, 4-5th grades) were selected from 970 students based on the experience of being bullied, resulting in a sample of 59 victims (physical, verbal, and relational/social), and a group of 21 nonbullied children with distributions of age and gender that were comparable. We examined the association between bullying victimization and cortisol reactivity to the Trier Social Stress Test (TSST) at six time points using repeated-measures analyses of variance. The results showed that the TSST was a valid protocol among Chinese children for testing the functioning of HPA axis, based on two indicators: cortisol increase in response to stressor, and cortisol decrease after stressor removal. Based on the TSST, both cortisol reactivity and total cortisol concentration over the course of TSST were higher in bullied children relative to nonbullied children. Moreover, there were no differences in cortisol levels between victimization sub-types. Our study extended prior findings, by showing that cortisol dysregulation in response to stress may be related to bullying victimization. PMID- 29196917 TI - Development of a linear dual column HPLC-MS/MS method and clinical genetic evaluation for tramadol and its phase I and II metabolites in oral fluid. AB - Tramadol is a centrally acting synthetic opioid analgesic and has received special attention due to its abuse potential and unexpected responses induced by CYP2D6 polymorphism. Oral fluid is an advantageous biofluid for drug analysis due to non-invasive sampling and high correlation of drug concentrations with plasma. However, few studies have been performed on distribution of tramadol and its metabolites in oral fluid. In the present study, a linear dual column HPLC-MS/MS method was developed and fully validated for the simultaneous determination of tramadol and its phase I [O-desmethyltramadol (ODMT), N-desmethyltramadol (NDMT) and N,O-didesmethyltramadol (NODMT)] and II metabolites in oral fluid. Furthermore, the distribution of tramadol and its metabolites, in relation to CYP2D6 genetic variations, in oral fluid was investigated following a clinical study including 23 subjects with CYP2D6*wt/*wt, CYP2D6*10/*10 or CYP2D6*5/*5. The validation results of selectivity, matrix effect, linearity, precision and accuracy were satisfactory. Pharmacokinetic parameters, such as Css,max and AUC0 tau of tramadol, NDMT and NODMT, in the CYP2D6*10/*10 group were significantly higher than those in the CYP2D6*wt/*wt group. Moreover, the ratios of ODMT/tramadol, NDMT/tramadol and NODMT/NDMT correlated well with the CYP2D6 genotypes. We demonstrated that oral fluid is a promising biofluid for pharmacokinetic evaluation in relation to genetic variations. PMID- 29196918 TI - Nafamostat mesilate negatively regulates the metastasis of triple-negative breast cancer cells. AB - Triple-negative breast cancer (TNBC) lacking of oestrogen receptor, progesterone receptor, and epidermal growth factor receptor type 2 is a highly malignant disease which results in a poor prognosis and rare treatment options. Despite the use of conventional chemotherapy for TNBC tumours, resistance and short duration responses limit the treatment efficacy. Therefore, a need exists to develop a new chemotherapy for TNBC. The aim of this study was to examine the anti-cancer effects of nafamostat mesilate (NM), a previously known serine protease inhibitor and highly safe drug on breast cancer cells. Here, we showed that NM significantly inhibits proliferation, migration, and invasion in MDA-MB231 cells, induces G2/M phase cell-cycle arrest, and inhibits the expression of cyclin dependent kinase 1 (CDK1). Exposure of MDA-MB231 cells to NM also resulted in decreased transcription factor activities accompanied by the regulated phosphorylation of signalling molecules and a decrease in metalloproteinases, the principal modulators of the extracellular environment during cancer progression. Especially, inhibition of TGFbeta-stimulated Smad2 phosphorylation and subsequent metastasis-related gene expression, and downregulation of ERK activity may be pivotal mechanisms underlying inhibitory effects of NM on NM inhibits lung metastasis of breast cancer cells and growth of colonized tumours in mice. Taken together, our data revealed that NM inhibits cell growth and metastasis of TNBC cells and indicated that NM is a multi-targeted drug that could be an adjunct therapy for TNBC treatment.

AB - The combined effects of a commercial probiotic, BetaPlus(r), and a prebiotic, isomaltooligosaccharides (IMOS) on the growth, survival rate, intestinal microbiota, and hemato-immunological parameters were evaluated in Caspian brown trout (Salmo trutta caspius Kessler, 1877). Caspian brown trout fingerlings (~ 9 g) were fed a control diet (basal diet) or a synbiotic diet (the basal diet + 2 g kg-1 IMOS + 1 g kg-1 BetaPlus(r)) for 7 weeks. At the end of this trial, fish fed the synbiotic diet showed significant improvements in body weight increase, feed conversion ratio, and survival rate compared with fish fed the control diet (P < 0.05). In addition, fish fed the synbiotic diet had the highest levels of white blood cells, monocytes, and neutrophils (P < 0.05), while the red blood cells, hemoglobin, hematrocrit, mean corpuscular volume, and lymphocytes were significantly higher in the control group (P < 0.05). The serum triglycerides, cholesterol, total protein, albumin, albumin/globulin ratio, and immunoglobulin M levels, as well as alanine aminotransferase and lactate dehydrogenase activities were higher in the synbiotic group than in the control group (P < 0.05). In addition, fish fed the synbiotic diet showed significantly higher gut total viable aerobic bacterial counts and lactic acid bacteria (P < 0.05). The results demonstrated that BetaPlus(r) in combination with IMOS enhanced the growth, survival rate, intestinal microbiota, and some haemato-immunological parameters in Caspian brown trout fingerlings. PMID- 29196920 TI - Probiotic Bacillus coagulans GBI-30, 6086 Improves Protein Absorption and Utilization. AB - Probiotics offer numerous health benefits, including digestive and immune health. Improved digestive health is linked to a more efficient absorption of important nutrients from our diet. This review focused on the rationale of using the probiotic Bacillus coagulans GBI-30, 6086 to aid protein absorption and utilization. B. coagulans GBI-30, 6086 can withstand the acidic environment of the stomach to reach the intestine where it germinates. Once active in the small intestine after germination, it has been shown to aid the digestion of carbohydrates and proteins. Co-administration of B. coagulans GBI-30, 6086 with protein has been shown to increase protein absorption and to maximize the health benefits associated with protein supplementation. PMID- 29196921 TI - Viability and Stress Response of Putative Probiotic Lactobacillus plantarum Strains in Honey Environment. AB - Due to problem of preservation of dairy products which serve as a matrix for probiotics, it is challenging to use these probiotics as food supplements in many developing countries. To determine the suitability of the Lactobacillus strains for exploitation as probiotics in honey, we investigated the effect of their storage on the viability, functionality, and the mechanism associated with their protective effect. Three isolates obtained from our laboratory collection were identified through amplification of the 16S rRNA gene. The viability of the strains in honey at different storage conditions was studied. Three genes (hdc, gtf, and clpL) responsible for the resistance of bacteria in acidic environments were screened. SDS-PAGE analysis of total protein was performed to observe protein profile changes of the strains after exposure to honey. All the three isolates, namely, GGU, GLA51, and GLP56, were identified as Lactobacillus plantarum strains. After 28 days of storage in honey at 4 degrees C, viable cell concentrations of the three strains were higher than 2.04 * 106 CFU/ml. During the same period at room temperature, only the Lactobacillus plantarum GLP56 strain remained viable with a cell concentration of 1.86 * 104 CFU/ml. The clpL gene coding for ATPase was detected in all the three strains. The protein of molecular weight ~ 50 kDa was absent in the protein profile of Lactobacillus plantarum GGU after 60 days of storage in honey at 4 degrees C. The Lactobacillus plantarum GLP56, Lactobacillus plantarum GLA51, and Lactobacillus plantarum GGU strains exposed to honey can withstand acidic environmental stress but their viability declines over time. PMID- 29196922 TI - Nosocomial Candiduria in the Elderly: Microbiological Diagnosis. AB - Candiduria is associated with high morbidity, mortality, and long hospitalization, involving high costs for the healthcare system. The use of increasingly aggressive treatments has prolonged the lives of patients susceptible to candiduria, namely the immunosuppressed, the premature, and the elderly. Our objective was to evaluate the incidence of nosocomial candiduria and the implicated species in hospitalized patients aged over 80 years old from three Spanish centers during 2012 and 2013. Urine samples received from these patients were cultured and analyzed by flow cytometry in search of leukocyturia, hematuria, proteinuria, and microbial nitrate reductase activity. The isolated yeast species were identified microscopically, by germ tube formation in serum, colony morphology after subculture onto CHROMagar Candida (Becton-Dickinson, UK), assimilation of carbon compounds ID32C (bioMerieux, France), matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDITOF) (Bruker Daltonics, Germany) and, in case of inconsistency, by sequencing of the ITS regions of ribosomal DNA (ITS1-5, 8S-ITS2). Susceptibility tests were also performed. The incidence of candiduria in the elderly population was 10.3%. A total of 155 strains of yeasts were isolated. The predominant species was Candida albicans, followed by Candida glabrata and then Candida tropicalis. Several infrequent species were found; among them, the first isolate of candiduria producing Candida pulcherrima described in the literature. Our finding should raise concerns about the elderly population, which is probably the most important risk group for candiduria in the present moment, and the emergence of unusual yeast species producing candiduria, which are resistant against the commonly used antifungal agents. PMID- 29196923 TI - Mixed Infection of Respiratory Tract in a Dog Caused by Rhodotorula mucilaginosa and Trichosporon jirovecii: A Case Report. AB - This report describes the isolation of two environmental fungi: Rhodotorula mucilaginosa and Trichosporon jirovecii accompanied by Pseudomonas aeruginosa and Escherichia coli from a dog with bronchotracheitis. All microorganisms were isolated routinely from a mucopurulent discharge, obtained during bronchoscopy from laryngotracheal area. The initial identification of yeasts was confirmed by API Candida and by molecular analysis of internal transcribed spacer region. Administered antimicrobial treatment with Marbofloxacin and Canizol has brought the improvement in the dogs' health status. The final results of control mycological culture were negative. Most probably underlying hypothyroidism and the use of steroids were the factors predisposing this patient to opportunistic infection of mixed aetiology. As far as we are concerned, this is the first case of dogs' respiratory tract infection caused by R. mucilaginosa and T. jirovecii. PMID- 29196924 TI - Cutaneotrichosporon (Trichosporon) debeurmannianum: A Rare Yeast Isolated from Blood and Urine Samples. AB - Cutaneotrichosporon (Trichosporon) debeurmannianum is a rarely isolated yeast from clinical samples. Nine isolates of this yeast were identified from clinical samples within a period of 3 years from June 2012 to May 2015. These isolates were from blood and urine samples sent to a clinical mycology laboratory of a tertiary care hospital in Assam, North East India. Clinically, the patients were diagnosed as septicemia and urinary tract infection. The age of the patients ranged from 2 to 50 years. Identification was made by sequencing the ITS region of ribosomal RNA gene. Antifungal susceptibility test by disk diffusion method (CLSI, M44-A) showed all the isolates to be sensitive to fluconazole and voriconazole. Vitek 2 compact commercial yeast identification system misidentified this yeast as Cryptococcus laurentii and low discrimination Cryptococcus laurentii/Trichosporon mucoides. This species was originally named as Trichosporon debeurmannianum. In 2015, this yeast has been included into new genera Cutaneotrichosporon based on an integrated phylogenetic classification of the Tremellomycetes. To the best of our knowledge, this is the first report of identification of this species from blood and urine samples of clinically suspected cases. We are reporting these isolates because of their rarity in clinical samples. The pathogenic potential and epidemiological relevance of this yeast remains to be seen. PMID- 29196925 TI - Pre-operative language ability in patients with presumed low-grade glioma. AB - In patients with low-grade glioma (LGG), language deficits are usually only found and investigated after surgery. Deficits may be present before surgery but to date, studies have yielded varying results regarding the extent of this problem and in what language domains deficits may occur. This study therefore aims to explore the language ability of patients who have recently received a presumptive diagnosis of low-grade glioma, and also to see whether they reported any changes in their language ability before receiving treatment. Twenty-three patients were tested using a comprehensive test battery that consisted of standard aphasia tests and tests of lexical retrieval and high-level language functions. The patients were also asked whether they had noticed any change in their use of language or ability to communicate. The test scores were compared to a matched reference group and to clinical norms. The presumed LGG group performed significantly worse than the reference group on two tests of lexical retrieval. Since five patients after surgery were discovered to have a high-grade glioma, a separate analysis excluding them were performed. These analyses revealed comparable results; however one test of word fluency was no longer significant. Individually, the majority exhibited normal or nearly normal language ability and only a few reported subjective changes in language or ability to communicate. This study shows that patients who have been diagnosed with LGG generally show mild or no language deficits on either objective or subjective assessment. PMID- 29196926 TI - Glioblastoma and acute myeloid leukemia: malignancies with striking similarities. AB - Acute myeloid leukemia (AML) and glioblastoma (GB) are two malignancies associated with high incidence of treatment refractoriness and generally, uniformly poor survival outcomes. While the former is a hematologic (i.e. a "liquid") malignancy and the latter a solid tumor, the two diseases share both clinical and biochemical characteristics. Both diseases exist predominantly in primary (de novo) forms, with only a small subset of each progressing from precursor disease states like the myelodysplastic syndromes or diffuse glioma. More importantly, the primary and secondary forms of each disease are characterized by common sets of mutations and gene expression abnormalities. The primary versions of AML and GB are characterized by aberrant RAS pathway, matrix metalloproteinase 9, and Bcl-2 expression, and their secondary counterparts share abnormalities in TP53, isocitrate dehydrogenase, ATRX, inhibitor of apoptosis proteins, and survivin that both influence the course of the diseases themselves and their progression from precursor disease. An understanding of these shared features is important, as it can be used to guide both the research about and treatment of each. PMID- 29196927 TI - Characteristics of cerebellar glioblastomas in adults. AB - Adult cerebellar glioblastomas (cGBM) are rare and their characteristics remain to be fully described. We analyzed the characteristics of 17 adult patients with cGBM and compared them to a series of 103 patients presenting a supra-tentorial glioblastoma (stGBM). The mean age at GBMc diagnosis was 53.4 years (range 28 77). A history of neurofibromatosis type I was noted in 3 patients. cGBM were hemispheric in 10 patients (58.8%), only vermian in 4 patients (23.5%), and both vermian and hemispheric in 3 patients (17.7%). A H3 K27M mutation was identified in 3/14 patients, a TERT promoter mutation in 3/14 patients and a methylated MGMT promoter in 3/14 patients. None of the patients (0/14) harbored an EGFR amplification, an IDH or a BRAF mutation. Association with neurofibromatosis type I and H3K27M mutations were mutually exclusive. Compared with stGBM, cGBM occurred in younger patients (53.4 vs. 63.2, p = 0.02), were more frequently associated with neurofibromatosis type I (18 vs. 1%, p = 0.009) and with a H3 K27M mutation (21 vs. 3%, p = 0.02). They also tended to have a more frequent multifocal presentation at diagnosis (21 vs. 4.3%, p = 0.06), more frequently resulted in leptomeningeal or intra-axial metastasis (44.5 vs. 5%, p = 0.002) and were associated with a shorter median overall survival (5.9 vs. 14.2 months, p = 0.004). The present study suggests that adult cGBM differ from their supra tentorial counterpart and constitute a heterogeneous group of IDH wild-type gliomas with at least two subgroups, one associated with H3K27M mutations and the other with neurofibromatosis type I. PMID- 29196928 TI - The effect of L-thyroxine substitution on oxidative stress in early-stage diabetic nephropathy patients with subclinical hypothyroidism: a randomized double-blind and placebo-controlled study. AB - PURPOSE: To study oxidative stress status of early type 2 diabetic nephropathy (DN) patients with subclinical hypothyroidism (SCH) and to assess effect of L thyroxine therapy on the oxidative stress in these patients. METHODS: It is a randomized double-blind and placebo-controlled trial. A total of 48 patients with early type 2 DN were included as Euthyroid group, and 92 early type 2 DN with SCH were selected and randomly assigned to L-thyroxine treatment group (LT4 group) and placebo group (SCH group). Changes in urinary albumin excretion rate (UAER), serum malondialdehyde (MDA), superoxide dismutase (SOD) activity, urine 8 hydroxyl deoxyguanosine (8-OHdG), serum creatinine, estimated glomerular filtration rate, and lipid profile before and after 24 weeks of follow-up were examined and compared. RESULTS: The levels of UAER, MDA, 8-OHdG were higher, while the SOD activity was lower in DN patients with SCH than in DN patients (p < 0.05 for all). In the LT4 group, the levels of UAER, MDA, 8-OHdG decreased significantly (p < 0.05) to levels no longer different from the Euthyroid group. The SOD activity increased significantly. But in SCH group, the levels of mAlb, MDA, 8-OHdG were greater after 24 weeks of follow-up and greater than patients in the Euthyroid group. SOD activity decreased significantly after 24 weeks in the SCH group (p < 0.05). CONCLUSION: Oxidative stress is greater in the DN patients with SCH, and SCH may exacerbate kidney injury in early DN patients. The LT4 treatment may decrease the oxidative stress and attenuate renal injury in DN patient with SCH. PMID- 29196929 TI - Factors associated with calcium requirements after parathyroidectomy in chronic kidney disease patients. AB - BACKGROUND: Renal hyperparathyroidism is a common complication of chronic kidney disease (CKD). Parathyroidectomy (PTX) for these patients continues to be a valuable option in the era of calcimimetics. Postoperative hypocalcemia is common after surgery. The aim of this study was to identify clinical factors to define postoperative calcium requirements. METHODS: From February 2013 to May 2017, 68 patients with chronic kidney disease 5 (CKD5) who underwent PTX were reviewed. We collected clinical and laboratory data preoperatively and calculated the total calcium requirement in a week after surgery. Univariate and multiple analyses were performed to study whether these clinical and laboratory factors were associated with calcium requirement. RESULTS: Univariate analysis showed that preoperative alkaline phosphatase (ALP), calcium (Ca), parathyroid hormone and hemoglobin were independently associated with calcium requirement. Multivariate model showed that the preoperative ALP was the only independent factor that could predict the requirement of calcium. CONCLUSIONS: In the context of a high dCa (1.75 mmol/l) and a stable dose of calcitriol, preoperative ALP levels were significantly associated with calcium requirement in patients with CKD5 undergoing PTX. PMID- 29196930 TI - Association of ALOX12 gene polymorphism with all-cause and cardiovascular mortality in diabetic nephropathy. AB - PURPOSE: Cardiovascular (CV) events are the first cause of death in patients with chronic renal disease (CKD) and in patients with type 2 diabetes mellitus (DM2). The combination of CKD and DM2 elevates the risk of both cardiovascular disease (CVD) and death in this high-risk population. Besides traditional risk factors, such as dyslipidemia, smoking, obesity, and carotid atherosclerosis, novel factors are under investigation such as genetic polymorphisms. Lipoxygenases (LOXs) and their genes are of critical importance in oxidative stress, inflammation, and atherosclerosis. The aim of the study is to clarify a potential ALOX12 role in CVD presence and progress of diabetic patients in different stages of nephropathy. METHODS: We studied 145 patients with a documented history of DM2 for at least 10 years and diabetic nephropathy (DN), mean age 68 +/- 9 years, body mass index 31 +/- 5 kg/m2, and different stages of renal disease, depending on glomerular filtration rate. The sample population consisted of two groups: 108 DM2 patients with DN in all five stages of CKD and 37 DM2 patients as controls. Anthropometric and clinical characteristics, interview for history of previous CV event, and assessment of carotid intima-media thickness (cIMT) were recorded at baseline. All patients were genotyped for ALOX12 polymorphisms with focus on rs14309. Genotypes (AA, AG, and GG) were evaluated for any possible role in CVD, and grouping was performed on A genotype, which is the dominant model. All participants were followed over a period of 7 years, and the end points studied were all-cause mortality, CV mortality, and CV events. CV events were defined as myocardial infarction (MI), stroke, or peripheral artery disease. RESULTS: The GG genotype has been significantly associated with cIMT levels above 0.86 mm and with history of MI. Regarding the presence of an atherosclerotic plaque in either carotid artery, no significant association was found when the genotypes were assessed on their own. After grouping, though, GG genotype revealed a significant association between carotid plaque formation and atheromatosis. Kaplan-Meier analysis revealed that ALOX12 gene GG genotype predicted all-cause mortality, CV mortality, and CV events. Similarly, when AA and AG genotypes were grouped, Kaplan-Meier analysis showed that patients with GG genotype presented an even more significant higher all-cause mortality, CV mortality, and CV events compared with AA and AG genotypes combined. After adjustment for several traditional risk factors, multivariate Cox proportional hazard analysis showed that patients with the GG genotype had a significant higher risk of all-cause mortality, a threefold increase in CV mortality, and a twofold increased risk for CV events compared to patients with the AA or the AG genotype. CONCLUSION: ALOX12 rs14309 GG genotype expression was found to be significantly associated with MI, higher cIMT, increased CV events, CV, and overall mortality. This phenomenon could be partially explained by the increased platelet proaggregatory activity of AA products and the control they exert in thrombotic occurrence and plaque formation. PMID- 29196931 TI - Metabolic Syndrome and Bone: Pharmacologically Induced Diabetes has Deleterious Effect on Bone in Growing Obese Rats. AB - Metabolic syndrome and osteoporosis share similar risk factors. Also, patients with diabetes have a higher risk of osteoporosis and fracture. Liver manifestations, such as non-alcoholic steatohepatitis (NASH), of metabolic syndrome are further aggravated in diabetics and often lead to liver failure. Our objective was to create a rat model of human metabolic syndrome and determine the long-term impact of early-onset T1D on bone structure and strength in obese growing rats. Male rats were given either standard chow and RO water (Controls) or a high-fat, high-cholesterol diet and sugar water containing 55% fructose and 45% glucose (HFD). A third group of rats received the HFD diet and a single dose of streptozotocin to induce type 1 diabetes (HFD/Sz). Body weight and glucose tolerance tests were conducted several times during the course of the study. Serum chemistry, liver enzymes, and biomarkers of bone metabolism were evaluated at 10 and 28 weeks. Shear wave elastography and histology were used to assess liver fibrosis. Cancellous bone structure and cortical bone geometry were evaluated by mCT and strength by the 3-point bending method. Body mass and fat accumulation was significantly higher in HFD and HFD/Sz rats compared to Controls. Rats in both the HFD and HFD/Sz groups developed NASH, although the change was more severe in diabetic rats. Although both groups of obese rats had larger bones, their cancellous structure and cortical thickness were reduced, resulting in diminished strength that was further aggravated by diabetes. The HFD and HFD/Sz rats recapitulate MeSy in humans with liver pathology consistent with NASH. Our data provide strong indication that obesity accompanied by type 1 diabetes significantly aggravates comorbidities of MeSy, including the development of osteopenia and weaker bones. The juvenile rat skeleton seems to be more vulnerable to damage imposed by obesity and diabetes and may offer a model to inform the underlying pathology associated with the unusually high fracture rates in obese adults with diabetes.

AB - Low solubility of sterols in aqueous media limits efficient steroid production mediated by biocatalytic microorganisms such as Mycobacterium. Sterol emulsion technologies have been developed with low success rates, largely due to the complexity of generating stable and bioavailable particles. In this study, several aqueous dispersions of sterols in-water of different particle sizes were bioconverted to 4-androstene-3,17-dione (AD) in a solvent-free environment, using a classic microorganism Mycobacterium sp. B3805 as a model system. According to our results, the high concentration (20 g/L) phytosterol dispersions with the smallest particle size tested (370 nm) achieved up to 54% (7.4 g/L) AD production yield in 11 days. Moreover, the use of 0.1 biomass/sterols ratio in a complex bioconversion media containing yeast extract, and a 1:1 glucose/microdispersion ratio in the presence of the surfactant DK-Ester P-160 (HLB16), allowed homogenization and increased microdispersion stability, thus achieving the best results using emulsion technologies to date. PMID- 29196933 TI - Osmolyte Type and the Osmolarity Level Affect Chondrogenesis of Mesenchymal Stem Cells. AB - The inductive effects of increased osmolarity on chondrogenesis are well approved. However, the effects of the osmolyte agent invoked to induce hyperosmolarity are largely neglected. Herein, we scrutinized how hyperosmotic conditions acquired by addition of different osmolytes would impact chondrogenesis. We briefly assessed whether such conditions would differentially affect hypertrophy and angiogenesis during MSC chondrogenesis. Chondrogenic and hypertrophic marker expression along with VEGF secretion during adipose-derived (AD)-MSC chondrogenesis under three osmolarity levels (350, 450, and 550 mOsm) using three different osmolytes (NaCl, sorbitol, and PEG) were assessed. MTT assay, qRT-PCR, immunocytochemistry, Alcian Blue staining, ELISA, and ALP assays proved osmolyte-type dependent effects of hyperosmolarity on chondrogenesis, hypertrophy, and angiogenesis. At same osmolarity level, PEG had least cytotoxic/cytostatic effect and most prohibitive effects on angiogenesis. As expected, all hyperosmolar conditions led to enhanced chondrogenesis with slightly varying degrees. PEG and sorbitol had higher chondro-promotive and hypertrophy-suppressive effects compared to NaCl, while NaCl had exacerbated hypertrophy. We observed that TonEBP was involved in osmoadaptation of all treatments in varying degrees. Of importance, we highlighted differential effects of hyperosmolarity obtained by different osmolytes on the efficacy of chondrogenesis and more remarkably on the induction/suppression of cartilage pathologic markers. Our study underlies the need for a more vigilant exploitation of physicobiochemical inducers in order to maximize chondrogenesis while restraining unwanted hypertrophy and angiogenesis.

PMID- 29196935 TI - Serial femtosecond crystallography at the SACLA: breakthrough to dynamic structural biology. AB - X-ray crystallography visualizes the world at the atomic level. It has been used as the most powerful technique for observing the three-dimensional structures of biological macromolecules and has pioneered structural biology. To determine a crystal structure with high resolution, it was traditionally required to prepare large crystals (> 200 MUm). Later, synchrotron radiation facilities, such as SPring-8, that produce powerful X-rays were built. They enabled users to obtain good quality X-ray diffraction images even with smaller crystals (ca. 200-50 MUm). In recent years, one of the most important technological innovations in structural biology has been the development of X-ray free electron lasers (XFELs). The SPring-8 Angstrom Compact free electron LAser (SACLA) in Japan generates the XFEL beam by accelerating electrons to relativistic speeds and directing them through in-vacuum, short-period undulators. Since user operation started in 2012, we have been involved in the development of serial femtosecond crystallography (SFX) measurement systems using XFEL at the SACLA. The SACLA generates X-rays a billion times brighter than SPring-8. The extremely bright XFEL pulses enable data collection with microcrystals (ca. 50-1 MUm). Although many molecular analysis techniques exist, SFX is the only technique that can visualize radiation-damage-free structures of biological macromolecules at room temperature in atomic resolution and fast time resolution. Here, we review the achievements of the SACLA-SFX Project in the past 5 years. In particular, we focus on: (1) the measurement system for SFX; (2) experimental phasing by SFX; (3) enzyme chemistry based on damage-free room-temperature structures; and (4) molecular movie taken by time-resolved SFX.

PMID- 29196938 TI - The hemodynamic and pain impact of peripheral nerve block versus spinal anesthesia in diabetic patients undergoing diabetic foot surgery. AB - PURPOSE: Comparison of hemodynamic profiles and pain scores in diabetic patients undergoing diabetic foot surgery receiving peripheral nerve block (PNB) or spinal anesthesia [subarachnoid block (SAB)]. METHODS: This was a prospective, randomised controlled trial. We recruited diabetic patients aged > 18 years, American Society of Anesthesiologists class II-III, who were scheduled for unilateral diabetic foot surgery below the knee. All patients were assessed for autonomic dysfunction using the Survey of Autonomic Symptoms score. Participants were randomly assigned to receive either PNB or SAB for the surgery. Hemodynamic data, including usage of vasopressors, were recorded at 5-min intervals for up to 1 h after the induction of anesthesia. Pain scores were recorded postoperatively, and follow-up was done via telephone 6 months later. RESULTS: Compared to the PNB group, the SAB group had a larger number of patients with significant hypotension (14 vs. 1; p = 0.001) and more patients who required vasopressor boluses (6 vs. 0 patients). Compared to SAB group, the patients in the PNB group had a longer postoperative pain-free duration (9 vs. 4.54 h; p = 0.002) and lower pain scores 1 day after surgery (3.63 vs. 4.69; p = 0.01). CONCLUSION: Peripheral nerve block should be considered, whenever possible, as the first option of anesthesia for lower limb surgery in diabetic patients as it provides hemodynamic stability and superior postoperative pain control compared to SAB.

AB - A gastric subepithelial tumor is a common finding during upper gastric endoscopy. The differential diagnosis of such lesions is broad, and sometimes a rare disease can be diagnosed. A calcifying fibrous tumor (CFT) is a rare, benign mesenchymal tumor that usually affects children and young adults. To our knowledge, a CFT of the tubular gastrointestinal tract is very rare with fewer than 30 cases of gastric CFTs reported in the literature. PMID- 29196939 TI - Clinical and functional implication of the components of somatostatin system in gastroenteropancreatic neuroendocrine tumors. AB - PURPOSE: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) comprise a heterogeneous group of malignancies often presenting with metastasis at diagnosis and whose clinical outcome is difficult to predict. Somatostatin (SST) analogs (SSAs) provide a valuable pharmacological tool to palliate hormonal symptoms, and control progression in some NETs. However, many patients do not respond to SSAs or develop resistance, and there are many uncertainties regarding pathophysiology of SST and its receptors (sst1-sst5) in GEP-NETs. METHODS: The expression of SST system components in GEP-NETs was determined, compared with that of non-tumor adjacent and normal tissues and correlated with clinical and histological characteristics. Specifically, 58 patients with GEP-NETs and 14 normal samples were included. Cell viability in NET cell lines was determined in response to specific SSAs. RESULTS: Normal samples and non-tumor adjacent tissues presented a similar expression profile, with appreciable expression of sst2 and sst3, and a lower expression of the other receptors. In contrast, cortistatin, sst1, sst4, and sst5 were overexpressed in tumors, while sst3 and sst4 seemed overexpressed in less differentiated tumors. Some SST system components were related to vascular/nerve invasion and metastasis. In vitro, sst1 and sst3 agonists reduced viability in BON-1 cells, while they, similar to octreotide and pasireotide, increased viability in QGP-1 cells. CONCLUSIONS: These results provide novel information on SST system pathophysiology in GEP-NETs, including relevant associations with clinical-histological parameters, which might help to better understand the intrinsic heterogeneity of NETs and to identify novel biomarkers and/or targets with potential prognostic and/or therapeutic value for GEP-NETs patients. PMID- 29196940 TI - Evolution of intron-poor clades and expression patterns of the glycosyltransferase family 47. AB - MAIN CONCLUSION: A large-scale bioinformatics analysis revealed the origin and evolution of GT47 gene family, and identified two clades of intron-poor genes with putative functions in drought stress responses and seed development in maize. Glycosyltransferase family 47 (GT47) genes encode beta galactosyltransferases and beta-glucuronyltransferases that synthesize pectin, xyloglucans and xylan, which are important components of the plant cell wall. In this study, we performed a systematic and large-scale bioinformatics analysis of GT47 gene family using 352 GT47 proteins from 15 species ranging from cyanobacteria to seed plants. The analysis results showed that GT47 family may originate in cyanobacteria and expand along the evolutionary trajectory to moss. Further analysis of 47 GT47 genes in maize revealed that they can divide into five clades with diverse exon-intron structures. Among these five clades, two were mainly composed with intron-poor genes, which may originate in the moss. Gene duplication analysis revealed that the expansion of GT47 gene family in maize was significantly driven from tandem duplication events and segmental duplication events. Significantly, almost all duplicated genes are intron-poor genes. Expression analysis indicated that several intron-poor GT47 genes may be involved in the drought stress response and seed development in maize. This work provides insight into the origin and evolutionary process, expansion mechanisms and expression patterns of GT47 genes, thus facilitating their functional investigations in the future. PMID- 29196942 TI - Spinal movement and dural sac compression during airway management in a cadaveric model with atlanto-occipital instability. AB - PURPOSE: To analyze the compression of the dural sac and the cervical spinal movement during performing different airway interventions in case of atlanto occipital dislocation. METHODS: In six fresh cadavers, atlanto-occipital dislocation was performed by distracting the opened atlanto-occipital joint capsule and sectioning the tectorial membrane. Airway management was done using three airway devices (direct laryngoscopy, video laryngoscopy, and insertion of a laryngeal tube). The change of dural sac's width and intervertebral angulation in stable and unstable atlanto-occipital conditions were recorded by video fluoroscopy with myelography. Three-dimensional overall movement of cervical spine was measured in a wireless human motion track system. RESULTS: Compared with a mean dural sac compression of - 0.5 mm (- 0.7 to - 0.3 mm) in stable condition, direct laryngoscopy caused an increased dural sac compression of - 1.6 mm (- 1.9 to - 0.6 mm, p = 0.028) in the unstable atlanto-occipital condition. No increased compression on dural sac was found using video laryngoscopy or the laryngeal tube. Moreover, direct laryngoscopy caused greater overall extension and rotation of cervical spine than laryngeal tube insertion in both stable and unstable conditions. Among three procedures, the insertion of a laryngeal tube took the shortest time. CONCLUSION: In case of atlanto-occipital dislocation, intubation using direct laryngoscopy exacerbates dural sac compression and may cause damage to the spinal cord.

AB - PURPOSE: Wei et al. evaluated the global research in spine using scientometric methods based on a sample of 13,115 papers published in 5 spine journals from 2004 to 2013. This study builds on this pioneering study and provides up-to-date and thorough information on spine based on a sample of 166,962 papers for the stakeholders. METHOD: 'Articles' and 'reviews' published in 'English' in the journals indexed by the 'Web of Science' primary databases between 1980 and 2017 were retrieved through the use of an optimal keyword set for titles of both papers and ten spine journals. The information on document types and number of papers, authors, countries, funding bodies, institutions, publication years, journals, 'Web of Science' subject categories, and ten top citation classics were analyzed. RESULTS: A large sample of 166,962 papers were retrieved. The 'reviews' and 'proceedings papers' formed 5.8 and 2.8% of the sample, respectively. 'Fehlings', 'Vaccaro', 'Takahashi', 'Lenke', and 'Gokaslan' were the most prolific authors. Nearly 0.7% of the papers had group authors besides single authors. The US was the most prolific country publishing 37.3% of the sample whilst Europe contributed to more than 39.8% of the sample. Only, 26.6% of the papers disclosed research funding. Among 40,897 institutions, 'Harvard University' was the most-prolific institution whilst the US institutions dominated the top-institution list. The research output steadily rose from 1375 papers in 1980 to 9357 papers in 2016 whilst 69.2% of the papers were published after 2000. Ten spine journals published only 23.4% of the sample. 'Clinical Neurology', 'Orthopedics', 'Neurosciences', and 'Surgery' was the most prolific subject categories. The top citation classic was a paper by van der Linden et al. on ankylosing spondylitis. CONCLUSIONS: The optimal design of research sample made it possible to obtain nearly 13 times the size of the sample in Wei et al. as a true representation of the research in spine through the use of an optimal keyword set for the titles of both papers and 10 spine journals. However, despite the inefficient design of the incentive structures for the relevant stakeholders, the research in spine had expanded 6.8 times since 1980. PMID- 29196945 TI - Pain in Platin-Induced Neuropathies: A Systematic Review and Meta-Analysis. AB - INTRODUCTION: Platin-induced peripheral neuropathy (PIPN) is a common cause of PN in cancer patients. The aim of this paper is to systematically review the current literature regarding PIPN, with a particular focus on epidemiological and clinical characteristics of painful PIPN, and to discuss relevant management strategies. METHODS: A systematic computer-based literature search was conducted on the PubMed database. RESULTS: This search strategy resulted in the identification of 353 articles. After the eligibility assessment, 282 articles were excluded. An additional 24 papers were identified by scanning the reference lists. In total, 95 papers met the inclusion criteria and were used for this review. The prevalence of neuropathic symptoms due to acute toxicity of oxaliplatin was estimated at 84.6%, whereas PN established after chemotherapy with platins was estimated at 74.9%. Specifically regarding pain, the reported prevalence of pain due to acute toxicity of oxaliplatin was estimated at 55.6%, whereas the reported prevalence of chronic peripheral neuropathic pain in PIPN was estimated at 49.2%. CONCLUSION: Peripheral neuropathy is a common complication in patients receiving platins and can be particularly painful. There is significant heterogeneity among studies regarding the method for diagnosing peripheral neuropathy. Nerve conduction studies are the gold standard and should be performed in patients receiving platins and complaining of neuropathic symptoms post-treatment. PMID- 29196947 TI - Effect of bleaching agent extracts on murine macrophages. AB - OBJECTIVES: The aim of this study was to evaluate the cytotoxicity and the influence of bleaching agents on immunologically cell surface antigens of murine macrophages in vitro. MATERIALS AND METHODS: RAW 264.7 cells were exposed to bleaching gel extracts (40% hydrogen peroxide or 20% carbamide peroxide) and different H2O2 concentrations after 1 and 24-h exposure periods and 1-h exposure and 23-h recovery. Tests were performed with and without N-acetyl cysteine (NAC) and buthionine sulfoximine (BSO). Cell viability was determined by MTT assay. The expression of surface markers CD14, CD40, and CD54 with and without LPS stimulation was detected by flow cytometry, while the production of TNF-alpha was measured by ELISA. Statistical analysis was performed using the Mann-Whitney U test (alpha = 0.05). RESULTS: Extracts of bleaching agents were cytotoxic for cells after a 1-h exposure; cells could not recover after 24 h. This effect can be mitigated by the antioxidant NAC and increased by BSO, an inhibitor of glutathione (GSH) synthesis. LPS stimulated expression of all surface markers and TNF-alpha production. Exposure to bleaching agent extracts and H2O2 leads to a reduction of TNF-alpha, CD14, and CD40 expression, while the expression of CD54 was upregulated at non-cytotoxic concentrations. Whereas NAC reduced this effect, it was increased in the presence of BSO. CONCLUSIONS: Extracts of bleaching agents were irreversibly cytotoxic to macrophages after a 1-h exposure. Only the expression of CD54 was upregulated. The reactions are mediated by the non enzymatic antioxidant GSH. CLINICAL RELEVANCE: The addition of an antioxidant can downregulate unfavorable effects of dental bleaching. PMID- 29196948 TI - Fracture behavior of all-ceramic, implant-supported, and tooth-implant-supported fixed dental prostheses. AB - OBJECTIVES: In vitro investigation of the effects of fixed dental prosthesis (FDP) support and loading conditions on the fracture behavior of all-ceramic, zirconia-based FDP veneered with computer-aided design/computer-aided manufacturing (CAD/CAM)-manufactured lithium disilicate ceramic. MATERIALS AND METHODS: Based on a model for a 3-unit FDP in the molar region (tooth in region 15, implant in region 17), 16 identical zirconia frameworks were fabricated and veneered with milled lithium disilicate ceramic. Another 16 FDPs were manufactured similarly, using a model in which the tooth was replaced by an implant. The specimens underwent 10,000 thermal cycles between 6.5 and 60 degrees C and 1,200,000 chewing cycles with a force magnitude of 100 N. All were then subsequently loaded until fracture in a universal testing device. Half of the FDPs were subjected to centric and axial loading on the pontic, the others to eccentric and oblique loading on one cusp of the pontic. RESULTS: No failures were observed after artificial aging. Fracture loads of tooth-implant-supported restorations were 1636 +/- 158 and 1086 +/- 156 N for axial and oblique loading, respectively; implant-supported FDPs fractured at 1789 +/- 202 and 1200 +/- 68 N, respectively. Differences were significant for load application (P < 0.001) and support type (P = 0.020). For the two types of load application, fracture mode differed substantially: complete fracture was observed for centric and axial loading whereas mixed cohesive/adhesive failure was observed for many FDPs loaded eccentrically and obliquely. CONCLUSIONS: The high incidence of chipping of manually veneered implant-supported all-ceramics restorations might be reduced by use of CAD/CAM-manufactured lithium disilicate veneers. CLINICAL RELEVANCE: FDPs veneered with lithium disilicate resist occlusal forces of 500 N, irrespective of load application and support type. The fracture resistance of implant-supported FDPs was, however, higher than that of combined tooth-implant-supported FDPs. Their clinical use seems to be justified. PMID- 29196949 TI - Accuracy and eligibility of CBCT to digitize dental plaster casts. AB - OBJECTIVES: Software-based dental planning requires digital casts and oftentimes cone-beam computed tomography (CBCT) radiography. However, buying a dedicated model digitizing device can be expensive and might not be required. The present study aimed to assess whether digital models derived from CBCT and models digitized using a dedicated optical device are of comparable accuracy. MATERIAL AND METHODS: A total of 20 plaster casts were digitized with eight CBCT and five optical model digitizers. Corresponding models were superimposed using six control points and subsequent iterative closest point matching. Median distances were calculated among all registered models. Data were pooled per scanner and model. Boxplots were generated, and the paired t test, a Friedman test, and a post-hoc Nemenyi test were employed for statistical comparison. Results were found significant at p < 0.05. RESULTS: All CBCT devices allowed the digitization of plaster casts, but failed to reach the accuracy of the dedicated model digitizers (p < 0.001). Median distances between CBCT and optically digitized casts were 0.064 + - 0.005 mm. Qualitative differences among the CBCT systems were detected (chi 2 = 78.07, p < 0.001), and one CBCT providing a special plaster cast digitization mode was found superior to the competitors (p < 0.05). CONCLUSION: CBCT systems failed to reach the accuracy from optical digitizers, but within the limits of the study, accuracy appeared to be sufficient for digital planning and forensic purposes. CLINICAL RELEVANCE: Most CBCT systems enabled digitization of plaster casts, and accuracy was found sufficient for digital planning and storage purposes. PMID- 29196950 TI - Transcriptome analysis of Pseudomonas sp. from subarctic tundra soil: pathway description and gene discovery for humic acids degradation. AB - Although humic acids (HA) are involved in many biological processes in soils and thus their ecological importance has received much attention, the degradative pathways and corresponding catalytic genes underlying the HA degradation by bacteria remain unclear. To unveil those uncertainties, we analyzed transcriptomes extracted from Pseudomonas sp. PAMC 26793 cells time-dependently induced in the presence of HA in a lab flask. Out of 6288 genes, 299 (microarray) and 585 (RNA-seq) were up-regulated by > 2.0-fold in HA-induced cells, compared with controls. A significant portion (9.7% in microarray and 24.1% in RNA-seq) of these genes are predicted to function in the transport and metabolism of small molecule compounds, which could result from microbial HA degradation. To further identify lignin (a surrogate for HA)-degradative genes, 6288 protein sequences were analyzed against carbohydrate-active enzyme database and a self-curated list of putative lignin degradative genes. Out of 19 genes predicted to function in lignin degradation, several genes encoding laccase, dye-decolorizing peroxidase, vanillate O-demethylase oxygenase and reductase, and biphenyl 2,3-dioxygenase were up-regulated > 2.0-fold in RNA-seq. This induction was further confirmed by qRT-PCR, validating the likely involvement of these genes in the degradation of HA. PMID- 29196951 TI - Behavioral and Biochemical Effects of N-Acetylcysteine in Zebrafish Acutely Exposed to Ethanol. AB - Alcohol hangover refers to unpleasant symptoms experienced as a direct consequence of a binge drinking episode. The effects observed in this condition are related to the increase in alcohol metabolites and imbalance in oxidative status. N-acetylcysteine (NAC) is a mucolytic agent and an antidote for paracetamol overdose. Preclinical and clinical studies have shown that NAC is a multi-target drug acting through neuroprotective, antioxidant and neurotrophic mechanisms as well as a glutamate modulator. The aim of this study was to investigate the effects of NAC in zebrafish acutely exposed to ethanol (EtOH). Animals pretreated or not with NAC (1 mg/L, 10 min) were exposed for 60 min to standard tank water (EtOH-) or to 1% EtOH (EtOH+) to evaluate anxiety-like behavior and locomotion in the novel tank test and oxidative damage in the brain. Zebrafish (Danio rerio) exposed to EtOH displayed a decrease in the distance traveled, crossings, entries and time spent in the top area in the novel tank test. Exposure to EtOH also caused oxidative damage, shown by increased lipid peroxidation, decreased non-protein thiols and increased production of reactive oxygen species (DCF assay). NAC prevented both the behavioral alterations and the oxidative stress observed in EtOH+ animals. Given the effects of NAC in preventing the acute behavioral and biochemical effects of EtOH, additional studies are warranted to further investigate the basis of its anecdotal use to prevent hangover. PMID- 29196952 TI - Fabrication and Characterization of Electrospun Bi-Hybrid PU/PET Scaffolds for Small-Diameter Vascular Grafts Applications. AB - In spite of advances have been made during the past decades, the problems associated with small-diameter vascular grafts, including low patency and compliance mismatch and in consequence of that thrombosis, aneurysm and intimal hyperplasia are still challenges. To address these problems, net polyurethane (PU) and poly (ethylene terephthalate) (PET) polymers and hybrid PU/PET were electrospun to create three different types of small-diameter vascular scaffolds due to their unique physicochemical characteristics: PU, PET, and novel hybrid PU/PET scaffolds. The results show that the PU and PET composite can improve the mechanical properties of the tissue-engineered vascular scaffolds in the range of the native vessels where the non-cytotoxicity characteristic of these well-known polymers is still immutable. The compliance and stiffness factor of the fabricated hybrid scaffolds were 4.468 +/- 0.177 and 22.718 +/- 0.896%/0.01 mmHg, respectively, which were significantly different with that of the net PU and PET electrospun scaffolds. Other properties such as ultimate tensile stress (UTS) (3.56 +/- 1.21 MPa) were also in good accordance with the native vessels. Furthermore, FT-IR analysis testified the presence of both PU and PET in the hybrid scaffolds. Overall, we were able to fabricate a hybrid scaffold as a small diameter vascular graft that mechanically matched the gold standard of blood vessel substitution. PMID- 29196954 TI - Prevalence of Human Parainfluenza Viruses and Noroviruses Genomes on Office Fomites. AB - The aim of this study was to evaluate the potential role of office fomites in respiratory (human parainfluenza virus 1-HPIV1, human parainfluenza virus 3 HPIV3) and enteric (norovirus GI-NoV GI, norovirus GII-NoV GII) viruses transmission by assessing the occurrence of these viruses on surfaces in office buildings. Between 2016 and 2017, a total of 130 surfaces from open-space and non open-space rooms in office buildings located in one city were evaluated for HPIV1, HPIV3, NoV GI, and NoV GII viral RNA presence. Detection of viruses was performed by RT-qPCR method. Study revealed 27 positive samples, among them 59.3% were HPIV3-positive, 25.9% HPIV1-positive, and 14.8% NoV GII-positive. All tested surfaces were NoV GI-negative. Statistical analysis of obtained data showed that the surfaces of office equipment including computer keyboards and mice, telephones, and desktops were significantly more contaminated with respiratory viruses than the surfaces of building equipment elements such as door handles, light switches, or ventilation tracts (chi 2 p = 0.006; Fisher's Exact p = 0.004). All examined surfaces were significantly more contaminated with HPIVs than NoVs (chi 2 p = 0.002; Fisher's Exact p = 0.003). Office fomites in open space rooms were more often contaminated with HPIVs than with NoVs (chi 2 p = 0.016; Fisher's Exact p = 0.013). The highest average concentration of HPIVs RNA copies was observed on telephones (1.66 * 102 copies/100 cm2), while NoVs on the light switches (1.40 * 102 copies/100 cm2). However, the Kruskal-Wallis test did not show statistically significant differences in concentration levels of viral RNA copies on surfaces between the all tested samples. This study unequivocally showed that individuals in office environment may have contact with both respiratory and enteric viral particles present on frequently touched surfaces. PMID- 29196955 TI - Simple linear brainstem MRI measurements in the differential diagnosis of progressive supranuclear palsy from the parkinsonian variant of multiple system atrophy. AB - Differential diagnosis of progressive supranuclear palsy (PSP) and the parkinsonian variant of multiple system atrophy (MSA-P) from Parkinson's disease (PD) can be difficult, particularly in atypical cases or early in the disease course. The Magnetic Resonance Parkinsonism Index (MRPI) utilizes linear and surface (planimetry) measurements and has been proposed as a dual MRI biomarker, with high values indicative of PSP and low values of MSA. The aim of this study was to examine the utility of simple linear MRI brainstem measurements, without the use of MRI planimetry, in the diagnosis of patients with Parkinsonism and compare them to the MRPI. A total of 51 patients (PSP: 24, MSA-P: 9, PD: 18) and 15 healthy controls were included. Simple linear MRI distances of brainstem structures were measured. These included midbrain and pons diameters as well as superior cerebellar peduncle (SCP) and middle cerebellar peduncle (MCP) widths. All relevant indices, including ratios and products, were also calculated. The SCP by midbrain product (SCP * midbrain) provided improved sensitivity (100 vs. 91%) and identical specificity (98%) for the diagnosis of PSP, compared to the MRPI. Neither the MRPI nor any of the linear measurements were able to discriminate MSA-P from PD. The SCP by midbrain product is a novel, potent MRI biomarker for PSP.

AB - Glaucoma therapy-related ocular surface disease (OSD) is a serious pathology with a broad spectrum of insidious clinical presentations and complex pathogenesis that undermines long-term glaucoma care. Preservatives, especially benzalkonium chloride (BAK), contained in topical intraocular pressure-lowering medications frequently cause or aggravate OSD in glaucoma. Management of these patients is challenging, and to date often empirical due to the scarcity of controlled long term clinical trials. Most of the available data are extracted from case series and retrospective analysis. Preservative-free prostaglandins and prostaglandin/timolol fixed combinations are novel options developed to remove the harmful impact of preservatives, especially BAK, upon ocular tissues. Based on what is currently known on the value of preservative-free antiglaucoma therapies it is tempting to speculate how these new therapies may affect the future medical management of all glaucoma patients. This article provides a comprehensive and critical review of the current literature on preservative-free prostaglandins and preservative-free prostaglandin/timolol fixed combinations. PMID- 29196956 TI - ASPP2 Inhibits the Profibrotic Effects of Transforming Growth Factor-beta1 in Hepatic Stellate Cells by Reducing Autophagy. AB - BACKGROUND: Apoptosis-stimulating protein of p53-2 (ASPP2) is a damage-inducible P53-binding protein that enhances damage-induced apoptosis. Fibrosis is a wound healing response, and hepatic stellate cells (HSCs) are key players in liver fibrogenesis. However, little is known about the relationship between ASPP2 and hepatic fibrosis. AIMS: We investigated the effects of ASPP2 overexpression in HSCs and the role of ASPP2 in mouse liver fibrogenesis. METHODS: Human HSCs (LX-2 cells) were pre-incubated with GFP adenovirus (Ad) or ASPP2 adenovirus (AdASPP2) for 24 h and then treated with or without TGF-beta1. ASPP2+/- and ASPP2+/+ Balb/c mice were used to examine the effects of ASPP2 on liver fibrosis in vivo. ASPP2+/+ Balb/c mice were generated by injecting AdASPP2 into the tail vein of ASPP2 WT Balb/c mice; all mice received intraperitoneal injections of carbon tetrachloride. RESULTS: In this study, ASPP2 was found to markedly inhibit TGF beta1-induced fibrogenic activation of LX-2 cells. Further experiments using an autophagic flux assay confirmed that ASPP2 reduced the fibrogenic activation of LX-2 cells by inhibiting autophagy. Moreover, we found that ASPP2 overexpression attenuated the anti-apoptotic effects of TGF-beta1 in LX-2 cells. The extent of liver fibrosis was markedly reduced in ASPP2+/+ mouse liver tissue compared with control mice; however, in ASPP2+/- mice, hepatic collagen deposition was significantly increased. CONCLUSION: These results suggest that TGF-beta1-induced autophagy is required for the fibrogenic response in LX-2 cells and that ASPP2 may both inhibit TGF-beta1-induced autophagy and decrease liver fibrosis. PMID- 29196957 TI - Phase 1 and pharmacokinetic study of LY3007113, a p38 MAPK inhibitor, in patients with advanced cancer. AB - Background The signaling protein p38 mitogen-activated protein kinase (MAPK) regulates the tumor cell microenvironment, modulating cell survival, migration, and invasion. This phase 1 study evaluated the safety of p38 MAPK inhibitor LY3007113 in patients with advanced cancer to establish a recommended phase 2 dose. Methods In part A (dose escalation), LY3007113 was administered orally every 12 h (Q12H) at doses ranging from 20 mg to 200 mg daily on a 28-day cycle until the maximum tolerated dose (MTD) was reached. In part B (dose confirmation), patients received MTD. Safety, pharmacokinetics, pharmacodynamics, and tumor response data were evaluated. Results MTD was 30 mg Q12H. The most frequent treatment-related adverse events (>10%) were tremor, rash, stomatitis, increased blood creatine phosphokinase, and fatigue. Grade >= 3 treatment-related adverse events included upper gastrointestinal haemorrhage and increased hepatic enzyme, both occurring at 40 mg Q12H and considered dose-limiting toxicities. LY3007113 exhibited an approximately dose-proportional increase in exposure and time-independent pharmacokinetics after repeated dosing. Maximal inhibition (80%) of primary biomarker MAPK-activated protein kinase 2 in peripheral blood mononuclear cells was not reached, and sustained minimal inhibition (60%) was not maintained for 6 h after dosing to achieve a biologically effective dose (BED). The best overall response in part B was stable disease in 3 of 27 patients. Conclusions The recommended phase 2 dosage of LY3007113 was 30 mg Q12H. Three patients continued treatment after the first radiographic assessment, and the BED was not achieved. Further clinical development of this compound is not planned as toxicity precluded achieving a biologically effective dose. PMID- 29196958 TI - Surgical management of complicated rectovaginal fistulas and the role of omentoplasty. AB - BACKGROUND: Patients with rectovaginal fistulas have a significantly reduced quality of life. Therefore, surgical therapy is often needed even in palliative cases. The aim of the present study was to perform an analysis of the results of the different treatment options available today. METHODS: We performed a retrospective analysis of patients who underwent treatment for rectovaginal fistulas at the Department of Surgery, University of Schleswig-Holstein, Campus Luebeck and the Department of Surgery, WKK Heide, between January 2000 and September 2016. Complication and recurrence rate were retrospectively evaluated. The median follow-up period was 13 months (range 3-36 months). RESULTS: During the observation period, 58 patients underwent surgery (53 curative, 5 palliative) for rectovaginal fistulas. All patients who underwent curative surgery had an omentoplasty, and 39 of 53 (73.6%) patients underwent a resection. Thirty of 39 (77.0%) resections were low anterior resection, while non-continence-preserving resection included subtotal colectomy (n = 5), pelvic exenteration (n = 2), and proctectomy (n = 2). The fistulas were mainly secondary to inflammatory bowel disease (n = 18) or diverticulitis (n = 13), while 19 fistulas were a complication of different cancers or precancerous lesions. The median follow-up time was 13 months (range 6-36). Four patients (6.9%) had fistula recurrence (3 recurrences after low anterior resection, 1 after primary fistula closure). The mortality rate was 6.9% (n = 4). CONCLUSIONS: Non-resecting methods should be used only in uncomplicated fistulas. Rectovaginal fistulas secondary to inflammatory or malignant disease mostly require extensive therapy. Omentoplasty is effective for the treatment of both high and low rectovaginal fistulas. PMID- 29196959 TI - Right colic artery anatomy: a systematic review of cadaveric studies. AB - BACKGROUND: Complete mesocolic excision for right-sided colon cancer may offer an oncologically superior excision compared to traditional right hemicolectomy through high vascular tie and adherence to embryonic planes during dissection, supported by preoperative scanning to accurately define the tumour lymphovascular supply and drainage. The authors support and recommend precision oncosurgery based on these principles, with an emphasis on the importance of understanding the vascular anatomy. However, the anatomical variability of the right colic artery (RCA) has resulted in significant discord in the literature regarding its precise arrangement. METHODS: We systematically reviewed the literature on the incidence of the different origins of the RCA in cadaveric studies. An electronic search was conducted as per Preferred Reporting Items for Systematic Reviews and Meta-analyses recommendations up to October 2016 using the MESH terms 'right colic artery' and 'anatomy' (PROSPERO registration number CRD42016041578). RESULTS: Ten studies involving 1073 cadavers were identified as suitable for analysis from 211 articles retrieved. The weighted mean incidence with which the right colic artery arose from other parent vessels was calculated at 36.8% for the superior mesenteric artery, 31.9% for the ileocolic artery, 27.7% for the root of the middle colic artery and 2.5% for the right branch of the middle colic artery. In 1.1% of individuals the RCA shared a trunk with the middle colic and ileocolic arteries. The weighted mean incidence of 2 RCAs was 7.0%, and in 8.9% of cadavers the RCA was absent. CONCLUSIONS: This anatomical information will add to the technical nuances of precision oncosurgery in right-sided colon resections. PMID- 29196960 TI - Synergizing community-based forest monitoring with remote sensing: a path to an effective REDD+ MRV system. AB - BACKGROUND: The reliable monitoring, reporting and verification (MRV) of carbon emissions and removals from the forest sector is an important part of the efforts on reducing emissions from deforestation and forest degradation (REDD+). Forest dependent local communities are engaged to contribute to MRV through community based monitoring systems. The efficiency of such monitoring systems could be improved through the rational integration of the studies at permanent plots with the geospatial technologies. This article presents a case study of integrating community-based measurements at permanent plots at the foothills of central Nepal and biomass maps that were developed using GeoEye-1 and IKONS satellite images. RESULTS: The use of very-high-resolution satellite-based tree cover parameters, including crown projected area (CPA), crown density and crown size classes improves salience, reliability and legitimacy of the community-based survey of 0.04% intensity at the lower cost than increasing intensity of the community based survey to 0.14% level (2.5 USD/ha vs. 7.5 USD/ha). CONCLUSION: The proposed REDD+ MRV complementary system is the first of its kind and demonstrates the enhancement of information content, accuracy of reporting and reduction in cost. It also allows assessment of the efficacy of community-based forest management and extension to national scale. PMID- 29196961 TI - alpha7-nAChR Activation Has an Opposite Effect on Healing of Covered and Uncovered Wounds. AB - The alpha7 nicotinic acetylcholine receptor (alpha7-nAChR) is associated with inflammation, re-epithelialization, and angiogenesis in wound healing process. A recent study demonstrated that PNU-282987, a selective agonist of alpha7-nAChR, accelerates the repair of diabetic excisional wounds. Whether alpha7-nAChR activation promotes non-diabetic wounds healing is unknown. The aim of this study was to evaluate the effects of alpha7-nAChR activation on non-diabetic wound healing. The effects were evaluated in two wound models. In the first model, the wound was covered with a semi-permeable transparent dressing. In the second model, the wound was left uncovered. In both models, the mice were randomly assigned to two treatment groups: saline or PNU282987 (25 mice in each group). In covered wounds, we found that alpha7-nAChR activation inhibited re epithelialization, angiogenesis, and epithelial cells proliferation, promoted neo epithelial detachment, and suppressed neutrophil infiltration and the expression of interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF). However, in uncovered wounds, we observed that alpha7-nAChR activation promoted re epithelialization and angiogenesis, inhibited neutrophil infiltration and the expression of high mobility group box (HMGB)-1, epidermal growth factor (EGF), and VEGF. In conclusion, this data demonstrated that alpha7-nAChR activation inhibited wound healing in covered wounds but played an opposite role in uncovered wounds. The opposite effect might be primarily due to inhibition of inflammation. PMID- 29196962 TI - The Moral Injury Symptom Scale-Military Version. AB - The purpose of this study was to develop a multi-dimensional measure of moral injury symptoms that can be used as a primary outcome measure in intervention studies that target moral injury (MI) in Veterans and Active Duty Military with PTSD. This was a multi-center study of 427 Veterans and Active Duty Military with PTSD symptoms recruited from VA Medical Centers in Augusta, Los Angeles, Durham, Houston, and San Antonio, and from Liberty University in Lynchburg. Internal reliability of the Moral Injury Symptom Scale-Military Version (MISS-M) was examined along with factor analytic, discriminant, and convergent validity. Participants were randomly split into two equal samples, with exploratory factor analysis conducted in the first sample and confirmatory factor analysis in the second. Test-retest reliability was assessed in a subsample of 64 Veterans. The 45-item MISS-M consists of 10 theoretically grounded subscales assessing guilt, shame, moral concerns, religious struggles, loss of religious faith/hope, loss of meaning/purpose, difficulty forgiving, loss of trust, and self-condemnation. The Cronbach's alpha of the overall scale was .92 and of individual subscales ranged from .56 to .91. The test-retest reliability was .91 for the total scale and ranged from .78 to .90 for subscales. Discriminant validity was demonstrated by relatively weak correlations with other psychosocial, religious, and physical health constructs, and convergent validity was indicated by strong correlations with PTSD, depression, and anxiety symptoms. The MISS-M is a reliable and valid multi-dimensional symptom measure of moral injury that can be used in studies targeting MI in Veterans and Active Duty Military with PTSD symptoms and may also be used by clinicians to identify those at risk. PMID- 29196963 TI - Serum lipid and bone metabolism effects of Toremifene vs. Letrozole as adjuvant therapy for postmenopausal early breast cancer patients: results of a multicenter open randomized study. AB - A prospective randomized phase II trial was conducted to evaluate the time course effects of toremifene (TOR) and letrozole (LET), as adjuvant hormone therapy, on serum lipid profiles and bone metabolism in estrogen receptor (ER)-positive, postmenopausal breast cancer patients.Fifty-four postmenopausal breast cancer patients [ER positive, HER2 negative, T1-2, node metastases (n = 0-3), M0] who had undergone curative resection were enrolled. They were randomized to receive either TOR 40 mg/day or LET 2.5 mg/day as adjuvant hormone therapy. Serum lipids and bone markers were measured prior to, and again at 6, 12, and 24 months after initiation of treatment. Changes in serum lipids and bone markers were compared. Serum levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) were decreased compared with the baseline values at 6 months in 6.5 and 14.0% of patients, respectively, receiving TOR. Lipid levels did not change in patients administered LET. Significant differences were observed in TC and LDL-C between the two groups at 12 and 24 months. In the TOR group, serum bone-specific alkaline phosphatase (BAP) was decreased by 25.0% at 12 months, and serum cross linked N-telopeptide of type-I collagen (NTx) was decreased by 13.6% at 6 months, and these reductions were maintained for at least 24 months. In contrast, in the LET group, serum BAP did not change and NTx was increased by 16.0% at 6 months and by 18.6% at 24 months, as compared with the baseline.TOR and LET exert different effects on serum lipid profiles and bone metabolism markers. The effects of TOR, as adjuvant hormone therapy, on both lipids and bone metabolism in postmenopausal breast cancer patients are superior to those of LET. PMID- 29196965 TI - Metabolomic prediction of treatment outcome in pancreatic ductal adenocarcinoma patients receiving gemcitabine. AB - PURPOSE: Resistance to gemcitabine remains a key challenge in the treatment of pancreatic ductal adenocarcinoma (PDAC), necessitating the constant search for effective strategies for a priori prediction of clinical outcome. While the existing studies focused on aberration of drug disposition genes and proteins as molecular predictors of gemcitabine treatment outcomes, the metabolic aberration associated with chemoresistance in clinical PDAC has been neglected. This exploratory study investigated the potential role of tissue metabolomics in characterizing the clinical treatment outcome of gemcitabine therapy. METHODS: Surgically resected tumors from PDAC patients who underwent gemcitabine-based adjuvant chemotherapy (n = 25) were subjected to metabotyping using gas chromatography/time-of-flight mass spectrometry (GC/TOFMS). RESULTS: A partial least-squares discriminant analysis (PLS-DA) model clearly distinguished patients who had favorable survival [overall survival (OS) > 24 months] from those who exhibited poorer survival (OS < 16 months) (Q 2 = 0.302). Receiver-operating characteristic analysis demonstrated the robustness of the PLS-DA model with an area under the curve of 1. PLS-DA revealed 19 marker metabolites (e.g., lactic acid, proline, and pyroglutamate) that shed insights into the chemoresistance of gemcitabine in PDAC. Particularly, tissue levels of lactic acid complemented transcript expression levels of human equilibrative nucleoside transporter 1 in distinguishing patients according to their overall survival. CONCLUSION: This work established proof-of-principle for GC/TOFMS-based global metabotyping of PDAC and laid the foundation for future discovery of metabolic biomarkers predictive of gemcitabine resistance in PDAC chemotherapy. PMID- 29196964 TI - The earlier, the better: the effects of different administration timepoints of sorafenib in suppressing the carcinogenesis of VEGF in rats. AB - PURPOSE: To investigate the optimal starting time point of sorafenib therapy in suppressing the tumor-promoting effects of VEGF up-regulation, which is frequently found after local therapy in clinical practice. METHODS: VEGF was intravenously injected to imitate the evaluated expression after local tumor therapy, such as TACE. A total of 40 SD rats bearing hepatic tumors were randomly divided into four groups and sorafenib was administered at different timepoints: (A) control group: VEGF injection only; (B) initiating sorafenib 72 h prior to VEGF injection; (C) initiating sorafenib simultaneously with VEGF injection; (D) initiating sorafenib 72 h post-VEGF injection. The rate of tumor growth, median survival time, expression of VEGF, and microvessel density (MVD), as determined by immunohistochemical (IHC) examination, were compared. RESULTS: The results revealed that the tumor size and median survival time were significantly different between the three sorafenib groups compared to the control group (p < 0.05). Median survival times were 19.6 +/- 1.78, 31.2 +/- 6.99, 27.4 +/- 4.9, and 26.5 +/- 4.6 days in group A, B, C, and D, respectively. Furthermore, there was a difference in statistical significance between the two sorafenib groups B and D (p = 0.04). Tumors were collected for HE staining and IHC examination. The expression levels of VEGF in B, C, and D were 42.8 +/- 7.96, 71.9 +/- 15.73, and 73.6 +/- 13.73, and all of them were significantly lower than that in the control group (88.3 +/- 13.61). Furthermore, the level of MVD was 109.2 +/- 8.98 in the control group, which was significantly higher than in the three sorafenib groups (45.7 +/- 16.92, 77.1 +/- 16.29, and 93.6 +/- 12.87, all p < 0.05). CONCLUSIONS: According to our results, the most suitable regimen for the administration of sorafenib is before the increased expression of VEGF, which showed a potential advantage for controlling the tumor growth and prolonging the survival time of test animal via inhibiting VEGF-receptor expression through the bifunction of VEGF, and the reduction of tumor angiogenesis. PMID- 29196966 TI - Controlling futures? Online Genetic Testing and Neurodegenerative Disease : Comment on "Personal Genomic Testing, Genetic Inheritance, and Uncertainty". AB - Online personalized genetic testing services offer accessible and convenient options for satisfying personal curiosity about health and obtaining answers about one's genetic provenance. They are especially attractive to healthy people who wish to learn about their future risk of disease, as Paul Mason's (2017) case study of "Jordan" illustrates. In this response, we consider how online genetic testing services are used by people diagnosed with a common neurodegenerative disease, Parkinson's disease, to gain a sense of certainty regarding the future. PMID- 29196968 TI - NK cell therapy after hematopoietic stem cell transplantation: can we improve anti-tumor effect? AB - After decades since the discovery of natural killer (NK) cells as potential effector cells fighting malignantly transformed and virally infected cells, little progress has been made in their clinical application. This yet unrealized therapeutic effect is presumably, at least in part, due to low numbers of functional NK cells that could be obtained from the peripheral blood relative to tumor burden. Our group hypothesized that a relatively small NK cell number to targeted malignant cells is the cause of a lack of clinical effect. We pursued obtaining large numbers of NK cells via ex vivo expansion using feeder cells that express membrane-bound IL-21. Early clinical studies demonstrate safety of administration of ex vivo expanded NK cells after transplantation using this method and suggest a therapeutic benefit in terms on decreasing relapse rate and possible control of viral infections post-transplant can be achieved. Successful application of NK cells after hematopoietic stem cell transplantation opens the possibility to effectively enhance the anti-tumor effect and decrease relapse rate post-transplant. Moreover, high doses of NK cells could prove more efficacious in enhancing anti-tumor effects, not only in hematological malignancies, with our without transplantation, but also in solid tumor oncology. PMID- 29196969 TI - Rapid and reliable protein structure determination via chemical shift threading. AB - Protein structure determination using nuclear magnetic resonance (NMR) spectroscopy can be both time-consuming and labor intensive. Here we demonstrate how chemical shift threading can permit rapid, robust, and accurate protein structure determination using only chemical shift data. Threading is a relatively old bioinformatics technique that uses a combination of sequence information and predicted (or experimentally acquired) low-resolution structural data to generate high-resolution 3D protein structures. The key motivations behind using NMR chemical shifts for protein threading lie in the fact that they are easy to measure, they are available prior to 3D structure determination, and they contain vital structural information. The method we have developed uses not only sequence and chemical shift similarity but also chemical shift-derived secondary structure, shift-derived super-secondary structure, and shift-derived accessible surface area to generate a high quality protein structure regardless of the sequence similarity (or lack thereof) to a known structure already in the PDB. The method (called E-Thrifty) was found to be very fast (often < 10 min/structure) and to significantly outperform other shift-based or threading based structure determination methods (in terms of top template model accuracy) with an average TM-score performance of 0.68 (vs. 0.50-0.62 for other methods). Coupled with recent developments in chemical shift refinement, these results suggest that protein structure determination, using only NMR chemical shifts, is becoming increasingly practical and reliable. E-Thrifty is available as a web server at http://ethrifty.ca . PMID- 29196967 TI - Modern iron replacement therapy: clinical and pathophysiological insights. AB - Iron deficiency, with or without anemia, is extremely frequent worldwide, representing a major public health problem. Iron replacement therapy dates back to the seventeenth century, and has progressed relatively slowly until recently. Both oral and intravenous traditional iron formulations are known to be far from ideal, mainly because of tolerability and safety issues, respectively. At the beginning of this century, the discovery of hepcidin/ferroportin axis has represented a turning point in the knowledge of the pathophysiology of iron metabolism disorders, ushering a new era. In the meantime, advances in the pharmaceutical technologies are producing newer iron formulations aimed at minimizing the problems inherent with traditional approaches. The pharmacokinetic of oral and parenteral iron is substantially different, and diversities have become even clearer in light of the hepcidin master role in regulating systemic iron homeostasis. Here we review how iron therapy is changing because of such important advances in both pathophysiology and pharmacology. PMID- 29196970 TI - Endocannabinoid hydrolases in avian HD11 macrophages identified by chemoproteomics: inactivation by small-molecule inhibitors and pathogen-induced downregulation of their activity. AB - The endocannabinoids (eCBs) are endogenous arachidonoyl-containing lipid mediators with important roles in host defense. Macrophages are first-line defenders of the innate immune system and biosynthesize large amounts of eCBs when activated. The cellular levels of eCBs are controlled by the activities of their biosynthetic enzymes and catabolic enzymes, which include members of the serine hydrolase (SH) superfamily. The physiologic activity of SHs can be assessed in a class-specific way using chemoproteomic activity-based protein profiling (ABPP) methods. Here, we have examined avian (chicken) HD11 macrophages, a widely used cell line in host-pathogen research, using gel-based ABPP and ABPP-multidimensional protein identification technology (MudPIT) to profile the changes in SH activities under baseline, chemical-inhibitor-treated, and pathogen-challenged conditions. We identified alpha/beta-hydrolase domain 6 (ABHD6) and fatty acid amide hydrolase (FAAH) as the principal SHs responsible for 2-arachidonoylglycerol (2AG) hydrolysis, thereby regulating the concentration of this lipid in HD11 cells. We further discovered that infection of HD11 macrophages by Salmonella Typhimurium caused the activities of these 2AG hydrolases to be downregulated in the host cells. ABHD6 and FAAH were potently inhibited by a variety of small-molecule inhibitors in intact live cells, and thus these compounds might be useful host-directed adjuvants to combat antimicrobial resistance in agriculture. 2AG was further shown to augment the phagocytic function of HD11 macrophages, which suggests that pathogen-induced downregulation of enzymes controlling 2AG hydrolytic activity might be a physiological mechanism to increase 2AG levels, thus enhancing phagocytosis. Together these results define ABHD6 and FAAH as 2AG hydrolases in avian macrophages that can be inactivated pharmacologically and decreased in activity during Salmonella Typhimurium infection. PMID- 29196971 TI - Tomatidine inhibits tumor necrosis factor-alpha-induced apoptosis in C2C12 myoblasts via ameliorating endoplasmic reticulum stress. AB - In this study, we examined the effect of tomatidine on tumor necrosis factor (TNF)-alpha-induced apoptosis in C2C12 myoblasts. TNF-alpha treatment increased cleaved caspase 3 and cleaved poly (ADP-ribose) polymerase (PARP) protein levels in a dose- and time-dependent manner. Pretreatment of cells with 10 MUM tomatidine prevented TNF-alpha-induced apoptosis, caspase 3 cleavage, and PARP cleavage. Cells were treated with 100 ng/mL TNF-alpha for 24 h, and flow cytometry was utilized to assess apoptosis using annexin-V and 7-aminoactinomycin D. TNF-alpha up-regulated activating transcription factor 4 (ATF4) and C/EBP homologous protein (CHOP) expression. This effect was suppressed by pretreatment with tomatidine. Pretreatment with 4-phenylbutyric acid (a chemical chaperone) also inhibited TNF-alpha-induced cleavage of caspase 3 and PARP and up-regulation of ATF4 and CHOP expression. In addition, tomatidine-mediated inhibition of phosphorylation of c-Jun amino terminal kinase (JNK) attenuated TNF-alpha-induced cleavage of PARP and caspase 3. However, tomatidine did not affect NF-kappaB activation in TNF-alpha-treated C2C12 myoblast cells. Taken together, the present study demonstrates that tomatidine attenuates TNF-alpha-induced apoptosis through down-regulation of CHOP expression and inhibition of JNK activation. PMID- 29196972 TI - Proximal total splenic artery embolization for refractory hepatic encephalopathy. AB - A Japanese woman with a history of Kasai operation for biliary atresia had living donor liver transplantation at the age of 22. The first episode of refractory HE and late cellular rejection was treated by a high dose of methylprednisolone. The second episode of refractory HE was treated by balloon-occluded retrograde transvenous obliteration for a spleno-renal shunt. However, the third episode of refractory HE occurred 11 years after liver transplantation. The liver cirrhosis and hypersplenism were present with a Child-Pugh score of C-10. Although portal vein flow was hepatopetal, superior mesenteric vein flow regurgitated. We performed proximal total splenic artery embolization (TSAE). Superior mesenteric vein flow changed to a hepatopetal direction and she became clear. At a year after proximal TSAE, her spleen volume had decreased to 589 mL (20% decrease) on computed tomography. She is well and has a Child-Pugh score of 8 without overt HE. We report the first case of refractory HE treated by proximal TSAE that is a possible less invasive treatment option for a selected patient. PMID- 29196973 TI - A Novel Homozygous Mutation in SPTBN2 Leads to Spinocerebellar Ataxia in a Consanguineous Family: Report of a New Infantile-Onset Case and Brief Review of the Literature. AB - The objective of this study was the identification of likely genes and mutations associated with an autosomal recessive (AR) rare spinocerebellar ataxia (SCA) phenotype in two patients with infantile onset, from a consanguineous family. Using genome-wide SNP screening, autozygosity mapping, targeted Sanger sequencing and nextgen sequencing, family segregation analysis, and comprehensive neuropanel, we discovered a novel mutation in SPTBN2. Next, we utilized multiple sequence alignment of amino acids from various species as well as crystal structures provided by protein data bank (PDB# 1WYQ and 1WJM) to model the mutation site and its effect on beta-III-spectrin. Finally, we used various bioinformatic classifiers to determine pathogenicity of the missense variant. A comprehensive clinical and diagnostic workup including radiological exams were performed on the patients as part of routine patient care. The homozygous missense variant (c.1572C>T; p.R414C) detected in exon 2 was fully segregated in the family and absent in a large ethnic cohort as well as publicly available data sets. Our comprehensive targeted sequencing approaches did not reveal any other likely candidate variants or mutations in both patients. The two male siblings presented with delayed motor milestones and cognitive and learning disability. Brain MRI revealed isolated cerebellar atrophy more marked in midline inferior vermis at ages of 3 and 6.5 years. Sequence alignments of the amino acids for beta-III-spectrin indicated that the arginine at 414 is highly conserved among various species and located towards the end of first spectrin repeat domain. Inclusive bioinformatic analysis predicted that the variant is to be damaging and disease causing. In addition to the novel mutation, a brief literature review of the previously reported mutations as well as clinical comparison of the cases were also presented. Our study reviews the previously reported SPTBN2 mutations and cases. Moreover, the novel mutation, p.R414C, adds up to the literature for the infantile-onset form of autosomal recessive ataxia associated with SPTBN2. Previously, few SPTBN2 recessive mutations have been reported in humans. Animal models especially the beta-III-/- mouse model provided insights into early coordination and gait deficit suggestive of loss-of-function. It is expected to see more recessive SPTBN2 mutations appearing in the literature during the upcoming years.

AB - Gadolinium (Gd)-based contrast agents (GBCAs) are used in magnetic resonance imaging (MRI) to increase the diagnostic yield. Current reports using animal models or human subjects have shown that GBCAs may be deposited in brain including the cerebellum. Although further studies may be required to clarify the toxicity of GBCAs, we should be more cautious to use these agents particularly in patients who more likely to have repeated enhanced MRI along their lifespan. In this editorial, current studies to clarify the toxicity of GBCAs in the cerebellum are introduced. PMID- 29196975 TI - Paradoxical Activation in the Cerebellum During Language fMRI in Patients with Brain Tumors: Possible Explanations Based on Neurovascular Uncoupling and Functional Reorganization. AB - The cerebellum is known for its crossed activation pattern with the contralateral cerebral hemisphere during language functional magnetic resonance imaging (fMRI) tasks in healthy patients. Crossed cerebro-cerebellar activation has been previously shown to occur in patients with brain tumors not affecting the activation areas. However, the presence of a tumor in left Broca's area in the inferior frontal gyrus is known to disrupt cerebral activation during language tasks. This study investigated if crossed cerebro-cerebellar activation patterns for language tasks would still occur in such patients. A total of 43 right-handed patients with a glioma affecting left Broca's area were examined for their cerebral and cerebellar activation during an fMRI language task. Only 13 of the 43 patients exhibited crossed cerebro-cerebellar activation patterns. Statistically significant differences of atypical cerebro-cerebellar activation patterns were found between cerebral right-dominant (RD) and cerebral co-dominant (CD) (p < 0.001) as well as cerebral RD and cerebral left-dominant (LD) patients (p < 0.01), while no differences were found when patients were divided based on cerebellar dominance (p > 0.75) or tumor grade (p > 0.5). No relation was found between the cerebellar and cerebral laterality index (LI) values (rho = - 0.20; p = 0.21). Atypical activation patterns are suspected to have been caused by the tumor, perhaps a result of contralateral reorganization in some cases and false negative activation in left Broca's area from neurovascular uncoupling (NVU) in others. Cerebellar activation may also potentially indicate cerebral false negative behavior and future cerebral contralateral reorganization.

AB - Mutations in the inositol 1,4,5-triphosphate receptor type 1 gene (ITPR1) lead to SCA15, SCA16, and SCA29. To date, only a few families with SCA29 have been reported. A three-generation Chinese family including four affected persons and two unaffected persons were enrolled in this study. We conducted whole-exome sequencing (WES) of the proband DNA initially to find the causal gene. We ascertained the family with autosomal dominant type of congenital nonprogressive cerebellar ataxia (CNPCA) associated with delayed motor and cognitive impairment. WES study was performed with two patients and identified c.1207-2A-T transition, in exon 14 of ITPR1, which was a splicing mutation. Sanger sequencing showed that four patients within this family carried the mutation and two unaffected members did not carry it. The results showed that the novel splicing mutation of ITPR1 was the causative gene for SCA29. In conclusion, we identified a novel SCA29 causative splicing mutation of ITPR1 in a Chinese family. We suggest ITPR1 gene analysis shall be a priority for diagnosis of patients with early-onset CNPCA. Our study demonstrated that whole-exome sequencing might rapidly improve the diagnosis of genetic ataxias. PMID- 29196977 TI - Self-Organized Cerebellar Tissue from Human Pluripotent Stem Cells and Disease Modeling with Patient-Derived iPSCs. AB - Recent advances in the techniques that differentiate induced pluripotent stem cells (iPSCs) into specific types of cells enabled us to establish in vitro cell based models as a platform for drug discovery. iPSC-derived disease models are advantageous to generation of a large number of cells required for high throughput screening. Furthermore, disease-relevant cells differentiated from patient-derived iPSCs are expected to recapitulate the disorder-specific pathogenesis and physiology in vitro. Such disease-relevant cells will be useful for developing effective therapies. We demonstrated that cerebellar tissues are generated from human PSCs (hPSCs) in 3D culture systems that recapitulate the in vivo microenvironments associated with the isthmic organizer. Recently, we have succeeded in generation of spinocerebellar ataxia (SCA) patient-derived Purkinje cells by combining the iPSC technology and the self-organizing stem cell 3D culture technology. We demonstrated that SCA6-derived Purkinje cells exhibit vulnerability to triiodothyronine depletion, which is suppressed by treatment with thyrotropin-releasing hormone and Riluzole. We further discuss applications of patient-specific iPSCs to intractable cerebellar disease. PMID- 29196978 TI - The Role of Soluble Epoxide Hydrolase Enzyme on Daunorubicin-Mediated Cardiotoxicity. AB - Several studies have demonstrated the role of cytochrome P450 (CYP) and its associated arachidonic acid (AA) metabolites in the anthracyclines-induced cardiac toxicity. However, the ability of daunorubicin (DNR) to induce cardiotoxicity through the modulation of CYP and its associated AA metabolites has not been investigated yet. Therefore, we hypothesized that DNR-induced cardiotoxicity is mediated through the induction of cardiotoxic hydroxyeicosatetraenoic acids and/or the inhibition of cardioprotctive epoxyeicosatrienoic acids (EETs). To test our hypothesis, Sprague-Dawley rats were treated with DNR (5 mg/kg i.p.) for 24 h, whereas human ventricular cardiomyocytes RL-14 cells were exposed to DNR in the presence and absence of 4 [[trans-4-[[(tricyclo[3.3.1.13,7]dec-1-ylamino)carbonyl]amino]cyclohexyl]oxy] benzoic acid (tAUCB), a soluble epoxide hydrolase (sEH) inhibitor. Thereafter, real-time PCR, Western blot analysis and liquid chromatography-electron spray ionization mass spectroscopy were used to determine the level of gene expression, protein expression and AA metabolites, respectively. Our results showed that DNR induced cardiotoxicity in vivo and in vitro as evidenced by the induction of hypertrophic and fibrotic markers. Moreover, the DNR-induced cardiotoxicity was associated with a dramatic increase in the formation of cardiac DHET/EET metabolites both in vivo and in RL-14 cells suggesting a sEH enzyme dependent mechanism. Interestingly, inhibition of sEH using tAUCB, a selective sEH inhibitor, significantly protects against DNR-induced cardiotoxicity. Mechanistically, the protective effect tAUCB was mediated through the induction of P50 nuclear factor-kappaB and the inhibition of phosphorylated p38. In conclusion, our study provides the first evidence that DNR induces cardiotoxicity through a sEH-mediated EETs degradation-dependent mechanism.

PMID- 29196979 TI - Changes in arterial pressure and markers of nitric oxide homeostasis and oxidative stress following surgical correction of hydronephrosis in children. AB - OBJECTIVE: Recent clinical studies have suggested an increased risk of elevated arterial pressure in patients with hydronephrosis. Animals with experimentally induced hydronephrosis develop hypertension, which is correlated to the degree of obstruction and increased oxidative stress. In this prospective study we investigated changes in arterial pressure, oxidative stress, and nitric oxide (NO) homeostasis following correction of hydronephrosis. METHODS: Ambulatory arterial pressure (24 h) was monitored in pediatric patients with hydronephrosis (n = 15) before and after surgical correction, and the measurements were compared with arterial pressure measurements in two control groups, i.e. healthy controls (n = 8) and operated controls (n = 8). Markers of oxidative stress and NO homeostasis were analyzed in matched urine and plasma samples. RESULTS: The preoperative mean arterial pressure was significantly higher in hydronephrotic patients [83 mmHg; 95% confidence interval (CI) 80-88 mmHg] than in healthy controls (74 mmHg; 95% CI 68-80 mmHg; p < 0.05), and surgical correction of ureteral obstruction reduced arterial pressure (76 mmHg; 95% CI 74-79 mmHg; p < 0.05). Markers of oxidative stress (i.e., 11-dehydroTXB2, PGF2alpha, 8-iso PGF2alpha, 8,12-iso-iPF2alpha-VI) were significantly increased (p < 0.05) in patients with hydronephrosis compared with both control groups, and these were reduced following surgery (p < 0.05). Interestingly, there was a trend for increased NO synthase activity and signaling in hydronephrosis, which may indicate compensatory mechanism(s). CONCLUSION: This study demonstrates increased arterial pressure and oxidative stress in children with hydronephrosis compared with healthy controls, which can be restored to normal levels by surgical correction of the obstruction. Once reference data on ambulatory blood pressure in this young age group become available, we hope cut-off values can be defined for deciding whether or not to correct hydronephrosis surgically.

PMID- 29196982 TI - A Brief Instrument to Assess Both Burnout and Professional Fulfillment in Physicians: Reliability and Validity, Including Correlation with Self-Reported Medical Errors, in a Sample of Resident and Practicing Physicians. AB - OBJECTIVE: The objective of this study was to evaluate the performance of the Professional Fulfillment Index (PFI), a 16-item instrument to assess physicians' professional fulfillment and burnout, designed for sensitivity to change attributable to interventions or other factors affecting physician well-being. METHODS: A sample of 250 physicians completed the PFI, a measure of self-reported medical errors, and previously validated measures including the Maslach Burnout Inventory (MBI), a one-item burnout measure, the World Health Organization's abbreviated quality of life assessment (WHOQOL-BREF), and PROMIS short-form depression, anxiety, and sleep-related impairment scales. Between 2 and 3 weeks later, 227 (91%) repeated the PFI and the sleep-related impairment scale. RESULTS: Principal components analysis justified PFI subscales for professional fulfillment, work exhaustion, and interpersonal disengagement. Test-retest reliability estimates were 0.82 for professional fulfillment (alpha = 0.91), 0.80 for work exhaustion (alpha = 0.86), 0.71 for interpersonal disengagement (alpha = 0.92), and 0.80 for overall burnout (alpha = 0.92). PFI burnout measures correlated highly (r >= 0.50) with their closest related MBI equivalents. Cohen's d effect size differences in self-reported medical errors for high versus low burnout classified using the PFI and the MBI were 0.55 and 0.44, respectively. PFI scales correlated in expected directions with sleep-related impairment, depression, anxiety, and WHOQOL-BREF scores. PFI scales demonstrated sufficient sensitivity to detect expected effects of a two-point (range 8-40) change in sleep-related impairment. CONCLUSIONS: PFI scales have good performance characteristics including sensitivity to change and offer a novel contribution by assessing professional fulfillment in addition to burnout.

AB - Identifying a small subset of disease critical genes out of a large size of microarray gene expression data is a challenge in computational life sciences. This paper has applied four meta-heuristic algorithms, namely, honey bee mating optimization (HBMO), harmony search (HS), differential evolution (DE) and genetic algorithm (basic version GA) to find disease critical genes of preeclampsia which affects women during gestation. Two hybrid algorithms, namely, HBMO-kNN and HS kNN have been newly proposed here where kNN (k nearest neighbor classifier) is used for sample classification. Performances of these new approaches have been compared with other two hybrid algorithms, namely, DE-kNN and SGA-kNN. Three datasets of different sizes have been used. In a dataset, the set of genes found common in the output of each algorithm is considered here as disease critical genes. In different datasets, the percentage of classification or classification accuracy of meta-heuristic algorithms varied between 92.46 and 100%. HBMO-kNN has the best performance (99.64-100%) in almost all data sets. DE-kNN secures the second position (99.42-100%). Disease critical genes obtained here match with clinically revealed preeclampsia genes to a large extent. PMID- 29196983 TI - Paper Spray Tandem Mass Spectrometry Based on Molecularly Imprinted Polymer Substrate for Cocaine Analysis in Oral Fluid. AB - This study proposes a new direct and fast method of analysis employing paper spray mass spectrometry (PS-MS). The paper used in the proposed method was modified with molecularly imprinted polymers (MIP) to create a specific site for cocaine analysis in oral fluid. MIP membrane was successfully synthetized and employed. The developed method showed to be linear in a concentration range from LOQ to 100 ng mL-1. The experimental value of LOQ obtained was 1 ng mL-1. The inter-day and intra-day precision and accuracy of the PS-MS method presented values lower than 15%. The total recoveries were also evaluated. The PS-MS method for the analysis of cocaine in oral fluid showed to be very promising and the validation parameters showed a good correlation with the literature. Graphical abstract ?. PMID- 29196985 TI - Virus-Induced Gene Silencing (VIGS) in Aegilops tauschii and Its Use in Functional Analysis of AetDREB2. AB - Among the available reverse genetic approaches for studying gene function, virus induced gene silencing (VIGS) has several advantages. It allows rapid characterization of gene function independent of stable transformation, which is basically difficult to achieve in monocots, and offers the potential to silence individual or multiple genes of a gene family. In order to establish a VIGS system in Aegilops tauschii, modified vectors derived from Barley stripe mosaic virus (BSMV) were used for silencing a phytoene desaturase gene that provides a convenient visual reporter for silencing. The results demonstrated a high efficiency of BSMV-VIGS in A. tauschii. Moreover, the BSMV-VIGS system was used to target a 354 bp specific region of the Dehydration-responsive element-binding (AetDreb2) gene, resulting in successful silencing of the gene in A. tauschii plants, as verified by real-time qRT-PCR. Indeed, in comparison with plants that were inoculated with an empty vector (BSMV:00), a faster rate of wilting and a lower relative water content were observed in plants inoculated with BSMV:AetDreb2 when they were exposed to drought stress. Therefore, BSMV-VIGS can be efficiently employed as a novel tool for reverse genetics in A. tauschii. It can also be used to study the effects of polyploidization on the gene function by a comparative analysis between bread wheat and its diploid progenitor. PMID- 29196986 TI - Over-Expression of AtPAP1 Transcriptional Factor Enhances Phenolic Acid Production in Transgenic Roots of Leonurus sibiricus L. and Their Biological Activities. AB - This study examines the production of five phenolic acids (chlorogenic acid, neochlorogenic acid, ferulic acid, caffeic acid and p-coumaric acid) following over-expression of AtPAP1 transcription factor by four transgenic root clones of Leonurus sibiricus after Agrobacterium rhizogenes transformation. The AtPAP1 expression level was estimated by quantitative real-time PCR. High levels of phenolic acids were found in the transgenic roots of L. sibiricus and were determined by high-performance liquid chromatography-mass spectrometry analysis. Additionally, transgenic roots showed antimicrobial potential and cytotoxic activity on glioma cells in IV grade. Our results suggest that L. sibiricus transformed roots with AtPAP1 gene over-expression may represent a potential source of phenolic acids. PMID- 29196987 TI - Underweight status at diagnosis is associated with poorer outcomes in adult patients with acute myeloid leukemia: a retrospective study of JALSG AML 201. AB - Recent studies have described various impacts of obesity and being overweight on acute myeloid leukemia (AML) outcomes in adult patients, but little is known about the impact of being underweight. We compared the outcomes of underweight patients to those of normal weight and overweight patients. Adult patients with AML who registered in the JALSG AML201 study (n = 1057) were classified into three groups: underweight (body mass index [BMI] < 18.5, n = 92), normal weight (BMI 18.5-25, n = 746), and overweight (BMI >= 25, n = 219). With the exception of age and male/female ratio, patient characteristics were comparable among the three groups. Rates of complete remission following induction chemotherapy were similar among the three groups (p = 0.68). We observed a significant difference in overall survival (OS), disease-free survival (DFS), and non-relapse mortality (NRM) between underweight and normal weight patients (3-year OS 34.8 vs. 47.7%, p = 0.01; DFS 28.6 vs. 39.8%, p = 0.02; 1-year NRM 6.2 vs. 2.6%, p = 0.05), but not between underweight and overweight patients. In multivariate analysis, underweight was an independent adverse prognostic factor for OS (p < 0.01), DFS (p = 0.01), and NRM (p = 0.04). During the first induction chemotherapy, the incidences of documented infection (DI) and severe adverse events (AEs) were higher in underweight patients than those in normal weight patients (DI 16 vs. 8.1%, p = 0.04; AE 36 vs. 24%, p = 0.05). In conclusion, underweight was an independent adverse prognostic factor for survival in adult AML patients. PMID- 29196988 TI - Analysis of Spontaneous Postmarket Case Reports Submitted to the FDA Regarding Thromboembolic Adverse Events and JAK Inhibitors. AB - INTRODUCTION: The Janus kinase (JAK) inhibitor baricitinib is approved in Europe and Japan for the treatment of rheumatoid arthritis. In April 2017, the US FDA expressed concern about thromboembolic events (deep venous thrombosis [DVT] and pulmonary embolism [PE]) observed in placebo-controlled clinical trials of baricitinib. The European and Japanese labels for baricitinib were recently updated to include a precaution related to potential thromboembolic events in patients at risk. Given that the FDA-approved drugs tofacitinib and ruxolitinib are in the same class, we conducted a safety review of the FDA's Adverse Event Reporting System (FAERS) to assess postmarketing reporting rates for related thromboembolic risks. METHODS: Adverse event (AE) data for tofacitinib, tofacitinib extended-release (XR), and ruxolitinib were obtained from the FAERS. Reporting odds ratios (RORs) and the R package 'PhViD' to estimate the empirical Bayesian geometric mean (EBGM) were used to detect AEs with higher-than-expected reporting rates within the FAERS. RESULTS: We did not find evidence in the FAERS for elevated reporting rates for DVT and PE across the three JAK inhibitors we analyzed. However, multiple drug-AE combinations relating to thromboembolic events had both RORs and EBGM values above 1, indicating a trend toward higher than-expected reporting rates. For pulmonary thrombosis, the ROR values for ruxolitinib, tofacitinib, and tofacitinib XR were 1.46 (95% confidence interval [CI] 0.76-2.80), 2.46 (1.55-3.91), and 2.48 (0.80-7.71), respectively, while the EBGM values were 1.25 (0.70), 2.46 (1.64), and 1.56 (0.57), respectively. Ruxolitinib had ROR values of 4.08 (2.25-7.38) and 1.22 (0.97-1.53) for portal vein thrombosis and thrombosis, respectively. The EBGM values for the same drug AE combinations were 3.04 (1.79) and 1.16 (0.96). CONCLUSIONS: Our safety review of postmarketing FAERS reports associated with three FDA-approved JAK inhibitors did not find elevated reporting rates for DVT and PE specifically. However, the FAERS data indicated that pulmonary thrombosis may potentially be a class-wide issue for JAK inhibitors. Portal vein thrombosis may also be a potential risk for ruxolitinib. While these FAERS data add to a growing body of evidence that JAK inhibitors may be contraindicated in patients at risk of thromboembolic events, the data need to be confirmed by future AE reporting trends, analysis of electronic health records, and/or future clinical trials. PMID- 29196990 TI - Diagnostic Imaging: Ultrasound. AB - Diagnostic ultrasound imaging, particularly that which includes pulsed wave Doppler interrogation, is a safe, real-time modality by which the risk of developing preeclampsia can be refined, and the effects of established disease can be assessed.

PMID- 29196989 TI - Mixed Approach Retrospective Analyses of Suicide and Suicidal Ideation for Brand Compared with Generic Central Nervous System Drugs. AB - INTRODUCTION: Several different types of drugs acting on the central nervous system (CNS) have previously been associated with an increased risk of suicide and suicidal ideation (broadly referred to as suicide). However, a differential association between brand and generic CNS drugs and suicide has not been reported. OBJECTIVES: This study compares suicide adverse event rates for brand versus generic CNS drugs using multiple sources of data. METHODS: Selected examples of CNS drugs (sertraline, gabapentin, zolpidem, and methylphenidate) were evaluated via the US FDA Adverse Event Reporting System (FAERS) for a hypothesis-generating study, and then via administrative claims and electronic health record (EHR) data for a more rigorous retrospective cohort study. Disproportionality analyses with reporting odds ratios and 95% confidence intervals (CIs) were used in the FAERS analyses to quantify the association between each drug and reported suicide. For the cohort studies, Cox proportional hazards models were used, controlling for demographic and clinical characteristics as well as the background risk of suicide in the insured population. RESULTS: The FAERS analyses found significantly lower suicide reporting rates for brands compared with generics for all four studied products (Breslow-Day P < 0.05). In the claims- and EHR-based cohort study, the adjusted hazard ratio (HR) was statistically significant only for sertraline (HR 0.58; 95% CI 0.38-0.88). CONCLUSION: Suicide reporting rates were disproportionately larger for generic than for brand CNS drugs in FAERS and adjusted retrospective cohort analyses remained significant only for sertraline. However, even for sertraline, temporal confounding related to the close proximity of black box warnings and generic availability is possible. Additional analyses in larger data sources with additional drugs are needed. PMID- 29196991 TI - Biomarker Immunoassays in the Diagnosis of Preeclampsia: Calculating the sFlt1/PlGF Ratio Using the Cobas(r)e 411 Analyser. AB - Preeclampsia is a relatively common pregnancy-related condition associated with serious maternal and fetal morbidity and mortality. It is now well established that anti-angiogenic sFlt1 is upregulated in preeclampsia and binds PlGF and VEGF, causing an imbalance in angiogenic factors with subsequent endothelial injury and dysfunction. Measurement of placental growth factor (PlGF) and the sFlt1/PlGF ratio have both been validated in other countries for screening and diagnosis of preeclampsia and the differentiation of preeclampsia from other hypertensive disorders of pregnancy. There are several automated, commercially available immunoassays capable of measuring PlGF and the sFlt1/PlGF ratio for preeclampsia diagnosis. Here we outline the methodology for using the Roche Cobas (r) e 411 immunoassay platform to determine the sFlt1/PlGF ratio. PMID- 29196992 TI - Assessing the Circulating Placental-Specific Anti-angiogenic Protein sFLT-1 e15a in Preeclampsia. AB - Preeclampsia is a common obstetric complication globally responsible for a significant burden of maternal and perinatal morbidity and mortality. The anti angiogenic protein, sFLT-1, plays a central role in its pathophysiology. sFLT-1 is released from a range of tissues into the circulation, where it antagonizes the activity of vascular endothelial growth factor and placental growth factor leading to endothelial dysfunction. The resulting widespread endothelial dysfunction produces the clinical features of preeclampsia including hypertension and proteinuria. Multiple splice variants of sFLT-1 have been identified, with one, known as sFLT-1 e15a, present only in humans and higher-order primates. This sFLT-1 variant is also the main form of sFLT-1 produced by the placenta. Recent work has shown that sFLT-1 e15a is significantly elevated in the placenta and circulation of women with preeclampsia. It is also biologically active, capable of causing endothelial dysfunction and end-organ dysfunction seen in preeclampsia. Indeed, overexpression of sFLT-1 e15a in mice recapitulates the preeclamptic phenotype in pregnancy. No commercial assay currently exists to analyze sFLT-1 e15a protein levels. Here, a new ELISA method to determine circulating sFLT-1 variant levels is described. PMID- 29196993 TI - Role of Activin A in the Pathogenesis of Endothelial Cell Dysfunction in Preeclampsia.

AB - Preeclampsia (PE) is a serious hypertensive disorder that affects up to 8% of all pregnancies annually. An established risk factor for PE is family history, clearly demonstrating an underlying genetic component to the disorder. To date, numerous genetic studies, using both the candidate gene and genome-wide approach, have been undertaken to tease out the genetic basis of PE and understand its origins. Such studies have identified some promising candidate genes such as STOX1 and ACVR2A. Nevertheless, researchers face ongoing challenges of replicating these genetic associations in different populations and performing the functional validation of identified genetic variants to determine their causality in the disorder. This chapter will review the genetic approaches used in the study of PE, discuss their limitations and possible confounders, and describe current strategies. PMID- 29196995 TI - Epigenetics and Preeclampsia: Programming of Future Outcomes. AB - Pregnancy is known to induce rapid, progressive, and substantial changes to the cardiovascular system, ultimately facilitating successful pregnancy outcomes. Women who develop hypertensive disorders during pregnancy are considered to have "failed" the cardiovascular stress test of pregnancy and likely represent a subpopulation with inadequate cardiovascular accommodation. Preeclampsia is a serious complication with a myriad of manifestations in both mother and offspring. This pregnancy syndrome is a polygenic disease and has now been linked to a greater incidence of cardiovascular disease. Moreover, offsprings born to preeclamptic mothers exhibit an elevated risk of cardiovascular disease, stroke, and mental disorders during adulthood. This suggests that preeclampsia not only exposes the mother and the fetus to complications during pregnancy but also programs chronic diseases during adulthood in the offspring. The etiology of preeclampsia remains unknown, with various theories being suggested to explain its origin. It is primarily thought to be associated with poor placentation and entails excessive maternal inflammation and endothelial dysfunction. It is well established now that the maternal immune system and the placenta are involved in a highly choreographed cross talk that underlies adequate spiral artery remodeling required for uteroplacental perfusion and free flow of nutrients to the fetus. Although it is not clear whether immunological alterations occur early during pregnancy, studies have proposed that dysregulated systemic and placental immunity contribute to impaired angiogenesis and the onset of preeclampsia. Recently emerged strong evidence suggests a potential link among epigenetics, microRNAs (miRNAs), and pregnancy complications. This chapter will focus on important aspects of epigenetics, immunological aspects, and cardiovascular and vascular remodeling of preeclampsia. PMID- 29196996 TI - Inflammatory and Immune System Markers. AB - Since preeclampsia was first described by Hippocrates in 400 BC, the theory of its causation has shifted from toxins to a current theory that incorporates both vascular and immunological causation. Poor placentation whether it is genetically predisposed or due to low expression of defective HLA-G on fetal trophoblasts is believed to be the initial insult. Oxidative stress from placental ischemia/hypoxia leads to an overload of trophoblast debris by stimulating apoptosis or necrosis. Partial failure of the maternal immune system to tolerate the paternal alloantigens activates maternal immune cells to secrete cytokines whose pleiotropic functions lead to dysfunction of the maternal vascular and placental endothelium, blood coagulation, and fibrinolytic system. This chapter describes some of the key methodologies (flow cytometry, ELISAs, and multiplex immunoassays) for the identification and quantification of inflammation and immune system markers in the study of preeclampsia pathogenesis, as well as diagnostic and therapeutic development. The methodologies may be utilized for a variety of tissue sources in the study of preeclampsia: maternal peripheral blood, umbilical cord blood, intervillous blood, decidua, chorionic villous, amnion and chorion membranes, and cell culture supernatant. PMID- 29196997 TI - Methods to Enrich Exosomes from Conditioned Media and Biological Fluids. AB - Exosomes are nano-vesicles which can transport a range of molecules including but not limited to proteins and miRNA. This ability of exosomes renders them useful in cellular communication often resulting in biological changes. They have several functions in facilitating normal biological processes such as immune responses and an involvement in pregnancy. However, they have also been linked to pathological conditions including cancer and pregnancy complications such as preeclampsia. An understanding for the role of exosomes in preeclampsia is based on the ability to purify and characterize exosomes. There have been several techniques proposed for the enrichment of exosomes such as ultracentrifugation, density gradient separation, and ultrafiltration although there is no widely accepted optimized technique. Here we describe a workflow for isolating exosomes from cell-conditioned media and biological fluids using a combination of centrifugation, buoyant density, and ultrafiltration approaches.

AB - Ex vivo culture of human placental explants has long allowed placentologists to study the milieu of soluble factors secreted by the human placenta throughout gestation while retaining the correct three-dimensional structure of the placental villi. Here, we detail the placental explant culture method employed in our laboratory to collect extracellular vesicles which are known to be released by the human placenta throughout pregnancy from 6 weeks of gestation. Using this method, at least three different populations of placental extracellular vesicles can be simultaneously collected from each placental sample, allowing for comparative analysis of the cargos and downstream effects of the different types of extracellular vesicles produced by the human placenta. PMID- 29196999 TI - Optimized Specific Isolation of Placenta-Derived Exosomes from Maternal Circulation. AB - Exosomes are small (~100 nm) vesicles that carry a wide range of molecules including proteins, RNAs, and DNA. Exosomes are secreted from a wide range of cells including placental cells. Interestingly, exosomes secreted from placental cells have been identified in maternal circulation as early as in 6 weeks of gestation, and their concentration increases with the gestational age. While there is growing interest in elucidating the role of exosomes during normal and complicated pregnancies (such as preeclampsia), progress in the field has been delayed because of the inability to isolate placental exosomes from maternal circulation. Therefore, here we describe a workflow to isolate placental exosomes from maternal circulation. PMID- 29197000 TI - Proteomics Method to Identification of Protein Profiles in Exosomes. AB - Exosomes are membrane-bound nanovesicles that transport molecular signals (e.g., proteins) between cells and are released from a wide range of cells, including the human placenta. Interestingly, the levels of exosomes present in maternal circulation are higher in preeclamptic pregnancies and their protein content profile change in response to the microenvironment milieu. Through the discovery of candidate biomarkers, mass spectrometry (MS)-based proteomics may provide a better understanding of the pathophysiology underlying pregnancy-associated disorders. With advances in sample preparation techniques, computational methodologies, and bioinformatics, MS-based proteomics have addressed the challenge of identifying and quantifying thousands of proteins and peptides from a variety of complex biological samples. Despite increasing interest in biomarker diagnostics, the complex nature of biological matrices (e.g., plasma) poses a challenge for candidate biomarker discovery. Here we describe a workflow to prepare exosomes for proteomic analysis. PMID- 29197001 TI - Harvesting and Characterization of Syncytial Nuclear Aggregates Following Culture of First Trimester Human Placental Explants. AB - There is currently no effective method to study multinucleated trophoblast debris extruded from the syncytiotrophoblast into the maternal circulation. In Chapter 9 , an in vitro placental explant culture model to generate trophoblast debris was described. Here, we detail the method utilized to isolate individual large multinucleated syncytial nuclear aggregates (SNAs) that are extruded from the syncytiotrophoblast following the culture of first trimester human placental explants. Syncytial nuclear aggregates have been observed in the peripheral maternal circulation as early as 6 weeks' gestation and may play a role in tolerating the maternal immune system during pregnancy. Conversely, aberrant cell death processes in the syncytiotrophoblast due to various maternal factors leading to the extrusion of SNAs that are altered in nature have been implicated in the development of preeclampsia. The methods described herein allow for the isolation and harvest of SNAs without other types of extruded trophoblast debris and can be used to investigate the effect of various maternal factors on the nature of SNAs extruded from the placenta in vitro. PMID- 29197002 TI - Use of GATA3 and TWIST1 Immunofluorescence Staining to Assess In Vitro Syncytial Fusion Index. AB - In human placenta, the multinucleated syncytiotrophoblast (ST) allows all the exchanges between the maternal and fetal circulation and is also the site of placental hormonal functions. Absence or disturbances of ST formation are associated with a defect or pathologies of pregnancy such as preeclampsia (PE) and intrauterine growth retardation (IUGR). All along pregnancy, the ST is regenerated by fusion of underlying mononucleated villous cytotrophoblasts (VCT). The protocol described here provides details on how GATA3 or TWIST1 immunostaining and analysis can be used to easily assess the in vitro differentiation of human placental cytotrophoblast.

PMID- 29197004 TI - Immunohistological Techniques. AB - Preeclampsia is associated with histological alterations in the placenta. These alterations can be described by means of histological techniques. More specifically, immunohistochemistry could be used to detect proteins, and these in turn may be used to identify a specific cell type, to differentiate it from other cell types and to detect the expression of some markers deregulated in preeclampsia.This chapter focuses on the detection of specific cellular and molecular markers that evidence the alterations in the human placenta in preeclampsia. PMID- 29197005 TI - Using a Next-Generation Sequencing Approach to Profile MicroRNAs from Human Origin. AB - Next-generation sequencing is a powerful method to interrogate the nucleotide composition for millions of DNA strands simultaneously. This technology can be utilized to profile microRNAs from multiple origins, such as tissues, cells, and body fluids. Next-generation sequencing is increasingly becoming a common and readily available technique for all laboratories. However, the bottleneck for next-generation sequencing is not within the laboratory but with the bioinformatics and data analysis of next-generation sequencing data. This chapter briefly describes the methods used to prepare samples for next-generation sequencing within the laboratory, before a deeper description of the methods used for data analysis. PMID- 29197006 TI - Isolation and Purification of Villous Cytotrophoblast Cells from Term Human Placenta. AB - The placenta is a key element during pregnancy for the health of the fetus and the mother, which justifies why placental studies are so important. One of the best models for placental studies is the primary cell culture of cytotrophoblast cells from human term placentas. In this chapter, we will detail firstly the isolation of cytotrophoblast cells, with tissue preparation, digestion, Percoll gradient, and cell freezing, and secondly the cell immunopurification and seeding. PMID- 29197007 TI - Analyzing Trophoblast Function Using Cell-Based Assays. AB - Functional cell-based assays are useful for comparing the effect of a treatment, drug, or condition on cells in culture. Cell lines are a commonly used model to replicate a normal biological process or a pathological condition. Trophoblasts within the placenta are required to perform a variety of functions, which include proliferation, differentiation, migration, and invasion for efficient placentation to occur. These functions are impaired in trophoblasts from preeclamptic pregnancies, and therefore functional cell-based assays can be utilized to measure differences and dissect molecular regulatory pathways. PMID- 29197008 TI - Isolation and Characterization of Mesenchymal Stem/Stromal Cells Derived from Human Third Trimester Placental Chorionic Villi and Decidua Basalis. AB - The decidua basalis and placental chorionic villi are critical components of maternal-fetal interface, which plays a critical role in normal placental development. Failure to form a proper maternal-fetal interface is associated with clinically important placental pathologies including preeclampsia and fetal growth restriction. Placental trophoblast cells are well known for their critical roles in establishing the maternal-fetal interface; however accumulating evidence also implicates mesenchymal stem/stromal cells that envelop the maternal and fetal blood vessels as playing an important role in the formation and efficient functioning of the interface. Moreover, recent studies associate abnormal mesenchymal stem/stromal cell function in the development of preeclampsia. Further research is needed to fully understand the role that these cells play in this clinically important placental pathology.The intimate relationship between maternal and fetal tissues at the interface poses significant problems in the enrichment of decidua basalis and chorionic villous mesenchymal stem/stromal cells without significant cross-contamination. The protocols described below for the enrichment and characterization of mesenchymal stem/stromal cells from the maternal-fetal interface produce highly enriched cells that conform to international standards and show minimal cross-contamination. PMID- 29197009 TI - An Electrical Impedance-Based Assay to Examine Functions of Various Placental Cell Types In Vitro. AB - In vitro functional analyses of cells are widely used to investigate the molecular mechanisms involved in preeclampsia. Common cellular functions studied include adhesion, apoptosis, proliferation, migration, and invasion. At present, most researchers will use endpoint experimental assays that only allow the determination of cell function at a single time point, with the need to repeat the experiment for an alternate time point. Here, we describe an electrical impedance-based tool that allows real-time monitoring of cells, which enables the efficient assessment of multiple time points over the duration of a single experiment. PMID- 29197010 TI - In Vitro Induction of Hypoxia/Reoxygenation on Placental Cells: A Suitable Model for Understanding Placental Diseases. AB - Lack of blood flow and aberrant levels of oxygenation in placentas are recurrent in pregnancy diseases, such as preeclampsia. These alterations generate situations of hypoxia and hypoxia/reoxygenation (H/R) and consequent oxidative stress, increased cell death, and inflammation in trophoblasts. The models used to understand the effects of hypoxia and H/R on trophoblasts require a rather big structure. This chapter describes the details of a suitable and reasonable approach with hypoxia chambers to expose human placental trophoblasts to variable conditions of oxygenation. PMID- 29197011 TI - Measurement of Oxidative Stress: Mitochondrial Function Using the Seahorse System. AB - The Seahorse XFp Analyzer is a powerful tool for the assessment of various parameters of cellular respiration. Here we describe the process of the Seahorse Cell Phenotype Test using the Seahorse XFp Analyzer to characterize the metabolic phenotype of live cells. The Seahorse XFp Analyzer can also be coupled with other assays to measure cellular energetics. Given that mitochondrial dysfunction is implicated in preeclampsia, the Seahorse XFp Analyzer will serve as a useful tool for the understanding of pathological metabolism in this disorder. PMID- 29197012 TI - Co-culture of H295R Adrenocortical Carcinoma and BeWo Choriocarcinoma Cells to Study Feto-placental Interactions: Focus on Estrogen Biosynthesis. AB - Estrogens are produced in large amounts during pregnancy, as a result of a tightly regulated cooperation between the maternal and fetal adrenal cortex, which produce androgen precursors, and the placental villous trophoblast, which transforms these precursors into estrogens. These estrogens play an important role in proper placental function, in adaptation of the mother to pregnancy, as well as in adequate fetal development. Disruption of estrogen production is associated with poor pregnancy outcomes and fetal malformation or altered fetal programming. Pregnant women may be exposed to endocrine disruptors from environmental sources or medications, and it is crucial to study the effects of such compounds on feto-placental steroidogenesis. The H295R/BeWo co-culture model offers the opportunity to study these interactions, by making it possible to evaluate the effects of chemical exposures on androgen and estrogen biosynthesis, as well as on various other aspects of feto-placental communication. PMID- 29197013 TI - Placental Lipid Transport. AB - The human placenta is responsible for the adequate supply of nutrients essential for proper embryonic and fetal development such as glucose, amino acids, and lipids. Processes involved in the placental transport of these nutrients are complex and tightly regulated and involve many transporters, receptors, and regulators. In this chapter, we describe the current methods to study the impact of maternal metabolic disorders on key players of human placental transfer of nutrients. PMID- 29197014 TI - EG-VEGF Maintenance Over Early Gestation to Develop a Pregnancy-Induced Hypertensive Animal Model. AB - During the last decade, multiple animal models have been developed to mimic hallmarks of pregnancy-induced hypertension (PIH) diseases, which include gestational hypertension, preeclampsia (PE), or eclampsia. Converging in vitro, ex vivo, and clinical studies from our group strongly suggested the potential involvement of the new angiogenic factor EG-VEGF (endocrine gland-derived-VEGF) in the development of PIH. Here, we described the protocol that served to demonstrate that maintenance of EG-VEGF production over 11.5 days post coitus (dpc) in the gravid mice caused the development of PIH. The developed model exhibited most hallmarks of preeclampsia. PMID- 29197015 TI - Real-Time Blood Pressure Recording Using Radiotelemetry in a Rat Model of Preeclampsia. AB - Radiotelemetry is increasingly being recognized not just as the gold standard but a necessity for validation of gestational hypertension seen in preeclampsia. Here we describe radiotelemetry probe implantation into the descending aorta of Sprague-Dawley rats to allow real-time blood pressure recording over the entire gestational period. This is a valuable tool to be able to track changes in maternal blood pressure throughout gestation and the efficacy of novel therapeutic agents in controlling hypertension.

PMID- 29197017 TI - A Randomized Double-Blinded Placebo-Controlled Intervention Trial of Melatonin for the Prevention of Preeclampsia in Moderate- and High-Risk Women: The MELPOP Trial.

PMID- 29197018 TI - [Rare incidental finding in the hepatoduodenal ligament : Case report and review of the literature]. PMID- 29197019 TI - [Quality indicators for pancreatic surgery : Scientific derivation and clinical relevance]. AB - Quality indicators are by definition indirect measures of quality. The selection for the field of pancreatic surgery was based on the clinical relevance and controllability, scientific evidence and the practicability of data acquisition. In terms of outcome quality, hospital mortality, the composite endpoint MTL30 (mortality-transfer-length of stay), and major complications (Clavien-Dindo classification grades 3b and 4) were chosen as being essential. With respect to structural quality, the presence of interventional radiology with constant availability was considered essential. To evaluate target values two strategies were used: a systematic literature search and evaluation of the current numbers from the German Society for General and Visceral Surgery (DGAV) StuDoQ|Pancreas registry for the years 2014-2016. The results are presented in the following consensus statement. PMID- 29197020 TI - Quality of life in sarcopenia measured with the SarQoL(r): impact of the use of different diagnosis definitions. AB - BACKGROUND: The SarQoL(r) is a recently developed quality of life questionnaire specific to sarcopenia. AIM: To compare the quality of life (QoL) of subjects identified as sarcopenic with that of non-sarcopenic subjects when using six different operational definitions of sarcopenia. METHODS: Participants of the SarcoPhAge study (Belgium) completed the SarQoL(r). Among the six definitions used, two were based on low lean mass alone (Baumgartner, Delmonico), and four required both low muscle mass and decreased performance (Cruz-Jentoft, Studenski, Fielding, Morley). Physical assessments included measurements of muscle mass with dual energy X-ray absorptiometry, muscle strength with a handheld dynamometer and gait speed over a 4-m distance. RESULTS: A total of 387 subjects completed the SarQoL(r). Prevalence of sarcopenia varied widely across the different definitions. Using the SarQoL(r), a lower QoL was found for sarcopenic subjects compared to non-sarcopenic subjects when using the definitions of Cruz-Jentoft (56.3 +/- 13.4 vs 68.0 +/- 15.2, p < 0.001), Studenski (51.1 +/- 14.5 vs 68.2 +/- 14.6, p < 0.001), Fielding (53.8 +/- 12.0 vs 68.3 +/- 15.1, p < 0.001), and Morley (53.3 +/- 12.5 vs 67.1 +/- 15.3, p < 0.001). No QoL difference between sarcopenic and non-sarcopenic subjects was found when using the definitions of Baumgartner or Delmonico, which were only based on the notion of decreased muscle mass. DISCUSSION AND CONCLUSIONS: The SarQoL(r) was able to discriminate sarcopenic from non-sarcopenic subjects with regard to their QoL, regardless of the definition used for diagnosis as long as the definition includes an assessment of both muscle mass and muscle function. Poorer QoL, therefore, seems more related to muscle function than to muscle mass. PMID- 29197021 TI - How to accelerate the upper urinary stone discharge after extracorporeal shockwave lithotripsy (ESWL) for < 15 mm upper urinary stones: a prospective multi-center randomized controlled trial about external physical vibration lithecbole (EPVL). AB - OBJECTIVE: To asset the efficacy and safety of EPVL plus ESWL compared with ESWL alone for the treatment of simple upper urinary stones (< 15 mm). MATERIALS AND METHODS: All patients with upper urinary stones (< 15 mm) were prospectively randomized into two groups. In treatment group, patients were assigned to immediate EPVL after ESWL, while in control group, ESWL alone was offered. All patients were reexamined at 1, 2, and 4 weeks after ESWL. Stone size, stone location, stone-free rate (SFR), and complication rate were compared. RESULTS: 56 males and 20 females in treatment group were compared to 52 male and 25 females in control group (p = 0.404). Median ages were 42.9 +/- 1.5 years in treatment group and 42.7 +/- 1.3 years in control group (p = 0.943). Median stone size was 10.0 +/- 0.4 mm (3-15 mm) in treatment group and 10.4 +/- 0.4 mm (4-15 mm) in control group (p = 0.622). The stone clearance rate in treatment and control group at 1 week after ESWL was 51.3% (39/76) and 45.4% (35/77) (p > 0.05), at 2 weeks was 81.6% (62/76) and 64.9% (50/77) (p < 0.05), and at 4 weeks was 90.8% (69/76) and 75.3% (58/77) (p < 0.05), respectively. CONCLUSIONS: EPVL is a noninvasive, effective, and safe adjunctive treatment which increases and accelerates upper urinary stones discharge after ESWL treatment.

AB - Klippel-Trenaunay-Weber syndrome (KTWS) involves a triad of conditions, including cutaneous hemangiomas, venous varicosities, and osseous and soft-tissue hypertrophy of the affected limb. We describe a rare case of multiple cavernomas in the central nervous system in a patient with KTWS. A-64-year-old man with KTWS and a previous brain hemorrhage presented with sudden onset of gait and vesicorectal disturbance. The magnetic resonance imaging scan showed a cavernoma associated with hemorrhage in his lumbosacral spinal cord. Moreover, numerous cavernomas were identified in his brain. He was treated conservatively with no adverse events. Gait disturbance improved, but vesicorectal disturbance did not improve. PMID- 29197022 TI - Endosymbiont CLS-HI plays a role in reproduction and development of Haemaphysalis longicornis. AB - Coxiella-like endosymbiont (CLS-Hl) is a primary endosymbiont of Haemaphysalis longicornis. CLS-Hl infects tick special tissues and its prevalence is 100% in ovaries and Malpighian tubules. Tetracycline was injected into females, which then fed on rabbits also treated with tetracycline. The densities of CLS-Hl were measured by semi-quantitative PCR. CLS-Hl densities in ovaries and Malpighian tubes of H. longicornis had significant effects on engorged weight, feeding time, number of eggs, oviposition period, and hatching period. These findings suggested that CLS-Hl plays a role in the reproduction and development of H. longicornis. PMID- 29197024 TI - Impact of incomplete ventricular coverage on diagnostic performance of myocardial perfusion imaging. AB - In the context of myocardial perfusion imaging (MPI) with cardiac magnetic resonance (CMR), there is ongoing debate on the merits of using technically complex acquisition methods to achieve whole-heart spatial coverage, rather than conventional 3-slice acquisition. An adequately powered comparative study is difficult to achieve given the requirement for two separate stress CMR studies in each patient. The aim of this work is to draw relevant conclusions from SPECT MPI by comparing whole-heart versus simulated 3-slice coverage in a large existing dataset. SPECT data from 651 patients with suspected coronary artery disease who underwent invasive angiography were analyzed. A computational approach was designed to model 3-slice MPI by retrospective subsampling of whole- heart data. For both whole-heart and 3-slice approaches, the diagnostic performance and the stress total perfusion deficit (TPD) score-a measure of ischemia extent/severity were quantified and compared. Diagnostic accuracy for the 3-slice and whole-heart approaches were similar (area under the curve: 0.843 vs. 0.855, respectively; P = 0.07). The majority (54%) of cases missed by 3-slice imaging had primarily apical ischemia. Whole-heart and 3-slice TPD scores were strongly correlated (R2 = 0.93, P < 0.001) but 3-slice TPD showed a small yet significant bias compared to whole heart TPD (- 1.19%; P < 0.0001) and the 95% limits of agreement were relatively wide (- 6.65% to 4.27%). Incomplete ventricular coverage typically acquired in 3 slice CMR MPI does not significantly affect the diagnostic accuracy. However, 3 slice MPI may fail to detect severe apical ischemia and underestimate the extent/severity of perfusion defects. Our results suggest that caution is required when comparing the ischemic burden between 3-slice and whole-heart datasets, and corroborate the need to establish prognostic thresholds specific to each approach. PMID- 29197025 TI - German cardiac CT registry: indications, procedural data and clinical consequences in 7061 patients undergoing cardiac computed tomography. AB - Cardiac computed tomography permits quantification of coronary calcification as well as detection of coronary artery stenoses after contrast enhancement. Moreover, cardiac CT offers high-resolution morphologic and functional imaging of cardiac structures which is valuable for various structural heart disease interventions and electrophysiology procedures. So far, only limited data exist regarding the spectrum of indications, image acquisition parameters as well as results and clinical consequences of cardiac CT examinations using state-of-the art CT systems in experienced centers. Twelve cardiology centers with profound expertise in cardiovascular imaging participated in the German Cardiac CT Registry. Criteria for participation included adequate experience in cardiac CT as well of the availability of a 64-slice or newer CT system. Between 2009 and 2014, 7061 patients were prospectively enrolled. For all cardiac CT examinations, patient parameters, procedural data, indication and clinical consequences of the examination were documented. Mean patient age was 61 +/- 12 years, 63% were males. The majority (63%) of all cardiac CT examinations were performed in an outpatient setting, 37% were performed during an inpatient stay. 91% were elective and 9% were scheduled in an acute setting. In most examinations (48%), reporting was performed by cardiologists, in 4% by radiologists and in 47% of the cases as a consensus reading. Cardiac CT was limited to native acquisitions for assessment of coronary artery calcification in 9% of patients, only contrast enhanced coronary CT angiography was performed in 16.6% and combined native and contrast-enhanced coronary CT angiography was performed in 57.7% of patients. Non coronary cardiac CT examinations constituted 16.6% of all cases. Coronary artery calcification assessment was performed using prospectively ECG-triggered acquisition in 76.9% of all cases. The median dose length product (DLP) was 42 mGy cm (estimated effective radiation dose of 0.6 mSv). Coronary CT angiography was performed using prospectively ECG-triggered acquisition in 77.3% of all cases. Tube voltage was 120 kV in 67.8% of patients and 100 kV in 30.7% of patients, with a resultant median DLP of 256 mGy cm (estimated effective dose of 3.6 mSv). Clinical consequences of cardiac CT were as follows: in 46.8% of the cases, invasive coronary angiography could be avoided; ischemia testing was recommended in 4.7% of the cases, invasive coronary angiography was recommended in 16.4% of the cases and change in medication in 21.6% of the examinations. Cardiac CT is performed in the majority of patients for non-invasive evaluation of the coronary arteries. CT frequently resulted in medication change, and otherwise planned downstream testing including invasive angiography could be avoided in a high percentage of patients. Radiation exposure in experienced centers is relatively low. PMID- 29197026 TI - An expression atlas of miRNAs in Arabidopsis thaliana. AB - MicroRNAs (miRNAs) are small non-coding RNAs that regulate a variety of biological processes. MiRNA expression often exhibits spatial and temporal specificity. However, genome-wide miRNA expression patterns in different organs during development of Arabidopsis thaliana have not yet been systemically investigated. In this study, we sequenced small RNA libraries generated from 27 different organ/tissue types, which cover the entire life cycle of Arabidopsis. Analysis of the sequencing data revealed that most miRNAs are ubiquitously expressed, whereas a small set of miRNAs display highly specific expression patterns. In addition, different miRNA members within the same family have distinct spatial and temporal expression patterns. Moreover, we found that some miRNAs are produced from different arms of their hairpin precursors at different developmental stages. This work provides new insights into the regulation of miRNA biogenesis and a rich resource for future investigation of miRNA functions in Arabidopsis. PMID- 29197028 TI - Best practices for authenticating cell lines. AB - Experiments using cell cultures are only valid to the extent that the cell culture is a true model system for the biological system being investigated. To assure that a cell line is and remains an appropriate biological model, its identity, purity, ploidy, and phenotype must be maintained. These characteristics comprise and determine the authenticity of a cell line. Routine monitoring of the cell line through microscopic examination of morphology can help to determine authenticity, as can the determination of phenotypic status. Assays designed to confirm cell identity and ploidy and freedom from cross-contaminating cell types may need to be performed at certain times, as such information may not be obtained through morphologic and phenotypic examinations alone. The best practices associated with establishing cell line authenticity are described in this article. PMID- 29197027 TI - Best practices for detecting and mitigating the risk of cell culture contaminants. AB - A variety of biological and chemical contaminants can adversely impact cells in culture, ranging from outright destruction of the culture, mutation, phenotypic changes to relatively minor changes in morphology, or growth rate. There are various approaches to detecting and mitigating the risk of biological or microbial contaminants in cell cultures, and these are discussed in this article. Chemical contaminants typically arise from improper handling or sourcing of cell culture reagents, glassware, or other types of consumables. These and other sources of chemical contaminants of cell cultures are discussed. The occurrence of chemical contamination is mitigated through adherence to best practices in sourcing and handling of such materials and by avoiding the use of volatile solvents within incubators that are used for maintaining cell cultures. PMID- 29197029 TI - Vasculogenic and angiogenic potential of adipose stromal vascular fraction cell populations in vitro. AB - Adipose-derived stromal vascular fraction (SVF) is a heterogeneous cell source that contains endothelial cells, pericytes, smooth muscle cells, stem cells, and other accessory immune and stromal cells. The SVF cell population has been shown to support vasculogenesis in vitro as well vascular maturation in vivo. Matrigel, an extracellular matrix (ECM) mixture has been utilized in vitro to evaluate tube formation of purified endothelial cell systems. We have developed an in vitro system that utilizes freshly isolated SVF and ECM molecules both in pure form (fibrin, laminin, collagen) as well as premixed form (Matrigel) to evaluate endothelial tip cell formation, endothelial stalk elongation, and early stages of branching and inosculation. Freshly isolated SVF rat demonstrate cell aggregation and clustering (presumptive vasculogenesis) on Matrigel ECM within the first 36 h of seeding followed by tip cell formation, stalk cell formation, branching, and inosculation (presumptive angiogenesis) during the subsequent 4 days of culture. Purified ECM molecules (laminin, fibrin, and collagen) promote cell proliferation but do not recapitulate events seen on Matrigel. We have created an in vitro system that provides a functional assay to study the mechanisms of vasculogenesis and angiogenesis in freshly isolated SVF to characterize SVF's blood vessel forming potential prior to clinical implantation. PMID- 29197030 TI - Identification of key genes fluctuated induced by avian leukemia virus (ALV-J) infection in chicken cells. AB - Avian leukemia subgroup J (ALV-J) is one of the most detrimental neoplastic diseases in poultry production. However, the differences between somatic cells and immune cells post-infection remain poorly understood. The aim of our study was to detect the different responses in chicken to infection with ALV-J in different cell lines. In this study, we detected transcriptome expression changes during infection with ALV-J in chicken embryo fibroblast (CEF) and HD11 cell lines. RNA-Seq was used to determine the expression levels of mRNA transcripts from the two cell types after infection with ALV-J at 1, 4, and 7 dpi, and gene ontology analyses were used to cluster differentially expressed genes into pathways. Quantitative real-time PCR confirmed the expression of 336 and 269 differentially expressed genes in CEF and HD11 lines, respectively, involved in innate immunity (OASL, CCL4), adaptive immunity (LYZ, CD72), apoptosis and autophagy (WISP2, COMP), inflammation (JSC, IL8), and tumorgenesis (PCNA, GPX3). The notable signal transduction pathways included the PPARs signaling pathway and ECM-receptor interactions in CEF, and the Toll-like receptor, NOD-like receptor, and RIG-I-like receptor signaling pathways in HD11. To our knowledge, this is the first study to use high-throughput sequencing methods to investigate viral infection in different cell types. The results of the present study form a foundation for developing potential biological markers for viral infection. PMID- 29197032 TI - miR-221 modulates skeletal muscle satellite cells proliferation and differentiation. AB - MicroRNAs (miRNAs) are a class of small non-coding RNA molecules, which play important roles in animals by targeting mRNA transcripts for translational repression. Many recent studies have shown that miRNAs are involved in the control of muscle development. In this study, the expression levels of miR-221 in different tissues and during rabbit skeletal muscle satellite cells (SMSCs) differentiation were detected. Gene ontology term enrichment was used to predict the potential biological roles of miR-221. A synthetic miR-221 mimic and a miR 221 inhibitor were used to investigate the functions of miR-221 during SMSCs proliferation and differentiation to further verify the functions of miR-221 in muscle development. In this report, we compared the expression levels of miR-221 in different tissues. The expression levels of miR-221 were upregulated after the induction of differentiation, and then were gradually downregulated during SMSCs differentiation. Overexpression of miR-221 promoted SMSCs proliferation, whereas inhibiting expression restrained proliferation in the EdU and CCK-8 assays. In addition, overexpression of miR-221 led to a decline in the expression levels of the differentiation marker genes MyoG and MHC. miR-221 overexpression suppressed SMSCs myotube formation. On the contrary, inhibition of miR-221 promoted myotube formation. Our data showed that miR-221 increased SMSCs proliferation and decreased differentiation. PMID- 29197031 TI - Preclinical evaluation of the Aurora kinase inhibitors AMG 900, AZD1152-HQPA, and MK-5108 on SW-872 and 93T449 human liposarcoma cells. AB - Liposarcoma is a malignant soft tissue tumor that originates from adipose tissue and is one of the most frequently diagnosed soft tissue sarcomas in humans. There is great interest in identifying novel chemotherapeutic options for treating liposarcoma based upon molecular alterations in the cancer cells. The Aurora kinases have been identified as promising chemotherapeutic targets based on their altered expression in many human cancers and cellular roles in mitosis and cytokinesis. In this study, we investigated the effects of an Aurora kinase A inhibitor (MK-5108), an Aurora kinase B inhibitor (AZD1152-HQPA), and a pan Aurora kinase inhibitor (AMG 900) on undifferentiated SW-872 and well differentiated 93T449 human liposarcoma cells. Treatment of the SW-872 and 93T449 cells with MK-5108 (0-1000 nM), AZD1152-HQPA (0-1000 nM), and AMG 900 (0-1000 nM) for 72 h resulted in a dose-dependent decrease in the total viable cell number. Based upon the EC50 values, the potency of the three Aurora kinase inhibitors in the SW-872 cells was as follows: AMG 900 (EC50 = 3.7 nM) > AZD1152-HQPA (EC50 = 43.4 nM) > MK-5108 (EC50 = 309.0 nM), while the potency in the 93T449 cells was as follows: AMG 900 (EC50 = 6.5 nM) > AZD1152-HQPA (EC50 = 74.5 nM) > MK-5108 (EC50 = 283.6 nM). The percentage of polyploidy after 72 h of drug treatment (0 1000 nM) was determined by propidium iodide staining and flow cytometric analysis. AMG 900 caused a significant increase in polyploidy starting at 25 nM in the SW-872 and 93T449 cells, and AZD1152-HQPA caused a significant increase starting at 100 nM in the SW-872 cells and 250 nM in the 93T449 cells. The Aurora kinase A inhibitor MK-5108 did not significantly increase the percentage of polyploid cells at any of the doses tested in either cell line. The expression of Aurora kinase A and B was evaluated in the SW-872 cells versus differentiated adipocytes and human mesenchymal stem cells by real-time RT-PCR and Western blot analysis. Aurora kinase A and B mRNA expression was significantly increased in the SW-872 cells versus the differentiated adipocytes and human mesenchymal stem cells. Western blot analysis revealed a ~ 48 kDa immunoreactive band for Aurora kinase A that was not present in the differentiated adipocytes or the human mesenchymal stem cells. A ~ 39 kDa immunoreactive band for Aurora kinase B was detected in the SW-872 cells, differentiated adipocytes, and human mesenchymal stem cells. A smaller immunoreactive band for Aurora kinase B was detected in the SW-872 cells but not in the differentiated adipocytes and human mesenchymal stem cells, and this may reflect the expression of a truncated splice variant of Aurora kinase B that has been associated with poor patient prognosis. The 93T449 cells demonstrated decreased expression of Aurora kinase A and B mRNA and protein compared to the SW-872 cells, and also expressed the truncated form of Aurora kinase B. The results of these in vitro studies indicate that Aurora kinase inhibitors should be further investigated as possible chemotherapeutic agents for human liposarcoma. PMID- 29197033 TI - Establishment and proteomic characterization of patient-derived clear cell sarcoma xenografts and cell lines. AB - Clear cell sarcoma (CCS) is an aggressive mesenchymal malignancy characterized by the unique chimeric EWS-ATF1 fusion gene. Patient-derived cancer models are essential tools for the understanding of tumorigenesis and the development of anti-cancer drugs; however, only a limited number of CCS cell lines exist. The objective of this study was to establish patient-derived CCS models. We established patient-derived CCS models from a 43-yr-old female patient. We prepared the patient-derived xenografts (PDXs) from tumor tissues obtained through biopsy or surgery and isolated stable cell lines from PDXs and the original tumor tissue. The presence of gene fusions was examined by RT-PCR, and Sanger sequencing. The established cell lines were characterized by short tandem repeat, viability, colony and spheroid formation, and invasion analyses. Differences in gene enrichment between the primary tumor and cell lines were examined by mass spectrometry and KEGG pathway analysis. The cell lines were maintained for more than 80 passages, and had tumorigenic characteristics such as colony and spheroid formation and invasion. Mass spectrometric proteome analysis demonstrated that the cell lines were enriched for similar but distinct molecular pathways, compared to those in the xenografts and original tumor tissue. Next, tyrosine kinase inhibitors were screened for their suppressive effects on viability. We found that ponatinib, vandetanib, and doxorubicin suppressed the growth of cell lines, and had equivalent IC50 values. Further in-depth investigation and understanding of drug-sensitivity mechanisms will be important for the clinical applications of our cell lines. PMID- 29197035 TI - The Association Between Apartment Layout and Depressive Symptomology among Hispanic/Latino Residents in Low-Income Housing: the AHOME Study. AB - In this study of low-income Hispanic/Latino adults living in 291 individual apartments in the Bronx, New York, the apartment layout was significantly associated with the odds of depressive symptomology. Women living in apartments in which the most central rooms were the living, dining, or kitchen (i.e., rooms commonly used for communal activities) were less likely to have depressive symptomology (OR = 0.44, 95% CI = 0.22-0.86) than women in apartments where the central rooms were lobbies or corridors, adjusting for demographics, health conditions, and housing and neighborhood characteristics. No statistically significant association was observed in men. We present the logic underlying the use of layout variables in this study and discuss the implications it may have for understanding the role of the home environment on psychological distress among inhabitants. The results of this study show how space syntax analysis can be used to better understanding disparities in the risk of depression and offer an additional opportunity for public health stakeholders to identify those most at risk for depression.

AB - The DSIR-HA-1179 coleopteran cell line has been identified as a susceptible and permissive host for the in vitro replication of the Oryctes nudivirus, which can be used as a biopesticide against the coconut rhinoceros beetle, pest of palms. The major challenge to in vitro large-scale Oryctes nudivirus production is ensuring process economy. This rests, among other requisites, on the use of low cost culture media tailored to the nutritional and metabolic needs of the cell line, both in uninfected and infected cultures. The aim of the present study was to characterize the nutritional demands and the metabolic characteristics of the DSIR-HA-1179 cell line during growth and subsequent infection with Oryctes nudivirus in the TC-100 culture medium. Serum-supplementation of the culture medium was found to be critical for cell growth, and addition of 10% fetal bovine serum v/v led to a maximum viable cell density (16.8 * 105 cells ml-1) with a population doubling time of 4.2 d. Nutritional and metabolic characterization of the cell line revealed a trend of glucose and glutamine consumption but minimal uptake of other amino acids, negligible production of lactate and ammonia, and the accumulation of alanine, both before and after infection. The monitoring of virus production kinetics showed that the TC-100 culture medium was nutritionally sufficient to give a peak yield of 7.38 * 107 TCID50 ml-1 of OrNV at the 6th day post-infection in attached cultures of DSIR-HA-1179 cells in 25 cm2 T-flasks. Knowledge of the cell line's nutritional demands and virus production kinetics will aid in the formulation of a low-cost culture medium and better process design for large-scale OrNV production in future.

AB - As genetics and genomics become part of mainstream medicine, these advances have the potential to either reduce or exacerbate health disparities. Relatively, little research has explored the quality of genetic counseling communication experienced by limited English proficiency patients, especially Chinese Americans. We observed and audio recorded genetic counseling appointments (n = 40) of low-income, limited English-proficient Chinese patients (n = 25) and conducted post-visit interviews (n = 17) using stimulated recall to examine patient understanding of the communication. Standard techniques based in grounded theory, including iterative data review and multiple coders, were used to analyze observation fieldnotes and interview transcripts and to identify these themes: (1) strong beliefs in environmental causes of cancer and skepticism about genetic causes, (2) willingness to undergo genetic testing despite skepticism of hereditary cause of cancer, (3) misunderstanding of key information needed to make informed decisions about testing and screening/prevention options, (4) variable quality of medical interpretation, and (5) selective family communication about cancer and genetic counseling and testing. Together, these themes describe substantial gaps in communication and identify the need for genetic counseling techniques and skills that enable counselors to communicate more effectively across language, literacy, and culture. Understanding the mechanisms of inheritance and the implications of genetic test results can be challenging for anyone, and it is exceptionally daunting for those who have limited English proficiency and/or low literacy. For Chinese immigrant patients to reap the full benefits of genetic counseling and testing, effective communication is essential. Research on interventions to improve communication is needed to ensure that disparities do not widen as genomic medicine reaches a more diverse population. PMID- 29197037 TI - Respiratory response of grass carp Ctenopharyngodon idellus to dissolved oxygen changes at three acclimation temperatures. AB - Respiratory parameters of grass carp were studied during dissolved oxygen (DO) changes from normal DO to hypoxia, then return to normal DO at 15, 25, and 30 degrees C acclimation, respectively. The results showed that with increases of acclimation temperature at normoxia the respiratory frequency (fR), oxygen consumption rate (VO2), respiratory stroke volume (VS.R), gill ventilation (VG), and VG/VO2 of grass carp increased significantly, but the oxygen extraction efficiency (EO2) of fish decreased significantly (P < 0.05). With declines of DO levels, the fR, VS.R, VG, and VG/VO2 of fish increased significantly at different acclimation temperatures (P < 0.05). A slight increase was found in VO2, and the EO2 of fish remained almost constant above DO levels of 3.09, 2.91, and 2.54 mg l 1 at 15, 25, and 30 degrees C, while the VO2 and EO2 began to decrease significantly with further reductions in DO levels (P < 0.05). After 0.5 h of recovery to normoxia from hypoxia at three acclimation, the fR, VS.R, VG, and VG/VO2 of the fish decreased sharply; meanwhile, the VO2 and EO2 increased sharply (P < 0.05). The respiratory parameters of fish gradually approached initial values with prolonged recovery time to normoxia, and reached their initial values in 2.5 h at 25 and 30 degrees C acclimation. The critical oxygen concentrations (Cc) of fish for VO2 were 2.42 mg l-1 at 15 degrees C, 2.02 mg l 1 at 25 degrees C, and 1.84 mg l-1 at 30 degrees C, respectively. The results suggest that grass carp are highly adapted to varied DO and short-term hypoxia environments.

PMID- 29197038 TI - Barbed versus traditional suture for enterotomy closure after laparoscopic right colectomy with intracorporeal mechanical anastomosis: a case-control study. AB - Our aim was to establish the safety and efficacy of barbed suture for enterotomy closure after laparoscopic right colectomy with intracorporeal anastomosis. This study included 47 patients who underwent laparoscopic right hemicolectomy with intracorporeal mechanical anastomosis and barbed suture enterotomy closure (barbed suture closure-BSC) for adenocarcinoma (with the exception of T4 lesions and metastasis), compared with 47 matched patients who underwent laparoscopic right hemicolectomy with intracorporeal mechanical anastomosis and conventional suture enterotomy closure (conventional suture closure-CSC) during the same period. Controls were matched for stage, age, and gender via a statistically generated selection of all laparoscopic right hemicolectomies performed from January 2009 until December 2015. There was no difference between the two groups in terms of age, sex, BMI, ASA, co-morbidity, previous abdominal surgery, cancer site and cancer staging. In terms of operating time (median 120 min for BSC and 127.5 min for CSC), histopathological results, surgical site complications (2.1% for BSC and 8.5% for CSC), hospitalization (median 6 days for BSC and 5 days for CSC), readmission rate (0%), there were no differences between the groups (p > 0.05). No significant differences were noted between the two groups in terms of the postoperative course. Our results support that the use of knotless barbed sutures for enterotomy closure after laparoscopic right colectomy with intracorporeal mechanical anastomosis is safe and reproducible. PMID- 29197040 TI - Phenotypic plasticity and climate change: can polar bears respond to longer Arctic summers with an adaptive fast? AB - Plasticity in the physiological and behavioural responses of animals to prolonged food shortages may determine the persistence of species under climate warming. This is particularly applicable for species that can "adaptively fast" by conserving protein to protect organ function while catabolizing endogenous tissues. Some Ursids, including polar bears (Ursus maritimus), adaptively fast during winter hibernation-and it has been suggested that polar bears also employ this strategy during summer. We captured 57 adult female polar bears in the Southern Beaufort Sea (SBS) during summer 2008 and 2009 and measured blood variables that indicate feeding, regular fasting, and adaptive fasting. We also assessed tissue delta13C and delta15N to infer diet, and body condition via mass and length. We found that bears on shore maintained lipid and protein stores by scavenging on bowhead whale (Balaena mysticetus) carcasses from human harvest, while those that followed the retreating sea ice beyond the continental shelf were food deprived. They had low ratios of blood urea to creatinine (U:C), normally associated with adaptive fasting. However, they also exhibited low albumin and glucose (indicative of protein loss) and elevated alanine aminotransferase and ghrelin (which fall during adaptive fasting). Thus, the ~ 70% of the SBS subpopulation that spends summer on the ice experiences more of a regular, rather than adaptive, fast. This fast will lengthen as summer ice declines. The resulting protein loss prior to winter could be a mechanism driving the reported correlation between summer ice and polar bear reproduction and survival in the SBS. PMID- 29197041 TI - Giving predators a wide berth: quantifying behavioral predator shadows in colonizing aquatic beetles. AB - The perceived quality of habitat patches in complex landscapes is highly context dependent. Characteristics of neighboring patches in such complex landscapes can influence perceived habitat quality, altering colonization dynamics and community structure. Spatial contagion of predation risk across patches has been observed over smaller spatial scales in aquatic systems. Naturally colonizing aquatic beetles were used to examine the spatial dynamics of risk contagion by quantifying the size of predator shadows around fish patches across spatial scales potentially involving numerous patches in natural landscapes. These consisted of fish free, replicate experimental mesocosm arrays radiating from larger central mesocosms containing fish, and allowed examination of the effect of distance to fish on beetle abundance, rarified species richness, and variation in species responses. Overall, beetles avoided pools closer to fish, but species varied in colonization pattern, resulting in species-specific predator shadows and potential behavioral species sorting. The spatial and phylogenetic extent of contagion and other context-dependent effects has implications for the role of complex behavior in the dynamics of communities and metacommunities.

AB - BACKGROUND: The accuracy of sentinel lymph node biopsy (SLNB) after neoadjuvant therapy (NAT) has been improved with the placement of a clip in the positive node prior to treatment. Several methods have been described for clipped node excision during SLNB after NAT. We assessed the feasibility of intraoperative ultrasound (IOUS)-guided excision of the clipped node during SLNB and investigated whether the accuracy of SLNB is improved. METHODS: After approval by the Institutional Ethics Committee, all breast cancer patients undergoing NAT had an US-visible clip placed in the positive node. The ILINA trial consisted of IOUS-guided excision of the clipped node along with SLNB and axillary lymph node dissection (ALND). RESULTS: Forty-six patients had a clip placed in the positive node. In two (4.3%) cases, the clip could not be seen prior to surgery and the patient underwent ALND; however, the clipped node was successfully removed by IOUS-guided excision in 44 patients. Thirty-five patients (79.5%) underwent SLNB along with IOUS-guided excision of the clipped node and ALND, and were subsequently included in the ILINA trial. Nine patients were not included (five patients with SLNB only and four patients with ALND without SLNB). SLNB matched the clipped node in 27 (77%) patients. The false negative rate for the ILINA protocol was 4.1% (95% confidence interval 0.1-21.1%). CONCLUSIONS: IOUS-guided excision of the axillary clipped node after NAT was feasible, safe, and successful in 100% of cases. The ILINA trial is accurate in predicting axillary nodal status after NAT. PMID- 29197045 TI - Shift Towards Older Bariatric Patients. PMID- 29197046 TI - Evaluation of Nutritional Status Post Laparoscopic Sleeve Gastrectomy-5-Year Outcomes. AB - INTRODUCTION: Obesity is considered a public health problem and has led to advancements in bariatric surgery. Laparoscopic sleeve gastrectomy (LSG) had become the most performed procedure worldwide; however, its consequences on nutritional status in the short and long term are of concern. METHODS: A retrospective analysis of medical records and bariatric database of patients who underwent LSG from October 2008-September 2015 at Al-Amiri Hospital, Kuwait, was performed. Data regarding nutritional status along with demographic data were collected over a 5-year follow-up period. RESULTS: One thousand seven hundred ninety-three patients comprising of 74% females and 26% males were included. The greatest % total body weight loss (%TBWL) was at 18 months post-LSG (33%), corresponding to a % excess weight loss (%EWL) of 73.8%. With regard to nutritional status, vitamin B1 showed a significant drop at 3-5 years post-op in comparison to pre-op value, but stayed within the normal range throughout the study. Red blood cells count, hemoglobin, and hematocrit also showed a significant drop starting from 6 months post-op until the fifth year of follow up. On the other hand, vitamins B6 and B12 showed a significant increase at 6 months post-op and decreased afterwards, but did not reach pre-op values. Vitamin D also showed a significant increase throughout the study period from deficient value at the pre-op time, but remained insufficient. Albumin, transferrin, folate, ferritin, iron, and vitamin B2 showed no significant changes at 5 years post-LSG compared to pre-op values. CONCLUSION: Little is known about the nutritional status and optimal nutritional care plan post-LSG, especially in the longer term. Nutritional deficiencies were prevalent prior and post-LSG. Some of the nutritional parameters improved and even reached the abnormal high level post LSG. These observations highlight the importance of pre- and post-operative nutritional assessment and tailored supplementation to ensure optimal nutritional status.

PMID- 29197048 TI - Contraception, Menstruation, and Sexuality after Bariatric Surgery: a Prospective Cohort Study. AB - BACKGROUND: Women with a history of bariatric surgery are recommended to avoid pregnancy at least 12 months after surgery. Evidence on the impact of bariatric surgery on contraception, menstrual cycle, and sexuality in the first year postoperative is therefore indispensable. OBJECTIVES: The objective of this paper is to prospectively study changes in contraception, menstrual cycle and sexuality in women of reproductive age following bariatric surgery. SETTING: The study was conducted in two secondary medical centers and a tertiary academic medical center. METHODS: Women attending for bariatric surgery or who recently underwent bariatric surgery completed online questionnaires about contraception, menstrual cycle, and sexual behavior before surgery and 6 and 12 months after surgery. RESULTS: The study included data from 71 women, including 70 and 47 women at 6 and 12 months after bariatric surgery, respectively. Preoperatively, 43.6% (n = 31/71) used a short-acting hormonal contraceptive, the usage of which decreased significantly to, respectively, 32.8% (n = 23/70; p = .031) and 27.7% (n = 13/47; p = .022) 6 and 12 months post-surgery. Usage of long-acting contraceptive methods increased from 26.7% (n = 19/71) preoperatively to 38.6% (n = 27/70; p = .021) and 42.6% (n = 20/47; p = .004) at 6 and 12 months. Combined oral contraceptives (COC) remained used (39.4% preoperatively, 27.1 and 14.9% at 6 and 12 months postoperatively). Menstrual cycle (frequency, pattern, duration of the cycle, and the menstruation itself) and sexual behavior (intimate relationship, frequency of intercourse, and satisfaction) did not differ significantly before and after surgery. CONCLUSIONS: Women undergoing bariatric surgery appear to switch their type of contraceptive from oral, short-acting hormonal contraceptives to non-oral, long-acting contraceptives. No changes in menstrual cycle and sexual behavior were shown. PMID- 29197050 TI - The common rate control account of prediction motion. AB - In prediction-motion (PM) tasks, people judge the current position of an occluded moving object. People can also judge the current number on an occluded digital counter or the current colour of an occluded colour-change display. These abilities imply that we can run mental simulations at a chosen speed, even without feedback from the senses. There is increasing evidence that the brain has a common rate control module for pacing all such dynamic mental simulations. The common rate control account of PM has more explanatory power than alternative accounts which emphasise the role of mental imagery or the oculomotor system. Finally, neuroimaging work suggests that the common rate controller is a part of a core timing network that incorporates basal ganglia circuitry. PMID- 29197051 TI - Environmental sound priming: Does negation modify N400 cross-modal priming effects? AB - Human information processing is incredibly fast and flexible. In order to survive, the human brain has to integrate information from various sources and to derive a coherent interpretation, ideally leading to adequate behavior. In experimental setups, such integration phenomena are often investigated in terms of cross-modal association effects. Interestingly, to date, most of these cross modal association effects using linguistic stimuli have shown that single words can influence the processing of non-linguistic stimuli, and vice versa. In the present study, we were particularly interested in how far linguistic input beyond single words influences the processing of non-linguistic stimuli; in our case, environmental sounds. Participants read sentences either in an affirmative or negated version: for example: "The dog does (not) bark". Subsequently, participants listened to a sound either matching or mismatching the affirmative version of the sentence ('woof' vs. 'meow', respectively). In line with previous studies, we found a clear N400-like effect during sound perception following affirmative sentences. Interestingly, this effect was identically present following negated sentences, and the negation operator did not modulate the cross modal association effect observed between the content words of the sentence and the sound. In summary, these results suggest that negation is not incorporated during information processing in a manner that word-sound association effects would be influenced.

AB - Discharges of huge quantities of leather solid wastes by leather industries and the increased use of synthetic packaging films have raised serious concerns on account of their environmental impacts. The paper focuses on the development and characterization of potential environmentally friendly composite films using collagen hydrolysate (CH) extracted from leather solid wastes and chitosan (C) to assess the feasibility of producing polymeric materials suitable for applications in packaging and wrapping purposes. Solid collagen-based protein hydrolysate was extracted from chromium-tanned leather wastes and analyzed to determine its chemical properties. With the goal of improving the physico-chemical performance of CH, three types of composite films (CH75/C25, CH50/C50, CH25/C75) were prepared with increasing concentrations of C, and some of their physical and functional properties were characterized. The results indicated that the addition of C caused increase (p < 0.05) in the thickness, tensile strength (TS), elasticity modulus (EM), and water vapor permeability (WVP), leading to stronger films as compared with CH film, but significantly (p < 0.05) decreased the elongation at break (EAB) and solubility of films (p < 0.05). The light barrier measurements present low values of transparency at 600 nm of the CH/C films, indicating that the films are very transparent and they have excellent barrier properties against UV light. The structural properties investigated by FTIR and DSC showed total miscibility between both polymers. Scanning electron micrographs revealed that CH/C composite films showed a compact homogeneous structure. These results demonstrate the potential application of CH/C composite films in packaging industry. PMID- 29197054 TI - Joint toxicity of six common heavy metals to Chlorella pyrenoidosa. AB - Six common heavy metals (Ni, Fe, Zn, Pb, Cd, and Cr) in the water environment were selected to present five groups of binary mixture systems (Ni-Fe, Ni-Zn, Ni Pb, Ni-Cd, and Ni-Cr) through a direct equipartition ray design. Microplate toxicity analysis based on Chlorella pyrenoidosa measured the 96-h joint toxicities of the binary mixtures. Toxicity interaction of the binary mixture was analyzed by comparing the observed toxicity data with the reference model (concentration addition). The results indicated that Ni-Fe, Ni-Pb, and Ni-Cr mixtures showed additive effects at concentration tested. It was indicated that Ni-Zn and Ni-Cd mixtures presented additive effects at low concentrations whereas synergistic effects were seen at high concentrations. PMID- 29197055 TI - Synthesis of Co3O4-Bi2O3 using microwave-assisted method as the peroxymonosulfate activator for elimination of bisphenol A. AB - In this work, Co3O4-Bi2O3 was successfully synthesized using a microwave-assisted method [Co3O4-Bi2O3(MW)] and employed as a peroxymonosulfate (PMS) activator for bisphenol A removal. A reference catalyst was prepared using the same preparation conditions but different heating mode and labeled as Co3O4-Bi2O3(CH). The series of Co3O4-Bi2O3 was characterized using XRD, SEM, and N2 adsorption to detect their crystallinity, morphology, and surface area, among others. Results indicated that both microwave and calcination significantly affected the characteristic and catalytic activity of the catalyst. Moreover, the microwave irradiated catalyst calcined at 300 degrees C showed higher catalytic activity and mineralization percentage for BPA degradation than the conventionally heated catalyst calcined at the same temperature. Microwave temperature and microwave time of the proposed microwave-assisted method were also investigated. Compared with other catalysts, the present catalyst showed considerably superior preparation time and degradation efficiency. This study broadens a new horizon for advanced oxidation process using a PMS activator. PMID- 29197056 TI - Current state of yusho and prospects for therapeutic strategies. AB - The mass food poisoning incident yusho occurred in Japan in 1968. It was caused by the ingestion of rice bran oil contaminated with polychlorinated biphenyls and various dioxins and dioxin-like compounds including polychlorinated dibenzo-p dioxins and polychlorinated dibenzofurans (PCDFs). Notably, PCDFs were found to contribute to approximately 65% of the total toxicity equivalent in the blood of yusho patients. Lipophilic dioxins are retained in the body for a longer period than previously estimated. Victims suffered from characteristic skin manifestations associated with non-specific systemic symptoms, neurological symptoms, and respiratory symptoms. The severe symptoms seen in the initial phase subsequently faded, but recently, improvements have scarcely been observed. The Yusho Group has been researching treatments for this condition. Several clinical trials with chelating agents or dietary fibers aimed at accelerating the excretion of compounds. While some treatments increased dioxin excretion, none provided satisfactory symptom relief. Concurrently, various phytochemicals and herbal extracts have been found to possess biological activities that suppress dioxin-induced toxicity via aryl hydrocarbon receptor or activate the antioxidant nuclear factor-erythroid 2-related factor-2 (NRF2) signal pathway, making them promising therapeutic candidates. Here, we summarize the current status of yusho and findings of clinical trials for yusho patients and discuss the treatment prospects. PMID- 29197057 TI - Extracellular polymeric substances with metal adsorption capacity produced by Pseudoalteromonas sp. MER144 from Antarctic seawater. AB - The EPS-producing Pseudoalteromonas sp. MER144 was selected among 606 isolates from Antarctic seawater due to its evident slimy appearance on agar plates. The production of EPSs was enhanced by a step-by-step approach varying the carbon source, substrate and NaCl concentrations, temperature, and pH. Optimal conditions for the EPS production resulted at temperature of 4 degrees C and pH 7, with addition of 2% sucrose (w/v) and 3% NaCl (w/v). EPSs produced under optimal conditions were chemically characterized, resulting in a moderate carbohydrate content (35%), uronic acids (14%), and proteins (12%). Monosaccharide composition was estimated to be Glu:Man:GluN:Ara:GluA:GalA:Gal (1:0.36:0.26:0.06:0.06:0.05:0.03), while the estimated molecular weight was about 250 kDa. The addition of sucrose in the culture medium, by stimulating the EPS production, allowed MER144 to tolerate higher concentrations of mercury and cadmium. This finding was probably dependent on the presence of uronic acids and sulfate groups, which can bind cations, in the extracted EPSs. Monitoring EPS production under optimal conditions at different concentrations of mercury and cadmium revealed that EPS amounts increased at increasing heavy metal concentrations, indicating an adaptation to the stress conditions tested. PMID- 29197058 TI - Thiamethoxam induced hepatotoxicity and pro-carcinogenicity in rabbits via motivation of oxidative stress, inflammation, and anti-apoptotic pathway. AB - Thiamethoxam (TMX) is a non-mutagenic neonicotinoid insecticide that is widely used to combat different types of insects. The hepatotoxicity and carcinogenicity of TMX have been approved previously in mice but not in rats. However, the TMX induced hepatotoxic and pro-carcinogenic effects on rabbits remain unclear. The present study elucidated the roles of oxidative stress, pro-inflammatory cytokines, and apoptosis-related genes in the hepatotoxic and carcinogenic effects of TMX on rabbits. Sixteen male rabbits were equally divided into two groups; eight rabbits orally treated with TMX at a dose of 250 mg/kg b.w for 90 successive days. Hepatotoxic effects of TMX were evidenced by attenuation of liver enzyme activities, elevation of bilirubin levels, and alterations in the hepatic architecture, including hepatocyte death by necrosis and apoptosis, lymphocyte infiltration and fibrosis. TMX induced oxidative stress, as evidenced by the significant increases in malondialdehyde levels and antioxidant enzyme (glutathione transferase and catalase) activities along with a decrease in glutathione levels. TMX also up-regulated the mRNA levels of interleukin-6 (1.6 fold) and B cell lymphoma-2 (1.8-fold) and down-regulated the mRNA level of the tumor necrosis factor-alpha (0.8-fold), indicating its effects on cell survival and proliferation through the inhibition of apoptosis. Interestingly, the elevated level of carcinoembryonic antigen and the appearance of ground glass like hepatocytes suggested that TMX exerted a pro-carcinogenic effect. In conclusion, TMX exerts potentially hepatotoxic and pro-carcinogenic effects on rabbits by modulating oxidative/antioxidative status and pro-inflammatory cytokine production, inhibiting apoptosis and activating cell survival pathways. PMID- 29197059 TI - Numerical investigation of the efficiency of emission reduction and heat extraction in a sedimentary geothermal reservoir: a case study of the Daming geothermal field in China. AB - The utilization of geothermal energy is clean and has great potential worldwide, and it is important to utilize geothermal energy in a sustainable manner. Mathematical modeling studies of geothermal reservoirs are important as they evaluate and quantify the complex multi-physical effects in geothermal reservoirs. However, previous modeling efforts lack the study focusing on the emission reduction efficiency and the deformation at geothermal wellbores caused by geothermal water extraction/circulation. Emission efficiency is rather relevant in geothermal projects introduced in areas characterized by elevated air pollution where the utilization of geothermal energy is as an alternative to burning fossil fuels. Deformation at geothermal wellbores is also relevant as significant deformation caused by water extraction can lead to geothermal wellbore instability and can consequently decrease the effectiveness of the heat extraction process in geothermal wells. In this study, the efficiency of emission reduction and heat extraction in a sedimentary geothermal reservoir in Daming County, China, are numerically investigated based on a coupled multi-physical model. Relationships between the efficiency of emission reduction and heat extraction, deformation at geothermal well locations, and geothermal field parameters including well spacing, heat production rate, re-injection temperature, rock stiffness, and geothermal well placement patterns are analyzed. Results show that, although large heat production rates and low re-injection temperatures can lead to decreased heat production in the last 8 years of heat extraction, they still improve the overall heat production capacity and emission reduction capacity. Also, the emission reduction capacity is positively correlated with the heat production capacity. Deformation at geothermal wellbore locations is alleviated by smaller well spacing, lower heat production rates, and smaller numbers of injectors in the well pattern, and by placing wells at locations with higher rock stiffness. Compared with the reference case with coal burning for heating purposes, the yearly emission reduction capacity can reach 1 * 107 kg by switching to the direct utilization of geothermal energy in Daming field. PMID- 29197060 TI - Repellency potential of essential oils against housefly, Musca domestica L. AB - In present study, the essential oils such as Mentha piperita (mentha oil, M.O), Cymbopogan citratus (lemongrass oil, LG.O), Citrus sinensis (orange oil, O.O), and Eucalyptus globulus (eucalyptus oil, E.O) were evaluated for repellency against housefly (Musca domestica) in a specially designed chamber. Further, to study any synergistic effect, essential oil combinations, i.e., M.O + LG.O, M.O + O.O, and M.O + E.O, were screened at 50:50 and 70:30 ratios. The results showed superior repellency of mentha and mentha + lemongrass (70:30) with RC95 value of 0.009 MUl/cm3. The other oils and combinations showed higher values of RC95 (0.010-0.041 MUl/cm3). The order of repellency was observed to be mentha = mentha + lemongrass (70:30) > mentha + lemongrass (50:50) = lemongrass = mentha + orange (50:50) = mentha + orange (70:30) > mentha + eucalyptus (70:30) > orange > mentha + eucalyptus (50:50) > eucalyptus. Chemical composition of selected essential oils indicated various monoterpenes as active components for efficient repellency. The essential oil of mentha marked the presence of menthol (38%) and menthone (27%) in major fractions, whereas citral (49%) was found dominating in lemongrass oil. Eucalyptus and orange oils showed the presence of 1,8-cineole (85%), and limonene (87%), respectively, as major components of oils. Further, monoterpenes (menthol and limonene) were also evaluated for repellency against housefly. The data showed 90 +/- 5 and 60 +/- 5% repellency from menthol and limonene, respectively, after 1 h, indicating the vital role of monoterpenes in overall efficacy of essential oil. PMID- 29197061 TI - Influence of technological and municipal wastewaters on vulnerable karst riverine system, Krka River in Croatia. AB - Exceptional natural value of karst rivers, as well as their potential as a source of drinking water supply, contributes to the importance of developing strict environmental protection. Although most of its watercourse is proclaimed national park, Krka River is impacted by technological and municipal wastewaters, which are released without proper purification only 2 km upstream of the park border. In order to assess water ecological status of the Krka River, vulnerability of karst ecosystem and potential threat to the Krka National Park, spatial and temporal variability of physico-chemical and microbiological water parameters, as well as concentrations of 25 total dissolved metals/metalloids were evaluated. All parameters indicated deteriorated water quality near the wastewater influences, which was for certain metals and bacterial counts even comparable to other world rivers of technological/rural catchment. Downstream location pointed to purification processes in karst river, although nutrients and conductivity were still in a range below good water quality and Al, Co, Fe, Li, Mn, Ni, Sr, Ti, and Zn levels remained comparable to their levels in the pollution impacted area, especially in autumn, indicating season-dependent processes. Presented data provided background status and identified pollution influences in the karst riverine system which indicated potential risk for protected area and a need for comprehensive water quality assessment. PMID- 29197062 TI - Clustering pesticides according to their molecular properties, fate, and effects by considering additional ecotoxicological parameters in the TyPol method. AB - Understanding the fate and ecotoxicological effects of pesticides largely depends on their molecular properties. We recently developed "TyPol" (Typology of Pollutants), a classification method of organic compounds based on statistical analyses. It combines several environmental (sorption coefficient, degradation half-life) and one ecotoxicological (bioconcentration factor) parameters, to structural molecular descriptors (number of atoms in the molecule, molecular surface, dipole moment, energy of orbitals, etc.). The present study attempts to extend TyPol to the ecotoxicological effects of pesticides on non-target organisms, based on data analysis from available literature and databases. It revealed that relevant ecotoxicological endpoints for terrestrial organisms (e.g., soil microorganisms, invertebrates) that support a range of ecosystemic services are lacking as compared to aquatic organisms. The availability of ecotoxicological parameters was also lower for chronic than for acute ecotoxicity endpoints. Consequently, seven parameters were included for acute (EC50, LC50) and chronic (NOEC) ecotoxicological effects for one terrestrial (Eisenia sp.) and three aquatic (Daphnia sp., algae, Lemna sp.) organisms. In this new configuration, we used TyPol to classify 50 pesticides into different clusters that gather molecules with similar environmental behaviors and ecotoxicological effects. The classification results evidenced relationships between molecular descriptors, environmental parameters, and the added ecotoxicological endpoints. This proof-of-concept study also showed that TyPol in silico classification can successfully address new scientific questions and be expanded with other parameters of interest.

AB - The present study was designed to detect the effect of heavy metals in two zones of the Metropolitan Area of Mexico City (MAMC), the Centro de Ciencias de la Atmosfera (CCA), and the Altzomoni station in the Iztaccihuatl-Popocatepetl National Park. Taraxacum officinale was selected as the indicator organism of responses to atmospheric contamination by heavy metals. Determinations of heavy metals were performed, and total mRNA was extracted to quantify the expression of microRNA398 (miR398), superoxide dismutase 2 (CSD2), and the amounts of free radicals using the bromide of 3-(4,5-dimethylthiazole-2-ilo)-2,5 diphenyltetrazole (MTT) salts reduction assay. Results from the Altzomoni station showed high concentrations of five heavy metals, especially Aluminum, while three heavy metals were identified in the CCA-UNAM zone, most importantly, Vanadium, both in the dry season; miR398 expression presented subtle changes but was greater in the leaves from the stations with higher concentrations of heavy metals. Observations included a significant expression of CSD2, mainly in the dry season in both study zones, where levels were significant with respect to controls (p < 0.05). Reduced MTT was also higher in the dry season than in the rainy season (p < 0.05). In conclusion, the increase in heavy metals on the leaves of Taraxacum officinale induces increased expression of the CSD2 gene and reduced MTT; thus, they can be used as indicators for biomonitoring heavy metal concentrations. PMID- 29197064 TI - Postnatal Subacute Benzo(a)Pyrene Exposure Caused Neurobehavioral Impairment and Metabolomic Changes of Cerebellum in the Early Adulthood Period of Sprague-Dawley Rats. AB - Benzo(a)pyrene (BaP) is a widespread environmental contaminant that has been associated with neurotoxicity in mammals. It has strong toxic effects on the developing central nervous system. Cerebellum is associated with locomotor activity and anxiety behavior, but there is very little research about the toxic effects of BaP in cerebellum. The present study aims to investigate the global influence of BaP subacute exposure on the metabolome of rat cerebellum. Male neonatal rats (postnatal day 5) were divided into two groups: control group and BaP-treated group (2 mg/kg/day for 7 weeks). Open field test and transmission electron microscopy were performed to analyze neurobehavior and ultramicrostructure alteration. Gas chromatography-mass spectrometry (GC-MS) was used to analyze metabolites of the cerebellum in both groups. The results revealed that postnatal exposure to BaP promoted pathological changes in the cerebellum and increased locomotor and anxiety activities in early adulthood. Twenty differential significant metabolites were identified by multivariate statistical analysis. Further metabolic pathway impact analysis and network analysis suggested that the primary metabolic pathways affected included pathway involved in energy metabolism, methionine and cysteine metabolism, and glutathione metabolism. These findings suggest that BaP-induced cerebellum injury may be correlated with metabolic changes and provide an area to target to reduce the negative effects of BaP. PMID- 29197065 TI - Exosomes from heat-stressed tumour cells inhibit tumour growth by converting regulatory T cells to Th17 cells via IL-6. AB - Exosomes derived from heat-stressed tumour cells (HS-TEXs), which contain abundant heat shock protein (HSP) 70, strongly induce antitumour immune responses. HSP70-induced interleukin (IL)-6 promotes IL-17 expression and causes rejection of established prostate tumours. However, it remains unclear whether HS TEXs exhibit antitumour effects by converting regulatory T cells (Tregs ) into T helper type 17 (Th17) cells. In this study, we found that compared with TEXs, HS TEXs were more potent in stimulating secretion of IL-6 from dendritic cells. In vitro, IL-6 blocked tumour cell-derived transforming growth factor beta 1-induced Treg differentiation and promoted Th17 cell differentiation. HS-TEXs exerted strong antitumour effects, converting Tregs into Th17 cells with high efficiency, a process that was entirely dependent upon IL-6. Neutralization of IL-17 completely abolished the antitumour effect of TEXs, but only partially inhibited that of HS-TEXs. In addition, we found higher levels of IL-6 and IL-17 in serum from tumour patients treated with hyperthermia, and an increase in Th17 cells and a decrease in Tregs was detected in peripheral blood mononuclear cells isolated from these patients after hyperthermia. Therefore, our results demonstrate that HS-TEXs possess a powerful capacity to convert immunosuppressive Tregs into Th17 cells via IL-6, which contributes to their potent antitumour effect. PMID- 29197067 TI - Cervical cancer screening through human papillomavirus testing in community health campaigns versus health facilities in rural western Kenya. AB - OBJECTIVE: To determine the effectiveness of community health campaigns (CHCs) as a strategy for human papillomavirus (HPV)-based cervical cancer screening in rural western Kenya. METHODS: Between January and November 2016, a cluster randomized trial was carried out in 12 communities in western Kenya to investigate high-risk HPV testing offered via self-collection to women aged 25-65 years in CHCs versus government health facilities. Outcome measures were the total number of women accessing cervical cancer screening and the proportion of HPV-positive women accessing treatment. RESULTS: In total, 4944 women underwent HPV-based cervical cancer screening in CHCs (n=2898) or health facilities (n=2046). Screening uptake as a proportion of total eligible women in the population was greater in communities assigned to CHCs (60.0% vs 37.0%, P<0.001). Rates of treatment acquisition were low in both arms (CHCs 39.2%; health facilities 31.5%; P=0.408). DISCUSSION: Cervical cancer screening using HPV testing of self-collected samples reached a larger proportion of women when offered through periodic CHCs compared with health facilities. The community based model is a promising strategy for cervical cancer prevention. Lessons learned from this trial can be used to identify ways of maximizing the impact of such strategies through greater community participation and improved linkage to treatment.

PMID- 29197066 TI - Characterization of the properties of a selective, orally bioavailable autotaxin inhibitor in preclinical models of advanced stages of liver fibrosis. AB - BACKGROUND AND PURPOSE: Autotaxin (ATX) is a secreted phospholipase which hydrolyses lysophosphatidylcholine to generate lysophosphatidic acid (LPA). The extracellular signalling molecule LPA exerts its biological actions through activation of six GPCRs expressed in various cell types including fibroblasts. Multiple preclinical studies using knockout animals, LPA receptor antagonists or ATX inhibitors have provided evidence for a potential role of the ATX/LPA axis in tissue fibrosis. Despite growing evidence for a correlation between ATX levels and the degree of fibrosis in chronic liver diseases, including viral hepatitis and hepatocellular carcinoma, the role of ATX in non-alcoholic steatohepatitis (NASH) remains unclear. EXPERIMENTAL APPROACH: The relevance of ATX in the pathogenesis of liver fibrosis was investigated by oral administration of Ex_31, a selective ATX inhibitor, in a 10 week model of carbon tetrachloride-induced liver injury and in a 14 week model of choline-deficient amino acid-defined diet induced liver injury in rats. KEY RESULTS: Oral administration of Ex_31, a selective ATX inhibitor, at 15 mg.kg-1 twice daily in therapeutic intervention mode resulted in efficient ATX inhibition and more than 95% reduction in plasma LPA levels in both studies. Treatment with Ex_31 had no effect on biomarkers of liver function, inflammation, or fibrosis and did not result in histological improvements in diseased animals. CONCLUSIONS AND IMPLICATIONS: Our findings question the role of ATX in the pathogenesis of hepatic fibrosis and the potential of small molecule ATX inhibitors for the treatment of patients with NASH and advanced stages of liver fibrosis. PMID- 29197068 TI - Drivers of advanced stage at breast cancer diagnosis in the multicountry African breast cancer - disparities in outcomes (ABC-DO) study. AB - Breast cancer (BC) survival rates in sub-Saharan Africa (SSA) are low in part due to advanced stage at diagnosis. As one component of a study of the entire journey of SSA women with BC, we aimed to identify shared and setting-specific drivers of advanced stage BC. Women newly diagnosed in the multicountry African Breast Cancer-Disparities in Outcomes (ABC-DO) study completed a baseline interview and their stage information was extracted from medical records. Ordinal logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) for advanced stage (I, II, III, IV) in relation to individual woman-level, referral and biological factors. A total of 1795 women were included from Nigeria, Uganda, Zambia, and the multiracial populations of Namibia and South Africa, 1091 of whom (61%) were stage III/IV. Stage was lower in women with greater BC knowledge (OR 0.77 (95% CI: 0.70, 0.85) per point on a 6 point scale). More advanced stage was associated with being black (4.00 (2.79, 5.74)), having attended = 1 year (OR 2.47 (1.93, 3.15)). These findings provide further evidence that late-stage BC in SSA is largely attributed to modifiable factors and strategies to improve BC education and awareness in women and the health system should be intensified. PMID- 29197069 TI - Polymethoxyflavones prevent benzo[a]pyrene/dextran sodium sulfate-induced colorectal carcinogenesis through modulating xenobiotic metabolism and ameliorate autophagic defect in ICR mice. AB - Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental carcinogenic pollutants and they have become an important issue in food contamination. Dietary intake of PAHs has been recognized as a major route of human exposure. However, the mechanisms behind dietary PAH-induced colorectal cancer (CRC) remain unclear. Several studies have shown that polymethoxyflavones (PMFs) are effective in preventing carcinogen-induced CRC or colitis. In this study, we investigated the preventive effect of PMFs on benzo[a]pyrene/dextran sulfate sodium (BaP/DSS) induced colorectal tumorigenesis in ICR mice. We found that PMFs significantly prevented BaP/DSS-induced colorectal tumor formation. BaP mutagenic metabolite and DNA adducts were found to be reduced in colonic tissue in the PMFs-treated groups through the modulation of BaP metabolism. At the molecular level, the results of RNA-sequencing indicated that PMFs ameliorated BaP/DSS-induced abnormal molecular mechanism change including activated inflammation, downregulated anti-oxidation targets, and induced metastasis genes. The autophagic defect caused by BaP/DSS-induced tumorigenesis was improved by pretreatment with PMFs. We found BaP/DSS-induced CRC may be a Wnt/beta-catenin independent process. Additionally, consumption of PMFs extracts also altered the composition of gut microbiota and made it similar to that in the control group by increasing butyrate-producing probiotics and decreasing CRC-related bacteria. BaP in combination with DSS significantly induced colorectal tumorigenesis through induced DNA adduct formation, abnormal gene expression, and imbalanced gut microbiota composition. PMFs were a powerful preventive agent that suppressed BaP/DSS-induced CRC via modulating multiple pathways as well as ameliorating autophagic defect. These results demonstrated for the first time the chemopreventive efficacy and comprehensive mechanisms of dietary PMFs for preventing BaP/DSS-induced colorectal carcinogenesis. PMID- 29197070 TI - The role of oxidative stress in Friedreich's ataxia. AB - Oxidative stress and an increase in the levels of free radicals are important markers associated with several pathologies, including Alzheimer's disease, cancer and diabetes. Friedreich's ataxia (FRDA) is an excellent paradigmatic example of a disease in which oxidative stress plays an important, albeit incompletely understood, role. FRDA is a rare genetic neurodegenerative disease that involves the partial silencing of frataxin, a small mitochondrial protein that was completely overlooked before being linked to FRDA. More than 20 years later, we now know how important this protein is in terms of being an essential and vital part of the machinery that produces iron-sulfur clusters in the cell. In this review, we revisit the most important steps that have brought us to our current understanding of the function of frataxin and its role in disease. We discuss the current hypotheses on the role of oxidative stress in FRDA and review some of the existing animal and cellular models. We also evaluate new techniques that can assist in the study of the disease mechanisms, as well as in our understanding of the interplay between primary and secondary phenotypes. PMID- 29197071 TI - Peroxisome proliferator-activated receptor gamma agonists for preventing recurrent stroke and other vascular events in people with stroke or transient ischaemic attack. AB - BACKGROUND: Peroxisome proliferator-activated receptor gamma (PPAR-gamma) agonists are insulin-sensitising drugs used for the treatment of insulin resistance. In addition to lowering glucose in diabetes, these drugs may also protect against hyperlipidaemia and arteriosclerosis, which are risk factors for stroke. This is an update of a review first published in January 2014 and subsequently updated in October 2015. OBJECTIVES: To assess the efficacy and safety of PPAR-gamma agonists in the secondary prevention of stroke and related vascular events for people with stroke or transient ischaemic attack (TIA). SEARCH METHODS: We searched the Cochrane Stroke Group Trials Register (16 May 2017), the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 5), MEDLINE (1949 to 16 May 2017), Embase (1980 to 16 May 2017), CINAHL (1982 to 16 May 2017), AMED (1985 to 16 May 2017), and 11 Chinese databases (16 May 2017). In an effort to identify further published, unpublished, and ongoing trials, we searched ongoing trials registers, reference lists, and relevant conference proceedings, and contacted authors and pharmaceutical companies. We did not impose any language restrictions. SELECTION CRITERIA: We included randomised controlled trials (RCTs) evaluating PPAR-gamma agonists versus placebo for the secondary prevention of stroke and related vascular events in people with stroke or TIA, with the outcomes of recurrent stroke, vascular events, and adverse events. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the titles and abstracts of identified records, selected studies for inclusion, extracted eligible data, cross-checked the data for accuracy, and assessed methodological quality and risk of bias. We evaluated the quality of evidence for each outcome using the GRADE approach. MAIN RESULTS: We identified five RCTs with 5039 participants; two studies had a low risk of bias for all domains. Four studies evaluated the drug pioglitazone, and one study evaluated rosiglitazone. The participants in different studies were heterogeneous.Recurrent strokeThree studies evaluated the number of participants with recurrent stroke (4979 participants, a single study contributing 3876 of these). Peroxisome proliferator activated receptor gamma agonists probably reduce the recurrence of stroke compared with placebo (risk ratio (RR) 0.66, 95% confidence interval (CI) 0.44 to 0.99; moderate-quality evidence).Adverse eventsEvidence that adverse events occurred more frequently in participants treated with PPAR-gamma agonists when compared with placebo was uncertain due to wide confidence interval and high levels of statistical heterogeneity: risk difference 10%, 95% CI -8% to 28%; low quality evidence).Data were available on additional composite outcomes reflecting serious vascular events (all-cause death and other major vascular events; all cause mortality, non-fatal myocardial infarction or non-fatal stroke) from one study in 984 people. This study provided low-quality evidence that PPAR-gamma agonists led to fewer events (data not meta-analysed).Vascular eventsPeroxisome proliferator-activated receptor gamma agonists given over a mean duration of 34.5 months in a single trial of 984 participants may reduce serious vascular events expressed as a composite outcome of total events of cardiovascular death, non fatal myocardial infarction or non-fatal stroke (RR 0.73, 95% CI 0.54 to 0.99; low-quality evidence).Other outcomesOne study in 20 people measured insulin sensitivity, and one study in 40 people measured the ubiquitin-proteasome activity in carotid plaques. Our confidence in the improvements observed with PPAR-gamma agonists were limited by small sample sizes and risk of bias. None of the studies reported the number of participants with disability due to vascular events or improvement in quality of life. AUTHORS' CONCLUSIONS: Peroxisome proliferator-activated receptor gamma agonists probably reduce recurrent stroke and total events of cardiovascular death, non-fatal myocardial infarction or non fatal stroke, and may improve insulin sensitivity and the stabilisation of carotid plaques. Their effects on adverse events are uncertain. Our conclusions should be interpreted with caution considering the small number and the quality of the included studies. Further well-designed, double-blind RCTs with large samples are required to assess the efficacy and safety of PPAR-gamma agonists in the secondary prevention of stroke and related vascular events in people with stroke or TIA.

PMID- 29197072 TI - Induction of mast cell accumulation by chymase via an enzymatic activity- and intercellular adhesion molecule-1-dependent mechanism. AB - BACKGROUND AND PURPOSE: Chymase is a unique, abundant secretory product of mast cells and a potent chemoattractant for eosinophils, monocytes and neutrophils, but little is known of its influence on mast cell accumulation. EXPERIMENTAL APPROACH: A mouse peritoneal inflammation model, cell migration assay and flowcytometry analysis, were used to investigate the role of chymase in recruiting mast cells. KEY RESULTS: Chymase increased, by up to 5.4-fold, mast cell numbers in mouse peritoneum. Inhibitors of chymase, heat-inactivation of the enzyme, sodium cromoglycate and terfenadine, and pretreatment of mice with anti intercellular adhesion molecule 1, anti-L-selectin, anti-CD11a and anti-CD18 antibodies dramatically diminished the chymase-induced increase in mast cell accumulation. These findings indicate that this effect of chymase is dependent on its enzymatic activity and activation of adhesion molecules. In addition, chymase provoked a significant increase in 5-HT and eotaxin release (up to 1.8- and 2.2 fold, respectively) in mouse peritoneum. Since 5-HT, eotaxin and RANTES can induce marked mast cell accumulation, these indirect mechanisms may also contribute to chymase-induced mast cell accumulation. Moreover, chymase increased the trans-endothelium migration of mast cells in vitro indicating it also acts as a chemoattractant. CONCLUSION AND IMPLICATIONS: The finding that mast cells accumulate in response to chymase implies further that chymase is a major pro inflammatory mediator of mast cells. This effect of chymase, a major product of mast cell granules, suggests a novel self-amplification mechanism for mast cell accumulation in allergic inflammation. Mast cell stabilizers and inhibitors of chymase may have potential as a treatment of allergic disorders. PMID- 29197074 TI - Bullous pemphigoid complicated by cytomegalovirus disease as a manifestation of immune reconstitution inflammatory syndrome: retrospective analyses of our institutional cases and literature review. AB - BACKGROUND: Cytomegalovirus (CMV) disease induced by reactivation of latent CMV is a fatal viral infection that may develop in a setting of therapy with immunosuppressive agents. There is a clear need to clarify any clinical features and markers of CMV disease. OBJECTIVE: We investigated which clinical markers usually available in a clinical setting can predict CMV disease occurring in bullous pemphigoid (BP) patients receiving corticosteroids. METHOD: We described a BP patient with CMV disease complicated by gastrointestinal hemorrhage and liver dysfunction. Prompted by this patient, we retrospectively analyzed clinical features and laboratory findings in our institutional four BP patients and previously reported nine BP patients with CMV disease. We also compared these patients with our institutional 42 BP patients not complicated by CMV disease. RESULTS: High levels of anti-BP180 antibody titers associated with resistance to corticosteroids are a risk factor for the development of CMV disease. A reduction in platelet (PLT) and white blood cell (WBC) counts and an increase in alanine aminotransferase (ALT) levels 3-4 weeks after the initiation of corticosteroids are useful predictive markers for the onset of CMV disease. CONCLUSIONS: Frequent WBC, PLT, and ALT measurements may identify BP patients at a risk of subsequently developing CMV disease. Careful monitoring of CMV disease in BP refractory to systemic corticosteroids may reduce the risk of fatal outcomes. PMID- 29197075 TI - The "Batman flap": a novel technique to repair a large central glabellar defect. AB - BACKGROUND: Given the critical position of central glabella among the frontal, nasal, and supraorbital aesthetic subunits of the face, the reconstruction of large defects in this area represents a surgical challenge. METHODS: We describe a surgical technique based on a modified, curved, A-T flap to repair a large glabellar defect. RESULTS: Our modification is useful for large glabellar defects because it enables the distribution of the tension all over the reconstruction sides, avoiding a stressed central area and the subsequent risk of necrosis; functionally, it respects the eyebrows position and since the advancement is parallel to their major axes, it avoids the reduction of the distance between them. CONCLUSIONS: The "Batman flap" enables reconstructing a glabellar defect, with a good aesthetical result and the respect of the relevant aesthetical subunits. PMID- 29197076 TI - DNA methylation-based biological aging and cancer risk and survival: Pooled analysis of seven prospective studies. AB - The association between aging and cancer is complex. Recent studies have developed measures of biological aging based on DNA methylation and called them "age acceleration." We aimed to assess the associations of age acceleration with risk of and survival from seven common cancers. Seven case-control studies of DNA methylation and colorectal, gastric, kidney, lung, prostate and urothelial cancer and B-cell lymphoma nested in the Melbourne Collaborative Cohort Study were conducted. Cancer cases, vital status and cause of death were ascertained through linkage with cancer and death registries. Conditional logistic regression and Cox models were used to estimate odds ratios (OR) and hazard ratios (HR) and 95% confidence intervals (CI) for associations of five age acceleration measures derived from the Human Methylation 450 K Beadchip assay with cancer risk (N = 3,216 cases) and survival (N = 1,726 deaths), respectively. Epigenetic aging was associated with increased cancer risk, ranging from 4% to 9% per five-year age acceleration for the 5 measures considered. Heterogeneity by study was observed, with stronger associations for risk of kidney cancer and B-cell lymphoma. An associated increased risk of death following cancer diagnosis ranged from 2% to 6% per five-year age acceleration, with no evidence of heterogeneity by cancer site. Cancer risk and mortality were increased by 15-30% for the fourth versus first quartile of age acceleration. DNA methylation-based measures of biological aging are associated with increased cancer risk and shorter cancer survival, independently of major health risk factors. PMID- 29197078 TI - Cardiopulmonary anomalies in incontinentia pigmenti patients. AB - BACKGROUND: Incontinentia pigmenti (IP) is a rare inherited genodermatosis that usually involves the skin, and also teeth, oral cavity, central nervous system, eyes, blood with eosinophilia, and rarely skeletal system, breast, heart, and lungs. Skin lesions usually appear early, at birth or within the first 2 weeks of life, with four different phases tending to follow Blaschko lines that may overlap. CASE REPORT: We report a rare case of a neonate with transient reversible pulmonary hypertension that presented at day 9 of life. She manifested increasing dyspnea and deterioration of respiratory dynamics with a serious pulmonary hypertension without a primary pulmonary disease. Hence, oxygen therapy at high flows and nitric oxide have been administered with an initial response, but, subsequently, because of the worsening of the respiratory activity, she underwent sildenafil and bosentan treatment with respiratory dynamics improvement and progressive decrease of the pulmonary pressures. CONCLUSION: In literature only a few cases of cardiopulmonary anomalies in IP have been described with different outcomes, and these rare complications are probably underestimated by physicians. We could suppose that microangiopathic damages may have a critical role in endothelial alterations, and these processes are probably shared by multiple organs involved in IP and rarely by lungs and heart. PMID- 29197079 TI - Postoperative outcomes following cardiac surgery in non-anaemic iron-replete and iron-deficient patients - an exploratory study. AB - Iron deficiency anaemia is strongly associated with poor outcomes after cardiac surgery. However, pre-operative non-anaemic iron deficiency (a probable anaemia precursor) has not been comprehensively examined in patients undergoing cardiac surgery, despite biological plausibility and evidence from other patient populations of negative effect on outcome. This exploratory retrospective cohort study aimed to compare an iron-deficient group of patients undergoing cardiac surgery with an iron-replete group. Consecutive non-anaemic patients undergoing elective coronary artery bypass grafting or single valve replacement in our institution between January 2013 and December 2015 were considered for inclusion. Data from a total of 277 patients were analysed, and were categorised by iron status and blood haemoglobin concentration into iron-deficient (n = 109) and iron replete (n = 168) groups. Compared with the iron-replete group, patients in the iron-deficient group were more likely to be female (43% vs. 12%, iron-replete, respectively); older, mean (SD) age 64.4 (9.7) vs. 63.2 (10.3) years; and to have a higher pre-operative EuroSCORE (median IQR [range]) 3 (2-5 [0-10]) vs. 3 (2-4 [0-9]), with a lower preoperative haemoglobin of 141.6 (11.6) vs. 148.3 (11.7) g.l-1 . Univariate analysis suggested that iron-deficient patients had a longer hospital length of stay (7 (6-9 [2-40]) vs. 7 (5-8 [4-23]) days; p = 0.013) and fewer days alive and out of hospital at postoperative day 90 (83 (80-84 [0-87]) vs. 83 (81-85 [34-86]), p = 0.009). There was no evidence of an association between iron deficiency and either lower nadir haemoglobin or higher requirement for blood products during inpatient stay. After adjusting the model for pre operative age, sex, renal function, EuroSCORE and haemoglobin, the mean increase in hospital length of stay in the iron-deficient group relative to the iron replete group was 0.86 days (bootstrapped 95%CI -0.37 to 2.22, p = 0.098). This exploratory study suggests there is weak evidence of an association between non anaemic iron deficiency and outcome after cardiac surgery after controlling for potentially confounding variables.

AB - The optimum time interval for 10 ml boluses of bupivacaine 0.0625% + fentanyl 2 MUg.ml-1 as part of a programmed intermittent epidural bolus regimen has been found to be 40 min. This regimen was shown to be effective without the use of supplementary patient-controlled epidural analgesia boluses in 90% of women during the first stage of labour, although with a rate of sensory block to ice above T6 in 34% of women. We aimed to determine the optimum programmed intermittent epidural bolus volume at a 40 min interval to provide effective analgesia in 90% of women (EV90 ) during the first stage of labour, without the use of patient-controlled epidural analgesia. We performed a prospective double blind dose-finding study using the biased coin up-and-down sequential allocation method in 40 women. The estimated EV90 was 11.0 (95%CI 10.0-11.7) ml with the isotonic regression method and 10.7 (95%CI 10.3-11.0) ml with the truncated Dixon and Mood method. Overall, 18 women had a sensory block above T6, and 37 women exhibited no motor block. No women required treatment for hypotension. In conclusion, it is not possible to reduce the programmed intermittent epidural bolus volume from 10 ml, used in our current regimen, without compromising the quality of analgesia. Using this regimen, a high proportion of women will develop a sensory block above T6. PMID- 29197077 TI - Coevolving MAPK and PID phosphosites indicate an ancient environmental control of PIN auxin transporters in land plants. AB - Plant growth flexibly adapts to environmental conditions, implying cross-talk between environmental signalling and developmental regulation. Here, we show that the PIN auxin efflux carrier family possesses three highly conserved putative mitogen-activated protein kinase (MAPK) sites adjacent to the phosphorylation sites of the well-characterised AGC kinase PINOID, which regulates the polar localisation of PINs and directional auxin transport, thereby underpinning organ growth. The conserved sites of PIN1 are phosphorylated in vitro by two environmentally activated MAPKs, MPK4 and MPK6. In contrast to AGC kinases, MAPK mediated phosphorylation of PIN1 at adjacent sites leads to a partial loss of the plasma membrane localisation of PIN1. MAPK-mediated modulation of PIN trafficking may participate in environmental adjustment of plant growth.

AB - Nearly 20 years have passed since the US Food and Drug Administration (FDA) approved the first companion diagnostic and today this type of assay governs the use of 21 different anticancer drugs. The regulators deem these assays essential for the safe and effective use of a corresponding therapeutic product. The companion diagnostic assays are important both during the drug development process as well as essential treatment decision tools after the approval of the drugs. PMID- 29197082 TI - Pupylation of PafA or Pup inhibits components of the Pup-Proteasome System. AB - The pupylation of cellular proteins plays a crucial role in the degradation cascade via the Pup-Proteasome system (PPS). It is essential for the survival of Mycobacterium smegmatis under nutrient starvation and, as such, the activity of many components of the pathway is tightly regulated. Here, we show that Pup, like ubiquitin, can form polyPup chains primarily through K61 and that this form of Pup inhibits the ATPase-mediated turnover of pupylated substrates by the 20S proteasome. Similarly, the autopupylation of PafA (the sole Pup ligase found in mycobacteria) inhibits its own enzyme activity; hence, pupylation of PafA may act as a negative feedback mechanism to prevent substrate pupylation under specific cellular conditions. PMID- 29197083 TI - Changes in ultrasonography indicators of abnormally invasive placenta during pregnancy. AB - OBJECTIVE: To ascertain whether the prevalence of ultrasonography signs of abnormally invasive placenta (AIP) changes during pregnancy. METHODS: The present retrospective analysis included women with a prenatal diagnosis of AIP that was confirmed at delivery between January 1, 2007, and April 30, 2017, at the Department of Obstetrics and Gynaecology, Arnas Civico Hospital, Palermo, Italy. Ultrasonography signs of AIP were recorded at four different intervals during pregnancy: early first (6-9 weeks), first (11-14 weeks), second (15-24 weeks), and third trimester (25-36 weeks). RESULTS: There were 105 pregnancies included. Low implantation of the gestational sac was present on all ultrasonography images from the early first trimester compared with on 23 of 83 (27.7%) images from 11 14 weeks of pregnancy. The identification of loss of the clear space, placental lacunae, bladder wall interruption, and uterovesical hypervascularity all increased (all P<0.001) from the early first trimester onwards; these could all be identified in a majority of patients at 11-14 weeks of pregnancy. CONCLUSIONS: The prevalence of ultrasonography signs suggestive of AIP varied throughout pregnancy. During the early first trimester, indicators of AIP were similar to those of a cesarean scar pregnancy; classical ultrasonography signs of AIP were already present at 11-14 weeks of pregnancy for most patients.

AB - OBJECTIVE: To determine the diagnostic value of vaginal discharge concentrations of beta human chorionic gonadotropin (beta-hCG), creatinine, and urea to identify premature rupture of membranes (PROM). METHODS: An observational cross-sectional study was conducted between 12 June, 2014, and 11 June, 2015, among 120 women who were admitted to an Iranian hospital at 28-41 weeks of pregnancy. Women with positive pooling and nitrazine test results were assigned to the PROM group (n=60), whereas those with negative test results were assigned to the control group (n=60). Samples of vaginal discharge were obtained. RESULTS: Mean concentrations of beta-hCG, urea, and creatinine were all higher in the PROM group than in the control group (all P=0.001). The diagnostic accuracies as defined by area under the curve for creatinine, urea, and beta-hCG were 0.891, 0.895, and 0.908, respectively. The corresponding optimal cutoff values were 20.33 MUmol/L, 0.94 mmol/L, and 39.5 IU/L, respectively. CONCLUSION: The vaginal discharge concentrations of all three markers exhibited favorable predictive value for the diagnosis of PROM; however, beta-hCG showed greater diagnostic accuracy than either urea or creatinine. PMID- 29197086 TI - Methylation of OPRL1 mediates the effect of psychosocial stress on binge drinking in adolescents. AB - BACKGROUND: Nociceptin is a key regulator linking environmental stress and alcohol drinking. In a genome-wide methylation analysis, we recently identified an association of a methylated region in the OPRL1 gene with alcohol-use disorders. METHODS: Here, we investigate the biological basis of this observation by analysing psychosocial stressors, methylation of the OPRL1 gene, brain response during reward anticipation and alcohol drinking in 660 fourteen-year-old adolescents of the IMAGEN study. We validate our findings in marchigian sardinian (msP) alcohol-preferring rats that are genetically selected for increased alcohol drinking and stress sensitivity. RESULTS: We found that low methylation levels in intron 1 of OPRL1 are associated with higher psychosocial stress and higher frequency of binge drinking, an effect mediated by OPRL1 methylation. In individuals with low methylation of OPRL1, frequency of binge drinking is associated with stronger BOLD response in the ventral striatum during reward anticipation. In msP rats, we found that stress results in increased alcohol intake and decreased methylation of OPRL1 in the nucleus accumbens. CONCLUSIONS: Our findings describe an epigenetic mechanism that helps to explain how psychosocial stress influences risky alcohol consumption and reward processing, thus contributing to the elucidation of biological mechanisms underlying risk for substance abuse. PMID- 29197089 TI - Nuclease-resistant 63-bp trimeric siRNAs simultaneously silence three different genes in tumor cells. AB - We designed a multimeric nuclease-resistant 63-bp trimeric small-interfering RNA (tsiRNA) comprising in one duplex the sequence of siRNAs targeting mRNAs of MDR1, LMP2, and LMP7 genes. We show that such tsiRNA is able to suppress the expression of all the target genes independently and with high efficiency, acting via a Dicer-dependent mechanism. tsiRNA is diced into 42- and 21-bp duplexes inside the cell. tsiRNA-induced gene silencing is characterized by kinetics similar to that of canonical siRNA, while the silencing efficiency is significantly higher than that of canonical siRNA with the same sequence. PMID- 29197090 TI - Syndrome of Transient Headache and Neurologic Deficits With Cerebrospinal Fluid Lymphocitosis Should Be Considered in Children Presenting With Acute Confusional State. AB - BACKGROUND: Transient headache and neurologic deficits with cerebrospinal fluid lymphocytosis (HaNDL) is benign and self-limited, with neurologic deficits including sensory disturbance of one body side, aphasia, nausea/vomiting, weakness, decreased vision, homonymous hemianopsia, photophobia. Acute confusional state can rarely occur. Papilledema and intracranial hypertension have also been described. It is a rare entity mainly affecting adults; however, it has been sporadically described in children and adolescents. MAIN FINDINGS: In this clinical observational study, we describe a clinical series of three consecutive pediatric patients being diagnosed with HaNDL after presenting with altered consciousness, papilledema, and increased intracranial pressure. They all recovered without relapses. CONCLUSION: Presentation during childhood and adolescence is rare; the majority of pediatric cases presented with altered consciousness, which is infrequent in HaNDL. This may suggest that in childhood this symptom might be more common than in adults. All three patients presented with increased intracranial pressure and papilledema, thus suggesting that these aspects should be investigated in all patients presenting with this clinical pattern. Finally, all our patients began to suffer from migraine. This feature, together with the benign course of the disease, could favor the hypothesis of a migrainous pathophysiology of this syndrome, although this remains a speculative. PMID- 29197088 TI - Inhibition of MK2 suppresses IL-1beta, IL-6, and TNF-alpha-dependent colorectal cancer growth. AB - Colorectal cancer (CRC) development and progression is associated with chronic inflammation. We have identified the MAPK-activated protein kinase 2 (MK2) pathway as a primary mediator of inflammation in CRC. MK2 signaling promotes production of proinflammatory cytokines IL-1beta, IL-6 and TNF-alpha. These cytokines have been implicated in tumor growth, invasion and metastasis. For the first time, we investigate whether MK2 inhibition can improve outcome in two mouse models of CRC. In our azoxymethane/dextran sodium sulfate (AOM/DSS) model of colitis-associated CRC, MK2 inhibitor treatment eliminated murine tumor development. Using the implanted, syngeneic murine CRC cell line CT26, we observe significant tumor volume reduction following MK2 inhibition. Tumor cells treated with MK2 inhibitors produced 80% less IL-1beta, IL-6 and TNF-alpha and demonstrated decreased invasion. Replenishment of downstream proinflammatory MK2 mediated cytokines (IL-1beta, IL-6 and TNF-alpha) to tumors led to restoration of tumor proliferation and rapid tumor regrowth. These results demonstrate the importance of MK2 in driving proinflammatory cytokine production, its relevance to in vivo tumor proliferation and invasion. Inhibition of MK2 may represent an attractive therapeutic target to suppress tumor growth and progression in patients. PMID- 29197091 TI - Cost-effectiveness of cognitive therapy as an early intervention for post traumatic stress disorder in children and adolescents: a trial based evaluation and model. AB - BACKGROUND: Untreated post-traumatic stress disorder (PTSD) in children and adolescents is associated with a considerable economic burden on the health system, families and society. Recent research has demonstrated the potential efficacy of cognitive therapy as an early intervention for PTSD in children and adolescents. Children who experienced a single traumatic event in the previous two to six months and were randomized to cognitive therapy for PTSD (CT-PTSD) were significantly more likely to be PTSD-free compared to those randomized to usual care represented by waitlist control. The current study evaluated the economic impact of improvements in the treatment of PTSD in children and adolescents. METHODS: A cost-effectiveness analysis was conducted from the national health service/personal social services perspective with outcomes expressed as quality-adjusted life years (QALYs). Patient level costs and outcomes were collected during the 11 week clinical trial and extrapolated to a three year time horizon using economic modelling methods. Uncertainty was estimated using probabilistic sensitivity analysis and assumptions were tested using one way sensitivity analysis. RESULTS: The incremental cost-effectiveness ratio at 3 years was L2,205 per QALY with a 60%-69% probability of CT-PTSD being cost-effective compared to usual care at the UK L20,000 to L30,000 per QALY decision threshold. CONCLUSIONS: This study provides preliminary evidence for the cost-effectiveness of cognitive therapy in this treatment population. Larger pragmatic trials with longer follow-up are indicated. PMID- 29197093 TI - The association between irisin and muscle metabolism in different thyroid disorders. AB - BACKGROUND: Irisin is a new adipo-myokine, encoded by the FNDC5 gene. Currently, there is a discussion regarding the relation between thyroid function and irisin concentration. This prospective study assesses the influence of thyrometabolic changes on serum irisin concentration in association with altered muscle metabolism. This is performed on a large cohort of patients affected by severe hypo- or hyperthyroidism, as well as by the expression of the FNDC5 gene in thyroid tissue affected by different pathologies. METHODS: The study group comprised 119 patients with newly diagnosed severe hyperthyroidism or hypothyroidism, and a control group of 45 healthy subjects. Body composition, serum irisin concentrations, and thyroid-related hormones, creatine kinase, dystrophin and titin concentrations were evaluated. FNDC5 expression was also analysed in tissue samples from 80 patients with nontoxic multinodular goitre, toxic goitre, Graves' disease and papillary thyroid cancer. RESULTS: Irisin concentration was lower in patients with prolonged hypothyroidism. There was a tendency towards lower dystrophin and titin concentrations in patients with hypothyroidism and hyperthyroidism. Restoration of euthyroidism in patients with hypothyroidism resulted in a decreased muscle mass with an increase in irisin concentrations, while the hyperthyroid group showed an increase in fat mass. Statistically significant overexpression of FNDC5 gene was found in patients with toxic goitre as compared to Graves' disease, papillary thyroid cancer and controls. CONCLUSIONS: The presented data support the theory that irisin concentration changes are associated with prolonged hypothyroidism and might primarily constitute the result of prolonged myopathy. These changes are most likely not related to the expression of the FNDC5 gene in the thyroid gland. PMID- 29197092 TI - Concomitant Psychiatric and Nonalcohol-Related Substance Use Disorders Among Hospitalized Patients with Alcoholic Liver Disease in the United States. AB - BACKGROUND: Despite that the epidemiological studies on the comorbidity of alcohol misuse and psychiatric disorders have been studied, less is known about the magnitude of these disorders among patients with alcoholic liver disease (ALD). Our aim was to determine the prevalence of psychiatric and substance use disorders among hospitalized ALD patients in the United States. METHODS: We utilized a single-level clinical classification software to identify patients with ALD and psychiatric/substance use disorders from the 2011 National Inpatient Sample data. The primary outcome was the prevalence of these disorders among hospitalized patients with ALD (n = 74,972) compared to those with chronic liver diseases not caused by alcohol (n = 350,140) and those without underlying liver diseases (n = 1,447,063). RESULTS: The prevalence of adjustment disorder, anxiety disorder, posttraumatic stress disorder, and depression was significantly higher among hospitalized patients with ALD when compared to those with chronic liver diseases not caused by alcohol (all with p-values <0.05). Younger age, female gender, and White race were the independent predictors of psychiatric/substance use disorders among hospitalized patients with ALD. CONCLUSIONS: Hospitalized patients with ALD have significantly high prevalence of concomitant psychiatric and substance abuse disorders when compared to those with chronic liver diseases not caused by alcohol and those without underlying liver diseases. Screening and appropriate intervention should be implemented as part of routine clinical care for these patients. PMID- 29197094 TI - Plasma NT-proBNP and Cell-Free DNA Concentrations after Prolonged Strenuous Exercise in Working Farm Dogs. AB - BACKGROUND: Plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentration is increased in dogs with myocardial dysfunction, and cell-free DNA (cfDNA) increases in numerous disease states. In humans, both of these biomarkers can be altered after endurance exercise. OBJECTIVE: To investigate the effect of prolonged strenuous exercise on circulating NT-proBNP and cfDNA concentrations in working farm dogs. ANIMALS: Six healthy, privately owned working farm dogs (4 Huntaways and 2 heading dogs) from the same hill country farm in New Zealand. METHODS: Prospective, nonrandomised cohort study. Venous blood samples were collected before and after the dogs worked over 4 days. Plasma NT-proBNP concentrations were measured by a commercially available ELISA assay and cfDNA concentrations were determined by fluorometry without prior DNA extraction. RESULTS: The baseline (before work, Day 1) median plasma NT-proBNP concentration was 664 pmol/L. A linear mixed-effects model showed that work increased plasma NT proBNP concentrations by 101 +/- 9% (P < 0.001), but with each consecutive day of work, NT-proBNP concentrations declined by 16 +/- 4% (P < 0.001). The baseline median plasma cfDNA concentration was 653 ng/mL, and plasma cfDNA concentrations increased by 138 +/- 45 ng/mL after work (P = 0.004). CONCLUSIONS AND CLINICAL IMPORTANCE: The plasma concentration of NT-proBNP in healthy Huntaways and heading dogs after work can exceed the upper limit of the reference range. Results in dogs sampled on the day of prolonged strenuous exercise should be interpreted with caution. Plasma concentrations of cfDNA also increase with exercise, but further studies are needed to establish reference ranges in healthy dogs. PMID- 29197095 TI - Oro-facial pain and temporomandibular disorders classification systems: A critical appraisal and future directions. AB - It is a difficult undertaking to design a classification system for any disease entity, let alone for oro-facial pain (OFP) and more specifically for temporomandibular disorders (TMD). A further complication of this task is that both physical and psychosocial variables must be included. To augment this process, a two-step systematic review, adhering to PRISMA guidelines, of the classification systems published during the last 20 years for OFP and TMD was performed. The first search step identified 190 potential citations which ultimately resulted in only 17 articles being included for in-depth analysis and review. The second step resulted in only 5 articles being selected for inclusion in this review. Five additional articles and four classification guidelines/criteria were also included due to expansion of the search criteria. Thus, in total, 14 documents comprising articles and guidelines/criteria (8 proposals of classification systems for OFP; 6 for TMD) were selected for inclusion in the systematic review. For each, a discussion as to their advantages, strengths and limitations was provided. Suggestions regarding the future direction for improving the classification process with the use of ontological principles rather than taxonomy are discussed. Furthermore, the potential for expanding the scope of axes included in existing classification systems, to include genetic, epigenetic and neurobiological variables, is explored. It is therefore recommended that future classification system proposals be based on combined approaches aiming to provide archetypal treatment-oriented classifications.

PMID- 29197096 TI - Observations on the origin of ovarian cortical inclusion cysts in women undergoing risk-reducing salpingo-oophorectomy. AB - AIMS: Evidence suggests that up to 70% of high-grade serous ovarian carcinomas (HGSCs) arise potentially from fallopian tube fimbriae, and that many of the remaining cases arise from within the ovary in cortical inclusion cysts (CICs) with a Mullerian phenotype (Mullerian-CICs). It has been proposed that Mullerian CICs arise either from metaplasia of mesothelial ovarian surface epithelium (OSE) entrapped within the ovary after ovulation or from normal tubal cells entrapped postovulation. However, this proposal is controversial. We therefore conducted a study of CICs in women, most of them BRCA1/2 mutation carriers, undergoing risk reducing salpingo-oophorectomy at our institution from 2000 to 2014. METHODS AND RESULTS: We used immunohistochemistry for PAX8, a Mullerian marker, and calretinin, a mesothelial marker to classify CIC cells. In 499 CICs from 59 women, 72.3% were positive for PAX8 (PAX8+ ): >=10% of CIC cells positive; 43.5% positive for calretinin (calretinin+ ). The proportion of PAX8+ CICs increased from 62.9% in premenopausal to 80.5% in postmenopausal patients. The proportion of calretinin+ CICs decreased from 52.6% to 35.6%, respectively. There was significant overlap of PAX8 and calretinin positivity: 82 (16.4%) CICs were PAX8+ /calretinin+ ; 43 (40.2%) of these 82 demonstrated PAX8+ /calretinin+ in the same cells. CONCLUSIONS: These results, and the increased ratio of PAX8+ to calretinin+ CICs from premenopausal to postmenopausal, show that many PAX8+ CICs probably arise from metaplasia of OSE-derived CICs. The proportion of PAX+ /calretinin- CICs arising from OSE-derived CICs is unclear, but our results strongly support the proposal that many Mullerian-CICs arise from OSE via metaplasia. PMID- 29197098 TI - A longitudinal investigation of the role of parental responses in predicting children's post-traumatic distress. AB - BACKGROUND: While parental post-trauma support is considered theoretically important for child adjustment, empirical evidence concerning the specific aspects of parental responding that influence child post-traumatic distress, or the processes via which any such impacts occur, is extremely limited. We conducted a longitudinal examination of whether parental post-trauma appraisals, trauma-specific support style and general parenting style predicted child post traumatic stress symptom severity (PTSS) following trauma; and whether such influences operated via the child's own appraisals and coping style. METHOD: We recruited 132 parent-child pairs following children's experience of acute trauma. We examined whether parental responses assessed at 1-month post-trauma, predicted child PTSS at 6-month follow-up. Parental trauma-specific appraisals and responses, and general parenting style, were assessed via both self-report and direct observations. Child-report questionnaires were used to assess PTSS and potential mediators. RESULTS: Initial parent negative appraisals and encouragement of avoidant coping were associated with higher child-reported PTSS at 6-month follow-up. Predictive effects were maintained even when controlling for initial child symptom levels. Observational assessments broadly supported conclusions from self-report. There was evidence that parental influences may operate, in part, by influencing the child's own appraisals and coping responses. In contrast, there was no evidence for an influence of more "adaptive" support or general parenting style on child PTSS. CONCLUSIONS: Findings provide important insight into how elements of social support may influence child post-trauma outcomes. PMID- 29197099 TI - Identification of patterns of factors preceding severe or life-threatening asthma exacerbations in a nationwide study. AB - BACKGROUND: Reducing near-fatal asthma exacerbations is a critical problem in asthma management. OBJECTIVES: To determine patterns of factors preceding asthma exacerbations in a real-world setting. METHODS: In a nationwide prospective study of 190 patients who had experienced near-fatal asthma exacerbation, cluster analysis was performed using asthma symptoms over the 2-week period before admission. RESULTS: Three distinct clusters of symptoms were defined employing the self-reporting of a visual analogue scale. Cluster A (42.1%): rapid worsening within 7.4 hours from moderate attack to admission, young to middle-aged patients with low Body mass index and tendency to depression who had stopped anti-asthma medications, smoked, and hypersensitive to environmental triggers and furred pets. Cluster B (40.0%): fairly rapid worsening within 48 hours, mostly middle aged and older, relatively good inhaled corticosteroid (ICS) or ICS/long-acting beta-agonist (LABA) compliance, and low perception of dyspnea. Cluster C (17.9%): slow worsening over 10 days before admission, high perception of dyspnea, smokers, and chronic daily mild-moderate symptoms. There were no differences in overuse of short-acting beta-agonists, baseline asthma severity, or outcomes after admission for patients in these 3 clusters. CONCLUSION: To reduce severe or life-threatening asthma exacerbation, personalized asthma management plans should be considered for each cluster. Improvement of ICS and ICS/LABA compliance and cessation of smoking are important in cluster A. To compensate for low perception of dyspnea, asthma monitoring of peak expiratory flow rate and/or exhaled nitric oxide would be useful for patients in cluster B. Avoidance of environmental triggers, increase usual therapy, or new anti-type 2 response-targeted therapies should be considered for cluster C. PMID- 29197101 TI - A biocompatible decellularized pulp scaffold for regenerative endodontics. AB - AIM: To investigate the feasibility of decellularizing the entire dental pulp using a mild treatment protocol to develop a decellularized biological extracellular matrix scaffold for use in regenerative endodontic procedures. METHODOLOGY: Decellularized human dental pulps were assessed using histological and immunohistochemical methods, scanning electron microscope and DNA quantification assay. Cytotoxicity assays to determine decellularized scaffold biocompatibility were also performed. Decellularized scaffolds were seeded with human dental pulp stem cells and cell viability assessed using Live/Dead(r) stain. Quantitative data were analysed statistically using Student's t-test and one-way analysis of variance to compare mean values between groups depending on group numbers. RESULTS: Assessment of decellularized tissues revealed an acellular matrix with preservation of native tissue histoarchitecture and composition. Decellularized tissues showed no evidence of cytotoxicity, with cell growth in direct contact with the scaffold and no reduction in cellular activity following extract incubation. Furthermore, the scaffold was able to support human dental pulp stem cell viability and attachment following recellularization. CONCLUSIONS: Promising results were observed in developing a decellularized biological scaffold derived from the dental pulp with the perseveration of extracellular structural components which are required for tissue-specific regeneration. PMID- 29197100 TI - The high societal costs of childhood conduct problems: evidence from administrative records up to age 38 in a longitudinal birth cohort. AB - BACKGROUND: Children with conduct problems that persist into adulthood are at increased risk for future behavioral, health, and social problems. However, the longer term public service usage among these children has not been fully documented. To aid public health and intervention planning, adult service usage across criminal justice, health care, and social welfare domains is compared among all individuals from a representative cohort who followed different conduct problem trajectories from childhood into adulthood. METHODS: Participants are from the Dunedin Multidisciplinary Health and Development Study, a prospective, representative cohort of consecutive births (N = 1,037) from April 1972 to March 1973 in Dunedin, New Zealand. Regression analyses were used to compare levels of public service usage up to age 38, gathered via administrative and electronic medical records, between participants who displayed distinct subtypes of childhood conduct problems (low, childhood-limited, adolescent-onset, and life course persistent). RESULTS: Children exhibiting life-course persistent conduct problems used significantly more services as adults than those with low levels of childhood conduct problems. Although this group comprised only 9.0% of the population, they accounted for 53.3% of all convictions, 15.7% of emergency department visits, 20.5% of prescription fills, 13.1% of injury claims, and 24.7% of welfare benefit months. Half of this group (50.0%) also accrued high service use across all three domains of criminal justice, health, and social welfare services, as compared to only 11.3% of those with low conduct problems (OR = 7.27, 95% CI = 4.42-12.0). CONCLUSIONS: Conduct problems in childhood signal high future costs in terms of service utilization across multiple sectors. Future evaluations of interventions aimed at conduct problems should also track potential reductions in health burden and service usage that stretch into midlife. PMID- 29197102 TI - Evaluation of a computerized cognitive behavioural therapy programme, MindWise (2.0), for adults with mild-to-moderate depression and anxiety. AB - OBJECTIVES: To investigate the acceptability and utility of a newly developed computerized cognitive behavioural therapy (cCBT) programme, MindWise (2.0), for adults attending Irish primary care psychology services. METHOD: Adult primary care psychology service users across four rural locations in Ireland were invited to participate in this study. A total of 60 service users participated in the MindWise (2.0) treatment group and compared to 22 people in a comparison waiting list control group. Participants completed pre- and post-intervention outcome measures of anxiety, depression, and work/social functioning. RESULTS: At post intervention, 25 of 60 people in the MindWise (2.0) condition had fully completed the programme and 19 of 22 people in the waiting list condition provided time 2 data. Relative to those in the control group, the MindWise (2.0) participants reported significantly reduced symptoms of anxiety and no change in depression or work/social functioning. CONCLUSIONS: The newly developed cCBT programme, MindWise (2.0), resulted in significant improvements on a measure of anxiety and may address some barriers to accessing more traditional face-to-face mental health services for adults in a primary care setting. Further programme development and related research appears both warranted and needed to lower programme drop-out, establish if gains in anxiety management are maintained over time, and support people in a primary care context with depression. PRACTITIONER POINTS: There is a growing evidence base that computerized self-help programmes can assist in a stepped-care approach to adult mental health service provision. These programmes require further development to address issues such as high dropout, the development of equally effective transdiagnostic content, and greater effectiveness in the country of origin. This study evaluated the acceptability and utility of a brief online CBT programme for adults referred due to anxiety or low mood to primary care psychology services in the national health service in Ireland. Results indicate that 42% of people completed the programme and experienced a significant reduction in anxiety but not depression and no improvement in work or social adjustment compared to similar adults on a waiting list for services. This study suggests the programme warrants further development and research and may in time become a useful and suitable intervention within the national health service in Ireland. PMID- 29197103 TI - Long-term variability of sleep bruxism and psychological stress in patients with jaw-muscle pain: Report of two longitudinal clinical cases. AB - Sleep bruxism (SB) and psychological stress are commonly considered as contributing factors in the aetiology of temporomandibular disorder (TMD) pain. However, the lack of longitudinal studies and fluctuating nature of SB, psychological stress and TMD pain have led to contradictory results regarding the association between the possible aetiological factors and TMD pain. In the present study we investigated the contribution of SB and psychological stress to TMD pain in a longitudinal study of 2 clinical TMD pain cases during a 6-week study protocol. Two female volunteers with clinically diagnosed myalgia based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) participated in the study. Questionnaires were used to record jaw-muscle pain and psychological stress experience, and an ambulatory polysomnography technique was used to record SB intensity. Visual analysis of the data revealed that the intensity of TMD pain was not hardwired, neither with psychological stress experience nor with increased SB activity. Within the limitations of single-patient clinical cases design, our study suggested that the presence of TMD pain cannot be explained by a simple linear model which takes psychological stress or SB into account. It also seems that psychological stress was a more important predictor factor for TMD pain than SB. PMID- 29197104 TI - The effect of dronabinol in a male patient with anorexia nervosa suffering from severe acute urge to be physically active. AB - OBJECTIVE: A 27-year-old male suffering from chronic anorexia nervosa was admitted for inpatient psychotherapy suffering from severe urge to be physically active. METHODS: An off-label treatment with dronabinol was initiated, to reduce his symptoms related to that urge. Several attempts to reduce symptoms including intensive psychotherapy and several psychopharmacological agents had failed in the past. RESULTS: Following treatment with 7.5 mg dronabinol twice a day, the patient reported a significant reduction in his acute urge to be physically active. Also eating disorder-specific cognitions and compulsive behaviors remitted. DISCUSSION: Previous studies have applied much lower doses and showed no effect of dronabinol upon the urge to be physically active. Up to date, the patient reported no side effects, especially no psychotropic effects. Implications of this case report are discussed. PMID- 29197105 TI - Upper and lower airway remodelling mechanisms in asthma, allergic rhinitis and chronic rhinosinusitis: The one airway concept revisited. AB - Allergic rhinitis (AR), chronic rhinosinusitis (CRS) and asthma often co-exist. The one airway model proposes that disease mechanisms occurring in the upper airway may mirror lower airway events. Airway remodelling is the term used to describe tissue structural changes that occur in a disease setting and reflect the dynamic process of tissue restructuring during wound repair. Remodelling has been long identified in the lower airways in asthma and is characterized by epithelial shedding, goblet cell hyperplasia, basement membrane thickening, subepithelial fibrosis, airway smooth muscle hyperplasia and increased angiogenesis. The concept of upper airway remodelling has only recently been introduced, and data so far are limited and often conflicting, an indication that more detailed studies are needed. Whilst remodelling changes in AR are limited, CRS phenotypes demonstrate epithelial hyperplasia, increased matrix deposition and degradation along with accumulation of plasma proteins. Despite extensive research over the past years, the precise cellular and molecular mechanisms involved in airway remodelling remain incompletely defined. This review describes our current rather limited understanding of airway remodelling processes in AR, CRS and asthma and presents mechanisms both shared and distinct between the upper and lower airways. Delineation of shared and disease-specific pathogenic mechanisms of remodelling between the sinonasal system and the lung may guide the rational design of more effective therapeutic strategies targeting upper and lower airways concomitantly and improving the health of individuals with inflammatory airway diseases. PMID- 29197106 TI - Practitioner Review: School refusal: developments in conceptualisation and treatment since 2000. AB - BACKGROUND: A generation has passed since the literature on the conceptualisation, assessment and treatment of school refusal was reviewed in this journal (Elliott, ). In the light of considerable gaps in the literature, identified at that time, and growing international interest, the current paper sought to identify progress subsequently made this century. METHODS: We open with discussion of continuing conceptual uncertainty as to whether school refusal should incorporate both truancy and absenteeism marked by anxiety and distress. We then consider progress in treatment, and conclude by examining prognosis and subsequent adult functioning. In selecting intervention studies for review, our primary focus has been upon RCTS, systematic reviews and meta-analyses. RESULTS: The literature review indicates that, since the turn of the century, there has been little substantial advance in knowledge that can guide practitioners. Many of the issues raised in the 1999 paper, in particular, conceptual confusion over this heterogeneous condition, a dearth of rigorous RCT designs, limited knowledge of underlying mechanisms and uncertainty as to the long-term effects of specific forms of intervention, are little clearer than before. CONCLUSIONS: While several sound publications are available to guide intervention for school refusal, there is a continuing need for rigorous studies that can provide evidence to support individualised and tailored responses to an incapacitating problem with many causes and manifestations. While a multisystemic response to intervention approach is considered attractive, the practicalities of operating this across disparate professional borders are likely to present a long-term challenge. PMID- 29197107 TI - Developmental stability of general and specific factors of psychopathology from early childhood to adolescence: dynamic mutualism or p-differentiation? AB - BACKGROUND: Recent research indicates that the best-fitting structural model of psychopathology includes a general factor capturing comorbidity (p) and several more specific, orthogonal factors. Little is known about the stability of these factors, although two opposing developmental processes have been proposed: dynamic mutualism suggests that symptom-level interaction and reinforcement may lead to a strengthening of comorbidity (p) over time, whereas p-differentiation suggests a general vulnerability to psychopathology that gives way to increasingly distinct patterns of symptoms over time. In order to test both processes, we examine two forms of developmental stability from ages 2 to 14 years: strength (i.e., consistency in the amount of variance explained by general and specific factors) and phenotypic stability (i.e., homotypic and heterotypic continuity). METHODS: Data are from the NICHD Study of Early Child Care and Youth Development. Psychopathology symptoms were assessed nine times between ages 2 and 14 years (n = 1,253) using the Child Behavior Checklist completed by mothers. Confirmatory bifactor modeling was used to test structural models of psychopathology at each age. Consistency in strength was examined by calculating the Explained Common Variance (ECV) and phenotypic stability was investigated with cross-lagged modeling of the general and specific factors. RESULTS: Bifactor models fit the data well across this developmental period. ECV values were reasonably consistent across development, with the general factor accounting for the majority of shared variance (61%-71%). Evidence of both homotypic and heterotypic continuity emerged, with most heterotypic continuity involving the general factor, as it both predicted and was predicted by specific factors. CONCLUSIONS: A bifactor model effectively captures psychopathological comorbidity from early childhood through adolescence. The longitudinal associations between the general and specific factors provide evidence for both the hypothesized processes (dynamic mutualism and p-differentiation) occurring through development. PMID- 29197108 TI - Refining a Claims-based Algorithm to Estimate Biologic Medication Effectiveness and Cost per Effectively Treated Patient with Rheumatoid Arthritis. AB - BACKGROUND: Claims data generally lack information on clinical outcomes. However, a validated claims-based algorithm for estimating the effectiveness of biologic agents in treating rheumatoid arthritis (RA) was recently developed and applied to various databases. OBJECTIVES: The objectives of the study were to implement a claims-based algorithm in a large nationwide database to estimate medication effectiveness and cost for patients with RA using biologic disease-modifying antirheumatic drugs (DMARDs) and to assess the effect of eliminating one criterion from the algorithm on results. METHODS: The DMARD groups included patients initiated on etanercept, adalimumab, abatacept, or infliximab. Patients were categorized as effectively treated if they met these six criteria: a medication possession ratio of 80% or greater; no escalation in biologic dose; no switch in biologics; no new nonbiologic DMARD; no new or increased oral glucocorticoid treatment; and no more than one glucocorticoid injection. In a follow-up analysis, the dose-escalation criterion was removed because an increase in dose for infliximab may be appropriate. Average costs for RA-related medications were calculated for each DMARD patient group and divided by the number of patients who met all six effectiveness criteria. RESULTS: A total of 1196 individuals were included in the analysis. Using the algorithm, the index biologic was categorized as effective for 25.4% of patients overall: 30.3% (102/337) of etanercept, 27.6% (104/377) of adalimumab, 32.7% (37/113) of abatacept, and 16.5% (61/369) of infliximab patients. Total costs for RA medication costs per effectively treated patient ranged from more than $80,000 for infliximab to ~$43,000-$46,000 for the other three groups. Removing the no dose-escalation criterion drastically reduced the cost per effectively treated patient in the infliximab group (to ~$42,000). CONCLUSIONS: Using the original six-criteria claims-based algorithm in a large claims database, infliximab was the least-effective biologic agent and had the highest medication cost per effectively treated patient. However, when a follow-up analysis removed the dose escalation exclusion criterion, the four groups had similar effectiveness and medication costs per effectively treated patient with RA. PMID- 29197109 TI - Prospective test of the developmental propensity model of antisocial behavior: from childhood and adolescence into early adulthood. AB - BACKGROUND: The developmental propensity model of antisocial behavior posits that several dispositional characteristics of children transact with the environment to influence the likelihood of learning antisocial behavior across development. Specifically, greater dispositional negative emotionality, greater daring, and lower prosociality-operationally, the inverse of callousness- and lower cognitive abilities are each predicted to increase risk for developing antisocial behavior. METHODS: Prospective tests of key predictions derived from the model were conducted in a high-risk sample of 499 twins who were assessed on dispositions at 10-17 years of age and assessed for antisocial personality disorder (APD) symptoms at 22-31 years of age. Predictions were tested separately for parent and youth informants on the dispositions using multiple regressions that adjusted for oversampling, nonresponse, and clustering within twin pairs, controlling demographic factors and time since the first assessment. RESULTS: Consistent with predictions, greater numbers of APD symptoms in adulthood were independently predicted over a 10-15 year span by higher youth ratings on negative emotionality and daring and lower youth ratings on prosociality, and by parent ratings of greater negative emotionality and lower prosociality. A measure of working memory did not predict APD symptoms. CONCLUSIONS: These findings support future research on the role of these dispositions in the development of antisocial behavior.

AB - Maxillectomy for oral tumours often results in debilitating oral hypofunction, which markedly decreases quality of life. Dysphagia, in particular, is one of the most serious problems following maxillectomy. This study used swallowing sounds as a simple evaluation method to evaluate swallowing ability in maxillectomy patients with and without their obturator prosthesis placed. Twenty-seven maxillectomy patients (15 men, 12 women; mean age 66.0 +/- 12.1 years) and 30 healthy controls (14 men, 16 women; mean age 44.9 +/- 21.3 years) were recruited for this study. Participants were asked to swallow 4 mL of water, and swallowing sounds were recorded using a throat microphone. Duration of the acoustic signal and duration of peak intensity (DPI) were measured. Duration of peak intensity was significantly longer in maxillectomy patients without their obturator than with it (P < .05) and was significantly longer in maxillectomy patients without their obturator than in healthy controls (P < .025 after Bonferroni correction). With the obturator placed, DPI was significantly longer in maxillectomy patients who had undergone soft palate resection than in those who had not (P < .05). These results suggest swallowing ability in maxillectomy patients could be improved by wearing an obturator prosthesis, particularly during the oral stage. However, it is difficult to improve the oral stage of swallowing in patients who have undergone soft palate resection even with obturator placement. PMID- 29197112 TI - Invasion in breast lesions: the role of the epithelial-stroma barrier. AB - Despite the significant biological, behavioural and management differences between ductal carcinoma in situ (DCIS) and invasive carcinoma of the breast, they share many morphological and molecular similarities. Differentiation of these two different lesions in breast pathological diagnosis is based typically on the presence of an intact barrier between the malignant epithelial cells and stroma; namely, the myoepithelial cell (MEC) layer and surrounding basement membrane (BM). Despite being robust diagnostic criteria, the identification of MECs and BM to differentiate in-situ from invasive carcinoma is not always straightforward. The MEC layer around DCIS may be interrupted and/or show an altered immunoprofile. MECs may be absent in some benign locally infiltrative lesions such as microglandular adenosis and infiltrating epitheliosis, and occasionally in non-infiltrative conditions such as apocrine lesions, and in these contexts this does not denote malignancy or invasive disease with metastatic potential. MECs may also be absent around some malignant lesions such as some forms of papillary carcinoma, yet these behave in an indolent fashion akin to some DCIS. In Paget's disease, malignant mammary epithelial cells extend anteriorly from the ducts to infiltrate the epidermis of the nipple but do not typically infiltrate through the BM into the dermis. Conversely, BM-like material can be seen around invasive carcinoma cells and around metastatic tumour cell deposits. Here, we review the role of MECs and BM in breast pathology and highlight potential clinical implications. We advise caution in interpretation of MEC features in breast pathology and mindfulness of the substantive evidence base in the literature associated with behaviour and clinical outcome of lesions classified as benign on conventional morphological examination before changing classification to an invasive lesion on the sole basis of MEC characteristics. PMID- 29197114 TI - The correlation between SNPs within the gene of adrenergic receptor and neuropeptide Y and risk of cervical vertigo. AB - BACKGROUND: The current investigation was aimed to explore the potential associations of SNPs within ADRB2, ADRB1, NPY, and ADRA1A with risk and prognosis of cervical vertigo. METHODS: Altogether 216 patients with cervical vertigo and 204 healthy controls were gathered, and their DNAs were extracted utilizing the whole-blood DNA extraction kit. Besides, the PCR reactions were conducted using the TaqManR single nucleotide polymorphism (SNP) genotyping assays, and the SNPs were detected on the 7900HT real-time fluorogenic quantitative polymerase chain reaction (PCR) instrument. Finally, the severity of cervical vertigo was classified according to the JOA scoring, and the recovery rate (RR) of cervical vertigo was calculated in light of the formula as: [Formula: see text] RESULTS: The SNPs within ADRA1A [rs1048101 (T>C) and rs3802241 (C>T)], NPY [rs16476 (A>C), rs16148 (T>C), and rs5574 (C>T)], ADRB1 [rs28365031 (A>G)] and ADRB2 [rs2053044 (A>G)] were all significantly associated with regulated risk of cervical vertigo (all P < .05). Haplotypes of ADRA1A [CT and TC] and NPY [CCT and ATT] were also suggested as the susceptible factors of cervical vertigo in comparison with other haplotypes. Furthermore, the SNPs within ADRA1A [rs1048101 (T>C)], NPY [rs16476 (A>C), rs16148 (T>C)], as well as ADRB1 [rs28365031 (A>G)] all appeared to predict the prognosis of cervical vertigo in a relatively accurate way (all P < .05). Ultimately, the haplotypes of ADRA1A (CC) and NPY (CCT) tended to decrease the RR. CONCLUSIONS: The SNPs within ADRB2, ADRB1, NPY, and ADRA1A might act as the diagnostic biomarkers and treatment targets for cervical vertigo. PMID- 29197113 TI - Pyelonephritis in Dogs: Retrospective Study of 47 Histologically Diagnosed Cases (2005-2015). AB - BACKGROUND: The clinicopathologic aspects of pyelonephritis have not been reported in companion animals. HYPOTHESIS/OBJECTIVES: To evaluate the prevalence of pyelonephritis diagnosed in dogs in a academic referral population, describe the clinical signs and the diagnostic test results in dogs with pyelonephritis, and identify concurrent disorders in order to determine potential risk factors for pyelonephritis. ANIMALS: Forty-seven dogs with a histopathologic diagnosis of pyelonephritis from the teaching hospitals of three Canadian veterinary colleges. METHODS: Retrospective case series. Review of medical records and renal histologic sections. RESULTS: Pyelonephritis was diagnosed in 0.4-1.3% of the cases at necropsy. Clinical signs included anorexia or inappetence (n = 27, 57%), lethargy (n = 24, 51%), vomiting (n = 17, 36%), and dehydration (n = 12, 25%). Thirty-five dogs (75%) had concomitant disease(s). Escherichia coli was the most common pathogen isolated (37%). Pyelonephritis was classified as acute (n = 12, 26%), subacute (n = 9, 19%), and chronic (n = 26, 55%) disease; and mild (n = 7, 15%), moderate (n = 11, 24%), and severe (n = 28, 61%). Fever was significantly associated with histopathologically subacute pyelonephritis (P = 0.01). CONCLUSIONS: In referral hospitals, pyelonephritis has a very low prevalence at necropsy. Nonspecific clinical presentation, concomitant diseases, and high variability in the diagnostic tests results make the antemortem diagnosis of pyelonephritis challenging. Neither the histopathologic stage nor the severity of the pyelonephritis was associated with fever, lumbar pain, or signs of a urinary tract infection (ie, lower urinary tract infection, upper urinary tract infection, or both) except for subacute pyelonephritis which was associated with fever.

PMID- 29197115 TI - Effect of Hazardous Alcohol Use During Pregnancy on Growth Outcomes at Birth: Findings from a South African Cohort Study. AB - BACKGROUND: Cohort studies have noted associations between hazardous alcohol use during pregnancy and infant growth outcomes, but many have not controlled for potential psychosocial confounders. To assess the unique contribution of hazardous alcohol use, we examined its effect on infant growth outcomes while controlling for maternal psychosocial stressors and hazardous tobacco and drug use in a cohort of 986 pregnant South African women enrolled into the Drakenstein Child Health Study between 2012 and 2015. METHODS: Data on psychosocial stressors and maternal risk behaviors were collected between 28 and 32 weeks of gestation. Participants were categorized as hazardous alcohol users if they obtained moderate or high scores (>10) on the Alcohol, Smoking and Substance Involvement Screening Test at this assessment or retrospectively reported drinking at least 2 drinks weekly during any trimester of pregnancy. Infant growth outcomes were recorded at delivery. Multivariable regression models examined correlates of hazardous alcohol use and associations between hazardous alcohol use and birth outcomes. RESULTS: Overall, 13% of mothers reported hazardous alcohol use. Recent exposure to intimate partner violence (adjusted odds ratio (aOR) = 2.08; 95% confidence interval (CI): 1.37, 3.18) and hazardous tobacco use (aOR = 5.03; 95% CI: 2.97, 8.52) were significant correlates of hazardous alcohol use. After controlling for potential psychosocial confounders, hazardous alcohol use remained associated with lower infant weight-for-age (B = -0.35, 95% CI: -0.56, 0.14), height-for-age (B = -0.46, 95% CI: -0.76, -0.17), and head-circumference for-age z-scores (B = -0.43, 95% CI: -0.69, -0.17). CONCLUSIONS: Interventions to reduce hazardous alcohol use among pregnant women in South Africa are needed to prevent alcohol-related infant growth restrictions. As these growth deficits may lead to neurodevelopmental consequences, it is critical to identify alcohol related growth restrictions at birth and link exposed infants to early interventions for neurodevelopment. PMID- 29197117 TI - Addition of Allopurinol for Altering Thiopurine Metabolism to Optimize Therapy in Patients with Inflammatory Bowel Disease. AB - Thiopurine drugs, including azathioprine and 6-mercaptopurine, are used commonly in patients with inflammatory bowel disease for maintenance of remission. Although generally well tolerated, adverse effects lead to discontinuation in a significant minority of patients. Pharmacogenomic studies have suggested that metabolic breakdown of azathioprine in an individual is genetically determined. Coupled with the fact that certain thiopurine metabolites, notably 6-thioguanine nucleotide and 6-methylmercaptopurine, are associated with antiinflammatory effects and adverse effects, respectively, some investigators have examined intentionally shunting the metabolism of azathioprine toward increasing 6 thioguanine nucleotide levels by using low doses of the xanthine oxidoreductase inhibitor allopurinol to improve efficacy and decrease toxicity of azathioprine in patients with inflammatory bowel disease. We performed a search of the MEDLINE and Embase databases for basic and clinical research reports of this modality. Pertinent articles were retrieved, reviewed, and assessed by the authors. Case series, cohort studies, and one randomized trial have investigated adding allopurinol to azathioprine therapy in patients with inflammatory bowel disease. Most reports primarily examined metabolite levels in these patients. In general, the literature suggests that this modality was successful at significantly increasing 6-thioguanine nucleotide levels while decreasing 6 methylmercaptopurine levels. Several small reports have suggested that patients with increased 6-thioguanine nucleotide levels had improved symptoms or symptom remission. Adverse effects and discontinuation rates remained similar or were improved in patients who were taking a thiopurine and started allopurinol. In conclusion, the addition of allopurinol may be an option for optimizing thiopurine metabolite production in select patients with low 6-thioguanine nucleotide levels. Appropriate care and monitoring of these patients are mandatory to prevent neutropenia or other adverse effects. PMID- 29197118 TI - Reducing the stigma associated with anorexia nervosa: An evaluation of a social consensus intervention among Australian and Chinese young women. AB - OBJECTIVE: This study examined the effectiveness of a social consensus intervention in reducing stigma toward individuals with anorexia nervosa (AN) among women from Australia and mainland China. Moreover, the different predictions of informational/normative social influence theory and the social identity approach in terms of the effectiveness of the social consensus intervention were investigated. METHOD: Participants were female students from the Australian National University (n = 97) and Central China Normal University (n = 76) who reported their levels of stigma toward a fictional character with AN before and after receiving normative information regarding the attitudes of others toward people with AN. Three experimental conditions of normative information were utilized: in-group, out-group, and neutral. RESULTS: Chinese participants reported higher levels of baseline stigma across all measures than Australian participants. Social consensus was effective in reducing most types of AN stigma, and supported the social identity approach in that improvements in attitudinal, affective, and behavioral aspects of stigma were significantly greater for participants in the in-group (but not the out-group) versus the neutral condition. The effectiveness of the social consensus approach was not moderated by nationality. DISCUSSION: A social consensus approach holds potential as an additional strategy for reducing AN stigma, with its benefits extending across diverse cultural settings. Such an approach would entail ensuring that positive messages regarding people with AN are delivered by members of a valued in-group. PMID- 29197119 TI - Fundamental movement skills in adolescents: Secular trends from 2003 to 2010 and associations with physical activity and BMI. AB - The aim of this study was to examine the secular trends in fundamental movement skills (FMS) among 15- to 16-year-old adolescents at 2 assessment points scheduled in 2003 and 2010 and to investigate the associations between FMS, physical activity (PA), and body mass index (BMI). In 2003, self-reported PA, weight and height, and objective FMS scores were collected from 2390 students, and in 2010, similar data were generated from a second sample of 1346 students. FMS were assessed during both assessment phases using 3 identical objective FMS tests that were figure 8 dribbling, jumping laterally, and coordination track tests. This study indicated that the sum index of FMS did not change among the boys and the girls between 2 data collection points. However, findings demonstrated a secular decline in coordination test scores in both gender groups between 2 measurement points but an improvement in girls' object control skills between 2003 and 2010. The results also showed that FMS had a significant main effect on BMI in both gender groups, whereas the main effect of PA on BMI was not significant for either gender group. Results also demonstrated that there was no significant interaction effect between FMS and PA on BMI in either of the girls' or the boys' groups. PMID- 29197121 TI - The clinical anatomy of fibromyalgia. AB - Fibromyalgia is a disorder characterized by pain and a spectrum of psychological comorbidities, rendering treatment difficult, and often a financial burden. Findings regarding diagnosis, prevalence, comorbidities, and potential pathophysiological links are discussed herein. Fibromyalgia is a complex disorder and there are specific criteria that patients must meet for diagnosis, including scores on fibromyalgia questionnaires, commonalities of age, gender, menopause status, sleep disturbances, and mood symptoms. The close relationship between fibromyalgia and other chronic disorders should alert the physician to explore for comorbid illnesses. In this review of the clinical anatomy of fibromyalgia, we review new studies that could be significant for the current use of clinical interventions for patients with symptoms. Using standard search engines, the clinical anatomy of fibromyalgia is investigated and many related studies are mentioned herein. Fibromyalgia is considered a prototypical central chronic pain syndrome and is associated with widespread pain that fluctuates spontaneously. There is also substantial lifetime psychiatric comorbidity in individuals with fibromyalgia, resulting in a low health-related quality of life. These results have important clinical and theoretical implications, including the possibility that fibromyalgia could share underlying pathophysiological links with some psychiatric disorders. This reveals that patients with fibromyalgia have findings compatible with tissue injury pain, the pain mechanisms involving both the primary afferent neuron and the nociceptive systems in the central nervous system. (1) There is a relationship between fibromyalgia and chronic disorders. This should alert the physician to explore for comorbid illnesses. (2) There is substantial lifetime psychiatric comorbidity resulting in a low health-related quality of life. (3) Patients with fibromyalgia have findings compatible with tissue injury pain Clin.

PMID- 29197120 TI - Resveratrol inhibits obesity-associated adipose tissue dysfunction and tumor growth in a mouse model of postmenopausal claudin-low breast cancer. AB - Adipose tissue dysregulation, a hallmark of obesity, contributes to a chronic state of low-grade inflammation and is associated with increased risk and progression of several breast cancer subtypes, including claudin-low breast tumors. Unfortunately, mechanistic targets for breaking the links between obesity associated adipose tissue dysfunction, inflammation, and claudin-low breast cancer growth have not been elucidated. Ovariectomized female C57BL/6 mice were randomized (n = 15/group) to receive a control diet, a diet-induced obesity (DIO) diet, or a DIO + resveratrol (0.5% wt/wt) diet. Mice consumed these diets ad libitum throughout study and after 6 weeks were orthotopically injected with M Wnt murine mammary tumor cells, a model of estrogen receptor (ER)-negative claudin-low breast cancer. Compared with controls, DIO mice displayed adipose dysregulation and metabolic perturbations including increased mammary adipocyte size, cyclooxygenase-2 (COX-2) expression, inflammatory eicosanoid levels, macrophage infiltration, and prevalence of crown-like structures (CLS). DIO mice (relative to controls) also had increased systemic inflammatory cytokines and decreased adipocyte expression of peroxisome proliferator-activated receptor gamma (PPARgamma) and other adipogenesis-regulating genes. Supplementing the DIO diet with resveratrol prevented obesity-associated increases in mammary tumor growth, mammary adipocyte hypertrophy, COX-2 expression, macrophage infiltration, CLS prevalence, and serum cytokines. Resveratrol also offset the obesity associated downregulation of adipocyte PPARgamma and other adipogenesis genes in DIO mice. Our findings suggest that resveratrol may inhibit obesity-associated inflammation and claudin-low breast cancer growth by inhibiting adipocyte hypertrophy and associated adipose tissue dysregulation that typically accompanies obesity. PMID- 29197123 TI - What is the role of mitochondrial dysfunction in skin photoaging? AB - Skin ageing is a complex process involving both internal and external factors, which leads to a progressive loss of cutaneous function and structure. Solar radiation is the primary environmental factor implicated in the development of skin ageing, and the term photoaging describes the distinct clinical, histological and structural features of chronically sun-exposed skin. The changes that accompany photoaging are undesirable for aesthetic reasons and can compromise the skin and make it more susceptible to a number of dermatological disorders. As a result, skin ageing is a topic that is of growing interest and concern to the general population, illustrated by the increased demand for effective interventions that can prevent or ameliorate the clinical changes associated with aged skin. In this viewpoint essay, we explore the role that mitochondria play in the process of skin photoaging. There is continuing evidence supporting the proposal that mitochondrial dysfunction and oxidative stress are important contributing factors in the development of skin photoaging. Further skin-directed mitochondrial research is warranted to fully understand the impact of mitochondrial status and function in skin health. A greater understanding of the ageing process and the regulatory mechanisms involved could lead to the development of novel preventative interventions for skin ageing. PMID- 29197122 TI - Efficacy of Minocycline in Naturally Occurring Nonacute Ehrlichia canis Infection in Dogs. AB - BACKGROUND: Minocycline has been used in the treatment of Ehrlichia canis infection in dogs as an alternative to doxycycline, the recommended treatment. However, efficacy of this alternative therapy is unknown. OBJECTIVE: To assess the efficacy of minocycline in the treatment of natural occurring E. canis infection in dogs. ANIMALS: Ten privately owned dogs of mixed breed positive for E. canis by blood PCR. METHODS: Prospective, randomized clinical study. Dogs positive for E. canis by PCR were housed in a kennel environment and randomly allocated to receive doxycycline 10 mg/kg bodyweight PO once daily ("gold standard" control group) or minocycline (extralabel) 10 mg/kg bodyweight PO twice daily (treatment test group) for 28 days. Blood, analyzed by PCR to determine the presence or absence of E. canisDNA, was collected weekly during treatment starting on the first day of treatment and including through day 35, 7 days after the last treatment. RESULTS: In both groups, one dog tested negative after 7 days of treatment. For the doxycycline group, the latest time to a negative PCR test was after 3 weeks of treatment. For the minocycline group, the latest time was on day 28 of treatment. All dogs tested negative 7 days after the end of treatment. CONCLUSION AND CLINICAL IMPORTANCE: Minocycline can be an effective alternative to doxycycline for clearing E. canis from the blood in nonacute infections. PMID- 29197124 TI - Breastmilk cell trafficking induces microchimerism-mediated immune system maturation in the infant. AB - Initiating breastfeeding within the first hour of life confers an important benefit in terms of child mortality and severe morbidity. Intestinal permeability to ingested macromolecules and immunoglobulins is limited to the first days of human life. These exchanges cease in the very early post-partum period but may increase beyond the neonatal period in response to local inflammation or introduction of a weaning food. From animal- and limited human-based observations, compelling evidence points out to breastmilk cells also trafficking from mother to infant mucosal tissues and participating to the maternal microchimerism. The precise nature of breastmilk cells that are involved is presently not known but likely includes progenitor/stem cells-representing up to 6% of breastmilk cells-with possible contribution of mature immune cells. Stem cell microchimerism may induce tolerance to non-inherited maternal antigens (NIMAs), breastfeeding generating regulatory T cells (Treg ) that suppress antimaternal immunity. Therefore, in complement to pregnancy-induced microchimerism, breastfeeding-induced microchimerism may be pivotal in infant immune development, intestinal tissue repair/growth and protection against infectious diseases. As a continuum of the gestational period, the neonatal gut may be considered as a temporary, but important developmental extension of the role played by the placenta during intrauterine life; breastmilk playing the role of maternal blood by delivering maternal soluble factors (macromolecules, Ig, cytokines) and immunologically active milk cells. A better understanding of breastfeeding-induced maternal microchimerism would provide further evidence in support of public health messages that reinforce the importance of early initiation of breastfeeding.

AB - Treatment of periodontitis aims to control the infection caused by the periodontal pathogenic flora and includes mechanical debridement of root surfaces to disrupt the supragingival and subgingival biofilm. As periodontal pockets of <= 5 mm can be perform in a stable condition and may not need additional therapy, the ability and the willingness of the patient to perform good oral hygiene on a long-term basis are of utmost importance for ensuring long-term success of periodontal treatment. In this context, the aim of all home-care measures must be the optimal control of plaque biofilm in order to prevent or treat gingival inflammation as a primary stage of periodontitis. Despite the fact that toothbrushing and other mechanical cleaning practices are the most important elements for preventing periodontal diseases or their progression, other factors, including education, motivation, manual dexterity and compliance with professional recommendation, provision of time and socio-economic status, as well as risk factors, play a role. The present article provides an overview on the various possibilities for self-care of residual pockets in patients with periodontitis. PMID- 29197127 TI - Overview of carbon and nitrogen catabolite metabolism in the virulence of human pathogenic fungi. AB - It is estimated that fungal infections, caused most commonly by Candida albicans, Aspergillus fumigatus and Cryptococcus neoformans, result in more deaths annually than malaria or tuberculosis. It has long been hypothesized the fungal metabolism plays a critical role in virulence though specific nutrient sources utilized by human pathogenic fungi in vivo has remained enigmatic. However, the metabolic utilisation of preferred carbon and nitrogen sources, encountered in a host niche dependent manner, is known as carbon catabolite and nitrogen catabolite repression (CCR, NCR), and has been shown to be important for virulence. Several sensory and uptake systems exist, including carbon and nitrogen source-specific sensors and transporters, that allow scavenging of preferred nutrient sources. Subsequent metabolic utilisation is governed by transcription factors, whose functions and essentiality differ between fungal species. Furthermore, additional factors exist that contribute to the implementation of CCR and NCR. The role of the CCR and NCR-related factors in virulence varies greatly between fungal species and a substantial gap in knowledge exists regarding specific pathways. Further elucidation of carbon and nitrogen metabolism mechanisms is therefore required in a fungal species- and animal model-specific manner in order to screen for targets that are potential candidates for anti-fungal drug development. PMID- 29197128 TI - A Remote Assay for Measuring Canine Platelet Activation and the Inhibitory Effects of Antiplatelet Agents. AB - BACKGROUND: Antiplatelet medications are increasingly used in dogs. Remote analysis of platelet activity is challenging, limiting assessment of antiplatelet drug efficacy. HYPOTHESIS/OBJECTIVES: To evaluate a method used in humans for stimulation and remote analysis of canine platelet activity. ANIMALS: Forty-five dogs of various ages without a coagulopathy or thrombocytopenia. Six were receiving antiplatelet medication. METHODS: Prospective observational study. Platelets were stimulated with combinations of arachidonic acid (AA) and epinephrine (Epi) or adenosine diphosphate (ADP) and the thromboxane A2 -mimetic U46619 (U4). PAMFix was added to the blood samples to facilitate delayed analysis of platelet activity. Activity was assessed by flow cytometric measurement of surface P-selectin (CD62P) expression. RESULTS: Canine platelets could be stimulated with both AA/Epi and ADP/U4. The levels of P-selectin were significantly greater than paired, unstimulated samples (P < 0.001). Inhibition of P-selectin expression occurred after this stimulation by adding antiplatelet drugs in vitro. The efficacy of antiplatelet drugs in samples from treated dogs was also measurable ex vivo using this method. Delayed analysis of platelet activity at time points up to 22 days demonstrated excellent correlation between respective mf values at each time point (r2 = 0.92, P < 0.0001). CONCLUSIONS AND CLINICAL IMPORTANCE: This study evaluated a new method to remotely assess canine platelet activity. It shows that PAMFix can be used for this purpose. This provides opportunities to interrogate the inhibitory action of antiplatelet drugs in clinical settings.

PMID- 29197131 TI - 3D reconstruction of peripheral nerves from optical projection tomography images: A method for studying fascicular interconnections and intraneural plexuses. AB - The general microscopic characteristics of nerves are described in several textbooks of histology, but the specific microanatomies of most nerves that can be blocked by anesthesiologists are usually less well known. Our objective was to evaluate the 3D reconstruction of nerve fascicles from optical projection tomography images (OPT) and the ability to undertake an internal navigation exploring the morphology in detail, more specifically the fascicular interconnections. Median and lingual nerve samples were obtained from five euthanized piglets. OPT images of the samples were acquired and 3D reconstruction was performed. The OPT technique revealed the inner structure of the nerves at high resolution, including large and small fascicles, perineurium, interfascicular tissue, and epineurium. The fascicles were loosely packed inside the median nerve and more densely so in the lingual nerve. Analysis of the 3D models demonstrated that the nerve fascicles can show six general spatial patterns. Fascicular interconnections were clearly identified. The 3D reconstruction of nerve fascicles from OPT images opens a new path for research into the microstructure of the inner contents of fascicular nerve groups and their spatial disposition within the nerve including their interconnections. These techniques enable 3D images of partial areas of nerves to be produced and could became an excellent tool for obtaining data concerning the 3D microanatomy of nerves, essential for better interpretation of ultrasound images in clinical practice and thus avoiding possible neurological complications.

The B16 melanoma cell line was transduced with a recombinant lentiviral vector containing the HSV1-tk gene and inoculated into the back skin of C57BL/6J mice. [18 F]FHBG PET imaging showed better contrast for HSV1-tk(+) melanomas compared to brain, heart, gall bladder, intestine and kidney than did [18 F]FDG PET imaging. PMID- 29197133 TI - Perceptions of the dental profession: a comparative analysis through scale development. AB - Dentistry is a science-based profession that has a close interaction with people and society. However, despite this close interaction, perceptions of the dental profession by both patients and dental professionals have received little research attention. The purpose of this study was to compare the perceptions of dentists, dental students, and patients toward the dental profession through the development and testing of the Dental Profession Perceptions Scale (DPPS). The DPPS contains a total of 17 items measured on a 5-point Likert response scale. The DPPS showed excellent internal reliability (Cronbach's alpha = 0.92) and test retest reliability (r = 0.93). Explanatory and confirmatory factor analyses of the DPPS showed that dentists', dental students', and patients' perceptions of the dental profession could be grouped according to 'status', 'human', and 'scientific' factors. There were no statistically significant differences between participants' DPPS total or sub-scale scores according to dental group, gender, or income. The DPPS developed can be used in future studies as a psychometrically sound measuring tool. Further studies should examine the factors that may affect the perceptions of the dental profession in different societies and cultures. PMID- 29197134 TI - Assessment of cardiovascular risk in an Italian psychiatric outpatient sample: A chart review of patients treated with second-generation antipsychotics. AB - Despite the call by the scientific community for a systematic monitoring of physical health in people with psychiatric illnesses, national and international audits have reported poor quality of cardiovascular risk assessments and management in this vulnerable population. Available evidence indicates that in people affected by mental illness, life expectancy is reduced by 10-20 years, mainly due to cardiovascular accidents and metabolic syndrome (MetS)-related diseases. The primary aim of the present study was to evaluate the accuracy of cardiovascular risk monitoring in an outpatient sample of patients taking second generation antipsychotics. The sample consisted of 200 patients consecutively recruited from two community mental health centres. A clinical chart review was performed on the following laboratory tests: total cholesterol, high- and low density lipoprotein, serum triglycerides, fasting blood glucose, gamma-glutamyl transpeptidase. Blood pressure and waist circumference were measured. A complete cardiovascular risk assessment was available only in 60 patients out of 200 (33.3%). The only variable associated with laboratory tests for MetS was receiving three or more psychotropic medications, which increased fourfold the probability of metabolic screening. In the subsample of patients with full screening, the prevalence of MetS was 33.3%. Our findings suggest that mental health professionals working in community mental health services should incorporate a more systematic assessment of physical health in their practice, and intervene proactively to reduce the significant cardiovascular burden carried by people with several mental illness.

This has included the extended use of adult continuous-flow devices in the pediatric population. In a minority of cases, biventricular support may be needed. In these situations, biventricular support with continuous-flow devices can be surgically challenging, and therefore, only few cases have been reported. Here, we present a case of implantation of two HeartWare HVAD devices for biventricular support for a decompensating patient with acute myocarditis as well as present an alternative implantation surgical strategy. PMID- 29197136 TI - Properties of human genes guided by their enrichment in rare and common variants. AB - We analyzed 563,099 common (minor allele frequency, MAF>=0.01) and rare (MAF < 0.01) genetic variants annotated in ExAC and UniProt and 26,884 disease-causing variants from ClinVar and UniProt occurring in the coding region of 17,975 human protein-coding genes. Three novel sets of genes were identified: those enriched in rare variants (n = 32 genes), in common variants (n = 282 genes), and in disease-causing variants (n = 800 genes). Genes enriched in rare variants have far greater similarities in terms of biological and network properties to genes enriched in disease-causing variants, than to genes enriched in common variants. However, in half of the genes enriched in rare variants (AOC2, MAMDC4, ANKHD1, CDC42BPB, SPAG5, TRRAP, TANC2, IQCH, USP54, SRRM2, DOPEY2, and PITPNM1), no disease-causing variants have been identified in major, publicly available databases. Thus, genetic variants in these genes are strong candidates for disease and their identification, as part of sequencing studies, should prompt further in vitro analyses. PMID- 29197137 TI - Immunohistopathological characterization and the impact of topical immunomodulatory therapy in oral chronic graft-versus-host disease: A pilot study. AB - OBJECTIVE: To characterize the immunohistopathological features of oral chronic graft-versus-host disease (cGVHD), and the impact of topical immunomodulatory therapy on the infiltrating cells. MATERIAL AND METHODS: Paired oral cGVHD biopsies obtained before (n = 12) and 1 month after treatment (n = 12) with topical dexamethasone (n = 8) or tacrolimus (n = 4) were characterized by immunohistochemistry using a panel of CD1a, CD3, CD4, CD8, CD20, CD31, CD62E, CD103, CD163, c-kit, and FoxP3. Controls included acute GVHD (aGVHD; n = 3), oral lichen planus (OLP; n = 5), and normal tissues (n = 5). RESULTS: Oral cGVHD specimens prior to treatment were mainly characterized by basal cell squamatization, lichenoid inflammation, sclerosis, apoptosis, and lymphocytic exocytosis. The infiltrating cells in oral cGVHD primarily consisted of CD3+ , CD4+ , CD8+ , CD103+ , CD163+ , and FoxP3+ cells, which were higher than in normal tissues. Topical dexamethasone or tacrolimus reduced neutrophilic exocytosis, basal cell squamatization, and lichenoid inflammation in oral cGVHD, and dexamethasone reduced the number of CD4+ and CD103+ cells. CONCLUSION: The high expression of CD3, CD4, CD8, CD103, CD163, and FoxP3 confirms that oral cGVHD is largely T-cell-driven with macrophage participation. The impact of topical immunomodulatory therapy was variable, reducing histological inflammatory features, but with a weak clinicopathological correlation. Topical dexamethasone reduced the expression of CD4 and CD103, which may offer novel therapeutic targets. PMID- 29197138 TI - Testicular orphan receptor 4 promotes tumor progression and implies poor survival through AKT3 regulation in seminoma. AB - Seminoma is the most common testicular germ cell tumor worldwide and mainly occurs in 15-35-year-old young men. Early studies have indicated that testicular nuclear receptor 4 (TR4) first cloned from testis is involved in the invasion and metastasis of several human tumors; however, little attention is paid to the function of TR4 in seminoma. Our immunohistochemical (IHC) staining results showed that patients with advanced stage tumors tended to have higher expression of TR4. Importantly, there was a significant association between elevated TR4 expression and reduced overall survival in seminoma patients. In vitro MTS, western blot and transwell assays, after manipulating TR4 expression in Tcam-2 cells, revealed that TR4 induced epithelial-to-mesenchymal transition (EMT) and promoted Tcam-2 cell proliferation and invasion. Mechanism dissection demonstrated that AKT3, a critical component in the signaling pathway, played a crucial role in mediating TR4-promoted Tcam-2 cell proliferation and invasion. We further revealed that TR4 modulated AKT3 at the transcriptional level via chromatin immunoprecipitation and luciferase assays. Meanwhile, addition of the AKT3 siRNA blocked the function of TR4. Overall, these findings first elucidate that TR4 is a novel prognostic marker and plays a critical role in the metastatic capacity of Tcam-2 cells by EMT regulation and, consequently, targeting TR4-AKT3 pathway may serve as a potential therapeutic approach for seminoma.
